AB Purpose: To quantify interfractional anatomical variations and their dosimetric impact during the course of fractionated proton therapy (PT) of prostate cancer and to assess the robustness of the current treatment planning techniques.
Methods: Simulation and daily in-room CT scans from ten prostate carcinoma patients were analyzed. PT treatment plans (78 Gy in 39 fractions of 2 Gy) were created on the simulation CT, delivering 25 fractions to PTV1 (expanded from prostate and seminal vesicles), followed by 14 boost fractions to PTV2 (expanded from prostate). Plans were subsequently applied to daily CT, with beams aligned to the prostate center in the sagittal plane. For five patients having a sufficiently large daily imaging volume, structure contours were manually drawn, and plans were evaluated for all CT sets. For the other five patients, the plans were evaluated for six selected fractions. The daily CT was matched to the simulation CT through deformable registration. The registration accuracy was validated for each fraction, and the three patients with a large number of accurately registered fractions were used for dose accumulation.
Results: In individual fractions, the coverage of the prostate, seminal vesicles, and PTV1 was generally maintained at the corresponding prescription dose. For PTV2, the volume covered by the fractional prescription dose of 2 Gy (i.e., V2) was, on average, reduced by less than 3% compared to the simulation plan. Among the 225 (39 x 5 + 6 x 5) fractions examined, 15 showed a V2 reduction larger than 5%, of which ten were caused by a large variation in rectal gas, and five were due to a prostate shift in the craniocaudal direction. The fractional dose to the anterior rectal wall was found to increase for one patient who had large rectal gas volume in 25 of the 39 fractions, and another who experienced significant prostate volume reduction during the treatment. The fractional bladder dose generally increased with decreasing fullness. In the total accumulated dose for the three patients after excluding a few fractions with inaccurate registration due to a large amount of rectal gas (a condition inconsistent with RTOG protocol), 98.5%, 96.6%, and 98.2% of the PTV2 received the prescription dose of 78 Gy. The V75 and V70 of the anterior rectal wall and bladder both remained within tolerance.
Conclusions: The results confirm that the PT planning techniques and dose constraints used at our institution ensure that target coverage to the prescription dose is maintained in the presence of interfractional anatomical variations. Dose coverage in individual fractions can be compromised, and normal tissue dose increased, due to deviations in the bladder and rectal volume compared to the simulation plans or progressive changes in the prostate volume during the treatment. Deviations from the plan can be reduced with efforts aimed at maintaining consistent daily patient anatomy. (C) 2011 American Association of Physicists in Medicine. [DOI: 10.1118/1.3604152]

AB microRNAs (miRNA, miR) play an important role in cancer cell growth andmigration; however, the potential roles of miRNAs in osteosarcoma remain largely uncharacterized. By applying a miRNA microarray platform and unsupervised hierarchical clustering analysis, we found that several miRNAs have altered expression levels in osteosarcoma cell lines and tumor tissues when compared with normal human osteoblasts. Three miRNAs, miR-199a-3p, miR-127-3p, and miR-376c, were significantly decreased in osteosarcoma cell lines, whereas miR-151-3p and miR-191 were increased in osteosarcoma cell lines in comparison with osteoblasts. Transfection of precursor miR-199a-3p into osteosarcoma cell lines significantly decreased cell growth and migration, thus indicating that the inhibition effect is associated with an increase in the G(1)-phase and a decrease of the S-phase cell population. In addition, we observed decreased mTOR and Stat3 expression in miR-199a-3p transfected cells. This study provides new insights for miRNAs in osteosarcoma and suggests that miR-199a-3p may play a functional role in osteosarcoma cell growth and proliferation. Restoring miR-199a-3p's function may provide therapeutic benefits in osteosarcoma. Mol Cancer Ther; 10(8); 1337-45. (C) 2011 AACR.

AB We tested the use of the small-molecule Inhibitor of Apoptosis Protein (IAP) inhibitor LBW242 in combination with the standard-of-care therapies of irradiation and temozolomide for malignant gliomas. In vitro assays demonstrated that LBW242 enhanced the cytotoxic activity of radiotherapy, and clonogenic assays showed that the combination therapy led to a synergistic anti-glioma effect in multiple cell lines. Neurosphere assays revealed that the combination of radiation and LBW242 led to a pro-apoptotic effect in these glioma-initiating cell-enriched assays, with a corresponding inhibition of primary tumor cell growth. Athymic mice bearing established human malignant glioma tumor xenografts treated with LBW242 plus radiation and temozolomide demonstrated a synergistic suppression of tumor growth. Taken together, these experiments show that the pro-apoptotic and anti-glioma effects of radiotherapy and chemotherapy can be enhanced by the addition of a small-molecule IAP inhibitor. These results are readily translatable to clinical trial and offer the potential for improved treatment outcomes for patients with glioma.

AB Background: Lowering cholesterol is associated with reduced CNS amyloid deposition and increased dietary cholesterol increases amyloid accumulation in animal studies. Epidemiologic data suggest that use of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) may decrease the risk of Alzheimer disease (AD) and a single-site trial suggested possible benefit in cognition with statin treatment in AD, supporting the hypothesis that statin therapy is useful in the treatment of AD.
Objective: To determine if the lipid-lowering agent simvastatin slows the progression of symptoms in AD.
Methods: This randomized, double-blind, placebo-controlled trial of simvastatin was conducted in individuals with mild to moderate AD and normal lipid levels. Participants were randomly assigned to receive simvastatin, 20 mg/day, for 6 weeks then 40 mg per day for the remainder of 18 months or identical placebo. The primary outcome was the rate of change in the Alzheimer's Disease Assessment Scale-cognitive portion (ADAS-Cog). Secondary outcomes measured clinical global change, cognition, function, and behavior.
Results: A total of 406 individuals were randomized: 204 to simvastatin and 202 to placebo. Simvastatin lowered lipid levels but had no effect on change in ADAS-Cog score or the secondary outcome measures. There was no evidence of increased adverse events with simvastatin treatment.
Conclusion: Simvastatin had no benefit on the progression of symptoms in individuals with mild to moderate AD despite significant lowering of cholesterol.
Classification of evidence: This study provides Class I evidence that simvastatin 40 mg/day does not slow decline on the ADAS-Cog. Neurology (R) 2011;77:556-563

AB Neuropeptides, such as calcitonin gene-related peptide (CGRP), substance P and vasoactive intestinal polypeptide (VIP) are considered important mediators in primary headaches. Increased concentrations of CGRP have been found in jugular venous plasma during attacks of migraine and, concomitant with VIP elevation, during cluster headache. Substance P and CGRP are produced from subsets of trigeminal afferents whereas VIP derives from parasympathetic efferents. Release of these neuropeptides in the meninges causes arterial vasodilatation, mast cell degranulation and plasma extravasation in animal experiments. Particularly CGRP seems to be important, as receptor antagonists have recently been shown to have a therapeutic effect on migraine. Animal models have confirmed the role of CGRP in meningeal nociception. The activity of spinal trigeminal neurons is a sensitive integrative measure of trigeminal activity and CGRP released from central terminals of trigeminal afferents in the spinal trigeminal nucleus has been shown to facilitate nociceptive transmission, most likely by a presynaptic action. The proposed CGRP functions are supported by the distribution of CGRP receptor components localized in the rat cranial dura mater, the trigeminal ganglion and the spinal trigeminal nucleus. The currently available data indicate multiple sites of CGRP action in trigeminal nociception and the pathogenesis of migraine but central CGRP receptors are probably the essential targets in the treatment of migraine using CGRP receptor antagonists.

AB Centrioles are microtubule-derived structures that are essential for the formation of centrosomes, cilia and flagella. The centrosome is the major microtubule organiser in animal cells, participating in a variety of processes, from cell polarisation to cell division, whereas cilia and flagella contribute to several mechanisms in eukaryotic cells, from motility to sensing. Although it was suggested more than a century ago that these microtubule-derived structures are involved in human disease, the molecular bases of this association have only recently been discovered. Surprisingly, there is very little overlap between the genes affected in the different diseases, suggesting that there are tissue-specific requirements for these microtubule-derived structures. Knowledge of these requirements and disease mechanisms has opened new avenues for therapeutical strategies. Here, we give an overview of recent developments in this field, focusing on cancer, diseases of brain development and ciliopathies.

AB OBJECTIVES To describe the number of urethral dilations, urethrotomies, and urethroplasties performed on men with a diagnosis of urethral stricture disease seeking care in the Veterans Affairs (VA) health care system in southern California and southern Nevada over a 5-year period. To date, few health services research studies have evaluated patterns of care for urethral stricture disease using national datasets.
METHODS We analyzed stricture treatment for male veterans with an ICD-9 diagnosis code for urethral stricture in the National Patient Care Database (NPCD). Encounters for urethral stricture procedures performed were identified based on the presence of Physicians Current Procedural Terminology Coding System (4th edition, CPT-4) codes for treatments performed during the fiscal years 2002-2006.
RESULTS A total of 1457 men carried a diagnosis of urethral stricture disease during the index time period. Of these, 333 men (23%) underwent 431 procedures. Of the 216 men who underwent urethral dilations, 170 (79%) underwent only 1 procedure and 26 (12%) underwent 2 procedures. Of the 79 men who underwent urethrotomy, 76 (96%) underwent 1 procedure. Sixteen men (5%) underwent a urethroplasty, 8 of whom underwent a perineal urethrostomy.
CONCLUSIONS The vast majority of men treated for stricture disease underwent only 1 such procedure over a 5-year time period. Further research is required to investigate whether this is a quality-of-care issue or patients refusing intervention. It is possible that some patients may be temporized for a significant period with dilation/urethrotomy, whereas those with rapid recurrence require early urethroplasty. UROLOGY 78: 454-458, 2011.

AB Prospective data regarding risk factors for peripheral artery disease (PAD) are sparse, especially among women; the relative contribution of systolic versus diastolic blood pressure control for incident PAD has not been well studied. We evaluated the association of self-reported blood pressure control with incident symptomatic PAD in middle-aged and older women. We examined the relationship between reported hypertension and incident confirmed symptomatic PAD (n = 178) in 39,260 female health professionals aged = 45 years without known vascular disease at baseline. Median follow-up was 13.3 years. Women were grouped according to presence of reported isolated diastolic (IDH), isolated systolic (ISH), or combined systolic-diastolic hypertension (SDH) using cut-points of 90 and 140 mmHg for diastolic and systolic blood pressure, respectively. SBP and DBP were modeled as continuous and categorical exposures. Multivariable-adjusted hazard ratios (HRs), including adjustment for cardiovascular risk factors, were derived from Cox proportional hazards models. Adjusted HRs compared to women without reported hypertension were 1.0 (0.4-2.8) for IDH, 2.0 (1.3-3.1) for ISH, and 2.8 (1.8-4.5) for SDH. There was a 43% increased adjusted risk per 10 mmHg of reported SBP (95% CI 27-62%) and a gradient in risk according to SBP category (< 120, 120-139, 140-159, and >= 160 mmHg); HRs were 1.0, 2.3, 4.3, and 6.6 (p-trend < 0.001), respectively. Reported DBP, while individually predictive in models excluding SBP, was not predictive after adjustment for SBP. In conclusion, these prospective data suggest a strong prognostic role for uncontrolled blood pressure and, particularly, uncontrolled systolic blood pressure in the development of peripheral atherosclerosis in women.

AB We aimed to determine the relationships between resting left ventricular (LV) wall motion abnormalities (WMAs), aortic plaque, and peripheral artery disease (PAD) in a community cohort. A total of 1726 Framingham Heart Study Offspring Cohort participants (806 males, 65 +/- 9 years) underwent cardiovascular magnetic resonance with quantification of aortic plaque volume and assessment of regional left ventricular systolic function. Claudication, lower extremity revascularization, and ankle-brachial index (ABI) were recorded at the most contemporaneous examination visit. WMAs were associated with greater aortic plaque burden, decreased ABI, and claudication in age-and sex-adjusted analyses (all p < 0.001), which were not significant after adjustment for cardiovascular risk factors. In age-and sex-adjusted analyses, both the presence (p < 0.001) and volume of aortic plaque were associated with decreased ABI (p < 0.001). After multivariable adjustment, an ABI <= 0.9 or prior revascularization was associated with a threefold odds of aortic plaque (p = 0.0083). Plaque volume significantly increased with decreasing ABI in multivariable-adjusted analyses (p < 0.0001). In this free-living population, associations of WMAs with aortic plaque burden and clinical measures of PAD were attenuated after adjustment for coronary heart disease risk factors. Aortic plaque volume and ABI remained strongly negatively correlated after multivariable adjustment. Our findings suggest that the association between coronary heart disease and non-coronary atherosclerosis is explained by cardiovascular risk factors. Aortic atherosclerosis and PAD remain strongly associated after multivariable adjustment, suggesting shared mechanisms beyond those captured by traditional risk factors.

AB Purpose: To prospectively investigate the technical feasibility and performance of image fusion for whole-body diffusion-weighted imaging (wbDWI) and computed tomography (CT) to detect metastases using hybrid positron emission tomography/computed tomography (PET/CT) as reference standard.
Material and Methods: Fifty-two patients (60 +/- 14 years; 18 women) with different malignant tumor disease examined by PET/CT for clinical reasons consented to undergo additional wbDWI at 1.5 Tesla. WbDWI was performed using a diffusion-weighted single-shot echoplanar imaging during free breathing. Images at b = 0 s/mm(2) and b = 700 s/mm(2) were acquired and apparent diffusion coefficient (ADC) maps were generated. Image fusion of wbDWI and CT (from PET/CT scan) was performed yielding for wbDWI/CT fused image data. One radiologist rated the success of image fusion and diagnostic image quality. The presence or absence of metastases on wbDWI/CT fused images was evaluated together with the separate wbDWI and CT images by two different, independent radiologists blinded to results from PET/CT. Detection rate and positive predictive values for diagnosing metastases was calculated. PET/CT examinations mere used as reference standard.
Results: PET/CT identified 305 malignant lesions in 39 of 52 (75%) patients. WbDWI/CT image fusion was technically successful and yielded diagnostic image quality in 73% and 92% of patients, respectively. Interobserver agreement for the evaluation of wbDWI/CT images was kappa = 0.78. WbDWI/CT identified 270 metastases in 43 of 52 (83%) patients. Overall detection rate and positive predictive value of wbDWI/CT was 89% (95% CI, 0.85-0.92) and 94% (95% CI, 0.92-0.97), respectively.
Conclusion: WbDWI/CT image fusion is technically feasible in a clinical setting and allows the diagnostic assessment of metastatic tumor disease detecting nine of 10 lesions as compared with PET/CT.

AB Objective: A major focus of early intervention research is determining the risk of conversion to psychosis and developing optimal algorithms of prediction. Although reported rates of nonconversion vary in the literature, the nonconversion rate always encompasses a majority (50%-85%) of the sample participants. Less is known about the outcome among this group, referred to as false positive individuals.
Method: A longitudinal study was conducted of more than 300 prospectively identified treatment-seeking individuals meeting criteria for a psychosis-risk syndrome. Participants were recruited and evaluated across eight clinical research centers as part of the North American Prodrome Longitudinal Study. Over a 2.5-year follow-up assessment period, 214 (71%) participants had not made the transition to psychosis.
Results: The sample examined included 111 individuals who had at least 1 year of follow-up data available and did not transition to psychosis within the study duration. In year 1, there was significant improvement in ratings for attenuated positive and negative symptoms. However, at least one attenuated positive symptom was still present for 43% of the sample at 1 year and for 41% at 2 years. At the follow-up timepoints, social and role functioning were significantly poorer in the clinical sample relative to nonpsychiatric comparison subjects.
Conclusions: Help-seeking individuals who meet prodromal criteria appear to represent those who are truly at risk for psychosis and are showing the first signs of illness, those who remit in terms of the symptoms used to index clinical high-risk status, and those who continue to have attenuated positive symptoms.

TI Cognitive Effects of Atypical Antipsychotic Medications in Patients With
Alzheimer's Disease: Outcomes From CATIE-AD
SO AMERICAN JOURNAL OF PSYCHIATRY
LA English
DT Article
ID RATING-SCALE BPRS; DEMENTIA; SCHIZOPHRENIA; TRIAL; METAANALYSIS;
OLANZAPINE; QUETIAPINE; SYMPTOMS; DRUGS; RISPERIDONE
AB Objective: The impact of the atypical antipsychotics olanzapine, quetiapine, and risperidone on cognition in patients with Alzheimer's disease is unclear. The authors assessed the effects of time and treatment on neuropsychological functioning during the Clinical Antipsychotic Trials of Intervention Effectiveness-Alzheimer's Disease study (CATIE-AD).
Method: CATIE-AD included 421 outpatients with Alzheimer's disease and psychosis or agitated/aggressive behavior who were randomly assigned to receive masked, flexible-dose olanzapine, quetiapine, risperidone, or placebo. Based on their clinicians' judgment, patients could discontinue the originally assigned medication and receive another randomly assigned medication. Patients were followed for 36 weeks, and cognitive assessments were obtained at baseline and at 12, 24, and 36 weeks. Outcomes were compared for 357 patients for whom data were available for at least one cognitive measure at baseline and one follow-up assessment that took place after they had been on their prescribed medication or placebo for at least 2 weeks.
Results: Overall, patients showed steady, significant declines over time in most cognitive areas, including in scores on the Mini-Mental State Examination (MMSE; -2.4 points over 36 weeks) and the cognitive subscale of the Alzheimer's Disease Assessment Scale (-4.4 points). Cognitive function declined more in patients receiving antipsychotics than in those given placebo on multiple cognitive measures, including the MMSE, the cognitive subscale of the Brief Psychiatric Rating Scale, and a cognitive summary score summarizing change on 18 cognitive tests.
Conclusions: In CATIE-AD, atypical antipsychotics were associated with worsening cognitive function at a magnitude consistent with 1 year's deterioration compared with placebo. Further cognitive impairment is an additional risk of treatment with atypical antipsychotics that should be considered when treating patients with Alzheimer's disease.

AB OBJECTIVE. The purpose of this study was to evaluate initial experience with (18)F-FDG PET/CT after pulmonary radiofrequency ablation of stage IA non-small cell lung cancer to determine whether treatment success or residual disease can be predicted with early postablation PET. SUBJECTS AND
METHODS. Thirty patients with medically inoperable stage IA non-small cell lung cancer (12 men, 18 women; median age, 76 years; range, 60-87 years) underwent outpatient CT-guided radiofrequency ablation over a 33-month period. Mean tumor size was 2.0 cm (range, 1.3-2.9 cm). PET/CT was performed within 60 days before radiofrequency ablation (RFA), within 4 days after RFA, and 6 months after RFA. Metabolic response was categorized as complete response or partial or no response at early post-RFA PET/CT and complete response, partial response, or progressive metabolic disease at 6-month post-RFA PET/CT and was compared with the 1-year clinical event rate (death, disease progression at contrast-enhanced CT, or repeat ablation).
RESULTS. Early PET/CT images, obtained within 4 days of RFA, were evaluable for 26 patients (23 at 6 months). Patients with a complete metabolic response at early PET/CT had a 1-year event rate of 43%, whereas those with partial or no response or disease progression had a 1-year event rate of 67% (p = 0.27). Patients with a complete metabolic response at 6-month PET/CT had a 1-year event rate of 0%. Those with a partial response and those with disease progression had an overall event rate of 75% (p = 0.001).
CONCLUSION. Early post-RFA PET/CT is not necessary and 6-month post-RFA PET/CT findings correlate better with clinical outcome at 1 year.

ID PHASE HELICAL CT; HEPATOCELLULAR-CARCINOMA; REDUCTION FILTERS; CONTRAST
MATERIAL; ABDOMEN
AB OBJECTIVE. The purpose of this study was to determine the upper limit of noise for detection of small low-contrast lesions in a liver phantom.
MATERIALS AND METHODS. A CT liver phantom containing 21 low-contrast, low-attenuation, circular simulated lesions ranging in size from 2.4 to 10 mm was scanned 23 times at different tube current ranges (varying noise index) on a 64-MDCT scanner with automatic tube current modulation. The attenuation of the simulated lesions was 20 HU less than that of the liver-equivalent background. Three radiologists independently reviewed the resultant CT images, which contained either a low-contrast lesion or no lesion and scored certainty of lesion detection using a 4-point Likert scale. Overall performance was evaluated by sensitivity analysis with receiver operator curve and area under the curve (A(z)) computation for ranges of noise index.
RESULTS. The reviewers achieved 100% sensitivity with a noise index of 15 or less for lesions measuring 6.3-10.0 mm (A(z) = 0.96). Increasing noise index to the 17-21 range resulted in a minor decrease in sensitivity and overall performance (sensitivity, 92.3%; A(z) = 0.93). A further increase in noise index to the 23-27 range resulted in a moderate decrease in sensitivity (sensitivity, 81.4%; A(z) = 0.77). Beyond the noise index 23-27 range, sensitivity dropped markedly from 81.4% to 39%. Agreement between the three readers in assessing the image sets was moderate.
CONCLUSION. For detection of small low-contrast lesions in the liver phantom model used in this study, the upper limit of noise index may be in the 15-21 range for sensitivity greater than 90%.

AB Purpose: To present a primarily conceptual introduction to item response theory (IRT) and Rasch models for speech-language pathologists (SLPs).
Method: This tutorial introduces SLPs to basic concepts and terminology related to IRT as well as the most common IRT models. The article then continues with an overview of how instruments are developed using IRT and some basic principles of adaptive testing.
Conclusion: IRT is a set of statistical methods that are increasingly used for developing instruments in speech-language pathology. While IRT is not new, its application in speech-language pathology to date has been relatively limited in scope. Several new IRT-based instruments are currently emerging. IRT differs from traditional methods for test development, typically referred to as classical test theory (CTT), in several theoretical and practical ways. Administration, scoring, and interpretation of IRT instruments are different from methods used for most traditional CTT instruments. SLPs will need to understand the basic concepts of IRT instruments to use these tools in their clinical and research work. This article provides an introduction to IRT concepts drawing on examples from speech-language pathology.

AB BACKGROUND: Arterial blood pressure (BP) measurement at least every 5 minutes is part of the American Society of Anesthesiologists' monitoring standard, but prolonged BP gaps in electronic anesthesia records have been noted. We undertook multicenter studies to determine the frequency of cases with at least 1 interval >= 10 minutes between successive BP measurements and then to ascertain whether educational feedback via an electronic, near real-time notification system alerting providers to the presence of such gaps would reduce their incidence.
METHODS: We evaluated 212,706 electronic anesthesia records from 3 large academic centers. We determined the fraction of cases with >= 10-minute BP monitoring gaps at baseline and did a root cause analysis to determine common causes for these lapses. We then designed and implemented automated systems at 2 of the hospitals to notify point-of-care providers immediately after such 10-minute gaps occurred and determined the subsequent impact of this feedback on BP gap incidence, compared with baseline.
RESULTS: At Hospital A, the notification system reduced the incidence of cases with at least 1 BP gap (1.48% +/- 0.19% SD vs 0.79% +/- 0.36% SD, P < 0.0001). At Hospital B, the gap incidence was not significantly altered when notification was provided after a 10-minute gap had already occurred (2.72% +/- 0.60% SD vs 2.45% +/- 0.48% SD, P = 0.27), but the incidence was reduced when such notification was provided after 6 minutes without a BP reading (2.72% +/- 0.60% SD vs 1.54% +/- 0.19% SD, P < 0.0001). At Hospital C, where notification was not implemented, the baseline rate of BP gaps was consistent across the preintervention and follow-up periods (7.03% +/- 1.27% SD vs 7.13% +/- 0.11% SD, P = 0.74). Although monitors disconnected during position change was the most common identifiable cause of BP gaps, reasons for the missing BP measurements were often not documented. During a week when the electronic charting system was temporarily inoperable, no BP gaps were noted on a convenience sample of 500 paper records from Hospital A (99% upper confidence limit = 0.83%).
CONCLUSIONS: BP gaps of >= 10 minutes were common in electronic anesthesia records, and their incidence was reduced but not eliminated by near real-time feedback to providers. The American Society of Anesthesiologists' standard for BP documentation every 5 minutes might not be achievable with current practices and technology. Anesthesia information management systems users need to be cognizant of the potential for gaps in BP measurement, take steps to minimize their occurrence, and document an explanation when such failures occur.

AB In 2005, the National Institutes of Health sponsored a Consensus Development Project on Criteria for Clinical Trials in chronic graft-versus-host (cGVHD) to achieve consensus about key elements of cGVHD research, including definitions for diagnosis, severity scoring, and response measures. To test these proposed definitions, a multicenter prospective cohort study of people with cGVHD is ongoing. This study will evaluate the performance of proposed prognostic factors, measures of disease activity, and surrogate endpoints for therapeutic response. Data are collected at 6-month intervals in a heterogeneous population of patients reflecting modern transplant techniques and posttransplantation clinical management (target enrollment 672 with cGVHD from I 0 transplantation centers). This report describes the rationale, design, and methods of the cGVHD cohort study, and invites other investigators to collaborate with the Consortium to analyze data or specimens.

AB As success of reduced-intensity conditioning (RIC) hematopoietic stem cell transplantation (HSCT) relies primarily on graft-versus-leukemia (GVL) activity, increased minor HLA disparity in unrelated compared to related donors could have a significant impact on transplant outcomes. To assess whether use of unrelated donors (URD) engenders more potent GVL in RIC HSCT compared to matched related donors (MRD), we retrospectively studied 433 consecutive T-replete 6/6 HLA matched URD (n = 246) and MRD (n = 187) RIC HSCT for hematologic malignancies at our institution. Diseases included: acute myelogenous leukemia (AML) (127), non-Hodgkin lymphoma (NHL) (71), chronic lymphocytic leukemia (CLL) (68), myelodysplastic syndrome (MDS) (64), Hodgkin disease (HD) (40), chronic myeloid leukemia (CML) (25), multiple myeloma (MM) (23), myeloproliferative disorder (MPD) (12), acute lymphoblastic leukemia (ALL) (7), and other leukemia (1). All received uniform fludarabine and intravenous busulfan conditioning, and GVHD prophylaxis with tacrolimus/mini-methroxate (mini-MTX) or tacrolimus/sirolimus +/- mini-MTX. Unrelated donors were younger compared to MRD (median donor age: 33 years versus 52 years, P <.0001), and provided larger CD34(+) products (median CD34(+) cells infused: 8.7 x 10(6)/kg versus 7.5 x 10(6)/kg, P = .002). Distribution of diseases, disease risk, prior transplant, and cytomegalovirus (CMV) status was similar in both cohorts. Cumulative incidence of grade II-IV acute GVHD (at day +180), 2-year chronic GVHD, and 2-year nonrelapse mortality (NRM) were 20% versus 16%, 55% versus 50%, and 8% versus 6% in URD and MRD, respectively (P = NS). Cumulative incidence of relapse at 2 years was lower in URD, 52% versus 65% (P = .005). With median follow-up of 26.5 and 35.8 months, 2-year progression-free survival (PFS) was significantly better in unrelated donor transplants, 39.5% for URD, and 29% for MRD (P = .01). Overall survival (OS) at 2 years were 56% for URD versus 50% for MRD (P = .53). In multivariable analysis, URD was associated with a lower risk of relapse (hazard ratio [FIR] 0.67, P = .002) and superior PFS (HR 0.69, P = .002). These results suggest that URD is associated with greater GVL activity than MRD, and could have practice changing impact on future donor selection in RIC HSCT.

AB BACKGROUND: Bortezomib, an inhibitor of the 26S proteasome and NF-kappa B, may have antitumor activity in adenoid cystic carcinoma (ACC). Preclinical studies have shown synergy between bortezomib and doxorubicin. METHODS: Eligibility criteria included incurable ACC, any number of prior therapies but without an anthracycline, unidimensionally measurable disease, Eastern Cooperative Oncology Group performance status 0-2, and ejection fraction within normal limits. Patients with stable disease for >= 9 months were excluded. Patients received bortezomib 1.3 mg/m(2) by intravenous (IV) push on Days 1, 4, 8, and 11, every 21 days until progression. Doxorubicin 20 mg/m(2) IV on Days 1 and 8 was added at the time of progression. RESULTS: Twenty-five patients were enrolled, of whom 24 were eligible; the most common distant metastatic sites were the lung (n = 22) and the liver (n = 7). There was no objective response with single-agent bortezomib; best response was stable disease in 15 (71%) of 21 evaluable patients. The median progression-free survival and overall survival were 6.4 months and 21 months, respectively. Of 10 evaluable patients who received bortezomib plus doxorubicin, 1 had a partial response, and 6 had stable disease. The most frequent toxicity with bortezomib was grade 3 sensory neuropathy (16%). With bortezomib plus doxorubicin, serious toxicities seen more than once were grade 3-4 neutropenia (n = 3) and grade 3 anorexia (n = 2). CONCLUSIONS: Bortezomib was well tolerated and resulted in disease stabilization in a high percentage of patients but no objective responses. The combination of bortezomib and doxorubicin was also well tolerated and may warrant further investigation in ACC. Cancer 2011;117:3374-82. (C) 2011 American Cancer Society

AB BACKGROUND: Minority patients receive more aggressive care at the end of life, but it is unclear whether this trend is consistent with their preferences. We compared the willingness to use personal financial resources to extend life among white, black, Hispanic, and Asian cancer patients. METHODS: Patients with newly diagnosed lung or colorectal cancer participating in the Cancer Care Outcomes Research and Surveillance observational study were interviewed about myriad aspects of their care, including their willingness to expend personal financial resources to prolong life. We evaluated the association of race/ethnicity with preference for life-extending treatment controlling for clinical, sociodemographic, and psychosocial factors using logistic regression. RESULTS: Among patients (N = 4214), 80% of blacks reported a willingness to spend all resources to extend life, versus 54% of whites, 69% of Hispanics, and 72% of Asians (P<.001). In multivariate analyses, blacks were more likely to opt for expending all financial resources to extend life than whites (odds ratio, 2.41; 95% confidence interval, 1.84-3.17; P < .001). CONCLUSIONS: Black cancer patients are more willing to exhaust personal financial resources to extend life. Delivering quality cancer care requires an understanding of how these preferences impact cancer care and outcomes. Cancer 2011;117:3476-84. (C) 2011 American Cancer Society.

AB Cancer-testis antigens (CTAs) are often specifically expressed in cancer cells and under normal conditions are only considered to be expressed in the germ line cells and the placenta. CTAs are potential targets for cancer immunotherapy and therefore necessitates their expression profiling. The expression profile of LAGE1, MAGE-A4 and NY-ESO1, their possible correlations and interaction, and the clinicopathological associations of each marker were studied. RNA was extracted from fresh esophagectomy tissues of 41 esophageal squamous cell carcinoma (ESCC) patients prior to any other therapeutic intervention. The relative mRNA expression of LAGE1, MAGE-A4 and NY-ESO1 was assessed with the real-time reverse transcription-polymerase chain reaction (RT-PCR) 5' nuclease assay. The overexpression of LAGE1, MAGE-A4 and NY-ESO1 was found in 39, 90.2 and 41.4% of ESCC samples respectively. Of the patients, 97.5% showed an overexpression of at least one CTA. The relative expression of MAGE-A4 was directly associated with lymph node metastasis and the stage of the tumor (p < 0.05). A significant direct correlation was also detected between the MAGE-A4/LAGE1 and MAGE-A4/NY-ESO1 levels of gene expression. MAGE-A4 is identified as a specific biomarker of ESCC with a possible oncogenic role contributing to tumor progression. Interactions between MAGE-A4, LAGE1 and NY-ESO1 and their significant clinical consequences introduce these CTAs as appropriate targets for a polyvalent cancer vaccine.

AB Inner cell mass (ICM) cells of a blastocyst, the source of embryonic stem (ES) cells, are characterized by their unique ability to give rise to all cell types in adult organisms. The epigenomes of germ cells and developing zygotes undergo extensive reprogramming to acquire such a pluripotent state. A major reprogramming event during early embryonic development is the erasure and subsequent re-establishment of patterns of methylation at the 5-position of cytosine (5mC). The recent demonstration that Ten-eleven translocation family proteins, Tet1-3 have the capacity to convert 5mC to 5-hydroxymethylcytosine (5hmC) raises the possibility that 5hmC may act as an distinct epigenetic state contributing to dynamic changes in DNA methylation and transcriptional regulation during embryonic development. In ES cells, Tet1 is highly expressed and 5hmC is present at relatively high levels compared to most differentiated cells, but the functional significance of Tet1 and 5hmC in these pluripotent cells are not clear. Recently, a flurry of papers that profile the distribution of Tet1 and/or 5hmC across the genome of mouse ES cells provide new insights into the role of Tet proteins and 5hmC in regulating expression of genes related to pluripotency and cellular differentiation. Through integrative analyses of datasets from different groups, we reveal the common Tet1 and 5hmC targets in undifferentiated mouse ES cells, which suggest that Tet1 may play a key role in orchestrating the balance between pluripotent and lineage committed states.

AB Brain tumors are heterogeneous tumors composed of differentiated tumor cells that resemble various neural cells and a small number of multipotent cancer stem cells. These tumors modify normal cells in their environment to promote tumor growth, invasion and metastases by various ways. Recent publications show that glioblastoma cells release microvesicles that contain a select subset of cellular proteins and RNAs. These microvesicles are avidly taken up by normal cells in cell culture and can change the translational profile of these cells through delivery of tumor-derived mRNAs, which are translated into functional proteins. In addition to mRNA and proteins, microvesicles have been shown to contain microRNAs, non-coding RNAs and DNA. This commentary explores the recent advances in this novel intercellular communication route and discusses the potential physiological role of microvesicles in brain tumorigenesis.

AB Children bear a large component of the global burden of cholera. Despite this, little is known about immune responses to cholera in children, especially those under 5 years of age. Cholera vaccine studies have demonstrated lower long-term protective efficacy in young children than in older children and adults. Memory B cell (MBC) responses may correlate with duration of protection following infection and vaccination. Here we report a comparison of immune responses in young children (3 to 5 years of age; n = 17), older children (6 to 17 years of age; n = 17), and adults (18 to 60 years of age; n = 68) hospitalized with cholera in Dhaka, Bangladesh. We found that young children had lower baseline vibriocidal antibody titers and higher fold increases in titer between day 2 and day 7 than adults. Young children had higher baseline IgG plasma antibody levels to Vibrio cholerae antigens, although the magnitudes of responses at days 7 and 30 were similar across age groups. As a surrogate marker for mucosal immune responses, we assessed day 7 antibody-secreting cell (ASC) responses. These were comparable across age groups, although there was a trend for older age groups to have higher levels of lipopolysaccharide-specific IgA ASC responses. All age groups developed comparable MBC responses to V. cholerae lipopolysaccharide and cholera toxin B subunit at day 30. These findings suggest that young children are able to mount robust vibriocidal, plasma antibody, ASC, and MBC responses against V. cholerae O1, suggesting that under an optimal vaccination strategy, young children could achieve protective efficacy comparable to that induced in adults.

AB Vibrio cholerae O1 is a noninvasive enteric pathogen and serves as a model for studies of mucosal immunity. Although symptomatic V. cholerae infection induces durable protection against subsequent disease, vaccination with oral killed whole-cell V. cholerae stimulates less long-lasting protection against cholera. In this study, we demonstrated that cholera induces an early proinflammatory cellular immune response that results in priming of Th1- and Th17-type cytokine responses to ex vivo antigenic stimulation and an increase in the ratio of Th1 to Th2 CD4(+) T-cell responses. Comparable priming of Th1 and Th17 responses, with an increased ratio of Th1 to Th2 CD4(+) T-cell responses, was not observed in subjects who received two doses of the oral cholera vaccine Dukoral (a whole-cell cholera toxin B subunit containing [WC-CTB] vaccine). These findings suggest that natural V. cholerae infection induces an early, proinflammatory cellular immune response, despite the apparent lack of clinical signs of inflammation. The failure of the WC-CTB vaccine to activate equivalent, CD4(+) T-cell responses is a potential explanation for the shorter duration of protection following immunization with this vaccine. Additional studies are needed to determine whether these early T-cell-mediated events predict the subsequent duration of immunologic memory.

AB Prion diseases are infectious neurodegenerative disorders associated with the misfolded prion protein (PrP(Sc)), which appears to be the sole component of the infectious agent (termed prion). To produce disease, prions have to be absorbed into the body and reach sufficient quantities in the brain. Very little is known about the biological mechanisms controlling the initial fate of prions. Here, we studied the systemic pharmacokinetics and biodistribution of PrP(Sc) in vivo. After an intravenous injection of highly purified radiolabeled or native unlabeled PrP(Sc), the protein was eliminated rapidly from the serum (half-life of 3.24 h), mostly through tissue uptake. The quantity of intact PrP(Sc) reaching the brain was similar to 0.2% of the injected dose per gram of brain tissue (ID/g). The highest levels were found in liver (similar to 20% ID/g), spleen (similar to 13% ID/g), and kidney (similar to 7.4% ID/g). Cell surface PrP(C) does not appear to play a role in PrP(Sc) pharmacokinetics, since the infectious protein distributed similarly in wild-type and PrP-null mice. To measure tissue uptake kinetics and biodistribution accurately, vascular space in tissues was measured with radioactively labeled albumin coinjected with radioactively labeled PrP(Sc). Our results provide a fundamental pharmacokinetic characterization of PrP(Sc) in vivo, which may be relevant to estimate tissue risks and mechanisms of prion neuroinvasion and to identify novel therapeutic strategies.-Urayama, A., Morales, R., Niehoff, M.

AB Only a few of the interventions that target blue-collar workers have conducted formal analysis to evaluate the specific attributes of their intervention that are associated with success or failure. This study examined the role of dual hazard and decisional balance in the MassBUILT smoking cessation intervention. The authors conducted sets of multivariable linear and logistic regressions that examined if (a) the intervention was associated with changes in the psychosocial variables and (b) increase in psychosocial variables was associated with increase in smoking cessation. As hypothesized by the theoretical basis of the study, higher scores on both of the psychosocial variables were significantly associated with smoking cessation. However, the intervention did not change decisional balance and decreased dual hazard. The variables examined were important but were not mediators of the MassBUILT intervention and this could have contributed to the significant relapse in smoking among study participants.

AB Purpose: To describe the history, composition, and activities of the Radiation Injury Treatment Network (RITN). The Radiation Injury Treatment Network (R) is a cooperative effort of the National Marrow Donor Program and the American Society for Blood and Marrow Transplantation. The goals of RITN are to educate hematologists, oncologists, and stem cell transplant practitioners about their potential involvement in the response to a radiation incident and provide treatment expertise. Injuries to the marrow system readily occur when a victim is exposed to ionising radiation. This focus therefore leverages the expertise of these specialists who are accustomed to providing the intensive supportive care required by patients with a suppressed marrow function. Following a radiological incident, RITN centres may be asked to: Accept patient transfers to their institutions; provide treatment expertise to practitioners caring for victims at other centres; travel to other centres to provide medical expertise; or provide data on victims treated at their centres. Moving forward, it is crucial that we develop a coordinated interdisciplinary approach in planning for and responding to radiological and nuclear incidents. The ongoing efforts of radiation biologists, radiation oncologists, and health physicists can and should complement the efforts of RITN and government agencies.
Conclusion: RITN serves as a vital partner in preparedness and response efforts for potential radiological and nuclear incidents.

AB Background: Health literacy (HL) is associated with outcomes in many conditions, but little is known about its impact on arthritic diseases.
Objectives: We sought to determine whether HL is related to disease activity and severity in patients with rheumatoid arthritis (RA).
Methods: English-speaking adult RA patients were recruited for this cross-sectional study. Background information was ascertained by medical record review; Disease Activity Score 28 (DAS-28) scores were determined by providers; subjects completed the Multidimensional Health Assessment Questionnaire (MDHAQ), demographic questionnaires, and validated HL instruments, including the Short Test of Functional Health Literacy in Adults, Rapid Estimate of Adult Literacy in Medicine, and the single-item literacy screener. We used linear regression to assess whether HL was associated with MDHAQ and DAS-28 scores.
Results: One hundred ten subjects participated in the study. Limited HL was a common finding, especially among ethnic minorities. The single-item literacy screener results were predictive of lower MDHAQ scores by univariate regression analysis. Similar trends were observed for the Short Test of Functional Health Literacy in Adults and Rapid Estimate of Adult Literacy in Medicine. The relationship between the single-item literacy screener and MDHAQ remained statistically significant in multivariate analysis that controlled for the impact of demographic features and RA disease characteristics. Health literacy scores were not associated with DAS-28 scores.
Conclusions: Health literacy was independently associated with functional impairment in English-speaking RA patients at an urban safety-net clinic. This new finding suggests that RA functional status might be improved by strategies that target limited HL's causal pathways.

AB Objective: The objective of the study was to develop and test a survey of gout patients regarding their level of disease-related knowledge, to identify potential targets for patient education.
Methods: A 10-item questionnaire with readability at a Flesch-Kincaid grade level of 4.6 and Flesch reading ease of 83.9% was designed to address parameters considered important for patient participation in the management of gout. The questionnaire was primarily evaluated at the Veterans Affairs (VA) Medical Center in Philadelphia, but was also secondarily performed at 2 Chinese hospitals, the Sun Yat-sen Memorial Hospital of Zhong Shan University, Guangdong Province (GZ), and the Qingdao Municipal Hospital, Qingdao City, Shandong Province (QD). Demographic and questionnaire data by institution were evaluated using descriptive statistics, and significant differences were identified by W 2 and Fisher exact tests. Patient responses were displayed by each individual question and by the distribution of total scores. Kruskal-Wallis tests of significance were used for nonparametric or skewed data. Intraclass correlations (ICCs) were performed within the VA population to determine internal consistency of the individual questions. A high score was defined as greater than 7 (the median value). Multivariate regression models using demographic and clinical characteristics attempted to identify factors associated with correct answers to each question.
Results: Total correct score for individual patients varied widely at each institution with a mean (SD) and median (interquartile range [IQR]) scores in all 3 hospitals of 6.15 (2.25) and 7 (5-8), respectively. The average numbers of correct responses for each institution were 4.38 (SD, 3.04) (median, 4 [IQR, 2-7]) at GZ; 7.05 (SD, 1.37) (median, 8 [IQR, 6-8]) at QD; 6.21 (SD, 1.74) (median, 7 [IQR, 6-7]) at VA; P = 0.0010. Two questions (Q4 and Q10) were identified as difficult to understand by patients and showed poor ICC (ICC = 0.0000, P > 0.5) at the VA. Questions that were more difficult to answer were (1) Q3: What inside the joint causes attacks of gout? (GZ, 28.6%; QD, 7.7%; VA, 72.4%; P = 0.000); (2) Q8: How long should patients continue with serum uric acid-lowering drugs? (GZ, 19.1%; QD, 10.3%; VA, 82.7%; P = 0.000); (3) Q6: The ideal serum uric acid to aim at during treatment? (GZ, 42.8%; QD, 89.7%; and VA, 17.2%; P = 0.000); and (4) Q5: Which drugs can lower serum uric acid? (GZ, 61.9%; QD, 89.7%; VA, 51.7%; P = 0.002).
Conclusions: This study describes an easy-to-read 10-item questionnaire that can identify important knowledge gaps in patients with gout. This can be the first step in designing educational interventions to improve patient understanding and improve clinical care.

AB Most patients with autosomal dominant pseudohypoparathyroidism type Ib (AD-PHP-Ib) carry maternally inherited microdeletions upstream of GNAS that are associated with loss of methylation restricted to GNAS exon A/B. Only few AD-PHP-Ib patients carry microdeletions within GNAS that are associated with loss of all maternal methylation imprints. These epigenetic changes are often indistinguishable from those observed in patients affected by an apparently sporadic PHP-Ib form that has not yet been defined genetically. We have now investigated six female patients affected by PHP-Ib (four unrelated and two sisters) with complete or almost complete loss of GNAS methylation, whose healthy children (11 in total) showed no epigenetic changes at this locus. Analysis of several microsatellite markers throughout the 20q13 region made it unlikely that PHP-Ib is caused in these patients by large deletions involving GNAS or by paternal uniparental isodisomy or heterodisomy of chromosome 20 (patUPD20). Microsatellite and single-nucleotide variation (SNV) data revealed that the two affected sisters share their maternally inherited GNAS alleles with unaffected relatives that lack evidence for abnormal GNAS methylation, thus excluding linkage to this locus. Consistent with these findings, healthy children of two unrelated sporadic PHP-Ib patients had inherited different maternal GNAS alleles, also arguing against linkage to this locus. Based on our data, it appears plausible that some forms of PHP-Ib are caused by homozygous or compound heterozygous mutation(s) in an unknown gene involved in establishing or maintaining GNAS methylation.

AB In pseudohypoparathyroidism (PHP), PTH resistance results from impairment of signal transduction of G protein-coupled receptors caused by a deficiency of the Gs alpha-cAMP signaling cascade due to diminished Gs alpha activity in maternally imprinted tissues. In PHP-Ia, inactivating mutations of the GNAS gene lead to haploinsufficiency in some tissues with biallelic expression, so in addition to PHP, Albright's hereditary osteodystrophy (AHO) is also present. In PHP-Ib, caused by methylation defects at the GNAS locus, diminished Gs alpha activity was thought to be limited to maternally imprinted tissues, such as the renal proximal tubule and the thyroid, leading to a lack of AHO. Recently, we demonstrated methylation defects in patients with AHO signs, indicating a connection between epigenetic changes and AHO. Our objective was to determine Gs alpha activity in erythrocyte membranes in patients with epigenetic defects at the GNAS locus compared to normal controls and patients with inactivating GNAS mutations. Gs alpha activity and expression, mutation of the GNAS locus, and methylation status were studied in patients with PHP and mild signs of AHO (PHP-Ia: 12; PHP-Ib: 17, of which 8 had some features of AHO). Then, we statistically compared the Gs alpha activity of the different PHP subtypes. Patients with methylation defects at the GNAS locus show a significant decrease in erythrocyte Gs alpha activity compared to normal controls (PHP-Ib versus controls, p<.001). This was significantly lower in patients with AHO signs (PHP-Ib+mild-AHO versus PHP-Ib, p<.05). Our research shows that PHP-Ia and PHP-Ib classification is not only overlapped genetically, as reported, but also in terms of Gs alpha activity. Reduced expression of GNAS due to methylation defects could downregulate Gs alpha activity in other tissues beyond those described and could also be causative of AHO.

AB Objectives: The current study tested opposing predictions stemming from the failure and acting out theories of depression-delinquency covariation. Method: Participants included a nationwide longitudinal sample of adolescents (N = 3,604) ages 12 to 17. Competing models were tested with cohort-sequential latent growth curve modeling to determine whether depressive symptoms at age 12 (baseline) predicted concurrent and age-related changes in delinquent behavior, whether the opposite pattern was apparent (delinquency predicting depression), and whether initial levels of depression predict changes in delinquency significantly better than vice versa. Results: Early depressive symptoms predicted age-related changes in delinquent behavior significantly better than early delinquency predicted changes in depressive symptoms. In addition, the impact of gender on age-related changes in delinquent symptoms was mediated by gender differences in depressive symptom changes, indicating that depressive symptoms are a particularly salient risk factor for delinquent behavior in girls. Conclusion: Early depressive symptoms represent a significant risk factor for later delinquent behavior-especially for girls-and appear to be a better predictor of later delinquency than early delinquency is of later depression. These findings provide support for the acting out theory and contradict failure theory predictions.

AB The MYC oncogenic transcription factor is overexpressed in most human cases of T cell acute lymphoblastic leukemia (T-ALL), often downstream of mutational NOTCH1 activation. Genetic alterations in the PTEN-PI3K-AKT pathway are also common in T-ALL. We generated a conditional zebrafish model of T-ALL in which 4-hydroxytamoxifen (4HT) treatment induces MYC activation and disease, and withdrawal of 4HT results in T-ALL apoptosis and tumor regression. However, we found that loss-of-function mutations in zebrafish pten genes, or expression of a constitutively active Akt2 transgene, rendered tumors independent of the MYC oncogene and promoted disease progression after 4HT withdrawal. Moreover, MYC suppresses pten mRNA levels, suggesting that Akt pathway activation downstream of MYC promotes tumor progression. Our findings indicate that Akt pathway activation is sufficient for tumor maintenance in this model, even after loss of survival signals driven by the MYC oncogene.

AB Immunoglobulin class switch recombination (CSR) is initiated by double-stranded DNA breaks (DSBs) in switch regions triggered by activation-induced cytidine deaminase (AID). Although CSR correlates with epigenetic modifications at the IgH locus, the relationship between these modifications and AID remains unknown. In this study, we show that during CSR, AID forms a complex with KAP1 (KRAB domain-associated protein 1) and HP1 (heterochromatin protein 1) that is tethered to the donor switch region (S mu) bearing H3K9me3 (trimethylated histone H3 at lysine 9) in vivo. Furthermore, in vivo disruption of this complex results in impaired AID recruitment to S mu, inefficient DSB formation, and a concomitant defect in CSR but not in somatic hypermutation. We propose that KAP1 and HP1 tether AID to H3K9me3 residues at the donor switch region, thus providing a mechanism linking AID to epigenetic modifications during CSR.

AB Purpose: To characterize the DDIF (Decay due to Diffusion in the Internal Field) method using intact animal trabecular bone specimens of varying trabecular structure and porosity, under ex vivo conditions closely resembling in vivo physiological conditions. The DDIF method provides a diffusion contrast which is related to the surface-to-volume ratio of the porous structure of bones. DDIF has previously been used successfully to study marrow-free trabecular bone, but the DDIF contrast hitherto had not been tested in intact specimens containing marrow and surrounded by soft tissue.
Materials and Methods: DDIF imaging was implemented on a 4.7 Tesla (T) small-bore, horizontal, animal scanner. Ex vivo results on fresh bone specimens containing marrow were obtained at body temperature. Control measurements were carried out in surrounding tissue and saline.
Results: Significant DDIF effect was observed for trabecular bone samples, while it was considerably smaller for soft tissue outside the bone and for lipids. Additionally, significant differences were observed between specimens of different trabecular structure.
Conclusion: The DDIF contrast is feasible despite the reduction of the diffusion constant and of T(1) in such conditions, increasing our confidence that DDIF imaging in vivo may be clinically viable for bone characterization.

RANDOMIZED-TRIAL; POSTURAL CHANGES
AB Purpose: To determine whether topically applied brimonidine affects the retinal hemodynamic autoregulatory response to posture change in patients with normal tension glaucoma.
Methods: Six patients with normal tension glaucoma (primary open-angle glaucoma and maximum untreated intraocular pressure < 22 mmHg) in each eye were studied. We retrospectively reviewed retinal hemodynamic data acquired when the patients were off and on treatment with brimonidine 0.15% (twice a day, both eyes) during the course of their care. At each testing session, vessel diameter and blood speed at the same site along the inferior temporal retinal artery of 1 eye were measured while sitting, while reclining for 30 min, and again while sitting using a retinal laser Doppler instrument. Blood flow was computed automatically. Brachial artery blood pressure and heart rate were also measured. The Wilcoxon signed rank test was used to assess the statistical significance of the differences in each measured parameter while subjects were on and off brimonidine.
Results: Off brimonidine, the mean blood flow rate increased by 68.0% +/- 34.3% (range: + 17% to + 108%) after 30 min in reclined posture compared to baseline-seated measures. On brimonidine, the mean blood flow rate increased by 8.9% +/- 16.8% (range: - 9.7 to + 28.0%) after 30 min in reclined posture compared to baseline-seated measures. The difference in the posture-induced changes for blood flow rate while on brimonidine compared to off brimonidine was statistically significant (P = 0.027).
Conclusions: Off brimonidine, the patients exhibited marked increases in retinal blood flow while reclining. On brimonidine, the hemodynamic changes were consistent with normal autoregulatory control of retinal blood flow.

DT Article
ID OCULAR HYPERTENSION; GLAUCOMA; LATANOPROST; TRAVOPROST; EFFICACY; TRIAL
AB Purpose: To compare intraocular pressure (IOP) reduction profiles of bimatoprost 0.03% administered every other night (QOD-HS) compared with every night (QHS) in patients with primary open angle glaucoma and pseudoexfoliation glaucoma.
Methods: A retrospective chart review of 68 eyes of 45 consecutive patients who were switched from QHS to QOD-HS bimatoprost due to intolerable conjunctival hyperemia between May 2005 and May 2008. IOP in the morning (AM) and afternoon (PM) of the next day after administration (day 1) and the day after (day 2) on QOD-HS regimen was compared with IOP in the AM and PM when they were on QHS regimen, 4-6 weeks after switching to QOD-HS.
Results: Mean IOPs on QHS bimatoprost were 15.9 +/- 3.4mm Hg in the AM and 15.5 +/- 2.7mm Hg in the PM, whereas mean IOPs on QOD-HS were 14 +/- 2mm Hg (AM) and 14.2 +/- 2.5mm Hg (PM) on day 1, and 14.7 +/- 2.6mm Hg (AM) and 14.4 +/- 2.4mm Hg (PM) on day 2 after administration. Differences between IOP fluctuation on QHS and QOD-HS days 1 and 2, respectively, were not significant (P = 0.87 and 0.94).
Conclusion: Every other night dosing of bimatoprost was effective in controlling IOP in this select group of patients with primary open angle glaucoma and pseudoexfoliation glaucoma who had troublesome side effects on bimatoprost 0.03% QHS regimen, and may be considered as an alternative to every day treatment.

AB Background: Reports describe patient and health care system benefits when clinicians engage in end-of-life conversations with patients diagnosed with life-limiting illnesses, yet most clinicians focus on life-preserving treatments and avoid conversations about end-of-life care. We describe patient-clinician communication practices about end-of-life care in patients with chronic obstructive pulmonary disease (COPD) using self-report questionnaires to: (1) characterize the content of patient-clinician communication about end-of-life care from the patient perspective, including topics that were not addressed and ratings of the quality of the communication for topics discussed and (2) determine whether clinician characteristics was associated with the absence of specific communication items addressed.
Methods: Cross-sectional study of outpatients (n = 376) who completed the Quality of Communication (QOC) questionnaire (outcome measure). The primary exposure was clinician training. We used logistic regression. All tests were two-tailed and p < 0.05 was considered significant.
Results: Clinicians (n = 92) were staff physicians (33.7%), physician trainees (35.9%), and advanced practice nurses (30.4%). Patients were older (mean age, 69.4 years, standard deviation [SD] 10.0); white (86%) men (97%) with severe COPD (mean forced expiraory volume in 1 second [FEV(1)] percent predicted 50%, SD 20). All end-of-life topics were underaddressed. Four topics were not addressed 77%-94% of the time. None of the QOC items varied significantly by clinician type in adjusted logistic regression.
Conclusions: All end-of-life communication topics were underaddressed by clinicians, regardless of training, with four topics particularly unlikely to be discussed. End-of-life topics that are important to patients should be targeted for an intervention to facilitate improvement in clinicians' communication skills and practice and may improve patient satisfaction with clinician communication.

Methods: Using the Surveillance, Epidemiology, and End Results-Medicare linked database, we identified 7879 patients aged 65 years or older who died of advanced non-small-cell lung cancer from 1991 through 1999 after surviving for at least 3 months from their cancer diagnoses. Length of hospice admission post-cancer diagnosis and indicators of aggressive end-of-life care were ascertained based on claims data. We evaluated overall survival and care near death after controlling for baseline characteristics by using propensity score (PS) and instrumental variable analyses (IVA).
Results: Hospice patients were older, more likely to be non-Hispanic white and female, more likely to reside in urban areas with high hospice availability and higher socioeconomic status, more likely to be treated in a teaching hospital, and received less aggressive end-of-life care compared to nonhospice patients. Among hospice patients, those experiencing short-term hospice admissions within 3 days of death were more likely to be male, reside in urban areas, be treated in a teaching hospital, and receive more aggressive end-of-life care. PS analysis found that survival favored hospice patients slightly relative to nonhospice patients by 5.0 percentage points (25.7% versus 20.7%) at 1 year and 1.4 percentage points (6.9% versus 5.5%) at 2 years postdiagnosis (p < 0.001), while there was no significant difference between those with short-and longer duration hospice stays (p = 1.00). IVA confirmed these findings.
Conclusions: Hospice enrollment did not compromise length of survival following advanced lung cancer diagnosis.

AB Purpose: This study examined the influence of presentation level and mild-to-moderate hearing loss on the identification of a set of vowel tokens systematically varying in the frequency locations of their second and third formants.
Method: Five listeners with normal hearing (NH listeners) and five listeners with hearing impairment (HI listeners) identified synthesized vowels that represented both highly identifiable and ambiguous examples of /I/, /U/, and /(sic)/.
Results: Response patterns of NH listeners showed significant changes, with an increase in presentation level from 75 dB SPL to 95 dB SPL, including increased category overlap. HI listeners, listening only at the higher level, showed greater category overlap than normal and overall identification patterns that differed significantly from those of NH listeners. Excitation patterns based on estimates of auditory filters suggested smoothing of the internal representations, resulting in impaired formant resolution.
Conclusions: Both increased presentation level for NH listeners and the presence of hearing loss produced a significant change in vowel identification for this stimulus set. Major differences were observed between NH listeners and HI listeners in vowel category overlap and in the sharpness of boundaries between vowel tokens. It is likely that these findings reflect imprecise internal spectral representations due to reduced frequency selectivity.

AB Purpose: To determine factors influencing the number of acquired scan series and subsequently the radiation dose and time during computed tomography (CT)-guided lung biopsies.
Materials and Methods: This Health Insurance Portability and Accountability Act-compliant, institutional review board-approved, retrospective study reviewed 50 consecutive procedures. Each procedure was separated into the following steps: trajectory planning, needle placement, needle insertion (extrapulmonary and intrapulmonary), and sampling and follow-up. The number of scan series, time, and radiation dose were calculated for each procedure and its steps. The effects of patient characteristics (age, sex, history of surgery that violated the pleura), procedure characteristics (needle-pleural angle, patient position), and lesion characteristics (size, depth, lobar location) on the number of scan series for the procedure and each step were evaluated using stepwise linear regression. The overall diagnostic accuracy, pneumothorax rate, and chest tube insertion rate were also calculated.
Results: The mean number of total CT scans was 21, the mean effective dose was 14 mSv, and the mean entrance skin dose was 249 mGy. On average, trajectory planning and needle insertion contributed most to the number of scan series (18.5% and 52.9%, respectively). For trajectory planning, a smaller lesion size and shallower needle-pleural angle were associated with an increased number of scans (R(2)=0.200, P=0.005). During needle insertion, smaller lesions were associated with increased scanning (R(2)=0.296, P<0.001), with both smaller and deeper lesions associated with an increased number of scans during the intrapulmonary component (R(2)=0.372, P<0.001). For the entire procedure, smaller lesions were associated with an increased number of scans (R(2)=0.12, P=0.01).
Conclusion: Lesions that are smaller or deeper in the lung result in a higher number of CT scans, resulting in increased radiation dose and procedure time, with most of these performed during the needle insertion step.

AB Mammals have two principal types of fat. White adipose tissue primarily serves to store extra energy as triglycerides, whereas brown adipose tissue is specialized to burn lipids for heat generation and energy expenditure as a defence against cold and obesity(1,2). Recent studies have demonstrated that brown adipocytes arise in vivo from a Myf5-positive, myoblastic progenitor by the action of Prdm16 (PR domain containing 16). Here, we identified a brown-fat-enriched miRNA cluster, MiR-193b-365, as a key regulator of brown fat development. Blocking miR-193b and/or miR-365 in primary brown preadipocytes markedly impaired brown adipocyte adipogenesis by enhancing Runx1t1 (runt-related transcription factor 1; translocated to, 1) expression, whereas myogenic markers were significantly induced. Forced expression of Mir193b and/or Mir365 in C2C12 myoblasts blocked the entire programme of myogenesis, and, in adipogenic conditions, miR-193b induced myoblasts to differentiate into brown adipocytes. Mir193b-365 was upregulated by Prdm16 partially through Ppar alpha. Our results demonstrate that Mir193b-365 serves as an essential regulator for brown fat differentiation, in part by repressing myogenesis.

AB Focal segmental glomerulosclerosis (FSGS) is a cause of proteinuric kidney disease, compromising both native and transplanted kidneys. Treatment is limited because of a complex pathogenesis, including unknown serum factors. Here we report that serum soluble urokinase receptor (suPAR) is elevated in two-thirds of subjects with primary FSGS, but not in people with other glomerular diseases. We further find that a higher concentration of suPAR before transplantation underlies an increased risk for recurrence of FSGS after transplantation. Using three mouse models, we explore the effects of suPAR on kidney function and morphology. We show that circulating suPAR activates podocyte beta(3) integrin in both native and grafted kidneys, causing foot process effacement, proteinuria and FSGS-like glomerulopathy. Our findings suggest that the renal disease only develops when suPAR sufficiently activates podocyte beta(3) integrin. Thus, the disease can be abrogated by lowering serum suPAR concentrations through plasmapheresis, or by interfering with the suPAR-beta(3) integrin interaction through antibodies and small molecules targeting either uPAR or beta(3) integrin. Our study identifies serum suPAR as a circulating factor that may cause FSGS.

AB Progress in understanding, diagnosis, and treatment of coronary artery disease (CAD) has been hindered by our inability to observe cells and extracellular components associated with human coronary atherosclerosis in situ. The current standards for microstructural investigation, histology and electron microscopy are destructive and prone to artifacts. The highest-resolution intracoronary imaging modality, optical coherence tomography (OCT), has a resolution of similar to 10 mu m, which is too coarse for visualizing most cells. Here we report a new form of OCT, termed micro-optical coherence tomography (mu OCT), whose resolution is improved by an order of magnitude. We show that mu OCT images of cadaver coronary arteries provide clear pictures of cellular and subcellular features associated with atherogenesis, thrombosis and responses to interventional therapy. These results suggest that mu OCT can complement existing diagnostic techniques for investigating atherosclerotic specimens, and that mu OCT may eventually become a useful tool for cellular and subcellular characterization of the human coronary wall in vivo.

AB Objectives: Event-related potentials (ERPs) can reflect differences in brain electrophysiology underlying cognitive functions in brain disorders such as dementia and mild cognitive impairment. To identify individuals at risk for Alzheimer disease (AD) we used high-density ERPs to examine brain physiology in young presymptomatic individuals (average age 34.2 years) who carry the E280A mutation in the presenilin-1 (PSEN1) gene and will go on to develop AD around the age of 45.
Methods: Twenty-one subjects from a Colombian population with familial AD participated: 10 presymptomatic subjects positive for the PSEN1 mutation (carriers) and 11 siblings without the mutation (controls). Subjects performed a visual recognition memory test while 128-channel ERPs were recorded.
Results: Despite identical behavioral performance, PSEN1 mutation carriers showed less positivity in frontal regions and more positivity in occipital regions, compared to controls. These differences were more pronounced during the 200-300 msec period. Discriminant analysis at this time interval showed promising sensitivity (72.7%) and specificity (81.8%) of the ERP measures to predict the presence of AD pathology.
Conclusions: Presymptomatic PSEN1 mutation carriers show changes in brain physiology that can be detected by high-density ERPs. The relative differences observed showing greater frontal positivity in controls and greater occipital positivity in carriers indicates that control subjects may use frontally mediated processes to distinguish between studied and unstudied visual items, whereas carriers appear to rely more upon perceptual details of the items to distinguish between them. These findings also demonstrate the potential usefulness of ERP brain correlates as preclinical markers of AD. Neurology (R) 2011;77:469-475

AB Purpose: We studied the 3-year efficacy and safety results of a 4-year study evaluating fluocinolone acetonide (FA) intravitreal implants in eyes with persistent or recurrent diabetic macular edema (DME).
Design: Prospective, evaluator-masked, controlled, multicenter clinical trial.
Participants: We included 196 eyes with refractory DME.
Methods: Patients were randomized 2: 1 to receive 0.59-mg FA implant (n = 127) or standard of care (SOC additional laser or observation; n = 69). The implant was inserted through a pars plana incision. Visits were scheduled on day 2, weeks 1, 3, 6, 12, and 26, and thereafter every 13 weeks through 3 years postimplantation.
Main Outcome Measures: The primary efficacy outcome was >= 15-letter improvement in visual acuity (VA) at 6 months. Secondary outcomes included resolution of macular retinal thickening and Diabetic Retinopathy Severity Score (DRSS). Safety measures included incidence of adverse events (AEs).
Results: Overall, VA improved >= 3 lines in 16.8% of implanted eyes at 6 months (P = 0.0012; SOC, 1.4%); in 16.4% at 1 year (P = 0.1191; SOC, 8.1%); in 31.8% at 2 years (P = 0.0016; SOC, 9.3%); and in 31.1% at 3 years (P = 0.1566; SOC, 20.0%). The number of implanted eyes with no evidence of retinal thickening at the center of the macula was higher than SOC eyes at 6 months (P < 0.0001), 1 year (P < 0.0001; 72% vs 22%), 2 years (P = 0.016), and 3 years (P = 0.861). A higher rate of improvement and lower rate of decline in DRSS occurred in the implanted group versus the SOC group at 6 months (P = 0.0006), 1 year (P = 0.0016), 2 years (P = 0.012), and 3 years (P = 0.0207). Intraocular pressure (IOP) >= 30 mmHg was recorded in 61.4% of implanted eyes (SOC, 5.8%) at any time and 33.8% required surgery for ocular hypertension by 4 years. Of implanted phakic eyes, 91% (SOC, 20%) had cataract extraction by 4 years.
Conclusions: The FA intravitreal implant met the primary and secondary outcomes, with significantly improved VA and DRSS and reduced DME. The most common AEs included cataract progression and elevated IOP. The 0.59-mg FA intravitreal implant may be an effective treatment for eyes with persistent or recurrent DME.

