AB It has been recently hypothesized that many of the signals detected in genome-wide association studies (GWAS) to T2D and other diseases, despite being observed to common variants, might in fact result from causal mutations that are rare. One prediction of this hypothesis is that the allelic associations should be population-specific, as the causal mutations arose after the migrations that established different populations around the world. We selected 19 common variants found to be reproducibly associated to T2D risk in European populations and studied them in a large multiethnic case-control study (6,142 cases and 7,403 controls) among men and women from 5 racial/ethnic groups (European Americans, African Americans, Latinos, Japanese Americans, and Native Hawaiians). In analysis pooled across ethnic groups, the allelic associations were in the same direction as the original report for all 19 variants, and 14 of the 19 were significantly associated with risk. In summing the number of risk alleles for each individual, the per-allele associations were highly statistically significant (P < 10(-4)) and similar in all populations (odds ratios 1.09-1.12) except in Japanese Americans the estimated effect per allele was larger than in the other populations (1.20; P-het = 3.8x10(-4)). We did not observe ethnic differences in the distribution of risk that would explain the increased prevalence of type 2 diabetes in these groups as compared to European Americans. The consistency of allelic associations in diverse racial/ethnic groups is not predicted under the hypothesis of Goldstein regarding "synthetic associations'' of rare mutations in T2D.

TI The Effect of Raltegravir Intensification on Low-level Residual Viremia

Controlled Trial

AB Background: Most HIV-1-infected patients on effective antiretroviral therapy (ART) with plasma HIV-1 RNA levels below the detection limits of commercial assays have residual viremia measurable by more sensitive methods. We assessed whether adding raltegravir lowered the level of residual viremia in such patients.
Methods and Findings: Patients receiving ART who had plasma HIV-1 RNA levels below 50 copies/mL but detectable viremia by single copy assay (SCA) were randomized to add either raltegravir or placebo to their ART regimen for 12 weeks; patients then crossed-over to the other therapy for an additional 12 weeks while continuing pre-study ART. The primary endpoint was the plasma HIV-1 RNA by SCA averaged between weeks 10 and 12 (10/12) compared between treatment groups. Fifty-three patients were enrolled. The median screening HIV-1 RNA was 1.7 copies/mL. The HIV-1 RNA level at weeks 10/12 did not differ significantly between the raltegravir-intensified (n = 25) and the placebo (n = 24) groups (median 1.2 versus 1.7 copies/mL, p = 0.55, Wilcoxon rank sum test), nor did the change in HIV-1 RNA level from baseline to week 10/12 (median -0.2 and -0.1 copies/mL, p = 0.71, Wilcoxon rank sum test). There was also no significant change in HIV-1 RNA level from weeks 10/12 to weeks 22/24 after patients crossed-over. There was a greater CD4 cell count increase from baseline to week 12 in the raltegravir-intensified group compared with the placebo group (+42 versus -44 cells/mm(3), p = 0.082, Wilcoxon rank sum test), which reversed after the cross-over. This CD4 cell count change was not associated with an effect of raltegravir intensification on markers of CD4 or CD8 cell activation in blood.
Conclusion: In this randomized, double-blind cross-over study, 12 weeks of raltegravir intensification did not demonstrably reduce low-level plasma viremia in patients on currently recommended ART. This finding suggests that residual viremia does not arise from ongoing cycles of HIV-1 replication and infection of new cells. New therapeutic strategies to eliminate reservoirs that produce residual viremia will be required to eradicate HIV-1 infection.

AB The Pneumococcal serine-rich repeat protein (PsrP) is a pathogenicity island encoded adhesin that has been positively correlated with the ability of Streptococcus pneumoniae to cause invasive disease. Previous studies have shown that PsrP mediates bacterial attachment to Keratin 10 (K10) on the surface of lung cells through amino acids 273-341 located in the Basic Region (BR) domain. In this study we determined that the BR domain of PsrP also mediates an intra-species interaction that promotes the formation of large bacterial aggregates in the nasopharynx and lungs of infected mice as well as in continuous flow-through models of mature biofilms. Using numerous methods, including complementation of mutants with BR domain deficient constructs, fluorescent microscopy with Cy3-labeled recombinant (r) BR, Far Western blotting of bacterial lysates, co-immunoprecipitation with rBR, and growth of biofilms in the presence of antibodies and competitive peptides, we determined that the BR domain, in particular amino acids 122-166 of PsrP, promoted bacterial aggregation and that antibodies against the BR domain were neutralizing. Using similar methodologies, we also determined that SraP and GspB, the Serine-rich repeat proteins (SRRPs) of Staphylococcus aureus and Streptococcus gordonii, respectively, also promoted bacterial aggregation and that their Non-repeat domains bound to their respective SRRPs. This is the first report to show the presence of biofilm-like structures in the lungs of animals infected with S. pneumoniae and show that SRRPs have dual roles as host and bacterial adhesins. These studies suggest that recombinant Non-repeat domains of SRRPs (i.e. BR for S. pneumoniae) may be useful as vaccine antigens to protect against Gram-positive bacteria that cause infection.

AB Upon infection of mammalian cells, enterohemorrhagic E. coli (EHEC) O157:H7 utilizes a type III secretion system to translocate the effectors Tir and EspF(U) (aka TccP) that trigger the formation of F-actin-rich 'pedestals' beneath bound bacteria. EspF(U) is localized to the plasma membrane by Tir and binds the nucleation-promoting factor N-WASP, which in turn activates the Arp2/3 actin assembly complex. Although N-WASP has been shown to be required for EHEC pedestal formation, the precise steps in the process that it influences have not been determined. We found that N-WASP and actin assembly promote EHEC-mediated translocation of Tir and EspF(U) into mammalian host cells. When we utilized the related pathogen enteropathogenic E. coli to enhance type III translocation of EHEC Tir and EspF(U), we found surprisingly that actin pedestals were generated on N-WASP-deficient cells. Similar to pedestal formation on wild type cells, Tir and EspF(U) were the only bacterial effectors required for pedestal formation, and the EspF(U) sequences required to interact with N-WASP were found to also be essential to stimulate this alternate actin assembly pathway. In the absence of N-WASP, the Arp2/3 complex was both recruited to sites of bacterial attachment and required for actin assembly. Our results indicate that actin assembly facilitates type III translocation, and reveal that EspF(U), presumably by recruiting an alternate host factor that can signal to the Arp2/3 complex, exhibits remarkable versatility in its strategies for stimulating actin polymerization.

AB Selenium (Se) has been known for many years to have played a role in boosting the immune function, but the manner in which this element acts at the molecular level in host defence and inflammatory diseases is poorly understood. To elucidate the role of Se-containing proteins in the immune function, we knocked out the expression of this protein class in T-cells or macrophages of mice by targeting the removal of the selenocysteine tRNA gene using loxP-Cre technology. Mice with selenoprotein-less T-cells manifested reduced pools of mature and functional T-cells in lymphoid tissues and an impairment in T-cell-dependent antibody responses. Furthermore, selenoprotein deficiency in T-cells led to an inability of these cells to suppress reactive oxygen species production, which in turn affected their ability to proliferate in response to T-cell receptor stimulation. Selenoprotein-less macrophages, on the other hand, manifested mostly normal inflammatory responses, but this deficiency resulted in an altered regulation in extracellular matrix-related gene expression and a diminished migration of macrophages in a protein gel matrix. These observations provided novel insights into the role of selenoproteins in the immune function and tissue homeostasis.

AB The changing healthcare environment is creating opportunities for psychologists to practice in non-traditional settings. This paper describes a Veterans Health Administration (VA) initiative to integrate psychologists into its Home Based Primary Care (HBPC) program. As psychologists new to HBPC are learning, the home offers opportunities and challenges not routinely encountered in the traditional office setting. Home-based psychology offers improved access to mental health services, more effective treatment planning, and more accurate assessments in an underserved patient population. Psychologists practicing in this setting also encounter challenges in dealing with patient confidentiality, distractions, role confusion and boundaries, time management, safety, and professional competency. The VA experience is an instructive case example for psychologists considering this growing field of practice. This paper offers lessons learned from this VA initiative and discusses strategies for dealing with potential challenges.

AB The purpose of this study was to assess the comorbidity between chronic pain and posttraumatic stress disorder (PTSD) and examine the extent to which PTSD is associated with changes in the multidimensional experience of pain in a sample of Veterans with chronic pain. It was hypothesized that Veterans with comorbid chronic pain and PTSD would report significantly higher scores on measures of pain intensity, pain behaviors, pain-related disability, and affective distress than Veterans with pain alone. Data were obtained from 149 Veterans who completed self-report questionnaires as part of their participation in a Psychology Pain Management program at a northeastern Department of Veterans Affairs health care facility. Analyses indicated that 49% of the sample met criteria for PTSD. A multivariate analysis of covariance was conducted with age, sex, pain duration, and depressive symptom severity as covariates. In partial support of our hypothesis, the presence of PTSD was found to contribute significantly to measures of affective distress, even after controlling for the effects of depressive symptom severity. The implications of these data are discussed.

TI Identifying quality improvement intervention evaluations: is consensus
achievable?
SO QUALITY & SAFETY IN HEALTH CARE
LA English
DT Article
ID RANDOMIZED CONTROLLED-TRIAL; HEALTH-CARE; FRAMEWORK
AB Background The diversity of quality improvement interventions (QIIs) has impeded the use of evidence review to advance quality improvement activities. An agreed-upon framework for identifying QII articles would facilitate evidence review and consensus around best practices.
Aim To adapt and test evidence review methods for identifying empirical QII evaluations that would be suitable for assessing QII effectiveness, impact or success.
Design Literature search with measurement of multilevel inter-rater agreement and review of disagreement.
Methods Ten journals (2005-2007) were searched electronically and the output was screened based on title and abstract. Three pairs of reviewers then independently rated 22 articles, randomly selected from the screened list. Kappa statistics and percentage agreement were assessed. 12 stakeholders in quality improvement, including QII experts and journal editors, rated and discussed publications about which reviewers disagreed.
Results The level of agreement among reviewers for identifying empirical evaluations of QII development, implementation or results was 73% (with a paradoxically low kappa of 0.041). Discussion by raters and stakeholders regarding how to improve agreement focused on three controversial article selection issues: no data on patient health, provider behaviour or process of care outcomes; no evidence for adaptation of an intervention to a local context; and a design using only observational methods, as correlational analyses, with no comparison group.
Conclusion The level of reviewer agreement was only moderate. Reliable identification of relevant articles is an initial step in assessing published evidence. Advancement in quality improvement will depend on the theory-and consensus-based development and testing of a generalizable framework for identifying QII evaluations.

AB Purpose: To reassess the accuracy of the 10-minute delayed scan to differentiate both lipid-rich and lipid-poor lesions in a large cohort of patients.
Materials and Methods: This HIPAA-compliant retrospective study had institutional review board approval; the need for informed consent was waived. A multidetector computed tomography (CT) adrenal protocol (unenhanced, dynamic contrast material-enhanced, and 10-minute delayed CT) was used in 314 consecutive patients (201 women, 113 men; mean age, 63.6 years) for the period from January 2006 through February 2009. The mean adrenal attenuation during all three CT phases was measured by two readers, and the relative percentage washout (RPW) and absolute percentage washout (APW) values were calculated. APW and RPW receiver operating characteristic (ROC) analysis was performed to evaluate the strength of the tests.
Results: There were 323 adrenal lesions (213 left, 110 right) consisting of 307 adenomas and 16 nonadenomas. The sensitivity, specificity, and accuracy for the RPW test at a washout threshold of 50% were 55.7%, 100%, and 57.9%, respectively; at 40% were 76.9%, 93.7%, and 77.7%; and at 35% were 81.4%, 93.7%, and 82.0%. The sensitivity, specificity, and accuracy for the APW test at a 60% threshold were 52.1%, 93.3%, and 54.0%, respectively; at 55% were 62.5%, 93.3%, and 64.0%; and at 50% were 71.3%, 80.0%, and 71.7%. Areas under the ROC curve were 0.85 (95% confidence interval: 0.75, 0.95) and 0.91 (95% confidence interval: 0.85, 0.97) for the APW and RPW tests, respectively, to detect adenomatous disease.
Conclusion: The 10-minute delayed adrenal enhancement washout test has reduced sensitivity for the characterization of adrenal adenomas compared with results from prior studies. (C) RSNA, 2010

AB Purpose: To determine whether magnetic resonance (MR) imaging with diffusion-weighted (DW) imaging can help discriminate between radiologically indeterminate benign and malignant orbital masses and to identify optimal apparent diffusion coefficient (ADC) thresholds for such discrimination.
Materials and Methods: Informed consent was waived for this HIPAA-compliant institutional review board-approved retrospective study. Forty-seven orbital masses imaged with echo-planar DW imaging were identified in 47 patients (25 female patients, 22 male patients; average age, 35 years). A fellowship-trained orbital surgeon determined reference-standard diagnoses on the basis of chart review, and a neuroradiology fellow and senior neuroradiologist who were blinded to the diagnoses selected a region of interest for each lesion by consensus. ADC was calculated from signal intensity on DW images obtained with b = 1000 and b = 0 sec/mm(2). Lesion ADC was also compared with that of normal-appearing white matter (ADC ratio). The Student t test was used to compare groups. Receiver operating characteristic analysis was performed. Intraobserver agreement was assessed with a repeat data collection.
Results: Malignant lesions had lower ADCs than benign lesions, irrespective of patient age (P < .02) and in adults specifically (P < .05). Lymphomas had lower ADCs than pseudo-tumors (P < .001). An ADC of less than 1.0 x 10(-3) mm(2)/sec and an ADC ratio of less than 1.2 were optimal for predicting malignancy (sensitivity, 63% for both; specificity, 84% and 90%, respectively; and accuracy, 77% and 81%, respectively). Lymphoma was differentiated from pseudotumor with 100% accuracy (in 16 of 16 cases) by using these values. Infiltrative lesions that were hypointense on T2-weighted images were better characterized with DW imaging than lesions that were hyperintense or well defined.
Conclusion: Echo-planar DW MR imaging can help characterize indeterminate orbital masses. (C) RSNA, 2010

AB Purpose: To describe the magnetic resonance (MR) imaging and diffusion-weighted (DW) imaging features of ocular adnexal lymphomas (OALs), to determine the diagnostic accuracy of apparent diffusion coefficient (ADC) for discriminating OALs from other orbital mass lesions, and to assess whether variations in ADC constitute a reliable biomarker of OAL response to therapy.
Materials and Methods: Institutional ethical committee approval and informed consent were obtained. In this prospective study, 114 white subjects (65 females and 49 males) were enrolled. Thirty-eight patients with histopathologically proved OAL underwent serial MR and DW imaging examination of the orbits. ADCs of OALs were compared with those of normal orbital structures, obtained in 18 healthy volunteers, and other orbital mass lesions, prospectively acquired in 58 patients (20 primary non-OAL neoplasms, 15 vascular benign lesions, 12 inflammatory lesions, 11 metastases). Interval change in ADC of OALs before and after treatment was analyzed in 29 patients. Analysis of covariance and a paired t test were used for statistical analysis.
Results: Baseline ADCs in OALs were lower than those in normal structures and other orbital diseases (P < .001). An ADC threshold of 775 x 10(-6) mm(2)/sec resulted in 96% sensitivity, 93% specificity, 88% positive predictive value, 98.2% negative predictive value, and 94.4% accuracy in OAL diagnosis. Following appropriate treatment, 10 (34%) of 29 patients showed OAL volumetric reduction, accompanied (n = 7) or preceded (n = 3) by an increase in ADC (P = .005). Conversely, a further reduction of ADC was observed in the seven patients who experienced disease progression (P < .05).
Conclusion: ADC permits accurate diagnosis of OALs. Interval change in ADC after therapy represents a helpful tool for predicting therapeutic response. (C) RSNA, 2010

AB Emergency airway management is associated with a high complication rate. Evaluating the patient prior to airway management is important to identify patients with increased risk of failed airways. Pre-oxygenation of critically ill patients is less effective in comparison to less sick patients. Induction agents are often required, but most induction agents are associated with hypotension during emergency intubation. Use of muscle relaxants is controversial for emergency intubation, but they are commonly used in the emergency department. Supervision of emergency airway management by attending physicians significantly decreases complications. Standardized algorithms may increase the success of emergency intubation. Attention should be paid to cardiopulmonary stability in the immediate post-intubation period.

AB We describe an approach for performing single-molecule binding experiments on time scales from hours to days, allowing for the observation of slower kinetics than have been previously investigated by single-molecule techniques. Total internal reflection fluorescence microscopy is used to image the binding of labeled ligand to molecules specifically coupled to the surface of an optically transparent flow cell. Long-duration experiments are enabled by ensuring sufficient positional, chemical, thermal, and image stability. Principal components of this experimental stability include illumination timing, solution replacement, and chemical treatment of solution to reduce photodamage and photobleaching; and autofocusing to correct for spatial drift.

AB Introduction and objectives. The development of second-generation optical coherence tomography (i.e. Fourier domain optical coherence tomography, FD-OCT) has made it possible to perform high speed pullbacks during image acquisition without the need for transient occlusion of the coronary artery. The objective of this study was to assess the reproducibility of FD-OCT systems for characterizing plaque and evaluating stent implantation in patients undergoing a percutaneous coronary intervention.
Methods. The study included 45 patients scheduled for percutaneous coronary intervention who were enrolled between May and December 2008. Image acquisition was performed by FD-OCT using a non-occlusive technique and employing pullback speeds ranging from 5 to 20 mm/s. Interstudy, interobserver and intraobserver reproducibility of plaque characterization and stent analysis were assessed.
Results. Fourier domain imaging was successfully performed in all patients (n=45). The average flush rate was 3 +/- 0.4 mL/s and the contrast volume per pullback was 16.1 +/- 3.5 mL. The mean pullback duration and length were 3.2 +/- 1.2 s and 53.3 +/- 12.4 mm, respectively. The interstudy reproducibility for visualizing edge dissection, tissue prolapse, intrastent dissection and malapposition was excellent (kappa=1). The kappa values for interstudy, interobserver and intraobserver agreement on plaque characterization were 0.92, 0.82 and 0.95, respectively.
Conclusions. A second-generation OCT system (i.e. FD-OCT) involving high-speed data acquisition demonstrated good interstudy, interobserver and intraobserver reproducibility for characterizing plaque and evaluating stent implantation in patients undergoing a percutaneous coronary intervention.

AB Optical coherence tomography is a recently developed high-resolution intravascular diagnostic technique. Initially, it was mainly used for characterizing atherosclerotic plaque because it served a number of functions, from identifying plaque with high lipid content to detecting macrophage accumulation, both of which are associated with plaque instability. Currently, there is growing interest in the value of optical coherence tomography in the area of coronary intervention, where the technique offers significant advantages over more widespread intravascular diagnostic techniques such as intravascular ultrasound: its higher resolution means that the vessel lumen diameter can be measured more precisely, periprocedural complications such microdissection of the coronary artery can be detected, stent apposition relative to the vessel wall can be optimized, neointimal hyperplasia can be detected after stent implantation, and neointimal thickness can be measured. It would therefore appear to be a very useful technique for interventional cardiologists. This review article considers the technical details of the technique and its applications, and compares it with other intravascular diagnostic techniques.

AB Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) include Wegener's granulomatosis, microscopic polyangiitis, and Churg-Strauss syndrome. Given their rarity, protean clinical manifestations, imperfect diagnostic tests, and wide differential diagnosis, they pose a diagnostic challenge even to experienced clinicians. This article describes diagnostic approaches for patients suspected of having one of the ANCA-associated vasculitides. The clinical findings at presentation, the role of laboratory and imaging tests, and the importance of tissue diagnosis are presented. In each section, issues relevant to the differential diagnosis of AAV are discussed

AB Group C streptococci (GCS) are common causes of veterinary diseases and may colonize humans. Human diseases due to GCS are uncommon and generally occur in the elderly and persons exposed to animals or animal products. We report a case of Streptococcus equi subsp. zooepidemicus meningitis in a horse trainer and review 36 cases of GCS meningitis reported in the literature. The median age was 48 y and the majority of patients were previously healthy. Thirty-one percent (11/36) of the reported cases followed equine exposure and 19% (7/36) ingestion of dairy products. Sixty-seven percent (24/36) were found to have concomitant bacteraemia. The case fatality rate was 31% (11/36), and 28% (7/25) of survivors were reported to have residual neurological impairments. At least 4 days of antibiotics were typically required before symptoms improved. Isolates were generally susceptible to beta-lactams. In conclusion, it is important to consider GCS in the differential of bacterial meningitis, in particular in elderly patients exposed to horses or dairy products. Beta-lactams are first-line therapy, but outcomes are poor.

AB Background: Practical, reliable "real world" measures of cognition are needed to supplement neurocognitive performance data to evaluate possible efficacy of new drugs targeting cognitive deficits associated with schizophrenia. Because interview-based measures of cognition offer one possible approach, data from the MATRICS initiative (n = 176) were used to examine the psychometric properties of the Schizophrenia Cognition Rating Scale (SCoRS) and the Clinical Global Impression of Cognition in Schizophrenia (CGI-CogS).
Method: We used classical test theory methods and item response theory to derive the 10-item Cognitive Assessment Interview (CAI) from the SCoRS and CGI-CogS ("parent instruments"). Sources of information for CAI ratings included the patient and an informant. Validity analyses examined the relationship between the CAI and objective measures of cognitive functioning, intermediate measures of cognition, and functional outcome.
Results: The rater's score from the newly derived CAI (10 items) correlate highly (r=.87) with those from the combined set of the SCoRS and CGI-CogS (41 items). Both the patient (r=.82) and the informant (r=.95) data were highly correlated with the rater's score. The CAI was modestly correlated with objectively measured neurocognition (r=-.32), functional capacity (r=-.44), and functional outcome (r=-.32), which was comparable to the parent instruments.
Conclusions: The CAI allows for expert judgment in evaluating a patient's cognitive functioning and was modestly correlated with neurocognitive functioning, functional capacity, and functional outcome. The CAI is a brief, repeatable, and potentially valuable tool for rating cognition in schizophrenia patients who are participating in clinical trials. (C) 2010 Elsevier B.V. All rights reserved.

AB Introduction: Persons diagnosed with schizophrenia demonstrate deficits in prosody recognition. To examine prosody along the schizophrenia spectrum, antipsychotic-naive schizotypa I personality disorder (SPD) subjects and healthy control subjects were compared. It was hypothesized that SPD subjects would perform more poorly: with cognitive and demographic factors contributing to the poor performance. The superior temporal gyrus (STG) was selected as the region-of-interest (ROI) given its known abnormalities in SPD and its important role in the processing of prosody.
Methods: SPD and healthy comparison (HC) subjects were matched on age, IQ and parental social-economic status (PSES). Cognitive measures included the Speech Sound Perception Test (SSPT) to examine phonological processing (SPD = 68, HC = 74) and the Verbal Fluency task to examine executive functioning (SPD = 129, HC = 138). The main experiment was a novel fMRI task of prosody identification using semantically neutral sentences spoken with emotional prosody (SPD = 16, HC=13). Finally, volumetric measurement of the superior temporal sulcus (STS), a key region for processing prosody, and partially overlapping with the STG, was performed (SPD=30, HC=30).
Results: Phonological processing and executive functioning were both impaired in SPD subjects compared with HC subjects. Contrary to the prediction, SPD subjects, as a group, were similar to HC subjects in terms of correctly indentifying the emotion conveyed and reaction time. Within the SPD group, prosody identification accuracy was influenced by executive functioning, IQ and perhaps PSES, relationships not found with HC subjects. Phonological perception aided prosody identification in both diagnostic groups. As expected, both groups activated the STG while performing the prosody identification task. However, SPD subjects may have been less "efficient" in their recruitment of STG neurons. Finally, SPD subjects demonstrated a trend toward smaller STS volumes on the left, particularly the lower bank.
Conclusions: These data suggest that subtle differences between SPD and controls in phonological processing, executive functioning, IQ and possibly PSES, contributed to difficulty in processing prosody for some SPD subjects. Published by Elsevier B.V.

AB Two major T lymphocyte lineages - alpha beta and gamma delta T cells - develop in the thymus from common precursors. Differentiation of both lineages requires signals coming from TCRs. Development of alpha beta T cells is driven at early stages by signaling from the pre-TCR, most likely in a ligand-independent fashion, and later - by signals delivered by alpha beta TCRs binding to their ligands - classical or non-classical MHC molecules. gamma delta lineage cells likewise require TCR signaling for their differentiation. Recent work from several groups suggests that TCR signaling not only ensures the developmental progression towards alpha beta and gamma delta lineages but that signal strength instructs lineage fate: weaker TCR signal results in alpha beta and stronger-in gamma delta lineage commitment. However, as most gamma delta TCRs remain orphan receptors, it is still debated whether strong signals from gamma delta TCRs in development are generated in a ligand-dependent manner (as in the case of alpha beta TCRs), ligand-independent manner (as for pre-TCR) or both. Here we summarize evidence supporting a possible role for ligands in gamma delta T cell lineage commitment and the generation of gamma delta sublineages. (C) 2010 Elsevier Ltd. All rights reserved.

AB Study Objectives: The Institute of Medicine (IOM) has called for the elimination of resident work shifts exceeding 16 hours without sleep. We sought to comprehensively evaluate the effects of eliminating or reducing shifts over 16 hours.
Design and Outcome Measures: We performed a systematic review of published and unpublished studies (1950-2008) to synthesize data on all intervention studies that have reduced or eliminated U.S. residents' extended shifts. A total of 2,984 citations were identified initially, which were independently reviewed by two authors to determine their eligibility for inclusion. All outcomes relevant to quality of life, education, and safety were collected. Study quality was rated using the U.S. Preventive Services Task Force methodology.
Measurements and Results: Twenty-three studies met inclusion criteria (kappa = 0.88 [95% Cl, 0.77-0.94] for inclusion decisions). Following reduction or elimination of extended shifts, 8 of 8 studies measuring resident quality of life found improvements. Four of 14 studies that assessed educational outcomes found improvements, 9 found no significant changes, and one found education worsened. Seven of 11 identified statistically significant improvements in patient safety or quality of care; no studies found that safety or care quality worsened.
Conclusions: In a systematic review, we found that reduction or elimination of resident work shifts exceeding 16 hours did not adversely affect resident education, and was associated with improvements in patient safety and resident quality of life in most studies. Further multi-center studies are needed to substantiate these findings, and definitively measure the effects of eliminating extended shifts on patient outcomes.

AB A 58-year-old man was seen with complaints of fevers, night sweats, weight loss, and multiple bilateral cavitary lung lesions. Mycobacterium szulgai with nearly identical antibiograms grew from separate sputum specimens 9 years apart. He was treated with a combination of clarithromycin and ethambutol with clinical, microbiologic, and radiographic resolution of disease. This is the longest untreated case of documented Mycobacterium szulgai infection reported, and offers a glimpse of its natural history when left untreated. Despite an infrequent isolation (<0.5% of cases), it is a pathogenic organism which warrants treatment.

AB BACKGROUND CONTEXT: Because of the low incidence, treatment recommendations for spinal osteosarcoma are guided by the results of small series and case reports. Many include patients who presented for treatment over the course of three to four decades.
PURPOSE: The goal of this investigation was to report the treatments, results, and overall survivorship of 26 patients treated for osteosarcoma of the spine at a single institution.
STUDY DESIGN: Retrospective prognostic series (Level III evidence).
PATIENT SAMPLE: Twenty-six patients treated at a single center for osteosarcoma of the spine over a 26-year period.
OUTCOME MEASURES: Estimation of patient survival, local recurrence, and the presence of metastatic disease.
METHODS: We performed a retrospective review of cases of osteosarcoma involving the spine treated at our institution between 1982 and 2008. Medical charts, radiology reports, pathology reports, and operative notes were reviewed for all patients. Available imaging studies were also reviewed. The log-rank test was used to compare baseline differences between groups. Survivorship analysis was performed using Kaplan-Meier methodology. The effect of Paget osteosarcoma, type of resection, presence of local recurrence, tumor size, surgical margins, and metastases on overall survival were also investigated using the log-rank test.
RESULTS: Twenty-six patients were included for review in this study. Twenty individuals were treated surgically, and 24 were treated with radiation with a mean dose of 62.2 Gy (range 20-84.7 Gy). Twenty-five patients received chemotherapy. Of those treated surgically, seven received en bloc resection. The median overall survival for all patients in our series was 29.5 months (standard error 14.7, 95% confidence interval 0.6-58). Local recurrence developed in 7 patients (27%), and metastasis occurred in 16 individuals (62%). Patients with Paget osteosarcoma had worse overall survival (p<.001).
CONCLUSIONS: Results presented here confirm a poor prognosis for patients with spinal osteosarcoma. Although combination therapies, including surgery, chemotherapy, and high-dose radiation, achieve adequate short-term survival, the 5-year mortality rate remains high. Published by Elsevier Inc.

AB Quiescent cells lacking expression of mature lineage makers and the c-Kit receptor reside in adult bone marrow. Despite their phenotypic similarity to hematopoietic stem cells, these Lin(-)Sca-1(+)c-Kit(-) cells lack myeloid and erythroid potential and long-term hematopoietic repopulating capacity, whereas, recent studies have functionally demonstrated that the Lin(-)Sca-1(+)c-Kit(-) population contains early lymphoid-committed progenitors. Examining the role of Wnt signaling in regulation of this population, we found that c-Kit(-) cells express diverse Wnt receptors and proliferate upon Wnt pathway activation in vitro and in vivo. Stimulation with Wnt3a, but not Wnt5a or Wnt11, promoted c-Kit(-) cells to give rise to myeloid and erythroid progenitors with robust self-renewal capacity measured by clonal replating. In addition, Wnt3a-stimulated c-Kit(-) cells gave rise to all hematopoietic lineages (lymphoid, myeloid, and erythroid) upon transplant into the liver of newborn recipient mice. Our study reveals that Wnt3a activates unique cell fate decisions of dormant c-Kit(-) that promotes short-term multilineage reconstitution capacity in vivo, thereby revealing a unique role for Wnt activation in hematopoiesis. Overall, our results highlight the potential of utilizing signaling molecules known to have instructive roles in regeneration to discover cell subsets residing in adult organisms with unexploited regenerative capacity.

AB Microenvironments support the maintenance of stem cells and the growth of tumors through largely unknown mechanisms. While cell-autonomous chromatin modifications have emerged as important determinants for self-renewal and differentiation of stem cells, a role for non-cell autonomous epigenetic contributions is not well established. Here, we genetically ablated the chromatin modifier Swi-independent 3a (Sin3a) in fetal Sertoli cells, which partly comprise the niche for male germline stem cells, and investigated its impact on spermatogenic cell fate and teratoma formation in vivo. Sertoli cell-specific Sin3a deletion resulted in the formation of few undifferentiated spermatogonia after birth while initially maintaining spermatogenic differentiation. Stem cell-associated markers Plzf, Gfra1, and Oct4 were downregulated in the mutant fetal gonad, while Sertoli cell markers Steel and Gdnf, which support germ cells, were not diminished. Following birth, markers of differentiating spermatogonia, Kit and Sohlh2, exhibited normal levels, but chemokine-signaling molecules chemokine (C-X-C motif) ligand 12 (CXCL12)/stromal cell-derived factor 1 (SDF1) and chemokine (C-X-C motif) receptor 4 (CXCR4), expressed in Sertoli cells and germ cells, respectively, were not detected. In the juvenile, mutant testes exhibited a progressive loss of differentiating spermatogonia and a block in spermatid elongation, followed by extensive germ cell degeneration. Sertoli cell-specific Sin3a deletion also suppressed teratoma formation by fetal germ cells in an in vivo transplantation assay. We conclude that the epigenome of Sertoli cells influences the establishment of a niche for germline stem cells as well as for tumor initiating cells. STEM CELLS 2010; 28: 1424-1434

AB Background and Purpose-Disabling stroke is costly and considered by some patients a fate worse than death. We aimed to determine whether clopidogrel reduces the rate and functional severity of stroke among high vascular risk patients, including patients with previous transient ischemic attack or ischemic stroke, who were enrolled in the Clopidogrel for High Atherothrombotic Risk and Ischemic Stabilization, Management and Avoidance (CHARISMA) trial.
Methods-We randomly assigned 15 603 high vascular risk patients to receive clopidogrel (75 mg daily) or placebo in addition to background acetylsalicylic acid and followed them for a median of 28 months. The main outcome of this prespecified substudy was the functional severity of stroke outcome events as measured by the modified Rankin Scale (mRS) score at 3 months after the stroke outcome.
Results-During follow-up, 436 (2.8%) patients had a definite adjudicated stroke and a follow-up assessment of the mRS at 3 months poststroke, of whom 202 had been randomly assigned clopidogrel and 234 placebo (relative risk reduction 14%, 95% CI: -4% to 29%, P=0.12). There was no significant difference between the mean mRS scores at 3 months after stroke among patients assigned clopidogrel compared with placebo (mean mRS 3.6 [SD 2.4] clopidogrel versus 3.3 [SD 2.1] placebo; P=0.15). There was also no significant difference between the various categories of the mRS score at 3 months after stroke among patients assigned to clopidogrel compared with placebo. Among 4320 patients with a qualifying diagnosis of transient ischemic attack or ischemic stroke, 233 (5.4%) experienced a stroke during follow-up, of whom 103 were randomly assigned clopidogrel and 130 placebo (relative risk reduction 20%, 95% CI: -3% to 38%). There was no significant difference between the mean mRS scores at 3 months after stroke among patients with a qualifying transient ischemic attack or ischemic stroke who were assigned clopidogrel compared with placebo (3.4 [SD 2.1] clopidogrel versus 3.3 [SD 1.9] placebo; P=0.48).
Conclusion-The addition of clopidogrel to acetylsalicylic acid did not significantly alter the rate and functional severity of stroke outcome events among high vascular risk patients enrolled in the CHARISMA trial. (Stroke. 2010;41:16791683.)

AB Background and Purpose-The purpose of this study was to determine whether acute diffusion-weighted imaging (DWI) and mean transit time (MTT) lesion volumes and presenting National Institutes of Health Stroke Scale (NIHSS) can identify patients with acute ischemic stroke who will have a high probability of good and poor outcomes.
Methods-Fifty-four patients with acute ischemic stroke who had MRI within 9 hours of symptom onset and 3-month follow-up with modified Rankin scale were evaluated. Acute DWI and MTT lesion volumes and baseline NIHSS scores were calculated. Clinical outcomes were considered good if the modified Rankin Scale was 0 to 2.
Results-The 33 of 54 (61%) patients with good outcomes had significantly smaller DWI lesion volumes (P=0.0001), smaller MTT lesion volumes (P < 0.0001), and lower NIHSS scores (P < 0.0001) compared with those with poor outcomes. Receiver operating characteristic curves for DWI, MTT, and NIHSS relative to poor outcome had areas under the curve of 0.889, 0.854, and 0.930, respectively, which were not significantly different. DWI and MTT lesion volumes predicted outcome better than mismatch volume or percentage mismatch. All patients with a DWI volume > 72 mL (13 of 54) and an NIHSS score > 20 (6 of 54) had poor outcomes. All patients with an MTT volume of < 47 mL (16 of 54) and an NIHSS score < 8 (17 of 54) had good outcomes. Combining clinical and imaging thresholds improved prognostic yield (70%) over clinical (43%) or imaging (54%) thresholds alone (P=0.01).
Conclusions-Combining quantitative DWI and MTT with NIHSS predicts good and poor outcomes with high probability and is superior to NIHSS alone. (Stroke. 2010;41:1728-1735.)

AB Background and Purpose-Nitric oxide mediates endothelium-dependent vasodilation, modulates cerebral blood flow, and determines stroke outcome. Nitric oxide signals in part by stimulating soluble guanylate cyclase (sGC) to synthesize cGMP. To study the role of sGC in stroke injury, we compared the outcome of cerebral ischemia and reperfusion in mice deficient in the alpha(1) subunit of sGC (sGC alpha(-/-)(1)) with that in wild-type mice.
Methods-Blood pressure, cerebrovascular anatomy, and vasoreactivity of pressurized carotid arteries were compared in both mouse genotypes. Cerebral blood flow was measured before and during middle cerebral artery occlusion and reperfusion. We then assessed neurological deficit and infarct volume after 1 hour of occlusion and 23 hours of reperfusion and after 24 hours of occlusion.
Results-Blood pressure and cerebrovascular anatomy were similar between genotypes. We found that vasodilation of carotid arteries in response to acetylcholine or sodium nitroprusside was diminished in sGC alpha(-/-)(1) compared with wild-type mice. Cerebral blood flow deficits did not differ between the genotypes during occlusion, but during reperfusion, cerebral blood flow was 45% less in sGC alpha(-/-)(1) mice. Infarct volumes and neurological deficits were similar after 24 hours of occlusion in both genotypes. After 1 hour of ischemia and 23 hours of reperfusion, infarct volumes were 2-fold larger and neurological deficits were worse in sGC alpha(-/-)(1) than in the wild-type mice.
Conclusion-sGC alpha(1) deficiency impairs vascular reactivity to nitric oxide and is associated with incomplete reperfusion, larger infarct size, and worse neurological damage, suggesting that cGMP generated by sGC alpha(1)beta(1) is protective in ischemic stroke. (Stroke. 2010; 41: 1815-1819.)

AB Background. Patients who undergo emergency operations represent a high-risk population and have been shown to have a high risk of poor outcomes Little Is known, however; about the variability in the quality of emergency general surgical care across hospitals or within hospitals across different procedures. The objectives of this study were to identify risk factors associated with. adverse events, to compare 30-day outcomes after 3 common emergency general surgery procedures within and across hospitals, and thus, to determine whether the quality of emergency surgical cam is procedure-dependent or intrinsic to oilier aspects of the hospital environment.
Methods. Patients who underwent emergency appendectomy, cholecystectomy, or colorectal resection at 95 hospitals that submitted at least 20 of each procedure were identified in the 2005-2008 American College of Surgeons National Surgical Quality Improvement Project database. Outcomes of interest included 30-day overall moridity and serious morbidity/mortality Step-wise logistic regression generated patient-level piedicted probabilities of an outcome. Based on the expected probabilities, observed to expected (O/E) ratios for each outcome, after each of the 3 procedures, were calculated for each hospital. Hospitals were divided into terciles based on O/E ratios. The agreement on hospital outcomes performance for overall morbidity and serious morbidity/mortality after appendectomy, cholecystectomy, and colorectal resection was assessed using weighted kappa statistics.
Results. Of the 30,788 appendectomies, 1,984 (6.44%) patients had any morbidity, and 1,140 (3 70%) patients had a serious morbidity or died Of the 5,824 cholecystectomies, 503 (8.64%) patients had any morbidity, and 371 (6.37%) patients had a serious morbidity or died Of the 8,990 colorectal resections, 4,202 (46 74%) patients had any morbidity, and 3,736 (41.56%) patients had a serious morbidity or died For overall morbidity, O/E ratios for appendectomy ranged from 0 26 to 2 36, O/E ratios for cholecystectomy ranged from 0 to 3.04, O/E ratios for colorectal resection ranged from. 0.45 to 1.51. For serious morbidity/mortality, O/E ratios for appendectomy ranged from 0.23 to 2.54; O/E ratios for choloystectomy ranged from 0 to 4 28, O/E ratios for colorectal resection ranged from 0.59 to 1.75 Associations of risk-adjusted hospital outcomes based on tercile rank between procedures demonstrated slight but significant agreement for both overall morbidity (weighted kappa between 0 20 and 0 22) and serious.morbidity/mortality (weighted kappa. bet won 0 18 and 0 22) Despite this, 7 (7.4%) hospitals for overall morbidity and 9 (9.5 %) hospitals for serious morbidity/modality were rated in the highest (best) tercile for all procedures. Eight (8.4%) hospitals for overall morbidity and 8 (8 4%) hospitals for serious.morbidity/mortality were rated in the lowest tercile for all procedures
Conclusion. Emergency general surgery procedures, particularly colorectal resections, were associated with substantial 30-day overall morbidity and serious morbidity/mortality. Most hospitals did not have consistent risk-adjusted outcomes across all 3 procedures, but for a substantive minority of institutions (7-10%), good or had performance was generalizable across procedures. Individual hospitals should examine then pocedure-specific outcomes after emergency general surge?), operations to focus quality improvement initiatives appropriately. (Singer), 2010;148.217-38.)

