AB Antibody switching involves class switch recombination (CSR) events between switch (S) regions located upstream of heavy chain constant (C) genes. Mechanisms targeting CSR to S-regions are not clear. Deletion of S mu, tandem repeat (S mu TR) sequences causes CSR to shift into downstream regions that do not undergo CSR in WT B-cells, including the C mu-region. We now find that, in S mu TR-/- B cells, S mu chromatin histone modification patterns also shift downstream relative to WT and coincide with S mu TR-/- CSR locations. Our results suggest that histone H3 acetylation and methylation are involved in accessibility of switch regions and that these modifications are not dependent on the underlying sequence, but may be controlled by the location of upstream promoter or regulatory elements. Our studies also show RNA polymerase II (RNAPII) loading increases in the E mu/I mu region in stimulated B cells; these increases are independent of S mu TR sequences. Longer S mu deletions have been reported to eliminate increases in RNAPII density, therefore we suggest that sequences between I mu, and S mu, (possibly the I mu, splicing region as well as G-tracts that are involved in stable RNA:DNA complex formation during transcription) might control the RNAPII density increases.

AB Dyskeratosis congenita (DC) is a rare inherited bone marrow failure syndrome caused by mutations in seven genes involved in telomere biology, with approximately 50% of cases remaining genetically uncharacterized. We report a patient with classic DC carrying a compound heterozygous mutation in the CTC1 (conserved telomere maintenance component 1) gene, which has recently implicated in the pleiotropic syndrome Coats plus. This report confirms a molecular link between DC and Coats plus and expands the genotypephenotype complexity observed in telomere-related genetic disorders. Pediatr Blood Cancer 2012;59:311314.

AB Hydroxyurea is the only approved medication in the United States for the treatment of sickle cell anemia (HbSS) and is widely used in children despite an indication limited to adults. We review the evidence of efficacy and safety in children with reference to pivotal adult studies. This evidence and expert opinion form the basis for recommended guidelines for the use of hydroxyurea in children including indications, dosing, therapeutic and safety monitoring, and interventions to improve adherence. However, there are substantial gaps in our knowledge to be addressed by on-going and planned studies in children. Pediatr Blood Cancer 2012;59:365371. (c) 2012 Wiley Periodicals, Inc.

AB Just as syntax differentiates coherent sentences from scrambled word strings, the comprehension of sequential images must also use a cognitive system to distinguish coherent narrative sequences from random strings of images. We conducted experiments analogous to two classic studies of language processing to examine the contributions of narrative structure and semantic relatedness to processing sequential images. We compared four types of comic strips: (1) Normal sequences with both structure and meaning, (2) Semantic Only sequences (in which the panels were related to a common semantic theme, but had no narrative structure), (3) Structural Only sequences (narrative structure but no semantic relatedness), and (4) Scrambled sequences of randomly-ordered panels. In Experiment 1, participants monitored for target panels in sequences presented panel-by-panel. Reaction times were slowest to panels in Scrambled sequences, intermediate in both Structural Only and Semantic Only sequences, and fastest in Normal sequences. This suggests that both semantic relatedness and narrative structure offer advantages to processing. Experiment 2 measured ERPs to all panels across the whole sequence. The N300/N400 was largest to panels in both the Scrambled and Structural Only sequences, intermediate in Semantic Only sequences and smallest in the Normal sequences. This implies that a combination of narrative structure and semantic relatedness can facilitate semantic processing of upcoming panels (as reflected by the N300/N400). Also, panels in the Scrambled sequences evoked a larger left-lateralized anterior negativity than panels in the Structural Only sequences. This localized effect was distinct from the N300/N400, and appeared despite the fact that these two sequence types were matched on local semantic relatedness between individual panels. These findings suggest that sequential image comprehension uses a narrative structure that may be independent of semantic relatedness. Altogether, we argue that the comprehension of visual narrative is guided by an interaction between structure and meaning. (C) 2012 Elsevier Inc. All rights reserved.