AB OBJECTIVE: Oxygen therapy for infants and small children in developing countries is often not available. Entrainment devices may provide an accurate and precise concentration of oxygen when used at the flow rates appropriate for infants and small children.
METHODS: A continuously adjustable entrainment device was tested to determine the concentrations and flows of oxygen delivered by using low inlet flow rates suitable for therapy for infants and small children and 3 distinct oxygen delivery systems that varied in their resistive load.
RESULTS: The use of long and large bore, low resistance tubing (similar to a mask) resulted in the delivery of oxygen concentrations that tracked closely (accurate and precise) to values indicated by the entrainment device. The directly connected system with lower resistance (similar to a hood) produced a similar profile of concentrations and flow rates to the large bore tubing but with even greater accuracy. The use of a long and narrow tubing with higher resistance (similar to a cannula) did not deliver accurate oxygen concentrations. In fact, this high-resistance system failed to work as intended, and instead of entraining air, a large proportion (sometimes >50%) of the oxygen delivered to the entrainment device was ejected through its vents.
CONCLUSIONS: Entrainment devices can deliver accurate oxygen concentrations at low flow rates if used with low resistance delivery systems; however, entrainment devices are not suitable for use with high resistance delivery systems such as a standard nasal cannula. Pediatrics 2011;128:e382-e387

DE Teamwork; Patient safety; Management; Leadership
AB We developed a training program to introduce managers and informal leaders of healthcare organizations to key concepts of teamwork, safety leadership, and simulation to motivate them to act as leaders to improve safety within their sphere of influence. This report describes the simulation scenario and debriefing that are core elements of that program. Twelve teams of clinician and nonclinician managers were selected from a larger set of volunteers to participate in a 1-day, multielement training program. Two simulation exercises were developed: one for teams of nonclinicians and the other for clinicians or mixed groups. The scenarios represented two different clinical situations, each designed to engage participants in discussions of their safety leadership and teamwork issues immediately after the experience. In the scenarios for nonclinicians, participants conducted an anesthetic induction and then managed an ethical situation. The scenario for clinicians simulated a consulting visit to an emergency room that evolved into a problem-solving challenge. Participants in this scenario had a limited time to prepare advice for hospital leadership on how to improve observed safety and cultural deficiencies. Debriefings after both types of scenarios were conducted using principles of "debriefing with good judgment." We assessed the relevance and impact of the program by analyzing participant reactions to the simulation through transcript data and facilitator observations as well as a postcourse questionnaire. The teams generally reported positive perceptions of the relevance and quality of the simulation with varying types and degrees of impact on their leadership and teamwork behaviors. These kinds of clinical simulation exercises can be used to teach healthcare leaders and managers safety leadership and teamwork skills and behaviors. (Sim Healthcare 6: 231-238, 2011)

AB Study design: Review.
Objectives: In subjects with spinal cord injury (SCI), there is strong evidence for platelet hyperactivity, which may stimulate atherosclerosis and coronary heart disease (CHD). The literature was reviewed.
Background: Individuals with SCI develop premature CHD. In addition to the conventional risk factors associated with CHD, there are pathologic hematological factors involved in atherogenesis that are similar to those that have been demonstrated in individuals with diabetes, and these hematological factors might affect individuals with SCI. One such hematological factor, platelet aggregation, is essential for the development of CHD, which results from thrombus formation in the coronary vasculature. Prostacyclin (PGI(2)) is a potent inhibitor of platelet aggregation and is thought to have a beneficial role in inhibiting atherogenesis; therefore, it is possible that individuals with SCI have impaired PGI(2) receptor function.
Methods: We reviewed the literature by conducting a search using PubMed (1970-2007).
Results: Acute thrombosis is emerging as an important factor in the etiology of CHD and therefore could mediate the risk of CHD in persons with SCI, in addition to previously known risk factors such as hyperlipidemia, hypertension, hyperlipidemia, diabetes mellitus and hyperinsulinemia. Because PGI(2) may retard atherogenesis through its inhibitory effects on platelet function, we discuss the effects of PGI(2) on platelets in persons with SCI in this review.
Conclusions Subjects with chronic SCI develop abnormal platelet function, resulting in the production of atherogenic and thrombogenic factors for the following reasons: (1) the PGI(2) and insulin receptors on their platelets are impaired; (2) thrombin generation and platelet-derived growth factor release are elevated; (3) insulin-induced nitric oxide production by platelets is markedly impaired; and (4) a circulating antibody (immunoglobulin G (IgG)) blocks the antithrombotic effect of both insulin and PGI(2) receptors. Thus, this IgG molecule is thought to be one of the pathological mediators of the increased incidence of CHD in individuals with SCI.

AB Objective: Administration after spinal cord injury (SCI) of methylprednisolone (MP) for 24-48h has been suggested to improve functional outcome. The safety of this approach has been questioned because of the known adverse effects of glucocorticoids on skeletal muscle and the immune system. The purpose of this study was to explicitly test adverse effects of regimen of MP administration on skeletal muscle.
Study design: Male rats underwent spinal cord transection at T9-T10, followed by an intravenous injection of MP and subsequent infusion of MP for 24 h.
Results: MP significantly reduced the weight of the triceps, soleus, plantaris and gastrocnemius muscles, with the greatest effect being a 63% decrease in triceps weight (for example, muscle above the level of lesion) at 7 days; below the level of lesion, gastrocnemius weight was reduced by 33% by SCI alone, and by 45% by SCI and MP. Centralized nuclei were found in myofibers of the gastrocnemius and triceps from the MP-SCI group, but not other groups. MP increased expression in the triceps, soleus and plantaris of FOXO1, MAFbx, MuRF1 and REDD1 at 1 day, and, in plantaris, at 7 days.
Conclusions: Thus, 1 day of MP at a dose comparable to those routinely employed in clinical practice immediately after SCI resulted in marked atrophy of functionally intact muscle above the level of lesion, and worsened atrophy of paralyzed muscle below the level of lesion, associated with elevations in expression of four genes involved in pathways associated with muscle atrophy.

attack; stroke risk
ID ISCHEMIC ATTACK; MINOR STROKE; POPULATION; RECURRENCE; SCORE; VALIDATION
AB Background and Purpose-The risk of stroke shortly after transient ischemic attack with infarction on diffusion-weighted images, also known as transient symptoms with infarction (TSI), is substantially higher than is the risk after imaging-normal transient ischemic attack. We sought to assess the utility of a Web-based recurrence risk estimator (RRE; http://www.nmr.mgh.harvard.edu/RRE/) originally developed for use in patients with ischemic stroke for predicting 7-day risk of stroke in patients with TSI.
Methods-We calculated RRE and ABCD(2) scores in a retrospective series of 257 consecutive patients with TSI diagnosed by diffusion-weighted images within 24 hours of symptom onset. We defined subsequent stroke as clinical deterioration associated with new infarction spatially distinct from the index lesion. We assessed the predictive performance of each model by computing the area under receiver-operating characteristics curve.
Results-Over 7-day follow-up, 16 patients developed a recurrent stroke (6.2%). The sensitivity and specificity of an RRE score of >= 2 for predicting 7-day stroke risk were 87% and 73%, respectively. The area under the receiver-operating characteristics curve was 0.85 (95% CI, 0.78-0.92) for RRE and 0.57 (95% CI, 0.45-0.69) for ABCD(2) score (z-test; P<0.001).
Conclusions-The RRE score seems to predict 7-day risk of stroke after a TSI. If further validated in larger data sets, the RRE score could be useful in identifying high-risk patients with TSI who may benefit from early intervention with targeted stroke prevention strategies.

AB Background and Purpose-Quality of care delivered in the inpatient and ambulatory settings may be correlated within an integrated health system such as the Veterans Health Administration. We examined the correlation between stroke care quality at hospital discharge and within 6 months postdischarge.
Methods-We conducted a cross-sectional hospital-level correlation analyses of chart-abstracted data for 3467 veterans discharged alive after an acute ischemic stroke from 108 Veterans Health Administration medical centers and 2380 veterans with postdischarge follow-up within 6 months in fiscal year 2007. Four risk-standardized processes of care represented discharge care quality: prescription of antithrombotic and antilipidmic therapy, anticoagulation for atrial fibrillation, and tobacco cessation counseling along with a composite measure of defect-free care. Five risk-standardized intermediate outcomes represented postdischarge care quality: achievement of blood pressure, low-density lipoprotein, international normalized ratio, and glycosylated hemoglobin target levels, and delivery of appropriate treatment for poststroke depression along with a composite measure of achieved outcomes.
Results-Median risk-standardized composite rate of defect-free care at discharge was 79%. Median risk-standardized postdischarge rates of achieving goal were 56% for blood pressure, 36% for low-density lipoprotein, 41% for international normalized ratio, 40% for glycosylated hemoglobin, and 39% for depression management and the median risk-standardized composite 6-month outcome rate was 44%. The hospital composite rate of defect-free care at discharge was correlated with meeting the low-density lipoprotein goal (r = 0.31; P = 0.007) and depression management (r = 0.27; P = 0.03) goal but was not correlated with blood pressure, international normalized ratio, glycosylated hemoglobin goals, nor with the composite measure of achieved postdischarge outcomes (probability values >0.13).
Conclusions-Hospital discharge care quality was not consistently correlated with ambulatory care quality. (Stroke. 2011;42:2269-2275.)

AB Background and Purpose-Delayed paraplegia remains a devastating complication after ischemic spinal cord injury associated with aortic surgery and trauma. Although apoptosis has been implicated in the pathogenesis of delayed neurodegeneration, mechanisms responsible for the delayed paraplegia remain incompletely understood. The aim of this study was to elucidate the role of apoptosis in delayed motor neuron degeneration after spinal cord ischemia.
Methods-Mice were subjected to spinal cord ischemia induced by occlusion of the aortic arch and left subclavian artery for 5 or 9 minutes. Motor function in the hind limb was evaluated up to 72 hours after spinal cord ischemia. Histological studies were performed to detect caspase-3 activation, glial activation, and motor neuron survival in the serial spinal cord sections. To investigate the impact of caspase-3 activation on spinal cord ischemia, outcome of the spinal cord ischemia was examined in mice deficient for caspase-3.
Results-In wild-type mice, 9 minutes of spinal cord ischemia caused immediate paraplegia, whereas 5 minutes of ischemia caused delayed paraplegia. Delayed paraplegia after 5 minutes of spinal cord ischemia was associated with histological evidence of caspase-3 activation, reactive astrogliosis, microglial activation, and motor neuron loss starting at approximately 24 to 48 hours after spinal cord ischemia. Caspase-3 deficiency prevented delayed paraplegia and motor neuron loss after 5 minutes of spinal cord ischemia, but not immediate paraplegia after 9 minutes of ischemia.
Conclusions-The present results suggest that caspase-3 activation is required for delayed paraplegia and motor neuron degeneration after spinal cord ischemia. (Stroke. 2011;42:2302-2307.)

AB Background: Stressful life events in childhood during critical periods of development have long-term psychological and neurobiological sequelae, which may affect risk for HIV infection across the life course.
Methods: Data were from a nationally representative sample of 13,274 US men (National Epidemiologic Survey on Alcohol and Related Conditions, 2004-2005). Weighted multivariable logistic regression models examined (1) the association of childhood violent events before age 18 on 12-month incident HIV infection and (2) whether posttraumatic stress disorder (PTSD) diagnosis (clinical interview) mediated the association between early life events and HIV.
Results: Overall, the 12-month HIV incidence was,1% (0.35%); 44% of new infections were among racial/ethnic minorities and 31% among men who have sex with men). One-third of the sample (33.5%) reported one or more early life stressors (physical abuse, sexual abuse, neglect, verbal violence, or witnessed violence). In a weighted multivariable logistic regression model adjusted for age, education, family's socioeconomic position, and sexual behaviors, each additional early life violent event was associated with an elevated odds of HIV infection [adjusted odds ratio (aOR) = 1.32; 95% confidence interval (CI): 1.16 to 1.50]. Adding PTSD to this adjusted model, PTSD was highly associated with incident HIV infection (aOR = 5.75; 95% CI: 4.76 to 6.95). There was evidence that PTSD partially mediated the relationship between early life events and HIV (aOR = 1.14; 95% CI: 1.02 to 1.28).
Conclusions: Experiencing early life violent family stressors was associated with HIV infection among men. Early life events and HIV infection were mediated by PTSD, which has implications for understanding disparities in HIV infection. Interventions are urgently needed that address the long-term sequelae of childhood violence.

ID CARE
AB Physician satisfaction is an important contributor to a well-functioning health system. Mohr and Burgess report that physicians in the Veterans Health Administration (VA) who spend time in research have greater overall job satisfaction, that satisfaction tracks with aggregate facility research funding, and that satisfaction is higher among physicians working in VA facilities located on the same campus or within walking distance of an affiliated medical school. An environment conducive to research therefore not only advances science but also seems to be a key element of physician satisfaction. In addition to advancing scientific discovery and promoting greater physician satisfaction, these findings suggest that an environment of discovery and learning may yield benefits beyond specific academic endeavors and contribute more broadly to supporting health system performance.

AB Purpose
Research conducted by physicians generates knowledge and has led to important advances and changes in the health care system. Physician retention is a concern facing many health care systems, and job satisfaction and attitudes play a role in retention. This study examined whether physicians who are involved with research have greater job satisfaction and more positive job characteristics perceptions.
Method
Cross-sectional analysis examined this research question using a sample of 7,734 physicians across 135 medical centers in the Department of Veterans Affairs (VA) in 2008. Using existing survey results, ratings on job characteristics (job autonomy, skill development opportunities, work and family balance, and performance feedback) and job satisfaction were regressed on research involvement in a multilevel hierarchical generalized linear model. The model controlled for physician-level characteristics and organization-level characteristics related to research activities.

Analyses revealed that physicians who spent part of their time involved with research activities were more likely to report favorable job characteristics ratings. Physicians involved with research were also more likely to be satisfied with their job. Physicians who worked in medical centers with greater levels of research funding were more likely to report favorable ratings for job characteristics and job satisfaction.
Conclusions
Involvement with research was associated with more favorable job characteristics and job satisfaction perceptions among physicians in VA. Although there is a time and opportunity cost involved with research, medical centers that provide physicians with the opportunity to conduct research may have a more satisfied workforce.

AB Background: Recent reports have suggested a close relationship between education and health, including mortality, in the United States.
Study Design: Observational cohort.
Setting & Participants: We studied 61,457 participants enrolled in a national health screening initiative, the National Kidney Foundation's Kidney Early Evaluation Program (KEEP).
Predictor: Self-reported educational attainment.
Outcomes: Chronic diseases (hypertension, diabetes, cardiovascular disease, reduced kidney function, and albuminuria) and mortality.
Measurements: We evaluated cross-sectional associations between self-reported educational attainment with the chronic diseases listed using logistic regression models adjusted for demographics, access to care, behaviors, and comorbid conditions. The association of educational attainment with survival was determined using multivariable Cox proportional hazards regression.
Results: Higher educational attainment was associated with a lower prevalence of each of the chronic conditions listed. In multivariable models, compared with persons not completing high school, college graduates had a lower risk of each chronic condition, ranging from 11% lower odds of decreased kidney function to 37% lower odds of cardiovascular disease. During a mean follow-up of 3.9 (median, 3.7) years, 2,384 (4%) deaths occurred. In the fully adjusted Cox model, those who had completed college had 24% lower mortality compared with participants who had completed at least some high school.
Limitations: Lack of income data does not allow us to disentangle the independent effects of education from income.
Conclusions: In this diverse contemporary cohort, higher educational attainment was associated independently with a lower prevalence of chronic diseases and short-term mortality in all age and race/ethnicity groups.

TI Characteristics of Traumatic Cataract Wound Dehiscence

RISK; PHACOEMULSIFICATION; INTERVENTION; COMMUNITY
AB PURPOSE: To characterize the clinical course of cataract wound dehiscence.
DESIGN: Retrospective, comparative case series.
METHODS: Charts of open globe injuries (848 injuries in 846 patients) treated surgically at the Massachusetts Eye and Ear Infirmary between 2000 and 2009 were retrospectively reviewed. Time from original surgery to wound dehiscence, type of initial surgery, Ocular Trauma Score, age, gender, mechanism of injury, and visual acuity were analyzed.
RESULTS: Of 846 patients with 848 open globe injuries, 63 experienced cataract wound dehiscence. The majority of these cataract wounds (89%) were extracapsular cataract extraction (ECCE), with only 7 (11%) phacoemulsification wounds. The mean patient age in the wound rupture group was 78.2 years. Female patients comprised the majority (67%) of this subpopulation. The most common mechanisms of injury were fall (65%), blunt trauma (23%), and motor vehicle accident (7%). The median raw ocular trauma score was 47 in wound dehiscence patients. Visual acuity at presentation was light perception in the wound dehiscence group. The best postoperative visual acuity was significantly worse in the wound dehiscence group (hand motion) than in the remaining patients (20/40; P = .0002). When considering the phacoemulsification patients alone, these patients fared much better, with a median postoperative vision of 20/60.
CONCLUSIONS: Despite recent advances in cataract surgery, wound dehiscence remains a significant source of visual disability, mainly in the geriatric population. Rupture ECCE wound patients have a poor visual prognosis. Fortunately, patients with phacoemulsification site dehiscence appear to regain the majority of their vision after open globe repair (Am J Ophthalmol 2011;152: 229-233. (C) 2011 by Elsevier Inc.

AB Mechanisms of left ventricular (LV) dysfunction in isolated mitral regurgitation (MR) are not well understood. Vasodilator therapy in other forms of LV dysfunction reduces LV wall stress and improves LV function; however, studies in isolated MR show no beneficial effect on LV remodeling using vasodilator drugs or renin-angiotensin system blockade. Therefore, the search for new therapies that improve LV remodeling and function in isolated MR is clinically significant. Recent work in the authors' laboratory has demonstrated increased oxidants from a number of sources including the enzyme xanthine oxidase (XO) in the LV of patients with isolated MR. In addition to being a major source of reactive oxygen species, XO is linked to bioenergetic dysfunction because its substrates derive from adenosine triphosphate catabolism. Correspondingly, there was also evidence of aggregates of small mitochondria in cardiomyocytes, which is generally considered a response to bioenergetic deficit in cells. Future studies are required to determine whether XO and persistent oxidative stress are causative in maladaptive LV remodeling and offer potential therapeutic targets in ameliorating LV damage in patients with isolated MR.

AB In 2003, the US kidney allocation system was changed to eliminate priority for HLA-B similarity. We report outcomes from before and after this change using data from the Scientific Registry of Transplant Recipients (SRTR). Analyses were based on 108 701 solitary deceased donor kidney recipients during the 6 years before and after the policy change. Racial/ethnic distributions of recipients in the two periods were compared (chi-square); graft failures were analyzed using Cox models. In the 6 years before and after the policy change, the overall number of deceased donor transplants rose 23%, with a larger increase for minorities (40%) and a smaller increase for non-Hispanic whites (whites) (8%). The increase in the proportion of transplants for non-whites versus whites was highly significant (p < 0.0001). Two-year graft survival improved for all racial/ethnic groups after implementation of this new policy. Findings confirmed prior SRTR predictions. Following elimination of allocation priority for HLA-B similarity, the deficit in transplantation rates among minorities compared with that for whites was reduced but not eliminated; furthermore, there was no adverse effect on graft survival.

AB Background: The varying nature of chronic pain (CP) is difficult to correlate to neural activity using typical functional magnetic resonance imaging methods. Arterial spin labeling is a perfusion-based imaging technique allowing the absolute quantification of regional cerebral blood flow, which is a surrogate measure of neuronal activity.
Methods: Subjects with chronic low back and radicular pain and matched healthy normal subjects, undergoing identical procedures, participated in three sessions: a characterization and training session and two arterial spin labeling sessions. In the first imaging session, CP (if any) was exacerbated using clinical maneuvers; in the second session, noxious heat was applied to the affected leg dermatome, the intensity of which was matched to the pain intensity level of the CP exacerbations for each back pain subject.
Results: The clinically significant worsening of ongoing CP (<= 30%, n = 16) was associated with significant regional blood flow increases (6-10 mm/100 g of tissue/min, P less than 0.01) within brain regions known to activate with experimental pain (somatosensory, prefrontal, and insular cortices) and in other structures observed less frequently in experimental pain studies, such as the superior parietal lobule (part of the dorsal attention network). This effect is specific to changes in ongoing CP as it is observed during worsening CP, but it is not observed after thermal pain application, or in matched, pain-free healthy controls.
Conclusions: Study findings demonstrate the use of arterial spin labeling to investigate the neural processing of CP, and these findings are a step forward in the quest for objective biomarkers of the chronic pain experience.

AB We recently reported that the endogenous ATP-binding cassette transporter (ABC) A7 strongly associates with phagocytosis, being regulated by sterol regulatory element binding protein 2. We therefore examined the effect of statins on phagocytosis in vitro and in vivo through the SREBP-ABCA7. Phagocytosis was found to be enhanced by pravastatin, rosuvastatin and simvastatin and cyclodextrin in J774 macrophages, as cellular cholesterol was reduced and expressions of the cholesterol-related genes were modulated, including an increase of ABCA7 mRNA and decrease of ABCA1 mRNA. Conversely, knockdown of ABCA7 expression by siRNA ablated enhancement of phagocytosis by statins. In vivo, pravastatin enhanced phagocytosis in wild-type mice, but not in ABCA7-knockout mice. We thus concluded that statins enhance phagocytosis through the SREBP-ABCA7 pathway. These findings provide a molecular basis for enhancement of the host-defense system by statins showing that one of their "pleiotropic" effects is in fact achieved through their reaction to a primary target.

AB Objective: Endothelial function and carotid intima media thickness (cIMT) were investigated in a cohort of 54 healthy adults without known cardiovascular disease.
Methods: Pulse wave amplitude was determined with peripheral arterial tonometry (PAT) to obtain the reactive hyperemia (RH)-PAT ratio. Ultrasound was used to determine cIMT.
Results: cIMT and RH-PAT were significantly associated (rho = -0.35, P = 0.02) in univariate analysis. RH-PAT was significantly associated with age, triglycerides, fasting glucose, HDL, WHR, waist circumference and VAT. cIMT was associated with age, smoking history, fasting glucose, systolic blood pressure, diastolic blood pressure and LDL. In multivariate regression analyses, triglyceride level (P = 0.04) remained a significant determinant of RH-PAT whereas systolic blood pressure (P = 0.02) and smoking pack-year history (P = 0.046) were significant determinants of cIMT.
Conclusion: Determinants of cIMT and RH-PAT were different, dominated by triglyceride and abdominal adiposity measures for RH-PAT but traditional risk factors including blood pressure, glucose, smoking and LDL for cIMT. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

AB Objective: Leptin is an adipokine with both protective and harmful effects on the cardiovascular (CV) system. Prior studies evaluating the association between leptin and CV outcomes have yielded conflicting results. Thus, we sought to investigate the relationship between leptin and CV events and mortality in patients with chronic stable coronary artery disease (CAD).
Methods: We performed a prospective cohort study of 981 outpatients with stable CAD. Leptin levels were measured in fasting venous samples at baseline. We used proportional hazards models to evaluate the association of baseline leptin with subsequent CV events (myocardial infarction, stroke, transient ischemic attack) and death.
Results: During a mean follow-up of 6.2 +/- 2.1 years, there were 304 deaths, 112 myocardial infarctions, and 52 strokes/TIAs. In models adjusted for age, sex, and race, low leptin was associated with a 30% increased risk of the combined outcome (HR 1.30, CI 1.05-1.59, p = 0.01). After further adjustment for obesity, traditional CV risk factors and biomarkers, low leptin remained associated with a 37% increased risk of events (HR 1.37, CI 1.06-1.76, p = 0.02).
Conclusions: Low leptin is associated with increased CV events and mortality in patients with stable coronary artery disease. This association is independent of known factors affecting leptin levels, including gender and obesity. (C) 2010 Elsevier Ireland Ltd. All rights reserved.

AB Angiogenesis inhibition has emerged as a potentially promising treatment strategy for neuroendocrine tumors. 2-Methoxyestradiol (2ME2; Panzem(A (R))) is a natural derivative of estradiol with demonstrated anti-angiogenic activity in animal models. We performed a prospective, phase II study of 2ME2, administered in combination with bevacizumab, in patients with advanced carcinoid tumors.
Thirty-one patients with advanced carcinoid tumors were treated with 2ME2, administered orally at a dose of 1,000 mg four times daily. Patients also received bevacizumab 5 mg/kg intravenously every 2 weeks. Patients were observed for evidence of toxicity, tumor response, and survival.
The combination of 2ME2 and bevacizumab was relatively easily tolerated and was associated with anticipated toxicities for these two agents. No confirmed radiologic responses (by RECIST) were observed. However, 68% of the radiologically evaluable patients experienced at least some degree of tumor reduction, and the median progression-free survival (PFS) time was 11.3 months.
2ME2 and bevacizumab can be safely administered to patients with advanced carcinoid tumors. While major tumor regression was not observed with this regimen, the encouraging median progression-free survival time suggests that this regimen has some degree of antitumor activity and supports the further investigation of angiogenesis inhibitors in this disease.

AB Tumor relapses remain a serious problem after allogeneic stem cell transplantation (alloSCT), despite the long-term persistence of minor histocompatibility antigen (MiHA)-specific memory CD8(+) T cells specific for the tumor. We hypothesized that these memory T cells may lose their function over time in transplanted patients. Here, we offer functional and mechanistic support for this hypothesis, based on immune inhibition by programmed death-1 (PD-1) expressed on MiHA-specific CD8(+) T cells and the associated role of the PD-1 ligand PD-L1 on myeloid leukemia cells, especially under inflammatory conditions. PD-L1 was highly upregulated on immature human leukemic progenitor cells, whereas costimulatory molecules such as CD80 and CD86 were not expressed. Thus, immature leukemic progenitor cells seemed to evade the immune system by inhibiting T-cell function via the PD-1/PD-L1 pathway. Blocking PD-1 signaling using human antibodies led to elevated proliferation and IFN-gamma production of MiHA-specific T cells cocultured with PD-L1-expressing leukemia cells. Moreover, patients with relapsed leukemia after initial MiHA-specific T-cell responses displayed high PD-L1 expression on CD34(+) leukemia cells and increased PD-1 levels on MiHA-specific CD8(+) T cells. Importantly, blocking PD-1/PD-L1 interactions augment proliferation of MiHA-specific CD8(+) memory T cells from relapsed patients. Taken together, our findings indicate that the PD-1/PD-L pathway can be hijacked as an immune escape mechanism in hematological malignancies. Furthermore, they suggest that blocking the PD-1 immune checkpoint offers an appealing immunotherapeutic strategy following alloSCT in patients with recurrent or relapsed disease.

AB Identification and reversal of treatment resistance mechanisms of clinically refractory tumor cells is critical for successful cancer therapy. Here we show that ATP-binding cassette member B5 (ABCB5) identifies therapy-refractory tumor cells in colorectal cancer patients following fluorouracil (5-FU)-based chemoradiation therapy and provide evidence for a functional role of ABCB5 in colorectal cancer 5-FU resistance. Examination of human colon and colorectal cancer specimens revealed ABCB5 to be expressed only on rare cells within healthy intestinal tissue, whereas clinical colorectal cancers exhibited substantially increased levels of ABCB5 expression. Analysis of successive, patient-matched biopsy specimens obtained prior to and following neoadjuvant 5-FU-based chemoradiation therapy in a series of colorectal cancer patients revealed markedly enhanced abundance of ABCB5-positive tumor cells when residual disease was detected. Consistent with this finding, the ABCB5-expressing tumor cell population was also treatment refractory and exhibited resistance to 5-FU-induced apoptosis in a colorectal cancer xenograft model of 5-FU monotherapy. Mechanistically, short hairpin RNA-mediated ABCB5 knockdown significantly inhibited tumorigenic xenograft growth and sensitized colorectal cancer cells to 5-FU-induced cell killing. Our results identify ABCB5 as a novel molecular marker of therapy-refractory tumor cells in colorectal cancer patients and point to a need for consistent eradication of ABCB5-positive resistant tumor cell populations for more effective colorectal cancer therapy.

AB The discovery of BRAF and KIT mutations provided the first basis for a molecular classification of cutaneous melanoma on therapeutic grounds. As BRAF-targeted therapy quickly moves toward regulatory approval and incorporation as standard therapy for patients with metastatic disease, proof of concept has also been established for targeting mutated KIT in melanoma. NRAS mutations have long been known to be present in a subset of melanomas and represent an elusive subgroup for targeted therapies. Matching patient subgroups defined by genetic aberrations in the phosphoinositide 3-kinase and p16/cyclin dependent kinase 4 (CDK4) pathways with appropriate targeted therapies has not yet been realized. And, an increasing understanding of lineage-specific transcriptional regulators, most notably MITF, and how they may play a role in melanoma pathophysiology, has provided another axis to approach with therapies. The foundation has been established for individual oncogene targeting, and current investigations seek to understand the intersection of these susceptibilities and other described potential targets and pathways. The melanoma field stands poised to take the lead among cancer subtypes in advancing combination therapy strategies that simultaneously target multiple biologic underpinnings of the disease.

Patients received sunitinib once daily for 28 days followed by a 14-day break between each cycle. Dose levels of 15 and 20 mg/m(2)/d were evaluated, with dose escalation based on a 3 + 3 design. Sunitinib pharmacokinetics and biomarkers of angiogenesis were also evaluated during the first cycle.
Results: Twenty-three patients were treated (median age 13.9 years; range, 3.9-20.6 years). The most common toxicities were neutropenia, thrombocytopenia, elevated liver transaminases, gastrointestinal symptoms, and fatigue. Two patients developed dose-limiting reductions in cardiac ejection fraction prompting a protocol amendment to exclude patients with previous exposure to anthracyclines or cardiac radiation. In patients without these cardiac risk factors, the maximum tolerated dose (MTD) was 15 mg/m(2)/d. Steady-state plasma concentrations were reached by day 7. No objective responses were observed. Four patients with sarcoma and glioma had stable disease for 2 to 9 cycles.
Conclusions: Cardiac toxicity precluded determination of a recommended dose for pediatric patients with previous anthracycline or cardiac radiation exposure. The MTD of sunitinib for patients without risk factors for cardiac toxicity is 15 mg/m(2)/d for 28 days followed by a 14-day break. Clin Cancer Res; 17(15); 5113-22. (C)2011 AACR.

AB Purpose: p53 as a prognostic and predictive factor in early-stage breast cancer has had mixed results. We studied p53 protein expression, by immunohistochemistry, in a randomized clinical trial of stage II patients treated with adjuvant doxorubicin and cyclophosphamide with or without paclitaxel [Cancer and Leukemia Group B (CALGB) 9344, INT0148].
Patients and Methods: Epithelial p53 expression was evaluated using two immunohistochemical antibodies (DO7 and 1801) in formalin-fixed, paraffin-embedded tissue from patients with node-positive breast cancer who were randomized to four cycles of cyclophosphamide and one of three doses of doxorubicin (60, 75, or 90 mg/m(2); AC) and to receive four subsequent cycles of paclitaxel (T) or not. Prognostic and predictive value of p53 protein expression was assessed, independent of treatment assignment, for escalating doses of doxorubicin or addition of T with endpoints of relapse-free (RFS) and overall survival (OS).
Results: Of 3,121 patients, 1,887 patient specimens treated on C9344 were obtained, passed quality control, and evaluated for p53 expression. Expression was 23% and 27% for mAbs 1801 and D07, respectively, with 92% concordance. In univariate analysis, p53 positivity was associated with worse OS with either antibody, but only p53 staining with monoclonal antibody 1801 had significantly worse RFS. In multivariate analysis, p53 was not predictive of RFS or OS from either doxorubicin dose escalation or addition of paclitaxel regardless of the antibody.
Conclusion: Nuclear staining of p53 by immunohistochemistry is associated with worse prognosis in node-positive patients treated with adjuvant doxorubicin-based chemotherapy but is not a useful predictor of benefit from doxorubicin dose escalation or the addition of paclitaxel.

AB PURPOSE: Copeptin, a stable peptide derived from the AVP precursor, has been linked to presence and severity of myocardial ischemia. We sought to evaluate the predictive value of copeptin and its incremental value beyond that of high-sensitivity cardiac troponin T (hs-cTnT) in patients with acute chest pain and low to intermediate risk for acute coronary syndrome (ACS).
METHODS: We recruited patients who presented with acute chest pain to the emergency department and had a negative initial conventional troponin T test (<0.03 mu g/L). In all patients, hs-cTnT and copeptin measurements were taken. Each patient also underwent cardiac computed tomography (CT) and coronary angiography.
RESULTS: Baseline copeptin concentrations, in contrast to hs-cTnT, were not significantly higher in patients with ACS than in those without (P = 0.24). hs-cTnT showed an earlier rise in patients with ACS than copeptin, when analyses were stratified by time. A copeptin concentration >= 7.38 pmol/L had a negative predictive value (NPV) of 94% and a sensitivity of 51%, whereas hs-cTnT (>= 13.0 pg/mL) had a NPV of 96% and a sensitivity of 63%. The combination of copeptin and hs-cTnT resulted in a lower diagnostic accuracy than hs-cTnT alone. Finally, on cardiac CT, copeptin concentrations were not associated with coronary artery morphology, although they were related to the presence of left ventricular dysfunction (P = 0.02).
CONCLUSIONS: Among patients with acute chest pain and low to intermediate risk for ACS, copeptin concentrations are not independently predictive of ACS and do not add diagnostic value beyond that of hs-cTnT measurements. (C) 2011 American Association for Clinical Chemistry

AB Sickle cell disease (SCD) causes widely disseminated vaso-occlusive episodes. Building on evidence implicating invariant NKT (iNKT) cells in the pathogenesis of ischemia/reperfusion injury, recent studies demonstrate that blockade of iNKT cell activation in mice with SCD reduces pulmonary inflammation and injury. In patients with SCD, iNKT cells in blood are increased in absolute number and activated in comparison to healthy controls. iNKT cell activation is reduced by agonists of adenosine 2A receptors (A(2A)Rs) such as the clinically approved coronary vasodilator, regadenoson. An ongoing multi-center, dose-finding and safety trial of infused regadenoson, has been initiated and is providing preliminary data about its safety and efficacy to treat SCD. Very high accumulation of adenosine may have deleterious effects in SCD through activation of adenosine 2B receptors that are insensitive to regadenoson. Future possible therapeutic approaches for treating SCD include selective A(2B)R antagonists and antibodies that deplete iNKT cells. (C) 2011 Elsevier Inc. All rights reserved.

AB Background Pegylated interferon (PEGIFN) and ribavirin combination is the standard of care for the treatment of chronic hepatitis C virus (HCV) infection. Studies comparing the efficacy and safety of PEGIFN alfa-2a and PEGIFN alfa-2b in treatment-na < ve HCV-infected patients have shown conflicting results.
Aim We performed a systematic review and meta-analysis of studies comparing the efficacy and safety of PEGIFN alfa-2a and PEGIFN alfa-2b in HCV-infected patients na < ve to treatment.
Methods Nine studies (five abstracts) with 3,546 patients (1,771 treated with PEGIFN alfa-2a) comparing PEGIFN alfa-2a and PEGIFN alfa-2b in treatment-na < ve HCV patients were analyzed. Efficacy outcomes were sustained virologic response (SVR) and treatment discontinuation rates due to serious adverse effects (SAE).
Results Pooled data on outcomes (reported as odds ratios [ORs] with 95% confidence intervals [CIs]: [OR (95% CI)]) showed higher SVR in patients treated with PEGIFN alfa-2a as compared to treatment with PEGIFN alfa-2b [1.36 (1.07-1.73); P = 0.01]. Subgroup analysis of good quality studies on SVR in genotypes 2 and 3 also favored PEGIFN alfa-2a over PEGIFN alfa-2b (1.91 [1.09-3.37]; P = 0.02). SVR results obtained with the two types of IFN showed no impact of viral load and the presence or absence of cirrhosis. Treatment discontinuation rates due to SAE, reported in six studies (two abstracts) on 3,211 patients (1,604 treated with PEGIFN alfa-2a), were similar in the two types of PEGIFN [0.66 (0.37-1.16); P = 0.15].
Conclusions PEGIFN alfa-2a has superior efficacy with higher SVR as compared to PEGIFN alfa-2b in treatment-na < ve HCV-infected patients. The safety profile of the two types of PEGIFN was similar.

PATHOGENESIS
AB Background Hepatic encephalopathy is a syndrome whose physiopathology is poorly understood; therefore, current diagnostic tests are imperfect and modern therapy is nonspecific. Particularly, it has been suggested that inflammation plays an important role in the pathogenesis of portal hypertensive encephalopathy in the rat.
Aim We have studied an experimental model of portal hypertension based on a triple partial portal vein ligation in the rat to verify this hypothesis.
Methods One month after portal hypertension we assayed in the splanchnic area (liver, small bowel and mesenteric lymph nodes) and in the central nervous system (hippocampus and cerebellum) fractalkine (CX3CL1) and stromal cell-derived factor alpha (SDF1-alpha) as well as their respective receptors (CX3CR1 and CXCR4) because of their key role in inflammatory processes.
Results The significant increase of fractalkine in mesenteric lymph nodes (P < 0.05) and its receptor (CX3CR1) in the small bowel (P < 0.05) and hippocampus (P < 0.01), associated with the increased expression of SDF1-alpha in the hippocampus (P < 0.01) and the cerebellum (P < 0.01) suggest that prehepatic portal hypertension in the rat induces important alterations in the expression of chemokines in the gut-brain axis.
Conclusion The present study revealed that portal hypertension is associated with splanchnic-brain inflammatory alterations mediated by chemokines.

AB The objective of the study was to evaluate whether mental health problems identified through screens administered in first grade are related to poorer academic achievement test scores in the fourth grade. The government of Chile uses brief teacher- and parent-completed measures [Teacher Observation of Classroom Adaptation-Revised (TOCA-RR) and Pediatric Symptom Checklist (PSC-Cl)] to screen for mental health problems in about one-fifth of the country's elementary schools. In fourth grade, students take the national achievement tests (SIMCE) of language, mathematics and science. This study examined whether mental health problems identified through either or both screens predicted achievement test scores after controlling for student and family risk factors. A total of 17,252 students had complete first grade teacher forms and these were matched with fourth grade SIMCE data for 11,185 students, 7,903 of whom also had complete parent form data from the first grade. Students at risk on either the TOCA-RR or the PSC-Cl or both performed significantly worse on all SIMCE subtests. Even after controlling for covariates and adjusting for missing data, students with mental health problems on one screen in first grade had fourth grade achievement scores that were 14-18 points (similar to 1/3 SD) lower than students screened as not at risk. Students at risk on both screens had scores that were on average 33 points lower than students at risk on either screen. Mental health problems in first grade were one of the strongest predictors of lower achievement test scores 3 years later, supporting the premise that for children mental health matters in the real world.

AB Regulatory T cells (Tregs) migrate into peripheral sites of inflammation such as allografts undergoing rejection, where they serve to suppress the immune response. In this study, we find that similar to 30-40% of human CD25(hi) FOXP3(+) CD4(+) Tregs express the peripheral CXC chemokine receptor 3 (CXCR3) and that this subset has potent immunoregulatory properties. Consistently, we observed that proliferative responses as well as IFN-gamma production were significantly higher using CXCR3-depleted versus undepleted responders in the mixed lymphocyte reaction, as well as following mitogen-dependent activation of T cells. Using microfluidics, we also found that CXCR3 was functional on CXCR3(pos) Tregs, in as much as chemotaxis and directional persistence towards interferon-gamma-inducible protein of 10kDa (IP-10) was significantly greater for CXCR3(pos) than CXCR3(neg) Tregs. Following activation, CXCR3-expressing CD4(+) Tregs were maintained in vitro in cell culture in the presence of the mammalian target of rapamycin (mTOR) inhibitor rapamycin, and we detected higher numbers of circulating CXCR3(+) FOXP3(+) T cells in adult and pediatric recipients of renal transplants who were treated with mTOR-inhibitor immunosuppressive therapy. Collectively, these results demonstrate that the peripheral homing receptor CXCR3 is expressed on subset(s) of circulating human Tregs and suggest a role for CXCR3 in their recruitment into peripheral sites of inflammation.

AB Antibody diversity is generated by a random gene recombination process with the inherent risk of the production of autoreactive specificities. The current view suggests that B cells expressing such specificities are negatively selected at an early developmental stage. Using the knock-in model system of the 3-83 autoreactive B-cell antigen receptor (BCR) in combination with precursor-BCR (pre-BCR) deficiency, we show here that the 3-83 BCR mediates efficient generation of B cells in the presence, but not the absence, of a strongly recognized auto-antigen. Experiments with mixed bone marrow chimeras showed that combining the 3-83 BCR with the corresponding auto-antigen resulted in efficient reconstitution of B-cell development in immune-deficient mice. These results suggest that B cells are positively selected by recognition of self-antigens during developmental stages that precede receptor editing. Moreover, the data indicate that the pre-BCR functions as a specialized autoreactive BCR to initiate positive selection at a stage where the cells express immunoglobulin heavy but not light chains.

AB Improving patient-clinician communication about end-of-life care is important in order to enhance quality of care for patients with chronic obstructive pulmonary disease (COPD). Our objective was to compare quality of patient-clinician communication about end-of-life care, and endorsement of barriers and facilitators to this communication in the Netherlands and the USA.
The present study was an analysis of survey data from 122 Dutch and 391 US outpatients with COPD. We compared quality of patient-clinician communication about end-of-life care (Quality of Communication questionnaire) and barriers and facilitators to communication about end-of-life care (Barriers and Facilitators Questionnaire) between the Netherlands and the USA, controlling for patients' demographic and illness characteristics.
Although Dutch patients in this study had worse lung function and disease-specific health status than US patients, Dutch patients reported lower quality of communication about end-of-life care (median score 0.0 (interquartile range 0.0-2.0) versus 1.4 (0.0-3.6); adjusted p < 0.005). Clinicians in both countries rarely discussed life-sustaining treatment preferences, prognoses, dying processes or spiritual issues.
Quality of communication about end-of-life care needs to improve in the Netherlands and the USA. Future studies to improve this communication should be designed to take into account international differences and patient-specific barriers and facilitators to communication about end-of-life care.

AB Background: Diabetic foot ulceration has a complex and multifactorial etiology and can involve changes in the pathophysiology of the plantar soft tissue. In the current study, histomorphological analyses of diabetic and non-diabetic plantar tissue were performed. It was hypothesized that the diabetic tissue would have thicker skin (epidermis and dermis), less interdigitation between the dermis and epidermis, thicker elastic septa and decreased adipose cell size. Materials and Methods: Two locations of the foot (the heel and the first metatarsal) were examined, both of which have been reported to be locations with a high incidence of ulceration. Stereo logical methods and quantitative morphological techniques were used to evaluate the skin thickness, interdigitation index, elastic septae thickness and adipocyte cell size. Results: The diabetic donors had a greater body mass index (BMI) than the non-diabetic donors. The diabetic tissue had significantly thicker elastic septae and dermis. However, no significant difference was observed in the interdigitation index or adipocyte size. Conclusion: These findings demonstrate that morphological changes can be evaluated histologically to give a better understanding of the pathological changes in the plantar soft tissue with diabetes. These evaluations can then be associated with biomechanical changes that occur in diabetes to provide new insight into how microstructural changes can alter macroscopic properties. Clinical Relevance: An understanding of the histomorphological changes in the soft tissue in relationship to the location on the foot could help to explain the biomechanical changes that occur in diabetes and the subsequent increase in susceptibility to breakdown.

AB This paper examines the views of Hong Kong community leaders on the underlying issues that affect family health, happiness and harmony (3Hs) in Hong Kong. Using a community reconnaissance method, a series of individual in-depth interviews with 26 leaders that represent neighbourhoods of diverse socio-economic status (SES) from June to August 2008 were conducted. Participants considered that changing family structure, economic situation and strong work ethic are the most salient factors that affect family 3Hs. The deprived comprehensive social security assistance recipients, single-parent families and migrant women were considered to be the most vulnerable groups to breakdown in family 3Hs and particularly, they lack family resources. Families from different SES have to overcome different challenges in order to achieve and sustain family 3Hs. Leaders from low SES neighbourhood were concerned more about providing tangible help such as child care facilities to improve family resources, whereas leaders from high SES neighbourhood focused more on preventive interventions such as education on relationship skills to achieve better family well-being. The findings offer insights in designing effective social marketing education campaigns and family-friendly workplace policy to promote social harmony through the maintenance of 3Hs families.

AB The incidence of liver disease progression among subjects with histologically advanced but compensated chronic hepatitis C is incomplete. The Hepatitis C Antiviral Long-term Treatment against Cirrhosis Trial was a randomized study of 3.5 years of maintenance peginterferon treatment on liver disease progression among patients who had not cleared virus on peginterferon and ribavirin therapy. Patients were followed subsequently off therapy. Because maintenance peginterferon treatment did not alter liver disease progression, we analyzed treated and control patients together. Among 1,050 subjects (60% advanced fibrosis, 40% cirrhosis), we determined the rate of progression to cirrhosis over 4 years and of clinical outcomes over 8 years. Among patients with fibrosis, the incidence of cirrhosis was 9.9% per year. Six hundred seventy-nine clinical outcomes occurred among 329 subjects. Initial clinical outcomes occurred more frequently among subjects with cirrhosis (7.5% per year) than subjects with fibrosis (3.3% per year) (P < 0.0001). Child-Turcotte-Pugh (CTP) score >= 7 was the most common first outcome, followed by hepatocellular carcinoma. Following occurrence of a CTP score >= 7, the rate of subsequent events increased to 12.9% per year, including a death rate of 10% per year. Age and sex did not influence outcome rates. Baseline platelet count was a strong predictor of all clinical outcomes. During the 8 years of follow-up, death or liver transplantation occurred among 12.2% of patients with advanced fibrosis and 31.5% of those with cirrhosis. Conclusion: Among patients with advanced hepatitis C who failed peginterferon and ribavirin therapy, the rate of liver-related outcomes, including death and liver transplantation, is high, especially once the CTP score reaches at least 7.

TI Lack of De Novo Phosphatidylinositol Synthesis Leads to Endoplasmic
Reticulum Stress and Hepatic Steatosis in cdipt-Deficient Zebrafish
SO HEPATOLOGY

DT Article
ID FATTY LIVER-DISEASE; GENE-EXPRESSION; ER STRESS; CANCER; RESPONSES;
LIPIDS
AB Hepatic steatosis is the initial stage of nonalcoholic fatty liver disease (NAFLD) and may predispose to more severe hepatic disease, including hepatocellular carcinoma. Endoplasmic reticulum (ER) stress has been recently implicated as a novel mechanism that may lead to NAFLD, although the genetic factors invoking ER stress are largely unknown. During a screen for liver defects from a zebrafish insertional mutant library, we isolated the mutant cdipt(hi559Tg-/+) (hi559). CDIPT is known to play an indispensable role in phosphatidylinositol (PtdIns) synthesis. Here we show that cdipt is expressed in the developing liver, and its disruption in hi559 mutants abrogates de novo PtdIns synthesis, resulting in hepatomegaly at 5 days postfertilization. The hi559 hepatocytes display features of NAFLD, including macrovesicular steatosis, ballooning, and necroapoptosis. Gene set enrichment of microarray profiling revealed significant enrichment of endoplasmic reticulum stress response (ERSR) genes in hi559 mutants. ER stress markers, including atf6, hspa5, calr, and xbp1, are selectively up-regulated in the mutant liver. The hi559 expression profile showed significant overlap with that of mammalian hepatic ER stress and NAFLD. Ultrastructurally, the hi559 hepatocytes display marked disruption of ER architecture with hallmarks of chronic unresolved ER stress. Induction of ER stress by tunicamycin in wild-type larvae results in a fatty liver similar to hi559, suggesting that ER stress could be a fundamental mechanism contributing to hepatic steatosis. Conclusion: cdipt-deficient zebrafish exhibit hepatic ER stress and NAFLD pathologies, implicating a novel link between PtdIns, ER stress, and steatosis. The tractability of hi559 mutant provides a valuable tool to dissect ERSR components, their contribution to molecular pathogenesis, and evaluation of novel therapeutics of NAFLD.

AB Because hyperhomocysteinemia can occur in cholesterol gallstone disease, we hypothesized that this may result from trimethylation of phosphatidylethanolamine (PE), which partakes in biliary phosphatidylcholine (PC) hypersecretion during cholesterol cholelithogenesis. We fed murine strains C57L/J, C57BL/6J, SWR/J, AKR/J, PE N-methyltransferase (PEMT) knockout (KO), PEMT heterozygous (HET), and wildtype (WT) mice a cholesterol/cholic acid lithogenic diet (LD) for up to 56 days and documented biliary lipid phase transitions and secretion rates. We quantified plasma total homocysteine (tHcy), folate, and vitamin B(12) in plasma and liver, as well as biliary tHcy and cysteine secretion rates. Rate-limiting enzyme activities of PC synthesis, PEMT and cytidine triphosphate: phosphocholine cytidylyltransferase (PCT), S-adenosylmethionine (SAM), and S-adenosylhomocysteine (SAH) were measured in liver homogenates. Other potential sources of plasma tHcy, glycine N-methyltransferase (GNMT) and guanidinoacetate N-methyltransferase (GAMT), were assayed by gene expression. Plasma tHcy and PEMT activities became elevated during cholelithogenesis in gallstone-susceptible C57L, C57BL/6, and SWR mice but not in the gallstone-resistant AKR mice. Persisting in C57L mice, which exhibit the greatest Lith gene burden, these increases were accompanied by elevated hepatic SAM/SAH ratios and augmented biliary tHcy secretion rates. Counter-regulation included remethylation of Hcy to methionine concurrent with decreased folate and vitamin B(12) levels and Hcy transsulfuration to cysteine. Concomitantly, methylenetetrahydrofolate reductase (Mthfr), betaine-homocysteine methyltransferase (Bhmt), and cystathionine-beta-synthase (Cbs) were up-regulated, but Gnmt and Gamt genes were down-regulated. PEMT KO and HET mice displayed biliary lipid secretion rates and high gallstone prevalence rates similar to WT mice without any elevation in plasma tHcy levels. Conclusion: This work implicates up-regulation of PC synthesis by the PEMT pathway as a source of elevated plasma and bile tHcy during cholesterol cholelithogenesis. (HEPATOLOGY 2011;54:697-706)

AB A significant finding with aging humans (and aging animal models) is that blood vessels lose their ability to respond to beta-adrenergic receptor stimuli. Therefore, they produce less cyclic adenosine monophosphate (cAMP) and have decreased vasorelaxation with advancing age. This change likely contributes to hypertension, insufficient blood flow, and atherosclerosis. Our goal was to develop a vascular smooth muscle cell culture model that replicates the molecular and biochemical changes observed in blood vessels with advancing age. A clonal selection strategy was used to produce cell lines from 2-, 6-, 12-, and 24-month-old male Fischer 344 rat aortae. Cultures were validated as smooth muscle cells with immunocytochemistry positive for alpha-actin and negative for von Willebrand factor VIII. Positive staining for G protein-coupled receptor kinase 2 indicated presence of this adrenergic receptor regulator. A total of n = 5 clones from n = 7 animals for each age group were initially analyzed for cAMP accumulation under three conditions: basal, isoproterenol stimulated, and forskolin stimulated. Results found that at passage 3, there was a significant reduction in cAMP accumulation to isoproterenol. However, this reduction disappeared by passage 6. Secondary analysis segregated clones into phenotypic age groups independent of donor animal age. Segregation identified n = 3 clones per group. At passage 3, the age-related change in the beta-adrenergic change was magnified. However, even with segregation, the adrenergic response was lost by passage 6. Our results show that early passaged clonal vascular smooth muscle cell cultures maintain their aging, adrenergic phenotype. Two separate strategies to identify age-representative phenotypes into later passage were unsuccessful.

AB Recently described forkhead box protein 3 (FoxP3) transcription factor is a key molecule in CD4+ CD25hi+ T-cell characterization. Invariant NK T (iNKT) cells are also characterized as regulatory cells modulating the immune response by rapidly producing T(h)1 and T(h)2 cytokines. We aimed to analyze cellular markers important in regulatory features of human iNKT cells and to study their role in functional assays. iNKT cells were single cell sorted from peripheral mononuclear cells of healthy individuals after immunostaining of invariant TCR alpha-chain. We found FoxP3 expression in human iNKT clones. Randomly selected iNKT cell clones (CD4+, double negative, CD8+) expressed FoxP3 mRNA and protein at different levels upon stimulation as supported by various approaches. FoxP3 mRNA and protein expression was detected in unstimulated iNKT cells as well. Furthermore, different stimulations changed the FoxP3 expression in iNKT cells over time and the most dramatic changes were observed upon anti-CD3 stimulation. Both the supernatant of iNKT cells and iNKT cells themselves exerted similar stimulation effects on PBMC proliferation in functional assays and these stimulations showed a negative correlation with FoxP3 expression. Our data indicate that the FoxP3 expression in iNKT cells may be a key transcriptional factor in controlling the regulatory function of the iNKT cells.

AB Objective: This study aimed to examine the pattern of recurrence in patients with endometrioid endometrial cancer and to identify clinically important prognostic factors in the recurrent population.
Methods: With institutional review board approval, a retrospective review identified 1061 patients who underwent primary surgery and treatment of endometrioid endometrial cancer at our institution from 1994 to 2007. Of this cohort, 77 (7.2%) patients developed a recurrence. Clinical factors were recorded, and Spearman correlation coefficients and chi(2) test were used to determine associations between groups. Kaplan-Meier survival estimates and Cox proportional-hazards model were used to determine how prognostic variables affected survival after recurrence (RS) and overall survival (OS).
Results: Of 77 patients, site of recurrence was not available in 5 patients. The distribution of recurrence in the remaining 72 patients was as follows: isolated vaginal 18% (13/72), nonvaginal pelvic 12% (9/72), distant 31% (22/72), abdominal 24% (17/72), and nodal 15% (11/72). There was an overrepresentation of advanced stage (P < 0.001) and high-grade (P < 0.003) at presentation in the recurrent group. Median OS was 3.4 years and median RS was 1.3 years. Low-grade tumors, early stage, and those with less than 50% myometrial invasion were associated with a significant OS and RS advantage. Age-adjusted isolated vaginal recurrence presented with a 1.2-year RS survival advantage (P < 0.03). An age-adjusted Cox proportional hazard ratio model incorporating significant prognostic variables demonstrated that the only independent variable associated with worse OS and RS was increased histologic grade with a hazard ratio of 2.31 (95% confidence interval, 1.25Y3.97) for RS and 2.44 (95% confidence interval, 1.41-4.62) for OS.
Conclusions: Those patients with high-grade histology at the time of initial diagnosis manifest a decreased OS and RS, suggesting that the intrinsic biology of the tumor has the greatest prognostic importance.

AB Purpose: Pancreatic cancer primary tumor size measurements are often discordant between computed tomography (CT) and pathologic specimen after resection. Dimensions of the primary tumor are increasingly relevant in an era of highly conformal radiotherapy.
Methods and Materials: We retrospectively evaluated 97 consecutive patients with resected pancreatic cancer at two Boston hospitals. All patients had CT scans before surgical resection. Primary endpoints were maximum dimension (in millimeters) of the primary tumor in any direction as reported by the radiologist on CT and by the pathologist for the resected gross fresh specimen. Endoscopic ultrasound (EUS) findings were analyzed if available.
Results: Of the patients, 87 (90%) had preoperative CT scans available for review and 46 (47%) had EUS. Among proximal tumors (n = 69), 40 (58%) had pathologic duodenal invasion, which was seen on CT in only 3 cases. The pathologic tumor size was a median of 7 mm larger compared with CT size for the same patient (range, 15 to 43 mm; p < 0.0001), with 73 patients (84%) having a primary tumor larger on pathology than CT. Endoscopic ultrasound was somewhat more accurate, with pathologic tumor size being a median of only 5 mm larger compared with EUS size (range, 15 to 35 mm; p = 0.0003).
Conclusions: Computed tomography scans significantly under-represent pancreatic cancer tumor size compared with pathologic specimens in resectable cases. We propose a clinical target volume expansion formula for the primary tumor based on our data. The high rate of pathologic duodenal invasion suggests a risk of duodenal under-coverage with highly conformal radiotherapy. (C) 2011 Elsevier Inc.

AB Purpose: No single standard treatment paradigm is available for head-and-neck squamous cell carcinoma of an unknown primary (HNCUP). Bilateral neck radiotherapy with mucosal axis irradiation is widely used, with or without chemotherapy and/or surgical resection. Intensity-modulated radiotherapy (IMRT) is a highly conformal method for delivering radiation that is becoming the standard of care and might reduce the long-term treatment-related sequelae. We report the Dana-Farber Cancer Institute experience with IMRT-based treatment for HNCUP.
Patients and Materials: A retrospective study of all patients treated at the Dana-Farber Cancer Institute for HNCUP with IMRT between August 2004 and January 2009. The primary endpoint was overall survival; the secondary endpoints were locoregional and distant control, and acute and chronic toxicity.
Results: A total of 24 patients with HNCUP were included. Of these patients, 22 had Stage N2 disease or greater. All patients underwent neck computed tomography, positron emission tomography-computed tomography, and examination under anesthesia with directed biopsies. Of the 24 patients, 22 received concurrent chemotherapy, and 7 (29%) also underwent induction chemotherapy. The median involved nodal dose was 70 Gy, and the median mucosal dose was 60 Gy. With a median follow-up of 2.1 years, the 2-year actuarial overall survival and locoregional control rate was 92% and 100%, respectively. Only 25% of the patients had Grade 2 xerostomia, although 11 patients (46%) required esophageal dilation for stricture.
Conclusion: In a single-institution series, IMRT-based chemoradiotherapy for HNCUP was associated with superb overall survival and locoregional control. The xerostomia rates were promising, but the aggressive therapy was associated with significant rates of esophageal stenosis. (C) 2011 Elsevier Inc.

AB Purpose: To calculate the linear energy transfer (LET) distributions in patients undergoing proton therapy. These distributions can be used to identify areas of elevated or diminished biological effect. The location of such areas might be influenced in intensity-modulated proton therapy (IMPT) optimization.
Methods and Materials: Because Monte Carlo studies to investigate the LET distribution in patients have not been undertaken so far, the code is first validated with simulations in water. The code was used in five patients, for each of them three planning and delivery techniques were simulated: passive scattering, three-dimensional modulation IMPT (3D-IMPT), and distal edge tracking IMPT (DET-IMPT).
Results: The inclusion of secondary particles led to significant differences compared with analytical techniques. In addition, passive scattering and 3D-IMPT led to largely comparable LET distributions, whereas the DET-IMPT plans resulted in considerably increased LET values in normal tissues and critical structures. In the brainstem, dose-averaged LET values exceeding 5 keV/mu m were observed in areas with significant dose (>70% of prescribed dose). In noncritical normal tissues, even values >8 keV/mu m occurred.
Conclusion: This work demonstrates that active scanning offers the possibility of influencing the distribution of dose-averaged LET (i.e., the biological effect) without significantly altering the distribution of physical dose. On the basis of this finding, we propose a method to alter deliberately the LET distribution of a treatment plan in such a manner that the LET is maximized within certain target areas and minimized in normal tissues, while maintaining the prescribed target dose and dose constraints for organs at risk.

AB Background: The role of natural aeroallergen exposure in modulating allergen-specific immune responses is not well understood.
Objective: We sought to examine relationships between mouse allergen exposure and mouse-specific immune responses.
Methods: New employees (n = 179) at a mouse facility underwent repeated assessment of mouse allergen exposure, skin prick tests (SPTs), and measurement of mouse-specific IgG levels. Relationships between the mean level of exposure, variability of exposure (calculated as log deviation), and time to development of immunologic outcomes were examined by using Cox proportional hazards models.
Results: By 24 months, 32 (23%) participants had experienced a positive SPT response, and 10 (8%) had mouse-specific IgG(4). The incidence of a positive SPT response increased as levels of exposure increased from low to moderate, peaking at 1.2 ng/m(3), and decreased beyond this point (P = .04). The more variable the exposure was across visits, the lower the incidence of a positive SPT response (hazard ratio [HR], 0.17; 95% CI, 0.07-0.41). Variability of exposure was an independent predictor of a positive SPT response in a model that included both exposure metrics. In contrast, the incidence of mouse-specific IgG(4) increased with increasing levels of mouse allergen exposure (HR, 2.9; 95% CI, 1.4-6.0), and there was evidence of a higher risk of mouse-specific IgG(4) with greater variability of exposure (HR, 6.3; 95% CI, 0.4-95.2).
Conclusion: Both the level and variability of mouse allergen exposure influence the humoral immune response, with specific patterns of exposure associated with specific immunophenotypes. Exposure variability might be a more important predictor of a positive SPT response, whereas the average exposure level might be a more important predictor of mouse-specific IgG(4).

AB Continuous treatment with parathyroid hormone (PTH) or excess endogenous PTH due to primary hyperparathyroidism causes increased bone resorption and, subsequently, decreased bone volume. Our previous studies showed that myeloid Elf-1-like factor (MEF) not only suppresses osteoblast differentiation through inhibition of Runx2 activity and other osteogenesis-related genes but also specifically increases the expression of Mab21, a potential transcriptional repressor of osteoblast differentiation. Here we show that the JNK1 pathway is involved in the MEF-mediated up-regulation of Mab21 expression due to PTH stimulation. PTH increased the transcription level of Mab21 in MG63 human osteoblastic cells, in contrast to the suppressive effect of TGF beta 1. PTH phosphorylates serine residues of MEF as well as c-Jun, a known substrate of JNK1. By in vitro kinase assay, we confirmed that MEF is phosphorylated by JNK1, but not by ERK. Co-transfection of MEF with both MKK4 and JNK1 increased the promoter activity of Mab21 in CV1 cells significantly more than MEF alone. We also identified the phosphorylation of MEF serine 641 by in vitro and in vivo JNK1 kinase assays combined with a proteomics approach. In conclusion, our findings indicate that MEF is involved in PTH suppression of osteoblasts through activating the MKK4/JNK1 pathway and subsequently up-regulating Mab21 expression. J. Cell.

AB While oral anticoagulants are associated with greater hematoma expansion and higher mortality rates in patients with intracerebral hemorrhage (ICH), there is ongoing discussion whether pretreatment with antiplatelet drugs also worsens prognosis. Using an experimental model of ICH, we investigated the effects of antiplatelet pretreatment on hematoma volume and functional outcome. CD-1 mice were treated with acetyl-salicylic acid (ASA, 60 mg/kg per 24 hours), clopidogrel (22.5 mg/kg per 24 hours), or both (ASA + clopidogrel) through drinking water for 3 days (n = 20 per group). Thereafter, platelet aggregation was found to be significantly reduced. Untreated mice and mice pretreated with warfarin served as controls. A stereotactic injection of collagenase into the right striatum was used to induce ICH. Twenty-four hours after ICH induction, hematoma volume was measured to be 15.0 +/- 4.4 mu L in controls, 14.1 +/- 5.3 mu L in ASA mice, 16.8 +/- 5.1 mu L in clopidogrel mice, and 16.4 +/- 5.1 mu L in ASA + clopidogrel animals. These differences were not statistically significant. However, mice pretreated with warfarin revealed largely increased hematoma volumes (25.0 +/- 7.4 mu L versus controls, P = 0.001). Neurologic outcome was not different between antiplatelet-pretreated animals and untreated controls. Our results suggest that plasmatic coagulation rather than platelet function is the most critical element for preventing hematoma expansion in acute ICH. Future therapeutic strategies may take these findings into account. Journal of Cerebral Blood Flow & Metabolism (2011) 31, 1736-1742; doi:10.1038/jcbfm.2011.22; published online 9 March 2011

AB The ischemic tissue becomes acidic after initiation of anaerobic respiration, which may result in impaired tissue metabolism and, ultimately, in severe tissue damage. Although changes in the major cerebral metabolites can be studied using magnetic resonance (MR) spectroscopy (MRS)-based techniques, their spatiotemporal resolution is often not sufficient for routine examination of fast-evolving and heterogeneous acute stroke lesions. Recently, pH-weighted MR imaging (MRI) has been proposed as a means to assess tissue acidosis by probing the pH-dependent chemical exchange of amide protons from endogenous proteins and peptides. In this study, we characterized acute ischemic tissue damage using localized proton MRS and multiparametric imaging techniques that included perfusion, diffusion, pH, and relaxation MRI. Our study showed that pH-weighted MRI can detect ischemic lesions and strongly correlates with tissue lactate content measured by (1)H MRS, indicating lactic acidosis. Our results also confirmed the correlation between apparent diffusion coefficient and lactate; however, no significant relationship was found for perfusion, T(1), and T(2). In summary, our study showed that optimized endogenous pH-weighted MRI, by sensitizing to local tissue pH, remains a promising tool for providing a surrogate imaging marker of lactic acidosis and altered tissue metabolism, and augments conventional techniques for stroke diagnosis.

TI Collaborative Evaluation of an Erythromycin-Clindamycin Combination Well
for Detection of Inducible Clindamycin Resistance in Beta-Hemolytic
Streptococci by Use of the CLSI Broth Microdilution Method
SO JOURNAL OF CLINICAL MICROBIOLOGY
LA English
DT Article
ID MECHANISMS
AB Constitutive or inducible clindamycin resistance can occur in beta-hemolytic streptococci due to the presence of an erm gene. The Clinical and Laboratory Standards Institute (CLSI) has recommended a disk approximation test (D-zone test) with erythromycin and clindamycin disks and a single-well broth test combining erythromycin and clindamycin for detection of inducible clindamycin resistance in staphylococci, but only a disk approximation test for the beta-hemolytic streptococci. This collaborative study assessed two different erythromycin and clindamycin concentration combinations in single wells (1 mu g/ml + 0.25 mu g/ml [erythromycin plus clindamycin] and 1 mu g/ml + 0.5 mu g/ml) with three different brands of Mueller-Hinton broth supplemented with 3% lysed horse blood for testing of frozen panels prepared for this study. All labs performed the D-zone test as described by the CLSI. A total of 155 nonduplicate streptococcal isolates (50 group A, 48 group B, 28 group C, and 29 group G isolates) were tested; 99 isolates showed inducible resistance by the D-zone test. There were some differences noted based upon the test medium. The sensitivity of the erythromycin plus clindamycin combination of 1 mu g/ml + 0.25 mu g/ml was 91 to 100%, while the sensitivity of the combination of 1 mu g/ml + 0.5 mu g/ml was 95 to 100%. Specificity overall was 98%. The slightly higher sensitivity of the combination of 1 mu g/ml + 0.5 mu g/ml is recommended. This study has demonstrated that a single-well microdilution test incorporating erythromycin and clindamycin in combination is a sensitive and specific indicator of inducible clindamycin resistance and could be included in routine test panels.