AB Background. We have recently demonstrated that treatment with suberoylanilide hydroxamic acid (SAHA), a histone deacetylase before a lethal dose of lipopolysaccharide (LPS) improves survival in mice The purpose of the present study was to determine whether SAHA treatment would attenuate LPS-induced shock and improve survival when given postinsult in a rodent model
Methods. C57BL/6J mice were intrapentoneally (IP) injected with LPS (30 mg/kg), and 2 hours later randomized into 2 groups. (1) vehicle animals (n = 10) received dimethyl sulfoxide (DMSO) solution only, and (2) SA HA animals (11 = 10) were given SA HA (50 mg/kg, IP) in DMSO solution. Survival was monitored over the next 7 days In a second study, LPS-injected mice were treated with either DMSO or SAHA as described, and normal (sham) animals served as controls Lungs were harvested at 4, 6, and 8 hours after LPS injection for analysts of gene expression In addition, RAW264.7 mouse macrophages were cultured to assess the effects of SAHA post-treatment on LPS-induced inflammation using enzyme-linked immunosorbent assay.
Results. All LPS-injected mice that received the vehicle agent alone died within 24 hours, whereas the SAHA-treated animals displayed a significant improvement in 1 week survival (80% vs 0%, P < .001) LPS insult significantly enhanced gene expression of MyD88, tumor necrosis factor (TNF)-alpha and interleukin (IL)-6, and was associated with an increased protein secretion of TXT-alpha and IL-6 into the cell culture medium. In contrast, SAHA treatment significantly attenuated all of these LPS-related alterations.
Conclusion. We report for the first time that administration of SAHA (50 mg/kg IP) after a lethal dose of LP,S significantly improves long-term survival, and attenuates expression of the proinflammatory mediators TAT-a and IL-6. Furthermore, our data suggest that the anti-inflammatory effects of,SA may be due to downregulation of the MyD88-dependent pathway, and decreased expression of associated proinflammatory genes (Surgery 2010:148:246-54.)

The role of routine hilar lymphadenectomy is controversial, but should be considered to optimize staging Although adjuvant chemotherapy and radiotherapy is probably not supported by current data, each should strongly be considered in patients with lymph node metastasis or an R1 resection. For those patients with inoperable disease, locoregional therapy with transarterial chemoembolization can be considered

AB The feasibility of transanal rectosigmoid resection with transanal endoscopic microsurgery (TEM) was previously demonstrated in a swine nonsurvival model in which transgastric endoscopic assistance also was shown to extend the length of colon mobilized transanally.
A 2-week survival study evaluating transanal endoscopic rectosigmoid resection with stapled colorectal anastomosis was conducted with swine using the transanal approach alone (TEM group, n = 10) or a transanal approach combined with transgastric endoscopic assistance (TEM + TG group, n = 10). Gastrotomies were created using a needleknife and balloon dilation, then closed using prototype T-tags. Outcomes were evaluated and compared between the groups using Student's t-test and Fisher's exact test.
Relative to the TEM group, the average length of rectosigmoid mobilized in the TEM + TG group was 15.6 versus 10.5 cm (p < 0.0005), the length of the resected specimen was 9 versus 6.2 cm (p < 0.0005), and the mean operative time was 254.5 versus 97.5 min (p < 0.0005). Intraoperatively, no organ injury or major bleeding was noted. Two T-tag misfires occurred during gastrotomy closure and four small staple line defects requiring transanal repair including one in the TEM group and three in the TEM + TG group (p = 0.2). Postoperatively, there was no mortality, and the animals gained an average of 3.4 lb. Two major complications (10%) were identified at necropsy in the TEM + TG group including an intraabdominal abscess and an abdominal wall hematoma related to T-tag misfire. Gastrotomy closure sites and colorectal anastomoses were all grossly healed, with adhesions noted in 60 and 70% and microabscesses in 50 and 20% of the gastrotomy sites and colorectal anastomoses, respectively.
Natural orifice translumenal endoscopic surgery (NOTES) for rectosigmoid resection using TEM with or without transgastric endoscopic assistance is feasible and associated with low morbidity in a porcine survival model. Transgastric assistance significantly prolongs the operative time but extends the length of the rectosigmoid mobilized transanally, with a nonsignificant increase in complication rates related to gastrotomy creation.

AB Publications of proton high resolution magic angle spinning (H-1 HRMAS) magnetic resonance spectroscopy (MRS) and its role in identification of metabolic markers for human cancer reported between 2005 and 2009 are reviewed according the anatomic sites of cancer: lung, breast, prostate, brain, colorectal, and cervical. Limited and insufficient screening options for the general public have indicated a need for more advanced tests that can identify and locate cancer at an early stage. H-1 HRMAS MRS is a valuable tool that can elucidate relevant biological metabolite information that is being used to distinguish cancer from benign tissue, and even classify types of tumors. Researchers are working to translate this ex vivo spectroscopy information into an in vivo system that could be implemented in cancer clinics. For instance, in the case of lung cancer, the goal is to identify the at risk population through a simple blood test, which would be the first level of screening. From these tests, patients identified as at risk will be able to undergo further non-invasive radiological testing for diagnostic purposes. Not only will this ex vivo technology become a valuable diagnostic tool, it will also provide a way to monitor treatments on an individual basis so they can be adjusted accordingly for the best possible outcome.

AB Background: The thyroidal response of pregnant patients with established Hashimoto's thyroiditis remains poorly described. The aim of this study was to determine the impact of pregnancy on Hashimoto's thyroiditis as revealed by changes in postpregnancy levothyroxine requirements.
Methods: We performed a retrospective study of 799 hypothyroid patients in a university hospital. We reviewed the clinical records and selected a group of well-documented pregnant (n = 34) and nonpregnant (n 32) hypothyroid women for study. We reviewed levothyroxine intake and serum thyrotropin (TSH) levels during three consecutive 9-month time intervals that were immediately before, during, and after pregnancy. We compared the percent change in levothyroxine dose between the prepregnancy level and each trimester during and after pregnancy.
Results: There were two patterns of levothyroxine supplementation during gestation. In pattern 1 (n 11) there was either no change or a single levothyroxine dose increase with no subsequent changes in each trimester (T1 = T2 = T3). In pattern 2 (n 18), multistep levothyroxine dose increases were required throughout pregnancy (T1< T2< T3) to maintain desired TSH levels (< 2.0 mU/L). Women with pattern 2 had mean TSH levels during gestation that differed significantly from pattern 1 (2.8 +/- 0.5 vs. 1.3 +/- 0.1 mU/L respectively; p<0.03). Further, in multivariate logistic regression, women with pattern 2 were 62 times more likely than women with pattern 1 to have a levothyroxine dose at least 20% above baseline at 3 months postpartum (p - 0.04).
Conclusions: We showed that >50% of hypothyroid women with Hashimoto's thyroiditis experienced an increase in levothyroxine requirements in the postpartum compared to pregestational doses. This pattern of enhanced levothyroxine need was most likely dependent on the preexisting thyroid functional reserve and postpartum progression of autoimmune destruction.

AB Objectives: Creating functional small-diameter tissue-engineered blood vessels has not been successful to date. Moreover, the processes underlying the in vivo remodeling of these grafts and the fate of cells seeded onto scaffolds remain unclear. Here we addressed these unmet scientific needs by using intravital molecular imaging to monitor the development of tissue-engineered vascular grafts (TEVG) implanted in mouse carotid artery.
Methods and Results: Green fluorescent protein-labeled human bone marrow-derived mesenchymal stem cells and cord blood-derived endothelial progenitor cells were seeded on polyglycolic acid-poly-L-lactic acid scaffolds to construct small-caliber TEVG that were subsequently implanted in the carotid artery position of nude mice (n = 9). Mice were injected with near-infrared agents and imaged using intravital fluorescence microscope at 0, 7, and 35 days to validate in vivo the TEVG remodeling capability (Prosense680; VisEn, Woburn, MA) and patency (Angiosense750; VisEn). Imaging coregistered strong proteolytic activity and blood flow through anastomoses at both 7 and 35 days postimplantation. In addition, image analyses showed green fluorescent protein signal produced from mesenchymal stem cell up to 35 days postimplantation. Comprehensive correlative histopathological analyses corroborated intravital imaging findings.
Conclusions: Multispectral imaging offers simultaneous characterization of in vivo remodeling enzyme activity, functionality, and cell fate of viable small-caliber TEVG.

AB The question of whether storage of red blood cells (RBCs) alters their capacity to deliver oxygen and affects patient outcomes remains in a state of clinical equipoise. Studies of the changes which occur while RBCs are stored have led to several physiologically plausible hypotheses that these changes impair RBC function when the units are transfused. Although there is some evidence of this effect in vivo from animal model experiments, the results of several largely retrospective patient studies have not been consistent. Some studies have shown an association between worse clinical outcomes and transfusion of RBC which have been stored for longer periods of time, while others have found no effect. Three multicenter, randomized, controlled trials have been developed to address this important, but currently unanswered, question. Two clinical trials, one in low birth weight neonates and the other in intensive care unit patients, are enrolling subjects in Canada (the Age of Red Blood Cells in Premature Infants; the Age of Blood Study). The third trial, which is being developed in the United States, is the Red Cell Storage Duration Study (RECESS). This is a multicenter, randomized, controlled trial in which patients undergoing complex cardiac surgical procedures who are likely to require RBC transfusion will be randomized to receive RBC units stored for either 10 or fewer days or 21 or more days. Randomization will only occur if the blood bank has enough units of RBC of both storage times to meet the crossmatch request; hence, subjects randomized to the >= 21 day arm will receive RBC of the same storage time as they would have following standard inventory practice of "oldest units out first". The primary outcome is the change in the Multiple Organ Dysfunction Score (MODS), a composite measure of multiorgan dysfunction, by day 7. Secondary outcomes include the change in the MODS by day 28, all-cause mortality, and several composite and single measures of specific organ system function. The estimated total sample size required will be 1434 evaluable subjects (717 per arm). The RECESS trial is registered through the US National Institutes of Health (clinicaltrials.gov) as NCT00991341. Crown Copyright (C) 2010 Published by Elsevier Ltd. All rights reserved.

AB Bacillus Calmette-Guerin (BCG) exerts its antitumor activity through induction of pro-inflammatory cytokines, while immunosuppressive agents prevent organ rejection by suppressing pro-inflammatory and promoting anti-inflammatory responses. Thus, in the setting of transplant populations, the use of intravesical BCG for bladder cancer has the possibility of either promoting allograft rejection or being rendered ineffective by the action of immunosuppressive agents that block pro-inflammatory responses. We discuss the potential immunologic interactions between BCG and immunosuppression, and review relevant outcomes in renal transplant recipients with bladder cancer receiving intravesical BCG.

AB Spatiotemporal characterization of protein protein interactions (PPIs) is essential in determining the molecular mechanisms of intracellular signaling processes. In this review, we discuss how new methodological strategies derived from non-invasive fluorescence- and luminescence-based approaches (FRET, BRET, BiFC and BiLC), when applied to the study of G protein-coupled receptor (GPCR) oligomerization, can be used to detect specific PPIs in live cells. These technologies alone or in concert with complementary methods (SRET, BRET or BiFC, and SNAP-tag or TR-FRET) can be extremely powerful approaches for PPI visualization, even between more than two proteins. Here we provide a comprehensive update on all the biotechnological aspects, including the strengths and weaknesses, of new fluorescence- and luminescence-based methodologies, with a specific focus on their application for studying PPIs.

AB The long-standing model for hematopoiesis, which features a dichotomy into separate lymphoid and myeloid branches, predicts that progenitor T cells arise from a lymphocyte-restricted pathway. However, experiments that have detected myeloid potential in progenitor T cells have been reported as evidence to question this model. Mapping physiological differentiation pathways has now led to opposite conclusions, by showing that T cells and thymic myeloid cells have distinct origins and that, in vivo, T cell progenitors lack significant potential for myeloid lineages including dendritic cells. Here, we review the underlying experiments that have led to such fundamentally different conclusions. The current controversy might reflect a need to distinguish between cell fates that are possible experimentally from physiological fate choices, to build a map of immunological differentiation pathways.

AB Point-of-care ultrasound is being increasingly implemented in resource-poor settings in an ad hoc fashion. We developed a focused maternal ultrasound-training program for midwives in a rural health district in Zambia. Four hundred forty-one scans were recorded by 21 midwives during the 6-month study period. In 74 scans (17%), the ultrasound findings prompted a change in clinical decision-making. Eight of the midwives were evaluated with a 14-question observed structured clinical examination (OSCE) and demonstrated a slight overall improvement with mean scores at 2 and 6 months of 10.0/14 (71%) and 11.6/14 (83%), respectively. Our pilot project demonstrates that midwives in rural Zambia can be trained to perform basic obstetric ultrasound and that it impacts clinical decision-making. Ultrasound skills were retained over the study period. More data is necessary to determine whether the introduction of ultrasound ultimately improves outcomes of pregnant women in rural Zambia.

AB The distinction between oncocytoma and chromophobe renal cell carcinoma, important clinically, may be challenging, especially as the tissue sample size decreases. Ancillary studies can be helpful, although subject to interpretation and sample variability. The aim of this study was to examine the value of electron microscopy in differentiating between oncocytoma and chromophobe renal cell carcinoma on formalin fixed paraffin embedded needle core biopsies. Twenty renal needle core biopsies were evaluated. Despite formalin fixation and paraffin embedding, the classic ultrastructural features of these neoplasms were retained, revealing 80% sensitivity and 100% specificity by initial work-up.

AB OBJECTIVES To describe the practice patterns among primary care physicians' (PCPs) managing patients with symptoms suggestive of interstitial cystitis/painful bladder syndrome (IC/PBS).
METHODS We developed a clinical vignette describing a woman with typical IC/PBS symptoms to elicit questions about etiology, management strategies, and familiarity with this syndrome. We mailed the questionnaire to 556 PCPs, including academicians and community physicians, in Boston, Los Angeles, and Chicago.
RESULTS We received 290 completed questionnaires (response rate, 52%). Nineteen percent of respondents reported they had "never" seen a patient like the one described in the vignette. Two-thirds of respondents correctly identified the hallmark symptom of IC/PBS (bladder pain/pressure). Regarding etiology, 90% correctly indicated that IC/PBS was a noninfectious disease, 76% correctly reported that it was not caused by a sexually transmitted infection, and 61% correctly indicated that it was not caused by a psychiatric illness. Common treatments included antibiotics and nonsteroidal anti-inflammatory agents. Referrals were often made to a specialist.
CONCLUSIONS Although most PCPs indicate familiarity with IC/PBS, they manage the condition infrequently. They also appear to have significant knowledge deficits about the clinical characteristics of IC/PBS, and they indicate variable practice patterns in the diagnosis and treatment of the condition. Educational efforts directed at PCPs will likely improve the care of patients with IC/PBS. UROLOGY 76: 323-329, 2010. (C) 2010 Elsevier Inc. All rights reserved.

AB OBJECTIVES To characterize and evaluate the efficacy of second-line therapy in patients who had progressed on initial anti-vascular endothelial growth factor (VEGF) therapy.
METHODS Between 2005 and 2007, patients with mRCC who received second-line therapy after 1st-line VEGF-targeted therapy were identified across 7 cancer centers.
RESULTS A total of 645 mRCC patients received first-line VEGF-targeted therapy, of which 216 patients received second-line VEGF-targeted therapy (sunitinib, n = 93; sorafenib, n = 80; bevacizumab, n = 11; axitinib, n = 8) or mammalian target of rapamycin (mTOR)-inhibiting agents (temsirolimus, n = 21; everolimus, n = 3). On multivariate analysis, a higher baseline Karnofsky performance status score before first-line therapy predicted which patients were more likely to receive second-line therapy (P < .0001). The median time to treatment failure of second-line therapy was 4.9 months for anti-VEGF therapy and 2.5 months for mTOR inhibitors (P = .014) (HR: 0.52, CI: 0.29-0.91 and HR: 0.495, CI: 0.27-0.9 after adjusting for Memorial Sloan-Kettering Cancer Center prognostic factors and histology, respectively). Overall survival from start of second-line therapy was not significantly different (14.2 vs 10.6 months respectively; P = .38).
CONCLUSIONS Baseline Karnofsky performance status is an independent predictor of receiving second-line targeted therapy. Patients who receive a second-line anti-VEGF drug appear to have a similar overall survival to those who receive a second-line anti-mTOR drug. UROLOGY 76: 430-435, 2010. (C) 2010 Elsevier Inc.

AB Cardiovascular event rates have been shown to increase substantially with the number of symptomatic disease locations. We sought to assess the risk profile, management and subsequent event rates of polyvascular disease patients. Consecutive outpatients were assessed for atherosclerotic risk factors and medications in the REACH Registry. A total of 19,117 symptomatic patients in Europe completed a 2-year follow-up: 77.2% with single arterial bed disease (coronary artery or cerebrovascular or peripheral arterial disease) and 22.8% with polyvascular disease (>= 1 disease location). Polyvascular disease patients were older (68.5 +/- 9.4 vs 66.3 +/- 9.9 years, p < 0.0001), more often current or former smokers (64.9% vs 58.7%, p < 0.0001), and more often suffered from hypertension (59.5% vs 46.6%, p < 0.0001) and diabetes (34.5% vs 25.9%, p < 0.0001) than single arterial bed disease patients. Despite more intense medical therapy, risk factors (smoking, hypertension, low fasting glucose, and low fasting total cholesterol) were less often controlled in polyvascular disease patients. This was associated with substantially more events over 2 years compared with single arterial bed disease patients (cMACCE [cardiovascular death/non-fatal stroke/non-fatal MI] odds ratio, 1.63 [95% CI, 1.45-1.83], p < 0.0001). In conclusion, polyvascular disease patients have more cardiovascular risk factors, and the prognosis for these patients is significantly worse than for patients with single arterial bed disease. This suggests a need to improve detection and consequent medical treatment of polyvascular disease.

AB Aim: The aims of this review were to discuss the different mechanisms of biocorrosion of orthopaedic metal implants in the human body, as well as the effects of the released metal ions on bone metabolism and the immune system in regard to their involvement in the pathophysiological mechanisms of aseptic loosening and metal hypersensitivity. Implant failure due to aseptic loosening is thought to occur in about 10-15% of cases.
Methods: A review of the literature (using PubMed with the search terms: biocorrosion, metal ions and bone metabolism) was performed. Additionally, we discuss our research results in the field of aseptic loosening.
Results: Despite a great effort in developing new implants, metal devices used in orthopaedic and trauma surgery remain prone to biocorrosion by several mechanisms including the direct corrosion by osteoclasts, leading to the production of significant amounts of wear particles and metal ions. In addition to the well documented increased osteolytic activity caused by large (in the nanometer range) wear particles, increasing evidence strongly suggests that the released metal ions contribute to the pathophysiological mechanism of aseptic loosening. Metal ions stimulate both the immune system and bone metabolism through a series of direct and indirect pathways leading to an increased osteolytic activity at the bone-implant interface.
Conclusion: To date, revision surgery remains the only option for the treatment of a failed orthopaedic implant caused by aseptic loosening. A better understanding of the complex pathophysiological mechanisms (including the effects caused by the released metal ions) of aseptic loosening may have a significant potential in developing novel implants and therapies in order to reduce the incidence of this complication.

AB Objective: To inform guidelines concerning when to initiate combination antiretroviral therapy (ART), we investigated whether CD4(+) T-cell counts (CD4 cell counts) continue to increase over long periods of time on ART. Losses-to-follow-up and some patients discontinuing ART at higher CD4 cell counts hamper such evaluation, but novel statistical methods can help address these issues. We estimated the long-term CD4 cell count trajectory accounting for losses-to-follow-up and treatment discontinuations.
Design: The study population included 898 US patients first initiating ART in a randomized trial (AIDS Clinical Trials Group 384); 575 were subsequently prospectively followed in an observational study (AIDS Clinical Trials Group Longitudinal Linked Randomized Trials).
Methods: Inverse probability of censoring weighting statistical methods were used to estimate the CD4 cell count trajectory accounting for losses-to-follow-up and ART discontinuations, overall and for pretreatment CD4 cell count categories (<= 200, 201-350, 351-500, and > 500 cells/mu l).
Results: Median CD4 cell count increased from 270 cells/mu l pre-ART to an estimated 556 cells/mu l at 3 and 532 cells/mu l at 7 years after starting ART in analyses ignoring treatment discontinuations, and to 570 and 640 cells/mu l, respectively, had all patients continuedART. However, even hadARTbeen continued, an estimated 25, 9, 3, and2% of patients with pretreatment CD4 cell counts of 200 or less, 201 -350, 351 -500, and more than 500 cells/mu l would have had CD4 cell counts of 350 cells/mu l or less after 7 years.
Conclusion: If patients remain on ART, CD4 cell counts increase in most patients for at least 7 years. However, the substantial percentage of patients starting therapy at low CD4 cell counts who still had low CD4 cell counts after 7 years provides support for ART initiation at higher CD4 cell counts.

AB Telomerase activity in HIV-1-specific CD8(+) T cells from controllers contributes to the maintenance of highly functional cytotoxic T cell responses against HIV-1. Here, we show that high expression of telomerase in controllers is associated with hypermethylation at the distal and hypomethylation at the proximal human telomerase catalytic subunit promoter, whereas HIV-1-specific CD8(+) T cells from progressors showed an inverse pattern with distal promoter hypomethylation and proximal promoter hypermethylation. These data suggest distinct epigenetic signatures in HIV-1-specific T cells in progressors and controllers.

AB Dynamic histone H3K4 methylation is an important epigenetic component of transcriptional regulation. However, most of our current understanding of this histone mark is confined to the regulation of transcriptional initiation. We now show that human LSD2/KDM1b/AOF1, the human homolog of LSD1, is an H3K4me1/2 demethylase that specifically regulates histone H3K4 methylation within intragenic regions of its target genes. Genome-wide mapping reveals that LSD2 associates predominantly with the gene bodies of actively transcribed genes, but is markedly absent from promoters. Depletion of endogenous LSD2 results in an increase of H3K4me2 as well as a decrease of H3K9me2 at LSD2-binding sites and a consequent dysregulation of target gene transcription. Furthermore, characterization of the LSD2 complex reveals that LSD2 forms active complexes with euchromatic histone methyltransferases G9a and NSD3 as well as cellular factors involved in transcription elongation. These data provide a possible molecular mechanism linking LSD2 to transcriptional regulation after initiation.

AB Cells from Fanconi anemia (FA) patients are extremely sensitive to DNA interstrand crosslinking (ICL) agents, but the molecular basis of the hypersensitivity remains to be explored. FANCM (FA complementation group M), and its binding partner, FAAP24, anchor the multisubunit FA core complex to chromatin after DNA damage and may contribute to ICL-specific cellular response. Here we show that the FANCM/FAAP24 complex is specifically required for the recruitment of replication protein A (RPA) to ICL-stalled replication forks. ICL-induced RPA foci formation requires the DNA-binding activity of FAAP24 but not the DNA translocase activity of FANCM. Furthermore, FANCM/FAAP24-dependent RPA foci formation is required for efficient ATR-mediated checkpoint activation in response to ICL. Therefore, we propose that FANCM/FAAP24 plays a role in ICL-induced checkpoint activation through regulating RPA recruiment at ICL-stalled replication forks.

AB Background: The cellular and molecular programs that control specific types of pain are poorly understood. We reported previously that the runt domain transcription factor Runx1 is initially expressed in most nociceptors and controls sensory neuron phenotypes necessary for inflammatory and neuropathic pain.
Results: Here we show that expression of Runx1-dependent ion channels and receptors is distributed into two nociceptor populations that are distinguished by persistent or transient Runx1 expression. Conditional mutation of Runx1 at perinatal stages leads to preferential impairment of Runx1-persistent nociceptors and a selective defect in inflammatory pain. Conversely, constitutive Runx1 expression in Runx1-transient nociceptors leads to an impairment of Runx1-transient nociceptors and a selective deficit in neuropathic pain. Notably, the subdivision of Runx1-persistent and Runx1-transient nociceptors does not follow the classical nociceptor subdivision into IB4(+) nonpeptidergic and IB4(-) peptidergic populations.
Conclusion: Altogether, we have uncovered two distinct Runx1-dependent nociceptor differentiation programs that are permissive for inflammatory versus neuropathic pain. These studies lend support to a transcription factor-based distinction of neuronal classes necessary for inflammatory versus neuropathic pain.

AB The parkinsonian syndromes comprise a highly heterogeneous group of disorders. Although 15 loci are linked to predominantly familial Parkinson's disease (PD), additional PD loci are likely to exist. We recently identified a multigenerational family of Danish and German descent in which five males in three generations presented with a unique syndrome characterized by parkinsonian features and variably penetrant spasticity for which X-linked disease transmission was strongly suggested (XPDS). Autopsy in one individual failed to reveal synucleinopathy; however, there was a significant four-repeat tauopathy in the striatum. Our objective was to identify the locus responsible for this unique parkinsonian disorder. Members of the XPDS family were genotyped for markers spanning the X chromosome. Two-point and multipoint linkage analyses were performed and the candidate region refined by analyzing additional markers. A multipoint LOD(max) score of 2.068 was obtained between markers DXS991 and DXS993. Haplotype examination revealed an similar to 20 cM region bounded by markers DXS8042 and DXS1216 that segregated with disease in all affected males and obligate carrier females and was not carried by unaffected at-risk males. To reduce the possibility of a false-positive linkage result, multiple loci and genes associated with other parkinsonian or spasticity syndromes were excluded. In conclusion, we have identified a unique X-linked parkinsonian syndrome with variable spasticity and four-repeat tau pathology, and defined a novel candidate gene locus spanning similar to 28 Mb from Xp11.2-Xq13.3.

AB Background: The scientific basis for acupuncture meridians is unknown. Past studies have suggested that acupuncture meridians are physiologically characterized by low electrical impedance and anatomically associated with connective tissue planes. We are interested in seeing whether acupuncture meridians are associated with lower electrical impedance and whether ultrasound-derived measures-specifically echogenic collagenous bands - can account for these impedance differences.
Methods/Results: In 28 healthy subjects, we assessed electrical impedance of skin and underlying subcutaneous connective tissue using a four needle-electrode approach. The impedances were obtained at 10 kHz and 100 kHz frequencies and at three body sites - upper arm (Large Intestine meridian), thigh (Liver), and lower leg (Bladder). Meridian locations were determined by acupuncturists. Ultrasound images were obtained to characterize the anatomical features at each measured site. We found significantly reduced electrical impedance at the Large Intestine meridian compared to adjacent control for both frequencies. No significant decrease in impedance was found at the Liver or Bladder meridian. Greater subcutaneous echogenic densities were significantly associated with reduced impedances in both within-site (meridian vs. adjacent control) and between-site (arm vs. thigh vs. lower leg) analyses. This relationship remained significant in multivariable analyses which also accounted for gender, needle penetration depth, subcutaneous layer thickness, and other ultrasound-derived measures.
Conclusion/Significance: Collagenous bands, represented by increased ultrasound echogenicity, are significantly associated with lower electrical impedance and may account for reduced impedances previously reported at acupuncture meridians. This finding may provide important insights into the nature of acupuncture meridians and the relevance of collagen in bioelectrical measurements.

AB Thermal injury triggers a fulminant inflammatory cascade that heralds shock, end-organ failure, and ultimately sepsis and death. Emerging evidence points to a critical role for the innate immune system, and several studies had documented concurrent impairment in neutrophil chemotaxis with these post-burn inflammatory changes. While a few studies suggest that a link between neutrophil motility and patient mortality might exist, so far, cumbersome assays have prohibited exploration of the prognostic and diagnostic significance of chemotaxis after burn injury. To address this need, we developed a microfluidic device that is simple to operate and allows for precise and robust measurements of chemotaxis speed and persistence characteristics at single-cell resolution. Using this assay, we established a reference set of migration speed values for neutrophils from healthy subjects. Comparisons with samples from burn patients revealed impaired directional migration speed starting as early as 24 hours after burn injury, reaching a minimum at 72-120 hours, correlated to the size of the burn injury and potentially serving as an early indicator for concurrent infections. Further characterization of neutrophil chemotaxis using this new assay may have important diagnostic implications not only for burn patients but also for patients afflicted by other diseases that compromise neutrophil functions.

AB Histone deacetylases (HDACs) are pivotal enzymes in the epigenetic modification or regulatory mechanisms of gene transcription. Based on previous assertions that the pathophysiology of schizophrenia is associated with epigenetics, we hypothesized that polymorphisms of HDAC genes might be related to schizophrenia. We recruited 278 patients with schizophrenia and 234 normal controls from a Korean population. Clinical information of the group with schizophrenia was obtained from medical records, the Brief Psychiatric Rating Scale (BPRS), the Scale for the Assessment of Negative Symptoms (SANS), and the Operational Criteria Checklist (OPCRIT). Three single-nucleotide polymorphisms (SNFs) in HDAC genes were selected, including rs2530223 of HDAC3, rs1063639 of HDAC4. and rs1555048 of HDAC10. For the analysis of genetic data, SNPStats. SNPAnalyzer, and Helixtree programs were used. In the present study, rs1063639 of the HDAC4 gene showed associations with schizophrenia in the codominant and dominant models. In the analysis of clinical phenotypes, smoking status was associated with rs2530223 of HDAC3 in the codominant and recessive models. The results suggest that HDAC3 and HDAC4 genes might play a role in the pathophysiology of schizophrenia in a Korean population. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

AB The cerebral white matter (WM) is critically involved in many bio-behavioral functions impaired in schizophrenia. However, the specific neural systems underlying symptomatology in schizophrenia are not well known. By comparing the volume of all brain fiber systems between chronic patients with DSM-III-R schizophrenia (n = 88) and matched healthy community controls (n = 40), we found that a set of a priori WM regions of local and distal associative fiber systems was significantly different in patients with schizophrenia. There were significant positive correlations between volumes (larger) in anterior callosal, cingulate and temporal deep WM regions (related to distal connections) with positive symptoms, such as hallucinations, delusions and bizarre behavior, and significant negative correlation between volumes (smaller) in occipital and paralimbic superficial WM (related to local connections) and posterior callosal fiber systems with higher negative symptoms, such as alogia. Furthermore, the temporal sagittal system showed significant rightward asymmetry between patients and controls. These observations suggest a pattern of volume WM alterations associated with symptomatology in schizophrenia that may be related in part to predisposition to schizophrenia.

AB Using a combination high-throughput screening technology, multiple classes of drugs and targeted agents were identified that synergize with dexamethasone (Dex) in multiple myeloma (MM) cells. Performing combination screening with these enhancers, we discovered an unexpected synergistic interaction between adenosine receptor agonists and phosphodiesterase (PDE) inhibitors that displays substantial activity in a panel of MM and diffuse large B-cell lymphoma (DLBCL) cell lines and tumor cells from MM patients. We have used selective adenosine receptor agonists, antagonists, and PDE inhibitors as well as small interfering RNAs targeting specific molecular isoforms of these proteins to dissect the molecular mechanism of this synergy. The adenosine A2A receptor and PDE2, 3, 4, and 7 are important for activity. Drug combinations induce cyclic AMP (cAMP) accumulation and up-regulate PDE4B. We also observe rigorous mathematical synergy in 3-way combinations containing A2A agonists, PDE inhibitors, and Dex at multiple concentrations and ratios. Taken together, these data suggest that A2A agonist/PDE inhibitor combinations may be attractive as an adjunctive to clinical glucocorticoid containing regiments for patients with MM or DLBCL and confer benefit in both glucocorticoid-sensitive and -resistant populations.

AB This review focuses on mechanisms and emerging concepts that drive the science of stroke in a therapeutic direction. Once considered exclusively a disorder of blood vessels, growing evidence has led to the realization that the biological processes underlying stroke are driven by the interaction of neurons, glia, vascular cells, and matrix components, which actively participate in mechanisms of tissue injury and repair. As new targets are identified, new opportunities emerge that build on an appreciation of acute cellular events acting in a broader context of ongoing destructive, protective, and reparative processes. The burden of disease is great, and its magnitude widens as a role for blood vessels and stroke in vascular and nonvascular dementias becomes more clearly established. This review then poses a number of fundamental questions, the answers to which may generate new directions for research and possibly new treatments that could reduce the impact of this enormous economic and societal burden.

AB Background: Sipuleucel-T, an autologous active cellular immunotherapy, has shown evidence of efficacy in reducing the risk of death among men with metastatic castration-resistant prostate cancer.
Methods: In this double-blind, placebo-controlled, multicenter phase 3 trial, we randomly assigned 512 patients in a 2:1 ratio to receive either sipuleucel-T (341 patients) or placebo (171 patients) administered intravenously every 2 weeks, for a total of three infusions. The primary end point was overall survival, analyzed by means of a stratified Cox regression model adjusted for baseline levels of serum prostate-specific antigen (PSA) and lactate dehydrogenase.
Results: In the sipuleucel-T group, there was a relative reduction of 22% in the risk of death as compared with the placebo group (hazard ratio, 0.78; 95% confidence interval [CI], 0.61 to 0.98; P=0.03). This reduction represented a 4.1-month improvement in median survival (25.8 months in the sipuleucel-T group vs. 21.7 months in the placebo group). The 36-month survival probability was 31.7% in the sipuleucel-T group versus 23.0% in the placebo group. The treatment effect was also observed with the use of an unadjusted Cox model and a log-rank test (hazard ratio, 0.77; 95% CI, 0.61 to 0.97; P=0.02) and after adjustment for use of docetaxel after the study therapy (hazard ratio, 0.78; 95% CI, 0.62 to 0.98; P=0.03). The time to objective disease progression was similar in the two study groups. Immune responses to the immunizing antigen were observed in patients who received sipuleucel-T. Adverse events that were more frequently reported in the sipuleucel-T group than in the placebo group included chills, fever, and headache.
Conclusions: The use of sipuleucel-T prolonged overall survival among men with metastatic castration-resistant prostate cancer. No effect on the time to disease progression was observed. (Funded by Dendreon; ClinicalTrials.gov number, NCT00065442.)

TI Establishment of Protein Delivery Systems Targeting Podocytes
SO PLOS ONE
LA English
DT Article
ID FOCAL SEGMENTAL GLOMERULOSCLEROSIS; GLOMERULAR PROTEIN; NEPHROTIC
SYNDROME; TRPC6; CELLS
AB Background: Podocytes are uniquely structured cells that are critical to the kidney filtration barrier. Their anatomic location on the outer side of the glomerular capillaries expose podocytes to large quantities of both plasma and urinary components and thus are reachable for drug delivery. Recent years have made clear that interference with podocyte-specific disease pathways can modulate glomerular function and influence severity and progression of glomerular disease.
Methodology/Principal Findings: Here, we describe studies that show efficient transport of proteins into the mammalian cells mouse 3T3 fibroblasts and podocytes, utilizing an approach termed profection. We are using synthetic lipid structures that allow the safe packing of proteins or antibodies resulting in the subsequent delivery of protein into the cell. The uptake of lipid coated protein is facilitated by the intrinsic characteristic of cells such as podocytes to engulf particles that are physiologically retained in the extracellular matrix. Profection of the restriction enzyme MunI in 3T3 mouse fibroblasts caused an increase in DNA degradation. Moreover, purified proteins such as beta-galactosidase and the large GTPase dynamin could be profected into podocytes using two different profection reagents with the success rate of 95-100%. The delivered b-galactosidase enzyme was properly folded and able to cleave its substrate X-gal in podocytes. Diseased podocytes are also potential recipients of protein cargo as we also delivered fluorophore labeled IgG into puromycin treated podocytes. We are currently optimizing our protocol for in vivo profection.
Conclusions: Protein transfer is developing as an exciting tool to study and target highly differentiated cells such as podocytes.

AB We describe an optimized systematic screen of known kinases using osteosarcoma cell lines (KHOS and U-2OS) and a lentiviral-based short hairpin RNA (shRNA) human kinase library. CellTiter 96 (R) AQueous One Solution Cell Proliferation Assay was used to measure cell growth and survival. We identified several kinases, including human polo-like kinase (PLK1), which inhibit cell growth and induce apoptosis in osteosarcoma cells when knocked down. cDNA rescue and synthetic siRNA assays confirm that the observed phenotypic changes result from the loss of PLK1 gene expression.
Furthermore, a small molecule inhibitor to PLK1 inhibited osteosarcoma cell growth and induced apoptosis. Western blot analysis confirmed that PLK1 is highly expressed and activated in several osteosarcoma cell lines as well as in resected tumor samples. Immunohistochemistry analysis showed that patients with high PLK1 tumor expression levels correlated with significantly shorter survival than patients with lower levels of tumor PLK1 expression. These results demonstrate the capability and feasibility of a high-throughput screen with a large collection of lentiviral kinases and its effectiveness in identifying potential drug targets. The development of more potent inhibitors that target PLK1 may open doors to a new range of anti-cancer strategies in osteosarcoma. (C) 2010 Elsevier Ireland Ltd. All rights reserved.

AB Tumor Necrosis Factor-a Related Apoptosis Inducing Ligand (TRAIL) and agonistic antibodies to death receptors (DR) 4 and 5 have attracted significant attention in recent years due to their ability to selectively induce apoptosis in malignant cells while demonstrating little cytotoxicity in normal cells. Although these candidates are promising in cancer therapy, a number of tumor cells are resistant to TRAIL-mediated apoptosis. We describe the use of a cationic amphipathic lytic peptide, KLA (single letter sequence HHHHHKLAK-LAKKLAKLAKC), for the chemosensitization of TRAIL-resistant LNCaP and PC3-PSMA human prostate cancer cells to DR agonistic antibodies. 'Single-agent' treatment with DR agonistic antibodies did not result in loss of viability of these cells confirming the resistance of these cells. However, the combination treatment of KLA followed by DR agonists resulted in greater cell death compared to the individual treatments acting alone, indicating synergistic action between the two components of the combination treatment. The combination of lytic peptide and DR agonists resulted in a significant increase in activated caspase-3 cleavage and cytochrome-C protein levels in cells, indicating a role for the caspase-mediated apoptotic pathway. In addition, KLA treatment also resulted in increased localization of DR5 and lipid rafts in LNCaP cells. Our results demonstrate, for the first time, that lytic peptides can be employed for sensitizing TRAIL-resistant prostate cancer cells to DR-mediated apoptosis resulting in novel combination treatments for the ablation of advanced cancer cells.

AB Context A variety of topical and systemic drugs are available to treat primary Sjogren syndrome, although no evidence-based therapeutic guidelines are currently available.
Objective To summarize evidence on primary Sjogren syndrome drug therapy from randomized controlled trials.
Data Sources We searched MEDLINE and EMBASE for articles on drug therapy for primary Sjogren syndrome published between January 1, 1986, and April 30, 2010.
Study Selection Controlled trials of topical and systemic drugs including adult patients with primary Sjogren syndrome were selected as the primary information source.
Results The search strategy yielded 37 trials. A placebo-controlled trial found significant improvement in the Schirmer and corneal staining scores, blurred vision, and artificial tear use in patients treated with topical ocular 0.05% cyclosporine. Three placebo-controlled trials found that pilocarpine was associated with improvements in dry mouth (61%-70% vs 24%-31% in the placebo group) and dry eye (42%-53% vs 26%). Two placebo-controlled trials found that cevimeline was associated with improvement in dry mouth (66%-76% vs 35%-37% in the placebo group) and dry eye (39%-72% vs 24%-30%). Small trials (<20 patients) found no significant improvement in sicca outcomes for oral prednisone or hydroxychloroquine and limited benefits for immunosuppressive agents (azathioprine and cyclosporine). A large trial found limited benefits for oral interferon alfa-2a. Two placebo-controlled trials of infliximab and etanercept did not achieve the primary outcome (a composite visual analog scale measuring joint pain, fatigue, and dryness); neither did 2 small trials (<30 patients) testing rituximab, although significant results were observed in some secondary outcomes and improvement compared with baseline.
Conclusions In primary Sjogren syndrome, evidence from controlled trials suggests benefits for pilocarpine and cevimeline for sicca features and topical cyclosporine for moderate or severe dry eye. Anti-tumor necrosis factor agents have not shown clinical efficacy, and larger controlled trials are needed to establish the efficacy of rituximab. JAMA. 2010; 304(4): 452-460

AB Epileptic seizures reflect a pathological brain state characterized by specific clinical and electrical manifestations. The proposed mechanisms are heterogeneous but united by the supposition that epileptic activity is hypersynchronous across multiple scales, yet principled and quantitative analyses of seizure dynamics across space and throughout the entire ictal period are rare. To more completely explore spatiotemporal interactions during seizures, we examined electrocorticogram data from a population of male and female human patients with epilepsy and from these data constructed dynamic network representations using statistically robust measures. We found that these networks evolved through a distinct topological progression during the seizure. Surprisingly, the overall synchronization changed only weakly, whereas the topology changed dramatically in organization. A large subnetwork dominated the network architecture at seizure onset and preceding termination but, between, fractured into smaller groups. Common network characteristics appeared consistently for a population of subjects, and, for each subject, similar networks appeared from seizure to seizure. These results suggest that, at the macroscopic spatial scale, epilepsy is not so much a manifestation of hypersynchrony but instead of network reorganization.