AB Macromolecules enter cells by endocytosis and are sorted to different cellular destinations in early/sorting endosomes. The mechanism and regulation of sorting are poorly understood, although transitions between vesicular and tubular endosomes are important. We found that the antihypertensive drug Prazosin inhibits endocytic sorting by an off-target perturbation of the G protein-coupled receptor dopamine receptor D-3 (DRD3). Prazosin is also a potent cytokinesis inhibitor, likely as a consequence of its effects on endosomes. Prazosin stabilizes a normally transient interaction between DRD3 and the coatomer COPI, a complex involved in membrane transport, and shifts endosomal morphology entirely to tubules, disrupting cargo sorting. RNAi depletion of DRD3 alone also inhibits endocytic sorting, indicating a noncanonical role for a G protein-coupled receptor. Prazosin is a powerful tool for rapid and reversible perturbation of endocytic dynamics.

AB The Gram-negative bacteria Yersinia pestis, causative agent of plague, is extremely virulent. One mechanism contributing to Y. pestis virulence is the presence of a type-three secretion system, which injects effector proteins, Yops, directly into immune cells of the infected host. One of these Yop proteins, YopJ, is proapoptotic and inhibits mammalian NF-kappa B and MAP-kinase signal transduction pathways. Although the molecular mechanism remained elusive for some time, recent work has shown that YopJ acts as a serine/threonine acetyl-transferase targeting MAP2 kinases. Using Drosophila as a model system, we find that YopJ inhibits one innate immune NF-kappa B signaling pathway (IMD) but not the other (Toll). In fact, we show YopJ mediated serine/threonine acetylation and inhibition of dTAK1, the critical MAP3 kinase in the IMD pathway. Acetylation of critical serine/threonine residues in the activation loop of Drosophila TAK1 blocks phosphorylation of the protein and subsequent kinase activation. In addition, studies in mammalian cells show similar modification and inhibition of hTAK1. These data present evidence that TAK1 is a target for YopJ-mediated inhibition.

AB Malignant glioma, the most common primary brain tumor, is generally incurable. Although phosphatidylinositol-3-kinase (PI3K) signaling features prominently in glioma, inhibitors generally block proliferation rather than induce apoptosis. Starting with an inhibitor of both lipid and protein kinases that induced prominent apoptosis and that failed early clinical development because of its broad target profile and overall toxicity, we identified protein kinase targets, the blockade of which showed selective synthetic lethality when combined with PI3K inhibitors. Prioritizing protein kinase targets for which there are clinical inhibitors, we demonstrate that cyclin-dependent kinase (CDK)1/2 inhibitors, siRNAs against CDK1/2, and the clinical CDK1/2 inhibitor roscovitine all cooperated with the PI3K inhibitor PIK-90, blocking the antiapoptotic protein Survivin and driving cell death. In addition, overexpression of CDKs partially blocked some of the apoptosis caused by PIK-75. Roscovitine and PIK-90, in combination, were well tolerated in vivo and acted in a synthetic-lethal manner to induce apoptosis in human glioblastoma xenografts. We also tested clinical Akt and CDK inhibitors, demonstrating induction of apoptosis in vitro and providing a preclinical rationale to test this combination therapy in patients.