AB Purpose
High-dose therapy (HDT) and autologous stem-cell transplantation (ASCT) are frequently used in an attempt to improve outcome in patients with mantle-cell lymphoma (MCL); however, the importance of intensive induction regimens before transplantation is unknown.
Patients and Methods
To address this question, we evaluated baseline characteristics, time to treatment, induction regimen, disease status at the time of transplantation, and MIPI score at diagnosis and their associations with survival in 118 consecutive patients with MCL who received HDT and ASCT at our centers.
Results
The MIPI was independently associated with survival after transplantation in all 118 patients (hazard ratio [HR], 3.5; P < .001) and in the 85 patients who underwent ASCT as initial consolidation (HR, 7.2; P < .001). Overall survival rates were 93%, 60%, and 32% at 2.5 years from ASCT for all patients with low-, intermediate-, and high-risk MIPI, respectively. Low-risk MIPI scores were more common in the intensive induction group than the standard induction group in all patients (64% v 46%, respectively; P = .03) and in the initial consolidation group (66% v 45%, respectively; P = .03). After adjustment for the MIPI, an intensive induction regimen was not associated with improved survival after transplantation in all patients (HR, 0.5; P = .10), the initial consolidation group (HR, 1.1; P = .86), or patients <= 60 years old (HR, 0.6; P = .50). Observation of more than 3 months before initiating therapy did not yield inferior survival (HR, 2.1; P = .12) after adjustment for the MIPI in patients receiving ASCT.
Conclusion
An intensive induction regimen before HDT and ASCT was not associated with improved survival after adjusting for differences in MIPI scores at diagnosis.

SURGERY; PEDICLE; DEFECTS; TUMORS
AB Purpose
Standardized indications for treatment of tumor-related spinal instability are hampered by the lack of a valid and reliable classification system. The objective of this study was to determine the interobserver reliability, intraobserver reliability, and predictive validity of the Spinal Instability Neoplastic Score (SINS).
Methods
Clinical and radiographic data from 30 patients with spinal tumors were classified as stable, potentially unstable, and unstable by members of the Spine Oncology Study Group. The median category for each patient case (consensus opinion) was used as the gold standard for predictive validity testing. On two occasions at least 6 weeks apart, each rater also scored each patient using SINS. Each total score was converted into a three-category data field, with 0 to 6 as stable, 7 to 12 as potentially unstable, and 13 to 18 as unstable.
Results
The kappa statistics for interobserver reliability were 0.790, 0.841, 0.244, 0.456, 0.462, and 0.492 for the fields of location, pain, bone quality, alignment, vertebral body collapse, and posterolateral involvement, respectively. The kappa statistics for intraobserver reliability were 0.806, 0.859, 0.528, 0.614, 0.590, and 0.662 for the same respective fields. Intraclass correlation coefficients for inter-and intraobserver reliability of total SINS score were 0.846 (95% CI, 0.773 to 0.911) and 0.886 (95% CI, 0.868 to 0.902), respectively. The kappa statistic for predictive validity was 0.712 (95% CI, 0.676 to 0.766).
Conclusion
SINS demonstrated near-perfect inter- and intraobserver reliability in determining three clinically relevant categories of stability. The sensitivity and specificity of SINS for potentially unstable or unstable lesions were 95.7% and 79.5%, respectively. J Clin Oncol 29: 3072-3077. (C) 2011 by American Society of Clinical Oncology

AB A detailed understanding of the mechanisms by which tumors acquire resistance to targeted anticancer agents should speed the development of treatment strategies with lasting clinical efficacy. RAF inhibition in BRAF-mutant melanoma exemplifies the promise and challenge of many targeted drugs; although response rates are high, resistance invariably develops. Here, we articulate overarching principles of resistance to kinase inhibitors, as well as a translational approach to characterize resistance in the clinical setting through tumor mutation profiling. As a proof of principle, we performed targeted, massively parallel sequencing of 138 cancer genes in a tumor obtained from a patient with melanoma who developed resistance to PLX4032 after an initial dramatic response. The resulting profile identified an activating mutation at codon 121 in the downstream kinase MEK1 that was absent in the corresponding pretreatment tumor. The MEK1(C121S) mutation was shown to increase kinase activity and confer robust resistance to both RAF and MEK inhibition in vitro. Thus, MEK1(C121S) or functionally similar mutations are predicted to confer resistance to combined MEK/RAF inhibition.

AB Rationale, aims and objectives Efforts to implement evidence-based medicine (EBM) training in developing countries are limited. We describe the results of an international effort to improve research capacity in a developing country; we conducted a course aimed at improving basic EBM attitudes and identified challenges.
Method Between 2005 and 2009, we conducted an annual 3-day course in Peru consisting of interactive lectures and case-based workshops. We assessed self-reported competence and importance in EBM using a Likert scale (1 = low, 5 = high).
Results Totally 220 clinicians participated. For phase I (2005-2007), self-reported EBM competence increased from a median of 2 to 3 (P < 0.001) and the perceived importance of EBM did not change (median = 5). For phase II (2008-2009), before the course, 8-72% graded their competence very low (score of 1-2). After the course, 67-92% of subjects graded their increase in knowledge very high (score of 4-5). The challenges included limited availability of studies relevant to the local reality written in Spanish, participants' limited time and lack of long-term follow-up on practice change. Informal discussion and written evaluation from participants were universally in agreement that more training in EBM is needed.
Conclusions In an EBM course in a resource-poor country, the baseline self-reported competence and experience on EBM were low, and the course had measurable improvements of self-reported competence, perceived utility and readiness to incorporate EBM into their practices. Similar to developed countries, translational research and building the research capacity in developing countries is critical for translating best available evidence into practice.

AB Acceleration of embryonic rotation is a common response to hypoxia among pond snails. It was first characterized in Helisoma trivolvis embryos, which have a pair of sensorimotor neurons that detect hypoxia and release serotonin onto postsynaptic ciliary cells. The objective of the present study was to determine how the hypoxia response is mediated in Lymnaea stagnalis, which differ from H. trivolvis by having both serotonergic and dopaminergic neurons, and morphologically distinct ciliated structures at comparative stages of embryonic development. Time-lapse video recordings of the rotational behavior in L. stagnalis revealed similar rotational features to those previously observed in H. trivolvis, including rotational surges and rotational responses to hypoxia. Serotonin and dopamine increased the rate of rotation with similar potency. In contrast, serotonin was more potent than dopamine in stimulating the ciliary beat frequency of isolated pedal cilia. Isolated apical plate cilia displayed an irregular pattern of ciliary beating that precluded the measurement of ciliary beat frequency. A qualitative assessment of ciliary beating revealed that both serotonin and dopamine were able to stimulate apical plate cilia. The ciliary responses to dopamine were reversible in both pedal and apical plate cilia, whereas the responses to serotonin were only reversible at concentrations below 100 mu mol l(-1). Mianserin, a serotonin receptor antagonist, and SKF83566, a dopamine receptor antagonist, effectively blocked the rotational responses to serotonin and dopamine, respectively. The rotational response to hypoxia was only partially blocked by mianserin, but was fully blocked by SKF83566. These data suggest that, despite the ability of serotonin to stimulate ciliary beating in L. stagnalis embryos, the rotational response to hypoxia is primarily mediated by the transient apical catecholaminergic neurons that innervate the ciliated apical plate.

AB Diapedesis is a dynamic, highly regulated process by which leukocytes are recruited to inflammatory sites. We reported previously that removal of sialyl residues from PMNs enables these cells to become more adherent to EC monolayers and that sialidase activity within intracellular compartments of resting PMNs translocates to the plasma membrane following activation. We did not identify which surface adhesion molecules were targeted by endogenous sialidase. Upon activation, beta 2 integrin (CD11b/CD18) on the PMN surface undergoes conformational change, which allows it to bind more tightly to the ICAM-1 and ICAM-2 on the EC surface. Removal of sialyl residues from CD18 and CD11b, by exogenous neuraminidase or mobilization of PMN sialidase, unmasked activation epitopes, as detected by flow cytometry and enhanced binding to ICAM-1. One sialidase isoform, Neu1, colocalized with CD18 on confocal microscopy. Using an autoperfused microflow chamber, desialylation of immobilized ICAM-1 enhanced leukocyte arrest in vivo. Further, treatment with a sialidase inhibitor in vivo reversed endotoxin-induced binding of leukocytes to ICAM-1, thereby suggesting a role for leukocyte sialidase in the cellular arrest. These data suggest that PMN sialidase could be a physiologic source of the enzymatic activity that removes sialyl residues on beta 2 integrin and ICAM-1, resulting in their enhanced interaction. Thus, PMN sialidase may be an important regulator of the recruitment of these cells to inflamed sites. J. Leukoc. Biol. 90: 313-321; 2011.

AB Matrix Gla protein (MGP) is a calcification inhibitor in vascular tissue that must be carboxylated by vitamin K to function. Evidence suggests circulating uncarboxylated MGP (ucMGP) is elevated in persons with disease characterized by vascular calcification. The primary purpose of this study was to determine cross-sectional and longitudinal associations between plasma ucMGP, vitamin K status, and coronary artery calcium (CAC) in older adults without coronary heart disease. Genetic determinants of ucMGP were also explored. Cross-sectional associations among baseline plasma ucMGP, vitamin K status biomarkers [plasma phylloquinone, uncarboxylated prothrombin (PIVKA-II), serum uncarboxylated osteocalcin (%ucOC)], CAC, and plausible genetic polymorphisms were examined in 438 community-dwelling adults (60-80 y, 59% women). The effect of phylloquinone supplementation (500 mu g/d) for 3 y on plasma ucMGP was determined among 374 participants. At baseline, plasma phylloquinone was lower and %ucOC and PIVKA-II were greater across higher plasma ucMGP quartiles (all P < 0.001, age-adjusted). Major allele homozygotes for MGP rs1800801 and rs4236 had higher plasma ucMGP than heterozygotes or minor allele homozygotes. (P <= 0.004). The decrease in plasma ucMGP was greater in the 190 participants who received phylloquinone (mean +/- SD) (-345 +/- 251 pmol/L) than in the 184 who did not (-40 +/- 196 pmol/L) (P < 0.0001). CAC did not differ according to ucMGP quartile (P = 0.35, age-adjusted). In the phylloquinone-supplemented group, the 3-y change in ucMGP was not associated with the 3-y change in CAC [unstandard beta (SE) = -0.02 (0.02); P = 0.44]. Plasma ucMGP was associated with vitamin K status biomarkers and was reduced following phylloquinone supplementation, suggesting it may be a useful marker of vitamin K status in vascular tissue. Plasma ucMGP did not reflect CAC in healthy older adults. J. Nutr. 141: 1529-1534, 2011.

AB Intraductal papillary mucinous neoplasm (IPMN) consists of four epithelial subtypes. Of those, pancreatobiliary and oncocytic types are recently recognized and relatively uncommon, and usually exhibit high-grade dysplasia. The biological properties and molecular characteristics of these two types have not been well documented. The few molecular studies of the oncocytic type showed absence of KRAS mutations commonly seen in the other subtypes, raising the possibility that the oncocytic type is distinct from the other subtypes. Thus, we examined clinicopathological features and molecular alterations of the two subtypes. The study cohort consisted of 12 pancreatobiliary and 18 oncocytic IPMN cases. KRAS, BRAF, and PIK3CA mutations and TP53, SMAD4, and beta-catenin expression were analysed, and the results of molecular and clinicopathological profiles were compared between the two subtypes. KRAS mutations were identified in the oncocytic type, but less frequently than the pancreatobiliary type (17% versus 58%, p = 0.048). BRAF mutation was found in a single oncocytic tumour, and no PIK3CA mutations were seen in any of the study cohort. TP53 overexpression was less frequent in the oncocytic type than in the pancreatobiliary type (11% versus 58%, p = 0.013). Invasive components were present in 50% of the oncocytic and 92% of the pancreatobiliary types, with lymph node metastasis more frequently seen in the latter, corresponding to better outcomes in the former (5-year survival rates: 93% versus 32%, p = 0.014). Our demonstration of KRAS and BRAF mutations in the oncocytic-type IPMN supports a role for the activation of the RAS-MAPK pathway in this tumour type. However, the less frequent TP53 overexpression associated with the significantly lower rates of invasion and nodal disease in the oncocytic type correlates with better outcomes compared to the pancreatobiliary type.

AB MicroRNAs are short noncoding RNAs that usually reduce translation of messenger RNAs. Changes in microRNA-192 (miR-192) are reported in states of renal fibrosis. New evidence supports a role for miR-192 and its target miR-200b/c in transforming growth factor-beta 1 regulation of its own expression and that of collagens in mesangial cells, with a possible role in diabetic nephropathy. As there is controversy on the role of these microRNAs in diabetic nephropathy, more work is needed. Kidney International (2011) 80, 334-337. doi:10.1038/ki.2011.165

AB In population groups where head pose cannot be assumed to be constant during a magnetic resonance spectroscopy examination or in difficult-to-shim regions of the brain, real-time volume of interest, frequency, and shim optimization may be necessary. We investigate the effect of pose change on the B-0 homogeneity of a (2 cm)(3) volume and observe typical first-order shim changes of 1 mu T/m per 1 degrees rotation (chin down to up) in four different volumes of interest in a single volunteer. An echo planar imaging volume navigator was constructed to measure and apply in real-time within each pulse repetition time: volume of interest positioning, frequency adjustment, and first-order shim adjustment. This volume navigator is demonstrated in six healthy volunteers and achieved a mean linewidth of 4.4 Hz, similar to that obtained by manual shim adjustment of 4.9 Hz. Furthermore, this linewidth is maintained by the volume navigator at 4.9 Hz in the presence of pose change. By comparison, a mean linewidth of 7.5 Hz was observed, when no correction was applied.

AB A 20-channel phased-array coil for MRI of mice has been designed, constructed, and validated with bench measurements and high-resolution accelerated imaging. The technical challenges of designing a small, high density array have been overcome using individual small-diameter coil elements arranged on a cylinder in a hexagonal overlapping design with adjacent low impedance preamplifiers to further decouple the array elements. Signal-to-noise ratio (SNR) and noise amplification in accelerated imaging were simulated and quantitatively evaluated in phantoms and in vivo mouse images. Comparison between the 20-channel mouse array and a length-matched quadrature driven small animal birdcage coil showed an SNR increase at the periphery and in the center of the phantom of 3- and 1.3-fold, respectively. Comparison with a shorter but SNR-optimized birdcage coil (aspect ratio 1:1 and only half mouse coverage) showed an SNR gain of twofold at the edge of the phantom and similar SNR in the center. G-factor measurements indicate that the coil is well suited to acquire highly accelerated images. Magn Reson Med 66:584-595, 2011. (C) 2011 Wiley-Liss, Inc.

AB Background: We assessed the risk of coronary heart disease (CHD) in subjects with metabolic syndrome using different reference categories and focusing on the number of traits in the cluster.
Methods: For 15 years, we followed 840 subjects from the general population living in Bruneck, northeastern Italy, aged 40-79 years, without CHD at baseline. Metabolic syndrome was diagnosed at baseline using American Heart Association/National Heart, Lung, and Blood Institute criteria. Subjects with the syndrome were compared to subjects without, as well as to subjects without any metabolic abnormality, using Cox models adjusted for sex, age, smoking, and low-density lipoprotein-cholesterol. There were 89 incident CHD cases.
Results: In subjects with the metabolic syndrome, the risk of CHD was < approx sign > 1.5-fold higher when subjects without the syndrome were the reference category. CHD risk, however, was 12.5-fold higher (95% confidence interval [CI], 1.7-92.7, P = 0.014) when subjects without any metabolic abnormality composed the reference category. As compared to subjects with no abnormalities (who had a trivial number of CHD events), the risk increased from subjects with one (hazard ratio 7.6, 95% CI 1.0-56.5, P = 0.047) to those with 2, 3, and 4/5 abnormalities (11.6, 1.6-84.9, P = 0.016; 12.9, 1.7-96.0, P = 0.013; and 10.1, 1.3-79.2, P = 0.028), respectively.
Conclusions: When compared to the reference category of people without any metabolic abnormality, those with the metabolic syndrome had high cardiovascular risk. However, in the Bruneck population, the risk of CHD seems to be similar in subjects having two or three to five clinical features of metabolic syndrome. Therefore, the clinical utility of identifying subjects with the syndrome using current diagnostic criteria remains uncertain and might be the focus of further specific studies.

AB The objective of the study was to understand the role in vivo of elevated plasma free fatty acids (FFA), insulin, and glucose levels in the development of steatosis and altered mitochondrial gene/protein expression. We studied 4 groups of Sprague-Dawley rats: (1) high-fat diet (HFD), (2) high-dose streptozotocin-induced diabetes (T1DM), (3) low-dose streptozotocin-induced diabetic rats on an HFD (T2DM), and (4) controls. Liver histology and expression of genes/proteins related to mitochondrial fatty acid oxidation and biogenesis were analyzed. Despite an attempt to compensate by increasing expression of genes of fatty acid oxidation (carnitine palmitoyl transferase-l/medium chain acyl-CoA dehydrogenase), the HFD and diabetic groups developed marked steatosis and suffered a significant reduction in mitochondrial biogenesis gene expression (nuclear respiratory factor 11 transcriptional factor A, mitochondrial). In T2DM rats, the combination of high glucose and FFA unexpectedly did not lead to greater fat accumulation than HFD alone. Greater steatosis in HFD vs T2DM (P < .001) correlated with impairment in the gene expression of PPAR-alpha (ie, fatty acid oxidation) and PGCl alpha, a major coactivator for mitochondrial biogenesis. Steatosis was not severe in insulin-deficient T1DM rats despite very elevated FFA and glucose levels. Increased carnitine palmitoyl transferase-1/medium chain acyl-CoA dehydrogenase/PPAR-alpha gene expression suggested inadequate adaptation to high FFA in both T1DW/T2DM rats. Hyperinsulinemia combined with elevated FFA is the key metabolic factor driving hepatic lipogenesis in vivo (HFD rats). Mitochondrial biogenesis (nuclear respiratory factor 1; transcriptional factor A, mitochondrial) is highly susceptible to FFA-induced steatosis. In contrast, hyperglycemia does not have an additive effect (T2DM) and leads to only a modest degree of steatosis in the absence of hyperinsulinemia, even when FFA are extremely elevated as in T1DM rats.

AB Insulin resistance is closely associated with numerous metabolic disorders. Although studies have supported the importance of insulin resistance in carcinogenesis, the existing data have not established its relevance in the context of lung cancer. The aim of the present case-control study was to evaluate the association between insulin resistance and lung cancer after adjusting for possible confounders. Homeostasis model assessment of insulin resistance (HOMA-IR) and serum leptin and adiponectin levels were determined in 81 lung cancer cases and 162 age-and sex-matched controls; anthropometric and lifestyle variables were recorded. Mean HOMA-IR in the cases was more than 2-fold higher compared with the mean value of controls (P < .001). Among controls, HOMA-IR correlated positively with serum leptin (r = 0.16; P = .04), body mass index (r = 0.43; 13 = .0001), and waist-to-hip ratio (r = 0.21; P = .01) but negatively with serum adiponectin (r = -0.29; P = .0002). As expected, smoking was associated with an approximately 10-fold increase in lung cancer risk in multiple logistic regression models. A positive association between HOMA-IR, treated as continuous variable, and lung cancer (odds ratio [OR] = 1.52, 95% confidence interval [CI]: 1.16-1.99, P = .002, model 1) was demonstrated, which persisted after adjustment for somatometric and lifestyle variables (OR = 2.36, 95% CI: 1.00-5.55, P =.05, model 2). When serum adiponectin was also taken into account, the association seemed fairly robust (OR = 2.58, 95% CI: 1.11-6.01, P = .03, model 3); on the contrary, when serum leptin was added, the association remained positive, but lost its statistical significance (OR = 1.76, 95% CI: 0.78-3.98, P = .17, model 4). In the fully adjusted model, HOMA-IR was still positively, but only marginally, associated with lung cancer risk (OR = 2.02, 95% CI: 0.88-4.65, P = .10, model 5). Insulin resistance may represent a meaningful risk factor for lung cancer. (C) 2011 Elsevier Inc. All rights reserved.

AB The aim of this study was to assess the biodistribution and pharmacokinetics of epidermal growth factor receptor (EGFR)-targeted polymer-blend nanoparticles loaded with the anticancer drugs lonidamine and paclitaxel. Plasma, tumor, and tissue distribution profiles were quantified in an orthotopic animal model of multidrug-resistant breast cancer and were compared to treatment with nontargeted nanoparticles and to treatment with drug solution. A poly(d, l-lactide-co-glycolide)-poly(ethylene glycol)-EGFR targeting peptide (PLGA-PEG-EFGR peptide) construct was synthesized for incorporation in poly(epsilon-caprolactone) particles to achieve active EGFR targeting. An isocratic high-pressure liquid chromatography method was developed to quantify lonidamine and paclitaxel in mice plasma, tumors, and vital organs. The targeted nanoparticles demonstrated a superior pharmacokinetic profile relative to drug solution and nontargeted nanoparticles, particularly for lonidamine delivery. The first target site of accumulation was the liver, followed by the kidneys, and then the tumor mass; maximal tumor accumulation occured at 3 hours after administration. Lonidamine-paclitaxel combination therapy administered via EGFR-targeted polymer-blend nanocarriers may become a viable platform for the future treatment of multidrug-resistant cancer.
From the Clinical Editor: In this study the biodistribution and pharmacokinetics of epidermal growth factor receptor (EGFR)-targeted polymer-blend nanoparticles loaded with lonidamine and paclitaxel were assessed. The targeted nanoparticles demonstrated a superior pharmacokinetic profile relative to drug solution and nontargeted nanoparticles, paving the way to new therapeutic approaches for multidrug-resistant malignancies.

AB Genome-wide association studies have identified 32 loci influencing body mass index, but this measure does not distinguish lean from fat mass. To identify adiposity loci, we meta-analyzed associations between similar to 2.5 million SNPs and body fat percentage from 36,626 individuals and followed up the 14 most significant (P < 10(-6)) independent loci in 39,576 individuals. We confirmed a previously established adiposity locus in FTO (P = 3 x 10(-26)) and identified two new loci associated with body fat percentage, one near IRS1 (P = 4 x 10(-11)) and one near SPRY2 (P = 3 x 10(-8)). Both loci contain genes with potential links to adipocyte physiology. Notably, the body-fat-decreasing allele near IRS1 is associated with decreased IRS1 expression and with an impaired metabolic profile, including an increased visceral to subcutaneous fat ratio, insulin resistance, dyslipidemia, risk of diabetes and coronary artery disease and decreased adiponectin levels. Our findings provide new insights into adiposity and insulin resistance.

AB Noncoding variants at human chromosome 9p21 near CDKN2A and CDKN2B are associated with type 2 diabetes(1-4), myocardial infarction(5-7), aneurysm(8), vertical cup disc ratio(9) and at least five cancers(10-16). Here we compare approaches to more comprehensively assess genetic variation in the region. We carried out targeted sequencing at high coverage in 47 individuals and compared the results to pilot data from the 1000 Genomes Project. We imputed variants into type 2 diabetes and myocardial infarction cohorts directly from targeted sequencing, from a genotyped reference panel derived from sequencing and from 1000 Genomes Project low-coverage data. Polymorphisms with frequency >5% were captured well by all strategies. Imputation of intermediate-frequency polymorphisms required a higher density of tag SNPs in disease samples than is available on first-generation genome-wide association study (GWAS) arrays. Our association analyses identified more comprehensive sets of variants showing equivalent statistical association with type 2 diabetes or myocardial infarction, but did not identify stronger associations than the original GWAS signals.

AB Functional characterization of the human genome requires tools for systematically modulating gene expression in both loss-of-function and gain-of-function experiments. We describe the production of a sequence-confirmed, clonal collection of over 16,100 human open-reading frames (ORFs) encoded in a versatile Gateway vector system. Using this ORFeome resource, we created a genome-scale expression collection in a lentiviral vector, thereby enabling both targeted experiments and high-throughput screens in diverse cell types.

AB The treatment of peripheral artery disease (PAD) focuses on risk factor modification, cardiovascular event reduction, limb viability, and symptom improvement. Hypertension, hyperlipidemia, and diabetes mellitus should all be controlled to recommended target levels, and smoking cessation is vital. Antiplatelet therapies, such as aspirin or clopidogrel, should be administered in all patients unless contraindicated. Whenever possible, patients who present with claudication should be offered a regimen comprised of both medical and exercise therapy, which often results in substantial improvement in symptoms. For patients presenting with more-advanced disease, such as acute limb ischemia, critical limb ischemia, and severely-limiting symptoms of PAD, revascularization is often necessary. As a result of the rapid evolution in endovascular revascularization technology and expertise, many patients with PAD can be treated percutaneously. Therefore, in this Review, we will focus on medical therapy and endovascular revascularization of patients with PAD, with reference to surgical bypass in specific clinical scenarios.

AB The amyloid hypothesis (AH) of Alzheimer's disease (AD) posits that the fundamental cause of AD is the accumulation of the peptide amyloid beta(A beta) in the brain. This hypothesis has been supported by observations that genetic defects in amyloid precursor protein (APP) and presenilin increase A beta production and cause familial AD (FAD). The AH is widely accepted but does not account for important phenomena including recent failures of clinical trials to impact dementia in humans even after successfully reducing A beta deposits. Herein, the AH is viewed from the broader overarching perspective of the myelin model of the human brain that focuses on functioning brain circuits and encompasses white matter and myelin in addition to neurons and synapses. The model proposes that the recently evolved and extensive myelination of the human brain underlies both our unique abilities and susceptibility to highly prevalent age-related neuropsychiatric disorders such as late onset AD (LOAD). It regards oligodendrocytes and the myelin they produce as being both critical for circuit function and uniquely vulnerable to damage. This perspective reframes key observations such as axonal transport disruptions, formation of axonal swellings/sphenoids and neuritic plaques, and proteinaceous deposits such as A beta and tau as by-products of homeostatic myelin repair processes. It delineates empirically testable mechanisms of action for genes underlying FAD and LOAD and provides" upstream" treatment targets. Such interventions could potentially treat multiple degenerative brain disorders by mitigating the effects of aging and associated changes in iron, cholesterol, and free radicals on oligodendrocytes and their myelin.

AB The decision to have bariatric surgery should be based on accurate information on possible risks and benefits of all treatment options. The goal of this study was to determine whether a video-based bariatric decision aid intervention results in superior decision quality compared to an educational booklet. We conducted a prospective, randomized controlled trial among adult patients in a single health plan who met standard criteria for bariatric surgery. Patients were randomly assigned to review either a video-based decision aid (intervention) or an educational booklet on bariatric surgery (control). Changes in patient decision quality were assessed using bariatric-specific measures of knowledge, values, and treatment preference after 3 months. Of 152 eligible participants, 75 were randomly assigned to the intervention and 77 to the control. The 3-month follow-up rate was 95%. Among all participants, significant improvements were observed in knowledge (P < 0.001), values concordance (P = 0.009), decisional conflict (P < 0.001), decisional self-efficacy (P < 0.001), and in the proportion who were "unsure" of their treatment choice (P < 0.001). The intervention group had larger improvements in knowledge (P = 0.03), decisional conflict (P = 0.03), and outcome expectancies (P = 0.001). The proportion of participants choosing bariatric surgery did not differ significantly between groups, although there was a trend toward decreased surgical choice in the intervention group (59% booklet vs. 42% video at 3 months; P = 0.16). The use of bariatric surgery decision aids was followed by improved decision quality and reduced uncertainty about treatment at 3 months. The video-based decision aid appeared to have a greater impact than the educational booklet on patient knowledge, decisional conflict, and outcome expectancies.

ID ATHEROSCLEROSIS; EXPRESSION
AB The elegant study by Wu et al (1) presents additional evidence that vascular cell adhesion molecule-1 (VCAM-1) imaging in atherosclerotic mice is feasible and of substantial preclinical value. The current study is well performed and enhances the diagnostic armamentarium of ultrasonography (US) in molecular imaging of the endothelium. The technique is likely to have a substantial impact in the preclinical arena, where it will assist in the elucidation of endothelial biology and the assessment of new therapies in mice. The impact of the technique in the clinical arena, however, is likely to be more limited. Although final judgment will need to be held until large animal studies are performed with this approach, it is likely that more tomographic and quantitative techniques that are capable of imaging the coronary arteries, such as magnetic resonance (MR) imaging and positron emission tomography (PET), will be of greatest value in the clinical setting.

AB Purpose: To assess the impact on length of stay and rate of major adverse cardiovascular events of a cardiac computed tomographic (CT) angiography-guided algorithm to examine patients who present to the emergency department (ED) with low-to intermediate-risk chest pain.
Materials and Methods: The study was approved by the institutional review board, and all patients gave written informed consent. Two hundred three consecutive patients (mean age, 55 years +/- 11 [standard deviation]; 123 men) with low-to intermediate-risk ischemic-type chest pain were prospectively enrolled. Patients underwent initial cardiac CT angiography with subsequent treatment determined by reference to findings at cardiac CT angiography; patients without overt plaque were immediately discharged from the hospital, patients with nonobstructive plaque and mild-to-moderate stenoses were discharged after a negative 6-hour troponin level, and patients with severe stenoses were admitted to the hospital. Discharged patients were followed up for a mean of 14.2 months. Additionally, length of stay and safety outcomes among these patients were compared with those in 102 consecutive patients with low-to intermediate-risk chest pain who presented to the ED and underwent a standard of care (SOC) work-up without cardiac CT angiography. One-way analysis of variance with Bonferroni correction was used to compare length of stay between groups.
Results: Cardiac CT angiography findings in the 203 patients who underwent cardiac CT angiography were as follows: Sixty-five (32%) patients had no plaque, 107 (53%) had nonobstructive plaque, and 31 (15%) had severe stenoses. At follow-up, there were no deaths or cases of acute coronary syndrome (cardiac CT angiography, 0%, 95% confidence interval [CI]: 0%, 1.85%; SOC, 0%, 95% CI: 0%, 3.63%), and the rate of readmission to the hospital because of chest pain was higher with the SOC approach (9% vs 1%, P = .01). Mean ED length of stay was lower with cardiac CT angiography (6.62 hours +/- 0.38 after a single troponin level and 9.15 hours +/- 0.30 after serial troponin levels) than with the SOC approach (11.62 hours +/- 0.47, P < .001).
Conclusion: Tailoring troponin measurement to cardiac CT angiography findings is safe and allows early discharge of patients with low-to intermediate-risk chest pain, resulting in reduced length of stay. (C) RSNA, 2011

AB Purpose: To prospectively compare traditional filtered back projection (FBP) and iterative image reconstruction for the evaluation of heavily calcified arteries with coronary computed tomography (CT) angiography.
Materials and Methods: The study had institutional review board approval and was HIPAA compliant. Written informed consent was obtained from all patients. Fifty-five consecutive patients (35 men, 20 women; mean age, 58 years +/- 12 [standard deviation]) with Agatston scores of at least 400 underwent coronary CT angiography and cardiac catheterization. Image data were reconstructed with both FBP and iterative reconstruction techniques with corresponding cardiac algorithms. Image noise and subjective image quality were compared. To objectively assess the effect of FBP and iterative reconstruction on blooming artifacts, volumes of circumscribed calcifications were measured with dedicated volume analysis software. FBP and iterative reconstruction series were independently evaluated for coronary artery stenosis greater than 50%, and their diagnostic accuracy was compared, with cardiac catheterization as the reference standard. Statistical analyses included paired t tests, Kruskal-Wallis analysis of variance, and a modified McNemar test.
Results: Image noise measured significantly lower (P = .011-.035) with iterative reconstruction instead of FBP. Image quality was rated significantly higher (P = .031 and .042) with iterative reconstruction series than with FBP. Calcification volumes measured significantly lower (P = .019 and .026) with iterative reconstruction (44.3 mm(3) +/- 64.7 and 46.2 mm(3) +/- 68.8) than with FBP (54.5 mm(3) +/- 69.5 and 56.3 mm(3) +/- 72.5). Iterative reconstruction significantly improved some measures of per-segment diagnostic accuracy of coronary CT angiography for the detection of significant stenosis compared with FBP (accuracy: 95.9% vs 91.8%, P = .0001; specificity: 95.8% vs 91.2%, P = .0001; positive predictive value: 76.9% vs 61.1%, P = .0001).
Conclusion: Iterative reconstruction reduces image noise and blooming artifacts from calcifications, leading to improved diagnostic accuracy of coronary CT angiography in patients with heavily calcified coronary arteries. (C) RSNA, 2011

AB Background: Food intake fluctuates throughout the menstrual cycle; it is greater during the early follicular and luteal phases than in the late follicular (periovulatory) phase. Ovarian steroids can influence brain areas that process food-related information, but the specific contribution of individual hormones and the importance of the prandial state remain unknown.
Objective: The objective was to examine whether brain activation during food visualization is affected by changes in estradiol concentration in the fasted and fed conditions.
Design: Nine eumenorrheic, lean young women [mean (+/- SD) age: 26.2 +/- 3.2 y; body mass index (in kg/m(2)): 22.4 +/- 1.2] completed 2 visits, one in the early (low estradiol) and one in the late (high estradiol) follicular phase of their menstrual cycle. At each visit, subjects underwent functional magnetic resonance imaging while they viewed food and nonfood images, before and after a standardized meal. Region-of-interest analysis was used to examine the effect of follicular phase and prandial state on brain activation (food > nonfood contrast) and its association with estradiol concentration.
Results: Differences were identified in the inferior frontal and fusiform gyri. In these areas, visualization of food elicited greater activation in the fed state than during fasting but only in the late follicular phase, when estradiol concentration was high. The change in estradiol concentration across the follicular phase (late minus early) was inversely correlated with the change in fusiform gyrus activation in the fasted state but not in the fed state.
Conclusion: Our findings suggest that estradiol may reduce food intake by decreasing sensitivity to food cues in the ventral visual pathway under conditions of energy deprivation. This trial was registered at clinicaltrials.gov as NCT00130117. Am J Clin Nutr 2011;94:377-84.

AB Background: The optimal public health strategy for maintaining 25-hydroxyvitamin D [25(OH) D] concentrations in schoolchildren in Mongolia is unknown.
Objective: The objective was to compare the effectiveness of different supplement and fortified milk regimens to increase 25(OH) D concentrations in Mongolian schoolchildren.
Design: Twenty-one classrooms of 579 children aged 9-11 y were randomized to interventions with an equivalent content of vitamin D-3: 1) a one-time seasonal supplement of 13,700 IU, 2) 300 IU/d from supplements, 3) 300 IU/d from fortified ultra-high-temperature pasteurized milk from the United States, 4) 300 IU/d from fortified pasteurized Mongolian milk, or 5) unfortified pasteurized Mongolian milk (control).
Results: In January, the mean (+/- SD) serum 25(OH) D concentration was 8 +/- 4 ng/mL (20 +/- 10 nmol/L), and 98% of the children had a concentration <20 ng/mL (50 nmol/L). In March, concentrations were 8 +/- 4 ng/mL after unfortified milk, 20 +/- 6 ng/mL after fortified Mongolian milk, 29 +/- 10 ng/mL after fortified US milk, 21 +/- 6 ng/mL after daily supplements, and 12 +/- 4 ng/mL after seasonal supplements (each greater than unfortified milk, P < 0.01). Seasonal supplementation was less effective than was daily supplementation (P < 0.0001). Despite consuming daily supplements or fortified milk, 41% of the children still had concentrations <20 ng/mL (50 nmol/L). Children with lower baseline 25(OH) D concentrations experienced slightly larger 25(OH) D responses to intervention than did children with higher concentrations (P = 0.002).
Conclusions: In this population with extremely low vitamin D concentrations, delivery of 300 IU vitamin D/d via supplements or in fortified milk improved 25(OH) D concentrations but failed to raise concentrations uniformly to >20 ng/mL (50 nmol/L). The daily low-dose intervention was superior to the seasonal larger-dose intervention. Higher doses may be needed to prevent deficiency in schoolchildren in Mongolia and at other northern latitudes. This trial is registered at clinicaltrials.gov as NCT00886379. Am J Clin Nutr 2011; 94: 578-84.

AB PURPOSE OR BACKGROUND: Interleukin (IL)-10 is an immunoregulatory cytokine that is produced by a variety of cell types, such as macrophages and activated monocytes. IL-10 possesses numerous anti-inflammatory, anti-thrombotic and anti-atherosclerotic properties. Furthermore, patients with acute coronary syndrome have been demonstrated to have reduced levels of IL-10 compared to their stable counterparts. For these reasons, it has been proposed that IL-10 plays a protective role in both atherogenesis and plaque vulnerability. However, 2 short-term studies on the prognostic utility of IL-10 in patients with acute coronary syndrome have provided conflicting results, with one study showing that reduced levels of IL-10 were predictors of adverse outcomes and another showing that elevated levels predicted poor outcomes. The objective of the present study was to investigate the long-term prognostic significance of baseline IL-10 levels in patients with acute coronary syndrome.
METHODS: Baseline plasma IL-10 levels were measured in 193 well-characterized male patients with acute coronary syndrome who were referred for coronary angiography and followed prospectively for 5 years for the development of major adverse cardiovascular events.
RESULTS: After controlling for a variety of baseline variables (including established biomarkers such as high-sensitivity C-reactive protein and N-terminal-pro-B-type natriuretic peptide), plasma IL-10 levels (whether analyzed as a continuous variable or as a categorical variable using receiver operating characteristic-derived cut point) were a strong and independent predictor of the composite outcome of death or non-fatal myocardial infarction when using a Cox proportional hazards model.
CONCLUSIONS: These data demonstrate that, despite biologic plausibility for IL-10 as being a cardioprotective cytokine, elevated baseline plasma levels of IL-10 are a strong and independent predictor of long-term adverse cardiovascular outcomes in patients with acute coronary syndrome.

AB BACKGROUND: Myocardial ischemia is a strong trigger of N-terminal pro-B-type natriuretic peptide (NT-proBNP) release. As ischemia precedes necrosis in acute myocardial infarction, we hypothesized that NT-proBNP might be useful in the early diagnosis and risk stratification of patients with suspected acute myocardial infarction.
METHODS: In a prospective multicenter study, NT-proBNP was measured at presentation in 658 consecutive patients with acute chest pain. The final diagnosis was adjudicated by 2 independent cardiologists. Patients were followed long term regarding mortality.
RESULTS: Acute myocardial infarction was the adjudicated final diagnosis in 117 patients (18%). NT-proBNP levels at presentation were significantly higher in acute myocardial infarction as compared with patients with other final diagnoses (median 886 pg/mL vs 135 pg/mL, P <.001). The diagnostic accuracy of NT-proBNP for acute myocardial infarction as quantified by the area under the receiver operating characteristic curve (AUC) was 0.79 (95% confidence interval [CI], 0.75-0.83). When added to cardiac troponin T, NT-proBNP significantly increased the AUC from 0.89 (95% CI, 0.84-0.93) to 0.91 (95% CI, 0.88-0.94; P = .033). Cumulative 24-month mortality rates were 0% in the first, 1.3% in the second, 8.3% in the third, and 23.3% in the fourth quartile of NT-proBNP (P <.001). NT-proBNP (AUC 0.85, 95% CI, 0.81-0.89) predicted all-cause mortality independently of and more accurately than both cardiac troponin T (AUC 0.66, 95% CI, 0.58-0.74; P <.001) and the Thrombolysis in Myocardial Infarction risk score (AUC 0.79, 95% CI, 0.74-0.84; P <.001). Net reclassification improvement (Thrombolysis in Myocardial Infarction vs additionally NT-proBNP) was 0.188 (P <.009), and integrated discrimination improvement was 0.100 (P <.001).
CONCLUSIONS: Use of NT-proBNP improves the early diagnosis and risk stratification of patients with suspected acute myocardial infarction. (C) 2011 Elsevier Inc. All rights reserved. The American Journal of Medicine (2011) 124, 731-739

AB Background Many details of the negative relationship between perceived racial/ethnic discrimination and health are poorly understood.
Purpose The purpose of this study was to examine racial/ethnic differences in the relationship between perceived discrimination and self-reported health, identify dimensions of discrimination that drive this relationship, and explore psychological mediators.
Methods Asian, Black, and Latino(a) adults (N = 734) completed measures of perceived racial/ethnic discrimination, self-reported health, depression, anxiety, and cynical hostility.
Results The association between perceived discrimination and poor self-reported health was significant and did not differ across racial/ethnic subgroups. Race-related social exclusion and threat/harassment uniquely contributed to poor health for all groups. Depression, anxiety, and cynical hostility fully mediated the effect of social exclusion on health, but did not fully explain the effect of threat.
Conclusions Our results suggest that noxious effects of race-related exclusion and threat transcend between-group differences in discriminatory experiences. The effects of race-related exclusion and threat on health, however, may operate through different mechanisms.

AB Background The impact of measurement methods on the relationship between depression and HIV treatment adherence has not been adequately examined.
Purpose The purpose of this paper is to examine the relationship between clinician- and patient-rated depression and HIV medication adherence.
Methods The participants were 91 HIV-infected individuals in methadone maintenance. Depression was assessed via clinician ratings (Clinical Global Impression Scale and Montgomery Asberg Depression Rating Scale) and self-report (Beck Depression Inventory-Short Form). Clinicians rated substance abuse using the Clinical Global Impression Scale and a structured interview. HIV medication adherence was measured over the following 2 weeks using electronic caps.
Results Each unit increase in the Clinical Global Impression Scale was associated with 75% increased odds of nonadherence (OR = 1.75, p = 0.002, 95% CI = 1.23-2.48). Similarly, for each standard deviation Montgomery Asberg Depression Rating Scale increase, there was a 2.6-fold increased odds of nonadherence (OR = 2.60, p = 0.001, 95% CI = 1.45-4.67). Substance abuse and self-reported depression severity were not significantly related to adherence.
Conclusions Clinician-rated depression severity was a strong predictor of nonadherence. Assessment methods may influence the relationship between depression and HIV nonadherence.

AB Objective: To investigate the relationship between supply of subspecialty care and type of procedure preferentially performed for early stage breast cancer.
Background: Three surgical options exist for early stage breast cancer: (1) breast conserving surgery (BCS), (2) mastectomy with reconstruction (RECON), and (3) mastectomy alone. Current guidelines recommend that surgical treatment decisions should be based on patient preference if a patient is eligible for all 3. However, studies demonstrate persistent variation in the use of BCS and RECON.
Methods: Patients undergoing an operation for DCIS or stage I or II breast cancer at NCCN institutions between 2000 and 2006 were identified. Institutional procedure rates were determined. Spearman correlations measured the association between procedure types. Patient-level logistic regression models investigated predictors of procedure type and association with institutional supply of subspecialty care.
Results: Among 10,607 patients, 19% had mastectomy alone, 60% BCS, and 21% RECON. The institutional rate of BCS and RECON were strongly correlated (r = -0.80, P = 0.02). Institution was more important than all patient factors except age in predicting receipt of RECON or BCS. RECON was more likely for patients treated at an institution with a greater supply of reconstructive surgeons or where patients live further from radiation facilities. RECON was less likely at institutions with longer waiting times for surgery with reconstruction.
Conclusions: Even within the NCCN, a consortium of multidisciplinary cancer centers, the use of BCS and mastectomy with reconstruction substantially varies by institution and correlates with the supply of subspecialty care.

AB Objective-The goal of this study was to determine the role of Cdc42 in embryonic vasculogenesis and the underlying mechanisms.
Methods and Results-By using genetically modified mouse embryonic stem (ES) cells, we demonstrate that ablation of the Rho GTPase Cdc42 blocks vascular network assembly during embryoid body (EB) vasculogenesis without affecting endothelial lineage differentiation. Reexpression of Cdc42 in mutant EBs rescues the mutant phenotype, establishing an essential role for Cdc42 in vasculogenesis. Chimeric analysis revealed that the vascular phenotype is caused by inactivation of Cdc42 in endothelial cells rather than surrounding cells. Endothelial cells isolated from Cdc42-null EBs are defective in directional migration and network assembly. In addition, activation of atypical protein kinase C iota (PKC iota) is abolished in Cdc42-null endothelial cells, and PKC iota ablation phenocopies the vascular abnormalities of the Cdc42-null EBs. Moreover, the inhibitory phosphorylation of glycogen synthase kinase-3 beta (GSK-3 beta) at Ser9 depends on Cdc42 and PKC iota, and expression of kinase-dead GSK-3 beta in Cdc42-null EBs promotes the formation of linear endothelial segments without branches. These results suggest that PKC iota and GSK-3 beta are downstream effectors of Cdc42 during vascular morphogenesis.
Conclusion-Cdc42 controls vascular network assembly but not endothelial lineage differentiation by activating PKC iota during embryonic vasculogenesis. (Arterioscler Thromb Vasc Biol. 2011;31:1861-1870.)

AB Objective-Aldosterone (Aldo) antagonism prevents cardiovascular mortality by unclear mechanisms. Aldo binds to the mineralocorticoid receptor (MR), a ligand-activated transcription factor, which is expressed in human vascular cells. Here we define the early Aldo-regulated vascular transcriptome and investigate the mechanisms of gene regulation by Aldo in the vasculature that may contribute to vascular disease.
Methods and Results-Gene expression profiling of Aldo-treated mouse aortas identified 72 genes regulated by Aldo. These genes are overrepresented in Gene Ontology categories involved in vascular function and disease. Quantitative reverse transcription-polymerase chain reaction was used to confirm and further explore mechanisms of vascular gene regulation by Aldo. Aldo-regulated vascular gene expression was inhibited by actinomycin D and MR antagonists supporting a transcriptional MR-dependent mechanism. Aldo regulation of a subset of genes was enhanced in the setting of vascular endothelial denudation and blocked by the free radical scavenger Tempol, supporting synergy between Aldo and vascular injury that is oxidative stress dependent. In the aortic arch, a region predisposed to atherosclerosis, the injury-enhanced genes also demonstrated enhanced expression compared with the descending aorta, both at baseline and after Aldo exposure. Furthermore, the clinically beneficial MR antagonist spironolactone inhibited expression of the identified genes in aortic tissue from humans with atherosclerosis.
Conclusion-This study defines the Aldo-regulated vascular transcriptome and characterizes a subset of proatherogenic genes with enhanced Aldo-stimulated, oxidative stress-dependent expression in the setting of vascular injury and in areas predisposed to atherosclerosis. Inhibition of MR regulation of these genes may play a role in the protective effects of Aldo antagonists in patients with vascular disease, and these pathways may provide novel drug targets to prevent atherosclerosis in humans.

AB Objective-Earlier studies have suggested that a common genetic architecture underlies the clinically heterogeneous polygenic Fredrickson hyperlipoproteinemia (HLP) phenotypes defined by hypertriglyceridemia (HTG). Here, we comprehensively analyzed 504 HLP-HTG patients and 1213 normotriglyceridemic controls and confirmed that a spectrum of common and rare lipid-associated variants underlies this heterogeneity.
Methods and Results-First, we demonstrated that genetic determinants of plasma lipids and lipoproteins, including common variants associated with plasma triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) from the Global Lipids Genetics Consortium were associated with multiple HLP-HTG phenotypes. Second, we demonstrated that weighted risk scores composed of common TG-associated variants were distinctly increased across all HLP-HTG phenotypes compared with controls; weighted HDL-C and LDL-C risk scores were also increased, although to a less pronounced degree with some HLP-HTG phenotypes. Interestingly, decomposition of HDL-C and LDL-C risk scores revealed that pleiotropic variants (those jointly associated with TG) accounted for the greatest difference in HDL-C and LDL-C risk scores. The APOE E2/E2 genotype was significantly overrepresented in HLP type 3 versus other phenotypes. Finally, rare variants in 4 genes accumulated equally across HLP-HTG phenotypes.
Conclusion-HTG susceptibility and phenotypic heterogeneity are both influenced by accumulation of common and rare TG-associated variants. (Arterioscler Thromb Vasc Biol. 2011; 31: 1916-1926.)

AB The significant increase in the detection and treatment of ductal carcinoma in situ (DCIS) since the introduction of screening mammography has not been accompanied by the anticipated reduction in invasive breast cancer (IBC) incidence. The prevalence of DCIS requires a reexamination of the population level effects of detecting and treating DCIS. To further our understanding of the possible impact of DCIS diagnosis and treatment on IBC incidence in the U.S., we simulated breast cancer incidence over 25 years under various assumptions regarding the baseline incidence of IBC and the progression of DCIS to IBC. The simulations demonstrate a tradeoff between the expected increased incidence of IBC absent any DCIS detection and treatment and the rate of progression of DCIS to IBC. Our analyses indicate that a high progression of DCIS to IBC implies a significant increase in incidence of IBC over what is observed had we not detected and treated DCIS. Conversely, if we assume that there would not have been a significant increase over and above the observed incidence evident in SEER, then our model indicates that the rate of DCIS progression to clinically significant IBC is low. Given the tradeoff illustrated by our model, we must reevaluate the assumption that DCIS is a short-term obligate precursor of invasive cancer and instead focus on further exploration of the true natural history of DCIS.

AB Dendritic cell (DC)-based vaccination can induce antitumor T cell responses in vivo. This clinical pilot study examined feasibility and outcome of DC-based tumor vaccination for patients with advanced pancreatic adenocarcinoma.
Tumor lysate of patients with pancreatic carcinoma was generated by repeated freeze-thaw cycles of surgically obtained tissue specimens. Patients were eligible for DC vaccination after recurrence of pancreatic carcinoma or in a primarily palliative situation. DC were generated from peripheral blood mononuclear cells (PBMC), loaded with autologous tumor lysate, stimulated with TNF-alpha and PGE(2) and injected intradermally. All patients received concomitant chemotherapy with gemcitabine. Disease response was the primary endpoint. Individual immunological responses to DC vaccination were analyzed by T cell-based immunoassays using pre- and post-vaccination samples of non-adherent PBMC.
Twelve patients received DC vaccination and concomitant chemotherapy. One patient developed a partial remission, and two patients remained in stable disease. Median survival was 10.5 months. No severe side effects were observed. Tumor-reactive T cells could be detected prior to vaccination. DC vaccination increased the frequency of tumor-reactive cells in all patients tested; however, the degree of this increase varied. To quantify the presence of tumor-reactive T cells, stimulatory indices (SI) were calculated as the ratio of proliferation-inducing capacity of lysate-loaded versus -unloaded DC. The patient with longest overall survival of 56 months had a high SI of 6.49, indicating that the presence of a pre-vaccination antitumor T cell response might be associated with prolonged survival. Five patients survived 1 year or more.
DC-based vaccination can stimulate an antitumoral T cell response in patients with advanced or recurrent pancreatic carcinoma receiving concomitant gemcitabine treatment.

Ten healthy subjects in each of four metabolizer groups were randomized to a clopidogrel regimen of a 300-mg loading dose (LD) and a 75-mg/day maintenance dose (MD) for 4 days followed by 600-mg LD and 150 mg/day MD, or vice versa. The exposure levels of clopidogrel's active metabolite H4 (clopi-H4) in PMs were 71% lower on the 75-mg/day regimen and 64% lower on the 150-mg/day regimen than the corresponding exposure levels in extensive metabolizers (EMs). In PMs, the maximal platelet aggregation (MPA) induced by adenosine diphosphate (ADP) 5 mu mol/l was 10.5% lower on the 75-mg/day regimen and 7.9% lower on the 150-mg/day regimen than the corresponding values in EMs. PMs who were on the clopidogrel regimen of 600-mg LD/150 mg/day MD showed clopi-H4 exposure and MPA levels similar to those in EMs who were on the regimen of 300-mg LD/75 mg/day MD. In a pooled analysis evaluating CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP3A5, CYP2D6, ABCB1, and P2RY12 polymorphisms (N = 396 healthy subjects), only CYP2C19 had a significant impact on antiplatelet response. In healthy CYP2C19 PMs, a clopidogrel regimen of 600-mg LD/150 mg/day MD largely overcomes diminished clopi-H4 exposure and antiplatelet response, as assessed by MPA levels.

AB Aim A few studies have specifically addressed faecal incontinence (FI) in men. We sought to describe patterns of male FI, assess treatment outcome and compare some aspects of FI between men and women, including quality of life.
Method Prospectively recorded data on 85 consecutive male patients evaluated for FI at our pelvic floor centre in 2004 and 2005 were reviewed and compared with a cohort of 408 female patients. Treatment outcome in men was assessed by questionnaire.
Results The aetiology of FI could be determined in 61 (72%) men and was most commonly related to anal surgery (n = 23), prostate cancer therapy (n = 9) and spinal injury (n = 9). Eight patients had idiopathic soiling only. Mean age, Fecal Incontinence Severity Index (FISI) and quality of life scores were similar between men and women. Maximal mean resting pressure (MRP) and squeeze pressure (MSP) were on average higher in men than in women [MRP 56.9 (26.2) vs 40 (20.4) mmHg; P < 0.0001]; [MSP 98.1 (67.3) vs 39.4 (28.5) mmHg; P < 0.0001]. Sphincter defects involved the external sphincter less often in men (35 vs 70%, P = 0.004). Differences in faecal incontinence quality of life (FIQL) and SF-36 scores between men and women were minimal. After a median follow up of 2 years, complete resolution of symptoms was reported in 17% and improvement of symptoms in another 48% of men.
Conclusion Although physiological and anatomical features of FI differ between men and women, its severity and impact on quality of life are similar. External sphincter defects are less common in men; hence, direct sphincter repair is less frequently an option. Evaluation and treatment improves symptoms in more than half of male patients.

AB For several decades, lipid biologists have investigated how sphingolipids contribute to physiology, cell biology, and cell fate. Foremost among these discoveries is the finding that the bioactive sphingolipids ceramide, sphingosine, and sphingosine-1-phosphate (S1P) have diverse and often opposing effects on cell fate. Interestingly, these bioactive sphingolipids can be interconverted by just a few enzymatic reactions. Therefore, much attention has been paid to the enzymes which govern these reactions with a disproportionate amount of focus on the enzyme sphingosine kinase 1 (SK1). Several studies have found that tissue expression of SK1 correlates with cancer stage, chemotherapy response, and tumor aggressiveness. In addition, overexpression of SK1 in multiple cancer cell lines increases their resistance to chemotherapy, promotes proliferation, allows for anchorage independent growth, and increases local angiogenesis. Inhibition of SK1 using either pharmacological inhibitors or by crossing SK1 null mice has shown promise in many xenograft models of cancer, as well as several genetic and chemically induced mouse models of carcinogenesis. Here, we review the majority of the evidence that suggests SK1 is a promising target for the prevention and/or treatment of various cancers. Also, we strongly advocate for further research into basic mechanisms of bioactive sphingolipid signaling, and an increased focus on the efficacy of SK inhibitors in non-xenograft models of cancer progression.

AB Fibroblast growth factor (FGF21) plays an important role in regulating hepatic oxidation of fatty acids and gluconeogenesis in response to fasting and during consumption of a ketogenic diet. However, the metabolic pathways through which FGF21 regulates hepatic function are not well defined. To identify the effects of FGF21 on the liver in vivo, we administered FGF21 to mice and analyzed acute effects on signaling and gene expression. We found that FGF21 acts directly on the liver to stimulate phosphorylation of fibroblast growth factor receptor substrate 2 and ERK1/2. Acute FGF21 treatment induced hepatic expression of key regulators of gluconeogenesis, lipid metabolism, and ketogenesis including glucose-6-phosphatase, phosphoenol pyruvate carboxykinase, 3-hydroxybutyrate dehydrogenase type 1, and carnitine palmitoyltransferase 1 alpha. In addition, injection of FGF21 was associated with decreased circulating insulin and free fatty acid levels. FGF21 treatment induced mRNA and protein expression of peroxisome proliferator-activated receptor-gamma coactivator (PGC-1 alpha), suggesting that PGC-1 alpha may play a role in regulating FGF21 action. However, studies using mice with liver-specific ablation of PGC-1 alpha revealed the same regulation of gluconeogenic gene expression by FGF21 as seen in wild-type mice, indicating that PGC-1 alpha is not necessary for the effect of FGF21 on glucose metabolism. These data demonstrate that FGF21 acts directly on the liver to modulate hepatic metabolism. The direct effects we examined are not dependent on PGC-1 alpha. In addition, FGF21 treatment is associated with decreased serum insulin levels that my affect hepatic function. (Endocrinology 152: 2996-3004, 2011)

AB BACKGROUND: The FMR1 premutation is associated with overt primary ovarian insufficiency (POI). However, its prevalence in women with occult POI (i.e. menstrual cycles, but impaired ovarian response) has not been examined. We hypothesized that both the FMR1 premutation and intermediate allele is more frequent in infertile women with occult POI than in controls, and that a repeat length cutoff might predict occult POI.
METHODS: All subjects were menstruating women,42 years old and with no family history of unexplained mental retardation, autism or fragile X syndrome. Cases had occult POI defined by elevated FSH or poor response to gonadotrophin therapy (n = 535). Control subjects (n = 521) had infertility from other causes or were oocyte donors. Prevalence of the FMR1 premutation and intermediate alleles was examined and allele length was compared between controls and women with occult POI.
RESULTS: The frequency of the premutation (7/535 versus 1/521; P < 0.05) and intermediate alleles (17/535 versus 7/521; P < 0.05) was higher in women with occult POI than in controls. The allele with the greatest number of CGG repeats was longer in women with occult POI compared with controls (32.7 +/- 7.1 versus 31.6 +/- 4.3; P < 0.01). A receiver operating characteristic curve examining repeat length as a test for occult POI had an area of 0.56 +/- 0.02 (P < 0.01). A repeat cutoff of 45 had a specificity of 98%, but a sensitivity of only 5% to identify occult POI. The positive predictive value was only 21% for a fertility population that has similar to 22% of its patients with occult POI.
CONCLUSIONS: The data suggest that FMR1 premutations and intermediate alleles are increased in women with occult POI. Thus, FMR1 testing should be performed in these women as some will have fragile X-associated POI. Although the FMR1 repeat lengths were longer in women with occult POI, the data do not support the use of a repeat length cutoff to predict occult POI.

AB OBJECTIVE. To evaluate whether longitudinal insurer claims data allow reliable identification of elevated hospital surgical site infection (SSI) rates.
DESIGN. We conducted a retrospective cohort study of Medicare beneficiaries who underwent coronary artery bypass grafting (CABG) in US hospitals performing at least 80 procedures in 2005. Hospitals were assigned to deciles by using case mix-adjusted probabilities of having an SSI-related inpatient or outpatient claim code within 60 days of surgery. We then reviewed medical records of randomly selected patients to assess whether chart-confirmed SSI risk was higher in hospitals in the worst deciles compared with the best deciles.
PARTICIPANTS. Fee-for-service Medicare beneficiaries who underwent CABG in these hospitals in 2005.
RESULTS. We evaluated 114,673 patients who underwent CABG in 671 hospitals. In the best decile, 7.8% (958/12,307) of patients had an SSI-related code, compared with 24.8% (2,747/11,068) in the worst decile (P < .001). Medical record review confirmed SSI in 40% (388/980) of those with SSI-related codes. In the best decile, the chart-confirmed annual SSI rate was 3.2%, compared with 9.4% in the worst decile, with an adjusted odds ratio of SSI of 2.7 (confidence interval, 2.2-3.3; P < .001) for CABG performed in a worst-decile hospital compared with a best-decile hospital.
CONCLUSIONS. Claims data can identify groups of hospitals with unusually high or low post-CABG SSI rates. Assessment of claims is more reproducible and efficient than current surveillance methods. This example of secondary use of routinely recorded electronic health information to assess quality of care can identify hospitals that may benefit from prevention programs.

AB OBJECTIVES. To determine whether preoperative nasal methicillin-resistant Staphylococcus aureus (MRSA) carriage is a significant predictor of postoperative infections, after accounting for surgical infection risk and surgical prophylaxis.
DESIGN. Retrospective cohort study.
PATIENTS. Veterans Affairs (VA) Boston patients who had nasal MRSA polymerase chain reaction screening performed in the 31 days before clean or clean contaminated surgery in 2008-2009.
METHODS. Postoperative MRSA clinical cultures and infections, total surgical site infections (SSIs), and surgical prophylaxis data were abstracted from administrative databases. MRSA infections were confirmed via chart review. Multivariate analysis of risk factors for each outcome was conducted using Poisson regression. SSI risk index was calculated for a subset of 1,551 patients assessed by the VA National Surgical Quality Improvement Program.
RESULTS. Among 4,238 eligible patients, 279 (6.6%) were positive for preoperative nasal MRSA. Postoperative MRSA clinical cultures and infections, including MRSA SSIs, were each significantly increased in patients with preoperative nasal MRSA. After adjustment for surgery type, vancomycin prophylaxis, chlorhexidine/alcohol surgical skin preparation, and SSI risk index, preoperative nasal MRSA remained significantly associated with postoperative MRSA cultures (relative risk [RR], 8.81; 95% confidence interval [CI], 3.01-25.82) and infections (RR, 8.46; 95% CI, 1.70-42.04). Vancomycin prophylaxis was associated with an increased risk of total SSI in those negative for nasal MRSA (RR, 4.34; 95% CI, 2.19-8.57) but not in patients positive for nasal MRSA.
CONCLUSIONS. In our population, preoperative nasal MRSA colonization was independently associated with MRSA clinical cultures and infections in the postoperative period. Vancomycin prophylaxis increased the risk of total SSI in nasal MRSA-negative patients. Infect Control Hosp Epidemiol 2011; 32(8): 791-796

AB Purpose: The objectives of this study were (1) to examine whether the association between childhood family conflict and the risk of substance use disorders (SUDs) in adolescence differs by gender, and (2) to determine whether anxious/depressive symptoms and conduct problems explain this association among adolescent males and females.
Methods: Data were obtained from 1,421 children aged 10-16 years at the time of enrollment in the Project on Human Development in Chicago Neighborhoods. We assessed gender differences in the association between childhood family conflict and adolescent SUDs by fitting a logistic regression model that included the interaction of gender and family conflict. We also investigated whether conduct problems and anxious/depressive symptoms explained the association between family conflict and SUDs differently for males and females through gender-specific mediation analyses.
Results: The association between childhood family conflict and SUDs in adolescence differed by gender (p = .04). Family conflict was significantly associated with SUDs among females (OR: 1.61; CI: 1.20-2.15), but not among males (OR: 1.00; CI:.76-1.32). The elevated risk of SUDs among females exposed to family conflict was partly explained by girls' conduct problems, but not by anxious/depressive symptoms.
Conclusions: Females living in families with elevated levels of conflict were more likely to engage in acting out behaviors, which was associated with the development of SUDs. Future epidemiologic research is needed to help determine when this exposure is most problematic with respect to subsequent mental health outcomes and the most crucial time to intervene.

TI Neighborhood Environment and Health Status and Mortality Among Veterans
SO JOURNAL OF GENERAL INTERNAL MEDICINE

PRIMER; DEATH
AB BACKGROUND: The VHA is the largest integrated US health system and is increasingly moving care into the communities where veterans reside. Veterans who utilize the VA for their care have worse health status than the general population. However, there is limited evidence about the association of neighborhood environment and health outcomes among veterans.
OBJECTIVES: The primary aim of this study is to assess the relative contribution of neighborhood environment, health system, and individual characteristics to health status and mortality of veterans.
METHODS: Information on personal socio-economic indicators, existing medical conditions and health status were obtained from baseline data from a multi-site, randomized trial of primary care patients (n = 15,889). The physical component scale (PCS) and mental component scale (MCS) summarized health status. Census tracts were used as proxies for neighborhoods. A summary score based on census tract data characterized the neighborhood socio-economic environment and walkability. Data were analyzed with multilevel hierarchical models. Analyses of health status were cross-sectional. Mortality analyses were longitudinal as participants were followed for an average of 722.5 days to ascertain vital status.
RESULTS: Neighborhood SES was associated with PCS and MCS scores, controlling for individual socio-economic status, self-reported co-morbid disease, smoking status, and health care access. In the lowest versus highest quartiles of neighborhood SES, adjusted PCS scores were 34.4 vs. 35.4 (p < 0.05) and adjusted MCS scores were 46.2 versus 47.0 (p < 0.05). PCS score was also significantly associated with neighborhood walkability (p < 0.05). Mortality was lower for veterans living in neighborhoods with the highest decile neighborhood SES (HR 0.78, highest vs. lowest decile 95% CI 0.63, 0.97).
CONCLUSIONS: Veterans living in lower SES neighborhoods have poorer health status and a higher risk of mortality, independent of individual characteristics and health care access. Neighborhood walkability was associated with higher PCS scores.

AB BACKGROUND: While victims of intimate partner violence (IPV) present to health care settings for a variety of complaints; rates and predictors of case identification and intervention are unknown.
OBJECTIVE: Examine emergency department (ED) case finding and response within a known population of abused women.
DESIGN: Retrospective longitudinal cohort study.
SUBJECTS: Police-involved female victims of IPV in a semi-rural Midwestern county.
MAIN MEASURES: We linked police, prosecutor, and medical record data to examine characteristics of ED identification and response from 1999-2002; bivariate analyses and logistic regression analyses accounted for the nesting of subjects' with multiple visits.
RESULTS: IPV victims (N = 993) generated 3,426 IPV-related police incidents (mean 3.61, median 3, range 1-17) over the 4-year study period; 785 (79%) generated 4,306 ED visits (mean 7.17, median 5, range 1-87), which occurred after the date of a documented IPV assault. Only 384 (9%) ED visits occurred within a week of a police-reported IPV incident. IPV identification in the ED was associated with higher violence severity, being childless and underinsured, more police incidents (mean: 4.2 vs 3.3), and more ED visits (mean: 10.6 vs 5.5) over the 4 years. The majority of ED visits occurring after a documented IPV incident were for medical complaints (3,378, 78.4%), and 72% of this cohort were never identified as victims of abuse. IPV identification was associated with the day of a police incident, transportation by police, self-disclosure of "domestic assault," and chart documentation of mental health and substance abuse issues. When IPV was identified, ED staff provided legally useful documentation (86%), police contact (50%), and social worker involvement (45%), but only assessed safety in 33% of the women and referred them to victim services 25% of the time.
CONCLUSION: The majority of police-identified IPV victims frequently use the ED for health care, but are unlikely to be identified or receive any intervention in that setting.

AB Follicular helper T (TFH) cells are critical for germinal center ( GC) formation. The processes that drive their generation and effector potential remain unclear. In this study, we define requirements for MHC class II APCs in murine TFH cell formation by either transiently ablating or restricting Ag presentation to dendritic cells (DCs). We find that cognate interactions with DCs are necessary and sufficient to prime CD4(+) T cells toward a CXCR5(+)ICOS(+)Bcl6(+) T-FH cell intermediate. However, in the absence of additional APCs, these TFH cells fail to produce IL-21. Furthermore, in vitro priming of naive T cells by B cells engenders optimal production of IL-21, which induces a GC B cell transcriptional profile. These results support a multistep model for effector TFH cell priming and GC initiation, in which DCs are necessary and sufficient to induce a TFH cell intermediate that requires additional interactions with distinct APCs for full effector function.

