AB Background-microRNAs (miRs) are small noncoding RNAs that recognize and bind to mRNAs and inhibit protein translation or degrade mRNA. Studies in animal models have suggested that miRs play a translational or posttranslational regulatory role in myocardial growth, fibrosis, viability, and remodeling. However, whether specific temporal changes in miRs occur in patients during the left ventricular (LV) remodeling process that follows a myocardial infarction (post-MI) remains unknown. The current pilot study tested the hypotheses that plasma miRs could be reliably measured in post-MI patients and that there is a relationship between temporal changes in specific miRs and post-MI LV structural remodeling.
Methods and Results-LV end-diastolic volume (echocardiography) and plasma miR were measured in age-matched referent controls (CTLs, n = 12) and post-MI patients (n = 12) from day 2 through day 90 post-MI. Selected miRs (miR-1, miR-21, miR-29a, miR-133a, and miR-208) were measured using quantitative reverse transcription-polymerase chain reaction and normalized for endogenous small nuclear RNA U6. After MI, LV end-diastolic volume increased progressively compared with CTL; this was accompanied by time-dependent changes in specific miRs. For example, miR-21 initially decreased 2 days post-MI (0.3 +/- 0.1-fold versus CTL; P<0.05), increased 5 days post-MI (2 +/- 1-fold versus CTL; P<0.05), and returned to CTL values at later post-MI time points. In contrast, miR-29a increased 5 days post-MI (4 +/- 1-fold versus CTL; P<0.05) and then decreased to CTL at later time points. miR-208 increased 5 days post-MI (3 +/- 1-fold versus CTL; P<0.05) and remained elevated up to 90 days post-MI.
Conclusions-A time-dependent change in miRs occurred in post-MI patients, including an early and robust increase in miRs that has affected myocardial growth, fibrosis, and viability. Thus, serially profiling miRs in the plasma of post-MI patients may hold both mechanistic and prognostic significance. (Circ Cardiovasc Genet. 2011;4:614-619.)

AB Background-After age, sex is the most important risk factor for coronary artery disease (CAD). The mechanism through which women are protected from CAD is still largely unknown, but the observed sex difference suggests the involvement of the reproductive steroid hormone signaling system. Genetic association studies of the gene-encoding Estrogen Receptor alpha (ESR1) have shown conflicting results, although only a limited range of variation in the gene has been investigated.
Methods and Results-We exploited information made available by advanced new methods and resources in complex disease genetics to revisit the question of ESR1's role in risk of CAD. We performed a meta-analysis of 14 genome-wide association studies (CARDIoGRAM discovery analysis, N = approximate to 87 000) to search for population-wide and sex-specific associations between CAD risk and common genetic variants throughout the coding, noncoding, and flanking regions of ESR1. In addition to samples from the MIGen (N = approximate to 6000), WTCCC (N = approximate to 7400), and Framingham (N = approximate to 3700) studies, we extended this search to a larger number of common and uncommon variants by imputation into a panel of haplotypes constructed using data from the 1000 Genomes Project. Despite the widespread expression of ER alpha in vascular tissues, we found no evidence for involvement of common or low-frequency genetic variation throughout the ESR1 gene in modifying risk of CAD, either in the general population or as a function of sex.
Conclusions-We suggest that future research on the genetic basis of sex-related differences in CAD risk should initially prioritize other genes in the reproductive steroid hormone biosynthesis system. (Circ Cardiovasc Genet. 2011;4:647-654.)

AB Treatments for women with recurrent brain metastases from breast cancer are limited. In this phase II study, we administered sagopilone to patients with breast cancer and brain metastases. We observed modest activity with a central nervous system objective response rate of 13.3%; however, median PFS was disappointing. Further studies should focus on other agents to treat this challenging clinical problem.
Background: Patients with progressive metastatic breast cancer to the central nervous system (CNS) have limited treatment options. Patients and Methods: We conducted a phase II study of sagopilone, an epothilone B analogue that crosses the blood-brain barrier, in patients with breast cancer brain metastases. Women were treated with 16 mg/m(2) or 22 mg/m(2) intravenously every 21 days. The primary endpoint was CNS objective response rate (ORR). Secondary endpoints included toxicity, progression-free survival (PFS), and overall survival (OS). Using modified, high-resolution magnetic resonance angiography (MRA), we also evaluated changes in vessel tortuosity with treatment. Results: Fifteen women were enrolled; all had progressive CNS disease despite whole-brain radiotherapy. Two patients achieved a partial response (ORR, 13.3%) and remained in the study for 6 cycles. Responses were not associated with normalization of tumor-associated vessels on correlative imaging studies. Median PFS and OS were 1.4 months and 5.3 months, respectively. The most common grade 3 toxicities were lymphopenia and fatigue. Enrollment was stopped prematurely because of limited observed activity and slow accrual. Conclusions: Sagopilone was associated with modest CNS activity in patients with breast cancer; however median PFS was disappointing. Further studies should examine other potentially active agents and/or combinations for this challenging clinical problem. Clinical Breast Cancer, Vol. 11, No. 6, 376-83 (C) 2011 Elsevier Inc.

AB The identification of oncogenic alterations in subsets of patients with non-small cell lung cancer (NSCLC) is transforming clinical care. Genomic rearrangements in anaplastic lymphoma kinase (ALK) are detected in 3% to 7% of patients with NSCLC. The ALK tyrosine kinase inhibitor crizotinib has demonstrated clinical efficacy in ALK-rearranged NSCLC patients and was recently approved by the U. S. Food and Drug Administration. Crizotinib is currently under additional phase III clinical development as both initial and second-line therapy for advanced ALK-rearranged NSCLC. However, new challenges in the diagnosis and treatment of this subset of NSCLC have emerged, including the need to determine the most effective means of diagnosing ALK-rearranged NSCLC and the emergence of acquired drug resistance to crizotinib. In this review, we discuss current strategies for treatment and diagnosis, as well as the current knowledge about mechanisms of acquired resistance to crizotinib. Finally, we discuss the strategies that are underway to clinically overcome acquired drug resistance. Clin Cancer Res; 17(23); 7213-8. (C)2011 AACR.

AB Purpose: Glioblastoma (GBM) inevitably recurs despite surgery, radiation, and chemotherapy. A subpopulation of tumor cells, GBM stem cells (GSC), has been implicated in this recurrence. The chemotherapeutic agent etoposide is generally reserved for treating recurrent tumors; however, its effectiveness is limited due to acute and cumulative toxicities to normal tissues. We investigate a novel combinatorial approach of low-dose etoposide with an oncolytic HSV to enhance antitumor activity and limit drug toxicity.
Experimental Design: In vitro, human GBM cell lines and GSCs were treated with etoposide alone, oncolytic herpes simplex virus (oHSV) G47 Delta alone, or the combination. Cytotoxic interactions were analyzed using the Chou-Talalay method, and changes in caspase-dependent apoptosis and cell cycle were determined. In vivo, the most etoposide-resistant human GSC, BT74, was implanted intracranially and treated with either treatment alone or the combination. Analysis included effects on survival, therapy-associated adverse events, and histologic detection of apoptosis.
Results: GSCs varied in their sensitivity to etoposide by over 50-fold in vitro, whereas their sensitivity to G47 Delta was similar. Combining G47 Delta with low-dose etoposide was moderately synergistic in GSCs and GBM cell lines. This combination did not enhance virus replication, but significantly increased apoptosis. In vivo, the combination of a single cycle of low-dose etoposide with G47 Delta significantly extended survival of mice-bearing etoposide-insensitive intracranial human GSC-derived tumors.
Conclusions: The combination of low-dose etoposide with G47 Delta increases survival of mice-bearing intracranial human GSC-derived tumors without adverse side effects. These results establish this as a promising combination strategy to treat resistant and recurrent GBM. Clin Cancer Res; 17(23); 7383-93. (C)2011 AACR.

AB Fulvestrant is an estrogen receptor antagonist indicated for the treatment of hormone receptor-positive metastatic breast cancer (MBC) in postmenopausal women with disease progression following antiestrogen therapy. Fulvestrant has a different mechanism of action than other hormonal therapies, including aromatase inhibitors and tamoxifen. In clinical trials of postmenopausal women with MBC, fulvestrant was effective and well tolerated compared to anastrozole after failure of tamoxifen. The monthly injection regimen of fulvestrant provides nurses with an additional opportunity to improve patient adherence to hormonal therapy, reinforce patient education, and monitor side effects. Several ongoing trials will elucidate the role of fulvestrant in the treatment of MBC. Issues that are being addressed in those trials include alternative doses and schedules, efficacy and safety in other patient populations, and the development of novel treatment combinations. This article provides oncology nurses with the knowledge needed to educate patients on the use of fulvestrant, to effectively administer this medication, and to prevent and manage potential side effects.

AB Background: Studies have demonstrated that patients with diets high in omega-3 fatty acids have a lower risk of adverse cardiovascular events. C-reactive protein (CRP), a marker of inflammation, is a strong predictor of future cardiovascular events. omega-3 fatty acids have been shown to have anti-inflammatory properties. However, there is a paucity of data examining the effect of omega-3 fatty acids on CRP levels. This randomized, double-blind, placebo-controlled trial tested the hypothesis that treatment with omega-3 polyunsaturated fatty acids (n-3 PUFAs) would reduce serum high-sensitivity CRP levels. Materials & methods: Fifty three patients with elevated baseline CRP (>= 3 mg/l) were randomized to n-3 PUFA (27 patients) or placebo (26 patients). Patients with active infection, inflammatory disease, baseline CRP >= 10 mg/l or those started on HMG-CoA reductase inhibitor therapy during the study period were excluded. The primary end point was CRP level following 8 weeks of treatment. Results: After 8 weeks of treatment with the study drug, the median CRP level in the n-3 PUFA group was 3.4 mg/l compared with 4.0 mg/l in the placebo group (p = 0.36). After controlling for baseline CRP, there was a significant percentage decrease in CRP from baseline in the n-3 PUFA group (-40.3%; p = 0.009) but not in the placebo group (-16.4%; p = 0.32) Conclusion: Treatment for 8 weeks with omega-3 fatty acids resulted in a significant percentage reduction of CRP levels as compared with baseline, a finding not seen with placebo.

AB Background &aim: n-3 PUFA has been shown to decrease the risk of several components of the metabolic syndrome; however, the role of n-3 PUFA on glucose metabolism is not clear. Our aim was to systematically review the effect of n-3 PUFA on IS by conducting a meta-analysis of available RCTs.
Methods: We followed the guidelines of Cochrane's review of systematic interventions. We searched MEDLINE, EMBASE, CENTRAL and clinicaltrials.gov from the beginning of each database until October 2010. Meta-analysis was performed using a random effects model to estimate a pooled SMD and the corresponding 95% Cl.
Results: From 303 screened citations, 11 RCTs (n = 618) were eligible for inclusion in the analysis. In a pooled estimate, n-3 PUFA intervention had no effects on IS compared to placebo (SMD 0.08, 95% Cl -0.11-0.28). Similarly, n-3 PUFA had no effects on IS in sub-group analyses (Type 2 diabetes vs. other population; QUICKI and other test subgroups). In the HOMA subgroup, n-3 PUFA was associated with a statistically significant increase in IS (SMD 0.30, Cl 0.03-0.58) when compared to placebo.
Conclusion: This meta-analysis is consistent with a lack of n-3 PUFA effects on IS. (C) 2011 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.

AB A young woman with Westphal variant (juvenile) Huntington disease (HD) also developed catatonia. Catatonia is an underdiagnosed psychomotor syndrome often associated with neurological and psychiatric disorders, but it has rarely been documented in patients with HD. Catatonia usually responds to standard treatment with benzodiazepines and electroconvulsive therapy; however, this patient's catatonic syndrome did not improve until we augmented the standard treatment with amantadine and levodopa. The underlying pathophysiology and a neurochemical hypothesis of HD and catatonia can explain their comorbidity and the refractoriness of catatonia to treatment. Both conditions are linked to dysregulation of neurotransmitters in the striatocortical and corticocortical pathways. This understanding may serve as a guide for the use of nonstandard treatments. Our evidence also suggests that electroconvulsive therapy can be useful and safe in the treatment of HD.

AB BACKGROUND Surgical-site infections (SSIs) are an unfortunate consequence of cutaneous surgery. Their incidence can be a significant problem for patients and surgeons. Most SSIs are presumed to originate from the patient and operating room staff. OBJECTIVES To review the potential routes of iatrogenic bacterial transfer during cutaneous surgery. METHODS A review of the medical literature. CONCLUSIONS Potential routes of bacterial transfer during surgery include respiratory droplets and nuclei, skin scales carried on air currents, direct contact with the surgical team's skin, and contaminated fomites. The route with the most significant potential for iatrogenic bacterial transfer is direct physical contact. Strategies that minimize contact with infected fomites and with the surgical team would probably have the best chances of reducing the incidence of SSIs.

AB Aim: To examine longitudinal differences in multiple cardiovascular risk factor control (glycemia, blood pressure, and lipids) by race/ethnicity.
Methods: Data were analyzed on a cohort of 11,203 veterans with type 2 diabetes. Primary outcome was odds of none of the risk factors out of control vs. having at least one out of control (HbA1c > 8.0%, BP > 140/90 mmHg, and LDL > 100 mg/dL). Secondary outcome was odds of having none out of control vs. having one, two or three risk factors out of control, respectively. Generalized linear mixed models assessed the relationship between race/ethnicity and multiple risk factor control adjusted for covariates.
Results: Adjusted models for primary outcome showed that NHB had two-fold (95% CI 1.8-2.3) and Hispanics had 48% higher (95% CI 1.3-1.7) odds of multiple risk factors out of control over time compared to NHW. Adjusted models for secondary outcome showed that NHB and Hispanics also had higher odds of having one, two, and three risk factors out of control over time compared to NHW.
Conclusions: Ethnic minority veterans with diabetes are less likely to have multiple cardiovascular risk factor control over time compared to whites. Thus, greater risk reduction efforts are needed to reduce the heavier disease burden among ethnic minorities. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

AB Dual competition framework (DCF) posits that low-level threat may facilitate behavioral performance by influencing executive control functions. Anxiety is thought to strengthen this effect by enhancing threat's affective significance. To test these ideas directly, we examined the effects of low-level threat and experimentally induced anxiety on one executive control function, the efficiency of response inhibition. In Study 1, briefly presented stimuli that were mildly threatening (i.e., fearful faces) relative to nonthreatening (i.e., neutral faces) led to facilitated executive control efficiency during experimentally induced anxiety. No such effect was observed during an equally arousing, experimentally induced happy mood state. In Study 2, we assessed the effects of low-level threat, experimentally induced anxiety, and individual differences in trait anxiety on executive control efficiency. Consistent with Study 1, fearful relative to neutral faces led to facilitated executive control efficiency during experimentally induced anxiety. No such effect was observed during an experimentally induced neutral mood state. Moreover, individual differences in trait anxiety did not moderate the effects of threat and anxiety on executive control efficiency. The findings are partially consistent with the predictions of DCF in that low-level threat improved executive control, at least during a state of anxiety.

AB The concept of using an immunoisolation device to facilitate the transplantation of islets without the need for immunosuppression has been around for more than 50 yr. Significant progress has been made in developing suitable materials that satisfy the need for biocompatibility, durability, and permselectivity. However, the search is ongoing for a device that allows sufficient oxygen transfer while maintaining a barrier to immune cells and preventing rejection of the transplanted tissue. Separating the islets from the rich blood supply in the native pancreas takes its toll. The immunoisolated islets commonly suffer from hypoxia and necrosis, which in turn triggers a host immune response. Efforts have been made to improve the supply of nutrients by using proangiogenic factors to augment the development of a vascular supply in the transplant site, by using small islet cell aggregates to reduce the barrier to diffusion of oxygen, or by creating scaffolds that are in close proximity to a vascular network such as the omental blood supply. Even if these efforts are successful, the shortage of donor islet tissue available for transplantation remains a major problem. To this end, a search for a renewable source of insulin-producing cells is ongoing; whether these will come from adult or embryonic stem cells or xenogeneic sources remains to be seen. Herein we will review the above issues and chart the progress made with various immunoisolation devices in small and large animal models and the small number of clinical trials carried out to date.

AB The Second International Workshop on Advances in Electrocorticography (ECoG) was convened in San Diego, CA, USA, on November 11-12, 2010. Between this meeting and the inaugural 2009 event, a much clearer picture has been emerging of cortical ECoG physiology and its relationship to local field potentials and single-cell recordings. Innovations in material engineering are advancing the goal of a stable long-term recording interface. Continued evolution of ECoG-driven brain-computer interface technology is determining innovation in neuroprosthetics. Improvements in instrumentation and statistical methodologies continue to elucidate ECoG correlates of normal human function as well as the ictal state. This proceedings document summarizes the current status of this rapidly evolving field. (C) 2011 Elsevier Inc. All rights reserved.

TI An algorithm for seizure onset detection using intracranial EEG

DE Seizure detection; Intracranial electroencephalography; Patient specific
ID EPILEPTIC SEIZURES; PREDICTION
AB This article addresses the problem of real-time seizure detection from intracranial EEG (IEEG). One difficulty in creating an approach that can be used for many patients is the heterogeneity of seizure IEEG patterns across different patients and even within a patient. In addition, simultaneously maximizing sensitivity and minimizing latency and false detection rates has been challenging as these are competing objectives. Automated machine learning systems provide a mechanism for dealing with these hurdles. Here we present and evaluate an algorithm for real-time seizure onset detection from IEEG using a machine-learning approach that permits a patient-specific solution. We extract temporal and spectral features across all intracranial EEG channels. A pattern recognition component is trained using these feature vectors and tested against unseen continuous data from the same patient. When tested on more than 875 hours of IEEG data from 10 patients, the algorithm detected 97% of 67 test seizures of several types with a median detection delay of 5 seconds and a median false alarm rate of 0.6 false alarms per 24-hour period. The sensitivity was 100% for 8 of 10 patients. These results indicate that a sensitive, specific, and relatively short-latency detection system based on machine learning can be employed for seizure detection from EEG using a full set of intracranial electrodes to individual patients.

AB Efforts to develop algorithms that can robustly detect the cessation of seizure activity within scalp EEGs are now underway. Such algorithms can facilitate novel clinical applications such as the estimation of a seizure's duration: the delivery of therapies designed to mitigate postictal period symptoms: or detection of the presence of status epilepticus. In this article, we present and evaluate a novel, machine learning-based method for detecting the termination of electrographic seizure activity. When tested on 133 seizures from a public database, our method successfully detected the end of 132 seizures within 10.3 +/- 5.5 seconds of the time determined by an electroencephalographer to represent the electrographic end of seizure. Furthermore, by pairing our seizure end detector with a previously published seizure onset detector, we could automatically estimate the duration of 85% of test electrographic seizures within a 15-second error margin compared with electroencephalographer determinations.

AB Fast ripples are high-frequency, 250-600 Hz field potential oscillations which can be recorded from hippocampal or neocortical structures. In the neocortex, fast ripples occur during both sensory information processing and under pathological, epileptic conditions. In the hippocampus and entorhinal cortex, fast ripples are exclusively associated with epilepsy and perhaps even mark the epileptogenic focus. In contrast to ripples, which regularly also occur in normal tissue and which are thought to reflect population spike bursts at 100-200 Hz paced and synchronised by recurrent inhibition, the fast ripple frequency range exceeds the maximal firing frequency of most neurones. Hence, particularly in the hippocampus, fast ripples must emerge as a network phenomenon and cannot reflect the activity of single spiking neurones. In this review, current views on the mechanisms and processes underlying fast ripples are discussed. (C) 2011 Elsevier B.V. All rights reserved.

HYPOXIA-ISCHEMIA; KAINATE; REORGANIZATION
AB The concept of a preictal state is based on the belief that it may be possible to predict seizures before they occur. The preictal state is viewed as a time period when a seizure is practically inevitable, or at least a period of greatly increased seizure probability. Changes in seizure frequency may provide insight into how seizure probability increases after brain injury. Here, time-dependent changes in the frequency of spontaneous recurrent seizures after brain injury are summarized from published, nearly continuous, electrographic (EEG) recordings of kainate-treated rats and neonatal rats subjected to hypoxia-ischemia. For these animal models, seizure frequency and thus seizure probability was a sigmoid function of time after the brain injury. This observation differs from the traditional view, where the development of epilepsy after brain injury is a step-function of time, and the latent period is the time between a brain injury and the first spontaneous seizure. Based on backward extrapolation of the plots of seizure frequency versus time, these data suggest that seizure probability increases continuously during the latent period. Also, spontaneous recurrent seizures frequently occurred in clusters, suggesting that the intra-cluster seizure intervals are periods of high seizure probability. Thus, seizure probability progressively increases as a function of time after an epileptogenic brain injury, and is particularly high between seizures within a cluster, as compared to the time between clusters. These data suggest that the detectors of the preictal state need to be accurate (and tested) over a very wide range of seizure probabilities, and that studies on the physiological events that occur during seizure clusters may provide insight on the properties of the preictal state.

AB Candida albicans frequently infects medical devices by growing as a biofilm, i.e., a community of adherent organisms entrenched in an extracellular matrix. During biofilm growth, Candida spp. acquire the ability to resist high concentrations of antifungal drugs. One recently recognized biofilm resistance mechanism involves drug sequestration by matrix beta-1,3 glucan. Using a candidate gene approach, we investigated potential C. albicans beta-1,3-glucan regulators, based on their homology to Saccharomyces cerevisiae, including SMI1 and protein kinase C (PKC) pathway components. We identified a role for the SMI1 in biofilm matrix glucan production and development of the associated drug resistance phenotype. This pathway appears to act through transcription factor Rlmp and glucan synthase Fks1p. The phenotypes of these mutant biofilms mimicked those of the smi1 Delta/smi1 Delta biofilm, and overexpression of FKS1 in the smi1 Delta/smi1 Delta mutant restored the biofilm resistant phenotype. However, control of this pathway is distinct from that of the upstream PKC pathway because the pkc1 Delta/pkc1 Delta, bck1 Delta/bck1 Delta, mkk2 Delta/mkk2 Delta, and mkc1 Delta/mkc1 Delta biofilms retained the resistant phenotype of the parent strain. In addition, resistance to cell-perturbing agents and gene expression data do not support a significant role for the cell wall integrity pathway during the biofilm formation. Here we show that Smi1p functions in conjunction with Rlm1p and Fks1p to produce drug-sequestering biofilm beta-glucan. Our work provides new insight into how the C. albicans biofilm matrix production and drug resistance pathways intersect with the planktonic cell wall integrity pathway. This novel connection helps explain how pathogens in a multicellular biofilm community are protected from anti-infective therapy.

AB Purpose: This study assessed the efficacy and safety of linifanib in patients with advanced renal cell carcinoma (RCC) who were previously treated with sunitinib.
Materials and methods: This open-label, multicentre, phase 2 trial of oral linifanib 0.25 mg/kg/day enrolled patients who had prior nephrectomy and adequate organ function. The primary end-point was objective response rate (ORR) per response evaluation criteria in solid tumors (RECIST) by central imaging. Secondary end-points were progression-free survival (PFS), overall survival (OS) and time to progression (TTP). Safety was also assessed.
Results: Fifty-three patients, median age 61 years (range 40-80) were enrolled (August 2007 to October 2008) across 12 North-American centres. Median number of prior therapies was 2 (range 1-4); 43 patients (81%) had clear-cell histology. ORR was 13.2%, median PFS was 5.4 months (95% Confidence Interval (Cl): 3.6, 6.0) and TIP was the same; median OS was 14.5 months (95% CI: 10.8, 24.1). The most common treatment-related adverse events (AEs) were diarrhoea (74%), fatigue (74%) and hypertension (66%), and the most common treatment-related Grade 3/4 AE was hypertension (40%).
Conclusions: Linifanib demonstrated clinically meaningful activity in patients with advanced RCC after sunitinib failure. At 0.25 mg/kg/day, significant dose modifications were required. An alternative, fixed-dosing strategy is being evaluated in other trials. (C) 2011 Elsevier Ltd. All rights reserved.

TI Role of CXCR4 internalization in the anti-HIV activity of stromal
cell-derived factor-1 alpha probed by a novel synthetically and
modularly modified-chemokine analog

AB The natural ligands of two major human immunodeficiency virus type 1 (HIV-1) co-receptors, CXCR4 and CCR5, can profoundly inhibit the replication of HIV-1 that uses these co-receptors for entry into the target cells. It has been postulated that these natural chemokines inhibit HIV-1 infection by blocking common binding sites on CXCR4 or CCR5 that are required for HIV-1 envelope glycoprotein gp120 interaction with its co-receptor and/or by inducing receptor internalization. To investigate whether receptor internalization caused by stromal cell-derived factor (SDF)-1 alpha, a natural ligand of CXCR4, plays a role in its anti-HIV activity, we applied the SMM (synthetically and modularly modified)chemokine approach to generate a functional probe of SDF-1 alpha that retains significant CXCR4 binding but does not induce CXCR4 internalization. The antiviral study of this functional probe analog versus wild-type SDF-1 alpha showed that, despite the significant CXCR4 binding activity, this probe analog displayed a complete loss of effect in causing CXCR4 internalization and greatly diminished antiviral activity. Interestingly, this new analog also showed a decreased number of overlapping binding sites with HIV-1 on CXCR4 transmembrane and extracellular domains. The correlation of the decrease in the anti-HIV activity with the loss of CXCR4 internalization observed with this probe molecule suggests that receptor internalization may play an important role in the anti-HIV activity of SDF-1 alpha and possibly other natural chemokines. This further implies that any modifications in SDF-1a that result in a reduction or loss of internalization activity may result in analogs that are not suitable as effective HIV-1 inhibitors that target CXCR4, unless such modifications also result in improved CXCR4 interaction with increased number of overlapping binding sites with HIV-1, thus leading to more effective steric hindrance against HIV-1.

AB Presenilin 1 (PS1) is a component of the gamma-secretase complex that cleaves a variety of type I membrane proteins, including the beta-amyloid precursor protein (beta-APP), Notch, and neuronal (N)- and epithelial (E)-cadherins. N-cadherin is an essential adhesion molecule that forms a complex with, and is cleaved by, PS1/gamma-secretase and beta-catenin in the plasma membrane. The purpose of this study was to determine whether calsenilin, a presenilin-interacting protein, has a functional role in PS1/gamma-secretase-mediated N-cadherin epsilon-cleavage using Western blot analysis, RT-PCR, immunoprecipitation, subcellular fractionation, biotinylation, and a luciferase reporter assay in SH-SY5Y neuroblastoma cells. Here, we demonstrate that the expression of calsenilin leads to a disruption of PS1/gamma-secretase-mediated epsilon-cleavage of N-cadherin, which results in the significant accumulation of N-cadherin C-terminal fragment 1 (Ncad/CTF1), the reduction of cytoplasmic Ncad/CTF2 release, and a deceleration of PS1-CTF delivery to the cell surface. Interestingly, we also found that the expression of calsenilin is associated with the redistribution of beta-catenin from the cell surface to a cytoplasmic pool, as well as with the negative regulation of genes that are targets of T-cell factor/beta-catenin nuclear signaling. Taken together, our findings suggest that calsenilin is a novel negative regulator of N-cadherin processing that plays an important role in beta-catenin signaling.-Jang, C., Choi, J.-K., Na, Y.-J., Jang, B., Wasco, W., Buxbaum, J.

AB Disc1 is a schizophrenia risk gene that engages multiple signaling pathways during neurogenesis and brain development. Using the zebrafish as a tool, we analyze the function of zebrafish Disc1 (zDisc1) at the earliest stages of brain and body development. We define a "tool" as a biological system that gives insight into mechanisms underlying a human disorder, although the system does not phenocopy the disorder. A zDisc1 peptide binds to GSK3 beta, and zDisc1 directs early brain development and neurogenesis, by promoting beta-catenin-mediated Wnt signaling and inhibiting GSK3 beta activity. zDisc1 loss-of-function embryos additionally display a convergence and extension phenotype, demonstrated by abnormal movement of dorsolateral cells during gastrulation, through changes in gene expression, and later through formation of abnormal, U-shaped muscle segments, and a truncated tail. These phenotypes are caused by alterations in the noncanonical Wnt pathway, via Daam and Rho signaling. The convergence and extension phenotype can be rescued by a dominant negative GSK3 beta construct, suggesting that zDisc1 inhibits GSK3 beta activity during noncanonical Wnt signaling. This is the first demonstration that Disc1 modulates the noncanonical Wnt pathway and suggests a previously unconsidered mechanism by which Disc1 may contribute to the etiology of neuropsychiatric disorders.-De Rienzo, G., Bishop, J.

AB Members of the fungal genus Fusarium are capable of manifesting in a multitude of clinical infections, most commonly in immunocompromised patients. In order to better understand the interaction between the fungus and host, we have developed the larvae of the greater wax moth, Galleria mellonella, as a heterologous host for fusaria. When conidia are injected into the haemocoel of this Lepidopteran system, both clinical and environmental isolates of the fungus are able to kill the larvae at 37 degrees C, although killing occurs more rapidly when incubated at 30 degrees C. This killing was dependent on several other factors besides temperature, including the Fusarium strain, the number of conidia injected, and the conidia. morphology, where macroconidia are more virulent than their microconidia counterpart. There was a correlation in the killing rate of Fusarium spp. when evaluated in G. mellonella and a murine model. In vivo studies indicated G. mellonella haemocytes were capable of initially phagocytosing both conidial morphologies. The G. mellonella system was also used to evaluate antifungal agents, and amphotericin B was able to confer a significant increase in survival to Fusarium-infected larvae. The G. mellonella Fusarium pathogenicity system revealed that virulence of Fusarium spp. is similar, regardless of the origin of the isolate, and that mammalian endothermy is a major deterrent for Fusarium infection and therefore provides a suitable alternative to mammalian models to investigate the interaction between the host and this increasingly important fungal pathogen.

AB Adeno-associated virus (AAV)-mediated gene replacement for lysosomal disorders have been spurred by the ability of some serotypes to efficiently transduce neurons in the brain and by the ability of lysosomal enzymes to cross-correct among cells. Here, we explored enzyme replacement therapy in a knock-out mouse model of congenital neuronal ceroid lipofuscinosis (NCL), the most severe of the NCLs in humans. The missing protease in this disorder, cathepsin D (CathD) has high levels in the central nervous system. This enzyme has the potential advantage for assessing experimental therapy in that it can be imaged using a near-infrared fluorescence (NIRF) probe activated by CathD. Injections of an AAV2/rh8 vector-encoding mouse CathD (mCathD) into both cerebral ventricles and peritoneum of newborn knock-out mice resulted in a significant increase in lifespan. Successful delivery of active CathD by the AAV2/rh8-mCathD vector was verified by NIRF imaging of mouse embryonic fibroblasts from knock-out mice in culture, as well as by ex vivo NIRF imaging of the brain and liver after gene transfer.

AB Ten-eleven translocation 1-3 (Tet1-3) proteins have recently been discovered in mammalian cells to be members of a family of DNA hydroxylases that possess enzymatic activity toward the methyl mark on the 5-position of cytosine (5-methylcytosine [5mC]), a well-characterized epigenetic modification that has essential roles in regulating gene expression and maintaining cellular identity. Tet proteins can convert 5mC into 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (5caC) through three consecutive oxidation reactions. These modified bases may represent new epigenetic states in genomic DNA or intermediates in the process of DNA demethylation. Emerging biochemical, genetic, and functional evidence suggests that Tet proteins are crucial for diverse biological processes, including zygotic epigenetic reprogramming, pluripotent stem cell differentiation, hematopoiesis, and development of leukemia. Insights into how Tet proteins contribute to dynamic changes in DNA methylation and gene expression will greatly enhance our understanding of epigenetic regulation of normal development and human diseases.

AB Background
Controversy persists regarding the role of Notch signaling in myelopoiesis. We have used genetic approaches, employing two Notch zebrafish mutants deadly seven (DES) and beamter (BEA) with disrupted function of notch1a and deltaC, respectively, and Notch1a morphants to analyze the development of leukocyte populations in embryonic and mature fish.
Design and Methods
Myelomonocytes were quantified in early embryos by in situ hybridization using a myeloper-oxidase (mpx) probe. Morpholinos were used to knock down expression of Notch1a or DeltaC. Wound healing assays and/or flow cytometry were used to quantify myelomonocytes in 5-day post-fertilization (dpf) Notch mutants (BEA and DES), morphants or pu.1:GFP, mpx:GFP and fms:RFP transgenic embryos. Flow cytometry was performed on 2-3 month old mutant fish.
Results
The number of mpx(+) cells in embryos was reduced at 48 hpf (but not at 26 hpf) in DES compared to WT. At 5 dpf this was reflected by a reduction in the number of myelomonocytic cells found at the wound site in mutants and in Notch1a morphants. This was due to a reduced number of myelomonocytes developing rather than a deficit in the migratory ability since transient inhibition of Notch signaling using DAPT had no effect. The early deficit in myelopoiesis was maintained into later life, 2-3 month old BEA and DES fish having a decreased proportion of myelomonocytes in both the hematopoietic organ (kidney marrow) and the periphery (coelomic cavity).
Conclusions
Our results indicate that defects in Notch signaling affect definitive hematopoiesis, altering myelopoiesis from the early stages of development into the adult.

TI Interaural comparison of spiral ganglion cell counts in profound
deafness
SO HEARING RESEARCH
LA English
DT Article
ID COCHLEAR IMPLANTATION; CHARGE SYNDROME; HISTOPATHOLOGY
AB Objectives: This study is designed to measure the degree to which spiral ganglion cell (SGC) survival in the left and right ears is similar in profoundly hearing-impaired human patients with symmetric (right/left) etiology and sensitivity. This is of interest because a small difference between ears would imply that one ear could be used as a control ear in temporal bone studies evaluating the impact on SGC survival of a medical intervention in the other ear.
Materials and methods: Forty-two temporal bones from 21 individuals with bilaterally symmetric profound hearing impairment were studied. Both ears in each individual were impaired by the same etiology. Rosenthal's canal was reconstructed in two dimensions and segmental and total SGCs were counted. Correlation analysis and t-tests were used to compare segmental and total counts of left and right ears. Statistical power calculations illustrate how the results can be used to estimate the effect size (right/left difference in SGC count) that can be reliably identified as a function of sample size.
Results: Left counts (segmental and total) were significantly correlated with those in the right ears (p < 0.01) and the coefficients of determination for segments 1 to 4 and total count were respectively 0.64, 0.91, 0.93, 0.91 and 0.98. The hypothesis that mean segmental and total counts of right and left are the same could not be rejected by paired t-test.
Conclusion: The variance in the between-ear difference across the temporal bones studied indicates that useful effect sizes can be reliably identified using subject numbers that are practical for temporal bone studies. For instance, there is 95% likelihood that an interaural difference in SGC count of approximately 1000 cells associated with a treatment/manipulation of one ear will be reliably detected in a bilaterally-symmetric profound hearing loss population of temporal bones from approximately 10 subjects.

AB Historically, acute leukemias that do not fit neatly into the broad categories of "acute myeloid leukemia" or "acute lymphoblastic leukemia" have caused considerable confusion and frustration for clinicians and pathologists. These misfit cases include bilineage and biphenotypic leukemias (collectively termed "mixed phenotype acute leukemias" in the 2008 World Health Organization Classification of Tumors of Hematopoietic and Lymphoid Tissues), as well as acute undifferentiated leukemias and other miscellaneous atypical cases. In this review, the author discusses the definitions, history, clinical behavior, and current treatment approaches to acute leukemias of Sambiguous lineage.

AB Aims: To compare the genomic signatures of wildtype (WT) and mutated GISTs and the murine interstitial cells of Cajal (ICCs) to find markers of cell differentiation and other functions that may identify cells that give rise to WT tumours.
Methods and results: We analysed the gene expression profiles of a total of 30 tumour samples (four WT GISTs and 26 mutated GISTs), selected the genes most differentially expressed (P < 0.001: 448 probe sets) and validated these results by quantitative polymerase chain reaction (PCR) and immunohistochemistry. In addition, we conducted a meta-analysis merging data from human GISTs with a genomic data set from murine ICCs. The gene expression profiles of WT and mutated GISTs differed profoundly, especially in the expression of those genes restricted primarily to neural tissues. We found that mature ICCs are more similar to mutated GISTs than WT GISTs.
Conclusions: WT GISTs have different genomic profiles from both mutated GISTs and murine mature ICCs. Considering that IGF1R expression is common to both WT GISTs and putative precursor ICCs, this study suggests that WT GISTs may derive either from ICCs at a different step of differentiation or from a different cell of origin.

AB Functional magnetic resonance imaging (fMRI) holds significant potential to aid in the development of early interventions to improve memory function, and to assess longitudinal change in memory systems in aging and early Alzheimer's disease (AD). However, the test-retest reliability of hippocampal activation and of "beneficial" deactivation in the precuneus has yet to be fully established during memory encoding tasks in older subjects. Using a mixed block and event-related face-name associative encoding paradigm, we assessed the reliability of hippocampal activation and default network deactivation over a 4- to 6-week interscan interval in 27 older individuals who were cognitively normal [Clinical Dementia Rating (CDR) Scale = 0; n = 18] or mildly impaired (CDR = 0.5; n = 9). Reliability was assessed in whole brain maps and regions of interest using both a full-task paradigm of six functional runs as well as an abbreviated paradigm of the first two functional runs, which would be advantageous for use in clinical trials. We found reliable hippocampal signal response across both block-and event-related designs in the right hippocampus. Comparable reliability in hippocampal activation was found in the full and the abbreviated paradigm. Similar reliability in hippocampal activation was observed across both CDR groups overall, but the CDR 0.5 group was more variable in left hippocampal activity. Task-related deactivation in the precuneus demonstrated much greater variability than hippocampal activation in all analyses. Overall, these results are encouraging for the utility of fMRI in "Proof of Concept" clinical trials investigating the efficacy of potentially therapeutic agents for treatment of age-related memory changes, cognitive impairment, and early AD.

AB Mucin 1 (MUC1) is a heterodimeric protein that is aberrantly overexpressed in diverse human carcinomas and certain hematologic malignancies. The transmembrane MUC1-C subunit confers tumorigenicity and is a target for anti-cancer drug development. In this regard, the MUC1-C cytoplasmic domain interacts with multiple effectors that have been linked to transformation. Here we report on the generation of a mouse monoclonal antibody (MAb) against the human MUC1-C cytoplasmic domain (MUC1-CD). This IgG1 MAb, designated anti-MUC1-CD, reacts with the NYGQLDIFP epitope. We show that anti-MUC1-CD is useful in immunoblotting and immunoprecipitation experiments. In addition, anti-MUC1-CD can be used to detect expression of the MUC1-C subunit in formalin-fixed, paraffin-embedded tissues. The MUC1-C inhibitor has entered Phase I evaluation for patients with refractory solid tumors. The present results indicate that the anti-MUC1-CD antibody could be useful as a biomarker to identify patients with tumors that may be responsive to MUC1-C inhibitors.

AB Humoral molecules can trigger injury on mechanically stressed and damaged tissue. We have studied the role of complement 3 (C3) in a mouse model of ventilator-induced lung injury (VILI). Compared with shamtreated wild type (WT) mice, ventilated WT mice have reduced total bronchoalveolar lavage (BAL) cells; and elevated activities of thrombin and matrix metalloproteinases (MMPs), such as gelatinase/collagenase in the BAL fluid. In contrast, these parameters in ventilated C3 null mice are not significantly different from sham-treated WT and C3 null mice. In mechanically ventilated mice, thrombin activity and MMPs are lower in 0 null mice than in WT mice and are inversely correlated with total single BAL cells. C3 activation is associated with MMP activation in vitro. Pretreatment of WT mice with humanized cobra venom factor, which inactivates C3, reduces 0 deposition in the lung and increases total BAL cells in VILI We propose that C3 is involved with VILI and inhibition of complement activation may be a potential therapeutic strategy.

AB Body dysmorphic disorder (BDD) is characterized by perceived defects in one's physical appearance (e.g., facial asymmetry). Cognitive-behavioral models of BDD suggest that several factors, including negative appearance-related beliefs and life experiences, such as teasing, might be related to BDD's unique symptomatology Research on perceived teasing in BDD is still limited, and the relationships previously found have been based on small sample sizes. In the current study, we investigated perceived appearance-related teasing in the German population (total N = 2,510; BDD group: n = 45; age and gender-matched non-BDD group: n = 45). As expected, the BDD group reported significantly more teasing than did the non-BDD group (40.0% vs 15.6%). Whereas no group difference was obtained regarding the years of age at the first teasing incident, the BDD group remembered the teasing experience more vividly (p =.008) and as more traumatic (p =.002). This study provides further evidence for perceived teasing in BDD.

AB Theoretical and empirical rationale support cognitive behavioral therapy (CBT) as the psychological treatment of choice for body dysmorphic disorder (BDD). The aim of this article is to review the evidence from published outcome studies of cognitive, behavioral, and cognitive-behavioral interventions for BDD. The literature on CBT for BDD is sparse but promising. Evidence suggests that CBT for BDD is associated with symptom improvement, generally performs better than wait-list controls, and is associated with improvement in associated features, including functioning, depression, anxiety, and delusional beliefs. However, the small number of studies and methodological limitations hamper definitive conclusions about the efficacy of CBT for BDD. We propose directions for future research.

AB Individuals with body dysmorphic disorder (BDD) have distressing or impairing preoccupations with imagined or slight defects in their appearance (e.g., nose too big). BDD is a severe psychiatric disorder often associated with high rates of suicidality as well as social and occupational impairment (Phillips, Coles, Menard, Yen, Fay, & Weisberg, 2005). Researchers have only recently begun to investigate psychological treatments for BDD, with available data suggesting that cognitive behavioral therapy (CBT) appears efficacious for BDD (Williams, Hadjistavropoulos, & Sharpe, 2006). To our knowledge there are no reports of whether CBT for BDD can be effectively generalized to ethnic minority and other special populations. We suggest specific modifications within the CBT for BDD framework that might improve the effectiveness and retention rates of CBT among ethnic minority patients with BDD. Specifically, the cases of Ben, a 40-year-old, Jewish, married male, and John, a 30-year-old, African American, single male, both with a primary diagnosis of BDD, are described. Various treatment techniques were used the course of CBT more culturally responsive. This case report illustrates the challenges and benefits of integrating cultural variables into a CBT framework for BDD, and it highlights the need for more work in this area.

AB Both the 17-item Hamilton Rating Scale for Depression (HRSD(17)) and 30-item Inventory of Depressive Symptomatology - Clinician-rated (IDS-C(30)) contain a subscale that assesses anxious symptoms. We used classical test theory and item response theory methods to assess and compare the psychometric properties of the two anxiety subscales (HRSD(ANX) and IDS-C(ANX)) in a large sample (N = 3453) of outpatients with non-psychotic major depressive disorder in the Sequenced Treatment Alternatives to Relieve Depression (STAR(star)D) study. Approximately 48% of evaluable participants had at least one concurrent anxiety disorder by the self-report Psychiatric Diagnostic Screening Questionnaire (PDSQ). The HRSD(ANX) and IDS-C(ANX) were highly correlated (r = 0.75) and both had moderate internal consistency given their limited number of items (HRSD(ANX) Cronbach's alpha = 0.48; IDS-C(ANX) Cronbach's alpha = 0.58). The optimal threshold for ascribing the presence/absence of anxious features was found at a total score of eight or nine for the HRSD(ANX) and seven or eight for the IDS-C(ANX). It would seem beneficial to delete item 17 (loss of insight) from the HRSD(ANX) as it negatively correlated with the scale's total score. Both the HRSD(ANX) and IDS-C(ANX) subscales have acceptable psychometric properties and can be used to identify anxious features for clinical or research purposes.

AB PURPOSE. This study compared susceptibility of Fuchs endothelial corneal dystrophy (FECD) and normal corneal endothelial cells (CECs) to oxidative stress, and studied the mechanism of oxidative-stress-induced apoptosis in FECD-affected endothelium.
METHODS. For in vitro studies, immortalized normal and FECD human corneal endothelial cell lines (HCECi and FECDi, respectively) were exposed to tert-butyl hydroperoxide (tBHP). Apoptotic cell populations were distinguished using flow cytometry. Reactive oxygen species production was measured by a horseradish peroxidase assay. For ex vivo studies, CECs were exposed to tBHP. Oxidative DNA damage and apoptosis were assessed by anti-8-hydroxydeoxyguanosine antibody and TUNEL assay, respectively. p53 and phospho-p53 levels were assessed by Western blot and immunohistochemistry.
RESULTS. Flow cytometry revealed a higher rate of apoptosis in FECDi than that in HCECi after exposure to 0.5 mM (P = 0.010) and 1.0 mM tBHP (P = 0.041). Further analysis showed increased production of H(2)O(2) by FECDi than that by HCECi. Oxidative DNA damage increased in both normal and FECD CECs after exposure to 0.5 mM tBHP (P = 0.031 and 0.022, respectively), leading to a 21% increase in TUNEL-positive CECs in FECD (P = 0.015) but no change in normal. Baseline p53 expression was twofold higher in FECD than that in normal endothelium (P = 0.002). Immunofluorescence revealed an increase in p53 and phospho-p53 levels in FECD compared with that in normal endothelium.
CONCLUSIONS. FECD CECs are more susceptible to oxidative DNA damage and oxidative-stress-induced apoptosis than normal. Increased activation of p53 in FECD suggests that it mediates cell death in susceptible CECs. The authors conclude that p53 plays a critical role in complex mechanisms regulating oxidative-stress-induced apoptosis in FECD.

AB PURPOSE. Suturing amniotic membrane to cornea during surgery is time consuming, and sutures may further damage the eye. The authors introduce a novel sutureless, light-activated technique that securely attaches amnion to cornea through protein-protein crosslinks.
METHODS. Cryopreserved human amniotic membrane, stained with Rose Bengal (RB), was placed over a full-thickness wound in deepithelialized rabbit cornea and was treated with green laser. The intraocular pressure that broke the seal (IOP(L)) was measured, and adhesion was measured with a peel test. The influences on bonding strength of fluence, irradiance, RB concentration, and amnion surface bonded were measured. Epithelial cell migration on treated amnion and keratocyte viability after bonding were also measured. The involvement in the bonding mechanism of oxygen, singlet oxygen, and association of RB with stromal collagen was investigated.
RESULTS. Sealing amniotic membrane over cornea using 0.1% RB and 150 J/cm(2) at 532 nm produced an IOP L of 261 +/- 77 mm Hg ex vivo and 448 mm +/- 212 mm Hg in vivo. The ex vivo IOP L increased with increasing fluence (50-150 J/cm(2)). Equivalent IOP L was produced for bonding basement membrane or stromal amnion surfaces. The bonding treatment was not toxic to keratocytes but slightly reduced the migration of corneal epithelial cells on amnion ex vivo. Mechanism studies indicated that RB forms two complexes with amnion stromal collagen, that bonding requires oxygen, and that singlet oxygen mediates protein crosslinking.
CONCLUSIONS. A rapid, light-activated technique produces strong, immediate bonding between amnion and cornea and merits further evaluation for ocular surface surgeries. (Invest Ophthalmol Vis Sci. 2011;52:9470-9477) DOI:10.1167/iovs.11-7248

AB PURPOSE. To determine the biocompatibility of a new wireless intraocular pressure (IOP) transducer (WIT) in rabbit eyes and to correlate its measurements with other pressure-measuring devices.
METHODS. The WIT is a ring-shaped intraocular device that allows wireless IOP measurements through radiofrequency. It was implanted into six eyes of New Zealand White rabbits after extracapsular lens extraction. A sham rabbit eye with no transducer implanted was used as a control. The animals were observed and examined by microscopy at various intervals up to 25 months after surgery. IOP was measured at various intervals by pneumotonometry, tonometry, WIT, and manometry. The data from the various devices were compared and analyzed for reproducibility. Two eyes were enucleated at 5.5 and 20 months after implantation and analyzed by histology.
RESULTS. The WIT appears to be well tolerated in the rabbit eye, with no evidence of significant inflammation or scar formation by microscopic in vivo examination. Histology did not reveal intraocular inflammation or membrane formation. Repeated IOP measurements with pneumotonometry, tonometry, and the WIT resulted in SDs of 2.70 mm Hg, 3.35 mm Hg, and 0.81 mm Hg, respectively. The concordance between the WIT and direct manometry measurements was high. A downward drift in IOP measured by the WIT was noted in three rabbits, necessitating recalibration.
CONCLUSIONS. The WIT is well tolerated by the rabbit eye. Its measurements are reproducible and in close concordance with manometry. A downward IOP drift warrants further investigation. (Invest Ophthalmol Vis Sci. 2011; 52:9573-9580) DOI: 10.1167/iovs.11-7878

AB Background Epidemiological studies evaluating the association between folate intake and risk of pancreatic cancer have produced inconsistent results. The statistical power to examine this association has been limited in previous studies partly because of small sample size and limited range of folate intake in some studies.
Methods We analyzed primary data from 14 prospective cohort studies that included 319 716 men and 542 948 women to assess the association between folate intake and risk of pancreatic cancer. Folate intake was assessed through a validated food-frequency questionnaire at baseline in each study. Study-specific relative risks (RRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models and then pooled using a random effects model. All statistical tests were two-sided.
Results During 7-20 years of follow-up across studies, 2195 pancreatic cancers were identified. No association was observed between folate intake and risk of pancreatic cancer in men and women (highest vs lowest quintile: dietary folate intake, pooled multivariable RR = 1.06, 95% CI = 0.90 to 1.25, P-trend = .47; total folate intake [dietary folate and supplemental folic acid], pooled multivariable RR = 0.96, 95% CI = 0.80 to 1.16, P-trend = .90). No between-study heterogeneity was observed (for dietary folate, P-heterogeneity = .15; for total folate, P-heterogeneity = .22).
Conclusion Folate intake was not associated with overall risk of pancreatic cancer in this large pooled analysis.

AB PURPOSE To describe new findings in a case of unilateral retinal dysplasia.
METHODS Histopathologic evaluation of an enucleated globe and analysis with immunohistochemical probes, karyotyping, and genetic analysis for the Norrie gene, and aqueous assay for vascular endothelial growth factor A (VEGF-A).
RESULTS Histopathological examination of the globe revealed retinal dysplasia with pseudorosette formation, abnormal or absent retinal nuclear lamination, a paucity of disorganized retinal microvasculature, retinal infoldings, advanced gliosis, persistent hyperplastic vitreous, exuberant neovascularization of the vitreous, and iris neovascularization (identical to the findings observed in bilateral Norrie disease). Immunohistochemistry disclosed GFAP-positive and GLUT-1-positive gliosis and retinal and persistent hyperplastic vitreous microvessels that were CD34-positive and GLUT-1-negative. Ki-67-positive retinal cells were polarized toward the subretinal space and absent in the retinal invaginations and pseudorosettes. A normal karyotype was found, and DNA sequencing revealed no known mutation in the region of the Norrie gene (NDP) in sputum or retinal DNA. Aqueous obtained immediately after enucleation contained an exceptionally high concentration of VEGF-A (4.5 ng/mL).
CONCLUSIONS Despite the failure to find an abnormal ND P allele, other unexplored NDP regions, an undetected defect restricted to retinal tissues, or an autosomal mutation coupled with disrupted signaling pathways may be responsible for the condition. High aqueous VEGF-A suggests that this cytokine may play a role in pathogenesis in conjunction with other pathways. (J AAPOS 2011;15:579-586)

negative modulator of ciliogenesis, in patients with chronic
rhinosinusitis

AB Background: Sinonasal mucosa in patients with chronic rhinosinusitis (CRS) is often devoid of motile cilia. This defect is presumed to result from prolonged inflammation, infection, or both. However, the mechanism underlying this observation is unknown. Recently, centrosomal protein 110 (Cp110) was shown to prevent the terminal step in ciliary maturation (ie, elongation), suggesting that Cp110 might be involved in pathological states in which ciliation is abnormal.
Objectives: First, we sought to investigate the expression of Cp110 in sinonasal mucosa from patients with CRS and control subjects. Second, we sought to determine the extent that inflammatory cytokines modulate Cp110 expression and ciliary maturation in vitro.
Methods: Sinonasal mucosal specimens from patients with and without CRS were analyzed for Cp110 mRNA and protein expression. Furthermore, human and murine nasal respiratory epithelial cultures were used to investigate Cp110 expression under normal growth conditions and in the presence of exogenous proinflammatory cytokines.
Results: Increased Cp110 mRNA and protein expression was found in sinonasal mucosal specimens from patients with CRS compared with that seen in control specimens. During ciliogenesis in vitro, the expression of Cp110 gradually decreased in cultures derived from patients without CRS but remained increased in cultures derived from patients with CRS. Furthermore, cultures grown in the presence of proinflammatory cytokines demonstrated increased levels of Cp110 expression with concomitant inhibition of ciliogenesis.
Conclusion: Increased Cp110 expression in mucosa from patients with CRS might contribute to the poor ciliation observed in patients with CRS. Exogenous cytokine exposure maintains increased levels of Cp110 expression. Regulation of Cp110 expression by inflammation warrants additional investigation because it might offer a novel target in the management of respiratory tract diseases.

AB We examined the association between different types of prayer and depressive symptoms-with rumination and social support as potential mediators-in a sample of predominantly White, Christian, and female ambulatory cancer patients. In a cross-sectional design, 179 adult cancer outpatients completed measures of prayer, rumination, social support, depressive symptoms, and demographic variables. Type and stage of cancer were collected from electronic medical charts. Depressive symptoms were negatively correlated with adoration prayer (r = -.15), reception prayer (r = -.17), thanksgiving prayer (r = -.29), and prayer for the well-being of others (r = -.26). In the path analysis, rumination fully mediated the link between thanksgiving prayer and depressive symptoms (beta for indirect effect = -.05), whereas social support partially mediated the link between prayer for others and depressive symptoms (beta for indirect effect = -.05). These findings suggest that unique mechanisms may link different prayer types to lower depressive symptoms among cancer patients.

AB Background: Increased vasopressin levels may be present in patient with chronic heart failure (HF) and contribute to pathophysiology through effects on the vasopressin V2 receptor. The presence of background diuretic therapy may confound evaluations of vasopressin receptor antagonists (VRA).
Methods and Results: Eligible patients had FIF (New York Heart Association Class 11411), systolic dysfunction (left ventricular ejection fraction <= 0.40) and signs of congestion (eg, edema, rales). At screening, patients were removed from baseline diuretic therapy and placed on a low-sodium diet (2 g/day). After a 2-day run-in period, 83 patients were randomized to placebo (n = 21), monotherapy with the vasopressin V2 receptor antagonist tolvaptan (TLV) 30 mg (n = 20), monotherapy with furosernide 80 mg (FURO, n = 22) or both TLV 30 mg and FURO 80 mg (n = 20) once daily for 7 days. Patients were on standard background therapy and not fluid-restricted throughout the study. A decrease in body weight of -1.37 +/- 1.61, -0.54 +/- 1.59, and -1.13 +/- 1.49 kg was observed versus baseline for TLV, FURO, and TLV+FURO, respectively, at day 8. At the same point, the placebo group showed a body weight increase of +0.72 +/- 2.42 kg versus baseline (P = .0006 for TLV versus placebo). Increases in urine volume from baseline were greater with TLV alone (2646 +/- 1503 mL/24 hours) than with FURO (894 +/- 853 mL/24 hours, P < .001), or PLC (423 +/- 786 mL/24 hours, P < .001), and similar to TLV+FURO (2585 2119 mL/24 hours). An increase in serum sodium within the normal range was also observed in TLV-treated patients (P < .02 versus placebo; P < .01 versus FURO). No changes in serum potassium, other laboratory values, or blood pressure were observed. TLV therapy was well tolerated.
Conclusions: In patients with HF and signs of volume overload, TLV monotherapy without concomitant loop diuretic therapy reduced body weight when compared to placebo without adverse changes in serum electrolytes, during a sodium restricted diet while on background medications including angiotensin-converting enzyme inhibitors and beta-blockers.

AB Background: Activated vitamin D analog, paricalcitol, has been shown to attenuate the development of cardiac hypertrophy in Dahl salt sensitive (DSS) rats. To determine whether an antihypertrophic effect is class specific, we tested if doxercalciferol (a pro-hormone vitamin D2 analog) could also attenuate the development of cardiac hypertrophy in DSS rats.
Methods and Results: Male DSS rats were fed a high salt (HS) diet for 6 weeks beginning at 6 weeks of age. Doxercalciferol was administered intraperitoneally at 150 ng, 3 times per week (Monday, Wednesday, Friday) for 6 weeks. Pathological and echocardiographic findings demonstrated that rats on HS diet with doxercalciferol administration had significant decrease in cardiac hypertrophy and improved cardiac function compared to the HS + vehicle. In addition, there was a significant decrease in plasma brain natriuretic peptide (BNP) level and tissue atrial natriuretic factor (ANF) mRNA level with doxercalciferol treatment. Doxercalciferol also significantly reduced the level of protein kinase C-alpha (PKC alpha) suggesting that PKC-mediated cardiac hypertrophy may be associated with vitamin D deficiency.
Conclusions: Administration of doxercalciferol attenuated the development of HS diet induced cardiac hypertrophy and cardiac dysfunction in DSS rats. (J Cardiac Fail 2011;17:1051-1058)

AB Study Objectives: To determine whether the first-attempt tracheal intubation incidence using the GlideScope videolaryngoscope is higher in patients with predicted increased risk of difficult laryngoscopy, and to assess the ability of other a priori defined standard risk factors to predict first-attempt intubation success, in aggregate and by forming scores.
Design: Prospective study.
Setting: Operating room in a tertiary-care academic center.
Patients: 357 patients intubated with the GlideScope for nonernergent general anesthesia.
Interventions and Measurements: Mallampati airway class was used to create two groups of patients, one with higher and the other, lower, potential difficult laryngoscopy (Mallampati classes 3-4 and 1-2, respectively). Intubation success on the first attempt with the GlideScope videolaryngoscope in patients with a Mallampati class 3 or 4 airway versus those with Mallampati class 1 or 2 airway was tested. We also evaluated the predictive ability of the Mallampati airway class (1 and 2 vs 3 and 4) along with 9 other possible predictors of difficult intubation on first-attempt intubation success: gender, age, body mass index, level of training within our anesthesia residency program (Clinical Anesthesia Resident years 1, 2, and 3), ASA physical status, mouth opening, thyromental distance, neck flexion, and neck extension.
Main Results: None of the standard predictors of difficult intubation was significantly associated with outcome after adjusting for other predictors. A multivariable model containing the aggregate set of variables predicted outcome significantly better than a risk score formed as the sum of 10 predictors ("Risk 10"; P = 0.0176).
Conclusions: With GlideScope-assisted tracheal intubation, Mallampati airway class is not an independent risk factor for difficult intubation. Other standard clinical risk factors of difficulty with direct laryngoscopy also do not appear to be individually predictive of first-attempt success of tracheal intubation. (C) 2011 Elsevier Inc.

PATHWAY; STREPTOZOCIN; DOXORUBICIN; FLUOROURACIL; EFFICACY
AB Context: Everolimus, an oral inhibitor of mammalian target of rapamycin, significantly prolongs progression-free survival (PFS) in patients with advanced pancreatic neuroendocrine tumors (pNET). Chromogranin A (CgA) and neuron-specific enolase (NSE) are considered general biomarkers of these tumors.
Objective: The objective of the study was to evaluate the prognostic value of CgA and NSE in patients with pNET treated with everolimus.
Patients and Methods: Patients with low-to intermediate-grade advanced pNET enrolled in two phase 2 studies [RAD001 in Advanced Neuroendocrine Tumors (RADIANT-1) and single institution phase II study at The University of Texas M. D. Anderson Cancer Center] received everolimus. Blood samples were collected and analyzed by a central laboratory at baseline and monthly thereafter. PFS and overall survival (OS) were evaluated in patients with elevated and nonelevated baseline CgA/NSE levels. Results: In RADIANT-1, elevated vs. nonelevated baseline CgA was associated with shorter median PFS (8.34 vs. 15.64 months; P = 0.03) and OS (16.95 months vs. not reached; P < 0.001). Elevated vs. nonelevated baseline NSE resulted in shorter median PFS (7.75 vs. 12.29 months; P = 0.01) and OS (13.96 vs. 24.90 months; P = 0.005). Median PFS was prolonged in patients with early CgA or NSE response (11.0 vs. 5.0 months) compared with those without early biomarker response. More patients with CgA (87 vs. 50%) or NSE (81 vs. 14%) response experienced tumor shrinkage compared with those without response. CgA response data from the single-institution phase II study at The University of Texas M. D. Anderson Cancer Center study are consistent with data from the RADIANT-1 study.
Conclusions: Elevated baseline CgA/NSE provided prognostic information on PFS and survival; early CgA/NSE responses are potential prognostic markers for treatment outcomes in patients with advanced pNET. (J Clin Endocrinol Metab 96: 3741-3749, 2011)

DIABETES-MELLITUS; INDUCED APOPTOSIS; SKELETAL-MUSCLE; GENE-EXPRESSION
AB Context: Islet beta-cells express both insulin receptors and insulin signaling proteins. Recent studies suggest insulin signaling is physiologically important for glucose sensing.
Objective: Preexposure to insulin enhances glucose-stimulated insulin secretion (GSIS) in healthy humans. We evaluated whether the effect of insulin to potentiate GSIS is modulated through regulation of free fatty acids (FFA).
Design and Setting: Subjects were studied on three occasions in this single-site study at an academic institution clinical research center.
Patients: Subjects included nine healthy volunteers.
Interventions: Glucose-induced insulin response was assessed on three occasions after 4 h saline (low insulin/sham) or isoglycemic-hyperinsulinemic (high insulin) clamps with or without intralipid and heparin infusion, using B28 Asp-insulin that could be distinguished from endogenous insulin immunologically. During the last 80 min of all three clamps, additional glucose was administered to stimulate insulin secretion (GSIS) with glucose concentrations maintained at similar concentrations during all studies.
Main Outcome Measure: beta-Cell response to glucose stimulation was assessed.
Results: Preexposure to exogenous insulin increased the endogenous insulin-secretory response to glucose by 32% compared with sham clamp (P = 0.001). This was accompanied by a drop in FFA during hyperinsulinemic clamp compared with the sham clamp (0.06 +/- 0.02 vs. 0.60 +/- 0.09 mEq/liter, respectively), which was prevented during the hyperinsulinemic clamp with intralipid/heparin infusion (1.27 +/- 0.17 mEq/liter). After preexposure to insulin with intralipid/heparin infusion to maintain FFA concentration, GSIS was 21% higher compared with sham clamp (P < 0.04) and similar to preexposure to insulin without intralipid/heparin (P = 0.2).
Conclusions: Insulin potentiates glucose-stimulated insulin response independent of FFA concentrations in healthy humans. (J Clin Endocrinol Metab 96: 3811-3821, 2011)

AB Context: Black South African women are less insulin sensitive than their White counterparts, despite less central and greater peripheral fat deposition. We hypothesized that this paradox may be explained, in part, by differences in the adipogenic capacity of sc adipose tissue (SAT).
Objective: Our objective was to measure adipogenic and lipogenic gene expression in abdominal and gluteal SAT depots and determine their relationships with insulin sensitivity (S(I)) in South African women.
Participants and Design: Fourteen normal-weight [body mass index (BMI) <25 kg/m(2)] Black, 13 normal-weight White, 14 obese (BMI >30 kg/m(2)) Black, and 13 obese White premenopausal South African women participated in this cross-sectional study.
Main outcomes: S(I) (frequently sampled iv glucose tolerance test) in relation to expression of adipogenic and lipogenic genes in abdominal and gluteal SAT depots.
Results: With increasing BMI, Black women had less visceral fat (P = 0.03) and more abdominal (P = 0.017) and gynoid (P = 0.041) SAT but had lower S(I) (P < 0.01) than White women. The expression of adipogenic and lipogenic genes was proportionately lower with obesity in Black but not White women in the gluteal and deep SAT depots (P < 0.05 for ethnicity x BMI effect). In Black women only, the expression of these genes correlated positively with S(I) (all P < 0.05), independently of age and fat mass.
Conclusions: Obese Black women have reduced SAT expression of adipogenic and lipogenic genes compared with White women, which associates with reduced S(I). These findings suggest that obesity in Black women impairs SAT adipogenesis and storage, potentially leading to insulin resistance and increased risk of type 2 diabetes.

TI Circulating Adiponectin Is Inversely Associated with Risk of Thyroid
Cancer: In Vivo and in Vitro Studies

AB Context: Circulating adiponectin has been inversely associated with risk for several malignancies. Its association with thyroid cancer has not yet been evaluated.
Objective/Methods: We measured circulating adiponectin levels in 175 thyroid carcinoma patients and 107 controls. We also examined the expression of adiponectin receptors (AdipoR1 and AdipoR2) using immunohistochemistry in 82 thyroid carcinoma tissues and using RT-qPCR in 40 human thyroid carcinoma tissues (32 papillary, six follicular/Hurthle, one anaplastic, one medullary), four normal human thyroid tissue specimens, and the BHP7 and SW579 thyroid cancer cell lines. We then utilized these thyroid cancer cell lines to investigate whether adiponectin could directly regulate cell cycle or apoptosis.
Results: Thyroid cancer patients had lower circulating adiponectin levels than controls (17.00 +/- 6.32 vs. 19.26 +/- 6.28 +/- mu g/ml; P < 0.001). Subjects in the highest tertile of circulating adiponectin concentrations had significantly lower odds of developing any type of thyroid carcinoma (odds ratio = 0.29; 95% confidence interval, 0.16-0.55), or papillary thyroid carcinoma (odds ratio = 0.27; 95% confidence interval, 0.14-0.55), before and after adjustment for potential confounders. Both thyroid carcinoma cell lines and tissues expressed AdipoR1 and AdipoR2. Recombinant adiponectin did not exert a clinically significant direct effect on cell cycle, proliferation, or apoptosis in thyroid cancer cell lines in vitro.
Conclusions: Circulating adiponectin is independently and inversely associated with the risk of thyroid cancer. Human thyroid carcinomas and cell lines express adiponectin receptors. However, in the absence of a major direct effect of adiponectin on thyroid cancer cell lines in vitro, the negative association observed herein may be attributed to the metabolic effects of adiponectin.

TI Change in Undercarboxylated Osteocalcin Is Associated with Changes in
Body Weight, Fat Mass, and Adiponectin: Parathyroid Hormone (1-84) or
Alendronate Therapy in Postmenopausal Women with Osteoporosis (the PaTH
Study)
SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM

DT Article
ID VITAMIN-K STATUS; SERUM OSTEOCALCIN; PLASMA-GLUCOSE; METABOLISM;
PROTEIN; MEN
AB Context: The undercarboxylated form of the osteoblast-secreted protein osteocalcin has favorable effects on fat and glucose metabolism in mice. In human subjects, cross-sectional studies suggest a relevant association.
Objective: We investigated whether changes in undercarboxylated osteocalcin (ucOC) during osteoporosis treatment are associated with changes in metabolic parameters.
Design, Setting, Participants, and Interventions: We measured ucOC in sera from a subset of osteoporotic postmenopausal women who were treated with PTH(1-84) or alendronate (n = 64 and n = 33, respectively) during the Parathyroid Hormone and Alendronate study.
Main Outcome Measures: We measured serum adiponectin, leptin, and insulin and analyzed existing data on body weight, fat mass, and serum glucose concentration. Three-month changes in ucOC levels were evaluated as predictors of 12-month changes in indices of fat and glucose metabolism.
Results: ucOC levels increased with PTH(1-84) and decreased with alendronate administration (P <= 0.01 for both treatment groups). Three-month change in ucOC was inversely associated with 12-month changes in body weight (standardized beta = -0.25, P = 0.04) and fat mass (beta = -0.23, P = 0.06), after adjustment for the treatment group. Three-month change in ucOC was positively associated with a 12-month change in adiponectin (beta = 0.30, P = 0.01), independent of change in fat mass. There were no interactions between treatment and change in ucOC on changes in weight, fat mass, or adiponectin.
Conclusions: PTH(1-84) increases and alendronate decreases ucOC levels. Changes in ucOC induced by PTH(1-84) and alendronate are associated with changes in metabolic indices. These associations are consistent with observations from animal models and support a role for ucOC in the skeletal regulation of energy metabolism in humans.

