TI Patterns of primary care and mortality among patients with schizophrenia

healthcare utilization

AB Background: Patients with schizophrenia have difficulty managing their medical healthcare needs, possibly resulting in delayed treatment and poor outcomes. We analyzed whether patients reduced primary care use over time, differentially by diagnosis with schizophrenia, diabetes, or both schizophrenia and diabetes. We also assessed whether such patterns of primary care use were a significant predictor of mortality over a 4-year period.
Methods: The Veterans Healthcare Administration (VA) is the largest integrated healthcare system in the United States. Administrative extracts of the VA's all-electronic medical records were studied. Patients over age 50 and diagnosed with schizophrenia in 2002 were age-matched 1:4 to diabetes patients. All patients were followed through 2005. Cluster analysis explored trajectories of primary care use. Proportional hazards regression modelled the impact of these primary care utilization trajectories on survival, controlling for demographic and clinical covariates.
Results: Patients comprised three diagnostic groups: diabetes only (n = 188,332), schizophrenia only (n = 40,109), and schizophrenia with diabetes (Scz-DM, n = 13,025). Cluster analysis revealed four distinct trajectories of primary care use: consistent over time, increasing over time, high and decreasing, low and decreasing. Patients with schizophrenia only were likely to have low-decreasing use (73% schizophrenia-only vs 54% Scz-DM vs 52% diabetes). Increasing use was least common among schizophrenia patients (4% vs 8% Scz-DM vs 7% diabetes) and was associated with improved survival. Low-decreasing primary care, compared to consistent use, was associated with shorter survival controlling for demographics and case-mix. The observational study was limited by reliance on administrative data.
Conclusion: Regular primary care and high levels of primary care were associated with better survival for patients with chronic illness, whether psychiatric or medical. For schizophrenia patients, with or without comorbid diabetes, primary care offers a survival benefit, suggesting that innovations in treatment retention targeting at-risk groups can offer significant promise of improving outcomes.

AB Multiple myeloma is characterised by clonal proliferation of malignant plasma cells, and mounting evidence indicates that the bone marrow microenvironment of tumour cells has a pivotal role in myeloma pathogenesis. This knowledge has already expanded treatment options for patients with multiple myeloma. Prototypic drugs thalidomide, bortezomib, and lenalidomide have each been approved for the treatment of this disease by targeting both multiple myeloma cells and the bone marrow microenvironment. Although benefit was first shown in relapsed and refractory disease, improved overall response, duration of response, and progression-free and overall survival can be achieved when these drugs are part of first-line regimens. This treatment framework promises to improve outcome not only for patients with multiple myeloma, but also with other haematological malignancies and solid tumours.

AB Purpose: The pathophysiology of diabetic retinopathy involves leukocyte adhesion to retinal vasculature, early blood-retinal barrier breakdown, capillary nonperfusion, and endothelial cell death. We investigated the involvement of tumor necrosis factor alpha (TNF-alpha) in diabetes-related histopathological changes in two relevant rodent models.
Methods: In short-term studies, Long-Evans rats with streptozotocin-induced diabetes were treated with or without the TNF-alpha inhibitor, etanercept. For long-term studies, tumor necrosis factor receptor I (TNF-RI)-deficient mice and TNF-RII-deficient mice, as well as C57/Bl6 wild-type mice, were fed 30% galactose for up to 20 months. The retinal histopathological alterations of hypergalactosemia were analyzed in trypsin digest preparations. Endothelial cell injury and apoptosis in rat retinas were evaluated by propidium iodide, TUNEL, CytoDeath staining, and DNA fragmentation ELISA. Caspase 3 and 8 activity was evaluated by immunoblotting and quantitative enzymatic activity assay.
Results: Etanercept suppressed caspase activation, retinal cell injury, and apoptosis in short-term diabetic rats. Pericyte and endothelial cell loss were also reduced in long-term hypergalactosemic mice. Long-term studies demonstrated that pericyte loss and endothelial cell loss were reduced in comparison to wild-type diabetic controls.
Conclusions: Our study identifies an important role for TNF-alpha in the pathogenesis of signature diabetic retinopathy pathologies and demonstrates that etanercept can inhibit retinal cell death and long-term complication of diabetes. Taken together, our results suggest that etanercept could prove beneficial in preventing both early and late vascular diabetic complications.

AB Monodisperse iron oxide/microporous silica core/shell composite nanoparticles, core(gamma-Fe2O3)/shell(SiO2), with a diameter of approximately 100 nm and a high magnetization are synthesized by combining sol-gel chemistry and supercritical fluid technology. This one-step processing method, which is easily scalable, allows quick fabrication of materials with controlled properties and in high yield. The particles have a specific magnetic moment (per kg of iron) comparable to that of the bulk maghemite and show superparamagnetic behavior at room temperature. The nanocomposites are proven to be useful as T-2 MRI imaging agent. They also have potential to be used in NMR proximity sensing, theranostic drug delivery, and bioseparation.

AB Changes in expression levels of genes encoding for proteins that control metabolic pathways are essential to maintain nutrient and energy homeostasis in individual cells as well as in organisms. An important regulated step in this process is accomplished through covalent chemical modifications of proteins that form complexes with the chromatin of gene promoters. The peroxisome proliferators gamma co-activator 1 (PGC-1) family of transcriptional co-activators comprises important components of a number of these complexes and participates in a large array of glucose and lipid metabolic adaptations. Here, we show that PGC-1 beta is acetylated on at least 10 lysine residues distributed along the length of the protein by the acetyl transferase general control of amino-acid synthesis (GCN5) and that this acetylation reaction is reversed by the deacetylase sirtuin 1 (SIRT1). GCN5 strongly interacts with PGC-1 beta and represses its transcriptional activity associated with transcription factors such as ERR alpha, NRF-1, and HNF4 alpha, however acetylation and transcriptional repression do not occur when a catalytically inactive GCN5 is co-expressed. Transcriptional repression coincides with PGC-1 beta redistribution to nuclear foci where it co-localizes with GCN5. Furthermore, knockdown of GCN5 ablates PGC-1 beta acetylation and increases transcriptional activity. In primary skeletal muscle cells, PGC-1 beta induction of endogenous target genes, including MCAD and GLUT4, is largely repressed by GCN5. Functionally, this translates to a blunted response to PGC-1 beta-induced insulin-mediated glucose transport. These results suggest that PGC-1 beta acetylation by GCN5 might be an important step in the control of glucose and lipid pathways and its dysregulation could contribute to metabolic diseases.

MACROAUTOPHAGY
AB Continuous macroautophagic activity is critical for the maintenance of neuronal homeostasis; however, unchecked or dysregulated autophagy can lead to cell death. Cultured Purkinje neurons die by an autophagy-associated cell death mechanism when deprived of trophic support. Here, we report that insulin-like growth factor-I ( IGF-I) completely blocked the autophagy-associated cell death of Purkinje neurons. To examine the mechanism by which IGF-I influences autophagy, neurons were infected with adeno-RFP-LC3 and subjected to trophic factor withdrawal, and the size and number of autophagosomes were analyzed by live-cell fluorescence imaging. In control neurons, autophagy occurred at a constitutive low level with most autophagosomes measuring less than 0.75 mu m. Trophic factor withdrawal increased the number and size of autophagosomes with most autophagosomes ranging between 0.75 and 1.5 mu m and some reaching 1.5-2.25 mu m. IGF-I added at the time of trophic factor withdrawal prevented the accumulation of the larger autophagosomes; however, it had no effect on the conversion of LC3, an indicator of autophagy induction. Instead, the rate of autophagosome-to-lysosome fusion measured by colocalization of RFP-LC3 and LysoSensor Green was accelerated by IGF-I. Treating the neurons with bafilomycin A(1) in the presence of IGF-I led to the accumulation of autophagosomes even larger than those induced by trophic factor withdrawal alone, indicating that IGF-I regulates autophagic vesicle turnover. Finally, the effect of IGF-I on autophagy was mediated by an Akt/mTOR-dependent and an ERK-independent pathway. These data suggest a novel role for IGF-I in protecting Purkinje neurons from autophagy-associated cell death by increasing autophagy efficiency downstream of autophagy induction.

In the past decade, an avalanche of research has shown that many real networks, independent of their age, function, and scope, converge to similar architectures, a universality that allowed researchers from different disciplines to embrace network theory as a common paradigm. The decade-old discovery of scale-free networks was one of those events that had helped catalyze the emergence of network science, a new research field with its distinct set of challenges and accomplishments.

AB Lenalidomide plus dexamethasone is effective for the treatment of relapsed and refractory multiple myeloma (MM); however, toxicities from dexamethasone can be dose limiting. We evaluated the efficacy and safety of lenalidomide monotherapy in patients with relapsed and refractory MM. Patients (N = 222) received lenalidomide 30 mg/day once daily (days 1-21 every 28 days) until disease progression or intolerance. Response, progression-free survival (PFS), overall survival (OS), time to progression (TTP), and safety were assessed. Overall, 67% of patients had received 3 or more prior treatment regimens. Partial response or better was reported in 26% of patients, with minimal response 18%. There was no difference between patients who had received 2 or fewer versus 3 or more prior treatment regimens (45% vs 44%, respectively). Median values for TTP, PFS, and OS were 5.2, 4.9, and 23.2 months, respectively. The most common grade 3 or 4 adverse events were neutropenia (60%), thrombocytopenia (39%), and anemia (20%), which proved manageable with dose reduction. Grade 3 or 4 febrile neutropenia occurred in 4% of patients. Lenalidomide monotherapy is active in relapsed and refractory MM with acceptable toxicities. These data support treatment with single-agent lenalidomide, as well as its use in steroid-sparing combination approaches. The study is registered at http://www.clinicaltrials.gov as NCT00065351.

TI Androgen Receptor Regulates a Distinct Transcription Program in

AB The evolution of prostate cancer from an androgen-dependent state to one that is androgen-independent marks its lethal progression. The androgen receptor (AR) is essential in both, though its function in androgen-independent cancers is poorly understood. We have defined the direct AR-dependent target genes in both androgen-dependent and -independent cancer cells by generating AR-dependent gene expression profiles and AR cistromes. In contrast to what is found in androgen-dependent cells, AR selectively upregulates M-phase cell-cycle genes in androgen-independent cells, including UBE2C, a gene that inactivates the M-phase checkpoint. We find that epigenetic marks at the UBE2C enhancer, notably histone H3K4 methylation and FoxA1 transcription factor binding, are present in androgen-independent cells and direct AR-enhancer binding and UBE2C activation. Thus, the role of AR in androgen-independent cancer cells is not to direct the androgen-dependent gene expression program without androgen, but rather to execute a distinct program resulting in androgen-independent growth.

AB Cyclins are regulatory subunits of cyclin-dependent kinases. Cyclin A, the first cyclin ever cloned, is thought to be an essential component of the cell-cycle engine. Mammalian cells encode two A-type cyclins, testis-specific cyclin A1 and ubiquitously expressed cyclin A2. Here, we tested the requirement for cyclin A function using conditional knockout mice lacking both A-type cyclins. We found that acute ablation of cyclin A in fibroblasts did not affect cell proliferation, but led to prolonged expression of another cyclin, cyclin E, across the cell cycle. However, combined ablation of all A- and E-type cyclins extinguished cell division. In contrast, cyclin A function was essential for cell-cycle progression of hematopoietic and embryonic stem cells. Expression of cyclin A is particularly high in these compartments, which might render stem cells dependent on cyclin A, whereas in fibroblasts cyclins A and E play redundant roles in cell proliferation.

AB Background
Profound hearing loss is a serious complication of neurofibromatosis type 2, a genetic condition associated with bilateral vestibular schwannomas, benign tumors that arise from the eighth cranial nerve. There is no medical treatment for such tumors.
Methods
We determined the expression pattern of vascular endothelial growth factor (VEGF) and three of its receptors, VEGFR-2, neuropilin-1, and neuropilin-2, in paraffin-embedded samples from 21 vestibular schwannomas associated with neurofibromatosis type 2 and from 22 sporadic schwannomas. Ten consecutive patients with neurofibromatosis type 2 and progressive vestibular schwannomas who were not candidates for standard treatment were treated with bevacizumab, an anti-VEGF monoclonal antibody. An imaging response was defined as a decrease of at least 20% in tumor volume, as compared with baseline. A hearing response was defined as a significant increase in the word-recognition score, as compared with baseline.
Results
VEGF was expressed in 100% of vestibular schwannomas and VEGFR-2 in 32% of tumor vessels on immunohistochemical analysis. Before treatment, the median annual volumetric growth rate for 10 index tumors was 62%. After bevacizumab treatment in the 10 patients, tumors shrank in 9 patients, and 6 patients had an imaging response, which was maintained in 4 patients during 11 to 16 months of follow-up. The median best response to treatment was a volumetric reduction of 26%. Three patients were not eligible for a hearing response; of the remaining seven patients, four had a hearing response, two had stable hearing, and one had progressive hearing loss. There were 21 adverse events of grade 1 or 2.
Conclusions
VEGF blockade with bevacizumab improved hearing in some, but not all, patients with neurofibromatosis type 2 and was associated with a reduction in the volume of most growing vestibular schwannomas.

AB Objectives
This study sought to evaluate the use of a continuous-flow rotary left ventricular assist device (LVAD) as a bridge to heart transplantation.
Background
LVAD therapy is an established treatment modality for patients with advanced heart failure. Pulsatile LVADs have limitations in design precluding their use for extended support. Continuous-flow rotary LVADs represent an innovative design with potential for small size and greater reliability by simplification of the pumping mechanism.
Methods
In a prospective, multicenter study, 281 patients urgently listed (United Network of Organ Sharing status 1A or 1B) for heart transplantation underwent implantation of a continuous-flow LVAD. Survival and transplantation rates were assessed at 18 months. Patients were assessed for adverse events throughout the study and for quality of life, functional status, and organ function for 6 months.
Results
Of 281 patients, 222 (79%) underwent transplantation, LVAD removal for cardiac recovery, or had ongoing LVAD support at 18-month follow-up. Actuarial survival on support was 72% (95% confidence interval: 65% to 79%) at 18 months. At 6 months, there were significant improvements in functional status and 6-min walk test (from 0% to 83% of patients in New York Heart Association functional class I or II and from 13% to 89% of patients completing a 6-min walk test) and in quality of life (mean values improved 41% with Minnesota Living With Heart Failure and 75% with Kansas City Cardiomyopathy questionnaires). Major adverse events included bleeding, stroke, right heart failure, and percutaneous lead infection. Pump thrombosis occurred in 4 patients.
Conclusions
A continuous-flow LVAD provides effective hemodynamic support for at least 18 months in patients awaiting transplantation, with improved functional status and quality of life.

AB Objective: To develop a late-life dementia risk index that can accurately stratify older adults into those with a low, moderate, or high risk of developing dementia within 6 years.
Methods: Subjects were 3,375 participants in the Cardiovascular Health Cognition Study without evidence of dementia at baseline. We used logistic regression to identify those factors most predictive of developing incident dementia within 6 years and developed a point system based on the logistic regression coefficients.
Results: Subjects had a mean age of 76 years at baseline; 59% were women and 15% were African American. Fourteen percent (n = 480) developed dementia within 6 years. The final late-life dementia risk index included older age (1-2 points), poor cognitive test performance (2-4 points), body mass index <18.5 (2 points), >= 1 apolipoprotein E epsilon 4 alleles (1 point), cerebral MRI findings of white matter disease (1 point) or ventricular enlargement (1 point), internal carotid artery thickening on ultrasound (1 point), history of bypass surgery (1 point), slow physical performance (1 point), and lack of alcohol consumption (1 point) (c statistic, 0.81; 95% confidence interval, 0.79-0.83). Four percent of subjects with low scores developed dementia over 6 years compared with 23% of subjects with moderate scores and 56% of subjects with high scores.
Conclusions: The late-life dementia risk index accurately stratified older adults into those with low, moderate, and high risk of developing dementia. This tool could be used in clinical or research settings to target prevention and intervention strategies toward high-risk individuals. Neurology (R) 2009; 73: 173-179

AB Dose in radiation therapy is traditionally reported as the water-equivalent dose, or dose to water. Monte Carlo dose calculations report dose to medium and thus a methodology is needed to convert dose to medium into dose to water (or vice versa) for comparison of Monte Carlo results with results from planning systems. This paper describes the development of a formalism to convert dose to medium into dose to water for proton fields when simulating the dose with Monte Carlo techniques. The conversion is based on relative stopping power but also considers energy transferred via nuclear interactions. The influence of different interaction mechanisms of proton beams (electromagnetic versus nuclear) is demonstrated. Further, an approximate method for converting doses retroactively is presented. Based on the outlined formalism, five proton therapy patients with a total of 33 fields were analyzed. Dose distributions, dose volume histograms and absolute doses to assess the clinical significance of differences between dose to medium and dose to water are presented. We found that the difference between the two dose reporting definitions can be up to 10% for high CT numbers if analyzing the mean dose to the target. The difference is clinically insignificant for soft tissues. For the structures analyzed, the mean dose to water could be converted to dose to medium by applying a correction factor increasing linearly with increasing average CT number in the volume. We determined that an approximate conversion method, done retroactively with an energy-independent stopping power ratio and without considering nuclear interaction events separately (as compared to on-the-fly conversion during simulation), is sufficiently accurate to compute mean doses. It is insufficient, however, when analyzing the beam range. For proton beams stopping in bony anatomy, the predicted beam range can differ by 2-3 mm when comparing dose to tissue and dose to water.

TI Breathing interplay effects during proton beam scanning: simulation and
statistical analysis
SO PHYSICS IN MEDICINE AND BIOLOGY
LA English

ID ORGAN MOTION; IMRT TREATMENTS; RADIOTHERAPY; LUNG
AB Treatment delivery with active beam scanning in proton radiation therapy introduces the problem of interplay effects when pencil beam motion occurs on a similar time scale as intra-fractional tumor motion. In situations where fractionation may not provide enough repetition to blur the effects of interplay, repeated delivery or 'repainting' of each field several times within a fraction has been suggested. The purpose of this work was to investigate the effectiveness of different repainting strategies in proton beam scanning. To assess the dosimetric impact of interplay effects, we performed a series of simulations considering the following parameters: tumor motion amplitude, breathing period, asymmetry in the motion trajectory for the target and time required to change the beam energy for the delivery system. Several repainting strategies were compared in terms of potential vulnerability to a dose delivery error. Breathing motion perpendicular to the beam direction (representing superior-inferior type tumor motion in patients) was considered and modeled as an asymmetric sine function with a peak-to-peak amplitude of between 10 and 30 mm. The results show that motion effects cause a narrowing of the high-dose profile and widening of the penumbra. The 90% isodose area was reduced significantly when considering a large motion amplitude of 3 cm. The broadening of the penumbra appears to depend only on the amplitude of tumor motion (assuming harmonic motion). The delivered dose exhibits a shift of 10-15% of the tumor amplitude (or 1-5 mm) in the caudal direction due to breathing asymmetry observed for both sin(4)(x) and sin(6)(x) motion. Of the five repainting techniques studied, so-called 'breath sampling' turned out to be most effective in reducing dose errors with a minimal increase in treatment time. In this method, each energy level is repainted at several evenly spaced times within one breathing period. To keep dose delivery errors below 5% while minimizing treatment time, it is recommended that breath sampling repainting be employed using 5-10 paintings per field for an assumed tumor volume of 8.5 x 8.5 x 10 cm(3).For smaller tumor volumes more repaintings will be required, while for larger volumes five repaintings should be sufficient to achieve the required dose accuracy.

AB A number of distinct beta-amyloid (A beta) variants or multimers have been implicated in Alzheimer's disease (AD), and antibodies recognizing such peptides are in clinical trials. Humans have natural A beta-specific antibodies, but their diversity, abundance, and function in the general population remain largely unknown. Here, we demonstrate with peptide microarrays the presence of natural antibodies against known toxic A beta and amyloidogenic non-A beta species in plasma samples and cerebrospinal fluid of AD patients and healthy controls aged 21-89 years. Antibody reactivity was most prominent against oligomeric assemblies of A beta and pyroglutamate or oxidized residues, and IgGs specific for oligomeric preparations of A beta 1-42 in particular declined with age and advancing AD. Most individuals showed unexpected antibody reactivities against peptides unique to autosomal dominant forms of dementia (mutant A beta, ABri, ADan) and IgGs isolated from plasma of AD patients or healthy controls protected primary neurons from A beta toxicity. Aged vervets showed similar patterns of plasma IgG antibodies against amyloid peptides, and after immunization with A beta the monkeys developed high titers not only against A beta peptides but also against ABri and ADan peptides. Our findings support the concept of conformation-specific, cross-reactive antibodies that may protect against amyloidogenic toxic peptides. If a therapeutic benefit of A beta antibodies can be confirmed in AD patients, stimulating the production of such neuroprotective antibodies or passively administering them to the elderly population may provide a preventive measure toward AD.

AB Resistance to anoikis, the subtype of apoptosis triggered by lack of adhesion, contributes to malignant transformation and the development of metastasis. Although several lines of evidence suggest that p53 plays a critical role in anoikis, the pathway(s) that connect cell detachment to p53 remain undefined. Here, through the use of a kinome-wide loss-of-function screen, we identify the serine-threonine kinase SIK1 (salt-inducible kinase 1) as a regulator of p53-dependent anoikis. Inactivation of SIK1 compromised p53 function in anoikis and allowed cells to grow in an anchorage-independent manner. In vivo, SIK1 loss facilitated metastatic spread and survival of disseminated cells as micrometastases in lungs. The presence of functional SIK1 was required for the activity of the kinase LKB1 in promoting p53-dependent anoikis and suppressing anchorage-independent growth, Matrigel invasion, and metastatic potential. In human cancers, decreased expression of the gene encoding SIK1 closely correlated with development of distal metastases in breast cancers from three independent cohorts. Together, these findings indicate that SIK1 links LKB1 to p53-dependent anoikis and suppresses metastasis.

AB Bundles of filamentous actin (F-actin) deposited on a gold-plated surface were concurrently imaged using atomic force microscopy (AFM) and surface potential microscopy (SPM). The surface potential was mapped as a function of tip distance to surface using a constant bias potential. There was an uneven spatial distribution of charges detected by SPM, consistent with the segmented topological features shown by AFM of the actin bundles. SPM analysis showed localized changes in surface potential between the axial and transversal sections of the bundles, which are consistent with nonuniform charge distributions of adsorbed salt ions on F-actin.

AB Background: Gene expression profiling of small numbers of cells requires high-fidelity amplification of sub-nanogram amounts of RNA. Several methods for RNA amplification are available; however, there has been little consideration of the accuracy of these methods when working with very low-input quantities of RNA as is often required with rare clinical samples. Starting with 250 picograms-3.3 nanograms of total RNA, we compared two linear amplification methods 1) modified T7 and 2) Arcturus RiboAmp HS and a logarithmic amplification, 3) Balanced PCR. Microarray data from each amplification method were validated against quantitative real-time PCR (QPCR) for 37 genes.
Results: For high intensity spots, mean Pearson correlations were quite acceptable for both total RNA and low-input quantities amplified with each of the 3 methods. Microarray filtering and data processing has an important effect on the correlation coefficient results generated by each method. Arrays derived from total RNA had higher Pearson's correlations than did arrays derived from amplified RNA when considering the entire unprocessed dataset, however, when considering a gene set of high signal intensity, the amplified arrays had superior correlation coefficients than did the total RNA arrays.
Conclusion: Gene expression arrays can be obtained with sub-nanogram input of total RNA. High intensity spots showed better correlation on array-array analysis than did unfiltered data, however, QPCR validated the accuracy of gene expression array profiling from low-input quantities of RNA with all 3 amplification techniques. RNA amplification and expression analysis at the sub-nanogram input level is both feasible and accurate if data processing is used to focus attention to high intensity genes for microarrays or if QPCR is used as a gold standard for validation.

AB Purpose We have demonstrated that patients with HER2-amplified tumors derive more benefit from higher doses of doxorubicin-containing chemotherapy (cyclophosphamide, doxorubicin, and fluorouracil [CAF]). Because topoisomerase II alpha(Topo-II alpha) is a target for doxorubicin and is coamplified in 20% to 50% of HER2-amplified tumors, we postulated that Topo-II alpha copy number might account for the benefit from CAF dose escalation in HER2-positive tumors. To address this hypothesis, we examined Topo-II alpha and HER2 copy number, CAF dose, and clinical outcomes in Cancer and Leukemia Group B (CALGB) 8541.
Patients and Methods Topo-II alpha and HER2 copy number were measured by fluorescent in situ hybridization (FISH) using a triple-probe system, which includes Topo-II alpha, HER2, and chromosome 17 (CEP17). Topo-II alpha and/or HER2 were classified as amplified (>= two copies/CEP17, deleted (<= 0.67 copies/CEP17) and normal copy number (> .67 to < 2.0 copies/CEP17).
Results Topo-II alpha/HER2/CEP17 measurement was successful in 624 of 687 cases. HER2 was amplified in 117 cases (19%). Topo-II alpha was amplified in 41 cases (7%) and deleted in 69 cases (11%). Topo-II alpha amplification was highly correlated with HER2 amplification (39 of 41; P < .0001), HER2 by immunohistochemistry, and by dual-probe FISH. Topo-II alpha was deleted in both the HER2-amplified (30 of 69; 43%), normal (22 of 69; 32%) and HER2-deleted tumors (17 of 69; 25%). Although Topo-II alpha-amplified tumors were nearly always HER2 amplified, these tumors did not receive benefit from increasing the dose of CAF (P = .15).
Conclusion The correlative companion study CALGB 8541-150013 does not support the hypothesis that Topo-II alpha amplification is the mechanism behind benefit from increased dose of anthracyclines in HER2-positive breast cancer.

AB Purpose Gleason grading is an important predictor of prostate cancer (PCa) outcomes. Studies using surrogate PCa end points suggest outcomes for Gleason score (GS) 7 cancers vary according to the predominance of pattern 4. These studies have influenced clinical practice, but it is unclear if rates of PCa mortality differ for 3 + 4 and 4 + 3 tumors. Using PCa mortality as the primary end point, we compared outcomes in Gleason 3 + 4 and 4 + 3 cancers, and the predictive ability of GS from a standardized review versus original scoring.
Patients and Methods Three study pathologists conducted a blinded standardized review of 693 prostatectomy and 119 biopsy specimens to assign primary and secondary Gleason patterns. Tumor specimens were from PCa patients diagnosed between 1984 and 2004 from the Physicians' Health Study and Health Professionals Follow-Up Study. Lethal PCa (n = 53) was defined as development of bony metastases or PCa death. Hazard ratios (HR) were estimated according to original GS and standardized GS. We compared the discrimination of standardized and original grading with C-statistics from models of 10-year survival.
Results For prostatectomy specimens, 4 + 3 cancers were associated with a three-fold increase in lethal PCa compared with 3 + 4 cancers (95% CI, 1.1 to 8.6). The discrimination of models of standardized scores from prostatectomy (C-statistic, 0.86) and biopsy (C-statistic, 0.85) were improved compared to models of original scores (prostatectomy C-statistic, 0.82; biopsy C-statistic, 0.72).
Conclusion Ignoring the predominance of Gleason pattern 4 in GS 7 cancers may conceal important prognostic information. A standardized review of GS can improve prediction of PCa survival.

AB Purpose
Patients with chronic myelogenous leukemia in accelerated phase (CML-AP) that is resistant or intolerant to imatinib have limited therapeutic options. Dasatinib, a potent inhibitor of BCR-ABL and SRC-family kinases, has efficacy in patients with CML-AP who have experienced treatment failure with imatinib. We now report follow-up data from the full patient cohort of 174 patients enrolled onto a phase II trial to provide a more complete assessment of the efficacy and safety of dasatinib in this population.
Patients and Methods
Patients with imatinib-resistant (n = 161) or -intolerant (n = 13) CML-AP received dasatinib 70 mg orally twice daily.
Results
At a median follow-up of 14.1 months (treatment duration, 0.1 to 21.7 months), major and complete hematologic responses were attained by 64% and 45% of patients, respectively, and major and complete cytogenetic responses were achieved in 39% and 32% of patients, respectively. Responses were achieved irrespective of imatinib status (resistant or intolerant), prior stem-cell transplantation, or the presence of prior BCR-ABL mutation. The 12-month progression-free survival and overall survival rates were 66% and 82%, respectively. Dasatinib was generally well tolerated; the most frequent nonhematologic severe treatment-related adverse event was diarrhea (52%; grade 3 to 4, 8%). Cytopenias were common, including grade 3 to 4 neutropenia (76%) and thrombocytopenia (82%). Pleural effusion occurred in 27% of patients (grade 3 to 4, 5%).
Conclusion
Dasatinib is effective in patients with CML-AP after imatinib treatment failure.

AB Purpose Primary CNS lymphoma (PCNSL) is confined to the CNS and/or the eyes at presentation and is usually initially treated with intravenous methotrexate-based chemotherapy and whole-brain radiotherapy (WBRT). However, the intact blood-brain barrier (BBB) can limit diffusion of methotrexate into brain and tumor. With BBB disruption (BBBD), enhanced drug delivery to the tumor can be achieved.
Patients and Methods This report summarizes the multi-institutional experience of 149 newly diagnosed (with no prior WBRT) patients with PCNSL treated with osmotic BBBD and intra-arterial (IA) methotrexate at four institutions from 1982 to 2005. In this series, 47.6% of patients were age >= 60 years, and 42.3% had Karnofsky performance score (KPS) less than 70 at diagnosis.
Results The overall response rate was 81.9% (57.8% complete; 24.2% partial). Median overall survival (OS) was 3.1 years (25% estimated survival at 8.5 years). Median progression-free survival (PFS) was 1.8 years, with 5-year PFS of 31% and 7-year PFS of 25%. In low-risk patients (age >= 60 years and KPS >= 70), median OS was approximately 14 years, with a plateau after approximately 8 years. Procedures were generally well tolerated; focal seizures (9.2%) were the most frequent side effect and lacked long-term sequelae.
Conclusion This large series of patients treated over a 23-year period demonstrates that BBBD/IA methotrexate-based chemotherapy results in successful and durable tumor control and outcomes that are comparable or superior to other PCNSL treatment regimens.

AB Purpose To assess efficacy and safety of single-agent bortezomib in previously untreated patients with multiple myeloma, investigate prevalence of baseline and treatment-emergent polyneuropathy, and identify molecular markers associated with response and neuropathy.
Patients and Methods Patients received bortezomib 1.3 mg/m(2) on days 1, 4, 8, and 11, for up to eight 21-day cycles. A subset of patients underwent neurophysiologic evaluation pre- and post-treatment. Bone marrow aspirates were performed at baseline for exploratory whole-genome analyses.
Results Among 64 patients, 41% had partial response or better, including 9% complete/near-complete responses; median duration of response was 8.4 months. Response rates did not differ in the presence or absence of adverse cytogenetics. After median follow-up of 29 months, median time to progression was 17.3 months. Median overall survival had not been reached; estimated 1-year survival was 92%. Thirty-two patients successfully underwent optional stem-cell transplantation. Bortezomib treatment was generally well tolerated. At baseline, 20% of patients had sensory polyneuropathy. Sensory polyneuropathy developed during treatment in 64% of patients ( grade 3 in 3%), but proved manageable and resolved in 85% within a median of 98 days. Neurologic examination, neurophysiologic testing, and measurements of epidermal nerve fiber densities in 35 patients confirmed pretreatment sensory neuropathy in 20% and new or worsening neuropathy in 63%. Pharmacogenomic analyses identified molecular markers of response and treatment-emergent neuropathy, which will require future study.
Conclusion Single-agent bortezomib is effective in previously untreated myeloma. Baseline myelomaassociated neuropathy seems more common than previously reported, and bortezomib-associated neuropathy, although a common toxicity, is reversible in most patients.

AB The use of coherent light in conventional holographic phase microscopy (HPM) poses three major drawbacks: poor spatial resolution, weak depth sectioning, and fixed pattern noise due to unwanted diffraction. Here, we report a technique which can overcome these drawbacks, but maintains the advantage of phase microscopy - high contrast live cell imaging and 3D imaging. A speckle beam of a complex spatial pattern is used for illumination to reduce fixed pattern noise and to improve optical sectioning capability. By recording of the electric field of speckle, we demonstrate high contrast 3D live cell imaging without the need for axial scanning - neither objective lens nor sample stage. This technique has great potential in studying biological samples with improved sensitivity, resolution and optical sectioning capability. (C) 2009 Optical Society of America

AB Macrophages in the central nervous system (CNS) and other tissues are an important cellular reservoir for human immunodeficiency virus type 1 (HIV) infection, particularly in the later stages of disease. Macrophage-tropic HIV strains have an enhanced capacity to enter cells expressing low levels of CD4 through mechanisms that are not well understood. Here, we use a panel of primary HIV envelopes from brain and lymphoid tissues to examine the relationship between neutralization sensitivity to reagents targeting the CD4 binding site and virus entry into macrophages. Neutralization assays using pseudotyped viruses showed an association between the capacity of HIV to enter macrophages and increased sensitivity to the broadly neutralizing monoclonal antibody (mAb) b12, which recognizes a conserved epitope overlapping the CD4 binding site, but not sensitivity to soluble CD4 (sCD4) or b6, a non-neutralizing CD4 binding site mAb. Furthermore, loss of an N-linked glycosylation site at position 386 in the V4 region of Env enhanced macrophage tropism together with b12 sensitivity, but not neutralization by sCD4, b6, or a broadly neutralizing AIDS patient serum. These findings suggest that exposure of the b12 epitope, rather than exposure of the CD4 binding site per se, enhances HIV macrophage tropism, possibly by exposing a region on the outer domain of gp120 that is initially recognized by CD4. These findings suggest overlap between specific gp120 determinants in or near the b12 epitope and those conferring macrophage tropism.

AB In this study we examined behavioral sleep in the walrus, the only living species of the family Odobenidae. The behavior of four 1.5-2-year-old captive walruses was videotaped continuously for 7-17 days and scored in 1-min epochs. When walruses had access to water and land, behavioral sleep, the combined amount of quiet and rapid eye movement (REM) sleep, occupied on average 17 +/- 4% of 24 h (n = 4) with the majority of sleep occurring on land. All walruses alternated periods of almost continuous swimming lasting for 40-84 h with periods of rest on land lasting for 2-19 h. When in water they were predominantly awake (88-99% of the time). On land walruses were asleep on average 40-74% of the time. The total sleep time varied between 0 and 60% of 24 h with the daily amount of REM sleep ranging from 0 to 5% of 24 h. In water, walruses slept while floating at the surface, lying on the bottom or standing and leaning against the pool wall. REM sleep in water occurred in all positions. On land the breathing pattern was regular during quiet sleep (most pauses were <30s) and arrhythmic in REM sleep (apneas lasted up to 160s). While in water the irregularity of breathing further increased (apneas were >4 min) and all REM sleep episodes occurred during a single apnea. Data indicate that the pattern of sleep and breathing in walruses is similar to the Otariidae seats while on land and the Phocidae seats while in water. Published by Elsevier B.V.

AB Background Turnout necrosis factor a (TNF alpha) inhibitors are frequently used to treat rheumatoid arthritis, but whether use of a different TNF alpha inhibitor can improve patient response is unknown. We assess the efficacy and safety of the TNF alpha inhibitor golimumab in patients with active rheumatoid arthritis who had previously received one or more TNF alpha inhibitors.
Methods 461 patients with active rheumatoid arthritis from 82 sites in 10 countries were randomly allocated by interactive voice response system, stratified by study site and methotrexate use, to receive subcutaneous injections of placebo (n=155), 50 mg golimumab (n=153), or 100 mg golimumab (n=153) every 4 weeks between Feb 21, 2006, and Sept 26, 2007. Allocation was double-blind. Eligible patients had been treated with at least one dose of a TNF alpha inhibitor previously. Patients continued stable doses of methotrexate, sulfasalazine, hydroxychloroquine, oral corticosteroids, and non-steroidal anti-inflammatory drugs. The primary endpoint was achievement at week 14 of 20% or higher improvement in American College of Rheumatology criteria for assessment of rheumatoid arthritis (ACR20). At week 16, patients who had less than 20% improvement in tender and swollen joint counts were given rescue therapy and changed treatment from placebo to 50 mg golimumab, or from 50 mg to 100 mg golimumab. Drug efficacy was assessed by intention to treat and safety was assessed according to the study drug given. This study is registered with ClinicalTrials.gov, number NCT00299546.
Findings Patients had discontinued previous TNF alpha inhibitors because of lack of effectiveness (269 [58%] patients) or reasons unrelated to effectiveness (246 [53%] patients), such as intolerance and accessibility issues. Patients had active disease, which was indicated by a median of 14.0 (IQR 9.0-22.0) swollen and 26.0 (16.0-41.0) tender joints for the whole group. 28 (18%) patients on placebo, 54 (35%) patients on 50 mg golimumab (odds ratio 2.5 [95% Cl 1.5-4.2], p=0.0006), and 58 (38%) patients on 100 mg golimumab (2.8 [1.6-4.7], p=0.0001) achieved ACR20 at week 14. Two patients were never treated, and 57 patients did not complete the study because of adverse events, unsatisfactory treatment effect, loss to follow-up, death, or other reasons. 155 patients on placebo, 153 on 50 mg golimumab, and 153 on 100 mg golimumab were assessed for drug efficacy. For weeks 1-16, serious adverse events were recorded in 11 (7%) patients on placebo, 8 (5%) on 50 mg golimumab, and 4 (3%) on 100 mg golimumab. For weeks 1-24, after some patients were given rescue therapy, serious adverse events were recorded in 15 (10%) patients on placebo, 14 (5%) on 50 mg golimumab, and 8 (4%) on 100 mg golimumab.
Interpretation Golimumab reduced the signs and symptoms of rheumatoid arthritis in patients with active disease who had previously received one or more TNF alpha inhibitors.

AB Bladder cancer is a heterogeneous disease, with 70% of patients presenting with superficial tumours, which tend to recur but are generally not life threatening, and 30% presenting as muscle-invasive disease associated with a high risk of death from distant metastases. The main presenting symptom of all bladder cancers is painless haematuria, and the diagnosis is established by urinary cytology and transurethral tumour resection. Intravesical treatment is used for carcinoma in situ and other high grade non-muscle-invasive tumours. The standard of care for muscle-invasive disease is radical cystoprostatectomy, and several types of urinary diversions are offered to patients, with quality of life as an important consideration. Bladder preservation with transurethral tumour resection, radiation, and chemotherapy can in some cases be equally curative. Several chemotherapeutic agents have proven to tie useful as neoadjuvant or adjuvant treatment and in patients with metastatic disease. We discuss bladder preserving approaches, combination chemotherapy including new agents, targeted therapies, and advances in molecular biology.

AB Objective: To determine the effects of switching from lopinavir/ritonavir (LPV/r) to atazanavir/ritonavir (ATV/r) on muscle glucose uptake, glucose homeostasis, lipids, and body composition.
Methods: Fifteen HIV-infected men and women on a regimen containing LPV/r and with evidence of hyperinsulinemia and/or dyslipidemia were randomized to continue LPV/r or to switch to ATV/r (ATV 300 mg and ritonavir 100 mg daily) for 6 months. The primary endpoint was change in thigh muscle glucose uptake as measured by positron emission tomography. Secondary endpoints included abdominal visceral adipose tissue, fasting lipids, and safety parameters. The difference over time between treatment groups (treatment effect of ATV/r relative to LPV/r) was determined by repeated measures ANCOVA.
Results: After 6 months, anterior thigh muscle glucose uptake increased significantly (treatment effect +18.2 +/- 5.9 mu mol/kg per min, ATV/r vs. LPV/r, P=0.035), and visceral adipose tissue area decreased significantly in individuals who switched to ATV/r (treatment effect -31 +/- 11 cm(2), ATV/r vs. LPV/r, P=0.047). Switching to ATV/r significantly decreased triglyceride (treatment effect -182 +/- 64 mg/dl, ATV/r vs. LPV/r, P=0.02) and total cholesterol (treatment effect -23 +/- 8 mg/dl, ATV/r vs. LPV/r, P=0.01), whereas high-density lipoprotein and low-density lipoprotein did not change significantly. Fasting glucose also decreased significantly following switch to ATV/r (treatment effect -15 +/- 4 mg/dl, ATV/r vs. LPV/r, P=0.002).
Conclusion: Switching from LPV/r to ATV/r significantly increases glucose uptake by muscle, decreases abdominal visceral adipose tissue, improves lipid parameters, and decreases fasting glucose over 6 months. (C) 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins

AB Recent studies have demonstrated that kynurenic acid (KYNA), a compound produced endogenously by the interferon-gamma-induced degradation of tryptophan by indoleamine 2,3-dioxygenase, activates the previously orphaned G protein-coupled receptor, GPR35. This receptor is expressed in immune tissues, although its potential function in immunomodulation remains to be explored. We determined that GPR35 was most highly expressed on human peripheral monocytes. In an in vitro vascular flow model, KYNA triggered the firm arrest of monocytes to both fibronectin and ICAM-1, via beta(1) integrin- and beta(2) integrin-mediated mechanisms, respectively. Incubation of monocytes with pertussis toxin prior to use in flow experiments significantly reduced the KYNA-induced monocyte adhesion, suggesting that adhesion is triggered by a G(i)-mediated process. Furthermore, KYNA-triggered adhesion of monocytic cells was reduced by short hairpin RNA-mediated silencing of GPR35. Although GPR35 is expressed at slightly lower levels on neutrophils, KYNA induced firm adhesion of these cells to an ICAM-1-expressing monolayer as well. KYNA also elicited neutrophil shedding of surface L-selectin, another indicator of leukocyte activation. Taken together, these data suggest that KYNA could be an important early mediator of leukocyte recruitment.

AB Parkinson's disease (PD) is the second most common form of human degenerative disorder. Mutation of parkin is one of the most prevalent causes of autosomal recessive PD. Parkin is an E3 ubiquitin ligase that acts on a variety of substrates, resulting in polyubiquitination and degradation by the proteasome or monoubiquitination and regulation of biological activity. However, the cellular functions of parkin that relate to its pathological involvement in PD are not well understood. Here I show that parkin translocates into nucleus upon DNA damage. Nuclear translocation of parkin appears to be required to promote DNA repair. These findings suggest that DNA damage induces nuclear translocation of parkin leading to the PCNA interaction and possibly other nuclear proteins involved in DNA repair. These results suggest that parkin promotes DNA repair and protects against genotoxicity, and implicate DNA damage as a potential pathogenic mechanism in parkinsonism.

AB Acute graft-versus-host disease (aGVHD) is the primary limitation of allogeneic hematopoietic cell transplantation. Corticosteroids remain the standard initial therapy, yet only 25% to 41% of patients completely respond. This randomized, 4-arm, phase 2 trial was designed to identify the most promising agent(s) for initial therapy for aGVHD. Patients were randomized to receive methylprednisolone 2 mg/kg per day plus etanercept, mycophenolate mofetil (MMF), denileukin diftitox (denileukin), or pentostatin. Patients (n = 180) were randomized; their median age was 50 years (range, 7.5-70 years). Myeloablative conditioning represented 66% of transplants. Grafts were peripheral blood (61%), bone marrow (25%), or umbilical cord blood (14%); 53% were from unrelated donors. Patients who received MMF for prophylaxis (24%) were randomized to a non-MMF arm. At randomization, aGVHD was grade I to II (68%), III to IV (32%), and (53%) had visceral organ involvement. Day 28 complete response rates were etanercept 26%, MMF 60%, denileukin 53%, and pentostatin 38%. Corresponding 9-month overall survival was 47%, 64%, 49%, and 47%, respectively. Cumulative incidences of severe infections were as follows: etanercept 48%, MMF 44%, denileukin 62%, and pentostatin 57%. Efficacy and toxicity data suggest the use of MMF plus corticosteroids is the most promising regimen to compare against corticosteroids alone in a definitive phase 3 trial. This study is registered at http://www. clinicaltrials.gov as NCT00224874. (Blood. 2009; 114: 511-517)

AB The interaction of multiple myeloma (MM) cells with the bone marrow (BM) milieu plays a crucial role in MM pathogenesis. Stromal cell-derived factor-1 (SDF1) regulates homing of MM cells to the BM. In this study, we examined the role of RhoA and Rac1 GTPases in SDF1-induced adhesion and chemotaxis of MM. We found that both RhoA and Rac1 play key roles in SDF1-induced adhesion of MM cells to BM stromal cells, whereas RhoA was involved in chemotaxis and motility. Furthermore, both ROCK and Rac1 inhibitors reduced SDF1-induced polymerization of actin and activation of LIMK, SRC, FAK, and cofilin. Moreover, RhoA and Rac1 reduced homing of MM cells to BM niches. In conclusion, we characterized the role of RhoA and Rac1 GTPases in SDF1-induced adhesion, chemotaxis, and homing of MM cells to the BM, providing the framework for targeting RhoA and Rac1 GTPases as novel MM therapy.

AB To more comprehensively assess the pathogenic contribution of the PTEN-PI3K-AKT pathway to T-cell acute lymphoblastic leukemia (T-ALL), we examined diagnostic DNA samples from children with T-ALL using array comparative genomic hybridization and sequence analysis. Alterations of PTEN, PI3K, or AKT were identified in 47.7% of 44 cases. There was a striking clustering of PTEN mutations in exon 7 in 12 cases, all of which were predicted to truncate the C2 domain without disrupting the phosphatase domain of PTEN. Induction chemotherapy failed to induce remission in 3 of the 4 patients whose lymphoblasts harbored PTEN deletions at the time of diagnosis, compared with none of the 12 patients with mutations of PTEN exon 7 (P = .007), suggesting that PTEN deletion has more adverse therapeutic consequences than mutational disruptions that preserve the phosphatase domain. These findings add significant support to the rationale for the development of therapies targeting the PTEN-PI3K-AKT pathway in T-ALL. (Blood. 2009; 114: 647-650)

ID CARDIAC TROPONIN; MYOCARDIAL-INFARCTION; MORTALITY; RISK; TERM
AB We aimed to elucidate the clinical significance of borderline troponin I (TnI) increases and see if such increases are of similar significance across different assays. Markedly increased TnI is a strong predictor of adverse cardiac events. It is not clear if borderline increases with different commercially available TnI assays provide similar prognostic information. From January 2001 to February 2004, 3 different TnI assays (Beckman Access TnI, Beckman Access AccuTnI, and Vitros ECI Troponin) were used to evaluate the peak TO value in 1,152 consecutive patients admitted with suspected acute coronary syndrome/non-ST-elevation myocardial infarction (MI). Recommended cutoffs were used to differentiate borderline from marked increases reported as consistent with MI. Clinical data and 30-day death/new MIs were determined by chart abstraction. Demographics and cardiac risk factors were similar for the 3 groups. Frequency of borderline TnI ranged widely among assays (18.7% to 42.1%) but was significantly less with the Vitros ECI Troponin assay (p < 0.0001). Prognostic significance of borderline increased TnI values also varied greatly by assay, with borderline Beckman Access AccuTnI increases being predictive of adverse 30-day outcomes (odds ratio 4.0, 95% confidence interval 1.46 to 10.97, p = 0.007), but not with the other 2 assays. Borderline increases were significantly associated with chronic renal insufficiency (CRI; serum creatine > 1.5); the relation to adverse 30-day outcomes and borderline increases persisted after correcting for CRI in a multivariate logistic regression model. In conclusion, although borderline increased TnI levels are common and significantly associated with CRI, they do not all portend the same clinical prognosis. This study highlights the need for standardization of TnI levels across different assays. (C) 2009 Published by Elsevier Inc. (Am J Cardiol 2009;104:164-168)

AB Use of evidence-based medicine (EBM) improves outcomes after acute coronary syndromes (ACS), yet patients often discontinue prescribed therapies after discharge. Although such discontinuation is well documented, patients' reasons for medication discontinuation have not been reported. MAINTAIN is a longitudinal follow-up registry of CRUSADE/ACTION, which enrolled patients during an ACS hospitalization from January 2006 to September 2007. All discharge medications were obtained from hospital charts. Patients were interviewed by telephone 3 months after discharge to determine if EBM classes prescribed at discharge were continued (aspirin, clopidogrel, beta blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and lipid-lowering medications). If discontinuation occurred, patients were asked if it was with provider knowledge/input or not (self-discontinuation). A multivariable logistic regression model was performed to identify factors associated with self-discontinuation of prescribed EBM. Of the 1,077 patients interviewed, 1,006 (93.4%) were discharged on aspirin, 816 (75.8%) on clopidogrel, 982 (91.2%) on beta blockers, 745 (69.2%) on angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and 968 (89.9%) on lipid-lowering medications. At 3-month follow-up, 304 patients (28.2%) had discontinued >= 1 of these prescribed EBM classes. Although many reported provider involvement, most discontinuation (61.5%) was self-determined. Factors independently associated with self-discontinuation were no pharmacy coinsurance, increasing number of medications, not using reminder tools (e.g., pillbox), lower education, and dialysis. In conclusion, 1/3 of patients with ACS discontinue >= 1 of their prescribed EBMs within 3 months of hospital discharge, and most of this discontinuation is without provider involvement. Patient education, better prescription drug coverage, and reminder strategies may improve use of EBMs at 3 months after discharge from ACS admission. (C) 2009 Published by Elsevier Inc.

AB Previous clinical trials have shown that alpha(1)-adrenergic antagonists are not effective in subjects with heart failure (HF) and might increase HF rates when used for hypertension. However, alpha(1)-adrenergic antagonists may be prescribed to subjects with HF who have symptomatic benign prostatic hyperplasia. We sought to determine any association between alpha(1)-adrenergic antagonist use, commonly prescribed for benign prostatic hyperplasia, and the clinical outcomes of subjects with HF receiving contemporary therapy. An existing database of 388 subjects with decompensated HF admissions from 2002 to 2004 at the Veterans Affairs Hospital was analyzed according to the use of alpha(1)-adrenergic antagonists at discharge. Covariate-adjusted Cox proportional hazard models were used to examine any association with future admissions for decompensated HF and total mortality. Alpha-1-adrenergic antagonist therapy was prescribed in 25% of our HF population, predominantly for benign prostatic hyperplasia, and was not associated with significant increases in the combined risk of all-cause mortality and rehospitalization for HF (hazard ratio 1.24, 95% confidence interval 0.93 to 1.65, p = 0.14), HF hospitalization (hazard ratio 1.20, 95% confidence interval 0.85 to 1.70, p 0.31), or all-cause mortality (hazard ratio 1.10, 95% confidence interval 0.78 to 1.56, p 0.57). In patients not receiving beta-blocker therapy, alpha(1)-adrenergic antagonist therapy was significantly associated with increased HF hospitalizations (hazard ratio 1.94, 95% confidence interval 1.14 to 3.32, p = 0.015). In conclusion, in patients with chronic HF, the use of alpha(1)-adrenergic antagonists was significantly associated with more HF hospitalizations when prescribed without concomitant beta blockade. Thus, background beta-blocker therapy appears to be protective against the potential harmful effects of alpha(1)-adrenergic antagonist therapy in patients with HF. Published by Elsevier Inc.

TRIAL; DISEASE; DIAGNOSIS; SUBTYPES; TIME
AB Acute-phase levels of B-type natriuretic peptide (BNP) and the N-terminal fragment of the BNP prohormone (NT-pro-BNP) have been associated with mortality when measured in patients with an acute ischemic stroke; however, data regarding the longer-term value of NT-pro-BNP for long-term prognostication after ischemic stroke are limited. Two hundred sixteen patients (mean age 67 +/- 13 years) with acute ischemic stroke were seen 6 months after index admission at which time a structured evaluation including measurement of plasma NT-pro-BNP was performed. Patients were followed for 45 months, with all-cause mortality as the clinical end point. Median NT-pro-BNP concentration for the entire group was 147 pg/ml (10th to 90th percentiles 37 to 869). At follow-up 45 patients (21%) had died. NT-pro-BNP concentrations were significantly higher in decedents (308 pg/ml, 10th to 90th percentiles 74 to 2,279) than in the 171 survivors (132 pg/ml, 10th to 90th percentiles 35 to 570, p < 0.001). Patients with NT-pro-BNP <= 147 pg/ml had a significantly improved survival rate on univariate analysis (p < 0.001). In multivariate analysis after adjustment for age, stroke severity, heart and renal failures, levels of NT-pro-BNP were an independent predictor of mortality > 6 months after stroke (adjusted hazard ratio 1.5, 95% confidence interval 1.1 to 1.9, p = 0.005). In conclusion, NT-pro-BNP concentrations measured during the stable phase after acute ischemic stroke are strongly predictive of long-term mortality. (C) 2009 Elsevier Inc.

ID INTRAVENOUS ACYCLOVIR; NEPHROTOXICITY
AB Purpose. A case of acyclovir-induced acute renal failure in an obese patient is described.
Summary. A 60-year-old white man arrived at the emergency department complaining of confusion and disorientation. He was 5 ft 7 in tall and weighed 108.9 kg. His medical and surgical histories included chronic obstructive pulmonary disease (COPD), sleep apnea not requiring biphasic positive airway pressure, obesity, oxygen supplementation, and appendectomy. He also had a history of cyst drainage on the back of his neck, with recent drainage emitting a foul odor, and suffered recurrent herpes cold sores on his chin. A lumbar puncture revealed abnormal cerebral spinal fluid. A diagnosis of herpes encephalitis was considered, and the patient was empirically treated with i.v. acyclovir 1 g over 60 minutes every eight hours, with the dosage based on actual body weight. He was also given moxifloxacin 400 mg i.v. daily for possible COPD exacerbation and doxycycline 100 mg i.v. twice daily for possible leptospirosis meningitis. On hospital day 3, his serum creatinine (SCr) and blood urea nitrogen (BUN) concentrations rose to 2.8 g/dL and 32 mg/dL, respectively. Acyclovir was subsequently discontinued, as were all i.v. antibiotics. On day 7, hydration therapy was initiated, as was therapy to alkalinize the urine, and his neurologic status began to improve. At discharge, the patient's SCr and BUN levels were 3.1 g/dL and 38 mg/dL, respectively. His discharge diagnoses included encephalitis with possible viral origin and acyclovir-induced nephrotoxicity.
Conclusion. An obese man receiving excessive doses of i.v. acyclovir developed acute but reversible renal failure.

longitudinal survey
ID IMPAIRMENT; DEFICITS; COPD
AB Rationale: Prior research has suggested an association between chronic obstructive pulmonary disease (COPD) and the development of cognitive decline; however, these studies have been cross-sectional or small case series.
Objectives: To determine whether COPD increases the risk of cognitive decline among older adults surveyed in a large, population-based longitudinal cohort.
Methods: We included data from the 1996 to 2002 waves of the Health and Retirement Study, a biennial nationally representative survey. We studied respondents who completed cognitive testing in 1996 and at least one subsequent survey, and excluded those with unknown history of COPD. Clinical history of COPD was based on self-report; severity was categorized based on use of oxygen or disease-related activity limitations. Our primary outcome was cognitive performance, measured using a validated 35-point scale. We examined the effect of COPD on cognition using multivariable mixed linear models accounting for repeated measurements, adjusted for sociodemographic and clinical characteristics.
Measurements and Main Results: A total of 4,150 adults were included in our study. Among them, 12% reported a history of COPD (29% severe, 71% nonsevere disease). On repeated measurement, mean cognition scores of older adults with both severe and nonsevere COPD were significantly lower when compared with adults without COPD (2.6 points [P < 0.001] and 0.9 points [P < 0,001], respectively). After multivariable adjustment, mean scores of adults with severe COPD remained lower (0.9 point [P < 0.001]), whereas mean score of adults with nonsevere COPD was no longer different (P = 0.39) when compared with adults without COPD.
Conclusions. Severe COPD was associated with lower cognitive performance on standardized measurement over time.

AB Abnormal adenosine to inosine (A-to-1) messenger RNA (mRNA) editing has been linked to several disease states afflicting the central nervous system. Here we report an assay to determine RNA editing frequencies at specific sites that is based on quantitative polymerase chain reaction (qPCR) with TaqMan probes. The assay was tested by measuring the frequency of the A-to-1 mRNA editing at the Q/R site of the human kainate receptor Subunit GluR5 and was compared with two established methods of assessing RNA editing: sequencing of individual clones and restriction analysis. The qPCR assay displayed high sensitivity and reproducibility, demonstrated exceptional discrimination between edited and Unedited transcript variants, and proved to have several advantages over the other editing methods. Due to the fact that TaqMan-based qPCR technology can be easily adapted to different editing targets, the increased capabilities afforded by this new technique should facilitate various RNA editing studies that aim to elucidate the role of this process in normal physiology and in disease.

AB Biopsies provide required information to diagnose cancer but, because of their invasiveness, they are difficult to use for managing cancer therapy. The ability to repeatedly sample the local environment for tumor biomarker, chemotherapeutic agent, and tumor metabolite concentrations could improve early detection of metastasis and personalized therapy. Here we describe an implantable diagnostic device that senses the local in vivo environment. This device, which could be left behind during biopsy, uses a semi-permeable membrane to contain nanoparticle magnetic relaxation switches. A cell line secreting a model cancer biomarker produced ectopic tumors in mice. The transverse relaxation time (T(2)) of devices in tumor-bearing mice was 20 +/- 10% lower than devices in control mice after 1 day by magnetic resonance imaging (p < 0.01). Short term applications for this device are numerous, including verification of successful tumor resection. This may represent the first continuous monitoring device for soluble cancer biomarkers; in vivo. (C) 2009 Elsevier B.V. All rights reserved.

AB Background: The widespread use of tissue plasminogen activator (tPA), the only FDA-approved acute stroke treatment, remains limited by its narrow therapeutic time window and related risks of brain hemorrhage. Normobaric oxygen therapy (NBO) may be a useful physiological strategy that slows down the process of cerebral infarction, thus potentially allowing for delayed or more effective thrombolysis. In this study we investigated the effects of NBO started simultaneously with intravenous tPA, in spontaneously hypertensive rats subjected to embolic middle cerebral artery (MCA) stroke. After homologous clot injection, animals were randomized into different treatment groups: saline injected at 1 hour; tPA at 1 hour; saline at 1 hour plus NBO; tPA at 1 hour plus NBO. NBO was maintained for 3 hours. Infarct volume, brain swelling and hemorrhagic transformation were quantified at 24 hours. Outcome assessments were blinded to therapy.
Results: Upon clot injection, cerebral perfusion in the MCA territory dropped below 20% of pre-ischemic baselines. Both tPA-treated groups showed effective thrombolysis (perfusion restored to nearly 100%) and smaller infarct volumes (379 +/- 57 mm(3) saline controls; 309 +/- 58 mm(3) NBO; 201 +/- 78 mm(3) tPA; 138 +/- 30 mm(3) tPA plus NBO), showing that tPA-induced reperfusion salvages ischemic tissue and that NBO does not significantly alter this neuroprotective effect. NBO had no significant effect on hemorrhagic conversion, brain swelling, or mortality.
Conclusion: NBO can be safely co-administered with tPA. The efficacy of tPA thrombolysis is not affected and there is no induction of brain hemorrhage or edema. These experimental results require clinical confirmation.

AB BACKGROUND: Nonalcoholic steatohepatitis (NASH) is a form of liver damage that can progress to cirrhosis. NASH is associated with obesity and diabetes. The condition also may be associated with some medications, including tamoxifen. Early case reports and small series have documented NASH in patients who received tamoxifen. METHODS: The records of patients registered in the St. Vincent Hospital Cancer Registry of Green Bay Wisconsin from January 1, 1992 to December 31, 2000 were reviewed. RESULTS: In total, 1105 patients with breast cancer were evaluated for NASH, and 24 cases of NASH were documented (2.2%). Seven patients had NASH before their diagnosis of breast cancer, and 17 patients developed NASH after their diagnosis of breast cancer. In multivariate analysis, the factors associated with NASH were tamoxifen use (odds ratio [OR], 8.2; 95% confidence interval [CI], 1.06-63.72), body mass index (BMI) (OR, 1.13; 95% CI, 1.06-1.20), and age (OR, 95% CI, 0.91-0.99). NASH improved after tamoxifen was stopped. After discontinuation of tamoxifen, transaminase levels returned to normal in 14 of 16 patients. CONCLUSIONS: NASH was present in 24 of 1105 patients with breast cancer (2.2%). Seven patients had NASH before they were diagnosed with breast cancer, and 17 patients developed NASH after their diagnosis. NASH was associated with the use of tamoxifen and improved when tamoxifen was stopped. Cancer 2009;115:3189-95. (C) 2009 American Cancer Society.

AB BACKGROUND: Cancer patients with limited English proficiency may need specialized assistance to communicate with health professionals about cancer and clinical trials. METHODS: Medical interpreters working in several Boston-area hospitals were invited to participate in training sessions about cancer and cancer clinical trials. We did a pre and post survey-based assessment of knowledge of basic concepts in cancer and clinical trials, and post assessment of satisfaction, among 97 interpreters in cancer training and education sessions and 79 participants in clinical trial training and education sessions. RESULTS: Participants had a range of prior experience with interpretation in the context of cancer and clinical trials. Training increased mean accuracy from 49% to 72% in knowledge items about cancer, and from 72% to 78% in knowledge about clinical trials. Interpreters reported several areas of concern with respect to standards of practice. CONCLUSIONS: Pretest surveys of medical interpreters revealed several areas of important knowledge gaps about cancer and clinical trials. Posttest assessment showed that training can be useful to improving short-term accuracy, but that more work is needed to develop curricula and testing measures to address these knowledge gaps.

AB BACKGROUND: Patients consider their human connection with a physician an important aspect of end-of-life (EOL) care. In this study, the authors sought to develop and validate a measure of therapeutic alliance between patients with advanced cancer and their physicians and to evaluate the effects of therapeutic alliance on EOL experiences and care. METHODS: The Human Connection (THC) scale was developed to measure the extent to which patients felt a sense of mutual understanding, caring, and trust with their physicians. The scale was administered to 217 patients with advanced cancer along with measures of attributes that have been related hypothetically to therapeutic alliance, including emotional acceptance of terminal illness. EOL outcomes in 90 patients who died during the study also were examined. RESULTS: The 16-item THC questionnaire was consistent internally (Cronbach alpha = .90) and valid based on its expected positive association with emotional acceptance of terminal illness (r = .31; P < .0001). THC scores were related inversely to symptom burden (r = -.19; P = .006), functional status (Karnofsky performance status; r = .22; P = .001), and mental illness (THC score: 50.69 for patients with any Diagnostic and Statistical Manual [DSM] diagnosis vs 55.22 for patients with no DSM diagnosis; P = .03). THC scores were not associated significantly with EOL discussions (P = .68). Among the patients who died, EOL intensive care unit (ICU) care was associated inversely with therapeutic alliance (THC score: 46.5 for patients who received ICU care vs 55.5 for patients without ICU care; P = .002), so that patients with higher THC scores were less likely to spend time in the ICU during the last week of life. CONCLUSIONS: The THC scale is a valid and reliable measure of therapeutic alliance between patients with advanced cancer and their physicians. In addition, there was no evidence to suggest that EOL discussions harm patients' therapeutic alliance. A strong therapeutic alliance was associated with emotional acceptance of a terminal illness and with decreased ICU care at the EOL among patients with advanced cancer. Cancer 2009;115:3302-11.

AB Solid tumors generate a prothrombotic environment capable of platelet activation. Recent findings indicate that the activated platelets are crucial regulators of tumor vascular homeostasis in that they prevent tumor hemorrhage. Surprisingly, this effect is independent of platelets' capacity to form thrombi and instead relies on the secretion of their granule content. Thus, targeting platelet secretory activities may represent a new approach to specifically destabilize tumor vasculature. [Cancer Res 2009;69(14):5623-6]

AB Inherited BRCA1/2 mutations confer elevated ovarian cancer risk. Knowledge of factors that can improve ovarian cancer risk assessment in BRCA1/2 mutation carriers is important because no effective early detection for ovarian cancers exists. A cohort of 1,575 BRCA1 and 856 BRCA2 mutation carriers was used to evaluate haplotypes at ATM, BARD1, BRIP1, CTIP, MRE11, NBS1, RAD50, RAD51, and TOPBP1 in ovarian cancer risk. In BRCA1 carriers, no associations were observed with ATM, BARD1, CTIP, RAD50, RAD51, or TOPBP1. At BRIP1, an association was observed for one haplotype with a multiple testing corrected P (P(corr)) = 0.012, although no individual haplotype was significant. At MRE11, statistically significant associations were observed for one haplotype (P(corr) = 0.007). At NBS1, we observed a P(corr) = 0.024 for haplotypes. In BRCA2 carriers, no associations were observed with CTIP, NBS1, RAD50, or TOPBP1. Rare haplotypes at ATM (P(corr) = 0.044) and BARD1 (P(corr) = 0.012) were associated with ovarian cancer risk. At BNP1, two common haplotypes were significantly associated with ovarian cancer risk (P(corr) = 0.011). At MRE11, we observed a significant haplotype association (P(corr) = 0.012). and at RAD51, one common haplotype was significantly associated with ovarian cancer risk (P(corr) = 0.026). Variants in genes that interact biologically with BRCA1 and/or BRCA2 may be associated with modified ovarian cancer risk in women who carry BRCA1/2 mutations. [Cancer Res 2009;69(14):5801-10]

Here, we tested the anti-MM activity of NVP-BEZ235 (BEZ235), which inhibits PI3K/Akt/mTOR signaling at the levels of PI3K and mTOR. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide colorimetric survival assays showed that MM cell lines exhibited dose- and time-dependent decreased viability after exposure to BEZ235 (IC(50), 25-800 nmol/L or 48 hours). MM cells highly sensitive (IC(50), <25 nmol/L) to BEZ235 (e.g., MM.1S, MM.1R, Dox40, and KMS-12-PE) included both lines sensitive and resistant to conventional (dexamethasone, cytotoxic chemotherapeutics) agents. Pharmacologically relevant BEZ235 concentrations (25-400 nmol/L,) induced rapid commitment to and induction of MM.1S and OPM-2 cell death. Furthermore, normal donor peripheral blood mononuclear cells were less sensitive (IC(50), >800 nmol/L) than the majority of MM cell lines tested, suggesting a favorable therapeutic index. In addition, BEZ235 was able to target MM cells in the presence of exogenous interleukin-6, insulin-like growth factor-1, stromal cells, or osteoclasts, which are known to protect against various anti-MM agents. Molecular profiling revealed that BEZ235 treatment decreased the amplitude of transcriptional signatures previously associated with myc, ribosome, and proteasome function, as well as high-risk MM and undifferentiated human embryonic stem cells. In vivo xenograft studies revealed significant reduction in tumor burden (P = 0.011) and survival (P = 0.028) in BEZ235-treated human MM tumor-bearing mice. Combinations of BEZ235 with conventional (e.g., dexamethasone and doxorubicin) or novel (e.g., bortezomib) anti-MM agents showed lack of antagonism. These results indicate that BEZ235 merits clinical testing, alone and in combination with other agents, in MM. [Cancer Res 2009;69(14):5835-42]

AB Despite their ability to cause septic shock and myocardial dysfunction, components of Gram-negative bacterial cell walls, like lipopolysaccharide, have been shown in numerous studies to induce myocardial protection during ischaemia-reperfusion injury. Muramyl dipeptide (MDP) is another such component recognized by an intracellular receptor, nucleotide-binding oligomerization domain 2. Receptor activation leads to intracellular signals through receptor interacting protein-2 (RIP2) and tumour growth factor-beta-activated kinase-1 (TAK1). However, little is known about the RIP2/TAK1 pathway in the heart. The aim of this study was to determine whether the RIP2/TAK1 pathway has a cardioprotective role in a mouse model of myocardial infarction.
We isolated and subjected wild-type (WT) and RIP2(-/-) mouse hearts to 30 min of global ischaemia and 120 min of reperfusion with or without perfusion of MDP (10 mu g/mL) before or after the ischaemic period and determined the infarct size. We examined activation of the TAK1/nuclear factor kappa B (NF kappa B) signalling pathway. The effect of TAK1 inhibition on MDP-induced cardioprotection was also evaluated. Exposure to MDP during reperfusion significantly reduced infarct size in WT hearts (from 51.7 +/- 5.6% in control to 38.1 +/- 6.7%, P < 0.05), but not in RIP2(-/-) hearts or in WT hearts with coincident pharmacological inhibition of TAK1. MDP treatment significantly increased the levels of p-TAK1 and p-JNK (Jun N-terminal kinase) and led to NF kappa B activation via phosphorylation and degradation of IkappaB in the WT, but not in the RIP2(-/-), myocardium.
These results indicate that MDP at reperfusion induced cardioprotection through an RIP2/TAK1-dependent mechanism.

TI MSH6 Mutations Arise in Glioblastomas during Temozolomide Therapy and

AB Purpose: Over the past few years, the alkylating agent temozolomide has become the standard-of-care therapy for patients with glioblastoma, the most common brain tumor. Recently, large-scale cancer genome sequencing efforts have identified a hypermutation phenotype and inactivating MSH6 mismatch repair gene mutations in recurrent, post-temozolomide glioblastomas, particularly those growing more rapidly during temozolomide treatment. This study aimed to clarify the timing and role of MSH6 mutations in mediating glioblastoma temozolomide resistance.
Experimental Design: MSH6 sequence and microsatellite instability (MSI) status were determined in matched prechemotherapy and postchemotherapy glioblastomas identified by The Cancer Genome Atlas (TCGA) as having posttreatment MSH6 mutations. Temozolomide-resistant lines were derived in vitro through selective growth under temozolomide, and the MSH6 gene was sequenced in resistant clones. The role of MSH6 inactivation in mediating resistance was explored using lentiviral short hairpin RNA knockdown and MSH6 reconstitution.
Results: MSH6 mutations were confirmed in posttreatment TCGA glioblastomas but absent in matched pretreatment tumors. The posttreatment hypermutation phenotype displayed a signature bias toward CpC transitions and was not associated with MSI. In vitro modeling through exposure of an MSH6 wild-type glioblastoma line to temozolomide resulted in resistant clones; one clone showed an MSH6 mutation,Thr(1219)lle, that had been independently noted in two treated TCGA glioblastomas. Knockdown of MSH6 in the glioblastoma line U251 increased resistance to temozolomide cytotoxicity and reconstitution restored cytotoxicity in MSH6-null glioma cells.
Conclusions: MSH6 mutations are selected in glioblastomas during temozolomide therapy both in vitro and in vivo and are causally associated with temozolomide resistance.