AB Programmed death-1 ligand 1 (PD-L1) is a coinhibitory molecule that negatively regulates multiple tolerance checkpoints. In the NOD mouse model, PD-L1 regulates the development of diabetes. PD-L1 has two binding partners, programmed death-1 and B7-1, but the significance of the PD-L1:B7-1 interaction in regulating self-reactive T cell responses is not yet clear. To investigate this issue in NOD mice, we have compared the effects of two anti-PD-L1 Abs that have different blocking activities. Anti-PD-L1 mAb 10F.2H11 sterically and functionally blocks only PD-L1: B7-1 interactions, whereas anti-PD-L1 mAb 10F.9G2 blocks both PD-L1: B7-1 and PD-L1: programmed death-1 interactions. Both Abs had potent, yet distinct effects in accelerating diabetes in NOD mice: the single-blocker 10F.2H11 mAb was more effective at precipitating diabetes in older (13-wk-old) than in younger (6- to 7-wk-old) mice, whereas the dual-blocker 10F.9G2 mAb rapidly induced diabetes in NOD mice of both ages. Similarly, 10F.2H11 accelerated diabetes in recipients of T cells from diabetic, but not prediabetic mice, whereas 10F.9G2 was effective in both settings. Both anti-PD-L1 mAbs precipitated diabetes in adoptive transfer models of CD4(+) and CD8(+) T cell-driven diabetes. Taken together, these data demonstrate that the PD-L1: B7-1 pathway inhibits potentially pathogenic self-reactive effector CD4(+) and CD8(+) T cell responses in vivo, and suggest that the immunoinhibitory functions of this pathway may be particularly important during the later phases of diabetogenesis.

TI The Novel Costimulatory Programmed Death Ligand 1/B7.1 Pathway Is
Functional in Inhibiting Alloimmune Responses In Vivo

AB The programmed death ligand 1 (PDL1)/programmed death 1 (PD1) costimulatory pathway plays an important role in the inhibition of alloimmune responses as well as in the induction and maintenance of peripheral tolerance. It has been demonstrated recently that PDL1 also can bind B7.1 to inhibit T cell responses in vitro. Using the bm12 into B6 heart transplant model, we investigated the functional significance of this interaction in alloimmune responses in vivo. PD1 blockade unlike PDL1 blockade failed to accelerate bm12 allograft rejection, suggesting a role for an additional binding partner for PDL1 other than PD1 in transplant rejection. PDL1 blockade was able to accelerate allograft rejection in B7.2-deficient recipients but not B7.1-deficient recipients, indicating that PDL1 interaction with B7.1 was important in inhibiting rejection. Administration of the novel 2H11 anti-PDL1 mAb, which only blocks the PDL1-B7.1 interaction, aggravated chronic injury of bm12 allografts in B6 recipients. Aggravated chronic injury was associated with an increased frequency of alloreactive IFN-gamma-, IL-4-, and IL-6-producing splenocytes and a decreased percentage of regulatory T cells in the recipients. Using an in vitro cell culture assay, blockade of the interaction of PDL1 on dendritic cells with B7.1 on T cells increased IFN-gamma production from alloreactive CD4(+) T cells, whereas blockade of dendritic cell B7.1 interaction with T cell PDL1 did not. These data indicate that PDL1 interaction with B7.1 plays an important role in the inhibition of alloimmune responses in vivo and suggests a dominant direction for PDL1 and B7.1 interaction.

AB Recent studies in cell lines and genetically engineered mice have demonstrated that cytosolic dsDNA could activate dendritic cells (DCs) to become effector APCs. Recognition of DNA might be a major factor in antimicrobial immune responses against cytosolic pathogens and also in human autoimmune diseases such as systemic lupus erythematosus. However, the role of cytosolic dsDNA in human DC activation and its effects on effector T and B cells are still elusive. In this study, we demonstrate that intracellular dsDNA is a potent activator of human monocyte-derived DCs as well as primary DCs. Activation by dsDNA depends on NF-kappa B activation, partially on the adaptor molecule IFN-promoter stimulator-1 and the novel cytosolic dsDNA receptor IFI16, but not on the previously recognized dsDNA sentinels absent in melanoma 2, DNA-dependent activator of IFN regulatory factor 3, RNA polymerase III, or high-mobility group boxes. More importantly, we report for the first time, to our knowledge, that human dsDNA-activated DCs, rather than LPS-or inflammatory cytokine mixture-activated DCs, represent the most potent inducers of naive CD4(+) T cells to promote Th1-type cytokine production and generate CD4(+) and CD8(+) cytotoxic T cells. dsDNA-DCs, but not LPS- or mixture-activated DCs, induce B cells to produce complement-fixing IgG1 and IgG3 Abs. We propose that cytosolic dsDNA represents a novel, more effective approach to generate DCs to enhance vaccine effectiveness in reprogramming the adaptive immune system to eradicate infectious agents, autoimmunity, allergy, and cancer.

TI The 57 kb deletion in cystinosis patients extends into TRPV1 causing
dysregulation of transcription in peripheral blood mononuclear cells
SO JOURNAL OF MEDICAL GENETICS
LA English
DT Article
ID NEPHROPATHIC CYSTINOSIS; CTNS MUTATIONS; GENE; MICE; CAPSAICIN; RECEPTOR
AB Background Cystinosis is an autosomal recessive disease characterised by the abnormal accumulation of lysosomal cystine. Mutations in the cystinosin gene (CTNS) represent known causes for the disease. The major cystinosis mutation is a 57 kb deletion on human chromosome 17p13 that removes the majority of CTNS and the entire adjacent gene, CARKL/SHPK.
Objectives In order to identify other genes that may influence the cystinosis pathobiological pathway, peripheral blood mononuclear cells (PBMC) were collected from cystinosis family members, and DNA and RNA extracted.
Results Using whole genome transcriptional profiling, transient receptor potential vanilloid 1 (TRPV1) was found to be differentially expressed in association with cystinosis. This was verified using TaqMan qRT-PCR. There was a 72% reduction in PBMC TRPV1 mRNA levels in cystinosis individuals homozygous for the 57 kb deletion (n = 6) compared to unaffected individuals without the deletion (n = 6) (p = 0.002). TRPV1 is a sensory receptor located on chromosome 17p13, adjacent to CARKL/SHPK. It was ascertained that the 57 kb deletion extends from exon 10 of CTNS, upstream through CARKL/SHPK, to intron 2 of TRPV1, thus deleting the first two non-coding exons.
Conclusion This is the first study to report that the 57 kb deletion extends into the TRPV1 gene causing dysregulation of transcription in PBMC isolated from cystinosis patients.

AB Although commercial tests are approved for detection of HIV-1 plasma viral loads >= 20 copies per milliliter (ml), only one specialized research assay has been reported to detect plasma viral loads as low as 1 copy/ml. This manuscript describes a method of concentrating HIV-1 virions from up to 30 ml of plasma, which can be combined with a commercial viral load test to create a widely available, reproducible assay for quantifying plasma HIV RNA levels less than 1 copy/ml. Using this pre-analytically modified assay, samples with a known level of 0.5 copy/ml were detected in 8 of 12 replicates (mean 0.47 copy/ml; 95% confidence interval (CI) 0.14-0.81 copy/ml) and samples with a known level of 1.0 copy/ml were detected in 13 of 13 replicates (mean 1.96 copy/ml; 95% CI 1.42-2.50 copy/ml). By concentrating virus from 30 ml of plasma, HIV RNA could be measured in 16 of 19 samples (84%) from 12 of 12 subjects (mean 2.77 copy/ml; 95% CI 0.86-4.68 copy/ml). The measured viral load correlated inversely (r = -0.78; p = 0.028) with the total duration of viral suppression (viral load < 40 copies/ml). (C) 2011 Elsevier B.V. All rights reserved.

AB The mammalian tripartite motif protein, TRIM5 alpha, recognizes retroviral capsids entering the cytoplasm and blocks virus infection. Depending on the particular TRIM5 alpha protein and retrovirus, complete disruption of the TRIM5 alpha RING domain decreases virus-restricting activity to various degrees. TRIM5 alpha exhibits RING domain-dependent E3 ubiquitin ligase activity, but the specific role of this activity in viral restriction is unknown. We created a panel of African green monkey TRIM5 alpha (TRIM5 alpha(AGM)) mutants, many of which are specifically altered in RING domain E3 ubiquitin ligase function, and characterized the phenotypes of these mutants with respect to restriction of simian and human immunodeficiency viruses (SIVmac and HIV-1, respectively). TRIM5 alpha(AGM) ubiquitin ligase activity was essential for both the accelerated disassembly of SIV(mac) capsids and the disruption of reverse transcription. The levels of SIV(mac) particulate capsids in the cytosol of target cells expressing the TRIM5 alpha variants strongly correlated with the levels of viral late reverse transcripts. RING-mediated ubiquitylation and B30.2(SPRY) domain-determined capsid binding independently contributed to the potency of SIV(mac) restriction by TRIM5 alpha(AGM). In contrast, TRIM5 alpha proteins attenuated in RING ubiquitin ligase function still accelerated HIV-1 capsid disassembly, inhibited reverse transcription, and blocked infection. Replacement of the helix-4/5 loop in the SIV(mac) capsid with the corresponding region of the HIV-1 capsid diminished the dependence of restriction on TRIM5 alpha RING function. Thus, ubiquitylation mediated by the RING domain of TRIM5 alpha(AGM) is essential for blocking SIVmac infection at the stage of capsid uncoating.

AB Autism spectrum disorder (ASD) and schizophrenia (SCZ) are two common neurodevelopmental syndromes that result from the combined effects of environmental and genetic factors. We set out to test the hypothesis that rare variants in many different genes, including de novo variants, could predispose to these conditions in a fraction of cases. In addition, for both disorders, males are either more significantly or more severely affected than females, which may be explained in part by X-linked genetic factors. Therefore, we directly sequenced 111 X-linked synaptic genes in individuals with ASD (n = 142; 122 males and 20 females) or SCZ (n = 143; 95 males and 48 females). We identified > 200 non-synonymous variants, with an excess of rare damaging variants, which suggest the presence of disease-causing mutations. Truncating mutations in genes encoding the calcium-related protein IL1RAPL1 (already described in Piton et al. Hum Mol Genet 2008) and the monoamine degradation enzyme monoamine oxidase B were found in ASD and SCZ, respectively. Moreover, several promising non-synonymous rare variants were identified in genes encoding proteins involved in regulation of neurite outgrowth and other various synaptic functions (MECP2, TM4SF2/TSPAN7, PPP1R3F, PSMD10, MCF2, SLITRK2, GPRASP2, and OPHN1).

AB Increasingly, human mesenchymal malignancies are being classified by the abnormalities that drive their pathogenesis. Although many of these aberrations are highly prevalent within particular sarcoma subtypes, few are currently targeted therapeutically. Indeed, most subtypes of sarcoma are still treated with traditional therapeutic modalities, and in many cases sarcomas are resistant to adjuvant therapies. In this Review, we discuss the core molecular determinants of sarcomagenesis and emphasize the emerging genomic and functional genetic approaches that, coupled with novel therapeutic strategies, have the potential to transform the care of patients with sarcoma.

AB OBJECTIVE: It is often difficult to distinguish a benign pelvic mass from a malignancy and tools to help referring physician are needed. The purpose of this study was to validate the Risk of Ovarian Malignancy Algorithm in women presenting with a pelvic mass.
METHODS: This was a prospective, multicenter, blinded clinical trial that included women who presented to a gynecologist, a family practitioner, an internist, or a general surgeon with an adnexal mass. Serum HE4 and CA 125 were determined preoperatively. A Risk of Ovarian Malignancy Algorithm score was calculated and classified patients into high-risk and low-risk groups for having a malignancy. The sensitivity, specificity, negative predictive value, and positive predictive value of the Risk of Ovarian Malignancy Algorithm were estimated.
RESULTS: A total of 472 patients were evaluated with 383 women diagnosed with benign disease and 89 women with a malignancy. The incidence of all cancers was 15% and 10% for ovarian cancer. In the postmenopausal group, a sensitivity of 92.3% and a specificity of 76.0% and for the premenopausal group the Risk of Ovarian Malignancy Algorithm had a sensitivity of 100% and specificity of 74.2% for detecting ovarian cancer. When considering all women together, the Risk of Ovarian Malignancy Algorithm had a sensitivity of 93.8%, a specificity of 74.9%, and a negative predictive value of 99.0%.
CONCLUSION: The use of the serum biomarkers HE4 and CA 125 with the Risk of Ovarian Malignancy Algorithm has a high sensitivity for the prediction of ovarian cancer in women with a pelvic mass. These findings support the use of the Risk of Ovarian Malignancy Algorithm as a tool for the triage of women with an adnexal mass to gynecologic oncologists.

AB Methods. We examined skin cancer risk in a cohort of 20 648 patients with RA derived from the Department of Veterans' Affairs (VA) national administrative databases. The cohort was divided into two medication groups: patients treated with non-biologic and TNF-alpha antagonist DMARDs. We defined skin cancer as the first occurrence of an International Classification of Disease, Version 9, Clinical Modification (ICD-9-CM) code for NMSC after initiation of a DMARD. Outcome risk was described using hazard ratios (HRs) with Cox proportional hazards regression for time-to-event analysis and logistic regression. We performed medical record review to validate the diagnosis of NMSC.
Results. Incidence of NMSC was 18.9 and 12.7 per 1000 patient-years in patients on TNF-alpha antagonists and non-biologic DMARDs, respectively. Patients on TNF-alpha antagonists had a higher risk of developing NMSC (HR 1.42; 95% CI 1.24, 1.63). Risk factors for NMSC included older age, male gender, NSAID and glucocorticoid use and a history of prior malignancies. There was substantial agreement between ICD-9-CM diagnosis of NMSC and medical record validation (kappa = 0.61).
Conclusion. TNF-alpha antagonist therapy in veterans with RA may be associated with an increased risk of NMSC, compared with therapy with non-biologic DMARDs. Rheumatologists should carefully screen patients receiving TNF-alpha antagonists for pre-cancerous skin lesions and skin cancer.

AB Methods. Patients with RA and controls were recruited at the University of California, San Francisco (UCSF). Disease activity was evaluated using standard composite indices. Fibrinogen, ESR, serum CRP, acute-phase serum amyloid A and levels of selected cytokines were quantified.
Results. A total of 105 RA patients and 62 controls were studied. Among patients with RA, disease activity ranged from quiescent to highly active disease. Circulating fibrinogen levels were significantly higher in RA than in controls [median (interquartile range) 466 (391-575) vs 367 (309-419) mg/dl, respectively, P < 0.0001]. This difference remained highly statistically significant after adjustment for demographic variables and BMI. Although fibrinogen correlated significantly with clinical measures of disease activity, significantly elevated levels were observed at low levels of activity, even in RA patients with no detectable swollen or tender joints. In multivariable models, similar to 80% of the increased fibrinogen in RA was accounted for by increases in CRP and ESR.
Conclusion. Circulating levels of fibrinogen are elevated in RA and correlated with markers of inflammation, but only modestly correlate with clinical assessments of disease activity. Even RA patients with excellent clinical disease control exhibit elevated levels compared with controls.

DT Review
DE Elderly; Seizures; Epilepsy; Status; Aging; Pathophysiology
AB Acute seizures, epilepsy and status epilepticus have the highest incidences in those over the age of 60 as compared to all other age groups. The most common etiological factors for epilepsy in the elderly are related to cerebrovascular disease. Diagnosing epilepsy in the elderly is challenging because of the subtle manifestations of partial seizures and the presence of age related cognitive difficulties, co-morbid conditions, and medications. Epilepsy treatment in this population is also difficult due to age related changes in pharmacokinetics and pharmacodynamics as well as individual variability. There are considerable gaps of knowledge about the basic pathophysiological mechanisms of recurrent partial onset seizures in the aged brain. This article critically reviews pathophysiological considerations that might impact the scientific approach of experimental research modeling of unprovoked seizures and epilepsy in elderly individuals, and the limited experimental epilepsy research on aged models.

AB Objective: Red cell distribution width is a predictor of mortality in the general population. The prevalence of increased red cell distribution width and its significance in the intensive care unit are unknown. The objective of this study was to investigate the association between red cell distribution width at the initiation of critical care and all cause mortality.
Design: Multicenter observational study.
Setting: Two tertiary academic hospitals in Boston, MA.
Patients: A total of 51,413 patients, aged >= 18 yrs, who received critical care between 1997 and 2007.
Interventions: None.
Measurements and Main Results: The exposure of interest was red cell distribution width as a predictor of mortality in the general population. The prevalence of increased red cell distribution width and its significance in the intensive care unit are unknown and categorized a priori in quintiles as <= 13.3%, 13.3% to 14.0%, 14.0% to 14.7%, 14.7% to 15.8%, and >15.8%. Logistic regression examined death by days 30, 90, and 365 postcritical care initiation, inhospital mortality, and bloodstream infection. Adjusted odds ratios were estimated by multivariable logistic regression models. Adjustment included age, sex, race, Deyo-Charlson index, coronary artery bypass grafting, myocardial infarction, congestive heart failure, hematocrit, white blood cell count, mean corpuscular volume, blood urea nitrogen, red blood cell transfusion, sepsis, and creatinine. Red cell distribution width was a particularly strong predictor of all-cause mortality 30 days after critical care initiation with a significant risk gradient across red cell distribution width quintiles after multivariable adjustment: red cell distribution width 13.3% to 14.0% (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.08-1.30; p <.001); red cell distribution width 14.0% to 14.7% (OR, 1.28; 95% CI, 1.16-1.42; p <.001); red cell distribution width 14.7% to 15.8% (OR, 1.69; 95% CI, 1.52-1.86; p <.001); red cell distribution width >15.8% (OR, 2.61; 95% CI, 2.37-2.86; p <.001), all relative to patients with red cell distribution width <= 13.3%. Similar significant robust associations postmultivariable adjustments are seen with death by days 90 and 365 postcritical care initiation as well as inhospital mortality. In a subanalysis of patients with blood cultures drawn (n = 18,525), red cell distribution width at critical care initiation was associated with the risk of bloodstream infection and remained significant after multivariable adjustment. The adjusted risk of bloodstream infection was 1.40- and 1.44-fold higher in patients with red cell distribution width values in the 14.7% to 15.8% and >15.8% quintiles, respectively, compared with those with red cell distribution width <= 13.3%. Estimating the receiver operating characteristic area under the curve shows that red cell distribution width has moderate discriminative power for 30-day mortality (area under the curve = 0.67).
Conclusion: Red cell distribution width is a robust predictor of the risk of all-cause patient mortality and bloodstream infection in the critically ill. Red cell distribution width is commonly measured, inexpensive, and widely available and may reflect overall inflammation, oxidative stress, or arterial underfilling in the critically ill.

DT Article
DE Peer review; performance improvement; quality assessment; quality
improvement; RADPEER (TM)
ID DIAGNOSTIC-PROCEDURES; ACCURACY
AB RADPEER (TM) is a quality assessment and improvement product developed and marketed by the ACR. Although the program has been available since 2002 and the scoring system was revised in 2009, the ACR allows considerable flexibility in its implementation. Although that flexibility supports the local needs of radiology groups using the program, it also may lead to suboptimal implementation of the program and may limit the usefulness of the data obtained. The authors, who are members of the ACR RADPEER Committee, provide 11 specific suggestions to optimize the performance of RADPEER and suggest opportunities for future improvement of the program.

Atherosclerosis

AB The vascular response to injury is a well-orchestrated inflammatory response triggered by the accumulation of macrophages within the vessel wall leading to an accumulation of lipid-laden intra-luminal plaque, smooth muscle cell proliferation and progressive narrowing of the vessel lumen. The formation of such vulnerable plaques prone to rupture underlies the majority of cases of acute myocardial infarction. The complex molecular and cellular inflammatory cascade is orchestrated by the recruitment of T lymphocytes and macrophages and their paracrine effects on endothelial and smooth muscle cells. (1)
Molecular imaging in atherosclerosis has evolved into an important clinical and research tool that allows in vivo visualization of inflammation and other biological processes. Several recent examples demonstrate the ability to detect high-risk plaques in patients, and assess the effects of pharmacotherapeutics in atherosclerosis. (4) While a number of molecular imaging approaches (in particular MRI and PET) can image biological aspects of large vessels such as the carotid arteries, scant options exist for imaging of coronary arteries. (2) The advent of high-resolution optical imaging strategies, in particular near-infrared fluorescence (NIRF), coupled with activatable fluorescent probes, have enhanced sensitivity and led to the development of new intravascular strategies to improve biological imaging of human coronary atherosclerosis.
Near infrared fluorescence (NIRF) molecular imaging utilizes excitation light with a defined band width (650-900 nm) as a source of photons that, when delivered to an optical contrast agent or fluorescent probe, emits fluorescence in the NIR window that can be detected using an appropriate emission filter and a high sensitivity charge-coupled camera. As opposed to visible light, NIR light penetrates deeply into tissue, is markedly less attenuated by endogenous photon absorbers such as hemoglobin, lipid and water, and enables high target-to-background ratios due to reduced autofluorescence in the NIR window. Imaging within the NIR 'window' can substantially improve the potential for in vivo imaging. (2,5)
Inflammatory cysteine proteases have been well studied using activatable NIRF probes(10), and play important roles in atherogenesis. Via degradation of the extracellular matrix, cysteine proteases contribute importantly to the progression and complications of atherosclerosis(8). In particular, the cysteine protease, cathepsin B, is highly expressed and colocalizes with macrophages in experimental murine, rabbit, and human atheromata. (3,6,7) In addition, cathepsin B activity in plaques can be sensed in vivo utilizing a previously described 1-D intravascular near-infrared fluorescence technology(6), in conjunction with an injectable nanosensor agent that consists of a poly-lysine polymer backbone derivatized with multiple NIR fluorochromes (VM110/Prosense750, ex/em 750/780nm, VisEn Medical, Woburn, MA) that results in strong intramolecular quenching at baseline. (10) Following targeted enzymatic cleavage by cysteine proteases such as cathepsin B (known to colocalize with plaque macrophages), the fluorochromes separate, resulting in substantial amplification of the NIRF signal. Intravascular detection of NIR fluorescence signal by the utilized novel 2D intravascular NIRF catheter now enables high-resolution, geometrically accurate in vivo detection of cathepsin B activity in inflamed plaque.
In vivo molecular imaging of atherosclerosis using catheter-based 2D NIRF imaging, as opposed to a prior 1-D spectroscopic approach, (6) is a novel and promising tool that utilizes augmented protease activity in macrophage-rich plaque to detect vascular inflammation. (11,12) The following research protocol describes the use of an intravascular 2-dimensional NIRF catheter to image and characterize plaque structure utilizing key aspects of plaque biology. It is a translatable platform that when integrated with existing clinical imaging technologies including angiography and intravascular ultrasound (IVUS), offers a unique and novel integrated multimodal molecular imaging technique that distinguishes inflammatory atheromata, and allows detection of intravascular NIRF signals in human-sized coronary arteries.

AB Vascular disease is a leading cause of morbidity and mortality worldwide. Current vascular therapeutic interventions directed at diseased vessels are restricted in long-term efficacy by the development of intimal hyperplasia and the reformation of flow-limiting disease. The vascular injury and inflammation that ensues from the intervention, especially in the setting of an existing atherosclerotic vascular disease, results in further endothelial dysfunction and subsequent smooth muscle cell proliferation and migration. Although the etiology of intimal hyperplasia is multifactorial, impaired nitric oxide (NO) signaling has been implicated. The vasoprotective properties of NO have been intensely studied, and many investigations have focused on harnessing this biological system for therapeutic benefit. Continued studies investigate the role of impaired NO signaling via the classical arginine/NO synthase (NOS)/NO pathway in the setting of intimal hyperplasia. Furthermore, the possible protective effects of nitrate and nitrite-generated NO via non-NOS-mediated pathways to limit vascular injury have been recently appreciated and will likely prove to be an important vasoregulatory and vasoprotective signaling pathway.

AB Oxidative damage affects protein structure and function. Progressive accumulation of oxidized proteins is considered a putative mechanism of aging; however, empirical evidence supporting their role in aging is inconsistent. This inconsistency may reflect a failure to distinguish damage to particular cellular compartments. We found a significant reduction of protein carbonyls in the insoluble, but not in the soluble, fraction of liver tissues of long-lived compared with their short-lived counterpart. Of cellular components analyzed, only nuclear protein carbonyl level was uniformly reduced in long-lived compared with short-lived animals. This observation suggests that attenuated accumulation of protein carbonyls in the nucleus, where they can affect multiple aspects of gene expression and DNA repair, might contribute to the longevity in mammalian species.

AB The Hedgehog (Hh-) signaling pathway is a key developmental pathway which gets reactivated in many human tumors, and smoothened (Smo) antagonists are emerging as novel agents for the treatment of malignancies dependent on the Hh-pathway, with the most advanced compounds demonstrating encouraging results in initial clinical trials. A novel series of potent bicyclic hydantoin Smo antagonists was reported in the preceding article, these have been resolved, and optimized to identify potent homochiral derivatives with clean off-target profiles and good pharmacokinetic properties in preclinical species. While showing in vivo efficacy in mouse allograft models, unsubstituted bicyclic tetrahydroimidazo[1,5-a]pyrazine-1,3(2H,5H)-diones were shown to epimerize in plasma. Alkylation of the C-8 position blocks this epimerization, resulting in the identification of MK-5710 (47) which was selected for further development. (C) 2011 Elsevier Ltd. All rights reserved.

AB We describe a set of web-based calculators, available at http://www.CancerMath.net, which estimate the risk of breast carcinoma death, the reduction in life expectancy, and the impact of various adjuvant treatment choices. The published SNAP method of the binary biological model of cancer metastasis uses information on tumor size, nodal status, and other prognostic factors to accurately estimate of breast cancer lethality at 15 years after diagnosis. By combining these 15-year lethality estimates with data on the breast cancer hazard function, breast cancer lethality can be estimated at each of the 15 years after diagnosis. A web-based calculator was then created to visualize the estimated lethality with and without a range of adjuvant therapy options at any of the 15 years after diagnosis, and enable conditional survival calculations. NIH population data was used to estimate non-breast-cancer chance of death. The accuracy of the calculators was tested against two large breast carcinoma datasets: 7,907 patients seen at two academic hospitals and 362,491 patients from the SEER national dataset. The calculators were found to be highly accurate and specific, as seen by their capacity for stratifying patients into groups differing by as little as a 2% risk of death, and accurately accounting for nodal status, histology, grade, age, and hormone receptor status. Our breast carcinoma calculators provide accurate and useful estimates of the risk of death, which can aid in analysis of the various adjuvant therapy options available to each patient.

No differences in baseline characteristics, and post-induction categorical responses between cohorts were observed. The median rituximab infusions during induction was 6 for both cohorts; and 8 over a 2-year period for patients receiving M-Rituximab. Categorical responses improved in 16/162 (10%) of observed, and 36/86 (41.8%) of M-Rituximab patients respectively, following induction therapy (P < 0 0001). Both progression-free (56.3 vs. 28.6 months; P = 0.0001) and overall survival (Not reached versus 116 months; P = 0.0095) were longer in patients who received M-Rituximab. Improved progression-free survival was evident despite previous treatment status, induction with rituximab alone or in combination therapy (P <= 0.0001). Best serum IgM response was lower (P < 0.0001), and haematocrit higher (P = 0.001) for patients receiving M-Rituximab. Among patients receiving M-Rituximab, an increased number of infectious events were observed, but were mainly <= grade 2 (P = 0.008). The findings of this observational study suggest improved clinical outcomes following M-Rituximab in WM patients who respond to induction with a rituximab-containing regimen. Prospective studies aimed at clarifying the role of M-Rituximab therapy in WM patients are needed to confirm these findings.

AB Anxiety is shared by patients and family members (FMs) and can increase throughout the FMs waiting during invasive cardiac procedures (ICP). The purpose of this study was to measure the effects of an informational report (IR) and a postprocedure visit (PPV), on the anxiety of waiting FMs. There were 151 FMs assigned to 3 groups; Group 1 (50 FMs: standard of care [SOC]), Group 2 (50 FMs: SOC + IR), and Group 3 (51 FMs: SOC + IR + PPV). Pre/postvariables measured were: blood pressure (BP), heart rate (HR), skin temperature (ST), and anxiety. When comparing the BP, HR, ST, and anxiety there were no differences between groups with either SOC or IR. There was a significant reduction in anxiety, from baseline to the PPV in Group 3 (F = 10.1; p < .000). A PPV had an impact on FMs and a PPV should be incorporated as a nursing intervention during ICP.

AB Lowering blood pressure may confer a benefit to diabetic microvascular complications comparable with glycemic control. Hypertension is causally related to kidney outcomes and is a risk factor for the development of diabetic retinopathy. The prevalence of hypertension increases as kidney disease progresses, so that it coexists with diabetes in up to 80% of those with overt nephropathy. A significant number of patients have hypertension or rising blood pressures in earlier stages, or even before microvascular complications appear. Because microalbuminuria markedly increases the risk of overt nephropathy as well as of cardiovascular complications, primary prevention (i.e., preventing or delaying the onset of microalbuminuria) continues to be explored, predominantly through use of renin-angiotensin blockade. Available data reviewed suggest that primary prevention through blood pressure reduction is more likely to benefit select groups (those with hypertension, cardiovascular risks, or old age). This review discusses the relationship between hypertension, diabetes, and kidney disease, the rationale for primary prevention, and the data that led to that conclusion.

AB The number of people with diabetic kidney disease continues to increase worldwide despite current treatments. Of the pathophysiologic mechanisms that have been identified in the development and progression of diabetic nephropathy, oxidative stress (more accurately described as increased levels of reactive oxygen species; ROS) is of major importance. The increase in ROS is due to both increased production and to decreased and/or inadequate antioxidant function. To date, human clinical trials with antioxidants have not been shown to be effective. This is likely due, at least in part, to the lack of specificity of current agents. Recent research has determined both major sources of high glucose-induced cellular ROS production as well as high glucose-induced changes in antioxidant function. Treatments targeted at one or more of the specific diabetes-induced alterations in the regulation of ROS levels will likely lead to effective treatments that prevent the development and progression of diabetic kidney disease.

LA English
DT Article
DE androgen deficiency; hypogonadism; testosterone; varicocele;
varicocelectomy
ID PLASMA TESTOSTERONE; INFERTILE MEN; PARAMETERS; FERTILITY; IMPROVEMENT
AB Purpose of review
The increased risk of infertility in men with varicocele is well established. Varicocelectomy has been shown to improve semen parameters and increase pregnancy rates. Yet varicocele pathophysiology is poorly understood and potential implications for testosterone production are less clear. Evidence suggests that varicocele may result in lower serum testosterone levels and that varicocelectomy may, in turn, correct this deficit.
Recent findings
Several studies published in the past 18 months have assessed the effect of varicocele and varicocelectomy on serum testosterone levels. These include data gathered from two rat models of varicocele induction and outcomes after repair. Of additional interest is a study of serum testosterone levels in men after varicocelectomy, the first of its kind to stratify data by patient age and to address whether varicocele repair is effective in improving testosterone levels in older men.
Summary
Definitive statements regarding varicocele, varicocelectomy, and testosterone are difficult to make given the frequent absence of control groups and lack of sample group consistency. Despite this, recent well done animal and human studies suggest an adverse effect of varicocele on testosterone and a potential benefit of varicocele repair. Further controlled studies examining testosterone as a primary data point are required.

AB Purpose of review
The bidirectional exchange of cells, both mature and progenitor types, at the maternal-fetal interface is a common feature of mammalian reproduction. The presence of semiallogeneic cells in a host can have significant immunological effects on transplantation tolerance and rejection. Here, we review recent advances in this area.
Recent findings
Maternal microchimerism (MMc) in blood and various organs was found to be directly correlated with noninherited maternal antigen (NIMA)-specific CD4(+) regulatory T cells (Tregs), in F(1) backcross mice. In humans, MMc induced NIMA-specific FoxP3(+) CD4 Tregs in lymph nodes and spleen of fetuses. Tolerance to NIMA(+) allografts could be predicted in mice by measuring levels of the NIMA-specific Tregs in offspring before transplantation. On the contrary, fetal microchimerism (FMc) in multiparous female mice was largely confined to CD34(+) hematopoietic stem cells (HSCs) and was associated with sensitization rather than Treg induction. The recent discovery of a 'layered' T-cell development in humans whereby fetal HSCs are more likely to produce Tregs than adult HSCs, which may explain why MMc often induces tolerance, whereas FMc tends to induce sensitization.
Summary
Microchimerism may cause tolerance resulting in acceptance of an allograft bearing antigens shared by the microchimeric cells. However, microchimerism may also cause sensitization resulting in rejection. Distinguishing these effects prior to the transplant may revolutionize the field of living-related renal transplantation wherein MMc and FMc can exert a powerful influence on graft outcome.

AB Purpose of review
The present review updates the current status of research for induction of tolerance through a mixed chimerism approach in nonhuman primates and humans.
Recent findings
Allograft tolerance has been successfully achieved with a nonmyeloablative conditioning regimen and donor bone marrow transplantation in human leukocyte antigen (HLA)-matched and mismatched kidney transplantation. In HLA-matched kidney transplantation, persistent mixed chimerism and renal allograft tolerance has been achieved in some patients. In HLA-mismatched combinations, induction of persistent mixed chimerism has not been achieved using a nonmyeloablative preparative regimen. Nevertheless, the transient mixed chimerism that has been achieved has resulted in long-term renal allograft tolerance in the majority of patients. Recent preclinical studies have demonstrated that the presence of heterologous memory T-cell responses observed in primates, but not in rodents, may be a major barrier for induction of durable chimerism and tolerance in primates. Strategies to overcome such memory T-cell responses may, therefore, be of great value in the development of reliable protocols for clinical tolerance induction.
Summary
Induction of tolerance in clinical kidney transplantation has been achieved via mixed chimerism approaches. Improvements in the consistency and safety of tolerance induction and extension of successful protocols to other organs and to organs from deceased donors will all be among the next steps in bringing tolerance to a wider range of clinical applications.

AB The digestive tract epithelium and its adjoining mesenchyme undergo coordinated patterning and growth during development. The signals they exchange in the process are not fully characterized but include ligands of the Hedgehog (Hh) family, which originate in the epithelium and are necessary for mesenchymal cells to expand in number and drive elongation of the developing gut tube. The Notch signaling pathway has known requirements in fetal and adult intestinal epithelial progenitors. We detected Notch pathway activity in the embryonic gut mesenchyme and used conditional knockout mice to study its function. Selective disruption of the Notch effector gene RBP-J kappa (Rbpj) in the mesenchyme caused progressive loss of subepithelial fibroblasts and abbreviated gut length, revealing an unexpected requirement in this compartment. Surprisingly, constitutive Notch activity also induced rapid mesenchymal cell loss and impaired organogenesis, probably resulting from increased cell death and suggesting the need for a delicate balance in Notch signaling. Because digestive tract anomalies in mouse embryos with excess Notch activity phenocopy the absence of Hh signaling, we postulated that endodermal Hh restrains mesenchymal Notch pathway activity. Indeed, Hh-deficient embryos showed Notch overactivity in their defective gut mesenchyme and exposure to recombinant sonic hedgehog could override Notch-induced death of cultured fetal gut mesenchymal cells. These results reveal unexpected interactions between prominent signals in gastrointestinal development and provide a coherent explanation for Hh requirements in mesenchymal cell survival and organ growth.

AB We describe here a novel transgenic zebrafish, Tg(zpc:G4VP16/UAS:nfsB-mCherry) that effectively demonstrates the targeted oocyte ablation in the adult zebrafish ovary. This transgenic line expresses bacterial nitroreductase enzyme (nfsB) under the control of the oocyte-specific zona pellucida C (zpc) gene promoter. Adult transgenic females exposed to the prodrug metronidazole demonstrated near-complete ablation of growing oocytes, resulting in ovarian degeneration and complete cessation of reproductive function. Within 4 weeks of prodrug removal, treated fish demonstrated complete anatomical regeneration of the ovary and, within 7 weeks, ovarian function (fertility) was fully restored. Together, these results demonstrate functional renewal of the oocyte pool in the adult zebrafish ovary. Accordingly, this transgenic zebrafish model system provides a novel means to investigate ovarian growth dynamics in a genetically tractable vertebrate, and may be useful for evaluating signaling interactions that regulate gonadal development processes such as de novo oogenesis.

AB Kidney nephrons are composed of proximal and distal tubule segments that perform unique roles in excretion. The developmental pathways that establish nephron segment identities from renal progenitors are poorly understood. Here, we used the zebrafish pronephros to study nephron segmentation. We found that zebrafish nephron progenitors undergo elaborate spatiotemporal expression changes of many genes before adopting a segment fate. Initially, two domains of nephron progenitors are established, then are subdivided and demarcate individual nephron segments. Using genetic and chemical genetic models of retinoic acid (RA) deficiency, we discovered that RA modulates rostral progenitor formation. To delineate downstream pathways, we knocked down the irx3b transcription factor and found it regulates proximal tubule segment size and distal segment differentiation. Our results suggest a model whereby RA patterns the early field of nephron progenitors, with subsequent factors like irx3b acting to refine later progenitor subdomains and ensure activation of segment-specific gene programs.

AB The endogenous production of stromal cell-derived factor-1 (SDF-1) in beta cells in transgenic mice attenuates the development of diabetes in response to streptozotocin. Here we propose that beta cell injury induces SDF-1 production, and the SDF-1/chemokine (C-X-C motif) receptor 4 (CXCR4) interaction auto-activates Sdf1 expression, resulting in the autocrine production of SDF-1 by beta cells and the paracrine activation of glucagon-like peptide-1 (GLP-1) production by alpha cells.
SDF-1 production in adult mouse and human islets and rat INS-1 cells was measured in models of beta cell injury. The paracrine actions of SDF-1 on GLP-1 production in alpha cells were explored. The potential synergism between the growth-promoting actions of GLP-1 and the pro-survival actions of SDF-1 on the preservation of cell mass was evaluated by cell viability assays.
In adult islets and INS-1 cells, Sdf1 expression was re-induced in response to injury. The interaction of SDF-1 with its receptor on alphaTC1 cells activated protein kinase Akt, stimulated cell proliferation and induced the expression of prohormone convertase 1/3 and the consequent production of GLP-1 in alpha cells. The combination of GLP-1 and SDF-1 additively enhanced both the growth and longevity of INS-1 beta cells.
The results of these studies suggest that in response to beta cell injury and the ensuing induction of SDF-1, the biological function of alpha cells switches from the production of glucagon to the provision of the local growth factor GLP-1 which, in combination with SDF-1, promotes the growth, survival and viability of the beta cells.

AB Objective: Short-term energy deprivation reduces leptin concentrations and alters the levels of circulating hormones of the hypothalamic-pituitary-peripheral axis in lean subjects. Whether the reduction in leptin concentration during long-term weight loss in obese individuals is linked to the same neuroendocrine changes seen in lean, leptin-sensitive subjects remains to be fully clarified.
Methods: In this study, 24 overweight and obese adults (16 women and eight men; body mass index (BMI): 27.5-38.0 kg/m(2)) were prescribed a hypocaloric diet (-500 kcal/day) and were randomized to receive recombinant methionyl leptin (n = 18, metreleptin, 10 mg/day self-injected s.c.) or placebo (n = 6, same volume and time as metreleptin) for 6 months.
Results: Metreleptin administration did not affect weight loss beyond that induced by hypocaloric diet alone (P for interaction = 0.341) but increased the serum concentrations of total leptin by six-to eight-fold (P<0.001) and led to the generation of anti-leptin antibodies. Despite free leptin concentration (P for interaction = 0.041) increasing from 9 +/- 1 ng/ml at baseline to 43 +/- 15 and 36 +/- 12 ng/ml at 3 and 6 months, respectively, changes in circulating hormones of the thyroid and IGF axes at 3 and 6 months were not significantly different in the placebo-and metreleptin-treated groups.
Conclusions: Leptin does not likely mediate changes in neuroendocrine function in response to weight loss induced by a mild hypocaloric diet in overweight and obese subjects.

AB Background Diagnostic and therapeutic procedures of gastroenterology can frequently tax a patient's health. In addition to the risk of side-effects such procedures may also reduce the patient's well-being. The probability of achieving cure depends on the interplay between the patient's initial health status and the expected efficacy of the gastroenterological interventions.
Methods The mathematical concept of the 'gambler's ruin' from probability theory is used to model the interplay among the various factors affecting clinical outcome.
Results The model illustrates in a quantitative manner how the physician's ultimate success in achieving cure depends on a given patient's initial health status, and the characteristics of the interventional procedures used. The analysis also illustrates that in some dire clinical situations, risking the patient's life in one single and bold step can yield a better overall outcome than trying to advance the patient's health by multiple small and cautious steps.
Conclusion Using the gambler's ruin as a model for medical risk taking could contribute to medical teaching and promote the understanding of the some general principles that shape many clinical decisions in gastroenterology.

AB Fluoxetine, one of the selective serotonin reuptake inhibitors (SSRIs), has been found to possess immune modulation effects, in addition to its antidepressant effects. However, it remains unclear whether SSRIs can suppress the antigen-presenting function of dendritic cells (DCs). Therefore, Fluoxetine was applied to a co-culture of Aggregatibacter actinomycetemcomitans (Aa)-reactive T cells (x Aa-T) isolated from Aa-immunized mice and DCs. This resulted in the suppressed proliferation of x Aa-T stimulated with Aa-antigen presentation by DCs. Specifically, Fluoxetine increased the extracellular 5-hydroxytryptamine (5-HT) in the x Aa-T/DC co-culture, whereas exogenously applied 5-HT promoted T-cell proliferation in the x Aa-T/DC co-culture, indicating that Fluoxetine-mediated suppression of x Aa-T/DC responses cannot be attributed to extracellular 5-HT. Instead, Fluoxetine remarkably suppressed the expression of costimulatory molecule ICOS-L on DCs. Fluoxetine also promoted a greater proportion of CD86(Low) immature DCs than CD86(High) mature DCs, while maintaining the expression levels of CD80, MHC-class-II and PD-L1. These results suggested that Fluoxetine suppressed the ability of DCs to present bacterial antigens to T cells, and the resulting T-cell proliferation, in a SERT/5-HT-independent manner and that diminished expression of ICOS-L on DCs and increase of CD86(Low) immature DCs caused by Fluoxetine might be partially associated with Fluoxetine-mediated suppression of DC/T-cell responses.

AB X-chromosome inactivation is an epigenetic hallmark of mammalian development. Chromosome-wide regulation of the X-chromosome is essential in embryonic and germ cell development. In the male germline, the X-chromosome goes through meiotic sex chromosome inactivation, and the chromosome-wide silencing is maintained from meiosis into spermatids before the transmission to female embryos. In early female mouse embryos, X-inactivation is imprinted to occur on the paternal X-chromosome, representing the epigenetic programs acquired in both parental germlines. Recent advances revealed that the inactive X-chromosome in both females and males can be dissected into two elements: repeat elements versus unique coding genes. The inactive paternal X in female preimplantation embryos is reactivated in the inner cell mass of blastocysts in order to subsequently allow the random form of X-inactivation in the female embryo, by which both Xs have an equal chance of being inactivated. X-chromosome reactivation is regulated by pluripotency factors and also occurs in early female germ cells and in pluripotent stem cells, where X-reactivation is a stringent marker of naive ground state pluripotency. Here we summarize recent progress in the study of X-inactivation and X-reactivation during mammalian reproduction and development as well as in pluripotent stem cells.

AB Randomized placebo-controlled trials (RCTs) are standard for assessing efficacy and safety of treatments. We pursued preliminary indications that some factors are associated differentially with responses to placebo or drugs in RCTs for bipolar mania. We meta-analysed data from RCTs to assess influences of study-site count, subjects' age, sex distribution, diagnostic subgroups, clinical features, trial-completion rates, and publication year on mean difference (MD) in mania ratings between intake and final assessments. In 38 RCTs involving 3812 placebo-treated and 6988 drug-treated patients, symptomatic improvement was similar in placebo arms of trials of effective (6.77, 95% CI 5.77-7.76) and ineffective (7.61, 95% CI 5.47-8.75) drugs. Lesser placebo responses (MD) and greater drug-placebo differences (Hedges' g) were associated with fewer study sites, younger patients' age, and male sex. More patients with initial psychotic features and more trial completion in drug arms were associated with greater drug-associated improvement (MD) and drug-placebo contrast (Hedges' g), whereas more mixed-state diagnoses decreased both measures. Identifying modifying factors can support more efficient and cost-effective designs of therapeutic trials. In trials for mania, fewer sites may limit placebo response and enhance drug-placebo contrasts.

AB Treatment for negative symptoms and cognitive deficits, core elements of schizophrenia, remains inadequate. Stimulation of the prefrontal cortex via transcranial magnetic stimulation (TMS) yields only moderate results, possibly due to limited stimulation depth. Deep-TMS enables deeper and wider stimulation than before. This preliminary study is the first to examine deep-TMS as a possible add-on treatment for negative symptoms and cognitive deficits of schizophrenia. The effect of 20 daily deep-TMS sessions (20 Hz, 120% motor threshold) over the prefrontal cortex of 15 patients indicated improvement in cognition and negative symptoms that was maintained at 2-wk post-treatment follow-up.

AB Polymorphisms in the SLAM family of leukocyte cell surface regulatory molecules have been associated with lupus-like phenotypes in both humans and mice. The murine Slamf gene cluster lies within the lupus-associated Sle1b region of mouse chromosome 1. Non-autoreactive C57BL/6 (B6) mice that have had this region replaced by syntenic segments from other mouse strains (i.e. 129, NZB and NZW) are B6 congenic strains that spontaneously produce non-nephritogenic lupus-like autoantibodies. We have recently reported that genetic ablation of the SLAM family member CD48 (Slam) drives full-blown autoimmune disease with severe proliferative glomerulonephritis (CD48GN) in B6 mice carrying 129 sequences of the Sle1b region (B6.129CD48(-/-)). We also discovered that BALB/c mice with the same 129-derived CD48-null allele (BALB.129CD484(-/-)) have neither nephritis nor anti-DNA autoantibodies, indicating that strain specific background genes modulate the effects of CD48 deficiency. Here we further examine this novel model of lupus nephritis in which CD48 deficiency transforms benign autoreactivity into fatal nephritis. CD48GN is characterized by glomerular hypertrophy with mesangial expansion, proliferation and leukocytic infiltration. Immune complexes deposit in mesangium and in subendothelial, sub-epithelial and intramembranous sites along the glomerular basement membrane. Afflicted mice have low-grade proteinuria, intermittent hematuria and their progressive renal injury manifests with elevated urine NGAL levels and with uremia. In contrast to the lupus-like B6.129CD48(-/-) animals, neither BALB.129CD48(-/-) mice nor B6 x BALB/c F1.129CD48(-/-) progeny have autoimmune traits, indicating that B6-specific background genes modulate the effect of CD48 on lupus nephritis in a recessive manner.

AB Pathology in the heart can be examined at several scales, ranging from the molecular to the macroscopic. Traditionally, fluorescence-based techniques such as flow cytometry have been used to study the myocardium at the molecular, cellular, and microscopic levels. Recent advances in magnetic resonance imaging (MRI), however, have made it possible to image certain cellular and molecular events in the myocardium noninvasively in vivo. In addition, diffusion MRI has been used to image myocardial fiber architecture and microstructure in the intact heart. Diffusion MRI tractography, in particular, is providing novel insights into myocardial microsctructure in both health and disease. Recent developments have also been made in fluorescence imaging, making it possible to image fluorescent probes in the heart of small animals noninvasively in vivo. Moreover, techniques have been developed to perform in vivo fluorescence tomography of the mouse heart. These advances in MRI and fluorescence imaging allow events in the myocardium to be imaged at several scales linking molecular changes to alterations in microstructure and microstructural changes to gross function. A complete and integrated picture of pathophysiology in the myocardium is thus obtained. This multiscale approach has the potential to be of significant value not only in preclinical research but, ultimately, in the clinical arena as well.

RECEPTOR GENE; HORMONE; IDENTIFICATION
AB Sporadic primary hyperparathyroidism (PHPT), one of the most common endocrine disorders, is characterized by hypercalcemia and elevated PTH levels. The majority of cases are caused by a benign parathyroid adenoma, but somatic or de novo germ-line mutations that lead to adenoma formation have only been identified in few glands. GCMB is a parathyroid-specific transcription factor, which causes hypoparathyroidism when inactivated on both parental alleles or when a dominant-negative, heterozygous mutation is present. It is overexpressed in some parathyroid adenomas, and we therefore tested the hypothesis that GCMB mutations can be a cause of parathyroid adenomas. Nucleotide sequence analysis was performed on all coding exons and exon-intron borders of GCMB in 30 sporadic parathyroid adenomas and we identified several known polymorphisms that were either heterozygous or homozygous. In addition, one of the 30 investigated glands revealed a novel heterozygous missense mutation, c. 1144G>A, which introduced methionine at position 382 for valine (V382M), a conserved amino acid residue. Western blot analysis using mutant GCMB (GCMB-V382M) from lysates of transiently transfected DF-1 fibroblasts, luciferase assays using extracts from these cells, and electrophoretic mobility assays failed to reveal differences between wild-type and mutant GCMB in expression level, transactivational capacity, and DNA-binding ability. Furthermore, pulse-chase experiments demonstrated no difference in half-life of wild-type and mutant protein. We conclude that mutations in the transcription factor GCMB do not seem to play a major role in the pathogenesis of PHPT. Journal of Endocrinology (2011) 210, 165-171

AB Optimal cognitive functioning is necessary to successfully negotiate one's environment, yet medical conditions can interfere with brain health, thus negatively impacting cognitive functioning. Such comorbidities include hypertension, heart disease, diabetes, depression, and HIV, as well as others. The physiological properties of these comorbidities can reduce one's cognitive reserve and limit one's cognitive efficiency. This article provides an overview of a few common comorbidities known to affect cognitive functioning and addresses ways in which cognitive functioning may be ameliorated and protected or mitigated in lieu of cognitive declines in such clinical populations. Implications for nursing practice and research are posited.

AB Production of tissue engineered small intestine (TESI) has been limited by the relatively large amount of native tissue required to generate neomucosa. The influence of growth factors and three-dimensional (3D) extracellular matrices on TESI has been studied both in vitro and in vivo, and positive growth effects on tissue mass and differentiation were noted. The present study investigates the impact of single doses of glucagon-like peptide-2 (GLP-2), hepatocyte growth factor (HGF), or holo-transferrin adsorbed onto a polyglycolic (PGA) mesh scaffold using a rat small-intestinal organoid transplant model. In Experiment I, intestinal organoids were seeded onto PGA mesh discs, suspended in either Matrigel (n = 8) or a vehicle control (n = 8), and implanted into syngenic recipients. In Experiment II, GLP-2 (n = 8), HGF (n = 8), or transferrin (n = 8) were adsorbed onto PGA mesh discs. Intestinal organoids were then suspended in Matrigel and seeded onto each growth factor-loaded PGA disc or onto control discs without growth factors (n = 12). In addition, organoids were suspended in vehicle and seeded onto control discs (n = 12). All discs were implanted into syngenic recipients. After 4 wk, histologic analysis of the samples revealed significantly greater neomucosal surface area (3.62 +/- 0.33 mm(2) versus 0.92 +/- 0.11 mm(2), P < 0.0001) and cyst diameter (2.83 +/- 0.14 mm versus 2.06 +/- 0.07 mm, P < 0.0001) in groups treated with Matrigel compared with vehicle controls. The addition of holo-transferrin to the scaffolds further augmented neomucosal surface area (9.11 +/- 0.66 mm(2) versus 3.01 +/- 0.22 mm(2), P < 0.01), whereas that of GLP-2 stimulated the formation of increased numbers of cysts (8.88 +/- 0.46 versus 4.18 +/- 0.25, P < 0.01). These data suggest that Matrigel and growth factors adsorbed to polymer scaffolds can be used to manipulate the morphology of TESI. Published by Elsevier Inc.

AB Background Psoriasis is an inflammatory disease that not only affects the skin but can also have systemic implications such as obesity and nutritional deficiencies. Carotenoids are vitamin A provitamins with anti-oxidant properties that are present in human tissues including skin.
Objectives To determine whether psoriasis is associated with lower levels of skin carotenoid levels.
Methods In this cross-sectional study, skin carotenoid levels were measured on the palms of 44 patients with psoriasis and 72 patients without psoriasis. A linear regression model was used to evaluate the relationship between psoriasis and carotenoid levels (primary aim) and to determine if severity of disease was associated with carotenoid levels (secondary aim). Potential confounders included demographic factors, smoking status, body mass index and multivitamin intake.
Results The mean carotenoid levels in the psoriasis and no psoriasis groups were respectively 22 099 and 29 180 and presence of psoriasis was found to be significantly related to lower levels of carotenoids in both univariable and multivariable analysis (P < 0.05). In the psoriasis group, the Psoriasis Area and Severity Index score was not significantly related to carotenoid levels (P = 0.07).
Conclusions Patients with psoriasis appear to have lower skin carotenoid counts than patients without psoriasis.

AB Mantle cell lymphoma (MCL) is a non-Hodgkin lymphoma that is incurable with standard chemotherapy. There is no consensus on the best initial therapy, especially for elderly patients, who are not candidates for aggressive treatment approaches. Current National Comprehensive Cancer Network (NCCN) treatment guidelines include rituximab (R) plus cladribine for the initial treatment of MCL. However, few data are available to substantiate this recommendation. Therefore, to further define the role of R-cladribine for the initial treatment of MCL, we performed a retrospective chart review of 31 patients with MCL (median age, 67) treated with R-cladribine. The majority of responding patients also received R maintenance. The overall response rate was 87%, with 61% of patients achieving a complete remission (CR/CRu). The estimated median follow-up was 32.5 months, median PFS was 37.5 months, and median OS was 85.2 months. One of 19 (5.3%) subjects in CR/CRu relapsed (median follow-up of 23 months). CR/CRu was associated with improved survival (p < 0.0001), while a high mantle cell international prognostic index (MIPI) was associated with worse survival (p = 0.05). There was one toxic death (neutropenic pseudomonal sepsis) related to treatment. R-cladribine is an effective therapy for previously untreated MCL, and these results validate the use of R-cladribine for the initial treatment of MCL.

AB Over the past decade, histone deacetylase inhibitors have increasingly been used to treat various malignancies. Tubacin (tubulin acetylation inducer) is a small molecule that inhibits histone deacetylase 6 (HDAC6) and induces acetylation of alpha-tubulin. We observed a higher antiproliferative effect of tubacin in acute lymphoblastic leukemia (ALL) cells than in normal hematopoietic cells. Treatment with tubacin led to the induction of apoptotic pathways in both pre-B and T cell ALL cells at a 50% inhibitory concentration (IC(50)) of low micromolar concentrations. Acetylation of alpha-tubulin increases within the first 30 min following treatment of ALL cells with tubacin. We also observed an accumulation of polyubiquitinated proteins and poly(ADP-ribose) polymerase (PARP) cleavage. Furthermore, the signaling pathways activated by tubacin appear to be distinct from those observed in multiple myeloma. In this article, we demonstrate that tubacin enhances the effects of chemotherapy to treat primary ALL cells in vitro and in vivo. These results suggest that targeting HDAC6 alone or in combination with chemotherapy could provide a novel approach to treat ALL.

AB Objective: Studies suggest that a business case for improving nurse staffing can be made to increase registered nurse (RN) skill mix without changing total licensed nursing hours. It is unclear whether a business case for increasing RN skill mix can be justified equally among patients of varying health needs. This study evaluated whether nursing hours per patient day (HPPD) and skill mix are associated with higher inpatient care costs within acute medical/surgical inpatient units using data from the Veterans Health Administration.
Methods: Retrospective cross-sectional study, including 139,360 inpatient admissions to 292 acute medical/surgical units at 125 Veterans Health Administration medical centers between February and June 2003, was conducted. Dependent variables were inpatient costs per admission and costs per patient day.
Results: The average costs per surgical and medical admission were $18,624 and $6,636, respectively. Costs per admission were positively associated with total nursing HPPD among medical admissions ($164.49 per additional HPPD, P < 0.001), but not among surgical admissions. Total nursing HPPD and RN skill mix were associated with higher costs per hospital day for both medical admissions ($79.02 per additional HPPD and $5.64 per 1% point increase in nursing skill mix, both P < 0.001) and surgical admissions ($112.47 per additional HPPD and $13.31 per 1% point increase in nursing skill mix, both P < 0.001). Patients experiencing complications or transferring to an intensive care unit had higher inpatient costs than other patients.
Conclusions: The association of nurse staffing level with costs per admission differed for medical versus surgical admissions.

Association between Physical Activity and Kidney Function: National Health and Nutrition Examination Survey. Med. Sci. Sports Exerc., Vol. 43, No. 8, pp. 1457-1464, 2011. Introduction: Chronic kidney disease is a condition characterized by the deterioration of the kidney's ability to remove waste products from the body. Although treatments to slow the progression of the disease are available, chronic kidney disease may eventually lead to a complete loss of kidney function. Previous studies have shown that physical activities of moderate intensity may have renal benefits. Few studies have examined the effects of total movement on kidney function. The purpose of this study was to determine the association between time spent at all levels of physical activity intensity and sedentary behavior and kidney function. Methods: Data were obtained from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Survey, a cross-sectional study of a complex, multistage probability sample of the US population. Physical activity was assessed using an accelerometer and questionnaire. Glomerular filtration rate (eGFR) was estimated using the Modification of Diet in Renal Disease study formula. To assess linear associations between levels of physical activity and sedentary behavior with log-transformed estimated GFR (eGFR), linear regression was used. Results: In general, physical activity (light and total) was related to log eGFR in females and males. For females, the association between light and total physical activity with log eGFR was consistent regardless of diabetes status. For males, the association between light and total physical activity and log eGFR was only significant in males without diabetes. Conclusions: When examining the association between physical activity, measured objectively with an accelerometer, and kidney function, total and light physical activities were found to be positively associated with kidney function.

AB Inositol phosphates are widely produced throughout animal and plant tissues. Diphosphoinositol pentakisphosphate (InsP7) contains an energetic pyrophosphate bond. Here we demonstrate that disruption of inositol hexakisphosphate kinase 1 (InsP6K1), one of the three mammalian inositol hexakisphosphate kinases (InsP6Ks) that convert inositol hexakisphosphate (InsP6) to InsP7, conferred enhanced phosphatidylinositol-(3,4,5)-trisphosphate (PtdIns(3,4,5)P(3))-mediated membrane translocation of the pleckstrin homology domain of the kinase Akt and thus augmented downstream PtdIns(3,4,5)P(3) signaling in mouse neutrophils. Consequently, these neutrophils had greater phagocytic and bactericidal ability and amplified NADPH oxidase-mediated production of superoxide. These phenotypes were replicated in human primary neutrophils with pharmacologically inhibited InsP6Ks. In contrast, an increase in intracellular InsP7 blocked chemoattractant-elicited translocation of the pleckstrin homology domain to the membrane and substantially suppressed PtdIns(3,4,5)P(3)-mediated cellular events in neutrophils. Our findings establish a role for InsP7 in signal transduction and provide a mechanism for modulating PtdIns(3,4,5)P(3) signaling in neutrophils.

AB How the pore-forming protein perforin delivers apoptosis-inducing granzymes to the cytosol of target cells is uncertain. Perforin induces a transient Ca(2+) flux in the target cell, which triggers a process to repair the damaged cell membrane. As a consequence, both perforin and granzymes are endocytosed into enlarged endosomes called 'gigantosomes'. Here we show that perforin formed pores in the gigantosome membrane, allowing endosomal cargo, including granzymes, to be gradually released. After about 15 min, gigantosomes ruptured, releasing their remaining content. Thus, perforin delivers granzymes by a two-step process that involves first transient pores in the cell membrane that trigger the endocytosis of granzyme and perforin and then pore formation in endosomes to trigger cytosolic release.

AB Here we have used a systems biology approach to study innate and adaptive responses to vaccination against influenza in humans during three consecutive influenza seasons. We studied healthy adults vaccinated with trivalent inactivated influenza vaccine (TIV) or live attenuated influenza vaccine (LAIV). TIV induced higher antibody titers and more plasmablasts than LAIV did. In subjects vaccinated with TIV, early molecular signatures correlated with and could be used to accurately predict later antibody titers in two independent trials. Notably, expression of the kinase CaMKIV at day 3 was inversely correlated with later antibody titers. Vaccination of CaMKIV-deficient mice with TIV induced enhanced antigen-specific antibody titers, which demonstrated an unappreciated role for CaMKIV in the regulation of antibody responses. Thus, systems approaches can be used to predict immunogenicity and provide new mechanistic insights about vaccines.

AB Transcranial direct current stimulation (tDCS) has recently emerged as a promising approach to enhance neurorehabilitative outcomes. However, little is known about how the local electrical field generated by tDCS relates to underlying neuroplastic changes and behavior. To address this question, we present a case study analysis of an individual with hemianopia due to stroke and who benefited from a combined visual rehabilitation training and tDCS treatment program. Activation associated with a visual motion perception task (obtained by functional magnetic resonance imaging; fMRI) was used to characterize local changes in brain activity at baseline and after training. Individualized, high-resolution electrical field modeling reproducing precise cerebral and lesioned tissue geometry, predicted distortions of current flow in peri-lesional areas and diffuse clusters of peak electric fields. Using changes in fMRI signal as an index of cortical recovery, correlations to the electrical field map were determined. Significant correlations between the electrical field and change in fMRI signal were region specific including cortical areas under the anode electrode and peri-lesional visual areas. These patterns were consistent with effective tDCS facilitated rehabilitation. We describe the methodology used to analyze tDCS mechanisms through combined fMRI and computational modeling with the ultimate goal of developing a rationale for individualized therapy.

AB Time of arrival (TOA) of a bolus of contrast agent to the tissue voxel is a reference time point critical for the Early Time Points Perfusion Imaging Method (ET) to make relative cerebral blood flow (rCBF) maps. Due to the low contrast to noise (CNR) condition at TOA, other useful reference time points known as relative time of arrival data points (rTOA) are investigated. Candidate rTOA's include the time to reach the maximum derivative, the maximum second derivative, and the maximum fractional derivative. Each rTOA retains the same relative time distance from TOA for all tissue flow levels provided that ET's basic assumption is met, namely, no contrast agent has a chance to leave the tissue before the time of rTOA. The ET's framework insures that rCBF estimates by different orders of the derivative are theoretically equivalent to each other and monkey perfusion imaging results supported the theory. In rCBF estimation, maximum values of higher order fractional derivatives may be used to replace the maximum derivative which runs a higher risk of violating ET's assumption. Using the maximum values of the derivative of orders ranging from 1 to 1.5 to 2. estimated rCBF results were found to demonstrate a gray white matter ratio of approximately 3, a number consistent with flow ratio reported in the literature.

AB One goal of in vivo neuroimaging is the detection of neurodegenerative processes and anatomical reorganizations after spinal cord (SC) injury. Non-invasive examination of white matter fibers in the living SC can be conducted using magnetic resonance diffusion-weighted imaging. However, this technique is challenging at the spinal level due to the small cross-sectional size of the cord and the presence of physiological motion and susceptibility artifacts. In this study, we acquired in vivo high angular resolution diffusion imaging (HARDI) data at 3T in cats submitted to partial SC injury. Cats were imaged before. 3 and 21 days after injury. Spatial resolution was enhanced to 1.5 x 1.5 x 1 mm(3) using super-resolution technique and distortions were corrected using the reversed gradient method. Tractography-derived regions of interest were generated in the dorsal, ventral, right and left quadrants. to evaluate diffusion tensor imaging (DTI) and Q-Ball imaging metrics with regards to their sensitivity in detecting primary and secondary lesions. A three-way ANOVA tested the effect of session (intact, D3, D21), cross-sectional region (left, right, dorsal and ventral) and rostrocaudal location. Significant effect of session was found for FA (P<0.001), GFA (P<0.05) and radial diffusivity (P<0.001). Post-hoc paired T-test corrected for multiple comparisons showed significant changes at the lesion epicenter (P<0.005). More interestingly, significant changes were also found several centimeters from the lesion epicenter at both 3 and 21 days. This decrease was specific to the type of fibers, i.e.. rostrally to the lesion on the dorsal aspect of the cord and caudally to the lesion ipsilaterally, suggesting the detection of Wallerian degeneration.

AB Varicella zoster virus (VZV) is a neurotropic herpesvirus that infects nearly all humans. Primary infection usually causes chickenpox (varicella), after which virus becomes latent in cranial nerve ganglia, dorsal root ganglia and autonomic ganglia along the entire neuraxis. Although VZV cannot be isolated from human ganglia, nucleic acid hybridization and, later, polymerase chain reaction proved that VZV is latent in ganglia. Declining VZV-specific host immunity decades after primary infection allows virus to reactivate spontaneously, resulting in shingles (zoster) characterized by pain and rash restricted to one to three dermatomes. Multiple other serious neurological and ocular disorders also result from VZV reactivation. This review summarizes the current state of knowledge of the clinical and pathological complications of neurological and ocular disease produced by VZV reactivation, molecular aspects of VZV latency, VZV virology and VZV-specific immunity, the role of apoptosis in VZV-induced cell death and the development of an animal model provided by simian varicella virus infection of monkeys.

