AB Tumor necrosis factor (TNF) synthesis is known to play a major part in numerous inflammatory disorders, and multiple transcriptional and post-transcriptional regulatory mechanisms have therefore evolved to dampen the production of this key proinflammatory cytokine(1,2). The high expression of nicotinamide phosphoribosyltransferase (Nampt), an enzyme involved in the nicotinamide-dependent NAD biosynthetic pathway, in cells of the immune system(3) has led us to examine the potential relationship between NAD metabolism and inflammation. We show here that intracellular NAD concentration promotes TNF synthesis by activated immune cells. Using a positive screen, we have identified Sirt6, a member of the sirtuin family(4), as the NAD-dependent enzyme able to regulate TNF production by acting at a post-transcriptional step. These studies reveal a previously undescribed relationship between metabolism and the inflammatory response and identify Sirt6 and the nicotinamide-dependent NAD biosynthetic pathway as novel candidates for immunointervention in an inflammatory setting.

AB Copy number variants are a recently discovered source of large-scale genomic diversity present in all individuals. We capitalize on these inherent genomic differences, focusing on deletion polymorphisms, to develop informative fluorescence in situ hybridization probes with the ability to unequivocally distinguish between donor and recipient cells in situ. These probes are accurate, specific, highly polymorphic and, notably, can be used to assign genetic identity in situ in a completely gender-independent fashion. We anticipate that these polymorphic deletion probes will be useful in further understanding the dynamics of cellular chimerism after transplantation, including the details of chronic organ rejection, post-transplant lymphoproliferative disorder and graft-versus-host disease, and in optimizing future tissue engineering and pluripotent stem cell therapies.

AB Here we integrated multiphoton laser scanning microscopy and the registration of second harmonic generation images of collagen fibers to overcome difficulties in tracking stromal cell-matrix interactions for several days in live mice. We show that the matrix-modifying hormone relaxin increased tumor-associated fibroblast (TAF) interaction with collagen fibers by stimulating beta(1)-integrin activity, which is necessary for fiber remodeling by matrix metalloproteinases.

AB Many advances in our understanding of the molecules that regulate the development, differentiation and function of T cells have been made over the past few years. One important regulator of T-cell differentiation is the transcription factor GATA-binding protein 3 (GATA3). Although the main function of GATA3 is to act as a master transcription factor for the differentiation of T helper 2 (T(H)2) cells, new research has helped to uncover crucial functions of GATA3 in T cells that go beyond T(H)2-cell differentiation and that are important at earlier stages of haematopoietic and lymphoid-cell development. This Review focuses on the functions of GATA3 from early thymocyte development to effector T-cell differentiation. In addition, we discuss the interactions between GATA3 and other transcription factors and signalling pathways, and highlight the functional significance of the GATA3 protein structure.

AB Studies of osteopontin (OPN)-dependent regulation of immune responses have focused on the cytokine activities of the secreted form of this protein. Recent evidence has revealed that an intracellular form of OPN expressed by dendritic cells regulates the expression of pro-inflammatory cytokines and the differentiation of T helper (T(H))-cell lineages. In this Opinion article, we discuss the properties of both OPN isoforms and their respective contributions to the immune response. We propose that cell-type-specific expression of secreted and intracellular OPN regulates the development of distinct effector T(H) cells, including that of T(H)1 and T(H)17 cells.

AB Antiangiogenic drugs have emerged as effective treatment options for patients with recurrent malignant gliomas (MGs). Though this class of drugs is generally well tolerated, rare life-threatening complications, including thromboembolism, hemorrhage, and gastrointestinal (GI) perforation, are reported. We describe six cases of GI perforation among 244 glioma patients (2.5%) during treatment with antiangiogenic agents in combination with chemotherapy and corticosteroids. Two patients succumbed to this complication, and the others recovered. Because GI perforation is a life-threatening yet treatable complication, neurooncologists must have a low threshold to consider it in patients on antiangiogenic drug therapy who present with abdominal pain and other GI complaints.

AB We previously showed that hypothermia attenuates inflammation in focal cerebral ischemia (FCI) by suppressing activating kinases of nuclear factor-kappa B (NF kappa B). Here we characterize the inflammatory response in global cerebral ischemia (GCI), and the influence of mild hypothermia. Rodents were subjected to GCI by bilateral carotid artery occlusion. The inflammatory response was accompanied by microglial activation, but not neutrophil infiltration, or blood brain barrier disruption. Mild hypothermia reduced CA1 damage, decreased microglial activation and decreased nuclear NF kappa B translocation and activation. Similar anti-inflammatory effects of hypothermia were observed in a model of pure brain inflammation that does not cause brain cell death. Primary microglial cultures subjected to oxygen glucose deprivation (OGD) or stimulated with LPS under hypothermic conditions also experienced less activation and less NF kappa B translocation. However, NF kappa B regulatory proteins were not affected by hypothermia. The inflammatory response following GCI and hypothermia's anti-inflammatory mechanism is different from that observed in FCI.

AB Intracerebral hemorrhage (ICH) is the most feared complication of oral anticoagulant therapy (OAT). While anticoagulated patients have increased severity of bleeding following ICH, they may also be at increased risk for thromboembolic events (TEs) given that they had been prescribed OAT prior to their ICH. We hypothesized that TEs are relatively common following ICH, and that anticoagulated patients are at higher risk for these complications.
Consecutive patients with primary ICH presenting to a tertiary care hospital from 1994 to 2006 were prospectively characterized and followed. Hospital records were retrospectively reviewed for clinically relevant in-hospital TEs and patients were prospectively followed for 90 day mortality.
For 988 patients of whom 218 (22%) were on OAT at presentation, median hospital length of stay was 7 (IQR 4-13) days and 90-day mortality was 36%. TEs were diagnosed in 71 patients (7.2%) including pulmonary embolism (1.8%), deep venous thrombosis (1.1%), myocardial ischemia (1.6%), and cerebrovascular ischemia (3.0%). Mean time to event was 8.4 +/- A 7.0 days. Rates of TE were 5% among those with OAT-related ICH and 8% among those with non-OAT ICH (P = 0.2). After multivariable Cox regression, the only independent risk factor for developing a TE was external ventricular drain placement (HR 2.1, 95% CI 1.1-4.1, P = 0.03). TEs had no effect on 90-day mortality (HR 0.7, 95% CI 0.5-1.1, P = 0.1).
The incidence of TEs in an unselected ICH population was 7.2%. Patients with OAT-related ICH were not at increased risk of TEs.

AB Cerebral vasoconstriction is associated with increased cytosolic Ca(2+) concentration in vascular smooth muscle, presumably due to Ca(2+) influx and Ca(2+) release from intracellular stores. We tested the hypothesis that dantrolene (a blocker of Ca(2+)-induced Ca(2+) release from the ryanodine receptor channel on the sarco-endoplasmic reticulum) would potentiate the action of nimodipine (a voltage-dependent L-type Ca(2+) channel blocker, considered standard therapy for SAH) in inhibiting the vasoconstriction of isolated cerebral arteries.
Sprague-Dawley rat basilar and femoral arteries were analyzed for ryanodine receptor expression by immunofluorescence and PCR. Vasoconstriction of basilar artery ex vivo was measured in a wire myograph while exposed to serotonin (5-HT) or endothelin-1 (ET-1) in the presence or absence of dantrolene (10-100 mu M) and/or nimodipine (30 nM). Femoral artery was examined for comparison.
Basilar and femoral arteries express only the ryanodine receptor 3 (RyR3) isoform. In both basilar and femoral arteries, dantrolene significantly inhibited the constriction to 5-HT, whereas it poorly affected the constriction to ET-1. The inhibitory effect of dantrolene on 5-HT was substantially increased by nimodipine, inducing a 10-fold increase in the 50% effective concentration of 5-HT and a 46% reduction in maximum basilar constriction. In femoral artery, dantrolene modestly affected constriction to phenylephrine and there was no interaction with nimodipine.
Dantrolene has synergistic effects with nimodipine against 5-HT-induced vasoconstriction in isolated cerebral arteries. Dantrolene-nimodipine interaction will require testing in a pathophysiological model but might provide treatment for reducing SAH-related vasospasm or other 5-HT-related vasospastic syndromes, such as Call-Fleming syndrome.

AB Calcium plays a central role in neuronal function and injury. Dantrolene, an inhibitor of the ryanodine receptor, inhibits intracellular calcium release from the sarco-endoplasmic reticulum. We review the available data of dantrolene as a potential neuroprotective agent and briefly summarize its other pharmacologic effects that may have potential applications for patients in the neurointensive care unit (NICU). Areas with the need for continued research are identified.

AB Cerebral vasoconstriction syndromes such as vasospasm after subarachnoid hemorrhage (SAH) and trauma, or Call-Fleming syndrome are difficult to treat, and can lead to substantial disability and death. Dantrolene, a ryanodine receptor antagonist, inhibits intracellular calcium release from the sarco-endoplasmic reticulum. We examined the effect of dantrolene on middle cerebral artery (MCA) blood flow velocities as measured by transcranial Doppler (TCD).
Three consecutive patients with elevated MCA TCD velocities receiving dantrolene (2.5 mg/kg i.v. q6h) were retrospectively reviewed. Average MCA peak systolic, mean flow velocities, and the pulsatility index (PI) before and after the dantrolene infusion were compared within patients. Systemic physiological parameters (blood pressure, heart rate, central venous pressure, intracranial pressure, body temperature, and cooling water temperature) were retrospectively collected 6 h before and after the dantrolene infusion.
MCA peak systolic velocities (mean +/- A SE) for the three patients were 297 +/- A 3, 248 +/- A 8, and 268 +/- A 19 cm/s before dantrolene and 159 +/- A 9, 169 +/- A 8, and 216 +/- A 12 cm/s after dantrolene. Average mean flow velocities showed the same trend. Interestingly, the PI increased slightly from 0.6, 0.52, and 0.67 before dantrolene, to 1.17, 0.71, and 0.77 after dantrolene. Systemic physiological parameters remained stable in all three patients.
Dantrolene attenuated cerebral vasoconstriction as measured by TCD without altering systemic physiological parameters. This suggests that intracellular calcium release from ryanodine channels in smooth muscle might play a role in vasospasm. A prospective study is underway to test this hypothesis.

AB The genetics of Alzheimer's disease (AD) is heterogeneous and remains only ill-defined. We have recently created a freely available and continuously updated online database (AlzGene; http://www.alzgene.org) for which we collect all published genetic association studies in AD and perform systematic meta-analyses on all polymorphisms with sufficient genotype data. In this study, we tested 27 genes (ACE, BDNF, CH25H, CHRNB2, CST3, CTSD, DAPK1, GALP, hCG2039140, IL1B, LMNA, LOC439999, LOC651924, MAPT, MTHFR, MYH13, PCK1, PGBD1, PRNP, PSEN1, SORCS1, SORL1, TF, TFAM, TNK1, GWA_14q32.13, and GWA_7p15.2), all showing significant association with AD risk in the AlzGene meta-analyses, in a large collection of family-based samples comprised of 4,180 subjects from over 1,300 pedigrees. Overall, we observe significant association with risk for AD and polymorphisms in ACE, CHRNB2, TF, and an as yet uncharacterized locus on chromosome 7p15.2 [rs1859849]. For all four loci, the association was observed with the same alleles as in the AlzGene meta-analyses. The convergence of case-control and family-based findings suggests that these loci currently represent the most promising AD gene candidates. Further fine-mapping and functional analyses are warranted to elucidate the potential biochemical mechanisms and epidemiological relevance of these genes.

AB We propose a novel l(1)l(2)-norm inverse solver for estimating the sources of EEG/MEG signals. Based on the standard l(1)-norm inverse solvers, this sparse distributed inverse solver integrates the l(1)-norm spatial model with a temporal model of the source signals in order to avoid unstable activation patterns and "spiky" reconstructed signals often produced by the currently used sparse solvers. The joint spatio-temporal model leads to a cost function with an l(1)l(2)-norm regularizer whose minimization can be reduced to a convex second-order cone programming (SOCP) problem and efficiently solved using the interior-point method. The efficient computation of the SOCP problem allows us to implement permutation tests for estimating statistical significance of the inverse solution. Validation with simulated and human MEG data shows that the proposed solver yields source time course estimates qualitatively similar to those obtained through dipole fitting, but without the need to specify the number of dipole sources in advance. Furthermore, the l(1)l(2)-norm solver achieves fewer false positives and a better representation of the source locations than the conventional l(2) minimum-norm estimates. (C) 2008 Elsevier Inc.

AB This study examined age-related changes in swallowing from an integrated biomechanical and functional imaging perspective in order to more comprehensively characterize changes in swallowing associated with age. We examined swallowing-related fMRI brain activity and videoflouroscopic biomechanics of three bolus types (saliva, water and barium) in 12 young and 11 older adults. We found that age-related neurophysiological changes in swallowing are evident. The group of older adults recruited more cortical regions than young adults, including the pericentral gyri and inferior frontal gyrus pars opercularis and pars triangularis (primarily right-sided). Saliva swallows elicited significantly higher BOLD responses in regions important for swallowing compared to water and barium. In separate videofluoroscopy sessions, we obtained durational measures of supine swallowing. The older cohort had significantly longer delays before the onset of the pharyngeal swallow response and increased residue of ingested material in the pharynx. These findings suggest that older adults without neurological insult elicit more cortical involvement to complete the same swallowing tasks as younger adults. (C) 2008 Elsevier Inc.

AB Over the last 20 years neuroscientists have learned a great deal about the ventral and dorsal object processing pathways in the adult brain, yet little is known about the functional development of these pathways. The present research assessed the extent to which different patterns of neural activation, as measured by changes in blood volume and oxygenation, are observed in infant visual and temporal cortex in response to events that involve processing of featural differences or spatiotemporal discontinuities. Infants aged 6.5 months were tested. Increased neural activation was observed in visual cortex in response to a featural-difference and a spatiotemporal-discontinuity event. In addition, increased neural activation was observed in temporal cortex in response to the featural-difference but not the spatiotemporal-discontinuity event.

AB Most preclinical studies examining the mechanism(s) of action of antidepressants are carried out using male animals. Blockade of serotonin transporter (SERT) function by selective serotonin reuptake inhibitors (SSRIs) is the initial event that triggers a not completely understood process that results in clinical improvement in depression. To investigate whether there are differences in the ability of SSRIs to inhibit the SERT between male and female rats at different phases of the estrous cycle, clearance of locally applied serotonin (5-HT) was measured by in vivo chronoamperometry. Local application of the SSRI, fluvoxamine, directly into the CA3 area of hippocampus increased significantly 5-HT clearance time parameters in male rats and female rats in estrus or diestrus, but not in proestrus. The contribution of ovarian steroids to this result was investigated in ovariectomized (OVX) rats treated with estradiol benzoate (EB) and/or progesterone (P). In OVX-control rats, fluvoxamine increased clearance time parameters, whereas EB and/or P treatment blocked this effect, consistent with what was seen in female rats in proestrus. This effect was gender-specific, since treatment of castrated rats with EB/P had no effect on the ability of fluvoxamine to slow 5-HT clearance. The time course of hormonal effects showed that 1-60 min after local application of 17-beta-estradiol (E-2) into the CA3 region of OVX rats, fluvoxamine had no effect on clearance time of 5-HT. E-2-BSA mimicked E-2's effects at 10 min but not at 60 min. Pretreatment with estrogen receptor antagonists blocked the effects of E-2. The finding that acutely both estradiol and progesterone can inhibit the ability of an SSRI to slow the clearance of 5-HT, may have important implications for the use of SSRIs in women.

AB We previously demonstrated differential activation of the mesocorticolimbic reward circuitry in response to cigarette cues independent of withdrawal. Despite robust effects, we noted considerable individual variability in brain and subjective responses. As dopamine (DA) is critical for reward and its predictive signals, genetically driven variation in DA transmission may account for the observed differences. Evidence suggests that a variable number of tandem repeats (VNTRs) polymorphism in the DA transporter (DAT) SLC6A3 gene may influence DA transport. Brain and behavioral responses may be enhanced in probands carrying the 9-repeat allele. To test this hypothesis, perfusion fMR images were acquired during cue exposure in 19 smokers genotyped for the 40 bp VNTR polymorphism in the SLC6A3 gene. Contrasts between groups revealed that 9-repeat (9-repeats) had a greater response to smoking (vs nonsmoking) cues than smokers homozygous for the 10-repeat allele (10/10-repeats) bilaterally in the interconnected ventral striatal/pallidal/orbitofrontal cortex regions (VS/VP/OFC). Activity was increased in 9-repeats and decreased in 10/10-repeats in the VS/VP/OFC (p<0.001 for all analyses). Brain activity and craving was strongly correlated in 10/10-repeats in these regions and others (anterior cingulate, parahippocampal gyrus, and insula; r(2) = 0.79-0.86, p<0.001 in all regions). Alternatively, there were no significant correlations between brain and behavior in 9-repeats. There were no differences in cigarette dependence, demographics, or resting baseline neural activity between groups. These results provide evidence that genetic variation in the DAT gene contributes to the neural and behavioral responses elicited by smoking cues.

RESECTION; BIAS REDUCTION; HEMORRHAGE; OUTCOMES
AB OBJECTIVE: Stereotactic radiosurgery makes brain arteriovenous malformations (AVM) more manageable during their microsurgical resection. To better characterize these effects, we compared results of microsurgical resection of radiated (RS(+)) and nonradiated (RS(-)) AVMs to demonstrate that previous radiosurgery facilitates surgery and decreases operative morbidity.
METHODS: From our series of 344 patients who underwent AVM resections at the University of California, San Francisco (1997-2007), 21 RS(+) patients were matched with 21 RS- patients based on pretreatment clinical and AVM characteristics. Matching was blinded to outcomes, which were assessed with the modified Rankin Scale.
RESULTS: Mean AVM volume was reduced by 78% (P < 0.01), and Spetzler-Martin grades were reduced in 52% of RS(+) patients (P < 0.001). Preoperative embolization was used less in RS+ than in RS- patients (P < 0.001). Mean operative time (P < 0.01), blood loss (P < 0.05), and length of hospital stay (P < 0.05) were lower in the RS(+) group. Surgical morbidity was 14% higher in RS- patients, and they demonstrated Significant worsening in modified Rankin Scale scores after surgery, whereas RS+ patients did not (P < 0.01). RS(+) patients deteriorated between AVM diagnosis and surgery owing to hemorrhages during the latency period (P < 0.05).
CONCLUSION: Previous radiosurgery facilitates AVM microsurgery and decreases operative morbidity. Radiosurgery is recommended for unruptured AVMs that are not favorable for microsurgical resection. Microsurgical resection is recommended for radiated AVMs that are not completely obliterated after the 3-year latency period but are altered favorably for surgery, even in asymptomatic patients. Prompt resection of persistent AVMs should be considered to avoid the risk of postlatency hemorrhage and to optimize patient outcomes.

AB Among cigarette smokers, lower levels of consumption, defined as smoking fewer cigarettes per day (CPD) or not smoking daily, are becoming more common. The relationship between cigarette consumption and smoking frequency (daily or nondaily) is not well characterized, and the natural history of light smoking (defined here as smoking <= 10 CPD) is poorly understood.
We assessed changes in CPD and smoking frequency over time among light smokers (<= 10 CPD) and very light smokers (<= 5 CPD), using a population-based longitudinal survey of 3,083 adult smokers in Massachusetts who were interviewed three times over a 4-year follow-up period (in 2000-2001, 2002-2003, and 2005-2006). We used logistic regression to identify factors associated with light smokers' progression to heavier smoking or smoking reduction/quitting.
Seventy percent of very light smokers were nondaily smokers. Very light nondaily smokers differed from very light daily smokers by younger age, higher socioeconomic status, a social smoking pattern, later smoking initiation, less evidence of nicotine addiction, and more recent and planned cessation efforts. Very light nondaily smokers and smokers consuming 6-10 CPD were more likely to remain in the same smoking category and were less likely to increase consumption than were very light daily smokers. Factors independently associated with increasing consumption among very light smokers were smoking daily, nicotine dependence, White ethnicity, social smoking, and having more friends who smoked; among smokers consuming 6-10 CPD, male gender and lack of quitting self-efficacy were associated with increasing consumption.
Our findings indicate that most light smoking is not a gateway to heavier smoking.

AB Zinc-finger proteins (ZFPs) have long been recognized for their potential to manipulate genetic information because they can be engineered to bind novel DNA targets. Individual zinc-finger domains (ZFDs) bind specific DNA triplet sequences; their apparent modularity has led some groups to propose methods that allow virtually any desired DNA motif to be targeted in vitro. In practice, however, ZFPs engineered using this modular assembly approach do not always function well in vivo. Here we report a modular assembly scoring strategy that both identifies combinations of modules least likely to function efficiently in vivo and provides accurate estimates of their relative binding affinities in vitro. Predicted binding affinities for 53 three-finger ZFPs, computed based on energy contributions of the constituent modules, were highly correlated (r 0.80) with activity levels measured in bacterial two-hybrid assays. Moreover, K(d) values for seven modularly assembled ZFPs and their intended targets, measured using fluorescence anisotropy, were also highly correlated with predictions (r 0.91). We propose that success rates for ZFP modular assembly can be significantly improved by exploiting the score-based strategy described here.

AB Objectives: The study investigated the utility of unmetabolised naphthalene (Nap) and phenanthrene (Phe) in urine as surrogates for exposures to mixtures of polycyclic aromatic hydrocarbons (PAHs).
Methods: The report included workers exposed to diesel exhausts (low PAH exposure level, n=39) as well as those exposed to emissions from asphalt (medium PAH exposure level, n=26) and coke ovens (high PAH exposure level, n=28). Levels of Nap and Phe were measured in urine from each subject using head space-solid phase microextraction and gas chromatography-mass spectrometry. Published levels of airborne Nap, Phe and other PAHs in the coke-producing and aluminium industries were also investigated.
Results: In post-shift urine, the highest estimated geometric mean concentrations of Nap and Phe were observed in coke-oven workers (Nap: 2490 ng/l; Phe: 975 ng/l), followed by asphalt workers (Nap: 71.5 ng/l; Phe: 54.3 ng/l), and by diesel-exposed workers (Nap: 17.7 ng/l; Phe: 3.60 ng/l). After subtracting logged background levels of Nap and Phe from the logged post-shift levels of these PAHs in urine, the resulting values (referred to as ln(adjNap) and ln(adjPhe), respectively) were significantly correlated in each group of workers (0.71 <= Pearson r <= 0.89), suggesting a common exposure source in each case. Surprisingly, multiple linear regression analysis of ln(adjNap) on ln(adjPhe) showed no significant effect of the source of exposure (coke ovens, asphalt and diesel exhaust) and further suggested that the ratio of urinary Nap/Phe (in natural scale) decreased with increasing exposure levels. These results were corroborated with published data for airborne Nap and Phe in the coke-producing and aluminium industries. The published air measurements also indicated that Nap and Phe levels were proportional to the levels of all combined PAHs in those industries.
Conclusion: Levels of Nap and Phe in urine reflect airborne exposures to these compounds and are promising surrogates for occupational exposures to PAH mixtures.

AB We have previously shown that the death receptor ligand TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) induces an increase of intracellular C(16)-ceramide in sensitive SW480 but not in resistant SW620 cells. Resistance in SW620 cells was overcome by exogenous ceramide, leading us to propose that defective ceramide signaling contributes to TRAIL resistance. In this study we found that the increase in C16-ceramide in SW480 cells was inhibited by fumonisin B1, an inhibitor of ceramide synthases (CerS). Protein analysis revealed that TRAIL-resistant SW620 cells expressed lower levels of ceramide synthase 6 (CerS6, also known as longevity assurance homologue 6), which prompted us to investigate the effect of CerS6 modulation on TRAIL phenotype. RNAi against CerS6 resulted in a specific and significant decrease of the C(16)-ceramide species, which was sufficient to inhibit TRAIL-induced apoptosis. In cells with decreased levels of CerS6, caspase-3 was activated but failed to translocate into the nucleus. CerS6 localized primarily to the perinuclear region, suggesting this enzyme may be important in regulation of nuclear permeability. Moderate elevation in CerS6 expression was sufficient to reverse TRAIL resistance in SW620 cells. These results suggest that modulation of CerS6 expression may constitute a new therapeutic strategy to alter apoptotic susceptibility.

TI Bony changes in the jaws of rats treated with zoledronic acid and

AB Osteonecrosis of the jaw is associated with aminobisphosphonate use in patients treated with intravenous doses for the prevention of bony metastases. A more complete understanding of the natural history of bisphosphonate-related osteonecrosis of the jaws (BRONJ), factors associated with risk, and its pathobiology has been limited by the availability of human material and the absence of clinical predictabitity. We now describe an animal model, developed in female Sprague-Dawley rats, in which we replicate many of the clinical, radiographic, and histologic features described in humans.
Animals treated with a sequence of zoledronic acid (ZA) and dexamethosone (DX) over a one to three week period developed BRONJ-like changes following extraction of mandibular or maxillary molars. Whereas the extraction sites of control animals underwent predictable heating with rapid epithelialization, animals treated with ZA/DX demonstrated clinical and histological evidence of ulceration overlying areas of necrotic bone. In contrast to images from control animals, radiographs from animals treated with ZA/DX demonstrated poor definition of the alveolar ridge with mixed radiodensity. Modest increases in the extent of the inflammatory infiltrate were seen fourteen days after extraction in ZA-only treated animals compared to control or ZA/DX-treated rats. However, by post-extraction day 28, no differences were observed. Tissue vascularity was most pronounced in ZA-only treated animals compared to ZA/DX or control specimens. Apoptosis of epithelial cells was not observed in any experimental groups, and no evidence of Actinomyces was observed as determined by Periodic Acid Schiff (PAS) staining. The administration of ZA/DX preceding dental extractions in rats therefore results in the development of bony and soft tissue changes that are similar to those noted humans who develop BRONJ, and may provide a useful model for study of its pathogenesis, as well as strategies for its prevention and treatment.

AB OBJECTIVE: To determine if patients with human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) treated with chemoradiation have improved outcomes.
STUDY DESIGN: A retrospective search was used to identify patients with OPSCC treated with concurrent chemoradiation. Pretreatment biopsy specimens were tested for HPV-16 infection and p16 expression.
METHODS: Forty-four patients with OPSCC treated with concurrent chemotherapy and intensity-modulated radiation therapy were identified. Eligibility criteria included a minimum two years of follow-up, or biopsy-proven recurrence. In situ hybridization was applied to archival tumor specimens, with HPV-16-positive status defined as positive staining of tumor cell nuclei. p16 expression was assessed by immunohistochemistry.
RESULTS: Twenty-seven tumors (61%) were positive for HPV-16 and 29 tumors (66%) expressed p16. HPV-16 infection was highly correlated with p 16 expression (P < 10(-7)). Three-year disease-free and overall survival for all patients was 66 percent and 79 percent respectively. Patients with tumors infected with HPV-16 had improved overall (OS) and disease-free survival (DFS) after chemoradiation (OS: hazard ratio [HR] = 0.21, P = 0.01; DFS: HR = 0.30, P = 0.02).
CONCLUSION: Patients with OPSCC tumors that are infected with HPV-16 have improved survival after treatment with concurrent chemoradiation.

AB OBJECTIVES: Prior studies showed that immune inhibitory CD34(+) progenitor cells, whose numbers are increased in head and neck squamous cell carcinoma (HNSCC) patients, can be differentiated into immune stimulatory dendritic cells by culture with 1 alpha,25-dihydroxyvitamin D-3 (1,25[OH](2)D-3'). This was extended to a pilot study to diminish intratumoral levels of CD34(+) progenitor cells by inducing their maturation into dendritic cells with 1,25(OH)(2)D-3.
STUDY DESIGN: Newly diagnosed HNSCC patients were untreated for 3 weeks or received 3 weeks of 1,25(OH)(2)D-3 treatment befoer surgical treatment.
SUBJECTS AND METHODS: HNSCC tissue was collected by biopsy from six patients who had no prior 1,25(OH)(2)D-3 treatment and at the time of surgical treatment from six untreated patients and 11 patients who completed 1,25(OH)(2)D-3 treatment. Tissues were analyzed by immunohistochemistry for levels of CD34(+) cells and dendritic cells.
RESULTS: After 1,25(OH)(2)D-3 treatment, intratumoral levels of CD34(+) cells and levels of immature dendritic cells declined. However, levels of intratumoral mature dendritic cells increased. Clinical effects of 1,25(OH)(2)D-3 treatment are premature to analyze.
CONCLUSIONS: Treatment of HNSCC patients with 1,25(OH)(2)D-3 reduced levels of immune inhibitory CD34(+) cells while increasing maturation of dendritic cells. This supports added studies to determine the effect of 1,25(OH)(2)D-3 on intratumoral immune competence.

AB SU5416 is a novel small molecule tyrosine kinase inhibitor of the VEGF receptors 1 and 2. A phase I dose escalation Study stratified by concurrent use (stratum II) or absence (stratum I) of enzyme-inducing anticonvulsant drugs was undertaken to estimate the maximum-tolerated close (MTD) and to describe the toxicity profile of SU5416 in pediatric patients with refractory brain tumors. Dose escalations were conducted independently for stratum I starting at 110 mg/m(2) while stratum II started at 48 mg/m(2). Thirty-three eligible patients were treated on stratum I (n=23) and stratum II (n=10). Tumor types included 23 glial tumors, 4 neural tumors, 4 ependymomas, and 2 choroid plexus carcinomas. The MTD in stratum I was initially estimated to be 110 mg/m(2). The protocol was amended to determine the MTD after excluding transient AST elevation. Re-estimation of the MTD began at the 145 mg/m(2) close level but clue to development of SU5416 being stopped by the sponsor, the trial was closed before completion. The most Serious drug-related toxicities were grade 3 liver enzyme abnormalities, arthralgia, and hallucinations. The plasma pharmacokinetics of SU5416 was not significantly affected by the concurrent administration of enzyme-inducing anticonvulsant drugs. Mean Value,.; of the total body clearance, apparent volume of distribution, and terminal phase half-life of SUS416 for the 19 patients in stratum I were 26.1 +/- 12.5 l/hr/m(2), 41.9 +/- 21.4 l/m(2), and 1.11 +/- 0.41 hr, respectively.

AB Background. To estimate the response rate and therapy related toxicities of the anti-CD20 monoclonal antibody rituximab when combined with chemotherapy including ifosfamide, carboplatin, and etoposide (ICE) in patients with relapsed and refractory B-cell non-Hodgkin lymphoma and mature B-cell acute lymphoblastic leukemia (B-ALL). Methods. Patients received rituximab and ICE for 1-3 cycles, depending upon response. Rituximab (375 mg/m(2)) was given oil clay 1 and 3 of each cycle (day I only for cycle 3), with ifosfamide (3,000 mg/m(2)) and etoposide (100 mg/m(2)) given on days 3, 4, and 5 and carboplatin (635 mg/m(2)) given oil clay 3 only. Results. Twenty-one patients were enrolled, of whom 20 were eligible and evaluable. Although hematologic toxicities were common, only one patient was removed from study due to prolonged myelosuppression. Toxicities related to infusions of rituximab were frequent hot manageable. Of the six eligible patients With diffuse large B-cell lymphoma, three achieved complete remission (CR), one had stable disease (SD), and two had progressive disease (PD). Of the 14 eligible patients with Burkitt lymphoma and B-ALL, there were four complete responses (CR), five partial responses (PR), one SD, and four with PD. Thus, the CR/PR rate for the entire group was 12/20 (60%). Following completion of protocol therapy six patient. Were able to proceed to consolidation with high-close therapy and stern cell rescue. Conclusions. The combination of rituximab and ICE chemotherapy was associated with all encouraging objective response (OR) rate and in acceptable toxicity profile.

AB Background. We previously showed in a prospective Study that rituximab appears to be effective in some children and adolescents with severe chronic immune thrombocytopenia. Eleven of 36 patients achieved and maintained platelet counts Over 50,000/mm(3) within the first 12 weeks. These patients were followed for the next year. Methods. Platelet Count,; were monitored monthly and all subsequent bleeding manifestations and need for further treatment was noted. Results. Eight of the 11 initial responders maintained a platelet count over 150,000/mm(3) Without further treatment intervention. Three patients had a late relapse. One initial non-responder achieved a remission after 16 weeks, and two additional patients maintained platelet counts around 50,000/mm(3) without the need for further intervention. Conclusions. Rituximab resulted in sustained efficacy with platelet Counts of 50,000/mm(3) or higher in 11 of 36 patients (31%). Pediatr Blood Cancer 2009;52:259-262. (C) 2008 Wiley-Liss, Inc.

AB RSV-infected children demonstrate various radiographic features, some of which are associated with worse clinical outcomes.
To investigate whether specific chest radiological patterns in RSV-infected children with acute respiratory failure (ARF) in the peri-intubation period are associated with prolonged duration of mechanical ventilation.
We included RSV-infected children < 1 year of age admitted with ARF from 1996 through 2002 to the pediatric intensive care unit at Massachusetts General Hospital. Their chest radiographs were evaluated at three time-points: preintubation (day -1) and days 1 and 2 after intubation. Univariate and multiple logistic regressions models were utilized to investigate our objective.
The study included 46 children. Using day 1 chest radiograph findings to predict duration of mechanical ventilation of > 8 days, a backward stepwise regression arrived at a model that included age and right and left lung atelectasis. Using day 2 chest radiograph results, the best model included age and left lung atelectasis. A model combining the two days' findings yielded an area under the ROC curve of 0.92 with a satisfactory fit (P = 0.95).
Chest radiological patterns around the time of intubation can identify children with RSV-associated ARF who would require prolonged mechanical ventilation.

AB Modulation of the intestinal immune response early in life by administration of probiotic bacteria may be an effective strategy for preventing or attenuating infectious diarrhea. We preinoculated the mice early in life with the probiotic bacteria Lactobacillus acidophilus NCFM (La) at age 2 wk. Dendritic cells (DCs) were collected and purified front mesenteric lymph nodes (MLN) and spleens of the BalbC/ByJ mice. DC isolation and adoptive transfer was used to examine the function of probiotics. We demonstrated that when mice were adoptively transferred with La-primed DCs (t-LaDC) instead of oral consumption with La, there was a similar effect off fecal bacteria counts. IgA levels. and colonic histopathology, as well as cytokine levels in MLN when there was intestinal bacterial infection. The above findings suggest that DCs play a key role in probiotics attenuating Citrobacter rodentitum (Cr) colitis. Moreover, the location of La-primed DC hints that there is interaction of DCs and T cells in the digestive system of the host. Up-regulated expression Of a surface marker on DCs indicated that inoculation with probiotics will stimulate the function of DCs. thereby further increasing immune response triggered by DC.

AB The Arabidopsis (Arabidopsis thaliana) hexokinase 1 (AtHXK1) is recognized as an important glucose (Glc) sensor. However, the function of hexokinases as Glc sensors has not been clearly demonstrated in other plant species, including rice (Oryza sativa). To investigate the functions of rice hexokinase isoforms, we characterized OsHXK5 and OsHXK6, which are evolutionarily related to AtHXK1. Transient expression analyses using GFP fusion constructs revealed that OsHXK5 and OsHXK6 are associated with mitochondria. Interestingly, the OsHXK5 Delta mTP-GFP and OsHXK6 Delta mTP-GFP fusion proteins, which lack N-terminal mitochondrial targeting peptides, were present mainly in the nucleus with a small amount of the proteins seen in the cytosol. In addition, the OsHXK5NLS-GFP and OsHXK6NLS-GFP fusion proteins harboring nuclear localization signals were targeted predominantly in the nucleus, suggesting that these OsHXKs retain a dual-targeting ability to mitochondria and nuclei. In transient expression assays using promoter::luciferase fusion constructs, these two OsHXKs and their catalytically inactive alleles dramatically enhanced the Glc-dependent repression of the maize (Zea mays) Rubisco small subunit (RbcS) and rice alpha-amylase genes in mesophyll protoplasts of maize and rice. Notably, the expression of OsHXK5, OsHXK6, or their mutant alleles complemented the Arabidopsis glucose insensitive2-1 mutant, thereby resulting in wild-type characteristics in seedling development, Glc-dependent gene expression, and plant growth. Furthermore, transgenic rice plants overexpressing OsHXK5 or OsHXK6 exhibited hypersensitive plant growth retardation and enhanced repression of the photosynthetic gene RbcS in response to Glc treatment. These results provide evidence that rice OsHXK5 and OsHXK6 can function as Glc sensors.

AB Background: Ischemic postconditioning, the process of exposing tissues to brief cycles of ischemia-reperfusion after critical ischemia, can mitigate local ischemia-reperfusion injury. Remote protection of skeletal muscle has never been demonstrated in postconditioning models of ischemia-reperfusion injury.
Methods: Mice were subjected to 2 hours of ipsilateral hind limb ischemia followed by reperfusion. Contralateral limb ischemia was subsequently induced for 2 hours after either 0 (n = 6), 20 (n = 6), or 120 (n = 5) minutes of ipsilateral limb reperfusion. These groups were compared with animals subjected to bilateral simultaneous injury (n = 8) and sham animals that did not undergo ischemia (n = 6). The gastrocnemius muscles were harvested for histologic evaluation, and injury was recorded as the percentage of injured fibers.
Results: The first limbs undergoing injury in the 20-minute interval group had a 59 percent injury reduction compared with contralateral limbs (16.0 +/- 2.4 percent versus 39.5 +/- 6.5 percent) after 24 hours of reperfusion and 62 percent reduction after 48 hours (24.4 +/- 3.0 percent versus 63.6 +/- 5.5 percent). In animals with no interval or a 120-minute interval between the onset of limb ischemia, there was no significant difference in injury between hind limbs. The injury in these groups was similar to that in hind limbs subjected to simultaneous bilateral ischemia.
Conclusions: A 20-minute reperfusion interval between hind limb ischemia significantly protects against injury in the initially ischemic limb, while similar injury is observed with simultaneous ischemia or an interval of 120 minutes. This study demonstrates remote postconditioning of skeletal muscle and may lead to the development of post hoc therapies. (Plast. Reconstr. Surg. 123 (Suppl.): 8S, 2009.)

AB Background: Transplantation of embryonic stem cell-derived motor neurons may support the biological integrity of denervated muscle by forming new neuromuscular junctions and up-regulating specific growth factors. The authors examined the functional properties of embryonic stem cell-derived motor neurons in vitro and the effect of these cells transplanted in vivo.
Methods: Murine GFP/HB9 embryonic stem cells were differentiated into motor neurons. Co-cultures of motor neurons and myotubes were prepared to confirm the formation of neuromuscular junctions with synaptic markers. Athymic mice (n = 59) were assigned randomly to one of three experimental groups. A tibial nerve transection was performed without nerve repair, and motor neurons were transplanted into the gastrocnemius muscles immediately after transection (n = 24) or 3 weeks after denervation (n = 24). Quantitative and histologic assessments of gastrocnemius muscle were performed at days 7 and 21 after cell transplantation. Additional experimental groups (n = 11), where the tibial nerve underwent repair after transplantation, were formed. The effect of the transplants on motor recovery following nerve repair was investigated.
Results: Co-culture experiments showed the formation of neuromuscular junctions. In the experiment with nerve transection without nerve repair, the muscles transplanted with motor neurons were less atrophied than control phosphate-buffered saline-injected muscles at days 7 and 21. Those muscles receiving cells transplanted 3 weeks after denervation were not preserved. The motor recovery after nerve repair with cell transplantation was significantly enhanced compared with the control group.
Conclusions: Transplantation of motor neurons prevented denervation atrophy but was not capable of rescuing already atrophied muscle. After nerve repair, motor neuron transplantation improved functional recovery. (Plast. Reconstr. Surg. 123 (Suppl.): 139S, 2009.)

AB Many components of Wnt/beta-catenin signaling pathway also play critical roles in mammary tumor development, yet the role of the tumor suppressor gene APC (adenomatous polyposis coli) in breast oncongenesis is unclear. To better understand the role of Apc in mammary tumorigenesis, we introduced conditional Apc mutations specifically into two different mammary epithelial populations using K14-cre and WAP-cre transgenic mice that express Cre-recombinase in mammary progenitor cells and lactating luminal cells, respectively. Only the K14-cre-mediated Apc heterozygosity developed mammary adenocarcinomas demonstrating histological heterogeneity, suggesting the multilineage progenitor cell origin of these tumors. These tumors harbored truncation mutation in a defined region in the remaining wild-type allele of Apc that would retain some down-regulating activity of beta-catenin signaling. Activating mutations at codons 12 and 61 of either H-Ras or K-Ras were also found in a subset of these tumors. Expression profiles of acinar-type mammary tumors from K14-cre; Apc(CKO/+) mice showed luminal epithelial gene expression pattern, and clustering analysis demonstrated more correlation to MMTV-neu model than to MMTV-Wnt1. In contrast, neither WAP-cre-induced Apc heterozygous nor homozygous mutations resulted in predisposition to mammary tumorigenesis, although WAP-cre-mediated Apc deficiency resulted in severe squamous metaplasia of mammary glands. Collectively, our results suggest that not only the epithelial origin but also a certain Apc mutations are selected to achieve a specific level of beta-catenin signaling optimal for mammary tumor development and explain partially the colon-but not mammary-specific tumor development in patients that carry germline mutations in APC.

AB It has been argued that the limited genetic diversity and reduced allelic heterogeneity observed in isolated founder populations facilitates discovery of loci contributing to both Mendelian and complex disease. A strong founder effect, severe isolation, and substantial inbreeding have dramatically reduced genetic diversity in natives from the island of Kosrae, Federated States of Micronesia, who exhibit a high prevalence of obesity and other metabolic disorders. We hypothesized that genetic drift and possibly natural selection on Kosrae might have increased the frequency of previously rare genetic variants with relatively large effects, making these alleles readily detectable in genome-wide association analysis. However, mapping in large, inbred cohorts introduces analytic challenges, as extensive relatedness between subjects violates the assumptions of independence upon which traditional association test statistics are based. We performed genome-wide association analysis for 15 quantitative traits in 2,906 members of the Kosrae population, using novel approaches to manage the extreme relatedness in the sample. As positive controls, we observe association to known loci for plasma cholesterol, triglycerides, and C-reactive protein and to a compelling candidate loci for thyroid stimulating hormone and fasting plasma glucose. We show that our study is well powered to detect common alleles explaining >= 5% phenotypic variance. However, no such large effects were observed with genome-wide significance, arguing that even in such a severely inbred population, common alleles typically have modest effects. Finally, we show that a majority of common variants discovered in Caucasians have indistinguishable effect sizes on Kosrae, despite the major differences in population genetics and environment.

AB Making sense of rapidly evolving evidence on genetic associations is crucial to making genuine advances in human genomics and the eventual integration of this information in the practice of medicine and public health. Assessment of the strengths and weaknesses of this evidence, and hence the ability to synthesize it, has been limited by inadequate reporting of results. The STrengthening the REporting of Genetic Association studies (STREGA) initiative builds on the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement and provides additions to 12 of the 22 items on the STROBE checklist. The additions concern population stratification, genotyping errors, modelling haplotype variation, Hardy-Weinberg equilibrium, replication, selection of participants, rationale for choice of genes and variants, treatment effects in studying quantitative traits, statistical methods, relatedness, reporting of descriptive and outcome data, and the volume of data issues that are important to consider in genetic association studies. The STREGA recommendations do not prescribe or dictate how a genetic association study should be designed but seek to enhance the transparency of its reporting, regardless of choices made during design, conduct, or analysis.

AB Viral persistence is associated with hierarchical antiviral CD8 T cell exhaustion with increased programmed death-1 (PD-1) expression. In HCV persistence, HCV-specific CD8 T cells from the liver (the site of viral replication) display increased PD-1 expression and a profound functional impairment that is not reversed by PD-1 blockade alone. Here, we report that the inhibitory receptor cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) is preferentially upregulated in PD-1(+) T cells from the liver but not blood of chronically HCV-infected patients. PD-1/CTLA-4 co-expression in intrahepatic T cells was associated with a profound HCV-specific effector dysfunction that was synergistically reversed by combined PD-1/CTLA-4 blockade in vitro, but not by blocking PD-1 or CTLA-4 alone. A similar effect was observed in circulating HCV-specific CD8 T cells with increased PD-1/CTLA-4 co-expression during acute hepatitis C. The functional response to combined blockade was directly associated with CTLA-4 expression, lost with CD28-depletion and CD4-independent (including CD4(+)FoxP3(+) Tregs). We conclude that PD-1 and CTLA-4 pathways both contribute to virus-specific T cell exhaustion at the site of viral replication by a redundant mechanism that requires combined PD-1/CTLA-4 blockade to reverse. These findings provide new insights into the mechanisms of virus-specific T cell dysfunction, and suggest that the synergistic effect by combined inhibitory receptor blockade might have a therapeutic application against chronic viral infection in vivo, provided that it does not induce autoimmunity.

AB A growing body of literature suggests that computerized cognitive-behavioral therapies (CCBT) are effective in community settings in terms of symptom reduction, favorable client satisfaction, attrition comparable to standard cognitive-behavioral therapy, reduced clinician time, high cost-effectiveness, and ease of integration into community clinics. Clinicians report lack of knowledge about computerized programs as the main reason that they have not used CCBT in their practice. To mitigate this disconnect between empirical evidence and dissemination, this article first reviews empirical studies focusing on the efficacy of CCBT for specific psychological disorders, followed by a review of research on the effectiveness of CCBT in community settings. Next, issues related to dissemination and barriers to CCBT adoption by clinicians are discussed. Finally, the implications of CCBT for research and practice and the possible role of CCBT in a stepped care model of treatment is discussed in terms of cost-effectiveness, standards of care, and implications for public policy.