AB Purpose: The homeodomain transcription factor CDX2 is a relatively specific immunchistochemical marker for gastrointestinal carcinoma. However, no study has comprehensively examined the relationship between CDX2 expression in colon cancer and clinical, pathologic, prognostic, and molecular features, including microsatellite instability and CpG island methylator phenotype (CIMP).
Experimental Design: Utilizing 621 colorectal cancers with clinical outcome and molecular data, CDX2 loss was detected in 183 (29%) tumors by immunohistochemistry.
Results: In multivariate logistic regression analysis, CDX2 loss was associated with female gender [odds ratio (OR), 3.32; P < 0.0001], CIMP-high (OR, 4.42; P = 0.0003), high tumor grade (OR, 2.69; P = 0.0085), stage IV disease (OR, 2.03; P = 0.019), and inversely with LINE-1 hypomethylation (for a 30% decline; OR, 0.33; P = 0.0031), p53 expression (OR, 0.55; P = 0.011), and beta-catenin activation (OR, 0.60; P = 0.037), but not with body mass index, tumor location, microsatellite instability, BRAF, KRAS, PIK3CA, p21, or cyclooxygenase-2. CDX2 loss was not independently associated with patient survival. However, the prognostic effect of CDX2 loss seemed to differ according to family history of colorectal cancer (P-interaction = 0.0094). CDX2 loss was associated with high overall mortality (multivariate hazard ratio, 2.40; 95% Cl, 1.28-4.51) among patients with a family history of colorectal cancer; no such association was present (multivariate hazard ratio, 0.97; 95% Cl, 0.66-1.41) among patients without a family history of colorectal cancer.
Conclusions: CDX2 loss in colorectal cancer is independently associated with female gender, CIMP-high, high-level LINE-1 methylation, high tumor grade, and advanced stage. CDX2 loss may be associated with poor prognosis among patients with a family history of colorectal cancer.

AB Purpose: Vascular endothelial growth factor (VEGF) promotes angiogenesis and vascular permeability. The VEGF gene is polymorphic. We investigated the prognostic significance of three VEGF single nucleotide polymorphisms (SNP) in esophageal cancer.
Experimental Design: Three hundred sixty-one patients were genotyped for three VEGF SNPs (-460T/C, 405G/C, and 936C/T) using DNA extracted from prospectively collected blood samples. The association of each individual SNP, and haplotypes of the three SNPs, on overall survival (OS) was investigated.
Results: The variant allele of 936C/T was associated with improved OS compared with the wildtype genotype (log-rank P < 0.001). This association remained significant for OS after adjustments for age, gender, performance status, and disease stage [VEGF 936C/T: adjusted hazard ratio (AHR), 0.70; 95% confidence interval (95% CI), 0.49-0.99; P = 0.04; VEGF 936T/T: AHR, 0.11; 95% Cl, 0.02-0.82; P = 0.03]. No independent associations were found for VEGF -460T/C and VEGF 405G/C. The CGC haplotype of the three VEGF SNPs (-460T/C, 405G/C, and 936C/T) combined was associated with reduced OS compared with all other patients (CGC/CGC: AHR, 1.51; 95% Cl, 1.00-2.30; P = 0.05).
Conclusions: VEGF 936C/T, and a haplotype of 460T/C, 405G/C, and 936C/T combined, has potential prognostic significance in esophageal cancer.

TI Prevalence of TMPRSS2-ERG Fusion Prostate Cancer among Men Undergoing
Prostate Biopsy in the United States
SO CLINICAL CANCER RESEARCH
LA English
DT Article
ID GENE FUSION; HETEROGENEITY; TRANSCRIPTS; EXPRESSION; URINE
AB Purpose: Fusion of the TMPRSS2 prostate-specific gene with the ERG transcription factor is a putatively oncogenic gene rearrangement that is commonly found in prostate cancer tissue from men undergoing prostatectomy. However, the prevalence of the fusion was less common in samples of transurethral resection of the prostate from a Swedish cohort of patients with incidental prostate cancer followed by watchful waiting, raising the question as to whether the high prevalence in prostatectomy specimens reflects selection bias. We sought to determine the prevalence of TMPRSS2-ERG gene fusion among prostate-specific antigen - screened men undergoing prostate biopsy in the United States.
Experimental Design: We studied 140 prostate biopsies from the same number of patients for TMPRSS2-ERG fusion status with a fluorescent in situ hybridization assay. One hundred and thirty-four samples (100 cancer and 34 benign) were assessable.
Results: ERG gene rearrangement was detected in 46% of prostate biopsies that were found to have prostate cancer and in 0% of benign prostate biopsies (P < 0.0001). Evaluation of morphologic features showed that cribriform growth, blue-tinged mucin, macronucleoli, and collagenous micronodules were significantly more frequent in TMPRSS2-ERG fusion - positive prostate cancer biopsies than gene fusion - negative prostate cancer biopsies (P <= 0.04). No significant association with Gleason score was detected. In addition, non-Caucasian patients were less likely to have positive fusion status (P = 0.02).
Conclusions: This is the first prospective North American multicenter study to characterize TMPRSS2-ERG prostate cancer prevalence in a cohort of patients undergoing needle biopsy irrespective of whether or not they subsequently undergo prostatectomy. Our results show that this gene rearrangement is common among North American men who have prostate cancer on biopsy, is absent in benign prostate biopsy, and is associated with specific morphologic features. These findings indicate a need for prospective studies to evaluate the relationship of TMPRSS2-ERG rearrangement with clinical course of screening-detected prostate cancer in North American men, and a need for the development of noninvasive screening tests to detect TMPRSS2-ERG rearrangement.

AB Background. The association between hepatitis C virus (HCV) infection and coronary artery disease (CAD) is controversial. We conducted this study to determine and quantify this association.
Methods. We used an established, national, observational cohort of all HCV-infected veterans receiving care at all Veterans Affairs facilities, the Electronically Retrieved Cohort of HCV Infected Veterans, to identify HCV-infected subjects and HCV-uninfected control subjects. We used the Cox proportional-hazards model to determine the risk of CAD among HCV-infected subjects and control subjects.
Results. We identified 82,083 HCV-infected and 89,582 HCV-uninfected subjects. HCV-infected subjects were less likely to have hypertension, hyperlipidemia, and diabetes but were more likely to abuse alcohol and drugs and to have renal failure and anemia. HCV-infected subjects had lower mean (+/- standard deviation) total plasma cholesterol (175 +/- 40.8 mg/dL vs. 198 +/- 41.0 mg/dL), low-density lipoprotein cholesterol (102 +/- 36.8 mg/dL vs. 119 +/- 38.2 mg/dL), and triglyceride (144 +/- 119 mg/dL vs. 179 +/- 151 mg/dL) levels, compared with HCV-uninfected subjects (P < .001 for all comparisons). In multivariable analysis, HCV infection was associated with a higher risk of CAD (hazard ratio, 1.25; 95% confidence interval, 1.20-1.30). Traditional risk factors (age, hypertension, chronic obstructive pulmonary disease, diabetes, and hyperlipidemia) were associated with a higher risk of CAD in both groups, whereas minority race and female sex were associated with a lower risk of CAD.
Conclusions. HCV-infected persons are younger and have lower lipid levels and a lower prevalence of hypertension. Despite a favorable risk profile, HCV infection is associated with a higher risk of CAD after adjustment for traditional risk factors.

TI BMP type II receptor regulates positioning of outflow tract and

AB Signaling of bone morphogenetic protein (BMP) via type I and type II receptors is involved in multiple processes contributing to cardiogenesis. To investigate the role of the BMP type II receptor (BMPRII) in heart development, the BMPRII gene was deleted throughout the embryo during gastrulation using a Mox2-Cre transgene. BMPR(flox/-);Mox2-Cre mice exhibited cardiac defects including double-outlet right ventricle, ventricular septal defect (VSD), atrioventricular (AV) cushion defects, and thickened valve leaflets. To characterize the tissue-specific functions of BMPRII in cardiogenesis, a series of Cre transgenes (alpha MHC-, Tie2-, Wnt1-, and SM22 alpha-Cre) was employed. Interestingly, myocardial development was normal when the BMPRII gene was deleted in myocardial cells using Mox2-Cre, alpha MHC-Cre, or SM22 alpha-Cre transgenes, suggesting that signaling by other BMP type II receptors may compensate for the absence of BMPRII in the myocardial cells. AV cushion defects including atrial septal defect, membranous VSD, and thickened valve leaflets were found in BMPR(flox/-);Tie2-Cre mice. Abnormal positioning of the aorta was observed in BMPRII(flox/-);Wnt1-Cre and BMPRII(flox/-);SM22 alpha-Cre mice. Taken together, these results demonstrate that endocardial BMPRII expression is required for septal formation and valvulogenesis. Moreover, mesenchymal BMPRII expression in the outflow tract cushion is required for proper positioning of the aorta. (C) 2009 Elsevier Inc. All rights reserved.

AB The common gastrointestinal pathogens enteropathogenic Escherichia coli (EPEC) and Salmonella typhimurium both reorganize the gut epithelial cell actin cytoskeleton to mediate pathogenesis, utilizing mimicry of the host signaling apparatus. The PDZ domain-containing protein Shank3, is a large cytoskeletal scaffold protein with known functions in neuronal morphology and synaptic signaling, and is also capable of acting as a scaffolding adaptor during Ret tyrosine kinase signaling in epithelial cells. Using immunofluorescent and functional RNA-interference approaches we show that Shank3 is present in both EPEC- and S. typhimurium-induced actin rearrangements and is required for optimal EPEC pedestal formation. We propose that Shank3 is one of a number of host synaptic proteins likely to play key roles in bacteria-host interactions. (C) 2009 Elsevier Inc. All rights reserved.

AB Variation in serum bilirubin is associated with altered cardiovascular disease risk and drug metabolism. We aimed to identify genetic contributors to variability in serum bilirubin levels by combining results from three genome-wide association studies (Framingham heart study, n = 3424; Rotterdam study, n = 3847; Age, Gene, Environment and Susceptibility-Reykjavik, n = 2193). Meta-analysis showed strong replication for a genetic influence on serum bilirubin levels of the UGT1A1 locus (P < 5 x 10(-324)) and a 12p12.2 locus. The peak signal in the 12p12.2 region was a non-synonymous SNP in SLCO1B1 (rs4149056, P = 6.7 x 10(-13)), which gives rise to a valine to alanine amino acid change leading to reduced activity for a hepatic transporter with known affinity for bilirubin. There were also suggestive associations with several other loci. The top variants in UGT1A1 and SLCO1B1 explain similar to 18.0 and similar to 1.0% of the variation in total serum bilirubin levels, respectively. In a conditional analysis adjusted for individual genotypes for the top UGT1A1 variant, the top SLCO1B1 variant remained highly significant (P = 7.3 x 10(-13)), but no other variants achieved genome-wide significance. In one of the largest genetic studies of bilirubin to date (n = 9464), we confirm the substantial genetic influence of UGT1A1 variants, consistent with past linkage and association studies, and additionally provide strong evidence of a role for allelic variation in SLCO1B1. Given the involvement of bilirubin in a number of physiological and disease processes, and the roles for UGT1A1 and SLCO1B1 in drug metabolism, these genetic findings have potential clinical importance. In analyses for association with gallbladder disease or gallstones, top bilirubin SNPs in UGT1A1 and SLCO1B1 were not associated.

AB A family history of colorectal cancer may increase colorectal cancer risk by influencing adenoma growth or enhancing the formation of new lesions. Data of men from the prospective Health Professionals Follow-Up Study who underwent an endoscopy between 1986 and 2004 were used to evaluate whether a family history of colorectal cancer is associated with adenoma multiplicity or advanced adenoma stage (>= 1 cm, histology with villous component or carcinoma in situ). 21.4% of the 3,881 adenoma patients and 13.9% of the 24,959 adenoma-free men had a first-degree relative with colorectal cancer. Thousand four hundred and ninety-six men were classified as having advanced and 1,507 as having nonadvanced adenomas. Six hundred and twenty-two men had multiple and 1,985 had single adenomas in the distal colon and rectum. A family history of colorectal cancer was similarly associated with advanced and nonadvanced adenomas [multivariable odds ratio (OR) (95% confidence interval): advanced vs. nonadvanced, 0.98 (0.82-1.17), advanced vs. adenoma-free: 1.67 (1.47-1.91), nonadvanced vs. adenoma-free: 1.70 (1.49-1.94)], although potential differences according to adenoma location were seen. A family history of colorectal cancer was more strongly associated with multiple distally located adenomas [odds ratio (95% confidence interval): multiple vs. single, 1.35 (1.09-1.68), multiple vs. no distally located adenomas: 2.02 (1.67-2.44), single vs. no distally located adenomas: 1.49 (1.32-1.68)]. The number of adenomas was also positively associated with a family history of colorectal cancer. Our findings suggest that at the population level, heritable factors may be more important in earlier stages of adenoma formation than at stages of adenoma advancement for at least distally located adenomas.

AB Small double stranded RNAs (dsRNA) are a new class of molecules which regulate gene expression. Accumulating data suggest that some dsRNA can function as tumor suppressors. Here, we report further evidence on the potential of dsRNA mediated p21 induction. Using the human renal cell carcinoma cell line A498, we found that dsRNA targeting the p21 promoter significantly induced the expression of p21 mRNA and protein levels. As a result, dsP21 transfected cells had a significant decrease in cell viability with a concomitant G1 arrest. We also observed a significant increase in apoptosis. These findings were associated with a significant decrease in survivin mRNA and protein levels. This is the first report that demonstrates dsRNA mediated gene activation in renal cell carcinoma and suggests that forced over-expression of p21 may lead to an increase in apoptosis through a survivin dependent mechanism.

AB Purpose: To present guidance for patients and physicians regarding the use of accelerated partial-breast irradiation (APBI), based on current published evidence complemented by expert opinion.
Methods and Materials: A systematic search of the National Library of Medicine's PubMed database yielded 645 candidate original research articles potentially applicable to APBI. Of these, 4 randomized trials and 38 prospective single-arm studies were identified. A Task Force composed of all authors synthesized the published evidence and, through a series of meetings, reached consensus regarding the recommendations contained herein.
Results: The Task Force proposed three patient groups: (1) a "suitable: group, for whom APBI outside of a clinical trial is not generally considered warranted. Patients who choose treatment with APBI should be informed that whole-breast irradiation (WBI) is an established treatment with a much longer track record that has documented long-term effectiveness and safety.
Conclusion: Accelerated partial-breast irradiation is a new technology that may ultimately demonstrate long-term effectiveness and safety comparable to that of WBI for selected patients with early breast cancer. This consensus statement is intended to provide guidance regarding the use of APBI outside of a clinical trial and to serve as a framework to promote additional clinical investigations into the optimal role of APBI in the treatment of breast cancer.

AB Purpose: Sunitinib (SU) is a multitargeted receptor tyrosine kinase inhibitor of the vascular endothelial growth factor and platelet-derived growth factor receptors. The present study examined SU and radiotherapy (RT) in a genetically engineered mouse model of soft tissue sarcoma (STS).
Methods and Materials: Primary extremity STSs were generated in genetically engineered mice. The mice were randomized to treatment with SU, RT (10 Gy x 2), or both (SU+RT). Changes in the tumor vasculature before and after treatment were assessed in vivo using fluorescence-mediated tomography. The control and treated tumors were harvested and extensively analyzed.
Results: The mean fluorescence in the tumors was not decreased by RT but decreased 38-44% in tumors treated with SU or SU+RT. The control tumors grew to a mean of 1378 mm(3) after 12 days. SU alone or RT alone delayed tumor growth by 56% and 41%, respectively, but maximal growth inhibition (71%) was observed with the combination therapy. SU target effects were confirmed by loss of target receptor phosphorylation and alterations in SU-related gene expression. Cancer cell proliferation was decreased and apoptosis increased in the SU and RT groups, with a synergistic effect on apoptosis observed in the SU+RT group. RT had a minimal effect on the tumor microvessel density and endothelial cell-specific apoptosis, but SU alone or SU+RT decreased the microvessel density by >66% and induced significant endothelial cell apoptosis.
Conclusion: SU inhibited STS growth by effects on both cancer cells and tumor vasculature. SU also augmented the efficacy of RT, suggesting that this combination strategy could improve local control of STS. (C) 2009 Elsevier Inc.

AB Late tooth morphogenesis is characterized by a series of events that determine crown morphogenesis and the histodifferentiation of epithelial cells into enamel-secreting ameloblasts and of mesenchymal cells into dentin-secreting odontoblasts. Functional ameloblasts are tall, columnar, polarized cells that synthesize and secrete a number of enamel-specific proteins. After depositing the full thickness of enamel matrix, ameloblasts shrink in size and regulate enamel maturation. Amelogenesis imperfecta (AI) is a heterogeneous group of inherited defects in enamel formation. Clinically, AI presents as a spectrum of enamel malformations that are categorized as hypoplastic, hypocalcified, or hypomaturation types, based upon the thickness and hardness of the enamel. The different types of AI are inherited, either as X-linked, autosomal-dominant, or autosomal-recessive traits. Recently, several gene mutations have been identified to cause the subtypes of AI. How these genes, however, coordinate their function to control amelogenesis is not understood. In this review, we discuss the role of genes that play definitive role on the determination of ameloblast cell fate and life cycle based on studies in transgenic animals. J. Exp. Zool. (Mol. Dev.

AB Human clinical trials in type 1 diabetes (T1D) patients using mesenchymal stem cells (MSC) are presently underway without prior validation in a mouse model for the disease. In response to this void, we characterized bone marrow-derived murine MSC for their ability to modulate immune responses in the context of T1D, as represented in NOD mice. In comparison to NOD mice, BALB/c-MSC mice were found to express higher levels of the negative costimulatory molecule PD-L1 and to promote a shift toward Th2-like responses in treated NOD mice. In addition, transfer of MSC from resistant strains (i.e., nonobese resistant mice or BALB/c), but not from NOD mice, delayed the onset of diabetes when administered to prediabetic NOD mice. The number of BALB/c-MSC trafficking to the pancreatic lymph nodes of NOD mice was higher than in NOD mice provided autologous NOD-MSC. Administration of BALB/c-MSC temporarily resulted in reversal of hyperglycemia in 90% of NOD mice (p = 0.002). Transfer of autologous NOD-MSC imparted no such therapeutic benefit. We also noted soft tissue and visceral tumors in NOD-MSC-treated mice, which were uniquely observed in this setting (i.e., no tumors were present with BALB/c- or nonobese resistant mice-MSC transfer). The importance of this observation remains to be explored in humans, as inbred mice such as NOD may be more susceptible to tumor formation. These data provide important preclinical data supporting the basis for further development of allogeneic MSC-based therapies for T1D and, potentially, for other autoimmune disorders.

AB Various neutrophil functions such as phagocytosis, superoxide production, and survival are regulated by integrin signaling. Despite the essential role of focal adhesion kinase (FAK) in mediating this signaling pathway, its exact function in neutrophils is ill defined. In this study, we investigated the role of FAK in neutrophils using a myeloid-specific conditional FAK knockout mouse. As reported in many other cell types, FAK is required for regulation of focal adhesion dynamics when neutrophils adhere to fibronectin or ICAM-1. Adhesion on VCAM-1-coated surfaces and chemotaxis after adhesion were not altered in FAK null neutrophils. In addition, we observed significant reduction in NADPH oxidase-mediated superoxide production and complement-mediated phagocytosis in FAK null neutrophils. As a result, these neutrophils displayed decreased pathogen killing capability both in vitro and in vivo in a mouse peritonitis model. In adherent cells, the defects associated with FAK deficiency are likely due to suppression of phosphatidylinositol (3,4,5)-trisphosphate (PtdIns(3,4,5)P3) signaling and chemoattractant-elicited calcium signaling. Disruption of FAK also reduced chemoattractant-elicited superoxide production in suspended neutrophils in the absence of cell adhesion. This may be solely caused by suppression of PtdIns(3,4,5)P3 signaling in these cells, because the fMLP-elicited calcium signal was not altered. Consistent with decreased PtdIns(3,4,5)P3/Akt signaling in FAK null neutrophils, we also observed accelerated spontaneous death in these cells. Taken together, our results revealed previously unrecognized roles of FAK in neutrophil function and provided a potential therapeutic target for treatment of a variety of infectious and inflammatory diseases.

AB The ability of cytotoxic T lymphocytes (CTLs) to clear virus-infected cells is dependent on the presentation of viral peptides processed intracellularly and displayed by major histocompatibility complex class I. Most CTL functional assays use exogenously added peptides, a practice that does not account for the kinetics and quantity of antigenic peptides produced by infectable cells. Here, we examined the relative ability of 2 major human immunodeficiency virus-infectable cell subsets-CD4 T lymphocytes and monocytes-to produce antigenic peptides, using cytosol as a source of peptidases and mass spectrometry to define the degradation products. We show clear subset-specific differences in the kinetics of peptide production and the ability of the peptides produced to sensitize cells for lysis by CTLs, with primary CD4 T lymphocytes having significantly lower proteolytic activity than monocytes. These differences in epitope processing by cell subsets may affect the efficiency of CTL-mediated clearance of infected subsets and contribute to the establishment of chronic infection.

TI beta-Amyloid Oligomers Induce Phosphorylation of Tau and Inactivation of

AB Both insulin resistance (type II diabetes) and beta-amyloid (A beta) oligomers are implicated in Alzheimer's disease (AD). Here, we investigate the role of A beta oligomer-induced c-Jun N-terminal kinase (JNK) activation leading to phosphorylation and degradation of the adaptor protein insulin receptor substrate-1 (IRS-1). IRS-1 couples insulin and other trophic factor receptors to downstream kinases and neuroprotective signaling. Increased phospho-IRS-1 is found in AD brain and insulin-resistant tissues from diabetics. Here, we report A beta oligomers significantly increased active JNK and phosphorylation of IRS-1 (Ser616) and tau (Ser422) in cultured hippocampal neurons, whereas JNK inhibition blocked these responses. The omega-3 fatty acid docosahexaenoic acid (DHA) similarly inhibited JNK and the phosphorylation of IRS-1 and tau in cultured hippocampal neurons. Feeding 3xTg-AD transgenic mice a diet high in saturated and omega-6 fat increased active JNK and phosphorylated IRS-1 and tau. Treatment of the 3xTg-AD mice on high-fat diet with fish oil or curcumin or a combination of both for 4 months reduced phosphorylated JNK, IRS-1, and tau and prevented the degradation of total IRS-1. This was accompanied by improvement in Y-maze performance. Mice fed with fish oil and curcumin for 1 month had more significant effects on Y-maze, and the combination showed more significant inhibition of JNK, IRS-1, and tau phosphorylation. These data indicate JNK mediates A beta oligomer inactivation of IRS-1 and phospho-tau pathology and that dietary treatment with fish oil/DHA, curcumin, or a combination of both has the potential to improve insulin/trophic signaling and cognitive deficits in AD.

AB Regulation of localized extracellular pH (pH(o)) maintains normal organ function. An alkaline microclimate overlying the duodenal enterocyte brush border protects the mucosa from luminal acid. We hypothesized that intestinal alkaline phosphatase (IAP) regulates pH(o) due to pH-sensitive ATP hydrolysis as part of an ecto-purinergic pH regulatory system, comprised of cell-surface P2Y receptors and ATP-stimulated duodenal bicarbonate secretion (DBS). To test this hypothesis, we measured DBS in a perfused rat duodenal loop, examining the effect of the competitive alkaline phosphatase inhibitor glycerol phosphate (GP), the ecto-nucleoside triphosphate diphosphohydrolase inhibitor ARL67156, and exogenous nucleotides or P2 receptor agonists on DBS. Furthermore, we measured perfusate ATP concentration with a luciferin-luciferase bioassay. IAP inhibition increased DBS and luminal ATP output. Increased luminal ATP output was partially CFTR dependent, but was not due to cellular injury. Immunofluorescence localized the P2Y(1) receptor to the brush border membrane of duodenal villi. The P2Y(1) agonist 2-methylthio-ADP increased DBS, whereas the P2Y(1) antagonist MRS2179 reduced ATP- or GP-induced DBS. Acid perfusion augmented DBS and ATP release, further enhanced by the IAP inhibitor l-cysteine, and reduced by the exogenous ATPase apyrase. Furthermore, MRS2179 or the highly selective P2Y(1) antagonist MRS2500 co-perfused with acid induced epithelial injury, suggesting that IAP/ATP/P2Y signalling protects the mucosa from acid injury. Increased DBS augments IAP activity presumably by raising pH(o), increasing the rate of ATP degradation, decreasing ATP-mediated DBS, forming a negative feedback loop. The duodenal epithelial brush border IAP-P2Y-HCO3- surface microclimate pH regulatory system effectively protects the mucosa from acid injury.

AB The generation of humanized BLT mice by the cotransplantation of human fetal thymus and liver tissues and CD34(+) fetal liver cells into nonobese diabetic/severe combined immunodeficiency mice allows for the long-term reconstitution of a functional human immune system, with human T cells, B cells, dendritic cells, and monocytes/macrophages repopulating mouse tissues. Here, we show that humanized BLT mice sustained high-level disseminated human immunodeficiency virus (HIV) infection, resulting in CD4(+) T-cell depletion and generalized immune activation. Following infection, HIV-specific humoral responses were present in all mice by 3 months, and HIV-specific CD4(+) and CD8(+) T-cell responses were detected in the majority of mice tested after 9 weeks of infection. Despite robust HIV-specific responses, however, viral loads remained elevated in infected BLT mice, raising the possibility that these responses are dysfunctional. The increased T-cell expression of the negative costimulator PD-1 recently has been postulated to contribute to T-cell dysfunction in chronic HIV infection. As seen in human infection, both CD4(+) and CD8(+) T cells demonstrated increased PD-1 expression in HIV-infected BLT mice, and PD-1 levels in these cells correlated positively with viral load and inversely with CD4(+) cell levels. The ability of humanized BLT mice to generate both cellular and humoral immune responses to HIV will allow the further investigation of human HIV-specific immune responses in vivo and suggests that these mice are able to provide a platform to assess candidate HIV vaccines and other immunotherapeutic strategies.

AB Pax7 is a key regulator of skeletal muscle stem cells and is required along with Pax3 to generate skeletal muscle precursors. We have identified a collection of genes induced by either Pax3 or Pax7 in C2C12 muscle cells. Two notable Pax3/7 targets are the inhibitory helix-loop-helix (HLH) proteins inhibitor of DNA binding (Id) 2 and Id3, both of which are coordinately expressed with Pax7 in quiescent satellite cells and are induced in quiescent C2C12 myogenic cells after ectopic expression of either Pax3 or Pax7. Ectopic Pax7 activates expression of a luciferase reporter driven by the Id3 promoter, and maximal induction of this reporter requires a conserved Pax7 binding site located upstream of the Id3 gene. Chromatin immunoprecipitation indicated that Pax7 is bound upstream of the Id3 promoter in quiescent satellite cells. In addition, short hairpin RNA-mediated knockdown of Pax7 expression in cultured satellite cells coordinately decreased both Id2 and Id3 expression. Together, these findings indicate that Id3 is a direct transcriptional target for Pax7 in quiescent satellite cells, and they suggest that Pax7 acts to block premature differentiation of quiescent satellite cells by inducing the expression of Id2 and Id3, which in turn may act to block either the precocious induction of myogenic basic (b) HLH proteins, the activity of myogenic bHLH proteins, or both.

TI SWI/SNF Deficiency Results in Aberrant Chromatin Organization, Mitotic

AB Switch (SWI)/sucrose nonfermentable (SNF) is an evolutionarily conserved complex with ATPase function, capable of regulating nucleosome position to alter transcriptional programs within the cell. It is known that the SWI/SNF complex is responsible for regulation of many genes involved in cell cycle control and proliferation, and it has recently been implicated in cancer development. The ATPase action of SWI/SNF is conferred through either the brahma-related gene 1 (Brg1) or brahma (Brm) subunit of the complex, and it is of central importance to the modification of nucleosome position. In this study, the role of the Brg1 and Brm subunits were examined as they relate to chromatin structure and organization. Deletion of the Brg1 ATPase results in dissolution of pericentromeric heterochromatin domains and a redistribution of histone modifications associated with these structures. This effect was highly specific to Brg1 and is not reproduced by the loss of Brm or SNF5/BAF47/INI1. Brg1 deficiency is associated with the appearance of micronuclei and aberrant mitoses that are a by-product of dissociated chromatin structure. Thus, Brg1 plays a critical role in maintaining chromatin structural integrity.

TI Cdh1 Regulates Cell Cycle through Modulating the Claspin/Chk1 and the

AB APC/Cdh1 is a major cell cycle regulator and its function has been implicated in DNA damage repair; however, its exact role remains unclear. Using affinity purification coupled with mass spectrometry, we identified Claspin as a novel Cdh1-interacting protein and further demonstrated that Claspin is a novel Cdh1 ubiquitin substrate. As a result, inactivation of Cdh1 leads to activation of the Claspin/Chk1 pathway. Previously, we demonstrated that Rb interacts with Cdh1 to influence its ability to degrade Skp2. Here, we report that Cdh1 reciprocally regulates the Rb pathway through competing with E2F1 to bind the hypophosphorylated form of Rb. Although inactivation of Cdh1 in HeLa cells, with defective p53/Rb pathways, led to premature S phase entry, acute depletion of Cdh1 in primary human fibroblasts resulted in premature senescence. Acute loss of many other major tumor suppressors, including PTEN and VHL, also induces premature senescence in a p53- or Rb-dependent manner. Similarly, we showed that inactivation of the p53/Rb pathways by overexpression of SV40 LT-antigen partially reversed Cdh1 depletion-induced growth arrest. Therefore, loss of Cdh1 is only beneficial to cells with abnormal p53 and Rb pathways, which helps explain why Cdh1 loss is not frequently found in many tumors.

AB To determine if reproductive factors or exogenous estrogen are associated with risk of Parkinson's disease (PD), we conducted a prospective study with 22 years of follow-up among postmenopausal participants in the Nurses' Health Study. Relative risks (RRs) and 95% confidence intervals (CIs) of PD were estimated from a Cox proportional hazards model adjusting for potential confounders. Risk of PD was not significantly associated with any of the reproductive factors measured or exogenous estrogen use. Use of postmenopausal hormones, however, may modify the associations of smoking and caffeine intake with PD risk. The inverse relation between smoking and PD risk was attenuated among ever users of post-menopausal hormones (P for interaction = 0.05). Similar results were obtained for caffeine (P for interaction = 0.09). In exploratory analyses, women using progestin-only hormones were found to have an increased PD risk, but this result was based on a very small number of cases (n = 4). In this large longitudinal study, we found no evidence of a beneficial effect of exogenous or endogenous estrogens on risk of PD. The use of postmenopausal hormone use may interact with other risk factors, but findings are preliminary and need confirmation in other populations. (C) 2009 Movement Disorder Society

AB Multiple studies indicate that adenosine released in the basal forebrain during prolonged wakefulness could affect recovery sleep. It is still unclear which of adenosine receptors provide its sleep-modulating effects in the basal forebrain. We infused adenosine A(1) and A(2A) receptors antagonists into the rat basal forebrain during sleep deprivation and compared characteristics of recovery non-rapid eye movement (non-REM) sleep (its amount and non-REM sleep delta power) after sleep deprivation, and after sleep deprivation combined with perfusion of antagonists. A(1) receptor antagonist significantly reduced recovery sleep amount and delta power, whereas A(2A) receptor antagonist had no effect on recovery sleep. We conclude that adenosine can promote recovery non-REM sleep when acting through A(1) receptors in the basal forebrain.

AB Previous diffusion tensor imaging (DTI) studies indicated microstructural disruption of white matter in alcohol dependence. To investigate the microstructure of primary neurocircuitry involved in alcohol use disorders, the present study used Tract-Based Spatial Statistics (TBSS) of DTI measures as well as probabilistic tractography. Eleven recovering alcoholics in their first week of abstinence from alcohol were compared with 10 light-drinking controls; diffusion measures were correlated with measures of neurocognition and drinking severity. Regions characterized by low fractional anisotropy and high mean diffusivity included cortico-striatal fibers and those in frontal white matter and limbic pathways. Greater diffusion abnormalities in sections of commissural fibers (inter-hemispheric connections) were associated with greater drinking severity, and lower fractional anisotropy measures in frontal and limbic fiber tracts correlated with lower visuospatial memory performance. These study findings provide direct evidence of compromised integrity of the motivational brain circuitry in alcohol use disorders. These abnormalities in fiber connections could be partially responsible for deficiencies in executive functions, behavioral regulation, and impulse control commonly described in alcohol dependence.

GUIDELINES; CRITERIA LIST; METAANALYSES
AB Study Design. We conducted a methodologic study. Objective. The objective of this study was to assess the validity of the criteria list recommended by the Cochrane Back Review Group Editorial Board by evaluating whether individual items and a total score are associated with effect sizes in randomized controlled trials of back-pain interventions.
Summary of Background Data. There is concern that studies of low methodologic quality may exaggerate the effectiveness of treatments for low back pain. We performed this study to examine the association between a common measure of internal validity and the reported magnitude of treatment effects.
Methods. We assessed the relationship between the 11 items contained in the Cochrane Back Review Group Internal Validity checklist and effect size in randomized trials of interventions for back pain. Of 267 trials in 15 Cochrane reviews that were eligible for inclusion, 51 were excluded, leaving 216 trials included in the analysis. The scores on the 11 items for each trial were taken from the original review. We extracted effect sizes from each low back pain trial.
Results. We found that trials that fulfilled a specific item had smaller effect sizes compared with trials that did not fulfill that item for 10 of the 11 items, and for 6 of the criteria, the absolute difference in effect sizes was 0.10 or greater. The 95% confidence interval of the difference in effect sizes crossed the null value in each case. The number of items fulfilled showed that trials with higher scores consistently reported smaller effect sizes than trials with lower scores. At the thresholds of 5 or 6 items fulfilled, the difference in effect sizes was 0.20 in each case (95% confidence intervals 0.05-0.35 and 0.06-0.34, respectively). Stratified analyses did not support confounding by intervention.
Conclusion. We conclude that the 11-item Internal Validity Checklist is associated with effect size in randomized trials of interventions for back pain, and that our data support the use of a sum score of the number of fulfilled items in this list.

AB Background. Nuclear transfer has been used as a means of selectively modifying the mammalian genome. One possible consequence of this technology is that the oocytes used in nuclear transfer may provide additional antigens by cytoplasmic inheritance of maternally derived, mitochondrial DNA (mtDNA). These studies examine the potential consequences of such inheritance in a large animal transplantation model.
Methods. Renal transplants were performed between major histocompatibility complex (MHC)-identical animals differing only in the source of their maternally derived cytoplasmic DNA, using a protocol, which uniformly leads to tolerance within standard MFIC-inbred lines. In an attempt to correlate transplant results with a putative marker for disparities in cytoplasmically inherited minor histocompatibility antigens, we examined one hypervariable region of mtDNA, designated hypervariable region 1 (HV1).
Results. The mtDNA sequence of the HV1 region was found to be invariant among MGH miniature swine of different haplotypes, despite 25 years of selective breeding of the sublines of this colony. In contrast, swine derived by nuclear transfer into outbred oocytes differed in the HV1 region sequence from each other and from MGH swine. Renal transplants from standard, inbred. MGH swine to their MHC-identical knockout counterparts derived from outbred oocytes were rejected within 2 weeks, whereas transplants in the reverse direction were accepted for over 30 days.
Conclusions. The HV1 sequence of mtDNA may serve as a marker for the level of diversity of mtDNA. These transplant data are consistent with the existence of mtDNA-encoded mitochondrial minor antigens with a level of diversity that can influence the outcome of renal transplantation.

ID ACCELERATED NODULOSIS; ARTHRITIS; THERAPY
AB Background: Rheumatoid nodules are the most common extra-articular findings in patients with rheumatoid arthritis. They occur most commonly at pressure points such as the extensor surfaces of the forearms, fingers, and occiput, but have also been reported to occur in unusual locations including the central nervous system, pericardium, pleura, and sclera. We present the unusual case of rheumatoid nodules in the small bowel mesentery masquerading as an intra-abdominal malignancy.
Case presentation: A 65-year-old-male with a known history of longstanding erosive, nodular, seropositive rheumatoid arthritis was incidentally found to have a mesenteric mass on computed tomography (CT) exam of the abdomen. This mass had not been present on prior imaging studies and was worrisome for a malignancy. Attempts at noninvasive biopsy were nondiagnostic but consistent with a "spindle" cell neoplasm. Laparotomy revealed extensive thickening and fibrosis of the small bowel mesentery along with large, firm nodules throughout the mesentery. A limited bowel resection including a large, partially obstructing, nodule was performed. Pathology was consistent with an unusual presentation of rheumatoid nodules in the mesentery of the small bowel.
Conclusion: Rheumatoid nodules should be considered in the differential diagnosis of a patient who presents with an intra-abdominal mass and a history of rheumatoid arthritis. Currently, no tests or imaging modality can discriminate with sufficient accuracy to rule out a malignancy in this difficult diagnostic delimma. Hopefully, this case will serve as impetus for further study and biomarker discovery to allow for improved diagnostic power.

TI Serum and follicular fluid organochlorine concentrations among women
undergoing assisted reproduction technologies

UNITED-STATES; EXPOSURE; PREGNANCY; BLOOD; PLASMA; DDT; PCB
AB Background: Exposure to persistent organic pollutants, including polychlorinated biphenyls (PCBs) and organochlorine pesticides, is widespread among the general population. There is evidence of adverse effects on reproduction and early pregnancy in relation to organochlorine exposure but human studies remain limited. The increased use of assisted reproductive technologies (ART) presents unique opportunities for the assessment of environmental influences on early pregnancy outcomes not otherwise observable in humans, but studies need to be designed to maximize the efficiency of the exposure data collected while minimizing exposure measurement error.
Methods: The present study was conducted to assess the correlation between concentrations of organochlorines in serum and follicular fluid samples collected from a subset of women undergoing ART in a large study that took place between 1994 and 2003, as well as the temporal reliability of serum organochlorine concentrations among women undergoing multiple ART cycles in the study. PCB congeners (118, 138, 153, and 180), 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (p, p'-DDT), the DDT metabolite p, p'-DDE, hexachlorobenzene (HCB), oxychlordane, trans-nonachlor and mirex were measured in 72 follicular fluid samples and 265 serum samples collected from 110 women.
Results: Organochlorine concentrations in paired serum and follicular fluid samples were correlated, with Pearson and Spearman coefficients ranging from 0.60 to 0.92. Serum organochlorine concentrations were two- to three-fold greater than in follicular fluid, and a significant inverse trend was observed in the distribution of follicular fluid: serum ratios with increasing molecular weight of the compound (p-value for trend < 0.0001). Serum organochlorine concentrations were highly reliable over the course of several months, with intraclass correlation coefficients ranging from 0.86 to 0.98. Finally, there was evidence for a declining trend in organochlorine concentrations between samples collected between years 1994-1998 and those collected in 1999-2003.
Conclusion: Our results support the use of a single serum sample to adequately represent a more biologically relevant dose (concentrations in follicular fluid), as well as exposure levels over time, in epidemiological studies of ART outcomes in relation to organochlorine exposure.

AB Background: The Promoting Action on Research Implementation in Health Services, or PARIHS, framework is a theoretical framework widely promoted as a guide to implement evidence-based clinical practices. However, it has as yet no pool of validated measurement instruments that operationalize the constructs defined in the framework. The present article introduces an Organizational Readiness to Change Assessment instrument (ORCA), organized according to the core elements and sub-elements of the PARIHS framework, and reports on initial validation.
Methods: We conducted scale reliability and factor analyses on cross-sectional, secondary data from three quality improvement projects (n = 80) conducted in the Veterans Health Administration. In each project, identical 77-item ORCA instruments were administered to one or more staff from each facility involved in quality improvement projects. Items were organized into 19 subscales and three primary scales corresponding to the core elements of the PARIHS framework: (1) Strength and extent of evidence for the clinical practice changes represented by the QI program, assessed with four subscales, (2) Quality of the organizational context for the QI program, assessed with six subscales, and (3) Capacity for internal facilitation of the QI program, assessed with nine subscales.
Results: Cronbach's alpha for scale reliability were 0.74, 0.85 and 0.95 for the evidence, context and facilitation scales, respectively. The evidence scale and its three constituent subscales failed to meet the conventional threshold of 0.80 for reliability, and three individual items were eliminated from evidence subscales following reliability testing. In exploratory factor analysis, three factors were retained. Seven of the nine facilitation subscales loaded onto the first factor; five of the six context subscales loaded onto the second factor; and the three evidence subscales loaded on the third factor. Two subscales failed to load significantly on any factor. One measured resources in general (from the context scale), and one clinical champion role (from the facilitation scale).
Conclusion: We find general support for the reliability and factor structure of the ORCA. However, there was poor reliability among measures of evidence, and factor analysis results for measures of general resources and clinical champion role did not conform to the PARIHS framework. Additional validation is needed, including criterion validation.

AB Dynamic obstruction to left ventricular (LV) outflow was recognized from the earliest (50 years ago) clinical descriptions of hypertrophic cardiomyopathy (HCM) and has proved to be a complex phenomenon unique in many respects, as well as arguably the most visible and well-known pathophysiologic component of this heterogeneous disease. Over the past 5 decades, the clinical significance attributable to dynamic LV outflow tract gradients in HCM has triggered a periodic and instructive debate. Nevertheless, only recently has evidence emerged from observational analyses in large patient cohorts that unequivocally supports subaortic pressure gradients (and obstruction) both as true impedance to LV outflow and independent determinants of disabling exertional symptoms and cardiovascular mortality. Furthermore, abolition of subaortic gradients by surgical myectomy (or percutaneous alcohol septal ablation) results in profound and consistent symptomatic benefit and restoration of quality of life, with myectomy providing a long-term survival similar to that observed in the general population. These findings resolve the long-festering controversy over the existence of obstruction in HCM and whether outflow gradients are clinically important elements of this complex disease. These data also underscore the important principle, particularly relevant to clinical practice, that heart failure due to LV outflow obstruction in HCM is mechanically reversible and amenable to invasive septal reduction therapy. Finally, the recent observation that the vast majority of patients with HCM have the propensity to develop outflow obstruction (either at rest or with exercise) underscores a return to the characterization of HCM in 1960 as a predominantly obstructive disease.

AB We recently showed that the mammalian genome encodes >1,000 large intergenic noncoding (linc) RNAs that are clearly conserved across mammals and, thus, functional. Gene expression patterns have implicated these lincRNAs in diverse biological processes, including cell-cycle regulation, immune surveillance, and embryonic stem cell pluripotency. However, the mechanism by which these lincRNAs function is unknown. Here, weexpand the catalog of human lincRNAs to approximate to 3,300 by analyzing chromatin-state maps of various human cell types. Inspired by the observation that the well-characterized lincRNA HOTAIR binds the polycomb repressive complex (PRC) 2, we tested whether many lincRNAs are physically associated with PRC2. Remarkably, we observe that approximate to 20% of lincRNAs expressed in various cell types are bound by PRC2, and that additional lincRNAs are bound by other chromatin-modifying complexes. Also, we show that siRNA-mediated depletion of certain lincRNAs associated with PRC2 leads to changes in gene expression, and that the up-regulated genes are enriched for those normally silenced by PRC2. We propose a model in which some lincRNAs guide chromatin-modifying complexes to specific genomic loci to regulate gene expression.

AB Idiopathic hypogonadotropic hypogonadism (IHH) is a condition characterized by failure to undergo puberty in the setting of low sex steroids and low gonadotropins. IHH is due to abnormal secretion or action of the master reproductive hormone gonadotropin-releasing hormone (GnRH). Several genes have been found to be mutated in patients with IHH, yet to date no mutations have been identified in the most obvious candidate gene, GNRH1 itself, which encodes the preprohormone that is ultimately processed to produce GnRH. We screened DNA from 310 patients with normosmic IHH (nIHH) and 192 healthy control subjects for sequence changes in GNRH1. In 1 patient with severe congenital nIHH (with micropenis, bilateral cryptorchidism, and absent puberty), a homozygous frameshift mutation that is predicted to disrupt the 3 C-terminal amino acids of the GnRH decapeptide and to produce a premature stop codon was identified. Heterozygous variants not seen in controls were identified in 4 patients with nIHH: 1 nonsynonymous missense mutation in the eighth amino acid of the GnRH decapeptide, 1 nonsense mutation that causes premature termination within the GnRH-associated peptide (GAP), which lies C-terminal to the GnRH decapeptide within the GnRH precursor, and 2 sequence variants that cause nonsynonymous amino-acid substitutions in the signal peptide and in GnRH-associated peptide. Our results establish mutations in GNRH1 as a genetic cause of nIHH.

TI Pathogenic infection of Macaca nemestrina with a CCR5-tropic subtype-C

AB Background: Although pig-tailed macaques (Macaca nemestrina) have been used in AIDS research for years, less is known about the early immunopathogenic events in this species, as compared to rhesus macaques (Macaca mulatta). Similarly, the events in early infection are well-characterized for simian immunodeficiency viruses (SIV), but less so for chimeric simian-human immunodeficiency viruses (SHIV), although the latter have been widely used in HIV vaccine studies. Here, we report the consequences of intrarectal infection with a CCR5-tropic clade C SHIV-1157ipd3N4 in pig-tailed macaques.
Results: Plasma and cell-associated virus was detectable in peripheral blood and intestinal tissues of all four pig-tailed macaques following intrarectal inoculation with SHIV-1157ipd3N4. We also observed a rapid and irreversible loss of CD4(+) T cells at multiple mucosal sites, resulting in a marked decrease of CD4:CD8 T cell ratios 0.5-4 weeks after inoculation. This depletion targeted subsets of CD4(+) T cells expressing the CCR5 coreceptor and having a CD28-CD95(+) effector memory phenotype, consistent with the R5-tropism of SHIV-1157ipd3N4. All three animals that were studied beyond the acute phase seroconverted as early as week 4, with two developing cross-clade neutralizing antibody responses by week 24. These two animals also demonstrated persistent plasma viremia for > 48 weeks. One of these animals developed AIDS, as shown by peripheral blood CD4(+) T-cell depletion starting at 20 weeks post inoculation.
Conclusion: These findings indicate that SHIV-1157ipd3N4-induced pathogenesis in pig-tailed macaques followed a similar course as SIV-infected rhesus macaques. Thus, R5 SHIV-C-infection of pig-tailed macaques could provide a useful and relevant model for AIDS vaccine and pathogenesis research.

AB Background: Well-documented shortages of health care workers in sub-Saharan Africa are exacerbated by the increased human resource demands of rapidly expanding HIV care and treatment programmes. The successful continuation of existing programmes is threatened by health care worker burnout and HIV-related illness.
Methods: From March to June 2007, we studied occupational burnout and utilization of HIV services among health providers in the Lusaka public health sector. Providers from 13 public clinics were given a 36-item, self-administered questionnaire and invited for focus group discussions and key-informant interviews.
Results: Some 483 active clinical staff completed the questionnaire (84% response rate), 50 staff participated in six focus groups, and four individuals gave interviews. Focus group participants described burnout as feeling overworked, stressed and tired. In the survey, 51% reported occupational burnout. Risk factors were having another job (RR 1.4 95% CI 1.2-1.6) and knowing a co-worker who left in the last year (RR 1.6 95% CI 1.3-2.2). Reasons for co-worker attrition included: better pay (40%), feeling overworked or stressed (21%), moving away (16%), death (8%) and illness (5%). When asked about HIV testing, 370 of 456 (81%) reported having tested; 240 (50%) tested in the last year. In contrast, discussion groups perceived low testing rates. Both discussion groups and survey respondents identified confidentiality as the prime reason for not undergoing HIV testing.
Conclusion: In Lusaka primary care clinics, overwork, illness and death were common reasons for attrition. Programmes to improve access, acceptability and confidentiality of health care services for clinical providers and to reduce workplace stress could substantially affect workforce stability.

AB We present a method for testing overrepresentation of biological pathways, indexed by gene-ontology terms, in lists of significant SNPs from genome-wide association studies. This method corrects for linkage disequilibrium between SNPs, variable gene size, and multiple testing of nonindependent pathways. The method was applied to the Wellcome Trust Case-Control Consortium Crohn disease (CD) data set. At a general level, the biological basis of CD is relatively well known for a complex genetic trait, and it thus acted as a test of the method. The method, known as ALIGATOR (Association LIst Go AnnoTatOR), successfully detected biological pathways implicated in CD. The method was also applied to a meta-analysis of bipolar disorder, and it implicated the modulation of transcription and cellular activity, including that which occurs via hormonal action, as an important player in pathogenesis.

AB Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive paralysis due to motor neuron degeneration. Despite the fact that many different therapeutic strategies have been applied to prevent disease progression, no cure or effective therapy is currently available for ALS. We found that L-arginine protects cultured motor neurons from excitotoxic injury. We also found that L-arginine supplementation both prior to and after the onset of motor neuron degeneration in mtSOD1 (G93A) transgenic ALS mice significantly slowed the progression of neuropathology in lumbar spinal cord, delayed onset of motor dysfunction, and prolonged life span. Moreover, L-arginine treatment was associated with preservation of arginase I activity and neuroprotective polyamines in spinal cord motor neurons. Our findings show that L-arginine has potent in vitro and in vivo neuroprotective properties and may be a candidate for therapeutic trials in ALS. Published by Elsevier Inc

AB Structure-specific endonucleases mediate cleavage of DNA structures formed during repair of collapsed replication forks and double-strand breaks (DSBs). Here, we identify BTBD12 as the human ortholog of the budding yeast DNA repair factor Slx4p and D. melanogaster MUS312. Human SLX4 forms a multiprotein complex with the ERCC4(XPF)-ERCC1, MUS81-EME1, and SLX1 endonucleases and also associates with MSH2/MSH3 mismatch repair complex, telomere binding complex TERF2(TRF2)-TERF2IP(RAP1), the protein kinase PLK1 and the uncharacterized protein C20orf94. Depletion of SLX4 causes sensitivity to mitomycin C and camptothecin and reduces the efficiency of DSB repair in vivo. SLX4 complexes cleave 3' flap, 5' flap, and replication fork structures; yet unlike other endonucleases associated with SLX4, the SLX1-SLX4 module promotes symmetrical cleavage of static and migrating Holliday junctions (HJs), identifying SLX1-SLX4 as a HJ resolvase. Thus, SLX4 assembles a modular toolkit for repair of specific types of DNA lesions and is critical for cellular responses to replication fork failure.

AB The transcriptional control of CNS myelin gene expression is poorly understood. Here we identify gene model 98, which we have named myelin gene regulatory factor (MRF), as a transcriptional regulator required for CNS myelination. Within the CNS, MRF is specifically expressed by postmitotic oligodendrocytes. MRF is a nuclear protein containing an evolutionarily conserved DNA binding domain homologous to a yeast transcription factor. Knockdown of MRF in oligodendrocytes by RNA interference prevents expression of most CNS myelin genes; conversely, overexpression of MRF within cultured oligodendrocyte progenitors or the chick spinal cord promotes expression of myelin genes. In mice lacking MRF within the oligodendrocyte lineage, premyelinating oligodendrocytes are generated but display severe deficits in myelin gene expression and fail to myelinate. These mice display severe neurological abnormalities and die because of seizures during the third postnatal week. These findings establish MRF as a critical transcriptional regulator essential for oligodendrocyte maturation and CNS myelination.

TI PPAR delta Agonism Activates Fatty Acid Oxidation via PGC-1 alpha but
Does Not Increase Mitochondrial Gene Expression and Function

AB PPAR delta (peroxisome proliferator-activated receptor delta) is a regulator of lipid metabolism and has been shown to induce fatty acid oxidation (FAO). PPAR delta transgenic and knock-out mice indicate an involvement of PPAR delta in regulating mitochondrial biogenesis and oxidative capacity; however, the precise mechanisms by which PPAR delta regulates these pathways in skeletal muscle remain unclear. In this study, we determined the effect of selective PPAR delta agonism with the synthetic ligand, GW501516, on FAO and mitochondrial gene expression in vitro and in vivo. Our results show that activation of PPAR delta by GW501516 led to a robust increase in mRNA levels of key lipid metabolism genes. Mitochondrial gene expression and function were not induced under the same conditions. Additionally, the activation of Pdk4 transcription by PPAR delta was coactivated by PGC-1 alpha. PGC-1 alpha, but not PGC-1 beta, was essential for full activation of Cpt-1b and Pdk4 gene expression via PPAR beta agonism. Furthermore, the induction of FAO by PPAR delta agonism was completely abolished in the absence of both PGC-1 alpha and PGC-1 beta Conversely, PGC-1 alpha-driven FAO was independent of PPAR delta. Neither GW501516 treatment nor knockdown of PPAR delta affects PGC-1 alpha-induced mitochondrial gene expression in primary myotubes. These results demonstrate that pharmacological activation of PPAR delta induces FAO via PGC-1 alpha. However, PPAR delta agonism does not induce mitochondrial gene expression and function. PGC-1 alpha-induced FAO and mitochondrial biogenesis appear to be independent of PPAR delta.

AB The potential role of amelogenin phosphorylation in enamel formation is elucidated through in vitro mineralization studies. Studies focused on the native 20-kDa porcine amelogenin proteolytic cleavage product P148 that is prominent in developing enamel. Experimental conditions supported spontaneous calcium phosphate precipitation with the initial formation of amorphous calcium phosphate (ACP). In the absence of protein, ACP was found to undergo relatively rapid transformation to randomly oriented plate-like apatitic crystals. In the presence of non-phosphorylated recombinant full-length amelogenin, rP172, a longer induction period was observed during which relatively small ACP nanoparticles were transiently stabilized. In the presence of rP172, these nanoparticles were found to align to form linear needle-like particles that subsequently transformed and organized into parallel arrays of apatitic needle-like crystals. In sharp contrast to these findings, P148, with a single phosphate group on serine 16, was found to inhibit calcium phosphate precipitation and stabilize ACP formation for more than 1 day. Additional studies using non- phosphorylated recombinant (rP147) and partially dephosphorylated forms of P148 (dephoso-P148) showed that the single phosphate group in P148 was responsible for the profound effect on mineral formation in vitro. The present study has provided, for the first time, evidence suggesting that the native proteolytic cleavage product P148 may have an important functional role in regulating mineralization during enamel formation by preventing unwanted mineral formation within the enamel matrix during the secretory stage of amelogenesis. Results obtained have also provided new insights into the functional role of the highly conserved hydrophilic C terminus found in full-length amelogenin. found in full-length amelogenin.

ID DIETARY RESTRICTION; ADULT MALE; LIFE-SPAN; MACAQUES
AB Caloric restriction (CR), without malnutrition, delays aging and extends life span in diverse species; however, its effect on resistance to illness and mortality in primates has not been clearly established. We report findings of a 20-year longitudinal adult-onset CR study in rhesus monkeys aimed at filling this critical gap in aging research. In a population of rhesus macaques maintained at the Wisconsin National Primate Research Center, moderate CR lowered the incidence of aging-related deaths. At the time point reported, 50% of control fed animals survived as compared with 80% of the CR animals. Furthermore, CR delayed the onset of age-associated pathologies. Specifically, CR reduced the incidence of diabetes, cancer, cardiovascular disease, and brain atrophy. These data demonstrate that CR slows aging in a primate species.

AB Murine models indicate that interleukin-10 (IL-10) can suppress viral clearance, and interventional blockade of IL-10 activity has been proposed to enhance immunity in chronic viral infections. Increased IL-10 levels have been observed during HIV infection and IL-10 blockade has been shown to enhance T-cell function in some HIV-infected subjects. However, the categories of individuals in whom the IL-10 pathway is up-regulated are poorly defined, and the cellular sources of IL-10 in these subjects remain to be determined. Here we report that blockade of the IL-10 pathway augmented in vitro proliferative capacity of HIV-specific CD4 and CD8 T cells in individuals with ongoing viral replication. IL-10 blockade also increased cytokine secretion by HIV-specific CD4 T cells. Spontaneous IL-10 expression, measured as either plasma IL-10 protein or IL-10 mRNA in peripheral blood mononuclear cells (PBMCs), correlated positively with viral load and diminished after successful antiretroviral therapy. IL-10 mRNA levels were up-regulated in multiple PBMC subsets in HIV-infected subjects compared with HIV-negative controls, particularly in T, B, and natural killer (NK) cells, whereas monocytes were a major source of IL-10 mRNA in HIV-infected and -uninfected individuals. These data indicate that multiple cell types contribute to IL-10-mediated immune suppression in the presence of uncontrolled HIV viremia. (Blood. 2009; 114: 346-356)

AB Decreased activity of osteoblasts (OBs) contributes to osteolytic lesions in multiple myeloma (MM). The production of the soluble Wnt inhibitor Dickkopf-1 (DKK1) by MM cells inhibits OB activity, and its serum level correlates with focal bone lesions in MM. Therefore, we have evaluated bone anabolic effects of a DKK1 neutralizing antibody (BHQ880) in MM. In vitro BHQ880 increased OB differentiation, neutralized the negative effect of MM cells on osteoblastogenesis, and reduced IL-6 secretion. In a severe combined immunodeficiency (SCID)-hu murine model of human MM, BHQ880 treatment led to a significant increase in OB number, serum human osteocalcin level, and trabecular bone. Although BHQ880 had no direct effect on MM cell growth, it significantly inhibited growth of MM cells in the presence of bone marrow stromal cells (BMSCs) in vitro. This effect was associated with inhibition of BMSC/MM cell adhesion and production of IL-6. In addition, BHQ880 up-regulated beta-catenin level while down-regulating nuclear factor-kappa B (NF-kappa B) activity in BMSC. Interestingly, we also observed in vivo inhibition of MM cell growth by BHQ880 treatment in the SCID-hu murine model. These results confirm DKK1 as an important therapeutic target in myeloma and provide the rationale for clinical evaluation of BHQ880 to improve bone disease and to inhibit MM growth.

AB Background: Meningiomas may occur either as familial tumors in two distinct disorders, familial multiple meningioma and neurofibromatosis 2 (NF2), or sporadically, as either single or multiple tumors in individuals with no family history. Meningiomas in NF2 and approximately 60% of sporadic meningiomas involve inactivation of the NF2 locus, encoding the tumor suppressor merlin on chromosome 22q. This study was undertaken to establish whether genomic profiling could distinguish familial multiple meningiomas from sporadic solitary and sporadic multiple meningiomas.
Methods: We compared 73 meningiomas presenting as sporadic solitary (64), sporadic multiple (5) and familial multiple (4) tumors using genomic profiling by array comparative genomic hybridization (array CGH).
Results: Sporadic solitary meningiomas revealed genomic rearrangements consistent with at least two mechanisms of tumor initiation, as unsupervised cluster analysis readily distinguished tumors with chromosome 22 deletion (associated with loss of the NF2 tumor suppressor) from those without chromosome 22 deletion. Whereas sporadic meningiomas without chromosome 22 loss exhibited fewer chromosomal imbalance events overall, tumors with chromosome 22 deletion further clustered into two major groups that largely, though not perfectly, matched with their benign (WHO Grade I) or advanced (WHO Grades II and III) histological grade, with the latter exhibiting a significantly greater degree of genomic imbalance (P < 0.001). Sporadic multiple meningiomas showed a frequency of genomic imbalance events comparable to the atypical grade solitary tumors. By contrast, familial multiple meningiomas displayed no imbalances, supporting a distinct mechanism for the origin for these tumors.
Conclusion: Genomic profiling can provide an unbiased adjunct to traditional meningioma classification and provides a basis for exploring the different genetic underpinnings of tumor initiation and progression. Most importantly, the striking difference observed between sporadic and familial multiple meningiomas indicates that genomic profiling can provide valuable information for differential diagnosis of subjects with multiple meningiomas and for considering the risk for tumor occurrence in their family members.

AB Signalling actions of extracellular nucleotides via P2 receptors influence cellular function in most tissues. In the inner ear, P2 receptor signaling is involved in many processes including the regulation of hearing sensitivity and the cochlea's response to noise stress. CD39 (NTPDase1/ENTPD1) is an ectonucleotidase (ecto-nucleoside triphosphate diphosphohydrolase) that can hydrolyse purine and pyrimidine nucleoside tri- and di-phosphates to generate monophosphate nucleosides. Mice null for Cd39 exhibit major alterations in haemostasis and profound alterations in inflammatory and thrombotic reactions. Studies in the cochlea have suggested the involvement of purinergic-type signals that could be modulated by CD39 in regulation of cochlear blood flow and also auditory neurotransmission. This study aimed to determine the auditory phenotype of adult Cd39 null mice on the C57BL6 background. Auditory brainstem responses (ABR) and distortion product otoacoustic emissions (DPOAE) were unaffected in Cd39-deficient mice across the range of test frequencies, suggesting normal neural and outer hair cell function. Mutant mice also showed little difference to wild type mice in vulnerability to acoustic trauma. Gene expression analysis of other membrane-bound NTPDases with comparable hydrolytic activity demonstrated an up-regulation of Entpd2 and Entpd8 in the cochleae of Cd39 deficient mice. These findings suggest that Cd39 deletion alone does not adversely affect cochlear function, possibly as compensatory up-regulation of other surface located NTPDases may offset predicted alterations in cochlear homeostasis.

AB Time-averaged holograms describing the sound-induced motion of the tympanic membrane (TM) in cadaveric preparations from three mammalian species and one live ear were measured using opto-electronic holography. This technique allows rapid measurements of the magnitude of motion of the tympanic membrane surface at frequencies as high as 25 kHz. The holograms measured in response to low and middle-frequency sound stimuli are similar to previously reported time-averaged holograms. However, at higher frequencies (f > 4 kHz), our holograms reveal unique TM surface displacement patterns that consist of highly-ordered arrangements of multiple local displacement magnitude maxima, each of which is surrounded by nodal areas of low displacement magnitude. These patterns are similar to modal patterns (two-dimensional standing waves) produced by either the interaction of surface waves traveling in multiple directions or the uniform stimulation of modes of motion that are determined by the structural properties and boundary conditions of the TM. From the ratio of the displacement magnitude peaks to nodal valleys in these apparent surface waves, we estimate a Standing Wave Ratio of at least 4 that is consistent with energy reflection coefficients at the TM boundaries of at least 0.35. It is also consistent with small losses within the uniformly stimulated modal surface waves. We also estimate possible TM surface wave speeds that vary with frequency and species from 20 to 65 m/s, consistent with other estimates in the literature. The presence of standing. wave or modal phenomena has previously been intuited from measurements of TM function, but is ignored in some models of tympanic membrane function. Whether these standing waves result either from the interactions of multiple surface waves that travel along the membrane, or by uniformly excited modal displacement patterns of the entire TM surface is still to be determined.

AB Variable, diversity and joining gene segment (V(D) J) recombination assembles immunoglobulin heavy or light chain (IgH or IgL) variable region exons in developing bone marrow B cells, whereas class switch recombination (CSR) exchanges IgH constant region exons in peripheral B cells. Both processes use directed DNA double-strand breaks (DSBs) repaired by non-homologous end-joining (NHEJ). Errors in either V(D) J recombination or CSR can initiate chromosomal translocations, including oncogenic IgH locus (Igh) to c-myc (also known as Myc) translocations of peripheral B cell lymphomas. Collaboration between these processes has also been proposed to initiate translocations. However, the occurrence of V(D) J recombination in peripheral B cells is controversial. Here we show that activated NHEJ-deficient splenic B cells accumulate V(D) J-recombination-associated breaks at the lambda IgL locus (Igl), as well as CSR-associated Igh breaks, often in the same cell. Moreover, Igl and Igh breaks are frequently joined to form translocations, a phenomenon associated with specific Igh-Igl co-localization. Igh and c-myc also co-localize in these cells; correspondingly, the introduction of frequent c-myc DSBs robustly promotes Igh-c-myc translocations. Our studies show peripheral B cells that attempt secondary V(D) J recombination, and determine a role for mechanistic factors in promoting recurrent translocations in tumours.

AB Osteoblasts and endothelium constitute functional niches that support haematopoietic stem cells in mammalian bone marrow(1-3). Adult bone marrow also contains adipocytes, the number of which correlates inversely with the haematopoietic activity of the marrow. Fatty infiltration of haematopoietic red marrow follows irradiation or chemotherapy and is a diagnostic feature in biopsies from patients with marrow aplasia(4). To explore whether adipocytes influence haematopoiesis or simply fill marrow space, we compared the haematopoietic activity of distinct regions of the mouse skeleton that differ in adiposity. Here we show, by flow cytometry, colony-forming activity and competitive repopulation assay, that haematopoietic stem cells and short-term progenitors are reduced in frequency in the adipocyte-rich vertebrae of the mouse tail relative to the adipocyte-free vertebrae of the thorax. In lipoatrophic A-ZIP/F1 'fatless' mice, which are genetically incapable of forming adipocytes(5), and in mice treated with the peroxisome proliferator-activated receptor-c inhibitor bisphenol A diglycidyl ether, which inhibits adipogenesis(6), marrow engraftment after irradiation is accelerated relative to wild-type or untreated mice. These data implicate adipocytes as predominantly negative regulators of the bone-marrow microenvironment, and indicate that antagonizing marrow adipogenesis may enhance haematopoietic recovery in clinical bone-marrow transplantation.

AB Chromosomal instability (CIN) is a hallmark of many tumours and correlates with the presence of extra centrosomes(1-4). However, a direct mechanistic link between extra centrosomes and CIN has not been established. It has been proposed that extra centrosomes generate CIN by promoting multipolar anaphase, a highly abnormal division that produces three or more aneuploid daughter cells. Here we use long-term live-cell imaging to demonstrate that cells with multiple centrosomes rarely undergo multipolar cell divisions, and the progeny of these divisions are typically inviable. Thus, multipolar divisions cannot explain observed rates of CIN. In contrast, we observe that CIN cells with extra centrosomes routinely undergo bipolar cell divisions, but display a significantly increased frequency of lagging chromosomes during anaphase. To define the mechanism underlying this mitotic defect, we generated cells that differ only in their centrosome number. We demonstrate that extra centrosomes alone are sufficient to promote chromosome missegregation during bipolar cell division. These segregation errors are a consequence of cells passing through a transient 'multipolar spindle intermediate' in which merotelic kinetochore-microtubule attachment errors accumulate before centrosome clustering and anaphase. These findings provide a direct mechanistic link between extra centrosomes and CIN, two common characteristics of solid tumours. We propose that this mechanism may be a common underlying cause of CIN in human cancer.

AB Molecular cancer therapy relies on interstitial diffusion for drug distribution in solid tumors. A mechanistic understanding of how tumor components affect diffusion is necessary to advance cancer drug development. Yet, because of limitations in current techniques, it is unclear how individual tissue components hinder diffusion. We developed multiscale fluorescence recovery after photobleaching (MS-FRAP) to address this deficiency. Diffusion measurements facilitated by MS-FRAP distinguish the diffusive hindrance of the interstitial versus cellular constituents in living tissue. Using multiscale diffusion measurements in vivo, we resolved the contributions of these two major tissue components toward impeding diffusive transport in solid tumors and subcutaneous tissue in mice. We further used MS-FRAP in interstitial matrix-mimetic gels and in vivo to show the influence of physical interactions between collagen and hyaluronan on diffusive hindrance through the interstitium. Through these studies, we show that interstitial hyaluronan paradoxically improves diffusion and that reducing cellularity enhances diffusive macromolecular transport in solid tumors.

AB Background: We assessed the degree to which differences in guideline-based medical therapy for acute myocardial infarction (AMI) contribute to the higher mortality associated with kidney disease.
Methods: In the PREMIER registry, we evaluated patients from 19 US centers surviving AMI. Cox regression evaluated the association between estimated glomerular filtration rate (GFR) and time to death over two years, adjusting for demographic and clinical variables. The contribution of variation in guideline-based medical therapy to differences in mortality was then assessed by evaluating the incremental change in the hazard ratios after further adjustment for therapy.
Results: Of 2426 patients, 26% had GFR >= 90, 44% had GFR = 60- < 90, 22% had GFR = 30- < 60, and 8% had GFR < 30 ml/min/1.73 m(2). Greater degrees of renal dysfunction were associated with greater 2-year mortality and lower rates of guideline-based therapy among eligible patients. For patients with severely decreased GFR, adjustment for differences in guideline-based therapy did not significantly attenuate the relationship with mortality (HR 3.82, 95% CI 2.39-6.11 partially adjusted; HR = 3.90, 95% CI 2.42-6.28 after adjustment for treatment differences).
Conclusion: Higher mortality associated with reduced GFR after AMI is not accounted for by differences in treatment factors, underscoring the need for novel therapies specifically targeting the pathophysiological abnormalities associated with kidney dysfunction to improve survival.

AB Age is associated with substantial macrostructural brain changes. While some recent magnetic resonance imaging studies have reported larger age effects in men than women, others find no sex differences. As brain morphometry is a potentially important tool in diagnosis and monitoring of age-related neurological diseases, e.g., Alzheimer's disease (AD), it is important to know whether sex influences brain aging. We analyzed cross-sectional magnetic resonance scans from 1143 healthy participants from seven subsamples provided by four independent research groups. In addition, 96 patients with mild AD were included. Estimates of cortical thickness continuously across the brain surface, as well as volume of 17 subcortical structures, were obtained by use of automated segmentation tools (FreeSurfer). In the healthy participants, no differences in aging slopes between women and men were found in any part of the cortex. Pallidum corrected for intracranial volume showed slightly higher age correlations for men. The analyses were repeated in each of the seven subsamples, and the lack of age x sex interactions was largely replicated. Analyses of the AD sample showed no interactions between sex and age for any brain region. We conclude that sex has negligible effects on the age slope of brain volumes both in healthy participants and in AD.