AB Background-Clinic-based observational studies in men have reported that obstructive sleep apnea is associated with an increased incidence of coronary heart disease. The objective of this study was to assess the relation of obstructive sleep apnea to incident coronary heart disease and heart failure in a general community sample of adult men and women.
Methods and Results-A total of 1927 men and 2495 women >= 40 years of age and free of coronary heart disease and heart failure at the time of baseline polysomnography were followed up for a median of 8.7 years in this prospective longitudinal epidemiological study. After adjustment for multiple risk factors, obstructive sleep apnea was a significant predictor of incident coronary heart disease (myocardial infarction, revascularization procedure, or coronary heart disease death) only in men <= 70 years of age (adjusted hazard ratio 1.10 [95% confidence interval 1.00 to 1.21] per 10-unit increase in apnea-hypopnea index [AHI]) but not in older men or in women of any age. Among men 40 to 70 years old, those with AHI >= 30 were 68% more likely to develop coronary heart disease than those with AHI <5. Obstructive sleep apnea predicted incident heart failure in men but not in women (adjusted hazard ratio 1.13 [95% confidence interval 1.02 to 1.26] per 10-unit increase in AHI). Men with AHI >= 30 were 58% more likely to develop heart failure than those with AHI <5.
Conclusions-Obstructive sleep apnea is associated with an increased risk of incident heart failure in communitydwelling middle- aged and older men; its association with incident coronary heart disease in this sample is equivocal. (Circulation. 2010; 122:352-360.)

AB This paper details the substance and recommendations arising from a meeting convened by the National Heart, Lung, and Blood Institute in August 2009, to assess the challenges and opportunities of emergency department management of acute heart failure syndrome (AHFS). The assembled faculty represented a large cross section of medical professionals spanning the medical management continuum of patients presenting with acute heart failure and included heart failure cardiologists, emergency physicians, laboratory medicine specialists, nurses, and bench scientists. Their recommendations include proposals regarding the design and conduct of emergency department-based clinical trials, suggestions regarding the development of improved methods for early detection and monitoring of AHFS, and potential needs for expanding translational and applied AHFS focused research and biotechnology. We anticipate that this review will serve as a starting point for future investigations across the spectrum of funding sources.

AB Objectives This study sought to determine recent trends over time in heart failure hospitalization, patient characteristics, treatment, rehospitalization, and mortality within the Veterans Affairs health care system.
Background Use of recommended therapies for heart failure has increased in the U.S. However, it is unclear to what extent hospitalization rates and the associated mortality have improved.
Methods We compared rates of hospitalization for heart failure, 30-day rehospitalization for heart failure, and 30-day mortality following discharge from 2002 to 2006 in the Veterans Affairs Health Care System. Odds ratios for outcome were adjusted for patient diagnoses within the past year, laboratory data, and for clustering of patients within hospitals.
Results We identified 50,125 patients with a first hospitalization for heart failure from 2002 to 2006. Mean age did not change (70 years), but increases were noted for most comorbidities (mean Charlson score increased from 1.72 to 1.89, p < 0.0001). Heart failure admission rates remained constant at about 5 per 1,000 veterans. Mortality at 30 days decreased (7.1% to 5.0%, p < 0.0001), whereas rehospitalization for heart failure at 30 days increased (5.6% to 6.1%, p = 0.11). After adjustment for patient characteristics, the odds ratio for rehospitalization in 2006 (vs. 2002) was 0.54 (95% confidence interval [CI]: 0.47 to 0.61) for mortality, but 1.21 (95% CI: 1.04 to 1.41) for heart failure rehospitalization at 30 days.
Conclusions Recent mortality and rehospitalization rates in the Veterans Affairs Health Care System have trended in opposite directions. These results have implications for using rehospitalization as a measure of quality of care. (J Am Coll Cardiol 2010;56:362-8) (c) 2010 by the American College of Cardiology Foundation

AB Clathrin-dependent endocytosis is a main entry mechanism for the glycolipid-binding Shiga toxin (Stx), although clathrin-independent pathways are also involved. Binding of Stx to its receptor Gb3 not only is essential for Stx retrograde transport to the endoplasmic reticulum and toxicity but also activates signaling through the tyrosine kinase Syk. We previously described that Syk activity is important for Stx entry, but it remained unclear how this kinase modulates endocytosis of Stx. Here we characterized the effects of Stx and Syk on clathrin-coated pit formation. We found that acute treatment with Stx results in an increase in the number of clathrin-coated profiles as determined by electron microscopy and on the number of structures containing the endocytic AP-2 adaptor at the plasma membrane determined by live-cell spinning disk confocal imaging. These responses to Stx require functional Syk activity. We propose that a signaling pathway mediated by Syk and modulated by Stx leads to an increased number of endocytic clathrin-coated structures, thus providing a possible mechanism by which Stx enhances its own endocytosis.

AB Background Olaparib, a novel, orally active poly(ADP-ribose) polymerase (PARP) inhibitor, induced synthetic lethality in BRCA-deficient cells. A maximum tolerated dose and initial signal of efficacy in BRCA-deficient ovarian cancers have been reported. We therefore assessed the efficacy, safety, and tolerability of olaparib alone in women with BRCA1 or BRCA2 mutations and advanced breast cancer.
Methods Women (aged years) with confirmed BRCA1 or BRCA2 mutations and recurrent, advanced breast cancer were assigned to two sequential cohorts in a phase 2 study undertaken in 16 centres in Australia, Germany, Spain, Sweden, the UK, and the USA. The first cohort (n=27) was given continuous oral olaparib at the maximum tolerated dose (400 mg twice daily), and the second (n=27) was given a lower dose (100 mg twice daily). The primary efficacy endpoint was objective response rate (ORR). This study is registered with ClinicalTrials.gov, number NCT00494234.
Findings Patients had been given a median of three previous chemotherapy regimens (range 1-5 in cohort 1, and 2-4 in cohort 2). ORR was 11 (41%) of 27 patients (95% CI 25-59) in the cohort assigned to 400 mg twice daily, and six (22%) of 27 (11-41) in the cohort assigned to 100 mg twice daily. Toxicities were mainly at low grades. The most frequent causally related adverse events in the cohort given 400 mg twice daily were fatigue (grade 1 or 2, 11 [41%]; grade 3 or 4, four [15%]), nausea (grade 1 or 2, 11 [41%]; grade 3 or 4, four [15%]), vomiting (grade 1 or 2, three [11%]; grade 3 or 4, three [11%]), and anaemia (grade 1 or 2, one [4%]; grade 3 or 4, three [11%]). The most frequent causally related adverse events in the cohort given 100 mg twice daily were nausea (grade 1 or 2, 11 [41%]; none grade 3 or 4) and fatigue (grade 1 or 2, seven [26%]; grade 3 or 4, one [4%]).
Interpretation The results of this study provide positive proof of concept for PARP inhibition in BRCA-deficient breast cancers and shows a favourable therapeutic index for a novel targeted treatment strategy in patients with tumours that have genetic loss of function of BRCA1-associated or BRCA2-associated DNA repair. Toxicity in women with BRCA1 and BRCA2 mutations was similar to that reported previously in those without such mutations.

AB Background Olaparib is a novel, orally active poly(ADP-ribose) polymerase (PARP) inhibitor that induces synthetic lethality in homozygous BRCA-deficient cells. We aimed to assess the efficacy and safety of olaparib for treatment of advanced ovarian cancer in patients with BRCA1 or BRCA2 mutations.
Methods In this international, multicentre, phase 2 study, we enrolled two sequential cohorts of women (aged >= 18 years) with confirmed genetic BRCA1 or BRCA2 mutations, and recurrent, measurable disease. The study was undertaken in 12 centres in Australia, Germany, Spain, Sweden, and the USA. The first cohort (n=33) was given continuous oral olaparib at the maximum tolerated dose of 400 mg twice daily, and the second cohort (n=24) was given continuous oral olaparib at 100 mg twice daily. The primary efficacy endpoint was objective response rate (ORR). This study is registered with ClinicalTrials.gov, number NCT00494442.
Findings Patients had been given a median of three (range 1-16) previous chemotherapy regimens. ORR was 11 (33%) of 33 patients (95% CI 20-51) in the cohort assigned to olaparib 400 mg twice daily, and three (13%) of 24 (4-31) in the cohort assigned to 100 mg twice daily. In patients given olaparib 400 mg twice daily, the most frequent causally related adverse events were nausea (grade 1 or 2,14 [42%]; grade 3 or 4, two [6%]), fatigue (grade 1 or 2, ten [30%]; grade 3 or 4, one [3%]), and anaemia (grade 1 or two, five [15%1; grade 3 or 4, one [3%]). The most frequent causally related adverse events in the cohort given 100 mg twice daily were nausea (grade 1 or 2, seven [29%]; grade 3 or 4, two [8%]) and fatigue (grade 1 or 2, nine [38%]; none grade 3 or 4).
Interpretation Findings from this phase 2 study provide positive proof of concept of the efficacy and tolerability of genetically targeted treatment with olaparib in BRCA-mutated advanced ovarian cancer.

TI Rapid modulation of TRH and TRH-like peptide release in rat brain and

AB Leptin is not only a feedback modulator of feeding and energy expenditure but also regulates reproductive functions, CNS development and mood. Obesity and major depression are growing public health concerns which may derive, in part, from disregulation of leptin feedback at the level of the hypothalamic feeding centers and mood regulators within the limbic system. Identifying downstream mediators of leptin action may provide therapeutic opportunities. We and others have previously reported that thyrotropin-releasing hormone (TRH, pGlu-His-Pro-NH(2)) and TRH-like peptides (pGlu-X-Pro-NH(2), where "X" can be any amino acid residue) have neuroprotective, antidepressant, anti-epileptic, analeptic, anti-ataxic, and anorectic properties. For this reason, young, adult male Sprague-Dawley rats were injected ip with 1 mg/kg rat leptin and peptide and protein levels were measured in brain and peripheral tissues at 0, 0.5, 1 and 2 h later. Eleven brain regions: pyriform cortex (PYR), entorhinal cortex (ENT), cerebellum (CBL), nucleus accumbens (NA), frontal cortex (FCX), amygdala (AY), posterior cingulate (PCNG), striatum (STR), hippocampus (HC), medulla oblongata (MED) and anterior cingulate (ACNG) and five peripheral tissues (adrenals, testes, epididymis, pancreas and prostate) were analyzed. TRH and six TRH-like peptide levels in STR fell by 0.5 h consistent with leptin-induced release of these peptides: STR (7 down arrow). Significant changes in TRH and TRH-like peptide levels for other brain regions were: CBL (5 down arrow), ENT (5 down arrow), HC (4 down arrow), AY (4 down arrow), FCX (3 down arrow), and ACNG (1 down arrow). The rapid modulation of TRH and TRH-like peptide release combined with their similarity in behavioral, neuroendocrine, immunomodulatory, metabolic and steroidogenic effects to that of leptin is consistent with these peptides participating in downstream signaling.

TI PTK6 Regulates IGF-1-Induced Anchorage-Independent Survival

LONG-TERM SURVIVAL; FACTOR-I RECEPTOR; GROWTH-FACTOR; IGF-I;

AB Background: Proteins that are required for anchorage-independent survival of tumor cells represent attractive targets for therapeutic intervention since this property is believed to be critical for survival of tumor cells displaced from their natural niches. Anchorage-independent survival is induced by growth factor receptor hyperactivation in many cell types. We aimed to identify molecules that critically regulate IGF-1-induced anchorage-independent survival.
Methods and Results: We conducted a high-throughput siRNA screen and identified PTK6 as a critical component of IGF-1 receptor (IGF-1R)-induced anchorage-independent survival of mammary epithelial cells. PTK6 downregulation induces apoptosis of breast and ovarian cancer cells deprived of matrix attachment, whereas its overexpression enhances survival. Reverse-phase protein arrays and subsequent analyses revealed that PTK6 forms a complex with IGF-1R and the adaptor protein IRS-1, and modulates anchorage-independent survival by regulating IGF-1R expression and phosphorylation. PTK6 is highly expressed not only in the previously reported Her2(+) breast cancer subtype, but also in high grade ER(+), Luminal B tumors and high expression is associated with adverse outcomes.
Conclusions: These findings highlight PTK6 as a critical regulator of anchorage-independent survival of breast and ovarian tumor cells via modulation of IGF-1 receptor signaling, thus supporting PTK6 as a potential therapeutic target for multiple tumor types. The combined genomic and proteomic approaches in this report provide an effective strategy for identifying oncogenes and their mechanism of action.

AB The ehrlichiae are small Gram-negative obligate intracellular bacteria in the family Anaplasmataceae. Ehrlichial infection in an accidental host may result in fatal diseases such as human monocytotropic ehrlichiosis, an emerging, tick-borne disease. Although the role of adaptive immune responses in the protection against ehrlichiosis has been well studied, the mechanism by which the innate immune system is activated is not fully understood. Using Ehrlichia muris as a model organism, we show here that MyD88-dependent signaling pathways play a pivotal role in the host defense against ehrlichial infection. Upon E. muris infection, MyD88-deficient mice had significantly impaired clearance of E. muris, as well as decreased inflammation, characterized by reduced splenomegaly and recruitment of macrophages and neutrophils. Furthermore, MyD88-deficient mice produced markedly lower levels of IL-12, which correlated well with an impaired Th1 immune response. In vitro, dendritic cells, but not macrophages, efficiently produced IL-12 upon E. muris infection through a MyD88-dependent mechanism. Therefore, MyD88-dependent signaling is required for controlling ehrlichial infection by playing an essential role in the immediate activation of the innate immune system and inflammatory cytokine production, as well as in the activation of the adaptive immune system at a later stage by providing for optimal Th1 immune responses.

AB Three-prime untranslated regions (3'UTRs) of metazoan messenger RNAs (mRNAs) contain numerous regulatory elements, yet remain largely uncharacterized. Using polyA capture, 3' rapid amplification of complementary DNA (cDNA) ends, full-length cDNAs, and RNA-seq, we defined similar to 26,000 distinct 3'UTRs in Caenorhabditis elegans for similar to 85% of the 18,328 experimentally supported protein-coding genes and revised similar to 40% of gene models. Alternative 3'UTR isoforms are frequent, often differentially expressed during development. Average 3'UTR length decreases with animal age. Surprisingly, no polyadenylation signal (PAS) was detected for 13% of polyadenylation sites, predominantly among shorter alternative isoforms. Trans-spliced (versus non-trans-spliced) mRNAs possess longer 3'UTRs and frequently contain no PAS or variant PAS. We identified conserved 3'UTR motifs, isoform-specific predicted microRNA target sites, and polyadenylation of most histone genes. Our data reveal a rich complexity of 3'UTRs, both genome-wide and throughout development.

AB We examined the efficacy of reduced-intensity conditioning (RIC) and compared outcomes of 93 patients older than 16 years after RIC with 1428 patients receiving full-intensity conditioning for allografts using sibling and unrelated donors for Philadelphia-negative acute lymphoblastic leukemia (ALL) in first or second complete remission. RIC conditioning included busulfan 9 mg/kg or less (27), melphalan 150 mg/m(2) or less (23), low-dose total body irradiation (TBI; 36), and others (7). The RIC group was older (median 45 vs 28 years, P < .001) and more received peripheral blood grafts (73% vs 43%, P < .001) but had similar other prognostic factors. The RIC versus full-intensity conditioning groups had slightly, but not significantly, less acute grade II-IV graft-versus-host disease (39% vs 46%) and chronic graft-versus-host disease (34% vs 42%), yet similar transplantation-related mortality. RIC led to slightly more relapse (35% vs 26%, P = .08) yet similar age-adjusted survival (38% vs 43%, P = .39). Multivariate analysis showed that conditioning intensity did not affect transplantation-related mortality (P = .92) or relapse risk (P = .14). Multivariate analysis demonstrated significantly improved overall survival with: Karnofsky performance status more than 80, first complete remission, lower white blood count, well-matched unrelated or sibling donors, transplantation since 2001, age younger than 30 years, and conditioning with TBI, but no independent impact of conditioning intensity. RIC merits further investigation in prospective trials of adult ALL. (Blood. 2010; 116(3): 366-374)

TI Anti-diabetic drugs inhibit obesity-linked phosphorylation of PPAR gamma

AB Obesity induced in mice by high-fat feeding activates the protein kinase Cdk5 (cyclin-dependent kinase 5) in adipose tissues. This results in phosphorylation of the nuclear receptor PPAR gamma (peroxisome proliferator-activated receptor c), a dominant regulator of adipogenesis and fat cell gene expression, at serine 273. This modification of PPAR gamma does not alter its adipogenic capacity, but leads to dysregulation of a large number of genes whose expression is altered in obesity, including a reduction in the expression of the insulin-sensitizing adipokine, adiponectin. The phosphorylation of PPAR gamma by Cdk5 is blocked by anti-diabetic PPAR gamma ligands, such as rosiglitazone and MRL24. This inhibition works both in vivo and in vitro, and is completely independent of classical receptor transcriptional agonism. Similarly, inhibition of PPAR gamma phosphorylation in obese patients by rosiglitazone is very tightly associated with the anti-diabetic effects of this drug. All these findings strongly suggest that Cdk5-mediated phosphorylation of PPAR gamma may be involved in the pathogenesis of insulin-resistance, and present an opportunity for development of an improved generation of anti-diabetic drugs through PPAR gamma.

TI Histone H4K20/H3K9 demethylase PHF8 regulates zebrafish brain and

AB X-linked mental retardation (XLMR) is a complex human disease that causes intellectual disability(1). Causal mutations have been found in approximately 90 X-linked genes(2); however, molecular and biological functions of many of these genetically defined XLMR genes remain unknown. PHF8 (PHD (plant homeo domain) finger protein 8) is a JmjC domain-containing protein and its mutations have been found in patients with XLMR and craniofacial deformities. Here we provide multiple lines of evidence establishing PHF8 as the first mono-methyl histone H4 lysine 20 (H4K20me1) demethylase, with additional activities towards histone H3K9me1 and me2. PHF8 is located around the transcription start sites (TSS) of similar to 7,000 RefSeq genes and in gene bodies and intergenic regions (non-TSS). PHF8 depletion resulted in upregulation of H4K20me1 and H3K9me1 at the TSS and H3K9me2 in the non-TSS sites, respectively, demonstrating differential substrate specificities at different target locations. PHF8 positively regulates gene expression, which is dependent on its H3K4me3-binding PHD and catalytic domains. Importantly, patient mutations significantly compromised PHF8 catalytic function. PHF8 regulates cell survival in the zebrafish brain and jaw development, thus providing a potentially relevant biological context for understanding the clinical symptoms associated with PHF8 patients. Lastly, genetic and molecular evidence supports a model whereby PHF8 regulates zebrafish neuronal cell survival and jaw development in part by directly regulating the expression of the homeodomain transcription factor MSX1/MSXB, which functions downstream of multiple signalling and developmental pathways(3). Our findings indicate that an imbalance of histone methylation dynamics has a critical role in XLMR.

AB Accumulating evidence indicates that a sub-population of cancer cells with stem-like properties, termed tumor-initiating cells (T-ICs), exist in many different kinds of malignancies, which have a pivotal role in tumorigenesis, tumor progression, metastasis and post-treatment relapse. However, how the stem-like properties of T-ICs are regulated remains obscure. Our previous study showed that reduction of let-7 microRNA ( miRNA) in breast tumor-initiating cells (BT-ICs) contributes to the maintenance of their self-renewal capacity and undifferentiated status. In this study we show the effect of mir-30 reduction on the stem-like features of BT-ICs. Similar to let-7, mir-30 is reduced in BT-ICs, and the protein level of Ubc9 (ubiquitin-conjugating enzyme 9) and ITGB3 ( integrin b3), the target genes of mir-30, is markedly upregulated. Enforced constitutive expression of mir-30 in BT-ICs inhibits their self-renewal capacity by reducing Ubc9, and induces apoptosis through silencing ITGB3. On the contrary, blocking the miRNA with a specific antisense oligonucleotide (ASO) in differentiated breast cancer cells revived their self-renewal capacity. Furthermore, ectopic expression of mir-30 in BT-IC xenografts reduces tumorigenesis and lung metastasis in nonobese diabetic/severe combined immunodeficient mice, whereas blocking mir-30 expression enhances tumorigenesis and metastasis. Together, our data suggest mir-30 as one of the important miRNAs in regulating the stem-like features of T-ICs. Oncogene ( 2010) 29, 4194-4204; doi: 10.1038/onc.2010.167; published online 24 May 2010

AB Context Recent data regarding the consequences of untreated human immunodeficiency virus (HIV) infection and the expansion of treatment choices for antiretroviral-naive and antiretroviral-experienced patients warrant an update of the International AIDS Society-USA guidelines for the use of antiretroviral therapy in adults with HIV infection.
Objectives To provide updated recommendations for management of HIV-infected adults, using antiretroviral drugs and laboratory monitoring tools available in the international, developed-world setting. This report provides guidelines for when to initiate antiretroviral therapy, selection of appropriate initial regimens, patient monitoring, when to change therapy, and what regimens to use when changing.
Data Sources and Study Selection A panel with expertise in HIV research and clinical care reviewed relevant data published or presented at selected scientific conferences since the last panel report through April 2010. Data were identified through a PubMed search, review of scientific conference abstracts, and requests to antiretroviral drug manufacturers for updated clinical trials and adverse event data.
Data Extraction and Synthesis New evidence was reviewed by the panel. Recommendations were drafted by section writing committees and reviewed and edited by the entire panel. The quality and strength of the evidence were rated and recommendations were made by full panel consensus.
Conclusions Patient readiness for treatment should be confirmed before initiation of antiretroviral treatment. Therapy is recommended for asymptomatic patients with a CD4 cell count <= 500/mu L, for all symptomatic patients, and those with specific conditions and comorbidities. Therapy should be considered for asymptomatic patients with CD4 cell count >500/mu L. Components of the initial and subsequent regimens must be individualized, particularly in the context of concurrent conditions. Patients receiving antiretroviral treatment should be monitored regularly; treatment failure should be detected and managed early, with the goal of therapy, even in heavily pretreated patients, being HIV-1 RNA suppression below commercially available assay quantification limits.

AB Human immunodeficiency virus (HIV)-infected individuals are at high risk of malignancies. However, it is not currently the standard of care to routinely test cancer patients for HIV. In 2006, the Centers for Disease Control and Prevention recommended HIV testing in all health care settings, calling for standard nontargeted "opt-out" HIV screening. For a variety of reasons, routine opt-out HIV testing is still not widely used in the United States. Although many barriers to routine opt-out HIV testing have been addressed, such opt-out HIV testing continues to be conducted primarily in venues that target specific patient populations such as pregnant women. Although opt-out testing has been piloted in emergency departments, less emphasis has been placed on opt-out HIV testing in other clinical settings. In this article, the background, rationale, and evidence for supporting opt-out HIV testing as routine care for cancer patients are presented. In addition, evidence is discussed for the potential of opt-out HIV testing to improve clinical outcomes by facilitating appropriate HIV management during cancer treatment for individuals who are found to be HIV positive.

TI Arthrodesis of the First Metatarsophalangeal Joint: A Robotic Cadaver
Study of the Dorsiflexion Angle
SO JOURNAL OF BONE AND JOINT SURGERY-AMERICAN VOLUME
LA English
DT Article
ID HALLUX-RIGIDUS; PLANTAR PRESSURE; PLATE FIXATION; GAIT ANALYSIS;

AB Background: Arthrodesis of the first metatarsophalangeal joint is indicated for severe osteoarthritis or as a revision of failed treatment for hallux valgus. The literature suggests that an optimum fused dorsiflexion angle is between 20 degrees and 25 degrees from the axis of the first metatarsal. The purpose of this study was to investigate the relationship between dorsiflexion angle and plantar pressure in the postoperative gait. We assumed that there is a fused dorsiflexion angle at which pressures are minimized under the hallux and the first metatarsal head.
Methods: Six cadaver foot specimens underwent incremental changes in simulated fused metatarsophalangeal joint dorsiflexion angle followed by dynamic gait simulation. A robotic gait simulator performed at 50% of body weight and one-fifteenth of physiologic velocity. In vitro tibial kinematics and tendon forces were based on normative in vivo gait and electromyographic data and were manually tuned to match the in vitro ground reaction force and tendon force behavior. Regression lines were calculated for peak pressure and pressure-time integral under the hallux and the metatarsal head by dorsiflexion angle.
Results: Peak pressure and pressure-time integral under the hallux were negatively correlated with dorsiflexion angle (p < 0.004), while peak pressure and pressure-time integral under the metatarsal head were positively correlated with dorsiflexion angle (p < 0.004). The intersection of the regression lines that represented the angle at which peak pressure and pressure-time integral were minimized was 24.7 degrees for peak pressure and 21.3 degrees for pressure-time integral.
Conclusions: Our findings support the hypothesis that an angle-pressure relationship exists following arthrodesis of the first metatarsophalangeal joint and that it is inversely related for the hallux and the metatarsal head. Our results encompass the suggested range of 20 degrees to 25 degrees. Clinical Relevance: This investigation provides a basis for assessing clinical decisions surrounding operative technique and hardware utilization that may improve gait, quality of life, and functional performance in patients undergoing operative treatment of osteoarthritis of the first metatarsophalangeal joint.

AB Monocular lid closure (MC) causes a profound shift in the ocular dominance ( OD) of neurons in primary visual cortex (V1). Anatomical studies in both cat and mouse V1 suggest that large-scale structural rearrangements of eye-specific thalamocortical (TC) axons in response to MC occur much more slowly than the shift in OD. Consequently, there has been considerable debate as to whether the plasticity of TC synapses, which transmit competing visual information from each eye to V1, contributes to the early functional consequences of MC or is simply a feature of long-term deprivation. Here, we used quantitative immuno-electron microscopy to examine the possibility that alterations of TC synapses occur rapidly enough to impact OD after brief MC. The effect of short-term deprivation on TC synaptic structure was examined in male C57BL/6 mice that underwent 3 and 7 d of MC or monocular retinal inactivation (MI) with tetrodotoxin. The data show that 3 d of MC is sufficient to induce substantial remodeling of TC synapses. In contrast, 3 d of MI, which alters TC activity but does not shift OD, does not significantly affect the structure of TC synapses. Our results support the hypothesis that the rapid plasticity of TC synapses is a key step in the sequence of events that shift OD in visual cortex.

AB Social network analysis has long been an untiring topic of sociology. However, until the era of information technology, the availability of data, mainly collected by the traditional method of personal survey, was highly limited and prevented large-scale analysis. Recently, the exploding amount of automatically generated data has completely changed the pattern of research. For instance, the enormous amount of data from so-called high-throughput biological experiments has introduced a systematic or network viewpoint to traditional biology. Then, is "high-throughput'' sociological data generation possible? Google, which has become one of the most influential symbols of the new Internet paradigm within the last ten years, might provide torrents of data sources for such study in this (now and forthcoming) digital era. We investigate social networks between people by extracting information on the Web and introduce new tools of analysis of such networks in the context of statistical physics of complex systems or socio-physics. As a concrete and illustrative example, the members of the 109th United States Senate are analyzed and it is demonstrated that the methods of construction and analysis are applicable to various other weighted networks.

TI R5 Clade C SHIV Strains with Tier 1 or 2 Neutralization Sensitivity:
Tools to Dissect Env Evolution and to Develop AIDS Vaccines in Primate
Models

GLYCOSYLATION; RHESUS-MONKEYS
AB Background: HIV-1 clade C (HIV-C) predominates worldwide, and anti-HIV-C vaccines are urgently needed. Neutralizing antibody (nAb) responses are considered important but have proved difficult to elicit. Although some current immunogens elicit antibodies that neutralize highly neutralization-sensitive (tier 1) HIV strains, most circulating HIVs exhibiting a less sensitive (tier 2) phenotype are not neutralized. Thus, both tier 1 and 2 viruses are needed for vaccine discovery in nonhuman primate models.
Methodology/Principal Findings: We constructed a tier 1 simian-human immunodeficiency virus, SHIV-1157ipEL, by inserting an "early,'' recently transmitted HIV-C env into the SHIV-1157ipd3N4 backbone [ 1] encoding a "late'' form of the same env, which had evolved in a SHIV-infected rhesus monkey (RM) with AIDS. SHIV-1157ipEL was rapidly passaged to yield SHIV-1157ipEL-p, which remained exclusively R5-tropic and had a tier 1 phenotype, in contrast to "late'' SHIV-1157ipd3N4 (tier 2). After 5 weekly low-dose intrarectal exposures, SHIV-1157ipEL-p systemically infected 16 out of 17 RM with high peak viral RNA loads and depleted gut CD4(+) T cells. SHIV-1157ipEL-p and SHIV-1157ipd3N4 env genes diverge mostly in V1/V2. Molecular modeling revealed a possible mechanism for the increased neutralization resistance of SHIV-1157ipd3N4 Env: V2 loops hindering access to the CD4 binding site, shown experimentally with nAb b12. Similar mutations have been linked to decreased neutralization sensitivity in HIV-C strains isolated from humans over time, indicating parallel HIV-C Env evolution in humans and RM.
Conclusions/Significance: SHIV-1157ipEL-p, the first tier 1 R5 clade C SHIV, and SHIV-1157ipd3N4, its tier 2 counterpart, represent biologically relevant tools for anti-HIV-C vaccine development in primates.

TI Plagiarism in Residency Application Essays
SO ANNALS OF INTERNAL MEDICINE
LA English
DT Article
ID SUBSEQUENT DISCIPLINARY ACTION; RESEARCH PUBLICATIONS;
MISREPRESENTATION; STUDENTS
AB Background: Anecdotal reports suggest that some residency application essays contain plagiarized content.
Objective: To determine the prevalence of plagiarism in a large cohort of residency application essays.
Design: Retrospective cohort study.
Setting: 4975 application essays submitted to residency programs at a single large academic medical center between 1 September 2005 and 22 March 2007.
Measurements: Specialized software was used to compare residency application essays with a database of Internet pages, published works, and previously submitted essays and the percentage of the submission matching another source was calculated. A match of more than 10% to an existing work was defined as evidence of plagiarism.
Results: Evidence of plagiarism was found in 5.2% (95% CI, 4.6% to 5.9%) of essays. The essays of non-U.S. citizens were more likely to demonstrate evidence of plagiarism. Other characteristics associated with the prevalence of plagiarism included medical school location outside the United States and Canada; previous residency or fellowship; lack of research experience, volunteer experience, or publications; a low United States Medical Licensing Examination Step 1 score; and nonmembership in the Alpha Omega Alpha Honor Medical Society.
Limitations: The software database is probably incomplete, the 10%-match threshold for defining plagiarism has not been statistically validated, and the study was confined to applicants to 1 institution. Evidence of matching content in an essay cannot be used to infer the applicant's intent and is not sensitive to variations in the cultural context of copying in some societies.
Conclusion: Evidence of plagiarism in residency application essays is more common in international applicants but was found in those by applicants to all specialty programs, from all medical school types, and even among applicants with significant academic honors.

AB Lumbar vertebrae are complicated in structure and function. The purpose of this study was to investigate the in-vivo motion characteristics of different portions of the lumbar vertebrae during functional activities. Motion of L2, L3 and L4 was reproduced using a combined dual fluoroscopic and MR imaging technique during flexion-extension and left-right twisting of the trunk. The ranges of motion (ROM) of the proximal vertebra with respect to the distal one at 3 representative locations: the center of the vertebral body, the center of the spinal canal and the tip of the spinous process were measured. Centers of rotation (COR) of the vertebrae were then determined by calculation of the points of zero motion in 2D sagittal and transverse planes. During flexion-extension, the center of the vertebral body moved less than 0.6 mm, while the tip of the spinous process moved less than 7.5 mm in the sagittal plane. The CORs of both L23 (L2 with respect to L3) and 134 were located inside the vertebral body, at a distance about one-third the length of the vertebral body from the posterior edge. During left-right twisting, the center of the vertebral body moved less than 1.0 mm, while the tip of the spinous process moved less than 1.6 mm in the transverse plane. The CORs of both L23 and L34 were located approximately 30 mm anterior to the front edge of the vertebral body. The results of this study may be used to define the ideal locations for surgical placement of the disc prosthesis, thus help improve the prosthesis design and surgical treatment of various pathological conditions.

AB Purpose
The objective of this study was to evaluate the quality of care provided to uninsured women with breast cancer who received treatment through the Breast and Cervical Cancer Prevention Treatment Program (BCCTP).
Methods
Participants included women with stage I to III breast cancer (n = 658) from a consecutive sample of women 18 years or older who received coverage through the California BCCTP between February 2003 and September 2005 who consented to a survey and medical record review (61% response rate). Quality of breast cancer care was evaluated using 29 evidence-based quality measures developed for the National Initiative for Cancer Care Quality (NICCQ). NICCQ, a largely insured cohort of women diagnosed with stage I to III breast cancer in 1998, was used to benchmark the results.
Results
Twenty-three percent of women presented with stage III disease compared with fewer than 10% nationally. Patients received 93% of recommended care (95% CI, 92% to 93%). Adherence to recommended care within domains ranged from 87% for post-treatment surveillance (95% CI, 84% to 90%) to 97% for diagnostic evaluation (95% CI, 96% to 97%). Compared to the NICCQ cohort, adherence to quality measures was as good or better for the BCCPT cohort in all domains except post-treatment surveillance.
Conclusion
The BCCTP has made important inroads in providing poor, uninsured women with access to high quality care when faced with the diagnosis of breast cancer; however, many present at an advanced stage, which is associated with worse outcomes.

AB Biliary tract cancers (BTC), which encompass intra-and extrahepatic cholangiocarcinomas and gallbladder carcinomas, are a genetically diverse collection of cancers. Evidence suggests distinct models of molecular and pathologic progression, and a growing body of genetics data points to a heterogeneous collection of underlying mutations in key oncogenes and tumor suppressor genes. Although tumor genetics have been used to tailor individual treatment regimens and guide clinical decision making in other cancers, these principles have not been applied in BTC. Recent clinical trials with targeted therapies seem promising, although the relationships between subsets of patients with positive responses to therapy and tumor genetics remain unexplored. Here, we summarize the molecular pathogenesis and genetics of BTCs and animal modeling and relate these to recent and ongoing clinical trials with targeted agents.

AB Background: Tumor cell invasion into adjacent normal brain is a mesenchymal feature of GBM and a major factor contributing to their dismal outcomes. Therefore, better understandings of mechanisms that promote mesenchymal change in GBM are of great clinical importance to address invasion. We previously showed that the bHLH transcription factor TWIST1 which orchestrates carcinoma metastasis through an epithelial mesenchymal transition (EMT) is upregulated in GBM and promotes invasion of the SF767 GBM cell line in vitro.
Results: To further define TWIST1 functions in GBM we tested the impact of TWIST1 over-expression on invasion in vivo and its impact on gene expression. We found that TWIST1 significantly increased SNB19 and T98G cell line invasion in orthotopic xenotransplants and increased expression of genes in functional categories associated with adhesion, extracellular matrix proteins, cell motility and locomotion, cell migration and actin cytoskeleton organization. Consistent with this TWIST1 reduced cell aggregation, promoted actin cytoskeletal re-organization and enhanced migration and adhesion to fibronectin substrates. Individual genes upregulated by TWIST1 known to promote EMT and/or GBM invasion included SNAI2, MMP2, HGF, FAP and FN1. Distinct from carcinoma EMT, TWIST1 did not generate an E-to N-cadherin " switch" in GBM cell lines. The clinical relevance of putative TWIST target genes SNAI2 and fibroblast activation protein alpha (FAP) identified in vitro was confirmed by their highly correlated expression with TWIST1 in 39 human tumors. The potential therapeutic importance of inhibiting TWIST1 was also shown through a decrease in cell invasion in vitro and growth of GBM stem cells.
Conclusions: Together these studies demonstrated that TWIST1 enhances GBM invasion in concert with mesenchymal change not involving the canonical cadherin switch of carcinoma EMT. Given the recent recognition that mesenchymal change in GBMs is associated with increased malignancy, these findings support the potential therapeutic importance of strategies to subvert TWIST1-mediated mesenchymal change.

AB It is well established that CD4(+) CD8(+) thymocytes are more sensitive to myriad death stimuli than CD4(+) or CD8(+) single positive (SP) thymocytes. The mechanism behind this hypersensitivity to apoptosis of CD4(+) CD8(+) thymocytes is not understood. To test whether the difference lay in the apoptotic preset of mitochondria, established by the BCL-2 family of proteins, we developed a method, FACS-based BH3 profiling. Using this tool, we could discriminate thymocyte subpopulations and demonstrate that mitochondria in double positive (DP) thymocytes are more primed for death than those in single positive counterparts. Loss of proapoptotic BIM, known to cause autoimmunity, also causes loss of "priming." Priming is a phenotype with physiologic consequences, which can be measured at the single-cell level in complex samples using FACS-based BH3 profiling.

AB Aire promotes the ectopic expression of a repertoire of peripheral-tissue antigens (PTAs) in thymic medullary epithelial cells (MECs) to mediate deletional tolerance and thereby prevent autoimmunity. Binding of hypomethylated histone 3 (H3)-tails by Aire's plant homeodomain (PHD) finger is essential for Aire function in cultured cell models, prompting speculation that Aire-PHD:H3-tail interactions underlie targeting of Aire to weakly transcribed loci. To evaluate the role of Aire's PHD finger in MECs on a global scale in vivo, we complemented Aire-deficient mice with a mutant of Aire that inhibits its binding to hypomethylated H3K4 residues. Although the range of Aire-targeted genes was largely unaffected in these mice, the D299A mutation caused a global dampening of Aire's transcriptional impact, resulting in an autoimmune disease similar in profile to that of their Aire-deficient counterparts. To test whether a low H3K4 methylation state is sufficient for Aire targeting, we overexpressed an H3K4-specific demethylase in an Aire-dependent cultured cell system, and determined its capacity to extend Aire's transcriptional footprint. The range and magnitude of Aire-regulated genes was largely unaffected, the only genes additionally induced by Aire in this context being those already accessed for repression. In short, Aire's H3-binding module is necessary for Aire-mediated regulation of gene expression and central tolerance induction, but this influence is unlikely to reflect a targeting mechanism solely based on the recognition of hypomethylated H3K4 residues.

AB Defective RNA metabolism is an emerging mechanism involved in ALS pathogenesis and possibly in other neurodegenerative disorders. Here, we show that microRNA (miRNA) activity is essential for long-term survival of postmitotic spinal motor neurons (SMNs) in vivo. Thus, mice that do not process miRNA in SMNs exhibit hallmarks of spinal muscular atrophy (SMA), including sclerosis of the spinal cord ventral horns, aberrant end plate architecture, and myofiber atrophy with signs of denervation. Furthermore, a neurofilament heavy subunit previously implicated in motor neuron degeneration is specifically up-regulated in miRNA-deficient SMNs. We demonstrate that the heavy neurofilament subunit is a target of miR-9, a miRNA that is specifically down-regulated in a genetic model of SMA. These data provide evidence for miRNA function in SMN diseases and emphasize the potential role of miR-9-based regulatory mechanisms in adult neurons and neurodegenerative states.

We developed two decision analytic Monte Carlo computer simulation models: (1) an Initial Prevention Model depicting the decision whether to administer C. difficile vaccine to patients at-risk for CDI and (2) a Recurrence Prevention Model depicting the decision whether to administer C. difficile vaccine to prevent CDI recurrence. Our results suggest that a C. difficile vaccine could be cost-effective over a wide range of C. difficile risk, vaccine costs, and vaccine efficacies especially, when being used post-CDI treatment to prevent recurrent disease.

AB Background Vitamin D is crucial for maintenance of musculoskeletal health, and might also have a role in extraskeletal tissues. Determinants of circulating 25-hydroxyvitamin D concentrations include sun exposure and diet, but high heritability suggests that genetic factors could also play a part. We aimed to identify common genetic variants affecting vitamin D concentrations and risk of insufficiency.
Methods We undertook a genome-wide association study of 25-hydroxyvitamin D concentrations in 33 996 individuals of European descent from 15 cohorts. Five epidemiological cohorts were designated as discovery cohorts (n=16 125), five as in-silico replication cohorts (n=9367), and five as de-novo replication cohorts (n=8504). 25-hydroxyvitamin D concentrations were measured by radioimmunoassay, chemiluminescent assay, ELISA, or mass spectrometry. Vitamin D insufficiency was defined as concentrations lower than 75 nmol/L or 50 nmol/L. We combined results of genome-wide analyses across cohorts using Z-score-weighted meta-analysis. Genotype scores were constructed for confirmed variants.
Findings Variants at three loci reached genome-wide significance in discovery cohorts for association with 25-hydroxyvitamin D concentrations, and were confirmed in replication cohorts: 4p12 (overall p=1.9x10(-109) for rs2282679, in GC); 11q12 (p=2.1x10(-22) for rs12785878, near DHCR7); and 11p15 (p=3.3x10(-20) for rs10741657, near CYP2R1). Variants at an additional locus (20q13, CYP24A1) were genome-wide significant in the pooled sample (p=6.0x10(-10) for rs6013897). Participants with a genotype score (combining the three confirmed variants) in the highest quartile were at increased risk of having 25-hydroxyvitamin D concentrations lower than 75 nmol/L (OR 2.47, 95% CI 2.20-2.78, p=2.3x10(-48)) or lower than 50 nmol/L (1.92, 1.70-2-16, p=1.0x10(-26)) compared with those in the lowest quartile.
Interpretation Variants near genes involved in cholesterol synthesis, hydroxylation, and vitamin D transport affect vitamin D status. Genetic variation at these loci identifies individuals who have substantially raised risk of vitamin D insufficiency.