AB The liver plays a major role in the early hypometabolic and later hypermetabolic phases after severe burn injury. Proteomic analysis was used to identify altered proteins in liver during these two phases. Sprague-Dawley rats were subjected to a full-thickness dorsal burn injury covering 40% of the total body surface area. Controls consisted of sham-treated animals. Liver tissues were collected on postburn days 1 and 7. The proteomic data show greater production of positive acute phase proteins on day 1 than on day 7. Many antioxidant enzymes were coordinately downregulated on day 1, including the potent biliverdin reductase. These antioxidants were restored and in some cases upregulated on day 7. This opposite trend in the change of antioxidant proteins corroborated our finding of more pronounced oxidative stress on day 1 than on day 7 as measured via protein carbonyl content. The changes of metabolic enzymes on days 1 and 7 were consistent with hypo- and hyper-metabolic states, respectively. Furthermore, a previously unreported decrease in ornithine aminotransferase on day 7 may be a key contributor to the observed increased urinary urea excretion during the hypermetabolic phase. Overall, the many differences in protein expression observed on postburn days 1 and 7 reflect the dissimilar hepatic metabolic patterns during the acute and flow phases following burn injury.

AB Green tea polyphenols exhibit multiple antitumor activities, and the mechanisms of action are not completely understood. Previously, we reported that green tea extract (GTE)-induced actin remolding is associated with increased cell adhesion and decreased motility in A549 lung cancer cells. To identify the cellular targets responsible for green tea-induced actin remodeling, we performed 2-DE LC-MS/MS of A549 cells before and after GTE exposure. We have identified 14 protein spots that changed in expression (>= 2-fold) after GTE treatment. These proteins are involved in calcium-binding, cytoskeleton and motility, metabolism, detoxification, or gene regulation. In particular we found upregulation of several genes that modulate actin remodeling and cell migration, including lamin A/C. Our data indicated that GTE-induced lamin A/C upregulation appears to be at the transcriptional level and the increased expression results in the decrease in cell motility, as confirmed by siRNA. The result of the study demonstrates that GTE alters the levels of many proteins involved in growth, motility and apoptosis of A549 cells and their identification may explain the multiple antitumor activities of GTE.

AB There is a growing consensus that a hybrid of two common approaches to quality improvement (QI), local participatory QI and expert QI, might be the best method for achieving quality care. Achieving such a hybrid requires that content experts establish an ongoing dialogue with both frontline staff members and managers. In this study we examined frontline staff members' and managers' preferences regarding how to conduct such a dialogue, and we provide practical suggestions for implementation. The two groups shared a number of preferences (e.g., verbal face-to-face exchanges, discussions focused on quality of care). There were also some differences. For example, although managers were interested in discussions of business aspects (e.g., costs), frontline staff members were concerned with workload issues. Finally, although informants acknowledged that engaging in a QI dialogue was time consuming, they also believed it was essential if health care organizations are to improve the quality of care they provide.

SO QUALITY & SAFETY IN HEALTH CARE

DT Article

AB Background: Medication-prescribing discrepancies are used as a quality measure for patients transferred between sites of care. The objective of this study was to quantify the rate of adverse drug events (ADEs) caused by prescribing discrepancies and the discrimination of an index of high-risk transition drug prescribing.
Methods: We examined medical records of patients transferred between seven nursing homes and three hospitals between 1999 and 2005 in New York and Connecticut for transfer- associated prescribing discrepancies. ADEs caused by discrepancies were determined by two clinician raters. We calculated the fraction of medication discrepancies that caused ADEs in each of 22 drug classes by calculating positive predictive values (PPVs). We calculated the discrimination of a count of high-risk drug discrepancies, selected from published lists of high-risk medications and using observed PPVs.
Results: 208 patients were hospitalised 304 times. Overall, 65 of 1350 prescribing discrepancies caused ADEs, for a PPV of 0.048 (95% CI 0.037 to 0.061). PPVs by drug class ranged from 0 to 0.28. Drug classes with the highest PPVs were opioid analgesics, metronidazole, and non-opioid analgesics. Patients with 0, 1-2 and >= 3 high-risk discrepancies had a 13%, 23% and 47% chance of experiencing a discrepancy-related ADE, respectively.
Conclusions: Discrepancies in certain drug classes more often caused ADEs than other types of discrepancies in hospitalised nursing-home patients. Information about ADEs caused by medication discrepancies can be used to enhance measurement of care quality, identify high-risk patients and inform the development of decision-support tools at the time of patient transfer.

AB Objective: The current study investigated individual growth in autonomy development across the adolescent transition, comparing the trajectories of children with and without spina bifida. Method: Individual growth curve modeling procedures were utilized to describe the developmental course of autonomy across four waves of data collection, from ages 9 to 15, and to test whether illness status [spina bifida vs. matched comparison group (N = 68 for both groups at Time 1)] would significantly predict individual variability in autonomy development. Potential moderators [child gender, SES, and Peabody Picture Vocabulary Test (PPVT) score] of the association between illness status and autonomy development were also examined. Results: Children with spina bifida demonstrated distinct developmental trajectories, though the nature of the group differences varied by type of autonomy development (emotional vs. behavioral), context (i.e. school vs. family), and reporter. Significant interactions with PPVT score and child gender were found. Conclusion: Overall, children with spina bifida show considerable developmental resiliency, but may lag behind their peers in specific areas of autonomy. Boys with spina bifida, and children with spina bifida who have lower than average levels of verbal intelligence, appear to be at greater risk for exhibiting delays in autonomy development.

AB Objective: To evaluate the contribution injection anxiety to disease modifying therapy (DMT) adherence among individuals with multiple sclerosis (MS). Injection anxiety has been associated with medication discontinuation early in the course of treatment, but little is known about the relationship between injection anxiety and sustained DMT adherence over time. Method. Eighty-nine outpatients receiving care at a Veterans Administration MS clinic completed a telephone survey at baseline and monthly telephone follow-up for 6 months. Results: Participants were established DMT users (M = 3.43 years, SD = 3.29), with relatively high adherence overall (over 80% achieved 80% adherence or greater). Using logistic regression and controlling for demographics, MS disability, type of DMT, and time on DMT, the authors found that baseline injection anxiety predicted lower levels of adherence at 4 months and 6 months, with a similar trend at 2 months. Conclusion: Sustained adherence to DMT remains a challenge for a subset of individuals with MS well beyond the initial period of acclimation. Injection anxiety is an important and promising target of psychological intervention during all periods of medication use.

AB A non-experimental longitudinal prospective study was conducted to examine the relationships between patient-centered nursing interventions (PCNIs), system characteristics, patient characteristics, and desired health outcomes (DHOs) for 173 hematology-oncology patients. Forty-nine nurse Participants Provided system characteristics data. Confirmatory factor analyses yielded Parsimonious scales to operationalize the variables. In the Path model, one PCNI-individualization-was positively related to three subsequent DHOs: authentic self-representation, optimism, and sense of well-being. Two additional PCNIs-responsiveness and proficiency-were positively related to subsequent trust in nurses. PCNIs did not vary with patient race, ethnicity, age, gender, or educational level. Patient-centeredness of care for cancer patients may be enhanced by quality improvement activities that measure and monitor these PCN Is and resultant outcomes. (c) 2008 Wiley Periodicals, Inc.

AB Most of the large quantity of data on noninvasive ventilation (NIV) in acute respiratory failure is from patients who want all possible treatments and life-support. Few data are available on NIV in patients who have elected specific limits on life support and treatments (eg, patients with do-not-intubate [DNI] orders) and patients who are near the end of life and will receive comfort measures only (CMO). The most critical issue regarding NIV in DNI and CMO patients is informed consent. The patient must be informed of the risks and potential benefits of NIV, and must consent to NIV. We have few data on patients' attitudes about NIV at end of life. Data from cancer patients at end of life suggest that they want to maintain control over care decisions and may want treatment that delays death long enough that they can put their affairs in order. If informed consent and control of care decisions are assured, then NIV can be appropriate in DNI and CMO patients to reverse an acute respiratory failure that is not necessarily life-terminating, or to improve patient comfort, or to delay death.

AB Noninvasive ventilation (NIV) is under-utilized, despite robust evidence supporting its use in appropriately selected patients with acute respiratory failure. Diffusion of NIV into practice requires that clinicians view it as better than invasive ventilation, that it is perceived as compatible with existing approaches to mechanical ventilation, that it is not too difficult to apply, that it is trialable, and that its results are visible. Barriers to NIV use include lack of awareness of the evidence, lack of agreement with the evidence, lack of self-efficacy, unrealistic outcome expectations, and the inertia of previous practice. A flexible, tireless, enthusiastic, and knowledgeable clinical champion is important when initiating an NIV program. Knowledge and training are also important; ideally the training should be one-on-one and hands-on to the extent possible. Adequate personnel and equipment resources are necessary when implementing the program. Guidelines and protocols may be useful as educational resources, to avoid clinical conflict and consolidate authority. When initiating an NIV program it is important to recognize that NIV does not avoid intubation in all cases. Success often improves with experience. The available evidence suggests that NIV is cost-effective. For optimum success the multidisciplinary nature of NIV application must be recognized. The NIV program should be a quality-improvement initiative. Following these principles, a successful program can be initiated in any acute-care setting.

AB Background: Schizophrenia and alcohol dependence are major risk factors for a variety of medical problems, yet there has been little research on the medical status of patients in whom both conditions coexist.
Methods: We assessed the prevalence and severity of medical illness in 80 patients with schizophrenia or schizoaffective disorder and comorbid alcohol use disorders who entered a controlled trial of monitored naltrexone treatment, and analyzed the relationship between medical illness burden and demographic variables, alcohol and other substance use, and psychosis. Participants underwent physical examination, laboratory tests, medical record review and standardized assessments of medical illness burden, alcohol and other substance use, and psychosis. Nested block multiple regression analyses were used to assess the contribution to illness burden made by demographic variables, alcohol and substance use, and psychosis severity.
Results: 83% of participants had at least one chronic medical illness, hypertension being the most common (43%). Medical comorbidity in this cohort was more severe than for schizophrenia patients in the CATIE trial (Chwastiak, L. Rosenheck, R., McEvoy, J.P., Keefe, R.S., Swartz, M.S., Lieberman,J.A., 2006. Interrelationships of Psychiatric Symptom Severity, Medical Comorbidity, and Functioning in Schizophrenia. Psychiatr. Serv., 57(8), 1102-1109.); the prevalence of hypertension, chronic obstructive pulmonary disease, and coronary artery disease, was more than twice greater. Medical illness burden correlated with alcohol use severity, but appeared to be independent of other substance use or psychosis severity.
Conclusions: Patients with co-occurring alcohol use disorder may have significantly more medical illness burden than patients with schizophrenia or schizoaffective disorder alone. Interventions to reduce alcohol use may be necessary to lessen medical morbidity. Published by Elsevier B.V.

AB Existing measures for functional assessment do not adequately address the relationship between cognitive impairment and function. The Schizophrenia Outcomes Functioning Interview (SOFI) was developed to measure community functioning related to cognitive impairment and psychopathology.
Following review of existing measures and discussion with experts, caregivers, and patients, content was generated for four domains: 1) living situation; 2) IADLs; 3) productive activities; and 4) social functioning. The final SOFI was constructed with items informing domain scores, and an interviewer-completed global rating for each domain.
Psychometric characteristics of the SOFI were evaluated in a sample of 104 community residing patients with schizophrenia and their informants. Test-retest reliability was evaluated in a subsample of patient-informant dyads using ICC; all values were >0.70 for both patient-interviews (SOFI-P) and informant-interviews (SOFI-I). Inter-rater reliability ICCs ranged from 0.50 to 0.79 on a different sub-sample. The SOFI demonstrated adequate construct validity based on correlations with the PSP (range 0.58 to 0.76; p < 0.0001) and the QLS (p < 0.001). Some correlations between SOFI and PETiT scores were low to moderate (p < 0.05). Discriminant validity was supported based on SOFI score comparisons for patient groups based on PANSS and BACS scores (p < 0.05); SOFI scores differed between borderline and moderately ill patients as measured by the CGI-S (p < 0.05).
The SOFI expands on existing measures and more comprehensively captures functioning of patients in the real world than other performance-based (proxy) measures. The SOFI has good evidence supporting reliability and construct validity, and may be a useful measure of functional outcomes in schizophrenia. (C) 2008 Elsevier B.V. All rights reserved.

AB Since Kraepelin called dementia praecox what we nowadays call schizophrenia, cognitive dysfunction has been regarded as central to its psychopathological profile. Disturbed experience and integration of emotions are, both intuitively and experimentally, likely to be intermediates between basic, non-social cognitive disturbances and functional outcome in schizophrenia. While a number of studies have consistently proven that, as part of social cognition, recognition of emotional faces and voices is disturbed in schizophrenics, studies on multisensory integration of facial and vocal affect are rare.
We investigated audiovisual integration of emotional faces and voices in three groups: schizophrenic patients, non-schizophrenic psychosis patients and mentally healthy controls, all diagnosed by means of the Schedules of Clinical Assessment in Neuropsychiatry (SCAN 2.1). We found diminished crossmodal influence of emotional faces on emotional voice categorization in schizophrenics, but not in non-schizophrenia psychosis patients. Results are discussed in the perspective of recent theories on multisensory integration. (C) 2008 Elsevier B.V. All rights reserved.

AB The melanocyte stem cells of the hair follicle provide an attractive system for the study of stem cells. The stem cells exist in an anatomically defined niche clearly separated from their differentiated progeny, differentiated progeny can be selected against by treatment with an inhibitor of Stem Cell Factor signaling, perturbations which affect survival and differentiation have clearly visible pigmentation phenotypes, and genetic mutations can impair or completely abolish this lineage without lethality. In mice several coat color mutants have been shown to have impaired specification or survival of melanocyte stem cells. Furthermore understanding of the normal regulation and behaviors of melanocytes and melanocyte stem cells will allow development of better strategies for cancer treatment. This article will review the discovery and behaviors of melanoctye stem cells as well as some aspects of melanocyte biology. Published by Elsevier Ltd.

AB Antibody-secreting cells (ASCs) lodging in the mucosa of the small intestine are derived from activated B cells that are thought to arise in gut-associated lymphoid tissues (GALT). Upon leaving the GALT, B cells return to the blood where they must express the gut-homing receptors alpha 4 beta 7 and CCR9 in order to emigrate into the small bowel. Recent evidence indicates that gut-associated dendritic cells (DCs) in GALT induce gut-homing receptors on B cells via a mechanism that depends on the vitamin A metabolite retinoic acid (RA). In addition, although ASC associated with other mucosal tissues secrete IgA in an RA-independent fashion, the presence of high levels of RA in intestine and GALT can promote B cell class switching to IgA and thus, boost the production of IgA in the intestinal mucosa. Here, we discuss the role of RA in the imprinting of gut-homing ASC and the evidence linking RA with the generation of intestinal IgA-ASCs. (C) 2008 Elsevier Ltd. All rights reserved.

AB Healthcare-associated pneumonia (HCAP) is a unique entity that differs from community-acquired pneumonia in both bacteriology and outcomes and has similarities to hospital-acquired pneumonia and ventilator-associated pneumonia. HCAP patients are at higher risk of potential multidrug-resistant pathogens, including resistant grain-negative organisms, especially Pseudomonas aeruginosa and Acinetobacter spp., but also extended-spectrum beta-lactamases (ESBLs). This manuscript reviews the epidemiology, etiology, and clinical outcomes of hospitalized HCAP patients due to gram-negative bacteria. We win focus our attention on the potential multidrug-resistant pathogens to suggest a new treatment approach for these patients.

AB Background: To assess the covariates of alcohol abuse and the association between alcohol abuse, high-risk sexual behaviors and sexually transmitted infections (STIs).
Methods: Two thousand and nineteen women aged 20 to 44 were randomly selected in a 2-stage sampling from the Moshi urban district of northern Tanzania. Participant's demographic and socio-economic characteristics, alcohol use, sexual behaviors, and STIs were assessed. Blood and urine samples were drawn for testing of human immunodeficiency virus, herpes simplex virus, syphilis, chlamydia, gonorrhea, trichomonas, and mycoplasma genitalium infections.
Results: Adjusted analyses showed that a history of physical (OR 2.05; 95% CI: 1.06-3.98) and sexual violence (OR = 1.63; 95% CI: 1.05-2.51) was associated with alcohol abuse. Moreover, alcohol abuse was associated with number of sexual partners (OR = 1.66; 95% CI: 1.01-2.73). Women who abused alcohol were more likely to report STIs symptoms (OR = 1.61; 95%, CI: 1.08-2.40). Women who had multiple sexual partners were more likely to have an STI (OR = 2.41; 95% CI: 1.46-4.00.) compared to women with I sexual partner. There was no direct association between alcohol abuse and prevalence of STIs (OR = 0.86; 95% CI: 0.55-134). However, alcohol abuse was indirectly associated with STIs through its association with multiple sexual partners.
Conclusions: The findings of alcohol abuse among physically and sexually violated women as well as the association between alcohol abuse and a history of symptoms of STIs and testing positive for STIs have significant public health implications. In sub-Saharan Africa, where women are disproportionately affected by the HIV epidemic screening for alcohol use should he part or comprehensive STIs and HIV prevention programs.

AB In 70 consecutive male patients with obstructive sleep apnea (OSA) diagnosed at the Northport VA Medical Center Sleep Disorders Center, we have characterized the association between obesity, OSA, and pulmonary hypertension (PH).
By including anthropometric, pulmonary function, and sleep study parameters in a multivariate logistic regression model, we found that a BMI of > 40 kg/m(2) and the minimum oxygen saturation in non-rapid eye movement (NREM) sleep predicted the presence of pretibial edema in this sleep apnea population. We then characterized the hemodynamics of those OSA patients that had lower extremity edema. Twenty-nine of the 70 consecutive patients with sleep apnea (41%) had pretibial edema, and right heart catheterization data was obtained for 28 (97%) of these patients.
Ninety-three percent (26/28) of the patients had right heart failure (mean RAP > 5 mm Hg; RAP range = 0-32 mmHg) and PH (PA mean a parts per thousand yenaEuro parts per thousand 20 mm Hg) was present in 86% (24/28.) The OSA patients with lower extremity edema had an increased cardiac output (7.0 + 1.4 l/min) with a normal cardiac index (2.9 + 0.5 l/min/m(2)) in the setting of an elevated pulmonary capillary wedge pressure (PCWP 17 +/- 7 mmHg) and a normal pulmonary vascular resistance (122 + 70 dynes s cm(-5)). While PCWP, FEV(1)% predicted, and the minimum oxygen saturation in NREM sleep all independently predicted PH, PCWP was the most important predictor of PH.
We conclude that pulmonary hypertension is commonly seen in patients with OSA with pretibial edema and that pretibial edema is a highly specific sign of PH in OSA patients. Pulmonary hypertension appears to result from an elevated back pressure and diastolic dysfunction with contributions from lung function and nocturnal oxygen saturation.

AB Behavioral data supports the commonsense view that babies elicit different responses than adults do. Behavioral research also has supported the babyface overgeneralization hypothesis that the adaptive value of responding appropriately to babies produces a tendency for these responses to be over-generalized to adults whose facial structure resembles babies. Here we show a neural substrate for responses to babies and babyface overgeneralization in the amygdala and the fusiform face area (FFA). Both regions showed greater percentage BOLD signal change compared with fixation when viewing faces of babies or babyfaced men than maturefaced men. Viewing the first two categories also yielded greater effective connectivity between the two regions. Facial qualities previously shown to elicit strong neural activation could not account for the effects. Babyfaced men were distinguished only by their resemblance to babies. The preparedness to respond to infantile facial qualities generalizes to babyfaced men in perceivers' neural responses just as it does in their behavioral reactions.

AB Background and Purpose-Patients with abnormal hemostasis are not considered candidates for thrombolysis. We analyzed the MERCI/Multi MERCI cohort as an attempt to establish the risks and benefits of thrombectomy in this patient population.
Methods-Two patient groups were identified: Group 1 (n=35): patients with INR >1.7 or PTT >45 seconds or platelet count <100 000/mu L; Group 2 (n=270): patients with INR <= 1.7, PTT <= 45 seconds, and platelet count >= 100 000/mu L. Clinical, radiographic, and revascularization outcomes were subsequently compared.
Results-In Group 1, 20 patients had INR >1.7 (mean: 2.4; range: 1.8 to 4.9), 11 had PTT >45 seconds (mean: 95; range: 46 to 190), and 6 had platelets <100 000/mu L (mean: 63 400; range: 16 000 to 94 000). Two patients had both INR >1.7 and PTT >45 seconds. The two groups did not significantly differ in terms of age, gender, baseline NIHSS scores, intraarterial thrombolytic use/dosage, or occlusion site. Time-to-treatment was slightly earlier in Group 1. There was no significant difference in the rates of revascularization (TIMI 2 to 3: 60% versus 65%), mortality (40% versus 38%), or major symptomatic intracranial hemorrhage (SICH; 8.6% versus 8.5%). Group 2 had higher rates of good clinical outcomes (9% versus 35%; P=0.002). This was likely related to a lower prestroke health status in Group 1 patients. In Group 1, successful revascularization was associated with improved outcomes (P=0.015) and lower mortality (24% versus 64%; P=0.033).
Conclusion-Patients with abnormal hemostasis who undergo thrombectomy do not appear to be at a higher risk for SICH but have lower rates of good outcomes. In this patient group, successful revascularization appears to be associated with improved clinical outcomes and lower mortality. (Stroke. 2009;40:516-522.)

AB Background and Purpose-Previous reports have shown higher in-hospital mortality for patients with acute stroke who arrived on weekends compared with regular workdays. We analyzed the effect of presenting during off-hours, defined as weekends and weeknights (versus weekdays), on in-hospital mortality and on quality of care in the Get With The Guidelines (GWTG)-Stroke program.
Methods-We analyzed data from 187 669 acute ischemic stroke and 34 845 acute hemorrhagic stroke admissions who presented to the emergency departments of 857 hospitals that participated in the GWTG-Stroke program during the 4-year period 2003 to 2007. Off-hour presentation was defined as presentation anytime outside of 7: 00 AM to 6: 00 PM on weekdays. Quality of care was measured using standard GWTG quality indicators covering acute, subacute, and discharge measures. The relationship between off-hour presentation and in-hospital case fatality was examined using generalized estimating equation logistic regression adjusting for demographics, risk factors, arrival mode, and hospital characteristics.
Results-Half of ischemic stroke admissions and 57% of hemorrhagic stroke admissions presented during off-hours. Among ischemic stroke admissions, the in-hospital case fatality rate was 5.8% for off-hour presentation compared with 5.2% for on-hour presentation (P<0.001). For hemorrhagic stroke admissions, in-hospital case fatality was 27.2% for off-hour presentation compared with 24.1% for on-hour presentation (P<0.001). After adjusting for patient-level and hospital-level factors, presentation during off-hours was significantly associated with higher in-hospital mortality for both ischemic stroke (adjusted OR, 1.09; 95% CI, 1.03 to 1.14) and hemorrhagic stroke admissions (adjusted OR, 1.19; 95% CI, 1.12 to 1.27). No differences were observed between off-hour presentation and any of the quality of care measures.
Conclusions-Off-hour presentation was associated with an increased risk of dying in-hospital, although the absolute effect was small for ischemic stroke admissions (0.6% difference; number needed to harm=166) and moderate for hemorrhagic stroke (3.1% difference; number needed to harm=32). Reducing the disparity in hospital-based outcomes for admissions that present during off-hours represents a potential target for quality improvement efforts, although evidence of differences in the quality of care by time of presentation was lacking.

AB Background and Purpose-We recently reported that delayed lithium therapy can improve stroke recovery in rats by augmenting neurovascular remodeling. We tested the hypothesis that lithium can promote the expression of growth factors in brain endothelial cells and astrocytes.
Methods-Human brain microvascular endothelial cells and primary rat cortical astrocytes were exposed to lithium chloride in serum-free medium. We examined 2 representative growth factors: brain-derived neurotrophic factor and vascular endothelial growth factor (VEGF). Cell lysates were collected for Western blot analysis. Conditioned media was analyzed with enzyme-linked immunosorbent assay. SB-216763 and LY294002 were used to assess the roles of the glycogen synthase kinase-3 beta (GSK-3 beta) and PI3-K signaling in the lithium-induced responses.
Results-No consistent responses were observed for brain-derived neurotrophic factor. However, lithium (0.2 to 20 mmol/L) increased the phosphorylation of GSK-3 beta and promoted VEGF secretion in a concentration-dependent manner in both endothelial and astrocyte cells. For endothelial cells, the potent GSK-3 beta inhibitor SB-216763 upregulated VEGF, whereas inhibition of PI3-K with LY294002 suppressed lithium-induced responses in both phospho-GSK-3 beta and VEGF. In contrast, neither inhibition of GSK-3 beta nor inhibition of PI3-K had any detectable effects on VEGF levels in astrocytes.
Conclusions-Lithium promotes VEGF expression through PI3-K/GSK-3 beta-dependent and-independent pathways in brain endothelium and astrocytes, respectively. This growth factor signaling mechanism may contribute to lithium's reported ability to promote neurovascular remodeling after stroke. (Stroke. 2009;40:652-655.)

AB There is much empirical literature on factors for adolescent suicide risk, but body image and disordered eating are rarely included in these models. In the current study, disordered eating and body image were examined as risk factors for suicide ideation since these factors are prevalent in adolescence, particularly for females. It was hypothesized that disordered eating and body image, in addition to depressive symptoms, would contribute to suicide ideation. It was also hypothesized that these relationships would be stronger for females than for males. Structural equation modeling was used to test a model of risk for suicide ideation incorporating the above factors in a sample of 392 high school students. Results indicated that disordered eating contributed to both suicide ideation and depressive symptoms, while body image only contributed to depressive symptoms. Depressive symptoms contributed to suicide ideation. The model was found to be cross-validated with males and females, and no gender differences emerged. Implications of these findings and their importance in constructing future models of adolescent suicide risk are discussed.

DT Article
ID SURGERY
AB Background. Few studies of learning in the health care sector have analyzed measures of process, as opposed to outcomes. We assessed the learning carve for a new cardiac surgical center using precursor events (incidents or circumstances required for the occurrence of adverse outcomes).
Methods. Intraoperative precursor events were recorded prospectively during major adult cardiac operations, categorized by blinded adjudicators, and counted for each case (overall and according to these categories). Trendy in the number of precursor events were analyzed by hospital and by defining 10 equal-sized groups across lime, as were trends ill outcomes obtained from institutional databases. Results from the first 101 cases performed (it a new cardiac surgical site (hospital A) Were compared with 2 established centers.
Results. A steel) reduction in the total number of precursor events over time Was observed in the early experience of hospital A (9.2 +/- 4.9 to 2.0 +/- 1.2 events per case, from first to last decile of time, P(trend) < .0001) compared with qnalitatively stable levels in the other hospitals; this reduction was driven largely by decreases ill the minor Severity (P(trend) < .0001), compensated (P(trend) < .0001), and environment (P(trend) < .0001) categories of Precursor events. No delectable changes over time Were observed in postoperative mortality and complications. No significant improvement was observed in patient comorbid conditions or medical stains over time to explain the trend in hospital.
Conclusion. Analyzing and targeting specific kinds of process-related failures (precursor events) may provide a novel and sensitive means of tracking, deconstructing, and optimizing organizational learning in medicine. (Surgery 2009;145:131-7)

AB An important component of quality healthcare is that it be patient-centered with a focus on the patient, including his or her preferences, values, and beliefs. The goal of this article is to provide a broad overview of patient-centered outcomes in oncologic research. It starts with an introduction to the different types of patient-centered measures including patient satisfaction, decision regret, patient preference, and health-related quality of life. It then offers an overview of survey instrument design and selection. Finally, it provides examples of existing approaches to measurement and previously validated instruments for each type of patient-centered outcome.

ID RADIATION-THERAPY; BONE
AB Background: Giant cell tumors are benign tumors of the bone that most commonly occur at the ends of the long bones; they are rarely found in the spine above the sacrum. The management of patients with giant cell tumors of the spine represents a challenge, and the clinical approach to this problem continues to evolve with improvements in surgical and adjunctive therapies.
Case Description: A 19-year-old woman with localized back pain and a spinal compression deformity was found to harbor a giant cell tumor of the T7 vertebral body. The patient was first treated with arterial embolization of the hypervascular region observed on angiography. Subsequently, the patient underwent a one-stage transthoracic T7 corpectomy followed by anterior spinal reconstruction and stabilization. Postoperatively, the patient's kyphotic deformity was corrected. To optimize local disease control, the patient underwent IMRT delivered to the site of tumor resection. She remains neurologically intact at 1 year postoperatively without evidence of disease recurrence.
Conclusion: The literature and approaches to the management of spinal giant cell tumors are reviewed. (C) 2009 Elsevier Inc. All rights reserved.

AB The mechanism by which deep brain stimulation (DBS) of the subthalamic nucleus (STN) achieves its effects in Parkinson's disease (PD) is not known. In animal models of PD, stimulation and lesioning of the STN have some effects which are the same, but others which differ, in reversing cellular and behavioral changes induced by dopamine depletion. We compared the effects of short-term STN stimulation and lesions upon extracellular levels of dopamine and metabolites using in vivo microdialysis of the dorsal striatum of awake, intact and unilateral 6-hydroxydopamine (60HDA)-lesioned rats. STN stimulation in control rats decreased striatal dopamine levels and caused a relative increase in dopamine metabolism, as expressed by HVA/dopamine and DOPAC/dopamine ratios. This suggests an increase in both vesicular dopamine release (metabolized to HVA), and release from the cytoplasmic dopamine pool (metabolized to DOPAC). STN lesions in control rats increased the HVA/dopamine ratio, also suggesting a relative increase in vesicular dopamine release. These results indicate that STN stimulation and lesioning can affect striatal dopamine metabolism in the intact system. In 60HDA-lesioned rats at baseline, metabolic ratios were markedly decreased as compared with controls. STN lesions of 60HDA-lesioned rats did not affect relative metabolic ratios as compared with baseline levels. In 6-OHDA-lesioned rats, STN stimulation decreased extracellular levels of dopamine, and, to a greater extent, metabolites, resulting in a decrease in metabolic ratios. This further decrease in dopamine turnover with STN stimulation would serve to maintain dopamine levels in the dopamine-depleted striatum, and may account for the therapeutic benefit of DBS in Parkinson's disease.

AB ADAMTS13 cleaves ultralarge von Willebrand factor (VWF) and plays a significant role in vascular biology and thrombotic thrombocytopenic purpura. CD36, a transmembrane protein present on endothelial cells and platelets (PLTs), binds to thrombospondin via three thrombospondin type 1 repeats. ADAMTS13 contains eight thrombospondin type 1 repeats.
An enzyme-linked immunoassay was used to explore the binding of recombinant human CD36 (rHuCD36) to recombinant human ADAMTS13 (rHuADAMTS13). A competition assay between rHuADAMTS13 and recombinant human (rHu)-thrombospondin-2 for binding to CD36 was then performed. Subsequently, binding of rHuADAMTS13 to PLT membrane fragments expressing CD36 (PLT glycoprotein IV) and glycoprotein Ib/IX was assessed. To examine the functional significance of an ADAMTS13-CD36 interaction, ADAMTS13 activity measured by a fluorescence resonance energy transfer assay was investigated in the presence of either rHuCD36 or concentrated PLTs.
rHuCD36 bound to rHuADAMTS13 in a dose-dependent fashion. rHu-thrombospondin-2 competed with ADAMTS13 for CD36 occupancy, but even high concentrations of rHu-thrombospondin-2 failed to completely block binding of rHuADAMTS13 to rHuCD36. rHuADAMTS13 bound to PLT membrane fragments expressing CD36 (PLT glycoprotein IV) in preference to PLT membrane fragments expressing glycoprotein Ib/IX. ADAMTS13 activity was not inhibited by the presence of either rHuCD36 or concentrated PLTs.
rHuADAMTS13 binds to both rHuCD36 and PLT membrane CD36 in vitro. The binding of CD36 to rHuADAMTS13 with retention of its enzymatic activity is consistent with a proposed role for CD36 in localizing ADAMTS13 on the endothelial cell surface where it regulates the cleavage of VWF.

AB Family and twin studies attest to the importance of genetic factors influencing susceptibility to bipolar disorder and to its genetic and phenotypic complexity. Although linkage and candidate gene association studies have repeatedly implicated some chromosome regions and certain genes, they have not produced the level of unambiguous support required to confirm the involvement of any specific gene or sequence variant in the pathogenesis of bipolar disorder. However, strong associations have recently been reported in meta-analyses of genome-wide association studies and the systematic study of structural variation is ongoing. These findings indicate that the study of large, phenotypically well-characterized samples will make an important contribution to delineating the etiology and pathogenesis of bipolar disorder and thereby pave the way for major improvements in clinical management.

AB OBJECTIVES To analyze the relationship between plasma testosterone and estradiol levels on prostate biopsy and radical prostatectomy Gleason scores in a cohort of patients with newly diagnosed prostate cancer.
METHODS Patients with prostate cancer evaluated at the Dana-Farber Cancer Institute from 2001 to 2005 who were enrolled in a prospective sample banking protocol were eligible for this study. Stored plasma was processed for total testosterone, total estradiol, and sex hormone-binding globulin levels using enzyme-linked immunosorbent assays. The frequency of high-grade biopsy and radical prostatectomy Gleason scores (>6) was the primary endpoint. Univariate and multivariate logistic regression analyses were per-formed to determine the relationship between the hormone levels and high-grade Gleason scores while adjusting for sex hormone-binding globulin, age, body mass index, and prostate-specific antigen.
RESULTS A total of 539 patients were included in this study, 199 of whom underwent radical prostatectomy. The median prostate-specific antigen level was 5.1 ng/dL, and 67% of the cancers were not palpable. The Gleason score was 2-6, 7, and 8-10 in 53%, 37%, and 10% of the cancers, respectively. On univariate analysis of the high-grade biopsy and radical prostatectomy Gleason score, the total testosterone, total estradiol, and estradiol-to-testosterone ratio were not significant as continuous or categorical variables. Adjusting these results for sex hormone-binding globulin level, body mass index, age, and prostate-specific antigen level did not change the conclusions, and these results were unchanged when categorizing high-grade prostate cancer as Gleason score 8-10.
CONCLUSIONS No relationship was found between the circulating steroid hormone levels and the Gleason score in this cohort. UROLOGY 73: 356-361, 2009. (C) 2009 Published by Elsevier Inc.

AB Quality-of-care indicators have not yet been defined for patients with bladder cancer. Nonetheless, certain aspects of bladder cancer care can be evaluated to quantify the quality of care delivered. We sought to determine trends in continent urinary diversion to evaluate the adoption of this more optimal reconstruction.
Subjects who underwent radical cystectomy for a primary diagnosis of bladder cancer were identified from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample. We identified covariates independently associated with utilization of continent urinary diversion after radical cystectomy using multivariate logistic regression modeling. We then examined trends in diversion type based on patient and hospital characteristics and examined the impact of hospital volume on use of continent reconstruction.
Our weighted sample included 5,075 subjects (14.3%) who underwent continent urinary diversion and 30,295 subjects (85.7%) who underwent an ileal conduit. Independent correlates of continent diversion included younger age, male gender, having private insurance, and undergoing surgery at an urban teaching hospital. Hospitals performing continent diversions on more than 40% of their cystectomies had a yearly cystectomy volume of 0.8 surgeries. Subjects treated at high-volume hospitals trended toward lower rates of comorbid conditions.
We identified substantial disparities in continent diversion which, based on yearly trends, are unlikely to improve in the near future. Continent reconstructions are not the exclusive domain of high-volume cystectomy centers. Yet efforts to increase rates of this complex reconstruction must concentrate on technique dissemination and better definition of the quality-of-life detriments incurred by cystectomy patients.

AB The Leishmania species present a genetic homology that ranges from 69 to 90%. Because of this homology, heterologous antigens have been used in the immunodiagnosis and vaccine development against Leishmania infections. In the current work, we describe the identification of species-specific and cross-reactive antigens among several New World Leishmania species, using symptomatic and asymptomatic naturally Leishmania chagasi-infected dog sera. Soluble antigens from five strains of New World Leishmania were separated by electrophoresis in SDS-PAGE and immunoblotted. Different proteins were uniquely recognized in the L. chagasi panel by either symptomatic or asymptomatic dog sera suggesting their use as markers for the progression of disease and diagnosis of the initial (sub-clinical) phase of the infection. Cross-reactive antigens were identified using heterologous antigenic panels (L. amazonensis strains PH8 and BH6, L. guyanensis and L. braziliensis). L. guyanensis panel showed the highest cross-reactivity against L. chagasi specific antibodies, suggesting that proteins from this extract might be suitable for the diagnosis of visceral canine leishmaniasis. Interestingly, the 51 and 97 kDa proteins of Leishmania were widely recognized (77.8% to 100%) among all antigenic panels tested, supporting their potential use for immunodiagnosis. Finally, we identified several leishmanial antigens that might be useful for routine diagnosis and seroepidemiological studies of the visceral canine leishmaniasis.

AB The saturated fatty acid palmitate alters normal cell function via disruption of cell signaling, and this effect has been implicated in the end-organ damage associated with dyslipidemia. Neuregulin-1 beta (NRG-1 beta) is a growth and survival factor in cardiac myocytes. We tested the hypothesis that palmitate alters NRG-1 beta signaling and biology in isolated neonatal rat cardiac myocytes. Palmitate treatment inhibited NRG-1 beta activation of the PI3-kinase/Akt pathway in myocytes. We found that the pro-apoptotic activity of palmitate was increased by NRG-1 beta treatment. The effects of palmitate on NRG-1 beta, signaling and Survival were reversed by the mono-unsaturated fatty acid oleate. Under control conditions NRG-1 beta decreases p53 expression in myocytes. In the presence of palmitate, NRG-1 beta caused an increase in p53 expression, bax multimer formation, concurrent with degradation of mdm2, a negative regulator of p53. Thus in the presence of palmitate NRG-1 beta activates pro-apoptotic, rather than pro-survival signaling in cardiac myocytes. (C) 2008 Elsevier Inc. All rights reserved.

AB Inflammatory cytokine interleukin (IL)-6 is elevated in the serum and lungs of patients with pulmonary artery hypertension (PAH). Several animal models of PAH cite the potential role of inflammatory mediators. We investigated role of IL-6 in the pathogenesis of pulmonary vascular disease. Indices of pulmonary vascular remodeling were measured in lung-specific IL-6-overexpressing transgenic mice (Tg(+)) and compared to wild-type (Tg(-)) controls in both normoxic and chronic hypoxic conditions. The Tg(+) mice exhibited elevated right ventricular systolic pressures and right ventricular hypertrophy with corresponding pulmonary vasculopathic changes, all of which were exacerbated by chronic hypoxia. IL-6 overexpression increased muscularization of the proximal arterial tree, and hypoxia enhanced this effect. It also reproduced the muscularization and proliferative arteriopathy seen in the distal arteriolar vessels of PAH patients. The latter was characterized by the formation of occlusive neointimal angioproliferative lesions that worsened with hypoxia and were composed of endothelial cells and T-lymphocytes. IL-6-induced arteriopathic changes were accompanied by activation of proangiogenic factor, vascular endothelial growth factor, the proproliferative kinase extracellular signal-regulated kinase, proproliferative transcription factors c-MYC and MAX, and the antiapoptotic proteins survivin and Bcl-2 and downregulation of the growth inhibitor transforming growth factor-beta and proapoptotic kinases JNK and p38. These findings suggest that IL-6 promotes the development and progression of pulmonary vascular remodeling and PAH through proproliferative antiapoptotic mechanisms. (Circ Res. 2009; 104: 236-244.)

AB It is common in oculomotor and vestibular research to use video or still cameras to acquire data on eye movements. Unfortunately, such data are often contaminated by unwanted motion of the face relative to the camera, especially during experiments in dynamic motion environments. We develop a method for estimating the motion of a camera relative to a highly deformable surface, specifically the movement of a camera relative to the face and eyes. A small rectangular region of interest (ROI) on the face is automatically selected and tracked throughout a set of video frames as a measure of vertical camera translation. The specific goal is to present a process based on a genetic algorithm that selects a suitable ROI for tracking: one whose translation within the camera image accurately matches the actual relative motion of the camera. We find that co-correlation, a statistic describing the time series of a large group of ROIs, predicts the accuracy of the ROIs, and can be used to select the best ROI from a group. After the genetic algorithm finds the best ROIs from a group, it uses recombination to form a new generation of ROIs that inherit properties of the ROIs from the previous generation. We show that the algorithm can select an ROI that will estimate camera translation and determine the direction that the eye is looking with an average accuracy of 0.75 degrees, even with camera translations of 2.5 mm at a viewing distance of 120 mm, which Would cause an error of 11 degrees without correction.

AB The LK131-AMPK signaling pathway serves as a critical cellular sensor coupling energy homeostasis to cell growth, proliferation, and survival. However, how tumor cells suppress this signaling pathway to gain growth advantage under conditions of energy stress is largely unknown. Here, we show that AMPK activation is suppressed in melanoma cells with the B-RAF V600E mutation and that downregulation of B-RAF signaling activates AMPK. We find that in these cells LKB1 is phosphorylated by ERK and Rsk, two kinases downstream of B-RAF, and that this phosphorylation compromises the ability of LKB1 to bind and activate AMPK. Furthermore, expression of a phosphorylation-deficient mutant of LKB1 allows activation of AMPK and inhibits melanoma cell proliferation and anchorage-independent cell growth. Our findings provide a molecular linkage between the LKB1-AMPK and the RAF-MEK-ERK pathways and suggest that suppression of LKB1 function by B-RAF V600E plays an important role in B-RAF V600E-driven tumorigenesis.

AB Aberrations in chromatin dynamics play a fundamental role in tumorigenesis, yet relatively little is known of the molecular mechanisms linking histone lysine methylation to neoplastic disease. ING4 (Inhibitor of Growth 4) is a native subunit of an HBO1 histone acetyltransferase (HAT) complex and a tumor suppressor protein. Here we show a critical role for specific recognition of histone H3 trimethylated at lysine 4 (H3K4me3) by the ING4 PHD finger in mediating ING4 gene expression and tumor suppressor functions. The interaction between ING4 and H3K4me3 augments HBO1 acetylation activity on H3 tails and drives H3 acetylation at ING4 target promoters. Further, ING4 facilitates apoptosis in response to genotoxic stress and inhibits anchorage-independent cell growth, and these functions depend on ING4 interactions with H3K4me3. Together, our results demonstrate a mechanism for brokering crosstalk between H3K4 methylation and H3 acetylation and reveal a molecular link between chromatin modulation and tumor suppressor mechanisms.

AB Eating disturbances continue to grow among college students, and researchers have begun to investigate factors that may lead to abnormal eating behaviors in this population. Recent research has also suggested that excessive exercise can become a compulsive behavior that may affect psychological health. The aim of this exploratory study was to evaluate the relationships between both compulsive eating and exercise, and demographic and clinical variables in a college population. Participants were 589 undergraduates (mean age 20 years) recruited during a mental health screening at two different campuses. Participants completed a screening package of measures including a questionnaire about socio-demographic data, the Beck Depression Inventory (BDI), the Beck Hopelessness Scale (BHS), the Consumptive Habits Questionnaire (CHQ), the Modified Overt Aggression Scale-Self-rated version (MOAS), and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short version (QLESQ). A prevalence rate of 7.2% was found for compulsive eating and 18.1% for compulsive exercise, as measured by the CHQ. Only 11 participants (1.9%) reported both compulsive eating and exercise. There was no significant relationship between compulsive eating and compulsive exercise. The results suggest that college students may represent a group at high risk of developing abnormal eating behaviors and compulsive exercise. (C) 2007 Elsevier Ireland Ltd. All rights reserved.

Yet little is known about the processes by which platelet microparticles are generated in vivo. We now characterize microparticles derived directly from megakaryocytes. Video microscopy of live mouse megakaryocytes demonstrated that microparticles form as submicron beads along the lengths of slender, unbranched micropodia. These microparticles are CD41(+), CD42b(+), and express surface phosphatidylserine. Megakaryocyte microparticle generation is resistant to inhibition of microtubule assembly, which is critical to platelet formation, and augmented by inhibition of actin polymerization. To determine whether circulating microparticles are derived primarily from activated platelets or megakaryocytes, we identified markers that distinguish between these 2 populations. CD62P and LAMP-1 were found only on mouse microparticles from activated platelets. In contrast, full-length filamin A was found in megakaryocyte-derived microparticles, but not microparticles from activated platelets. Circulating microparticles isolated from mice were CD62P(-), LAMP-1(-) and expressed fulllength filamin A, indicating a megakaryocytic origin. Similarly, circulating microparticles isolated from healthy volunteers were CD62P(-) and expressed full-length filamin A. Cultured human megakaryocytes elaborated microparticles that were CD41(+), CD42b(+), and express surface phosphatidylserine. These results indicate that direct production by megakaryocytes represents a physiologic means to generate circulating platelet microparticles. (Blood. 2009;113:1112-1121)

AB Background: Obesity is an established and modifiable risk factor for urinary incontinence, but conclusive evidence for a beneficial effect of weight loss on urinary incontinence is lacking.
Methods: We randomly assigned 338 overweight and obese women with at least 10 urinary-incontinence episodes per week to an intensive 6-month weight-loss program that included diet, exercise, and behavior modification (226 patients) or to a structured education program (112 patients).
Results: The mean (+/-SD) age of the participants was 53+/-11 years. The body-mass index (BMI) (the weight in kilograms divided by the square of the height in meters) and the weekly number of incontinence episodes as recorded in a 7-day diary of voiding were similar in the intervention group and the control group at baseline (BMI, 36+/-6 and 36+/-5, respectively; incontinence episodes, 24+/-18 and 24+/-16, respectively). The women in the intervention group had a mean weight loss of 8.0% (7.8 kg), as compared with 1.6% (1.5 kg) in the control group (P<0.001). After 6 months, the mean weekly number of incontinence episodes decreased by 47% in the intervention group, as compared with 28% in the control group (P=0.01). As compared with the control group, the intervention group had a greater decrease in the frequency of stress-incontinence episodes (P=0.02), but not of urge-incontinence episodes (P=0.14). A higher proportion of the intervention group than of the control group had a clinically relevant reduction of 70% or more in the frequency of all incontinence episodes (P<0.001), stress-incontinence episodes (P=0.009), and urge-incontinence episodes (P=0.04).
Conclusions: A 6-month behavioral intervention targeting weight loss reduced the frequency of self-reported urinary-incontinence episodes among overweight and obese women as compared with a control group. A decrease in urinary incontinence may be another benefit among the extensive health improvements associated with moderate weight reduction. (ClinicalTrials.gov number, NCT00091988.)