AB BACKGROUND: A case of homozygous familial lecithin:cholesterol acyltransferase (LCAT) deficiency with a novel homozygous LCAT missense mutation (replacement of methionine by arginine at position 293 in the amino acid sequence of the LCAT protein) is reported. METHODS AND
RESULTS: The probable diagnosis was suggested by findings of marked high density lipoprotein (HDL) deficiency, corneal opacification, anemia, and renal insufficiency. The diagnosis was confirmed by two dimensional gel electrophoresis of HDL, the measurement of free and esterified cholesterol, and sequencing of the LCAT gene.
CONCLUSIONS: In our view the most important aspects of therapy to prevent the kidney disease that these patients develop is careful control of blood pressure and lifestyle measures to optimize non HDL lipoproteins. In the future replacement therapy by gene transfer or other methods may become available. (C) 2011 Published by Elsevier Inc. on behalf of National Lipid Association.

AB Neurosurgical procedures involving the skull base and structures within can pose a significant risk of damage to the brain stem and cranial nerves. This can have life-threatening consequences and/or result in devastating neurologic deficits. Over the past decade, intraoperative neurophysiology has significantly evolved and currently offers a great tool for live monitoring of the integrity of nervous structures. Thus, dysfunction can be identified early and prompt modification of the surgical management or operating conditions, leads to avoidance of permanent structural damage. Along these lines, the vestibulocochlear nerve (CN VIII) and, to a greater extent, the auditory pathways as they pass through the brain stem are especially at risk during cerebelopontine angle (CPA), posterior/middle fossa, or brain stem surgery. CN VIII can be damaged by several mechanisms, from vascular compromise to mechanical injury by stretch, compression, dissection, and heat injury. Additionally, cochlea itself can be significantly damaged during temporal bone drilling, by noise, mechanical destruction, or infarction, and because of rupture, occlusion, or vasospasm of the internal auditory artery. CN VIII monitoring can be successfully achieved by live recording of the function of one of its parts, the cochlear or auditory nerve (AN), using the brain stem auditory evoked potentials (BAEPs), electrocochleography (ECochG), and compound nerve action potentials (CNAPs) of the cochlear nerve. This is a review of these techniques, their principle, applications, methodology, interpretation of the evoked responses, and their change from baseline, within the context of surgical and anesthesia environments, and finally the appropriate management of these changes.

AB Purpose
Women with germline BRCA1 and BRCA2 mutations have five- to 20-fold increased risks of developing breast and ovarian cancer. A recent study claimed that women testing negative for their family-specific BRCA1 or BRCA2 mutation (noncarriers) have a five-fold increased risk of breast cancer. We estimated breast cancer risks for noncarriers by using a population-based sample of patients with breast cancer and their female first-degree relatives (FDRs).
Patients and Methods
Patients were women with breast cancer and their FDRs enrolled in the population-based component of the Breast Cancer Family Registry; patients with breast cancer were tested for BRCA1 and BRCA2 mutations, as were FDRs of identified mutation carriers. We used segregation analysis to fit a model that accommodates familial correlation in breast cancer risk due to unobserved shared risk factors.
Results
We studied 3,047 families; 160 had BRCA1 and 132 had BRCA2 mutations. There was no evidence of increased breast cancer risk for noncarriers of identified mutations compared with FDRs from families without BRCA1 or BRCA2 mutations: relative risk was 0.39 (95% CI, 0.04 to 3.81). Residual breast cancer correlation within families was strong, suggesting substantial risk heterogeneity in women without BRCA1 or BRCA2 mutations, with some 3.4% of them accounting for roughly one third of breast cancer cases.
Conclusion
These results support the practice of advising noncarriers that they do not have any increase in breast cancer risk attributable to the family-specific BRCA1 or BRCA2 mutation. J Clin Oncol 29:4505-4509. (C) 2011 by American Society of Clinical Oncology

for Advanced-Stage Non-Small-Cell Lung Cancer
SO JOURNAL OF CLINICAL ONCOLOGY

SENSITIVITY; BREAST
AB Purpose
R1507 is a selective, fully human, recombinant monoclonal antibody (immunoglobulin G1 subclass) against insulin-like growth factor-1 receptor (IGF-1R). The strong preclinical evidence supporting coinhibition of IGF-1R and epidermal growth factor receptor (EGFR) as anticancer therapy prompted this study.
Patients and Methods
Patients with advanced-stage non-small-cell lung cancer (NSCLC) with progression following one or two prior regimens, Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2, and measurable disease were eligible. Patients were randomly assigned to receive erlotinib (150 mg orally once a day) in combination with either placebo, R1507 9 mg/kg weekly, or R1507 16 mg/kg intravenously once every 3 weeks. Treatment cycles were repeated every 3 weeks. The primary end point was comparison of the 12-week progression-free survival (PFS) rate.
Results
In all, 172 patients were enrolled: median age, 61 years; female, 33%; never-smokers, 12%; and performance status 0 or 1, 88%. The median number of R1507 doses was six for the weekly arm and 3.5 for the every-3-weeks arm. Grades 3 to 4 adverse events occurred in 37%, 44%, and 48% of patients with placebo, R1507 weekly, and R1507 every 3 weeks, respectively. The 12-week PFS rates were 39%, 37%, and 44%, and the median overall survival was 8.1, 8.1, and 12.1 months for the three groups, respectively, with statistically nonsignificant hazard ratios. The 12-week PFS rate in patients with KRAS mutation was 36% with R1507 compared with 0% with placebo.
Conclusion
The combination of R1507 with erlotinib did not provide PFS or survival advantage over erlotinib alone in an unselected group of patients with advanced NSCLC. Predictive biomarkers are essential for further development of combined inhibition of IGF-1R and EGFR. J Clin Oncol 29:4574-4580. (C) 2011 by American Society of Clinical Oncology

TI Problematic Video Game Use Scale: Initial Psychometric Properties With
Psychiatrically Hospitalized Adolescents
SO JOURNAL OF CLINICAL PSYCHIATRY

ID HOPELESSNESS SCALE; INTERNET USE; CHILDREN; ADDICTION; VALIDITY; PLAY
AB Objective: Excessive video game use among youth has been a growing concern in the United States and elsewhere. The aims of this study are to establish validity of a video game measure in a large adolescent inpatient sample, identify clinical factors underlying problem video game use, and identify associations with measures of psychopathology.
Method: Three hundred eighty participants admitted to an adolescent inpatient psychiatric unit between November 2007 and March 2009 were administered a battery of self-report measures, including a questionnaire developed for this study that assessed reinforcers and consequences of past-year video game use (ie, Problematic Video Game Use Scale). Factor analysis was used to identify the underlying structure of behaviors associated with problem video game use.
Results: A factor analysis of the Problematic Video Game Use Scale indicated 2 primary factors. One was associated with engaging in problem behaviors that impaired the adolescent's functioning as a result of playing video games and one reflected the reinforcing effects of playing video games. Both factors were associated with measures of psychopathology, although associations were generally stronger for impairment in functioning than for reinforcing effects. Both factors were significantly correlated with self-reported daily video game use (P < .001).
Conclusions:Two underlying factors emerged to account for problem video game playing: impairment in functioning and reinforcing effects. Initial evidence of the content validity of the video game measure was established. Findings highlight the importance of assessing video game use among an adolescent population, the factors associated with video game use, and associations with symptoms of psychopathology. Limitations include a common reporter for multiple measures and cross-sectional data that do not allow for causal links to be made.

DIAGNOSTIC CRITERIA
AB Objective: Late-life depression is an important public health issue, given the growing proportion of the elderly relative to the general population in the developed world. The purpose of this study was to examine the efficacy of antidepressants for the treatment of major depressive disorder (MDD) in elderly patients.
Data Sources: PubMed/MEDLINE was searched for randomized, double-blind, placebo-controlled trials of antidepressants for treatment of both adult (nonelderly) MDD (patients aged < 65 years) and late-life MDD (patients aged >= 55 years). The search was limited to articles published between January 1, 1980, and March 3, 2010 (inclusive). The year 1980 was used as a cutoff in our search to decrease diagnostic variability, since the DSM-III was introduced in 1980. Our search cross-referenced the term placebo with each of the following antidepressants: amitriptyline, nortriptyline, imipramine, desipramine, clomipramine, trimipramine, protriptyline, dothiepin, doxepin, lofepramine, amoxapine, maprotiline, amineptine, nomifensine, bupropion, phenelzine, tranylcypromine, isocarboxazid, moclobemide, brofaromine, fluoxetine, sertraline, paroxetine, citalopram, escitalopram, fluvoxamine, zimelidine, tianeptine, trazodone, nefazodone, agomelatine, venlafaxine, desvenlafaxine, duloxetine, milnacipran, reboxetine, mirtazapine, and mianserin. We also reviewed the reference lists of all studies identified through the PubMed/MEDLINE search.
Study Selection: Articles were selected that reported on randomized, double-blind, placebo-controlled trials of antidepressants used as monotherapy for treatment of MDD and that met numerous a priori criteria pertaining to MDD diagnosis criteria, study duration, study design, drug formulation, original data, age thresholds, primary and secondary outcome measures, and exclusions of other disorders. Final inclusion of articles was determined by consensus between the authors. Seventy-four articles were found eligible for inclusion in our analysis (15 late-life MDD trials and 59 adult MDD trials).
Results: Antidepressants were found to be efficacious for late-life MDD (age 55 and older; P <.0001), although there was evidence for heterogeneity across studies (Q(22)=67.302, P <.001). However, antidepressants were not found to be efficacious in the subset of studies using age thresholds of 65 years or older (older late-life MDD) (P=.265). Finally, when we controlled for study design characteristics, antidepressant but not placebo response rates were lower among late-life MDD patients than among adult MOD patients.
Conclusions: The present meta-analysis suggests that antidepressants are efficacious in late-life MDD, but significant study heterogeneity suggests that other factors may contribute to these findings. A secondary analysis raises the possibility that efficacy of these agents may be reduced in trials involving patients aged 65 years or older. Why antidepressants may be less efficacious in elderly versus younger subjects remains unclear. J Clin Psychiatry 2011;72(12):1660-1668 (C) Copyright 2011 Physicians Postgraduate Press, Inc.

AB Objective: To reanalyze data from a 2002 study by the Hypericum Depression Trial Study Group to determine whether patients who believed they were receiving active therapy rather than placebo obtained greater improvement, independent of treatment.
Method:Three hundred forty adults with major depressive disorder (according to the Structured Clinical Interview for DSM-IV) and baseline scores of >= 20 on the 17-item Hamilton Depression Rating Scale (HDRS-17) were randomized to Hypericum perforatum 900-1,500 mg/d, sertraline 50-100 mg/d, or placebo and were asked to guess their assigned treatment after 8 weeks. This reanalysis of data was performed from October 1, 2009, to April 15, 2011 The intent-to-treat sample included 207 subjects (mean age = 44 years) who had (1) at least 1 postbaseline visit; (2) adherence data based on serum levels of hyperforin, sertraline, and desmethylsertraline; and (3) guess data. Univariate factorial analysis of variance was used to determine whether treatment assignment affected clinical improvement according to HDRS-17 score and whether this effect was moderated by patient guess of sertraline, Hypericum, or placebo. Analysis of covariance was used to determine whether side effects mediated improvement in the context of patient guess and assigned treatment. chi(2) analyses compared response rates (>= 50% decrease in HDRS-17 score) between the guess groups and between the treatment groups within each guess group.
Results: Assigned treatment had no significant effect on clinical improvement (P=.65), but patient guess was significantly associated with improvement (P <.001), and treatment and guess interacted significantly (P=.005). Among subjects who guessed placebo, clinical improvement was small and did not differ significantly across treatments. Among subjects who guessed Hypericum, improvement was large and did not differ significantly across treatments. Among subjects who guessed sertraline, those who received placebo or sertraline had large improvements, but those who received Hypericum had significantly less improvement (P <.001). Similar findings were obtained for response rates.
Conclusions: Patient beliefs regarding treatment may have a stronger association with clinical outcome than the actual medication received, and the strength of this association may depend upon the particular combination of treatment guessed and treatment received.

TI Weight Suppression Predicts Time to Remission From Bulimia Nervosa
SO JOURNAL OF CONSULTING AND CLINICAL PSYCHOLOGY
LA English
DT Article
DE bulimia nervosa; weight suppression; remission; outcome
ID FOLLOW-UP; REPORTED WEIGHT; ACCURACY; RISK
AB Objective: To investigate whether, at study entry, (a) weight suppression (WS), the difference between highest past adult weight and current weight, prospectively predicts time to first full remission from bulimia nervosa (BN) over a follow-up period of 8 years, and (b) weight change over time mediates the relationship between WS and time to first full remission. Method: A well-characterized sample of women with BN (N = 110; M age = 25.58 years, SD = 6.48) from the Massachusetts General Hospital Longitudinal Study of Eating Disorders was interviewed at 6-12 month intervals over 8 years. The main outcome measure, a "time to first full remission" variable, was based on psychiatric status ratings generated from the Eating Disorders Longitudinal Interval Follow-up Evaluation. Results: WS was significantly associated with time to first full remission (p = .01; hazard ratio = .89; 95% confidence interval [0.82, 0.97]), indicating that women who were more weight suppressed at study entry took longer to recover. Weight change did not mediate the relationship between WS and time to remission. Conclusions: Results add to a growing body of evidence that WS predicts maintenance of BN symptoms and extend previous short-term findings by demonstrating, over a period of approximately 8 years, that WS predicts longer time to first full remission. Beyond absolute weight status, WS level may significantly inform the treatment of BN.

AB This issue of the Journal features collaborative follow-up studies of two unique pregnancy cohorts recruited during 1959-1966 in the United States. Here we introduce the Early Determinants of Adult Health (EDAH) study. EDAH was designed to compare health outcomes in midlife (age 40s) for same-sex siblings discordant on birthweight for gestational age. A sufficient sample of discordant siblings could only be obtained by combining these two cohorts in a single follow-up study. All of the subsequent six papers are either based upon the EDAH sample or are related to it in various ways. For example, three papers report results from studies that significantly extended the 'core' EDAH sample to address specific questions.
We first present the overall design of and rationale for the EDAH study. Then we offer a synopsis of past work with the two cohorts to provide a context for both EDAH and the related studies. Next, we describe the recruitment and assessment procedures for the core EDAH sample. This includes the process of sampling and recruitment of potential participants; a comparison of those who were assessed and not assessed based on archived data; the methods used in the adult follow-up assessment; and the characteristics at follow-up of those who were assessed. We provide online supplementary tables with much further detail. Finally, we note further work in progress on EDAH and related studies, and draw attention to the broader implications of this endeavor.

AB Major depressive disorder (MDD) and cardiovascular disease (CVD) represent leading causes of morbidity and mortality worldwide. We tested the hypothesis that growth restriction and preeclampsia (referred to as fetal risk) are significant predictors of these conditions, with women at higher risk in adulthood. Adult offspring exposed to fetal risk factors and their discordant siblings were from two prenatal cohorts, whose mothers were followed through pregnancy and whom we recruited as adults 40 years later (n = 538; 250 males and 288 females). Subjects were psychiatrically diagnosed and underwent a stress challenge during which parasympathetic regulation was assessed by electrocardiogram, operationalized as high-frequency R-R interval variability (HF-RRV). Linear mixed models and generalized estimating equations were used to examine the relationship of fetal risk on HF-RRV, MDD and comorbidity of low HF-RRV (lowest 25th percentile) and MDD, including interactions with sex and socioeconomic status (SES). Fetal risk was significantly associated with low HF-RRV response (F = 3.64, P = 0.05), particularly among low SES (interaction: F = 4.31, P < 0.04). When stratified by MDD, the fetal risk impact was three times greater among MDD compared with non-MDD subjects (effect size: 0.21 v. 0.06). Females had a significantly higher risk for the comorbidity of MDD and low HF-RRV than males (relative risk (RR) = 1.36, 95% CI: 1.07-1.73), an association only seen among those exposed to fetal risk (RR = 1.38, 95% CI: 1.04-1.83). Findings suggest that these are shared fetal antecedents to the comorbidity of MDD and CVD risk 40 years later, an association stronger in females than in males.

AB Both reductions in birth weight and preeclampsia (PE) have been associated with decrements in scores on tests of intelligence in children and adolescents. We examined whether these decrements persist into middle adulthood and expand into other domains of cognitive functioning. Using data from the Early Determinants of Adult Health project and from the ancillary project, Fetal Antecedents of Major Depression and Cardiovascular Disease, we selected term same-sex sibling sets or singletons from these sets, from the New England Family Study (NEFS) and the Child Health and Development Studies (CHDS), discordant on either fetal growth or PE, to test the hypotheses that prenatal exposure to inflammation was associated with decrements in attention, learning and executive function 40 years later. Exposure was defined as a continuous measure of percentile birth weight for gestational age, reduced fetal growth (<20th percentile of birth weight for gestational age) or maternal PE. Given that the sample was comprised, in part, of sibling sets, the analyses were performed using mixed models to account for the inter-sibling correlations. Analyses were performed separately by study site (i.e. NEFS and CHDS). We found few statistically significant associations (suggesting a possible type II error) consistent with previous literature, suggesting that the associations with low birth weight do not persist into midlife. We discuss the possible reasons for the lack of associations, which include the possible mediating effects of the postnatal environment.

AB Background: Antibiotic selection made within the first hour of recognition of severe sepsis and septic shock has been shown to decrease mortality. Objective: The purpose of this study was to determine what antibiotics are being prescribed and to identify factors influencing ineffective antibiotic coverage in patients with severe sepsis or septic shock. In addition, we explore an alternative method for antibiotic selection that could improve organism coverage. Methods: This was a retrospective review of emergency department (ED) patients admitted to an intensive care unit (ICU) over a 12-month period with a culture-positive diagnosis of either severe sepsis or septic shock. Appropriate antibiotic therapy was defined as effective coverage of the offending organism based on final culture results. Results: Of the 1400 patients admitted to the ICU, 137 patients were culture positive and met the criteria for severe sepsis or septic shock. Effective antibiotic coverage was prescribed by emergency physicians in 82% (95% confidence interval [CI] .74-.88) of cases. Of the 25 patients who received ineffective antibiotics, the majority had infections caused by resistant Gram-negative organisms. Health care-associated pneumonia guidelines were applied to all patients, regardless of the source of infection, and were 100% sensitive (95% CI .93-1) for selecting patients who had infections caused by highly resistant organisms. Conclusion: Emergency physicians achieved 82% effective antibiotic coverage in patients with severe sepsis or septic shock. The gap seems to be in coverage of highly resistant Gram-negative organisms. An alternative approach to antibiotic prescription, utilizing a set of guidelines for community- and health care-associated infections, was found to be 100% sensitive in selecting patients who had infections caused by the more resistant organisms.

TI FRAMEWORK FOR ANALYZING WAIT TIMES AND OTHER FACTORS THAT IMPACT PATIENT
SATISFACTION IN THE EMERGENCY DEPARTMENT
SO JOURNAL OF EMERGENCY MEDICINE
LA English
DT Article
DE emergency department; patient satisfaction
ID CUSTOMER SATISFACTION; MODEL; COMMUNICATION
AB Background: Wait times and patient satisfaction are important administrative metrics in emergency departments (EDs), as they are critical to return patronage, liability, and remuneration. Although several factors have been shown to impact patient satisfaction, little attention has been paid to understanding the psychology of waiting and patient satisfaction. Objective: We utilize concepts that have been applied in other service industries to conceptualize factors that impact patient satisfaction. We focus on wait times, a key factor in patient satisfaction, and describe how these concepts can be applied in research and daily practice. Discussion: Patient satisfaction can be conceptualized as the difference between a patient's perceptions and their expectations. Perception is the psychological process by which an individual understands and interprets sensory information. Changes in the wait experience can decrease the perceived wait times without a change in actual wait times. Other changes such as improved staff interpersonal and communication skills that provide patients with an increased sense of the staff's dedication as well as a greater understanding of their care, can also affect patient perceptions of their care quality. These changes in patient perception can synergize with more expensive investments such as state-of-the-art facilities and increased ED beds to magnify their impact on patient satisfaction. Expectation is the level of service a patient believes they will receive during their ED visit. Patients arrive with expectations around the component of their care such as wait times, needed diagnostic tests, and overall time in the ED. These expectations are affected by individual-specific, pre-encounter, and intra-encounter factors. When these factors are identified and understood, they can be managed during the care process to improve patient satisfaction. Conclusion: Interventions to decrease perception of wait times and increase the perception of service being provided, when combined with management of patient expectations, can improve patient satisfaction.

AB Objective. To assess the potential for genetic influences on sertraline treatment efficacy for depression of Alzheimer disease (dAD). Four functional genetic variants were studied: 2 serotonin receptors (HTR2A-T102C and HTR2C-Cys23Ser), the serotonin transporter (5HTT-LPR), and brain-derived neurotrophic factor (BDNF-Val66Met). Treatment response by genotype was measured by (1) the modified Alzheimer's Disease Cooperative Study Clinical Global Impression of Change, (2) the Cornell scale for Depression in Dementia, and (3) remission of depression. Methods. We utilized data from the Depression in Alzheimer's Disease Study 2 (DIADS-2), a 24-week, randomized, multicenter trial showing no significant treatment effect of sertraline on dAD. Proportional odds logistic regression and mixed effects models were used to examine the above mentioned outcome measures. Results. No significant interactions were seen between any of the genetic polymorphisms and the selected outcomes above at 12 or 24 weeks. Discussion. Treatment outcomes in the DIADS-2 trial were not significantly influenced by genetic variation at the loci that were assessed. Future studies should continue to examine the interaction of depression-related genetic variants with antidepressant treatment in Alzheimer disease patients with depression.

AB Objectives: Vancomycin resistant enterococcus (VRE) infective endocarditis (IE) is an increasing nosocomial problem. We describe the clinical management and outcomes of a cohort of patients with VRE IE at a tertiary endocarditis referral center.
Methods: Retrospective review of all proven cases of VRE IE, from July 2000 through January 2008 was performed. Demographics, comorbidities and therapeutic details were collected and analyzed to assess for risk factors and clinical outcomes.
Results: Fifty cases of VRE IE were identified: 26 (52%) were Enterococcus faecium and 24 were Enterococcus faecalis. Vancomycin resistant E. faecalis IE was associated with the presence of a central venous line, liver transplantation, and mitral valve infection while VR E. faecium IE was significantly associated with tricuspid valve infection (p = 0.03). The median duration of bacteremia was 14 days for E. faecium and 4 days for E. faecalis, respectively (p = 0.002). Factors associated with mortality on bivariate analysis were hemodialysis via a catheter with VR E. faecium (OR = 11.7. CI 1.1-122, p = 0.02) and liver transplantation with both species. Combination antimicrobial therapy (OR = 0.5 CI = 0.06-3.2, p = 0.1) and valve surgery (OR 1.3 CI 0.8-20, p = 0.02) trended toward improved survival with E. faecalis on bivariate analysis. On multivariate analysis, none of the associations were significant.
Conclusions: Hemodialysis and liver transplantation were factors associated with acquisition of VRE IE. There was a higher mortality and prolonged bacteremia with VR E. faecium IE than VR E. faecalis IE. Although not significant, combination antimicrobial therapy and surgical intervention trended toward improved survival. Published by Elsevier Ltd on behalf of The British Infection Association.

AB Background The increasing prevalence of human immunodeficiency virus type 1 (HIV-1) subtype C infection worldwide calls for efforts to develop a relevant animal model for evaluating AIDS candidate vaccines. In China, the prevalent HIV strains comprise a circulating recombinant form, BC (CRF07_BC), in which the envelope belongs to subtype C.
Methods To evaluate potential AIDS vaccines targeting Chinese viral strains in non-human primate models, we constructed a simian/ human immunodeficiency virus (SHIV) carrying most of the envelope sequence of a primary HIV-1 clade C strain isolated from an HIV-positive intravenous drug user from YunNan province in China. Furthermore, to determine whether in vivo adaptation would enhance the infectivity of SHIVCN97001, the parental infectious strain was serially passaged through eight Chinese rhesus macaques.
Results Infection of six Chinese rhesus macaques with SHIV-CN97001 resulted in a low level of viremia and no significant alteration in CD4+ T-lymphocyte counts. However, the hallmarks of SHIV infectivity developed gradually, as shown by the increasingly elevated peak viremia with each passage.
Conclusion These findings establish that the R5-tropic SHIV-CN97001/ Chinese rhesus macaque model should be very useful for the evaluation of HIV-1 subtype C vaccines in China.

AB Smoking and PTSD are predictors of poor physical health status. This study examined the unique contribution of PTSD symptoms in the prediction of the SF-36 physical health status subscales accounting for cigarette smoking, chronic medical conditions, alcohol and drug use disorders, and depression. This study examined baseline interview and self-report data from a national tobacco cessation randomized, controlled trial (Veterans Affairs Cooperative Study 519) that enrolled tobacco-dependent veterans with chronic PTSD (N = 943). A series of blockwise multiple regression analyses indicated that PTSD numbing and hyperarousal symptom clusters explained a significant proportion of the variance across all physical health domains except for the Physical Functioning subscale, which measures impairments in specific physical activities. Our findings further explain the impact of PTSD on health status by exploring the way PTSD symptom clusters predict self-perceptions of health, role limitations, pain, and vitality.

AB Objective: Peacekeepers, relief workers, and military members experience multiple traumas, and trauma is believed to increase risk for psychiatric distress. We examined whether combat and/or peacekeeping or relief work was associated with subsequent mental illness. Methods: Using data from the US National Co-morbidity Survey Replication (n = 2383), we estimated whether combat, peacekeeping, or relief work was associated with increased prevalence of mental illness through bivariate cross-tabulations and multivariate logistic regression. Results: Combat was associated with increased subsequent posttraumatic stress disorder (PTSD) and alcohol or drug issues more than peacekeeping or relief work. Conclusions: Combat, alone or combined with peacekeeping/relief work, appears to be a risk factor for subsequent PTSD and issues with drugs and alcohol. Peacekeeping/relief work without combat does not appear to be associated with these diagnoses. Clinical Significance: We found an association between combat and subsequent PTSD and drug and alcohol issues. Absent combat, peacekeeping, or relief work were not associated with mental illness. Previous diagnoses and trauma exposure may increase potential for subsequent mental health problems.

AB Context. The treatment of pain in patients with substance use disorders creates tensions for clinicians between undertreating pain and enabling opioid analgesic misuse.
Objectives. To characterize prevalence and factors associated with aberrant opioid analgesic behaviors in a cohort of HIV-infected individuals who are at high risk for opioid analgesic misuse.
Methods. We assessed pain and substance use disorders in a cross-sectional study that enrolled 296 participants from the Research on Access to Care in the Homeless cohort, a community-based sample of indigent HIV-infected adults. We measured aberrant opioid behaviors, defined as major or minor depending on level of risk of harm to patients, using Audio Computer-Assisted Self-Interview technology.
Results. Most participants (91.2%) reported pain in the week before interview, with the majority of these experiencing severe pain (53.7%). More than two-thirds (69.2%) of the participants met criteria for a lifetime history of cocaine, amphetamine, or heroin/opioid use disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition). More than one-third of the sample (37.4%) had a history of aberrant opioid behavior within 90 days of interview. One-fifth (18.5%) had a history of "major" aberrant behaviors.
Conclusion. In this high-risk population, severe pain is common and aberrant opioid behaviors are prevalent but not universal. As recommended by American Pain Society and American Academy of Pain Medicine guidelines, when prescribing opioid analgesics, clinicians must consider variation in the severity of aberrant behaviors, particularly aberrant behaviors that may represent undertreatment of pain.

TI Giving Voice to Patients' and Family Caregivers' Needs in Chronic Heart
Failure: Implications for Palliative Care Programs
SO JOURNAL OF PALLIATIVE MEDICINE

ID PHYSICAL IMPAIRMENT; COLLABORATIVE CARE; CHRONIC ILLNESS; DEPRESSION;
CANCER; ASSOCIATION; MANAGEMENT; STATEMENT; AMERICAN; SERVICES
AB Background: The American College of Cardiology Foundation/American Heart Association (ACC/AHA) Guidelines for the Management of Heart Failure recommend palliative care in the context of Stage D HF or at the end of life. Previous studies related to heart failure (HF) palliative care provide useful information about patients' experiences, but they do not provide concrete guidance for what palliative care needs are most important and how a palliative care program should be structured.
Objectives: Describe HF patients' and their family caregivers' major concerns and needs. Explore whether, how, and when palliative care would be useful to them.
Design and participants: Qualitative study using in-depth interviews of 33 adult outpatients with symptomatic HF identified using purposive sampling and 20 of their family caregivers.
Approach: Interviews were transcribed verbatim and analyzed using the constant comparative method.
Key results: Overall, patients and caregivers desired early support adjusting to the limitations and future course of illness, relief of a number of diverse symptoms, and the involvement of family caregivers using a team approach. A diverse group of participants desired these elements of palliative care early in illness, concurrent with their disease-specific care, coordinated by a provider who understood their heart condition and knew them well. Some diverging needs and preferences were found based on health status and age.
Conclusions: HF patients and their family caregivers supported early integration of palliative care services, particularly psychosocial support and symptom control, using a collaborative team approach. Future research should test the feasibility and effectiveness of integrating such a program into routine HF care.

TI Training Nurses for Interdisciplinary Communication with Families in the

FOLLOW-UP; END; SKILLS; PHYSICIANS; EFFICACY; MEETINGS
AB Background: Critical care nurse communication training has largely been limited to didactic materials, interactive training for nurse supervisors, or brief participatory learning programs within the context of comprehensive end-of-life care educational seminars. Preliminary evidence suggests that an interactive approach can also be effective in communication skills training for intensive care unit (ICU) nurses.
Methods: We implemented a 1-day educational intervention in five acute care hospitals within Veterans Integrated Service Network (VISN) 3 (New York-New Jersey region) of the Department of Veterans Affairs and focused solely on communication skills and targeted specifically to nurses providing bedside care for critically ill patients. A "learner centered'' approach to skills training that has several integral components was employed. Among these are: a cognitive, evidence-based foundation upon which to build new skills; a method such as role-play that allows participants to practice newly learned skills; and an affective component, during which trainees can freely discuss their impressions of the exercise or explore difficulties that may have been encountered. Before and after the program we conducted a detailed assessment of participants' self-rated communication skills and of the techniques and materials we used.
Results and conclusions: Post-program responses documented significant improvement in self-evaluated skills for each of the core tasks we assessed. Evidence suggests that communication with patients and families in the ICU can be most effectively approached in an interdisciplinary way. For nurses to fully realize their potential for optimal communication as members of the multidisciplinary team, they must be equipped with the necessary skills. We believe this new program helps to expand the range of approaches for training nurses in essential communication skills.

ID CONTROLLED-TRIAL; OF-LIFE; CONSULTATION; COST
AB This study describes emergency physicians' perspectives on the challenges and benefits to providing palliative care in an academic, urban, public hospital in Los Angeles. Participants underwent a semi-structured interview on their training and experiences related to palliative care, perceptions of providing palliative care, and their recommendations for education and training in this area. Overall, respondents felt that palliative care is not prioritized appropriately, leading patients to be unaware of their options for end-of-life care. Providing educational materials and courses that have been developed from the ED perspective should be included in ongoing continuing medical education. Having a palliative care team that is responsive to the needs of the ED will further enhance collaboration with the ED. Future research should focus on understanding the range of benefits to having palliative care in the ED.

AB Objective. Soluble CD14 (sCD14) is involved in innate immune responses and has been implicated to play a pathogenic role in inflammatory diseases including rheumatoid arthritis (RA). No studies have identified the specific factors that influence sCD14 expression in RA. We used cross-sectional data to evaluate the relationship of sCD14 concentrations in RA with measures of disease activity and severity. We hypothesized that sCD14 concentrations would be elevated in subjects with greater RA disease severity and markers of disease activity, compared to subjects with lower disease activity. We also examined whether well-defined polymorphisms in CD14 are associated with sCD14 expression in RA.
Methods. Soluble CD14 concentrations were measured using banked serum from patients with RA (n = 1270) and controls (n = 186). Associations of patient factors including demographics, measures of RA disease activity/severity, and select CD14 single-nucleotide polymorphisms (SNP) with sCD14 concentration were examined in patients with RA using ordinal logistic regression.
Results. Circulating concentrations of sCD14 were higher in patients with RA compared to controls (p < 0.0001). Factors significantly and independently associated with higher sCD14 levels in patients with RA included older age, being white (vs African American), lower body mass index, elevated high sensitivity C-reactive protein, and higher levels of disease activity based on the Disease Activity Score (DAS28). There were no significant associations of CD14 tagging SNP with sCD14 level in either univariate or multivariable analyses.
Conclusion. Circulating levels of sCD14 are increased in RA and are highest in patients with increased levels of RA disease activity. In the context of RA, sCD14 concentrations also appear to be strongly influenced by specific patient factors including older age and race but not by genetic variation in CD14.

AB The medical profession should play a central role in evaluating the evidence related to drugs, devices, and procedures for the detection, management, and prevention of disease. When properly applied, expert analysis of available data on the benefits and risks of these therapies and procedures can improve the quality of care, optimize patient outcomes, and favorably affect costs by focusing resources on the most effective strategies. An organized and directed approach to a thorough review of evidence has resulted in the production of clinical practice guidelines that assist physicians in selecting the best management strategy for an individual patient. Moreover, clinical practice guidelines can provide a foundation for other applications, such as performance measures, appropriate use criteria, and both quality improvement and clinical decision support tools.
The American College of Cardiology Foundation (ACCF) and the American Heart Association (AHA) have jointly produced guidelines in the area of cardiovascular disease since 1980. The ACCF/AHA Task Force on Practice Guidelines (Task Force), charged with developing, updating, and revising practice guidelines for cardiovascular diseases and procedures, directs and oversees this effort. Writing committees are charged with regularly reviewing and evaluating all available evidence to develop balanced, patient-centric recommendations for clinical practice.
Experts in the subject under consideration are selected by the ACCF and AHA to examine subject-specific data and write guidelines in partnership with representatives from other medical organizations and specialty groups. Writing committees are asked to perform a formal literature review; weigh the strength of evidence for or against particular tests, treatments, or procedures; and include estimates of expected outcomes where such data exist. Patient-specific modifiers, comorbidities, and issues of patient preference that may influence the choice of tests or therapies are considered. When available, information from studies on cost is considered, but data on efficacy and outcomes constitute the primary basis for the recommendations contained herein.
In analyzing the data and developing recommendations and supporting text, the writing committee uses evidence-based methodologies developed by the Task Force (1). The Class of Recommendation (COR) is an estimate of the size of the treatment effect considering risks versus benefits in addition to evidence and/or agreement that a given treatment or procedure is or is not useful/effective or in some situations may cause harm. The Level of Evidence (LOE) is an estimate of the certainty or precision of the treatment effect. The writing committee reviews and ranks evidence supporting each recommendation with the weight of evidence ranked as LOE A, B, or C according to specific definitions that are included in Table 1. Studies are identified as observational, retrospective, prospective, or randomized where appropriate. For certain conditions for which inadequate data are available, recommendations are based on expert consensus and clinical experience and are ranked as LOE C. When recommendations at LOE C are supported by historical clinical data, appropriate references (including clinical reviews) are cited if available. For issues for which sparse data are available, a survey of current practice among the clinicians on the writing committee is the basis for LOE C recommendations, and no references are cited. The schema for COR and LOE is summarized in Table 1, which also provides suggested phrases for writing recommendations within each COR. A new addition to this methodology is separation of the Class III recommendations to delineate if the recommendation is determined to be of "no benefit" or is associated with "harm" to the patient. In addition, in view of the increasing number of comparative effectiveness studies, comparator verbs and suggested phrases for writing recommendations for the comparative effectiveness of one treatment or strategy versus another have been added for COR I and IIa, LOE A or B only.
In view of the advances in medical therapy across the spectrum of cardiovascular diseases, the Task Force has designated the term guideline-directed medical therapy (GDMT) to represent optimal medical therapy as defined by ACCF/AHA guideline-recommended therapies (primarily Class I). This new term, GDMT, will be used herein and throughout all future guidelines.
Because the ACCF/AHA practice guidelines address patient populations (and healthcare providers) residing in North America, drugs that are not currently available in North America are discussed in the text without a specific COR. For studies performed in large numbers of subjects outside North America, each writing committee reviews the potential influence of different practice patterns and patient populations on the treatment effect and relevance to the ACCF/AHA target population to determine whether the findings should inform a specific recommendation.
The ACCF/AHA practice guidelines are intended to assist healthcare providers in clinical decision making by describing a range of generally acceptable approaches to the diagnosis, management, and prevention of specific diseases or conditions. The guidelines attempt to define practices that meet the needs of most patients in most circumstances. The ultimate judgment regarding the care of a particular patient must be made by the healthcare provider and patient in light of all the circumstances presented by that patient. As a result, situations may arise for which deviations from these guidelines may be appropriate. Clinical decision making should involve consideration of the quality and availability of expertise in the area where care is provided. When these guidelines are used as the basis for regulatory or payer decisions, the goal should be improvement in quality of care. The Task Force recognizes that situations arise in which additional data are needed to inform patient care more effectively; these areas will be identified within each respective guideline when appropriate.
Prescribed courses of treatment in accordance with these recommendations are effective only if followed. Because lack of patient understanding and adherence may adversely affect outcomes, physicians and other healthcare providers should make every effort to engage the patient's active participation in prescribed medical regimens and lifestyles. In addition, patients should be informed of the risks, benefits, and alternatives to a particular treatment and be involved in shared decision making whenever feasible, particularly for COR IIa and IIb, where the benefit-to-risk ratio may be lower.
The Task Force makes every effort to avoid actual, potential, or perceived conflicts of interest that may arise as a result of industry relationships or personal interests among the members of the writing committee. All writing committee members and peer reviewers of the guideline are required to disclose all such current relationships, as well as those existing 12 months previously. In December 2009, the ACCF and AHA implemented a new policy for relationships with industry and other entities (RWI) that requires the writing committee chair plus a minimum of 50% of the writing committee to have no relevant RWI (Appendix 1 for the ACCF/AHA definition of relevance). These statements are reviewed by the Task Force and all members during each conference call and meeting of the writing committee and are updated as changes occur. All guideline recommendations require a confidential vote by the writing committee
[GRAPHICS]
and must be approved by a consensus of the voting members. Members are not permitted to write, and must rescue themselves from voting on, any recommendation or section to which their RWI apply. Members who recused themselves from voting are indicated in the list of writing committee members, and section recusals are noted in Appendix 1. Authors' and peer reviewers' RWI pertinent to this guideline are disclosed in Appendixes 1 and 2, respectively. Additionally, to ensure complete transparency, writing committee members' comprehensive disclosure information-including RWI not pertinent to this document-is available as an online supplement.

AB The medical profession should play a central role in evaluating the evidence related to drugs, devices, and procedures for the detection, management, and prevention of disease. When properly applied, expert analysis of available data on the benefits and risks of these therapies and procedures can improve the quality of care, optimize patient outcomes, and favorably affect costs by focusing resources on the most effective strategies. An organized and directed approach to a thorough review of evidence has resulted in the production of clinical practice guidelines that assist physicians in selecting the best management strategy for an individual patient. Moreover, clinical practice guidelines can provide a foundation for other applications, such as performance measures, appropriate use criteria, and both quality improvement and clinical decision support tools.
The American College of Cardiology Foundation (ACCF) and the American Heart Association (AHA) have jointly produced guidelines in the area of cardiovascular disease since 1980. The ACCF/AHA Task Force on Practice Guidelines (Task Force), charged with developing, updating, and revising practice guidelines for cardiovascular diseases and procedures, directs and oversees this effort. Writing committees are charged with regularly reviewing and evaluating all available evidence to develop balanced, patient-centric recommendations for clinical practice.
Experts in the subject under consideration are selected by the ACCF and AHA to examine subject-specific data and write guidelines in partnership with representatives from other medical organizations and specialty groups. Writing committees are asked to perform a formal literature review; weigh the strength of evidence for or against particular tests, treatments, or procedures; and include estimates of expected outcomes where such data exist. Patient-specific modifiers, comorbidities, and issues of patient preference that may influence the choice of tests or therapies are considered. When available, information from studies on cost is considered, but data on efficacy and outcomes constitute the primary basis for the recommendations contained herein.
In analyzing the data and developing recommendations and supporting text, the writing committee uses evidence-based methodologies developed by the Task Force (1). The Class of Recommendation (COR) is an estimate of the size of the treatment effect considering risks versus benefits in addition to evidence and/or agreement that a given treatment or procedure is or is not useful/effective or in some situations may cause harm. The Level of Evidence (LOE) is an estimate of the certainty or precision of the treatment effect. The writing committee reviews and ranks evidence supporting each recommendation with the weight of evidence ranked as LOE A, B, or C according to specific definitions that are included in Table 1. Studies are identified as observational, retrospective, prospective, or randomized where appropriate. For certain conditions for which inadequate data are available, recommendations are based on expert consensus and clinical experience and are ranked as LOE C. When recommendations at LOE C are supported by historical clinical data, appropriate references (including clinical reviews) are cited if available. For issues for which sparse data are available, a survey of current
[GRAPHICS]
practice among the clinicians on the writing committee is the basis for LOE C recommendations, and no references are cited. The schema for COR and LOE is summarized in Table 1, which also provides suggested phrases for writing recommendations within each COR. A new addition to this methodology is separation of the Class III recommendations to delineate if the recommendation is determined to be of "no benefit" or is associated with "harm" to the patient. In addition, in view of the increasing number of comparative effectiveness studies, comparator verbs and suggested phrases for writing recommendations for the comparative effectiveness of one treatment or strategy versus another have been added for COR I and IIa, LOE A or B only.
In view of the advances in medical therapy across the spectrum of cardiovascular diseases, the Task Force has designated the term guideline-directed medical therapy (GDMT) to represent optimal medical therapy as defined by ACCF/AHA guideline-recommended therapies (primarily Class I). This new term, GDMT, will be used herein and throughout all future guidelines.
Because the ACCF/AHA practice guidelines address patient populations (and healthcare providers) residing in North America, drugs that are not currently available in North America are discussed in the text without a specific COR. For studies performed in large numbers of subjects outside North America, each writing committee reviews the potential influence of different practice patterns and patient populations on the treatment effect and relevance to the ACCF/AHA target population to determine whether the findings should inform a specific recommendation.
The ACCF/AHA practice guidelines are intended to assist healthcare providers in clinical decision making by describing a range of generally acceptable approaches to the diagnosis, management, and prevention of specific diseases or conditions. The guidelines attempt to define practices that meet the needs of most patients in most circumstances. The ultimate judgment regarding the care of a particular patient must be made by the healthcare provider and patient in light of all the circumstances presented by that patient. As a result, situations may arise for which deviations from these guidelines may be appropriate. Clinical decision making should involve consideration of the quality and availability of expertise in the area where care is provided. When these guidelines are used as the basis for regulatory or payer decisions, the goal should be improvement in quality of care. The Task Force recognizes that situations arise in which additional data are needed to inform patient care more effectively; these areas will be identified within each respective guideline when appropriate.
Prescribed courses of treatment in accordance with these recommendations are effective only if followed. Because lack of patient understanding and adherence may adversely affect outcomes, physicians and other healthcare providers should make every effort to engage the patient's active participation in prescribed medical regimens and lifestyles. In addition, patients should be informed of the risks, benefits, and alternatives to a particular treatment and be involved in shared decision making whenever feasible, particularly for COR IIa and IIb, where the benefit-to-risk ratio may be lower.
The Task Force makes every effort to avoid actual, potential, or perceived conflicts of interest that may arise as a result of industry relationships or personal interests among the members of the writing committee. All writing committee members and peer reviewers of the guideline are required to disclose all such current relationships, as well as those existing 12 months previously. In December 2009, the ACCF and AHA implemented a new policy for relationships with industry and other entities (RWI) that requires the writing committee chair plus a minimum of 50% of the writing committee to have no relevant RWI (Appendix 1 for the ACCF/AHA definition of relevance). These statements are reviewed by the Task Force and all members during each conference call and meeting of the writing committee and are updated as changes occur. All guideline recommendations require a confidential vote by the writing committee and must be approved by a consensus of the voting members. Members are not permitted to write, and must recuse themselves from voting on, any recommendation or section to which their RWI apply. Members who recused themselves from voting are indicated in the list of writing committee members, and section recusals are noted in Appendix 1. Authors' and peer reviewers' RWI pertinent to this guideline are disclosed in Appendixes 1 and 2, respectively. Additionally, to ensure complete transparency, writing committee members' comprehensive disclosure information-including RWI not pertinent to this document-is available as an online supplement. Comprehensive disclosure information for the Task Force is also available online at www.cardiosource.org/ACC/About-ACC/Leadership/Guidelinesand-Documents-Task-Forces.aspx. The work of the writing committee was supported exclusively by the ACCF and AHA without commercial support. Writing committee members volunteered their time for this activity.
In an effort to maintain relevance at the point of care for practicing physicians, the Task Force continues to oversee an ongoing process improvement initiative. As a result, in response to pilot projects, evidence tables (with references linked to abstracts in PubMed) have been added.
In April 2011, the Institute of Medicine released 2 reports: Finding What Works in Health Care: Standards for Systematic Reviews and Clinical Practice Guidelines We Can Trust (2,3). It is noteworthy that the ACCF/AHA guidelines are cited as being compliant with many of the proposed standards. A thorough review of these reports and of our current methodology is under way, with further enhancements anticipated.
The recommendations in this guideline are considered current until they are superseded by a focused update or the full-text guideline is revised. Guidelines are official policy of both the ACCF and AHA.

AB BACKGROUND: The definitive local therapy options for early-stage breast cancer are mastectomy and breast-conserving surgery followed by radiation therapy. Older women and those with comorbidities frequently receive breast-conserving surgery alone. The interaction of age and comorbidity with breast cancer severity and their impact on receipt of definitive therapy have not been well-studied.
STUDY DESIGN: In a cohort of 1,837 women aged 65 years and older receiving treatment for early-stage breast cancer in 6 integrated health care delivery systems in 1990-1994 and followed for 10 years, we examined predictors of receiving nondefinitive local therapy and assessed the impact on breast cancer recurrence within levels of severity, defined as level of risk for recurrence.
RESULTS: Age and comorbidity were associated with receipt of nondefinitive therapy. Compared with those at low risk, women at the highest risk were less likely to receive nondefinitive therapy (odds ratio = 0.32; 95% CI, 0.22-0.47), and women at moderate risk were about half as likely (odds ratio = 0.54; 95% CI, 0.35-0.84). Nondefinitive local therapy was associated with higher rates of recurrence among women at moderate (hazard ratio = 5.1; 95% CI, 1.9-13.5) and low risk (hazard ratio = 3.2; 95% CI, 1.1-8.9). The association among women at high risk was weak (hazard ratio = 1.3; 95% CI, 0.75-2.1).
CONCLUSIONS: Among these older women with early-stage breast cancer, decisions about therapy partially balanced breast cancer severity against age and comorbidity. However, even among women at low risk, omitting definitive local therapy was associated with increased recurrence. (J Am Coll Surg 2011;213:757-765. (C) 2011 by the American College of Surgeons)

AB Snacking may play a role in weight control. The associations of timing and frequency of snacking with observed weight change and nutrient intake were assessed in an ancillary study to a 12-month randomized controlled trial in Seattle, WA. Overweight-to-obese postmenopausal women (n=123) enrolled in the two dietary weight-loss arms from 2007 to 2008 with complete data at 12 months were included in these analyses.. Generalized linear models were used to test the associations between snacking and weight loss (percent) and nutrient intake at the 12-month time point. Participants were, on average, 58 years old and mainly non-Hispanic white (84%). Ninety-seven percent reported one or more snacks per day. Weight loss (percent) was significantly lower among mid-morning (10:30 AM to 11:29 Am) snackers (7.0%, 95% confidence interval: 4.3 to 9.7) compared to non mid-morning snackers (11.4%, 95% confidence interval: 10.2 to 12.6; P=0.005). A higher proportion of mid-morning snackers reported more than one snack per day (95.7%), compared to afternoon (82.8%) and evening (80.6%) snackers, although differences were not statistically significant (P>0.05). Women who reported two or more snacks per day vs one or no snacks per day had higher fiber intake (P=0.027). Afternoon snackers had higher fruit and vegetable intake compared to non-afternoon-snackers (P=0.035). These results suggest that snack meals can be a source for additional fruits, vegetables, and fiber-rich foods; however, snacking patterns might also reflect unhealthy eating habits and impede weight-loss progress. Future dietary weight-loss interventions should evaluate the effects of timing, frequency, and quality of snacks on weight loss. J Am Diet Assoc. 2011;111:1898-1903.

AB OBJECTIVES: To compare the effectiveness of behavioral treatment with that of antimuscarinic therapy in men without bladder outlet obstruction who continue to have overactive bladder (OAB) symptoms with alpha-blocker therapy. DESIGN: The Male Overactive Bladder Treatment in Veterans (MOTIVE) Trial was a two-site randomized, controlled, equivalence trial with 4-week alpha-blocker run-in. SETTING: Veterans Affairs Medical Center outpatient clinics. PARTICIPANTS: Volunteer sample of 143 men aged 42 to 88 who continued to have urgency and more than eight voids per day, with or without incontinence, after run-in. INTERVENTIONS: Participants were randomized to 8 weeks of behavioral treatment (pelvic floor muscle exercises, urge suppression techniques, delayed voiding) or drug therapy (individually titrated, extended-release oxybutynin, 5-30 mg/d). MEASUREMENTS: Seven-day bladder diaries and a validated urgency scale were used to calculate changes in 24-hour voiding frequency, nocturia, urgency, and incontinence. Secondary outcomes were global patient ratings and American Urological Association Symptom Index. RESULTS: Mean voids per day decreased from 11.3 to 9.1 (- 18.8%) with behavioral treatment and 11.5 to 9.5 (- 16.9%) with drug therapy. Equivalence analysis indicated that posttreatment means were equivalent (P <.01). After treatment, 85% of participants rated themselves as much better or better; more than 90% were completely or somewhat satisfied, with no betweengroup differences. The behavioral group showed greater reductions in nocturia (mean = -0.70 vs - 0.32 episodes/ night; P =.05). The drug group showed greater reductions in maximum urgency scores (mean = -0.44 vs -0.12; P =.02). Other between-group differences were nonsignificant. CONCLUSION: Behavioral and antimuscarinic therapy are effective when added to alpha-blocker therapy for OAB in men without outlet obstruction. Behavioral treatment is at least as effective as antimuscarinic therapy. J Am Geriatr Soc 59: 2209-2216, 2011.

AB OBJECTIVES: To examine the association between sleep architecture, sleep-disordered breathing, and cognition in older men. DESIGN: Population-based cross-sectional study. SETTING: Six clinical sites in the United States. PARTICIPANTS: Two thousand nine hundred nine community- dwelling men aged 67 and older who were not selected on the basis of sleep problems or cognitive impairment. MEASUREMENTS: Predictors were measured using in-home polysomnography: sleep architecture, nocturnal hypoxemia (any sleep time with arterial oxygen saturation < 80%), apnea-hypopnea index (AHI), and arousal index. Cognitive outcomes were measured using the modified Mini-Mental State Examination (3MS), Trail-Making Test Part B (TMT-B), and the Digit Vigilance Test (DVT). RESULTS: Analyses adjusted for age, race, education, body mass index, lifestyle, comorbidities, and medication use showed that participants who spent less percentage of time in rapid eye movement (REM) sleep had lower levels of cognition; participants in the lowest quartile (< 14.8%) took an average of 5.9 seconds longer on the TMT-B and 20.1 seconds longer on the DVT than those in the highest quartile (>= 23.7%). Similarly, greater percentage of time spent in Stage 1 sleep was related to poorer cognitive function. Participants in the highest quartile of Stage 1 sleep (>= 8.6%) had worse cognitive scores on average than those in the lowest quartile (< 4.0%). Those with nocturnal hypoxemia took an average of 22.3 seconds longer to complete the DVT than those without, but no associations were found with 3MS or the TMT-B. CONCLUSION: Spending less percentage of time in REM sleep and greater percentage of time in Stage 1 sleep and having higher levels of nocturnal hypoxemia were associated with poorer cognition in older men. Further studies are needed to clarify the direction of these associations and to explore potential mechanisms. J Am Geriatr Soc 59: 2217-2225, 2011.

AB OBJECTIVES: To evaluate whether the use of angiotensin- converting enzyme (ACE) inhibitors and statins is associated with a lower risk of incident mobility limitation in older community dwelling adults. DESIGN: Longitudinal cohort study. SETTING: Health, Aging and Body Composition (Health ABC) study. PARTICIPANTS: Three thousand fifty-five participants who were well functioning at baseline (no mobility limitations). MEASUREMENTS: Summated standardized daily doses (low, medium, high) and duration of ACE inhibitor and statin use were computed. Mobility limitation (two consecutive self-reports of having any difficulty walking onequarter of a mile or climbing 10 steps without resting) was assessed every 6 months after baseline. Multivariable Cox proportional hazards analyses were conducted, adjusting for demographics, health status, and health behaviors. RESULTS: At baseline, 15.2% used ACE inhibitors and 12.9% used statins; use of both was greater than 25% by Year 6. Over 6.5 years of follow-up, 49.8% had developed mobility limitation. In separate multivariable models, neither ACE inhibitor (multivariate hazard ratio (HR) = 0.95, 95% confidence interval (CI) = 0.82-1.09) nor statin use (multivariate HR = 1.02, 95% CI = 0.87-1.17) was associated with lower risk of mobility limitation. Similar findings were seen in analyses examining dose-response and duration-response relationships and a sensitivity analysis restricted to those with hypertension. CONCLUSION: ACE inhibitors and statins widely prescribed to treat hypertension and hypercholesterolemia, respectively, do not lower risk of mobility limitation, an important indicator of quality of life.

AB OBJECTIVES: To examine the relationship between management of diabetes mellitus and hypoglycemia in older adults with and without dementia and cognitive impairment. DESIGN: Cross-sectional database analysis of veterans aged 65 years and older stratified according to dementia, cognitive impairment, age, antiglycemic medications, and glycosylated hemoglobin (Hba1c) level. SETTING: Research database with linked clinical, laboratory, pharmacy, and International Classification of Diseases, Ninth Revision, Clinical Modification, codes. PARTICIPANTS: Four hundred ninety-seven thousand nine hundred veterans aged 65 and older with diabetes mellitus who obtained services from the Department of Veterans Affairs in fiscal years (FYs) 2002 and 2003. MEASUREMENTS: Hypoglycemia, the outcome variable, was identified from outpatient visits, emergency department and inpatient admission codes in FY2003. Independent variables (FY2002-03) included dementia and cognitive impairment, comorbid conditions, extended care and nursing home stays, demographics, antiglycemic medication, and HbA1c levels. RESULTS: Prevalence of combined dementia and cognitive impairment was 13.1% for individuals aged 65 to 74 and 24.2% for those aged 75 and older. Mean HbA1c levels were 7.0 +/- 1.3% for all participants and 6.9 +/- 1.3% for those with dementia. The proportion of participants taking insulin was higher in those with dementia or cognitive impairment (30%) than in those with neither condition (24%). Of all participants taking insulin, more with dementia (26.5%) and cognitive impairment (19.5%) were hypoglycemic than of those with neither condition (14.4%). For all participants, unadjusted odds ratios (ORs) for hypoglycemia were 2.42 (95% confidence interval (CI) = 2.36-2.48) for dementia and 1.72 (95% CI = 1.65-1.79) for cognitive impairment; adjusted ORs were 1.58 (95% CI = 1.53-1.62) for dementia and 1.13 (95% CI = 1.08-1.18) for cognitive impairment. CONCLUSION: Diabetes mellitus was managed more intensively in older veterans with dementia and cognitive impairment, and dementia and cognitive impairment were independently associated with greater risk of hypoglycemia.

AB OBJECTIVES: To investigate patient-level determinants of in-hospital death, adjusting for patient and regional characteristics. DESIGN: Using multivariable regression, the relationship between in-hospital death and participants' social, functional, and health characteristics was investigated, controlling for regional Hospital Care Intensity Index (HCI) from the Dartmouth Atlas of Health Care. SETTING: The Health and Retirement Study, a longitudinal nationally representative cohort of older adults. PARTICIPANTS: People aged 67 and older who died between 2,000 and 2,006 (N = 3,539) were sampled. MEASUREMENTS: In-hospital death. RESULTS: Thirty-nine percent (n = 1,380) of participants died in the hospital (range 34% in Midwest to 45% in Northeast). Nursing home residence, functional dependence, and cancer or dementia diagnosis, among other characteristics, were associated with lower adjusted odds of in-hospital death. Being black or Hispanic, living alone, and having more medical comorbidities were associated with greater adjusted odds, as was higher HCI. Sex, education, net worth, and completion of an advance directive did not correlate with in-hospital death. CONCLUSION: Black race, Hispanic ethnicity, and other functional and social characteristics are correlates of inhospital death, even after controlling for the role of HCI. Further work must be done to determine whether preferences, provider characteristics and practice patterns, or differential access to medical and community services drive this difference.

AB Background Autologous haemopoietic stem-cell transplantation (HSCT) improves survival in patients with multiple myeloma, but disease progression remains an issue. Allogeneic HSCT might reduce disease progression, but can be associated with high treatment-related mortality. Thus, we aimed to assess effectiveness of allogeneic HSCT with non-myeloablative conditioning after autologous HSCT compared with tandem autologous HSCT.
Methods In our phase 3 biological assignment trial, we enrolled patients with multiple myeloma attending 37 transplant centres in the USA. Patients (<70 years old) with adequate organ function who had completed at least three cycles of systemic antimyeloma therapy within the past 10 months were eligible for inclusion. We assigned patients to receive an autologous HSCT followed by an allogeneic HSCT (auto-allo group) or tandem autologous HSCTs (auto-auto group) on the basis of the availability of an HLA-matched sibling donor. Patients in the auto-auto group subsequently underwent a random allocation (1: 1) to maintenance therapy (thalidomide plus dexamethasone) or observation. To avoid enrolment bias, we classified patients as standard risk or high risk on the basis of cytogenetics and beta 2-microglobulin concentrations. We used the Kaplan-Meier method to estimate differences in 3-year progression-free survival (PFS; primary endpoint) between patients with standard-risk disease in the auto-allo group and the best results from the auto-auto group (maintenance, observation, or pooled). This study is registered with ClinicalTrials.gov, number NCT00075829.
Findings Between Dec 17, 2003, and March 30, 2007, we enrolled 710 patients, of whom 625 had standard-risk disease and received an autologous HSCT. 156 (83%) of 189 patients with standard-risk disease in the auto-allo group and 366 (84%) of 436 in the auto-auto group received a second transplant. 219 patients in the auto-auto group were randomly assigned to observation and 217 to receive maintenance treatment, of whom 168 (77%) completed this treatment. PFS and overall survival did not differ between maintenance and observation groups and pooled data were used. Kaplan-Meier estimates of 3-year PFS were 43% (95% CI 36-51) in the auto-allo group and 46% (42-51) in the auto-auto group (p=0.671); overall survival also did not differ at 3 years (77% [95% CI 72-84] vs 80% [77-84]; p=0.191). Within 3 years, 87 (46%) of 189 patients in the auto-allo group had grade 3-5 adverse events as did 185 (42%) of 436 patients in the auto-auto group. The adverse events that differed most between groups were hyperbilirubinaemia (21 [11%] patients in the auto-allo group vs 14 [3%] in the auto-auto group) and peripheral neuropathy (11 [6%] in the auto-allo group vs 52 [12%] in the auto-auto group).
Interpretation Non-myeloablative allogeneic HSCT after autologous HSCT is not more effective than tandem autologous HSCT for patients with standard-risk multiple myeloma. Further enhancement of the graft versus myeloma effect and reduction in transplant-related mortality are needed to improve the allogeneic HSCT approach.

AB Significant sex differences in the well-documented relationship between stress hormones and memory have emerged in recent studies. The potentiating effects of glucocorticoids on memory vary across the menstrual cycle, suggesting a potential interaction between these stress hormones and endogenously cycling sex hormones. Here, we show that memory for emotional materials changes significantly in accordance with hormonal changes across the menstrual cycle, suggesting that ovarian sex hormones influence the modulation of emotional memories. Sixty healthy, naturally cycling women rated 120 images on arousal and valence. One week later they completed free recall and recognition memory tests. Their menstrual cycle phases were estimated by self-report and confirmed by salivary assay of 17 beta-estradiol and progesterone. Memory for emotional items only was significantly better in the high hormone (luteal) phase compared with the low hormone (follicular) phase on the free recall test; on both tests memory correlated positively with progesterone collected at the time of encoding. These findings suggest that emotional memory performance changes across the menstrual cycle, and that this change is in part mediated by endogenous progesterone cycling.

AB Polyphenols are a large family of naturally occurring plant products and are widely distributed in plant foods, such as, fruits, vegetables, nuts, flowers, bark and seeds, etc. These polyphenols contribute to the beneficial health effects of dietary products. Clinical and epidemiological studies suggest that exposure of the skin to environmental factors/pollutants, such as solar ultraviolet (UV) radiation induce harmful effects and leads to various skin diseases including the risk of melanoma and non-melanoma skin cancers. The incidence of non-melanoma skin cancer, comprising of squamous cell carcinoma and basal cell carcinoma, is a significant public health concern world-wide. Exposure of the skin to solar UV radiation results in inflammation, oxidative stress, DNA damage, dysregulation of cellular signaling pathways and immunosuppression thereby resulting in skin cancer. The regular intake of natural plant products, especially polyphenols, which are widely present in fruits, vegetables, dry legumes and beverages have gained considerable attention as protective agents against the adverse effects of UV radiation. In this article, we first discussed the impact of polyphenols on human health based on their structure-activity relationship and bioavailability. We then discussed in detail the photoprotective effects of some selected polyphenols on UV-induced skin inflammation, proliferation, immunosuppression, DNA damage and dysregulation of important cellular signaling pathways and their implications in skin cancer management. The selected polyphenols include: green tea polyphenols, pomegranate fruit extract, grape seed proanthocyanidins, resveratrol, silymarin, genistein and delphinidin. The new information on the mechanisms of action of these polyphenols supports their potential use in skin photoprotection and prevention of photocarcinogenesis in humans.

AB Low adiponectin levels are an independent risk factor for and mediate the effect of obesity on endometrial cancer in epidemiology studies. The direct or indirect mechanisms underlying these findings remain to be elucidated. We first examined the expression of adiponectin receptor 1 (AdipoR1) and 2 (AdipoR2) in normal human endometrium and in endometrial cancer tissues ex vivo. We then used KLE and RL95-2 human endometrial cancer cell lines in vitro to study relative expression of AdipoRs, to investigate the effect of adiponectin on activating intracellular signaling pathways, and to assess its potential to alter malignant properties. We report for the first time that the relative expression level of AdipoR1 is higher than AdipoR2 in human endometrial cancer tissue, but the expression of AdipoRs is not statistically different from nonneoplastic tissues. We also show for the first time in endometrial cancer cell lines in vitro that adiponectin suppresses endometrial cancer proliferation acting through AdipoRs. Adiponectin also increases the expression of the adaptor molecule LKB1, which is required for adiponectin-mediated activation of AMPK/S6 axis and modulation of cell proliferation, colony formation, adhesion, and invasion of KLE and RL95-2 cell lines. These novel mechanistic studies provide for the first time in vitro and ex vivo evidence for a causal role of adiponectin in endometrial cancer. Mol Cancer Ther; 10(12); 2234-43. (C)2011 AACR.

AB A variety of mechanisms confer hypersensitivity of tumor cells to the macrolide rapamycin, the prototypic mTORC1 inhibitor. Several studies have shown that the status of the AKT kinase plays a critical role in determining hypersensitivity. Cancer cells in which AKT activity is elevated are exquisitely sensitive to mTORC1 inhibitors while cells in which the kinase is quiescent are relatively resistant. Our previous work has shown that a transcript-specific protein synthesis salvage pathway is operative in cells with quiescent AKT levels, maintaining the translation of crucial mRNAs involved in cell-cycle progression in the face of global eIF-4E-mediated translation inhibition. The activation of this salvage pathway is dependent on SAPK2/p38-mediated activation of IRES-dependent initiation of the cyclin D1 and c-MYC mRNAs, resulting in the maintenance of their protein expression levels. Here, we show that both genetic and pharmacologic inhibition of SAPK2/p38 in glioblastoma multiforme cells significantly reduces rapamycin-induced IRES-mediated translation initiation of cyclin D1 and c-MYC, resulting in increased G(1) arrest in vitro and inhibition of tumor growth in xenografts. Moreover, we observed that the AKT-dependent signaling alterations seen in vitro are also displayed in engrafted tumors cells and were able to show that combined inhibitor treatments markedly reduced the mRNA translational state of cyclin D1 and c-MYC transcripts in tumors isolated from mice. These data support the combined use of SAPK2/p38 and mTORC1 inhibitors to achieve a synergistic antitumor therapeutic response, particularly in rapamycin-resistant quiescent AKT-containing cells.

AB Studies have demonstrated that TLR4 and TLR2 expression by monocytes and the blood levels of TLR4 and TLR2 ligand in diabetic patients are significantly incased compared to nondiabetic patients, indicating that more monocytes in diabetic patients may have coactivation of TLR4 and TLR2. Although it has been shown that either TLR4 or TLR2 activation leads to increased expression of proinflammatory cytokines, the effect of coactivation of TLR2 and TLR4 in mononuclear cells on proinflammatory cytokine expression and the underlying molecular mechanisms remain largely unknown. In this study, we found that while TLR1, TLR2, TLR4 and TLR6 were expressed by U937 mononuclear cells, TLR4 was expressed at the highest level. Interestingly, results showed that while activation of either TLR4 or TLR2/6 (TLR2dimerized with TLR6), but not TLR2/1 (TLR2dimerized with TLR1), significantly increased IL-6 expression by U937 mononuclear cells, coactivation of TLR4 and TLR2/6, but not TLR4 and TLR2/1, led to a further augmentation on IL-6 expression by increasing IL-6 transcriptional activity, but not mRNA stability. To explore the signaling mechanisms involved in the augmentation, we found that p38MAPK and NF kappa B pathways, but not ERK and JNK pathways, were required for the augmentation of IL-6 expression by coactivation of TLR4 and TLR2/6. Furthermore, we found that coactivation of TLR4 and TLR2/6 increased p38 phosphorylation, but not NFkB activity, as compared to activation of TLR4or TLR2/6 alone. Taken together, this study showed that coactivation of TLR4 and TLR2/6 coordinates an additive augmentation of IL-6 gene transcription via p38MAPK pathway in U937 mononuclear cells.

AB Photodynamic therapy (PDT) employs the combination of nontoxic photosensitizers and visible light that is absorbed by the chromophore to produce long-lived triplet states that can carry out photochemistry in the presence of oxygen to kill cells. The closed carbon-cage structure found in fullerenes can act as a photosensitizer, especially when functionalized to impart water solubility. Although there are reports of the use of fullerenes to carry out light-mediated destruction of viruses, microorganisms and cancer cells in vitro, the use of fullerenes to mediate PDT of diseases such as cancer and infections in animal models is less well developed. It has recently been shown that fullerene PDT can be used to save the life of mice with wounds infected with pathogenic Gram-negative bacteria. Fullerene PDT has also been used to treat mouse models of various cancers including disseminated metastatic cancer in the peritoneal cavity. In vivo PDT with fullerenes represents a new application in nanomedicine.

AB Caspase 8 initiates apoptosis downstream of TNF death receptors by undergoing autocleavage and processing the executioner caspase 3 (ref. 1). However, the dominant function of caspase 8 is to transmit a pro-survival signal that suppresses programmed necrosis (or necroptosis) mediated by RIPK1 and RIPK3 (refs 2-6) during embryogenesis and haematopoiesis(7-9). Suppression of necrotic cell death by caspase 8 requires its catalytic activity but not the autocleavage essential for apoptosis(10); however, the key substrate processed by caspase 8 to block necrosis has been elusive. A key substrate must meet three criteria: it must be essential for programmed necrosis; it must be cleaved by caspase 8 in situations where caspase 8 is blocking necrosis; and mutation of the caspase 8 processing site on the substrate should convert a pro-survival response to necrotic death without the need for caspase 8 inhibition. We now identify CYLD as a substrate for caspase 8 that satisfies these criteria. Following TNF stimulation, caspase 8 cleaves CYLD to generate a survival signal. In contrast, loss of caspase 8 prevented CYLD degradation, resulting in necrotic death. A CYLD substitution mutation at Asp 215 that cannot be cleaved by caspase 8 switches cell survival to necrotic cell death in response to TNF.