TI A Presenilin-1 Mutation Identified in Familial Alzheimer Disease with
Cotton Wool Plaques Causes a Nearly Complete Loss of gamma-Secretase
Activity

AB Mutations in presenilin-1 and presenilin-2 (PS1 and PS2) are the most common cause of familial Alzheimer disease. PS1 and PS2 are the presumptive catalytic components of the multisub-unit gamma-secretase complex, which proteolyzes a number of type I transmembrane proteins, including the amyloid precursor protein (APP) and Notch. APP processing by gamma-secretase produces beta-amyloid peptides (A beta 40 and A beta 42) that accumulate in the Alzheimer disease brain. Here we identify a pathogenic L435F mutation in PS1 in two affected siblings with early-onset familial Alzheimer disease characterized by deposition of cerebral cotton wool plaques. The L435F mutation resides in a conserved C-terminal PAL sequence implicated in active site conformation and catalytic activity. The impact of PS1 mutations in and around the PAL motif on gamma-secretase activity was assessed by expression of mutant PS1 in mouse embryo fibroblasts lacking endogenous PS1 and PS2. Surprisingly, the L435F mutation caused a nearly complete loss of gamma-secretase activity, including > 90% reductions in the generation of A beta 40, A beta 42, and the APP and Notch intracellular domains. Two nonpathogenic PS1 mutations, P433L and L435R, caused essentially complete loss of gamma-secretase activity, whereas two previously identified pathogenic PS1 mutations, P436Q and P436S, caused partial loss of function with substantial reductions in production of A beta 40, A beta 42, and the APP and Notch intracellular domains. These results argue against overproduction of A beta 42 as an essential property of presenilin proteins bearing pathogenic mutations. Rather, our findings provide support for the hypothesis that pathogenic mutations cause a general loss of presenilin function.

AB Pyruvate is an important metabolic intermediate, and also is an effective scavenger of hydrogen peroxide and other reactive oxygen species (ROS). Pharmacological administration of pyruvate has been shown to improve organ function in animal models of oxidant-mediated cellular injury. However, pyruvate is relatively unstable in aqueous solutions, which could limit the therapeutic potential of this compound. Ethyl pyruvate (EP), a simple derivative of pyruvic acid, is also an ROS scavenger, but seems to exert pharmacological effects, such as suppression of inflammation, which are at least quantitatively different and in some instances are qualitatively distinct from those exerted by pyruvate anion. Treatment with EP has been shown to improve survival and/or ameliorate organ dysfunction in a wide variety of pre-clinical models of acute illnesses, such as severe sepsis, acute pancreatitis and stroke. Using other animal models, some studies have demonstrated that more prolonged treatment with EP can ameliorate inflammatory bowel disease or slow the rate of growth of malignant tumors. In a clinical trial of patients undergoing cardiac surgery, treatment with EP was shown to be safe, but it failed to improve outcome. The true therapeutic potential of EP and related compounds remains to be elucidated. In this review, some of the biochemical mechanisms, which might be responsible for the pharmacological effects of EP, are discussed. Published by Elsevier Inc.

AB Motivation: The discovery of new and unexpected biomarkers in cardiovascular disease is a highly data-driven process that requires the complementary power of modern metabolite profiling technologies, bioinformatics and biostatistics. Clinical biomarkers of early myocardial injury are lacking. A prospective biomarker cohort study was carried out to identify, categorize and profile kinetic patterns of early metabolic biomarkers of planned myocardial infarction (PMI) and spontaneous (SMI) myocardial infarction. We applied a targeted mass spectrometry (MS)-based metabolite profiling platform to serial blood samples drawn from carefully phenotyped patients undergoing alcohol septal ablation for hypertrophic obstructive cardiomyopathy serving as a human model of PMI. Patients with SMI and patients undergoing catheterization without induction of myocardial infarction served as positive and negative controls to assess generalizability of markers identified in PMI.
Results: To identify metabolites of high predictive value in tandem mass spectrometry data, we introduced a new feature selection method for the categorization of metabolic signatures into three classes of weak, moderate and strong predictors, which can be easily applied to both paired and unpaired samples. Our paradigm outperformed standard null-hypothesis significance testing and other popular methods for feature selection in terms of the area under the receiver operating curve and the product of sensitivity and specificity. Our results emphasize that this new method was able to identify, classify and validate alterations of levels in multiple metabolites participating in pathways associated with myocardial injury as early as 10 min after PMI.

AB Hematopoietic development during embryogenesis involves the interaction of extrinsic signaling pathways coupled to an intrinsic cell fate that is regulated by cell-specific transcription factors. Retinoic acid (RA) has been linked to stem cell self-renewal in adults and also participates in yolk sac blood island formation. Here, we demonstrate that RA decreases gata1 expression and blocks primitive hematopoiesis in zebrafish (Danio rerio) embryos, while increasing expression of the vascular marker, fli1. Treatment with an inhibitor of RA biosynthesis or a retinoic acid receptor antagonist increases gata1(+) erythroid progenitors in the posterior mesoderm of wild-type embryos and anemic cdx4(-/-) mutants, indicating a link between the cdx-hox signaling pathway and RA. Overexpression of scl, a DNA binding protein necessary for hematopoietic development, rescues the block of hematopoiesis induced by RA. We show that these effects of RA and RA pathway inhibitors are conserved during primitive hematopoiesis in murine yolk sac explant cultures and embryonic stem cell assays. Taken together, these data indicate that RA inhibits the commitment of mesodermal cells to hematopoietic fates, functioning downstream of cdx4 and upstream of scl. Our studies establish a new connection between RA and scl during development that may participate in stem cell self-renewal and hematopoietic differentiation. (Blood. 2010; 116(2): 201-209)

AB BACKGROUND: Although invasive intraductal papillary mucinous neoplasm (IPMN) of the pancreas is thought to be more indolent than sporadic pancreatic adenocarcinoma (PAC), the natural history remains poorly defined. The authors compared survival and identify prognostic factors after resection for invasive IPMN versus stage-matched PAC. METHODS: The Surveillance, Epidemiology, and End Results database (1991-2005) was used to identify 729 patients with invasive IPMN and 8082 patients with PAC who underwent surgical resection. RESULTS: Patients with resected invasive IPMN experienced improved overall survival when compared with resected PAC (median survival, 21 vs 14 months; P < .001). Stratification by nodal status demonstrated no difference in survival among lymph node-positive patients; however, median survival of resected, lymph node-negative, invasive IPMN was significantly improved compared with lymph node-negative PAC (34 vs 18 months; P < .001). On multivariate analysis, PAC histology was an adverse predictor of overall survival (hazard ratio [HR], 1.31; 95% confidence interval [CI], 1.15-1.50) compared with invasive IPMN. For patients with invasive IPMN, positive lymph nodes (HR, 1.98; 95% CI, 1.50-2.60), high tumor grade (HR, 1.74; 95% CI, 1.31-2.31), tumor size >2 cm (HR, 1.50; 95% CI, 1.04-2.19), and age >66 years (HR, 1.33; 95% CI, 1.03-1.73) were adverse predictors of survival. CONCLUSIONS: Although lymph node-negative invasive IPMN showed improved survival after resection compared with lymph node-negative PAC, the natural history of lymph node-positive invasive IPMN mimicked that of lymph node-positive PAC. The authors also identified adverse predictors of survival in invasive IPMN to guide discussions regarding use of adjuvant therapies and prognosis after resection of invasive IPMN.

CELLS; DECATENATION; INTEGRATION; ELEMENT; GENE
AB Chromosomal translocations are common in leukemia, but little is known about their mechanism. Metnase (also termed SETMAR) is a fusion of a histone methylase and transposase protein that arose specifically in primates. Transposases were thought to be extinct in primates because they would mediate deleterious DNA movement. In primates, Metnase interacts with DNA Ligase IV (Lig IV) and promotes nonhomologous end-joining (NHEJ) DNA repair. We show here that the primate-specific protein Metnase can also enhance NHEJ in murine cells and can also interact with murine Lig IV, indicating that it integrated into the preexisting NHEJ pathway after its development in primates. Significantly, expressing Metnase in murine cells significantly reduces chromosomal translocations. We propose that the fusion of the histone methylase SET domain and the transposase domain in the anthropoid lineage to form primate Metnase promotes accurate intrachromosomal NHEJ and thereby suppresses interchromosomal translocations. Metnase may have been selected for because it has a function opposing transposases and may thus play a key role in suppressing translocations that underlie oncogenicity. (C) 2010 Elsevier Inc.

AB Inflammatory pathways may mediate preparation of the "metastatic soil" in the lungs. Some of these pathways-activation and/or the recruitment of certain inflammatory cells-might depend on vascular endothelial growth factor receptor 1 (VEGFR1) activity. Thus, blocking the activity of VEGFR1 (or the interaction with its ligands) has emerged as a potential antimetastasis strategy to target not only angiogenesis and cancer cell survival and migration, but also the recruitment of tumor growth-promoting bone marrow-derived cells (BMDC). However, inhibition of VEGFR1 activity by blocking antibodies or by genetic deletion of the tyrosine kinase domain neither prevented nor changed the rate of spontaneous metastasis formation after surgical removal of primary tumors. Thus, development of VEGFR1-targeted agents should be pursued in selected tumors (e.g., by identifying cancers that depend on VEGFR1 signaling for survival) or in specific combination therapies. Preventing metastasis will likely require identification and blockade of additional or alternative proinflammatory pathways that mediate the priming of the metastatic soil and the growth of micrometastases.

TI PIK3CA Mutations in In situ and Invasive Breast Carcinomas
SO CANCER RESEARCH
LA English
DT Article
ID CANCER; GENE; PI3K
AB The PIK3 signaling pathway has been identified as one of the most important and most frequently mutated pathways in breast cancer. Somatic mutations in the catalytic subunit of PIK3CA have been found in a significant fraction of breast carcinomas, and it has been proposed that mutant PIK3CA plays a role in tumor initiation. However, the majority of primary human tumors analyzed for genetic alterations in PIK3CA have been invasive breast carcinomas and the frequency of PIK3CA mutations in preinvasive lesions has not been explored. To investigate this, we sequenced exons 9 and 20 of PIK3CA in pure ductal carcinoma in situ ( DCIS), DCIS adjacent to invasive carcinoma, and invasive ductal breast carcinomas. In a subset of cases, both in situ and invasive areas were analyzed from the same tumor. We found that the frequency of PIK3CA mutations was essentially the same (similar to 30%) in all three histologic groups. In some cases, in situ and invasive areas of the same tumor were discordant for PIK3CA status, and in two cases in which multiple invasive and adjacent in situ areas within the same tumor were analyzed independently, we detected intratumor heterogeneity for PIK3CA mutations. Our results suggest that mutation of PIK3CA is an early event in breast cancer that is more likely to play a role in breast tumor initiation than in invasive progression, although a potential role for exon 9 mutations in the progression of a subset of DCIS cases cannot be excluded.

AB Tumor neovascularization and growth might be promoted by the recruitment of bone marrow-derived cells (BMDC), which include endothelial precursor cells and "vascular modulatory" myelomonocytic (CD11b+) cells. BMDCs may also drive tumor regrowth after certain chemotherapeutic and vascular disruption treatments. In this study, we evaluated the role of BMDC recruitment in breast and lung carcinoma xenograft models after local irradiation (LI). We depleted the bone marrow by including whole-body irradiation (WBI) of 6 Gy as part of a total tumor dose of 21 Gy, and compared the growth delay with the one achieved after LI of 21 Gy. In both models, the inclusion of WBI induced longer tumor growth delays. Moreover, WBI increased lung tumor control probability by LI. Exogenous delivery of BMDCs from radiation-naive donors partially abrogated the WBI effect. Myeloid BMDCs, primarily macrophages, rapidly accumulated in tumors after LI. Intratumoral expression of stromal-derived factor 1 alpha (SDF-1 alpha), a chemokine that promotes tissue retention of BMDCs, was noted 2 days after LI. Conversely, treatment with an inhibitor of SDF-1 alpha receptor CXCR4 (AMD3100) with LI significantly delayed tumor regrowth. However, when administered starting from 5 days post-LI, AMD3100 treatment was ineffective. Lastly, with restorative bone marrow transplantation of Tie2-GFP-labeled BMDC population, we observed an increased number of monocytes but not endothelial precursor cells in tumors that recurred following LI. Our results suggest that an increase in intratumoral SDF-1 alpha triggered by LI recruits myelomonocytes/macrophages which promotes tumor regrowth. Cancer Res; 70(14); 5679-85. (C)2010 AACR.

AB HER2 amplification and PIK3CA mutation were validated as biomarkers for sensitivity to the single-agent phosphoinositide 3-kinase (PI3K) inhibitor, GDC-0941, in breast cancer models. A novel expression profile was developed to identify other breast cancers sensitive to PI3K inhibitors. These expression studies highlighted feedback networks connecting TORC1, PI3K, and mitogen-activated protein kinase (MAPK) pathways, and underscored the potential for combination therapies.

AB Src, a membrane-associated nonreceptor tyrosine kinase, plays a crucial role in the coordination and facilitation of cell-signaling pathways controlling a wide range of cellular functions, including growth, survival, invasion, adhesion, and migration. Deregulation and increased activity of Src has been observed in multiple human malignancies, prompting the development of specific inhibitors of Src. In preclinical studies, Src inhibitors show antitumor effects in multiple solid tumor types. Recently completed early-phase trials using the inhibitors dasatinib and bosutinib have suggested modest activity as monotherapy in breast and prostate cancer, with potentially greater activity in combination regimens. Given the interaction between Src and the estrogen receptor, ongoing trials are exploring combinations with endocrine therapy. The relationship between Src and the vascular endothelial growth factor receptor also justifies investigation of combinations with angiogenesis inhibitors. Future trials will continue to explore the contribution of Src inhibition with both chemotherapy and targeted agents. Clin Cancer Res; 16(14); 3526-32. (C) 2010 AACR.

AB Purpose: In brain tumors, cerebral edema is a significant source of morbidity and mortality. Recent studies have shown that inhibition of vascular endothelial growth factor (VEGF) signaling induces transient vascular normalization and reduces cerebral edema, resulting in a modest survival benefit in glioblastoma patients. During anti-VEGF treatment, circulating levels of angiopoietin (Ang)-2 remained high after an initial minor reduction. It is not known, however, whether Ang-2 can modulate anti-VEGF treatment of glioblastoma. Here, we used an orthotopic glioma model to test the hypothesis that Ang-2 is an additional target for improving the efficacy of current anti-VEGF therapies in glioma patients.
Experimental Design: To recapitulate high levels of Ang-2 in glioblastoma patients during anti-VEGF treatment, Ang-2 was ectopically expressed in U87 glioma cells. Animal survival and tumor growth were assessed to determine the effects of Ang-2 and anti-VEGF receptor 2 (VEGFR2) treatment. We also monitored morphologic and functional vascular changes using multiphoton laser scanning microscopy and immunohistochemistry.
Results: Ectopic expression of Ang-2 had no effect on vascular permeability, tumor growth, or survival, although it resulted in higher vascular density, with dilated vessels and reduced mural cell coverage. On the other hand, when combined with anti-VEGFR2 treatment, Ang-2 destabilized vessels without affecting vessel regression and compromised the survival benefit of VEGFR2 inhibition by increasing vascular permeability. VEGFR2 inhibition normalized tumor vasculature whereas ectopic expression of Ang-2 diminished the beneficial effects of VEGFR2 blockade by inhibiting vessel normalization.
Conclusion: Cancer treatment regimens combining anti-VEGF and anti-Ang-2 agents may be an effective strategy to improve the efficacy of current anti-VEGF therapies. Clin Cancer Res; 16(14); 3618-27. (c) 2010 AACR.

AB Purpose: Inhibitors of TORC1 have been shown to be active in patients with metastatic renal cell carcinoma (RCC). As the phosphatidylinositol 3-kinase (PI3K) pathway activates numerous other kinases, transcription factors, and proteins associated with cell growth and survival besides mammalian target of rapamycin (mTOR), disruption of this pathway upstream of mTOR may be more effective than inhibition of TORC1 alone.
Experimental Design: To investigate this possibility, the dual PI3K/mTOR inhibitor NVP-BEZ235 was compared with rapamycin in RCC cell lines and xenografts generated from 786-O and A498 cells.
Results: Treatment of RCC cell lines with NVP-BEZ235 in vitro resulted in the nuclear translocation of p27, greater reduction in tumor cell proliferation, and more complete suppression of Akt, Mnk-1, eIF4E, and 4EBP-1 phosphorylation and cyclin D1 and hypoxia-inducible factor 2 alpha (HIF2 alpha) expression than that achieved with rapamycin. The reduction of HIF2a levels correlated with reduced HIF activity as determined by luciferase assay. NVP-BEZ235 induced growth arrest in both the 786-O and A498 xenografts that was associated with inhibition of Akt and S6 phosphorylation as well as the induction of apoptosis and reduction in markers of tumor cell proliferation. In contrast, rapamycin induced only minimal growth retardation.
Conclusion: Dual inhibition of PI3K/mTOR with NVP-BEZ235 induced growth arrest in RCC cell lines both in vitro and in vivo more effectively than inhibition of TORC1 alone. These results provide the rationale for the clinical assessment of agents such as NVP-BEZ235 in patients with advanced RCC. Clin Cancer Res; 16(14); 3628-38. (c) 2010 AACR.

AB Background. Human immunodeficiency virus (HIV) elite controllers are able to control infection with HIV-1 spontaneously to undetectable levels in the absence of antiretroviral therapy, but the mechanisms leading to this phenotype are poorly understood. Although low frequencies of HIV-infected peripheral CD4(+) T cells have been reported in this group, it remains unclear to what extent these are due to viral attenuation, active immune containment, or intracellular host factors that restrict virus replication.
Methods. We assessed proviral DNA levels, autologous viral growth from and infectability of in vitro activated, CD8(+) T cell-depleted CD4(+) T cells from HIV elite controllers (mean viral load, <50 copies/mL), viremic controllers (mean viral load, <2000 copies/mL), chronic progressors, and individuals receiving highly active antiretroviral therapy.
Results. Although we successfully detected autologous virus production in ex vivo activated CD4(+) T cells from all chronic progressors and from most of the viremic controllers, we were able to measure robust autologous viral replication in only 2 of 14 elite controllers subjected to the same protocol. In vitro activated autologous CD4(+) T cells from elite controllers, however, supported infection with both X4 and R5 tropic HIV strains at comparable levels to those in CD4(+) T cells from HIV-uninfected subjects. Proviral DNA levels were the lowest in elite controllers, suggesting that extremely low frequencies of infected cells contribute to difficulty in isolation of virus.
Conclusions. These data indicate that elite control is not due to inability of activated CD4(+) T cells to support HIV infection, but the relative contributions of host and viral factors that account for maintenance of low-level infection remain to be determined.

AB Imaging has become a crucial tool in oncology throughout the course of disease detection and management, and is an integral part of clinical trials. Anatomical and functional imaging led the way, providing valuable information used in the diagnosis of disease, including data regarding the size and location of the tumour and on physiological processes such as blood flow and perfusion. As understanding of cancer pathogenesis has advanced through the identification of genetic, biochemical and cellular alterations in evolving tumours, emphasis has been put on developing methods to detect and serially monitor such alterations. This class of approaches is referred to as molecular imaging. Molecular imaging offers the potential for increasingly sensitive and specific visualisation and quantification of biological processes at the cellular and molecular level. These approaches have become established as essential tools for cancer research, early cancer detection and staging, and monitoring and predicting response to targeted therapies. Here, we discuss recent advances in the development of molecular imaging agents and their implementation in basic cancer research as well as in more rationalised approaches to cancer care.

AB Mitochondria serve a critical role in physiology and disease. The genetic basis of mitochondrial regulation in mammalian cells has not yet been detailed. We performed a large-scale RNAi screen to systematically identify genes that affect mitochondrial abundance and function. This screen revealed previously unrecognized roles for >150 proteins in mitochondrial regulation. We report that increased Wnt signals are a potent activator of mitochondrial biogenesis and reactive oxygen species (ROS) generation, leading to DNA damage and acceleration of cellular senescence in primary cells. The signaling protein insulin receptor substrate-1 (IRS-1), shown here to be a transcriptional target of Wnt, is induced in this setting. The increased level of IRS-1 drives activation of mitochondrial biogenesis; furthermore, in insulin-responsive cell types, it enhances insulin signaling, raising the possibility that Wnt proteins may be used to modulate glucose homeostasis. Our results identify a key component of the mitochondrial regulatory apparatus with a potentially important link to metabolic and degenerative disorders.

AB Epithelial-mesenchymal interactions are key to skin morphogenesis and homeostasis. We report that maintenance of the hair follicle keratinocyte cell fate is defective in mice with mesenchymal deletion of the CSL/RBP-J kappa gene, the effector of "canonical'' Notch signaling. Hair follicle reconstitution assays demonstrate that this can be attributed to an intrinsic defect of dermal papilla cells. Similar consequences on hair follicle differentiation result from deletion of Wnt5a, a specific dermal papilla signature gene that we found to be under direct Notch/CSL control in these cells. Functional rescue experiments establish Wnt5a as an essential downstream mediator of Notch-CSL signaling, impinging on expression in the keratinocyte compartment of FoxN1, a gene with a key hair follicle regulatory function. Thus, Notch/CSL signaling plays a unique function in control of hair follicle differentiation by the underlying mesenchyme, with Wnt5a signaling and FoxN1 as mediators.

AB Purpose: Six months of androgen suppression therapy (AST) plus radiation (RT) prolongs survival vs. RT alone in men with unfavorable risk localized prostate cancer (PCa), but it is unknown if this benefit applies to all risk subgroups and, in particular, the intermediate-risk group.
Methods and Materials: Among 206 men with stages T1b to T2b PCa and either a prostate-specific antigen level of >10 or a Gleason score of >= 7 or MRI evidence of T3 disease randomized to receive 70 Gy of RT with or without 6 months of AST, Cox multivariable analysis was used to assess the impact of AST on overall survival in intermediate- and high-risk localized PCa, adjusting for age, Adult Comorbidity Evaluation 27 comorbidity score, interaction between comorbidity and treatment, and known prognostic factors. Survival estimates were compared using a two-sided log-rank test.
Results: After an 8.2-year median follow-up, 74 men died. Compared to treatment with AST plus RT, treatment with RT alone was associated with an increased risk of death in intermediate-risk (adjusted hazard ratio, 3.0 [95% confidence interval, 1.3-7.2]; p = 0.01) and high-risk PCa (adjusted hazard ratio, 3.3 [95% confidence interval, 0.94-11.3]; p = 0.06). The survival benefit of adding AST was restricted to men with no or mild comorbidity in both the intermediate-risk (90.9% vs. 85.8% survival, respectively, at 7 years for AST plus RT vs. RT alone; p = 0.009) and high-risk (88.9% vs. 51.2% survival, respectively, at 7 years for AST plus RT vs. RT alone; p = 0.007) subgroups.
Conclusions: In men with localized PCa who have no or mild comorbidity, adding 6 months of AST to RT was associated with improved survival for those with both intermediate-risk and high-risk disease, but in men with moderate to severe comorbidity, no benefit was observed in either risk group.

AB Purpose: At present, radiation (RT) fields are based largely, and often solely, on bony anatomy. Recent efforts have been taken to better define lymphatic regions for RT planning. Lymphotrophic nanoparticle-enhanced MRI (LN-MRI) allows for accurate identification of malignant and benign lymph nodes. We sought to evaluate RT delivery to lymphatics for breast cancer using LN-MRI.
Methods and Materials: Twenty-three patients with breast cancer underwent LN-MRI. MRIs were anatomically registered to a reference CT; benign and malignant lymph nodes were contoured. Standard RT fields were planned and dose calculated to prescribe 45-50 Gy. Lymphatic regions were contoured on CT. Coverage of LN-MRI lymph nodes by RT fields and contoured lymphatics were assessed.
Results: Eighty-one percent of all lymph nodes defined by LN-MRI were covered by the 45-Gy isodose line; 82% of malignant and 79% of benign. The 50-Gy isodose line only encompassed 60% of LN-MRI defined lymph nodes-64% of malignant and 59% of benign. For nodal volumes contoured in the absence of a margin, 86% of actual lymph nodes were within contoured volumes. When a 5-mm expansion was added, 99% were included.
Conclusions: LN-MRI is a useful tool to delineate the location of breast regional lymphatics. These results suggest less than desired coverage of lymph nodes using standard RT fields and that a margin may be advisable when defining nodal volumes by CT. The use of IMRT and RT in lieu of surgery makes accurate definition of the location of breast regional lymphatics of paramount importance. (C) 2010 Elsevier Inc.

AB Purpose: To review the outcomes and tolerability of full-dose chemoradiation in elderly patients aged 75 years or older with localized pancreatic cancer.
Methods and Materials: We retrospectively reviewed patients aged 75 years or older with nonmetastatic pancreatic cancer treated with chemoradiation therapy at two institutions from 2002 to 2007. Patients were analyzed for treatment toxicity, local recurrences, distant metastases, and survival.
Results: A total of 42 patients with a median age of 78 years (range, 75-90 years) who received chemoradiation therapy for pancreatic cancer were identified. Of the patients, 24 had locally advanced disease treated with definitive chemoradiation, and 18 had disease treated with surgery and chemoradiation. Before chemoradiotherapy, the mean Eastern Cooperative Oncology Group performance status was 1.0 +/- 0.8, and the mean 6-month weight loss was 5.3 +/- 3.8 kg. The mean radiation dose delivered was 48.1 +/- 9.2 Gy. All patients received fluoropyrimidine-based chemotherapy concurrently with radiotherapy. In all, 8 patients (19%) were hospitalized, 7 (17%) had an emergency room visit, 15(36%) required a radiation treatment break, 3(7%) required a chemotherapy break, 9(21%) did not complete therapy, and 22 (49%) had at least one of these adverse events. The most common toxicities were nausea, pain, and failure to thrive. Median overall survival was 8.6 months (95% confidence interval, 7.2-13.1) in patients who received definitive chemoradiation therapy and 20.6 months (95% confidence interval, 9.5-infinity) in patients who underwent resection and chemoradiation therapy.
Conclusions: In this dataset of very elderly patients with pancreatic cancer and good Eastern Cooperative Oncology Group performance status, outcomes after chemoradiotherapy were similar to those among historic controls for patients with locally advanced and resected pancreatic cancer, although many patients experienced substantial treatment-related toxicity.

AB Renal ischemia reperfusion injury (IRI) occurs after reduced renal blood flow and is a major cause of acute injury in both native and transplanted kidneys. Studies have shown diverse cell types in both the innate and the adaptive immune systems participate in kidney IRI as dendritic cells, macrophages, neutrophils, B cells, CD4(+) NK(+) cells, and CD4(+) T cells all contribute to this form of injury. Recently, we have found that NK cells induce apoptosis in tubular epithelial cells (TECs) and also contribute to renal IRI. However, the mechanism of NK cell migration and activation during kidney IRI remains unknown. In this study, we have identified that kidney TECs express a high level of osteopontin (OPN) in vitro and in vivo. C57BL/6 OPN-deficient mice have reduced NK cell infiltration with less tissue damage compared with wild-type C57BL/6 mice after ischemia. OPN can directly activate NK cells to mediate TEC apoptotic death and can also regulate chemotaxis of NK cells to TECs. Taken together, our study's results indicate that OPN expression by TECs is an important factor in initial inflammatory responses that involves NK cells activity in kidney IRI. Inhibiting OPN expression at an early stage of IRI may be protective and preserve kidney function after transplantation. The Journal of Immunology, 2010, 185: 967-973.

AB Bacillus anthracis remains a serious bioterrorism concern, and the currently licensed vaccine remains an incomplete solution for population protection from inhalation anthrax and has been associated with concerns regarding efficacy and safety. Thus, understanding how to generate long-lasting protective immunity with reduced immunizations or provide protection through postexposure immunotherapeutics are long-sought goals. Through evaluation of a large military cohort, we characterized the levels of antibodies against protective antigen and found that over half of anthrax vaccinees had low serum levels of in vitro toxin neutralization capacity. Using solid-phase epitope mapping and confirmatory assays, we identified several neutralization-associated humoral epitopes and demonstrated that select antipeptide responses mediated protection in vitro. Finally, passively transferred antibodies specific for select epitopes provided protection in an in vivo lethal toxin mouse model. Identification of these antigenic regions has important implications for vaccine design and the development of directed immunotherapeutics.

AB The multiprotein transcriptional Mediator complex provides a key link between RNA polymerase II and upstream transcriptional activator proteins. Previous work has established that the multidrug resistance transcription factors Pdr1 and Pdr3 interact with the Mediator component Med15/Gal11 to drive normal levels of expression of the ATP-binding cassette transporter-encoding gene PDR5 in Saccharomyces cerevisiae. PDR5 transcription is induced upon loss of the mitochondrial genome (rho(0) cells) and here we provide evidence that this rho(0) induction is Med15 independent. A search through other known Mediator components determined that Med12/Srb8, a member of the CDK8 Mediator submodule, is required for rho(0) activation of PDR5 transcription. The CDK8 submodule contains the cyclin C homologue (CycC/Srb11), cyclin-dependent kinase Cdk8/Srb10, and the large Med13/Srb9 protein. Loss of these other proteins did not lead to the same block in PDR5 induction. Chromatin immunoprecipitation analyses demonstrated that Med15 is associated with the PDR5 promoter in both rho(+) and rho(0), whereas Med12 recruitment to this target promoter is highly responsive to loss of the mitochondrial genome. Coimmunoprecipitation experiments revealed that association of Pdr3 with Med12 can only be detected in rho(0) cells. These experiments uncover the unique importance of Med12 in activated transcription of PDR5 seen in rho(0) cells.

AB Patients with Parkinson's disease (PD) often have cognitive deficits from the time of diagnosis. Except in patients with dementia, the impact of cognitive symptoms on daily function is not well documented. This study had two objectives: (I) to determine the functional significance of cognitive deficits in nondemented patients with PD and (2) to assess the sensitivity of two measures of global cognitive abilities to identify individuals with impaired ADL function. One hundred eleven subjects with PD and a range of cognitive abilities were included. Of these, 20 were diagnosed with PDD. All subjects were assessed with the Mattis Dementia Rating Scale to two (DRS-2) and the Mini-Mental State Examination (MMSE). ADL function was reported by an informant using the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory (ADCS-ADL). The ability of the DRS-2 and MMSE to capture the impact of cognitive impairment on ADL function was assessed in the entire cohort and in subsets of nondemented individuals. After adjustment for covariates, cognition as measured by the DRS-2 was strongly related to ADL function in the entire cohort (partial correlation coefficient = 0.55, P < 0.001). The association remained strong when only nondemented subjects were included (r = 0.42, P < 0.001). The DRS-2 was significantly more accurate than the MMSE, particularly for detecting milder degrees of ADL impairment (ROC area = 0.87 vs. 0.75, P = 0.0008). Cognition is associated with impairment in ADL function, even in nondemented patients with PD. However, sensitive cognitive assessment measures may be needed to identify these functionally relevant impairments. (C) 2010 Movement Disorder Society

AB The risk of developing levodopa-associated dyskinesia is known to vary inversely with the age of Parkinson's disease onset. This study quantifies dyskinesia risks for different Parkinson's onset ages in a patient population treated at the Parkinson's Disease Research, Education, and Clinical Center at the San Francisco Veterans Affairs Medical Center. Medical records were reviewed to determine age of Parkinson's onset, medication history, and dyskinesia onset. Dyskinesia risks were determined by using Kaplan-Meier analysis. Cox proportional hazard models were used to compare age groups and to perform multivariate modeling. This study included 109 patients with Parkinson's, 105 of whom had onset of symptoms after 1989. At 5 years of levodopa treatment, the dyskinesia risk for patients with onset age 40-49 was 70%, decreasing to 42% for onset ages 50-59, 33% for onset ages 60-69, and 24% for onset ages 70-79. Pairwise comparisons between the 40-49 age group and the other age groups were statistically significant in time-to-event models. After 5 years of levodopa treatment, dyskinesia risks became uniformly high regardless of age of onset. These results suggest it is appropriate to use different baseline dyskinesia risks in clinical decision-making for patients on the basis of their ages of onset. However, the most significant difference occurs between ages 40-49 and ages 50-79, and if more than 5 years of levodopa therapy are anticipated, dyskinesia risk may have less utility when deciding upon Parkinson's therapy. Drug studies for Parkinson's disease should also take age of Parkinson's onset into account when analyzing dyskinesia outcomes. (C) 2010 Movement Disorder Society

AB To date, the majority of neurovascular coupling studies focused on the thalamic afferents' activity in layer IV and the corresponding large spiking activity as responsible for functional hyperemia. This paper highlights the role of the secondary and late cortico-cortical transmission in neurovascular coupling. Simultaneous scalp electroencephalography (EEG) and diffuse optical imaging (DOI) measurements were obtained during multiple conditions of event-related electrical forepaw stimulation in 33 male Sprague-Dawley rats divided into 6 groups depending on the maintaining anesthetic - alpha-chloralose, pentobarbital, ketamine-xylazine, fentanyl-droperidol, isoflurane, or propofol. The somatosensory evoked potentials (SEP) were decomposed into four components and the question of which best predicts the hemodynamic responses was investigated. Results of the linear regression analysis show that the hemodynamic response is best correlated with the secondary and late cortico-cortical transmissions and not with the initial thalamic input activity in layer IV. Baseline cerebral blood flow (CBF) interacts with neural activity and influences the evoked hemodynamic responses. Finally, neurovascular coupling appears to be the same across all anesthetics used.

AB Background: Cyclophosphamide and glucocorticoids have been the cornerstone of remission-induction therapy for severe antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis for 40 years. Uncontrolled studies suggest that rituximab is effective and may be safer than a cyclophosphamide-based regimen.
Methods: We conducted a multicenter, randomized, double-blind, double-dummy, noninferiority trial of rituximab (375 mg per square meter of body-surface area per week for 4 weeks) as compared with cyclophosphamide (2 mg per kilogram of body weight per day) for remission induction. Glucocorticoids were tapered off; the primary end point was remission of disease without the use of prednisone at 6 months.
Results: Nine centers enrolled 197 ANCA-positive patients with either Wegener's granulomatosis or microscopic polyangiitis. Baseline disease activity, organ involvement, and the proportion of patients with relapsing disease were similar in the two treatment groups. Sixty-three patients in the rituximab group (64%) reached the primary end point, as compared with 52 patients in the control group (53%), a result that met the criterion for noninferiority (P<0.001). The rituximab-based regimen was more efficacious than the cyclophosphamide-based regimen for inducing remission of relapsing disease; 34 of 51 patients in the rituximab group (67%) as compared with 21 of 50 patients in the control group (42%) reached the primary end point (P=0.01). Rituximab was also as effective as cyclophosphamide in the treatment of patients with major renal disease or alveolar hemorrhage. There were no significant differences between the treatment groups with respect to rates of adverse events.
Conclusions: Rituximab therapy was not inferior to daily cyclophosphamide treatment for induction of remission in severe ANCA-associated vasculitis and may be superior in relapsing disease.

AB Background. Carboplatin is the most effective drug in retinoblastoma but systemic clearance is variable in young patients. While most regimens use a flat close, individualized targeting may provide a more adjusted systemic exposure. Patients and Methods. We compared carboplatin closes between two groups of children, with retinoblastoma that were treated using a flat dose of 560 mg/m(2) or a targeted AUC of 6.5 using a modified Calvert formula. Results. Ninety-eight patients with retinoblastoma received a total of 576 cycles of carboplatin (median 8 cycles). Fifty patients (51%) received a fixed dose per m(2), 32 (33%) received a dose based on AUC, 1 patient received fixed close per kilogram, and in 15 patients a combination AUC and fixed doses was used. The median cumulative carboplatin dose (mg/m(2)) for patients who received eight cycles using fixed per m(2) closing was 2151.8 (range, 1414.2-2852.0), compared to 1104.1 for nine patients who received eight cycles using Calvert closing (range, 779.0-1992.7) (P<0.001). For cycles given using AUC, the median percentage of the hypothetical fixed per m2 close was 70% (range, 48-134%). Younger patients had larger differences. Patients receiving carboplatin based on fixed per m2 dosing were 3.0 times more likely to have a platelet transfusion (95% confidence interval, 1.3-7.3). Conclusions. Carboplatin administration needs to consider the changes in renal function occurring during the first months of life. The use of a targeted AUC provides the most accurate method; however, mg per kg of body weight dosing is a very reliable alternative method. Pediatr Blood Cancer 2010;55:47-54.

AB Background. Rhino-orbital-cerebral disease is a significant manifestation of zygomycosis in solid organ transplant (SOT) recipients. However, its characteristics and outcome are not well addressed.
Methods. SOT recipients with zygomycosis as per the European Organization for Research and Treatment in Cancer and the Mycoses Study Group criteria in a cohort study at our centers published previously and those identified with a PubMed search from the 1950s to November 2009 were studied. Patients with mycosis involving the sinuses, orbits, or central nervous system (CNS) were included.
Results. Patients comprised a total of 90 SOT recipients with rhino-orbital-cerebral zygomycosis, including 13 in our cohort and 77 in the literature. CNS disease occurred in 57% (51 of 90). Overall mortality was 52.3% (46 of 88), and the mortality in patients with CNS disease was 73.5% (36 of 49). In logistic regression analysis, older age (odds ratio [OR] 1.12, 95% confidence interval [CI] 1.04-1.21, P=0.002) was associated with a higher mortality rate, whereas lipid formulations of amphotericin B compared with amphotericin B deoxycholate (OR 0.09, 95% CI 0.02-0.50, P=0.006) and surgery (OR 0.12, 95% CI 0.01-0.94, P=0.043) were independently associated with an improved survival even when controlled for CNS involvement and the era of diagnosis of disease.
Conclusions. Rhino-orbital-cerebral zygomycosis, particularly CNS disease, is associated with substantial mortality rate in SOT recipients. Older age is a significant risk factor for mortality, whereas lipid formulations of amphotericin B and surgery improved outcomes.