AB Background: Surgery has become an integral part of global health care, with an estimated 234 million operations performed yearly. Surgical complications are common and often preventable. We hypothesized that a program to implement a 19-item surgical safety checklist designed to improve team communication and consistency of care would reduce complications and deaths associated with surgery.
Methods: Between October 2007 and September 2008, eight hospitals in eight cities (Toronto, Canada; New Delhi, India; Amman, Jordan; Auckland, New Zealand; Manila, Philippines; Ifakara, Tanzania; London, England; and Seattle, WA) representing a variety of economic circumstances and diverse populations of patients participated in the World Health Organization's Safe Surgery Saves Lives program. We prospectively collected data on clinical processes and outcomes from 3733 consecutively enrolled patients 16 years of age or older who were undergoing noncardiac surgery. We subsequently collected data on 3955 consecutively enrolled patients after the introduction of the Surgical Safety Checklist. The primary end point was the rate of complications, including death, during hospitalization within the first 30 days after the operation.
Results: The rate of death was 1.5% before the checklist was introduced and declined to 0.8% afterward (P=0.003). Inpatient complications occurred in 11.0% of patients at baseline and in 7.0% after introduction of the checklist (P<0.001).
Conclusions: Implementation of the checklist was associated with concomitant reductions in the rates of death and complications among patients at least 16 years of age who were undergoing noncardiac surgery in a diverse group of hospitals.

AB Objective: Immunosuppression may increase risk for some skin cancers. We evaluated skin cancer epidemiology among persons with AIDS.
Design: We linked data from population-based US AIDS and cancer registries to evaluate risk of nonkeratinocytic skin cancers (melanoma, Merkel cell carcinoma, and appendageal carcinomas, including sebaceous carcinoma) in 497 142 persons with AIDS.
Methods: Standardized incidence ratios (SIRs) were calculated to relate skin cancer risk to that in the general population. We used logistic regression to compare risk according to demographic factors, CD4 cell count, and a geographic index of ultraviolet radiation exposure.
Results: From 60 months before to 60 months after AIDS onset, persons with AIDS had elevated risks of melanoma (SIR=1.3, 95% confidence interval 1.1-1.4, n=292 cases) and, more strongly, of Merkel cell carcinoma (SIR=11, 95% confidence interval 6.3-17, n=17) and sebaceous carcinoma (SIR=8.1, 95% confidence interval 3.2-17, n=7). Risk for appendageal carcinomas increased with progressive time relative to AIDS onset (P trend 0.03). Risk of these skin cancers was higher in non-Hispanic whites than other racial/ethnic groups, and melanoma risk was highest among men who have sex with men. Melanoma risk was unrelated to CD4 cell count at AIDS onset (P=0.32). Risks for melanoma and appendageal carcinomas rose with increasing ultraviolet radiation exposure (P trend <10 (4) and P trend -10 (3), respectively).
Conclusion: Among persons with AIDS, there is a modest excess risk of melanoma, which is not strongly related to immunosuppression and may relate to ultraviolet radiation exposure. In contrast, the greatly increased risks for Merkel cell and sebaceous carcinoma suggest an etiologic role for immunosuppression.

AB Context Women treated with chest radiation for a pediatric malignancy have a significantly increased risk of breast cancer at a young age and are recommended to have an annual screening mammogram starting at age 25 years or 8 years after radiation, whichever occurs last.
Objective To characterize the breast cancer surveillance practices among female pediatric cancer survivors who were treated with chest radiation and identify correlates of screening.
Design, Setting, and Participants Between June 2005 and August 2006, a 114-item questionnaire was administered to a random sample of 625 women aged 25 through 50 years who had survived pediatric cancer, who had been treated with chest radiation, and who were participating in the Childhood Cancer Survivor Study (CCSS), a North American cohort of long- term survivors diagnosed from 1970- 1986. Comparisons were made with similarly aged pediatric cancer survivors not treated with chest radiation ( n= 639) and the CCSS siblings cohort ( n= 712).
Main Outcome Measure Screening mammogram within the previous 2 years.
Results Of 1976 cancer survivors and siblings who were contacted, 87.9% participated. Among the 551 women with a history of chest radiation, 55% reported a screening mammogram in the past 2 years (ages 25- 39 years, 36.5%; 95% confidence interval [ CI], 31.0%-42.0%; ages 40- 50 years, 76.5%; 95% CI, 71.3%- 81.7%). In comparison, 40.5% of survivors without chest radiation and 37.0% of CCSS siblings reported a screening mammogram in the same time interval. Notably, among women with a history of chest radiation, 47.3% ( 95% CI; 41.6%- 53.0%) of those younger than 40 years had never had a mammogram and only 52.6% ( 95% CI; 46.4%- 58.8%) of women aged 40 through 50 years were being regularly screened ( 2 mammograms within 4 years). Screening rates were higher among women who reported a physician recommendation than those who did not ( ages 25- 39 years, 76.0% vs 17.6%; ages 40- 50 years, 87.3% vs 58.3%). In multivariate models, the association was particularly strong for younger women( ages25- 39 years, prevalence ratio [ PR], 3.0; 95% CI, 2.0- 4.0; ages 40- 50 years, PR, 1.3; 95% CI, 1.1- 1.6).
Conclusions In this cohort of women who had childhood cancer treated with chest radiation, 63.5% of those aged 25 through 39 years and 23.5% of those aged 40 through 50 years had not had mammography screening for breast cancer within the previous 2 years despite a guideline recommendation that survivors of childhood cancer who were treated with chest radiation should undergo annual screening mammography.

AB Phagocytosis, which is essential for the immune response to pathogens, is initiated by specific interactions between pathogens and cell surface receptors expressed by phagocytes. This study identifies triggering receptor expressed on myeloid cells 2 (TREM-2) and its signaling counterpart DAP12 as a molecular complex that promotes phagocytosis of bacteria. Expression of TREM-2-DAP12 enables nonphagocytic Chinese hamster ovary cells to internalize bacteria. This function depends on actin cytoskeleton dynamics and the activity of the small guanosine triphosphatases Rac and Cdc42. Internalization also requires src kinase activity and tyrosine phosphorylation. In bone marrow-derived macrophages, phagocytosis is decreased in the absence of DAP12 and can be restored by expression of TREM-2-DAP12. Depletion of TREM-2 inhibits both binding and uptake of bacteria. Finally, TREM-2-dependent phagocytosis is impaired in Syk-deficient macrophages. This study highlights a novel role for TREM-2-DAP12 in the immune response to bacterial pathogens.

AB The anterior-posterior axis of the mouse embryo is established by formation of distal visceral endoderm (DVE) and its subsequent migration. The precise mechanism of DVE formation has remained unknown, however. Here we show that bone morphogenetic protein (BMP) signaling plays dual roles in DVE formation. BMP signaling is required at an early stage for differentiation of the primitive endoderm into the embryonic visceral endoderm (VE), whereas it inhibits DVE formation, restricting it to the distal region, at a later stage. A Smad2-activating factor such as Activin also contributes to DVE formation by generating a region of VE positive for the Smad2 signal and negative for Smad1 signal. DVE is thus formed at the distal end of the embryo, the only region of VE negative for the Smad1 signal and positive for Smad2 signal. An inverse relation between the level of phosphorylated Smad1 and that of phosphorylated Smad2 in VE suggests an involvement of antagonism between Smad1- and Smad2-mediated signaling.

AB Background: Gene microarray technology is an effective tool to investigate the simultaneous activity of multiple cellular pathways from hundreds to thousands of genes. However, because data in the colossal amounts generated by DNA microarray technology are usually complex, noisy, high-dimensional, and often hindered by low statistical power, their exploitation is difficult. To overcome these problems, two kinds of unsupervised analysis methods for microarray data: principal component analysis (PCA) and independent component analysis (ICA) have been developed to accomplish the task. PCA projects the data into a new space spanned by the principal components that are mutually orthonormal to each other. The constraint of mutual orthogonality and second-order statistics technique within PCA algorithms, however, may not be applied to the biological systems studied. Extracting and characterizing the most informative features of the biological signals, however, require higher-order statistics.
Results: ICA is one of the unsupervised algorithms that can extract higher-order statistical structures from data and has been applied to DNA microarray gene expression data analysis. We performed FastICA method on DNA microarray gene expression data from Alzheimer's disease (AD) hippocampal tissue samples and consequential gene clustering. Experimental results showed that the ICA method can improve the clustering results of AD samples and identify significant genes. More than 50 significant genes with high expression levels in severe AD were extracted, representing immunity-related protein, metal-related protein, membrane protein, lipoprotein, neuropeptide, cytoskeleton protein, cellular binding protein, and ribosomal protein. Within the aforementioned categories, our method also found 37 significant genes with low expression levels. Moreover, it is worth noting that some oncogenes and phosphorylation- related proteins are expressed in low levels. In comparison to the PCA and support vector machine recursive feature elimination (SVM-RFE) methods, which are widely used in microarray data analysis, ICA can identify more AD-related genes. Furthermore, we have validated and identified many genes that are associated with AD pathogenesis.
Conclusion: We demonstrated that ICA exploits higher-order statistics to identify gene expression profiles as linear combinations of elementary expression patterns that lead to the construction of potential AD-related pathogenic pathways. Our computing results also validated that the ICA model outperformed PCA and the SVM-RFE method. This report shows that ICA as a microarray data analysis tool can help us to elucidate the molecular taxonomy of AD and other multifactorial and polygenic complex diseases.

AB Background-In February 2002, the Department of Veterans Affairs (VA) increased copayments from $2 to $7 per 30-day drug supply of each medication for many veterans. We examined the impact of the copayment increase on lipid-lowering medication adherence.
Methods and Results-This quasiexperimental study used electronic records of 5604 veterans receiving care at the Philadelphia VA Medical Center from November 1999 to April 2004. The all copayment group included veterans subject to copayments for all drugs with no annual cap. Veterans subject to copayments for drugs only if indicated for a non-service-connected condition with an annual cap of $840 for out-of-pocket costs made up the some copayment group. Veterans who remained copayment exempt formed a natural control group (no copayment group). Patients were identified as adherent if the proportion of days covered with lipid-lowering medications was >= 80%. Patients were identified as having a continuous gap if they had at least 1 continuous episode with no lipid-lowering medications for >= 90 days. A difference-in-difference approach compared changes in lipid-lowering medication adherence during the 24 months before and after copayment increase among veterans subject to the copayment change with those who were not. Adherence declined in all 3 groups after the copayment increase. However, the percentage of patients who were adherent (proportion of days covered >= 80%) declined significantly more in the all copayment (- 19.2%) and some copayment (- 19.3%) groups relative to the exempt group (- 11.9%). The incidence of a continuous gap increased significantly at twice the rate in both copayment groups (all copayment group, 24.6%; some copayment group, 24.1%) as the exempt group (11.7%). Compared with the exempt group, the odds of having a continuous gap in the after relative to the before period were significantly higher in both the all copayment group (odds ratio, 3.04; 95% confidence interval, 2.29 to 4.03) and the some copayment group (odds ratio, 1.85; 95% confidence interval, 1.43 to 2.40). Similar results were seen in subgroups of patients at high risk for coronary heart disease, high medication users, and elderly veterans.
Conclusion-The copayment increase adversely affected lipid-lowering medication adherence among veterans, including those at high coronary heart disease risk. (Circulation. 2009; 119: 390-397.)

AB Background-Ventricular expression of phosphodiesterase-5 (PDE5), an enzyme responsible for cGMP catabolism, is increased in human right ventricular hypertrophy, but its role in left ventricular (LV) failure remains incompletely understood. We therefore measured LV PDE5 expression in patients with advanced systolic heart failure and characterized LV remodeling after myocardial infarction in transgenic mice with cardiomyocyte-specific overexpression of PDE5 (PDE5-TG).
Methods and Results-Immunoblot and immunohistochemistry techniques revealed that PDE5 expression was greater in explanted LVs from patients with dilated and ischemic cardiomyopathy than in control hearts. To evaluate the impact of increased ventricular PDE5 levels on cardiac function, PDE5-TG mice were generated. Confocal and immunoelectron microscopy revealed increased PDE5 expression in cardiomyocytes, predominantly localized to Z-bands. At baseline, myocardial cGMP levels, cell shortening, and calcium handling in isolated cardiomyocytes and LV hemodynamic measurements were similar in PDE5-TG and wild-type littermates. Ten days after myocardial infarction, LV cGMP levels had increased to a greater extent in wild-type mice than in PDE5-TG mice (P < 0.05). Ten weeks after myocardial infarction, LV end-systolic and end-diastolic volumes were larger in PDE5-TG than in wild-type mice (57 +/- 5 versus 39 +/- 4 and 65 +/- 6 versus 48 +/- 4 mu L, respectively; P < 0.01 for both). LV systolic dysfunction and diastolic dysfunction were more marked in PDE5-TG than in wild-type mice, associated with enhanced hypertrophy and reduced contractile function in isolated cardiomyocytes from remote myocardium.
Conclusions-Increased PDE5 expression predisposes mice to adverse LV remodeling after myocardial infarction. Increased myocardial PDE5 expression in patients with advanced cardiomyopathy may contribute to the development of heart failure and represents an important therapeutic target.

AB Background-Vascular disease can manifest as stenotic plaques or ectatic aneurysms, although the mechanisms culminating in these divergent disease manifestations remain poorly understood. T-helper type 1 cytokines, including interferon-gamma and CXCL10, have been strongly implicated in atherosclerotic plaque development.
Methods and Results-Here, we specifically examined their role in the formation of abdominal aortic aneurysms in the angiotensin II-induced murine model. Unexpectedly, we found increased suprarenal aortic diameters, abdominal aortic aneurysm incidence, and aneurysmal death in apolipoprotein E- and interferon-gamma-deficient (Apoe(-/-)/Ifng(-/-)) mice compared with Apoe(-/-) controls, although atherosclerotic luminal plaque formation was attenuated. The interferon-gamma-inducible T-cell chemoattractant CXCL10 was highly induced by angiotensin II infusion in Apoe(-/-) mice, but this induction was markedly attenuated in Apoe(-/-)/Ifng(-/-) mice. Apoe(-/-)/Cxcl10(-/-) mice had decreased luminal plaque but also increased aortic size, worse morphological grades of aneurysms, and a higher incidence of death due to aortic rupture than Apoe(-/-) controls. Furthermore, abdominal aortic aneurysms in Apoe(-/-)/Cxcl10(-/-) mice were enriched for non-T-helper type 1-related signals, including transforming growth factor-beta 1. Treatment of Apoe(-/-)/Cxcl10(-/-) mice with anti-transforming growth factor-beta neutralizing antibody diminished angiotensin II-induced aortic dilation.
Conclusions-The present study defines a novel pathway in which interferon-gamma and its effector, CXCL10, contribute to divergent pathways in abdominal aortic aneurysm versus plaque formation, inhibiting the former pathology but promoting the latter. Thus, efforts to develop antiinflammatory strategies for atherosclerosis must carefully consider potential effects on all manifestations of vascular disease. (Circulation. 2009; 119: 426-435.)

AB Background-A potentially strong association exists between Chlamydia pneumoniae and atherosclerosis, but the clinical benefits of antibiotic therapy have not been demonstrated. Preliminary studies of antibiotic therapy in peripheral artery disease have shown a decreased need for revascularization and improved walking ability. The objective of this phase-III trial was to assess the effect of a potent anti-Chlamydial agent, rifalazil, on peak walking time in patients with symptomatic peripheral artery disease.
Methods and Results-Patients with intermittent claudication secondary to peripheral artery disease who were seropositive for C pneumoniae were randomized to 25 mg rifalazil once weekly for 8 weeks or matching placebo. Two hundred ninety-seven patients were enrolled from 3 countries and were followed up for 1 year. The mean +/- SD ankle brachial index at baseline was 0.63 +/- 0.16. The primary end point, change from baseline in log peak walking time on a graded treadmill, was assessed 180 days after randomization. Secondary end points included changes in claudication onset time and quality of life, assessed with the Walking Impairment Questionnaire and the Short Form Medical Outcomes 36. No benefit of rifalazil therapy was found in the primary or any secondary end point among this cohort of patients with peripheral artery disease. The group treated with rifalazil improved their peak walking times by 23% (95% confidence interval, 15 to 31) from baseline to day 180, whereas the placebo group improved by 18% (95% confidence interval, 11 to 26; P = 0.38). Peak walking time, claudication onset time, Walking Impairment Questionnaire, and Short Form Medical Outcomes 36 showed no treatment-by-time interaction during the 360-day study period. Thirty-two adjudicated cardiovascular events occurred, 16 in each treatment group.
Conclusions-Rifalazil did not improve exercise performance or quality of life in patients with intermittent claudication. No safety concerns were identified. Given the very small effect size, it is unlikely that larger studies would demonstrate a symptomatic benefit of this therapy in peripheral artery disease. (Circulation. 2009; 119: 452-458.)

TI Coronary Calcium Predicts Events Better With Absolute Calcium Scores

AB Objectives In this study, we aimed to establish whether age-sex-specific percentiles of coronary artery calcium (CAC) predict cardiovascular outcomes better than the actual (absolute) CAC score.
Background The presence and extent of CAC correlates with the overall magnitude of coronary atherosclerotic plaque burden and with the development of subsequent coronary events.
Methods MESA (Multi-Ethnic Study of Atherosclerosis) is a prospective cohort study of 6,814 asymptomatic participants followed for coronary heart disease (CHD) events including myocardial infarction, angina, resuscitated cardiac arrest, or CHD death. Time to incident CHD was modeled with Cox regression, and we compared models with percentiles based on age, sex, and/or race/ethnicity to categories commonly used (0, 1 to 100, 101 to 400, 400 + Agatston units).
Results There were 163 (2.4%) incident CHD events (median follow-up 3.75 years). Expressing CAC in terms of age- and sex-specific percentiles had significantly lower area under the receiver-operating characteristic curve (AUC) than when using absolute scores (women: AUC 0.73 versus 0.76, p = 0.044; men: AUC 0.73 versus 0.77, p < 0.001). Akaike's information criterion indicated better model fit with the overall score. Both methods robustly predicted events (> 90th percentile associated with a hazard ratio [HR] of 16.4, 95% confidence interval [CI]: 9.30 to 28.9, and score > 400 associated with HR of 20.6, 95% CI: 11.8 to 36.0). Within groups based on age-, sex-, and race/ethnicity-specific percentiles there remains a clear trend of increasing risk across levels of the absolute CAC groups. In contrast, once absolute CAC category is fixed, there is no increasing trend across levels of age-, sex-, and race/ethnicity-specific categories. Patients with low absolute scores are low-risk, regardless of age-, sex-, and race/ethnicity-specific percentile rank. Persons with an absolute CAC score of > 400 are high risk, regardless of percentile rank.
Conclusions Using absolute CAC in standard groups performed better than age-, sex-, and race/ethnicity-specific percentiles in terms of model fit and discrimination. We recommend using cut points based on the absolute CAC amount, and the common CAC cut points of 100 and 400 seem to perform well.

AB In recent years, accumulating evidence has suggested that vascular risk factors contribute to Alzheimer disease ( AD). Vascular dementia had been traditionally considered secondary to stroke and vascular disease. It has been traditionally distinguished from AD, considered to be a purely neurodegenerative form of dementia. However, in light of this more recent literature, it appears that there is a spectrum: ranging from patients with pure vascular dementia to patients with pure AD and including a large majority of patients with contributions from both Alzheimer and vascular pathologies. In this article, we discuss the impact of vascular risk factors on AD and its consequences at the individual level and at the population level by highlighting the concept of attributable risk. We then discuss the key questions and next steps involved in designing a therapeutic trial to control vascular risk factors for the prevention of dementia. Neurology (R) 2009; 72:368-374

TI Education Research: Neurology residency training in the new millennium
SO NEUROLOGY
LA English
DT Editorial Material
AB Objective: To survey adult neurology program directors (ANPD) to identify their most pressing needs at a time of dramatic change in neurology resident education.
Methods: All US ANPD were surveyed in 2007 using an instrument adjusted from a 1999 survey instrument. The goal was to characterize current program content, the institution and evaluation of the core competencies, program director characteristics, program director support, the institution of work duty hour requirements, resident support, and the curriculum needs of program directors and programs.
Results: A response rate of 82.9% was obtained. There is a significant disconnect between administration time spent by ANPD and departmental/institutional support of this, with ANPD spending approximately 35% of a 50-hour week on administration with only 16.7% salary support. Rearrangement of rotations or services has been the most common mode for ANPD to deal with work duty hour requirements, with few programs employing mid level providers. Most ANPD do not feel work duty hour reform has improved resident education. More residents are entering fellowships following graduation than documented in the past. Curriculum deficiencies still exist for ANPD to meet all Neurology Program Requirements, especially for nontraditional neurology topics outside the conventional bounds of clinical neurology (e. g., practice management). Nearly one quarter of neurology residency programs do not have a meeting or book fund for every resident in the program.
Conclusions: Adult neurology program directors (ANPDs) face multiple important financial and organizational hurdles. At a time of increasing complexity in medical education, ANPDs need more institutional support. Neurology (R) 2009; 72: e15-e20

AB Dicer is central to the RNA interference (RNAi) pathway, because it is required for processing of double-stranded RNA (dsRNA) precursors into small RNA effector molecules. In principle, any long dsRNA could serve as a substrate for Dicer. The X inactive specific transcript (Xist) is an untranslated RNA that is required for dosage compensation in mammals. It coats and silences 1 of the 2 X chromosomes in female cells and initiates a chromosomewide change in chromatin structure that includes the recruitment of Polycomb proteins, but it is largely unknown how Xist RNA mediates these processes. To investigate a potential link between the RNAi pathway and X inactivation, we generated and analyzed Dicer-deficient embryonic stem (ES) cells. In the absence of Dicer, coating by Xist RNA, initiation of silencing, and recruitment of Polycomb proteins occur normally. Dicer ablation had modest effects on the steady-state levels of spliced Xist RNA. Together our data indicate that the RNAi machinery is not essential for the initiation of X inactivation.

AB We examined the status of the neural network mediating the default mode of brain function, which typically exhibits greater activation during rest than during task, in patients in the early phase of schizophrenia and in young first-degree relatives of persons with schizophrenia. During functional MRI, patients, relatives, and controls alternated between rest and performance of working memory (WM) tasks. As expected, controls exhibited task-related suppression of activation in the default network, including medial prefrontal cortex (MPFC) and posterior cingulate cortex/precuneus. Patients and relatives exhibited significantly reduced task-related suppression in MPFC, and these reductions remained after controlling for performance. Increased task-related MPFC suppression correlated with better WM performance in patients and relatives and with less psychopathology in all 3 groups. For WM task performance, patients and relatives had greater activation in right dorsolateral prefrontal cortex (DLPFC) than controls. During rest and task, patients and relatives exhibited abnormally high functional connectivity within the default network. The magnitudes of default network connectivity during rest and task correlated with psychopathology in the patients. Further, during both rest and task, patients exhibited reduced anticorrelations between MPFC and DLPFC, a region that was hyperactivated by patients and relatives during WM performance. Among patients, the magnitude of MPFC task suppression negatively correlated with default connectivity, suggesting an association between the hyperactivation and hyperconnectivity in schizophrenia. Hyperactivation (reduced task-related suppression) of default regions and hyperconnectivity of the default network may contribute to disturbances of thought in schizophrenia and risk for the illness.

CANCER; GROWTH; AKT; EXPRESSION; RAPAMYCIN; MODEL; PTEN
AB The mammalian target of rapamycin (mTOR) is a crucial effector in a complex signaling network commonly disrupted in cancer. mTOR exerts its multiple functions in the context of two different multiprotein complexes: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). Loss of the tumor suppressor PTEN (phosphatase and tensin homolog deleted from chromosome 10) can hyperactivate mTOR through AKT and represents one of the most frequent events in human prostate cancer. We show here that conditional inactivation of mTor in the adult mouse prostate is seemingly inconsequential for this postmitotic tissue. Conversely, inactivation of mTor leads to a marked suppression of Pten loss-induced tumor initiation and progression in the prostate. This suppression is more pronounced than that elicited by the sole pharmacological abrogation of mTORC1. Acute inactivation of mTor in vitro also highlights the differential requirement of mTor function in proliferating and transformed cells. Collectively, our data constitute a strong rationale for developing specific mTOR inhibitors targeting both mTORC1 and mTORC2 for the treatment of tumors triggered by PTEN deficiency and aberrant mTOR signaling.

AB Liver transplantation is currently the only established treatment of end-stage liver disease, but it is limited by a severe shortage of viable donor livers. Donors after cardiac death (DCD) are an untapped source that could significantly increase the pool of available livers. Preservation of these DCD livers by conventional static cold storage (SCS) is associated with an unacceptable risk of primary nonfunction and delayed graft failure. Normothermic extracorporeal liver perfusion (NELP) has been suggested as an improvement over SCS. Livers recovered from male Lewis rats were subjected to 1 hr of warm ischemia and preserved with 5 hr of SCS or NELP, and transplanted into syngeneic recipients. As additional controls, non-ischemic livers preserved with 6 hr of SCS or NELP and unpreserved ischemic livers were transplanted. After NELP, ischemically damaged livers could be orthotopically transplanted into syngeneic recipients with 92% survival (n = 13) after 4 weeks, which was comparable with control animals that received healthy livers preserved by SCS (n=9) or NELP (n=11) for 6 hr. On the other hand, animals from ischemia/SCS control group all died within 12 hr postoperatively (n=6). Similarly, animals that received ischemic livers without preservation all died within 24: hr after transplantation (n=6). These results suggest that NELP has the potential to reclaim warm ischemic livers that would not be transplantable otherwise. The rat model in this study is a useful platform to further optimize NELP as a method of recovery and preservation of DCD livers.

GENE-EXPRESSION; TUMOR CELLS; ASSOCIATION; CYCLOOXYGENASE
AB Background: The use of aspirin and other nonsteroidal anti-inflammatory drugs ( NSAIDs) is widespread for treatment of common symptoms such as headaches, muscular pain, and inflammation. In addition, the chemopreventive use of NSAIDs is increasingly common for heart disease and colon cancer. Evidence of a protective association with breast cancer risk has been inconsistent, and few data exist for premenopausal women.
Methods: We assessed the associations for use of aspirin, other NSAIDs, and acetaminophen with breast cancer risk among premenopausal women in the prospective Nurses' Health Study II. In total, 112 292 women, aged 25 to 42 years and free of cancer in 1989, were followed up until June 2003. Multivariate relative risks and 95% confidence intervals were calculated by Cox proportional hazards models, adjusting for age and other important breast cancer risk factors.
Results: Overall, 1345 cases of invasive premenopausal breast cancer were documented. Regular use of aspirin (>= 2 times per week) was not significantly associated with breast cancer risk ( relative risk, 1.07; 95% confidence interval, 0.89-1.29). Regular use of either non-aspirin NSAIDs or acetaminophen also was not consistently associated with breast cancer risk. Results did not vary by frequency ( days per week), dose ( tablets per week), or duration of use. Furthermore, associations with each drug category did not vary substantially by estrogen and progesterone receptor status of the tumor.
Conclusion: These data suggest that the use of aspirin, other NSAIDs, and acetaminophen is not associated with a reduced risk of breast cancer among premenopausal women.

AB Purpose: Acute anterior uveitis (AAU) is the most common form of uveitis and is thought to be autoimmune in nature. Recent studies have described genes that act as master controllers of autoimmunity. Protein tyrosine phosphatase type 22 (PTPN22) and Cytotoxic T lymphocyte antigen-4 (CTLA-4) are two of these genes, and single nucleotide polymorphisms (SNPs) in the genes encoding these molecules have been associated with several autoimmune diseases. In this study we have analyzed SNPs in PTPN22 and CTLA-4 in patients with AAU.
Methods: The functional protein tyrosine phosphatase type 22 (PTPN22) SNP (R620W rs2476601, 1858C/T), and two CTLA-4 SNPs (rs5742909, -318C/T and rs231775, 49A/G) were analyzed in 140 patients with AAU and 92 healthy controls by sequence-specific primer-polymerase chain reaction (SSP-PCR). Data was analyzed by chi(2) analysis and Fisher's exact test.
Results: There was no significant association between PTPN22 620W, CTLA-4 -318C/T, or CTLA-4 49A/G and AAU. Similarly, there was no association with the three SNPs when patients were classified by race or gender. Finally, there was no association with the presence of ankylosing spondylitis in the patient cohort.
Conclusions: The data do not support an association between SNPs in PTPN22 and CTLA-4, genes regarded as genetic master switches of autoimmunity. This raises the issue of the etiology of AAU and the possibility that it should be regarded as an autoinflammatory rather than an autoimmune condition.

AB Mitochondrial dysfunction has been linked to etiology of insulin resistance, however the mechanism remains unknown. In this study we investigated whether mitochondrial dysfunction induced by cyanide p-trifluoromethoxyphenyl-hydrazone (FCCP) alters insulin sensitivity in 3T3-L1 adipocytes and which cellular signaling molecules might be involved. Fully differentiated 3T3-L1 adipocytes were treated with 10 mu M FCCP for 1 h, resulting in increased serine-307 phosphorylation of IRS-1 and decreased insulin-stimulated tyrosine phosphorylation, association of p85 alpha subunit of phosphatidylinositol 3-kinase (PI 3-kinase) with IRS-1, decreased insulin-stimulated PI 3-kinase activity and H-3-2-deoxyglucose (2DOG) uptake. A partial (46%) knockdown of JNK1 blocked FCCP-induced serine phosphorylation of IRS-1 and restored insulin-stimulated tyrosine phosphorylation of IRS-1, association of p85 alpha subunit of PI 3-kinase with IRS-1. activation of PI 3-kinase, and stimulation of 2DOG uptake. Thus, FCCP-induced mitochondrial dysfunction may cause insulin resistance that is ameliorated by reduction of JNK1 expression. (C) 2008 Elsevier Inc. All rights reserved.

AB We examined in HepG2 cells whether glucose-induced changes in AMP-activated protein kinase (AMPK) activity could be mediated by SIRT1, an NAD(+)-dependent histone/protein deacetylase that has been linked to the increase in longevity caused by caloric restriction. Incubation with 25 vs. 5 mM glucose for 6 h concurrently diminished the phosphorylation of AMPK (Thr 172) and ACC (Ser 79), increased lactate release, and decreased the abundance and activity of SIRT1. In contrast, incubation with pyruvate (0.1 and 1 mM) for 2 h increased AMPK phosphorylation and SIRT1 abundance and activity. The putative SIRT1 activators resveratrol and quercetin also increased AMPK phosphorylation. None of the tested compounds (low or high glucose, pyruvate, and resveratrol) significantly altered the AMP/ATP ratio. Collectively, these findings raise the possibility that glucose-induced changes in AMPK are linked to alterations in SIRT1 abundance and activity and possibly cellular redox state.

AB Penetrating limb injuries are common and usually heal without long-lasting effects, even when nerves are cut. However, rare nerve-injury patients develop prolonged and disabling chronic pain (neuralgia). When pain severity is disproportionate to severity of the inciting injury, physicians and insurers may suspect exaggeration and limit care or benefits, although the nature of the relationship between lesion-size and the development and persistence of neuralgia remains largely unknown. We compared cellular changes in the spinal dorsal-horn (the initial CNS pain-processing area) after partial or total tibial-nerve axotomies in male Sprague-Dawley rats to determine if these changes are proportional to the numbers of peripheral axons cut. Unoperated rats provided controls. Plantar hind-paw responses to touch, pin, and cold were quantitated bilaterally to identity hyperalgesic rats. We also compared data from nerve-injured rats with or without hyperalgesic responses to mechanical hind-paw stimulation to evaluate concordance between pain behaviors and dorsal-horn cellular changes. Hyperalgesia was no less prevalent or severe after partial than after total axotomy. L. spinal-cord sections from rats killed 7 days postoperatively were labeled for markers of primary afferents (substance P calcitonin gene-related peptide isolectin B4, gamma aminobutyric acid, and glial fibrillary acidic protein), then labeled cells were stereologically quantitated in somatotopically defined dorsal-horn regions. Total axotomy reduced markers of primary afferents more than partial axotomy. In contrast, GABA-immunoreactive profiles were similarly reduced after both lesions, and in rats with sensory loss versus hyperalgesia. Numbers of GFAP-immunoreactive astrocytes increased independently of lesion size and pain status. Small nerve injuries can thus have magnified and disproportionate effects on dorsal-horn neurons and glia, perhaps providing a biological correlate for the disproportionate pain of post-traumatic neuralgias (including complex regional pain syndrome-I) that follow seemingly minor nerve injuries. However, the presence of similar dorsal-horn changes in rats without pain behaviors suggests that not all transcellular responses to axotomy are pain-specific. (C) 2009 IBRO.

TI In Vitro Priming Recapitulates In Vivo HIV-1 Specific T Cell Responses,
Revealing Rapid Loss of Virus Reactive CD4(+) T Cells in Acute HIV-1
Infection
SO PLOS ONE
LA English
DT Article
AB Background: The requirements for priming of HIV-specific T cell responses initially seen in infected individuals remain to be defined. Activation of T cell responses in lymph nodes requires cell-cell contact between T cells and DCs, which can give concurrent activation of T cells and HIV transmission.
Methodology: The study aim was to establish whether DCs pulsed with HIV-1 could prime HIV-specific T cell responses and to characterize these responses. Both infectious and aldrithiol-2 inactivated noninfectious HIV-1 were compared to establish efficiencies in priming and the type of responses elicited.
Findings: Our findings show that both infectious and inactivated HIV-1 pulsed DCs can prime HIV-specific responses from naive T cells. Responses included several CD4(+) and CD8(+) T cell epitopes shown to be recognized in vivo by acutely and chronically infected individuals and some CD4(+) T cell epitopes not identified previously. Follow up studies of acute and recent HIV infected samples revealed that these latter epitopes are among the earliest recognized in vivo, but the responses are lost rapidly, presumably through activation-induced general CD4(+) T cell depletion which renders the newly activated HIV-specific CD4(+) T cells prime targets for elimination.
Conclusion: Our studies highlight the ability of DCs to efficiently prime naive T cells and induce a broad repertoire of HIV-specific responses and also provide valuable insights to the pathogenesis of HIV-1 infection in vivo.

AB Heat-shock protein 90 (Hsp90) acts as a molecular chaperone required for maintaining the conformational stability of client proteins regulating cell proliferation, survival, and apoptosis. Here we investigate the biologic significance of Hsp90 inhibition in multiple myeloma (MM) and other hematologic tumors using an orally available novel small molecule inhibitor SNX-2112, which exhibits unique activities relative to 17-allyamino-17-demethoxy-geldanamycin (17-AAG). SNX-2112 triggers growth inhibition and is more potent than 17-AAG against MM and other malignancies. It induces apoptosis via caspase-8, -9, -3, and poly (ADP-ribose) polymerase cleavage. SNX-2112 inhibits cytokine-inducedAkt and extracellular signal-related kinase (ERK) activation and also overcomes the growth advantages conferred by interleukin-6, insulin-like growth factor-1, and bone marrow stromal cells. Importantly, SNX-2112 inhibits tube formation by human umbilical vein endothelial cells via abrogation of eNOS/Akt pathway and markedly inhibits osteoclast formation via down-regulation of ERK/c-fos and PU.1. Finally, SNX-2112, delivered by its prodrug SNX-5422, inhibits MM cell growth and prolongs survival in a xenograft murine model. Our results indicate that blockade of Hsp90 by SNX-2112 not only inhibitsMMcell growth but also acts in the bone marrow microenvironment to block angiogenesis and osteoclastogenesis. Taken together, our data provide the framework for clinical studies of SNX-2112 to improve patient outcome in MM and other hematologic malignancies. (Blood. 2009; 113:846-855)

AB Background: The number of genome-wide association studies (GWAS) is growing rapidly leading to the discovery and replication of many new disease loci. Combining results from multiple GWAS datasets may potentially strengthen previous conclusions and suggest new disease loci, pathways or pleiotropic genes. However, no database or centralized resource currently exists that contains anywhere near the full scope of GWAS results.
Methods: We collected available results from 118 GWAS articles into a database of 56,411 significant SNP-phenotype associations and accompanying information, making this database freely available here. In doing so, we met and describe here a number of challenges to creating an open access database of GWAS results. Through preliminary analyses and characterization of available GWAS, we demonstrate the potential to gain new insights by querying a database across GWAS.
Results: Using a genomic bin-based density analysis to search for highly associated regions of the genome, positive control loci (e. g., MHC loci) were detected with high sensitivity. Likewise, an analysis of highly repeated SNPs across GWAS identified replicated loci (e. g., APOE, LPL). At the same time we identified novel, highly suggestive loci for a variety of traits that did not meet genome-wide significant thresholds in prior analyses, in some cases with strong support from the primary medical genetics literature (SLC16A7, CSMD1, OAS1), suggesting these genes merit further study. Additional adjustment for linkage disequilibrium within most regions with a high density of GWAS associations did not materially alter our findings. Having a centralized database with standardized gene annotation also allowed us to examine the representation of functional gene categories (gene ontologies) containing one or more associations among top GWAS results. Genes relating to cell adhesion functions were highly over-represented among significant associations (p < 4.6 x 10(-14)), a finding which was not perturbed by a sensitivity analysis.
Conclusion: We provide access to a full gene-annotated GWAS database which could be used for further querying, analyses or integration with other genomic information. We make a number of general observations. Of reported associated SNPs, 40% lie within the boundaries of a RefSeq gene and 68% are within 60 kb of one, indicating a bias toward gene-centricity in the findings. We found considerable heterogeneity in information available from GWAS suggesting the wider community could benefit from standardization and centralization of results reporting.

AB Background: Hepatitis C virus (HCV) is a leading cause of chronic liver disease, end-stage cirrhosis, and liver cancer, but little is known about the burden of disease caused by the virus. We summarised burden of disease data presently available for Europe, compared the data to current expert estimates, and identified areas in which better data are needed.
Methods: Literature and international health databases were systematically searched for HCV-specific burden of disease data, including incidence, prevalence, mortality, disability-adjusted life-years (DALYs), and liver transplantation. Data were collected for the WHO European region with emphasis on 22 countries. If HCV-specific data were unavailable, these were calculated via HCV-attributable fractions.
Results: HCV-specific burden of disease data for Europe are scarce. Incidence data provided by national surveillance are not fully comparable and need to be standardised. HCV prevalence data are often inconclusive. According to available data, an estimated 7.3-8.8 million people (1.1-1.3%) are infected in our 22 focus countries. HCV-specific mortality, DALY, and transplantation data are unavailable. Estimations via HCV-attributable fractions indicate that HCV caused more than 86000 deaths and 1.2 million DALYs in the WHO European region in 2002. Most of the DALYs (95%) were accumulated by patients in preventable disease stages. About one-quarter of the liver transplants performed in 25 European countries in 2004 were attributable to HCV.
Conclusion: Our results indicate that hepatitis C is a major health problem and highlight the importance of timely antiviral treatment. However, data on the burden of disease of hepatitis C in Europe are scarce, outdated or inconclusive, which indicates that hepatitis C is still a neglected disease in many countries. What is needed are public awareness, co-ordinated action plans, and better data. European physicians should be aware that many infections are still undetected, provide timely testing and antiviral treatment, and avoid iatrogenic transmission.

AB A vaginal microbicide should prevent pathogen transmission without disrupting tissue barriers to infection. Ideally, it would not need to be applied immediately before sexual intercourse, when compliance is a problem. Intravaginal administration of small interfering RNA (siRNA) lipoplexes targeting Herpes Simplex Virus Type 2 (HSV-2) genes protects mice from HSV-2. However, protection is short-lived, and the transfection lipid on its own unacceptably enhances transmission. Here, we show that cholesterol-conjugated (chol)-siRNAs without lipid silence gene expression in the vagina without causing inflammation or inducing interferons. A viral siRNA prevents transmission within a day of challenge, whereas an siRNA targeting the HSV-2 receptor nectin-1 protects for a week, but protection is delayed for a few days until the receptor is down-modulated. Combining siRNAs targeting a viral and host gene protects mice from HSV-2 for a week, irrespective of the time of challenge. Therefore, intravaginal siRNAs could provide sustained protection against viral transmission.

AB We report on the measurement of the radiation hardness of silicon photomultipliers (SiPMs) manufactured by Fondazione Bruno Kessler in Italy (1 and 6.2 mm(2)), Center of Perspective Technology and Apparatus in Russia (1 and 4.4 mm(2)), and Hamamatsu Corporation in Japan (1 mm(2)). The SiPMs were irradiated using a beam of 212 MeV protons at Massachusetts General Hospital, receiving fluences of up to 3 x 10(10) protons per cm(2) with the SiPMs at operating voltage. Leakage currents were read continuously during the irradiation. The delivery of the protons was paused periodically to record scope traces in response to calibrated light pulses to monitor the gains, photon detection efficiencies. and dark counts of the SiPMs. The leakage current and dark noise are found to increase with fluence. The leakage current is found to be proportional to the mean square deviation of the noise distribution, indicating the dark counts are due to increased random individual pixel activation, while SiPMs remain fully functional as photon detectors. The SiPMs are found to anneal at room temperature with a reduction in the leakage current by a factor of 2 in about 100 days. (c) 2008 Elsevier B.V. All rights reserved.

AB The existence of a coupling between changes in neuronal activity, cerebral blood flow and blood oxygenation is well known. The explicit relationship between these systems, however, is complex and remains a subject of intense research. Here, we use direct electrophysiological recordings to predict blood flow and oxygenation changes measured with optical methods during parametric stimulation applied to the somatosensory cortex in rat brain. Using a multimodal model of the cerebral functional unit, we estimate a neurovascular and a neuro-metabolic transfer function relating the experimentally measured neural responses with the inputs to a vascular model predicting hemodynamic and blood oxygenation changes. We show that our model can accurately predict experimentally measured parametric hemodynamic evoked responses by using a single linear transfer function relationship with a reduced number of state parameters to relate the level of neural activity to evoked cerebral blood flow and oxygen metabolism changes. At the same time, we characterize the metabolic and vascular neural response functions and interpret their physiological significance.

DECISION-ANALYSIS
AB Background: Variants in genes involved in warfarin metabolism and sensitivity affect individual warfarin requirements and the risk for bleeding. Testing for these variant alleles might allow more personalized dosing of warfarin during the induction phase. In 2007, the U. S. Food and Drug Administration changed the labeling for warfarin (Coumadin, Bristol-Myers Squibb, Princeton, New Jersey), suggesting that clinicians consider genetic testing before initiating therapy.
Objective: To examine the cost-effectiveness of genotype-guided dosing versus standard induction of warfarin therapy for patients with nonvalvular atrial fibrillation.
Design: Markov state transition decision model.
Data Sources: MEDLINE searches and bibliographies from relevant articles of literature published in English.
Target Population: Outpatients or inpatients requiring initiation of warfarin therapy. The base case was a man age 69 years with newly diagnosed nonvalvular atrial fibrillation and no contraindications to warfarin therapy.
Time Horizon: Lifetime.
Perspective: Societal.
Intervention: Genotype-guided dosing consisting of genotyping for CYP2C9*2, CYP2C9*3, and/or VKORC1 versus standard warfarin induction.
Outcome Measures: Effectiveness was measured in quality-adjusted life-years (QALYs), and costs were in 2007 U. S. dollars.
Results: In the base case, genotype-guided dosing resulted in better outcomes, but at a relatively high cost. Overall, the marginal cost-effectiveness of testing exceeded $170 000 per QALY. On the basis of current data and cost of testing (about $ 400), there is only a 10% chance that genotype-guided dosing is likely to be cost-effective (that is, <$50 000 per QALY). Sensitivity analyses revealed that for genetic testing to cost less than $ 50 000 per QALY, it would have to be restricted to patients at high risk for hemorrhage or meet the following optimistic criteria: prevent greater than 32% of major bleeding events, be available within 24 hours, and cost less than $200.
Limitation: Few published studies describe the effect of genotype-guided dosing on major bleeding events, and although these studies show a trend toward decreased bleeding, the results are not statistically significant.
Conclusion: Warfarin-related genotyping is unlikely to be cost-effective for typical patients with nonvalvular atrial fibrillation, but may be cost-effective in patients at high risk for hemorrhage who are starting warfarin therapy.