AB DNA molecules have been used to build a variety of nanoscale structures and devices over the past 30 years, and potential applications have begun to emerge. But the development of more advanced structures and applications will require a number of issues to be addressed, the most significant of which are the high cost of DNA and the high error rate of self-assembly. Here we examine the technical challenges in the field of structural DNA nanotechnology and outline some of the promising applications that could be developed if these hurdles can be overcome. In particular, we highlight the potential use of DNA nanostructures in molecular and cellular biophysics, as biomimetic systems, in energy transfer and photonics, and in diagnostics and therapeutics for human health.

AB Immune cells in the tumor microenvironment have an important role in regulating tumor progression. Therefore, stimulating immune reactions to tumors can be an attractive therapeutic and prevention strategy. Cancer cells and host cells constantly interact with each other in the tumor microenvironment; thus, cancer immunology is an interdisciplinary area where integrated analysis of both host and tumor factors is needed. Cancer represents a heterogeneous group of diseases with different genetic and epigenetic alterations; therefore, molecular classification of cancer (for example lung, prostate and breast cancers) is an important component in clinical decision making. However, most studies on antitumor immunity and clinical outcome lack analysis of tumor molecular biomarkers. In this Review, we discuss colorectal cancer as a prototypical example of cancer. Common molecular classifiers of colon cancer include KRAS, BRAF and PIK3CA mutations, microsatellite instability, LINE-1 methylation, and CpG island methylator phenotype. Since tumor molecular features and immune reactions are inter-related, a comprehensive assessment of these factors is critical. Examining the effects of tumor-host interactions on clinical outcome and prognosis represents an evolving interdisciplinary field of molecular pathological epidemiology. Pathological immunity evaluation may provide information on prognosis and help identify patients who are more likely to benefit from immunotherapy.

AB The ability to generate induced pluripotent stem cells (iPSCs) from patients, and an increasingly refined capacity to differentiate these iPSCs into disease-relevant cell types, promises a new paradigm in drug development - one that positions human disease pathophysiology at the core of preclinical drug discovery. Disease models derived from iPSCs that manifest cellular disease phenotypes have been established for several monogenic diseases, but iPSCs can likewise be used for phenotype-based drug screens in complex diseases for which the underlying genetic mechanism is unknown. Here, we highlight recent advances as well as limitations in the use of iPSC technology for modelling a'disease in a dish' and for testing compounds against human disease phenotypes in vitro. We discuss how iPSCs are being exploited to illuminate disease pathophysiology, identify novel drug targets and enhance the probability of clinical success of new drugs.

AB Functional magnetic resonance imaging (fMRI) is a relative newcomer in the field of biomarkers for Alzheimer's disease (AD). fMRI has several potential advantages, particularly for clinical trials, as it is a noninvasive imaging technique that does not require the injection of contrast agent or radiation exposure and thus can be repeated many times during a longitudinal study. fMRI has relatively high spatial and reasonable temporal resolution, and can be acquired in the same session as structural magnetic resonance imaging. Perhaps most importantly, fMRI may provide useful information about the functional integrity of brain networks supporting memory and other cognitive domains, including the neural correlates of specific behavioral events, such as successful versus failed memory formation.

ID ALZHEIMERS-DISEASE; DEMENTIA; CONSORTIUM; DIAGNOSIS; SERIES
AB Background and objective: Posterior cortical atrophy (PCA) is a progressive neurodegenerative syndrome that presents with cortical visual dysfunction and relatively preserved memory. Although higher cortical visual syndromes are well known in PCA, visual field defects detected by computerized visual field (CVF) perimetry have not been systematically described. The objective of this study was to describe CVF defects measured by threshold perimetry in PCA.
Methods: This was a retrospective case series of patients meeting proposed PCA diagnostic criteria seen in the Neuro-ophthalmology and Neurobehavior Clinics at the University of Colorado during 2002 to 2006. History, examination, neuroimaging, autopsy, and CVF studies were analyzed.
Results: Nine of 11 patients who met the criteria for PCA and had CVF testing were included. Seven of the 9 patients had homonymous hemianopia or quadrantanopia, and 2 had bilateral constriction. All patients progressed to dementia. Criteria were met for probable Alzheimer disease (AD) in 7, definite AD in 1, and definite dementia with Lewy bodies associated with AD pathology in 1. Seven of 9 patients had early and prominent complaints of difficulty driving.
Conclusions: CVF defects were characterized by homonymous visual field defects or bilateral constriction. Eight of 9 patients progressed to probable or definite AD, but the CVF defects were distinctly different from those in typical AD. This observation probably reflects a posterior shift of cortical pathology to the primary and early secondary visual cortices in PCA. CVF testing should be considered in older patients with unexplained visual complaints, particularly when associated with difficulty driving, which may indicate the possibility of PCA and prompt early neurobehavioral evaluation.

TI Validating Smoking Data From the Veteran's Affairs Health Factors
Dataset, an Electronic Data Source

AB We assessed smoking data from the Veterans Health Administration (VHA) electronic medical record (EMR) Health Factors dataset.
To assess the validity of the EMR Health Factors smoking data, we first created an algorithm to convert text entries into a 3-category smoking variable (never, former, and current). We compared this EMR smoking variable to 2 different sources of patient self-reported smoking survey data: (a) 6,816 HIV-infected and -uninfected participants in the 8-site Veterans Aging Cohort Study (VACS-8) and (b) a subset of 13,689 participants from the national VACS Virtual Cohort (VACS-VC), who also completed the 1999 Large Health Study (LHS) survey. Sensitivity, specificity, and kappa statistics were used to evaluate agreement of EMR Health Factors smoking data with self-report smoking data.
For the EMR Health Factors and VACS-8 comparison of current, former, and never smoking categories, the kappa statistic was .66. For EMR Health Factors and VACS-VC/LHS comparison of smoking, the kappa statistic was .61.
Based on kappa statistics, agreement between the EMR Health Factors and survey sources is substantial. Identification of current smokers nationally within the VHA can be used in future studies to track smoking status over time, to evaluate smoking interventions, and to adjust for smoking status in research. Our methodology may provide insights for other organizations seeking to use EMR data for accurate determination of smoking status.

TI Increased Risk of Preterm Delivery Among HIV-Infected Women Randomized
to Protease Versus Nucleoside Reverse Transcriptase Inhibitor-Based
HAART During Pregnancy EDITORIAL COMMENT
SO OBSTETRICAL & GYNECOLOGICAL SURVEY
LA English
DT Editorial Material
AB The World Health Organization recommends the use of highly active antiretroviral therapy (HAART) for prevention of mother-to-child transmission of human immunodeficiency virus during pregnancy and breast-feeding. Some observational studies have reported that use of protease inhibitor (PI)-based HAART is associated with preterm delivery, but others have reported no such association.
This retrospective analysis of a previously published randomized trial was designed to determine whether the use of PI for prevention of mother-to-child transmission in late pregnancy increases the risk for preterm delivery (<37 weeks' gestation). Maternal weight gain in late pregnancy was also evaluated as a potentially associated risk factor for preterm delivery. The study subjects were 560 human immunodeficiency virus-infected, HAART-naive pregnant women with CD4+ counts (plus is superior) >= 200 cells/mm(3). Between 26 and 34 weeks of gestation, the women were randomized to receive either lopinavir/ritonavir/zidovudine/lamivudine (PI group, n = 267) or abacavir/zidovudine/lamivudine (nucleoside reverse transcriptase inhibitor [NRTI] group, n = 263).
With univariate analysis, the rate of preterm delivery was found to be significantly higher in the PI group compared with the NRTI group (21.4% vs. 11.8%, P = 0 0.003). Multivariate analysis showed that use of the PI-based HAART regimen was associated with a 2-fold higher rate of preterm delivery compared with the NRTI-based regimen; the adjusted odds ratio was 2.02, with a 95% confidence interval of 1.26 to 3.27; P = 0.004. The mean change in maternal body mass index 1 month after HAART initiation (surrogate for weight gain) was significantly lower in the PI group than in the NRTI group (P < 0.001). The reduced weight gain, however, was not significantly associated with preterm delivery. There was no difference in the frequency of infant hospitalizations or mortality between the regimens until 6 months of life.
These findings show an association between use of a PI-based HAART regimen in late pregnancy and preterm delivery.

AB EphA2 is a member of the Eph family of receptor tyrosine kinases and is highly expressed in many aggressive cancer types, including melanoma. We recently showed that EphA2 is also upregulated by ultraviolet radiation and is able to induce apoptosis. These findings suggest that EphA2 may have different, even paradoxical, effects on viability depending on the cellular context and that EphA2 mediates a delicate balance between life and death of the cell. To functionally clarify EphA2's role in melanoma, we analyzed a panel of melanoma cell lines and found that EphA2 levels are elevated in a significant fraction of the samples. Specific depletion of EphA2 in high-expressing melanoma cells using short hairpin RNA led to profound reductions in cellular viability, colony formation and migration in vitro and a dramatic loss of tumorigenic potential in vivo. Stable introduction of EphA2 into low-expressing cell lines enhanced proliferation, colony formation and migration, further supporting its pro-malignant phenotype. Interestingly, transient expression of EphA2 and/or Braf(V600E) in non-transformed melanocytes led to significant and additive apoptosis. These results verify that EphA2 is an important oncogene and potentially a common source of 'addiction' for many melanoma cells. Moreover, acute induction of EphA2 may purge genetically susceptible cells, thereby uncovering a more aggressive population that is in fact dependent on the oncogene.

Treatment Protocol for Center-Involved Diabetic Macular Edema

ID OPTICAL COHERENCE TOMOGRAPHY; LASER; PHOTOCOAGULATION
AB Objective: To describe the underlying principles used to develop a web-based algorithm that incorporated intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment for diabetic macular edema (DME) in a Diabetic Retinopathy Clinical Research Network (DRCR.net) randomized clinical trial.
Design: Discussion of treatment protocol for DME.
Participants: Subjects with vision loss resulting from DME involving the center of the macula.
Methods: The DRCR.net created an algorithm incorporating anti-VEGF injections in a comparative effectiveness randomized clinical trial evaluating intravitreal ranibizumab with prompt or deferred (>= 24 weeks) focal/grid laser treatment in eyes with vision loss resulting from center-involved DME. Results confirmed that intravitreal ranibizumab with prompt or deferred laser provides superior visual acuity outcomes compared with prompt laser alone through at least 2 years. Duplication of this algorithm may not be practical for clinical practice. To share their opinion on how ophthalmologists might emulate the study protocol, participating DRCR.net investigators developed guidelines based on the algorithm's underlying rationale.
Main Outcome Measures: Clinical guidelines based on a DRCR.net protocol.
Results: The treatment protocol required real-time feedback from a web-based data entry system for intravitreal injections, focal/grid laser treatment, and follow-up intervals. Guidance from this system indicated whether treatment was required or given at investigator discretion and when follow-up should be scheduled. Clinical treatment guidelines, based on the underlying clinical rationale of the DRCR.net protocol, include repeating treatment monthly as long as there is improvement in edema compared with the previous month or until the retina is no longer thickened. If thickening recurs or worsens after discontinuing treatment, treatment is resumed.
Conclusions: Duplication of the approach used in the DRCR.net randomized clinical trial to treat DME involving the center of the macula with intravitreal ranibizumab may not be practical in clinical practice, but likely can be emulated based on an understanding of the underlying rationale for the study protocol. Inherent differences between a web-based treatment algorithm and a clinical approach may lead to differences in outcomes that are impossible to predict. The closer the clinical approach is to the algorithm used in the study, the more likely the outcomes will be similar to those published.

AB Graded-index (GRIN) lenses serve as a key component for miniature endoscopes because of their small diameters and ease of assembly. However, the nonaplanatic nature of GRIN lenses causes inherent spatial aberrations that lower image resolution and sharpness. Here we present the diagnosis of the aberrations in GRIN probes and the use of adaptive optics to compensate for the wavefront errors in the endoscope. Two different operation schemes based on preset and in situ measurements are demonstrated, both resulting in a substantial reduction of the wavefront error from 0.42 to < 0.1 mu m.

AB Background: Although implantable cardioverter-defibrillators (ICDs) reduce mortality in selected patients, they are also associated with potential risks. Periprocedural decision making requires understanding both benefits and risks.
Methods: This qualitative study aims to understand cardiologists' and patients' perspectives about decision making surrounding ICD implantation using semi-structured, in-depth interviews. We interviewed 11 cardiologists (including four electrophysiologists) and 20 patients (14 with ICDs; six who declined ICDs). The data were analyzed through the theoretical lens of patient-centered care using the constant comparative method.
Results: Cardiologists emphasized the benefits of ICD therapy but varied substantially in the extent to which they emphasized the various risks associated with ICD implantation with patients. Cardiologists indicated that they were influenced by the benefits of therapy as presented in published guidelines. Many patients who chose to receive an ICD indicated that they followed the advice of their physician without questioning the risks and benefits of the device. Some ICD recipients described not learning many of the risks until after device implantation or when they experienced these side effects. Patients who declined ICD implantation were concerned that the ICD was unnecessary or believed that the risks related to sudden death without an ICD did not apply to them. Only one patient considered the trade-off between dying quickly versus living longer with progressive heart failure.
Conclusions: In our sample, cardiologists' desire to adhere to published guidelines appears to inhibit shared decision making. The marked variability in the discussions surrounding ICD decisions highlights a need for an improved process of ICD decision making. (PACE 2011; 34: 1634-1644)

AB Objective: To test an active-learning, empowerment approach to teaching patients about the "diabetes ABCs" (hemoglobin A(1)C, systolic blood pressure, and low density lipoprotein cholesterol).
Methods: 84 (97%) diabetic patients who participated in a randomized effectiveness trial of two clinic-based group educational methods and completed a post-intervention assessment. The empowerment arm participated in a group session that incorporated two educational innovations (a conceptual metaphor to foster understanding, and team-based learning methods to foster active learning). The traditional diabetes education arm received a didactic group session focused on self-management and educational materials about the diabetes ABCs. Participants in both arms received individual review of their current ABC values.
Results: A questionnaire evaluated knowledge, understanding, and recall of the diabetes ABCs was administered three months after enrollment in the study. At three months, participants in the empowerment group demonstrated greater understanding of the diabetes ABCs (P < 0.0001), greater knowledge of their own values (P < 0.0001), and greater knowledge of guideline-derived target goals for the ABCs compared with participants in the traditional arm (P < 0.0001).
Conclusion: An active-learning, empowerment-based approach applied to diabetes education can lead to greater understanding and knowledge retention. Practice implications: An empowerment approach to education can facilitate informed, activated patients and increase performance of self-management behaviors. Published by Elsevier Ireland Ltd.

AB Objective: Health information-seeking behaviors (HISBs) are associated with active participation in cancer care decisions which, in turn, may positively impact health outcomes. The goal of this study was to develop a taxonomy of topics for which post-treatment cancer patients sought information, and to explore HISB patterns by sociodemographic factors and cancer type.
Methods: We examined how health information seeking is associated with social determinants in a survey of 521 post-treatment cancer patients.
Results: Four major topics of interest were found: disease/treatment, self-care management, health services, and work/finance. Assessment of the relationship between social determinants and these four topics showed associations for (1) HISBs on disease/treatment topics decreased with age and increased with education; (2) HISBs on self-care management increased with education and varied by cancer type; (3) HISBs on health services increased with education; and (4) HISBs on work/finance decreased with age and wealth, but increased with debt.
Conclusion: These results demonstrate one pathway through which social determinants may drive communication inequalities, which may result in increased disparities in health outcomes. Practice implications: Further exploration of the relationship between social determinants and information-seeking among post-treatment cancer patients may contribute to the development of strategies to reduce health disparities.

AB Background: Over-use of antibiotics for acute respiratory infections (ARIs) increases antimicrobial resistance, treatment costs, and side effects. Patient desire for antibiotics contributes to over-use.
Objective: To explore whether a point-of-care interactive computerized education module increases patient knowledge and decreases desire for antibiotics.
Methods: Bilingual (English/Spanish) interactive kiosks were available in 8 emergency departments as part of a multidimensional intervention to reduce antibiotic prescribing for ARIs. The symptom-tailored module included assessment of symptoms, knowledge about ARIs (3 items), and desire for antibiotics on a 10-point visual analog scale. Multivariable analysis assessed predictors of change in desire for antibiotics.
Results: Of 686 adults with ARI symptoms. 63% initially thought antibiotics might help. The proportion of patients with low (1-3 on the scale) desire for antibiotics increased from 22% pre-module to 49% post-module (p < .001). Self-report of "learning something new" was associated with decreased desire for antibiotics, after adjusting for baseline characteristics (p = .001).
Conclusion: An interactive educational kiosk improved knowledge about antibiotics and ARIs. Learning correlated with changes in personal desire for antibiotics. Practice implications: By reducing desire for antibiotics, point-of-care interactive educational computer technology may help decrease inappropriate use for antibiotics for ARIs.

AB Objectives: To evaluate the effect of functional health literacy (FHL) on preferences for decision-making; and among those initially preferring a passive decision-making role, to explore how preferences change if their physician actively encourages their involvement.
Methods: Consecutive older adults with cardiovascular disease receiving complex antithrombotic therapy completed a comprehensive assessment including measures of FHL and preferences for shared decision making.
Results: Half of all participants had inadequate or marginal FHL. Those with inadequate FHL were more likely (P = 0.01) to prefer passive rather than active decision making styles even after controlling for age, education, and numeracy. However, 40% of patients preferring passive styles had adequate FHL and these patients were significantly more likely to change their preference to more active styles (odds ratio = 7.17, P < .01) if their physician "was more supportive or encouraged participation".
Conclusions: Screening FHL can provide insight into patients' preferences for active participation in decision making. Clinicians' encouragement of participation can increase engagement by patients with adequate FHL.
Practice implications: We propose an algorithm for screening FHL and preferences for participating in decisions about complex medication regimens. Published by Elsevier Ireland Ltd.

AB Recent studies have shown that osteopontin, a cytokine with suggested immunoregulatory functions, may contribute to pathogenesis of asthma. To determine whether single-nucleotide polymorphisms (SNPs) in SPP1, the gene encoding osteopontin, are associated with risk of asthma, we genotyped 6 known SNPs in SPP1 in the well-characterized Genetics of Asthma in Latino Americans population of 294 Mexican and 365 Puerto Rican parent-child asthma trios. The associations between SNPs and asthma or asthma-related phenotypes were examined by transmission disequilibrium tests as implemented in the family-based association test program. Three polymorphisms, 1 in exon 7 (rs1126616C) and 2 in the 3'-untranslated region (rs1126772A and rs9138A) of SPP1, were associated with diagnosis of asthma, severity of asthma, asthma in subjects with elevated immunoglobulin E (IgE) (IgE > 100 IU/mL), and postbronchodilator FEV(1) in Puerto Ricans (P values = 0.00007-0.04). The CC genotype of rs1126616 conferred an odds ratio of 1.7 (95% CI = [1.3, 2.3], P value adjusted for multiple comparisons = 0.001) for asthma compared with the CT and TT genotypes. Furthermore, haplotype analysis identified rs1126616C-rs1126772A-rs9138A to be associated with an increased risk for asthma, severity of asthma, and asthma in subjects with elevated IgE (P = 0.03). There was no association between the SPP1 SNPs and asthma outcomes in Mexicans. Our findings suggest that the SPP1 gene is a risk factor for asthma and asthma-related phenotypes in Puerto Ricans, and are consistent with previous animal and human studies on the role of osteopontin in pathogenesis of asthma.

AB Objective: We evaluated how adolescents with or at risk of type 2 diabetes (T2DM) and their parent/guardians (parents) value health states associated with T2DM.
Methods: We interviewed overweight/obese [Body Mass Index (BMI) >= 85th percentile], 12-18-yr old adolescents with T2DM, prediabetes, or insulin resistance (IR) and a parent. The standard gamble (SG) method elicited preferences (utilities) for seven hypothetical T2DM health states reported on a scale from 0 (dead) to 1 (perfect health). Adolescent's current health was evaluated with the SG and Health Utilities Index (HUI).
Results: There were 70 adolescents and 69 parents. Adolescents were 67.1% female and 15.5 +/- 2.2 yr old; 30% had T2DM, 30% prediabetes, and 40% IR. Almost half (48.6%) had a BMI > 99th percentile. Parents (83% mothers) were 45.1 +/- 7.3 yr old and 75% had at least some college/technical school education. Adolescents and parents rated T2DM with no complications treated with diet as most desirable [median (IQR); adolescent 0.72 (0.54, 0.98); parent 1.0 (0.88, 1.0)] and end-stage renal disease as least desirable [adolescent 0.51 (0.31, 0.70); parent 0.80 (0.65, 0.94)]. However, adolescents' utilities were significantly lower (p <= 0.001) than parents for all health states assessed. Adolescents' assessments of their current health with the SG and HUI were not correlated.
Conclusions: Adolescents with or at risk of T2DM rated treatments and sequelae of diabetes as significantly worse than their parents. These adolescent utilities should be considered in the evaluation of treatment strategies for youth with T2DM. Family-based programs for T2DM must also be prepared to address conflicting preferences in order to promote shared decision-making.

AB OBJECTIVE: We compared associations of epilepsy remission status and severity as well as psychiatric and other comorbidities with child and parent-proxy reports of health-related quality of life (HRQoL) in adolescents previously diagnosed with epilepsy.
METHODS: In a prospective, community-based study of newly diagnosed childhood epilepsy, HRQoL of 277 children was assessed 8 to 9 years after diagnosis by using child and parent-proxy versions of the Child Health Questionnaire (CHQ). Multiple linear regression models adjusted for age and gender were used to compare associations of epilepsy remission and "complicated" epilepsy (secondary to an underlying neurologic insult or epileptic encephalopathy) status and psychiatric and other comorbidities with HRQoL.
RESULTS: Mean age of epilepsy onset was 4.4 years (SD: 2.6). At the 9-year reassessment, children were, on average, 13.0 years old (SD: 2.6); 64% were seizure-free for 5 years, 31% were taking antiepileptic drugs, and 19% had a complicated epilepsy. Prevalence of comorbidities at follow-up were 26% psychiatric diagnosis; 39% neurodevelopmental spectrum disorder (NDSD); 24% chronic medical illness; and 15% migraine. In multivariable analysis, having a psychiatric disorder was broadly associated with child (6 of 11 scales) and parent-proxy (7 of 12 scales) HRQoL (P <= .0125). Five-year remission and complicated epilepsy status had few or no associations with HRQoL. Although parent-proxy HRQoL was strongly associated with NDSD (6 of 11 scales), child-reported HRQoL was not (2 of 11 scales).
CONCLUSIONS: Psychiatric comorbidities are strongly associated with long-term HRQoL in childhood-onset epilepsy, which suggests that comprehensive epilepsy care must include screening and treatment for these conditions, even if seizures remit. Pediatrics 2011;128:e1532-e1543

AB OBJECTIVES: To describe (1) a cohort of children with paradoxical vocal-fold motion (PVFM) who were referred to a multidisciplinary airway center and (2) the outcomes of various treatment modalities including speech therapy, gastroesophageal reflux disease treatment, and psychiatric treatment.
PATIENTS AND METHODS: This was a case series with chart review of children younger than 18 years with PVFM evaluated at a tertiary care pediatric airway center over a 36-month period.
RESULTS: Fifty-nine children with PVFM were evaluated. The cohort had a mean age of 13.64 years (range: 8-18 years) and a female-to-male ratio of 3:1. Speech therapy as an initial treatment resulted in a 63% (24 of 38) success rate after an average of 3.7 treatment sessions. Speech therapy was a more successful treatment than antireflux therapy (P = .001). Ten percent (6 of 59) of the children presented with a known psychiatric diagnosis, and 30% (18 of 59) of children in the cohort were ultimately diagnosed with a psychiatric condition. Children with inspiratory stridor at rest had a lower initial success rate with speech therapy (56%), a higher rate of underlying psychiatric disorders (75%), and a high rate of success after psychiatric treatment (100%) that required, on average, 3 sessions over a 2-month period.
CONCLUSIONS: To our knowledge, this is the largest study to date on pediatric PVFM. The majority of children with PVFM improve with speech therapy. Children with PVFM at rest may be better treated with psychiatric therapy than speech therapy. Furthermore, children who present with symptoms at rest may have a higher likelihood of underlying psychiatric disease. Pediatrics 2011;128:e1443-e1449

AB BACKGROUND: The 2009 pandemic influenza A (H1N1) (pH1N1) virus continues to circulate worldwide. Determining the roles of chronic conditions and bacterial coinfection in mortality is difficult because of the limited data for children with pH1N1-related critical illness.
METHODS: We identified children (<21 years old) with confirmed or probable pH1N1 admitted to 35 US PICUs from April 15, 2009, through April 15, 2010. We collected data on demographics, baseline health, laboratory results, treatments, and outcomes.
RESULTS: Of 838 children with pH1N1 admitted to a PICU, the median age was 6 years, 58% were male, 70% had >= 1 chronic health condition, and 88.2% received oseltamivir (5.8% started before PICU admission). Most patients had respiratory failure with 564 (67.3%) receiving mechanical ventilation; 162 (19.3%) received vasopressors, and 75 (8.9%) died. Overall, 71 (8.5%) of the patients had a presumed diagnosis of early (within 72 hours after PICU admission) Staphylococcus aureus coinfection of the lung with 48% methicillin-resistant S aureus (MRSA). In multivariable analyses, preexisting neurologic conditions or immunosuppression, encephalitis (1.7% of cases), myocarditis (1.4% of cases), early presumed MRSA lung coinfection, and female gender were mortality risk factors. Among 251 previously healthy children, only early presumed MRSA coinfection of the lung (relative risk: 8 [95% confidence interval: 3.1-20.6]; P < .0001) remained a mortality risk factor.
CONCLUSIONS: Children with preexisting neurologic conditions and immune compromise were at increased risk of pH1N1-associated death after PICU admission. Secondary complications of pH1N1, including myocarditis, encephalitis, and clinical diagnosis of early presumed MRSA coinfection of the lung, were mortality risk factors.

AB Objectives After completing this article, readers should be able to:
1. Identify behaviors in an adolescent that suggest an underlying eating disorder.
2. Recognize the physical findings that can be seen in patients who have an eating disorder.
3. Understand the medical complications seen in teens who have anorexia and bulimia.
4. Be informed about the types of therapies available for adolescents who have anorexia and bulimia.
5. Know the definition of the female athlete triad.
A 15-year-old girl is admitted to the pediatric intensive care unit with a long history of weight loss and a serum sodium concentration of 189 mmol/L. She has been following a meal plan to gain weight and recently has stopped running 5 miles a day. Her fluid intake is approximately 16 oz of water a day. She denies fear of weight gain and body image disturbances, and a symptom review is negative. Physical examination reveals an alert and cooperative adolescent girl. Weight is 68 lb (<< 3%); height, 62.75 in (34%); body mass index (BMI), 12.14 (<< 3%); blood pressure, 113/74 mm Hg; heart beat, 67 beats/minute; and axillary temperature, 36 C. She has no signs of pubertal development and is mildly dehydrated. After extensive evaluation, she is determined to have an underlying eating disorder with no primary medical diagnosis. She is discharged from the hospital on day 16 without any complications, with follow-up care by an adolescent medicine specialist and therapist.

AB Objective: To identify risk factors for adverse psychological outcomes among adult siblings of long-term survivors of childhood cancer.
Methods: Cross-sectional, self-report data from 3083 adult siblings (mean age 29 years, range 18-56 years) of 5+year survivors of childhood cancer were analyzed to assess psychological outcomes as measured by the Brief Symptom Inventory-18 (BSI-18). Socio-demographic and health data, reported by both the siblings and their matched cancer survivors, were explored as risk factors for adverse sibling psychological outcomes through multivariable logistic regression.
Results: Self-reported symptoms of psychological distress, as measured by the global severity index of the BSI-18, were reported by 3.8% of the sibling sample. Less than 1.5% of siblings reported elevated scores on two or more of the subscales of the BSI-18. Risk factors for sibling depression included having a survivor brother (OR 2.22, 95% CI 1.42-3.55), and having a survivor with impaired general health (OR 2.15, 95% CI 1.18-3.78). Siblings who were younger than the survivor reported increased global psychological distress (OR 1.81, 95% CI 1.05-3.12), as did siblings of survivors reporting global psychological distress (OR 2.32, 95% CI 1.08-4.59). Siblings of sarcoma survivors reported more somatization than did siblings of leukemia survivors (OR 2.07, 95% CI 1.05-3.98).
Conclusions: These findings suggest that siblings of long-term childhood cancer survivors are psychologically healthy in general. There are, however, small subgroups of siblings at risk for long-term psychological impairment who may benefit from preventive risk-reduction strategies during childhood while their sibling with cancer is undergoing treatment.

AB This study evaluated the psychometric characteristics of the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1996) in 280 individuals who screened positive for posttraumatic stress disorder (PTSD). The SNAP validity, trait, temperament, and personality disorder (PD) scales were compared with scales on the Brief Form of the Multidimensional Personality Questionnaire (Patrick, Curtin, & Tellegen, 2002). In a subsample of 86 veterans, the SNAP PD, trait, and temperament scales were also evaluated in comparison to the International Personality Disorder Examination (IPDE; Loranger, 1999), a semistructured diagnostic interview. Results revealed that the SNAP scales have good convergent validity, as evidenced by their pattern of associations with related measures of personality and PD. However, evidence for their discriminant validity in relationship to other measures of personality and PD was more mixed, and test scores on the SNAP trait and temperament scales left much unexplained variance in IPDE-assessed PDs. The diagnostic scoring of the SNAP PD scales greatly inflated prevalence estimates of PDs relative to the IPDE and showed poor agreement with the IPDE. In contrast, the dimensional SNAP scores yielded far stronger associations with continuous scores on the IPDE. The SNAP scales also largely evidenced expected patterns of association with a measure of PTSD severity. Overall, findings support the use of this measure in this population and contribute to our conceptualization of the association between temperament, PTSD, and Axis II psychopathology.

AB Adequate participant recruitment is critical for the successful execution of research studies involving human subjects. Participant recruitment can be particularly challenging when the intended study participants are health care providers as opposed to patients. Discussions of the challenges and successful strategies associated with provider recruitment are limited, particularly regarding providers other than physicians and settings outside of primary care. Using a case study format, we present our experiences recruiting inpatient nurses into a study which involved focus group methodology at a United States Veterans Health Administration facility. We describe the initial logistical and ethical issues involved, various challenges we encountered, and five successful action strategies used during a second recruitment wave addressing logistical issues; on-site recruitment; increased scheduling flexibility and peer-to-peer recruitment; attention to the sensitive nature of the research topic; and increased involvement of stakeholders. In conclusion, we advocate for multimodal recruitment strategies that facilitate ongoing investigator-clinician partnerships.

AB OBJECTIVE: As background for the American Association for Respiratory Care (AARC) third 2015 and Beyond conference, we sought information and opinions on the ability of the current respiratory therapy education infrastructure to make changes that would assure competent respiratory therapists in the envisioned healthcare future. METHODS: After pilot testing and refining the questions, we invited the directors of 435 respiratory therapy programs (based in 411 colleges) that were fully accredited or in the process of being accredited by the Commission on Accreditation for Respiratory Care as of May, 2010, to participate in the survey. RESULTS: Three-hundred forty-eight program directors (80%) provided valid survey responses. Three of the 5 competencies related to evidence-based medicine and respiratory care protocols were taught less often in the associate-degree programs than in the baccalaureate-degree programs. Eighty percent of the baccalaureate-degree programs, compared to 42% of the associate-degree programs, instruct students how to critique published research (P < .001). Only 34% of the associate-degree programs teach students the general meaning of statistical tests, compared to 78% of the baccalaureate-degree programs (P < .001). Ninety-four percent of the baccalaureate-degree programs, versus 81% of the associate-degree programs, teach the students to apply evidence-based medicine to clinical practice (P = .01). Teaching students how to describe healthcare and financial reimbursement systems and the need to reduce the cost of delivering respiratory care (a leadership competency identified by the second 2015 and Beyond conference) was significantly more common in the baccalaureate-degree programs (72%) than in the associate-degree programs (56%) (P = .03). Other competencies showed trends toward differences, and the baccalaureate-degree programs reported higher percentages of success than the associate-degree programs. CONCLUSIONS: There are important differences between the baccalaureate-degree and associate-degree programs.

AB Low-tidal-volume ventilation reduces mortality in patients with ARDS, but there are often challenges in implementing lung-protective ventilation, such as acidosis from hypercapnia. In a patient with severe ARDS we achieved adequate ventilation with a very low tidal volume (4 mL/kg ideal body weight) by inducing mild hypothermia (body temperature 35-36 degrees C).

AB Objectives: Reports of an association between antineutrophil cytoplasmic antibodies (ANCA) and autoimmune neutropenia have rarely included cases of proven vasculitis. A case of ANCA-associated vasculitis (AAV) with recurrent neutropenia is described and relevant literature on the association between ANCA, neutropenia, and vasculitis is reviewed.
Methods: Longitudinal clinical assessments and laboratory findings are described in a patient with AAV and recurrent episodes of profound neutropenia from December 2008 to October 2010. A PubMed database search of the medical literature was performed for articles published from 1960 through October 2010 to identify all reported cases of ANCA and neutropenia.
Results: A 49-year-old man developed recurrent neutropenia, periodic fevers, arthritis, biopsyproven cutaneous vasculitis, sensorineural hearing loss, epididymitis, and positive tests for ANCA with specificity for antibodies to both proteinase 3 and myeloperoxidase. Antineutrophil membrane antibodies were detected during an acute neutropenic phase and were not detectable in a postrecovery sample, whereas ANCA titers did not seem to correlate with neutropenia. An association between ANCA and neutropenia has been reported in 74 cases from 24 studies in the context of drug/toxin exposure, underlying autoimmune disease, or chronic neutropenia without underlying autoimmune disease. In these cases, the presence of atypical ANCA patterns and other antibodies were common; however, vasculitis was uncommon and when it occurred was usually limited to the skin and in cases of underlying toxin exposure.
Conclusions: ANCA is associated with autoimmune neutropenia, but systemic vasculitis rarely occurs in association with ANCA and neutropenia. The interaction between neutrophils and ANCA may provide insight into understanding both autoimmune neutropenia and AAV. (C) 2011 Elsevier Inc. All rights reserved. Semin Arthritis Rheum 41:424-433

AB HIV/AIDS and food insecurity are two of the leading causes of morbidity and mortality in sub-Saharan Africa, with each heightening the vulnerability to, and worsening the severity of, the other. Less research has focused on the social determinants of food insecurity in resource-limited settings, including social support and HIV-related stigma. In this study, we analyzed data from a cohort of 456 persons from the Uganda AIDS Rural Treatment Outcomes study, an ongoing prospective cohort of persons living with HIV/AIDS (PLWHA) initiating HIV antiretroviral therapy in Mbarara, Uganda. Quarterly data were collected by structured interviews. The primary outcome, food insecurity, was measured with the Household Food Insecurity Access Scale. Key covariates of interest included social support, internalized HIV-related stigma, HIV-related enacted stigma, and disclosure of HIV serostatus. Severe food insecurity was highly prevalent overall (38%) and more prevalent among women than among men. Social support, HIV disclosure, and internalized HIV-related stigma were associated with food insecurity; these associations persisted after adjusting for household wealth, employment status, and other previously identified correlates of food insecurity. The adverse effects of internalized stigma persisted in a lagged specification, and the beneficial effect of social support further persisted after the inclusion of fixed effects. International organizations have increasingly advocated for addressing food insecurity as part of HIV/AIDS programming to improve morbidity and mortality. This study provides quantitative evidence on social determinants of food insecurity among PLWHA in resource-limited settings and suggests points of intervention. These findings also indicate that structural interventions to improve social support and/or decrease HIV-related stigma may also improve the food security of PLWHA. (C) 2011 Elsevier Ltd.

AB Background. Necroptosis is a recently described mechanism of programmed cellular death. We hypothesize that necroptosis plays an important role in radiation-induced cell death in endocrine cancers.
Methods. Thyroid and adrenocortical carcinoma cell lines were exposed to increasing doses of radiation in the presence of necroptosis inhibitor Nec-1 and/or apoptosis-inhibitor zVAD. H295R cells deficient in receptor interacting protein 1 (RIP1), an essential kinase for necroptosis, were used as controls. Survival curves were generated at increasing doses of radiation.
Results. Nec-1 and zVAD increased cellular survival with increasing doses of radiotherapy in 8505c, TPC-1, and SW13. Both inhibitors used together had an additive effect. At 6 Gy, 8505c, TPC-1, and SW13 cell survival was significantly increased compared to controls by 40%; 33%, and 31% with Nec-1 treatment, by 53%, 47%, and 44% with zVAD treatment, and by 80%, 70%, and 65% with both compounds, respectively (P < .05). H295R showed no change in survival with Nec-1 treatment. The radiobiologic parameter quasithreshold dose was significantly increased in 8505c, TPC-1, and SW13 cells when both Nec-1 and WAD were used in combination to inhibit necroptosis and apoptosis together, revealing resistance to standard doses of fractionated therapeutic radiation.
Conclusion. Necroptosis contributes to radiation-induced cell death. Future studies should investigate ways to promote the activation of necroptosis to improve radiosensitivity. (Surgery 2011;150:1032-9.)

AB Background. The optimal initial operative management of medullary thyroid cancer (MTC) and the use of biomarkers to guide the extent of operation remain controversial. We hypothesized that preoperative serum levels of calcitonin and carcinoembryonic antigen (CEA) correlate with extent of disease and postoperative levels reflect the extent of operation performed.
Methods. We assessed retrospectively clinical and pathologic factors among patients with MTC undergoing at least total thyroidectomy; these factors were correlated with biomarkers using regression analyses.
Results. Data were obtained from 104 patients, 28% with hereditary MTC. Preoperative calcitonin correlated with tumor size (P < .001) and postoperative serum calcitonin levels (P = .01) after multivariable adjustment for lymph node positivity, extent of operation, and hereditary MTC. No patient with a preoperative calcitonin level of <53 pg/ml (n = 20) had lymph node metastases. TNM stage (P = .001) and preoperative calcitonin levels (P = .04), but not extent of operation, independently correlated with the failure to normalize postoperative calcitonin. Postoperative CEA correlated with positive margins (adjusted P = 04). Neither preoperative nor postoperative CEA was correlated with lymph node positivity or extent of surgery.
Conclusion. Preoperative serum calcitonin and TMN stage, but not extent of operation, were independent predictors of postoperative normalization of serum calcitonin levels. Future studies should evaluate preoperative serum calcitonin levels as a determinate of the extent of initial operation. (Surgery 2011; 150:1168-77.)

AB Background: Hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) is associated with morbid, invasive infections and has been implicated in nearly every type of nosocomial infection. Our aim was to identify the risk factors for patient conversion from MRSA negativity pre-operatively to MRSA positivity post-operatively.
Methods: We retrospectively reviewed all patients at the Veterans Affairs-Boston Health Care System who underwent clean or clean-contaminated surgical procedures during the years 2008 and 2009 and had documented pre-operative nasal polymerase chain reaction (PCR) testing for MRSA. We abstracted post-operative MRSA microbiologic testing results, MRSA infections, surgical site infections (SSIs), surgical prophylaxis data, and SSI risk index, as calculated using the Veterans Affairs Surgical Quality Improvement Project (VASQIP) database variables. All patients who had a negative nasal MRSA PCR result in the 31-day pre-operative period and did not have any positive MRSA clinical swab or culture in the 1-year pre-operative period were defined as MRSA-negative. These patients were classified as converters to MRSA positivity if they had at least one documented positive nasal MRSA PCR swab, culture, nosocomial infection, or SSI within 31 days post-operatively.
Results: Among 4,238 eligible patients, 3,890 (92%) qualified as MRSA-negative pre-operatively. A total of 1,432 (37%) of these patients were assessed in the VASQIP database, of whom 34 (2%) converted to MRSA positivity post-operatively. On multivariable logistic regression analysis of the VASQIP sample, age (odds ratio [OR] 1.049; 95% confidence interval [CI] 1.016, 1.083), SSI risk index (OR 2.863; 95% CI 1.251-6.554), and vancomycin prophylaxis alone or in combination (OR 3.223; 95% CI 1.174-8.845) were significantly associated with conversion to MRSA positivity.
Conclusion: In pre-operatively MRSA-negative patients, age, SSI risk index, and vancomycin prophylaxis were significant factors for conversion to MRSA positivity post-operatively. Alternatives to vancomycin prophylaxis in non-colonized patients and optimization of patients' SSI risk factors should be considered before elective surgery.

AB BAX, the BCL-2-associated X protein, is a cardinal proapoptotic member of the BCL-2 family, which regulates the critical balance between cellular life and death. Because so many medical conditions can be categorized as diseases of either too many or too few cells, dissecting the biochemistry of BCL-2 family proteins and developing pharmacological strategies to target them have become high priority scientific objectives. Here, we focus on BAX, a latent, cytosolic and monomeric protein that transforms into a lethal mitochondrial oligomer in response to cellular stress. New insights into the structural location of BAX's 'on switch', and the multi-step conformational changes that ensue upon BAX activation, are providing fresh opportunities to modulate BAX for potential benefit in human diseases characterized by pathologic cell survival or unwanted cellular demise.

AB Background Although Hispanics constitute the largest minority in the United States, it is unknown whether regional differences in quality of care and outcomes exist among Hispanic patients hospitalized with acute myocardial infarction (MI).
Methods Using the GWTG-CAD Registry, clinical characteristics, conformity with quality measures, and in-hospital outcomes were assessed among Hispanic patients from different geographic regions admitted for acute MI in participating hospitals.
Results A total of 11,299 Hispanic patients treated for acute MI at 277 hospitals from 4 regions were included in the study. Midwestern Hispanics were more likely to be younger, with male predominance in all regions. Northeastern Hispanics were more often insured with Medicaid. All subgroups showed high rates of hypertension, dyslipidemia, diabetes, and smoking, with the highest rates observed in the northeast region. Northeastern Hispanics were more likely to be discharged on angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers, and statin or other lipid-lowering therapy. No significant regional differences were observed in aspirin, clopidogrel, and guideline-recommended door-to-balloon and door-to-thrombolysis times. Although Hispanics in the south and northeast were more likely to have a longer hospital stay compared with the west, there were no regional differences in in-hospital mortality.
Conclusions Among Hispanics with acute MI enrolled in the GWTG-CAD program, there were modest regional differences in clinical profile; high rates of use and, with few exceptions, no regional differences in guideline-recommended therapies; and no regional variation in in-hospital mortality.

DISCHARGE; PRIMARY ANGIOPLASTY; COST-EFFECTIVENESS; MORTALITY; OUTCOMES
AB Background Post hoc analyses of clinical trials suggest that certain patients are eligible for early discharge after ST-segment elevation myocardial infarction. The extent to which ST-segment elevation myocardial infarction patients are discharged early after primary percutaneous coronary intervention (PPCI) in current practice is unknown.
Methods We examined 115,113 patients in the CathPCI Registry to assess temporal trends in length of stay (LOS) after PPCI. Baseline characteristics were compared between patients with LOS <= 2 and >2 days. Predictors of LOS >2 days were determined by logistic regression and adjusted for clustering among centers. Patterns of discharge within 2 days for low-risk patients with no inhospital complications were examined.
Results From January 2005 through March 2009, mean LOS (4.0 +/- 3.0 to 3.6 +/- 2.7 days) (P for trend <.001) and the proportion of patients discharged after 2 days decreased (72.0%-65.9%), while predicted inhospital mortality risk remained unchanged. Patients with LOS >2 days (n = 77,471; 67.3%) were older and more likely to have had an intra-aortic balloon pump, cardiogenic shock, transfusions, and post-PPCI complications. Of 958 hospitals, 437 (45.6%) discharged at least half of their low-risk patients with no inhospital complications within 2 days.
Conclusions While the predicted risk profile has remained stable, there has been a significant decrease in LOS after PPCI. Nevertheless, hospitals vary in discharging low-risk and uncomplicated patients early. Discharge within 2 days was associated with specific patient, procedure, and hospital factors. Further study is needed to determine the safety of early discharge among patients undergoing PPCI. (Am Heart J 2011;162:1052-61.)

AB Objectives: Depression in older adults is often undertreated due, in part, to medication costs. We examined the impact of improved prescription drug coverage under Medicare Part D on use of antidepressants, medication choice, and adherence.
Design, Setting and Participants: Observational claims-based study of older adults with depression (ICD-9: 296.2, 296.3, 311, 300.4) continuously enrolled in a Medicare managed care plan between 2004 and 2007. Three groups with limited ($ 150 or $ 350 quarterly caps) or no drug coverage in 2004-2005 obtained Part D benefits in 2006. A comparison group had stable employer-sponsored coverage throughout.
Measurements: Any antidepressant prescription fill, antidepressant choice (tricyclics or monoamine oxidase inhibitors versus newer antidepressants), and adherence (80% of days covered) in the first 6 months of treatment. Results: Part D was associated with increased odds of any antidepressant use among those who previously lacked coverage (odds ratio [OR] 1.61, 95% confidence interval [CI] 1.41-1.85) but odds of use did not change among those with limited prior coverage. Use of older antidepressant agents did not change with Part D. All three groups whose coverage improved with Part D had significantly higher odds of 80% of days covered with an antidepressant (OR = 1.86 [95% CI: 1.44-2.39] for no coverage, 1.74 [95% CI: 1.25% 3.42] for $ 150 cap; and 1.19 [95% CI: 1.06-1.34] for the $ 350 cap groups).
Conclusions: Medicare Part D was associated with improvements in antidepressant use and adherence in depressed older adults who previously had no or limited drug coverage but not with changes in use of older agents. use and adherence in depressed older adults who previously had no or limited drug coverage but not with changes in use of older agents.

AB Objective: To empirically assess the concept that Alzheimer disease (AD) biomarkers significantly depart from normality in a temporally ordered manner.
Design: Validation sample.
Setting: Multisite, referral centers.
Participants: A total of 401 elderly participants in the Alzheimer's Disease Neuroimaging Initiative who were cognitively normal, who had mild cognitive impairment, or who had AD dementia. We compared the proportions of 3 AD biomarker values (the A beta 42 level in cerebrospinal fluid [CSF], the total tau level in CSF, and the hippocampal volume adjusted for intracranial volume [hereafter referred to as the adjusted hippocampal volume]) that were abnormal as cognitive impairment worsened. Cut points demarcating normal vs abnormal for each biomarker were established by maximizing diagnostic accuracy in independent autopsy samples.
Main Outcome Measures: Three AD biomarkers (ie, the CSF A beta 42 level, the CSF total tau level, and the adjusted hippocampal volume).
Results: Within each clinical group of the entire sample (n=401), the CSF A beta 42 level was abnormal more often than was the CSF total tau level or the adjusted hippocampal volume. Among the 298 participants with both baseline and 12-month data, the proportion of participants with an abnormal A beta 42 level did not change from baseline to 12 months in any group. The proportion of participants with an abnormal total tau level increased from baseline to 12 months in cognitively normal participants (P=.05) but not in participants with mild cognitive impairment or AD dementia. For 209 participants with an abnormal CSF A beta 42 level at baseline, the percentage with an abnormal adjusted hippocampal volume but normal CSF total tau level increased from baseline to 12 months in participants with mild cognitive impairment. No change in the percentage of MCI participants with an abnormal total tau level was seen between baseline and 12 months.
Conclusions: A reduction in the CSF A beta 42 level denotes a pathophysiological process that significantly departs from normality (ie, becomes dynamic) early, whereas the CSF total tau level and the adjusted hippocampal volume are biomarkers of downstream pathophysiological processes. The CSF total tau level becomes dynamic before the adjusted hippocampal volume, but the hippocampal volume is more dynamic in the clinically symptomatic mild cognitive impairment and AD dementia phases of the disease than is the CSF total tau level.

AB Objective: To assess regions and patterns of brain atrophy in patients with Parkinson disease (PD) with normal cognition (PD-NC), mild cognitive impairment (PD-MCI), and dementia-level cognitive deficits (PDD).
Design: Images were quantified using a region-ofinterest approach and voxel-based morphometry analysis. We used a high-dimensional pattern classification approach to delineate brain regions that collectively formed the Spatial Pattern of Abnormalities for Recognition of PDD.
Setting: The Parkinson's Disease and Movement Disorders Center at the University of Pennsylvania.
Subjects: Eighty-four PD patients (61 PD-NC, 12 PD-MCI, and 11 PDD) and 23 healthy control subjects (HCs) underwent magnetic resonance imaging of the brain.
Results: The PD-NC patients did not demonstrate significant brain atrophy compared with HCs. Compared with PD-NC patients, PD-MCI patients had hippocam-pal atrophy (beta=-0.37; P=.001), and PDD patients demonstrated hippocampal (beta=-0.32; P=.004) and additional medial temporal lobe atrophy (beta=-0.36; P=.003). The PD-MCI patients had a different pattern of atrophy compared with PD-NC patients (P=.04) and a similar pattern to that of PDD patients (P=.81), characterized by hippocampal, prefrontal cortex gray and white matter, occipital lobe gray and white matter, and parietal lobe white matter atrophy. In nondemented PD patients, there was a correlation between memory-encoding performance and hippocampal volume.
Conclusions: Hippocampal atrophy is a biomarker of initial cognitive decline in PD, including impaired memory encoding and storage, suggesting heterogeneity in the neural substrate of memory impairment. Use of a pattern classification approach may allow identification of diffuse regions of cortical gray and white matter atrophy early in the course of cognitive decline.

AB Inflammation and angiogenesis in the tumor microenvironment are increasingly implicated in tumorigenesis. Endogenously produced lipid autacoids, locally acting small-molecule mediators, play a central role in inflammation and tissue homeostasis. These lipid mediators, collectively referred to as eicosanoids, have recently been implicated in cancer. Although eicosanoids, including prostaglandins and leukotrienes, are best known as products of arachidonic acid metabolism by cyclooxygenases and lipoxygenases, arachidonic acid is also a substrate for another enzymatic pathway, the cytochrome P450 (CYP) system. This eicosanoid pathway consists of two main branches: omega-hydroxylases which converts arachidonic acid to hydroxyeicosatetraenoic acids (HETEs) and epoxygenases which converts it to four regioisomeric epoxyeicosatrienoic acids (EETs; 5,6-EET, 8,9-EET, 11,12-EET, and 14,15-EET). EETs regulate inflammation and vascular tone. The bioactive EETs are produced predominantly in the endothelium and are mainly metabolized by soluble epoxide hydrolase to less active dihydroxyeicosatrienoic acids. EET signaling was originally studied in conjunction with inflammatory and cardiovascular disease. Arachidonic acid and its metabolites have recently stimulated great interest in cancer biology. To date, most research on eicosanoids in cancer has focused on the COX and LOX pathways. In contrast, the role of cytochrome P450-derived eicosanoids, such as EETs and HETEs, in cancer has received little attention. While CYP epoxygenases are expressed in human cancers and promote human cancer metastasis, the role of EETs (the direct products of CYP epoxygenases) in cancer remains poorly characterized. In this review, the emerging role of EET signaling in angiogenesis, inflammation, and cancer is discussed.

AB The innate immune system is evolutionarily ancient and biologically primitive. Historically, it was first identified as an element of the immune system that provides the first-line response to pathogens, and increasingly it is recognized for its central housekeeping role and its essential functions in tissue homeostasis, including coagulation and inflammation, among others. A pivotal link between the innate immune system and other functions is mannose-binding lectin (MBL), a pattern recognition molecule. Multiple studies have demonstrated that MBL deficiency increases susceptibility to infection, and the mechanisms associated with this susceptibility to infection include reduced opsonophagocytic killing and reduced activation of the lectin complement pathway. Results from our laboratory have demonstrated that MBL and MBL-associated serine protease (MASP)-1/3 together mediate coagulation factor-like activities, including thrombin-like activity. MBL and/or MASP-1/3-deficient hosts demonstrate in vivo evidence that MBL and MASP-1/3 are involved with hemostasis following injury. Staphylococcus aureus-infected MBL null mice developed disseminated intravascular coagulation, which was associated with elevated blood IL-6 levels (but not TNF-alpha) and systemic inflammatory responses. Infected MBL null mice also develop liver injury. These findings suggest that MBL deficiency may manifest as disseminated intravascular coagulation and organ failure with infection. Beginning from these observations, this review focuses on the interaction of innate immunity and other homeostatic systems, the derangement of which may lead to complications in infection and other inflammatory states.

SO GASTROINTESTINAL ENDOSCOPY
LA English
DT Article
ID PAIN; MANAGEMENT; BLOCK
AB Background: The technique of alcohol injection during EUS-guided celiac plexus neurolysis (CPN) in patients with pancreatic cancer-related pain has not been standardized.
Objective: To compare pain relief and safety of alcohol given as 1 versus 2 injections during EUS-guided CPN (EUS-CPN). Secondary outcomes examined were characteristics that predict response and survival.
Design: Single-blinded, prospective, randomized, parallel-group study.
Setting: Tertiary-care center.
Patients: This study involved patients with pancreatic cancer-related pain.
Intervention: EUS-CPN done by injecting 20 mL of 0.75% bupivacaine and 10 mL 98% alcohol into 1 or 2 sites at the celiac trunk. Participants were interviewed by telephone at 24 hours and weekly thereafter.
Main Outcome Measurements: Time until onset of pain relief, duration of pain relief, complications.
Results: Fifty patients (mean age 63 years; 24 men) were enrolled and randomized (29 in 1-injection, 21 in 2-injections groups). Pain relief was observed in 37 (74%) patients: 20 (69%) in the 1-injection group and 17 (81%) in the 2-injection group (chi-square P = .340). Median onset of pain relief was 1 day for both 1-injection (range 1-28 days) and 2-injection (range 1-21 days) groups (Mann-Whitney P = .943). Median duration of pain relief in the 1-injection and 2-injection groups was 11 weeks and 14 weeks, respectively (log-rank P = .612). Complete pain relief was observed in 4 (8%) patients total, 2 in each group. There were no long-term complications.
Limitations: Single-blinded study.
Conclusion: There were no differences in onset or duration of pain relief when either 1 or 2 injections were used. There was no difference in safety or survival between the 2 groups. (Clinical trial registration number: NCT00583479.) (Gastrointest Endosc 2011;74:1300-7.)

AB Objectives. To evaluate the impact of a 2008 Medicaid policy in Massachusetts (MA), regarding reimbursing physicians for providing fluoride varnish (FV) to eligible children in medical settings.
Data Source. Survey of a sample of primary care physicians in MA.
Study Design. Cross-sectional survey of a sample of physicians who provide care to MassHealth (MA Medicaid) enrolled-children. Dependent variables: history of completed preventive dental skills training, and FV provision. Independent variables: oral health knowledge, FV-attitudes, and physician and practice characteristics.
Principal Findings. Overall, 19 percent of respondents had completed the training required to be eligible to bill for FV provision. Only 5 percent of physicians were providing FV. Most respondents (63 percent) were not familiar with the new policy, and only 25 percent felt that FV should be provided during well-child visits. Most physicians (60 percent) did not feel that the reimbursement rate of U. S.$26/application was sufficient; 17 percent said that they would not provide FV, regardless of payment. Most common barriers to FV provision were a lack of time and logistical challenges.
Conclusions. Our findings suggest that simply reimbursing physicians for FV provision is insufficient to ensure provider participation. Success of this policy will likely require addressing several barriers identified.

AB Objectives. To compare changes in medication adherence between patients with high- or low-comorbidity burden after a copayment increase.
Methods. We conducted a retrospective observational study at four Veterans Affairs (VA) medical centers by comparing veterans with hypertension or diabetes required to pay copayments with propensity score-matched veterans exempt from copayments. Disease cohorts were stratified by Diagnostic Cost Group risk score: low-(<1) and high-comorbidity (>1) burden. Medication adherence from February 2001 to December 2003, constructed from VA pharmacy claims data based on the ReComp algorithm, were assessed using generalized estimating equations.
Results. Veterans with lower comorbidity were more responsive to a U.S.$5 copayment increase than higher comorbidity veterans. In the lower comorbidity groups, veterans with diabetes had a greater reduction in adherence than veterans with hypertension. Adherence trends were similar for copayment-exempt and nonexempt veterans with higher comorbidity.
Conclusion. Medication copayment increases are associated with different impacts for low- and high-risk patients. High-risk patients incur greater out-of-pocket costs from continued adherence, while low- risk patients put themselves at increased risk for adverse health events due to greater nonadherence.

AB BACKGROUND The delivery of radiofrequency (RF) energy to the posterior left atrium creates a risk of injury to the adjacent esophagus. Esophageal endoscopy (EGD) is used to screen patients at risk for esophageal thermal injury after RF ablation.
OBJECTIVE The purpose of this study was to analyze the macroscopic features of the severity of esophageal injuries induced by RF ablation to the left atrium as seen by EGD and evaluate the association of these descriptions with the time elapsed until complete healing.
METHODS This study analyzed 219 patients undergoing RF ablation for atrial fibrillation. Esophageal temperature probes were used during each ablation, and EGD was performed in cases with intraesophageal temperature >= 39 degrees C. Repeat EGD was obtained at 10 days to evaluate for healing in all cases demonstrating esophageal injury. Serial endoscopies were repeated every 2 weeks until complete healing was documented. Lesions were classified according to severity as superficial or deep ulceration; size and shape were also noted.
RESULTS We found 37.4% of patients (82 of 219) with esophageal intraluminal temperatures >= 39 degrees C. Of these, 22 patients (27%) were identified with esophageal injury, with 68% being superficial ulcerations and 32% deep. On repeat EGD at 10 days, only 29% of deep ulcerations were healed, as compared with 87% of the superficial injuries (P = .0136). No difference in healing was found when analyzed for size or shape.
CONCLUSIONS The macroscopic severity of esophageal lesions detected on endoscopy the day after RF ablation can predict the time to resolution, with severe, deep ulcerations requiring a longer time to heal.

AB BACKGROUND Implantable cardioverter-defibrillator (ICD) shocks are associated with an increased risk of death. It is unclear whether ICD shocks are detrimental per se or a marker of higher risk patients.
OBJECTIVE We aimed to assess the association between ICD shocks and time to death after correction for baseline mortality based on the Seattle Heart Failure Model (SHFM).
METHODS The primary analysis compared time-to-death between patients receiving no shocks and patients receiving shocks of any type adjusted for SHFM score at time of implantation and other comorbidities. Subgroup analyses were performed to further describe the relationship between shocks and mortality risk.
RESULTS Over a median follow-up of 41 months (interquartile range 23-64), one or more shock episodes occurred in 59% of 425 patients and 40% of the patients died. Patients receiving shocks of any type had increased risk of death (hazard ratio 1.55; 95% confidence interval 1.07-2.23; P = .02) versus patients receiving no shocks. While patients with 1-5 days with shock (shock days) did not show evidence of increased risk of death (1.30 [0.88-.94]; P = 0.19), those with 6-10 shock days (2.22 [1.21-4.08]; P <.01) and >10 shock days (3.66 [1.86 -7.19]; P <.01) had increasingly higher risk. There was no increased hazard for death (0.73 [0.34 -1.57]; P = .41) in patients treated only with antitachycardia pacing (ATP).
CONCLUSION ICD shocks were associated with increased mortality risk after adjustment for SHFM-predicted mortality, and the burden of shocks played a role in this association. ATP did not increase mortality risk, suggesting that shocks may themselves be detrimental.

AB Crizotinib was recently approved by the US FDA for the treatment of advanced non-small cell lung cancer (NSCLC) harboring the ALK (anaplastic lymphoma kinase) gene rearrangement. To ensure identification of patients most likely to benefit, the FDA approved crizotinib concurrently with a companion diagnostic test-the Vysis ALK Break Apart FISH Probe Kit. This kit was used in 1 of the 2 pivotal trials leading to the FDA approval of crizotinib and has become the gold standard for detecting ALK rearrangement in NSCLC. Although ALK FISH is clinically validated, the assay can be technically challenging and costly. Therefore, other diagnostic modalities are being explored, including immunohistochemistry (IHC) and reverse transcriptase-polymerase chain reaction. This article provides an overview of the diagnostic assays available for detecting ALK rearrangement. Each assay, including ALK FISH, has its strengths and weaknesses. Recent work with commercially available ALK antibodies suggests that IHC-based tests may represent a reliable and cost-effective screening strategy; however, large multicenter studies comparing IHC with FISH are needed to validate ALK IHC. While ALK FISH remains the current standard for diagnosing ALK positivity, large-scale screening of patients with newly diagnosed advanced NSCLC, as recommended by NCCN, may require development and validation of alternative screening strategies, such as combination IHC and FISH.

AB During the past several years, one of the most interesting and challenging issues in endocrine genetics is determining how to integrate the findings and approaches traditionally used to understand the powerful, single-gene mutations causing endocrine syndromes with those newer techniques used to dissect the complex genetic architecture of polygenic conditions. With this overriding consideration in mind, it makes sense to begin these considerations with recent novel findings derived from the study of a particularly prismatic monogenic disorder, isolated GnRH deficiency, in defining an area of neuroendocrinology and development. Careful study of this human disease model has been employed successfully by several groups to provide unique windows through which to gain an improved understanding of the challenging issues of the developmental biology of the GnRH neurons where previous nonhuman approaches have had significant technical limitations. For example, study of this disorder has provided the field of neuroendocrinology with several unique insights into the surprising origins and early development of the GnRH neuronal network. Its associated clinical phenotypes have helped to unearth a growing list of genes responsible for GnRH neuronal specification, migration, and neuroendocrine function. Finally, this human genetic model is beginning to provide increasing evidence of interactions between these single genes, clearly demonstrating that an oligogenic genetic architecture underlies this condition.

AB We recently reported that IGF-II binding to the IGF-II/mannose-6-phosphate (M6P) receptor activates the ERK1/2 cascade by triggering sphingosine kinase 1 (SK1)-dependent transactivation of G protein-coupled sphingosine 1-phosphate (S1P) receptors. Here, we investigated the mechanism of IGF-II/M6P receptor-dependent sphingosine kinase 1 (SK1) activation in human embryonic kidney 293 cells. Pretreating cells with protein kinase C (PKC) inhibitor, bisindolylmaleimide-I, abolished IGF-II-stimulated translocation of green fluorescent protein (GFP)-tagged SK1 to the plasma membrane and activation of endogenous SK1, implicating PKC as an upstream regulator of SK1. Using confocal microscopy to examine membrane translocation of GFP-tagged PKC alpha, beta 1, beta 2, delta, and zeta, we found that IGF-II induced rapid, transient, and isoform-specific translocation of GFP-PKC beta 2 to the plasma membrane. Immunoblotting of endogenous PKC phosphorylation confirmed PKC beta 2 activation in response to IGF-II. Similarly, IGF-II stimulation caused persistent membrane translocation of the kinase-deficient GFP-PKC beta 2 (K371R) mutant, which does not dissociate from the membrane after translocation. IGF-II stimulation increased diacylglycerol (DAG) levels, the established activator of classical PKC. Interestingly, the polyunsaturated fraction of DAG was increased, indicating involvement of phosphatidyl inositol/phospholipase C (PLC). Pretreating cells with the PLC inhibitor, U73122, attenuated IGF-II-dependent DAG production and PKC beta 2 phosphorylation, blocked membrane translocation of the kinase-deficient GFP-PKC beta 2 (K371R) mutant, and reduced sphingosine 1-phosphate production, suggesting that PLC/PKC beta 2 are upstream regulators of SK1 in the pathway. Taken together, these data provide evidence that activation of PLC and PKC beta 2 by the IGF-II/M6P receptor are required for the activation of SK1. (Molecular Endocrinology 25:2144-2156, 2011)

AB Lipid nanoparticles (LNPs) are currently the most effective in vivo delivery systems for silencing target genes in hepatocytes employing small interfering RNA. Antigen-presenting cells (APCs) are also potential targets for LNP siRNA. We examined the uptake, intracellular trafficking, and gene silencing potency in primary bone marrow macrophages (bmMF) and dendritic cells of siRNA formulated in LNPs containing four different ionizable cationic lipids namely DLinDAP, DLinDMA, DLinK-DMA, and DLinKC2-DMA. LNPs containing DLinKC2-DMA were the most potent formulations as determined by their ability to inhibit the production of GAPDH target protein. Also, LNPs containing DLinKC2-DMA were the most potent intracellular delivery agents as indicated by confocal studies of endosomal versus cytoplamic siRNA location using fluorescently labeled siRNA. DLinK-DMA and DLinKC2-DMA formulations exhibited improved gene silencing potencies relative to DLinDMA but were less toxic. In vivo results showed that LNP siRNA systems containing DLinKC2-DMA are effective agents for silencing GAPDH in APCs in the spleen and peritoneal cavity following systemic administration. Gene silencing in APCs was RNAi mediated and the use of larger LNPs resulted in substantially reduced hepatocyte silencing, while similar efficacy was maintained in APCs. These results are discussed with regard to the potential of LNP siRNA formulations to treat immunologically mediated diseases.

AB Somatic copy-number alterations (SCNA) are a hallmark of many cancer types, but the mechanistic basis underlying their genome-wide patterns remains incompletely understood. Here we integrate data on DNA replication timing, long-range interactions between genomic material, and 331,724 SCNAs from 2,792 cancer samples classified into 26 cancer types. We report that genomic regions of similar replication timing are clustered spatially in the nucleus, that the two boundaries of SCNAs tend to be found in such regions, and that regions replicated early and late display distinct patterns of frequencies of SCNA boundaries, SCNA size and a preference for deletions over insertions. We show that long-range interaction and replication timing data alone can identify a significant proportion of SCNAs in an independent test data set. We propose a model for the generation of SCNAs in cancer, suggesting that data on spatial proximity of regions replicating at the same time can be used to predict the mutational landscapes of cancer genomes.

AB The accumulation of data on structural variation in cancer genomes provides an opportunity to better understand the mechanisms of genomic alterations and the forces of selection that act upon these alterations in cancer. Here we test evidence supporting the influence of two major forces, spatial chromosome structure and purifying (or negative) selection, on the landscape of somatic copy-number alterations (SCNAs) in cancer(1). Using a maximum likelihood approach, we compare SCNA maps and three-dimensional genome architecture as determined by genome-wide chromosome conformation capture (HiC) and described by the proposed fractal-globule model(2,3). This analysis suggests that the distribution of chromosomal alterations in cancer is spatially related to three-dimensional genomic architecture and that purifying selection, as well as positive selection, influences SCNAs during somatic evolution of cancer cells.

AB We compared bona fide human induced pluripotent stem cells (iPSCs) derived from umbilical cord blood (CB) cells and neonatal keratinocytes (K). As a consequence of both incomplete erasure of tissue-specific methylation and aberrant de novo methylation, CB-iPSCs and K-iPSCs were distinct in genome-wide DNA methylation profiles and differentiation potential. Extended passage of some iPSC clones in culture did not improve their epigenetic resemblance to embryonic stem cells, implying that some human iPSCs retain a residual 'epigenetic memory' of their tissue of origin.

AB The International Stem Cell Initiative analyzed 125 human embryonic stem (ES) cell lines and 11 induced pluripotent stem (iPS) cell lines, from 38 laboratories worldwide, for genetic changes occurring during culture. Most lines were analyzed at an early and late passage. Single-nucleotide polymorphism (SNP) analysis revealed that they included representatives of most major ethnic groups. Most lines remained karyotypically normal, but there was a progressive tendency to acquire changes on prolonged culture, commonly affecting chromosomes 1, 12, 17 and 20. DNA methylation patterns changed haphazardly with no link to time in culture. Structural variants, determined from the SNP arrays, also appeared sporadically. No common variants related to culture were observed on chromosomes 1, 12 and 17, but a minimal amplicon in chromosome 20q11.21, including three genes expressed in human ES cells, ID1, BCL2L1 and HM13, occurred in >20% of the lines. Of these genes, BCL2L1 is a strong candidate for driving culture adaptation of ES cells.

AB Recent advances in technologies for genome- and proteome-scale measurements and perturbations promise to accelerate discovery in every aspect of biology and medicine. Although such rapid technological progress provides a tremendous opportunity, it also demands that we learn how to use these tools effectively. One application with great potential to enhance our understanding of biological systems is the unbiased reconstruction of genetic and molecular networks. Cells of the immune system provide a particularly useful model for developing and applying such approaches. Here, we review approaches for the reconstruction of signalling and transcriptional networks, with a focus on applications in the mammalian innate immune system.