TI Lung cancers with acquired resistance to EGFR inhibitors occasionally

AB Acquired resistance to EGF receptor (EGFR) tyrosine kinase inhibitors (TKIs) is inevitable in metastatic EGFR-mutant lung cancers. Here, we modeled disease progression using EGFR-mutant human tumor cell lines. Although five of six models displayed alterations already found in humans, one harbored an unexpected secondary NRAS Q61K mutation; resistant cells were sensitive to concurrent EGFR and MEK inhibition but to neither alone. Prompted by this finding and because RAS/RAF/MEK mutations are known mediators of acquired resistance in other solid tumors (colon cancers, gastrointestinal stromal tumors, and melanomas) responsive to targeted therapies, we analyzed the frequency of secondary KRAS/NRAS/ BRAF/MEK1 gene mutations in the largest collection to date of lung cancers with acquired resistance to EGFR TKIs. No recurrent NRAS, KRAS, or MEK1 mutations were found in 212, 195, or 146 patient samples, respectively, but 2 of 195 (1%) were found to have mutations in BRAF (G469A and V600E). Ectopic expression of mutant NRAS or BRAF in drug-sensitive EGFR-mutant cells conferred resistance to EGFR TKIs that was overcome by addition of a MEK inhibitor. Collectively, these positive and negative results provide deeper insight into mechanisms of acquired resistance to EGFR TKIs in lung cancer and inform ongoing clinical trials designed to overcome resistance. In the context of emerging knowledge about mechanisms of acquired resistance to targeted therapies in various cancers, our data highlight the notion that, even though solid tumors share common signaling cascades, mediators of acquired resistance must be elucidated for each disease separately in the context of treatment.

ID SWEPT SEMICONDUCTOR-LASER; FREQUENCY COMB; DEGENERACY; MICROSCOPY; OCT
AB Recent advances in optical coherence tomography (OCT) have led to higher-speed sources that support imaging over longer depth ranges. Limitations in the bandwidth of state-of-the-art acquisition electronics, however, prevent adoption of these advances into the clinical applications. Here, we introduce optical-domain subsampling as a method for imaging at high-speeds and over extended depth ranges but with a lower acquisition bandwidth than that required using conventional approaches. Optically subsampled laser sources utilize a discrete set of wavelengths to alias fringe signals along an extended depth range into a bandwidth limited frequency window. By detecting the complex fringe signals and under the assumption of a depth-constrained signal, optical-domain subsampling enables recovery of the depth-resolved scattering signal without overlapping artifacts from this bandwidth-limited window. We highlight key principles behind optical-domain subsampled imaging, and demonstrate this principle experimentally using a polygon-filter based swept-source laser that includes an intra-cavity Fabry-Perot (FP) etalon.

TI Estimation of sequencing error rates in short reads
SO BMC BIOINFORMATICS
LA English
DT Article
ID GENE-EXPRESSION; HUMAN GENOME; QUALITY; TRANSCRIPTOME; PROJECT; BIASES
AB Background: Short-read data from next-generation sequencing technologies are now being generated across a range of research projects. The fidelity of this data can be affected by several factors and it is important to have simple and reliable approaches for monitoring it at the level of individual experiments.
Results: We developed a fast, scalable and accurate approach to estimating error rates in short reads, which has the added advantage of not requiring a reference genome. We build on the fundamental observation that there is a linear relationship between the copy number for a given read and the number of erroneous reads that differ from the read of interest by one or two bases. The slope of this relationship can be transformed to give an estimate of the error rate, both by read and by position. We present simulation studies as well as analyses of real data sets illustrating the precision and accuracy of this method, and we show that it is more accurate than alternatives that count the difference between the sample of interest and a reference genome. We show how this methodology led to the detection of mutations in the genome of the PhiX strain used for calibration of Illumina data. The proposed method is implemented in an R package, which can be downloaded from http://bcb.dfci.harvard.edu/similar to vwang/shadowRegression.html.
Conclusions: The proposed method can be used to monitor the quality of sequencing pipelines at the level of individual experiments without the use of reference genomes. Furthermore, having an estimate of the error rates gives one the opportunity to improve analyses and inferences in many applications of next-generation sequencing data.