AB Bariatric surgery leads to substantial and durable weight reduction. Nearly 30% of patients who undergo bariatric surgery have type 2 diabetes, and for many of them, diabetes resolves after surgery (84% to 98% for bypass procedures and 48% to 68% for restrictive procedures). Glycemic control improves in part because of caloric restriction but also because gut peptide secretion changes. Gut peptides, which mediate the enteroinsular axis, include the incretins glucagon-like peptide-1 and glucose-dependent insulinotropic peptide, as well as ghrelin and peptide YY. Bariatric surgery (particularly bypass procedures) alters secretion of these gut hormones, which results in enhanced insulin secretion and sensitivity. This review discusses the various bariatric procedures and how they alter the enteroinsular axis. Familiarity with these effects can help physicians decide among the different surgical procedures and avoid postoperative hypoglycemia.

AB Background: Msx originated early in animal evolution and is implicated in human genetic disorders. To reconstruct the functional evolution of Msx and inform the study of human mutations, we analyzed the phylogeny and synteny of 46 metazoan Msx proteins and tracked the duplication, diversification and loss of conserved motifs.
Results: Vertebrate Msx sequences sort into distinct Msx1, Msx2 and Msx3 clades. The sister-group relationship between MSX1 and MSX2 reflects their derivation from the 4p/5q chromosomal paralogon, a derivative of the original "MetaHox" cluster. We demonstrate physical linkage between Msx and other MetaHox genes (Hmx, NK1, Emx) in a cnidarian. Seven conserved domains, including two Groucho repression domains (N- and C-terminal), were present in the ancestral Msx. In cnidarians, the Groucho domains are highly similar. In vertebrate Msx1, the N- terminal Groucho domain is conserved, while the C-terminal domain diverged substantially, implying a novel function. In vertebrate Msx2 and Msx3, the C-terminal domain was lost. MSX1 mutations associated with ectodermal dysplasia or orofacial clefting disorders map to conserved domains in a non-random fashion.
Conclusion: Msx originated from a MetaHox ancestor that also gave rise to Tlx, Demox, NK, and possibly EHGbox, Hox and ParaHox genes. Duplication, divergence or loss of domains played a central role in the functional evolution of Msx. Duplicated domains allow pleiotropically expressed proteins to evolve new functions without disrupting existing interaction networks. Human missense sequence variants reside within evolutionarily conserved domains, likely disrupting protein function. This phylogenomic evaluation of candidate disease markers will inform clinical and functional studies.

AB Background-Delirium is a common outcome after cardiac surgery. Delirium prediction rules identify patients at risk for delirium who may benefit from targeted prevention strategies, early identification, and treatment of underlying causes. The purpose of the present prospective study was to develop a prediction rule for delirium in a cardiac surgery cohort and to validate it in an independent cohort.
Methods and Results-Prospectively, cardiac surgery patients >= 60 years of age were enrolled in a derivation sample (n = 122) and then a validation sample (n = 109). Beginning on the second postoperative day, patients underwent a standardized daily delirium assessment, and delirium was diagnosed according to the confusion assessment method. Delirium occurred in 63 (52%) of the derivation cohort patients. Multivariable analysis identified 4 variables independently associated with delirium: prior stroke or transient ischemic attack, Mini Mental State Examination score, abnormal serum albumin, and the Geriatric Depression Scale. Points were assigned to each variable: Mini Mental State Examination <= 23 received 2 points, and Mini Mental State Examination score of 24 to 27 received 1 point; Geriatric Depression Scale >4, prior stroke/transient ischemic attack, and abnormal albumin received 1 point each. In the derivation sample, the cumulative incidence of delirium for point levels of 0, 1, 2, and >= 3 was 19%, 47%, 63%, and 86%, respectively (C statistic, 0.74). The corresponding incidence of delirium in the validation sample was 18%, 43%, 60%, and 87%, respectively (C statistic, 0.75).
Conclusions-Delirium occurs frequently after cardiac surgery. Using 4 preoperative characteristics, clinicians can determine cardiac surgery patients' risk for delirium. Patients at higher delirium risk could be candidates for close postoperative monitoring and interventions to prevent delirium. (Circulation. 2009;119:229-236.)

AB Background-The importance and therapeutic value of stem cells in lymphangiogenesis are poorly understood. We evaluated the potential of human and murine mesenchymal stem cells (MSCs) to acquire a lymphatic phenotype in vitro and to enhance lymphatic regeneration in vivo.
Methods and Results-We assessed the lymphendothelial differentiation of human and murine MSCs after induction with supernatant derived from human dermal microvascular endothelial cells, isolated lymphatic endothelial cells, and purified vascular endothelial growth factor (VEGF)-C in vitro. We used human or murine progenitor MSC lines and then characterized the lymphatic phenotype by morphology, migratory capacity, and the expression of lymphatic markers such as Prox-1, podoplanin, Lyve-1, VEGF receptor-2, and VEGF receptor-3. Using a murine lymphatic edema model, we assessed the potential of these cells to form a functional lymphatic vasculature in vivo after injection of syngeneic MSCs. Incubation with supernatant from lymphatic endothelial cells induced an endothelium-like morphology and the expression of lymphendothelial markers in both human and murine MSCs in vitro. MSCs showed migratory activity along a VEGF-C gradient, which was enhanced by VEGF-C conditioning. In vivo, the local application of MSCs resulted in a significant decrease in edema formation (-20.1%; P<0.01 versus untreated tails) after 3 weekly cell injections and restored the drainage of intradermally injected methylene blue after 7 weekly injections.
Conclusions-MSCs were capable of expressing a lymphatic phenotype when exposed to lymph-inductive media and purified VEGF-C. Migratory activity toward VEGF-C in vitro suggests homing capability in vivo. Restoration of lymphatic drainage after injection of MSCs in a lymphedema model indicates that MSCs play a role in lymphatic regeneration. The potential clinical application of MSC in wound healing and reduction of lymphatic edema warrants further research. (Circulation. 2009;119:281-289.)

AB Purpose
Atypical teratoid rhabdoid tumor (ATRT) of the CNS is a highly malignant neoplasm primarily affecting young children, with a historic median survival ranging from 6 to 11 months. Based on a previous pilot series, a prospective multi-institutional trial was conducted for patients with newly diagnosed CNS ATRT.
Patients and Methods
Treatment was divided into five phases: preirradiation, chemoradiation, consolidation, maintenance, and continuation therapy. Intrathecal chemotherapy was administered, alternating intralumbar and intraventricular routes. Radiation therapy (RT) was prescribed, either focal (54 Gy) or craniospinal (36 Gy, plus primary boost), depending on age and extent of disease at diagnosis.
Results
Between 2004 and 2006, 25 patients were enrolled; 20 were eligible for evaluation. Median age at diagnosis was 26 months (range, 2.4 months to 19.5 years). Gross total resection of the primary tumor was achieved in 11 patients. Fourteen patients had M0 disease at diagnosis, one patient had M2 disease, and five patients had M3 disease. Fifteen patients received radiation therapy: 11 focal and four craniospinal. Significant toxicities, in addition to the expected, included radiation recall (n = 2) and transverse myelitis (n = 1). There was one toxic death. Of the 12 patients who were assessable for chemotherapeutic response (pre-RT), the objective response rate was 58%. The objective response rate observed after RT was 38%. The 2-year progression-free and overall survival rates are 53% +/- 13% and 70% +/- 10%, respectively. Median overall survival has not yet been reached.
Conclusion
This intensive multimodality regimen has resulted in a significant improvement in time to progression and overall survival for patients with this previously poor-prognosis tumor.

AB Background: Amyloid-beta protein (A beta) plays a key role in Alzheimer disease (AD) and is also implicated in cerebral small vessel disease. Serum total homocysteine (tHcy) is a risk factor for small vessel disease and cognitive impairment and correlates with plasma A beta levels. To determine whether this association results from a common pathophysiologic mechanism, we investigated whether vitamin supplementation-induced reduction of tHcy influences plasma A beta levels in the Vitamin Intervention in Stroke Prevention (VISP) study.
Methods: Two groups of 150 patients treated with either the high-dose or low-dose formulation of pyridoxine, cobalamin, and folic acid in a randomized, double-blind fashion were selected among the participants in the VISP study without recurrent stroke during follow-up and in the highest 10% of the distribution for baseline tHcy levels. Concentrations of plasma A beta with 40 (A beta 40) and 42 (A beta 42) amino acids were measured at baseline and at the 2-year visit.
Results: tHcy levels significantly decreased with vitamin supplementation in both groups. tHcy were strongly correlated with A beta 40 but not A beta 42 concentrations. There was no difference in the change in A beta 40, A beta 42 (p = 0.40, p = 0.35), or the A beta 42/A beta 40 ratio over time (p = 0.86) between treatment groups. A beta measures were not associated with cognitive change.
Conclusions: This double-blind randomized controlled trial of vitamin therapy demonstrates a strong correlation between serum tHcy and plasma A beta 40 concentrations in subjects with ischemic stroke. Treatment with high dose vitamins does not, however, influence plasma levels of A beta, despite their effect on lowering tHcy. Our results suggest that although tHcy is associated with plasma A beta 40, they may be regulated by independent mechanisms. Neurology (R) 2009;72:268-272

AB The CDC73 tumor suppressor gene is mutationally inactivated in hereditary and sporadic parathyroid tumors. Its product, the Cdc73 protein, is a component of the RNA polymerase II and chromatin-associated human Paf1 complex (Paf1C). Here, we show that Cdc73 physically associates with the cleavage and polyadenylation specificity factor (CPSF) and cleavage stimulation factor (CstF) complexes that are required for the maturation of mRNA 3' ends in the cell nucleus. Immunodepletion experiments indicate that the Cdc73-CPSF-CstF complex is necessary for 3' mRNA processing in vitro. Microarray analysis of CDC73 siRNA-treated cells revealed INTS6, a gene encoding a subunit of the Integrator complex, as an in vivo Cdc73 target. Cdc73 depletion by siRNA resulted in decreased INTS6 mRNA abundance, and decreased association of CPSF and CstF subunits with the INTS6 locus. Our results suggest that Cdc73 facilitates association of 3' mRNA processing factors with actively-transcribed chromatin and support the importance of links between tumor suppression and mRNA maturation.

AB Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the brain caused by JC virus (JCV) for which there is no cure. PML patients who have JCV-specific CD8(+) cytotoxic T lymphocytes (CTL) in their blood have a better clinical outcome. We compared JCV-specific CTL responses in vitro elicited either by JCV peptide-loaded dendritic cells (DC) or by direct peptide stimulation of lymphocytes from 20 HLA-A*0201(+) healthy controls, HIV+ and PML patients. JCV peptide-loaded DC elicited a stronger CTL expansion in 13/15 responders. DC can induce a potent JCV-specific CTL response in vitro, and may constitute a promising approach for PML immunotherapy.

AB The muscle ubiquitin ligases MAFbx and MuRF1 are upregulated in and promote muscle atrophy. Upregulation of MAFbx and MuRF1 by glucocorticoids has been linked to activation of FOXO1 and FOXO3A resulting from reduced Akt activity. We determined the requirements for the glucocorticoid receptor (GR) in these biological responses in C2C12 cells in which GR expression was knocked down by stable expression of an shRNA. Loss of GR prevented dexamethasone-induced increases in protein catabolism. Loss of GR. or inhibition of ligand binding to GR with RU486, prevented upregulation of MAFbx and MuRF1 by dexamethasone. Loss of GR also prevented dexamethasone-induced decreases in Akt phosphorylation, and increases in the fraction of FOXO1 that was unphosphorylated. The findings establish a requirement for the GR in activating molecular signals that promote muscle protein catabolism. Published by Elsevier Inc.

AB Foxp3(+) regulatory T (Treg) cells limit pathogenic immune responses to self-antigens and foreign antigens. An essential role for microRNA (miRNA) in the maintenance and function of Treg cells, revealed by the Treg cell-specific Dicer ablation, raised a question as to a specific miRNA contribution. We found that Foxp3 controlled the elevated miR155 expression required for maintaining Treg cell proliferative activity and numbers under nonlymphopenic conditions. Moreover, miR155 deficiency in Treg cells resulted in increased suppressor of cytokine signaling 1 (SOCS1) expression accompanied by impaired activation of signal transducer and activator of transcription 5 (STAT5) transcription factor in response to limiting amounts of interleukin-2. Our studies suggest that Foxp3-dependent regulation of miR155 maintains competitive fitness of Treg cells by targeting SOCS1, and they provide experimental support for a proposed role for miRNAs in ensuring the robustness of cellular phenotypes.

AB Helicobacter pylori VacA toxin contributes to the pathogenesis and severity of gastric injury. We found that incubation of AZ-521 cells with VacA resulted in phosphorylation of protein kinase B (Akt) and glycogen synthase kinase-3 beta (GSK3 beta) through a PI3K-dependent pathway. Following phosphorylation and inhibition of GSK3 beta,beta-catenin was released from a GSK3 beta/beta-catenin complex, with subsequent nuclear translocation. Methyl-beta-cyclodextrin (MCD) and phosphatidylinositol-specific phospholipase C (PIPLC), but not 5-nitro-2-(3-phenylpropylamino)-benzoic acid (NPPB) and bafilomycin A1, inhibited VacA-induced phosphorylation of Akt, indicating that it does not require VacA internalization and is independent of vacuolation. VacA treatment of AZ-521 cells transfected with TOPtkLuciferase reporter plasmid or control FOPtkLucifease reporter plasmid resulted in activation of TOPtkLuciferase, but not FOPtkLucifease. In addition, VacA transactivated the beta-catenin-dependent cyclin D1 promoter in a luciferase reporter assay. Infection of AZ-521 cells by a vacA mutant strain of H. pylori failed to induce phosphorylation of Akt and GSK3 beta, or release of beta-catenin from a GSK3 beta/beta-catenin complex. Taken together, these results support the conclusion that VacA activates the PI3K/Akt signaling pathway, resulting in phosphorylation and inhibition of GSK3 beta, and subsequent translocation of beta-catenin to the nucleus, consistent with effects of VacA on beta-catenin-regulated transcriptional activity. These data introduce the possibility that Wnt-dependent signaling might play a role in the pathogenesis of H. pylori infection, including the development of gastric cancer.

AB Activation of naive CD8(+) T cells with antigen induces their differentiation into effector cytolytic T lymphocytes (CTLs). CTLs lyse infected or aberrant target cells by exocytosis of lytic granules containing the pore-forming protein perforin and a family of proteases termed granzymes. We show that effector CTL differentiation occurs in two sequential phases in vitro, characterized by early induction of T-bet and late induction of Eomesodermin (Eomes), T-box transcription factors that regulate the early and late phases of interferon (IFN) gamma expression, respectively. In addition, we demonstrate a critical role for the transcription factor Runx3 in CTL differentiation. Runx3 regulates Eomes expression as well as expression of three cardinal markers of the effector CTL program: IFN-gamma, perforin, and granzyme B. Our data point to the existence of an elaborate transcriptional network in which Runx3 initially induces and then cooperates with T-box transcription factors to regulate gene transcription in differentiating CTLs.

AB We show that the enzymatic acetylation and deacetylation of a cell surface carbohydrate controls B cell development, signaling, and immunological tolerance. Mice with a mutation in sialate:O-acetyl esterase, an enzyme that specifically removes acetyl moieties from the 9-OH position of alpha 2-6-linked sialic acid, exhibit enhanced B cell receptor (BCR) activation, defects in peripheral B cell development, and spontaneously develop antichromatin autoantibodies and glomerular immune complex deposits. The 9-O-acetylation state of sialic acid regulates the function of CD22, a Siglec that functions in vivo as an inhibitor of BCR signaling. These results describe a novel catalytic regulator of B cell signaling and underscore the crucial role of inhibitory signaling in the maintenance of immunological tolerance in the B lineage.

AB To establish effective therapeutic strategies for eosinophil-related disorders, it is critical to understand the developmental pathway of human eosinophils. In mouse hematopoiesis, eosinophils originate from the eosinophil lineage-committed progenitor (EoP) that has been purified downstream of the granulocyte/macrophage progenitor (GMP). We show that the EoP is also isolatable in human adult bone marrow. The previously defined human common myeloid progenitor (hCMP) population (Manz, M. G., T. Miyamoto, K. Akashi, and I.L. Weissman. 2002. Proc. Natl. Acad. Sci. USA. 99: 11872-11877) was composed of the interleukin 5 receptor alpha chain(+) (IL-5R alpha(+)) and IL-5R alpha(-) fractions, and the former was the hEoP. The IL5R alpha(+)CD34(+)CD38(+)IL-3R alpha(+)CD45RA(-) hEoPs gave rise exclusively to pure eosinophil colonies but never differentiated into basophils or neutrophils. The IL-5R alpha(-) hCMP generated the hEoP together with the hGMP or the human megakaryocyte/erythrocyte progenitor (hMEP), whereas hGMPs or hMEPs never differentiated into eosinophils. Importantly, the number of hEoPs increased up to 20% of the conventional hCMP population in the bone marrow of patients with eosinophilia, suggesting that the hEoP stage is involved in eosinophil differentiation and expansion in vivo. Accordingly, the phenotypic definition of hCMP should be revised to exclude the hEoP; an "IL-5R alpha-negative" criterion should be added to define more homogenous hCMP. The newly identified hEoP is a powerful tool in studying pathogenesis of eosinophilia and could be a therapeutic target for a variety of eosinophil-related disorders.

AB Microglia are resident immune cells of brain and activated by peripheral tissue injury. In the present study, we investigated the possible induction of several microglial surface immunomolecules in the spinal cord, including leukocyte common antigen (LCA/CD45), MHC class I antigen, MHC class II antigen, Fc receptor, and CD11c following formalin injection into the rat's hind paw. CD45 and MHC class I were upregulated in the activated microglia, which was evident on day 3 with the peak expression on day 7 following peripheral formalin injection. There was a very low basal expression of MHC class II, CD11c, and the Fc receptor, which did not change after the formalin injection. These results, for the first time, indicate that peripheral formalin injection can induce phenotypic changes of microglia with distinct upregulation of CD45 and MHC class I antigen. The data suggest that phenotypic changes of the activated microglia may be a unique pattern of central changes following peripheral tissue injury. (c) 2008 Elsevier Ireland Ltd. All rights reserved.

AB A significant proportion of patients with myocardial infarction are missed upon initial presentation to the emergency department. The 12-lead electrocardiogram (ECG) has a low sensitivity for the detection of acute myocardial infarction, especially if the culprit lesion is in the left circumflex artery (LCA). This study was designed to evaluate the benefit of adding 3 posterior chest leads on top of the 12-lead ECG to detect ischemia resulting from LC disease, using a model of temporary balloon occlusion to produce ischemia. We studied 53 consecutive patients who underwent clinically indicated coronary interventions. At the time of coronary angiography, the balloon was inflated to produce complete occlusion of the proximal LCA. We recorded and analyzed the changes noted on the 15-lead ECG, which included 3 posterior leads in addition to the standard 12 leads. In response to acute occlusion of the LCA, the posterior chest leads showed more ST elevation than the other leads, and more patients had ST elevation in the posterior leads than in any other lead. The 15-lead ECG was able to detect >= 0.5 mm (74% vs 38%, p<0.0001) and >= 1 mm (62% vs 34%, p<0.0001) ST elevation in any 2 contiguous leads more frequently than the 12-lead ECG. In conclusion, the 15-lead ECG identified more patients with posterior myocardial wall ischemia because of temporary balloon occlusion of the LC than the 12-lead ECG. This information may enhance the detection of posterior MI in the emergency department and potentially facilitate early institution of reperfusion therapy. (C) 2009 Elsevier Inc.

SO AMERICAN JOURNAL OF CARDIOLOGY

ID RHYTHM CONTROL; RISK-FACTORS; THERAPY; CARE
AB Anticoagulation therapy significantly reduces the incidence of thromboembolic events in patients with atrial fibrillation (AF), and warfarin therapy at discharge is a class I-indicated drug in patients with ischemic stroke with persistent or paroxysmal AF without contraindications. The aim was to determine whether participation in the Get With The Guidelines-Stroke (GWTG-S) quality improvement program would be associated with improved adherence to anticoagulation guidelines for patients with all types of AF. Adherence to warfarin treatment at hospital discharge was assessed in eligible patients with AF who presented with stroke or transient ischemic attack, based on type of AF. Of patients with stroke, 10.5% presented with some form of AF. When AF was documented using electrocardiography or telemetry (ECG) during the present admission, eligible patients were more likely to receive warfarin compared with patients for whom AF was reported using medical history only (78.8% vs 49.4%; p<0.0001). Improvement after GWTG-S participation in warfarin use was observed in patients with ECG-documented AF (73.8% at baseline vs 88.5% after the intervention; p<0.0001), but not patients using history only. Women and elderly patients were less likely to receive warfarin, and these gaps in treatment did not narrow during the quality improvement program for patients with ECG-documented AF and those with history only. In conclusion, anticoagulation for stroke prevention was underused in general for patients with AF, even in such high-risk groups as patients with stroke. GWTG-S was associated with improved adherence for patients with ECG-documented AF, but patients with a history of AF alone were largely untreated. (C) 2009 Elsevier Inc.

AB The human embryonic kidney (HEK) 293 cell line is widely used in cell biology research. Although HEK293 cells have been meticulously studied, our knowledge about endogenous G protein-coupled receptors (GPCR) in these cells is incomplete. While studying the effects of bradykinin (BK), a potent growth factor for renal cells, we unexpectedly discovered that BK activates extracellular signal-regulated protein kinase 1 and 2 (ERK) in HEK293 cells. Thus, we hypothesized that HEK293 cells possess endogenous BK receptors. RT-PCR demonstrated the presence of mRNAs for BK B-1 and BK B-2 receptors in HEK293 cells. Western blotting with BK B-1 and BK B-2 receptor antibodies confirmed this result at the protein level. To establish that BK receptors are functional, we employed fluorescent measurements of intracellular Ca2+, measured changes in extracellular acidification rate (ECAR) as a reflection of the Na+/H+ exchange (NHE) with a Cytosensor (TM) microphysiometer, and assessed ERK activation by Western blotting with a phospho-specific ERK antibody. Exposure of HEK293 cells to BK produced a concentration-dependent rise in intracellular Ca2+, (EC50 = 36.5 +/- 8.0 x 10 (9) M), a rapid increase in tyrosine phosphorylation of ERK (EC50 = 9.8 +/- 0.4 x 10 (9) M), and elevation in ECAR by similar to 20%. All of these signals were blocked by HOE-140 (B-2 receptor antagonist) but not by des-Arg(10)-HOE-140 (B-1 receptor antagonist). We conclude that HEK293 cells express endogenous functional BK B-2 receptors, which couple to the mobilization of intracellular Ca2+, increases in ECAR and increases in ERK phosphorylation.

AB Background: The mammalian forkhead box, class O (FoxO) transcription factors function to regulate diverse physiological processes. Emerging evidence that both brain-derived neurotrophic factor (BDNF) and lithium suppress FoxO activity suggests a potential role of FoxOs in regulating mood-relevant behavior. Here, we investigated whether brain FoxO1 and FoxO3a can be regulated by serotonin and antidepressant treatment and whether their genetic deletion affects behaviors.
Methods: C57BL/6 mice were treated with D-fenfluramine to increase brain serotonergic activity or with the antidepressant imipramine. The functional status of brain FoxO1 and FoxO3a was audited by immunoblot analysis for phosphorylation and subcellular localization. The behavioral manifestations in FoxO1- and FoxO3a-deficient mice were assessed via the Elevated Plus Maze Test, Forced Swim Test, Tail Suspension Test, and Open Field Test.
Results: Increasing serotonergic activity by D-fenfluramine strongly increased phosphorylation of FoxO1 and FoxO3a in several brain regions and reduced nuclear FoxO1 and FoxO3a. The effect Of D-fenfluramine was mediated by the phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway. Chronic, but not acute, treatment with the antidepressant imipramine also increased the phosphorylation of brain FoxO1 and FoxO3a. When FoxO1 was selectively deleted from brain, mice displayed reduced anxiety. In contrast, FoxO3a-deficient mice presented with a significant antidepressant-like behavior.
Conclusions: FoxOs may be a transcriptional target for anxiety and mood disorder treatment. Despite their physical and functional relatedness, FoxO1 and FoxO3a influence distinct behavioral processes linked to anxiety and depression. Findings in this study reveal important new roles of FoxOs in brain and provide a molecular framework for further investigation of how FoxOs may govern mood and anxiety disorders.

AB Waldenstrom macroglobulinemia (WM) is an incurable low-grade lymphoma characterized by bone marrow (BM) involvement of IgM secreting lymphoplasmacytic cells. The induction of unfolded protein response (UPR) genes ("physiologic" UPR) enables cells to differentiate into professional secretory cells capable of production of high amounts of endoplasmic reticulum (ER)-processed proteins, such as immunoglobulins. Ultimately, the initially cytoprotective UPR triggers an apoptotic cascade if ER stress is not corrected, called proapoptotic/terminal UPR. We show that WM cells inherently express the physiologic UPR machinery compared with normal BM cells, and that increased ER stress leads to proapoptotic/terminal UPR in WM cells. We therefore examined tunicamycin, ER stress inducer, for potential antitumor effects in WM. Tunicamycin induced significant cytotoxicity, apoptosis and cell-cycle arrest, and inhibited DNA synthesis in WM cell lines and primary BM CD19(+) cells from patients with WM with an inhibitory concentration (IC(50)) of 0.5 mu g/mL to 1 mu g/mL, but not in healthy donor cells. Importantly, coculture of WM cells in the context of the BM microenvironment did not inhibit tunicamycin-induced cytotoxicity. Finally, we demonstrate that ER stress inducer synergizes with other agents used in the treatment of WM. These preclinical studies provide a framework for further evaluation of ER stress inducing agents as therapeutic agents in WM. (Blood. 2009; 113: 626-634)

AB The intracellular Ca(2+) concentration of many nonexcitable cells is regulated by calcium store release and store-operated calcium entry (SOCE). In platelets, STIM1 was recently identified as the main calcium sensor expressed in the endoplasmic reticulum. To evaluate the role of the SOC channel moiety, Orai1, in platelet SOCE, we generated mice expressing a mutated, inactive form of Orai1 in blood cells only (Orai1(R93W)). Platelets expressing Orai1R93W were characterized by markedly reduced SOCE and impaired agonist-induced increases in [Ca(2+)](i). Orai1(R93W) platelets showed reduced integrin activation and impaired degranulation when stimulated with low agonist concentrations under static conditions. This defect, however, did not significantly affect the ability of Orai1(R93W) platelets to aggregate or to adhere to collagen under arterial flow conditions ex vivo. In contrast, these adherent Orai1(R93W) platelets were defective in surface phosphatidylserine exposure, suggesting that Orai1 is crucial for the platelets' procoagulant response rather than for other Ca(2+)- dependent cellular responses.

AB BACKGROUND: Clinicians observe that advanced cancer patients with dependent children agonize over the impact their death will have on their children. The objective of this study was to determine empirically whether advanced cancer patients with and without dependent children differ in treatment preferences, mental health, and end-of-life (EOL) outcomes. METHODS: Coping with Cancer is a National Cancer Institute/National Institute of Mental Health-funded, multi-institutional, prospective cohort study of 668 patients with advanced cancer. Patients with and without dependent children were compared on rates of psychiatric disorders, advance care planning (ACID), EOL care, quality of their last week of life, and location of death. RESULTS: In adjusted analyses, patients with advanced cancer who had dependent children were more likely to meet panic disorder criteria (adjusted odds ratio [AOR], 5.41; 95% confidence interval [95% CI], 2,13-13.69), more likely to be worried (mean difference in standard deviations [delta], 0.09; P = .006), and more likely to prefer aggressive treatment over palliative care (AOR, 1.77; 95% Cl, 1.07-2.93). Patients with dependent children were less likely to engage in ACID (eg, do not resuscitate orders: AOR, 0.44; 95% Cl, 0.26-0.75) and had a worse quality of life in the last week of life (delta, 0.15; P - .007). Among spousal care-givers, those with dependent children were more likely to meet criteria for major depressive disorder (AOR, 4.53: 95% Cl, 1.47-14) and generalized anxiety disorder (AOR, 3.95; 95% Cl, 1.29-12.16). CONCLUSIONS: Patients with dependent children were more anxious, were less likely to engage in ACID, and were more likely to have a worse quality of life in their last week of life. Advanced cancer patients and spousal caregivers with dependent children represent a particularly distressed group that warrants further clinical attention, research, and support.

AB During cell proliferation, DNA damage inflicted by intrinsic or extrinsic genotoxic stresses impose a thereat to DNA replication. The stability of the DNA replication forks that encounter DNA damage is crucial for genomic integrity. Both the ATR-regulated checkpoint pathway and the translesion DNA synthesis mediated by the ubiquitinated PCNA are important for continuous replication of damaged DNA. We have recently shown that Chk1, a key effector kinase of ATR in checkpoint response, is required for efficient PCNA ubiquitination after DNA damage. Surprisingly, the ubiquitination of PCNA is independent of ATR, but regulated by Claspin, a replication protein that mediates the activation of Chk1 by ATR. Like Claspin, Timeless and Rad17, two other Chk1 regulators at stressed replication forks, are also implicated in PCNA ubiquitination. These findings suggest that while ATR signaling and PCNA ubiquitination are two independent processes, they are mediated by a common group of proteins including Chk1 and it regulators at replication forks. Furthermore, these data raise the possibility that Chk1 and its regulators may constitute a functional module at replication forks to enable multiple stress responses.

AB The mammalian NIMA-related protein kinase 1 (Nek1) is important for keeping cells alive after DNA damage, but the mechanism by which injured cells die without functional Nek1 has not yet been demonstrated. Here we show that Nek1 regulates the pathway to mitochondrial cell death through phosphorylation of voltage dependent anion channel 1 (VDAC1) on serine 193. Nek1 associates with VDAC1 in a yeast two-hybrid system, as well as by GST pull-down assays and by reciprocal immunoprecipitation. A portion of Nek1 in cells also localizes at mitochondria. Ectopic expression of a kinase-dead Nek1 mutant results in cell death, which is immediately preceded by loss of the Nek1-dependent VDAC1-S193 phosphorylation. UV irradiation of Nek1-deficient cells or silencing of endogenous Nek1 expression similarly results in loss of the specific S193 phosphorylation before cells die. Nek1-deficient cells are characterized by exaggerated mitochondrial membrane permeability (MMP) and accelerated cell death. Ectopic expression of a VDAC1-Ser193Ala mutant, which cannot be phosphorylated by Nek1, also results in cell death. A VDAC1-Ser193Glu mutant, designed to mimic constitutive phosphorylation by Nek1, rescues exaggerated MMP and keeps cells alive after DNA damaging injury, but only transiently. The direct interaction between Nek1 and VDAC1 provides a mechanism to explain how Nek1 prevents excessive cell death, as well as the first direct evidence that a specific kinase regulates VDAC1 activity.

AB Purpose: Poly (ADP-ribose) polymerase (PARP) inhibitors are undergoing clinical evaluation for cancer therapy, Because PARP inhibition has been shown to enhance tumor cell sensitivity to radiation, we investigated the in vitro and in vivo effects of the novel PARP inhibitor E7016.
Experimental Design: The effect of E7016 on the in vitro radiosensitivity of tumor cell lines was evaluated using clonogenic survival. DNA damage and repair were measured using gamma H2AX foci and neutral comet assay. Mitotic catastrophe was determined by immunostaining. Tumor growth delay was evaluated in mice for the effect of E7016 on in vivo (U251) tumor radiosensitivity.
Results: Cell lines exposed to E7016 preirradiation yielded an increase in radiosensitivity with dose enhancement factors at a surviving fraction of 0.1 from 1.4 to 1.7. To assess DNA double-strand breaks repair, gamma H2AX measured at 24 hours postirradiation had significantly more foci per cell in the E7016/irradiation group versus irradiation alone. Neutral comet assay further suggested unrepaired double-strand breaks with significantly greater DNA damage at 6 hours postirradiation in the combination group versus irradiation alone. Mitotic catastrophe staining revealed a significantly greater number of cells staining positive at 24 hours postirradiation in the combination group. In vivo, mice treated with E7016/irradiation/temozolomide had an additional growth delay of six days compared with the combination of temozolomide and irradiation.
Conclusions: These results indicate that E7016 can enhance tumor cell radiosensitivity in vitro and in vivo through the inhibition of DNA repair. Moreover, enhanced growth delay with the addition of E7016 to temozolomide and radiotherapy in a glioma mouse model suggests a potential role for this drug in the treatment of glioblastoma multiforme.

AB Purpose: Clinical observations have suggested that shedding of the MHC class I chain - related molecule (MIC) may be one of the mechanisms by which tumors evade host immunosurveillance and progress. However, this hypothesis has never been proven. In this study, we tested this hypothesis using a prostate tumor model and investigated the effect of shedding of MIC on tumor development.
Experimental Design: We generated a shedding-resistant noncleavable form of MICB (MICB.A2). We overexpressed MICB.A2, the wild-type MICB, and the recombinant soluble MICB (rsMICB) in mouse prostate tumor TRAMP-C2 (TC2) cells and implanted these cells into severe combined immunodeficient mice.
Results: No tumors were developed in animals that were implanted with TC2-MICB.A2 cells, whereas all the animals that were implanted with TC2, TC2-MICB, or TC2-rsMICB cells developed tumors. When a NKG2D-specific antibody CX5 or purified rsMICB was administered to animals before tumor implantation, all animals that were implanted with TC2-MICB.A2 cells developed tumors. In vitro cytotoxicity assay revealed the loss of NKG2D-mediated natural killer cell function in these prechallenged animals, suggesting that persistent levels of soluble MICB in the serum can impair natural killer cell function and thus allow tumor growth.
Conclusions: These data suggest that MIC shedding may contribute significantly to tumor formation by transformed cells and that inhibition of MIC shedding to sustain the NKG2D receptor-MIC ligand recognition may have potential clinical implication in targeted cancer treatment.

AB Background. Suboptimal drug exposure attributable to physician-directed dosage reductions of pegylated interferon and/or ribavirin are associated with decreased sustained virologic response rates. However, data are limited with regard to suboptimal drug exposure that is attributable to missed doses by patients with chronic hepatitis C virus (HCV) infection. We examined the relationship between adherence to pegylated interferon and ribavirin therapy, measured by pharmacy refill, and HCV suppression during the initial 12 weeks of therapy.
Methods. We conducted a cohort study involving 188 patients with chronic HCV infection who were treated with pegylated interferon plus ribavirin. Adherence was calculated using pharmacy refill data and could exceed 100%. The primary outcome was decrease in HCV load at 12 weeks; early virologic response was a secondary outcome. Mixed-effects regression models estimated the association between adherence and HCV suppression during the initial 12 weeks. Subanalyses were performed among patients who received optimal weight-based dosages.
Results. The mean decrease in HCV load at 12 weeks was 0.66 log IU/mL greater for patients with >= 85% adherence than for those with < 85% adherence (3.23 vs. 2.57 log IU/mL;). When patients who received Pp. 04 a suboptimal ribavirin dosage were excluded, the decrease in viral load was 1.00 log IU/mL greater for persons with >= 85% adherence (3.32 vs. 2.32 log IU/mL;). Early virologic response was more common among Pp. 01 patients with >= 85% adherence than it was among those with < 85% adherence to treatment with pegylated interferon (73% vs. 29%; P=.02) and ribavirin (73% vs. 55%; P=.08
Conclusions. Adherence of >= 85% to pegylated interferon and ribavirin treatment was associated with increased HCV suppression. Decreases in HCV load became greater when patients with >= 85% adherence to their regimen continued to receive their recommended weight-based ribavirin dosage.

AB Background. During acute human immunodeficiency virus (HIV) infection, high viral loads and the induction of host immune responses typically coincide with the onset of clinical symptoms. However, clinically severe presentations during acute HIV type 1 (HIV-1) infection, including AIDS-defining symptoms, are unusual.
Methods. Virus isolates were tested for clade, drug susceptibility, coreceptor use, and growth rate in 2 case reports of sexual transmission of HIV-1 infection. Human leukocyte antigen (HLA) genotype was determined, and HIV-1-specific cytotoxic T lymphocyte responses to an overlapping peptide set spanning the entire HIV clade A and clade B proteome were assayed.
Results. The viruses isolated in the 2 unrelated case reports of severe primary HIV-1 infection showed R5/X4 dual-mixed tropism, belonged to clade B and CRF02-AG, and were highly replicative in peripheral blood mononuclear cell culture. Impaired humoral responses were paralleled by a profound absence of HIV-1-specific cytotoxic T lymphocyte responses to the entire viral proteome in the 2 case reports. In 1 case report for which the virus source was available, there was a remarkable HLA similarity between the 2 patients involved in the transmission event, because 3 of 4 HLA-A and HLA-B alleles had matched HLA supertype for both patients.
Conclusions. The data suggest that concurrence of viral and host factors contributes to the clinical severity of primary HIV-1 infection and that patients infected with highly replicative, dual-tropic viruses are more prone to develop AIDS-defining symptoms during acute infection if they are unable to mount humoral and cellular HIV-1-specific immune responses. The presence of concordant HLA supertypes might facilitate the preferential transmission of HLA-adapted viral variants, further accelerating disease progression.

AB In vertebrates, the Mullerian duct elongates along the Wolffian duct, a mesonephric structure that is required for Mullerian duct formation. Recently, several genes required for initial Mullerian duct formation have been identified. However, the precise mechanism of Mullerian duct elongation remains to be elucidated. In this Study, we investigated dynamic morphological changes in the elongating Mullerian duct in rat urogenital ridges in organ culture manipulated by microincision and/or chemical inhibitors. Mechanical division of the developing Mullerian duct showed that epithelial cells of the Mullerian duct actively migrate along the anterior-posterior axis independent of the proliferative expansion of the anterior portion of the duct. We found that the PI3K/AKT signaling pathway is activated in the Mullerian duct epithelium and is required for elongation of the tip of the duct; however, migration of Mullerian duct epithelial cells proximal to the tip remains intact when PI3K/AKT is inactivated. Although much is known about the molecular and cellular mechanisms leading to Mullerian duct regression, the present findings provide a fuller understanding of the mechanisms contributing to Mullerian duct fort-nation and to the general process of early tubulogenesis.

AB To study evolution of dinucleotide simple sequence repeats (diSSRs) we searched recently available mammalian genomes for UTR-localized diSSRs with conserved upstream flanking sequences (CFS). There were 252 reported Homo sapiens genes containing the repeats (AC)n, (GT)n, (AG)n or (CT)n in their UTRs including 22 (8.7%) with diSSR-upstream flanking sequences conserved comparing divergent mammalian lineages represented by Homo sapiens and the marsupial, Monodelphis domestica. Of these 22 genes, 19 had known functions including 18 (95%) that proved critical for mammalian nervous systems (Fishers exact test, P<0.0001). The remaining gene, Cd2ap, proved critical for development of kidney podocytes, cells that have multiple similarities to neurons. Gene functions included voltage and chloride channels, synapse-associated proteins, neurotransmitter receptors, axon and dendrite pathfinders, a NeuroD potentiator and other neuronal activities. Repeat length polymorphism was confirmed for 68% of CFS diSSRs even though these repeats were nestled among highly conserved sequences. This finding supports a hypothesis that SSR polymorphism has functional implications. A parallel study was performed on the self-complementary diSSRs (AT)n and (GC)n. When flanked by conserved sequences, the self-complementary diSSR (AT)n was also associated with genes expressed in the developing nervous system. Our findings implicate functional roles for diSSRs in nervous system development. Published by Elsevier B.V.

AB New genome sequence information was used to study evolution of 22 dinucleotide simple sequence repeat (diSSR) sites whose upstream flanking sequences were shown to be conserved comparing Homo sapiens with the marsupial, Monodelphis domestica. Among mammals, most of these diSSR sites were conserved both upstream and downstream of the diSSR. However, individual diSSRs were frequently replaced by alternative repeats. Conserved among mammals examined, the Vsnl1 gene's 3' UTR-localized (AC)n repeat replaced an A-rich tract in non-mammalian vertebrates examined. The Sema6D gene's (GT)n was also well conserved among mammals examined. Such conservation provides evidence of a functional role. The UTR-localized diSSRs of other genes evolved by replacing alternative diSSRs, by replacing mononucleotide-rich tracts and, in fewer cases, by expansion from short repeating sequences. Extension of the study to less conserved diSSR sites revealed that some diSSRs replaced post-transcriptional regulatory motifs, such as AU-rich elements (AREs) and C-rich tracts. The Mtap2 gene's UTR-localized (AC)n was located within a known dendritic targeting element. These evolutionary replacements suggest that some diSSRs belong to a broader group of weak-folding repetitive sequences with potential regulatory roles. Published by Elsevier B.V.

AB Cadherins and the immunoglobulin (Ig) proteins give rise to a multitude of surface receptors, which function as diverse cell adhesion molecules (CAMs) or signal-transducing receptors. These functions are often interdependent, and rely on a high degree of specificity in homophilic binding as well as heterophilic interactions. The Drosophila receptor Dscam is an exceptional example of homophilic binding specificity involved in a number of important biological processes, such as neural wiring and innate immunity. Combinatorial use of alternatively spliced Ig-domains enables the generation of an estimated 18,000 isoform-specific homophilic receptor pairs. Although isoform diversity of Dscam is unique to arthropods, recent genetic analysis of vertebrate DSCAM( Down Syndrome Cell Adhesion Molecule) genes has revealed an intriguing conservation of molecular functions underlying neural wiring. This review covers the multiple functions of Dscam across different species highlighting its remarkable versatility as well as its conserved basic functions in neural development. We discuss how an unprecedented expansion of complex alternative splicing has been uniquely employed by arthropods to generate diverse surface receptors, important for cell-cell communication, molecular self-recognition in neurons, and innate immune defenses. We end with a speculative hypothesis reconciling the striking differences in Dscam and DSCAM gene structures with their conserved functions in molecular recognition underlying neural circuit formation.

AB Drug combination therapies for central nervous system (CNS) demyelinating diseases including multiple sclerosis (MS) are gaining momentum over monotherapy. Over the past decade, both in vitro and in vivo studies established that statins (HMG-CoA reductase inhibitors) and rolipram (phosphodiesterase-4 inhibitor; blocks the degradation of intracellular cyclic AMP) can prevent the progression of MS in affected individuals via different mechanisms of action. In this study, we evaluated the effectiveness of lovastatin (LOV) and rolipram (RLP) in combination therapy to promote neurorepair in an inflammatory CNS demyelination model of MS, experimental autoimmune encephalomyelitis (EAE). Combination treatment with suboptimal doses of these drugs in an established case of EAE (clinical disease score >= 2.0) significantly attenuated the infiltration of inflammatory cells and protected myelin sheath and axonal integrity in the CNS. It was accompanied with elevated level of cyclic AMP and activation of its associated protein kinase A. Interestingly, combination treatment with these drugs impeded neurodegeneration and promoted neurorepair in established EAE animals (clinical disease score >= 3.5) as verified by quantitative real-time polymerase chain reaction, immunohistochemistry and electron microscopic analyses. These effects of combination therapy were minimal and/or absent with either drug alone in these settings. Together, these data suggest that combination therapy with LOV and RLP has the potential to provide neuroprotection and promote neurorepair in MS, and may have uses in other related CNS demyelinating diseases.

AB Helicobacter pylori colonizes the acidic gastric environment, in contrast to all other neutralophiles, whose acid resistance and tolerance responses allow only gastric transit. This acid adaptation is dependent on regulation of gene expression in response to pH changes in the periplasm and cytoplasm. The cytoplasmic histidine kinase, HP0244, which until now was thought only to regulate flagellar gene expression via its cognate response regulator, HP0703, was found to generate a response to declining medium pH. Although not required for survival at pH 4.5, HP0244 is required for survival at pH 2.5 with 10 mM urea after 30 min. Transcriptional profiling of a HP0244 deletion mutant grown at pH 7.4 confirmed the contribution of HP0244 to sigma(54) activation via HP0703 to coordinate flagellar biosynthesis by a pH-independent regulon that includes 14 flagellar genes. Microarray analysis of cells grown at pH 4.5 without urea revealed an additional 22 genes, including 4 acid acclimation genes (ureA, ureB, ureI, and amiE) that are positively regulated by HP0244. Additionally, 86 differentially expressed genes, including 3 acid acclimation genes (ureF, rocF [arginase], and ansB [asparaginase]), were found in cells grown at pH 2.5 with 30 mM urea. Hence, HP0244 has, in addition to the pH-independent flagellar regulon, a pH-dependent regulon, which allows adaptation to a wider range of environmental acid conditions. An acid survival study using an HP0703 mutant and an electrophoretic mobility shift assay with in vitro-phosphorylated HP0703 showed that HP0703 does not contribute to acid survival and does not bind to the promoter regions of several genes in the HP0244 pH-dependent regulon, suggesting that there is a pathway outside the HP0703 regulon which transduces the acid-responsive signal sensed by HP0244.