AB The post-treatment effects of the selective cyclooxygenase (COX)-2 inhibitor, valdecoxib, were investigated in a rat model of temporary focal ischemia. Valdecoxib reduced basal brain prostaglandin E(2) concentrations at dosages that did not affect serum thromboxane B(2), consistent with a selective COX-2 effect. Temporary focal cerebral ischemia was produced in rats by middle cerebral artery occlusion for 90 min. There was increased expression of COX-2 protein detected by Western blot and immunocytochemistry within neurons in the ischemic cortex at 4 and 24 h after ischemia. Rats were treated with vehicle or valdecoxib IS min before or 1.5, 3 and 6 h after cerebral ischemia. Rats were sacrificed and brain infarction volume determined 24 h after ischemia. Valdecoxib treatment was associated with a decrease in infarction volume when administered 15 min before, and 1.5 or 3 h but not 6 h after cerebral ischemia, There were no differences in physiological parameters during the procedure. Valdecoxib administered at 1.5 h after ischemia significantly reduced the concentrations of prostaglandin E(2) in ischemic penumbral cortex as compared to the vehicle-treated group and contralateral non-ischemic cortex. These results suggest that COX-2 inhibition with valdecoxib is effective when initiated both before and after middle cerebral artery occlusion. Published by Elsevier B.V.

AB Dysregulation of the phosphatidylinositol 3-kinase (PI3K) signaling pathway occurs frequently in human cancer. PTEN tumor suppressor or PIK3CA oncogene mutations both direct PI3K-dependent tumorigenesis largely through activation of the AKT/PKB kinase. However, here we show through phosphoprotein profiling and functional genomic studies that many PIK3CA mutant cancer cell lines and human breast tumors exhibit only minimal AKT activation and a diminished reliance on AKT for anchorage-independent growth. Instead, these cells retain robust PDK1 activation and membrane localization and exhibit dependency on the PDK1 substrate SGK3. SGK3 undergoes PI3K- and PDK1-dependent activation in PIK3CA mutant cancer cells. Thus, PI3K may promote cancer through both AKT-dependent and AKT-independent mechanisms. Knowledge of differential PI3K/PDK1 signaling could inform rational therapeutics in cancers harboring PIK3CA mutations.

AB Loss-of-function mutations in the NF1 tumor suppressor result in deregulated Ras signaling and drive tumorigenesis in the familial cancer syndrome neurofibromatosis type I. However, the extent to which NF1 inactivation promotes sporadic tumorigenesis is unknown. Here we report that NF1 is inactivated in sporadic gliomas via two mechanisms: excessive proteasomal degradation and genetic loss. NF1 protein destabilization is triggered by the hyperactivation of protein kinase C (PKC) and confers sensitivity to PKC inhibitors. However, complete genetic loss, which only occurs when p53 is inactivated, mediates sensitivity to mTOR inhibitors. These studies reveal an expanding role for NF1 inactivation in sporadic gliomagenesis and illustrate how different mechanisms of inactivation are utilized in genetically distinct tumors, which consequently impacts therapeutic sensitivity.

AB Background-Electric isolation of the pulmonary veins (PVs) can successfully treat patients with paroxysmal atrial fibrillation. However, it remains technically challenging to identify the left atrial-PV junction and sequentially position the ablation catheter in a point-by-point contiguous fashion to isolate the PVs. In this study, a novel endoscopic ablation system was used to directly visualize and ablate tissue at the left atrial-PV junction with laser energy.
Methods and Results-This study consisted of 2 phases: a short-term (n = 9) and long-term (n = 11) canine experimental validation phase and a multicenter clinical feasibility phase (n = 30 paroxysmal atrial fibrillation patients). After transseptal puncture, the balloon-based endoscopic ablation system was advanced to each PV ostium, and arcs of laser energy (90 to 360) were projected onto the target left atrial-PV junction. Electric PV isolation was defined with a circular multielectrode catheter. In the short-term preclinical experimental phase, 15 of 17 targeted PVs (88%) were successfully isolated. Pathological examination revealed well-demarcated circumferential lesions with minimal endothelial disruption. In the long-term experiments, 9 of 10 targeted veins (90%) remained persistently isolated (at 4 to 8 weeks). In the clinical phase, 105 of 116 PVs (91%) were successfully isolated. After a single procedure, the 12-month drug-free rate of freedom from atrial fibrillation was 60% (18 of 30 patients). There were no significant PV stenoses, but adverse events included 1 episode of cardiac tamponade, 1 stroke without residual defect, and 1 asymptomatic phrenic nerve palsy.
Conclusion-This study establishes the feasibility of a novel paradigm for AF ablation: direct visualization to guide catheter ablation of the left atrial-PV junction. (Circulation. 2009; 120: 12-20.)

AB Background: Six candidate gene studies report a genetic association of DNA variants within the paraoxonase locus with sporadic amyotrophic lateral sclerosis (ALS). However, several other large studies, including five genome-wide association studies, have not duplicated this finding.
Methods: We conducted a meta-analysis of 10 published studies and one unpublished study of the paraoxonase locus, encompassing 4,037 ALS cases and 4,609 controls, including genome-wide association data from 2,018 ALS cases and 2,425 controls.
Results: The combined fixed effects odds ratio (OR) for rs662(PON1Q192R) was 1.09(95% confidence interval [CI], 1.02-1.16, p = 0.01); the genotypic OR for RR homozygotes at Q192R was 1.25 (95% CI, 1.07-1.45, p = 0.0004); the combined OR for rs854560(PON1L55M) was 0.97(95% CI, 0.86-1.10, p = 0.62); the OR for rs10487132 (PON2) was 1.08 (95% CI, 0.92-1.27, p = 0.35). Although the rs662 polymorphism reached a nominal level of significance, no polymorphism was significant after multiple testing correction. In the subanalysis of samples with genome-wide data from which population outliers were removed, rs662 had an OR of 1.06 (95% CI, 0.97-1.16, p = 0.22).
Conclusions: In contrast to previous positive smaller studies, our genetic meta-analysis showed no significant association of amyotrophic lateral sclerosis (ALS) with the PON locus. This is the largest meta-analysis of a candidate gene in ALS to date and the first ALS meta-analysis to include data from whole genome association studies. The findings reinforce the need for much larger and more collaborative investigations of the genetic determinants of ALS. Neurology (R) 2009; 73: 16-24

TI Monte Carlo modeling of cascade gamma rays in Y-86 PET imaging:
preliminary results
SO PHYSICS IN MEDICINE AND BIOLOGY

DT Article
ID YTTRIUM-86; RADIATION; I-124; BR-76; 2D
AB Y-86 is a PET agent that could be used as an ideal surrogate to allow personalized dosimetry in Y-90 radionuclide therapy. However, Y-86 also emits cascade gamma rays. We have developed a Monte Carlo program based on SimSET (Simulation System for Emission Tomography) to model cascade gamma rays in PET imaging. The new simulation was validated with the GATE simulation package. Agreements within 15% were found in spatial resolution, apparent scatter fraction (ratio of coincidences outside peak regions in line source sinograms), single and coincidence statistics and detected photons energy distribution within the PET energy window. A discrepancy of 20% was observed in the absolute scatter fraction, likely caused by differences in the tracking of higher energy cascade gamma photons. On average, the new simulation is 6 times faster than GATE, and the computing time can be further improved by using variance reduction techniques currently available in SimSET. Comparison with phantom acquisitions showed agreements in spatial resolutions and the general shape of projection profiles; however, the standard scatter correction method on the scanner is not directly applicable to Y-86 PET as it leads to incorrect scatter fractions. The new simulation was used to characterize Y-86 PET. Compared with conventional F-18 PET, in which major contamination at low count rates comes from scattered events, cascade gamma-involved events are more important in Y-86 PET. The two types of contaminations have completely different distribution patterns, which should be considered for the corrections of their effects. Our approach will be further improved in the future in the modeling of random coincidences and tracking of high-energy photons, and simulation results will be used for the development of correction methods in Y-86 PET.

AB Peutz-Jeghers syndrome (PJS) is a familial cancer disorder due to inherited loss of function mutations in the LKB1/STK11 serine/threonine kinase. PJS patients develop gastrointestinal hamartomas with 100% penetrance often in the second decade of life, and demonstrate an increased predisposition toward the development of a number of additional malignancies. Among mitogenic signaling pathways, the mammalian-target of rapamycin complex 1 (mTORC1) pathway is hyperactivated in tissues and tumors derived from LKB1-deficient mice. Consistent with a central role for mTORC1 in these tumors, rapamycin as a single agent results in a dramatic suppression of preexisting GI polyps in LKB1+/- mice. However, the key targets of mTORC1 in LKB1-deficient tumors remain unknown. We demonstrate here that these polyps, and LKB1- and AMPK-deficient mouse embryonic fibroblasts, show dramatic up-regulation of the HIF-1 alpha transcription factor and its downstream transcriptional targets in an rapamycin-suppressible manner. The HIF-1 alpha targets hexokinase II and Glut1 are up-regulated in these polyps, and using FDG-PET, we demonstrate that LKB1+/- mice show increased glucose utilization in focal regions of their GI tract corresponding to these gastrointestinal hamartomas. Importantly, we demonstrate that polyps from human Peutz-Jeghers patients similarly exhibit up-regulated mTORC1 signaling, HIF-1 alpha, and GLUT1 levels. Furthermore, like HIF-1 alpha and its target genes, the FDG-PET signal in the GI tract of these mice is abolished by rapamycin treatment. These findings suggest a number of therapeutic modalities for the treatment and detection of hamartomas in PJS patients, and potential for the screening and treatment of the 30% of sporadic human lung cancers bearing LKB1 mutations.

AB Docosahexaenoic acid (DHA), an n-3 long chain polyunsaturated fatty acid (LC-PUFA), highly enriched in the central nervous system, is critical for brain development and function. It has been shown that DHA deficiency impairs cognitive performance whereas DHA supplementation improves the condition. However, the mechanisms underlying the role of DHA in brain development and function remain to be elucidated. By using transgenic fat-1 mice rich in endogenous n-3 PUFA, we show that increased brain DHA significantly enhances hippocampal neurogenesis shown by an increased number of proliferating neurons and neuritogenesis, evidenced by increased density of dendritic spines of CA1 pyramidal neurons in the hippocampus. Concurrently, fat-1 mice exhibit a better spatial learning performance in the Morris water maze compared with control WT littermates. In vitro experiments further demonstrate that DHA promotes differentiation and neurite outgrowth of neuronal cells derived from mouse ES cells and increases the proliferation of cells undergoing differentiation into neuronal lineages from the ES cells. These results together provide direct evidence for a promoting effect of DHA on neurogenesis and neuritogenesis and suggest that this effect may be a mechanism underlying its beneficial effect on behavioral performance.

AB AIM: To identify a cost-effective strategy of second primary colorectal cancer (CRC) screening for cancer survivors in Korea using a decision-analytic model.
METHODS: A Markov model estimated the clinical and economic consequences of a simulated 50-year-old male cancer survivors' cohort, and we compared the results of eight screening strategies: no screening, fecal occult blood test (FOBT) annually, FOBT every 2 years, sigmoidoscopy every 5 years, double contrast barium enema every 5 years, and colonoscopy every 10 years (COL10), every 5 years (COL5), and every 3 years (COL3). We included only direct medical costs, and our main outcome measures were discounted lifetime costs, life expectancy, and incremental cost-effectiveness ratio (ICER).
RESULTS: In the base-case analysis, the non-dominated strategies in cancer survivors were COL5, and COL3. The ICER for COL3 in cancer survivors was $5593/life-year saved (LYS), and did not exceed $10000/LYS in one-way sensitivity analyses. If the risk of CRC in cancer survivors is at least two times higher than that in the general population, COL5 had an ICER of less than $10500/LYS among both good and poor prognosis of index cancer. If the age of cancer survivors starting CRC screening was decreased to 40 years, the ICER of COL5 was less than $7400/LYS regardless of screening compliance.
CONCLUSION: Our study suggests that more strict and frequent recommendations for colonoscopy such as COL5 and COL3 could be considered as economically reasonable second primary CRC screening strategies for Korean male cancer survivors. (C) 2009 The WIG Press and Baishideng. All rights reserved.

AB Atomic force microscopy (AFM) is difficult to achieve in living mammals but is necessary for understanding mechanical properties of tissues in their native form in organisms. Here we report in vivo nanomechanical imaging of blood-vessel tissues directly in living mammalians by AFM combined with surgical operations. Nanomechanical heterogeneity of blood vessels is observed across the diverse microenvironments of the same tissues in vivo. This method is further used to measure the counteractive nanomechanical changes in real time during drug-induced vasodilation and vasoconstriction in vivo, demonstrating appealing potential in characterization of in vivo nanomechanical dynamics of native tissues.

TRICHOTILLOMANIA; FAMILY; ASSOCIATION
AB SAP90/PSD95-associated protein (SAPAP) family proteins are post-synaptic density (PSD) components that interact with other proteins to form a key scaffolding complex at excitatory (glutamatergic) synapses. A recent study found that mice with a deletion of the Sapap3 gene groomed themselves excessively, exhibited increased anxiety-like behaviors, and had cortico-striatal synaptic defects, all of which were preventable with lentiviral-mediated expression of Sapap3 in the striatum; the behavioral abnormalities were also reversible with fluoxetine. In the current study, we sought to determine whether variation within the human Sapap3 gene was associated with grooming disorders (GDs: pathologic nail biting, pathologic skin picking, and/or trichotillomania) and/or obsessive-compulsive disorder (OCD) in 383 families thoroughly phenotyped for OCD genetic studies. We conducted family-based association analyses using the FBAT and GenAssoc statistical packages. Thirty-two percent of the 1,618 participants met criteria for a GD, and 65% met criteria for OCD. Four of six SNPs were nominally associated (P < 0.05) with at least one GD (genotypic relative risks: 1.6-3.3), and all three haplotypes were nominally associated with at least one GD (permuted P < 0.05). None of the SNPs or haplotypes were significantly associated with OCD itself. We conclude that Sapap3 is a promising functional candidate gene for human GDs, though further work is necessary to confirm this preliminary evidence of association. (C) 2008 Wiley-Liss, Inc.

AB Background Rivaroxaban is an oral direct factor Xa inhibitor that has been effective in prevention of venous thromboembolism in patients undergoing elective orthopaedic surgery. However, its use after acute coronary syndromes has not been investigated. In this setting, we assessed the safety and efficacy of rivaroxaban and aimed to select the most favourable dose and dosing regimen.
Methods In this double-blind, dose-escalation, phase II study, undertaken at 297 sites in 27 countries, 3491 patients stabilised after an acute coronary syndrome were stratified on the basis of investigator decision to use aspirin only (stratum 1, n=761) or aspirin plus a thienopyridine (stratum 2, n=2730). Participants were randomised within each strata and dose tier with a block randomisation method at 1:1:1 to receive either placebo or rivaroxaban (at doses 5-20 mg) given once daily or the same total daily dose given twice daily. The primary safety endpoint was clinically significant bleeding (TIMI major, TIMI minor, or requiring medical attention); the primary efficacy endpoint was death, myocardial infarction, stroke, or severe recurrent ischaemia requiring revascularisation during 6 months. Safety analyses included all participants who received at least one dose of study drug; efficacy analyses were by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00402597.
Findings Three patients in stratum 1 and 26 in stratum 2 never received the study drug. The risk of clinically significant bleeding with rivaroxaban versus placebo increased in a dose-dependent manner (hazard ratios [HRs] 2.21 [95% Cl 1.25-3.91] for 5 mg, 3.35 [2.31-4.87] for 10 mg, 3.60 [2.32-5.58] for 15 mg, and 5.06 [3.45-7.42] for 20 mg doses; p<0.0001). Rates of the primary efficacy endpoint were 5.6% (126/2331) for rivaroxaban versus 7.0% (79/1160) for placebo (HR 0.79 [0.60-1.05], p=0.10). Rivaroxaban reduced the main secondary efficacy endpoint of death, myocardial infarction, or stroke compared with placebo (87/2331 [3.9%] vs 62/1160 [5.5%]; HR 0.69, [95% CI 0.50-0.96], p=0.0270). The most common adverse event in both groups was chest pain (248/2309 [10.7%] vs 118/1153 [10.2%]).
Interpretation The use of an oral factor Xa inhibitor in patients stabilised after an acute coronary syndrome increases bleeding in a dose-dependent manner and might reduce major ischaemic outcomes. On the basis of these observations, a phase III study of low-dose rivaroxaban as adjunctive therapy in these patients is underway.

AB The pathogenesis of Shigella requires binding to the host protein N-WASP. To examine the roles of structural conformation and phospho-regulation of N-WASP during Shigello pathogenesis, mutant N-WASP constructs predicted to result in a constitutively open conformation (L229P and L232P) or either a phospho-mimicking (Y253E) or phospho-disruptive (Y253F) Structure were constructed. Pyrene actin assays demonstrated that the N-WASP L229P and L232P constructs are Constitutively active. Despite the increase in actin polymerization seen in vitro, cell lines expressing N-WASP L229P and L232P Supported shorter actin tails when infected with Shigella. Shigella actin tails were unchanged in cells expressing N-WASP phospho-regulation mutant proteins. Shigella invasion, intracellular, and intercellular motility were not altered in cells expressing N-WASP L229P or L232P. However, plaque numbers were increased in cells expressing N-WASP L229P and L232P. These data demonstrate that N-WASP Structural conformation is an important regulator of Shigella pathogenesis in distinct segments of its lifecycle. (C) 2009 Elsevier Inc. All rights reserved

AB The induction of Rrs1 expression is one of the earliest events detected in a presymptomatic knock-in mouse model of Huntington disease (HD). Rrs1 up-regulation fulfills the HD criteria of dominance, striatal specificity, and polyglutamine dependence. Here we show that mammalian Rrs1 is localized both in the nucleolus as well as in the endoplasmic reticulum ( ER) of neurons. This dual localization is shared with its newly identified molecular partner 3D3/lyric. We then show that both genes are induced by ER stress in neurons. Interestingly, we demonstrate that ER stress is an early event in a presymptomatic HD mouse model that persists throughout the life span of the rodent. We further show that ER stress also occurs in postmortem brains of HD patients.

AB Disease alleles that activate signal transduction are common in myeloid malignancies; however, there are additional unidentified mutations that contribute to myeloid transformation. Based on the recent identification of TET2 mutations, we evaluated the mutational status of TET1, TET2, and TET3 in myeloproliferative neoplasms (MPNs), chronic myelomonocytic leukemia (CMML), and acute myeloid leukemia (AML). Sequencing of TET2 in 408 paired tumor/normal samples distinguished between 68 somatic mutations and 6 novel single nucleotide polymorphisms and identified TET2 mutations in MPN (27 of 354, 7.6%), CMML (29 of 69, 42%), AML (11 of 91, 12%), and M7 AML (1 of 28, 3.6%) samples. We did not identify somatic TET1 or TET3 mutations or TET2 promoter hypermethylation in MPNs. TET2 mutations did not cluster in genetically defined MPN, CMML, or AML subsets but were associated with decreased overall survival in AML (P = .029). These data indicate that TET2 mutations are observed in different myeloid malignancies and may be important in AML prognosis. (Blood. 2009; 114:144-147)

TI The Gene expression Grade Index: a potential predictor of relapse for

SO BMC MEDICAL GENOMICS

DT Article
ID POSTMENOPAUSAL WOMEN; ADJUVANT TAMOXIFEN; RANDOMIZED-TRIAL; LETROZOLE;
ANASTROZOLE
AB Background: We have previously shown that the Gene expression Grade Index (GGI) was able to identify two subtypes of estrogen receptor (ER)-positive tumors that were associated with statistically distinct clinical outcomes in both untreated and tamoxifen-treated patients. Here, we aim to investigate the ability of the GGI to predict relapses in postmenopausal women who were treated with tamoxifen (T) or letrozole (L) within the BIG 1-98 trial.
Methods: We generated gene expression profiles (Affymetrix) and computed the GGI for a matched, case-control sample of patients enrolled in the BIG 1-98 trial from the two hospitals where frozen samples were available. All relapses (cases) were identified from patients randomized to receive monotherapy or from the switching treatment arms for whom relapse occurred before the switch. Each case was randomly matched with four controls based upon nodal status and treatment (T or L). The prognostic value of GGI was assessed as a continuous predictor and divided at the median. Predictive accuracy of GGI was estimated using time-dependent area under the curve (AUC) of the ROC curves.
Results: Frozen samples were analyzable for 48 patients (10 cases and 38 controls). Seven of the 10 cases had been assigned to receive L. Cases and controls were comparable with respect to menopausal and nodal status, local and chemotherapy, and HER2 positivity. Cases were slightly older than controls and had a larger proportion of large, poorly differentiated ER+/PgR- tumors. The GGI was significantly and linearly related to risk of relapse: each 10-unit increase in GGI resulted in an increase of approximately 11% in the hazard rate (p = 0.02). Within the subgroups of patients with node-positive disease or who were treated with L, the hazard of relapse was significantly greater for patients with GGI at or above the median. AUC reached a maximum of 78% at 27 months.
Conclusion: This analysis supports the GGI as a good predictor of relapse for ER-positive patients, even among patients who receive L. Validation of these results, in a larger series from BIG 1-98, is planned using the simplified GGI represented by a smaller set of genes and tested by qRT-PCR on paraffin-embedded tissues.

AB The initial steps in the pathogenesis of acute leukemia remain incompletely understood. The TEL-AML1 gene fusion, the hallmark translocation in Childhood Acute Lymphoblastic Leukemia and the first hit, occurs years before the clinical disease, most often in utero. We have generated mice in which TEL-AML1 expression is driven from the endogenous promoter and can be targeted to specific populations. TEL-AML1 renders mice prone to malignancy after chemical mutagenesis when expressed in hematopoietic stem cells (HSCs), but not in early lymphoid progenitors. We reveal that TEL-AML1 markedly increases the number of HSCs and predominantly maintains them in the quiescent (Go) stage of the cell cycle. TEL-AML1(+) HSCs retain self-renewal properties and contribute to hematopoiesis, but fail to out-compete normal HSCs. Our work shows that stem cells are susceptible to subversion by weak oncogenes that can subtly alter their molecular program to provide a latent reservoir for the accumulation of further mutations.

AB We report here homologous recombination (HR)-mediated gene targeting of two different genes in human PS cells (hiPSCs) and human ES cells (hESCs). HR-mediated correction of a chromosomally integrated mutant GFP reporter gene reaches efficiencies of 0.14%-0.24% in both cell types transfected by donor DNA with plasmids expressing zinc finger nucleases (ZFNs). Engineered ZFNs that induce a sequence-specific double-strand break in the GFP gene enhanced HR-mediated correction by > 1400-fold without detectable alterations in stem cell karyotypes or pluripotency. Efficient HR-mediated insertional mutagenesis was also achieved at the endogenous PIG-A locus, with a > 200-fold enhancement by ZFNs targeted to that gene. Clonal PIG-A null hESCs and iPSCs with normal karyotypes were readily obtained. The phenotypic and biological defects were rescued by PIG-A transgene expression. Our study provides the first demonstration of HR-mediated gene targeting in hiPSCs and shows the power of ZFNs for inducing specific genetic modifications in hiPSCs, as well as hESCs.

AB The generation and expansion of diverse cardiovascular cell lineages is a critical step during human cardiogenesis, with major implications for congenital heart disease. Unravelling the mechanisms for the diversification of human heart cell lineages has been hampered by the lack of genetic tools to purify early cardiac progenitors and define their developmental potential(1-4). Recent studies in the mouse embryo have identified a multipotent cardiac progenitor that contributes to all of the major cell types in the murine heart(5-8). In contrast to murine development, human cardiogenesis has a much longer onset of heart cell lineage diversification and expansion, suggesting divergent pathways. Here we identify a diverse set of human fetal ISL1(+) cardiovascular progenitors that give rise to the cardiomyocyte, smooth muscle and endothelial cell lineages. Using two independent transgenic and gene-targeting approaches in human embryonic stem cell lines, we show that purified ISL1(+) primordial progenitors are capable of self-renewal and expansion before differentiation into the three major cell types in the heart. These results lay the foundation for the generation of human model systems for cardiovascular disease and novel approaches for human regenerative cardiovascular medicine.

AB Pluripotency of embryonic stem (ES) cells is controlled by defined transcription factors(1,2). During differentiation, mouse ES cells undergo global epigenetic reprogramming, as exemplified by X-chromosome inactivation (XCI) in which one female X chromosome is silenced to achieve gene dosage parity between the sexes(3-5). Somatic XCI is regulated by homologous X-chromosome pairing(6,7) and counting(8-10), and by the random choice of future active and inactive X chromosomes. XCI and cell differentiation are tightly coupled(11), as blocking one process compromises the other(8,12) and dedifferentiation of somatic cells to induced pluripotent stem cells is accompanied by X chromosome reactivation(2). Recent evidence suggests coupling of Xist expression to pluripotency factors occurs(13), but how the two are interconnected remains unknown. Here we show that Oct4 (also known as Pou5f1)(14) lies at the top of the XCI hierarchy, and regulates XCI by triggering X-chromosome pairing and counting. Oct4 directly binds Tsix and Xite, two regulatory noncoding RNA genes of the X-inactivation centre(15,16), and also complexes with XCI trans-factors, Ctcf and Yy1 (ref. 17), through protein-protein interactions. Depletion of Oct4 blocks homologous X-chromosome pairing and results in the inactivation of both X chromosomes in female cells. Thus, we have identified the first trans-factor that regulates counting, and ascribed new functions to Oct4 during X-chromosome reprogramming.

AB Background: Emergency departments (EDs) are traditionally designed to provide rapid evaluation and stabilization and are neither staffed nor equipped to provide prolonged care. Longer ED length of stay (LOS) may compromise quality of care and contribute to delays in the emergency evaluation of other patients.
Objectives: The objective was to determine whether ED LOS increased between 2001 and 2005 and whether trends varied by patient and hospital factors.
Methods: This was a retrospective analysis of a nationally representative sample of 138,569 adult ED visits from the National Hospital Ambulatory Medical Care Survey (NHAMCS), 2001 to 2005. ED LOS was measured from registration to discharge. Results: Median ED LOS increased 3.5% per year from 132 minutes in 2001 to 154 minutes in 2005 (p-value for trend < 0.001). There was a larger increase among critically ill patients for whom ED LOS increased 7.0% annually from 185 minutes in 2001 to 254 minutes in 2005 (p-value for trend < 0.01). ED LOS was persistently longer for black/African American, non-Hispanic patients (10.6% longer) and Hispanic patients (13.9% longer) than for non-Hispanic white patients, and these differences did not diminish over time. Among factors potentially associated with increasing ED LOS, a large increase was found (60.1%, p-value for trend < 0.001) in the use of advanced diagnostic imaging (computed tomography [CT], magnetic resonance imaging [MR], and ultrasound [US]) and in the proportion of ED visits at which five or more diagnostic or screening tests were ordered (17.6% increase, p-value for trend = 0.001). The proportion of uninsured patients was stable throughout the study period, and EDs with predominately privately insured patients experienced significant increases in ED LOS (4.0% per year from 2001 to 2005, p-value for trend < 0.01).
Conclusions: Emergency department LOS in the United States is increasing, especially for critically ill patients for whom time-sensitive interventions are most important. The disparity of longer ED LOS for African Americans and Hispanics is not improving. ACADEMIC EMERGENCY MEDICINE 2009; 16:609-616 (c) 2009 by the Society for Academic Emergency Medicine

AB Objectives: There is limited information on the financial implications of an emergency department ultrasound (ED US) program. The authors sought to perform a fiscal analysis of an integrated ED US program.
Methods: A retrospective review of billing data was performed for fiscal year (FY) 2007 for an urban academic ED with an ED US program. The ED had an annual census of 80,000 visits and 1,101 ED trauma activations. The ED is a core teaching site for a 4-year emergency medicine (EM) residency, has 35 faculty members, and has 24-hour availability of all radiology services including formal US. ED US is utilized as part of evaluation of all trauma activations and for ED procedures. As actual billing charges and reimbursement rates are institution-specific and proprietary information, relative value units (RVUs) and reimbursement based on the Centers for Medicare & Medicaid Services (CMS) 2007 fee schedule (adjusted for fixed diagnosis-related group [DRG] payments and bad debt) was used to determine revenue generated from ED US. To estimate potential volume, assumptions were made on improvement in documentation rate for diagnostic scans (current documentation rates based on billed volume versus diagnostic studies in diagnostic image database), with no improvements assumed for procedural ED US. Expenses consist of three components-capital costs, training costs, and ongoing operational costs-and were determined by institutional experience. Training costs were considered sunken expenses by this institution and were thus not included in the original return on investment (ROI) calculation, although for this article a second ROI calculation was done with training cost estimates included. For the purposes of analysis, certain key assumptions were made. We utilized a collection rate of 45% and hospitalization rates (used to adjust for fixed DRG payments) of 33% for all diagnostic scans, 100% for vascular access, and 10% for needle placement. An optimal documentation rate of 95% was used to estimate potential revenue.
Results: In FY 2007, 486 limited echo exams of abdomen (current procedural terminology [CPT] 76705) and 480 limited echo cardiac exams were performed (CPT 93308) while there were 78 exams for US-guided vascular access (CPT 76937) and 36 US-guided needle placements when performing paracentesis, thoracentesis, or location of abscess for drainage (CPT 76492). Applying the 2007 CMS fee schedule and above assumptions, the revenue generated was 578 RVUs and $35,541 ($12,934 in professional physician fees and $22,607 in facility fees). Assuming optimal documentation rates for diagnostic ED US scans, ED US could have generated 1,487 RVUs and $94,593 ($33,953 in professional physician fees and $60,640 in facility fees). Program expenses include an initial capital expense (estimated at $120,000 for two US machines) and ongoing operational costs ($68,640 per year to cover image quality assurance review, continuing education, and program maintenance). Based on current revenue, there would be an annual operating loss, and thus an ROI cannot be calculated. However, if potential revenue is achieved, the annual operating income will be $22,846 per year with an ROI of 4.9 years to break even with initial investment.
Conclusions: Determining an ROI is a required procedure for any business plan for establishing an ED US program. Our analysis demonstrates that an ED US program that captures charges for trauma and procedural US and achieves the potential billing volume breaks even in less than 5 years, at which point it would generate a positive margin.

AB Purpose
To identify common struggles of interns, determine residency program directors' (PDs') views of the competencies to be gained in the fourth year of medical school, and apply this information to formulate goals of curricular reform and student advising.
Method
In 2007, semistructured interviews were conducted with 30 PDs in the 10 most common specialty choices of students the University of California, San Francisco, School of Medicine to assess the PDs' priorities for knowledge, skills, and attitudes to be acquired in the fourth year. Interviews were coded to identify major themes.
Results
Common struggles of interns were lack of self-reflection and improvement, poor organizational skills, underdeveloped professionalism, and lack of medical knowledge. The Accreditation Council for Graduate Medical Education competencies of patient care, practice-based learning and improvement, interpersonal and communication skills, and professionalism were deemed fundamental to fourth-year students' development. Rotations recommended across specialties were a subinternship in a student's future field and in internal medicine (IM), rotations in an IM subspecialty, critical care, and emergency and ambulatory medicine. PDs encouraged minimizing additional time spent in the student's future field. Suggested coursework included an intensively coached transitional subinternship and courses to improve students' medical knowledge.
Conclusions
PDs deemed the fourth year to have a critical role in the curriculum. There was consensus about expected fourth-year competencies and the common clinical experiences that best prepare students for residency training. These findings support using the fourth year to transition students to graduate medical training and highlight areas for curricular innovation.

AB Objective.-There are many studies of the Pediatric Symptom Checklist (PSC), but none has followed a naturalistic sample longitudinally. We aimed to examine persistence and change in PSC scores over time in children seen in an ambulatory pediatric setting.
Methods.-The sample of 1033 patients was PSC screened at 2 consecutive preventive care visits (10 to 18 months apart) in 2 pediatric clinics. Longitudinal analyses were conducted to assess predictors of change in PSC category and score.
Results.-Approximately 30% of the initially screened population did not return for preventive pediatric care. Those who did not return were significantly more likely to have positive PSC scores than those who returned (8% compared with 4.3%, P < .01). PSC scores were highly stable at visit 2 for those who initially scored negative, but they fluctuated more for those who initially scored positive. After controlling for sociodemographic variables and counseling at either visit, referral at visit 1 (P < .0001) predicted changes in mean PSC scores at visit 2. On average, PSC score decreased 3.2 points among those referred at visit 1 but increased 1.6 points in nonreferred children.
Conclusions.-This is the first study to document the stability and change in PSC scores in a sample of ambulatory pediatric patients. The statistically significant association between pediatrician referral and improved PSC scores provides evidence for the value of referral in primary care, although the study did not examine the relationship between PSC screening and referral. The high rate of positive scores in children who did not return for follow-up suggests the need for alternative strategies for this population.

VIRTUAL COLONOSCOPY; CONTRAST-MEDIUM; TRIAL; FEASIBILITY
AB Rationale and Objectives. To compare prospectively 64-detector-row computed tomographic colonography (CTC) after a full-laxative tagging-based preparation (full preparation) with a minimum-laxative tagging-based preparation (minimum preparation) with respect to diagnostic performance in the detection of polyps, tagging quality, and patient acceptance.
Materials and Methods. Consecutive 10 1 patients at high risk for developing colorectal cancer were alternately assigned to either a full preparation group (n = 51) or a minimum preparation group (n = 50) for fecal-tagging CTC. The full preparation consisted of administration of 2-L polyethylene glycol solution with 20 mL of sodium diatrizoate for fecal tagging. The minimum preparation consisted of ingestion of a total of 45 mL of sodium diatrizoate during the 3 days before and 1 0 mL of sodium picosulfate solution the night before CT. Colonoscopy was used as the reference standard. We assessed the accuracy of polyp detection and the tagging quality for each preparation. All patients were given questionnaires related to their acceptance.
Results. Per-patient sensitivity, specificity, and positive and negative predictive values for polyps >= 6 mm were as follows: full preparation group, 97%, 92%, 88%, and 98%, respectively; minimum preparation group, 88%, 68%, 56%, and 92%, respectively. Average visual subjective tagging scores for the full and minimum preparation groups were 94.6% and 76.1%, respectively (P < .0001). Minimum preparation was better tolerated than full preparation.
Conclusion. Although full-laxative and minimum-laxative fecal-tagging CTC yielded an equally high sensitivity in the detection of polyps >= 6 min, the full-laxative fecal-tagging CTC yielded a better specificity than did the minimum-laxative fecal-tagging CTC. Thus, it is desirable to offer patients an option of either full-laxative fecal-tagging CTC for highest diagnostic accuracy and ability to perforin a same-day therapeutic colonoscopy without additional bowel preparation, or minimum-laxative fecal-tagging CTC for those unwilling to undergo full preparation but willing to accept moderate decrease in specificity.

AB Magnetic resonance imaging (MRI) is a powerful medical diagnostic technique: it can penetrate deep into tissue, provide excellent soft tissue contrast with sub-millimeter resolution, and does not employ ionizing radiation. Targeted contrast agents provide an additional layer of molecular specificity to the wealth of anatomical and functional information already attainable by MRI. However, the major challenge for molecular MR imaging is sensitivity: micromolar concentrations of Gd-III are required to cause a detectable signal change, which makes detecting proteins by MR[ a challenge.
Protein-targeted MRI contrast agents are bifunctional molecules comprising a protein-targeting moiety and typically one or more gadolinium chelates for detection by MRI. The ability of the contrast agent to enhance the MR image is termed relaxivity, and it depends upon many molecular factors, including protein binding itself. As in other imaging modalities, protein binding provides the pharmacokinetic effect of concentrating the agent at the region of interest. Unique to MRI, protein binding provides the pharmacodynamic effect of increasing the relaxivity of the contrast agent, thereby increasing the MR signal. In designing new agents, optimization of both the targeting function and the relaxivity is critical.
In this Account, we focus on optimization of the relaxivity of targeted agents. Relaxivity depends upon speciation, chemical structure, and dynamic processes, such as water exchange kinetics and rotational tumbling rates. We describe mechanistic studies that relate these factors to the observed relaxivities and use these findings as the basis of rational design of improved agents. In addition to traditional biochemical methods to characterize ligand-protein interactions, the presence of the metal ion enables more obscure biophysical techniques, such as relaxometry and electron nuclear double resonance, to be used to elucidate the mechanism of relaxivity differences.
As a case study, we explore the mechanism of action of the serum-albumin-targeted angiography agent MS-325 and closely related compounds and show how small changes in the metal chelate can impact relaxivity. We found that, while protein binding generally improves relaxivity by slowing the tumbling rate of the complex, in some cases, the protein itself can also negatively affect hydration of the metal complex and/or inner-sphere water exchange. Drawing on these findings, we designed next-generation agents targeting albumin, fibrin, or collagen and incorporating up to four gadolinium chelates. Through judicious molecular design, we show that high-relaxivity complexes with high target affinity can be realized.

AB The nematode Coenorhabditis elegons is a unique whole animal model system for identifying small molecules with in vivo anti-infective properties. C elegons can be infected with a broad range of human pathogens, including Enterococcus faecalis, an important human nosocomial pathogen. Here, we describe an automated, high-throughput screen of 37,200 compounds and natural product extracts for those that enhance survival of C elegans infected with E faecalis. Using a robot to dispense live, infected animals into 384-well plates and automated microscopy and image analysis, we identified 28 compounds and extracts not previously reported to have antimicrobial properties, including six structural classes that cure infected C elegons animals but do not affect the growth of the pathogen in vitro, thus acting by a mechanism of action distinct from antibiotics currently in clinical use.

TI A survey of tobacco dependence treatment guidelines in 31 countries

DE Tobacco dependence treatment; national treatment guidelines; survey
ID TREATMENT SERVICES
AB The Framework Convention on Tobacco Control (FCTC) asks countries to develop and disseminate comprehensive evidence-based guidelines and promote adequate treatment for tobacco dependence, yet to date no summary of the content of existing guidelines exists. This paper describes the national tobacco dependence treatment guidelines of 31 countries.
A questionnaire on tobacco dependence treatment guidelines was sent by e-mail to a convenience sample of contacts working in tobacco control in 31 countries in 2007. Completed questionnaires were received from respondents in all 31 countries. During the course of these enquiries we also made contact with people in 14 countries that did not have treatment guidelines and sent them a short questionnaire asking about their plans to produce guidelines.
The survey instrument was a 17-item questionnaire asking the following key questions: do the guidelines recommend brief interventions, intensive behavioural support, medications; which medications; do the guidelines apply to the whole health-care system and all professionals; do they refer explicitly to the Cochrane database; are they based on another country's guidelines; are they national or more local; are they endorsed formally by government; did they undergo peer review; who funded them; where were they published; do they include evidence on cost effectiveness of treatment?
According to respondents, all their countries' guidelines recommended brief advice, intensive behavioural support and nicotine replacement therapy (NRT); 84% recommended bupropion; 19% recommended varenicline; and 35% recommended telephone quitlines. Nearly half (48%) included cost-effectiveness evidence. Seventy-one per cent were supported formally by their government and 65% were supported financially by the government. Most (84%) used the Cochrane reviews as a source of evidence, 84% underwent a peer review process and 55% were based on the guidelines of other countries, most often the United States and England.
Overall, the guidelines reviewed followed the evidence base closely, recommending brief interventions, intensive behavioural support and NRT, and most recommended bupropion. Varenicline was not on the market in most of the countries in this survey when their guidelines were written, illustrating the need for guidelines to be updated periodically. None recommended interventions not proven to be effective, and some recommended explicitly against specific interventions (for lack of evidence). Most were peer-reviewed, many through lengthy and rigorous procedures, and most were endorsed or supported formally by their governments. Some countries that did not have guidelines expressed a need for technical support, emphasizing the need for countries to share experience, something the FCTC process is well placed to support.

AB Bridge of bone canthopexy has utility when significant movements of canthal position are required. It is a technique whereby the lateral canthal structures are purchased with a figure-of-eight suture of titanium wire. Drill holes are placed in the lateral orbital rim using the zygomaticofrontal sutures as reference landmarks. A canthal fixation point (the inferior drill hole) creates a measured distance from a fixed anatomic point (the zygomaticofrontal suture) assuring accurate and symmetric canthus positioning. Wire suture fixation over the bridge of bone created by the two drill holes provides maximum stability to counter soft tissue deforming forces. Fine adjustments can be made to the canthal position by twisting or untwisting the wire ends. (Aesthetic Surg J 2009;29:323-329.)

AB We evaluated the association of alcohol consumption and depression, and their effects on HIV disease progression among women with HIV. The study included 871 women with HIV who were recruited from 19931995 in four US cities. The participants had physical examination, medical record extraction, and venipuncture, CD4+ T-cell Counts determination, measurement of depression symptoms (using the self-report Center for Epidemiological Studies-Depression Scale), and alcohol use assessment at enrollment, and semiannually until March 2000. Multilevel random coefficient ordinal models as well as multilevel models with joint responses were used in the analysis. There was no significant association between level of alcohol use and CD4+ T-cell counts. When participants were stratified by antiretroviral therapy (ART) Use. the association between alcohol and CD4+ T-cell did not reach statistical significance. The association between alcohol consumption and depression was significant (p < 0.001). Depression had a significant negative effect on CD4+ T-cell counts over time regardless of ART use. Our findings Suggest that alcohol consumption has a direct association with depression, Moreover, depression is associated with HIV disease progression. Our findings have implications for the provision of alcohol use interventions and psychological resources to improve the health of women with HIV.

AB Men who have sex with men (MSM) continue to bear a disproportionate HIV and sexually transmitted disease (STD) burden. The current study examined the frequency and associations of sexual risk reduction behaviors among a sample of MSM in the greater Boston, Massachusetts area. One hundred eighty-nine MSM completed a one-time behavioral and psychosocial assessment between March 2006 and May 2007. Logistic regression procedures examined the association of demographic, psychosocial, and behavioral factors with risk reduction practices. Twenty percent of the sample reported rimming, mutual masturbation, digital penetration, using sex toys, or 100% condom use as a means to reduce their risk of acquiring or transmitting HIV in the prior 12 months. In bivariate analyses, risk reducers were more likely to disclose their MSM status (i.e., be "out''; odds ratio [OR] = 3.64; p < 0.05), and report oral sex with a condom in the prior 12 months (OR = 4.85; p < 0.01). They were less likely to report: depression (Center for Epidemiologic Studies Depression Scale [CES-D] score 16+; OR = 0.48; p < 0.05), a history of one or more sexually transmitted diseases (STDs; OR = 0.40; p < 0.05), and meeting sexual partners at public cruising areas (OR = 0.32; p < 0.01). In a multivariable model, risk reducers were less likely to report: alcohol use during sex (adjusted odds ratio [AOR] = 0.33; p < 0.05), depression (CESD score 16+; AOR = 0.32; p < 0.05), or meeting sexual partners at public cruising areas (AOR = 0.30; p < 0.05), or via the Internet (AOR = 0.12; p < 0.05) in the previous 12 months. Identifying and understanding such factors associated with risk reduction behaviors may be important to consider in designing effective prevention interventions to promote sexual health for MSM.

AB We performed a pilot randomized, controlled trial of intensive, computer-based cognitive training in 47 subjects with mild cognitive impairment. The intervention group performed exercises specifically designed to improve auditory processing speed and accuracy for 100 min/d, 5 d/wk for 6 weeks; the control group performed more passive computer activities (reading, listening, visuospatial game) for similar amounts of time. Subjects had a mean age of 74 years and 60% were men; 77% successfully completed training. On our primary outcome, Repeatable Battery for Assessment of Neuropsychological Status total scores improved 0.36 standard deviations (SD) in the intervention group (P = 0.097) compared with 0.03 SD in the control group (P = 0.88) for a nonsignificant difference between the groups of 0.33 SD (P = 0.26). On 12 secondary outcome measures, most differences between the groups were not statistically significant. However, we observed a pattern in which effect sizes for verbal learning and memory measures tended to favor the intervention group whereas effect sizes for language and visuospatial function measures tended to favor the control group, which raises the possibility that these training programs may have domain-specific effects. We conclude that intensive, computer-based mental activity is feasible in subjects with mild cognitive impairment and that larger trials are warranted.

AB Although early studies on mild cognitive impairment (MCI) focused on memory dysfunction; more recent Studies suggest that MCI is clinically heterogeneous. The objective of this study is to examine patterns of cerebral perfusion in anmestic (N = 12) and nonamnestic (N = 12) single-domain MCI patients from 4 a priori regions of interest: middle and superior frontal cortex, posterior cingulate, and precuneus, to compare them relative to healthy controls (N = 12), and to correlate perfusion with neuropsychologic measures. Relative to controls, all MCI patients had hypoperfusion in the posterior cingulate, bilaterally. MCI patients with executive dysfunctions also showed hypoperfusion in bilateral middle frontal cortex and the left precuneus relative to controls and in the left middle frontal cortex, left posterior cingulate, and left precuneus relative to amnestic MCI patients. Perfusion in the posterior cingulate correlated positively with memory performance whereas perfusion in all 4 a priori regions of interest, predominately on the left side, correlated with executive function performance. The finding that single-domain MCI patients with prominent deficits in different cognitive domains exhibited different patterns of hypoperfusion relative to controls supports the existence of distinct subgroups of MCI. These data further Suggest that cognitive impairment in MCI is related to cerebral hypoperfusion.

TI Association of Thrombolysis in Myocardial Infarction Myocardial
Perfusion Grade with cardiovascular magnetic resonance measures of
infarct architecture after primary percutaneous coronary intervention
for ST-segment elevation myocardial infarction
SO AMERICAN HEART JOURNAL
LA English
DT Article
ID MICROVASCULAR OBSTRUCTION; VENTRICULAR-TACHYCARDIA; HETEROGENEITY;
DYSFUNCTION; MORPHOLOGY; MORTALITY
AB Background Primary percutaneous coronary intervention (pPCI) routinely restores normal epicardial flow among patients with ST-segment elevation myocardial infarction (STEMI). However, impairment of myocardial perfusion frequently persists. The goal of this analysis was to determine whether impaired myocardial perfusion was associated with cardiovascular magnetic resonance-defined abnormalities in infarct architecture, including infarct size (IS), infarct surface area (ISA), infarct border zone (IBZ), and infarct complexity (IC).
Methods Thirty-one patients with STEMI treated with pPCI were included in the analysis. Cardiovascular magnetic resonance was performed within 7 days of presentation and repeated at 3 months. Infarct complexity was defined as the ratio of actual ISA to an idealized smooth ISA and normalized to IS.
Results Impaired Thrombolysis in Myocardial Infarction Myocardial Perfusion Grade (TMPG) (<3) was associated with larger ISA at baseline (78.2 +/- 25.3 cm(2) vs 40.3 +/- 30.3 cm(2), P = .02) and follow-up (58.8 +/- 27.5 cm(2) vs 26.3 +/- 20.2 cm(2), P = .03) and larger IBZ at follow-up (7.8% +/- 2.7% vs 4.1% +/- 3.3%, P = .02). At follow-up, ISA, when normalized to 15, was significantly higher among patients with impaired myocardial perfusion (TMPG <3) (6.9 +/- 2.5 vs 5.9 +/- 2.4 cm(2)/%, P = .03). Thrombolysis in MI myocardial perfusion grade <3 was also associated with increased IC at follow-up (52% +/- 12% vs 33% +/- 16%, P = .01).
Conclusions Impaired TMPG is associated with larger ISA, IBZ, and increased IC. At 3 months, TMPG remained associated with ISA and IC after adjusting for IS, suggesting that impaired TMPG after pPCI is associated with infarct architecture after healing, independent of IS.

AB Background Although prior data showed an association between chronic kidney disease (CKD) and atherothrombotic events, little is known about the risk profile and specific outcomes of atherothrombotic outpatients with CKD.
Methods More than 69,000 outpatients at risk of atherothrombotic events were enrolled in the REACH Registry. Creatinine clearance (CrCl) was available for 51,208 patients divided into A groups: normal (CrCl >= 90 mL/min, n = 13,949), mild (60-89 mL/min, n = 19,474), moderate (30-59 mL/min, n = 15,883), and severe CKD (CrCl <30 mL/min, n = 1902). Baseline characteristics, number of arterial beds overtly affected, medications, overall mortality, cardiovascular death, myocardial infarction, stroke, congestive heart failure, peripheral arterial events, and bleeding events were assessed according to renal function.
Results The number of arterial beds affected increased with severity of CKD. However, patients with severe CKD were less likely to receive medications of proven benefit. Severe CKD was an independent correlate of all-cause mortality, cardiovascular mortality, myocardial infarction, congestive heart failure, peripheral arterial revascularization, or amputation.
Conclusion One third of outpatients at risk for atherothrombotic events have moderate to severe CKD. They are less likely to receive beneficial therapies despite a higher atherothrombotic burden and worse outcomes. (Am Heart J 2009; 158:141-8.)

ID LONG-TERM PROGNOSIS; UNSTABLE ANGINA; SILENT ISCHEMIA; RISK SCORE;
INFARCTION; REPERFUSION; DEATH
AB In patients with unstable angina, evidence of myocardial ischemia on Holter monitoring is associated with an adverse prognosis. However, the association of duration and timing of ischemia on Holter monitoring with outcomes after percutaneous coronary intervention (PCI) in patients with non-ST-segment elevation acute coronary syndromes (NSTEACSs) has not been systematically evaluated. PROTECT-TIMI 30 randomized 857 patients with NSTEACSs undergoing PCI to eptifibatide plus a heparin product or bivalirudin monotherapy. Patients underwent continuous Holter monitoring following PCI, and the association between ischemia and clinical outcomes was evaluated retrospectively. Forty-three patients (5.0%) had ischemia on Holter after PCI. Any ischemia was associated with a significant increase in the incidence of death or myocardial infarction (MI) within 48 hours (32.6% vs 6.1%, odds ratio 7.S, 95% confidence interval 3.70 to 15.10, p <0.001). In patients who developed ischemia, there was a 1.44-fold increase in the odds for death or MI for every 30 minutes of ischemia (95% confidence interval 1.12 to 1.84, p = 0.004). Duration of ischemic events was related to their timing, such that ischemic events that occurred within the first 4 hours after PCI (median duration 141 minutes, interquartile range 36 to 227.5) were significantly longer than events occurring 4 to 24 hours after PCI (median duration 32.8 minutes, interquartile range 17.5 to 118, p = 0.041). In conclusion, early ischemia after PCI for NSTEACS is of longer duration, and longer duration of ischemia recognized by Holter monitoring is associated with an increased incidence of death or MI. Holter monitoring may be a useful surrogate end point in clinical trials. (c) 2009 Elsevier Inc. (Am J Cardiol 2009;104:36-40)

AB Basic and clinical studies have suggested that inflammation predisposes to atrial fibrillation (AF). We assessed the association of 12 circulating inflammatory biomarkers (i.e., C-reactive protein, fibrinogen, interleukin-6, intercellular adhesion molecule-1, lipoprotein-associated phospholipase A2 [mass and activity], monocyte chemoattractant protein-1, myelo-peroxidase, CD40 ligand, osteoprotegerin, P-selectin, and tumor necrosis factor receptor II) with incident AF in 2863 Framingham Offspring Study participants (mean age 60.7 years, SD = 9.4, 55% women). During follow-up (median 6 years), 148 participants (43% women) developed incident AF. In the multivariable proportional hazards models, the inflammatory biomarker panel was associated with incident AF (p = 0.03). With stepwise selection (p <0.01 for entry and retention), log-transformed osteoprotegerin was associated with incident AF (hazard ratio per SD 1.30, 95% confidence interval 1.08 to 1.56, p = 0.006). Adjusting for interim myocardial infarction or heart failure attenuated the association between osteoprotegerin and incident AF (hazard ratio 1.18, 95% confidence interval 0.98 to 1.43, p = 0.09). In conclusion, circulating osteoprotegerin concentration was significantly associated with incident AF in our community-based sample, possibly mediated by interim cardiovascular events.

AB Left ventricular (LV) hypertrophy is a well-established, but highly variable, finding among exercise-trained persons. The causes for the variability in LV remodeling in response to exercise training remain incompletely understood. The present study sought to determine whether a family history of hypertension is a determinant of the cardiac response to exercise training. The cardiac parameters in 60 collegiate rowers (30 men/30 women; age 19.8 +/- 1.1 years) with (family history positive [FH+], n = 22) and without (family history negative [FH-], n = 38) a FH of hypertension were studied with echocardiography before and after 90 days of rowing training. The LV mass increased significantly in both groups. However, the LV mass increased significantly more in FH- persons (Delta 17 +/- 5 g/m(2)) than in FH+ persons (Delta 9 +/- 6 g/m(2), p <0.001) with distinctly differently patterns of LV hypertrophy between the 2 groups. FH- athletes experienced eccentric LV hypertrophy (relative wall thickness index 0.39 +/- 0.4) characterized by LV dilation. In contrast, FH+ athletes developed concentric LV hypertrophy (relative wall thickness index 0.44 +/- 0.3; p <0.001) characterized by LV wall thickening. Furthermore, the eccentric LV remodeling in FH- athletes was associated with a more robust enhancement of LV diastolic function than the concentric LV remodeling that occurred in FH+ athletes. In conclusion, these findings suggest that patterns of exercise-induced LV remodeling are strongly associated with FH history status. (c) 2009 Elsevier Inc. (Am J Cardiol 2009;104:101-106)

AB We sought to assess the risk of sudden cardiac death (SCD) and ventricular arrhythmia after alcohol septal ablation (ASA) for obstructive hypertrophic cardiomyopathy. ASA is a nonsurgical alternative to septal myectomy for treatment of symptomatic, drug-refractory, obstructive hypertrophic cardiomyopathy. The effect of ASA on ventricular arrhythmia risk is not well established. We examined the rates of SCD among 89 patients treated with ASA. The secondary end point was ventricular tachycardia/ventricular fibrillation (VT/VF), appropriate implantable cardioverter defibrillator (ICD) therapy, or cardiac arrest after ASA among those with implanted ICDs or permanent pacemakers (n = 42). Patients were classified as either high-risk or low-risk on the basis of established clinical indications for ICD implantation. No mortality was attributable to SCD at a mean follow-up of 5.0 +/- 2.3 years in the entire cohort. Among the 42 patients with an ICD or permanent pacemaker, 9 had documented VT/VF, cardiac arrest, or appropriate ICD therapy, resulting in an annual event rate of 4.9%/year. The annual event rate for VT/VF, cardiac arrest, or appropriate ICD therapy was 2.8%/year (4 of 29 patients) in low-risk patients and 13.4% in high-risk patients (5 of 13 patients). A 10-mm Hg increase in the immediate post-ASA gradient was associated with a hazard ratio of 2.66 for arrhythmic events (95% confidence interval 1.55 to 4.56, p <0.001). In conclusion, ASA was performed in patients with highly symptomatic, drug-refractory hypertrophic cardiomyopathy with no mortality attributable to SCD and an annual rate of VT/VF, cardiac arrest, or appropriate ICD therapy of 4.9%/year.

AB The ability to interpret epidemiologic observations is limited because of potential residual confounding by correlated dietary components. Dietary pattern analyses by factor analysis or partial least squares may overcome the limitation. To examine confounding by dietary pattern as well as standard risk factors and selected nutrients, the authors modeled the longitudinal association between alcohol consumption and 7-year risk of type 2 diabetes mellitus in 2,879 healthy adults enrolled in the Framingham Offspring Study (1991-2001) by Cox proportional hazard models. After adjustment for standard risk factors, consumers of >= 9.0 drinks/week had a significantly lower risk of type 2 diabetes mellitus compared with abstainers (hazard ratio = 0.47, 95% confidence interval (CI): 0.27, 0.81). Adjustment for selected nutrients had little effect on the hazard ratio, whereas adjustment for dietary pattern variables by factor analysis significantly shifted the hazard ratio away from null (hazard ratio = 0.33, 95% CI: 0.17, 0.64) by 40.0% (95% CI: 16.8, 57.0; P = 0.002). Dietary pattern variables by partial least squares showed similar results. Therefore, the observed inverse association, consistent with past studies, was confounded by dietary patterns, and this confounding was not captured by individual nutrient adjustment. The data suggest that alcohol intake, not dietary patterns associated with alcohol intake, is responsible for the observed inverse association with type 2 diabetes mellitus risk.

TI Relation of Baseline Serum Potassium Levels to Angiographic Findings in
Patients With Known or Suspected Coronary Artery Disease
SO AMERICAN JOURNAL OF HYPERTENSION
LA English
DT Article
ID SPONTANEOUSLY HYPERTENSIVE RATS; ACUTE MYOCARDIAL-INFARCTION; BLOOD-CELL
COUNT; CARDIAC MORTALITY; PREDICTOR
AB BACKGROUND
In experimental animal studies, potassium has been demonstrated to protect against the development of atherosclerosis through a variety of mechanisms. Data regarding the role of potassium in the development of human atherosclerosis are sparse. The objective of this study was to determine the association between plasma potassium levels and angiographically defined coronary artery disease (CAD).
METHODS
In a cohort of 389 male patients undergoing coronary angiography for a variety of clinical indications, the association between baseline serum potassium levels and the extent of angiographically defined atherosclerosis was analyzed. Adjustments were made for clinical and laboratory variables (including inflammatory markers) known to be associated with atherosclerosis.
RESULTS
By multivariate logistic regression analysis, baseline serum potassium levels were an independent predictor of the presence of multivessel disease (odds ratio (OR) 1.31, 95% confidence interval (CI) 1.01-1.69; P<0.05). In addition, in the non-myocardial infarction subpopulation of patients, serum potassium was also an independent predictor of the presence of multivessel disease by multivariate logistic regression analysis (OR 1.34, 95% Cl, 1.02-1.76; P<0.05). In the myocardial infarction (MI) subpopulation, serum potassium was not a predictor of multivessel disease, possibly due to the confounding effect of hypokalemia known-to be present during MI.
CONCLUSIONS
These data demonstrate that a simple baseline serum potassium level is independently associated with the presence of multivessel disease, even in the context of clinical CAD risk factors and other established inflammatory markers.

TI Plasma Renin Test-Guided Drug Treatment Algorithm for Correcting
Patients With Treated but Uncontrolled Hypertension: A Randomized
Controlled Trial

RENAL-FUNCTION; THERAPY; PATHOPHYSIOLOGY; DIAGNOSIS
AB BACKGROUND
Undefined pathophysiologic mechanisms likely contribute to unsuccessful anti hypertensive drug therapy. The renin test-guided therapeutic (RTGT) algorithm is based on the concept that, irrespective of current drug treatments, subnormal plasma renin activity (PRA) (<0.65 ng/ml/h) indicates sodium-volume excess "V" hypertension, whereas values >= 0.65 indicate renin-angiotensin vasoconstriction excess "R" hypertension.
METHODS
The RTGT algorithm was applied to treated, uncontrolled hypertensives and compared to clinical hypertension specialists' care (CHSC) without access to PRA. RTGT protocol: "V" patients received natriuretic anti-"V"drugs (diuretics, spironolactone, calcium antagonists, or alpha(1)-blockers) while withdrawing antirenin "R" drugs (converting enzyme inhibitors, angiotensin receptor antagonists, or beta-blockers). Converse strategies were applied to "R" patients. Eighty-four ambulatory hypertensives were randomized and 77 qualified for the intention-to-treat analysis including 38 in RTGT (63.9 +/- 1.8 years; baseline blood pressure (BP) 157.0 +/- 2.6/87.1 +/- 2.0 mm Hg; PRA 5.8 +/- 1.6; 3.1 +/- 0.3 antihypertensive drugs) and 39 in CHSC (58.0 +/- 2.0 years; BD 153.6 +/- 2.3/91.9 +/- 2.0; PRA 4.6 +/- 1.1; 2.7 +/- 0.2 drugs).
RESULTS
BP was controlled in 28/38 (74% (RTGT)) vs. 23/39 (59% (CHSC)), P=0.17, falling to 127.9 +/- 2.3/73.1 +/- 1.8 vs. 134.0 +/- 2.8/79.8 +/- 1.9 mm Hg, respectively. Systolic BP (SBP) fell more with RTGT (-29.1 +/- 3.2 vs. -19.2 +/- 3.2 mm Hg, P=0.03), whereas diastolic BP (DBP) declined similarly (P=0.32). Although final anti hypertensive drug numbers were similar (3.1 +/- 0.2 (RTGT) vs. 3.0 +/- 0.3 (CHSC), P=0.73) in "V" patients, 60% (RTGT) vs. 11% (CHSC) of "R" drugs were withdrawn and BP medications were reduced (-0.5 +/- 03 vs. +0.7 +/- 0.3, P=0.01).
CONCLUSIONS
In treated but uncontrolled hypertension, RTGT improves control and lowers BP equally well or better than CHSC, indicating that RTGT provides a reasonable strategy for correcting treated but uncontrolled hypertension.

AB Background: Anemia augments the already high rates of fatal and major nonfatal cardiovascular and renal events in individuals with type 2 diabetes. In 2004, we initiated the Trial to Reduce Cardiovascular Events With Aranesp Therapy (TREAT). This report presents the baseline characteristics and therapies of TREAT participants and subgroups defined by the presence or absence of overt proteinuria and history of cardiovascular disease. The design of TREAT and baseline characteristics also are compared with 2 recent trials of nondialysis patients with chronic kidney disease (CKD) in which treatment with another erythropoiesis-stimulating agent targeting greater hemoglobin levels had either a neutral or adverse effect on clinical outcomes.
Study Design: Randomized trial.
Setting & Participants: 4,044 participants with type 2 diabetes, CKD (defined as estimated glomerular filtration rate of 20 to 60 mL/min/1.73 m(2)), and anemia (hemoglobin <= 11 g/dL) from 24 countries.
Intervention: Darbepoetin alfa to attempt to increase hemoglobin levels to 13 g/dL compared with placebo.
Outcomes: TREAT is an event-driven design to continue until approximately 1,203 patients experience a primary event: the composite end point of death or cardiovascular morbidity (nonfatal myocardial infarction, congestive heart failure, stroke, or hospitalization for myocardial ischemia). The composite end point of death or need for long-term renal replacement therapy also is a primary end point.
Conclusions: With several-fold more patient-years and a placebo arm, TREAT will provide a robust estimate of the safety and efficacy of darbepoetin alfa and generate prospective data regarding the risks of major cardiovascular and renal events in a contemporarily managed cohort of patients with type 2 diabetes, CKD, and anemia.

AB Silicate calculi are common in some mammals, such as dogs and sheep, but extremely rare in humans. We report a case of silicate calculi in a woman using oral over-the-counter Uncaria tomentosa, Digestive Advantage and FlexProtex supplements. All 3 contained the excipient silica dioxide. Stone analysis showed composition of 100% silicate. The nephrolithiasis promptly abated after discontinuation of the products containing silica, then returned when the patient restarted her supplements. This case emphasizes the importance of stone analysis when obvious causes of nephrolithiasis are unclear and highlights the concerns of using over-the-counter supplements without substantial oversight.

AB Huntington disease (HD) is a dominantly transmitted neurodegenerative disorder that arises from expansion of a CAG trinucleotide repeat on chromosome4p16.3. CAG repeat allele lengths are defined as fully penetrant at >= 40, reduced penetrance at 36-39, high normal at 27-35, and normal at <= 26. Fathers, but not mothers, with high normal alleles are at risk of transmitting potentially penetrant HD alleles (>= 36) to offspring. We estimated the conditional probability of an offspring inheriting an expanded penetrant allele given a father with a high normal allele by applying probability definitions and rules to estimates of HD incidence, paternal birth rate, frequency of de novo HD, and frequency of high normal alleles in the general population. The estimated probability that a male high normal allele carrier will have an offspring with an expanded penetrant allele ranges from 1/6,241 to 1/951. These estimates may be useful in genetic counseling for male high normal allele carriers. (C) 2009 Wiley-Liss, Inc.

AB BACKGROUND: Frailty is common in the elderly and in persons with chronic diseases. Few studies have examined the association of frailty with chronic kidney disease.
METHODS: We used data from the Third National Health and Nutrition Examination Survey to estimate the prevalence of frailty among persons with chronic kidney disease. We created a definition of frailty based on established validated criteria, modified to accommodate available data. We used logistic regression to determine whether and to what degree stages of chronic kidney disease were associated with frailty. We also examined factors that might mediate the association between frailty and chronic kidney disease.
RESULTS: The overall prevalence of frailty was 2.8%. However, among persons with moderate to severe chronic kidney disease (estimated glomerular filtration rate < 45 mL/min/1.73 m(2)), 20.9% were frail. The odds of frailty were significantly increased among all stages of chronic kidney disease, even after adjustment for the residual effects of age, sex, race, and prevalent chronic diseases. The odds of frailty associated with chronic kidney disease were only marginally attenuated with additional adjustment for sarcopenia, anemia, acidosis, inflammation, vitamin D deficiency, hypertension, and cardiovascular disease. Frailty and chronic kidney disease were independently associated with mortality.
CONCLUSION: Frailty is significantly associated with all stages of chronic kidney disease and particularly with moderate to severe chronic kidney disease. Potential mechanisms underlying the chronic kidney disease and frailty connection remain elusive. (C) 2009 Elsevier Inc. All rights reserved. The American Journal of Medicine (2009) 122, 664-671

AB BACKGROUND: End-stage renal disease disproportionately affects black persons, but it is unknown when in the course of chronic kidney disease racial differences arise. Understanding the natural history of racial differences in kidney disease may help guide efforts to reduce disparities.
METHODS: We compared white/black differences in the risk of end-stage renal disease and death by level of estimated glomerular filtration rate (eGFR) at baseline in a national sample of 2,015,891 veterans between 2001 and 2005.
RESULTS: Rates of end-stage renal disease among black patients exceeded those among white patients at all levels of baseline eGFR. The adjusted hazard ratios for end-stage renal disease associated with black versus white race for patients with an eGFR >= 90, 60-89, 45-59, 30-44, 15-29, and <15 mL/min/1.73m(2), respectively, were 2.14 (95% confidence interval [CI], 1.72-2.65), 2.30 (95% CI, 2.02-2.61), 3.08 (95% CI, 2.74-3.46), 2.47 (95% CI, 2.26-2.70), 1.86 (95% CI, 1.75-1.98), and 1.23 (95% CI, 1.12-1.34). We observed a similar pattern for mortality, with equal or higher rates of death among black persons at all levels of eGFR. The highest risk of mortality associated with black race also was observed among those with an eGFR 45-59 mL/min/1.73m(2) (hazard ratio 1.32, 95% CI, 1.27-1.36).
CONCLUSION: Racial differences in the risk of end-stage renal disease appear early in the course of kidney disease and are not explained by a survival advantage among blacks. Efforts to identify and slow progression of chronic kidney disease at earlier stages may be needed to reduce racial disparities. Published by Elsevier Inc.

AB The recent birth of octuplets unleashed a firestorm of publicity, casting a harsh light on the mother and her presumed inadequacies as a parent. It also raised questions about the role of reproductive endocrinologists. Herein we consider 3 aspects of this question: should reproductive endocrinologists consider the economic interests of society, should they consider parenting abilities, and should the number of embryos transferred be limited? We conclude that the ethical obligation of reproductive endocrinologists does not extend to protection of society's economic interests; that reproductive endocrinologists, although poorly trained and situated to gauge an individual's ability to parent, can in extreme circumstances refuse to provide assisted reproductive technology; and that a firm limit on the number of transferred embryos is ethically and medically appropriate.

AB Introduction: Accurate prediction of the timing of the pubertal growth spurt and the amount of remaining growth are factors that affect treatment decisions in orthodontics, orthognathic surgery, and dental implantology. For many years, medical and dental professionals have considered hand-wrist radiographs the method of choice for the assessment of skeletal maturity. Insulin-like growth factor 1 (IGF-1) mirrors growth hormone levels and is used by endocrinologists to diagnose growth hormone disturbances. Methods: The objective of this study was to establish a relationship between IGF-1 levels collected from blood-spot samples and hand-wrist radiographs at various skeletal stages. Eighty-four subjects (45 female, 39 male) between the ages of 5 and 25 were included in the study. Each subject had personal information, a hand-wrist radiograph, and a blood-spot sample collected on the same day. Results: The IGF-1 levels were highest at the hand-wrist skeletal stages that were previously associated with the greatest amount of mandibular growth. These levels were significantly higher than at prepuburtal and postpubertal stages. In the postpubertal group, the IGF-1 levels were lower as the subjects' ages increased and they moved away from the onset of puberty. Conclusions: Longitudinal data are necessary to confirm the usefulness of this technique in predicting the timing, the intensity, and the end of the growth spurt.

AB Therapeutic revascularization with either exogenous angiogenic growth factors or vascular cells has yet to demonstrate efficacy in the clinic. Injection of angiogenic growth factors often produces unstable and abnormal blood vessels. Blood vascular networks derived from implanted endothelial cells persist only transiently due to the insufficient recruitment of perivascular cells. We hypothesize that a combination of the two approaches may act synergistically to yield a better result. To enhance the recruitment of perivascular cells, human umbilical vein endothelial cells were genetically modified to overexpress platelet-derived growth factor (PDGF)-BB. PDGF-BB overexpression promoted both proliferation and migration of perivascular precursor cells (10T1/2 cells) in vitro. When mock-infected endothelial cells were implanted alone in vivo, they formed transient blood vascular networks that regressed by day 30. PDGF-BB overexpression enhanced the survival of endothelial cells in vivo. However, the PDGF-BB-expressing vessel network failed to establish patent blood flow. Co-implantation of PDGF-BB-overexpressing endothelial cells with 10T1/2 cells paradoxically resulted in the rapid regression of the vascular networks in vivo. PDGF-BB stimulated the expression of both chemokine (C-C motif) ligand 2 (CCL2) and CCL7 in 10T1/2 cells and led to the increased accumulation of macrophages in vivo. These results suggest a potential negative interaction between angiogenic growth factors and vascular cells; their use in combination should be carefully tested in vivo for such opposing effects.