TI Regional Variation in Health Care Intensity and Treatment Practices for
End-stage Renal Disease in Older Adults

LA English
DT Article
ID OF-LIFE CARE; DECISION-MAKING; NATIONAL-SURVEY; UNITED-STATES; DIALYSIS;

AB Context An increasing number of older adults are being treated for end-stage renal disease (ESRD) with long-term dialysis.
Objectives To determine how ESRD treatment practices for older adults vary across regions with differing end-of-life intensity of care.
Design, Setting, and Participants Retrospective observational study using a national ESRD registry to identify a cohort of 41 420 adults (of white or black race), aged 65 years or older, who started long-term dialysis or received a kidney transplant between June 1, 2005, and May 31, 2006. Regional end-of-life intensity of care was defined using an index from the Dartmouth Atlas of Healthcare.
Main Outcome Measures Incidence of treated ESRD (dialysis or transplant), preparedness for ESRD (under the care of a nephrologist, having a fistula [vs graft or catheter] at time of hemodialysis initiation), and end-of-life care practices.
Results Among whites, the incidence of ESRD was progressively higher in regions with greater intensity of care and this trend was most pronounced at older ages. Among blacks, a similar relationship was present only at advanced ages (men aged >= 80 years and women aged >= 85 years). Patients living in regions in the highest compared with lowest quintile of end-of-life intensity of care were less likely to be under the care of a nephrologist before the onset of ESRD (62.3% [95% confidence interval {CI}, 61.3%-63.3%] vs 71.1% [95% CI, 69.9%-72.2%], respectively) and less likely to have a fistula (vs graft or catheter) at the time of hemodialysis initiation (11.2% [95% CI, 10.6%-11.8%] vs 16.9% [95% CI, 15.9%-17.8%]). Among patients who died within 2 years of ESRD onset (n=21 190), those living in regions in the highest compared with lowest quintile of end-of-life intensity of care were less likely to have discontinued dialysis before death (22.2% [95% CI, 21.1%-23.4%] vs 44.3% [95% CI, 42.5%-46.1%], respectively), less likely to have received hospice care (20.7% [95% CI, 19.5%-21.9%] vs 33.5% [95% CI, 31.7%-35.4%]), and more likely to have died in the hospital (67.8% [95% CI, 66.5%-69.1%] vs 50.3% [95% CI, 48.5%-52.1%]). These differences persisted in adjusted analyses.
Conclusion There are pronounced regional differences in treatment practices for ESRD in older adults that are not explained by differences in patient characteristics. JAMA. 2010; 304(2): 180-186 www.jama.com

TI Physicians' Perceptions, Preparedness for Reporting, and Experiences

ID MEDICAL PROFESSIONALISM; SOCIAL-CONTRACT; NATIONAL-SURVEY
AB Context Peer monitoring and reporting are the primary mechanisms for identifying physicians who are impaired or otherwise incompetent to practice, but data suggest that the rate of such reporting is lower than it should be.
Objective To understand physicians' beliefs, preparedness, and actual experiences related to colleagues who are impaired or incompetent to practice medicine.
Design, Setting, and Participants Nationally representative survey of 2938 eligible physicians practicing in the United States in 2009 in anesthesiology, cardiology, family practice, general surgery, internal medicine, pediatrics, and psychiatry. Overall, 1891 physicians (64.4%) responded.
Main Outcome Measures Beliefs about and preparedness for reporting and experiences with colleagues who practice medicine while impaired or who are incompetent in their medical practice.
Results Sixty-four percent (n=1120) of surveyed physicians agreed with the professional commitment to report physicians who are significantly impaired or otherwise incompetent to practice. Nonetheless, only 69% (n=1208) of physicians reported being prepared to effectively deal with impaired colleagues in their medical practice, and 64% (n=1126) reported being so prepared to deal with incompetent colleagues. Seventeen percent (n=309) of physicians had direct personal knowledge of a physician colleague who was incompetent to practice medicine in their hospital, group, or practice. Of those with this knowledge, 67% (n=204) reported this colleague to the relevant authority. Underrepresented minorities and graduates of non-US medical schools were less likely than their counterparts to report, and physicians working in hospitals or medical schools were most likely to report. The most frequently cited reason for taking no action was the belief that someone else was taking care of the problem (19% [n=58]), followed by the belief that nothing would happen as a result of the report (15% [n=46]) and fear of retribution (12% [n=36]).
Conclusion Overall, physicians support the professional commitment to report all instances of impaired or incompetent colleagues in their medical practice to a relevant authority; however, when faced with these situations, many do not report. JAMA. 2010; 304(2): 187-193 www.jama.com

AB Recent rodent studies suggest that gonadal hormones influence extinction of conditioned fear. Here we investigated sex differences in, and the influence of estradiol and progesterone on, fear extinction in healthy humans. Men and women underwent a two-day paradigm in which fear conditioning and extinction learning took place on day 1 and extinction recall was tested on day 2. Visual cues were used as the conditioned stimuli and a mild electric shock was used as the unconditioned stimulus. Skin conductance was recorded throughout the experiment and used to measure conditioned responses (CRs). Blood samples were obtained from all women to measure estradiol and progesterone levels. We found that higher estradiol during extinction learning enhanced subsequent extinction recall but had no effects on fear acquisition or extinction learning itself. Sex differences were only observed during acquisition, with men exhibiting significantly higher CRs. After dividing women into low- and high-estradiol groups, men showed comparable extinction recall to high-estradiol women, and both of these groups showed higher extinction recall than low-estradiol women. Therefore, sex differences in extinction memory emerged only after taking into account women's estradiol levels. Lower estradiol may impair extinction consolidation in women. These findings could have practical applications in the treatment of anxiety disorders through cognitive and behavioral therapies. (C) 2010 IBRO. Published by Elsevier Ltd. All rights reserved.

AB Mutations in human copper-zinc superoxide dismutase (SOD1) cause an inherited form of the fatal neurodegenerative disease amyotrophic lateral sclerosis (ALS). Here, we present structures of the pathogenic SOD1 variants D124V and H80R, both of which demonstrate compromised zinc-binding sites. The disruption of the zinc-binding sites in H80R SOD1 leads to conformational changes in loop elements, permitting non-native SOD1-SOD1 interactions that mediate the assembly of these proteins into higher-order filamentous arrays. Analytical ultracentrifugation sedimentation velocity experiments indicate that these SOD1 variants are more prone to monomerization than the wild-type enzyme. Although D124V and H80R SOD1 proteins appear to have fully functional copper-binding sites, inductively coupled plasma mass spectrometery (ICP-MS) and anomalous scattering X-ray diffraction analyses reveal that zinc (not copper) occupies the copper-binding sites in these variants. The absence of copper in these proteins, together with the results of covalent thiol modification experiments in yeast strains with and without the gene encoding the copper chaperone for SOD1 (CCS), suggests that CCS may not fully act on newly translated forms of these polypeptides. Overall, these findings lend support to the hypothesis that immature mutant SOD1 species contribute to toxicity in SOD1-linked ALS.

AB BACKGROUND: MicroRNAs (miRNAs) are small noncoding RNAs that have important roles in numerous cellular processes. Recent studies have shown aberrant expression of miRNAs in prostate cancer tissues and cell lines. On the basis of miRNA microarray data, we found that miR-145 is significantly downregulated in prostate cancer.
METHODS AND RESULTS: We investigated the expression and functional significance of miR-145 in prostate cancer. The expression of miR-145 was low in all the prostate cell lines tested (PC3, LNCaP and DU145) compared with the normal cell line, PWR-1E, and in cancerous regions of human prostate tissue when compared with the matched adjacent normal. Overexpression of miR-145 in PC3-transfected cells resulted in increased apoptosis and an increase in cells in the G2/M phase, as detected by flow cytometry. Investigation of the mechanisms of inactivation of miR-145 through epigenetic pathways revealed significant DNA methylation of the miR-145 promoter region in prostate cancer cell lines. Microarray analyses of miR-145-overexpressing PC3 cells showed upregulation of the pro-apoptotic gene TNFSF10, which was confirmed by real-time PCR and western analysis.
CONCLUSION: One of the genes significantly upregulated by miR-145 overexpression is the proapoptotic gene TNFSF10. Therefore, modulation of miR-145 may be an important therapeutic approach for the management of prostate cancer.

AB Background-Although many genetic epidemiology and biomarker studies have been conducted to examine associations of genetic variants and circulating proteins with cardiovascular disease and risk factors, there has been little study of gene expression or transcriptomics. Quantitative differences in the abundance of transcripts has been demonstrated in malignancies, but gene expression from a large community-based cohort examining risk of cardiovascular disease has never been reported.
Methods and Results-On the basis of preliminary microarray data and previously suggested genes from the literature, we measured expression of 48 genes by high-throughput quantitative reverse-transcriptase polymerase chain reaction in 1846 participants of the Framingham Offspring cohort from RNA derived from isolated platelets and leukocytes. A multivariable stepwise regression model was used to assess clinical correlates of quantitative RNA expression. For specific inflammatory platelet-derived transcripts, including ICAM1, IFNG, IL1R1, IL6, MPO, COX2, TNF, TLR2, and TLR4, there were significant associations with higher body mass index (BMI). Compared with platelets, fewer leukocyte-derived transcripts were associated with BMI or other cardiovascular risk factors. Select transcripts were found to be highly heritable, including GPIBA and COX1. Almost uniformly, heritable transcripts were not those associated with BMI.
Conclusions-Inflammatory transcripts derived from platelets, particularly those part of the nuclear factor kappa B pathway, are associated with BMI, whereas others are heritable. This is the first study, using a large community-based cohort, to demonstrate clinical correlates of gene expression and is consistent with the hypothesis that specific peripheral-blood transcripts play a role in the pathogenesis of coronary heart disease and its risk factors.

AB Regular physical exercise is recommended for the primary prevention of cardiovascular disease. Although the high prevalence of physical inactivity remains a formidable public health issue, participation in exercise programs and recreational sporting events, such as marathons and triathlons, is on the rise. Although regular exercise training reduces cardiovascular disease risk, recent studies have documented elevations in cardiac troponin (cTn) consistent with cardiac damage after bouts of exercise in apparently healthy individuals. At present, the prevalence, mechanism(s), and clinical significance of exercise-induced cTn release remains incompletely understood. This paper will review the biochemistry, prevalence, potential mechanisms, and management of patients with exercise-induced cTn elevations.

AB Objectives The purpose of this study was to investigate the 2-year outcome of percutaneous coronary intervention (PCI) guided by fractional flow reserve (FFR) in patients with multivessel coronary artery disease (CAD).
Background In patients with multivessel CAD undergoing PCI, coronary angiography is the standard method for guiding stent placement. The FAME (Fractional Flow Reserve Versus Angiography for Multivessel Evaluation) study showed that routine FFR in addition to angiography improves outcomes of PCI at 1 year. It is unknown if these favorable results are maintained at 2 years of follow-up.
Methods At 20 U.S. and European medical centers, 1,005 patients with multivessel CAD were randomly assigned to PCI with drug-eluting stents guided by angiography alone or guided by FFR measurements. Before randomization, lesions requiring PCI were identified based on their angiographic appearance. Patients randomized to angiography-guided PCI underwent stenting of all indicated lesions, whereas those randomized to FFR-guided PCI underwent stenting of indicated lesions only if the FFR was <= 0.80.
Results The number of indicated lesions was 2.7 +/- 0.9 in the angiography-guided group and 2.8 +/- 1.0 in the FFR-guided group (p = 0.34). The number of stents used was 2.7 +/- 1.2 and 1.9 +/- 1.3, respectively (p < 0.001). The 2-year rates of mortality or myocardial infarction were 12.9% in the angiography-guided group and 8.4% in the FFR-guided group (p = 0.02). Rates of PCI or coronary artery bypass surgery were 12.7% and 10.6%, respectively (p = 0.30). Combined rates of death, nonfatal myocardial infarction, and revascularization were 22.4% and 17.9%, respectively (p = 0.08). For lesions deferred on the basis of FFR >0.80, the rate of myocardial infarction was 0.2 % and the rate of revascularization was 3.2 % after 2 years.
Conclusions Routine measurement of FFR in patients with multivessel CAD undergoing PCI with drug-eluting stents significantly reduces mortality and myocardial infarction at 2 years when compared with standard angiography-guided PCI.

AB Background: Changes in gene expression in pancreatic beta-cells from type 2 diabetes (T2D) should provide insights into their abnormal insulin secretion and turnover.
Methodology/Principal Findings: Frozen sections were obtained from cadaver pancreases of 10 control and 10 T2D human subjects. Beta-cell enriched samples were obtained by laser capture microdissection (LCM). RNA was extracted, amplified and subjected to microarray analysis. Further analysis was performed with DNA-Chip Analyzer (dChip) and Gene Set Enrichment Analysis (GSEA) software. There were changes in expression of genes linked to glucotoxicity. Evidence of oxidative stress was provided by upregulation of several metallothionein genes. There were few changes in the major genes associated with cell cycle, apoptosis or endoplasmic reticulum stress. There was differential expression of genes associated with pancreatic regeneration, most notably upregulation of members of the regenerating islet gene (REG) family and metalloproteinase 7 (MMP7). Some of the genes found in GWAS studies to be related to T2D were also found to be differentially expressed. IGF2BP2, TSPAN8, and HNF1B (TCF2) were upregulated while JAZF1 and SLC30A8 were downregulated.
Conclusions/Significance: This study made possible by LCM has identified many novel changes in gene expression that enhance understanding of the pathogenesis of T2D.

AB The urinary bladder and associated tract are lined by the urothelium, a transitional epithelium that acts as a specialized permeability barrier that protects the underlying tissue from urine via expression of a highly specific group of proteins known as the uroplakins (UP). To date, our understanding of the developmental processes responsible for urothelial differentiation has been hampered due to the lack of suitable models. In this study, we describe a novel in vitro cell culture system for derivation of urothelial cells from murine embryonic stem cells (ESCs) following cultivation on collagen matrices in the presence all trans retinoic acid (RA). Upon stimulation with micromolar concentrations of RA, ESCs significantly downregulated the pluripotency factor OCT-4 but markedly upregulated UP1A, UP1B, UP2, UP3A, and UP3B mRNA levels in comparison to naive ESCs and spontaneously differentiating controls. Pan-UP protein expression was associated with both p63- and cytokeratin 20-positive cells in discrete aggregating populations of ESCs following 9 and 14 days of RA stimulation. Analysis of endodermal transcription factors such as GATA4 and GATA6 revealed significant upregulation and nuclear enrichment in RA-treated UP2-GFP+ populations. GATA4-/- and GATA6-/- transgenic ESC lines revealed substantial attenuation of RA-mediated UP expression in comparison to wild type controls. In addition, EMSA analysis revealed that RA treatment induced formation of transcriptional complexes containing GATA4/6 on both UP1B and UP2 promoter fragments containing putative GATA factor binding sites. Collectively, these data suggest that RA mediates ESC specification toward a urothelial lineage via GATA4/6-dependent processes.

AB Cisplatin is a first line chemotherapy for most types of cancer. However, its use is dose-limited due to severe nephrotoxicity. Here we report the rational engineering of a novel nanoplatinate inspired by the mechanisms underlying cisplatin bioactivation. We engineered a novel polymer, glucosamine-functionalized polyisobutylene-maleic acid, where platinum (Pt) can be complexed to the monomeric units using a monocarboxylato and an O --> Pt coordinate bond. We show that at a unique platinum to polymer ratio, this complex self-assembles into a nanoparticle, which releases cisplatin in a pH-dependent manner. The nanoparticles are rapidly internalized into the endolysosomal compartment of cancer cells, and exhibit an IC50 (4.25 + 0.16 mu M) comparable to that of free cisplatin (3.87 +/- 0.37 mu M), and superior to carboplatin (14.75 +/- 0.38 mu M). The nanoparticles exhibited significantly improved antitumor efficacy in terms of tumor growth delay in breast and lung cancers and tumor regression in a K-ras(LSL/+)/Pten(fl/fl) ovarian cancer model. Furthermore, the nanoparticle treatment resulted in reduced systemic and nephrotoxicity, validated by decreased biodistribution of platinum to the kidney as quantified using inductively coupled plasma spectroscopy. Given the universal need for a better platinate, we anticipate this coupling of nanotechnology and structure-activity relationship to rationally reengineer cisplatin could have a major impact globally in the clinical treatment of cancer.

AB The worldwide burden of sickle cell disease is enormous, with over 200,000 infants born with the disease each year in Africa alone. Induction of fetal hemoglobin is a validated strategy to improve symptoms and complications of this disease. The development of targeted therapies has been limited by the absence of discrete druggable targets. We developed a unique bead-based strategy for the identification of inducers of fetal hemoglobin transcripts in primary human erythroid cells. A small-molecule screen of bioactive compounds identified remarkable class-associated activity among histone deacetylase (HDAC) inhibitors. Using a chemical genetic strategy combining focused libraries of biased chemical probes and reverse genetics by RNA interference, we have identified HDAC1 and HDAC2 as molecular targets mediating fetal hemoglobin induction. Our findings suggest the potential of isoform-selective inhibitors of HDAC1 and HDAC2 for the treatment of sickle cell disease.

AB The myocardium responds to hemodynamic stress through cellular growth and organ hypertrophy. The impact of cytoskeletal elements on this process, however, is not fully understood. While alpha-actin in cardiomyocytes governs muscle contraction in combination with the myosin motor, the exact role of beta-actin has not been established. We hypothesized that in adult cardiomyocytes, as in non-myocytes, beta-actin can facilitate cytoskeletal rearrangement within cytoskeletal structures such as Z-discs. Using a feline right ventricular pressure overload (RVPO) model, we measured the level and distribution of beta-actin in normal and pressure overloaded myocardium. Resulting data demonstrated enriched levels of beta-actin and enhanced translocation to the Triton-insoluble cytoskeletal and membrane skeletal complexes. In addition, RVPO in vivo and in vitro hypertrophic stimulation with endothelin (ET) or insulin in isolated adult cardiomyocytes enhanced the content of polymerized fraction (F-actin) of beta-actin. To determine the localization and dynamics of beta-actin, we adenovirally expressed GFP-tagged beta-actin in isolated adult cardiomyocytes. The ectopically expressed beta-actin-GFP localized to the Z-discs, costameres, and cell termini. Fluorescence recovery after photobleaching (FRAP) measurements of beta-actin dynamics revealed that beta-actin at the Z-discs is constantly being exchanged with beta-actin from cytoplasmic pools and that this exchange is faster upon hypertrophic stimulation with ET or insulin. In addition, in electrically stimulated isolated adult cardiomyocytes, while beta-actin overexpression improved cardiomyocyte contractility, immunoneutralization of beta-actin resulted in a reduced contractility suggesting that beta-actin could be important for the contractile function of adult cardiomyocytes. These studies demonstrate the presence and dynamics of beta-actin in the adult cardiomyocyte and reinforce its usefulness in measuring cardiac cytoskeletal rearrangement during hypertrophic stimulation.

AB Background:
Drinking has generally been shown to decline with age in older adults. However, results vary depending on the measure of alcohol consumption used and the study population. The goals of this study were to (i) describe changes in drinking in a current cohort of older adults using a variety of measures of drinking and (ii) examine a number of different possible predictors of change.
Methods:
This is a longitudinal study of a community-based sample surveyed at 2 time points, ages 53 and 64 years. We estimated a series of logistic regressions to predict change and stability in drinking categories of nondrinking, moderate drinking, and heavy drinking. Linear regressions were used to predict change in past-month drinking days, past-month average drinks per drinking day, and past-month total drinks.
Results:
From age 53 to 64, average drinks per drinking day and heavy drinking decreased. Frequency of drinking increased for men and women, and total drinks per month increased for men. The most consistent predictors of drinking changes were gender, health, and education. Other factors predicted drinking change but were not consistent across drinking measures including: adolescent IQ, income, lifetime history of alcohol-related problems, religious service attendance, depression, debt, and changes in employment.
Conclusions:
Heavy drinking decreases with age, but we may see more frequent moderate drinking with current and upcoming cohorts of older adults. Components of quantity and frequency of drinking change differently. Composite measures of total alcohol consumption may not be adequate for describing relevant changes in drinking over time. A number of factors predicted patterns of change in drinking and warrant further exploration.

TI Physical Health and Drinking Among Medical Inpatients With Unhealthy

AB Objective:
Unhealthy alcohol use is common in medical inpatients, and hospitalization has been hypothesized to serve as a "teachable moment" that could motivate patients to decrease drinking, but studies of hospital-based brief interventions have often not found decreases. Evaluating associations between physical health and subsequent drinking among medical inpatients with unhealthy alcohol use could inform refinement of hospital-based brief interventions by identifying an important foundation on which to build them. We tested associations between poor physical health and drinking after hospitalization and whether associations varied by alcohol dependence status and readiness to change.
Methods:
Participants were medical inpatients who screened positive for unhealthy alcohol use and consented to participate in a randomized trial of brief intervention (n = 341). Five measures of physical health were independent variables. Outcomes were abstinence and the number of heavy drinking days (HDDs) reported in the 30 days prior to interviews 3 months after hospitalization. Separate regression models were fit to evaluate each independent variable controlling for age, gender, randomization group, and baseline alcohol use. Interactions between each independent variable and alcohol dependence and readiness to change were tested. Stratified models were fit when significant interactions were identified.
Results:
Among all participants, measures of physical health were not significantly associated with either abstinence or number of HDDs at 3 months. Having an alcohol-attributable principal admitting diagnosis was significantly associated with fewer HDDs in patients who were nondependent [adjusted incidence rate ratio (aIRR) 0.10, 95% CI 0.03-0.32] or who had low alcohol problem perception (aIRR 0.36, 95% CI 0.13-0.99) at hospital admission. No significant association between alcohol-attributable principal admitting diagnosis and number of HDDs was identified for participants with alcohol dependence or high problem perception.
Conclusions:
Among medical inpatients with nondependent unhealthy alcohol use and those who do not view their drinking as problematic, alcohol-attributable illness may catalyze decreased drinking. Brief interventions that highlight alcohol-related illness might be more successful.

AB Purpose With three available chemotherapy drugs for advanced colorectal cancer (CRC), response rate (RR) and survival outcomes have improved with associated morbidity, accentuating the need for tools to select optimal individualized treatment. Pharmacogenetics identifies the likelihood of adverse events or response based on variants in genes involved in drug transport, metabolism, and cellular targets.
Patients and Methods Germline DNA was extracted from 520 patients on the North American Gastrointestinal Intergroup N9741 study. Three study arms were evaluated: IFL (fluorouracil [FU] + irinotecan [IRN]), FOLFOX (FU + oxaliplatin), and IROX (IRN + oxaliplatin). Information on adverse events, response, and disease-free survival was available. Thirty-four variants in 15 candidate genes for analysis based on previous associations with adverse events or outcome were assessed. Genotyping was performed using pyrosequencing.
Results All variants were polymorphic. The homozygous UGT1A1*28 allele observed in 9% of patients was associated with risk of grade 4 neutropenia in patients on IROX (55% v 15%; P = .002). Deletion in GSTM1 was associated with grade 4 neutropenia after FOLFOX (28% v 16%; P = .02). Patients with a homozygous variant genotype for GSTP1 were more likely to discontinue FOLFOX because of neurotoxicity (24% v 10%; P = .01). The presence of a CYP3A5 variant was significantly associated with RR on IFL (29% v 60%; P = .0074). Most previously published genotype-toxicity or -efficacy relationships were not validated in this study.
Conclusion This study provides a platform to evaluate pharmacogenetic predictors of response or severe adverse events in advanced CRC. Pharmacogenetic studies can be conducted in multicenter trials, and our findings demonstrate that with continued research, clinical application is practical.

CLAIMS; COLORECTAL-CANCER; UNITED-STATES; PRIMARY-CARE; FOLLOW-UP; TIME;

AB Purpose Understanding delays in cancer diagnosis requires detailed information about timely recognition and follow-up of signs and symptoms. This information has been difficult to ascertain from paper-based records. We used an integrated electronic health record (EHR) to identify characteristics and predictors of missed opportunities for earlier diagnosis of lung cancer.
Methods Using a retrospective cohort design, we evaluated 587 patients of primary lung cancer at two tertiary care facilities. Two physicians independently reviewed each case, and disagreements were resolved by consensus. Type I missed opportunities were defined as failure to recognize predefined clinical clues (ie, no documented follow-up) within 7 days. Type II missed opportunities were defined as failure to complete a requested follow-up action within 30 days.
Results Reviewers identified missed opportunities in 222 (37.8%) of 587 patients. Median time to diagnosis in cases with and without missed opportunities was 132 days and 19 days, respectively (P < .001). Abnormal chest x-ray was the clue most frequently associated with type I missed opportunities (62%). Follow-up on abnormal chest x-ray (odds ratio [OR], 2.07; 95% CI, 1.04 to 4.13) and completion of first needle biopsy (OR, 3.02; 95% CI, 1.76 to 5.18) were associated with type II missed opportunities. Patient adherence contributed to 44% of patients with missed opportunities.
Conclusion Preventable delays in lung cancer diagnosis arose mostly from failure to recognize documented abnormal imaging results and failure to complete key diagnostic procedures in a timely manner. Potential solutions include EHR-based strategies to improve recognition of abnormal imaging and track patients with suspected cancers.

AB Background: In the setting of chronic liver injury in humans, epidermal growth factor (EGF) and EGF receptor (EGFR) are up-regulated and have been proposed to have vital roles in both liver regeneration and development of hepatocellular carcinoma (HCC). Chronic liver injury also leads to hepatic stellate cell (HSC) differentiation and a novel subpopulation of HSCs which express CD133 and exhibit properties of progenitor cells has been described in rats. The carbon tetrachloride (CCl(4))-induced mouse model has been historically relied upon to study liver injury and regeneration. We exposed mice to CCl(4) to assess whether EGF and CD133+ HSCs are up-regulated in chronically injured liver.
Methods: CCl(4) in olive oil was administered to strain A/J mice three times per week by oral gavage.
Results: Multiple well-differentiated HCCs were found in all livers after 15 weeks of CCl(4) treatment. Notably, HCCs developed within the setting of fibrosis and not cirrhosis. CD133 was dramatically up-regulated after CCl(4) treatment, and increased expression of desmin and glial fibrillary acidic protein, representative markers of HSCs, was also observed. EGF expression significantly decreased, contrary to observations in humans, whereas the expression of amphiregulin, another EGFR ligand, was significantly increased.
Conclusions: Species-specific differences exist with respect to the histopathological and molecular pathogenesis of chronic liver disease. CCl(4)-induced chronic liver injury in A/J mice has important differences compared to human cirrhosis leading to HCC.

AB Recent genome-wide studies have demonstrated that pausing of RNA polymerase II (Pol II) occurred on many vertebrate genes. By genetic studies in the zebrafish tif1 gamma mutant moonshine we found that loss of function of Pol II-associated factors PAF or DSIF rescued erythroid gene transcription in tif1 gamma-deficient animals. Biochemical analysis established physical interactions among TIF1 gamma, the blood-specific SCL transcription complex, and the positive elongation factors p-TEFb and FACT. Chromatin immunoprecipitation assays in human CD34(+) cells supported a TIF1 gamma-dependent recruitment of positive elongation factors to erythroid genes to promote transcription elongation by counteracting Pol II pausing. Our study establishes a mechanism for regulating tissue cell fate and differentiation through transcription elongation.

AB The Fanconi anemia (FA) pathway is responsible for interstrand crosslink repair. At the heart of this pathway is the FANCI-FAND2 (ID) complex, which, upon ubiquitination by the FA core complex, travels to sites of damage to coordinate repair that includes nucleolytic modification of the DNA surrounding the lesion and translesion synthesis. How the ID complex regulates these events is unknown. Here we describe a shRNA screen that led to the identification of two nucleases necessary for crosslink repair, FAN1 (KIAA1018) and EXDL2. FAN1 colocalizes at sites of DNA damage with the ID complex in a manner dependent on FAN1's ubiquitin-binding domain (UBZ), the ID complex, and monoubiquitination of FANCD2. FAN1 possesses intrinsic 5'-3' exonuclease activity and endonuclease activity that cleaves nicked and branched structures. We propose that FAN1 is a repair nuclease that is recruited to sites of crosslink damage in part through binding the ubiquitinated ID complex through its UBZ domain.

AB Background: Circulating progenitor cells (CPC) contribute to the homeostasis of the vessel wall, and a reduced CPC count predicts cardiovascular morbidity and mortality. We tested the hypothesis that CPC count improves cardiovascular risk stratification and that this is modulated by low-grade inflammation.
Methodology/Principal Findings: We pooled data from 4 longitudinal studies, including a total of 1,057 patients having CPC determined and major adverse cardiovascular events (MACE) collected. We recorded cardiovascular risk factors and high-sensitive C-reactive protein (hsCRP) level. Risk estimates were derived from Cox proportional hazard analyses. CPC count and/or hsCRP level were added to a reference model including age, sex, cardiovascular risk factors, prevalent CVD, chronic renal failure (CRF) and medications. The sample was composed of high-risk individuals, as 76.3% had prevalent CVD and 31.6% had CRF. There were 331 (31.3%) incident MACE during an average 1.7 +/- 1.1 year follow-up time. CPC count was independently associated with incident MACE even after correction for hsCRP. According to C-statistics, models including CPC yielded a non-significant improvement in accuracy of MACE prediction. However, the integrated discrimination improvement index (IDI) showed better performance of models including CPC compared to the reference model and models including hsCRP in identifying MACE. CPC count also yielded significant net reclassification improvements (NRI) for CV death, non-fatal AMI and other CV events. The effect of CPC was independent of hsCRP, but there was a significant more-than-additive interaction between low CPC count and raised hsCRP level in predicting incident MACE.
Conclusions/Significance: In high risk individuals, a reduced CPC count helps identifying more patients at higher risk of MACE over the short term, especially in combination with a raised hsCRP level.

AB Arteriovenous-lymphatic endothelial cell fates are specified by the master regulators, namely, Notch, COUP-TFII, and Prox1. Whereas Notch is expressed in the arteries and COUP-TFII in the veins, the lymphatics express all 3 cell fate regulators. Previous studies show that lymphatic endothelial cell (LEC) fate is highly plastic and reversible, raising a new concept that all 3 endothelial cell fates may coreside in LECs and a subtle alteration can result in a reprogramming of LEC fate. We provide a molecular basis verifying this concept by identifying a cross-control mechanism among these cell fate regulators. We found that Notch signal down-regulates Prox1 and COUP-TFII through Hey1 and Hey2 and that activated Notch receptor suppresses the lymphatic phenotypes and induces the arterial cell fate. On the contrary, Prox1 and COUP-TFII attenuate vascular endothelial growth factor signaling, known to induce Notch, by repressing vascular endothelial growth factor receptor-2 and neuropilin-1. We show that previously reported podoplanin-based LEC heterogeneity is associated with differential expression of Notch1 in human cutaneous lymphatics. We propose that the expression of the 3 cell fate regulators is controlled by an exquisite feedback mechanism working in LECs and that LEC fate is a consequence of the Prox1-directed lymphatic equilibrium among the cell fate regulators.

TI Functionally defective germline variants of sialic acid acetylesterase
in autoimmunity
SO NATURE
LA English
DT Article
ID MUTATIONS; DISEASE; MARKER
AB Sialic acid acetylesterase (SIAE) is an enzyme that negatively regulates B lymphocyte antigen receptor signalling and is required for the maintenance of immunological tolerance in mice(1,2). Heterozygous loss-of-function germline rare variants and a homozygous defective polymorphic variant of SIAE were identified in 24/923 subjects of European origin with relatively common autoimmune disorders and in 2/648 controls of European origin. All heterozygous loss-of-function SIAE mutations tested were capable of functioning in a dominant negative manner. Ahomozygous secretion-defective polymorphic variant of SIAE was catalytically active, lacked the ability to function in a dominant negative manner, and was seen in eight autoimmune subjects but in no control subjects. The odds ratio for inheriting defective SIAE alleles was 8.6 in all autoimmune subjects, 8.3 in subjects with rheumatoid arthritis, and 7.9 in subjects with type I diabetes. Functionally defective SIAE rare and polymorphic variants represent a strong genetic link to susceptibility in relatively common human autoimmune disorders.

AB BACKGROUND
Testosterone supplementation has been shown to increase muscle mass and strength in healthy older men. The safety and efficacy of testosterone treatment in older men who have limitations in mobility have not been studied.
METHODS
Community-dwelling men, 65 years of age or older, with limitations in mobility and a total serum testosterone level of 100 to 350 ng per deciliter (3.5 to 12.1 nmol per liter) or a free serum testosterone level of less than 50 pg per milliliter (173 pmol per liter) were randomly assigned to receive placebo gel or testosterone gel, to be applied daily for 6 months. Adverse events were categorized with the use of the Medical Dictionary for Regulatory Activities classification. The data and safety monitoring board recommended that the trial be discontinued early because there was a significantly higher rate of adverse cardiovascular events in the testosterone group than in the placebo group.
RESULTS
A total of 209 men (mean age, 74 years) were enrolled at the time the trial was terminated. At baseline, there was a high prevalence of hypertension, diabetes, hyperlipidemia, and obesity among the participants. During the course of the study, the testosterone group had higher rates of cardiac, respiratory, and dermatologic events than did the placebo group. A total of 23 subjects in the testosterone group, as compared with 5 in the placebo group, had cardiovascular-related adverse events. The relative risk of a cardiovascular-related adverse event remained constant throughout the 6-month treatment period. As compared with the placebo group, the testosterone group had significantly greater improvements in leg-press and chest-press strength and in stair climbing while carrying a load.
CONCLUSIONS
In this population of older men with limitations in mobility and a high prevalence of chronic disease, the application of a testosterone gel was associated with an increased risk of cardiovascular adverse events. The small size of the trial and the unique population prevent broader inferences from being made about the safety of testosterone therapy. (ClinicalTrials.gov number, NCT00240981.)

AB Feeding on high-calorie (HC) diets induces serious metabolic imbalances, including obesity. Understanding the mechanisms against excessive body weight gain is critical for developing effective anti-obesity strategies. Here we show that lack of nicotinamide adenine dinucleotide (NAD(+))-dependent deacetylase SIRT1 in pro-opiomelanocortin (POMC) neurons causes hypersensitivity to diet-induced obesity due to reduced energy expenditure. The ability of leptin to properly engage the phosphoinositide 3-kinase (PI3K) signaling in POMC neurons and elicit remodeling of perigonadal white adipose tissue (WAT) is severely compromised in mutant mice. Also, electrophysiological and histomorphomolecular analyses indicate a selective reduction in sympathetic nerve activity and brown-fat-like characteristics in perigonadal WAT of mutant mice, suggesting a physiologically important role for POMC neurons in controlling this visceral fat depot. In summary, our results provide direct genetic evidence that SIRT1 in POMC neurons is required for normal autonomic adaptations against diet-induced obesity.

AB Phosphatidyl inositol 3-kinase (PI3K) signaling in the hypothalamus has been implicated in the regulation of energy homeostasis, but the critical brain sites where this intracellular signal integrates various metabolic cues to regulate food intake and energy expenditure are unknown. Here, we show that mice with reduced PI3K activity in the ventromedial hypothalamic nucleus (VMH) are more sensitive to high-fat diet-induced obesity due to reduced energy expenditure. In addition, inhibition of PI3K in the VMH impaired the ability to alter energy expenditure in response to acute high-fat diet feeding and food deprivation. Furthermore, the acute anorexigenic effects induced by exogenous leptin were blunted in the mutant mice. Collectively, our results indicate that PI3K activity in VMH neurons plays a physiologically relevant role in the regulation of energy expenditure.

AB Background Tamoxifen use has been associated with increased risk of thromboembolic events (TEs) in women with breast cancer and women at high risk for the disease. Factor V Leiden (FVL) is the most common inherited clotting factor mutation and also confers increased thrombosis risk. We investigated whether FVL was associated with TE risk in women with early-stage breast cancer who took adjuvant tamoxifen.
Methods A case-control study was conducted among 34 Cancer and Leukemia Group B (CALGB) institutions. We matched each of 124 women who had experienced a documented TE while taking adjuvant tamoxifen for breast cancer (but who were not necessarily on a CALGB treatment trial) to two control subjects (women who took adjuvant tamoxifen but did not experience TE) by age at diagnosis (+/- 5 years). DNA from blood was analyzed for FVL mutations. Conditional logistic regression was used to estimate odds ratios (ORs) and to evaluate other potential factors associated with TE and tamoxifen use. All P values are based on two-sided tests.
Results FVL mutations were identified in 23 (18.5%) case and 12 (4.8%) control subjects (OR = 4.66, 95% confidence interval = 2.14 to 10.14, P < .001). In the multivariable model, FVL mutation was associated with TE (OR = 4.73, 95% confidence interval = 2.10 to 10.68, P < .001). Other statistically significant factors associated with TE risk were personal history of TE and smoking.
Conclusions Among women taking adjuvant tamoxifen for early-stage breast cancer, those who had a TE were nearly five times more likely to carry a FVL mutation than those who did not have a TE. Postmenopausal women should be evaluated for the FVL mutation before prescription of adjuvant tamoxifen if a positive test would alter therapeutic decision making.

TI Divergent Cortical Generators of MEG and EEG during Human Sleep Spindles

AB Background: Sleep spindles are similar to 1-second bursts of 10-15 Hz activity, occurring during normal stage 2 sleep. In animals, sleep spindles can be synchronous across multiple cortical and thalamic locations, suggesting a distributed stable phase-locked generating system. The high synchrony of spindles across scalp EEG sites suggests that this may also be true in humans. However, prior MEG studies suggest multiple and varying generators.
Methodology/Principal Findings: We recorded 306 channels of MEG simultaneously with 60 channels of EEG during naturally occurring spindles of stage 2 sleep in 7 healthy subjects. High-resolution structural MRI was obtained in each subject, to define the shells for a boundary element forward solution and to reconstruct the cortex providing the solution space for a noise-normalized minimum norm source estimation procedure. Integrated across the entire duration of all spindles, sources estimated from EEG and MEG are similar, diffuse and widespread, including all lobes from both hemispheres. However, the locations, phase and amplitude of sources simultaneously estimated from MEG versus EEG are highly distinct during the same spindles. Specifically, the sources estimated from EEG are highly synchronous across the cortex, whereas those from MEG rapidly shift in phase, hemisphere, and the location within the hemisphere.
Conclusions/Significance: The heterogeneity of MEG sources implies that multiple generators are active during human sleep spindles. If the source modeling is correct, then EEG spindles are generated by a different, diffusely synchronous system. Animal studies have identified two thalamo-cortical systems, core and matrix, that produce focal or diffuse activation and thus could underlie MEG and EEG spindles, respectively. Alternatively, EEG spindles could reflect overlap at the sensors of the same sources as are seen from the MEG. Although our results generally match human intracranial recordings, additional improvements are possible and simultaneous intra-and extra-cranial measures are needed to test their accuracy.

TI Association of CCR2-CCR5 Haplotypes and CCL3L1 Copy Number with Kawasaki

AUTOIMMUNE-DISEASES; HUMAN GENOME; SUSCEPTIBILITY
AB Background: The etiology of Kawasaki Disease (KD) is enigmatic, although an infectious cause is suspected. Polymorphisms in CC chemokine receptor 5 (CCR5) and/or its potent ligand CCL3L1 influence KD susceptibility in US, European and Korean populations. However, the influence of these variations on KD susceptibility, coronary artery lesions (CAL) and response to intravenous immunoglobulin (IVIG) in Japanese children, who have the highest incidence of KD, is unknown.
Methodology/Principal Findings: We used unconditional logistic regression analyses to determine the associations of the copy number of the CCL3L1 gene-containing duplication and CCR2-CCR5 haplotypes in 133 Japanese KD cases [33 with CAL and 25 with resistance to IVIG] and 312 Japanese controls without a history of KD. We observed that the deviation from the population average of four CCL3L1 copies (i.e., or. four copies) was associated with an increased risk of KD and IVIG resistance (adjusted odds ratio (OR) = 2.25, p = 0.004 and OR = 6.26, p = 0.089, respectively). Heterozygosity for the CCR5 HHF*2 haplotype was associated with a reduced risk of both IVIG resistance (OR = 0.21, p = 0.026) and CAL development (OR = 0.44, p = 0.071).
Conclusions/Significance: The CCL3L1-CCR5 axis may play an important role in KD pathogenesis. In addition to clinical and laboratory parameters, genetic markers may also predict risk of CAL and resistance to IVIG.

AB Background: Pharmacologic treatments for erectile dysfunction (ED) have gained popularity among middle-aged and older men. Increased sexual activity among those who use these drugs raises concerns about sexually transmitted diseases (STDs).
Objective: To examine the rates of STDs in men who use and do not use ED drugs.
Design: Retrospective cohort study.
Setting: Database of claims from 1997 to 2006 for 1 410 806 men older than age 40 years with private, employer-based insurance from 44 large companies.
Patients: 33 968 men with at least 1 filled prescription for an ED drug and 1 376 838 patients with no prescription.
Measurements: STD prevalence among users and nonusers of ED drugs.
Results: Users of ED drugs had higher rates of STDs than nonusers the year before initiating ED drug therapy (214 vs. 106 annually per 100 000 persons; P = 0.003) and the year after (105 vs. 65; P = 0.004). After adjustment for age and other comorbid conditions, users of ED drugs had an odds ratio (OR) for an STD of 2.80 (95% CI, 2.10 to 3.75) in the year before initiating drug therapy; the OR was 2.65 (CI, 1.84 to 3.81) in the year after. These differences were largely due to infections with HIV. The OR for HIV infection was 3.32 (CI, 2.38 to 4.36) in the year before and 3.19 (CI, 2.11 to 4.83) in the year after an ED drug prescription was filled. Significant changes in STD rates from the year before to the year after the first ED drug prescription was filled were not documented (adjusted OR for STD for users before vs. after the first ED drug prescription was filled, 0.96 [CI, 0.87 to 1.06]).
Limitation: Selection bias precludes conclusions about whether use of ED treatments directly leads to increases in STDs.
Conclusion: Men who use ED drugs have higher rates of STDs, particularly HIV infection, both in the year before and after use of these drugs. The observed association between ED drug use and STDs may have more to do with the types of patients using ED drugs rather than a direct effect of ED drug availability on STD rates. Counseling about safe sexual practices and screening for STDs should accompany the prescription of ED drugs.