AB We propose and demonstrate an all-optical time-stretch digitizer for real-time capture of ultrafast optical signals, beyond the bandwidths achievable by electronics. This approach uniquely combines four-wave mixing and photonic time-stretch technique to slow down and record high-speed optical signals. As a proof-of-concept, real-time recording of 40-Gb/s non-return-to-zero on-off-keying optical data stream is experimentally demonstrated using a stretch factor of 54 and 1.5-GHz back-end electronic bandwidth. We also report on the observation of dispersion penalty and its mitigation via single-sideband conversion enabled by an optical bandpass filter. Our technique may provide a path to real-time capture of ultrahigh-speed optical data streams. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4742173]

AB Thymus function is thought to depend on a steady supply of T cell progenitors from the bone marrow. The notion that the thymus lacks progenitors with self-renewal capacity is based on thymus transplantation experiments in which host-derived thymocytes replaced thymus-resident cells within 4 wk. Thymus grafting into T cell-deficient mice resulted in a wave of T cell export from the thymus, followed by colonization of the thymus by host-derived progenitors, and cessation of T cell development. Compound Rag2(-/-)gamma(-/-)(c)Kit(W/Wv) mutants lack competitive hematopoietic stem cells (HSCs) and are devoid of T cell progenitors. In this study, using this strain as recipients for wild-type thymus grafts, we noticed thymus-autonomous T cell development lasting several months. However, we found no evidence for export of donor HSCs from thymus to bone marrow. A diverse T cell antigen receptor repertoire in progenitor-deprived thymus grafts implied that many thymocytes were capable of self-renewal. Although the process was most efficient in Rag2(-/-)gamma(-/-)(c)Kit(W/Wv) hosts, gamma(c)-mediated signals alone played a key role in the competition between thymus-resident and bone marrow-derived progenitors. Hence, the turnover of each generation of thymocytes is not only based on short life span but is also driven via expulsion of resident thymocytes by fresh progenitors entering the thymus.

AB Two to three years after infection, a fraction of HIV-1-infected individuals develop serologic activity that neutralizes most viral isolates. Broadly neutralizing antibodies that recognize the HIV-1 envelope protein have been isolated from these patients by single-cell sorting and by neutralization screens. Here, we report a new method for anti-HIV-1 antibody isolation based on capturing single B cells that recognize the HIV-1 envelope protein expressed on the surface of transfected cells. Although far less efficient than soluble protein baits, the cell-based capture method identified antibodies that bind to a new broadly neutralizing epitope in the vicinity of the V3 loop and the CD4-induced site (CD4i). The new epitope is expressed on the cell surface form of the HIV-1 spike, but not on soluble forms of the same envelope protein. Moreover, the new antibodies complement the neutralization spectrum of potent broadly neutralizing anti-CD4 binding site (CD4bs) antibodies obtained from the same individual. Thus, combinations of potent broadly neutralizing antibodies with complementary activity can account for the breadth and potency of naturally arising anti-HIV-1 serologic activity. Therefore, vaccines aimed at eliciting anti-HIV-1 serologic breadth and potency should not be limited to single epitopes.

AB Penetrating brain injury (PBI) is a complex central nervous system injury in which mechanical damage to brain parenchyma results in hemorrhage, ischemia, broad areas of necrosis, and eventually cavitation. The permanent loss of brain tissue affords the possibility of treatment using a biomaterial scaffold to fill the lesion site and potentially deliver pharmacological or cellular therapeutic agents. The administration of cellular therapy may be of benefit in both mitigating the secondary injury process and promoting regeneration through replacement of certain cell populations. This study investigated the survival and differentiation of adult rat hippocampal neural progenitor cells delivered by a collagen scaffold in a rat model of PBI. The cell-scaffold construct was implanted 1 week after injury and was observed to remain intact with open pores upon analysis 4 weeks later. Implanted neural progenitors were found to have survived within the scaffold, and also to have migrated into the surrounding brain. Differentiated phenotypes included astrocytes, oligodendrocytes, vascular endothelial cells, and possibly macrophages. The demonstrated multipotency of this cell population in vivo in the context of traumatic brain injury has implications for regenerative therapies, but additional stimulation appears necessary to promote neuronal differentiation outside normally neurogenic regions.