AB Objective: Many individuals with spina bifida have impairments that limit mobility and functional independence. Sedentary lifestyles and social isolation are very prevalent. This study evaluated the association between the use of mobility devices and degree of socialization.
Design: A retrospective chart review was performed on 208 adults with spina bifida attending a university-based clinic. Data collected included the Craig Handicap Assessment Reporting Technique-Short Form, Beck Depression Inventory, and data on wheelchair and other assistive technology use. We hypothesized that community and home mobility and social Integration, as measured by the Craig Handicap Assessment Reporting Technique-Short Form, would be lower for manual and power wheelchair users than for ambulators, regardless of depression scores or shunt history.
Results: We found that individuals with spina bifida who used both manual and power wheelchairs do have lower daily home and community activity levels compared with ambulators, but that most individuals with spina bifida have low social integration and economic self-sufficiency scores, regardless of whether they can ambulate or use wheelchairs. These findings were not explained by wheelchair quality because most were prescribed high-quality devices. A high prevalence of depression was also found.
Conclusions: Special considerations for wheelchair provision are discussed. Additional research is needed to identify other barriers to social integration.

Cortagine, a CRF1 agonist, induces stresslike alterations of colonic function and visceral hypersensitivity in rodents primarily through peripheral pathways. Am J Physiol Gastrointest Liver Physiol 297: G215-G227, 2009. First published April 30, 2009; doi:10.1152/ajpgi.00072.2009.-Corticotropin-releasing factor (CRF) 1 receptor (CRF1) activation in the brain is a core pathway orchestrating the stress response. Anatomical data also support the existence of CRF signaling components within the colon. We investigated the colonic response to intraperitoneal (ip) injection of cortagine, a newly developed selective CRF1 peptide agonist. Colonic motor function and visceral motor response (VMR) were monitored by using a modified miniaturized pressure transducer catheter in adult conscious male Sprague-Dawley rats and C57Bl/6 mice. Colonic permeability was monitored by the Evans blue method and myenteric neurons activation by Fos immunohistochemistry. Compared with vehicle, cortagine (10 mu g/kg ip) significantly decreased the distal colonic transit time by 45% without affecting gastric transit, increased distal and transverse colonic contractility by 35.6 and 66.2%, respectively, and induced a 7.1-fold increase in defecation and watery diarrhea in 50% of rats during the first hour postinjection whereas intracerebroventricular (icv) cortagine (3 mu g/rat) had lesser effects. Intraperitoneal (ip) cortagine also increased colonic permeability, activated proximal and distal colonic myenteric neurons, and induced visceral hypersensitivity to a second set of phasic colorectal distention (CRD). The CRF antagonist astressin (10 mu g/kg ip) abolished ip cortagine-induced hyperalgesia whereas injected icv it had no effect. In mice, cortagine (30 mu g/kg ip) stimulated defecation by 7.8-fold, induced 60% incidence of diarrhea, and increased VMR to CRD. Stresslike colonic alterations induced by ip cortagine in rats and mice through restricted activation of peripheral CRF1 receptors support a role for peripheral CRF1 signaling as the local arm of the colonic response to stress.

Role of lysophosphatidylcholine in brush-border intestinal alkaline phosphatase release and restoration. Am J Physiol Gastrointest Liver Physiol 297: G207-G214, 2009. First published April 30, 2009; doi:10.1152/ajpgi.90590.2008.-Intestinal alkaline phosphatase (IAP) is a brush-border membrane ectoenzyme (BBM-IAP) that is released into the lumen (L-IAP) after a high-fat diet. We examined the effects of oil feeding and the addition of mixed-lipid micelles on the formation of L-IAP in oil-fed rat intestine, Caco-2 cell monolayers, and mouse intestinal loops. We localized IAP in the duodenum of rats fed corn oil using fluorescence microscopy with enzyme-labeled fluorescence-97 as substrate. Four hours after oil feeding, L-IAP increased similar to 10-fold accompanied by the loss of BBM-IAP, consistent with BBM-IAP release. Rat IAP isozyme mRNAs progressively increased 4-6 h after oil feeding, followed by the increase of IAP activity in the subapical location at 6 h, consistent with the restoration of IAP protein. Postprandial lipid-micelle components, sodium taurocholate with or without oleic acid, mono-oleylglycerol, cholesterol, or lysophosphatidylcholine (lysoPC) were applied singly or as mixed-lipid micelles to the apical surface of polarized Caco-2 cell monolayers. LysoPC increased L-IAP > 10-fold over basal release. LysoPC released IAP into the apical medium more than other intestinal brush-border enzymes, 5'-nucleotidase, sucrase, aminopeptidase N, and lactase, without comparable lactate dehydrogenase release or cell injury. LysoPC increased human IAP mRNA levels by 1.5-fold in Caco-2 cells. Luminally applied lysoPC also increased release of IAP preferentially in mouse intestinal loops. These data show that lysoPC accelerates the formation of L-IAP from BBM-IAP, followed by enhanced IAP synthesis, suggesting the role that lysoPC might play in the turnover of brush-border proteins.

Am J Physiol Heart Circ Physiol 297: H400-H408, 2009. First published May 22, 2009; doi: 10.1152/ajpheart.01254.2008.-Increased plasma levels of lactosylceramide (LacCer) have been associated with cardiovascular disease. However, it is largely unknown whether LacCer directly contributes to dysfunction of smooth muscle cells (SMCs), a key event in vascular lesion formation. In the present study, we determined the effects and potential mechanisms of LacCer on cell migration and proliferation in human aortic SMCs (AoSMCs). Cell migration and proliferation were determined by a modified Boyden chamber assay and nonradioactive colorimetric (MTS) assay, respectively. We found that LacCer significantly induced AoSMC migration and proliferation in a concentration- and time-dependent manner. In addition, LacCer significantly upregulated the expression of PDGFR-B, integrins (alpha(v) and beta(3)), and matrix metalloproteinases (matrix metalloproteinase-1 and -2) at both mRNA and protein levels, as determined by real-time PCR and Western blot analyses, respectively. Furthermore, LacCer increased superoxide anion production and the transient phosphorylation of ERK1/2 in AoSMCs, as determined by dihydroethidium staining and immunoassay, respectively. Accordingly, LacCer-induced cell migration and proliferation were effectively blocked by antioxidants (seleno-L-methionine and Mn tetrakis porphyrin) and by a specific ERK1/2 inhibitor. Thus, LacCer promotes cell migration and proliferation through oxidative stress and activation of ERK1/2 in AoSMCs. These findings demonstrate the functional role of LacCer in the vascular disease pathogenesis.

First published April 17, 2009; doi: 10.1152/ajplung. 90381.2008.-IL-6 overexpression protects mice from hyperoxic acute lung injury in vivo, and treatment with IL-6 protects cells from oxidant-mediated death in vitro. The mechanisms of protection, however, are not clear. We characterized the expression, localization, and regulation of Bax, a proapoptotic member of the Bcl-2 family, in wild-type (WT) and IL-6 lung-specific transgenic (Tg(+)) mice exposed to 100% O(2) and in human umbilical vein endothelial cells (HUVEC) treated with H(2)O(2) and IL-6. In control HUVEC treated with H(2)O(2) or in WT mice exposed to 100% O(2), a marked induction of Bax translocation and dimerization was associated with increased JNK and p38 kinase activity. In contrast, specific JNK or p38 kinase inhibitors or treatment with IL-6 inhibited Bax mitochondrial translocation and apoptosis of HUVEC. IL-6 Tg(+) mice exposed to 100% O(2) exhibited enhanced phosphatidylinositol 3-kinase (PI3K)/Akt kinase and increased serine phosphorylation of Bax at Ser184 compared with WT mice. The PI3K-specific inhibitor LY-2940002 blocked this IL-6-induced Bax phosphorylation and promoted cell death. Furthermore, IL-6 potently blocked hyperoxia-or oxidant-induced Bax insertion into mitochondrial membranes. Thus IL-6 functions in a cytoprotective manner, in part, by suppressing Bax translocation and dimerization through PI3K/Akt-mediated Bax phosphorylation.

First published May 13, 2009; doi:10.1152/ajpregu.90502.2008.-Neoangiogenesis is a critical phenomenon enabling the growth and metastasis of tumors, and inhibitors of neoangiogenesis have been recently added to the armamentarium of anticancer therapies available for clinical use. Dysregulated signaling through the vascular endothelial growth factor ( VEGF) pathway has been implicated as a key mediator of neoangiogenesis in tumors. Agents that block signaling through the VEGF pathway demonstrated tumor shrinkage in preclinical models and were therefore developed as anticancer therapies for use in humans. VEGF kinase inhibitors are being used in the treatment of a wide variety of cancers, and recent studies have shown that patients will likely require long-term treatment with these agents. Hypertension has emerged as a frequent side effect associated with agents that block signaling through the VEGF pathway. A thorough understanding of the mechanisms underlying hypertension is crucial to developing appropriate therapeutic strategies for treating hypertension associated with VEGF kinase inhibitors. Several recent studies have advanced our understanding of the pathophysiology of hypertension associated with VEGF kinase inhibitors and will be the subject of this review.

AB Background: Almost 1 million Americans are infected with HIV, yet it is estimated that as many as 250,000 of them do not know their serostatus. This study examined whether people residing in states with statutes requiring written informed consent prior to HIV testing were less likely to report a recent HIV test.
Methods: The study is based on survey data from the 2004 Behavioral Risk Factor Surveillance System. Logistic regression was used to assess the association between residence in a state with a pre-test written informed-consent requirement and individual self-report of recent HIV testing. The regression analyses controlled for potential state- and individual-level confounders.
Results: Almost 17% of respondents reported that they had been tested for HIV in the prior 12 months. Ten states had statutes requiring written informed consent prior to routine HIV testing; nine of those were analyzed in this study. After adjusting for other state- and individual-level factors, people who resided in these nine states were less likely to report a recent history of HIV testing (OR=0.85; 95% CI=0.80, 0.90). The average marginal effect was -0.02 (p<0.001, 95% CI=-0.03, -0.01); thus, written informed-consent statutes are associated with a 12% reduction in HIV testing from the baseline testing level of 17%. The association between a consent requirement and lack of testing was greatest among respondents who denied HIV risk factors, were non-Hispanic whites, or who had higher levels of education.
Conclusions: This study's findings suggest that the removal of written informed-consent requirements might promote the non-risk-based routine-testing approach that the Centers for Disease Control and Prevention (CDC) advocates in its new testing guidelines.

TI Diagnosis and Treatment of PTSD-Related Compulsive Checking Behaviors in
Veterans of the Iraq War: The Influence of Military Context on the
Expression of PTSD Symptoms
SO AMERICAN JOURNAL OF PSYCHIATRY
LA English
DT Editorial Material
ID EXPOSURE; DISORDER
AB This case study presents an overview of the conceptualization and treatment of two veterans of the Iraq War who presented for combat-related treatment at a Veterans Administration Medical Center. In addition to posttraumatic stress disorder (PTSD) symptoms of reexperiencing, arousal, and avoidance, the veterans exhibited compulsive checking behaviors that appear to be influenced by theater-specific combat duties and traumatic events. These cases represent what the authors believe to be an increasingly common expression of PTSD in veterans of the Iraq and Afghanistan wars. Both veterans were treated with prolonged exposure therapy, which includes imaginal and in vivo exposure to anxiety-provoking stimuli, processing of traumatic events, and self-assessment of anxiety. Treatment also included in vivo exposure with response prevention techniques borrowed from the literature on obsessive-compulsive disorder to address compulsive checking behaviors within the ecological context of each patient's symptom presentation. Measures related to PTSD and depression were obtained before, during, and after treatment. Treatment was associated with significant declines in symptom severity and improved functioning for both veterans. The unique nature of the conflict in the Middle East represents role challenges for soldiers that affect symptom presentation. Variations in symptom presentation can in turn complicate efforts to identify and appropriately address PTSD-related health concerns in this population. Thus, clinicians and researchers must remain cognizant of how theater-specific duties influence the manifestation and treatment of PTSD in order to provide optimal care to a new generation of veterans.

ID LESSER TROCHANTER; TEAR
AB OBJECTIVE. The purpose of this study was to describe the MRI findings of an entity in which patients present with hip pain, abnormal MR signal intensity of the quadratus femoris muscle, and narrowing of the ischiofemoral space.
MATERIALS AND METHODS. We reviewed MR images of 12 hips in nine patients with hip pain and abnormal MR signal intensity of the quadratus femoris muscle. Using axial MR images, two musculoskeletal radiologists measured the ischiofemoral and quadratus femoris spaces. We also examined changes to muscles and tendons for the presence of edema and tears. Data were compared with 11 hips in 10 control subjects. Statistical analyses determined interobserver variability and differences between groups.
RESULTS. Subjects with an abnormal quadratus femoris muscle were all women 30-71 years old ( mean age, 53 years) and had significantly narrower ischiofemoral spaces when compared with control subjects (13 +/- 5 vs 23 +/- 8 mm, respectively; p = 0.002). The quadratus femoris space was significantly narrower in affected subjects (7 +/- 3 vs 12 +/- 4 mm; p = 0.002). Abnormalities of the quadratus femoris muscle included edema (100%), partial tear (33%), and fatty infiltration (8%). The hamstring tendons of affected subjects showed evidence of edema (50%) and partial tears (25%).
CONCLUSION. Ischiofemoral impingement may represent a cause of hip pain and should be considered in cases with MR signal abnormality of quadratus femoris muscle.

TI Treatment of Recalcitrant Iliotibial Band Friction Syndrome With Open
Iliotibial Band Bursectomy Indications, Technique, and Clinical Outcomes
SO AMERICAN JOURNAL OF SPORTS MEDICINE
LA English
DT Article
DE iliotibial band friction syndrome; iliotibial band bursectomy;
arthroscopy; lateral knee pain
ID MR-IMAGING FINDINGS; SURGICAL-TREATMENT; RUNNERS; KNEE; MANAGEMENT
AB Background: Iliotibial band friction syndrome (ITBFS) is an overuse injury causing lateral knee pain. There is evidence that the pathological lesion is in fact an inflamed bursa underlying the iliotibial band (ITB) rather than an inflamed ITB itself.
Hypothesis: Resection of the bursa underlying the ITB in ITBFS patients will relieve their pain and allow them to return to their preinjury activity level.
Study Design: Case series; Level of evidence, 4. Methods: We describe the technique of ITB bursectomy and report a minimal 20-month follow-up of patients who had ITB bursectomies performed by a single surgeon. The patients completed a survey detailing their preoperative and postoperative symptoms and activities.
Results: The senior author performed 12 consecutive cases of ITB bursectomies (12 patients). One was excluded from the study (previous microfracture). The average age at surgery was 32 years (standard deviation, 5; range, 24-41). There were 7 men and 4 women. Postoperatively, patients were able to return to their preinjury Tegner activity levels, and the visual analog pain scores decreased by an average of 6 points (P < .001). Six patients were completely satisfied with the surgical outcome, 3 were mostly satisfied, 2 were somewhat satisfied, and none were dissatisfied. Nine of 11 patients said that knowing what they know now, they would have the surgery performed again for the same problem.
Conclusion: Iliotibial band bursectomy successfully reduces knee pain in patients with ITBFS and allows them to return to their preinjury level of activity. The great majority of patients were satisfied with the results of the procedure.

AB BACKGROUND: A dedicated colorectal cancer (CRC) center was created in a Veterans Affairs Medical Center with the intent of improving quality of patient care and multidisciplinary cooperation.
METHODS: Retrospective and prospective databases before and after creation of the CRC center, respectively, were created. Patients entered in each database included those requiring surgical intervention for CRC treatment. Statistical analyses included Fisher's exact, chi-square, and unpaired Student t tests as well as analysis of variance.
RESULTS: The overall quality of care of CRC patients has improved as evidenced by a larger percentage of complete, margin-negative resections (P <.05) as well as an increase in the number of lymph nodes excised at surgery (P <.0001). Furthermore, a multidisciplinary approach is clearly beneficial as evidenced by the increased number of CRC patients receiving appropriate multidisciplinary therapy (P <.0001).
CONCLUSIONS: A dedicated CRC center has significantly improved quality of care for CRC patients. (C) 2009 Published by Elsevier Inc.

RESPONSES; BINDING; INTESTINE
AB BACKGROUND: Parenteral nutrition (PN) increases post-trauma pneumonia versus enteral feeding. PN impairs murine immunoglobulin A (IgA) airway defenses and abrogates a normal IgA increase following injury. This work investigates the effect of type/route of nutrition on lung IgA and its transport protein, polymeric immunoglobulin receptor (pIgR), after injury.
METHODS: Catheterized mice were randomized to Chow or PN for 5 days and sacrificed without injury (Chow: n = 12; PN n = 11), or 8 hours after laparotomy + neck incisions (Chow-injury: n = 11, PN-injury: n = 13). Bronchoalveolar lavage (BAL) and lung IgA levels were analyzed by enzyme-linked immunosorbent assay (ELISA) and lung pIgR by Western blot.
RESULTS: BAL IgA levels increased in Chow-injury versus PN-injury (P <.01) with no differences in pIgR. PN-injury tissue IgA levels decreased versus Chow (P <.01), Chow-injury (P <.01), and PN (P <.05).
CONCLUSIONS: PN impairs the airway IgA response to injury but not due to impaired IgA transport capacity/pIgR level. (C) 2009 Elsevier Inc. All rights reserved.

TI Basal Cytokeratin and Epidermal Growth Factor Receptor Expression Are
Not Predictive of BRCA1 Mutation Status in Women With Triple-negative
Breast Cancers

LA English
DT Article
DE breast cancer; basal; BRCA1 mutation; basal cytokeratins
ID IMMUNOHISTOCHEMICAL MARKERS; EPITHELIAL PHENOTYPE; ESTROGEN-RECEPTOR;
TUMORS; CARCINOMA
AB Background: Over 80% of breast cancers in women with germline BRCA1 mutations are estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2-negative ("triple negative") and most of these have a basal-like phenotype by expression profiling and immunophenotypic analysis. However, whether or not expression of biomarkers characteristic of basal-like breast cancers helps to define a subset of women with triple-negative breast cancers who are likely to harbor BRCA1 mutations is an Unresolved issue.
Methods: We randomly identified 165 women from the Dana-Farber/Harvard Cancer Center SPORE annotated specimen bank with primary invasive, triple-negative breast cancers. Tissue microarrays were constructed by obtaining triplicate 0.6 mm cores from available paraffin blocks from 130 cases: only unstained slides were available for immunostaining from 35 cases. Slides cut from the tissue microarrays and the unstained slides were immunostained for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (to confirm triple-negative status) and for several markers that have been reported to be useful in defining the basal-like phenotype, including basal cytokeratins CK5/6, CK14, and CK17 and epidermal growth factor receptor (EGFR). Full sequencing analysis for BRCA1 germline mutations was performed on blood specimens from all cases. The final Study population consisted of 144 cases in which (1) triple-negative status was confirmed; (2) there was sufficient material for analysis of basal cytokeratins and EGFR; and (3) germline BRCA1 mutation status was known.
Results: Among these triple-negative breast cancer cases, 97 (67%) expressed one or more basal cytokeratins and 102 (71%) showed EGFR expression. Basal cytokeratin expression was detected in 65% of the tumor from the 20 BRCA1 mutation carriers and in 68% of the cancers from women without mutations (P = NS). EGFR expression was identified in a similar proportion of tumors from women with and without BRCA1 Mutations (75% vs. 72%, P = NS).
Conclusions: Basal cytokeratin and EGFR expression are both highly prevalent among triple-negative breast cancers. The frequency of expression of basal cytokeratins and EGFR was similar in women with and without BRCA1 mutations. Therefore, although the expression of basal cytokeratins and/or EGFR can be used to identify triple-negative breast cancers that have a basal-like phenotype, expression of these markers alone is not sufficient to distinguish which women with triple-negative breast cancers are likely to harbor BRCA1 germline mutations.

LOCAL-ANESTHETICS; SENSORY NEURONS; PAIN; RAT; HYPERALGESIA; NERVE; SITE
AB Background: Nociceptive-selective local anesthesia is produced by entry of the permanently charged lidocaine-derivative QX-314 into nociceptors when coadministered with capsaicin, a transient receptor potential vanilloid 1 (TRPV1) channel agonist. However, the pain evoked by capsaicin before establishment of the QX-314-mediated block would limit clinical utility. Because TRPV1 channels are also activated by lidocaine, the authors tested whether lidocaine can substitute for capsaicin to introduce QX-314 into nociceptors through TRPV1 channels and produce selective analgesia.
Methods: Lidocaine (0.5% [17.5 mM], 1% [35 mM], and 2% [70 mM]) alone, QX-314 (0.2% [5-8 mM]) alone, and a combination of the two were injected subcutaneously and adjacent to the sciatic nerve in rats and mice. Mechanical and thermal responsiveness were measured, as was motor block.
Results: Coapplication of 0.2% QX-314 with lidocaine prolonged the nociceptive block relative to lidocaine alone, an effect attenuated in TRPV1 knockout mice. The 0.2% QX-314 alone had no effect when injected intraplantary or perineurally, and it produced only weak short-lasting inhibition of the cutaneous trunci muscle reflex. Perisciatic nerve injection of lidocaine with QX-314 produced a differential nociceptive block much longer than the transient motor block, lasting 2 h (for 1% lidocaine) to 9 h (2% lidocaine). Triple application of lidocaine, QX-314, and capsaicin further increased the duration of the differential block.
Conclusions: Coapplication of lidocaine and its quaternary derivative QX-314 produces a long-lasting, predominantly nociceptor-selective block, likely by facilitating QX-314 entry through TRPV1 channels. Delivery of QX-314 into nociceptors by using lidocaine instead of capsaicin produces sustained regional analgesia without nocifensive behavior.

TI Am I Doing the Right Thing? Provider Perspectives on Improving
Palliative Care in the Emergency Department
SO ANNALS OF EMERGENCY MEDICINE
LA English
DT Article
ID ILLNESS; TRENDS; LIFE; END
AB Study objective: Although the focus of emergency care is on the diagnosis and treatment of acute illnesses and injuries or the stabilization of patients for ongoing treatment, some patients may benefit from a palliative approach. Little is known about delivering palliative care in the emergency department (ED). We explore the attitudes, experiences, and beliefs of emergency providers about palliative care in the ED, using structured qualitative methods.
Methods: We studied 3 focus groups with 26 providers, including 14 physicians (10 residents, 4 attending physicians), 6 nurses, 2 social workers, and 4 technicians, working in 2 academic EDs in Boston. We used a grounded theory approach to code responses, resolving discrepancies by consensus.
Results: Six distinct themes emerged: (1) participants equated palliative care with end-of-life care; (2) participants disagreed about the feasibility and desirability of providing palliative care in the ED; (3) patients for whom a palliative approach has been established often visit the ED because family members are distressed by end-of-life symptoms; (4) lack of communication between outpatient and ED providers leads to undesirable outcomes leg, resuscitation of patients with a do-not-resuscitate order); (5) conflict around withholding life-prolonging treatment is common leg, between patient's family and written advance directives); and (6) training in pain management is inadequate.
Conclusion: Providers ranked improved communication and documentation from outpatient providers as their highest priority for improvement. Attitudinal and structural barriers may need to be overcome to improve palliative care in the ED. Despite targeted recruitment, attending physician participation was low.

AB OBJECTIVE: To describe the rationale, principles, and dosage calculations for continuous-infusion beta-lactam antibiotics to treat multidrug-resistant bacteria in patients undergoing continuous venovenous hemofiltration (CVVH).
DATA SOURCES: A MEDLINE search (1968-November 2008) of the English-language literature was performed using the terms continuous infusion and Pseudomonas or Acinetobacter, hemofiltration or CVVH or hemodiafiltration or CVVHDF or continuous renal replacement therapy or pharmacokinetics; and terms describing different beta-lactam antibiotics.
STUDY SELECTION AND DATA EXTRACTION: In vitro, in vivo, and human studies were evaluated that used continuous-infusion beta-lactam antibiotics to treat Pseudomonas aeruginosa and Acinetobacter baumannii infections. Studies were reviewed that described the pharmacokinetics of beta-lactam antibiotics during CVVH as well as other modalities of continuous renal replacement therapy.
DATA SYNTHESIS: Continuous infusion of beta-lactam antibiotics, maintaining drug concentrations 4-5 times higher than the minimum inhibitory concentration, is a promising approach for managing infections caused by P. aeruginosa and A. baumannii. Safe yet effective continuous infusion therapy is made difficult by the occurrence of acute renal failure and the need for renal replacement therapy. Case series and pharmacokinetic properties indicate that several beta-lactam antimicrobials that have been studied for continuous infusion, such as cefepime, ceftazidime, piperacillin, ticarcillin, clavulanic acid, and tazobactam, are significantly cleared by hemofiltration. Methodology and formulas are provided that allow practitioners to calculate dosage regimens and reach target drug concentrations for continuous beta-lactam antibiotic infusions during CVVH based on a literature review, pharmacokinetic principles, and our experience at the National Institutes of Health Clinical Center.
CONCLUSIONS: Continuous infusion of beta-lactam antibiotics may be a useful treatment strategy for multidrug-resistant gram-negative infections in the intensive care unit. Well-established pharmacokinetic and pharmacodynamic principles can be used to safely reach and maintain steady-state target concentrations of beta-lactam antibiotics in critical illness complicated by acute renal failure requiring CVVH.

AB Mastopexy after massive weight loss (MWL) poses unique challenges that may not be successfully addressed with traditional mastopexy procedures. Several novel techniques have been proposed to improve esthetic outcomes; however, little data exists to guide the plastic surgeon on choice of technique for individual patients. A literature review revealed 10 articles with specific emphasis on mastopexy techniques in MWL patients. These articles focused on ways to improve shape, projection, and long-term results, using autologous tissue alone or combined with breast implants. Key concepts include increasing volume of the breast by utilizing excess axillary tissue (lateral thoracic/spiral/intercostal artery perforator flap), modification of existing superomedial pedicle techniques to maximize breast volume, and increasing breast parenchymal support with suture fixation and dermal suspension. This article offers an algorithmic approach to treat breast ptosis in the MWL patient based on breast volume, axillary tissue, desired scar location, and preferred surgical technique.

AB Background. Because surgical residents' level of experience may be at its nadir early in the academic year, academic seasonality-or the "July effect"-could affect cardiac surgical outcomes.
Methods. Prospectively collected data from the Department of Veterans Affairs Continuous Improvement in Cardiac Surgery Program were used to identify 70,616 consecutive cardiac surgical procedures performed between October 1997 and October 2007. Morbidity and mortality rates were compared between early (July 1 to August 31, n = 11,975) and late (September 1 to June 30, n = 58,641) periods in the academic year. A prediction model was constructed by using stepwise logistic regression modeling.
Results. The two patient groups had similar demographic and risk variables. Isolated coronary artery bypass grafting accounted for 76.7% of early-period procedures and 75.8% of later-period procedures (p = 0.03). Morbidity rates did not differ significantly between the early (14.0%) and later periods (14.2%; odds ratio [OR], 1.01; 95% confidence interval [CI], 0.96 to 1.07; p = 0.67) and operative mortality was similar, 3.7% vs 3.9% (OR, 0.99; 95% CI, 0.89 to 1.11; p = 0.90). The early portion of the year was associated with longer cardiac ischemia times (84 +/- 40 vs 83 +/- 42 minutes), cardiopulmonary bypass times (126 +/- 52 vs 124 +/- 56 minutes), and total surgical times (295 +/- 90 vs 288 +/- 90 minutes; p < 0.05 for all).
Conclusions. The early part of the academic year was associated with slightly longer operative times; however, risk-adjusted outcomes were similar in both periods. This finding should lessen concerns about the quality of cardiac surgical care at the beginning of the academic year. (Ann Thorac Surg 2009;88:70-5) (C) 2009 by The Society of Thoracic Surgeons

AB Background. Adjustment for case-mix is essential when using observational data to compare surgical techniques or providers. That is most often accomplished through the use of risk models that account for preoperative patient factors that may impact outcomes. The Society of Thoracic Surgeons (STS) uses such risk models to create risk-adjusted performance reports for participants in the STS National Adult Cardiac Surgery Database (NCD). Although risk models were initially developed for coronary artery bypass surgery, similar models have now been developed for use with heart valve surgery, particularly as the proportion of such procedures has increased. The last published STS model for isolated valve surgery was based on data from 1994 to 1997 and did not include patients undergoing mitral valve repair. STS has developed new valve surgery models using contemporary data that include both valve repair as well as replacement. Expanding upon existing valve models, the new STS models include several nonfatal complications in addition to mortality.
Methods. Using STS data from 2002 to 2006, isolated valve surgery risk models were developed for operative mortality, permanent stroke, renal failure, prolonged ventilation (> 24 hours), deep sternal wound infection, reoperation for any reason, a major morbidity or mortality composite endpoint, prolonged postoperative length of stay, and short postoperative length of stay. The study population consisted of adult patients who underwent one of three types of valve surgery: isolated aortic valve replacement (n = 67,292), isolated mitral valve replacement (n = 21,229), or isolated mitral valve repair (n = 21,238). The population was divided into a 60% development sample and a 40% validation sample. After an initial empirical investigation, the three surgery groups were combined into a single logistic regression model with numerous interactions to allow the covariate effects to differ across these groups. Variables were selected based on a combination of automated stepwise selection and expert panel review.
Results. Unadjusted operative mortality (in-hospital regardless of timing, and 30-day regardless of venue) for all isolated valve procedures was 3.4%, and unadjusted in-hospital morbidity rates ranged from 0.3% for deep sternal wound infection to 11.8% for prolonged ventilation. The number of predictors in each model ranged from 10 covariates in the sternal infection model to 24 covariates in the composite mortality plus morbidity model. Discrimination as measured by the c-index ranged from 0.639 for reoperation to 0.799 for mortality. When patients in the validation sample were grouped into 10 categories based on deciles of predicted risk, the average absolute difference between observed versus predicted events within these groups ranged from 0.06% for deep sternal wound infection to 1.06% for prolonged postoperative stay.
Conclusions. The new STS risk models for valve surgery include mitral valve repair as well as multiple endpoints other than mortality. Model coefficients are provided and an online risk calculator is publicly available from The Society of Thoracic Surgeons website.

ID NATIONAL DATABASE; MORTALITY-RATES; OUTCOMES; PREDICTION; PROGRAM; CURVE
AB Background. The first version of The Society of Thoracic Surgeons National Adult Cardiac Surgery Database (STS NCD) was developed nearly 2 decades ago. Since its inception, the number of participants has grown dramatically, patient acuity has increased, and overall outcomes have consistently improved. To adjust for these and other changes, all STS risk models have undergone periodic revisions. This report provides a detailed description of the 2008 STS risk model for coronary artery bypass grafting surgery (CABG).
Methods. The study population consisted of 774,881 isolated CABG procedures performed on adult patients aged 20 to 100 years between January 1, 2002, and December 31, 2006, at 819 STS NCD participating centers. This cohort was randomly divided into a 60% training (development) sample and a 40% test (validation) sample. The development sample was used to identify predictor variables and estimate model coefficients. The validation sample was used to assess model calibration and discrimination. Model outcomes included operative mortality, renal failure, stroke, reoperation for any cause, prolonged ventilation, deep sternal wound infection, composite major morbidity or mortality, prolonged length of stay (> 14 days), and short length of stay (< 6 days and alive). Candidate predictor variables were selected based on their availability in versions 2.35, 2.41, and 2.52.1 of the STS NCD and their presence in (or ability to be mapped to) version 2.61. Potential predictor variables were screened for overall prevalence in the study population, missing data frequency, coding concerns, bivariate relationships with outcomes, and their presence in previous STS or other CABG risk models. Supervised backwards selection was then performed with input from an expert panel of cardiac surgeons and biostatisticians. After successfully validating the fit of the models, the development and validation samples were subsequently combined, and the final regression coefficients were estimated using the overall combined (development plus validation) sample.
Results. The c-index for the mortality model was 0.812, and the c-indices for other endpoints ranged from 0.653 for reoperation to 0.793 for renal failure in the validation sample. Plots of observed versus predicted event rates revealed acceptable calibration in the overall population and in numerous subgroups. When patients were grouped into categories of predicted risk, the absolute difference between the observed and expected event rates was less than 1.5% for each endpoint. The final model intercept and coefficients are provided.
Conclusions. New STS risk models have been developed for CABG mortality and eight other endpoints. Detailed descriptions of model development and testing are provided, together with the final algorithm. Overall model performance is excellent.

AB Background. Since 1999, The Society of Thoracic Surgeons (STS) has published two risk models that can be used to adjust the results of valve surgery combined with coronary artery bypass graft surgery (CABG). The most recent was developed from data for patients who had surgery between 1994 and 1997 using operative mortality as the only endpoint. Furthermore, this model did not specifically consider mitral valve repair plus CABG, an increasingly common procedure. Consistent with STS policy of periodically updating and improving its risk models, new models for valve surgery combined with CABG have been developed. These models specifically address both perioperative morbidity and mitral valve repair, and they are based on contemporary data.
Methods. The final study population consisted of 101,661 procedures, including aortic valve replacement (AVR) plus CABG, mitral valve replacement (MVR) plus CABG, or mitral valve repair (MVRepair) plus CABG between January 1, 2002, and December 31, 2006. Model outcomes included operative mortality, stroke, deep sternal wound infection, reoperation, prolonged ventilation, renal failure, composite major morbidity or mortality, prolonged postoperative length of stay, and short postoperative length of stay. Candidate variables were screened for frequency of missing data, and imputation techniques were used where appropriate. Stepwise variable selection was employed, supplemented by advice from an expert panel of cardiac surgeons and biostatisticians. Several variables were forced into models to insure face validity (eg, atrial fibrillation for the permanent stroke model, sex for all models). Based on preliminary analyses of the data, a single model was employed for valve plus CABG, with indicator variables for the specific type of procedure. Interaction terms were included to allow for differential impact of predictor variables depending on procedure type. After validating the model in the 40% validation sample, the development and validation samples were then combined, and the final model coefficients were estimated using the overall 100% combined sample. The final logistic regression model was estimated using generalized estimating equations to account for clustering of patients within institutions.
Results. The c-index for mortality prediction for the overall valve plus CABG population was 0.75. Morbidity model c-indices for specific complications (permanent stroke, renal failure, prolonged ventilation > 24 hours, deep sternal wound infection, reoperation for any reason, major morbidity or mortality composite, and prolonged postoperative length of stay) for the overall group of valve plus CABG procedures ranged from 0.622 to 0.724, and calibration was excellent.
Conclusions. New STS risk models have been developed for heart valve surgery combined with CABG. These are the first valve plus CABG models that also include risk prediction for individual major morbidities, composite major morbidity or mortality, and short and prolonged length of stay.

AB The large variability (7% to 100%) in previously reported rates of receptor tyrosine kinase KIT expression in Merkel cell carcinoma (MCC) may be owing to the use of heat-induced epitope retrieval. High frequency of reported KIT reactivity by immunohistochemistry (IHC) in part prompted the initiation of a phase 2 clinical trial of imatinib mesylate (Gleevec, Novartis Pharmaceuticals, East Hanover, NJ) for the treatment of advanced MCC. Our experience has been that a small number of MCCs (12.5%) are positive for KIT by IHC. We also found a higher rate of apparently KIT-positive MCCs (75%) using heat-induced epitope retrieval. Our anecdotal experience with the use of imatinib mesylate has been disappointing. As IHC detection of KIT expression does not correlate with the presence of KIT-activating mutations, protein expression as tested by IHC should not be used to determine if patients would respond to imatinib mesylate. Indeed, our review of the literature and the apparent lack of efficacy of imatinib mesylate for MCC in a recent phase 2 trial suggest a minor role for KIT signaling in MCC tumorigenesis.

AB Background: Although cigarette smokers are at increased risk of developing multiple sclerosis (MS), the effect of smoking on the progression of MS remains uncertain.
Objective: To establish the relationship between cigarette smoking and progression of MS using clinical and magnetic resonance imaging outcomes
Design: Cross-sectional survey and longitudinal follow-up for a mean of 3.29 years, ending January 15, 2008.
Setting: Partners MS Center (Boston, Massachusetts), a referral center for patients with MS.
Patients: Study participants included 1465 patients with clinically definite MS (25.1% men), with mean (range) age at baseline of 42.0 (16-75) years and disease duration of 9.4 (0-50.4) years. Seven hundred eighty patients (53.2%) were never-smokers, 428 (29.2%) were ex-smokers, and 257 (17.5%) were current smokers.
Main Outcome Measures: Smoking groups were compared for baseline clinical and magnetic resonance imaging characteristics as well as progression and sustained progression on the Expanded Disability Status Scale at 2 and 5 years and time to disease conversion to secondary progressive MS. In addition, the rate of on-study change in the brain parenchymal fraction and T2 hyperintense lesion volume were compared. Results: Current smokers had significantly worse disease at baseline than never-smokers in terms of Expanded Disability Status Scale score (adjusted P < .001), Multiple Sclerosis Severity Score (adjusted P < .001.), and brain parenchymal fraction (adjusted P = .004). In addition, current smokers were significantly more likely to have primary progressive MS (adjusted odds ratio, 2.41; 95% confidence interval, 1.09-5.34). At longitudinal analyses, MS in smokers progressed from relapsing-remitting to secondary progressive disease faster than in never-smokers (hazard ratio for current smokers vs never-smokers, 2.50; 95% confidence interval, 1.42-4.41). In addition, in smokers, the T2-weighted lesion volume increased faster (P = .02), and brain parenchymal fraction decreased faster (P = .02).
Conclusion: Our data suggest that cigarette smoke has an adverse influence on the progression of MS and accelerates conversion from a relapsing-remitting to a progressive course.

ID CEREBELLAR PATHOLOGY
AB Background: The progressive myoclonic epilepsies (PMEs) are a disparate group of syndromes whose common features include disabling myoclonus, progressive cognitive decline, and seizures, typically with a relentless deterioration over time.
Objective: To report a novel PME syndrome.
Design: Case report.
Setting: Epilepsy service in a tertiary care urban medical center.
Patient: A 24-year-old man with progressive myoclonus, seizures, and unique features of preserved intellect and demyelinating peripheral neuropathy.
Main Outcome Measure: Detailed clinical assessment, electrophysiologic studies, and survey of the literature.
Results: We characterize an unusual PME phenotype with unique features of preserved intellect and electrophysiologic evidence of a generalized demyelinating peripheral neuropathic condition. An extensive diagnostic evaluation did not reveal an underlying cause, and a literature survey did not identify other, similar clinical reports.
Conclusion: We describe a novel PME syndrome with preserved intellect and demyelinating peripheral neuropathy.

AB Objective: To determine the effect of a topical antagonist to the chemokine receptor 2 (CCR2) in a murine model of dry eye disease.
Methods: The effects of a topical CCR2 antagonist and a vehicle control treatment were studied in murine dry eyes. A controlled environment chamber induced dry eye by exposing mice to high-flow desiccated air. Corneal fluorescein staining and enumeration of corneal CD11b(+) and conjunctival CD3(+) T cells were performed in the different groups. Real-time polymerase chain reaction was performed to quantify expression of different inflammatory cytokine transcripts in the cornea and conjunctiva.
Results: Eyes receiving the formulation containing CCR2 antagonist showed a significant decrease in corneal fluorescein staining and decreased infiltration of corneal CD11b(+) cells and conjunctival T cells compared with the vehicle-treated and untreated dry eye groups. The CCR2 antagonist also significantly decreased messenger RNA expression levels of interleukins 1 alpha and 1 beta in the cornea, and tumor necrosis factor alpha and interleukin 1 beta in the conjunctiva.
Conclusion: Topical application of CCR2 antagonist is associated with significant improvement in dry eye disease and is reflected by a decrease in inflammation at the clinical, molecular, and cellular levels.

AB Impact of surface type, wheelchair weight, and axle position on wheelchair propulsion by novice older adults.
Objective: To examine the impact of surface type, wheelchair weight, and rear axle position on older adult propulsion biomechanics.
Design: Crossover trial.
Setting: Biomechanics laboratory.
Participants: Convenience sample of 53 ambulatory older adults with minimal wheelchair experience (65-87y); men, n=20; women, n=33.
Intervention: Participants propelled 4 different wheelchair configurations over 4 surfaces: tile, low carpet, high carpet, and an 8% grade ramp (surface, chair order randomized). Chair configurations included (1) unweighted chair with an ante axle position, (2) 9.05kg weighted chair with an anterior axle position, (3) unweighted chair with a posterior axle position (Delta 0.08m), and (4) 9.05kg weighted chair with a posterior axle position (Delta 0.08m). Weight was added to a titanium folding chair, simulating the weight difference between very light and depot wheelchairs. Instrumented wheels measured propulsion kinetics.
Main Outcome Measures: Average self-selected velocity, push frequency, stroke length, peak resultant and tangential force.
Results: Velocity decreased as surface rolling resistance or chair weight increased. Peak resultant and tangential forces increased as chair weight increased, as surface resistance increased, and with a posterior axle position. The effect of a posterior axle position was greater on high carpet and the ramp. The effect of weight was constant, but was more easily observed on high carpet and ramp. The effects of axle position and weight were independent of one another.
Conclusion: Increased surface resistance decreases selfselected velocity and increases peak forces. Increased weight decreases self-selected velocity and increases forces. Anterior axle positions decrease forces, more so on high carpet. The effects of weight and axle position are independent. The greatest reductions in peak forces occur in lighter chairs with anterior axle positions.

AB Imaging approaches that visualize molecular targets rather than anatomic structures aim to illuminate vital molecular and cellular aspects of atherosclerosis biology in vivo. Several such molecular imaging strategies stand ready for rapid clinical application. This review describes the growing role of in vivo optical molecular imaging in atherosclerosis and highlights its ability to visualize atheroma inflammation, calcification, and angiogenesis. In addition, we discuss advances in multimodality probes, both in the context of multimodal imaging as well as multifunctional, or "theranostic," nanoparticles. This review highlights particular molecular imaging strategies that possess strong potential for clinical translation. (Arterioscler Thromb Vasc Biol. 2009; 29: 1017-1024.)

AB Objective-Resistin is associated with inflammation and insulin resistance and exerts direct effects on myocardial cells including hypertrophy and altered contraction. We investigated the association of serum resistin concentrations with risk for incident heart failure (HF) in humans.
Methods and Results-We studied 2902 older persons without prevalent HF (age, 73.6 +/- 2.9 years; 48.1% men; 58.8% white) enrolled in the Health, Aging, and Body Composition (Health ABC) Study. Correlation between baseline serum resistin concentrations (20.3 +/- 10.0 ng/mL) and clinical variables, biochemistry panel, markers of inflammation and insulin resistance, adipocytokines, and measures of adiposity was weak (all rho <0.25). During a median follow-up of 9.4 years, 341 participants (11.8%) developed HF. Resistin was strongly associated with risk for incident HF in Cox proportional hazards models controlling for clinical variables, biomarkers, and measures of adiposity (HR, 1.15 per 10.0 ng/mL in adjusted model; 95% CI, 1.05 to 1.27; P = 0.003). Results were comparable across sex, race, diabetes mellitus, and prevalent and incident coronary heart disease subgroups. In participants with available left ventricular ejection fraction at HF diagnosis (265 of 341; 77.7%), association of resistin with HF risk was comparable for cases with reduced versus preserved ejection fraction.
Conclusions-Serum resistin concentrations are independently associated with risk for incident HF in older persons. (Arterioscler Thromb Vasc Biol. 2009; 29: 1144-1149.)

AB Objective. Most of the Borrelia burgdorferi genotypes have been isolated from erythema migrans (EM) skin lesions in patients with Lyme disease. OspC type K strains, which are 16S-23S ribosomal RNA intergenic spacer type 2 (RST2) strains, are most commonly recovered, but a higher percentage of OspC type A strains (RST1), the next most commonly recovered type, is detectable in blood. The goal of this study was to determine the B burgdorferi genotypes in the joints of patients with Lyme arthritis.
Methods. Joint fluid samples from 124 patients seen over a 30-year period were analyzed for OspC types by semi-nested polymerase chain reaction (PCR) and sequencing, and for RSTs by nested PCR and restriction fragment length polymorphism analysis. These results were correlated with clinical outcome.
Results. OspC and RST genotypes were identified in 49 of the 124 joint fluid samples (40%). In these 49 samples, OspC type K strains (RST2) were identified in 21 samples (43%), OspC type A strains (RST1) were identified in 11 samples (22%), and 8 other OspC types and all 3 RSTs were identified among the remaining 17 samples (35%). However, among the 17 patients who had been treated with antibiotics according to current guidelines, all 7 patients who were infected with RST1 strains had antibiotic-refractory arthritis, compared with 4 of 6 patients infected with RST2 strains and only I of 4 infected with RST3 strains (P = 0.03).
Conclusion. Most of the B burgdorferi genotypes, particularly OspC type K (RST2), were identified in the joint fluid of patients with Lyme arthritis, and the genotype frequencies found in joints reflected those in EM skin lesions. However, RST1 strains were most frequent in patients with antibiotic-refractory arthritis. Our results help to further the understanding of the differential pathogenicity of strains of B burgdorferi.

AB It is known that human benign prostatic hyperplasia might arise from an estrogen/androgen (E/T) imbalance. We studied the response of castrated rat prostate to different ratios of circulating E/T. The castrated male Wistar rats were randomly injected with E/T at different ratios for 4 weeks. The prostates of E/T (1:100) group showed a distinct prostatic hyperplasia response by prostatic index, hematoxylin and eosin staining, and quantitative immunohistochemical analysis of alpha-smooth muscle actin (SMA). In this group, cells positive for Vimentin, nonmuscle myosin heavy chain (NMMHC) and proliferating cell nuclear antigen (PCNA) increased in the stroma and epithelium. Furthermore, the mRNA levels of smooth muscle myosin heavy chain (SMMHC) and NMMHC increased. So E/T at a ratio of 1:100 can induce a stromal hyperplastic response in the prostate of castrated rats. The main change observed was an increase of smooth muscle cells, whereas some epithelial changes were also seen in the rat prostates.

AB Autophagy is implicated in many functions of mammalian cells such as organelle recycling, survival and differentiation, and is essential for the maintenance of T and B lymphocytes. Here, we demonstrate that autophagy is a constitutive process during T cell development. Deletion of the essential autophagy genes Atg5 or Atg7 in T cells resulted in decreased thymocyte and peripheral T cell numbers, and Atg5-deficient T cells had a decrease in cell survival. We employed functional-genetic and integrative computational analyses to elucidate specific functions of the autophagic process in developing T-lineage lymphocytes. Our whole-genome transcriptional profiling identified a set of 699 genes differentially expressed in Atg5-deficient and Atg5-sufficient thymocytes (Atg5-dependent gene set). Strikingly, the Atg5-dependent gene set was dramatically enriched in genes encoding proteins associated with the mitochondrion. In support of a role for autophagy in mitochondrial maintenance in T lineage cells, the deletion of Atg5 led to increased mitochondrial mass in peripheral T cells. We also observed a correlation between mitochondrial mass and Annexin-V staining in peripheral T cells. We propose that autophagy is critical for mitochondrial maintenance and T cell survival. We speculate that, similar to its role in yeast or mammalian liver cells, autophagy is required in T cells for the removal of damaged or aging mitochondria and that this contributes to the cell death of autophagy-deficient T cells.

AB Stress and alcohol abuse are co-related. Acute alcohol is anxiolytic and stress is cited as a factor in relapse to alcohol use. A primary mediator of the stress response is the neuropeptide corticotropin-releasing factor (CRF). The CRF family of endogenous ligands includes urocortin 3 (Ucn 3), which binds selectively to the CRF type 2 receptor and has been implicated in ethanol consumption in dependent and withdrawing rats. The objective of this study was to examine the effect of Ucn 3, delivered centrally to nondependent mice, on limited-access ethanol consumption. Adult MUM mice were trained to self-administer 10% ethanol during daily, 2-h limited-access sessions, using lickometers to assess drinking patterns for both ethanol and water. Sterile saline or 0.3, 1, or 3 nmol of Ucn 3 was microinjected into the lateral ventricle immediately before the limited-access session in a within-subjects design. There was a significant decrease in ethanol (both ml and g/kg), but not water, intake following Ucn 3 treatment, explained by a change in size of the largest lick run. Food intake at both 2 h and 24 h after injection was statistically unaffected by Ucn 3 administration. These results establish a role for CRF type 2 receptors in a nondependent mouse model of ethanol self-ad ministration.

AB Sodium-proton exchanger type 1 (NHE-1) is ubiquitously expressed, is activated by numerous growth factors, and plays significant roles in regulating intracellular pH and cellular volume, proliferation and cytoskeleton. Despite its importance, little is known about its regulation in renal glomerular podocytes. In the current work, we studied the regulation of NHE-1 activity by the epidermal growth factor receptor (EGFR) in cultured podocytes. RT-PCR demonstrated mRNAs for NHE-1 and NHE-2 in differentiated podocytes, as well as for EGFR subunits EGFR/ErbB1, Erb3, and ErbB4. EGF induced concentration-dependent increases in proton efflux in renal podocytes as assessed using a Cytosensor microphysiometer, were diminished in the presence of 5-(N-methyl-N-isobutyl) amiloride or in a sodium-free solution. Furthermore, pharmacological inhibitors of Janus kinase (Jak2) and calmodulin (CaM) attenuated EGF-induced NHE-1 activity. Co-immunoprecipitation studies determined that EGF induced formation of complexes between Jak2 and CaM, as well as between CaM and NHE-1. In addition, EGF increased levels of tyrosine phosphorylation of Jak2 and CaM. The EGFR kinase inhibitor, AG1478, blocked activation of NHE-1, but did not block EGF-induced phosphorylation of Jak2 or CaM. These results suggest that EGF induces NHE-1 activity in podocytes through two pathways: (1) EGF -> EGFR -> Jak2 activation (independent of EGFR tyrosine kinase activity) -> tyrosine phosphorylation of CaM -> CaM binding to NHE-1 -> conformational change of NHE-1 -> activation of NHE-1; and (2) EGF -> EGFR -> EGFR kinase activation -> association of CaM with NHE-1 (independent of Jak2) -> conformational change of NHE-1 -> activation of NHE-1.

AB Currently, no agents are approved by the United States Food and Drug Administration (FDA) for either prevention or treatment of acute graft-versus-host disease (aGVHD). Formal precedents establishing a comparative basis for assessing the efficacy and safety of new investigational agents are still lacking. As a step toward addressing this problem, a panel of experts met on 2 occasions to reach consensus on recommendations for terminology describing a clinically meaningful primary endpoint in studies assessing treatment for aGVHD. The panel recommended terminology for "very good partial response" (VGPR) that includes both diagnostic and functional criteria. The central hypothesis leading to this proposal is that the potential harm of giving more treatment than needed to produce or maintain complete response exceeds the harm of slight under-treatment that may be associated with less than complete response. VGPR clearly cannot be used as the sole outcome measure in GVHD treatment trials, and must be considered in the context of survival and safety. The proposed use of VGPR as the primary endpoint in GVHD treatment trials will remain provisional until its use has been validated through experience.

AB Rare reports of splenic rupture have been associated with filgrastim treatment during peripheral blood progenitor cell (PBPC) mobilization in allogeneic donors. We performed a prospective study of spleen volume change in 309 normal donors who received filgrastim according to local institutional practices. Splenic assessments consisted of ultrasonography and clinical examination at baseline and on the first day of leukapheresis in 304 donors. Of these, 90 donors were also examined 2 and 4 days after the first leukapheresis and 7 days after the last leukapheresis. Median spleen volume increased 1.47-fold (range: 0.63 to 2.60) on the first leukapheresis day and declined to near pretreatment levels at 7 days after last leukapheresis. Nine percent of donors had >= 2-fold increase in splenic volume. Spleen palpability did not correlate with change in spleen volume. No donors experienced a splenic rupture. There was no correlation between change in spleen volume and filgrastim dosage, number of doses/day, peak absolute neutrophil count (ANC), CD34(+) yield, or donor baseline weight. Most donors experienced >= 1 adverse event, with 6 donors reporting serious adverse events. We conclude that the increase in splenic volume during PBPC mobilization in donors was transient, and that filgrastim was well tolerated in this study. This trial was registered at www.ClinicalTrials.gov as NCT00115128.

AB Previous studies have shown that adding sirolimus to a tacrolimus/mini-methotrexate regimen (Tac/Sir/MTX) as graft-versus-host disease (GVHD) prophylaxis produces low rates of acute GVHD (aGVHD) after reduced-intensity conditioning (RIC) allogeneic stem cell transplantation (SCT). To assess whether posttransplantation methotrexate MTX can be safely eliminated altogether, we conducted a prospective clinical trial testing the combination of T and Sir alone (tac/sir) as GVHD prophylaxis after RIC SCT from matched related donors. We compared the results with patients who received (Tac/Sir/MTX) as GVHD prophylaxis after RIC SCT from matched related donors in a previous prospective study. Patients in both groups received i.v. fludarabine (Flu) 30 mg/m(2)/day and i.v. busulfan (Bu) 0.8 mg/kg/day on days -5 to -2 as conditioning, followed by transplantation of unmanipulated filgrastim-mobilized peripheral blood stem cells (PBSCS). After transplantation, patients in both groups received Tac and Sir orally starting on day -3, with doses adjusted to achieve trough serum levels of 5 to 10 ng/mL and 3 to 12 ng/mL, respectively. The patients in the Tac/Sir/MTX group also received mini-MTX therapy (S mg/m(2) i.v.) on days + 1, + 3, and + 6. Filgrastim 5 mu g/kg/day s.c. was started on day + I and continued until neutrophil engraftment. Twenty-nine patients received the Tac/Sir regimen, and 46 patients received the Tac/Sir/MTX regimen. The 2 groups were balanced in terms of age, sex, and disease characteristics. Engraftment was brisk and donor chimerism after transplantation robust in both groups. The cumulative incidence of grade II-IV aGVHD was similar in the 2 groups (17% for Tac/Sir versus 11% for Tac/Sir/MTX; P = .46). There also were no differences between the 2 groups in cumulative incidence of extensive chronic GVHD (cGVHD), treatment-related mortality (TRM), disease relapse, or survival. The Tac/Sir combination for GVHD prophylaxis is well tolerated and associated with a low incidence of aGVHD in matched related donor RIC SCT The omission of mini-MTX from the Tac/Sir GVHD prophylaxis regimen appears to have no adverse effect on the development of aGVHD.

AB BACKGROUND: Although thyroid disorders are present in approximately 3%, of pregnant women, little is known about the association between maternal thyroid disease and birth defects. METHODS: We assessed the association between maternal thyroid disease, thyroid medication use, and 38 types of birth defects among 14,067 cases and 5875 controls in the National Birth Defects Prevention Study, a multisite, population-based, case-control study. Infants in this study were born between October 1997 and December 2004. Information on exposures including maternal diseases and use of medications was collected by telephone interview. RESULTS: We found statistically significant associations between maternal thyroid disease and left ventricular outflow tract obstruction heart defects (1.5; 95%, CI, 1.0-2.3), hydrocephaly (2.9; 951, CI, 1.6-5.2), hypospadias (1.6; 95%, CI, 1.0-2.5), and isolated anorectal atresia (2.4; 95%, CI, 1.2-4.6). Estimates for the association between periconceptional use of thyroxine and specific types of birth defects were similar to estimates for any thyroid disease. Given that antithyroid medication use was rare, we could not adequately assess risks for their use for most case groups. CONCLUSIONS: Our results are consistent with the positive associations between maternal thyroid disease or thyroid medication use and both hydrocephaly and hypospadias observed in some previous studies. New associations with left ventricular outflow tract obstruction heart defects and anorectal atresia may be chance findings. Birth Defects Research (Part A) 55:621-628, 2009.

AB OBJECTIVES
To report our original experience in patients in whom bacille Calmette-Guerin (BCG) therapy has failed for T1 bladder cancer with subsequent progression to T2 disease treated with chemo-radiotherapy, as the management of recurrent high-grade T1 bladder cancer after failed BCG therapy is challenging, and radical cystectomy is the standard treatment because there are no well established second-line bladder-preserving therapies.
PATIENTS AND METHODS
From 1988 to 2002, 18 patients with T2 recurrence after failure of BCG therapy for T1 bladder cancer were treated with chemo-radiotherapy at the authors' institution. Patients received a visibly complete transurethral resection of the bladder tumour (TURBT) and concurrent chemo-radiotherapy with a mid-treatment evaluation after 40 Gy. Patients with less than a complete response had a prompt cystectomy; the others completed radiotherapy to 64-65 Gy. The primary treatment outcome was freedom from cystectomy due to recurrence not treatable by conservative measures; secondary outcomes included disease-specific (DSS) and overall survival (OS).
RESULTS
With a median follow-up of 7.0 years, only one patient had persistent tumour at re-staging TURBT and had an immediate cystectomy. Of the remaining 17 patients, 10 (59%) were free of any bladder recurrence. The actuarial 7-year DSS and OS were 70% and 58%, respectively. At 7 years, 54% of patients were alive with intact bladders and free of invasive recurrence.
CONCLUSIONS
In this study we specifically evaluated patients with apparently small muscle-invasive recurrences after BCG treatment for T1 bladder cancer. Selective bladder preservation with chemo-radiotherapy is possible, with low morbidity and a high chance of long-term bladder control. If successful in treating T2 recurrences after BCG therapy, it now seems timely to critically evaluate chemo-radiotherapy as an alternative to immediate cystectomy in the management of patients with T1 recurrences after BCG.

AB Runt-related ( RUNX) transcription factors are evolutionarily conserved regulators of a number of developmental mechanisms. RUNX proteins often control the balance between proliferation and differentiation and alterations of their functions are associated with different types of cancer and other human pathologies. Moreover, RUNX factors control important steps during the developmental acquisition of mature phenotypes. A number of investigations are beginning to shed light on the involvement of RUNX family members in the development of the nervous system. This review summarizes recent progress in the study of the roles of mammalian RUNX proteins during the differentiation of sensory and motor neurons in the peripheral and central nervous system, respectively. The implications of those findings for RUNX-mediated regulation of hematopoietic development will also be discussed. (C) 2009 Elsevier Inc. All rights reserved.

AB Background: Bone mineral density (BMD) is lower in amenorrheic athletes (AA) compared with eumenorrheic athletes (EA). Decreased energy availability and altered levels of appetite regulating hormones (ghrelin and leptin) in AA contribute to hypogonadism, an important Cause of low BMD. The role of other nutritionally regulated hormones such as peptide YY (PYY) and adiponectin in mediating gonadal status and bone metabolism remains to be determined.
Objectives: Our objective was to determine whether PYY and adiponectin are higher in AA Compared with EA and contribute to hypogonadism and impaired bone metabolism in AA.
Methods: We determined PYY and adiponectin in 16 AA, 15 EA and 16 non-athletic controls 12-18 years old, and other nutritionally dependent hormones including ghrelin, leptin and IGF-1. We also measured testosterone, estradiol, PINP and NTX (markers of bone formation and resorption) and BMD.
Results: PYY was higher in AA than EA (111 +/- 52 vs. 61 +/- 29 pg/ml, p<0.05), whereas adiponectin did not differ between groups. Although activity scores did not differ, BMI was lower in AA than EA and a larger proportion (62.5% vs. 6.7%) reported disordered eating, indicating lower energy availability. PYY and adiponectin were independent predictors of testosterone in a regression model (p = 0.01 and 0.04), but did not predict estradiol. PYY, but not adiponectin, was an independent and negative predictor of PINP (p = 0.002) and lumbar bone mineral apparent density Z-scores (p = 0.045) in this model.
Conclusion: High PYY levels (but not adiponectin) differentiate AA from EA, and may be an important factor contributing to low bone density in athletes. (C) 2009 Elsevier Inc. All rights reserved.

AB In this work, we apply Granger causality analysis to high spatiotemporal resolution intracranial EEG (iEEG) data to examine how different components of the left perisylvian language network interact during spoken language perception. The specific focus is on the characterization of serial versus parallel processing dependencies in the dominant hemisphere dorsal and ventral speech processing streams. Analysis of iEEG data from a large, 64-electrode grid implanted over the left perisylvian region in a single right-handed patient showed a consistent pattern of direct posterior superior temporal gyros influence over sites distributed over the entire ventral pathway for words, non-words, and phonetically ambiguous items that could be interpreted either as words or non-words. For the phonetically ambiguous items, this pattern was overlayed by additional dependencies involving the inferior frontal gyrus, which influenced activation measured at electrodes located in both ventral and dorsal stream speech structures. Implications of these results for understanding the functional architecture of spoken language processing and interpreting the role of the posterior superior temporal gyros in speech perception are discussed.

AB The predictive role of the degree of endocrine responsiveness to preoperative chemotherapy (PCT) is unclear. We reviewed pretreatment biopsies of 553 patients with locally advanced breast cancer who were treated with PCT. The incidence of pathological complete remission (pCR) and outcome were assessed with respect to the degree of estrogen (ER) and progesterone receptor (PgR) expression (ER and PgR absent, vs. ER or PgR 0-49%, vs. ER and PgR a parts per thousand yen50% of the cells positive). A statistically significant higher pCR rate was observed at the multivariate analysis for patients with ER and PgR absent tumors (17.7%) versus patients with tumors expressing high ER and PgR (0%) (OR 14.4 P < 0.001). Despite the higher incidence of pCR, a statistically significant worse disease-free survival (DFS), and overall survival (OS) was observed for patients with ER and PgR absent tumors versus patients with tumors expressing high ER and PgR (HR 6.4, 95% CI 3.5-11.6, for DFS; HR 3.6 95% CI 2.4-5.6 for OS). Response and outcome after PCT are correlated with the degree of expression of steroid hormone receptors. Studies on tailored preoperative therapies are needed.

AB The Breast Cancer Family Registry is a resource for interdisciplinary and translational studies of the genetic epidemiology of breast cancer. This resource is available to researchers worldwide for collaborative studies. Herein, we report the results of testing for germline mutations in BRCA1 and BRCA2. We have tested 4,531 probands for mutations in BRCA1 and 4,084 in BRCA2. Deleterious mutations in BRCA1 and BRCA2 were identified for 9.8% of probands tested [233/4,531 (5.1%) for BRCA1 and 193/4,084 (4.7%) for BRCA2]. Of 1,385 Ashkenazi Jewish women tested for only the three founder mutations, 17.4% carried a deleterious mutation. In total, from the proband and subsequent family testing, 1,360 female mutation carriers (788 in BRCA1, 566 in BRCA2, 6 in both BRCA1 and BRCA2) have been identified. The value of the resource has been greatly enhanced by determining the germline BRCA1 and BRCA2 mutation statuses of nearly 6,000 probands.

AB BACKGROUND: We address the prognostic and predictive value of KRAS, PIK3CA and BRAF mutations for clinical outcomes in response to active agents in the treatment of metastatic colorectal cancer (mCRC).
METHODS: We determined KRAS, BRAF and PIK3CA mutations in tumours from 168 patients treated for mCRC at two institutions. All patients received 5-FU-based first-line chemotherapy and treatment outcome was analysed retrospectively.
RESULTS: KRAS, BRAF and PIK3CA mutations were present in 62 (37%), 13 (8%) and 26 (15%) cases, respectively. Multivariate analysis uncovered BRAF mutation as an independent prognostic factor for decreased survival (hazard ratio (HR) 4.0, 95% confidence interval (CI) 2.1-7.6). In addition, patients with BRAF-mutant tumours had significantly lower progression-free survival (PFS: HR 4.0, 95% CI 2.2-7.4) than those whose tumors that carried wild-type BRAF. Among 92 patients treated using chemotherapy and cetuximab as salvage therapy, KRAS mutation was associated with lack of response (P = 0.002) and shorter PFS (P = 0.09). BRAF (P = 0.0005) and PIK3CA (P = 0.01) mutations also predicted reduced PFS in response to cetuximab salvage therapy.
CONCLUSIONS: These results underscore the potential of mutational profiling to identify CRCs with different natural histories or treatment responses. The adverse significance of BRAF mutation should inform patient selection and stratification in clinical trials.

AB P>Lenalidomide gained Food and Drug Administration (FDA) approval for treatment of patients with relapsed or refractory multiple myeloma (MM) in combination with dexamethasone in June 2006. In April 2005, the FDA and patient advocacy groups requested an expanded access programme to both provide lenalidomide to patients likely to benefit and obtain additional safety information. Relapsed/refractory MM patients received lenalidomide 25 mg/d (days 1-21) and dexamethasone 40 mg/d (days 1-4, 9-12, and 17-20 of cycles 1-4; days 1-4 only from cycle 5 onwards), in 4-week cycles until disease progression, study drug discontinuation, or lenalidomide approval. Of the 1438 patients enrolled, similar to 60% were male, median age was 64 years, and 61 center dot 7% had Durie-Salmon stage III disease. Median time on study was 15 center dot 4 weeks (range: 0 center dot 1-49 center dot 1) and median dose was 25 mg. The most common adverse events (AEs) were haematological (49%), gastrointestinal (59%), and fatigue (55%). The most common grade >= 3 AEs were haematological (45%), fatigue (10%), and pneumonia (7%). The most common serious AEs were pneumonia (8%), pyrexia (4%), and deep-vein thrombosis (3%). Primary cause of death was disease progression (10%). Safety data confirmed known AEs of lenalidomide plus dexamethasone therapy in patients with relapsed/refractory MM.

valve vegetation into the left atrium through a patent foramen ovale
SO CANADIAN JOURNAL OF CARDIOLOGY

DT Editorial Material
DE Echocardiography; Infective endocarditis; Patent foramen ovale
ID COMPLICATION
AB Tricuspid valve endocarditis frequently occurs in the setting of intravenous drug use. A case of tricuspid valve endocarditis in a 37-year-old woman with a history of intravenous cocaine use is described. Transthoracic echocardiography showed extension of the tricuspid valve mass through a patent foramen ovale and into the left atrium. One week after intravenous antibiotic treatment, the mass no longer traversed the patent foramen ovale, and only two smaller tricuspid valve vegetations remained. The present case demonstrates the value of performing a complete and thorough transthoracic echocardiography to visualize and evaluate both the right- and left-sided consequences of infective endocarditis in intravenous drug users. It also serves its it useful reminder to physicians caring for such patients that right-sided endocarditis can have important left-sided complications.

AB Oxidative stress plays a dominant role in the pathogenesis of cardiac cell apoptosis in diabetic patients. Sildenafil has been demonstrated to have antioxidant effects. In this study, the effects of sildenafil on diabetes-induced cardiac cell apoptosis and the antioxidant status of diabetic mouse hearts were investigated. Diabetic mice showed lower body weight gains and heart weights compared with control mice, and sildenafil treatment did not increase these parameters in diabetic mice. Although apoptotic rates, caspase-3 enzyme activity, and malondialdehyde levels were significantly higher in diabetic mouse hearts than in controls, they were reduced in diabetic mice after sildenafil treatment. At the end of the first week, we observed no significant differences in antioxidant enzyme activities (CAT, GSH-Px, and SOD) in diabetic and control groups, whereas at the end of the second week of sildenafil treatment, antioxidant enzyme activities were higher in the diabetic group. In conclusion, our study indicated that sildenafil was beneficial to hearts of diabetic mice by reducing cardiac cell apoptosis, partially because of its antioxidant effects in the heart.

AB To identify the apoptosis genes involved in the multidrug resistant phenotype of osteosarcoma.
Multidrug resistant human osteosarcoma cell line (U-2 OS MR) and a drug sensitive parental cell line (U-2 OS) were both treated with paclitaxel and analyzed by the gene array containing 96 apoptosis associated genes. The different expression of the special apoptosis associated genes were further analyzed by Western blot in the multidrug resistant osteosarcoma cell lines (U-2 OS MR, KH OS R2) and the drug sensitive parental cell lines (U-2 OS, KH OS). One of the disregulated gene, RAIDD, was transfected into the multidrug resistant osteosarcoma cells for functional studies.
RAIDD showed signs of significant expression in the U-2 OS cells after being treated with paclitaxel (P < 0.01). However, the induction of RAIDD did not occur in U-2 OS MR cells (P = 0.2). Subsequent analysis by Western blot confirmed the deficiency of the expression of RAIDD protein in U-2 OS MR. On the contrary, the expression of RAIDD could be significantly induced by paclitaxel and doxorubicin in U-2 OS cells as both time and dosage were deciding factors. It also demonstrated the cleavage of PARP associated with RAIDD expression in U-2 OS cells, but not however in U-2 OS MR cells after being treated with paclitaxel or doxorubicin. Similar results were found in osteosarcoma multidrug resistant cell line KH OS R2 and the drug sensitive parental cell line KH OS. Furthermore, over-expression of RAIDD in multidrug resistant cell lines could possibly reverse drug resistant phenotypes.
This study indicate that impaired expression of RAIDD in drug induced apoptosis may play a role in the multidrug resistance of osteosarcoma cells.

AB Genetically engineered oncolytic herpes simplex virus-1 (HSV-1) vectors selectively replicate in tumor cells causing direct killing whereas sparing normal cells. One clinical limitation of using oncolytic HSV vectors is their attenuated growth. We hypothesized that the appropriately chosen chemotherapeutic agent combined with an oncolytic HSV could be an effective means to promote augmented prostate cancer cell killing both in vitro and in vivo. Here we have identified that G47 Delta synergizes with the microtubule-stabilizing taxane agents docetaxel and paclitaxel to enhance the in vitro killing of prostate cancer cells. In vivo efficacy studies show that when combined with docetaxel, G47 Delta could be reduced at least 10-fold. Immunoblot analysis revealed that docetaxel-induced accumulation of the phospho-specific mitotic markers op18/stathmin or histone-H3 was markedly reduced by G47 Delta, which correlated with enhanced apoptosis and required active viral replication. Furthermore, cell-cycle analysis demonstrated that in the presence of G47 Delta, the majority of 4N cells arrested in mitosis were MPM-2-negative, indicative of cells exiting mitosis prematurely. These findings suggest that G47 Delta may act in part, on mitotically blocked cells to enhance cell death, which may account for the enhanced antitumor efficacy observed in vivo.

