AB Acute coronary syndromes are a leading cause of morbidity and mortality worldwide. The mechanisms underlying the triggering of these events are diverse and include increased coronary and systemic inflammatory activity dominant prothrombotic conditions, increased biomechanical stress on coronary arteries, variations in the coronary arterial tone, disturbed haemodynamic homoeostasis, and altered myocardial metabolic balance. There is experimental evidence that acute infections can promote the development of acute coronary syndromes, and clinical data strongly support a role for acute infections in triggering these events. In our Review, we summarise the pathogenesis of coronary artery disease and present the evidence linking acute infections with the development of acute coronary syndromes. Greater awareness of this association is likely to encourage research into ways of protecting patients who are at high risk.

AB Objectives/Hypothesis: Assess the safety and efficacy of combined antegrade and retrograde esophageal dilation (CARD) for complete esopbageal stenosis following head and neck cancer (HNC) treatment. Review HNC dysphagia management.
Study Design: Retrospective review of all patients undergoing CARD following HNC treatment between May 2001 and September 2008.
Methods: Forty-five patients were identified for review. Parameters assessed included: ability to obtain intraoperative esophageal patency, complications, number of dilations required, diet, and gastric tube (GT) status. Factors associated with dilation failure were analyzed.
Results: Intraoperative esophageal patency was obtained in 91% of patients. Median number of all dilations per patient was three. Median number of CARDs per patient was one. Resumption of oral intake occurred in 36/45 (80%). Diet results included: regular or soft diet 32/45 (71%), GT removal 27/45 (60%), and GT dependence with nothing by mouth 9/45 (20%). Laryngeal and pharyngeal stenosis, radionecrosis, tracheotomy dependence, and elongated stenosis were associated with dilation failure. Complications occurred in 18/63 (29%) CARD procedures: eight pneumomediastinum, seven GT site problems, two esophageal perforations, and one pharyngeal infection. All complications resolved spontaneously or with. minimal interventions.
Conclusions: CARD was safe and effective. Intraoperative patency was achieved in 91% of patients. Eighty percent resumed oral intake. The majority of patients had their GTs removed and resumed a soft or regular diet. Dilation failure was associated with laryngeal, pharyngeal, and excessively long esophageal stenosis, often resulting from radionecrosis. Complications were minor. CARD should be considered before relegating patients with complete esophageal stenosis to chronic GT dependence or subjecting them to laryngopharyngo esophagectomy.

AB Objectives/Hypothesis: To explore whether adipose-derived stem/stromal cells (ASCs) have therapeutic potential for treating scarred superficial lamina propria through the effects of secreted hepatocyte growth factor (HGF) on scar fibroblasts.
Study Design: In vitro study using coculture system.
Methods: Scar fibroblasts (SFs) were isolated from ferret vocal folds electrocauterized 2 weeks previously. ASCs were isolated from ferret lipoaspirated subcutaneous abdominal fat. For coculture experiments, the two cell types were combined in Transwell plates for 6 days, followed by 1 or 3 days of monoculture after removing the upper chamber. Assays were then performed on cells and media from the bottom chamber. We measured: 1) the production of hyaluronic acid (RA), collagen and HGF via enzyme-linked immunosorbent assays, 2) the expression of alpha-smooth muscle actin (alpha-SMA), 3) cell proliferation, and 4) apoptosis of SFs (2, 3, and 4 via flow cytometry). Other experiments examined the effects of HGF on SFs and the effects of HGF neutralization in the coculture system.
Results: Coculture led to significant decreases in SF collagen production (P <.05), cell proliferation (P <.05), and a-SMA expression (P <.05), whereas HA production increased (P <.05). Coculture also increased HGF secretion from ASCs (P <.05). Neutralization of HGF abolished the inhibitory effects of ASCs on SF collagen synthesis (P <.05).
Conclusions: ASCs influence SFs to adopt a less fibrotic profile. It appears that HGF is at least one of the soluble factors responsible for this effect. Implanted ASCs could potentially ameliorate vocal fold scar by acting as long-term, intrinsic sources of HGF.

AB Background and Objectives: Complete blanching of port wine stain (PWS) birthmarks after laser therapy is rarely achieved for most patients. We postulate that the low therapeutic efficacy or treatment failure is caused by regeneration and revascularization of photocoagulated blood vessels due to angiogenesis associated with the skin's normal wound healing response. Rapamycin (RPM), an antiangiogenic agent, has been demonstrated to inhibit growth of pathological blood vessels. Our objectives were to (1) investigate whether topical RPM can inhibit reperfusion of photocoagulated blood vessels in an animal model and (2) determine the effective RPM concentration required to achieve this objective.
Study Design/Materials and Methods: For both laser-only and combined laser and RPM treated animals, blood vessels in the dorsal window chambers implanted on golden Syrian banisters were photocoagulated with laser pulses. Structural and flow dynamics of blood vessels were documented with color digital photography and laser speckle imaging to evaluate photocoagulation and reperfusion. For the combined treatment group, topical RPM was applied to the epidermal side of the window daily for 14 days after laser exposure.
Results: In the laser-only group, 23 out of 24 photocoagulated blood vessels reperfused within 5-14 days. In the combined treatment group with different RPM formulae and concentrations, the overall reperfusion rate of 36% was much lower as compared to the laser-only group. We also found that the reperfusion rate was not linearly proportional to the RPM concentration.
Conclusions: With topical RPM application, the frequency of vessel reperfusion was considerably reduced, which implies that combined light and topical antiangiogenic therapy might be a promising approach to improve the treatment efficacy of PWS birthmarks.

AB Background and Objectives: Ablative fractional resurfacing (AFR) creates vertical channels that might assist the delivery of topically applied drugs into skin. The purpose of this study was to evaluate drug delivery by CO2 laser AFR using methyl 5-aminolevulinate (MAL), a porphyrin precursor, as a test drug.
Materials and Methods: Two Yorkshire swine were treated with single-hole CO2 laser AFR and subsequent topical application of MAL (Metvix(R), Photocure ASA, Oslo, Not-way), placebo cream and no drug. MAL-induced porphyrin fluorescence was measured by fluorescence microscopy at skin depths down to 1,800 mu m. AFR was performed with a 10.6 mu m wavelength Prototype CO2 laser, using stacked single pulses of 3 millisecond and 91.6 mJ pet, pulse.
Results: AFR created cone-shaped channels of approximately 300 mu m diameter and 1,850 mu m depth that were Surrounded by a 70 mu m thin layer of thermally coagulated dermis. There was no porphyrin fluorescence in placebo cream or untreated skin sites. AFR followed by MAL application enhanced drug delivery with significantly higher porphyrin fluorescence of hair follicles (P < 0.0011) and dermis (P < 0.0433) versus MAL alone at skin depths of 120, 500, 1,000, 1,500, and 1,800 pro. AFR before MAL application also enhanced skin surface (epidermal) porphyrin fluorescence. Radial diffusion of MAL from the laser-created channels into surrounding dermis was evidenced by uniform porphyrin fluorescence up to 1,500 mu m from the holes (1,000, 1,800 mu m depths). Skin massage after MAL application did not affect MAL-induced porphyrin fluorescence after AFR.
Conclusions: Ablative fractional laser treatment facilitates delivery of topical MAL deeply into the skin. For the conditions of this study, laser channels approximately 3 mm apart followed by MAL application could produce porphyrins throughout essentially the entire skin. AFR appears to be a clinically practical means for enhancing uptake of MAL, a photodynamic therapy drug, and presumably many other topical skin medications. Lasers Surg. Med. 42:113-122, 2010.

AB Background and Objective: We have developed a light-activated method called photochemical tissue bonding (PTB) for closing wounds using green light and a photosensitizing dye (Rose Bengal-RB) to initiate photochemical crosslinking of wound surface proteins. These studies were designed to determine whether RB causes phototoxicity during closure of skin incisions with PTB.
Study Design/Materials and Methods: RB phototoxicity was evaluated after sealing incisions in porcine skin ex 2 vivo and rabbit skin in vivo using PTB (1 mM RB, 100 J/cm(2), 532 nm, 0.3 or 0.5 W/cm(2).) Dead cells were identified by pyknotic nuclei and eosinophilic cytoplasm on H&E-stained sections. The influence on RB phototoxicity of penetration of RB into the wound wall (by confocal microscopy), RB concentration in the tissue (by extraction), and fluence of 532 nm reaching depths in skin (calculated from skin optical properties) were investigated.
Results: No significant differences were found in the percent dead cells in PTB-treated and control incisions in porcine skin at 24 hours or in rabbit skin at 2 hours and 3 and 7 days after surgery. RB was retained in a similar to 100 mu m wide band next to the Wound wall. The mean RB concentration within this band was 0.42 +/- 0.03 mM. Monte Carlo modeling of light distribution indicated that the fluence rate decreased from the subsurface peak to 0.5 W/cm(2) in the mid-dermis (similar to 350 mu m.) In vitro RB phototoxicity to dermal fibroblasts yielded an LD(50) of 0.50 +/- 0.09 J/cm(2) when the cells contained 0.46 nM RB.
Conclusions: PTB does not cause phototoxicity when used to repair skin wounds even though the RB concentration and 532 nm fluence in the mid-dermis during PTB are much greater than the LD50 for RB phototoxicity in vitro. These results indicate that phototoxicity is not a concern when using PTB for tissue repair. Lasers Surg. Med. 42:123-131, 2010. (C) 2009 Wiley-Liss, Inc.

AB The Dana-Farber Cancer Institute (DFCI) acute lymphoblastic leukemia (ALL) Consortium has been conducting multi-institutional clinical trials in childhood ALL since 1981. The treatment backbone has included 20-30 consecutive weeks of asparaginase during intensification and frequent vincristine/corticosteroid pulses during the continuation phase. Between 1985 and 2000, 1457 children aged 0-18 years were treated on four consecutive protocols: 85-01 (1985-1987), 87-01 (1987-1991), 91-01 (1991-1955) and 95-01 (1996-2000). The 10-year event-free survival (EFS) +/- s. e. by protocol was 77.9 +/- 2.8% (85-01), 74.2 +/- 2.3% (87-01), 80.8 +/- 2.1% (91-01) and 80.5 +/- 1.8% (95-01). Approximately 82% of patients treated in the 1980s and 88% treated in the 1990s were long-term survivors. Both EFS and overall survival (OS) rates were significantly higher for patients treated in the 1990s compared with the 1980s (P = 0.05 and 0.01, respectively). On the two protocols conducted in the 1990s, EFS was 79-85% for T-cell ALL patients and 75-78% for adolescents (age 10-18 years). Results of randomized studies revealed that dexrazoxane prevented acute cardiac injury without adversely affecting EFS or OS in high-risk (HR) patients, and frequently dosed intrathecal chemotherapy was an effective substitute for cranial radiation in standard-risk (SR) patients. Current studies continue to focus on improving efficacy while minimizing acute and late toxicities. Leukemia (2010) 24, 320-334; doi: 10.1038/leu.2009.253; published online 17 December 2009

AB Background
Treatment completion rates for hepatitis C virus (HCV) infection in clinical practice settings are unknown.
Methods
We assembled a national cohort of HCV-infected veterans-in-care from 1998 to 2003, using the VA National Patient Care Database for demographical/clinical information, Pharmacy Benefits Management database for pharmacy records and the Decision Support Systems database for laboratory data. We used logistic regression to determine the factors predicting treatment non-completion for HCV.
Results
We identified 134 934 HCV-infected veterans of whom 16 043 [11.9%; 95% confidence interval (CI) 11.7-12.1] were prescribed treatment for HCV. Among the 10 641 veterans with > 1 year of follow-up, 2396 (22.5%; 95% CI 21.7-23.3) completed a 48-week course. Non-completers were more likely to have pre-treatment anaemia, coronary artery disease, depression, substance abuse, used standard interferon, higher comorbidity count, and been treated at a low-volume treatment site (defined as sites initiating HCV treatment for < 200 individuals). In multivariable analyses, treatment completion was positively associated with pegylated interferon use [odds ratio (OR) 1.59, 95% CI 1.40-1.80] and site treatment volume (OR 1.87, 95% CI 1.56-2.24 for sites initiating treatment for > 200 individuals) and negatively associated with pre-treatment anaemia (OR 0.68, 95% CI 0.58-0.80 for haemoglobin 10-14 g/dl) and depression (OR 0.78, 95% CI 0.69-0.89). Human immunodeficiency virus coinfection and minority race were not associated with failing to complete treatment.
Conclusions
Among veterans-in-care with known HCV, 11.9% initiate therapy of whom 22.5% (one in 56 with known HCV infection) complete a 48-week course of treatment. Higher completion rates among higher volume treatment sites suggest that some factors associated with non-completion (pre-treatment depression and anaemia), may be modifiable with experience.

AB Whether pretransplant nonviral infections influence outcomes after transplantation in liver transplant recipients in the current era is not well defined. One hundred consecutive patients undergoing liver transplantation in 2005-2008 were studied. Demographics, posttransplant clinical events, and mortality were compared between recipients with and without infections within 12 months before transplantation. In all, 32% of the patients (32/100) developed 45 episodes of pretransplant infections, which included spontaneous bacterial peritonitis (35.6%), bloodstream infections (28.9%), cellulitis (13.3%), pneumonia (8.9%), urinary tract infections (6.7%), and other infections (6.7%). Compared with 68 recipients without pretransplant infections, those with infections had a higher Model for End-Stage Liver Disease score and a lower likelihood of transplantation from home and required longer and more frequent hospital care before and after transplantation (P < 0.05). Mortality at 90 (9.4% versus 2.9%) and 180 days (15.6% versus 10.3%) post-transplant did not differ significantly between recipients with and without pretransplant infections (P = not significant). A higher Model for End-Stage Liver Disease score (P < 0.05) and posttransplant infections (P < 0.05 and P < 0.001), but not pretransplant infections, were associated with posttransplant mortality at 90 and 180 days. In conclusion, pretransplant infections that have been adequately treated do not pose a significant risk for poor outcomes, including posttransplant mortality. Liver Transpl 16:222-228, 2010.

AB Factors contributing to increased risk for Alzheimer's disease (AD) include age, sex, genes, and family history of AD. Several risk factors for AD are endogenous; however, accumulating evidence implicates modifiable risk factors in the pathogenesis of AD. Although the continued task of identifying new genes will be critical to learning more about the disease, several research findings suggest that potentially alterable environmental factors influence genetic contributions, providing targets for disease prevention and treatment. Here, we review midlife risk factors for AD, and address the potential for therapeutic intervention in midlife. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

AB There is growing interest in the concept of network pharmacology, as opposed to specific pharmacological targets, as an important drug discovery paradigm. Also known as the "magic shotgun" paradigm, this strategy involves individual drugs interacting with multiple targets to achieve clinical benefit. Pharmacological promiscuity consistent with this paradigm has been suggested in vitro for antidepressants and anticonvulsants, which interact with many classes of ion channels (among other receptor targets). Although the link between certain "off-target" interactions and drug side effects is well-accepted, the potential linkage between promiscuity and clinical efficacy remains poorly understood. Here we summarize interactions of clinically useful anti-psychotic and anti-dementia medications with a diverse array of ligand- and voltage-gated ion channels. We hypothesize that promiscuous ion channel modulation may contribute to the efficacy of drugs used to treat psychosis and dementia. (C) 2009 Elsevier Ltd. All rights reserved.

AB We propose a technique to simultaneously estimate the local fiber orientations and perform multi-fiber tractography. Existing techniques estimate the local fiber orientation at each voxel independently so there is no running knowledge of confidence in the measured signal or estimated fiber orientation. Further, to overcome noise, many algorithms use a filter as a post-processing step to obtain a smooth trajectory. We formulate fiber tracking as causal estimation: at each step of tracing the fiber, the current estimate of the signal is guided by the previous. To do this, we model the signal as a discrete mixture of Watson directional functions and perform tractography within a filtering framework. Starting from a seed point, each fiber is traced to its termination using an unscented Kalman filter to simultaneously fit the signal and propagate in the most consistent direction. Despite the presence of noise and uncertainty, this provides an accurate estimate of the local structure at each point along the fiber. We choose the Watson function since it provides a compact representation of the signal parameterized by the principal diffusion direction and a scaling parameter describing anisotropy, and also allows analytic reconstruction of the oriented diffusion function from those parameters. Using a mixture of two and three components (corresponding to two-fiber and three-fiber models) we demonstrate in synthetic experiments that this approach reduces signal reconstruction error and significantly improves the angular resolution at crossings and branchings. In vivo experiments examine the corpus callosum and internal capsule and confirm the ability to trace through regions known to contain such crossing and branching while providing inherent path regularization.

TI Simultaneous navigation of multiple Pareto surfaces, with an application
to multicriteria IMRT planning with multiple beam angle configurations
SO MEDICAL PHYSICS
LA English

DE dosimetry; optimisation; radiation therapy
ID FLUENCE MAP OPTIMIZATION
AB Methods: The authors assume a convex optimization setting and represent the Pareto surface for each modality or given beam set by a set of discrete points on the surface. Weighted averages of these discrete points produce a continuous representation of each Pareto surface. The authors calculate a set of Pareto surfaces and use linear programming to navigate across the individual surfaces, allowing switches between surfaces. The switches are organized such that the plan profits in the requested way, while trying to keep the change in dose as small as possible.
Results: The system is demonstrated on a phantom pancreas IMRT case using 100 different five beam configurations and a multicriteria formulation with six objectives. The system has intuitive behavior and is easy to control. Also, because the underlying linear programs are small, the system is fast enough to offer real-time exploration for the Pareto surfaces of the given beam configurations.
Conclusions: The system presented offers a sound starting point for building clinical systems for multicriteria exploration of different modalities and offers a controllable way to explore hundreds of beam angle configurations in IMRT planning, allowing the users to focus their attention on the dose distribution and treatment planning objectives instead of spending excessive time on the technicalities of delivery.

AB vThe incidence of thyroid cancer has increased dramatically, yet the mortality has remained unchanged. There remain many challenges and "difficult problems" in diagnosing and treating patients with differentiated thyroid cancer (DTC). A significant percentage of patients with DTC will present with a thyroid nodule and an indeterminate fine needle aspiration biopsy underscoring the importance of proper evaluation and management. It is important when considering the extent of thyroidectomy and the management of lymph node metastases to balance the outcome of treatment-in terms of recurrence and mortality with the morbidity of the procedure. Total thyroidectomy and lymphadenectomy for macroscopic lymph node metastases appear to be the optimal therapy for most patients with DTC. Preservation of function is a priority in managing patients with DTC invading the recurrent laryngeal nerve, trachea, esophagus, or the larynx.

AB Aberrations in oncogenes and tumor suppressors frequently affect the activity of critical signal transduction pathways. To analyze systematically the relationship between the activation status of protein networks and other characteristics of cancer cells, we did reverse phase protein array (RPPA) profiling of the NCI60 cell lines for total protein expression and activation-specific markers of critical signaling pathways. To extend the scope of the study, we merged those data with previously published RPPA results for the NCI60. Integrative analysis of the expanded RPPA data set revealed five major clusters of cell lines and five principal proteomic signatures. Comparison of mutations in the NCI60 cell lines with patterns of protein expression showed significant associations for PTEN, PIK3CA, BRAF, and APC mutations with proteomic clusters. PIK3CA and PTEN mutation enrichment were not cell lineage-specific but were associated with dominant yet distinct groups of proteins. The five RPPA-defined clusters were strongly associated with sensitivity to standard anticancer agents. RPPA analysis identified 27 protein features significantly associated with sensitivity to paclitaxel. The functional status of those proteins was interrogated in a paclitaxel whole genome small interfering RNA ( siRNA) library synthetic lethality screen and confirmed the predicted associations with drug sensitivity. These studies expand our understanding of the activation status of protein networks in the NCI60 cancer cell lines, demonstrate the importance of the direct study of protein expression and activation, and provide a basis for further studies integrating the information with other molecular and pharmacological characteristics of cancer.

AB The most common test to identify latent tuberculosis is the tuberculin skin test that detects T cell responses of delayed type hypersensitivity type IV Since it produces false negative reactions in active tuberculosis or in high-risk persons exposed to tuberculosis patients as shown in this report, we studied antibody profiles to explain the anergy Of Such responses in high-risk individuals without active infection
Our results showed that humoral immunity against tuberculin, regardless of the result of the tuberculin skin test is important for protection from active tuberculosis and that the presence of high antibody titers is a more reliable indicator of infection latency suggesting that latency can be based on the levels of antibodies together with in vitro proliferation of peripheral blood mononuclear cells in the presence of the purified protein derivative Importantly, anti-tuberculin IgG antibody levels mediate the anergy described herein, which Could also prevent reactivation of disease in high-risk individuals with high antibody titers. Such anti-tuberculin IgG antibodies were also found associated with blocking and/or stimulation of in vitro cultures of PBMC with tuberculin In this regard. future studies need to establish if immune responses to Mycobacterium tuberculosis can generate a broad spectrum of reactions either toward Th1 responses favoring stimulation by cytokines or by antibodies and those toward diminished responses by Th2 cytokines or blocking by antibodies; possibly involving mechanisms of antibody dependent protection from Mtb by different subclasses of IgG Published by Elsevier Ltd.

AB Sphingolipids including sphingosine-1-phosphate and ceramide participate innumerous cell programs through signaling mechanisms. This class of lipids has important functions in stress responses; however, determining which sphingolipid mediates specific events has remained encumbered by the numerous metabolic interconnections of sphingolipids,such that modulating a specific lipid of interest through manipulating metabolic enzymes causes 'ripple effects', which change levels of many other lipids. Here, we develop a method of integrative analysis for genomic, transcriptomic, and lipidomic data to address this previously intractable problem. This method revealed a specific signaling role for phytosphingosine-1-phosphate, a lipid with no previously defined specific function in yeast, in regulating genes required for mitochondrial respiration through the HAP complex transcription factor. This approach could be applied to extract meaningful biological information from a similar experimental design that produces multiple sets of high-throughput data.

AB Oncolytic viral (OV) therapy is a promising therapeutic modality for brain tumors. Vasculostatin (Vstat120) is the cleaved and secreted extracellular fragment of brain-specific angiogenesis inhibitor 1 (BAI1), a brain-specific receptor. To date, the therapeutic efficacy of Vstat120 delivery into established tumors has not been investigated. Here we tested the therapeutic efficacy of combining Vstat120 gene delivery in conjunction with OV therapy. We constructed RAMBO (Rapid Antiangiogenesis Mediated By Oncolytic virus), which expresses Vstat120 under the control of the herpes simplex virus (HSV) IE4/5 promoter. Secreted Vstat120 was detected as soon as 4 hours postinfection in vitro and was retained for up to 13 days after OV therapy in subcutaneous tumors. RAMBO-produced Vstat120 efficiently inhibited endothelial cell migration and tube formation in vitro (P = 0.0005 and P = 0.0184, respectively) and inhibited angiogenesis (P = 0.007) in vivo. There was a significant suppression of intracranial and subcutaneous glioma growth in mice treated with RAMBO compared to the control virus, HSVQ (P = 0.0021 and P < 0.05, respectively). Statistically significant reduction in tumor vascular volume fraction (VVF) and microvessel density (MVD) was observed in tumors treated with RAMBO. This is the first study to report the antitumor effects of Vstat120 delivery into established tumors and supports the further development of RAMBO as a possible cancer therapy.

TI RNAi-mediated CCR5 Silencing by LFA-1-targeted Nanoparticles Prevents

AB RNA interference (RNAi)-mediated knockdown of gene expression offers a novel treatment strategy for human immunodeficiency virus (HIV) infection. However, the major hurdle for clinical use is a practical strategy for small interfering RNA (siRNA) delivery to the multiple immune cell types important in viral pathogenesis. We have developed a novel immunoliposome method targeting the lymphocyte function-associated antigen-1 (LFA-1) integrin expressed on all leukocytes and evaluated it for systemic delivery of siRNA in a humanized mouse model. We show that in vivo administration of the LFA-1 integrin-targeted and stabilized nanoparticles (LFA-1 I-tsNPs) results in selective uptake of siRNA by T cells and macrophages, the prime targets of HIV. Further, in vivo administration of anti-CCR5 siRNA/LFA-1 I-tsNPs resulted in leukocyte-specific gene silencing that was sustained for 10 days. Finally, humanized mice challenged with HIV after anti-CCR5 siRNA treatment showed enhanced resistance to infection as assessed by the reduction in plasma viral load and disease-associated CD4 T-cell loss. This study demonstrates the potential in vivo applicability of LFA-1-directed siRNA delivery as anti-HIV prophylaxis.

TI ROLE OF GELATINASES IN DISUSE-INDUCED SKELETAL MUSCLE ATROPHY

AB Gelatinases are a subgroup of the family of matrix metalloproteinases, which contains two members-gelatinase A and B. These enzymes play an important role in basement membrane homeostasis. Previous studies have associated basement membrane degradation with skeletal muscle atrophy. However, the specific contribution of gelatinases to the pathobiology of muscle atrophy remains unknown. In this study we examined the specific roles of gelatinase A and B in disuse-induced skeletal muscle atrophy using knockout mice. Although both gelatinase A and B are highly upregulated in disused muscle, only gelatinase A null mice had significantly reduced muscle atrophy as compared to wildtype littermates. Type IV collagen and laminin, two major components of basement membrane, were relatively well-preserved in disused muscle in gelatinase A null mice, but not in gelatinase B null mice. These findings suggest that gelatinase A, and not gelatinase B, plays a critical role in disuse-induced skeletal muscle atrophy. Muscle Nerve 41: 174-178, 2010

AB Levels of circulating glucose are tightly regulated. To identify new loci influencing glycemic traits, we performed meta-analyses of 21 genome-wide association studies informative for fasting glucose, fasting insulin and indices of beta-cell function (HOMA-B) and insulin resistance (HOMA-IR) in up to 46,186 nondiabetic participants. Follow-up of 25 loci in up to 76,558 additional subjects identified 16 loci associated with fasting glucose and HOMA-B and two loci associated with fasting insulin and HOMA-IR. These include nine loci newly associated with fasting glucose (in or near ADCY5, MADD, ADRA2A, CRY2, FADS1, GLIS3, SLC2A2, PROX1 and C2CD4B) and one influencing fasting insulin and HOMA-IR (near IGF1). We also demonstrated association of ADCY5, PROX1, GCK, GCKR and DGKB-TMEM195 with type 2 diabetes. Within these loci, likely biological candidate genes influence signal transduction, cell proliferation, development, glucose-sensing and circadian regulation. Our results demonstrate that genetic studies of glycemic traits can identify type 2 diabetes risk loci, as well as loci containing gene variants that are associated with a modest elevation in glucose levels but are not associated with overt diabetes.

AB Glucose levels 2 h after an oral glucose challenge are a clinical measure of glucose tolerance used in the diagnosis of type 2 diabetes. We report a meta-analysis of nine genome-wide association studies (n = 15,234 nondiabetic individuals) and a follow-up of 29 independent loci (n = 6,958-30,620). We identify variants at the GIPR locus associated with 2- h glucose level (rs10423928, beta (s.e.m.) = 0.09 (0.01) mmol/l per A allele, P = 2.0 x 10(-15)). The GIPR A-allele carriers also showed decreased insulin secretion (n = 22,492; insulinogenic index, P = 1.0 x 10(-17); ratio of insulin to glucose area under the curve, P = 1.3 x 10(-16)) and diminished incretin effect (n = 804; P = 4.3 x 10(-4)). We also identified variants at ADCY5 (rs2877716, P = 4.2 x 10(-16)), VPS13C (rs17271305, P = 4.1 x 10(-8)), GCKR (rs1260326, P = 7.1 x 10(-11)) and TCF7L2 (rs7903146, P = 4.2 x 10(-10)) associated with 2-h glucose. Of the three newly implicated loci (GIPR, ADCY5 and VPS13C), only ADCY5 was found to be associated with type 2 diabetes in collaborating studies (n = 35,869 cases, 89,798 controls, OR = 1.12, 95% CI 1.09-1.15, P = 4.8 x 10(-18)).

AB The electrocardiographic PR interval (or PQ interval) reflects atrial and atrioventricular nodal conduction, disturbances of which increase risk of atrial fibrillation. We report a meta-nalysis of genome-wide association studies for PR interval from seven population-based European studies in the CHARGE Consortium: AGES, ARIC, CHS, FHS, KORA, Rotterdam Study, and SardiNIA (N = 28,517). We identified nine loci associated with PR interval at P < 5 x 10(-8). At the 3p22.2 locus, we observed two independent associations in voltage-gated sodium channel genes, SCN10A and SCN5A. Six of the loci were near cardiac developmental genes, including CAV1-CAV2, NKX25 (CSX1), SOX5, WNT11, MEIS1, and TBX5-TBX3, providing pathophysiologically interesting candidate genes. Five of the loci, SCN5A, SCN10A, NKX2-5, CAV1-CAV2, and SOX5, were also associated with atrial fibrillation (N = 5,741 cases, P < 0.0056). This suggests a role for common variation in ion channel and developmental genes in atrial and atrioventricular conduction as well as in susceptibility to atrial fibrillation.

AB Scapuloperoneal spinal muscular atrophy (SPSMA) and hereditary motor and sensory neuropathy type IIC (HMSN IIC, also known as HMSN2C or Charcot-Marie-Tooth disease type 2C (CMT2C)) are phenotypically heterogeneous disorders involving topographically distinct nerves and muscles. We originally described a large New England family of French-Canadian origin with SPSMA and an American family of English and Scottish descent with CMT2C(1,2). We mapped SPSMA and CMT2C risk loci to 12q24.1-q24.31 with an overlapping region between the two diseases(3,4). Further analysis reduced the CMT2C risk locus to a 4-Mb region(5). Here we report that SPSMA and CMT2C are allelic disorders caused by mutations in the gene encoding the transient receptor potential cation channel, subfamily V, member 4 (TRPV4). Functional analysis revealed that increased calcium channel activity is a distinct property of both SPSMA- and CMT2C-causing mutant proteins. Our findings link mutations in TRPV4 to altered calcium homeostasis and peripheral neuropathies, implying a pathogenic mechanism and possible options for therapy for these disorders.

AB In atherosclerosis and Alzheimer's disease, deposition of the altered self components oxidized low-density lipoprotein (LDL) and amyloid-beta triggers a protracted sterile inflammatory response. Although chronic stimulation of the innate immune system is believed to underlie the pathology of these diseases, the molecular mechanisms of activation remain unclear. Here we show that oxidized LDL and amyloid-beta trigger inflammatory signaling through a heterodimer of Toll-like receptors 4 and 6. Assembly of this newly identified heterodimer is regulated by signals from the scavenger receptor CD36, a common receptor for these disparate ligands. Our results identify CD36-TLR4-TLR6 activation as a common molecular mechanism by which atherogenic lipids and amyloid-beta stimulate sterile inflammation and suggest a new model of TLR heterodimerization triggered by coreceptor signaling events.

AB Adjuvant chemotherapy for breast cancer after surgery has effectively lowered metastatic recurrence rates(1). However, a considerable proportion of women suffer recurrent cancer at distant metastatic sites despite adjuvant treatment. Identification of the genes crucial for tumor response to specific chemotherapy drugs is a challenge but is necessary to improve outcomes(2). By using integrated genomics, we identified a small number of overexpressed and amplified genes from chromosome 8q22 that were associated with early disease recurrence despite anthracycline-based adjuvant chemotherapy. We confirmed the association in an analysis of multiple independent cohorts. SiRNA-mediated knockdown of either of two of these genes, the antiapoptotic gene YWHAZ and a lysosomal gene LAPTM4B, sensitized tumor cells to anthracyclines, and overexpression of either of the genes induced anthracycline resistance. Overexpression of LAPTM4B resulted in sequestration of the anthracycline doxorubicin, delaying its appearance in the nucleus. Overexpression of these two genes was associated with poor tumor response to anthracycline treatment in a neoadjuvant chemotherapy trial in women with primary breast cancer. Our results suggest that 8q22 amplification and overexpression of LAPTM4B and YWHAZ contribute to de novo chemoresistance to anthracyclines and are permissive for metastatic recurrence. Overexpression of these two genes may predict anthracycline resistance and influence selection of chemotherapy.

AB Lung cancer is the leading cause of cancer death worldwide(1). Recent data suggest that tumor-associated inflammatory cells may modify lung tumor growth and invasiveness(2,3). To determine the role of neutrophil elastase (encoded by Elane) on tumor progression, we used the loxP-Stop-loxP K-ras(G12D) (LSL-K-ras) model of mouse lung adenocarcinoma(4) to generate LSL-K-ras-Elane(-/-) mice. Tumor burden was markedly reduced in LSL-K-ras-Elane(-/-) mice at all time points after induction of mutant K-ras expression. Kaplan-Meier survival analysis showed that whereas all LSL-K-ras-Elane(+/+) mice died, none of the mice lacking neutrophil elastase died. Neutrophil elastase directly induced tumor cell proliferation in both human and mouse lung adenocarcinomas by gaining access to an endosomal compartment within tumor cells, where it degraded insulin receptor substrate-1 (IRS-1). Immunoprecipitation studies showed that, as neutrophil elastase degraded IRS-1, there was increased interaction between phosphatidylinositol 3-kinase (PI3K) and the potent mitogen platelet-derived growth factor receptor (PDGFR), thereby skewing the PI3K axis toward tumor cell proliferation. The inverse relationship identified between neutrophil elastase and IRS-1 in LSL-K-ras mice was also identified in human lung adenocarcinomas, thus translating these findings to human disease. This study identifies IRS-1 as a key regulator of PI3K within malignant cells. Additionally, to our knowledge, this is the first description of a secreted proteinase gaining access to the inside of a cell and altering intracellular signaling.

AB Positioned nucleosomes limit the access of proteins to DNA and implement regulatory features encoded in eukaryotic genomes. Here we have generated the first genome-wide nucleosome positioning map for Schizosaccharomyces pombe and annotated transcription start and termination sites genome wide. Using this resource, we found surprising differences from the previously published nucleosome organization of the distantly related yeast Saccharomyces cerevisiae. DNA sequence guides nucleosome positioning differently: for example, poly(dA-dT) elements are not enriched in S. pombe nucleosome-depleted regions. Regular nucleosomal arrays emanate more asymmetrically-mainly codirectionally with transcription-from promoter nucleosome-depleted regions, but promoters harboring the histone variant H2A.Z also show regular arrays upstream of these regions. Regular nucleosome phasing in S. pombe has a very short repeat length of 154 base pairs and requires a remodeler, Mit1, that is conserved in humans but is not found in S. cerevisiae. Nucleosome positioning mechanisms are evidently not universal but evolutionarily plastic.

TI Overexpression of Elafin in Ovarian Carcinoma Is Driven by Genomic Gains

AB Ovarian cancer is a leading cause of cancer mortality in women. The aim of this study was to elucidate whether whey acidic protein (WAP) genes on chromosome 20q13.12, a region frequently amplified in this cancer, are expressed in serous carcinoma, the most common form of the disease. Herein, we report that a trio of WAP genes (HE4, SLPI, and Elafin) is overexpressed and secreted by serous ovarian carcinomas. To our knowledge, this is the first report linking Elafin to ovarian cancer. Fluorescence in situ hybridization analysis of primary tumors demonstrates genomic gains of the Elafin locus in a majority of cases. In addition, a combination of peptidomimetics, RNA interference, and chromatin immunoprecipitation experiments shows that Elafin expression can be transcriptionally upregulated by inflammatory cytokines through activation of the nuclear factor kappa B pathway. Importantly, using a clinically annotated tissue microarray composed of late-stage, high-grade serous ovarian carcinomas, we show that Elafin expression correlates with poor overall survival. These results, combined with our observation that Elafin is secreted by ovarian tumors and is minimally expressed in normal tissues, suggest that Elafin may serve as a determinant of poor survival in this disease.

AB Methods. The authors pooled individual-level cross-sectional data from 18 253 persons aged 28-100 years in four studies: the Cardiovascular Health Study; the Health, Aging and Body Composition Study; the Multi-Ethnic Study of Atherosclerosis and the Prevention of Renal and Vascular End-Stage Disease cohort. Kidney function was measured by cystatin C. Clinical risk factors for kidney disease included diabetes, hypertension, obesity, smoking, coronary heart disease, cerebrovascular disease, peripheral arterial disease and heart failure.
Results. Across the age range, there was a strong, non-linear association of age with cystatin C concentration. This association was substantial, even among participants free of clinical risk factors for kidney disease; mean cystatin C levels were 46% higher in participants 80 and older compared with those < 40 years (1.06 versus 0.72 mg/L, P < 0.001). Participants with one or more risk factors had higher cystatin C concentrations for a given age, and the age association was slightly stronger (P < 0.001 for age and risk factor interaction).
Conclusions. There is a strong, non-linear association of age with kidney function, even in healthy individuals. An important area for research will be to investigate the mechanisms that lead to deterioration of kidney function in apparently healthy persons.

AB Prior work has demonstrated that the memory dysfunction of Alzheimer's disease (AD) is accompanied by marked cortical pathology in medial temporal lobe (MTL) gray matter. In contrast, changes in white matter (WM) of pathways associated with the MTL have rarely been studied. We used diffusion tensor imaging (DTI) to examine regional patterns of WM tissue changes in individuals with AD. Alterations of diffusion properties with AD were found in several regions including parahippocampal WM, and in regions with direct and secondary connections to the MTL. A portion of the changes measured, including effects in the parahippocampal WM, were independent of gray matter degeneration as measured by hippocampal volume. Examination of regional changes in unique diffusion parameters including anisotropy and axial and radial diffusivity demonstrated distinct zones of alterations, potentially stemming from differences in underlying pathology, with a potential myelin specific pathology in the parahippocampal WM. These results demonstrate that deterioration of neocortical connections to the hippocampal formation results in part from the degeneration of critical MTL and associated fiber pathways.

AB The mechanism of status epilepticus-induced neuronal death in the immature brain is not fully understood. In the present study, we examined the contribution of caspases in our lithium-pilocarpine model of status epilepticus in 14 days old rat pups. In CA1, upregulation of caspase-8, but not caspase-9, preceded caspase-3 activation in morphologically necrotic cells. Pretreatment with a pan-caspase inhibitor provided neuroprotection, showing that caspase activation was not an epiphenomenon but contributed to neuronal necrosis. By contrast, upregulation of active caspase-9 and caspase-3, but not caspase-8, was detected in apoptotic dentate gyrus neurons. which were immunoreactive for doublecortin and calbindin-negative, two features of immature neurons. These results suggest that, in cells which are aligned in series as parts of the same excitatory hippocampal circuit, the same seizures induce neuronal death through different mechanisms. The regional level of neuronal maturity may be a determining factor in the execution of a specific death program. (c) 2009 Elsevier Inc. All rights reserved.

TI Comparison of Hematoma Shape and Volume Estimates in Warfarin Versus

ID ABC/2 ESTIMATION TECHNIQUE; ACTIVATED FACTOR-VII; ENLARGEMENT;
PREDICTORS; SCORE
AB Background Hematoma volume is a major determinant of outcome in patients with intracerebral hemorrhage (ICH). Accurate volume measurements are critical for predicting outcome and are thought to be more difficult in patients with oral anticoagulation-related ICH (OAT-ICH) due to a higher frequency of irregular shape. We examined hematoma shape and methods of volume assessment in patients with OAT-ICH.
Methods We performed a case-control analysis of a prospectively identified cohort of consecutive patients with ICH. We retrospectively reviewed 50 consecutive patients with OAT-ICH and 50 location-matched non-OAT-ICH controls. Two independent readers analyzed CT scans for hematoma shape and volume using both ABC/2 and ABC/3 methods. Readers were blinded to all clinical variables including warfarin status. Gold-standard ICH volumes were determined using validated computer-assisted planimetry.
Results Within this cohort, median INR in patients with OAT-ICH was 3.2. Initial ICH volume was not significantly different between non-OAT-ICH and OAT-ICH (35 +/- 38 cc vs. 53 +/- 56 cc, P = 0.4). ICH shape did not differ by anticoagulation status (round shape in 10% of OAT-ICH vs. 16% of non-OAT-ICH, P = 0.5). The ABC/3 calculation underestimated median volume by 9 (3-28) cc, while the ABC/2 calculation did so by 4 (0.8-12) cc.
Conclusions Hematoma shape was not statistically significantly different in patients with OAT-ICH. Among bedside approaches, the standard ABC/2 method offers reasonable approximation of hematoma volume in OAT-ICH and non-OAT-ICH.

Despite the relatively high prevelance of gastroparesis and functional dyspepsia, the aetiology and pathophysiology of these disorders remain incompletely understood. Similarly, the diagnostic and treatment options for these two disorders are relatively limited despite recent advances in our understanding of both disorders.
Purpose
This manuscript reviews the advances in the understanding of the epidemiology, pathophysiology, diagnosis, and treatment of gastroparesis and functional dyspepsia as discussed at a recent conference sponsored by the American Gastroenterological Association (AGA) and the American Neurogastroenterology and Motility Society (ANMS). Particular focus is placed on discussing unmet needs and areas for future research.

AB Oscillations in the gamma-band frequency range have been described to be more closely connected to hemodynamic changes as assessed with functional magnetic resonance imaging (fMRI) than other aspects of neuronal activity. In addition. gamma-band oscillations have attracted much interest during the last few years since they are thought to play a Crucial role in many aspects of brain function related to perception and cognition. It was the aim of the present simultaneous EEG-fMRI Study to identify brain regions specifically involved in the generation of the auditory gamma-band response (GBR) using single-trial coupling of EEG and fMRI. Ten healthy Subjects participated in this study Three different runs of an auditory choice reaction task with increasing difficulty were performed Brain activity was recorded simultaneously with high density FEG (61 channels) and fMRI (1.5 T). BOLD correlates of the GBR have been predicted using the sing-le-trial amplitude of the GBR
Reaction times (p<0.001). error rates (p<005) and self-ratings of task difficulty and effort demands (p<0.001) were related to the level of difficulty in the task In addition,we found a significant influence of task difficulty oil the amplitude of the GBR at Cz (p<0.05). Using single-trial Coupling of EEG and fMRI GBR-specific activations were found only in the auditory cortex, the thalamus and the anterior cingulate cortex (ACC) in the most difficult run. Single-trial coupling might be a useful method in order to increase our knowledge about the functional neuroanatomy of "neural ensembles" coupled by 40 Hz oscillations (C) 2009 Elsevier Inc.

AB Pain and somatosensory processing involves an interaction of multiple neuronal networks One result Of these complex interactions is the presence of differential responses across brain regions that may be incompletely modeled by a straightforward application of standard general linear model (GLM) approaches based solely on the applied stimulus We examined temporal blood oxygenation-level dependent (BOLD) signatures elicited by two Stimulation paradigms (brush and hear) providing innocuous and noxious stimuli Data were acquired from 32 healthy male subjects (2 independent cohorts) Regional time courses and model-free analyses of the first cohort revealed distinct temporal features of the BOLD responses elicited during noxious versus innocuous Stimulation Specifically. a biphasic (dual peak) BOLD signal was observed in response to heat but much less so in response to brush Stimuli This signal was characterized by a stimulus-locked response along with a second peak delayed by similar to 12.5 s A cross-validation error analysis determined a modified design matrix comprising two explanatory variables (EVs) as a parsimonious means to model the biphasic responses within a GLM framework. One EV was directly derived from the stimulation paradigm (EVI), while the second EV (EV2) was EVI shifted by 12 5 s. The 2EV GLM analysis enabled a more detailed characterization of the elicited BOLD responses. particularly during pain processing This was confirmed by application of the model to a second. independent cohort[ALI] Further more, the delayed component of the biphasic response was strongly associated with the noxious heat stimuli. suggesting that this may represent a sensitive fMRI link of pain processing (C) 2009 Elsevier Inc All rights reserved

AB The analysis of fMRI data is challenging because they consist generally of a relatively modest signal contained in a high-dimensional space: a single scan can contain millions of voxel recordings over space and time We present a method for classification and discrimination among fMRI that is based on modeling the scans as distance matrices, where each matrix measures the divergence of spatial network signals that fluctuate over time. We used single-subject independent components analysis (ICA). decomposing an fMRI scan into a set of statistically independent spatial networks, to extract spatial networks and time courses front each Subject unique relationship with the other components within that Subject Mathematical properties of that have these relationships reveal information about the infrastructure of the brain by measuring the interaction between and strength of the components Our technique IS unique, in that it does not require spatial alignment of the scans across subjects Instead, the classifications are made solely on the temporal activity taken by the subject's unique ICs. Multiple scans are not required and multivariate classification is implementable, and the algorithm is effectively blind to the subject-uniform underlying task paradigm Classification accuracy of Lip to 90% was realized on a resting-scanned schizophrenia/normal dataset and a tasked multivariate Alzheimer's/old/young dataset We propose that the ICs represent a plausible set of imaging basis functions consistent with network-driven theories Of Mural activity in which the observed signal is an aggregate of independent spatial networks having possibly dependent temporal activity (C) 2009 Elsevier Inc.

AB Neurologic complications affect posttransplant recovery of more than 20% of transplant recipients. Etiology is usually related to surgical procedure of transplantation, primary disorders causing failure of transplanted organ, opportunistic infections, and neurotoxicity of immunosuppressive medications. Risk of opportunistic infections and immunosuppressant neurotoxicity is greatest within the first six months, but it persists along with long-term maintenance immunosuppression required to prevent graft rejection. Neurotoxicity may require alteration of immunosuppressive regimen, and prompt therapy of opportunistic infections improves outcomes.

AB Glucocorticoids are beneficial in many muscular dystrophies but they are ineffective in treating dysferlinopathy, a rare muscular dystrophy caused by loss of dysferlin. We sought to understand the molecular basis for this disparity by studying the effects Of a glucocorticoid on differentiation of the myoblast cell line, C2C12, and dysferlin-deficient C2C12s. We found that pharmacologic doses of dexamethasone enhanced the myogenic fusion efficiency of C2C12s and increased the induction of dysferlin, along with specific myogenic transcription factors, sarcolemmal and structural proteins. In contrast, the dysferlin-deficient C2C12 cell line demonstrated a reduction in long myotubes and early induction of particular muscle differentiation proteins, most notably, myosin heavy chain. Dexamethasone partially reversed the defect in myogenic fusion in the dysferlin-deficient C2C12 cells. We hypothesize that a key therapeutic benefit Of glucocorticoids may be the up-regulation of dysferlin as an important component of glucocorticoid-enhanced myogenic differentiation.

AB Exposure to cocaine during the fetal period can produce significant lasting changes in the structure and function of the brain. Cocaine exerts its effects on the developing brain by blocking monoamine transporters and impairing monoamine receptor signaling. Dopamine is a major central target of cocaine. In a mouse model, we show that cocaine exposure from embryonic day 8 (E8) to EA produces significant reduction in dopamine transporter activity, attenuation of dopamine D1-receptor function and upregulation of dopamine D2-receptor function. Cocaine's effects on the D1-receptor are at the level of protein expression as well as activity. The cocaine exposure also produces significant increases in basal cAMP levels in the striatum and cerebral cortex. The increase in the basal cAMP levels was independent of dopamine receptor activity. In contrast, blocking the adenosine A2a receptor down regulated the basal CAMP levels in the cocaine-exposed brain to physiological levels, suggesting the involvement of adenosine receptors in mediating cocaine's effects on the embryonic brain. In support of this suggestion, we found that the cocaine exposure downregulated adenosine transporter function. We also found that dopamine D2- and adenosine A2a-receptors antagonize each other's function in the embryonic brain in a manner consistent with their interactions in the mature brain. Thus, our data show that prenatal cocaine exposure produces direct effects on both the dopamine and adenosme systems. Furthermore, the dopamine D2 and adenosine A2a receptor interactions in the embryonic brain discovered in this study unveil a novel substrate for cocaine's effects on the developing brain.

AB While bupropion HCl and practical group counseling (PGC) are commonly used treatments for tobacco dependence, the effects of these treatments on brain function are not well established. For this study, 54 tobacco-dependent cigarette smokers underwent resting (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) scanning before and after 8 weeks of treatment with bupropion HCl, PGC, or pill placebo. Using Statistical Parametric Mapping (SPM 2), changes in cerebral glucose metabolism from before to after treatment were compared between treatment groups and correlations were determined between amount of daily cigarette usage and cerebral glucose metabolism. Compared with placebo, the two active treatments (bupropion HCl and PGC) had reductions in glucose metabolism in the posterior cingulate gyrus. Further analysis suggested that PGC had a greater effect than bupropion HCl on glucose metabolism in this region. We also found positive correlations between daily cigarette use and glucose metabolism in the left occipital gyrus and parietal-temporal junction. There were no significant negative correlations between daily cigarette use and glucose metabolism. Our findings suggest that bupropion HCl and PGC reduce neural activity much as the performance of a goal-oriented task does in the default mode network of the brain, including the posterior cingulate gyrus. Thus, this study supports the theory that active treatments for tobacco dependence move the brain into a more goal-oriented state.

AB Background: In August 2007, the President's Cancer Panel urged the leadership of the nation to "summon the political will to address the public health crisis caused by tobacco use" (President's Cancer Panel, N, 2007, Promoting healthy lifestyles: Policy, program, and personal recommendations for reducing cancer risk. http://deainfo.nci.nih.gov/advisory/pcp/pcp07rpt/pcp07rpt.pdf). While some research has examined predictors of public support for tobacco control measures, little research has examined modifiable factors that may influence public attitudes toward tobacco control.
Methods: We used the American Legacy Foundation's 2003 American Smoking and Health Survey 2 to examine the contribution of smoking status, knowledge of the negative effects of tobacco, and tobacco-specific media exposure (antitobacco messages, news coverage of tobacco issues, and protobacco advertising) on U. S. adults' attitudes toward tobacco control. In addition, we assessed whether smoking status moderates the relationship between tobacco-specific media exposure and policy attitudes. Weighted multivariable logistic regression models were employed.
Results: Results suggest that knowledge of the negative effects of tobacco and smoking status are associated with attitudes toward tobacco control and that exposure to tobacco-specific information in the media plays a role only in some instances. We found no evidence of effect modification by smoking status on the impact of exposure to tobacco-specific media on attitudes toward tobacco control.
Discussion: Understanding the impact of readily modifiable factors that shape policy attitudes is essential if we are to target outreach and education in a way that is likely to sway public support for tobacco control.