AB Sorafenib is an inhibitor of multiple kinases that has demonstrated antiproliferative and antiangiogenic activity in a number of in vitro and in vivo model systems. A phase I study was conducted to determine the maximum tolerated dose (MTD) of sorafenib in patients with recurrent malignant glioma. Sorafenib was given orally, twice a day (BID), continuously in 28-day cycles. The dose was escalated in 2 groups of patients stratified by use of enzyme-inducing antiseizure drugs (+/- EIASDs). Dose-limiting toxicity (DLT) was defined as any grades 3-4 nonhematological toxicity, grade 4 hematological toxicity, and febrile neutropenia. The number of evaluable patients enrolled in the + EIASD and -EIASD arms were 23 and 24, respectively. DLTs were predominantly dermatological and gastrointestinal effects, as observed in previous clinical trials of sorafenib. The MTD was 600 mg BID for patients receiving EIASDs and 800 mg BID for those who were not. The plasma pharmacokinetics of sorafenib were not significantly affected by the concurrent administration of EIASDs. The MTD of sorafenib given orally BID on a continuous basis was established as 600 mg BID in patients with malignant glioma who were concurrently receiving EIASDs and 800 mg BID in those who were not. Further evaluation is warranted of sorafenib at the recommended MTD against recurrent or progressive malignant glioma in combination with other molecularly targeted drugs or in the newly diagnosed setting concurrent with chemoradiation.

TI Prevalence of Abnormalities Influences Cytologists' Error Rates in
Screening for Cervical Cancer
SO ARCHIVES OF PATHOLOGY & LABORATORY MEDICINE
LA English
DT Article
ID PROGRAM; NUMBERS; SMEARS; BREAST
AB Context.-Medical screening tasks are often difficult, visual searches with low target prevalence (low rates of disease). Under laboratory conditions, when targets are rare, nonexpert searchers show decreases in false-positive results and increases in false-negative results compared with results when targets are common. This prevalence effect is not due to vigilance failures or target unfamiliarity.
Objective.-To determine whether prevalence effects could be a source of elevated false-negative errors in medical experts.
Design.-We studied 2 groups of cytologists involved in cervical cancer screening (Boston, Massachusetts, and South Wales, UK). Cytologists evaluated photomicrographs of cells at low (2% or 5%) or higher (50%) rates of abnormality prevalence. Two versions of the experiment were performed. The Boston, Massachusetts, group made decisions of normal or abnormal findings using a 4-point rating scale. Additionally, the group from South Wales localized apparent abnormalities.
Results.-In both groups, there is evidence for prevalence effects. False-negative errors were 17% (higher prevalence), rising to 30% (low prevalence) in the Boston, Massachusetts, group. The error rate was 27% (higher prevalence), rising to 42% (low prevalence) in the South Wales group. (Comparisons between the 2 groups are not meaningful because the stimulus sets were different.)
Conclusions.-These results provide the first evidence, to our knowledge, that experts are not immune to the effects of prevalence even with stimuli from their domain of expertise. Prevalence is a factor to consider in screening for disease by human observers and has significant implications for cytology-based cervical cancer screening in the post-human papillomavirus vaccine era, when prevalence rates of high-grade lesions in the population are expected to decline.

AB Background and objectives Approximately 70% of illicit cocaine consumed in the United States is contaminated with levamisole. Most commonly used as a veterinary antihelminthic agent, levamisole is a known immunomodulating agent. Prolonged use in humans has been associated with cutaneous vasculitis and agranulocytosis. We describe the development of a systemic autoimmune disease associated with antineutrophil cytoplasmic antibodies (ANCA) in cocaine users. This complication appears to be linked to combined cocaine and levamisole exposure.
Design, setting, participants, & measurements Cases were identified between March 2009 and November 2010 at Massachusetts General Hospital's ANCA laboratory. Cocaine exposure was identified from patient history in all cases. Medical records were reviewed for clinical presentation and for laboratory and diagnostic evaluation.
Results Thirty cases of ANCA positivity associated with cocaine ingestion were identified. All had antimyeloperoxidase antibodies and 50% also had antiproteinase 3 antibodies. Complete clinical and laboratory data were available for 18 patients. Arthralgia (83%) and skin lesions (61%) were the most frequent complaints at presentation. Seventy-two percent of patients reported constitutional symptoms, including fever, night sweats, weight loss, or malaise. Four patients had biopsy-proven vasculitis. Two cases of acute kidney injury and three cases of pulmonary hemorrhage occurred. From the entire cohort of 30, two cases were identified during the first 3 months of our study period and nine cases presented during the last 3 months.
Conclusions We describe an association between the ingestion of levamisole-contaminated cocaine and ANCA-associated systemic autoimmune disease. Our data suggest that this is a potentially life-threatening complication of cocaine use. Clin J Am Soc Nephrol 6: 2799-2805, 2011. doi: 10.2215/CJN.03440411

AB Matrix metalloproteinases (MMPs) and monocyte chemoattractants are key modulators of the biological mechanisms triggered in the periodontium by mechanical forces. The gingival crevicular fluid (GCF) provides a non-invasive method to assess longitudinally the release of inflammatory mediators during orthodontic tooth movement. The goal of this study was to examine the GCF levels of MMP3, MMP-9, and MMP-13 and of the chemokines macrophage inflammatory protein (MIP)-1 beta, monocyte chemoattractant protein (MCP)-1, and regulated on activation normal T cells expressed and secreted (RANTES) at different time points during orthodontic tooth movement. Fourteen subjects (three males and 11 females, 18.8 +/- 4.8 years of age; range from 12 to 28 years) had their maxillary canines retracted. Thirty-second GCF samples were collected from the tension and pressure sides 7 days prior to the activation of the orthodontic appliance, on the day of activation, and after 1 and 24 hours, and 14, 21, and 80 days of constant force application. The volume of GCF was measured and samples analysed using a multiplexed bead immunoassay for the content of the six target molecules. Differences in the mean GFC volumes and mean level for each analyte over time were assessed using the Friedman test, and differences between the tension and pressure sides at each time point with the Mann-Whitney test.
The mean levels of the three MMPs changed significantly over time but only at the compression side (P < 0.05, Friedman test). The GCF levels of the three chemokines were not affected by the application of mechanical stress. The levels of MMPs in GCF at the pressure side are modulated by the application of orthodontic force.

AB Liver disease continues to represent a critical mediator of morbidity and mortality in those with human immunodeficiency virus (HIV) infection. The frequent presence and overlap of concomitant injurious processes, including hepatitis C virus and hepatitis B virus infections, hepatoxicity associated with antiretroviral therapeutic agents, alcohol, and other toxins, in the setting of immunosuppression lead to rapid fibrotic progression and early development of end-stage liver disease. This conference summary describes the proceedings of a state-of-the-art gathering of international experts designed to highlight the status of current research in epidemiology, natural history, pathogenesis, and treatment of HIV and liver disease.

AB Purpose: To use manganese-enhanced magnetic resonance imaging (MEMRI) at 25 x 25 x 800 mu m(3) to image different retinal and vascular layers in the rat retinas.
Materials and Methods: Manganese-chloride was injected intraocularly in normal (n = 5) and Royal College of Surgeons (RCS, an model of photoreceptor degeneration) (n = 5) rats at postnatal day 90. MEMRI at 4.7 T was performed 24 hours later. MRI was repeated following intravenous Gd-DTPA in the same animals to highlight the vasculatures. Layer assignment and thickness were compared to histology.
Results: MEMRI 24 hours after intravitreal manganese-chloride injection revealed seven bands of alternating hyper- and hypointensities, corresponding histologically to the ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer, outer nuclear layer, photoreceptor-segment layer, and choroidal vascular layer. Intravenous Gd-DTPA-which does not cross the blood-retinal barrier and the retinal pigment epithelium-further enhanced the two layers bounding the retina, corresponding to the retinal and choroidal vascular layers, but not the avascular outer nuclear layer and the photoreceptor-segment layer. MEMRI of the RCS retinas revealed the loss of the outer plexiform layer, outer nuclear layer, and photoreceptor-segment layer. Histological analysis corroborated the MRI laminar assignments and thicknesses.
Conclusion: Lamina-specific retinal structures neurodegenerative changes to structure in retinal diseases can be detected using MEMRI.

AB Recurrence after resection of primary gastrointestinal stromal tumor (GIST) is an unfortunately all-too-common phenomenon. The principal treatment for recurrent GIST is the first-line tyrosine kinase inhibitor (TKI) imatinib mesylate. Those who progress on, or are intolerant of imatinib, are treated with second-line TKI sunitinib malate. Cytoreductive surgery may be considered as an "adjuvant" therapy for patients with disease stabilized on imatinib, and, on an individual basis, sunitinib. J. Surg. Oncol. 2011;104:915-920.

ID CANCER
AB Humoral hypercalcemia of malignancy (HHM) is the cause of hypercalcemia in the majority of patients with hypercalcemia and cancer. Parathyroid hormone-related protein (PTH-RP) has been identified as the circulating factor that mediates HHM. An N-terminal and a C-terminal PTH-RP are clinically useful assays for screening patients for HHM, and both assays are elevated in such patients. C-terminal PTH-RP depends on glomerular filtration and accumulates in patients with renal failure without malignancy, resulting in falsely-elevated levels, whereas N-terminal PTH-RP is low or undetectable in such patients. We present a case of a patient with renal failure and hypercalcemia who did not have an obvious malignancy and who presented with an elevated C-terminal PTH-RP level and a normal N-terminal PTH-RP. In patients with renal failure and hypercalcemia without cancer, C-terminal PTH-RP may be falsely elevated, especially if the eGFR is <20 mL/minute, and in such patients, N-terminal PTH-RP, because it is less affected by renal function, is the preferred test.

AB Introduction: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease. We sought to determine whether peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1 alpha) would have a beneficial effect on this disease. Methods: PGC-1 alpha transgenic mice were crossed with SOD1 mutant G93A DL mice. Results: We observed a moderate but non-significant increase in average lifespan in PGC-1 alpha/G93A DL mice, as compared with G93A DL mice (292 +/- 3 days vs. 274 +/- 7 days). Although the onset of ALS was not altered, progression of the disease was significantly slower (similar to 34% increase in duration) in the PGC-1 alpha/G93A DL mice. These mice also exhibited markedly improved performance on the rotarod test, and the improved motor activity was associated with a decreased loss of motor neurons and less degeneration of neuromuscular junctions. Conclusion: A sustained level of excitatory amino acid transporter protein 2 (EAAT2) in astrocytes of the PGC-1 alpha/G93A DL mice may contribute to neuronal protection.

AB Estrogen receptor (ER)-negative breast cancer shows a higher incidence in women of African ancestry compared to women of European ancestry. In search of common risk alleles for ER-negative breast cancer, we combined genome-wide association study (GWAS) data from women of African ancestry (1,004 ER-negative cases and 2,745 controls) and European ancestry (1,718 ER-negative cases and 3,670 controls), with replication testing conducted in an additional 2,292 ER-negative cases and 16,901 controls of European ancestry. We identified a common risk variant for ER-negative breast cancer at the TERT-CLPTM1L locus on chromosome 5p15 (rs10069690: per-allele odds ratio (OR) = 1.18 per allele, P = 1.0 x 10(-10)). The variant was also significantly associated with triple-negative (ER-negative, progesterone receptor (PR)-negative and human epidermal growth factor-2 (HER2)-negative) breast cancer (OR = 1.25, P = 1.1 x 10(-9)), particularly in younger women (<50 years of age) (OR = 1.48, P = 1.9 x 10(-9)). Our results identify a genetic locus associated with estrogen receptor negative breast cancer subtypes in multiple populations.

AB Two common variants in the gene encoding complement factor H (CFH), the Y402H substitution (rs1061170, c.1204C>T)(1-4) and the intronic rs1410996 SNP(5,6), explain 17% of age-related macular degeneration (AMD) liability. However, proof for the involvement of CFH, as opposed to a neighboring transcript, and knowledge of the potential mechanism of susceptibility alleles are lacking. Assuming that rare functional variants might provide mechanistic insights, we used genotype data and high-throughput sequencing to discover a rare, high-risk CFH haplotype with a c.3628C>T mutation that resulted in an R1210C substitution. This allele has been implicated previously in atypical hemolytic uremic syndrome, and it abrogates C-terminal ligand binding(7,8). Genotyping R1210C in 2,423 AMD cases and 1,122 controls demonstrated high penetrance (present in 40 cases versus 1 control, P = 7.0 x 10(-6)) and an association with a 6-year-earlier onset of disease (P = 2.3 x 10(-6)). This result suggests that loss-of-function alleles at CFH are likely to drive AMD risk. This finding represents one of the first instances in which a common complex disease variant has led to the discovery of a rare penetrant mutation.

AB Background: Immediate single-stage direct-to-implant breast reconstruction with acellular dermal matrix optimizes aesthetics by preserving the mastectomy skin envelope. The authors report trends, early complications, and costs.
Methods: A retrospective review of three surgeons' experience was performed for immediate single-stage implant reconstruction with acellular dermal matrix and tissue expander reconstruction without it at Massachusetts General Hospital.
Results: Two hundred eleven patients had 331 direct-to-implant reconstructions using AlloDerm following nipple-sparing (n = 66) or skin-sparing (n = 265) mastectomy for cancer (n = 216) or prophylaxis (n = 115). The number of single-stage implant reconstructions increased from seven in 2006 to 116 in 2009. The percentage performed for prophylaxis increased from 29 percent to 41 percent. Fifty-one patients underwent preoperative (n = 33) or postoperative (n = 18) irradiation. Total complications included 10 infections (3.0 percent), five seromas (1.5 percent), four hematomas (1.2 percent), and 30 reconstructions (9.1 percent), with skin necrosis leading to five implant losses (1.5 percent). Tissue expander reconstruction without AlloDerm had a similar total complication rate (158 reconstructions) (p = 0.18), including nine infections (5.7 percent), three seromas (1.9 percent), three hematomas (1.9 percent), and 16 reconstructions (10.1 percent), with skin necrosis leading to 11 implant losses (7.0 percent). A higher complication rate occurred in the surgeons' combined first year performing single-stage implant reconstruction (21.4 percent) compared with subsequent years (10.9 percent) (p < 0.02) and in one-or two-stage reconstruction patients undergoing irradiation (p = 0.005). There was no significant difference in total overall costs (p = 0.8).
Conclusions: Immediate single-stage implant reconstruction using acellular dermal matrix offers a cost-effective reconstruction with a low complication rate. This may be the procedure of choice in select patients. (Plast. Reconstr. Surg. 128: 1170, 2011.)

AB Aspergillosis remains a significant cause of morbidity and mortality. The spectrum of disease is diverse and ranges from noninvasive disease with an excessive immune response, such as in allergic bronchopulmonary aspergillosis (ABPA), to a lack of an immune response as seen in patients with quantitative or qualitative granulocyte deficits and subsequent invasive pulmonary aspergillosis.
Noninvasive diagnostic testing has improved the time to initiation of effective antifungal therapy, and numerous agents in different therapeutic classes are now available as treatment options. Voriconazole remains the preferred agent in the treatment of invasive pulmonary aspergillosis, and recent data have increased interest in the potential of combination therapy against this often lethal infection. The role of host genetics in selecting patients that may benefit from more aggressive antifungal prophylaxis or treatment practices remains unclear but is likely to guide therapeutic choices as newer data become available.

AB Cryptococcosis is an invasive fungal infection (IFI), caused predominantly by Cryptococcus neoformans or Cryptococcus gattii, that affects both immunocompromised (IC) and non-IC patients. Although the most serious disease manifestation is meningoencephalitis, cryptococcal pneumonia is underdiagnosed and may disseminate to the central nervous system (CNS) and other sites depending upon host defenses and administration of appropriate antifungal therapy. The clinical presentation of pulmonary cryptococcosis varies along a spectrum from asymptomatic infection to severe pneumonia and respiratory failure, and the radiological presentation can be characterized by an array of findings, including nodules, consolidation, cavitary lesions, and a diffuse interstitial pattern. Diagnosis most often relies upon isolation of Cryptococcus from a pulmonary specimen in the appropriate clinical and radiological context. Treatment recommendations include induction therapy with an amphotericin B preparation and flucytosine for IC patients and those with severe disease and fluconazole for mild-to-moderate, localized disease. Knowledge of the pathophysiology, epidemiology, clinical presentation, and treatment of pulmonary cryptococcosis may lead to greater recognition of this underdiagnosed IFI and improved outcomes.

ID CORONARY-HEART-DISEASE; CARDIOVASCULAR HEALTH; ATHEROSCLEROSIS
AB Background and Purpose-Few studies have assessed post-glucose load measures of insulin resistance and ischemic stroke risk, and data are sparse for older adults. We investigated whether fasting and post-glucose load measures of insulin resistance were related to incident ischemic stroke in nondiabetic, older adults.
Methods-Participants were men and women in the Cardiovascular Health Study, age 65+ years and without prevalent diabetes or stroke at baseline, followed for 17 years for incident ischemic stroke. The Gutt insulin sensitivity index was calculated from baseline body weight and from fasting and 2-hour postload insulin and glucose; a lower Gutt index indicates higher insulin resistance.
Results-Analyses included 3442 participants (42% men) with a mean age of 73 years. Incidence of ischemic stroke was 9.8 strokes per 1000 person-years. The relative risk (RR) for lowest quartile versus highest quartile of Gutt index was 1.64 (95% CI, 1.24-2.16), adjusted for demographics and prevalent cardiovascular and kidney disease. Similarly, the adjusted RR for highest quartile versus lowest quartile of 2-hour glucose was 1.84 (95% CI, 1.39-2.42). In contrast, the adjusted RR for highest quartile versus lowest quartile of fasting insulin was 1.10 (95% CI, 0.84-1.46).
Conclusions-In nondiabetic, older adults, insulin resistance measured by Gutt index or 2-hour glucose, but not by fasting insulin, was associated with risk of incident ischemic stroke. (Stroke. 2011;42:3347-3351.)

AB Background and Purpose-Black/white disparities in stroke incidence are well documented, but few studies have assessed the contributions to the disparity. Here we assess the contribution of "traditional" risk factors.
Methods-A total of 25 714 black and white men and women, aged >= 45 years and stroke-free at baseline, were followed for an average of 4.4 years to detect stroke. Mediation analysis using proportional hazards analysis assessed the contribution of traditional risk factors to racial disparities.
Results-At age 45 years, incident stroke risk was 2.90 (95% CI: 1.72-4.89) times more likely in blacks than in whites and 1.66 (95% CI: 1.34-2.07) times at age 65 years. Adjustment for risk factors attenuated these excesses by 40% and 45%, respectively, resulting in relative risks of 2.14 (95% CI: 1.25-3.67) and 1.35 (95% CI: 1.08-1.71). Approximately one half of this mediation is attributable to systolic blood pressure. Further adjustment for socioeconomic factors resulted in total mediation of 47% and 53% to relative risks of 2.01 (95% CI: 1.16-3.47) and 1.30 (1.03-1.65), respectively.
Conclusions-Between ages 45 to 65 years, approximately half of the racial disparity in stroke risk is attributable to traditional risk factors (primarily systolic blood pressure) and socioeconomic factors, suggesting a critical need to understand the disparity in the development of these traditional risk factors. Because half of the excess stroke risk in blacks is not attributable to traditional risk factors and socioeconomic factors, differential impact of risk factors, residual confounding, or nontraditional risk factors may also play a role.

AB Background and Purpose-High experimental variability in mouse embolic stroke models could mask the effects of experimental treatments. We hypothesized that imaging thrombus directly would allow this variability to be controlled.
Methods-We optically labeled thrombi with a near-infrared fluorescent (NIRF) probe C15 that is covalently linked to fibrin by factor-XIIIa. Labeled thrombus was injected into the left distal internal carotid artery (ICA) of C57/BL6 mice (n=47), near its bifurcation, and laser-Doppler cerebral-blood-flow (CBF) was assessed for 30 minutes. NIRF thrombus imaging was done ex vivo at 24 hours.
Results-CBF variably decreased to 43.9 +/- 17.3% at 5 minutes (rCBF; 11.2 similar to 80.4%). NIRF thrombus imaging at 24 hours showed variability in distribution (ICA bifurcation, adjacent and/or remote areas) and burden (2279 +/- 1270 pixels; 0 similar to 5940 pixels). Final infarct size was also variable (21.0 +/- 10.3%; 4.7 similar to 60.3% of the bihemispheric volume). Despite this heterogeneity, a strong thrombus-infarct correlation was maintained. The left hemispheric target infarct size (% of the hemisphere) correlated with thrombus burden, as a stronger predictor of infarct volume (P<0.001, r=0.50) than rCBF (P=0.02, r=-0.34). The infarct size was best predicted by a combination of thrombus imaging and CBF: left-hemispheric big-thrombi (>1865 pixels)/low-rCBF (<= 42%) had an infarct volume of 56.9 +/- 10.4% (n=12), big-thrombi/high-rCBF had 45.9 +/- 23.5% (n=11), small-thrombi/low-rCBF 35.7 +/- 17.3% (n=11) and small-thrombi/ high-rCBF 27.3 +/- 16.4% (n=12).
Conclusions-This is the first study to demonstrate that the highly heterogeneous nature of the mouse embolic stroke model can be characterized and managed by using near-infrared fluorescent thrombus imaging combined with CBF monitoring to stratify animals into useful subgroups.

TI Plasma-Type Gelsolin Is Decreased in Human Blood and Cerebrospinal Fluid
After Subarachnoid Hemorrhage
SO STROKE
LA English
DT Article
DE biomarker; gelsolin; matrix metalloproteinases; subarachnoid hemorrhage
ID BRAIN-INJURY; ACTIN
AB Background and Purpose-Subarachnoid hemorrhage (SAH) pathophysiology involves neurovascular proteolysis and inflammation. How these 2 phenomena are related remains unclear. We hypothesize that matrix metalloproteinases (MMPs) mediate the depletion of anti-inflammatory plasma-type gelsolin (pGSN).
Methods-We enrolled 42 consecutive SAH subjects and sampled cerebrospinal fluid (CSF) and blood on post-SAH Days 2 to 3, 4 to 5, 6 to 7, and 10 to 14. Control subjects were 20 consecutive non-SAH hydrocephalus patients with lumbar drains. Enzyme-linked immunosorbent assay, Western blotting, and zymography were used to quantify pGSN and MMP-9.
Results-In CSF, pGSN was lower in SAH compared with control subjects on post-SAH Days 2 to 3 (P = 0.0007), 4 to 5 (P = 0.041), and 10 to 14 (P = 0.007). In blood, pGSN decreased over time (P = 0.001) and was lower in SAH compared with control subjects on post-SAH Days 4 to 5 (P = 0.037), 6 to 7 (P = 0.006), and 10 to 14 (P = 0.006). Western blots demonstrated that SAH CSF had novel bands at 52 and 46 kDa, representing cleaved pGSN fragments. Gelatin zymography showed that CSF MMP-9 was elevated in SAH compared with control subjects. Higher CSF MMP-9 correlated with lower CSF pGSN on post-SAH Day 7 (r = -0.38; P = 0.05).
Conclusions-SAH is associated with decreased CSF and blood pGSN and elevated CSF MMP-9. Novel cleaved pGSN fragments are present in CSF of SAH subjects, consistent with pGSN cleavage by MMPs. Because pGSN is known to inhibit inflammatory mediators, these findings suggest that MMPs may reduce pGSN and exacerbate inflammation after SAH. Further studies are warranted to investigate the mechanisms underlying MMP-pGSN signaling in SAH. (Stroke. 2011; 42: 3624-3627.)

TI A Comparison of Acute Hemorrhagic Stroke Outcomes in 2 Populations The
Crete-Boston Study

LA English
DT Article
DE dexamethasone; ICH; stroke management
ID SUPRATENTORIAL INTRACEREBRAL HEMORRHAGE; DEXAMETHASONE
AB Background and Purpose-Although corticosteroid use in acute hemorrhagic stroke is not widely adopted, management with intravenous dexamethasone has been standard of care at the University Hospital of Heraklion, Crete with observed outcomes superior to those reported in the literature. To explore this further, we conducted a retrospective, multivariable-adjusted 2-center study.
Methods-We studied 391 acute hemorrhagic stroke cases admitted to the University Hospital of Heraklion, Crete between January 1997 and July 2010 and compared them with 510 acute hemorrhagic stroke cases admitted to Massachusetts General Hospital, Boston, from January 2003 to September 2009. Of the Cretan cases, 340 received a tapering scheme of intravenous dexamethasone, starting with 16 to 32 mg/day, whereas the Boston patients were managed without steroids.
Results-The 2 cohorts had comparable demographics and stroke severity on admission, although anticoagulation was more frequent in Boston. The in-hospital mortality was significantly lower on Crete (23.8%, n = 340) than in Boston (38.0%, n = 510; P < 0.001) as was the 30-day mortality (Crete: 25.4%, n = 307; Boston: 39.4%, n = 510; P < 0.001). Exclusion of patients on anticoagulants showed even greater differences (30-day mortality: Crete 20.8%; n = 259; Boston 37.0%; n = 359; P < 0.001). The improved survival on Crete was observed 3 days after initiation of intravenous dexamethasone and was pronounced for deep-seated hemorrhages. After adjusting for acute hemorrhagic stroke volume/location, Glasgow Coma Scale, hypertension, diabetes mellitus, smoking, coronary artery disease and statin, antiplatelet, and anticoagulant use, intravenous dexamethasone treatment was associated with better functional outcomes and significantly lower risk of death at 30 days (OR, 0.357; 95% CI, 0.174-0.732).
Conclusions-This study suggests that intravenous dexamethasone improves outcome in acute hemorrhagic stroke and supports a randomized clinical trial using this approach. (Stroke. 2011; 42: 3640-3642.)

AB Characterizing the dynamic mechanical properties of brain tissue is deemed important for developing a comprehensive knowledge of the mechanisms underlying brain injury. The results gathered to date on the tissue properties have been mostly obtained in vitro. Learning how these results might differ quantitatively from those encountered in vivo is a critical step towards the development of biofidelic brain models. The present study provides novel and unique experimental results on, and insights into, brain biorheology in vivo, in situ and in vitro, at large deformations, in the quasi-static and dynamic regimes. The nonlinear dynamic response of the cerebral cortex was measured in indentation on the exposed frontal and parietal lobes of anesthetized porcine subjects. Load-unload cycles were applied to the tissue surface at sinusoidal frequencies of 10, 1, 0.1 and 0.01 Hz. Ramp-relaxation tests were also conducted to assess the tissue viscoelastic behavior at longer times. After euthanasia, the indentation test sequences were repeated in situ on the exposed cortex maintained in its native configuration within the cranium. Mixed gray and white matter samples were subsequently excised from the superior cortex to be subjected to identical indentation test segments in vitro within 6-7 h post mortem. The main response features (e.g. nonlinearities, rate dependencies, hysteresis and conditioning) were measured and contrasted in vivo, in situ and in vitro. The indentation response was found to be significantly stiffer in situ than in vivo. The consistent, quantitative set of mechanical measurements thereby collected provides a preliminary experimental database, which may be used to support the development of constitutive models for the study of mechanically mediated pathways leading to traumatic brain injury.

TI Clinical utility of electrodermal activity at acupuncture points: a
narrative review
SO ACUPUNCTURE IN MEDICINE
LA English
DT Review
ID DOUBLE-BLIND; SKIN
AB Objectives To provide an in-depth analysis of seven well-reported studies that examined electrodermal activity (EDA) at acupuncture points with regard to three commonly held tenets of acupuncture: (1) EDA at pathology-related acupuncture points is distinguishable from non-pathology-related acupuncture points; (2) EDA at acupuncture points can assist in diagnosing and monitoring therapeutic progress; and (3) EDA at acupuncture points is able to identify substances that are either therapeutically beneficial or toxic to an individual.
Methods Seven of 29 studies that scored >50% on their quality of reporting 54 essential technical and clinical details of EDA testing in human patients were identified from a previous literature review. Fourteen categories of data were extracted from these seven studies for further discussion.
Results Two studies compared EDA at pathology-related auricular acupuncture points to non-pathology-related sites. Two studies correlated EDA measurements at sites other than auricular acupuncture points with the presence of specific medical conditions. The final three studies assessed changes in EDA at acupuncture points on the fingers and toes when different substances were placed in the electrical circuit with the patient.
Conclusions This review highlights the heterogeneity of approaches to EDA assessments and the discrepancies between common clinical practice and the scientific evidence to support that practice. It also provides pilot data that suggest EDA testing at auricular acupuncture points may distinguish pathology-related acupuncture points from non-pathology-related points; decreased skin conductance correlates with tiredness or low energy; and EDA testing at the Jing-Well acupuncture points, on the tips of the fingers and toes, may assist in monitoring effectiveness of acupuncture treatment. The evidence does not support the use of VEGA testing for allergic status.

AB Patients with chronic kidney disease (CKD) have a disproportionate burden of coronary artery disease and commonly undergo revascularization. The role and safety of percutaneous coronary intervention (PCI) using drug-eluting stents (DESs) verses bare-metal stents in patients with CKD not on renal replacement therapy has not been fully evaluated. This study investigated the efficacy and safety of DES in patients with CKD not on renal replacement therapy. Patients were drawn from the National Heart, Lung, and Blood Institute Dynamic Registry and were stratified by renal function based on estimated glomerular filtration rate (GFR). Of the 4,157 participants, 1,108 had CKD ("low GFR" <60 ml/min/1.73 m(2)), whereas 3,049 patients had normal renal function ("normal GFR" >= 60 ml/min/1.73 m(2)). For each stratum of renal function we compared risk of death, myocardial infarction, or repeat revascularization between subjects who received DESs and bare-metal stents at the index procedure. Patients with low GFR had higher 1-year rates of death and myocardial infarction and a decreased rate of repeat revascularization compared to patients with normal GFR. Use of DESs was associated with a decreased need for repeat revascularization in the normal-GFR group (adjusted hazard ratio 0.63, 95% confidence interval 0.50 to 0.79, p <0.001) but not in the low-GFR group (hazard ratio 0.69, 95% confidence interval 0.45 to 1.06, p = 0.09). Risks of death and myocardial infarction were not different between the 2 stents in either patient population. In conclusion, presence of CKD predicted poor outcomes after PCI with high rates of mortality regardless of stent type.

AB Autophagy is a highly conserved homeostatic pathway by which cells transport damaged proteins and organelles to lysosomes for degradation. Dysregulation of autophagy contributes to the pathogenesis of clinically important disorders in a variety of organ systems but, until recently, little was known about its relationship to diseases of the lung. However, there is now growing evidence at the basic research level that autophagy is linked to the pathogenesis of important pulmonary disorders such as chronic obstructive pulmonary disease, cystic fibrosis, and tuberculosis. In this review, we provide an introduction to the field of autophagy research geared to clinical and research pulmonologists. We focus on the best-studied autophagic mechanism, macroautophagy, and summarize studies that link the regulation of this pathway to pulmonary disease. Last, we offer our perspective on how a better understanding of macroautophagy might be used for designing novel therapies for pulmonary disorders.

TI Biomechanical Evaluation of Knee Joint Laxities and Graft Forces After
Anterior Cruciate Ligament Reconstruction by Anteromedial Portal,
Outside-In, and Transtibial Techniques
SO AMERICAN JOURNAL OF SPORTS MEDICINE

DT Article
DE anterior cruciate ligament reconstruction; anteromedial portal;
outside-in; transtibial; knee kinematics
ID FEMORAL TUNNEL PLACEMENT; 2-INCISION TECHNIQUE; ACL RECONSTRUCTION;
TIBIAL TUNNEL; TENDON
AB Background: Recently, anatomic anterior cruciate ligament (ACL) reconstruction is emphasized to improve joint laxity and to potentially avert initiation of cartilage degeneration. There is a paucity of information on the efficacy of ACL reconstructions by currently practiced tunnel creation techniques in restoring normal joint laxity.
Study Design: Controlled laboratory study.
Hypothesis: Anterior cruciate ligament reconstruction by the anteromedial (AM) portal technique, outside-in (OI) technique, and modified transtibial (TT) technique can equally restore the normal knee joint laxity and ACL forces.
Methods: Eight fresh-frozen human cadaveric knee specimens were tested using a robotic testing system under an anterior tibial load (134 N) at 0 degrees, 30 degrees, 60 degrees, and 90 degrees of flexion and combined torques (10-N.m valgus and 5-N.m internal tibial torques) at 0 degrees and 30 degrees of flexion. Knee joint kinematics, ACL, and ACL graft forces were measured in each knee specimen under 5 different conditions (ACL-intact knee, ACL-deficient knee, ACL-reconstructed knee by AM portal technique, ACL-reconstructed knee by OI technique, and ACL-reconstructed knee by TT technique).
Results: Under anterior tibial load, no significant difference was observed between the 3 reconstructions in terms of restoring anterior tibial translation (P > .05). However, none of the 3 ACL reconstruction techniques could completely restore the normal anterior tibial translations (P < .05). Under combined tibial torques, both AM portal and OI techniques closely restored the normal knee anterior tibial translation (P > .05) at 0 degrees of flexion but could not do so at 30 degrees of flexion (P < .05). The ACL reconstruction by the TT technique was unable to restore normal anterior tibial translations at both 0 degrees and 30 degrees of flexion under combined tibial torques (P < .05). Forces experienced by the ACL grafts in the 3 reconstruction techniques were lower than those experienced by normal ACL under both the loading conditions.
Conclusion: Anterior cruciate ligament reconstructions by AM portal, OI, and modified TT techniques are biomechanically comparable with each other in restoring normal knee joint laxity and in situ ACL forces.
Clinical Relevance: Anterior cruciate ligament reconstructions by AM portal, OI, and modified TT techniques result in similar knee joint laxities. Technical perils and pearls should be carefully considered before choosing a tunnel creating technique.

AB Background: All-inside meniscal repairs are performed with increasing frequency because of the availability of newly developed devices. A comparison of their biomechanical characteristics may aid physicians in selecting a method of meniscal repair.
Hypothesis: All-inside meniscal repairs will be superior to their inside-out controls in response to cyclic loading and load-to-failure testing.
Study Design: Controlled laboratory study.
Methods: Sixty-six bucket-handle tears in matched porcine menisci were repaired using the Ultra FasT-Fix, Meniscal Cinch, Ultrabraid No. 0, and FiberWire 2-0 sutures. Initial displacement, cyclic loading (100, 300, and 500 cycles), and load-to-failure testing were performed. The displacement, response to cyclic loading, and mode of failure were recorded. The stiffness was calculated.
Results: The Meniscal Cinch demonstrated a significantly higher initial displacement than the other methods tested (P = .04). No significant difference was found among the methods in response to cyclic loading. The inside-out FiberWire repair demonstrated the highest load to failure (120.8 +/- 23.5 N) and was significantly higher than both the Meniscal Cinch (64.8 +/- 24.1 N, P < .001) and the Ultra FasT-Fix (88.3 +/- 14.3 N, P = .002). It was not significantly higher than the inside-out Ultrabraid suture repair (98.8 +/- 29.2 N). The inside-out FiberWire repair had the highest stiffness (28.7 +/- 7.8 N/mm). It was significantly higher than the Meniscal Cinch (18.0 +/- 8.8 N/mm, P = .01). The most common mode of failure in all methods was suture failure.
Conclusion: An inside-out suture repair affords surgeons the best overall biomechanical characteristics of the devices tested (initial displacement, response to cyclic loading, and load to failure). For an all-inside repair, the Ultra FasT-Fix reproduces the characteristics of its matched inside-out suture repair more closely than the Meniscal Cinch.
Clinical Relevance: Inside-out sutures and all-inside devices have similar responses to cyclic loading.

AB We have previously reported that transplantation (Tx) of prevascularized donor islets as composite islet-kidneys (IK) reverses diabetic hyperglycemia in miniature swine. In order to test the potential clinical applicability of this strategy, we have extended it to a fully allogeneic nonhuman primate model. IKs were prepared in baboons by isolating islets from 50% to 70% partial pancreatectomies and injecting them under the autologous renal capsule, allowing vascularization before allogeneic Tx. Baboons with diabetes induced by stereptozotocin or total pancreatectomy, received composite IKs (n = 3) or free islets under the renal capsule or intraportally (n = 3), across fully allogeneic barriers with an immunosuppressive regimen consisting of ATG followed by MMF and tacrolimus. FBS of two of IK recipients decreased immediately after Tx and no insulin therapy was required throughout the experimental period (225 and 301 days). In contrast, all recipients of allogeneic free islets showed unstable FBS levels and required insulin within 2 months. We conclude that in addition to maintaining creatinine in the normal range, fully allogeneic IKs from single primate donors can achieve glucose regulation without insulin therapy, while free islets do not. These results support the feasibility of composite allogeneic IK Tx as a potential cure for end-stage diabetic nephropathy.

AB Fragmentation of multiple peptides in a single tandem mass scan impairs accuracy of isobaric mass tag based quantification. Consequently, practitioners aim at fragmenting peptide ions with the highest possible purity without compromising on sensitivity and coverage achieved in the experiment. Here we report the first systematic study optimizing delayed fragmentation options on Orbitrap instruments. We demonstrate that by delaying peptide fragmentation to occur closer to the apex of the chromatographic peak in liquid chromatography-tandem mass spectrometry (LC-MS/MS) experiments cofragmentation is reduced by 2-fold and peptides are fragmented with 2.8-fold better signal-to-noise ratios. This results in significantly improved accuracy of isobaric mass tag quantification. Further, we measured cofragmentation dependence on isolation width. In comparison to Orbitrap XL instruments the reduced space charging in the Orbitrap Velos enables isolation widths as narrow as 1 Th without impairing coverage, thus substantially reducing cofragmentation. When delayed peptide fragmentation and narrow isolation cofragmentation-induced ratio compression could be reduced by 32% on a log2 scale under width settings were both applied, otherwise identical conditions.

AB Objectives Interleukin-1 receptor-associated kinase (IRAK)-M suppresses Toll-like receptor (TLR)-mediated activation of innate immunity during infection. A similar role was hypothesised for IRAK-M in autoimmunity.
Methods Irak-m-deficient mice were crossed with autoimmune C57BL/6-lpr/lpr mice and detailed phenotype analysis was performed.
Results Irak-m deficiency converted the mild autoimmune phenotype of C57BL/6-lpr/lpr mice into a massive lymphoproliferative syndrome with lethal autoimmune lung disease and lupus nephritis. Irak-m deficiency induced a number of interferon-related genes, cytokines and plasma cell survival factors in spleen cells of these mice. Irak-m-deficient C57BL/6-lpr/lpr mice showed expansion of autoreactive T cells, dysfunctional regulatory T cells and plasma cells which was associated with increased lupus autoantibody production. TLR7 antagonism almost completely abrogated this phenotype consistent with IRAK-M-mediated suppression of TLR7 signalling in vitro.
Conclusions These data identify a previously unknown function of IRAK-M-namely, suppression of TLR7-mediated autoimmunity-and mutant IRAK-M as a previously unknown genetic risk for murine SLE.

AB Objective To identify biomarkers that distinguish between active antineutrophil cytoplasmic antibody (ANCA)associated vasculitis (AAV) and remission in a manner superior or complementary to established markers of systemic inflammation.
Methods. Markers of vascular injury and angiogenesis were measured before and after treatment in a large clinical trial in AAV: 163 subjects enrolled in the Rituximab in ANCA-Associated Vasculitis trial were screened for the present study. Serum levels of E-selectin, intercellular adhesion molecule 3 matrix metalloproteinase protein 1 (MMP-1), MMP-3, MMP-9, P-selectin, thrombomodulin, and vascular endothelial growth factor were measured at study screening (time of active disease) and at month 6. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels had been measured at the time of the clinical visit. The primary outcome measure was the difference in marker level between screening and month 6 among patients whose disease was in remission (Birmingham Vasculitis Activity Score for Wegener's granulomatosis [BVAS/WG] score of 0) at month 6.
Results. All patients had severe active vasculitis at screening (mean +/- SD BVAS/WG score 8.6 +/- 3.2). Among the 123 patients whose disease was clinically in remission at month 6, levels of all markers except E-selectin showed significant declines. MMP-3 levels were also higher among the 23 patients with active disease at month 6 than among the 123 patients whose disease was in remission. MMP-3 levels correlated weakly with ESR and CRP levels.
Conclusion. Many markers of vascular injury and angiogenesis are elevated in severe active AAV and decline with treatment, but MMP-3 appears to distinguish active AAV from remission better than the other markers studied. Further study of MMP-3 is warranted to determine its clinical utility in combination with conventional markers of inflammation and ANCA titers.

AB Objective The Veterans Affairs (VA) Rheumatoid Arthritis (VARA) registry and the VA Pharmacy Benefits Management database were linked to determine the association of methotrexate (MTX) adherence with rheumatoid arthritis (RA) disease activity.
Methods. For each patient, the medication possession ratio (MPR) was calculated for the first episode of MTX exposure of a duration of > 12 weeks for both new and established MTX users. High MTX adherence was defined as an MPR > 0.80 and low MTX adherence was defined as an MPR < 0.80. For each patient, the mean Disease Activity Score with 28 joints (DAS28) score, erythrocyte sedimentation rate (ESR), and C-reaction protein (CRP) level observed during registry followup were compared in high-versus low-adherence groups.
Results. In 455 RA patients, the prescribed doses of MTX (mean +/- SD 16 +/- 4 mg versus 16 +/- 4 mg; P = 0.6) were similar in high-adherence patients (n = 370) in comparison to low-adherence patients (n = 85). However, the actual observed MTX doses taken by patients were significantly higher in the high-adherence group (mean +/- SD 16 +/- 5 mg versus 11 +/- 3 mg; P < 0.001). DAS28 (mean +/- SD 3.6 +/- 1.2 versus 3.9 +/- 1.5; P < 0.02), ESR (mean +/- SD 24 +/- 18 versus 29 +/- 24 mm/hour; P = 0.05), and CRP level (mean +/- SD 1.2 +/- 1.3 versus 1.6 +/- 1.5 mg/dl; P < 0.03) were lower in the high-adherence group compared to those with low MTX adherence. These variances were not explained by differences in baseline demographic features, concurrent treatments, or whether MTX was initiated before or after VARA enrollment.
Conclusion. High MTX adherence was associated with improved clinical outcomes in RA patients treated with MTX. Adjustment for potential confounders did not alter the estimated effect of adherence. These results demonstrate the advantages of being able to merge clinical observations with pharmacy databases to evaluate antirheumatic drugs in clinical practice.

AB Objective Standard treatment for severe granulomatosis with polyangiitis (Wegener's) (GPA) is daily oral cyclophosphamide (CYC), a cytotoxic agent associated with ovarian failure. In this study, we assessed the rate of diminished ovarian reserve in women with GPA who received CYC versus methotrexate (MTX).
Methods. Patients in the Wegener's Granulomatosis Etanercept Trial received either daily CYC or weekly MTX and were randomized to etanercept or placebo. For all women ages <50 years, plasma samples taken at baseline or early in the study were evaluated against samples taken later in the study to compare levels of anti- Mullerian hormone (AMH) and follicle- stimulating hormone (FSH), endocrine markers of remaining egg supply. Diminished ovarian reserve was defined as an AMH level of < 1.0 ng/ml.
Results. Of 42 women in this analysis (mean age 35 years), 24 had CYC exposure prior to enrollment and 28 received the drug during the study. At study entry, women with prior CYC exposure had significantly lower AMH, higher FSH, and a higher rate of early menstruation cessation. For women with normal baseline ovarian function, 6 of 8 who received CYC during the trial developed diminished ovarian reserve, compared to 0 of 4 who did not receive CYC (P < 0.05). Changes in AMH correlated inversely with cumulative CYC dose (P < 0.01), with a 0.74 ng/ml decline in AMH level for each 10 gm of CYC.
Conclusion. Daily oral CYC, even when administered for less than 6 months, causes diminished ovarian reserve, as indicated by low AMH levels. These data highlight the need for alternative treatments for GPA in women of childbearing age.

AB The outcomes in children with refractory/relapsed (R/R) acute lymphoblastic leukemia (ALL) are dismal. The efficacy and safety of intravenous clofarabine 40 mg/m(2) per day, cyclophosphamide 440 mg/m(2) per day, and etoposide 100 mg/m(2) per day for 5 consecutive days in pediatric patients with R/R ALL was evaluated in this phase 2 study. The primary endpoint was overall response rate (complete remission [CR] plus CR without platelet recovery [CRp]). Among the 25 patients (median age, 14 years; pre-B cell ALL, 84%; >= 2 prior regimens: 84%; refractory to previous regimen: 60%), the overall response rate was 44% (7 CR, 4 CRp) with a 67.3-week median duration or remission censored at last follow-up. Most patients proceeded to alternative therapy, and 10 patients (40%) received hematopoietic stem cell transplantation. Six patients (24%) died because of treatment-related adverse events associated with infection, hepatotoxicity, and/or multiorgan failure. The study protocol was amended to exclude patients with prior hematopoietic stem cell transplantation after 4 of the first 8 patients developed severe hepatotoxicity suggestive of veno-occlusive disease. No additional cases of veno-occlusive disease occurred. The regimen offered encouraging response rates and sustained remission in R/R patients. Future investigation should include exploration of patient selection, dosing, and supportive care. This trial was registered at www.clinicaltrials.gov as #NCT00315705. (Blood. 2011;118(23):6043-6049)

TI Implementing a systems-oriented morbidity and mortality conference in
remote rural Nepal for quality improvement
SO BMJ QUALITY & SAFETY
LA English
DT Article
ID DEPARTMENTS; AUDIT; ERROR
AB Problem: In hospitals in rural, resource-limited settings, there is an acute need for simple, strategies to improve healthcare quality.
Setting: A district hospital in remote western
Key measures for improvement: To provide a mechanism for systems-level reflection so that can identify targets for quality improvement in healthcare delivery.
Strategies for change: To develop a morbidity and mortality conference (M&M) quality improvement initiative that aims to facilitate structured analysis patient care and identify barriers to providing care, which can subsequently be improved.
Design: The authors designed an M&M involving clinical and non-clinical staff in conducting root-cause analyses of healthcare delivery at their hospital. Weekly conferences focus on seven domains of analysis: operations, supply chain, equipment, personnel, outreach, societal, and structural. Each conference focuses on assessing the care provided, and identifying ways in which services can be improved in the future.
Effects of change: Staff reception of the M&Ms positive. In these M&Ms, staff identified problem in healthcare delivery and steps for improvement. Subsequently, changes were made in hospital workflow, supply procurement, and on-site training.
Lessons learnt: While widely practiced throughout the world, M&Ms typically do not involve both and non-clinical staff members and do not take a systems-level approach. The authors' experience suggests that the adapted M&M conference is a simple, feasible tool for quality improvement in resource-limited settings. Senior managerial commitment is crucial to ensure successful implementation of M&Ms, given the challenging logistics of implementing these programmes in resource-limited health facilities.

AB Although laboratory studies linked zinc and heme iron to colorectal cancer, epidemiologic evidence is limited. We prospectively examined these associations in the Nurses' Health Study and Health Professionals Followup Study. We used Cox proportional hazards regression analyses to calculate cohort-specific relative risks (RRs) and pooled results using a fixed-effects model. We documented 2,114 incident colorectal cancer cases during up to 22 years of follow-up. Compared highest to lowest quintile of dietary zinc intake, the pooled multivariable RRs (95% CIs) were 0.86 (0.73, 1.02) for colorectal cancer, 0.92 (0.76, 1.11) for colon cancer, and 0.68 (0.47, 0.99) for rectal cancer. The significant inverse association between dietary zinc intake and risk of rectal cancer was mainly driven by data in women, although the difference in the sex-specific results was not statistically significant. For the same comparison, the pooled multivariable RRs (95% CIs) for heme iron were 1.10 (0.93, 1.30) for colorectal cancer, 1.06 (0.88, 1.29) for colon cancer, and 1.20 (0.83, 1.75) for rectal cancer. These associations were not significantly modified by alcohol consumption, body mass index, physical activity, menopausal status, or postmenopausal hormone use. Total zinc intake, total iron intake, dietary iron intake, and zinc or iron supplement uses were largely not associated with colorectal cancer risk. Our study does not support strong roles of zinc and heme iron intake in colorectal cancer risk; however, a suggestive inverse association of dietary zinc intake with rectal cancer risk in women requires further study.

AB Purpose To investigate the hypothesis that non-steroidal anti-inflammatory drugs (NSAIDs) lower lung cancer risk.
Methods We analysed pooled individual-level data from seven case-control and one cohort study in the International Lung Cancer Consortium (ILCCO). Relative risks for lung cancer associated with self-reported history of aspirin and other NSAID use were estimated within individual studies using logistic regression or proportional hazards models, adjusted for packyears of smoking, age, calendar period, ethnicity and education and were combined using random effects meta-analysis.
Results A total of 4,309 lung cancer cases (mean age at diagnosis 65 years, 45% adenocarcinoma and 22% squamous-cell carcinoma) and 58,301 non-cases/controls were included. Amongst controls, 34% had used NSAIDs in the past (81% of them used aspirin). After adjustment for negative confounding by smoking, ever-NSAID use (affirmative answer to the study-specific question on NSAID use) was associated with a 26% reduction (95% confidence interval 8 to 41%) in lung cancer risk in men, but not in women (3% increase (-11% to 30%)). In men, the association was stronger in current and former smokers, and for squamous-cell carcinoma than for adenocarcinomas, but there was no trend with duration of use. No differences were found in the effects on lung cancer risk of aspirin and non-aspirin NSAIDs.
Conclusions Evidence from ILCCO suggests that NSAID use in men confers a modest protection for lung cancer, especially amongst ever-smokers. Additional investigation is needed regarding the possible effects of age, duration, dose and type of NSAID and whether effect modification by smoking status or sex exists.

AB Purpose Case-control studies suggest increased sun exposure reduces non-Hodgkin lymphoma (NHL) risk. Evidence from prospective cohort studies, however, is limited and inconsistent. We evaluated the association between ambient ultraviolet radiation (UV) exposure and NHL in a nationwide cohort of women, the Nurses' Health Study (NHS).
Methods Between 1976 and 2006, we identified 1064 incident NHL cases among 115,482 women in the prospective NHS. Exposures assessed included average annual UV-B flux based on residence at various times during life, vitamin D intake, and predicted plasma 25-hydroxyvitamin D levels. We estimated incidence rate ratios (RRs) and 95% confidence intervals (CIs) for risk of all NHL and histologic subtypes using Cox proportional hazards models.
Results NHL risk was increased for women residing in areas of high ambient UV radiation (UV-B flux >113 R-B count x 10(-4)) compared to those with lower exposure (<113), with positive linear trends at all time points. The multivariable-adjusted RR for high UV area at age 15 was 1.21 (95% CI: 1.00, 1.47; p-trend < 0.01). There was no evidence of statistical heterogeneity by subtype, although power was limited for subtype analyses. We observed no association between vitamin D measures and risk of NHL overall or by subtype.
Conclusions Our findings do not support the hypothesis of a protective effect of UV radiation exposure on NHL risk. We found no association between vitamin D and NHL risk.

AB 1. Putative physiological functions of human epicardial adipose tissue (EAT) include: (i) lipid storage for the energy needs of the myocardium; (ii) thermoregulation, whereby brown fat components of EAT generate heat by non-shivering thermogenesis in response to core cooling; (iii) neuroprotection of the cardiac autonomic ganglia and nerves; and (iv) regulation of vasomotion and luminal size of the coronary arteries. Under pathophysiological circumstances, EAT may play an adverse paracrine role in cardiac arrhythmias and in lipotoxic cardiomyopathy, but of major current interest is its hypothetical role as an immunological organ contributing to inflammation around coronary artery disease (CAD).

AB Biochemical markers of bone turnover provide insight into ongoing rates of skeletal metabolism and tumor-bone interactions in patients with malignant bone disease. This article reviews the available recent evidence assessing the potential of bone markers for detecting and monitoring malignant bone lesions in patients with advanced cancers, and for assessing overall skeletal health and response to antiresorptive therapies in patients at all stages of cancer progression. Most data thus far are for urinary N-terminal cross-linked telopeptide of type I collagen (NTX) in predicting risks of skeletal morbidity and death and monitoring response to zoledronic acid in patients with bone metastases. Ongoing studies are evaluating such correlations for other markers and therapies. Emerging evidence suggests that bone markers may help identify patients at high risk for bone metastasis or bone lesion progression, thereby allowing improved follow-up. Results from ongoing clinical trials evaluating such potential applications of bone markers are awaited. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

AB Background Although the overall incidence of hepatitis B virus (HBV) has declined since the introduction of universal vaccine guidelines, the incidence remains elevated in high risk groups. Recent guidelines from the Centers for Disease Control (CDC) have underscored the importance of vaccination against HBV in high risk individuals. However, the incidence of HBV in this group remains elevated, suggesting underuse of vaccinations by healthcare providers.
Aim The purpose of this study was to measure practice patterns of HBV vaccination, and identify predictors of vaccination underuse.
Methods We created a survey with four vignettes describing patients at high risk for contracting HBV, followed by questions regarding knowledge, attitudes, and beliefs (KAB) of HBV screening and vaccination. A random sample of 1,000 physicians, including internists, family medicine, OB/GYN, gastroenterologists, and experts in HBV epidemiology were surveyed. Regression analysis on composite guideline adherence scores identified KAB profiles that predict scores.
Results On average, responders endorsed 71% of the CDC HBV vaccination guidelines. There were three predictors of diminished screening proclivity: (1) younger provider age (P = 0.028), (2) lower awareness that adult HBV is contracted primarily through heterosexual sex (P = 0.023), and (3) being a provider other than a gastroenterologist (P = 0.009).
Conclusions Respondents endorsed most-but not all-CDC supported HBV screening practices. Lower adherence was predicted by specific and modifiable KAB profiles, and by younger age. Future efforts to improve adherence should target trainees, emphasize the importance of obtaining sexual histories in high risk patients, and inform that HBV is predominantly a heterosexually transmitted infection.

AB Thyroid fine needle aspiration (FNA) is a safe, cost effective, and relatively accurate method for guiding the initial management of a thyroid nodule. The popularity of thyroid FNA is reflected in the fact that over 350,000 thyroid FNAs are performed each year in the USA. As we move into the next decade, several issues pertaining to thyroid FNA are being addressed including: how to better apply thyroid FNA as a differential test for follicular-patterned thyroid tumors, how to manage the atypical thyroid FNA, and how to use thyroid FNA in the evaluation of poorly differentiated thyroid carcinomas.

AB Aims To describe the incidence of dyspnoea and its associations with demographic characteristics and clinical outcomes in patients with acute coronary syndromes (ACS) treated with ticagrelor or clopidogrel in the PLATelet inhibition and patient Outcomes (PLATO) study.
Methods and results In the PLATO study, 18 624 patients were randomized to receive either clopidogrel [300-600 mg loading dose (LD), 75 mg daily] or ticagrelor (180 mg LD, 90 mg b.i.d.). The occurrence of reported dyspnoea adverse events (AEs) was analysed in the 18 421 patients who received at least one dose of study medication in relation to demographic characteristics, clinical outcomes and other associations of patients with and without dyspnoea. A total of 1339 ticagrelor-treated patients (14.5%) and 798 clopidogrel-treated patients (8.7%) had a dyspnoea AE following randomization, with respectively 39 (0.4%) and 24 (0.3%) classified as severe in intensity. Excluding dyspnoea AEs occurring after the secondary endpoint of myocardial infarction (MI), the yearly rates of the efficacy endpoints in dyspnoea AE patients in the ticagrelor and clopidogrel groups were: for the primary composite of CV death, MI, and stroke, 8.8 and 10.4% (unadjusted P = 0.25; adjusted P = 0.54); for CV death, 3.1 and 4.8% (unadjusted P = 0.024; adjusted P = 0.18); and for total death 3.7 and 6.2% (unadjusted P = 0.004; adjusted P = 0.06), respectively.
Conclusions Ticagrelor-related dyspnoea is usually mild or moderate in intensity and does not appear to be associated with differences concerning any efficacy or safety outcomes with ticagrelor compared with clopidogrel therapy in ACS patients.

ID PANETH CELLS; INNATE; PEPTIDOGLYCAN; DISEASE; GENE
AB Nod2 belongs to the nucleotide-binding domain leucine-rich repeat family of proteins and senses bacterial cell wall components to initiate innate immune responses against various pathogens. Recently, it has been reported that T-cell-intrinsic expression of Nod2 promotes host defense against Toxoplasma gondii infection by inducing type 1 immunity. Here, we present results that demonstrate that Nod2 does not play a role in the defense against T. gondii infection. Nod2-deficient mice were fully capable of inducing Th1 immune responses and did not show enhanced susceptibility to infection. Upon TCR stimulation in vitro, Nod2-deficient CD4(+) T cells showed normal activation, IL-2 production, proliferation, and Th1/2 differentiation. Nod2 mRNA and protein were expressed in CD4(+) T and CD8(+) T cells at substantial levels. Therefore, Nod2, although expressed in CD4(+) T cells, does not have an intrinsic function in T-cell activation and differentiation.

AB Despite ongoing improvements in resuscitation, care, and outcomes, traumatic injury remains a significant health care and economic burden. The causes are multifactorial, but our approach to the clinical management of these patients remains limited by our current understanding of the pathobiology of the disease. A multicenter, multidisciplinary program known as the "Inflammation and the Host Response to Injury" Large Scale Collaborative Research Program was created by the National Institute of General Medical Sciences (NIGMS, U54 GM062119-10) in 2001 in a 10-year effort to address some of these issues. Its primary goal is to describe the human genomic response to severe trauma and burns, and to examine changes in gene expression in the context of different clinical outcomes. The Program has not only successfully implemented clinical care guidelines for managing the severe trauma patient based on the best available evidence to minimize iatrogenic variability, but it has also examined the genome-wide, immune-inflammatory response in total and isolated blood leukocyte populations. This review will address current milestones as well as future directions for the Program.

AB Patients treated postoperatively in surgical intensive care units often receive delayed enteral nutrition. We hypothesized that the introduction of guidelines promoting early enteral nutrition is associated with earlier enteral feeding.
Enteral nutrition guidelines were created by the consensus of a multidisciplinary team consisting of intensivists, nurses, nutritionists, and surgeons. The guidelines were implemented through repeated staff education. We prospectively compared data on nutritional support in the surgical intensive care unit of a tertiary care center before (pre-intervention period, from January 27 to April 30, 2008) and after (post-intervention period, from May 1st to August 15th, 2008) implementation of the guidelines. The primary outcome was time to enteral feeding (oral or tube feeding).
146 patients were evaluated during the pre-period and 141 patients during the post-period. Patients during the two time periods had similar demographics and clinical characteristics. None of the patients were without nutrition for longer than 7 days. Oral or feeding tube nutrition was started earlier in the post-period (median 1 vs. 2 days, p < 0.001). There was no difference in the percentages of patients receiving parenteral nutrition (7.4 vs. 10%, p = 0.360). There was no increase in aspiration events in the post-period (8 vs. 9.4%, p = 0.606).
Introduction of guidelines to facilitate enteral nutrition in a surgical intensive care unit was associated with earlier enteral feeding.

AB The adaptive landscape and the G-matrix are keys concepts for understanding how quantitative characters evolve during adaptive radiation. In particular, whether the adaptive landscape can drive convergence of phenotypic integration (i.e., the pattern of phenotypic variation and covariation summarized in the P-matrix) is not well studied. We estimated and compared P for 19 morphological traits in eight species of Caribbean Anolis lizards, finding that similarity in P among species was not correlated with phylogenetic distance. However, greater similarity in P among ecologically similar Anolis species (i.e., the trunk-ground ecomorph) suggests the role of convergent natural selection. Despite this convergence and relatively deep phylogenetic divergence, a large portion of eigenstructure of P is retained among our eight focal species. We also analyzed P as an approximation of G to test for correspondence with the pattern of phenotypic divergence in 21 Caribbean Anolis species. These patterns of covariation were coincident, suggesting that either genetic constraint has influenced the pattern of among-species divergence or, alternatively, that the adaptive landscape has influenced both G and the pattern of phenotypic divergence among species. We provide evidence for convergent evolution of phenotypic integration for one class of Anolis ecomorph, revealing yet another important dimension of evolutionary convergence in this group.

AB Principal strata are defined by the potential values of a post-treatment variable, and a principal effect is a causal effect within a principal stratum. Identifying the principal effect within every principal stratum is quite challenging. In this paper, we propose an approach for identifying principal effects on a binary outcome via a pre-treatment covariate. We prove the identifiability with single post-treatment intervention under the monotonicity assumption. Furthermore, we discuss the local identifiability with multicomponent intervention. Simulations are performed to evaluate our approach. We also apply it to a real data set from the Improving Mood-Promoting Access to Collaborate Treatment program.

AB We describe implementation of a set-based method to assess the significance of findings from genomewide association study data. Our method, implemented in PLINK, is based on theoretical approximation of Fisher's statistics such that the combination of P-vales at a gene or across a pathway is carried out in a manner that accounts for the correlation structure, or linkage disequilibrium, between single nucleotide polymorphisms. We compare our method to a permutation-based product of P-values approach and show a typical correlation in excess of 0.98 for a number of comparisons. The method gives Type I error rates that are less than or equal to the corresponding nominal significance levels, making it robust to the effects of false positives. We show that in broadly similar populations, reference data sets of markers are an appropriate substrate for deriving marker-marker linkage disequilibrium (LD), negating the need to access individual level genotypes, greatly facilitating its generic applicability. We show that the method is thus robust to LD-associated bias and has equivalent performance to permutation-based methods, with a significantly shorter runtime. This is particularly relevant at a time of increasing public availability of significantly larger genetic data sets and should go a long way to assist in the rapid analysis of these data sets. Genet.

AB Purpose. To identify prognostic and predictive factors of overall survival (OS), relapse-free survival (RFS) and toxicity for patients with uterine papillary serous carcinoma (UPSC).
Materials and methods. Patient, tumor, treatment and relapse characteristics of 135 women with Stages I-IVA UPSC treated between 1980 and 2006 at Dana-Farber/Brigham and Women's Cancer Center (DF/BWCC) were analyzed using Cox regression models to determine prognostic and predictive factors for OS. RFS and toxicity.
Results. Mean follow-up was 5.5 years (range, 0.01-25.2). Median 5-year OS was 52%, and RFS was 42% for all patients. On Cox regression analysis, increasing age, stage, and myometrial invasion were prognostic factors associated with shorter OS and RFS. A paclitaxel-platinum chemotherapy regimen was significantly associated with longer OS (hazard ratio [HR] = 0.34, 95% confidence interval [CI] 0.15-0.74, p = 0.007) and RFS (HR = 0.45, 95% CI 0.22-0.92, p = 0.03). RFS was improved for patients treated with RT (HR = 0.44, 95% CI 0.25-0.77, p = 0.004). The 5-year grade 3+ toxicity rate was 3.5% for those who received RT and was 2.9% for those who did not (p = NS).
Conclusion. Uterine papillary serous cancer can be an aggressive tumor type with a poor prognosis. RFS was improved by radiation and chemotherapy with few grade 3 or higher complications. Using radiation and paclitaxel-platinum chemotherapy should be attempted whenever feasible for patients with UPSC who do not have distant metastases at diagnosis. (C) 2011 Elsevier Inc.

AB BLT mice, constructed by surgical implantation of human fetal thymus-liver tissues and intravenous delivery of autologous CD34(+) haematopoietic stem cells into adult non-obese diabetic/severe combined immunodeficiency mice, were evaluated for vaccine-induced humoral immune responses. Following engraftment, these mice developed a human lymphoid system; however, the majority of the peripheral human B lymphocytes displayed an immature phenotype as evidenced by surface CD10 expression. Over 50% of the human B cells in the periphery but not in the bone marrow also expressed the CD5 antigen, which is found only infrequently on mature follicular B cells in humans. A single intramuscular immunization with recombinant viral envelope antigens, e. g. HIV-gp140 and West Nile Virus envelope proteins, together with the immune stimulatory IC31 (R) adjuvant resulted in seroconversion characterized by antigen-specific human antibodies predominantly of the IgM isotype. However, repeated booster immunizations did not induce secondary immune responses as evidenced by the lack of class switching and specific IgM levels remaining relatively unchanged. Interestingly, the peripheral CD19(+) CD5(+) but not the CD19(+) CD5(-) human B lymphocytes displayed a late developing CD27(+) IgM(+) memory phenotype, suggesting that the CD5(+) B-cell subset, previously implicated in 'natural antibody' production, may play a role in the vaccine-induced antibody response. Furthermore, human T lymphocytes from these mice demonstrated suboptimal proliferative responses and loss of co-stimulatory surface proteins ex vivo that could be partially reversed with human interleukin-2 and interleukin-7. Therefore, vaccine-induced immune responses in BLT mice resemble a T-cell-independent pathway that can potentially be modulated in vivo by the exogenous delivery of human cytokines/growth factors.

AB Purpose Although limited data exist on the efficacy and potential risk of synergistic aminoglycoside therapy for persistent Staphylococcus aureus bacteremia and endocarditis, aminoglycosides are frequently used in clinical practice.
Methods As our study population, we included subjects fulfilling the modified Duke criteria for S. aureus endocarditis and/or having greater than 72 h of S. aureus bacteremia. Among these subjects, we compared patients who did and did not receive aminoglycoside therapy for their S. aureus bloodstream infection. These groups were compared for the primary outcome of recurrent bacteremia, as well as for the duration of bacteremia, mortality, complication rate, and incident renal failure.
Results Eighty-seven subjects fulfilled the inclusion criteria. Of these, 49 received aminoglycoside therapy, whereas 38 did not. There were no significant differences in the baseline characteristics when comparing groups who did or did not receive aminoglycoside therapy. Four (8.2%) subjects treated with aminoglycoside therapy experienced recurrent bacteremia versus nine (23.7%) who did not receive aminoglycoside therapy [relative risk and 95% confidence interval [RR (95% CI)] = 0.51 (0.22-1.17), p = 0.04]. In multivariable analyses, aminoglycoside use remained significantly associated with a decrease in recurrent bacteremia [adjusted odds ratio (OR) (95% CI) = 0.26 (0.07-0.98), p = 0.046]. No significant differences were seen between groups treated with and without an aminoglycoside in terms of the 6-month all-cause mortality (51.0 vs. 42.1%, p = 0.41), complication rate (71.4 vs. 73.7%, p = 0.82), or incident renal failure (54.5 vs. 46.9%, p = 0.54).
Conclusions The use of combination therapy with an aminoglycoside in persistent S. aureus bacteremia and/or endocarditis may be associated with a lower rate of recurrent bacteremia without significant differences in the incident renal failure.

AB Background: We developed a series of dendritic cell autoimmune modulators (DCAMs) based on small molecule Flt3 receptor tyrosine kinase inhibitors (TKIs) for the inhibition of intestinal inflammation and oral delivery.
Methods: DCAMs were administered orally during and after induction of dextran sodium sulfate (DSS)-induced colitis. Dendritic cell recruitment and inflammatory responses were determined in the mucosal immune system during acute intestinal inflammatory responses and mucosal recovery. Bone marrow-derived macrophages were utilized to define the mechanisms by which DCAMs can modify responses to microbial signals.
Results: Oral doses of DCAMs prevented severe weight loss and mucosal inflammation associated with DSS colitis in mice. The presence of DCAMs increased the number of CD11c(+)PDCA1(+) dendritic cells, induced interleukin (IL)-10 expression, and reduced inflammatory cytokine expression in the mucosal immune system. Surprisingly, DCAMs regulated innate immune responses in macrophages resulting in the inhibition of tumor necrosis factor alpha (TNF-alpha) production and the induction of IL-10 expression during Toll-like receptor-mediated signaling.
Conclusions: We identified two new imidazoacridinone derivatives that protect mice from severe colitis and promote mucosal recovery by enhancing protective cytokine production while inhibiting proinflammatory stimuli during microbial recognition. These compounds are promising candidates for further development into potent orally available drugs for the prevention of colitis and promotion of mucosal recovery.