AB The approval of a multitargeted receptor tyrosine kinase inhibitor, sorafenib, with activity against vascular endothelial growth factor receptor-2 and -3, Raf-1 and B-Raf, platelet-derived growth factor receptor-alpha and -beta, and other kinases, has ushered in the era of molecular targeted agents in advanced hepatocellular carcinoma (HCC). Sunitinib malate is an oral, multitargeted inhibitor of vascular endothelial growth factor receptor-1, -2, and -3, platelet-derived growth factor receptor-alpha and -beta, and other kinases implicated in tumor growth, angiogenesis, and metastasis. Sunitinib has been approved in metastatic renal cell carcinoma and gastrointestinal stromal tumor and is undergoing active clinical development in HCC. Early evidence of antitumor activity and a promising safety profile for this agent have emerged from single arm phase 11 trials in United States, European, and Asian patients with advanced HCC. Correlative studies of imaging and circulating biomarkers have provided insights into the potential mechanism of action of sunitinib. Additional phase II studies using either single agent or in combination with chemotherapeutic agents are ongoing, and a phase III trial comparing sunitinib and sorafenib in advanced HCC is actively accruing patients. Here, we review the current progress and future directions for the development of sunitinib in advanced HCC.

AB The technology that is used for the production and delivery of therapeutic proton beams is reviewed. Increased interest in this treatment modality has inspired a new generation of technology development and research into methods that will make proton treatment facilities more widely available (less expensive) and more efficient. Proton beam therapy has been in use for more than 40 years; it remains a treatment modality of interest because it provides a highly conformal dose distribution to a wide variety of disease sites and the potential for improving clinical outcomes. Recent advances in beam scanning technology may represent the ultimate in external beam radiotherapy dose conformality and treatment delivery efficiency. We describe how this new technology can be integrated into a proton therapy facility.

AB Proton beam therapy (PBT) has been in use for a number of decades, though interest in PBT for localized prostate cancer has grown substantially in recent years. Protons offer the theoretical potential of achieving dose escalation and decreasing toxicity by capitalizing on unique physical dose deposition characteristics to avoid normal tissue. Although it has proven effective in a number of malignancies including as a means for dose escalation in prostate cancer, there is little published clinical data to support its comparative superiority over alternative forms of conformal radiation for prostate cancer. This review article explores the current evidence and clinical experience supporting PBT for prostate cancer, the uncertainties and controversies associated with this innovative technology, its potential economic implications, and future promise.

AB Early imaging or blood biomarkers of tumor response are desperately needed to customize antiangiogenic therapy for cancer patients. Anti-vascular endothelial growth factor (VEGF) therapy can "normalize" brain tumor vasculature by decreasing vessel diameter and permeability, and thinning the abnormally thick basement membrane. We hypothesized that the extent of vascular normalization will be predictive of outcome of anti-VEGF therapy in glioblastoma. We use advanced magnetic resonance imaging methods to monitor vascular parameters and treatment response in 31 recurrent glioblastoma patients enrolled in a phase II trial of cediranib, an oral pan-VEGF receptor tyrosine kinase inhibitor. We evaluated the correlation between clinical outcome and magnetic resonance imaging-measured changes in vascular permeability/flow (i.e., K(trans)) and in microvessel volume, and the change of circulating collagen W levels, all after a single dose of cediranib. Here, we show that evaluation of biomarkers as early as after one day of anti-VEGF therapy with cediranib is predictive of response in patients with recurrent glioblastoma. Changes in K(trans) microvessel volume, and circulating collagen IV correlated with duration of overall survival and/or progression-free survival (P < 0.05). When we combined these three parameters into a "vascular normalization index," we found that it closely associated with overall survival (rho = 0.54; P = 0.004) and progression-free survival (rho = 0.6; P = 0.001). The vascular normalization index described here should be validated in randomized clinical trials. [Cancer Res 2009;69(13):5296-300]

AB beta(1) integrins play an important role in regulating cell proliferation and survival. Using small interfering RNA or an inhibitory antibody to beta(1), we show here that, in vivo, beta(1) integrins are essential for prostate cancer growth. Among the five known beta(1) integrin cytoplasmic variants, two have been shown to differentially affect prostate cell functions. The beta(1A) variant promotes normal and cancer cell proliferation, whereas the beta(1C) variant, which is down-regulated in prostate cancer, inhibits tumor growth and appears to have a dominant effect On beta(1A). To investigate the mechanism by which beta(1C) inhibits the tumorigenic potential of beta(1A), we analyzed changes in gene expression in cells transfected with either beta(1C) or beta(1A). The results show that beta(1C) expression increases the levels of an extracellular matrix protein, thrombospondin 1 (TSP1), an angiogenesis inhibitor. TSPI protein levels are increased upon beta(1C) expression in prostate cancer cells as well as in beta(1)-null GD25 cells. We show that TSPI does not affect proliferation, apoptosis, or anchorage-independent growth of prostate cancer cells. In contrast, the newly synthesized TSPI, secreted by prostate cancer cells expressing beta(1C), prevents proliferation of endothelial cells. In conclusion, our novel findings indicate that expression of the beta(1C) integrin variant in prostate glands prevents cancer progression by up-regulation of TSP1 levels and inhibition of angiogenesis.

AB Polymorphisms at 8q24 are robustly associated with prostate cancer risk. The risk variants are located in nonprotein coding regions and their mechanism has not been fully elucidated. To further dissect the function of this locus, we tested two hypotheses: (a) unannotated microRNAs (miRNA) are transcribed in the region, and (b) this region is a cis-acting enhancer. Using next generation sequencing, 8q24 risk regions were interrogated for known and novel miRNAs in histologically normal radical prostatectomy tissue. We also evaluated the association between the risk variants and transcript levels of multiple genes, focusing on the proto-oncogene, MYC. RNA expression was measured in histologically normal and tumor tissue from 280 prostatectomy specimens (from 234 European American and 46 African American patients), and paired germline DNA from each individual was genotyped for six 8q24 risk single nucleotide polymorphisms. No evidence was found for significant miRNA transcription within 8q24 prostate cancer risk loci. Likewise, no convincing association between RNA expression and risk allele status was detected in either histologically normal or tumor tissue. To our knowledge, this is one of the first and largest studies to directly assess miRNA in this region and to systematically measure MYC expression levels in prostate tissue in relation to inherited risk variants. These data will help to direct the future study of this risk locus. [Cancer Res 2009;69(13):5568-74]

AB Oncosomes have recently been described as membrane-derived microvesicles secreted by cancer cells, which transfer oncogenic signals and protein complexes across cell boundaries. Here, we show the rapid formation and secretion of oncosomes from DU145 and LNCaP human prostate cancer cells. Oncosome formation was stimulated by epidermal growth factor receptor activation and also by overexpression of membrane-targeted Akt1. Microvesicles shed from prostate cancer cells contained numerous signal transduction proteins and were capable of activating rapid phospho-tyrosine and Akt pathway signaling, and stimulating proliferation and migration, in recipient tumor cells. They also induced a stromal reaction in recipient normal cells. Knockdown of the actin nucleating protein Diaphanous Related Formin 3 (DRF3/Dia2) by RNA interference enhanced rates of oncosome formation, indicating that these structures resemble, and may be identical to, nonapoptotic membrane blebs, a feature of the amoeboid form of cell motility. Analysis of primary and metastatic human prostate tumors using 100K single nucleotide polymorphism arrays revealed a significantly higher frequency of deletion of the locus encoding DRF3 (DIAPH3) in metastatic tumors (P = 0.001) in comparison with organ-confined tumors. Fluorescence in situ hybridization confirmed increased chromosomal loss of DIAPH3 in metastatic tumors in a different cohort of patients (P = 0.006). These data suggest that microvesicles shed from prostate cancer cells can alter the tumor microenvironment in a manner that may promote disease progression. They also show that DRF3 is a physiologically relevant protein that seems to regulate this process. [Cancer Res 2009;69(13):5601-9]

AB Background: At least 12 distinct forms of amyloidosis are known to involve the heart or great vessels. Patient treatment regimens require proper subtyping of amyloid deposits in small diagnostic cardiac specimens. A growing lack of confidence in immunohistochemical staining for subtyping amyloid has arisen primarily as a result of studies utilizing immunoperoxidase staining of formalin-fixed paraffin-embedded tissue. Immunofluorescence staining on fresh frozen tissue is generally considered superior to immunoperoxidase staining for subtyping amyloid; however, this technique has not previously been reported in a series of cardiac specimens. Methods: Amyloid deposits were subtyped in 17 cardiac specimens and 23 renal specimens using an immunofluorescence panel. Results: Amyloid deposits were successfully subtyped as AL, AH, or AA amyloid by immunofluorescence in 82% of cardiac specimens and 87% of renal specimens. In all cases, the amyloid classification was in good agreement with available clinical and laboratory assessments. A cross-study analysis of 163 cases of AL amyloidosis reveals probable systemic misdiagnosis of cardiac AL amyloidosis by the immunoperoxidase technique, but not by the immunofluorescence technique. Conclusions: Amyloid deposits can be reliably subtyped in small diagnostic cardiac specimens using immunofluorescence. The practical aspects of implementing an immunofluorescence

AB Patients at high risk of arterial or venous thromboembolic events often receive chronic treatment with long-term oral anticoagulants such as warfarin. However, if these patients require an invasive procedure, they may require a temporary interruption of their warfarin therapy to minimize their bleeding risk during the procedure. As warfarin has a long half-life and an unpredictable pharmacokinetic profile, short-acting parenteral anticoagulants, such as unfractionated heparin (UFH) and low-molecular-weight heparin (LMWH), may be of benefit in protecting the patient from thromboemboli while their warfarin dose is withheld. Such "bridging therapy" has traditionally been provided in-hospital with intravenous UFH; however, recent data have suggested that LMWH may be an effective alternative, with potential cost-savings due to the ability to provide bridging therapy in the outpatient setting.

AB An approach to investigate the role of cellular senescence in organismal aging has been to abrogate signaling pathways known to induce cellular senescence and to assess the effects in mouse models of premature aging. Recently, we reported the effect of loss of function of p21, a gene implicated in p53-induced cellular senescence, in the background of the Ku80(-/-) premature aging mouse (Zhao et al., EMBO Rep 2009). Here, we provide an overview of the effects of p21 deletion in different models of premature aging.

AB Melanoma incidence has increased over the last few decades and metastatic melanoma is one of the hardest malignancies to treat. Thus, novel approaches are needed for an effective management of melanoma. Interferon-alpha 2b (IFN), an immunomodulatory cytokine commonly used in melanoma treatment, has shown marginal efficacy and often results in discontinuation of therapy due to toxicity. We earlier demonstrated that epigallocatechin-3-gallate (EGCG), the major polyphenolic constituent of green tea, caused cell cycle arrest and apoptosis of human melanoma cells via modulation in cki-cyclin-cdk machinery and Bcl-2 family proteins. This study was undertaken to determine if EGCG could enhance the anti-proliferative effects of IFN. In this study, we demonstrated that EGCG and/or IFN treatments to melanoma cells resulted in a marked (1) decrease in cell proliferation and colony formation ability, and (2) induction of apoptosis. Interestingly, the combination was found to be more effective than either of the agents alone. Further, the anti-proliferative effects of EGCG and/or IFN were accompanied with an increase in Fas protein levels and a decrease in nuclear factor NF kappa B/p65 in the nucleus as well as NF kappa B promoter activity. EGCG and/or IFN also resulted in an increase in Fas-L mediated apoptosis. Further, EGCG and/or IFN treatments resulted in a decrease in melanoma tumor growth and protein levels of proliferation marker PCNA, in athymic nude mice implanted with melanoma tumors. The combination of the two modalities demonstrated a better response than either of them alone. Our data suggest that EGCG could impart therapeutic advantage if used in conjunction with IFN.

AB Aberrant metal homeostasis may enhance the formation of reactive oxygen species and A beta oligomerization and may therefore be a contributing factor in Alzheimer's disease. This study investigated the effect of chronic high intake of dietary Zn or Cu on brain metal levels and the accumulation and solubility of A beta in vivo, using a transgenic mouse model that over expresses the C-terminal containing A beta fragment of human amyloid precursor protein but does not develop amyloid deposits. Exposure to chronic high Zn or Cu in the drinking water resulted in only slight elevations of the respective metals in the brain. Total A beta levels were unchanged although soluble A beta levels were slightly decreased, without visible plaque formation, enhanced gliosis, antioxidant upregulation or neuronal loss. This study indicates that brain metal levels are only marginally altered by long term oral exposure to extremely high Cu or Zn levels, and that this does not induce A beta-amyloid formation in human A beta expressing, amyloid-free mice, although this is sufficient to modulate A beta solubility in vivo.

AB Molecular controls over the development of the exceptional neuronal subtype diversity of the cerebral cortex are now beginning to be identified. The initial subtype fate decision early in the life of a neuron, and the malleability of this fate when the balance of key postmitotic signals is modified, reveals not only that a neuron is deterministically set on a general developmental path at its birth, but also that this program must he precisely executed during postmitotic differentiation. Here, we show that callosal projection neurons (CPN) and subcerebral projection neurons (subcerebral PN) in layer V of the neocortex share aspects of molecular identity after their birth that are progressively resolved during differentiation. The LIM-homeodomain-related genes Lmo4 and Clim1 are initially expressed by both CPN and subcerebral PN in layer V, and only during mid to late differentiation does expression of Lmo4 and Clim1 become largely segregated into distinct neuronal subtypes. This progressive postmitotic resolution of molecular identity reveals similarities and possibly shared evolutionary origin between layer V CPN and subcerebral PN, and provides insight into how and when these neuronal subtypes achieve their distinct identities during cortical development.

TI Surrogate Decision Makers' Responses to Physicians' Predictions of
Medical Futility
SO CHEST
LA English
DT Article
ID CARE; LIFE; RISKS; TEXAS; END
AB Background: Although physicians sometimes use the futility rationale to limit the use of life-sustaining treatments, little is known about how surrogate decision makers view this rationale. We sought to determine the attitudes of surrogates of patients who are critically ill toward whether physicians can predict futility and whether these attitudes predict surrogates' willingness to discontinue life support when faced with predictions of futility.
Methods: This multicenter, mixed qualitative and quantitative study took place at three hospitals in California from 2006 to 2007. We conducted semistructured interviews with surrogate decision makers for 50 patients who were critically ill and incapacitated that addressed their beliefs about medical futility and inductively developed an organizing framework to describe these beliefs. We used a hypothetical scenario with a modified time-trade-off design to examine the relationship between a patient's prognosis and a surrogate's willingness to withdraw life support. We used a mixed-effects regression model to examine the association between surrogates' attitudes about futility and their willingness to limit life support in the face of a very poor prognosis. Validation methods included the use and integration of multiple data sources, multidisciplinary analysis, and member checking.
Results: Sixty-four percent of surrogates (n = 32; 95% confidence interval [CI], 49 to 77%) expressed doubt about the accuracy of physicians' futility predictions, 32% of surrogates (n = 16; 95% CI, 20 to 47%) elected to continue life support with a < 1% survival estimate, and 18% of surrogates (n = 9; 95% CI, 9 to 31%) elected to continue treatment when the physician believed that the patient had no chance of survival. Surrogates with religious objections to the futility rationale (n = 18) were more likely to request continued life support (odds ratio, 4; 95% CI, 1.2 to 14.0; p = 0.03) than those with secular or experiential objections (n = 15; odds ratio, 0.95; 95% CI, 0.3 to 3.4; p = 0.90).
Conclusions: Doubt about physicians' ability to predict medical futility is common among surrogate decision makers. The nature of the doubt may have implications for responding to conflicts about futility in clinical practice. (CHEST 2009,136.-110-117)

AB Background-Randomized trials and observational studies support using an international normalized ratio (INR) target of 2.0 to 3.0 for preventing ischemic stroke in atrial fibrillation. We assessed whether the INR target should be adjusted based on selected patient characteristics.
Methods and Results-We conducted a case-control study nested within the ATRIA cohort's 9217 atrial fibrillation patients taking warfarin to define the relationship between INR level and the odds of thromboembolism (TE; mainly stroke) and of intracranial hemorrhage (ICH) relative to INR 2.0 to 2.5. We identified 396 TE cases and 164 ICH cases during follow-up. Each case was compared with 4 randomly selected controls matched on calendar date and stroke risk factors using matched univariable analyses and conditional logistic regression. We explored modification of the INR-outcome relationships by the following stroke risk factors: prior stroke, age, and CHADS(2) risk score. Overall, the odds of TE were low and stable above INR 1.8. Compared with INR 2.0 to 2.5, the relative odds of TE increased strikingly at INR <1.8 (eg, odds ratio, 3.72; 95% CI, 2.67 to 5.19, at INR 1.4 to 1.7). The odds of ICH increased markedly at INR values >3.5 (eg, odds ratio, 3.56; 95% CI: 1.70 to 7.46, at INR 3.6 to 4.5). The relative odds of ICH were consistently low at INR <3.6. There was no evidence of lower ICH risk at INR levels <2.0. These patterns of risk did not differ substantially by history of stroke, age, or CHADS2 risk score.
Conclusions-Our results confirm that the current standard of INR 2.0 to 3.0 for atrial fibrillation falls in the optimal INR range. Our findings do not support adjustment of INR targets according to previously defined stroke risk factors. (Circ Cardiovasc Qual Outcomes. 2009;2:297-304.)

AB Background-COURAGE compared outcomes in stable coronary patients randomized to optimal medical therapy plus percutaneous coronary intervention (PCI) versus optimal medical therapy alone.
Methods and Results-Angiographic data were analyzed by treatment arm, health care system (Veterans Administration, US non-Veterans Administration, Canada), and gender. Veterans Administration patients had higher prevalence of coronary artery bypass graft surgery and left ventricular ejection fraction <= 50%. Men had worse diameter stenosis of the most severe lesion, higher prevalence of prior coronary artery bypass graft surgery, lower left ventricular ejection fraction, and more 3-vessel disease that included a proximal left anterior descending lesion (P<0.0001 for all comparisons versus women). Failure to cross rate (3%) and visual angiographic success of stent procedures (97%) were similar to contemporary practice in the National Cardiovascular Data Registry. Quantitative angiographic PCI success was 93% (residual lesion <50% in-segment) and 82% (<20% in-stent), with only minor nonsignificant differences among health care systems and genders. Event rates were higher in patients with higher jeopardy scores and more severe vessel disease, but rates were similar irrespective of treatment strategy. Within the PCI plus optimal medical therapy arm, complete revascularization was associated with a trend toward lower rate of death or nonfatal myocardial infarction. Complete revascularization was similar between genders and among health care systems.
Conclusions-PCI success and completeness of revascularization did not differ significantly by health care system or gender and were similar to contemporary practice. Angiographic burden of disease affected overall event rates but not response to an initial strategy of PCI plus optimal medical therapy or optimal medical therapy alone.

AB Background-Angina in patients with coronary artery disease is associated with worse quality of life; however, the relationship between angina frequency and resource utilization is unknown.
Methods and Results-Using data from the MERLIN-TIMI 36 trial, we assessed the association between the extent of angina after an acute coronary syndrome (ACS) and subsequent cardiovascular resource utilization among 5460 stable outpatients who completed the Seattle Angina Questionnaire at 4 months after an ACS and who were then followed for an additional 8 months. Angina frequency was categorized as none (score, 100; 2739 patients), monthly (score, 61 to 99; 1608 patients), weekly (score, 31 to 60; 854 patients), and daily (score, 0 to 30; 259 patients). Multivariable regression models evaluated the association between angina frequency and overall costs attributable to cardiovascular hospitalizations, outpatient visits and procedures, and medications. As compared with no angina, overall costs increased in a graded fashion with higher angina frequency-no angina, $2928 (reference); monthly angina, $3909 (adjusted relative cost ratio, 1.29; 95% CI, 1.21 to 1.39); weekly angina, $4558 (adjusted relative cost ratio, 1.52; 95% CI, 1.48 to 1.67); and daily angina, $6949 (adjusted relative cost ratio, 2.32; 95% CI, 2.01 to 2.69; P for trend <0.001). Differences in costs were attributable primarily to higher rates of ACS hospitalization and coronary revascularization among patients with more severe angina.
Conclusion-Among stable outpatients after ACS, a direct graded relationship was found between higher angina frequency and healthcare costs. As compared with patients without angina, patients with daily angina had a >2-fold increase in resource utilization and incremental costs of $4000 after 8 months of follow-up.

AB Background-Greater treatment intensification (TI) improves hypertension control. However, we do not know the ideal way to measure TI for research and quality improvement efforts. We compared the ability of different TI measures to predict blood pressure (BP) control.
Methods and Results-We enrolled 819 hypertensive outpatients from an urban academic hospital. Each patient was assigned 3 scores to characterize TI. The any/none score divides patients into those who had any therapy increases during the study versus none. The norm-based method models the chance of a medication increase at each visit, then scores each patient based on whether they received more or fewer medication increases than predicted. The standard-based method is similar to the norm-based method but expects a medication increase whenever the blood pressure is uncontrolled. We compared the ability of these scores to predict the final systolic blood pressure (SBP). The any/none score showed a paradoxical result: any therapy increase was associated with SBP 4.6 mm Hg higher than no increase (P < 0.001). The norm-based method score did not predict SBP in a linear fashion (P = 0.18); further investigation revealed a U-shaped relationship between the norm-based method score and SBP. However, the standard-based method score was a strong linear predictor of SBP (2.1 mm Hg lower for each additional therapy increase per 10 visits, P < 0.001). Similarly, the standard-based method predicted dichotomized blood pressure control, as measured by SBP <140 mm Hg (odds ratio, 1.30; P < 0.001).
Conclusions-Our results suggest that standard-based method is the preferred measure of treatment intensity for hypertension care. (Circ Cardiovasc Qual Outcomes. 2009;2:385-391.)

AB Background-ST2, a biomarker of cardiomyocyte stretch, powerfully predicts poor outcomes in patients with acute dyspnea, but nothing is known about associations between soluble ST2 (sST2) and cardiac structure and function, or whether sST2 retains prognostic meaning in the context of such measures.
Methods and Results-One hundred thirty-four dyspneic patients with and without decompensated heart failure had echocardiography during index admission and vital status was ascertained at 4 years. Echocardiographic and clinical correlates of sST2 as well as independent predictors of death at 4 years were identified. sST2 correlated with left ventricular end-systolic dimensions/volumes and left ventricular ejection fraction. sST2 was inversely associated with right ventricular fractional area change (rho=-0.18; P=0.046), higher right ventricular systolic pressure (rho=0.26; P=0.005), and right ventricular hypokinesis (P<0.001) and was correlated with tissue Doppler Ea wave peak velocity, but not to other indices of diastolic function. In multivariate regression, independent predictors of sST2 included right ventricular systolic pressure (t=2.29; P=0.002), left ventricular ejection fraction (t=-2.15; P=0.05) and dimensions (end systolic, t=2.57; end diastolic, t=2.98; both P<0.05), amino-terminal pro-B-type natriuretic peptide (t=3.31; P=0.009), heart rate (t=2.59; P=0.01), and presence of jugular venous distension (t=2.00; P=0.05). In a Cox proportional hazards model that included echocardiographic results and other biomarkers, sST2 independently predicted death at 4 years (hazard ratio=2.70; P=0.003).
Conclusions-Among dyspneic patients with and without acute heart failure, sST2 concentrations are associated with prevalent cardiac abnormalities on echocardiography, a more decompensated hemodynamic profile and are associated with long-term mortality, independent of echocardiographic, clinical, or other biochemical markers of risk.

AB Background-The direct consequences of a persistently increased myocardial expression of the unique matrix metallo-proteinase (MMP) membrane type-1 (MT1-MMP) on myocardial remodeling remained unexplored.
Methods and Results-Cardiac-restricted MT1-MMPexp was constructed in mice using the full-length human MT1-MMP gene ligated to the myosin heavy chain promoter, which yielded approximately a 200% increase in MT1-MMP when compared with age/strain-matched wild-type (WT) mice. Left ventricular (LV) function and geometry was assessed by echocardiography in 3-month ("young") WT (n=32) and MT1-MMPexp (n=20) mice and compared with 14-month ("middle-aged") WT (n=58) and MT1-MMPexp (n=35) mice. LV end-diastolic volume was similar between the WT and MT1-MMPexp young groups, as was LV ejection fraction. In the middle-aged WT mice, LV end-diastolic volume and ejection fraction was similar to young WT mice. However, in the MT1-MMPexp middle-aged mice, LV end-diastolic volume was approximate to 43% higher and LV ejection fraction 40% lower (both P<0.05). Moreover, in the middle-aged MT1-MMPexp mice, myocardial fibrillar collagen increased by nearly 2-fold and was associated with approximate to 3-fold increase in the processing of the profibrotic molecule, latency-associated transforming growth factor binding protein. In a second study, 14-day survival after myocardial infarction was significantly lower in middle-aged MT1-MMPexp mice.
Conclusions-Persistently increased myocardial MT1-MMP expression, in and of itself, caused LV remodeling, myocardial fibrosis, dysfunction, and reduced survival after myocardial injury. These findings suggest that MT1-MMP plays a mechanistic role in adverse remodeling within the myocardium. (Circ Heart Fail. 2009;2:351-360.)

AB Purpose: Disturbed peripheral blood B-cell homeostasis complicates certain infections and autoimmune diseases, such as HIV and systemic lupus erythematosus, but has not been reported in cancer. This study aimed to investigate whether B-cell physiology was altered in the presence of melanoma and other cancers.
Experimental Design: Flow cytometry was used to identify phenotypic differences in B cells from patients with melanoma and normal donors. In vitro stimulated 8 cells were assessed for responsiveness and also used as stimulators of allogeneic T cells in mixed lymphocyte reactions.
Results: We show B-cell dysregulation in patients with advanced melanoma (n = 26) and other solid tumors (n = 13), marked by a relative and absolute loss of CD27+ (memory) B cells and associated with an aberrant systemic plasmacytosis. Functionally, B cells from patients with melanoma inefficiently up-regulated immunoregulatory molecules and weakly secreted cytokines in response to CD40 and toll-like receptor 9 agonists. Stimulated B cells from patients induced proliferation of alloreactive CD4+ T cells, but these T cells poorly secreted IFN gamma and interleukin-2. These effects were recapitulated by using purified normal donor CD27(neg) B cells in these same assays, linking the predominance of CD27(neg) B cells in patients with the observed functional hyporesponsiveness. Indeed, B-cell dysfunction in patients strongly correlated with the extent of loss of CD27+ B cells in peripheral blood.
Conclusions: Disturbed B-cell homeostasis is a previously unrecognized feature of patients with advanced melanoma and other cancers and may represent an unanticipated mechanism of immune incompetence in cancer.

AB Purpose: Cyclin D1 and cyclin-dependent kinases (CDK) are commonly activated in colorectal cancer. The activity of cyclin D1 can be blocked by CDK inhibitors, including p27 (CDKN1B) and p21 (CDKN1A, which is induced by p53). However, prognostic significance of tumoral cyclin D1 remains uncertain, and no previous study has considered potential confounding effect of p53, p21, p27, and related molecular events [microsatellite instability (MSI), CpG island methylator phenotype, and LINE-1 hypomethylation].
Experimental Design: Among 602 colon cancer patients (stage I-IV) in two prospective cohort studies, cyclin D1 overexpression was detected in 330 (55%) tumors by immunohistochemistry. Cox proportional hazard models computed hazard ratios (HR) of colon cancer-specific and overall mortalities, adjusted for patient characteristics and tumoral molecular features, including p53, p21, p27, cyclooxygenase-2, fatty acid synthase, LINE-1 methylation, CpG island methylator phenotype, MSI, BMI, KRAS, and BRAF.
Results: Cyclin D1 overexpression was associated with a low cancer-specific mortality in Kaplan-Meier analysis (P = 0.006), and in both univariate Cox regression [unadjusted HR, 0.64; 95% confidence interval (CI), 0.47-0.88; P = 0.0063] and multivariate analyses (adjusted HR, 0.57; 95% Cl, 0.39-0.84; P = 0.0048). Similar findings were observed for an overall mortality (adjusted HR, 0.74; 95% Cl, 0.57-0.98; P = 0.036). Notably, the effect of cyclin D1 on survival might differ by MSI status (P(interaction) = 0.008). Compared with tumors that were both cyclin D1 - negative and MSI-low/microsatellite stable, the presence of either cyclin D1 or MSI-high or both seemed to confer better clinical outcome (adjusted HR point estimates, 0.10-0.65).
Conclusions: Cyclin D1 overexpression is associated with longer survival in colon cancer.

AB About one third of patients with epilepsy do not benefit from medical treatment. For these patients electroencephalographic (EEG) biofeedback is a viable alternative. EEG biofeedback, or neurofeedback, normalizes or enhances EEG activity by means of operant conditioning. While dozens of scientific reports have been published on neurofeedback for seizure disorder, most have been case series with too few subjects to establish efficacy, The purpose of this paper is to meta-analyze existing research on neurofeedback and epilepsy.
We analyzed every EEG biofeedback study indexed in MedLine, PsychInfo, and PsychLit databases between 1970 and 2005 on epilepsy that provided seizure frequency change in response to feedback. Sixty-three studies have been published, 10 of which provided enough outcome information to be included in a meta-analysis. All studies consisted of patients whose seizures were not controlled by medical therapies, which is a very important factor to keep in mind when interpreting the results. Nine of 10 studies reinforced sensorimotor rhythms (SMR) while 1 study trained slow cortical potentials (SCP). All studies reported an overall mean decreased seizure incidence following treatment and 64 out of 87 patients (74%) reported fewer weekly seizures in response to EEG biofeedback. Treatment effect was mean log (post/pre) where pre and post represent number of seizures per week prior to treatment and at final evaluation, respectively. Due to prevalence of small groups, Hedges's g was computed for effect size, As sample heterogeneity was possible (Q test, p=.18), random effects were assumed and the effect of intervention was -0.233, SE=0.057, z=-4.11, P<.001.
Based on this meta-analysis, EEG operant conditioning was found to produce a significant reduction on seizure frequency. This finding is especially noteworthy given the patient group, individuals who had been unable to control their seizures with medical treatment.

AB BACKGROUND & AIMS: It is well-established that cirrhosis negatively impacts health-related quality of life (HRQOL). However, it is less clear how to use this information in everyday clinical practice. If HRQOL predicted survival in cirrhosis, then measuring HRQOL would have important clinical implications. We sought to measure the association between HRQOL and survival in patients with cirrhosis and investigated whether the relationship between HRQOL and Survival is independent of Model for End-Stage Liver Disease (MELD). METHODS: We measured HRQOL in 156 patients with cirrhosis awaiting liver transplantation by using the Short Form Liver Disease Quality of Life instrument. We followed patients prospectively and used Cox proportional hazard models to measure the independent effect of baseline HRQOL on survival, adjusting for MELD and other covariates. RESULTS: During a mean 9-month follow-up, 26 (17%) patients died, and 30 (20%) received liver transplants. In unadjusted analysis, higher baseline HRQOL predicted lower mortality (hazard ratio, 0.96; 95% confidence interval, 0.94-0.99). Specifically, for each 1-point increase in HRQOL, there was a 4% decrease in mortality. These results did not change after adjusting for MELD scores, patient demographics, or psychosocial characteristics; the MELD score accounted for 1% of the variation in HRQOL scores (P=.18). Survival was most strongly predicted by activities of daily living, health distress, sleep disturbance, and perceived disease stigma. CONCLUSIONS: Higher HRQOL predicts lower mortality in patients with cirrhosis. This relationship is independent of MELD; MELD does not capture liver-specific HRQOL. Beyond its use as a secondary outcome in clinical trials, HRQOL could be used to predict survival of patients with advanced liver disease.

Only the 2 glycolipids, acylated cholesteryl galactoside (ACG, BbGL-I) and monogalactosyl diacylglycerol (MgaID, BbGL-II), were immunogenic. Early in the infection, 24 of 84 patients (29%) who were convalescent from erythema migrans and 19 of the 35 patients (54%) with neuroborreliosis had weak IgG responses to purified MgaID, and a smaller percentage of patients had early responses to synthetic ACG. However, almost all of 75 patients with Lyme arthritis, a late disease manifestation, had strong IgG reactivity with both glycolipids. Thus, almost all patients with Lyme arthritis have strong IgG antibody responses to B. burgdorferi glycolipid antigens. (C) 2009 Elsevier Inc. All rights reserved.

ID CAPTURE
AB Objective: We compared IPX054, a bilayer tablet of immediate- and extended-release carbidop-/levodopa (CD/LD) given twice daily to standard CD/LD given 4 times daily in patients with stable Parkinson disease (PD).
Methods: Twelve PD patients with no or mild fluctuations oil CD/LD 25/100 mg 4 times daily were randomized to a double-blind crossover comparison with IPX054 (50/200 mg) twice daily. At the end of each 2-week treatment, patients were video recorded while performing a modified Unified Parkinson's Disease Rating Scale motor examination and Rush Dyskinesia Rating Scale at 30-minute intervals over 8.5 hours. The primary Outcome measure was the number of videotape epochs rated as "ON" without troublesome dyskinesia by a blinded observer (Wilcoxon signed rank tests).
Results: The 9 men and 3 women had a mean age of 69 years and mean PD duration of 6 years. IPX054 and CD/LD showed no significant differences in the primary outcome measure (mean number of video epochs rated as ON without troublesome dyskinesia; P = 0.14). The mean time to ON was improved with IPX054 (P = 0.014), and the mean modified Unified Parkinson's Disease Rating Scale scores slightly favored IPX054 (14.4 vs 16.9; P = 0.052.). Mean Rush Dyskinesia Rating Scale scores were not significantly different between IPX054 and CD/LD (0.45 vs 0.69; P = 0.25). No patient developed troublesome dyskinesias.
Conclusions: in stable PD patients, no difference was detected between twice-daily treatment with IPX054 and CD/LD given 4 times daily In this group, substitution with IPX054 reduced closing frequency while maintaining CD/LD efficacy. In clinical practice, this case of administration may offer improved treatment compliance.

AB Although high-flexion TKA designs aim to safely accommodate deep flexion, it is unknown how often patients use deep flexion outside the laboratory. We used a validated smart-activity monitor to document the prevalence of knee flexion greater than 90 degrees in 20 consecutive patients (21 knees) who had high-flexion TKAs, at a minimum of 2 years' followup. Patients wore the device continuously for a mean of 35.7 +/- 0.5 hours. The 21 knees flexed more than 90 for an average of 10 +/- 3.8 minutes (0.5%). Activities performed with flexion greater than 90 degrees were, on average, 70% in single-limb stance, 12% moving from sitting to standing, 8% walking, 7% moving from standing to reclining, 2% stepping, 0.9% moving from lying to standing, and 0.1% running. Eight knees flexed greater than 120 for an average of 2.2 minutes (range, 0.2-15 minutes), or 0.1% of the testing time. Activities performed with flexion greater than 120 degrees were, on average, 90% in single-limb stance, 6% moving from sitting to standing, 3% walking, 0.6% moving from standing to reclining, 0.3% stepping, and 0.1% moving from lying to standing. Peak flexion used at any time during testing was, on average, 84% +/- 11% of maximum postoperative flexion (125 degrees +/- 12 degrees). These patients rarely used deep flexion.

AB Background. Active commuting to school provides regular exercise, which can improve asthma symptoms. Little is known about how children with asthma travel to school. Objective. To identify travel patterns and parental perceptions surrounding mode of travel to school among children with asthma. Methods. Cross-sectional study of 176 children with asthma aged 5 to 15 years. Parents completed questionnaires assessing mode of travel to school, physical activity, asthma control, physician counseling, and factors influencing parental decisions. Data analysis included descriptive and bivariate statistics. Results. Few (16%) children with asthma actively commute to school. Active travelers lived closer to school, and "distance" was the most frequently reported factor influencing a parent's decision regarding travel mode to school. Parents reported few concerns about pollution and little physician counseling on active travel. Conclusion. Few children with asthma actively travel to school. Asthma-specific concerns do not appear to guide parental decisions on travel mode to school.

AB The aim of the study was to evaluate the expressions of adhesion molecules (AM) on peripheral blood mononuclear cells (PBMNC) from systemic sclerosis (SSc) patients. Thirty-one SSc patients (ACR) and 20 normal subjects were selected for the study. PBMNC were analyzed for LFA-1 alpha, LFA-1 beta, ICAM-3, ICAM-1, and l-selectin expressions. ICAM-3 expression was decreased while ICAM-1 was increased on SSc PBMNC, compared to controls (p = 0.04 and 0.003, respectively). A positive association was found between LFA-1 alpha (r = 0.37, p = 0.03), LFA-1 beta (r = 0.38, p = 0.002), ICAM-3 (r = 0.42, p = 0.01), and l-selectin (r = 0.38, p = 0.03) expressions and greater number of immunosuppressive drugs taken by SSc patients. Also, anti-centromeric positive SSc patients had lower expressions of LFA-1 alpha, LFA-1 beta, ICAM-3, and l-selectin. Lower expression of ICAM-3 and higher expression of ICAM-1 suggest that AMs may be involved in the pathogenesis of scleroderma.

AB Purpose: To describe changes in demographics and pathogens for fungal keratitis cases diagnosed at the Massachusetts Eye and Ear Infirmary.
Methods: Patient demographics, clinical and laboratory findings, treatment and outcomes of 46 cases of culture-proven fungal keratitis diagnosed from January 2004 through November 2007 were compared with 23 cases of fungal keratitis previously collected over a similar period from January 1999 through November 2002.
Results: During 2004-2007, the rate of fungal keratitis was 1.0 cases per month, an increase from the baseline rate of 0.5 cases per month during 1999-2002. The proportion of cases caused by filamentous fungi increased from 30% (1999-2002) to 65% (2004-2007) (P=0.01). Soft contact lens wear accounted for 41% of fungal keratitis cases in 2004-2007, as compared with 17% in 1999-2002. The majority of patients (70%) received oral antifungal treatment in addition to topical amphotericin B and natamycin. Seventeen patients (40%) required therapeutic keratoplasty. Patients with a history of conical transplant had the highest rate of therapeutic keratoplasties (67%) and had the poorest visual outcome (40% counting fingers or less). In the contact lens group, 94% of patients maintained vision of at least 20/40 and only 12% required surgery to control the infection.
Conclusions: There has been an increase in fungal keratitis in the Boston area and a change in the causative pathogens and risk factors for infection. Filamentous fungi now account for the majority of fungal keratitis cases, whereas yeasts were the predominant pathogen in the past. Soft contact lens wear is currently the most common risk factor for development of fungal keratitis.

AB Objective: Regionalization has been proposed as a method to improve outcomes for patients with critical illness. We sought to determine intensivist physician attitudes and potential barriers to the regionalization of adult critical care.
Design: Mail survey.
Setting. United States.
Subjects: Actively practicing physicians specializing in adult critical care, emergency medicine, or internal medicine listed in the 2008 American Medical Association Physician Masterfile (n = 1200).
Interventions: None.
Measurements and Main Results: There were 569 eligible respondents (effective response rate = 53.0%). Respondents were similar to nonrespondents. Fifty-nine percent of respondents thought their hospital would mainly receive patients under a regionalized system, and 30% thought their hospital would mainly send patients. Opinions were split about whether regionalization would improve overall patient survival (52% agreed) and healthcare efficiency (66% agreed). Specialists in anesthesiology and surgery-critical care, academic physicians, and physicians who perceived that they would mainly receive patients were more likely to believe that regionalization would improve outcomes and efficiency (p < 0.001). The most commonly endorsed barriers to regionalization were personal strain on patient's families (66% agreed), current lack of a strong central authority (64% agreed), and the potential to overwhelm capacity at large hospitals (55% agreed). Commonly endorsed strategies to implement regionalization included using objective criteria to determine eligibility for transfer (87% agreed), developing common information technology platforms across hospitals (86% agreed), and demonstrating in a clinical trial that regionalization is beneficial (81% agreed).
Conclusions: Intensivist physicians have mixed opinions about regionalization, with little consensus about whether regionalization will improve outcomes. Most felt that regionalization will improve patient outcomes, but many expressed concerns about unintended adverse consequences. Respondents identified several barriers and potential implementation strategies that can help policymakers design a regionalized system of critical care in the United States.

AB Objective: Neutrophilic inflammation plays a key role in the pathogenesis of acute respiratory distress syndrome (ARDS) and acute lung injury (ALI). Positron emission tomography (PET) with [(18)F]-fluoro-2-deoxy-D-glucose ((18)FDG) can be used to image cellular metabolism that, during lung inflammatory processes, likely reflects neutrophils activity. The aim of this study was to assess the magnitude and regional distribution of inflammatory metabolic activity in the lungs of patients with ALI/ARDS by PET with (18)FDG.
Design: Prospective clinical investigation.
Patients. Ten patients with ALI/ARDS; four spontaneously breathing and two mechanically ventilated subjects, without known lung disease, served as controls.
Interventions. In each individual we performed an (18)FDG PET/computed tomography of the thorax.
Measurements and Main Results. (18)FDG cellular influx rate constant (K(i)) was computed for the imaged lung field and for regions of interest, grouping voxels with similar density. In all patients with ALI/ARDS, K(i) was higher than in controls, also after accounting for the increased lung density. K(i) values differed greatly among patients, but in all patients K(i) of the normally aerated regions was much higher (2- to 24-fold) than in controls. Whereas in some patients the highest K(i) values corresponded to regions with the lowest aeration, in others these regions had lower K(i) than normally and mildly hypoaerated regions.
Conclusion: In patents with ALI/ARDS, undergoing mechanical ventilation since days, the metabolic activity of the lungs is markedly increased across the entire lung density spectrum. The intensity of this activation and its regional distribution, however, vary widely within and between patents. (Crit Care Med 2009; 37:2216-2222)

AB Exsanguinating hemorrhage is a common clinical feature of multisystem trauma that results in death or severe disability. Cardiovascular collapse resulting from hemorrhage is unresponsive to conventional methods of cardiopulmonary resuscitation. Even when bleeding is controlled rapidly, adequate circulation cannot be restored in time to avoid neurologic consequences that appear after only 5 mins of cerebral ischemia and hypoperfusion. Reperfusion adds further insult to injury. A novel solution to this problem would be to institute a therapy that makes cells and organs more resistant to ischemic injury, thereby extending the time they can tolerate such an insult. Hypothermia can attenuate some effects of ischemia and reperfusion. Accumulating preclinical data demonstrate that hypothermia can be induced safely and rapidly to achieve emergency preservation for resuscitation during lethal hemorrhage. Hypothermia may be an effective therapeutic approach for otherwise lethal traumatic hemorrhage, and a clinical trial to determine its utility is warranted. (Crit Care Med 2009; 37[Suppl.]:S265-S272)

AB Purpose of review
The review assesses the evidence for the benefit of lower blood pressure (BP) targets in hypertension management.
Recent findings
The current consensus target for the treatment of hypertension is a BP of below 140/90 mmHg for all patients, and a BP of below 130/80 mmHg for those with diabetes or chronic kidney disease. Recently added to the list of conditions warranting the lower BP target are coronary artery disease and coronary artery disease equivalents (stroke, carotid disease, aortic aneurysm, and peripheral vascular disease), as well as those individuals with a Framingham Risk Score of at least 10%. One theoretical issue with lower BP targets may be the existence of a J-shaped curve of BP versus cardiovascular event rate, implying a greater risk, especially of myocardial ischemia, of lowering diastolic BP, which is also the filling pressure of the coronary arteries, below the lower limit of coronary autoregulation. The evidence that this is not a compelling concern is provided by animal studies, clinical trials with both surrogate and hard endpoints, and epidemiologic data.
Summary
There is at present no proof that more aggressive treatment is harmful and much indirect evidence that it may be beneficial, although the clinical trials that specifically address this question are still in progress.

MECHANISMS
AB Purpose of review
There is currently a major debate on the mechanisms of albuminuria, and this review appraises recent studies in this area.
Recent findings
The traditional view of albuminuria is that it is the result of damage to an essentially impermeable glomerular barrier. However, over the years, critical evidence for this traditional model has been shown to be flawed. An alternative explanation has evolved in which the glomerular filter governs albumin permeability by size selectivity alone. This means that the filter offers a significant barrier to albumin, but it is imperfect - the barrier leaks albumin. The virtue of this leakage is that it endows the filter an in-built anticlogging mechanism. The filtered albumin, if not rescued, would be excreted at nephrotic levels in the urine. There is evidence that proximal tubular cells participate in retrieving most of this filtered albumin to return it back to the blood supply intact. A small amount of the filtered albumin is not retrieved but directed toward lysosomal degradation, and the peptide products are exocytosed into the tubular lumen and excreted.
Summary
In acquired and chemically induced kidney disease, albuminuria is the result of dysfunction in proximal tubular cell processing of albumin rather than alterations in glomerular permeability.

AB Purpose of review
A growing number of veterans in the Veterans Health Administration are coinfected with HIV and hepatitis C virus. This review covers timely research relative to comorbid conditions that are common in this population including psychiatric diagnoses, substance use disorders and neurocognitive problems.
Recent findings
Current literature on the psychiatric, substance use disorders and cognitive problems of the coinfected population show that not only are rates of morbidity higher in the coinfected population but that this affects antiviral treatments as well. There is new evidence that brain injuries and infiltration of the virus into the central nervous system may be responsible for cognitive dysfunction. Cotesting, particularly in hepatitis C infected individuals, is not done routinely despite shared risk factors.
Summary
With this understanding of the comorbidities of the coinfected population, integrated healthcare models involving mental health, internal medicine, substance abuse treatment and internal medicine are crucial to work with these medically and psychologically complex patients.

AB Context: Outcomes of antidepressant medication treatment for major depressive disorder include remission, response, and nonresponse. But nonresponse can include depression that worsened over the course of treatment, an outcome that has received scant attention. Objective: To describe baseline sociodemographic, clinical, and treatment characteristics associated with worsened depression during a trial of citalopram. Design, participants, and settings: Open-label clinical trial of 2,876 adult outpatients seen in 18 primary and 23 psychiatric-care settings. Intervention: Citalopram was delivered using measurement-based care and flexible dosing with the aim of achieving symptom remission. Symptom and side effect ratings were obtained at each treatment visit. Main outcome measures: Worsened depression was defined as an exit score ! 3 points above the pretreatment (baseline) score on the 16-item QIDS-SR. Baseline sociodemographic, clinical, and treatment characteristics were examined for association with worsened depression. Results: Of 2,864 outpatients who returned for >= 2 post baseline visits, 150 (5.2%) had worsened depression at study exit. Baseline characteristics independently associated with increased worsened depression included African-American race (OR = 2.02), having less than a college education (OR = 2.36), posttraumatic stress disorder (OR = 1.78), drug abuse (OR = 1.97), hypochondriasis (OR = 2.74). Participants with worsened depression spent less time in treatment; had fewer treatment visits; exited the study sooner; bad more frequent, intense, and burdensome adverse effects; and were more intolerant of medication. Conclusions: The presence of certain baseline characteristics indicated a greater likelibood of worsened depression during antidepressant treatment. Patients with these characteristics should be monitored closely during treatment and may be candidates for more aggressive treatment. Depression and Anxiety 26:612-621, 2009.

AB Background: Attrition, or dropping out of treatment, remains a major issue in the care of depressed outpatients. Whether different factors are associated with attrition for different socioeconomic groups is not known. This report assessed whether attrition rates and predictors of attrition differed among depressed outpatients with different income levels. Methods: Outpatients with non-psychotic major depressive disorder treated for up to 14 weeks with citalopram in the first step of the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study were divided by household incomes of <$20,000, $20,000-<$40,000, and >=$40,000. Attrition rates and sociodemographic and clinical correlates of attrition were identified for each group. Results: Regardless of income level, remission rates were lower for participants who dropped out of treatment. Attrition rates increased as income decreased. For all income levels, younger age was independently associated with attrition. For the lowest income level, less education, better mental health functioning, being oil public insurance, and having more concurrent Axis I conditions were associated with a greater likelihood of attrition. For the middle income group, less education, better mental health functioning, being Black or of another non-White race, and treatment in a psychiatric versus primary-care setting predicted greater attrition. For the highest income group, being Hispanic, having a family history of drug abuse, and melancholic features predicted attrition. Atypical symptom features (middle income group) and recurrent depression (highest income group) were associated with retention. Conclusions: Efforts to retain patients in antidepressant treatment should focus especially on less educated patients with lower household incomes and younger patients.

AB BACKGROUND Patient satisfaction is an important aspect of patient-centered care but has not been systematically studied after treatment of nonmelanoma skin cancer (NMSC), the most prevalent cancer.
OBJECTIVE To compare patient satisfaction after treatment for NMSC and to determine factors associated with better satisfaction.
METHODS We prospectively measured patient, tumor, and care characteristics in 834 consecutive patients at two centers before and after destruction, excision, and Mohs surgery. We evaluated factors associated with short-term and long-term satisfaction.
RESULTS In all treatment groups, patients were more satisfied with the interpersonal manners of the staff, communication, and financial aspects of their care than with the technical quality, time with the clinician, and accessibility of their care (p<.05). Short-term satisfaction did not differ across treatment groups. In multivariable regression models adjusting for patient, tumor, and care characteristics, higher long-term satisfaction was independently associated with younger age, better pretreatment mental health and skin-related quality of life, and treatment with Mohs surgery (p<.05).
CONCLUSIONS Long-term patient satisfaction after treatment of NMSC is related to pretreatment patient characteristics (mental health, skin-related quality of life) and treatment type (Mohs) but not tumor characteristics. These results can guide informed decision-making for treatment of NMSC.

TI Sensitivity of Lipid Metabolism and Insulin Signaling to Genetic
Alterations in Hepatic Peroxisome Proliferator-Activated Receptor-gamma

AB OBJECTIVE-The peroxisome proliferator-activated receptor-gamma coactivator (PGC)-1 family of transcriptional coactivators controls hepatic function by modulating the expression of key metabolic enzymes. Hepatic gain of function and complete genetic ablation of PGC-1 alpha show that this coactivator is important for activating the programs of gluconeogenesis, fatty acid oxidation, oxidative phosphorylation, and lipid secretion during times of nutrient deprivation. However, how moderate changes in PGC-1 alpha activity affect metabolism and energy homeostasis has yet to be determined.
RESEARCH DESIGN AND METHODS-To identify key metabolic pathways that may be physiologically relevant in the context of reduced hepatic PGC-1 alpha levels, we used the Cre/Lox system to create mice heterozygous for PGC-1 alpha specifically within the liver (LH mice).
RESULTS-These mice showed fasting hepatic steatosis and diminished ketogenesis associated with decreased expression of genes involved in mitochondrial beta-oxidation. LH mice also exhibited high circulating levels of triglyceride that correlated with increased expression of genes involved in triglyceride-rich lipoprotein assembly. Concomitant with defects in lipid metabolism, hepatic insulin resistance was observed both in LH mice fed a high-fat diet as well as in primary hepatocytes.
CONCLUSIONS-These data highlight both the dose-dependent and long-term effects of reducing hepatic PGC-1 alpha levels, underlining the importance of tightly regulated PGC-1 alpha expression in the maintenance of lipid homeostasis and glucose metabolism. Diabetes 58:1499-1508, 2009

AB OBJECTIVE-Linkage of the chromosome 1q21-25 region to type 2 diabetes has been demonstrated in multiple ethnic groups. We performed common variant fine-mapping across a 23-Mb interval in a multiethnic sample to search for variants responsible for this linkage signal.
RESEARCH DESIGN AND METHODS-In all, 5,290 single nucleotide polymorphisms (SNPs) were successfully genotyped in 3,179 type 2 diabetes case and control subjects from eight populations with evidence of 1q linkage. Samples were ascertained using strategies designed to enhance power to detect variants causal for 1q linkage. After imputation, we estimate similar to 80% coverage of common variation across the region (r(2) > 0.8, Europeans). Association signals of interest were evaluated through in silico replication and de novo genotyping in similar to 8,500 case subjects and 12,400 control subjects.
RESULTS-Association mapping of the 23-Mb region identified two strong signals, both of which were restricted to the subset of European-descent samples. The first mapped to the NOS1AP (CAPON) gene region (lead SNP: rs7538490, odds ratio 1.38 [95% CI 1.21-1.571, P = 1.4 x 10(-6), in 999 case subjects and 1,190 control subjects); the second mapped within an extensive region of linkage disequilibrium that includes the ASH1L and PKLR genes (lead SNP: rs11264371, odds ratio 1.48 [1.18-1.761, P = 1.0 x 10(-5), under a dominant model). However, there was no evidence for association at either signal on replication, and, across all data (>24,000 subjects), there was no indication that these variants were causally related to type 2 diabetes status.
CONCLUSIONS-Detailed fine-mapping of the 23-Mb region of replicated linkage has failed to identify common variant signals contributing to the observed signal. Future studies should focus on identification of causal alleles of lower frequency and higher penetrance. Diabetes 58:1704-1709, 2009

DT Article
AB Purpose
The practice analysis described in this report was conducted by the National Certification Board for Diabetes Educators (NCBDE) to (1) provide a basis for documenting the continuing validity of the Certification Examination for Diabetes Educators, (2) define new areas that should be assessed in future certification examinations, and (3) ensure that the content of certification examinations is related to practice.
Methods
The study involved developing a diabetes educator job task list and survey, distributing 4103 surveys, and analyzing survey responses from a multidisciplinary and geographically representative sample of certified diabetes educators.
Results
Eight hundred thirty-six surveys were suitable for analysis, with relevant demographic subgroups adequately represented. Based on survey data, an examination matrix and detailed content outline was constructed that will be used by NCBDE to assemble future test forms.
Conclusions
Certification examination specifications were developed directly related to the important activities that diabetes educators perform. Future forms of the certification examination will continue to be matched to job-related, criterion-referenced test specifications and will have strong evidence of content validity. Future forms of the exam will contain 200 items at specified cognitive levels with a representative sampling of tasks within 3 core areas from the detailed content outline.

AB Embryonic stem cells (ESCs) have been shown to be capable of differentiating into pancreatic progenitors and insulin-producing cells in vitro. However, before ESC derivatives can be used in clinical settings, efficient selective differentiation needs to be achieved. Essential to improving ESC differentiation to islet endocrine cells is an understanding of the influences of extrinsic signals and transcription factors on cell specification. Herein, we investigate the influence of serum-supplemented growth conditions on the differentiation of murine ESCs to endocrine lineages in the context of over-expression of two pancreatic transcription factors, Pdx1 and Ngn3.
To study the effect of different serum formulations and concentrations on the ability of murine ESCs to differentiate into endocrine cells in vitro, cells were grown into embryoid bodies and then differentiated in various serum replacement (SR), fetal calf serum (FCS) and serum-free conditions. Using immunohistochemistry and quantitative real-time RT-PCR (QPCR), we found that, of the conditions tested, 1% SR differentiation medium resulted in the highest levels of insulin-1 mRNA and significantly increased the total number of insulin-expressing cells. Applying this knowledge to cell lines in which Pdx1 or Ngn3 transgene expression could be induced by exposure to doxycycline we differentiated TetPDX1 and TetNgn3 ESCs under conditions of either 10% FCS or 1% SR medium. In the presence of 10% serum, induced expression of either Pdx1 or Ngn3 in differentiating ESCs resulted in modest increases in hormone transcripts and cell counts. However, changing the serum formulation from 10% FCS to 1% SR significantly enhanced the number of insulin+/C-peptide+ cells in parallel with increased insulin-1 transcript levels in both inducible cell lines. In summary, these data demonstrate that induced expression of key pancreatic transcription factors in combination with low serum/SR concentrations increases endocrine cell differentiation from murine ESCs.

AB Introduction Complications following pancreaticoduodenectomy (PD) often necessitate nutritional support. This study analyzes the utilization of parenteral nutrition (TPN) during the surgical admission as evidence for or against routine jejunostomy placement. Methods The California Cancer Registry (1994-2003) was linked to the California Inpatient File; PD for adenocarcinoma was performed in 1,873 patients. TPN use and enterostomy tube placement were determined and preoperative characteristics predictive of TPN use during the surgical admission were identified. Results Fourteen percent of patients received TPN, 23% underwent enterostomy tube placement, and 63% received no supplemental nutritional support. TPN was associated with longer hospital stay (18 vs. 13 days, P < 0.0001). The Charlson Comorbidity Index (CCI) a parts per thousand yen 3 had nearly two-fold greater odds of receiving TPN (odds ratio [OR] = 1.85, P < 0.005). Conclusion Approximately 1 in 6 patients undergoing PD received TPN, which was associated with prolonged hospital stay. CCI a parts per thousand yen 3 was associated with increased odds of TPN utilization. Selected jejunostomy placement in patients with high CCI is worthy of consideration.

AB Background: Cocaine dependence is a major public health problem for which there is no FDA-approved pharmacological treatment. Baclofen is a GABA(B) receptor agonist that in preclinical and early pilot clinical trials has shown promise for the treatment of cocaine dependence. The purpose of this multi-site, double-blind study, was to compare the safety and efficacy of baclofen (60 mg/day) vs placebo in an 8-week treatment of individuals with severe cocaine dependence. The primary Outcome measure was subjects' self-reported cocaine use substantiated by urine benzoylecgonine (BE). Analysis of the data did not show a significant difference between the groups treated with baclofen and placebo. The current results do not support a role for 60 mg baclofen in treating cocaine dependence in the population studied. The contrast of this result to earlier, preclinical and human pilot data with baclofen may reflect the trial's focus on severe cocaine-dependent users, and/or the need for a higher baclofen dose. Baclofen's potential as a relapse prevention agent was not tested by the current design, but may be a useful target for future studies. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

AB This report describes a microfluidic solid-phase chemical gradient-mediated melting curve analysis method for SNP analysis. The method is based on allele-specific denaturation to discriminate mismatched (MM) from perfectly matched (PM) DNA duplexes upon exposure to linear chemical gradient. PM and MM DNA duplexes conjugated on beads are captured in a microfluidic gradient generator device designed with dams, keeping the beads trapped perpendicular to a gradient generating channel. Two denaturants, formamide and urea, were tested for their ability to destabilize the DNA duplex by competing with Watson-Crick pairing. Upon exposure to the chemical gradient, rapid denaturing profile was monitored in real time using fluorescence microscopy. The results show that the two duplexes exhibit different kinetics of denaturation profiles, enabling discrimination of MM from PM DNA duplexes to score SNP.

AB Understanding the biological pathways critical for common neurofibromatosis type 1 (NF1) peripheral nerve tumours is essential, as there is a lack of tumour biomarkers, prognostic factors and therapeutics. We used gene expression profiling to define transcriptional changes between primary normal Schwann cells (n - 10), NF1-derived primary benign neurofibroma Schwann cells (NFSCs) (n = 22), malignant peripheral nerve sheath tumour (MPNST) cell lines (n = 13), benign neurofibromas (NF) (n = 26) and MPNST (n = 6). Dermal and plexiform NFs were indistinguishable. A prominent theme in the analysis was aberrant differentiation. NFs repressed gene programs normally active in Schwann cell precursors and immature Schwann cells. MPNST signatures strongly differed; genes up-regulated in sarcomas were significantly enriched for genes activated in neural crest cells. We validated the differential expression of 82 genes including the neural crest transcription factor SOX9 and SOX9 predicted targets. SOX9 immunoreactivity was robust in NF and MPSNT tissue sections and targeting SOX9 - strongly expressed in NF1-related tumours - caused MPNST cell death. SOX9 is a biomarker of NF and MPNST, and possibly a therapeutic target in NF1.

AB Trimethylation of lysine 9 in histone H3 (H3K9me3) enrichment is a characteristic of pericentric heterochromatin. The hypothesis of a stepwise mechanism to establish and maintain this mark during DNA replication suggests that newly synthesized histone H3 goes through an intermediate methylation state to become a substrate for the histone methyltransferase Suppressor of variegation 39 (Suv39H1/H2). How this intermediate methylation state is achieved and how it is targeted to the correct place at the right time is not yet known. Here, we show that the histone H3K9 methyltransferase SetDB1 associates with the specific heterochromatin protein 1 alpha (HP1 alpha)-chromatin assembly factor 1 (CAF1) chaperone complex. This complex monomethylates K9 on non-nucleosomal histone H3. Therefore, the heterochromatic HP1 alpha-CAF1-SetDB1 complex probably provides H3K9me1 for subsequent trimethylation by Suv39H1/H2 in pericentric regions. The connection of CAF1 with DNA replication, HP1 alpha with heterochromatin formation and SetDB1 for H3K9me1 suggests a highly coordinated mechanism to ensure the propagation of H3K9me3 in pericentric heterochromatin during DNA replication.

AB P>Purpose:
Kv4.2 subunits contribute to the pore-forming region of channels that express a transient, A-type K(+) current (A-current) in hippocampal CA1 pyramidal cell dendrites. Here, the A-current plays an important role in signal processing and synaptic integration. Kv4.2 knockout mice show a near elimination of the A-current in area CA1 dendrites, producing increased excitability in this region. In these studies, we evaluated young adult Kv4.2 knockout mice for spontaneous seizures and the response to convulsant stimulation in the whole animal in vivo and in hippocampal slices in vitro.
Methods:
Electroencephalogram electrode-implanted Kv4.2 knockout and wild-type mice were observed for spontaneous behavioral and electrographic seizures. The latency to seizure and status epilepticus onset in Kv4.2 knockout and wild-type mice was assessed following intraperitoneal injection of kainate. Extracellular field potential recordings were performed in hippocampal slices from Kv4.2 knockout and wild-type mice following the bath application of bicuculline.
Results:
No spontaneous behavioral or electrographic seizures were observed in Kv4.2 knockout mice. Following kainate, Kv4.2 knockout mice demonstrated a decreased seizure and status epilepticus latency as well as increased mortality compared to wild-type littermates. The background strain modified the seizure susceptibility phenotype in Kv4.2 knockout mice. In response to bicuculline, slices from Kv4.2 knockout mice exhibited an increase in epileptiform bursting in area CA1 as compared to wild-type littermates.
Discussion:
These studies show that loss of Kv4.2 channels is associated with enhanced susceptibility to convulsant stimulation, supporting the concept that Kv4.2 deficiency may contribute to aberrant network excitability and regulate seizure threshold.

AB We report a novel technology for the rapid healing of large osseous and chondral defects, based upon the genetic modification of autologous skeletal muscle and fat grafts. These tissues were selected because they not only possess mesenchymal progenitor cells and scaffolding properties, but also can be biopsied, genetically modified and returned to the patient in a single operative session. First generation adenovirus vector carrying cDNA encoding human bone morphogenetic protein-2 (Ad. BMP-2) was used for gene transfer to biopsies of muscle and fat. To assess bone healing, the genetically modified ("gene activated") tissues were implanted into 5mm-long critical size, mid-diaphyseal, stabilized defects in the femora of Fischer rats. Unlike control defects, those receiving gene-activated muscle underwent rapid healing, with evidence of radiologic bridging as early as 10 days after implantation and restoration of full mechanical strength by 8 weeks. Histologic analysis suggests that the grafts rapidly differentiated into cartilage, followed by efficient endochondral ossification. Fluorescence in situ hybridization detection of Y-chromosomes following the transfer of male donor muscle into female rats demonstrated that at least some of the osteoblasts of the healed bone were derived from donor muscle. Gene activated fat also healed critical sized defects, but less quickly than muscle and with more variability. Anti-adenovirus antibodies were not detected. Pilot studies in a rabbit osteochondral defect model demonstrated the promise of this technology for healing cartilage defects. Further development of these methods should provide ways to heal bone and cartilage more expeditiously, and at lower cost, than is presently possible.

AB Cardiac biomarkers are routinely elevated after uncomplicated cardiac surgery to levels considered diagnostic of myocardial infarction in ambulatory populations. We investigated the diagnostic power of electrocardiogram (ECG) and cardiac biomarker criteria to predict clinically relevant myocardial injury using benchmarks of mortality and increased hospital length of stay (HLOS) in patients undergoing coronary artery bypass graft (CABG) surgery.
Perioperative ECGs, creatinine kinase MB fraction, and cardiac troponin I (cTnI) were assessed in 545 primary CABG patients. None of the ECG criteria for myocardial injury predicted mortality or HLOS. However, post-operative day (POD) 1 cTnI levels independently predicted 5-year mortality (hazard ratio = 1.42; 95% CI 1.14-1.76 for each 10 mu g/L increase; P = 0.009), while adjusting for baseline demographic characteristics and perioperative risk factors. Moreover, cTnI was the only biomarker that significantly improved the prediction of 5-year mortality estimated by the logistic Euroscore (P = 0.02). Furthermore, the predictive value of cTnI for 5-year mortality was replicated in a separately collected cohort of 1031 CABG patients using cardiac troponin T.
Electrocardiogram diagnosis of post-operative myocardial injury after CABG does not independently predict an increased risk of 5-year mortality or HLOS. Conversely, cTnI is independently associated with an increased risk of mortality and prolonged HLOS.

AB To examine the extent of platelet inhibition by prasugrel vs. clopidogrel in a TRITON-TIMI 38 substudy.
TRITON-TIMI 38 randomized acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) to prasugrel or standard dose clopidogrel. Selected sites prospectively enrolled TRITON-TIMI 38 patients to evaluate adenosine diphosphate (ADP)-attenuated phosphorylation of platelet vasodilator-stimulated phosphoprotein (VASP) (n = 125 patients) and, in a subset (n = 31 patients), ADP-stimulated platelet aggregation. VASP platelet reactivity index (PRI) was lower in prasugrel-treated patients than in clopidogrel-treated patients at 1-2 h post-PCI (>= 1 h after loading dose) (P < 0.001) and at 30 days (P < 0.001). Maximal platelet aggregation to 20 mu M ADP was lower in prasugrel-treated patients than in clopidogrel-treated patients at 1-2 h (P = 0.004) and 30 days (P = 0.03). Results were similar with 5 mu M ADP. Thienopyridine hyporesponsiveness, prespecified as VASP PRI > 50%, was more frequent in clopidogrel-treated patients than in prasugrel-treated patients at 1-2 h (P < 0.001) and 30 days (P = 0.03).
The TRITON-TIMI 38 platelet substudy shows that prasugrel results in greater inhibition of ADP-mediated platelet function in ACS patients than clopidogrel, supporting the hypothesis that greater platelet inhibition leads to a lower incidence of ischaemic events and more bleeding both early and late following PCI.

AB Aims: To assess the antitumour activity, safety, pharmacokinetics and pharmacodynamics of continuous daily sunitinib dosing in patients with imatinib-resistant/intolerant gastrointestinal stromal tumour (GIST) and to assess morning dosing versus evening dosing.
Patients and methods: In this open-label phase II study, patients were randomised to receive morning or evening dosing of sunitinib 37.5 mg/day. The primary end-point was clinical benefit rate (CBR; percent complete responses + partial responses [PRs] + stable disease [SD] >= 24 weeks). Secondary end-points included progression-free survival (PFS), overall survival (OS), safety, pharmacokinetic parameters and plasma biomarker levels.
Results: Sixty of 61 planned patients received treatment (30 per dosing group); 26 completed the study. overall, the CBR was 53% (95% exact CI, 40-66): eight patients (13%) achieved objective PRs; 24 (40%) achieved SD >= 24 weeks. Median PFS was 34 weeks (95% CI, 24-49); median OS was 107 weeks (95% CI, 72 - not yet calculable). Most adverse events (AEs) were of grade 1 or 2 in severity, and were manageable through dose modification or standard interventions. No new AEs were apparent compared with the approved intermittent dosing schedule. Antitumour activity and safety were generally similar with morning and evening dosing. Continuous daily sunitinib dosing achieved and sustained effective drug concentrations without additional accumulation across cycles. Decreases from baseline in plasma levels of soluble KIT after 20 and 24 weeks of dosing correlated with longer OS.
Conclusion: For patients with imatinib-resistant/intolerant GIST, continuous daily sunitinib dosing appears to be an active alternative dosing strategy with acceptable safety. (c) 2009 Published by Elsevier Ltd.

AB Nuclear beta-catenin and CD133 are linked with two hallmarks of colon cancer, wingless-type mouse mammary tumour virus integration site (WNT)-pathway dysregulation and colon cancer stem cells (Co-CSCs), respectively Both molecules may be related, as Co-CSCs were proposed to require activated WNT-signalling and as CD133 was postulated as a WNT/beta-catenin target gene. Herein, we investigated the expression of these markers on serial sections of 162 stage IIA colonic adenocarcinomas. We found that the expression of these molecules is statistically independent and that they mark distinct but overlapping subpopulations of the tumour cells. Moreover, we show that their combined evaluation can identify colon cancer cases with vastly reduced survival (hazard ratio (HR) 13.4, 95% confidence interval (CI): 4.7-38.2) and a high risk of tumour progression (HR 6.8, 95%CI: 3.1-15.0). In conclusion, the independence of these markers may on the one hand have implications for their presumed value to identify Co-CSCs; on the other hand it allows their combined analysis to become a powerful tool to identify high risk cases of stage IIA colon cancer.