AB Introduction: Emerging research suggests potential effects of the menstrual cycle on various aspects of smoking behavior in women, but results to date have been mixed. The present study sought to explore the influence of menstrual cycle phase on reactivity to smoking in vivo and stressful imagery cues in a sample of non-treatment-seeking women smokers.
Methods: Via a within-subjects design, nicotine-dependent women (N = 37) participated in a series of four cue reactivity sessions, each during a distinct biologically verified phase of the menstrual cycle (early follicular [EF], mid-follicular [MF], midluteal [ML], and late luteal [LL]). Subjective (Questionnaire of Smoking Urges-Brief; QSU-B) and physiological (skin conductance and heart rate) measures of craving and reactivity were collected and compared across phases.
Results: Subjective reactive craving (QSU-B) to smoking in vivo cues varied significantly across the menstrual cycle (p = .02) and was higher in both EF and MF phases versus ML and LL phases, but this finding was not sustained when controlling for reactivity to neutral cues. Heart rate reactivity to stressful imagery cues (p = .01) and skin conductance reactivity to smoking in vivo cues (p = .05) varied significantly across the menstrual cycle upon controlling for reactivity to neutral cues, with highest reactivity during the MF phase.
Discussion: Menstrual cycle phase may have an effect on reactivity to smoking-related and stressful cues among women smokers. These findings contribute to an expanding literature, suggesting menstrual cycle effects on smoking behaviors in women.

AB The quality of an RF detector coil design is commonly judged on how it compares with other coil configurations. The aim of this article is to develop a tool for evaluating the absolute performance of RF coil arrays. An algorithm to calculate the ultimate intrinsic signal-to-noise ratio (SNR) was implemented for a spherical geometry. The same imaging tasks modeled in the calculations were reproduced experimentally using a 32-element head array. Coil performance maps were then generated based on the ratio of experimentally measured SNR to the ultimate intrinsic SNR, for different acceleration factors associated with different degrees of parallel imaging. The relative performance in all cases was highest near the center of the samples (where the absolute SNR was lowest). The highest performance was found in the unaccelerated case and a maximum of 85% was observed with a phantom whose electrical properties are consistent with values in the human brain. The performance remained almost constant for 2-fold acceleration, but deteriorated at higher acceleration factors, suggesting that larger arrays are needed for effective highly-accelerated parallel imaging. The method proposed here can serve as a tool for the evaluation of coil designs, as well as a tool to guide the development of original designs which may begin to approach the optimal performance.

AB The multi-pixel photon counter (MPPC) or silicon photomultiplier (SiPM), recently introduced as a solid-state photodetector, consists of an array of Geiger-mode photodiodes (microcells). It is a promising device for PET due to its potential for high photon detection efficiency (PDE) and its foreseeable immunity to magnetic fields. It is also easy to use with simple read-outs, has a high gain and a small size. In this work we evaluate the in field performance of three I X I mm(2) (With 100, 400 and 1600 microcells, respectively) and one 6 x 6 mm(2) (arranged as a 2 x 2 array) Hamamatsu MPPCs for their use in PET imaging. We examine the dependence of the energy resolution and the gain of these devices on the temperature and reverse bias voltage, when coupled to LYSO scintillator crystals under conditions that one would find in a PET system. We find that the 400 and 1600 microcells models and the 2 x 2 array are suitable for small-size crystals, like those employed in high resolution small animal scanners. We have confirmed the good performance of these devices up to magnetic fields of 7T as well as their suitability for performing PET acquisitions in the presence of fast switching gradients and high duty radiofrequency MRI sequences.

AB OBJECTIVE: To estimate whether prolapse severity is a major contributor to urinary incontinence severity, as measured by validated incontinence questionnaires.
METHODS: We analyzed data from two large female stress urinary incontinence (SUI) surgical cohorts: the Stress Incontinence Surgical Treatment Efficacy Trial (SISTEr) study (N=655) and the subsequent Trial of Mid-Urethral Slings (TOMUS) study (N=597). All participants completed a standardized baseline assessment including validated measures of symptom severity, quality of life, objective measures of urine loss (Urogenital Distress Inventory [UDI], Medical, Epidemiologic, and Social Aspects of Aging questionnaire, Incontinence Impact Questionnaire, and pad test), as well as the Pelvic Organ Prolapse Quantification assessment. Groups were compared using the) chi(2); test (categorical measures) or the one-way analysis of variance (continuous measures). Statistical significance was defined as P<.05.
RESULTS: The SISTEr and TOMUS samples were similar for many variables including age (52 and 53 years, respectively), nulliparity (9% and 12%), prior urinary incontinence (UI) surgery (14% and 13%), and prior hysterectomy (31% and 28%), but other differences necessitated separate analysis of the two cohorts. There was not a statistically significant difference in UDI scores according to prolapse stage in either study population. Patients with prior surgery for pelvic organ prolapse and SUI had more incontinence symptoms and were more bothered by their UI regardless of prolapse stage.
CONCLUSION: Prolapse stage is not strongly or consistently associated with incontinence severity in women who select surgical treatment of SUI. Prior pelvic organ prolapse and UI surgery is associated with worse UI severity and bother.

AB Acute exacerbations of chronic obstructive pulmonary disease (COPD) are a major source of morbidity and contribute significantly to healthcare costs. Although bacterial infections are implicated in nearly 50% of exacerbations, only a handful of pathogens have been consistently identified in COPD airways, primarily by culture-based methods, and the bacterial microbiota in acute exacerbations remains largely uncharacterized. The aim of this study was to comprehensively profile airway bacterial communities using a culture-independent microarray, the 16S rRNA PhyloChip, of a cohort of COPD patients requiring ventilatory support and antibiotic therapy for exacerbation-related respiratory failure. PhyloChip analysis revealed the presence of over 1,200 bacterial taxa representing 140 distinct families, many previously undetected in airway diseases; bacterial community composition was strongly influenced by the duration of intubation. A core community of 75 taxa was detected in all patients, many of which are known pathogens. Bacterial community diversity in COPD airways is substantially greater than previously recognized and includes a number of potential pathogens detected in the setting of antibiotic exposure. Comprehensive assessment of the COPD airway microbiota using high-throughput, culture-independent methods may prove key to understanding the relationships between airway bacterial colonization, acute exacerbation, and clinical outcomes in this and other chronic inflammatory airway diseases.

AB Proteomic profiling by mass spectrometry has tremendous potential for identifying disease biomarkers. A key limitation of mass spectrometry is that the information provided on the abundance of the various peptides is only relative. Thus, normalization is typically employed. Several normalization methods have been proposed and implemented in the literature. However, it is not clear if there is any reason to prefer one method over another. The goal of this study was to investigate the effect of normalization strategy on the identification of putative biomarkers from MALDI-TOF and SELDI-TOF mass spectra. Our results demonstrate that many of the putative biomarkers identified by mass spectrometry will be the same regardless of which data normalization scheme is applied. However, there can be substantial differences in the m/z values identified as being most discriminatory based on choice of normalization method. As there is no consistent pattern as to which normalization method yields the most promising targets for follow up study, we recommend that investigators routinely repeat their analysis with multiple normalization methods and consider the top several candidates identified in each case.

AB Objective: Evaluate the effectiveness of an interactive cognitive computer simulation for teaching the hydrodissection portion of cataract surgery compared with standard teaching and to assess the attitudes of residents about the teaching tools and their perceived confidence in the knowledge gained after using the tools.
Design: Case-control study.
Participants and Controls: Residents at academic institutions.
Methods: Prospective, multicenter, single-masked, controlled trial was performed in 7 academic departments of ophthalmology (Harvard Medical School/Massachusetts Eye and Ear Infirmary, University of Iowa, Emory University, University of Cincinnati, University of Pennsylvania/Scheie Eye Institute, Jefferson Medical College of Thomas Jefferson University/Wills Eye Institute, and the Aravind Eye Institute). All residents from these centers were asked to participate and were randomized into 2 groups. Group A (n = 30) served as the control and received traditional teaching materials; group B (n = 38) received a digital video disc of the Virtual Mentor program. This program is an interactive cognitive simulation, specifically designed to separate cognitive aspects (such as decision making and error recognition) from the motor aspects. Both groups took online anonymous pretests (n = 68) and posttests (n = 58), and answered satisfaction questionnaires (n = 53). Wilcoxon tests were completed to compare pretest and posttest scores between groups. Analysis of variance was performed to assess differences in mean scores between groups.
Main Outcome Measures: Scores on pretests, posttests, and satisfaction questionnaires.
Results: There was no difference in the pretest scores between the 2 groups (P = 0.62). However, group B (Virtual Mentor [VM]) scored significantly higher on the posttest (P = 0.01). Mean difference between pretest and posttest scores were significantly better in the VM group than in the traditional learning group (P = 0.04). Questionnaire revealed that the VM program was "more fun" to use (24.1% vs 4.2%) and residents were more likely to use this type of program again compared with the likelihood of using the traditional tools (58.6% vs 4.2%).
Conclusions: The VM, a cognitive computer simulation, augmented teaching of the hydrodissection step of phacoemulsification surgery compared with traditional teaching alone. The program was more enjoyable and more likely to be used repetitively by ophthalmology residents.

AB Purpose: To evaluate the outcomes of cyclophosphamide therapy for noninfectious ocular inflammation.
Design: Retrospective cohort study.
Participants: Two hundred fifteen patients with noninfectious ocular inflammation observed from initiation of cyclophosphamide.
Methods: Patients initiating cyclophosphamide, without other immunosuppressive drugs (other than corticosteroids), were identified at 4 centers. Dose of cyclophosphamide, response to therapy, corticosteroid-sparing effects, frequency of discontinuation, and reasons for discontinuation were obtained by medical record review of every visit.
Main Outcome Measures: Control of inflammation, corticosteroid-sparing effects, and discontinuation of therapy.
Results: The 215 patients (381 involved eyes) meeting eligibility criteria carried diagnoses of uveitis (20.4%), scleritis (22.3%), ocular mucous membrane pemphigoid (45.6%), or other forms of ocular inflammation (11.6%). Overall, approximately 49.2% (95% confidence interval [CI], 41.7%-57.2%) gained sustained control of inflammation (for at least 28 days) within 6 months, and 76% (95% CI, 68.3%-83.7%) gained sustained control of inflammation within 12 months. Corticosteroid-sparing success (sustained control of inflammation while tapering prednisone to 10 mg or less among those not meeting success criteria initially) was gained by 30.0% and 61.2% by 6 and 12 months, respectively. Disease remission leading to discontinuation of cyclophosphamide occurred at the rate of 0.32/person-year (95% CI, 0.24-0.41), and the estimated proportion with remission at or before 2 years was 63.1% (95% CI, 51.5%-74.8%). Cyclophosphamide was discontinued by 33.5% of patients within 1 year because of side effects, usually of a reversible nature.
Conclusions: The data suggest that cyclophosphamide is effective for most patients for controlling inflammation and allowing tapering of systemic corticosteroids to 10 mg prednisone or less, although 1 year of therapy may be needed to achieve these goals. Unlike with most other immunosuppressive drugs, disease remission was induced by treatment in most patients who were able to tolerate therapy. To titrate therapy properly and to minimize the risk of serious potential side effects, a systematic program of laboratory monitoring is required. Judicious use of cyclophosphamide seems to be beneficial for severe ocular inflammation cases where the potentially vision-saving benefits outweigh the substantial potential side effects of therapy, or when indicated for associated systemic inflammatory diseases.

AB Purpose: To evaluate the risk of and risk factors for hypopyon among patients with uveitis and to evaluate the risk of visual changes and complications after hypopyon.
Design: Retrospective cohort study.
Participants: Patients with uveitis at 4 academic ocular inflammation subspecialty practices.
Methods: Data were ascertained by standardized chart review.
Main Outcome Measures: Prevalence and incidence of hypopyon, risk factors for hypopyon, and incidence of visual acuity changes and ocular complications after hypopyon.
Results: Among 4911 patients with uveitis, 41 (8.3/1000) cases of hypopyon were identified at the time of cohort entry. Of these, 2885 initially free of hypopyon were followed over 9451 person-years, during which 81 patients (2.8%) developed hypopyon (8.57/1000 person-years). Risk factors for incident hypopyon included Behcet's disease (adjusted relative risk [RR] = 5.30; 95% confidence interval [CI], 2.76-10.2), spondyloarthropathy (adjusted RR = 2.86; 95% CI, 1.48-5.52), and human leukocyte antigen (HLA)-B27 positivity (adjusted RR = 2.04; 95% CI, 1.17-3.56). Patients with both a spondyloarthropathy and HLA-B27 had a higher risk than either factor alone (crude RR = 4.39; 95% CI, 2.26-8.51). Diagnosis of intermediate uveitis (+/- anterior uveitis) was associated with a lower risk of hypopyon (with respect to anterior uveitis only, adjusted RR = 0.35; 95% CI, 0.15-0.85). Hypopyon incidence tended to be lower among patients with sarcoidosis (crude RR = 0.22; 95% CI, 0.06-0.90; adjusted RR = -0.28; 95% CI, 0.07-1.15). Post-hypopyon eyes and eyes not developing hypopyon had a similar incidence of band keratopathy, posterior synechiae, ocular hypertension, hypotony, macular edema, epiretinal membrane, cataract surgery, or glaucoma surgery. Post-hypopyon eyes were more likely than eyes not developing hypopyon to gain 3 lines of vision (crude RR = 1.54; 95% CI, 1.05-2.24) and were less likely to develop 20/200 or worse visual acuity (crude RR = 0.41; 95% CI, 0.17-0.99); otherwise, visual outcomes were similar in these groups.
Conclusions: Hypopyon is an uncommon occurrence in patients with uveitis. Risk factors included Behcet's disease, HLA-B27 positivity, and spondyloarthropathy. Intermediate uveitis cases (+/- anterior uveitis) had a lower risk of hypopyon. On average, post-hypopyon eyes were no more likely than other eyes with uveitis to develop structural ocular complications or lose visual acuity.

AB Absolute measurements of cerebral blood flow (CBF) are an important endpoint in studies of cerebral pathophysiology. Currently no accepted method exists for in vivo longitudinal monitoring of CBF with high resolution in rats and mice. Using three-dimensional Doppler Optical Coherence Tomography and cranial window preparations, we present methods and algorithms for regional CBF measurements in the rat cortex. Towards this end, we develop and validate a quantitative statistical model to describe the effect of static tissue on velocity sensitivity. This model is used to design scanning protocols and algorithms for sensitive 3D flow measurements and angiography of the cortex. We also introduce a method of absolute flow calculation that does not require explicit knowledge of vessel angles. We show that OCT estimates of absolute CBF values in rats agree with prior measures by autoradiography, suggesting that Doppler OCT can perform absolute flow measurements in animal models.

AB Quantitative measurement of diffusive and directional processes of intracellular structures is not only critical in understanding cell mechanics and functions, but also has many applications, such as investigation of cellular responses to therapeutic agents. We introduce a label-free optical technique that allows non-perturbative characterization of localized intracellular dynamics. The method combines a field-based dynamic light scattering analysis with a confocal interferometric microscope to provide a statistical measure of the diffusive and directional motion of scattering structures inside a microscopic probe volume. To demonstrate the potential of this technique, we examined the localized intracellular dynamics in human epithelial ovarian cancer cells. We observed the distinctive temporal regimes of intracellular dynamics, which transitions from random to directional processes on a timescale of similar to 0.01 sec. In addition, we observed disrupted directional processes on the timescale of 1 similar to 5 sec by the application of a microtubule polymerization inhibitor, Colchicine, and ATP depletion.

AB The highly diffuse nature of light propagation in biological tissue is a major challenge for obtaining high-fidelity fluorescence tomographic images. In this work we investigated the use of time-gated detection of early-arriving photons for reducing the effects of light scatter in mice relative to quasi-cw photons. When analyzing sinographic representations of the measured data, it was determined that early photons allowed a reduction in the measured FWHM of fluorescent targets by a factor of approximately 2-3, yielding a significant improvement in the tomographic image reconstruction quality.

AB Objectives. To define, for the C5.18 chondrocyte-restricted rat cell line, (1) the capacities for recognition of alternatively spliced segments of the adhesion protein fibronectin (FN), (2) the integrin subunits required for such recognition, and (3) differences in such FN recognition vs the multipotential chondroprogenitor line, RCJ 3 1
Methods C5 18 and RCJ 3 1 cells were tested for their capacities to adhere to recombinant alternatively spliced segments of rat FN, presented on plastic surfaces either in isolation or in partial FNs spanning the 7th through 15th type III repeats (III7-15 FNs) The effects on such adhesion of cations and integrin subunit-specific antibodies were tested
Results Despite significant augmentation in chondrocyte-specific gene expression in C5.18 relative to the RCJ 3 1 cells, the two lines exhibited similar recognition of FN spliced segments and partial isoforms Specifically, both lines adhered to the extra type III repeat A (EIIIA) and V, but not extra type III repeat B (EIIIB), segments There were different cation and integrin subunit requirements for adhesion to EIIIA vs V segments, and only the V segment was recognized in the context of a III7-15 FN Such recognition was mediated via a "second" arginineglycine-aspartic acid (RGD) sequence that is present in the V95 subsegment in rat, but not human, FN
Conclusion The chondrocyte lineage-committed C5 18 cell line, similar to its multipotential chondroprogenitor, RCJ 3 1, recognizes the "cartilage-restricted" EIIIA and V segments of FN with cation, integrin, and molecular context requirements that are specific to each of these segments Published by Elsevier Ltd on behalf of Osteoarthritis Research Society International

AB OBJECTIVE: Hearing loss is the most common sensory disorder in the United States, afflicting more than 36 million people. Higher intakes of vitamins C, E, beta carotene, B12, and folate have been proposed to reduce the risk of hearing loss.
STUDY DESIGN: We prospectively evaluated the association between intake from foods and supplements of vitamins C, E, beta carotene, B12, and folate, and the incidence of hearing loss.
SETTING: Health Professionals Follow-up Study.
SUBJECTS AND METHODS: A total of 26,273 men aged 40 to 74 years at baseline in 1986. Participants completed questionnaires about lifestyle and medical history every two years and diet every four years. Information on self-reported professionally diagnosed hearing loss and year of diagnosis was obtained from the 2004 questionnaire, and cases were defined as hearing loss diagnosed between 1986 and 2004. Cox proportional hazards multivariate regression was used to adjust for potential confounders.
RESULTS: There were 3559 cases of hearing loss identified. Overall, there was no significant association between vitamin intake and risk of hearing loss. Among men aged 60 years, total folate intake was associated with a reduced risk of hearing loss; the relative risk for men aged >= 60 years old in the highest quintile compared with the lowest quintile of folate intake was 0.79 (95% confidence interval 0.65-0.96).
CONCLUSIONS: Higher intake of vitamin C, E, beta carotene, or B12 does not reduce the risk of hearing loss in adult males. Men aged years may benefit from higher folate intake to reduce the risk of developing hearing loss. (C) 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation. All rights reserved.

AB The majority of neuroimaging studies on pain focuses on the study of BOLD activations, and more rarely on deactivations. In this study, in a relatively large cohort of subjects (N = 61), we assess (a) the extent of brain activation and deactivation during the application of two different heat pain levels (HIGH and LOW) and (b) the relations between these two directions of fMRI signal change. Furthermore, in a subset of our subjects (N = 12), we assess (c) the functional connectivity of pain-activated or -deactivated regions during resting states. As previously observed, we find that pain stimuli induce intensity dependent (HIGH pain > LOW pain) fMRI signal increases across the pain matrix. Simultaneously, the noxious stimuli induce activity decreases in several brain regions, including some of the 'core structures' of the default network (DMN). In contrast to what we observe with the signal increases, the extent of deactivations is greater for LOW than HIGH pain stimuli. The functional dissociation between activated and deactivated networks is further supported by correlational and functional connectivity analyses. Our results illustrate the absence of a linear relationship between pain activations and deactivations, and therefore suggest that these brain signal changes underlie different aspects of the pain experience.

AB Background. Escherichia coli asparaginase is an important component of treatment for childhood acute lymphoblastic leukemia (ALL); however, hypersensitivity develops in up to 30% of patients. We assessed the nadir enzyme activity and tolerability of Erwinia asparaginase, an alternative preparation, in E. coli asparaginase-allergic patients. Patients and Methods. Between 2000 and 2002, 215 children with newly diagnosed ALL were enrolled on Dana-Farber Cancer Institute ALL Consortium Protocol 00-01 and were to receive 30 weekly doses of intramuscular E. coli asparaginase. If E. coli asparaginase allergy developed, patients were switched to twice-weekly intramuscular Erwinia asparaginase (25,000 IU/m(2)). Nadir serum asparaginase activity (NSAA) was measured every 3 weeks. Results. Forty-two patients (20%) developed E. coli asparaginase allergy and switched to Erwinia. Of 38 patients with evaluable samples, 34 (89%) Erwinia-treated patients had at least one therapeutic NSAA (>= 0.1 IU/ml). The median NSAA was 0.247 IU/ml 3 days and 0.077 IU/ml 4 days after an Erwinia dose. Associated toxicities included allergy in 14 (33%) and pancreatitis in 3 patients (7%). At a median follow-up of 5.4 years, event-free survival (+/- standard error) of the 42 patients who switched to Erwinia was 86 +/- 5% compared with 81 +/- 3% for the 170 patients without E. coli asparaginase allergy (P=0.55). Conclusions. Twice-weekly Erwinia asparaginase was well tolerated and achieved a therapeutically effective NSAA in most E. coli asparaginase-allergic patients. Development of E. coli allergy and subsequent treatment with twice-weekly Erwinia did not adversely impact event-free Survival. Erwinia asparaginase Should be considered for E. coli asparaginase-allergic patients. Pediatr Blood Cancer 2010;54:199-205. (C) 2009 Wiley-Liss, Inc.

AB Background. Sideroblastic anemias are heterogeneous congenital and acquired bone marrow disorders characterized by pathologic iron deposits in mitochondria of erythroid precursors. Among the congenital sideroblastic anemias (CSAs), the most common form is X-linked sideroblastic anemia, due to Mutations in 5-aminolevulinate synthase (ALAS2). A novel autosomal recessive CSA, caused by mutations in the erythroid specific mitochondrial transporter SLC25A38, was recently defined. Other known etiologies include mutations in genes encoding the thiamine transporter SLC19A2, the RNA-modifying enzyme pSeLldouridine synthase 1 (PUS1), a mitochondrial ATP-binding cassette transporter (ABCB7), glutaredoxin 5 (GLRX5), as well as mitochondrial DNA deletions. Despite these known diverse causes, in a Substantial portion of CSA cases a presumed genetic defect remains unknown. Procedure. In the context of the recent discovery of SLC25A38 as a major novel cause, we systematically analyzed a large cohort of previously unreported CSA patients. Sixty CSA probands (28 females, 32 males) were examined for ALAS2, SLC25A38, PUS1, GLRX5, and ABCB7 mutations. SLC19A2 and mitochondrial DNA were only analyzed if characteristic syndromic features were apparent. Results. Twelve probands had biallelic mutations in SLC25A38. Seven ALAS2 mutations were detected in eight sporadic CSA cases, two being novel. We also identified a novel homozygous null PUSI mutation and novel mitochondrial DNA deletions in two patients with Pearson syndrome. No mutations were encountered in GLRX5, ABCB7, or SLC19A2. Conclusions. The remaining undefined probands (43%) can be grouped according to gender, family, and clinical characteristics, suggesting novel X-linked and autosomal recessive forms of CSA.

AB Beh double dagger et's disease is a chronic multisystemic inflammatory disorder characterized by orogenital ulcerations, uveitis, and occasional cardiac involvement. This report describes an atypical presentation of pediatric Beh double dagger et's disease with pulmonary emboli and a cardiac mass. A 16-year-old boy with a 2-year history of oral ulcers presented with weight loss, fever, joint pain, and a large tumor adhering to the free wall of the heart's right ventricle. Surgical biopsy demonstrated endomyocarditis with thrombus formation and led to the diagnosis. At the 2-year follow-up evaluation, intracardiac thrombus and pulmonic emboli had not recurred. Symptom control with immunosuppressive therapy was good.

AB OBJECTIVE: Moderately preterm infants (30-346/7 weeks' gestational age) represent the largest population of NICU residents. Whether their clinical outcomes are associated with differences in NICU nurse-staffing arrangements has not been assessed. The objective of this study was to test the influence of patient-to-nurse ratios (PNRs) on outcomes of care provided to moderately preterm infants.
PATIENTS AND METHODS: Using data from a prospective, multicenter, observational cohort study of 850 moderately preterm infants from 10 NICUs in California and Massachusetts, we tested for associations between PNR and several important clinical outcomes by using multivariate random-effects models. To correct for the influence of NICU size, we dichotomized the sample into those with an average daily census of <20 or >= 20 infants.
RESULTS: Overall, we found few clinically significant associations between PNR and clinical outcomes of care. Mean PNRs were higher in large compared with small NICUs (2.7 vs 2.1; P < .001). In bivariate analyses, an increase in PNR was associated with a slightly higher daily weight gain (5 g/day), greater gestational age at discharge, any intraventricular hemorrhage, and severe retinopathy of prematurity. After controlling for case mix, NICU size, and site of care, an additional patient per nurse was associated with a decrease in daily weight gain by 24%. Other variables were no longer independently associated with PNR.
CONCLUSIONS: In this population of moderately preterm infants, the PNR was associated with a decrease in daily weight gain, but was not associated with other measures of quality. In contrast with findings in the adult intensive care literature, measured clinical outcomes were similar across the range of nurse-staffing arrangements among participating NICUs. We conclude that the PNR is not useful for profiling hospitals' quality of care delivery to moderately preterm infants. Pediatrics 2010; 125: 320-326

AB OBJECTIVE: To evaluate the cost-effectiveness of newborn screening for medium-chain acyl-coenzyme A dehydrogenase deficiency (MCADD) incorporating quality-of-life effects for false-positive newborn screens and recommended dietary treatment.
METHODS: A computer simulation model was developed to predict costs and health outcomes for expanded newborn screening for MCADD compared with clinical identification. The modeled target population was a hypothetical cohort of 100 000 newborns in the United States. Probabilities, costs, and quality-of-life weights were derived from a long-term follow-up study of newborn screening compared with clinical identification, primary data collection, published data, and expert opinion. We used a lifetime time horizon and the societal perspective. The main outcome measure was the incremental cost-effectiveness ratio in dollars per quality-adjusted life-year (QALY) gained. Secondary outcomes included averted deaths and hospitalizations.
RESULTS: Using base-case assumptions, the cost-effectiveness of newborn screening for MCADD was $21 273 per QALY gained. The cost-effectiveness ratio increased to $21 278/QALY when the loss in quality of life associated with false-positive test results was incorporated and to $27 423/QALY when the quality of life associated with lifelong dietary recommendations for treating MCADD was incorporated. Results were sensitive to the false-positive rate for the newborn screening test and the cost of the initial screen.
CONCLUSIONS: Expanded newborn screening for MCADD is cost-effective compared with well-accepted pediatric health interventions. Losses in quality of life associated with dietary treatment for MCADD, however, may offset some of the gains in QALYs from newborn screening. Consideration of new disorders for expanded newborn screening panels should include the potential reduction in quality of life associated with treatments. Pediatrics 2010; 125:e286-e294

AB Recently, two proteins have been localized in the arcuate nucleus (ARC) and implicated in the regulation of food intake: the serine-threonine-kinase mammalian target of rapamycin (mTOR) as part of the TOR signaling complex 1 (TORC1), and nesfatin-1 derived from the precursor protein nucleobindin2. However, the exact cell types are not well described. Therefore, we performed double-labeling studies for NPY, CART, nesfatin-1 and pmTOR in the ARC. In this study, we showed that nesfatin-1 is not only intracellularly co-localized with cocaine- and amphetamine-regulated transcript (CART) peptide as reported before, but also with phospho-mTOR (pmTOR) and neuropeptide Y (NPY) in ARC neurons. Quantification revealed that 59 +/- 5% of the pmTOR-immunoreactive (it) neurons were immunoreactive for nesfatin-1. Moreover, double labeling for nesfatin-1 and NPY exhibited that 19 +/- 5% of the NPY positive cells were also immunoreactive for nesfatin-1. Furthermore, we could also confirm results from previous studies, showing that the majority of nesfatin-1 neurons are also positive for CART peptide, whereas most of the pmTOR is co-localized with NPY and only to a lesser extent with CART.

AB Little is known about CRF expression and regulation in the rat colon compared to the brain. We investigated CRF gene expression, cellular location, and regulation by endotoxin and corticosterone in the male rat colon at 6 h after intraperitoneal (ip) injection. CRF mRNA level, detected by reverse transcription-polymerase chain reaction (RT-PCR) was 1.3-fold higher in the distal than proximal colon and 3.4-fold higher in the proximal colonic submucosa plus muscle layers than in mucosa. CRF immunoreactivity was located in the epithelia, lamina propria and crypts, and co-localized with tryptophan hydroxylase. a marker for enterochromaffin (EC) cells, and in enteric neurons. Lipopolysaccharide (LPS, 100 mu g/kg, ip) increased defecation by 2.9-fold and upregulated CRF mRNA by 2.5-fold in the proximal and 1.1-fold in the distal colon while there was no change induced by corticosterone as monitored by quantitative PCR. LPS-induced increased CRF mRNA expression occurred in the submucosa plus muscle layers (1.5-fold) and the mucosa of proximal colon (0.9-fold). LIPS increased significantly CRF immunoreactivity in the submucosal and myenteric plexuses of proximal and distal colon compared to saline groups. These results indicate that in rats, CRF is expressed in both proximal and distal colon and more prominently in enteric neurons of the submucosa plus muscle layers and subject to upregulation at the gene and protein levels by LPS through corticosteroid independent pathways. These data suggests that colonic CRF may be part of the local effector limb of the CRF, receptor mediated colonic alterations induced by acute stress. (C) 2009 Elsevier Inc. All rights reserved.

AB Numerous peptides released from endocrine cells in the intestinal mucosa were established early on to be involved in the physiological regulation of food intake with a prominent role in termination of food ingestion when nutrients pass along the intestinal tract. Recently, peptides released from X/A-like endocrine cells of the gastric oxyntic mucosa were recognized as additional key players in the regulation of feeding and energy expenditure. Gastric X/A-like cells release the octanoylated peptide, ghrelin, the only known peripherally produced hormone stimulating food intake through interaction with growth hormone secretagogue I a receptor(GHS-R1a). Additionally, non-octanoylated (des-acyl) ghrelin present in the circulation at higher levels than ghrelin is currently discussed as potential modulator of food intake by opposing ghrelin's action independent from GHS-R1a although the functional significance remains to be established. Obestatin, a ghrelin-associated peptide was initially reported as anorexigenic modulator of ghrelin's orexigenic action. However, subsequent reports did not support this contention. Interesting is the recent identification of nesfatin-1, a peptide derived from the nucleobindin2 gene prominently expressed in gastric X/A-like cells in different vesicles than ghrelin. Circulating nesfatin-1 levels vary with metabolic state and peripheral or central injection inhibits dark phase feeding in rodents. Overall, these data point to an important role of gastric X/A-like cells in food intake regulation through the expression of the orexigenic peptide ghrelin along with des-acyl ghrelin and nesfatin-1 capable of reducing food intake upon exogenous injection although their mechanisms of action and functional significance remain to be established.

AB Normal personality and psychopathology have traditionally been conceptualized as separate or distinct areas of inquiry. However recent research exploring the hierarchical nature of personality traits suggests the possibility of integrating findings across these domains. This study used the Personality Assessment Inventory (Morey, 1991) and NEO-Personality Inventory-Revised (Costa & McCrae, 1992) to investigate the joint factor structure of normal personality and psychopathology. Factor analysis revealed a well defined three factor structure with scales from both instruments having prominent loadings on all the factors. The first joint PAI-NEO factor was marked by Neuroticism, Anxiety, Depression and Borderline Personality traits, the second factor had negative loadings for Agreeableness and Conscientiousness and positive loadings for Drug Abuse and Antisocial Personality traits. The third joint factor had positive loadings for Extraversion, Openness and Mania plus a secondary negative loading for Depression. The joint PAI-NEO factor structure bore a clear resemblance to the Big Three model of personality traits depicted in Markon, Krueger, and Watson's (2005) personality hierarchy. While preliminary the current findings suggest that normal personality and psychopathology may share a common latent structure and their shared structure may integrate into the broader hierarchy of personality traits.

AB Human disease is heterogeneous, with similar disease phenotypes resulting from distinct combinations of genetic and environmental factors. Small-molecule profiling can address disease heterogeneity by evaluating the underlying biologic state of individuals through non-invasive interrogation of plasma metabolite levels. We analyzed metabolite profiles from an oral glucose tolerance test (OGTT) in 50 individuals, 25 with normal (NGT) and 25 with impaired glucose tolerance (IGT). Our focus was to elucidate underlying biologic processes. Although we initially found little overlap between changed metabolites and preconceived definitions of metabolic pathways, the use of unbiased network approaches identified significant concerted changes. Specifically, we derived a metabolic network with edges drawn between reactant and product nodes in individual reactions and between all substrates of individual enzymes and transporters. We searched for "active modules''-regions of the metabolic network enriched for changes in metabolite levels. Active modules identified relationships among changed metabolites and highlighted the importance of specific solute carriers in metabolite profiles. Furthermore, hierarchical clustering and principal component analysis demonstrated that changed metabolites in OGTT naturally grouped according to the activities of the System A and L amino acid transporters, the osmolyte carrier SLC6A12, and the mitochondrial aspartate-glutamate transporter SLC25A13. Comparison between NGT and IGT groups supported blunted glucose- and/or insulin-stimulated activities in the IGT group. Using unbiased pathway models, we offer evidence supporting the important role of solute carriers in the physiologic response to glucose challenge and conclude that carrier activities are reflected in individual metabolite profiles of perturbation experiments. Given the involvement of transporters in human disease, metabolite profiling may contribute to improved disease classification via the interrogation of specific transporter activities.

TI CK1 epsilon Is Required for Breast Cancers Dependent on beta-Catenin
Activity

AB Background: Aberrant beta-catenin signaling plays a key role in several cancer types, notably colon, liver and breast cancer. However approaches to modulate beta-catenin activity for therapeutic purposes have proven elusive to date.
Methodology: To uncover genetic dependencies in breast cancer cells that harbor active beta-catenin signaling, we performed RNAi-based loss-of-function screens in breast cancer cell lines in which we had characterized beta-catenin activity. Here we identify CSNK1E, the gene encoding casein kinase 1 epsilon (CK1 epsilon) as required specifically for the proliferation of breast cancer cells with activated beta-catenin and confirm its role as a positive regulator of beta-catenin-driven transcription. Furthermore, we demonstrate that breast cancer cells that harbor activated beta-catenin activity exhibit enhanced sensitivity to pharmacological blockade of Wnt/beta-catenin signaling. We also find that expression of CK1e is able to promote oncogenic transformation of human cells in a beta-catenin-dependent manner.
Conclusions/Significance: These studies identify CK1 epsilon as a critical contributor to activated beta-catenin signaling in cancer and suggest it may provide a potential therapeutic target for cancers that harbor active beta-catenin. More generally, these observations delineate an approach that can be used to identify druggable synthetic lethal interactions with signaling pathways that are frequently activated in cancer but are difficult to target with the currently available small molecule inhibitors.

TI Antibiotic Prescribing for Acute Respiratory Infection and Subsequent
Outpatient and Hospital Utilization in Veterans With Spinal Cord Injury
and Disorder
SO PM&R
LA English
DT Article
AB Objective: To assess the association between antibiotic prescribing for acute respiratory infection (ARI) and subsequent health-care utilization in veterans with spinal cord injury and disorder (SCI/D).
Design: Retrospective cohort of veterans with SCI/D.
Setting: Veterans Affairs medical facilities that provide outpatient care.
Patients: Veterans with SCI/D with a diagnosis of acute bronchitis or upper respiratory infection during an outpatient visit between fiscal year 2006 and 2007 that did not result in same-clay hospitalization.
Independent Variable: Receipt of a new antibiotic prescription occurring within 3 clays before or after an ARI visit.
Main Outcome Measure: Subsequent outpatient visit or hospitalization within 30 days of the index ARI visit.
Results: A total of 1277 patients were identified with ARI; 53.2% were prescribed an antibiotic. An outpatient clinic visit within 30 days of the index ARI visit occurred in 47.0% of patients. Receipt of an antibiotic prescription was not associated with a subsequent outpatient visit. However, in those with certain chronic respiratory conditions (cough, shortness of breath, bronchitis not specified as acute or chronic, and allergic rhinitis), those prescribed antibiotics were less likely to return for an outpatient visit than those not prescribed antibiotics (adjusted relative risk = 0.77, 95% confidence interval = 0.61-0.97); no association was observed in those patients without these conditions. A total of 7.9% of patients were hospitalized within 30 days and did not differ by prescribing group. The 30-day mortality rate was 0.6%.
Conclusions: Certain chronic respiratory conditions in veterans with SCI/D may be risk factors for increased health-care utilization and potentially poor outcomes if a patient is not treated with antibiotics for ARI. However, in those without these conditions, those with ARI who were prescribed antibiotics have similar utilization to those not prescribed antibiotics. These data suggest that in the absence of chronic respiratory conditions, antibiotic use for ARI can be curbed in this population that is at high risk for respiratory complications.

AB Accumulating evidence finds a relative deficiency of peripheral membrane fatty acids in persons with affective disorders such as unipolar and bipolar depression. Here we sought to investigate whether postmortem brain fatty acids within the anterior cingulate cortex (BA-24) varied according to the presence of major depression at the time of death. Using capillary gas chromatography we measured fatty acids in a depressed group (n = 12), and in a control group without lifetime history of psychiatric diagnosis (n = 14). Compared to the control group, the depressed group showed significantly lower concentrations of numerous saturated and polyunsaturated fatty acids including both the n-3 and n-6 fatty acids. Additionally, significant correlations between age at death and precursor (or metabolites) in the n-3 fatty acid pathway were demonstrated in the depressed group but not in control subjects. In the n-6 fatty acid family, the ratio of 20:3(n-6)/18:2(n-6) was higher in patients than in control groups, whereas the ratio of 20A(n-6)/20:3(n-6) was relatively decreased in patients. Lastly, a significant negative correlation between age and the ratio of 20:4(n-6) to 22:6(n-3) was found in patients, but not in controls. Taken together, decreases in 22:6(n-3) may be caused, at least in part, by the diminished formation of 20:5(n-3), which is derived from 20:4(n-3) through a Delta 5 desaturase reaction. The present findings from postmortem brain tissue raise the possibility that an increased ratio of 20:4(n-6) to 22:6(n-3) may provide us with a biomarker for depression. Future research should further investigate these relationships. Published by Elsevier Ltd.

AB Objective: This study examined whether a collaborative care model for depression would improve clinical and functional outcomes for depressed patients with chronic general medical conditions in primary care practices in Puerto Rico. Methods: A total of 179 primary care patients with major depression and chronic general medical conditions were randomly assigned to receive collaborative care or usual care. The collaborative care intervention involved enhanced collaboration among physicians, mental health specialists, and care managers paired with depression-specific treatment guidelines, patient education, and follow-up. In usual care, study personnel informed the patient and provider of the diagnosis and encouraged patients to discuss treatment options with their provider. Depression severity was assessed with the Hopkins Symptom Checklist; social functioning was assessed with the 36-item Short Form. Results: Compared with usual care, collaborative care significantly reduced depressive symptoms and improved social functioning in the six months after randomization. Integration of collaborative care in primary care practices considerably increased depressed patients' use of mental health services. Conclusions: Collaborative care significantly improved clinical symptoms and functional status of depressed patients with coexisting chronic general medical conditions receiving treatment for depression in primary care practices in Puerto Rico. These findings highlight the promise of the collaborative care model for strengthening the relationship between mental health and primary care services in Puerto Rico.

AB Objective: Few studies have compared treatment outcomes of African-American, Hispanic, and non-Hispanic white patients with bipolar disorder. The U. S. Systematic Treatment Enhancement Program for Bipolar Disorder compared one-year outcomes for bipolar I or II disorder from each of these racial-ethnic groups. Methods: African Americans (N=155) were retrospectively compared with a matched group of non-Hispanic whites (N=729), and Hispanics (N=152) were compared with a separate matched group of non-Hispanic whites (N=822). Response and recovery outcomes were examined. Survival analysis was used to compare time to treatment response for depression (Montgomery-Asberg Depression Rating Scale) and mania (Young Mania Rating Scale) as well as global assessment of functioning (Global Assessment of Functioning). Results: For manic and depressive symptoms, time to response and proportion of responders were similar across groups. Over the study year the proportion of days well was similar across groups. A smaller proportion of African Americans met criteria for improved global functioning. Depression response among African Americans with psychotic symptoms was slower than the response among African Americans without psychotic symptoms and among non-Hispanic whites with or without psychotic symptoms. No differences between Hispanics and non-Hispanic whites in response times and recovery were observed. Conclusions: Results are consistent with U. S. clinical trials for other psychiatric disorders, which have reported similar outcomes for ratings of primary symptoms. Baseline psychotic symptoms are likely a significant contributor when African Americans with bipolar disorder are slow to recover. These results may be less generalizable to uninsured patients.

AB Background. Painful physical symptoms (PPS) are both common and reduce the likelihood of remission in major depressive disorder (MDD), based upon results of clinical trials in selected populations. Whether PI'S significantly contribute to poorer treatment outcome overall in primary or specialty psychiatric care settings remains Unclear.
Method. Out-patients (n = 2876) with MDD were treated in the first step of the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial with citalopram up to 60 mg/day for LIP to 14 weeks. Presence of painful symptoms, as well as severity of depression, physical illness, and demographic and treatment factors were examined. Time to and overall rates of remission were analysed in relation to the presence of PPS.
Results. Of the participants, 80% complained of PPS. These patients, both in primary and specialty psychiatric settings, had significantly, lower remission rates and took longer to remit. Increasing severity of PIS was associated with greater physical illness burden, lower socio-economic status, absence of private insurance and being female, African-American or Hispanic. After adjustment for these factors, patients with PPS no longer had significantly poorer treatment outcomes.
Conclusions. Presence and severity of PPS is an indicator of MDD that may have poorer treatment outcome with in initial selective serotonin reuptake inhibitor. These poorer treatment outcomes are multifactorial, however, and are not explained by the presence and severity of pain per se.

AB Background Unsafe medical care may cause substantial morbidity and mortality globally, despite imprecise estimates of the magnitude of the problem. To better understand the extent and nature of the problem of unsafe care, the WHO World Alliance for Patient Safety commissioned an overview of the world's literature on patient safety research.
Methods Major patient safety topics were identified through a consultative and investigative process and were categorised into the framework of structure, process and outcomes of unsafe care. Lead experts examined current evidence and identified major knowledge gaps relating to topics in developing, transitional and developed nations. The report was reviewed by internal and external experts and underwent improvements based on the feedback.
Findings Twenty-three major patient safety topics were examined. Much of the evidence of the outcomes of unsafe care is from developed nations, where prevalence studies demonstrate that between 3% and 16% of hospitalised patients suffer harm from medical care. Data from transitional and developing countries also suggest substantial harm from medical care. However, considerable gaps in knowledge about the structural and process factors that underlie unsafe care globally make solutions difficult to identify, especially in resource-poor settings.
Interpretation Harm from medical care appears to pose a substantial burden to the world's population. However, much of the evidence base comes from developed nations. Understanding the scope of and solutions for unsafe care for the rest of the world is a critical component of delivering safe, effective care to all of the world's citizens.

AB Purpose: To evaluate the diagnostic performance of coronary computed tomographic (CT) angiography for the diagnosis of mitral valve prolapse (MVP).
Materials and Methods: The retrospective case-controlled multicenter study protocol was approved by the institutional review boards. The U. S. part of the study was HIPAA compliant. One hundred twelve patients who underwent electrocardiographically gated 64-section coronary CT angiography (n = 60) or dual-source coronary CT angiography (n = 52) and transthoracic echocardiography (TTE) were included. Fifty-three patients with MVP were matched for age and sex with 59 patients without MVP. CT images were analyzed on three-, two-, and four-chamber (CH) views by two independent observers. MVP was defined as a greater than 2-mm displacement of leaflets below the annulus plane and was subclassified as "billowing" (bowing) or "flail leaflet" (free leaflet margin displacement). Leaflet thickness was measured and defined as thickened if it was greater than 2 mm.
Results: The diagnostic performance of CT when three- and two- CH views were combined for the diagnosis of MVP was as follows: sensitivity, 96%; specificity, 93%; positive predictive value (PPV), 93%; and negative predictive value, 96%. On four-CH views, the excursion of billowing was higher than it was on three- CH views (P<.001), and the PPV of the four-CH view for diagnosis of MVP was 89%. The correlation between CT and TTE for excursion of billowing was high (r = 0.80-0.91). In a subset of 32 patients, the agreement between CT and TTE for differentiation of billowing (n = 13) and flail leaflet (n = 2) was 100%. Leaflet thickening was more prevalent in patients with MVP than it was in those without (71% vs 20%, P<.001), and correlation with TTE was good (r = 0.81 [anterior leaflet] and 0.77 [posterior leaflet]).
Conclusion: The combined use of three- and two-CH views allows an accurate diagnosis of MVP at coronary CT angiography.

AB Purpose: First, to assess the feasibility of a protocol involving stress-induced perfusion evaluated at computed tomography (CT) combined with cardiac CT angiography in a single examination and second, to assess the incremental value of perfusion imaging over cardiac CT angio graphy in a dual-source technique for the detection of obstructive coronary artery disease ( CAD) in a high-risk population.
Materials and Methods: Institutional review board approval and informed patient consent were obtained before patient enrollment in the study. The study was HIPAA compliant. Thirty-five patients at high risk for CAD were prospectively enrolled for evaluation of the feasibility of CT perfusion imaging. All patients underwent retrospectively electrocardiographically gated ( helical) adenosine stress CT perfusion imaging followed by prospectively electrocardiographically gated ( axial) rest myocardial CT perfusion imaging. Analysis was performed in three steps: ( a) Coronary arterial stenoses were scored for severity and reader confidence at cardiac CT angiography, (b) myocardial perfusion defects were identified and scored for severity and reversibility at CT perfusion imaging, and ( c) coronary stenosis severity was reclassified according to perfusion findings at combined cardiac CT angiography and CT perfusion imaging. The sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of cardiac CT angiography before and after CT perfusion analysis were calculated.
Results: With use of a reference standard of greater than 50% stenosis at invasive angiography, all parameters of diagnostic accuracy increased after CT perfusion analysis: Sensitivity increased from 83% to 91%; specificity, from 71% to 91%; PPV, from 66% to 86%; and NPV, from 87% to 93%. The area under the receiver operating characteristic curve increased significantly, from 0.77 to 0.90 (P < .005).
Conclusion: A combination protocol involving adenosine perfusion CT imaging and cardiac CT angiography in a dual-source technique is feasible, and CT perfusion adds incremental value to cardiac CT angiography in the detection of significant CAD.

AB Purpose: To develop a relevant pathophysiologic model of human immunodeficiency virus (HIV)-associated dementia by studying regional variations in metabolite levels measured with magnetic resonance (MR) spectroscopic imaging and their relationship to immunologic measures and cognitive dysfunction.
Materials and Methods: This was a HIPAA-compliant, institutional review board-approved study involving written informed consent. Distributions of N-acetylaspartate (NAA), choline (Cho), and creatine (Cr) concentrations in 94 subjects (20 seronegative controls and 74 HIV-positive subjects; 34 of the HIV-positive subjects having HIV-associated dementia; 63 men, 31 women; mean age, 40 years) were determined with proton (hydrogen 1 [(1)H]) MR spectroscopic imaging. HIV-positive subjects underwent neuropsychological testing and blood and cerebrospinal fluid (CSF) analysis. Factor analysis was utilized to determine associations between metabolites across regions. Analysis of variance and t tests were used to isolate differences between cohorts.
Results: A "Cho factor" differentiated seronegative controls from HIV-infected cohorts, indicating elevated Cho levels across deep gray and white matter regions of HIV-positive individuals. An "NAA factor" differentiated those with dementia from those without and correlated best with psychomotor and executive function tests. A "Cr factor" indicated Cr elevations correlated with CSF monocyte chemoattractant protein-1 levels. NAA and Cr factor scores were strongly weighted to metabolite changes in white matter regions.
Conclusion: These results highlight the importance of white matter involvement in HIV-associated dementia and support the current pathogenesis model of glial cell proliferation in HIV infection, denoted by regional Cho elevations, and neuronal dysfunction and/or death, denoted by NAA decreases, associated with dementia. Factor analysis of MR spectroscopic imaging data is a useful method for determining regional metabolic variations in HIV infection and its neuropsychological correlates. (C) RSNA, 2010

AB Objective: To explore the relationship between employment status and community access, perceived community discrimination, social support from significant others, depressive symptoms, and gender-related variables for 83 men living with spinal cord injury. Study Design: Correlational research. Selling: Internet-based investigation employing spinal cord injury listservs. Main Outcome Measure: Participant employment status. Results: A forced-entry hierarchical logistic regression indicated that means of injury, community access and perceived community discrimination, social support from significant others, depressive symptoms, and men's adherence to masculine norms for primacy of work, self-reliance, and emotional control significantly predicted employment status. Conclusions: Psychosocial variables such as community access, perceived discrimination. social support from significant others. depressive symptoms, and gender identity represent important and understudied predictors of employment status among men living with spinal cord injury.