AB The highly homologous proteins ezrin, radixin, and moesin link proteins to the actin cytoskeleton. The two family members expressed in T cells, ezrin and moesin, are implicated in promoting T cell activation and polarity. To elucidate the contributions of ezrin and moesin, we conducted a systematic analysis of their function during T cell activation. In response to TCR engagement, ezrin and moesin were phosphorylated in parallel at the regulatory threonine, and both proteins ultimately localized to the distal pole complex (DPC). However, ezrin exhibited unique behaviors, including tyrosine phosphorylation and transient localization to the immunological synapse before movement to the DPC. To ask whether these differences reflect unique requirements for ezrin vs moesin in T cell signaling, we generated mice with conditional deletion of ezrin in mature T cells. Ezrin(-/-) T cells exhibited normal immunological synapse organization based upon localization of protein kinase C-theta, talin, and phospho-ZAP70. DPC localization of CD43 and RhoGDP dissociation inhibitor, as well as the novel DPC protein Src homology region 2 domain-containing phosphatase-1, was also unaffected. However, recruitment of three novel DPC proteins, ezrin binding protein of 50 kDa, Csk binding protein, and the p85 subunit of PI3K was partially perturbed. Biochemical analysis of ezrin(-/-) T cells or T cells suppressed for moesin using small interfering RNA showed intact early TCR signaling, but diminished levels of IL-2. The defects in IL-2 production were more pronounced in T cells deficient for both ezrin and moesin. These cells also exhibited diminished phospholipase C-gamma 1 phosphorylation and calcium flux. We conclude that despite their unique movement and phosphorylation patterns, ezrin and moesin function together to promote T cell activation. The Journal of Immunology, 2009, 182: 1021-1032.

AB Cysteinyl Ieukotrienes (cys-LTs) induce inflammatory responses through type 1 (CysLT(1)R) and type 2 (CysLT(2)R) cys-LT receptors and activate mast cells in vitro. We previously demonstrated that cys-LTs cross-desensitized IL-4-primed primary human mast cells (hMCs) to stimulation with the nucleotide uridine diphosphate (UDP). We now report that hMCs, mouse bone marrow-derived mast cells (mBMMCs), and the human MC line LAD2 all express UDP-selective P2Y6 receptors that cooperate with CysLT(1)R to promote cell survival and chemokine generation by a pathway involving reciprocal ligand-mediated cross-talk. Leukotriene (LT) D(4), the most potent CysLT, R ligand, and UDP both induced phosphorylation of ERK and prolonged the survival of cytokine-starved hMCs and mBMMCs. ERK activation and cytoprotection in response to either ligand were attenuated by treatment of the cells with a selective P2Y6 receptor antagonist (MRS2578), which did not interfere with signaling through recombinant CysLT(1)R. Surprisingly, both UDP and LTD(4)-mediated ERK activation and cytoprotection were absent in mBMMCs lacking CysLT(1)R and the biosynthetic enzyme LTC(4) synthase, implying a requirement for a cys-LT-mediated autocrine loop. In IL-4-primed LAD2 cells, LTD(4) induced the generation of MIP-1 beta, a response blocked by short hairpin RNA-mediated knockdown of CysLT(1)R or P2Y6 receptors, but not of CysLT(2)R. Thus, CysLT(1)R and P2Y6 receptors, which are coexpressed on many cell types of innate immunity, reciprocally amplify one another's function in mast cells through endogenous ligands.

AB We performed a retrospective observational study of thirty-four persons with late onset of Huntington Disease (HD) (onset range 60-79 years). CAG trinucleotide expansion size ranged from 38-44 repeats. Even at this late age a significant negative correlation (r = -0.421, p < 0.05) was found between the length of repeat and age of onset. important characteristics of these older subjects were: (1) Most (68%) were the first in the family to have a diagnosis of HD, (2) Motor problems were the initial symptoms at onset, (3) Disability increased and varied from mild to severe (4) Disease duration was somewhat shorter (12 years) than that reported for mid life onset, (5) Death was often related to diseases of old age, Such as cancer and cerebrovascular disease, (6) Serious falls were a major risk and (7) Global dementia may be associated with coincident Alzheimer disease. Recognizing these characteristics will help physicians and other health care providers better identify and follow the late onset presentation of this disease. Published by Elsevier B.V.

AB We assessed differences in the character and specificity of autologous neutralizing antibodies (ANAbs) against individual viral variants of the quasispecies in a cohort of drug-naive subjects with long-term controlled human immunodeficiency virus type 1 (HIV-1) infection and moderate levels of broad heterologous neutralizing antibodies (HNAb). Functional plasma virus showed continuous env evolution despite a short time frame and low levels of viral replication. Neutralization-sensitive variants dominated in subjects with intermittent viral blips, while neutralization-resistant variants predominated in elite controllers. By sequence analysis of this panel of autologous variants with various sensitivities to neutralization, we identified more than 30 residues in envelope proteins (Env) associated with resistance or sensitivity to ANAbs. The appearance of new sensitive variants is consistent with a model of continuous selection and turnover. Strong ANAb responses directed against autologous Env variants are present in long-term chronically infected individuals, suggesting a role for these responses in contributing to the durable control of HIV replication.

TI Functional Consequences of Human Immunodeficiency Virus Escape from an

AB The observed association between HLA-B*13 and control of human immunodeficiency virus type 1 (HIV-1) infection has been linked to the number of Gag-specific HLA-B*13-restricted cytotoxic T-cell (CTL) responses identified. To date, the Gag escape mutations described that result in an in vitro fitness cost to the virus have been located within structural protein p24 only. Here we investigated the hypothesis that CTL escape mutations within other regions of HIV Gag may also reduce viral fitness and contribute to immune control. We analyzed an HLA-B*13-restricted CTL response toward an epitope in p1 Gag, RQANFLGKI(429-437) (RI9), where amino acid variation at Gag residues 436 and 437 is associated with HLA-B*13 expression. In this work, we assessed the impact of amino acid substitutions at these positions on CTL recognition and on HIV-1 fitness. We demonstrated that substitutions I437L and I437M largely abrogate CTL recognition and reduce viral fitness while variants K436R and I437V have only a marginal effect on recognition and fitness. Examination of the patterns of protein synthesis indicated that the loss of fitness in the I437L and I437M mutants is associated with the accumulation of unprocessed Gag precursors. A significant reduction in ribosomal frameshifting efficiency was observed with I437M, suggesting that this mechanism contributes to the observed reduced fitness of this virus. These studies illustrate the apparent trade-off available to the virus between evasion of CTL recognition in p1 Gag and the functional consequences for viral fitness.

AB Upon viral infection, the major defense mounted by the host immune system is activation of the interferon (IFN)-mediated antiviral pathway, which is mediated by IFN regulatory factors (IRFs). In order to complete their life cycle, viruses must modulate host IFN-mediated immune responses. Despite its association with significant human health problems, activities of Epstein-Barr virus (EBV), a human tumor-inducing herpesvirus, to evade host IFN-mediated innate immunity have not been well characterized. To search for EBV genes that block IFN signal transduction, we carried out a screening of EBV open reading frames for their abilities to block IFN-alpha/beta-mediated luciferase expression upon Sendai virus infection. This screening demonstrates that EBV LF2 tegument protein specifically interacts with the central inhibitory association domain of IRF7, and this interaction leads to inhibition of the dimerization of IRF7, which suppresses IFN-alpha production and IFN-mediated immunity. This demonstrates a novel immune evasion mechanism of EBV LF2 in blocking cellular IRF7-mediated innate immunity.

AB The infant leukemia-associated gene Ott1 (Rbm15) has broad regulatory effects within murine hematopoiesis. However, germ line Ott1 deletion results in fetal demise prior to embryonic day 10.5, indicating additional developmental requirements for Ott1. The spen gene family, to which Ott1 belongs, has a transcriptional activation/repression domain and RNA recognition motifs and has a significant role in the development of the head and thorax in Drosophila melanogaster. Early Ott1-deficient embryos show growth retardation and incomplete closure of the notochord. Further analysis demonstrated placental defects in the spongiotrophoblast and syncytiotrophoblast layers, resulting in an arrest of vascular branching morphogenesis. The rescue of the placental defect using a conditional allele with a trophoblast-sparing cre transgene allowed embryos to form a normal placenta and survive gestation. This outcome showed that the process of vascular branching morphogenesis in Ott1-deficient animals was regulated by the trophoblast compartment rather than the fetal vasculature. Mice surviving to term manifested hyposplenia and abnormal cardiac development. Analysis of global gene expression of Ott1-deficient embryonic hearts showed an enrichment of hypoxia-related genes and a significant alteration of several candidate genes critical for cardiac development. Thus, Ott1-dependent pathways, in addition to being implicated in leukemogenesis, may also be important for the pathogenesis of placental insufficiency and cardiac malformations.

AB The intracellular signaling mechanisms underlying the pathogenesis of cardiac diseases are not fully understood. We report here that selective deletion of Shp2, an SH2-containing cytoplasmic tyrosine phosphatase, in striated muscle results in severe dilated cardiomyopathy in mice, leading to heart failure and premature mortality. Development of cardiomyopathy in this mouse model is coupled with insulin resistance, glucose intolerance, and impaired glucose uptake in striated muscle cells. Shp2 deficiency leads to upregulation of leukemia inhibitory factor-stimulated phosphatidylinositol 3-kinase/Akt, Erk5, and Stat3 pathways in cardiomyocytes. Insulin resistance and impaired glucose uptake in Shp2-deficient mice are at least in part due to impaired protein kinase C-zeta/lambda and AMP-kinase activities in striated muscle. Thus, we have generated a mouse line modeling human patients suffering from cardiomyopathy and insulin resistance. This study reinforces a concept that a compound disease with multiple cardiovascular and metabolic disturbances can be caused by a defect in a single molecule such as Shp2, which modulates multiple signaling pathways initiated by cytokines and hormones.

AB Patients assigned file diagnostic ICD-9-CM code for Parkinson's disease (PD) in an administrative database may not truly carry that diagnosis because Of the Various error sources. Improved ability to identify PD cases within databases may facilitate specific research goals. Experienced chart reviewers abstracted the working diagnosis of all 577 patients assigned diagnostic code 332.0 (PD) during 1 year at it VA Healthcare System. We then tested the ability of various algorithms making use of PD and non-PD diagnostic codes, specialty of clinics visited, and medication prescription data to predict the abstracted working diagnosis. Chart review determined 436 (75.6%) patients to be PD or Possibly PD, and 141 (24.4%) to lie Not PD. Our tiered consensus algorithm preferentially used data from specialists over nonspecialists improved PPV to 83.2% (P = 0.003 vs. baseline). When presence of a PD prescription was an additional criterion, PPV increased further to 88.2% (P = 0.04 vs. without medication criterion), but sensitivity decreased from 87.4 to 77.1% (P = 0.0001). We demonstrate that algorithms provide better identification of PD cases than using a single Occurrence of the diagnostic code for PD, and modifications of such algorithms can be tuned to maximize parameters that best meet the goals of a particular database query. 0 2008 Movement Disorder Society

SOMATOTOPIC ORGANIZATION
AB Clinical, experimental and neuroimaging studies indicate that the cerebellum is involved in neural processes beyond the motor domain. Cerebellar somatotopy has been shown for motor control, but topographic organization of higher-order functions has not yet been established. To determine whether existing literature supports the hypothesis of functional topography in the human cerebellum, we conducted an activation likelihood estimate (ALE) meta-analysis of neuroimaging studies reporting cerebellar activation in selected task categories: motor (n=7 studies), somatosensory (n=2), language (n=11), verbal working memory (n=8), spatial (n=8), executive function (n= 8) and emotional processing (n= 9). In agreement with previous investigations, sensorimotor tasks activated anterior lobe (lobule V) and adjacent lobule VI, with additional foci in lobule VIII. Motor activation was in VIIIA/B; somatosensory activation was confined to VIIIB. The posterior lobe was involved in higher-level tasks. ALE peaks were identified in lobule VI and Crus I for language and verbal working memory; lobule VI for spatial tasks; lobules VI, Crus I and VIIB for executive functions; and lobules VI, Crus I and medial VII for emotional processing. Language was heavily right-lateralized and spatial peaks left-lateralized, reflecting crossed cerebro-cerebellar projections. Language and executive tasks activated regions of Crus I and lobule VII proposed to be involved in prefrontal-cerebellar loops. Emotional processing involved vermal lobule VII, implicated in cerebellar-limbic circuitry. These data provide support for an anterior sensorimotor vs. posterior cognitive/emotional dichotomy in the human cerebellum. Prospective studies of multiple domains within single individuals are necessary to better elucidate neurobehavioral structure-function correlations in the cerebellar posterior lobe.

AB Visual short-term memory (VSTM) relies on a distributed network including sensory-related, posterior regions of the brain and frontal areas associated with attention and cognitive control. To characterize the. ne temporal details of processing within this network, we recorded event-related potentials (ERPs) while human subjects performed a recognition-memory task. The task's difficulty was graded by varying the perceptual similarity between the items held in memory and the probe used to access memory. The evaluation of VSTM's contents against a test stimulus produced clear similarity-dependent differences in ERPs as early as 156 ms after probe onset. Posterior recording sites were the first to reflect the difficulty of the analysis, preceding their frontal counterparts by about 50 ms. Our results suggest an initial feed-forward interaction underlying stimulus-memory comparisons, consistent with the idea that visual areas contribute to temporary storage of visual information for use in ongoing tasks. This study provides a first look into early neural activity underlying the processing of visual information in short-term memory. (C) 2008 Elsevier Inc. All rights reserved.

AB Background In patients with multivessel coronary artery disease who are undergoing percutaneous coronary intervention ( PCI), coronary angiography is the standard method for guiding the placement of the stent. It is unclear whether routine measurement of fractional flow reserve ( FFR; the ratio of maximal blood flow in a stenotic artery to normal maximal flow), in addition to angiography, improves outcomes.
Methods In 20 medical centers in the United States and Europe, we randomly assigned 1005 patients with multivessel coronary artery disease to undergo PCI with implantation of drug- eluting stents guided by angiography alone or guided by FFR measurements in addition to angiography. Before randomization, lesions requiring PCI were identified on the basis of their angiographic appearance. Patients assigned to angiography- guided PCI underwent stenting of all indicated lesions, whereas those assigned to FFR- guided PCI underwent stenting of indicated lesions only if the FFR was 0.80 or less. The primary end point was the rate of death, nonfatal myocardial infarction, and repeat revascularization at 1 year.
Results The mean (+/- SD) number of indicated lesions per patient was 2.7+/- 0.9 in the angiography group and 2.8+/- 1.0 in the FFR group ( P = 0.34). The number of stents used per patient was 2.7+/- 1.2 and 1.9+/- 1.3, respectively ( P< 0.001). The 1- year event rate was 18.3% ( 91 patients) in the angiography group and 13.2% ( 67 patients) in the FFR group ( P = 0.02). Seventy- eight percent of the patients in the angiography group were free from angina at 1 year, as compared with 81% of patients in the FFR group ( P = 0.20).
Conclusions Routine measurement of FFR in patients with multivessel coronary artery disease who are undergoing PCI with drug- eluting stents significantly reduces the rate of the composite end point of death, nonfatal myocardial infarction, and repeat revascularization at 1 year.

AB Background. It is generally accepted that all transplants are not rejected in the same fashion. However, the extrinsic and intrinsic factors that control the recognition and rejection of a particular allograft by the host are not well characterized.
Methods. We compared the mechanisms underlying the response with donor antigens by T cells activated after transplantation of fully allogeneic skin and corneal grafts in mice.
Results. In corneal-transplanted mice, the CD4(+) T-cell response was exclusively mediated by T cells recognizing minor antigens in an indirect fashion and producing low levels of interleukin-2. In contrast, skin grafts elicited both direct and indirect CD4(+) T-cell responses primarily directed to major histocompatibility complex antigens and characterized by high interleukin-2 levels. Although CD8(+) T-cells producing gamma interferon were activated directly in both skin-and cortical-grafted mice, only CD8(+) T cells from skin-transplanted mice Mounted a cytotoxic response. Next, we investigated whether failure of corneal transplants to induce a CD4(+) direct alloresponse is due to their poor immunogenicity or due to the site of placement (eye). We observed that corneas transplanted under the skin and splenocytes transplanted in the eye were both capable of inducing direct CD4(+) T-cell alloreactivity.
Conclusions. This shows that failure of orthotopic corneal allotransplants to elicit a CD4(+) T-cell direct alloresponse is associated with the combination of two factors, their low immunogenicity and the immune-privileged properties of the eye.

AB The diversity of HIV-1 and human genetics complicates our ability to determine the impact of treatment during primary HIV-1 infection on disease outcome. Here, we show, in a small group infected with virtually identical HIV-1 strains and treated during primary HIV-1 infection, that patients expressing protective human leucocyte antigen alleles had lower viral loads following treatment discontinuation. These data suggest that genetic factors play an important role in the outcome of HIV-1 infection despite early therapy.

ID COMPLETE DISLOCATION; INJURIES; SEPARATIONS; SHOULDER; COMPLEX; REPAIR
AB Background: Symptomatic Acromioclavicular (AC) dislocations have historically been surgically treated with Coracoclavicular (CC) ligament reconstruction with transfer of the Coracoacromial (CA) ligament. Tensioning the CA ligament is the key to success.
Methods: Seventeen patients with chronic, symptomatic Type III AC joint or acute Type IV and V injuries were treated surgically. The distal clavicle was resected and stabilized with CC ligament reconstruction using the CA ligament. The CA ligament was passed into the medullary canal and tensioned, using a modified 'docking' technique. Average follow-up was 29 months (range 12-57).
Results: Postoperative ASES and pain significantly improved in all patients ( p = 0.001). Radiographically, 16 (94%) maintained reduction, and only 1 (6%) had a recurrent dislocation when he returned to karate 3 months postoperatively. His ultimate clinical outcome was excellent.
Conclusion: The docking procedure allows for tensioning of the transferred CA ligament and healing of the ligament in an intramedullary bone tunnel. Excellent clinical results were achieved, decreasing the risk of recurrent distal clavicle instability.

AB Drugs of abuse produce psychomotor stimulation as one of their characteristic behavioral effects. Single administration of opiates stimulates motor activity via effects on gamma-aminobutyric acid (GABA) and dopamine transmission in the ventral tegmental area (VTA). Adenosine A(1) receptor agonists inhibit VTA GABAergic and dopaminergic transmission and are predicted to alter the behavioral effects of opiates. This study examined the effects of intra-VTA administration of selective adenosine A(1) receptor agonist N-6-cyclopentyladenosine (CPA) and antagonist 8-cyclopentyl-1,3-dimethylxanthine (CPT) on morphine-induced motor stimulation in C57BL/6 mice. It also examined the effects of CPA on morphine's activation of VTA neurons projecting to limbic and cortical regions including the nucleus accumbens (NAc), anterior cingulate cortex (ACg) and prelimbic cortex (PrL) via quantitation of immediate-early gene c-Fos protein in these regions. Mice received subcutaneous morphine and intra-VTA administration of CPA and then automated motor activity was measured. Morphine treatment induced both motor activity and Fos immunoreactivity in the NAc, ACg and PrL suggesting that behavioral stimulation is produced by neural activation in these regions. Intra-VTA CPA administration produced a dose-dependent inhibition of morphine-induced motor stimulation and blocked c-Fos induction in all three regions. Intra-VTA CPT treatment had no effects on motor activity or on morphine-induced motor stimulation. VTA adenosine A(1) agonist inhibition of morphine's effects on motor activity and of neural activation of VTA projections suggests that these neurons and their regulation are critical to morphine's stimulant effects. Adenosine A(1) receptor agonists and purinergic modulators may represent useful treatment approaches for blocking the behavioral effects of opiates. Published by Elsevier B.V.

AB Background: Consumption of cured/smoked meat and fish leads to the formation of carcinogenic N-nitroso compounds in the acidic stomach. This study investigated whether consumed cured/smoked meat and fish, the major dietary resource for exposure to nitrites and nitrosamines, is associated with childhood acute leukemia.
Methods: A population-based case-control study of Han Chinese between 2 and 20 years old was conducted in southern Taiwan. 145 acute leukemia cases and 370 age-and sex-matched controls were recruited between 1997 and 2005. Dietary data were obtained from a questionnaire. Multiple logistic regression models were used in data analyses.
Results: Consumption of cured/smoked meat and fish more than once a week was associated with an increased risk of acute leukemia (OR = 1.74; 95% CI: 1.15-2.64). Conversely, higher intake of vegetables (OR = 0.55; 95% CI: 0.37-0.83) and bean-curd (OR = 0.55; 95% CI: 0.34-0.89) was associated with a reduced risk. No statistically significant association was observed between leukemia risk and the consumption of pickled vegetables, fruits, and tea.
Conclusion: Dietary exposure to cured/smoked meat and fish may be associated with leukemia risk through their contents of nitrites and nitrosamines among children and adolescents, and intake of vegetables and soy-bean curd may be protective.

AB Objectives
This study sought to determine the association of pre-hospital electrocardiograms (ECGs) and the timing of reperfusion therapy for patients with ST-segment elevation myocardial infarction (STEMI).
Background
Pre-hospital ECGs have been recommended in the management of patients with chest pain transported by emergency medical services (EMS).
Methods
We evaluated patients with STEMI from the NCDR (National Cardiovascular Data Registry) ACTION (Acute Coronary Treatment and Intervention Outcomes Network) registry who were transported by EMS from January 1, 2007, through December 31, 2007. Patients were stratified by the use of pre-hospital ECGs, and timing of reperfusion therapy was compared between the 2 groups.
Results
A total of 7,098 of 12,097 patients (58.7%) utilized EMS, and 1,941 of these 7,098 EMS transport patients (27.4%) received a pre-hospital ECG. Among the EMS transport population, primary percutaneous coronary intervention was performed in 92.1% of patients with a pre-hospital ECG versus 86.3% with an in-hospital ECG, whereas fibrinolytic therapy was used in 4.6% versus 4.2% of patients. Median door-to-needle times for patients receiving fibrinolytic therapy (19 min vs. 29 min, p = 0.003) and median door-to-balloon times for patients undergoing primary percutaneous coronary intervention (61 min vs. 75 min, p < 0.0001) were significantly shorter for patients with a pre-hospital ECG. A suggestive trend for a lower risk of in-hospital mortality was observed with pre-hospital ECG use (adjusted odds ratio: 0.80, 95% confidence interval: 0.63 to 1.01).
Conclusions
Only one-quarter of these patients transported by EMS receive a pre-hospital ECG. The use of a pre-hospital ECG was associated with a greater use of reperfusion therapy, faster reperfusion times, and a suggested trend for a lower risk of mortality.

TI S100A7, a Novel Alzheimer's Disease Biomarker with Non-Amyloidogenic
alpha-Secretase Activity Acts via Selective Promotion of ADAM-10
SO PLOS ONE
LA English
DT Article
AB Alzheimer's disease (AD) is the most common cause of dementia among older people. At present, there is no cure for the disease and as of now there are no early diagnostic tests for AD. There is an urgency to develop a novel promising biomarker for early diagnosis of AD. Using surface-enhanced laser desorption ionization-mass spectrometry SELDI-(MS) proteomic technology, we identified and purified a novel 11.7-kDa metal-binding protein biomarker whose content is increased in the cerebrospinal fluid (CSF) and in the brain of AD dementia subjects as a function of clinical dementia. Following purification and protein-sequence analysis, we identified and classified this biomarker as S100A7, a protein known to be involved in immune responses. Using an adenoviral- S100A7 expression system, we continued to examine the potential role of S100A7 in AD amyloid neuropathology in in vitro model of AD. We found that the expression of exogenous S100A7 in primary cortico-hippocampal neuron cultures derived from Tg2576 transgenic embryos inhibits the generation of beta-amyloid (A beta)(1-42) and A beta(1-40) peptides, coincidental with a selective promotion of "non- amyloidogenic'' alpha-secretase activity via promotion of ADAM (a disintegrin and metalloproteinase)-10. Finally, a selective expression of human S100A7 in the brain of transgenic mice results in significant promotion of alpha-secretase activity. Our study for the first time suggests that S100A7 may be a novel biomarker of AD dementia and supports the hypothesis that promotion of S100A7 expression in the brain may selectively promote alpha-secretase activity in the brain of AD precluding the generation of amyloidogenic peptides. If in the future we find that S1000A7 protein content in CSF is sensitive to drug intervention experimentally and eventually in the clinical setting, S100A7 might be developed as novel surrogate index (biomarker) of therapeutic efficacy in the characterization of novel drug agents for the treatment of AD.

AB Mutations in the HER2 kinase domain have been identified in human clinical lung cancer specimens. Here we demonstrate that inducible expression of the most common HER2 mutant (HER2(YVMA)) in mouse lung epithelium causes invasive adenosquamous carcinomas restricted to proximal and distal bronchioles. Continuous expression of HER2YVMA is essential for tumor maintenance, suggesting a key role for HER2 in lung adenosquamous tumorigenesis. Preclinical studies assessing the in vivo effect of erlotinib, trastuzumab, BIBW2992, and/or rapamycin on HER2(YVMA) transgenic mice or H1781 xenografts with documented tumor burden revealed that the combination of BIBW2992 and rapamycin is the most effective treatment paradigm causing significant tumor shrinkage. Immunohistochemical analysis of lung tumors treated with BIBW2992 and rapamycin combination revealed decreased phosphorylation levels for proteins in both upstream and downstream arms of MAPK and Akt/mTOR signaling axes, indicating inhibition of these pathways. Based on these findings, clinical testing of the BIBW2992/rapamycin combination in non-small cell lung cancer patients with tumors expressing HER2 mutations is warranted.

AB The PI 3-phosphatase PTEN (phosphatase and tensin homologue deleted on chromosome 10), one of the most important tumor suppressors, must associate with the plasma membrane to maintain appropriate steady-state levels of phosphatidylinositol 3,4,5triphosphate. Yet the mechanism of membrane binding has received little attention and the key determinants that regulate localization, a phosphatidylinositol 4,5-bisphosphate (PIP2) binding motif and a cluster of phosphorylated C-terminal residues, were not included in the crystal structure. We report that membrane binding requires PIP2 and show that phosphorylation regulates an intramolecular interaction. A truncated version of the enzyme, PTEN1-351, bound strongly to the membrane, an effect that was reversed by co-expression of the remainder of the molecule, PTEN352-403. The separate fragments associated in vitro, an interaction dependent on phosphorylation of the C-terminal cluster, a portion of the PIP2 binding motif, integrity of the phosphatase domain, and the CBR3 loop. Our investigation provides direct evidence for a model in which PTEN switches between open and closed states and phosphorylation favors the closed conformation, thereby regulating localization and function. Small molecules targeting these interactions could potentially serve as therapeutic agents in antagonizing Ras or PI3K-driven tumors. The study also stresses the importance of determining the structure of the native enzyme.

AB Background: While ultrasound (US) has continued to expedite diagnosis and therapy for critical care physicians inside the hospital system, the technology has been slow to diffuse into the pre-hospital system. Given the diagnostic benefits of thoracic ultrasound (TUS), we sought to evaluate image recognition skills for two important TUS applications; the identification of B-lines (used in the US diagnosis of pulmonary edema) and the identification of lung sliding and comet tails (used in the US diagnosis of pneumothorax). In particular we evaluated the impact of a focused training module in a pre-hospital system that utilizes physicians as pre-hospital providers.
Methods: 27 Paris Service D'Aide Medicale Urgente (SAMU) physicians at the Hopital Necker with varying levels of US experience were given two twenty-five image recognition pre-tests; the first test had examples of both normal and pneumothorax lung US and the second had examples of both normal and pulmonary edema lung US. All 27 physicians then underwent the same didactic training modules. A post-test was administered upon completing the training module and results were recorded.
Results: Pre and post-test scores were compared for both the pneumothorax and the pulmonary edema modules. For the pneumothorax module, mean test scores increased from 10.3 +/- 4.1 before the training to 20.1 +/- 3.5 after (p < 0.0001), out of 25 possible points. The standard deviation decreased as well, indicating a collective improvement. For the pulmonary edema module, mean test scores increased from 14.1 +/- 5.2 before the training to 20.9 +/- 2.4 after (p < 0.0001), out of 25 possible points. The standard deviation decreased again by more than half, indicating a collective improvement.
Conclusion: This brief training module resulted in significant improvement of image recognition skills for physicians both with and without previous ultrasound experience. Given that rapid diagnosis of these conditions in the pre-hospital system can change therapy, especially in systems where physicians can integrate this information into treatment decisions, the further diffusion of this technology would seem to be beneficial and deserves further study.

TI Insulin, the Insulin-Like Growth Factor Axis, and Mortality in Patients
With Nonmetastatic Colorectal Cancer

AB Purpose
Obesity, sedentary lifestyle, and Western dietary pattern have been linked to increased risk of cancer recurrence and mortality among patients with surgically resected colorectal cancer. Excess energy balance leads to increased circulating insulin and depressed levels of circulating insulin-like growth factor binding protein (IGFBP) -1, which promote cancer cell growth in preclinical models.
Patients and Methods
Among 373 patients diagnosed with nonmetastatic colorectal cancer between 1991 and 2004, we performed a prospective observational study nested within two large US cohorts to evaluate the association between mortality and prediagnosis circulating C-peptide (a marker of insulin secretion), IGFBP-1, insulin-like growth factor-I (IGF-I), and IGFBP-3.
Results
Compared with patients in the bottom quartile, patients in the top quartile of plasma C-peptide had an age-adjusted hazard ratio (HR) for death of 1.87 (95% CI, 1.04 to 3.36; P = .03 for trend), whereas those in the top quartile of circulating IGFBP-1 had a significant reduction in mortality (HR = 0.48; 95% CI, 0.28 to 0.84; P = .02 for trend). Little change in these estimates was noted after adjusting for other covariates known or suspected to influence survival. No associations were noted between mortality and IGF-I or IGFBP-3, which are two components of the IGF axis not closely correlated with lifestyle factors.
Conclusion
Among patients with surgically resected colorectal cancer, higher levels of prediagnosis plasma C-peptide and lower levels of prediagnosis plasma IGFBP-1 were associated with increased mortality. Circulating insulin and IGFBP-1 are potential mediators of the association between lifestyle factors and mortality after colorectal cancer resection.

AB Purpose
The PI3K/Akt/mTOR pathway is activated in the majority of pancreatic cancers, and inhibition of this pathway has antitumor effects in preclinical studies. We performed a multi-institutional, single-arm, phase II study of RAD001(everolimus), an oral inhibitor of mTOR, in patients who experienced treatment failure on first-line therapy with gemcitabine.
Patients and Methods
Thirty-three patients with gemcitabine-refractory, metastatic pancreatic cancer were treated continuously with RAD001 at 10 mg daily. Prior treatment with fluorouracil in the perioperative setting was allowed. Patients were observed for toxicity, treatment response, and survival.
Results
Treatment with single-agent RAD001 was well-tolerated; the most common adverse events were mild hyperglycemia and thrombocytopenia. No patients were removed from the study because of drug-related adverse events. No complete or partial treatment responses were noted, and only seven patients (21%) had stable disease at the first restaging scans performed at 2 months. Median progression-free survival and overall survival were 1.8 months and 4.5 months, respectively. One patient (3%) had a biochemical response, defined as >= 50% reduction in serum CA19-9.
Conclusion
Although well-tolerated, RAD001 administered as a single-agent had minimal clinical activity in patients with gemcitabine-refractory, metastatic pancreatic cancer. Future studies in metastatic pancreatic cancer should assess the combination of mTOR inhibitors with other agents and/or examine inhibitors of other components of the PI3K/Akt/mTOR pathway.

SURVIVAL; AID
AB Purpose
Adjuvant! Online (www.adjuvantonline.org) is a software model that predicts the benefit of adjuvant therapy for women with early-stage breast cancer. The model has been validated, is widely consulted, and has been shown to influence patient choices in the clinical setting. Adjuvant! requires the clinician to input patient age, tumor size, grade, hormone receptor status, number of positive lymph nodes, and comorbidity level. Because comorbidity is strongly and independently associated with survival, this study tested the hypothesis that Adjuvant! predictions would be sensitive to comorbidity inputs.
Methods
Investigators used single-variable deterministic sensitivity analysis to evaluate the effect of varying each input of the model independently for three representative case examples based on National Comprehensive Cancer Network guidelines (NCCN). The main outcome of interest was 10-year mortality prediction.
Results
The analyses show that Adjuvant!'s 10-year mortality predictions are most sensitive to patients' comorbidity levels and the extent of nodal involvement for the cases, particularly among older women. Comorbidity was the most influential input except in younger women, aged 40 years.
Conclusion
The Adjuvant! model is sensitive to patient comorbidity, and impact on the model outputs are significant enough that they are likely to affect physician recommendations and patients' treatment choices. For example, incorrect assessments of comorbidities could lead physicians to overtreat or undertreat a patient who is in a gray zone relative to the NCCN guidelines. These results point to the importance of accurately assessing comorbidities in patients with breast cancer when using Adjuvant! and highlight the need for a standardized process of comorbidity ascertainment.

CHEMOTHERAPY; CHLORAMBUCIL
AB Purpose
Nucleoside analogs (NAs) are considered as appropriate agents in the treatment of Waldenstrom macroglobulinemia (WM), a lymphoplasmacytic lymphoma. Sporadic reports on increased incidence of transformation to high-grade non-Hodgkin's lymphoma and development of therapy-related myelodysplasia/acute leukemia (t-MDS/AML) among patients with WM treated with NAs prompted us to examine the incidence of such events in a large population of patients with WM.
Patients and Methods
We examined the incidence of these events in 439 patients with WM, 193 and 136 of whom were previously treated with and without an NA, respectively, and 110 of whom had similar long-term follow-up without treatment. The median follow-up for all patients was 5 years.
Results
Overall, 12 patients (6.2%) either developed transformation (n = 9; 4.7%) or developed t-MDS/AML (n = 3; 1.6%) among NA-treated patients, compared with one patient (0.4%) who developed transformation in the non-NA treated group (P < .001); no such events occurred among untreated patients. Transformation and t-MDS/AML occurred at a median of 5 years from onset of NA therapy. The median survival of NA-treated patients who developed transformation did not differ from other NA-treated patients as a result of effective salvage treatment used for transformed disease. However, all NA-treated patients who developed t-MDS/AML died at a median of 5 months.
Conclusion
These data demonstrate an increased incidence of disease transformation to high-grade NHL and the development of t-MDS/AML among patients with WM treated with NAs.

AB Mutations of the lipid phosphatase FIG4 that regulates PI(3,5)P(2) are responsible for the recessive peripheral-nerve disorder CMT4J. We now describe nonsynonymous variants of FIG4 in 2% (9/473) of patients with amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS). Heterozygosity for a deleterious allele of FIG4 appears to be a risk factor for ALS and PLS, extending the list of known ALS genes and increasing the clinical spectrum of FIG4-related diseases.

AB Estrogen receptor (ER) antagonists have been widely used for breast cancer treatment, but the efficacy and drug resistance remain to be clinical concerns. The purpose of this Study was to determine whether the extracts of coptis, an anti-inflammatory herb, improve the anticancer efficacy of ER antagonists. The results showed that the combined treatment of ER antagonists and the crude extract of coptis or its purified compound berberine conferred synergistic growth inhibitory effect on MCF-7 cells (ER+), but not On MDA-MB-231 cells (ER-). Similar results were observed in the combined treatment of fulvestrant, a specific aromatase antagonist. Analysis of the expression of breast cancer related genes indicated that EGFR, HER2. bcl-2, and COX-2 were significantly downregulated, while IFN-beta and p21 were remarkably upregulated by berberine. Our results Suggest that coptis extracts could be promising adjuvant to ER antagonists in ER positive breast cancer treatment through regulating expression Of Multiple genes. (C) 2008 Elsevier Inc.

AB MicroRNA (miRNA) control has emerged as a critical regulatory principle in the mammalian immune system. Genetic ablation of the miRNA machinery, as well as loss or deregulation of certain individual miRNAs, severely compromises immune development and response and can lead to immune disorders like autoimmunity and cancer. Although individual miRNAs modulate protein output from hundreds of target genes, they may impact physiological processes by regulating the concentrations of just a few key cellular proteins that may be components of a single or of functionally interrelated pathways in a given cellular context.

AB Eukaryotic DNA is bound and interpreted by numerous protein complexes in the context of chromatin. A description of the full set of proteins that regulate specific loci is critical to understanding regulation. Here, we describe a protocol called proteomics of isolated chromatin segments (PICh) that addresses this issue. PICh uses a specific nucleic acid probe to isolate genomic DNA with its associated proteins in sufficient quantity and purity to allow identification of the bound proteins. Purification of human telomeric chromatin using PICh identified the majority of known telomeric factors and uncovered a large number of novel associations. We compared proteins found at telomeres maintained by the alternative lengthening of telomeres (ALT) pathway to proteins bound at telomeres maintained by telomerase. We identified and validated several proteins, including orphan nuclear receptors, that specifically bind to ALT telomeres, establishing PICh as a useful tool for characterizing chromatin composition.

AB Experimental results from studies with inbred mice and their syngeneic tumors indicated that the inoculation of semi-allogeneic cell hybrids (derived from the fusion between syngeneic tumor cells and an allogeneic cell line) protects the animal host from a subsequent lethal challenge with unmodified syngeneic tumor cells. Semi-allogeneic somatic cell hybrids were generated by the fusion of EL-4 T lymphoma cells (H-2(b)) and BALB/c-derived renal adenocarcinoma RAG cells (H-2(d)). Cell hybrids were injected intra-peritoneally (i.p.) in C57BL/6 mice (H-2(b)) before challenging the mice with a tumorigenic dose of EL-4 cells. Semi-allogeneic tumor cell hybrids could not form a tumor in the animal host because they expressed allogeneic determinants (H-2(d)) and were rejected as a transplant. However, they conferred protection against a tumorigenic challenge of EL-4 cells compared to control mice that were mock-vaccinated with i.p.-injected phosphate-buffered saline (PBS) and in which EL-4 lymphomas grew rapidly to a large size in the peritoneal cavity. Screening of spleen-derived RNA by means of focused microarray technology showed up-regulation of genes involved in the Th-1-type immune response and in the activation of dendritic antigen-presenting cells (APC). The results of our studies confirm the role of APC in mediating the immune protection induced by semi-allogeneic vaccines by activating a Th-1 response; these studies also reveal that semi-allogeneic vaccines are able to interfere with or even block the tumor-mediated induction of immune tolerance, a key mechanism underlying the suppression of antitumor immunity in the immune competent host.

AB Hyperactivity of the hypothalamo-pituitary-adrenocortical (HPA) axis is linked with age-related decrements in cognition and neuronal survival. However. the nature and extent of age-related HPA axis deficits vary considerably across and indeed, within strains. The current study was designed to assess variance in HPA axis function using two rodent models commonly used in aging Studies: Fischer 344 (F344) and F344/Brown-Norway F1 hybrid rats (F344/BN). We examined both basal and stress-induced ACTH and corticosterone (CORT) release in two stress contexts thought to differ in intensity: novel environment ('mild') and restraint ('intense'). Variability of the data was tested with a modification of the Brown-Forsythe test of homoscedasticity. The results indicated that F344 rats exhibit greater peak HPA responses. Furthermore, in most cases variability was increased in aged rats relative to young and middle-aged rats of the same strain, indicative of the emergence of individual differences in stress responsivity amongst older rats. The results suggest that these older rat strains may be useful models to further assess individual differences in neuroendocrine aging. Published by Elsevier Inc.

AB We have developed a physiologically based mathematical model, with parameters derived from published experimental data, to simulate the regulatory effects of the leptin pathway on murine energy homeostasis. Model outcomes are consistent with data reported in the literature and reproduce key characteristics of the energy regulatory system, including compensatory responses that counteract changes in body weight and the failure of this ability when the leptin pathway is disrupted. Our model revealed the possibility of multiple steady states for body weight. It also provided a unified theoretical framework for two historically antagonistic hypotheses regarding body weight regulation ("set-point" versus "settling point"). Finally, our model has identified potential avenues for future investigations.

AB Context Many individuals take vitamins in the hopes of preventing chronic diseases such as cancer, and vitamins E and C are among the most common individual supplements. A large- scale randomized trial suggested that vitamin E may reduce risk of prostate cancer; however, few trials have been powered to address this relationship. No previous trial in men at usual risk has examined vitamin C alone in the prevention of cancer.
Objective To evaluate whether long- term vitamin E or C supplementation decreases risk of prostate and total cancer events among men.
Design, Setting, and Participants The Physicians' Health Study II is a randomized, double- blind, placebo- controlled factorial trial of vitamins E and C that began in 1997 and continued until its scheduled completion on August 31, 2007. A total of 14 641 male physicians in the United States initially aged 50 years or older, including 1307 men with a history of prior cancer at randomization, were enrolled.
Intervention Individual supplements of 400 IU of vitamin E every other day and 500 mg of vitamin C daily.
Main Outcome Measures Prostate and total cancer.
Results During a mean follow- up of 8.0 years, there were 1008 confirmed incident cases of prostate cancer and 1943 total cancers. Compared with placebo, vitamin E had no effect on the incidence of prostate cancer ( active and placebo vitamin E groups, 9.1 and 9.5 events per 1000 person- years; hazard ratio [ HR], 0.97; 95% confidence interval [ CI], 0.85- 1.09; P=. 58) or total cancer ( active and placebo vitamin E groups, 17.8 and 17.3 cases per 1000 person- years; HR, 1.04; 95% CI, 0.95- 1.13; P=. 41). There was also no significant effect of vitamin C on total cancer ( active and placebo vitamin C groups, 17.6 and 17.5 events per 1000 person- years; HR, 1.01; 95% CI, 0.92- 1.10; P=. 86) or prostate cancer ( active and placebo vitamin C groups, 9.4 and 9.2 cases per 1000 person- years; HR, 1.02; 95% CI, 0.90- 1.15; P=. 80). Neither vitamin E nor vitamin C had a significant effect on colorectal, lung, or other site- specific cancers. Adjustment for adherence and exclusion of the first 4 or 6 years of follow- up did not alter the results. Stratification by various cancer risk factors demonstrated no significant modification of the effect of vitamin E on prostate cancer risk or either agent on total cancer risk.
Conclusions In this large, long- term trial of male physicians, neither vitamin E nor C supplementation reduced the risk of prostate or total cancer. These data provide no support for the use of these supplements for the prevention of cancer in middle- aged and older men.

AB Context Deep brain stimulation is an accepted treatment for advanced Parkinson disease ( PD), although there are few randomized trials comparing treatments, and most studies exclude older patients.
Objective To compare 6- month outcomes for patients with PD who received deep brain stimulation or best medical therapy.
Design, Setting, and Patients Randomized controlled trial of patients who received either deep brain stimulation or best medical therapy, stratified by study site and patient age ( < 70 years vs >= 70 years) at 7 Veterans Affairs and 6 university hospitals between May 2002 and October 2005. A total of 255 patients with PD ( Hoehn and Yahr stage >= 2 while not taking medications) were enrolled; 25% were aged 70 years or older. The final 6- month follow- up visit occurred in May 2006.
Intervention Bilateral deep brain stimulation of the subthalamic nucleus ( n= 60) or globus pallidus ( n= 61). Patients receiving best medical therapy ( n= 134) were actively managed by movement disorder neurologists.
Main Outcome Measures The primary outcome was time spent in the "on" state ( good motor control with unimpeded motor function) without troubling dyskinesia, using motor diaries. Other outcomes included motor function, quality of life, neurocognitive function, and adverse events.
Results Patients who received deep brain stimulation gained a mean of 4.6 h/ d of on time without troubling dyskinesia compared with 0 h/ d for patients who received best medical therapy ( between group mean difference, 4.5 h/ d [ 95% CI, 3.7- 5.4 h/ d]; P <. 001). Motor function improved significantly ( P <. 001) with deep brain stimulation vs best medical therapy, such that 71% of deep brain stimulation patients and 32% of best medical therapy patients experienced clinically meaningful motor function improvements ( >= 5 points). Compared with the best medical therapy group, the deep brain stimulation group experienced significant improvements in the summary measure of quality of life and on 7 of 8 PD quality- of- life scores ( P <. 001). Neurocognitive testing revealed small decrements in some areas of information processing for patients receiving deep brain stimulation vs best medical therapy. At least 1 serious adverse event occurred in 49 deep brain stimulation patients and 15 best medical therapy patients ( P <. 001), including 39 adverse events related to the surgical procedure and 1 death secondary to cerebral hemorrhage.
Conclusion In this randomized controlled trial of patients with advanced PD, deep brain stimulation was more effective than best medical therapy in improving on time without troubling dyskinesias, motor function, and quality of life at 6 months, but was associated with an increased risk of serious adverse events.

THERAPY; TOMOTHERAPY; DELIVERY; COMPENSATION; OPTIMIZATION; COLLIMATION
AB The idea of delivering intensity-modulated radiation therapy (IMRT) with a multileaf collimator in a continuous dynamic mode during a single rotation of the gantry has recently gained momentum both in research and industry. In this note we investigate the potential of this Single-Arc IMRT technique at a conceptual level. We consider the original theoretical example case from Brahme et al that got the field of IMRT started. Using analytical methods, we derive deliverable intensity 'landscapes' for Single-Arc as well as standard IMRT and Tomotherapy. We find that Tomotherapy provides the greatest flexibility in shaping intensity landscapes and that it allows one to deliver IMRT in a way that comes close to the ideal case in the transverse plane. Single-Arc and standard IMRT make compromises in different areas. Only in relatively simple cases that do not require substantial intensity modulation will Single-Arc be dosimetrically comparable to Tomotherapy. Compared with standard IMRT, Single-Arc could be dosimetrically superior in certain cases if one is willing to accept the spreading of low dose values over large volumes of normal tissue. In terms of treatment planning, Single-Arc poses a more challenging optimization problem than Tomotherapy or standard IMRT. We conclude that Single-Arc holds potential as an efficient IMRT technique especially for relatively simple cases. In very complex cases, Single-Arc may unduly compromise the quality of the dose distribution, if one tries to keep the treatment time below 2 min or so. As with all IMRT techniques, it is important to explore the tradeoff between plan quality and the efficiency of its delivery carefully for each individual case.