AB In anxiety disorders, such as posttraumatic stress disorders and phobias, classical conditioning pairs natural (unconditioned) fear-eliciting stimuli with contextual or discrete cues resulting in enduring fear responses to multiple stimuli. Extinction is an active learning process that results in a reduction of conditioned fear responses after conditioned stimuli are no longer paired with unconditioned stimuli. Fear extinction often produces incomplete effects and this highlights the relative permanence of bonds between conditioned stimuli and conditioned fear responses. The animal research literature is rich in its demonstration of cognitive enhancing agents that alter fear extinction. This review specifically examines the fear extinguishing effects of cognitive enhancers that act on gamma-aminobutyric acid (GABA), glutamatergic, cholinergic, adrenergic, dopaminergic, and cannabinoid signaling pathways. It also examines the effects of compounds that alter epigenetic and neurotrophic mechanisms in fear extinction. Of these cognitive enhancers, glutamatergic N-methyl D-aspartate (NMDA) receptor agonists, such as D-cycloserine, have enhanced fear extinction in a context-, dose- and time-dependent manner. Agents that function as glutamatergic alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor agonists, alpha2-adrenergic receptor antagonists (such as yohimbine), neurotrophic factors (brain derived neurotrophic factor or BDNF) and histone deacetylase inhibitors (valproate and sodium butyrate) also improve fear extinction in animals. However, some have anxiogenic effects and their contextual and temporal effects need to be more reliably demonstrated. Various cognitive enhancers produce changes in cortico-amygdala synaptic plasticity through multiple mechanisms and these neural changes enhance fear extinction. We need to better define the changes in neural plasticity produced by these agents in order to develop more effective compounds. In the clinical setting, such use of effective cognitive enhancers with cue exposure therapy, using compounds derived from animal model studies, provides great hope for the future treatment of anxiety disorders.

AB Cognitive deficits are major contributors to disability in schizophrenia. Many pharmacologic targets have been identified for cognitive enhancing agents, including receptors involved in dopaminergic, glutamatergic, GABAergic, serotonergic and cholinergic neurotransmission. In addition, new approaches to drug development have been directed towards neuroprotection and the facilitation of neuroplasticity. While several pharmacologic agents and cognitive remediation have shown promise in early trials, no treatment has yet demonstrated efficacy in large replication trials. The experience with different pharmacologic targets is reviewed and methodologic issues are discussed with recommendations for future research. (C) 2010 Elsevier Inc. All rights reserved.

AB Attenuation of drug reward has been the major focus of medication development in the addiction area to date. With the growth of research in the area of cognitive neuroscience, the importance of executive function and inhibitory cognitive control in addictive disorders is becoming increasingly apparent. An emerging strategy in the pharmacotherapy of addictions and other psychiatric disorders involves the use of medications that improve cognitive function.
In particular, agents that facilitate inhibitory and attentional control, improve abstraction, planning and mental flexibility could be beneficial in the treatment of substance use disorders. Because there are multiple neurotransmitter systems involved in the regulation of cognitive function, agents from a number of drug classes have been tested. In particular, agents acting through the cholinergic, adrenergic and glutamatergic systems have shown potential for improving cognitive function in a number of psychiatric and neurologic disorders, but most of these agents have not been tested in the treatment of individuals with substance use disorders. This manuscript provides a review of clinical data supporting the use of the major classes of cognitive enhancing agents in substance use disorders. Agents that have shown promise in cognitive enhancement in other disorders, and have a theoretical or mechanistic rationale for application to substance use disorders are also highlighted.

AB Background. Some personality characteristics have previously been associated with an increased risk for psychiatric disorder. Longitudinal studies are required in order to tease apart temporary (state) and enduring (trait) differences in personality among individuals with bipolar disorder (BD). This study aimed to determine whether there is a characteristic personality profile in BD, and whether associations between BD and personality are best explained by state or trait effects.
Method. A total of 2247 participants in the Systematic Treatment Enhancement Program for Bipolar Disorder study completed the NEO Five-Factor Inventory administered at study entry, and at 1 and 2 years.
Results. Personality in BD was characterized by high neuroticism (N) and openness (O), and low agreeableness (A), conscientiousness (C) and extraversion (E). This profile was replicated in two independent samples, and openness was found to distinguish BD from major depressive disorder. Latent growth modeling demonstrated that manic symptoms were associated with increased E and decreased A, and depressed symptoms with higher N and lower E, A, C and O. During euthymic phases, high N and low E scores predicted a future depression-prone course.
Conclusions. While there are clear state effects of mood on self-reported personality, personality variables during euthymia predict future course of illness. Personality disturbances in extraversion, neuroticism and openness may be enduring characteristics of patients with BD.

AB Background
Stress perception and GI-specific anxiety play key roles in irritable bowel syndrome (IBS). Mindfulness-based stress reduction (MBSR) is a widely available stress reduction course, which has not been evaluated for IBS.
Aim
To determine whether participation in MBSR is associated with improvement in bowel symptoms, GI-specific anxiety, and IBS-Quality of Life.
Methods
This is a prospective study of 93 participants in MBSR. We applied measures of Rome III IBS status, bowel symptoms (IBS-Severity Scoring System, IBS-SSS), IBS-Quality of Life (IBS-QOL), GI-specific anxiety (Visceral Sensitivity Index, VSI), mindfulness (Five Facet Mindfulness Questionnaire-FFMQ), and functional status (SF-8) at baseline and 2 and 6 months after enrolment.
Results
At 2 months, participation in MBSR was associated with small nonsignificant changes in IBS-SSS, IBS-QOL and VSI: d = -0.25, d = 0.08, d = -0.16, respectively. At 6 months, there was no significant change in IBS-SSS (d = -0.36); whereas for IBS-QOL and VSI there were significant improvements (IBS-QOL: d = 0.33, P = 0.044; VSI: d = -0.40, P = 0.014). For patients meeting Rome III IBS criteria (n = 43), changes in IBS-SSS, IBS-QOL and VSI were not statistically significant, but there was a significant correlation between the change in VSI and the change in FFMQ across the three time periods (r = 0.33).
Conclusions
Participation in MBSR is associated with improvement IBS-related quality of life and GI-specific anxiety. Randomised controlled trials are warranted to further assess the role of MBSR for IBS symptomatology.

AB Chorea is a common movement disorder that can be caused by a large variety of structural, neurochemical (including pharmacologic), or metabolic disturbances to basal ganglia function, indicating the vulnerability of this brain region. The diagnosis is rarely indicated by the simple phenotypic appearance of chorea, and can be challenging, with many patients remaining undiagnosed. Clues to diagnosis may be found in the patient's family or medical history, on neurologic examination, or upon laboratory testing and neuroimaging. Increasingly, advances in genetic medicine are identifying new disorders and expanding the phenotype of recognized conditions. Although most therapies at present are supportive, correct diagnosis is essential for appropriate genetic counseling, and ultimately, for future molecular therapies.

HEART-FAILURE; II RECEPTOR
AB The WHO classification of pulmonary hypertension (PH) recognises five distinct groups, all sharing a mean, resting, pulmonary artery pressure (PAP) > 25 mmHg. The aetiology of PH varies by group (1-pulmonary vascular disease, 2-high left heart filling pressures, 3-hypoxia, 4-unresolved pulmonary embolism and 5-miscellaneous). Inclusion in a group reflects shared histological, haemodynamic and pathophysiological features and has therapeutic implications. Advantages of using rodent models to understand the pathophysiology of human PH and to test experimental therapies include the economy, safety and mechanistic certainty they provide. As rodent models are meant to reflect human PH, they should be categorised by a parallel PH classification and limitations in achieving this ideal recognised. Challenges with rodent models include: accurate phenotypic characterisation (haemodynamics, histology and imaging), species and strain variations in the natural history of PH, and poor fidelity to the relevant human PH group. Rat models of group 1 PH include: monocrotaline (+/- pneumonectomy), chronic hypoxia + SU-5416 (a VEGF receptor inhibitor) and the fawn-hooded rat (FHR). Mouse models of group 1 PH include: transgenic mice overexpressing the serotonin transporter or dominant-negative mutants of bone morphogenetic protein receptor-2. Group 1 PH is also created by infecting S100A4/Mts1 mice with gamma-herpesvirus. The histological features of group 1 PH, but not PH itself, are induced by exposure to Schistosoma mansoni or Stachybotrys chartarum. Group 3 PH is modelled by exposure of rats or mice to chronic hypoxia. Rodent models of groups 2, 4 and 5 PH are needed. Comprehensive haemodynamic, histological and molecular phenotyping, coupled with categorisation into WHO PH groups, enhances the utility of rodent models.

AB Objective: To examine whether consistent low-risk drinking is associated with lower risk of developing functional limitations among older adults. Method: Data were obtained from five waves of the Health and Retirement Study. Function was assessed by questions measuring four physical abilities and five instrumental activities of daily living. Five different drinking patterns were determined using data over two consecutive survey periods. Results: Over the follow-up periods, 38.6% of older adults developed functional limitations. Consistent low-risk drinkers had lower odds of developing functional limitations compared with consistent abstainers, and the effect of consistent low-risk drinking was greater among those aged 50 to 64 years compared with those aged >= 65 years. Other drinking patterns were not associated with lower odds of incident functional limitation. Discussion: Consistent low-risk drinking was associated with lower odds of developing functional limitations, and this association was greater among older middle-aged adults aged 50 to 64 years.

AB Objectives: This study reports findings on functional change trajectories for long-stay residents by examining the effects of baseline medical conditions and functional status on changes in physical impairment across residents' length of stay (LOS). Method: A 5% sample of nursing home residents from Michigan from 1999 through 2003 was used to create longitudinal episodes of care including Minimum Data Set (MDS) assessments. Data were analyzed using hierarchical linear models. Results: On average, physical impairment increases throughout a resident's stay and is more rapid later in the stay. Greater physical and cognitive impairment at baseline leads to increasing impairment for residents whereas presence of baseline medical conditions, including heart disease and hip fracture, leads to slower rates of impairment. Discussion: Baseline functional status is critical to predicting changes in impairment while the impact of medical diagnoses is significant but weaker than the effect of baseline impairment.

AB Purpose: Androgen deprivation therapy for prostate cancer causes accelerated loss of bone mineral density and is associated with increased fracture risk. We evaluated risk factors associated with vertebral fractures among men enrolled in a fracture prevention trial.
Materials and Methods: Analysis included men receiving androgen deprivation therapy for prostate cancer and enrolled in a phase III fracture prevention trial. All men were 70 years old or older or had a low bone mineral density (T-score less than -1.5 for the lumbar spine or total hip). We analyzed demographic and laboratory characteristics of men with and those without vertebral fractures at study entry.
Results: Of the 1,244 subjects 162 (13.0%) had a vertebral fracture at baseline. The 2 factors significantly associated with vertebral fractures were white race (p = 0.028 compared with nonwhite race) and osteoporosis (p = 0.002 for osteoporosis at any site, p = 0.053 for osteoporosis at the spine, p = 0.002 for osteoporosis at the hip). Lower bone mineral density was also significantly associated with vertebral fractures when analyzed as a continuous variable. Factors not associated with vertebral fractures included age, country of residence, androgen deprivation therapy duration at baseline, androgen deprivation therapy mode, body mass index, testosterone, estradiol, C-telopeptide, bone specific alkaline phosphatase and osteocalcin. Results were similar in analyses limited to men 70 years old or older.
Conclusions: White race and low bone mineral density were significantly associated with vertebral fractures in this study of men treated with androgen deprivation for prostate cancer. These observations should inform the assessment and management of fracture risk among such men.

AB Purpose: The American Urological Association In-Service Examination and the American Board of Urology Qualifying Examination are written multiple choice tests that cover all domains in urology. We investigated whether In-Service Examination performance could identify chief residents who scored in the lowest quartile on the Qualifying Examination.
Materials and Methods: All urology chief residents in the United States and Canada in 2008 and 2009 were eligible to participate in this study. In-Service Examination 2008 and Qualifying Examination 2009 performance data were obtained from the American Urological Association and American Board of Urology, respectively. Data were analyzed with the Pearson correlation and descriptive statistics.
Results: Of the 257 American and Canadian chief residents who completed the Qualifying Examination 2009, 194 (75%) enrolled in this study and were included in analysis. Overall In-Service Examination 2008 scores correlated significantly with Qualifying Examination 2009 scores (r = 0.55, p < 0.001), accounting for 30% of score variance. Substantial variability in In-Service Examination-Qualifying Examination rankings was notable among individual residents. An In-Service Examination 2008 cutoff percentile rank of 40% identified chief residents in the lowest quartile on the Qualifying Examination 2009 with 71% sensitivity, 77% specificity, and a likelihood ratio of 3.1 and 0.4 (positive and negative likelihood ratios, respectively).
Conclusions: The substantial variability of In-Service Examination-Qualifying Examination performance among individual chief residents limits In-Service Examination predictive utility. A single In-Service Examination score should not be used to make a high stakes judgment about an individual resident. In-Service Examination scores should be used as 1 part of an overall evaluation program to prospectively identify residents who could benefit from additional educational support.

AB Lentiviruses likely infect nondividing cells by commandeering host nuclear transport factors to facilitate the passage of their preintegration complexes (PICs) through nuclear pore complexes (NPCs) within nuclear envelopes. Genome-wide small interfering RNA screens previously identified karyopherin beta transportin-3 (TNPO3) and NPC component nucleoporin 153 (NUP153) as being important for infection by human immunodeficiency virus type 1 (HIV-1). The knockdown of either protein significantly inhibited HIV-1 infectivity, while infection by the gammaretrovirus Moloney murine leukemia virus (MLV) was unaffected. Here, we establish that primate lentiviruses are particularly sensitive to NUP153 knockdown and investigate HIV-1-encoded elements that contribute to this dependency. Mutants lacking functional Vpr or the central DNA flap remained sensitive to NUP153 depletion, while MLV/HIV-1 chimera viruses carrying MLV matrix, capsid, or integrase became less sensitive when the latter two elements were substituted. Two capsid missense mutant viruses, N74D and P90A, were largely insensitive to NUP153 depletion, as was wild-type HIV-1 when cyclophilin A was depleted simultaneously or when infection was conducted in the presence of cyclosporine A. The codepletion of NUP153 and TNPO3 yielded synergistic effects that outweighed those calculated based on individual knockdowns, indicating potential interdependent roles for these factors during HIV-1 infection. Quantitative PCR revealed normal levels of late reverse transcripts, a moderate reduction of 2-long terminal repeat (2-LTR) circles, and a relatively large reduction in integrated proviruses upon NUP153 knockdown. These results suggest that capsid, likely by the qualities of its uncoating, determines whether HIV-1 requires cellular NUP153 for PIC nuclear import.

AB Although intracranial hemorrhage and infarction have been reported in patients with H1N1 influenza infection treated with extracorporeal membrane oxygenation (ECMO), the clinical outcomes of these patients are not well described.
The authors present two patients with H1N1 influenza infection and diffuse cerebrovascular injury in the setting of ECMO.
Diffuse cerebrovascular injury including intraparenchymal hemorrhage was found on head CT and brain MRI in both cases and confirmed by autopsy in one patient who died. Punctate foci of susceptibility effect were seen in both patients on T2* susceptibility-weighted or susceptibility-sensitive gradient echo sequences. These foci of susceptibility effect were consistent with infarction on histopathologic evaluation in the patient who died. The other patient made an excellent clinical recovery.
Frequent and early surveillance imaging should be obtained in patients with H1N1 influenza infection undergoing ECMO, although the presence of diffuse cerebral injury, including intraparenchymal hemorrhage and multifocal punctate susceptibility effect, does not necessarily portend a poor prognosis.

AB Increases in intracellular Ca(2+) during cellular stress often lead to the mitochondrial permeability transition (MPT). We examined changes in fatty acids (FAs) released from isolated renal cortical mitochondria subjected to Ca(2+)-induced MPT. Exposing mitochondria to Ca(2+) stimulated mitochondrial swelling and release of FAs such as arachidonic (20:4) and docosahexenoic acids which increased 71% and 32%, respectively, and linoleic (18:2) which decreased 23% compared to controls. Stearic (18:0), oleic (18:1), and linoleic (18:3) acids were unchanged. To elucidate a mechanism for FA release, mitochondria were pre-treated with bromoenolactone (BEL) to inhibit Ca(2+)-independent phospholipase A(2) gamma activity (iPLA(2)gamma). BEL blocked Ca(2+)-induced release of arachidonic and behenic (22:0) acids. Finally, four FAs were released in the absence of Ca(2+) in a BEL-sensitive manner, including arachidonic and docosatrienoic acids. Thus, extensive FA release occurs during Ca(2+)-induced MPT, and that mitochondrial iPLA(2)gamma maintains mitochondrial arachidonic acid homeostasis under both basal and Ca(2+)-induced stress conditions.

AB Objective MicroRNAs (miRNAs) regulate the expression of genes involved in immune activation. A study was undertaken to characterise the miRNA signature and identify novel genes involved in the regulation of immune responses in systemic lupus erythematosus (SLE).
Methods The expression of 365 miRNAs in peripheral blood mononuclear cells of patients with SLE and healthy controls was analysed using TaqMan Low Density Arrays. The results were validated by quantitative real-time PCR and potential target genes were identified using prediction analysis software. The effect of miR-21 on T cell function was assessed by transfection with antago-miR-21 or pre-miR-21.
Results A 27-miRNA signature was identified in patients with SLE; 19 miRNAs correlated with disease activity. Eight miRNAs were deregulated specifically in T cells and four miRNAs in B cells. miR-21 was upregulated and strongly correlated with SLE disease activity (r(2) = 0.92). Compared with controls, CD4 T lymphocytes from patients with SLE had higher basal and activation-induced miR-21 expression. Silencing of miR-21 reversed the activated phenotype of T cells from patients with SLE-namely, enhanced proliferation, interleukin 10 production, CD40L expression and their capacity to drive B cell maturation into Ig-secreting CD19+CD38(hi)IgD-(plasma cells. Overexpression of mMiR-21 in normal T cells led to acquisition of an activated phenotype. Investigation of putative gene-targets showed that PDCD4 (a selective protein translation inhibitor) was suppressed by miR-21 and its expression was decreased in active SLE.
Conclusions miRNAs represent potential biomarkers in SLE as their expression reflects underlying pathogenic processes and correlates with disease activity. Upregulated miR-21 affects PDCD4 expression and regulates aberrant T cell responses in human SLE.

AB Oral mucositis remains one of the most common and troubling side effects of standard chemoradiation regimens used for the treatment of head and neck cancer. Virtually all patients who receive cumulative radiation doses of more than 30Gy that includes oral mucosal fields will develop the condition. Not only does mucositis cause extreme discomfort, often necessitating opioid analgesia, but it is also associated with increased use of health resources and cost of treatment. The incremental cost of mucositis in patients with head and neck cancer is more than $17 000 (US). Much has been learned about the pathobiology that underlies the condition. The departure from the historical paradigm of direct cell death as being the primary cause for mucosal injury in favor of a more comprehensive view of the impact of chemoradiation on all the cells of the mucosa, has resulted in a picture of mucositis pathogenesis, which is biologically broad based. Although there are currently few treatment options for oral mucositis at the moment, the recognition that its underlying biology is complex has provided a range of treatment options that are currently being developed.

AB The concept of immunotherapy as a treatment for cancer patients has been in existence for decades. However, more recent immune therapeutic approaches have involved targeting of tumor-specific antigens. Although improvements have been made in using such immune stimulatory treatment strategies for a variety of solid cancers, the use of these strategies for patients with head and neck squamous cell carcinoma (HNSCC) is lagging behind. Immunotherapeutic approaches for HNSCC are particularly complicated by the profound immune suppression that is induced by HNSCC, which potentially decreases the effectiveness of immune stimulatory efforts. Trials involving patients with various solid cancers have shown the enhanced effectiveness of combining various immunotherapeutic approaches or combining immunotherapy with chemotherapy or radiation therapy. Treatment of HNSCC with such combination approaches has not been extensively investigated and has the added challenge of the need to overcome the HNSCC-induced immune suppression. This study focuses on clinical trials that have tested immunotherapeutic approaches for HNSCC patients and the challenges associated with such approaches. In addition, it will call attention to immunotherapeutic strategies that have been shown to be successful in the treatment of other solid cancers to identify potential strategies that may apply to the treatment of HNSCC.

AB Induced pluripotent stem cells (iPSCs) hold great promise for cell therapies and tissue engineering. Neural crest stem cells (NCSCs) are multipotent and represent a valuable system to investigate iPSC differentiation and therapeutic potential. Here we derived NCSCs from human iPSCs and embryonic stem cells (ESCs), and investigated the potential of NCSCs for neural tissue engineering. The differentiation of iPSCs and the expansion of derived NCSCs varied in different cell lines, but all NCSC lines were capable of differentiating into mesodermal and ectodermal lineages, including neural cells. Tissue-engineered nerve conduits were fabricated by seeding NCSCs into nanofibrous tubular scaffolds, and used as a bridge for transected sciatic nerves in a rat model. Electrophysiological analysis showed that only NCSC-engrafted nerve conduits resulted in an accelerated regeneration of sciatic nerves at 1 month. Histological analysis demonstrated that NCSC transplantation promoted axonal myelination. Furthermore, NCSCs differentiated into Schwann cells and were integrated into the myelin sheath around axons. No teratoma formation was observed for up to 1 year after NCSC transplantation in vivo. This study demonstrates that iPSC-derived multipotent NCSCs can be directly used for tissue engineering and that the approach that combines stem cells and scaffolds has tremendous potential for regenerative medicine applications.

AB Immunostimulatory therapies that activate immune response pathways are of great interest for overcoming the immunosuppression present in advanced tumors. Agonistic anti-CD40 antibodies and CpG oligonucleotides have previously demonstrated potent, synergistic anti-tumor effects, but their clinical use even as monotherapies is hampered by dose-limiting inflammatory toxicity provoked upon systemic exposure. We hypothesized that by anchoring immuno-agonist compounds to lipid nanoparticles we could retain the bioactivity of therapeutics in the local tumor tissue and tumor-draining lymph node, but limit systemic exposure to these potent molecules. We prepared PEGylated liposomes bearing surface-conjugated anti-CD40 and CpG and assessed their therapeutic efficacy and systemic toxicity compared to soluble versions of the same immuno-agonists, injected intratumorally in the B16F10 murine model of melanoma. Anti-CD40/CpG-liposomes significantly inhibited tumor growth and induced a survival benefit similar to locally injected soluble anti-CD40 + CpG. Biodistribution analyses following local delivery showed that the liposomal carriers successfully sequestered anti-CD40 and CpG in vivo, reducing leakage into systemic circulation while allowing draining to the tumor-proximal lymph node. Contrary to locally-administered soluble immunotherapy, anti-CD40/CpG-liposomes did not elicit significant increases in serum levels of ALT enzyme, systemic inflammatory cytokines, or overall weight loss, confirming that off-target inflammatory effects had been minimized. The development of a delivery strategy capable of inducing robust anti-tumor responses concurrent with minimal systemic side effects is crucial for the continued progress of potent immunotherapies toward widespread clinical translation.

AB The goal of this study was to design and develop a myocardial patch to use in the repair of myocardial infarctions or to slow down tissue damage and improve long-term heart function. The basic 3D construct design involved two biodegradable macroporous tubes, to allow transport of growth media to the cells within the construct, and cell seeded, aligned fiber mats wrapped around them. The microfibrous mat housed mesenchymal stem cells (MSCs) from human umbilical cord matrix (Wharton's Jelly) aligned in parallel to each other in a similar way to cell organization in native myocardium. Aligned micron-sized fiber mats were obtained by electrospinning a polyester blend (PHBV (5% HV), P(L-D,L)LA (70:30) and poly(glycerol sebacate) (PGS)). The micron-sized electrospun parallel fibers were effective in Wharton's Jelly (WJ) MSCs alignment and the cells were able to retract the mat. The 3D construct was cultured in a microbioreactor by perfusing the growth media transiently through the macroporous tubing for two weeks and examined by fluorescence microscopy for cell distribution and preservation of alignment. The fluorescence images of thin sections of 3D constructs from static and perfused cultures confirmed enhanced cell viability, uniform cell distribution and alignment due to nutrient provision from inside the 3D structure.

AB Osteolysis due to wear of UHMWPE limits the longevity of joint arthroplasty. Oxidative degradation of UHMWPE gamma-sterilized in air increases its wear while decreasing mechanical strength. Vitamin E stabilization of UHMWPE was proposed to improve oxidation resistance while maintaining wear resistance and fatigue strength.
We reviewed the preclinical research on the development and testing of vitamin E-stabilized UHMWPE with the following questions in mind: (1) What is the rationale behind protecting irradiated UHMWPE against oxidation by vitamin E? (2) What are the effects of vitamin E on the microstructure, tribologic, and mechanical properties of irradiated UHMWPE? (3) Is vitamin E expected to affect the periprosthetic tissue negatively?
We performed searches in PubMed, Scopus, and Science Citation Index to review the development of vitamin E-stabilized UHMWPEs and their feasibility as clinical implants.
The rationale for using vitamin E in UHMWPE was twofold: improving oxidation resistance of irradiated UHMWPEs and fatigue strength of irradiated UHMWPEs with an alternative to postirradiation melting. Vitamin E-stabilized UHMWPE showed oxidation resistance superior to that of irradiated UHMWPEs with detectable residual free radicals. It showed equivalent wear and improved mechanical strength compared to irradiated and melted UHMWPE. The biocompatibility was confirmed by simulating elution, if any, of the antioxidant from implants.
Vitamin E-stabilized UHMWPE offers a joint arthroplasty technology with good mechanical, wear, and oxidation properties.
Vitamin E-stabilized, irradiated UHMWPEs were recently introduced clinically. The rationale behind using vitamin E and in vitro tests comparing its performance to older materials are of great interest for improving longevity of joint arthroplasties.

AB The question of how to optimally organize into chapters and label the different categories of mental disorders is an important one for DSM-5 and ICD-11. The grouping of mental disorders, or meta-structure, should arguably reflect knowledge on the validity of different conditions and their relationships, and should ideally contribute to improving the clinical utility of the nosology by guiding clinical assessment and management. The DSM-5 Anxiety, Obsessive-Compulsive Spectrum, Posttraumatic, and Dissociative Disorders Workgroup has reviewed the nature of anxiety disorders, the possibility of including a new category of obsessive-compulsive spectrum disorders in the DSM-5, and the concept of traumatic stress disorders. It is difficult to devise a perfect nosology that dissects nature at her joints; instead, any particular approach to the meta-structure would seem to have pros and cons that must be carefully weighed. Despite the imperfections of any meta-structure, we are hopeful that each revision of the nosology will bring with it greater diagnostic validity and clinical utility.

AB To prospectively examine coronary artery plaques as predictors of myocardial ischaemia using cardiac magnetic resonance (CMR).
Fifty-two patients (46 men; age 64 +/- 10) with suspected coronary artery disease (CAD) referred for catheter coronary angiography (CA) underwent CMR and computed tomography coronary angiography (CTCA). All coronary segments were evaluated for morphological stenosis based on CA. Any plaque according to its composition was assessed based on CTCA.
Numbers of total and calcified coronary artery plaques represented the best predictors of myocardial ischaemia (AUC = 0.87; [95%CI: 0.77-0.97] and AUC = 0.87; [95%CI: 0.77-0.96], respectively, p = 0.56) with the total plaque number significantly higher in patients with corresponding ischaemia than those without (p < 0.01, p < 0.05 adjusted for pre-test probability and stenosis). Compared with the AUC of coronary stenosis assessment by CA (AUC = 0.90; [95%CI: 0.80-1.00]), AUCs were equivalent using either the total number or the number of calcified plaques alone (p = 0.73 and p = 0.69). Multivariate logistic regression analyses demonstrated the total plaque number as an independent predictor of ischaemia (odds +20%; [95%CI: 1.096-1.368]), improving a model including clinical probability estimates of CAD (c-statistics, 0.66 to 0.89).
Coronary artery plaque number according to CTCA is a significant, independent predictor of myocardial ischaemia with similar accuracy to stenosis assessment.

AB Introduction: Prostate cancer vaccines attempt to induce cancer-specific systemic immune responses and represent a new class of targeted therapies, many of which are non-toxic. Several vaccine technologies are in development.
Areas covered: An autologous antigen presenting cell vaccine loaded with prostate acid phosphatase conjugated with GM-CSF, sipuleucel-T confers a survival advantage in men with metastatic castration-resistant prostate cancer (CRPC) and is now FDA approved based on the IMPACT trial. A poxvirus-based vaccine, PROSTVAC-VF TRICOM targeting prostate-specific antigen (PSA), has demonstrated improved survival in a randomized Phase II trial of patients with metastatic CRPC. Novel T lymphocyte checkpoint inhibitors of cytotoxic T lymphocyte antigen 4 and programmed death-1 are also emerging. Recognition of improved survival without an earlier clinical signal of activity by conventional criteria has led to new guidelines to evaluate immunotherapeutic agents. The clinical benefit of combining vaccines with chemotherapy, radiotherapy and other immunotherapeutic and biologic agents is being evaluated in the context of disappointing results of combination GVAX vaccine and docetaxel chemotherapy.
Expert opinion: To build on the success of early phase trials, efforts must be made to optimize vaccine approaches and patient selection.

AB Follicular dendritic cells (FDC) are an important subset of stromal cells within the germinal centres of lymphoid tissues. They are specialized to trap and retain antigen-containing immune complexes on their surfaces to promote B-cell maturation and immunoglobulin isotype class-switching. However, little is known of the cell types from which FDC originate. To address fundamental questions associated with the relationships between FDC and other cell populations, we took advantage of the growing body of publicly available data for transcriptome analysis. We obtained a large number of gene expression data files from a range of different primary mouse cells and cell lines and subjected these data to network-based cluster analysis using BIOLAYOUT EXPRESS(3D). Genes with related function clustered together in distinct regions of the graph and enabled the identification of transcriptional networks that underpin the functional activity of distinct cell populations. Several gene clusters were identified that were selectively expressed by cells of mesenchymal lineage and contained classic mesenchymal cell markers and extracellular matrix genes including various collagens, Acta2, Bgn, Fbn1 and Twist1. Our analysis showed that FDC also express highly many of these mesenchyme-associated genes. Promoter analysis of the genes comprising the mesenchymal clusters identified several regulatory motifs that are binding sites for candidate transcription factors previously known to be candidate regulators of mesenchyme-specific genes. Together, these data suggest FDC are a specialized mesenchymal cell population within the germinal centres of lymphoid tissues.

TI TAK1 Expression in the Cochlea: A Specific Marker for Adult Supporting

AB Transforming growth factor-beta-activated kinase-1 (TAK1) is a mitogen activated protein kinase kinase kinase that is involved in diverse biological roles across species. Functioning downstream of TGF-beta and BMP signaling, TAK1 mediates the activation of the c-Jun N-terminal kinase signaling pathway, serves as the target of pro-inflammatory cytokines, such as TNF-alpha, mediates NF-kappa I(2) activation, and plays a role in Wnt/Fz signaling in mesenchymal stem cells. Expression of TAK1 in the cochlea has not been defined. Data mining of previously published murine cochlear gene expression databases indicated that TAK1, along with TAK1 interacting proteins 1 (TAB1), and 2 (TAB2), is expressed in the developing and adult cochlea. The expression of TAK1 in the developing cochlea was confirmed using RT-PCR and immunohistochemistry. Immunolabeling of TAK1 in embryonic, neonatal, and mature cochleas via DAB chromogenic and fluorescent immunohistochemistry indicated that TAK1 is broadly expressed in both the developing otocyst and periotic mesenchyme at E12.5 but becomes more restricted to specific types of supporting cells as the organ of Corti matures. By P1, TAK1 immunolabeling is found in cells of the stria vascularis, hair cells, supporting cells, and Kolliker's organ. By P16, TAK1 labeling is limited to cochlear supporting cells. In the adult cochlea, TAK1 immunostaining is only present in the cytoplasm of Deiters' cells, pillar cells, inner phalangeal cells, and inner border cells, with no expression in any other cochlear cell types. While the role of TAK1 in the inner ear is unclear, TAK1 expression may be used as a novel marker for specific sub-populations of supporting cells.

AB Antibodies form an important class of cancer therapeutics, and there is intense interest in using them for imaging applications in diagnosis and monitoring of cancer treatment. Despite the expanding body of knowledge describing pharmacokinetic and pharmacodynamic interactions of antibodies in vivo, discrepancies remain over the effect of antigen expression level on tumoral uptake with some reports indicating a relationship between uptake and expression and others showing no correlation.
Using a cell line with high epithelial cell adhesion molecule expression and moderate epidermal growth factor receptor expression, fluorescent antibodies with similar plasma clearance were imaged in vivo. A mathematical model and mouse xenograft experiments were used to describe the effect of antigen expression on uptake of these high-affinity antibodies.
As predicted by the theoretical model, under subsaturating conditions, uptake of the antibodies in such tumors is similar because localization of both probes is limited by delivery from the vasculature. In a separate experiment, when the tumor is saturated, the uptake becomes dependent on the number of available binding sites. In addition, targeting of small micrometastases is shown to be higher than larger vascularized tumors.
These results are consistent with the prediction that high affinity antibody uptake is dependent on antigen expression levels for saturating doses and delivery for subsaturating doses. It is imperative for any probe to understand whether quantitative uptake is a measure of biomarker expression or transport to the region of interest. The data provide support for a predictive theoretical model of antibody uptake, enabling it to be used as a starting point for the design of more efficacious therapies and timely quantitative imaging probes.

AB BACKGROUND. The influence of PSA kinetics on the outcome of metastatic prostate cancer after androgen deprivation therapy (ADT) is not well understood. We evaluated the prognostic significance of PSA nadir and time to PSA nadir as well as their potential interactive effect on the progression of disease after ADT.
METHODS. A total of 650 men with advanced or metastatic prostate cancer treated with ADT were studied. The prognostic significance of PSA nadir and time to PSA nadir on disease progression were analyzed using Kaplan-Meier analysis and the Cox regression model.
RESULTS. We found that both PSA nadir and time to PSA nadir were independent and significant predictors of disease progression. Patients with higher PSA nadir (>= 0.2 ng/ml) and shorter time to PSA nadir (< 10 months) had significant shorter time to disease progression after adjusting for other covariates. The combined analyses showed a potential synergistic effect of these two variables on disease progression. Patient with higher PSA nadir and shorter time to PSA nadir had significantly higher risk for disease progression compared to those with lower PSA nadir and longer time to PSA nadir (Hazard Ratios (HR) = 3.11, P<0.001).
CONCLUSIONS. We concluded that both PSA nadir and time to PSA nadir are significant predictors of disease progression for prostate cancer patients receiving ADT. Prostate 71: 1189-1197, 2011. (C) 2011 Wiley-Liss, Inc.

AB The vasopressin type 2 (V2R) receptor belongs to the class of G-protein coupled receptors. It is mainly expressed in the membrane of kidney tubules, where it is activated by the extracellular arginine vasopressin. In men, inactivating and activating mutations cause nephrogenic diabetes insipidus and the nephrogenic syndrome of inappropriate antidiuresis respectively. Like most GPCRs, V2R's third intracellular loop (V2R-i3) is involved in the binding and activation of its major effector, the G alpha S protein. We overexpressed the V2R(224-274) fragment corresponding to V2R-i3 as a fusion protein with thioredoxin A at the N-terminus and a hexahistidine tag between the two proteins. Recombinant V2R-i3 was designed to harbor N- and C-terminal cysteines, in order to introduce a disulfide bond between N- and C-terminal extremities and hence reproduce the hairpin fold presumably present in the full-length receptor. The fusion protein was produced as inclusion bodies in Escherichia coli and purified by nickel affinity chromatography under denaturing conditions. After a refolding step, thioredoxin and hexahistidine tags were specifically cleaved with the tobacco etch virus protease. The hydrolysis yield, initially very low, increased up to 80% thanks to optimization of buffers and refolding methods. The cleaved fragment, V2(224-274), devoid of any tag, was then eluted with low imidazole concentrations in a second nickel affinity chromatography in denaturing conditions. The final yield was sufficient to prepare a (15)N-(13)C labeled NMR sample suitable for triple resonance experiments. We assigned all NMR resonances and confirmed the correct peptide sequence. As expected, the peptide forms a hairpin stabilized by a disulfide bond between its N- and C-terminal parts, thus mimicking its native structure in the full-length receptor. This study may provide a strategy for producing and studying the structure/function relationship of GPCR fragments. (C) 2011 Elsevier Inc. All rights reserved.

AB Purpose This paper assesses interscan, interreader, and intrareader variability of C-arm CT and compares it to that of flat-panel volume-CT (fpVCT) and high-definition multi-detector-CT (HD-MDCT).
Methods Five cadaver knee specimens were imaged using C-arm-CT, fpVCT, and HD-MDCT. Apparent (app.) trabecular bone volume fraction (BV/TV), app. trabecular number (TbN), app. trabecular spacing (TbSp), and app. trabecular thickness (TbTh) of the proximal tibia were measured by three readers. Interreader, intrareader, and interscan variability for C-arm CT was expressed as coefficient of variation (CV), standard deviation (SD), and intraclass correlation coefficient (ICC).
Results With the exception of app.TbSp (CV: 7.05-9.35%, SD: 0.06-0.09, ICC: 0.89-0.94), the variability of C-arm CT was low (CV: 2.41-6.43%, SD: 0.01-0.048, ICC: 0.65-0.98). Its interreader reliability (CV: 2.66-4.55%, SD: 0.01-0.03, ICC: 0.81-0.95) was comparable to that of HD-MDCT (CV: 2.41-4.08%, SD: 0.014-0.016, ICC: 0.95-0.96), and fpVCT (CV: 3.13-5.63%, SD: 0.009-0.036, ICC: 0.64-0.98) for all parameters except app.TbSp.
Conclusions C-arm CT is a reliable method for assessing trabecular bone architectural parameters with the exception of app.TbSp due to spatial resolution limitation.

In nephropathy, associated with diabetes, increased Akt signal transduction results in glomerular especially mesangial cell hypertrophy. The mechanism of Akt activation by elevated glucose is poorly understood. The oncogene DJ-1 prevents oxidative damage and apoptosis of dopaminergic neurons in animal models of Parkinson's disease and in culture. We identified DJ-1 to increase in response to high glucose in renal glomerular mesangial cells concomitant with an increase in phosphorylation of Akt in a time-dependent manner. Plasmid-derived overexpression as well as down-regulation of DJ-1 by siRNA showed the requirement of this protein in high glucose-stimulated Akt phosphorylation. The tumor suppressor protein PTEN acts as a negative regulator of Akt activation. Interestingly, DJ-1 was associated with PTEN and this interaction was significantly increased in response to high glucose. High glucose-induced increase in DJ-1 promoted phosphorylation of the PRAS40, a negative regulator of TORC1 kinase activity, resulting in activating and inactivating phosphorylation of S6 kinase and 4EBP-1, respectively. Furthermore, DJ-1 increased protein synthesis and hypertrophy of mesangial cells. Our results provide evidence for a unique mechanism whereby DJ-1 induces Akt/PRAS40/TORC1-mediated hypertrophy in response to high glucose. (C) 2011 Elsevier Inc. All rights reserved.

AB Detailed characterization of the cancer genome in a large number of primary human glioblastomas has identified recurrent alterations that result in deregulation of signal transduction pathways and are "druggable" with a growing number of small molecule pharmaceuticals. While many of these compounds have shown clinical activity in other human cancers harboring similar genetic alterations, the clinical experience in glioblastoma has been disappointing thus far with only rare and transient radiographic responses. Our understanding of drug resistance is confounded by the uncertainty of drug delivery across the blood brain barrier and the limited knowledge to what extent the growth of these tumors depends on any particular signaling pathway. This uncertainty is, at least in part, due to shortcomings in the current approach to evaluate signal transduction inhibitors in glioma patients, including drug testing in molecularly unselected patient populations, limited documentation of drug penetration and target inhibition in tumor tissue, and use of radiographic response criteria that may not be optimal for the evaluation of these compounds.

AB The purpose of this study is to test whether ectopic expression of Sox-9 can induce adipose tissue-derived stem cells (ASCs) to function as real nucleus pulposus (NP) cells in vitro. Adenoviral vectors expressing Sox-9 were reported to infect the chondroblastic and human disc cells, which resulted in increased Sox-9 and type II collagen production. ASCs were isolated from rat inguinal adipose pad, characterized, and transduced in vitro with a retroviral vector encoding the Sox-9 gene. Sox-9-engineered ASCs (ASCs/Sox-9) were induced for the chondrocyte-like cell differentiation by 3D cultured in alginate beads and TGF-beta 3 for 2 weeks. Expression of exogenous Sox-9 protein was detected. Type II collagen and Aggrecan gene expressions of induced ASCs/Sox-9 were measured using real-time PCR; proteoglycans expressions were measured by checking the glycosaminoglycan content and type II collagen production by enzyme-linked immunosorbent assay. Isolated ASCs were CD 29(+)/CD44(+)/C-Kit(-)/Lin(-)/CD34(-)/CD45(-). ASCs/Sox-9 expressed marked increase in exogenous Sox-9 protein. After induction, type II collagen gene expression was sevenfold higher in mRNA levels, with an approximately twofold increase in protein levels of ASCs/Sox-9 compared to ASCs. Type II collagen and proteoglycan productions were significantly increased in the ASCs/Sox-9 compared to the ASCs. In addition, co-culture of induced ASCs/Sox-9 with matured NP cells resulted in enhanced increase in proteoglycan and type II collagen production. Constitutive retroviral expression of Sox-9 could efficiently induce ASCs differentiation into chondrocyte-like cells. This novel approach may provide a practicable system for a simple and rapid differentiation of ASCs into chondrocyte-like cells which may be potentially used as a stem cell-based therapeutic tool for the treatment of degenerative disc diseases.

AB Human imaging studies examining fear conditioning have mainly focused on the neural responses to conditioned cues. In contrast, the neural basis of the unconditioned response and the mechanisms by which fear modulates inter-regional functional coupling have received limited attention. We examined the neural responses to an unconditioned stimulus using a partial-reinforcement fear conditioning paradigm and functional MRI. The analysis focused on: (1) the effects of an unconditioned stimulus (an electric shock) that was either expected and actually delivered, or expected but not delivered, and (2) on how related brain activity changed across conditioning trials, and (3) how shock expectation influenced interregional coupling within the fear network. We found that: (1) the delivery of the shock engaged the red nucleus, amygdale, dorsal striatum, insula, somatosensory and cingulate cortices, (2) when the shock was expected but not delivered, only the red nucleus, the anterior insular and dorsal anterior cingulate cortices showed activity increases that were sustained across trials, and (3) psycho-physiological interaction analysis demonstrated that fear led to increased red nucleus coupling to insula but decreased hippocampus coupling to the red nucleus, thalamus and cerebellum. The hippocampus and the anterior insula may serve as hubs facilitating the switch between engagement of a defensive immediate fear network and a resting network. (C) 2011 Elsevier B.V.

AB The honeybee, Apis mellifera L (Hymenoptera: Apidae), has recently become a model for studying brain asymmetry among invertebrates. A strong lateralization favouring the right antenna was discovered in odour learning and short-term memory recall experiments, and a lateral shift favouring the left antenna for long-term memory recall. Corresponding morphological asymmetries have been found in the distribution of olfactory sensilla between the antennae and confirmed by electrophysiological odour response measurements in isolated right and left antennae. The aim of this study was to investigate whether a morphological asymmetry can be observed in the volume of the primary olfactory centres of the central nervous system, the antennal lobes (ALs). Precise volume measurements of a subset of their functional units, the glomeruli, were performed in both sides of the brain, exploiting the advantages of two-photon microscopy. This novel method allowed minimal invasive acquisition of volume images of the ALs, avoiding artefacts from brain extraction and dehydration. The study was completed by a series of behavioural experiments in which response asymmetry in odour recall following proboscis extension reflex conditioning was assessed for odours, chosen to stimulate strong activity in the same glomeruli as in the morphological study. The volumetric measurements found no evidence of lateralization in the investigated glomeruli within the experimental limits. Instead, in the behavioural experiments, a striking odour dependence of the lateralization was observed. The results are discussed on the basis of recent neurophysiological and ethological experiments in A. mellifera. (C) 2011 Elsevier BM. All rights reserved.

AB Neuropathic pain is generally defined as a chronic pain state resulting from peripheral and/or central nerve injury. Effective treatment for neuropathic pain is still lacking, due in part to poor understanding of pathological mechanisms at the molecular level. Neuronal mechanisms of neuropathic pain, especially synaptic plasticity, are the major focus of many investigators. N-methyl-D-aspartate (NMDA) receptor dependent synaptic plasticity at the spinal and cortical levels is believed to contribute to enhanced sensory responses after injury. Glial cells, including astrocytes and microglia, have recently been implicated in neuropathic pain. These glial cells form close interactions with neurons and thus may modulate nociceptive transmission under pathological conditions. In this review, we present recent progress in the study of neuronal and microglial mechanisms underlying neuropathic pain. We propose that activity-dependent neuronal plasticity is a key target for treatment in neuropathic pain.

AB The Wisconsin Card Sorting Test (WCST) is a set-switching task used extensively to study impaired executive functioning in schizophrenia. Declarative memory deficits have also been associated with schizophrenia and may affect WCST performance because continued correct responding depends on remembering the outcome of previous responses. This study examined whether performance in visual and verbal declarative memory tasks were associated with WCST performance. Subjects comprised 30 patients with schizophrenia or schizoaffective disorder (SCZ) and 30 demographically matched healthy controls (CON) who were tested on the WCST, the Benton Visual Retention Test (BVRT), the California Verbal Learning Test (CVLT), and the Continuous Performance Test (CPT). SCZ subjects showed significant correlations between visual and verbal declarative memory and performance on the WCST-64 that were in the hypothesized direction such that worse memory performance was associated with worse performance on the WCST. CON subjects did not show a significant relationship between visual or verbal memory and WCST-64 performance. Fisher's r to z transformations indicated that the associations between declarative memory and WCST-64 performance in the SCZ subjects differed significantly from those of CON subjects. The findings suggest that interpretations of WCST-64 scores for subjects with schizophrenia should be considered in light of their declarative memory functioning.

AB Exposure to to smoking cues increases craving to smoke and negatively changes mood in smokers with schizophrenia (SWS). This pilot study compared reactivity to real-world smoking environments versus neutral environments in SWS (n=10) and non-psychiatric control smokers (CON; n=10). Results indicate that both SWS and CON experienced increases in smoking urges when viewing images of their smoking environments and that SWS tended to report greater increases in withdrawal-related negative mood than CON when viewing images of their smoking environments. These findings signify that personalized smoking environments trigger smoking urges in SWS and suggest that extinguishing this reactivity may aid cessation efforts in this population.

AB Alterations in working memory, default-mode network (DMN), and dopamine transporter have all been proposed as endophenotypes for attention-deficit/hyperactivity disorder (ADHD). Despite evidence that these systems are interrelated, their relationship to each other has never been studied in the context of ADHD. In order to understand the potential mediating effects of task-positive and task-negative networks between DAT1 and diagnosis, we tested effects of genotype and diagnosis on regions of positive and negative BOLD signal change (as measured with fMRI) in 53 adults with ADHD and 38 control subjects during a working memory task. We also examined the relationship of these responses to ADHD symptoms. Our results yielded four principal findings: 1) association of the DAT1 9R allele with adult ADHD, 2) marginal DAT1 association with task-related suppression in left medial PFC, 3) marginal genotype x diagnosis interaction in the dorsal anterior cingulate cortex, and 4) correlation of DMN suppression to ADHD symptoms. These findings replicate the association of the 9R allele with adult ADHD. Further, we show that DMN suppression is likely linked to DAT1 and to severity of inattention in ADHD. DMN may therefore be a target of DAT1 effects, and lie on the path between the gene and inattention in ADHD. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

AB We discovered a class of naturally occurring human proteins with unusually high net positive charge that can potently deliver proteins in functional form into mammalian cells both in vitro and also in murine retina, pancreas, and white adipose tissues in vivo. These findings represent diverse macromolecule delivery agents for in vivo applications, and also raise the possibility that some of these human proteins may penetrate cells as part of their native biological functions.

AB Selective protein kinase inhibitors have only been developed against a small number of kinase targets. Here we demonstrate that "high-throughput kinase profiling" is an efficient method for the discovery of lead compounds for established as well as unexplored kinase targets. We screened a library of 118 compounds constituting two distinct scaffolds (furan-thiazolidinediones and pyrimido-diazepines) against a panel of 353 kinases. A distinct kinase selectivity profile was observed for each scaffold. Selective inhibitors were identified with submicromolar cellular activity against PIM1, ERK5, ACK1, MPS1, PLK1-3, and Aurora A,B kinases. In addition, we identified potent inhibitors for so far unexplored kinases such as DRAK1, HIPK2, and DCAMKL1 that await further evaluation. This inhibitor-centric approach permits comprehensive assessment of a scaffold of interest and represents an efficient and general strategy for identifying new selective kinase inhibitors.

AB Target identification remains challenging for the field of chemical biology. We describe an integrative chemical genomic and proteomic approach combining the use of differentially active analogs of small molecule probes with stable isotope labeling by amino acids in cell culture-mediated affinity enrichment, followed by subsequent testing of candidate targets using RNA interference-mediated gene silencing. We applied this approach to characterizing the natural product K252a and its ability to potentiate neuregulin-1 (Nrg1)/ErbB4 (v-erb-a erythroblastic leukemia viral oncogene homolog 4)-dependent neurotrophic factor signaling and neuritogenesis. We show that AAK1 (adaptor-associated kinase 1) is a relevant target of K252a, and that the loss of AAK1 alters ErbB4 trafficking and expression levels, providing evidence for a previously unrecognized role for AAK1 in Nrg1 -mediated neurotrophic factor signaling. Similar strategies should lead to the discovery of novel targets for therapeutic development.

AB Non-opsonic phagocytosis is a primordial form of pathogen recognition that is mediated by the direct interaction of phagocytic receptors with microbial surfaces. In the fruit fly Drosophila melanogaster, the EGF-like repeat containing scavenger receptor Eater is expressed by phagocytes and is required to survive infections with Gram-positive and Gram-negative bacteria. However, the mechanisms by which this receptor recognizes different types of bacteria are poorly understood. To address this problem, we generated a soluble, Fc-tagged receptor variant of Eater comprising the N-terminal 199 amino acids including four EGF-like repeats. We first established that Eater-Fc displayed specific binding to broad yet distinct classes of heat- or ethanol-inactivated microbes and behaved similarly to the membrane-bound, full-length Eater receptor. We then used Eater-Fc as a tool to probe Eater binding to the surface of live bacteria. Eater-Fc bound equally well to naive or inactivated Staphylococcus aureus or Enterococcus faecalis, suggesting that in vivo, Eater directly targets live Gram-positive bacteria, enabling their phagocytic clearance and destruction. By contrast, Eater-Fc was unable to interact with live, naive Gram-negative bacteria (Escherichia coli, Serratia marcescens, and Pseudomonas aeruginosa). For these bacteria, Eater-Fc binding required membrane-disrupting treatments. Furthermore, we found that cecropin A, a cationic, membrane-disrupting antimicrobial peptide, could promote Eater-Fc binding to live E. coli, even at sublethal concentrations. These results suggest a previously unrecognized mechanism by which antimicrobial peptides cooperate with phagocytic receptors to extend the range of microbes that can be targeted by a single, germline-encoded receptor.

TI Oral Microbiome Profiles: 16S rRNA Pyrosequencing and Microarray Assay
Comparison
SO PLOS ONE
LA English
DT Article
ID PERIODONTITIS; MICROFLORA; SEQUENCES; PROJECT
AB Objectives: The human oral microbiome is potentially related to diverse health conditions and high-throughput technology provides the possibility of surveying microbial community structure at high resolution. We compared two oral microbiome survey methods: broad-based microbiome identification by 16S rRNA gene sequencing and targeted characterization of microbes by custom DNA microarray.
Methods: Oral wash samples were collected from 20 individuals at Memorial Sloan-Kettering Cancer Center. 16S rRNA gene survey was performed by 454 pyrosequencing of the V3-V5 region (450 bp). Targeted identification by DNA microarray was carried out with the Human Oral Microbe Identification Microarray (HOMIM). Correlations and relative abundance were compared at phylum and genus level, between 16S rRNA sequence read ratio and HOMIM hybridization intensity.
Results: The major phyla, Firmicutes, Proteobacteria, Bacteroidetes, Actinobacteria, and Fusobacteria were identified with high correlation by the two methods (r = 0.70 similar to 0.86). 16S rRNA gene pyrosequencing identified 77 genera and HOMIM identified 49, with 37 genera detected by both methods; more than 98% of classified bacteria were assigned in these 37 genera. Concordance by the two assays (presence/absence) and correlations were high for common genera (Streptococcus, Veillonella, Leptotrichia, Prevotella, and Haemophilus; Correlation = 0.70-0.84).
Conclusion: Microbiome community profiles assessed by 16S rRNA pyrosequencing and HOMIM were highly correlated at the phylum level and, when comparing the more commonly detected taxa, also at the genus level. Both methods are currently suitable for high-throughput epidemiologic investigations relating identified and more common oral microbial taxa to disease risk; yet, pyrosequencing may provide a broader spectrum of taxa identification, a distinct sequence-read record, and greater detection sensitivity.

AB Plants generate effective responses to infection by recognizing both conserved and variable pathogen-encoded molecules. Pathogens deploy virulence effector proteins into host cells, where they interact physically with host proteins to modulate defense. We generated an interaction network of plant-pathogen effectors from two pathogens spanning the eukaryote-eubacteria divergence, three classes of Arabidopsis immune system proteins, and similar to 8000 other Arabidopsis proteins. We noted convergence of effectors onto highly interconnected host proteins and indirect, rather than direct, connections between effectors and plant immune receptors. We demonstrated plant immune system functions for 15 of 17 tested host proteins that interact with effectors from both pathogens. Thus, pathogens from different kingdoms deploy independently evolved virulence proteins that interact with a limited set of highly connected cellular hubs to facilitate their diverse life-cycle strategies.

AB Plants have unique features that evolved in response to their environments and ecosystems. A full account of the complex cellular networks that underlie plant-specific functions is still missing. We describe a proteome-wide binary protein-protein interaction map for the interactome network of the plant Arabidopsis thaliana containing about 6200 highly reliable interactions between about 2700 proteins. A global organization of plant biological processes emerges from community analyses of the resulting network, together with large numbers of novel hypothetical functional links between proteins and pathways. We observe a dynamic rewiring of interactions following gene duplication events, providing evidence for a model of evolution acting upon interactome networks. This and future plant interactome maps should facilitate systems approaches to better understand plant biology and improve crops.

AB Quantitative cross-sectional imaging of vocal folds during phonation is potentially useful for diagnosis and treatments of laryngeal disorders. Optical coherence tomography (OCT) is a powerful technique, but its relatively low frame rates makes it challenging to visualize rapidly vibrating tissues. Here, we demonstrate a novel method based on triggered laser scanning to capture 4-dimensional (4D) images of samples in motu at audio frequencies over 100 Hz. As proof-of-concept experiments, we applied this technique to imaging the oscillations of biopolymer gels on acoustic vibrators and aerodynamically driven vibrations of the vocal fold in an ex vivo calf larynx model. Our results suggest that triggered 4D OCT may be useful in understanding and assessing the function of vocal folds and developing novel treatments in research and clinical settings.

AB Background: Genome scale expression profiling of human tumor samples is likely to yield improved cancer treatment decisions. However, identification of clinically predictive or prognostic classifiers can be challenging when a large number of genes are measured in a small number of tumors.
Results: We describe an unsupervised method to extract robust, consistent metagenes from multiple analogous data sets. We applied this method to expression profiles from five "double negative breast cancer" (DNBC) (not expressing ESR1 or HER2) cohorts and derived four metagenes. We assessed these metagenes in four similar but independent cohorts and found strong associations between three of the metagenes and agent-specific response to neoadjuvant therapy. Furthermore, we applied the method to ovarian and early stage lung cancer, two tumor types that lack reliable predictors of outcome, and found that the metagenes yield predictors of survival for both.
Conclusions: These results suggest that the use of multiple data sets to derive potential biomarkers can filter out data set-specific noise and can increase the efficiency in identifying clinically accurate biomarkers.

AB In a zebrafish mutagenesis screen to identify genes essential for myelopoiesis, we identified an insertional allele hi1727, which disrupts the gene encoding RNA helicase dead-box 18 (Ddx18). Homozygous Ddx18 mutant embryos exhibit a profound loss of myeloid and erythroid cells along with cardiovascular abnormalities and reduced size. These mutants also display prominent apoptosis and a G1 cell-cycle arrest. Loss of p53, but not Bcl-xl overexpression, rescues myeloid cells to normal levels, suggesting that the hematopoietic defect is because of p53dependent G1 cell-cycle arrest. We then sequenced primary samples from 262 patients with myeloid malignancies because genes essential for myelopoiesis are often mutated in human leukemias. We identified 4 nonsynonymous sequence variants (NSVs) of DDX18 in acute myeloid leukemia (AML) patient samples. RNA encoding wild-type DDX18 and 3 NSVs rescued the hematopoietic defect, indicating normal DDX18 activity. RNA encoding one mutation, DDX18-E76del, was unable to rescue hematopoiesis, and resulted in reduced myeloid cell numbers in ddx18(hi1727/+) embryos, indicating this NSV likely functions as a dominant- negative allele. These studies demonstrate the use of the zebrafish as a robust in vivo system for assessing the function of genes mutated in AML, which will become increasingly important as more sequence variants are identified by next-generation resequencing technologies.

AB Defining the T helper functions impaired by programmed death-1 (PD-1) is crucial for understanding its role in defective HIV control and determining the therapeutic potential of targeting this inhibitory pathway. We describe here the relationships among disease stage, levels of PD-1 expression, and reversibility of CD4 T-cell impairment. PD-L1 blockade in vitro enhanced HIV-specific production of Th0 (IL-2), Th1 (IFN-gamma), Th2 (IL-13), and TFH (IL-21) cytokines by CD4 T cells. PD-L1 blockade caused an early increase in cytokine transcription and translation that preceded cell proliferation. Although the impact of PD-L1 blockade on cytokine expression and, to a lesser extent, cell proliferation was associated with markers of disease progression, restoration of cytokine secretion was also observed in most subjects with undetectable viremia. PD-L1 blockade restored cytokine secretion in both PD-1intermediate and PD1high sorted CD4 T-cell subsets. Com-pared with PD-1high HIV-specific CD8 T cells, PD-1high HIV-specific CD4 T cells showed lower expression of the inhibitory molecules CD160 and 2B4, demonstrating marked differences in expression of inhibitory receptors between T-cell subsets. These data show that PD-1 impairs HIV-specific T helper responses both by limiting expansion of these cells and by inhibiting effector functions of multiple differentiated CD4 T-cell subsets.

AB Introduction: Gene expression patterns characterizing clinically-relevant molecular subgroups of glioblastoma are difficult to reproduce. We suspect a combination of biological and analytic factors confounds interpretation of glioblastoma expression data. We seek to clarify the nature and relative contributions of these factors, to focus additional investigations, and to improve the accuracy and consistency of translational glioblastoma analyses.
Methods: We analyzed gene expression and clinical data for 340 glioblastomas in The Cancer Genome Atlas (TCGA). We developed a logic model to analyze potential sources of biological, technical, and analytic variability and used standard linear classifiers and linear dimensional reduction algorithms to investigate the nature and relative contributions of each factor.
Results: Commonly-described sources of classification error, including individual sample characteristics, batch effects, and analytic and technical noise make measurable but proportionally minor contributions to inconsistent molecular classification. Our analysis suggests that three, previously underappreciated factors may account for a larger fraction of classification errors: inherent non-linear/non-orthogonal relationships among the genes used in conjunction with classification algorithms that assume linearity; skewed data distributions assumed to be Gaussian; and biologic variability (noise) among tumors, of which we propose three types.
Conclusions: Our analysis of the TCGA data demonstrates a contributory role for technical factors in molecular classification inconsistencies in glioblastoma but also suggests that biological variability, abnormal data distribution, and non-linear relationships among genes may be responsible for a proportionally larger component of classification error. These findings may have important implications for both glioblastoma research and for translational application of other large-volume biological databases.

AB Metastatic melanoma is a leading cause of death from skin diseases, and is often associated with activation of Wnt/beta-catenin signaling pathway. We have examined the inhibitory effect of silymarin, a plant flavanoid from Silybum marianum, on cell migration of metastasis-specific human melanoma cell lines (A375 and Hs294t) and assessed whether Wnt/beta-catenin signaling is the target of silymarin. Using an in vitro invasion assay, we found that treatment of human melanoma cell lines with silymarin resulted in concentration-dependent inhibition of cell migration, which was associated with accumulation of cytosolic beta-catenin, while reducing the nuclear accumulation of beta-catenin (i.e., b-catenin inactivation) and reducing the levels of matrix metalloproteinase (MMP)-2 and MMP-9 which are the down-stream targets of beta-catenin. Silymarin enhanced: (i) the levels of casein kinase 1 alpha, glycogen synthase kinase-3 beta and phosphorylated-beta-catenin on critical residues Ser(45), Ser(33/37) and Thr(41), and (ii) the binding of beta-transducin repeat-containing proteins (beta-TrCP) with phospho forms of beta-catenin in melanoma cells. These events play important roles in degradation or inactivation of beta-catenin. To verify whether beta-catenin is a potent molecular target of silymarin, the effect of silymarin was determined on beta-catenin-activated (Mel 1241) and beta-catenin-inactivated (Mel 1011) melanoma cells. Treatment of Mel 1241 cells with silymarin or FH535, an inhibitor of Wnt/beta-catenin pathway, significantly inhibited cell migration of Mel 1241 cells, which was associated with the elevated levels of casein kinase 1 alpha and glycogen synthase kinase-3 beta, and decreased accumulation of nuclear beta-catenin and inhibition of MMP-2 and MMP-9 levels. However, this effect of silymarin and FH535 was not found in Mel 1011 melanoma cells. These results indicate for the first time that silymarin inhibits melanoma cell migration by targeting beta-catenin signaling pathway.

TI LRAD3, A Novel Low-Density Lipoprotein Receptor Family Member That

AB We have identified a novel low-density lipoprotein (LDL) receptor family member, termed LDL receptor class A domain containing 3 (LRAD3), which is expressed in neurons. The LRAD3 gene encodes an similar to 50 kDa type I transmembrane receptor with an ectodomain containing three LDLa repeats, a transmembrane domain, and a cytoplasmic domain containing a conserved dileucine internalization motif and two polyproline motifs with potential to interact with WW-domain-containing proteins. Immunohistochemical analysis of mouse brain reveals LRAD3 expression in the cortex and hippocampus. In the mouse hippocampal-derived cell line HT22, LRAD3 partially colocalizes with amyloid precursor protein (APP) and interacts with APP as revealed by coimmunoprecipitation experiments. To identify the portion of APP that interacts with LRAD3, we used solid-phase binding assays that demonstrated that LRAD3 failed to bind to a soluble APP fragment (sAPP alpha) released after alpha-secretase cleavage. In contrast, C99, the beta-secretase product that remains cell associated, coprecipitated with LRAD3, confirming that regions within this portion of APP are important for associating with LRAD3. The association of LRAD3 with APP increases the amyloidogenic pathway of APP processing, resulting in a decrease in sAPP alpha production and increased A beta peptide production. Pulse-chase experiments confirm that LRAD3 expression significantly decreases the cellular half-life of mature APP. These results reveal that LRAD3 influences APP processing and raises the possibility that LRAD3 alters APP function in neurons, including its downstream signaling.

AB Aberrant histone deacetylase (HDAC) activity is frequent in human leukemias. However, while classical, NAD(+)-independent HDACs are an established therapeutic target, the relevance of NAD(+)-dependent HDACs (sirtuins) in leukemia treatment remains unclear. Here, we assessed the antileukemic activity of sirtuin inhibitors and of the NAD(+)-lowering drug FK866, alone and in combination with traditional HDAC inhibitors. Primary leukemia cells, leukemia cell lines, healthy leukocytes and hematopoietic progenitors were treated with sirtuin inhibitors (sirtinol, cambinol, EX527) and with FK866, with or without addition of the HDAC inhibitors valproic acid, sodium butyrate, and vorinostat. Cell death was quantified by propidium iodide cell staining and subsequent flow-cytometry. Apoptosis induction wasmonitored by cell staining with FITC-Annexin-V/propidium iodide or with TMRE followed by flow-cytometric analysis, and by measuring caspase3/7 activity. Intracellular Bax was detected by flow-cytometry and western blotting. Cellular NAD(+) levels were measured by enzymatic cycling assays. Bax was overexpressed by retroviral transduction. Bax and SIRT1 were silenced by RNA-interference. Sirtuin inhibitors and FK866 synergistically enhanced HDAC inhibitor activity in leukemia cells, but not in healthy leukocytes and hematopoietic progenitors. In leukemia cells, HDAC inhibitors were found to induce upregulation of Bax, a pro-apoptotic Bcl2 family-member whose translocation to mitochondria is normally prevented by SIRT1. As a result, leukemia cells become sensitized to sirtuin inhibitor-induced apoptosis. In conclusion, NAD(+)-independent HDACs and sirtuins cooperate in leukemia cells to avoid apoptosis. Combining sirtuin with HDAC inhibitors results in synergistic antileukemic activity that could be therapeutically exploited.

TI Retention in Care and Connection to Care among HIV-Infected Patients on
Antiretroviral Therapy in Africa: Estimation via a Sampling-Based
Approach
SO PLOS ONE
LA English
DT Article
ID COMPETING RISKS; PATIENTS LOST; RURAL UGANDA; FOLLOW-UP; PROGRAMS;
MORTALITY; OUTCOMES
AB Introduction: Current estimates of retention among HIV-infected patients on antiretroviral therapy (ART) in Africa consider patients who are lost to follow-up (LTF) as well as those who die shortly after their last clinic visit to be no longer in care and to represent limitations in access to care. Yet many lost patients may have "silently" transferred and deaths shortly after the last clinic visit more likely represent limitations in clinical care rather than access to care after initial linkage.
Methods: We evaluated HIV-infected adults initiating ART from 1/1/2004 to 9/30/2007 at a clinic in rural Uganda. A representative sample of lost patients was tracked in the community to obtain updated information about care at other ART sites. Updated outcomes were incorporated with probability weights to obtain "corrected" estimates of retention for the entire clinic population. We used the competing risks approach to estimate "connection to care"-the percentage of patients accessing care over time (including those who died while in care).
Results: Among 3,628 patients, 829 became lost, 128 were tracked and in 111, updated information was obtained. Of 111, 79 (71%) were alive and 35/48 (73%) of patients interviewed in person were in care and on ART. Patient retention for the clinic population assuming lost patients were not in care was 82.3%, 68.9%, and 60.1% at 1, 2 and 3 years. Incorporating updated care information from the sample of lost patients increased estimates of patient retention to 85.8% to 90.9%, 78.9% to 86.2% and 75.8% to 84.7% at the same time points.
Conclusions: Accounting for "silent transfers" and early deaths increased estimates of patient retention and connection to care substantially. Deaths soon after the last clinic visit (potentially reflecting limitations in clinical effectiveness) and disconnection from care among patient who were alive each accounted for approximately half of failures of retention.