AB The ideal. cryopreservation protocol would combine the benefits of slow freezing with the benefits of vitrification. This report describes a method for the ultra-rapid vitrification of oocytes using slush nitrogen in quartz capillaries. The approach minimizes the thermal mass of the vitrification vessel by using open microcapillaries made of highly conductive quartz and achieves cooling rates of 250,000 degrees C/min. The process of vitrification can be optimized by maximizing the rate at which the sample is cooled, which allows for the use of tower cryoprotectant concentrations. Mouse oocytes can be successfully vitrified using 1.5 mol/l 1,2-propanediol and 0.5 mol/l trehalose and achieve survival rates of 90.0%(36/40). Fertilization and blastocyst formation rates of vitrified-warmed and fresh oocytes were not significantly different. A total of 120 blastocysts from each of the vitrified-warmed and fresh oocytes were transferred to surrogate mothers and 23 and 27 offspring were born respectively. All offspring in both groups were healthy, grew and bred normally and gave rise to a second generation of pups. Thus, an ultra-rapid vitrification technique has been developed for mouse oocytes that uses low concentrations of cryoprotectants and slush nitrogen in quartz capillaries, which combines the benefits of slow freezing and vitrification.

AB Uterine leiomyomas (also known as uterine fibroids) are the most common benign tumors of female reproductive tract and are the single most common indication for hysterectomies. Despite their high prevalence, the exact pathogenesis of these benign tumors is still unknown. One possible mechanism for leiomyoma formation. is dysregulation of mesenchymal stein cell activity. Mesenchymal stein cells have been identified in both human. and murine uteri and cancer stein cells have been identified in female reproductive malignancies. We compared stem/progenitor cell characteristics in both normal myometrium and the corresponding leiomyoma of patient's undergoing hysterectomies. We found that leiomyoma cells form fewer mesenchymal stein cell colonies and exhibit less Hoechst dye-excluding side population (SP) activity, which is a function associated with progenitor cells in other tissues, than cells isolated from normal myometrium. Whereas in normal myometrium, we observed heterogeneous expression of CD90, a cell surface marker associated the with differentiation potential of uterine fibroblasts, in leiomyomas, we observed homogenous expression of CD90, suggesting leiomyoma cells are more terminally differentiated. Furthermore, we found that while leiomyoma cells could only produce CD90 expressing cells, both CD90+ and CD90- myometrial cells could reestablish their original heterogeneous CD90 profile when expanded in vitro. These results suggest that normal myometrium contains cells with stem/progenitor cell activities that are absent in leiomyomas.

AB In the Past decade, the use of information technology (IT) to support healthcare delivery has greatly expanded. introducing new clinical information systems and updating existing systems require continued learning and training among registered nurses (RNs) and other clinicians. Consequently, a 5-item measure was designed as a subscale to the Practice Environment Scale of the Nursing Work Index. This new subscale, the Nursing Information Technology Subscale (NITS) measures RNs' Perception of the extent to which IT in their Practice environment supports Patient care delivery. A psychometric evaluation of the NITS was conducted at 8 Veterans Affairs hospitals. The findings demonstrated that this brief subscale has acceptable reliability as well as convergent and discriminant validity. (C) 2009 Wiley Periodicals, Inc. Res Nurs Health 33:48-59, 2010

AB In patients with acute respiratory distress syndrome (ARDS), inhaled vasodilator can result in important physiologic benefits (eg, improved hypoxemia, lower pulmonary arterial pressure, and improved right-ventricular function and cardiac output) without systemic hemodynamic effects. Inhaled nitric oxide (INO) and aerosolized prostacyclins are currently the most frequently used inhaled vasodilators. Inhaled prostacyclins are as effective physiologically as INO and cost less. Randomized controlled trials of INO in the treatment of ARDS have shown short-term physiologic benefits, but no benefit in long-term outcomes. No outcome studies have been reported on the use of prostacyclin in patients with ARDS. There is no role for the routine use of inhaled vasodilators in patients with ARDS. Inhaled vasodilator as a rescue therapy for severe refractory hypoxemia in patients with ARDS may be reasonable, but is controversial.

AB Introduction: The use of inhaled corticosteroids (ICS) in COPD may be associated with an increased risk of pneumonia. Little is known of this risk in newly diagnosed COPD patients. The objective of this study was to determine if the use of ICS among newly diagnosed COPD patients is associated with an increased risk of pneumonia hospitalizations.
Methods: Using data from the Department of Veterans Affairs and Centers for Medicare and Medicaid Services, a nested case-control study was performed. We identified patients 65 years of age or older with a new diagnosis of COPD from 1998 to 2002. A total of 145,586 patients were identified. Cases were defined based on hospitalization for pneumonia and exposure was prior use of ICS. Up to 10 controls were matched for each case based on age, sex, month and year of the case. The association between ICS use and pneumonia was evaluated with conditional logistic regression controlling for age, comorbidities, medication classes associated with the risk of pneumonia, and markers of COPD severity.
Results: There were 13,995 cases of pneumonia. The cohort was predominantly mate with an average age of 75.1 (SD = 5.4) years. The rate of pneumonia was 6.4 per 100 person-years. After adjustment for covariates, patients with current use of ICS were 1.38 (95% CI, 1.31-1.45) times more likely to have a hospitalization for pneumonia than those without current use of ICS.
Conclusions: The use of ICS among patients with newly diagnosed COPD is associated with an increased risk of hospitalization for pneumonia. Published by Elsevier Ltd.

AB Background: This study evaluated the effectiveness of first- and second-generation antipsychotics in reducing family burden associated with schizophrenia.
Methods: The family caregivers of 623 SCID-diagnosed patients enrolled in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) randomly assigned to a first-generation antipsychotic (perphenazine) or one of four second-generation drugs (olanzapine, quetiapine, risperidone or ziprasidone) were interviewed about resources provided and stresses experienced at baseline and followed for 18 months. Patient symptoms, side effects and service use were assessed as well. Hierarchical regression analyses evaluated the effect of treatment assignment on four burden factors: problem behavior, resource demands and disruption, impairment in activities of daily living and patient helpfulness. Intention-to-treat analyses with all available observations classified based on initial treatment assignment, including observations after medications changed were followed by secondary analyses excluding observations after the first medication change, i.e. only considering initial medication.
Results: Despite significant reductions on the problem behavior and resource demands/disruption factors, there were no significant differences between perphenazine and any of the second-generation medications. When only initial treatment period observations were included, patients were perceived as more helpful when medicated with perphenazine as compared to risperidone. in comparisons between second-generation drugs, patients on quetiapine were perceived as more helpful than those on risperidone (p = 0.004).
Conclusion: In this 18-month randomized trial. there was no evidence of superiority of second-generation antipsychotics in relieving family burden. (C) 2009 Published by Elsevier B.V.

Fibrosis at the edge of papillomas often entraps glands and creates the spurious impression of invasion. The proliferation of surface epithelial cells of papillomas does not give rise to unexpected diagnostic difficulties, but glandular proliferation within the stalks of papillomas often simulates the appearance of cribriform ductal carcinoma in situ. Needle biopsies of papillomas can deposit clusters of benign cells in a distribution that resembles an invasive carcinoma. Although papillomas overrun by ductal carcinoma in situ exhibit a papillary architecture, other features differentiate them from conventional papillary carcinomas. The presence of basal carcinoma cells with clear cytoplasm ("dimorphic" cells) and the formation of short stubby fronds sometimes cause pathologists to mistake papillary carcinomas for papillomas, and the bland cytologic characteristics of solid papillary carcinomas can lead to the same error. Conventional papillary carcinomas typically invade in a blunt manner. This phenomenon complicates the recognition of invasion by many papillary carcinomas and has given rise to controversy about the nature of the lesion classically known as "intracystic papillary carcinoma."

AB Hepatocellular carcinoma (HCC) is one of most lethal cancers worldwide. Strategic decisions for the advancement of molecular therapies in this neoplasm require a clear understanding of its molecular classification. Studies indicate aberrant activation of signaling pathways involved in cellular proliferation (e.g., epidermal growth factor and RAS/mitogen-activated protein kinase pathways), survival (e.g., Akt/mechanistic target of rapamycin pathway), differentiation (e.g., Wnt and Hedgehog pathways), and angiogenesis (e.g., vascular endothelial growth factor and platelet-derived growth factor), which is heterogeneously presented in each tumor. Integrative analysis of accumulated genomic datasets has revealed a global scheme of molecular classification of HCC tumors observed across diverse etiologic factors and geographic locations. Such a framework will allow systematic understanding of the frequently co-occurring molecular aberrations to design treatment strategy for each specific subclass of tumors. Accompanied by a growing number of clinical trials of molecular targeted drugs, diagnostic and prognostic biomarker development will be facilitated with special attention on study design and with new assay technologies specialized for archived fixed tissues. A new class of genomic information, microRNA dysregulation and epigenetic alterations, will provide insight for more precise understanding of disease mechanism and expand the opportunity of biomarker/therapeutic target discovery. These efforts will eventually enable personalized management of HCC.

DT Review
AB The Children's Oncology Group (COG) is a National Cancer Institute (NIH)-sponsored cooperative clinical trials group with the primary mission of conducting pediatric cancer clinical trials. COG has complex risk classification systems that are used to deliver risk-stratified therapy for many pediatric cancers, including clinical trials for acute lymphoblastic leukemia (ALL) and neuroblastoma (NB). Classification of patients is based on biological, clinical, and genomic data obtained at initial diagnosis and during the initial phases of therapy. The COG Web-based remote data entry (RDE) system enables submission of data in real time from central laboratories and treating institutions. The data are then used in an automated fashion to determine the risk group and corresponding treatment assignment for individual patients enrolled in COG clinical trials. Semin Oncol 37:53-59.

AB Objectives The primary objective was to determine the prevalence of sexually transmitted infections (STI) in a cohort of HIV-infected men who have sex with men (MSM) in their primary care setting, and to identify the demographic and behavioural characteristics of those infected with STI and the correlates of sexual transmission risk behaviour.
Methods At study entry, participants (n = 398) were tested for STI and their medical charts were reviewed for STI results in the previous year. Data on demographics, substance use, sexual behaviour and HIV disease characteristics were collected through a computer-assisted self-assessment and medical record extraction. Logistic regression analyses assessed characteristics of those with recent STI and recent transmission risk behaviour.
Results The sample was predominantly white (74.6%) and college educated (51.7%). On average, participants were 41.5 years old (SD 8.4) and had been HIV infected for 8.6 years (SD 6.7); 9% of the sample had an STI, with 6.4% testing positive for syphilis, 3.1% for gonorrhoea and 0.25% for chlamydia. Age and years since HIV diagnosis were significantly associated with testing positive for an STI, as was engaging in transmission risk behaviour and using methamphetamine, ketamine and inhalants. Substance use, particularly methamphetamine use, and being more recently diagnosed with HIV were each uniquely associated with transmission risk behaviour in a multivariable model.
Conclusions These results underscore the need to develop more effective secondary prevention interventions for HIV-infected MSM, tailored to more recently diagnosed patients, particularly those who are younger and substance users.

SO SOCIAL SCIENCE & MEDICINE
LA English

DE Risk; Incentives; Ethics; Participant payments; Human Participants

ID RESEARCH PARTICIPATION; UNDUE; ETHICS
AB In research involving human subjects, large participation payments often are deemed undesirable because they may provide 'undue inducement' for potential participants to expose themselves to risk. However, although large incentives may encourage participation, they also may signal the riskiness of a study's procedures. In three experiments, we measured people's interest in participating in potentially risky research studies, and their perception of the risk associated with those studies, as functions of participation payment amounts. All experiments took place 2007-2008 with an on-line nationwide sample or a sample from a northeastern U.S. city. We tested whether people judge studies that offer higher participation payments to be riskier, and, if so, whether this increased perception of risk increases time and effort spent learning about the risks. We found that high participation payments increased willingness to participate, but, consistent with the idea that people infer riskiness from payment amount, high payments also increased perceived risk and time spent viewing risk information. Moreover, when a link between payment amount and risk level was made explicit in Experiment 3, the relationship between high payments and perceived risk strengthened. Research guidelines usually prohibit studies from offering participation incentives that compensate for risks, yet these experiments' results indicate that potential participants naturally assume that the magnitude of risks and incentives are related. This discrepancy between research guidelines and participants' assumptions about those guidelines has implications for informed consent in human subjects research. (C) 2009 Elsevier Ltd.

AB Supportive social relationships, including a positive patient-practitioner relationship, have been associated with positive health outcomes. Using the data from a randomized controlled trial (RCT) undertaken in the Boston area of the United States, this study sought to identify baseline factors predictive of patients' response to an experimentally applied supportive patient-practitioner relationship. To sort through the hundreds of potential attributes affecting the patient-practitioner relationship, we applied a false discovery rate method borrowed from the field of genomics and bioinformatics. To our knowledge such a method has not previously been applied to generate hypotheses from clinical trial data. In a previous RCT, our team investigated the effect of the patient-practitioner relationship on symptom improvement in patients with irritable Bowel syndrome (IBS). Data were collected on a sample of 289 individuals with IBS using a three-week, single blind, three arm, randomized controlled design. We found that a supportive patient-practitioner relationship significantly improved symptomatology and quality of life. A complex, multi-level measurement package was used to prospectively measure change and identify factors associated with improvement. Using a local false discovery rate procedure, we examined the association of 452 baseline subject variables with sensitivity to treatment. Out of 452 variables, only two baseline factors, reclusiveness, and previous trial experience increased sensitivity to the supportive patient-practitioner relationship. A third variable, additional opportunity during the study for subjects to discuss their illness through experiential interview, was associated with improved outcomes among subjects who did not receive the supportive patient-practitioner relationship. The few variables associated with differential benefit suggest that a patient-centered supportive patient-practitioner relationship may be beneficial for most patients. This may be especially important for reclusive individuals. Within the context of our study, additional study attention in the form of repeated experiential interviews compensated for a lack of positive patient-practitioner support. A supportive patient-practitioner relationship may also help overcome low provider expectations for subjects with previous trial experience. These results converge with the results of the parent trial, implicating the importance of the social world in healing. (C) 2009 Elsevier Ltd. All rights reserved.

AB This study investigated the resilience resources and coping profiles of patients with diabetes. A total of 145 patients with diabetes completed a questionnaire packet including two measurements of coping (COPE and Coping Styles Questionnaires) and personal resources. Glycosylated haemoglobin (HbA(1c)) was also assessed. Resilience was defined by a factor score derived from measures of self-esteem, self-efficacy, self-mastery and optimism. All of the maladaptive coping subscales were negatively associated with resilience (r's range from -0.34 to -0.56, all p values are <0.001). Of the adaptive coping subscales, only acceptance, emotional support and pragmatism were positively associated with resilience. The upper, middle and lower tertiles of the resilience factor were identified, and the coping profiles of these groups differed significantly, with low-resilience patients favouring maladaptive strategies much more than those with high- or moderate-resilience resources do. Resilience groups did not differ in HbA(1c) levels; correlation coefficients of the coping subscales with HbA(1c) were explored. This study demonstrates a link between maladaptive coping and low resilience, suggesting that resilience impacts one's ability to manage the difficult treatment and lifestyle requirements of diabetes.

AB Background and Purpose-National guidelines recommend lipid testing for all patients with ischemic stroke and transient ischemic attack. This study examined the frequency and predictors for in-hospital low-density lipoprotein testing using data from a nationwide stroke registry.
Methods-Between 2003 and 2008, Get With The Guideline-Stroke (GWTG-Stroke) hospitals (n = 981) contributed 479 284 consecutive ischemic stroke or transient ischemic attack admissions. Logistic regression models were used to determine patient and hospital characteristics associated with lipid testing.
Results-Frequency of LDL measurement increased from 54.3% in 2003 to 81.9% in 2008 (P < 0.001), the adjusted OR for LDL measurement was 1.23 per additional calendar year (95% CI, 1.18 to 1.29; P < 0.001). The frequency of LDL measurement also increased with longer hospital program participation; the adjusted OR was 1.17 per additional year of GWTG-Stroke participation (95% CI, 1.12 to 1.23; P < 0.001). LDL measurement was lower in women, nonsmokers, those with atrial fibrillation, those with a history of stroke or transient ischemic attack, and in those with transient ischemic attack (versus ischemic stroke; all P < 0.001). LDL >= 100 mg/dL was seen in 52.1% of those tested, including in 35.5% of patients already prescribed lipid-lowering therapy before admission.
Conclusions-Rates of LDL measurement in hospitalized patients with ischemic stroke and transient ischemic attack have improved dramatically in this large quality improvement program, although disparities in testing still exist. Testing frequently revealed an LDL level that could prompt a change in clinical management. (Stroke. 2010; 41: 232-238.)

AB Background and Purpose-Evidence of atrial tachycardia/atrial fibrillation (AT/AF) is often sought in patients with ischemic stroke or transient ischemic attack. We studied patients with previous thromboembolic events (TE) who were implanted with devices capable of continuous arrhythmia monitoring to comprehensively quantify the incidence and duration of newly detected AT/AF.
Methods-This study represents a subgroup analysis of the TRENDS trial, which included patients with clinical indications for pacemakers or defibrillators and >= 1 stroke risk factors (heart failure, hypertension, age 65 or older, diabetes, or previous TE). A history of AF was not required. All implanted devices were capable of continuously monitoring the cumulative time spent in AT/AF each day. This analysis focuses primarily on the incidence and duration of newly detected AT/AF (defined as >= 5 minutes of AT/AF on any day) in patients with previous TE, no documented history of AF, and no warfarin or antiarrhythmic drug use.
Results-A total of 319 patients had a history of TE and >= 1 day of device data. Patients with a documented history of AF (n = 80), warfarin use (n = 56), or antiarrhythmic drug use (n = 20) were excluded from analysis. Of the remaining 163 patients, newly detected AT/AF was identified via the device in 45 patients (28%) over a mean follow-up of 1.1 +/- 0.7 years. AT/AF recurred infrequently, with only 12 patients experiencing AT/AF on >10% of follow-up days.
Conclusion-Newly detected episodes of AT/AF were found via continuous monitoring in 28% of patients with previous TE. Most episodes would not have been detected by standard intermittent monitoring techniques. (Stroke. 2010; 41: 256-260.)

AB Background and Purpose-We have previously reported the difference in length of stay and hospital charges for patients with cerebral aneurysms treated with either clipping or coiling at our institution. We now report an analysis of the same comparison at a national level conducted using the Nationwide Inpatient Sample database.
Methods-We obtained the Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project, Agency for Healthcare Quality and Research. The Nationwide Inpatient Sample is the largest all-payer inpatient care database in the US and represents approximate to 20% of all inpatient admissions to US nonfederal hospitals. Hospitalizations for clipping or coiling of ruptured and unruptured cerebral aneurysms from 2002 to 2006 were identified by cross-matching International Classification of Diseases-9 codes for diagnoses of subarachnoid hemorrhage (430) or unruptured cerebral aneurysm (437.3) with procedure codes for clipping (39.51) or coiling (39.79, 39.72, or 39.52) of cerebral aneurysms. Length of hospital stay and total hospital charges for clipping and coiling were compared using linear mixed models adjusted for the following patient and hospital-specific factors: gender, age, race/ethnicity, admission source and type, median income level in patient's postal code of residence, payer for care, comorbidities, and hospital cerebral aneurysm case volume, bed size, teaching status, rural/urban location, and geographic region.
Results-There were 9635 hospitalizations for ruptured aneurysm treatments (6019 clipping, 3616 coiling) and 9399 hospitalizations for unruptured aneurysm treatments (4700 clipping, 4699 coiling). For ruptured aneurysm patients, after adjusting for the effects of patient-specific and hospital-specific factors, clipping compared to coiling was associated with significantly longer length of stay (P < 0.0001) and significantly higher total hospital charges (P < 0.0001). For unruptured aneurysm patients, clipping compared to coiling was associated with significantly longer length of stay (P < 0.0001) and significantly higher total hospital charges (P < 0.0001). After adjusting for the effects of hospital-level and patient-level characteristics, clipping as compared to coiling was associated with an average of 1.2-times more days in hospitalization for ruptured patients and was associated with an average of 1.8-times more days in hospitalization for unruptured patients. On average, clipping resulted in $15 325 more in total charge for ruptured patients and resulted in $11 263 more in total charge for unruptured patients after considering all relevant hospital and patient characteristics.
Conclusions-The results of this nationwide analysis differed from the findings of our single institution study. Clipping compared to coiling was associated with significantly longer lengths of stay and significantly higher total hospital charges for both ruptured and unruptured aneurysm patients.

AB This position paper, written on behalf of the MASCC Psychosocial Study Group, reviews the most common psychosocial concerns and needs of cancer patients during all phases of the cancer continuum, from diagnosis to death or survivorship. Developments in psychosocial care at both individual and systems levels are surveyed and summarized, along with gaps in knowledge and research and needed improvements in the dissemination and application of acquired knowledge and expertise. The roles of culture, spirituality, and religion as part of psychosocial care are reviewed, along with families' and caregivers' specific psychosocial concerns and needs, and areas of needed psychosocial interventions in supportive cancer care. Deficits in recognizing and meeting patients' psychosocial needs at the system level are examined, and international guidelines and models of psychosocial care are reviewed, including their potential applications to local contexts. The paper calls for a shift to a new paradigm of care through adoption of an integrated approach to identify and meet the psychosocial needs of cancer patients and survivors as part of supportive care worldwide.

AB Despite the wide range of natural orifice transluminal endoscopic surgery (NOTES) procedures reported to date using a transgastric endoscopic approach, complications associated with gastrotomy creation have not been described. This study was conducted to identify the incidence and types of complications related to gastrotomy creation with the needle knife puncture and balloon dilatation technique for NOTES access to the peritoneal cavity.
Between May 2007 and August 2008, transgastric procedures were performed in 76 swine at a single institution. A total of 58 gastrotomies were created using the needle knife puncture and balloon dilatation technique without laparoscopic observation and 18 gastrotomies were created under laparoscopic visualization after CO(2) insufflation through a laparoscopic port. In all cases, a needle knife with an electrosurgical current of 25-W coagulation and/or 25-W cut and a wire-guided endoscopic balloon dilated to 20 mm were used to create the gastrotomy. All complications were collected prospectively and reviewed from laboratory medical records, operative reports, and necropsy findings.
NOTES gastrotomy-related complications occurred in 10/76 (13.2%) animals. Major complications occurred in six animals (7.9%), including four splenic lacerations, a mesenteric tear, and a fatal diaphragmatic injury. Minor complications occurred in four animals (5.3%), including three abdominal wall injuries and minor gastrotomy site bleeding. When pregastrotomy laparoscopic guidance was used, only one injury occurred in 18 animals (5.5%), but 9/58 (15.5%) gastrotomies performed without laparoscopic visualization caused some type of injury. The difference in rate of injury did not achieve statistical significance. No learning curve effect could be identified.
Injuries to adjacent viscera occur more often than is reported with the traditional transgastric needle knife NOTES access technique. Gastric punctures should be made either with laparoscopic visualization or by other techniques such as the PEG approach or with noncutting devices to reduce the incidence of visceral injury associated with transgastric peritoneal entry.

AB Adipose-derived stem cells (ASCs) may provide a clinical option for rebuilding damaged superficial lamina propria of the vocal fold. We investigated the effects of five hydrogels (hyaluronic acid [HA], collagen, fibrin, and cogels of fibrin-collagen and fibrin-HA) on the differentiation of ASCs, with the long-term goal of establishing the conditions necessary for controlling the differentiation of ASC into the functional equivalent of superficial lamina propria fibroblasts. Human ASCs were isolated and characterized by fluorescence-activated cell sorting and real-time polymerase chain reaction. According to fluorescence-activated cell sorting and gene analysis, over 90% of isolated ASCs expressed adult stem cell surface markers and expressed adult stem cell genes. Scaffold-specific gene expression and morphology were assessed by culturing the ASCs in three-dimensional hydrogels. Twofold higher amounts of total DNA were detected in fibrin and cogel cultures than in collagen and HA cultures. Elastin expression was significantly higher in cells grown in fibrin-based gels than in cells grown in other gels. Cells grown in the cogels showed elongated morphology, expressed decorin marker, and exhibited glycosaminoglycan synthesis, which indicate ASC differentiation. Our data suggest that it may be possible to control the differentiation of ASCs using scaffolds appropriate for vocal fold tissue engineering applications. In particular, cogels of HA or collagen with fibrin enhanced proliferation, differentiation, and elastin expression.

AB Prostanoids are bioactive lipids that interact with 7-membrane-spanning G-protein-coupled receptors on target cells to impart their biologic effects.(1) They include prostaglandins, prostacyclin, and thromboxane. Prostanoids are widely distributed; mediate several diverse biologic effects like platelet aggregation and smooth-muscle contraction; and are known to be involved in allergies, acquired immunity, and cancer metastasis.(2) Prostanoids have also been associated with breast and endometrial cancer promotion, and with the inhibition of melanoma. The role of prostanoids in the development of lung disease has been poorly understood. In particular, prostacyclin possesses significant anti-inflammatory and antimetastatic properties and is the main product of cyclooxygenase-2 activity in the lung. In fact, the balance of the various members of the prostanoids family, specifically the prosoglandins PGE(2) and prostacyclin (PGI(2)), seems to play an increasingly important role in the development of lung cancer. Gaining a better understanding of prostanoids and their associated pathways is critical to the future development of molecular-based and pharmaceutical treatments of lung disease.

AB GLP-1 (9-36)amide is the cleavage product of GLP-1 (7-36) amide, formed by the action of diaminopeptidyl peptidase-4 (Dpp4), and is the major circulating form in plasma. Whereas GLP-1(7-36)amide stimulates glucose-dependent insulin secretion, GLP-1(9-36)amide has only weak partial insulinotropic agonist activities on the GLP-1 receptor, but suppresses hepatic glucose production, exerts antioxidant cardioprotective actions and reduces oxidative stress in vasculature tissues. These insulin-like activities suggest a role for GLP-1 (936)amide in the modulation of mitochondrial functions by mechanisms independent of the GLP-1 receptor. In this paper, we discuss the current literature suggesting that GLP-1(9-36)amide is an active peptide with important insulin-like actions. These findings have implications in nutrient assimilation, energy homeostasis, obesity, and the use of Dpp4 inhibitors for the treatment of diabetes.

AB Uterine tumors resembling ovarian sex cord tumors (UTROSCT) are tumors of unclear histogenesis. The authors analyzed the ultrastructural features of 13 UTROSCT and correlated the findings with their immunohistochemical profile. Features included cells with frequent organoid, nested or cord-like arrangement (8), lumen formation (2; one of which showed surface microvilli), nuclei with irregular indentations (8), intermediate filaments (13), prominent paranuclear aggregates (5), cell junctions (9), desmosome-like junctions (2), tonofilaments (2), basal lamina (1), and cytoplasmic lipid droplets (7; prominent in 3). No dense bodies, subplasmalemmal densities or pinocytotic vesicles were seen. Ultrastructural epithelial differentiation was present in 2 tumors (positive for keratin or epithelial membrane antigen). Prominent lipid droplets correlated with sex cord markers positivity in 2 tumors. Ultrastructural features of smooth muscle differentiation were lacking and abundant paranuclear filaments did not correlate with myoid markers. UTROSCT are polyphenotypic neoplasms ultrastructurally with focal epithelial and variable sex cord-like differentiation. These findings suggest that UTROSCT may result from divergent differentiation in endometrial stromal tumors or represent a distinct group of uterine tumors with sex cord-like differentiation that are closer in histogenesis to ovarian sex cord stromal tumors. 60% diameter) was determined by peak systolic velocity (PSV) > 300 cm/s and renal aortic ratio (RAR) > 4.0. Renal function (creatinine) and blood pressure were measured at baseline and follow-up. SESs were implanted in 16 patients (22 renal arteries) during the study period. The study cohort was predominantly female (75%) with a mean age of 68 +/- 12 years. RA-ISR was treated with SESs with a mean diameter of 3.5 mm and mean length of 17.9 +/- 3.8 mm. The mean post-dilation balloon diameter was 4.8 +/- 0.6. The baseline renal artery PSV was 445 +/- 131 cm/s with a mean RAR of 5.0 +/- 1.6. Follow-up information was available in 21 renal arteries. During a median follow-up of 12 months (range: 9-15 months), 15 renal arteries (71.4%) developed recurrence of ISR by ultrasonographic criteria. Univariate analysis revealed that female sex was an independent predictor of recurrence of ISR after SES implantation (p < 0.05). In conclusion, placement of a SES for the treatment of ISR in renal arteries is associated with high initial technical success but significant restenosis on duplex ultrasonography at follow-up.

AB The authors have examined the effects of coaching sensory self-monitoring and reporting on pain-related variables in patients with lung cancer. Randomly assigned to coached or not-coached groups, 2 15 patients have their interactions with their providers audiotaped and complete study measures pre- and postintervention. Of the 151 patients who complete the 4-week study, those coached are more likely than those not coached to give their providers unsolicited sensory pain information and to mention it before their providers ask for it. The mean number of pain parameters discussed during the audiotaped clinic visit is statistically larger at study end for the coached group. Scores for analgesic adequacy, all pain indices except one, anxiety, depression, and catastrophizing coping are not significantly different. Although coaching increases the amount of pain data communicated to providers by patients with lung cancer, the magnitude is small and does not lead to improved adequacy of analgesics prescribed for each patient's pain level.

AB Accidental injury to the common bile duct is a rare but serious complication of laparoscopic cholecystectomy. Accurate visualization of the biliary ducts may prevent injury or allow its early detection. Conventional X-ray cholangiography is often used and can mitigate the severity of injury when correctly interpreted. However, it may be useful to have an imaging method that could provide real-time extrahepatic bile duct visualization without changing the field of view from the laparoscope. The purpose of the present study was to test a new near-infrared (NIR) fluorescent agent that is rapidly excreted via the biliary route in preclinical models to evaluate intraoperative real-time near infrared fluorescent cholangiography (NIRFC).
To investigate probe function and excretion, a lipophilic near-infrared fluorescent agent with hepatobiliary excretion was injected intravenously into one group of C57/BL6 control mice and four groups of C57/BL6 mice under the following experimentally induced conditions: (1) chronic biliary obstruction, (2) acute biliary obstruction (3) bile duct perforation, and (4) choledocholithiasis, respectively. The biliary system was imaged intravitally for 1 h with near-infrared fluorescence (NIRF) with an intraoperative small animal imaging system (excitation 649 nm, emission 675 nm).
The extrahepatic ducts and extraluminal bile were clearly visible due to the robust fluorescence of the excreted fluorochrome. Twenty-five minutes after intravenous injection, the target-to-background ratio peaked at 6.40 +/- A 0.83 but signal was clearly visible for similar to 60 min. The agent facilitated rapid identification of biliary obstruction and bile duct perforation. Implanted beads simulating choledocholithiasis were promptly identifiable within the common bile duct lumen.
Near-infrared fluorescent agents with hepatobiliary excretion may be used intraoperatively to visualize extrahepatic biliary anatomy and physiology. Used in conjunction with laparoscopic imaging technologies, the use of this technique should enhance hepatobiliary surgery.

AB The missing data problem is common in longitudinal or hierarchical structure studies. In this paper, we propose a correlated random-effects model to fit normal longitudinal or cluster data when the missingness mechanism is nonignorable. Computational challenges arise in the model fitting due to intractable numerical integrations. We obtain the estimates of the parameters based on an accurate approximation of the log likelihood, which has higher-order accuracy but with less computational burden than the existing approximation. We apply the proposed method to a real data set arising from an autism study. Copyright (C) 2009 John Wiley & Sons, Ltd.

AB Interleukin(IL)-2 and inflammation regulate effector and memory cytolytic T-lymphocyte (CTL) generation during infection. We demonstrate a complex interplay between IL-2 and inflammatory signals during CTL differentiation. IL-2 stimulation induced the transcription factor eomesodermin (Eomes), upregulated perforin (Prf1) transcription, and repressed re-expression of memory CTL markers Bcl6 and IL-7R alpha. Binding of Eomes and STAT5 to Prf1 cis-regulatory regions correlated with transcriptional initiation (increased recruitment of RNA polymerase II to the Prf1 promoter). Inflammation (CpG, IL-12) enhanced expression of IL-2R alpha and the transcription factor T-bet, but countered late Eomes and perforin induction while preventing IL-7R alpha repression by IL-2. After infection of mice with lymphocytic choriomeningitis virus, IL-2R alpha-deficient effector CD8(+) T cells expressed more Bcl6 but less perforin and granzyme B, formed fewer KLRG-1(+) and T-bet-expressing CTL, and killed poorly. Thus, inflammation influences both effector and memory CTL differentiation, whereas persistent IL-2 stimulation promotes effector at the expense of memory CTL development.

AB CD25, the high-affinity interleukin-2 (IL-2) receptor alpha chain, is rapidly upregulated by antigen-specific CD8(+) T cells after T cell receptor stimulation. Here, we demonstrate that during an acute viral infection, CD25 expression is quite dynamic-after initial upregulation, a subset of virus-specific T cells sustains CD25 expression longer than the rest. At this time when there is distinct heterogeneity in CD25 expression, examination of the in vivo fate of effector cells revealed that CD25(lo) cells, which are relatively less sensitive to IL-2, preferentially upregulate CD127 and CD62L and give rise to functional long-lived memory cells. In contrast, CD25(hi) cells perceiving prolonged IL-2 signals proliferate more rapidly, are prone to apoptosis, exhibit a more pronounced effector phenotype, and appear to be terminally differentiated. Consistent with this, sustained IL-2 receptor signaling during expansion drove terminal-effector differentiation. These data support the hypothesis that prolonged IL-2 signals during priming promote terminal-effector differentiation.

AB We tested the hypothesis that mild insults produce apoptotic, and severe insults necrotic, cells by subjecting adult Wistar rats to 60-min instead of 3-h generalized seizures. Rats' brains were evaluated 6 and 24 h later for evidence of neuronal necrosis by light and electron microscopy, the presence of TUNEL staining and active caspase-3 immunoreactivity, and for evidence of DNA laddering 24 h after seizures. Apoptotic neurons from the retrosplenial cortex of postnatal day 8 rat pups served as positive controls. Six and 24 h after seizures, 16 and 15 brain regions respectively out of 24 showed significant numbers of acidophilic neurons by hematoxylin and eosin stain. Three brain regions had significant numbers of TUNEL-positive neurons 24 h after seizures. No neurons showed active caspase-3 immunoreactivity. Acidophilic neurons were necrotic by electron-microscopic examination. Ultrastructurally, they were shrunken and electron-dense, with shrunken, pyknotic nuclei and swollen mitochondria with disrupted cristae. Nuclei did not contain the irregular chromatin clumps found after 3-h seizures. None of the six brain regions studied ultrastructurally that show DNA laddering 24 h after 3-h seizures showed DNA laddering 24 h after 60-min seizures, probably because there were too few damaged neurons, although the lack of chromatin clumping might have been a contributing factor. Following seizures, a mild as well as a severe insult produces caspase-3-negative necrotic neurons. These results do not support the hypothesis that mild insults produce apoptotic, and severe insults, necrotic, cells. Published by Elsevier Ireland Ltd.

TI Cytomegalovirus-Specific T Cells Persist at Very High Levels during

LOAD; IMMUNOSENESCENCE
AB Background: In healthy, HIV seronegative, CMV seropositive adults, a large proportion of T cells are CMV-specific. High-level CMV-specific T cell responses are associated with accelerated immunologic aging ("immunosenesence") in the elderly population. The impact of untreated and treated HIV infection on the frequency of these cells remains undefined.
Methodology/Principal Findings: We measured the proportion of CD4+ and CD8+ T cells responding to CMV pp65 and IE proteins was measured using flow cytometry in 685 unique HIV seronegative and seropositive individuals. The proportion of CMV-specific CD8+ T cells was consistently higher in the HIV-seropositive subjects compared to the HIV-seronegative subjects. This HIV effect was observed even in patients who lacked measurable immunodeficiency. Among the HIV-seropositive subjects, CMV-specific CD8+ T cell responses were proportionately lower during recent infection, higher during chronic untreated infection and higher still during long-term antiretroviral treated infection. The CD8+ T cell response to just two CMV proteins (pp65 and IE) was approximately 6% during long-term therapy, which was over twice that seen in HIV-seronegative persons. CMV-specific CD4+ T cell responses followed the same trends, but the magnitude of the effect was smaller.
Conclusions/Significance: Long-term successfully treated HIV infected patients have remarkably high levels of CMV-specific effector cells. These levels are similar to that observed in the elderly, but occur at much younger ages. Future studies should focus on defining the potential role of the CMV-specific inflammatory response in non-AIDS morbidity and mortality, including immunosenescence.

TI CBL Is Frequently Altered in Lung Cancers: Its Relationship to Mutations

AB Background: Non-small cell lung cancer (NSCLC) is a heterogeneous group of disorders with a number of genetic and proteomic alterations. c-CBL is an E3 ubiquitin ligase and adaptor molecule important in normal homeostasis and cancer. We determined the genetic variations of c-CBL, relationship to receptor tyrosine kinases (EGFR and MET), and functionality in NSCLC.
Methods and Findings: Using archival formalin-fixed paraffin embedded (FFPE) extracted genomic DNA, we show that c-CBL mutations occur in somatic fashion for lung cancers. c-CBL mutations were not mutually exclusive of MET or EGFR mutations; however they were independent of p53 and KRAS mutations. In normal/tumor pairwise analysis, there was significant loss of heterozygosity (LOH) for the c-CBL locus (22%, n = 8/37) and none of these samples revealed any mutation in the remaining copy of c-CBL. The c-CBL LOH also positively correlated with EGFR and MET mutations observed in the same samples. Using select c-CBL somatic mutations such as S80N/H94Y, Q249E and W802* (obtained from Caucasian, Taiwanese and African-American samples, respectively) transfected in NSCLC cell lines, there was increased cell viability and cell motility.
Conclusions: Taking the overall mutation rate of c-CBL to be a combination as somatic missense mutation and LOH, it is clear that c-CBL is highly mutated in lung cancers and may play an essential role in lung tumorigenesis and metastasis.

AB In addition to their pivotal role in thrombosis and wound repair, platelets participate in inflammatory responses. We investigated the role of platelets in the autoimmune disease rheumatoid arthritis. We identified platelet microparticles-submicrometer vesicles elaborated by activated platelets-in joint fluid from patients with rheumatoid arthritis and other forms of inflammatory arthritis, but not in joint fluid from patients with osteoarthritis. Platelet microparticles were proinflammatory, eliciting cytokine responses from synovial fibroblasts via interleukin-1. Consistent with these findings, depletion of platelets attenuated murine inflammatory arthritis. Using both pharmacologic and genetic approaches, we identified the collagen receptor glycoprotein VI as a key trigger for platelet microparticle generation in arthritis pathophysiology. Thus, these findings demonstrate a previously unappreciated role for platelets and their activation-induced microparticles in inflammatory joint diseases.

AB Correlated trial-to-trial variability in the activity of cortical neurons is thought to reflect the functional connectivity of the circuit. Many cortical areas are organized into functional columns, in which neurons are believed to be densely connected and to share common input. Numerous studies report a high degree of correlated variability between nearby cells. We developed chronically implanted multitetrode arrays offering unprecedented recording quality to reexamine this question in the primary visual cortex of awake macaques. We found that even nearby neurons with similar orientation tuning show virtually no correlated variability. Our findings suggest a refinement of current models of cortical microcircuit architecture and function: Either adjacent neurons share only a few percent of their inputs or, alternatively, their activity is actively decorrelated.

AB Acute exposure to ionizing radiation can cause lethal damage to the gastrointestinal (GI) tract, a condition called the GI syndrome. Whether the target cells affected by radiation to cause the GI syndrome are derived from the epithelium or endothelium and whether the target cells die by apoptosis or other mechanisms are controversial issues. Studying mouse models, we found that selective deletion of the proapoptotic genes Bak1 and Bax from the GI epithelium or from endothelial cells did not protect mice from developing the GI syndrome after sub-total-body gamma irradiation. In contrast, selective deletion of p53 from the GI epithelium, but not from endothelial cells, sensitized irradiated mice to the GI syndrome. Transgenic mice overexpressing p53 in all tissues were protected from the GI syndrome after irradiation. These results suggest that the GI syndrome is caused by the death of GI epithelial cells and that these epithelial cells die by a mechanism that is regulated by p53 but independent of apoptosis.

AB Our recent study demonstrated that a novel proteasome inhibitor NPI-0052 is distinct from bortezomib (Velcade) and, importantly, triggers apoptosis in multiple myeloma (MM) cells resistant to bortezomib. Here we demonstrate that combining NPI-0052 and lenalidomide (Revlimid) induces synergistic anti-MM activity in vitro using MM-cell lines or patient MM cells. NPI-0052 plus lenalidomide-induced apoptosis is associated with (1) activation of caspase-8, caspase-9, caspase-12, caspase-3, and poly(ADP) ribose polymerase; (2) activation of BH-3 protein BIM; (3) translocation of BIM to endoplasmic reticulum; (4) inhibition of migration of MM cells and angiogenesis; and (5) suppression of chymotrypsin-like, caspase-like, and trypsin-like proteasome activities. Importantly, blockade of BIM using siRNA significantly abrogates NPI-0052 plus lenalidomide-induced apoptosis. Furthermore, studies using biochemical inhibitors of caspase-8 versus caspase-9 demonstrate that NPI-0052 plus lenalidomide-triggered apoptosis is primarily dependent on caspase-8 signaling. In animal tumor model studies, low-dose combination of NPI-0052 and lenalidomide is well tolerated, significantly inhibits tumor growth, and prolongs survival. Taken together, our study provides the preclinical rationale for clinical protocols evaluating lenalidomide together with NPI-0052 to improve patient outcome in MM. (Blood. 2010;115:834-845)

AB Ageing in multicellular organisms typically involves a progressive decline in cell replacement and repair processes, resulting in several physiological deficiencies, including inefficient muscle repair, reduced bone mass, and dysregulation of blood formation (haematopoiesis). Although defects in tissue-resident stem cells clearly contribute to these phenotypes, it is unclear to what extent they reflect stem cell intrinsic alterations or age-related changes in the stem cell supportive microenvironment, or niche. Here, using complementary in vivo and in vitro heterochronic models, we show that age-associated changes in stem cell supportive niche cells deregulate normal haematopoiesis by causing haematopoietic stem cell dysfunction. Furthermore, we find that age-dependent defects in niche cells are systemically regulated and can be reversed by exposure to a young circulation or by neutralization of the conserved longevity regulator, insulin-like growth factor-1, in the marrow microenvironment. Together, these results show a new and critical role for local and systemic factors in signalling age-related haematopoietic decline, and highlight a new model in which blood-borne factors in aged animals act through local niche cells to induce age-dependent disruption of stem cell function.

AB In an effort to find new pharmacological modalities to overcome resistance to ATP-binding-site inhibitors of Bcr-Abl, we recently reported the discovery of GNF-2, a selective allosteric Bcr-Abl inhibitor. Here, using solution NMR, X-ray crystallography, mutagenesis and hydrogen exchange mass spectrometry, we show that GNF-2 binds to the myristate-binding site of Abl, leading to changes in the structural dynamics of the ATP-binding site. GNF-5, an analogue of GNF-2 with improved pharmacokinetic properties, when used in combination with the ATP-competitive inhibitors imatinib or nilotinib, suppressed the emergence of resistance mutations in vitro, displayed additive inhibitory activity in biochemical and cellular assays against T315I mutant human Bcr-Abl and displayed in vivo efficacy against this recalcitrant mutant in a murine bone-marrow transplantation model. These results show that therapeutically relevant inhibition of Bcr-Abl activity can be achieved with inhibitors that bind to the myristate-binding site and that combining allosteric and ATP-competitive inhibitors can overcome resistance to either agent alone.

AB As current radiological approaches cannot accurately localize prostate cancer in vivo, biopsies are conducted at random within prostates for patients at risk for prostate cancer, leading to high false-negative rates. Metabolomic imaging can map cancer-specific biomolecular profile values onto anatomical structures to direct biopsy. In this preliminary study, we evaluated five whole prostates removed during prostatectomy from biopsy-proven cancer patients on a 7-tesla human whole-body magnetic resonance scanner. Localized, multi-cross-sectional, multivoxel magnetic resonance spectra were used to construct a malignancy index based on prostate cancer metabolomic profiles obtained from previous intact tissue analyses with a 14-tesla spectrometer. This calculated malignancy index is linearly correlated with lesion size and demonstrates a 93 to 97% overall accuracy for detecting the presence of prostate cancer lesions, suggesting the potential clinical utility of this approach.

AB The appropriateness and timing of mitral valve surgery in patients with advanced heart failure and severe mitral regurgitation remains controversial. Recent surgical results provide evidence for beneficial effects on left ventricular remodeling and functional capacity. Given the absence of randomized trials comparing the outcomes of mitral valve surgery to medical therapy, however, clinical decision making regarding surgery for these fragile patients poses a dilemma to thoughtful clinicians.

AB Objectives This study sought to determine the association of high ankle brachial index (ABI) measurements with left ventricular (LV) mass, and to compare its strength with that of low ABI with LV mass.
Background Arterial stiffness leads to LV mass through nonatherosclerotic pathways in mice. In humans, a high ABI indicates stiff peripheral arteries and is associated with cardiovascular disease (CVD) events. Whether high ABI is associated with LV mass in humans and whether this might reflect consequences of arterial stiffness, atherosclerosis, or both is unknown.
Methods Among 4,972 MESA (Multi-Ethnic Study of Atherosclerosis) participants without clinical CVD, we used linear regression to evaluate the association of low (<0.90) and high (>1.40 or incompressible) ABI with LV mass by cardiac magnetic resonance imaging (MRI). Intermediate ABIs served as the reference category. To determine the effect of subclinical atherosclerosis, models were adjusted for common and internal carotid intima media thickness (cIMT) and natural log-transformed coronary artery calcification.
Results Compared with subjects with intermediate ABI, LV mass was higher with either low (2.70 g/m(2) higher, 95% confidence interval: 0.65 to 4.75) or high ABI (6.84 g/m2 higher, 95% confidence interval: 3.2 to 10.47) after adjustment for traditional CVD risk factors, kidney function, and C-reactive protein. However, further adjustment for cIMT and CAC substantially attenuated the association of low ABI with LV mass index (1.24 g/m(2) higher, 95% confidence interval: -0.84 to 3.33), whereas the association of high ABI was minimally altered (6.01 g/m(2) higher, 95% confidence interval: 2.36 to 9.67).
Conclusions High ABI is associated with greater LV mass; an association that is not attenuated with adjustment for subclinical atherosclerosis in nonperipheral arterial beds. High ABI might lead to greater LV mass through nonatherosclerotic pathways. (J Am Coll Cardiol 2010; 55: 342-9) (C) 2010 by the American College of Cardiology Foundation

TI The Behaviour of 5-Hydroxymethylcytosine in Bisulfite Sequencing

AB Background: We recently showed that enzymes of the TET family convert 5-mC to 5-hydroxymethylcytosine (5-hmC) in DNA. 5-hmC is present at high levels in embryonic stem cells and Purkinje neurons. The methylation status of cytosines is typically assessed by reaction with sodium bisulfite followed by PCR amplification. Reaction with sodium bisulfite promotes cytosine deamination, whereas 5-methylcytosine (5-mC) reacts poorly with bisulfite and is resistant to deamination. Since 5-hmC reacts with bisulfite to yield cytosine 5-methylenesulfonate (CMS), we asked how DNA containing 5-hmC behaves in bisulfite sequencing.
Methodology/Principal Findings: We used synthetic oligonucleotides with different distributions of cytosine as templates for generation of DNAs containing C, 5-mC and 5-hmC. The resulting DNAs were subjected in parallel to bisulfite treatment, followed by exposure to conditions promoting cytosine deamination. The extent of conversion of 5-hmC to CMS was estimated to be 99.7%. Sequencing of PCR products showed that neither 5-mC nor 5-hmC undergo C-to-T transitions after bisulfite treatment, confirming that these two modified cytosine species are indistinguishable by the bisulfite technique. DNA in which CMS constituted a large fraction of all bases (28/201) was much less efficiently amplified than DNA in which those bases were 5-mC or uracil (the latter produced by cytosine deamination). Using a series of primer extension experiments, we traced the inefficient amplification of CMS-containing DNA to stalling of Taq polymerase at sites of CMS modification, especially when two CMS bases were either adjacent to one another or separated by 1-2 nucleotides.
Conclusions: We have confirmed that the widely used bisulfite sequencing technique does not distinguish between 5-mC and 5-hmC. Moreover, we show that CMS, the product of bisulfite conversion of 5-hmC, tends to stall DNA polymerases during PCR, suggesting that densely hydroxymethylated regions of DNA may be underrepresented in quantitative methylation analyses.

AB The broadly neutralizing anti-HIV antibody 4E10 recognizes an epitope very close to the virus membrane on the glycoprotein gp41. It was previously shown that epitope recognition improves in a membrane context and that 4E10 binds directly, albeit weakly, to lipids. Furthermore, a crystal structure of Fab 4E10 complexed to an epitope peptide revealed that the centrally placed, protruding H3 loop of the antibody heavy chain does not form peptide contacts. To investigate the hypothesis that the H3 loop apex might interact with the viral membrane, two Trp residues in this region were substituted separately or in combination with either Ala or Asp by site-directed mutagenesis. The resultant IgG variants exhibited similar affinities for an epitope peptide as WT 4E10 but lower apparent affinities for both viral membrane mimetic liposomes and Env(-) virus. Variants also exhibited lower apparent affinities for Env(+) virions and failed to significantly neutralize a number of 4E10-sensitive viruses. For the extremely sensitive HXB2 virus, variants did neutralize, but at 37- to >250-fold lower titers than WT 4E10, with Asp substitutions exerting a greater effect on neutralization potency than Ala substitutions. Because reductions in lipid binding reflect trends in neutralization potency, we conclude that Trp residues in the antibody H3 loop enable membrane proximal epitope recognition through favorable lipid interactions. The requirement for lipophilic residues such as Trp adjacent to the antigen binding site may explain difficulties in eliciting 4E10-like neutralizing antibody responses by immunization and helps define a unique motif for antibody recognition of membrane proximal antigens.