AB Background-Disruption of the balance between matrix metalloproteinases (MMP) and MMP inhibitors (TIMPs) within a myocardial infarct (MI) contributes to left ventricular wall thinning and changes in regional stiffness at the MI region. This study tested the hypothesis that a targeted regional approach through localized high-frequency stimulation (LHFS) using low-amplitude electric pulses instituted within a formed MI scar would alter MMP/TIMP levels and prevent MI thinning.
Methods and Results-At 3 weeks after MI, pigs were randomized for LHFS (n=7; 240 bpm, 0.8 V, 0.05-ms pulses) or were left unstimulated (UNSTIM; n=10). At 4 weeks after MI, left ventricular wall thickness (echocardiography; 0.89 +/- 0.07 versus 0.67 +/- 0.08 cm; P<0.05) and regional stiffness (piezoelectric crystals; 14.70 +/- 2.08 versus 9.11 +/- 1.24; P<0.05) were higher with LHFS than in UNSTIM. In vivo interstitial MMP activity (fluorescent substrate cleavage; 943 +/- 59 versus 1210 +/- 72 U; P<0.05) in the MI region was lower with LHFS than in UNSTIM. In the MI region, MMP-2 levels were lower and TIMP-1 and collagen levels were higher with LHFS than in UNSTIM (all P<0.05). Transforming growth factor-beta receptor 1 and phosphorylated SMAD-2/3 levels within the MI region were higher with LHFS than in UNSTIM. Electric stimulation (4 Hz) of isolated fibroblasts resulted in reduced MMP-2 and MT1-MMP levels but increased TIMP-1 levels compared with unstimulated fibroblasts.
Conclusions-These unique findings demonstrate that LHFS of the MI region altered left ventricular wall thickness and material properties, likely as a result of reduced regional MMP activity. Thus, LHFS may provide a novel means to favorably modify left ventricular remodeling after MI. (Circulation. 2010;122:20-32.)

AB Bacterial cell-wall-associated fibronectin binding proteins A and B (FnBPA and FnBPA) form bonds with host fibronectin. This binding reaction is often the initial step in prosthetic device infections. Atomic force microscopy was used to evaluate binding interactions between a fibronectin-coated probe and laboratory-derived Staphylococcus mucus that are (i) defective in both FnBPA and FnBPB (fnbA fnbB double mutant, DU5883), (ii) capable of expressing only FnBPA (fnbA double mutant complemented with pFNBA4), or (iii) capable of expressing only FnBPB (fnbA fnbB double mutant complemented with pFNBB4). These experiments were repeated using Lactococcus lactis constructs expressing fnbA and fnbB genes from S. aureus. A distinct force signature was observed for those bacteria that expressed FnBPA or FnBPB. Analysis of this force signature with the biomechanical wormlike chain model suggests that parallel bonds form between fibronectin and FnBPs on a bacterium. The strength and covalence of bonds were evaluated via nonlinear regression of force profiles. Binding events were more frequent (p < 0.01) for S. mucus. expressing FnBPA or FnBPB than for the S. mucus double mutant. The binding force, frequency, and profile were similar between the FnBPA and FnBPB expressing strains of S. aureus. The absence of both FnBPs from the surface of S. amens removed its ability to form a detectable bond with fibronectin. By contrast, ectopic expression of FnBPA or FnBPB on the surface of L. lactis conferred fibronectin binding characteristics similar to those of S. amens. These measurements demonstrate that fibronectin-binding adhesins FnBPA and FnBPB are necessary and sufficient for the binding of S. aureus to prosthetic devices that are coated with host fibronectin.

AB Induced expression of neuroprotective genes is essential for maintaining neuronal integrity after stressful insults to the brain. Here we show that NR4A nuclear orphan receptors are induced after excitotoxic and oxidative stress in neurons, up-regulate neuroprotective genes, and increase neuronal survival. Moreover, we show that NR4A proteins are induced by cAMP response element binding protein (CREB) in neurons exposed to stressful insults and that they function as mediators of CREB-induced neuronal survival. Animals with null mutations in three of six NR4A alleles show increased oxidative damage, blunted induction of neuroprotective genes, and increased vulnerability in the hippocampus after treatment with kainic acid. We also demonstrate that NR4A and the transcriptional coactivator PGC-1 alpha independently regulate distinct CREB-dependent neuroprotective gene programs. These data identify NR4A nuclear orphan receptors as essential mediators of neuroprotection after exposure to neuropathological stress.

AB Expression of the regulatory T (T reg) cell-associated transcription factor Foxp3 can be induced by signals from the T cell receptor (TCR), interleukin-2 (IL-2), and transforming growth factor (TGF)-beta. These signals are integrated by a network involving phosphatidylinositol 3 kinase (PI3K), protein kinase B (PKB; here referred to as Akt), and the mammalian target of rapamycin (mTOR). New studies show that the Foxo proteins Foxo1 and Foxo3a, which are inactivated by Akt, drive Foxp3 expression. These studies therefore explain the negative regulation of Foxp3 by PI3K signaling, and add Foxo proteins to the growing list of nuclear factors capable of modulating Foxp3 expression.

AB Ataxia telangiectasia mutated (ATM) deficiency predisposes humans and mice to T lineage lymphomas with recurrent chromosome 14 translocations involving the T cell receptor alpha/delta (Tcra/d) locus. Such translocations have been thought to result from aberrant repair of DNA double-strand breaks (DSBs) during Tcra locus V(D)J recombination, and to require the Tcra enhancer (E.) for Tcra rearrangement or expression of the translocated oncogene. We now show that, in addition to the known chromosome 14 translocation, ATM-deficient mouse thymic lymphomas routinely contain a centromeric fragment of chromosome 14 that spans up to the 5' boundary of the Tcra/d locus, at which position a 500-kb or larger region centromeric to Tcra/d is routinely amplified. In addition, they routinely contain a large deletion of the telomeric end of one copy of chromosome 12. In contrast to prior expectations, the recurrent translocations and amplifications involve VD)J recombination-initiated breaks in the Tcrd locus, as opposed to the Tcra locus, and arise independently of the E alpha. Overall, our studies reveal previously unexpected mechanisms that contribute to the oncogenic transformation of ATM-deficient T lineage cells.

AB The transcription factor Foxp3 is essential for optimal regulatory T (T reg) cell development and function. Here, we show that CD4(+) T cells from Cbl-b RING finger mutant knockin or Cbl-b-deficient mice show impaired TGF-beta-induced Foxp3 expression. These T cells display augmented Foxo3a phosphorylation, but normal TGF-beta signaling. Expression of Foxo3a rescues Foxp3 expression in Cbl-b-deficient T cells, and Foxo3a deficiency results in defective TGF-beta-driven Foxp3 induction. A Foxo3a-binding motif is present in a proximal region of the Foxp3 promoter, and is required for Foxo3a association. Foxo1 exerts similar effects as Foxo3a on Foxp3 expression. This study reveals that Foxo factors promote transcription of the Foxp3 gene in induced T reg cells, and thus provides new mechanistic insight into Foxo-mediated T cell regulation.

AB The contribution of B cells to the pathology of Omenn syndrome and leaky severe combined immunodeficiency (SCID) has not been previously investigated. We have studied a mut/mut mouse model of leaky SCID with a homozygous Rag1 S723C mutation that impairs, but does not abrogate, V(D)J recombination activity. In spite of a severe block at the pro-B cell stage and profound B cell lymphopenia, significant serum levels of immunoglobulin (Ig) G, IgM, IgA, and IgE and a high proportion of Ig-secreting cells were detected in mut/mut mice. Antibody responses to trinitrophenyl (TNP)-Ficoll and production of high-affinity antibodies to TNP-keyhole limpet hemocyanin were severely impaired, even after adoptive transfer of wild-type CD4(+) T cells. Mut/mut mice produced high amounts of low-affinity self-reactive antibodies and showed significant lymphocytic infiltrates in peripheral tissues. Autoantibody production was associated with impaired receptor editing and increased serum B cell-activating factor (BAFF) concentrations. Autoantibodies and elevated BAFF levels were also identified in patients with Omenn syndrome and leaky SCID as a result of hypomorphic RAG mutations. These data indicate that the stochastic generation of an autoreactive B cell repertoire, which is associated with defects in central and peripheral checkpoints of B cell tolerance, is an important, previously unrecognized, aspect of immunodeficiencies associated with hypomorphic RAG mutations.

ID NERVE-FIBER LAYER; BIREFRINGENCE; COLLAGEN
AB We present in-vivo 3D human vocal fold images with polarization sensitive optical coherence tomography (PS-OCT). Characterizing the extent and location of vocal fold lesions provides useful information in guiding surgeons during phonomicrosurgery. Previous studies showed that PS-OCT imaging can distinguish vocal fold lesions from normal tissue, but these studies were limited to 2D cross-sectional imaging and were susceptible to sampling error. In-vivo 3D endoscopic imaging was performed by using a recently developed 2-axis MEMS scanning catheter and a spectral domain OCT (SD-OCT), running at 18.5 frames/s. Imaging was performed in the operating room with patients under general anesthesia and 3D images were acquired either by 2D scanning of the scanner on the sites of interest or by combining 1D scanning and manual sliding to capture whole length of the vocal fold. Vocal fold scar, polyps, nodules, papilloma and malignant lesions were imaged and characteristics of individual lesions were analyzed in terms of spatial distribution and variation of tissue structure and birefringence. The 3D large sectional PS-OCT imaging showed that the spatial extent of vocal fold lesions can be found non-invasively with good contrast from normal tissue. (C) 2010 Optical Society of America

AB Antiretroviral therapy of HIV infection has changed a uniformly fatal into a potentially chronic disease. There are now 17 drugs in common use for HIV treatment. Patients who can access and adhere to combination therapy should be able to achieve durable, potentially lifelong suppression of HIV replication. Despite the unquestioned success of antiretroviral therapy, limitations persist. Treatment success needs strict lifelong drug adherence. Although the widely used drugs are generally well tolerated, most have some short-term toxic effects and all have the potential for both known and unknown long-term toxic effects. Drug and administration costs limit treatment in resource-poor regions, and are a growing concern even in resource rich settings. Finally, complete or near complete control of viral replication does not fully restore health. Long-term treated patients who are on an otherwise effective regimen often show persistent immune dysfunction and have higher than expected risk for various non-AIDS-related complications, including heart, bone, liver, kidney, and neurocognitive diseases.

TI HSPC117 deficiency in cloned embryos causes placental abnormality and

AB Somatic cell nuclear transfer (SCNT) has been successfully used in many species to produce live cloned offspring, albeit with low efficiency. The low frequency of successful development has usually been ascribed to incomplete or inappropriate reprogramming of the transferred nuclear genome. Elucidating the genetic differences between normal fertilized and cloned embryos is key to understand the low efficiency of SCNT. Here, we show that expression of HSPC117, which encodes a hypothetical protein of unknown function, was absent or very low in cloned mouse blastocysts. To investigate the role of HSPC117 in embryo development, we knocked-down this gene in normal fertilized embryos using RNA interference. We assessed the post-implantation survival of HSPC117 knock-down embryos at 3 stages: E9 (prior to placenta formation); E12 (after the placenta was fully functional) and E19 (post-natal). Our results show that, although siRNA-treated in vivo fertilized/produced (IVP) embryos could develop to the blastocyst stage and implanted without any difference from control embryos, the knock-down embryos showed substantial fetal death, accompanied by placental blood clotting, at E12. Furthermore, comparison of HSPC117 expression in placentas of nuclear transfer (NT), intracytoplasmic sperm injection (ICSI) and IVP embryos confirmed that HSPC117 deficiency correlates well with failures in embryo development: all NT embryos with a fetus, as well as IVP and ICSI embryos, had normal placental HSPC117 expression while those NT embryos showing reduced or no expression of HSPC117 failed to form a fetus. In conclusion, we show that HSPC117 is an important gene for post-implantation development of embryos, and that HSPC117 deficiency leads to fetal abnormalities after implantation, especially following placental formation. We suggest that defects in HSPC117 expression may be an important contributing factor to loss of cloned NT embryos in vivo. (C) 2010 Elsevier Inc. All rights reserved.

AB Two independent studies by Li et al. (2010) and Samavarchi-Tehrani et al. (2010) in this issue of Cell Stem Cell suggest that a mesenchymal-to-epithelial transition is a critical initiating event during the derivation of induced pluripotent stem cells (iPSCs) from fibroblasts, indicating remarkable similarities between cellular reprogramming, development, and cancer.

AB Successful cancer therapy requires the elimination or incapacitation of all tumor cells capable of regenerating a tumor. Therapeutic advances therefore necessitate the characterization of the cells that are able to propagate a tumor in vivo. We show an important link between tumor genotype and isolation of tumor-propagating cells (TPCs). Three mouse models of the most common form of human lung cancer each had TPCs with a unique cell-surface phenotype. The cell-surface marker Sca1 did not enrich for TPCs in tumors initiated with oncogenic Kras, and only Sca1-negative cells propagated EGFR mutant tumors. In contrast, Sca1-positive cells were enriched for tumor-propagating activity in Kras tumors with p53 deficiency. Primary tumors that differ in genotype at just one locus can therefore have tumor-propagating cell populations with distinct markers. Our studies show that the genotype of tumor samples must be considered in studies to identify, characterize, and target tumor-propagating cells.

AB Phosphorylation of H2AX functions to recruit DNA repair complexes to sites of DNA damage. Here, we report that H2AX is constitutively acetylated on lysine 36 (H2AXK36Ac) by the CBP/p300 acetyltransferases. H2AXK36Ac is required for cells to survive exposure to ionizing radiation; however, H2AXK36Ac levels are not increased by DNA damage. Further, acetylation of H2AX did not affect phosphorylation of H2AX or the formation of DNA damage foci. Finally, cells with a double mutation in both the H2AX acetylation and phosphorylation sites were more radiosensitive than cells containing individual mutations. H2AXK36Ac is therefore a novel, constitutive histone modification located within the histone core region which regulates radiation sensitivity independently of H2AX phosphorylation.

TI Effective Post-insult Neuroprotection by a Novel

DEPRIVATION
AB Ca2+/calmodulin (CaM)-dependent protein kinase II (CaMKII) is a major mediator of physiological glutamate signaling involved in higher brain functions. Here, we show CaMKII involvement in pathological glutamate signaling relevant in stroke. The novel inhibitor tatCN21 was neuroprotective even when added hours after glutamate insults. By contrast, the "traditional" inhibitor KN93 attenuated excitotoxicity only when present during the insult. Both inhibitors efficiently blocked Ca2+/CaM-stimulated CaMKII activity, CaMKII interaction with NR2B and aggregation of CaMKII holoenzymes. However, only tatCN21 but not KN93 blocked the Ca2+-independent "autonomous" activity generated by Thr-286 autophosphorylation, the hallmark feature of CaMKII regulation. Mutational analysis further validated autonomous CaMKII activity as the drug target crucial for post-insult neuroprotection. Overexpression of CaMKII wild type but not the autonomy-deficient T286A mutant significantly increased glutamate-induced neuronal death. Maybe most importantly, tatCN21 also significantly reduced infarct size in a mouse stroke model (middle cerebral arterial occlusion) when injected (1 mg/kg intravenously) 1 h after onset of arterial occlusion. Together, these data demonstrate that inhibition of autonomous CaMKII activity provides a promising therapeutic avenue for post-insult neuro-protection after stroke.

AB The introduction of all-hydrocarbon i,i+3 staples into alpha-helical peptide scaffolds via ring-closing olefin metathesis (RCM) between two alpha-methyl,alpha-pentenylglycine residues incorporated at i and i+3 positions, which lie on the same face of the helix, has been investigated. The reactions were found to be highly dependent upon the side-chain stereochemistry of the amino acids undergoing RCM. The i,i+3 stapling system established here provides a potentially useful alternative to the well-established i,i+4 stapling system now in widespread use.

TI Successful Self-Directed Lifelong Learning in Medicine: A Conceptual
Model Derived From Qualitative Analysis of a National Survey of
Pediatric Residents
SO ACADEMIC MEDICINE
LA English
DT Article
ID PHYSICIAN CHARTER; PROFESSIONALISM; MILLENNIUM; EDUCATION
AB Purpose Self-directed lifelong learning is integral to medical professionalism, yet how best to encourage its development during clinically intensive training is unknown. The authors develop a model for successful self-directed learning by analyzing qualitative data from a national survey of residents.
Method Pediatric and medicine/pediatric residents at 46 training programs completed a Web-based survey in 2008-2009. Self-reported barriers to and strategies for achieving self-directed learning goals were systematically analyzed through inductive iterative review.
Results A total of 992 out of 1,739 (57%) residents responded. Barriers to achieving self-directed learning goals were categorized into difficulty with personal reflection, environmental strain, competing demands, difficulty with goal generation, and problems with plan development and implementation. Strategies for achieving learning goals included creating goals that were important (relevant to the learner and prioritized by the learner as important to achieve), specific (with broad goals broken down into incremental steps and a specific plan for each step), measurable, accountable (with reminder and tracking systems and building in internal and external accountability), realistic (achievable goals which utilize existing opportunities and constant self-adjustment), and included a timeline for completing the goal (and incorporating the goal into their daily routine).
Conclusions On the basis of the data, the authors propose a conceptual model for self-directed lifelong learning involving creation of learning goals and plan development based on individual reflection and self-assessment, and continual revision of goals and/or plans based on degree of goal attainment. This model could be broadly applicable throughout medical education.

TI Therapy 101: A Psychotherapy Curriculum for Medical Students
SO ACADEMIC PSYCHIATRY
LA English
DT Article
AB Objective: This pilot project, designed and taught by a resident, created a curriculum to introduce medical students to the practice of psychotherapy. Medical students who are knowledgeable about psychotherapy can become physicians who are able to refer patients to psychotherapeutic treatments. A search of the literature did not identify a curriculum that introduced psychotherapy, its applications, and evidence for its use.
Methods: The authors worked closely with a faculty mentor to create a course that fulfilled a perceived need for more psychotherapy teaching of medical students. "Therapy 101: An Introduction to Psychotherapy" is a 6-hour curriculum that employs creative teaching techniques such as video clips from TV shows, role play, and recordings of therapy sessions. The series was evaluated using a multiple-choice pre/postcourse test with questions on psychotherapy, written feedback, and perceived knowledge of psychotherapy.
Results: The scores from the pre/postcourse test measuring the students' knowledge of psychotherapy did not change significantly. However, students' self-rating of knowledge greatly increased after the series. Written feedback showed substantial enthusiasm for the course.
Conclusion: Students can benefit from a short and engaging curriculum on psychotherapy. "Therapy 101" was very well accepted by students and has been integrated into the curriculum for students in the mental health pathway. Medical students may benefit from more exposure to psychotherapy as taught by a resident.

AB Post-operative cognitive dysfunction (POCD) is a decline in cognitive function from pre-operative levels, which has been frequently described after cardiac surgery. The purpose of this study was to examine the variability in the measurement and definitions for POCD using the framework of a 1995 Consensus Statement on measurement of POCD. Electronic medical literature databases were searched for the intersection of the search terms 'thoracic surgery' and 'cognition, dementia, and neuropsychological test.' Abstracts were reviewed independently by two reviewers. English articles with > 50 participants published since 1995 that performed pre-operative and post-operative psychometric testing in patients undergoing cardiac surgery were reviewed. Data relevant to the measurement and definition of POCD were abstracted and compared with the recommendations of the Consensus Statement. Sixty-two studies of POCD in patients undergoing cardiac surgery were identified. Of these studies, the recommended neuropsychological tests were carried out in less than half of the studies. The cognitive domains measured most frequently were attention (n=56; 93%) and memory (n=57; 95%); motor skills were measured less frequently (n=36; 60%). Additionally, less than half of the studies examined anxiety and depression, performed neurological exam, or accounted for learning. Four definitions of POCD emerged: per cent decline (n=15), standard deviation decline (n=14), factor analysis (n=13), and analysis of performance on individual tests (n=12). There is marked variability in the measurement and definition of POCD. This heterogeneity may impede progress by reducing the ability to compare studies on the causes and treatment of POCD.

AB Conclusions: Selecting patients that are candidates for surgical treatment is important in the work-up of patients with tracheal cancer. Toward this goal, centralization of care concerning tracheal tumors is advised. Centralization may increase long-term survival and decrease operative morbidity and mortality even further. Objective: Primary tracheal tumors pose a diagnostic and therapeutic challenge for the physician when confronted with this mostly malignant tumor. Diagnosis is often delayed for months or years due to its aspecific and asthma-mimicking symptoms. Knowledge from retrospective series is limited and few clinicians have gained experience with this tumor. The available literature on the diagnosis and management of this group of tumors is reviewed to summarize the available knowledge about these uncommon tumors. New diagnostic, staging, and treatment guidelines are proposed. Methods: PubMed was searched for English publications from 1960. The available literature was reviewed and summarized. Results: Surgical resection and primary reconstruction is the best curative treatment modality available at present. In centers of experience, more than half of all patients with tracheal cancer may be candidates for surgical resection, although in population-based studies this treatment is applied in only 10-25% of patients.

AB Neuroadaptations supporting behavioral sensitization to abused drugs are suggested to underlie pathological, excessive motivation toward drugs and drug-associated stimuli. Drug-induced sensitization has also been linked to increased appetitive responses for non-drug, natural reinforcers. The present research investigated whether ethanol (EtOH)-induced neural changes, inferred from psychomotor sensitization, can modify consumption and intake dynamics for the natural reinforcer, sucrose. The effects of EtOH-induced sensitization in mice on the temporal structure of sucrose intake patterns were measured using a lickometer system. After sensitization, sucrose intake dynamics were measured for 1 hour daily for 7 days and indicated more rapid initial approach and consumption of sucrose in EtOH-sensitized groups; animals showed a shorter latency to the first intake bout and an increased number of sucrose bottle licks during the initial 15 minutes of the 1-hour sessions. This effect was associated with increased frequency and size of bouts. For the total 1-hour session, sucrose intake and bout dynamics were not different between groups, indicating a change in patterns of sucrose intake but not total consumption. When sensitization was prevented by the gamma-aminobutyric acid B receptor agonist, baclofen, the increased rate of approach and consumption of sucrose were also prevented. Thus, EtOH-induced sensitization, and not the mere exposure to EtOH, was associated with changes in sucrose intake patterns. These data are consistent with current literature suggesting an enhancing effect of drug-induced sensitization on motivational processes involved in reinforcement.

AB Tumors of the thyroid are subclassified based on the cell of origin and commonly include follicular-derived tumors and C-cell-derived tumors. The most common follicular-derived tumors are papillary carcinoma and follicular carcinoma, whereas the malignant C-cell-derived tumor is medullary thyroid carcinoma. Rare cases in the literature describe patients who have follicular-derived and C-cell-derived tumors in the same thyroid gland. These can be synchronous but anatomically separate carcinomas, or they can show some mixing of the 2 components. The mixture may be at an interface, as in collision tumors, or can be throughout the entire lesion, as in true mixed medullary-follicular-derived carcinomas. The clinical, histologic, and molecular features of these mixed tumors and the classification guidelines are reviewed.

AB Age-associated loss of kidney function has been recognized for decades. With aging, many subjects exhibit progressive decreases in glomerular filtration rate and renal blood flow, with wide variability among individuals. The fall in glomerular filtration rate is because of reductions in the glomerular capillary plasma flow rate and the glomerular capillary ultrafiltration coefficient. In addition, a primary reduction in afferent arteriolar resistance is associated with an increase in glomerular capillary hydraulic pressure. These hemodynamic changes occur in concert with structural changes, including loss of renal mass; hyalinization of afferent arterioles and in some cases, development of aglomerular arterioles; an increase in the percentage of sclerotic glomeruli; and tubulointerstitial fibrosis. Aging is associated with altered activity and responsiveness to vasoactive stimuli, such that responses to vasoconstrictor stimuli are enhanced, whereas vasodilatory responses are impaired. Changes in the activity of the renin-angiotensin and nitric oxide systems appear to be particularly important, as is the modulating effect of gender. These changes may predispose the older kidney to acute kidney injury, including normotensive ischemic nephropathy, as well as progressive chronic kidney disease.

AB As the population of the United States ages, the prevalence of age-related chronic conditions such as hypertension and chronic kidney disease (CKD) will also increase. Available studies in nationally representative samples and select outpatient populations indicate that hypertension is very common in older adults with CKD, and despite the use of medication it is often poorly controlled. Generally, less than one-third of the elderly patients with CKD achieve a level of blood pressure control consistent with that of the current guideline recommendations. However, limited evidence is available from observational studies and clinical trials to inform management of hypertension in the elderly population with CKD. The available published data suggest that the relationship between clinical outcomes and the treatment of hypertension among older adults with CKD is complex and distinct from that of their younger counterparts. Larger and more robust analyses are needed for a better understanding of the association between hypertension, its treatment, and clinical events in elderly patients with CKD.

TI Cost of Rapid HIV Testing at 45 US Hospitals

DT Article
ID UNITED-STATES; EMERGENCY; SETTINGS
AB In 2006, the United States Centers for Disease Control and Prevention (CDC) recommended expanded and routine use of single-session rapid HIV tests in all health care settings to increase the proportion of persons who learn their HIV status. Limited empiric information is available regarding the costs of rapid testing and pre- and posttest counseling in health care settings. We surveyed 45 U. S. hospitals during 2005 through 2006 to assess the costs associated with rapid testing and counseling. Cost analyses were conducted from the provider (hospital) perspective, and results were expressed in year 2006 U. S. dollars. The mean per-test cost of rapid HIV testing and counseling was $48.07 for an HIV-negative test and $64.17 for a preliminary-positive test. Pre- and posttest counseling costs accounted for 38.4% of the total cost of rapid testing for HIV-negative patients. Counseling costs were significantly correlated with overall test costs. Many hospitals contained overall test costs by limiting time spent in pre- and posttest counseling or by using lower-paid personnel for counseling activities or both. Counseling costs constituted a significant proportion of the overall costs of rapid testing and counseling activities at study hospitals. Our data provide useful baseline data before implementation of the CDC's 2006 recommendations. Costs can be reduced by limiting time spent in pre- and posttest counseling or by using lower-paid personnel for counseling activities or both.

AB Mistrust among African Americans is often considered a potential source of racial disparities in HIV care. We sought to determine whether greater trust in one's provider among African-American patients mitigates racial disparities. We analyzed data from 1,104 African-American and 201 white patients participating in a cohort study at an urban, academic HIV clinic between 2005 and 2008. African Americans expressed lower levels of trust in their providers than did white patients (8.9 vs. 9.4 on a 0-10 scale; p<0.001). African Americans were also less likely than whites to be receiving antiretroviral therapy (ART) when eligible (85% vs. 92%; p = 0.02), to report complete ART adherence over the prior 3 days (83% vs. 89%; p = 0.005), and to have a suppressed viral load (40% vs. 47%; p = 0.04). Trust in one's provider was not associated with receiving ART or with viral suppression but was significantly associated with adherence. African Americans who expressed less than complete trust in their providers (0-9 of 10) had lower ART adherence than did whites (adjusted OR, 0.40; 95% CI, 0.25-0.66). For African Americans who expressed complete trust in their providers (10 of 10), the racial disparity in adherence was less prominent but still substantial (adjusted OR, 0.59; 95% CI, 0.36-0.95). Trust did not affect disparities in receipt of ART or viral suppression. Our findings suggest that enhancing trust in patient-provider relationships for African-American patients may help reduce disparities in ART adherence and the outcomes associated with improved adherence.

AB Background Changes in gastric histology associated with long-term maintenance therapy with lansoprazole for erosive oesophagitis have not been well described.
Aim To evaluate the effect on gastric histology of long-term dose-titrated lansoprazole administered as maintenance therapy for up to 82 months in patients with erosive oesophagitis.
Methods Sequential gastric biopsy specimens were obtained for evaluation of histological changes and Helicobacter pylori infection status.
Results Active and chronic inflammation improved from baseline to final visit in a majority of patients receiving long-term therapy with lansoprazole, irrespective of baseline H. pylori infection status. Reductions in active inflammation in the gastric body and antrum were seen in 53% (17/32) and 67% (20/30) of H. pylori-positive patients, respectively, and in 88% (7/8) and 86% (12/14) of H. pylori-negative patients, respectively. Reductions in chronic inflammation in the gastric body and antrum were seen in 38% (12/32) and 47% (15/32) of H. pylori-positive patients, respectively, and in 58% (70/121) and 57% (68/120) of H. pylori-negative patients, respectively. No clinically meaningful increases in hyperplasia, dysplasia, neoplasia, intestinal metaplasia or atrophy were observed during the follow-up period.
Conclusions Lansoprazole administered as maintenance therapy for up to 6 years in patients with erosive oesophagitis demonstrated gastric mucosal safety and was well tolerated. Aliment Pharmacol Ther 2010; 32: 83-96

AB The goal of managing asthma is to maintain disease control. Current approaches to assessment of control do not include measurement of airway inflammation. This study was designed to assess the usefulness of biomarkers of airway inflammation in guiding asthma management decisions. A literature review was performed. Bronchial biopsy is a direct measure of airway inflammation but not practical for routine use. Enumeration of sputum eosinophils is very useful in guiding changes in controller medication to decrease asthma exacerbations, whereas measurement of exhaled nitric oxide has not proven to be useful in this regard. Serial measurement of airway hyperreactivity as a guide to asthma management yields inconclusive results. Use of indirect stimuli for bronchial challenge offers both practical and theoretical advantages in the assessment of airway hyperreactivity. Data on the analysis of exhaled breath condensate have not yet been studied adequately in guiding management decisions. Enumeration of sputum cell counts appears to be the most useful biomarker of airway inflammation in guiding asthma management decisions. Combined approaches using simple methods of measuring airway hyperreactivity and obtaining sputum samples hold promise for the future, particularly if rapid analysis of cellular products in sputum can be developed.

AB The epinephrine auto-injector has been widely used over a long period of time. Certain aspects of this therapy and demographic data, however, have not been well studied. This study investigates patient use and understanding of epinephrine auto-injector use. As part of an ongoing quality assurance program, we evaluated 66 patients who had been given an epinephrine auto-injector and followed in the Allergy and Immunology Clinics at the West Los Angeles Veterans Medical Center. Data analyzed included patient demographics, medical indications for epinephrine auto-injector prescriptions, and the patient's understanding and use of the device. The mean age of our patients was 50 years. There were 44 men (66.7%) and 22 women (33%). Twenty-three patients were prescribed epinephrine auto-injector for adverse food reactions. Ninety-two percent (92%) of the patients knew how to use their epinephrine auto-injector properly, however, only 58% carried their device with them consistently. Of the patients, 91% understood why the auto-injector was prescribed. Of the total patients prescribed epinephrine auto-injector, 79% refilled their medication before the 1 year expiratidn date. Only 12% of the patients studied had required the use of their auto-injector. Most patients knew how and when to administer their epinephrine auto-injector. Despite detailed instructions in a specialty clinic only a slight majority carried it consistently. These data clearly indicate that further patient education or other measures are needed to improve compliance and effective use. (Allergy Asthma Proc 31:304-307, 2010; doi: 10.2500/aap.2010.31.3351)

AB To date, there are sparse data on epinephrine treatment for food-related anaphylaxis in adults. We sought to establish the frequency of more than one epinephrine treatment for adult patients who present with food-related anaphylaxis to the emergency department (ED). We performed a chart review, at two academic centers, of all adults presenting to the ED for food allergy (ICD9CM codes 693.1, 995.0, 995.1, 995.3, 995.7, 995.60-995.69, 558.3, 692.5, and 708.X) between January 1, 2001 and December 31, 2006. We focused on causative foods; treatments, including the number of epinephrine treatments given before and during the ED visit; and disposition. Through random sampling and appropriate weighting, the 486 reviewed cases represented a study cohort of 1286 patients. The median age was 36 years and the cohort was 62% women. Shellfish (23%), peanuts (12%), tree nuts (14%), and fish (14%) provoked the allergic reaction most commonly. Most patients (62%; 95% confidence interval [CI], 57-68%) met criteria for food-related anaphylaxis. In the ED, anaphylaxis patients received epinephrine (18%), antihistamines (91%), corticosteroids (81%), and inhaled albuterol (19%). Overall, 17% (95% CI, 9-25%) of patients with food-related anaphylaxis given epinephrine received >1 dose over the course of their reaction. Among anaphylaxis patients admitted to the hospital, only 10% included anaphylaxis in the discharge diagnosis. At ED discharge (82% of patients), 18% were referred to an allergist and 39% were prescribed self-injectable epinephrine. Among ED patients with food-related anaphylaxis treated with epinephrine, 17% were given >1 dose. This study supports the recommendation that patients at risk for food-related anaphylaxis should carry 2 doses of epinephrine. (Allergy Asthma Proc 31:308-316, 2010; doi: 10.2500/aap.2010.31.3375)

AB Preclinical and epidemiologic studies suggest a protective effect of statins on Alzheimer disease (AD). Experimental evidence indicates that some statins can cross the blood-brain barrier, alter brain cholesterol metabolism, and may ultimately decrease the production of amyloid-beta (A beta) peptide. Despite these promising leads, clinical trials have yielded inconsistent results regarding the benefits of statin treatment in AD. Seeking to detect a biological signal of statins effect on AD, we conducted a 12-week open-label trial with simvastatin 40 mg/d and then 80 mg/d in 12 patients with AD or amnestic mild cognitive impairment and hypercholesterolemia. We quantified cholesterol precursors and metabolites and AD biomarkers of A beta and tau in both plasma and cerebrospinal fluid at baseline and after the 12-week treatment period. We found a modest but significant inhibition of brain cholesterol biosynthesis after simvastatin treatment, as indexed by a decrease of cerebrospinal fluid lathosterol and plasma 24S-hydroxycholesterol. Despite this effect, there were no changes in AD biomarkers. Our findings indicate that simvastatin treatment can affect brain cholesterol metabolism within 12 weeks, but did not alter molecular indices of AD pathology during this short-term treatment.

AB This report describes a pilot study to evaluate feasibility of new home-based assessment technologies applicable to clinical trials for prevention of cognitive loss and Alzheimer disease. Methods: Community-dwelling nondemented individuals >= 75 years old were recruited and randomized to 1 of 3 assessment methodologies: (1) mail-in questionnaire/ live telephone interviews (MIP); (2) automated telephone with interactive voice recognition (IVR); and (3) internet-based computer Kiosk (KIO). Brief versions of cognitive and noncognitive outcomes were adapted to the different methodologies and administered at baseline and 1-month. An Efficiency measure, consisting of direct staff-to-participant time required to complete assessments, was also compared across arms. Results: Forty-eight out of 60 screened participants were randomized. The dropout rate across arms from randomization through 1-month was different: 33% for KIO, 25% for IVR, and 0% for MIP (Fisher Exact Test P = 0.04). Nearly all participants who completed baseline also completed 1-month assessment (38 out of 39). The 1-way ANOVA across arms for total staff-to-participant direct contact time (ie, training, baseline, and 1-month) was significant: F (2,33) = 4.588; P = 0.017, with lowest overall direct time in minutes for IVR (Mn - 44.4; SD = 21.5), followed by MIP (Mn = 74.9; SD = 29.9), followed by KIO (Mn = 129.4; SD = 117.0). Conclusions: In this sample of older individuals, a higher dropout rate occurred in those assigned to the high-technology assessment techniques; however, once participants had completed baseline in all 3 arms, they continued participation through 1 month. High-technology home-based assessment methods, which do not require live testers, began to emerge as more time-efficient over the brief time of this pilot, despite initial time-intensive participant training.

AB Despite current dual-antiplatelet therapy with aspirin and clopidogrel, adverse clinical events continue to occur during and after percutaneous coronary intervention (PCI). The failure of clopidogrel to provide optimal protection may be related to delayed onset of action, interpatient variability in its effect, and an insufficient level of platelet inhibition. Furthermore, the irreversible binding of clopidogrel to the P2Y(12) receptor for the life span of the platelet is associated with increased bleeding risk especially during urgent or emergency surgery. Novel antiplatelet agents are required to improve management of patients undergoing PCI. Elinogrel is a potent, direct-acting (ie, non-prodrug), selective, competitive, and reversible P2Y(12) inhibitor available in both intravenous and oral formulations. The INNOVATE-PCI study is a phase 2 randomized, double-blind, clopidogrel-controlled trial to evaluate the safety, tolerability, and preliminary efficacy of this novel antiplatelet agent in patients undergoing nonurgent PCI.

AB Background Expanding insurance coverage, while necessary, may not be sufficient to ensure high-quality care for adults with cardiovascular disease. We sought to examine the association between having a usual source of care (USOC) and receiving medication treatment of hypertension and hypercholesterolemia.
Methods Using the 2003-2006 National Health and Nutrition Examination Survey, we categorized USOC (a place to go when sick or need medical advice) and insurance status in adults >= 35 years old with an indication for medication treatment of hypertension (n = 3,142) and hypercholesterolemia (n = 1,134), determined using the Joint National Committee 7 and Adult Treatment Panel III recommendations, respectively. Multivariable logistic regression modeling was used to determine the independent effect of USOC on receiving treatment of hypertension and hypercholesterolemia, controlling for age, sex, race/ethnicity, insurance status, and comorbidities. Separate multivariable models were examined stratified by insurance status.
Results Among subjects with an indication for treatment of hypertension and hypercholesterolemia, 32.4% and 42.0% were untreated, respectively. When compared with adults with a USOC, adults without a USOC were more likely to be untreated for hypertension (adjusted prevalence ratio [aPR] 2.43, 95% CI 1.88-2.85) and hypercholesterolemia (aPR 1.79, 95% CI 1.31-2.13). In stratified analyses among subjects with insurance, no USOC remained associated with being untreated (hypertension, aPR 2.58, 95% CI 1.88-3.08; hypercholesterolemia, aPR 1.65, 95% CI 0.97-2.18).
Conclusions Absence of a USOC was associated with being untreated for hypertension and hypercholesterolemia, even among individuals with insurance, suggesting that efforts to improve chronic disease management should also facilitate access to a regular source of care.

AB Background Adherence to pharmacotherapy for heart failure is poor among older adults in part because of high prescription drug costs. We examined the impact of improvements in drug coverage under Medicare Part D on utilization of, and adherence to, medications for heart failure in older adults.
Methods We used a quasi-experimental approach to analyze pharmacy claims for 6,950 individuals aged >= 65 years with heart failure enrolled in a Medicare managed care organization 2 years before and after Part D's implementation. We compared prescription fill patterns among individuals who moved from limited (quarterly benefits caps of $150 or $350) or no drug coverage to Part D in 2006 with those who had generous employer-sponsored coverage throughout the study period.
Results Individuals who previously lacked drug coverage filled approximately 6 more heart failure prescriptions annually after Part D (adjusted ratio of prescription counts = 1.36, 95% CI 1.29-1.44, P < .0001 relative to the comparison group). Those previously lacking drug coverage were more likely to fill prescriptions for an angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker plus a beta-blocker after Part D (adjusted ratio of odds ratios = 1.73, 95% CI 1.42-2.10, P < .0001) and more likely to be adherent to such pharmacotherapy (adjusted ratio of odds ratios = 2.95, 95% CI 1.85-4.69, P < .0001) relative to the comparison group.
Conclusions Medicare Part D was associated with improved access to medications and adherence to pharmacotherapy in older adults with heart failure. (Am Heart J 2010; 160: 159-65.)

AB Young women hospitalized with acute myocardial infarction (MI) have greater in-hospital mortality than young men. However, the reasons for this difference have not been well characterized. We analyzed the data from 423,067 patients (247,701 men and 175,366 women) who were discharged with the diagnosis of MI from nonfederal hospitals in New Jersey and 355,569 coronary heart disease (CHD) deaths in New Jersey from 1990 to 2004 in 4 age strata: 35 to 54, 55 to 64, 65 to 74 and >= 75 years. Of the patients hospitalized for MI, young (35 to 54 years) women had greater in-hospital mortality than young men (5.2% vs 2.5%, adjusted odds ratio 1.64, 95% confidence interval 1.48 to 1.81, p <0.0001). However, in a community-wide analysis, when the total out-of-hospital CHD deaths in New Jersey were examined, young women had a lower out-of-hospital death rate than young men (11 vs 55/100,000). Statewide, young women were 4 times less likely to be hospitalized for MI (78 vs 297/100,000, relative risk 0.26), but they were only 1/2 as likely to die from MI in the hospital (7 vs 17/100,000, relative risk 0.41). Thus, women had a greater odds ratio for in-hospital mortality but a lower odds ratio for out-of-hospital CHD death than men. In conclusion, the greater in-hospital mortality of young women hospitalized for MI compared to young men could be explained in part by the finding that young men were more likely to have out-of-hospital CHD death.