AB Aims Two-dimensional echocardiographic (2DE) assessment of right ventricular ( RV) function is difficult, often resulting in inconsistent RV evaluation. Real-time three-dimensional echocardiography (RT3DE) allows the RV to be viewed in multiple planes, which can potentially improve RV assessment and limit interobserver variability when compared with 2DE.
Methods and results Twenty-five patients underwent 2DE and RT3DE. Views of 2DE ( RV inflow, RV short axis, and apical four-chamber) were compared with RT3DE views by four readers. RT3DE data sets were sliced from anterior-posterior ( apical view) and from base to apex ( short axis) to obtain six standardized planes. Readers recorded the RV ejection fraction (RVEF) from 2DE and RT3DE images. RVEF recorded by RT3DE (RVEF(3D)) and 2D (RVEF(2D)) were compared with RVEF by disc summation (RVEF(DS)), which was used as a reference. Interobserver variability among readers of RVEF3D and RVEF2D was then compared. Overall, mean RVEF(DS), RVEF(3D), and RVEF(2D) were 37 +/- 11%, 38 +/- 10%, 41 +/- 10%, respectively. The mean difference of RVEF(3D) - RVEF(DS) was significantly less than RVEF(2D)-RVEF(DS) (3.7 +/- 4% vs. 7.1 +/- 5%, P = 0.0066, F-test). RVEF(3D) correlated better with RVEF(DS) (r = 0.875 vs. r = 0.69, P = 0.028, t-test). RVEF(3D) was associated with a 39% decrease in interobserver variability when compared with RVEF(2D) [standard deviation of mean difference: 3.7 vs. 5.1, (RT3DE vs. 2DE), P = 0.018, t-test].
Conclusions RT3DE provides improved accuracy of RV function assessment and decreases interobserver variability when compared with 2D views.

AB Terminology and principles of combining antipsychotics with a second medication. The term "combination" includes virtually all the ways in which one medication may be added to another. The other commonly used terms are "augmentation" which implies an additive effect from adding a second medicine to that obtained from prescribing a first, an "add on" which implies adding on to existing, possibly effective treatment which, for one reason or another, cannot or should not be stopped. The issues that arise in all potential indications are: a) how long it is reasonable to wait to prove insufficiency of response to monotherapy; b) by what criteria that response should be defined; c) how optimal is the dose of the first monotherapy and, therefore, how confident can one be that its tack of effect is due to a truly inadequate response?
Before one considers combination treatment, one or more of the following criteria should be met; a) monotherapy has been only partially effective on core symptoms; b) monotherapy has been effective on some concurrent symptoms but not others, for which a further medicine is believed to be required; c) a particular combination might be indicated de novo in some indications; d) The combination could improve tolerability because two compounds may be employed below their individual dose thresholds for side effects. Regulators have been concerned primarily with a and, in principle at least, c above. In clinical practice, the use of combination treatment reflects the often unsatisfactory outcome of treatment with single agents.
Antipsychotics in mania. There is good evidence that most antipsychotics tested show efficacy in acute mania when added to lithium or valproate for patients showing no or a partial response to lithium or valproate alone. Conventional 2-armed trial designs could benefit from a third antipsychotic monotherapy arm.
In the long term treatment of bipolar disorder, in patients responding acutely to the addition of quetiapine to lithium or valproate, this combination reduces the subsequent risk of relapse to depression, mania or mixed states compared to monotherapy with lithium or valproate. Comparable data is not available for combination with other antipsychotics.
Antipsychotics in major depression. Some atypical antipsychotics have been shown to induce remission when added to an antidepressant (usually a SSRI or SNRI) in unipolar patients in a major depressive episode unresponsive to the antidepressant monotherapy. Refractoriness is defined as at least 6 weeks without meeting an adequate pre-defined treatment response. Long term data is not yet available to support continuing efficacy.
Schizophrenia. There is only limited evidence to support the combination of two or more antipsychotics in schizophrenia. Any monotherapy should be given at the maximal tolerated dose and at least two antipsychotics of different action/tolerability and clozapine should be given as a monotherapy before a combination is considered.
The addition of a high potency D2/3 antagonist to a low potency antagonist like clozapine or quetiapine is the logical combination to treat positive symptoms, although further evidence from well conducted clinical trials is needed. Other mechanisms of action than D2/3 blockade, and hence other combinations might be more relevant for negative, cognitive or affective symptoms. Obsessive-compulsive disorder. SSRI monotherapy has moderate overall average benefit in OCD and can take as long as 3 months for benefit to be decided. Antipsychotic addition may be considered in OCD with tic disorder and in refractory OCD. For OCD with poor insight (OCD with "psychotic features"), treatment of choice should be medium to high dose of SSRI, and only in refractory cases, augmentation with antipsychotics might be considered. Augmentation with hatoperidol and risperidone was found to be effective (symptom reduction of more than 35%) for patients with tics. For refractory OCD, there is data suggesting a specific role for hatoperidol and risperidone as well, and some data with regard to potential therapeutic benefit with olanzapine and quetiapine.
Antipsychotics and adverse effects in severe mental illness. Cardio-metabotic risk in patients with severe mental illness and especially when treated with antipsychotic agents are now much better recognized and efforts to ensure improved physical health screening and prevention are becoming established.

AB Quantitative data on the range of in vivo vertebral motion is critical to enhance our understanding of spinal pathology and to improve the current surgical treatment methods for spinal diseases. Little data have been reported on the range of lumbar vertebral motion during functional body activities. In this study, we measured in vivo 6 degrees-of-freedom (DOF) vertebral motion during unrestricted weightbearing functional body activities using a combined MR and dual fluoroscopic imaging technique. Eight asymptomatic living subjects were recruited and underwent MRI scans in order to create 3D vertebral models from L2 to L5 for each subject. The lumbar spine was then imaged using two fluoroscopes while the subject performed primary flexion-extension, left-right bending, and left-right twisting. The range of vertebral motion during each activity was determined through a previously described imaging-model matching technique at L2-3, L3-4, and L4-5 levels. Our data revealed that the upper vertebrae had a higher range of flexion than the lower vertebrae during flexion-extension of the body (L2-3, 5.4 +/- A 3.8A degrees; L3-4, 4.3 +/- A 3.4A degrees; L4-5, 1.9 +/- A 1.1A degrees, respectively). During bending activity, the L4-5 had a higher (but not significant) range of left-right bending motion (4.7 +/- A 2.4A degrees) than both L2-3 (2.9 +/- A 2.4A degrees) and L3-4 (3.4 +/- A 2.1A degrees), while no statistical difference was observed in left-right twisting among the three vertebral levels (L2-3, 2.5 +/- A 2.3A degrees; L3-4, 2.4 +/- A 2.6A degrees; and L4-5, 2.9 +/- A 2.1A degrees, respectively). Besides the primary rotations reported, coupled motions were quantified in all DOFs. The coupled translation in left-right and anterior-posterior directions, on average, reached greater than 1 mm, while in the proximal-distal direction this was less than 1 mm. Overall, each vertebral level responds differently to flexion-extension and left-right bending, but similarly to the left-right twisting. This data may provide new insight into the in vivo function of human spines and can be used as baseline data for investigation of pathological spine kinematics.

AB Acinar cells in pancreatitis die through apoptosis and necrosis, the roles of which are different. The severity of experimental pancreatitis correlates directly with the extent of necrosis and inversely, with apoptosis. Apoptosis is mediated by the release of cytochrome c into the cytosol followed by caspase activation, whereas necrosis is associated with the mitochondrial membrane potential (Delta Psi m) loss leading to ATP depletion. Here, we investigate the role of Bcl-2 proteins in apoptosis and necrosis in pancreatitis. We found tip-regulation of prosurvival Bcl-2 proteins in pancreas in various experimental models of acute pancreatitis, most pronounced for Bcl-xL. This up-regulation translated into increased levels of Bcl-xL and Bcl-2 in pancreatic mitochondria. Bcl-xL/Bcl-2 inhibitors induced Delta Psi m loss and cytochrome c release in isolated mitochondria. Corroborating the results On mitochondria, Bcl-xL/Bcl-2 inhibitors induced Delta Psi m loss, NIT depletion and necrosis in pancreatic acinar cells, both untreated and hyperstimulated with CCK-8 (in vitro pancreatitis model). Together Bcl-xL/Bcl-2 inhibitors and CCK induced more necrosis than either treatment alone. Bcl-xL/Bcl-2 inhibitors also stimulated cytochrome c release in acinar cells leading to caspase-3 activation and apoptosis. However, different from their effect on pronecrotic signals, the Stimulation by Bcl-xL/Bcl-2 inhibitors of apoptotic responses was less in CCK-treated than control cells. Therefore, Bcl-xL/Bcl-2 inhibitors potentiated CCK-induced necrosis but not apoptosis. Correspondingly, transfection with Bcl-xL siRNA stimulated necrosis but not apoptosis in the in vitro pancreatitis model. Further, in animal models of pancreatitis Bcl-xL up-regulation inversely correlated with necrosis, but not apoptosis. Results indicate that Bcl-xL and Bcl-2 protect acinar cells from necrosis in pancreatitis by stabilizing mitochondria against death signals. We conclude that Bcl-xL/Bcl-2 inhibition would aggravate acute pancreatitis, whereas Bcl-xL/Bcl-2 up-regulation presents a strategy to prevent or attenuate necrosis in pancreatitis.

AB Significant advances in the diagnosis and treatment of brain tumors have been made through better imaging, surgical techniques and advances in radiation therapy. However, the cure rate for most adult and pediatric brain tumor patients has not mirrored this success. Angiogenesis, the development of neovascularization, provides the required nutrients and oxygen to an expanding tumor and is controlled by a complex balance of proangiogenic cytokines and antiangiogenic factors. A series of new inhibitors of angiogenesis are now in clinical trials. Most of these rely on inhibiting tumor cell-mediated cytokines or blocking the activation of their cognate receptors. Cytotoxic chemotherapy, by contrast, targets dividing cells but can be modulated to attack dividing endothelial cells. This review will focus on the use of low-dose antiangiogenic (also called metronomic) chemotherapy to inhibit endothelial cell function and resultant neovascularization in the treatment of adult and pediatric brain tumors. By examining the biology and preclinical findings that led to the development of antiangiogenid metronomic chemotherapy, clinical studies have been undertaken that support the role of this approach in the clinic, and have led to the introduction of a number of markers being used to better predict active combinations and appropriate patient populations.

AB Peripheral arterial disease is an underecognized manifestation of systemic atherosclerosis associated with high rates of cardiovascular morbidity and mortality. The rationale of therapy is to reduce cardiovascular risk, improve symptoms of intermittent claudication, and prevent the development of critical limb ischemia and amputation. Exercise therapy and several pharmacologic agents have been shown to improve walking distance in patients with intermittent claudication. Patients with lifestyle-interfering symptoms despite exercise, or those who progress to critical limb ischemia, frequently undergo revascularization. Endovascular techniques are commonly used in these patients. Combined pharmacological and endovascular strategies will play an increasing role in management of these patients in the future.

AB Despite steady progress in identifying quantitative trait loci (QTLs) for bone phenotypes, relatively little progress has been made in moving from QTLs to identifying the relevant gene. We exploited the genetic structure of recombinant congenic mouse strains by performing a reciprocal intercross of the strains HcB-8 and HcB-23, phenotyped for body size, femoral biomechanical performance, and femoral diaphyseal geometry and mapped with R/qtl and QTL Cartographer. Significant QTLs are present on chromosomes 1, 2, 3, 4, 6, and 10. We found significant sex x QTL and cross-direction x QTL interactions. The chromosome 4 QTL affects multiple femoral anatomic features and biomechanical properties. The known segregating segment of chromosome 4 contains only 18 genes, among which Ece1, encoding endothelin-converting enzyme 1, stands out as a candidate. Endothelin signaling has been shown to promote the growth of osteoblastic metastases and to potentiate signaling via the Wnt pathway. The colocalizing chromosome 4 QTL Bmd7 (for bone mineral density 7) increases responsiveness to mechanical loading. By exploiting the short informative segment of chromosome 4 and the known biology, we propose that Ece1 is the gene responsible for Bmd7 and that it acts by increasing responsiveness to mechanical loading through modulation of Wnt signaling.

AB Tissue-engineered models that mimic in vivo tissue organization offer the potential of capturing complex signaling pathways in vitro. In the liver, hepatocytes and endothelial cells are closely associated but separated by the extracellular matrix of the space of Disse. This unique configuration was mimicked by embedding primary hepatocytes in collagen gel and overlaying the matrix with endothelial cells. We demonstrate that during the first few days of culture, the secretion of albumin and fibrinogen was 2-fold higher in cocultures compared to hepatocytes alone. Hepatocyte function in both cultures stabilized to a similar level during the second week, suggesting that endothelial cells can induce the early recovery of hepatocytes after isolation and seeding. Endothelial cell-conditioned medium reproduced the effect of coculture in a dose-dependent fashion, suggesting a role for endothelial cell-derived soluble factors. Endothelial cell-conditioned medium increased mRNA levels of various acute-phase proteins such as albumin, fibrinogen, transferrin, and alpha-macroglobulin in hepatocytes. Surprisingly, the effect of endothelial cell-conditioned medium was not mediated by growth factors or cytokines, or by secreted extracellular matrix, but by the release of the amino acid proline, which mediates endogenous collagen synthesis by hepatocytes. These findings suggest an important role for proline secretion by endothelial cells as a paracrine factor regulating hepatocyte function.-Jindal, R., Nahmias, Y., Tilles, A.

AB Altered structure, and hence function, of cellular macromolecules caused by oxidation can contribute to loss of physiological function with age. Here, we tested whether the lifespan of bats, which generally live far longer than predicted by their size, could be explained by reduced protein damage relative to short-lived mice. We show significantly lower protein oxidation (carbonylation) in Mexican free-tailed bats (Tadarida brasiliensis) relative to mice, and a trend for lower oxidation in samples from cave myotis bats (Myotis velifer) relative to mice. Both species of bat show in vivo and in vitro resistance to protein oxidation under conditions of acute oxidative stress. These bat species also show low levels of protein ubiquitination in total protein lysates along with reduced proteasome activity, suggesting diminished protein damage and removal in bats. Lastly, we show that bat-derived protein fractions are resistant to urea-induced protein unfolding relative to the level of unfolding detected in fractions from mice. Together, these data suggest that long lifespan in some bat species might be regulated by very efficient maintenance of protein homeostasis.-Salmon, A.

AB The purpose of this study was to determine the effectiveness of vibrotactile feedback of body tilt in improving dynamic gait index (DGI) a fall risk indicator in community dwelling older adults. Twelve healthy elderly subjects (three males and nine females, age 79.7 +/- 5.4 yrs) were tested in an institutional balance rehabilitation laboratory to investigate changes between the feedback off and on conditions. Subjects were acutely exposed to a vibrotactile display that indicated the magnitude and direction of their body tilt from the vertical. DGI and mediolateral (ML) sway were determined during locomotion with, and without, vibrotactile tilt feedback (VTTF). All subjects were at risk for falls based on their initial DGI Score (range: 1519, mean 17.4 +/- 1.56), which was taken with the vibratory stimulus turned off. Subjects learned to use the trunk tilt information from the vibrotactile feedback vest through 20-30 min of gait and balance training consisting of activities that challenged their balance. Subjects were then retested on the DGI. Statistically significant changes were demonstrated for the DGI total score while using the vibrotactile tilt feedback. DGI total scores improved from 17.1 +/- 0.4 to 20.8 +/- 0.3 (p < 0.05). We conclude that vibrotactile tilt feedback improves both control of mediolateral sway during gait and dynamic gait index. Both are fall risk indicators for this population. (C) 2009 Elsevier B.V. All rights reserved.

AB BACKGROUND & AIMS: Goblet cells (GC) facilitate mucosal protection and epithelial barrier repair, yet the innate immune mechanisms that selectively drive GC functions have not been defined. The aim of this study was to determine whether Toll-like receptor (TLR) 2 and modulation of GC-derived trefoil factor (TFF) 3 are functionally linked in the intestine. METHODS: GC modulation was assessed using quantitative real-rime polymerase chain reaction analysis (qRT-PCR), Western blotting, and confocal microscopy Dextran sulfate sodium (DSS) colitis was induced in wild-type, TFF3(-/-), and TLR2(-/-) mice. Recombinant TLR2 ligand or TFF3 peptide were orally administered after DSS termination. Caco-2 cells overexpressing full-length TLR2 or mutant TLR2-R7S3Q were tested for TFF3 synthesis and functional-related effects in a Wounding assay. RESULTS: Data from in vitro (Ls174T) and ex vivo models of murine and human GC reveal that TLR2 activation selectively induces synthesis of TFF3. In vivo studies using TFF3-/- or TLR2-/- mice demonstrate the ability for oral treatment with a TLR2 agonist to confer antiapoptotic protection of the intestinal mucosa against inflammatory stress-induced damage through TFF3. Recombinant TFF3 rescues TLR2-deficient mice from increased morbidity and mortality during acute colonic injury. Severe ulcerative colitis (UC) has recently been found to be associated with the R753Q polymorphism of the TLR2 gene. The relevance of the observed functional effect of TLR2 in regulating GC is confirmed by the finding that the UC-associated TLR2R753Q variant is functionally deficient in the ability to induce TFF3 synthesis, thus leading to impaired wound healing. CONCLUSIONS: These data demonstrate a novel function of TLR2 in intestinal GC that links products of commensal bacteria to innate immune protection of the host via TFF3.

AB BACKGROUND & AIMS: Lymphocytes primed by intestinal dendritic cells (DC) express the gut-homing receptors CCR9 and alpha 4 beta 7, which recognize CCL25 and mucosal addressin cell-adhesion molecule-1 in the intestine promoting the development of regional immunity. In mice, imprinting of CCR9 and alpha 4 beta 7 is dependent on retinoic acid during T-cell activation. Tissue specificity is lost in primary sclerosing cholangitis (PSC), an extra-intestinal manifestation of inflammatory bowel disease, when ectopic expression of mucosal addressin cell-adhesion molecule-1 and CCL25 in the liver promotes recruitment of CCR9+alpha 4 beta 7+ T cells to the liver. We investigated the processes that control enterohepatic T-cell migration and whether the ability to imprint CCR9 and alpha 4 beta 7 is restricted to intestinal DCs or can under some circumstances be acquired by hepatic DCs in diseases such as PSC. METHODS: Human and murine DCs from gut, liver, or portal lymph nodes and hepatic stellate cells were used to activate CD8 T cells. Imprinting of CCR9 and alpha 4 beta 7 and functional migration responses were determined. Crossover activation protocols assessed plasticity of gut homing. RESULTS: Activation by gut DCs imprinted high levels of functional CCR9 and alpha 4 beta 7 on naive CD8 T cells, whereas hepatic DCs and stellate cells proved inferior. Imprinting was RA dependent and demonstrated plasticity. CONCLUSIONS: Imprinting and plasticity of gut-homing human CD8 T cells requires primary activation or reactivation by gut DCs and is retinoic acid dependent. The inability of liver DCs to imprint gut tropism implies that alpha 4 beta 7+CCR9+ T cell that infiltrate the liver in PSC are primed in the gut.

AB Cancer of the rectum poses a complex therapeutic challenge because of its proximity to adjacent organs and anal sphincters. The addition of radiotherapy before surgical resection has been shown to confer good survival rates while preserving sphincter function. Nevertheless, radiation is associated with significant side effects. On the basis of our previous work showing that herpes simplex virus type-1 (HSV-1) preferentially infects human colon cancer, we set out to examine the oncolytic effect of HSV-1 on orthotopic rectal tumors in mice. Two vectors were compared for oncolytic activity, HSV-1(G beta) with wild-type replication and an attenuated HSV-1 vector (HSV-G47 Delta). Intratumoral injection of HSV-1(G beta) and HSV-G47 Delta resulted in a significant reduction or disappearance of the tumors and increased survival of mice. Although the use of HSV-1(G beta) was associated with systemic toxicity, HSV-G47 Delta appears to possess a selective oncolytic activity. Moreover, infection with HSV-G47 Delta resulted in the activation of the double-stranded RNA-dependent protein kinase (PKR) pathway. A significant improvement in viral replication and the antitumor effect was observed when the PKR inhibitor 2-aminopurine was coadministered with HSV-G47 Delta to the tumor. In conclusion, the efficacy of local delivery of HSV-G47 Delta combined with a specific chemical inhibitor of antiviral activity points to a novel therapeutic modality for rectal cancer and other solid tumors.

AB Objective: This study evaluates whether depression is a risk factor for incident myocardial infarction (MI) in Department of Veterans Affairs (VA) patients with rheumatoid arthritis (RA) between 30 and 79 years of age.
Methods: We used a retrospective cohort study of 15,634 patients with RA. Diagnoses and sociodemographic data were obtained from VA administrative and pharmacy databases between fiscal years 1999 and 2006. Entry into the cohort required 2 years of patient time with no evidence of cardiovascular disease. Cox proportional hazard models with time-dependent covariates were computed to determine whether RA patients with depression as compared to RA patients without depression were at increased risk for MI during the maximum 6-year follow-up period.
Results: Unadjusted analyses indicated depressed RA patients were 1.4 times more likely than nondepressed RA patients to have an MI during follow-up. These results remained significant (HR=1.4; 95% CI: in the adjusted Cox proportional hazards model which included the effects of sociodemographics and known physical risks (e.g., diabetes) for MI.
Conclusions: Depressed RA patients, without a history of cardiovascular disease, are 40% more likely to have a heart attack as compared to those without depression. These data demonstrate a rapid (within 6 years) transition to MI following onset of depression in RA patients. Increased monitoring of depression and heart disease status in this patient population may be warranted which in turn may result in longer duration of life. Published by Elsevier Inc.

AB Genetic variation was first shown to be important in systemic lupus erythematosus (SLE or lupus) in the 1970s with associations in the human leukocyte antigen region. Almost four decades later, and with the help of increasingly powerful genetic approaches, more than 25 genes are now known to contribute to the mechanisms that predispose individuals to lupus. Over half of these loci have been discovered in the past 2 years, underscoring the extraordinary success of genome-wide association approaches in SLE. Well-established risk factors include alleles in the major histocompatibility complex region ( multiple genes), IRF5, ITGAM, STAT4, BLK, BANK1, PDCD1, PTPN22, TNFSF4, TNFAIP3, SPP1, some of the Fc gamma receptors, and deficiencies in several complement components, including C1q, C4 and C2. As reviewed here, many susceptibility genes fall into key pathways that are consistent with previous studies implicating immune complexes, host immune signal transduction and interferon pathways in the pathogenesis of SLE. Other loci have no known function or apparent immunological role and have the potential to reveal novel disease mechanisms. Certainly, as our understanding of the genetic etiology of SLE continues to mature, important new opportunities will emerge for developing more effective diagnostic and clinical management tools for this complex autoimmune disease.

AB We targeted LYN, a src-tyosine kinase involved in B-cell activation, in case-control association studies using populations of European-American, African-American and Korean subjects. Our combined European-derived population, consisting of 2463 independent cases and 3131 unrelated controls, shows significant association with rs6983130 in a female-only analysis with 2254 cases and 2228 controls (P = 1.1 x 10(-4), odds ratio (OR) = 0.81 (95% confidence interval: 0.73-0.90)). This single nucleotide polymorphism ( SNP) is located in the 50 untranslated region within the first intron near the transcription initiation site of LYN. In addition, SNPs upstream of the first exon also show weak and sporadic association in subsets of the total European-American population. Multivariate logistic regression analysis implicates rs6983130 as a protective factor for systemic lupus erythematosus (SLE) susceptibility when anti-dsDNA, anti-chromatin, anti-52 kDa Ro or anti-Sm autoantibody status were used as covariates. Subset analysis of the European-American female cases by American College of Rheumatology classification criteria shows a reduction in the risk of hematological disorder with rs6983130 compared with cases without hematological disorders (P = 1.5 x 10(-3), OR = 0.75 (95% CI: 0.62-0.89)). None of the 90 SNPs tested show significant association with SLE in the African American or Korean populations. These results support an association of LYN with European-derived individuals with SLE, especially within autoantibody or clinical subsets.

AB Genetic factors influence susceptibility to systemic lupus erythematosus (SLE). A recent family-based analysis in Caucasian and Chinese populations provided evidence for association of single-nucleotide polymorphisms (SNPs) in the complement receptor 2 (CR2/CD21) gene with SLE. Here we confirmed this result in a case-control analysis of an independent European-derived population including 2084 patients with SLE and 2853 healthy controls. A haplotype formed by the minor alleles of three CR2 SNPs (rs1048971, rs17615, rs4308977) showed significant association with decreased risk of SLE (30.4% in cases vs 32.6% in controls, P = 0.016, OR = 0.90 (0.82-0.98)). Two of these SNPs are in exon 10, directly 50 of an alternatively spliced exon preferentially expressed in follicular dendritic cells (FDC), and the third is in the alternatively spliced exon. Effects of these SNPs and a fourth SNP in exon 11 (rs17616) on alternative splicing were evaluated. We found that the minor alleles of these SNPs decreased splicing efficiency of exon 11 both in vitro and ex vivo. These findings further implicate CR2 in the pathogenesis of SLE and suggest that CR2 variants alter the maintenance of tolerance and autoantibody production in the secondary lymphoid tissues where B cells and FDCs interact.

AB Complement cascade plasma proteins play a complex role in the etiopathogenesis of systemic lupus erythematosus (SLE). Hereditary C1q deficiency has been strongly related to SLE; however, there are very few published SLE studies that evaluate the polymorphisms of genes encoding for C1q (A, B and C). In this study, we evaluated 17 single nucleotide polymorphisms (SNPs) across 37 kb of C1QA, C1QB and C1QC in a lupus cohort of individuals of the African-American and Hispanic origin. In a case-only analysis, a significant association at multiple SNPs in the C1QA gene was detected in African Americans with kidney nephritis (best P = 4.91 x 10(-6)). In addition, C1QA was associated with SLE in African Americans with a lack of nephritis and accompanying photosensitivity when compared with that in normal controls (P = 6.80 x 10(-6)). A similar trend was observed in the Hispanic subjects (P = 0.003). Quantitative analysis showed that some SNPs in C1q genes might be correlated with C3 complement levels in an additive model among African Americans (best P = 0.0001). The C1QA gene is associated with subphenotypes of lupus in the African-American and Hispanic subjects. Further studies with higher SNP densities in this region and other complement components are necessary to elucidate the complex genetics and phenotypic interactions between complement components and SLE.

TI Replication of the BANK1 genetic association with systemic lupus

ID GENOME-WIDE ASSOCIATION; VARIANTS; LINKAGE; ITGAM
AB Systemic lupus erythematosus (SLE) is an autoimmune disease with highly variable clinical presentation. Patients suffer from immunological abnormalities that target T-cell, B-cell and accessory cell functions. B cells are hyperactive in SLE patients. An adapter protein expressed in B cells called BANK1 (B-cell scaffold protein with ankyrin repeats) was reported in a previous study to be associated with SLE in a European population. The objective of this study was to assess the BANK1 genotype phenotype association in an independent replication sample. We genotyped 38 single nucleotide polymorphisms (SNPs) in BANK1 on 1892 European-derived SLE patients and 2652 European-derived controls. The strongest associations with SLE and BANK1 were at rs17266594 (corrected P-value = 1.97 x 10(-5), odds ratio (OR) = 1.22, 95% CI 1.12-1.34) and rs10516487 (corrected P-value = 2.59 x 10(-5), OR = 1.22, 95% CI 1.11-1.34). Our findings suggest that the association is explained by these two SNPs, confirming previous reports that these polymorphisms contribute to the risk of developing lupus. Analysis of patient subsets enriched for hematological, immunological and renal ACR criteria or the levels of autoantibodies, such as anti-RNP A and anti-SmRNP, uncovers additional BANK1 associations. Our results suggest that BANK1 polymorphisms alter immune system development and function to increase the risk for developing lupus.

AB The progressive loss of CNS myelin in patients with multiple sclerosis (MS) has been proposed to result from the combined effects of damage to oligodendrocytes and failure of remyelination. A common feature of demyelinated lesions is the presence of oligodendrocyte precursors (OLPs) blocked at a premyelinating stage. However, the mechanistic basis for inhibition of myelin repair is incompletely understood. To identify novel regulators of OLP differentiation, potentially dysregulated during repair, we performed a genome-wide screen of 1040 transcription factor-encoding genes expressed in remyelinating rodent lesions. We report that similar to 50 transcription factor-encoding genes show dynamic expression during repair and that expression of the Wnt pathway mediator Tcf4 (aka Tcf7l2) within OLPs is specific to lesioned-but not normal-adult white matter. We report that beta-catenin signaling is active during oligodendrocyte development and remyelination in vivo. Moreover, we observed similar regulation of Tcf4 in the developing human CNS and lesions of MS. Data mining revealed elevated levels of Wnt pathway mRNA transcripts and proteins within MS lesions, indicating activation of the pathway in this pathological context. We show that dysregulation of Wnt-beta-catenin signaling in OLPs results in profound delay of both developmental myelination and remyelination, based on (1) conditional activation of beta-catenin in the oligodendrocyte lineage in vivo and (2) findings from APC(Min) mice, which lack one functional copy of the endogenous Wnt pathway inhibitor APC. Together, our findings indicate that dysregulated Wnt-beta-catenin signaling inhibits myelination/remyelination in the mammalian CNS. Evidence of Wnt pathway activity in human MS lesions suggests that its dysregulation might contribute to inefficient myelin repair in human neurological disorders.

AB Telomeric regions are known to be transcribed in several organisms. Although originally reported to be transcribed from all chromosomes with enrichment near the inactive X of female cells, we show that telomeric RNAs in fact are enriched oil both sex chromosomes of the mouse in a developmentally specific manner. In female stem cells, 13001 active Xs are marked by the RNAs. In male stem cells, both the X and the Y accumulate telomeric RNA. Distribution of telomeric RNAs changes during cell differentiation, after which they associate only with the heterochromatic sex chromosomes of each sex. FISH mapping suggests that accumulated telomeric RNAs localize at the distal telomeric end. Interestingly, telomeric expression changes in cancer and during cellular stress. Furthermore, RNA accumulation increases in Dicer-deficient stem cells, suggesting direct or indirect links to RNAi. We propose that telomeric RNAs are tied to cell differentiation and may be used to mark pluripotency and disease.

AB Purpose: The goal of this project was to assess genetic/genomic content in electronic health records. Methods: Semistructured interviews were conducted with key informants. Questions addressed documentation, organization, display, decision support and security of family history and genetic test information, and challenges and opportunities relating to integrating genetic/genomics content in electronic health records. Results: There were 56 participants: 10 electronic health record specialists, 18 primary care clinicians, 16 medical geneticists, and 12 genetic counselors. Few clinicians felt their electronic record met their current genetic/genomic medicine needs. Barriers to integration were mostly related to problems with family history data collection, documentation, and organization. Lack of demand for genetics content and privacy concerns were also mentioned as challenges. Data elements and functionality requirements that clinicians see include: pedigree drawing; clinical decision support for familial risk assessment and genetic testing indications; a patient portal for patient-entered data; and standards for data elements, terminology, structure, interoperability, and clinical decision support rules. Although most said that there is little impact of genetics/genomics on electronic records today, many stated genetics/genomics would be a driver of content in the next 5-10 years. Conclusions: Electronic health records have the potential to enable clinical integration of genetic/genomic medicine and improve delivery of personalized health care; however, structured and standardized data elements and functionality requirements are needed.

TI Shifted Transversal Design smart-pooling for high coverage interactome
mapping

RESOURCE; BIOLOGY; MAP
AB "Smart-pooling,'' in which test reagents are multiplexed in a highly redundant manner, is a promising strategy for achieving high efficiency, sensitivity, and specificity in systems-level projects. However, previous applications relied on low redundancy designs that do not leverage the full potential of smart-pooling, and more powerful theoretical constructions, such as the Shifted Transversal Design (STD), lack experimental validation. Here we evaluate STD smart-pooling in yeast two-hybrid (Y2H) interactome mapping. We employed two STD designs and two established methods to perform ORFeome-wide Y2H screens with 12 baits. We found that STD pooling achieves similar levels of sensitivity and specificity as one-on-one array-based Y2H, while the costs and workloads are divided by three. The screening-sequencing approach is the most cost- and labor-efficient, yet STD identifies about twofold more interactions. Screening-sequencing remains an appropriate method for quickly producing low-coverage interactomes, while STD pooling appears as the method of choice for obtaining maps with higher coverage.

AB We employed ABI high-density oligonucleotide microarrays containing 31,700 sixty-mer probes (representing 27,868 annotated human genes) to determine differential gene expression in idiopathic dilated cardiomyopathy (DCM). We identified 626 up-regulated and 636 down-regulated genes in DCM compared to controls. Most significant changes occurred in the tricarboxylic acid cycle, angiogenesis, and apoptotic signaling pathways, among which 32 apoptosis- and 13 MAPK activity-related genes were altered. Inorganic cation transporter, catalytic activities, energy metabolism and electron transport-related processes were among the most critically influenced pathways. Among the up-regulated genes were HTRA1 (6.9-fold), PDCD8(AIFM1) (5.2) and PRDX2 (4.4) and the clown-regulated genes were NR4A2 (4.8), MX1 (43), LGALS9 (4), IFNA13 (4), UNC5D (3.6) and HDAC2 (3) (p<0.05), all of which have no clearly defined cardiac-related function yet. Gene ontology and enrichment analysis also revealed significant alterations in mitochondrial oxidative phosphorylation, metabolism and Alzheimer's disease pathways. Concordance was also confirmed for a significant number of genes and pathways in an independent validation microarray dataset. Furthermore, verification by real-time RT-PCR showed a high degree of consistency with the microarray results. Our data demonstrate an association of DCM with alterations in various cellular events and multiple yet undeciphered genes that may contribute to heart muscle disease pathways. (C) 2009 Elsevier Inc.

AB Chronic open-angle glaucoma is a leading cause of blindness and visual impairment in older adults. Optic nerve damage and the associated peripheral and subsequent central vision loss are irreversible, but early diagnosis and treatment will give patients the best chance to maintain functional vision and quality of life. Primary care physicians can assist with the diagnosis of glaucoma by making appropriate referrals for routine ophthalmic examinations, especially in patients with risk factors for glaucoma. Medication adherence and persistence may also be enhanced by discussing strategies to improve medication use and efficacy in the primary care setting. Recognition of adverse reactions from glaucoma medications and surgeries will allow proper management of these potentially serious conditions. Patients with advanced visual deficits can still benefit from treatment as well as low-vision and supportive care and should be referred for an ophthalmic evaluation. With an understanding of comprehensive glaucoma management, primary care physicians play an invaluable role in assisting their patients with effective and timely therapy that will result in improved outcomes.

AB Objectives. Granulosa cell tumors (GCTs) comprise 2-5% of ovarian tumors. Serum Mullerian Inhibiting Substance (MI5, also known as anti-Mullerian hormone, or AMH) levels have been validated as a marker of GCT recurrence and progression. There has been little correlation between serum MIS/AMH levels and several clinical parameters in GCTs, including tumor burden. We have performed a retrospective review correlating aggregate tumor mass as reported by pathologic examination or by radiology with serum MIS/AMH levels drawn on the date of examination.
Methods. We retrospectively identified 32 GCT patients at our institution over the last 15 years who had serum MIS/AMH measurements. Patients who had serum MIS/AMH measurements within three days of surgery or on the same day as abdominal computerized tomography scan (CT) or magnetic resonance imaging (MRI) were further evaluated.
Results. We found a significant direct correlation between patient serum MIS/AMH levels and gross aggregate tumor mass determined by pathology (slope = 15.4 +/- 6.06, r = 0.65, p < 0.04) or by radiographic aggregate tumor mass for all data points identified (slope = 0.07 +/- 0.03, r = 0.33, p < 0.04) and after correcting for selection bias (slope = 1.45 +/- 0.17, r = 0.93, p < 0.01). We also identified a significant difference between serum MIS/AMH levels between samples drawn the same day as negative and positive abdominal CT or MRI scans (8.16 +/- 1.54 vs. 158.7 +/- 32.2 ng/ml, p < 0.0001).
Conclusions. These data indicate a significant direct correlation between serum MIS/AMH levels and both gross and radiographic aggregate tumor mass in GCT patients. Together with the current literature, the present data argue for a more prominent role for serum MIS/AMH in the management of GCTs. (C) 2009 Elsevier Inc. All rights reserved.

AB Lamivudine prophylaxis is an effective strategy in HbSAg-positive patients receiving cancer chemotherapy. Recent data indicate that a lamividune-prophylaxis strategy results in a decrease of hepatitis B virus (HBV) reactivation rates, though its effect on HBV-mortality remains equivocal. This report evaluates the benefits from this strategy among lymphoma patients and develops a management approach for patients with prolonged immunosuppression. A Medline search was conducted to retrieve published trials on HBsAg-positive lymphoma patients receiving prophylactic lamivudine during chemotherapy. Basic inclusion criterion was to report HBV-reactivation rates with and without lamivudine prophylaxis. A meta-analysis of the risk of HBV-reactivation and HBV-related mortality was conducted, and the pooled effect was calculated as risk ratio (RR). We found that lamivudine prophylaxis is associated with a significant reduction in hepatitis B virus reactivation (RR 0.21, 95%CI 0.13-0.35) and a trend in reducing HBV-related mortality (RR 0.68, 95%CI 0.192.49). In order to study the long-term effects of anti-HBV prophylaxis when prolonged immunosuppression is needed, we used our findings to model a decision tree. Overall survival was the main outcome used in the analysis. Rituximab maintenance in B-cell lymphomas was used as a paradigm of prolonged immunosuppression. We found that extended anti-HBV prophylaxis can improve survival rates by 2.4% in HBsAg-positive patients. If 1,000 HBsAg-positive lymphoma patients receive prophylaxis, one will die from hepatitis B virus reactivation versus 25/1,000 if no prophylaxis is administered. This effect is probably mediated through a reduction of hepatitis B virus reactivation and HBV-related mortality. The ideal antiviral agent needs to be determined.

ID RADIOFREQUENCY ABLATION; FISTULA
AB BACKGROUND Cryoenergy is being increasingly used for atrial fibrillation (AF) ablation, but the thermal effect of cryoenergy on the esophagus remains undefined.
OBJECTIVE This study examines the esophageal effects of cryoenergy used during AF ablation.
METHODS Catheter ablation was performed using a cryoballoon catheter in 67 AF patients (Cryoballoon group), and a spot cryocatheter to complete irrigated radiofrequency lesion sets at segments in close proximity to the esophagus in 7 AF patients (Cryo-Focal group). A temperature probe monitored the luminal esophageal temperature (LET) in all patients; LET changes did not guide therapy. Post-procedural endoscopy was performed on 35 of 67 (52%) Cryoballoon and all Cryo-Focal patients.
RESULTS Significant LET decreases (>1 degrees C) occurred in 62 of 67 (93%) Cryoballoon patients. LET continued to decrease after termination of cryoablation before recovering to normal. Temperature decreases were more pronounced during ablation at the inferior (3.1 degrees C) than superior pulmonary veins (1.5 degrees C); the lowest observed temperature was 0 degrees C. Post-procedural endoscopy showed esophageal ulcerations in 6 of 35 (17%) patients. There were no atrial-esophageal fistulas, and all ulcers had heated on follow-up endoscopy. Patients with and without ulceration differed with respect to mean LET nadir, cumulative LET decrease, and number of LETs <30 degrees C. In the Cryo-Focat group, 6 2 spot cryolesions per patient resulted in 1.3 +/- 1 LET decreases per patient, and an absolute nadir of 32.5 degrees C.
CONCLUSION Cryoballoon ablation can cause significant LET decreases, resulting in reversible esophageal ulcerations in 17% of patients. No ulcerations occurred with adjunctive spot cryoablation at regions near the esophagus during radiofrequency ablation procedures.

AB Despite data that traditional laboratory-based outcome measures in dialysis are improving over time, population-based data indicate that mortality rates are not improving in parallel. With increased focus on performance measures based on laboratory-based outcomes (e.g., hematocrit, albumin, and parathyroid hormone), less emphasis has been placed on other markers, some of which may be stronger predictors of mortality. We performed a systematic review to interpret the predictive value of laboratory-based outcome measures in dialysis. We identified studies with data regarding the predictive value of laboratory-based outcomes for mortality in dialysis. We calculated the sample size-weighted pooled relative risk of death with dichotomized "high" vs. "low" levels of each measure. We rank-ordered predictors by scaling the pooled relative risk of each measure by its pooled standard deviation. There were 5171 titles, of which 128 (representing 44 laboratory-based outcomes) were selected. Nine were significantly associated with mortality, in order of decreasing scaled effect size: (1) tumor necrosis factor-alpha, (2) hematocrit, (3) interleukin-6, (4) troponin T, (5) Kt/V(urea), (6) prealbumin, (7) urea reduction ratio, (8) serum albumin, and (9) C-reactive protein. Other oft-cited measures such as calcium phosphate product and parathyroid hormone were not significantly associated with mortality in pooled analysis. Quality improvement efforts to improve traditional laboratory-based outcomes in end-stage renal disease are necessary, but likely insufficient, to improve overall mortality in dialysis. Renewed consideration of cardiovascular, inflammatory, and nutritional markers that are especially strong predictors of mortality may have important implications for risk stratification and targeted therapeutic interventions.

AB Little is known about the impact of dietary factors on the progression of liver disease. Our aim was to determine whether dietary intake was associated with the risk of cirrhosis-related or liver cancer-related death or hospitalization in the U.S. population. Participants included 9221 persons aged 25-74 years without evidence of cirrhosis at entry into the study or during the first 5 years of follow-up, who were subsequently followed for a mean of 13.3 years as part of the first National Health and Nutrition Examination Survey. Dietary intake was ascertained at baseline using a 24-hour dietary recall questionnaire. During follow-up, 123 of 9221 participants had a diagnosis of cirrhosis (n = 118) or liver cancer (n = 5) in hospitalization records or death certificates, including 36 who were diagnosed only on the basis of death certificates. Participants who reported a diet high in protein were at a higher risk of hospitalization or death due to cirrhosis or liver cancer (P = 0.001), whereas those who reported a diet high in carbohydrates were at a lower risk (P = 0.003), after adjusting for potential confounders (daily consumption of protein, carbohydrate, fat, tea or coffee, and alcohol, gender, race, age, educational attainment, U.S. geographical region, diabetes, body mass index, and subscapular-to-triceps skinfold ratio). Although total fat consumption was not significantly associated with the risk of cirrhosis or liver cancer, cholesterol consumption was associated with higher risk (P = 0.007), whereas serum cholesterol level was not associated with risk of cirrhosis or liver cancer. Conclusion: Diet may be an important and potentially modifiable determinant of liver disease. (HEPATOLOGY 2009;50:175-184.)

AB Animal findings have highlighted the modulatory role of phasic dopamine (DA) signaling in incentive learning, particularly in the acquisition of reward-related behavior. In humans, these processes remain largely unknown. In a recent study, we demonstrated that a single low dose of a D2/D3 agonist (pramipexole)-assumed to activate DA autoreceptors and thus reduce phasic DA bursts-impaired reward learning in healthy subjects performing a probabilistic reward task. The purpose of this study was to extend these behavioral findings using event-related potentials and computational modeling. Compared with the placebo group, participants receiving pramipexole showed increased feedback-related negativity to probabilistic rewards and decreased activation in dorsal anterior cingulate regions previously implicated in integrating reinforcement history over time. Additionally, findings of blunted reward learning in participants receiving pramipexole were simulated by reduced presynaptic DA signaling in response to reward in a neural network model of striatal-cortical function. These preliminary findings offer important insights on the role of phasic DA signals on reinforcement learning in humans and provide initial evidence regarding the spatiotemporal dynamics of brain mechanisms underlying these processes.

AB Tasks employing parametric variation in movement rate are associated with predictable modulations in neural activity and provide a convenient context for developing new techniques for system identification. Using a multistage approach, we explored the functional and effective connectivity of a visuomotor control system by combining generalized partial least squares (gPLS) with subsequent structural equation modeling (SEM) to reveal the relationships between neural activity and finger movement rate in an experiment involving visually paced left or right thumb flexion. The gPLS in the first analysis stage automatically identified spatially distributed sets of BOLD-contrast signal changes using linear combinations of sigmoidal basis functions parameterized by kinematic variables. The gPLS provided superior sensitivity in detecting task-related functional activity patterns via a step-wise comparison with both classical linear modeling and behavior correlation analysis. These activity patterns were used in the second analysis stage, which employed SEM to characterize the areal regional interactions. The hybrid gPLS/SEM procedure allowed modeling of complex regional interactions in a network including primary motor cortex, premotor areas, cerebellum, thalamus, and basal ganglia, with differential activity modulations with respect to rate observed in the corticocerebellar and corticostriate subsystems. This effective connectivity analysis of visuomotor control circuits showed that both the left and right corticocerebellar and corticostriate circuits exhibited movement rate-related modulation. The identification of the functional connectivity among regions participating particular classes of behavior using gPLS, followed by the estimation of the effective connectivity using SEM is an efficient means to characterize the neural interactions underlying variations in sensorimotor behavior.

AB Attention-deficit/hyperactivity disorder, ADHD, is a common and highly heritable neuropsychiatric disorder that is seen in children and adults. Although heritability is estimated at around 76%, it has been hard to find genes underlying the disorder. ADHD is a multifactorial disorder, in which many genes, all with a small effect, are thought to cause the disorder in the presence of unfavorable environmental conditions. Whole genome linkage analyses have not yet lead to the identification of genes for ADHD, and results of candidate gene-based association studies have been able to explain only a tiny part of the genetic contribution to disease, either. A novel way of performing hypothesis-free analysis of the genome suitable for the identification of disease risk genes of considerably smaller effect is the genome-wide association study (GWAS). So far, five GWAS have been performed on the diagnosis of ADHD and related phenotypes. Four of these are based on a sample set of 958 parent-child trio's collected as part of the International Multicentre ADHD Genetics (IMAGE) study and genotyped with funds from the Genetic Association Information Network (GAIN). The other is a pooled GWAS including adult patients with ADHD and controls. None of the papers reports any associations that are formally genome-wide significant after correction for multiple testing. There is also very limited overlap between studies, apart from an association with CDH13, which is reported in three of the studies. Little evidence supports an important role for the 'classic' ADHD genes, with possible exceptions for SLC9A9, NOS1 and CNR1. There is extensive overlap with findings from other psychiatric disorders. Though not genome-wide significant, findings from the individual studies converge to paint an interesting picture: whereas little evidence-as yet-points to a direct involvement of neurotransmitters (at least the classic dopaminergic, noradrenergic and serotonergic pathways) or regulators of neurotransmission, some suggestions are found for involvement of 'new' neurotransmission and cell-cell communication systems. A potential involvement of potassium channel subunits and regulators warrants further investigation. More basic processes also seem involved in ADHD, like cell division, adhesion (especially via cadherin and integrin systems), neuronal migration, and neuronal plasticity, as well as related transcription, cell polarity and extracellular matrix regulation, and cytoskeletal remodeling processes. In conclusion, the GWAS performed so far in ADHD, though far from conclusive, provide a first glimpse at genes for the disorder. Many more (much larger studies) will be needed. For this, collaboration between researchers as well as standardized protocols for phenotyping and DNA-collection will become increasingly important.

AB A recent study reported an association between the brain natriuretic peptide (BNP) promoter T-381C polymorphism (rs198389) and protection against type 2 diabetes (T2D). As replication in several studies is mandatory to confirm genetic results, we analyzed the T-381C polymorphism in seven independent case-control cohorts and in 291 T2D-enriched pedigrees totalling 39 557 subjects of European origin. A meta-analysis of the seven case-control studies (n = 39 040) showed a nominal protective effect [odds ratio (OR) = 0.86 (0.79-0.94), P = 0.0006] of the CC genotype on T2D risk, consistent with the previous study. By combining all available data (n = 49 279), we further confirmed a modest contribution of the BNP T-381C polymorphism for protection against T2D [OR = 0.86 (0.80-0.92), P = 1.4 x 10(-5)]. Potential confounders such as gender, age, obesity status or family history were tested in 4335 T2D and 4179 normoglycemic subjects and they had no influence on T2D risk. This study provides further evidence of a modest contribution of the BNP T-381C polymorphism in protection against T2D and illustrates the difficulty of unambiguously proving modest-sized associations even with large sample sizes.

AB Methylmalonic aciduria and homocystinuria, cblC type, is a rare disorder of intracellular vitamin B(12) (cobalamin [Cbl]) metabolism caused by mutations in the MMACHC gene. MMACHC was sequenced from the gDNA of 118 cblC individuals. Eleven novel mutations were identified, as well as 23 mutations that were observed previously. Six sequence variants capture haplotype diversity in individuals across the MMACHC interval. Genotype-phenotype correlations of common mutations were apparent; individuals with c.394C > T tend to present with late-onset disease whereas patients with c.331C > T and c.271dupA tend to present in infancy. Other missense variants were also associated with late- or early-onset disease. Allelic expression analysis was carried out on human cblC fibroblasts compound heterozygous for different combinations of mutations including c.271dupA, c.331C > T, c.394C > T, and c.482G > A. The early-onset c.271dupA mutation was consistently underexpressed when compared to control alleles and the late-onset c.394C > T and c.482G > A mutations. The early-onset c.331C > T mutation was also underexpressed when compared to control alleles and the c.394C > T mutation. Levels of MMACHC mRNA transcript in cell lines homozygous for c.271dupA, c.331C > T, and c.394C > T were assessed using quantitative real-time RT-PCR. Cell lines homozygous for the late onset c.394C > T mutation had significantly higher levels of transcript when compared to cell lines homozygous for the early-onset mutations. Differential or preferential MMACHC transcript levels may provide a clue as to why individuals carrying c.394C > T generally present later in life. Hum Mutat 30:1072-1081, 2009.

AB We used data from the National Birth Defects Prevention Study, a population-based, case-control study, to examine whether previously reported associations between antihypertensive medications and cardiovascular malformations could be confirmed and to explore whether new associations might be identified. Cases (n = 5021) were ascertained through birth defects surveillance systems from 1997 through 2003 in 10 US states. Controls (n = 4796) were live births without birth defects selected randomly from birth certificates or hospital discharge listings in the same geographic regions. Logistic regression was used to examine the relationship between antihypertensive medication treatment and the occurrence of cardiovascular malformations while controlling for confounding variables. First-trimester treatment with antihypertensive medication was associated with pulmonary valve stenosis (odds ratio [OR]: 2.6; 95% CI: 1.3 to 5.4), Ebstein malformation (crude OR: 11.4; exact 95% CI: 2.8 to 34.1), coarctation of the aorta (OR: 3.0; 95% CI: 1.3 to 6.6), and secundum atrial septal defects (OR: 2.4; 95% CI: 1.3 to 4.4). Treatment initiated after the first trimester was associated with pulmonary valve stenosis (OR: 2.4; 95% CI: 1.1 to 5.4), perimembranous ventricular septal defects (OR: 2.3; 95% CI: 1.2 to 4.6), and secundum atrial septal defects (OR: 2.4; 95% CI: 1.3 to 4.4). Untreated hypertension was associated with Ebstein malformation (OR: 2.1; 95% CI: 1.0 to 4.3) and secundum atrial septal defects (OR: 1.3; 95% CI: 1.0 to 1.6). Antihypertensive medication use and/or the underlying hypertension might increase the risk of having an infant with specific left and right obstructive and septal defects. Additional studies with adequate power will be needed to confirm these findings. (Hypertension. 2009; 54: 63-70.)

AB Tracking the autonomic control and respiratory sinus arrhythmia (RSA) from electrocardiogram and respiratory measurements is an important problem in cardiovascular control. We propose a point process adaptive filter algorithm based on an inverse Gaussian model to track heart beat intervals that incorporates respiratory measurements as a covariate and provides an analytic form for computing a dynamic estimate of RSA gain. We use Kolmogorov-Smirnov tests and autocorrelation function analyses to assess model goodness-of-fit. We illustrate the properties of the new dynamic estimate of RSA in the analysis of simulated heart beat data and actual heart beat data recorded from subjects in a four-state postural study of heart beat dynamics: control, sympathetic blockade, parasympathetic blockade, and combined sympathetic and parasympathetic blockade. In addition to giving an accurate description of the heart beat data, our adaptive filter algorithm confirms established findings pointing at a vagally mediated RSA and provides a new dynamic RSA estimate that can be used to track cardiovascular control between and within a broad range of postural, pharmacological, and age conditions. Our paradigm suggests a possible framework for designing a device for ambulatory monitoring and assessment of autonomic control in both laboratory research and clinical practice.

AB In this paper, a novel low-complexity antenna-selection algorithm based on a constrained adaptive Markov chain Monte Carlo (CAMCMC) optimization method is proposed to approach the maximum capacity or minimum bit error rate (BER) of receive-antenna-selection multiple-input multiple-output (MIMO)-orthogonal frequency division multiplexing (OFDM) systems. We analyze the performance of the proposed system as the control parameters are varied and show that both the channel capacity and the system BER achieved by the proposed CAMCMC selection algorithm are close to the optimal results obtained by the exhaustive search (ES) method. We further demonstrate that this performance can be achieved with less than 1% of the computational complexity of the ES rule and is independent of the antenna-selection criteria, outage rate requirements, antenna array configuration, and channel frequency selectivity. Similar to the existing antenna-selection algorithms, both channel capacity and system BER improvements achieved by the proposed CAMCMC method are reduced as the channel frequency selectivity increases. Therefore, we conclude that, whether it is designed to maximize the channel capacity or minimize the system BER, the CAMCMC-optimization-method-based antenna-selection technique is appropriate for a MIMO-OFDM system with low frequency selectivity.

AB Hypomorphic mutations in nuclear factor kappa B essential modulator (NEMO) cause X-linked ectodermal dysplasia with immunodeficiency (X-ED-ID). Clinical manifestations in boys with X-ED-ID apart from ectodermal dysplasia and immunodeficiency include osteopetrosis, lymphedema, and colitis. Further description of atypical findings in this disorder is needed. Treatment with allogeneic hematopoietic stem cell transplantation (HSCT) is in its infancy, and how or whether non-immune manifestations of defective NEMO function are impacted by HSCT is poorly described. We report an interesting case of a boy with NEMO mutation who had symptoms reminiscent of Omenn's syndrome and small intestinal villous atrophy with features reminiscent of tufting enteropathy. We describe his treatment course as well as reconstitution of immune function and correction of osteopetrosis post-HSCT, and review the cases of allogeneic HSCT reported to date in the literature.

AB Hematopoietic stem and progenitor cells (HSPCs) are a rare population of precursor cells that possess the capacity for self-renewal and multilineage differentiation. In the bone marrow (BM), HSPCs warrant blood cell homeostasis. In addition, they may also replenish tissue-resident myeloid cells and directly participate in innate immune responses once they home to peripheral tissues. In this review, we summarize recent data on the signaling molecules that modulate the mobilization of HSPCs from BM and their migration to peripheral tissues.

AB Innate immunity is the earliest response to invading microbes and acts to contain infection in the first minutes to hours of challenge. Unlike adaptive immunity that relies upon clonal expansion of cells that emerge days after antigenic challenge, the innate immune response is immediate. Soluble mediators, including complement components and the mannose binding lectin (MBL) make an important contribution to innate immune protection and work along with epithelial barriers, cellular defenses such as phagocytosis, and pattern-recognition receptors that trigger pro-inflammatory signaling cascades. These four aspects of the innate immune system act in concert to protect from pathogen invasion. Our work has focused on understanding the protection provided by this complex defense system and, as discussed in this review, the particular contribution of soluble mediators such as MBL and phagocytic cells. Over the past two decades both human epidemiological data and mouse models have indicated that MBL plays a critical role in innate immune protection against a number of pathogens. As demonstrated by our recent in vitro work, we show that MBL and the innate immune signaling triggered by the canonical pattern-recognition receptors (PRRs), the Toll-like receptors (TLRs), are linked by their spatial localization to the phagosome. These observations demonstrated a novel role for MBL as a TLR co-receptor and establishes a new paradigm for the role of opsonins, which we propose to function not only to increase microbial uptake but also to spatially coordinate, amplify, and synchronize innate immune defenses mechanism. In this review we discuss both the attributes of MBL that make it a unique soluble pattern recognition molecule and also highlight its broader role in coordinating innate immune activation.

AB During evolution of the vertebrate cardiovascular system, the vast endothelial surface area associated with branching vascular networks mandated the development of molecular processes to efficiently and specifically recruit circulating sentinel host defense cells and tissue repair cells at localized sites of inflammation/tissue injury. The forces engendered by high-velocity blood flow commensurately required the evolution of specialized cell surface molecules capable of mediating shear-resistant endothelial adhesive interactions, thus literally capturing relevant cells from the blood stream onto the target endothelial surface and permitting subsequent extravasation. The principal effectors of these shear-resistant binding interactions comprise a family of C-type lectins known as 'selectins' that bind discrete sialofucosylated glycans on their respective ligands. This review explains the 'intelligent design' of requisite reagents to convert native CD44 into the sialofucosylated glycoform known as hematopoietic cell E-/L-selectin ligand (HCELL), the most potent E-selectin counter-receptor expressed on human cells, and will describe how ex vivo glycan engineering of HCELL expression may open the 'avenues' for the efficient vascular delivery of cells for a variety of cell therapies.

FX This article reviews over 20 years of laboratory effort seeking to
create strategies to deliver infused cells to a predetermined anatomic
site. The inspiration for this work derives from my patients undergoing
hematopoietic stem cell transplantation, where the problems of lack of
hematopoietic engraftment, infectious diseases (e.g. cytomegalovirus
disease) and recurrence of (primary) malignant disease posttransplant
(e.g. lymphoma, leukemia) made evident the imperative to optimize
vascular delivery of relevant cells (hematopoietic stem cells or immune
effector cells) to requisite (affected) sites in order to realize
long-term cure. Thus, I dedicate this review to my patients, alive and
deceased, for their lessons in courage and in humanity. Moreover, over
this period of time, many technicians, students, post-docs et al. have
contributed significantly to this mission. Certainly, there are no words
adequate to relay my gratitude for their devotion and commitment to this
endeavor. In typical acknowledgements found in scientific publications,
it is uncommon for one to thank the unsung heroes: teachers/mentors and
family. Regrettably, several mentors have departed - Ramzi S. Cotran,
Edgar Haber, Harvey R. Colten, Yee Hon Chin, J. Wayne Streilein, and
Robert A. Good - without ever knowing my eternal gratitude. I would thus
like to formally thank here Drs. Adel A. Yunis, Murray Epstein, Claude
P. Lechene, Emil R. Unanue, Lawrence M. Fishman, Gerald J. Elfenbein,
and E. Donnall Thomas, for their example, for sharing their infinite
wisdom, and for their constant encouragement and support. Last, but
certainly not least, I thank my parents, Harold and Rosalina Sackstein,
my wife, Beth, and my children, David and Danielle, without whom none of
this would be possible.; This work was supported in part by Veterans

AB This review discusses different mechanisms that result in immunological tolerance, such as intrathymic deletion of immature T cells, intrathymic and extrathymic generation of regulatory T cells, effector mechanisms of regulatory T cells as well as molecular pathways involved in extrathymic generation of regulatory T cells in vivo and in vitro. These molecular mechanisms should enable investigators to develop clinical protocols aiming at the specific prevention of unwanted immune responses, thereby replacing indiscriminate immunosuppression that often has fatal consequences.

AB Chronic alcoholism has profound effects on the brain, including volume reductions in regions critical for eyeblink classical conditioning (EBCC). The current study challenged abstinent alcoholics using delay (n = 20) and trace (n = 17) discrimination/reversal EBCC. Comparisons revealed a significant difference between delay and trace conditioning performance during reversal (t (35) = 2.08, p < 0.05). The difference between the two tasks for discrimination was not significant (p = 0.44). These data support the notion that alcoholics are increasingly impaired in the complex task of reversing a previously learned discrimination when a silent trace interval is introduced. Alcoholics' impairment in flexibly altering learned associations may be central to their continued addiction.

AB Background Neuropsychiatric symptoms (NPS) are common in patients with mild cognitive impairment (MCI). Little is known, however, about how NPS vary by MCI subtype (i.e. amnestic, single domain non-memory, and multiple domain). In addition, it is unclear whether NPS increase risk of progression to dementia. We investigated the distribution of NPS across MCI subtypes and determined whether NPS increase risk of progression to dementia.
Method Participants were 521 patients diagnosed with MCI at the Alzheimer's Research Centers of California between 1988 and 1999. At baseline, patients were classified into MCI subtypes and were assessed for NPS.
Results The mean number of NPS was 2.3 (range 0-9.6; 74% had >= 1 NPS). Patients with >= 4 NPS had more medical comorbidities and greater functional impairment (p <= 0.0001 for both). Patients with >= 4 NIPS were more likely than patients with 0-3 NPS to have amnestic MCI (81% vs 71%, respectively, p = 0.03), and patients with amnestic MCI were more likely than those with other subtypes to exhibit depressive symptoms. Patients with >= 4 NPS had nearly 2.5 times the odds of developing dementia at follow-up than patients with 0-3 NPS (adjusted O R= 2.44, 95% CI 1.07, 5.55).
Conclusion NPS are common in MCI patients. Those with an elevated number of NPS may be more likely to have the amnestic subtype of MCI, and depression may be more common in amnestic MCI than in other subtypes. An elevated number of NPS may increase risk of progression to dementia for patients with MCI. Copyright (C) 2009 John Wiley & Sons, Ltd.

AB Most serous adenocarcinomas involving both the endometrium and ovary are presumed to arise in the endometrium. Recently, serous tubal intraepithelial carcinoma (STIC) has been implicated in the pathogenesis of pelvic serous carcinoma. This study explored the potential relationship between STIC and uterine serous carcinoma. Twenty-two consecutive cases of serous carcinoma involving the endometrium were studied. In each case, fallopian tubes were submitted in toto according to the protocol for sectioning and extensive examination of the fimbriated end. Extent of the endometrial tumor and presence/absence of STIC were documented. Immunostaining for p53 and Wilms tLImor-1 was performed on all cases with STIC. p53 mutation analysis was performed in a subset of matched STICs and endometrial tumors. Eleven cases showed concurrent endometrial and adnexal involvement, including 6 with endosalpingeal involvement: STIC was confirmed in 5. In all 5, the concurrent endometrial tumor was either noninvasive, or exhibited only superficial (<5%) myometrial invasion. In 2 cases, identical p53 mutations were shared by both tubal and endometrial lesions. This Study shows that noninvasive, genetically related serous carcinomas may coexist in both tube and endometrium. As management of serous neoplasms is predicated on site of origin, we propose that the sectioning and extensively examining the fimbria protocol be applied to all endometrial serous carcinomas and that tumors with concurrent STIC be classified as a distinct subset of pelvic serous carcinomas pending a clearer understanding of tumor origin.

AB Background: In the general population, adiposity exhibits a J- or U-shaped relationship with mortality; however, in catabolic states this relationship is often inversely linear. We have recently documented an age-independent increase in overweight/obesity in the Pittsburgh Epidemiology of Diabetes Complications Study (EDC) of type 1 diabetes (T1D). As intensified insulin therapy (IIT) may promote weight gain, the impact of weight gain in T1D is of importance. We therefore assessed the association of adiposity with mortality in 655 EDC participants during 20 years of follow-up.
Methods: Individuals were categorized as underweight (body mass index (BMI) <20), normal (20 <= BMI <25), overweight (25 <= BMI <30), or obese (BMI >= 30). Cox models were constructed using BMI and covariates at baseline, updated means during follow-up, time variation (reflecting most recent status), and change during adulthood as predictors of mortality.
Results: The prevalence of IIT (3 + insulin shots daily and/or pump) increased from 7 to 82%. Overweight increased by 47% and obesity increased sevenfold. There were 146 deaths. In unadjusted models, BMI (modeled continuously) showed a quadratic relationship with mortality (P = 0.002, <0.0001 <0.0001 for baseline, updated mean and time-varying models, respectively). However, only in the time-varying model were the obese significantly different from the normal weight, whereas the baseline model showed no differences by BMI category. In both the updated mean and time-varying models, the underweight were at greater risk than were the normal weight (P<0.0001 both models). The nonlinear relationship of adiposity with mortality remained after adjustment for diabetes complications and for biological or socioeconomic/lifestyle risk factors, with the exception of baseline socioeconomic/lifestyle risk factors, in which a linear association emerged. Adjustment for waist circumference eliminated risk in the obese. Finally, weight gain during follow-up was protective.
Conclusion: The relationship of adiposity with mortality in T1D now seems to resemble that of the general population, albeit with a marked increased risk in those who are underweight. International Journal of Obesity (2009) 33, 796-805; doi:10.1038/ijo.2009.75; published online 19 May 2009

AB The tyrosine kinase receptor, HER2 is a crucial prognostic marker and therapeutic target for breast cancer; however, the downstream targets and biological effectors of HER2 remain unclear. We investigated the relationship between HER2 and the transcription factor FoxM1 in breast cancer. HER2 and FoxM1 expression levels were compared in breast carcinoma cell lines, paraffin-embedded breast cancer patient samples and at the mRNA level in purified breast epithelial cells. To further examine the relationship between HER2 and FoxM1 expression, we either overexpressed or siRNA-mediated depleted endogenous HER2 in breast cancer cell lines. Additionally, a mammary epithelium-targeted HER2 (neu) transgenic mouse model was also used to assess the effect of HER2 on FoxM1 levels. Furthermore, the effect of the HER2-tyrosine kinase inhibitor lapatinib on FoxM1 in HER2 positive breast cancer cells was investigated. HER2 protein levels directly correlated with FoxM1 expression in both breast carcinoma cell lines and paraffin-embedded breast cancer patient samples. Moreover, in purified breast epithelial cells, overexpression of HER2 was associated with high levels of FoxM1 mRNA, suggesting that the upregulation of FoxM1 expression is at least partially mediated transcriptionally. Furthermore, overexpression or ablation of endogenous HER2 resulted in parallel changes in FoxM1 expression. Critically, mammary epithelium-targeted HER2 mouse tumours also resulted in increased FoxM1 expression, Suggesting that HER2 directed FoxM1 expression occurs in. vivo and may be a critical downstream effector of HER2-targeting therapies. Indeed, treatment of breast cancer cells with lapatinib reduced FoxM1 expression at protein, mRNA and gene promoter levels. Moreover, analysis of normal and breast cancer patient samples revealed that elevated FoxM1 expression at protein and mRNA levels correlated with breast cancer development, but not significantly with cancer progression and survival. Our results indicate that the HER2 receptor regulates the expression of the FoxM1 transcription factor, which has a role in breast cancer development.

AB In addition to its immune suppressive function ill T-regulatory cells, the nuclear transcription factor, FOXP3, has been identified as a tumor suppressor. To evaluate the clinical efficacy of monoclonal antibody (mAb) 31310 Fv antibody-mediated FOXP3 protein therapy of cancer, the Fv-FOXP3 fusion protein produced in Pichia pastoris was tested on breast, ovarian, and colon cancer cells in vitro, and with colon cancer cells in vivo in a mouse model of colon cancer metastasis to liver. Treatment with Fv-FOXP3 resulted in dose-dependent cell death of cancer cells in vitro. Apoptosis was established as a mechanism of cell death by demonstrating increased production of the p17 activated fragment of caspase-3 by cancer cells in response to Fv-FOXP3 and inhibition of cell killing by the caspase inhibitor, Z-VAD-FMK. Fv-FOXP3 treatment resulted in clinically significant reduction in tumor burden in a syngeneic model of colon cancer metastasis to liver in Balb/c mice. These results represent the first demonstration of effective full-length FOXP3 protein therapy and emphasize the clinical potential of mAb 3E10 as an intracellular and intranuclear delivery vehicle of FOXP3 for prevention and treatment of cancer metastasis.

ID LARYNGOTRACHEAL RECONSTRUCTION; SUBGLOTTIC STENOSIS; REFLUX
AB Objectives: 1. Determine the feasibility of measuring tracheal pH with a novel non-aqueous probe designed for oropharyngeal pH monitoring. 2. Correlate clinical and subclinical laryngopharyngeal reflux aspiration events with esophageal pH measurements.
Methods: Five children with chronic indwelling tracheostomies undergoing routine endoscopy and pH probe monitoring at a tertiary care pediatric aerodigestive center between October 2007 and January 2008 were identified for this prospective feasibility pilot study. The non-aqueous Restech Dx-pH probe was subsequently affixed to each child's tracheostomy with the probe tip confirmed to be within the tracheal lumen. Esophageal and tracheal probe pH measurements were subsequently recorded until the child was unable to tolerate the study or 24 h elapsed. Tracheal pH tracings were compared directly to esophageal pH tracings. Esophageal biopsy and bronchoalveolar lavage data were reviewed for each child.
Results: 3/5 children tolerated the tracheal probe for greater than 18 h. Adequate tracheal pH tracings were demonstrated for all children while the probe was in position. Mean baseline tracheal pH was 7.8. One child demonstrated direct correlation between acidic esophageal reflux events and decreased tracheal pH. Esophageal biopsy confirmed the presence of active inflammation consistent with reflux in this child.
Conclusion: Tracheal pH can be accurately recorded with the Restech Dx-pH probe. The technology may allow further investigations to determine the impact of gastroesophageal refluxate aspiration and empiric antireflux therapy in children with aerodigestive symptoms.

AB The common factor that underlies several types of functional brain imaging is the electric current of masses of dendrites. The prodigious demands for the energy that is required to drive the dendritic currents are met by hemodynamic and metabolic responses that are visualized with fMRI and PET techniques. The high current densities in parallel dendritic shafts and the broad distributions of the loop currents outside the dendrites generate both the scalp EEG and the magnetic fields seen in the MEG. The measurements of image intensities and potential fields provide state variables for modeling. The relationships between the intensities of current density and the electric, magnetic, and hemodynamic state variables are complex and far from proportionate. The state variables are complementary, because the information they convey comes from differing albeit overlapping neural populations, so that efforts to cross-validate localization of neural activity relating to specified cognitive behaviors have not always been successful. We propose an alternative way to use the three methods in combination through studies of hemisphere-wide, high-resolution spatiotemporal patterns of neural activity recorded non-invasively and analyzed with multivariate statistics. Success in this proposed endeavor requires specification of what patterns to look for. At the present level of understanding, an appropriate pattern is any significant departure from random noise in the spectral, temporal and spatial domains that can be scaled into the coarse-graining of time by fMRI/BOLD and the coarse-graining of space by EEG and MEG. Here the requisite patterns are predicted to be large-scale spatial amplitude modulation (AM) of synchronized neuronal signals in the beta and gamma ranges that are coordinated but not correlated with fMRI intensities.