AB Most genetically engineered mouse (GEM) models for colon cancer are based on tissuewide or germline gene modification, resulting in tumors predominantly of the small intestine. Several of these models involve modification of the adenomatous polyposis coli (Apc) gene and are excellent models for familial cancer predisposition syndromes. We have developed a stochastic somatic mutation model for sporadic colon cancer that presents with isolated primary tumors in the distal colon and recapitulates the entire adenoma-carcinoma-metastasis axis seen in human colon cancer. Using this model, we have analyzed tumors that are either solely mutant in the Apc gene or in combination with another colon cancer-associated mutant gene, the Kras G12D allele. Because of the restricted location in the distal colon, the natural history of the tumors can be analyzed by serial colonoscopy. As the mammalian target of rapamycin (mTOR) pathway is a critical component of the complex signaling network in colon cancer, we used this model to assess the efficacy of mTOR blockade through rapamycin treatment of mice with established tumors. After treatment, Apc mutant tumors were more than 80% smaller than control tumors. However, tumors that possessed both Apc and Kras mutations did not respond to rapamycin treatment. These studies suggest that mTOR inhibitors should be further explored as potential colorectal cancer therapies in patients whose tumors do not have activating mutations in KRAS.

AB Mutations in either the mitochondrial or nuclear genomes can give rise to respiratory chain disease (RCD), a large class of devastating metabolic disorders. Their clinical management is challenging, in part because we lack facile and accurate biomarkers to aid in diagnosis and in the monitoring of disease progression. Here we introduce a sequential strategy that combines biochemical analysis of spent media from cell culture with analysis of patient plasma to identify disease biomarkers. First, we applied global metabolic profiling to spotlight 32 metabolites whose uptake or secretion kinetics were altered by chemical inhibition of the respiratory chain in cultured muscle. These metabolites span a wide range of pathways and include lactate and alanine, which are used clinically as biomarkers of RCD. We next measured the cell culture-defined metabolites in human plasma to discover that creatine is reproducibly elevated in two independent cohorts of RCD patients, exceeding lactate and alanine in magnitude of elevation and statistical significance. In cell culture extracellular creatine was inversely related to the intracellular phosphocreatine: creatine ratio suggesting that the elevation of plasma creatine in RCD patients signals a low energetic state of tissues using the phosphocreatine shuttle. Our study identifies plasma creatine as a potential biomarker of human mitochondrial dysfunction that could be clinically useful. More generally, we illustrate how spent media from cellular models of disease may provide a window into the biochemical derangements in human plasma, an approach that could, in principle, be extended to a range of complex diseases.

AB The factors that enhance the waterborne spread of bacterial epidemics and sustain the pathogens in nature are unclear. The epidemic diarrheal disease cholera caused by Vibrio cholerae spreads through water contaminated with the pathogen. However, the bacteria exist in water mostly as clumps of cells, which resist cultivation by standard techniques but revive into fully virulent form in the intestinal milieu. These conditionally viable environmental cells (CVEC), alternatively called viable but nonculturable cells, presumably play a crucial role in cholera epidemiology. However, the precise mechanism causing the transition of V. cholerae to the CVEC form and this form's significance in the biology of the pathogen are unknown. Here we show that this process involves biofilm formation that is dependent on quorum sensing, a regulatory response that is controlled by cell density. V. cholerae strains carrying mutations in genes required for quorum sensing and biofilm formation displayed altered CVEC formation in environmental water following intestinal infections. Analysis of naturally occurring V. cholerae CVEC showed that organisms that adopt this quiescent physiological state typically exist as clumps of cells that comprise a single clone closely related to isolates causing the most recent local cholera epidemic. These results support a model of cholera transmission in which in vivo-formed biofilms convert to CVEC upon the introduction of cholera stools into environmental water. Our data further suggest that a temporary loss of quorum sensing due to dilution of extracellular autoinducers confers a selective advantage to communities of V. cholerae by blocking quorum-mediated regulatory responses that would break down biofilms and thus interfere with CVEC formation.

AB Background Variation in and irreversibility of platelet inhibition with clopiclogrel has led to controversy about its optimum dose and timing of administration in patients with acute coronary syndromes. We compared ticagrelor, a more potent reversible P2Y12 inhibitor with clopiclogrel in such patients.
Methods At randomisation, an invasive strategy was planned for 13408 (72.0%) of 18624 patients hospitalised for acute coronary syndromes (with or without ST elevation). in a double-blind, double-dummy study, patients were randomly assigned in a one-to-one ratio to ticagrelor and placebo (180 mg loading dose followed by 90 mg twice a day), or to clopidogrel and placebo (300-600 mg loading dose or continuation with maintenance dose followed by 75 mg per day) for 6-12 months. All patients were given aspirin. The primary composite endpoint was cardiovascular death, myocardial infarction, or stroke. Analyses were by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00391872.
Findings 6732 patients were assigned to ticagrelor and 6676 to clopidogrel. The primary composite endpoint occurred in fewer patients in the ticagrelor group than in the clopiclogrel group (569 [event rate at 360 days 9.0%] vs 668 [10.7%], hazard ratio 0.84, 95% CI 0.75-0.94; p=0.0025). There was no difference between clopiclogrel and ticagrelor groups in the rates of total major bleeding (691 [11.6%] vs 689 [11.5%], 0.99 [0.89-1.10]; p=0.8803) or severe bleeding, as defined according to the Global Use of Strategies To Open occluded coronary arteries, (198 [3.2%] vs 185 [2.9%], 0.91 [0.74-1.12]; p=0.3785).
Interpretation Ticagrelor seems to be a better option than clopidogrel for patients with acute coronary syndromes for whom an early invasive strategy is planned.

HIF-1; ACETYLATION
AB SIRT6 is a member of a highly conserved family of NAD(+)-dependent deacetylases with various roles in metabolism, stress resistance, and life span. SIRT6-deficient mice develop normally but succumb to a lethal hypoglycemia early in life; however, the mechanism underlying this hypoglycemia remained unclear. Here, we demonstrate that SIRT6 functions as a histone H3K9 deacetylase to control the expression of multiple glycolytic genes. Specifically, SIRT6 appears to function as a corepressor of the transcription factor Hif1 alpha, a critical regulator of nutrient stress responses. Consistent with this notion, SIRT6-deficient cells exhibit increased Hif1 alpha activity and show increased glucose uptake with upregulation of glycolysis and diminished mitochondrial respiration. Our studies uncover a role for the chromatin factor SIRT6 as a master regulator of glucose homeostasis and may provide the basis for novel therapeutic approaches against metabolic diseases, such as diabetes and obesity.

AB Recently, the P86L alteration in CALHM1 (calcium homeostasis modulator-1) was reported to be associated with Alzheimer's disease (AD). Moreover, the risk allele increased amyloid-beta (A beta) levels in conditioned media from cultured cells. Therefore, we hypothesized that CALHM1 P86L may modulate A beta or tau levels in cerebrospinal fluid (CSF). Nearly 200 individuals with AD or other cognitive disorders were included for CSF analysis and CALHM1 genotyping. No significant differences in CSF levels of A beta 42, tau or phospho-tau were found across the various CALHM1 genotypes. In conclusion, we found no evidence that CALHM1 P86L is associated with altered CSF levels of the investigated AD biomarkers. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

AB We have previously shown clinical activity of a mammalian target of rapamycin (mTOR) complex 1 inhibitor in Waldenstrom macroglobulinemia (WM). However, 50% of patients did not respond to therapy. We therefore examined mechanisms of activation of the phosphoinositide 3-kinase (PI3K)/Akt/mTOR in WM, and mechanisms of overcoming resistance to therapy. We first demonstrated that primary WM cells show constitutive activation of the PI3K/Akt pathway, supported by decreased expression of phosphate and tensin homolog tumor suppressor gene (PTEN) at the gene and protein levels, together with constitutive activation of Akt and mTOR. We illustrated that dual targeting of the PI3K/mTOR pathway by the novel inhibitor NVP-BEZ235 showed higher cytotoxicity on WM cells compared with inhibition of the PI3K or mTOR pathways alone. In addition, NVP-BEZ235 inhibited both rictor and raptor, thus abrogating the rictor-induced Akt phosphorylation. NVP-BEZ235 also induced significant cytotoxicity in WM cells in a caspase-dependent and -independent manner, through targeting the Forkhead box transcription factors. In addition, NVP-BEZ235 targeted WM cells in the context of bone marrow microenvironment, leading to significant inhibition of migration, adhesion in vitro, and homing in vivo. These studies therefore show that dual targeting of the PI3K/mTOR pathway is a better modality of targeted therapy for tumors that harbor activation of the PI3K/mTOR signaling cascade, such as WM.

AB Cyclin D1 belongs to the core cell cycle machinery, and it is frequently overexpressed in human cancers(1,2). The full repertoire of cyclin D1 functions in normal development and oncogenesis is unclear at present. Here we developed Flag-and haemagglutinin-tagged cyclin D1 knock-in mouse strains that allowed a high-throughput mass spectrometry approach to search for cyclin D1-binding proteins in different mouse organs. In addition to cell cycle partners, we observed several proteins involved in transcription. Genome-wide location analyses (chromatin immunoprecipitation coupled to DNA microarray; ChIP-chip) showed that during mouse development cyclin D1 occupies promoters of abundantly expressed genes. In particular, we found that in developing mouse retinas-an organ that critically requires cyclin D1 function(3,4)-cyclin D1 binds the upstream regulatory region of the Notch1 gene, where it serves to recruit CREB binding protein (CBP) histone acetyltransferase. Genetic ablation of cyclin D1 resulted in decreased CBP recruitment, decreased histone acetylation of the Notch1 promoter region, and led to decreased levels of the Notch1 transcript and protein in cyclin D1-null (Ccnd1(-/-)) retinas. Transduction of an activated allele of Notch1 into Ccnd1(-/-) retinas increased proliferation of retinal progenitor cells, indicating that upregulation of Notch1 signalling alleviates the phenotype of cyclin D1-deficiency. These studies show that in addition to its well-established cell cycle roles, cyclin D1 has an in vivo transcriptional function in mouse development. Our approach, which we term 'genetic-proteomic', can be used to study the in vivo function of essentially any protein.

AB BACKGROUND
Establishing the genetic basis of phenotypes such as skeletal dysplasia in model organisms can provide insights into biologic processes and their role in human disease.
METHODS
We screened mutagenized mice and observed a neonatal lethal skeletal dysplasia with an autosomal recessive pattern of inheritance. Through genetic mapping and positional cloning, we identified the causative mutation.
RESULTS
Affected mice had a nonsense mutation in the thyroid hormone receptor interactor 11 gene (Trip11), which encodes the Golgi microtubule-associated protein 210 (GMAP-210); the affected mice lacked this protein. Golgi architecture was disturbed in multiple tissues, including cartilage. Skeletal development was severely impaired, with chondrocytes showing swelling and stress in the endoplasmic reticulum, abnormal cellular differentiation, and increased cell death. Golgi-mediated glycosylation events were altered in fibroblasts and chondrocytes lacking GMAP-210, and these chondrocytes had intracellular accumulation of perlecan, an extracellular matrix protein, but not of type II collagen or aggrecan, two other extracellular matrix proteins. The similarities between the skeletal and cellular phenotypes in these mice and those in patients with achondrogenesis type 1A, a neonatal lethal form of skeletal dysplasia in humans, suggested that achondrogenesis type 1A may be caused by GMAP-210 deficiency. Sequence analysis revealed loss-of-function mutations in the 10 unrelated patients with achondrogenesis type 1A whom we studied.
CONCLUSIONS
GMAP-210 is required for the efficient glycosylation and cellular transport of multiple proteins. The identification of a mutation affecting GMAP-210 in mice, and then in humans, as the cause of a lethal skeletal dysplasia underscores the value of screening for abnormal phenotypes in model organisms and identifying the causative mutations.

AB We present an application of a previously developed agent-based glioma model (Chen et al 2009 Biosystems 95 234-42) for predicting spatio-temporal tumor progression using a patient-specific MRI lattice derived from apparent diffusion coefficient (ADC) data. Agents representing collections of migrating glioma cells are initialized based upon voxels at the outer border of the tumor identified on T1-weighted (Gd+) MRI at an initial time point. These simulated migratory cells exhibit a specific biologically inspired spatial search paradigm, representing a weighting of the differential contribution from haptotactic permission and biomechanical resistance on the migration decision process. ADC data from 9 months after the initial tumor resection were used to select the best search paradigm for the simulation, which was initiated using data from 6 months after the initial operation. Using this search paradigm, 100 simulations were performed to derive a probabilistic map of tumor invasion locations. The simulation was able to successfully predict a recurrence in the dorsal/posterior aspect long before it was depicted on T1-weighted MRI, 18 months after the initial operation.

AB In radiation therapy, intensity maps involving margins have long been used to counteract the effects of dose blurring arising from motion. More recently, intensity maps with increased intensity near the edge of the tumour (edge enhancements) have been studied to evaluate their ability to offset similar effects that affect tumour coverage. In this paper, we present a mathematical methodology to derive margin and edge-enhanced intensity maps that aim to provide tumour coverage while delivering minimum total dose. We show that if the tumour is at most about twice as large as the standard deviation of the blurring distribution, the optimal intensity map is a pure scaling increase of the static intensity map without any margins or edge enhancements. Otherwise, if the tumour size is roughly twice (or more) the standard deviation of motion, then margins and edge enhancements are preferred, and we present formulae to calculate the exact dimensions of these intensity maps. Furthermore, we extend our analysis to include scenarios where the parameters of the motion distribution are not known with certainty, but rather can take any value in some range. In these cases, we derive a similar threshold to determine the structure of an optimal margin intensity map.

AB Background: The hedgehog (Hh) pathway has been implicated in the pathogenesis of cancer including pancreatic ductal adenocarcinoma (PDAC). Recent studies have suggested that the oncogenic function of Hh in PDAC involves signaling in the stromal cells rather than cell autonomous effects on the tumor cells. However, the origin and nature of the stromal cell type(s) that are responsive to Hh signaling remained unknown. Since Hh signaling plays a crucial role during embryonic and postnatal vasculogenesis, we speculated that Hh ligand may act on tumor vasculature specifically focusing on bone marrow (BM)-derived cells.
Methodology/Principal Findings: Cyclopamine was utilized to inhibit the Hh pathway in human PDAC cell lines and their xenografts. BM transplants, co-culture systems of tumor cells and BM-derived pro-angiogenic cells (BMPCs) were employed to assess the role of tumor-derived Hh in regulating the BM compartment and the contribution of BM-derived cells to angiogenesis in PDAC. Cyclopamine administration attenuated Hh signaling in the stroma rather than in the cancer cells as reflected by decreased expression of full length Gli2 protein and Gli1 mRNA specifically in the compartment. Cyclopamine inhibited the growth of PDAC xenografts in association with regression of the tumor vasculature and reduced homing of BM-derived cells to the tumor. Host-derived Ang-1 and IGF-1 mRNA levels were downregulated by cyclopamine in the tumor xenografts. In vitro co-culture and matrigel plug assays demonstrated that PDAC cell-derived Shh induced Ang-1 and IGF-1 production in BMPCs, resulting in their enhanced migration and capillary morphogenesis activity.
Conclusions/Significance: We identified the BMPCs as alternative stromal targets of Hh-ligand in PDAC suggesting that the tumor vasculature is an attractive therapeutic target of Hh blockade. Our data is consistent with the emerging concept that BM-derived cells make important contributions to epithelial tumorigenesis.

AB Purpose
To evaluate geriatric assessment (GA) domains in relation to clinically important outcomes in older breast cancer survivors.
Methods
Six hundred sixty women diagnosed with primary breast cancer in four US geographic regions (Los Angeles, CA; Minnesota; North Carolina; and Rhode Island) were selected with disease stage I to IIIA, age >= 65 years at date of diagnosis, and permission from attending physician to contact. Data were collected over 7 years of follow-up from consenting patients' medical records, telephone interviews, physician questionnaires, and the National Death Index. Outcomes included self-reported treatment tolerance and all-cause mortality. Four GA domains were described by six individual measures, as follows: sociodemographic by adequate finances; clinical by Charlson comorbidity index (CCI) and body mass index; function by number of physical function limitations; and psychosocial by the five-item Mental Health Index (MHI5) and Medical Outcomes Study Social Support Survey (MOS-SSS). Associations were evaluated using t tests, chi(2) tests, and regression analyses.
Results
In multivariable regression including age and stage, three measures from two domains (clinical and psychosocial) were associated with poor treatment tolerance; these were CCI >= 1 (odds ratio [OR] = 2.49; 95% CI, 1.18 to 5.25), MHI5 score less than 80 (OR = 2.36; 95% CI, 1.15 to 4.86), and MOS-SSS score less than 80 (OR = 3.32; 95% CI, 1.44 to 7.66). Four measures representing all four GA domains predicted mortality; these were inadequate finances (hazard ratio [HR] = 1.89; 95% CI, 1.24 to 2.88; CCI >= 1 (HR = 1.38; 95% CI, 1.01 to 1.88), functional limitation (HR = 1.40; 95% CI, 1.01 to 1.93), and MHI5 score less than 80 (HR = 1.34; 95% CI, 1.01 to 1.85). In addition, the proportion of women with these outcomes incrementally increased as the number of GA deficits increased.
Conclusion
This study provides longitudinal evidence that GA domains are associated with poor treatment tolerance and predict mortality at 7 years of follow-up, independent of age and stage of disease.

TI Provision of Spiritual Care to Patients With Advanced Cancer:
Associations With Medical Care and Quality of Life Near Death
SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID TREATMENT PREFERENCES; TERMINALLY-ILL; ETHNIC-DIFFERENCES; PALLIATIVE
CARE; BREAST-CANCER; END; NEEDS; HOPE; ACKNOWLEDGMENT; ACCEPTABILITY
AB Purpose
To determine whether spiritual care from the medical team impacts medical care received and quality of life (QoL) at the end of life (EoL) and to examine these relationships according to patient religious coping.
Patients and Methods
Prospective, multisite study of patients with advanced cancer from September 2002 through August 2008. We interviewed 343 patients at baseline and observed them (median, 116 days) until death. Spiritual care was defined by patient-rated support of spiritual needs by the medical team and receipt of pastoral care services. The Brief Religious Coping Scale (RCOPE) assessed positive religious coping. EoL outcomes included patient QoL and receipt of hospice and any aggressive care (eg, resuscitation). Analyses were adjusted for potential confounders and repeated according to median-split religious coping.
Results
Patients whose spiritual needs were largely or completely supported by the medical team received more hospice care in comparison with those not supported (adjusted odds ratio [AOR] = 3.53; 95% CI, 1.53 to 8.12, P = .003). High religious coping patients whose spiritual needs were largely or completely supported were more likely to receive hospice (AOR = 4.93; 95% CI, 1.64 to 14.80; P = .004) and less likely to receive aggressive care (AOR = 0.18; 95% CI, 0.04 to 0.79; P = .02) in comparison with those not supported. Spiritual support from the medical team and pastoral care visits were associated with higher QOL scores near death (20.0 [95% CI, 18.9 to 21.1] v 17.3 [95% CI, 15.9 to 18.8], P = .007; and 20.4 [95% CI, 19.2 to 21.1] v 17.7 [95% CI, 16.5 to 18.9], P = .003, respectively).
Conclusion
Support of terminally ill patients' spiritual needs by the medical team is associated with greater hospice utilization and, among high religious copers, less aggressive care at EoL. Spiritual care is associated with better patient QoL near death.

TI Pathology Review of Thin Melanoma and Melanoma in Situ in a
Multidisciplinary Melanoma Clinic: Impact on Treatment Decisions

OPINION; LYMPH-NODE POSITIVITY; MALIGNANT-MELANOMA; STAGING SYSTEM;
MITOTIC RATE; INTEROBSERVER VARIABILITY; BRESLOW DEPTH; CLARK LEVEL
AB Purpose
Patients with thin melanoma (<= 1.0 mm) and melanoma in situ (MIS) represent the majority of newly diagnosed melanoma. We estimated the impact of expert review of outside pathology material on the staging and thus treatment decisions affecting patients referred to a multidisciplinary clinic with early-stage melanoma.
Patients and Methods
We studied patients with a diagnosis of thin melanoma or MIS referred to H. Lee Moffitt Cancer Center from 2006 to 2009. After comparing the referring laboratory and in-house dermatopathologic interpretations, we calculated any differences in diagnosis and tumor staging and the potential impact of differences in diagnosis and staging on prognosis and surgical treatment using the National Comprehensive Cancer Network clinical guidelines.
Results
The overall pathologic discordance rate in diagnosis was 4% (15 of 420 patients; 95% CI, 2% to 6%). The overall change in tumor staging rate was 24% (97 of 405 patients; 95% CI, 20% to 28%). Pathology review led to changes in surgical excision margins in 12% of patients (52 of 420 patients; 95% CI, 9% to 16%) and in the decision about whether to perform a sentinel lymph node biopsy in 16% of patients (67 of 420 patients; 95% CI, 13% to 20%). Key pathologic factors, particularly mitotic rate, were frequently missing from outside pathology reports.
Conclusion
Our data suggest that review of thin melanoma or MIS by an expert dermatopathologist results in frequent, clinically meaningful alterations in diagnosis, staging, prognosis, and surgical treatment. Referral of these patients to a multidisciplinary melanoma clinic is appropriate, and management of such patients should include review of the biopsy whenever feasible.

AB Purpose
To review the evidence about the efficacy and utility of radiofrequency ablation (RFA) for hepatic metastases from colorectal cancer (CRHM).
Methods
The American Society of Clinical Oncology (ASCO) convened a panel to conduct and analyze a comprehensive systematic review of the RFA literature from Medline and the Cochrane Collaboration Library.
Results
Because data were considered insufficient to form the basis of a practice guideline, ASCO has instead published a clinical evidence review. The evidence is from single-arm, retrospective, and prospective trials. No randomized controlled trials have been included. The following three clinical issues were considered by the panel: the efficacy of surgical hepatic resection versus RFA for resectable tumors; the utility of RFA for unresectable tumors; and RFA approaches (open, laparoscopic, or percutaneous). Evidence suggests that hepatic resection improves overall survival (OS), particularly for patients with resectable tumors without extrahepatic disease. Careful patient and tumor selection is discussed at length in the literature. RFA investigators report a wide variability in the 5-year survival rate (14% to 55%) and local tumor recurrence rate (3.6% to 60%). The reported mortality rate was low (0% to 2%), and the major complications rate was commonly reported to be between 6% and 9%. RFA is currently performed with all three approaches.
Conclusion
There is a compelling need for more research to determine the efficacy and utility of RFA to increase local recurrence-free, progression-free, and disease-free survival as well as OS for patients with CRHM. Clinical trials have established that hepatic resection can improve OS for patients with resectable CRHM.

AB We present a new class of polymeric ligands for quantum dot (OD) water solubilization to yield biocompatible and derivatizable QDs with compact size (similar to 10-12 nm diameter), high quantum yields (>50%), excellent stability across a large pH range (pH 5-10.5), and low nonspecific binding. To address the fundamental problem of thiol instability in traditional ligand exchange systems, the polymers here employ a stable multidentate imidazole binding motif to the OD surface. The polymers are synthesized via reversible addition-fragmentation chain transfer-mediated polymerization to produce molecular weight controlled monodisperse random copolymers from three types of monomers that feature imidazole groups for CID binding, polyethylene glycol (PEG) groups for water solubilization, and either primary amines or biotin groups for derivatization. The polymer architecture can be tuned by the monomer ratios to yield aqueous QDs with targeted surface functionalities. By incorporating amino-PEG monomers, we demonstrate covalent conjugation of a dye to form a highly efficient QD-dye energy transfer pair as well as covalent conjugation to streptavidin for high-affinity single molecule imaging of biotinylated receptors on live cells with minimal nonspecific binding. The small size and low serum binding of these polymer-coated QDs also allow us to demonstrate their utility for in vivo imaging of the tumor microenvironment in live mice.

AB Our previous study identified osteonectin (ON) in a screen of factors made by Schwann cells (SCs) which promoted peripheral and central neurons survival and neuritogenesis, however, the mechanisms of ON promoting effects are largely unknown. In the present study, we investigated the effects of ON-deficient SC-conditioned medium (SCCM) and molecular mechanisms of ON, in regulating retinal ganglion cells (RGCs) survival and neurite outgrowth. Neonatal rat RGCs and SCs were purified by immunopanning technique. RGC survival and neuritogenesis reduced significantly when treated with either ON-null mice SCCM or ON-immunodepleted (IP) SCCM (P<0.05). In contrast to wild type SCCM, in the presence of a tyrosine kinase receptor (Trk) inhibitor (K252a), ON-null mice SCCM-induced neuritogenesis were further reduced by 24%. The Trk-mediated signaling pathways became more sensitive to K252a inhibition in the absence of ON. We also showed the synergistic effects of ON and brain-derived neurotrophic factor (BDNF) in promoting RGCs growth and the involvement of ON in two major neurotrophin-mediated signaling pathways, PI-3K-Akt and MAPK-Erk1/2. ON alone activated Akt phosphorylation and increased survival. Blockage of TrkB signalling pathway by TrkB-Fc chimera (BDNF scavenger) or K252a in ON-treated cultures reduced Akt-P level significantly. This suggests that ON induces BDNF synthesis and secretion from RGCs. The enhancement of neuritogenesis and Erk1/2 phosphorylation by ON in BDNF-treated cultures further demonstrate the signaling pathways responsible for the synergistic effect of ON on BDNF-induced neurite outgrowth. To the best of our knowledge, this is the first report showing the synergistic effects of ON on classical neurotrophins which participate in the same signalling pathways in regulating RGC neurite outgrowth.

AB Hematopoietic stem cells (HSC) are rare, multipotent cells capable of generating all specialized cells of the blood system. Appropriate regulation of HSC quiescence is thought to be crucial to maintain their lifelong function; however, the molecular pathways controlling stem cell quiescence remain poorly characterized. Likewise, the molecular events driving leukemogenesis remain elusive. In this study, we compare the gene expression profiles of steady-state bone marrow HSC to non-self-renewing multipotent progenitors; to HSC treated with mobilizing drugs that expand the HSC pool and induce egress from the marrow; and to leukemic HSC in a mouse model of chronic myelogenous leukemia. By intersecting the resulting lists of differentially regulated genes we identify a subset of molecules that are downregulated in all three circumstances, and thus may be particularly important for the maintenance and function of normal, quiescent HSC. These results identify potential key regulators of HSC and give insights into the clinically important processes of HSC mobilization for transplantation and leukemic development from cancer stem cells.

AB Neutralizing antibody (nAb) response is sporadic and has limited potency and breadth during infection with human immunodeficiency virus type 1 (HIV-1). In rare cases, broad and potent nAbs are actually induced in vivo. Identifying specific epitopes targeted by such broad and potent nAb response is valuable in guiding the design of a prophylactic vaccine aimed to induce nAb. In this study, we have defined neutralizing epitope usage in 7 out of 17 subjects with broad and potent nAbs by using targeted mutagenesis in known neutralizing epitopes of HIV-1 glycoproteins and by using in vitro depletion of serum neutralizing activity by various recombinant HIV-1 glycoproteins. Consistent with recent reports, the CD4 binding site (CD4BS) is targeted by nAbs in vivo (4 of the 7 subjects with defined neutralizing epitopes). The new finding from this study is that epitopes in the gp120 outer domain are also targeted by nAbs in vivo (5 of the 7 Subjects), The outer domain epitopes include glycan-dependent epitopes (2 Subjects), conserved nonlinear epitope in the V3 region (2 Subjects), and a CD4BS epitope composed mainly of the elements in the outer domain ( I subject). Importantly, we found indication for epitope poly-specificity, a dual usage of the V3 and CD4BS epitopes, in only one subject. This study provides a more complete profile of epitope usage for broad and potent nAb responses during HIV-1 infection. (C) 2009 Elsevier Inc. All rights reserved.

AB BACKGROUND: Cellular proliferation, driven by cyclin-dependent kinases (CDKs) and their cyclin partners, is deregulated in cancer. Anti-estrogens, such as tamoxifen, antagonise estrogen-induced ER alpha transactivation of cyclin D1, resulting in reduced CDK4/6 activity, p27(Kip1)-mediated inhibition of CDK2 and growth arrest. We hypothesised that direct inhibition of CDK2 and CDK1 may overcome the major clinical problem of anti-estrogen resistance.
METHODS: The cellular effects of CDK2/1 siRNA knockdown and purine-based CDK2/1 inhibitors, NU2058 and NU6102, were measured in anti-estrogen-sensitive and resistant breast cancer cell lines.
RESULTS: CDK2 knockdown caused G1 accumulation, whereas CDK1 depletion caused G2/M slowing, and dual CDK1/2 depletion resulted in further G2/M accumulation and cell death in both anti-estrogen-sensitive and resistant cells, confirming CDK2 and CDK1 as targets for breast cancer therapy. In contrast to tamoxifen, which only affected hormone-sensitive cells, NU2058 and NU6102 reduced CDK2-mediated phosphorylation of pRb, E2F transcriptional activity and proliferation, ultimately resulting in cell death, in both anti-estrogen-sensitive and resistant cells. Both drugs caused G2/M arrest, reflective of combined CDK2/1 knockdown, with a variable degree of G1 accumulation.
CONCLUSION: These studies confirm the therapeutic potential of CDK2 and CDK1 inhibitors for cancer therapy, and support their use as an alternative treatment for endocrine-resistant breast cancer.

FAMILY; TUMORIGENESIS; METASTASIS; ACTIVATION; PHENOTYPE
AB BACKGROUND: Epithelial-to-mesenchymal transition (EMT) is associated with decreased adhesion and acquisition of metastatic potential of breast cancer cells. Epithelial-to-mesenchymal transition is mediated, in part, by two transcription repressors, Snail and Slug, that are known to be targets of the Notch signaling pathway, and JAGGED1-induced Notch activation increases EMT. However, the events that lead to increased Notch activity during EMT of breast cancer cells are unknown.
METHODS: The accumulation of hypoxia inducible factors (HIFs) under hypoxia was detected by western blot analysis, and their effects on Notch signaling were measured by an in vitro Notch reporter assay. The expression of Notch target genes under hypoxia was tested by real-time PCR. The knockdown of HIF-1 alpha was mediated by retroviral delivery of shRNA. The expression of Slug and Snail under hypoxia was measured by real-time PCR. Breast cancer cell migration and invasion under hypoxia were tested with cell migration and invasion kits.
RESULTS: Hypoxia increased the expression of Notch target genes such as HES1 and HEY1 in breast cancer cells, as was expression of Notch receptors and ligands. The mechanism is likely to involve the accumulation of HIF-1 alpha and HIF-2 alpha in these cells by hypoxia, which synergised with the Notch co-activator MAML1 in potentiating Notch activity. Hypoxia inducible factor-1 alpha was found to bind to HES1 promoter under hypoxia. Knockdown of HIF-1 alpha with shRNA inhibited both HES1 and HEY1 expression under hypoxia. Hypoxia increased the expression of Slug and Snail, and decreased the expression of E-cadherin, hallmarks of EMT. Notch pathway inhibition abrogated the hypoxia-mediated increase in Slug and Snail expression, as well as decreased breast cancer cell migration and invasion.
CONCLUSION: Hypoxia-mediated Notch signaling may have an important role in the initiation of EMT and subsequent potential for breast cancer metastasis.

AB MET amplification activates ERBB3/PI3K/AKT signaling in EGFR mutant lung cancers and causes resistance to EGFR kinase inhibitors. We demonstrate that MET activation by its ligand, HGF, also induces drug resistance, but through GAB1 signaling. Using high-throughput FISH analyses in both cell lines and in patients with lung cancer, we identify subpopulations; of cells with MET amplification prior to drug exposure. Surprisingly, HGF accelerates the development of MET amplification both in vitro and in vivo. EGFR kinase inhibitor resistance, due to either MET amplification or autocrine HGF production, was cured in vivo by combined EGFR and MET inhibition. These findings highlight the potential to prospectively identify treatment naive, patients with EGFR-mutant lung cancer who will benefit from initial combination therapy.

AB The Cancer Genome Atlas Network recently cataloged recurrent genomic abnormalities in glioblastoma multiforme (GBM). We describe a robust gene expression-based molecular classification of GBM into Proneural, Neural, Classical, and Mesenchymal subtypes and integrate multidimensional genomic data to establish patterns of somatic mutations and DNA copy number. Aberrations and gene expression of EGFR, NF1, and PDGFRA/IDH1 each define the Classical, Mesenchymal, and Proneural subtypes, respectively. Gene signatures of normal brain cell types show a strong relationship between subtypes and different neural lineages. Additionally, response to aggressive therapy differs by subtype, with the greatest benefit in the Classical subtype and no benefit in the Proneural subtype. We provide a framework that unifies transcriptomic and genomic dimensions for GBM molecular stratification with important implications for future studies.

AB Background-Biomarkers of multiple pathophysiological pathways have been related to incident atrial fibrillation (AF), but their predictive ability remains controversial.
Methods and Results-In 3120 Framingham cohort participants (mean age 58.4 +/- 9.7 years, 54% women), we related 10 biomarkers that represented inflammation (C-reactive protein and fibrinogen), neurohormonal activation (B-type natriuretic peptide [BNP] and N-terminal proatrial natriuretic peptide), oxidative stress (homocysteine), the renin-angiotensin-aldosterone system (renin and aldosterone), thrombosis and endothelial function (D-dimer and plasminogen activator inhibitor type 1), and microvascular damage (urinary albumin excretion; n = 2673) to incident AF (n = 209, 40% women) over a median follow-up of 9.7 years (range 0.05 to 12.8 years). In multivariable-adjusted analyses, the biomarker panel was associated with incident AF (P<0.0001). In stepwise-selection models (P<0.01 for entry and retention), log-transformed BNP (hazard ratio per SD 1.62, 95% confidence interval 1.41 to 1.85, P<0.0001) and C-reactive protein (hazard ratio 1.25, 95% confidence interval 1.07 to 1.45, P<0.004) were chosen. The addition of BNP to variables recently combined in a risk score for AF increased the C-statistic from 0.78 (95% confidence interval 0.75 to 0.81) to 0.80 (95% confidence interval 0.78 to 0.83) and showed an integrated discrimination improvement of 0.03 (95% confidence interval 0.02 to 0.04, P<0.0001), with 34.9% relative improvement in reclassification analysis. The combined analysis of BNP and C-reactive protein did not appreciably improve risk prediction over the model that incorporated BNP in addition to the risk factors.
Conclusions-BNP is a predictor of incident AF and improves risk stratification based on well-established clinical risk factors. Whether knowledge of BNP concentrations may be used to target individuals at risk of AF for more intensive monitoring or primary prevention requires further investigation.

AB Background-Smoking cessation is a key component of secondary cardiovascular disease prevention. Varenicline, a partial alpha 4 beta 2 nicotinic acetylcholine receptor agonist, is effective for smoking cessation in healthy smokers, but its efficacy and safety in smokers with cardiovascular disease are unknown.
Methods and Results-A multicenter, randomized, double-blind, placebo-controlled trial compared the efficacy and safety of varenicline with placebo for smoking cessation in 714 smokers with stable cardiovascular disease. Participants received varenicline (1 mg twice daily) or placebo, along with smoking-cessation counseling, for 12 weeks. Follow-up lasted 52 weeks. The primary end point was carbon monoxide-confirmed continuous abstinence rate for weeks 9 through 12 (last 4 weeks of treatment). The continuous abstinence rate was higher for varenicline than placebo during weeks 9 through 12 (47.0% versus 13.9%; odds ratio, 6.11; 95% confidence interval [CI], 4.18 to 8.93) and weeks 9 through 52 (19.2% versus 7.2%; odds ratio, 3.14; 95% CI, 1.93 to 5.11). The varenicline and placebo groups did not differ significantly in cardiovascular mortality (0.3% versus 0.6%; difference, -0.3%; 95% CI, -1.3 to 0.7), all-cause mortality (0.6% versus 1.4%; difference, -0.8%; 95% CI, -2.3 to 0.6), cardiovascular events (7.1% versus 5.7%; difference, 1.4%; 95% CI, -2.3 to 5.0), or serious adverse events (6.5% and 6.0%; difference, 0.5%; 95% CI, -3.1 to 4.1). As a result of adverse events, 9.6% of varenicline and 4.3% of placebo participants discontinued study drug.
Conclusions-Varenicline is effective for smoking cessation in smokers with cardiovascular disease. It was well tolerated and did not increase cardiovascular events or mortality; however, trial size and duration limit definitive conclusions about safety.

AB Cell polarity proteins regulate tight junction formation and directional migration in epithelial cells. To date, the mechanism by which these polarity proteins assemble at the leading edge of migrating epithelial cells remains unclear. We report that occludin, a transmembrane protein, is localized at the leading edge of migrating cells and regulates directional cell migration. During migration, occludin knockdown disrupted accumulation of aPKC-Par3 and PATJ at the leading edge, and led to a disorganized microtubule network and defective reorientation of the microtubule organization center (MTOC). Phosphorylation of occludin at tyrosine 473 residue allowed recruitment of p85 alpha to the leading edge via association with its C-terminal SH2 domain. Loss of occludin attenuated activation of PI3K, leading to disorganization of the actin cytoskeleton and reduced cell protrusions. Our data indicate that occludin is required for the leading-edge localization of polarity proteins aPKC-Par3 and PATJ and promotes cell protrusion by regulating membrane-localized activation of PI3K.

AB Advances in genome analysis, network biology, and computational chemistry have the potential to revolutionize drug discovery by combining system-level identification of drug targets with the atomistic modeling of small molecules capable of modulating their activity. To demonstrate the effectiveness of such a discovery pipeline, we deduced common antibiotic targets in Escherichia coli and Staphylococcus aureus by identifying shared tissue-specific or uniformly essential metabolic reactions in their metabolic networks. We then predicted through virtual screening dozens of potential inhibitors for several enzymes of these reactions and showed experimentally that a subset of these inhibited both enzyme activities in vitro and bacterial cell viability. This blueprint is applicable for any sequenced organism with high-quality metabolic reconstruction and suggests a general strategy for strain-specific antiinfective therapy.

AB The mechanisms underlying tumoral secretion of signaling molecules into the microenvironment, which modulates tumor cell fate, angiogenesis, invasion, and metastasis, are not well understood. Aberrant expression of transcription factors, which has been implicated in the tumorigenesis of several types of cancers, may provide a mechanism that induces the expression of growth and angiogenic factors in tumors, leading to their local increase in the tumor microenvironment, favoring tumor progression. In this report, we demonstrate that the transcription factor HOXB9 is overexpressed in breast carcinoma, where elevated expression correlates with high tumor grade. HOXB9 induces the expression of several angiogenic factors (VEGF, bFGF, IL-8, and ANGPTL-2), as well as ErbB (amphiregulin, epiregulin, and neuregulins) and TGF-beta, which activate their respective pathways, leading to increased cell motility and acquisition of mesenchymal phenotypes. In vivo, HOXB9 promotes the formation of large, well-vascularized tumors that metastasize to the lung. Thus, deregulated expression of HOXB9 contributes to breast cancer progression and lung metastasis by inducing several growth factors that alter tumor-specific cell fates and the tumor stromal microenvironment.

AB The viral spike of HIV-1 is composed of three gp120 envelope glycoproteins attached noncovalently to three gp41 transmembrane molecules. Viral entry is initiated by binding to the CD4 receptor on the cell surface, which induces large conformational changes in gp120. These changes not only provide a model for receptor-triggered entry, but affect spike sensitivity to drug-and antibody-mediated neutralization. Although some of the details of the CD4-induced conformational change have been visualized by crystal structures and cryoelectron tomograms, the critical gp41-interactive region of gp120 was missing from previous atomic-level characterizations. Here we determine the crystal structure of an HIV-1 gp120 core with intact gp41-interactive region in its CD4-bound state, compare this structure to unliganded and antibody-bound forms to identify structurally invariant and plastic components, and use ligand-oriented cryoelectron tomograms to define component mobility in the viral spike context. Newly defined gp120 elements proximal to the gp41 interface complete a 7-stranded beta-sandwich, which appeared invariant in conformation. Loop excursions emanating from the sandwich form three topologically separate-and structurally plastic-layers, topped off by the highly glycosylated gp120 outer domain. Crystal structures, cryoelectron tomograms, and interlayer chemistry were consistent with a mechanismin which the layers act as a shape-changing spacer, facilitating movement between outer domain and gp41-associated beta-sandwich and providing for conformational diversity used in immune evasion. A "layered" gp120 architecture thus allows movement among alternative glycoprotein conformations required for virus entry and immune evasion, whereas a beta-sandwich clamp maintains gp120-gp41 interaction and regulates gp41 transitions.

RNA; ASSOCIATIONS; LYMPHOCYTES; EXPRESSION; CHALLENGE
AB Retroviruses pack multiple genes into relatively small genomes by encoding several genes in the same genomic region with overlapping reading frames. Both sense and antisense HIV-1 transcripts contain open reading frames for known functional proteins as well as numerous alternative reading frames (ARFs). At least some ARFs have the potential to encode proteins of unknown function, and their antigenic properties can be considered as cryptic epitopes (CEs). To examine the extent of active immune response to virally encoded CEs, we analyzed human leukocyte antigen class I-associated polymorphisms in HIV-1 gag, pol, and nef genes from a large cohort of South Africans with chronic infection. In all, 391 CEs and 168 conventional epitopes were predicted, with the majority (307; 79%) of CEs derived from antisense transcripts. In further evaluation of CD8 T cell responses to a subset of the predicted CEs in patients with primary or chronic infection, both sense- and antisense-encoded CEs were immunogenic at both stages of infection. In addition, CEs often mutated during the first year of infection, which was consistent with immune selection for escape variants. These findings indicate that the HIV-1 genome might encode and deploy a large potential repertoire of unconventional epitopes to enhance vaccine-induced antiviral immunity.

Using host genetic (human leukocyte antigen [HLA]) and plasma viral sequence information from 765 HIV-infected subjects, we identified 64 statistically significant (q < 0.2) associations between specific HLA alleles and sequence polymorphisms in alternate reading frames of gag, pol, and nef that did not affect the regular frame protein sequence. Peptides spanning the top 20 HLA-associated imprints were used to test for ex vivo immune responses in 85 HIV-infected subjects and showed responses to 10 of these ARF peptides. The most frequent response recognized an HLA-A*03-restricted +2 frame-encoded epitope containing a unique A*03-associated polymorphism at position 6. Epitope-specific CTLs efficiently inhibited viral replication in vitro when viruses containing the wild-type sequence but not the observed polymorphism were tested. Mutating alternative internal start codons abrogated the CTL-mediated inhibition of viral replication. These data indicate that responses to ARF-encoded HIV epitopes are induced during natural infection, can contribute to viral control in vivo, and drive viral evolution on a population level.

AB Recent advances in the synthesis of polymeric colloids have opened the doors to new advanced materials. There is strong interest in using these new techniques to produce particles that mimic and/or interact with biological systems. An important characteristic of biological systems that has not yet been exploited in synthetic polymeric colloids is their wide range of deformability. A canonical example of this is the human red blood cell (RBC) which exhibits extreme reversible deformability under flow. Here we report the synthesis of soft polymeric colloids with sizes and shapes that mimic those of the RBC. Additionally, we demonstrate that the mechanical flexibility of the colloids can be reproducibly varied over a large range resulting in RBC-like deformability under physiological flow conditions. These materials have the potential to impact the interaction between biological and synthetic systems.

AB Optodes have been used for detection of ionic concentrations and fluxes for several years. However, their uses in biomedical applications have not yet been fully explored. This study investigates optodes as a potential sensor platform for monitoring cellular ion flux with attendant implications in the field of drug screening and toxicology. A prototype system was developed to quantitatively measure extracellular potassium flux from a monolayer of cardiomyocytes. Optodes were created and immobilized on a glass coverslip for fluorescent imaging. The system detected potassium (K(+)) ion flux during the repolarization phase of the cardiac action potential and further detected a decrease in the magnitude of the flux in the presence of a known K(+) channel inhibitor by optically monitoring local K(+) ion concentrations during field stimulation of the cardiomyocyte monolayer.

Australian perspective

ID PEDIATRIC PALLIATIVE CARE; HOME-CARE; DYING CHILDREN; CIRCUMSTANCES;

AB Objective: To examine the symptoms, level of suffering, and care of Australian children with cancer at the end of life.
Design, setting and participants: In a study conducted at the Royal Children's Hospital, Melbourne, parents of children who had died of cancer over the period 1996-2004 were interviewed between February 2004 and August 2006. Parents also completed and returned self-report questionnaires.
Main outcome measures: Proportions of children suffering from and treated for various symptoms; proportion of children receiving cancer-directed therapy at the end of life; proportion of children whose treatment of symptoms was successful; location of death.
Results: Of 193 eligible families, 96 (50%) were interviewed. All interviews were conducted in person, and occurred a mean of 4.5 years (SD, 2.1 years) after the child's death. Eighty-four per cent of parents reported that their child had suffered "a lot" or "a great deal" from at least one symptom in their last month of life - most commonly pain (46%), fatigue (43%) and poor appetite (30%). Children who received cancer-directed therapy during the end-of-life period (47%) suffered from a greater number of symptoms than those who did not receive treatment (P = 0.03), but the severity of symptoms did not differ between these groups. Of the children treated for specific symptoms, treatment was successful in 47% of those with pain, 18% of those with fatigue and 17% of those with poor appetite. Of the 61 families who felt they had time to plan where their child would die, 89% preferred to have their child die at home. The majority of children (61%) died at home. Of those who died in hospital, less than a quarter died in the intensive care unit.
Conclusions: Relatively high rates of death at home and low rates of unsuccessful medical interventions suggest a realistic approach at the end of life for Australian children dying of cancer. However, many suffer from unresolved symptoms, and greater attention should be paid to palliative care for these children. MJA 2010; 192: 71-75

AB Sleep fragmentation (SF) impairs the restorative/cognitive benefits of sleep via as yet unidentified alterations in neural physiology. Previously,we found that hippocampal synaptic plasticity and spatial learning are impaired in a rat model of SF which utilizes a treadmill to awaken the animals every 2 min, mimicking the frequency of awakenings observed in human sleep apnea patients. Here, we investigated the cellular mechanisms responsible for these effects, using whole-cell patch-clamp recordings. 24 h of SF decreased the excitability of hippocampal CA1 pyramidal neurons via decreased input resistance, without alterations in other intrinsic membrane or action potential properties (when compared to cage controls, or to exercise controls that experienced the same total amount of treadmill movement as SF rats). Contrary to our initial prediction, the hyperpolarizing response to bath applied adenosine (30 mu M) was reduced in the CA1 neurons of SF treated rats. Our initial prediction was based on the evidence that sleep loss upregulates cortical adenosine A1 receptors; however, the present findings are consistent with a very recent report that hippocampal A1 receptors are not elevated by sleep loss. Thus. increased adenosinergic inhibition is unlikely to be responsible for reduced hippocampal long-term potentiation in SF rats. Instead, the reduced excitability of CA1 pyramidal neurons observed here may contribute to the loss of hippocampal long-term potentiation and hippocampus-dependent cognitive impairments associated with sleep disruption.

AB We describe a new method for imaging leukocytes in vivo by exciting the endogenous protein fluorescence in the ultraviolet (UV) spectral region where tryptophan is the major fluorophore. Two-photon excitation near 590 nm allows noninvasive optical sectioning through the epidermal cell layers into the dermis of mouse skin, where leukocytes can be observed by video-rate microscopy to interact dynamically with the dermal vascular endothelium. Inflammation significantly enhances leukocyte rolling, adhesion, and tissue infiltration. After exiting the vasculature, leukocytes continue to move actively in tissue as observed by time-lapse microscopy, and are distinguishable from resident autofluorescent cells that are not motile. Because the new method alleviates the need to introduce exogenous labels, it is potentially applicable for tracking leukocytes and monitoring inflammatory cellular reactions in humans.

AB P>Background
The status and determinants of health-related quality of life (HRQOL) in female veterans with and without irritable bowel syndrome (IBS) are unknown.
Aim
To compare HRQOL in female veterans with and without IBS symptoms and examine the contribution of post-traumatic stress disorder, depression and anxiety to HRQOL.
Methods
A cross-sectional study of 339 female veterans. Self-report questionnaires were used to evaluate IBS symptoms, post-traumatic stress disorder, depression, anxiety and HRQOL.
Results
Symptoms consistent with IBS were present in 33.5% of participants. Female veterans with IBS symptoms had significant reductions in physical component score and 5 of 8 Health Related Quality of Life subscales and on 7 of 8 Irritable Bowel Syndrome Quality Of Life subscales than female veterans without IBS symptoms. Compared with the US general female population, female veterans had significantly lower Health Related Quality of Life physical component score and mental component scores (MCS) irrespective of IBS symptom status. Differences in the MCS score were most explained by depression, while those in the physical component score were most explained by anxiety.
Conclusions
Irritable bowel syndrome symptoms in female veterans are associated with considerable reduction in HRQOL. However, female veterans, regardless of IBS symptom status, have lower HRQOL compared with the general US female population.

AB P>Background
Despite advances in cross-sectional imaging and the use of molecular markers, distinguishing between benign and malignant cysts remains a clinical challenge.
Aims
To identify both preoperative clinical and cyst characteristics at the time of EUS that predict malignancy.
Methods
A retrospective analysis was performed on consecutive patients with pancreatic cysts who underwent endoscopic ultrasound (EUS) and surgical resection from May 1996 to December 2007 at a tertiary centre. Clinical history, EUS characteristics, cytology, tumour markers and surgical histology were collected. Predictors of malignancy were determined by univariate and multivariate analysis using logistic regression.
Results
A total of 153 patients underwent a EUS and subsequent surgical intervention.Of the 153 patients, 57 (37%) had a histological diagnosis of malignancy. On univariate analysis, older age (P < 0.001), male gender (P = 0.010), jaundice (P = 0.039), history of other malignancy (P = 0.036), associated mass in cyst (P = 0.004) and malignant cytology (P < 0.001) were found to be associated with malignancy. History of pancreatitis (P = 0.008) and endoscopist impression of pseudocyst (P = 0.001) were found to be associated with benign cysts. Multivariate analysis found that only older age [Odds ratio (OR), 1.04; 95% confidence interval (CI), 1.01-1.08], male gender (OR, 2.26; 95% CI, 1.08-4.73) and malignant cytology (OR, 6.60; 95% CI, 2.02-21.58) were independent predictors of malignancy.
Conclusions
Older age, male gender and malignant cytology from EUS predict malignancy at surgical resection. These characteristics may be used to estimate the probability of malignancy in a cyst and aid in management.