AB Aims: TCF7L2 variants have been associated with type 2 diabetes, body mass index (BMI), and deficits in proinsulin processing and insulin secretion. Here we sought to test whether these effects were apparent in high-risk individuals and modify treatment responses.
Methods: We examined the potential role of the TCF7L2 rs7903146 variant in predicting resistance to weight loss or a lack of improvement of proinsulin processing during 2.5-years of follow-up participants (N = 2,994) from the Diabetes Prevention Program (DPP), a randomized controlled trial designed to prevent or delay diabetes in high-risk adults.
Results: We observed no difference in the degree of weight loss by rs7903146 genotypes. However, the T allele (conferring higher risk of diabetes) at rs7903146 was associated with higher fasting proinsulin at baseline (P, 0.001), higher baseline proinsulin: insulin ratio (p<0.0001) and increased proinsulin: insulin ratio over a median of 2.5 years of follow-up (P = 0.003). Effects were comparable across treatment arms.
Conclusions: The combination of a lack of impact of the TCF7L2 genotypes on the ability to lose weight, but the presence of a consistent effect on the proinsulin: insulin ratio over the course of DPP, suggests that high-risk genotype carriers at this locus can successfully lose weight to counter diabetes risk despite persistent deficits in insulin production.

AB Increased meiotic spindle abnormalities and aneuploidy in oocytes of women of advanced maternal ages lead to elevated rates of infertility, miscarriage, and trisomic conceptions. Despite the significance of the problem, strategies to sustain oocyte quality with age have remained elusive. Here we report that adult female mice maintained under 40% caloric restriction (CR) did not exhibit aging-related increases in oocyte aneuploidy, chromosomal misalignment on the metaphase plate, meiotic spindle abnormalities, or mitochondrial dysfunction (aggregation, impaired ATP production), all of which occurred in oocytes of age-matched ad libitum-fed controls. The effects of CR on oocyte quality in aging females were reproduced by deletion of the metabolic regulator, peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1 alpha). Thus, CR during adulthood or loss of PGC-1 alpha function maintains female germline chromosomal stability and its proper segregation during meiosis, such that ovulated oocytes of aged female mice previously maintained on CR or lacking PGC-1 alpha are comparable to those of young females during prime reproductive life.

AB A comprehensive understanding of the molecular vulnerabilities of every type of cancer will provide a powerful roadmap to guide therapeutic approaches. Efforts such as The Cancer Genome Atlas Project will identify genes with aberrant copy number, sequence, or expression in various cancer types, providing a survey of the genes that may have a causal role in cancer. A complementary approach is to perform systematic loss-of-function studies to identify essential genes in particular cancer cell types. We have begun a systematic effort, termed Project Achilles, aimed at identifying genetic vulnerabilities across large numbers of cancer cell lines. Here, we report the assessment of the essentiality of 11,194 genes in 102 human cancer cell lines. We show that the integration of these functional data with information derived from surveying cancer genomes pinpoints known and previously undescribed lineage-specific dependencies across a wide spectrum of cancers. In particular, we found 54 genes that are specifically essential for the proliferation and viability of ovarian cancer cells and also amplified in primary tumors or differentially over-expressed in ovarian cancer cell lines. One such gene, PAX8, is focally amplified in 16% of high-grade serous ovarian cancers and expressed at higher levels in ovarian tumors. Suppression of PAX8 selectively induces apoptotic cell death of ovarian cancer cells. These results identify PAX8 as an ovarian lineage-specific dependency. More generally, these observations demonstrate that the integration of genome-scale functional and structural studies provides an efficient path to identify dependencies of specific cancer types on particular genes and pathways.

DT Article
ID PHYSICAL-ACTIVITY QUESTIONNAIRES; ALZHEIMERS-DISEASE; EXERCISE;
DEMENTIA; DECLINE; HEALTH; RISK; WOMEN; VARIABILITY; POPULATION
AB Background: Studies suggest that physically active people have reduced risk of incident cognitive impairment in late life. However, these studies are limited by reliance on self-reports of physical activity, which only moderately correlate with objective measures and often exclude activity not readily quantifiable by frequency and duration. The objective of this study was to investigate the relationship between activity energy expenditure (AEE), an objective measure of total activity, and incidence of cognitive impairment.
Methods: We calculated AEE as 90% of total energy expenditure (assessed during 2 weeks using doubly labeled water) minus resting metabolic rate (measured using indirect calorimetry) in 197 men and women (mean age, 74.8 years) who were free of mobility and cognitive impairments at study baseline (1998-1999). Cognitive function was assessed at baseline and 2 or 5 years later using the Modified Mini-Mental State Examination. Cognitive impairment was defined as a decline of at least 1.0 SD (9 points) between baseline and follow-up evaluations.
Results: After adjustment for baseline Modified Mini-Mental State Examination scores, demographics, fatfree mass, sleep duration, self-reported health, and diabetes mellitus, older adults in the highest sex-specific tertile of AEE had lower odds of incident cognitive impairment than those in the lowest tertile (odds ratio, 0.09; 95% confidence interval, 0.01-0.79). There was also a significant dose response between AEE and incidence of cognitive impairment (P=.05 for trend over tertiles).
Conclusions: These findings indicate that greater AEE may be protective against cognitive impairment in a dose-response manner. The significance of overall activity in contrast to vigorous or light activity should be determined.

AB Background: Global activation of the embryonic genome (EGA), one of the most critical steps in early mammalian embryo development, is recognized as the time when interspecies somatic cell nuclear transfer (iSCNT) embryos fail to thrive.
Methodology/Principal Findings: In this study, we analyzed the EGA-related transcriptome of rhesus-bovine iSCNT 8-to 16-cell embryos and dissected the reprogramming process in terms of embryonic gene activation, somatic gene silencing, and maternal RNA degradation. Compared with fibroblast donor cells, two thousand and seven genes were activated in iSCNT embryos, one quarter of them reaching expression levels comparable to those found in in vitro fertilized (IVF) rhesus embryos. This suggested that EGA in iSCNT embryos had partially recapitulated rhesus embryonic development. Eight hundred and sixty somatic genes were not silenced properly and continued to be expressed in iSCNT embryos, which indicated incomplete nuclear reprogramming. We compared maternal RNA degradation in bovine oocytes between bovine-bovine SCNT and iSCNT embryos. While maternal RNA degradation occurred in both SCNT and iSCNT embryos, we saw more limited overall degradation of maternal RNA in iSCNT embryos than in SCNT embryos. Several important maternal RNAs, like GPF9, were not properly processed in SCNT embryos.
Conclusions/Significance: Our data suggested that iSCNT embryos are capable of triggering EGA, while a portion of somatic cell-associated genes maintain their expression. Maternal RNA degradation seems to be impaired in iSCNT embryos. Further understanding of the biological roles of these genes, networks, and pathways revealed by iSCNT may expand our knowledge about cell reprogramming, pluripotency, and differentiation.

AB Background Glutamic acid decarboxylase (GAD) is a major target of the autoimmune response that occurs in type 1 diabetes mellitus. In animal models of autoimmunity, treatment with a target antigen can modulate aggressive autoimmunity. We aimed to assess whether immunisation with GAD formulated with aluminum hydroxide (GAD-alum) would preserve insulin production in recent-onset type 1 diabetes.
Methods Patients aged 3-45 years who had been diagnosed with type 1 diabetes for less than 100 days were enrolled from 15 sites in the USA and Canada, and randomly assigned to receive one of three treatments: three injections of 20 mu g GAD-alum, two injections of 20 mu g GAD-alum and one of alum, or 3 injections of alum. Injections were given subcutaneously at baseline, 4 weeks later, and 8 weeks after the second injection. The randomisation sequence was computer generated at the TrialNet coordinating centre. Patients and study personnel were masked to treatment assignment. The primary outcome was the baseline-adjusted geometric mean area under the curve (AUC) of serum C-peptide during the first 2 h of a 4-h mixed meal tolerance test at 1 year. Secondary outcomes included changes in glycated haemoglobin A(1c) (HbA(1c)) and insulin dose, and safety. Analysis included all randomised patients with known measurements. This trial is registered with ClinicalTrials.gov, number NCT00529399.
Findings 145 patients were enrolled and treated with GAD-alum (n=48), GAD-alum plus alum (n=49), or alum (n=48). At 1 year, the 2-h AUC of C-peptide, adjusted for age, sex, and baseline C-peptide value, was 0.412 nmol/L (95% CI 0.349-0.478) in the GAD-alum group, 0.382 nmol/L (0.322-0.446) in the GAD-alum plus alum group, and 0.413 nmol/L (0.351-0.477) in the alum group. The ratio of the population mean of the adjusted geometric mean 2-h AUC of C-peptide was 0.998 (95% CI 0.779-1.22; p=0.98) for GAD-alum versus alum, and 0.926 (0.720-1.13; p=0.50) for GAD-alum plus alum versus alum. HbA(1c), insulin use, and the occurrence and severity of adverse events did not differ between groups.
Interpretation Antigen-based immunotherapy therapy with two or three doses of subcutaneous GAD-alum across 4-12 weeks does not alter the course of loss of insulin secretion during 1 year in patients with recently diagnosed type 1 diabetes. Although antigen-based therapy is a highly desirable treatment and is effective in animal models, translation to human autoimmune disease remains a challenge.

AB Background: There is widespread interest in measuring organizational readiness to implement evidence-based practices in clinical care. However, there are a number of challenges to validating organizational measures, including inferential bias arising from the halo effect and method bias - two threats to validity that, while well-documented by organizational scholars, are often ignored in health services research. We describe a protocol to comprehensively assess the psychometric properties of a previously developed survey, the Organizational Readiness to Change Assessment.
Objectives: Our objective is to conduct a comprehensive assessment of the psychometric properties of the Organizational Readiness to Change Assessment incorporating methods specifically to address threats from halo effect and method bias.
Methods and Design: We will conduct three sets of analyses using longitudinal, secondary data from four partner projects, each testing interventions to improve the implementation of an evidence-based clinical practice. Partner projects field the Organizational Readiness to Change Assessment at baseline (n = 208 respondents; 53 facilities), and prospectively assesses the degree to which the evidence-based practice is implemented. We will conduct predictive and concurrent validities using hierarchical linear modeling and multivariate regression, respectively. For predictive validity, the outcome is the change from baseline to follow-up in the use of the evidence-based practice. We will use intra-class correlations derived from hierarchical linear models to assess inter-rater reliability. Two partner projects will also field measures of job satisfaction for convergent and discriminant validity analyses, and will field Organizational Readiness to Change Assessment measures at follow-up for concurrent validity (n = 158 respondents; 33 facilities). Convergent and discriminant validities will test associations between organizational readiness and different aspects of job satisfaction: satisfaction with leadership, which should be highly correlated with readiness, versus satisfaction with salary, which should be less correlated with readiness. Content validity will be assessed using an expert panel and modified Delphi technique.
Discussion: We propose a comprehensive protocol for validating a survey instrument for assessing organizational readiness to change that specifically addresses key threats of bias related to halo effect, method bias and questions of construct validity that often go unexplored in research using measures of organizational constructs.

AB Hyperglycemia induces a wide array of signaling pathways in the kidney that lead to hypertrophy and matrix expansion, eventually culminating in progressive kidney failure. High glucose-induced reduction of the tumor suppressor protein phosphatase and tensin homolog deleted in chromosome 10 (PTEN) contributes to renal cell hypertrophy and matrix expansion. We identified microRNA-21 (miR-21) as the molecular link between high glucose and PTEN suppression. Renal cortices from OVE26 type 1 diabetic mice showed significantly elevated levels of miR-21 associated with reduced PTEN and increased fibronectin content. In renal mesangial cells, high glucose increased the expression of miR-21, which targeted the 3'-UTR of PTEN mRNA to inhibit PTEN protein expression. Overexpression of miR-21 mimicked the action of high glucose, which included a reduction in PTEN expression and a concomitant increase in Akt phosphorylation. In contrast, expression of miR-21 Sponge, to inhibit endogenous miR-21, prevented down-regulation of PTEN and phosphorylation of Akt induced by high glucose. Interestingly, high glucose-stimulated miR-21 inactivated PRAS40, a negative regulator of TORC1. Finally, miR-21 enhanced high glucose-induced TORC1 activity, resulting in renal cell hypertrophy and fibronectin expression. Thus, our results identify a previously unrecognized function of miR-21 that is the reciprocal regulation of PTEN levels and Akt/TORC1 activity that mediate critical pathologic features of diabetic kidney disease.

TI Epithelial Junctions Depend on Intercellular Trans-interactions between

AB N-Glycans of the Na,K-ATPase beta(1) subunit are important for intercellular adhesion in epithelia, suggesting that epithelial junctions depend on N-glycan-mediated interactions between the beta(1) subunits of neighboring cells. The level of co-immunoprecipitation of the endogenous beta(1) subunit with various YFP-linked beta(1) subunits expressed in Madin-Darby canine kidney cells was used to assess beta(1)-beta(1) interactions. The amount of co-precipitated endogenous dog beta(1) was greater with dog YFP-beta(1) than with rat YFP-beta(1), showing that amino acid-mediated interactions are important for beta(1)-beta(1) binding. Co-precipitation of beta(1) was also less with the unglycosylated YFP-beta(1) than with glycosylated YFP-beta(1), indicating a role for N-glycans. Mixing cells expressing dog YFP-beta(1) with non-transfected cells increased the amount of co-precipitated beta(1), confirming the presence of intercellular (YFP-beta(1))-beta(1) complexes. Accordingly, disruption of intercellular junctions decreased the amount of co-precipitated beta(1) subunits. The decrease in beta(1) co-precipitation both with rat YFP-beta(1) and unglycosylated YFP-beta(1) was associated with decreased detergent stability of junctional proteins and increased paracellular permeability. Reducing N-glycan branching by specific inhibitors increased (YFP-beta(1))-beta(1) co-precipitation and strengthened intercellular junctions. Therefore, interactions between the beta(1) subunits of neighboring cells maintain integrity of intercellular junctions, and alterations in the beta(1) subunit N-glycan structure can regulate stability and tightness of intercellular junctions.

TI Novel Automated Blood Separations Validate Whole Cell Biomarkers
SO PLOS ONE
LA English
DT Article
ID PERIPHERAL-BLOOD; T-CELLS; LYMPHOCYTES; INHIBITORS
AB Background: Progress in clinical trials in infectious disease, autoimmunity, and cancer is stymied by a dearth of successful whole cell biomarkers for peripheral blood lymphocytes (PBLs). Successful biomarkers could help to track drug effects at early time points in clinical trials to prevent costly trial failures late in development. One major obstacle is the inaccuracy of Ficoll density centrifugation, the decades-old method of separating PBLs from the abundant red blood cells (RBCs) of fresh blood samples.
Methods and Findings: To replace the Ficoll method, we developed and studied a novel blood-based magnetic separation method. The magnetic method strikingly surpassed Ficoll in viability, purity and yield of PBLs. To reduce labor, we developed an automated platform and compared two magnet configurations for cell separations. These more accurate and labor-saving magnet configurations allowed the lymphocytes to be tested in bioassays for rare antigen-specific T cells. The automated method succeeded at identifying 79% of patients with the rare PBLs of interest as compared with Ficoll's uniform failure. We validated improved upfront blood processing and show accurate detection of rare antigen-specific lymphocytes.
Conclusions: Improving, automating and standardizing lymphocyte detections from whole blood may facilitate development of new cell-based biomarkers for human diseases. Improved upfront blood processes may lead to broad improvements in monitoring early trial outcome measurements in human clinical trials.

TI Barx1-Mediated Inhibition of Wnt Signaling in the Mouse Thoracic Foregut

AB Mesenchymal cells underlying the definitive endoderm in vertebrate animals play a vital role in digestive and respiratory organogenesis. Although several signaling pathways are implicated in foregut patterning and morphogenesis, and despite the clinical importance of congenital tracheal and esophageal malformations in humans, understanding of molecular mechanisms that allow a single tube to separate correctly into the trachea and esophagus is incomplete. The homoebox gene Barx1 is highly expressed in prospective stomach mesenchyme and required to specify this organ. We observed lower Barx1 expression extending contiguously from the proximal stomach domain, along the dorsal anterior foregut mesenchyme and in mesenchymal cells between the nascent esophagus and trachea. This expression pattern exactly mirrors the decline in Wnt signaling activity in late development of the adjacent dorsal foregut endoderm and medial mainstem bronchi. The hypopharynx in Barx1(-/-) mouse embryos is abnormally elongated and the point of esophagotracheal separation shows marked caudal displacement, resulting in a common foregut tube that is similar to human congenital tracheo-esophageal fistula and explains neonatal lethality. Moreover, the Barx1(-/-) esophagus displays molecular and cytologic features of respiratory endoderm, phenocopying abnormalities observed in mouse embryos with activated beta-catenin. The zone of canonical Wnt signaling is abnormally prolonged and expanded in the proximal Barx1(-/-) foregut. Thus, as in the developing stomach, but distinct from the spleen, Barx1 control of thoracic foregut specification and tracheo-esophageal septation is tightly associated with down-regulation of adjacent Wnt pathway activity.

AB The ataxia telangiectasia-mutated and Rad3-related (ATR) kinase is a master checkpoint regulator safeguarding the genome. Upon DNA damage, the ATR-ATRIP complex is recruited to sites of DNA damage by RPA-coated single-stranded DNA and activated by an elusive process. Here, we show that ATR is transformed into a hyperphosphorylated state after DNA damage, and that a single autophosphorylation event at Thr 1989 is crucial for ATR activation. Phosphorylation of Thr 1989 relies on RPA, ATRIP, and ATR kinase activity, but unexpectedly not on the ATR stimulator TopBP1. Recruitment of ATR-ATRIP to RPA-ssDNA leads to congregation of ATR-ATRIP complexes and promotes Thr 1989 phosphorylation in trans. Phosphorylated Thr 1989 is directly recognized by TopBP1 via the BRCT domains 7 and 8, enabling TopBP1 to engage ATR-ATRIP, to stimulate the ATR kinase, and to facilitate ATR substrate recognition. Thus, ATR autophosphorylation on RPA-ssDNA is a molecular switch to launch robust checkpoint response.

AB Patient-specific induced pluripotent stem cells (iPSCs) derived from somatic cells provide a unique tool for the study of human disease, as well as a promising source for cell replacement therapies. One crucial limitation has been the inability to perform experiments under genetically defined conditions. This is particularly relevant for late age onset disorders in which in vitro phenotypes are predicted to be subtle and susceptible to significant effects of genetic background variations. By combining zinc finger nuclease (ZFN)-mediated genome editing and iPSC technology, we provide a generally applicable solution to this problem, generating sets of isogenic disease and control human pluripotent stem cells that differ exclusively at either of two susceptibility variants for Parkinson's disease by modifying the underlying point mutations in the a-synuclein gene. The robust capability to genetically correct disease-causing point mutations in patient-derived hiPSCs represents significant progress for basic biomedical research and an advance toward hiPSC-based cell replacement therapies.

AB This phase 1/2 trial evaluated combination lenalidomide, bortezomib, pegylated liposomal doxorubicin, and dexamethasone (RVDD) in newly diagnosed multiple myeloma (MM) patients. Patients received RVDD at 4 dose levels, including the maximum tolerated dose (MTD). Patients with a very good partial response or better (>= VGPR) after cycle 4 proceeded to autologous stem cell transplantation or continued treatment. The primary objectives were MTD evaluation and response to RVDD after 4 and 8 cycles. Seventy-two The MTDs were lenalidomide 25 mg, bortezomib 1.3 mg/m(2), pegylated liposomal doxorubicin 30 mg/m(2), and dexamethasone 20/10 mg, as established with 3-week cycles. The most common adverse events were fatigue, constipation, sensory neuropathy, and infection; there was no treatment-related mortality. Response rates after 4 and 8 cycles were 96% and 95% partial response or better, 57% and 65% >= VGPR, and 29% and 35% complete or near-complete response, respectively. After a median follow-up of 15.5 months, median progression-free survival (PFS) and overall survival (OS) were not reached. The estimated 18-month PFS and OS were 80.8% and 98.6%, respectively. RVDD was generally well tolerated and highly active, warranting further study in newly diagnosed MM patients. This trial was registered at www.clinicaltrials.gov as NCT00724568.

TI Regulation of TMPRSS6 by BMP6 and iron in human cells and mice

AB Mutations in transmembrane protease, serine 6 (TMPRSS6), encoding matriptase-2, are responsible for the familial anemia disorder iron-refractory iron deficiency anemia (IRIDA). Patients with IRIDA have inappropriately elevated levels of the iron regulatory hormone hepcidin, suggesting that TMPRSS6 is involved in negatively regulating hepcidin expression. Hepcidin is positively regulated by iron via the bone morphogenetic protein (BMP)-SMAD signaling pathway. In this study, we investigated whether BMP6 and iron also regulate TMPRSS6 expression. Here we demonstrate that, in vitro, treatment with BMP6 stimulates TMPRSS6 expression at the mRNA and protein levels and leads to an increase in matriptase-2 activity. Moreover, we identify that inhibitor of DNA binding 1 is the key element of the BMP-SMAD pathway to regulate TMPRSS6 expression in response to BMP6 treatment. Finally, we show that, in mice, Tmprss6 mRNA expression is stimulated by chronic iron treatment or BMP6 injection and is blocked by injection of neutralizing antibody against BMP6. Our results indicate that BMP6 and iron not only induce hepcidin expression but also induce TMPRSS6, a negative regulator of hepcidin expression. Modulation of TMPRSS6 expression could serve as a negative feedback inhibitor to avoid excessive hepcidin increases by iron to help maintain tight homeostatic balance of systemic iron levels.

AB Background: Despite over forty years of investigation on low-level light therapy (LLLT), the fundamental mechanisms underlying photobiomodulation at a cellular level remain unclear.
Methodology/Principal Findings: In this study, we isolated murine embryonic fibroblasts (MEF) from transgenic NF-kB luciferase reporter mice and studied their response to 810 nm laser radiation. Significant activation of NF-kB was observed at fluences higher than 0.003 J/cm(2) and was confirmed by Western blot analysis. NF-kB was activated earlier (1 hour) by LLLT compared to conventional lipopolysaccharide treatment. We also observed that LLLT induced intracellular reactive oxygen species (ROS) production similar to mitochondrial inhibitors, such as antimycin A, rotenone and paraquat. Furthermore, we observed similar NF-kB activation with these mitochondrial inhibitors. These results, together with inhibition of laser induced NF-kB activation by antioxidants, suggests that ROS play an important role in the laser induced NF-kB signaling pathways. However, LLLT, unlike mitochondrial inhibitors, induced increased cellular ATP levels, which indicates that LLLT also upregulates mitochondrial respiration.
Conclusion: We conclude that LLLT not only enhances mitochondrial respiration, but also activates the redox-sensitive NFkB signaling via generation of ROS. Expression of anti-apoptosis and pro-survival genes responsive to NFkB could explain many clinical effects of LLLT.

AB Computed tomography images have been acquired using an experimental (low atomic number (Z) insert) megavoltage cone-beam imaging system. These images have been compared with standard megavoltage and kilovoltage imaging systems. The experimental system requires a simple modification to the 4 MeV electron beam from an Elekta Precise linac. Low-energy photons are produced in the standard medium-Z electron window and a low-Z carbon electron absorber located after the window. The carbon electron absorber produces photons as well as ensuring that all remaining electrons from the source are removed. A detector sensitive to diagnostic x-ray energies is also employed. Quantitative assessment of cone-beam computed tomography (CBCT) contrast shows that the low-Z imaging system is an order of magnitude or more superior to a standard 6 MV imaging system. CBCT data with the same contrast-to-noise ratio as a kilovoltage imaging system (0.15 cGy) can be obtained in doses of 11 and 244 cGy for the experimental and standard 6 MV systems, respectively. Whilst these doses are high for everyday imaging, qualitative images indicate that kilovoltage like images suitable for patient positioning can be acquired in radiation doses of 1-8 cGy with the experimental low-Z system.

AB A safe, efficacious vaccine is required to stop the AIDS pandemic. Disappointing results from the STEP trial implied a need to include humoral anti-HIV-1 responses, a notion supported by RV144 trial data even though correlates of protection are unknown. We vaccinated rhesus macaques with recombinant simian immunodeficiency virus (SIV) Gag-Pol particles, HIV-1 Tat and trimeric clade C (HIV-C) gp160, which induced cross-neutralizing antibodies (nAbs) and robust cellular immune responses. After five low-dose mucosal challenges with a simian-human immunodeficiency virus (SHIV) that encoded a heterologous R5 HIV-C envelope (22.1% divergence from the gp160 immunogen), 94% of controls became viremic, whereas one third of vaccinees remained virus-free. Upon high-dose SHIV rechallenge, all controls became infected, whereas some vaccinees remained aviremic. Peak viremia was inversely correlated with both cellular immunity (p<0.001) and cross-nAb titers (p<0.001). These data simultaneously linked cellular as well as humoral immune responses with the degree of protection for the first time.

AB Originally identified as an angiogenic factor, vascular endothelial growth factor (VEGF-A) is now known to play multiple roles in the CNS, including the direct regulation of neuronal and astrocytic functions. Here, we ask whether VEGF-A can also have a novel role in white matter by modulating oligodendrocyte precursor cells (OPCs). OPCs were cultured from rat neonatal cortex. Expression of VEGF-receptor2/KDR/Flk-1 was confirmed with Western blot and immunostaining. VEGF-A did not affect proliferation or differentiation in OPC cultures, but VEGF-A promoted OPC migration in a concentration-dependent manner. Consistent with this migration phenotype, VEGF-A-treated OPCs showed reorganization of actin cytoskeleton in leading-edge processes. VEGF-A-induced migration and actin reorganization were inhibited by an anti-Flk-1 receptor-blocking antibody. Mechanistically, VEGF-A induced binding of focal adhesion kinase (FAK) with paxillin. The FAK inhibitor PF573228 reduced VEGF-A-induced OPC migration. VEGF-A signaling also evoked a transient rise in reactive oxygen species (ROS), and OPC migration was increased when antioxidants were removed from the culture media. Our findings demonstrate that VEGF-A can induce OPC migration via an ROS- and FAK-dependent mechanism, and suggest a novel role for VEGF-A in white-matter maintenance and homeostasis.

AB Purpose
Melanomas harbor aberrations in the c-Kit gene. We tested the efficiency of the tyrosine kinase inhibitor imatinib in selected patients with metastatic melanoma harboring c-Kit mutations or amplifications.
Patients and Methods
Forty-three patients with metastatic melanoma harboring c-Kit aberrations were enrolled on this phase II trial. Each patient received a continuous dose of imatinib 400 mg/d unless intolerable toxicities or disease progression occurred. Fifteen patients who experienced progression of disease were allowed to escalate the dose to 800 mg/d.
Results
Forty-three patients were eligible for evaluation, and the median follow-up time was 12.0 months. The median progression-free survival (PFS) was 3.5 months, and the 6-month PFS rate was 36.6%. Rate of total disease control was 53.5%: 10 patients (23.3%; 95% CI, 10.2% to 36.4%) and 13 patients (30.2%; 95% CI, 16.0% to 44.4%) achieved partial response (PR) and stable disease (SD), respectively. Eighteen patients (41.9%) demonstrated regression of tumor mass. Notably, nine of the 10 PRs were observed in patients with mutations in exons 11 or 13. The 1-year overall survival (OS) rate was 51.0%. The median PFS and OS times for patients who had PR or SD versus disease progression were 9.0 months versus 1.5 months (P < .001) and 15.0 months versus 9.0 months (P = .036), respectively. Imatinib 400 mg/d was well tolerated, and only one of the 15 patients who received dose escalation to 800 mg/d achieved SD.
Conclusion
Imatinib demonstrated significant activity in patients with metastatic melanoma harboring genetic c-Kit aberrations, with an overall response rate of 23.3%. Escalation to 800 mg/d could not restore disease control. J Clin Oncol 29:2904-2909. (C) 2011 by American Society of Clinical Oncology

AB Background: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease that affects spinal cord and cortical motor neurons. An increasing amount of evidence suggests that mitochondrial dysfunction contributes to motor neuron death in ALS. Peroxisome proliferator-activated receptor gamma co-activator-1 alpha (PGC-1 alpha) is a principal regulator of mitochondrial biogenesis and oxidative metabolism.
Results: In this study, we examined whether PGC-1 alpha plays a protective role in ALS by using a double transgenic mouse model where PGC-1 alpha is over-expressed in an SOD1 transgenic mouse (TgSOD1-G93A/PGC-1 alpha). Our results indicate that PGC-1 alpha significantly improves motor function and survival of SOD1-G93A mice. The behavioral improvements were accompanied by reduced blood glucose level and by protection of motor neuron loss, restoration of mitochondrial electron transport chain activities and inhibition of stress signaling in the spinal cord.
Conclusion: Our results demonstrate that PGC-1 alpha plays a beneficial role in a mouse model of ALS, suggesting that PGC-1 alpha may be a potential therapeutic target for ALS therapy.

AB High-risk cutaneous squamous cell carcinoma (SCC) is associated with an increased risk of metastases. The role of sentinel lymph node (SLN) biopsy in these patients remains unclear. To address this uncertainty, we collected clinical data on six patients with clinical N0 high-risk SCC that underwent SLN biopsy between 1999 and 2006 and performed a literature review of SLN procedures for SCC to study the utility of SLN biopsy. There were no positive SLN identified among six cases and there was one local and one distant recurrence on follow-up. Literature review identified 130 reported cases of SLN biopsy for SCC. The SLN positivity rate was 14.1%, 10.1%, and 18.6%; false negative rate was 15.4%, 0%, and 22.2%; and the negative predictive value was 97.8%, 100%, and 95.2% for all sites, head/neck, and truncal/extremity sites, respectively. SLN biopsy remains an investigational staging tool in clinically node-negative high-risk SCC patients. The higher false negative rate and lower negative predictive value among SCC of the trunk/extremity compared to SCC of the head/neck sites suggests a more cautious approach when treating patients with the former. Given the paucity of long-term follow up, an emphasis is placed upon the need for close surveillance regardless of SLN status.

AB Combinatorial libraries of artificial zinc-finger transcription factors (ZF-TFs) provide a robust tool for inducing and understanding various functional components of the cancer phenotype. Herein, we utilized combinatorial ZF-TF library technology to better understand how breast cancer cells acquire resistance to fulvestrant, a clinically important anti-endocrine therapeutic agent. From a diverse collection of nearly 400,000 different ZF-TFs, we isolated six ZF-TF library members capable of inducing stable, long-term anti-endocrine drug-resistance in two independent estrogen receptor-positive breast cancer cell lines. Comparative gene expression profile analysis of the six different ZF-TF-transduced breast cancer cell lines revealed five distinct clusters of differentially expressed genes. One cluster was shared among all 6 ZF-TF-transduced cell lines and therefore constituted a common fulvestrant-resistant gene expression signature. Pathway enrichment-analysis of this common fulvestrant resistant signature also revealed significant overlap with gene sets associated with an estrogen receptor-negative-like state and with gene sets associated with drug resistance to different classes of breast cancer anti-endocrine therapeutic agents. Enrichment-analysis of the four remaining unique gene clusters revealed overlap with myb-regulated genes. Finally, we also demonstrated that the common fulvestrant-resistant signature is associated with poor prognosis by interrogating five independent, publicly available human breast cancer gene expression datasets. Our results demonstrate that artificial ZF-TF libraries can be used successfully to induce stable drug-resistance in human cancer cell lines and to identify a gene expression signature that is associated with a clinically relevant drug-resistance phenotype.

AB Background: Little is known about the possible differences in outcomes between patients with chronic obstructive pulmonary disease (COPD) who live in rural areas and those who live in urban areas of the United States.
Objective: To determine whether COPD-related mortality is higher in persons living in rural areas, and to assess whether hospital characteristics influence any observed associations.
Design: Retrospective cohort study.
Setting: 129 acute care Veterans Affairs hospitals.
Patients: Hospitalized patients with a COPD exacerbation.
Measurements: Patient rurality (primary exposure); 30-day mortality (primary outcome); and hospital volume and hospital rurality, defined as the mean proportion of hospital admissions coming from rural areas (secondary exposures).
Results: 18 809 patients (71% of the study population) lived in urban areas, 5671 (21%) in rural areas, and 1919 (7%) in isolated rural areas. Mortality was increased in patients living in isolated rural areas compared with urban areas (5.0% vs. 3.8%; P = 0.002). The increase in mortality associated with living in an isolated rural area persisted after adjustment for patient characteristics and hospital rurality and volume (odds ratio [OR], 1.42 [95% CI, 1.07 to 1.89]; P = 0.016). Adjusted mortality did not seem to be higher in patients living in nonisolated rural areas (OR, 1.09 [CI, 0.90 to 1.32]; P = 0.47). Results were unchanged in analyses assessing the influence of an omitted confounder on estimates.
Limitations: The study population was limited to mostly male inpatients who were veterans. Results were based on administrative data.
Conclusion: Patients with COPD living in isolated rural areas of the United States seem to be at greater risk for COPD exacerbation-related mortality than those living in urban areas, independent of hospital rurality and volume. Mortality was not increased for patients living in nonisolated rural areas.

TI Balancing Punishment and Compassion for Seriously III Prisoners
SO ANNALS OF INTERNAL MEDICINE
LA English
DT Editorial Material
ID PALLIATIVE CARE; LIFE; DISABILITY; END
AB Compassionate release is a program that allows some eligible, seriously ill prisoners to die outside of prison before sentence completion. It became a matter of federal statute in 1984 and has been adopted by most U. S. prison jurisdictions. Incarceration is justified on 4 principles: retribution, rehabilitation, deterrence, and incapacitation. Compassionate release derives from the theory that changes in health status may affect these principles and thus alter justification for incarceration and sentence completion. The medical profession is intricately involved in this process because eligibility for consideration for compassionate release is generally based on medical evidence. Many policy experts are calling for broader use of compassionate release because of many factors, such as an aging prison population, overcrowding, the increasing deaths in custody, and the soaring medical costs of the criminal justice system. Even so, the medical eligibility criteria of many compassionate-release guidelines-which often assume a definitive prognosis-are clinically flawed, and procedural barriers may further limit their rational application. We propose changes to address these flaws.

AB Objectives The purpose of this study was to develop a risk stratification score to predict warfarin-associated hemorrhage.
Background Optimal decision making regarding warfarin use for atrial fibrillation requires estimation of hemorrhage risk.
Methods We followed up 9,186 patients with atrial fibrillation contributing 32,888 person-years of follow-up on warfarin, obtaining data from clinical databases and validating hemorrhage events using medical record review. We used Cox regression models to develop a hemorrhage risk stratification score, selecting candidate variables using bootstrapping approaches. The final model was internally validated by split-sample testing and compared with 6 published hemorrhage risk schemes.
Results We observed 461 first major hemorrhages during follow-up (1.4% annually). Five independent variables were included in the final model and weighted by regression coefficients: anemia (3 points), severe renal disease (e. g., glomerular filtration rate <30 ml/min or dialysis-dependent, 3 points), age >= 75 years (2 points), prior bleeding (1 point), and hypertension (1 point). Major hemorrhage rates ranged from 0.4% (0 points) to 17.3% per year (10 points). Collapsed into a 3-category risk score, major hemorrhage rates were 0.8% for low risk (0 to 3 points), 2.6% for intermediate risk (4 points), and 5.8% for high risk (5 to 10 points). The c-index for the continuous risk score was 0.74 and 0.69 for the 3-category score, higher than in the other risk schemes. There was net reclassification improvement versus all 6 comparators (from 27% to 56%).
Conclusions A simple 5-variable risk score was effective in quantifying the risk of warfarin-associated hemorrhage in a large community-based cohort of patients with atrial fibrillation. (J Am Coll Cardiol 2011;58:395-401) (C) 2011 by the American College of Cardiology Foundation

AB Objectives The purpose of this study was to test whether the 9p21.3 variant rs1333040 influences the occurrence of new cardiovascular events and coronary atherosclerosis progression after early-onset myocardial infarction.
Background 9p21.3 genetic variants are associated with ischemic heart disease, but it is not known whether they influence prognosis after an acute coronary event.
Methods Within the Italian Genetic Study of Early-onset Myocardial Infarction, we genotyped rs1333040 in 1,508 patients hospitalized for a first myocardial infarction before the age of 45 years who underwent coronary angiography without index event coronary revascularization. They were followed up for major cardiovascular events and angiographic coronary atherosclerosis progression.
Results Over 16,599 person-years, there were 683 cardiovascular events and 492 primary endpoints: 77 cardiovascular deaths, 223 reoccurrences of myocardial infarction, and 383 coronary artery revascularizations. The rs1333040 genotype had a significant influence (p = 0.01) on the primary endpoint, with an adjusted hazard ratio of 1.19 (95% confidence interval [CI]: 1.08 to 1.37) for heterozygous carriers and 1.41 (95% CI: 1.06 to 1.87) for homozygous carriers. Analysis of the individual components of the primary endpoints provided no significant evidence that the rs1333040 genotype influenced the hazard of cardiovascular death (p = 0.24) or the reoccurrence of myocardial infarction (p = 0.57), but did provide significant evidence that it influenced on the hazard of coronary revascularization, with adjusted heterozygous and homozygous ratios of 1.38 (95% CI: 1.17 to 1.63) and 1.90 (95% CI: 1.36 to 2.65) (p = 0.00015), respectively. It also significantly influenced the angiographic endpoint of coronary atherosclerosis progression (p = 0.002).
Conclusions In early-onset myocardial infarction, the 9p21.3 variant rs1333040 affects the progression of coronary atherosclerosis and the probability of coronary artery revascularization during long-term follow-up.

AB "Humanized" mice offer a window into aspects of human physiology that are otherwise inaccessible. The best available methods for liver humanization rely on cell transplantation into immunodeficient mice with liver injury but these methods have not gained widespread use due to the duration and variability of hepatocyte repopulation. In light of the significant progress that has been achieved in clinical cell transplantation through tissue engineering, we sought to develop a humanized mouse model based on the facile and ectopic implantation of a tissue-engineered human liver. These human ectopic artificial livers (HEALs) stabilize the function of cryopreserved primary human hepatocytes through juxtacrine and paracrine signals in polymeric scaffolds. In contrast to current methods, HEALs can be efficiently established in immunocompetent mice with normal liver function. Mice transplanted with HEALs exhibit humanized liver functions persistent for weeks, including synthesis of human proteins, human drug metabolism, drug-drug interaction, and drug-induced liver injury. Here, mice with HEALs are used to predict the disproportionate metabolism and toxicity of "major" human metabolites using multiple routes of administration and monitoring. These advances may enable manufacturing of reproducible in vivo models for diverse drug development and research applications.

AB Evidence for cooperation between actin nucleators is growing. The WH2-containing nucleator Spire and the formin Cappuccino interact directly, and both are essential for assembly of an actin mesh during Drosophila oogenesis. Their interaction requires the kinase noncatalytic C-lobe domain (KIND) domain of Spire and the C-terminal tail of the formin. Here we describe the crystal structure of the KIND domain of human Spir1 alone and in complex with the tail of Fmn2, a mammalian ortholog of Cappuccino. The KIND domain is structurally similar to the C-lobe of protein kinases. The Fmn2 tail is coordinated in an acidic cleft at the base of the domain that appears to have evolved via deletion of a helix from the canonical kinase fold. Our functional analysis of Cappuccino reveals an unexpected requirement for its tail in actin assembly. In addition, we find that the KIND/tail interaction blocks nucleation by Cappuccino and promotes its displacement from filament barbed ends providing insight into possible modes of cooperation between Spire and Cappuccino.

AB Individual cell types are defined by architecturally and functionally specialized cortical domains. The Ezrin, Radixin, and Moesin (ERM) proteins play a major role in organizing cortical domains by assembling membrane protein complexes and linking them to the cortical actin cytoskeleton. Many studies have focused on the individual roles of the ERM proteins in stabilizing the membrane-cytoskeleton interface, controlling the distribution and function of apical membrane complexes, regulating the small GTPase Rho, or establishing cell-cell junctions. We previously found that deletion of the mouse Ezrin gene yields severe defects in apical integrity throughout the developing intestinal epithelium, resulting in incomplete villus morphogenesis and neonatal death. However, the molecular function of Ezrin in building the apical surface of the intestinal epithelium was not clear. By deleting Ezrin in the adult mouse intestinal epithelium, we provide evidence that Ezrin performs multiple molecular functions that collaborate to build the functional apical surface of the intestinal epithelium in vivo. The loss of Ezrin-mediated apical integrity in the adult intestine yields severe morphological consequences during intestinal homeostasis, including defects in cell geometry, extrusion, junctional remodeling, and spindle orientation. Surprisingly, deletion of Ezrin either before or after villus morphogenesis yields villus fusion, revealing a previously unrecognized step in intestinal homeostasis. Our studies indicate that the function of Ezrin in building and maintaining the apical domain is essential not only for intestinal morphogenesis but also for homeostasis in the mature intestine.

AB Early vaccination against influenza viruses is a cost-effective solution to prevent contagion and reduce influenza-related morbidity and mortality. In the face of pandemic viruses, such as the A(H1N1), adequate rates of vaccine uptake play a critical role in containing the spread and effects of the disease. In order to understand the reasons underlying the relatively low 2009-2010 A(H1N1) vaccination rates, we conducted an online survey of 1569 respondents drawn from a nationally representative sample of United States (U.S.) adults age 18, and older. Because prior research suggests that vaccination rates are especially low among some U.S. population subgroups, we oversampled participants from minority ethnic/racial groups and those living under the Federal Poverty Level. Our results show that A(H1N1) vaccine uptake is associated with sociodemographic factors, A(H1N1)-related beliefs and seasonal vaccination. That is, A(H1N1) vaccination is strongly associated with age, urbanicity, perceiving the A(H1N1) vaccine as safe and seasonal flu vaccine uptake. Perceptions of safety and season flu vaccination show the strongest associations with A(H1N1) uptake. The reasons people gave to decline vaccination varied by respondents' sociodemographic group. For example, Black participants were the most likely ethnic/racial group to reported having tried to get the vaccine but found it unavailable. Together, these findings suggest some clear pointers towards strategic public health communication efforts calling for communication campaigns towards audiences segmented by social class, race/ethnicity and beliefs, often what advertisers call "psychodemographics".

AB Aims: Cold stress has been shown to produce dramatic increases in 2-fluoro-2-deoxy-D-Glucose ((18)FDG) accumulation by brown adipose tissue (BAT) in rodents. However, neither the effects of other types of stress on (18)FDG accumulation nor the effects of stressors on the accumulation of tracers of other aspects of energy metabolism have been evaluated. In this report we studied the effects of cold stress, burn injury and cutaneous wounds on murine BAT at the macroscopic, microscopic and metabolic level.
Main methods: Glucose metabolism was studied with (18)FDG, fatty acid accumulation was evaluated with trans-9(RS)-(18)F-fluoro-3,4(RS,RS)-methyleneheptadecanoic acid (FCPHA) and tricarboxcylic acid cycle (TCA) activity was evaluated with (3)H acetate.
Key findings: All three stressors produced dramatic changes in BAT at the macroscopic and microscopic level. Macroscopically, BAT from the stressed animals appeared to be a much darker brown in color. Microscopically BAT of stressed animals demonstrated significantly fewer lipid droplets and an overall decrease in lipid content. Accumulation of (18)FDG by BAT was significantly (p<0.01) increased by all 3 treatments (Cold: similar to 16 fold, burn similar to 7 Fold and cutaneous wound similar to 14 fold) whereas uptake of FDG by white fat was unchanged. This effect was also demonstrated non invasively by mu PET imaging. Although less prominent than with (18)FDG, BAT uptake of FCPHA and acetate were also significantly increased by all three treatments. These findings suggest that in addition to cold stress, burn injury and cutaneous wounds produce BAT activation in mice.
Significance: This study demonstrates brown fat activated by several stressors leads to increased uptake of various substrates. (C) 2011 Elsevier Inc. All rights reserved.

AB Background: A direct pharmacological stimulation of soluble guanylate cyclase (sGC) is an emerging therapeutic approach to the management of various cardiovascular disorders associated with endothelial dysfunction. Novel sGC stimulators, including riociguat (BAY 63-2521), have a dual mode of action: They sensitize sGC to endogenously produced nitric oxide (NO) and also directly stimulate sGC independently of NO. Little is known about their effects on tissue remodeling and degeneration and survival in experimental malignant hypertension.
Methods and Results: Mortality, hemodynamics and biomarkers of tissue remodeling and degeneration were assessed in Dahl salt-sensitive rats maintained on a high salt diet and treated with riociguat (3 or 10 mg/kg/d) for 14 weeks. Riociguat markedly attenuated systemic hypertension, improved systolic heart function and increased survival from 33% to 85%. Histological examination of the heart and kidneys revealed that riociguat significantly ameliorated fibrotic tissue remodeling and degeneration. Correspondingly, mRNA expression of the pro-fibrotic biomarkers osteopontin (OPN), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) and plasminogen activator inhibitor-1 (PAI-1) in the myocardium and the renal cortex was attenuated by riociguat. In addition, riociguat reduced plasma and urinary levels of OPN, TIMP-1, and PAI-1.
Conclusions: Stimulation of sGC by riociguat markedly improves survival and attenuates systemic hypertension and systolic dysfunction, as well as fibrotic tissue remodeling in the myocardium and the renal cortex in a rodent model of pressure and volume overload. These findings suggest a therapeutic potential of sGC stimulators in diseases associated with impaired cardiovascular and renal functions.

TI Relation of Body Mass Index to Urinary Creatinine Excretion Rate in

AB In patients with prevalent coronary heart disease (CHD), studies have found a paradoxical relation in that patients with higher body mass indexes (BMIs) have lower mortality. One possibility is that patients with higher BMIs have greater muscle mass, and higher BMI may be a marker of better overall health status. The aim of this study was to evaluate whether the paradoxical association of BMI with mortality in patients with CHD is attenuated when accounting for urinary creatinine excretion, a marker of muscle mass. The Heart and Soul Study is an observational study of outpatients with stable CHD. Outpatient 24-hour timed urine collections were obtained. Participants were followed up for death for 5.9 +/- 1.9 years. Cox proportional-hazards models were used to evaluate the association between gender-specific BMI quintiles and mortality. There were 886 participants in the study population. Participants in higher quintiles of BMI were younger, were more likely to have diabetes mellitus and hypertension, and had higher urinary creatinine excretion rate. Compared to the lowest BMI quintile, subjects in higher BMI quintiles were less likely to die during follow-up. Adjustment for major demographic variables, traditional cardiovascular risk factors, and kidney function did not attenuate the relation. Additional adjustment for urinary creatinine excretion rate did not materially change the association between BMI and all-cause mortality. In conclusion, low muscle mass and low BMI are each associated with greater all-cause mortality, but low muscle mass does not appear to explain why CHD patients with low BMIs have worse prognosis.

AB Reversal of pathogen-induced immunosuppression upon employment of effective antimicrobial therapy and withdrawal of iatrogenic immunosuppression has the potential to shift the host immune repertoire towards pathologic inflammatory responses conducive to immune reconstitution syndrome (IRS). Posttransplant IRS has been observed with fungi, M. tuberculosis, cytomegalovirus, and polyoma virus nephropathy. This review discusses the existing state of knowledge regarding IRS and the immune mechanisms that underlie its pathogenesis, with significant implications for developing reliable diagnostic biomarkers and optimal management strategies for post-transplant opportunistic infection-associated IRS.

TI Functional Mutation of SMAC/DIABLO, Encoding a Mitochondrial

AB SMAC/DIABLO is a mitochondrial proapoptotic protein that is released from mitochondria during apoptosis and counters the inhibitory activities of inhibitor of apoptosis proteins, IAPs. By linkage analysis and candidate screening, we identified a heterozygous SMAC/DIABLO mutation, c.377C>T (p.Ser126Leu, refers to p.Ser71Leu in the mature protein) in a six-generation Chinese kindred characterized by dominant progressive nonsyndromic hearing loss, designated as DFNA64. SMAC/DIABLO is highly expressed in human embryonic ears and is enriched in the developing mouse inner-ear hair cells, suggesting it has a role in the development and homeostasis of hair cells. We used a functional study to demonstrate that the SMAC/DIABLO(S71L) mutant, while retaining the proapoptotic function, triggers significant degradation of both wild-type and mutant SMAC/DIABLO and renders host mitochondria susceptible to calcium-induced loss of the membrane potential. Our work identifies DFNA64 as the human genetic disorder associated with SMAC/DIABLO malfunction and suggests that mutant SMAC/DIABLO(S71L) might cause mitochondrial dysfunction.

AB The cingulate cortex frequently shows gray matter loss with age as well as gender differences in structure and function, but little is known about whether individual cingulate Brodmann areas show gender-specific patterns of age-related volume decline. This study examined age-related changes, gender differences, and the interaction of age and gender in the relative volume of cingulate gray matter in areas 25, 24, 31, 23, and 29, over seven decades of adulthood. Participants included healthy, age-matched men and women, aged 20-87 (n=70). Main findings were as follows: (1) The whole cingulate showed significant age-related volume declines (averaging 5.54% decline between decades, 20s-80s). Each of the five cingulate areas also showed a significant decline with age, and individual areas showed different patterns of decline across the decades: Smaller volume with age was most evident in area 31, followed by 25 and 24. (2) Women had relatively larger cingulate gray matter volume than men overall and in area 24. (3) Men and women showed different patterns of age-related volume decline in area 31, at midlife and late in life. By delineating normal gender differences and age-related morphometric changes in the cingulate cortex over seven decades of adulthood, this study improves the baseline for comparison with structural irregularities in the cingulate cortex associated with psychopathology. The Brodmann area-based approach also facilitates comparisons across studies that aim to draw inferences between age- and gender-related structural differences in the cingulate gyrus and corresponding differences in cingulate function.

AB Cancer immunotherapy relies on the ability of the immune system to target tumor-specific antigens to generate an immune response. This initial response requires both binding of the MHC/antigen peptide to T-cell receptor complex, along with a second costimulatory signal created by the binding of CD28 on the T cell, with B7 located on the antigen-presenting cell. Regulatory checkpoints, such as cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), serve to attenuate this signal, thereby preventing autoimmunity. Its key role in regulating the immune system has made CTLA-4 an attractive therapeutic target for cancer, with the development of fully human monoclonal antibodies that have successfully targeted CTLA-4 in clinical trials. Augmentation of the immune response via blockade of CTLA-4 represents a significant advance in the field of oncology and has shown an improvement in survival for patients with metastatic melanoma. An increased understanding of the components of this pathway and the identification of other methods to modulate the immune system hold great promise for future therapy.

AB Purpose: Abiraterone is an oral inhibitor of CYP17, which is essential for androgen biosynthesis. This multicenter study assessed its efficacy in patients with castration-resistant prostate cancer (CRPC), without prior chemotherapy or CYP17-targeted therapy, and frequency of bone scans discordant with prostate-specific antigen (PSA) and clinical response.
Experimental Design: Thirty-three patients received abiraterone acetate 1,000 mg daily with prednisone 5 mg twice daily in continuous 28-day cycles. Patients were evaluated monthly for efficacy and safety. Bone scan flare was defined as the combination, after 3 months of therapy, of an interpreting radiologist's report indicating "disease progression" in context of a 50% or more decline in PSA level, with scan improvement or stability 3 months later.
Results: A 50% or more decline in PSA level at week 12 was confirmed in 22 of 33 (67%) patients. Declines in PSA level of 50% or more were seen in 26 of 33 (79%) patients. Undetectable PSA levels (<= 0.1 ng/mL) occurred in 2 patients. Median time on therapy and time to PSA progression were 63 weeks and 16.3 months, respectively. Twenty-three patients were evaluable for bone scan flare. Progression was indicated in radiologist's report in 12 of 23 (52%), and 11 of 12 subsequently showed improvement or stability. As prospectively defined, bone scan flare was observed in 11 of 23 (48%) evaluable patients or 11 of 33 (33%) enrolled patients. Adverse events were typically grade 1/2 and consistent with prior published abiraterone reports.
Conclusion: Clinical responses to abiraterone plus prednisone were frequent and durable in men with metastatic CRPC. Further investigation is needed to clarify the confounding effect of bone scan flare on patient management and interpretation of results. Clin Cancer Res; 17(14); 4854-61. (C)2011 AACR.

AB Purpose: VEGF and infiltrating myeloid cells are known regulators of tumor angiogenesis and vascular permeability in glioblastoma. We investigated potential blood-based markers associated with radiographic changes to aflibercept, which binds VEGF and placental growth factor (PlGF) in patients with recurrent glioblastoma.
Experimental Design: In this single-arm phase II trial, aflibercept was given intravenously every two weeks until disease progression. Plasma and peripheral blood mononuclear cells were collected at baseline and 24 hours, 14 days, and 28 days posttreatment. Plasma cytokines and angiogenic factors were quantified by using ELISA and multiplex bead assays, and myeloid cells were assessed by flow cytometry in a subset of patients.
Results: Circulating levels of VEGF significantly decreased 24 hours after treatment with aflibercept, coincident with radiographic response observed by MRI. PlGF initially decreased 24 hours posttreatment but increased significantly by days 14 and 28. Lower baseline levels of PlGF, elevated baseline levels of CTACK/CCL27, MCP3/CCL7, MIF, and IP-10/CXCL10, and a decrease in VEGFR1(+) monocytes from baseline to 24 hours were all associated with improved response. Tumor progression was associated with increases in circulating matrix metalloproteinase 9.
Conclusions: These data suggest that decreases in VEGF posttreatment are associated with radiographic response to aflibercept. Elevated baseline chemokines of monocyte lineage in responding patients supports a role for myeloid cells and chemokines as potential biomarkers and regulators of glioma angiogenesis.

AB Women with BRCA1 mutations develop breast cancer with similar pathologic features to sporadic triple negative (TN) breast cancer, a subtype associated with early disease relapse and poor outcome. The clinical outcome of women with and without BRCA1 mutations who had TN breast cancer treated with conventional chemotherapy were compared. METHODS: Women with stage I to III TN breast cancer who had BRCA1 testing within 36 months of diagnosis and received alkylating chemotherapy were identified from clinical databases and a Specialized Program of Research Excellence (SPORE) specimen bank. EIRCA2 mutation carriers were excluded, resulting in a study cohort of 46 BRCA1 carriers and 71 noncarriers. Sites of metastasis, relapse rates, and survival were compared among carriers and noncarriers. The median follow-up was 75 months. RESULTS: BRCA1 carriers were younger at diagnosis (P < .001) and had smaller tumors (P = .03) than noncarriers. Freedom from distant metastasis at 5 years was 76% for carriers and 70% for noncarriers (hazard ratio [HP] 0.79, P = .5). Sites of distant recurrence did not differ significantly (P = .15), although BRCA1 carriers had a propensity for brain relapse (58% vs 24%, P = .06). Overall survival at 5 years was 82% for carriers and 74% for noncarriers (HR 0.64, P = .25). Adjusting for age and stage, BRCA1 mutation status was not an independent predictor of survival (HR 0.73, P = .48). CONCLUSIONS: BRCA1 mutation carriers with TN disease had similar survival rates to noncarriers when treated with alkylating chemotherapy. Women with BRCA1-related breast cancer may benefit from novel therapies that target DNA repair, and further study is needed to identify sporadic TN breast cancers with a BRCA-deficient phenotype.

AB The STAT3 transcription factor is an important regulator of stem cell self-renewal, cancer cell survival, and inflammation. In the pancreas, STAT3 is dispensable for normal development, whereas the majority of pancreatic ductal adenocarcinomas (PDAC) show constitutive activation of STAT3, suggesting its potential as a therapeutic target in this cancer. Here, we sought to define the mechanisms of STAT3 activation and its functional importance in PDAC pathogenesis. Large-scale screening of cancer cell lines with a JAK2 inhibitor that blocks STAT3 function revealed a more than 30-fold range in sensitivity in PDAC, and showed a close correlation of sensitivity with levels of tyrosine-phosphorylated STAT3 and of the gp130 receptor, an upstream signaling component. Correspondingly, upregulation of the IL6/LIF-gp130 pathway accounted for the strong STAT3 activation in PDAC subsets. To define functions of STAT3 in vivo, we developed mouse models that test the impact of conditional inactivation of STAT3 in KRAS-driven PDAC. We showed that STAT3 is required for the development of the earliest premalignant pancreatic lesions, acinar-to-ductal metaplasia (ADM) and pancreatic intraepithelial neoplasia (PanIN). Moreover, acute STAT3 inactivation blocked PDAC initiation in a second in vivo model. Our results show that STAT3 has critical roles throughout the course of PDAC pathogenesis, supporting the development of therapeutic approaches targeting this pathway. Moreover, our work suggests that gp130 and phospho-STAT3 expression may be effective biomarkers for predicting response to JAK2 inhibitors. Cancer Res; 71(14); 5020-9. (C)2011 AACR.

AB Small cell lung cancer (SCLC) is an aggressive cancer often diagnosed after it has metastasized. Despite the need to better understand this disease, SCLC remains poorly characterized at the molecular and genomic levels. Using a genetically engineered mouse model of SCLC driven by conditional deletion of Trp53 and Rb1 in the lung, we identified several frequent, high-magnitude focal DNA copy number alterations in SCLC. We uncovered amplification of a novel, oncogenic transcription factor, Nuclear factor I/B (Nfib), in the mouse SCLC model and in human SCLC. Functional studies indicate that NFIB regulates cell viability and proliferation during transformation.

AB Huntington's disease is initiated by the expression of a CAG repeat-encoded polyglutamine region in full-length huntingtin, with dominant effects that vary continuously with CAG size. The mechanism could involve a simple gain of function or a more complex gain of function coupled to a loss of function (e. g. dominant negative-graded loss of function). To distinguish these alternatives, we compared genome-wide gene expression changes correlated with CAG size across an allelic series of heterozygous CAG knock-in mouse embryonic stem (ES) cell lines (Hdh(Q20/7), Hdh(Q50/7), Hdh(Q91/7), Hdh(Q111/7)), to genes differentially expressed between Hdh(ex4/5/ex4/5) huntingtin null and wild-type (Hdh(Q7/7)) parental ES cells. The set of 73 genes whose expression varied continuously with CAG length had minimal overlap with the 754-member huntingtin-null gene set but the two were not completely unconnected. Rather, the 172 CAG length-correlated pathways and 238 huntingtin-null significant pathways clustered into 13 shared categories at the network level. A closer examination of the energy metabolism and the lipid/sterol/lipoprotein metabolism categories revealed that CAG length-correlated genes and huntingtin-null-altered genes either were different members of the same pathways or were in unique, but interconnected pathways. Thus, varying the polyglutamine size in full-length huntingtin produced gene expression changes that were distinct from, but related to, the effects of lack of huntingtin. These findings support a simple gain-of-function mechanism acting through a property of the full-length huntingtin protein and point to CAG-correlative approaches to discover its effects. Moreover, for therapeutic strategies based on huntingtin suppression, our data highlight processes that may be more sensitive to the disease trigger than to decreased huntingtin levels.

AB Purpose: The German rectal study determined that preoperative radiation therapy (RT) as a component of combined-modality therapy decreased local tumor recurrence, increased sphincter preservation, and decreased treatment toxicity compared with postoperative RT for rectal cancer. We evaluated the use of preoperative RT after the presentation of the landmark German rectal study results and examined the impact of tumor and sociodemographic factors on receiving preoperative RT.
Methods and Materials: In total, 20,982 patients who underwent surgical resection for T3-T4 and/or node-positive rectal adenocarcinoma diagnosed from 2000 through 2006 were identified from the Surveillance, Epidemiology, and End Results tumor registries. We analyzed trends in preoperative RT use before and after publication of the findings from the German rectal study. We also performed multivariate logistic regression to identify factors associated with receiving preoperative RT.
Results: Among those treated with RT, the proportion of patients treated with preoperative RT increased from 33.3% in 2000 to 63.8% in 2006. After adjustment for age; gender; race/ethnicity; marital status; Surveillance, Epidemiology, and End Results registry; county-level education; T stage; N stage; tumor size; and tumor grade, there was a significant association between later year of diagnosis and an increase in preoperative RT use (adjusted odds ratio, 1.26/y increase; 95% confidence interval, 1.23-1.29). When we compared the years before and after publication of the German rectal study (2000-2003 vs. 2004-2006), patients were more likely to receive preoperative RT than postoperative RT in 2004-2006 (adjusted odds ratio, 2.35; 95% confidence interval, 2.13-2.59). On multivariate analysis, patients who were older, who were female, and who resided in counties with lower educational levels had significantly decreased odds of receiving preoperative RT.
Conclusions: After the publication of the landmark German rectal study, there was widespread, rapid adoption of preoperative RT for locally advanced rectal cancer. However, preoperative RT may be underused in certain sociodemographic groups. (C) 2011 Elsevier Inc.

AB The 5-hydroxytryptamine 2A receptor (5-HT2AR) undergoes constitutive and agonist-dependent internalization. Despite many advances in our understanding of G protein-coupled receptor trafficking, the exact mechanism of endocytic sorting of G protein-coupled receptors remains obscure. Recently, we have reported a novel finding documenting a global role for the ubiquitin ligase c-Cbl in regulating vesicular sorting of epidermal growth factor receptor (Baldys, A., Gooz, M., Morinelli, T. A., Lee, M. H., Raymond, J. R., Jr., Luttrell, L. M., and Raymond, J. R., Sr. (2009) Biochemistry 48, 1462-1473). Thus, we tested the hypothesis that c-Cbl might play a role in 5-HT2AR recycling. In this study, we demonstrated an association of 5-HT2AR with c-Cbl. Furthermore, down-regulation of c-Cbl by RNA interference blocked efficient recycling of 5-HT2AR to the plasma membrane. Immunofluorescence microscopy revealed that 5-HT2A receptors were trapped in early endosome antigen 1- and Rab11-positive sorting endosomes in cells overexpressing c-Cbl mutants lacking carboxyl termini. This inhibitory effect was associated with a relative decrease in association of c-Cbl truncation proteins with the 5-HT2AR, compared with that observed for the full-length c-Cbl fusion protein. Consistent with the delayed recycling, 5-HT2AR resensitization was greatly attenuated in the presence of c-Cbl mutants lacking carboxyl termini, as detected by changes in the cytosolic calcium. Taken together, these studies have led to the discovery that the C-terminal region of c-Cbl plays a crucial role in the temporal and spatial control of 5-HT2AR recycling.

AB The dihydroceramide desaturase (DES) enzyme is responsible for inserting the 4,5-trans-double bond to the sphingolipid backbone of dihydroceramide. We previously demonstrated that fenretinide (4-HPR) inhibited DES activity in SMS-KCNR neuroblastoma cells. In this study, we investigated whether 4-HPR acted directly on the enzyme in vitro. N-C8:0-D-erythro-dihydroceramide (C-8-dhCer) was used as a substrate to study the conversion of dihydroceramide into ceramide in vitro using rat liver microsomes, and the formation of tritiated water after the addition of the tritiated substrate was detected and used to measure DES activity. NADH served as a cofactor. The apparent K-m for C-8-dhCer and NADH were 1.92 +/- 0.36 mu M and 43.4 +/- 6.47 mu M, respectively; and the V-max was 3.16 +/- 0.24 and 4.11 +/- 0.18 nmol/min/g protein. Next, the effects of 4-HPR and its metabolites on DES activity were investigated. 4-HPR was found to inhibit DES in a dose-dependent manner. At 20 min, the inhibition was competitive; however, longer incubation times demonstrated the inhibition to be irreversible. Among the major metabolites of 4-HPR, 4-oxo-N-(4-hydroxyphenyl) retinamide (4-oxo-4-HPR) showed the highest inhibitory effect with substrate concentration of 0.5 mu M, with an IC50 of 1.68 mu M as compared with an IC50 of 2.32 mu M for 4-HPR. N-(4-Methoxyphenyl) retinamide (4-MPR) and 4-Oxo-N-(4-methoxyphenyl) retinamide (4-oxo-4-MPR) had minimal effects on DES activity. A known competitive inhibitor of DES, C-8-cyclopropenylceramide was used as a positive control. These studies define for the first time a direct in vitro target for 4-HPR and suggest that inhibitors of DES may be used as therapeutic interventions to regulate ceramide desaturation and consequent function.

AB Pancreatic cancer remains a devastating malignancy with a poor prognosis and is largely resistant to current therapies. To understand the resistance of pancreatic tumors to Fas death receptor-induced apoptosis, we investigated the molecular mechanisms of Fas-activated survival signaling in pancreatic cancer cells. We found that knockdown of the Fas-associated protein with death domain (FADD), the adaptor that mediates downstream signaling upon Fas activation, rendered Fas-sensitive MiaPaCa-2 and BxPC-3 pancreatic cells resistant to Fas-induced apoptosis. By contrast, Fas activation promoted the survival of the FADD knockdown MiaPaCa-2 and BxPC-3 cells in a concentration-dependent manner. The pharmacological inhibitor of ERK, PD98059, abrogated Fas-promoted cell survival in FADD knockdown MiaPaCa-2 and BxPC-3 cells. Furthermore, increased phosphorylation of Src was demonstrated to mediate Fas-induced ERK activation and cell survival. Immunoprecipitation of Fas in the FADD knockdown cells identified the presence of increased calmodulin, Src, and phosphorylated Src in the Fas-associated protein complex upon Fas activation. Trifluoperazine, a calmodulin antagonist, inhibited Fas-induced recruitment of calmodulin, Src, and phosphorylated Src. Consistently, trifluoperazine blocked Fas-promoted cell survival. A direct interaction of calmodulin and Src and their binding site were identified with recombinant proteins. These results support an essential role of calmodulin in mediating Fas-induced FADD-independent activation of Src-ERK signaling pathways, which promote survival signaling in pancreatic cancer cells. Understanding the molecular mechanisms responsible for the resistance of pancreatic cells to apoptosis induced by Fas-death receptor signaling may provide molecular insights into designing novel therapies to treat pancreatic tumors.