AB Purpose: Radiotherapy (XRT) for spine sarcomas is constrained by spinal cord, nerve, and viscera tolerance. Negative surgical margins are uncommon; hence, doses of >= 66 Gy are recommended. A Phase II clinical trial evaluated high-dose photon/proton XRT for spine sarcomas.
Methods and Materials: Eligible patients had nonmetastatic, thoracic, lumbar, and/or sacral spine/paraspinal sarcomas. Treatment included pre- and/or postoperative photon/proton XRT with or without radical resection; patients with osteosarcoma and Ewing's sarcoma received chemotherapy. Shrinking fields delivered 50.4 cobalt Gray equivalent (Gy RBE) to subclinical disease, 70.2 Gy RBE to microscopic disease in the tumor bed, and 77.4 Gy RBE to gross disease at 1.8 Gy RBE qd. Doses were reduced for radiosensitive histologies, concurrent chemoradiation, or when diabetes or autoimmune disease present. Spinal cord dose was limited to 63/54 Gy RBE to surface/center. Intraoperative boost doses of 7.5 to 10 Gy could be given by dural plaque.
Results: A total of 50 patients (29 chordoma, 14 chondrosarcoma, 7 other) underwent gross total (n = 25) or subtotal (n = 12) resection or biopsy (n = 13). With 48 month median follow-up, 5-year actuarial local control, recurrence-free survival, and overall survival are: 78%, 63%, and 87% respectively. Two of 36 (5.6%) patients treated for primary versus 7/14 (50%) for recurrent tumor developed local recurrence (p < 0.001). Five patients developed late radiation-associated complications; no myelopathy developed but three sacral neuropathies appeared after 77.12 to 77.4 Gy RBE.
Conclusions: Local control with this treatment is high in patients radiated at the time of primary presentation. Spinal cord dose constraints appear to be safe. Sacral nerves receiving 77.12-77.4 Gy RBE are at risk for late toxicity. (C) 2009 Elsevier Inc.

AB Purpose: To develop a Radiation Therapy Oncology Group (RTOG) atlas of the elective clinical target volume (CTV) definitions to be used for planning pelvic intensity-modulated radiotherapy (IMRT) for anal and rectal cancers.
Methods and Materials: The Gastrointestinal Committee of the RTOG established a task group (the nine physician co-authors) to develop this atlas. They responded to a questionnaire concerning three elective CTVs (CTVA: internal iliac, presacral, and perirectal nodal regions for both anal and rectal case planning; CTVB: external iliac nodal region for anal case planning and for selected rectal cases; CTVC: inguinal nodal region for anal case planning and for select rectal cases), and to outline these areas on individual computed tomographic images. The imaging files were shared via the Advanced Technology Consortium. A program developed by one of the co-authors (I.E.N.) used binomial maximum-likelihood estimates to generate a 95% group consensus contour. The computer-estimated consensus contours were then reviewed by the group and modified to provide a final contouring consensus atlas.
Results: The panel achieved consensus CTV definitions to be used as guidelines for the adjuvant therapy of rectal cancer and definitive therapy for anal cancer. The most important difference from similar atlases for gynecologic or genitourinary cancer is mesorectal coverage. Detailed target volume contouring guidelines and images are discussed.
Conclusion: This report serves as a template for the definition of the elective CTVs to be used in IMRT planning for anal and rectal cancers, as part of prospective RTOG trials. (C) 2009 Elsevier Inc.

AB Objectives: The objectives of this study were (i) to develop a systematic framework for describing and comparing different features of health technology assessment (HTA) agencies, (ii) to identify and describe similarities and differences between the agencies, and (iii) to draw conclusions both for producers and users of HTA in research, policy, and practice.
Methods: We performed a systematic literature search, added information from HTA agencies, and developed a conceptual framework comprising eight main domains: organization, scope, processes, methods, dissemination, decision, implementation, and impact. We grouped relevant items of these domains in an evidence table and chose five HTA agencies to test our framework: DAHTA@DIMDI, HAS, IQWiG, NICE, and SBU. Item and domain similarity was assessed using the percentage of identical characteristics in pairwise comparisons across agencies. Results were interpreted across agencies by demonstrating similarities and differences.
Results: Based on 306 included documents, we identified 90 characteristics of eight main domains appropriate for our framework. After applying the framework to the five agencies,we were able to show 40 percent similarities in "dissemination," 38 percent in "scope," 35 percent in "organization," 29 percent in "methods," 26 percent in "processes," 23 percent in "impact," 19 percent in "decision," and 17 percent in "implementation." Conclusion: We found considerably more differences than similarities of HTA features across agencies and countries. Our framework and comparison provides insights and clarification into the need for harmonization. Our findings could serve as descriptive database facilitating communication between producers and users.

AB PURPOSE. To develop and compare effective strategies for depleting graft-derived passenger leukocytes that include antigen-presenting cells from corneal buttons and to assess the effectiveness of this strategy in promoting graft survival using a high-risk (HR) model of corneal transplantation.
METHODS. Corneal buttons harvested from C57BL/6 mice were used in three ex vivo strategies of passenger leukocyte depletion. Two strategies involved storage in medium at different temperatures for prolonged periods. A third strategy used complement-dependent cytotoxicity (CDC) by treating the buttons with anti-CD45 mAb plus complement. Wholemount corneal buttons or cells from enzyme-digested corneas were analyzed using confocal microscopy or flow cytometry, respectively, for the pan-leukocyte surface marker CD45. HR host beds were created and used to evaluate the efficacy of passenger leukocyte depletion on transplant survival.
RESULTS. Passenger leukocyte numbers in the buttons were significantly reduced by all three treatments. CDC was the most efficient strategy for passenger leukocyte depletion with 39% reduction (P < 0.00005) of CD45(+) cells, and negligible damage to the endothelial layer, achievable within 24 hours. However, passenger leukocyte depletion failed to improve HR graft longevity.
CONCLUSIONS. Anti-CD45 antibody plus complement-mediated targeting of donor tissue is the most efficient way to deplete corneal passenger leukocytes and can considerably reduce the time required for cell depletion. However, depletion of graft passenger leukocytes does not have a significant effect on promoting graft survival even in the HR setting.

AB PURPOSE. To formulate and characterize a drug-eluting contact lens designed to provide extended, controlled release of a drug.
METHODS. Prototype contact lenses were created by coating PLGA (poly[lactic-co-glycolic acid]) films containing test compounds with pHEMA (poly[hydroxyethyl methacrylate]) by ultraviolet light polymerization. The films, containing encapsulated fluorescein or ciprofloxacin, were characterized by scanning electron microscopy. Release studies were conducted in phosphate-buffered saline at 37 degrees C with continuous shaking. Ciprofloxacin eluted from the contact lens was studied in an antimicrobial assay to verify antimicrobial effectiveness.
RESULTS. After a brief and minimal initial burst, the prototype contact lenses demonstrated controlled release of the molecules studied, with zero-order release kinetics under infinite sink conditions for over 4 weeks. The rate of drug release was controlled by changing either the ratio of drug to PLGA or the molecular mass of the PLGA used. Both the PLGA and the pHEMA affected release kinetics. Ciprofloxacin released from the contact lenses inhibited ciprofloxacin-sensitive Staphylococcus aureus at all time-points tested.
CONCLUSIONS. A prototype contact lens for sustained drug release consisting of a thin drug-PLGA film coated with pHEMA could be used as a platform for ocular drug delivery with widespread therapeutic applications. (Invest Ophthalmol Vis Sci. 2009;50:3346-3352) DOI:10.1167/iovs.08-2826

AB Objectives Our purpose was to evaluate percutaneous coronary intervention (PCI) attempt rates in patients with class I indications for coronary artery bypass graft (CABG) surgery after the introduction of drug-eluting stents (DES).
Background In patients with severe, multivessel coronary disease, CABG has historically been recommended over PCI. Practice guidelines for CABG were last updated before the emergence of data on DES efficacy.
Methods We analyzed 265,028 procedures from the NCDR (National Cardiovascular Data Registry) meeting American College of Cardiology/American Heart Association class I indications for surgical revascularization. Temporal trends in PCI attempt rates were analyzed during 3 consecutive time periods: pre-DES (before April 1, 2003), DES diffusion (April 1, 2003 to December 31, 2004), and DES (January 1, 2005 to September 30, 2006).
Results The attempted rate of PCI in patients with class I indications for CABG increased over the 3 time periods (pre-DES: 29.4%, DES diffusion: 33.4%, and DES era: 34.7%, p < 0.001). In a hierarchical multivariable logistic model adjusting for patient and PCI site characteristics, PCI attempts were more likely in the DES compared with pre-DES era (odds ratio: 1.44, 95% confidence interval: 1.40 to 1.48) and the DES diffusion era (odds ratio: 1.20, 95% confidence interval: 1.17 to 1.23). PCI attempt rates increased in all 3 time periods, although the average rate of increase during the DES era was 0.6% per quarter compared with 0.3% per quarter for both the DES diffusion and the pre-DES eras (p = 0.03).
Conclusions DES use in clinical practice was associated with a significant overall increase in PCI to treat patients with class I indications for CABG. Long-term follow-up of this cohort of patients is warranted. (J Am Coll Cardiol Intv 2009;2:614-21) (C) 2009 by the American College of Cardiology Foundation

AB Objective: To investigate whether elevated C-reactive protein (CRP) levels and HIV infection are independently associated with acute myocardial infarction (AMI) among patients receiving care in a large US health care system.
Methods: Analyses included patients receiving care in the Partners HealthCare System between January 1997 and December 2006, with a most recent CRP less than 3 years and more than 1 week before AMI. Over this period, 70,357 (487 HIV and 69,870 non-HIV) patients met these criteria, from the background population of 1,648,687 patients followed in the system. We included both CRP and high-sensitivity CRP and defined elevated CRP based on the normal range of the assay used. We used multivariate logistic regression analysis to test the association of elevated CRP and HIV with AMI after adjustment for demographic and other cardiovascular covariates, including hypertension, diabetes, and dyslipidemia.
Results: In univariate analyses, elevated CRP and HIV were each significantly associated with AMI [odds ratio (OR) 2.51; 95% confidence interval (CI) 2.27 to 2.78; P < 0.0001 for elevated CRP and OR 2.07; 95% CI 1.31 to 3.10; P = 0.001 for HIV]. In a combined model including CRP category and HIV status, elevated CRP (OR 2.50; 95% CI 2.26 to 2.77; P < 0.0001) and HIV (OR 1.74; 95% CI 1.10 to 2.61; P = 0.01) were both independently associated with AMI. In a fully adjusted model controlling for age, sex, race, hypertension, diabetes, and dyslipidemia, both elevated CRP (OR 2.13; 95% CI 1.92 to 2.37; P < 0.0001) and HIV (OR 1.93; 95% CI 1.21 to 2.93; P = 0.004) remained independently associated with AMI. Compared with patients with normal CRP and without HIV, the OR for AMI was increased more than 4-fold among patients with HIV and elevated CRP.
Conclusions: Elevated CRP and HIV are independently associated with increased AMI risk, and patients with HIV with increased CRP have a markedly increased relative risk of AMI. Measurement of CRP may be useful in the cardiovascular risk assessment of patients with HIV.

AB Background: Revised World Health Organization recommendations seek to increase HIV testing. We assessed the need for expanded testing in South Africa by examining current testing and treatment trends among a high prevalence population.
Methods: We determined the numbers of adults receiving HIV testing and antiretroviral treatment (ART) during 2001-2006 using testing registers linked to patient records from 2 health care facilities believed responsible for virtually all HIV services available to the population. We evaluated annual population testing rates using census population counts; proportions of clients testing seropositive (yield); CD4 counts and World Health Organization stage at diagnosis; and ART initiation rates.
Results: HIV testing rates rose from 4% in 2001 to 20% in 2006 (P < 0.001) and were highest among pregnant females receiving provider-initiated testing. Yield for first-time testers decreased from 47% in 2001 to 28% in 2006; annual incidence of seroconversion among initially HIV-negative. retesters was 1.9%. Median CD4 counts and World Health Organization stage distributions for newly diagnosed clients remained stable. HIV-infected clients receiving ART within 6 months of eligibility increased from 0% in 2001 to 68% in 2006 (P < 0.001).
Conclusions: Population testing and ART initiation rates rose dramatically during 2001-2006. Yet, yield remained high, and HIV-infected persons continued to receive late diagnoses. These findings highlight the continuing need for expanded testing and linkage to care.

AB Background: Previous studies have found high rates of childhood sexual abuse (CSA) among US men who have sex with men (MSM). CSA history has been associated with a variety of negative effects later in life including behaviors that place MSM at greater risk for HIV acquisition and transmission. The present analysis is the first to examine the longitudinal association between CSA and HIV infection, unprotected anal sex, and serodiscordant unprotected anal sex, as well as mediators of these relationships among a large sample of HIV-uninfected MSM.
Methods: The EXPLORE Study was a behavioral intervention trial conducted in 6 US cities over 48 months with HIV infection as the primary efficacy outcome. Behavioral assessments were done every 6 months via confidential computerized assessments. Longitudinal regression models were constructed, adjusting for randomization arm, geographical location of study site, age at enrollment, education, and race/ethnicity.
Results: Of the 4295 participants enrolled, 39.7% had a history of CSA. Participants with a history of CSA [adjusted hazards ratio = 1.30, 95% confidence interval (CI): 1.02 to 1.69] were at increased risk for HIV infection over study follow-up. A significant association was seen between history of CSA and unprotected anal sex (adjusted odds ratio = 1.24, 95% CI: 1.12 to 1.36) and serodiscordant unprotected anal sex (adjusted odds ratio = 1.30, 95% CI: 1.18 to 1.43). Among participants reporting CSA, the EXPLORE intervention had no effect in reducing HIV infection rates. Participants reporting CSA were significantly more likely to have symptoms of depression and use nonprescription drugs.
Conclusions: A predictive relationship between a history of CSA and subsequent HIV infection was observed among this large sample of HIV-uninfected MSM. Findings indicate that HIV-uninfected MSM with CSA histories are at greater risk for HIV infection, report higher rates of HIV sexual risk behavior, and may derive less benefit from prevention programs. Future HIV prevention interventions should address the specific mental health concerns of MSM with a history of CSA.

AB Context Prior studies have demonstrated conflicting results regarding how much information novel biomarkers add to cardiovascular risk assessment.
Objective To evaluate the utility of contemporary biomarkers for predicting cardiovascular risk when added to conventional risk factors.
Design, Setting, and Participants Cohort study of 5067 participants (mean age, 58 years; 60% women) without cardiovascular disease from Malmo, Sweden, who attended a baseline examination between 1991 and 1994. Participants underwent measurement of C-reactive protein (CRP), cystatin C, lipoprotein-associated phospholipase 2, midregional proadrenomedullin (MR-proADM), midregional proatrial natriuretic peptide, and N-terminal pro-B-type natriuretic peptide (N-BNP) and underwent follow-up until 2006 using the Swedish national hospital discharge and cause-of-death registers and the Stroke in Malmo register for first cardiovascular events (myocardial infarction, stroke, coronary death).
Main Outcome Measures Incident cardiovascular and coronary events.
Results During median follow-up of 12.8 years, there were 418 cardiovascular and 230 coronary events. Models with conventional risk factors had C statistics of 0.758 (95% confidence interval [CI], 0.734 to 0.781) and 0.760 (0.730 to 0.789) for cardiovascular and coronary events, respectively. Biomarkers retained in backward-elimination models were CRP and N-BNP for cardiovascular events and MR-proADM and N-BNP for coronary events, which increased the C statistic by 0.007 (P = .04) and 0.009 (P = .08), respectively. The proportion of participants reclassified was modest (8% for cardiovascular risk, 5% for coronary risk). Net reclassification improvement was nonsignificant for cardiovascular events (0.0%; 95% CI, -4.3% to 4.3%) and coronary events (4.7%; 95% CI, -0.76% to 10.1%). Greater improvements were observed in analyses restricted to intermediate-risk individuals (cardiovascular events: 7.4%; 95% CI, 0.7% to 14.1%; P = .03; coronary events: 14.6%; 95% CI, 5.0% to 24.2%; P = .003). However, correct reclassification was almost entirely confined to down-classification of individuals without events rather than up-classification of those with events.
Conclusions Selected biomarkers may be used to predict future cardiovascular events, but the gains over conventional risk factors are minimal. Risk classification improved in intermediate-risk individuals, mainly through the identification of those unlikely to develop events. JAMA. 2009;302(1):49-57

AB This paper reviews recent developments in high-resolution magnetic resonance imaging (MRI) and its application to image anatomy, physiology, and function in the retina of animals. It describes technical issues and solutions in performing retinal MRI, anatomical MRI, blood oxygenation level-dependent functional MRI (fMRI), and blood-flow MRI both of normal retinas and of retinal degeneration. MRI offers unique advantages over existing retinal imaging techniques, including the ability to image multiple layers without depth limitation and to provide multiple clinically relevant data in a single setting. Retinal MRI has the potential to complement existing retinal imaging techniques.

AB Purpose: To examine associations between depressive symptoms and dyad-level sexual risk behavior in young heterosexual dyads with sexually transmitted infection (STI).
Methods: Chlamydia-positive 14-24-year-old, heterosexually active outpatients and their opposite-sex partners completed an assessment that included demographics, past and recent STI risk behaviors, and the Beck Depression Inventory (BDI). Participants in the top 25% of BDI scores within gender were categorized as depressed. Variables were created to identify dyads in which the female or male partner was depressed, as well as a measure of concordance of depression between partners. Dyad-level STI risk variables were created from the STI risk characteristics reported by each dyad member, and associations between these and the depression variables were analyzed.
Results: The 130 dyads were comprised of young men and women at high STI risk. One-third of dyads had at least one depressed partner. Dyads in which the female partner was depressed had greater partner age difference, greater total number of lifetime partners, and one or more partners reporting substance use within 2 hours before sex, compared with dyads in which the female partner was not depressed. Dyads in which the male partner was depressed were more likely than the nondepressed-male dyads to report substance use before sex. All dyads in which both partners were depressed reported substance use before sex.
Conclusions: In young, chlamydia-infected, heterosexual dyads, depressive symptoms, especially in women, is related to increased dyad-level STI risk, including greater partner age difference, more partners, and substance use before sex. (c) 2009 Society for Adolescent Medicine. All rights reserved.

AB Objectives: The objective of this study was to investigate the effect of acupuncture administered during myelosuppressive chemotherapy on white blood cell (WBC) count and absolute neutrophil count (ANC) in patients with ovarian cancer.
Design: This study is a pilot, randomized, sham-controlled clinical trial. Patients received active acupuncture versus sham acupuncture while undergoing chemotherapy. A standardized acupuncture protocol was employed with manual and electrostimulation. The frequency of treatment was 2-3 times per week for a total of 10 sessions, starting 1 week before the second cycle of chemotherapy.
Setting: The setting was two outpatient academic centers for patients with cancer.
Subjects: Twenty-one (21) newly diagnosed and recurrent ovarian cancer patients were the subjects.
Outcome measures: WBC count, ANC, and plasma granulocyte colony-stimulating factor (G-CSF) were assessed weekly.
Results: The median leukocyte value in the acupuncture arm at the first day of the third cycle of chemotherapy was significantly higher than in the control arm after adjusting for baseline value (8600 cells/mu L, range: 4800 12,000 versus 4400 cell/mu L, range: 2300-10,000) (p=0.046). The incidence of grade 2-4 leukopenia was less in the acupuncture arm than in the sham arm (30% versus 90%; p=0.02). However, the median leukocyte nadir, neutrophil nadir, and recovering ANC were all higher but not statistically significantly different (p=0.116-0.16), after adjusting for baseline differences. There were no statistically significant differences in plasma G-CSF between the two groups.
Conclusions: We observed clinically relevant trends of higher WBC values during one cycle of chemotherapy in patients with ovarian cancer, which suggests a potential myeloprotective effect of acupuncture. A larger trial is warranted to more definitively determine the efficacy of acupuncture on clinically important outcomes of chemotherapy-induced neutropenia.

AB Our objective was to investigate the genitourinary defects and fertility of the male lysyl oxidase-like 1 gene (Loxl1) knockout (Loxl1(-/-)) mouse, with particular attention to fecundity and testicular, epididymal, gubernacular, and penile histopathology, which may lead us to a better understanding of the role of the elastin-homeostasis gene, LOXL1, in male sexual development. Genital morphometric evaluation of 6- to 9-month-old male Loxl1(-/-) mice (n = 26) was compared with C57BI/6 controls (n = 24). Measurements included: body weight, scrotal development, evidence of feminization (nipples or vaginal pouch), penile malformations, anogenital distance, and absence/presence and size of perineal bulge. Sperm production was estimated using a standardized technique. A breeding program was conducted to determine how much of the infertility observed in Loxl(1-/-) pairs was due to the male factor. Finally, we performed histopathologic comparison of the genitourinary organs of Loxl1(-/-) and control mice. Loxl1(-/-) mice weighed less than their age-matched C57BI/6 counterparts (P < .001). Size-adjusted perineal bulge was larger (P <.001), and resting location of the gonads was higher intra-abdominally (P = .048) in the Loxl1(-/-) mice. Estimates of daily sperm counts revealed that the Loxl1(-/-) mice had lower sperm production (P = .048). Loxl1(-/-) males bred with control females demonstrated relative fecundity values intermediate between Loxl1(-/-) pairs (lowest fecundity) and control pairs (highest fecundity), suggesting a component of male-factor infertility. No histologic differences were noted using hematoxylin-eosin or specialized elastin staining of the gonads, gubernaculum, and penis. Although further studies are warranted, these findings suggest a subtle and likely multifactorial role of the LOXL1 protein in male sexual development and fertility.

AB Objectives: The emergence of less common, but clinically important, fungal pathogens including the rare yeasts has contributed to the substantial morbidity and mortality observed in immunocompromised patients. These organisms can be resistant or refractory to existing antifungal agents. We sought to evaluate the activity of the new triazole isavuconazole against these difficult pathogens.
Methods: MICs of isavuconazole, voriconazole, posaconazole, fluconazole, amphotericin B and flucytosine were determined for 54 Trichosporon, 7 Geotrichum capitatum, 18 Saccharomyces cerevisiae, 11 Pichia and 14 Rhodotorula species in accordance with the M27-A2 reference method. Minimum fungicidal concentrations were also measured for each agent.
Results: Isavuconazole demonstrated excellent in vitro activity against each species tested. MIC(90) values ranged between 0.125 and 0.25 mg/L against Trichosporon isolates, and between 0.03 and 0.5 mg/L against the other yeast tested. The geometric mean MICs of isavuconazole were similar to those of voriconazole and similar or less than those of posaconazole, fluconazole, amphotericin B and flucytosine for all species tested. This activity was also maintained against one Trichosporon asahii and nine Rhodotorula isolates that were resistant to fluconazole.
Conclusions: Isavuconazole is a welcome addition to the growing antifungal armamentarium with potent in vitro activity against emerging yeast pathogens. Although this agent may be useful in the treatment of the rare yeasts, clinical data are needed to verify these results.

AB Objectives: The objectives of this study were to examine: (i) synergy of the combination of triclosan and DispersinB (R) (DspB); (ii) in vitro efficacy and durability of triclosan + DspB-coated vascular catheters; and (iii) in vivo efficacy of triclosan + DspB-coated catheters compared with chlorhexidine-silver sulfadiazine (CH-SS)-coated and uncoated (control) vascular catheters in preventing colonization by Staphylococcus aureus.
Methods: We investigated the potential synergistic antimicrobial and antibiofilm activity of triclosan and DspB by biofilm assays. The in vitro antimicrobial efficacy of triclosan + DspB-coated catheters was determined by microbial colonization assays. Antimicrobial durability of the coated catheters was tested by soaking segments in bovine serum for 7 days and determining antimicrobial activity, and by a serial plate transfer method. The in vivo efficacy of triclosan + DspB-coated catheters compared with CH-SS-coated and uncoated catheters was assessed by subcutaneous implantation of segments in a rabbit model of S. aureus infection.
Results: The combination of triclosan and DspB showed synergistic antimicrobial and antibiofilm activity against S. aureus, Staphylococcus epidermidis and Escherichia coli, significantly reduced bacterial colonization (P<0.05) and generally demonstrated a prolonged superior antimicrobial activity against clinical pathogens compared with CH-SS-coated catheters. Triclosan + DspB-coated and CH-SS-coated catheters exhibited equal in vivo efficacy (P <= 0.05) in reducing colonization by S. aureus compared with uncoated catheters.
Conclusions: Catheters coated with the triclosan + DspB combination showed synergistic, broad-spectrum and durable antimicrobial activity. Furthermore, the in vivo efficacy of catheters coated with this unique antimicrobial/antibiofilm composition prompts clinical evaluation of such an innovative approach.

J Appl Physiol 107: 266-274, 2009. First published May 14, 2009; doi:10.1152/japplphysiol.91386.2008.-The effect of body posture on regional ventilation during bronchoconstriction is unknown. In five subjects with asthma, we measured spirometry, low-frequency (0.15Hz) lung elastance, and resistance and regional ventilation by intravenous (13)NN-saline positron emission tomography before and after nebulized methacholine. The subjects were imaged prone on 1 day and supine on another, but on both days the methacholine was delivered while prone. From the residual (13)NN after washout, ventilation defective areas were defined, and their location, volume, ventilation, and fractional gas content relative to the rest of the lung were calculated. Independent of posture, all subjects developed ventilation defective areas. Although ventilation within these areas was similarly reduced in both postures, their volume was smaller in prone than supine (25 vs. 41%, P < 0.05). The geometric center of the ventilation defective areas was gravitationally dependent relative to that of the lung in both postures. Mean lung fractional gas content was greater in the prone position before methacholine and did not increase as much as in the supine position after methacholine. In the prone position at baseline, areas that became ventilation defects had lower gas content than the rest of the lung. In both positions at baseline, there was a gradient of gas content in the vertical direction. In asthma, the size and location of ventilation defects is affected by body position and likely affected by small differences in lung expansion during bronchoconstriction.

AB We investigated linguistic and visuospatial processing during pictorial reasoning in high-functioning autism (HFA), Asperger's syndrome (ASP), and age and IQ-matched typically developing participants (CTRL), using three conditions designed to differentially engage linguistic mediation or visuospatial processing (visuospatial, V; semantic, S; visuospatial + semantic, V + S). The three groups did not differ in accuracy, but showed different response time profiles. ASP and CTRL participants were fastest on V + S, amenable to both linguistic and nonlinguistic mediation, whereas HFA participants were equally fast on V and V + S, where visuospatial strategies were available, and slowest on S. HFA participants appeared to favor visuospatial over linguistic mediation. The results support the use of linguistic versus visuospatial tasks for characterizing subtypes on the autism spectrum.

AB This study assessed factors associated with extended length of stay (ELOS) for patients presenting to a psychiatric emergency service (PES). Two hundred six subjects with a length of stay of 24 h or longer were compared with time-matched controls (patients that presented directly after the ELOS patient). Binary logistic regression was used to identify risk factors for ELOS. ELOS was associated with suicidal ideation, disposition to an inpatient unit, homicidal ideation, lack of insurance, homelessness, male gender, past history of psychiatric hospitalization, diagnosis of substance abuse, significant psychiatric co-morbidity (represented by three or more Axis I diagnoses), and diagnosis of a psychotic disorder. Lack of insurance, suicidal ideation, disposition to inpatient unit, and homicidal ideation all made nonredundant contributions to predicting stays of 24 h or longer.

AB To analyse the binding of sugar chains to proteins, viruses and cells, the surface plasmon resonance (SPR) technique is very convenient and effective because it is a real-time, non-destructive detection system. Key to this method is linker compounds for immobilization of the sugar chains to the gold-coated chip for SPR. Also, well-designed fluorescent labelling reagents are essential when analysing the structure of trace amounts of sugar chains derived from natural sources, such as glycoproteins on the surface of specific cells. In this report, we developed a novel linker molecule, named 'f-mono', which has both of these properties: simple immobilization chemistry and a fluorescent label. Since the molecule contains a 2,5-diaminopyridyl group and a thioctic acid group, conjugation with sugar chains can be achieved using the well-established reductive amination reaction. This conjugate of sugar chain and fluorescent linker (fluorescent ligand-conjugate, FLC) has fluorescent properties (ex. 335 nm, em. 380 nm), and as little as 1 mu g of FLC can be easily purified using HPLC with a fluorescent detector. MS and MS/MS analysis of the FLC is also possible. As a +2 Da larger MS peak ([M + H + 2](+) ion) was always associated with the theoretical MS peak ([M + H](+)) (due to the reduction of the thioctic acid moiety), the MS peaks of the FLC were easily found, even using unfractionated crude samples. Immobilization of the FLC onto gold-coated chips, and their subsequent SPR analyses were successively accomplished, as had been performed previously using non-fluorescent ligand conjugates.

AB The heat shock (HS) response is a protective mechanism for cells to protect themselves against subsequent lethal stress. HS upregulated heat shock protein (HSP) expression reduced apoptosis following tumor necrosis factor-alpha (TNF-alpha) stimulation. However, vector-mediated overexpression of HSP70 failed to provide similar protection but rather sensitized cells to TNF-alpha induced apoptosis. This may be due to the fact that the kinetics of vector-mediated HSP overexpression is totally different from that of HSP upregulation by HS. We hypothesized that the response depends on the timing of TNF-alpha challenge relative to HSP expression dynamics after HS. Therefore, we investigated the correlation between the dynamic change of HSP expression and the levels of apoptosis induced by TNF-alpha after HS. Hepatoma cells were subjected to mild heat shock at 42 degrees C for 2 h followed by varied recovery times and then treated with TNF-alpha to induce apoptosis. The results from quantitative apoptosis assays using the TUNEL reaction reveal an optimal HS protection window centered around 5 h post-HS against TNF-alpha induced apoptosis. In addition, we found a window extending up to 2 h after HS where HS sensitized cells to TNF-alpha stress. Importantly, the correlation between apoptosis and HSP expression kinetics demonstrates that both high levels of HSPs and proper timing between HS and TNF-alpha stress were critical for optimal protection. Our study establishes a dynamic experimental model for further investigation of HS as a potential clinical approach to target tissue survival or death. [DOI: 10.1115/1.3118768]

AB The relationship between measurements of cerebral blood oxygenation and neuronal activity is highly complex and depends on both neurovascular and neurometabolic biological coupling. While measurements of blood oxygenation changes via optical and MRI techniques have been developed to map functional brain activity, there is evidence that the specific characteristics of these signals are sensitive to the underlying vascular physiology and structure of the brain. Since baseline blood flow and oxygen saturation may vary between sessions and across subjects, functional blood oxygenation changes may be a less reliable indicator of brain activity in comparison to blood flow and metabolic changes. In this work, we use a biomechanical model to examine the relationships between neural, vascular, metabolic, and hemodynamic responses to parametric whisker stimulation under both normal and hypercapnic conditions in a rat model. We find that the relationship between neural activity and oxy- and deoxyhemoglobin changes is sensitive to hypercapnia-induced changes in baseline cerebral blood flow. In contrast, the underlying relationships between evoked neural activity, blood flow, and model-estimated oxygen metabolism changes are unchanged by the hypercapnic challenge. We conclude that evoked changes in blood flow and cerebral oxygen metabolism are more closely associated with underlying evoked neuronal responses.

AB Cbl proteins are multifunctional adaptor molecules that modulate cellular activity by targeting the ubiquitylating system, endocytic complexes, and other effectors to a wide variety of regulatory proteins, especially activated receptor and nonreceptor tyrosine kinases. Cbl and Cbl-b perform unique functions in various cells, in addition to redundant functions that are required for embryonic development. We previously showed that eliminating Cbl impaired osteoclast motility, which modestly delayed embryonic bone development. We now report that Cbl-b(-/-) mice are osteopenic, because of increased bone resorption with little compensating increase in bone formation. In vitro bone-resorbing activity and differentiation of osteoclast-like cells (OCLs) were increased, as were some RANKL-induced signaling events (activation of NF-kappa B and the mitogen-activated protein kinases extracellular signal-regulated kinase [ERK] and p38), suggesting that specific RANKL-activated mechanisms contribute to the increased rate of differentiation and bone-resorbing activity. Re-expressing Cbl-b in Cbl-b(-/-) OCLs normalized the increased bone-resorbing activity and overexpressing Cbl-b in wildtype OCLs inhibited bone resorption. Cbl was without effect in either wildlype or Cbl-b(-/-) OCLs. Functional tyrosine kinase binding (TKB) and RING finger domains were required for the rescue by Cbl-b. Thus, both Cbl and Cbl-b perform regulatory functions in osteoclasts that are unique to one or the other protein (i.e., functions that cannot be compensated by the other homolog). One of Cbl-b's unique functions in osteoclasts is to downregulate bone resorption. J Bone Miner Res 2009;24:1162-1172. Published online on February 16, 2009; doi: 10.1359/JBMR.090205

AB PURPOSE: Although cardiac rehabilitation programs have been shown to decrease cardiovascular risk, morbidity, and mortality, few programs have integrated a balanced mind/body approach in which patients are taught the relaxation response and utilize cognitive behavior skills for stress management, along with diet and exercise. We examined the medical and psychological outcomes of patients treated in such a cardiac rehabilitation program in a general hospital setting.
METHODS: From 1997 to 2005, outcomes were measured in 637 patients with coronary artery disease at baseline and after a 3-month program. Components of the intervention included smoking cessation, moderate aerobic exercise, nutrition counseling, relaxation response training, and cognitive/behavioral skills.
RESULTS: Men and women improved significantly with respect to medical outcomes (blood pressure, lipids, weight, exercise conditioning, frequency of symptoms of chest pain and shortness of breath) and psychological outcomes (general severity index, depression, anxiety, and hostility) (P<.0001). Patients considered "at higher risk" for cardiac events due to high baseline measures improved their measures to a less than "at higher risk" level. Data indicate that specific components of the intervention, that is, increased relaxation response practice and exercise, significantly contributed to these improvements (P<.05). Furthermore, age and gender differences, particularly for psychological measures, were found; younger patients and female patients had greater improvements than older patients and male patients.
CONCLUSIONS: This study provides preliminary data for a subsequent randomized control trial to test mind/body-based interventions to determine the most effective outcomes at an affordable cost.

AB Cellular repressor of E1A-stimulated genes (CREG) is a secreted glycoprotein of 220 amino acids. It has been proposed that CREG acts as a ligand that enhances differentiation and/or reduces cell proliferation. CREG has been shown previously to attenuate cardiac hypertrophy in vitro. However, such a role has not been determined in vivo. In the present study, we tested the hypothesis that overexpression of CREG in the murine heart would protect against cardiac hypertrophy and fibrosis in vivo. The effects of constitutive human CREG expression on cardiac hypertrophy were investigated using both in vitro and in vivo models. Cardiac hypertrophy was produced by aortic banding and infusion of angiotensin II in CREG transgenic mice and control animals. The extent of cardiac hypertrophy was quantitated by two-dimensional and M-mode echocardiography as well as by molecular and pathological analyses of heart samples. Constitutive over-expression of human CREG in the murine heart attenuated the hypertrophic response, markedly reduced inflammation. Cardiac function was also preserved in hearts with increased CREG levels in response to hypertrophic stimuli. These beneficial effects were associated with attenuation of the mitogen-activated protein kinase (MAPK)-extracellular signal-regulated kinase 1 (MEK-ERK1)/2-dependent signalling cascade. In addition, CREG expression blocked fibrosis and collagen synthesis through blocking MEK-ERK1/2-dependent Smad 2/3 activation in vitro and in vivo. Therefore, the expression of CREG improves cardiac functions and inhibits cardiac hypertrophy, inflammation and fibrosis through blocking MEK-ERK1/2-dependent signalling.

AB Context: The mechanism of IGF2 overexpression in non-islet-cell tumor hypoglycemia is not understood.
Objective: We investigated the imprinting control and promoter usage for IGF2 expression to identify a mechanism for increased IGF-II production in non-islet-cell tumor hypoglycemia.
Patient and Methods: A patient with metastatic hemangiopericytoma was studied. Tissue from the original hemangiopericytoma, metastatic tumor, and uninvolved liver was analyzed for IGF-II immunohistochemistry. IGF2, a paternally imprinted gene, shares a control region with maternally imprinted H19, a putative tumor suppressor. IGF-II and H19 mRNA expression was compared in metastatic tumor and uninvolved liver by quantitative RT-PCR. Imprinting of IGF2/H19 genes and IGF2 promoter usage in metastatic tumor was investigated by RT-PCR and sequence analysis, and the methylation pattern in the IGF2/H19 imprinting control region was analyzed.
Results: IGF-II protein expression was increased in metastatic tumor vs. uninvolved liver and original tumor. In the metastatic tumor, IGF-II mRNA was increased 60-fold, but H19 mRNA was comparable to uninvolved liver; loss of imprinting of IGF2, but not H19, was identified; no major change in methylation of the IGF2/H19 imprinting control regions was observed; and transcripts from four different IGF2 promoters were detected, compared to two in uninvolved liver.
Conclusions: IGF-2 overexpression, newly acquired in the metastatic tumor, was associated with loss of IGF2 gene imprinting and different promoter usage. The imprinting control mechanism governing the IGF2/H19 locus was intact, as evidenced by normal levels of H19, maintenance of H19 imprinting, and no major change in methylation of the imprinting control regions.

AB Context: Both GH deficiency (GHD) and GH excess are associated with a decreased quality of life. However, it is unknown whether patients with GHD after treatment for acromegaly have a poorer quality of life than those with normal GH levels after cure of acromegaly.
Objective: The aim of the study was to determine whether patients with GHD and prior acromegaly have a poorer quality of life than those with GH sufficiency after cure of acromegaly.
Design and Setting: We conducted a cross-sectional study in a General Clinical Research Center.
Study Participants: Forty-five patients with prior acromegaly participated: 26 with GHD and 19 with GH sufficiency.
Intervention: There were no interventions.
Main Outcome Measures: We evaluated quality of life, as measured by 1) the Quality of Life Adult Growth Hormone Deficiency Assessment (QoL-AGHDA); 2) the Short-Form Health Survey (SF-36); and 3) the Symptom Questionnaire.
Results: Mean scores on all subscales of all questionnaires, except for the anger/hostility and anxiety subscales of the Symptom Questionnaire, showed significantly impaired quality of life in the GH-deficient group compared with the GH-sufficient group. Peak GH levels after GHRH-arginine stimulation levels were inversely associated with QoL-AGHDA scale scores (R = -0.53; P = 0.0005) and the Symptom Questionnaire Depression subscale scores (R = -0.35; P = 0.031) and positively associated with most SF-36 subscale scores.
Conclusions: Our data are the first to demonstrate a reduced quality of life in patients who develop GHD after cure of acromegaly compared to those who are GH sufficient. Further studies are warranted to determine whether GH replacement would improve quality of life for patients with GHD after cure from acromegaly. (J Clin Endocrinol Metab 94: 2471-2477, 2009)

AB Context: The stimulatory effect of teriparatide on bone mineral density (BMD) and bone turnover is initially exuberant, but then diminishes.
Objective: Our objective was to determine whether retreating with teriparatide after a drug-free period can restore the initial exuberant response to teriparatide.
Design and Setting: This was a planned extension of a randomized controlled trial conducted in a single university hospital.
Patients and Intervention: Subjects previously participated in a 30-month randomized trial comparing the effects of alendronate (group 1), teriparatide (group 2), or both (group 3) on BMD and bone turnover in men and women with low BMD (phase 1). Subjects who completed phase 1 on their assigned therapy entered phase 2 (months 30-42), during which teriparatide was stopped in groups 2 and 3. Teriparatide was administered to all subjects during months 42 to 54 (phase 3).
Main Outcome Measures: We compared changes in BMD and markers of bone turnover (serum osteocalcin, N-terminal propeptide of type 1 collagen, and N-telopeptide) between phase 1 and 3 in subjects receiving teriparatide alone.
Results: Posterior-anterior and lateral spine BMD increased 12.5 +/- 1.5 and 16.9 +/- 1.7%, respectively, during the first 12 months of teriparatide administration and 5.2 +/- 0.8 and 6.2 +/- 1.8%, respectively, during teriparatide retreatment (P < 0.001 and P = 0.001). Increases in osteocalcin (P < 0.001), N-terminal propeptide of type 1 collagen (P < 0.001), and N-telopeptide (P < 0.001) were greater during the first period of teriparatide administration.
Conclusion: The response to teriparatide is attenuated when readministered after a 12-month hiatus. (J Clin Endocrinol Metab 94: 2495-2501, 2009)

AB This longitudinal study evaluated the response to periodontal treatment by subjects infected with either JP2 (n = 25) or non-JP2 (n = 25) Aggregatibacter (Actinobacillus) actinomycetemcomitans. Participants were treated during the first 4 months by receiving (i) scaling and root planing, (ii) systemic antibiotic therapy, and (iii) periodontal surgery. Probing depth (PD), clinical attachment level (CAL), and gingival and plaque indices (GI and PI, respectively) were monitored at baseline and at 12 months, along with DNA-PCR-based subgingival detection of JP2 or non-JP2 A. actinomycetemcomitans. At baseline, PD, CAL, and GI scores were statistically higher in the JP2 strain-positive group than the non-JP2-strain-positive group. At 12 months, PD, CAL, and GI scores had decreased significantly for both groups, but the reduction rates of PD and CAL were higher in the non-JP2-strain-positive group. Among JP2-strain-positive patients in the baseline, patients who remained JP2 strain positive at 12 months showed significantly higher GIs than did the patients who had lost the detectable JP2 clone. Patients who remained JP2 strain positive at 12 months appeared to be more resistant to mechanical-chemical therapy than did those who were still non-JP2 strain positive, while the elimination of JP2 A. actinomycetemcomitans remarkably diminished gingival inflammation. Early identification and elimination of the JP2 clone of A. actinomycetemcomitans will enable practitioners to effectively predict the outcome of treatments applied to periodontal patients.

AB Purpose
To study the pharmacokinetics (PK) of imatinib (IM) in patients with advanced GI stromal tumors (GISTs) treated in a randomized phase II study and to explore the potential relationship between IM plasma levels and long-term clinical outcomes.
Patients and Methods
Patients were randomly assigned to receive IM at 400 mg versus 600 mg daily. IM plasma levels were analyzed in a subset of patients (n = 73) for whom PK data on day 1 and at steady-state (SS, day 29) were available. IM PK was evaluated using a population PK approach. The relationship between IM plasma exposure and clinical outcome was explored by grouping patients into quartiles according to IM trough concentration (C(min)). The clinical outcome parameters evaluated include overall objective benefit rate (OOBR; complete response plus partial response plus stable disease) time to progression (TTP), and KIT genotyping.
Results
IM PK exposure showed a high inter-patient variability, and clinical outcomes were correlated with IM trough levels at SS. The median TTP was 11.3 months for patients in the lowest C(min) quartile (Q1, < 1,110 ng/mL) compared with more than 30 months for Q2 to Q4 (P = .0029). OOBR was also inferior in Q1 patients. In patients with GIST with KIT exon 11 mutations (n = 39), the OOBR was 67% for Q1 patients versus 100% for all others (P = .001).
Conclusion
In patients with advanced GIST, IM trough levels at SS were associated with clinical benefit. Patients with IM C(min) below 1,100 ng/mL showed a shorter TTP and lower rate of clinical benefit (OOBR). Further studies are justified to test whether monitoring IM plasma levels might optimize clinical outcomes for patients with GIST.

AB Purpose
To evaluate the potential benefit of continuous daily dosing sunitinib in patients with advanced nongastrointestinal stromal tumor (GIST) sarcomas.
Patients and Methods
A total of 53 patients with advanced non-GIST soft tissue sarcomas received sunitinib 37.5 mg daily. Primary end point was Response Evaluation Criteria in Solid Tumors defined response. Secondary end points were stable disease at 16 and 24 weeks. [(18)F]-fluorodeoxyglucose positron emission tomography was performed on a subset of 24 patients at baseline and after 10 to 14 days of therapy.
Results
Forty-eight patients were eligible for response. One patient (desmoplastic round cell tumor [DSRCT]) achieved a confirmed partial response (PR) and remained on study for 56 weeks. Ten patients (20%) achieved stable disease for at least 16 weeks. Metabolic PR was seen in 10 (47%) of 21 of patients. Metabolic stable disease was seen in 11 (52%) of 21. There were no unexpected toxicities observed.
Conclusion
Sunitinib demonstrated notable evidence of metabolic response in several patients with non-GIST sarcoma. The relevance of disease control observed in subtypes with an indolent natural history is unknown, however, the durable disease control observed in DSRCT, solitary fibrous tumor, and giant cell tumor of bone suggests that future evaluation of sunitinib in these subtypes may be warranted.

AB Purpose To update the 2002 American Society of Clinical Oncology guideline on pharmacologic interventions for breast cancer (BC) risk reduction.
Methods A literature search identified relevant randomized trials published since 2002. Primary outcome of interest was BC incidence (invasive and noninvasive). Secondary outcomes included BC mortality, adverse events, and net health benefits. An expert panel reviewed the literature and developed updated consensus guidelines.
Results Seventeen articles met inclusion criteria. In premenopausal women, tamoxifen for 5 years reduces the risk of BC for at least 10 years, particularly estrogen receptor (ER)-positive invasive tumors. Women <= 50 years of age experience fewer serious side effects. Vascular and vasomotor events do not persist post-treatment across all ages. In postmenopausal women, raloxifene and tamoxifen reduce the risk of ER-positive invasive BC with equal efficacy. Raloxifene is associated with a lower risk of thromboembolic disease, benign uterine conditions, and cataracts than tamoxifen in postmenopausal women. No evidence exists establishing whether a reduction in BC risk from either agent translates into reduced BC mortality.
Recommendations In women at increased risk for BC, tamoxifen (20 mg/d for 5 years) may be offered to reduce the risk of invasive ER-positive BC, with benefits for at least 10 years. In postmenopausal women, raloxifene (60 mg/d for 5 years) may also be considered. Use of aromatase inhibitors, fenretinide, or other selective estrogen receptor modulators to lower BC risk is not recommended outside of a clinical trial. Discussion of risks and benefits of preventive agents by health providers is critical to patient decision making. J Clin Oncol 27: 3235-3258. (C) 2009 by American Society of Clinical Oncology

AB Propofol pharmacokinetics were examined in 17 adults with major burns during the hyperdynamic convalescent phase. Eighteen nonburned surgical patients served as controls. After a 2-mg/kg intravenous dose of propofol, blood samples were collected at multiple time points. Noncompartmental methods were used to calculate the pharmacokinetic parameters. The following indices were higher in burns than controls: propofol clearance (64 +/- 17 vs 29 +/- 4 mL/kg/min, P < .001) and volume of distribution (8 +/- 3 vs 4 +/- 1 L/kg, P < .001). The area under the curve was smaller in burns (556 +/- 152 vs 1193 +/- 183 mu g/mL h, P < .001). The higher clearance of propofol in burned patients may imply that these patients require higher doses or infusion rates of propofol to attain a target plasma concentration or pharmacodynamic effect.

AB Objective: Hypogonadism and subthreshold depression are common conditions in elderly men. The objective of this study was to examine the effect of testosterone treatment in older, hypogonadal men with subthreshold depression.
Method: A randomized, double-blind, placebo-controlled study was conducted at a university-affiliated Veterans Affairs Medical Center among men aged 50 years or older (N = 33) with screening total testosterone levels of <= 280 ng/dL and subthreshold depression (dysthymia or minor depression, according to DSM-IV). Recruitment for the study was conducted from November 2002 through May 2005. Participants received either 7.5 g of testosterone gel or placebo gel daily for 12 weeks, followed by a 12-week open-label extension phase during which all subjects received 7.5 g of testosterone gel. The primary outcome measure was the change in the Hamilton Rating Scale for Depression (HAM-D) score from baseline to the end of the double-blind phase. Secondary outcome measures were remission of subthreshold depression (defined a priori as a HAM-D score <= 7) and changes in the Hopkins Symptom Checklist depression scale, the Medical Outcomes Study 36-Item Short-Form Health Survey, and the short-form 16-item Quality of Life Enjoyment and Satisfaction Questionnaire.
Results: At the end of the double-blind phase, testosterone-treated men had a greater reduction in HAM-D scores (p = .024) and a higher remission rate of subthreshold depression (52.9% vs. 18.8%, p = .041) than did placebo-treated men, but there were no differences in other secondary outcome measures between groups. At the end of the open-label phase, the testosterone group had sustained improvement, the control group improved, and there were no differences between groups in any outcome measures.
Conclusion: These results suggest that testosterone replacement may be efficacious treatment for subthreshold depression in older men with hypogonadism. Larger studies are needed to corroborate these findings.

AB Background: List-learning tasks are frequently used to provide measures of "executive functions'' that are believed necessary for successful memory performance. Small sample sizes, confounding anomia, and incomplete representation of all frontal regions have prevented consistent demonstration of distinct regional frontal effects on this task. Objective: To confirm specific effects of lesions in different frontal regions. Subjects: Forty-one patients with chronic focal frontal lesions and 38 control subjects. There were no group differences in naming scores. Methods: Two word lists were presented, one with unblocked words from related categories and one in a preblocked format. Standard measures of learning, recall, recognition, and strategies were obtained, first for the frontal group as a whole and then for large but defined frontal regions. For all measures with significant group differences, a lesion "hotspotting'' method identified possible specific regional injury effects. Results: The frontal group was impaired on almost all measures, but impairments on most measures were particularly identified with lesions in the left superior frontal lobe (approximately area 9s) and some deficits in learning processes were surprisingly more prominent on the blocked list. Conclusion: Difficulty with list learning is not a general property of all frontal lesions. Lesions in different frontal regions impair list learning through specific mechanisms, and these effects may be modified by manipulations of the task structure.

Results: The blood flow (BF), blood volume (BV), and permeability surface were significantly higher, and the mean transit time was significantly lower in the tumor than in the normal tissue. The tumor BF and BV significantly decreased, and the mean transit time significantly increased after the therapy; decrease in B F and BV correlated with tumor volume reduction after chemotherapy. The baseline tumor BV was significantly lower in nonresponders compared with that in responders.
Conclusions: In patients with SCCA, CTp showed potential for monitoring induction chemotherapy, reduction in tumor BF and BV correlated with reduction of turner volume after chemotherapy, and baseline tumor BV may predict response to chemotherapy.

AB Activin was discovered in the 1980s as a gonadal protein that stimulated FSH release front pituitary gonadotropes and was thought of as a reproductive hormone. In the ensuing decades, many additional activities of activin were described and it was found to be produced in a wide variety of cell types at nearly all stages of development. Its signaling and actions are regulated intracellularly and by extracellular antagonists. Over the past 5 years, a number of important advances have been made that clarify our understanding of the structural basis for signaling and regulation, as well as the biological roles of activin in stern cells, embryonic development and in adults. These include the crystallization of activin in complex with the activin type II receptor ActRIIB, or with the binding proteins follistatin and follistatin-like 3, as well as identification of activin's roles in gonadal sex development, follicle development, luteolysis, beta-cell proliferation and function in the islet, stem cell pluripotency and differentiation into different cell types and in immune cells. These advances are reviewed to provide perspective for future studies. journal of Endocrinology (2009) 202, 1-12

AB Thyroid hormone is known to affect myocardial glycogen stores and thereby possibly limit anaerobic performance of mammalian cardiac muscle. Thyroid hormone administration (3,5,T-triiodo-L-thyroxine, 300 mu g/kg/day, sc) for 10 days decreased left ventricle (LV) glycogen concentration relative to euthyroid animals (2.78 +/- 0.46 vs. 4.28 +/- 0.29 mg/g of LV (mean +/- SEM)) while increasing the percent of V(1) myosin isozyi-ne, contractile activity and cardiac mass. In contrast, thyroidectomy increased myocardial glycogen stores (8.50 +/- 0.56 mg/g of LV) and shifted the myosin isozyme toward V(3), prolonged contractile activity and decreased LV mass. Thyroxine administration for 3, 7 and 10 days to thyroidectomized animals progressively decreased contractile duration and increased LV mass. Thyroxine administration for 3 or 7 days to thyroidectomized rats did not reduce glycogen stores (7.75 +/- 1.02 and 9.62 +/- 1.16 mg/g of LV, respectively), whereas myocardial glycogen declined to 3.30 +/- 0.58 mg/g of LV after 10 days of treatment. During hypoxia, cardiac muscle from thyroidectomized rats maintained greater active force and developed less contracture relative to euthyroid and, to a greater extent, than hyperthyroid rats. Removal of glucose from the bath decreased anaerobic performance and impaired recovery; however, myocardium from thyroidectomized rats remained more tolerant to hypoxia than the euthyroid group. Overall, the intrinsic LV glycogen content was positively correlated to anaerobic performance. These data demonstrate that the thyroid state profoundly affects myocardial growth, contractility and anaerobic performance of rat myocardium. Although energy demand may affect function during hypoxia, anaerobic substrate reserve (cardiac glycogen concentration) appears to be the primary factor determining tolerance to hypoxic stress. J.

HEPATOLITHIASIS
AB Background and Aim:
Little is known about the role of platelet-derived growth factor (PDGF) in biliary fibrosis in the setting of bacterial colonization of the biliary tree. We therefore sought to investigate whether exposure to bacterial lipopolysaccharide (LPS) alters PDGF isoform and receptor expression in cultured rat common bile duct fibroblasts (CBDF) and normal rat cholangiocytes (NRC).
Methods:
Collagen content in cells and media was assessed by colorimetric assay and gel electrophoresis. mRNA levels of PDGF-A and -B, and PDGF-Receptors (PDGF-R) alpha and beta were measured by relative quantitative real-time PCR. Protein levels of PDGF-AA, AB and BB were measured by ELISA, and PDGF-R alpha and PDGF-R beta by Western blot.
Results:
In CBDF, LPS increased total soluble collagen synthesis and secretion. PDGF-R alpha and beta mRNA and protein were also increased by LPS treatment in CBDF. Lipopolysaccharide treatment elicited an increase in PDGF-A and -B mRNA levels in CBDF. In NRC, levels of PDGF-A mRNA increased in a dose-dependent fashion following LPS treatment, whereas PDGF-B mRNA showed no response. PDGF-AA secretion was higher by CBDF than by NRC. PDGF-BB levels were also higher in CBDF than in NRC. While PDGF-BB levels did not respond to LPS treatment in CBDF, there was a dose-dependent response of this isoform to LPS in NRC. Intracellular and secreted PDGF-AB increased with LPS treatment in NRC.
Conclusions:
These results support a model in which chronic bacterial colonization of the biliary tree induces fibrosis through PDGF-dependent mechanisms.

AB BRCA1/2 testing is one of the most well-established genetic tests to predict cancer risk. Guidelines are available to help clinicians determine who will benefit most from testing.
To identify women at high risk of hereditary breast and ovarian cancer and estimate their awareness of and experience with genetic testing for cancer risk.
Analyses of the 2000 and 2005 National Health Interview Surveys.
Women with no personal history of breast or ovarian cancer (n = 35,116).
Risk of hereditary breast or ovarian cancer based on self-reported family history of cancer and national guidelines; self-reported awareness of genetic testing for cancer risk; discussion of genetic testing for cancer risk with a health professional; having undergone genetic testing for breast/ovarian cancer risk.
Using guideline criteria, 0.96% of women were identified as being at high risk of hereditary breast and ovarian cancer. Among high-risk women, 54.04% were aware of genetic testing for cancer risk, 10.39% had discussed genetic testing with a health professional, and 1.41% had undergone testing for breast/ovarian cancer risk. Adjusting for survey year, high-risk women were more likely than average-risk women to have heard of genetic testing for cancer risk (RR, 1.3, 95% CI 1.2-1.4), to have discussed genetic testing with a health professional (RR 5.2, 95% CI 3.6-7.4), and to have undergone genetic testing for breast/ovarian cancer risk (RR 6.8, 95% CI 2.6-18.0).
We find low provision of guideline-recommended advice to women for whom testing may be appropriate and of significant clinical benefit.

AB Homeless persons depend disproportionately on the health-care safety net for medical services. National reports identify financial strains to this safety net. Whether this has affected homeless persons is unknown.
We quantified changes in the proportion of homeless persons reporting unmet need for health care in Birmingham, Alabama, comparing two periods, 1995 and 2005. We assessed whether a period effect was independent of characteristics of persons surveyed.
Analysis of two surveys conducted with identical methods among representative samples of homeless persons in 1995 (n = 161) and 2005 (n = 161).
Report of unmet need (inability to obtain care when needed) was the dependent variable. Two survey periods (1995 and 2005) were compared, with multivariable adjustment for sociodemographic and health characteristics. Reasons for unmet need were determined among the subset of persons reporting unmet need.
Unmet need for health care was more common in 2005 (54%) than in 1995 (32%) (p < 0.0001), especially for non-Blacks (64%) and females (65%). Adjusting for individual characteristics, a survey year of 2005 independently predicted unmet need (odds ratio 2.68, 95% CI 1.49-4.83). Among persons reporting unmet need (87 of 161 in 2005; 52 of 161 in 1995), financial barriers were more commonly cited in 2005 (67% of 87) than in 1995 (42% of 52) (p = 0.01).
A rise in unmet health-care needs was reported among Birmingham's homeless from 1995 to 2005. This period effect was independent of population characteristics and may implicate a local safety net inadequacy. Additional data are needed to determine if this represents a national trend.

AB Pay-for-performance is proliferating, yet its impact on key stakeholders remains uncertain.
The Society of General Internal Medicine systematically evaluated ethical issues raised by performance-based physician compensation.
We conclude that current arrangements are based on fundamentally acceptable ethical principles, but are guided by an incomplete understanding of health-care quality. Furthermore, their implementation without evidence of safety and efficacy is ethically precarious because of potential risks to stakeholders, especially vulnerable patients.
We propose four major strategies to transition from risky pay-for-performance systems to ethical performance-based physician compensation and high quality care. These include implementing safeguards within current pay-for-performance systems, reaching consensus regarding the obligations of key stakeholders in improving health-care quality, developing valid and comprehensive measures of health-care quality, and utilizing a cautious evaluative approach in creating the next generation of compensation systems that reward genuine quality.

TI Management of Radial Nerve Palsy Associated With Humeral Shaft Fracture:
A Decision Analysis Model
SO JOURNAL OF HAND SURGERY-AMERICAN VOLUME
LA English
DT Article
DE Decision analysis; fracture; humerus; nerve palsy; radial nerve
ID VISUAL ANALOG SCALE; PARALYSIS; UTILITY; TENDON
AB Purpose When managing radial nerve palsy associated with a humerus fracture, both surgeon and patient must balance the risks and benefits of performing an invasive surgical procedure to address a functional deficit that is likely, but not certain, to recover with nonsurgical management. The purpose of this study was to better understand the determinants of optimal management strategy using expected-value decision analysis.
Methods Probabilities for the occurrences of the potential outcomes after initial observation or early surgery were determined from a systematic review of the literature. Scores for these outcomes were obtained from a questionnaire on patient preferences completed by 82 subjects without a history of humerus fracture and radial nerve palsy and used in the model as a measure of utility. A decision tree was constructed, fold-back analysis was performed to determine optimal treatment, and sensitivity analyses were used to determine the effect on decision making of varying outcome probabilities and utilities.
Results Observation was associated with a value of 8.4 and early surgery a value of 6.7 given the outcome probabilities and utilities studied in this model, making observation the optimal management strategy. When parameters were varied in sensitivity analysis, it was noted that when the rate of recovery after initial observation falls below 40% or when the utility value for successful early surgery rises above 9.4, early surgery is the preferred management strategy.
Conclusions Initial observation was the preferred strategy. In clinical settings in which the likelihood of spontaneous recovery of nerve function is low or when an informed patient has a strong preference for surgery, early surgery may optimize outcome.

TI Magnetic Resonance Imaging Signal Abnormalities in Enthesopathy of the
Extensor Carpi Radialis Longus Origin

DE Lateral epicondylosis; lateral collateral ligament; tear; magnetic

ID LATERAL EPICONDYLITIS; ROTATOR-CUFF; SURGICAL-TREATMENT; TENNIS ELBOW;
INSTABILITY; INJECTIONS
AB Purpose Some surgeons use magnetic resonance imaging (MRI) findings in patients with enthesopathy of the extensor carpi radialis brevis (ECRB) origin (commonly referred to as lateral epicondylitis) to plan and justify surgical treatment. Overinterpretation of defects of the origin of the ECRB or associated abnormalities of the lateral collateral ligament (LCL) could affect decision-making. We tested the hypothesis that patients with MRI signal abnormalities consistent with enthesopathy of the ECRB are equally likely to have findings consistent with an ECRB defect or LCL abnormality whether they are being evaluated as part of preoperative planning for lateral elbow pain or for an elbow condition that does not feature lateral elbow pain.
Methods For each of 24 consecutive patients with enthesopathy of the ECRB who had MRI for preoperative evaluation, we selected 2 age- and gender-matched controls from a list of patients who had an elbow MRI to evaluate other elbow problems. The origin of the ECRB and the LCL were specifically evaluated.
Results Patients diagnosed with enthesopathy of the ECRB were significantly more likely than control patients to have signal changes consistent with enthesopathy of the ECRB origin (24 of 24 vs 9 of 48; p < .001). The proportion of patients with a partial thickness defect of the ECRB origin (14 of 24 vs 4 of 9) was comparable between patients diagnosed with enthesopathy of the ECRB origin and controls. Signal changes in the LCL were comparable in patients diagnosed with enthesopathy of the ECRB origin and control patients (8 of 24 vs 2 of 9; p = .27), and no patient had clinical evidence of instability.
Conclusions Use of MRI in the management of patients with enthesopathy of the ECRB origin merits further study. (J Hand Surg 2009;34A:1094-1098. (C) 2009 Published by Elsevier Inc. on behalf of the American Society for Surgery of the Hand)

AB Purpose Returning patients to work may be influenced by subjective factors and physician bias. The purpose of this study was to determine whether factors such as complaints of pain and patient motivation influence physicians' recommendations regarding return to work or activity.
Methods One hundred twenty-five members of the American Society for Surgery of the Hand completed an online survey describing a 25-year-old patient with surgically treated diaphyseal fractures of the radius and ulna. Physicians were asked whether the patient could be returned to work in 4 distinct scenarios varying with occupation, time since injury, radiographic union, patient motivation, and pain.
Results Logistic regression analysis demonstrated that all 5 predictor variables were highly significant predictors of return to work. Pain and diminished motivation were associated with a significantly lower probability of return to work.
Conclusions Although in the scenario depicted, objective factors such as radiographic union and job demands are the major determinants of physician clearance to return to work, physicians are also influenced by patient motivation and complaints of pain.

AB Non-alcoholic fatty liver disease (NAFLD) has become the most common liver disorder of our times. Simple steatosis, a seemingly innocent manifestation of NAFLD, may progress into steatohepatitis and cirrhosis, but this process is not well understood. Since NAFLD is associated with obesity and insulin resistance, mechanisms that link lipid metabolism to inflammation offer insights into the pathogenesis. An important parallel between obesity-related pathology of adipose tissue and liver pertains to the emerging role of macrophages and evidence is growing that Kupffer cells critically contribute to progression of NAFLD. Toll-like receptors, in particular TLR4, represent a major conduit for danger recognition linked to Kupffer cell activation and this process may be perturbed at multiple steps in NAFLD. Steatosis may interfere with sinusoid microcirculation and hepatocellular clearance of microbial and host-derived danger signals, enhancing responsiveness of Kupffer cells. Altered lipid homeostasis in NAFLD may unfavourably affect TLR4 receptor complex assembly and sorting, interfere with signalling flux redistribution, promote amplification loops, and impair negative regulation including alternative activation of Kupffer cells. These events are further promoted by altered adipokine secretion and reactive oxygen species production. Specific targeting of these interactions may provide more effective strategies in the treatment of NAFLD. Published by Elsevier B.V. on behalf of the European Association for the Study of the Liver.

AB CD1d-restricted invariant NKT (iNKT) cells play crucial roles in various types of immune responses, including autoimmune diseases, infectious diseases and tumor surveillance. The mechanisms underlying their adjuvant functions are well understood. Nevertheless, although IL-4 and IL-10 production characterize iNKT cells able to prevent or ameliorate some autoimmune diseases and inflammatory conditions, the precise mechanisms by which iNKT cells exert immune regulatory function remain elusive. This study demonstrates that the activation of human iNKT cells by their specific ligand alpha-galactosylceramide enhances IL-12p70 while inhibiting the IL-23 production by monocyte-derived dendritic cells, and in turn down-regulating the IL-17 production by memory CD4(+) Th cells. The ability of the iNKT cells to regulate the differential production of IL-12p70/IL-23 is mainly mediated by a remarkable hallmark of their function to produce both Th1 and Th2 cytokines. In particular, the down-regulation of IL-23 is markedly associated with a production of IL-4 and IL-10 from iNKT cells. Moreover, Th2 cytokines, such as IL-4 and IL-13 play a crucial role in defining the biased production of IL-12p70/IL-23 by enhancement of IL-12p70 in synergy with IFN-gamma, whereas inhibition of the IFN-gamma-promoted IL-23 production. Collectively, the results suggest that iNKT cells modify the IL-12p70/IL-23 balance to enhance the IL-12p70-induced cell-mediated immunity and suppress the IL-23-dependent inflammatory pathologies. These results may account for the long-appreciated contrasting beneficial and adverse consequence of ligand activation of iNKT cells. The Journal of Immunology, 2009, 183: 201-208.

AB The pathogenesis of human inflammatory bowel disease (IBD) and most experimental models of IBD is dependent on the activation and expansion of CD4(+) T cells via interaction with mucosal APCs. The costimulatory receptor CD70 is transiently expressed on the surface of conventional dendritic cells, but is constitutively expressed by a unique APC population in the intestinal lamina propria. We used two experimental IBD models to evaluate whether interfering the interaction between CD70 and its T cell ligand CD27 would affect the development of colitis. Adoptive transfer of naive CD27-deficient CD45RB(high) CD4(+) T cells into Rag-1(-/-) mice resulted in significantly less disease than when wild-type CD45RB(high) CD4(+) T cells were used. Moreover, a monoclonal anti-CD70 Ab prevented the disease caused by the transfer of wild-type CD45RB(high) CD4(+) T cells into Rag-1(-/-) mice and the same Ab also ameliorated an established disease. The colitis associated proinflammatory cytokines IL-6, TNF-alpha and IFN-gamma were significantly reduced after anti-CD70 Ab treatment, suggesting an overall reduction in inflammation due to blockade of pathogenic T cell expansion. Anti-CD70 Ab treatment also suppressed trinitrobenzene sulfonic acid-induced colitis in SJL/J mice. Because anti-CD70 Ab treatment suppressed multiple proinflammatory cytokines, this may be a more potent therapeutic approach for IBD than blockade of individual cytokines.

AB West Nile virus is an emerging pathogen that can cause fatal neurological disease. A recombinant human mAb, mAb11, has been described as a candidate for the prevention and treatment of West Nile disease. Using a yeast surface display epitope mapping assay and neutralization escape mutant, we show that mAb11 recognizes the fusion loop, at the distal end of domain 11 of the West Nile virus envelope protein. Ab mAb11 cross-reacts with all four dengue viruses and provides protection against dengue (serotypes 2 and 4) viruses. In contrast to the parental West Nile virus, a neutralization escape variant failed to cause lethal encephalitis (at higher infectious doses) or induce the inflammatory responses associated with blood-brain barrier permeability in mice, suggesting an important role for the fusion loop in viral pathogenesis. Our data demonstrate that an intact West Nile virus fusion loop is critical for virulence, and that human mAb11 targeting this region is efficacious against West Nile virus infection. These experiments define the molecular determinant on the envelope protein recognized by mAb11 and demonstrate the importance of this region in causing West Nile encephalitis.

AB Objectives: In patients with ventilator-associated pneumonia (VAP), Pseudomonas aeruginoso type III (TTSS) secreting isolates have been linked to poor clinical outcomes. Differential expression of matrix metalloproteinases (MMPs) induced by type III effector proteins may herald an irreversible lung injury.
Methods: Serial bronchoalveolar lavage fluids collected from 41 patients with P. aeruginoso at onset of VAP, day 4, and day 8 after antibiotic therapy were assayed for MMP-8, MMP-9, tissue inhibitor of metalloproteinase-1 (TIMP-1), and alpha-2 macroglobulin levels.
Results: At the onset of VAP, isolates secreting ExoU had the highest MMP-9 levels. The response to antimicrobial therapy showed a differential drop in MMPs with significant decrease in MMP-8 and MMP-9 levels on days 4 and 8 in patients with TTSS- compared to TTSS+ phenotype. The ratio of MMP-9/TIMP-1 was significantly associated with alpha-2 macroglobulin at end of therapy (r = 0.4, p = 0.02). Patients who survived had a tower MMP-9/TIMP-1 ratio than those who died (p = 0.003).
Conclusions: VAP linked to A aeruginosa Type III phenotype portrays a divergent antibiotic treatment response in regards to the concentrations of metalloproteinases in the alveolar space. The imbalance between MMP-9 and TIMP-1 may determine the intensity of alveolocapillary damage and ultimate outcome of P. aeruginosa VAP.