AB P>Background
Wireless pH and pressure motility capsule (wireless motility capsule) technology provides a method to assess regional gastrointestinal transit times.
Aims
To analyse data from a multi-centre study of gastroparetic patients and healthy controls and to compare regional transit times measured by wireless motility capsule in healthy controls and gastroparetics (GP).
Methods
A total of 66 healthy controls and 34 patients with GP (15 diabetic and 19 idiopathic) swallowed wireless motility capsule together with standardized meal (255 kcal). Gastric emptying time (GET), small bowel transit time (SBTT), colon transit time (CTT) and whole gut transit time (WGTT) were calculated using the wireless motility capsule.
Results
Gastric emptying time, CTT and WGTT but not SBTT were significantly longer in GP than in controls. Eighteen percent of gastroparetic patients had delayed WGTT. Both diabetic and idiopathic aetiologies of gastroparetics had significantly slower WGTT (P < 0.0001) in addition to significantly slower GET than healthy controls. Diabetic gastroparetics additionally had significantly slower CTT than healthy controls (P = 0.0054).
Conclusions
In addition to assessing gastric emptying, regional transit times can be measured using wireless motility capsule. The prolongation of CTT in gastroparetic patients indicates that dysmotility beyond the stomach in GP is present, and it could be contributing to symptom presentation.

AB Myocardial infarct (MI) size is a well-established prognostic marker but the association of serum markers with MI size, as measured by myocardial perfusion imaging (MPI), has not been well studied in patients with hypertrophic cardiomyopathy (NC) after alcohol septal ablation (ASA). Creatine kinase (CK), CK-MB, troponin I, and brain natriuretic peptide were measured before and at multiple points after ASA in patients with HC and were correlated with MI size measured by MPI. MPI at rest was performed in 54 patients with HC at a median of 2 days after ASA. CK, CK-MB, and troponin I increased after ASA to peak levels at 12 hours and their cumulative levels (area under the curve) showed significant correlation with size of MI by MPI (r = 0.544, 0.408, and 0.477, p <0.001, 0.003, and 0.001, respectively). The best marker was level of CK at 12 hours (r = 0.609, p <0.0001) after ASA. Brain natriuretic peptide level did not change significantly after ASA (p = 1.0) and only weakly correlated with MI size by MPI (r = 0.130, p = 0.007). In conclusion, CK, CK-MB, and troponin I measured at 12 hours, at peak, and as the area under the curve correlated well with infarct size, but CK level at 12 hours was the best marker. CK continues to be a useful marker of MI size despite the introduction of newer, more specific markers, especially when infarct onset is known with certainty as in patients with HC undergoing ASA.

AB Many studies have investigated the relation between magnesium and iron intake and diabetes and, separately, between diabetes and pancreatic cancer. However, no known study has examined the direct association of magnesium and iron intake with pancreatic cancer risk. The authors obtained magnesium and iron intake data using food frequency questionnaires from the US male Health Professionals Follow-up Study, which began in 1986. During 851,476 person-years and 20 years of follow-up, 300 pancreatic cancer cases were documented. Cox proportional hazards models were used to estimate relative risks, adjusting for age, smoking, and body mass index. No associations were observed between magnesium or iron intake and pancreatic cancer (highest vs. lowest quintile: relative risk (RR) = 0.94, 95% confidence interval (CI): 0.66, 1.32 and RR = 0.93, 95% CI: 0.65, 1.34, respectively). Similarly, iron or magnesium supplement use was not related to pancreatic cancer. A statistically significant inverse relation was noted between magnesium and pancreatic cancer for subjects with a body mass index of >= 25 kg/m(2) (RR = 0.67, 95% CI: 0.46, 0.99; P-trend = 0.04). Although, overall, no relation between magnesium or iron intake and pancreatic cancer was observed in this cohort of men, an inverse association with magnesium was suggested among overweight individuals, which should be examined in other studies.

AB The low concentration and complex sample matrix of many clinical and environmental viral samples presents a significant challenge in the development of low cost, point-of-care viral assays. To address this problem, we investigated the use of a microfluidic passive magnetic separator combined with on-chip mixer to both purify and concentrate whole-particle human immunodeficiency virus type 1 (HIV-1) virions. Virus-containing plasma samples are first mixed to allow specific binding of the viral particles with antibody-conjugated superparamagnetic nanoparticles, and several passive mixer geometries were assessed for their mixing efficiencies. The virus-nanoparticle complexes are then separated from the plasma in a novel magnetic separation chamber, where packed micrometer-sized ferromagnetic particles serve as high magnetic gradient concentrators for an externally applied magnetic field. Thereafter, a viral lysis buffer was flowed through the chip and the released HIV proteins were assayed off-chip. Viral protein extraction efficiencies of 62% and 45% were achieved at 10 and 30 mu L/min throughputs, respectively. More importantly, an 80-fold concentration was observed for an initial sample volume of 1 mL and a 44-fold concentration for an initial sample volume of 0.5 mL. The system is broadly applicable to microscale sample preparation of any viral sample and can be used for nucleic acid extraction as well as 40-80-fold enrichment of target viruses.

AB Endotoxemia plays an important role in the pathogenesis of sepsis and is accompanied by dysregulated apoptosis of immune and non-immune cells. Treatment with statins reduces mortality in rodent models of sepsis and endotoxemia. Inhibition of protein isoprenylation, including farnesylation, has been proposed as a mechanism to mediate the lipid-lowering-independent effects of statins. Nonetheless, the effects of the inhibition of isoprenylation have not yet been studied. To investigate the role of farnesylation, we evaluated the effects of farnesyltransferase inhibitor and statin on survival following lipopolysaccharide (LPS) challenge in mice. Both simvastatin (2 mg/kg BW) and FTI-277 (20 mg/kg BW) treatment improved survival by twofold after LPS injection, as compared with vehicle alone (p < 0.01). LPS-induced cleavage (activation) of caspase-3, an indicator of apoptotic change, and increased protein expression of proapoptotic molecules, Bax and Bim, and activation of c-Jun NH(2)-terminal kinase (JNK/SAPK) in the liver and spleen were attenuated by both simvastatin and FTI-277. These results demonstrate that farnesyltransferase inhibitor as well as statin significantly reduced LPS-induced mortality in mice. Our findings also suggest that inhibition of protein farnesylation may contribute to the lipid-lowering-independent protective effects of statins in endotoxemia, and that protein farnesylation may play a role in LPS-induced stress response, including JNK/SAPK activation, and apoptotic change. Our data argue that farnesyltransferase may be a potential molecular target for treating patients with endotoxemia. (c) 2009 Elsevier Inc. All rights reserved.

AB Background: Treatment-resistant depression presents a serious challenge to both patients and clinicians. The anterior and midlateral prefrontal cortices play complementary roles in integrating emotional and cognitive experiences and in modulating subcortical regions. Both regions offer a distinct opportunity for targeted antidepressant treatments. We chose to pilot the safety and therapeutic benefits of chronic and intermittent epidural prefrontal cortical stimulation (EpCS) in patients with treatment-resistant depression.
Methods: We enrolled five adults with an average of 5.8 failed antidepressant treatments in their current depressive episode. All subjects underwent comprehensive clinical assessments, detailed neuropsychological testing, and presurgical magnetic resonance imaging. Four cortical stimulation paddle leads were stereotactically placed bilaterally over the anterior frontal poles and midlateral prefrontal cortex. We also acquired a postsurgical computed tomography scan and repeatedly assessed clinical outcomes over time of EpCS as an adjunctive treatment to constant medications.
Results: All patients tolerated the therapy. At 7-month follow-up, the average improvement from preimplant baseline on the Hamilton Rating Scale for Depression and the Inventory of Depressive Symptoms-Self-Report were 54.9% (+/- 37.7) and 60.1% (+/- 34.1), respectively. Three implanted subjects reached remission. One patient's left hemisphere leads were explanted 12 weeks postsurgery because of a scalp infection.
Conclusions: Bilateral EpCS over anterior and mid lateral frontal cortex is a promising new technology for treatment-resistant depression. Future double-blind studies are warranted.

AB BACKGROUND: Young adult survivors of childhood cancer have an increased risk for treatment-related morbidity and mortality. In this study, the authors assessed how treatment for childhood cancer affects older-adult health and health practices. METHODS: One hundred seven adults treated for childhood cancer between 1947 and 1968, known to have survived past age 50 years, were identified from a single-institution cohort established in 1975. Updated vital status on eligible cases was obtained from public records. Survivors and a control group of their age-matched siblings and cousins completed a mailed survey to assess physical and social function, healthcare practices, and the prevalence of common adult illnesses. RESULTS: Of the 107 survivors known to be alive at age 50 years, 16 were deceased at follow-up; 7 deaths could be associated with prior treatment (second malignancy in radiation field [3], small bowel obstruction after abdominal radiation [2], and cardiac disease after chest irradiation [2]). The 55 survivors (median age, 56 years; range, 51-71 years), and 32 family controls (median age, 58 years; range, 48-70 years), reported similar health practices, health-related quality of life, and social function. However, survivors reported more frequent visits to healthcare providers (P < .05), more physical impairments (P < .05), fatigue (P = .02), hypertension (P = .001), and coronary artery disease (P = .01). An increased risk of hypertension was associated with nephrectomy during childhood (odds ratio, 18.9; 95% confidence interval, 3.0-118.8). CONCLUSIONS: The oldest adult survivors of childhood cancer continue to be at risk for treatment-related complications that potentially decrease their life expectancy and compromise their quality of life.

AB Personalized cancer risk assessment remains an essential imperative in postgenomic cancer medicine. In hereditary melanoma, germline CDKN2A mutations have been reproducibly identified in melanoma-prone kindreds worldwide. However, genetic risk counseling for hereditary melanoma remains clinically challenging. To address this challenge, we developed and validated MelaPRO, an algorithm that provides germline CDKN2A mutation probabilities and melanoma risk to individuals from melanoma-prone families. MelaPRO builds on comprehensive genetic information, and uses Mendelian modeling to provide fine resolution and high accuracy. In an independent validation of 195 individuals from 167 families, MelaPRO exhibited good discrimination with a concordance index (C) of 0.86 [95% confidence intervals (95% CI), 0.75-0.97] and good calibration, with no significant difference between observed and predicted carriers (26; 95% CI, 20-35, as compared with 22 observed). In cross-validation, MelaPRO outperformed the existing predictive model MELPREDICT (C, 0.82; 95% CI, 0.61-0.93), with a difference of 0.05 (95% CI, 0.007-0.17). MelaPRO is a clinically accessible tool that can effectively provide personalized risk counseling for all members of hereditary melanoma families. Cancer Res; 70(2); 552-9. (C)2010 AACR.

AB Clear cell sarcoma (CCS), a childhood tumor of the tendons and aponeuroses, is uniformly fatal once it has metastasized because of its profound therapeutic resistance. CCS is characterized by production of a chimeric transcription factor, EWS-ATF1, which is formed as the result of a disease-specific chromosomal translocation. EWS-ATF1 activates the melanocyte transcription factor MITF, which in turn activates transcription of c-Met, an oncogenic receptor tyrosine kinase recently shown to be activated in CCS. Based on this connection, we hypothesized that c-Met inhibition may offer a strategy to treat CCS, as an indirect tactic to defeat a transforming pathway downstream of EWS-ATF1. Here, we show that primary CCS and CCS-derived cell lines express c-Met, which is activated in an autocrine fashion by its ligand hepatocyte growth factor (HGF)/scatter factor in some CCS cell lines. c-Met expression is critical for CCS invasion, chemotaxis, and survival. Blocking c-Met activity with a small-molecule inhibitor (SU11274) or a neutralizing antibody to its ligand HGF (AMG 102) significantly reduced CCS cell growth in culture. Similarly, AMG 102 significantly suppressed in vivo tumor growth in an autocrine xenograft model of CCS. Collectively, these findings suggest the HGF: c-Met signaling axis as a candidate therapeutic target to improve clinical management of CCS. Cancer Res; 70(2); 639-45. (C)2010 AACR.

AB Highly immunogenic cancers such as malignant melanoma are capable of inexorable tumor growth despite the presence of antitumor immunity. Thus, only a restricted minority of tumorigenic malignant cells may possess the phenotypic and functional characteristics needed to modulate tumor-directed immune activation. Here we provide evidence supporting this hypothesis. Tumorigenic ABCB5(+) malignant melanoma initiating cells (MMICs) possessed the capacity to preferentially inhibit IL-2-dependent T-cell activation and to support, in a B7.2-dependent manner, induction of CD4(+)CD25(+)FoxP3(+) regulatory T cells (Tregs). Compared with melanoma bulk cell populations, ABCB5(+) MMICs displayed lower levels of MHC class I, aberrant positivity for MHC class II, and lower expression levels of the melanoma-associated antigens MART-1, ML-IAP, NY-ESO-1, and MAGE-A. Additionally, these tumorigenic ABCB5(+) subpopulations preferentially expressed the costimulatory molecules B7.2 and PD-1, both in established melanoma xenografts and in clinical tumor specimens. In immune activation assays, MMICs inhibited mitogen-dependent human peripheral blood mononuclear cell (PBMC) proliferation and IL-2 production more efficiently than ABCB5(-)melanoma cell populations. Moreover, coculture with ABCB5(+) MMICs increased the abundance of Tregs, in a B7.2 signaling-dependent manner, along with IL-10 production by mitogen-activated PBMCs. Consistent with these findings, MMICs also preferentially inhibited IL-2 production and induced IL-10 secretion by cocultured patient-derived, syngeneic PBMCs. Our findings identify novel T-cell modulatory functions of ABCB5(+) melanoma subpopulations and suggest specific roles for these MMICs in the evasion of antitumor immunity and in cancer immunotherapeutic resistance.

AB The critical downstream signaling consequences contributing to renal cancer as a result of loss of the tumor suppressor gene von Hippel-Lindau (VHL) have yet to be fully elucidated. Here, we report that VHL loss results in an epithelial to mesenchymal transition (EMT). In studies of paired isogenic cell lines, VHL silencing increased the levels of N-cadherin and vimentin and reduced the levels of E-cadherin relative to the parental VHL(+) cell line, which displayed the opposite profile. VHL(+) cells grew as clusters of cuboidal and rhomboid cells, whereas VHL-silenced cells took on an elongated, fibroblastoid morphology associated with a more highly invasive character in Matrigel chamber assays. Based on earlier evidence that VHL loss can activate NF-kappa B, a known mediator of EMT, we tested whether NF-kappa B contributed to VHL-mediated effects on EMT. On pharmacologic or molecular inhibition of NF-kappa B, VHL-silenced cells regained expression of E-cadherin, lost expression of N-cadherin, and reversed their highly invasive phenotype. Introducing a pVHL-resistant hypoxia-inducible factor 1 alpha (HIF1 alpha) mutant (HIF alpha(M)) into VHL(+) cells heightened NF-kappa B activity, phenocopying EMT effects produced by VHL silencing. Conversely, inhibiting the heightened NF-kappa B activity in this setting reversed the EMT phenotype. Taken together, these results suggest that VHL loss induces an EMT that is largely dependent on HIF alpha-induced NF-kappa B. Our findings rationalize targeting the NF-kappa B pathway as a therapeutic strategy to treat renal tumors characterized by biallelic VHL inactivation. Cancer Res; 70(2); 752-61. (C)2010 AACR.

AB A primary goal of genetic association studies is to elucidate genes and novel biological mechanisms involved in disease. Recently, genome-wide association studies have identified many common genetic variants that are significantly associated with complex diseases such as cancer. In contrast to Mendelian disorders, a sizable fraction of the variants lies outside known protein-coding regions; therefore, understanding their biological consequences presents a major challenge in human genetics. Here we describe an integrated framework to allow nonprotein coding loci to be annotated with respect to regulatory functions. This will facilitate identification of target genes as well as prioritize variants for functional testing.

AB The meiotic cell cycle is required for production of fertilization-competent gametes. Germ cell meiotic commitment requires expression of Stimulated by retinoic acid gene 8 (Stra8), which is transcriptionally activated by retinoic acid (RA). Meiotic suppression in embryonic male germ cells is believed to result from sex-specific differences in CYP26B1-catalyzed RA metabolism in the developing gonads. Here we show in mice that RA-induced Stra8 transcription is epigenetically controlled and requires a co-activator that binds proximal to the RA response elements (RAREs) in the Stra8 promoter. Embryonic male germ cells exposed in utero to the class I/II histone deacetylase (HDAC) inhibitor, trichostatin-A (TSA), show premature Stra8 activation and meiotic entry without altered Cyp26b1 expression. We also show that Stra8 expression is detectable and physiologically regulated in adult mouse ovaries. Further, oogenesis induction in adult females using TSA is associated with Stra8 activation, and these events are absent in mice deficient in the RA precursor vitamin A. Finally, all of the actions of TSA in premeiotic germ cells in vitro and in mouse ovaries in vivo can be reproduced with the small molecule HDAC inhibitor, suberoylanilide hydroxamic acid (SAHA). Thus, the ability of RA to transcriptionally induce expression of the meiosis-commitment gene, Stra8, is epigenetically controlled and this process involves a novel co-activator that functions upstream of the RAREs. These events not only coordinate the sex-specific timing of meiotic entry during embryogenesis, but also contribute to the regulation of oogenesis in adult female mammals.

AB Recent debate has addressed whether global health financing should prioritize interventions that maximize lives saved; focus on the young; and are most economically efficient (most cost-effective). In particular, some have argued that an expansion of the President's Emergency Plan for AIDS Relief (PEPfAR) is not the best use of international health funding, and that extending funding to treat diarrheal and respiratory disease could save more lives at substantially lower costs. We examine the methods of cost-effectiveness analysis and why their application, without context, may not be appropriate for priority setting in this fashion. We further address the substantial impact PEPfAR has achieved in general and more specifically toward improving maternal and child health and why continued PEPfAR investment remains essential.

AB Objective: To compare outcomes of frozen embryo transfer (FET) cycles when two or three embryos were transferred in women aged <40 years.
Design: Retrospective chart review.
Setting: A university-affiliated IVF program.
Patient(s): Women undergoing FET cycles between January 2004 and December 2005.
Intervention(S): Transfer of two or three embryos.
Main Outcome Measure(s): Clinical pregnancy rate (PR), multiple pregnancy rate (MPR), and live birth rate (LBR).
Result(s): In patients aged <35 (n = 145), two versus three embryo group had similar PR and LBR, but the MPR was significantly higher in the three-embryo group (41% for three embryos vs. 9.4% for two embryos). Clinical pregnancy in the fresh cycle from which the frozen embryos were obtained did not affect the PR, and an increase in MPR was still observed. In patients aged 35 to 39 (n = 93), there were no differences in the PR, MPR, or LBR between the two groups.
Conclusion(S): Transfer of two instead of three frozen embryos in patients <35 years old resulted in a significant decrease in MPR without compromising PR or LBR. Transferring additional embryos when a patient had an unsuccessful fresh cycle was not warranted. In the age group 35-39 years, transferring two instead of three embryos did not decrease PR or LBR, and had no effect on the risk of high-order multiples. (Fertil Steril (R) 2010;93:355-9.

Design: Retrospective case-control study.
Setting: Academic medical center.
Patient(S): The study population included 20 egg donor and 33 nondonor IVF pregnancies of >24 weeks' gestation.
Intervention(s): None.
Main Outcome Measure(s): Perinatal complications (gestational hypertension, abruption, preterm delivery, cesarean section), microscopic features indicating ail immune response and trophoblast damage, and characterization of inflammatory cells using immunohistochemistry.
Result(S): There was ail increase in gestational hypertension and preterm delivery in egg donor pregnancies. Dense fibrinoid deposition in the basal plate with severe chronic deciduitis containing significantly increased numbers of T helper and natural killer cells were demonstrated in egg donor placentas. Trophoblast damage was also increased in the preterm egg donor group.
Conclusion(S): There are significant histological and immunohistochemical differences between the placentas of egg donor and nondonor IVF pregnancies. The increased immune activity and fibrinoid deposition at the maternal-fetal interface of egg donor pregnancies Could represent a host versus graft rejection-like phenomenon.

AB Objective: To determine whether the use of GnRH antagonist in cycles converted from ovulation induction-IUI to IVF affects cycle outcome and, pregnancy rates.
Design: Retrospective cohort study.
Setting: Academic research institution.
Patient(s): One hundred eighty-two consecutive patients with ovulation induction-IUI to IVF conversions undergoing oocyte retrieval conducted at our institution from 2004 to 2006.
Intervention(s): The relation between observation of fetal heartbeat and GnRH antagonist exposure was evaluated with use of multivariable logistic regression. The difference in intermediate cycle outcomes by antagonist exposure was estimated with use of linear regression.
Main Outcome Measure(s): Fetal cardiac activity on early ultrasound, intermediate cycle parameters.
Result(s): For patients given treatment with a GnRH antagonist, the odds ratio for achieving pregnancy was 2.13 (95% confidence interval = 1.03-4.39) compared with untreated patients, independent of age and E(2) levels on day of hCG. Patients given antagonist had 1.6 more follicles and 2.1 more oocytes retrieved, 1.9 more mature oocytes, and 2.3 more fertilized oocytes, and the fertilization rate was 9.7% higher.
Conclusion(s): Gonadotropin-releasing hormone antagonist use in ovulation induction-IUI to IVF conversions was associated with increased pregnancy rates and improved intermediate cycle parameters, controlled for age and E(2) levels on day of hCG. Addition of a GnRH antagonist should be considered in ovulation induction-IUI to IVF conversions. (Fertil Steril(R) 2010;93:605-8. (C)2010 by American Society for Reproductive Medicine.)

AB The E2A-HLF fusion transcription factor generated by t(17;19)(q22;p13) translocation is found in a small subset of pro-B cell acute lymphoblastic leukemias (ALLs) and promotes leukemogenesis by substituting for the antiapoptotic function of cytokines. Here we show that t(17;19)(+) ALL cells express Survivin at high levels and that a dominant negative mutant of E2A-HLF suppresses Survivin expression. Forced expression of E2A-HLF in t(17;19)(-) leukemia cells up-regulated Survivin expression, suggesting that Survivin is a downstream target of E2A-HLF. Analysis using a counterflow centrifugal elutriator revealed that t(17;19)(+) ALL cells express Survivin throughout the cell cycle. Reporter assays revealed that E2A-HLF induces survivin expression at the transcriptional level likely through indirect down-regulation of a cell cycle-dependent cis element in the promoter region. Down-regulation of Survivin function by a dominant negative mutant of Survivin or reduction of Survivin expression induced massive apoptosis throughout the cell cycle in t(17;19)(+) cells mainly through caspase-independent pathways involving translocation of apoptosis-inducing factor (AIF) from mitochondria to the nucleus. AIF knockdown conferred resistance to apoptosis caused by down-regulation of Survivin function. These data indicated that reversal of AIF translocation by Survivin, which is induced by E2A-HLF throughout the cell cycle, is one of the key mechanisms in the protection of t(17;19)(+) leukemia cells from apoptosis.

AB Functional studies of human primary immune cells have been hampered by the lack of tools to silence gene functions. In this study, we report the application of a lentiviral RNA interference library in primary human T cells. Using a subgenomic short hair RNA library targeting similar to 1000 signaling genes, we identified novel genes that control the levels of IL-10 produced. IL-10 is a potent anti-inflammatory cytokine secreted by several cell types, including T regulatory type 1 cells, a subset of T regulatory cells that exert their suppressive activity through IL-10 secretion. FLT3, a known hematopoeitic growth factor, was found to be a negative regulator of IL-10 levels in activated T cells. This was based on several observations. First, FLT3 and its ligand (FL) were both induced by T cell activation. Second, silencing of FLT3 led to increased IL-10 levels, whereas addition of FL suppressed IL-10 secretion and increased FLT3 surface levels. Third, engagement of CD46, a known inducer of T regulatory type 1 cells, upregulated surface FLT3, and secreted FL, which then inhibited IL-10 production by T cells. Hence, FL and FLT3 form a novel regulatory feedback loop that limits IL-10 production in T cells. Our results identified FLT3 as a new regulator of T cell function and offer a strategy to genetically dissect specific pathways in T cells. The Journal of Immunology, 2010, 184: 685-693.

AB Vertebrates vary in resistance and resilience to infectious diseases, and the mechanisms that regulate the trade-off between these often opposing protective processes are not well understood. Variability in the sensitivity of species to the induction of damaging inflammation in response to equivalent pathogen loads (resilience) complicates the use of animal models that reflect human disease. We found that induction of proinflammatory cytokines from macrophages in response to inflammatory stimuli in vitro is regulated by proteins in the sera of species in inverse proportion to their in vivo resilience to lethal doses of bacterial lipopolysaccharide over a range of 10,000-fold. This finding suggests that proteins in serum rather than intrinsic cellular differences may play a role in regulating variations in resilience to microbe-associated molecular patterns between species. The involvement of circulating proteins as key molecules raises hope that the process might be manipulated to create better animal models and potentially new drug targets.

AB Human immunodeficiency virus type 1 (HIV-1) persists in a latent reservoir of infected resting memory CD4 cells in patients receiving antiretroviral therapy. We assessed whether multitarget therapy with enfuvirtide, 2 reverse-transcriptase inhibitors, and a ritonavir-boosted protease inhibitor leads to decay of this reservoir. Nineteen treatment-naive patients initiated this regimen; 9 experienced virologic suppression and continued enfuvirtide-containing therapy for at least 48 weeks. In enfuvirtide-treated patients with virological suppression, there was no decay of the latent reservoir (95% confidence interval for half-life, 11 months to infinity). The stability of the latent reservoir despite intensive therapy suggests that new strategies are needed to eradicate HIV-1 from this reservoir. (ClinicalTrials.gov identifier: NCT00051831.)

TI Interactions between Lipids and Human Anti-HIV Antibody 4E10 Can Be

AB Human 4E10 is one of the broadest-specificity, HIV-1-neutralizing monoclonal antibodies known, recognizing a membrane-proximal linear epitope on gp41. The lipid cross-reactivity of 4E10 has been alternately suggested either to contribute to the apparent rarity of 4E10-like antibody responses in HIV infections, through elimination by B-cell tolerance mechanisms to self-antigens, or to contribute to neutralization potency by virus-specific membrane binding outside of the membrane-proximal external region (MPER). To investigate how 4E10 interacts with membrane and protein components, and whether such interactions contribute to neutralization mechanisms, we introduced two mutations into 4E10 Fv constructs, Trp to Ala at position 100 in the heavy chain [W(H100)A] and Gly to Glu at position 50 in the light chain [G(L50)E], selected to disrupt potential lipid interactions via different mechanisms. Wild-type and mutant Fvs all bound with the same affinity to peptides and monomeric and trimeric gp140s, but the affinities for gp140s were uniformly 10-fold weaker than to peptides. 4E10 Fv binding responses to liposomes in the presence or absence of MPER peptides were weak in absolute terms, consistent with prior observations, and both mutations attenuated interactions even further, as predicted. The W(H100) A mutation reduced neutralization efficiency against four HIV-1 isolates, but the G(L50) E mutation increased potency across the same panel. Electron paramagnetic resonance experiments showed that the W(H100) A mutation, but not the G(L50) E mutation, reduced the ability of 4E10 to extract MPER peptides from membranes. These results show that 4E10 nonspecific membrane binding is separable from neutralization, which is achieved through specific peptide/ lipid orientation changes.

AB Activation of estrogen receptor alpha (ER alpha)results in both induction and repression of gene transcription; while mechanistic details of estrogen induction are well described, details of repression remain largely unknown. We characterized several ER alpha-repressed targets and examined in detail the mechanism for estrogen repression of Reprimo (RPRM), a cell cycle inhibitor. Estrogen repression of RPRM is rapid and robust and requires a tripartite interaction between ER alpha, histone deacetylase 7 (HDAC7), and FoxA1. HDAC7 is the critical HDAC needed for repression of RPRM; it can bind to ER alpha and represses ER alpha's transcriptional activity-this repression does not require HDAC7's deacetylase activity. We further show that the chromatin pioneer factor FoxA1, well known for its role in estrogen induction of genes, is recruited to the RPRM promoter, is necessary for repression of RPRM, and interacts with HDAC7. Like other FoxA1 recruitment sites, the RPRM promoter is characterized by H3K4me1/me2. Estrogen treatment causes decreases in H3K4me1/me2 and release of RNA polymerase II (Pol II) from the RPRM proximal promoter. Overall, these data implicate a novel role for HDAC7 and FoxA1 in estrogen repression of RPRM, a mechanism which could potentially be generalized to many more estrogen-repressed genes and hence be important in both normal physiology and pathological processes.

AB Angiotensin II (Ang II) and vascular endothelial growth factor (VEGF) are important mediators of kidney injury in diabetes. VEGF expression is increased in proximal tubules of mice with type 1 diabetes. In mouse proximal tubular epithelial cells (MCT) cultured with 30 mM glucose (HG) for 24 h, VEGF expression is increased at the protein and the mRNA level, suggesting a transcriptional mechanism. HG stimulation of VEGF synthesis is prevented by captopril, an inhibitor of angiotensin-converting enzyme, and, by losartan, a specific antagonist of angiotensin type 1 receptor (AT1), suggesting that VEGF synthesis is mediated by Ang II. Synthesis of angiotensinogen (AGT), a precursor of angiotensin II, is increased in MCTs cultured in HG. Although synthesis of renin and ACE is not affected by HG, their activity, is increased in the conditioned medium. Concentrations of Ang I and Ang II are also increased in conditioned medium from HG-treated MCTs and captopril prevents increased Ang II, but not Ang 1, synthesis. Finally, AT1 is activated in MCTs treated with HG, and its activation is prevented by captopril and losartan. The ERK pathway is activated by HG within minutes of stimulation and lasting for up to 24 h. The initial phase of ERK activation is due to HG itself and leads to AGT upregulation and the sustained phase is mediated for the most part by Ang II-activated AT1 receptor and leads to increased VEGF synthesis.
These data show that: (1) HG increases AGT synthesis and activation of renin and ACE by MCTs, leading to local production of Ang I and Ang II. (2) Ang II activates endogenous AT1 and stimulates synthesis of VEGF. (3) HG activation of ERK starts within minutes and lasts for up to 24h. Early ERK activation is involved in AGT upregulation and sustained ERK activation, mediated via AT1, is responsible for VEGF synthesis.
In conclusion, our study shows that MCTs express an endogenous renin-angiotensin system that is activated by high glucose to stimulate the synthesis of VEGF, through activation of the ERK pathway. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

AB The impact of genetic and environmental factors on human brain structure is of great importance for understanding normative cognitive and brain aging as well as neuropsychiatric disorders. However, most studies of genetic and environmental influences oil human brain structure have either focused on global measures or have had samples that were too small for reliable estimates. Using the classical twin design, we assessed genetic, shared environmental, and individual-specific environmental influences on individual differences in the size of 96 brain regions of interest (ROIs). Participants were 474 middle-aged male twins (202 pairs; 70 unpaired) in the Vietnam Era Twin Study of Aging (VETSA). They were 51-59 years old, and were similar to U.S. men in their age range in terms of sociodemographic and health characteristics. We measured thickness of cortical ROIs and volume of other ROIs. On average, genetic influences accounted for approximately 70% of the variance in the volume of global, subcortical, and ventricular ROIs and approximately 45% of the variance in the thickness of cortical ROIs. There was greater variability in the heritability of cortical ROIs (0.00-0.75) as compared with subcortical and ventricular ROIs (0.48-0.85). The results did not indicate lateralized heritability differences or greater genetic influences oil the size of regions underlying higher cognitive functions. The findings provide key information for imaging genetic Studies and other studies of brain phenotypes and endophenotypes. Longitudinal analysis will be needed to determine whether the degree of genetic and environmental influences changes for different ROIs from midlife to later life. (C) 2009 Elsevier Inc.

AB Examination of the three-dimensional axonal pathways in the developing brain is key to understanding the formation of cerebral connectivity. By tracing fiber pathways throughout the entire brain, diffusion tractography provides information that cannot be achieved by conventional anatomical MR imaging or histology. However, standard diffusion tractography (based on diffusion tensor imaging, or DTI) tends to terminate in brain areas with low water diffusivity, indexed by low diffusion fractional anisotropy (FA), which can be Caused by crossing fibers as well as fibers with less myelin. For this reason, DTI tractography is not effective for delineating the Structural changes that occur in the developing brain, where the process of myelination is incomplete, and where crossing fibers exist in greater numbers than in the adult brain. Unlike DTI, diffusion spectrum imaging (DSI) can define multiple directions of water diffusivity; as such, diffusion tractography based on DSI provides marked flexibility for delineation of fiber tracts in areas where the fiber architecture is complex and multidirectional, even in areas of low FA. In this study, we showed that FA values were lower in the white matter of newborn (postnatal day 0; P0) cat brains than in the white matter of infant (P35) and juvenile (P100) cat brains. These results correlated well with histological myelin stains of the white matter: the newborn kitten brain has much less myelin than that found in cat brains at later stages of development. Using DSI tractography, we successfully identified structural changes in thalamo-cortical and cortico-cortical association tracts in cat brains from one stage of development to another. in newborns, the main body of the thalamo-cortical tract was smooth, and fibers branching from it were almost straight, while the main body became more complex and branching fibers became Curved reflecting gyrification in the older cats. Cortico-cortical tracts in the temporal lobe were smooth in newborns, and they formed a sharper angle in the later stages of development. The cingulum bundle and superior longitudinal fasciculus became more visible with time. Within the first month after birth, structural changes occurred in these tracts that coincided with the formation of the gyri. These results show that DSI tractography has the potential for mapping morphological changes in low FA areas associated with growth and development. The technique may also be applicable to the study of other forms of brain plasticity, including future Studies in vivo. (C) 2009 Elsevier Inc. All rights reserved.

AB We casually observe many interactions that do not really concern us. Yet sometimes we need to be able to rapidly appraise whether an interaction between two people represents a real threat for one of them Father than an innocent tease. Using functional magnetic resonance imaging, we investigated whether small differences in the body language of two interacting people are picked up by the brain even if observers are performing an unrelated task. Fourteen participants were scanned while watching 3-s movies (192 trials and 96 scrambles) showing a male person either threatening or teasing a female one. In one task condition, observers categorized the interaction as threatening or teasing, and in the other, they monitored randomly appearing dots and categorized the color. Our results clearly show that right amygdala responds more to threatening than to teasing situations irrespective of the observers' task. When observers' attention is not explicitly directed to the situation, this heightened amygdala activation goes together with increased activity in body sensitive regions in fusiform gyrus, extrastriate body area-human motion complex and superior temporal sulcus and is associated with a better behavioral performance of the participants during threatening situations. In addition, regions involved in action observation (inferior frontal gyrus, temporoparietal junction, and inferior parietal lobe) and preparation (premotor, putamen) show increased activation for threat videos. Also regions involved in processing moral violations (temporoparietal junction, hypothalamus) reacted selectively to the threatening interactions. Taken together, our results show which brain regions react selectively to witnessing a threatening interaction even if the situation is not attended because the observers perform an unrelated task.

AB Different items in long-term knowledge are stored in the neocortex as partially overlapping representations that can be altered slightly with usage. This encoding scheme affords well-documented benefits, but potential costs have not been well explored. Here we use functional magnetic resonance imaging (fMRI), neurocomputational modeling, and electrophysiological measures to show that strengthening some visual object representations not only enhances the subsequent ability to identify those (repeated) objects-an effect long known as repetition priming-but also impairs the ability to identify other (non-repeated) objects-a new effect labeled antipriming. As a result, the non-repeated objects elicit increased neural activity likely for the purpose of reestablishing their previously weakened representations. These results suggest a novel reevaluation of the ubiquitously observed repetition effect on neural activity, and they indicate that maintenance relearning may be a crucial aspect of preserving overlapping neural representations of visual objects in long-term memory.

AB Background: In the context of a randomized controlled trial (RCT) on HIV testing in the emergency department (ED) setting, we evaluated preferences for survey modality and data quality arising from each modality.
Methods: Enrolled participants were offered the choice of answering a survey via audio computer assisted self-interview (ACASI) or pen and paper self-administered questionnaire (SAQ). We evaluated factors influencing choice of survey modality. We defined unusable data for a particular survey domain as answering fewer than 75% of the questions in the domain. We then compared ACASI and SAQ with respect to unusable data for domains that address sensitive topics.
Results: Of 758 enrolled ED patients, 218 (29%) chose ACASI, 343 chose SAQ (45%) and 197 (26%) opted not to complete either. Results of the log-binomial regression indicated that older (RR = 1.08 per decade) and less educated participants (RR = 1.25) were more likely to choose SAQ over ACASI. ACASI yielded substantially less unusable data than SAQ.
Conclusions: In the ED setting there may be a tradeoff between increased participation with SAQ versus better data quality with ACASI. Future studies of novel approaches to maximize the use of ACASI in the ED setting are needed.

AB A major obstacle for the discovery of psychoactive drugs is the inability to predict how small molecules will alter complex behaviors. We report the development and application of a high-throughput, quantitative screen for drugs that alter the behavior of larval zebrafish. We found that the multidimensional nature of observed phenotypes enabled the hierarchical clustering of molecules according to shared behaviors. Behavioral profiling revealed conserved functions of psychotropic molecules and predicted the mechanisms of action of poorly characterized compounds. In addition, behavioral profiling implicated new factors such as ether-a-go-go-related gene ( ERG) potassium channels and immunomodulators in the control of rest and locomotor activity. These results demonstrate the power of high-throughput behavioral profiling in zebrafish to discover and characterize psychotropic drugs and to dissect the pharmacology of complex behaviors.

AB Small scale miners use mercury to extract gold from ore in many countries. An environmental and health assessment was performed in Indonesia in two regions, Galangan in Central Kalimantan and Talawaan in Northern Sulawesi. The environmental assessment showed severe mercury contamination of the sediments, and increased mercury levels in local fish. For the health investigation 281 volunteers were recruited and examined by a standardized questionnaire, a neurological examination and neuro-psychological tests. A medical score was used consisting of significant factors of mercury intoxication. Mercury exposed workers showed typical symptoms of mercury intoxication, such as movement 'disorders (ataxia, tremor, dyschadochokinesia, etc.). Blood, urine and hair samples were taken from any participant and analyzed for mercury. The mercury concentration in the biomonitors was high, partly extreme high in the working population, increased in the population living in the same habitat and low in the control group. By a standard protocol which includes a combination of threshold values of mercury in the biomonitors and a medical sum score the diagnosis of chronic mercury intoxication was made for highly burdened workers (amalgam smelters) in 55% in Sulawesi and in 62% in Kalimantan. Less exposed mineral processors and the general population in the mining areas were also intoxicated to a high percentage. (C) 2009 Elsevier B.V. All rights reserved.

AB In 2003 UNIDO (United Nations Industrial Development Organization) conducted an environmental and health assessment in a small-scale mining area in Tanzania. BGS (British Geological Survey) per-formed the environmental assessment. The Institute of Forensic Medicine - University of Munich performed the health assessment. The results of the medical, neurological and neuro-psychological examination of 180 participants from the affected area of Rwamagasa and 31 controls were analyzed. Urine. blood and hair samples were analyzed to detect the level of mercury body burden. Mercury concentrations in the bio-monitors urine, blood and hair were statistically significantly higher in the exposed population from Rwamagasa compared to the control group from Katoro. Only amalgam burners showed mercury levels above the toxicological threshold limits. A speciation of mercury in hair indicated that mainly elemental mercury vapor contributed to the high body burden of the artisanal miners. 104 amalgam-burners, the most exposed population group, were examined. 25 of these workers were found to be intoxicated. Small-scale mining is a serious health hazard for amalgam burners. Reduction of the exposure is essential to prevent further damage. (C) 2009 Elsevier B.V. All rights reserved.

AB Objectives. Mixed hematopoietic chimerism is associated with islet allograft tolerance and may reverse auto immunity, We developed low intensity regimens for the induction of mixed chimerism and examined the effects on autoimmunity in prediabetic nonobese diabetic (NOD) mice.
Research Design and Methods. NOD mice received various combinations of total body irradiation, anti-CD154, anti-CD8 alpha, anti-CD4, and anti-Thy1.2 monoclonal antibodies, with or without transplantation of C57BL/6 bone marrow cells and were followed up for development of diabetes, chimerism, and donor skin graft survival. Autoimmunity was assessed by histologic examination of salivary glands and pancreata.
Results. Although conditioning alone prevented or delayed the onset of diabetes, stable mixed chimerism was required for the reversal of isletitis. Mixed chimerism and skin graft tolerance were achieved in NOD mice receiving anti-CD154 with bone marrow transplantation as the means of tolerizing peripheral CD4(+) T cells to alloantigens. However, isletitis was not reversed in allotolerant mixed chimeras prepared with this regimen.
Conclusions. Partial depletion of peripheral autoreactive NOD CD4(+) T cells is needed to achieve full reversal of isletitis by mixed chimerism induction from a protective donor strain, but it is not required for induction of specific tolerance to donor alloantigens. Thus, the requirements for tolerizing alloreactive and autoreactive NOD CD4 cells are distinct.

AB Background. Cerebrospinal fluid (CSF) analysis is often deferred in patients with cryptococcal disease, particularly in the absence of neurologic manifestations. We sought to determine whether a subset of solid organ transplant (SOT) recipients with high likelihood of central nervous system (CNS) disease could be identified in whom CSF analysis must be performed.
Methods. Patients comprised a multicenter cohort of SOT recipients with cryptococcosis.
Results. Of 129 (88%) of 146 SOT recipients with cryptococcosis who underwent CSF analysis, 80 (62%) had CNS disease. In the overall study population, abnormal mental status, time to onset of cryptococcosis more than 24 months posttransplantation (late-onset disease), serum cryptococcal antigen titer more than 1:64, and fungemia were independently associated with an increased risk of CNS disease. Of patients with abnormal mental status, 95% had CNS cryptococcosis. When only patients with normal mental status were considered, three predictors (serum antigen titer >1:64, fungemia, and late-onset disease) independently identified patients with CNS cryptococcosis; the risk of CNS disease was 14% if none, 39% if one, and 94% if two of the aforementioned predictors existed (chi(2) for trend P<0.001).
Conclusions. CSF analysis should be strongly considered in SOT recipients with cryptococcosis who have late-onset disease, fungemia, or serum cryptococcal antigen titer more than 1:64 even in the presence of normal mental status.

AB Previously published guidelines for the diagnosis and management of primary immune thrombocytopenia (ITP) require updating largely due to the introduction of new classes of therapeutic agents, and a greater understanding of the disease pathophysiology. However, treatment-related decisions still remain principally dependent on clinical expertise or patient preference rather than high-quality clinical trial evidence. This consensus document aims to report on new data and provide consensus-based recommendations relating to diagnosis and treatment of ITP in adults, in children, and during pregnancy. The inclusion of summary tables within this document, supported by information tables in the online appendices, is intended to aid in clinical decision making. (Blood. 2010; 115:168-186)

AB Background: Problem-based Learning (PBL) has been suggested as a key educational method of knowledge acquisition to improve medical education. We sought to evaluate the differences in medical school education between graduates from PBL-based and conventional curricula and to what extent these curricula fit job requirements.
Methods: Graduates from all German medical schools who graduated between 1996 and 2002 were eligible for this study. Graduates self-assessed nine competencies as required at their day-to-day work and as taught in medical school on a 6-point Likert scale. Results were compared between graduates from a PBL-based curriculum (University Witten/Herdecke) and conventional curricula.
Results: Three schools were excluded because of low response rates. Baseline demographics between graduates of the PBL-based curriculum (n = 101, 49% female) and the conventional curricula (n = 4720, 49% female) were similar. No major differences were observed regarding job requirements with priorities for "Independent learning/working" and "Practical medical skills". All competencies were rated to be better taught in PBL-based curriculum compared to the conventional curricula (all p < 0.001), except for "Medical knowledge" and "Research competence". Comparing competencies required at work and taught in medical school, PBL was associated with benefits in "Interdisciplinary thinking" (Delta + 0.88), "Independent learning/working" (Delta + 0.57), "Psycho-social competence" (Delta + 0.56), "Teamwork" (Delta + 0.39) and "Problem-solving skills" (Delta + 0.36), whereas "Research competence" (Delta - 1.23) and "Business competence" (Delta - 1.44) in the PBL-based curriculum needed improvement.
Conclusion: Among medical graduates in Germany, PBL demonstrated benefits with regard to competencies which were highly required in the job of physicians. Research and business competence deserve closer attention in future curricular development.

TI Extensive proteomic screening identifies the obesity-related NYGGF4
protein as a novel LRP1-interactor, showing reduced expression in early

AB Background: The low-density lipoprotein receptor related protein 1 (LRP1) has been implicated in Alzheimer's disease (AD) but its signalling has not been fully evaluated. There is good evidence that the cytoplasmic domain of LRP1 is involved in protein-protein interactions, important in the cell biology of LRP1.
Results: We carried out three yeast two-hybrid screens to identify proteins that interact with the cytoplasmic domain of LRP1. The screens included both conventional screens as well as a novel, split-ubiquitin-based screen in which an LRP1 construct was expressed and screened as a transmembrane protein. The split-ubiquitin screen was validated in a screen using full-length amyloid protein precursor (APP), which successfully identified FE65 and FE65L2, as well as novel interactors (Rab3a, Napg, and ubiquitin b). Using both a conventional screen as well as the split-ubiquitin screen, we identified NYGGF4 as a novel LRP1 interactor. The interaction between LRP1 and NYGGF4 was validated using two-hybrid assays, coprecipitation and colocalization in mammalian cells. Mutation analysis demonstrated a specific interaction of NYGGF4 with an NPXY motif that required an intact tyrosine residue. Interestingly, while we confirmed that other LRP1 interactors we identified, including JIP1B and EB-1, were also able to bind to APP, NYGGF4 was unique in that it showed specific binding with LRP1. Expression of NYGGF4 decreased significantly in patients with AD as compared to age-matched controls, and showed decreasing expression with AD disease progression. Examination of Nyggf4 expression in mice with different alleles of the human APOE4 gene showed significant differences in Nyggf4 expression.
Conclusions: These results implicate NYGGF4 as a novel and specific interactor of LRP1. Decreased expression of LRP1 and NYGGF4 over disease, evident with the presence of even moderate numbers of neuritic plaques, suggests that LRP1-NYGGF4 is a system altered early in disease. Genetic and functional studies have implicated both LRP1 and NYGGF4 in obesity and cardiovascular disease and the physical association of these proteins may reflect a common mechanism. This is particularly interesting in light of the dual role of ApoE in both cardiovascular risk and AD. The results support further studies on the functional relationship between NYGGF4 and LRP1.

AB All cancers carry somatic mutations. A subset of these somatic alterations, termed driver mutations, confer selective growth advantage and are implicated in cancer development, whereas the remainder are passengers. Here we have sequenced the genomes of a malignant melanoma and a lymphoblastoid cell line from the same person, providing the first comprehensive catalogue of somatic mutations from an individual cancer. The catalogue provides remarkable insights into the forces that have shaped this cancer genome. The dominant mutational signature reflects DNA damage due to ultraviolet light exposure, a known risk factor for malignant melanoma, whereas the uneven distribution of mutations across the genome, with a lower prevalence in gene footprints, indicates that DNA repair has been preferentially deployed towards transcribed regions. The results illustrate the power of a cancer genome sequence to reveal traces of the DNA damage, repair, mutation and selection processes that were operative years before the cancer became symptomatic.

TI Protocol: a rapid and economical procedure for purification of plasmid

AB Research in plant molecular biology involves DNA purification on a daily basis. Although different commercial kits enable convenient extraction of high-quality DNA from E. coli cells, PCR and agarose gel samples as well as plant tissues, each kit is designed for a particular type of DNA extraction work, and the cost of purchasing these kits over a long run can be considerable. Furthermore, a simple method for the isolation of binary plasmid from Agrobacterium tumefaciens cells with satisfactory yield is lacking. Here we describe an easy protocol using homemade silicon dioxide matrix and seven simple solutions for DNA extraction from E. coli and A. tumefaciens cells, PCR and restriction digests, agarose gel slices, and plant tissues. Compared with the commercial kits, this protocol allows rapid DNA purification from diverse sources with comparable yield and purity at negligible cost. Following this protocol, we have demonstrated: (1) DNA fragments as small as a MYC-epitope tag coding sequence can be successfully recovered from an agarose gel slice; (2) Miniprep DNA from E. coli can be eluted with as little as 5 mu l water, leading to high DNA concentrations (> 1 mu g/mu l) for efficient biolistic bombardment of Arabidopsis seedlings, polyethylene glycol (PEG)-mediated Arabidopsis protoplast transfection and maize protoplast electroporation; (3) Binary plasmid DNA prepared from A. tumefaciens is suitable for verification by restriction analysis without the need for large scale propagation; (4) High-quality genomic DNA is readily isolated from several plant species including Arabidopsis, tobacco and maize. Thus, the silicon dioxide matrix-based DNA purification protocol offers an easy, efficient and economical way to extract DNA for various purposes in plant research.