TI Comparison of the Accuracy of Multidetector Computed Tomography Versus
Two-Dimensional Echocardiography to Measure Left Atrial Volume
SO AMERICAN JOURNAL OF CARDIOLOGY
LA English
DT Article
ID TIME 3-DIMENSIONAL ECHOCARDIOGRAPHY; SIZE
AB Left atrial (LA) volume is an important prognostic factor in cardiovascular disease. Multidetector computed tomography (MDCT) is an emerging cardiac imaging modality; however, its accuracy in measuring the LA volume has not been well studied. The aim of our study was to determine the accuracy of MDCT in quantifying the LA volume. A total of 48 patients underwent MDCT and 2-dimensional (2D) echocardiography (2DE) on the same day. The area length and Simpson's methods were used to obtain the 2D echocardiographic LA volume. The LA volume assessment by MDCT was obtained using the modified Simpson's method. Four artificial phantoms were created, and their true volume was assessed by an independent observer using both imaging modalities. The correlation between the LA volume by MDCT and 2DE was significant (r = 0.68). The mean 2D echocardiographic LA volume was lower than the LA volume obtained with MDCT (2DE 79 +/- 37 vs MDCT 103 +/- 32, p <0.05). In the phantom experiment, the volume obtained using MDCT and 2DE correlated significantly with the true volume (r = 0.97, p <0.05 vs r = 0.96, p <0.05, respectively). However, the mean 2D echocardiographic phantom volume was 16% lower than the true volume (2DE, Simpson's method 53 +/- 24 vs the true volume 61 +/- 24, p <0.05). The mean volume calculated using MDCT did not differ from the true volume (MDCT 60 +/- 21 vs true volume 61 +/- 24, p = NS). 2DE appeared to systematically underestimate the LA volume compared to phantom and cardiac MDCT, suggesting that different normal cutoff values should be used for each modality. In conclusion, LA volume quantification using MDCT is an accurate and feasible method. (C) 2010 Elsevier Inc. All rights reserved. (Am J Cardiol 2010;106:104-109)

AB Human papillomavirus (HPV) testing is routinely performed on oropharyngeal carcinomas. We compared the Access Genetics (Minneapolis, MN) polymerase chain reaction (PCR) assay (AGPCR), DNA-DNA in situ hybridization (ISH; Ventana, Tucson, AZ), and HP V-16 E7 PCR amplification in consecutively accessioned oropharyngeal cancers. We tested 126 cases by both PCR methods; 102 were positive by either for a maximum positive rate (MPR) of 81.0%. Relative to the MPR, the sensitivities of AGPCR and E7 PCR were 90.2% and 72.5%, respectively. Of 17 AGPCR+ cases tested by ISH, 14/14 unequivocally positive/negative were concordant. All cases (97/97) positive by either PCR assay were positive for p16. There was no relationship between level of histologic differentiation and HPV status. ISH and AGPCR have comparable performance for the detection of HP V in orophatyngeal carcinomas. PCR is a suitable and economical assay that is comparable to ISH in sensitivity and may provide logistical advantages relative to ISH for assessing HPV status in orophatyngeal malignancies. However, it is imperative that appropriate sensitivity controls be in place for such assays.

TI D2-40 Expression in Primary Scarring and Nonscarring Alopecia
SO AMERICAN JOURNAL OF DERMATOPATHOLOGY
LA English
DT Article
DE alopecia; scarring; nonscarring; D2-40
ID BULGE REGION; PODOPLANIN; MARKER; CARCINOMAS; NESTIN; CELLS; SKIN
AB The pathogenesis of scarring alopecia is believed to be related to damage to stem cells within, and outside the confines of, the follicular bulge region. Scattered reports indicate that D2-40, a monoclonal antibody that specifically detects a fixation-resistant epitope on podoplanin, highlights the basal cell layer of the outer root sheath. Given this, we sought to ascertain involvement of the same in a total of 52 cases of alopecia (33 scarring and 19 nonscarring). D2-40 expression, noted in the peripheral layer of the outer root sheath (above and below attachment of the pilar muscle), was similar in 24/33 (73%) and increased in 9/33 (27%) in the infundibular region of cases of scarring alopecia in comparison to its expression in 17/19 (90%; no expression noted in the other 2) of cases of nonscarring alopecia. The absence of a unifying diagnosis in entities demonstrating an increase precludes any correlation from being made regarding D2-40 expression and histologic diagnosis. However, more recently, podoplanin has been shown to be a novel Fos target gene in some skin cancers. Thus, from a scientific perspective, involvement of Fos-dependent transcription mechanisms in the etiopathogenesis of select scarring alopecias does not seem entirely unreasonable although studies defining the role of the Fos-podoplanin axis in development of the normal hair follicle are required before a definitive conclusion can be drawn.

TI When Late-Life Depression Improves: What Do Older Patients Say About

ID GERIATRIC DEPRESSION; PRIMARY-CARE; RANDOMIZED-TRIAL; MIXED-METHODS;

AB Introduction: Experts speculate about the mechanisms through which depression interventions operate. However, little is known about what patients think are the "active ingredients" in depression treatment. Given the importance of patient-centered care, understanding this dimension of the provider-intervention-patient interaction provides a missing piece to designing interventions that are congruent with patients' beliefs and preferences about treatment initiation, treatment adherence, and treatment maintenance. Methods: The authors used a parallel mixed methods design to identify a purposive sample of 24 older adults with depression who participated in either an integrated care or an enhanced referral model of depression treatment. Open-ended semistructured interviews were used to identify patient perceptions about the benefits of depression treatment during the study. Quantitative assessments of depression status were made at the completion of participation in the treatment study and 6 months postparticipation. Results: Twelve of 24 participants achieved remission of their depression symptoms, with the remainder showing no improvement or a partial response to treatment. Participants who achieved and sustained a remission of their depression symptoms (N = 7) attributed their improvement to clear psychoeducational support with their depression care providers and described an ability to affect the outcome of their treatment. Participants who improved but then relapsed described their treatment in vague terms, referring to social aspects of participation. Participants who did not achieve remission ascribed recognition and treatment of their depression to forces outside themselves and described few details about their treatment. Conclusion: Clinicians should consider patient perceptions of the benefits of depression treatment as they discuss and implement therapeutic interventions with depressed older adults.

AB Objectives: Cortical systems involved in the response to medication treatment for Alzheimer's disease (AD) are poorly understood. Preclinical studies have demonstrated the effect of memantine on neuroreceptors and cell physiology, although the impact of treatment on cortical activity in vivo is not known. Design: (18)F-fluorodeoxyglucose positron emission tomography (PET) imaging and clinical assessment before and after open-label memantine treatment. Participants/Setting: Seventeen outpatients with probable AD on stable cholinesterase inhibitor medication. Intervention: Memantine up to 10 mg twice daily for 10 weeks. Measurements: Voxel-based analyses of change in cortical metabolic activity; Mattis Dementia Rating Scale (DRS), and Neurobehavioral Rating Scale (NRS). Results: Mean age was 81 years; mean Mini-Mental State Examination score was 19.4. Compared with baseline, metabolic activity was significantly higher after 10 weeks memantine treatment in two cortical regions bilaterally: the inferior temporal gyrus (BA 20) and the angular gyrus/supramarginal gyrus (BA 39, 40). There was no significant relationship between change in DRS score and change in cortical metabolism, although change in NRS score was associated with the extent of metabolic change in the right parietal and temporal cortex. Conclusion: Metabolic activity in bilateral inferior parietal and temporal cortex increases during 10 weeks of memantine treatment in patients with AD. PET imaging can reveal functional effects of medications on neural activity and may help to define critical mechanisms involved in drug treatment. (Am J Geriatr Psychiatry 2010; 18: 606-614)

AB Background: Because there is wide variation in outcomes across dialysis facilities, it is possible that top-performing units use practices not shared by others. The Identifying Best Practices in Dialysis (IBPiD) Study seeks to identify practices that distinguish top-from bottom-performing facilities by key outcomes, including achievement of recommended hemoglobin targets.
Study Design: Observational study with cross-sectional study ascertainment of predictors and outcomes.
Predictors: Facility dialysis practices ascertained using practice surveys of dialysis staff who indicated their level of agreement that each practice occurs in their facility (1-6 on a Likert scale).
Setting & Participants: 423 personnel in 90 dialysis facilities from 1 for-profit and 2 not-for-profit dialysis organizations.
Outcomes: Percentage of patients per month per facility with hemoglobin levels of 11-12 g/dL. We divided facilities by median into top-versus bottom-performing groups and compared mean scores for each practice using t tests. We report practices that were statistically significant and achieved at least a medium effect size (ES) >= 0.4.
Results: 17 of 155 tested predictors were significant. Achievement of hemoglobin level targets was related most strongly to the use of chairside computers (ES, 0.8 [95% CI, 0.4-1.4]), extent/quality of educational videos (ES, 0.6 [95% CI, 0.2-1.1]), frequency of calling per diem staff if short staffed (ES, 0.6 [95% CI, 0.21-1.1]), policy that nurses pass written competency examinations before hire (ES, 0.6 [95% CI, 0.2-1.0]), and technician cannulation mastery (ES, 0.6 [95% CI, 0.2-1.1]).
Limitations: This is a cross-sectional study that can address only associations, not causations. Future research should measure the longitudinal predictive value of these practices.
Conclusions: High-performing facilities report more effective education programs, better staff management, higher staff competency, and higher use of chairside computers, a potential marker of information technology proficiency. This suggests that hemoglobin level management is enhanced by processes reflecting a coordinated multidisciplinary environment. Am J Kidney Dis 56:86-94.

AB Objective: To estimate the economic value of preoperative methicillin-resistant Staphylococcus aureus (MRSA) screening and decolonization for cardiac surgery patients.
Study Design: Monte Carlo decision-analytic computer simulation model.
Methods: We developed a computer simulation model representing the decision of whether to perform preoperative MRSA screening and decolonizing those patients with a positive MRSA culture. Sensitivity analyses varied key input parameters including MRSA colonization prevalence, decolonization success rates, the number of surveillance sites, and screening/ decolonization costs. Separate analyses estimated the incremental cost-effectiveness ratio (ICER) of the screening and decolonization strategy from the third-party payer and hospital perspectives.
Results: Even when MRSA colonization prevalence and decolonization success rate were as low as 1% and 25%, respectively, the ICER of implementing routine surveillance was well under $ 15,000 per quality-adjusted life-year from both the third-party payer and hospital perspectives. The surveillance strategy was economically dominant (less costly and more effective than no testing) for most scenarios explored.
Conclusions: Our results suggest that routine preoperative MRSA screening of cardiac surgery patients could provide substantial economic value to third-party payers and hospitals over a wide range of MRSA colonization prevalence levels, decolonization success rates, and surveillance costs. Healthcare administrators, infection control specialists, and surgeons can compare their local conditions with our study's benchmarks to make decisions about whether to implement preoperative MRSA testing. Third-party payers may want to consider covering such a strategy. (Am J Manag Care. 2010; 16(7): e163-e173)

AB NRXN1 is highly expressed in brain and has been shown recently to be associated with ASD, schizophrenia, cognitive and behavioral abnormalities, and alcohol and nicotine dependence. We present three families, in whom we identified intragenic rearrangements within NRXN1 using a clinical targeted oligonucleotide array CGH. An similar to 380 kb deletion was identified in a woman with Asperger syndrome, anxiety, and depression and in all four of her children affected with autism, anxiety, developmental delay, and speech delay but not in an unaffected child. An similar to 180 kb tandem duplication was found in a patient with autistic disorder and cognitive delays, and in his mother and younger brother who have speech delay. An similar to 330 kb tandem duplication was identified in a patient with autistic features. As predicted by conceptual translation, all three genomic rearrangements led to the premature truncation of NRXN1. Our data support previous observations that NRXN1 may be pathogenic in a wide variety of psychiatric diseases, including autism spectrum disorder, global developmental delay, anxiety, and depression.

AB Families with early-onset Alzheimer's disease (AD) sharing a single PSEN2 mutation exhibit a wide range of age-at-onset, suggesting that modifier loci segregate within these families. While APOE is known to be an age-at-onset modifier, it does not explain all of this variation. We performed a genome scan within nine such families for loci influencing age-at-onset, while simultaneously controlling for variation in the primary PSEN2 mutation (N141I) and APOE. We found significant evidence of linkage between age-at-onset and chromosome 1q23.3 (P< 0.001) when analysis included all families, and to chromosomes 1q23.3 (P G 0.001), 17p13.2 (P=0.0002), 7q33 (P=0.017), and 11p14.2 (P = 0.017) in a single large pedigree. Simultaneous analysis of these four chromosomes maintained strong evidence of linkage to chromosomes 1q23.3 and 17p13.2 when all families were analyzed, and to chromosomes 1q23.3, 7q33, and 17p13.2 within the same single pedigree. Inclusion of major gene covariates proved essential to detect these linkage signals, as all linkage signals dissipated when PSEN2 and APOE were excluded from the model. The four chromosomal regions with evidence of linkage all coincide with previous linkage signals, associated SNPs, and/or candidate genes identified in independent AD study populations. This study establishes several candidate regions for further analysis and is consistent with an oligogenic model of AD risk and age-at-onset. More generally, this study also demonstrates the value of searching for modifier loci in existing datasets previously used to identify primary causal variants for complex disease traits.

AB Although beta-blockers have been endorsed by guidelines committees for the treatment of patients with hypertension, particularly those with significant CVD and high CVD risk, there are concerns about conventional beta-blockers related to poorer clinical outcomes compared with other classes of antihypertensive agents, as well as deleterious effects on quality of life and lipid and carbohydrate metabolism. beta-Blockers comprise a heterogeneous group of antihypertensive agents, including nonselective agents, cardioselective, nonvasodilating agents, and vasodilating agents that either combine beta-nonselectivity with alpha-blockade or possess cardioselectivity without alpha-blockade. The pharmacologic, mechanistic, and hemodynamic differences between conventional, nonvasodilating beta-blockers and vasodilating beta-blockers are discussed in this review, with a focus on the cardioselective vasodilating beta-blocker nebivolol. These differences may have important clinical implications, particularly in the treatment of complicated hypertension, such as that associated with patients with diabetes or the cardiometabolic syndrome, elderly patients, and African American patients, suggesting that mechanism of action may be an important consideration when choosing a beta-blocker.

AB beta-Blockers have played a key role in the management of hypertension-related cardiovascular disease for decades, and continue to be recommended as a mainstay of therapy in national guidelines statements. Recent data have shown less optimal reductions in total mortality, CVD mortality, and CVD events with beta-blockers compared with renin-angiotensin system-blocking agents or calcium channel blockers. The beta-blocker class, however, spans a wide range of agents, and the growing concern about the risk-benefit profile of beta-blockers should not be generalized to later-generation vasodilating beta-blockers such as carvedilol and nebivolol. A growing database from hypertension studies confirms the clinical efficacy and safety of vasodilating beta-blockers, and outcome studies indicate that these agents can play an important role in global CVD reduction in patients with hypertensive or ischemic heart failure.

AB This report highlights a roundtable discussion that occurred during the annual meeting of the International Diabetes Federation (IDF) in November 2009, in Montreal, Quebec, Canada. Participants included Bernard Zinman, MD, Michael A. Nauck, MD, PhD, Jorge Plutzky, MD, and Allison B. Goldfine, MD. The roundtable was chaired by Vivian A. Fonseca, MD. Among the topics discussed were the burden of type 2 diabetes mellitus and the importance of "appropriate therapy," which includes not only managing glycemia but also the management of concomitant risk factors such as hypertension and dyslipidemia. The discussants also identified issues that remain to be resolved, such as determining the nature of first-line therapy (e. g., should initial dual-agent therapy be encouraged?) and agreeing upon the most appropriate agent to be combined with metformin, which is the current standard of care. Among the new treatments discussed for type 2 diabetes were the analogues of the incretin hormones glucagonlike peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), namely, the GLP-1 receptor agonists-as well as the inhibitors of dipeptidyl peptidase-4 (DPP-4), the enzyme that regulates the bioactivity of the endogenous incretin hormones. These agents have some interesting advantages; not only do they effectively lower glucose, but they also have demonstrated beneficial metabolic and cardiovascular effects. Particularly with respect to the GIP and GLP-1, weight loss, blood pressure reductions, and beta-cell function improvements have been observed in clinical trials. What remains to be determined, by means of additional clinical experience and perhaps additional head-to-head trials, are the long-term benefits of GLP-1 receptor agonists and DPP-4 inhibitors and the sorts of roles these 2 classes of agents may play in the type 2 diabetes therapeutic continuum.

AB Objective: The objective is to present an uncommon case of squamous cell carcinoma (SCC) arising from extensive recurrent respiratory papillomatosis (RRP) involving the upper and lower airway and temporal bone.
Study Design: This is a case report and a review of the literature.
Methods: We describe a case of a 24-year old woman with a history of human papillomavirus (HPV) type 11 since childhood originating in the larynx and trachea, then progressing to involve the distal pulmonary alveoli and right middle ear through the eustachian tube. Papillomatous growth was treated with multiple surgeries including laser cytoreduction of laryngotracheal papillomatosis and radical mastoidectomy, followed by a trial of chemotherapy. Despite this aggressive treatment regimen, papillomatous growth progressed with recurrence in the right eustachian tube, middle ear, and mastoid eventually extending to involve the calvaria and scalp.
Results: The patient underwent a composite resection of involved tissues, including the scalp, auricle, and lateral temporal bone, with reconstruction using a latissimus dorsi free flap. Final pathologic analysis revealed an extensive infiltrative well-differentiated SCC arising from the papilloma. A review of the literature on aggressive respiratory papillomatosis suggests that malignant transformation of juvenile-onset RRP occurs exclusively in cases positive for HPV-11.
Conclusions: We report an unusual case of SCC originating from extensive RRP involving the airway, temporal bone, and scalp and describe the medical and surgical management. Although the incidence of juvenile-onset RRP transformation to SCC is very low, the presence of HPV-11 as a risk factor for malignant transformation of RRP is becoming evident. (C) 2010 Elsevier Inc.

AB There is an urgent need for early diagnosis in medicine, whereupon effective treatments could prevent irreversible tissue damage. Acute anterior chamber inflammation is the most common form of uveitis and a major cause of vision loss. The proximity of the iris vasculature to the light-permeable cornea and its involvement in ocular inflammation make it an ideal target for noninvasive molecular imaging. To accomplish this, carboxylated fluorescent microspheres (MSs) were conjugated with recombinant P-selectin glycoprotein ligand-1 and systemically injected in endotoxin-induced uveitic animals. MS adhesion in the microcirculation of the anterior and posterior chamber was visualized by intravital microscopy and scanning laser ophthalinoscopy. In iritic animals, significantly higher numbers of recombinant P-selectin glycoprotein ligand-1-conjugated MSs adhered to the endothelium (P = 0.03) matching the increase in leukocyte adhesion. Conjugated MSs specifically interacted with firmly adhering leukocytes, allowing quantification of the endogenous immune response. Topical eye drop treatment with dexamethasone (P < 0.01) or cyclosporine A (P < 0.01) significantly lowered MS adhesion in iris vessels. Surprisingly, topical dexamethasone significantly reduced MS interaction in the fundus vessels (P < 0.01), while cyclosporine A did not. In vivo MS accumulation preceded clinical signs of anterior uveitis and leukocyte adhesion in iris vasculature. This work introduces noninvasive subclinical detection of endothelial injury in the iris vasculature, providing a unique opportunity for quantifying vascular injury and immune response in vivo.

AB Histological transformation, a pivotal event in the natural history of cancers including lymphomas, is typically associated with more aggressive clinical behavior. L3055, a B lymphoma cell line of germinal center (GC) origin, is dependent on follicular dendritic cells (FDCs) for survival and proliferation, similar to GC-B cells. However, L3055 cells become less FDC-dependent after prolonged culture, which is analogous to transformation in vivo. Comparison of two L3055 subclones (i.e., the FDC-dependent indolent clone 12 and the FDC-independent aggressive clone 33) by DNA microarray revealed that CD9 was the most differentially expressed gene (P = 0.05). L3055-12 expresses high levels of CD9 while L3055-33 does not. Reduced levels or loss of CD9 expression is also observed in other CD9-positive B lymphoma cell lines. The resultant CD9-negative cells grow faster than CD9-positive cells due to their greater resistance to apoptosis. Furthermore CD9-negative cells are less dependent on FDCs for their survival and growth compared with CD9-positive cells. CD9 down-regulation in B lymphomas appears to be controlled epigenetically, mainly through histone modifications. These findings imply that CD9 is inversely correlated with B lymphoma progression, and CD9 inactivation may play an important role in B lymphoma transformation.

TI Met Activation in Non-Small Cell Lung Cancer Is Associated with de Novo
Resistance to EGFR Inhibitors and the Development of Brain Metastasis

AB Most non-small cell lung cancer (NSCLC) patients harboring activating epidermal growth factor receptor (EGFR) mutations respond to tyrosine kinase inhibitor (TKI) therapy. However, about 30% exhibit primary resistance to EGFR TKI therapy. Here we report that Met protein expression and phosphorylation were associated with primary resistance to EGFR TKI therapy in NSCLC patients harboring EGFR mutations, implicating Met as a de novo mechanism of resistance. In a separate patient cohort, Met expression and phosphorylation were also associated with development of NSCLC brain metastasis and were selectively enriched in brain metastases relative to paired primary lung tumors. A similar metastasis-specific activation of Met occurred in vitro in the isogenous cell lines H2073 and H1993, which are derived from the primary lung tumor and a metastasis respectively, from the same patient. We conclude that Met activation is found in NSCLC before EGFR-targeted therapy and is associated with both primary resistance to EGFR inhibitor therapy and with the development of metastases. If confirmed in larger cohorts, our analysis suggests that patient tumors harboring both Met activation and EGFR mutation could potentially benefit from early intervention with a combination of EGFR and Met inhibitors.

AB Stolzmann KL, Gagnon DR, Brown R, Tun CG, Garshick E: Risk factors for chest illness in chronic spinal cord injury: A prospective study. Am J Phys Med Rehabil 2010; 89: 576-583.
Objective: Chest illnesses commonly cause morbidity in persons with chronic spinal cord injury. Risk factors remain poorly characterized because previous studies have not accounted for factors other than spinal cord injury.
Design: Between 1994 and 2005, 403 participants completed a respiratory questionnaire and underwent spirometry. Participants were contacted at a median of 1.7 yrs [interquartile range: 1.3-2.5 yrs] apart over a mean (SD) of 5.1 +/- 3.0 yrs and asked to report chest illnesses that had resulted in time off work, spent indoors, or in bed since prior contact.
Results: In 97 participants, there were 247 chest illnesses (0.12/person-year) with 54 hospitalizations (22%). Spinal cord injury level, completeness of injury, and duration of injury were not associated with illness risk. Adjusting for age and smoking history, any wheeze (relative risk = 1.92; 95% confidence interval: 1.19, 3.08), pneumonia or bronchitis since spinal cord injury (relative risk = 2.29; 95% confidence interval: 1.40, 3.75), and physician-diagnosed chronic obstructive pulmonary disease (relative risk = 2.17; 95% confidence interval: 1.08, 4.37) were associated with a greater risk of chest illness. Each percent-predicted decrease in forced expiratory volume in 1 sec was associated with a 1.2% increase in risk of chest illness (P = 0.030).
Conclusions: In chronic spinal cord injury, chest illness resulting in time spent away from usual activities was not related to the level or completeness of spinal cord injury but was related to reduced pulmonary function, wheeze, chronic obstructive pulmonary disease, a history of pneumonia and bronchitis, and smoking.

Am J Physiol Endocrinol Metab 299: E110-E116, 2010. First published April 27, 2010; doi:10.1152/ajpendo.00192.2010.-Endothelial progenitor cells (EPCs) play an important role in angiogenesis, which is essential for numerous physiological processes as well as tumor growth. Several microRNAs (miRNAs) have been reported to be involved in angiogenesis. MiR-34a, recently reported as a tumor suppressor, has been found to target silent information regulator 1 (Sirt1), leading to cell cycle arrest or apoptosis. However, the role of miR-34a in EPC-mediated angiogenesis was unknown. The present study tested the hypothesis that miR-34a inhibits EPC-mediated angiogenesis by inducing senescence via suppressing Sirt1. Bone marrow-derived EPCs from adult male Spraque-Dawley rats were used. Results of flow cytometry showed that EPCs after 7 days of culture expressed both stem cell markers CD34 and CD133 and endothelial cell markers VEGFR-2 (flk-1) and VE-cadherin. MiR-34a was expressed in normal EPCs, and overexpression of miR-34a via its mimic transfection significantly increased its expression and impaired in vitro EPC angiogenesis. MiR-34a overexpression led to a significantly increased EPC senescence, paralleled with an similar to 40% Sirt1 reduction. Furthermore, knockdown of Sirt1 by its siRNA resulted in diminished EPC angiogenesis and increased senescence. Finally, overexpression of miR-34a increased the level of Sirt1 effector-acetylated forkhead box O transcription factors 1 (FoxO1), an effect mimicked in EPCs following Sirt1 knockdown. In conclusion, miR-34a impairs EPC-mediated angiogenesis by induction of senescence via inhibiting Sirt1.

AB Beck P, Ihara E, Hirota SA, MacDonald J, Meng D, Nanthakumar N, Podolsky D, Xavier R. Exploring the interplay of barrier function and leukocyte recruitment in intestinal inflammation by targeting fucosyltransferase VII and trefoil factor 3. Am J Physiol Gastrointest Liver Physiol 299: G43-G53, 2010. First published March 18, 2010; doi:10.1152/ajpgi.00228.2009.-Intestinal mucosal integrity is dependent on epithelial function and a regulated immune response to injury. Fucosyltransferase VII (Fuc-TVII) is an essential enzyme required for the expression of the functional ligand for E- and P-selectin. Trefoil factor 3 (TFF3) is involved in both protecting the intestinal epithelium against injury as well as aiding in wound repair following injury. The aim of the present study was to assess the interplay between barrier function and leukocyte recruitment in intestinal inflammation. More specifically, we aimed to examine how targeted disruption of Fuc-TVII either in wild-type or TFF3(-/-) mice would alter their susceptibility to colonic injury. TFF3 and Fuc-TVII double-knockout mice (TFF3/Fuc-TVII(-/-) mice) were generated by mating TFF3(-/-) and Fuc-TVII(-/-) mice. Colitis was induced by administration of dextran sodium sulfate (DSS) (2.5% wt/vol) in the drinking water. Changes in baseline body weight, diarrhea, and fecal blood were assessed daily. Upon euthanasia, extents of colonic inflammation were assessed macroscopically, microscopically, and through quantification of myeloperoxidase (MPO) activity. Colonic lymphocyte subpopulations were assessed at 6 days after administration of DSS by flow cytometry and immunohistochemistry. No baseline intestinal inflammation was found in TFF3/Fuc-TVII(-/-), TFF3(-/-), Fuc-TVII(-/-), or wild-type mice. Loss of Fuc-TVII resulted in a reduction in disease severity whereas TFF3(-/-) mice were markedly more susceptible to DSS-induced colitis. Remarkably, the loss of Fuc-TVII in TFF3(-/-) mice markedly decreased the severity of DSS-induced colitis as evidenced by reduced weight loss, diarrhea, decreased colonic MPO levels and improved survival. Furthermore, the loss of TFF3 resulted in increased severity of spontaneous colitis in IL-2/beta-microglobulin-deficient mice. These studies highlight the importance of the interplay between factors involved in the innate immune response, mucosal barrier function, and genes involved in regulating leukocyte recruitment and other aspects of the immune response.

First published April 30, 2010; doi:10.1152/ajpheart.00906.2009.-We have sought evidence that arachidonic acid (AA) induces mitochondrial depolarization in isolated myocytes by a lipoxygenase (LOX)-dependent mechanism and that such depolarization might contribute to arrhythmogenesis following ischemia-reperfusion injury. A method was developed for measuring mitochondrial depolarization in isolated adult rat myocytes in suspension, using tetramethylrhodamine ethyl ester. The addition of AA to myocytes resulted in mitochondrial depolarization that was inhibited by the LOX inhibitor baicalein, by the reactive oxygen species (ROS) scavenger mercaptoproprionylglycine, and by the anion channel inhibitor diisothiocyanatostilbene-disulfonic acid (DIDS). AA induced mitochondrial uncoupling and mitochondrial ATPase activity in myocytes, but both were insensitive to baicalein. We conclude that the metabolic effect of AA in myocytes puts mitochondria into an energetically compromised state where membrane potential is easily changed by the DIDS-sensitive LOX/ROS-mediated opening of an inner membrane anion channel. In an in vivo anesthetized rat model of coronary artery occlusion, baicalein was found to strongly inhibit arrhythmias induced by ischemia-reperfusion injury. Arrhythmias following ischemia-reperfusion injury have been previously associated with DIDS-sensitive ROS-mediated mitochondrial depolarization, and free fatty acids including AA were previously found to accumulate during such injury. We therefore conclude that arrhythmias following ischemia-reperfusion injury might originate from mitochondrial depolarization mediated by LOX and AA.

Alterations in membrane type-1 matrix metalloproteinase abundance after the induction of thoracic aortic aneurysm in a murine model. Am J Physiol Heart Circ Physiol 299: H114-H124, 2010. First published April 23, 2010; doi:10.1152/ajpheart.00028.2010.-Thoracic aortic aneurysms (TAAs) develop as a result of dysregulated extracellular matrix remodeling mediated by several matrix metalloproteinases (MMPs). Membrane type-1 MMP (MT1-MMP) is the prototypical member of a unique family of membrane-bound MMPs, possessing multiple substrates and functions. The present study tested the hypothesis that MT1-MMP expression, abundance, and activity would be elevated during TAA development and that this protease is produced primarily by mesenchymal cells within the thoracic aorta. Descending thoracic aortas were harvested from C57BL/6J mice at multiple time points (2, 4, 8, and 16 wk, n = 15 each) post-TAA induction (0.5M CaCl(2), 15 min) and compared with reference controls (n = 15). The expression and abundance of MT1-MMP, MMP-2, and tissue inhibitor of metalloproteinase (TIMP)-2 were assessed by quantitative PCR and immunoblot analysis. MT1-MMP activity was determined by fluorescent peptide assay. MT1-MMP was localized within the aortic wall by immunohistochemistry. MT1-MMP abundance and localization in live animals (8 wk post-TAA induction vs. control) was determined by microultrasound imaging with an MT1-MMP-targeted microbubble contrast agent. Aortic diameter was increased 172 +/- 7% at 16 wk post-TAA induction (P < 0.05). MT1-MMP and MMP-2 mRNA levels were elevated at 2 wk post-TAA induction (P < 0.05). MT1-MMP protein abundance increased progressively to a maximum of 178 +/- 26% at 16 wk post-TAA induction, whereas MMP-2 and TIMP-2 peaked at 2 wk post-TAA induction (526 +/- 93% and 376 +/- 48%, respectively, P < 0.05). MT1-MMP colocalized with fibroblasts, and MT1-MMP-targeted contrast binding was elevated in 8-wk TAA-induced mice versus control mice (217 +/- 53% vs. 81 +/- 8%, P < 0.05). In conclusion, these novel results suggest that MT1-MMP plays a dynamic multifunctional role in TAA development and, therefore, may provide a significant target for therapeutic strategies.

Short-term disruption in regional left ventricular electrical conduction patterns increases interstitial matrix metalloproteinase activity. Am J Physiol Heart Circ Physiol 299: H217-H224, 2010. First published May 14, 2010; doi: 10.1152/ajpheart.00065.2010.-Increased matrix metalloproteinase (MMP) abundance occurs with adverse left ventricular (LV) remodeling in a number of cardiac disease states, including those induced by long-standing arrhythmias. However, whether regionally contained aberrant electrical activation of the LV, with consequent dyskinesia, alters interstitial MMP activation remained unknown. Electrical activation of the LV of pigs (n = 10, 30-35 kg) was achieved by pacing (150 beats/min) at left atrial and LV sites such that normal atrioventricular activation (60 min) was followed by regional early LV activation for 60 min within 1.5 cm of the paced site and restoration of normal atrioventricular pacing for 120 min. Regional shortening (piezoelectric crystals) and interstitial MMP activity (microdialysis with MMP fluorogenic substrate) at the LV pacing site and a remote LV site were monitored at 30-min intervals. During aberrant electrical stimulation, interstitial MMP activity at the paced site was increased (122 +/- 4%) compared with the remote region (100%, P < 0.05). Restoration of atrioventricular pacing after the 60-min period of aberrant electrical activation normalized segmental shortening (8.5 +/- 0.4%), but MMP activity remained elevated (121 +/- 6%, P , 0.05). This study demonstrates that despite the restoration of mechanical function, disturbances in electrical conduction, in and of itself, can cause acute increases in regional in vivo MMP activation and, therefore, contribute to myocardial remodeling.

AB Objectives. We assessed the prevalence and predictors of past-year unmet needs for 5 types of health care services in a national sample of homeless adults.
Methods. We analyzed data from 966 adult respondents to the 2003 Health Care for the Homeless User Survey, a sample representing more than 436000 individuals nationally. Using multivariable logistic regression, we determined the independent predictors of each type of unmet need.
Results. Seventy-three percent of the respondents reported at least one unmet health need, including an inability to obtain needed medical or surgical care (32%), prescription medications (36%), mental health care (21%), eyeglasses (41%), and dental care (41%). In multivariable analyses, significant predictors of unmet needs included food insufficiency, out-of-home placement as a minor, vision impairment, and lack of health insurance. Individuals who had been employed in the past year were more likely than those who had not to be uninsured and to have unmet needs for medical care and prescription medications.
Conclusions. This national sample of homeless adults reported substantial unmet needs for multiple types of health care. Expansion of health insurance may improve health care access for homeless adults, but addressing the unique challenges inherent to homelessness will also be required.

AB Rationale The degree to which chronic respiratory health effects caused by exposures to cotton dust and endotoxin is reversible after cessation of textile work is unknown.
Objectives: To investigate changes in lung function and respiratory symptoms after cessation of textile work and to determine whether past exposure to cotton dust and endotoxin or smoking history modify the associations.
Methods: We performed a prospective cohort study consisting of 447 cotton textile workers exposed to cotton dust and 472 unexposed silk textile workers, with a 25-year follow-up. Spirometry testing and respiratory questionnaires were conducted at 5-year intervals. Generalized estimated equations were used to model the average 5-year change in FEV(1) and odds ratios of respiratory symptom prevalence.
Measurements and Main Results: Years since cessation of textile work was positively associated with 11.3 ml/yr and 5.6 ml/yr gains in 5-year FEV(1) change for cotton and silk workers, respectively. Among male cotton workers, smokers gained more FEV(1) per year after cessation of exposure than did nonsmokers, and the risk of symptoms of chronic bronchitis and byssinosis was larger for smoking than for nonsmoking male cotton workers.
Conclusions: Cessation of textile work was significantly associated with improvement in lung function and respiratory symptoms. The positive effect of work cessation was greater for cotton workers than for silk workers. For cotton workers, the improvement in lung function loss after cessation of textile work was greater among smokers, but no differences were observed for silk workers.

AB Rationale Although obstructive sleep apnea is associated with physiological perturbations that increase risk of hypertension and are proatherogenic, it is uncertain whether sleep apnea is associated with increased stroke risk in the general population.
Objectives: To quantify the incidence of ischemic stroke with sleep apnea in a community-based sample of men and women across a wide range of sleep apnea.
Methods: Baseline polysomnography was performed between 1995 and 1998 in a longitudinal cohort study. The primary exposure was the obstructive apnea hypopnea index (OAHI) and outcome was incident ischemic stroke.
Measurements and Main Results: A total of 5,422 participants without a history of stroke at the baseline examination and untreated for sleep apnea were followed for a median of 8.7 years. One hundred ninety-three ischemic strokes were observed. In covariate-adjusted Cox proportional hazard models, a significant positive association between ischemic stroke and OAHI was observed in men (P value for linear trend: P = 0.016). Men in the highest ANI quartile (>19) had an adjusted hazard ratio of 2.86 (95% confidence interval, 1.1-7.4). In the mild to moderate range (OAHI, 5-25), each one-unit increase in AN! in men was estimated to increase stroke risk by 6% (95% confidence interval, 2-10%). In women, stroke was not significantly associated with OAHI quartiles, but increased risk was observed at an OAHI greater than 25.
Conclusions: The strong adjusted association between ischemic stroke and OAHI in community-dwelling men with mild to moderate sleep apnea suggests that this is an appropriate target for future stroke prevention trials.

AB OBJECTIVE. The objective of this study was to evaluate the image quality and diagnostic performance of simulated low-dose MDCT examinations in patients with Crohn's disease.
MATERIALS AND METHODS. Thirty-five MDCT examinations from 25 patients (14 males and 11 females; age range, 16-86 years) with known or suspected Crohn's disease were retrospectively evaluated. The MDCT images (5 mm thickness) were modified by artificially introducing noise using volume CT noise simulation software to simulate low-dose MDCT data acquired with noise indexes (NIs) of 18-35. The 175 MDCT image data sets generated were then randomized and reviewed by two readers to assess the subjective image quality and diagnostic accuracy for confidently detecting Crohn's disease findings on a 5-point scale (1, definitely absent; 5, definitely present). The image quality, diagnostic performance, and radiation dose from the original MDCT examinations served as a reference standard for comparison.
RESULTS. The simulated low-dose CT images with elevated NIs of 18-25 yielded optimal image quality and concordant diagnostic accuracy with standard-dose scans with a mean baseline volume CT dose index of 16 +/- 3.34 (SD) mGy (image quality score, 4-4.9 vs 4.95, respectively; p = 0.4). Images simulating NIs of 30-35 were considered degraded because of excessive image noise and presented lower diagnostic performance (range of image quality score, 3-3.6; weighted. = 0.25-0.37; p < 0.001). Diagnostic performance and reader confidence for the determination of Crohn's disease manifestations in cases in which the reference standard was positive were higher at NIs of = 25 compared with NI of 30 (reader confidence score, 4.5 vs 3.6, respectively; p < 0.05) and an NI of 35 (3.2, p < 0.05). Compared with the standard-dose examination, a 31-64% reduction in radiation dose was estimated for NI levels of 18-25, which corresponds to image noise of 19-27 HU in subcutaneous fat.
CONCLUSION. Processed MDCT images with the introduction of noise to simulate low-dose MDCT examinations with NI levels of 18-25 allows substantial dose reduction for CT examinations in Crohn's disease without compromising diagnostic information.

SO AMERICAN JOURNAL OF ROENTGENOLOGY

AB OBJECTIVE. Electronic medical record (EMR) systems permit integration of contextual nonimaging EMR data into examination interpretation; however, the extra effort required to search and review these nonradiologic data are not well characterized. We assessed the gross frequency and pattern of EMR usage in the interpretation of diagnostic CT and MRI examinations.
SUBJECTS AND METHODS. We defined nonradiologic EMR data as laboratory data, nonimaging specialty report, clinical note, and administrative data not available on PACS. For abdominal, neuroradiologic, and musculoskeletal CT and MRI, we prospectively recorded the time required for image analysis (including prior imaging studies and their reports), nonradiologic EMR use, and initial report drafting by fellows and staff in randomized sessions. We assessed EMR use as a fraction of work activity and according to technique, sub-specialty, inpatient status, and radiologist experience.
RESULTS. We observed 372 CT and MRI interpretations by 33 radiologists. For CT, radiologists used the EMR in 34% of abdominal, 57% of neuroradiologic, and 38% of musculoskeletal interpretations. For MRI, EMR was used in 73% of abdominal, 56% of neuroradiologic, and 33% of musculoskeletal interpretations. For CT, EMR usage comprised 18%, 14%, and 18% of diagnostic effort (image analysis plus EMR use) for abdominal, neuroradiologic, and musculoskeletal interpretations, respectively; for MRI, EMR usage comprised 21%, 16%, and 15% of diagnostic effort for abdominal, neuroradiologic, and musculoskeletal interpretations, respectively. Frequency of EMR use was significantly greater for neuroradiology CT and abdominal MRI (p < 0.05, Fisher's test). EMR usage was not consistently related to inpatient status for CT or radiologist experience.
CONCLUSION. For CT and MRI interpretation, EMR usage is frequent and comprises a significant fraction of diagnostic effort.