AB Myelodysplastic syndromes (MDS) are characterized by abnormal and dysplastic maturation of all blood lineages. Even though epigenetic alterations have been seen in MDS marrow progenitors, very little is known about the molecular alterations in dysplastic peripheral blood cells. We analyzed the methylome of MDS leukocytes by the HELP assay and determined that it was globally distinct from age-matched controls and was characterized by numerous novel, aberrant hypermethylated marks that were located mainly outside of CpG islands and preferentially affected GTPase regulators and other cancer-related pathways. Additionally, array comparative genomic hybridization revealed that novel as well as previously characterized deletions and amplifications could also be visualized in peripheral blood leukocytes, thus potentially reducing the need for bone marrow samples for future studies. Using integrative analysis, potentially pathogenic genes silenced by genetic deletions and aberrant hypermethylation in different patients were identified. DOCK4, a GTPase regulator located in the commonly deleted 7q31 region, was identified by this unbiased approach. Significant hypermethylation and reduced expression of DOCK4 in MDS bone marrow stem cells was observed in two large independent datasets, providing further validation of our findings. Finally, DOCK4 knockdown in primary marrow CD34(+) stem cells led to decreased erythroid colony formation and increased apoptosis, thus recapitulating the bone marrow failure seen in MDS. These findings reveal widespread novel epigenetic alterations in myelodysplastic leukocytes and implicate DOCK4 as a pathogenic gene located on the 7q chromosomal region.

AB QnrB1 is a plasmid-encoded pentapeptide repeat protein (PRP) that confers a moderate degree of resistance to fluoroquinolones. Its gene was cloned into an expression vector with an N-terminal polyhistidine tag, and the protein was purified by nickel affinity chromatography. The structure of QnrB1 was determined by a combination of trypsinolysis, surface mutagenesis, and single anomalous dispersion phasing. QnrB1 folds as a right-handed quadrilateral beta-helix with a highly asymmetric dimeric structure typical of PRP-topoisomerase poison resistance factors. The threading of pentapeptides into the beta-helical fold is interrupted by two noncanonical PRP sequences that produce outward projecting loops that interrupt the regularity of the PRP surface. Deletion of the larger upper loop eliminated the protective effect of QnrB1 on DNA gyrase toward inhibition by quinolones, whereas deletion of the smaller lower loop drastically reduced the protective effect. These loops are conserved among all plasmid-based Qnr variants (QnrA, QnrC, QnrD, and QnrS) and some chromosomally encoded Qnr varieties. A mechanism in which PRP-topoisomerase poison resistance factors bind to and disrupt the quinolone-DNA-gyrase interaction is proposed.

AB Reports suggest that excessive ceramide accumulation in mitochondria is required to initiate the intrinsic apoptotic pathway and subsequent cell death, but how ceramide accumulates is unclear. Here we report that liver mitochondria exhibit ceramide formation from sphingosine and palmitoyl-CoA and from sphingosine and palmitate. Importantly, this activity was markedly decreased in liver from neutral ceramidase (NCDase)-deficient mice. Moreover, the levels of ceramide were dissimilar in liver mitochondria of WT and NCDase KO mice. These results suggest that NCDase is a key participant of ceramide formation in liver mitochondria. We also report that highly purified liver mitochondria have ceramidase, reverse ceramidase, and thioesterase activities. Increased accessibility of palmitoyl-CoA to the mitochondrial matrix with the pore-forming peptide zervamicin IIB resulted in 2-fold increases in palmitoyl-CoA hydrolysis by thioesterase. This increased hydrolysis was accompanied by an increase in ceramide formation, demonstrating that both outer membrane and matrix localized thioesterases can regulate ceramide formation. Also, ceramide formation might occur both in the outer mitochondrial membrane and in the mitochondrial matrix, suggesting the existence of distinct ceramide pools. Taken together, these results suggest that the reverse activity of NCDase contributes to sphingolipid homeostasis in this organelle in vivo.

AB The purpose of this study was to investigate the neurological integrity and physiological status of the auditory brainstem tracts and nuclei in children with chronic lead (Pb) exposure using non-invasive acoustic stapedius reflex (ASR) measurements of afferent and efferent-neuromuscular auditory function. Following audiological examinations, uncrossed (ipsilateral) and crossed (contralateral) brainstem ASR responses were evoked by pure tone (500, 1000, and 2000 Hz), and broadband noise (bandwidth: 125-4000 Hz) stimulus activators. The ASR threshold (ASRT), amplitude growth, and decay/fatigue were measured by conventional clinical middle ear immittance methods in a group of Andean children (age range: 2-18 years) with a history of chronic environmental Pb exposure from occupational Pb glazing. Blood lead (PbB) levels of the study group (n = 117) ranged from 4.0 to 83.7 mu g/dL with a mean PbB level of 33.5 mu g/dL (SD: 23.6; median: 33.0: CDC III Classification). The PbB distribution data indicated that 77.8% (n = 91) of the children had PbB levels greater than the CDC action line of 10 mu g/dL Repeatable, normal ASRTs were elicited for ipsilateral (mean: <= 90 dB HL) and contralateral (mean: <= 97dB HL) stimulation for each acoustic activator. Spearman Rho correlation analysis indicated no significant association between PbB level and ipsilateral or contralateral ASRT for any of the stimulus activators. The ASR amplitude growth results showed typical growth functions with no Pb-associated aberrations. No statistical association was found between ASR decay/adaptation (ASRD) and PbB level for any of the stimulus activators. The results of stapedius muscle reflex testing using several stimulus activators showed no significant relationship between PbB level and the physiological integrity of the auditory brainstem mediated ASR responses in children with chronic Pb exposure and elevated PbB levels.

AB Ceramide is a potent pro-inflammatory sphingolipid recently shown to exert potent hyperalgesic responses in rats. Once generated, ceramide is converted by sphingosine kinase (SphK) 1 and/or 2 to one of its active metabolite sphingosine-1-phosphate (SIP), which in turn signals through G-protein coupled S1P receptors. The objectives of this paper were to define whether ceramide-induced hyperalgesia is driven by S1P. Our results show that intraplantar injection of ceramide in rats led to a time-dependent development of thermal hyperalgesia that was associated with an increase in tumor necrosis factor-a (TNF-alpha) in paw tissues. The development of hyperalgesia was significantly attenuated by a soluble TNF receptor I. TNF-alpha is known to activate SphK1, thus SIP production, and our results demonstrate that, the development of hyperalgesia was attenuated in a dose-dependent fashion by a well characterized inhibitor of SphK1 and SphK2 (SK-I) and by a murine monoclonal anti-SI P antibody (LT1002). LT1017, the isotype-matched control monoclonal antibody for LT1002, had no effect. Our results further demonstrate that SIP contributes to the development of hyperalgesia via the SIP receptor 1 subtype (S1PR(1)), since responses were blocked by a well characterized S1PR(1) antagonist, W146, but not by its inactive enantiomer, W140. Collectively, these results provide mechanistic evidence implicating the S1P-to-S1PR(1) pathway as a downstream signaling pathway in ceramide-induced hyperalgesia. Targeting SIP may be a novel therapeutic approach in pain management. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

AB In hyperpolarized xenon magnetic resonance imaging (HP Xe-129 MRI), the inhaled spin-1/2 isotope of xenon gas is used to generate the MR signal. Because hyperpolarized xenon is an MR signal source with properties very different from those generated from water-protons, HP Xe-129 MRI may yield structural and functional information not detectable by conventional proton-based MRI methods. Here we demonstrate the differential distribution of HP Xe-129 in the cerebral cortex of the rat following a pain stimulus evoked in the animal's forepaw. Areas of higher HP Xe-129 signal corresponded to those areas previously demonstrated by conventional functional MRI (fMRI) methods as being activated by a forepaw pain stimulus. The percent increase in HP Xe-129 signal over baseline was 13-28%, and was detectable with a single set of pre and post stimulus images. Recent innovations in the production of highly polarized Xe-129 should make feasible the emergence of HP Xe-129 MRI as a viable adjunct method to conventional MRI for the study of brain function and disease.

AB The integrated analysis of genotypic and expression data for association with complex traits could identify novel genetic pathways involved in complex traits. We profiled 19,573 expression probes in Epstein-Barr virus-transformed lymphoblastoid cell lines (LCLs) from 299 twins and correlated these with 44 quantitative traits (QTs). For 939 expressed probes correlating with more than one QT, we investigated the presence of eQTL associations in three datasets of 57 CEU HapMap founders and 86 unrelated twins. Genome-wide association analysis of these probes with 2.2 m SNPs revealed 131 potential eQTLs (1,989 eQTL SNPs) overlapping between the HapMap datasets, five of which were in cis (58 eQTL SNPs). We then tested 535 SNPs tagging the eQTL SNPs, for association with the relevant QT in 2,905 twins. We identified nine potential SNP-QT associations (P<0.01) but none significantly replicated in five large consortia of 1,097-16,129 subjects. We also failed to replicate previous reported eQTL associations with body mass index, plasma low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglycerides levels derived from lymphocytes, adipose and liver tissue. Our results and additional power calculations suggest that proponents may have been overoptimistic in the power of LCLs in eQTL approaches to elucidate regulatory genetic effects on complex traits using the small datasets generated to date. Nevertheless, larger tissue-specific expression data sets relevant to specific traits are becoming available, and should enable the adoption of similar integrated analyses in the near future.

AB Parkinson's disease is one of the major neurodegenerative disorders. Neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) can cause Parkinson's disease like symptoms and biochemical changes in humans and animals. Hydrogen sulfide (H(2)S) has been shown to protect neurons. The goal of this study was to examine the effects of inhaled H(2)S in a mouse model of Parkinson's disease induced by MPTP. Male C57BL/6J mice received MPTP at 80 mg/kg and breathed air with or without 40 ppm H(2)S for 8 h/day for 7 days. Administration of MPTP induced movement disorder and decreased tyrosine hydroxylase (TH)-containing neurons in the substantia nigra and striatum in mice that breathed air. Inhalation of H(2)S prevented the MPTP-induced movement disorder and the degeneration of TH-containing neurons. Inhaled H(2)S also prevented apoptosis of the TH-containing neurons and gliosis in nigrostriatal region after administration of MPTP. The neuroprotective effect of inhaled H(2)S after MPTP administration was associated with upregulation of genes encoding antioxidant proteins, including heme oxygenase-1 and glutamate-cysteine ligase. These observations suggest that inhaled H(2)S prevents neurodegeneration in a mouse model of Parkinson's disease induced by MPTP, potentially via upregulation of antioxidant defense mechanisms and inhibition of inflammation and apoptosis in the brain.

AB Aims Human congenital heart disease linked to mutations in the homeobox transcription factor, NKX2-5, is characterized by cardiac anomalies, including atrial and ventricular septal defects as well as conduction and occasional defects in contractility. In the mouse, homozygous germline deletion of Nkx2-5 gene results in death around E10.5. It is, however, not established whether Nkx2-5 is necessary for cardiac development beyond this embryonic stage. Because human NKX2-5 mutations are related to septum secundum type atrial septal defects (ASD), we hypothesized that Nkx2-5 deficiency during the processes of septum secundum formation may cause cardiac anomalies; thus, we analysed mice with tamoxifen-inducible Nkx2-5 ablation beginning at E12.5 when the septum secundum starts to develop.
Methods and results Using tamoxifen-inducible Nkx2-5 gene-targeted mice, this study demonstrates that Nkx2-5 ablation beginning at E12.5 results in embryonic death by E17.5. Analysis of mutant embryos at E16.5 shows arrhythmias, contraction defects, and cardiac malformations, including ASD. Quantitative measurements using serial section histology and three-dimensional reconstruction demonstrate growth retardation of the septum secundum and enlarged foramen ovale in Nkx2-5-ablated embryos. Functional cardiac defects may be attributed to abnormal expression of transcripts critical for conduction and contraction, including cardiac voltage-gated Na(+) channel pore-forming alpha-subunit (Na(v)1.5-alpha), gap junction protein connexin40, cardiac myosin light chain kinase, and sarcolipin within 4 days after tamoxifen injection.
Conclusion Nkx2-5 is necessary for survival after the mid-embryonic stage for cardiac function and formation by regulating the expression of its downstream target genes.

AB Study Design. Retrospective literature review.
Objective. To assess the quality of randomized controlled trial reporting in spine surgery.
Summary of Background Data. The use of the Consolidated Standards of Reporting Trials (CONSORT) criteria in clinical trials aims to improve adherence to a set of generally accepted practices in the reporting of randomized controlled trials. Randomized controlled trials in spine surgery are important sources of evidence-based practice, but the quality of their execution and reporting have not been reported adequately.
Methods. All randomized controlled trials published in three selected dedicated spine journals from 2008 were reviewed with respect to the 40 criteria derived from CONSORT descriptors; 10 criteria applying to the abstract, and 30 to the body of the article. Each article was scored by three reviewers in group format for each criterion and was assigned a score. Reviewers always came to a consensus before assigning a score.
Results. A total of 32 RCTs met the inclusion criteria for this review. The average modified CONSORT score was 65%. Disclosing certain criteria was associated with a higher overall score, including method of generation of random sequence (P < 0.000071), allocation concealment (P < 0.00014), inclusion of a flow chart or description of patient numbers at different stages (P < 0.00034), and identification of outcome measures (P < 0.00064).
Conclusion. Conclusions drawn from current randomized controlled trials in the spine literature may thus be difficult to interpret. Greater effort must be put into compliance with these guidelines to improve data quality.

TI Lethal Forethought: Delayed Reward Discounting Differentiates High- and

AB Background: The decision to commit suicide may be impulsive, but lethal suicidal acts often involve planning and forethought. People who attempt suicide make disadvantageous decisions in other contexts, but nothing is known about the way they decide about the future. Can the willingness to postpone future gratification differentiate between individuals prone to serious, premeditated and less serious, unplanned suicidal acts?
Methods: Four groups of depressed participants aged 60 and older made choices between smaller immediate and larger delayed monetary rewards: 15 who had made high-lethality suicide attempts, 14 who had made low-lethality suicide attempts, 12 who seriously contemplated suicide, and 42 people with depression, but no history of suicidal thoughts. The reference group was 31 psychiatrically healthy elders.
Results: Individuals who had made low-lethality attempts displayed an exaggerated preference for immediate rewards compared with nonsuicidal depressed and healthy control subjects. Those who had carried out high-lethality suicide attempts were more willing to delay future rewards, compared with low-lethality attempters. Better planned suicide attempts were also associated with willingness to wait for larger rewards. These effects were unchanged after accounting for education, global cognitive function, substance use disorders, psychotropic medications, and possible brain injury from attempts. Discount rates were correlated with having debt, but were not significantly associated with income, hopelessness, depressive severity, premorbid IQ, age at first attempt, or choice of violent means.
Conclusions: Although clinicians often focus on impulsivity in patients at risk for suicide, these data suggest that identifying biological characteristics and treatments for nonimpulsive suicidal older people may be even more important.

AB Background: Abnormalities in glutamatergic neurotransmission are implicated in several psychiatric disorders, but in vivo neurochemical studies of the glutamate (Glu) system have been hampered by a lack of adequate probes. By contrast, glutamine (Gln) and Glu can be quantified separately in proton magnetic resonance spectroscopy studies in vivo. Accumulating evidence suggests that the Gln/Glu ratio is a putative index of glutamatergic neurotransmission but interpretation of changes in the Gln/Glu ratio depends on the conditions of the system, including ammonia levels.
Methods: Here, we explored whether variation in GLS1 (the gene encoding the brain isoform of glutaminase, which catalyzes Gln-to-Glu conversion) is associated with Gln/Glu measured in vivo in two brain regions (anterior cingulate cortex, parieto-occipital cortex).
Results: A specific haplotype of four single nucleotide polymorphisms within GLS1 was significantly associated with Gln/Glu in the parieto-occipital cortex in an magnetic resonance spectroscopy-genetics dataset optimized for Gln/Glu detection (n = 42). This finding was replicated in a second magnetic resonance spectroscopy dataset that was optimized for gamma-aminobutyric acid detection where Gln and Glu measurements could still be extracted (n = 40).
Conclusions: These findings suggest that genetic variation in a key component of glutamatergic machinery is associated with a putative in vivo index of glutamatergic neurotransmission. Thus, GLS1 genotype might provide insight into normal brain function and into the pathophysiology of many psychiatric conditions where glutamatergic neurotransmission has been implicated. It might also serve as a biomarker for predicting response to existing and novel therapeutic interventions in psychiatry that target glutamatergic neurotransmission.

AB Histone deacetylases (HDACs) are enzymes involved in many important biological functions. They have been linked to a variety of cancers, psychiatric disorders, and other diseases. Since small molecules can serve as probes to study the relevant biological roles of HDACs, novel scaffolds are necessary to develop more efficient, selective drug candidates. Screening libraries of molecules may yield structurally diverse probes that bind these enzymes and modulate their functions in cells. Here we report a small molecule with a novel hydroxy-pyrimidine scaffold that inhibits multiple HDAC enzymes and modulates acetylation levels in cells. Analogs were synthesized in an effort to evaluate structure-activity relationships. (C) 2011 Elsevier Ltd. All rights reserved.

AB Spinal cord regenerative ability is lost with development, but the mechanisms underlying this loss are still poorly understood. In chick embryos, effective regeneration does not occur after E13, when spinal cord injury induces extensive apoptotic response and tissue damage. As initial experiments showed that treatment with a calcium chelator after spinal cord injury reduced apoptosis and cavitation, we hypothesized that developmentally regulated mediators of calcium-dependent processes in secondary injury response may contribute to loss of regenerative ability. To this purpose we screened for such changes in chick spinal cords at stages of development permissive (E11) and non-permissive (E15) for regeneration. Among the developmentally regulated calcium-dependent proteins identified was PAD3, a member of the peptidylarginine deiminase (PAD) enzyme family that converts protein arginine residues to citrulline, a process known as deimination or citrullination. This post-translational modification has not been previously associated with response to injury. Following injury, PAD3 up-regulation was greater in spinal cords injured at E15 than at E11. Consistent with these differences in gene expression, deimination was more extensive at the non-regenerating stage, E15, both in the gray and white matter. As deimination paralleled the extent of apoptosis, we investigated the effect of blocking PAD activity on cell death and deiminated-histone 3, one of the PAD targets we identified by mass-spectrometry analysis of spinal cord deiminated proteins. Treatment with the PAD inhibitor, Cl-amidine, reduced the abundance of deiminated-histone 3, consistent with inhibition of PAD activity, and significantly reduced apoptosis and tissue loss following injury at E15. Altogether, our findings identify PADs and deimination as developmentally regulated modulators of secondary injury response, and suggest that PADs might be valuable therapeutic targets for spinal cord injury.

AB It has been widely known that slow metabolism induced by calorie restriction (CR) can extend the life span of model organisms though the underlying mechanism remains poorly understood. Accumulated evidence suggests that SIRT1 may be actively involved in CR-induced signaling pathways. As a putative activator of SIRT1, resveratrol, known for the French paradox, can partially mimic the physiological effects of CR. While the deacetylase activity of SIRT1 is important for the beneficial effects of resveratrol, resveratrol-induced SIRT1 activation has recently been challenged by the observations that resveratrol could not induce SIRT1-mediated deacetylation of native substrates in vitro. To resolve the discrepancy of resveratrol-induced activation of SIRT1 deacetylase activity between the in vitro and in vivo assays, a model of indirect SIRT1 activation by resveratrol is proposed. In this review, we will discuss the emerging roles of SIRT1 and resveratrol in CR and focus on debate over the links between SIRT1 and resveratrol. (C) 2011 Elsevier Inc. All rights reserved.

AB Variation in genetic background can significantly influence the phenotypic outcome of both disease and non-disease associated traits. Additionally, differences in temporal and strain specific gene expression can also contribute to phenotypes in the mammalian retina. This is the first report of microarray based cross-strain analysis of gene expression in the retina investigating genetic background effects. Microarray analyses were performed on retinas from the following mouse strains: C57BL6/J, AKR/J, CAST/EiJ, and NOD. NON-H2(-nb1) at embryonic day 18.5 (E18.5) and postnatal day 30.5 (P30.5). Over 3000 differentially expressed genes were identified between strains and developmental stages. Differential gene expression was confirmed by qRT-PCR, Western blot, and immunohistochemistry. Three major gene networks were identified that function to regulate retinal or photoreceptor development, visual perception, cellular transport, and signal transduction. Many of the genes in these networks are implicated in retinal diseases such as bradyopsia, night-blindness, and cone-rod dystrophy. Our analysis revealed strain specific variations in cone photoreceptor cell patterning and retinal function. This study highlights the substantial impact of genetic background on both development and function of the retina and the level of gene expression differences tolerated for normal retinal function.

In addition, this study will provide valuable insight for the development of more accurate models for human retinal diseases.

AB CD52 is expressed on malignant cells in lymphoplasmacytic lymphoma (LPL), including IgM-secreting Waldenstrom macroglobulinemia (WM). We examined the activity of alemtuzumab in 28 symptomatic LPL (27 IgM and 1 IgA) patients. The median prior number of therapies for these patients was 2 (range, 0-5) and 43% had refractory disease. Patients received alemtuzumab at 30 mg IV 3 times weekly for up to 12 weeks after test dosing, and also received hydrocortisone, acyclovir, and Bactrim or equivalent prophylaxis. Patients had a complete response (n = 1), a partial response (n = 9), or a MR (n = 11) for an overall and major response rate of 75% and 36%, respectively. Median serum Ig decreased from 3510 to 1460 mg/dL (P < .001 at best response). With a median follow-up of 64 months, the median time to progression was 14.5 months. Hematologic and infectious complications, including CMV reactivation, were more common in previously treated patients and were indirectly associated with 3 deaths. Long-term follow-up revealed late-onset autoimmune thrombocytopenia (AITP) in 4 patients at a median of 13.6 months after therapy, which contributed to 1 death. Alemtuzumab is an active therapy in patients with LPL, but short-and long-term toxicities need to be carefully weighed against other available treatment options. Late AITP is a newly recognized complication of alemtuzumab in this patient population. This study is registered at www.clinicaltrials.gov as NCT00142181. (Blood.2011;118(2):276-281)

AB The Blood and Marrow Transplant Clinical Trials Network conducted 2 parallel multicenter phase 2 trials for individuals with leukemia or lymphoma and no suitable related donor. Reduced intensity conditioning (RIC) was used with either unrelated double umbilical cord blood (dUCB) or HLA-haploidentical related donor bone marrow (Haplo-marrow) transplantation. For both trials, the transplantation conditioning regimen incorporated cyclophosphamide, fludarabine, and 200 cGy of total body irradiation. The 1-year probabilities of overall and progression-free survival were 54% and 46%, respectively, after dUCB transplantation (n = 50) and 62% and 48%, respectively, after Haplo-marrow transplantation (n = 50). The day +56 cumulative incidence of neutrophil recovery was 94% after dUCB and 96% after Haplo-marrow transplantation. The 100-day cumulative incidence of grade II-IV acute GVHD was 40% after dUCB and 32% after Haplo-marrow transplantation. The 1-year cumulative incidences of non-relapse mortality and relapse after dUCB transplantation were 24% and 31%, respectively, with corresponding results of 7% and 45%, respectively, after Haplo-marrow transplantation. These multicenter studies confirm the utility of dUCB and Haplo-marrow as alternative donor sources and set the stage for a multicenter randomized clinical trial to assess the relative efficacy of these 2 strategies. The trials are registered at www.clinicaltrials.gov under NCT00864227 (BMT CTN 0604) and NCT00849147 (BMT CTN 0603). (Blood.2011;118(2):282-288)

AB Studying human antigen-specific memory B cells has been challenging because of low frequencies in peripheral blood, slow proliferation, and lack of antibody secretion. Therefore, most studies have relied on conversion of memory B cells into antibody-secreting cells by in vitro culture. To facilitate direct ex vivo isolation, we generated fluorescent antigen tetramers for characterization of memory B cells by using tetanus toxoid as a model antigen. Brightly labeled memory B cells were identified even 4 years after last immunization, despite low frequencies ranging from 0.01% to 0.11% of class-switched memory B cells. A direct comparison of monomeric to tetrameric antigen labeling demonstrated that a substantial fraction of the B-cell repertoire can be missed when monomeric antigens are used. The specificity of the method was confirmed by antibody reconstruction from single-cell sorted tetramer(+) B cells with single-cell RT-PCR of the B-cell receptor. All antibodies bound to tetanus antigen with high affinity, ranging from 0.23 to 2.2 nM. Furthermore, sequence analysis identified related memory B cell and plasmablast clones isolated more than a year apart. Therefore, antigen tetramers enable specific and sensitive ex vivo characterization of rare memory B cells as well as the production of fully human antibodies. (Blood.2011;118(2):348-357)

AB We have shown that Alox5 is a critical regulator of leukemia stem cells (LSCs) in a BCR-ABL-induced chronic myeloid leukemia (CML) mouse model, and we hypothesize that the Alox5 pathway represents a major molecular network that regulates LSC function. Therefore, we sought to dissect this pathway by comparing the gene expression profiles of wild type and Alox5(-/-) LSCs. DNA microarray analysis revealed a small group of candidate genes that exhibited changes in the levels of transcription in the absence of Alox5 expression. In particular, we noted that the expression of the Msr1 gene was upregulated in Alox5(-/-) LSCs, suggesting that Msr1 suppresses the proliferation of LSCs. Using CML mouse model, we show that Msr1 is downregulated by BCR-ABL and this down-regulation is partially restored by Alox5 deletion, and that Msr1 deletion causes acceleration of CML development. Moreover, Msr1 deletion markedly increases LSC function through its effects on cell cycle progression and apoptosis. We also show that Msr1 affects CML development by regulating the PI3K-AKT pathway and beta-Catenin. Together, these results demonstrate that Msr1 suppresses LSCs and CML development. The enhancement of the tumor suppressor function of Msr1 may be of significance in the development of novel therapeutic strategies for CML. (Blood.2011;118(2):390-400)

AB Tetraspanin protein CD151 on tumor cells supports invasion and metastasis. In the present study, we show that host animal CD151 also plays a critical role. CD151-null mice showed markedly diminished experimental lung metastasis after injection of Lewis lung carcinoma or B16F10 melanoma cells. Diminished tumor cell residence in the lungs was evident 6-24 hours after injection. Consistent with an endothelial cell deficiency, isolated CD151-null mouse lung endothelial cells showed diminished support for B16F10 adhesion and transendothelial migration, diminished B16F10-induced permeability, and diminished B16F10 adhesion to extracellular matrix deposited by CD151-null mouse lung endothelial cells. However, CD151 deletion did not affect the size of metastatic foci or subcutaneous primary B16F10 tumors, tumor aggregation, tumor clearance from the blood, or tumor-induced immune cell activation and recruitment. Therefore, the effects of host CD151 on metastasis do not involve altered local tumor growth or immune surveillance. VEGF-induced endothelial cell signaling through Src and Akt was diminished in CD151-null endothelial cells. However, deficient signaling was not accompanied by reduced endothelial permeability either in vitro (monolayer permeability assay) or in vivo (VEGF-stimulated Miles assay). In summary, diminished metastasis in CD151-null host animals may be due to impaired tumor-endothelial interactions, with underlying defects in mouse lung endothelial cell extracellular matrix production.

AB Although Caenorhabditis elegans has been utilized extensively to study synapse formation and function, relatively little is known about synaptic plasticity in C. elegans. We show that a brief treatment with the cholinesterase inhibitor aldicarb induces a form of presynaptic potentiation whereby ACh release at neuromuscular junctions (NMJs) is doubled. Aldicarb-induced potentiation was eliminated by mutations that block processing of proneuropeptides, by mutations inactivating a single proneuropeptide (NLP-12), and by those inactivating an NLP-12 receptor (CKR-2). NLP-12 expression is limited to a single stretch-activated neuron, DVA. Analysis of a YFP-tagged NLP-12 suggests that aldicarb stimulates DVA secretion of NLP-12. Mutations disrupting the DVA mechanoreceptor (TRP-4) decreased aldicarb-induced NLP-12 secretion and blocked aldicarb-induced synaptic potentiation. Mutants lacking NLP-12 or CKR-2 have decreased locomotion rates. Collectively, these results suggest that NLP-12 mediates a mechanosensory feedback loop that couples muscle contraction to changes in presynaptic release, thereby providing a mechanism for proprioceptive control of locomotion.

AB Cell surface Ig superfamily proteins (IgSF) have been implicated in several aspects of neuron development and function. Here, we describe the function of a Caenorhabditis elegans IgSF protein, RIG-3. Mutants lacking RIG-3 have an exaggerated paralytic response to a cholinesterase inhibitor, aldicarb. Although RIG-3 is expressed in motor neurons, heightened drug responsiveness was caused by an aldicarb-induced increase in muscle ACR-16 acetylcholine receptor (AChR) abundance, and a corresponding potentiation of postsynaptic responses at neuromuscular junctions. Mutants lacking RIG-3 also had defects in the anteroposterior polarity of the ALM mechanosensory neurons. The effects of RIG-3 on synaptic transmission and ALM polarity were both mediated by changes in Wnt signaling, and in particular by inhibiting CAM-1, a Ror-type receptor tyrosine kinase that binds Wnt ligands. These results identify RIG-3 as a regulator of Wnt signaling, and suggest that RIG-3 has an anti-plasticity function that prevents activity-induced changes in postsynaptic receptor fields.

AB BACKGROUND
It is not known whether short-term androgen-deprivation therapy (ADT) before and during radiotherapy improves cancer control and overall survival among patients with early, localized prostate adenocarcinoma.
METHODS
From 1994 through 2001, we randomly assigned 1979 eligible patients with stage T1b, T1c, T2a, or T2b prostate adenocarcinoma and a prostate-specific antigen (PSA) level of 20 ng per milliliter or less to radiotherapy alone (992 patients) or radiotherapy with 4 months of total androgen suppression starting 2 months before radiotherapy (radiotherapy plus short-term ADT, 987 patients). The primary end point was overall survival. Secondary end points included disease-specific mortality, distant metastases, biochemical failure (an increasing level of PSA), and the rate of positive findings on repeat prostate biopsy at 2 years.
RESULTS
The median follow-up period was 9.1 years. The 10-year rate of overall survival was 62% among patients receiving radiotherapy plus short-term ADT (the combined-therapy group), as compared with 57% among patients receiving radiotherapy alone (hazard ratio for death with radiotherapy alone, 1.17; P = 0.03). The addition of short-term ADT was associated with a decrease in the 10-year disease-specific mortality from 8% to 4% (hazard ratio for radiotherapy alone, 1.87; P = 0.001). Biochemical failure, distant metastases, and the rate of positive findings on repeat prostate biopsy at 2 years were significantly improved with radiotherapy plus short-term ADT. Acute and late radiation-induced toxic effects were similar in the two groups. The incidence of grade 3 or higher hormone-related toxic effects was less than 5%. Reanalysis according to risk showed reductions in overall and disease-specific mortality primarily among intermediate-risk patients, with no significant reductions among low-risk patients.
CONCLUSIONS
Among patients with stage T1b, T1c, T2a, or T2b prostate adenocarcinoma and a PSA level of 20 ng per milliliter or less, the use of short-term ADT for 4 months before and during radiotherapy was associated with significantly decreased disease-specific mortality and increased overall survival. According to post hoc risk analysis, the benefit was mainly seen in intermediate-risk, but not low-risk, men.

TI Active Albuterol or Placebo, Sham Acupuncture, or No Intervention in
Asthma
SO NEW ENGLAND JOURNAL OF MEDICINE
LA English
DT Article
ID AIRWAY-OBSTRUCTION; CONTROLLED-TRIALS; FATAL ASTHMA; PERCEPTION;
SUGGESTION; DYSPNEA
AB BACKGROUND
In prospective experimental studies in patients with asthma, it is difficult to determine whether responses to placebo differ from the natural course of physiological changes that occur without any intervention. We compared the effects of a bronchodilator, two placebo interventions, and no intervention on outcomes in patients with asthma.
METHODS
In a double-blind, crossover pilot study, we randomly assigned 46 patients with asthma to active treatment with an albuterol inhaler, a placebo inhaler, sham acupuncture, or no intervention. Using a block design, we administered one each of these four interventions in random order during four sequential visits (3 to 7 days apart); this procedure was repeated in two more blocks of visits (for a total of 12 visits by each patient). At each visit, spirometry was performed repeatedly over a period of 2 hours. Maximum forced expiratory volume in 1 second (FEV(1)) was measured, and patients' self-reported improvement ratings were recorded.
RESULTS
Among the 39 patients who completed the study, albuterol resulted in a 20% increase in FEV1, as compared with approximately 7% with each of the other three interventions (P<0.001). However, patients' reports of improvement after the intervention did not differ significantly for the albuterol inhaler (50% improvement), placebo inhaler (45%), or sham acupuncture (46%), but the subjective improvement with all three of these interventions was significantly greater than that with the no-intervention control (21%) (P<0.001).
CONCLUSIONS
Although albuterol, but not the two placebo interventions, improved FEV1 in these patients with asthma, albuterol provided no incremental benefit with respect to the self-reported outcomes. Placebo effects can be clinically meaningful and can rival the effects of active medication in patients with asthma. However, from a clinical-management and research-design perspective, patient self-reports can be unreliable. An assessment of untreated responses in asthma may be essential in evaluating patient-reported outcomes. (Funded by the National Center for Complementary and Alternative Medicine.)

AB Malignant transformation, driven by gain-of-function mutations in oncogenes and loss-of-function mutations in tumour suppressor genes, results in cell deregulation that is frequently associated with enhanced cellular stress (for example, oxidative, replicative, metabolic and proteotoxic stress, and DNA damage)(1). Adaptation to this stress phenotype is required for cancer cells to survive, and consequently cancer cells may become dependent upon non-oncogenes that do not ordinarily perform such a vital function in normal cells. Thus, targeting these non-oncogene dependencies in the context of a transformed genotype may result in a synthetic lethal interaction and the selective death of cancer cells(2). Here we used a cell-based small-molecule screening and quantitative proteomics approach that resulted in the unbiased identification of a small molecule that selectively kills cancer cells but not normal cells. Piperlongumine increases the level of reactive oxygen species (ROS) and apoptotic cell death in both cancer cells and normal cells engineered to have a cancer genotype, irrespective of p53 status, but it has little effect on either rapidly or slowly dividing primary normal cells. Significant antitumour effects are observed in piperlongumine-treated mouse xenograft tumour models, with no apparent toxicity in normal mice. Moreover, piperlongumine potently inhibits the growth of spontaneously formed malignant breast tumours and their associated metastases in mice. Our results demonstrate the ability of a small molecule to induce apoptosis selectively in cells that have a cancer genotype, by targeting a non-oncogene co-dependency acquired through the expression of the cancer genotype in response to transformation-induced oxidative stress(3-5).

AB The retinal ganglion cells (RGCs) have diverse morphology and physiology. Although some studies show that correlations between morphological properties and physiological properties exist in cat RGCs, these properties are much less distinct and their correlations are unknown in mouse RGCs. In this study, using three-dimensional digital neuron reconstruction, we systematically analyzed twelve morphological parameters of mouse RGCs as they developed in the first four postnatal weeks. The development of these parameters fell into three different patterns and suggested that contact from bipolar cells and eye opening might play important roles in RGC morphological development. Although there has been a general impression that the morphological parameters are not independent, such as RGCs with larger dendritic fields usually have longer but sparser dendrites, there was not systematic study and statistical analysis proving it. We used Pearson's correlation coefficients to determine the relationship among these morphological parameters and demonstrated that many morphological parameters showed high statistical correlation. In the same cells we also measured seven physiological parameters using whole-cell patch-clamp recording, focusing on intrinsic excitability. We previously reported the increase in intrinsic excitability in mouse RGCs during early postnatal development. Here we showed that strong correlations also existed among many physiological parameters that measure the intrinsic excitability. However, Pearson's correlation coefficient revealed very limited correlation across morphological and physiological parameters. In addition, principle component analysis failed to separate RGCs into clusters using combined morphological and physiological parameters. Therefore, despite strong correlations within the morphological parameters and within the physiological parameters, postnatal mouse RGCs had only limited correlation between morphology and physiology. This may be due to developmental immaturity, or to selection of parameters.

TI Medial Temporal Lobe Damage Causes Deficits in Episodic Memory and
Episodic Future Thinking Not Attributable to Deficits in Narrative

AB The medial temporal lobe (MTL) makes critical contributions to episodic memory, but its contributions to episodic future thinking remain a matter of debate. By one view, imagining future events relies on MTL mechanisms that also support memory for past events. Alternatively, it has recently been suggested that future thinking is independent of MTL-mediated processes and can be supported by regions outside the MTL. The current study investigated the nature and necessity of MTL involvement in imagining the future and tested the novel hypothesis that the MTL contributes to future thinking by supporting online binding processes related to narrative construction. Human amnesic patients with well characterized MTL damage and healthy controls constructed narratives about (1) future events, (2) past events, and (3) visually presented pictures. While all three tasks place similar demands on narrative construction, only the past and future conditions require memory/future thinking to mentally generate relevant narrative information. Patients produced impoverished descriptions of both past and future events but were unimpaired at producing detailed picture narratives. In addition, future-thinking performance positively correlated with episodic memory performance but did not correlate with picture narrative performance. Finally, future-thinking impairments were present when MTL lesions were restricted to the hippocampus and did not depend on the presence of neural damage outside the MTL. These results indicate that the ability to generate and maintain a detailed narrative is preserved in amnesia and suggest that a common MTL mechanism supports both episodic memory and episodic future thinking.

AB Context Knowledge of family cancer history is important for assessing cancer risk and guiding screening recommendations.
Objective To quantify how often throughout adulthood clinically significant changes occur in cancer family history that would result in recommendations for earlier or intense screening.
Design and Setting Descriptive study examining baseline and follow-up family history data from participants in the Cancer Genetics Network (CGN), a US national population-based cancer registry, between 1999 and 2009.
Participants Adults with a personal history, family history, or both of cancer enrolled in the CGN through population-based cancer registries. Retrospective colorectal, breast, and prostate cancer screening-specific analyses included 9861, 2547, and 1817 participants, respectively; prospective analyses included 1533, 617, and 163 participants, respectively. Median follow-up was 8 years (range, 0-11 years). Screening-specific analyses excluded participants with the cancer of interest.
Main Outcome Measures Percentage of individuals with clinically significant family histories and rate of change over 2 periods: (1) retrospectively, from birth until CGN enrollment and (2) prospectively, from enrollment to last follow-up.
Results Retrospective analysis revealed that the percentages of participants who met criteria for high-risk screening based on family history at ages 30 and 50 years, respectively, were as follows: for colorectal cancer, 2.1% (95% confidence interval [CI], 1.8%-2.4%) and 7.1%(95% CI, 6.5%-7.6%); for breast cancer, 7.2%(95% CI, 6.1%-8.4%) and 11.4% (95% CI, 10.0%-12.8%); and for prostate cancer, 0.9%(95% CI, 0.5%-1.4%) and 2.0% (95% CI, 1.4%-2.7%). In prospective analysis, the numbers of participants who newly met criteria for high-risk screening based on family history per 100 persons followed up for 20 years were 2 (95% CI, 0-7) for colorectal cancer, 6 (95% CI, 2-13) for breast cancer, and 8 (95% CI, 3-16) for prostate cancer. The rate of change in cancer family history was similar for colorectal and breast cancer between the 2 analyses.
Conclusion Clinically relevant family history of colorectal, breast, and prostate cancer that would result in recommendations for earlier or intense cancer screening increases between ages 30 and 50 years, although the absolute rate is low for prostate cancer. JAMA. 2011; 306(2): 172-178

AB Mislocated enzymatic activity of DOT1L has been proposed as a driver of leukemogenesis in mixed lineage leukemia (MLL). The characterization of EPZ004777, a potent, selective inhibitor of DOT1L is reported. Treatment of MLL cells with the compound selectively inhibits H3K79 methylation and blocks expression of leukemogenic genes. Exposure of leukemic cells to EPZ004777 results in selective killing of those cells bearing the MLL gene translocation, with little effect on non-MLL-translocated cells. Finally, in vivo administration of EPZ004777 leads to extension of survival in a mouse MLL xenograft model. These results provide compelling support for DOT1L inhibition as a basis for targeted therapeutics against MLL.

AB The histone 3 lysine 79 (H3K79) methyltransferase Dot1l has been implicated in the development of leukemias bearing translocations of the Mixed Lineage Leukemia (MLL) gene. We identified the MLL-fusion targets in an MLL-AF9 leukemia model, and conducted epigenetic profiling for H3K79me2, H3K4me3, H3K27me3, and H3K36me3 in hematopoietic progenitor and leukemia stem cells (LSCs). We found abnormal profiles only for H3K79me2 on MLL-AF9 fusion target loci in LSCs. Inactivation of Dot1l led to downregulation of direct MLL-AF9 targets and an MLL translocation-associated gene expression signature, whereas global gene expression remained largely unaffected. Suppression of MLL translocation-associated gene expression corresponded with dependence of MLL-AF9 leukemia on Dot1l in vivo. These data point to DOT1L as a potential therapeutic target in MLL-rearranged leukemia.

AB Clinical and genomic evidence suggests that the metastatic potential of a primary tumor may be dictated by prometastatic events that have additional oncogenic capability. To test this "deterministic" hypothesis, we adopted a comparative oncogenomics-guided function-based strategy involving: (1) comparison of global transcriptomes of two genetically engineered mouse models with contrasting metastatic potential, (2) genomic and transcriptomic profiles of human melanoma, (3) functional genetic screen for enhancers of cell invasion, and (4) evidence of expression selection in human melanoma tissues. This integrated effort identified six genes that are potently proinvasive and oncogenic. Furthermore, we show that one such gene, ACP5, confers spontaneous metastasis in vivo, engages a key pathway governing metastasis, and is prognostic in human primary melanomas.

AB Endocrine therapies for breast cancer that target the estrogen receptor (ER) are ineffective in the 25%-30% of cases that are ER negative (ER-). Androgen receptor (AR) is expressed in 60%-70% of breast tumors, independent of ER status. How androgens and AR regulate breast cancer growth remains largely unknown. We find that AR is enriched in ER- breast tumors that overexpress HER2. Through analysis of the AR cistrome and androgen-regulated gene expression in ER-/HER2+ breast cancers we find that AR mediates ligand-dependent activation of Wnt and HER2 signaling pathways through direct transcriptional induction of WNT7B and HER3. Specific targeting of AR, Wnt or HER2 signaling impairs androgen-stimulated tumor cell growth suggesting potential therapeutic approaches for ER-/HER2+ breast cancers.

AB Background-Essential hypertension has been recognized as a disease resulting from a combination of environmental and genetic factors. Recent studies demonstrated that microRNAs (miRNAs) are involved in cardiac hypertrophy and heart failure. However, little is known about the roles of miRNAs in essential hypertension.
Methods and Results-Using microarray-based miRNA expression profiling, we compared the miRNA expressions in plasma samples from 13 hypertensive patients and 5 healthy control subjects. Twenty-seven miRNAs were found to be differentially expressed. The expressions of selected miRNAs (miR-296-5p, let-7e, and a human cytomegalovirus [HCMV]-encoded miRNA, hcmv-miR-UL112) were validated independently in plasma samples from 24 hypertensive patients and 22 control subjects. The absolute expression levels of hcmv-miR-UL112, miR-296-5p, and let-7e were further determined in 127 patients and 67 control subjects (fold changes are 2.5, 0.5, and 1.7 respectively; all P < 0.0001). Additionally, we demonstrated that interferon regulatory factor 1 is a direct target of hcmv-miR-UL112. Increased HCMV seropositivity and quantitative titers were found in the hypertension group compared with the control group (52.7% versus 30.9%, P = 0.0005; 1870 versus 54 copies per 1 mL plasma, P < 0.0001). Seropositivity, log-transformed copies of HCMV, and hcmv-miR-UL112 were independently associated with an increased risk of hypertension (odds ratio, 2.48; 95% confidence interval, 1.48 to 4.15; P = 0.0005; odds ratio, 1.97; 95% confidence interval, 1.58 to 2.46; P < 0.0001; and odds ratio, 2.55; 95% confidence interval, 1.98 to 3.27; P < 0.0001, respectively).
Conclusions-We report for the first time a circulating miRNA profile for hypertensive patients and demonstrate a novel link between HCMV infection and essential hypertension. These findings may reveal important insights into the pathogenesis of essential hypertension.

AB Primary open-angle glaucoma (POAG) is the most common form of glaucoma and one of the leading causes of vision loss worldwide. The genetic etiology of POAG is complex and poorly understood. The purpose of this work is to identify genomic regions of interest linked to POAG. This study is the largest genetic linkage study of POAG performed to date: genomic DNA samples from 786 subjects (538 Caucasian ancestry, 248 African ancestry) were genotyped using either the Illumina GoldenGate Linkage 4 Panel or the Illumina Infinium Human Linkage-12 Panel. A total of 5233 SNPs was analyzed in 134 multiplex POAG families (89 Caucasian ancestry, 45 African ancestry). Parametric and non-parametric linkage analyses were performed on the overall dataset and within race-specific datasets (Caucasian ancestry and African ancestry). Ordered subset analysis was used to stratify the data on the basis of age of glaucoma diagnosis. Novel linkage regions were identified on chromosomes 1 and 20, and two previously described loci-GLC1D on chromosome 8 and GLC1I on chromosome 15-were replicated. These data will prove valuable in the context of interpreting results from genome-wide association studies for POAG.

AB Background: Little is known about the long-term impact of the killing of a parent in childhood or adolescence during war on distress and disability in young adulthood. This study assessed current prevalence rates of mental disorders and levels of dysfunction among young adults who had lost their father due to war-related violence in childhood or adolescence.
Methods: 179 bereaved young adults and 175 non-bereaved young adults were interviewed a decade after experiencing the war in Kosovo. Prevalence rates of Major Depressive Episode (MDE), anxiety, and substance use disorders, and current suicide risk were assessed using the Mini-International Neuropsychiatric Interview. The syndrome of Prolonged Grief Disorder (PGD) was assessed with the Prolonged Grief Disorder Interview (PG-13). Somatic symptoms were measured with the Patient Health Questionnaire. General health distress was assessed with the General Health Questionnaire.
Findings: Bereaved participants were significantly more likely to suffer from either MDE or any anxiety disorder than non-bereaved participants (58.7% vs. 40%). Among bereaved participants, 39.7% met criteria for Post-Traumatic Stress Disorder, 34.6% for PGD, and 22.3% for MDE. Bereaved participants with PGD were more likely to suffer from MDE, any anxiety disorder, or current suicide risk than bereaved participants without PGD. Furthermore, these participants reported significantly greater physical distress than bereaved participants without PGD.
Conclusion: War-related loss during middle childhood and adolescence presents significant risk for adverse mental health and dysfunction in young adulthood in addition to exposure to other war-related traumatic events. Furthermore, the syndrome of PGD can help to identify those with the greatest degree of distress and dysfunction.

TI An Empirical Analysis of Overlap Publication in Chinese Language and
English Research Manuscripts
SO PLOS ONE
LA English
DT Article
ID DUPLICATE PUBLICATION; ERROR MANAGEMENT; CITATIONS; JOURNALS; ICEBERG;
TIP
AB Background: There are a number of sound justifications for publishing nearly identical information in Chinese and English medical journals, assuming several conditions are met. Although overlap publication is perceived as undesirable and ethically questionable in Europe and North America, it may serve an important function in some regions where English is not the native tongue. There is no empirical data on the nature and degree of overlap publication in English and Chinese language journals.
Methods/Principal Findings: A random sample of 100 English manuscripts from Chinese institutions was selected from PubMed. Key words and institutions were searched in the China National Knowledge Infrastructure, a comprehensive Chinese language research database. Unacknowledged overlap was a priori defined according to International Committee of Medical Journal Editor (ICMJE) guidelines following examination by two individuals. 19% (95% CI 11-27) of English manuscripts from Chinese institutions were found to have substantial overlap with Chinese published work based on full text examination. None of the manuscripts met all of the criteria established by the ICMJE for an acknowledged overlap publication. Individual-level, journal-level, and institutional factors seem to influence overlap publication. Manuscripts associated with an institution outside of China and with more than one institution were significantly less likely to have substantial overlap (p<0.05).
Conclusions/Significance: Overlap publication was common in this context, but instances of standard ICMJE notations to acknowledge this practice were rare. This research did not cite the identified overlap manuscripts with the hope that these empirical data will inform journal policy changes and structural initiatives to promote clearer policies and manuscripts.

AB Objectives This study was conducted to evaluate mineral metabolism markers as potential risk factors for calcific aortic valve disease.
Background Mineral metabolism disturbances are common among older people and may contribute to cardiac valvular calcification. Associations of serum mineral metabolism markers with cardiac valvular calcification have not been evaluated in a well-characterized general population of older adults.
Methods We measured serum levels of phosphate, calcium, parathyroid hormone, and 25-hydroxyvitamin D in 1,938 Cardiovascular Health Study participants who were free of clinical cardiovascular disease and who underwent echo-cardiographic measurements of aortic valve sclerosis (AVS), mitral annular calcification (MAC), and aortic annular calcification (AAC). We used logistic regression models to estimate associations of mineral metabolism markers with AVS, MAC, and AAC after adjustment for relevant confounding variables, including kidney function.
Results The respective prevalences of AVS, MAC, and AAC were 54%, 39%, and 44%. Each 0.5 mg/dl higher serum phosphate concentration was associated with greater adjusted odds of AVS (odds ratio [OR]: 1.17, 95% confidence interval [CI]: 1.04 to 1.31, p = 0.01), MAC (OR: 1.12, 95% CI: 1.00 to 1.26, p = 0.05), and AAC (OR: 1.12, 95% CI: 0.99 to 1.25, p = 0.05). In contrast, serum calcium, parathyroid hormone, and 25-hydroxyvitamin D concentrations were not associated with aortic or mitral calcification.
Conclusions Higher serum phosphate levels within the normal range were associated with valvular and annular calcification in a community-based cohort of older adults. Phosphate may be a novel risk factor for calcific aortic valve disease and warrants further study. (J Am Coll Cardiol 2011;58:291-7) (C) 2011 by the American College of Cardiology Foundation

AB Nuclear factor of activated T cells (NFAT) proteins are Ca(2+)-regulated transcription factors that control gene expression in many cell types. NFAT proteins are heavily phosphorylated and reside in the cytoplasm of resting cells; when cells are stimulated by a rise in intracellular Ca(2+), NFAT proteins are dephosphorylated by the Ca(2+)/calmodulin-dependent phosphatase calcineurin and translocate to the nucleus to activate target gene expression. Here we show that phosphorylated NFAT1 is present in a large cytoplasmic RNA-protein scaffold complex that contains a long intergenic noncoding RNA (lincRNA), NRON [noncoding (RNA) repressor of NFAT]; a scaffold protein, IQ motif containing GTPase activating protein (IQGAP); and three NFAT kinases, casein kinase 1, glycogen synthase kinase 3, and dual specificity tyrosine phosphorylation regulated kinase. Combined knockdown of NRON and IQGAP1 increased NFAT dephosphorylation and nuclear import exclusively after stimulation, without affecting the rate of NFAT rephosphorylation and nuclear export; and both NRON-depleted T cells and T cells from IQGAP1-deficient mice showed increased production of NFAT-dependent cytokines. Our results provide evidence that a complex of lincRNA and protein forms a scaffold for a latent transcription factor and its regulatory kinases, and support an emerging consensus that lincRNAs that bind transcriptional regulators have a similar scaffold function.

AB Neuronal development is the result of a multitude of neural migrations, which require extensive cell-cell communication. These processes are modulated by extracellular matrix components, such as heparan sulfate (HS) polysaccharides. HS is molecularly complex as a result of nonrandom modifications of the sugar moieties, including sulfations in specific positions. We report here mutations in HS 6-O-sulfotransferase 1 (HS6ST1) in families with idiopathic hypogonadotropic hypogonadism (IHH). IHH manifests as incomplete or absent puberty and infertility as a result of defects in gonadotropin-releasing hormone neuron development or function. IHH-associated HS6ST1 mutations display reduced activity in vitro and in vivo, suggesting that HS6ST1 and the complex modifications of extracellular sugars are critical for normal development in humans. Genetic experiments in Caenorhabditis elegans reveal that HS cell-specifically regulates neural branching in vivo in concert with other IHH-associated genes, including kal-1, the FGF receptor, and FGF. These findings are consistent with a model in which KAL1 can act as a modulatory coligand with FGF to activate the FGF receptor in an HS-dependent manner.

AB Cellular immune control of HIV is mediated, in part, by induction of single amino acid mutations that reduce viral fitness, but compensatory mutations limit this effect. Here, we sought to determine if higher order constraints on viral evolution exist, because some coordinately linked combinations of mutations may hurt viability. Immune targeting of multiple sites in such a multidimensionally conserved region might render the virus particularly vulnerable, because viable escape pathways would be greatly restricted. We analyzed available HIV sequences using a method from physics to reveal distinct groups of amino acids whose mutations are collectively coordinated ("HIV sectors"). From the standpoint of mutations at individual sites, one such group in Gag is as conserved as other collectively coevolving groups of sites in Gag. However, it exhibits higher order conservation indicating constraints on the viability of viral strains with multiple mutations. Mapping amino acids from this group onto protein structures shows that combined mutations likely destabilize multiprotein structural interactions critical for viral function. Persons who durably control HIV without medications preferentially target the sector in Gag predicted to be most vulnerable. By sequencing circulating viruses from these individuals, we find that individual mutations occur with similar frequency in this sector as in other targeted Gag sectors. However, multiple mutations within this sector are very rare, indicating previously unrecognized multidimensional constraints on HIV evolution. Targeting such regions with higher order evolutionary constraints provides a novel approach to immunogen design for a vaccine against HIV and other rapidly mutating viruses.

AB Antivascular agents have become a standard of treatment for many malignancies. However, most of them target the VEGF pathway and lead to refractoriness. To improve the diversity of options for antivascular therapy, we applied a high-throughput screen for small molecules targeting cell adhesion. We then assayed the resulting antiadhesion hits in a transgenic zebrafish line with endothelial expression of EGFP (Tg(fli1:EGFP)(y1)) to identify nontoxic molecules with antivascular activity selective to neovasculature. This screen identified dehydro-alpha-lapachone (DAL), a natural plant product. We found that DAL inhibits vessel regeneration, interferes with vessel anastomosis, and limits plexus formation in zebrafish. Furthermore, DAL induces vascular pruning and growth delay in orthotopic mammary tumors in mice. We show that DAL targets cell adhesion by promoting ubiquitination of the Rho-GTPase Rac1, which is frequently up-regulated in many different cancers.

QUALITY; RISK; GUIDELINES
AB Background: High-quality systems have adopted a comprehensive approach to preventive care instead of diagnosis or procedure driven care. The current emphasis on prescribing medications to prevent complications of coronary artery disease (CAD) at discharge following an acute coronary syndrome (ACS) may exclude high-risk patients who are hospitalized with conditions other than ACS.
Methods: Among a sample of patients with CAD treated at Veterans Affairs medical centers between January, 2005 and November, 2006, we investigated whether recent non-ACS hospitalization was associated with prescriptions of preventive medications as compared with patients recently hospitalized with ACS.
Results: Of 13,211 patients with CAD, 58% received aspirin, 70% beta-blocker, 60% angiotensin-converting enzyme inhibitor (ACE-I) or angiotensin II receptor blocker (ARB), and 65% lipid-lowering therapy. Twenty-five percent of eligible patients were receiving all four medications. Having been hospitalized for a non-ACS event in the prior 6 months did not substantially affect the adjusted proportion on preventive medications. In contrast, among patients hospitalized for ACS in the prior 6 months, the adjusted proportion prescribed aspirin was 21% higher (p < 0.001), beta-blocker was 14% higher (p < 0.001), ACE-I or ARB was 9% higher (p < 0.001), lipid therapy was 12% higher (p < 0.001), and prescribed all four medications was 18% higher (p < 0.001) than among patients hospitalized for ACS more than 2 years earlier.
Conclusions: Being hospitalized for a non-ACS condition did not appear to influence preventive medication use among patients with CAD and represents a missed opportunity to improve patient care. The same protocols employed to improve use of preventive medications in patients discharged for ACS might be extended to CAD patients discharged for other conditions as well.

ID HEALTH; CHI; SF-36
AB Background: Qigong, similar to Tai Chi Chuan, is beneficial to health. In Taiwan, Waitankung, a type of Qigong, is as popular as Tai Chi Chuan. This population-based comparison study compares the health-related quality of life between people practicing Waitankung and their comparable community residents.
Methods: A total of 165 individuals practicing Waitankung were matched by age and sex with 660 general individuals for comparison. Information about health-related quality of life, measured by the SF-36, and other basic and health conditions was obtained from the questionnaires. This study used the linear mixed-effect regression model to examine the association between health-related quality of life and the practice of Waitankung.
Results: Compared with either sedentary individuals or individuals practicing other types of exercise, the Waitankung group scored higher for eight and five out of ten SF-36 components, respectively. The Waitankung group scored better in general health, vitality, and physical component summary compared to individuals participating in other types of exercise, even when considering the energy expended by exercise.
Conclusion: The results suggest that Waitankung exercising is significantly associated with health-related quality of life. Waitankung may serve as an exercise choice for middle-aged and older people to improve overall quality of life.

AB Deregulation of SHP2 is associated with malignant diseases as well as developmental disorders. Although SHP2 is required for full activation of RAS signaling, other potential roles in cell physiology have not been elucidated. Here we show that SHP2 dephosphorylates parafibromin/Cdc73, a core component of the RNA polymerase II-associated factor (PAF) complex. Parafibromin is known to act as a tumor suppressor that inhibits cyclin D1 and c-myc by recruiting SUV39H1 histone methyltransferase. However, parafibromin can also act in the opposing direction by binding beta-catenin, thereby activating promitogenic/oncogenic Wnt signaling. We found that, on tyrosine dephosphorylation by SHP2, parafibromin acquires the ability to stably bind beta-catenin. The parafibromin/beta-catenin interaction overrides parafibromin/SUV39H1-mediated transrepression and induces expression of Wnt target genes, including cyclin D1 and c-myc. Hence, SHP2 governs the opposing functions of parafibromin, deregulation of which may cause the development of tumors or developmental malformations.

AB Background: Genetic variation in IL28B and other factors are associated with sustained virological response (SVR) after pegylated-interferon/ribavirin treatment for chronic hepatitis C (CHC). Using data from the HALT-C Trial, we developed a model to predict a patient's probability of SVR based on IL28B genotype and clinical variables.
Methods: HALT-C enrolled patients with advanced CHC who had failed previous interferon-based treatment. Subjects were re-treated with pegylated-interferon/ribavirin during trial lead-in. We used step-wise logistic regression to calculate adjusted odds ratios (aOR) and create the predictive model. Leave-one-out cross-validation was used to predict a priori probabilities of SVR and determine area under the receiver operator characteristics curve (AUC).
Results: Among 646 HCV genotype 1-infected European American patients, 14.2% achieved SVR. IL28B rs12979860-CC genotype was the strongest predictor of SVR (aOR, 7.56; p <.0001); the model also included HCV RNA (log10 IU/ml), AST:ALT ratio, Ishak fibrosis score and prior ribavirin treatment. For this model AUC was 78.5%, compared to 73.0% for a model restricted to the four clinical predictors and 60.0% for a model restricted to IL28B genotype (p < 0.001). Subjects with a predicted probability of SVR < 10% had an observed SVR rate of 3.8%; subjects with a predicted probability > 10% (43.3% of subjects) had an SVR rate of 27.9% and accounted for 84.8% of subjects actually achieving SVR. To verify that consideration of both IL28B genotype and clinical variables is required for treatment decisions, we calculated AUC values from published data for the IDEAL Study.
Conclusion: A clinical prediction model based on IL28B genotype and clinical variables can yield useful individualized predictions of the probability of treatment success that could increase SVR rates and decrease the frequency of futile treatment among patients with CHC.

TI [PSI+] Maintenance Is Dependent on the Composition, Not Primary

AB [PSI+], the prion form of the yeast Sup35 protein, results from the structural conversion of Sup35 from a soluble form into an infectious amyloid form. The infectivity of prions is thought to result from chaperone-dependent fiber cleavage that breaks large prion fibers into smaller, inheritable propagons. Like the mammalian prion protein PrP, Sup35 contains an oligopeptide repeat domain. Deletion analysis indicates that the oligopeptide repeat domain is critical for [PSI+] propagation, while a distinct region of the prion domain is responsible for prion nucleation. The PrP oligopeptide repeat domain can substitute for the Sup35 oligopeptide repeat domain in supporting [PSI+] propagation, suggesting a common role for repeats in supporting prion maintenance. However, randomizing the order of the amino acids in the Sup35 prion domain does not block prion formation or propagation, suggesting that amino acid composition is the primary determinant of Sup35's prion propensity. Thus, it is unclear what role the oligopeptide repeats play in [PSI+] propagation: the repeats could simply act as a non-specific spacer separating the prion nucleation domain from the rest of the protein; the repeats could contain specific compositional elements that promote prion propagation; or the repeats, while not essential for prion propagation, might explain some unique features of [PSI+]. Here, we test these three hypotheses and show that the ability of the Sup35 and PrP repeats to support [PSI+] propagation stems from their amino acid composition, not their primary sequences. Furthermore, we demonstrate that compositional requirements for the repeat domain are distinct from those of the nucleation domain, indicating that prion nucleation and propagation are driven by distinct compositional features.

AB A change in coreceptor preference from CCR5 to CXCR4 towards the end stage disease in some HIV-1 infected individuals has been well documented, but the reasons and mechanisms for this tropism switch remain elusive. It has been suggested that envelope structural constraints in accommodating amino acid changes required for CXCR4 usage is an obstacle to tropism switch, limiting the rate and pathways available for HIV-1 coreceptor switching. The present study was initiated in two R5 SHIV(SF162P3N)-infected rapid progressor macaques with coreceptor switch to test the hypothesis that an early step in the evolution of tropism switch is the adoption of a less constrained and more "open" envelope conformation for better CD4 usage, allowing greater structural flexibility to accommodate further mutational changes that confer CXCR4 utilization. We show that, prior to the time of coreceptor switch, R5 viruses in both macaques evolved to become increasingly sCD4-sensitive, suggestive of enhanced exposure of the CD4 binding site and an "open" envelope conformation, and this correlated with better gp120 binding to CD4 and with more efficient infection of CD4(low) cells such as primary macrophages. Moreover, significant changes in neutralization sensitivity to agents and antibodies directed against functional domains of gp120 and gp41 were seen for R5 viruses close to the time of X4 emergence, consistent with global changes in envelope configuration and structural plasticity. These observations in a simian model of R5-to-X4 evolution provide a mechanistic basis for the HIV-1 coreceptor switch.

AB Parkinson's disease (PD), an adult neurodegenerative disorder, has been clinically linked to the lysosomal storage disorder Gaucher disease (GD), but the mechanistic connection is not known. Here, we show that functional loss of GD-linked glucocerebrosidase (GCase) in primary cultures or human iPS neurons compromises lysosomal protein degradation, causes accumulation of alpha-synuclein (alpha-syn), and results in neurotoxicity through aggregation-dependent mechanisms. Glucosylceramide (GlcCer), the GCase substrate, directly influenced amyloid formation of purified alpha-syn by stabilizing soluble oligomeric intermediates. We further demonstrate that alpha-syn inhibits the lysosomal activity of normal GCase in neurons and idiopathic PD brain, suggesting that GCase depletion contributes to the pathogenesis of sporadic synucleinopathies. These findings suggest that the bidirectional effect of alpha-syn and GCase forms a positive feedback loop that may lead to a self-propagating disease. Therefore, improved targeting of GCase to lysosomes may represent a specific therapeutic approach for PD and other synucleinopathies.

AB Malignant gliomas are aggressive brain tumors with limited therapeutic options, and improvements in treatment require a deeper molecular understanding of this disease. As in other cancers, recent studies have identified highly tumorigenic subpopulations within malignant gliomas, known generally as cancer stem cells. Here, we demonstrate that glioma stem cells (GSCs) produce nitric oxide via elevated nitric oxide synthase-2 (NOS2) expression. GSCs depend on NOS2 activity for growth and tumorigenicity, distinguishing them from non-GSCs and normal neural progenitors. Gene expression profiling identified many NOS2-regulated genes, including the cell-cycle inhibitor cell division autoantigen-1 (CDA1). Further, high NOS2 expression correlates with decreased survival in human glioma patients, and NOS2 inhibition slows glioma growth in a murine intracranial model. These data provide insight into how GSCs are mechanistically distinct from their less tumorigenic counterparts and suggest that NOS2 inhibition may be an efficacious approach to treating this devastating disease.

AB The long noncoding Xist RNA inactivates one X chromosome in the female mammal. Current models posit that Xist induces silencing as it spreads along X and recruits Polycomb complexes. However, the mechanisms for Xist loading and spreading are currently unknown. Here, we define the nucleation center for Xist RNA and show that YY1 docks Xist particles onto the X chromosome. YY1 is a "bivalent'' protein, capable of binding both RNA and DNA through different sequence motifs. Xist's exclusive attachment to the inactive X is determined by an epigenetically regulated trio of YY1 sites as well as allelic origin. Specific YY1-to-RNA and YY1-to-DNA contacts are required to load Xist particles onto X. YY1 interacts with Xist RNA through Repeat C. We propose that YY1 acts as adaptor between regulatory RNA and chromatin targets.

TI Increased Lipogenesis and Stearate Accelerate Vascular Calcification in

BETA-CELLS; GENE-EXPRESSION; INDUCED LIPOTOXICITY
AB Vascular calcification is recognized as an independent predictor of cardiovascular mortality, particularly in subjects with chronic kidney disease. However, the pathways by which dysregulation of lipid and mineral metabolism simultaneously occur in this particular population remain unclear. We have shown that activation of the farnesoid X receptor (FXR) blocks mineralization of bovine calcifying vascular cells (CVCs) and in ApoE knock-out mice with 5/6 nephrectomy. In contrast to FXR, this study showed that liver X receptor (LXR) activation by LXR agonists and adenovirus-mediated LXR overexpression by VP16-LXR alpha and VP16-LXR beta accelerated mineralization of CVCs. Conversely, LXR inhibition by dominant negative (DN) forms of LXR alpha and LXR beta reduced calcium content in CVCs. The regulation of mineralization by FXR and LXR agonists was highly correlated with changes in lipid accumulation, fatty acid synthesis, and the expression of sterol regulatory element binding protein-1 (SREBP-1). The rate of lipogenesis in CVCs through the SREBP-1c dependent pathway was reduced by FXR activation, but increased by LXR activation. SREBP-1c overexpression augmented mineralization in CVCs, whereas SREBP-1c DN inhibited alkaline phosphatase activity and mineralization induced by LXR agonists. LXR and SREBP-1c activations increased, whereas FXR activation decreased, saturated and monounsaturated fatty acids derived from lipogenesis. In addition, we found that stearate markedly promoted mineralization of CVCs as compared with other fatty acids. Furthermore, inhibition of either acetyl-CoA carboxylase or acyl-CoA synthetase reduced mineralization of CVCs, whereas inhibition of stearoyl-CoA desaturase induced mineralization. Therefore, a stearate metabolite derived from lipogenesis might be a risk factor for the development of vascular calcification.