AB Background: Focally enhanced gastritis has been described in association with Crohn's disease and ulcerative colitis, but is rare in the general population. The study aim was to test whether idiopathic colitis in macaques was associated with any characteristic changes of the gastric mucosa resembling similar changes in humans.
Methods: The presence or absence of idiopathic colitis was established by gross and microscopic examination of the colons of rhesus macaques (Macaca mulatta), which died at the Oregon National Primate Research Center. Gastric tissue specimens were compared between a case population of 26 macaques with idiopathic colitis and a control population of 21 macaques without colitis. The specimens were histologically assessed by two independent pathologists blinded to the presence or absence of idiopathic colitis. Differences between cases and controls were compared using a two-sided Fisher's exact test.
Results: Of the 26 cases of macaques with colitis, 11 animals (42%) harbored signs of chronic gastritis. Of the 21 control macaques without colitis, nine animals (43%) harbored signs of chronic gastritis, P = 1.0000. Of all animals with gastritis, 1/11 animals with colitis and 2/9 control animals showed rare active gastritis as evidenced by the presence of neutrophils, P = 0.5658. Lymphocytic infiltrates of the gastric mucosa were seen in 4/11 colitis cases and 0/9 controls, P = 0.0942. No gastric specimens with focally enhanced gastritis were found among any of the case or control animals.
Conclusions: Unlike chronic inflammatory bowel disease in humans, idiopathic colitis in macaques is not associated with focally enhanced gastritis or any other type of specific gastritis. (Inflamm Bowel Dis 2011;17:2456-2461)

AB Eukaryotic cells undergo rapid regulatory processes to maintain cellular homeostasis upon osmotic stress. In fishes, gill epithelial cells play main roles in these processes. Although osmoregulatory functions of fish gills have been well studied, little is known about the underlying mechanisms, particularly the hypertonic-induced signalling pathways during osmotic stress. This study reports for the first time on the osmo-sensing signal cascade that related to the medaka osmotic stress transcription factor 1 (Ostf1), a hypertonic induced immediate early gene, under hypertonic stress. Quantitative real-time PCR showed the rapid increase of Ostf1 in gill after transfer of medaka from fresh water to 50% seawater; particularly Ostf1b whose mRNA expression increased to 4 folds at 0.5 h and reached to 10 folds at 6 h after the transfer. The in vivo knockdown of Ostf1b profoundly inhibited SEK and JNK phosphorylation, but not p38 and ERK phosphorylation in the medaka gill tissue. To further investigate the possible role of Ostf1b in the JNK pathway, Ostf1b was ectopically expressed in HEK293 cells. Results indicated that Ostf1b is a downstream target of SEK and JNK and exerts a positive feedback loop on the JNK signalling pathway via activation of GCK and/or MLK3 proteins. Additionally, MAPK inhibitors experiments suggested that activation of the JNK pathway by hypertonicity is involved in the maintenance of Ostf1b stability, which in turn provides continuous stimulation of GCK for JNK phosphorylation. Lastly, changes in transcription levels of different water/ion transporters were found in knockdown or ecoptic over-expression of Ostf1b in medaka gills and human embryonic kidney cells, suggesting the role of Ostf1b in modulation of critical water channel/ion transporters during osmotic stress.

AB There is no good animal model of large artery injury-induced intimal hyperplasia (IH). Those available are reproducible, providing only a few layers of proliferating cells or have the disadvantage of the presence of a metallic stent that complicates histology evaluation. This study was designed to develop a new, simple model of accelerated IH based on balloon injury in conjunction with disruption of the Internal Elastic Lamina (IEL) in pig external iliac arteries. Iliac artery injury (n = 24) was performed in 12 Yorkshire pigs divided in two groups: Group I (n = 10), overdistention injury induced by an oversized non-compliant balloon; Group II (n = 14), arterial wall disruption by pulling back an isometric cutting balloon (CB) followed by stretching with a compliant Fogarty Balloon (FB). At two weeks, arteries were processed for morphometric analysis and immunohistochemistry (IHC) for smooth muscle cells (SMC) and proliferating cell nuclear antigen (PCNA). When comparing the two groups, at 2 weeks, arteries of group II had a higher incidence of IH (100% vs. 50%, P = 0.0059), increased intimal areas (2.54 +/- 0.33 mm(2) vs. 0.93 +/- 0.36 mm(2), P = 0.004), increased intimal area/Media area ratios (0.95 +/- 0.1 vs. 0.28 +/- 0.05; P < 0.0001) and decreased lumen areas (6.24 +/- 0.44 vs. 9.48 +/- 1.56, P = 0.026). No thrombosis was noticed in Group II. Neointima was composed by proliferating SMC located with the highest concentration in the area of IEL disruption (IHC). Arterial injury by pulling back CB and FB induces significant IH in pig iliac arteries by two weeks without thrombosis. This model is superior to the classical overdistention non-compliant model and should be useful and cost-effective for preclinical testing of procedures designed to inhibit IH in large peripheral arteries.

AB Objective: To explore perceptions of cesarean delivery and patient-provider communication surrounding female circumcision and childbirth through interviews with Somali women residing in the USA. Methods: Semistructured in-depth interviews were conducted with 23 Somali immigrant women living in Boston who had given birth in the USA and Africa. Interviews asked about birth experiences in the USA and Africa, as well as norms and attitudes surrounding childbirth practices. Interview transcripts were coded and themes identified through an iterative process. Results: Participants were aged 25-52 years and had been living in the USA for an average of 7 years. All women had experienced circumcision. Five women had undergone a cesarean delivery. Women feared having a cesarean because of their perception that it could result in death or disability. Women also highlighted that providers in the USA rarely discussed female circumcision or how it could affect childbirth experiences. Conclusions: Previous experiences and cultural beliefs can affect how Somali immigrant women understand labor and delivery practices in the USA and can explain why some women are wary of cesarean delivery. Educating providers and encouraging patient-provider communication about cesarean delivery and female circumcision can ease fears, increase trust, and improve birth experiences for Somali immigrant women in the USA.

AB Purpose: Several accelerated partial breast irradiation (APBI) techniques are described in the literature, and apparently, the three-dimensional (3D)-conformal technique is being used increasingly. Nonetheless, the optimal radiation dose is not yet known. Here, we report feasibility and early toxicities of APBI delivering 40 Gy over 5 days, in a phase II trial.
Methods and Materials: From October 2007 to September 2008, 25 patients with pT1N0 cancer received 3D-conformal APBI. The prescribed radiation dose was 40 Gy in 4-Gy fractions given twice daily. This technique used two minitangents and an "en face" electron field. Toxicities were systematically assessed at 1, 2, and 6 months and then once every 6 months.
Results: The planning tumor volume for evaluation (PTV_EVAL) coverage was adequate: the mean dose to the PTV_EVAL was 41.8 Gy (range, 41-42.4 Gy). Mean doses to the ipsilateral lung and heart were 1.6 Gy (range, 1.0-2.3 Gy) and 1.2 Gy (range, 1.0-1.6 Gy), respectively. One and two months after completion of APBI, most patients had no or mild erythema (n = 16 patients at 1 month; n = 25 patients at 2 months); none of these patients developed moist desquamation. After a median follow-up of 12 months, only 1 patient had a significant moderate field contracture (grade 2). Other reported late toxicities were grade 1.
Conclusions: 3D-conformal APBI (with two minitangents and an "en face" electron field) using a total dose of 40 Gy in 10 fractions twice daily over 5 days achieved appropriate PTV_EVAL coverage and offered significant sparing of normal tissue. Early tolerance was excellent. (C) 2011 Elsevier Inc.

AB Purpose: In this study, we report the clinical outcomes of 7 children with bladder/prostate rhabdomyosarcoma (RMS) treated with proton radiation and compare proton treatment plans with matched intensity-modulated radiation therapy (IMRT) plans, with an emphasis on dose savings to reproductive and skeletal structures.
Methods and Materials: Follow-up consisted of scheduled clinic appointments at our institution or direct communication with the treating physicians for referred patients. Each proton radiotherapy plan used for treatment was directly compared to an BIRT plan generated for the study. Clinical target volumes and normal tissue volumes were held constant to facilitate dosimetric comparisons. Each plan was optimized for target coverage and normal tissue sparing.
Results: Seven male patients were treated with proton radiotherapy for bladder/prostate RMS at the Massachusetts General Hospital between 2002 and 2008. Median age at treatment was 30 months (11-70 months). Median follow-up was 27 months (10-90 months). Four patients underwent a gross total resection prior to radiation, and all patients received concurrent chemotherapy. Radiation doses ranged from 36 cobalt Gray equivalent (CGE) to 50.4 CGE. Five of 7 patients were without evidence of disease and with intact bladders at study completion. Target volume dosimetry was equivalent between the two modalities for all 7 patients. Proton radiotherapy led to a significant decrease in mean organ dose to the bladder (25.1 CGE vs. 33.2 Gy; p = 0.03), testes (0.0 CGE vs. 0.6 Gy; p = 0.016), femoral heads (1.6 CGE vs. 10.6 Gy; p = 0.016), growth plates (21.7 CGE vs. 32.4 Gy; p = 0.016), and pelvic bones (8.8 CGE vs. 13.5 Gy; p = 0.016) compared to IMRT.
Conclusions: This study provides evidence of significant dose savings to normal structures with proton radiotherapy compared to IMRT and is well tolerated in this patient population. The long-term impact of these reduced doses can be tested in future studies incorporating extended follow-up, objective outcome measures, and quality-of-life analyses. (C) 2011 Elsevier Inc.

AB Purpose: To determine the maximum tolerated dose (MTD) of tipifarnib in combination with conventional radiotherapy for patients with newly diagnosed glioblastoma. The MTD was evaluated in three patient cohorts, stratified based on concurrent use of enzyme-inducing antiepileptic drugs (EIAED) or concurrent treatment with temozolomide (TMZ): Group A: patients not receiving EIAED and not receiving TMZ; Group A-TMZ: patients not receiving EIAED and receiving treatment with TMZ; Group B: any patients receiving EIAED but not TMZ.
Patients and Methods: After diagnostic surgery or biopsy, treatment with tipifarnib started 5 to 9 days before initiating radiotherapy, twice daily, in 4-week cycles using discontinuous dosing (21 out of 28 days), until toxicity or progression. For Group A-TMZ, patients also received TMZ daily during radiotherapy and then standard 5/28 days dosing after radiotherapy. Dose-limiting toxicity (DLT) was determined over the first 10 weeks of therapy for all cohorts.
Results: Fifty-one patients were enrolled for MTD determination: 10 patients in Group A, 21 patients in Group A-TMZ, and 20 patients in Group B. In the Group A and Group A-TMZ cohorts, patients achieved the intended MTD of 300 mg twice daily (bid) with DLTs including rash and fatigue. For Group B, the MTD was determined as 300 mg bid, half the expected dose. The DLTs included rash and one intracranial hemorrhage. Thirteen of the 20 patients evaluated in Group A-TMZ were alive at 1 year.
Conclusion: Tipifarnib is well tolerated at 300 mg bid given discontinuously (21/28 days) in 4-week cycles, concurrently with standard chemo/radiotherapy. A Phase II study should evaluate the efficacy of tipifarnib with radiation and TMZ in patients with newly diagnosed glioblastoma and not receiving EIAED. (C) 2011 Elsevier Inc.

AB Purpose: Given the excellent prognosis for patients with benign meningiomas, treatment strategies to minimize late effects are important. One strategy is proton radiation therapy (RT), which allows less integral dose to normal tissue and greater homogeneity than photon RT. Here, we report the first series of proton stereotactic radiosurgery (SRS) used for the treatment of meningiomas.
Methods and Materials: We identified 50 patients with 51 histologically proven or image- defined, presumed-benign meningiomas treated at our institution between 1996 and 2007. Tumors of < 4 cm in diameter and located >= 2 mm from the optic apparatus were eligible for treatment. Indications included primary treatment (n = 32), residual tumor following surgery (n = 8), and recurrent tumor following surgery (n = 10). The median dose delivered was 13 Gray radiobiologic equivalent (Gy[RBE]) (range, 10.0-15.5 Gy[RBE]) prescribed to the 90% isodose line.
Results: Median follow-up was 32 months (range, 6-133 months). Magnetic resonance imaging at the most recent follow-up or time of progression revealed 33 meningiomas with stable sizes, 13 meningiomas with decreased size, and 5 meningiomas with increased size. The 3-year actuarial tumor control rate was 94% (95% confidence interval, 77%-98%). Symptoms were improved in 47% (16/34) of patients, unchanged in 44% (15/34) of patients, and worse in 9% (3/34) of patients. The rate of potential permanent adverse effects after SRS was 5.9% (3/51 patients).
Conclusions: Proton SRS is an effective therapy for small benign meningiomas, with a potentially lower rate of long-term treatment-related morbidity. Longer follow-up is needed to assess durability of tumor control and late effects. (C) 2011 Elsevier Inc.

AB Hereditary sensory and autonomic neuropathy type 1 (HSAN1) causes sensory loss that predominantly affects the lower limbs, often preceded by hyperpathia and spontaneous shooting or lancinating pain. It is caused by several missense mutations in the genes encoding 2 of the 3 subunits of the enzyme serine palmitoyltransferase (SPT). The mutant forms of the enzyme show a shift from their canonical substrate L-serine to the alternative substrate L-alanine. This shift leads to increased formation of neurotoxic deoxysphingolipids (dSLs). Our initial analysis showed that in HEK cells transfected with SPTLC1 mutants, dSL generation was modulated in vitro in the presence of various amino acids. We therefore examined whether in vivo specific amino acid substrate supplementation influenced dSL levels and disease severity in HSAN1. In mice bearing a transgene expressing the C133W SPTLC1 mutant linked to HSAN1, a 10% L-serine-enriched diet reduced dSL levels. L-serine supplementation also improved measures of motor and sensory performance as well as measures of male fertility. In contrast, a 10% L-alanine-enriched diet increased dSL levels and led to severe peripheral neuropathy. In a pilot study with 14 HSAN1 patients, L-serine supplementation similarly reduced dSL levels. These observations support: the hypothesis that an altered substrate selectivity of the mutant SPT is key to the pathophysiology of HSAN1 and raise the prospect of L-serine supplementation as a first treatment option for this disorder.

AB Purpose The interpretation of scaphoid anatomy and kinematics is confusing and controversial. This results from a lack of consensus on the anatomy of the ligaments attaching to the scaphoid and an overwhelming variety of substantially different anatomic descriptions and classification systems of the wrist joint in the literature. The present study systemically reviews the consistencies or inconsistencies of the various scaphoid ligament descriptions and aims to clarify and unify different concepts and classification systems.
Methods We performed a systematic search of the medical literature from 1950 to 2010. We included all descriptive reports of the anatomy or morphology of the scaphoid, ligaments, or both. With the aim to describe the best available evidence, we considered all anatomical descriptions but emphasized a selection of the most frequently cited articles.
Results The literature search resulted in 555 potentially eligible descriptive reports, 58 of which met the inclusion criteria and were included in the review. Variations in the anatomic descriptions appear to be mostly due to the difficulty of identifying individual interdigitating ligaments or bundles by macroscopic dissections, as well as the interindividual variability in ligament anatomy. The most important areas of controversy in the scaphoid ligament attachments include the radial collateral ligament, dorsal radiocarpal ligament, dorsal intercarpal ligament, volar scaphotriquetral ligament, and scaphotrapezium-trapezoid ligament.
Conclusions None of the scaphoid ligaments other than the scaphocapitate ligament have been described consistently. Future research is required to verify the ligament attachments that currently have the most controversial descriptions, while addressing the interindividual variability of ligament insertions and morphology.
Clinical relevance Thorough knowledge of the anatomy will enhance our understanding of the kinematics of the scaphoid. (J Hand Surg 2011;36A:1926-1935. Copyright (C) 2011 by the American Society for Surgery of the Hand. All rights reserved.)

AB Efficient clearance of apoptotie cells by phagocytes (efferocytosis) is critical for normal tissue homeostasis and regulation of the immune system. Apoptotic cells are recognized by a vast repertoire of receptors on macrophage that lead to transient formation of phosphatidylinosito1-3,4,5-trisphosphate [PtdIns(3,4,5)P3] and subsequent cytoskeletal reorganization necessary for engulfment. Certain P13K isoforms are required for engulfment of apoptotic cells, but relatively little is known about the role of lipid phosphatases in this process. In this study, we report that the activity of phosphatase and tensin homolog deleted on chromosome 10 (PTEN), a phosphatidylinositol 3-phosphatase, is elevated upon efferocytosis. Depletion of PTEN in macrophage results in elevated PtdIns(3,4,5)P3 production and enhanced phagocytic ability both in vivo and in vitro, whereas overexpression of wild-type.PTEN abrogates this process. Loss of PTEN in macrophage leads to activation of the pleckstrin homology domain-containing guanine-nucleotide exchange factor Vav1 and subsequent activation of Racl GTPase, resulting in increased amounts of F-actin upon engulfment of apoptotic cells. PTEN disruption also leads to increased production of anti-inflammatory cytokine IL-10 and decreased production of proinflammatory IL-6 and TNF-et upon engulfment of apoptotic cells. These data suggest that PTEN exerts control over efferocytosis potentially by regulating PtdIns(3,4,5)P3 levels that modulate Rac GTPase and F-actin reorganization through Vavl exchange factor and enhancing apoptotic cell-induced anti-inflammatory response. The Journal of Immunology, 2011, 187: 5783-5794.

AB We demonstrate integration of ultraporous (99% porous) elements composed of nanoporous forests of vertically aligned carbon nanotubes (VA-CNTs, or VACNTs) in microelectromechanical systems (MEMS), illustrating their use in fluidic applications for biomedical diagnostics. Our method enables definition of high-aspect-ratio (similar to 10(4), heights similar to 100 mu m, and pore spacings similar to 10 nm) nanoporous elements and preserves the VACNT elements' shapes even under flowthrough conditions. The fluid permeability of the VACNT elements is measured experimentally and shown to be comparable to that of much larger micro-and macroscopic porous materials. Permeability tailoring of VACNT elements through manipulation of both material and CNT growth process parameters is also experimentally demonstrated. Distinct from solid designs (e. g., Si and polydimethylsiloxane), our approach enables fluid flow both around and through the nanoporous microfluidic elements, hence enhancing isolation efficiency by increased physical interaction between the particles in the flow and the functional elements. Simultaneous multiphysics (chemical and mechanical) and multiscale (several orders of magnitude in size) isolation of bioparticles using microfluidic devices with nanoporous elements is demonstrated as well.

AB The hypothesis is that the mechanical mismatch between brain tissue and microelectrodes influences the inflammatory response. Our unique, mechanically adaptive polymer nanocomposite enabled this study within the cerebral cortex of rats. The initial tensile storage modulus of 5 GPa decreases to 12 MPa within 15 min under physiological conditions. The response to the nanocomposite was compared to surface-matched, stiffer implants of traditional wires (411 GPa) coated with the identical polymer substrate and implanted on the contralateral side. Both implants were tethered. Fluorescent immunohistochemistry labeling examined neurons, intermediate filaments, macrophages, microglia and proteoglycans. We demonstrate, for the first time, a system that decouples the mechanical and surface chemistry components of the neural response. The neuronal nuclei density within 100 mu m of the device at four weeks post-implantation was greater for the compliant nanocomposite compared to the stiff wire. At eight weeks post-implantation, the neuronal nuclei density around the nanocomposite was maintained, but the density around the wire recovered to match that of the nanocomposite. The glial scar response to the compliant nanocomposite was less vigorous than it was to the stiffer wire. The results suggest that mechanically associated factors such as proteoglycans and intermediate filaments are important modulators of the response of the compliant nanocomposite.

AB Approximately one-third of patients with advanced, HER2-positive breast cancer develop brain metastases. A significant proportion of women experience central nervous system (CNS) progression after standard radiation therapy. The optimal treatment in the refractory setting is undefined. This study evaluated the toxicity and efficacy of lapatinib in combination with chemotherapy among patients with HER2-positive, progressive brain metastases. Patients with HER2-positive breast cancer with progressive brain metastases after trastuzumab and cranial radiotherapy were included. The primary endpoint was CNS objective response, defined as a >= 50% volumetric reduction of CNS lesion(s) in the absence of new or progressive CNS or non-CNS lesions, or increasing steroid requirements. The study was closed early after 22 of a planned 110 patients were enrolled due to excess toxicity and lack of efficacy in the lapatinib plus topotecan arm. The objective response rate (ORR) in the lapatinib plus capecitabine arm was 38% (exact 95% confidence interval [CI] 13.9-68.4). No responses were observed in the lapatinib plus topotecan arm. Although the study was stopped prior to full enrollment, some promising indications of CNS activity were noted for lapatinib plus capecitabine. The combination of lapatinib plus topotecan was not active and was associated with excess toxicity.

AB This study aims to investigate the association between prenatal exposure to terbutaline and other beta 2 adrenergic receptor (B2AR) agonists and autism spectrum disorders (ASDs). The methodology used is a case-control study among children born from 1995 to 1999 at Kaiser Permanente Northern California hospitals. Cases (n=291) were children with an ASD diagnosis; controls (n=284) were children without ASDs, randomly sampled and frequency-matched to cases on sex, birth year, and delivery hospital. Exposure to B2AR agonists during 30 days prior to conception and each trimester of pregnancy was ascertained from prenatal medical records and health plan databases. The frequency of exposure to any B2AR agonist during pregnancy was similar for mothers of children with ASD and mothers of controls (18.9% vs. 14.8%, P=0.19). Exposure to B2AR agonists other than terbutaline was not associated with an increased risk for ASDs. However, terbutaline exposure for >2 days during the third trimester was associated with more than a fourfold increased risk for ASDs independent of indication although the limited sample size resulted in an imprecise and nonsignificant effect estimate (OR(adj)=4.4; 95% confidence interval, 0.8-24.6). This analysis does not offer evidence linking B2AR exposure in pregnancy with autism risk. However, exposure to terbutaline during the third trimester for >2 days may be associated with an increased risk of autism. Should this result be confirmed in larger samples, it would point to late pregnancy as an etiologic window of interest in autism risk factor research.

AB Regadenoson myocardial perfusion imaging (MPI) is a useful method for risk assessment. We hypothesized that the heart rate response (HRR) to regadenoson carries incremental prognostic information to that derived from perfusion pattern and left ventricular (LV) ejection fraction (EF).
The study population included 1,156 (60 +/- A 13 years, 46% women, 40% diabetes mellitus, 53% chronic kidney disease) patients. During a follow-up period of 22 +/- A 5 months, 103 patients died (9%). Independent determinants of the HRR included age, gender, race, diabetes mellitus, coronary revascularization, LVEF, use of insulin and aldosterone antagonists. Decreasing HRR was associated with stepwise increase in mortality (log-rank P < .0001). In a Cox proportional model for mortality that adjusted for age, gender, diabetes mellitus, renal disease, and MPI findings, HRR in the lowest quartile was independently associated with fivefold increase in mortality compared to the highest quartile [HR 5.2, 95% CI 2.3-12.0, P < .0001]. Patients with a normal HRR had a relatively low annualized total mortality despite the presence of risk factors. The addition of HRR to traditional MPI findings had a net reclassification improvement of 15%, P = .02.
A blunted HRR to regadenoson is an independent predictor of poor outcome, adds incremental value to MPI, and helps in better risk stratification.

AB The objective of this study was to: (1) determine the distribution of lubricin in the human torn anterior cruciate ligament (ACL) and meniscus; (2) determine the distribution of lubricin in the human intact ACL and meniscus; (3) and identify potential cellular sources of lubricin in these tissues. Ten torn ACLs and six torn menisci were obtained from surgeries; for comparison, 11 intact ACLs and 13 intact menisci were obtained from total knee replacements. Samples were formalin fixed and processed for immunohistochemical staining with a monoclonal antibody for lubricin. In torn ACLs and menisci, lubricin was generally found as a discrete layer covering the torn surface. No surface lubricin staining was found on the transected edges produced during excision. Lubricin was also found on the native surfaces of intact ACLs and menisci. In all tissues, lubricin was found in the matrix and intracellularly. The surface layer of lubricin coating torn edges of ACLs and menisci may interfere with the integrative healing process needed for repair. (C) 2011 Orthopaedic Research Society.

AB Objectives: Pediatric gastrointestinal (GI) biopsies represent a disproportionately large fraction of the mucosal biopsies submitted for pathology evaluation relative to the fraction of pediatric endoscopies performed. We sought to explore the rationale for this large sample volume and identify its diagnostic value.
Patients and Methods: Conceptual value-of-information analysis of 100 sequential colonoscopies, including 770 total biopsy specimens. The diagnostic value of each biopsy was evaluated based on its order of appearance in the model and overall contribution to the pathological classification of the disease.
Results: Current practice standards for pediatric GI biopsies provide no guidance on sampling strategy for nonfocal biopsy of suspected inflammatory diseases, resulting in the collection of a nonstandardized number of individual samples and sampling sites that may vary significantly by clinician and institution. We find that this practice adds little to no diagnostic value over more cost-effective protocols, such as a fewer biopsies overall, or fewer specimens with pooled regional biopsies.
Conclusions: In the absence of clear guidance, pediatric GI clinicians and institutions should explore alternative strategies such as the left-right pooled biopsy protocol (common in adult GI practice), or preferably, a more conservative 4-region protocol covering major anatomical landmarks in the colon for nonfocal pediatric colonic biopsies. This will allow individual practitioners and clinical centers to test the hypothesis, supported by our analysis, that such a reduction in resource utilization will have no measurable impact on the quality of care.

AB Spitz nevi are melanocytic proliferations that are characterized by spindled and/or epithelioid nevomelanocytes. First interpreted as juvenile melanoma, these lesions were later characterized as benign and were observed to affect all age groups. Today, contrasting opinions persist regarding the fundamental benignancy versus malignancy within the spectrum of Spitz tumors. Beyond clinical outcome, this controversy has also been fueled by complex and sometimes convoluted classification schemes based on pathologic characteristics. More recently, immunophenotypic and molecular analyses have begun to clarify the etiologic nature of these tumors. Recent evidence suggests that histopathologic features that suggest more aggressiveness in Spitz tumors relate to mitoses and inflammation. (J Am Acad Dermatol 2011;65:1073-84.)

DIAGNOSIS; PROPOSAL; CHILDHOOD; DIFFICULT; FEATURES; PATIENT
AB For dermatologists, evidence-based management guidelines for Spitz tumors have not been established. Despite the lack of a standardized approach, most dermatologists recommend the excision of Spitz tumors occurring in adults and adopt more conservative measures towards pediatric cases. The histopathologic attributes and the clinical scenario are factored into management in each case. While the metastatic behavior of certain Spitz tumors is well known, the malignant potential of these lesions remains unclear because they only rarely result in negative outcomes. The risks and benefits of adjunctive measures, such as sentinel lymph node biopsy and interferon use, remain untested and are subjects of ongoing controversy. (In part II of this continuing medical education article, we will continue to use the terminology defined in part I for purposes of continuity. "Spitz tumor" is used as the umbrella term for the entire category of lesions, "common Spitz nevi" refers to only the most typical lesions seen in pediatric cases, and "atypical Spitz tumors" encompass the "all other" category, which continues to cause debate.)

AB Background: Quality of life (QoL) for patients with inflammatory skin disease can he significant, but has been evaluated in just one study in dermatomyositis (DM).
Objective: We sought to examine the relationship between the Cutaneous Dermatomyositis Area (CDASI) and Severity Index, a DM-specific cutaneous severity instrument. and various QoL study instruments and to determine the impact of DM on QoL.
Methods: Skin-specific QoL instruments, the Skindex and the Dermatology Life Quality Index, and global medical QoL instruments, the Short Form 36 and the Health Assessment Questionnaire-Disability Index, were used. Pruritus was evaluated by a visual analog scale and a 0-to-10 scale in DM and cutaneous lupus erythematosus (CLE) populations, respectively.
Results: There was a significant correlation between the CDASI and all skin-specific QoL scores (lowest P = .0377). Using the Short Form 36, DM population was found to have significantly worse QoL scores than the general population with the exception of bodily pain (all subscore P values < .01). Furthermore, DM had a significantly lower vitality score, representing energy level, compared with CLE, hypertension, diabetes, and recent myocardial infarction scores (lowest P = .003). There was a significantly lower mental health score, representing overall mood, to all compared diseases except CLE and clinical depression (P values < .01 when significant). We found that DM produces more pruritus than CLE (P < .0001).
Limitations: A larger patient population needs to be studied to further assess QoL in patients with DM.
Conclusion: We conclude that DM has a large impact on QoL, even when compared with other diseases, and that DM skin disease activity correlates with a poorer QoL. (J Am Acad Dermatol 2011;65:1107-16.)

FRACTION; DIETARY FACTORS
AB Background: Laboratory and epidemiologic studies suggest that certain dietary supplements may alter risk of cutaneous squamous cell carcinoma (SCC).
Objective: We sought to examine the association between supplement use and SCC risk.
Methods: Cases (n = 415) were defined as Kaiser Permanente Northern California members with a pathology-verified SCC in 2004 and control subjects (n = 415) were age-, sex-, and race-matched members with no history of skin cancer. Supplement use and SCC risk factors were ascertained by questionnaire. Associations of SCC with use of multivitamins; vitamins A, C, D, and E; and grape seed extract were estimated as odds ratios and 95% confidence intervals using conditional logistic regression. Models were adjusted for SCC risk factors and other supplement use.
Results: Grape seed extract users had a significantly decreased risk of cutaneous SCC (adjusted odds ratio 0.26, confidence interval 0.08-0.89, P = .031). Multivitamin use was associated with a borderline significant reduction in SCC risk (adjusted odds ratio 0.71, confidence interval 0.51-1.00, P = .049). Use of vitamins A, C, 0, and E was not associated with SCC risk.
Limitations: The data may be prone to recall and selection bias because of the case-control design. No information was obtained on dose or duration of supplement use.
Conclusions: Use of grape seed extract may be associated with a decreased risk of cutaneous SCC. The other supplements included in our study did not reveal clear associations with SCC risk. (J Am Acad Dermatol 2011;65:1145-51.)

DT Article
ID VERTEBRAL COMPRESSION FRACTURES; POSTMENOPAUSAL WOMEN; RANDOMIZED-TRIAL;
SINGLE-CENTER; RISK; PAIN; VERTOS; EPIDEMIOLOGY
AB Purpose: To assess long-term clinical outcome of percutaneous vertebroplasty (PV).
Materials and Methods: PV was performed in 1,634 patients (1,387 women; median age 73 years +/- 9.3) with painful osteoporotic vertebral compression fractures (VCFs). All patients had back pain that persisted for >= 2 months with a concordant magnetic resonance imaging study. After PV, medical therapy for osteoporosis was continued, and patients were prospectively evaluated (follow-up 11.8-44.9 months, mean 25.0 months). Visual analog scale (VAS), Oswestry Disability Index (ODI), analgesic drug use, and use of external brace support were recorded at baseline and during follow-up. New occurrences of symptomatic vertebral fractures were recorded.
Results: The mean VAS score of 7.94 significantly improved to 1.12 at the primary endpoint (P < .001). Differences in patterns of analgesic usage compared with baseline values were highly statistically significant (marginal homogeneity test, P < .001). Median ODI values of 82% before treatment significantly decreased to 6% (P < .001). Before intervention, 1,279 patients wore a brace; 1,167 (91.2%) patients did not wear a brace after PV (chi(2) = 31.005, P < .0001). A new painful fracture with a significant higher proportion of contiguous vertebrae (63.6%) occurred in 214 (13.1%) patients (z = 7.59, P = .025).
Conclusions: PV can provide durable pain relief and improvement in ambulation in patients with VCFs.

AB The purpose was to explore whether there were any pathological characteristics of the end-stage osteoarthritic sclerotic lesion that have potential to participate in cartilage repair.
Specimens harvested following total knee surgery were examined for gross pathology including staining with Safranin O. Multiple small sections of the lesion were placed in tissue culture for 6 weeks. Gross examination and photographic documentation was made at 3 and 6 weeks. At 6 weeks the specimens from culture were subject to histological examination. The pathology of the end-stage osteoarthritic lesion showed sclerotic bone, dead osteons, hypervascularity and scattered cartilaginous aggregates. Additional observations showed multiple pitting on the sclerotic surface, which histologically was related to three events; fragmentation of dead bone, ruptured blood vessels, and eroded aggregates. There were no pathological or biological changes in the specimens following the time in tissue culture.
The in-depth pathological evaluation showed the end-stage osteoarthritic lesion to have certain features with potential to facilitate cartilage repair. The cartilaginous aggregates may be a participant in cartilage repair following surgery. The cartilaginous aggregates remained unchanged in the tissue culture absent the normal synovial joint chemical and physical environment and therefore further testing with a different experimental model would be necessary to establish these aggregates as a source of cartilage regeneration. The multiple small depressions in this lesion may have potential to be a "home" for therapeutics. (C) 2010 Elsevier B.V. All rights reserved.

AB Gene expression analysis can be a powerful tool in predicting patient outcomes and identifying patients who may benefit from targeted therapies. However, isolating human blood polymorphonuclear cells (PMNs) for genomic analysis has been challenging. We used a novel microfluidic technique that isolates PMNs by capturing CD66b(+) cells and compared it with dextran-Ficoll gradient isolation. We also used microfluidic isolation techniques for blood and bronchoalveolar lavage (BAL) samples of patients with acute respiratory distress syndrome (ARDS) to evaluate PMN genomic alterations secondary to pulmonary sequestration. PMNs obtained from ex vivo lipopolysaccharide (LPS)-stimulated or -unstimulated whole blood from five healthy volunteers were isolated by either dextran-Ficoll gradient, microfluidics capture, or a combination of the two techniques. Blood and BAL fluid PMNs were also isolated using microfluidics from seven hospitalized patients with ARDS. Gene expression was inferred from extracted RNA using Affymetrix U133 Plus 2.0 GeneChips. All methods of PMN isolation produced similar quantities of high-quality RNA, when adjusted for recovered cell number. Unsupervised analysis and hierarchical clustering indicated that LPS stimulation was the primary factor affecting gene expression patterns among all ex vivo samples. Patterns of gene expression from blood and BAL PMNs differed significantly from each other in the patients with ARDS. Isolation of PMNs by microfluidics can be applied to both blood and BAL specimens from critically ill, hospitalized patients. Unique genomic expression patterns are obtained from the blood and BAL fluid of critically ill patients with ARDS, and these differ significantly from genomic patterns seen after ex vivo LPS stimulation.

AB The success of potent antiretroviral treatment for HIV infection is primarily determined by adherence. We systematically review the evidence of effectiveness of interventions to increase adherence to antiretroviral treatment in sub-Saharan Africa. We identified 27 relevant reports from 26 studies of behavioural, cognitive, biological, structural, and combination interventions done between 2003 and 2010. Despite study diversity and limitations, evidence suggests that treatment supporters, directly observed therapy, mobile-phone text messages, diary cards, and food rations can effectively increase adherence in sub-Saharan Africa. However, some interventions are unlikely to have large or lasting effects, and others are effective only in specific settings. These findings emphasise the need for more research, particularly for randomised controlled trials, to examine the effect of context and specific features of intervention content on effectiveness. Future work should assess intervention targeting and selection of interventions based on behavioural theories relevant to sub-Saharan Africa.

AB The rapidly increasing use of pegasparaginase (pegASNase) in adults, after a half century of use of asparaginase (ASNase) in children, has prompted a need for guidelines in the management and prevention of toxicities of asparagine depletion in adults. Accordingly, an initial set of recommendations are provided herein. Major advantages of pegASNase are its 2-3-week duration of action, in contrast to less than 3 days with native ASNase, and the flexibility of intravenous or intramuscular administration of pegASNase and associated patient and physician convenience. The most frequent toxicities of both types of ASNase are hepatic and pancreatic, with pancreatitis being the most serious. Other toxicities are hypersensitivity reactions, thrombosis, nausea/vomiting, and fatigue. Whether or not the replacement of one dose of pegASNase for 6-9 doses of native ASNase can be achieved in adults with similar efficacy and acceptable toxicities to those achieved in children remains to be established.

Anti-tumor activity and pharmacokinetics were also evaluated. Eighteen patients (mean age 60.5 years; median 9 prior therapies) were enrolled. No dose-limiting toxicities (DLTs) were reported for IPI-504 doses up to 400 mg/m(2). The most common treatment-related adverse event was grade 1 infusion site pain (four patients). All other treatment-related events were assessed as grade 1 or 2 in severity. The area under the curve (AUC) increased with increasing dose, and the mean half-life was approximately 2-4 h for IPI-504 and its metabolites. Four patients had stable disease, demonstrating modest single-agent activity in relapsed or relapsed/refractory MM.

AB This study evaluated whether measures of psychological well-being, including coping style, are associated with advance care planning (ACP). Data were from the Hematology Communications Study (HEMA-COMM), a prospective observational study of physician-patient communication in patients with hematologic malignancies. ACP was defined as having a living will, having a health care proxy, discussing life support with family or friends and discussing life support with a doctor or nurse. A total of 293 patients participated: only 45 (15%) had all the elements of ACP; 215 (73%) had at least one element of ACP, while 33 (11%) did not engage in ACP. In multi-variate analysis, specific coping styles but not other measures of psychosocial well-being were associated with having written ACP. Verbal ACP was associated with patient-reported health and physician estimate of life expectancy. Our study suggests that tailoring ACP discussions to a patient's coping style may increase engagement in ACP.

AB Background: Pro- and antiinflammatory genes are expressed in epicardial adipose tissue (EAT). Our objectives were to characterize genes in EAT that may contribute specifically to coronary atherogenesis and to measure circulating adipokines matched to their messenger RNAs (mRNAs) in EAT. We hypothesized that severe coronary atherosclerosis (CAD) would preferentially affect gene expression in EAT as compared to substernal fat or subcutaneous thoracic adipose tissue (SAT), as well as circulating levels of adipokines.
Methods: Fat mRNA was quantified using reverse transcription polymerase chain reaction (RT-PCR), and circulating adipokines were measured by enzyme-linked immunosorbent assays (ELISAs) in patients with severe stable CAD and controls without severe CAD undergoing open heart surgery.
Results: A total of 39 of 70 mRNAs in EAT were significantly increased in CAD. Only 4 and 3 of these mRNAs were increased in substernal fat and SAT, respectively. Of the mRNAs increased in EAT, 17 were either inflammatory adipokines or proteins known to be involved in inflammatory processes, 7 were involved in oxidative stress and or oxygen species regulation, whereas 15 were proteins involved in metabolism and regulation of gene transcription or proteins unique to fat cells. The largest increases, over three-fold, were seen in GPX3, gp91 phox, p47phox, heme oxygenase, and interleukin-8 (IL-8). Tpl2 mRNA was uniquely elevated in all three fat depots from CAD patients, and its expression in SAT, but not in EAT or substernal fat, was directly correlated with homeostasis model assessment of insulin resistance (HOMA-IR) values. Compared to controls, there were no associations between circulating levels of IL-8, lipocalin-2, nerve growth factor (NGF), RANTES, CD-163, GPX-3, monocyte chemotactic protein-1 (MCP-1)/CCL2, leptin, soluble vascular endothelial growth factor receptor-1 (sFLT1), fatty acid binding protein-4 (FABP-4), and plasminogen activator inhibitor-1 (PAI-1) and increases in their gene expression in EAT adjacent to CAD.
Conclusions: Expression of proinflammatory, redox, endothelial cell, and angiogenic genes in EAT is depot specific and supports the hypothesis that pathophysiologically EAT contributes locally to CAD. CAD links with these fat depots might involve Tpl2 as a primary response indicator.

AB Background: Elevated insulin resistance (IR), triglycerides (TG), body mass index (BMI), and waist circumference (WC) are features of the metabolic syndrome. Although several single- nucleotide polymorphisms (SNPs) associated with these traits have been reported, no study has reported their risk allele frequencies and effect sizes among the major U.S. race/ethnic groups in a nationally representative sample.
Methods: We compared the risk allele frequencies of eight SNPs previously associated with IR, TG, BMI, or WC by race/ethnicity (non-Hispanic white, non-Hispanic black, Mexican American) in 3,030 participants of the National Health and Nutrition Examination Study III (NHANES III). In regression models predicting IR, TG, BMI, WC, and metabolic syndrome, we tested whether the SNP effect sizes on these traits varied by race/ ethnicity.
Results: Risk allele frequencies varied by race/ethnicity for all eight loci (P < 0.0001). The directionality of effects of the variants on IR, TG, WC, and BMI was generally consistent with previous observations and did not differ by race/ethnicity (P > 0.001), although our study had low power for this test. No SNP predicted metabolic syndrome in any of the three groups (P > 0.05).
Conclusions: The significance of racial/ethnic differences in risk allele frequencies merits consideration if genetic discoveries are to have clinical and public health applicability.

AB Leptin and adiponectin are hormones secreted from adipocytes that have important roles in metabolism and energy homeostasis. This review evaluates the effects of leptin and adiponectin on beta-cell function by analyzing and compiling results from human clinical trials and epidemiologic studies as well as in vitro and in vivo experiments. Leptin has been shown to inhibit ectopic fat accumulation and thereby prevent beta-cell dysfunction and protect the beta-cell from cytokine- and fatty acid-induced apoptosis. However, leptin suppresses insulin gene expression and secretion as well as glucose transport into the beta-cell. Adiponectin stimulates insulin secretion by enhancing exocytosis of insulin granules and upregulating the expression of the insulin gene; however, this effect depends on the prevailing glucose concentration and status of insulin resistance. In addition, adiponectin has antiapoptotic properties in beta-cells. Available evidence concerning the role of these adipokines on insulin secretion, insulin gene expression, and apoptosis is not always entirely consistent; and many fundamental questions remain to be answered by future studies.

AB Opiate addiction is associated with many adverse health and social harms, fatal overdose, infectious disease transmission, elevated health care costs, public disorder, and crime. Although community-based addiction treatment programs continue to reduce the harms of opiate addiction with narcotic substitution therapy such as methadone maintenance, there remains a need to find a substance that not only blocks opiate-type receptors (mu, delta, etc.) but also provides agonistic activity; hence, the impetus arose for the development of a combination of narcotic antagonism and mu receptor agonist therapy. After three decades of extensive research, the federal Drug Abuse Treatment Act 2000 (DATA) opened a window of opportunity for patients with addiction disorders by providing increased access to options for treatment. DATA allows physicians who complete a brief specialty-training course to become certified to prescribe buprenorphine and buprenorphine/naloxone (Subutex, Suboxone) for treatment of patients with opioid dependence. Clinical studies indicate that buprenorphine maintenance is as effective as methadone maintenance in retaining patients in substance abuse treatment and in reducing illicit opioid use. With that stated, we must consider the long-term benefits or potential toxicity attributed to Subutex or Suboxone. We describe a mechanism whereby chronic blockade of opiate receptors, in spite of only partial opiate agonist action, may ultimately block dopaminergic activity causing anti-reward and relapse potential. While the direct comparison is not as yet available, toxicity to buprenorphine can be found in the scientific literature. In considering our cautionary note in this commentary, we are cognizant that, to date, this is what we have available, and until such a time when the real magic bullet is discovered, we will have to endure. However, more than anything else this commentary should at least encourage the development of thoughtful new strategies to target the specific brain regions responsible for relapse prevention.

AB The prevalence of spontaneous mutations increases with age in the male germline; consequently, older men have an increased risk of siring children with genetic disease due to de novo mutations. The lacI transgenic mouse can be used to study paternal age effects, and in this system, the prevalence of de novo mutations increases in the male germline at old ages. Mutagenesis is linked with DNA repair capacity, and base excision repair (BER), which can ameliorate spontaneous DNA damage, decreases in nuclear extracts of spermatogenic cells from old mice. Mice heterozygous for a null allele of the Apex1 gene, which encodes apurinic/apyrimidinic endonuclease I (APEN), an essential BER enzyme, display an accelerated increase in spontaneous germline mutagenesis early in life. Here, the consequences of lifelong reduction of APEN on genetic instability in the male germline were examined, for the first time, at middle and old ages. Mutant frequency increased earlier in spermatogenic cells from Apex1(+/-) mice (by 6 months of age). Nuclear DNA damage increased with age in the spermatogenic lineage for both wild-type and Apex1(+/-) mice. By old age, mutant frequencies were similar for wild-type and APEN-deficient mice. Mitochondrial genome-repair also depends on APEN, and novel analysis of mitochondrial-DNA(mtDNA) damage revealed an increase in the Apex1(+/-) spermatogenic cells by middle age. Thus, Apex1 heterozygosity results in accelerated damage to mtDNA and spontaneous mutagenesis, consistent with an essential role for APEN in maintaining nuclear and mtDNA integrity in spermatogenic cells throughout life.

AB Biopsies from a typical case of pseudotumor following metal-on-metal hip resurfacing (MoMHR) were analyzed using light and transmission electron microscopy, backscatter scanning electron microscopy and energy dispersive x-ray spectrometry (EDS). Heavy macrophage infiltration was observed in all black pigmented specimens. Metal nanoparticles (NPs) were observed exclusively within phagosomes of living macrophages and fragments of dead macrophages. Although dead fibroblasts were found to be juxtaposed with dead and disintegrated macrophages, the NPs were not seen within either live or dead fibroblasts. Chromium (Cr) but not cobalt (Co) was the predominant component of the remaining wear NPs in tissue. The current study finding suggests that corrosion of Co in phagosomes of macrophages and resultant Co ion release lead to tissue necrosis and adverse soft tissue reactions (pseudotumors). Further studies are required to elucidate the precise mechanism of intracellular corrosion of metal NPs and the long-term toxicity of the Cr remaining in the peri-prosthetic tissues.
From the Clinical Editor: In this study of metal-on-metal hip resurfacing-related tissue necrosis and pseudotumor formation, corrosion and decomposition of metallic cobalt in phagosomes of macrophages and resultant cobalt ion release were demonstrated to be the key elements of pathogenesis.

AB Functionalized fullerenes represent a new class of photosensitizer (PS) that is being investigated for photodynamic therapy (PDT) of various diseases, including cancer. We tested the hypothesis that fullerenes could be used to mediate PDT of intraperitoneal (IP) carcinomatosis in a mouse model. In humans this form of cancer responds poorly to standard treatment and manifests as a thin covering of tumor nodules on intestines and on other abdominal organs. We used a colon adenocarcinoma cell line (CT26) stably expressing luciferase to allow monitoring of IP tumor burden in BALB/c mice by noninvasive real-time optical imaging using a sensitive low-light camera. IP injection of a preparation of N-methylpyrrolidinium-fullerene formulated in Cremophor-EL micelles, followed by white-light illumination delivered through the peritoneal wall (after creation of a skin flap), produced a statistically significant reduction in bioluminescence and a survival advantage in mice.
From the Clinical Editor: This team of investigators report on functionalized fullerenes, to be used as photosensitizer for photodynamic therapy and demonstrate the efficacy of this method in an intraperitoneal carcinomatosis mouse model. (C) 2011 Elsevier Inc. All rights reserved.

AB So far, two genes associated with familial melanoma have been identified, accounting for a minority of genetic risk in families. Mutations in CDKN2A account for approximately 40% of familial cases(1), and predisposing mutations in CDK4 have been reported in a very small number of melanoma kindreds(2). Here we report the whole-genome sequencing of probands from several melanoma families, which we performed in order to identify other genes associated with familial melanoma. We identify one individual carrying a novel germline variant (coding DNA sequence c. G1075A; protein sequence p. E318K; rs149617956) in the melanoma-lineage-specific oncogene microphthalmia-associated transcription factor (MITF). Although the variant co-segregated with melanoma in some but not all cases in the family, linkage analysis of 31 families subsequently identified to carry the variant generated a log of odds (lod) score of 2.7 under a dominant model, indicating E318K as a possible intermediate risk variant. Consistent with this, the E318K variant was significantly associated with melanoma in a large Australian case-control sample. Likewise, it was similarly associated in an independent case-control sample from the United Kingdom. In the Australian sample, the variant allele was significantly over-represented in cases with a family history of melanoma, multiple primary melanomas, or both. The variant allele was also associated with increased naevus count and non-blue eye colour. Functional analysis of E318K showed that MITF encoded by the variant allele had impaired sumoylation and differentially regulated several MITF targets. These data indicate that MITF is a melanoma-predisposition gene and highlight the utility of whole-genome sequencing to identify novel rare variants associated with disease susceptibility.

AB Selective autophagy involves the recognition and targeting of specific cargo, such as damaged organelles, misfolded proteins, or invading pathogens for lysosomal destruction(1-4). Yeast genetic screens have identified proteins required for different forms of selective autophagy, including cytoplasm-to-vacuole targeting, pexophagy and mitophagy, and mammalian genetic screens have identified proteins required for autophagy regulation(5). However, there have been no systematic approaches to identify molecular determinants of selective autophagy in mammalian cells. Here, to identify mammalian genes required for selective autophagy, we performed a high-content, image-based, genome-wide small interfering RNA screen to detect genes required for the colocalization of Sindbis virus capsid protein with autophagolysosomes. We identified 141 candidate genes required for viral autophagy, which were enriched for cellular pathways related to messenger RNA processing, interferon signalling, vesicle trafficking, cytoskeletal motor function and metabolism. Ninety-six of these genes were also required for Parkin-mediated mitophagy, indicating that common molecular determinants may be involved in autophagic targeting of viral nucleocapsids and autophagic targeting of damaged mitochondria. Murine embryonic fibroblasts lacking one of these gene products, the C2-domain containing protein, SMURF1, are deficient in the autophagosomal targeting of Sindbis and herpes simplex viruses and in the clearance of damaged mitochondria. Moreover, SMURF1-deficient mice accumulate damaged mitochondria in the heart, brain and liver. Thus, our study identifies candidate determinants of selective autophagy, and defines SMURF1 as a newly recognized mediator of both viral autophagy and mitophagy.

AB Amyotrophic lateral sclerosis (ALS) is characterized by upper and lower motor neuron dysfunction and loss, rapidly progressive muscle weakness, wasting and death(1-3). Many factors, including mitochondrial dysfunction, may contribute to ALS pathogenesis(4-9). Riluzole, which has shown only modest benefits in a measure of survival time without demonstrated effects on muscle strength or function, is the only approved treatment for ALS(10,11). We tested the putative mitochondrial modulator dexpramipexole (KNS-760704; (6R)-4,5,6,7-tetrahydro-N6-propyl-2,6-benzothiazole-diamine)(12-14) in subjects with ALS in a two-part, double-blind safety and tolerability study, with a preliminary assessment of its effects on functional decline and mortality. In part 1, the effects of dexpramipexole (50, 150 or 300 mg d(-1)) versus placebo were assessed over 12 weeks. In part 2, after a 4-week, single-blind placebo washout, continuing subjects were re-randomized to dexpramipexole at 50 mg d(-1) or 300 mg d(-1) as double-blind active treatment for 24 weeks. Dexpramipexole was safe and well tolerated. Trends showing a dose-dependent attenuation of the slope of decline of the ALS Functional Rating Scale-Revised (ALSFRS-R) in part 1 and a statistically significant (P = 0.046) difference between groups in a joint rank test of change from baseline in ALSFRS-R and mortality in part 2 strongly support further testing of dexpramipexole in ALS.

AB Advancing understanding of human coronary artery disease requires new methods that can be used in patients for studying atherosclerotic plaque microstructure in relation to the molecular mechanisms that underlie its initiation, progression and clinical complications, including myocardial infarction and sudden cardiac death. Here we report a dual-modality intra-arterial catheter for simultaneous microstructural and molecular imaging in vivo using a combination of optical frequency domain imaging (OFDI) and near-infrared fluorescence (NIRF) imaging. By providing simultaneous molecular information in the context of the surrounding tissue microstructure, this new catheter could provide new opportunities for investigating coronary atherosclerosis and stent healing and for identifying high-risk biological and structural coronary arterial plaques in vivo.

AB Gastrointestinal stromal tumours (GISTs) are a paradigm for the development of personalized treatment for cancer patients. The nearly simultaneous discovery of a biomarker that is reflective of their origin and the presence of gain-of-function kinase mutations in these tumours set the stage for more accurate diagnosis and the development of kinase inhibitor therapy. Subsequent studies of genotype and phenotype have led to a molecular classification of GIST and to treatment optimization on the basis of molecular subtype. The study of drug-resistant tumours has advanced our understanding of kinase biology, enabling the development of novel kinase inhibitors. Further improvements in GIST treatment may require targeting GIST stem cell populations and/or additional genomic events.

AB The increasing incidence of obesity and its co-morbid conditions poses a great challenge to global health. In addition to cardiovascular disease and diabetes, epidemiological data demonstrate a link between obesity and multiple types of cancer. The molecular mechanisms underlying how obesity causes an increased risk of cancer are poorly understood. Obesity disrupts the dynamic role of the adipocyte in energy homeostasis, resulting in inflammation and alteration of adipokine (for example, leptin and adiponectin) signalling. Additionally, obesity causes secondary changes that are related to insulin signalling and lipid deregulation that may also foster cancer development. Understanding these molecular links may provide an avenue for preventive and therapeutic strategies to reduce cancer risk and mortality in an increasingly obese population.

AB The discovery of X-chromosome inactivation (XCI) celebrated its golden anniversary this year. Originally offered as an explanation for the establishment of genetic equality between males and females, 50 years on, XCI presents more than a curious gender-based phenomenon that causes silencing of sex chromosomes. How have the mysteries of XCI unfolded? And what general lessons can be extracted? Several of the cell biological mechanisms that are used to establish the inactive X chromosome, including regulatory networks of non-coding RNAs and unusual nuclear dynamics, are now suspected to hold true for processes occurring on a genome-wide scale.

AB Incidental vertebral lesions on imaging of the spine are commonly encountered in clinical practice. Contributing factors include the aging population, the increasing prevalence of back pain, and increased usage of MR imaging. Additionally, refinements in CT and MR imaging have increased the number of demonstrable lesions. The management of incidental findings varies among practitioners and commonly depends more on practice style than on data or guidelines. In this article we review incidental findings within the vertebral column and review management of these lesions, based on available Class III data. (DOI: 10.3171/2011.9.FOCUS11207)

AB The regulation of energy intake is a complex process involving the integration of homeostatic signals and both internal and external sensory inputs. To better understand the neurobiology of this process and how it may be dysfunctional in obesity, this study examined activity of the brain's "default network" in reduced-obese (RO) as compared to lean individuals. The default network is a group of functionally connected brain regions thought to play an important role in internally directed cognitive activity and the interplay between external and internal sensory processing. Functional magnetic resonance imaging was performed in 24 lean and 18 RO individuals in the fasted state after 2 days of eucaloric energy intake and after 2 days of 30% overfeeding in a counterbalanced design. Scanning was performed while subjects passively viewed images of food and nonfood objects. Independent component analysis was used to identify the default network component. In the eucaloric state, greater default network activity was observed in RO compared to lean individuals in the lateral inferior parietal and posterior cingulate cortices. Activity was positively correlated with appetite. Overfeeding resulted in increased default network activity in lean but not RO individuals. These findings suggest that the function of the default network, a major contributor to intrinsic neuronal activity, is altered in obesity and/or obese-prone individuals. Future studies of the network's function and its relationship to other brain networks may improve our understanding of the mechanisms and treatment of obesity.

AB The metabolic requirements of cancer cells differ from that of their normal counterparts. To support their proliferation, cancer cells switch to a fermentative metabolism that is thought to support biomass production. Instances where metabolic enzymes promote tumorigenesis remain rare. However, an enzyme involved in the de novo synthesis of serine, 3-phosphoglycerate dehydrogenase (PHGDH), was recently identified as a putative oncogene. The potential mechanisms by which PHGDH promotes cancer are discussed.

AB Yang, H., Magpayo, N., Rusek, A., Chiang, I-H., Sivertz, M. and Held, K. D. Effects of Very Low Fluences of High-Energy Protons or Iron Ions on Irradiated and Bystander Cells. Radiat. Res. 176, 695-705 (2011).
In space, astronauts are exposed to radiation fields consisting of energetic protons and high atomic number, high-energy (HZE) particles at very low dose rates or fluences. Under these conditions, it is likely that, in addition to cells in an astronaut's body being traversed by ionizing radiation particles, unirradiated cells can also receive intercellular bystander signals from irradiated cells. Thus this study was designed to determine the dependence of DNA damage induction on dose at very low fluences of charged particles. Novel techniques to quantify particle fluence have been developed at the NASA Space Radiation Biology Laboratory (NSRL) at Brookhaven National Laboratory (BNL). The approach uses a large ionization chamber to visualize the radiation beam coupled with a scintillation counter to measure fluence. This development has allowed us to irradiate cells with 1 GeV/nucleon protons and iron ions at particle fluences as low as 200 particles/cm(2) and quantify biological responses. Our results show an increased fraction of cells with DNA damage in both the irradiated population and bystander cells sharing medium with irradiated cells after low fluences. The fraction of cells with damage, manifest as micronucleus formation and 53BP1 focus induction, is about 2-fold higher than background at doses as low as similar to 0.47 mGy iron ions (similar to 0.02 iron ions/cell) or similar to 70 mu Gy protons (similar to 2 protons/cell). In the irradiated population, irrespective of radiation type, the fraction of damaged cells is constant from the lowest damaging fluence to about 1 cGy, above which the fraction of damaged cells increases with dose. In the bystander population, the level of damage is the same as in the irradiated population up to 1 cGy, but it does not increase above that plateau level with increasing dose. The data suggest that at fluences of high-energy protons or iron ions less than about 5 cGy, the response in irradiated cell populations may be dominated by the bystander response.

The Small Animal Radiation Research Platform (SARRP) is a novel isocentric irradiation system that enables state-of-the-art image-guided radiotherapy research to be performed with animal models. This paper reports the results obtained from investigations assessing the radiation dose delivered by the SARRP to different anatomical target volumes in mice. Surgically implanted metal oxide semiconductor field effect transistors (MOSFET) dosimeters were employed for the dose assessment. The results reveal differences between the calculated and measured dose of -3.5 to 0.5%, -5.2 to -0.7%, -3.9 to 0.5%, -5.9 to 2.5%, -5.5 to 0.5%, and -4.3 to 0% for the left kidney, liver, pancreas, prostate, left lung, and brain, respectively. Overall, the findings show less than 6% difference between the delivered and calculated dose, without tissue heterogeneity corrections. These results provide a useful assessment of the need for tissue heterogeneity corrections in SARRP dose calculations for clinically relevant tumor model sites. (C) 2011 by Radiation Research Society

AB Fopx3(+) Treg safeguard against autoimmune diseases and immune pathology. The extrathymic conversion of naive T cells into Foxp3(+) regulatory T cells can be achieved in vivo by the delivery of strong-agonist ligands under subimmunogenic conditions. Tolerogenic vaccination with strong-agonist mimetopes of self-antigen to promote self-antigen specific tolerance may represent the most specific and safest means of preventing autoimmunity. This review discusses the requirements for induction of dominant tolerance exerted by Foxp3(+) Tregs in autoimmunity with special emphasis on their impact to interfere with T1D. The future goals are the understanding of self-non-self discrimination at the cellular and molecular level, which should then enable investigators to develop clinical vaccination protocols that specifically interfere with unwanted immune responses.

AB Mounting an efficient immune response to pathogens while avoiding damage to host tissues is the central task of the immune system. Emerging evidence has highlighted the contribution of the CD8(+) lineage of regulatory T cells to the maintenance of self-tolerance. Specific recognition of the MHC class Ib molecule Qa-1 complexed to peptides expressed by activated CD4(+) T cells by regulatory CD8(+) T cells triggers an inhibitory interaction that prevents autoimmune responses. Conversely, defective Qa-1-restricted CD8(+). regulatory activity can result in development of systemic autoimmune disease. Here, we review recent research into the cellular and molecular basis of these regulatory T cells, their mechanism of suppressive activity and the potential application of these insights into new treatments for autoimmune disease and cancer.

AB Study Objective: To evaluate the association between self-reported sleep quality among older adults during inpatient post-acute rehabilitation and one-year survival.
Design: Prospective, observational cohort study.
Setting: Two inpatient post-acute rehabilitation sites (one community and one Veterans Administration).
Participants: Older patients (aged >= 65 years, n = 245) admitted for inpatient post-acute rehabilitation.
Interventions: None.
Measurements and Results: Within one year of post-acute rehabilitation, 57 participants (23%) were deceased. Cox proportional hazards models showed that worse Pittsburgh Sleep Quality Index (PSQI) total scores during the post-acute care stay were associated with increased mortality risk when controlling for amount of rehabilitation therapy received, comorbidities, and cognitive functioning (Hazard ratio [95% CI] = 1.11 [1.02-1.20]). Actigraphically estimated sleep was unrelated to mortality risk.
Conclusions: Poorer self-reported sleep quality, but not objectively estimated sleep parameters, during post-acute rehabilitation was associated with shorter survival among older adults. This suggests self-reported poor sleep may be an important and potentially modifiable risk factor for negative outcomes in these vulnerable older adults. Studies of interventions to improve sleep quality during inpatient rehabilitation should therefore be undertaken, and the long-term health benefits of improved sleep should be explored.

AB Objective: Telemedicine is increasingly being used to provide consultation for healthcare in rural areas. Little work has been done with dementia although preliminary research suggests that clinical diagnosis performed via telemedicine consultation is valid. We implemented a program to provide multidisciplinary, state-of-the-art diagnosis of cognitive impairment by video-telemedicine (VTM) integrated into a clinical setting. Methods: Patients at a rural veteran's community clinic were referred by their local provider for evaluation of memory complaints by the multidisciplinary team of the San Francisco Veterans Administration (SFVA) Memory Disorders Clinic (MDC). The evaluation was integrated into the usual clinic structure and included a neurological evaluation and neuropsychological testing by the MDC team via video assisted by a remote clinician at the community clinic. Results: We evaluated 15 new patients referred to our multidisciplinary clinic. In each case, the VTM format permitted the MDC team to arrive at a working diagnosis; 12 patients with dementia, two with mild cognitive impairment, and one cognitively normal. Relevant treatment recommendations were made to the patients and caregivers. The evaluation results were discussed with providers who joined the MDC postclinic conference via VTM. In the majority of cases, recommendations were followed and there was satisfaction with VTM by providers and patients. Conclusions: VTM is emerging as an effective way to provide consultation and care to rural residents who may not have access to specialty services and can be integrated into current clinical settings.

Paired pre- and post-photodynamic therapy biopsy samples from the same anatomical levels of 20 individuals who had undergone photodynamic therapy for Barrett's esophagus with high-grade dysplasia and/or intramucosal carcinoma were immunostained using a cyclooxygenase-2 monoclonal antibody. Cyclooxygenase-2 expression was graded in squamous epithelium, Barrett's esophagus, and neoplasia (if present) as follows: grade 0 (no staining), grade 1 (staining in 1-10% of cells), grade 2 (staining in 11-90% of cells), and grade 3 (staining in > 90% of cells). Pre-photodynamic therapy median cyclooxygenase-2 expression was grade 2 (range 1-3) in neoplastic foci and grade 1 (range 1-3) in nondysplastic Barrett's esophagus (P = 0.0009 for pairwise comparison). With the exception of a few cells staining in the basal epithelial layers, median cyclooxygenase-2 expression was graded as 0 (similar to controls) in both pre-photodynamic therapy squamous epithelium and post-photodynamic therapy neosquamous epithelium. This was significantly lower when compared to either neoplastic foci (P < 0.0001) or nondysplastic Barrett's esophagus (P < 0.0001) pre-photodynamic therapy. Notably, in four patients with post-photodynamic therapy recurrent neoplasia, cyclooxygenase-2 expression returned to elevated levels. Cyclooxygenase-2 expression is elevated in Barrett's esophagus with high-grade dysplasia or intramucosal carcinoma prior to photodynamic therapy. Following successful photodynamic therapy, cyclooxygenase-2 expression in neosquamous epithelium returns to a low baseline level similar to that observed in native esophageal squamous epithelium. Post-photodynamic therapy neoplastic recurrence is associated with elevated cyclooxygenase-2 expression. Prospective studies should determine whether cyclooxygenase inhibitors have a role as adjuvant therapy to prevent recurrence of Barrett's esophagus following endoscopic therapy.

AB Background: Chronic misuse of alcohol results in widespread damage to the brain. Prior morphometric studies have examined cortical atrophy in individuals with alcoholism; however, no previous studies have examined alcohol-associated atrophy using cortical thickness measurements to obtain regional mapping of tissue loss across the full cortical surface.
Methods: We compared cortical thickness measures from 31 abstinent individuals with a history of prior alcohol abuse to 34 healthy nonalcoholic control participants (total sample size = 65). Cortical surface models were created from high-resolution T1-weighted images, and cortical thickness was then estimated as the distance between the gray matter / white matter boundary and the outer cortical surface.
Results: Abstinent alcoholics showed reduced whole-brain thickness as compared to nonalcoholic participants. Decreases in thickness were found bilaterally in (i) superior frontal, (ii) precentral, (iii) postcentral, (iv) middle frontal, (v) middle / superior temporal, (vi) middle temporal, and (vii) lateral occipital cortical regions. Decreased cortical thickness in the alcoholic group was associated with severity of alcohol abuse.
Conclusions: These findings demonstrate widespread reduction in cortical thickness as a consequence of chronic alcoholism, with most severe reductions in frontal and temporal brain regions.

AB The treatment of HIV infection has dramatically reduced the incidence of AIDS-related illnesses. At the same time, non-AIDS-related illnesses such as cardiovascular and bone disease are becoming more prevalent in this population. The mechanisms of these illnesses are complex and are related in part to the HIV virus, antiretroviral medications prescribed for HIV infection, traditional risk factors exacerbated by HIV, and lifestyle and nutritional factors. Further prospective research is needed to clarify the mechanisms by which HIV, antiretroviral medications, and nutritional abnormalities contribute to bone and cardiovascular disease in the HIV population. Increasingly, it is being recognized that optimizing the treatment of HIV infection to improve immune function and reduce viral load may also benefit the development of non-AIDS-related illnesses such as cardiovascular and bone disease.

AB Food insecurity, which affects >1 billion people worldwide, is inextricably linked to the HIVepidemic. We present a conceptual framework of the multiple pathways through which food insecurity and HIV/AIDS may be linked at the community, household, and individual levels. Whereas the mechanisms through which HIV/AIDS can cause food insecurity have been fairly well elucidated, the ways in which food insecurity can lead to HIV are less well understood. We argue that there are nutritional, mental health, and behavioral pathways through which food insecurity leads to HIV acquisition and disease progression. Specifically, food insecurity can lead to macronutrient and micronutrient deficiencies, which can affect both vertical and horizontal transmission of HIV, and can also contribute to immunologic decline and increased morbidity and mortality among those already infected. Food insecurity can have mental health consequences, such as depression and increased drug abuse, which, in turn, contribute to HIV transmission risk and incomplete HIV viral load suppression, increased probability of AIDS-defining illness, and AIDS-related mortality among HIV-infected individuals. As a result of the inability to procure food in socially or personally acceptable ways, food insecurity also contributes to risky sexual practices and enhanced HIV transmission, as well as to antiretroviral therapy nonadherence, treatment interruptions, and missed clinic visits, which are strong determinants of worse HIV health outcomes. More research on the relative importance of each of these pathways is warranted because effective interventions to reduce food insecurity and HIV depend on a rigorous understanding of these multifaceted relationships.

AB BACKGROUND: Although processes of care are common proxies for health care quality, their associations with medical outcomes remain uncertain.
METHODS: For 2076 patients hospitalized with pneumonia from 32 emergency departments, we used multilevel logistic regression modeling to assess independent associations between patient outcomes and the performance of 4 individual processes of care (assessment of oxygenation, blood cultures, and rapid initiation [<4 hours] and appropriate selection of antibiotic therapy) and the cumulative number of processes of care performed.
RESULTS: Overall, 141 patients (6.8%) died. Mortality was 0.3% to 1.7% lower for patients who had each of the individual processes of care performed (P >= .13 for each comparison); mortality was 7.5% for patients who had 0 to 2 processes of care, 7.2% for those with 3 processes of care, and 5.8% for those with all 4 processes of care performed (P = .39). Mortality was not significantly associated with either individual or cumulative process measures in multivariable models.
CONCLUSION: Neither the individual processes of care nor the cumulative number performed is associated with short-term mortality for pneumonia. Published by Elsevier Inc. The American Journal of Medicine (2011) 124, 1175.e9-1175.e17

AB OBJECTIVE: We sought to examine the evolution of surgical care for early-stage endometrial cancers and factors affecting use of laparoscopy.
STUDY DESIGN: Women with surgically managed early-stage endometrial cancer were divided into 2 groups corresponding to before and after addition of faculty with formal fellowship training in laparoscopic staging and access to a robotic surgery platform.
RESULTS: In all, 502 women were identified. Laparoscopic management increased from 24-69% between time periods (P < .0001). Performance of comprehensive surgical staging, and lymph node counts, increased (P < .0001) despite an increase in median body mass index (P = .001). A traditional "straight stick" technique was performed in 72% of laparoscopic cases during the later period. Laparoscopy patients had lower estimated blood losses and shorter hospital stays (each P < .0001) compared to laparotomy patients.
CONCLUSION: Addition of faculty with formal fellowship training in laparoscopic staging and access to a robotic surgery platform shifted management of early-stage endometrial cancer toward laparoscopy.

AB OBJECTIVE. Though classically thought of as an osseous-based sarcoma of children and adolescents, it is important to recognize that approximately 20% of all cases of Ewing sarcoma family of tumors (ESFT) occur in patients older than 18 years, often with extraskeletal disease. Understanding the specific imaging features, manners of presentation, and patterns of behavior of ESFT is therefore important in all settings.
CONCLUSION. This article presents the imaging findings of ESFT in the adult, with specific attention to extraskeletal manifestations.