AB Background: Although global hypomethylation of leukocyte DNA has been associated with an increased risk of several sites of cancer, including breast cancer, determinants of global methylation level among healthy individuals remain largely unexplored. Here, we examined whether postmenopausal endogenous sex hormones were associated with the global methylation level of leukocyte DNA.
Methods: A cross-sectional study was conducted using the control group of a breast cancer case-control study in Nagano, Japan. Subjects were postmenopausal women aged 55 years or over who provided blood samples. We measured global methylation level of peripheral blood leukocyte DNA by luminometric methylation assay; estradiol, estrone, androstenedione, dehydroepiandrosterone sulfate, testosterone and free testosterone by radioimmunoassay; bioavailable estradiol by the ammonium sulfate precipitation method; and sex-hormone binding globulin by immunoradiometric assay. A linear trend of association between methylation and hormone levels was evaluated by regression coefficients in a multivariable liner regression model. A total of 185 women were included in the analyses.
Results: Mean global methylation level (standard deviation) was 70.3% (3.1) and range was from 60.3% to 79.2%. Global methylation level decreased 0.27% per quartile category for estradiol and 0.39% per quartile category for estrone while it increased 0.41% per quartile category for bioavailable estradiol. However, we found no statistically significant association of any sex hormone level measured in the present study with global methylation level of leukocyte DNA.
Conclusions: Our findings suggest that endogenous sex hormones are not major determinants of the global methylation level of leukocyte DNA.

AB Background: Opportunistic oral infections can be found in over 80% of HIV + patients, often causing debilitating lesions that also contribute to deterioration in nutritional health. Although appreciation for the role that the microbiota is likely to play in the initiation and/or enhancement of oral infections has grown considerably in recent years, little is known about the impact of HIV infection on host-microbe interactions within the oral cavity. In the current study, we characterize modulations in the bacterial composition of the lingual microbiome in patients with treated and untreated HIV infection. Bacterial species profiles were elucidated by microarray assay and compared between untreated HIV infected patients, HIV infected patients receiving antiretroviral therapy, and healthy HIV negative controls. The relationship between clinical parameters (viral burden and CD4+ T cell depletion) and the loss or gain of bacterial species was evaluated in each HIV patient group.
Results: In untreated HIV infection, elevated viremia was associated with significantly higher proportions of potentially pathogenic Veillonella, Prevotella, Megasphaera, and Campylobacter species in the lingual microbiome than observed in healthy controls. The upsurge in the prevalence of potential pathogens was juxtaposed by diminished representation of commensal Streptococcus and Veillonella species. Colonization of Neisseria flavescens was lower in the lingual microbiome of HIV infected patients receiving antiretroviral therapy than in uninfected controls.
Conclusions: Our findings provide novel insights into the potential impact of HIV infection and antiretroviral therapy on the community structure of the oral microbiome, and implicate potential mechanisms that may increase the capacity of non-commensal species to gain a stronger foothold.

DT Editorial Material
AB Implementation Science has been published for six years and over that time has gone from receiving 100 articles in 2006 to receiving 354 in 2011; our impact factor has risen from 2.49 in June 2010 to 3.10 in June 2012. Whilst our article publication rate has also risen, it has risen much less slowly than our submission rate-we published 29 papers in 2006 and 134 papers in 2011 and we now publish only around 40 % of submissions. About one-half of submitted manuscripts are rejected without being sent out for peer review; it has become clear that there are a number of common issues that result in manuscripts being rejected at this stage. We hope that by publishing this editorial on our common reasons for rejection without peer review we can help authors to better judge the relevance of their papers to Implementation Science.