AB Memories evolve. After learning something new, the brain initiates a complex set of post-learning processing that facilitates recall (i.e., consolidation). Evidence points to sleep as one of the determinants of that change. But whenever a behavioral study of episodic memory shows a benefit of sleep, critics assert that sleep only leads to a temporary shelter from the damaging effects of interference that would otherwise accrue during wakefulness. To evaluate the potentially active role of sleep for verbal memory, we compared memory recall after sleep, with and without interference before testing. We demonstrated that recall performance for verbal memory was greater after sleep than after wakefulness. And when using interference testing, that difference was even more pronounced. By introducing interference after sleep, this study confirms an experimental paradigm that demonstrates the active role of sleep in consolidating memory, and unmasks the large magnitude of that benefit.

AB Background-Arterial stiffness increases with age and contributes to the pathogenesis of systolic hypertension and cardiovascular disease in the elderly. Knowledge about the pathophysiological processes that determine arterial stiffness may help guide therapeutic approaches.
Methods and Results-We related 7 circulating biomarkers representing distinct biological pathways (C-reactive protein, aldosterone-to-renin ratio, N-terminal proatrial natriuretic peptide and B-type natriuretic peptide, plasminogen activator inhibitor-1, fibrinogen, and homocysteine) to 5 vascular function measures (central pulse pressure, carotid-femoral pulse-wave velocity, mean arterial pressure, forward pressure wave amplitude [all measures of conduit artery stiffness], and augmented pressure, an indicator of wave reflection) in 2000 Framingham Offspring Study participants (mean age, 61 years; 55% women). Tonometry measures were obtained on average 3 years after the biomarkers were measured. In multivariable linear regression models adjusting for covariates, the biomarker panel was significantly associated with all 5 vascular measures (P < 0.003 for all). On backward elimination, the aldosterone-to-renin ratio was positively associated with each stiffness measure (P <= 0.002 for all). In addition, C-reactive protein was positively related to augmented pressure (P = 0.0003), whereas plasminogen activator inhibitor-1 was positively associated with mean arterial pressure (P = 0.003), central pulse pressure (P = 0.001), and forward pressure wave (P = 0.01).
Conclusions-Our cross-sectional data on a community-based sample suggest a distinctive pattern of positive associations of biomarkers of renin-angiotensin-aldosterone system activation with pan-arterial vascular stiffness, plasminogen activator inhibitor-1 with central vascular stiffness indices, and C-reactive protein with wave reflection. These observations support the notion of differential influences of biological pathways on vascular stiffness measures. (Circulation. 2009; 119: 37-43.)

AB Background-Adherence to evidence-based guidelines for treatment of stroke or transient ischemic attack is suboptimal. We sought to establish whether participation in Get With the Guidelines-Stroke was associated with improvements in adherence.
Methods and Results-This prospective, nonrandomized, national quality improvement program measured adherence to guideline recommendations in 322 847 hospitalized patients discharged with a diagnosis of ischemic stroke or transient ischemic attack. A volunteer sample of 790 US academic and community hospitals participated from 2003 through 2007. The main outcome measures were change in adherence over time to 7 prespecified performance measures and a composite measure (total number of interventions provided in eligible patients divided by total number of care opportunities among eligible patients). Generalized estimating equations were used to identify factors associated with improvement. Participation in Get With the Guidelines-Stroke was associated with improvements in the 7 individual and 1 composite measures from baseline to the fifth year: intravenous thrombolytics (42.09% versus 72.84%), early antithrombotics (91.46% versus 97.04%), deep vein thrombosis prophylaxis (73.79% versus 89.54%), discharge antithrombotics (95.68% versus 98.88%), anticoagulation for atrial fibrillation (95.03% versus 98.39%), lipid treatment for low-density lipoprotein >100 mg/dL (73.63% versus 88.29%), smoking cessation (65.21% versus 93.61%), and composite (83.52% versus 93.97%) (P < 0.0001 for all comparisons). Multivariate analysis showed that time in Get With the Guidelines-Stroke was associated with a 1.18-fold yearly increase in the odds of fulfilling care opportunities that was independent of secular trends.
Conclusions-Get With the Guidelines-Stroke participation was associated with increased adherence to all stroke performance measures. Markedly improved stroke care was seen in all hospitals regardless of size, geography, and teaching status. (Circulation. 2009; 119: 107-115.)

AB Background: The amyloid beta-peptide is a ubiquitous peptide, which is prone to aggregate forming soluble toxic oligomers and insoluble less-toxic aggregates. The intrinsic and external/environmental factors that determine A beta aggregation in vivo are poorly understood, as well as the cellular meaning of this process itself. Genetic data as well as cell biological and biochemical evidence strongly support the hypothesis that A beta is a major player in the onset and development of Alzheimer's disease. In addition, it is also known that A beta is involved in Inclusion Body Myositis, a common myopathy of the elderly in which the peptide accumulates intracellularly.
Results: In the present work, we found that intracellular A beta aggregation in muscle cells of Caenorhabditis elegans overexpressing A beta peptide is affected by two single amino acid substitutions, E22G (Arctic) and V18A (NIC). Both variations show decrease intracellular amyloidogenesis compared to wild type A beta. We show that intracellular amyloid aggregation of wild type A beta is accelerated by Cu(2+) and diminished by copper chelators. Moreover, we demonstrate through toxicity and behavioral assays that A beta-transgenic worms display a higher tolerance to Cu(2+) toxic effects and that this resistance may be linked to the formation of amyloid aggregates.
Conclusion: Our data show that intracellular A beta amyloid aggregates may trap excess of free Cu(2+) buffering its cytotoxic effects and that accelerated intracellular A beta aggregation may be part of a cell protective mechanism.

AB The selectins are cell adhesion proteins that must resist applied forces to mediate leukocyte tethering and rolling along the endothelium and have 2 conformational states. Selectin-ligand bond dissociation increases only modestly with applied force, and exhibits catch bond behavior in a low-force regime where bond lifetimes counterintuitively increase with increasing force. Both allosteric and sliding-rebinding models have emerged to explain catch bonds. Here, we introduce a large residue into a cleft that opens within the lectin domain to stabilize the more extended, high-affinity selectin conformation. This mutation stabilizes the high-affinity state, but surprisingly makes rolling less stable. The position of the mutation in the lectin domain provides evidence for an allosteric pathway through the lectin domain, connecting changes at the lectin-EGF interface to the distal binding interface.

CELL-ADHESION; DOMAIN; FORCE; RECEPTOR; SHEAR; FLOW
AB Selectins are adhesion molecules that resist large tensile forces applied by hydrodynamic forces to leukocytes binding to vessel walls. In crystals, the liganded (high-affinity) and unliganded (low-affinity) conformations differ in orientation between their tandem lectin and EGF domains. I examine how tensile force exerted on a selectin-ligand complex in vivo could favor the more extended, high-affinity conformation. Allostery is transmitted from the EGF-lectin domain interface to the ligand-binding interface on the lectin domain, 30 angstrom away. Trp-1 of the lectin domain and the long axis of the EGF domain form an L-shaped prybar that is welded together by hydrogen bonds to the Trp-1 alpha-amino group. Pivoting of the prybar induced by force demolishes an interface between the Trp-1 side chain and the lectin domain at a switch1 region. These changes are transmitted by rigid body movement of the switch2 region to rearrangements in the switch3 region at the ligand binding site. Another switch region corresponds to a single residue in the EGF domain with large effects on ligand binding and rolling adhesion. Allostery in selectins, and the alignment of tensile force on a selectin-ligand complex with the transition pathway for conformational change, explain much of the structural basis for selectin mechanochemistry.

AB Members of the poxvirus family have been investigated for their applications as vaccines and expression vectors and, more recently, because of concern for their potential as biological weapons. Vaccinia virus, the prototypic member, evolves through multiple forms during its replication. Here, we show a surprising way by which vaccinia hijacks coatomer for early viral biogenesis. Whereas coatomer forms COPI vesicles in the host early secretory system, vaccinia formation bypasses this role of coatomer, but instead, depends on coatomer interacting with the host KDEL receptor. To gain insight into the viral roles of these two host proteins, we have detected them on the earliest recognized viral forms. These findings not only suggest insights into early vaccinia biogenesis but also reveal an alternate mechanism by which coatomer acts.

AB Several clinical and genetic studies have reported gender differences in obsessive-compulsive disorder (OCD). Previously, we conducted a linkage genome scan using multipoint allele-sharing methods to test for linkage in 219 families participating in the OCD Collaborative Genetics Study. When these families were stratified by proband's gender, suggestive linkage to chromosome 11p15 at marker D11S2362 (KAC(all) = 2.92, P = 0.00012) was detected in families with male probands, but not in the ones with female probands. We have since conducted fine mapping with a denser microsatellite marker panel in the region of 11p15, and detected a significant linkage signal at D11S4146 (KAC(all) = 5.08, P < 0.00001) in the families of male probands. Subsequently, 632 SNPs were genotyped spanning a 4.0 Mb region of the 1 LOD unit interval surrounding the linkage peak in the original families and an additional 165 families. Six SNPs were associated with OCD (P < 0.001): two SNPs were identified when all the families were included, and four SNPs only in male proband families. No SNP showed significant association with the OCD phenotype only in the families with a female proband. The results suggest a possible gender effect in the etiology of OCD. (c) 2008 Wiley-Liss, Inc.

AB Cochlear hair cells use SK2 Currents to shape responses to cholinergic efferent feedback from the brain. Using SK2(-/-) mice, we demonstrate that, in addition to their previously defined role in modulating hair cell membrane potentials, SK2 channels are necessary for long-term survival of olivocochlear fibers and synapses. Loss of the SK2 gene also results a loss of electrically driven olivocochlear effects in vivo. and down regulation of ryanodine receptors involved in calcium-induced calcium release, the main inducer of nAChR evoked SK2 activity. Generation Of double-null mice lacking both the alpha 10 nAChR gene, loss of which results in hypertrophied olivocochlear terminals, and the SK2 gene, recapitulates the SK2(-/-) synaptic phenotype and gene expression, and also leads to clown regulation of alpha 9 nAChR gene expression. The data suggest a hierarchy of activity necessary to maintain early olivocochlear synapses at then, targets, with SK2 serving an epistatic, upstream, role to the nAChRs. (C) 2008 Elsevier Inc.

AB We report the experimental implementation of optical diffraction tomography for quantitative 3D mapping of refractive index in live biological cells. Using a heterodyne Mach-Zehnder interferometer, we record complex field images of light transmitted through a sample with varying directions of illumination. To quantitatively reconstruct the 3D map of complex refractive index in live cells, we apply optical diffraction tomography based on the Rytov approximation. In this way, the effect of diffraction is taken into account in the reconstruction process and diffraction-free high resolution 3D images are obtained throughout the entire sample volume. The quantitative refractive index map can potentially serve as an intrinsic assay to provide the molecular concentrations without the addition of exogenous agents and also to provide a method for studying the light scattering properties of single cells.

AB Background: Cystatin C has been proposed as an alternative marker of renal function. We sought to determine whether participants randomized to episodic use of antiretroviral therapy guided by CD4(+) cell count (drug conservation) had altered cystatin C levels compared with those randomized to Continuous antiretroviral therapy (viral suppression) in the Strategies for Management of Antiretroviral Therapy trial, and to identify factors associated with increased cystatin C.
Methods: Cystatin C was measured in plasma collected at randomization, 1, 2, 4, 8 and 12 months after randomization in a random sample of 249 and 250 participants in the drug conservation and viral suppression groups, respectively. Logistic regression was used to model the odds of at least 0.15 mg/dl increase in cystatin C (1 SD) in the first month after randomization, adjusting for demographic and clinical characteristics.
Results: At randomization, mean (SD) cystatin C level was 0.99 (0.26 mg/dl) and 1.01 (0.28 mg/dl) in the drug conservation and viral Suppression arms, respectively (P = 0.29). In the first month after randomization, 21.8 and 10.6% had at least 0.15 mg/dl increase in cystatin C in the drug conservation and viral suppression arms, respectively (P=0.0008). The difference in cystatin C between the treatment arms was maintained through 1 year after randomization. After adjustment, participants in the viral suppression arm had significantly reduced odds of at least 0.15 mg/dl increase in cystatin C in the first month (odds ratio 0.42; 95% confidence interval 0.23-0.74, P = 0.0023).
Conclusion: These results demonstrate that interruption of antiretroviral therapy is associated with an increase in cystatin C, which may reflect worsened renal function. (C) 2009 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins

AB Previously, we demonstrated that mitochondria from denervated muscle exhibited dramatically higher Amplex Red dependent fluorescence (thought to be highly specific for hydrogen peroxide) compared with control muscle mitochondria. We now demonstrate that catalase only partially inhibits the Amplex Red signal in mitochondria from denervated muscle. In contrast, ebselen (a glutathione peroxidase mimetic and inhibitor of fatty acid hydroperoxides) significantly inhibits the Amplex Red signal. This suggests that the majority of the Amplex Red signal in mitochondria from denervated muscle is not derived from hydrogen peroxide. Because Amplex Red cannot react with substrates in the lipid environment, we hypothesize that lipid hydroperoxides formed within the mitochondrial lipid bilayer are released as fatty acid hydroperoxides and react with the Amplex Red probe. We also suggest that the release of fatty acid hydroperoxides from denervated muscle mitochondria may be an important determinant of muscle atrophy. In support of this, muscle atrophy and the Amplex Red signal are inhibited in caloric restricted mice and in transgenic mice that overexpress the lipid hydroperoxide-detoxifying enzyme glutathione peroxidase 4. Finally, we propose that cytosolic phospholipase A(2) may be a potential source of these hydroperoxides.

AB The perception of pathogen or microbe- associated molecular pattern molecules by plants triggers a basal defense response analogous to animal innate immunity and is defined partly by the deposition of the glucan polymer callose at the cell wall at the site of pathogen contact. Transcriptional and metabolic profiling in Arabidopsis mutants, coupled with the monitoring of pathogen- triggered callose deposition, have identified major roles in pathogen response for the plant hormone ethylene and the secondary metabolite 4- methoxy- indol- 3- ylmethylglucosinolate. Two genes, PEN2 and PEN3, are also necessary for resistance to pathogens and are required for both callose deposition and glucosinolate activation, suggesting that the pathogen- triggered callose response is required for resistance to microbial pathogens. Our study shows that well-studied plant metabolites, previously identified as important in avoiding damage by herbivores, are also required as a component of the plant defense response against microbial pathogens.

AB The destruction of infectious pathogens by photodynamic therapy (PDT) is an emerging modality. We demonstrated the efficacy of PDT for the management of cutaneous leishmaniasis in our previous studies. However, much remains to be done for the improvement of PDT regimens. The modulation of the immune response by photochemistry is an exciting but under-explored area of PDT research. The goal of this study is to understand the mechanisms of the augmentation of the host immune response after PDT of cutaneous leishmaniasis (CL). We found that PDT with phenoxiazine analogues was capable for induction of Th1 immune response due to stimulation of IL-12 production by dendritic cells. Single PDT treatment facilitated fast healing of the CL lesions due to effective parasite eradication and augmentation of the immune system. Comparative study with different photosensitizers (PS) (porphyrins, pehnoxiazines) demonstrated different immunomodulating properties of PDT depending on chemical class of PS. Knowing the particular profiles and immunomodulating properties of the pertinent PSs allows us to select the optimal PS with regards to both the photodestructive and immunostimulating potential.

AB Multi-drug resistant Acinetobacter baumanii infections represent a growing problem, especially in traumatic wounds and burns suffered by military personnel injured in Middle Eastern conflicts. Effective treatment using traditional antibiotics can be extremely difficult and new antimicrobial approaches are being investigated. One of these antimicrobial alternatives could be the combination of non-toxic photosensitizers (PS) and visible light known as photodynamic therapy (PDT). We report on the establishment of a new mouse model of full thickness thermal burns infected with a bioluminescent derivative of a clinical Iraqi isolate of A. baumannii and its PDT treatment by topical application of a PS produced by covalent conjugation chlorin(e6) to polyethylenimine followed by illumination of the burn surface with red light. Application of 10 8 A. baumannii cells to the surface of 10-second burns made on the dorsal surface of shaved female BALB/c mice led to chronic infections that lasted on average 22 days characterized by a remarkably stable bacterial bioluminescence. PDT carried out on day 0 soon after applying bacteria gave over three logs of loss of bacterial luminescence in a light exposure dependent manner, while PDT carried out on day 1 and day 2 gave approximately a 1.7-log reduction. Application of PS dissolved in 10% or 20% DMSO without light gave only modest reduction in bacterial luminescence from mouse burns. Some bacterial regrowth in the treated burn was observed but was generally modest. It was also found that PDT did not lead to inhibition of wound healing. The data suggest that PDT may be an effective new treatment for multi-drug resistant localized A. baumannii infections.

Singlet oxygen is an active species in photodynamic therapy, and we are developing two instruments for PDT researchers with the goal of a real-time dosimeter for singlet oxygen. We discuss both an ultra-sensitive point sensor, and an imaging system that provides simultaneous 2D maps of the photosensitizer fluorescence and the singlet oxygen emission. Results of in vitro tests to characterize the sensors and preliminary in vivo results are presented.

AB Photodynamic therapy (PDT) has been successfully used to treat many malignancies, and has afforded highly encouraging results in skin cancers such as basal cell carcinoma. However, pigmented melanoma remains a notable exception from the range of tumors treated by PDT largely due to the fact that melanin has high absorption of light in wavelength regions where most clinically approved photosensitizers (PS) absorb light (600-690 nm). Moreover, melanoma cells sequester exogenous molecules including photosensitizers inside melanosomes. The aforementioned drawbacks of the clinically used PS have motivated us to search for new classes of PS with improved spectral properties, such as bacteriochlorins (BC) to be used in PDT of melanoma. To overcome the PDT-resistance mechanisms of melanoma, particularly the high optical absorption of melanin, three near-infrared (NIR) absorbing synthetic stable BC were used in PDT treatment of melanoma. Dose and fluence dependent cell killing, intracellular localization (particularly in melanosomes), and correlation between the melanin level and cell death were examined. Intracellular melanosomes are ruptured after illumination as shown by electron microscopy. The best in vitro performing BC were tested upon delivery in micellar nanoparticles against a mouse pigmented melanoma. Two of the BC were effective at significantly lower concentrations (<0.5 mu M) than common photosensitizers in present use.

AB Epigenetic mechanisms, which involve DNA methylation and histone modifications, result in the heritable silencing of genes without a change in their coding sequence. However, these changes must be actively maintained after each cell division rendering them a promising target for pharmacologic inhibition. DNA methyltransferase inhibitors like 5-aza-deoxycytidine (5-aza-dC) induce and/or up-regulate the expression of MAGE-type antigens in human and mice cancer cells. Photodynamic therapy (PDT) has been shown to be an effective locally ablative anti-cancer treatment that has the additional advantage of stimulating tumor-directed immune response. We studied the effects of a new therapy that combined the demethylating agent 5-aza-dC with PDT in the breast cancer model 4T1 syngenic to immunocompetent BALB/c mice. PDT was used as a locally ablating tumor treatment that is capable of eliciting strong and tumor directed immune response while 5-aza-dC pretreatment was used promote de novo induction of the expression of P1A. protein. This is the mouse homolog of human MAGE family antigens and is reported to function as a tumor rejection antigen in certain mouse tumors. This strategy led to an increase in PDT-mediated immune response and better treatment outcome. These results strongly suggest that the MAGE family antigens are important target for PDT mediated immune response but that their expression can be silenced by epigenetic mechanisms. Therefore the possibility that PDT can be combined with epigenetic strategies to elicit anti-tumor immunity in MAGE-positive tumor models is highly clinically significant and should be studied in detail.

AB Anti-tumor immunity is stimulated after PDT due a number of factors including: the acute inflammatory response caused by PDT, release of antigens from PDT-damaged tumor cells, priming of the adaptive immune system to recognize tumor-associated antigens (TAA), and induction of heat-shock proteins. The induction of specific CD8+ T-lymphocyte cells that recognize major histocompatibility complex class I (MHC-I) restricted epitopes of TAAs is a highly desirable goal in cancer therapy as it would allow the treatment of tumors that may have already metastasized. The PDT killed tumor cells may be phagocytosed by dendritic cells (DC) that then migrate to draining lymph nodes and prime naive T-cells that recognize TAA epitopes. We have carried out in vivo PDT with a BPD-mediated vascular regimen using a pair of BALB/c mouse colon carcinomas: CT26 wild type expressing the naturally occurring retroviral antigen gp70 and CT26. CL25 additionally expressing beta-galactosidase (b-gal) as a model tumor rejection antigen. PDT of CT26. CL25 cured 100% of tumors but none of the CT26WT tumors (all recurred). Cured CT26. CL25 mice were resistant to rechallenge. Moreover mice with two bilateral CT26. CL25 tumors that had only one treated with PDT demonstrated spontaneous regression of 70% of untreated contralateral tumors. T-lymphocytes were isolated from lymph nodes of PDT cured mice that recognized a particular peptide specific to b-gal antigen. T-lymphocytes from LN were able to kill CT26. CL25 target cells in vitro but not CT26WT cells as shown by a chromium release assay. CT26. CL25 tumors treated with PDT and removed five days later had higher levels of Th1 cytokines than CT26 WT tumors showing a higher level of immune response. When mice bearing CT26WT tumors were treated with a regimen of low dose cyclophosphamide (CY) 2 days before, PDT led to 100% of cures (versus 0% without CY) and resistance to rechallenge. Low dose CY is thought to deplete regulatory T-cells (Treg, CD4+CD25+foxp3+) and potentiate immune response after PDT in the case of tumors that express self-antigens. These data suggest that PDT alone will stimulate a strong immune response when tumors express a robust antigen, and in cases where tumors express a self-antigen, T-reg depletion can unmask the immune response after PDT.

AB Pancreatic cancer is an aggressive disease with a poor prognosis, usually treated with chemoradiation therapy. Interstitial photodynamic therapy is a potentially effective adjuvant treatment that is under development. In the current study, two orthotopic pancreatic cancer models (AsPC-1 and Panc-1), have been characterized with respect to growth rates, morphology and liposomal drug (Verteporfin) uptake and distribution in SCID mice. Fluorescence of Verteporfin was measured in liver and tumor in vivo using a PDT fluorescence dosimeter with measurements taken before and up to one hour after tail vein injection. Fluorescence reached a plateau by about 15 minutes and did not decrease over the first hour. At time points from 15 minutes to 24 hrs, the internal organs (kidney, spleen, pancreas, tumor, muscle, lung, liver, and skin were excised and scanned on a Typhoon imager. The ratio of fluorescence in tumor versus normal tissues was analyzed with image processing, calculated at each time point and compared to in vivo results. Tissue distribution of Verteporfin in relation to functional vasculature marked by DiOc7 was carried out on frozen sections. Final analysis will result in determination of the ideal time point to administer light to achieve maximum tumor destruction while preserving normal tissue.

AB Pancreatic cancer (PanCa) has a poor prognosis with a 5-year survival rate of only 5%. Photodynamic therapy (PDT) has shown promising results in treating PanCa. Mechanism-based combinations with PDT have enhanced treatment outcome. Agents tested with PDT include Avastin, an antibody against vascular endothelial growth factor (VEGF) which is approved for treating various cancers. Simultaneous delivery of drugs in nano-constructs could improve the treatment response of mechanism based combination therapies. Here, we investigate the effect of neutralizing VEGF using nanotechnology for the delivery of Avastin in combination with PDT. For this we used a construct called "nanocells" in which the photosensitizer was trapped inside polymer nanoparticles and these, with Avastin, were then encapsulated inside liposomes. In vitro, nanocells containing Avastin (NCA) significantly enhanced cytotoxicity in PanCa cells. NCA based PDT also significantly improved treatment response in mice that were orthotopically implanted with PanCa. Avastin delivered extracellularly in combination with PDT did not show any improvement. Here we propose a new paradigm for Avastin-based therapy by combining intracellular delivery of the antibody and PDT using nanotechnology for treating PanCa.

AB beta-lactamase enzyme-activated photosensitizer (beta-LEAP). We aim to exploit drug resistance mechanisms to selectively release photosensitizers (PSs) for a specific photodynamic antimicrobial effect and reduced host tissue damage. Consequently, the fluorescence emission intensity of the PSs increases and allows for the detection of enzyme activity. In this work we sought to evaluate beta-LEAP for use as a sensitive molecular probe. We have reported the enzyme specific antibacterial action of beta-LEAP. Here we report the use of beta-LEAP for the rapid functional definition of a beta-lactamase.

ID PHOTODYNAMIC THERAPY; GEMCITABINE
AB Over the last several decades little progress has been made in the therapy and treatment monitoring of pancreas adenocarcinoma, a devastating and aggressive form of cancer that has a 5-year patient survival rate of 3%. Currently, investigations for the use of interstitial Verteporfin photodynamic therapy (PDT) are being undertaken in both orthotopic xenograft mouse models and in human clinical trials. In the mouse models, magnetic resonance (MR) imaging has been used as a measure of surrogate response to Verteporfin PDT; however, MR imaging alone lacks the molecular information required to assess the metabolic function and growth rates of the tumor immediately after treatment. We propose the implementation of MR-guided fluorescence tomography in conjunction with a fluorescently labeled (IR-Dye 800 CW, LI-COR) epidermal growth factor (EGF) as a molecular measure of surrogate response. To demonstrate the effectiveness of MR-guided diffuse fluorescence tomography for molecular imaging, we have used the AsPC-1 (+EGFR) human pancreatic adenocarcinoma in an orthotopic mouse model. EGF IRDye 800CW was injected 48 hours prior to imaging. MR image sequences were collected simultaneously with the fluorescence data using a MR-coupled diffuse optical tomography system. Image reconstruction was performed multiple times with varying abdominal organ segmentation in order to obtain a optimal tomographic image. It is shown that diffuse fluorescence tomography of the orthotopic pancreas model is feasible, with consideration of confounding fluorescence signals from the multiple organs and tissues surrounding the pancreas. MR-guided diffuse fluorescence tomography will be used to monitor EGF response after photodynamic therapy. Additionally, it provide the opportunity to individualize subsequent therapies based on response to PDT as well as to evaluate the success of combination therapies, such as PDT with chemotherapy, antibody therapy or even radiation.

AB Our laboratory has constructed a custom fluorescence microendoscope for detecting and monitoring tumor nodules in a mouse model of metastatic ovarian carcinoma (OVCA). The microendoscope is being applied for tumor recognition and for quantifying tumor burden reduction following photodynamic therapy (PDT). Benzoporphyrin derivative monoacid ring A (BPD-MA), a photosensitizing agent for PDT, is administered to the mice and imaged with the microendoscope prior to PDT. BPD-MA fluorescence is a convenient means for locating tumor sites and quantifying tumor burden (despite the fact that BPD-MA is a non-targeted contrast agent). The miniature, flexible microendoscope probe is delivered via a 14-gauge catheter for imaging metastases along the outer surfaces of the internal organs and the inner walls of the peritoneal cavity. The minimal invasiveness of this approach facilitates frequent imaging of the mice in order to monitor cancer progression and treatment response. We present promising data for intravital imaging of treatment response following PDT and new developments in the microendoscope instrumentation for improved image quality.

AB Photodynamic therapy has emerged as a possible supplement to the existing protocols for endodontic disinfection. Microbes are known to gain significant ecological advantage when they survive as coaggregates and biofilms in an infected tissue. Such microbial coaggregates and biofilms have been confirmed to play a key role in the pathogenicity of many infections. So far, not many studies have correlated the efficacy of antimicrobial photodynamic inactivation (APDI) to the different modes of bacterial growth. This study aims to evaluate the APDI of 3 strains of Enterococcus faecalis in planktonic phase, in a co-aggregated suspension and in a 4-day old biofilm. The results showed that the biofilm mode of growth offered the greatest resistance to APDI and the inclusion of an efflux pump inhibitor significantly increased the APDI of biofilm bacteria. From this study, we conclude that APDI of bacteria in biofilms is the most challenging and that the use of bacterial efflux pump inhibitors enhances its photodynamic anti-biofilm efficacy.

ID ENDOTHELIAL GROWTH-FACTOR; CANCER; EFFICACY
AB The photophysics and mechanisms of cell killing by photodynamic therapy (PDT) have been extensively studied in recent years, and PDT has received regulatory approval for the treatment of a number of diseases worldwide. As the application of this treatment modality expands with regard to both anatomical sites and diseases, it is important to develop strategies for enhancing PDT outcomes. Our group has focused on developing targeting strategies to enhance PDT for both cancerous as well as anti-microbial applications. In this article, we will discuss photosensitizer modification and conjugation strategies for targeted antimicrobial photodynamic therapy.

AB Photodynamic therapy (PDT) as a treatment modality for infectious disease has shown promise. However, most of the antimicrobial photosensitizers (PS) non-preferentially accumulate in both bacteria and host tissues, causing host tissue phototoxicity during treatment. We have developed a new antimicrobial PDT strategy which exploits beta-lactam resistance mechanism, one of the major drug-resistance bacteria evolved, to achieve enhanced target specificity with limited host damage. Our strategy comprises a prodrug construct with a PS and a quencher linked by beta-lactam ring, resulting in a diminished phototoxicity. This construct, beta-lactamase enzyme-activated-photosensitizer (beta-LEAP), can only be activated in the presence of both light and bacteria, and remains inactive elsewhere such as mammalian tissue. Beta-LEAP construct had shown specific cleavage by purified beta-lactamase and by beta-lactamase over-expressing methicillin resistant Staphylococcus aureus (MRSA). Specific photodynamic toxicity was observed towards MRSA, while dark and light toxicity were equivalent to reference strains. The prodrug design, synthesis and photophysical properties will be discussed.

AB A typical scintillating the sampling calorimeter consists of multiple layers of scintillators coupled to wavelength shifting fibers viewed by a suitable photo-detector. Long clear fibers are used to connect the tiles to the readout modules. We have investigated the use of silicon photomultipliers (SiPMs) at the Super Lagre Hadron Collider (SLHC). Because radiation hardness is the main concern, two sets of radiation data were taken using a 212 MeV proton beam at Massachusetts General Hospital. In the first data set we radiated up to a dose of 3x10(10) protons per cm(2) using diodes from three different manufactures (i.e., FBK, CPTA and Hamamatsu). At a dose of 3x10(10) protons per cm(2) only small effects of PDE loss were detected due to very high dark count always occupying one or more cells in a multi-cell SiPM. A second set of data up to 10(13) protons per cm(2) using very high pixel density MAPDs with upto 40,000 cells per mm(2). After each small radiation dose multiple scope traces were taken to look at the PDE and dark count of the devices. The increase in dark count due to the radiation was compared to the DC leakage current. Also a comparison was made between multi-cell and single-cell samples of the FBK-IRST diodes.

AB We model images and the anatomy that they are derived from as stationary and jointly ergodic random processes. Using an empirically-observed property of anatomy, and data processing inequality arguments, we arrive at optimality criteria for mutual information in the ensemble domain. Using ergodicity, we transfer the criteria to single pairs of images in the spatial domain, where it applies to the popular mutual information-based registration approach that is used in practice.

AB A miniaturized, hermetically-encased, wirelessly-operated retinal prosthesis has been developed for pre-clinical studies in Yucatan minipig animal models. The prosthesis attaches conformally to the outside of the eye and drives a microfabricated thin-film polyimide stimulating electrode array with sputtered iridium oxide electrodes. This array is implanted in the subretinal space using a specially-designed ab externo surgical technique that uses the retina to hold the array in place while leaving the bulk of the prosthesis outside the eye. The implanted device includes a hermetic titanium case containing a 15-channel stimulator chip and discrete circuit components. Feedthroughs from the case connect to secondary power- and data-receiving coils. In addition, long-term in vitro pulse testing was performed on the electrodes to ensure that their lifetime would match that of the hermetic case. The final assembly was tested in vitro to verify wireless operation of the system in biological saline using a custom RF transmitter circuit and primary coils. Stimulation pulse strength, duration and frequency were programmed wirelessly using a custom graphical user interface. Operation of the retinal implant has been verified in vivo in two pigs for up to five and a half months by measuring stimulus artifact on the eye surface using a contact lens electrode.

AB We present a unified probabilistic point process framework to estimate and monitor the instantaneous heartbeat dynamics as related to specific cardiovascular control mechanisms and hemodynamics. Assessment of the model's statistics is established through the Wiener-Volterra theory and a multivariate autoregressive (AR) structure. A variety of instantaneous cardiovascular metrics, such as heart rate (HR), heart rate variability (HRV), respiratory sinus arrhythmia (RSA), and baroreceptor-cardiac reflex (baroreflex), can be rigorously derived within a parametric framework and instantaneously updated with an adaptive algorithm. Nonlinearity metrics, as well as the bispectrum of heartbeat intervals, can also be derived. We have applied the proposed point process framework to a number of recordings under different experimental protocols. Results reveal interesting dynamic trends across different posture/pharmacological/age/heart disease conditions, pointing at our mathematical approach as a promising monitoring tool for an accurate, noninvasive assessment of a large spectrum of cardiovascular diseases and disorders, including hypertension and congestive heart disease.

AB Pressure ulcers are painful sores that arise from prolonged exposure to high pressure points, which restricts blood flow and leads to tissue necrosis. This is a common occurrence among patients with impaired mobility, diabetics and the elderly. In this work, a flexible pressure monitoring system for pressure ulcer prevention has been developed. The prototype consists of 99 capacitive pressure sensors on a 17-cm x 22-cm sheet which is flexible in two dimensions. Due to its low cost, the sensor sheet can be disconnected from the reusable electronics and be disposed of after use, suitable for a clinical setting. Each sensor has a resolution of better than 2-mmHg and a range of 50-mmHg and offset is calibrated in software. Real-time pressure data is displayed on a computer. A maximum sampling rate of 12-Hz allows for continuous monitoring of pressure points.

AB For as many as 30% of epilepsy patients, seizures are poorly controlled with medication alone. For some of these patients surgery may be an option: the brain region responsible for seizure onset may be removed surgically. However, this requires accurate delineation of the seizure onset region. Currently, the key to making this determination is seizure EEG. Therefore, EEG recordings must continue until enough seizures are obtained to determine the onset region; this may take about 5 days to several weeks. In some cases these recordings must be done using invasive electrodes, a procedure that includes substantial risk, discomfort and cost.
In this paper, techniques are developed that use periods of intracranial non-seizure ("rest") EEG to localize epileptogenic networks. Analysis of intracranial EEG (recorded by surface and/or depth electrodes) of 6 epileptic patients shows that certain EEG channels and hence cortical regions are consistently more synchronous ("hypersynchronous") compared to others. It is shown that hypersynchrony seems to strongly correlate with the seizure onset zone; this phenomenon may in the long term allow to determine the seizure onset area(s) from non-seizure EEG, which in turn would enable shorter hospitalizations or even avoidance of semi-chronic implantations all-together.

AB Optical Coherence Tomography (OCT) is an emerging optical technology that has shown great promise for early cancer detection. Using backreflected light to visualize tissue microstructure, OCT can provide information on nuclear size and shape, nuclear-to-cytoplasmic ratio, and the organization and structure of glands. It can also provide functional information, like blood flow, tissue birefringence, etc. These capabilities could potentially be employed in three ways: as a primary diagnostic test to replace biopsy, as a screening tool to direct biopsy, and as a diagnostic tool to guide therapy and monitor therapy response. In this paper we present an application of OCT for pancreatic cancer diagnosis and therapy guidance.

AB Robustness in signal processing is crucial for the purpose of reliably interpreting physiological features from noisy data in biomedical applications. We present a robust algorithm based on the reformulation of a well-known spatial filtering and feature extraction algorithm named Common Spatial Patterns (CSP). We cast the problem of learning CSP into a probabilistic framework, which allows us to gain insights into the algorithm. To address the overfitting problem inherent in CSP, we propose an expectation-maximization (EM) algorithm for learning robust CSP using from a Student-t distribution. The efficacy of the proposed robust algorithm is validated with both simulated and real EEG data.

ID NEURAL SPIKING ACTIVITY; TRAIN DATA; FRAMEWORK; ENSEMBLE
AB Identification of multiple simultaneously recorded neural spike train recordings is an important task in understanding neuronal dependency, functional connectivity, and temporal causality in neural Systems. An assessment of the functional connectivity in a group of ensemble cells was performed using a regularized point process generalized linear model (GLM) that incorporates temporal smoothness or contiguity of the solution. An efficient convex optimization algorithm was then developed for the regularized solution. The point process model was applied to an ensemble of neurons recorded from the cat motor cortex during a skilled reaching task. The implications of this analysis to the coding of skilled movement in primary motor cortex is discussed.

ID HEART-RATE-VARIABILITY; PREDICTS
AB Quantitative evaluation of respiratory sinus arrhythmia (RSA) may provide important information in clinical practice of anesthesia and postoperative care. In this paper, we apply a point process method to assess dynamic RSA during propofol general anesthesia. Specifically, an inverse Gaussian probability distribution is used to model the heartbeat interval, whereas the instantaneous mean is identified by a linear or bilinear bivariate regression on the previous R-R intervals and respiratory measures. The estimated second-order bilinear interaction allows us to evaluate the nonlinear component of the RSA. The instantaneous RSA gain and phase can be estimated with an adaptive point process filter. The algorithm's ability to track non-stationary dynamics is demonstrated using one clinical recording. Our proposed statistical indices provide a valuable quantitative assessment of instantaneous cardiorespiratory control and heart rate variability (HRV) during general anesthesia.

AB Cerebral autoregulation is a homeostatic mechanism which maintains blood flow despite changes in blood pressure in order to meet local metabolic demands. Several mechanisms play a role in cerebral autoregulation in order to adjust vascular tone and caliber of the cerebral vessels, but the exact etiology of the dynamics of these mechanism is not well understood. In this study, we discuss two patient specific models predicting cerebral blood flow velocity during postural change from sitting to standing. One model characterises cerebral autoregulation, the other describes the beat-to-beat distribution of blood flow to the major regions of the brain. Both models have been validated against experimental data from a healthy young subject.

ID PULSE OXIMETRY; SIGNAL
AB Recent reports suggest that photoplethysmography (PPG), which is a component of routine pulse oximetry, may be useful for detecting hypovolemia. An essential step in extracting and analyzing common PPG features is the robust identification of onset and peak locations of the vascular beats, despite varying beat morphologies and major oscillations in the baseline. Some prior reports used manual analysis of the PPG waveform; however, for systematic widespread use, an automated method is required. In this paper, we report an algorithm that automatically detects beat onsets and peaks from noisy field-collected PPG waveforms. We validated the algorithm by clinician evaluation of 100 randomly selected PPG waveform samples. For 99% of the beats, the algorithm was able to credibly identify the onsets and peaks of vascular beats, although the precise locations were ambiguous, given the very noisy data from actual clinical operations. The algorithm appears promising, and future consideration of its diagnostic capabilities and limitations is warranted.

AB Compound screening is a powerful tool to identify new therapeutic targets, drug leads, and elucidate the fundamental mechanisms of biological processes. We report here the results of the first in vivo small-molecule screens for compounds enhancing neuronal regeneration. These screens are enabled by the microfluidic devices we have developed for C. elegans. The devices enable rapid and repeatable animal immobilization which allows high-throughput and precise surgery. Following surgery, animals are exposed to the contents of a small-molecule library and assayed for neuronal regeneration. Using this screening method we have identified several compounds that enhance neural regeneration in vivo.

AB This study uses frequency domain techniques to demonstrate the effect of vibrotactile feedback during continuous multidirectional perturbations of a support platform. Eight subjects with bilateral or unilateral vestibular loss were subjected to two-axis pseudo random surface platform motion while donning a multi-axis feedback balance aid that mapped body tilt estimates onto their trunks via a 3-row by 16-column array of tactile vibrators (tactors). Four tactor display configurations with spatial resolutions ranging between 22.5 degrees and 90 degrees, in addition to the tactors off configuration, were evaluated. Power spectral density (PSD) functions of body sway in the anterior-posterior (A/P) and medial-lateral (M/L) directions were computed at frequencies ranging from 0.0178 Hz to 3.56 Hz. Transfer functions between the platform motion and body sway were also computed. Vibrotactile feedback produced significant decreases in A/P and M/L spectral power, decreased transfer function gains up to a frequency of 1.8 Hz and 0.6 Hz in the A/P and M/L directions, respectively, and increased phase leads above 0.3 Hz. The lack of a consistent difference among tactor configurations argue in favor of the simplest 4-column configuration during multidirectional continuous surface perturbations.

AB We applied mode-decomposition and matched-filtering, both signal processing techniques used to increase the signal-to-noise ratio (SNR), to array CGH data of human meningioma DNA, in order to extract genomic regions of copy-number changes potentially associated with tumor progression. DNA segments from different chromosomes were decomposed into a small number of dominant components (modes), and low-amplitude modes were eliminated. The SNR of the entire segment was increased and it was possible to identify local changes in the data spatial structure, previously indistinguishable due to noise. We applied matched-filtering to the mode-reduced signals, using a normal DNA sequences (averaged over 50 healthy donors) as the template. The residual signals from this process were analyzed to identify disease-related copy number changes.

AB Multiphoton calcium fluorescence imaging has gained prominence as a valuable tool for the study of brain cells, but the corresponding analytical regimes remain rather naive. In this paper, we develop a statistical framework that facilitates principled quantitative analysis of multiphoton images. The proposed methods discriminate the stimulus-evoked response of a neuron from the background firing and image artifacts. We develop a harmonic regression model with colored noise, and estimate the model parameters with computationally efficient algorithms. We apply this model to in vivo characterization of cells from the ferret visual cortex. The results demonstrate substantially improved tuning curve fitting and image contrast.

The work presented in this paper is aimed at creating a new class of adaptive prosthetic and orthotic interfaces involving a capacitive shear stress sensor. The sensor design and transfer function are discussed. A few preliminary test results demonstrating the functionality of the sensor are also presented.

AB The acquisition of high quality MR images of neonatal brains is largely hampered by their characteristically small head size and low tissue contrast. As a result, subsequent image processing and analysis, especially for brain tissue segmentation, are often hindered To overcome this problem, a dedicated phased array neonatal head coil is utilised to improve MR image qualify by effectively combing images obtained from 8 coil elements without lengthening data acquisition time. In addition, a subject-specific atlas based tissue segmentation algorithm is specifically developed for the delineation of fine structures in the acquired neonatal brain MR images. The proposed tissue segmentation method first enhances the sheet-like cortical gray matter (GM) structures in neonatal images with a Hessian filter for generation of cortical GM prior. Then, the prior is combined with our neonatal population atlas to form a cortical enhanced hybrid atlas, which we refer to as the subject-specific atlas. Various experiments are conducted to compare the proposed method with manual segmentation results, as well as with additional two population atlas based segmentation methods. Results show that the proposed method is capable of segmenting the neonatal brain with the highest accuracy, compared to other two methods.

AB Evaluation of baroreflex control of heart rate (HR) has important implications in clinical practice of anesthesia and postoperative care. In this paper, we present a point process method to assess the dynamic baroreflex gain using a closed-loop model of the cardiovascular system. Specifically, the inverse Gaussian probability distribution is used to model the heartbeat interval, whereas the instantaneous mean is identified by a linear or bilinear bivariate regression on the previous R-R intervals and blood pressure (BP) measures. The instantaneous baroreflex gain is estimated in the feedback loop with a point process filter, while the RR -> BP feedforward frequency response is estimated by a Kalman filter. In addition, the instantaneous cross-spectrum and cross-bispectrum (as well as their ratio) can also be estimated. All statistical indices provide a valuable quantitative assessment of the interaction between heartbeat dynamics and hemodynamics during general anesthesia.

AB The authors previously reported speaker-dependent automatic speech recognition accuracy for isolated words using eleven surface-electromyographic (sEMG) sensors in fixed recording locations on the face and neck. The original array of sensors was chosen to ensure ample coverage of the muscle groups known to contribute to articulation during speech production. In this paper we systematically analyzed speech recognition performance from sensor subsets with the goal of reducing the number of sensors needed and finding the best combination of sensor locations to achieve word recognition rates comparable to the full set. We evaluated each of the different possible subsets by its mean word recognition rate across nine speakers using HMM modeling of MFCC and co-activation features derived from the subset of sensor signals. We show empirically that five sensors are sufficient to achieve a recognition rate to within a half a percentage point of that obtainable from the full set of sensors.

AB A state-space method for simultaneously estimating time-dependent rate and higher-order correlation underlying parallel spike sequences is proposed. Discretized parallel spike sequences are modeled by a conditionally independent multivariate Bernoulli process using a log-linear link function, which contains a state of higher-order interaction factors. A nonlinear recursive filtering formula is derived from a log-quadratic approximation to the posterior distribution of the state. Together with a fixed-interval smoothing algorithm, time-dependent log-linear parameters are estimated. The smoothed estimates are optimized via EM-algorithm such that their prior covariance matrix maximizes the expected complete data log-likelihood. In addition, we perform model selection on the hierarchical log-linear state-space models to avoid over-fitting. Application of the method to simultaneously recorded neuronal spike sequences is expected to contribute to uncover dynamic cooperative activities of neurons in relation to behavior.

In particular, we focus on i) line edge roughness (LER), single defects; iii) ionized impurities, iv) acoustic and optical phonons. Results show that the effect of ionized impurities is negligible, while phonons, LER and defects largely limits carrier mobility, especially for narrower GNRs.