AB Background: Latinos in the United States have a higher prevalence of type 2 diabetes than non-Latino whites, even after controlling for adiposity. Decreased adiponectin is associated with insulin resistance and predicts T2DM, and therefore may mediate this ethnic difference. We compared total and high-molecular-weight (HMW) adiponectin in Latino versus white individuals, identified factors associated with adiponectin in each ethnic group, and measured the contribution of adiponectin to ethnic differences in insulin resistance.
Methods: We utilized cross-sectional data from subjects in the Latinos Using Cardio Health Actions to reduce Risk study. Participants were Latino (n = 119) and non-Latino white (n = 60) men and women with hypertension and at least one other risk factor for CVD (age 61 +/- 10 yrs, 49% with T2DM), seen at an integrated community health and hospital system in Denver, Colorado. Total and HMW adiponectin was measured by RIA and ELISA respectively. Fasting glucose and insulin were used to calculate the homeostasis model insulin resistance index (HOMA-IR). Variables independently associated with adiponectin levels were identified by linear regression analyses. Adiponectin's contribution to ethnic differences in insulin resistance was assessed in multivariate linear regression models of Latino ethnicity, with logHOMA-IR as a dependent variable, adjusting for possible confounders including age, gender, adiposity, and renal function.
Results: Mean adiponectin levels were lower in Latino than white patients (beta estimates: -4.5 (-6.4, -2.5), p < 0.001 and -1.6 (-2.7, -0.5), p < 0.005 for total and HMW adiponectin), independent of age, gender, BMI/waist circumference, thiazolidinedione use, diabetes status, and renal function. An expected negative association between adiponectin and waist circumference was seen among women and non- Latino white men, but no relationship between these two variables was observed among Latino men. Ethnic differences in logHOMA- IR were no longer observed after controlling for adiponectin levels.
Conclusions: Among patients with CVD risk, total and HMW adiponectin is lower in Latinos, independent of adiposity and other known regulators of adiponectin. Ethnic differences in adiponectin regulation may exist and future research in this area is warranted. Adiponectin levels accounted for the observed variability in insulin resistance, suggesting a contribution of decreased adiponectin to insulin resistance in Latino populations.

AB CREB-binding protein (CREBBP) is important for the cell-autonomous regulation of hematopoiesis, including the stem cell compartment. In the present study, we show that CREBBP plays an equally pivotal role in microenvironment-mediated regulation of hematopoiesis. We found that the BM microenvironment of Crebbp(+/-) mice was unable to properly maintain the immature stem cell and progenitor cell pools. Instead, it stimulates myeloid differentiation, which progresses into a myeloproliferation phenotype. Alterations in the BM microenvironment resulting from haploinsufficiency of Crebbp included a marked decrease in trabecular bone that was predominantly caused by increased osteoclastogenesis. Although CFU-fibroblast (CFU-F) and total osteoblast numbers were decreased, the bone formation rate was similar to that found in wild-type mice. At the molecular level, we found that the known hematopoietic modulators matrix metallopeptidase-9 (MMP9) and kit ligand (KITL) were decreased with heterozygous levels of Crebbp. Lastly, potentially important regulatory proteins, endothelial cell adhesion molecule 1 (ESAM1) and cadherin 5 (CDH5), were increased on Crebbp(+/-) endothelial cells. Our findings reveal that a full dose of Crebbp is essential in the BM microenvironment to maintain proper hematopoiesis and to prevent excessive myeloproliferation. (Blood. 2011;118(1):69-79)

AB Few large, international series of enteropathy-associated T-cell lymphoma (EATL) have been reported. We studied a cohort of 62 patients with EATL among 1153 patients with peripheral T-cell or natural killer (NK)-cell lymphoma from 22 centers worldwide. The diagnosis was made by a consensus panel of 4 expert hematopathologists using World Health Organization (WHO) criteria. Clinical correlations and survival analyses were performed. EATL comprised 5.4% of all lymphomas in the study and was most common in Europe (9.1%), followed by North America (5.8%) and Asia (1.9%). EATL type 1 was more common (66%) than type 2 (34%), and was especially frequent in Europe (79%). A clinical diagnosis of celiac sprue was made in 32.2% of the patients and was associated with both EATL type 1 and type 2. The median overall survival was only 10 months, and the median failure-free survival was only 6 months. The International Prognostic Index (IPI) was not as good a predictor of survival as the Prognostic Index for Peripheral T-Cell Lymphoma (PIT). Clinical sprue predicted for adverse survival independently of the PIT. Neither EATL subtype nor other biologic parameters accurately predicted survival. Our study confirms the poor prognosis of patients with EATL and the need for improved treatment options. (Blood. 2011;118(1):148-155)

AB Polo-like kinases (PLKs) play an important role in cell cycle progression, checkpoint control and mitosis. The high mitotic index and chromosomal instability of advanced cancers suggest that PLK inhibitors may be an attractive therapeutic option for presently incurable advanced neoplasias with systemic involvement, such as multiple myeloma (MM). We studied the PLK 1, 2, 3 inhibitor BI 2536 and observed potent (IC50,40 nM) and rapid (commitment to cell death,24 hrs) in vitro activity against MM cells in isolation, as well as in vivo activity against a traditional subcutaneous xenograft mousemodel. Tumor cells in MM patients, however, don't exist in isolation, but reside in and interact with the bone microenvironment. Therefore conventional in vitro and in vivo preclinical assays don't take into account how interactions between MM cells and the bone microenvironment can potentially confer drug resistance. To probe this question, we performed tumor cell compartment-specific bioluminescence imaging assays to compare the preclinical anti-MM activity of BI 2536 in vitro in the presence vs. absence of stromal cells or osteoclasts. We observed that the presence of these bone marrow non-malignant cells led to decreased anti-MM activity of BI 2536. We further validated these results in an orthotopic in vivo mouse model of diffuse MM bone lesions where tumor cells interact with non-malignant cells of the bone microenvironment. We again observed that BI 2536 had decreased activity in this in vivo model of tumor-bone microenvironment interactions highlighting that, despite BI 2536's promising activity in conventional assays, its lack of activity in microenvironmental models raises concerns for its clinical development for MM. More broadly, preclinical drug testing in the absence of relevant tumor microenvironment interactions may overestimate potential clinical activity, thus explaining at least in part the gap between preclinical vs. clinical efficacy in MM and other cancers.

TI Effect of Nesiritide in Patients with Acute Decompensated Heart Failure

HOSPITALIZED-PATIENTS; OUTCOMES; POPULATION; DIURETICS; RISK
AB Background
Nesiritide is approved in the United States for early relief of dyspnea in patients with acute heart failure. Previous meta-analyses have raised questions regarding renal toxicity and the mortality associated with this agent.
Methods
We randomly assigned 7141 patients who were hospitalized with acute heart failure to receive either nesiritide or placebo for 24 to 168 hours in addition to standard care. Coprimary end points were the change in dyspnea at 6 and 24 hours, as measured on a 7-point Likert scale, and the composite end point of rehospitalization for heart failure or death within 30 days.
Results
Patients randomly assigned to nesiritide, as compared with those assigned to placebo, more frequently reported markedly or moderately improved dyspnea at 6 hours (44.5% vs. 42.1%, P = 0.03) and 24 hours (68.2% vs. 66.1%, P = 0.007), but the prespecified level for significance (P = 0.005 for both assessments or Pd <= 0.0025 for either) was not met. The rate of rehospitalization for heart failure or death from any cause within 30 days was 9.4% in the nesiritide group versus 10.1% in the placebo group (absolute difference, -0.7 percentage points; 95% confidence interval [CI], -2.1 to 0.7; P = 0.31). There were no significant differences in rates of death from any cause at 30 days (3.6% with nesiritide vs. 4.0% with placebo; absolute difference, -0.4 percentage points; 95% CI, -1.3 to 0.5) or rates of worsening renal function, defined by more than a 25% decrease in the estimated glomerular filtration rate (31.4% vs. 29.5%; odds ratio, 1.09; 95% CI, 0.98 to 1.21; P = 0.11).
Conclusions
Nesiritide was not associated with an increase or a decrease in the rate of death and rehospitalization and had a small, nonsignificant effect on dyspnea when used in combination with other therapies. It was not associated with a worsening of renal function, but it was associated with an increase in rates of hypotension. On the basis of these results, nesiritide cannot be recommended for routine use in the broad population of patients with acute heart failure.

TI Uncertainties in planned dose due to the limited voxel size of the
planning CT when treating lung tumors with proton therapy
SO PHYSICS IN MEDICINE AND BIOLOGY
LA English
DT Article
ID CALCULATION RESOLUTION; BEAM THERAPY; BRAGG PEAK; MODEL; DISTRIBUTIONS;
ACCURACY; VOLUME
AB Dose calculation for lung tumors can be challenging due to the low density and the fine structure of the geometry. The latter is not fully considered in the CT image resolution used in treatment planning causing the prediction of a more homogeneous tissue distribution. In proton therapy, this could result in predicting an unrealistically sharp distal dose falloff, i.e. an underestimation of the distal dose falloff degradation. The goal of this work was the quantification of such effects. Two computational phantoms resembling a two-dimensional heterogeneous random lung geometry and a swine lung were considered applying a variety of voxel sizes for dose calculation. Monte Carlo simulations were used to compare the dose distributions predicted with the voxel size typically used for the treatment planning procedure with those expected to be delivered using the finest resolution. The results show, for example, distal falloff position differences of up to 4 mm between planned and expected dose at the 90% level for the heterogeneous random lung (assuming treatment plan on a 2 x 2 x 2.5 mm(3) grid). For the swine lung, differences of up to 38 mm were seen when airways are present in the beam path when the treatment plan was done on a 0.8 x 0.8 x 2.4 mm(3) grid. The two-dimensional heterogeneous random lung phantom apparently does not describe the impact of the geometry adequately because of the lack of heterogeneities in the axial direction. The differences observed in the swine lung between planned and expected dose are presumably due to the poor axial resolution of the CT images used in clinical routine. In conclusion, when assigning margins for treatment planning for lung cancer, proton range uncertainties due to the heterogeneous lung geometry and CT image resolution need to be considered.

ID MONTE-CARLO; RESIDUAL NUCLEI; DISTRIBUTIONS; THERAPY; PARTICLES; GEANT4;
CODE
AB Monte Carlo (MC) codes are useful tools to simulate the complex processes of proton beam interactions with matter. In proton therapy, nuclear reactions influence the dose distribution. Therefore, the validation of nuclear models adopted in MC codes is a critical requisite for their use in this field. A simple integral test can be performed using a multi-layer Faraday cup (MLFC). This method allows separation of the nuclear and atomic interaction processes, which are responsible for secondary particle emission and the finite primary proton range, respectively. In this work, the propagation of 160 MeV protons stopping in two MLFCs made of polyethylene and copper has been simulated by the FLUKA MC code. The calculations have been performed with and without secondary electron emission and transport, as well as charge sharing in the dielectric layers. Previous results with other codes neglected those two effects. The impact of this approximation has been investigated and found to be relevant only in the proximity of the Bragg peak. Longitudinal charge distributions computed with FLUKA with both approaches have been compared with experimental data from the literature. Moreover, the contribution of different processes to the measurable signal has been addressed. A thorough analysis of the results has demonstrated that the nuclear and electromagnetic models of FLUKA reproduce the two sets of experimental data reasonably well.

ID POSITRON-EMISSION-TOMOGRAPHY; BEAM RANGE VERIFICATION
AB We used a mobile positron emission tomography (PET) scanner positioned within the proton therapy treatment room to study the feasibility of proton range verification with an in-room, stand-alone PET system, and compared with off-line equivalent studies. Two subjects with adenoid cystic carcinoma were enrolled into a pilot study in which in-room PET scans were acquired in list-mode after a routine fractionated treatment session. The list-mode PET data were reconstructed with different time schemes to generate in-room short, in-room long and off-line equivalent (by skipping coincidences from the first 15 min during the list-mode reconstruction) PET images for comparison in activity distribution patterns. A phantom study was followed to evaluate the accuracy of range verification for different reconstruction time schemes quantitatively. The in-room PET has a higher sensitivity compared to the off-line modality so that the PET acquisition time can be greatly reduced from 30 to < 5 min. Features in deep-site, soft-tissue regions were better retained with in-room short PET acquisitions because of the collection of (15)O component and lower biological washout. For soft tissue-equivalent material, the distal fall-off edge of an in-room short acquisition is deeper compared to an off-line equivalent scan, indicating a better coverage of the high-dose end of the beam. In-room PET is a promising low cost, high sensitivity modality for the in vivo verification of proton therapy. Better accuracy in Monte Carlo predictions, especially for biological decay modeling, is necessary.

TI S-Nitrosoglutathione reduces oxidative injury and promotes mechanisms of

CORTICAL IMPACT INJURY; ENDOTHELIAL DYSFUNCTION; EXPERIMENTAL STROKE;
PROTECTS BRAIN
AB Background: Traumatic brain injury (TBI) induces primary and secondary damage in both the endothelium and the brain parenchyma, collectively termed the neurovascular unit. While neurons die quickly by necrosis, a vicious cycle of secondary injury in endothelial cells exacerbates the initial injury in the neurovascular unit following TBI. In activated endothelial cells, excessive superoxide reacts with nitric oxide (NO) to form peroxynitrite. Peroxynitrite has been implicated in blood brain barrier (BBB) leakage, altered metabolic function, and neurobehavioral impairment. S-nitrosoglutathione (GSNO), a nitrosylation-based signaling molecule, was reported not only to reduce brain levels of peroxynitrite and oxidative metabolites but also to improve neurological function in TBI, stroke, and spinal cord injury. Therefore, we investigated whether GSNO promotes the neurorepair process by reducing the levels of peroxynitrite and the degree of oxidative injury.
Methods: TBI was induced by controlled cortical impact (CCI) in adult male rats. GSNO or 3-Morpholinosydnonimine (SIN-1) (50 mu g/kg body weight) was administered orally two hours following CCI. The same dose was repeated daily until endpoints. GSNO-treated (GSNO group) or SIN-1-treated (SIN-1 group) injured animals were compared with vehicle-treated injured animals (TBI group) and vehicle-treated sham-operated animals (Sham group) in terms of peroxynitrite, NO, glutathione (GSH), lipid peroxidation, blood brain barrier (BBB) leakage, edema, inflammation, tissue structure, axon/myelin integrity, and neurotrophic factors.
Results: SIN-1 treatment of TBI increased whereas GSNO treatment decreased peroxynitrite, lipid peroxides/aldehydes, BBB leakage, inflammation and edema in a short-term treatment (4-48 hours). GSNO also reduced brain infarctions and enhanced the levels of NO and GSH. In a long-term treatment (14 days), GSNO protected axonal integrity, maintained myelin levels, promoted synaptic plasticity, and enhanced the expression of neurotrophic factors.
Conclusion: Our findings indicate the participation of peroxynitrite in the pathobiology of TBI. GSNO treatment of TBI not only reduces peroxynitrite but also protects the integrity of the neurovascular unit, indicating that GSNO blunts the deleterious effects of peroxynitrite. A long-term treatment of TBI with the same low dose of GSNO promotes synaptic plasticity and enhances the expression of neurotrophic factors. These results support that GSNO reduces the levels of oxidative metabolites, protects the neurovascular unit, and promotes neurorepair mechanisms in TBI.

AB Background: Six hospitals instituted a voluntary, system-wide, pathway for community acquired pneumonia (CAP). We proposed this study to determine the impact of pathway antibiotics on patient survival, hospital length of stay (LOS), and total hospital cost.
Methods: Data were collected for adults from six U. S. hospitals with a principal CAP discharge diagnosis code, a chest infiltrate, and medical notes indicative of CAP from 2005-2007. Pathway and non-pathway cohorts were assigned according to antibiotics received within 48 hours of admission. Pathway antibiotics included levofloxacin 750 mg monotherapy or ceftriaxone 1000 mg plus azithromycin 500 mg daily. Multivariable regression models assessed 90-day mortality, hospital LOS, total hospital cost, and total pharmacy cost.
Results: Overall, 792 patients met study criteria. Of these, 505 (64%) received pathway antibiotics and 287 (36%) received non-pathway antibiotics. Adjusted means and p-values were derived from Least Squares regression models that included Pneumonia Severity Index risk class, patient age, heart failure, chronic obstructive pulmonary disease, and admitting hospital as covariates. After adjustment, patients who received pathway antibiotics experienced lower adjusted 90-day mortality (p = 0.02), shorter mean hospital LOS (3.9 vs. 5.0 days, p < 0.01), lower mean hospital costs ($2,485 vs. $3,281, p = 0.02), and similar mean pharmacy costs ($356 vs. $442, p = 0.11).
Conclusions: Pathway antibiotics were associated with improved patient survival, hospital LOS, and total hospital cost for patients admitted to the hospital with CAP.

AB Non-small cell lung cancers (NSCLCs) that harbor mutations within the epidermal growth factor receptor (EGFR) gene are sensitive to the tyrosine kinase inhibitors (TKIs) gefitinib and erlotinib. Unfortunately, all patients treated with these drugs will acquire resistance, most commonly as a result of a secondary mutation within EGFR (T790M). Because both drugs were developed to target wild-type EGFR, we hypothesized that current dosing schedules were not optimized for mutant EGFR or to prevent resistance. To investigate this further, we developed isogenic TKI-sensitive and TKI-resistant pairs of cell lines that mimic the behavior of human tumors. We determined that the drug-sensitive and drug-resistant EGFR-mutant cells exhibited differential growth kinetics, with the drug-resistant cells showing slower growth. We incorporated these data into evolutionary mathematical cancer models with constraints derived from clinical data sets. This modeling predicted alternative therapeutic strategies that could prolong the clinical benefit of TKIs against EGFR-mutant NSCLCs by delaying the development of resistance.

AB The NIMA-family kinases Nek9/Nercc1, Nek6 and Nek7 form a signalling module required for mitotic spindle assembly. Nek9, the upstream kinase, is activated during prophase at centrosomes although the details of this have remained elusive. We now identify Plk1 as Nek9 direct activator and propose a two-step activation mechanism that involves Nek9 sequential phosphorylation by CDK1 and Plk1. Furthermore, we show that Plk1 controls prophase centrosome separation through the activation of Nek9 and ultimately the phosphorylation of the mitotic kinesin Eg5 at Ser1033, a Nek6/7 site that together with the CDK1 site Thr926 we establish contributes to the accumulation of Eg5 at centrosomes and is necessary for subsequent centrosome separation and timely mitosis. Our results provide a basis to understand signalling downstream of Plk1 and shed light on the role of Eg5, Plk1 and the NIMA-family kinases in the control of centrosome separation and normal mitotic progression.

AB Many primary vestibular afferents form large cup-shaped postsynaptic terminals (calyces) that envelope the basolateral surfaces of type I hair cells. The calyceal terminals both respond to glutamate released from ribbon synapses in the type I cells and initiate spikes that propagate to the afferent's central terminals in the brainstem. The combination of synaptic and spike initiation functions in these unique sensory endings distinguishes them from the axonal nodes of central neurons and peripheral nerves, such as the sciatic nerve, which have provided most of our information about nodal specializations. We show that rat vestibular calyces express an unusual mix of voltage-gated Na and K channels and scaffolding, cell adhesion, and extracellular matrix proteins, which may hold the ion channels in place. Protein expression patterns form several microdomains within the calyx membrane: a synaptic domain facing the hair cell, the heminode abutting the first myelinated internode, and one or two intermediate domains. Differences in the expression and localization of proteins between afferent types and zones may contribute to known variations in afferent physiology.

AB Although cells undergo dramatic shape changes during cytokinesis, the role of the plasma membrane and lipids is poorly understood. We report that inactivation of glucosyl ceramide synthase (GCS), either by RNAi or with the small molecule PPMP, causes failure of cleavage furrow ingression. Using mass-spectrometry-based global lipid profiling, we identify individual lipids that are enhanced or depleted due to GCS inhibition. We show that GCS inhibition results in the mislocalization of actin and the ERM proteins, key cytoskeletal proteins that connect the plasma membrane to the actin cortex. Our data suggest that ceramides participate in mediating the interactions between the membrane and the cortex.

AB Clear cell ovarian cancer is an epithelial ovarian cancer histotype that is less responsive to chemotherapy and carries poorer prognosis than serous and endometrioid histotypes. Despite this, patients with these tumors are treated in a similar fashion as all other ovarian cancers. Previous genomic analysis has suggested that clear cell cancers represent a unique tumor subtype. Here we generated the first whole genomic expression profiling using epithelial component of clear cell ovarian cancers and normal ovarian surface specimens isolated by laser capture microdissection. All the arrays were analyzed using BRB ArrayTools and PathwayStudio software to identify the signaling pathways. Identified pathways validated using serous, clear cell cancer cell lines and RNAi technology. In vivo validations carried out using an orthotopic mouse model and liposomal encapsulated siRNA. Patient-derived clear cell and serous ovarian tumors were grafted under the renal capsule of NOD-SCID mice to evaluate the therapeutic potential of the identified pathway. We identified major activated pathways in clear cells involving in hypoxic cell growth, angiogenesis, and glucose metabolism not seen in other histotypes. Knockdown of key genes in these pathways sensitized clear cell ovarian cancer cell lines to hypoxia/glucose deprivation. In vivo experiments using patient derived tumors demonstrate that clear cell tumors are exquisitely sensitive to antiangiogenesis therapy (i.e. sunitinib) compared with serous tumors. We generated a histotype specific, gene signature associated with clear cell ovarian cancer which identifies important activated pathways critical for their clinicopathologic characteristics. These results provide a rational basis for a radically different treatment for ovarian clear cell patients.

AB Concussion in youth athletes is a growing problem worldwide. During the past decade, significant progress has been made in standardization of the assessment of young athletes, and a growing appreciation of metabolic vulnerability, activity, and cognitive challenges has led to guidelines and suggestions for rest from the field as well as cognitive rest from school. Outcome data have begun to establish groups linked to symptom class, genetics, and sex who are at risk of worse outcomes from concussions. Decisions regarding return to activity are now based on at-rest symptoms, graded increases in activity, and neuropsychological testing. Using the case of Ms X, a 15-year-old otherwise healthy high school student who fell while skiing, evaluation, prognosis, and management of concussion are discussed.

AB Background: A high quality decision requires that patients who meet clinical criteria for surgery are informed about the options (including non-surgical alternatives) and receive treatments that match their goals. The aim of this study was to evaluate the psychometric properties and clinical sensibility of a patient self report instrument, to measure the quality of decisions about total joint replacement for knee or hip osteoarthritis.
Methods: The performance of the Hip/Knee Osteoarthritis Decision Quality Instrument (HK-DQI) was evaluated in two samples: (1) a cross-sectional mail survey with 489 patients and 77 providers (study 1); and (2) a randomized controlled trial of a patient decision aid with 138 osteoarthritis patients considering total joint replacement (study 2). The HK-DQI results in two scores. Knowledge items are summed to create a total knowledge score, and a set of goals and concerns are used in a logistic regression model to develop a concordance score. The concordance score measures the proportion of patients whose treatment matched their goals. Hypotheses related to acceptability, feasibility, reliability and validity of the knowledge and concordance scores were examined.
Results: In study 1, the HK-DQI was completed by 382 patients (79%) and 45 providers (58%), and in study 2 by 127 patients (92%), with low rates of missing data. The DQI-knowledge score was reproducible (ICC = 0.81) and demonstrated discriminant validity (68% decision aid vs. 54% control, and 78% providers vs. 61% patients) and content validity. The concordance score demonstrated predictive validity, as patients whose treatments were concordant with their goals had more confidence and less regret with their decision compared to those who did not.
Conclusions: The HK-DQI is feasible and acceptable to patients. It can be used to assess whether patients with osteoarthritis are making informed decisions about surgery that are concordant with their goals.

AB The insulin-like growth factor (IGF) axis contains ligands, receptors, substrates, and ligand binding proteins. The essential role of IGF axis in hepatocellular carcinoma (HCC) has been illustrated in HCC cell lines and in animal xenograft models. Preclinical evidence provides ample indication that all four components of IGF axis are crucial in the carcinogenic and metastatic potential of HCC. Several strategies targeting this system including monoclonal antibodies against the IGF 1 receptor (IGF-1R) and small molecule inhibitors of the tyrosine kinase function of IGF-1R are under active investigation. This review describes the most up-to-date understanding of this complex axis in HCC, and provides relevant information on clinical trials targeting the IGF axis in HCC with a focus on anti-IGF-1R approach. IGF axis is increasingly recognized as one of the most relevant pathways in HCC and agents targeting this axis can potentially play an important role in the treatment of HCC.

TI VLDL Hydrolysis by Hepatic Lipase Regulates PPAR delta Transcriptional

AB Background: PPARs (alpha,gamma,delta) are a family of ligand-activated transcription factors that regulate energy balance, including lipid metabolism. Despite these critical functions, the integration between specific pathways of lipid metabolism and distinct PPAR responses remains obscure. Previous work has revealed that lipolytic pathways can activate PPARs. Whether hepatic lipase (HL), an enzyme that regulates VLDL and HDL catabolism, participates in PPAR responses is unknown.
Methods/Principal Findings: Using PPAR ligand binding domain transactivation assays, we found that HL interacted with triglyceride-rich VLDL (>HDL >> LDL, IDL) to activate PPAR delta preferentially over PPAR alpha or PPAR gamma, an effect dependent on HL catalytic activity. In cell free ligand displacement assays, VLDL hydrolysis by HL activated PPAR delta in a VLDL-concentration dependent manner. Extended further, VLDL stimulation of HL-expressing HUVECs and FAO hepatoma cells increased mRNA expression of canonical PPAR delta target genes, including adipocyte differentiation related protein (ADRP), angiopoietin like protein 4 and pyruvate dehydrogenase kinase-4. HL/VLDL regulated ADRP through a PPRE in the promoter region of this gene. In vivo, adenoviral-mediated hepatic HL expression in C57BL/6 mice increased hepatic ADRP mRNA levels by 30%. In ob/ob mice, a model with higher triglycerides than C57BL/6 mice, HL overexpression increased ADRP expression by 70%, demonstrating the importance of triglyceride substrate for HL-mediated PPAR delta activation. Global metabolite profiling identified HL/VLDL released fatty acids including oleic acid and palmitoleic acid that were capable of recapitulating PPARd activation and ADRP gene regulation in vitro.
Conclusions: These data define a novel pathway involving HL hydrolysis of VLDL that activates PPARd through generation of specific monounsaturated fatty acids. These data also demonstrate how integrating cell biology with metabolomic approaches provides insight into specific lipid mediators and pathways of lipid metabolism that regulate transcription.

AB Background: Late diagnosis of HIV infection is a major challenge to the scale-up of HIV prevention and treatment. In 2005 Uganda adopted provider-initiated HIV testing in the health care setting to ensure earlier HIV diagnosis and linkage to care. We provided HIV testing to patients at Mulago hospital in Uganda, and performed CD4 tests to assess disease stage at diagnosis.
Methods: Patients who had never tested for HIV or tested negative over one year prior to recruitment were enrolled between May 2008 and March 2010. Participants who tested HIV positive had a blood draw for CD4. Late HIV diagnosis was defined as CD4 <= 250 cells/mm. Predictors of late HIV diagnosis were analyzed using multi-variable logistic regression.
Results: Of 1966 participants, 616 (31.3%) were HIV infected; 47.6% of these (291) had CD4 counts <= 250. Overall, 66.7% (408) of the HIV infected participants had never received care in a medical clinic. Receiving care in a non-medical setting (home, traditional healer and drug stores) had a threefold increase in the odds of late diagnosis (OR = 3.2; 95% CI: 2.1-4.9) compared to receiving no health care.
Conclusions: Late HIV diagnosis remains prevalent five years after introducing provider-initiated HIV testing in Uganda. Many individuals diagnosed with advanced HIV did not have prior exposure to medical clinics and could not have benefitted from the expansion of provider initiated HIV testing within health facilities. In addition to provider-initiated testing, approaches that reach individuals using non-hospital based encounters should be expanded to ensure early HIV diagnosis.

AB Background-The metabolic syndrome (MetS) is a constellation of clinical features that include central obesity, hypertension, atherogenic dyslipidemia, and insulin resistance. However, the concept remains controversial; it has been debated whether MetS represents nothing more than simultaneous co-occurrence of individual risk factors or whether there are common shared pathophysiological mechanisms that link the individual components.
Methods and Results-To investigate the emergence of metabolic and cardiovascular components during the development of MetS, we identified MetS-predisposed animals (n = 35) in a large population of rhesus macaques (Macaca mulatta, 12.7 +/- 2.9 years old, n = 408), acclimated them to standardized conditions, and monitored the progression of individual component features over 18 months. In 18 MetS animals with recently developed fasting hyperinsulinemia, central obesity, hypertension, and atherogenic dyslipidemia, we found that individual metabolic and cardiovascular components track together during the transition from pre-MetS to onset of MetS; MetS was associated with a 60% impairment of flow-mediated dilation, establishing the mechanistic link with vascular dysfunction. Pioglitazone treatment (3 mg/kg body weight/d for 6 weeks), a peroxisome proliferator-activated receptor gamma agonist, reversibly improved atherogenic dyslipidemia and insulin resistance and fully restored flow-mediated dilation with persistent benefits.
Conclusions-Coemergence of metabolic and cardiovascular components during MetS progression and complete normalization of vascular dysfunction with peroxisome proliferator-activated receptor gamma agonists suggest shared underlying mechanisms rather than separate processes, arguing for the benefit of early intervention of MetS components. Predictive nonhuman primate (NHP) models of MetS should be highly valuable in mechanistic and translational studies on the pathogenesis of MetS in relation to cardiovascular disease and diabetes mellitus.

AB In addition to neutralization, antibodies mediate other antiviral activities including antibody-dependent cellular phagocytosis (ADCP), antibody-dependent cellular cytotoxicity (ADCC), as well as complement deposition. While it is established that progressive HIV infection is associated with reduced ADCC and ADCP, the underlying mechanism for this loss of function is unknown. Here we report considerable changes in FcR expression over the course of HIV infection on both mDCs and monocytes, including elevated Fc gamma RI expression in acute HIV infection and reduced expression of Fc gamma RII and Fc gamma RIIIa in chronic HIV infection. Furthermore, selective blockade of Fc gamma RII alone was associated with a loss in ADCP activity, suggesting that Fc gamma RII plays a central role in modulating ADCP. Overall, HIV infection is associated with a number of changes in FcR expression on phagocytic cells that are associated with changes in their ability to respond to antibody-opsonized targets, potentially contributing to a failure in viral clearance in progressive HIV-1 infection.

AB We have used a microfluidic mass sensor to measure the density of single living cells. By weighing each cell in two fluids of different densities, our technique measures the single-cell mass, volume, and density of approximately 500 cells per hour with a density precision of 0.001 gmL(-1). We observe that the intrinsic cell-to-cell variation in density is nearly 100-fold smaller than the mass or volume variation. As a result, we can measure changes in cell density indicative of cellular processes that would be otherwise undetectable by mass or volume measurements. Here, we demonstrate this with four examples: identifying Plasmodium falciparum malaria-infected erythrocytes in a culture, distinguishing transfused blood cells from a patient's own blood, identifying irreversibly sickled cells in a sickle cell patient, and identifying leukemia cells in the early stages of responding to a drug treatment. These demonstrations suggest that the ability to measure single-cell density will provide valuable insights into cell state for a wide range of biological processes.

AB To guide vaccine design, we assessed whether human monoclonal antibodies (MAbs) b12 and b6 against the CD4 binding site (CD4bs) on HIV-1 gp120 and F240 against an immundominant epitope on gp41 could prevent vaginal transmission of simian HIV (SHIV)-162P4 to macaques. The two anti-gp120 MAbs have similar monomeric gp120-binding properties, measured in vitro, but b12 is strongly neutralizing and b6 is not. F240 is nonneutralizing. Applied vaginally at a high dose, the strongly neutralizing MAb b12 provided sterilizing immunity in seven of seven animals, b6 in zero of five animals, and F240 in two of five animals. Compared with control animals, the protection by b12 achieved statistical significance, whereas that caused by F240 did not. For two of three unprotected F240-treated animals there was a trend toward lowered viremia. The potential protective effect of F240 may relate to the relatively strong ability of this antibody to capture infectious virions. Additional passive transfer experiments also indicated that the ability of the administered anti-gp120 MAbs to neutralize the challenge virus was a critical influence on protection. Furthermore, when data from all of the experiments were combined, there was a significant increase in the number of founder viruses establishing infection in animals receiving MAb b6, compared with other nonprotected macaques. Thus, a gp120-binding, weakly neutralizing MAb to the CD4bs was, at best, completely ineffective at protection. A nonneutralizing antibody to gp41 may have a limited capacity to protect, but the results suggest that the central focus of HIV-1 vaccine research should be on the induction of potently neutralizing antibodies.

These effectors directly target various eukaryotic signaling pathways and cellular processes, often by mimicking the activity of host cell proteins. Effectors of pathogenic Escherichia coli and Salmonella typhimurium can also act as molecular scaffolds that not only recruit but also directly regulate the activity and localization of multiple eukaryotic proteins. By assembling and localizing disparate signaling pathways, the bacteria can reengineer host cell processes to generate novel processes not previously observed in eukaryotic cells.

TI CIN85 drives B cell responses by linking BCR signals to the canonical

AB CIN85, an adaptor protein which binds the C-terminal domain of tyrosine phosphorylated Cbl and Cbl-b, has been thought to be involved in the internalization and subsequent degradation of receptors. However, its physiological function remains unclear. To determine its role in B cells, we used Mb1-cre to generate mice with a B cell-specific deletion of CIN85. These mice had impaired T cell-independent type II antibody responses in vivo and diminished IKK-beta activation and cellular responses to B cell receptor (BCR) cross-linking in vitro. Introduction of a constitutively active IKK-beta construct corrected the defective antibody responses as well as cellular responses in the mutant mice. Together, our results suggest that CIN85 links the BCR to IKK-beta activation, thereby contributing to T cell-independent immune responses.

TOLERANCE; ANTIGEN; INDUCTION; EPITOPE; SUPPRESSION
AB Type 1 diabetes (T1D) results from the destruction of insulin-secreting pancreatic. cells by autoreactive T cells. Insulin is an essential target of the autoimmune attack. Insulin epitopes recognized by diabetogenic T cell clones bind poorly to the class II I-A(g7) molecules of nonobese diabetic (NOD) mice, which results in weak agonistic activity of the peptide MHC complex. Here, we describe a strongly agonistic insulin mimetope that effectively converts naive T cells into Foxp3(+) regulatory T cells in vivo, thereby completely preventing T1D in NOD mice. In contrast, natural insulin epitopes are ineffective. Subimmunogenic vaccination with strongly agonistic insulin mimetopes might represent a novel strategy to prevent T1D in humans at risk for the disease.

AB Objectives To determine the association between physical inactivity (that is, a sedentary lifestyle) and incident idiopathic pulmonary embolism.
Design Prospective cohort study.
Setting Nurses' Health Study.
Participants 69 950 female nurses who completed biennial questionnaires from 1990 to 2008.
Main outcome measures The primary outcome was idiopathic pulmonary embolism confirmed in medical records. Multivariable Cox proportional hazards models controlled for age, body mass index (BMI), energy intake, smoking, pack years, race, spouse's educational attainment, parity, menopause, non-aspirin non-steroidal anti-inflammatory drugs, warfarin, multivitamin supplements, hypertension, coronary heart disease, rheumatological disease, and dietary patterns. The primary exposure was physical inactivity, measured in hours of sitting each day. The secondary exposure was physical activity, measured in metabolic equivalents a day.
Results Over the 18 year study period, there were 268 cases of incident idiopathic pulmonary embolism. There was an association between time of sitting and risk of idiopathic pulmonary embolism (41/104 720 v 16/14 565 cases in most inactive v least inactive in combined data; P<0.001 for trend). The risk of pulmonary embolism was more than twofold in women who spent the most time sitting compared with those who spent the least time sitting (multivariable hazard ratio 2.34, 95% confidence interval 1.30 to 4.20). There was no association between physical activity and pulmonary embolism (P=0.53 for trend).
Conclusions Physical inactivity is associated with incident pulmonary embolism in women. Interventions that decrease time sitting could lower the risk of pulmonary embolism.

AB Background Although practice guidelines recommend outpatient care for selected, haemodynamically stable patients with pulmonary embolism, most treatment is presently inpatient based. We aimed to assess non-inferiority of outpatient care compared with inpatient care.
Methods We undertook an open-label, randomised non-inferiority trial at 19 emergency departments in Switzerland, France, Belgium, and the USA. We randomly assigned patients with acute, symptomatic pulmonary embolism and a low risk of death (pulmonary embolism severity index risk classes I or II) with a computer-generated randomisation sequence (blocks of 2-4) in a 1:1 ratio to initial outpatient (ie, discharged from hospital <= 24 h after randomisation) or inpatient treatment with subcutaneous enoxaparin (>= 5 days) followed by oral anticoagulation (>= 90 days). The primary outcome was symptomatic, recurrent venous thromboembolism within 90 days; safety outcomes included major bleeding within 14 or 90 days and mortality within 90 days. We used a non-inferiority margin of 4% for a difference between inpatient and outpatient groups. We included all enrolled patients in the primary analysis, excluding those lost to follow-up. This trial is registered with ClinicalTrials.gov, number NCT00425542.
Findings Between February, 2007, and June, 2010, we enrolled 344 eligible patients. In the primary analysis, one (0.6%) of 171 outpatients developed recurrent venous thromboembolism within 90 days compared with none of 168 inpatients (95% upper confidence limit [UCL] 2-7%; p=0.011). Only one (0.6%) patient in each treatment group died within 90 days (95% UCL 2.1%; p=0.005), and two (1.2%) of 171 outpatients and no inpatients had major bleeding within 14 days (95% UCL 3.6%; p=0.031). By 90 days, three (1.8%) outpatients but no inpatients had developed major bleeding (95% UCL 4.5%; p=0.086). Mean length of stay was 0.5 days (SD 1.0) for outpatients and 3.9 days (SD 3.1) for inpatients.
Interpretation In selected low-risk patients with pulmonary embolism, outpatient care can safely and effectively be used in place of inpatient care.

AB Introduction: Psychiatric conditions affect multiple areas of psychosocial functioning, including functioning in the workplace. The purpose of this study was to establish norms for absenteeism (work days missed due to mental or physical illness) and work performance (quality of work performed when at work) for healthy individuals.
Methods: We selected 300 individuals without psychiatric or medical conditions from the National Comorbidity Survey Replication study (NCS-R). Absenteeism and work performance were assessed using the NCS-R version of the Health and Work Performance Questionnaire (HPQ).
Results: Employees missed an average of 5.1 days of work in the past year. Absenteeism varied across occupations, with performers of routine tasks, office clerks, and professionals exhibiting the greatest variance in days missed. Work performance ratings were skewed toward high performance ratings and did not differ across occupations. Gender, age, race/ethnicity, and education level did not substantially moderate absenteeism and work performance norms.
Discussion: Skewed ratings for work performance are consistent with previous findings using the HPQ. This may reflect a general tendency that individuals rate themselves favorably when they compare themselves to others.
Conclusion: This study provides normative tables for absenteeism and work performance in individuals without psychiatric or medical conditions, against which individuals with such conditions may be compared.

AB We suggest that Diffuse Correlation Spectroscopy (DCS) measurements of tissue blood flow primarily probe relative red blood cell (RBC) motion, due to the occurrence of multiple sequential scattering events within blood vessels. The magnitude of RBC shear-induced diffusion is known to correlate with flow velocity, explaining previous reports of linear scaling of the DCS "blood flow index" with tissue perfusion despite the observed diffusion-like auto-correlation decay. Further, by modeling RBC mean square displacement using a formulation that captures the transition from ballistic to diffusive motion, we improve the fit to experimental data and recover effective diffusion coefficients and velocity de-correlation time scales in the range expected from previous blood rheology studies.

AB Background: Despite advances in traumatic wound care and management, infections remain a leading cause of mortality, morbidity and economic disruption in millions of wound patients around the world. Animal models have become standard tools for studying a wide array of external traumatic wound infections and testing new antimicrobial strategies.
Results: Animal models of external traumatic wound infections reported by different investigators vary in animal species used, microorganism strains, the number of microorganisms applied, the size of the wounds and for burn infections, the length of time the heated object or liquid is in contact with the skin.
Methods: This review covers experimental infections in animal models of surgical wounds, skin abrasions, burns, lacerations, excisional wounds and open fractures.
Conclusions: As antibiotic resistance continues to increase, more new antimicrobial approaches are urgently needed. These should be tested using standard protocols for infections in external traumatic wounds in animal models.

AB Tripartite motif-containing (TRIM) E3 ligases are a recently identified family of proteins with potent antiviral activity in mammalian cells. The prototype TRIM E3 ligase, TRIM5a was initially identified as a species-specific antiviral restriction factor in Old World monkeys but subsequent studies suggest some antiviral activity by several TRIM E3 ligases in human cells. However, the mechanisms of antiviral activity by these proteins and their transcriptional, translational and post-translational regulation are poorly understood. Furthermore, the contribution of TRIM E3 ligases to relative resistance or viral control in vivo is largely unknown. Emerging data from our laboratory and other groups suggest that these proteins may have antiviral activity in vivo and contribute to HIV pathogenesis. Considering the significant difficulties so far encountered in developing an effective HIV vaccine and with the use of antiretroviral therapies, it will be important to further investigate the potential of TRIM E3 ligases as novel prophylactics or therapies.

AB Because products of conception often contain maternal and vinous tissues, the determination of maternal and vinous genotypes based on genetic polymorphisms can help discern maternal and paternal chromosomal contribution and aid in the diagnosis of hydatidiform moles. Polymorphic deletion probe (PDP) fluorescence in situ hybridization (FISH) probes based on copy number variants are highly polymorphic and allow in situ determination of genetic identity. By using three informative PDPs on chromosomes 2p, 4q, and 8p, we compared maternal with vinous genotypes and determined the ploidy of vinous tissue. PDP FISH was performed on 13 complete moles, 13 partial moles, 13 nonmolar abortions, and an equivocal hydropic abortion. PDP FISH permitted definitive diagnosis of complete moles in five of 13 cases for which maternal and vinous genotypes were mutually exclusive. A complete mole was highly suspected when all three PDP loci showed homozygous vinous genotypes. The diagnosis of a complete mole by PDP FISH yielded a theoretical test sensitivity of 87.5%, specificity of 91.8%, an observed test sensitivity of 100%, and specificity of 92.3%. Triploidy was observed in all partial moles, in which diandric triploidy was confirmed in six cases. In the equivocal hydropic abortion, PDP FISH combined with p57 immunofluorescence revealed placental androgenetic/biparental mosaicism. PDP FISH can be used in clinical practice and research studies to subclassify hydatidiform moles and evaluate unusual products of conception.

TI Eliminating Murine Norovirus by Cross-Fostering
SO JOURNAL OF THE AMERICAN ASSOCIATION FOR LABORATORY ANIMAL SCIENCE
LA English
DT Article
ID MICE; INFECTION; VIRUS; ERADICATION; PREVALENCE; IMMUNITY
AB Murine norovirus (MNV) is a newly discovered and extremely prevalent pathogen of laboratory mouse colonies. MNV causes severe disease in some immunocompromised mouse strains and can cause persistent infections even in immunocompetent mice. Despite the fact that immunocompetent mice are generally asymptomatic, the possibility that MNV infection might alter immune responses makes its eradication a potentially useful goal for many facilities. Initial attempts by others to use a strategy of testing and culling were unsuccessful, whereas complete depopulation and facility decontamination was successful. However, these measures may be impractical, and finding less drastic approaches seemed prudent. Based on a report that cross-fostering of pups from MNV-positive mothers to MNV-negative ones could be successful in experimental MNV infection, we undertook a comprehensive fostering program using Swiss Webster mothers, careful sanitary measures, and fecal PCR testing to eradicate the virus from a mouse colony recently infected with MNV. We successfully decontaminated 17 of 18 (94%) litters and managed to prevent spread when a new MNV-infected mouse strain entered quarantine at our facility. These results suggest that cross-fostering, when performed in a setting of excellent sanitary procedures, may be practical for the large number of mouse facilities in which MNV is endemic.

AB BACKGROUND: With advances in oncologic treatment, cosmesis after mastectomy has assumed a pivotal role in patient and provider decision making. Multiple studies have confirmed the safety of both chemotherapy before breast surgery and immediate reconstruction. Little has been written about the effect of neoadjuvant chemotherapy on decisions about reconstruction. METHODS: The authors identified 665 patients with stage I through III breast cancer who received chemotherapy and underwent mastectomy at Dana-Farber/Brigham & Women's Cancer Center from 1997 to 2007. By using multivariate logistic regression, reconstruction rates were compared between patients who received neoadjuvant chemotherapy (n = 180) and patients who underwent mastectomy before chemotherapy (n = 485). The rate of postoperative complications after mastectomy was determined for patients who received neoadjuvant chemotherapy compared with those who did not. RESULTS: Reconstruction was performed immediately in 44% of patients who did not receive neoadjuvant chemotherapy but in only 23% of those who did. Twenty-one percent of neoadjuvant chemotherapy recipients and 14% of adjuvant-only chemotherapy recipients underwent delayed reconstruction. After controlling for age, receipt of radiotherapy, and disease stage, neoadjuvant recipients were less likely to undergo immediate reconstruction (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.37, 0.87) but were no more likely to undergo delayed reconstruction (OR, 1.29; 95% CI, 0.75, 2.20). Surgical complications occurred in 30% of neoadjuvant chemotherapy recipients and in 31% of adjuvant chemotherapy recipients. CONCLUSIONS: The current results suggest that patients who receive neoadjuvant chemotherapy are less likely to undergo immediate reconstruction and are no more likely to undergo delayed reconstruction than patients who undergo surgery before they receive chemotherapy.

AB OBJECTIVES: To examine the associations between insulin resistance and changes in body composition in older men without diabetes mellitus.
DESIGN: Longitudinal cohort study of older men participating in the Osteoporotic Fractures in Men (MrOS) study.
SETTING: Six U.S. clinical centers.
PARTICIPANTS: Three thousand one hundred thirty-two ambulatory men aged 65 and older at baseline.
MEASUREMENTS: Baseline insulin resistance was calculated for men without diabetes mellitus using the homeostasis model assessment of insulin resistance (HOMA-IR). Total lean, appendicular lean, total fat, and truncal fat mass were measured using dual energy X-ray absorptiometry scans at baseline and 4.6 perpendicular to 0.3 years later in 3,132 men with HOMA-IR measurements.
RESULTS: There was greater loss of weight, total lean mass, and appendicular lean mass and less gain in total fat mass and truncal fat mass with increasing quartiles of HOMA-IR (P<.001 for trend). Insulin-resistant men in the highest quartile had higher odds of 5% or more loss of weight (odds ratio (OR) = 1.88, 95% confidence interval (CI) = 1.46-2.43), total lean mass (OR = 2.09, 95% CI = 1.60-2.73) and appendicular lean mass (OR = 1.57, 95% CI = 1.27-1.95) and lower odds of 5% or more gain in total fat mass (OR = 0.56, 95% CI = 0.45-0.68) and truncal fat mass (OR = 0.52, 95% CI = 0.42-0.64) than those in the lowest quartile. These findings remained significant after accounting for age, site, baseline weight, physical activity, and change in physical activity. These associations were also independent of other metabolic syndrome features and medications.
CONCLUSION: Greater lean mass loss and lower fat mass gain occurred in insulin-resistant men without diabetes mellitus than in insulin-sensitive men. Insulin resistance may accelerate age-related sarcopenia. J Am Geriatr Soc 59:1217-1224, 2011.

AB It is now well accepted that besides the cholesterol associated mechanisms of atherogenesis, inflammation plays a crucial role in all stages of the development of the atherosclerotic lesion. This 'inflammation hypothesis' raises the possibility that through systemic elevations of pro-inflammatory cytokines, periodontal diseases might also contribute to systemic inflammation and, therefore, to atherogenesis. In fact, there is evidence that periodontal diseases are associated with higher systemic levels of high-sensitivity C-reactive protein and a low grade systemic inflammation. This phenomenon has been explained based on mechanisms associated with either the infectious or the inflammatory nature of periodontal diseases. The purposes of this article were to review (1) the evidence suggesting a role for oral bacterial species, particularly periodontal pathogens, in atherogenesis; (2) the potential mechanisms explaining an etiological role for oral bacteria in atherosclerosis; (3) the evidence suggesting that periodontal infections are accompanied by a heightened state of systemic inflammation; (4) the potential sources of systemic inflammatory biomarkers associated with periodontal diseases; and (5) the effects of periodontal therapy on systemic inflammatory biomarkers and cardiovascular risk.

AB The mechanism and formation of cancer have always been topics of interest for scientists, even for doctors in ancient times. Nowadays a great role for cancer is played by psychological stress which promotes relevant changes in neuronal activity and gene regulations across the different brain areas. It has been reported by many authors that stress can have an important role in the immune system and may be relevant in the formation of cancer. Our observations, in accordance with other research studies, confirm the importance of the influence of depression, linked to neuroendocrine stress, on the enhancement of cancer pathogenesis by inhibiting anti-tumor immune responses. In this article we review the past and present history of the relationship between cancer and psychology.

AB The Independent Payment Advisory Board (IPAB) is a vastly powerful component of the president's health care reform law, with authority to issue recommendations to reduce the growth in Medicare spending, providing recommendations to be considered by Congress and implemented by the administration on a fast track basis. Ever since its inception, IPAB has been one of the most controversial issues of the Patient Protection and Affordable Care Act (ACA), even though the powers of IPAB are restricted and multiple sectors of health care have been protected in the law.
IPAB works by recommending policies to Congress to help Medicare provide better care at a lower cost, which would include ideas on coordinating care, getting rid of waste in the system, providing incentives for best practices, and prioritizing primary care. Congress then has the power to accept or reject these recommendations. However, Congress faces extreme limitations, either to enact policies that achieve equivalent savings, or let the Secretary of Health and Human Services (HHS) follow IPAB's recommendations. IPAB has strong supporters and opponents, leading to arguments in favor of or against to the extreme of introducing legislation to repeal IPAB.
The origins of IPAB are found in the ideology of the National Institute for Health and Clinical Excellence (NICE) and the impetus of exploring health care costs, even though IPAB's authority seems to be limited to Medicare only. The structure and operation of IPAB differs from Medicare and has been called the Medicare Payment Advisory Commission (MedPAC) on steroids. The board membership consists of 15 full-time members appointed by the president and confirmed by the Senate with options for recess appointments.
The IPAB statute sets target growth rates for Medicare spending. The applicable percent for maximum savings appears to be 0.5% for year 2015, 1% for 2016, 1.25% for 2017, and 1.5% for 2018 and later. The IPAB Medicare proposal process involves mandatory recommendations and advisory recommendations with multiple reporting requirements. However, although IPAB has been described as having limited authority, some believe that it has unlimited authority due to the lack of judicial review and the requirement of two-thirds of the Congress to override any recommendations by IPAB.

AB A 40-year-old man presented with a pigmented lesion of the palpebral conjunctiva and margin of the right lower eyelid. Because of suspicion of melanoma, the lesion was resected. Microscopic examination revealed 2 distinct components: a dominant blue nevus in the tarsus consisting of bland pigmented spindle and epithelioid cells that dissected among the orbicularis muscle fibers and meibomian glands, and a small subepithelial nevomelanocytic component with no overlying junctional activity. The diagnosis of a combined nevus was supported by minimal Ki-67 nuclear immunoreactivity. While the current lesion was proved to be an atypical nevus, all palpebral pigmented lesions should be routinely excised because many are melanomas.

AB Tremendous advances in technologies have allowed the attainment of powerful insights into the molecular and genetic determinants that drive human cancers. However, this acquired knowledge has been translated into effective therapeutics very slowly, in part due to difficulty in predicting which drug or drug combination is likely to be effective in the complex mutational background of human cancers. To address this difficulty we have proposed and initiated the "co-clinical trial" project, in which we exploit mouse models that faithfully replicate the variety of mutational events observed in human cancers, to conduct preclinical trials that parallel ongoing human phase I/II clinical trials. Here, we focus on concepts relevant to the application of this novel paradigm and the essential components required for its implementation to ultimately achieve the rational and rapid development of new therapeutic treatments.

AB Initiation of pancreatic ductal adenocarcinoma (PDAC) is driven by oncogenic KRAS mutation, and disease progression is associated with frequent loss of tumor suppressors. In this study, human PDAC genome analyses revealed frequent deletion of the PTEN gene as well as loss of expression in primary tumor specimens. A potential role for PTEN as a haploinsufficient tumor suppressor is further supported by mouse genetic studies. The mouse PDAC driven by oncogenic Kras mutation and Pten deficiency also sustains spontaneous extinction of Ink4a expression and shows prometastatic capacity. Unbiased transcriptomic analyses established that combined oncogenic Kras and Pten loss promotes marked NF-kappa B activation and its cytokine network, with accompanying robust stromal activation and immune cell infiltration with known tumor-promoting properties. Thus, PTEN/phosphoinositide 3-kinase (PI3K) pathway alteration is a common event in PDAC development and functions in part to strongly activate the NF-kappa B network, which may serve to shape the PDAC tumor microenvironment.
SIGNIFICANCE: Detailed molecular genetics studies established that PTEN operates as a haploinsufficient tumor suppressor to promote metastatic PDAC development. The strong activation of the NF-kappa B-cytokine program in Pten-deficient tumors provides additional avenues for targeted therapies in tumors with altered PI3K regulation.

AB We demonstrate that phosphatidylinositol 3-kinase (PI3K) pathway aberrations occur in >80% of endometrioid endometrial cancers, with coordinate mutations of multiple PI3K pathway members being more common than predicted by chance. PIK3R1 (p85 alpha) mutations occur at a higher rate in endometrial cancer than in any other tumor lineage, and PIK3R2 (p85 beta), not previously demonstrated to be a cancer gene, is also frequently mutated. The dominant activation event in the PI3K pathway appears to be PTEN protein loss. However, in tumors with retained PTEN protein, PI3K pathway mutations phenocopy PTEN loss, resulting in pathway activation. KRAS mutations are common in endometrioid tumors activating independent events from PI3K pathway aberrations. Multiple PIK3R1 and PIK3R2 mutations demonstrate gain of function, including disruption of a novel mechanism of pathway regulation wherein p85 alpha dimers bind and stabilize PTEN. Taken together, the PI3K pathway represents a critical driver of endometrial cancer pathogenesis and a novel therapeutic target.
SIGNIFICANCE: Our data indicate that the PI3K pathway is targeted in the vast majority of endometrioid endometrial cancers leading to PI3K pathway activation. Frequent oncogenic mutations in PIK3R1 and PIK3R2 provide evidence for their role in endometrial cancer pathophysiology with patient-specific mutations revealing a novel mechanism by which p85 alpha regulates the PI3K pathway through stabilizing PTEN.

AB At least 2 different types of cells, hematopoietic and mesenchymal, are present in the adult bone marrow, in addition to endothelial cells. Hematopoietic and mesenchymal cells are believed to originate from hematopoietic stem cells (HSC) and mesenchymal stem cells (MSC), respectively. The bone marrow stroma, a cellular microenvironment that supports HSC, is composed of non-hematopoietic cells and contains MSC. A unique expansion of the bone marrow stroma, also known as marrow fibrosis, is the hallmark of a variety of disorders including hyperparathyroidism and fibrous dysplasia. PTH is the first bone anabolic agent approved by US Food and Drug Administration for the treatment of osteoporosis. Recent studies have suggested that PTH treatment may affect the number of hematopoietic stem cells in the bone marrow and their mobilization into the bloodstream. In addition, cells with classical features of mesenchymal stem cells/progenitors have been shown to express receptors for PTH, and to increase in number and undergo redistribution in the adult bone marrow upon PTH treatment. In this review, we will summarize the up-to-date knowledge on PTH and its relation to stem cells. We will also discuss the contribution of different cell types to the development of marrow fibrosis and the involvement of PTH signaling in this pathology. (J. Endocrinol.

AB Purpose: There is limited access to psychiatric medication follow-up services at safety-net clinics serving the largely homeless minority population of Los Angeles' skid-row district. This paper describes the process of establishing a pharmacist-run psychiatric medication management service, the types of interventions provided by the psychiatric pharmacist, and patient and provider satisfaction with the service.
Methods: The establishment of a collaborative practice agreement between primary care physicians and psychiatric pharmacists is described along with the patient demographics and types of pharmacist interventions. Primary care physicians were surveyed regarding their comfort level with managing psychiatric illness and prescribing psychotropic medications. They were also asked about their opinion of psychiatric pharmacist medication management services. An anonymous patient satisfaction survey was also administered.
Results: The development of psychiatric pharmacy services is described. The types of interventions included initiating drug therapy, adjusting dosages, discontinuing drug therapy, and providing medication education. Primary care providers were not comfortable in providing psychiatric medication follow-up for patients beyond uncomplicated depression and anxiety disorders. They expressed an overall positive view of psychiatric pharmacist services for their patients with established psychiatric diagnoses. Patient satisfaction ratings were high.
Conclusions: A psychiatric pharmacist-run medication management service in collaboration with primary care providers can improve access to mental health services in safety-net clinics with good provider and patient satisfaction.

AB Although the goals of end-of-life care and hospice are to mitigate suffering and improve quality of life for patients with terminal illnesses, they remain underutilized by a significant number of African Americans. While sociocultural issues play a role in the underutilization of these resources among African Americans, other confounding factors affect the ability of African Americans to adequately access quality care at the end of life. Here, the authors examine the various barriers preventing increased use of hospice care and palliative therapy among African Americans. A particular focus of this examination will revolve around suggestions for increasing the use of end-of-life care among African Americans in the future.

AB There is a delicate balance between pro-angiogenic stimuli and anti-angiogenic stimuli in the normal cornea. This balance allows the cornea to normally exist in a relatively avascular state, which is needed for optical clarity and vision. However, in the setting of inflammation, this balance may be shifted in favor of neovascularization.
This paper reviews the literature on corneal inflammatory neovascularization beginning with the pro-angiogenic factors, such as Vascular Endothelial Growth Factor and Fibroblast Growth Factor, which help to facilitate the development of new corneal vessels. Subsequently the anti-angiogenic factors and their role in preventing neovascularization in the normal cornea are reviewed. Finally, a review of several etiologies of inflammatory neovascularization is presented with attention to the processes that allow the pro-angiogenic stimuli to overwhelm the anti-angiogenic factors.

AB Relapsing polychondritis (RP) is a rare systemic autoimmune disease characterized by episodic inflammation of cartilaginous tissues throughout the body. It is distinguished by recurrent bouts of inflammation, which lead to the permanent destruction of the involved structures. It can be a life-threatening, debilitating, and frightening disease and is often difficult to diagnose in its early stages. Ocular manifestations have been reported to occur in up to 65% of cases and include proptosis, eyelid edema, extraocular muscles palsy, episcleritis, scleritis, conjunctivitis, corneal infiltrate, peripheral ulcerative keratitis, corneal thinning or perforation, iridocyclitis, cataract, retinopathy, exudative retinal detachment, and optic neuritis. Corticosteroids remain the mainstay of treatment for RP; however, other treatment modalities include nonsteroidal anti-inflammatory drugs, colchicine, dapsone, and immunomodulatory drugs. This article reviews the literature and summarizes the epidemiology, pathogenesis, clinical features, treatment, and prognosis of the systemic and ocular manifestations of RP.

AB Glaucoma is one of the leading causes of blindness worldwide. The current view of glaucoma is that it is a multifactorial disease. Elevated IOP is a recognized etiologic factor which can trigger initial damage through biomechanical and ischemic injury to the retinal ganglion cells. However, elevated intraocular pressure cannot be entirely responsible for the development of glaucoma. Accumulating evidence suggests that abnormal immunity may be contributing to the glaucomatous optic neuropathy. Autoimmunity may be responsible for initiating or exacerbating glaucoma. This review provides an evaluation of the potential role of autoimmunity in some patients with glaucoma.

AB In 1948, Posner and Schlossman first reported glaucomatocyclitic crisis, an uncommon form of glaucoma characterized by recurrent unilateral episodes of markedly elevated intraocular pressure (IOP) with mild idiopathic anterior chamber inflammation. The exact etiology of glaucomatocyclitic crisis is not clear. Although it is typically a self-limited condition, some cases with advanced optic nerve cupping and associated visual field loss have been reported. Diagnosis of Posner-Schlossman syndrome is difficult, and it may mimic a variety of ocular disorders. Treatment of this syndrome is directed towards controlling the inflammation and associated IOP elevation.

AB Glaucoma is a disease process characterized by progressive optic nerve damage and corresponding visual field loss. It may be further categorized into either primary open-angle glaucoma or secondary glaucoma. These secondary glaucomas include glaucomas associated with uveitis and inflammation. Prostaglandin analogs (PGA) have been used to help lower intraocular pressure (IOP) in these often difficult to manage eyes. However, controversy exists concerning their use in uveitic patients due to the theoretically higher risk of anterior uveitis, development of cystoid macular edema (CME), and reactivation of herpes simplex keratitis (HSK). There is little evidence that PGA disrupt the blood-aqueous barrier and only anecdotal evidence suggesting an increased risk of these rare findings. PGA may be used in uveitic glaucoma when other topical treatments have not lowered IOP to the patient's target range.

AB Behcet's Disease (BD) is a multisystem inflammatory disorder of uncertain etiology with a variety of potential manifestations throughout the body, and its ocular complications are some of its most devastating. Treatment with immunosuppressive agents has improved outcomes, but many patients suffer from disease that responds poorly to conventional therapies. Because of this, therapy with a variety of biological response modifiers has been employed. The earliest was interferon-alpha, and a multitude of reports have described its benefits for the uveitis associated with Behcet's Disease. Many patients enjoy durable remissions of their ocular inflammatory disease even after discontinuation of therapy, but side-effects are almost universal and some can be dangerous. Of the newer biological response modifiers, infliximab, a monoclonal antibody to TNF-alpha, has been most extensively studied. It is reported to be rapidly effective in many cases of Behcet's Disease uveitis, though with conflicting data as to the ability to induce durable remission after cessation of treatment. Side-effects are relatively rare, but may be serious. Several reports have been published on the use of other biologic agents, including adalimumab (a humanized antibody to TNF-alpha), etanercept (a molecule that resembles the TNF-alpha receptor), and rituximab (an antibody to CD20 that depletes the body of CD20-positive B cells). Of the three of these, adalimumab has the most promising initial evidence, etanercept has very few positive reports in patients with BD uveitis (and is likely ineffective in uveitis in general), and rituximab is lacking data. Although randomized controlled trials are almost completely lacking, currently available evidence is promising that biologic agents can prove an invaluable addition to the armamentarium of the practitioner treating patients with BD uveitis.

AB Sympathetic ophthalmia is a rare, bilateral granulomatous panuveitis following accidental or surgical trauma to one eye. The pathophysiology is not clearly understood, but is believed to be a T-cell mediated autoimmune response. Clinical presentation most often occurs within the first year after trauma; anteriorly it manifests as a chronic or acute uveitis with mutton-fat keratic precipitates, while posteriorly it is often accompanied by yellowish-white choroidal lesions or Dalen-Fuchs nodules. The mainstay of treatment consists of systemic anti-inflammatory agents such as oral corticosteroids, or other immunosuppressive agents. Newer treatments include intravitreal injections of steroids in combination with systemic therapy, periocular injections of steroids without systemic therapy, and injections of infliximab, an anti-vascular endothelial growth factor.

AB Paraneoplastic retinopathies comprise a diverse group of immune-mediated conditions affecting the eye. Cancer-associated retinopathy (CAR) typically has a sudden onset of severe visual loss and an ominous association with an occult malignancy. CAR is one of the best studied and better understood conditions in the multifarious group of autoimmune retinopathies. Recent developments have correlated the disease presentation, course, and therapeutic response to the underlying immune mediators and the inciting antigens. Signaling involving cytotoxic T-lymphocytes antigen 4 (CTLA-4) and vascular endothelial growth factor (VEGF) receptor-1 appears to play a role in the pathogenesis and may offer novel avenues for therapeutic intervention in CAR. Future developments in rapid identification and longitudinal quantification of antibody levels would enable individualized management in these patients. The goal of this review is to analyze the clinical features of diagnosis and management of retinopathy in the context of recent advances in the elucidation of CAR pathogenesis.

RETINOCHOROIDOPATHY
AB Birdshot chorioretinopathy (BSCR) is a rare form of posterior uveitis in which hypopigmented choroidal lesions are scattered throughout the posterior pole. In order to avoid the poor natural history of BSCR, many practitioners would argue that it is critical to diagnose and carefully monitor the often subtle activity of this disease; BSCR can progress insidiously in a white and painless eye, and treatment algorithms based on visual acuity, vitreous inflammation, and retinal vascular leakage of fluorescein alone have been ineffective. This article reviews the various modalities that can be used to diagnose and monitor BSCR, including the clinical and ophthalmoscopic features, diagnostic criteria, electroretinography (ERG-full field, multifocal, and pattern), fluorescein angiography (FA), indocyanine green (ICG) angiography, optical coherence tomography (OCT), fundus autofluorescence (AF), visual fields, HLA A29 testing, and other laboratory testing. HLA-A29 testing can be useful in diagnostically borderline cases, but a positive test is not as useful as one might think in cases where the clinical suspicion for BSCR is low. Out of all the testing modalities, the ERG has been studied most extensively in its relationship to successful treatment. The key parameter is the 30 Hz flicker implicit time, which is abnormal in 70% of patients at baseline. A normal implicit time is correlated with the chance that a patient can be successfully tapered from systemic immunomodulatory therapy without recurrence. Alternatively, some practitioners use ICG angiography or visual field testing for adjunctive monitoring. OCT is used most commonly to follow macular edema. While there is no consensus on how to best monitor disease activity, our institution uses serial ERGs as an adjunct to the normal exam.