AB OBJECTIVE. The purpose of this article is to present the important malignancies associated with the most common hereditary cancer syndromes.
CONCLUSION. Hereditary cancer syndromes comprise 5% of all cancers and have an increased risk of early onset and of multiple or bilateral malignancies. Radiologists should be familiar with various hereditary cancer syndromes and their common associations because early detection of these neoplasms may help decrease patient morbidity and mortality.

AB OBJECTIVE. The purpose of this article is to illustrate the common locations of desmoid tumors (deep fibromatosis), complications of intra-and extraabdominal desmoids, and treatment-related changes in their imaging appearance.
CONCLUSION. Desmoids are locally aggressive fibrous tumors with a tendency to recur. Desmoids can be intraabdominal, in the abdominal wall, or extraabdominal. Complications, such as compression or invasion of adjacent structures, and abscess formation can occur. Treatment options include observation, local treatment (surgery, radiotherapy), or systemic therapy (conventional chemotherapy, molecular targeted agents).

TI 2-Deoxy-D-Glucose Attenuates Isoflurane-Induced Cytotoxicity in an In

APOPTOSIS; OXIDATIVE STRESS; TRANSGENIC MICE; BETA-PEPTIDE; ANESTHESIA;
EXPOSURE; NEUROTOXICITY
AB BACKGROUND: beta-Amyloid protein (A beta) accumulation and caspase activation have been shown to contribute to Alzheimer disease neuropathogenesis. A beta is produced from amyloid precursor protein through proteolytic processing by aspartyl protease beta-site amyloid precursor protein-cleaving enzyme (BACE). The inhaled anesthetic isoflurane has been shown to induce caspase activation and increase levels of BACE and A beta. However, the underlying mechanisms and interventions of the isoflurane-induced neurotoxicity remain largely to be determined. The glucose analog 2-deoxy-D-glucose (2-DG) has neuroprotective effects. Therefore, we sought to determine whether 2-DG can reduce caspase-3 activation and the increase in the levels of BACE and reactive oxygen species (ROS) induced by isoflurane.
METHODS: H4 human neuroglioma cells were treated with saline or 2-DG (5 mM) for 1 hour followed by a control condition or 2% isoflurane for 6 hours. The levels of caspase-3 cleavage (activation), BACE, cytosolic calcium, and ROS were determined. Two-way analysis of variance was used to assess the interactions of 2-DG and isoflurane on caspase-3 activation, and levels of BACE and ROS.
RESULTS: In H4 human neuroglioma cells, 2-DG reduced the caspase-3 activation (477% vs 186%, F = 8.68; P = 0.019) and the increase in BACE levels (345% vs 123%, F = 42.24; P = 0.0002) induced by isoflurane. 2-DG decreased the levels of cytosolic calcium and ROS (100% vs 66%, F = 1.94; P = 0.014).
CONCLUSIONS: These results suggest that 2-DG may decrease oxidative stress and increase cytosolic calcium levels, thus attenuating isoflurane-induced neurotoxicity. (Anesth Analg 2011;113:1468-75)

AB Background: Progression-free survival (PFS) was significantly longer for the lapatinib plus trastuzumab (L+T) arm than for L alone in a phase III, randomized, open-label study of women with human epidermal growth factor receptor 2 positive metastatic breast cancer who had documented progression on at least one T-containing regimen in the metastatic setting. This analysis focused on impact of treatments on health-related quality of life (HRQOL).
Methods: HRQOL was assessed using the Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire. Changes from baseline and time to deterioration were analyzed in the intent-to-treat population.
Results: Differences between the treatment arms in adjusted mean change from baseline favored the L+T arm, ranging from 0.0 to 4.1 (FACT-B), 1.0-4.0 [Functional Assessment of Cancer Therapy-General (FACT-G)], and 0.5-2.7 (Trial Outcome Index). Most differences were not statistically significant, except for FACT-G at week 12 (delta = 4.0, P = 0.037). Similar results were found in a sensitivity analysis that included HRQOL records up to patient withdrawal from original randomized treatment. The longer time to HRQOL deterioration in the L+T arm was not statistically significant (FACT-B hazard ratio, 0.82; 95% confidence interval 0.56-1.20).
Conclusion: The addition of lapatinib to trastuzumab prolonged PFS while improving or maintaining near-term HRQOL, suggesting a meaningful clinical benefit to patients.

AB Background: Personalizing non-small-cell lung cancer (NSCLC) therapy toward oncogene addicted pathway inhibition is effective. Hence, the ability to determine a more comprehensive genotype for each case is becoming essential to optimal cancer care.
Methods: We developed a multiplexed PCR-based assay (SNaPshot) to simultaneously identify > 50 mutations in several key NSCLC genes. SNaPshot and FISH for ALK translocations were integrated into routine practice as Clinical Laboratory Improvement Amendments-certified tests. Here, we present analyses of the first 589 patients referred for genotyping.
Results: Pathologic prescreening identified 552 (95%) tumors with sufficient tissue for SNaPshot; 51% had >= 1 mutation identified, most commonly in KRAS (24%), EGFR (13%), PIK3CA (4%) and translocations involving ALK (5%). Unanticipated mutations were observed at lower frequencies in IDH and beta-catenin. We observed several associations between genotypes and clinical characteristics, including increased PIK3CA mutations in squamous cell cancers. Genotyping distinguished multiple primary cancers from metastatic disease and steered 78 (22%) of the 353 patients with advanced disease toward a genotype-directed targeted therapy.
Conclusions: Broad genotyping can be efficiently incorporated into an NSCLC clinic and has great utility in influencing treatment decisions and directing patients toward relevant clinical trials. As more targeted therapies are developed, such multiplexed molecular testing will become a standard part of practice.

TI A Most Unusual Patient at the Massachusetts General Hospital
SO ANNALS OF SURGERY
LA English
DT Article
ID CARMINE
AB This year marks 200 years of patient care at the Massachusetts General Hospital (MGH). In celebration of this milestone, a unique Grand Rounds case is presented. A 450-year-old rotund man admitted 60 times presents with a classic triad of periumbilical pain, bilateral plantar burns, and a frozen scalp. Although this triad may at first strike a cord of familiarity among seasoned clinicians, the disease mechanism is truly noteworthy, being clarified only after a detailed occupational history. Ergo, the lessons hark back to the days of yesteryear, when the history and physical served as the cornerstone of Yuletide clinical diagnosis. A discussion of epidemiology and prognosis accompanies a detailed examination of the pathophysiholiday. Although some consider this patient uncouth, as you will see, he is quite a medical sleuth. The long-standing relationship between this patient and the MGH prompted his family to write a letter of appreciation, which will remind the reader of the meaning that our care brings to patients and their families. Harvey Cushing, who completed his internship at the MGH in 1895, professed "A physician is obligated to consider more than a diseased organ, more even than the whole man-he must view the man in his world." We hope this unusual Grand Rounds case intrigues you as it reminds you of Cushing's lesson and wishes you a joyous holiday season.

TI Major Abdominal Surgery in Nursing Home Residents A National Study
SO ANNALS OF SURGERY
LA English
DT Article
ID ACUTE APPENDICITIS; SURGICAL OUTCOMES; OLDER; OCTOGENARIANS; CANCER
AB Objective: To determine surgical risk in nursing home residents undergoing major abdominal surgery.
Background: Recent studies suggest that surgery can be performed safely in the very old. Surgical risk in nursing home residents is poorly understood.
Methods: We used national Medicare claims and the nursing home Minimum Data Set (1999-2006) to identify nursing home residents undergoing surgery (surgery for bleeding duodenal ulcer, cholecystectomy, appendectomy, and colectomy, n = 70,719). We compared operative mortality and use of invasive interventions (mechanical ventilation, intravascular hemodynamic monitoring, feeding tube placement, tracheostomy, and vena cava filters) among nursing home residents to rates among noninstitutionalized Medicare enrollees age 65 and older undergoing the same procedures. (n = 1,060,389). We adjusted for patient characteristics using logistic regression.
Results: Operative mortality among nursing home residents was substantially higher than among noninstitutionalized Medicare enrollees for all procedures (surgery for bleeding duodenal ulcer, 42% versus 26%, adjusted odds ratio (AOR) 1.79; colectomy, 32% versus 13%, AOR 2.06; appendectomy, 12% versus 2%, AOR 3.27; cholecystectomy, 11% versus 3%, AOR 2.65; P < 0.001 for all comparisons). Overall, invasive interventions were more common among nursing home residents than controls (ranging from 18% and 5%, respectively, for cholecystectomy to 55% and 43%, respectively, for surgery for bleeding duodenal ulcer, P < 0.0001 for all comparisons).
Conclusions: Nursing home residents experience substantially higher rates of mortality and invasive interventions after major surgery than other Medicare beneficiaries that are independent of age and measured comorbidities. Our data suggest that the risks of major surgery are substantially higher in nursing home residents and this information should inform decisions of physicians and patients and their families.

AB Objective: Evaluate the value of cytology relative to imaging features in risk assessment for malignancy as defined in the Sendai Guidelines.
Background: The Sendai Guidelines list symptoms, cyst size > 30 mm, dilated main pancreatic duct (MPD) > 6 mm, mural nodule (MN) and "positive" cytology as high risk stigmata for malignancy warranting surgical triage.
Methods: We reviewed clinical, radiological and cytological data of 112 patients with histologically confirmed mucinous cysts of the pancreas evaluated in a single tertiary medical center. Cytology slides were blindly rereviewed and epithelial cells grouped as either benign or high-grade atypia (HGA) [>= high-grade dysplasia]. Histologically, neoplasms were grouped as benign (low-grade and moderate dysplasia) and malignant (in situ and invasive carcinoma). Performance characteristics of cytology relative to other risk factors were evaluated.
Results: Dilated MPD, MN, and HGA were independent predictors of malignancy (p < 0.0001), but not symptoms (p = 0.29) or cyst size > 30 mm (p = 0.51). HGA was the most sensitive predictor of malignancy in all cysts (72%) and in small (<= 30 mm) branch-duct intraductal papillary mucinous neoplasm (BD IPMN; 67%), whereas also being specific (85 and 88%, respectively). MN and dilated MPD were highly specific (> 90%), but insensitive (39%-44%). Cytology detected 30% more cancers in small cysts than dilated MPD or MN and half of the cancers without either of these high-risk imaging features.
Conclusions: Cytology adds value to the radiological assessment of predicting malignancy in mucinous cysts, particularly in small BD IPMN.

MANAGEMENT; PATIENT; DISEASE; SAFETY; COST
AB To assess whether perioperative surgical outcomes associated with thyroid operations were different in those with benign or malignant conditions, we queried the NSQIP, a multi-institutional, risk-adjusted, prospective U.S. database.
A total of 10,838 patients who underwent initial thyroid surgery as their principal operation during 2005-2007 were analyzed. Analysis focused on demographics, preoperative risk factors, operative details, postoperative complications, return to the operating room, and length of surgical stay.
Thirty-three percent of patients had a postoperative diagnosis of malignancy. Mean operating time was 121.8 min (119.3 min benign, 123.0 min malignant, P = .004) and average length of stay 1.16 days (1.12 days benign, vs. 1.21 days malignant, P = .007). Overall morbidity (return to the operating room plus medical complications) was 3.8% for the entire cohort, significantly higher in patients with malignant disease (4.9 vs. 3.3%, respectively, P < .001). On multivariate analysis, American Society of Anesthesiologists class, congestive heart failure (odds ratio [OR] 6.83, 95% confidence interval [CI] 1.81-25.80), dyspnea, and return to the operating room (OR 5.41, 95% CI 3.1-9.45) were significant risk factors for complications, while malignant disease (OR 2.25, 95% CI 1.75-2.9), outpatient status (OR 3.16, 95% CI 2.4-4.17), and other complications (OR 6.46, 95% CI 3.61-11.54) were risk factors for returning to the operating room.
Patients undergoing thyroid surgery for malignancy have a longer length of stay (1.21 days), longer operation times, and return to the operating room at higher rates compared to those with benign disease. Malignancy itself is only an independent risk factor for return to the operating room and not other complications; surgeons may consider keeping those patients overnight for observation.

AB Background. Breast cancer patients may undergo multiple re-excisions after lumpectomy in an attempt to obtain clear margins and avoid mastectomy. We sought to determine the overall local recurrence rate and surgical outcome of patients undergoing two or more re-excisions and to identify predictors of success in attaining clear margins.
Methods. Retrospective review of breast cancer patients who underwent lumpectomy for invasive cancer or ductal carcinoma in situ (DCIS) from 1997 to 2007. Patients who underwent two or more re-excisions were identified and analyzed.
Results. We identified 3,737 patients who underwent lumpectomy over this 10-year period. 875 (23.4%) had close or positive margins requiring a second procedure; 797 (91.1%) had a re-excision; and 78 (8.9%) went directly to mastectomy. Seventy patients underwent multiple re-excisions; 66 patients had 2 re-excisions, 3 patients had 3 re-excisions, and 1 patient had 4 re-excisions. 70% (49/70) of multiple re-excision patients achieved clear margins (26 DCIS, 35 T1, 8 T2, and 1 T3 tumors). All 49 patients who successfully treated with multiple re-excisions received radiation. At a median follow-up of 64 months, 1 of 49 (2.0%) patients had an in-breast recurrence, and 1 of 49 (2.0%) patients had a distant recurrence. Statistically significant risk factors for persistently involved margins after two re-excisions included multifocality and positive lymph node status.
Conclusion. Multiple re-excisions to obtain clear margins are a safe alternative to mastectomy for women with invasive cancer or DCIS. There is an acceptably low risk of local and systemic failure when negative margins are ultimately achieved.

AB Background. Soluble ST2 (sST2), an interleukin (IL)-1 receptor family member, has a role in immunologic tolerance and has also emerged as a biomarker of cardiac stretch and remodeling. The sST2 role in heart transplantation is still unknown.
Methods. From the heart transplantation population at our institution (n = 74), we selected a subset of 26 patients who had an acute rejection episode in the first year after transplantation (35%; 52 +/- 14 years; 76% men). Endomyocardial biopsy (EMB) results obtained at the time of the first rejection episode represented the rejection cohort (n = 26). Each patient served as a control to himself or herself, with EMB without rejection obtained before and after the rejection episode (n = 52). All laboratory measurements and blood samples were obtained at the time of EMB.
Results. sST2 concentrations rose significantly in the context of acute rejection (130 [60 to 238] versus 51 ng/mL [28 to 80]; p = 0.002). Tertile analyses of sST2 concentrations revealed a graded association with rejection (p = 0.002) and repeated measurement analyses showed that sST2 concentrations were significantly modulated by the presence of rejection (p = 0.001). In receiver operator characteristic (ROC) analysis, sST2 had an area under the curve (AUC) of 0.72; the optimal cutoff point was 68 ng/mL (positive predictive value of 53%, negative predictive value of 83%), which predicted acute cellular rejection (odds ratio [OR] 4.9; 95% confidence interval [CI], 1.7 to 14.5; p = 0.004). The addition of sST2 values to those for the N-terminal pro B-type natriuretic peptide (NT-proBNP) resulted in a significant improvement on the integrated discrimination index (IDI) for rejection (relative improvement of 24%; p = 0.021).
Conclusions. sST2 concentrations are modulated by the presence of acute rejection and provide complementary predictive ability to NT-proBNP for the biochemical identification of rejection. (Ann Thorac Surg 2011;92:2118-24) (C) 2011 by The Society of Thoracic Surgeons

ID TRIAL
AB The purpose of this study was to examine health-related quality of life (HRQL) among women with metastatic breast cancer treated on E2100 with paclitaxel or paclitaxel plus bevacizumab. Trial participants (N = 670) completed the Functional Assessment of Cancer Therapy-Breast (FACT-B) pre-treatment and following 4 and 8 cycles of treatment to assess HRQL and breast cancer-specific concerns. A significantly higher proportion of missing FACT-B assessments was observed among patients receiving paclitaxel only, due to faster time to death. To account for this non-ignorable pattern of missing data, we conducted a survival-adjusted HRQL analysis by jointly modeling the longitudinal HRQL outcome and time to non-ignorable dropout using a two-stage model. FACT scores assessing HRQL did not differ following 4 and 8 cycles of treatment; however mean scores on the 9-item Breast Cancer Scale were significantly higher after 4 and 8 cycles of treatment among patients receiving paclitaxel plus bevacizumab. No differences were observed between treatment arms on FACT-B total scores. The addition of bevacizumab was not associated with additional side effect burden from the patient perspective and was associated with a greater reduction in breast cancer-specific concerns. No other differences were noted.

AB Disparities in the receipt of adjuvant chemotherapy for early stage breast cancer is an important factor influencing mortality. We investigated whether greater body mass index (BMI) decreases receipt of adjuvant chemotherapy among women with operable breast cancer. In the NCCN breast cancer outcomes database, we identified women aged a parts per thousand currency sign70 with newly diagnosed stage I, II, or III breast cancer between 1997 and 2007, for whom use of adjuvant chemotherapy was classified as either standard-of-care or discretionary based on their clinical characteristics. Body mass index was assessed in categories (< 18.5 kg/m(2) [underweight], 18.5 to < 25 kg/m(2) [normal], 25 to < 30 kg/m(2) [overweight], 30-39 kg/m(2) [obese], a parts per thousand yen40 kg/m(2) [extreme obese]). Multivariable logistic regression analysis was used to examine the association between BMI and receipt of chemotherapy in each classification group. 9,527 women were eligible for the study; 40% normal weight or less; 31% overweight; 24% obese; and 5% extremely obese. In multivariable analysis, there was no significant association between BMI and receipt of chemotherapy in either classification group. Among women for whom chemotherapy would be considered standard-of-care, older age (P < 0.001), comorbidity (P < 0.001), and non-Hispanic black ethnicity (P = 0.002) were associated with a lower likelihood of receipt of chemotherapy; however, the effect of ethnicity was not modified by obesity. Among women treated for operable breast cancer in the NCCN centers, BMI had no impact on receipt of adjuvant chemotherapy and did not modify the lower likelihood of chemotherapy among non-Hispanic black patients. Further investigation is needed into other factors that contribute to patient disparities in the receipt of chemotherapy in major academic centers.

ID GERMLINE MUTATIONS; CARRIER PROBABILITY; MALIGNANT-MELANOMA; FAMILIAL
MELANOMA; RISK; INDIVIDUALS; PREVALENCE; VARIANTS
AB Background The penetrance of CDKN2A mutations is subject to geographical and latitudinal variation and is presumably dictated by ultraviolet radiation exposure and possibly other co-inherited genetic factors. The frequency of mutations increases with the number of family members affected and the number of primary tumours, and also fluctuates with geography. To date, little is known about the prevalence of CDKN2A mutations in patients with melanoma from Greece.
Objective To characterize the frequency of CDKN2A and CDK4 mutations in a hospital- based population of Greek patients with melanoma. Methods Three hundred and four consecutive single primary melanoma (SPM), nine familial melanoma (FM) and seven multiple primary melanoma cases (MPM) were assessed for sequence variants in exons 1a, 1b and 2 of CDKN2A and exon 2 of CDK4.
Results Germline CDKN2A mutations were detected in 10 of 304 SPM (3.3%), in four of seven MPM (57%) and in two of nine FM (22%) cases. The most common mutation was a Northern European allele (p16 p. R24P) detected in eight individuals. Five previously unreported CDKN2A variants were also identified:) -34G> C, c. 41_ 43delins20bp, c. 301G>C (p. G101R), c.301G> A (p.G101E) and c. 296_297insGACC. We also describe the first report of a CDK4 p. R24H substitution in a Greek family.
Conclusions The Greek population appears to harbour a higher prevalence of the CDKN2A mutation than other reported cohorts. This supports the notion that genetic susceptibility may play a stronger influence in a country with a relatively low incidence of melanoma. Furthermore, the identification of Northern European alleles suggests that gene migration may be responsible, in part, for the observed cases in Greece.

AB Background/aims To determine the vitreous levels of soluble vascular endothelial growth factor receptor (sVEGFR)-1 in patients with various vitreoretinal diseases, and to investigate its correlation with patients' age and the activity of proliferative diabetic retinopathy (PDR).
Methods Vitreous fluid samples were obtained from 187 eyes of 170 patients who underwent vitrectomy for the treatment of idiopathic macular hole (MH, n=30), branch retinal vein occlusion (BRVO, n=37), central retinal vein occlusion (CRVO, n=27), diabetic macular oedema (DME, n=42) and PDR (n=51). The levels of sVEGFR-1 in the vitreous were measured by ELISA.
Results The levels of sVEGFR-1 (pg/ml) were not significantly different among each disease examined (MH 3900.1+/-1188.9, BRVO 3969.7+/-1741.6, CRVO 4897.7+/-1717.7, DME 3856.21+/-1374.7, PDR 4212.3+/-1474.9). There was a significant positive correlation between vitreous concentrations of sVEGFR-1 and patients' age (r=0.430, p<0.01). The sVEGFR-1 concentration in subjects with active PDR was significantly lower than in those with quiescent PDR (p<0.0001), even after being adjusted for age (p<0.0001).
Conclusions Vitreous concentrations of sVEGFR-1 increase with advancing age and are associated with quiescent rather than active PDR even after adjustment for age.

ID LYMPH-NODE
AB Haemangiomas are common benign tumours that are generally detected within the skin, mucosal surfaces and soft tissues. However, intranodal haemangiomas are extremely rare and are among the benign primary vascular abnormalities of the lymph nodes that include lymphangioma, haemangioendothelioma, angiomyomatous hamartoma and haemangiomas. In this case report, we present the imaging and pathological findings of an intranodal haemangioma in the pancreatic head simulating a pancreatic neuroendocrine tumour. To the best of our knowledge, this is the first report of an intranodal haemangioma in this location.

AB Brivanib alaninate, an orally available prodrug of brivanib, is currently under evaluation for the treatment of several malignancies. This study aimed to (1) investigate effects of a high-fat meal on single-dose pharmacokinetics of brivanib in subjects with advanced/metastatic solid tumors and (2) assess the safety and preliminary efficacy of single and multiple doses of brivanib alaninate in this population.
A two-part study was conducted consisting of a single-dose phase (Part A) and a multiple-dose phase (Part B). In Part A, subjects received a single dose of brivanib alaninate (800 mg) either in a fasting state or following ingestion of a high-fat meal (approximately 951 kcal [15% protein, 33% carbohydrate, 52% fat]); serial blood samples were collected for pharmacokinetic analysis up to 48 h post-dosing. In Part B, subjects received brivanib alaninate (800 mg) once daily until discontinuation. Throughout both phases, subjects were evaluated for adverse events (AEs) and best clinical response.
No clinically significant differences in brivanib exposure were observed between fed and fasting subjects in Part A; C (max) was unchanged and AUC(INF) decreased marginally when administered in a fed versus fasted state. In Part A, the incidence of treatment-emergent AEs was broadly similar in a fed or fasted state. Brivanib alaninate was generally well tolerated throughout the study and showed preliminary evidence of antitumor activity.
Consumption of a high-fat meal had no significant effect on brivanib pharmacokinetics. The study further demonstrates the acceptable safety/tolerability profile and antitumor potential of brivanib in patients with advanced malignancies.

AB Background: Contrast-enhanced multislice computed tomographic angiography (MSCTA) detects noncalcified plaque (NCP) in coronary arteries and associated coronary stenoses. However, the clinical relevance of NCP is poorly defined. Objectives: Our goal was to examine the relationship NCP, risk factors (RFs), and clinical follow-up in unselected outpatients undergoing MSCTA. Methods: Five hundred six patients undergoing contrast MSCTA were evaluated for NCP (intraluminal density 25 < Hounsfield units < 130). One hundred twenty-four patients (24.5%) had calcium scores (CAC) of zero. Of these, 111 patients were examined for RFs and followed clinically for a mean of 34 months. Results: Of 124 patients with zero CAC, 111 (89.5%) included 52 (46.8%) with no NCP, 40 (36.0%) with NCP, and mild luminal stenosis, 14 (12.6%) and 5 (4.5%) with NCP causing significant and severe stenosis, respectively. Patients in each group were similar in age but differed significantly in number of RFs. Current or former smokers, hypertensive, and obese patients had more NCP and associated stenosis. At a mean of 34 months, there were no events in the no NCP group, 2/54 (3.7%) events in the NCP without severe stenosis group (one sudden cardiac death and one ventricular tachycardia), and 2/5 (40.0%) patients had revascularization in the NCP with severe stenosis group. Conclusions: (1) In patients with zero CAC, presence of NCP on MSCTA was associated with more RFs, especially smoking, obesity, and hypertension. (2) NCP can result in severe coronary stenosis. (3) NCP detected by MSCTA in patients with zero CAC may identify patients with late cardiac events. (c) 2011 Wiley Periodicals, Inc.

AB Objective A recently developed immunoassay for high-sensitivity measurement of cardiac troponin T (hsTnT) allows measurement at the 99th percentile for a normal population with an assay imprecision < 10%. It is unclear whether such a low cutpoint (14 ng/L) is helpful for long-term risk stratification of patients with an acute coronary syndrome (ACS) undergoing routine early invasive strategy.
Patients and main outcome measures Consecutive patients with ACS admitted to a chest pain unit were studied. The usefulness of hsTnT for early diagnosis of myocardial infarction (MI) and prediction of all-cause death or death/MI over a median of 271 days following presentation was compared against the fourth generation cTnT at the 99th percentile cutpoint.
Results Of 1,384 patients with ACS enrolled, 47.8% had non-ST-segment elevation MI (NSTEMI), 26.4% unstable angina, 21.8% STEMI and 4% had non-ACS. Adjusted risk for all-cause death [adjusted HR 8.26 (95%CI: 1.13-66.33), p = 0.038] and death/MI [adjusted HR 2.71 (95% CI: 1.15-6.38), p = 0.023] were significantly higher with hsTnT above the 99th percentile. In particular, among patients with a standard fourth generation cTnT result below the 99th percentile cutoff (0.01 ng/mL), hsTnT improved risk assessment. Mortality risk associated with an elevated hsTnT was present across the spectrum of ACS, as well as in conditions with hsTnT elevations not related to ACS.
Conclusion hsTnT at the 99th percentile cutoff is useful for the diagnostic evaluation of patients with ACS, and provides strong and independent predictive power for adverse long-term outcomes even after early invasive strategy.

CONSOLIDATION
AB Dream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement (REM) sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from studies of REM sleep. Neuroimaging results show that REM sleep is characterized by a specific pattern of regional brain activity. We demonstrate that this heterogeneous distribution of brain activity during sleep explains many typical features in dreams. Reciprocally, specific dream characteristics suggest the activation of selective brain regions during sleep. Such an integration of neuroimaging data of human sleep, mental imagery, and the content of dreams is critical for current models of dreaming; it also provides neurobiological support for an implication of sleep and dreaming in some important functions such as emotional regulation.

AB Loss of insight is a prominent clinical manifestation of behavioral variant frontotemporal dementia (bvFTD), but its characteristics are poorly understood. Twelve bvFTD patients were compared with 12 Alzheimer's disease (AD) patients on a structured insight interview of cognitive insight (awareness of having a disorder) and emotional insight (concern over having a disorder). Compared to the AD patients, the bvFTD patients were less aware and less concerned about their disorder, and they had less appreciation of its effects on themselves and on others. After corrective feedback ("updating"), the bvFTD patients were just as aware of their disorder as the AD patients but remained unconcerned and unappreciative of its effects. These findings suggest that lack of insight in bvFTD is not due to "anosognosia," or impaired cognitive and executive awareness of disease, but to "frontal anosodiaphoria," or lack of emotional concern over having bvFTD and its impact on themselves and others.

AB Background:
Attention-deficit/hyperactivity disorder (ADHD) and substance use disorder are often comorbid in adults. The effects of ADHD treatment on comorbid alcohol use disorder have not been extensively studied.
Objective:
To assess correlates of ADHD and alcohol use outcomes in ADHD with comorbid alcohol use disorders, via a post-hoc exploratory subgroup analysis of a previously conducted, randomized, double-blind, placebo-controlled study of recently abstinent adults.
Methods:
Adults who had ADHD and alcohol use disorders and were abstinent for 4-30 days were randomized to daily atomoxetine 25-100 mg (mean final dose = 89.9 mg) or placebo for 12 weeks. Changes in ADHD symptoms from baseline to endpoint were assessed using the ADHD Investigator Symptom Rating Scale (AISRS) total score, alcohol use by the timeline followback method, and alcohol cravings by the Obsessive Compulsive Drinking Scale.
Results:
Of 147 subjects receiving atomoxetine (n = 72) or placebo (n = 75) in the primary study, 80 (54%) completed 12 weeks (n = 32 atomoxetine; n = 48 placebo). Improvements in ADHD symptoms on the AISRS correlated significantly with decreases in alcohol cravings (Pearson's r = 0.28; 95% confidence interval [CI] = 0.11-0.43; p = 0.002), and the correlation was most notable with atomoxetine (r = 0.29; CI [0.04-0.51]; p = 0.023) rather than with placebo (r = 0.24; CI [0.00-0.46]; p = 0.055). On-treatment drinking levels correlated with AISRS scores (r = 0.12; CI [0.05-0.19]; p = 0.001). Relapse to alcohol abuse significantly correlated with worse ADHD symptoms on 15 of 18 items of the AISRS in the placebo group (p<0.05 for each).
Conclusions:
No baseline predictor (other than degree of sobriety) of alcohol use or ADHD outcomes emerged. ADHD symptom improvements correlated significantly with reductions in alcohol cravings, and relapse to alcohol abuse correlated significantly with worsening of most ADHD symptoms in the placebo group, but not in the atomoxetine group. This post-hoc subgroup analysis is of a hypothesis-generating nature, and the generalizability of the findings may be limited by exclusion of adults with common ADHD comorbidities from the base study. Further, prospective clinical trials in larger and more heterogeneous patient populations are warranted to confirm or reject these preliminary associations.

AB Older patients with acute myelogenous leukemia (AML) fare much less well than younger patients with the same disease due to a combination of comorbidities and intrinsic disease resistance. Likely due to aging of the US population, the median age of AML patients at diagnosis has increased from 68 to 72 years. AML is a heterogeneous disease, particularly in older patients, making therapeutic decisions challenging. Older patients who are 'fit' for intensive chemotherapy and would have a reasonable chance to benefit based on host and disease characteristics should receive standard induction chemotherapy with 7 days of continuous infusion of cytarabine and at least 60 mg/m(2) daunorubicin daily for 3 days. Therapeutic options for patients who are not candidates for or are not likely to respond to intensive therapy include clofarabine, low intensity chemotherapy such as low dose cytarabine, hypomethylating agents, or investigational agents. For older AML patients in complete remission, post-remission or consolidation chemotherapy with repeat induction or modified high dose cytarabine may offer a small chance for long term disease-free survival. Selected older patients who achieve remission by any means should be considered for reduced-intensity stem cell transplantation which may offer improved chances of cure and survival compared with standard post-remission chemotherapy.

TI IL-21 Is an Antitolerogenic Cytokiine of the Late-Phase Alloimmune

AB OBJECTIVE-Interleukin-21 (IL-21) is a proinflanimatory cytokine that has been shown to affect Treg/Teff balance. However, the mechanism by which IL-21 orchestrates alloimmune response and interplays with Tregs is still unclear.
RESEARCH DESIGN AND METHODS-The interplay between IL-21/IL-21R signaling, FoxP3 expression, and Treg survival and function was evaluated in vitro in immunologically relevant assays and in vivo in allogenic and autoimmune models of islet transplantation.
RESULTS-IL-21R expression decreases on T cells and B cells in vitro and increases in the graft in vivo, while IL-21 levels increase in vitro and in vivo during anti-CD3/anti-CD28 stimulation/allostimulation in the late phase of the alloimmune response. In vitro, IL-21/IL-21R signaling (by using rmIL-21 or genetically modified CD4(+) T cells [IL-21 pOrf plasmid-treated or hIL-21-Tg mice]) enhances the T-cell response during anti-CD3/anti-CD28 stimulation/allostimulation, prevents Treg generation, inhibits Treg function, induces Treg apoptosis, and reduces FoxP3 and FoxP3-dependent gene transcripts without affecting FoxP3 methylation status. In vivo targeting of IL-21/IL-21R expands intragraft and peripheral Tregs, promotes Treg neogenesis, and regulates the antidonor immune response, whereas IL-21/IL-21R signaling in Doxa-inducible ROSA-rtTA-IL-21-Tg mice expands Teffs and FoxP3(-) cells. Treatment with a combination of mIL-21R.Fc and CTLA4-Ig (an inhibitor of the early alloimmune response) leads to robust graft tolerance in a purely alloimmune setting and prolonged islet graft survival in NOD mice.
CONCLUSIONS-IL-21 interferes with different checkpoints of the FoxP3 Treg chain in the late phase of alloimmune response and, thus, acts as an antitolerogenic cytokine. Blockade of the IL-21/IL-21R pathway could be a precondition for tolerogenic protocols in transplantation. Diabetes 60:3223-3234, 2011

AB OBJECTIVE-To investigate the effects of acute hypoglycemia on working memory and brain function in patients with type 1 diabetes.
RESEARCH DESIGN AND METHODS-Using blood oxygen level-dependent (BOLD) functional magnetic resonance imaging during euglycemic (5.0 nunol/L) and hypoglycemic (2.8 mmol/L) hyperinsulinemic clamps, we compared brain activation response to a working-memory task (WMT) in type 1 diabetic subjects (n = 16) with that in age-matched nondiabetic control subjects (n = 16). Behavioral performance was assessed by percent correct responses.
RESULTS-During euglycemia, the WMT activated the bilateral frontal and parietal cortices, insula, thalamus, and cerebellum in both groups. During hypoglycemia, activation decreased in both groups but remained 80% larger in type 1 diabetic versus control subjects (P < 0.05). In type 1 diabetic subjects, higher HbA(1c) was associated with lower activation in the right parahippocampal gyrus and amygdala (R(2) = 0.45, P < 0.002). Deactivation of the default-mode network (DMN) also was seen in both groups during euglycemia. However, during hypoglycemia, type 1 diabetic patients deactivated the DMN 70% less than control subjects (P < 0.05). Behavioral performance did not differ between glycemic conditions or groups.
CONCLUSIONS-BOLD activation was increased and deactivation was decreased in type 1 diabetic versus control subjects during hypoglycemia. This higher level of brain activation required by type 1 diabetic subjects to attain the same level of cognitive performance as control subjects suggests reduced cerebral efficiency in type 1 diabetes.

AB Sirt1, the mammalian ortholog of the yeast Sir2 (silent information regulator 2), was shown to play an important role in metabolism and in age-associated diseases, but its role in skeletal homeostasis and osteoporosis has yet not been studied. Using 129/Sv mice with a germline mutation in the Sirt1 gene, we demonstrate that Sirt1 haplo-insufficient (Sirt1(+/-)) female mice exhibit a significant reduction in bone mass characterized by decreased bone formation and increased marrow adipogenesis. Importantly, we identify Sost, encoding for sclerostin, a critical inhibitor of bone formation, as a novel target of Sirt1. Using chromatin immunoprecipitation analysis, we reveal that Sirt1 directly and negatively regulates Sost gene expression by deacetylating histone 3 at lysine 9 at the Sost promoter. Sost down-regulation by small interfering RNA and the administration of a sclerostin-neutralizing antibody restore gene expression of osteocalcin and bone sialoprotein as well as mineralized nodule formation in Sirt1(+/-) marrow-derived mesenchymal stem cells induced to osteogenesis. These findings reveal a novel role for Sirt1 in bone as a regulator of bone mass and a repressor of sclerostin, and have potential implications suggesting that Sirt1 is a target for promoting bone formation as an anabolic approach for treatment of osteoporosis.

AB Substance P (SP), encoded by the tachykinin 1 (Tac1) gene, is the most potent tachykinin ligand for the high-affinity neurokinin-1 receptor (NK-1R). We previously reported that NK-1R-deficient mice show less weight gain and reduced circulating levels of leptin and insulin in response to a high-fat diet (HFD) and demonstrated the presence of functional NK-1R in isolated human preadipocytes. Here we assessed the effects of SP on weight gain in response to HFD and determined glucose metabolism in Tac1-deficient (Tac1(-/-)) mice. The effect of SP on the expression of molecules that may predispose to reduced glucose uptake was also determined in isolated human mesenteric, omental, and sc preadipocytes. We show that although weight accumulation in response to HFD was similar between Tac1(-/-) mice and wild-type littermates, Tac1(-/-) mice demonstrated lower glucose and leptin and increased adiponectin blood levels and showed improved responses to insulin challenge after HFD. SP stimulated phosphorylation of c-Jun N-terminal kinase, protein kinase C theta, mammalian target of rapamycin, and inhibitory serine insulin receptor substrate-1 phosphorylation in human preadipocytes in vitro. Preincubation of human mesenteric preadipocytes with the protein kinase C theta pseudosubstrate inhibitor reduced insulin receptor substrate 1 phosphorylation in response to SP. Lastly, SP also induced insulin receptor substrate-1 phosphorylation in mature human sc adipocytes. Our results demonstrate an important role for SP in adipose tissue responses and obesity-associated pathologies. These novel SP effects on molecules that enhance insulin resistance at the adipocyte level may reflect an important role for this peptide in the pathophysiology of type 2 diabetes.

AB Obesity is associated with increased monocyte infiltration into adipose tissue and hence increased interaction between adipocytes and monocytes. Although it has been shown that matrix metalloproteinases (MMP) play a critical role in adipose tissue development, the effect of adipocyte and monocyte interaction on MMP production remains largely unknown. Furthermore, although it has been shown that Toll-like receptor 4 (TLR4), a receptor mediating innate immune response, plays an important role in the obesity-associated inflammation and insulin resistance, the effect of TLR4 activation in coculture of adipocytes and monocytes on MMP production has not been investigated. In this study, we cocultured adipocytes with U937 mononuclear cells in a Transwell coculture system and activated TLR4 with lipopolysaccharide or palmitic acid. We found that TLR4 activation and the coculture had a synergistic effect on MMP-1 production. In our further investigation on the underlying mechanisms, it was indicated that adipocyte-derived IL-6 and TLR4 activation acted in concert to synergistically stimulate MMP-1 expression by U937 cells. Taken together, this study has uncovered a novel mechanism potentially involved in MMP-1 up-regulation in adipose tissue, which may facilitate adipose tissue development and obesity.

AB A unique mouse model was developed with elevated endogenous GH (2- to 3-fold) and IGF-I (1.2- to 1.4-fold), due to somatotrope-specific Cre-mediated inactivation of IGF-I receptor (IgfIr) and insulin receptor (Insr) genes (IgfIr, Insr(rGHpCre), referred to as HiGH mice). We demonstrate that the metabolic phenotype of HiGH mice is diet dependent and differs from that observed in other mouse models of GH excess due to ectopic heterologous transgene expression or pituitary tumor formation. Elevated endogenous GH promotes lean mass and whole-body lipid oxidation but has minimal effects on adiposity, even in response to diet-induced obesity. When caloric intake is moderated, elevated GH improves glucose clearance, despite low/normal insulin sensitivity, which may be explained in part by enhanced IGF-I and insulin output. However, when caloric intake is in excess, elevated GH promotes hepatic lipid accumulation, insulin resistance, hyperglycemia, and ketosis. The HiGH mouse model represents a useful tool to study the role endogenous circulating GH levels play in regulating health and disease. (Endocrinology 152: 4825-4837, 2011)

AB Phagocytosis and intracellular processing of mycobacteria by macrophages are complex cellular processes that require spatial and temporal coordination of particle uptake, organelle movement, activation of signaling pathways, and channel-mediated ionic flux. Recent work demonstrated that human macrophage NaV1.5, an intracellular voltage-gated sodium channel expressed on late endosomes, enhances endosomal acidification and phagocytosis. Here, using bacillus Camille-Guerin (BCG) as a model of mycobacterial infection, we examined how this channel regulates phagocytosis and phagosome maturation in human macrophages. Knockdown of NaV1.5 reduced high capacity uptake of labeled BCG. BCG-containing, NaV1.5-expressing cells demonstrated localization of NaV1.5 and Rab-7 positive endosomes and mitochondria to periphagosome regions that was not observed in NaV1.5-deficient cells. Knockdown of the channel reduced the initial calcium response following bacterial challenge and prevented the generation of prolonged and localized calcium oscillations during phagosome maturation. Inhibition of the mitochondrial Na+/Ca2+ exchanger also prevented prolonged calcium oscillations during phagosome maturation. These results suggest that NaV1.5 and mitochondrial-dependent calcium signaling regulate mycobacteria phagocytosis and phagosome maturation in human macrophages through spatial-temporal coordination of calcium signaling within a unique subcellular region.

AB BACKGROUND & AIMS: Induction of oral immune tolerance (OT) blocks proinflammatory responses to orally administered antigens and might be used to treat autoimmune conditions. We investigated whether gut-tropic T cells that express the integrin alpha 4 beta 7 and the chemokine receptor CCR9 are required for OT. METHODS: Skin delayed-type hypersensitivity and experimental autoimmune encephalomyelitis were used to monitor OT in mice. To assess the role of receptors that mediate localization of lymphocytes to the gut (gut-homing receptors) in induction of OT, we studied CCR9(-/-) and beta 7(-/-) mice and also blocked the alpha 4 beta 7 ligand MAdCAM-1 in wild-type mice. We used DEREG and Scurfy mice to assess the role of Foxp3(+) regulatory T cells (Treg) and IL-10(-/-) and IL-10R beta(-/-) mice to examine the role of interleukin (IL)-10 in induction of OT. RESULTS: OT could not be induced in CCR9(-/-) or beta 7(-/-) mice, or when MAdCAM-1 was blocked in wild-type mice, indicating that gut-homing receptors are required for oral tolerization. Consistent with the role of all-trans retinoic acid in inducing gut-homing T cells, OT could not be induced in mice depleted of vitamin A. OT was rescued in CCR9(-/-) mice following adoptive transfer of wild-type T cells, but not CCR9(-/-) or beta 7(-/-) T cells. Gut-homing T cells are therefore necessary and sufficient to induce OT. Wild-type Treg and IL-10 were required to restore OT to CCR9-/- mice, indicating that homing and functional differentiation of IL-10-producing Treg in the gut is required for OT. Conversely, transfer of CCR9(-/-) or beta 7(-/-) T cells to wild-type mice partially inhibited OT. CONCLUSIONS: Expression of CCR9 and alpha 4 beta 7 on T cells and their subsequent localization to the gut is required for induction of OT in mice. Therapies designed to block gut-homing receptors might, under some conditions, interfere with normal tolerogenic mechanisms in the intestinal mucosa.

AB BACKGROUND & AIMS: Glucagon-like peptide-2 (GLP-2) is an intestinal hormone that promotes growth of the gastrointestinal tract. Although insulin-like growth factor (IGF)-1 and the IGF-1 receptor (IGF-1R) are required for GLP-2-induced proliferation of crypt cells, little is known about localization of the IGF-1R which mediates the intestinotropic actions of GLP-2. METHODS: We examined intestinal growth and proliferative responses in mice with conditional deletion of IGF-1R from intestinal epithelial cells (IE-igf1rKO) after acute administration (30-90 min) of GLP-2, in response to 24-hour fasting and re-feeding (to induce GLP-2-dependent adaptation), and after chronic exposure (10 days) to GLP-2. RESULTS: IE-igf1rKO mice had normal small intestinal weight, morphometric parameters, proliferative indices, and distribution of differentiated epithelial cell lineages. Acute administration of GLP-2 increased nuclear translocation of beta-catenin in non-Paneth crypt cells and stimulated the crypt-cell proliferative marker c-Myc in control but not IE-igf1rKO mice. Small intestinal weight, crypt depth, villus height, and crypt-cell proliferation were decreased in control and IE-igf1rKO mice after 24-hour fasting. Although re-feeding control mice restored all of these parameters, re-fed IE-igf1rKO mice had reductions in adaptive regrowth of the villi and crypt-cell proliferation. Control mice that were given chronic GLP-2 had increases in small intestinal weight, mucosal cross-sectional area, crypt depth, villus height, and crypt-cell proliferation. However, the GLP-2-induced increase in crypt-cell proliferation was not observed in IE-igf1rKO mice, and growth of the crypt-villus axis was reduced. CONCLUSIONS: The proliferative responses of the intestinal epithelium to exogenous GLP-2 administration and conditions of GLP-2-dependent adaptive re-growth require the intestinal epithelial IGF-1R.

AB DICER1 is crucial for embryogenesis and early development. Forty different heterozygous germline DICER1 mutations have been reported worldwide in 42 probands that developed as children or young adults, pleuropulmonary blastoma (PPB), cystic nephroma (CN), ovarian sex cord-stromal tumors (especially Sertoli-Leydig cell tumor [SLCT]), and/or multinodular goiter (MNG). We report DICER1 mutations in seven additional families that manifested uterine cervix embryonal rhabdomyosarcoma (cERMS, four cases) and primitive neuroectodermal tumor (cPNET, one case), Wilms tumor (WT, three cases), pulmonary sequestration (PS, one case), and juvenile intestinal polyp (one case). One carrier developed (age 25 years) a pleomorphic sarcoma of the thigh; another carrier had transposition of great arteries (TGA). These observations show that cERMS, cPNET, WT, PS, and juvenile polyps fall within the spectrum of DICER1-related diseases. DICER1 appears to be the first gene implicated in the etiology of cERMS, cPNET, and PS. Young adulthood sarcomas and perhaps congenital malformations such as TGA may also be associated. 32:13811384, 2011. (C) 2011 Wiley Periodicals, Inc.

AB This study evaluates the concordance of treatment summaries (TSs) and survivorship care plans (SCPs) delivered to breast cancer survivors within the LIVESTRONG (TM) Network of Survivorship Centers of Excellence with Institute of Medicine (IOM) recommendations and describes additional structure/process variables.
Seven NCI-designated comprehensive cancer centers and six community-based centers participated. TS/SCPs for 65 patients were rated against IOM recommendations using a study-derived checklist, and surveys were administered to better understand the structure and process of delivering TSs/SCPs.
On average, fewer than half of IOM content recommendations were met for TSs (M = 46%) and less than two thirds for SCPs (M = 59%). No sites achieved a parts per thousand yen75% overall concordance with IOM recommendations for TSs and only two of 13 met this criterion for SCPs. Content domain scores across sites varied widely, as did the number of sites addressing domain content with a parts per thousand yen75% concordance. Nonetheless, resources required for document preparation and delivery were substantial.
Gaps in concordance with IOM recommendations exist even in dedicated survivorship centers. A substantial time burden was also noted. Further research is needed to determine which informational elements are essential, to develop and test strategies for improving efficiency and reach, and to determine if outcomes of survivorship care planning warrant the resources required in their preparation and delivery.
TSs and SCPs have been recommended for all cancer survivors. Essential elements must be determined, approaches made more efficient, outcome improvements demonstrated, and cost-benefit analyses determined before survivors should expect widespread implementation of this recommendation for survivorship care.

AB This study examined the association between sociodemographic, cancer treatment, and care delivery factors on young adult cancer survivors' confidence in managing their survivorship care.
Survivors aged 18-39 years (n = 376) recruited from the LIVESTRONG (TM) Survivorship Center of Excellence Network sites completed a survey assessing self-reported receipt of survivorship care planning, expectations of their providers, and confidence in managing their survivorship care. Multivariate logistic regression identified characteristics of those reporting low confidence in managing their survivorship care.
Mean age was 28 years; mean interval from diagnosis was 9 +/- 8 years. Seventy-one percent reported currently attending an oncology survivorship clinic. Regarding survivorship care planning, 33% did not have copies of their cancer-related medical records, 48% did not have a treatment summary, and 55% had not received a survivorship care plan. Seventy percent identified the oncologist as the most important health care provider for decisions regarding test and treatment decisions while 10% reported using a "shared-care model" involving both primary care providers and oncologists. Forty-one percent were classified as having low confidence in managing survivorship care. In multivariate analysis, low confidence was associated with non-white ethnicity and lack of a survivorship care plan (both p < 0.05).
Findings suggest that provision of survivorship care plans for young adult cancer survivors can be used to improve confidence in managing survivorship care, particularly for ethnic minorities.
Survivors should consider advocating for receipt of a survivorship care plan as it may facilitate confidence as a consumer of survivorship care.

AB Elongation and pathological thickening of the mitral valve (MV) is commonly seen in hypertrophic cardiomyopathy (HCM), and its pathogenic basis is poorly understood. Associated features include mal-positioning of the papillary muscles and MV, as well as systolic anterior motion (SAM) of the MV leaflets, which can worsen the turbulence and dynamic left ventricular outflow tract (LVOT) gradient. Coaptation of the MV leaflets depends on both anterior and posterior leaflet length and position, and failure of either to optimally adapt in this setting can result in mitral regurgitation or worsened LVOT obstruction. The cause of MV enlargement in HCM is not currently understood, and several different hypotheses may be relevant. The lack of correlation between MV size and the severity of left ventricular hypertrophy, as well as the early findings in genetically predisposed individuals with sarcomere mutations, suggest that it may be an intrinsic aspect of HCM in certain individuals. Other evidence points to a reactive process in the setting of excess production of paracrine growth factors in diseased myocardium that may influence valve overgrowth. Improved understanding of the responsible adaptive mechanisms will pave the way for studies targeted on the prevention and treatment of MV disease in HCM.

AB Detrimental changes in body composition are often associated with declining levels of testosterone. Here, we evaluated the notion that multipotent mesenchymal stem cells, that give rise to both fat and muscle tissue, can play a significant role to alter existing body composition in the adult. Transgenic mice with targeted androgen receptor (AR) overexpression in stem cells were employed. Wild-type littermate and AR-transgenic male and female mice were gonadectomized and left untreated for 2 months. After the hypogonadal period, mice were then treated with 5 alpha-dihydrotestosterone (DHT) for 6 weeks. After orchidectomy (ORX), wild-type males have reduced lean mass and increased fat mass compared to shams. DHT treatment was beneficial to partially restore body composition. In wild-type females, ovariectomy (OVX) produced a similar change but there was no improvement with DHT. In targeted AR transgenic mice, DHT treatment increased lean and reduced fat mass to sham levels. In contrast to wild-type females, DHT treatment in female transgenic mice significantly ameliorated the increased fat and decreased lean mass changes that result after OVX. Our results show that DHT administration reduces fat mass and increases lean mass in wildtype males but not females, indicating that wild-type females are not as sensitive to androgen treatment. Because both male and female transgenic mice are more responsive than wild-type, results suggest that body composition remains linked to stem cell fate in the adult and that targeted androgen signaling in stem cells can play a significant role to reverse detrimental changes in body composition in both sexes.

AB We studied the occurrence of intraoperative tidal alveolar recruitment/derecruitment, exhaled nitric oxide (eNO), and lung dysfunction in patients with and without chronic obstructive pulmonary disease (COPD) undergoing coronary artery bypass grafting (CABG).
We performed a prospective observational physiological study at a university hospital. Respiratory mechanics, shunt, and eNO were assessed in moderate COPD patients undergoing on-pump (n = 12) and off-pump (n = 8) CABG and on-pump controls (n = 8) before sternotomy (baseline), after sternotomy and before cardiopulmonary bypass (CPB), and following CPB before and after chest closure. Respiratory system resistance (R (rs)), elastance (E (rs)), and stress index (to quantify tidal recruitment) were estimated using regression analysis. eNO was measured with chemiluminescence.
Mechanical evidence of tidal recruitment/derecruitment (stress index < 1.0) was observed in all patients, with stress index < 0.8 in 29% of measurements. Rrs in on-pump COPD was larger than in controls (p < 0.05). Ers increased in controls from baseline to end of surgery (19.4 +/- A 5.5 to 27.0 +/- A 8.5 ml cm H(2)O(-1), p < 0.01), associated with increased shunt (p < 0.05). Neither Ers nor shunt increased significantly in the COPD on-pump group. eNO was comparable in the control (11.7 +/- A 7.0 ppb) and COPD on-pump (9.9 +/- A 6.8 ppb) groups at baseline, and decreased similarly by 29% at end of surgery(p < 0.05). Changes in eNO were not correlated to changes in lung function.
Tidal recruitment/derecruitment occurs frequently during CABG and represents a risk for ventilator-associated lung injury. eNO changes are consistent with small airway injury, including that from tidal recruitment injury. However, those changes are not correlated with respiratory dysfunction. Controls have higher susceptibility to develop complete lung derecruitment.

AB While oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO(2)) are fundamental parameters of brain health and function, a robust MRI-based mapping of OEF and CMRO(2) amenable to functional MRI (fMRI) has not been established. To address this issue, a novel method called QUantitative Imaging of eXtraction of Oxygen and TIssue Consumption, or QUIXOTIC, is introduced. The key innovation in QUIXOTIC is the use of velocity-selective spin labeling to isolate MR signal exclusively from postcapillary venular blood on a voxel-by-voxel basis. Measuring the T(2) of this venular-targeted blood allows calibration to venular oxygen saturation (Y(v)) via theoretical and experimental T(2) versus blood oxygen saturation relationships. Y(v) is converted to OEF, and baseline CMRO(2) is subsequently estimated from OEF and additional cerebral blood flow and hematocrit measurements. Theory behind the QUIXOTIC technique is presented, and implications of cutoff velocity (V(CUTOFF)) and outflow time parameters are discussed. Cortical gray matter values obtained with QUIXOTIC in 10 healthy volunteers are Y(v) = 0.73 +/- 0.02, OEF 5 0.26 +/- 0.02, and CMRO(2) = 125 +/- 15 mu mol/100 g min. Results are compared to global measures obtained with the T(2) relaxation under spin tagging (TRUST) technique. The preliminary data presented suggest that QUIXOTIC will be useful for mapping Y(v), OEF, and CMRO(2), in both clinical and functional MRI settings. Magn Reson Med 66:1550-1562, 2011.

AB Size-optimized 32-channel receive array coils were developed for five age groups, neonates, 6 months old, 1 year old, 4 years old, and 7 years old, and evaluated for pediatric brain imaging. The array consisted of overlapping circular surface coils laid out on a close-fitting coil-former. The two-section coil former design was obtained from surface contours of aligned three-dimensional MRI scans of each age group. Signal-to-noise ratio and noise amplification for parallel imaging were evaluated and compared to two coils routinely used for pediatric brain imaging; a commercially available 32-channel adult head coil and a pediatric-sized birdcage coil. Phantom measurements using the neonate, 6-month-old, 1-year-old, 4-year-old, and 7-year-old coils showed signal-to-noise ratio increases at all locations within the brain over the comparison coils. Within the brain cortex the five dedicated pediatric arrays increased signal-to-noise ratio by up to 3.6-, 3.0-, 2.6-, 2.3-, and 1.7-fold, respectively, compared to the 32-channel adult coil, as well as improved G-factor maps for accelerated imaging. This study suggests that a size-tailored approach can provide significant sensitivity gains for accelerated and unaccelerated pediatric brain imaging. Magn Reson Med 66:1777-1787, 2011.

AB It has been suggested that internists and family practitioners have somewhat different "disease" perspectives, which may be generated by use of different explanatory models during medical training (pathophysiological vs. biopsychosocial, respectively). This article explores differences between internists and family practitioners in their suggested diagnoses, level of diagnostic certainty, test and prescription ordering, when encountering exactly the same "patient" with coronary heart disease (CHD). Internists were more certain of a CHD diagnosis than family practitioners and were more likely to act on this diagnosis. Family practitioners were more likely to diagnose (and were more certain of) a mental health condition. While many physicians simultaneously entertain several alternate diagnoses, diagnostic certainty has shown to have an important influence on subsequent clinical actions, such as stress testing and prescription of beta blockers. These results may inform future educational strategies designed to reduce diagnostic uncertainty in the face of life-threatening conditions, such as CHD.

AB There is some evidence that hyperglycemia increases the rate of poor outcomes in patients with intracerebral hemorrhage (ICH). We explored the relationship between various parameters of serum glucose concentrations measured during acute hospitalization and hematoma expansion, perihematomal edema, and three month outcome among subjects with ICH.
A post-hoc analysis of a multicenter prospective study recruiting subjects with ICH and elevated systolic blood pressure (SBP) a parts per thousand yen170 mmHg who presented within 6 h of symptom onset was performed. The serum glucose concentration was measured repeatedly up to 5 times over 3 days after admission and change over time was characterized using a summary statistic by fitting the linear regression model for each subject. The admission glucose, glucose change between admission and 24 hour glucose concentration, and estimated parameters (slope and intercept) were entered in the logistic regression model separately to predict the functional outcome as measured by modified Rankin scale (mRS) at 90 days (0-3 vs. 4-6); hematoma expansion at 24 h (a parts per thousand currency sign33 vs. > 33%); and relative perihematomal edema expansion at 24 h (a parts per thousand currency sign40 vs. > 40%).
A total of 60 subjects were recruited (aged 62.0 +/- 15.1 years; 56.7% men). The mean of initial glucose concentration (+/- standard deviation) was 136.7 mg/dl (+/- 58.1). Thirty-five out of 60 (58%) subjects had a declining glucose over time (negative slope). The risk of poor outcome (mRS 4-6) in those with increasing serum glucose levels was over two-fold relative to those who had declining serum glucose levels (RR = 2.64, 95% confidence interval [CI]: 1.03, 6.75). The RRs were 2.59 (95% CI: 1.27, 5.30) for hematoma expansion > 33%; and 1.25 (95% CI: 0.73, 2.13) for relative edema expansion > 40%.
Decline in serum glucose concentration correlated with reduction in proportion of subjects with hematoma expansion and poor clinical outcome. These results provide a justification for a randomized controlled clinical trial to evaluate the efficacy of aggressive serum glucose reduction in reducing death and disability among patients with ICH.

AB Extubation failure in the neurocritical care unit (NCCU) is difficult to predict, and is an important source of prolonged intensive care, exposure to morbidity, and increased cost.
In this observational cohort study in the NCCU of a tertiary care hospital, we examined patients undergoing extubation or tracheostomy with > 6 h of intubation. Observational data were collected at the time of the decision to extubate or pursue tracheostomy. The primary end-point was extubation failure within 72 h.
A total of 378 tracheostomy versus extubation decisions were made on 339 individuals, resulting in 93 tracheostomies and 285 extubations. The extubation failure rate was 48/285 (16.8%). Individuals who underwent extubation had similar GCS scores [median 10T (IQR 10-11), P = 0.21]. Extubation failures had similar rates of pneumonia and fever, chest X-ray (CXR) findings, and admission diagnoses (P = NS). Factors associated with success in univariate analysis included intact gag reflex, normal eye movements, ability to close eyes to command, and ability to cough to command (all P < 0.05). In multivariate analysis, the ability to follow four commands (close eyes, show two fingers, wiggle toes, cough to command) was associated with success (P = 0.01). ROC analysis identified a significant difference in favor of a multivariate model incorporating four commands over GCS alone (P = 0.007).
The ability to follow four commands and other examination criteria were strongly associated with extubation success in this observational study. Modeling suggests that specific neurologic examination parameters provide additional predictive information over GCS alone. A prospective, protocol-driven trial is needed to test and expand these findings.

AB Background. Neuroimaging research has demonstrated medial prefrontal cortex (mPFC) hyporesponsivity and amygdala hyperresponsivity to trauma-related or emotional stimuli in post-traumatic stress disorder (PTSD). Relatively few studies have examined brain responses to the recollection of stressful, but trauma-unrelated, personal events in PTSD. In the current study, we sought to determine whether regional cerebral blood flow (rCBF) abnormalities in mPFC and amygdala in PTSD could be observed during the recollection of trauma-unrelated stressful personal events.
Method. Participants were 35 right-handed male combat veterans (MCVs) and female nurse veterans (FNVs) who served in Vietnam: 17 (seven male, 10 female) with current military-related PTSD and 18 (nine male, nine female) with no current or lifetime PTSD. We used positron emission tomography (PET) and script-driven imagery to study rCBF during the recollection of trauma-unrelated stressful versus neutral and traumatic events.
Results. Voxelwise tests revealed significant between-group differences for the trauma-unrelated stressful versus neutral comparison in mPFC, specifically in the anterior cingulate cortex (ACC). Functional region of interest (ROI) analyses demonstrated that this interaction in mPFC represented greater rCBF decreases in the PTSD group during trauma-unrelated stressful imagery relative to neutral imagery compared to the non-PTSD group. No differential amygdala activation was observed between groups or in either group separately.
Conclusions. Veterans with PTSD, compared to those without PTSD, exhibited decreased rCBF in mPFC during mental imagery of trauma-unrelated stressful personal experiences. Functional neuroanatomical models of PTSD must account for diminished mPFC responses that extend to emotional stimuli, including stressful personal experiences that are not directly related to PTSD.

AB Purpose: To evaluate the consistency of tumor blood volume measurements and antiangiogenic therapy efficacy assessments with a low-molecular-weight gadolinium-based contrast agent (GBCA, gadodiamide) versus an iron oxide nanoparticle (ferumoxytol) in the presence or absence of a loading dose of contrast agent before perfusion magnetic resonance (MR) imaging (preload method).
Materials and Methods: The protocol was approved by the institutional animal care and use committee. U87MG tumor cells were implanted intracerebrally in 13 rats. All 13 rats underwent 11.75-T MR imaging with gadodiamide (60 mu L) 13 days after tumor implantation. The next day, nine rats underwent MR imaging with ferumoxytol (60 mu L). Immediately after ferumoxytol imaging, six rats received bevacizumab (45 mg/kg). MR imaging was repeated 48 hours after bevacizumab treatment with gadodiamide and 72 hours after treatment with ferumoxytol. Each study included three consecutive dynamic susceptibility-weighted contrast material-enhanced (DSC) MR acquisitions, which were performed without preload, with single-dose preload, and with double-dose preload. Tumor relative cerebral blood volume (rCBV) was estimated from each DSC MR acquisition. Two-way repeated measures analysis of variance was performed to test for differences between groups with both contrast agents.
Results: DSC MR imaging with gadodiamide and without preload showed low rCBV (<= 1.75) in nine of the 13 tumors; estimated rCBV increased progressively with both single- and double-dose preloads (P < .001). Conversely, rCBVs obtained with ferumoxytol were high (>1.75) and remained constant with all three acquisitions. The magnitude of rCBV decrease after bevacizumab administration was dependent: on the dose of gadodiamide preload, whereas the magnitude of rCBV decrease with ferumoxytol was constant regardless of whether contrast agent preload was used.
Conclusion: With GBCA, tumor rCBV can be underestimated without preload and becomes dose dependent with preload correction. Conversely, ferumoxytol provides consistent assessment of tumor rCBV and antiangiogenic therapy efficacy. (C) RSNA, 2011

TI Reduction in Radiation Dose in Mercaptoacetyltriglycerine Renography
with Enhanced Planar Processing
SO RADIOLOGY
LA English
DT Article
ID DIFFERENTIAL RENAL-FUNCTION; RECONSTRUCTION; CHILDREN
AB Purpose: To determine the minimum close of technetium 99m ((99m)Tc) mercaptoacetyltriglycerine (MAG3) needed to perform dynamic renal scintigraphy in the pediatric population without loss of diagnostic quality or accurate quantification of renal function and to investigate whether adaptive noise reduction could help further reduce the minimum close required.
Materials and Methods: Approval for this retrospective study was obtained from the institutional review board, with waiver of informed consent:. A retrospective review was conducted in 33 pediatric patients consecutively referred for a (99m)Tc-MAG3 study. In each each patient, a 20-minute dynamic study was performed after administration of 7.4 MBq/kg. Binomial subsampling was used to simulate studies performed with 50%, 30%, 20%, and 10% of the administered dose. Four nuclear medicine physicians independently reviewed the original and subsampled images, with and without noise reduction, for image quality. Two observers independently performed a quantitative analysis of renal function. Subjective rater confidence was analyzed by using a logistic regression model, and the quantitative analysis was performed by using the paired Student t. test.
Results: Reducing the administered close to 30% did not substantially affect image quality, with or without noise reduction. When the dose was reduced to 20%, there was a slight but: significant decrease (P = .0074) in image quality, which resolved with noise reduction. Reducing the dose to 10% caused a decrease in image quality (P = .0003) that was not corrected with noise reduction. However, the dose could be reduced to 10% without a substantial change in the quantitative evaluation of renal function independent of the application of noise reduction.
Conclusion: Decreasing the close of (99m)Tc-MAG3 from 7.4 to 2.2 MBq/kg did not compromise image quality. With noise reduction, the dose can be reduced to 1.5 MBq/kg without subjective loss in image quality. The quantitative evaluation of renal function was not substantially altered, even with a theoretical close as low as 0.74 MBq/kg. (C) RSNA, 2011

AB This study tested the hypothesis that a novel mitochondria-targeted SS-31 peptide attenuates the burn injury-induced apoptosis and endoplasmic reticulum stress and improves insulin sensitivity in the skeletal muscle. Following 30% total body surface area burn or sham burn, mice were injected daily with SS-31 peptide (5 mg/kg body weight), and the rectus abdominis muscles collected on postburn days 1, 3, and 7. The tissues were subjected to various biochemical and immunohistochemical analyses. Treatment with SS-31 peptide prevented burn-induced increases in the caspase 3 activity (P < 0.05) and apoptosis (P < 0.01) on postburn day 7. The SS-31 peptide treatment also prevented the increase in the expression levels of phosphatase and tensin homolog on postburn days 3 and 7. Burn injury-induced increases in the levels of two endoplasmic reticulum stress markers, binding immunoglobulin protein and protein disulfide isomerase, were significantly decreased by the SS-31 peptide treatments on postburn day 7 and on day 3 for binding immunoglobulin protein as well (P < 0.05). The effects of SS-31 appear to be, in part, due to its ability to reduce oxidative stress in burned mice, evidenced by reduced expression of oxidized proteins that were clearly evident on postburn day 7. Our results demonstrate a possible therapeutic potential of SS-31 peptide to ameliorate the adverse effects of burn injury in skeletal muscle.

AB Background Anti-tumour necrosis factor (TNF) antibodies are used to treat both psoriasis and inflammatory bowel disease. The seemingly paradoxical occurrence of psoriasis in patients treated with anti-TNF antibodies is increasingly recognised, but the distinct features associated with inflammatory bowel disease have been incompletely characterised. Aim To identify inflammatory bowel disease patients who developed psoriasis while receiving an anti-TNF antibody at two academic medical centres between 2000 and 2009 and review all published cases of this phenomenon in inflammatory bowel disease. Methods We identified retrospectively all cases of anti-TNF-induced psoriasis in inflammatory bowel disease patients attending two North American healthcare centres. We analysed these cases alongside the published reports of anti-TNF-induced psoriasis. Results We identified 30 subjects who developed a psoriatic rash while receiving anti-TNF therapy for inflammatory bowel disease. Forty-seven per cent (14/30) responded to topical therapy and 23% (7/30) ultimately discontinued the anti-TNF. The new data were combined with those from 120 published cases of anti-TNF-induced psoriasis in inflammatory bowel disease. Anti-TNF-induced psoriasis in inflammatory bowel disease was more common in women (70%). The most common distributions were palmoplantar (43%) and scalp (42%). Complete follow-up in 148 cases showed that 41% responded to topical therapy but 43% required definitive withdrawal of anti-TNF therapy due to the rash. A second anti-TNF was tried in 27 cases with recurrence or persistence of the rash in 14 (52%). Conclusions In this analysis, psoriasiform lesions related to anti-TNF therapy in inflammatory bowel disease occurred most commonly in women. Approximately 41% of those who developed psoriasis while on anti-TNFs responded to topical therapy and were able to continue the drug, while 52% of those treated with an alternate anti-TNF had recurrence of the rash.

To date, no instrument to measure fatigue has been validated in a US inflammatory bowel disease (IBD) population. Aim To determine the reliability and validity of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale in IBD. Methods A total of 209 patients with IBD completed the 13 items of the FACIT-F, alongside laboratory testing and disease activity assessment. Internal consistency was measured by Cronbachs alpha; testretest reliability by the intraclass correlation coefficient (ICC); validity by the correlation of the FACIT-F score with C-reactive protein (CRP) erythrocyte sedimentation rate (ESR), haematocrit (HCT) and disease activity as measured by the Harvey-Bradshaw Index (HBI; CD) and Simple Clinical Colitis Activity Index (SCCAI; UC). Results The mean +/- SD FACIT-F score was 38.9 +/- 11.0 overall (CD 38.6 +/- 11.3; UC 39.4 +/- 10.6). Cronbachs alpha was 0.94. The ICC for first and repeat FACIT-F scores assessed within 180 days without change in disease state was 0.81 (CD 0.78; UC 0.87). FACIT-F scores were lower in patients with active symptoms (CD 4.6 points, 95% CI 2.46.9, P < 0.001; UC 8.5 points, 95% CI 5.511.4, P < 0.001). In UC, FACIT-F scores were correlated with ESR (-0.76, 95% CI -0.89 to -0.50), CRP (-0.72, 95% CI -0.88 to -0.43) and HCT (0.53, 95% CI 0.220.74). Conclusion The FACIT-F scale is a reliable and valid instrument for measuring fatigue in IBD.