AB In the last decade, large arrays of sensors for magnetoencephalography (MEG) (and electroencephalography (EEG)) have become more commonplace, allowing new opportunities for the application of beamforming techniques to the joint problems of signal estimation and noise reduction. We introduce a new approach to noise cancellation, the generalized sidelobe canceller (GSC), itself an alternative to the linearly constrained minimum variance (LCMV) algorithm. The GSC framework naturally fits within the other noise reduction techniques that employ real or virtual reference arrays. Using expository human subject data with strong environmental and biological artifacts, we demonstrate a straightforward sequence of steps for practical noise filtering, applicable to any large array sensor design.

DE Iterative reconstruction; GPU; Computed tomography
AB Although iterative reconstruction techniques (IRTs) have been shown to produce images of superior quality over conventional filtered back projection (FBP) based algorithms, the use of IRT in a clinical setting has been hampered by the significant computational demands of these algorithms. In this paper we present results of our efforts to overcome this hurdle by exploiting the combined computational power of multiple graphical processing units (GPUs). We have implemented forward and backward projection steps of reconstruction on an NVIDIA Tesla S870 hardware using CUDA. We have been able to accelerate forward projection by 71x and backward projection by 137x. We generate these results with no perceptible difference in image quality between the GPU and serial CPU implementations. This work illustrates the power of using commercial off-the-shelf relatively low-cost GPUs, potentially allowing IRT tomographic image reconstruction to be run in near real time, lowering the barrier to entry of IRT, and enabling deployment in the clinic.

AB Here, we used both the neuromagnetic (MEG) and the hemodynamic (fMRI) measures to visualize the spatiotemporal brain dynamics during 3-D structure perception from 2D motion (3D-SFM). The coherence of the random-dot motion stimuli was parametrically controlled to infer the changes of the brain dynamics corresponding to different 3-D percepts. The results of the fMRI analysis were used to impose plausible constraints on the MEG inverse calculation using the 'weighted' minimum-norm approach to improve spatial resolution of the spatiotemporal activity estimates. The inferior-temporal, the parieto-occipital, and the intraparietal regions showed increased neural activity in the highly coherent motion conditions in which subjects perceived robust 3-D object structure at different latencies. These results are in agreement with the previous fMRI studies and add further insight into the temporal dynamics of the neural activities in the multiple brain regions along both the dorsal and the ventral visual processing streams during 3D-SFM.

ID QUALITY; SCANNER
AB Cardiac imaging represents one of the most challenging imaging problems, requiring high spatial and temporal resolutions along with good tissue contrast. One of the newest clinical cardiac CT scanners incorporates two source-detector pairs in order to improve the temporal resolution by two-fold. To achieve the highest spatial resolution, reconstructions using iterative techniques may be desired. Yet the complexity of the dual-source geometry makes accurate system modeling a challenge. In this paper, we present a model-based iterative reconstruction algorithm for the dual-source CT. We demonstrate, using a total variation formulation, the results of our reconstructions. To accelerate the processing and enhance the quality of the result, we also incorporate a simplified detector response function in the forward projector. A segment of heavily-calcified coronary artery is used to demonstrate the spatial and temporal

AB We present results of diffused phosphorescence lifetime tomography performed on tissue-simulating phantoms for high contrast imaging of hypoxic breast tumors. Oxygen sensitive phosphor embedded in a versatile nanoparticle matrix was used as contrast agent to identify simulated hypoxic tumors in phantoms. The surface of these nanoparticles was decorated with F3 peptide that targets cell surface receptors that is often overexpressed in aggressive breast tumors. The surface functionalization did not interfere with the embedded phosphor's characteristics. The phosphorescence intensity and lifetime was measured using single photon sensitive multi-pixel photon counting (MPPC) detectors in box-car geometry. The detection technique has a large dynamic range, high sensitivity and good resolution in oxygen concentration.

AB Cathartic bowel preparation is a major barrier in implementing clinically feasible colorectal screening programs. We developed a fully automated computer-aided detection (CAD) scheme for a cathartic-free computed tomographic colonography (CTC) examination. In a pilot evaluation with 46 clinical cathartic-free CTC cases, the proposed scheme detected 100% (4/4) of large >= 10 mm lesions with 3.7 false-positive (FP) detections per patient (per two volumetric CT scans) and 90% (9/10) of >= 6 mm lesions with 5.0 FP detections per patient, on average. The results indicate that CAD can be used to detect clinically significant lesions with high accuracy in cathartic-free CTC examinations.

AB Coronary artery disease (CAD) or atherosclerosis is a leading cause of death in industrialized nations. Such diseases are marked by development of chronic vascular inflammation in coronary arteries. Accurate assessment, characterization and localization of this inflammation through non-invasive methods is an important Step towards the treatment of CAD. It has been shown that positron emission tomography (PET) is capable of detecting large vessel inflammation via activated macrophage uptake of FDG. However, respiratory and cardiac motion during image acquisition leads to severe blurring of the resulting images thereby rendering the spatial resolution inadequate for detection of inflammation in coronary arteries. The objective of this paper is to demonstrate the potential of producing high resolution PET images to enable imaging of coronary artery inflammation.
In this paper, we propose a novel method for joint cardiac and respiratory motion correction in PET/CT called Cardiac Shape Tracking with Adjustment for Respiration (CSTAR). It uses a sequential cardiac and respiratory motion correction scheme by decoupling the two, and also features the use of all acquired data for SNR preservation. CT images are primarily used for cardiac shape tracking through the estimation of cardiac motion. Cardiac motion correction is incorporated in a super-resolution framework, followed by adjustment for the residual respiratory motion blur using blind deconvolution. We investigated the feasibility of this technique on simulated cardiac PET/CT data using XCAT and the preliminary results show a marked qualitative and quantitative improvement when compared to conventional PET reconstruction.

AB The objective of this work is to validate a fast and reliable 4D-based adaptive treatment planning procedure for the Radiation Oncology clinic. A non-rigid B-Spline based registration is per-formed between CT scans at different respiratory phases. Radiotherapy contours drawn on a reference phase are than propagated to the target phase. We present results from two novel validation methods: a validation study using a 4D anthropomorphic computational phantom, and a patient data analysis comparing auto-rater versus inter-rater variability. For the phantom study, the overlap was greater than 90%, while the diameter variation was 5.1% at exhale and 3.4% at inhale. For the patient dataset, pairwise auto-rater Dice coefficient values exceeded inter-rater values for 9 of 15 structures. Though subject to inaccuracies caused by residual motion artifacts, and manual contouring variations, the reliability of the method suggests it could be soon introduced in the clinical practice.

This toolbox incorporates a number of existing free mesh processing utilities and enables researchers to perform a range of mesh processing tasks for image-based mesh generation, including raw image processing, surface mesh extraction, surface re-sampling, and multi-scale/adaptive tetrahedral mesh generation. We also implemented robust algorithms for meshing open-surfaces and sub-region labeling. Atomic meshing utilities for each processing step can be accessed with simple interfaces, which can be streamlined or executed independently. The toolbox is compatible with Matlab or GNU Octave. We demonstrate the applications of this toolbox for meshing a range of challenging geometries including complex vessel network, human brain and breast.

ID FLOW
AB Anatomical imaging modalities such as MR and CT produce high resolution images that are essential in modern health care. Anatomical imaging, however, can be supplemented with functional imaging to provide additional insights into the status and progression of disease. In perfusion imaging, a bolus of contrast entering a tissue region of interest is carefully monitored in order to derive hemodynamic parameters. While useful, perfusion parameter maps tend to be noisy, in part because the parameters of every voxel are computed independently of its neighboring voxels. A spatio-temporally correlated approach to estimating perfusion parameters has been previously introduced. In this paper, we expand upon this earlier formulation and demonstrate its functionality on a set of rectal tumor patients undergoing CT perfusion (CTp) studies. Our results show that our spatio-temporal deconvolution approach is less noisy than conventional singular value deconvolution approach, and show greater separation between normal and cancerous regions.

AB MHC (Major Histocompatibility Complex) is a key player in the immune response of an organism. It is important to be able to predict which antigenic peptides will bind to a specific MHC allele and which will not, creating possibilities for controlling immune response and for the applications of immunotherapy. however, a problem for MHC class I is the presence of bulges and loops in the peptides, changing the total length. Most machine learning methods in use today require the sequences to be of same length to successfully mine the binding motifs. We propose the use of time-based data mining methods in motif mining to be able to mine motifs position-independently. Also, the information for both binding and nonbinding peptides is used on the contrary to the other methods which only rely on binding peptides. The prediction results are between 60-95% for the tested alleles.

AB This paper introduces a compact, wireless, wearable system that measures signals indicative of forces, torques and other descriptive and evaluative features that the human body undergoes during bursts of extreme physical activity (such as during athletic performance). Standard approaches leverage highspeed camera systems, which need significant infrastructure and provide limited update rates and dynamic accuracy. This project uses 6 degree-of-freedom inertial measurement units worn on various segments of an athlete's body to directly make these dynamic measurements. A combination of low and high range sensors enables sensitivity for both slow and fast motion, and the addition of a compass helps in tracking joint angles. Data from the battery-powered nodes is acquired using a custom wireless protocol over an RF link and analyzed offline. Several professional pitchers and batters were instrumented with the system and data was gathered over many pitches and swings. We show some biomechanically descriptive parameters extracted from this data, and highlight ongoing work and system improvements.

ID VASCULOGENESIS; ANGIOGENESIS
AB Angiogenesis in the embryonic brain was long considered to be a passive process principally occurring in response to metabolic demands placed growing neuronal populations. The brain vasculature develops concomitant with neuronal development, which is regulated by compartment-specific cell autonomous factors. Yet, cell autonomous patterning signals were not considered to regulate brain angiogenesis. We show that angiogenesis in the mouse telencephalon occurs in an orderly, ventral-to-dorsal gradient regulated cell-autonomously by compartment-specific homeo-box transcription factors. These transcription factors also regulate compartmental identities of telencephalic neurons and progenitor populations. Thus, our data offer now perspectives on neurovascular interactions and compartmental identities in the embryonic telencephalon.

AB Effective mentorship is likely one of the most important determinants of success in academic medicine and research. Many papers focus on mentoring from the mentor's perspective, but few give guidance to mentees forging these critically important relationships. The authors apply "managing up," a corporate concept, to academic medical settings both to promote effective, successful mentoring and to make a mentor's job easier. Managing up requires the mentee to take responsibility for his or her part in the collaborative alliance and to be the leader of the relationship by guiding and facilitating the mentor's efforts to create a satisfying and productive relationship for both parties. The authors review the initiation and cultivation of a mentoring relationship from the perspective of a mentee at any stage (student through junior faculty), and they propose specific strategies for mentee success.

ID CHILDRENS HEALTH-CARE; QUALITY; CONTINUITY; ACCESS
AB Objective.-To assess parental experience of pediatric primary care at the level of physician practice and to determine what variation exists among practices.
Methods.-This cross-sectional survey assessed 7 pediatric primary care practices in eastern Massachusetts. Parents of children aged <= 12 years who received care between July 1999 and June 2000 were surveyed. Parents assessed practice performance in 6 areas of quality: access to care, patient education and information, patient/physician relationship, coordination and Continuity of care, office Staff Courtesy and helpfulness. and specialty care experience.
Results.-Surveys were returned by 744 parents (response rate 50%). Practices performed best in the domains of patient education and access to care, and performed poorest in coordination/continuity and specialty care experience. Practice performance varied in the included domains, with significant interpractice variation in specialty care experience (range 61-83 on 100-point scale), coordination and continuity (range 64-84), and access to care (range 80-92). Items with significant variation included the physician/nurse being informed about specialist care, file physician/nurse knowing the parent/child as people, staff helpfulness, and the physician/nurse knowing what worried the parent about the child's health.
Conclusions.-Parent reports of specific experiences of care revealed priorities for improvement in several areas. including coordination and continuity. specialty care experience, and interpersonal aspects of care. Performance differed among practices, providing an Opportunity for practices to learn from each other. survey-based measures of quality can help identify variation in performance and Priorities for improving quality of care.

DT Article
ID DISCLOSURE
AB Objective: The authors discuss journal writing in learning emergency psychiatry.
Methods: The journal of a psychiatry intern rotating through an emergency department is used as sample material for analysis that could take place in supervision or a resident support group. A range of articles are reviewed that illuminate the relevance of journal writing for the learning process, including articles about resident resilience, "autognosis," the learning process in psychiatry, and " limbic music."
Results: Journal writing is a useful tool in consolidating knowledge, and can be used along with traditional exercises for learning psychiatry such as writing chart notes, process notes, and completing required studies for examinations.
Conclusion: Psychiatry training should continue to explore the use of journals as residents continue to write them.

ID POSITION STATEMENT; ABUSE; EDUCATION
AB Objective: The authors describe an addiction psychiatry curriculum integrated in a general psychiatry training program to demonstrate comprehensive and practical approaches to educating general psychiatric residents on the recognition and treatment of substance use disorders.
Methods: The Massachusetts General Hospital/McLean Hospital adult psychiatric residency training program provides training in addiction psychiatry in multiple treatment settings during the 4 years of residency. Addiction specialists, nonspecialty psychiatrists, and residents and fellows provide training.
Results: Adult psychiatric residencies can provide comprehensive addiction psychiatry training that spans multiple treatment settings and postgraduate years by training general staff psychiatrists, senior residents, and fellows to assist core addiction faculty in providing addiction psychiatry education.
Conclusion: Substance use disorders are common among patients presenting to general psychiatry treatment settings, and thus it is important that all psychiatric residents be well trained in the screening, diagnosis, and treatment of outpatients with these problems.

AB Rationale and Objectives. The authors present their initial experience using a 3-T whole-body scanner equipped with a 128-channel coil applied to lung motion assessment. Recent improvements in fast magnetic resonance imaging (MRI) technology have enabled several trials of free-breathing three-dimensional (313) imaging of the lung. A large number of image frames necessarily increases the difficulty of image analysis and therefore warrants automatic image processing. However, the intensity homogeneities of images of prior dynamic 3D lung MRI studies have been insufficient to use such methods. In this study, initial data were obtained at 3 T with a 128-channel coil that demonstrate the feasibility of acquiring multiple sets of 3D pulmonary scans during free breathing and that have sufficient quality to be amenable to automatic segmentation.
Materials and Methods. Dynamic 3D images of the lungs of two Volunteers were acquired with acquisition times of 0.62 to 0.76 frames/s and an image matrix of 128 X 128, with 24 to 30 slice encodings. The volunteers were instructed to take shallow and deep breaths during the scans. The variation Of lung volume was measured from the segmented images.
Results. Dynamic 3D images were successfully acquired for both respiratory conditions for each subject. The images showed whole-lung motion, including lifting of the chest wall and the displacement of the diaphragm, with sufficient contrast to distinguish these structures from adjacent tissues. The average time to complete segmentation for one 3D image was 4.8 seconds. The tidal volume measured was consistent with known tidal volumes for healthy subjects performing deep-breathing maneuvers. The temporal resolution was insufficient to measure tidal volumes for shallow breathing
Conclusion. This initial experience with a 3-T whole-body scanner and a 128-channel coil showed that the scanner and imaging protocol provided dynamic 3D images with spatial and temporal resolution sufficient to delineate the diaphragmatic domes and chest wall during active breathing. In addition, the intensity homogeneities and signal-to-noise ratio were adequate to perform automatic segmentation.

AB Objective. To investigate whether survival rates published in the EUROCARE studies for Tyrol are distorted, we evaluated data quality in the Cancer Registry of Tyrol. Material and methods. Potential errors in completeness of Tyrolean incidence data were assessed by applying semi-quantitative and quantitative methods, in part by comparing indices for Tyrol with those of neighboring countries published in Cancer Incidence in Five Continents. Validity of patient survival status was checked for all cancer patients diagnosed in 1997 (n = 2 556). For all 1 026 of these patients still alive at end of 2007, we reassessed survival status. Finally, we re-abstracted date of diagnosis for a subset of 295 patients. Results. Quality indices on completeness showed no greater bias with the exception of borderline ovarian cancer, which was in part miscoded in the early nineties. Some differences for bladder cancer and prostate cancer between Tyrol and neighboring countries are due to PSA testing and pathology diagnosis. Concerning patient survival status, four cases were erroneously assessed as alive, five cases died outside Austria, three cases were proven not to belong to the population of Tyrol at time of diagnosis and 21 cases emigrated. Absolute errors in survival rates were less than 0.5 for up to five-year survival rates and less than 1.0 for ten year survival rates. Conclusions. Evaluation of data quality in the Cancer Registry of Tyrol demonstrated that the survival rates published for Tyrol are only minimally biased by registration or analysis procedures. However, access to data on emigration, which until now is not possible because of data protection restrictions, would reduce the bias in patient survival status, bearing in mind that the extent of emigration of cancer patients is expected to increase in Austria over the coming years.

AB Objective: We performed a longitudinal study of holocaust survivors with and without post-traumatic stress disorder ( PTSD) by assessing symptoms and other measures at two intervals, approximately 10 years apart.
Method: The original cohort consisted of 63 community-dwelling subjects, of whom 40 were available for follow-up.
Results: There was a general diminution in PTSD symptom severity over time. However, in 10% of the subjects (n = 4), new instances of delayed onset PTSD developed between time 1 and time 2. Self-report ratings at both assessments revealed a worsening of trauma-related symptoms over time in persons without PTSD at time 1, but an improvement in those with PTSD at time 1.
Conclusion: The findings suggest that a nuanced characterization of PTSD trajectory over time is more reflective of PTSD symptomatology than simple diagnostic status at one time. The possibility of delayed onset trajectory complicates any simplistic overall trajectory summarizing the longitudinal course of PTSD.

AB Gastrointestinal stromal tumors (GISTs) account for the majority of gastrointestinal mesenchymal tumors. Recent advances in treatment using the molecular targeting agent imatinib mesylate have shown startling response rates and variegated imaging findings. We present the various imaging appearances of GIST on computed tomography (CT) and magnetic resonance imaging (MRI), both before and after treatment.

AB In this article, we discuss the hypothesis that affect is a fundamental, psychologically irreducible property of the human mind. We begin by presenting historical perspectives on the nature of affect. Next, we proceed with a more contemporary discussion of core affect as a basic property of the mind that is realized within a broadly distributed neuronal workspace. We then present the affective circumplex, a mathematical formalization for representing core affective states, and show that this model can be used to represent individual differences in core affective feelings that are linked to meaningful variation in emotional experience. Finally, we conclude by suggesting that core affect has psychological consequences that reach beyond the boundaries of emotion, to influence learning and consciousness.

AB Members of the Runx family of transcription factors, Runx1-3, are essential regulators of the immune system: a deficiency in one of the members, Runx1, results in complete ablation of hematopoiesis, and all three Runx proteins play important, nonredundant roles in immune system development and function. Here, we review gene regulation by Runx proteins in T lymphocytes, with a focus on their recently emerging roles in the development and function of peripheral CD4(+) and CD8(+) T lineages.

AB The human immunodeficiency virus (HIV) epidemic provides a rare opportunity to examine in detail the initial stages of a host-pathogen co-evolutionary struggle in humans. The genes encoding the human leukocyte antigen (HLA) class I molecules have a critical influence in the success or failure of the immune response against HIV. The particular HLA class I molecules expressed by each individual defines the type of cytotoxic T-lymphocyte (CTL) response that is made against the virus. This chapter describes the role of HLA class I and the CTL response in controlling HIV replication, and discusses the extent to which HIV has already adapted to those HLA class I molecules and CTL responses that are most effective in viral suppression. It is evident that viral mutations that enable HIV to evade the CTL response are indeed already accumulating in populations where the selecting HLA molecules are highly prevalent, indicating the dynamic and shifting nature of the evolutionary interplay between HIV and human populations.

WOMEN; PHARMACOKINETICS; CONSUMPTION; FREQUENCY; LIPIDS; SERUM; EQUOL
AB Background: a small number of reports exist on the cognitive effects of soy isoflavones, the findings from which are mixed. Isoflavone efficacy is dependent upon conversion of glycosides contained in soy foods and supplements to the biologically active aglycons. Of particular interest is the production of the metabolite, equol, which is dependent upon intestinal microflora and an integrous digestive system, both being altered by age and age-associated conditions. Unfortunately, few studies enrolled adults over the age of 70, and none included older men.
Objective: we examined safety, feasibility and cognitive efficacy of soy isoflavone administration in older nondemented men and women (age 62-89 years).
Design and Methods: in this randomised, placebo-controlled, double-blind pilot study, subjects ingested either 100 mg/day soy isoflavones (glycoside weight) or matching placebo tablets for 6 months.
Results: active and placebo-treated subjects exhibited a comparable side-effect profile. Plasma levels of genistein and daidzein (P < 0.001), but not equol, increased with isoflavone administration. While similar at baseline, the two groups differed across 6 months of treatment on 8 of 11 cognitive tests administered. Isoflavone-treated subjects improved on tests of visual-spatial memory (P < 0.01) and construction (P = 0.01), verbal fluency (P < 0.01) and speeded dexterity (P = 0.04). Placebo-treated participants were faster than isoflavone-treated subjects on two tests of executive function (P < 0.05).
Conclusions: these data suggest that administration of 100 mg/day of isoflavones was well tolerated. Plasma genistein and daidzein levels, but not equol, increased with isoflavone administration. Finally, data support the potential cognitive effects of soy isoflavones in older adults.

AB Intimate partner violence (IPV) is a significant public health concern that affects an alarmingly high percentage of women. There is evidence to Suggest that African American women are impacted by IPV at higher rates than are Caucasian women, yet little of the IPV literature addresses the cultural and structural factors that differentially affect African American and Caucasian couples. The present paper reviews the existing literature on IPV towards African American women, including prevalence, theories, risk factors for victimization, victims' psychological sequelae, barriers to service utilization. coping strategies. and interventions for survivors and perpetrators of IPV. Recommendations for counseling, research, and policy are explored. Published by Elsevier Ltd.

AB Objectives: This study collected data on demographic factors, heart failure physical limitations, perception of heart failure intrusiveness, coping mechanisms, locus of control, self-efficacy and social support for 104 older veterans with heart failure (HF) to determine the factors' relative importance in predicting depressive symptoms. Method: Participants were veterans at least 60 years of age with HF who were screened for depression and anxiety with the Geriatric Depression Scale and Geriatric Anxiety Inventory, respectively, so that the final sample consisted of equal numbers with and without significant levels of anxiety and depression. Other measures included the Kansas City Cardiomyopathy Questionnaire, Heart Failure Illness Intrusiveness Rating Scale, Brief-COPE, Multidimensional Health Locus of Control Scale, Chronic Disease Self-Efficacy and Multidimensional Scale of Perceived Social Support. Results: Correlational analyses indicated that depressive symptoms were significantly associated with physical limitations from HF, HF perceptions of intrusiveness, maladaptive coping, attributing locus of control to chance and HF self-efficacy. Including these variables in one regression equation predicting depressive symptoms indicated that perceptions of intrusiveness from HF and attributing locus of control to chance were the only variables to predict depressive symptoms independent of the influence of other significant bivariate predictors. Conclusion: Even if physical limitations, maladaptive coping and self-efficacy are held constant, decreasing perceptions of HF intrusiveness and locus of control to chance reduce depressive symptoms. These two cognitive/perceptual factors may play a salient role in treatment of depression among older HF patients.

AB The female reproductive axis is the first major organ system of the body to fail with advancing age. In addition to a permanent cessation of fertile potential, the loss of cyclic ovarian function in humans heralds the onset of menopause, which in turn underlies the emergence of a diverse spectrum of health issues in aging women. Recently, it was reported that bone marrow (BM) transplantation (BMT) into adult female mice conditioned a week earlier with highly cytotoxic drugs rescues ovarian function and fertility. Herein we show in mice receiving no prior conditioning regimen that once monthly infusions of BM-derived cells retrieved from young adult female donors bearing an enhanced green fluorescent protein (EGFP) transgene sustain the fertile potential of aging wild-type females long past their time of normal reproductive senescence. The fertility-promoting effects of female donor BM are observed regardless whether the infusions are initiated in young adult or middle-aged females. Although the mechanism by which BM infusions benefit the reproductive performance of aging females remains to be elucidated, the absence of EGFP-expressing offspring suggests that it does not depend on development of mature eggs derived from germline-committed cells in the donor marrow. However, donor BM-derived somatic cells accumulate in the recipients, indicating efficient donor cell engraftment without prior conditioning. These findings provide a strong impetus to further explore development of adult stem cell-based technologies to safely extend function of the female reproductive axis into advanced age without the need for toxic preconditioning protocols routinely used in other models of stem cell delivery.

AB The US Centers for Disease Control and Prevention recommends the expanded use of rapid HIV antibody tests in community settings to increase the proportion of persons who are aware of their HIV status. The cost of providing rapid testing services in these settings is not known. We conducted a cost survey of non-profit community clinics and community-based organizations (CBOs). The final study sample for the cost analyses included 28 community clinics and seven CBOs that offered rapid HIV testing, all of which used OraSure's OraQuick oral fluid assay. Overall, the mean per-client rapid testing cost was $36.68 for HIV-negative clients (2006 dollars, provider perspective) and $44.22 for preliminary-positive clients. Personnel costs accounted for 55.6% of overall testing costs for negative clients and 63.2% for preliminary-positive clients. This study contributes unique empirical data about the costs of OralQuick rapid testing that can be used by clinic and CBO directors to assess the economic impact of implementing rapid testing at their sites. The findings also could be used to inform discussions regarding national and local HIV testing policies.

AB The present study assessed the presence of post-traumatic stress disorder (PTSD) symptoms in response to stressful or traumatic life events and their impact on HIV risk behaviors and associated psychosocial variables among men who have sex with men (MSM). Participants (n = 189; 60% HIV-infected) who were recruited by notices posted in a community health clinic and via a modified respondent-driven sampling technique completed a behavioral assessment survey. Sixty percentage of participants screened positive for having PTSD symptoms using the startle, physiological arousal, anger, and numbness screening instrument. After controlling for race, sexual self-identification, and HIV status, multivariable logistic regression analyses revealed that screening in for having PTSD symptoms was significantly associated with having engaged in unprotected anal (insertive or receptive) sex in the past 12 months, over and above any effects of whether or not a traumatic/stressful event occurred during the year (adjusted odds ratio [OR] = 2.72; p < 0.02; 95% confidence interval [CI] = 1.19-6.20). In addition, MSM with PTSD symptoms were more likely to have clinically significant depressive symptoms (adjusted OR = 3.50; p < 0.001) and/or symptoms of social anxiety (adjusted OR = 2.87; p < 0.01; 95% CI = 1.48-5.62). The current study, in the context of other research documenting the high rates of co-occurring psychosocial issues facing MSM, points to the importance of incorporating coping with these issues in HIV and sexually transmitted disease prevention and care interventions.

AB Several reports have suggested an increased prevalence of osteopenia and osteoporosis in HIV-infected individuals. Vitamin D deficiency may be a risk factor for osteoporosis and bone fractures. We aimed to determine the prevalence of vitamin D insufficiency in an outpatient HIV clinic in Boston. We collected serum levels of 25-OH vitamin D and evaluated calcium and vitamin D intake in adult HIV-positive outpatients during the winter and spring of 2005. Fifty-seven subjects were enrolled. The prevalence of moderate (<= 20 and >10 ng/ml) and severe (<= 10 ng/ml) 25-OH vitamin D deficiency was 36.8% and 10.5%, respectively. Lower vitamin D intake was significantly associated with severe 25-OH vitamin D deficiency (p = 0.01). Lactose intolerance tended to be associated with severe vitamin D deficiency (p = 0.08). Antiretroviral use and low daily calcium intake were significantly associated with elevated parathyroid hormone levels (p = 0.01 and 0.03, respectively). Vitamin D deficiency was frequent in ambulatory HIV-positive patients. HIV-infected individuals living in areas with low exposure to ultraviolet light during winter may benefit from vitamin D supplementation.

AB Background The burden of functional GI disorders and their associations with psychological distress in women veterans is unclear.
Aim To examine 1-year prevalence of irritable bowel syndrome (IBS) and dyspepsia symptoms and their associations with anxiety, depression and post-traumatic stress disorder (PTSD) among women veterans receiving primary care at a Veteran Affairs Medical Center Women's Clinic.
Methods Irritable bowel syndrome, dyspepsia and psychological distress were assessed using the validated self-administered Bowel Disorder Questionnaire, the Beck Depression and Anxiety Inventories, as well as the Mississippi Scale for Combat-Related Post-Traumatic Stress Disorder Questionnaire.
Results We enrolled 248 women (84% participation rate). Ninety-three (38%) reported IBS and 51 (21%) dyspepsia symptoms. Women with IBS and dyspepsia reported higher mean scores of anxiety (IBS: 24 vs. 12, P < 0.0005 and dyspepsia: 26 vs. 12, P < 0.0005), depression (IBS: 22 vs. 11, P = 0.0005 and dyspepsia: 23 vs. 11, P < 0.0005) and PTSD (IBS: 87 vs. 69, P < 0.001 and dyspepsia: 86 vs. 69, P < 0.0005). Age-and ethnicity-adjusted logistic regression analyses showed a 3-to 46-fold increase in odds of IBS and dyspepsia among women with anxiety, depression or PTSD.
Conclusion Women veterans have high prevalence of IBS and dyspepsia symptoms, both of which are highly associated with presence of depression, anxiety and PTSD.

AB This article focuses specifically on angioedema. Chronic angiodema represents a wide range of diseases and call be categorized into several forms including hereditary, acquired, drug induced, and idiopathic. Hereditary and acquired angioedema are known to be a result of abnormalities in C1 inhibitor protein while the mechanism of drug-induced and idiopathic angiodema is less clear. Significant advances have been made in recent years with regard to diagnosis and management of these patients leading to a significant reduction in morbidity and mortality. Several novel therapies are in clinical trials and should be available in the United States within the next year. There is still a lot to learn about the pathophysiology, diagnosis, and treatment of patients with chronic angioedema. This review will hopefully provide more information to the readers who care for patients with these disorders and also stimulate further interest and research into the pathophysiology of these conditions.

AB The clinical application of the concept of patient autonomy has centered on the ability to deliberate and make treatment decisions (decisional autonomy) to the virtual exclusion of the capacity to execute the treatment plan (executive autonomy). However, the one-component concept of autonomy is problematic in the context of multiple chronic conditions. Adherence to complex treatments commonly breaks down when patients have functional, educational, and cognitive barriers that impair their capacity to plan, sequence, and carry out tasks associated with chronic care. The purpose of this article is to call for a two-component re-conceptualization of autonomy and to argue that the clinical assessment of capacity for patients with chronic conditions should be expanded to include both autonomous decision-making and autonomous execution of the agreed-upon treatment plan. We explain how the concept of autonomy should be expanded to include both decisional and executive autonomy, describe the biopsychosocial correlates of the two-component concept of autonomy, and recommend diagnostic and treatment strategies to support patients with deficits in executive autonomy.

TI Arterial Age as a Function of Coronary Artery Calcium (from the
Multi-Ethnic Study of Atherosclerosis [MESA])
SO AMERICAN JOURNAL OF CARDIOLOGY
LA English
DT Article
ID RISK-ASSESSMENT; CHOLESTEROL; PLAQUE; CT
AB It has been proposed that coronary artery calcium (CAC) can be used to estimate arterial age in adults. Supporting this concept is that chronologic age, as used in cardiovascular risk assessment, is a surrogate for atherosclerotic burden. This measure can provide patients with a more understandable version of their CAC scores (e.g., "You are 55 years old, but your arteries are more consistent with an arterial age of 65 years"). The aim of this study was to describe a method of calculating arterial age by equating estimated coronary heart disease (CHD) risk for observed age and CAC. Arterial age is then the risk equivalent of CAC. Data from the Multi-Ethnic Study of Atherosclerosis (MESA), a cohort study of 6,814 participants free of clinical cardiovascular disease and followed for an average of 4 years, were used. Estimated arterial age was obtained as a simple linear function of log-transformed CAC. In a model for incident CHD risk controlling for age and arterial age, only arterial age was significant, indicating that observed age does not provide additional information after controlling for arterial age. Framingham risk calculated using this arterial age was more predictive of short-term incident coronary events than Framingham risk on the basis of observed age (area under the receiver-operating characteristic curve 0.75 for Framingham risk on the basis of observed age and 0.79 using arterial age, p = 0.006). In conclusion, arterial age provides a convenient transformation of CAC from Agatston units to a scale more easily appreciated by patients and treating physicians. (C) 2009 Elsevier Inc.

ID CORONARY-ARTERY DISEASE; RISK-FACTORS; SERUM-LIPIDS; FOLLOW-UP;
ASSOCIATION; SENILIS
AB Corneal arcus is a lipid-rich deposit at the corneoscleral limbus that shares some similarities with the lipid deposition of atherosclerosis. Epidemiologic studies examining the association between corneal arcus and coronary artery disease (CAD) have yielded mixed results. This study was conducted to determine if corneal arcus is an independent risk factor for cardiovascular disease (CVD) and CAD. A prospective analysis was performed using Cox proportional-hazards regression models in the Framingham Heart Study Original Cohort and Offspring Cohort database. This cohort included 23,376 patient-examinations, during 3,890 (17%) of which corneal arcus was identified. Corneal arcus was a predictor of CVD, and CAD at 4 years (hazard ratios [HRs] 2.28 and 1.99, respectively) and 8 years (HRs 2.52 and 2.35, respectively) of follow-up (p <0.0001 for all). Corneal arcus was no longer predictive of either CVD or CAD, however, after adjustment for age and gender at 4 years (HRs 1.07 and 1.01, respectively) and 8 years (HRs 1.18 and 1.17, respectively) of follow-up (p >0.05 for all). In conclusion, corneal arcus predicted CVD and CAD in the community-based Framingham Heart Study cohort because of the strong association of corneal arcus with increasing age. To date, this is the largest and lengthiest population-based cohort study examining the direct association between corneal arcus and CVD and CAD. (C) 2009 Published by Elsevier Inc.

AB The Asian patient with Fitzpatrick skin types III-V is rarely highlighted in publications on cutaneous disorders or cutaneous laser surgery. However, with changing demographics, Asians will become all increasingly important group in this context. Although high melanin content confers better photoprotection, photodamage in the form of pigmentary disorders is common. Melasma, freckles, and lentigines are the epidermal disorders commonly seen, whilst nevus of Ota and acquired bilateral nevus of Ota-like macules are common dermal pigmentary disorders. Post-inflammatory hyperpigmentation (PIH) occurring, after cutaneous injury remains a hallmark of skin of color. With increasing use of lasers and light sources in Asians, prevention and management of PIH is of great research interest. Bleaching agents, chemical peels, intense Pulsed light (IPL) treatments, and fractional skin resurfacing have all been used with some Success for the management of melasma. Q-switched (QS) lasers are effective for the management of epidermal pigmentation but are associated with a high risk of PIH. Long-pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers and IPL Sources pose less of a PIH risk but require a greater number of treatment sessions. Dermal pigmentary disorders are better targeted by QS ruby QS alexandrite, and QS 1064-nm Nd:YAG lasers, but hyper- and hypopigmentation may Occur. Non-ablative skin rejuvenation using a combination approach with different lasers and light sources in conjunction with cooling devices allows different skin chromophores to be targeted and optimal results to be achieved, even in skin of color. Deep-tissue heating using radiofrequency and infra-red light Sources affects the deep dermis and achieves enhanced skin tightening, resulting in eyebrow elevation, rhytide reduction, and contouring of the lower face and jawline. For management of severe degrees of photoaging, fractional resurfacing is useful for wrinkle and pigment reduction. as well as acne scarring.
Acne, which is common in Asians, can be treated with topical and oral antibacterials, hormonal treatments, and isotretinoin. Infra-red diode lasers used with a low-fluence, multiple-pass approach have also been shown to be effective with few complications. Fractional skin resurfacing is very useful for improving the appearance of acne scarring. Hypertrophic and keloid scarring, another common condition seen in Asians, can be treated with the combined used of intralesional triamcinolone and fluorouracil, followed by pulsed-dye laser. Esthetic enhancement procedures such as botulinum toxin type A and Fillers are becoming increasingly popular. These are effective for rhytide improvement and facial or body contouring. We highlight the differences between Asian skin and other skin types and review conditions common in skin of color together with treatment strategies.

AB A U.S. Army soldier stationed in Iraq developed myriad pain problems after sustaining a high-level spinal cord injury (SCI) from a gunshot wound. These problems were negatively impacting his ability to participate fully in his physical rehabilitation and care. Ten sessions of self-hypnosis training were administered to the patient over a 5-week period to help him address these problems. Both the patient and his occupational therapist reported a substantial reduction in pain over the course of treatment, which allowed the patient to actively engage in his therapies. Six months post treatment, the patient reported continued use of the hypnosis strategies taught, which effectively reduced his experience of pain. This case study demonstrates the efficacy of hypnotic analgesia treatment for U.S. military veterans who are experiencing pain problems due to traumatic or combat-related SCIs.

GLUCOSE
AB Background: Hypertriglyceridemia is a risk factor for cardiovascular disease. Variation in the apolipoprotein A5 (APOA5) and glucokinase regulatory protein (GCKR) genes has been associated with fasting plasma triacylglycerol.
Objective: We investigated the combined effects of the GCKR rs780094C -> T, APOA5 -1131T -> C, and APOA5 56C -> G single nucleotide polymorphisms (SNPs) on fasting triacylglycerol in several independent populations and the response to a high-fat meal and fenofibrate interventions.
Design: We used a cross-sectional design to investigate the association with fasting triacylglycerol in 8 populations from America, Asia, and Europe (n = 7730 men and women) and 2 intervention studies in US whites (n = `1061) to examine postprandial triacylglycerol after a high-fat meal and the response to fenofibrate. We defined 3 combined genotype groups: 1) protective (homozygous for the wild-type allele for all 3 SNPs); 2) intermediate (any mixed genotype not included in groups 1 and 3); and 3) risk (carriers of the variant alleles at both genes).
Results: Subjects within the risk group had significantly higher fasting triacylglycerol and a higher prevalence of hypertriglyceridemia than did subjects in the protective group across all populations. Moreover, subjects in the risk group had a greater postprandial triacylglycerol response to a high-fat meal and greater fenofibrate-induced reduction of fasting triacylglycerol than did the other groups, especially among persons with hypertriglyceridemia. Subjects with the intermediate genotype had intermediate values (P for trend < 0.001).
Conclusions: SNPs in GCKR and APOA5 have an additive effect on both fasting and postprandial triacylglycerol and contribute to the interindividual variability in response to fenofibrate treatment. Am J Clin Nutr 2009;89:391-9. Clin Nutr 2009; 89: 391-9.

DT Article
DE Clinical trial; lofexidine; oral delivery; pharmacokinetics; urine
AB Objectives: The objective of this study was to investigate lofexidine urine and plasma pharmacokinetics using three different dosing regimens in opioid dependent subjects. To date, there have been no published studies on lofexidine appearance and excretion in urine of opioid dependent subjects. Methods: Subjects were stabilized with 100 mg morphine sulphate on days 3-8 of the study. The dosing regimens of lofexidine hydrochloride were .8 mg twice a day (BID), 1.2 mg BID, or .8 mg three times a day (TID) on days 9 through 16 of the study. Plasma and urine samples were collected at appropriate time points. Area under the concentration-time curve (AUC), maximum concentration in plasma (C(max)), time when maximum concentration was reached (T(max)) and fraction excreted unchanged in urine (Fe) were calculated. Results: The average half-life obtained from all profiles was 12.1 +/- 6.3 hr. Steady-state (SS) was reached by study day 15. The plasma pharmacokinetic parameters for 1.2 mg BID and .8 mg TID dosing regimens did not seem to be different at steady state (day 15). T(max) was not statistically significantly different across dosing regimens. Fe values ranged between .01% and 34% with high variability within the same dosing regimen. For the total dose of 2.4 mg/day the two dosing regimens that were evaluated, namely 1.2 mg BID and .8 mg TID, did not show a significant statistical difference in plasma and urine pharmacokinetic parameters. Conclusion: Although preliminary due to the limited number of subjects, these findings are the first to document lofexidine urine pharmacokinetics in opiate addicts using a highly sensitive liquid chromatography tandem mass spectrometric analysis.

AB Objectives: Cardiac multidetector computed tomography (CMCT) has potential to be used as a screening test for patients with acute chest pain, but several tools are already used to risk-stratify this population. Risk models exist that stratify need for intensive care (Goldman), short-term prognosis (Thrombolysis in Myocardial Infarction, TIMI), and 1-year events (Sanchis). We applied these cardiovascular risk models to candidates for CMCT and assessed sensitivity for prediction of in-hospital acute coronary syndrome (ACS). We hypothesized that none of the models would achieve a sensitivity of 90% or greater, thereby justifying use of CMCT in patients with acute chest pain.
Methods: We analyzed TIMI, Goldman, and Sanchis in 148 consecutive patients with chest pain, nondiagnostic electrocardiogram, and negative initial cardiac biomarkers who previously met inclusion and exclusion criteria for the Rule-Out Myocardial Infarction Using Coronary Artery Tomography Study. ACS was adjudicated, and risk scores were categorized based on established criteria. Risk score agreement was assessed with weighted kappa statistics.
Results: Overall, 17 (11%) of 148 patients had ACS. For all risk models, sensitivity was poor (range, 35%-53%), and 95% confidence intervals did not cross above 77%. Agreement to risk-classify patients was poor to moderate (weighted kappa range, 0.18-0.43). Patients categorized as "low risk" had nonzero rates of ACS using all 3 scoring models (range, 8%-9%).
Conclusions: Available risk scores had poor sensitivity to detect ACS in patients with acute chest pain. Because of the small number of patients in this data set, these findings require confirmation in larger studies. (C) 2009 Elsevier Inc. All rights reserved.

AB In adults, light to moderate alcohol consumption is associated with lower risks for heart disease, diabetes, and mortality. This study examined whether light to moderate alcohol use is also associated with lower risk of incident physical disability over two 5-year periods in 4,276 noninstitutionalized adults in the United States, aged 50 years or older, by using data from 3 waves of the National Health and Nutrition Examination Survey Epidemiologic Follow-up Study surveys from 1982 to 1992. Light/moderate drinking (< 15 drinks per week and < 5 per drinking day or 4 per drinking day for women) was associated with reduced risk for incident disability or death over 5 years, compared with abstention (adjusted odds ratio = 0.77; P = 0.008). Among survivors, light/moderate drinking was associated with lower risk for incident disability, compared with abstention (adjusted odds ratio = 0.75; P = 0.009). In stratified analyses, disability risk decreased with light/moderate drinking in a dose-dependent fashion in men and women with good or better self-reported health but not in men or women with fair or worse self-reported health. Alcohol consumption in moderation might reduce the risk of developing physical disability in older adults in good health but not in those in poor health.

AB OBJECTIVES: Pancreatic necrosis is a serious complication of acute pancreatitis. The identification of simple laboratory tests to detect subjects at risk of pancreatic necrosis may direct management and improve outcome. This study focuses on the association between routine laboratory tests and the development of pancreatic necrosis in patients with acute pancreatitis.
METHODS: In a cohort of 185 patients with acute pancreatitis prospectively enrolled in the Severity of Acute Pancreatitis Study, patients with contrast-enhanced computerized tomography performed were selected (n = 129). Serum hematocrit, creatinine, and urea nitrogen on admission and peak values within 48 h of admission were analyzed. The volume of intravenous fluid resuscitation was calculated for each patient.
RESULTS: Of 129 patients, 35 (27%) had evidence of pancreatic necrosis. Receiver operating characteristic curves for pancreatic necrosis revealed an area under the curve of 0.79 for admission hematocrit, 0.77 for peak creatinine, and 0.72 for peak urea nitrogen. Binary logistic regression yielded that all three tests were significantly associated with pancreatic necrosis (P < 0.0001), with the highest odds ratio, 34.5, for peak creatinine. The volume of intravenous fluid resuscitation was similar in patients with and without necrosis. Low admission hematocrit (= 44.8%) yielded a negative predictive value of 89%; elevated peak creatinine (> 1.8 mg/dl) within 48 h yielded a positive predictive value of 93%.
CONCLUSIONS: We confirm that a low admission hematocrit indicates a low risk of pancreatic necrosis (PNec) in patients with acute pancreatitis. In contrast, an increase in creatinine within the first 48 h is strongly associated with the development of PNec. This finding may have important clinical implications and warrants further investigation.

TI Substitutive Hospital at Home for Older Persons: Effects on Costs
SO AMERICAN JOURNAL OF MANAGED CARE
LA English
DT Article
ID RANDOMIZED CONTROLLED-TRIAL; MINIMIZATION ANALYSIS; EARLY DISCHARGE;
INPATIENT INTERVENTIONS; CARE; HEALTH; PROGRAM
AB Objective:To compare the cost of substitutive Hospital at Home care versus traditional inpatient care for older patients with community-acquired pneumonia, exacerbation of chronic obstructive pulmonary disease, exacerbation of congestive heart failure, or cellulitis.
Study Design: Prospective nonrandomized clinical trial involving 455 community-dwelling older patients in 3 Medicare managed care health systems and at a Department of Veterans Affairs medical center.
Methods: Costs were analyzed across all patients, within each of the separate health systems, and by condition. Generalized linear models controlling for confounders and using a log link and gamma family specification were used to make inferences about the statistical significance of cost differences. tTests were used to make inferences regarding differences in follow-up utilization.
Results: The costs of the Hospital at Home intervention were significantly lower than those of usual acute hospital care (mean [SD], $5081 [$4427] vs $7480 [$8113]; P<.001). Laboratory and procedure expenditures were lower across all study sites and at each site individually. There were minimal significant differences in health service utilization between the study groups during the 8 weeks after the index hospitalization. As-treated analysis results were consistent with Hospital at Home costs being lower.
Conclusions: Total costs seem to be lower when substitutive Hospital at Home care is available for patients with congestive heart failure or chronic obstructive pulmonary disease. This result may be related to the study-based requirement for continuous nursing input. Savings may be possible, particularly for care of conditions that typically use substantial laboratory tests and procedures in traditional acute settings.