AB Understanding sex differences in stress regulation has important implications for understanding basic physiological differences in the male and female brain and their impact on vulnerability to sex differences in chronic medical disorders associated with stress response circuitry. In this functional magnetic resonance imaging study, we demonstrated that significant sex differences in brain activity in stress response circuitry were dependent on women's menstrual cycle phase. Twelve healthy Caucasian premenopausal women were compared to a group of healthy men from the same population, based on age, ethnicity, education, and right handedness. Subjects were scanned using negative valence/high arousal versus neutral visual stimuli that we demonstrated activated stress response circuitry [amygdala, hypothalamus, hippocampus, brainstem, orbitofrontal cortex (OFC), medial prefrontal cortex (mPFC), and anterior cingulate gyrus (ACG)]. Women were scanned twice based on normal variation in menstrual cycle hormones [i. e., early follicular (EF) compared with late follicular-midcycle (LF/MC) menstrual phases]. Using SPM8b, there were few significant differences in blood oxygenation level-dependent (BOLD) signal changes in men compared to EF women, except ventromedial nucleus (VMN), lateral hypothalamic area (LHA), left amygdala, and ACG. In contrast, men exhibited significantly greater BOLD signal changes compared to LF/MC women on bilateral ACG and OFC, mPFC, LHA, VMN, hippocampus, and periaqueductal gray, with largest effect sizes in mPFC and OFC. Findings suggest that sex differences in stress response circuitry are hormonally regulated via the impact of subcortical brain activity on the cortical control of arousal, and demonstrate that females have been endowed with a natural hormonal capacity to regulate the stress response that differs from males.

AB Myeloperoxidase (MPO) is increasingly being recognized as an important factor in many inflammatory diseases, particularly cardiovascular and neurological diseases. MPO-specific imaging agents would thus be highly useful to diagnose early disease, monitor disease progression, and quantify treatment effects. This study reports in vitro and in vivo characterizations of the mechanism of interaction between MPO and paramagnetic enzyme substrates based on physical and biological measurements. We show that these agents are activated through a radical mechanism, which can combine to form oligomers and, in the presence of tyrosine-containing peptide, bind to proteins. We further identified two new imaging agents, which represent the near extremes in either oligomerization (mono-5HT-DTPA-Gd) or protein-binding in their activation mechanism (bis-o-dianisidine-DTPA-Gd). On the other hand, we found that the agent bis-5HT-DTPA-Gd utilizes both mechanisms when activated. These properties yield distinct in vivo pharmacokinetics profiles for each of these agents that may be exploited for different applications. Specificity studies show that only MPO, but not eosinophil peroxidase, can highly activate these agents, and that MPO activity as low as 0.005 U/mg of tissue can be detected. Gd kinetic lability and cytotoxicity studies further confirm stability of the Gd ion and low toxicity for the 5HT-based agents, suggesting that these agents are suitable for translational in vivo studies.

RECEPTORS; RESTING STATE; TORPEDO; MECHANISM
AB The nicotinic acetylcholine receptor (nAChR) is a member of the important Cys loop ligand-gated ion channel superfamily that modulates neuronal excitability. After they respond to their agonists, their actions are terminated either by removal of ligand or by fast and slow desensitization, processes that play ail important role in modulating the duration of conducting states and hence of integrated neuronal behavior. We monitored structural changes Occurring during fast and slow desensitization in the transmembrane domain of the Torpedo nAChR using time-resolved photolabeling with the hydrophobic probe 3-(trifluoromethyl)-3-(m-iodophenyl)diazirine (TID). After channel opening, TID photolabels a residue oil the delta-subunit's M2-M3 loop and a cluster of four residues on delta M1 and delta M2, defining all open state pocket [Arevalo, E., et al. (2005) J. Biol. Chem. 280, 13631-13640]. We now find that photolabeling of this pocket persists during the transition to the fact desensitized state, the extent of photoincorporation decreasing only with the transition to the slow desensitized state. In contrast, the extent of photoincorporation in the channel lumen at the conserved 9'-leucines oil the second transmembrane helix (M2-9') decreased successively during the resting to open and open to fast desensitized state transitions, implying that the local conformation is different in each state, a Conclusion consistent with the hypothesis that there are separate gates for channel opening and desensitization. Thus, although during Cast desensitization there is a conformation change in the channel lumen at the level of M2-9', there is none in the regions of the delta-subunit's M2-M3 loop and the interior of its M1-M4 helix bundle until slow desensitization occurs.

AB Objective To investigate whether angiotensin receptor blockers protect against Alzheimer's disease and dementia or reduce the progression of both diseases.
Design Prospective cohort analysis.
Setting Administrative database of the US Veteran Affairs, 2002-6.
Population 819 491 predominantly male participants (98%) aged 65 or more with cardiovascular disease.
Main outcome measures Time to incident Alzheimer's disease or dementia in three cohorts (angiotensin receptor blockers, lisinopril, and other cardiovascular drugs, the "cardiovascular comparator") over a four year period (fiscal years 2003-6) using Cox proportional hazard models with adjustments for age, diabetes, stroke, and cardiovascular disease. Disease progression was the time to admission to a nursing home or death among participants with pre-existing Alzheimer's disease or dementia.
Results Hazard rates for incident dementia in the angiotensin receptor blocker group were 0.76 (95% confidence interval 0.69 to 0.84) compared with the cardiovascular comparator and 0.81 (0.73 to 0.90) compared with the lisinopril group. Compared with the cardiovascular comparator, angiotensin receptor blockers in patients with pre-existing Alzheimer's disease were associated with a significantly lower risk of admission to a nursing home (0.51, 0.36 to 0.72) and death (0.83, 0.71 to 0.97). Angiotensin receptor blockers exhibited a dose-response as well as additive effects in combination with angiotensin converting enzyme inhibitors. This combination compared with angiotensin converting enzyme inhibitors alone was associated with a reduced risk of incident dementia (0.54, 0.51 to 0.57) and admission to a nursing home (0.33, 0.22 to 0.49). Minor differences were shown in mean systolic and diastolic blood pressures between the groups. Similar results were observed for Alzheimer's disease.
Conclusions Angiotensin receptor blockers are associated with a significant reduction in the incidence and progression of Alzheimer's disease and dementia compared with angiotensin converting enzyme inhibitors or other cardiovascular drugs in a predominantly male population.

TI A score to predict early risk of recurrence after ischemic stroke

STROKE; ATTACK; SEVERITY; SURVIVAL; LEUKOARAIOSIS; PROGNOSIS; PATTERNS
AB Background: There is currently no instrument to stratify patients presenting with ischemic stroke according to early risk of recurrent stroke. We sought to develop a comprehensive prognostic score to predict 90-day risk of recurrent stroke.
Methods: We analyzed data on 1,458 consecutive ischemic stroke patients using a Cox regression model with time to recurrent stroke as the response and clinical and imaging features typically available to physician at admission as covariates. The 90-day risk of recurrent stroke was calculated by summing up the number of independent predictors weighted by their corresponding beta-coefficients. The resultant score was called recurrence risk estimator at 90 days or RRE-90 score (available at: http://www.nmr.mgh.harvard.edu/RRE-90/).
Results: Sixty recurrent strokes (54 had baseline imaging) occurred during the follow-up period. The risk adjusted for time to follow-up was 6.0%. Predictors of recurrence included admission etiologic stroke subtype, prior history of TIA/stroke, and topography, age, and distribution of brain infarcts. The RRE-90 score demonstrated adequate calibration and good discrimination (area under the ROC curve [AUC] = 0.70-0.80), which was maintained when applied to a separate cohort of 433 patients (AUC = 0.70-0.76). The model's performance was also maintained for predicting early (14-day) risk of recurrence (AUC = 0.80).
Conclusions: The RRE-90 is a Web-based, easy-to-use prognostic score that integrates clinical and imaging information available in the acute setting to quantify early risk of recurrent stroke. The RRE-90 demonstrates good predictive performance, suggesting that, if validated externally, it has promise for use in creating individualized patient management algorithms and improving clinical practice in acute stroke care.

AB Background: The U. S. Food and Drug Administration (FDA) recently linked antiepileptic drug (AED) exposure to suicide-related behaviors based on meta-analysis of randomized clinical trials. We examined the relationship between suicide-related behaviors and different AEDs in older veterans receiving new AED monotherapy from the Veterans Health Administration (VA), controlling for potential confounders.
Methods: VA and Medicare databases were used to identify veterans 66 years and older, who received a) care from the VA between 1999 and 2004, and b) an incident AED ( monotherapy) prescription. Previously validated ICD-9-CM codes were used to identify suicidal ideation or behavior (suicide-related behaviors cases), epilepsy, and other conditions previously associated with suicide-related behaviors. Each case was matched to controls based on prior history of suicide-related behaviors, year of AED prescription, and epilepsy status.
Results: The strongest predictor of suicide-related behaviors (N = 64; Controls N = 768) based on conditional logistic regression analysis was affective disorder ( depression, anxiety, or post-traumatic stress disorder (PTSD); Odds Ratio 4.42, 95% CI 2.30 to 8.49) diagnosed before AED treatment. Increased suicide-related behaviors were not associated with individual AEDs, including the most commonly prescribed AED in the US - phenytoin.
Conclusion: Our extensive diagnostic and treatment data demonstrated that the strongest predictor of suicide-related behaviors for older patients newly treated with AED monotherapy was a previous diagnosis of affective disorder. Additional, research using a larger sample is needed to clearly determine the risk of suicide-related behaviors among less commonly used AEDs.

HT22 neuronal cells were subjected to oxidative stress using the standard glutamate-induced glutathione depletion model. Primary rat astrocytes were exposed to H(2)O(2). Oxidative stress was induced in human brain endothelial cells with sodium nitroprusside (SNP). Edaravone significantly reduced oxidative cell death in both HT22 neuronal cells and primary rat astrocytes in a dose-dependent manner. SNP did not kill brain endothelial cells but instead reduced their production of brain-derived neurotrophic factor (BDNF). Edaravone significantly ameliorated this response. These data suggest that free radical scavengers are effective in all cell types of the neurovascular unit, and should still be considered as a potential therapeutic approach for stroke.

AB Objectives: Although near-normal conversational voices can be achieved with the phonosurgical management of early glottic cancer, there are still acoustic and aerodynamic deficits in vocal function that Must be better understood to help further optimize phonosurgical interventions. Stroboscopic assessment is inadequate for this purpose.
Methods: A newly developed color high-speed videoendoscopy (HSV) system that included time-synchronized recordings of the acoustic signal Was used to perform a detailed examination of voice production mechanisms in 14 Subjects. Digital image processing techniques were used to quantify glottal phonatory function and to delineate relationships between vocal fold vibratory properties and acoustic perturbation measures.
Results: The results for multiple measurements of vibratory asymmetry showed that 31% to 62% of subjects displayed higher-than-normal average values, whereas the mean values for glottal Closure duration (open quotient) and periodicity of vibration fell within normal limits. The average HSV-based measures did not correlate significantly with the acoustic perturbation Measures, but moderate correlations were exhibited between the acoustic measures and the SDs of the HSV-based parameters.
Conclusions: The use of simultaneous, time-synchronized HSV and acoustic recordings can provide new insights into postoperative voice production mechanisms that cannot be obtained with stroboscopic assessment.

AB Objectives: We sought to determine the feasibility of performing spontaneous and evoked intraoperative laryngeal electromyography (L-EMG) using nerve monitoring equipment and to compare recording electrode configurations and methods of recurrent laryngeal nerve (RLN) stimulation in dogs.
Methods: Four beagles underwent crush injury of the left RLN, and 2 beagles underwent left RLN transection. Serial spontaneous and evoked L-EMG was recorded with the NIM-Response nerve monitoring system under sedation. Transesophageal, percutaneous, and direct open RLN stimulation was performed. Recordings of spontaneous and evoked responses were made with endotracheal tube surface electrodes and bipolar vocal fold needle electrodes. The L-EMG procedures were repeated every 1 to 2 weeks after injury, and intersubject and intertrial differences were evaluated.
Results: Low-amplitude motor unit action potentials, polyphasic potentials, fasciculations, and fibrillations were detected in injured animals with bipolar needle recording electrodes with this system of spontaneous L-EMG. The surface recording electrodes did not detect pathologic waveforms. Percutaneous needle stimulation of the RLN is possible at Currents slightly higher than those used for direct stimulation. Consistent, discrete, transesophageal stimulation of the RLN could not be reliably performed. Recording evoked responses with needle electrodes generated sharper waveforms, facilitating calculation of latency and wave duration. Evoked L-EMG utilizing surface recording electrodes limited the intertrial and intersubject variability of evoked amplitude.
Conclusions: Typical patterns of nerve injury can be detected with this system of intraoperative L-EMG in a canine model. Quantitative measures of amplitude, latency, and wave duration in healthy and injured canine RLNs may be determined with this system.

BREAST-CANCER; BEVACIZUMAB
AB Purpose
There is an unmet need for biomarkers for identifying patients likely to benefit from anticancer treatments, selecting dose, and understanding mechanisms of resistance. Plasma vascular endothelial growth factor (VEGF) and soluble VEGF receptor 2 (sVEGFR-2) are known to be modulated by VEGF pathway inhibitors. It is unknown whether chemotherapy or VEGFR inhibitor/chemotherapy combinations induce changes in these or other cytokines and angiogenic factors (CAFs) and whether such changes could be markers of benefit.
Methods
Thirty-five plasma CAFs were analyzed using multiplexed bead arrays and enzyme-linked immunosorbent assays from 123 patients with non-small-cell lung cancer in a randomized phase II study who received vandetanib, a VEGFR and epidermal growth factor receptor inhibitor, monotherapy carboplatin and paclitaxel (CP), or the combination (VCP). Changes in CAFs at days 8, 22, and 43 from baseline were correlated with progression risk.
Results
VEGF increased and sVEGFR-2 decreased by day 43 in the vandetanib arm, whereas a distinct pattern was observed in the CP and VCP arms, with significant decreases in interleukin (IL) -12, IL-1 receptor antagonist, and matrix metalloproteinase 9 (MMP-9) and increased macrophage chemoattractant protein 1. In each treatment arm, changes in different markers were associated with progression risk. For example, increases in IL-8 with VCP, MMP-9 with CP, and VEGF with vandetanib monotherapy were associated with increased progression risk, and increase in intercellular adhesion molecule 1 with vandetanib was associated with decreased risk.
Conclusion
Vandetanib and chemotherapy treatment led to distinct patterns of CAF changes; the combination resembled chemotherapy alone. Changes in specific CAFs correlated with clinical outcome, but markers differed for each treatment arm. CAF profiling may provide insights into the biologic effects of treatment and identify drug-specific markers of activity and clinical benefit.

AB Purpose
During the last 25 years, National Cancer Institute (NCI) cooperative trial groups have extended trial networks from academic centers to include certain community and Veterans Health Administration (VHA) centers. We compared trial patients' attributes and outcomes by these enrollment settings.
Patients and Methods
Studying 2,708 patients on one of 10 cooperative group, randomized lung trials at 272 institutions, we compared patient attributes by enrollment setting (ie, academic, community, and VHA affiliates). We used adjusted Cox regression to evaluate for survival differences by setting.
Results
Main member institutions enrolled 44% of patients; community affiliates enrolled 44%; and VHAs enrolled 12%. Patient attributes (ie, case-mix) of age, ethnicity, sex, and performance status varied by enrollment setting. After analysis was adjusted for patient case-mix, no mortality differences by enrollment setting were noted.
Conclusion
Although trial patients with primarily advanced-stage lung cancer from nonacademic centers were older and had worse performance statuses than those from academic centers, survival did not differ by enrollment setting after analysis accounted for patient heterogeneity. An answer for whether long-term outcomes for patients at community and VHA centers affiliated with cooperative trial groups are equivalent to those at academic centers when care is delivered through NCI trials requires additional research among patients with longer survival horizons.

TI Paradoxes in Advance Care Planning: The Complex Relationship of Oncology
Patients, Their Physicians, and Advance Medical Directives
SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID OF-LIFE CARE; CANCER-PATIENTS; END; COMMUNICATION; DISCUSSIONS;
PREFERENCES; DEATH; ASSOCIATIONS; HEALTH; ILL
AB Purpose
Many seriously ill patients with cancer do not discuss prognosis or advance directives (ADs), which may lead to inappropriate and/or unwanted aggressive care at the end of life. Ten years ago, patients with cancer said they would not like to discuss ADs with their oncologist but would be willing to discuss them with an admitting physician. We assessed whether this point of view still held.
Patients and Methods
Semi-structured interviews were conducted with 75 consecutively admitted patients with cancer in the cancer inpatient service.
Results
Of those enrolled, 41% (31 of 75) had an AD. Nearly all (87%, 65 of 75) thought it acceptable to discuss ADs with the admitting physician with whom they had no prior relationship, and 95% (62 of 65) thought that discussing AD issues was very or somewhat important. Only 7% (5 of 75) had discussed ADs with their oncologist, and only 23% (16 of 70) would like to discuss ADs with their oncologist. When specifically asked which physician they would choose, 48% (36 of 75) of patients would prefer their oncologist, and 35% (26 of 75) would prefer their primary care physician.
Conclusion
Fewer than half of seriously ill patients with cancer admitted to an oncology service have an AD. Only 23% (16 of 70) would like to discuss their ADs with their oncologist but nearly all supported a policy of discussing ADs with their admitting physician. However, fully 48% (36 of 75) actually preferred to discuss advance directives with their oncologist if AD discussion was necessary. We must educate patients on why communicating their ADs is beneficial and train primary care physicians, house staff, hospitalists, and oncologists to initiate these difficult discussions.

Cancer: A Randomized Controlled Trial
SO JOURNAL OF CLINICAL ONCOLOGY

DT Article
ID ADVANCE DIRECTIVES; DECISION-MAKING; MEDICAL-CARE; COMMUNICATION;
PREFERENCES; SUPPORT; DEATH; PHYSICIANS; DEMENTIA
AB Purpose
To determine whether the use of a goals-of-care video to supplement a verbal description can improve end-of-life decision making for patients with cancer.
Methods
Fifty participants with malignant glioma were randomly assigned to either a verbal narrative of goals-of-care options at the end of life (control), or a video after the same verbal narrative (intervention) in this randomized controlled trial. The video depicts three levels of medical care: life-prolonging care (cardiopulmonary resuscitation [CPR], ventilation), basic care (hospitalization, no CPR), and comfort care (symptom relief). The primary study outcome was participants' preferences for end-of-life care. The secondary outcome was participants' uncertainty regarding decision making (score range, 3 to 15; higher score indicating less uncertainty). Participants' comfort level with the video was also measured.
Results
Fifty participants were randomly assigned to either the verbal narrative (n = 27) or video (n = 23). After the verbal description, 25.9% of participants preferred life-prolonging care, 51.9% basic care, and 22.2% comfort care. In the video arm, no participants preferred life-prolonging care, 4.4% preferred basic care, 91.3% preferred comfort care, and 4.4% were uncertain (P < .0001). The mean uncertainty score was higher in the video group than in the verbal group (13.7 v 11.5, respectively; P < .002). In the intervention arm, 82.6% of participants reported being very comfortable watching the video.
Conclusion
Compared with participants who only heard a verbal description, participants who viewed a goals-of-care video were more likely to prefer comfort care and avoid CPR, and were more certain of their end-of-life decision making. Participants reported feeling comfortable watching the video.

TI Clinical Definition of Acquired Resistance to Epidermal Growth Factor
Receptor Tyrosine Kinase Inhibitors in Non-Small-Cell Lung Cancer

AB Ten percent of North American patients with non-small-cell lung cancer have tumors with somatic mutations in the gene for the epidermal growth factor receptor (EGFR). Approximately 70% of patients whose lung cancers harbor somatic mutations in exons encoding the tyrosine kinase domain of EGFR experience significant tumor regressions when treated with the EGFR tyrosine kinase inhibitors (TKIs) gefitinib or erlotinib. However, the overwhelming majority of these patients inevitably acquire resistance to either drug. Currently, the clinical definition of such secondary or acquired resistance is not clear. We propose the following criteria be used to define more precisely acquired resistance to EGFR TKIs. All patients should have the following criteria: previous treatment with a single-agent EGFR TKI (eg, gefitinib or erlotinib); either or both of the following: a tumor that harbors an EGFR mutation known to be associated with drug sensitivity or objective clinical benefit from treatment with an EGFR TKI; systemic progression of disease (Response Evaluation Criteria in Solid Tumors [RECIST] or WHO) while on continuous treatment with gefitinib or erlotinib within the last 30 days; and no intervening systemic therapy between cessation of gefitinib or erlotinib and initiation of new therapy. The relatively simple definition proposed here will lead to a more uniform approach to investigating the problem of acquired resistance to EGFR TKIs in this unique patient population. These guidelines should minimize reporting of false-positive and false-negative activity in these clinical trials and would facilitate the identification of agents that truly overcome acquired resistance to gefitinib and erlotinib.

AB To recapitulate the stochastic nature of human cancer development, we have devised a strategy for generating mouse tumor models that involves stepwise genetic manipulation of embryonic stem (ES) cells and chimera generation. Tumors in the chimeric animals develop from engineered cells in the context of normal tissue. Adenocarcinomas arising in an allelic series of lung cancer models containing HER2 (also known as ERBB2), KRAS or EGFR oncogenes exhibit features of advanced malignancies. Treatment of EGFR(L858R) and KRAS(G12V) chimeric models with an EGFR inhibitor resulted in near complete tumor regression and no response to the treatment, respectively, accurately reflecting previous clinical observations. Transcriptome and immunohistochemical analyses reveal that PI3K pathway activation is unique to ERBB family tumors whereas KRAS-driven tumors show activation of the JNK/SAP pathway, suggesting points of therapeutic intervention for this difficult-to-treat tumor category.

AB Nanoparticles (NPs) of synthetic hydroxyapatite (Hap) and natural bone mineral (NBM) are rendered magnetic by treatment with iron ions using a wet-chemical process. The magnetic NPs (mNPs), which are about 300 nm in 1 diameter, display superparamagnetic properties in a superconducting quantum interference device, with a saturation magnetization of about 30 emu g(-1). X-ray diffraction and transmission electron microscopy reveal that the magnetic properties of the NPs are the result of the hetero-epitaxial 1 growth of magnetite on the Hap and NBM crystallites. The mNPs display a high binding affinity for plasmid DNA in contrast to magnetite NPs which do not bind the plasmid well. The mHap and mNBM NPs result in substantial increases in the transfection of rat marrow-derived mesenchymal stem cells with the gene for glial cell line-derived neurotrophic factor (GDNF), with magnetofection compared to transfection in the absence of a magnet. The : amount of GDNF recovered in the medium approaches therapeutic levels despite the small amount of plasmid delivered by the NPs.

AB We report a large Chinese family with X-linked postlingual nonsyndromic hearing impairment in which the critical linkage interval spans a genetic distance of 5.41 cM and a physical distance of 15.1 Mb that overlaps the DFN2 locus. Mutation screening of the PRPS1 gene in this family and in the three previously reported DFN2 families identified four different missense mutations in PRPS1. These Mutations result in a loss of phosphoribosyl pyrophosphate (PRPP) synthetase I activity, as was shown in silico by structural analysis and was shown in vitro by enzymatic activity assays in erythrocytes and fibroblasts from patients. By ill Situ hybridization, we demonstrate expression of Prps1 in murine vestibular and cochlea hair cells, with Continuous expression in hair cells and postnatal expression in the spiral ganglion. Being the second identified gene associated with X-linked nonsyndromic deafness, PRPS1 will be a good candidate gene for genetic testing for X-linked nonsyndromic hearing loss.

AB We report that eight heterozygous missense mutations in TUBB3, encoding the neuron-specific beta-tubulin isotype III, result in a spectrum of human nervous system disorders that we now call the TUBB3 syndromes. Each mutation causes the ocular motility disorder CFEOM3, whereas some also result in intellectual and behavioral impairments, facial paralysis, and/or later-onset axonal sensorimotor polyneuropathy. Neuroimaging reveals a spectrum of abnormalities including hypoplasia of oculomotor nerves and dysgenesis of the corpus callosum, anterior commissure, and corticospinal tracts. A knock-in disease mouse model reveals axon guidance defects without evidence of cortical cell migration abnormalities. We show that the disease-associated mutations can impair tubulin heterodimer formation in vitro, although folded mutant heterodimers can still polymerize into microtubules. Modeling each mutation in yeast tubulin demonstrates that all alter dynamic instability whereas a subset disrupts the interaction of microtubules with kinesin motors. These findings demonstrate that normal TUBB3 is required for axon guidance and maintenance in mammals.

AB Thyrotoxic hypokalemic periodic paralysis (TPP) is characterized by acute attacks of weakness, hypokalemia, and thyrotoxicosis of various etiologies. These transient attacks resemble those of patients with familial hypokalemic periodic paralysis (hypoKPP) and resolve with treatment of the underlying hyperthyroidism. Because of the phenotypic similarity of these conditions, we hypothesized that TPP might also be a channelopathy. While sequencing candidate genes, we identified a previously unreported gene (not present in human sequence databases) that encodes an inwardly rectifying potassium (Kir) channel, Kir2.6. This channel, nearly identical to Kir2.2, is expressed in skeletal muscle and is transcriptionally regulated by thyroid hormone. Expression of Kir2.6 in mammalian cells revealed normal Kir currents in whole-cell and single-channel recordings. Kir2.6 mutations were present in up to 33% of the unrelated TPP patients in our collection. Some of these mutations clearly alter a variety of Kir2.6 properties, all altering muscle membrane excitability leading to paralysis.

AB Polycomb group (PcG) proteins are essential for accurate axial body patterning during embryonic development. PcG-mediated repression is conserved in metazoans and is targeted in Drosophila by Polycomb response elements (PREs). However, targeting sequences in humans have not been described. While analyzing chromatin architecture in the context of human embryonic stem cell (hESC) differentiation, we discovered a 1.8kb region between HOXD11 and HOXD12(D11.12) that is associated with PcG proteins, becomes nuclease hypersensitive, and then shows alteration in nuclease sensitivity as hESCs differentiate. The D11.12 element repressed luciferase expression from a reporter construct and full repression required a highly conserved region and YY1 binding sites. Furthermore, repression was dependent on the PcG proteins BMI1 and EED and a YY1-interacting partner, RYBP. We conclude that D11.12 is a Polycomb-dependent regulatory region with similarities to Drosophila PREs, indicating conservation in the mechanisms that target PcG function in mammals and flies.

AB Cardiac fibroblasts are emerging as key components of normal cardiac function, as well as the response to stressors and injury. These most numerous cells of the heart interact with myocytes via paracrine mechanisms, alterations in extracellular matrix homeostasis, and direct cell-cell interactions. It is possible that they are a contributor to the inability of adult myocytes to proliferate and may influence cardiac progenitor biology. Furthering our understanding of how cardiac fibroblasts and myocytes interact may provide an avenue to novel treatments for heart failure prevention. This review discusses the most recent concepts in cardiac fibroblast-myocyte communication and areas of potential future research. (Circ Res. 2010;106:47-57.)

AB MutM, a bacterial DNA glycosylase, protects genome integrity by catalyzing glycosidic bond cleavage of 8-oxoguanine (oxoG) lesions, thereby initiating base excision DNA repair. The process of searching for and locating oxoG lesions is especially challenging, because of the close structural resemblance of oxoG to its million-fold more abundant progenitor, G. Extrusion of the target nucleobase from the DNA double helix to an extrahelical position is an essential step in lesion recognition and catalysis by MutM. Although the interactions between the extruded oxoG and the active site of MutM have been well characterized, little is known in structural detail regarding the interrogation of extruded normal DNA bases by MutM. Here we report the capture and structural elucidation of a complex in which MutM is attempting to present an undamaged G to its active site. The structure of this MutM-extrahelical G complex provides insights into the mechanism MutM employs to discriminate against extrahelical normal DNA bases and into the base extrusion process in general.

AB Oncolytic adenoviruses represent a promising therapeutic medicine for human cancer therapy, but successful translation into human clinical trials requires careful evaluation of their viral characteristics. While the function of adenovirus proteins has been analyzed in detail, the dynamics of adenovirus infection remain largely unknown due to technological constraints that prevent adequate tracking of adenovirus particles after infection. Fluorescence labeling of adenoviral particles is one new strategy designed to directly analyze the dynamic processes of viral infection in virus-host cell interactions. We hypothesized that the double labeling of an adenovirus with fluorescent proteins would allow us to properly analyze intracellular viruses and the fate of viral proteins in a live analysis of an adenovirus as compared to single labeling. Thus, we generated a fluorescently labeled adenovirus with both a red fluorescent minor capsid protein IX (pIX) [pIX monomeric red fluorescent protein 1 (mLRFP1)] and a green fluorescent minor core protein V (pV) [pV enhanced green fluorescent protein (EGFP)], resulting in Ad5-IX-mRFP1-E3-V-EGFP. The fluorescent signals for pIX-n-LRFP1 and pV-EGFP were detected within 10 min in living cells. However, a growth curve analysis of Ad5-IX-mRFP1-E3-V-EGFP showed an approximately 150-fold reduced production of the viral progeny at 48 h postinfection as compared to adenovirus type 5. Interestingly, pIX-mRFP1 and pV-EGFP were initially localized in the cytoplasm and nucleolus, respectively, at 18 h postinfection. These proteins were observed in the nucleus during the late stage of infection, and relocalization of the proteins was observed in an adenoviral-replication-dependent manner These results indicate that simultaneous detection of adenoviruses using dual-fluorescent proteins is Suitable for real-time analysis, including identification of infected cells and monitoring of viral spread, which will be required for a complete evaluation of oncolytic adenoviruses.

AB Cocaine-induced alterations in gene expression cause changes in neuronal morphology and behavior that may underlie cocaine addiction. In mice, we identified an essential role for histone 3 lysine 9 (H3K9) dimethylation and the lysine dimethyltransferase G9a in cocaine-induced structural and behavioral plasticity. Repeated cocaine administration reduced global levels of H3K9 dimethylation in the nucleus accumbens. This reduction in histone methylation was mediated through the repression of G9a in this brain region, which was regulated by the cocaine-induced transcription factor Delta FosB. Using conditional mutagenesis and viral-mediated gene transfer, we found that G9a down-regulation increased the dendritic spine plasticity of nucleus accumbens neurons and enhanced the preference for cocaine, thereby establishing a crucial role for histone methylation in the long-term actions of cocaine.

AB BACKGROUND
Since the patient's skin is a major source of pathogens that cause surgical-site infection, optimization of preoperative skin antisepsis may decrease postoperative infections. We hypothesized that preoperative skin cleansing with chlorhexidine-alcohol is more protective against infection than is povidone-iodine.
METHODS
We randomly assigned adults undergoing clean-contaminated surgery in six hospitals to preoperative skin preparation with either chlorhexidine-alcohol scrub or povidone-iodine scrub and paint. The primary outcome was any surgical-site infection within 30 days after surgery. Secondary outcomes included individual types of surgical-site infections.
RESULTS
A total of 849 subjects (409 in the chlorhexidine-alcohol group and 440 in the povidone-iodine group) qualified for the intention-to-treat analysis. The overall rate of surgical-site infection was significantly lower in the chlorhexidine-alcohol group than in the povidone-iodine group (9.5% vs. 16.1%; P = 0.004; relative risk, 0.59; 95% confidence interval, 0.41 to 0.85). Chlorhexidine-alcohol was significantly more protective than povidone-iodine against both superficial incisional infections (4.2% vs. 8.6%, P = 0.008) and deep incisional infections (1% vs. 3%, P = 0.05) but not against organ-space infections (4.4% vs. 4.5%). Similar results were observed in the per-protocol analysis of the 813 patients who remained in the study during the 30-day follow-up period. Adverse events were similar in the two study groups.
CONCLUSIONS
Preoperative cleansing of the patient's skin with chlorhexidine-alcohol is superior to cleansing with povidone-iodine for preventing surgical-site infection after clean-contaminated surgery. (ClinicalTrials.gov number, NCT00290290.)

TI The number of beams in IMRT-theoretical investigations and implications

SO PHYSICS IN MEDICINE AND BIOLOGY

DT Article
ID MODULATED ARC; CONFORMAL RADIOTHERAPY; MULTILEAF COLLIMATOR; ROTATION
THERAPY; X-RAYS; IMPLEMENTATION
AB The first purpose of this paper is to shed some new light on the old question of selecting the number of beams in intensity-modulated radiation therapy (IMRT). The second purpose is to illuminate the related issue of discrete static beam angles versus rotational techniques, which has recently re-surfaced due to the advancement of volumetric modulated arc therapy (VMAT). A specific objective is to find analytical expressions that allow one to address the points raised above. To make the problem mathematically tractable, it is assumed that the depth dose is flat and that the lateral dose profile can be approximated by polynomials, specifically Chebyshev polynomials of the first kind, of finite degree. The application of methods known from image reconstruction then allows one to answer the first question above as follows: the required number of beams is determined by the maximum degree of the polynomials used in the approximation of the beam profiles, which is a measure of the dose variability. There is nothing to be gained by using more beams. In realistic cases, in which the variability of the lateral dose profile is restricted in several ways, the required number of beams is of the order of 10-20. The consequence of delivering the beams with a 'leaf sweep' technique during continuous rotation of the gantry, as in VMAT, is also derived in an analytical form. The main effect is that the beams fan out, but the effect near the axis of rotation is small. This result can serve as a theoretical justification of VMAT. Overall the analytical derivations in this paper, albeit based on strong simplifications, provide new insights into, and a deeper understanding of, the beam angle problem in IMRT. The decomposition of the beam profiles into well-behaved and easily deliverable smooth functions, such as Chebyshev polynomials, could be of general interest in IMRT treatment planning.

AB Background: Mathematical models of tuberculosis (TB) transmission have been used to characterize disease dynamics, investigate the potential effects of public health interventions, and prioritize control measures. While previous work has addressed the mathematical description of TB natural history, the impact of demography on the behaviour of TB models has not been assessed.
Methods: A simple model of TB transmission, with alternative assumptions about survivorship, is used to explore the effect of age structure on the prevalence of infection, disease, basic reproductive ratio and the projected impact of control interventions. We focus our analytic arguments on the differences between constant and exponentially distributed lifespans and use an individual-based model to investigate the range of behaviour arising from realistic distributions of survivorship.
Results: The choice of age structure and natural (non-disease related) mortality strongly affects steady-state dynamics, parameter estimation and predictions about the effectiveness of control interventions. Since most individuals infected with TB develop an asymptomatic latent infection and never progress to active disease, we find that assuming a constant mortality rate results in a larger reproductive ratio and an overestimation of the effort required for disease control in comparison to using more realistic age-specific mortality rates.
Conclusions: Demographic modelling assumptions should be considered in the interpretation of models of chronic infectious diseases such as TB. For simple models, we find that assuming constant lifetimes, rather than exponential lifetimes, produces dynamics more representative of models with realistic age structure.

AB Diffusion MRI (dMRI) is widely used to measure microstructural features of brain white matter, but commonly used dMRI measures have limited capacity to resolve the orientation structure of complex fiber architectures. While several promising new approaches have been proposed, direct quantitative validation of these methods against relevant histological architectures remains missing. In this study, we quantitatively compare neuronal fiber orientation distributions (FODs) derived from ex vivo dMRI data against histological measurements of rat brain myeloarchitecture using manual recordings of individual myelin stained fiber orientations. We show that accurate FOD estimates can be obtained from dMRI data, even in regions with complex architectures of crossing fibers with an intrinsic orientation error of approximately 5-6 degrees in these regions. The reported findings have implications for both clinical and research studies based on dMRI FOD measures, and provide an important biological benchmark for improved FOD reconstruction and fiber tracking methods.

AB Dynamic regulation of insulin signaling and metabolic gene expression is critical to nutrient homeostasis; dysregulation of these pathways is widely implicated in insulin resistance and other disease states. Though the metabolic effects of insulin are well established, the components linking insulin signal transduction to a metabolic response are not as well understood. Here, we show that Cdc2-like kinase 2 (Clk2) is an insulin-regulated suppressor of hepatic gluconeogenesis and glucose output. Clk2 protein levels and kinase activity are induced as part of the hepatic refeeding response by the insulin/Akt pathway. Clk2 directly phosphorylates the SR domain on PGC-1 alpha, resulting in repression of gluconeogenic gene expression and hepatic glucose output. In addition, Clk2 is downregulated in db/db mice, and reintroduction of Clk2 largely corrects glycemia. Thus, we have identified a role for and regulation of the Clk2 kinase as a component of hepatic insulin signaling and glucose metabolism.

AB Previous studies indicate that androgen deprivation therapy for prostate cancer is associated with diabetes and cardiovascular disease among older men. We evaluated the relationship between androgen deprivation therapy and incident diabetes and cardiovascular disease in men of all ages with prostate cancer.
We conducted an observational study of 37 443 population-based men who were diagnosed with local or regional prostate cancer in the Veterans Healthcare Administration from January 1, 2001, through December 31, 2004, with follow-up through December 31, 2005. Cox proportional hazards models were used to assess whether androgen deprivation therapy with gonadotropin-releasing hormone (GnRH) agonists, oral antiandrogens, the combination of the two (ie, combined androgen blockade), or orchiectomy was associated with diabetes, coronary heart disease, myocardial infarction, sudden cardiac death, or stroke, after adjustment for patient and tumor characteristics. All statistical tests were two-sided.
Overall, 14 597 (39%) of the 37 443 patients were treated with androgen deprivation therapy. Treatment with GnRH agonists was associated with statistically significantly increased risks of incident diabetes (for GnRH agonist therapy, 159.4 events per 1000 person-years vs 87.5 events for no androgen deprivation therapy, difference = 71.9, 95% confidence interval [CI] = 71.6 to 72.2; adjusted hazard ratio [aHR] = 1.28, 95% CI = 1.19 to 1.38), incident coronary heart disease (aHR = 1.19, 95% CI = 1.10 to 1.28), myocardial infarction (12.8 events per 1000 person-years for GnRH agonist therapy vs 7.3 for no androgen deprivation therapy, difference = 5.5, 95% CI = 5.4 to 5.6; aHR = 1.28, 95% CI = 1.08 to 1.52), sudden cardiac death (aHR = 1.35, 95% CI = 1.18 to 1.54), and stroke (aHR = 1.22, 95% CI = 1.10 to 1.36). Combined androgen blockade was statistically significantly associated with an increased risk of incident coronary heart disease (aHR = 1.27, 95% CI = 1.05 to 1.53), and orchiectomy was associated with coronary heart disease (aHR = 1.40, 95% CI = 1.04 to 1.87) and myocardial infarction (aHR = 2.11, 95% CI = 1.27 to 3.50). Oral antiandrogen monotherapy was not associated with any outcome studied.
Androgen deprivation therapy with GnRH agonists was associated with an increased risk of diabetes and cardiovascular disease.

AB Background-In patients with acute coronary syndromes and planned percutaneous coronary intervention, the Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition With Prasugrel-Thrombolysis in Myocardial Infarction 38 (TRITON-TIMI 38) demonstrated that treatment with prasugrel versus clopidogrel was associated with reduced rates of cardiovascular death, MI, or stroke and an increased risk of major bleeding. We evaluated the cost-effectiveness of prasugrel versus clopidogrel from the perspective of the US healthcare system by using data from TRITON-TIMI 38.
Methods and Results-Detailed resource use data were prospectively collected for all patients recruited from 8 countries (United States, Australia, Canada, Germany, Italy, Spain, United Kingdom, and France; n=3373 prasugrel, n=3332 clopidogrel). Hospitalization costs were estimated on the basis of diagnosis-related group and in-hospital complications. Cardiovascular medication costs were estimated by using net wholesale prices (clopidogrel =$4.62/d; prasugrel =$5.45/d). Life expectancy was estimated from in-trial cardiovascular and bleeding events with the use of statistical models of long-term survival from a similar population from the Saskatchewan Health Database. Over a median follow-up of 14.7 months, average total costs (including study drug) were $221 per patient lower with prasugrel (95% confidence interval, -759 to 299), largely because of a lower rate of rehospitalization involving percutaneous coronary intervention. Prasugrel was associated with life expectancy gains of 0.102 years (95% confidence interval, 0.030 to 0.180), primarily because of the decreased rate of nonfatal MI. Thus, compared with clopidogrel, prasugrel was an economically dominant treatment strategy. If a hypothetical generic cost for clopidogrel of $1/d is used, the incremental net cost with prasugrel was $996 per patient, yielding an incremental cost-effectiveness ratio of $9727 per life-year gained.
Conclusion-Among acute coronary syndrome patients with planned percutaneous coronary intervention, treatment with prasugrel versus clopidogrel for up to 15 months is an economically attractive treatment strategy.

AB Background-Pulmonary arterial hypertension is a progressive proliferative vasculopathy of the small pulmonary arteries that is characterized by a primary failure of the endothelial nitric oxide and prostacyclin vasodilator pathways, coupled with dysregulated cellular proliferation. We have recently discovered that the endogenous anion salt nitrite is converted to nitric oxide in the setting of physiological and pathological hypoxia. Considering the fact that nitric oxide exhibits vasoprotective properties, we examined the effects of nitrite on experimental pulmonary arterial hypertension.
Methods and Results-We exposed mice and rats with hypoxia or monocrotaline-induced pulmonary arterial hypertension to low doses of nebulized nitrite (1.5 mg/min) 1 or 3 times a week. This dose minimally increased plasma and lung nitrite levels yet completely prevented or reversed pulmonary arterial hypertension and pathological right ventricular hypertrophy and failure. In vitro and in vivo studies revealed that nitrite in the lung was metabolized directly to nitric oxide in a process significantly enhanced under hypoxia and found to be dependent on the enzymatic action of xanthine oxidoreductase. Additionally, physiological levels of nitrite inhibited hypoxia-induced proliferation of cultured pulmonary artery smooth muscle cells via the nitric oxide-dependent induction of the cyclin-dependent kinase inhibitor p21Waf1/Cip1. The therapeutic effect of nitrite on hypoxia-induced pulmonary hypertension was significantly reduced in the p21-knockout mouse; however, nitrite still reduced pressures and right ventricular pathological remodeling, indicating the existence of p21-independent effects as well.
Conclusion-These studies reveal a potent effect of inhaled nitrite that limits pathological pulmonary arterial hypertrophy and cellular proliferation in the setting of experimental pulmonary arterial hypertension. (Circulation. 2010; 121: 98-109.)

AB The question of whether dedicated progenitor cells exist in adult vertebrate pancreas remains controversial. Centroacinar cells and terminal duct (CA/TD) cells lie at the junction between peripheral acinar cells and the adjacent ductal epithelium, and are frequently included among cell types proposed as candidate pancreatic progenitors. However these cells have not previously been isolated in a manner that allows formal assessment of their progenitor capacities. We have found that a subset of adult CA/TD cells are characterized by high levels of ALDH1 enzymatic activity, related to high-level expression of both Aldh1a1 and Aldh1a7. This allows their isolation by FACS using a fluorogenic ALDH1 substrate. FACS-isolated CA/TD cells are relatively depleted of transcripts associated with differentiated pancreatic cell types. In contrast, they are markedly enriched for transcripts encoding Sca1, Sdf1, c-Met, Nestin, and Sox9, markers previously associated with progenitor populations in embryonic pancreas and other tissues. FACS-sorted CA/TD cells are uniquely able to form self-renewing "pancreatospheres" in suspension culture, even when plated at clonal density. These spheres display a capacity for spontaneous endocrine and exocrine differentiation, as well as glucose-responsive insulin secretion. In addition, when injected into cultured embryonic dorsal pancreatic buds, these adult cells display a unique capacity to contribute to both the embryonic endocrine and exocrine lineages. Finally, these cells demonstrate dramatic expansion in the setting of chronic epithelial injury. These findings suggest that CA/TD cells are indeed capable of progenitor function and may contribute to the maintenance of tissue homeostasis in adult mouse pancreas.

AB Lipodystrophy and obesity are opposites in terms of a deficiency versus excess of adipose tissue mass, yet these conditions are accompanied by similar metabolic consequences, including insulin resistance, dyslipidemia, hepatic steatosis, and increased risk for diabetes and atherosclerosis. Hepatic and myocellular steatosis likely contribute to metabolic dysregulation in both states. Inflammation and macrophage infiltration into adipose tissue also appear to participate in the pathogenesis of obesity-induced insulin resistance, but their contributions to lipodystrophy-induced insulin resistance have not been evaluated. We used aP2-nSREBP-1c transgenic (Tg) mice, an established model of lipodystrophy, to ask this question. Circulating cytokine elevations suggested systemic inflammation but even more dramatic was the number of infiltrating macrophages in all white and brown adipose tissue depots of the Tg mice; in contrast, there was no evidence of inflammatory infiltrates or responses in any other tissue including liver. Despite there being overt evidence of adipose tissue inflammation, antiinflammatory strategies including salicylate treatment and genetic suppression of myeloid NF-kappa B signaling that correct insulin resistance in obesity were ineffective in the lipodystrophic mice. We further showed that adipose tissue macrophages (ATMs) in lipodystrophy and obesity are very different in terms of activation state, gene expression patterns, and response to lipopolysaccharide. Although ATMs are even more abundant in lipodystrophy than in obesity, they have distinct phenotypes and likely roles in tissue remodeling, but do not appear to be involved in the pathogenesis of insulin resistance.

AB The prognosis for adults with precursor B-cell acute lymphoblastic leukemia (B-ALL) remains poor, in part from a lack of therapeutic targets. We identified the type I cytokine receptor subunit CRLF2 in a functional screen for B-ALL-derived mRNA transcripts that can substitute for IL3 signaling. We demonstrate that CRLF2 is over-expressed in approximately 15% of adult and high-risk pediatric BALL that lack MLL, TCF3, TEL, and BCR/ABL rearrangements, but not in B-ALL with these rearrangements or other lymphoid malignancies. CRLF2 overexpression can result from translocation with the IGH locus or intrachromosomal deletion and is associated with poor outcome. CRLF2 overexpressing B-ALLs share a transcriptional signature that significantly overlaps with a BCR/ABL signature, and is enriched for genes involved in cytokine receptor and JAK-STAT signaling. In a subset of cases, CRLF2 harbors a Phe232Cys gain-of-function mutation that promotes constitutive dimerization and cytokine independent growth. A mutually exclusive subset harbors activating mutations in JAK2. In fact, all 22 B-ALLs with mutant JAK2 that we analyzed overexpress CRLF2, distinguishing CRLF2 as the key scaffold for mutant JAK2 signaling in B-ALL. Expression of WT CRLF2 with mutant JAK2 also promotes cytokine independent growth that, unlike CRLF2 Phe232Cys or ligand-induced signaling by WT CRLF2, is accompanied by JAK2 phosphorylation. Finally, cells dependent on CRLF2 signaling are sensitive to small molecule inhibitors of either JAKs or protein kinase C family kinases. Together, these findings implicate CRLF2 as an important factor in B-ALL with diagnostic, prognostic, and therapeutic implications.

AB Free MEG and EEG data analysis software packages springing from academic research are now widely used in published work. These toolboxes and applications are typically developed by or in close contact with researchers addressing cognitive or clinical neuroscience questions. Thus they often contain the latest methodological developments from the research community. It is therefore vital to educate MEG researchers and make them aware of the new possibilities offered by these toolboxes. The aim of this paper is to illustrate the characteristics and advantages of the various toolboxes to users and developers alike. We present each toolbox with their key features and target audience.

AB Two-dimensional optic flow is an important cue to perceive 3D structure of objects. Recent neuroimaging studies suggest the involvement of both the ventral and the dorsal visual pathways in the perception of 3D structure from motion (3D-SFM), though the neural dynamics underlying the 3D-SEM is not fully understood. Here, we combine magnetoencephalography (MEG) and fMRI to detect the dynamic brain responses to 3D-SFM. We manipulated the coherence of randomly moving dots to create different levels of 3D perception and investigated the associated changes in brain activity. Results of the fMRI analysis were used to impose plausible constraints on the MEG inverse calculation to improve spatial resolution of the spatiotemporal activity estimates. Time-frequency analysis was also employed to elucidate spatiotemporal dynamic changes in the spontaneous brain activities.
MEG-fMRI combined analysis showed that the activities the posterior infero-temporal (pIT), parieto-occipital (PO), and intra-parietal (IP) regions were increased at different latencies during highly coherent motion conditions in which subjects perceived a robust 3D object. Results of the time-frequency analysis indicated the suppression of alpha- and beta-band activities in these regions which reflect the commitment of these areas in the perception of 3D-SFM. Current results suggest that the interactions between the dorsal and ventral visual subsystems are crucial for the perception of 3D object from 2D optic flow.

AB To investigate how, where and when moving auditory cues interact with the perception of object-motion during self-motion, we conducted psychophysical, MEG, and fMRI experiments in which the subjects viewed nine textured objects during simulated forward self-motion. On each trial, one object was randomly assigned its own looming motion within the scene. Subjects reported which of four labeled objects had independent motion within the scene in two conditions: (1) visual information only and (2) with additional moving-auditory cue.
In MEG, comparison of the two conditions showed: (i) MT activity is similar across conditions, (ii) late after the stimulus presentation there is additional activity in the auditory cue condition ventral to MT, (iii) with the auditory cue, the right auditory cortex (AC) shows early activity together with STS, (iv) these two activities have different time courses and the STS signals occur later in the epoch together with frontal activity in the right hemisphere, (v) for the visual-only condition activity in PPC (posterior parietal cortex) is stronger than in the auditory-cue condition. fMRI conducted for visual-only condition reveals activations in a network of parietal and frontal areas and in MT.
In addition, Dynamic Granger Causality analysis showed for auditory cues a strong connection of the AC with STP but not with MT suggesting binding of visual and auditory information at STP. Also, while in the visual-only condition PFC is connected with MT, in the auditory-cue condition PFC is con-nected to STP (superior temporal polysensory) area.
These results indicate that PFC allocates attention to the "object" as a whole, in STP to a moving visual-auditory object, and in MT to a moving visual object.

AB We propose a 3D segmentation algorithm to locate the esophagus in thoracic CT scans using a learning based approach. To ease the training data requirement and allow maximum inter-subject flexibility, we built a simple algorithm based on normalization to anatomical reference points to match a training set of thoracic CTs instead of a full statistical registration based on neighboring structures. We use spatial and appearance models to locate the centerline. We build a shape model by subtracting the centerline and applying PCA to the training data sets. The shape model includes a mean shape plus the weighted combination of modes. To locate the esophageal wall, we optimize a cost function including terms for appearance, shape model, smoothness constraints and air/contrast model using a 3D level set framework.