AB The heritability of attention deficit hyperactivity disorder (ADHD) is approximately 0.8. Despite several larger scale attempts, genome-wide association studies (GWAS) have not led to the identification of significant results. We performed a GWAS based on 495 German young patients with ADHD (according to DSM-IV criteria; Human660W-Quadv1; Illumina, San Diego, CA) and on 1,300 population-based adult controls (HumanHap550v3; Illumina). Some genes neighboring the single nucleotide polymorphisms (SNPs) with the lowest P-values (best P-value: 8.38 x 10(-7)) have potential relevance for ADHD (e. g., glutamate receptor, metabotropic 5 gene, GRM5). After quality control, the 30 independent SNPs with the lowest P-values (P-values <= 7.57 x 10(-5)) were chosen for confirmation. Genotyping of these SNPs in up to 320 independent German families comprising at least one child with ADHD revealed directionally consistent effect-size point estimates for 19 (10 not consistent) of the SNPs. In silico analyses of the 30 SNPs in the largest meta-analysis so far (2,064 trios, 896 cases, and 2,455 controls) revealed directionally consistent effect-size point estimates for 16 SNPs (11 not consistent). None of the combined analyses revealed a genome-wide significant result. SNPs in previously described autosomal candidate genes did not show significantly lower P-values compared to SNPs within random sets of genes of the same size. We did not find genome-wide significant results in a GWAS of German children with ADHD compared to controls. The second best SNP is located in an intron of GRM5, a gene located within a recently described region with an infrequent copy number variation in patients with ADHD. (C) 2011 Wiley Periodicals, Inc.

AB To understand what conditions may correlate with asthma diagnoses in the lesbian, gay, and bisexual (LGB) population, we used Massachusetts Behavioral Risk Factor Surveillance System data to construct multivariable logistic regression models separately for LGB individuals and heterosexuals. Current or former smoking and obesity were positively associated with history of an asthma diagnosis among both LGB individuals and heterosexuals. Being underweight (negative correlation) and overweight and reporting frequent symptoms of depression in the preceding 30 days also predicted a history of asthma diagnosis among heterosexuals.

AB Objectives. We evaluated associations between mortgage delinquency and changes in health and health-relevant resources over 2 years, with data from the Health and Retirement Study, a longitudinal survey representative of US adults older than 50 years.
Methods. In 2008, participants reported whether they had fallen behind on mortgage payments since 2006 (n=2474). We used logistic regression to compare changes in health (incidence of elevated depressive symptoms, major declines in self-rated health) and access to health-relevant resources (food, prescription medications) between participants who fell behind on their mortgage payments and those who did not.
Results. Compared with nondelinquent participants, the mortgage-delinquent group had worse health status and less access to health-relevant resources at baseline. They were also significantly more likely to develop incident depressive symptoms (odds ratio [OR]=8.60; 95% confidence interval [CI]=3.38, 21.85), food insecurity (OR=7.53; 95% CI=3.01, 18.84), and cost-related medication nonadherence (OR=8.66; 95% CI=3.72, 20.16) during follow-up.
Conclusions. Mortgage delinquency was associated with significant elevations in the incidence of mental health impairments and health-relevant material disadvantage. Widespread mortgage default may have important public health implications. (Am J Public Health. 2011;101:2293-2298. doi:10.2105/AJPH.2011.300245)

AB Objective-Insulin resistance renders macrophages more prone to cholesterol-induced apoptosis by promoting nuclear localization of transcription factor forkhead box transcription factor (Fox) O1. However, FoxO1 also decreases macrophage inflammation, raising the question of how the balance between proapoptotic and antiinflammatory effects is determined. We sought to identify the mechanism whereby FoxO1 dampens inflammation without promoting apoptosis. We hypothesized that nutrient-dependent FoxO1 acetylation plays a role in this process.
Methods and Results-We generated knock-in mice bearing alleles that encode constitutively deacetylated FoxO1 and studied the ex vivo response of primary peritoneal macrophages. We show that macrophages derived from mice homozygous for constitutively deacetylated FoxO1 alleles retain antiinflammatory properties in response to free cholesterol loading, without increasing apoptosis. Deacetylated FoxO1 inhibits free cholesterol-induced Akt phosphorylation and increases levels of the nuclear factor-kappa B precursor p105, decreasing nuclear translocation of nuclear factor-kappa B p65 subunit and dampening mitogen-activated protein/extracellular signal-regulated kinase activation to prevent inflammation.
Conclusion-Deacetylated FoxO1 regulates p105 to prevent macrophage inflammation without causing apoptosis, suggesting a potential novel therapeutic approach to atherosclerosis through FoxO1 deacetylation. (Arterioscler Thromb Vasc Biol. 2011;31:2920-2928.)

AB This study pilot tested a newly developed modular cognitive behavioral therapy (CBT) treatment manual for body dysmorphic disorder (BDD). We tested feasibility, acceptability, and treatment outcome in a sample of 12 adults with primary BDD. Treatment was delivered in weekly individual sessions over 18 or 22 weeks. Standardized clinician ratings and self-report measures were used to assess BDD and related symptoms pre- and posttreatment and at 3- and 6-month follow-ups. At posttreatment, BDD and related symptoms (e.g., mood) were significantly improved. Treatment gains were maintained at follow-up. A relatively low drop-out rate, high patient satisfaction ratings, and patient feedback indicated that the treatment was highly acceptable to patients. To our knowledge, this represents the first test of a broadly applicable, individual psychosocial treatment for BDD.

AB BACKGROUND: Although spiritual care is associated with less aggressive medical care at the end of life (EOL), it remains infrequent. It is unclear if the omission of spiritual care impacts EOL costs. METHODS: A prospective, multisite study of 339 advanced cancer patients accrued subjects from September 2002 to August 2007 from an outpatient setting and followed them until death. Spiritual care was measured by patients' reports that the health care team supported their religious/spiritual needs. EOL costs in the last week were compared among patients reporting that their spiritual needs were inadequately supported versus those who reported that their needs were well supported. Analyses were adjusted for confounders (eg, EOL discussions). RESULTS: Patients reporting that their religious/spiritual needs were inadequately supported by clinic staff were less likely to receive a week or more of hospice (54% vs 72.8%; P=.01) and more likely to die in an intensive care unit (ICU) (5.1% vs 1.0%, P=.03). Among minorities and high religious coping patients, those reporting poorly supported religious/spiritual needs received more ICU care (11.3% vs 1.2%, P=.03 and 13.1% vs 1.6%, P=.02, respectively), received less hospice (43.% vs 75.3% >= 1 week of hospice, P=.01 and 45.3% vs 73.1%, P=.007, respectively), and had increased ICU deaths (11.2% vs 1.2%, P=.03 and 7.7% vs 0.6%, P=.009, respectively). EOL costs were higher when patients reported that their spiritual needs were inadequately supported ($4947 vs $2833, P=.03), particularly among minorities ($6533 vs $2276, P=.02) and high religious copers ($6344 vs $2431, P=.005). CONCLUSIONS: Cancer patients reporting that their spiritual needs are not well supported by the health care team have higher EOL costs, particularly among minorities and high religious coping patients.

AB In human disease induced by Salmonella enterica serovar Typhimurium (S. Typhimurium), transepithelial migration of neutrophils rapidly follows attachment of the bacteria to the epithelial apical membrane. We have previously shown that during S. Typhimurium infection the multidrug resistance-associated protein 2 (MRP2) is highly expressed at the apical surface of the intestinal epithelia, and that it functions as an efflux pump for the potent neutrophil chemoattractant hepoxilin A3. However, the molecular mechanisms regulating its apical localization during active states of inflammation remain unknown. Thus, our objective was to determine the mechanistic basis for the translocation of MRP2 to the apical surface of intestinal epithelial cells during S. Typhimurium infection. We show that suppression of ezrin, through either RNAi or truncation of the C-terminus, results not only in a decrease in S. Typhimurium-induced neutrophil transmigration but also significantly attenuates the apical membrane expression of MRP2 during Salmonella infection. In addition, we determined that S. Typhimurium induces the activation of ezrin via a PKC-a-dependent pathway and that ezrin activation is coupled to apical localization of MRP2. Based on these results we propose that activation of ezrin is required for the apical localization of MRP2 during S. Typhimurium infection.

AB Purpose: To report the long-term outcomes of Boston keratoprosthesis type II implantation in the management of severe ocular surface disease and corneal blindness through a retrospective interventional case series.
Methods: This retrospective review included medical records of patients who underwent Boston keratoprosthesis type II implantation at the Massachusetts Eye and Ear Infirmary from January 1, 2000 through December 31, 2009. The main outcome measures analyzed were visual acuity, keratoprosthesis retention, and postoperative complications.
Results: A total of 29 eyes of 26 patients received a Boston keratoprosthesis type II during the study period. Patients undergoing operation had corneal blindness because of mucous membrane pemphigoid (51.7%), Stevens-Johnson syndrome/toxic epidermal necrolysis (41.4%), or other ocular surface disease (6.9%). Visual acuity after surgery improved to 20/200 or better in 23 eyes (79.3%) and to 20/30 or better in 10 eyes (34.5%). In patients with at least 1 year of follow-up (n = 21), visual acuity of 20/200 or better was maintained in 12 eyes (57.1%). Of 13 eyes followed-up for more than 5 years, 6 eyes (46.2%) had visual acuity of 20/200 or better at the last follow-up examination. Eyes that did not improve to 20/200 or lost vision during the follow-up had end-stage glaucoma, previous retinal detachment, or age-related macular degeneration. Of the total of 29 eyes, 17 devices (58.6%) were retained without extrusion or replacement during a total follow-up time of 107.9 person-years.
Conclusions: The Boston keratoprosthesis type II is a viable option for corneal blindness from severe autoimmune ocular surface diseases.

AB Purpose: The purpose of this study was to evaluate the incidence of glaucoma in eyes with severe chemical burn, before and after keratoprosthesis.
Methods: A retrospective chart review of 28 eyes of 23 patients with severe ocular chemical burns who had undergone Boston Keratoprosthesis (BKPro) surgery at the Massachusetts Eye and Ear Infirmary, between 1990 and 2010. The incidence and severity of the outcome of glaucoma, preoperatively and postoperatively, were reviewed. Related issues, such as type of chemical burn; visual acuity (VA); device retention rate; number and nature of previous, concomitant, and subsequent procedures; and incidence of other postoperative complications, were reviewed for a median follow-up time of 57 months.
Results: The number of eyes with a preoperative history or signs of glaucoma was 21, 9 of which had glaucoma progression after BKPro implantation. In addition, 2 more eyes developed glaucoma postoperatively. Preoperative vision was counting fingers or worse in all eyes. Best-corrected postoperative VA ranged from no light perception to 20/20. Seventeen eyes (61%) achieved 20/60 or better VA at some point during their follow-up, but only 9 (32%) maintained 20/60 at the last follow-up. Of the 28 eyes, 6 had the BKPro replaced once and 1 had it replaced twice. Superimposed, 8 of the most severely burned patients developed retinal detachment postoperatively.
Conclusions: Glaucoma is very common in eyes with severe chemical burns. A keratoprosthesis can rehabilitate vision, but postoperative glaucoma can be difficult to manage.

DE keratoprosthesis; bandage contact lens; deposits; hybrid contact lens
AB Purpose: To describe visually debilitating deposit formation on hydrogel contact lenses routinely used for protection in eyes with keratoprosthesis and to present different types of contact lenses that provide improved deposit resistance.
Methods: Seven keratoprosthesis eyes with a history of rapid and severe deposit formation on their hydrogel lenses were evaluated and documented. The Schirmer values and blink rate of each patient were additionally analyzed. These patients were then subsequently refitted with varying types of contact lenses.
Results: When soft hydrogel lenses were replaced with lenses with water-impermeable centers, dramatically fewer deposits accumulated. Deposit formation on hydrogel lenses did not seem to correlate with low Schirmer values but rather with an insufficient blink rate.
Conclusion: Excellent deposit resistance can be achieved in these patients with the use of hybrid contact lenses with rigid centers or large-diameter entirely rigid contact lenses.

AB Objective: To study the efficacy of topical epigallocatechin gallate (EGCG) for the treatment of dry eye disease (DED).
Methods: Seven-to 8-week-old female C57BL/6 mice were housed in the controlled environment chamber to induce DED. Topical 0.01% or 0.1% EGCG, or vehicle, was applied to the eyes of DED mice. Corneal fluorescein staining and the number of corneal CD11b+ cells were assessed in the different groups. Expression of interleukin-1 beta, tumor necrosis factor-a, chemokine ligand 2, and vascular endothelial growth factor (VEGF)-A/C/D was evaluated by real-time polymerase chain reaction in the corneas at day 9. Corneas were stained for lymphatic vessel endothelial hyaluronan receptor (LYVE)-1 to evaluate lymphangiogenesis, and the terminal transferase dUTP nick end labeling (TUNEL) assay was used to evaluate apoptosis of corneal epithelial cells.
Results: Treatment with 0.1% EGCG showed a significant decrease in corneal fluorescein staining compared with the vehicle (24.6%, P = 0.001) and untreated controls (41.9%, P < 0.001). A significant decrease in the number of CD11b+ cells was observed in 0.1% EGCG-treated eyes, compared with the vehicle in the peripheral (23.3%, P = 0.001) and central (26.1%, P = 0.009) corneas. Treatment with 0.1% EGCG was associated with a significant decrease in the corneal expression of interleukin-1 beta (P = 0.029) and chemokine ligand 2 (P = 0.001) compared with the vehicle and in VEGF-A and VEGF-D levels compared with the untreated group (P = 0.007 and P = 0.048, respectively). EGCG 0.01% also showed a decrease in inflammation at the molecular level but no significant changes in the clinical signs of DED. No cellular toxicity to the corneal epithelium was observed with 0.01% or 0.1% EGCG.
Conclusions: Topical EGCG treatment is able to reduce the clinical signs and inflammatory changes in DED by suppressing the inflammatory cytokine expression and infiltration of CD11b+ cells in the cornea.

AB Objective: Despite improvements in the care of critically ill patients, hospital mortality rate for acute lung injury remains high at approximately 40%. We developed a classification rule to stratify mechanically ventilated patients with acute lung injury according to hospital mortality and compared this rule with the Acute Physiology and Chronic Health Evaluation III prediction.
Patients: We used data of 2,022 participants in Acute Respiratory Distress Syndrome Network trials to build a classification rule based on 54 variables collected before randomization.
Design: We used a classification tree approach to stratify patients according to hospital mortality using a training subset of 1800 participants and estimated expected prediction errors using tenfold crossvalidation. We validated our classification tree using a subset of 222 participants not included in model building and calculated areas under the receiver operating characteristic curves.
Measurements and Main Results: We identified combinations of age (>63 yrs), blood urea nitrogen (>15 mg/dL), shock, respiratory rate (>21 breaths/min), and minute ventilation (>13.9 L/min) as important predictors of hospital mortality at 90 days. The classification tree had a similar expected prediction error in the training set (28% vs. 26%; p = .18) and areas under the receiver operating characteristic curve in the validation set (0.71 vs. 0.73; p = .71) as did a model based on Acute Physiology and Chronic Health Evaluation III.
Conclusions: Our tree-based classification rule performed similarly to Acute Physiology and Chronic Health Evaluation III in stratifying patients according to hospital mortality, is simpler to use, contains risk factors that may be specific to acute lung injury, and identified minute ventilation as a potential novel predictor of death in patients with acute lung injury.

AB Objective: It has been suggested that fluid accumulation may delay recognition of acute kidney injury. We sought to determine the impact of fluid balance on the incidence of nondialysis requiring acute kidney injury in patients with acute lung injury and to describe associated outcomes, including mortality.
Design: Analysis of the Fluid and Catheter Treatment Trial, a factorial randomized clinical trial of conservative vs. liberal fluid management and of management guided by a central venous vs. pulmonary artery catheter.
Setting: Acute Respiratory Distress Syndrome Network hospitals.
Patients: One thousand patients.
Interventions: None.
Measurements and Main Results: The incidence of acute kidney injury, defined as an absolute rise in creatinine of >= 0.3 mg/dL or a relative change of >50% over 48 hrs, was examined before and after adjustment of serum creatinine for fluid balance. The incidence of acute kidney injury before adjustment for fluid balance was greater in those managed with the conservative fluid protocol (57% vs. 51%, p = .04). After adjustment for fluid balance, the incidence of acute kidney injury was greater in those managed with the liberal fluid protocol (66% vs. 58%, p = .007). Patients who met acute kidney injury criteria after adjustment of creatinine for fluid balance (but not before) had a mortality rate that was significantly greater than those who did not meet acute kidney injury criteria both before and after adjustment for fluid balance (31% vs. 12%, p < .001) and those who had acute kidney injury before but not after adjustment for fluid balance (31% vs. 11%, p = .005). The mortality of those patients meeting acute kidney injury criteria after but not before adjustment for fluid balance was similar to patients with acute kidney injury both before and after adjustment for fluid balance (31% vs. 38%, p = .18).
Conclusions: Fluid management influences serum creatinine and therefore the diagnosis of acute kidney injury using creatinine-based definitions. Patients with "unrecognized" acute kidney injury that is identified after adjusting for positive fluid balance have higher mortality rates, and patients who have acute kidney injury before but not after adjusting for fluid balance have lower mortality rates. Future studies of acute kidney injury should consider potential differences in serum creatinine caused by changes in fluid balance and the impact of these differences on diagnosis and prognosis.

AB Aims Point-of-care HbA1c is routine in clinical practice. Comparison of point-of-care HbA1c against laboratory measurements across sites and over time is warranted. Methods One hundred and twenty-one young persons with Type 1 diabetes from four centres provided 450 paired samples collected over 10 months for point-of-care HbA1c and central laboratory-based high-performance liquid chromatography (HPLC) HbA1c determinations. Change in HbA1c over time was assessed by difference from initial to final HbA1c and by growth modelling with annualized slope calculation. Change in HbA1c was categorized as improved (decrease of = 0.5% or negative slope), no change (+/- 0.4% of initial HbA1c or slope = 0) or worsened (increase of = 0.5% or positive slope). Results The 450 paired samples (median of four pairs/patient) were highly correlated (r = 0.97, P < 0.0001), as were time-specific and site-specific pairs (r = 0.94 to 0.98, P < 0.0001). Initial-to-final point-of-care HbA1c and HPLC HbA1c changes were 0.3 +/- 1.1% (range -2.7 to 4.1) and 0.4 +/- 1.2% (-3.9 to 4.5), respectively, with 21% of patients (n = 26) discordant for change categories. ?HbA1c by point-of-care HbA1c vs. HPLC HbA1c differed across the HbA1c range and by = 0.5% absolute difference in ?HbA1c in 14 (54%) of the 26 patients discordant for HbA1c change categories. Mean annual HbA1c slope was 0.4 +/- 1.5% (-5.4 to 4.8) for point-of-care HbA1c and 0.4 +/- 1.6% (-6.9 to 5.2) for HPLC HbA1c, with 18% (n = 22 pairs) discordant for change categories. Conclusions Assessment of absolute HbA1c change may not be different for point-of-care HbA1c compared with HPLC HbA1c; however, misclassification of patients by discrete cut-off values may occur with point-of-care HbA1c compared with HPLC HbA1c determinations.

AB Aims Temporary leadless cardiac pacing using ultrasound energy is feasible in patients. An implantable left ventricular stimulation system being developed for cardiac resynchronization therapy transfers energy from a subcutaneous transmitter to an endocardial receiver through tissue free of interfering lung or rib ('acoustic window'). The aim was to use transthoracic echocardiography to evaluate acoustic window (AW) locations and sizes to determine the implant site for a transmitter, and to investigate clinical predictors of AW location and size.
Methods and results Inclusion criteria were ejection fraction <= 35%, and New York Heart Association functional class III or IV. Acoustic windows were evaluated in intercostal spaces (ICSs) measured in the supine, right lateral, sitting, and standing position during normal respiration and held inspiration. Among 42 patients, at least one adequate AW (>= 2 cm(2)) was identified in 41, 19 patients had adequate AWs in 2 ICSs and 20 patients had adequate AWs in 3. Acoustic window areas were generally smallest in the lateral position with held inspiration and largest in the standing position with normal respiration. Patients with ischaemic cardiomyopathy compared with non-ischaemic cardiomyopathy had smaller heart size [left ventricular end-systolic volume index (LVESVI) 78 +/- 38 mL/m(2) vs. 104 +/- 46 mL/m(2), P = 0.03] but larger AWs in the right lateral position (11.4 +/- 6.5 cm(2) vs. 7.3 +/- 3.4 cm(2), P = 0.01) and standing position (14.0 +/- 7.2 cm(2) vs. 9.4 +/- 3.3 cm(2), P = 0.02).
Conclusions Adequate AWs were present in nearly all patients. Despite smaller hearts, ischaemic cardiomyopathy patients had adequate AWs. A simple procedure performed as an adjunct to pre-implant echocardiography can screen patients and identify transmitter implant locations for an ultrasound-mediated leadless pacing system.

ID FUNCTIONAL DECLINE; LOW MOBILITY; CARE; OUTCOMES
AB Adults over the age of 65 years account for 60% of all hospital admissions and experience consequential negative outcomes directly related to hospitalization. Negative outcomes include falls, delirium, loss in ability to perform basic activities of daily living, and new walking dependence. New walking dependence, defined as the loss in ability to walk independently, occurs in 16%--59% of hospitalized older patients. Nurses are pivotal in promoting functional walking independence in hospitalized patients. However, little is known about how nurses make decisions about whether, when, and how to ambulate older patients. A qualitative study using grounded dimensional analysis was conducted to further explore how nurses make decisions about ambulating hospitalized older adults. Twenty-five registered nurses participated in in-depth interviews lasting 30--60 min. Open, axial, and selective coding was used during the analysis. A conceptual model, which is grounded in how nurses experience ambulating patients, was developed. Multiple categories and dimensions interact and produce an action by the nurse to either restrict mobilization to the level of the bed or progress the patient to ambulation in the hallway. Factors that seemed to have a greater impact on nurses' decisions on whether, when, and how to ambulate were the risk/opportunity assessment, preventing complications, and the presence of a unit expectation to ambulate patients.

ID OLDER-ADULTS; SELF-PERCEPTIONS; HEALTH; DEPRESSION; ATTITUDES; AGEISM
AB Purpose: Expectations regarding aging (ERA) in community-dwelling older adults are associated with personal health behaviors and health resource usage. Clinicians' age expectations likely influence patients' expectations and care delivery patterns; yet, limited research has explored clinicians' age expectations. The Expectations Regarding Aging Survey (ERA-12) was used to assess (a) age expectations in a sample of primary care clinicians practicing in the United States and (b) clinician characteristics associated with ERA-12 scores. Design and Methods: This study was a cross-sectional survey of primary care clinicians affiliated with 5 practice-based research networks, October 2008 to June 2009. A total of 374 of the 1,510 distributed surveys were returned (24.8% response rate); 357 analyzed. Mean respondent age was 48.6 years (SD = 11.6; range 23-87 years); 88.0% physicians, 96.0% family medicine, 94.9% White, and 61.9% male. Results: Female clinicians reported higher ERA-12 scores; clinicians' age expectations decreased with greater years in practice. Among the clinicians, higher ERA-12 scores were associated with higher clinician ratings of the importance of and personal skill in administering preventive counseling and the importance of delivering preventive services. Agreement with individual ERA-12 items varied widely. Implications: Unrealistically high or low ERA could negatively influence the quality of care provided to patients and patients' own age expectations. Research should examine the etiology of clinicians' age expectations and their association with older adult diagnoses and treatment. Medical education must incorporate strategies to promote clinician attitudes that facilitate successful patient aging.

AB Recent studies have demonstrated greater risks of cardiovascular events and mortality among persons who have lower 25-hydroxyvitamin D (25-OHD) and higher parathyroid hormone (PTH) levels. We sought to evaluate the association between markers of mineral metabolism and sudden cardiac death (SCD) among the 2312 participants from the Cardiovascular Health Study who were free of clinical cardiovascular disease at baseline. We estimated associations of baseline 25-OHD and PTH concentrations individually and in combination with SCD using Cox proportional hazards models after adjustment for demographics, cardiovascular risk factors, and kidney function. During a median follow-up of 14 years, there were 73 adjudicated SCD events. The annual incidence of SCD was greater among subjects who had lower 25-OHD concentrations, 2 events per 1000 for 25-OHD >= 20 ng/mL and 4 events per 1000 for 25-OHD <20 ng/mL. Similarly, SCD incidence was greater among subjects who had higher PTH concentrations, 2 events per 1000 for PTH <65 pg/mL and 4 events per 1000 for PTH >= 65 pg/mL. Multivariate adjustment attenuated associations of 25-OHD and PTH with SCD. Finally, 267 participants (11.7% of the cohort) had high PTH and low 25-OHD concentrations. This combination was associated with a >2-fold risk of SCD after adjustment (hazard ratio: 2.19 [95% CI: 1.17-4.10]; P=0.017) compared with participants with normal levels of PTH and 25-OHD. The combination of lower 25-OHD and higher PTH concentrations appears to be associated independently with SCD risk among older adults without cardiovascular disease.

AB Clinical relevance of a genetic predisposition to elevated blood pressure was quantified during the transition from childhood to adulthood in a population-based Finnish cohort (N=2357). Blood pressure was measured at baseline in 1980 (age 3-18 years) and in follow-ups in 1983, 1986, 2001, and 2007. Thirteen single nucleotide polymorphisms associated with blood pressure were genotyped, and 3 genetic risk scores associated with systolic and diastolic blood pressures and their combination were derived for all of the participants. Effects of the genetic risk score were 0.47 mm Hg for systolic and 0.53 mm Hg for diastolic blood pressures (both P<0.01). The combination genetic risk score was associated with diastolic blood pressure from age 9 years onward (beta=0.68 mm Hg; P=0.015). Replications in 1194 participants of the Bogalusa Heart Study showed essentially similar results. The participants in the highest quintile of the combination genetic risk score had a 1.82-fold risk of hypertension in adulthood (P<0.0001) compared with the lowest quintile, independent of a family history of premature hypertension. These findings show that genetic variants are associated with preclinical blood pressure traits in childhood; individuals with several susceptibility alleles have, on average, a 0.5-mm Hg higher blood pressure, and this trajectory continues from childhood to adulthood.

AB Recent studies have shown that low serum 25-hydroxyvitamin D (25[OH] D) level is a risk factor for preeclampsia. The clinical significance of in vitro findings that vitamin D regulates vascular endothelial growth factor production is unclear. We sought to determine whether there is an association between midgestation serum 25(OH)D levels and angiogenic factor activity and to compare their predictive value for the development of severe preeclampsia. We conducted a nested case-control study of women with severe preeclampsia (n = 41) versus women with uncomplicated term birth (n = 123) who had second trimester genetic screening (15-20 weeks). Using banked frozen serum, we measured levels of 25(OH)D, vascular endothelial growth factor, soluble fms-like tyrosine kinase 1, and placental growth factor and compared their correlations and predictive values. We found no correlation between serum 25(OH)D and angiogenic factors levels. 25(OH)D alone was comparable to vascular endothelial growth factor and soluble fms-like tyrosine kinase 1/placental growth factor ratio as a predictive marker for severe preeclampsia. A composite of both 25(OH)D level and soluble fms-like tyrosine kinase 1/placental growth factor ratio was more predictive than either alone (area under curve: 0.83 versus 0.74 and 0.67, respectively). In conclusion, combining midpregnancy 25(OH)D level with soluble fms-like tyrosine kinase 1/placental growth factor ratio provides a better prediction for the development of severe preeclampsia.

AB Objectives: To describe the longitudinal course of three core eating disorder symptoms-low body weight, binge eating, and purging-in women with anorexia nervosa (AN) and bulimia nervosa (BN) using a novel statistical approach.
Method: Treatment-seeking women with AN (n = 136) or BN (n = 110) completed the Eating Disorders Longitudinal Interval Follow-Up Evaluation interview every 6 months, yielding weekly eating disorder symptom data for a 5-year period. Semiparametric mixture modeling was used to identify longitudinal trajectories for the three core symptoms.
Results: Four individual trajectories were identified for each eating disorder symptom. The number and general shape of the individual trajectories was similar across symptoms, with each model including trajectories depicting stable absence and stable presence of symptoms as well as one or more trajectories depicting the declining presence of symptoms. Unique trajectories were found for low body weight (fluctuating presence) and purging (increasing presence). Conjunction analyses yielded the following joint trajectories: low body weight and binge eating, low body weight and purging, and binge eating and purging.
Discussion: The course of individual eating disorder symptoms among patients with AN and BN is highly variable. Future research identifying clinical predictors of trajectory membership may inform treatment and nosological research. (C) 2010 by Wiley Periodicals, Inc.

AB Objective: To investigate the relation of maternal and peer attitudes and behaviors to changes in eating disorder risk factors and symptoms in adolescent females.
Method: We tested whether maternal and peer eating attitudes, behaviors, and deficits in social support at baseline predicted subsequent increases in eating disorder risk factors and symptoms among 483 late adolescent females followed over 3 years.
Results: Data provide partial support for hypotheses, as eating disorder risk factors and symptoms increased over time and maternal thin ideal internalization significantly predicted a future increases in adolescent bulimic symptoms. There were no significant predictors of adolescent thin ideal internalization or body dissatisfaction.
Discussion: Findings only partially support the hypothesis that unhealthy attitudes and behaviors of mothers increase risk for eating disorder symptoms in their late adolescent daughters. These results underscore why eating disorder prevention programs should be based on risk factor research that has used prospective and rigorous designs. (C) 2011 by Wiley Periodicals, Inc.

AB This is the first investigation of the relationship between parental age and extreme social-communicative autistic traits in the general population. The parents of 5,246 children in the Avon Longitudinal Study of Parents and Children (ALSPAC) completed the Social and Communication Disorders Checklist (SCDC). The association between parental age and SCDC scores was assessed in the full sample and among high scoring individuals (e.g. top 5%, 1%). There was no association between parental age and social-communicative autistic traits in the general population. Neither maternal nor paternal age was associated with extreme scores. These findings suggest that advanced parental age does not confer increased risk for extreme social and communication impairment assessed quantitatively.

AB Early treatment with intravenous (IV) recombinant tissue plasminogen activator/alteplase (tPA) is associated with improved outcomes for patients with an acute ischemic stroke. Thus, rapid triage and treatment of stroke patients are essential, with a goal of door-to-needle time of no more than 60 minutes. We sought to identify best practices associated with faster treatment among hospitals participating in Get With the Guidelines-Stroke. Qualitative telephone interviews were conducted to elicit strategies being used by these centers to assess, treat, and monitor stroke patients treated with IV tPA. We sequentially carried out these interviews until we no longer identified novel factors. Interviews were conducted with 13 personnel at 7 top-performing U. S. hospitals. With the use of a hermeneutic-phenomenological framework, 5 distinct domains associated with rapid IV tPA delivery were identified. These included (a) communication and teamwork, (b) process, (c) organizational culture, (d) performance monitoring and feedback, and (e) overcoming barriers.

AB Treatment with statins, inhibitors of HMG-CoA reductase, extends the survival of septic mice. However, the molecular mechanisms underlying the cholesterol-lowering, independent beneficial effects of statins in sepsis are poorly understood. The inhibition of protein isoprenylation, namely farnesylation and geranylgeranylation, has been proposed as a mediator of the pleiotropic protective effects of statins, although direct evidence is lacking. Major features of sepsis-induced immune suppression include T-cell dysfunction, which is characterized by apoptosis of splenic T cells, increased CD4(+)Foxp3(+) regulatory T cells (Tregs), and suppression of type 1 helper T-cell response [e.g., interferon-gamma (IFN-gamma) secretion] in mice. Here, we show that the induction of sepsis by cecal ligation and puncture (CLP) resulted in increases in farnesyltransferase activity and farnesylated proteins in the spleen relative to sham operation. Treatment with farnesyltransferase inhibitor N-[4-[2(R)-amino-3-mercaptopropyl]amino-2-phenylbenzoyl]methionine methyl ester trifluoroacetate salt (FTI-277) (25 mg/kg b.wt. i.p.) at 2 h after CLP blocked the increase in farnesylated proteins and improved survival and bacterial clearance of septic mice. FTI-277 reverted to or mitigated sepsis-induced apoptosis in spleen and thymus, increased splenic CD4(+)Foxp3(+) Tregs, and suppressed IFN-gamma secretion and proliferation of splenocytes in response to anti-CD3+CD28 antibodies in mice. Moreover, FTI-277 promoted macrophage phagocytotic activity in septic mice. These results indicate that elevation in protein farnesylation plays a role in derangements in immune function and mortality of septic mice. These findings suggest that prevention of immune dysfunction might contribute to FTI-277-induced improvement in survival of septic mice. These data highlight protein farnesyltransferase as a novel potential molecular target to reduce the mortality of patients with sepsis.

AB Objective: To assign responsibility for variations in small area hospitalization rates to specific hospitals and to evaluate the Roemer's Law in a way that does not artificially induce correlation between bed supply and utilization.
Data Sources/Study Setting: We used data on hospitalizations and outpatient treatment for 15 medical conditions of nonmanaged care Part B eligible Medicare enrollees of 65 years and older in Massachusetts in 2000.
Study Design: We used a Bayesian model to estimate each hospital's pool of potential patients and the fraction of the pool hospitalized (its propensity to hospitalize, PTH). To evaluate the Roemer's Law, we calculated the correlation between hospitals' PTH and beds per potential patient. Patient severity was measured using All Patient Refined Diagnosis Related Groups.
Results: We show that our approach does not artificially induce a correlation between beds and utilization whereas the traditional approach does. Nevertheless, our approach indicates a strong relationship between PTH and beds (r = 0.56). Eighteen (of 66) hospitals had a high PTH that differed significantly from 16 hospitals with a low PTH. Average patient severity in the high PTH hospitals was lower than in the low PTH hospitals. Although the difference was not statistically significant (P = 0.12), there was a medium effect size (0.58).
Discussion: Variation across hospitals in the PTH index, the strong relationship between beds and the PTH, and the lack of relationship between severity and the PTH suggest the importance of policies that limit bed growth of high PTH hospitals and create incentives for high PTH hospitals to reduce hospitalizations.

AB Stem cells have a number of properties, which make them excellent candidates for the treatment of various neurologic disorders, the most important of which being their ability to migrate to and differentiate predictably at sites of pathology in the brain. The disease-directed migration and well-characterized differentiation patterns of stem cells may eventually provide a powerful tool for the treatment of both localized and diffuse disease processes within the human brain. A thorough understanding of the molecular mechanisms governing their migratory properties and their choice between different differentiation programs is essential if these cells are to be used therapeutically in humans. This review focuses on summarizing the migration and differentiation of therapeutic neural and mesenchymal stem cells in different disease models in the brain and also discusses the promise of these cells to eventually treat various forms of neurologic disease.

AB Neuronal signaling consumes much of the brain energy, mainly through the restoration of the membrane potential (MP) by ATP-consuming ionic pumps. We have reported that, compared with waking, ATP levels increase during the initial hours of natural slow-wave sleep, a time with prominent electroencephalogram (EEG) delta oscillations (0.5-4.5 Hz). We have hypothesized that there is a delta oscillation-ATP increase coupling, since, during delta waves, neurons exhibit a prolonged hyperpolarizing phase followed by a very brief phase of action potentials. However, direct proof of this hypothesis is lacking, and rapid changes in EEG/neuronal activity preclude measurement in the naturally sleeping brain. Thus, to induce a uniform state with pure delta oscillations and one previously shown to be accompanied by a similar pattern of neuronal activity during delta waves as natural sleep, we used ketamine-xylazine treatment in rats. We here report that, with this treatment, the high-energy molecules ATP and ADP increased in frontal and cingulate cortices, basal forebrain, and hippocampus compared with spontaneous waking. Moreover, the degree of ATP increase positively and significantly correlated with the degree of EEG delta activity. Supporting the hypothesis of decreased ATP consumption during delta activity, the ATP-consuming Na(+)-K(+)-ATPase mRNA levels were significantly decreased, whereas the mRNAs for the ATP-producing cytochrome c oxidase (COX) subunits COX III and COX IVa were unchanged. Taken together, these data support the hypothesis of a cortical delta oscillation-dependent reduction in ATP consumption, thus providing the brain with increased ATP availability, and likely occurring because of reduced Na(+)-K(+)-ATPase related energy consumption.

AB Chemokines are chemotactic cytokines that regulate cell migration and are thought to play an important role in a broad range of inflammatory diseases. The availability of chemokine receptor blockers makes them an important therapeutic target. In vitro, chemokines are shown to modulate neurotransmission. However, it is not very clear if chemokines play a role in behavior and cognition. Here we evaluated the role of CC chemokine receptor 5 (CCR5) in various behavioral tasks in mice using Wt (Ccr5(+/+)) and Ccr5-null (Ccr5(-/-)) mice. Ccr5(-/-) mice showed enhanced social recognition. Administration of CC chemokine ligand 3 (CCL3), one of the CCR5-ligands, impaired social recognition. Since the social recognition task is dependent on the sense of olfaction, we tested olfactory recognition for social and non-social scents in these mice. Ccr5(-/-) mice had enhanced olfactory recognition for both these scents indicating that enhanced performance in social recognition task could be due to enhanced olfactory recognition in these mice. Spatial memory and aversive memory were comparable in Wt and Ccr5(-/-) mice. Collectively, these results suggest that chemokines/chemokine receptors might play an important role in olfactory recognition tasks in mice and to our knowledge represents the first direct demonstration of an in vivo role of CCR5 in modulating social behavior in mice. These studies are important as CCR5 blockers are undergoing clinical trials and can potentially modulate behavior. (C) 2011 IBRO. Published by Elsevier Ltd. All rights reserved.

AB There is a consensus that active (REM) sleep (AS) is controlled by cholinergic projections from the laterodorsal and pedunculopontine tegmental nuclei (LDT/PPT) to neurons in the nucleus pontis oralis (NPO) that generate AS (i.e. AS-Generator neurons). The present study was designed to provide evidence that other projections to the NPO, such as those from the amygdala, are also capable of inducing AS. Accordingly, the responses of neurons, recorded intracellularly in the NPO, were examined following stimulation of the ipsilateral central nucleus of the amygdala (CNA) in urethane-anesthetized rats. Single pulse stimulation in the CNA produced an early, fast depolarizing potential (EPSP) in neurons within the NPO. The mean latency to the onset of these excitatory postsynaptic potentials (EPSPs) was 3.6 +/- 0.2 ms. A late, small-amplitude inhibitory synaptic potential (IPSP) was present following EPSPs in a portion of the NPO neurons. Following stimulation of the CNA with a train of 8-10 pulses, NPO neurons exhibited a sustained depolarization (5-10 my) of their resting membrane potential. When single subthreshold intracellular depolarizing current pulses were delivered to NPO neurons, CNA-induced EPSPs were sufficient to promote the discharge of these cells. Stimulation of the CNA with a short train of stimuli induced potent temporal facilitation of EPSPs in NPO neurons. Two forms of synaptic plasticity were revealed by the patterns of response of NPO neurons following stimulation of the CNA: paired-pulse facilitation (PPF) and post-tetanic potentiation (PIP). Six of recorded NPO neurons were identified morphologically with neurobiotin. They were medium to large, multipolar cells with diameters >20 mu M, which resemble AS-on cells in the NPO. The present results demonstrate that amygdalar projections are capable of exerting a powerful excitatory postsynaptic drive that activates NPO neurons. Therefore, we suggest that the amygdala is capable of inducing AS via direct projections to AS-Generator neurons in the NPO. (C) 2011 IBRO. Published by Elsevier Ltd. All rights reserved.

AB Background
Dysfunction of regulatory T (Treg) cells has been detected in diverse inflammatory disorders, including chronic graft-versus-host disease (GVHD). Interleukin-2 is critical for Treg cell growth, survival, and activity. We hypothesized that low-dose interleukin-2 could preferentially enhance Treg cells in vivo and suppress clinical manifestations of chronic GVHD.
Methods
In this observational cohort study, patients with chronic GVHD that was refractory to glucocorticoid therapy received daily low-dose subcutaneous interleukin-2 (0.3x10(6), 1x10(6), or 3x10(6) IU per square meter of body-surface area) for 8 weeks. The end points were safety and clinical and immunologic response. After a 4-week hiatus, patients with a response could receive interleukin-2 for an extended period.
Results
A total of 29 patients were enrolled. None had progression of chronic GVHD or relapse of a hematologic cancer. The maximum tolerated dose of interleukin-2 was 1x106 IU per square meter. The highest dose level induced unacceptable constitutional symptoms. Of the 23 patients who could be evaluated for response, 12 had major responses involving multiple sites. The numbers of CD4+ Treg cells were preferentially increased in all patients, with a peak median value, at 4 weeks, that was more than eight times the baseline value (P<0.001), without affecting CD4+ conventional T (Tcon) cells. The Treg: Tcon ratio increased to a median of more than five times the baseline value (P<0.001). The Treg cell count and Treg: Tcon ratio remained elevated at 8 weeks (P<0.001 for both comparisons with baseline values), then declined when the patients were not receiving interleukin-2. The increased numbers of Treg cells expressed the transcription factor forkhead box P3 (FOXP3) and could inhibit autologous Tcon cells. Immunologic and clinical responses were sustained in patients who received interleukin-2 for an extended period, permitting the glucocorticoid dose to be tapered by a mean of 60% (range, 25 to 100).
Conclusions
Daily low-dose interleukin-2 was safely administered in patients with active chronic GVHD that was refractory to glucocorticoid therapy. Administration was associated with preferential, sustained Treg cell expansion in vivo and amelioration of the manifestations of chronic GVHD in a substantial proportion of patients.

ID BRAIN-STEM
AB Objective: To systematically characterize unilateral tinnitus typically lasting less than a minute.
Study Design: Observational study.
Setting: Outpatient clinic in a tertiary referral hospital.
Patients: Study I: 62 unselected adults. Study II: 74 adults with sudden brief unilateral tapering tinnitus (SBUTT).
Interventions: Study I: Structured interview regarding SBUTTs and other types of tinnitus. Study II: Maintaining an SBUTT log for 4 consecutive months.
Main Outcome Measures: Study I: Retrospective prevalence of SBUTTs. Study II: Prospective frequency and characteristics of SBUTTs.
Results: Study I: 76% of the participants recalled having at least one SBUTT in the past. There was no significant difference in the incidence of SBUTTs with respect to handedness, age, sex, the presence or absence of chronic tinnitus, whether tinnitus could be brought on by exposure to loud sounds, or whether auditory perception could be modulated with strong muscle contractions of the neck or jaw. Study II: SBUTTs mean rate was 1.2 per month ( range, 0-11.5). The rate in people with chronic tinnitus was twice that of those without chronic tinnitus. Right ear SBUTTs predominated nearly 2 to 1. Pitch estimates ranged between 0.1 and 4.4 kHz; 75% of SBUTTs lasted 25 seconds or less. A quarter occurred with simultaneous ear fullness.
Conclusion: In the 76% of adults with SBUTTs, the average rate of occurrence was about once a month. SBUTTs are twice as common for the right ear as the left. One of 4 SBUTTs occurs with ear fullness. A quarter of adults never recalled ever having an SBUTT.

AB Hypothesis: The sound-induced motion of the tympanic membrane has features that are most consistent with modal responses to a uniform stimulus.
Background: Conceptual models of the coupling of tympanic membrane motion to the ossicular chain can be classified as either modal responses to a uniform stimulation of the entire membrane or traveling wave models in which sound energy is captured at the membrane's rim and travels along the surface to the umbo. The stroboscopic holography technique we use can separate strongly modal or traveling wave-dominated motions of the tympanic membrane surface.
Methods: We use computer-aided optoelectronic holography with stroboscopic illumination to measure the magnitude and phase of the sound-induced motion of more than 40,000 points on the surface of the tympanic membrane in cadaveric human temporal bones. Our techniques are sensitive to motions of the membrane as small as 0.01 mu m and allow determinations of membrane displacement at frequencies as large as 20 kHz.
Results: We report clear signs of both modal tympanic membrane responses and traveling waves on the human tympanic membrane. Modal responses are seen throughout the frequency range, whereas the traveling waves are most apparent between 2 and 8 kHz. In general, the magnitudes of the traveling waves are small compared with the modal magnitudes.
Conclusion: Much of the motion of the tympanic membrane is well approximated by modal motions of the tympanic membrane surface. This conclusion has implications for eardrum pathology and its treatment.

AB The suicide safety plan is a plan of action created by the clinician and patient that essentially charts the course of what the patient should do if he/she begins to experience suicidal urges. It is important for clinicians to learn how to implement a safety plan so that they can offer this service to their patients and teach their colleagues and associates about suicide safety planning. The safety plan is a great tool employed to help patients with suicidal urges, but trainees-clinicians and clinician associates alike - should fully understand that it is not a form of treatment. However, since an effective treatment for suicidality does not exist, practitioners should definitely use suicide safety planning. Although more resources are now being provided to individuals with suicidal behavior, more research needs to be done to develop new, effective methods of treatment and prevention of suicidal behavior.

AB Two dual-task experiments (replications of Experiments 1 and 2 in Fedorenko, Gibson, & Rohde, Journal of Memory and Language, 56, 246-269 2007) were conducted to determine whether syntactic and arithmetical operations share working memory resources. Subjects read object- or subject-extracted relative clause sentences phrase by phrase in a self-paced task while simultaneously adding or subtracting numbers. Experiment 2 measured eye fixations as well as self-paced reaction times. In both experiments, there were main effects of syntax and of mathematical operation on self-paced reading times, but no interaction of the two. In the Experiment 2 eye-tracking results, there were main effects of syntax on first-pass reading time and total reading time and an interaction between syntax and math in total reading time on the noun phrase within the relative clause. The findings point to differences in the ways individuals process sentences under these dual-task conditions, as compared with viewing sentences during "normal" reading conditions, and do not support the view that arithmetical and syntactic integration operations share a working memory system.

AB Continuous positive airway pressure (CPAP) is a highly efficacious treatment for obstructive sleep apnea (OSA) but adherence to the treatment limits its overall effectiveness across all age groups of patients. Factors that influence adherence to CPAP include disease and patient characteristics, treatment titration procedures, technological device factors and side effects, and psychological and social factors. These influential factors have guided the development of interventions to promote CPAP adherence. Various intervention strategies have been described and include educational, technological, psychosocial, pharmacological, and multi-dimensional approaches. Though evidence to date has led to innovative strategies that address adherence in CPAP-treated children, adults, and older adults, significant opportunities exist to develop and test interventions that are clinically applicable, specific to sub-groups of patients likely to demonstrate poor adherence, and address the multi-factorial nature of CPAP adherence. The translation of CPAP adherence promotion interventions to clinical practice is imperative to improve health and functional outcomes in all persons with,CPAP-treated OSA. (C) 2011 Elsevier Ltd.

We developed tuning software that can customize control interfaces for individuals with upper-limb impairments. This study compared the differences in each parameter among different diagnostic groups.

The participants were classified into the following groups: athetoid cerebral palsy, spastic cerebral palsy, multiple sclerosis, upper-limb spasticity, and control. We used a validated tuning software protocol to customize an isometric joystick before a virtual tracing or driving task. Tuning parameters were then compared across groups.
Results: Seventy-five subjects were included. Gain, the parameter responsible for force-to-output ratios, in each directional axis (leftward gain: P = 0.018; rightward gain: P = 0.003; reverse gain: P = 0.007; forward gain: P = 0.014) was significantly different across the diagnostic groups. Post hoc analyses showed that the control group required smaller leftward gain than spastic cerebral palsy, multiple sclerosis and upper-limb spasticity groups and smaller gain in all other directions compared with spastic cerebral palsy.
Conclusions: Gain may be a useful parameter in tuning by clinicians, and efforts aimed at gain customization may aid the development of commercially available tuning software packages.

AB We undertook this study to investigate whether treatment with a higher dose of trimethoprim-sulfamethoxazole (TMP/SMX) led to greater clinical resolution in patients with skin and soft tissue infections (SSTIs) caused by methicillin-resistant Staphylococcus aureus (MRSA). A prospective, observational cohort with nested case-control study was performed at a public tertiary health system. Among patients with MRSA SSTIs during the period from May 2008 to September 2008 who received oral monotherapy with TMP/SMX and whose clinical outcome was known, the clinical characteristics and outcomes were compared between patients treated with a high dose of TMP/SMX (320 mg/1,600 mg twice daily) for 7 to 15 days and patients treated with the standard dose of TMP/SMX (160 mg/800 mg twice daily) for 7 to 15 days. In patients with MRSA SSTIs, those treated with the high dose of TMP/SMX (n = 121) had clinical characteristics similar to those of patients treated with the standard dose of TMP/SMX (n = 170). The only exception was a higher proportion of patients with a history of trauma upon admission among the patients treated with the higher dose. The proportion of patients with clinical resolution of infection was not different in the two groups (88/121 [73%] versus 127/170 [75%]; P = 0.79). The lack of significance remained in patients with abscess upon stratified analysis by whether surgical drainage was performed. The study found that patients with MRSA SSTIs treated with the higher dose of TMP/SMX (320/1,600 mg twice daily) for 7 to 15 days had a similar rate of clinical resolution as patients treated with the standard dose of TMP/SMX (160/800 mg twice daily) for 7 to 15 days.

AB The objective of this study was to investigate photodynamic therapy (PDT), using blue dye and red light, for prophylaxis and treatment of cutaneous Candida albicans infections in mice. A mouse model of skin abrasion infected with C. albicans was developed by inoculating wounds measuring 1.2 cm by 1.2 cm with 10(6) or 10(7) CFU. The use of a luciferase-expressing strain of C. albicans allowed real-time monitoring of the extent of infection in mice noninvasively through bioluminescence imaging. The phenothiazinium salts toluidine blue O (TBO), methylene blue (MB), and new methylene blue (NMB) were compared as photosensitizers (PS) for the photodynamic inactivation of C. albicans in vitro. PDT in vivo was initiated either at 30 min or at 24 h after fungal inoculation to investigate the efficacies of PDT for both prophylaxis and treatment of infections. Light at 635 +/- 15 nm or 660 +/- 15 nm was delivered with a light dose of 78 J/cm(2) (for PDT at 30 min postinfection) or 120 J/cm(2) (for PDT at 24 h postinfection) in multiple exposures with bioluminescence imaging taking place after each exposure of light. In vitro studies showed that NMB was superior to TBO and MB as the PS in the photodynamic inactivation of C. albicans. The efficacy of PDT was related to the ratio of PS concentration to fungal cell density. PDT in vivo initiated either at 30 min or at 24 h postinfection significantly reduced C. albicans burden in the infected mouse skin abrasion wounds. These data suggest that PDT is a viable approach for prophylaxis and treatment of cutaneous C. albicans infections.

AB Pseudomonas aeruginosa can develop resistance to polymyxin and other cationic antimicrobial peptides. Previous work has shown that mutations in the PmrAB and PhoPQ regulatory systems can confer low to moderate levels of polymyxin resistance (MICs of 8 to 64 mg/liter) in laboratory and clinical strains of this organism. To explore the role of PhoPQ in high-level clinical polymyxin resistance, P. aeruginosa strains with colistin MICs > 512 mg/liter that had been isolated from cystic fibrosis patients treated with inhaled colistin (polymyxin E) were analyzed. Probable loss-of-function phoQ alleles found in these cystic fibrosis strains conferred resistance to polymyxin. Partial and complete suppressor mutations in phoP were identified in some cystic fibrosis strains with resistance-conferring phoQ mutations, suggesting that additional loci can be involved in polymyxin resistance in P. aeruginosa. Disruption of chromosomal phoQ in the presence of an intact phoP allele stimulated 4-amino-L-arabinose addition to lipid A and induced transcription from the promoter of the pmrH (arnB) operon, consistent with the known role of this lipid A modification in polymyxin resistance. These results indicate that phoQ loss-of-function mutations can contribute to high-level polymyxin resistance in clinical strains of P. aeruginosa.

AB Plasmid-carried qnrS1 is derived from Vibrio splendidus chromosomal qnrVS1. qnrVS1 transcripts increased 21- to 34-fold with subinhibitory concentrations of ciprofloxacin but much less with mitomycin. No LexA binding sites were upstream of qnrS1 or qnrVS1, and similar induction levels were observed in lexA-positive and lexA-negative Escherichia coli strains with native qnrS1 plasmid pMG306 but not with pUC18-cloned qnrS1 or qnrVS1. Thus, qnrS1 induction by quinolones is independent of the SOS system and requires sequence besides that of the structural gene.

AB SIRT1 belongs to the silent information regulator 2 (Sir2) protein family of enzymes and functions as a NAD(+)-dependent class III histone deacetylase. Here, we examined the anti-multiple myeloma (MM) activity of a novel oral agent, SRT1720, which targets SIRT1. Treatment of MM cells with SRT1720 inhibited growth and induced apoptosis in MM cells resistant to conventional and bortezomib therapies without significantly affecting the viability of normal cells. Mechanistic studies showed that anti-MM activity of SRT1720 is associated with: (i) activation of caspase-8, caspase-9, caspase-3, poly(ADP) ribose polymerase; (ii) increase in reactive oxygen species; (iii) induction of phosphorylated ataxia telangiectasia mutated/checkpoint kinase 2 signalling; (iv) decrease in vascular endothelial growth factor-induced migration of MM cells and associated angiogenesis; and (v) inhibition of nuclear factor-kappa B. Blockade of ATM attenuated SRT1720-induced MM cell death. In animal tumour model studies, SRT1720 inhibited MM tumour growth. Finally, SRT1720 enhanced the cytotoxic activity of bortezomib or dexamethasone. Our preclinical studies provide the rationale for novel therapeutics targeting SIRT1 in MM.

AB The purpose of this study was to evaluate the survival and success of screw- versus cement-retained implant crowns over a 5-year period. This was a multi-center prospective cohort study, consisting of patients who had a parts per thousand yen1 dental implant placed and restored in the anterior maxilla over a 5-year period. The primary predictor variable was the type of restoration (screw- versus cement-retained). The outcome variables were clinician- or patient-reported measures related to soft tissue and restoration quality. Descriptive and bivariate statistics were computed to compare the screw- versus cement-retained groups. Kaplan-Meier statistics were computed for implant survival. Information was collected for 102 patients who had 214 implants placed during the study period. Complete data, amenable to analysis, were available for 99 (97.1%) patients and 193 (90.2%) implants. The restorations were approximately evenly divided between screw- (53.4%) and cement-retained (46.6%). Approximately 49% of patients in the sample were female; the sample's mean age was 47.3 +/- 13.9 years; each patient had an average of 2.0 +/- 1.0 implants placed and restored. The mean time from prosthesis placement (definitive) to study endpoint was 61.9 +/- 10.6 months. The overall implant survival rate was 96.4%, with no statistically significant difference in survival between the screw- and cement-retained groups (p = 0.45). The majority of clinician- and patient-assessed outcomes were similar. The results of this study indicate that for the majority of clinician- and patient-assessed success parameters screw- and cement-retained restorations are equivalent in the anterior maxilla.

AB Evaluation of the diagnostic performance characteristics of radiographic tests for diagnosing a true fracture among suspected scaphoid fractures is hindered by the lack of a consensus reference standard. Latent class analysis is a statistical method that takes advantage of unobserved, or latent, classes in the data that can be used to determine diagnostic performance characteristics when there is no consensus reference (gold) standard.
We therefore compared the diagnostic performance characteristics of MRI, CT, bone scintigraphy, and physical examination to identify true fractures among suspected scaphoid fractures.
We used data from two studies, one that prospectively studied 34 patients who had MRI and CT of the wrist, and a second that studied 78 patients who had MRI, bone scintigraphy, and structured physical examination. We compared the diagnostic performance characteristics calculated by latent class analysis with those calculated using formulas based on a reference standard.
In the first cohort, the calculated sensitivity and specificity with latent class analysis were different than those with traditional reference standard-based calculations for the CT in the scaphoid planes (sensitivity, 0.78 versus 0.67; specificity, 1.0 versus 0.96) and the MRI (sensitivity, 0.80 versus 0.67; specificity, 0.93 versus 0.89). In the second cohort, the greatest differences were in the sensitivity of MRI (0.84 versus 0.75) and the sensitivities of physical examination maneuvers (range, 0.63-0.73 versus 1.0).
The diagnostic performance characteristics calculated using latent class analysis may differ from those calculated according to formulas based on a reference standard. We believe latent class analysis merits further study as an option for assessing diagnostic performance characteristics for orthopaedic conditions when there is no consensus reference standard.
Level II, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.

AB Background The treatment for an early postoperative periprosthetic infection after cementless THA that results in the highest quality of life after the control of infection is unknown. Although common treatments include irrigation and d,bridement with component retention, a one-stage exchange, or a two-stage exchange, it is unclear whether any of these provides a higher quality of life after the control of infection.
Questions/purposes We projected, through decision-analysis modeling, the possible estimated final health states defined as health-related quality of life based on quality-of-life studies of an early postoperative periprosthetic infection after cementless THA treated by irrigation and d,bridement, one-stage exchange, or two-stage exchange.
Methods Publications addressing early postoperative infections after THA were analyzed for the estimated rate of infection control and quality-of-life measures after a specific treatment. Decision analysis was used to model the different treatments and describe which, if any, treatment results in the greatest quality of life after early THA infection.
Results In the model, a one-stage exchange was the treatment for early THA infection that maximized quality-of-life outcomes if the probability of controlling the infection exceeded 66% with this procedure. If the probability of infection control of a one-stage exchange was less than 66% or that of irrigation and d,bridement was greater than 60%, then irrigation and d,bridement appeared to result in the greatest quality-of-life outcome.
Conclusions A decision analysis using estimates of infection control rate and quality-of-life outcomes after different treatments for an early postoperative infection after THA showed possible outcomes for each treatment.

AB Epithelial ovarian cancer is a leading cause of cancer-related death for women both in the United States and worldwide, and the effectiveness of cytotoxic chemotherapy has plateaued. Angiogenesis plays an important role in ovarian cancer biology, and exploration of anti-angiogenic agents in this disease has demonstrated anti-tumor activity both as monotherapy and in combination with cytotoxic chemotherapy. However, key questions remain regarding the use of these drugs in ovarian cancer, such as where in treatment should they be used, should these drugs be used as single agents or combined with chemotherapy, can and which biomarkers predict efficacy, are there efficacy and toxicity differences amongst the various agents, what are the cost-benefit ratios of these therapies, and are the patient outcome improvements observed in completed studies significant enough to warrant widespread use of these drugs? Here, we review recent progress and discuss ongoing controversies regarding the use of anti-angiogenic therapies in ovarian cancer.

AB Cell differentiation is associated with changes in metabolism and function. Understanding these changes during differentiation is important in the context of stem cell research, cancer, and neurodegenerative diseases. An early event in neurodegenerative diseases is the alteration of mitochondrial function and increased oxidative stress. Studies using both undifferentiated and differentiated SH-SY5Y neuroblastoma cells have shown distinct responses to cellular stressors; however, the mechanisms remain unclear. We hypothesized that because the regulation of glycolysis and oxidative phosphorylation is modulated during cellular differentiation, this would change bioenergetic function and the response to oxidative stress. To test this, we used retinoic acid (RA) to induce differentiation of SH-SY5Y cells and assessed changes in cellular bioenergetics using extracellular flux analysis. After exposure to RA, the SH-SY5Y cells had an increased mitochondrial membrane potential, without changing mitochondria! number. Differentiated cells exhibited greater stimulation of mitochondrial respiration with uncoupling and an increased bioenergetic reserve capacity. The increased reserve capacity in the differentiated cells was suppressed by the inhibitor of glycolysis 2-deoxy-D-glucose. Furthermore, we found that differentiated cells were substantially more resistant to cytotoxicity and mitochondrial dysfunction induced by the reactive lipid species 4-hydroxynonenal or the reactive oxygen species generator 2,3-dimethoxy-1,4-naphthoquinone. We then analyzed the levels of selected mitochondrial proteins and found an increase in complex IV subunits, which we propose contributes to the increase in reserve capacity in the differentiated cells. Furthermore, we found an increase in MnSOD that could, at least in part, account for the increased resistance to oxidative stress. Our findings suggest that profound changes in mitochondrial metabolism and antioxidant defenses occur upon differentiation of neuroblastoma cells to a neuron-like phenotype. (C) 2011 Elsevier Inc.

AB Primary open-angle glaucoma (POAG) is a genetically complex common disease characterized by progressive optic nerve degeneration that results in irreversible blindness. Recently, a genome-wide association study (GWAS) for POAG in an Icelandic population identified significant associations with single nucleotide polymorphisms (SNPs) between the CAV1 and CAV2 genes on chromosome 7q31. In this study, we confirm that the identified SNPs are associated with POAG in our Caucasian US population and that specific haplotypes located in the CAV1/CAV2 intergenic region are associated with the disease. We also present data suggesting that associations with several CAV1/CAV2 SNPs are significant mostly in women.

AB Mutations in the BRCA1 gene substantially increase a woman's lifetime risk of breast cancer. However, there is great variation in this increase in risk with several genetic and non-genetic modifiers identified. The BRCA1 protein plays a central role in DNA repair, a mechanism that is particularly instrumental in safeguarding cells against tumorigenesis. We hypothesized that polymorphisms that alter the expression and/or function of BRCA1 carried on the wild-type (non-mutated) copy of the BRCA1 gene would modify the risk of breast cancer in carriers of BRCA1 mutations. A total of 9874 BRCA1 mutation carriers were available in the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA) for haplotype analyses of BRCA1. Women carrying the rare allele of single nucleotide polymorphism rs16942 on the wild-type copy of BRCA1 were at decreased risk of breast cancer (hazard ratio 0.86, 95% confidence interval 0.77-0.95, P = 0.003). Promoter in vitro assays of the major BRCA1 haplotypes showed that common polymorphisms in the regulatory region alter its activity and that this effect may be attributed to the differential binding affinity of nuclear proteins. In conclusion, variants on the wild-type copy of BRCA1 modify risk of breast cancer among carriers of BRCA1 mutations, possibly by altering the efficiency of BRCA1 transcription.

AB While our understanding of the pathogenesis and management of acute respiratory distress syndrome (ARDS) has improved over the past decade, estimates of its incidence have been controversial. The goal of this study was to examine ARDS incidence and outcome under current lung protective ventilatory support practices before and after the diagnosis of ARDS.
This was a 1-year prospective, multicenter, observational study in 13 geographical areas of Spain (serving a population of 3.55 million at least 18 years of age) between November 2008 and October 2009. Subjects comprised all consecutive patients meeting American-European Consensus Criteria for ARDS. Data on ventilatory management, gas exchange, hemodynamics, and organ dysfunction were collected.
A total of 255 mechanically ventilated patients fulfilled the ARDS definition, representing an incidence of 7.2/100,000 population/year. Pneumonia and sepsis were the most common causes of ARDS. At the time of meeting ARDS criteria, mean PaO2/FiO(2) was 114 +/- A 40 mmHg, mean tidal volume was 7.2 +/- A 1.1 ml/kg predicted body weight, mean plateau pressure was 26 +/- A 5 cmH(2)O, and mean positive end-expiratory pressure (PEEP) was 9.3 +/- A 2.4 cmH(2)O. Overall ARDS intensive care unit (ICU) and hospital mortality was 42.7% (95%CI 37.7-47.8) and 47.8% (95%CI 42.8-53.0), respectively.
This is the first study to prospectively estimate the ARDS incidence during the routine application of lung protective ventilation. Our findings support previous estimates in Europe and are an order of magnitude lower than those reported in the USA and Australia. Despite use of lung protective ventilation, overall ICU and hospital mortality of ARDS patients is still higher than 40%.

AB To determine the effectiveness of a provider-based education and implementation intervention for improving diabetes control.
Cluster-randomized trial with baseline and follow-up cross sections of diabetes patients in each participating physicians practice.
Eleven US Southeastern states, 200608.
Two hundred and five rural primary care physicians.
Multi-component interactive intervention including Web-based continuing medical education, performance feedback and quality improvement tools.
oAcceptable control' [hemoglobin A1c 9, blood pressure (BP) 140/90 mmHg, low-density lipoprotein cholesterol (LDL) 130 mg/dl] and ooptimal control' (A1c 7, BP 130/80 mmHg, LDL 100 mg/dl).
Of 364 physicians attempting to register, 205 were randomized to the intervention (n 102) or control arms (n 103). Baseline and follow-up data were provided by 95 physicians (2127 patients). The proportion of patients with A1c 9 was similar at baseline and follow-up in both the control [adjusted odds ratio (AOR): 0.94; 95 confidence interval (CI): 0.61, 1.47] and intervention arms [AOR: 1.16 (95 CI: 0.80, 1.69)]; BP 140/90 mmHg and LDL 130 mg/dl were also similar at both measurement points (P 0.66, P 0.46; respectively). We observed no significant effect on diabetes control attributable to the intervention for any of the primary outcome measures. Intervention physicians engaged with the Website over a median of 64.7 weeks [interquartile range (IQR): 45.481.8) for a median total of 37 min (IQR: 1666).
A wide-reach, low-intensity, Web-based interactive multi-component intervention did not improve control of glucose, BP or lipids for patients with diabetes of physicians practicing in the rural Southeastern US.

AB In their article, "Measurement of cochlear power gain in the sensitive gerbil ear," Ren et al. (Nat Commun 2:216, 2011) claim to provide "the first direct experimental evidence of power amplification in the sensitive living cochlea." While we recognize the technical challenges of the experiments and appreciate the beauty of the data, the authors' analysis and interpretation of the measurements are invalid. We review the concept of impedance (i.e., the ratio of pressure to velocity) as it applies to cochlear mechanics and show that Ren et al. mistakenly equate the impedances near the basilar membrane and stapes with the impedance characteristic of an infinite, uniform tube of fluid. As a consequence of this error, Ren et al.'s measurements and analysis provide no evidence for power amplification in the cochlea. Compelling evidence for power amplification has, however, been previously provided by others.

AB In cases of acquired sensorineural hearing loss, death of cochlear neurons is thought to arise largely as a result of sensory-cell loss. However, recent studies of acoustic overexposure report massive degeneration of the cochlear nerve despite complete hair cell survival (Kujawa and Liberman, J Neurosci 29:14077-14085, 2009). To assess the primary loss of spiral ganglion cells (SGCs) in human ears, neuronal counts were performed in 100 temporal bones from 100 individuals, aged newborn to 100 years, selected to include only cases with a normal population of inner and outer hair cells. Ganglion cell counts declined at a mean rate of 100 cells per year of life. There were no significant gender or inter-aural differences, and a slight increase in degeneration in the basal turn re upper turns was not statistically significant. The age-related decline in SGCs was significantly less than that in prior studies that included ears with hair cell loss (Otte et al., Laryngoscope 88:1231-1246, 1978), but significantly more than for analogous data on vestibular ganglion cells in cases without vestibular hair cell loss (Velazquez-Villasenor et al., Ann Otol Rhinol Laryngol Suppl 181:14-19, 2000). The age-related decline in SGC counts may contribute to the well-known decline in hearing-in-noise performance, and the data will help in interpretation of histopathological findings from temporal bones with known otologic disease.

AB Background. Children spend a significant amount of time in school. Little is known about the role of allergen exposure in school environments and asthma morbidity. Objectives. The School Inner-City Asthma Study (SICAS) is a National Institutes of Health (NIH)-funded prospective study evaluating the school/classroom-specific risk factors and asthma morbidity among urban children. Methods/results. This article describes the design, methods, and important lessons learned from this extensive investigation. A single center is recruiting 500 elementary school-aged children, all of whom attend inner-city metropolitan schools. The primary hypothesis is that exposure to common indoor allergens in the classroom will increase the risk of asthma morbidity in children with asthma, even after controlling for home allergen exposures. The protocol includes screening surveys of entire schools and baseline eligibility assessments obtained in the spring prior to the academic year. Extensive baseline clinical visits are being conducted among eligible children with asthma during the summer prior to the academic school year. Environmental classroom/school assessments including settled dust and air sampling for allergen, mold, air pollution, and inspection data are collected twice during the academic school year and one home dust sample linked to the enrolled student. Clinical outcomes are measured every 3 months during the academic school year. Conclusion. The overall goal of SICAS is to complete the first study of its kind to better understand school-specific urban environmental factors on childhood asthma morbidity. We also discuss the unique challenges related to school-based urban research and lessons being learned from recruiting such a cohort.