TI ATR-Chk1 Pathway Inhibition Promotes Apoptosis after UV Treatment in
Primary Human Keratinocytes: Potential Basis for the UV Protective
Effects of Caffeine

AB New approaches to prevent and reverse UV damage are needed to combat rising sunlight-induced skin cancer rates. Mouse studies have shown that oral or topical caffeine promotes elimination of UV-damaged keratinocytes through apoptosis and markedly inhibits subsequent skin cancer development. This potentially important therapeutic effect has not been studied in human skin cells. Here, we use primary human keratinocytes to examine which of several caffeine effects mediates this process. In these cells, caffeine more than doubled apoptosis after 75 mJ cm(-2) of ultraviolet light B (UVB). Selectively targeting two of caffeine's known effects did not alter UVB-induced apoptosis: inhibition of ataxia-telangiectasia mutated and augmentation of cyclic AMP levels. In contrast, siRNA against ataxia-telangiectasia and Rad3-related (ATR) doubled apoptosis after UV through a p53-independent mechanism. Caffeine did not further augment apoptosis after UVB in cells in which ATR had been specifically depleted, suggesting that a key target of caffeine in this effect is ATR. Inhibition of a central ATR target, checkpoint kinase 1 (Chk1), through siRNA or a new and highly specific inhibitor (PF610666) also augmented UVB-induced apoptosis. These data suggest that a relevant target of caffeine is the ATR-Chk1 pathway and that inhibiting ATR or Chk1 might have promise in preventing or reversing UV damage.

AB The mechanism of increased MTb disease susceptibility in HIV+ persons remains poorly understood. Apoptosis of macrophages in response to MTb represents a critical host defense response, and decreased apoptosis may represent a mechanism of increased susceptibility to MTb in HIV. In the current study, MTb-mediated apoptosis of human AM was reduced in HIV+ subjects compared with healthy subjects in a TNF-alpha-dependent manner. IL-10 levels in BALF from HIV+ persons were significantly elevated compared with HIV-persons, and exogenous IL-10 reduced MTb-mediated apoptosis in healthy AM, suggesting that IL-10 could mediate decreased apoptosis observed in HIV. Further study showed that IL-10 reduced TNF release in response to MTb in AM through a reduction in TNF mRNA levels, and exogenous TNF could partially reverse IL-10-associated effects on AM apoptosis. IL-10 did not influence p-IRAK, I kappa B degradation, or NF-kappa B p65 nuclear translocation in response to MTb, but IL-10 did increase levels of AM BCL-3, an inhibitor of NF-kappa B nuclear activity. BCL-3 knockdown in human macrophages increased MTb-mediated TNF release. Importantly, BCL-3 levels in AM from HIV+ subjects were higher compared with healthy subjects. Taken together, these data suggest that elevated lung levels of IL-10 may impair MTb-mediated AM apoptosis in HIV through a BCL-3-dependent mechanism. BCL-3 may represent a potential therapeutic target to treat or prevent MTb disease in HIV+ persons. J. Leukoc. Biol. 86: 53-60; 2009.

AB This study reports preliminary findings regarding the feasibility and efficacy of a novel couple-based treatment, named Strategic Approach Therapy (SAT), for reducing avoidance symptoms of posttraumatic stress disorder (PTSD). Six male Vietnam combat veterans diagnosed with PTSD and their cohabitating marital partners participated in 10 weeks of SAT treatment. Self-report, clinician ratings, and partner ratings of PTSD symptoms were obtained before the first session and after the tenth session of treatment. Veterans reported statistically significant reductions in self-reported, clinician-rated, and partner-rated effortful avoidance, emotional numbing, and overall PTSD severity. These data indicate that SAT offers promise as an effective treatment for PTSD avoidance symptoms.

AB Risk-benefit assessment is a routine requirement for research ethics committees that review and oversee biomedical research with human subjects. Nevertheless, it remains unclear how to weigh and balance risks to research participants against the social benefits that flow from generating biomedical knowledge. In this article, we address the question of whether there are any reasonable criteria for defining the limit of permissible risks to individuals who provide informed consent for research participation. We argue against any a priori limit to permissible research risks. However, attention to the uncertainty of potential social benefit that can be derived from any particular study warrants caution in exposing prospective research participants to a substantial likelihood of serious harm.

AB Background: Lymphangioleiomyomatosis (LAM) is a prominent finding in the setting of tuberous sclerosis complex (TSC).
Objective: The present study was designed to compare cystic lung changes consistent with LAM in patients with a TSC1 disease-causing mutation, TSC2 disease-causing mutation, or no mutation identified (NMI).
Methods and results: We conducted a retrospective review of the chest computed tomography (CT) of 45 female and 20 male patients with TSC and found cysts consistent with LAM in 22 (49%) women and two (10%) men. In the female population, changes consistent with LAM were observed in six of 15 (40%) patients with TSC1, 11 of 23 (48%) with TSC2, and five of seven (71%) with NMI. While the predominant size of cysts did not differ across these three groups, TSC2 women with LAM had a significantly greater number of cysts than did TSC1 patients (p = 0.010).
Conclusions: These findings suggest a higher rate of LAM in TSC1 than previously recognised, as well as a fundamental difference in CT presentation between TSC1 and TSC2.

AB Hepatitis C is one of the most common chronic infectious diseases worldwide, with well-documented extra-hepatic manifestations, such as a broad number of cognitive deficits. These impairments may be explained by psychiatric comorbidities, which have not been investigated properly in the literature. In order to elucidate a specific hepatitis C virus (HCV) induced cognitive impairment not related to mental disorders, neuropsychological performance of patients infected with HCV was compared with that of patients infected with hepatitis B virus cognitive impairment, especially psychiatric comorbidities. A total of 33 patients infected with HCV and 22 patients infected with HBV were included in the study. There were no significant differences between the two groups with regard to age or years of education. The group of patients infected with HCV performed significantly worse on visuo-spatial memory tasks after adjusting for years of education and age. There were no significant differences between patients infected with HCV and patients infected with HBV with regards to other neuropsychological functions. The data indicate that patients infected with HCV patients have poorer visuo-spacial memory performance than patients infected with HBV, suggesting that the cognitive deficit may be specific to HCV infection and not to secondary comorbid psychiatric disorders.

AB Changes in representative dopamine (D(1), D(2), and D(4)) and serotonin (5-HT(1A) and 5-HT(2A)) receptors that have been implicated in the pathophysiology and treatment of schizophrenia were autoradiographically quantified after subchronic phencyclidine (PCP) treatment (2 mg/kg for 7 days, bi-daily followed by 7 days drug free). This treatment has consistently induced robust and long-lasting cognitive deficits in adult rats, although the molecular mechanisms contributing to PCP-induced cognitive deficits remain undefined. Repeated PCP treatment significantly decreased labeling of D(1) receptors in the medial and lateral caudate-putamen (22% and 23%, respectively) and increased 5HT(1A) receptor binding in the medial-prefrontal (26%) and dorsolateral-frontal cortex (30%). No changes in D(1) or 5HT(1A) receptors were detected in other brain regions. These findings suggest that downregulation of striatal D(1) receptors and upregulation of cortical 5HT(1A) receptors may contribute to PCP-induced impairment of cognitive functions in rats. Subchronic PCP treatment did not alter levels of D(2), D(4), and 5HT(2A) receptors in all brain regions examined, which suggests a minimal role for these receptors in mediating subchronic actions of PCP in adult rats.

AB Phosphorylation of neurotransmitter receptors can modify their activity and regulate neuronal excitability. Cyclin-dependent kinase 5 (cdk5) is a proline-directed serine/threonine kinase involved not only in neuronal development, but also in synaptic function and plasticity. Here we demonstrate that group I metabotropic glutamate receptors (mGluRs), which modulate post-synaptic signaling by coupling to intracellular signal transduction pathways, are phosphorylated by cdk5. In vitro kinase assays reveal that cdk5 phosphorylates mGluR5 within the domain of the receptor that interacts with the scaffolding protein homer. Using a novel phosphospecific mGluR antibody, we show that the homer-binding domain of both mGluR1 and mGluR5 are phosphorylated in vivo, and that inhibition of cdk5 with siRNA decreases the amount of phosphorylated receptor. Furthermore, kinetic binding analysis, by surface plasmon resonance, indicates that phosphorylation of mGluR5 enhances its association with homer. Homer protein complexes in the post-synaptic density, and their disruption by an activity-dependent short homer 1a isoform, have been shown to regulate the trafficking and signaling of the mGluRs and impact many neuroadaptive processes. Phosphorylation of the mGluR homer-binding domain, in contrast to homer 1a induction, provides a novel mechanism for potentially regulating a subset of homer interactions.

TI Case volumes of intra-arterial and intravenous treatment of ischemic
stroke in the USA
SO JOURNAL OF NEUROINTERVENTIONAL SURGERY

ID THROMBOLYTIC THERAPY; RECANALIZATION; INTERVENTION; REGISTRY; TRIAL;
TIME
AB Background and purpose: Ischemic stroke is a major cause of disability and death in the USA. Intravenous tissue plasminogen activator (t-PA) remains underutilized. With the development of newer intra-arterial reperfusion therapies, there is increased opportunity to address the more devastating large-vessel occlusions. We seek to identify the numbers of patients with stroke treated with intravenous and intra-arterial therapies, as well as to estimate the potential number of intra-arterial cases in the foreseeable future.
Methods: We performed a literature search to determine case volumes of intravenous t-PA use. We extrapolated the current case volume of intra-arterial stroke therapies from the numbers of cases in which the Merci retrieval device was used. In order to estimate the potential numbers of intra-arterial stroke cases, we characterized the percentage of patients with stroke who received intra-arterial therapy at two leading stroke centers. We applied these percentages to the numbers of patients with stroke seen at the top 100, 200 and 500 stroke centers by volume.
Results: The rate of intravenous t-PA use is 2.4-3.6%, resulting in 15 000-22 000 cases/year in the USA. The estimated case volume of intra-arterial therapies is 3500-7200 in 2006. Based on data from St. Luke's Brain and Stroke Institute and Massachusetts General Hospital, approximately 5-20% of patients with ischemic stroke can be treated with intra-arterial therapies. Extrapolating this to the top 500 stroke centers by volume, the potential number of intra-arterial cases in the USA is 10 400-41 500/ year.
Conclusion: Based on the current numbers of intra-arterial cases, our theoretical model identifies a potential for significant growth of this stroke therapy.

AB Since the 1920s, it has been known that the repetitive brain trauma associated with boxing may produce a progressive neurological deterioration, originally termed dementia pugilistica, and more recently, chronic traumatic encephalopathy (CTE). We review 48 cases of neuropathologically verified CTE recorded in the literature and document the detailed findings of CTE in 3 professional athletes, 1 football player and 2 boxers. Clinically, CTE is associated with memory disturbances, behavioral and personality changes, parkinsonism, and speech and gait abnormalities. Neuropathologically, CTE is characterized by atrophy of the cerebral hemispheres, medial temporal lobe, thalamus, mammillary bodies, and brainstem, with ventricular dilatation and a fenestrated cavum septum pellucidum. Microscopically, there are extensive tau-immunoreactive neurofibrillary tangles, astrocytic tangles, and spindle-shaped and threadlike neurites throughout the brain. The neurofibrillary degeneration of CTE is distinguished from other tauopathies by preferential involvement of the superficial cortical layers, irregular patchy distribution in the frontal and temporal cortices, propensity for sulcal depths, prominent perivascular, periventricular, and subpial distribution, and marked accumulation of tau-immunoreactive astrocytes. Deposition of beta-amyloid, most commonly as diffuse plaques, occurs in fewer than half the cases. Chronic traumatic encephalopathy is a neuropathologically distinct slowly progressive tauopathy with a clear environmental etiology.

AB Neurofibrillary tangles (NFTs) are associated with neuronal loss and correlate with cognitive impairment in Alzheimer disease, but how NFTs relate to neuronal death is not clear. We studied cell death in Tg4510 mice that reversibly express P301L mutant human tau and accumulate NFTs using in vivo multiphoton imaging of neurofibrillary pathology, propidium iodide (PI) incorporation into cells, caspase activation, and DNA labeling. We first observed that in live trice, a minority of neurons were labeled with the caspase probe or with PI fluorescence. These markers of cell stress were localized in the same cells and appeared specifically within NFT-bearing neurons. Contrary to expectations, the PI-stained neurons did not die during a day of observation; the presence of Hoechst-positive nuclei in them on the subsequent day indicated that the NFT-associated membrane disruption, as suggested by PI staining, and caspase activation do not lead to immediate death of neurons in this tauopathy model. This unique combination of in vivo multiphoton imaging with markers of cell death and pathological alteration is a powerful tool for investigating neuronal damage associated with neurofibrillary pathology.

AB It is traditionally thought that excitotoxic necrosis is a passive mechanism that does not require the activation of a cell death program. In this study, we examined the contribution of the cytochrome c-dependent mitochondrial death pathway to excitotoxic neuronal necrosis, induced by exposing cultured cortical neurons to 1 mM glutamate for 6 hr and blocked by the NMDA antagonist, dizocilpine. Glutamate treatment induced early cytochrome c release, followed by activation of caspase-9 and caspase-3. Preincubation with the caspase-9 inhibitor z-LEHD-fmk, the caspase-3 inhibitor z-DEVD-fmk, or the specific pan-caspase inhibitor Q-VD-oph decreased the percentage of propidium iodide-positive neurons (52.5% +/- 3.1%, 39.4% +/- 3.5%, 44.6% +/- 3%, respectively, vs. 65% +/- 3% in glutamate + vehicle). EM studies showed mitochondrial release of cytochrome c in neurons in the early stages of necrosis and cleaved caspase-3 immunoreactivity in morphologically necrotic neurons. These results suggest that an active mechanism contributes to the demise of a sub-population of excitotoxic necrotic neurons. (C) 2009 Wiley-Liss, Inc.

AB Subependymal giant cell tumors (SGCTs) are observed in 5-20% of patients with tuberous sclerosis complex (TSC) but account for similar to 25% of neurological morbidity. The authors report the case of a 7-year-old girl with TSC and multiple cortical tubers who presented with worsening seizures in the context of the rapid growth of a cystic, calcified, extraventricular SGCT in the right frontal lobe, initially thought to represent a cortical tuber. The tumor and Surrounding tubers were excised, and clinical seizures resolved. This is the first report of an extraventricular SGCT in a child with TSC outside the neonatal period.

AB The authors describe a method of harvesting autologous pericranium for duraplasty in patients with Chiari malformation Type I (CM-I) that avoids excessive exposure or a second incision. Nonautologous dural grafts have been associated with numerous complications including hemorrhage, bacteria and virus transmission, fatal Creutzfeldt-Jakob disease transmission, foreign body reaction, systemic immune response, excessive scarring. slower healing, premature graft dissolution, and wound dehiscence. Autogenous tissues have the advantage of being nonimmunogenic, nontoxic, readily available, and inexpensive. Pericranium is a preferred substrate because it is flexible, strong, and easily Sutured for a watertight closure. Current literature supports the use of autogenous pericranium for dural grafting in CM-I procedures, but has heretofore failed to provide a method of harvest that avoids the complications associated with a larger exposure or second incision. The authors offer a simple alternative technique for using local pericranium in duraplasty for CM-I or other posterior fossa abnormalities. (DOI:10.3171/2009.3.SPINE08196)

AB Patients with mild traumatic brain injury (TBI) often complain of cognitive fatigue during the chronic recovery phase. The Paced Auditory Serial Addition Test (PASAT) is a complex psychologic measure that may demonstrate subtle deficiencies in higher cognitive functions. The purpose of this study was to investigate the brain activation of regional cerebral blood flow (rCBF) with PASAT in patients with mild TBI to explore mechanisms for the cognitive fatigue. Methods: Two groups consisting of 15 patients with mild TBI and 15 healthy control subjects underwent (99m)Tc-ethylene cysteine dimer SPECT at rest and during PASAT on a separate day. Cortical rCBF was extracted using a 3-dimensional stereotactic surface projection and statistically analyzed to identify areas of activation, which were compared with PASAT performance scores. Results: Image analysis demonstrated a difference in the pattern of activation between patients with mild TBI and healthy control subjects. Healthy control subjects activated the superior temporal cortex (Brodmann area [BA] 22) bilaterally, the precentral gyrus (BA 9) on the left, and the precentral gyrus (BA 6) and cerebellum bilaterally. Patients with mild TBI demonstrated a larger area of supratentorial activation (BAs 9, 10, 13, and 46) but a smaller area of activation in the cerebellum, indicating frontocerebellar dissociation. Conclusion: Patients with mild TBI and cognitive fatigue demonstrated a different pattern of activation during PASAT. Frontocerebellar dissociation may explain cognitive impairment and cognitive fatigue in the chronic recovery phase of mild traumatic brain injury.

AB (82)Rb cardiac PET allows the assessment of myocardial perfusion with a column generator in clinics that lack a cyclotron. There is evidence that the quantitation of myocardial blood flow (MBF) and coronary flow reserve (CFR) with dynamic (82)Rb PET is feasible. The objectives of this study were to determine the accuracy and reproducibility of MBF estimates from dynamic (82)Rb PET by using our methodology for generalized factor analysis (generalized factor analysis of dynamic sequences [GFADS]) and compartment analysis. Methods: Reproducibility was evaluated in 22 subjects undergoing dynamic rest and dipyridamole stress (82)Rb PET studies at a 2-wk interval. The inter-and intraobserver variability of MBF quantitation with dynamic (82)Rb PET was assessed with 4 repeated estimations by each of 4 observers. Accuracy was evaluated in 20 subjects undergoing dynamic rest and dipyridamole stress PET studies with (82)Rb and (13)N-ammonia, respectively. The left ventricular and right ventricular blood pool and left ventricular tissue time-activity curves were estimated by GFADS. MBF was estimated by fitting the blood pool and tissue time-activity curves to a 2-compartment kinetic model for (82)Rb and to a 3-compartment model for (13)N-ammonia. CFR was estimated as the ratio of peak MBF to baseline MBF. Results: The reproducibility of the MBF estimates in repeated (82)Rb studies was very good at rest and during peak stress (R(2) = 0.935), as was the reproducibility of the CFR estimates (R(2) = 0.841). The slope of the correlation line was very close to one for the estimation of MBF (0.986) and CFR (0.960) in repeated (82)Rb studies. The intraobserver reliability was less than 3% for the estimation of MBF at rest and during peak stress as well as for the estimation of CFR. The interobserver reliabilities were 0.950 at rest and 0.975 at peak stress. The correlation between myocardial flow estimates obtained at rest and those obtained during peak stress in (82)Rb and (13)N-ammonia studies was very good (R(2) = 0.857). Bland-Altman plots comparing CFR estimated with (82)Rb and CFR estimated with (13)N-ammonia revealed an underestimation of CFR with (82)Rb compared with (13)N-ammonia; the underestimation was within 61.96 SD. Conclusion: MBF quantitation with GFADS and dynamic (82)Rb PET demonstrated excellent reproducibility as well as intra- and inter-observer reliability. The accuracy of the absolute quantitation of MBF with factor and compartment analyses and dynamic (82)Rb PET was very good, compared with that achieved with (13)N-ammonia, for MBF of up to 2.5 mL/g/min.

ID RECOGNITION PROGRAM; SATISFACTION; HOSPITALS; MORTALITY; BURNOUT; RNS
AB Objectives: To compare how registered nurses view the work environment and the nursing shortage based on the Magnet status of their organizations.
Background: The upsurge in organizations pursuing and obtaining Magnet recognition provides increased opportunities to investigate whether and how registered nurses who are employed in Magnet organizations and organizations pursuing Magnet status perceive differences in the nursing shortage, hospitals' responses to the shortage, characteristics of the work environment, and professional relationships.
Methods: A nationally representative sample of registered nurses licensed to practice in the United States was surveyed. The views of registered nurses who worked in Magnet organizations, organizations in the process of applying for Magnet status, and non-Magnet organizations were analyzed as independent groups.
Results: Significant differences were found. Although there is a clear Magnet difference, there are also identifiable differences that occur during the pursuit of Magnet recognition.
Conclusion: Many organizations in the process of applying for Magnet status rated higher than Magnet organizations, indicating that there is much to do to maintain the comparative advantages for Magnet hospitals.

AB This article examines whether a patient safety "champion" on an ambulatory, chemotherapy infusion unit can increase reporting of adverse events and close calls. Reporting rates increased substantially oil both intervention and control units. It was accompanied by more reports of medical errors and conditions that worried staff and fewer reports of service quality incidents. The facilitated reporting method described here is a novel approach to incident reporting, complements the spontaneous reporting systems used in hospitals and some ambulatory care settings, and may help to build a safety culture. By identifying errors and worrisome conditions, it may help managers identify problems before they lead to harm.

AB Purpose: Intimate partner violence (IPV) frequently results in maxillofacial injuries. The purpose of this study is to compare 2 protocols to identify women who self-report IPV-related injuries.
Materials and Methods: Using a cross-sectional study design, we enrolled a sample of injured women who presented to the emergency department (ED) for evaluation and treatment. The predictor variable was the protocol used to identify injury etiology, that is, an innovative diagnostic protocol (DP) or the ED's standard operating procedure (SOP). The outcome variable was self-reported injury etiology categorized as IPV or other. Descriptive and bivariate statistics were Computed. Sensitivity, specificity, positive predictive value, negative predictive value, and odds ratios were Computed (with P <= .05 being considered statistically significant).
Results: The sample was composed of 286 women with a mean age of 45.8 years. The self-reported prevalence of IPV-related injuries was 11.5% and 5% for the DP and SOP, respectively (P = .03). The diagnostic statistics for the DP and SOP, respectively, were as follows: sensitivities, 94% and 50%; specificities, 76% and 95%; positive predictive values, 34% and 50%; and negative predictive values, 98% and 95%. In the adjusted model the women evaluated with the DP had a 38-fold increased likelihood of reporting IPV (P < .01) when compared with the SOP.
Conclusions: These results suggest that the proposed DP is associated with an increased frequency of self-reported IPV-related injuries when compared with the ED's SOP. (C) 2009 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 67:1453-1459, 2009

AB Knowledge of the morphology and kinematics of the male and female knees is important for understanding gender-related dimorphism in knee pathology and improvement of related surgical treatments. Twelve male and 12 female subjects with healthy knees were recruited, and each subject performed a single leg lunge while images of the knee were recorded by two fluoroscopes. Tibiolentoral joint, motion was then reproduced using bony models matched to the fluoroscopic images. Femoral trochlear groove orientation was also measured in each knee. While many of the measured parameters were Found to be similar between the genders, a few interesting differences were also noted. Females showed greater external tibial rotation at 0 degrees flexion (-5.4 degrees vs. -1.3, p = 0.03), smaller internal rotation at 30 degrees flexion (1.7 vs. 6.49 degrees, p = 0.04) and greater range of tibial rotation (18.2 degrees vs. 12.4 degrees, p = 0.01) compared to males. Female knees also had a more medially oriented proximal trochlear groove (10.0 degrees vs. 4.5 degrees, p = 0.04). These gender differences in rotational kinematics and trochlear groove orientation may warrant further studies to determine implications for Surgical treatments such as total knee arthroplasty, and gender-related dimorphism in certain knee injuries and pathologies, like anterior cruciate ligament injury and patellofemoral problems.

AB Although chronic obstructive pulmonary disease (COPD) is a highly prevalent and disabling illness, few empirical studies have evaluated the impact of the disease on symptom distress, functional status, and quality of life. These outcomes were explored in a prospective survey of 100 patients with advanced COPD. Patients were recruited from two academic centers. The mean forced expiratory volume in 1 second (EEV1) was 24.4% (standard deviation = 3.9). Validated instruments were used to assess symptom distress (Memorial Symptom Assessment Scale [MSAS]), mental health (Mental Health Inventory [MHI]-5), functional status (Sickness Impact Profile [SIPI), quality of life (Multidimensional Index of Life Quality [MILQ]), spirituality (Functional Assessment of Chronic Illness Therapy [FACIT] Spirituality Scale), and comorbid conditions (Charlson Comorbidity Index). The most prevalent symptoms were dyspnea (94%), fatigue (71%), xerostomia (60%), coughing (56%), and anxiety (51%). Other symptoms with high prevalence were drowsiness (47%), irritability (42%), feeling nervous (40%), and wheezing (40%). Significant pain was reported in about. one-third of patients. Patients reported relatively high levels of overall functional impairment (SIP median = 24.0) and modest impairment in overall quality of life (MILQ median = 52). Overall, psychological well-being was relatively unimpaired, (median = 24.5), and the comfort derived from faith was intact (FACIT median = 2.5). Impairment in quality of life was strongly associated with symptom distress (MSAS-GDI; r = -0.74, P < 0.001), functional impairment (SIP total; r = -0.59, P < 0.001), female sex (r = -0.26, P = 0.01), and poor psychological well-being (MHI-5; r = 0.68, P < 0.001). In multivariate analyses, poor quality of life was strongly correlated with higher total. symptom distress, sickness-related dysfunction, and lower levels of psychological well-being (R(2) = 0.66). In addition, two specific psychological symptoms-worrying and feeling irritable-were independently predictive of poor quality of life. Patients with advanced COPD have multiple distressing symptoms and a high prevalence of disturbances in mood, functional status, and quality of life. A focus on ameliorating prevalent physical symptoms and psychological distress may lead to an improvement in the overall quality of life in this patient population.

AB Genomic amplification of c-Jun and its upstream kinases have been implicated as a mechanism of progression from well-differentiated to dedifferentiated liposarcoma. To further define the role of c-Jun in liposarcoma progression, we performed immunohistochemistry for c-Jun and its activating kinase ASK1 on a series of liposarcomas (n = 81). We. correlated the results with fluorescence in situ hybridization to detect c-Jun amplification. We also derived new cell lines from dedifferentiated liposarcomas with c-Jun amplification. c-Jun protein is expressed in the majority of dedifferentiated liposarcomas (91%) and their well-differentiated components (59%), but only in the minority of pure well-differentiated liposarcomas (27%). When c-Jun is amplified in dedifferentiated liposarcoma, it is interspersed with amplified MDM2 on ring and giant marker chromosomes. MDM2 amplification is one of the earliest events in liposarcoma development, and these results suggest that c-Jun was amplified at a similar time in the evolution of the tumour. In addition, shRNA to c-Jun in c-Jun-amplified liposarcoma cells reduces cell number in vitro and inhibits tumour formation in vivo without an observable effect on the differentiation state of the liposarcoma cells. Thus, c-Jun amplification is oncogenic in liposarcomas but not always sufficient for inhibition of adipocytic differentiation. Copyright (C) 2009 Pathological Society of Great Britain and Ireland.

AB This report describes the corneal pathology in an infant with newborn primary congenital glaucoma and discusses whether these findings could be due to a developmental anomaly. The corneal specimen of a 4-month-old infant with newborn primary congenital glaucoma and cloudy corneas who had undergone penetrating keratoplasty was evaluated by light and electron microscopy. Light microscopy showed a thinned epithelium, areas of thickened Bowman's layer (approximately 27 pm thick) interspersed with nuclei, and a thickened and disorganized stroma. Descemet's membrane was intact, and the endothelium was mildly attenuated. The corneal changes seen in this patient may be specific to primary congenital glaucoma and may contribute to the corneal clouding seen so frequently in these patients.

AB Objective Predictive genetic testing for hereditary breast/ovarian cancer risk (BRCA1/2 testing) is not recommended for minor children due to its lack of immediate medical benefit and potential psychological risk. Yet, tested mothers are often interested in learning about their childrens cancer risks via pediatric BRCA1/2 testing, raising a host of bioethical concerns. However, no reliable or valid tool exists to formally gauge parents interest in such testing. The aim of this study was to develop and evaluate a new measure for use in genetic research and consultation, known as the Pediatric BRCA1/2 Testing Attitudes Scale (P-TAS). Methods After pretest genetic counseling and provision of a blood sample for BRCA1/2 testing, the P-TAS was administered to 187 mothers of children between 8- and 21-years-old. The measure was also given to 96 of the mothers nontested co-parents. Analyses of the factor structure and psychometric properties of the measure were performed in mothers and confirmed in their co-parents. Results The two factors of the P-TAS, labeled Attitudes and Beliefs (Factor 1) and Decision Making and Communication (Factor 2), accounted for 62.9 of the variance and were reliable (Cronbachs coefficient alpha s = .70 and.90, respectively); the structure and properties were largely confirmed among co-parents. Validity was indicated through its convergence with related constructs. Conclusions This new tool may be integrated into genetic counseling research to better assess parents attitudes and interests in pediatric BRCA1/2 testing. Such information may help guide ongoing discussions about the appropriateness of testing in adolescent or young adult children.

AB Background/Purpose: Congenital fourth branchial arch anomalies are uncommon entities, heretofore described only in case reports, affecting primarily children, and typically presenting as a cervical inflammatory process. The aim of the study was to collect appropriate data on the diagnosis, treatment, and outcome of this condition and to suggest guidelines for its management.
Methods: We conducted a structured review of the literature for cases explicitly identified as congenital fourth branchial arch anomalies or meeting anatomical criteria for this condition. We computed descriptive statistics and performed several post hoc 2-way comparisons of subgroups of cases.
Results: We located and critically evaluated 526 cases. Fourth arch anomalies were usually located on the left (94%) and generally presented as acute suppurative thyroiditis (45%) or recurrent neck abscess (42%). Barium swallow and direct laryngoscopy were the most useful diagnostic tools. Treatment options differed mainly in recurrence rates: incision and drainage, 89%. open neck surgery and tract excision, 15%; endoscopic cauterization of the sinus tract opening, 15%; and open neck surgery with partial thyroidectomy, 8%. Complications after surgery occurred primarily in children 8 years or younger.
Conclusion: Fourth arch anomalies are more common than once thought. Treatment of these disorders with repeated incision and drainage yields high rates of recurrence; thus, complete excision of the entire fistula tract during a quiescent period appears preferable. Combining this surgery with partial thyroidectomy may further decrease recurrence rates. Complications can likely be minimized by using antibiotic treatment of acute infections or endoscopic cauterization in children 8 years or younger, and delaying open neck surgery.

AB Objective To examine the effects of high doses of extended-release methylphenidate (OROS MPH) on cardiovascular variables in adolescents with attention deficit hyperactivity disorder (ADHD).
Study design ECG indices plus systolic blood pressure (SBP), diastolic BP (DBP) and heart rate (HR) were assessed during an open-label study of OROS MPH in 114 adolescents with ADHD (doses up to 1.5 mg/kg/d), Cardiovascular parameters were assessed at 6 weeks and 6 months.
Results Small but statistically significant changes in DBP and HR were observed at 6 weeks, without further increases up to 6 months' follow-up. A small but statistically significant increase in SBP was observed over time. Twenty-nine percent of patients had isolated elevations in BP readings prior to study entry, and 14% had > 3 consecutive visits at which elevated BP were observed during OROS MPH treatment. No clinically significant changes in ECG parameters were observed. No serious cardiovascular adverse events occurred.
Conclusions Treatment with relatively high doses of OROS MPH was associated with small but statistically significant mean increases in BP and HR, primarily during the first 6 weeks of treatment, without clinically meaningful changes in ECG. These observations are consistent with previous reports using lower doses. (J Pediatr 2009;155:84-9).

AB Background: Chronic oral infections that elicit host responses leading to periodontal disease are linked with various sequelae of systemic diseases. This report provides seminal information on the clinical and adaptive immunologic characteristics of a baboon model of ligature-induced periodontitis during pregnancy.
Methods: Female Papio anubis were evaluated for periodontal health at baseline. Ligatures were tied around selected teeth to initiate oral inflammation and periodontitis. Then the animals were bred. At midpregnancy (similar to 90 days), a clinical evaluation was performed, and additional ligatures were tied on teeth in the contralateral quadrants to maintain progressing periodontitis throughout pregnancy. A final clinical evaluation was done for all experimental teeth after delivery, and ligatures were removed. Serum was collected at all sampling intervals for the determination of antibody levels to a group of 20 oral bacteria. Unligated animals served as controls.
Results: At baseline, 16% of animals exhibited minimal plaque and gingival inflammation without periodontal disease. The remaining baboons demonstrated varying levels of inflammation/bleeding, and similar to 20% of the population had periodontal pocketing (>3 mm). Ligated animals expressed increased levels of inflammation and increased probing depths and clinical attachment loss (AL) and could be stratified into multiple subsets postligation based upon changes in clinical parameters at midpregnancy and at delivery. Baboons were categorized into disease susceptibility groups (periodontal disease susceptibility 1 through 4) that described the extent/severity of induced disease during pregnancy. Control animals showed minimal periodontal changes during gestation. Significant differences in serum antibody to multiple oral bacteria were found in animals presenting with periodontitis at baseline and during the 6 months of ligature-induced disease. A significant correlation to antibody to P. gingivalis, which was sustained throughout ligation and pregnancy, was observed with disease presentation.
Conclusions: The clinical presentation at baseline, reflecting the natural history of oral disease in these animals, suggests individual variation that is reflected in the characteristics of the adaptive immune responses to oral bacteria. The variability in the response to ligation with resulting periodontal disease provides a model to document prospectively the relationship between oral and systemic health outcomes.

AB Angiotensin II (AngII) initiates cellular effects via its G protein-coupled angiotensin 1 (AT(1)) receptor (AT(1)R). Previously, we showed that AngII-induced expression of the prostanoid-producing enzyme cyclooxygenase 2 (COX-2) was dependent upon nuclear trafficking of activated AT(1)R. In the present study, mastoparan (an activator of G proteins), suramin (an inhibitor of G proteins), 1-[6-[[17 beta-methoxyestra-1,3,5(10)-trien-17-yl]amino]hexyl]-1H-pyrrole-2,5-dione (U73122; a specific inhibitor of phospholipase C), and sarcosine(1)-Ile(4)-Ile(8)-AngII (SII-AngII; a G protein-independent AT(1)R agonist) were used to determine the involvement of G proteins and AT(1A)R trafficking in AngII-stimulated COX-2 protein expression in human embryonic kidney-293 cells stably expressing AT(1A)/green fluorescent protein receptors and cultured vascular smooth muscle cells, respectively. Mastoparan alone stimulated release of intracellular calcium and increased COX-2 expression. Preincubation with mastoparan inhibited AngII-induced calcium signaling without altering AngII-induced AT(1A)R trafficking, p42/44 extracellular signal-regulated kinase (ERK) activation, or COX-2 expression. Suramin or U73122 had no significant effect on their own; they did not inhibit AngII-induced AT(1A)R trafficking, p42/44 ERK activation, or COX-2 expression; but they did inhibit AngII-induced calcium responses. SII-AngII stimulated AT(1A)R trafficking and increased COX-2 protein expression without activating intracellular calcium release. These data suggest that G protein activation results in increased COX-2 protein expression, but AngII-induced COX-2 expression seems to occur independently of G protein activation.

AB Alternatives to the canonical insulin-stimulated pathway for glucose uptake are exercise- and exogenous reactive oxygen species (ROS)-stimulated glucose uptake. We proposed a model wherein mechanical loading, i.e. stretch, stimulates production of ROS to activate AMP-activated kinase (AMPK) to increase glucose uptake. Immunoblotting was used to measure protein phosphorylation; the fluorochrome probe 2'7'-dichlorofluorescin diacetate was used to measure cytosolic oxidant activity and 2-deoxy-d[1,2-(3)H]glucose was used to measure glucose uptake. The current studies demonstrate that stretch increases ROS, AMPK alpha phosphorylation and glucose transport in murine extensor digitorum longus (EDL) muscle (+121%, +164% and +184%, respectively; P < 0.05). We also demonstrate that stretch-induced glucose uptake persists in transgenic mice expressing an inactive form of the AMPK alpha 2 catalytic subunit in skeletal muscle (+173%; P < 0.05). MnTBAP, a superoxide dismutase (SOD) mimetic, N-acteyl cysteine (NAC), a non-specific antioxidant, ebselen, a glutathione mimetic, or combined SOD plus catalase (ROS-selective scavengers) all decrease stretch-stimulated glucose uptake (P < 0.05) without changing basal uptake (P > 0.16). We also demonstrate that stretch-stimulated glucose uptake persists in the presence of the phosphatidylinositol 3-kinase (PI3-K) inhibitors wortmannin and LY294001 (P < 0.05) but is diminished by the p38-MAPK inhibitors SB203580 and A304000 (P > 0.99). These data indicate that stretch-stimulated glucose uptake in skeletal muscle is mediated by a ROS- and p38 MAPK-dependent mechanism that appears to be AMPK alpha 2- and PI3-K-independent.

AB Objective. The goal of this study was to evaluate which anthropometric measure (human body measurement) best predicts insulin resistance measured by the insulin sensitivity index (SI) and the homeostasis model of assessment of insulin resistance (HOMA-IR) in nondiabetic patients with schizophrenia treated with clozapine or olanzapine. Methods. We conducted a cross-sectional study of nondiabetic subjects with schizophrenia being treated with olanzapine or clozapine using a frequently sampled intravenous glucose tolerance test, nutritional assessment, and anthropometric measures, to assess the relationship between anthropometric measures and insulin resistance. Results. No difference was found between the groups treated with clozapine and olanzapine in age, gender, race, body mass index (BMI), waist circumference (WC), lipid levels, HOMA-IR, or SI. The disposition index (SI x the acute insulin response to glucose), which measures how the body compensates for insulin resistance to maintain a normal glucose level, was significantly lower in the group treated with clozapine than in the group treated with olanzapine (1067 1390 vs. 2521 2805; p = 0.013), suggesting that the subjects treated with clozapine had a reduced compensatory response to IR compared with the subjects treated with olanzapine. In the clozapine group, both higher WC and BMI were significantly associated with elevated HOMA-IR and lower SI; however, WC was a stronger correlate of IR than BMI, as measured by SI (-0.50 vs. -0.40). In the olanzapine group, neither WC nor BMI was significantly associated with any measure of glucose metabolism. Conclusions. In this study, WC was the single best anthropometric surrogate for predicting IR in patients treated with clozapine but not olanzapine. The results suggest that WC may be a valuable screening tool for predicting IR in patients with schizophrenia being treated with clozapine who are at relatively higher risk of developing the metabolic syndrome, type 2 diabetes mellitus, and associated cardiovascular disease.

AB Background: Brain-derived neurotrophic factor (BDNF) mutant mice show hyperphagia and hyperleptinemia. Animal and cell-culture experiments suggest multiple interrelations between BDNF and the serotonin (5-HT) system. We studied serum BDNF in patients with anorexia nervosa and its associations with peripheral indicators of the 5-HT system. To control for secondary effects of acute malnutrition, we assessed acutely underweight patients with anorexia nervosa (acAN) in comparison to long-term weight-recovered patients with the disorder (recAN) and healthy controls. Methods: We determined serum BDNF, platelet 5-HT content and platelet 5-HT uptake in 33 patients in the acAN group, 20 patients in the recAN group and 33 controls. Plasma leptin served as an indicator of malnutrition. Results: Patients in the acAN group were aged 14-29 years and had a mean body mass index (BMI) of 14.9 (standard deviation [SD] 1.4) kg/m(2). Those in the recAN group were aged 15-29 years and had a mean BMI of 20.5 (SD 1.3) kg/m(2) and the controls were aged 15-26 years and had a BMI of 21.4 (SD 2.1) kg/m(2). The mean serum BDNF levels were significantly increased in the recAN group compared with the acAN group (8820, SD 3074 v. 6161, SD 2885 pg/mL, U= 154.5, p = 0.001). There were no significant associations between BDNF and either platelet 5-HT content or platelet 5-HT uptake. Among patients with anorexia nervosa, we found significant positive linear relations between BDNF and BMI (r = 0.312, p = 0.023) and between BDNF and leptin (r = 0.365, p = 0.016). Limitations: We measured the signal proteins under study in peripheral blood. Conclusion: Serum BDNF levels in patients with anorexia nervosa depend on the state of illness and the degree of hypoleptinemia. Upregulation of BDNF in weight-recovered patients with anorexia nervosa could be part of a regenerative process after biochemical and molecular neuronal injury due to prolonged malnutrition. Associations between the BDNF and the 5-HT system in humans remain to be established.

AB Objective. To assess the effect Of golimumab (human monoclonal antibody to tumor necrosis factor-alpha) plus methotrexate (MTX) on selected inflammatory biomarkers, and to determine if these effects predict clinical response in rheumatoid arthritis (RA).
Methods. Sera from adults with active RA despite MTX therapy. who received subcutaneous injections of placebo + MTX (MTX alone, n = 34) or golimumab 50 or 100 mg every 2 or 4 weeks + MTX (n = 137). were analyzed for levels of C-reactive protein (CRP), Serum amyloid A (SAA), interleukin 18 (IL-18). E-selectin, matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of matrix metalloproteinase I (TIMP-I).
Results. Golimumab + MTX treatment significantly decreased serum CRP SAA. IL-18, E-selectin, TIMP-1, and MMP-9 levels (median percent changes of -4.1% to -74.3% across treatment groups) versus MTX alone (-5.8% to 9.7%) when first measured at Week 4: decreases were sustained through Week 16. Larger magnitudes of decrease in all biomarkers were observed for clinical responders Versus nonresponders. For golimumab + MTX. regression analyses including all biomarkers and select clinical measures showed that reductions ill levels of several markers (SAA, E-selectin, MMP-9) as early as Week 4 correlated significantly with improvement in swollen joint Count (SJC) at Week 16, as did reductions in E-selectin with improvement in tender joint count at Week 16. After accounting for the biomarkers, however, treatment group was no longer significant for SJC.
Conclusion. Significant decreases in several inflammatory biomarkers were associated with golimumab + MTX therapy. Decreases in serum levels of SAA, E-selectin. and MMP-9 Lit Week 4 may be useful in predicting clinical response at Week 16.

AB Introduction.
A strong association between cardiovascular risk factors and erectile dysfunction (ED) was suggested. Coronary artery bypass grafting (CABG) is the gold standard for surgical myocardial revascularization.
Aim.
We herein evaluate the impact of vascular risk factors on postoperative sexual functions in patients undergo CABG.
Main Outcome Measures.
ED severity by the International Index of Erectile Function (IIEF-5) and penile duplex study.
Methods.
The present study included 100 patients who underwent CABG. The patients were evaluated by an abridged form of the IIEF-5 questionnaire, followed by CABG. Six months after surgery the erectile function of all patients was revaluated utilizing the IIEF-5.
Results.
Number of risk factors was significantly associated with postoperative change in IIEF-5 score (P = 0.02). A post hoc analysis of the association revealed that patients with one risk factor were significantly more likely to have increased IIEF-5 scores (N = 18), whereas those with two or more risk factors were significantly more likely to have decreased IIEF-5 scores (N = 21, P < 0.05). Furthermore, those with no risk factors were significantly more likely to be stable (N = 8) compared with those with more than two risk factors, who were more likely to have decreased scores (P < 0.05). The hierarchical logistic regression results showed that when examining all risk factors simultaneously, because of multicollinearity, only hyperlipidemia was significantly associated with postoperative ED (odds ratio [OR] = 11.33, confirdence interval [CI] = 1.25, 102.82). Frequency of intercourse was also significantly associated with postoperative ED after controlling for risk factors (OR = 0.71, CI = 0.52, 0.97).
Conclusions.
This data clearly shows that the number of cardiovascular risk factors is an essential predictive factor for sexual function following surgery. Only hyperlipidemia may play a predictive role for the future sexual function of patients undergo CABG. Mohamed OA, Hamed HA, Roaiah MF, Helmy T, Mahran A, and Bennett CJ.

CANDIDATE GENES; BIRTH-WEIGHT; CHILDREN; SEROTONIN; CHILDHOOD
AB Objective: Recent studies have suggested an association between candidate genes (i.e., COMT, SLC6A4) and conduct disorder (CD). However, it is not clear if these relations extend to CD within the context of attention-deficit/hyperactivity disorder (ADHD). Also, it is uncertain whether the risk is specific to aggressive symptoms or is a risk for CD generally. The aim of this study was to examine the role of the COMT and SLC6A4 genes in the risk for CD and its symptomatic subtypes in the context of ADHD. Method: We examined subjects with ADHD (n = 444, age range 6-55 years) aggregated across four completed studies. Psychiatric diagnoses were determined by structured interviews. We tested the association between genotype and the diagnosis of CD and aggressive and covert symptom counts. Results: There was no significant association between variations in functional polymorphisms of either the COMT gene or the SLC6A4 gene and the risk for CD. The COMT gene was associated with increased aggressive CD symptoms but not covert CD symptoms. The SLC6A4 gene was not associated with either symptom subtype. Conclusions: These findings contribute to our understanding of the genetic basis of antisocial behavior in the ADHD population and provide additional support for the notion that aggressive and covert CD symptom subtypes are etiologically distinct.

AB Objective: We examined the association between statin use and basal cell carcinoma (BCC) risk.
Methods: We identified all members of a large integrated health care delivery system with a diagnosis of a histologically proven BCC in 1997. Subsequent BCCs were identified through 2006 from health plan electronic pathology records. Longitudinal exposure to statins and other lipid-lowering agents was determined from automated pharmacy records. We used extended Cox regression to examine the independent association between receipt of statin therapy (ever vs never, cumulative duration) and risk of subsequent BCC. To minimize confounding by indication, we conducted sensitivity analyses in the subset of individuals considered eligible for lipid-lowering therapy based on national guidelines.
Results: Among 12,123 members given a diagnosis of BCC who had no prior statin exposure, 6381 developed a subsequent BCC during follow-up. Neither "ever use of statins" (adjusted hazard ratio 1.02, 95% confidence interval: 0.92-1.12) or Cumulative duration of statin (adjusted hazard ratio 1.02/year, 95% confidence interval: 0.99-1.11) was associated With subsequent BCC after adjustment for age, sex, and health care use. Risk estimates did not change appreciably when the analysis was limited to the Subset of individuals who met eligibility criteria for initiating statin therapy. There was also no significant association between use of non-statin antilipemics and subsequent BCC (adjusted hazard ratio 1.10, 95% confidence interval: 0.76-1-58).
Limitations: No information was available for BCC risk factors, Such as sun sensitivity and sun exposure.
Conclusions: Among a large cohort of individuals with BCC, statin therapy was not significantly associated with risk of subsequent BCC. (J Am Acad Dermatol 2009;61:66-72.)

TI Acquired bilateral nevus of Ota-like macules (Hori nevus): Etiologic and
therapeutic considerations
SO JOURNAL OF THE AMERICAN ACADEMY OF DERMATOLOGY

DT Review
ID SWITCHED RUBY-LASER; ND-YAG LASER; DERMAL MELANOCYTOSIS; ALEXANDRITE
LASER; COMBINATION
AB Background: Acquired bilateral nevus Of Ota-like macules (ABNOM), also known as Hori nevus, is one of the most commonly acquired dermal facial melanocytoses among people with dark skin, especially Asian women.
Objective: The goals of this article were to review published work on ABNOM; address controversies about pathogenesis and therapeutic approach; and inspire further study.
Methods: Articles in the literature related to the description of ABNOM were extracted and summarized.
Results: Clinically, ABNOM occurs predominantly on the face of middle-aged women. Histologically, it is characterized by irregularly shaped, bipolar melanocytes dispersed through the mid to papillary dermis. Therapeutically, various pigment-targeting lasers have emerged as the major mode of treatment.
Limitations: There is a notable absence of both biological insight into the cause of ABNOM and robust trials to effectively define a standardized therapy. The scattered reports in the literature preclude a more rigorous meta-analytical approach.
Conclusion: Although there have been many reports on ABNOM since 1984, the pathogenesis still remains unclear and controversial, and treatment of ABNOM is still challenging. (J Am Acad Dermatol 2009;61:88-93.)

LA English
DT Article
ID UNITED-STATES; MRSA
AB Purpose: To examine skin and soft tissue infections presenting at 4 primary care clinics and assess if historical risk factors and examination findings were associated with a positive methicillin-resistant Staphylococcus aureus (MRSA) culture.
Methods: During the 10-month observational study (April 2007 through January 2008), physicians in 5 practices across South Texas collected history, physical examination findings, culture results, and antibiotic( s) prescribed for all patients presenting with a skin or soft tissue infection. Analyses were conducted to determine the relationship between historical indicators, location of lesions, and examination findings with a positive MRSA culture.
Results: Across 4 practices, 164 cases of skin and soft tissue infections were collected during 10 months. Of the 94 with a culture, 63 (67%) were MRSA positive. Patients working in or exposed to a health care setting were more likely to have a culture positive for MRSA, as were those presenting with an abscess. MRSA-positive lesions were also significantly smaller in size.
Conclusions: Because of the high prevalence of MRSA skin and soft tissue infections among patients presenting to family physicians, presumptive treatment for MRSA may be indicated. However, increasing levels of resistance to current antibiotics is concerning and warrants development of alternative management strategies. (J Am Board Fam Med 2009;22:375-9.)

AB BACKGROUND: Hypothermia increases the tolerable ischemia time for myocardium in hemorrhagic shock, but precise mechanisms are not clearly established. Here we studied activation of Akt cell survival pathway in a rodent model of emergency preservation and delayed resuscitation.
STUDY DESIGN: Wistar-Kyoto rats underwent 40% blood volume arterial hemorrhage during 10 minutes and were randomized into 2 groups based on core body temperatures (n = 7/group): hypothermia (15 degrees C) and normothermia (37 degrees C). Hypothermia was induced by infusing cold isotonic solution using cardiopulmonary bypass (CPB) setup. After reaching target body temperature, low-flow state (CPB flow rate of 20 mL/kg/min) was maintained for 60 minutes. Hypothermic rats were rewarmed to baseline temperature; all rats were resuscitated on CPB and monitored for 3 hours. The normothermia group underwent identical CPB management. Sham rats (no hemorrhage, no instrumentation) were used as controls (n = 7). Tissues were harvested at the end of experiment.
RESULTS: Induction of hypothermia increased survival rates (100% versus 0% in normothermia group). Western blot analysis of cardiac tissue revealed increased levels of phospho-Akt (active) in hypothermia and sham groups compared with the normothermia group (p < 0.05). Among downstream targets of Akt, phospho-GSK-3 beta (inactive), phospho-Bad (inactive), beta-catenin, and Bcl-2 were considerably elevated in the hypothermia group compared with the normothermia group. Hypothermia also showed decreased activity of caspase-3 protein compared with normothermia (p < 0.05), suggesting decreased apoptosis.
CONCLUSIONS: Profound hypothermia increases survival in a rodent model of hemorrhagic shock and prolonged low-flow state. Hypothermia preserves Akt signaling pathway in cardiomyocytes with a concurrent decrease in cardiac apoptosis. (J Am Coll Surg 2009;209:89-99. (C) 2009 by the American College of Surgeons)

AB Residents in nursing homes (NHs) experience pain that is underrecognized and undertreated. This pain contributes to a decline in quality of life. Although descriptive studies of pain assessment and management have been conducted, few have been published that critically evaluate interventions to improve pain management. Identification of the strengths and gaps in the current literature is required. A literature search was conducted of clinical trials that evaluated prospective interventions to improve pain management. Information on the intervention type, resident sample and setting, endpoints, and study design were extracted. Studies were classified based on a modification of Donabedian's model of healthcare quality. Four categories of interventions were identified: actor, decision support, treatment, and systems. The search strategy and selection criteria yielded 21 articles. Eleven studies used an actor intervention; of these, eight also employed a systems intervention, and one also used a treatment intervention. Two studies used a decision support intervention, seven used a treatment intervention, and one used a systems intervention. The overall quality of research was uneven in several areas: research design-nine studies were quasi-experimental in nature, endpoints measures were not consistent-three did not perform statistical analysis, and characteristics of the resident samples varied dramatically. In conclusion, the number of high-quality studies of pain management in NHs remains limited. Process endpoints are used as surrogate measures for resident endpoints. Systematic approaches are needed to understand how each type of intervention improves the quality of pain management at the resident level.

AB Despite increasing numbers of geriatric prisoners, little is known about geriatric disability or health care in prison. Although correctional officers often act as a liaison between prisoners and the healthcare system, the role of officers in recognizing geriatric disability has not been characterized. The goals of this study were to assess officers' assessment of disability in their assigned geriatric prisoners and to contrast their views with reports from the California Department of Corrections and Rehabilitation (CDCR). Questionnaires were given to 71 officers assigned to 618 randomly selected geriatric prisoners in 11 prisons. Information about 41 additional prisoners identified by correctional officers as "high risk" was also analyzed. Prisoner disability and health were determined through correctional officer questionnaires (activity of daily living (ADL) impairment, geriatric syndromes, level of care), chart review (medical diagnoses), and CDCR data (demographics, disability designation). Overall, 211 (34.1%) geriatric prisoners were unknown to their officer. Of the 407 known prisoners, officers reported that 5.0% had ADL impairment and 3.1% were unsafe. Discordance between officer and CDCR reports of disability was common, with officers reporting higher disability rates. The 41 high-risk prisoners were more likely to have ADL impairment (22.0% vs 5.2%, P <.01) and geriatric syndromes such as falls and incontinence than the random sample. Overall, nearly one-third of geriatric prisoners were unknown to their assigned officer. Officers identified more disability than the CDCR, and prisoners they identified as high risk had nursing home-level functional impairments. Significant improvement in disability assessment is needed for officers and the CDCR.

Apathy is associated with a number of adverse outcomes, including apparent cognitive impairment, decreased daily function, poor insight into one's own functional and cognitive impairment, and poor outcome from rehabilitation treatment. Furthermore, the degree of caregiver's burden in these patients is significant. This article reviews the definition of apathy, prevalence and associated adverse outcomes, causation, the approach to patients with apathy, and available treatment options with particular attention to studies conducted in a nursing home setting. The purpose of this article is to increase the recognition of apathy by physicians working in the nursing home. (J Am Med Dir Assoc 2009; 10: 381-393)

AB Context: Telemedicine is a promising but largely unproven technology for providing case management services to patients with chronic conditions and lower access to care.
Objectives: To examine the effectiveness of a telemedicine intervention to achieve clinical management goals in older, ethnically diverse, medically underserved patients with diabetes.
Design, Setting, and Patients: A randomized controlled trial was conducted, comparing telemedicine case management to usual care, with blinded outcome evaluation, in 1,665 Medicare recipients with diabetes, aged 55 years, residing in federally designated medically underserved areas of New York State.
Interventions: Home telemedicine unit with nurse case management versus usual care.
Main Outcome Measures: The primary endpoints assessed over 5 years of follow-up were hemoglobin A1c (HgbA1c), low density lipoprotein (LDL) cholesterol, and blood pressure levels.
Results: Intention-to-treat mixed models showed that telemedicine achieved net overall reductions over five years of follow-up in the primary endpoints (HgbA1c, p = 0.001; LDL, p < 0.001; systolic and diastolic blood pressure, p = 0.024; p < 0.001). Estimated differences (95% CI) in year 5 were 0.29 (0.12, 0.46)% for HgbA1c, 3.84 (-0.08, 7.77) mg/dL for LDL cholesterol, and 4.32 (1.93, 6.72) mm Hg for systolic and 2.64 (1.53, 3,74) mm Hg for diastolic blood pressure. There were 176 deaths in the intervention group and 169 in the usual care group (hazard ratio 1.01 [0.82, 1.24]).
Conclusions: Telemedicine case management resulted in net improvements in HgbA1c, LDL-cholesterol and blood pressure levels over 5 years in medically underserved Medicare beneficiaries. Mortality was not different between the groups, although power was limited.

AB Objective: To compare the experiences of e-prescribing users and nonusers regarding prescription safety and workload and to assess the use of information from two e-prescribing standards (for medication history and formulary and benefit information), as they are implemented.
Design: Cross-sectional survey of physicians who either had installed or were awaiting installation of one of two commercial e-prescribing systems.
Measurements: Perceptions about medication history and formulary and benefit information among all respondents, and among e-prescribing users, experiences with system usability, job performance impact, and amount of e-prescribing.
Results: Of 395 eligible physicians, 228 (58%) completed the survey. E-prescribers (n = 139) were more likely than non-e-prescribers (n = 89) to perceive that they could identify clinically important drug-drug interactions (83 versus 67%, p = 0.004) but not that they could identify prescriptions from other providers (65 versus 60%, p = 0.49). They also perceived no significant difference in calls about drug coverage problems (76 versus 71% reported getting 10 or fewer such calls per week; p = 0.43). Most e-prescribers reported high satisfaction with their systems, but 17% had stopped using the system and another 46% said they sometimes reverted to handwriting for prescriptions that they could write electronically. The volume of e-prescribing was correlated with perceptions that it enhanced job performance, whereas quitting was associated with perceptions of poor usability.
Conclusions: E-prescribing users reported patient safety benefits but they did not perceive the enhanced benefits expected from using standardized medication history or formulary and benefit information. Additional work is needed for these standards to have the desired effects.

AB Objective: The authors previously implemented an electronic heart failure registry at a large academic hospital to identify heart failure patients and to connect these patients with appropriate discharge services. Despite significant improvements in patient identification and connection rates, time to connection remained high, with an average delay of 3.2 days from the time patients were admitted to the time connections were made. Our objective for this current study was to determine the most effective solution to minimize time to connection.
Design: We used a queuing theory model to simulate 3 different potential solutions to decrease the delay from patient identification to connection with discharge services.
Measurements: The measures included average rate at which patients were being connected to the post discharge heart failure services program, average number of patients in line, and average patient waiting time.
Results: Using queuing theory model simulations, we were able to estimate for our current system the minimum rate at which patients need to be connected (262 patients/mo), the ideal patient arrival rate (174 patients/mo) and the maximal patient arrival rate that could be achieved by adding 1 extra nurse (348 patients/mo).
Conclusions: Our modeling approach was instrumental in helping us characterize key process parameters and estimate the impact of adding staff on the time between identifying patients with heart failure and connecting them with appropriate discharge services.

AB Acute renal ischemia elicits an inflammatory response that may exacerbate acute kidney injury, but the regulation of the initial signals that recruit leukocytes is not well understood. Here, we found that IFN regulatory factor 1 (IRF-1) was a critical, early proinflammatory signal released during ischemic injury in vitro and in vivo. Within 15 min of reperfusion, proximal tubular cells of the S3 segment produced IRF-1, which is a transcription factor that activates proinflammatory genes. Transgenic knockout of IRF-1 ameliorated the impairment of renal function, morphologic injury, and inflammation after acute ischemia. Bone marrow chimera experiments determined that maximal ischemic injury required IRF-1 expression by both leukocytes and radioresistant renal cells, the latter identified as S3 proximal tubule cells in the outer medulla by in situ hybridization and immunohistochemistry. In vitro, reactive oxygen species, generated during ischemia/reperfusion injury, stimulated expression of IRF-1 in an S3 proximal tubular cell line. Taken together, these data suggest that IRF-1 gene activation by reactive oxygen species is an early signal that promotes inflammation after ischemic renal injury.

AB Uniaxial mechanical experiments have shown that a neo-Hookean/Gaussian model is suitable to describe the mechanics of arterial elastin networks [Gundiah, N., Ratcliffe, M.B., Pruitt, L.A., 2007. Determination of strain energy function for arterial elastin: Experiments using histology and mechanical tests. J. Biomech. 40, 586-594]. Based on the three-dimensional elastin architecture in arteries, we have proposed an orthotropic material symmetry for arterial elastin consisting of two orthogonally oriented and symmetrically placed families of mechanically equivalent fibers. In this study, we use these results to describe the strain energy function for arterial elastin, with dependence on a reduced subclass of invariants, as W = W(I(1), I(4)). We use previously published equations for this dependence [Humphrey, J.D., Strumpf, R.K., Yin, F.C.P., 1990a. Determination of a constitutive relation for passive myocardium: I. A new functional form. J. Biomech. Eng. 112, 333-339], in combination with a theoretical guided Rivlin-Saunders framework [Rivlin, R.S., Saunders, D.W, 1951. Large elastic deformations of isotropic materials VII. Experiments on the deformation of rubber. Phil. Trans. R. Soc. A 243, 251-288] and biaxial mechanical experiments, to obtain the form of this dependence. Using mechanical equivalence of elastin in the circumferential and longitudinal directions, we add a term in 16 to W that is similar to the form in 14. We propose a semi-empirical model for arterial elastin given by W = c(0) (I(1) - 3) + c(1) (I(4) - 1)(2) + c(2) (I(6) - 1)(2), where c(0), c(1) and c(3) are unknown coefficients. we used the Levenberg-Marquardt algorithm to fit theoretically calculated and experimentally determined stresses from equibiaxial experiments on autoclaved elastin tissues and obtain c(0) = 73.96 +/- 22.51 kPa, c(1) = 1.18 +/- 1.79 kPa and c(2) = 0.8 +/- 1.26 kPa. Thus, the entropic contribution to the strain energy function, represented by c(0), is a dominant feature of elastin mechanics. Because there are no significant differences in the coefficients corresponding to invariants 14 and 16, we surmise that there is an equal distribution of fibers in the circumferential and axial directions.

AB Introduction: For the identification of the patients who most likely benefit from epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors in non-small cell lung cancer (NSCLC), molecular assays are considered to be of paramount importance. Given the heterogeneity of NSCLC at the molecular level, this study was conducted to determine the discrepancy in EGFR mutations between primary tumors and the corresponding lymph node metastasis.
Patients and Methods: Surgically resected 101 paired primary NSCLC and metastatic lymph nodes were evaluated for the EGFR mutations by direct DNA sequencing and heteroduplex analysis.
Results: EGFR mutation was detected in 29.7% (30 of 101) of the primary tumors and in 27.7% of lymph node metastases (28 of 101) by either direct sequencing or heteroduplex analysis, respectively. By direct sequencing, 12 cases (11.9%) showed discordance in EGFR mutations between primary tumors and metastasis. In 11 cases, EGFR mutations were detected only in the primary tumor, whereas 1 case only in lymph node metastases. By heteroduplex analysis, 17 cases (16.8%) were discordant. Ten cases were primary tumor positive and lymph node negative, whereas seven cases were lymph node positive and primary tumor negative.
Conclusions: A considerable proportion of NSCLC showed discrepancy in EGFR Mutations between primary tumors and metastatic lymph nodes, suggesting tumor heterogeneity at the molecular level during the process of metastasis.

AB Megakaryocyte (MK) maturation culminates in release of blood platelets through proplatelet extensions. MKs presumably delay elaborating proplatelets until synthesis of platelet constituents is complete. Recent insights from investigation of a classic human congenital macrothrombocytopenia, the May-Hegglin anomaly, and related MYH9-associated disorders shed new light on underlying mechanisms. The findings reviewed in this article implicate myosin IIA, the nonmuscle myosin heavy chain product of the MYH9 gene, in restraining proplatelet formation until MKs achieve terminal maturity. Loss of myosin IIA function, through dominant inhibitory mutations in humans, targeted gene disruption in mice, or manipulation of cultured MKs, seems to accelerate proplatelet formation. The resulting process is inefficient and produces platelets that vary widely in size, shape and content. Several lines of evidence suggest that the Rho-ROCK-myosin light chain pathway restrains proplatelet formation through myosin IIA. These findings illustrate that mammalian thrombopoiesis is complex and subject to both positive and negative regulation.

DISEASE; VWF
AB Background: von Willebrand factor (VWF) has a role in both hemostasis and thrombosis. Platelets adhere to damaged arteries by interactions between the VWF A1-domain and glycoprotein Ib receptors under conditions of high shear. This initial platelet binding event stimulates platelet activation, recruitment, and activation of the clotting cascade, promoting thrombus formation. Objective: To characterize the inhibitory activity of a VWF inhibitory aptamer. Methods: Using in vitro selection, aptamer stabilization, and conjugation to a 20-kDa poly(ethylene glycol), we generated a nuclease-resistant aptamer, ARC1779, that binds to the VWF A1-domain with high affinity (K(D) similar to 2 nm). The aptamer was assessed for inhibition of VWF-induced platelet aggregation. In vitro inhibition of platelet adhesion was assessed on collagen-coated slides and injured pig aortic segments. In vivo activity was assessed in a cynomolgus monkey carotid electrical injury thrombosis model. Results and Conclusion: ARC1779 inhibited botrocetin-induced platelet aggregation (IC(90) similar to 300 nm) and shear force-induced platelet aggregation (IC(95) similar to 400 nm). It reduced adhesion of platelets to collagen-coated matrices and formation of platelet thrombi on denuded porcine arteries. ARC1779 also inhibited the formation of occlusive thrombi in cynomolgus monkeys. We have discovered a novel anti-VWF aptamer that could have therapeutic use as an anti-VWF agent in the setting of VWF-mediated thrombosis.

AB Background: Peripheral serotonin (5-hydroxytryptamine, 5-HT) is transported by platelets and released upon stimulation. In the platelet cytoplasm, 5-HT is transamidated to small GTPases, promoting alpha-granule release and primary hemostasis. Objective: We hypothesized that 5-HT could also stimulate platelet receptor shedding after binding to the membrane 5-HT receptor (5-HT2AR). Methods: Western blot and flow cytometry were used to determine levels of the adhesion receptor glycoprotein (GP)Ib alpha on platelets or its shed fragment glycocalicin in plasma and serum from wild-type mice, Tph1(-/-) mice lacking peripheral 5-HT, and mice lacking functional tumor necrosis factor-alpha-converting enzyme (TACE, ADAM17). Flow chamber experiments and intravital microscopy were used to examine the adhesive properties of platelets after stimulation of 5-HT2AR. Results: Glycocalicin was significantly reduced in Tph1(-/-) plasma and serum. In isolated platelets, 5-HT induced shedding of GPIb alpha, which was increased to 60% when 5-HT uptake was inhibited by the selective serotonin reuptake inhibitor fluoxetine. Specific 5-HT2AR agonism and antagonism suggested activation of this receptor. The shedding could not be induced in TACE(Delta Zn/Delta Zn) platelets, suggesting that activated TACE mediated the shedding of GPIb alpha. Intracellular signaling involved phosphorylation of p38 mitogen-activated protein kinase rather than G-protein signaling. 5-HT2AR stimulation decreased platelet adhesion to collagen-bound von Willebrand factor under arterial shear (1500 s(-1)) and incorporation into FeCl(3)-induced thrombi in mesenteric arterioles. Conclusions: Stimulation of 5-HT2AR on platelets induces TACE-mediated shedding of GPIb alpha, the key adhesion molecule under high shear conditions. Our observations demonstrate a new pathway through which 5-HT could modulate cardiovascular disease.

AB We retrospectively evaluated dosing patterns and 37-day outcomes in argatroban-treated African American (n = 52), Asian (n = 13), and Hispanic (n = 14) patients with heparin-induced thrombocytopenia (HIT). The Asians required a lesser median dose (1.0 mu g/kg/min) than the other groups (1.9 mu g/kg/min, each) to achieve comparable activated partial thromboplastin times (medians: 61-69 s). Durations of therapy were similar (medians: 4.0-5.5 days). New thrombosis occurred in 11 (21%) African Americans, 1 (8%) Asian, and 1 (7%) Hispanic; of these 13 patients, 9 (69%) had baseline HIT-related thrombosis. Amputation occurred in 6 (12%) African Americans and 3 (21%) Hispanics; of these nine patients, 6 (67%) had diabetes. One (2%) African American and 1 (7%) Hispanic died from thrombosis. The composite of death due to thrombosis, amputation due to ischemic complications of HIT, or new thrombosis occurred in 14 (27%) African Americans, 1 (8%) Asian, and 4 (29%) Hispanics. Two (4%) African Americans and none others (0%) had major bleeding. These findings suggest that despite argatroban anticoagulation, African Americans and Hispanics may have worse outcomes in HIT than Asians. In minority patients with adverse HIT outcomes, baseline HIT-related thrombosis or diabetes is often present.

AB Cartilage tissue can be engineered by starting from a diversity of cell sources, including stem-cell based and primary cell-based platforms. Selecting an appropriate cell source for the process of cartilage tissue engineering or repair is critical and challenging, due to the variety of cell options available. in this study, cellular responses of isolated human chondrocytes, human embryonic stem cells and mesenchymal stem cells (MSCs) derived from three sources, human embryonic stem cells, bone marrow and adipose tissue, were assessed for chondrogenic potential in 3D culture. All cell sources were characterized by FACS analysis to compare expression of some surface markers. The cells were differentiated in two different biomaterial matrices, silk and chitosan scaffolds, in the presence and absence of bone morphogenetic protein 6 (BMP6), along with the standard chondrogenic differentiating factors. Embryonic stem cells-derived MSCs showed unique characteristics, with preserved chondrogenic phenotype in both scaffolds with regard to chondrogenesis, as determined by real time RT-PCR, histological and microscopical analyses. After 4 weeks of cultivation, embryonic stem cells-derived MSCs were promising for chondrogenesis, particularly in the silk scaffolds with BMP6. The results suggest that cell source differences are important to consider with regard to chondrogenic outcomes, and among the variables addressed here the human embryonic stem cells-derived MSCs were the preferred cell source.

TI The Long-Term Outcome of Open Reduction and Internal Fixation of Stable
Displaced Isolated Partial Articular Fractures of the Radial Head
SO JOURNAL OF TRAUMA-INJURY INFECTION AND CRITICAL CARE
LA English

ID MASON TYPE-II; FOLLOW-UP; NECK; ELBOW
AB Background: Excellent long-term results have been reported for nonoperative treatment of stable isolated displaced partial articular (Mason 2) fractures of the radial head, suggesting that the role of operative treatment can be questioned. This investigation reports the long-term outcome of operatively treated Mason 2 radial head fractures.
Methods: Sixteen patients with stable displaced partial articular (Mason 2) fractures of the radial head not associated with fracture or dislocation of the proximal forearm were evaluated an average of 22 years (range, 14-30 years) after open reduction and internal fixation with screws (I I patients) or a plate and screws (5 patients). Complications included two infections (I deep and I superficial), two patients with restriction of motion because of screws of excessive length, and one transient posterior interosseous nerve palsy. A second surgery for implant removal was routine (14 of 16 patients).
Results: The average flexion arc was 129 degrees (range, 110-145 degrees) and the average forearm rotation arc was 166 degrees (range, 120-180 degrees). According to the Mayo Elbow Performance Index, elbow function was excellent in nine patients, good in four, fair in two, and poor in one patient. According to the classification system of Steinberg et al., there were three good, eight fair, and five poor results. The average score on the Disabilities of the Arm, Shoulder, and Hand questionnaire was 12 points (range, 0-52).
Conclusion: The long-term results of operative treatment of stable isolated displaced partial articular (Mason 2) fractures of the radial head demonstrate no appreciable advantage over the long-term results of nonoperative treatment of these fractures published in prior reports. Moreover, the appeal of operative treatment is diminished by the potential complications.