ID CAENORHABDITIS-ELEGANS
AB The roundworm Caenorhabditis elegans is an effective model system for biological processes such as immunity, behavior, and metabolism. Robotic sample preparation together with automated microscopy and image analysis has recently enabled high-throughput screening experiments using C. elegans. So far, such experiments have been limited to per-image measurements due to the tendency of the worms to cluster, which prevents extracting features from individual animals.
We present a novel approach for the extraction of individual C. elegans from clusters of worms in high-throughput microscopy images. The key ideas are the construction of a low-dimensional shape-descriptor space and the definition of a probability measure on it. Promising segmentation results are shown.

AB Exposure to medical radiation is an important healthcare concern. In this paper we present a variational formulation for image reconstruction from low-dose transmission X-ray CT as well as its application to real clinical data. Our projection domain reconstruction method is based on high-order total variation penalties. We apply the method to clinical neck data obtained from a current 64-channel MDCT helical scanner, where small features and large dynamic range variation are pervasive. The ability to generate high-quality images even at 75% dose reduction is demonstrated. In particular, our approach exhibits image SNR comparable to full-dose filtered backprojection images while avoiding the obvious stair case and blockiness artifacts typically encountered in such methods.

ID NONRIGID IMAGE REGISTRATION; OPTIMIZATION; MOTION
AB Recent advances in medical imaging technologies have made 4D image sequences available in clinical routine. As a consequence, image registration techniques are evolving from alignment of pairs of static volumetric images to spatiotemporal registration of dynamic (4D) images. Since the elastic image registration problem is ill-posed, additional prior information or constraints are usually required to regularize the problem. This work proposes to enforce local invertibility (diffeomorphism) of 4D deformations. A novel sufficient condition for local invertibility over continuous space and time is proposed and a practical regularization prior is designed from the theory. The method has been applied to an image registration (motion tracking) of a dynamic 4D CT image sequence. Results show that using proposed regularizer leads to deformations that are more plausible for respiratory motion than the standard approach without additional temporal regularization.

ID HEART-RATE-VARIABILITY; MEDITATION; MODEL
AB Respiratory sinus arrhythmia (RSA) is largely mediated by the autonomic nervous system through its modulating influence on the heartbeat. We propose an algorithm for quantifying instantaneous RSA as applied to heart beat interval and respiratory recordings under dynamic respiration conditions. The blood volume pressure derived heart beat series (pulse intervals, PI) are modeled as an inverse gaussian point process, with the instantaneous mean PI modeled as a bivariate regression incorporating both past PI and respiration values observed at the beats. A point process maximum likelihood algorithm is used to estimate the model parameters, and instantaneous RSA is estimated by a frequency domain transfer function approach. The model is statistically validated using Kolmogorov-Smirnov (KS) goodness-of-fit analysis, as well as independence tests. The algorithm is applied to subjects engaged in meditative practice, with distinctive dynamics in the respiration patterns elicited as a result. Experimental results confirm the ability of the algorithm to track important changes in cardiorespiratory interactions elicited during meditation, otherwise not evidenced in control resting states.

ID SLEEP; ACTIGRAPHY; BED
AB Disrupted sleep patterns are a significant problem in the elderly, leading to increased cognitive dysfunction and risk of nursing home placement. A cost-effective and unobtrusive way to remotely monitor changing sleep patterns over time would enable improved management of this important health problem. We have developed an algorithm to derive sleep parameters such as bed time, rise time, sleep latency, and nap time from passive infrared sensors distributed around the home. We evaluated this algorithm using 404 days of data collected in the homes of 8 elderly community-dwelling elders. Data from this algorithm were highly correlated to ground truth measures (bed mats) and were surprisingly robust to variability in sensor layout and sleep habits.

AB We present a preliminary quantitative study aimed at developing an optimal standard protocol for automatic classification of specific affective states as related to human-computer interactions. This goal is mainly achieved by comparing standard psychological test-reports to quantitative measures derived from simultaneous non-invasive acquisition of psychophysiological signals of interest, namely respiration, galvanic skin response, blood volume pulse, electrocardiogram and electroencephalogram. Forty-three healthy students were exposed to computer-mediated stimuli, while wearable non-invasive sensors were applied in order to collect the physiological data. The stimuli were designed to elicit three distinct affective states: relaxation, engagement and stress. In this work we report how our quantitative analysis has helped in redefining important aspects of the protocol, and we show preliminary findings related to the specific psychophysiological patterns correlating with the three target affective states. Results further suggest that some of the quantitative measures might be useful in characterizing specific affective states.

ID BAROREFLEX SENSITIVITY; GENERAL-ANESTHESIA; RATE-VARIABILITY; SEQUENCE
AB Modeling heartbeat variability remains a challenging signal-processing goal in the presence of highly non-stationary cardiovascular control dynamics. We propose a novel differential autoregressive modeling approach within a point process probability framework for analyzing R-R interval and blood pressure variations. We apply the proposed model to both synthetic and experimental heartbeat intervals observed in time-varying conditions. The model is found to be extremely effective in tracking non-stationary heartbeat dynamics, as evidenced by the excellent goodness-of-fit performance. Results further demonstrate the ability of the method to appropriately quantify the non-stationary evolution of baroreflex sensitivity in changing physiological and pharmacological conditions.

ID EEG
AB The electroencephalogram (EEG) is widely used in the investigation of neurological disorders. Continuous long-term EEG data offers the opportunity to assess patient health over long periods of time, and to discover previously unknown physiological phenomena. However, the sheer volume of information generated by long-term EEG monitoring also poses a serious challenge for both analysis and visualization.
Symbolization has been successful in addressing information overload in many disciplines. In this paper, we present different approaches to transform EEG signals into symbolic sequences. This discrete symbolic representation reduces the amount of EEG data by several orders of magnitude and makes the task of discovering and visualizing interesting activity more manageable. We describe alternate methodologies to symbolize EEG data from patients with epilepsy. When evaluated on long-term intracranial data from 10 patients, our symbolization produced results that were consistent with clinical labels of seizures (for 97% of the seizures and 68% of the seizure segments), and often produced finer-grained distinctions.

AB In numerous neuroscience studies, multichannel EEG data are often recorded over multiple trial periods under the same experimental condition. To date, little effort is aimed to learn spatial patterns from EEG data to account for trial-to-trial variability. In this paper, a hierarchical Bayesian framework is introduced to model inter-trial source variability while extracting common spatial patterns under multiple experimental conditions in a supervised manner. We also present a variational Bayesian algorithm for model inference, by which the number of sources can be determined effectively via automatic relevance determination (ARD). The efficacy of the proposed learning algorithm is validated with both synthetic and real EEG data. Using two brain-computer interface (BCI) motor imagery data sets we show the proposed algorithm consistently outperforms the common spatial patterns (CSP) algorithm while attaining comparable performance with a recently proposed discriminative approach.

DE Brain machine interfaces; recursive Bayesian filters; neural signal
processing; optimal control
AB Brain machine interfaces work by mapping the relevant neural activity to the intended movement known as 'decoding'. Here, we develop a recursive Bayesian decoder for goal-directed movements from neural observations, which exploits the optimal feedback control model of the sensorimotor system to build better prior state-space models. These controlled state models depend on the movement duration that is not known a priori. We thus consider a discretization of the task duration and develop a decoder consisting of a bank of parallel point-process filters, each combining the neural observation with the controlled state model of a discretization point. The final reconstruction is made by optimally combining these filter estimates. Using very coarse discretization and hence only a few parallel branches, our decoder reduces the root mean square (RMS) error in trajectory reconstruction in reaches made by a rhesus monkey by approximately 40%.

AB We develop a state space approach to multimodal integration of simultaneously recorded EEG and fMRI. The EEG is represented with a distributed current source model using realistic MRI-based forward models, whose temporal evolution is governed by a linear state space model. The fMRI signal is similarly modeled by a linear state space model describing the hemodynamic response to underlying EEG current activity. We explore the feasibility of high dimensional dynamic estimation of simultaneous EEG/fMRI using simulation studies of the alpha wave.

AB In poorly constrained extra-vascular environments such as hollow viscera, current catheter navigation techniques are restricted to simple paths and therefore limit a doctor's ability to position the catheter. This paper presents a new catheter positioning system that enables faster and more accurate catheter placement, with fewer scans. The proposed robotic catheter navigation system can execute curved paths and maintain any number of three-dimensional turns using tension stiffening guide-wires composed of a set of disposable friction-locking beads. An external, reusable control system is used to automate the movement of the catheter. This control system uses a custom-designed graphical kinematic analysis program that predicts contact forces, changes in conformation due to external forces, tip deflection and failure modes of the catheter as it advances.

ID SPATIAL-RESOLUTION; PET; SIMULATION
AB Positron range depends on the materials in which positron propagates and on positron emitter isotope. As positron range limits the spatial resolution of PET images, good quantitative estimates of it should be included in any realistic simulation of PET acquisitions. In this work we compare positron range estimates obtained with PeneloPET to previous available simulations and experimental data. PeneloPET was used to simulate the positron range of F-18, C-11, N-13, O-15, Ga-68 and Rb-82 in the following tissues: cortical bone, soft bone, skin, muscle, brain, water, adipose tissue and lung. The 3D and 1D annihilation Point Spread Functions (aPSF) were calculated for each isotope-material combination. We have studied with more detail the 3D aPSF (radial distributions) and the cumulative fraction of annihilation events. These aPSF distributions were also studied for non-uniform media. Results obtained were consistent with other results previously reported in the literature as well as with experimentally measured data.

AB The scatter fraction (SF) in PET data represents the fraction of coincidence events in which at least one of the two emitted photons have been scattered before being detected. It is usually estimated as the ratio of scattered events to total number of coincidences, when the number of random counts is negligible (less than 1% of true rates). SF provides a measurement of the relative sensitivity of the scanner to scattered radiation. It depends on object size, density and location inside the field of view, as well as on detector size, type of detector crystal and energy window. The performance evaluation guideline for small-animal PET NEMA (National Electrical Manufacturers Association) NU4-2008 proposes the estimation of the SF for three test phantoms made in proportion to the most widely used small animals in the laboratory: mouse, rat and monkey. The method estimates the different coincidence types in sinogram profiles from an off-centered line source inserted in these phantoms. We benchmark the procedure proposed by NEMA to estimate SF with F-18 and also with Ga-68, a radionuclide with lager positron range. Real data acquired with the ARGUS small-animal PET scanner (SEDECAL, Madrid, Spain) as well as simulations of the same scanner with peneloPET are used. The results show that, though SF should be practically the same with both F-18 and Ga-68 isotopes (and indeed our simulations indicate this) NEMA SF estimations with Ga-68 acquisitions are higher. This is due to the fact that Ga-68 positron range affects on the width of the line source profiles. Suggestions to modify the protocol to obtain similar SF estimations when using isotopes with larger positron range than F-18 are made.

AB Presently, an estimated 35 million people are living with HIV, 300 million with Hepatitis C (HCV), with thousands of human fatalities registered ever day due to these and similar infectious diseases. Efficient, reliable, inexpensive medical solutions are therefore needed to tackle these issues. Identification of HIV and HCV is however not easy. Being significantly smaller than cells and bacteria, these viruses escape the isolation capabilities of both macroscopic and microscopic (MEMS) medical instrumentation. Allowing access to sub-micron species such as viruses and cancer cells, integration of nanotechnologies in medical devices has the potential to revolutionize the field of biomedicine. In this work, we explore the potential of nanoporous, patterned forests of vertically-aligned carbon nanotubes (VACNTs) for bioparticle isolation, demonstrating their ability to access particles over several orders of magnitude in size, from viruses (similar to 40nm) to cells (similar to 10 mu m). Modifying the flow field inside microfluidic channels, CNT-enhanced biodevices result in a seven-fold increase in capture efficiency compared to a nonporous design, as well as the ability to simultaneously isolate multiple distinct biospecies both inside and on the outer surface of the VACNT features. Our technology represents a versatile, highly efficient approach to biological isolation, with applications ranging from point-of-care diagnostics to subsequent therapeutic modalities in both infectious diseases as well as cancer applications.

AB Studying interfacial stresses is an important step towards understanding load distributions in mechanical, biomedical, and industrial systems. This paper presents a capacitive sensor that is capable of simultaneously measuring compressive and shear stresses. The sensor consists of two electrode layers separated by a set of flexible and compressible polymer pillars. The sensor's response to compressive and shear stresses was tested and characterized up to 320 kPa and 70 kPa respectively. An algorithm to estimate the applied stresses based on sensor output was developed and validated. The applied compressive stresses were estimated with an accuracy of 95.04 % and shear stress with an accuracy of 89.45 %.

AB Calcium is an essential second messenger in plant signaling networks. Many environmental and developmental stimuli induce an increase in cytosolic calcium to trigger different physiological responses. The specificity of Ca2+ signaling is achieved by a combination of distinct calcium signatures that are generated by specific calcium channels, pumps and transporters, and diverse calcium sensors that differ by their expression pattern, sub-cellular localization, substrate specificities and calcium sensitivities. Calcium binding modifies the structural conformation or enzymatic activity of the calcium sensors, which subsequently regulate downstream targets. Calmodulin is the most important Ca2+ transducer in eukaryotes and regulates numerous proteins with diverse cellular functions, including protein kinases. Plants also possess specific multigene families of protein kinases that play crucial roles in mediating calcium signaling. The multiplicity and diversity of plant calcium sensors, as well as the interconnections between various signal transduction pathways, constitute a tightly regulated signaling network that induces specific stress responses to improve plant survival.

AB Purpose
To directly examine the relationship between commercial support of continuing medical education (CME) and perceived bias in the content of these activities.
Method
Cross-sectional study of 213 accredited live educational programs organized by a university provider of CME from 2005 to 2007. A standard question from course evaluations was used to determine the degree to which attendees believed commercial bias was present. Binomial regression models were used to determine the association between course features that may introduce commercial bias and the extent of perceived bias at those CME activities.
Results
Mean response rate for attendee evaluations was 56% (SD 15%). Commercial support covered 20%-49% of costs for 45 (21%) educational activities, and >= 50% of costs for 46 activities (22%). Few course participants perceived commercial bias, with a median of 97% (interquartile range 95%-99%) of respondents stating that the activity they attended was free of commercial bias. There was no association between extent of commercial support and the degree of perceived bias in CME activities. Similarly, perceived bias did not vary for 11 of 12 event characteristics evaluated as potential sources of commercial bias, or by score on a risk index designed to prospectively assess risk of commercial bias.
Conclusions
Rates of perceived bias were low for the vast majority of CME activities in the sample and did not differ by the degree of industry support or other event characteristics. Further study is needed to determine whether commercial influence persisted in more subtle forms that were difficult for participants to detect.

TI Detecting Epidermal Growth Factor Receptor Tumor Activity In Vivo During

AB Rationale and Objectives: Noninvasive molecular imaging of glioma tumor receptor activity was assessed with diagnostic in vivo fluorescence monitoring during targeted therapy. The study goals were to assess the range of use for treatment monitoring and stratification of tumor types using epidermal growth factor (EGF) receptor (EGFR) status with administration of fluorescently labeled EGF and determine its utility for tumor detection compared to magnetic resonance imaging (MRI).
Materials and Methods: EGFR+ and EGFR- glioma tumor lines (human glioma [U251-GFP] and rat gliosarcoma [9L-GFP], respectively) were used to assess these goals, having a 20-fold difference between their EGF uptakes.
Results: Treatment with cetuximab in the EGFR+ tumor-bearing animals led to decreased EGF tumor uptake, whereas for the EGFR-tumors, no change in fluorescence signal followed treatment. This diagnostic difference in EGFR expression could be used to stratify the tumor-bearing animals into groups of potential responders and nonresponders, and receiver-operating characteristic curve analysis revealed an area under the curve (AUC) of 0.92 in separating these tumors. The nonlocalized growth pattern of U251-GFP tumors resulted in detection difficulty on standard MRI, but high EGFR expression made them detectable by fluorescence imaging (AUC = 1.0). The EGFR+ U251-GFP tumor-bearing animals could be noninvasively stratified into treated and untreated groups on the basis of fluorescence intensity difference (P=.035, AUC=0.90).
Conclusions: EGFR expression was tracked in vivo with fluorescence and determined to be of use for the stratification of EGFR+ and EGFR- tumors, the detection of EGFR+ tumors, and monitoring of molecular therapy.

AB Cytokinesis is the last step in the cell cycle, where daughter cells finally separate. It is precisely regulated in both time and space to ensure that each daughter cell receives an equal share of DNA and other cellular materials. Chemical biology approaches have been used very successfully to study the mechanism of cytokinesis. In this review, we discuss the use of small molecule probes to perturb cytokinesis, as well as the role naturally occurring small molecule metabolites such as lipids play during cytokinesis.

ID RADICAL PROSTATECTOMY; RANDOMIZED-TRIAL; SCREENING TRIAL;
NATURAL-HISTORY; MORTALITY; ANTIGEN; LIFE
AB Screening for prostate cancer with prostate-specific antigen (PSA), a simple blood test, is complex, controversial, intellectually challenging and ethically concerning. Sweden has contributed actively to the knowledge base for PSA screening in the last couple of years and a more informed debate is now possible. I will in this article summarize what we currently know about PSA testing. I discuss the closely related issues of the natural history of early-stage disease and the risks and benefits of radical local treatment. I propose that the mortality reduction following PSA screening is probably modest, whilst substantial harms are well documented. Furthermore, there is growing evidence that the PSA test is profoundly limited for screening purposes. I therefore concur with the growing number of health and professional agencies - notably outside the US that advise against population screening with PSA. Through PSA screening the medical community has generated a pseudo-epidemic of over-diagnosed non-lethal prostate cancer. Molecular tools to distinguish innocent, over-diagnosed prostate cancer from lethal tumors that deserving curative treatment are necessary to improve screening test performance. To date, extensive attempts to identify molecular predictors of outcome have remained unsuccessful, and no ideal screening test is within sight.

AB Acupuncture, one of the most prevalent methodologies of Traditional Chinese Medicine (TCM), has been used in Asian countries for curing numerous diseases for thousands of years. However, the true mechanisms underlying the effectiveness of acupuncture are still under debating. The meridian model based on TCM has been used so far, for guiding the practice of acupuncture. In this model, acupuncture is believed to treat the diseased organ of the patient by balancing the Yin and Yang conditions that are regulated by an energy substance (Qi) flowing constantly through the whole meridian, a network connecting all the organs of the body. Therefore, in the acupuncture treatment, it is crucial to select special acupoint(s) along the meridian that links the diseased organs, as well as to modulate the Qi flowing in the meridian through the induction of the needling sensation (De-Qi). On the other hand, a neurobiological model established in the recent decades, has supported the notion that an important mechanism of acupuncture in curing diseases is mediated by the nervous system. Stimulation by needles at acupoints is considered to initiate acupuncture signals through the nerve fibers (e.g., A(beta) and A(delta)) innervated at the deep tissue near the acupoints. The acupuncture signal is transmitted through the central nervous system, which activates and integrates with the neurons located in broad areas, such as those in the cortex, limbic system, brainstem, spinal cord, which in turn, regulate other systems. The nerve-mediated model provides us a better explanation regarding the biological mechanisms of acupuncture signal transmission in the body which has been broadly documented by both in vivo and in vitro studies under controlled conditions. In this chapter, we will review in particular, the research concerning the influence of acupuncture-elicited signals in the nervous system and how the neural pathways mediate the therapeutic effects of acupuncture.

AB Substance use disorder (SUD) patients who become involved in 12-step mutual-help groups (MHGs), such as Alcoholics Anonymous, experience better outcomes and have reduced healthcare costs. In spite of this, many do not attend at all and other initial attendees drop out. Reasons for non-attendance and dropout have not been systematically studied, yet such knowledge could enhance the efficiency of twelve-step facilitation (TSF) efforts or help clinicians decide which patients might prefer non-12-step MHGs (e.g., SMART Recovery). This study developed and tested a measure of reasons for non-participation and dropout from 12-step MHGs. Items were generated and clustered into eight domains using a rational keying approach. Male veterans (N = 60; M age = 49; 41% African American) undergoing SUD treatment were asked to complete a brief assessment about prior MHG experiences. Psychometric analyses produced a 24-item measure containing seven internally consistent, face-valid, subscales. Co-morbid psychiatric issues and, to a lesser degree, spiritual concerns, were found to be particularly important dimensions relating to this phenomenon. The measure could serve as a useful screening tool for barriers to 12-step participation and subsequently focus TSF efforts or inform referral to non-12 step MHGs.70% luminal narrowing) as compared with 0% in controls.
Conclusion: Young, asymptomatic, HIV-infected men with long-standing HIV disease demonstrate an increased prevalence and degree of coronary atherosclerosis compared with non-HIV-infected patients. Both traditional and nontraditional risk factors contribute to atherosclerotic disease in HIV-infected patients. (C) 2010 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins

AB Objective: To evaluate rates of antiretroviral therapy (ART) initiation within 12 months of a new HIV diagnosis in Durban, South Africa. Design: Prospective observational cohort.
Methods: Adults (>= 18 years) were enrolled before HIV testing at two outpatient clinics into the South African Test, Identify and Link cohort. Both sites offer comprehensive HIV care. HIV test results, CD4 cell counts, dates of ART initiation and dates of death were collected from medical records and 12-month patient/family interviews were conducted. ART eligibility was defined as a CD4 cell count less than 200 cells/mu l within 90 days of HIV diagnosis. The primary endpoint was ART initiation within 12 months for ART-eligible subjects.
Results: From November 2006 to October 2008, 1474 newly diagnosed HIV-infected outpatients were enrolled, 1012 (691%) of whom underwent CD4 cell count testing within 90 days. The median CD4 cell count was 159 cells/mu l (interquartile range 65299). Of those who underwent CD4 cell count testing, 538 (53%) were ART-eligible. Only 210 (39%) eligible enrollees were known to have initiated ART within 12 months. Among ART-eligible subjects, there were 108 known deaths; 82% occurred before ART initiation or with unknown ART initiation status. Men rate ratio (RR) 1.3, 95% confidence interval (CI) 1.1-1.51 and subjects without an HIV-infected family member/friend (RR 1.3, 95% CI 1.1-1.7) were more likely not to start ART.
Conclusion: Less than half of ART-eligible subjects started ART within 12 months. Substantial attrition and mortality follow HIV diagnosis before ART initiation in Durban, South Africa. Major efforts directed towards earlier HIV diagnosis, effective linkage to care and timely ART initiation are urgently needed.

AB This analysis was designed to explore the frequency of problem drinking and its role in potentiating HIV risk among a community-recruited sample of Black men who have sex with men (MSM) in Massachusetts. Black MSM (n=197) recruited via modified respondent-driven sampling between January and July 2008 completed an interviewer-administered survey, including HIV sexual behavior, the Center for Epidemiologic Studies Depression Scale (CES-D), and the CAGE alcohol screener. Bivariate and multivariable logistic regression procedures examined the association of behavioral HIV-risk factors and other psychosocial variables with problematic alcohol use (CAGE score 3 or 4). Overall, 29% of the sample was found to abuse alcohol. In a multivariable model adjusting for demographic and behavioral variables, factors associated with increased odds of problem drinking were: (1) depressive symptoms (CES-D 16+ ); (2) one or more episodes of serodiscordant unprotected anal sex during last sexual encounter with a casual male partner; and (3) one or more episodes of unprotected anal or vaginal sex with a female partner in the past 12 months. Black MSM who engaged in HIV risk behaviors may be more likely to have concurrent problematic alcohol use. HIV prevention interventions with Black MSM may benefit from incorporating screening and/or treatment for alcohol problems, as well as screening for co-morbid depressive symptoms.

TI "We fear the police, and the police fear us": structural and individual
barriers and facilitators to HIV medication adherence among injection

ID ANTIRETROVIRAL THERAPY HAART; ACCESS; METHADONE
AB Ukraine has one of the most severe HIV/AIDS epidemics in Europe, with an estimated 1.63% of the population living with HIV/AIDS in 2007. Injection drug use (IDU) remains the predominant mode of transmission in Kiev - the capital and largest city. Prior reports suggest that the HIV infection rate among IDUs in Kiev reaches 33%, and many have poor and inequitable access to highly active antiretroviral therapy (HAART). Among those with access to HAART, little is understood about barriers and facilitators to HAART medication adherence. In May 2009, two semi-structured focus groups were conducted with HIV-infected IDUs seeking treatment at the City AIDS Center, Kiev. The goal was to use this information to adapt and tailor, to Ukrainian culture, an evidence-based intervention for improving adherence to HAART. All 16 participants attributed HIV infection to IDU. Their average age was 31.6 (SD=7.0), average time with HIV 5.7 years (SD=4.0), average time on HAART 2.5 years (SD=1.7), average time as IDU 14.6 years (SD=6.8), and 88% were on opioid substitution therapy. The most salient themes related to adherence barriers included: (1) harassment and discrimination by police; (2) opioid dependence; (3) complexity of drug regimen; (4) side effects; (5) forgetting; (6) co-occurring mental health problems; and (7) HIV stigma. Facilitators of adherence included: (1) cues for pill taking; (2) support and reminders from family, significant other, and friends; (3) opioid substitution therapy; and (4) wanting improved health. Additional factors explored included: (1) knowledge about HAART; (2) storage of medications; and (3) IDU and sexual risk behaviors. Findings highlighted structural and individual barriers to adherence. At the structural level, police discrimination and harassment was reported to be a major barrier to adherence to opioid substitution therapy and HAART. Privacy and stigma were barriers at the individual level. Recommendations for adherence interventions included education, training, and identification cards to show police that medication was for treatment of HIV, not for abuse; and involving family members and other systems of support for HIV treatment.

TI HIVBrainSeqDB: a database of annotated HIV envelope sequences from brain

DT Article

TISSUES; REPLICATION; TROPISM; BLOOD; MODEL; ENV
AB Background: The population of HIV replicating within a host consists of independently evolving and interacting sub-populations that can be genetically distinct within anatomical compartments. HIV replicating within the brain causes neurocognitive disorders in up to 20-30% of infected individuals and is a viral sanctuary site for the development of drug resistance. The primary determinant of HIV neurotropism is macrophage tropism, which is primarily determined by the viral envelope (env) gene. However, studies of genetic aspects of HIV replicating in the brain are hindered because existing repositories of HIV sequences are not focused on neurotropic virus nor annotated with neurocognitive and neuropathological status. To address this need, we constructed the HIV Brain Sequence Database.
Results: The HIV Brain Sequence Database is a public database of HIV envelope sequences, directly sequenced from brain and other tissues from the same patients. Sequences are annotated with clinical data including viral load, CD4 count, antiretroviral status, neurocognitive impairment, and neuropathological diagnosis, all curated from the original publication. Tissue source is coded using an anatomical ontology, the Foundational Model of Anatomy, to capture the maximum level of detail available, while maintaining ontological relationships between tissues and their subparts. 44 tissue types are represented within the database, grouped into 4 categories: (i) brain, brainstem, and spinal cord; (ii) meninges, choroid plexus, and CSF; (iii) blood and lymphoid; and (iv) other (bone marrow, colon, lung, liver, etc). Patient coding is correlated across studies, allowing sequences from the same patient to be grouped to increase statistical power. Using Cytoscape, we visualized relationships between studies, patients and sequences, illustrating interconnections between studies and the varying depth of sequencing, patient number, and tissue representation across studies. Currently, the database contains 2517 envelope sequences from 90 patients, obtained from 22 published studies. 1272 sequences are from brain; the remaining 1245 are from blood, lymph node, spleen, bone marrow, colon, lung and other non-brain tissues. The database interface utilizes a faceted interface, allowing real-time combination of multiple search parameters to assemble a meta-dataset, which can be downloaded for further analysis.
Conclusions: This online resource, which is publicly available at http://www.HIVBrainSeqDB.org, will greatly facilitate analysis of the genetic aspects of HIV macrophage tropism, HIV compartmentalization and evolution within the brain and other tissue reservoirs, and the relationship of these findings to HIV-associated neurological disorders and other clinical consequences of HIV infection.

AB Background: Few data are available to guide programmatic solutions to the overlapping problems of undernutrition and HIV infection. We evaluated the impact of food assistance on patient outcomes in a comprehensive HIV program in central Haiti in a prospective observational cohort study.
Methods: Adults with HIV infection were eligible for monthly food rations if they had any one of: tuberculosis, body mass index (BMI) <18.5kg/m(2), CD4 cell count <350/mm(3) (in the prior 3 months) or severe socio-economic conditions. A total of 600 individuals (300 eligible and 300 ineligible for food assistance) were interviewed before rations were distributed, at 6 months and at 12 months. Data collected included demographics, BMI and food insecurity score (range 0 - 20).
Results: At 6- and 12-month time-points, 488 and 340 subjects were eligible for analysis. Multivariable analysis demonstrated that at 6 months, food security significantly improved in those who received food assistance versus who did not (-3.55 vs -0.16; P < 0.0001); BMI decreased significantly less in the food assistance group than in the non-food group (-0.20 vs -0.66; P = 0.020). At 12 months, food assistance was associated with improved food security (-3.49 vs -1.89, P = 0.011) and BMI (0.22 vs -0.67, P = 0.036). Food assistance was associated with improved adherence to monthly clinic visits at both 6 (P < 0.001) and 12 months (P = 0.033).
Conclusions: Food assistance was associated with improved food security, increased BMI, and improved adherence to clinic visits at 6 and 12 months among people living with HIV in Haiti and should be part of routine care where HIV and food insecurity overlap.

AB Increases in body mass index (BMI) are reported to influence asthma severity and response to treatment. This analysis was designed to explore whether increasing BMI altered the comparative response to treatment with either fluticasone propionate (FP) or montelukast. Two double-blind, randomized, parallel-group trials of 12-weeks duration comparing FP, 88 micrograms, twice daily or montelukast, 10 mg, daily Were evaluated. Subjects with mild-moderate persistent asthma were retrospectively stratified by BMI of <20 kg/m(2) (underweight), 20-24.9 kg/m(2) (normal Weight), 25-29.9 kg/m(2) (overweight), and >= 30 kg/m(2) (obese). Outcomes included mean changes in forced expiratory volume in 1 second (FEV) and morning peak flow, daily albuterol use, and daily symptom scores. There were 1052 subjects evenly distributed between FP and montelukast by baseline parameters, including BMI. FP was statistically superior to montelukast for all BMI categories of normal, overweight, and obese subjects for FEV(1) (p < 0.008), morning peak flow (p < 0.002), albuterol use (p < 0.02), and symptom scores (p < 0.05). FP produced a significantly greater clinical response for normal, overweight, and obese subjects compared with montelukast. Irrespective of BMT, FP appears to be the more effective asthma controller therapy. (Allergy Asthma Proc 31:20-25, 201.0; doi: 10.2500/aap.2010.31.3307)

AB Omalizumab is a novel therapy approved for treating patients with moderate to severe persistent allergic asthma with a serum IgE ranging from 30 to 700 IU/mL. We examined the efficacy of omalizumab as a treatment for IgE-mediated food allergy. An Institutional Review Board-approved prospective pilot study was performed to assess the efficacy of omalizumab in 22 patients with persistent asthma and concomitant IgE-mediated food allergy. All patients showed skin test positivity to foods and experienced allergic food reactions based on history. Patients were interviewed on unintentional and/or unauthorized exposures to sensitized foods, Thirteen female and nine male patients (range, 4-66 years: old; mean, 38 years) were evaluated in a private practice setting. Mean IgE level was 1120.74 IU/mL. Sensitized allergens included fish, shellfish, peanuts, tree nuts, egg, soybean, and wheat. All 22 (100%) patients maintained significant improvement as shown by a decrease/lack of clinical symptoms on reexposure to sensitized foods. Clinical improvement by the sixth dosage of omalizumab (150-300 mg q. 2-4 weeks) was noted by history and physical examination. Eight patients noted a decrease in their food-induced atopic dermatitis, 13 patients noted a decrease in their food-induced asthma symptoms, 3 patients noted a decrease in their food-induced urticaria, 6 patients noted a decrease in their food-induced rhinosinusitis symptoms, and 9 patients showed efficacy for angioedema and/or anaphylaxis. While treating asthma patients with omalizumab, patients subjectively observed a reduction in their concomitant IgE-mediated food allergy symptoms.

AB We compared the predictive value of cerebral perfusion as measured by arterial-spin labeling magnetic resonance imaging (ASL-MRI) with MRI-derived hippocampal volume for determining future cognitive and functional decline and subsequent conversion from mild cognitive impairment to dementia. Forty-eight mild cognitive impairment subjects received structural and ASL-MRI scans at baseline and clinical and neuropsychologic assessments annually. Thirteen subjects became demented during the period of longitudinal observation (2.7 +/- 1.0 y). Cox regression analyses suggest that baseline hippocampal volume [relative risk (RR) = 0.99, P = 0.004], baseline right inferior parietal (RR = 0.64, P = 0.01) and right middle frontal (RR = 0.73, P = 0.01) perfusion were associated with conversion to dementia. Results from linear mixed effects modeling suggest that baseline perfusion from the right precuneus predicted subsequent declines in Clinical Dementia Rating Sum of Boxes (P = 0.002), Functional Activates Questionnaire (P = 0.01), and selective attention (ie, Stroop switching, P = 0.009) whereas baseline perfusion from the right middle frontal cortex predicted subsequent episodic memory decline (ie, total recognition discriminability score from the California Verbal Learning Test, P = 0.03). These results suggest that hypoperfusion as detected by ASL-MRI can predict subsequent clinical, functional, and cognitive decline and may be useful for identifying candidates for future Alzheimer disease treatment trials.

AB The posteromedial cortices and other regions of the "default network'' are particularly vulnerable to the pathology of Alzheimer disease (AD). In this study, we performed functional magnetic resonance imaging (fMRI) to investigate whether the presence of apolipoprotein E (APOE) epsilon 4 allele and degree of memory impairment were associated with the dysfunction of these brain regions. Seventy-five elderly subjects ranging from cognitively normal to mild AD, divided into epsilon 4 carriers and noncarriers, underwent fMRI during a memory-encoding task. Across all subjects, posteromedial and ventral anterior cingulate cortices (key components of the default network) as well as right middle and inferior prefrontal regions demonstrated reduced task-induced deactivation in the epsilon 4 carriers relative to noncarriers. Even among cognitively normal subjects, epsilon 4 carriers demonstrated reduced posteromedial deactivation compared with the noncarriers in the same regions which demonstrated failure of deactivation in AD patients. Greater failure of posteromedial deactivation was related to worse memory performance (delayed recall) across all subjects and within the range of cognitively normal subjects. In summary, the posteromedial cortical fMRI response pattern is modulated both by the presence of APOE epsilon 4 and episodic memory capability. Altered fMRI activity of the posteromedial areas of the brain default network may be an early indicator of risk for AD.

AB Purpose: We evaluated the risk of death from Alzheimer disease (AD) in men with prostate cancer undergoing treatment with or without a luteinizing-hormone releasing hormone (LHRH) agonist.
Methods: Between 1997 and 2007, 6,647 men were treated with brachytherapy for prostate cancer with (N = 1,700) or without (N = 4,947) LHRH agonist therapy. Competing risks multivariable regression was performed to assess whether the use of a LHRH agonist was associated with the risk of death from AD adjusting for the presence of mild AD and age at presentation and known prostate cancer prognostic factors.
Results: After a median follow-up of 4.1 years, 1.2% (81/6,647) of the study cohort died from AD accounting for 16% (81/506) of all observed mortality. There was a significant reduction in the risk of death from AD in men who were treated with a LHRH agonist for a median of 4.0 months as compared with those who were not [adjusted hazard ratio: 0.45 (95% confidence interval, 0.25-0.83); P = 0.01].
Conclusions: LHRH agonist use as compared with no use in men with prostate cancer was associated with a decreased risk of death from AD.

While clinical validation remains a goal for many potential Alzheimer disease biomarkers, the rapid proliferation of markers has sparked comparative efforts as well. New data acquisition methods and sophisticated image-processing algorithms are poised to make a substantial impact on our ability to make precise measurements of the structure and function of regions within the living human brain and their connections and chemical composition. This commentary provides a perspective on a recently published paper and how it illustrates progress and challenges in the field.

AB Recent advances in biomarkers for Alzheimer's disease (AD) now allow the visualization of one of the hallmark pathologies of AD in vivo, and combination biomarker profiles can now approximate the diagnostic accuracy of autopsy in patients with dementia. Biomarkers are already employed in clinical trials in prodromal AD for both subject selection and in monitoring therapeutic response. Ultimately the greatest utility of biomarkers may be in the preclinical stages of AD, to identify and track progression of the disease prior to significant cognitive impairment, at the point when disease-modifying therapies are likely to be most efficacious.

AB The strongest known risk factors for late-onset Alzheimer disease (LOAD) remain a positive family history and the APOE epsilon 4 allele. van Exel and colleagues used these known risk factors to identify high- and low-risk samples of middle-aged persons in whom they compared levels of inflammatory and vascular risk factors. They observed that, compared with controls, middle-aged off spring of families with a parental history of LOAD had higher blood pressures, lower ankle-brachial indices (measure of peripheral atherosclerosis), and increased production of proinflammatory cytokines in lipopolysaccharide-stimulated whole blood samples, associations that were independent of APOE genotype. This study adds to the growing body of evidence linking inflammatory mechanisms to Alzheimer disease risk and, especially when considered in light of the recently described association of genetic variation in the complement receptor 1 (CR1) gene with LOAD, suggests that inflammatory biomarkers (whether causal or incidental) could be measured and perhaps used to risk-stratify middle-aged persons for early preventive and therapeutic interventions.

TI Extent of ST-segment resolution after fibrinolysis adds improved risk
stratification to clinical risk score for ST-segment elevation
myocardial infarction
SO AMERICAN HEART JOURNAL

DT Article

REPERFUSION; THROMBOLYSIS; MORTALITY; TRIAL; RECLASSIFICATION;
ANGIOPLASTY; CLOPIDOGREL
AB Background The TIMI risk score (TRS) for ST-segment elevation myocardial infarction (STEMI) is a convenient validated clinical risk score for predicting mortality. Although not part of the risk score, ST-segment resolution (STRes) may provide a simple method of risk stratification based on the response to reperfusion. We sought to determine whether STRes provides incremental risk stratification to the TIMI risk score.
Methods The Clopidogrel as Adjunctive Reperfusion Therapy-Thrombolysis in Myocardial Infraction (CLARITY-TIMI 28) trial randomized STEMI patients receiving fibrinolysis to clopidogrel or placebo. A total of 2,340 patients had electrocardiograms (ECGs) valid to calculate STRes at 90 minutes, which was defined as complete (>70%), partial (30%-70%), or no resolution (30%). TRS was defined as low (0-2), medium (3-4), and high (>= 5). Clinical follow-up was through 30 days. Results were validated in 2,743 patients from the ExTRACT-TIMI 25 study.
Results The degree of STRes at 90 minutes after fibrinolysis correlated in a stepwise fashion with death or heart failure (5.1% complete STRes, 8.9% partial STRes, 13.4% no STRes, P < .001). Furthermore, the degree of STRes provided a consistent and significant gradient of risk across all risk score categories (low, medium, or high) and significantly improved the discriminatory ability of TIMI risk score to predict death or heart failure (c-statistic 0.69 for TIMI risk score alone and 0.74 with STRes added to the model, P < .001). With the inclusion of STRes to the TIMI risk score, 913 patients (39%) were reclassified to higher or lower risk groups, and the net reclassification improvement (NRI) was highly significant (P < .001). In the ExTRACT-TIMI 25 trial, addition of the STRes improved also the c-statistic (P = .012) and NRI (P < .001).
Conclusions The extent of STRes based on routinely obtained ECGs is an independent predictor of death and heart failure when used together with the TIMI risk score and significantly improves the ability to risk stratify patients after fibrinolysis. (Am Heart J 2010; 159: 55-62.)

TI Predictors of Short-Term (Seven-Day) Cardiac Outcomes After Emergency
Department Visit for Syncope
SO AMERICAN JOURNAL OF CARDIOLOGY
LA English
DT Article
ID RISK STRATIFICATION; PROSPECTIVE VALIDATION; EXTERNAL VALIDATION; RULE;
SCORE; PROGNOSIS; ADMISSION
AB Syncope is a common reason for emergency department (ED) visits, and patients are often admitted to exclude syncope of cardiovascular origin. Population-based data on patterns and predictors of cardiac outcomes may improve decision-making. Our objective was to identify patterns and predictors of short-term cardiac outcomes in ED patients with syncope. Administrative data from an integrated health system of 11 Southern California EDs were used to identify cardiac outcomes after ED presentation for syncope from January 1, 2002, to December 31, 2005. Syncope and cause of death were identified by codes from the International Classification of Disease, Ninth Revision. Cardiac outcomes included cardiac death and hospitalization or procedure consistent with ischemic heart disease, valvular disease, or arrhythmia. Predictors of cardiac outcomes were identified through multivariate logistic regression. There were 35,330 adult subjects who accounted for 39,943 ED visits for syncope. Risk of cardiac outcome sharply decreased following the 7 days after syncope. A 7-day cardiac outcome occurred in 893 cases (3%). Positive predictors of 7-day cardiac outcomes included age >= 60 years, male gender, congestive heart failure, ischemic heart disease, cardiac arrhythmia, and valvular heart disease. Negative predictors included dementia, pacemaker, coronary revascularization, and cerebrovascular disease. There was an age-dependent relation between 7-day cardiac outcomes and arrhythmia and valvular disease, with younger patients (<60 years of age) having greater risk of an event compared to their same-age counterparts. In conclusion, ED decision-making should focus on risk of cardiac event in the first 7 days after syncope and special attention should be given to younger patients with cardiac co-morbidities.

AB Vitamin D may protect against cardiovascular disease, but its association with cardiac function is unclear. The aim of this study was to examine the associations of serum 25-hydroxyvitamin D (25[OH]D) with heart rate, systolic blood pressure, and the rate pressure product (RPP). Data analyses were carried out on 27,153 participants aged >= 20 years, with measurements of serum 25(OH)D, heart rate (from radial pulse), and systolic blood pressure, in the National Health and Nutrition, Examination Surveys (NHANES) carried out from 1988 to 1994 and from 2001 to 2006. RPP was calculated as heart rate times systolic blood pressure. Results were adjusted for age, gender, race or ethnicity, body mass index, physical activity, tobacco smoking, co-morbidities, and blood pressure treatment. Compared to participants with 25(OH)D >= 35 ng/ml, the adjusted mean +/- SE heart rate was significantly (p <0.001) higher, by 2.1 +/- 0.6 beats/min, in participants with 25(OH)D <10.0 ng/ml, while mean systolic blood pressure was 1.9 +/- 0.8 mm Hg higher (p <0.05) for participants with 25(OH)D <10.0 ng/ml and 1.7 +/- 0.6 mm Hg higher (p <0.01) for those with 25(OH)D of 10.0 to 14.9 ng/ml. As a consequence, adjusted mean RPP was 408 +/- 110 beats/min . mm Hg higher (p <0.001) for participants with 25(OH)D <10.0 ng/ml and 245 +/- 80 beats/min . mm Hg higher (p <0.01) for participants with 25(OH)D of 10.0 to 14.9 ng/ml, compared to those with 25(OH)D 35 ng/ml. In conclusion, these results show that low serum 25(OH)D levels are associated with increased heart rate, systolic blood pressure, and RPP and suggest that low vitamin D status may increase cardiac work. Vitamin D intervention studies are required to confirm these findings. (C) 2010 Elsevier Inc. All rights reserved. (Am J Cardiol 2010;105:122-128)

TI Safety of Regadenoson in Patients with End-Stage Renal Disease
SO AMERICAN JOURNAL OF CARDIOLOGY
LA English
DT Article
ID ADENOSINE; AGONIST; SPECT
AB Regadenoson is a selective A(2A) receptor agonist that was recently approved by the Food and Drug Administration for vasodilator stress myocardial perfusion imaging. Because the drug is cleared by renal excretion, its safety in patients with end-stage renal disease (ESRD) needs to be determined. We studied 277 consecutive patients with ESRD who had undergone regadenoson stress gated single photon emission computed tomography myocardial perfusion imaging and compared their side effect profile and safety outcome to those of 134 patients with normal kidney function. The ESRD group included 164 men (59%) and the control group included 73 men (54%; p = NS). The patients with ESRD were younger than the controls (52 11 years vs 61 +/- 12 years; p <0.001). The myocardial perfusion imaging findings were abnormal in 53 patients (19%) with ESRD and in 24 patients in the control group (18%; p = NS). The left ventricular ejection fraction was 57 +/- 12% in the ESRD group and 64 +/- 12% in the control group (p <0.001). The changes in heart rate and systolic blood pressure (from baseline to peak stress) were 20 +/- 12 beats/min versus 22 +/- 13 beats/min and -11 +/- 24 mm Hg versus 12 +/- 23 mm Hg in the ESRD and control groups, respectively (p = NS for both). Very few patients in either group reported symptoms during the stress test. No medication-related hospitalizations, serious events, or death occurred in either group within 30 days of the study. In conclusion, this is the first study to document the safety of regadenoson in a large number of patients with ESRD. The drug was well tolerated, and the hemodynamic and side effect profiles were similar to those of patients with normal renal function. (C) 2010 Elsevier Inc. All rights reserved.

TI Predictors of Annual Pharmaceutical Costs in Australia for
Community-Based Individuals with, or at Risk of, Cardiovascular Disease
Analysis of Australian Data from the REACH Registry
SO AMERICAN JOURNAL OF CARDIOVASCULAR DRUGS
LA English
DT Article
ID HEALTH-CARE COSTS; SERVICES USE; HYPERTENSION; OBESITY;
ATHEROTHROMBOSIS; PREVALENCE; CORONARY; IMPACT; AGE
AB Background: Cardiovascular disease (CVD) remains a leading cause of death across the world and poses a significant economic burden. Research regarding per-person use and cost of cardiovascular pharmaceuticals in Australia, as well as potential predictors of pharmaceutical costs in populations using the 'bottom up' costing approach, is limited. Previous studies have adopted 'top down' costing approaches and have been based largely on hypothetical examples and considered only inpatient settings.
Objective: To determine the distribution of pharmaceutical costs (from a governmental perspective) related to each cardiovascular risk factor for individuals with, or at high risk of, CVD by analysing data for Australian participants enrolled in the Reduction of Atherothrombosis for Continued Health (REACH) Registry.
Methods: 2873 participants were recruited for the REACH Registry through 273 general (primary care) practices in Australia. Included among data collected at baseline was a cardiovascular medicines review. Average weighted costs per person were estimated using Government-reimbursed prices (2007). Annual costs were stratified by sex, age, disease group and other co-morbidities. A multivariate linear regression model was utilized to reveal the predictors of the pharmaceutical costs.
Results: The average annual median cost of cardiovascular pharmaceuticals per person was Australian dollars ($A)1310. Use of lipid-lowering agents, non-aspirin (acetylsalicylic acid) antiplatelet agents and thiazolidinediones (glitazones) added significantly to the average annual per-person costs. The multivariate regression model showed that the predictors of annual pharmaceutical costs were dyslipidemia (beta coefficient value [marginal annual cost associated with a condition] $A691; p < 0.001), hypertension ($A346; p < 0.001), vascular disease ($A340; p < 0.001), diabetes mellitus ($A298; p < 0.001), and obesity ($A52; p = 0.03). The same predictors, together with sex, were shown to have an impact on the number of medicines used.
Conclusions: Among community-based Australians with, or at risk of, CVD, independent drivers of annual cardiovascular pharmaceutical costs are dyslipidemia (which accounts for half of per-person costs), followed by hypertension, established CVD, and diabetes. Obesity also independently adds to the cost of cardiovascular pharmaceuticals in community-based Australians with, or at risk of, CVD.

TI Efficacy and Tolerability of a Cosmetically Acceptable Coal Tar Solution
in the Treatment of Moderate Plaque Psoriasis A Controlled Comparison
with Calcipotriene (Calcipotriol) Cream
SO AMERICAN JOURNAL OF CLINICAL DERMATOLOGY
LA English
DT Article
ID QUALITY-OF-LIFE; THERAPY; EXOREX; ADULTS
AB Background: Topical coal tar is a well known and effective treatment for psoriasis, but the messiness, staining, odor, and inconvenience associated with its use make patient satisfaction and compliance a challenge.
Objective: To determine the efficacy, patient tolerability, and cosmetic acceptability of a new topical liquor carbonis distillate (LCD) 15% solution compared with calcipotriene (calcipotriol) cream in patients with moderate, chronic plaque psoriasis.
Study Design: A randomized, single-blind, active-controlled, parallel-group, clinical trial consisting of a 12-week treatment phase and a 6-week post-treatment follow-up phase.
Setting: Outpatient dermatology research unit in an academic hospital.
Patients: Sixty adults with moderate, chronic plaque psoriasis (3-15% body surface area affected) not receiving other psoriasis therapies.
Intervention: Patients were randomized to apply either an LCD 15% solution (Psorent (R)) or a commercially available calcipotriene 0.005% cream (Dovonex (R)) to their psoriasis areas (excluding the head) twice daily at home for 12 weeks.
Assessments: A blinded investigator evaluated the patients' psoriasis using a modified Psoriasis Area and Severity Index (PASI) that excluded the head, and a Physician's Global Assessment (PGA) scale at weeks 0 (baseline), 2, 4, 8, and 12 (end of treatment), and 18 (6 weeks after treatment was withdrawn). Patients assessed their psoriasis symptoms and quality of life and completed a cosmetic acceptability survey about their medication.
Outcome Measures: The changes in the baseline PASI scores after 12 weeks of treatment were compared between LCD and calcipotriene groups. Additional comparisons were performed for success rates during treatment (PASI 75 and PASI 50), changes in PGA scores, patient-reported psoriasis symptom scores, patients' quality-of-life scores, and recurrence rates during post-treatment follow-up.
Results: Both treatment groups showed improvement in psoriasis severity and quality of life. However, the LCD group had greater mean reductions in PASI scores: 58% vs 37% in the calcipotriene group (p <0.05) at week 12. Additionally, the LCD group had more patients (14/27) with absent or minimal psoriasis on the PGA scale than the calcipotriene group (6/28) by the end of treatment (p <0.05). LCD-treated patients also maintained their improvement better than calcipotriene-treated patients through week 18 after treatment was withdrawn for 6 weeks. Both treatments were well tolerated and cosmetically acceptable to patients.
Conclusion: The newly formulated LCD solution, applied twice daily at home for 12 weeks, was more effective and as well tolerated and cosmetically acceptable as the calcipotriene cream over 12 weeks of treatment and 6 weeks of follow-up. The LCD solution is a patient-accepted and effective corticosteroid-sparing treatment alternative for psoriasis patients.