AB Background/Aims: The aim of this study was to determine the decline in the estimated glomerular filtration rate (eGFR) in elderly persons and to compare estimates based on creatinine and cystatin C. Methods: In the Cardiovascular Health Study, GFR changes in an elderly cohort were estimated from serum creatinine and cystatin C measured at baseline, year 3 and year 7 in 4,380 participants (age 72 +/- 5 years at entry). Outcomes were mean eGFR decline, incident chronic kidney disease (CKD) and rapid decline in eGFR (annual loss >3 ml/min/1.73 m(2)). Results: Mean annual eGFR loss as estimated from creatinine was 0.4 +/- 3.6 ml/min/1.73 m(2), with 16% of the participants experiencing a rapid decline. Mean eGFR loss as estimated from cystatin C was 1.8 +/- 2.6, with 25% of the participants experiencing a rapid decline (p<0.001 for both). Among participants without baseline CKD, incident CKD was detected at year 7 in 10% (n=263) using creatinine and 19% (n=544) using cystatin C (p<0.001). Increasing age was the strongest predictor of rapid decline; adjusted odds ratios were 1.38 (1.16-1.65), 1.62 (1.31-1.99) and 2.96 (2.28-3.84) for participants aged 70-74, 75-79 and 80+ at baseline, compared with those aged 65-69. Conclusion: In elderly persons, cystatin C estimated substantially larger declines in kidney function than creatinine did. Defining the optimal measurement of kidney function in elderly persons should be a high priority for future research. Copyright (C) 2009 S. Karger AG, Basel

AB Background/Aims: Because the relation between glycemic control and clinical outcomes found in the general diabetic population has not been established in diabetic hemodialysis patients, we evaluated the association between glycemic control and hospitalization risk. Methods: We performed a primary retrospective data analysis on 23,829 hemodialysis patients with diabetes mellitus. Hemoglobin A(1c) at baseline and hospitalization events over the subsequent 12 months were analyzed and logistic regression models constructed for unadjusted, case mix-adjusted and case mix plus lab-adjusted data. Models were also constructed for cardiovascular, vascular access and sepsis hospitalizations. Results: Eighty percent had type 2DM, 5% type 1 and 14% not specified. The groups had similar mean HbA(1c) levels, 6.8 +/- 1.6%. Among all patients, the mean HbA(1c) values were > 7% in 35%. The odds ratio of hospitalizations grouped by baseline HbA(1c) was significant at extremes of < 5% and > 11%. Similar relationships were evident for the subset of type 2DM and in the analysis for hospitalizations due to sepsis. Conclusion: Extremely high and low HbA(1c) values are associated with hospitalization risk in diabetic hemodialysis patients. Prospective studies are needed to determine whether meeting recommended HbA(1c) targets might improve outcomes without posing additional risks in this population. Copyright (C) 2008 S.

AB Background: Prior studies evaluating the relationship of kidney disease with cardiovascular risk factors have been limited by their cross-sectional design. We evaluated the change in lipids, inflammatory and procoagulant biomarkers with decline in kidney function in a nested case-cohort study in the Cardiovascular Health Study, a community-based study of adults aged >65 years. Methods: Individuals with an increase in serum creatinine >= 0.3 mg/dl (baseline to 3 years later, n = 207) were matched to controls of similar age, race, gender, diabetes and baseline serum creatinine, but whose change in creatinine was <0.3 mg/dl. Baseline and change in risk factors were analyzed with conditional logistic regression. Results: Changes in C-reactive protein were similar. In contrast, cases had larger increases in fibrinogen (OR 1.38 per standard deviation, 95% confidence interval 1.08-1.76) and factor VIII [1.38 (1.10-1.72)] and larger decreases in HDL [OR 0.80 (0.64, 1.00)]. Change in interleukin-6 was greater in cases than controls, but this did not persist after multivariate adjustment. However, in linear regression, change in interleukin-6 was correlated with change in creatinine. Conclusion: Cardiovascular risk factors and kidney function may change concurrently. This could lead to an increased risk of cardiovascular disease as kidney function worsens. Copyright (C) 2008 S. Karger AG, Basel

ID RECOMBINANT-HUMAN-ERYTHROPOIETIN; STAGE RENAL-DISEASE; LEVEL
VARIABILITY; ANEMIA MANAGEMENT; MORTALITY; ASSOCIATIONS; ESRD
AB Background: Compared to the intravenous route, subcutaneous administration of epoetin requires lower dose and will be an attractive option for cost containment when bundling for dialysis is implemented. Hemoglobin variability defined as fluctuation of hemoglobin over time has not been well studied with respect to the route of administration. Methods: 157 prevalent-hemodialysis subjects were analyzed from an open-label, randomized study that compared the intravenous to the subcutaneous route of epoetin with identical weight-based dosing algorithm. Hemoglobin variability was defined as the number of weeks hemoglobin is outside the target range of 10-11 g/dl. Sensitivity analysis was performed. Results: 78 subjects in the intravenous and 79 in the subcutaneous group entered the 24-week dose maintenance phase. Baseline covariates were similar in both groups except for the dose of epoetin (lower in subcutaneous) and dialysis vintage (longer in intravenous). Patients on subcutaneous epoetin were outside the target range more weeks (p = 0.04) and had higher standard deviation of hemoglobin (p = 0.01) compared to the intravenous group. Conclusions: The subcutaneous route of epoetin was associated with modestly higher hemoglobin variability, probably reflecting greater sensitivity of the subcutaneous route and/or identical epoetin-dosing algorithm employed in both the arms.

AB Background: Recent studies suggest that expression of the transforming growth factor-beta (TGF-beta)-inducible gene-h3 (beta ig-h3) and its anti-lysosomal activity may be responsible for the development of albuminuria and cardiovascular disease associated with hypertension. Methods: We evaluated the proposed linkage using the spontaneously hypertensive rat (SHR) and Wistar-Kyoto rat models. The kidney and left ventricular weight/body weight ratios were measured and cardiac collagen deposition was analyzed by Masson's trichrome stain. Renal and cardiac TGF-beta(1) and beta ig-h3 expression were determined by real-time reverse transcription-polymerase chain reaction, and renal and cardiac cathepsin B and L activities were measured as an indicator of lysosomal proteolytic activity. Results: SHR exhibited increased levels of intact urinary albumin without significant change in total albumin (intact plus albumin-derived material) excretion. This was accompanied by renal hypertrophy, increased renal beta ig-h3 expression, and reduced renal cathepsin B and L activities. At the same time, increased cardiac TGF-beta(1) and beta ig-h3 expression and reduced cardiac cathepsin B activity was identified in SHR in addition to cardiac hypertrophy and increased collagen deposition. All these changes could be ameliorated with ramipril treatment. Conclusions: These findings implicate for the first time beta ig-h3 expression and lysosomal activity as a key factor in the induction of albuminuria and cardiovascular disease associated with hypertension.

AB Background: American Indians and Alaska Natives (AIAN) have a high incidence of end-stage renal disease. Less is known about chronic kidney disease (CKD) among AIAN and whether risk factors differ for low estimated glomerular filtration rate (eGFR) versus albuminuria with a normal eGFR. Methods: Cross-sectional study examining the associations of age, sex, smoking, obesity, diabetes, hypertension, family history, and geographic region with CKD among a screened population of AIAN participants in the Kidney Early Evaluation Program from 2000 to 2006. CKD was defined by the presence of either a low eGFR, < 60 ml/min/1.73 m(2), or albuminuria, a urine albumin/creatinine ratio >= 30 mg/g. Results: The prevalence of any CKD was 29%, of low eGFR was 17%, and of albuminuria with a normal eGFR was 12%. Older age was the strongest predictor of low eGFR (61+ years OR 8.42, 95% Cl 5.92-11.98), followed by hypertension (OR 2.38, 95% Cl 1.74-3.26). In contrast, diabetes (OR 2.04, 95% Cl 1.57-2.64) and hypertension (OR 2.63, 95% Cl 1.93-3.59) were the only predictors of albuminuria among persons with a normal eGFR. Conclusion: The burden of CKD was high among this screened population of AIAN, and different risk factor patterns were associated with low eGFR and albuminuria. Innovative programs and longitudinal research are needed to address CKD among AIAN. Copyright (c) 2008 S. Karger AG, Basel

TI Intra-Arterial Nicardipine Infusion Improves CT Perfusion-Measured
Cerebral Blood Flow in Patients with Subarachnoid Hemorrhage-induced
Vasospasm
SO AMERICAN JOURNAL OF NEURORADIOLOGY

ID COOPERATIVE ANEURYSM; RANDOMIZED-TRIAL; TOMOGRAPHY; NIMODIPINE;
PREVENTION; EXPERIENCE; MANAGEMENT; THERAPY
AB BACKGROUND AND PURPOSE: Our aim was to determine the effects of intra-arterial (IA) nicardipine infusion on the cerebral hemodynamics of patients with aneurysmal subarachnoid hemorrhage (aSAH)-induced vasospasm by using first-pass quantitative cine CT perfusion (CTP).
MATERIALS AND METHODS: Six patients post-aSAH with clinical and transcranial Doppler findings suggestive of vasospasm were evaluated by CT angiography and CTP immediately before angiography for possible vasospasm treatment, CTP was repeated immediately following IA nicardipine infusion. Maps of mean transit time (MITT), cerebral blood volume (CBV), and cerebral blood flow (CBF) were constructed and analyzed in a blinded manner. Corresponding regions of interest on these maps from the bilateral middle cerebral artery territories and, when appropriate, the bilateral anterior or posterior cerebral artery territories, were selected from the pre- and posttreatment scans. Normalized values were compared by repeated measures analysis of variance.
RESULTS: Angiographic vasospasm was confirmed in all patients. In 5 of the 6 patients, both CBF and MTT improved significantly in affected regions in response to nicardipine therapy (mean increase in CBF, 41 +/- 43%; range, -9%-162%, P = .0004; mean decrease in MTT, 26 +/- 24%; range, 0%-70%, P = .0002). In I patient, we were unable to quantify improvement in flow parameters due to section-selection differences between the pre- and posttreatment examinations.
CONCLUSIONS: IA nicardipine improves CBF and MTT in ischemic regions in patients with aSAH-induced vasospasm. Our data provide a tissue-level complement to the favorable effects of IA nicardipine reported on prior angiographic studies. CTP may provide a surrogate marker for monitoring the success of treatment strategies in patients with aSAH-induced vasospasm.

AB Objective: Psychomotor slowing is a common manifestation of traumatic brain injury. Previous electrophysiological studies of traumatic brain injury have focused on abnormal attentional and perceptual responses to incoming stimuli. We hypothesize that traumatic brain injury is also associated with abnormal cortical components of motor execution.
Design: To test this hypothesis, we analyzed event-related potentials of 22 subjects (11 with a history of severe traumatic brain injury and 11 age-matched healthy subjects) during oddball discrimination tasks. In addition to the usual stimulus-locked averaging of electrophysiological data to reveal cognitive components, such as the P300, we also analyzed subjects' response-locked data to reveal motor potential waveforms. To focus on generalized effects across modality, analyses were performed on composite measures from both auditory and visual event-related potentials.
Results: (1) Traumatic brain injury subjects had abnormal P300 responses (with reduced amplitude and prolonged latency) in both sensory modalities. (2) Traumatic brain injury subjects' motor potential waveforms showed significantly reduced amplitude in both sensory modalities. (3) Abnormalities in P300 latency, amplitude, and motor potential amplitude (effect sizes = 1.2-1.5 SID) were greater than behavioral slowing, as measured by reaction times (0.7 SD). (4) P300 latency and motor potential amplitude together accounted for much of the reaction time prolongation (r = 0.73).
Conclusions: This study demonstrates the value of concurrently analyzing stimulus-locked and response-locked event-related potential data to evaluate cortical components of perceptual and motor processing. The present findings indicate that patients with traumatic brain injury have impairments in both the perceptual interpretation of incoming stimuli and the execution of motor responses and that both abnormalities contribute to psychomotor slowing in patients with traumatic brain injury.

TI The Feasibility of Hypnotic Analgesia in Ameliorating Pain and Anxiety

SO AMERICAN JOURNAL OF PHYSICAL MEDICINE & REHABILITATION
LA English
DT Article
DE Electromyography (EMG); Hypnosis; Hypnotic Analgesia
ID HYPNOSIS; PERCEPTION; ABSORPTION; DISTRESS; OPENNESS; CANCER
AB Objective: Our hypothesis was that hypnotic analgesia reduces pain and anxiety during electromyography (EMG).
Design: We performed a prospective randomized, controlled clinical trial at outpatient electrodiagnostic clinics in teaching hospitals. Just before EMG, 26 subjects were randomized to one of three 20-min audio programs: education about EMG (EDU) (n = 8); hypnotic induction without analgesic suggestion (n = 10); or hypnotic induction with analgesic suggestion (n = 8). The blinded electromyographer provided a posthypnotic suggestion at the start of EMG. After EMG, subjects rated worst and average pain and anxiety using visual analog scales.
Results: Mean values for the EDU, hypnotic induction without analgesic suggestion, and hypnotic induction with analgesic suggestion groups were not significantly different (mean +/- SD): worst pain 67 +/- 25, 42 +/- 18, and 49 +/- 30; average pain 35 +/- 26, 27 +/- 14, and 25 +/- 22; and anxiety 44 +/- 41, 42 +/- 23, and 22 +/- 24. When hypnosis groups were merged (n = 18) and compared with the EDU condition (n = 8), average and worst pain and anxiety were less for the hypnosis group than EDU, but this was statistically significant only for worst pain (hypnosis, 46 +/- 24 vs. EDU, 67 +/- 35; P = 0.049) with a 31% average reduction.
Conclusions: A short hypnotic induction seems to reduce worst pain during electromyography.

AB To assess barriers to bone mineral density testing in individuals with chronic spinal cord injury, a cross-sectional study of 20 individuals with spinal cord injury was conducted with assessment of physical and logistical barriers to dual energy x-ray absorptiometry scanning. We identified several barriers, including scanner design and configuration in the scanning room that limited accessibility, increased typical scanning time, and made additional staff necessary. For dual energy x-ray absorptiometry to become a routine component of ongoing care in spinal cord injury medicine, we recommend the following changes: (1) install ceiling-mounted hydraulic lifts and grab bars to facilitate transfers in the scanning room; (2) increase staffing during scans; (3) increase time allotment for scans; (4) install the scanner in an adequately-sized room; and (5) partner with administrators and staff to raise awareness of access issues faced by individuals with spinal cord injury.

First published November 11, 2008; doi: 10.1152/ajpendo.90506.2008.-Obesity is a risk factor for development of insulin resistance, type 2 diabetes, cardiovascular disease, osteoarthritis, and some forms of cancer. Many of the adverse health consequences of excess fat deposition are caused by increased secretion of proinflammatory adipokines by adipose tissue. Reciprocal muscle-to-fat signaling factors, or myokines, are starting to be identified. Interleukin-15 (IL-15) is a cytokine that is highly expressed in muscle tissue and that, on the basis of cell culture experiments, has been proposed to act as a circulating myokine that inhibits adipose tissue deposition. To test this hypothesis in vivo, two lines of transgenic mice that overexpressed IL-15 mRNA and protein in skeletal muscle tissue were constructed. By substitution of the inefficient native IL-15 signal peptide with a more efficient signal peptide, one of the transgenic mouse lines also exhibited elevated secretion of IL-15 in the circulation. Overexpression of IL-15 in muscle tissue without secretion in the bloodstream resulted in no differences in body composition. Elevated circulating levels of IL-15 resulted in significant reductions in body fat and increased bone mineral content, without appreciably affecting lean body mass or levels of other cytokines. Elevated circulating levels of IL-15 also inhibited adiposity induced by consumption of a high-fat/high-energy diet in male, but not female, transgenic mice. Female mice with elevated serum IL-15 exhibited increased deposition of lean body mass on a low-fat/low-energy diet and a high-fat/high-energy diet. These findings indicate that muscle-derived circulating IL-15 can modulate adipose tissue deposition and support addition of IL-15 to the growing list of potential myokines that are increasingly being implicated in regulation of body composition.

AB Toll-like receptor signaling: a critical modulator of cell survival and ischemic injury in the heart. Am J Physiol Heart Circ Physiol 296: H1-H12, 2009. First published November 14, 2008; doi: 10.1152/ajpheart.00995.2008. - Toll-like receptors (TLRs) represent the first line of host defense against microbial infection and play a pivotal role in both innate and adaptive immunity. TLRs recognize invading pathogens through molecular pattern recognition, transduce signals via distinct intracellular pathways involving a unique set of adaptor proteins and kinases, and ultimately lead to the activation of transcription factors and inflammatory responses. Among 10 TLRs identified in humans, at least two exist in the heart, i.e., TLR2 and TLR4. In addition to the critical role of these in mediating cardiac dysfunction in septic conditions, emerging evidence suggests that the TLRs can also recognize endogenous ligands and may play an important role in modulating cardiomyocyte survival and in ischemic myocardial injury. In animal models of ischemia-reperfusion injury or in hypoxic cardiomyocytes in vitro, the administration of a sublethal dose of lipopolysaccharide, which signals through TLR4, reduces subsequent myocardial infarction, improves cardiac functions, and attenuates cardiomyocyte apoptosis. By contrast, a systemic deficiency of TLR2, TLR4, or myeloid differentiation primary-response gene 88, an adaptor critical for all TLR signaling, except TLR3, leads to an attenuated myocardial inflammation, a smaller infarction size, a better preserved ventricular function, and a reduced ventricular remodeling after ischemic injury. These loss-of-function studies suggest that both TLRs contribute to myocardial inflammation and ischemic injury in the heart although the exact contribution of cardiac (vs. circulatory cell) TLRs remains to be defined. These recent studies demonstrate an emerging role for TLRs as a critical modulator in both cell survival and tissue injury in the heart.

First published November 7, 2008; doi:10.1152/ajplung.00467.2007.-Severe infection with respiratory syncytial virus (RSV) in children can progress to respiratory distress and acute lung injury (ALI). Accumulating evidence suggests that mechanical ventilation (MV) is an important cofactor in the development of ALI by modulating the host immune responses to bacteria. This study investigates whether MV enhances the host response to pneumonia virus of mice (PVM), a mouse pneumovirus that has been used as a model for RSV infection in humans. BALB/c mice were inoculated intranasally with diluted clarified lung homogenates from mice infected with PVM strain J3666 or uninfected controls. Four days after inoculation, the mice were subjected to 4 h of MV (tidal volume, 10 ml/kg) or allowed to breathe spontaneously. When compared with that of mice inoculated with PVM only, the administration of MV to PVM-infected mice resulted in increased bronchoalveolar lavage fluid concentrations of the cytokines macrophage inflammatory protein (MIP)-2, MIP-1 alpha (CCL3), and IL-6; increased alveolar-capillary permeability to high molecular weight proteins; and increased caspase-3 activity in lung homogenates. We conclude that MV enhances the activation of inflammatory and caspase cell death pathways in response to pneumovirus infection. We speculate that MV potentially contributes to the development of lung injury in patients with RSV infection.

First published October 22, 2008; doi:10.1152/ajpregu.90725.2008.- The hormones insulin and leptin have been demonstrated to act in the central nervous system (CNS) as regulators of energy homeostasis at medial hypothalamic sites. In a previous review, we described new research demonstrating that, in addition to these direct homeostatic actions at the hypothalamus, CNS circuitry that subserves reward and motivation is also a direct and an indirect target for insulin and leptin action. Specifically, insulin and leptin can decrease food reward behaviors and modulate the function of neurotransmitter systems and neural circuitry that mediate food reward, i.e., midbrain dopamine and opioidergic pathways. Here we summarize new behavioral, systems, and cellular evidence in support of this hypothesis and in the context of research into the homeostatic roles of both hormones in the CNS. We discuss some current issues in the field that should provide additional insight into this hypothetical model. The understanding of neuroendocrine modulation of food reward, as well as food reward modulation by diet and obesity, may point to new directions for therapeutic approaches to overeating or eating disorders.

First published November 5, 2008; doi: 10.1152/ajprenal.90222.2008. Better characterization of the molecular mechanisms underlying glomerular cell proliferation may improve our understanding of the pathogenesis of glomerulonephritis and yield disease-specific markers. We used two-dimensional gel electrophoresis (2DE) and mass spectrometry (MS) to generate expression profiles of glomerular proteins in the course of anti-Thy-1 nephritis. Glomeruli were isolated from Wistar rats by sieving, and proteins were separated by 2DE. In preliminary studies using normal rats, we identified known glomerular proteins from microfilaments [tropomyosin (Tm)] and intermediate filaments (vimentin and lamin A), proteins involved in assembly (alpha-actinin-4, F-actin capping protein) and membrane cytoskeletal linking (ezrin), as well as several enzymes (protein disulfide isomerase, ATP synthase, and aldehyde dehydrogenase). Comparison of glomerular protein abundance between normal rats and rats in the early phase of anti-Thy-1 nephritis yielded 28 differentially expressed protein spots. MS analysis identified 16 differentially expressed proteins including Tm. Altered Tm abundance in the course of anti-Thy-1 nephritis was confirmed, and specific isoforms were characterized by Western blotting. We demonstrated a complex change in Tm isoform abundance in the course of anti-Thy-1 nephritis. The early mesangiolytic phase of the disease was characterized by decreased abundance of low-molecular-weight isoforms Tm5a/5b and increased abundance of high-molecular-weight isoforms Tm6, Tm1, Tm2, and Tm3. The late proliferative phase of the disease was associated with increased abundance of isoforms Tm5a/5b, Tm6, and Tm1 and decreased abundance of Tm3. Isoforms Tm4 and Tm5 remained unchanged in the course of this model of experimental glomerulonephritis. Characterization of Tm isoform abundance in the course of clinical glomerulonephritis may identify disease-specific markers.

First published October 22, 2008; doi: 10.1152/ajprenal.90509.2008.-The primary cilium of renal epithelial cells is a nonmotile sensory organelle, implicated in mechanosensory transduction signals. Recent studies from our laboratory indicate that renal epithelial primary cilia display abundant channel activity; however, the presence and functional role of specific membrane receptors in this organelle are heretofore unknown. Here, we determined a functional signaling pathway associated with the type 2 vasopressin receptor (V2R) in primary cilia of renal epithelial cells. Besides their normal localization on basolateral membrane, V2R was expressed in primary cilia of LLC-PK(1) renal epithelial cells. The presence of V2R in primary cilia was determined by spontaneous fluorescence of a V2R-gfp chimera and confirmed by immunocytochemical analysis of wild-type LLC-PK(1) cells stained with anti-V2R antibodies and in LLC-PK(1) cells overexpressing the V2R-Flag, with anti-Flag antibody. Ciliary V2R colocalized with adenylyl cyclase (AC) type V/VI in all cell types tested. Functional coupling of the receptors with AC was confirmed by measurement of cAMP production in isolated cilia and by testing AVP-induced cation-selective channel activity either in reconstituted lipid bilayers or subjected to membrane-attached patch clamping. Addition of either 10 mu M AVP (trans) or forskolin (cis) in the presence but not the absence of ATP (1 mM, cis) stimulated cation-selective channel activity in ciliary membranes. This channel activity was reduced by addition of the PKA inhibitor PKI. The data provide the first demonstration for the presence of V2R in primary cilia of renal epithelial cells, and a functional cAMP-signaling pathway, which targets ciliary channel function and may help control the sensory function of the primary cilium.

SEPTEMBER 11; CRITERION-A; PTSD; TRAUMA; INTRUSION; EPIDEMIOLOGY
AB Unlike most psychiatric diagnoses, post-traumatic stress disorder (PTSD) is defined in relation to a potentially etiologic event (the traumatic "stressor criterion") that is fundamental to its conceptualization. The diagnosis of PTSD thus inherently depends on two separate but confounded processes: exposure to trauma and development of a specific pattern of symptoms that appear following the trauma. Attempts to define the range of trauma exposure inherent in the diagnosis of PTSD have generated controversy, as reflected in successive revisions of the criterion from DSM-III onward. It is still not established whether or not there are specific types of traumatic events and levels of exposure to them that are associated with a syndrome that is cohesive in clinical characteristics, biological correlates, familial patterns, and longitudinal diagnostic stability. On the other hand, the symptomatic description of PTSD is becoming more clear. Of three categories of symptoms associated with PTSD-intrusive memories, avoidance and numbing, and hyperarousal-avoidance and numbing appear to be the most specific for identification of PTSD. Research is now poised to answer questions about the relevance of traumatic events based on their relationship to symptomatic outcome. The authors recommend that future research begin with existing diagnostic criteria, testing and further refining them in accordance with the classic Robins and Guze strategy for validation of psychiatric diagnoses. In this process, diligent adherence to the criteria under examination is paramount to successful PTSD research, and changes in criteria are driven by empirical data rather than theory. Collaborations among trauma research biologists, epidemiologists, and nosologists to map the correspondence between the clinical and biological indicators of psychopathology are necessary to advance validation and further understanding of PTSD.

AB Objectives. We sought to determine whether groups traditionally most vulnerable to disasters would be more likely than would be others to perceive population level risk as high (as measured by the estimated color-coded alert level) would worry more about terrorism, and would avoid activities because of terrorism concerns.
Methods. We conducted a random digit dial survey of the Los Angeles County population October 2004 through January 2005 in 6 languages. We asked respondents what color alert level the country was under, how often they worry about terrorist attacks, and how often they avoid activities because of terrorism. Multivariate regression modeled correlates of worry and avoidance, including mental illness, disability, demographic factors, and estimated color-coded alert level.
Results. Persons who are mentally ill, those who are disabled, African Americans, Latinos, Chinese Americans, Korean Americans, and non-US citizens were more likely to perceive population-level risk as high, as measured by the estimated color-coded alert level. These groups also reported more worry and avoidance behaviors because of concerns about terrorism.
Conclusions. Vulnerable populations experience a disproportionate burden of the psychosocial impact of terrorism threats and our national response. Further studies should investigate the specific behaviors affected and further elucidate disparities in the disaster burden associated with terrorism and terrorism policies.

AB Members of the Sprouty family encode novel proteins that are thought to function primarily as intracellular antagonists of the Ras-signaling pathway. Increased Ras signaling is a critical characteristic of human lung adenocarcinoma, the most common type of non-small cell lung cancer. Sprouty 2 is expressed in the lung epithelium, the tissue layer from which lung cancers arise. We hypothesized that overexpression of Sprouty 2 in the distal lung epithelium would inhibit lung tumorigenesis. To test the hypothesis, the consequences of overexpressing Sprouty 2 in the distal lung epithelium on urethane-induced mouse lung tumorigenesis were determined. Urethane is a chemical carcinogen found in tobacco smoke that causes activating mutations in Kras and induces lung tumors in mice. Sprouty 2-overexpressor mice developed significantly fewer lung tumors compared with their littermate controls (113.2 +/- 1.1 versus 18.1 +/- 1.3, P = 0.006). Tumor diameter was also significantly smaller in Sprouty 2 overexpressors (0.85 mm +/- 0.03 versus 0.95 mm +/- 0.02, P = 0.005). Sprouty 2 overexpression did not alter Kras mutational frequencies in urethane-induced tumors, suggesting that the tumor-suppressing effect of Sprouty 2 overexpression acts at a stage after Kras mutation, perhaps by interfering with receptor tyrosine kinase-induced signaling. These results demonstrate that Sprouty 2 overexpression inhibited both tumor initiation and subsequent tumor growth.

ID CHRONIC RHINOSINUSITIS; COMPUTED-TOMOGRAPHY; PARANASAL SINUSES; CT;
SINUSITIS; MRI; RADIATION
AB Background: Concerns over radiation exposure with paranasal sinus computed tomography (CT) have recently evolved. Magnetic resonance imaging (MRI) may be more advantageous in this regard, but the diagnostic assessment of MRI in chronic rhinosinusitis (CRS) has not been reported. The purpose of this study was to determine the correlation between CT- and MRI-based staging and diagnosis of CRS.
Methods: Paired CT and MRI scans of 89 adult patients who were imaged by both modalities within a 3-month time period for evaluation of pituitary disease were scored for sinus disease using the Lund-Mackay system in a randomized and blinded fashion. The Lund scores were compared for similarity, correlation, and diagnostic classification between modalities.
Results: The mean Lund scores were 2.3 +/- 0.6 (95% CI) for CT-based staging and 2.1 +/- 0.5 for MRI-based staging with a median time interval between scans of 3 days. The difference means was not statistically significant (p = 0.444, paired t-test). Correlation analysis revealed a significant association between CT- and MRI-based scores (Pearson's r = 0.837, p < 0.001). Disease classification agreement analysis using published Lund score cutoffs (3 versus 4) for the likelihood of true sinus disease revealed that CT- and MRI-based scoring agreed on 76 cases (85.4%). Disagreement occurred in 13 cases (kappa: 0.557, p < 0.001). Sensitivity, specificity, positive predictive value, and negative predictive value were 66.7, 90.1, 63.2, and 91.4%, respectively.
Conclusion: Lund-Mackay staging of sinus disease by MRI is closely correlated to corresponding staging based on CT. MRI does not significantly overstage or overclassify patients with sinus disease.

AB Background: LL-37, all innate immunity protein expressed within sinonasal mucosa, has in vitro antibacterial and antifungal properties as Well as efficacy against preformed Pseudomonas aeruginosa biofilms. We hypothesize that a 24 amino acid peptide derivative of LL-37 will show efficacy against biofilm-forming P. aeruginosa in ail established animal model of sinusitis.
Methods: Five groups of six New Zealand rabbits were each infected with P. aeruginosa (PAO-1) and fitted with irrigating catheters 7 days later. Each group was instilled with either one of three different concentrations of peptide, a positive control of topical tobramycin, or the carrier solution without the peptide once a day for 10 days. Nasal diluent was collected throughout the irrigation period to assess for persistence or resolution of infection by determining colony-forming units (CFU). At study end, sinus mucosa was harvested for histological assessment of inflammation and SEM evaluation for ciliary integrity and presence Of biofilms.
Results: Topical tobramycin at 400X minimum inhibitory concentration and 2.5 mg/mL of peptide were effective in significantly lowering CFUs after 10 days of irrigation. Histological evaluation showed increased signs of inflammation in a dose-dependent manner within mucosa and bone of the groups receiving the peptide. SEM analysis showed ciliary loss in a dose-dependent manner. Biofilms were present ill all groups except for the highest concentration of peptide and tobramycin.
Conclusion: High concentrations of LL-37-derived peptide showed in vivo ability to eradicate Pseudomonas biofilms and decrease bacterial counts. However, increasing concentrations of peptide showed proinflammatory and ciliotoxic effects oil sinus mucosa.

NEUROCOGNITIVE FUNCTION
AB BACKGROUND: Much attention in the literature has focused on the relationship between perioperative microemboli during cardiac and vascular surgery and postoperative cognitive decline. Transcranial Doppler ultrasonography (TCD) has been used to measure high-intensity transient signals (HITS), which represent microemboli during cardiac, vascular, and orthopedic surgery. The purpose of this study was to systematically examine the literature with respect to HITS and postoperative cognitive function.
METHODS: Systematic PubMed searches identified articles related to the use of TCD and cognitive function in the surgical setting.
RESULTS: The literature remains largely undecided on the role of HITS and cognitive impairment after Surgery, with most studies being underpowered to show a relationship. Although the cognitive effects of HITS may be difficult to detect, subclinical microemboli present potential harm, which may be modifiable.
CONCLUSIONS: TCD represents a tool for intraoperative cerebral monitoring to reduce the number of HITS during surgery. (C) 2009 Published by Elsevier Inc.

AB The distinction of ovarian clear cell carcinomas (CCCs) from high-grade serous carcinomas (HG-SCs) is sometimes a diagnostic challenge. With the recognition that CCCs respond poorly to conventional chemotherapy there are efforts to initiate clinical trials for CCC, making accurate diagnosis critical. The purpose Of this Study was to test and validate a set of antibodies that could aid in the diagnosis Of CCC, using a series of cases from different centers in North America. Using a test set of 133 CCCs, we identified the following markers: Cyclin E, estrogen receptor, hepatocyte nuclear factor (HNF)-1 beta, Ki-67, p21, p53, and Wilms tumor (WT)1 that show significant discrimination from 200 HG-SCs. For validation, these markers were characterized on an independent set of 104 CCCs from 3 other centers. There were no significant differences in expression of these 7 markers between the independent test and validation sets of CCC. Combining all CCC cases (N = 237), HNF-1 beta showed the highest sensitivity (82.5%) and specificity (95.2%) for CCC, and WT1 for HG-SC (sensitivity: 79.9%, specificity: 97.4%). A diagnostic panel consisting of WT1. ER, and HNF-1 beta demonstrated nearly identical performance as a panel using all 7 markers in distinguishing CCCs from HG-SCs, correctly classifying 84% of cases. Three percent of cases were misclassified and 13% carried an uninformative triple negative immunophenotype. CCCs show a distinct, reproducible immunophenotype, compared with HG-SCs, and a panel of 3 immunomarkers can serve as a diagnostic aid in problematic cases.

AB Spindle cell lesions of the urinary bladder are uncommon, but when encountered in clinical practice, pose a difficult diagnostic challenge as the differential diagnostic considerations ire Vast. Pseudosarcomatous processes significantly overlap with malignant tumors (sarcomatoid urothelial carcinoma and leiomyosarcoma) ill their morphology and published immunohistochemical profile [pancytokeratin pan (CK), smooth Muscle actin (SMA), and desmin]. p63 has been studied rarely and CK 5/6 and CK 34 beta E12 have not been analyzed in the bladder in this diagnostic context. In the current study, 45 typical examples of spindle cell lesions [10 pseudosarcomatous myofibroblastic proliferations (PMP), 22 sarcomatoid urothelial carcinomas, and 13 smooth Muscle tumors] of the urinary bladder were immunostained with a panel containing broad spectrum anticytokeratin antibodies (OSCAR or AE1/ AE3), as well as antibodies to CK 34 beta 3E12, CK 5/6, p63, SMA, and anaplastic lymphoma kinase (ALK). The immunoreactivity was as follows: PMP-CK (OSCAR) 7/10 (70%), CK (AE1/AE3) 7/9 (78%), CK 34 beta E12 0/10 MY.), CK 5/6 0/9 (0%), p63 0/9 (0%,,), SMA 10/10 (100%), ALK 2/10 (20%), sarcomatoid urothelial carcinoma-CK (OSCAR) 15/22 (68%), CK (AE1/AE3) 14/20 (70%) CK 34 beta E12 5/20 (25%), CK5/6 6/22 (27%), p63 11/22 (50%), SMA 16/22 (73%), ALK 0/22 (0%); and smooth muscle tumors-CK (OSCAR) 7/13 (54%), CK (AE1/AE3) 7/12 (58%, ), CK 34 beta E12 0/12 (0%,), CK 5/6 0/12 (0%), p63 3/13 (23%), SMA II/13 (85%), ALK 0/13 (0%,). Positivity for keratin was typically Focal to moderate ill smooth muscle tumors and more commonly moderate to diffuse ill sarcomatoid carcinomas and PMP. Our data indicate that there is significant immunohistochemistry I overlap between the different spindle cell lesions, each of which has unique clinicopathologic, prognostic, and therapeutic ramifications. Within the context of morphology, an immunohistochemical panel composed of broad-spectrum antibodies to cytokeratin as well as antibodies to SMA, ALK, p63, and CK 5/6 will be a useful diagnostic adjunct,: a combination of pankeratin, SMA, and ALK positivity favors PMP; expression of several cytokeratin and especially CK 34 beta E12 and CK 5/6 with p63 favors sarcomatoid carcinoma and SMA positivity with overall absence or other markers favors leiomyosarcoma.

AB Background: This study examined recognition of all 5 early warning signs/symptoms of stroke and appropriate first action to call 9-1-1 across stroke risk groups, Methods: Data from 264,684 adults from the 2003 Behavioral Risk Factor Surveillance System were examined. Recognition of the 5 warning signs/symptoms of stroke and appropriate first action to call 9-1-1 was compared among 3 stroke risk groups no stroke risk factors, stroke risk factors, and prior stroke, using multiple logistic regression controlling for covariates. Results: Recognition of the 5 individual warning signs of stroke ranged from 82% to 98%. Cumulative recognition of all 5 warning signs of stroke ranged from 30.8% in individuals with prior stroke to 12.6% in those with no stroke risk factors,. Cumulative recognition of all 5 warning signs of stroke and taking appropriate action to call 9-1-1 ranged from 26.1% in individuals with prior stroke to 11.2% in those with no stroke risk factors. Adjusted odds ratios for recognition of all 5 symptoms was 3.35 for individuals with previous stroke and 1.15 for individuals with stroke risk factors, compared with the reference group (individuals without stroke risk factors). Adjusted odds ratios for recognition of all 5 symptoms and taking appropriate action to call 9-1-1 was 3.06 for individuals with previous stroke and 1.14 for individuals with stroke risk factors, Conclusions: Recognition of individual stroke warning symptoms is high in general. Cumulative recognition of stroke warning signs and taking appropriate action is very low, although higher in those with prior stroke.

TI Uric Acid Directly Promotes Human T-Cell Activation
SO AMERICAN JOURNAL OF THE MEDICAL SCIENCES
LA English
DT Article
DE Uric acid; T cells; Gout; Autoimmunity
ID ENDOGENOUS ADJUVANTS; IMMUNE-SYSTEM; PATHOGENESIS
AB Background: Abnormally high serum uric acid levels have been associated with several disease conditions including gout and kidney stone disease. More recently, it was shown that uric acid crystals stimulate dendritic cell maturation, activate the NALP3 inflamasome, and enhance antigen-specific immune responses. We hypothesize that uric acid can also stimulate T cells directly and in the absence of antigen presentation. Methods: Purified primary human T cells were incubated with and without uric acid at concentrations of 50, 100, 150, and 200 mu g/mL. The expression of T-cell activation markers CD25 and CD70 was assessed by flow cytometry. In other experiments, Jurkat T cells were used and the expression of the costimulatory molecule CD70 was determined at the mRNA level. Result: Uric acid directly activates primary human T cells in tire absence of antigen presentation. Furthermore, primary human T cells and Jurkat T cells treated with uric acid overexpress the costimulatory molecule CD70, which plays an important role in T cell-B cell interaction and antibody production. Conclusions: The finding that uric acid directly promotes T-cell activation in ail antigen-independent system is novel and might play a mechanistic role in the inflammatory response observed in gouty arthritis and other immune-mediated diseases.

SO AMERICAN JOURNAL OF TRANSLATIONAL RESEARCH

DT Review
DE Estrogen; estrogen therapy; hormone therapy; cognition; Alzheimer's
disease; postmenopausal cognition; women's health initiative
AB Over a decade of converging findings from clinical, observational and basic science research indicate that estrogen administration during the menopausal transition exerts beneficial effects on cognition and decreases a woman's risk of developing Alzheimer's disease (AD) later in life. This review article stresses the research focus of AD prevention, and introduces hormone therapy (HT) as a probable catalyst that may achieve this goal. Furthermore, this article outlines 3 mechanisms proposed to mediate estrogen's beneficial effects, discusses the controversy surrounding HT administration, and presents the most promising estrogen related research in AD prevention and treatment. Although controversial, cumulative evidence suggests that the potential of estrogen initiated during perimenopause to prevent AD needs to be systematically evaluated.

AB Cytomegalovirus (CMV) reactivation is a well-described complication of solid organ transplantation. These studies were performed to (1) determine if cardiac allograft transplantation of latently infected recipients results in reactivation of CMV and (2) determine what impact CMV might have on development of graft acceptance/tolerance. BALB/c cardiac allografts were transplanted into C57BL/6 mice with/without latent murine CMV (MCMV). Recipients were treated with gallium nitrate induction and monitored for graft survival, viral immunity and donor reactive DTH responses. Latently infected allograft recipients had similar to 80% graft loss by 100 days after transplant, compared with similar to 8% graft loss in naive recipients. PCR evaluation demonstrated that MCMV was transmitted to cardiac grafts in all latently infected recipients, and 4/8 allografts had active viral transcription compared to 0/6 isografts. Latently infected allograft recipients showed intragraft IFN-alpha expression consistent with MCMV reactivation, but MCMV did not appear to negatively influence regulatory gene expression. Infected allograft recipients had disruption of splenocyte DTH regulation, but recipient splenocytes remained unresponsive to donor antigen even after allograft losses. These data suggest that transplantation in an environment of latent CMV infection may reactivate virus, and that intragraft responses disrupt development of allograft acceptance.

AB We studied the effects of indirect allorecognition on the induction and maintenance phases of tolerance in miniature swine cotransplanted with heart and kidney allografts. MHC class I-mismatched heart and kidney grafts were cotransplanted in recipients receiving CyA for 12 days. Recipients were unimmunized or immunized with a set of donor-derived or control third-party MHC class I peptides either 21 days prior to transplantation or over 100 days after transplantation. T-cell proliferation, delayed type hypersensitivity reaction (DTH) and antibody production were assessed. All animals injected with donor MHC class I peptides developed potent indirect alloresponses specific to the immunizing peptides. While untreated recipients developed stable tolerance, all animals preimmunized with donor allopeptides rejected kidney-heart transplants acutely. In contrast, when peptide immunization was delayed until over 100 days after kidney-heart transplantation, no effects were observed on graft function or in vitro measures of alloimmunity. Donor peptide immunization prevented tolerance when administered to recipients pre transplantation but did not abrogate tolerance when administered to long-term survivors post transplantation. This suggests that the presence of T cells activated via indirect allorecognition represent a barrier to the induction but not the maintenance of tolerance.

MANAGEMENT
AB The Opioid Renewal Clinic (ORC) is a pharmacist-run program that assists primary care providers in the management of chronic pain patients with aberrant behavior or high risk of prescription opioid abuse. In this study, charts of all discharged patients over a 22-month span (n = 86) were reviewed for outcomes for two years after discharge. The most frequent reason for discharge from the program was recurrent positive urine drug screens for illicit substances (n = 40; 47%). Only 15 (17%) were seen for addiction treatment in the two-year follow-up period. Forty-one percent of patients (n = 35) were prescribed opioids within two years of discharge. There was a positive correlation between length of time in the ORC and receipt of opioids post discharge. These outcomes reveal areas of need in the management of this complex population.

TI Theories of Addiction: Methamphetamine Users' Explanations for

ID INTERNATIONAL NEUROPSYCHIATRIC INTERVIEW; COCAINE-DEPENDENT PATIENTS;
DSM-IV; IMPULSIVITY; REWARD; ABUSE; WITHDRAWAL; BEHAVIOR; BRAIN;
DYSREGULATION
AB A variety of preclinical models have been constructed to emphasize unique aspects of addiction-like behavior. These include Negative Reinforcement (Pain Avoidance), Positive Reinforcement (Pleasure Seeking), Incentive Salience (Craving), Stimulus Response Learning (Habits), and Inhibitory Control Dysfunction (Impulsivity). We used a survey to better understand why methamphetamine-dependent research volunteers (N = 73) continue to use methamphetamine, or relapse to methamphetamine use after a period of cessation of use. All participants met DSM-IV criteria for methamphetamine abuse or dependence, and did not meet criteria for other current Axis I psychiatric disorders or dependence on other drugs of abuse, other than nicotine. The questionnaire consisted of a series of face-valid questions regarding drug use, which in this case referred to methamphetamine use. Examples of questions include: Do you use drugs mostly to make bad feelings like boredom, loneliness, or apathy go away?, Do you use drugs mostly because you want to get high?, Do you use drugs mostly because of cravings?, Do you find yourself getting ready to take drugs without thinking about it?, and Do you impulsively take drugs?. The scale was anchored at 1 (not at all) and 7 (very much). For each question, the numbers of participants rating each question negatively (1 or 2), neither negatively or affirmatively (3-5), and affirmatively (6 or 7) were tabulated. The greatest number of respondents (56%) affirmed that they used drugs due to pleasure seeking. The next highest categories selected were impulsivity (27%) and habits(25%). Surprisingly, many participants reported that pain avoidance (30%) and craving (30%) were not important for their drug use. Results from this study support the contention that methamphetamine users (and probably other drug users as well) are more heterogeneous than is often appreciated, and imply that treatment development might be more successful if treatments targeted subtypes of patients, though a range of limitations to the approach used are acknowledged.

AB This post hoc analysis compared the safety of atomoxetine treatment of ADHD in adults with or without comorbid alcohol abuse/dependence. Study completion rates in patients receiving atomoxetine were comparable between heavy drinkers (60.9%) and patients with no alcohol-use disorder (71.0%) but lower in nonheavy drinkers (35.7%); however, there was no significant difference in discontinuation rates due to adverse events or lack of efficacy among these groups. Alcohol-use disorder patients, especially heavy drinkers, generally experienced the greatest frequency of treatment-emergent adverse events in both the atomoxetine and placebo groups. Vital signs and measures of hepatic function were not significantly different among the 3 drinking status groups taking atomoxetine. ( Am J Addict 2009; 18: 393-401)