AB Androgen deprivation therapy (ADT) for prostate cancer increases fracture risk, decreases bone mineral density, and increases bone turnover markers (BTMs) including serum type 1 C-telopeptide (sCTX), tartrate-resistant alkaline phosphatase 5b (TRAP-5b), and procollagen-1 N-terminal telopeptide (P1NP). In a prespecified exploratory analysis of a phase 3, multicenter, double-blind study, we evaluated the effects of denosumab (60 mg subcutaneously every 6 months for 3 years) versus placebo (1468 patients, 734 in each group) on BTM values. BTMs were measured at baseline, month 1, and predose at months 6, 12, 24, and 36 in the overall population. BTMs at month 1 are also reported for subgroups based on age (< 70 years versus >= 70 years), prior duration of ADT (<= 6 months versus >6 months), and baseline BTM (<= median versus > median BTM values). Treatment with denosumab provided a rapid and sustained decrease of BTM values compared with placebo. The median change in sCTX levels at month 1 was -90% in the denosumab group and -3% in the placebo group (p < 0.0001). The median change in TRAP-5b levels at month 1 was -55% in the denosumab group and -3% in the placebo group (p < 0.0001). The maximal median change in P1NP was -64% in the denosumab group and -11% in the placebo group, (p < 0.0001). Significantly greater decreases in BTM for denosumab were also seen in subgroup analyses based on age, prior ADT treatment, and baseline BTM values. Suppression of bone turnover markers was consistent with marked increases in bone mineral density reported previously. (C) 2011 American Society for Bone and Mineral Research.

AB The extracellular Ca2+-sensing receptor (CaR), a G protein-coupled receptor responsible for maintenance of calcium homeostasis, is implicated in regulation of skeletal metabolism. To discern the role of the osteoblast CaR in regulation of bone development and remodeling, we generated mice in which the CaR is excised in a broad population of osteoblasts expressing the 3.6-kb a(1)(I) collagen promoter. Conditional knockouts had abnormal skeletal histology at birth and developed progressively reduced mineralization secondary to retarded osteoblast differentiation, evident by significantly reduced numbers of osteoblasts and decreased expression of collagen I, osteocalcin, and sclerostin mRNAs. Elevated expression of ankylosis protein, ectonucleotide pyrophosphatase/phospho-diesterase 1, and osteopontin mRNAs in the conditional knockout indicate altered regulation of genes important in mineralization. Knockout of the osteoblast CaR also resulted in increased expression of the receptor activator of NF-kappa B ligand (RANKL), the major stimulator of osteoclast differentiation and function, consistent with elevated osteoclast numbers in vivo. Osteoblasts from the conditional knockouts exhibited delayed differentiation, reduced mineralizing capacity, altered expression of regulators of mineralization, and increased ability to promote osteoclastogenesis in coculture experiments. We conclude that CaR signaling in a broad population of osteoblasts is essential for bone development and remodeling and plays an important role in the regulation of differentiation and expression of regulators of bone resorption and mineralization.

AB Youth in urban environments are exposed to community violence, yet some do well and continue on a positive developmental trajectory. This study investigated the relationships between lifetime community violence exposure (including total, hearing about, witnessing, and victimization), family functioning, and positive youth development (PYD) among 110 urban youth ages 10-16 years (54% female) using a paper and pen self-report survey. This cross-sectional study was part of an interdisciplinary community-based participatory research effort in West/Southwest Philadelphia. Almost 97% of the sample reported some type of community violence exposure. Controlling for presence of mother in the home and presence of father in the home, separate linear regression models for PYD by each type of community violence exposure indicated that gender and family functioning were significantly associated with PYD. None of the types of community violence exposure were significant in the models. Significant interactions between gender and presence of mother in the home and gender and family functioning helped better explain these relationships for some of the types of community violence exposure. Presence of mother was associated with higher PYD for girls, but not for boys. Boys with poor family functioning had lower PYD than girls with poor family functioning. This study helps to better delineate relationships between CVE and PYD by adding new knowledge to the literature on the role of family functioning. Points of intervention should focus on families, with attention to parental figures in the home and overall family functioning.

AB Objectives To evaluate the prevalence and factors affecting the detection of active brown adipose tissue (BAT) in children and adolescents using 18 F-fluorodeoxyglucose positron emission tomography.
Study design A total of 385 positron emission tomography scans performed for various oncologic indications in 172 patients aged 5-21 years were reviewed. BAT activity was detected by visual inspection as present or absent in the neck, thorax, and abdomen based on its well-characterized and typical appearance and then quantified by comparing the 18 F-fluorodeoxyglucose activity in the cervical-supraclavicular depots with that measured in the liver. Clinical indices were recorded.
Results The BAT detection rate was not significantly different between boys and girls (43.3% vs 45.3%). BAT activity was found most often in the cervical-supraclavicular depots. The highest percentage of patients with detectable BAT and the highest BAT/liver activity were in the 13-to 14.99-year age group in both males and females (P = .005). Body mass index percentile correlated inversely with BAT activity (P = .012). BAT activity did not correlate with outdoor temperature or clinical diagnosis.
Conclusion Under typical clinical imaging conditions, BAT is detected more frequently in children than in adults. BAT activity increases from childhood into adolescence, when it is detected in almost half of patients, and it correlates inversely with obesity, suggesting that BAT may play a prominent role in pediatric metabolism.

SO JOURNAL OF SURGICAL RESEARCH

DE surgical ethics; resident education; clinical ethics
ID EDUCATION; FUTURE
AB Background. PGY-1 year of surgical residency brings together many persons of disparate experiences and educational backgrounds, including their exposure to ethics. We hypothesized that surgical PGY-1s would have a similar exposure to ethical scenarios but lack the confidence in practice and understanding of ethical principles compared with more senior residents.
Materials and Methods. Surgical residents were invited to resident-initiated surgical ethics workshops utilizing a standardized text. Here a survey and multiple choice tests were administered to participants. The survey determined prior exposure to ethics curricula, the frequency of exposure to various ethics topics, and their comfort with these scenarios. A multiple choice test then quantified the knowledge base of participating residents. The results were collected and compared between surgical PGY-1s and more senior residents.
Results. Eighteen PGY-1s and 12 senior residents completed this curriculum. Resident exposure to ethical concepts was common. Resident confidence in these topics was ranked moderate or higher for both groups. Despite frequent clinical exposure and strong confidence in their skills of addressing these topics, performance on the test was poor, with an average score of 59% for PGY-1s and 47% for more senior residents (P = 0.03).
Conclusions. Despite clinical exposure to and confidence in their management of ethical topics, their knowledge base was poor and worse for more senior residents. Given the overall interest in a formal ethics curriculum and the knowledge deficit demonstrated, educational intervention and professional ethics support should be provided for surgical residents even with the current educational time constraints.

AB Intact ribosomal RNAs (rRNAs) comprise the majority of somatic transcripts, yet appear conspicuously absent in spermatozoa, perhaps reflecting cytoplasmic expulsion during spermatogenesis. To discern their fate, total RNA retained in mature spermatozoa from three fertile donors was characterized by Next Generation Sequencing. In all samples, >75% of total sequence reads aligned to rRNAs. The distribution of reads along the length of these transcripts exhibited a high degree of non-uniformity that was reiterated between donors. The coverage of sequencing reads was inversely correlated with guanine-cytosine (GC)-richness such that sequences greater than similar to 70% GC were virtually absent in all sperm RNA samples. To confirm the loss of sequence, the relative abundance of specific regions of the 28S transcripts in sperm was established by 7-Deaza-2'-deoxy-guanosine-5'-triphosphate RT-PCR. The inability to amplify specific regions of the 28S sequence from sperm despite the abundant representation of this transcript in the sequencing libraries demonstrates that approximately three-quarters of RNA retained in the mature male gamete are products of rRNA fragmentation. Hence, cleavage (not expulsion of the RNA component of the translational machinery) is responsible for preventing spurious translation following spermiogenesis. These results highlight the potential importance of those transcripts, including many mRNAs, which evade fragmentation and remain intact when sperm are delivered at fertilization. Sequencing data are deposited in GEO as: GSE29160.

AB Dendritic cells (DCs), which are known to support immune activation during infection, may also regulate immune homeostasis in resting animals. Here we show that mice lacking the ubiquitin-editing molecule A20 specifically in DCs spontaneously showed DC activation and population expansion of activated T cells. Analysis of DC-specific epistasis in compound mice lacking both A20 and the signaling adaptor MyD88 specifically in DCs showed that A20 restricted both MyD88-independent signals, which drive activation of DCs and T cells, and MyD88-dependent signals, which drive population expansion of T cells. In addition, mice lacking A20 specifically in DCs spontaneously developed lymphocyte-dependent colitis, seronegative ankylosing arthritis and enthesitis, conditions stereotypical of human inflammatory bowel disease (IBD). Our findings indicate that DCs need A20 to preserve immune quiescence and suggest that A20-dependent DC functions may underlie IBD and IBD-associated arthritides.

AB Making an accurate diagnosis of schizophrenia and related psychoses early in the course of the disease is important for initiating treatment and counseling patients and families. In this study, we developed classification models for early disease diagnosis using structural MRI (sMRI) and neuropsychological (NP) testing. We used sMRI measurements and NP test results from 28 patients with recent-onset schizophrenia and 47 healthy subjects, drawn from the larger sample of the Mind Clinical Imaging Consortium. We developed diagnostic models based on Linear Discriminant Analysis (LDA) following two approaches; namely, (a) stepwise (STP) LDA on the original measurements, and (b) LDA on variables created through Principal Component Analysis (PCA) and selected using the Humphrey-Ilgen parallel analysis. Error estimation of the modeling algorithms was evaluated by leave-one-out external cross-validation. These analyses were performed on sMRI and NP variables separately and in combination. The following classification accuracy was obtained for different variables and modeling algorithms. sMRI only: (a) STP-LDA: 64.3% sensitivity and 76.6% specificity, (b) PCA-LDA: 67.9% sensitivity and 72.3% specificity. NP only: (a) STP-LDA: 71.4% sensitivity and 80.9% specificity, (b) PCA-LDA: 78.5% sensitivity and 91.5% specificity. Combined sMRI-NP: (a) STP-LDA: 64.3% sensitivity and 83.0% specificity, (b) PCA-LDA: 89.3% sensitivity and 93.6% specificity. (i) Maximal diagnostic accuracy was achieved by combining sMRI and NP variables. (ii) NP variables were more informative than sMRI, indicating that cognitive deficits can be detected earlier than volumetric structural abnormalities. (iii) PCA-LDA yielded more accurate classification than STP-LDA. As these sMRI and NP tests are widely available, they can increase accuracy of early intervention strategies and possibly be used in evaluating treatment response.

AB Primary vertebral tumors, although less common than metastases to the spine, make up a heterogeneous group of neoplasms that can pose diagnostic and treatment challenges. They affect both the adult and the pediatric population and may be benign, locally aggressive, or malignant. An understanding of typical imaging findings will aid in accurate diagnosis and help neurosurgeons appreciate anatomic subtleties that may increase their effective resection. An understanding of the histological similarities and differences between these tumors is imperative for all members of the clinical team caring for these patients. In this first review of 2 parts, we discuss the epidemiological, histological, and imaging features of the most common benign primary vertebral tumors-aneurysmal bone cyst, chondroma and enchondroma, hemangioma, osteoid osteoma, and osteoblastoma-and lesions related to eosinophilic granuloma and fibrous dysplasia. In addition, we discuss the basic management paradigms for each of these diagnoses. In combination with part II of the review, which focuses on locally aggressive and malignant tumors, this article provides a comprehensive review of primary vertebral tumors.

AB BACKGROUND: Recent interest has demonstrated the nucleus accumbens (NAcc) as a potential target for the treatment of depression with deep brain stimulation (DBS).
OBJECTIVE: To demonstrate that DBS of the NAcc is an effective treatment modality for depression and that chemical and structural changes associated with these behavioral changes are markers of neuroplasticity.
METHODS: A deep brain stimulator was placed in the NAcc of male Wistar-Kyoto rats. Groups were divided into sham (no stimulation), intermittent (3 h/d for 2 weeks), or continuous (constant stimulation for 2 weeks). Exploratory and anxietylike behaviors were evaluated with the open-field test before and after stimulation. Tissue samples of the prefrontal cortex (PFC) were processed with Western blot analysis of markers of noradrenergic activity that included the noradrenergic synthesizing enzyme tyrosine hydroxylase. Analysis of tissue levels for catecholamines was achieved with high-performance liquid chromatography. Morphological properties of cortical pyramidal neurons were assessed with Golgi-Cox staining.
RESULTS: Subjects undergoing intermittent and continuous stimulation of the NAcc exhibited an increase in exploratory behavior and reduced anxietylike behaviors. Tyrosine hydroxylase expression levels were decreased in the PFC after intermittent and continuous DBS, and dopamine and norepinephrine levels were decreased after continuous stimulation. Golgi-Cox staining indicated that DBS increased the length of apical and basilar dendrites in pyramidal neurons of the PFC.
CONCLUSION: Deep brain stimulation induces behavioral improvement in and neurochemical and morphological alterations of the PFC that demonstrate changes within the circuitry of the brain different from the target area of stimulation. This observed dendritic plasticity may underlie the therapeutic efficacy of this treatment.

AB One of the most prevalent workplace chemical exposures historically and currently confronting the global military and civilian workforce is jet propellant (JP) fuel (e.g., JP4, JP5, JP8, jet A1), a complex mixture of numerous hydrocarbon compounds and additives. To date, numerous protective and preventive strategies (e.g., federal exposure limits, workplace procedure protocols, protective gear such as goggles, respirator use, gloves, and coveralls) have been put in place to minimize acutely toxic exposure levels. However, questions remain regarding the effect of repeated exposures at lower (than regulated) levels of JP fuel. The Occupational JP8 Exposure Neuroepidemiology Study (OJENES) was designed to examine the relationships between occupational JP8 exposure over multiple, repeated workdays and specific aspects of central nervous system (CNS) functioning among Air Force (AF) personnel. In this report, we present the OJENES methodology, descriptive findings related to participant characteristics, JP8 exposure levels observed over a work week among higher and lower exposure groups, and neuropsychological task performances at the first study assessment. Results indicated minimal differences between participants in the high and lower exposure groups in terms of descriptive characteristics, other than daily JP8 exposure levels (p < 0.001). In addition, neuropsychological task performances for most task measures were not found to be significantly different from reported reference ranges. These findings demonstrated that confounding and misclassification of exposure and outcome status are not major concerns for the study. Therefore, future OJENES analyses targeting the more focused research questions regarding associations between JP8 exposure and CNS functioning are likely to provide valid conclusions, as they will be less influenced by these research biases.

AB Background: More than 100,000 US troops were potentially exposed to chemical warfare agents sarin (GB) and cyclosarin (GF) when an ammunition dump at Khamisiyah, Iraq was destroyed during the 1991 Persian Gulf War (GW). We previously found reduced total gray matter (GM) volume in 40 GW veterans with suspected GB/GF exposure relative to 40 matched, unexposed GW veterans on a 1.5 T MR scanner. In this study, we reexamine the relationship between GB/GF exposure and volumetric measurements of gross neuroanatomical structures in a different cohort of GW veterans on a 4 T MR scanner.
Methods: Neuropsychological and magnetic resonance imaging (MRI) data from a cross sectional study on Gulf War Illness performed between 2005 and 2010 were used in this study. 4T MRI data were analyzed using automated image processing techniques that produced volumetric measurements of gray matter (GM), white matter (WM) and cerebrospinal fluid (CSF).
Results: Binary comparisons of 64 GB/GF exposed veterans and 64 'matched', unexposed veterans revealed reduced GM (p = 0.03) and WM (p = 0.03) volumes in the exposed veterans. Behaviorally, exposed veterans committed more errors of omission (p = 0.02) and tended to have slower responses (p = 0.05) than unexposed veterans on the Continuous Performance Test (CPT), a measure sustained and selective attention. Regression analyses confirmed that GB/GF exposure status predicted GM (beta = -0.11, p = 0.02) and WM (beta = -0.14, p = 0.03) volumes, and number of CPT omission errors (beta = 0.22, p = 0.02) over and above potentially confounding demographic, clinical, and psychosocial variables. There was no dose-response relationship between estimated levels of GB/GF exposure and brain volume. However, we did find an effect of Gulf War Illness/Chronic Mulitsymptom Illness on both GM and WM volume in the GB/GF exposed veterans.
Conclusions: These findings confirm previous reports by our group and others of central nervous system pathology in GW veterans with suspected exposure to low levels of GB/GF two decades after the exposure. (C) 2011 Elsevier Inc. All rights reserved.

AB Background: The stress-inducible immediate early response gene X-1 (IEX-1) regulates cell proliferation and apoptosis in a cell type and stimulus-dependent manner. The aim of this study was to investigate IEX-1 expression and its role in apoptosis of ovarian epithelial tumors for potential use in clinical diagnosis and therapy.
Methods: IEX-1 expression was examined in paraffin-embedded specimens from 77 patients with epithelial ovarian tumors using immunohistochemistry. Correlation between IEX-1 expression and other clinicopathological parameters was evaluated. Apoptosis of tumor cells was detected by terminal deoxynucleotide transferase-mediated dUTP nick end labeling (TUNEL).
Results: IEX-1 expression was significantly lower in ovarian cancers compared to cystadenomas and borderline tumors (p < .05). The expression was significantly associated with FIGO stage and histological grade (p < .05), but not with age, histological type, or residual tumor (p > .05). A positive correlation was also observed between IEX-1 expression and apoptotic index (p < .01) or survival (p = .005).
Conclusion: With the development of epithelial ovarian tumors from benign to malignant, IEX-1 expression is decreased, concomitant with a decreased rate of cell apoptosis. Thus, IEX-1 is pro-apoptotic in the development of epithelial ovarian cancer. The pro-apoptotic activity may take part in restraining tumor growth at the early stage of ovarian epithelial cancer, whereas its decreased expression probably contributes to the abnormal survival advantage for malignant cancer. Altered IEX-1 expression can potentially be a new predictor of the malignant transformation and a prognostic indicator for cancer therapy.

AB A topological multiple testing scheme for one-dimensional domains is proposed where, rather than testing every spatial or temporal location for the presence of a signal, tests are performed only at the local maxima of the smoothed observed sequence. Assuming unimodal true peaks with finite support and Gaussian stationary ergodic noise, it is shown that the algorithm with Bonferroni or Benjamini-Hochberg correction provides asymptotic strong control of the family wise error rate and false discovery rate, and is power consistent, as the search space and the signal strength get large, where the search space may grow exponentially faster than the signal strength. Simulations show that error levels are maintained for nonasymptotic conditions, and that power is maximized when the smoothing kernel is close in shape and bandwidth to the signal peaks, akin to the matched filter theorem in signal processing. The methods are illustrated in an analysis of electrical recordings of neuronal cell activity.

AB Several directly acting and host targeting antivirals that inhibit hepatitis C virus replication have entered clinical trials. Among the most advanced of these are RG7128, an inhibitor of the NS5B polymerase; BMS-790052, an inhibitor of NS5A; and alisporivir, an inhibitor of human cyclophilins. These agents have potent antiviral activity in chronic HCV patients, act additively or synergistically with inhibitors of the HCV NS3/4A protease, and improve the rate of virologic response produced by traditional pegylated interferon plus ribavirin therapy. No cross resistance has been observed; moreover, nucleoside NS5B and cyclophilin inhibitors appear to suppress resistance to non-nucleoside NS5B and NS3/4A inhibitors. Several recent reports of virologic responses produced by combinations of agents that inhibit HCV replication in the absence of interferon provide optimism that eradication of HCV will be possible without interferon in the future.

AB The rapidly emerging disorder now known as IgG(4)-related disease (IgG(4)-RD) includes a variety of clinical entities once regarded as being entirely separate diseases. Manifestations of IgG(4)-RD have now been reported in essentially all organ systems. Regardless of which organ is involved, tissue biopsies reveal striking histopathological similarities. The hallmark pathology findings are diffuse lymphoplasmacytic infiltrates, abundant IgG(4)-positive plasma cells, modest tissue eosinophilia, and extensive fibrosis. Tumorous swelling and obliterative phlebitis are other frequently observed features. Polyclonal elevations of serum IgG(4) are found in approximately 70% of patients. Many questions pertaining to the etiology, pathophysiology, epidemiology, clinical features, therapy, disease monitoring, and long-term outcomes remain to be addressed. This paper focuses on the clinical and pathological features of IgG(4)-RD.

DT Article
AB Because of the central role of platelets in cardiovascular atherothrombosis, there is a well-established therapeutic role for antiplatelet therapy that includes aspirin (a cyclooxygenase 1 [COX1] inhibitor), clopidogrel (an antagonist of the ADP P2Y(12) receptor), and the GPIIb-GPIIIa (alpha IIb beta 3) antagonists. However, there remains a significant incidence of arterial thrombosis in patients treated with currently available antiplatelet therapy. Novel P2Y(12) antagonists such as the recently US Food and Drug Administration (FDA)-approved prasugrel, along with ticagrelor, cangrelor, and elinogrel, have advantages over clopidogrel, including more rapid, less variable, and more complete inhibition of platelet function. Currently ongoing phase 3 studies will determine whether these new P2Y(12) antagonists will result in better and/or more rapid antithrombotic effects than clopidogrel, without an unacceptable increase in hemorrhagic or other side effects, as has been recently reported in some clinical settings for prasugrel and ticagrelor. Antagonists of the thrombin receptor protease-activated receptor 1 (PAR1) are also undergoing phase 3 trials, and many other novel antiplatelet agents are under investigation as antithrombotic agents.

TI Diagnosis and Management of Aplastic Anemia
SO HEMATOLOGY-AMERICAN SOCIETY HEMATOLOGY EDUCATION PROGRAM
LA English
DT Article
AB Aplastic anemia remains a diagnosis of exclusion. Our ability to reliably diagnose, and therefore exclude, a variety of inherited or acquired diseases with similar phenotypes has improved markedly. An efficient diagnostic plan is important because time from diagnosis to treatment is related to outcome regardless of the therapeutic option chosen. HSCT remains the mainstay of therapy for those with matched sibling donors, and results have improved even further in recent years. For those without a sibling donor, the high response and overall survival rates of combined immunosuppressive therapy (IST) have proven robust. Nonetheless, incomplete response, relapse, and progression to myelodysplasia/leukemia have more clearly emerged as significant long-term issues. Improvements in outcome of alternative donor transplantation and the use of established and novel immunosuppressive agents provide multiple alternatives for treating refractory or relapsed patients. Best practices in this regard are not yet clearly established and may vary by a variety of demographic and treatment-specific factors. Regardless of the type of therapeutic approach, patients require ongoing monitoring for occurrence of disease and/or therapy-related side effects.

AB Patient outcome in multiple myeloma (MM) has been remarkably improved due to the use of combination therapies including proteasome inhibitors and immunomodulatory drugs, which target the tumor in its BM microenvironment. Ongoing efforts to improve the treatment paradigm even further include using oncogenomics to better characterize molecular pathogenesis and to develop refined patient stratification and personalized medicine in MM; using models of MM in its BM milieu to identify novel targets and to validate next-generation therapeutics directed at these targets; developing immune-based therapies including mAbs, immunotoxins targeting MM cells and cytokines, and novel vaccine strategies; and using functional oncogenomics to inform the design of novel combination therapies. With continued rapid evolution of progress in these areas, MM will be a chronic illness with sustained complete response in a significant number of patients.

TI Targeting Epigenetic Programs in MLL-Rearranged Leukemias
SO HEMATOLOGY-AMERICAN SOCIETY HEMATOLOGY EDUCATION PROGRAM
LA English
DT Article
AB Rearrangements of the Mixed-Lineage Leukemia (MLL) gene are found in > 70% of infant leukemia, similar to 10% of adult acute myelogenous leukemia (AML), and many cases of secondary acute leukemias. The presence of an MLL rearrangement generally confers a poor prognosis. There are more than 60 known fusion partners of MLL having some correlation with disease phenotype and prognosis. The most common fusion proteins induce the inappropriate expression of homeotic (Hox) genes, which, during normal hematopoiesis, are maintained by wild-type MLL. MLL-rearranged leukemias display remarkable genomic stability, with very few gains or losses of chromosomal regions. This may be explained by recent studies suggesting that MLL-rearranged leukemias are largely driven by epigenetic dysregulation. Several epigenetic regulators that modify DNA or histones have been implicated in MLL-fusion driven leukemogenesis, including DNA methylation, histone acetylation, and histone methylation. The histone methyltransferase DOT1L has emerged as an important mediator of MLL-fusion-mediated leukemic transformation. The clinical development of targeted inhibitors of these epigenetic regulators may therefore hold promise for the treatment of MLL-rearranged leukemia.

AB Despite the widespread use of highly effective chemoimmunotherapy (CIT), fludarabine-refractory chronic lymphocytic leukemia (CLL) remains a challenging clinical problem associated with poor overall survival (OS). The traditional definition, which includes those patients with no response or relapse within 6 months of fludarabine, is evolving with the recognition that even patients with longer remissions of up to several years after CIT have poor subsequent treatment response and survival. Approved therapeutic options for these patients remain limited, and the goal of therapy for physically fit patients is often to achieve adequate cytoreduction to proceed to allogeneic stem cell transplantation (alloSCT). Fortunately, several novel targeted therapeutics in clinical trials hold promise of significant benefit for this patient population. This review discusses the activity of available and novel therapeutics in fludarabine-refractory or fludarabine-resistant CLL as well as recently updated data on alloSCT in CLL.

AB Rupture of the anterior cruciate ligament (ACL) is one of the most common sports-related injuries. However, with its poor healing capacity, surgical reconstruction is currently required to restore its function. Due to serious complications associated with these reconstructions, the use of tissue engineering as an alternative has grown in appeal. Engineering approaches using ligament-derived fibroblasts have been promising but their slow growth rate may limit their practical application. More promising results have been being achieved using stem cells, in combination with appropriate growth factors. As a growth factor, GDF-5 has been shown to play a role in ligament and tendon formation, while bone marrow stem cells have shown promise in their repair. Combining these two parameters, previous work by our group has shown that a combination of GDF-5 and bone marrow stem cells in a 3D environment results in increased expression of several ligament tissue markers. In this study, we continue this work to explore if a dose-response relationship exists between GDF-5 and the stem cell. For this, murine bone marrow stem cells (D1 cells) were exposed to increasing doses of GDF-5 in a standard monolayer culture system and the expression of several ligament genes quantified. In contrast to our previous 3D system, exposing D1 cells to increasing doses of GDF-5 in a 2D culture system did not significantly affect the expression of these markers. Therefore, a more appropriate system for determining the effect of growth factors on stem cells may be a 3D culture system.

TI Creating an Oversight Infrastructure for Electronic Health
Record-Related Patient Safety Hazards
SO JOURNAL OF PATIENT SAFETY
LA English
DT Article
DE electronic health record; patient safety; surveillance
AB Electronic health records (EHRs) have potential quality and safety benefits. However, reports of EHR-related safety hazards are now emerging. The Office of the National Coordinator for Health Information Technology recently sponsored an Institute of Medicine committee to evaluate how health information technology use affects patient safety. In this article, we propose the creation of a national EHR oversight program to provide dedicated surveillance of EHR-related safety hazards and to promote learning from identified errors, close calls, and adverse events. The program calls for data gathering, investigation/analysis, and regulatory components. The first 2 functions will depend on institution-level EHR safety committees that will investigate all known EHR-related adverse events and near-misses and report them nationally using standardized methods. These committees should also perform routine safety self-assessments to proactively identify new risks. Nationally, we propose the long-term creation of a centralized, nonpartisan board with an appropriate legal and regulatory infrastructure to ensure the safety of EHRs. We discuss the rationale of the proposed oversight program and its potential organizational components and functions. These include mechanisms for robust data collection and analyses of all safety concerns using multiple methods that extend beyond reporting, multidisciplinary investigation of selected high-risk safety events, and enhanced coordination with other national agencies to facilitate broad dissemination of hazards information. Implementation of this proposed infrastructure can facilitate identification of EHR-related adverse events and errors and potentially create a safer and more effective EHR-based health care delivery system.

SO MINERALS
LA English
DT Article
DE artisanal small-scale gold mining; human biomonitoring; mercury vapor
AB Objectives: In artisanal small-scale gold mining (ASGM) areas in many developing countries, mercury (Hg) is used to extract gold from ore. Data of 1250 participants from Indonesia, Mongolia, Philippines, Tanzania, and Zimbabwe were combined to analyze the relation between exposure in ASGM areas and body burden. Methods: Four groups were selected relating to their intensity of contact with mercury: (i) a non-exposed control group; (ii) a low exposed group with participants only living in mining areas, but not working as miners; (iii) a medium exposed group, miners living in exposed areas and working with mercury without smelting amalgam; and (iv) a high exposed group, miners living in exposed areas and smelting amalgam. Results: Compared to the non-exposed control group, participants living and/or miners working in highly exposed areas have significantly higher concentration of total mercury in urine, hair and blood (p-value < 0.001). The median mercury value in urine in the control group is < 0.2 mu g/L. In the high exposed group of amalgam smelters, the median in urine is 12.0 mu g/L. The median in blood in the control group is < 0.93 mu g/L. The median level in blood of the high exposed group is 7.56 mu g/L. The median for mercury in hair samples from the control group is 0.21 mu g/g. In the high exposed group the median hair concentration is 2.4 mu g/g hair. Mercury levels also differ considerably between the countries, reflecting a diverse background burden due to different fish eating habits and different work place methods. Conclusions: A high percentage of exposed individuals had levels above threshold values. These high levels of mercury are likely to be related with serious health problems.

TI Provider factors and patient-reported healthcare discrimination in the
Diabetes Study of California (DISTANCE)
SO PATIENT EDUCATION AND COUNSELING
LA English
DT Article
DE Race/ethnicity; Discrimination; Provider factors; Diabetes care; Managed
care
AB Objective: We examined provider-level factors and reported discrimination in the healthcare setting.
Methods: With data from the Diabetes Study of Northern California (DISTANCE) - a race-stratified survey of diabetes patients in Kaiser Permanente Northern California - we analyzed patient-reported racial/ethnic discrimination from providers. Primary exposures were characteristics of the primary care provider (PCP, who coordinates care in this system), including specialty/type, and patient-provider relationship variables, including racial concordance.
Results: Subjects (n = 12,151) included 20% black, 20% Latino, 23% Asian, 30% white, and 6% other patients, with 2-8% reporting discrimination by racial/ethnic group. Patients seeing nurse practitioners as their PCP (OR = 0.09; 95% CI: 0.01-0.67) and those rating their provider higher on communication (OR = 0.70; 95% CI: 0.66-0.74) were less likely to report discrimination, while those with more visits (OR = 1.10; 95% CI: 1.03-1.18) were more likely to report discrimination. Racial concordance was not significant once adjusting for patient race/ethnicity.
Conclusions: Among diverse diabetes patients in managed care, provider type and communication were significantly related to patient-reported discrimination.
Practice implications: Given potential negative impacts on patient satisfaction and treatment decisions, future studies should investigate which interpersonal aspects of the provider-patient relationship reduce patient perceptions of unfair treatment.

TI The role of cultural distance between patient and provider in explaining
racial/ethnic disparities in HIV care
SO PATIENT EDUCATION AND COUNSELING
LA English
DT Article
DE Physician-patient relations; Culture; HIV
AB Objective: We sought to evaluate whether cultural distance between patients and providers was associated with quality of care for people living with HIV/AIDS, and whether cultural distance helped explain racial/ethnic disparities in HIV care.
Methods: We surveyed 437 patients and 45 providers at 4 HIV clinics in the U.S. We examined the association of patients' perceived cultural distance from their providers with patient ratings of healthcare quality, trust in provider, receipt of antiretroviral therapy, medication adherence, and viral suppression. We also examined whether racial/ethnic disparities in these aspects of HIV care were mediated by cultural distance.
Results: Greater cultural distance was associated with lower patient ratings of healthcare quality and less trust in providers. Compared to white patients, nonwhites had significantly lower levels of trust, adherence, and viral suppression. Adjusting for patient-provider cultural distance did not significantly affect any of these disparities (p-values for mediation >.10).
Conclusion: Patient-provider cultural distance was negatively associated with perceived quality of care and trust but did not explain racial/ethnic disparities in HIV care.
Practice implications: Bridging cultural differences may improve patient-provider relationships but may have limited impact in reducing racial/ethnic disparities, unless coupled with efforts to address other sources of unequal care. Published by Elsevier Ireland Ltd.

TI Translating preoperative smoking cessation interventions into routine
clinical care of veterans: provider beliefs
SO TRANSLATIONAL BEHAVIORAL MEDICINE
LA English

DE Smoking cessation; Counseling; Preoperative; Advise; Assess;
Postoperative surgical complications; Primary care clinic; Anesthesia;
Smoking status
AB Smoking among veterans undergoing surgery is estimated to be 36%. Smoking has been linked to postoperative surgical complications including ischemia and cardiac arrhythmias, pneumonia, deep venous thrombosis, pulmonary embolism, and surgical site infection. Preoperative smoking cessation interventions, in which smokers quit at least 6weeks prior to surgery, have been shown to be effective both in smoking cessation and reduction of postoperative complications; however, little is known about physician beliefs regarding the optimal location and the responsible provider for intervention, or whether surgery should be postponed or delayed based on smoking status. Within the routine coordination from medical to surgical care, how should cessation interventions best be implemented? To better inform the translation of preoperative best practices for smoking cessation into clinical care in VA, a survey regarding preoperative smoking cessation beliefs and practices was administered to primary care physicians, surgeons, and anesthesia providers. Chi-square tests were used to examine differences in proportions by provider type. Most providers agreed that the primary care clinic is the best location for intervention, with preoperative and surgical clinics ranked by few as the optimal location (13% and 11%, respectively); most respondents (82%) reported that they would refuse or delay surgery in some cases based on smoking status. There were no differences in either beliefs on location or delay based on provider type. Primary care providers were most likely to advise (86.7%) and assess (80.0%) while anesthesia providers were least likely (59.1% and 22.7%, respectively). Taking time to counsel and the belief that dedicated resources would improve quit rates were associated with advising patients to quit smoking, while being uncomfortable with counseling, the belief that acute health takes precedence and the belief that there is not always time to counsel were identified as barriers to assessing patients for smoking cessation intervention. Primary care providers were more optimistic (100%) that patients would quit if counseled, more often (73.3%) reported having time to counsel, and were less likely to report that acute health takes precedence. Most providers believe that smoking cessation would reduce postoperative complications, with the ideal location for the intervention being the primary care clinic, and that some surgical cases should be delayed for this intervention.

AB OBJECTIVE
To perform a retrospective review aiming to identify causes of renal forniceal rupture.
PATIENTS AND METHODS
A retrospective review was performed of the longitudinal medical record and CT records for patients identified as having renal 'forniceal rupture' or 'calyceal rupture' using a radiological database.
RESULTS
In total, 108 patients were identified with the CT diagnosis of renal 'forniceal' or 'calyceal' rupture.
Forniceal rupture was caused by ureteric stones in 80 cases (74.1%), malignant extrinsic ureteric compression in nine cases (8.3%), benign extrinsic ureteric compression in two cases (1.9%), pelvic-ureteric junction obstruction in two cases (1.9%), vesicoureteric junction (VUJ) obstruction in one case (0.9%), bladder outlet obstruction in one case (0.9%) and iatrogenic causes in four cases (3.7%).
No definitive cause was found in nine cases (8.3%). For patients in whom a ureteric stone was the cause of forniceal rupture, the level of obstruction was proximal ureter in 24.3% of cases, distal ureter in 17.6% of cases and VUJ in 58.1% of cases.
Mean (SD) stone size was 4.09 (2.0) mm. Mean (SD) stone size was 5.34 (1.87) mm for proximal stones, 4.08 (1.69) mm for distal stones and 3.53 (1.96) mm for VUJ stones (P = 0.005).
Urinary tract infection was present in five out of 97 patients (5.2%) in whom data were available for analysis.
CONCLUSION
The most common aetiology of renal forniceal rupture is obstruction caused by distal ureteric stones followed by malignant extrinsic ureteric compression.

AB A retrospective cohort of 436 men with CRPC was used to evaluate the profile of secondary hormonal therapy response in CRPC. Longer duration of primary androgen deprivation therapy was associated with longer duration of secondary hormonal therapy. Men who received the first secondary hormonal treatment for longer than 6 months were more likely to respond to subsequent secondary hormonal therapies.
Background: Androgen receptor (AR) signaling remains important in castration-resistant prostate cancer (CRPC) and sequential responses to hormonal therapies are observed. Little is known about the factors associated with responsiveness to secondary hormone therapy (HT). Methods: We retrospectively identified patients with CRPC who were treated with secondary HT. Patient characteristics and types and duration of secondary HT were analyzed. Selected clinical characteristics and their association with duration of secondary HT were evaluated. Results: Of 436 eligible patients, 321 (74%) and 87 (20%) received at least two or four secondary HT regimens, respectively. Median duration of time on primary androgen deprivation therapy alone (ADT) and secondary HT were 24.0 months (range, 1.5 to 171.8 months) and 30.3 months (range, 0.6 to 156.1+ months), respectively. Patients who received primary ADT >= 24 months received secondary HT for a median duration of 40.0 months, whereas men who received ADT < 24 months had a median duration of 18.4 months on secondary HT (P < .0001). Metastatic disease at secondary HT initiation was associated with a shorter time on secondary HT (P = .0001). Patients who received the first secondary HT for >= 6 months were more likely to have a longer duration on subsequent secondary HT compared with the men who received the first secondary HT < 6 months (P = .0001). Conclusions: Treatment durations of secondary HT are variable. Longer duration of primary ADT was associated with longer duration of secondary HT. These results imply that AR signaling remains an important therapeutic target in CRPC.

AB Cabazitaxel is the first FDA-approved agent for second-line chemotherapy in metastatic castration-resistant prostate cancer (mCRPC) after treatment with docetaxel.
Cabazitaxel can safely be administered to patients with mCRPC, including those with advanced visceral disease and tumor-related disseminated intravascular coagulation (DIC), who are heavily pretreated with docetaxel-containing chemotherapy regimens.
Treatment with cabazitaxel can reverse mCRPC-related DIC and produce objective prostate-specific antigen responses and stabilization of visceral disease.

DE sinus of Valsalva; aneurysm; positron emission tomography/CT
AB An echocardiographic examination performed on a 72-year-old man for assessment of left ventricular hypertrophy revealed a right atrial mass, approximately 4 cm in size, attached to the interatrial septum. Given his history of leiomyosarcoma with vascular invasion, the patient was referred for PET/CT to assess the possibility of metastatic involvement. The results suggested an aneurysmal mass of the aortic noncoronary cusp consistent with a sinus of Valsalva aneurysm. A subsequent CT angiogram and surgery confirmed the diagnosis. To the best of our knowledge, this is the first reported case of a sinus of Valsalva aneurysm detected in PET/CT images.

AB Purpose: Accurate stenosis quantification in the carotid arteries is of great clinical importance. We aimed to compare the diagnostic accuracy of multi-slice computed tomography angiography (CTA) to digital subtraction angiography (DSA) for the detection and grading of atherosclerotic lesions involving the supraaortic arteries.
Materials and methods: We retrospectively analyzed 30 patients (10 women; mean age, 67 years). CTA was performed after administration of 100 ml Ultravist 370 (Bayer Schering, Germany), at a flow of 5 ml/s, using a Philips Brilliance 16MDCT scanner (Philips, Best, Netherland) at a collimation of 16 mm x 0.75 mm prior to DSA. The supraaortic arteries were divided into 17 segments, and, within each segment, the presence and severity of stenotic or occlusive lesions was determined, based on a four-point scale (0-49%, 50-69%, 70-99%, occlusion), by four independent readers using the NASCET criteria. Sensitivity and specificity of MDCT was calculated for the detection of moderate (50-69%) versus significant stenoses (70-99%) and occlusion.
Results: There were 291 segments assessed with both methods. Thirteen lesions were "not assessable" on CTA. DSA identified 53 significant lesions, and CTA 56 significant lesions. With regard to significant lesions, CTA overrated six lesions and underestimated six lesions, resulting in a sensitivity, specificity, and accuracy of 86.4%, 97.6%, and 95.9%, respectively. For the detection of stenoses greater than 50%, sensitivity, specificity, and accuracy were 90.2%, 95.8%, and 94.8%, respectively.
Conclusions: Compared to DSA, CTA shows high accuracy in the detection and grading of lesions involving the supraaortic arteries enabling its use in the detection and treatment planning for stenoses of the supraaortic vessels. (C) 2010 Elsevier Ireland Ltd. All rights reserved.

AB Objective Invasive cancers arising from intraductal papillary mucinous neoplasm (IPMN) are recognised as a morphologically and biologically heterogeneous group of neoplasms. Less is known about the epithelial subtypes of the precursor IPMN from which these lesions arise. The authors investigate the clinicopathological characteristics and the impact on survival of both the invasive component and its background IPMN.
Design and patients The study cohort comprised 61 patients with invasive IPMN (study group) and 570 patients with pancreatic ductal adenocarcinoma (PDAC, control group) resected at a single institution. Multivariate analyses were performed using a stage-matched Cox proportional hazard model.
Results The histology of invasive components of the IPMN cohort was tubular in 38 (62%), colloid in 16 (26%), and oncocytic in seven (12%). Compared with PDAC, invasive IPMNs were associated with a lower incidence of adverse pathological features and improved mortality by multivariate analysis (HR 0.58; 95% CI 0.39 to 0.86). In subtype analysis, this favourable outcome remained only for colloid and oncocytic carcinomas, while tubular adenocarcinoma was associated with worse overall survival, not significantly different from that of PDAC (HR 0.85; 95% CI 0.53 to 1.36). Colloid and oncocytic carcinomas arose only from intestinal- and oncocytic-type IPMNs, respectively, and were mostly of the main-duct type, whereas tubular adenocarcinomas primarily originated in the gastric background, which was often associated with branch-duct IPMN. Overall survival of patients with invasive adenocarcinomas arising from gastric-type IPMN was significantly worse than that of patients with non-gastric-type IPMN (p=0.016).
Conclusions Tubular, colloid and oncocytic invasive IPMNs have varying prognosis, and arise from different epithelial subtypes. Colloid and oncocytic types have markedly improved biology, whereas the tubular type has a course that resembles PDAC. Analysis of these subtypes indicates that the background epithelium plays an equally, if not more, important role in defining the biology and prognosis of invasive IPMNs.

AB Phagocytic responses are critical for effective host defense against opportunistic fungal pathogens. Macrophages sample the phagosomal content and orchestrate the innate immune response. Toll-like receptor 9 (TLR9) recognizes unmethylated CpG DNA and is activated by fungal DNA. Here we demonstrate that specific triggering of TLR9 recruitment to the macrophage phagosomal membrane is a conserved feature of fungi of distinct phylogenetic origins, including Candida albicans, Saccharomyces cerevisiae, Malassezia furfur, and Cryptococcus neoformans. The capacity to trigger phagosomal TLR9 recruitment was not affected by a loss of fungal viability or cell wall integrity. TLR9 deficiency has been linked to increased resistance to murine candidiasis and to restriction of fungal growth in vivo. Macrophages lacking TLR9 demonstrate a comparable capacity for phagocytosis and normal phagosomal maturation compared to wild-type macrophages. We now show that TLR9 deficiency increases macrophage tumor necrosis factor alpha (TNF-alpha) production in response to C. albicans and S. cerevisiae, independent of yeast viability. The increase in TNF-alpha production was reversible by functional complementation of the TLR9 gene, confirming that TLR9 was responsible for negative modulation of the cytokine response. Consistently, TLR9 deficiency enhanced the macrophage effector response by increasing macrophage nitric oxide production. Moreover, microbicidal activity against C. albicans and S. cerevisiae was more efficient in TLR9 knockout (TLR9KO) macrophages than in wild-type macrophages. In conclusion, our data demonstrate that TLR9 is compartmentalized selectively to fungal phagosomes and negatively modulates macrophage antifungal effector functions. Our data support a model in which orchestration of antifungal innate immunity involves a complex interplay of fungal ligand combinations, host cell machinery rearrangements, and TLR cooperation and antagonism.

AB Background: Mitochondrial DNA (mtDNA) variation has been associated with time to progression to AIDS and adverse effects from antiretroviral therapy (ART). In this study, full mitochondrial DNA (mtDNA) sequence data from US-based adult participants in the AIDS Clinical Trials Group study 384 was used to assess associations between mtDNA variants and CD4 T-cell recovery with ART.
Methods: Full mtDNA sequence was determined using chip-based array sequencing. Sequence and CD4 cell count data was available at baseline and after ART initiation for 423 subjects with HIV RNA levels <400 copies per milliliter plasma. The primary outcome was change in CD4 count of >= 100 cells per cubic millimeter from baseline. Analyses were adjusted for baseline age, CD4 cell count, HIV RNA, and naive: memory CD4 cell ratio.
Results: Race-stratified analysis of mtDNA variants with a minor allele frequency >1% revealed multiple mtDNA variants marginally associated (P < 0.05 before Bonferroni correction) with CD4 cell recovery. The most significant single nucleotide polymorphism associations were those tagging the African L2 haplogroup, which was associated with a decreased likelihood of >= 100 cells per cubic millimeter CD4 count increase at week 48 in non-Hispanic blacks (adjusted odds ratio = 0.17; 95% confidence interval = 0.06 to 0.53; P = 0.002).
Conclusions: An African mtDNA haplogroup was associated with CD4 cell recovery after ART in this clinical trial population. These initial findings warrant replication and further investigation to confirm the role of mtDNA variation in CD4 cell recovery during ART.

AB Background: Depression is a major public health problem among youth, currently estimated to affect as many as 9% of US children and adolescents. The recognition that both genes (nature) and environments (nurture) are important for understanding the etiology of depression has led to a rapid growth in research exploring gene-environment interactions (GxE). However, there has been no systematic review of GxE in youth depression to date. Methods: The goal of this article was to systematically review evidence on the contribution of GxE to the risk of child and adolescent depression. Through a search of PubMed and PsycINFO databases to 1 April 2010, we identified 20 candidate gene-environment interaction studies focused on depression in youth (up to age 26) and compared each study in terms of the following characteristics: research design and sample studied; measure of depression and environment used; genes explored; and GxE findings in relation to these factors. Results: In total, 80% of studies (n = 16) found at least one significant GxE association. However, there was wide variation in methods and analyses adopted across studies, especially with respect to environmental measures used and tests conducted to estimate GxE. This heterogeneity made it difficult to compare findings and evaluate the strength of the evidence for GxE. Conclusions: The existing body of GxE research on depression in youth contains studies that are conceptually and methodologically quite different, which contributes to mixed findings and makes it difficult to assess the current state of the evidence. To decrease this heterogeneity, we offer 20 recommendations that are focused on: (a) reporting GxE research; (b) testing and reporting GxE effects; (c) conceptualizing, measuring and analyzing depression; (d) conceptualizing, measuring and analyzing environment; (e) increasing power to test for GxE; and (f) improving the quality of genetic data used. Although targeted to GxE research on depression, these recommendations can be adopted by GxE researchers focusing on other mental health outcomes.

AB This article deals with inconsistency of relative (rather than absolute) treatment effects in binary/dichotomous outcomes. A body of evidence is not rated up in quality if studies yield consistent results, but may be rated down in quality if inconsistent. Criteria for evaluating consistency include similarity of point estimates, extent of overlap of confidence intervals, and statistical criteria including tests of heterogeneity and I(2). To explore heterogeneity, systematic review authors should generate and test a small number of a priori hypotheses related to patients, interventions, outcomes, and methodology. When inconsistency is large and unexplained, rating down quality for inconsistency is appropriate, particularly if some studies suggest substantial benefit, and others no effect or harm (rather than only large vs. small effects).
Apparent subgroup effects may be spurious. Credibility is increased if subgroup effects are based on a small number of a priori hypotheses with a specified direction; subgroup comparisons come from within rather than between studies; tests of interaction generate low P-values; and have a biological rationale.

AB Direct evidence comes from research that directly compares the interventions in which we are interested when applied to the populations in which we are interested and measures outcomes important to patients. Evidence can be indirect in one of four ways. First, patients may differ from those of interest (the term applicability is often used for this form of indirectness). Secondly, the intervention tested may differ from the intervention of interest. Decisions regarding indirectness of patients and interventions depend on an understanding of whether biological or social factors are sufficiently different that one might expect substantial differences in the magnitude of effect.
Thirdly, outcomes may differ from those of primary interest-for instance, surrogate outcomes that are not themselves important, but measured in the presumption that changes in the surrogate reflect changes in an outcome important to patients.
A fourth type of indirectness, conceptually different from the first three, occurs when clinicians must choose between interventions that have not been tested in head-to-head comparisons. Making comparisons between treatments under these circumstances requires specific statistical methods and will be rated down in quality one or two levels depending on the extent of differences between the patient populations, co-interventions, measurements of the outcome, and the methods of the trials of the candidate interventions.

INFORMATION
AB Although the medial-temporal lobes (MTL), PFC, and parietal cortex are considered primary nodes in the episodic memory network, there is much debate regarding the contributions of MTL, PFC, and parietal subregions to recollection versus familiarity (dual-process theory) and the feasibility of accounts on the basis of a single memory strength process (strength theory). To investigate these issues, the current fMRI study measured activity during retrieval of memories that differed quantitatively in terms of strength (high vs. low-confidence trials) and qualitatively in terms of recollection versus familiarity (source vs. item memory tasks). Support for each theory varied depending on which node of the episodic memory network was considered. Results from MTL best fit a dual-process account, as a dissociation was found between a right hippocampal region showing high-confidence activity during the source memory task and bilateral rhinal regions showing high-confidence activity during the item memory task. Within PFC, several left-lateralized regions showed greater activity for source than item memory, consistent with recollective orienting, whereas a right-lateralized ventrolateral area showed low-confidence activity in both tasks, consistent with monitoring processes. Parietal findings were generally consistent with strength theory, with dorsal areas showing low-confidence activity and ventral areas showing high-confidence activity in both tasks. This dissociation fits with an attentional account of parietal functions during episodic retrieval. The results suggest that both dual-process and strength theories are partly correct, highlighting the need for an integrated model that links to more general cognitive theories to account for observed neural activity during episodic memory retrieval.

AB In mice, coat pigmentation requires a stem cell (SC) system in which the survival, proliferation, and differentiation of melanocytes (MCs) are regulated by microenvironments in hair follicles (HFs). In vitro systems are required to analyze the behavior of single melanocyte stem cells (MCSCs) and their potential to form SC systems in vivo. We describe here an experimental system for the isolation, self-renewal, and differentiation of MCSCs, as well as an in vivo reconstitution assay for assessing their potential. Using Dct(tm1(Cre)Bee)/CAG-CAT-GFP mice, we show that, in the presence of stem cell factor and basic fibroblast growth factor and the XB2 feeder cell line, purified MCSCs can undergo clonogenic proliferation, resulting in c-Kit(low) side scatter(low) cells. In culture, these cells maintain their capacity to differentiate and reconstitute an MCSC system in HFs. As these cells are present in the upper part of the HF near the bulge region, express only low levels of housekeeping genes, and are resistant to neonatal treatment with ACK2, it is likely that only MCSCs that are quiescent in vivo have clonogenic activity in vitro. We also found that MCSCs can be purified from wild-type mice by fluorescent cell sorting and can be characterized in vitro.

TI Medicare physician payment rules for 2011: a primer for the
neurointerventionalist
SO JOURNAL OF NEUROINTERVENTIONAL SURGERY
LA English
DT Article
ID HEALTH-CARE
AB Physicians generally have been affected by significant changes in the patterns of medical practice evolving over the past several decades. The Patient Protection and Affordable Care Act of 2010, also called ACA for short, impacts physician professional practice dramatically. Physicians are paid in the USA for their personal services. The payment system is highly variable in the private insurance market; however, governmental systems have a formula based payment, mostly based on the Medicare payment system. Physician services are billed under part B. The Neurointerventional practice is typically performed in a hospital setting. The VA system is a frequently cited successful implementation of a government supported health care program. Availability of neurointerventional services at many VA medical centers is limited. Since the inception of the Medicare program in 1965, several methods have been used to determine the amounts paid to physicians for each covered service. Initially, the payment systems compensated physicians on the basis of their charges. In 1975, just over 10 years after the inception of the Medicare program, payments changed so as not to exceed the increase in medical economic index. The involvement of medical economic index failed to curb increases in costs, leading to the determination of a yearly change in fees by legislation from 1984 to 1991. In 1992, the fee schedule essentially replaced the prior payment system that was based on the physician's charges, which also failed to curb the growth in spending. Thus, in 1998, the sustainable growth rate system was introduced. In 2009, multiple unsuccessful attempts were made by Congress to repeal the formula. The mechanism of the sustainable growth rate includes three components that are incorporated into a statutory formula: expenditure targets, growth rate period and annual adjustments of payment rates for physician services.

AB Purpose: Black men present more frequently with high grade prostate cancer and are more likely to have diabetes mellitus. We evaluated whether there is an independent association between diabetes mellitus and the risk of high grade prostate cancer in men diagnosed with prostate cancer and treated with radiation therapy.
Materials and Methods: A polychotomous logistic regression analysis was performed to evaluate whether a diagnosis of diabetes mellitus was associated with the odds of Gleason score 7 or 8-10 prostate cancer in a cohort of 16,286 men, adjusting for black race, advancing age, prostate specific antigen and digital rectal examination findings.
Results: Black men (adjusted OR 1.84, 95% CI 1.08-3.13, p = 0.024) and non-black men (adjusted OR 1.59, 95% CI 1.33-1.89, p <0.001) with diabetes were more likely to have Gleason score 8-10 vs 6 or less prostate cancer than nondiabetic men. However, this was not true for Gleason score 7 vs 6 or less prostate cancer. Black race was significantly associated with Gleason score 7 vs 6 or less prostate cancer in men without and with diabetes (adjusted OR 1.38, 95% CI 1.17-1.63, p <0.001 and 1.61, 95% CI 1.17-2.21, p = 0.003, respectively). Black race was also associated with Gleason score 8-10 vs 6 or less prostate cancer in men without and with diabetes (adjusted OR 1.36, 95% CI 1.01-1.83, p = 0.04 and 1.58, 95% CI 0.98-2.53, p = 0.06, respectively).
Conclusions: In a cohort of men undergoing radiotherapy for prostate cancer the diagnosis of diabetes mellitus was significantly associated with an increased risk of being diagnosed with Gleason score 8-10 prostate cancer independent of black race.

ID PREVENTION; DISEASE; RISK; TRIAL
AB Purpose: Androgen deprivation therapy is associated with an increased fracture risk. In a recent phase III trial toremifene significantly decreased vertebral fractures in men on androgen deprivation therapy. Similar to other selective estrogen receptor modulators, toremifene was associated with an increase in venous thromboembolic events with the greatest risk in men 80 years old or older. In this post hoc analysis we evaluated the efficacy and safety of toremifene in men younger than 80 years.
Materials and Methods: This analysis included 847 men younger than 80 years, of whom 430 received toremifene 80 mg by mouth daily and 417 received placebo for up to 24 months. The primary end point was new vertebral fractures. Secondary end points included fragility fractures, bone mineral density and safety. Results: Compared with placebo, toremifene decreased the relative risk of new vertebral fractures by 79.5% (95% CI 29.8-94.0, p <0.005). The new vertebral fracture incidence was 1.0% for toremifene and 4.8% for placebo (absolute risk reduction 3.8%). Compared with placebo, toremifene significantly decreased the incidence of nontraumatic fracture or greater than 7% bone loss by 24 months (p <0.0001). Toremifene also significantly increased bone mineral density at all measured sites (all comparisons p <0.001). The incidence of venous thromboembolic events was similar in the toremifene and placebo groups (2.1% and 1.0%, respectively, p = 0.26). The rates of other adverse events were also similar between the groups.
Conclusions: Toremifene significantly decreased new vertebral fractures in men younger than 80 years receiving androgen deprivation therapy for prostate cancer. The risk of venous thromboembolic events was lower than in the overall study population, suggesting an improved risk-benefit profile in younger men.

AB In R5-tropic clade C simian-human immunodeficiency viruses (SHIV-Cs), we identified a 3-asparagine (3N) deletion mutation in the V2 loop stem of gp120 as the major determinant of neutralization escape of the anti-CD4-binding site (anti-CD4-bs) neutralizing monoclonal antibody (nMAb) b12. However, the more potent anti-CD4-bs nMAbs VRC01 and VRC03 were not sensitive to this mutation. Using isogenic tier 1 or tier 2 proviruses differing only in the 3N mutation, we showed that this mutation might result in selective conformational b12 epitope masking. Therefore, human immunodeficiency virus (HIV) Env immunogens targeting the CD4-bs and designed to neutralize tier 2 viruses should take conformational masking by the V2 loop into account.

AB Hypoxia contributes to the pathogenesis of various human diseases, including pulmonary artery hypertension (PAH), stroke, myocardial or cerebral infarction, and cancer. For example, acute hypoxia causes selective pulmonary artery (PA) constriction and elevation of pulmonary artery pressure. Chronic hypoxia induces structural and functional changes to the pulmonary vasculature, which resembles the phenotype of human PAH and is commonly used as an animal model of this disease. The mechanisms that lead to hypoxia-induced phenotypic changes have not been fully elucidated. Here, we show that hypoxia increases type I collagen prolyl-4-hydroxylase [C-P4H(I)], which leads to prolyl-hydroxylation and accumulation of Argonaute2 (Ago2), a critical component of the RNA-induced silencing complex (RISC). Hydroxylation of Ago2 is required for the association of Ago2 with heat shock protein 90 (Hsp90), which is necessary for the loading of microRNAs (miRNAs) into the RISC, and translocation to stress granules (SGs). We demonstrate that hydroxylation of Ago2 increases the level of miRNAs and increases the endonuclease activity of Ago2. In summary, this study identifies hypoxia as a mediator of the miRNA-dependent gene silencing pathway through posttranslational modification of Ago2, which might be responsible for cell survival or pathological responses under low oxygen stress.

AB The incidence of Candida peritonitis is increasing and the mortality rate remains high. Candida albicans is the most common yeast causing Candida peritonitis, but a shift to more drug-resistant non-albicans strains has been observed. Major risk factors for developing Candida peritonitis include hollow viscus perforation, abdominal and thoracic surgery, surgical drains in situ, intravenous and urinary catheters, total parenteral nutrition, severe sepsis, antibiotic therapy (a parts per thousand yen48 h before peritonitis), immunosuppression, diabetes mellitus, and extensive Candida colonization. Polymicrobial peritoneal infections with Candida spp. and enteric bacteria (such as E. coli and B. fragilis) have been associated with higher mortality. Laboratory detection of Candida is still based on histopathological diagnosis and culture-based methods. Isolated Candida spp. must be treated as a pathogen contributing to peritonitis. Prompt diagnosis, effective antifungal therapy, and skilled surgical management are essential components of treatment. Treatment includes removal of all foreign bodies, such as intravenous and urinary catheters and drains, whereas abscesses usually require surgical or radiological drainage. Antifungal therapy should be chosen based on sensitivity profiles. Fluconazole is still appropriate for most severe community-acquired or nosocomial infections. Echinocandins are used as first-line in critically ill patients, those with prior azole exposure, and those with fluconazole-resistant candidiasis. Peritoneal lavage can be used in combination with other antifungal agents to treat refractory infections. Risk factors must be weighed to decide on prophylaxis (usually with fluconazole) to limit antifungal resistance.

AB Patients with major nontraumatic surgical emergencies (NTSEs) are commonly transferred from small hospitals to tertiary care centers. We hypothesized that transferred patients (TRANS) have worse outcomes than patients with similar diagnoses admitted directly to a tertiary center (DIRECT).
We reviewed all patients admitted to the acute care surgery service of our tertiary center (September 1, 2006-October 31, 2009) with one of eight diagnoses indicating a major NTSE. Patients transferred for reasons other than the severity of illness were excluded. Univariate and multivariable analyses compared TRANS and DIRECT patients.
Of 319 patients eligible for analysis, 103 (34%) were TRANS and averaged 3.8 days in the referring hospital before transfer. Compared to DIRECT patients, TRANS patients were more likely to be obese (18.5 vs. 8.0%, P = 0.006) and have cardiac (24 vs. 14%, P = 0.022) or pulmonary (25 vs. 12%, P = 0.003) co-morbidities. TRANS patients were also more likely to present to the tertiary center with hypotension (9 vs. 2%, P = 0.021), tachycardia (20 vs. 13%, P = 0.036), anemia (83 vs. 58%, P < 0.001), and hypoalbuminemia (50 vs. 14%, P < 0.001). TRANS patients had higher mortality (4.9 vs. 0.9%, P = 0.038) and longer hospital stay (8 with 5-13 days vs. 5 with 3-8 days, P < 0.001).
TRANS patients comprised a significant portion of the population with major NTSEs admitted to the acute care surgery service of our tertiary center. They presented with greater physiologic derangement and had worse outcomes than DIRECT patients. As is currently established for trauma care, regionalization of care for NTSEs should be considered.

AB The behavioral response to pain is driven by sensory and affective components, each of which is mediated by the CNS. Subjective pain ratings are used as readouts when appraising potential analgesics; however, pain ratings alone cannot enable a characterization of CNS pain circuitry during pain processing or how this circuitry is modulated pharmacologically. Having a more objective readout of potential analgesic effects may allow improved understanding and detection of pharmacological efficacy for pain. The pharmacological/functional magnetic resonance imaging (phMRI/fMRI) methodology can be used to objectively evaluate drug action on the CNS. In this context, we aimed to evaluate two drugs that had been developed as analgesics: one that is efficacious for pain (buprenorphine (BUP)) and one that failed as an analgesic in clinical trials aprepitant (APREP). Using phMRI, we observed that activation induced solely by BUP was present in regions with mu-opioid receptors, whereas APREP-induced activation was seen in regions expressing NK(1) receptors. However, significant pharmacological modulation of functional connectivity in pain-processing pathways was only observed following BUP administration. By implementing an evoked pain fMRI paradigm, these drugs could also be differentiated by comparing the respective fMRI signals in CNS circuits mediating sensory and affective components of pain. We report a correlation of functional connectivity and evoked pain fMRI measures with pain ratings as well as peak drug concentration. This investigation demonstrates how CNS-acting drugs can be compared, and how the phMRI/fMRI methodology may be used with conventional measures to better evaluate candidate analgesics in small subject cohorts.

RESULTS: Age- and sex-adjusted mortality hazard ratios (FIR) comparing U.S.-born MA, Mexican-born MA, and MCR to NHW were 1.09(95% confidence interval [CI]: 0.86, 1.37), 1.23 (95% Cl: 0.86, 1.76), and 0.97 (95% Cl: 0.77, 1.23), respectively, in nondiabetic individuals; in contrast, mortality risk varied in diabetic individuals with respective HRs of 1.77 (95% Cl: 1.20, 2.61), 1.08 (95% Cl: 0.59, 1.97), and 2.27 (95% Cl: 1.53, 3.35) (interaction p = .0003). Excluding Mexican-born MA and nondiabetic individuals, controlling for medication use, insulin use, fasting glucose levels, and duration of diabetes explained a significant proportion of the mortality differential (HRs relative to NHW were 1.31 [95% Cl: 0.87, 1.981 in U.S.-born MA and 1.38(95% CI: 0.89, 2.121 in MCR).
CONCLUSIONS: This study provides evidence that diabetes is more lethal in U.S.-born MA and MCR than in NHW. Ann Epidemiol 201121:899-906. (C) 2011 Elsevier Inc. All rights reserved.

AB Background: The hypothalamic-pituitary-adrenal axis is a major stress response system hypothesized to be involved in the pathogenesis of posttraumatic stress disorder (PTSD). However, few studies have prospectively examined the relationships among pre-exposure hypothalamic-pituitary-adrenal activity, acute stress reactions and PTSD.
Methods: Two hundred ninety-six police recruits were assessed during academy training before critical incident exposure and provided salivary cortisol at first awakening and after 30 minutes. A measure of cortisol awakening response (CAR) was computed as the change in cortisol level from the first to the second collection. At 12, 24, and 36 months following the start of active police service, officers were assessed for peritraumatic distress, peritraumatic dissociation, acute stress disorder (ASD) symptoms, and PTSD symptoms to their self-identified worst duty-related critical incident. Mixed models for repeated measures were used to analyze the effects of CAR on the outcome variables pooled across the three follow-up assessments.
Results: After controlling for time of awakening, first awakening cortisol levels, and cumulative critical incident stress exposure, CAR during academy training was associated with greater peritraumatic dissociation, beta = .14, z = 3.49, p < .0001, and greater ASD symptoms during police service assessed at 12, 24, and 36 months, beta = .09, Z = 2.03, p < .05, but not with peritraumatic distress, beta = .03, z = .81, p = .42, or PTSD symptoms, beta = -.004, z = -.09, p = .93.
Conclusions: These findings suggest that greater cortisol response to awakening is a pre-exposure risk factor for peritraumatic dissociation and ASD symptoms during police service.

AB Background: Posttraumatic stress disorder (PTSD) is associated with structural and functional compromise of the anterior cingulate cortex (ACC), which may in turn be associated with impairment of its ability to regulate the amygdala. The Val158Met polymorphism in the catechol-O-methyltransferase gene, which substantially influences dopamine inactivation in the frontal lobe in general and in ACC in particular, may moderate ACC integrity in PTSD.
Methods: Wetested this hypothesis in a sample of Vietnam and Persian Gulf War veterans who experienced substantial military operational stress, including 51 who met criteria for PTSD and 48 matched controls who did not.
Results: Participants with PTSD were previously reported to have smaller ACC volumes than controls in this sample. A novel repeated measures analysis of variance was conducted with PTSD diagnosis, Val158Met genotype, and their interaction predicting left and right ACC volume. Genotype was not directly related to ACC volume, but it did significantly interact with the PTSD diagnosis. The difference in ACC volume between the participants without PTSD and participants with PTSD was greater among individuals homozygous for the Val allele than among carriers of the Met allele. This finding was driven largely by the right ACC. Analyses of Caucasian-only, non-Caucasian-only, and male-only subsamples indicated similar patterns.
Conclusions: Our findings suggest Val158Met genotype moderates the effect of PTSD-related processes on right ACC volume.

AB The current report used structural magnetic resonance imaging (MRI) to objectively measure olfactory bulb volume and olfactory sulcal depth in patients diagnosed with chronic schizophrenia and healthy controls. Additional measures were obtained to assess olfactory function. The olfactory bulb and sulcus were manually traced on structural 3T MRIs for 25 right-handed male patients diagnosed with chronic schizophrenia and 25 matched male healthy controls. A sub-set of subjects received the University of Pennsylvania Smell Identification Test (UPSIT). Olfactory bulb volume was significantly decreased in patients with schizophrenia compared to healthy controls, as was their performance on the UPSIT. Additionally, a positive correlation was seen in patients between right bulb volume and UPSIT scores. Overall, our findings support earlier research studies showing morphometric and functional changes in the olfactory system in patients with schizophrenia.

AB The identification of a pelvic mass during pregnancy can often change a time of happiness and exciting anticipation to 1 of anxiety and fearful unknown. Although diagnosed more commonly with the implementation of ultrasonography as part of routine prenatal care, discovering an adnexal mass during pregnancy remains a rare event. Fortunately, the majority of masses are benign and rarely negatively impact pregnancy outcomes; however, no specific protocols exist for the appropriate management of these women. This study will review the most current incidence, management, and outcomes for women diagnosed with an adnexal mass during pregnancy.

AB Qualitative research methodology is more recognized and valued in diabetes behavioral research in recent years. Qualitative methods help clinicians answer questions that quantitative research may not be able to answer, such as exploring patients' motivations, perceptions, and expectations. This paper reviews recent (2005-present) rigorous qualitative studies of children, adolescents, and adult patients with type 1 and type 2 diabetes with the aim of answering the following research question: How has qualitative research contributed to our understanding of behavioral diabetes care? We focus on studies exploring patients', health care providers', and families' interpersonal experiences of diabetes as well as patients' psychosocial experiences of diagnosis and treatment, self-care, complications, and cultural factors. After reviewing the research in each area, we conclude by discussing how qualitative research contributes to our increased understanding of behavioral diabetes.