AB Primary cutaneous marginal zone lymphoma (MZL) is a common B-cell lymphoma of skin and is characterized by an infiltrate of neoplastic marginal zone B cells typically within the marginal zones of reactive lymphoid follicles and the interfollicular region. However, in our experience, many cases have underemphasized features such as marked plasmacytic differentiation and/or a prominent T-cell component, which may obscure the neoplastic B cells and lead to misdiagnosis We wanted to draw attention to these features and have studied 15 cases of MZL with marked plasmacytic differentiation, 10 of which had numerous T cells, some with cytologic atypia, and few B cells in the interfollicular region. Plasma cells were monotypic in all cases by in situ hybridization. By polymerase chain reaction, 6 of 8 T cell-rich cases had an IGH gene rearrangement, and none were clonal for T-cell receptor gene We discuss the terminology, morphologic features, molecular profile, behavior, and differential diagnosis of cutaneous MZL.

AB Background: Patients' substance use problems are a particularly understudied aspect of psychosocial variables in cancer treatment. Objectives: The specific hypothesis tested was that lifetime substance use disorders increased the risk of adverse outcome, in the context of other psychosocial and clinical characteristics demonstrated in other studies to have an impact on treatment outcome. Method: Prospective cohort study of 106 adults with chronic myelogenous leukemia or primary myelodysplastic syndrome. None satisfied criteria for current substance abuse or dependence, but the lifetime rates of substance use disorders in this sample were 28% for alcohol, 12% for cannabis, and 9% for cocaine. Results: Participants received treatment as directed by their physicians, and were followed until death or the end of the study (median 1.5 years). Twenty-eight died. Multivariate survival analysis identified three predictors of outcome: lifetime cocaine use, associated with a six-fold increased risk of death (p = .04), and two protective variables, baseline hemoglobin (p = .002) and estimated intelligence quotient (IQ) (p = .04). Conclusion: The results of this study highlight the potential significance of substance use disorders, and lifetime cocaine diagnoses in particular, on treatment outcome for people with chronic myelogenous leukemia or myelodysplastic syndrome. Whereas neither lifetime alcohol nor cannabis use were associated with survival on either the univariate or multivariate models of survival, lifetime cocaine diagnoses were associated with significant six-fold increased risk of death (p = .04).

INFECTIONS
AB Objective: The study aimed to determine if emergency department (ED) administered antibiotics for patients discharged home with nonpneumonia acute respiratory tract infections (ARIs) have increased since national pneumonia performance measure implementation, including antibiotic administration within 4 hours of arrival.
Methods: Design: Time series analysis. Setting: Six university and 7 Veterans Administration EDs participating in the Improving Antibiotic Use for Acute Care Treatment (IMPAACT) trial (randomized educational intervention to reduce antibiotics for bronchitis). Participants: Randomly selected adult (age > 18 years) ED visits for acute cough, diagnosed with nonpneumonia ARIs, discharged home during winters (November-February) of 2003 to 2007. Main outcome: Time trend in ED-administered antibiotics, adjusted for patient demographics, comorbidities, vital signs, ED length of stay, IMPAACT intervention status, geographic region, Veterans Administration/university setting, and site and provider level clustering.
Results: Six thousand four hundred seventy-six met study criteria. Three hundred ninety-four (6.1%) received ED-administered antibiotics. Emergency department administered antibiotics did not increase across the study period among all IMPAACT sites (odds ratio [OR], 0.88; 95% confidence interval [CI], 0.76-1.01) after adjusting for age, congestive heart failure history, temperature higher than 100 F, heart rate more than 100, blood cultures obtained, diagnoses, and ED length of stay. The ED-administered antibiotic rate decreased at IMPAACT intervention (OR, 0.80; 95% CI, 0.69-0.93) but not nonintervention sites (OR, 1.04; 95% CI, 0.91-1.19). Adjusted proportions receiving ED-administered antibiotics were 6.1% (95% CI, 2.7%-13.2%) for 2003 to 2004; 4.8% (95% CI, 2.2%-10.0%) for 2004 to 2005; 4.6% (95% CI, 2.7%-7.8%) for 2005 to 2006; and 4.2% (95% CI, 2.2%-8.0%) for 2006 to 2007.
Conclusions: Emergency department administered antibiotics did not increase for patients with acute cough discharged home with nonpneumonia ARIs since pneumonia antibiotic timing performance measure implementation in these academic EDs. (C) 2010 Elsevier Inc. All rights reserved.

AB Objective: The aim of the study was to evaluate use of physician assistants (PAs) and nurse practitioners (NPs) in US emergency departments (EDs).
Methods: We analyzed visits from the 1993 to 2005 National Hospital Ambulatory Medical Care Survey, seen by midlevel provider (MLP), and compared characteristics of MLP visits to those seen by physicians only.
Results: From 1993 to 2005, 5.2% (95% CI, 4.6%-5.8%) of US ED visits were seen by PAs and 1.7% (95% CI, 1.5%-2.0%) by NPs. During the study period, PA visits rose from 2.9% to 9.1%, whereas NP visits rose from 1.1% to 3.8% (both P(trend) < .001). Compared to physician only visits, those seen only by MLPs arrived by ambulance less frequently (6.0% vs 15%), had lower urgent acuity (37% vs 59%), and were admitted less often (3.0% vs 13%).
Conclusions: Midlevel provider use has increased in US EDs. Their involvement in some urgent visits and those requiring admission suggests that the role of MLPs extends beyond minor presentations. (C) 2010 Elsevier Inc. All rights reserved.

AB Vascular abnormalities may exist before clinical hypertension. Using Poisson regression, the authors studied the association of coronary artery calcium (CAC), common carotid intima-media thickness (CIMT), aortic distensibility, and large and small arterial elasticity with incident hypertension among 2,512 normotensive US adults free of cardiovascular disease. Incidence rate ratios for incident hypertension (blood pressure >= 140/90 mm Hg or new antihypertensive medication) were calculated. Increased CAC was associated with incident hypertension in demographics-adjusted models (incidence rate ratio (IRR) = 1.35, 95% confidence interval (CI): 1.04, 1.75; IRR = 1.35, 95% CI: 1.02, 1.78; and IRR = 1.59, 95% CI: 1.12, 2.25 for CAC scores of 30-99, 100-399, and >= 400, respectively) but was attenuated after further adjustment. Increased common CIMT was associated with incident hypertension (IRR = 1.77, 95% CI: 1.28, 2.46 for quintile 4; IRR = 1.80, 95% CI: 1.28, 2.53 for quintile 5). Participants with the lowest, compared with the highest, aortic distensibility had an increased risk of hypertension (IRR = 1.75, 95% CI: 1.10, 2.79), as did those with the lowest large arterial elasticity (IRR = 1.49, 95% CI: 1.11, 1.99). Lower small arterial elasticity was incrementally associated with incident hypertension starting at quintile 2 (IRR = 2.01, 95% CI: 1.39, 2.91; IRR = 2.47, 95% CI: 1.71, 3.57; IRR = 2.73, 95% CI: 1.88, 3.95; and IRR = 2.85, 95% CI: 1.95, 4.16). Structural and functional vascular abnormalities are independent predictors of incident hypertension. These findings are important for understanding the pathogenesis of hypertension.

AB To estimate the net effect of imperfectly measured highly active antiretroviral therapy on incident acquired immunodeficiency syndrome or death, the authors combined inverse probability-of-treatment-and-censoring weighted estimation of a marginal structural Cox model with regression-calibration methods. Between 1995 and 2007, 950 human immunodeficiency virus-positive men and women were followed in 2 US cohort studies. During 4,054 person-years, 374 initiated highly active antiretroviral therapy, 211 developed acquired immunodeficiency syndrome or died, and 173 dropped out. Accounting for measured confounders and determinants of dropout, the weighted hazard ratio for acquired immunodeficiency syndrome or death comparing use of highly active antiretroviral therapy in the prior 2 years with no therapy was 0.36 (95% confidence limits: 0.21, 0.61). This association was relatively constant over follow-up (P = 0.19) and stronger than crude or adjusted hazard ratios of 0.75 and 0.95, respectively. Accounting for measurement error in reported exposure using external validation data on 331 men and women provided a hazard ratio of 0.17, with bias shifted from the hazard ratio to the estimate of precision as seen by the 2.5-fold wider confidence limits (95% confidence limits: 0.06, 0.43). Marginal structural measurement-error models can simultaneously account for 3 major sources of bias in epidemiologic research: validated exposure measurement error, measured selection bias, and measured time-fixed and time-varying confounding.

TI PML Nuclear Body Component Sp140 Is a Novel Autoantigen in Primary

AB OBJECTIVES: Some patients with primary biliary cirrhosis (PBC) have antinuclear antibodies (ANAs). These ANAs include the "multiple nuclear dots" (MND) staining pattern, targeting promyelocytic leukemia protein (PML) nuclear body (NB) components, such as "speckled 100-kD" protein (Sp100) and PML. A new PML NB protein, designated as Sp140, was identified using serum from a PBC patient. The aim of this study was to analyze the immune response against Sp140 protein in PBC patients.
METHODS: We studied 135 PBC patients and 157 pathological controls with type 1 autoimmune hepatitis, primary sclerosing cholangitis, and systemic lupus erythematosus. We used indirect immunofluorescence and a neuroblastoma cell line expressing Sp140 for detecting anti-Sp140 antibodies, and a commercially available immunoblot for detecting anti-Sp100 and anti-PML antibodies.
RESULTS: Anti-Sp140 antibodies were present in 20 (15%) PBC patients but not in control samples, with a higher frequency in antimitochondrial antibody (AMA)-negative cases (53 vs. 9%, P<0.0001). Anti-Sp140 antibodies were found together with anti-Sp100 antibodies in all but one case (19 of 20, 90%) and with anti-PML antibodies in 12 (60%) cases. Anti-Sp140 positivity was not associated with a specific clinical feature of PBC.
CONCLUSIONS: Our study identifies Sp140 as a new, highly specific autoantigen in PBC for the first time. The very frequent coexistence of anti-Sp140, anti-Sp100 and anti-PML antibodies suggests that the NB is a multiantigenic complex in PBC and enhances the diagnostic significance of these reactivities, which are particularly useful in AMA-negative cases.

AB Purpose. Sexually transmitted disease (STD) rates have continued to increase among men who have sex with men (MSM). The present study used qualitative methods to assess sources of human immunodeficiency virus (HIV)/STD information and responses to HIV/STD prevention messages among MSM. This was done to understand how to design more effective media campaigns on HIV/STD prevention and testing for this population.
Design. One-on-one semistructured, qualitative interviews and a brief demographic written survey were conducted.
Setting. A Massachusetts community-based organisation specializing in HIV/AIDS healthcare.
Participants. A novel, modified, respondent-driven sampling method was used to recruit a diverse sample of 50 Massachusetts MSM between January and April 2005; qualitative interviews were conducted until redundancy in responses was achieved.
Method. Qualitative data were analyzed using content analysis. NVIVO software was used to organize transcripts, identify themes, and report frequency of responses.
Results. Respondents reported having derived information on sexual health from multiple media sources. Direct outreach, gay- and HIV-centered organizations, print and broadcast media, public transportation ads, and the Internet held the greatest potential for dissemination. Primary care providers were also frequently seen as trusted sources of HIV/STD prevention information. Ideas for content often included having "people just like you" in ads.
Conclusion. Health message that focus on getting tested for HIV and STDs, practicing safe sex, incorporating straightforward and accurate information on prevention may be the most acceptable to MSM. Providers should be proactive in disseminating information about HIV/STD prevention. (Am J Health Promot 2010;24[3]:170-177.)

AB Acute chest syndrome (ACS) causes significant morbidity and mortality in sickle cell disease. The role of corticosteroids is unclear. The objectives of our study were to examine the variation between hospitals in their use of corticosteroids for ACS, describe characteristics associated with corticosteroids, and investigate the association between corticosteroids, length of stay, and readmission. We performed a retrospective examination of 5,247 hospitalizations for ACS between January 1, 2004, and June 30, 2008, at 32 hospitals in the Pediatric Health Information System database. We used multivariate regression to examine the variability in the use of corticosteroids adjusting for hospital case mix, identify factors associated with corticosteroid use, and evaluate the association of corticosteroids with length of stay and 3-day readmission rates controlling for propensity score. Corticosteroid use varied greatly by hospital (10-86% among all patients, 18-92% in patients with asthma). Treatment with corticosteroids was associated with comorbid asthma (OR 3.9, 95% CI: 3.2-4.8), inhaled steroids (OR 1.4, 95% CI: 1.1-1.7), bronchodilators (OR 3.2, 95% CI: 2.5-4.2), nitric oxide (OR 2.4, 95% CI: 1.2-5.0), oxygen (OR 2.3, 95% CI: 1.8-2.9), ICU (OR 1.7, 95% CI 1.3-2.3), ventilation (OR 2.0, 95% CI: 1.4-2.8), APR-DRG severity level (OR 1.4, 95% CI: 1.2-1.6), and discharge year (OR 0.86, 95% CI: 0.80-0.92). Corticosteroids were associated with an increased length of stay (25%, 95% CI: 14-38%) and a higher 3-day readmission rate (OR 2.3, 95% CI: 1.6-3.4), adjusted for confounding. Hospitals vary greatly in the use of corticosteroids for ACS, even in patients with asthma. Clear evidence of the efficacy and toxicity of corticosteroid treatment in ACS may reduce variation in care. Am. J. Hematol. 85:24-28, 2010. (C) 2009 Wiley-Liss, Inc.

PREVALENCE; TRIAL
AB BACKGROUND
Hypertension (HTN) is a prevalent and important risk factor for both cardiovascular and all-cause mortality. Depression is often present in hypertensive patients and has also been associated with increased mortality risk. The aim of this study was to evaluate the association of depressive symptoms with all-cause mortality and ischemic heart disease (IHD) mortality among adults with self-reported HTN.
METHODS
We studied 10,025 participants in the National Health and Nutrition Epidemiologic Follow-up Study (NHANES 1) who were alive and interviewed in 1982 and had complete data for the Center for Epidemiologic Studies Depression Scale (CES-D). Four groups were identified based screening status at initial interview: (i) no HTN, no depression (reference group); (ii) HTN, no depression; (iii) no HTN, depression; and (iv) both HTN and depression. Cox proportional hazards regression was used to calculate multivariate-adjusted hazard ratios (HRs) of death for each group.
RESULTS
Over an average of 8 years (83,943 person-years) of follow-up, patients with both self-reported HTN and depressive symptoms had the highest multivariate-adjusted HR for all-cause mortality at 1.39 (95% confidence interval (CI) 1.14,1.69) as well as for IHD mortality at 1.59 (95% CI 1.08, 2.34). In post hoc analysis, nondepressed hypertensive patients had significantly lower adjusted HR for all-cause mortality compared to depressed hypertensive patients (HR 0.85; 95% CI 0.73-1.00), but the HR for IHD mortality was not significant (HR 0.87,95% CI 0.63-1.20).
CONCLUSION
Comorbid depressive symptoms are associated with increased all-cause mortality in patients with self-reported HTN.

AB Objective: To examine the impact of a medication copayment increase on adherence to diabetes, hypertension, and hyperlipidemic medications.
Study Design: Retrospective pre-post observational study.
Methods: This study compared medication adherence at 4 Veterans Affairs medical centers between veterans who were exempt from copayments and propensity-matched veterans who were not exempt. The diabetes sample included 1069 exempt veterans and 1069 nonexempt veterans, the hypertension sample included 3545 exempt veterans and 3545 nonexempt veterans, and the sample of veterans taking statins included 2029 exempt veterans and 2029 nonexempt veterans. The main outcome measure was medication adherence 12 months before and 23 months after the copayment increase. Adherence differences were assessed in a difference-in-difference approach by using generalized estimating equations that controlled for time, copayment exemption, an interaction between time and copayment exemption, and patient demographics, site, and other factors.
Results: Adherence to all medications increased in the short term for all veterans, but then declined in the longer term (February-December 2003). The change in adherence between the preperiod and the postperiod was significantly different for exempt and nonexempt veterans in all 3 cohorts, and nonadherence increased over time for veterans required to pay copayments. The impact of the copayment increase was particularly adverse for veterans with diabetes who were required to pay copayments.
Conclusion: A $5 copayment increase (from $2 to $7) adversely impacted medication adherence for veterans subject to copayments taking oral hypoglycemic agents, antihypertensive medications, or statins. (Am J Manag Care. 2010; 16(1): e20-e34)

AB Clinical and molecular analyses of Costello syndrome are proceeding at a rapid pace, including the delineation of the adult phenotype. We designed a two-part survey in order to describe the quality of life (QoL) of older individuals with Costello syndrome. The survey consisted of the Costello syndrome quality of life (CSQoL): Caregiver Questionnaire, to obtain objective information such as skills, activities, and medical issues from caregivers; and the CSQoL:Self-Questionnaire assessing subjective information including self-esteem, life satisfaction, and interpersonal relations from affected individuals. Thirteen of 18 (72%) individuals with Costello syndrome (age 16-34 years, mean 22 years) and caregiver pairs responded. The data were analyzed to study day-to-day life, and to determine potential impediments on QoL for older individuals with Costello syndrome. The CSQoL:Caregiver total scores were significantly lower than the CSQoL:Self total scores as demonstrated by the Wilcoxon Signed Ranks Test (P < 0.008). The CSQoL:Caregiver total scores appear negatively correlated with total number of medical issues (r = - 0.549; P = 0.065). No association was found between the CSQoL:Self scores and total number of medical issues (r = - 0.107; P = 0. 769). Four impediments to QoL for individuals with Costello syndrome were identified: relationships outside of their immediate circle of family and friends, lack of independence, male gender, and the presence of major medical issues. This information may be useful to the families and health care professionals of adults with Costello syndrome. As a measurable characteristic, QoL may have utility as a metric in future therapeutic trials. (C) 2009 Wiley-Liss, Inc.

AB We previously reported genome-wide significant evidence for linkage between chromosome 6q and bipolar I disorder (BPI) by performing a meta-analysis of original genotype data from 11 genome scan linkage studies. We now present follow-up linkage disequilibrium. mapping of the linked region utilizing 3,047 single nucleotide polymorphism (SNP) markers in a case-control sample (N = 530 cases, 534 controls) and family-based sample (N = 256 nuclear families, 1,301 individuals). The strongest single SNP result (rs6938431, P = 6.72 x 10(-5)) was observed in the case-control sample, near the solute carrier family 22, member 16 gene (SLC22A16). In a replication study, we genotyped 151 SNPs in an independent sample (N = 622 cases, 1,181 controls) and observed further evidence of association between variants at SLC22A16 and BPI. Although consistent evidence of association with any single variant was not seen across samples, SNP-wise and gene-based test results in the three samples provided convergent evidence for association with SLC22A16, a carnitine transporter, implicating this gene as a novel candidate for BPI risk. Further studies in larger samples are warranted to clarify which, if any, genes in the 6q region confer risk for bipolar disorder. (C) 2009 Wiley-Liss, Inc.

AB First-degree relatives of persons with bipolar disorders (BDs) carry elevated risk for the illness, and manifest deficits in attention and memory (possible "endophenotypes"). However, there is only one published functional magnetic resonance imaging (fMRI) study of candidate endophenotypes in BD. We used fMRI to examine brain function in BD and in first-degree relatives performing a 2-back working memory (WM) task, and correlated brain activity with mood measures taken at the scanning session. Subjects (age 32-46) were 19 persons with BD, 18 unmedicated, non-psychotic first-degree relatives (RELs) of persons with BD, and 19 matched controls, ascertained from a long-term follow-up of a prenatal cohort study in New England. fMRI signal during 2-back and 0-back WM tasks was measured on a Siemens 1.5T MR scanner. fMRI data were analyzed using SPM-2. Persons with BD and RELs failed to suppress activation in the left anterior insula (BA 13) during WM, whereas controls suppressed activation. Compared to controls, RELs also failed to suppress activation in the orbitofrontal cortex (OFC) and superior parietal cortex. Controls and RELs exhibited greater activation than BD individuals in the left frontopolar cortex (BA 10) during WM. Results remained significant after controlling for confounders except for mild attenuation of OFC findings. Significant correlations between brain activity, mood, and WM suggest that activity in WM circuits is affected by activity in emotion-regulatory circuits. Persons with BD and RELs exhibit altered activity in the frontopolar cortex and insula, which may represent biomarkers of genetic risk for BD. (C) 2009 Wiley-Liss, Inc.

AB Conflicting results have been reported as to whether genetic variations (Val66Met and C270T) of the brain-derived neurotrophic factor gene (RDNF) confer susceptibility to Alzheimer's disease (AD). We genotyped these polymorphisms in a Japanese sample of 657 patients with AD and 525 controls, and obtained weak evidence of association for Val66Met (P = 0.063), but not for C270T. After stratification by sex, we found a significant allelic association between Val66Met and AD in women (P = 0.017), but not in men. To confirm these observations, we collected genotyping data for each sex from 16 research centers worldwide (4,711 patients and 4,537 controls in total). The meta-analysis revealed that there was a clear sex difference in the allelic association; the Met66 allele confers susceptibility to AD in women (odds ratio = 1.14, 95% CI 1.05-1.24, P = 0.002), but not in men. Our results provide evidence that the Met66 allele of BDNF has a sexually dimorphic effect on susceptibility to AD. (C) 2009 Wiley-Liss, Inc.

AB Schizophrenia is a genetically complex illness with heterogeneous clinical presentation, including variable age of onset. In this study, the heritability, or proportion of variation in age of onset of psychotic symptoms due to genetic factors, was estimated using a maximum likelihood method. The subjects were 717 members of families with more than one member affected with schizophrenia from Mexican and Central American populations. Age of onset of psychosis was determined by best-estimate consensus diagnosis based on the Diagnostic Interview for Genetic Studies, Family Interview for Genetic Studies, and each subject's medical records. Mean age of onset was 21.44 years (SD 8.07); 20.55 years for males (SD 6.90), and 22.67 for females (SD 9.34). Variance components were estimated using a polygenic model in the SOLAR software package. The sex of the participant was a significant covariate (P = 0.010) accounting for 0.02 of the total variance in age of onset. The heritability of age of onset of psychosis was 0.33 (SE = 0.09; P = 0.00004). These findings suggest that genetic factors significantly contribute to the age of onset of psychotic symptoms in individuals with schizophrenia and that sex influences this trait as well.

AB Variations in voltage-dependent calcium channel L-type, alpha 1C subunit (CACNA1C) gene have been associated with bipolar disorder in a recent meta-analysis of genome-wide association studies [Ferreira et al., 2008]. The impact of these variations on other psychiatric disorders has not been yet investigated. Caucasian non-Hispanic participants in the STAR(star)D study of treatment for depression for whom DNA was available (N = 1213) were genotyped at two single-nucleotide polymorphisms (SNPs) (rs10848635 and rs1006737) in the CACNA1C gene. We examined putative phenotypic indicators of bipolarity among patients with major depression and elements of longitudinal course suggestive of latent bipolarity. We also considered remission and depression severity following citaloprain treatment. The rs10848635 risk allele was significantly associated with lower levels of baseline agitation (P = 0.03; beta = -0.09). The rs1006737 risk allele was significantly associated with lesser baseline depression severity (P = 0.04; beta = -0.4) and decreased likelihood of insomnia (P = 0.047; beta = -0.22).

AB Tardive dyskinesia (TD) is a movement disorder characterized by involuntary oro-facial, limb, and truncal movements. As a genetic basis for inter-individual variation is assumed, there have been a sizeable number of candidate gene studies. All subjects met diagnostic criteria for schizophrenia and were randomized to receive antipsychotic medications as participants in the Clinical Antipsychotic Trials of Intervention Effectiveness project (CATIE). TD was assessed via the Abnormal Involuntary Movement Scale at regular intervals. Probable TD was defined as meeting Schooler-Kane criteria at any scheduled CATIE visit (207/710 subjects, 29.2%). A total of 128 candidate genes were studied in 710 subjects-2,580 SNPs in 118 candidate genes selected from the literature (e.g., dopamine, serotonin, glutamate, and GABA pathways) and composite genotypes for 10 drug-metabolizing enzymes. No single marker or haplotype association reached statistical significance after adjustment for multiple comparisons. Thus, we found no support for either novel or prior associations from the literature. (C) 2009 Wiley-Liss, Inc.

AB The authors estimated the validity of algorithms for identification of mental health conditions (MHCs) in administrative data for the 133 068 diabetic patients who used Veterans Health Administration (VHA) nationally in 1998 and responded to the 1999 Large Health Survey of Veteran Enrollees. They compared various algorithms for identification of MHCs from International Classification of Diseases, 9th Revision (ICD-9) codes with self-reported depression, posttraumatic stress disorder, or schizophrenia from the survey. Positive predictive value (PPV) and negative predictive value (NPV) for identification of MHC varied by algorithm (0.65-0.86, 0.68-0.77, respectively). PPV was optimized by requiring >= 2 instances of MHC ICD-9 codes or by only accepting codes from mental health visits. NPV was optimized by supplementing VHA data with Medicare data. Findings inform efforts to identify MHC in quality improvement programs that assess health care disparities. When using administrative data in mental health studies, researchers should consider the nature of their research question in choosing algorithms for MHC identification.

TI Diagnosis of Pulmonary Malignancy after Hospitalization for Pneumonia
SO AMERICAN JOURNAL OF MEDICINE
LA English
DT Article
DE Cancer; Incidence; Pneumonia
ID LUNG-CANCER; COMORBIDITY INDEX; VALIDATION; QUALITY; STAGE
AB BACKGROUND: Many physicians recommend that patients receive follow-up chest imaging after the diagnosis of pneumonia to ensure that a pulmonary malignancy is not missed. However, there is little research evidence to support this practice. Our aims were to assess the frequency of the diagnosis of Pulmonary malignancy, and to identify risk factors for pulmonary malignancy following hospitalization for pneumonia.
METHODS: By excluding patients with a prior diagnosis of pulmonary malignancy, we examined the incidence of a new pulmonary malignancy diagnosis in inpatients aged >= 65 years with a discharge diagnosis of pneumonia in fiscal years 2002-2007, and at least 1 year of Department of Veterans Affairs outpatient care before the index admission.
RESULTS: Of 40,744 patients hospitalized with pneumonia, 3760 (9.2%) patients were diagnosed with pulmonary malignancy after their index pneumonia admission. Median time to diagnosis was 297 days, with only 27% diagnosed within 90 days of admission. Factors significantly associated with a new diagnosis of pulmonary malignancy included history of chronic pulmonary disease, any prior malignancy, white race, being married, and tobacco use. Increasing age, Hispanic ethnicity, need for intensive care unit admission, and a history of congestive heart failure, stroke, dementia, or diabetes with complications were associated with a lower incidence of pulmonary malignancy.
CONCLUSION: A small, but clinically important, proportion of patients are diagnosed with pulmonary malignancy posthospitalization for pneumonia. Additional research is needed to examine whether previously undiagnosed pulmonary malignancies might be detected at admission, or soon after, for those hospitalized with pneumonia.

AB Background/Aims: Toll-like receptor 4 (TLR4) and its adaptor protein MyD88 play an important role in ischemia/reperfusion (I/R) injury in the kidney, and pituitary adenylate cyclase-activating polypeptide (PACAP) could ameliorate renal I/R injury. Methods: Primary cultures of proximal tubule epithelial cells (PTEC) were prepared from wild-type and MyD88(-/-) mice, and subjected to hypoxia in vitro. Acute kidney injury (AKI) was induced by I/R in vivo in wild-type mice only. Results: Hypoxia resulted in significant increases in cytokine production and apoptosis/necrosis in wild-type PTEC, but these responses were markedly blunted in MyD88(-/-) PTEC. Treatment with PACAP38 before or after hypoxia further suppressed the hypoxia-induced cytokine responses and apoptosis in both MyD88(+/+) and MyD88(-/-)PTEC cultures. PACAP38 significantly inhibited TLR4/MyD88/TRAF6 as well as TRIF and IRF3 expression in mouse kidney and PTEC, and inhibited the secretion and mRNA expression of cytokines in kidneys from mice after I/R, paralleling the cytokine responses in vitro. Moreover, treatment with PACAP38 protected mice from renal failure, histological damage, neutrophil influx and tubule cell apoptosis after I/R. Conclusion: Our data reveal that the TLR4-mediated cytokine responses to hypoxia are primarily dependent on MyD88 signaling and highlight the pivotal role of MyD88-dependent mechanisms in the coordination of the innate immune responses to ischemic/hypoxic acute renal tubular injury. The renoprotective effect of PACAP in AKI involves both MyD88-dependent and -independent pathways. Copyright (C) 2010 S. Karger AG, Basel

AB Whether genetic factors account for differences in early kidney disease among blacks in a young healthy population is not well known. We evaluated the association of self-reported race and genetic African ancestry with elevated creatinine (>= 1.3 mg/dl for men, >= 1.1 mg/dl for women) among 3,113 black and white participants in the Coronary Artery Risk Development in Young Adults (CARDIA) study, ages 38-50 years. We estimated individual African ancestry using 42 ancestry informative markers. Blacks were more likely to have elevated creatinine than whites, and this effect was more pronounced in men: adjusted odds ratio (AOR) for black versus white men = 7.03, 4.15-11.91; AOR for women = 2.40, 1.15-5.02. Higher African ancestry was independently associated with elevated creatinine among black men (AOR = 1.53,1.08-2.16 per SD increase in African ancestry), but not women. A graded increase in odds of elevated creatinine by African Ancestry was observed among black men compared with white men: AOR = 4.27 (2.26-10.06) for black men with 40-70% African ancestry; AOR = 8.09 (4.19-15.61) for black men with 70-80% African ancestry; AOR = 9.05 (4.81-17.02) for black men with >80% African ancestry. Genetic factors common to African ancestry may be associated with increased risk of early kidney dysfunction in a young, healthy population, particularly among black men. Copyright (C) 2009 S.

AB BACKGROUND AND PURPOSE: Region-of-interest (ROI) and tract-based diffusion tensor imaging (DTI) analyses have detected increased apparent diffusion coefficients (ADCs) and decreased fractional anisotropy (FA) in callosal and projection systems of adult patients with multiple sclerosis (MS). We explored whether similar changes occur in pediatric patients with MS, assessing 3 major white matter pathways (interhemispheric, projection, and intrahemispheric) in both visibly involved and normal-appearing white matter (NAWM).
MATERIALS AND METHODS: DTI datasets from 10 patients with established pediatric MS and 10 age-sex-, and imaging technique-matched controls were analyzed. Tracts were reconstructed by using a fiber assignment by continuous tracking algorithm with a diffusion-weighted imaging mask and a 35 degrees angular threshold. Tracts were selected by using standard ROI placements on color FA maps cross-referenced to b = 0 T2-weighted images for studying white matter pathways. Ten identical ROIs were placed in NAWM on b = 0 T2-weighted images to ensure that both ROIs and resulting tracts passed through NAWM.
RESULTS: In pediatric MS, all tracts had higher mean ADC values (P = .002 to P < .04) and lower mean FA(P = .009 to P < .02) than those in healthy controls. Even when the tracts were confined to NAWM, the mean ADC was higher (P < .004 to P < .05) and the mean FA was lower (P = .002 to P < .02). T2 lesion burden correlated with tract-based mean ADC. ROI mean ADC increased, and both tract and 1901 mean FA decreased with increasing T2 lesion burden, however with a statistically nonsignificant correlation.
CONCLUSIONS: Increased mean ADC and decreased mean FA occur in all 3 major white matter pathways, both in visibly involved white matter and NAWM in pediatric MS.

TI Intratarsal Keratinous Cysts of the Meibomian Gland: Distinctive
Clinicopathologic and Immunohistochemical Features in 6 Cases

CARCINOMA; SIMPLEX; TARSUS
AB PURPOSE: To describe 6 patients representing a new entity of Meibomian g and keratinous cysts.
DESIGN: Retrospective, interventional, clinicopathologic study.
METHODS: Review of clinical histories and findings, histopathologic evaluations, and immunohistochemical studies of the cysts' linings with monoclonal antibodies directed against cytokeratins and cell surface epithelial markers.
RESULTS: Six patients with an average age of 62.5 years had noninflamed, upper eyelid nodules fixed to the tarsus. Eyelid eversion revealed a white-yellow nodular bulge in 3 cases, a bluish coloration in 2 cases, and a translucent appearance in 1 case. The cysts were lined by undulating squamous epithelium possessing an inner eosinophilic cuticle that produced a peculiar refractile, strand,like intracavitary keratin. Immunostaining for cytokeratin 17 and carcinoembryonic antigen showed strongly positive results in the Meibomian gland cysts and, by comparison, negative results in cutaneous epidermal cysts. Multiple recurrences occurred after incomplete excisions.
CONCLUSIONS: After chalazia and sebaceous cell tumors, Meibomian gland keratinous cysts seem to be the third most common primary intratarsal lesion. Anterior fixation to the tarsus and posterior protrusion beneath the palpebral conjunctiva without inflammation suggest the diagnosis. Histopathologic and immunohistochemical evaluations can distinguish unequivocally the current entity from common epidermal cysts. The optimal treatment consists of an en bloc excision of the cyst with a tarsectomy, or else wide excision with intratarsal cautery of any remnants of the cellular lining.

TI Initiation of Acquired Immunity in the Lungs of Mice Lacking Lymph Nodes

AB Recent evidence points to lung draining lymph nodes as the site that initiates the immune response in mice infected with aerosolized Mycobacterium tuberculosis. Here we expanded these studies and showed that infection of mice that lack lymph nodes with aerosolized M. tuberculosis results in a massive mononuclear cell infiltrate in the lungs within 14 days postinfection. This infiltration clearly resembles an expansion of the bronchus-associated lymphoid tissue. As expected, no bronchus-associated lymphoid tissue was observed in M. tuberculosis-infected wild-type control mice. Importantly, acquired specific immune response to M. tuberculosis antigens could be detected in lung lymphocytes harvested from mice lacking lymph nodes as early as 14 days postinfection. In addition, the bacterial burden in these mice was indistinguishable from that observed in wild-type C57BL/6 control mice. These results indicate that in the absence of lymph nodes, priming of the immune response occurs in the lung tissues after infection of mice with aerosolized M. tuberculosis and clearly illustrate the enormous plasticity of the immune system to develop resistance to foreign pathogens.

AB Mutations in the presenilin 1 (PS1) gene are the most commonly recognized cause of familial Alzheimer's disease (FAD). Besides senile plaques, neurofibrillary tangles, and neuronal loss, Alzheimer's disease (AD) is also accompanied by vascular pathology. Here we describe an age-related vascular pathology in two lines of PS1 FAD-mutant transgenic mice that mimics many features of the vascular pathology seen in AD. The pathology was especially prominent in the microvasculature whose vessels became thinned and irregular with the appearance of many abnormally looped vessels as well as string vessels. Stereologic assessments revealed a reduction of the microvasculature in the hippocampus that was accompanied by hippocampal atrophy. The vascular changes were not congophilic. Yet, despite the lack of congophilia, penetrating vessels at the cortical surface were often abnormal morphologically and microhemorrhages; sometimes occurred. Altered immunostaining of blood vessels with basement membrane-associated antigens was an early feature of the microangiopathy and was associated with thickening of the vascular basal laminae and endothelial cell alterations that were visible ultrastructurally. Interestingly, although the FAD-mutant transgene was expressed in neurons in both lines of mice, there was no detectable expression in vascular endothelial cells or glial cells. These studies thus have implications for the role of neuronal to vascular signaling in the pathogenesis of the vascular pathology associated with AD.

First published October 22, 2009; doi:10.1152/ajpgi.00324.2009.-The inflammatory response during pancreatitis regulates necrotic and apoptotic rates of parenchymal cells. Neutrophil depletion by use of anti-polymorphonuclear serum (anti-PMN) increases apoptosis in experimental pancreatitis but the mechanism has not been determined. Our study was designed to investigate signaling mechanisms in pancreatic parenchymal cells regulating death responses with neutrophil depletion. Rats were neutrophil depleted with anti-PMN treatment. Then cerulein pancreatitis was induced, followed by measurements of apoptosis signaling pathways. There was greater activation of executioner caspases-3 in the pancreas with anti-PMN treatment compared with control. There were no differences between these groups of animals in mitochondrial cytochrome c release or in activities of initiator caspase-8 and -9. However, there was greater activation of caspase-2 with anti-PMN treatment during cerulein pancreatitis. The upstream regulation of caspases-2 includes p53, which was increased; the p53 negative regulator, Mdm2, was decreased by anti-PMN treatment during cerulein pancreatitis. In vitro experiments using isolated pancreatic acinar cells a pharmacological inhibitor of Mdm2 increased caspase2/-3 activities, and an inhibitor of p53 decreased these activities during cholecystokinin-8 treatment. Furthermore, experiments using the AR42J cell line Mdm2 small interfering RNA (siRNA) increased caspase-2/-3 activities, and p53 siRNA decreased these activities during cholecystokinin-8 treatment. These results suggest that during acute pancreatitis the inflammatory response inhibits apoptosis. The mechanism of this inhibition involves caspase-2 and its upstream regulation by p53 and Mdm2. Because previous findings indicate that promotion of apoptosis decreases necrosis and severity of pancreatitis, these results suggest that strategies to inhibit Mdm2 or activate p53 will have beneficial effects for treatment of pancreatitis.

First published September 17, 2009; doi:10.1152/ajpgi.00257.2009.-Rottlerin is a polyphenolic compound derived from Mallotus philipinensis. In the present study, we show that rottlerin decreased tumor size and stimulated apoptosis in an orthotopic model of pancreatic cancer with no effect on normal tissues in vivo. Rottlerin also induced apoptosis in pancreatic cancer (PaCa) cell lines by interacting with mitochondria and stimulating cytochrome c release. Immunoprecipitation results indicated that rottlerin disrupts complexes of prosurvival Bcl-xL with Bim and Puma. Furthermore, siRNA knockdown showed that Bim and Puma are necessary for rottlerin to stimulate apoptosis. We also showed that rottlerin and Bcl-2 and Bcl-xL inhibitor BH3I-2' stimulate apoptosis through a common mechanism. They both directly interact with mitochondria, causing increased cytochrome c release and mitochondrial depolarization, and both decrease sequestration of BH3-only proteins by Bcl-xL. However, the effects of rottlerin and BH3I-2' on the complex formation between Bcl-xL and BH3-only proteins are different. BH3I-2' disrupts complexes of Bcl-xL with Bad but not with Bim or Puma, whereas rottlerin had no effect on the Bcl-xL interaction with Bad. Also BH3I-2', but not rottlerin, required Bad to stimulate apoptosis. In conclusion, our results demonstrate that rottlerin has a potent proapoptotic and antitumor activity in pancreatic cancer, which is mediated by disrupting the interaction between prosurvival Bcl-2 proteins and proapoptotic BH3-only proteins. Thus rottlerin represents a promising novel agent for pancreatic cancer treatment.

Am J Physiol Gastrointest Liver Physiol 298: G45-G56, 2010. First published November 5, 2009; doi:10.1152/ajpgi.00349.2009.-Peptide YY (PYY) antisecretory effect on intestinal epithelia is well established, whereas less is known about its actions to influence colonic motility in conscious animals. We characterized changes in basal function and stimulated colonic motor function induced by PYY-related peptides in conscious mice. PYY3-36, PYY, and neuropeptide Y (NPY) (8 nmol/kg) injected intraperitoneally inhibited fecal pellet output (FPO) per hour during novel environment stress by 90%, 63%, and 57%, respectively, whereas the Y-1-preferring agonists, [Pro(34)] PYY and [Leu(31), Pro(34)] NPY, had no effect. Corticotrophin-releasing factor 2 receptor antagonist did not alter PYY3-36 inhibitory action. PYY and PYY3-36 significantly reduced restraint-stimulated defecation, and PYY3-36 inhibited high-amplitude distal colonic contractions in restrained conscious mice for 1 h, by intraluminal pressure with the use of a microtransducer. PYY suppression of intraperitoneal 5-hydroxytryptophan induced FPO and diarrhea was blocked by the Y-2 antagonist, BIIE0246, injected intraperitoneally and mimicked by PYY3-36, but not [Leu(31), Pro(34)] NPY. PYY3-36 also inhibited bethanechol-stimulated FPO and diarrhea. PYY3-36 inhibited basal FPO during nocturnal feeding period and light phase in fasted/refed mice for 2-3 h, whereas the reduction of food intake lasted for only 1 h. PYY3-36 delayed gastric emptying after fasting-refeeding by 48% and distal colonic transit time by 104%, whereas [Leu(31), Pro(34)] NPY had no effect. In the proximal and distal colon, higher Y-2 mRNA expression was detected in the mucosa than in muscle layers, and Y-2 immunoreactivity was located in nerve terminals around myenteric neurons. These data established that PYY/PYY3-36 potently inhibits basal and stress/serotonin/cholinergic-stimulated propulsive colonic motor function in conscious mice, likely via Y-2 receptors.

First published November 4, 2009; doi:10.1152/ajpregu.00494.2009.-We examined whether growth hormone-releasing hormone (GHRH) may promote non-rapid eye movement (NREM) sleep via activation of GABAergic neurons in the preoptic area. Male Sprague-Dawley rats were implanted with EEG, EMG electrodes and a unilateral intracerebroventricular cannula. Groups of rats received injections (3 mu l icv) with gonadotropin-releasing hormone (GHRH) (0.1 nmol/100 g body wt) or equal volume of physiological saline at the onset of the dark period and were permitted spontaneous sleep for 90 min. Separate groups of rats were sleep deprived by gentle handling for 90 min, beginning at the time of GHRH or saline injection, at the onset of the dark period. Other groups of rats received intracerebroventricular octreotide (somatostatin analog OCT) injections, intracerebroventricular injection of one of two doses of competitive GHRH antagonist, or intracerebroventricular saline injection at light onset and were then permitted 90 min spontaneous sleep-waking. Rats were killed immediately after the 90-min sleep/wake monitoring period. Brain tissue was processed for immunohistochemistry for c-Fos protein and glutamic acid decarboxylase (GAD). Single c-Fos and dual Fos-GAD cell counts were determined in the median preoptic nucleus (MnPN), and in the core and the extended parts of the ventrolateral preoptic nucleus (cVLPO and exVLPO). Intracerebroventricular GHRH elicited a significant increase in NREM sleep amount. Double-labeled Fos + GAD cell counts were significantly elevated after GHRH injection in the MnPN and VLPO in both undisturbed and sleep-deprived groups. OCT and GHRH antagonist significantly decreased NREM sleep amount compared with control rats. OCT injection increased single c-Fos-labeled cell counts in the MnPN, but not in the VLPO. Double-labeled cell counts were significantly reduced after OCT and the high dose of GHRH antagonist injection in all areas examined. These findings identify GABAergic neurons in the MnPN and VLPO as potential targets of the sleep-regulatory actions of GHRH.

First published October 28, 2009; doi:10.1152/ajprenal.00248.2009.-Glomerular endothelial cells (GEC) are strategically situated within the capillary loop and adjacent to the glomerular mesangium. GEC serve as targets of metabolic, biochemical, and hemodynamic signals that regulate the glomerular microcirculation. Unequivocally, hyperglycemia, hypertension, and the local renin-angiotensin system partake in the initiation and progression of diabetic nephropathy (DN). Whether free fatty acids (FFA) and reactive oxygen species (ROS) that have been associated with the endothelial dysfunction of diabetic macrovascular disease also contribute to DN is not known. Since endothelial cells from different organs and from different species may display different phenotypes, we employed human GEC to investigate the effect of high glucose (22.5 mmol/l), FFA (800 mu mol/l), and angiotensin II (ANG II; 10(-7) mol/l) on the genesis of ROS and their effects on endothelial nitric oxide synthase (eNOS), cyclooxygenase-2 (COX-2), and the synthesis of prostaglandins (PGs). We demonstrated that high glucose but not high FFA increased the expression of a dysfunctional eNOS as well as increased ROS from NADPH oxidase (100%) and likely from uncoupled eNOS. ANG II also induced ROS from NADPH oxidase. High glucose and ANG II upregulated (100%) COX-2 via ROS and significantly increased the synthesis of prostacyclin (PGI(2)) by 300%. In contrast, FFA did not upregulate COX-2 but increased PGI(2) (500%). These novel studies are the first in human GEC that characterize the differential role of FFA, hyperglycemia, and ANG II on the genesis of ROS, COX-2, and PGs and their interplay in the early stages of hyperglcyemia.

AB Background: Secondary stroke prevention guidelines recommend antithrombotic agents such as over-the-counter aspirin, prescription antiplatelet agents, or anticoagulant agents.
Purpose: The study was designed to measure whether use of outpatient antithrombotic agents is increasing among stroke survivors.
Methods: The sample consisted of 4168 people who self-reported cerebrovascular disease and who participated in the Medical Expenditure Panel Survey, an annual representative sample of the U.S., during the years 2000-2006. Use of antithrombotic agents was calculated from face-to-face interviews about the use of aspirin and from pharmacies about the use of prescription medications. Cochran-Armitage tests were used to detect temporal trends and multivariate models to identify predictors of use of antithrombotic agents.
Results: Pooling results across the 7 years, it was found that 57% were taking aspirin, 66% were using any antiplatelet agent, and 75% were using any antithrombotic agent. After excluding people who said aspirin was unsafe, 81% were using any antithrombotic agent. During the study period, use of prescription antiplatelet agents increased (p<0.001) but there was no temporal change in use of antithrombotic agents overall. In multivariate models, being aged >65 years, male gender, non-Hispanic ethnicity, having a usual source of care, and poor or fair health status were associated with use of an antithrombotic agent (p<0.05).
Conclusions: Although a high percentage of stroke survivors appear to use an antithrombotic agent, further research should investigate whether and how to improve care among the remaining 20% of stroke survivors, particularly among younger, female, and Hispanic patients.

AB Illicit methamphetamine abuse represents a major problem in many countries worldwide, including the United States. Prolonged regular smoking or injection of methamphetamine can cause a psychosis, typically characterized by paranoid delusions and auditory hallucinations and often associated with disturbances in mood. These symptoms may persist long after methamphetamine is discontinued and may prove refractory to antipsychotic medications. The authors describe a patient who developed a typical methamphetamine psychosis that persisted despite months of abstinence from methamphetamine and weeks of treatment with antipsychotic medication but that responded promptly to electroconvulsive therapy (ECT) on two separate occasions: on initial presentation and again a year later when the patient relapsed into methamphetamine abuse and developed psychosis again. The authors review the large international literature on methamphetamine psychosis, much of which is from Japan and has not previously been summarized in English. Persistent methamphetamine psychosis has been widely reported in Japan for more than 50 years but is rarely discussed in the American literature, possibly because some such cases are misdiagnosed in the United States as primary psychotic disorders. Given the growing public health problem of methamphetamine abuse in the United States, the distinction between persistent methamphetamine psychosis and a primary psychotic disorder has grown increasingly important. Thus, American clinicians should be alert to the possibility of methamphetamine psychosis and may wish to consider ECT in refractory cases.

AB Objective: Although attention deficit hyperactivity disorder (ADHD) in adults is associated with significant morbidity and dysfunction and afflicts both sexes, relatively few imaging studies have examined female subjects and none have had sufficient power to adequately examine sex differences. The authors examined sex differences in the neural functioning of adults with ADHD during performance of a verbal working memory task.
Method: The participants were 44 adults with ADHD matched on age, sex, and estimated IQ to 49 comparison subjects. Accuracy and reaction time on an N-back task were measured to assess working memory. The blood-oxygen-level-dependent functional MRI response was used as a measure of neural activity.
Results: A group-by-sex analysis of variance showed no between-group differences in either reaction time or percent correct for the working memory task. For both sexes combined, the adults with ADHD showed less activity than comparison subjects in prefrontal regions. However, sex-by-group analyses revealed an interaction, such that male ADHD subjects showed significantly less activity in right frontal, temporal, and subcortical regions and left occipital and cerebellar regions relative to male comparison subjects, whereas female ADHD subjects showed no differences from female comparison subjects. Exploratory correlation analyses revealed negative associations between working-memory-related activation and number of hyperactive symptoms for men and number of inattentive symptoms for women.
Conclusions: Male but not female adults with ADHD showed significantly altered patterns of neural activity during a verbal working memory task. Men and women showed different associations between neural activity and ADHD symptoms.

AB Objective. We investigated relations between deployment and new-onset depression among US service members recently deployed to the wars in Iraq and Afghanistan.
Methods. We included 40219 Millennium Cohort Study participants who completed baseline and follow-up questionnaires and met inclusion criteria. Participants were identified with depression if they met the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire criteria for depression at follow-up, but not at baseline.
Results. Deployed men and women with combat exposures had the highest onset of depression, followed by those not deployed and those deployed without combat exposures. Combat-deployed men and women were at increased risk for new-onset depression compared with nondeployed men and women (men: adjusted odds ratio [AOR]=1.32; 95% confidence interval [CI]=1.13, 1.54; women: AOR=2.13; 95% CI=1.70, 2.65). Conversely, deployment without combat exposures led to decreased risk for new-onset depression compared with those who did not deploy (men: AOR=0.66; 95% CI=0.53, 0.83; women: AOR = 0.65; 95% CI = 0.47, 0.89).
Conclusions. Deployment with combat exposures is a risk factor for new-onset depression among US service members. Post-deployment screening may be beneficial for US service members exposed to combat. (Am J Public Health. 2010;100:90-99. doi:10.2105/AJPH.2008.155432)