AB Background: Anterior cruciate ligament (ACL) deficiency alters 6 degrees of freedom knee kinematics, yet only anterior translation and internal rotation have been the primary measures in previous studies.
Purpose: To compare the 6 degrees of freedom knee kinematics and the graft forces after single- and double-bundle ACL reconstructions under various external loading conditions.
Study Design: Controlled laboratory study.
Methods: Ten human cadaveric knees were tested with a robotic testing system under 4 conditions: intact, ACL deficient, single-bundle reconstructed with a quadrupled hamstring tendon graft, and double-bundle reconstructed with 2 looped hamstring tendon grafts. Knee kinematics and forces of the ACL or ACL graft in each knee were measured under 3 loading conditions: an anterior tibial load of 134 N, a simulated quadriceps muscle load of 400 N, and combined tibial torques (10 N.m valgus and 5 N.m internal tibial torques) at 0 degrees, 15 degrees, 30 degrees, 60 degrees, and 90 degrees of knee flexion.
Results: The double-bundle reconstruction restored the anterior and medial laxities closer to the intact knee than the single-bundle reconstruction. However, the internal rotation of the tibia under the simulated quadriceps muscle load was significantly decreased when compared with the intact knee after both reconstructions, more so after double-bundle reconstruction (P<.05). The entire graft force of the double-bundle reconstruction was more similar to that of the intact ACL than that of the single-bundle reconstruction. However, the posterolateral bundle graft in the double-bundle reconstructed knee was overloaded as compared with the intact posterolateral bundle.
Conclusion: The double-bundle reconstruction can better restore the normal anterior-posterior and medial-lateral laxities than the single-bundle reconstruction can, but an overloading of the posterolateral bundle graft can occur in a double-bundle reconstructed knee.

AB Background: The function of the anteromedial (AM) and posterolateral (PL) bundles of the anterior cruciate ligament (ACL) during gait has not been reported.
Hypothesis: The AM and PL bundles have distinct functional behavior during the stance phase of treadmill gait.
Study Design: Descriptive laboratory study.
Methods: Three-dimensional models of the knee were created by magnetic resonance images from 8 healthy subjects. The contour of the 2 bundle attachments were constructed on each model. Each bundle was represented by a straight line connecting its tibial and femoral attachment centroids. Next, the knee kinematics during the stance phase of gait was determined with a dual fluoroscopic imaging system. The relative elongation, sagittal plane elevation, coronal plane elevation, and transverse plane deviation of the 2 bundles were measured directly from heel strike to toe-off.
Results: At heel strike, the AM and PL bundles had first peak elongation of 9% +/- 7% and 9% +/- 13%, respectively. At 50% progress of the stance phase, both bundles were maximally elongated, 12% +/- 7% for the AM bundle and 13% +/- 15% for the PL bundle. No significant difference was found for each bundle between 40% and 60% of the stance phase (P>.05). With increasing knee flexion, the sagittal plane and coronal plane elevations of the 2 bundles decreased, whereas the deviation angles increased.
Conclusion: Both bundles are anisometric and function in a similar manner during the stance phase of gait. They were maximally elongated throughout the midstance where they were stretched maximally to resist anterior tibial translation.

AB BACKGROUND: Laparoscopic cholecystectomy (LC) accounts for more than 85% of cholecystectomies. Factors prompting open cholecystectomy (OC) or conversion from LC to OC (CONY) are not completely understood.
METHODS: Prospectively collected data from the National Surgical Quality Improvement Program (NSQIP) were combined with administrative data to identify patients undergoing cholecystectomy from October 2005 to October 2008. Three cohorts were defined: LC, OC, and CONV. Using logistic hierarchical modeling, we identified predictors of the choice of OC and the decision to CONV.
RESULTS: A total of 11,669 patients underwent cholecystectomy at 117 VA hospitals, including 9,530 LC (81.7%). While the rate of conversion from LC to OC remained stable over the study period (9.0% overall), the percentage of OC decreased from 11.5% in 2006 to 10.1% in 2007 and 8.9% in 2008 (P = .0002). Compared with LC, the OC cohort had more comorbidities (35 of 41 preoperative characteristics, all P < .05), a higher 30-day. morbidity rate (18.7% vs 4.8%. P < .0001), and a higher 30-day mortality rate (2.4% vs .4%, P < .0001). American Society of Anesthesiologist (ASA) class, patient comorbidities (eg, ascites, bleeding disorders, pneumonia) and functional status predicted a choice of OC. Age, preoperative albumin, previous abdominal surgery and emergency status predicted OC and CONV (all P < .05). A higher hospital conversion rate was independently predictive of OC (odds ratio [1% rate increase]: 1.05 [1.02-1.07]; P = .0004).
CONCLUSION: In the last 3 years, there has been a trend towards performing fewer OCs in VA hospitals. More patient comorbidities and higher hospital-level conversion rates are predictive of the choice to perform or convert to OC. Published by Elsevier Inc.

SPECIMENS; HOT-SPOT; DIAGNOSIS
AB BACKGROUND: Management of patients with thyroid nodules is based on establishing an accurate diagnosis; however, differentiating benign from malignant lesions preoperatively is not always possible using current cytological techniques. Novel molecular testing on cytological material could lead to clearer treatment algorithms. B-Raf(V600E) mutation is the most common genetic alteration in thyroid cancer, specifically found in papillary thyroid cancer (PTC), and usually reported to be associated with aggressive disease.
DATA SOURCE: A literature search using PubMed identified all the pertinent literature on the identification and utilization of the B-Raf(V600E) mutation in thyroid cancer.
CONCLUSIONS: The utility of using B-Raf mutation testing for nodules with indeterminate cytology is limited since many of those nodules (benign and malignant) do not harbor B-Raf mutations. However, when the pathologist sees cytological features suspicious for PTC, B-Raf(V600E) mutation analysis may enhance the assessment of preoperative risks for PTC, directing a more aggressive initial surgical management when appropriate.

AB The clinical application of xenotransplantation poses immunologic, ethical, and microbiologic challenges. Significant progress has been made in the investigation of each of these areas. Among concerns regarding infectious risks for human xenograft recipients is the identification in swine of infectious agents including porcine endogenous retroviruses (PERV) that are capable of replication in some human cell lines. PERV replication has, however, been difficult to demonstrate in primate-derived cell lines and in preclinical studies of non-human primates receiving porcine xenografts. Endogenous 'retroviral restriction factors' are intracellular proteins and components of the innate immune system that act at various steps in retroviral replication. Recent studies suggest that some of these factors may have applications in the management of endogenous retroviruses in xenotransplantation. The risks of PERV infection and the potential role of retroviral restriction factors in xenotransplantation are reviewed in detail.

ID SURGICAL SKILLS; OPERATING-ROOM; PROFICIENCY
AB Virtual reality (VR) simulators may enhance surgical resident colonoscopy skills, but the duration of skill retention and the effects of different simulator training methods are unknown. Medical students participating in a randomized trial of independent (automated simulator feedback only) versus proctored (human expert feedback plus simulator feedback) simulator training performed a standardized VR colonoscopy scenario at baseline, at the end of training (posttraining), and after a median 4.5 months without practice (retention). Performances were scored on a 10-point scale based on expert proficiency criteria and compared for the independent and proctored groups. Thirteen trainees (8 proctored, 5 independent) were included. Performance at retention testing was significantly better than baseline (median score 10 vs 5, P < 0.0001), and no different from posttraining (median score 10 vs 10, P = 0.19). Score changes from baseline to retention and from posttraining to retention were no different for the proctored and independent groups. Overinsufflation and excessive force were the most common reasons for nonproficiency at retention. After proficiency-based VR simulator training, colonoscopy skills are retained for several months, regardless of whether an independent or proctored approach is used. Error avoidance skills may not be retained as well as speed and efficiency skills.

AB BACKGROUND: Current techniques of peripheral nerve block have major limitations, including lack of differentiation between motor and sensory fibers and potential toxicity of local anesthetics. Recent studies have suggested that a nociceptive-selective nerve block can be achieved via a transient receptor potential vanilloid type 1 activator (capsaicin) along with local anesthetics. We hypothesized that the combination of potent transient receptor potential vanilloid type 1 agonist resiniferatoxin (RTX) and selected antidepressants (amitriptyline, doxepin, and fluoxetine, also potent sodium channel blockers) would produce prolonged and predominantly sensory nerve block.
METHODS: Rats were anesthetized with isoflurane, and 0.2 mL of amitriptyline, doxepin, or fluoxetine was deposited next to the surgically exposed sciatic nerves (n = 8 per group). Some animals received a second injection containing RTX (n = 8 per group). The effect of nerve block was assessed by neurobehavioral tests of the motor function (extensor postural thrust) and the nocifensive reaction (mechanical pinch).
RESULTS: A single application of RTX produced nociceptive-selective sciatic nerve block, whereas antidepressants produced nociceptive and motor block. The combined administration of RTX and antidepressant resulted in a predominantly nociceptive nerve block. Compared with antidepressants or RTX alone, the combination prolonged the nociceptive nerve block more than the motor block.
CONCLUSIONS: The combined application of RTX and antidepressants produced a markedly prolonged nociceptive peripheral nerve block in rat sciatic nerves compared with either agent alone. However, the 2-drug regimen also elicited prolonged blockade of the motor function, although disproportionately less compared with the nociceptive modality, suggesting the existence of nontransient receptor potential vanilloid type 1 mediated mechanisms. The mechanisms through which RTX affects nociceptive signal transduction/transmission have yet to be fully elucidated. (Anesth Analg 2010;111:207-13)

AB Background: Data are sparse on epinephrine treatment for stinging insect hypersensitivity (SIH) reactions.
Objective: To establish the frequency of receiving more than 1 dose of epinephrine in patients presenting to the emergency department (ED) with SIH reactions.
Methods: We performed a medical record review of all 153 patients with SIH reactions presenting to 3 EDs in Boston, Massachusetts, between January 1, 2001, and December 31, 2006. Patients were identified by International Classification of Diseases, Ninth Revision (ICD-9) codes (989.5, 995.0, and 995.3). We focused on clinical presentations and treatments, including epinephrine treatments given before and during the ED visit.
Results: The cohort was 54% male, with a median age of 33 years. Bees were the most frequently reported triggering insect (74%). A total of 59% of patients experienced large local reactions, whereas 36% had systemic reactions (10% cutaneous systemic and 26% anaphylaxis). The remaining 5% presented with normal local reactions to insect stings. Among patients with systemic reactions, 82% were stung within 3 hours of arrival at the ED. Most (60%) received treatments before arrival at the ED, including 26% who received epinephrine. While in the ED, these patients received antihistamines (76%), systemic corticosteroids (55%), and epinephrine (9%). Overall, 35% of patients with systemic reactions received epinephrine, and among this subset, 16% received more than 1 dose. Most patients with systemic reactions (67%) were discharged to home. At ED discharge, 68% received a prescription for self-injectable epinephrine, but only 11% had documentation of referral to an allergist.
Conclusions: Among patients with systemic SIH reactions who received epinephrine, 16% received a second dose. Physicians should consider prescribing 2 doses of self-injectable epinephrine for patients at risk for systemic SIH reactions. Ann Allergy Asthma Immunol. 2010; 105: 85-93.

AB The genomic revolution in medicine has not escaped attention of clinicians and scientists involved in medical management and research studies of immune thrombocytopenic purpura (ITP). In principle, ITP biology and care will benefit greatly from modern methods to understand the patterns of gene expression and genetic markers associated with fundamental parameters of the disease including predictors of remission, risk factors for severity, determinants of response to various therapies, and possibly biological sub-types. However, applying modern genetics to ITP carries severe challenges: (a) Achieving adequate sample sizes is a fundamental problem because ITP is rare (and in pediatric ITP, chronic cases constitute only about one fourth of the total); (b) familial transmission of childhood ITP is so rare that a convincing pedigree requires consideration of other immunologic or hematologic disorders; (iii) ITP is probably biologically heterogeneous, based on clinical observations, immunological studies, and animal models. Here we review the advantages and disadvantages of potential genetic approaches. Sufficient information is available to set reasonable bounds on which genetic analyses of ITP are feasible and how they are most likely to be accomplished. The highest priority is for accurate phenotypes to compare to genetic analyses. Several registries worldwide hold promise for accomplishing this goal.

TI Thalamic Sensitization Transforms Localized Pain into Widespread

AB Objective: Focal somatic pain can evolve into widespread hypersensitivity to nonpainful and painful skin stimuli (allodynia and hyperalgesia, respectively). We hypothesized that transformation of headache into whole-body allodynia/hyperalgesia during a migraine attack is mediated by sensitization of thalamic neurons that process converging sensory impulses from the cranial meninges and extracephalic skin.
Methods: Extracephalic allodynia was assessed using single unit recording of thalamic trigeminovascular neurons in rats and contrast analysis of blood oxygenation level-dependent (BOLD) signals registered in functional magnetic resonance imaging (fMRI) scans of patients exhibiting extracephalic allodynia.
Results: Sensory neurons in the rat posterior thalamus that were activated and sensitized by chemical stimulation of the cranial dura exhibited long-lasting hyperexcitability to innocuous (brush, pressure) and noxious (pinch, heat) stimulation of the paws. Innocuous, extracephalic skin stimuli that did not produce neuronal firing at baseline (eg, brush) became as effective as noxious stimuli (eg, pinch) in eliciting large bouts of neuronal firing after sensitization was established. In migraine patients, fMRI assessment of BOLD signals showed that brush and heat stimulation at the skin of the dorsum of the hand produced larger BOLD responses in the posterior thalamus of subjects undergoing a migraine attack with extracephalic allodynia than the corresponding responses registered when the same patients were free of migraine and allodynia.
Interpretation: We propose that the spreading of multimodal allodynia and hyperalgesia beyond the locus of migraine headache is mediated by sensitized thalamic neurons that process nociceptive information from the cranial meninges together with sensory information from the skin of the scalp, face, body, and limbs.

AB Three clustered, homologous paraoxonase genes (PON1, PON2, and PON3) have roles in preventing lipid oxidation and detoxifying organophosphates. Recent reports describe a genetic association between the PON genes and sporadic amyotrophic lateral sclerosis (ALS). We now report that in genomic DNA from individuals with familial and sporadic ALS, we have identified at least 7 PON gene mutations that are predicted to alter PON function.

AB Objective: Anemia and operative blood loss are common in the elderly, but evidence is lacking on whether intraoperative blood transfusions can reduce the risk of postoperative death.
Methods: We analyzed retrospective data from 239,286 patients 65 years of older who underwent major noncardiac surgery in 1997 to 2004 at veteran hospitals nationwide. Propensity-score matching was used to adjust for differences between patients who received intraoperative blood transfusions (9.4%) and those who did not, and data were used to determine the association between intraoperative blood transfusion and 30-day postoperative mortality.
Results: After propensity-score matching, intraoperative blood transfusion was associated with mortality risk reductions in patients with preoperative hematocrit levels of <24% (odds ratio: 0.60, 95% CI: 0.41-0.87), and in patients with hematocrit of 30% or greater when there is substantial (500999 mL) blood loss (odds ratio: 0.35, 95% CI: 0.22-0.56 for hematocrit levels between 30%-35.9% and 0.78, 95% CI: 0.62-0.97 for hematocrit levels of 36% or greater). When operative blood loss was <500 mL, transfusion was not associated with mortality reductions for patients with hematocrit levels of 24% or greater, and conferred increased mortality risks in patients with preoperative hematocrit levels between 30% to 35.9% (odds ratio 1.29, 95% CI: 1.04-1.60).
Conclusions: Intraoperative blood transfusion is associated with a lower 30- day postoperative mortality among elderly patients undergoing major noncardiac surgery if there is substantial operative blood loss or low preoperative hematocrit levels (<24%). Transfusion is associated with increased mortality risks for those with preoperative hematocrit levels between 30% and 35.9% and <500 mL of blood loss.

AB Objective: In this randomized, controlled, unblinded trial, we sought to test Repeat Back's (RB) effect on comprehension following informed consent discussions.
Summary Background Data: RB has been suggested as a method to improve patient comprehension when obtaining informed consent. In this technique, patients are asked to recount what they have been told in the informed consent discussion. Despite preliminary data, this practice has not been evaluated in any large scale study.
Methods: This study was conducted in 7 Veterans Health Administration Medical Centers where informed consent is obtained using iMedConsent, the VA's computer based platform. Patients scheduled for elective surgeries were randomized to RB (a module added to the iMedConsent package) or standard iMedConsent (no RB). Comprehension was tested after the informed consent using procedure-specific questionnaires. Time stamps in the iMedConsent program estimated the time spent completing the informed consent process. Provider and patient satisfaction were measured using 5-point Likert scales. Statistical comparisons of groups were performed using t-tests and chi(2) tests.
Results: A total of 575 patients were enrolled. In the RB group, providers spent 2.6 minutes longer (P < 0.0001) obtaining informed consent. The mean comprehension score was significantly higher in the RB group (71.4%) versus the no RB group (68.2%, P = 0.03); the effect was greatest in carotid endarterectomy patients (RB = 73.4% vs. no RB = 67.7%, P = 0.02). Quality of decision making was rated similarly. Providers were neutral to slightly favorable regarding RB.
Conclusions: RB implemented within an electronic informed consent system improved patient comprehension. The additional time required was acceptable to providers. RB should be considered as an enhancement to surgical informed consent.

WOUND-INFECTION; PATIENT SAFETY; OF-CARE; SURGERY; DATABASES; OUTCOMES
AB Background: Hospitals increasingly rely on surgical quality assessment programs that require considerable resources to capture outcomes after hospital discharge. However, it is unclear whether capturing postdischarge complications and deaths is important. Our objectives were (1) to determine the frequency of postdischarge complications and deaths and (2) to determine whether hospital rankings change with inclusion of postdischarge outcomes.
Methods: From 181 hospitals participating in the American College of Surgeon's National Surgical Quality Improvement Program, 329,951 patients were identified (2006-2007). Mortality and 19 complications within 30 days of the index operation were categorized as occurring before or after discharge. Risk-adjusted hospital rankings were compared based on whether only predischarge (inpatient) versus both pre- and postdischarge (inpatient and outpatient within 30 days of operation) morbidity and mortality were included.
Results: Postdischarge complications accounted for 32.9% of all complications. Certain complications occurred frequently after discharge: surgical site infections (66.0%), urinary tract infections (39.4%), pulmonary embolisms (42.2%), and deep venous thromboses (34.5%). Of all patients experiencing complications, 39.7% had only postdischarge complications. Of 5827 postoperative deaths, 23.6% occurred after discharge. Hospital quality rankings changed when postdischarge outcomes were excluded versus included for morbidity (median hospital rank change: 16 ranks; interquartile range, 7-36) and mortality (median hospital rank change: 14 ranks; interquartile range, 6-29), and there was disagreement in outlier status designations depending on whether postdischarge events were included (morbidity: kappa = 0.546; mortality: kappa = 0.507).
Conclusions: A substantial proportion of postoperative complications and deaths occur after hospital discharge. Inclusion of postdischarge events considerably affects hospital quality rankings and outlier status designations. Quality improvement programs and research that do not consider postdischarge outcomes may offer incomplete information to hospitals, payers, providers, and patients.

We sought to evaluate the predictive value of breast magnetic resonance imaging (MRI) in detecting axillary lymph node metastases prior to initiation of neoadjuvant chemotherapy (NAC) and in detecting residual lymph node metastases after NAC in women found to be node positive prior to NAC.
Women underwent breast MRI with axillary evaluation prior to initiation of NAC and again after completion of NAC. Pathologic confirmation of lymph node status was confirmed by sentinel lymph node biopsy (SLNB), image-guided axillary fine-needle aspiration (FNA)/core biopsy, or axillary lymph node dissection. We evaluated the sensitivity, specificity, and negative and positive predictive values of MRI in detecting axillary node involvement.
Seventy-four women completed NAC and underwent surgery. Sensitivity of MRI in detecting axillary node involvement prior to NAC was 64.7% and specificity was 100%, with positive and negative predictive values of MRI of 100% and 77.8%, respectively. Sensitivity and specificity of MRI to identify residual pathologic axillary lymph node disease following NAC were 85.7% and 89%, respectively, while the positive and negative predictive values were 92% and 80.9%, respectively.
Breast MRI has moderate sensitivity and high specificity for predicting axillary lymph node status prior to NAC. In patients found to be node positive prior to NAC, MRI was able to predict with moderate sensitivity and specificity whether residual nodal disease was present. The accuracy of MRI is not adequate to obviate either the need for staging by sentinel node biopsy or the need for completion axillary dissection in women determined to be node positive prior to NAC.

AB Invasive lobular breast cancer (ILC) is less common than invasive ductal breast cancer (IDC), more difficult to detect mammographically, and usually diagnosed at a later stage. Does delayed diagnosis of ILC affect survival? We used a national registry to compare outcomes of patients with stage-matched ILC and IDC.
Query of the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) tumor registry identified 263,408 women diagnosed with IDC or ILC between 1993 and 2003. Survival of patients matched by T and N stage was compared using Kaplan-Meier curves and log-rank analysis.
When compared with IDC, ILC was more likely to be > 2 cm (43.1 vs. 32.6%; P < 0.001), lymph node positive (36.8 vs. 34.4%; P < 0.001), and ER positive (93.1 vs. 75.6%; P < 0.001). The 5-year disease-specific survival (DSS) was significantly better for patients with ILC than for those with IDC, before (90 vs. 88%; P < 0.001) and after matching for stage T1N0 (98 vs. 96%; P < 0.001), T2N0 (94 vs. 88%; P < 0.001), and T3N0 (92 vs. 83%, P < 0.001). The 5-year DSS for patients with nodal metastasis of ILC vs. IDC was 89% vs. 88% (P = NS) for stage T1N1, 81 vs. 73% (P < 0.001) for T2N1, and 72 vs. 56% (P < 0.001) for T3N1. Multivariate analysis identified a 14% survival benefit for ILC (hazard ratio 0.86, 95% confidence interval 0.80-0.92).
Stage-matched prognosis is better for patients with ILC than for those with IDC. Our findings support a different biology for ILC and are important for counseling and risk stratification.

AB Objective To examine associations of anti-cyclic citrullinated peptide (aCCP) antibody and rheumatoid factor (RF) concentrations with future disease activity in men with rheumatoid arthritis (RA).
Methods Outcome measures were examined in male US veterans with RA and included (1) proportion of observations in remission (disease activity score (DAS28) <= 2.6); (2) remission for >= 3 consecutive months; and (3) area under the curve (AUC) for DAS28. The associations of autoantibody concentration (per 100 unit increments) with outcomes were examined using multivariate regression.
Results 826 men with RA were included in the analysis; the mean (SD) age was 65 (10.5) years and follow-up was for 2.6 (1.3) years. Most were aCCP (75%) and RF (80%) positive. After multivariate adjustment, aCCP (OR 0.93; 95% CI 0.89 to 0.96) and RF concentrations (OR 0.92; 95% CI 0.90 to 0.94) were associated with a lower odds of remission, a lower proportion of observation in remission (p=0.017 and p=0.002, respectively) and greater AUC DAS28 (p=0.092 and p=0.007, respectively). Among patients with discordant autoantibody status, higher concentrations of both aCCP and RF trended towards an inverse association with remission (OR 0.93; 95% CI 0.83 to 1.05 and OR 0.80; 95% CI 0.59 to 1.10, respectively).
Conclusions Higher aCCP concentrations (particularly in RF-positive patients) are associated with increased disease activity in US veterans with RA, indicating that aCCP concentration is predictive of future disease outcomes in men.

AB Background: Peripheral arterial disease (PAD) is a common disorder with multiple options for treatment, ranging from medical interventions, surgical revascularization, and endovascular therapy. Despite the explosive advances in endovascular therapy, cost-effective methods of care have not been well defined. We analyze therapeutic strategies, outcomes, and medical cost of treatment among Medicare patients with PAD.
Methods and Results: Patients who underwent therapy for PAD were identified from a 5% random sample of Medicare beneficiaries from Medicare Standard Analytic Files for the period 1999-2005. Clinical outcomes (death, amputation, new clinical symptoms related to PAD) and direct medical costs were examined by chosen revascularization options (endovascular, surgical, and combinations). One-year PAD prevalence increased steadily from 8.2% in 1999 to 9.5% in 2005. The risk-adjusted time to first post-treatment clinical outcome was lowest in those treated with "percutaneous transluminal angioplasty (PTA) or atherectomy and stents" (HR, 0.829; 95% CI, 0.793-0.865; p < 0.001) and stents only (HR, 0.904; 95% CI, 0.848-0.963; p = 0.002) compared with PTA alone. The lowest per patient risk-adjusted costs during the quarter of the first observed treatment were associated with "PTA and stents" ($15,197), and stents only ($15,867). Risk-adjusted costs for surgical procedures (bypass and endarterectomy) were $27,021 during the same period. Diabetes was present in 61.7% of the PAD population and was associated with higher risks of clinical events and higher medical costs compared with PAD patients without diabetes.
Conclusion: The clinical and economic burden of PAD in the Medicare population is substantial, and the interventions used to treat PAD are associated with differences in clinical and economic outcomes. Prospective cost-effectiveness analyses should be included in future PAD therapy trials to inform payers and providers of the relative value of available treatment options.

AB Background: The natural history of coronary artery disease (CAD) after vascular surgery is poorly defined. The aim of this study was to determine the temporal change of coronary artery lesions requiring revascularization with a percutaneous coronary intervention (PCI) after elective vascular surgery and to determine the utility of preoperative biomarkers on predicting those patients at risk for new coronary lesions.
Methods: The Coronary Artery Revascularization Prophylaxis Trial tested the long-term survival benefit of coronary artery revascularization before elective vascular surgery. Among randomized patients who subsequently required PCI after surgery, the stenosis of the culprit lesion from the follow-up angiogram was compared with the preoperative vessel stenosis at the identical site on the baseline angiogram.
Results: A total of 30 patients underwent PCI for progressive symptoms at a median of 11.5 (interquartiles: 4.5-18.5) months postsurgery. Of 30 patients, 16 (53%) had nonobstructive CAD preoperatively (group 1) with a stenosis that increased from 17 +/- 6% to 91 +/- 2% (P < 0.01) and 14 (47%) had severe CAD at the culprit site preoperatively (group 2), with a stenosis that increased 89 +/- 2% (P = 0.15). The only biomarker that was an identifier of early coronary artery lesion formation in group 1 compared with group 2 patients was a higher baseline homocysteine level (14.6 +/- 1.4 vs. 10.6 +/- 0.7 mg/dL; P = 0.02).
Conclusions: Culprit coronary artery lesions requiring PCI after an elective vascular operation often arise from in-stent restenosis. Therapies that either stabilize existing plaques or prevent restenosis, particularly among patients with elevated homocysteine levels, have the greatest promise for improving postoperative outcomes.

TI Bilateral Asymptomatic Extracranial Carotid Artery Aneurysms
SO ANNALS OF VASCULAR SURGERY
LA English
DT Article
ID SURGICAL-TREATMENT; EXPERIENCE; MANAGEMENT; REPAIR
AB Aneurysms of the extracranial carotid arteries are rare and account for 0.4-1% of all arterial aneurysms and about 4% of all peripheral arterial aneurysms. Causes include atherosclerosis, fibromuscular dysplasia, trauma (penetrating and blunt cervical trauma and hyperextension of the neck), iatrogenic lesions, infection, congenital defects, and irradiation arteritis. Atherosclerosis is responsible for 46-70% of all carotid artery aneurysms. The most frequent site of carotid artery aneurysms is the common carotid artery, particularly at its bifurcation and proximal internal carotid artery (ICA). The middle and distal portions of the ICA are the next most common sites. Aneurysms at the point of bifurcation are usually fusiform, whereas those located in the middle and distal portions of the ICA are usually saccular. This uncommon but interesting vascular disorder usually presents as a parapharyngeal pulsatile mass. It can be partially or completely thrombosed and thereby cause embolization or compression of neurovascular structures, with ruptures and ischemic events as other complications. Surgical treatment of extracranial carotid aneurysms is required in most cases, to avert disastrous consequences. Conservative management of extracranial ICA aneurysms has resulted in a mortality rate of nearly 71%. Nonoperative treatment is generally indicated in young patients who have nonpenetrating traumatic and spontaneously dissecting aneurysms. However, when anticoagulation therapy fails or when persistent neurologic symptoms or progressive expansion of the aneurysm occurs, surgical repair is indicated.

AB Aim: To evaluate circulating endothelial lineage cells (ELCs) as biomarkers of tumor neovascularization in patients with pancreatic ductal adenocarcinoma (PDAC). Materials and Methods: ELCs were isolated from the peripheral blood of patients with PDAC (n=14) or controls (n=17) before and after tumor resection/surgery and quantified using flow cytometry. Vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) were detected in tumor using immunohistochemistry and in plasma using an ELISA technique. Results: Circulating ELC levels were increased in patients with PDAC compared to controls. After PDAC resection, ELC levels declined. ELC level increases were associated with cancer recurrence. VEGF and PlGF were identified in cancer cells and exocrine pancreas cells. Only PlGF was detected in tumor-associated inflammatory cells. Plasma levels of PlGF were higher in patients with PDAC compared to controls. Conclusion: Circulating ELCs are a potential biomarker of PDAC neovascularization, and PlGF may be an important target in treatment of PDAC.

AB The central role of reactive oxygen species (ROS) in osteoclast differentiation and in bone homeostasis prompted us to characterize the redox regulatory system of osteoclasts. In this report, we describe the expression and functional characterization of PAMM, a CXXC motif-containing peroxiredoxin 2-like protein expressed in bone marrow monocytes on stimulation with M-CSF and RANKL. Expression of wild-type (but not C to G mutants of the CXXC domain) PAMM in HEK293 cells results in an increased GSH/GSSG ratio, indicating a shift toward a more reduced environment. Expression of PAMM in RAW264.7 monocytes protected cells from hydrogen peroxide-induced oxidative stress, indicating that PAMM regulates cellular redox status. RANKL stimulation of RAW 264.7 cells caused a decrease in the GSH/GSSG ratio (reflecting a complementary increase in ROS). In addition, RANKL-induced osteoclast formation requires phosphorylation and translocation of NF-kappa B and c-Jun. In stably transfected RAW 264.7 cells, PAMM overexpression prevented the reduction of GSH/GSSG induced by RANKL. Concurrently, PAMM expression completely abolished RANKL-induced p100 NF-kappa B and c-Jun activation, as well as osteoclast formation. We conclude that PAMM is a redox regulatory protein that modulates osteoclast differentiation in vitro. PAMM expression may affect bone resorption in vivo and help to maintain bone mass. Antioxid.

AB This article identifies novel factors involved in cholesterol reduction by probiotic bacteria, which were identified using genetic and proteomic approaches. Approximately 600 Lactobacillus acidophilus A4 mutants were created by random mutagenesis. The cholesterol-reducing ability of each mutant was determined and verified using two different methods: the o-phthalaldehyde assay and gas chromatographic analysis (GC). Among screened mutants, strain BA9 showed a dramatically diminished ability to reduce cholesterol, as demonstrated by a 7.7% reduction rate, while the parent strain had a more than 50% reduction rate. The transposon insertion site was mapped using inverse PCR (I-PCR), and it was determined using bioinformatic methods that the deleted region contained the Streptococcus thermophilus catabolite control protein A gene (ccpA). In addition, we have shown using two-dimensional gel electrophoresis (2-DE) that several proteins, including a transcription regulator, FMN-binding protein, major facilitator superfamily permease, glycogen phosphorylase, the YknV protein, and fructose/tagatose bisphosphate aldolase, were strongly regulated by the ccpA gene. In addition, in vivo experiments investigating ccpA function were conducted with rats. Rats fed wild-type L. acidophilus A4 showed a greater than 20% reduction in total serum cholesterol, but rats fed BA9 mutant L. acidophilus showed only an approximately 10% reduction in cholesterol. These results provide important insights into the mechanism by which these lactic acid bacteria reduce cholesterol.

AB Objectives: (1) To determine the prevalence of interstitial lung disease (ILD) and isolated low diffusing capacity for carbon monoxide (DLCO) in a large cohort of outpatients with dermatomyositis. (2) To compare the pulmonary abnormalities of patients with classic dermatomyositis and those with skin-predominant dermatomyositis.
Design: Retrospective cohort study.
Setting: University hospital outpatient dermatology referral center.
Patients: Medical records of 91 outpatients with adult-onset dermatomyositis seen between May 26, 2006, and May 25, 2009, were reviewed.
Main Outcome Measures: Presence of ILD on thin-slice chest computed tomographic (CT) scans and DLCO.
Results: Of the 71 patients with dermatomyositis who had CT or DLCO data, 16 of 17 (23%; 95% confidence interval [CI], 13%-33%) had ILD as defined by CT results. All patients with ILD had a reduced DLCO, and the ILD prevalence was not different between patients with skin-predominant dermatomyositis (10 of 35 [29%]) and those with classic dermatomyositis (6 of 36 [17%]) (P=.27). Eighteen of 71 patients with dermatomyositis (25%; 95% CI, 15%-36%) (7 of 35 [20%] with skin-predominant dermatomyositis; 11 of 36 [31%] with classic dermatomyositis; P=.41) had a low DLCO in the absence of CT findings showing ILD. The prevalence of malignant disease was higher in patients with classic dermatomyositis than in those with skin-predominant dermatomyositis (P=.02), and no patients with skin-predominant dermatomyositis had internal malignant disease.
Conclusions: Radiologic ILD and isolated DLCO reductions, which may signify early ILD or pulmonary hypertension, are common in dermatology outpatients with both classic and skin-predominant dermatomyositis. Because DLCO testing is both inexpensive and sensitive for pulmonary disease, it may be appropriate to screen all patients with dermatomyositis with serial DLCO measurements and base further testing on DLCO results.

AB Background: Dermatomyositis is an autoimmune disease of unknown etiology characterized by inflammation of the skin and muscles. Several medications have been implicated in the development of dermatomyositis; however, the disease has rarely been linked to the use of tumor necrosis factor (TNF) inhibitors. We report 4 cases of dermatomyositis that developed or were exacerbated by exposure to the TNF inhibitors etanercept and adalimumab.
Observation: Four patients with symptoms of inflammatory arthritis were treated with TNF inhibitors for a duration ranging from 2 months to 2 years. All 4 patients developed symptoms consistent with dermatomyositis, including inflammatory rash and muscle weakness. Their symptoms persisted after discontinuation of the treatment with the TNF inhibitors but responded to treatment with corticosteroids and immunosuppressive medications.
Conclusions: Tumor necrosis factor inhibitors have been associated with the onset of a number of autoimmune disorders, most commonly vasculitis and a lupuslike syndrome. Rarely have they been associated with dermatomyositis. The 4 cases reported herein indicate that TNF inhibitor use can be associated with either induction or exacerbation of dermatomyositis.

AB Objective: To determine the effect of desiccating stress on corneal angiogenic responses in dry eye disease (DED) using a murine model.
Methods: Dry eye was induced in murine eyes using high-flow desiccated air. Corneas were double stained with CD31 (panendothelial marker) and LYVE-1 (lymphatic endothelial marker). Real-time polymerase chain reaction was performed to quantify expression of vascular endothelial growth factors (VEGF-A, VEGF-C, and VEGF-D) and their receptors (VEGFR-2 and VEGFR-3) in the cornea on days 6, 10, and 14. Enumeration of CD11b(+)/LYVE-1(+) monocytic cells was performed in corneas with DED on clay 14. Flow cytometric evaluation of the draining lymph nodes in normal mice and mice with DED was performed to determine whether DED is associated with homing of mature (major histocompatibility complex class II(hi)) antigen-presenting cells to the lymphoid compartment.
Results: Lymphatic vessels unaccompanied by blood vessels were seen growing toward the center of corneas with DED. Significant increases in lymphatic area (P<.001) and lymphatic caliber (P<.02) were seen on day 14 of disease. Lymphangiogenic-specific VEGF-D and VEGFR-3 levels increased earliest on day 6 followed by increased VEGF-C, VEGF-A, and VEGFR-2 levels. Increased recruitment of CD11b(+)/LYVE-1(+) monocytic cells to the cornea and homing of mature CD11b(+) antigen-presenting cells to the draining lymph nodes were also associated with DED.
Conclusion: Low-grade inflammation associated with DED is an inducer of lymphangiogenesis without accompanying hemangiogenesis.

TI Economic Evaluation of Toric Intraocular Lens A Short- and Long-term
Decision Analytic Model
SO ARCHIVES OF OPHTHALMOLOGY
LA English
DT Article
ID CATARACT-SURGERY; ASTIGMATISM CORRECTION; COST-UTILITY
AB Objective: To assess the economic value of improved uncorrected visual acuity among patients with cataract and preexisting astigmatism treated with toric intraocular lenses (IOLs) compared with conventional monofocal IOLs.
Methods: We developed a decision analytic model of hypothetical patients with preexisting astigmatism. We examined costs and outcomes among patients 65 years and older with cataract and preexisting astigmatism (1.5-3.0 diopters) who were receiving either toric or conventional IOLs with and without intraoperative refractive correction (IRC). Data were obtained from the literature and from a survey of 60 US ophthalmologists. Total medical costs of bilateral treatment were calculated for the first posttreatment year and remaining lifetime. Cost-effectiveness and cost-utility outcomes were computed. Future costs and utilities were discounted by 3%.
Results: A larger proportion of patients receiving toric IOLs achieved distance vision spectacle independence (67%) and uncorrected visual acuity of 20/25 or better OU (53%) compared with conventional IOLs with (63% and 48%, respectively) or without IRC (53% and 44%, respectively), resulting in fewer future vision corrections. Toric IOLs provided an additional 10.20 quality-adjusted life years (QALYs) compared with conventional IOLs with (10.14 QALYs) and without IRC (10.10 QALYs). Higher first-year costs of the toric IOL ($5739) compared with the conventional IOL with ($5635) or without ($4687) IRC were offset by lifetime cost savings of $34 per patient, $393 per patient achieving uncorrected visual acuity of 20/25 or better, and $349 per QALY compared with the conventional IOL without IRC.
Conclusions: Toric IOLs reduce lifetime economic costs by reducing the need for glasses or contact lenses following cataract removal. These results can inform physicians and patients regarding the value of toric IOLs in the treatment of cataract and preexisting astigmatism.

TI Survival in Patients With Presymptomatic Diagnosis of Metastatic Uveal
Melanoma
SO ARCHIVES OF OPHTHALMOLOGY
LA English
DT Article
ID LIVER METASTASES
AB Objective: To determine if patients diagnosed as having metastatic uveal melanoma before the onset of symptoms experience more favorable survival outcomes than patients diagnosed after the onset of symptoms.
Methods: A retrospective cohort study was performed among 90 patients who were diagnosed as having metastatic uveal melanoma after proton beam irradiation by routine surveillance testing (asymptomatic group) compared with 259 patients who were diagnosed as having metastatic uveal melanoma after development of symptoms (symptomatic group). The median survival times and cumulative rates of melanoma-related death after diagnosis of metastasis were compared between the 2 groups.
Results: No differences were noted between groups in known prognostic factors for melanoma-related death, including age and tumor size. Cumulative rates of melanoma-related death were higher for patients in the symptomatic group vs the asymptomatic group (P<.001, log-rank test) owing to differences in mortality observed in the first year after diagnosis of metastasis (87.8% vs 68.5%). By the second year after diagnosis of metastasis, cumulative rates had reached 90% or higher in both groups. The median time to melanoma-related death after primary tumor diagnosis was 40.6 months in the asymptomatic group vs 45.1 months in the symptomatic group (P=.61).
Conclusion: Presymptomatic detection of metastatic uveal melanoma by routine surveillance testing seems to confer a survival advantage only in the first year after diagnosis of metastasis, which is likely because of lead-time bias.

Intervention: Posterior pharyngeal wall augmentation with injectable CaHA. Main Outcome Measure: Nasalence scores recorded as number of standard deviations (SDs) from normalized scores, and perceptual scoring recorded as standardized weighted score and caretaker satisfaction from direct report.
Results: Twelve children who had undergone injection pharyngoplasty with CaHA were identified. Of the 12 children, 8 demonstrated success at 3 months as defined by nasalence (<1 SD above normal nasalance scores), perceptual scoring (decrease in weighted score), and overall caretaker satisfaction. Four children were followed up for more than 24 months and continued to demonstrate stable success. The 4 children who failed the procedure all failed before the 3-month evaluation and demonstrated increased baseline severity of VPI as defined by increased preoperative nasalence scores (5.25 SD vs 2.4 SD above normalized scores), perceptual scores (weighted score, 4.25 vs 3.85), and characteristic nasendoscopy findings of a broad-based velopharyngeal gap or unilateral adynamism. Three of the 4 treatment failures occurred early in the senior author's (C.J.H.) experience with the technique.
Conclusions: Injection pharyngoplasty with CaHA is a useful adjunct in the treatment of children with mild VPI. Efficacy and safety have been demonstrated more than 24 months after injection. Patient selection and operative technique are critical to the success of the procedure. Success is seen most often in children with mild VPI and small well-defined velopharyngeal gaps consistent with touch closure.

AB Context.-Whole-slide images (WSI) are a tool for remote interpretation, archiving, and teaching. Ovarian frozen sections (FS) are common and hence determination of the operating characteristics of the interpretation of these specimens using WSI is important.
Objectives.-To test the reproducibility and accuracy of ovarian FS interpretation using WSI, as compared with routine analog interpretation, to understand the technology limits and uniq