AB Introduction: Handoffs are defined as verbal and written communications during patient care transitions. With the passage of recent ACMGE work hour rules further limiting the hours interns can spend in the hospital, many fear that more handoffs will occur, putting patient safety at risk. The issue of handoffs has not been studied in the neurosurgical literature.
Methods: A validated, 20-question online-survey was sent to neurosurgical residents in all 98 accredited U.S. neurosurgery programs. Survey results were analyzed using tabulations.
Results: 449 surveys were completed yielding a 56% response rate. 63% of neurosurgical residents surveyed had not received formal instruction in what constitutes an effective handoff; 24% believe there is high to moderate variability among their co-residents in terms of the quality of the handoff provided; 55% experience three or more interruptions during handoffs on average. 90% of neurosurgical residents surveyed say that handoff most often occurs in a quiet, private area and 56% report a high level of comfort for knowing the potential acute, critical issues affecting a patient when receiving a handoff.
Conclusions: There needs to be more focused education devoted to learning effective patient-care handoffs in neurosurgical training programs. Increasingly, handing off a patient adequately and safely is becoming a required skill of residency.

AB Background: Constitutive production of blood coagulation proteins by hepatocytes is necessary for hemostasis. Stressful conditions trigger adaptive cellular responses and delay processing of most proteins, potentially affecting plasma levels of proteins secreted exclusively by hepatocytes. We examined the effect of glucose deprivation on expression of coagulation proteins by the human hepatoma cell line, HepG2.
Methodology/Principal Findings: Expression of coagulation factor VII, which is required for initiation of blood coagulation, was elevated by glucose deprivation, while expression of other coagulation proteins decreased. Realtime PCR and ELISA demonstrated that the relative percentage expression +/- SD of steady-state F7 mRNA and secreted factor VII antigen were significantly increased (from 100+/-15% to 188+/-27% and 100+/-8.8% to 176.3+/-17.3% respectively, p < 0.001) at 24 hr of treatment. The integrated stress response was induced, as indicated by upregulation of transcription factor ATF4 and of additional stress-responsive genes. Small interfering RNAs directed against ATF4 potently reduced basal F7 expression, and prevented F7 upregulation by glucose deprivation. The response of the endogenous F7 gene was replicated in reporter gene assays, which further indicated that ATF4 effects were mediated via interaction with an amino acid response element in the F7 promoter.
Conclusions/Significance: Our data indicated that glucose deprivation enhanced F7 expression in a mechanism reliant on prior ATF4 upregulation primarily due to increased transcription from the ATF4 gene. Of five coagulation protein genes examined, only F7 was upregulated, suggesting that its functions may be important in a systemic response to glucose deprivation stress.

AB Macrodactyly is a rare family of congenital disorders characterized by the diffuse enlargement of 1 or more digits. Multiple tissue types within the affected digits are involved, but skeletal patterning and gross morphological features are preserved. Not all tissues are equally involved and there is marked heterogeneity with respect to clinical phenotype. The molecular mechanisms responsible for these growth disturbances offer unique insight into normal limb growth and development, in general. To date, no genes or loci have been implicated in the development of macrodactyly. In this study, we performed the first transcriptional profiling of macrodactyly tissue. We found that pleiotrophin (PTN) was significantly overexpressed across all our macrodactyly samples. The mitogenic functions of PTN correlate closely with the clinical characteristics of macrodactyly. PTN thus represents a promising target for further investigation into the etiology of overgrowth phenotypes.

AB In Huntington's disease (HD; MIM ID # 143100), a fatal neurodegenerative disorder, transcriptional dysregulation is a key pathogenic feature. Histone modifications are altered in multiple cellular and animal models of HD suggesting a potential mechanism for the observed changes in transcriptional levels. In particular, previous work has suggested an important link between decreased histone acetylation, particularly acetylated histone H3 (AcH3; H3K9K14ac), and downregulated gene expression. However, the question remains whether changes in histone modifications correlate with transcriptional abnormalities across the entire transcriptome. Using chromatin immunoprecipitation paired with microarray hybridization (ChIP-chip), we interrogated AcH3-gene interactions genome-wide in striata of 12-week old wild-type (WT) and transgenic (TG) R6/2 mice, an HD mouse model, and correlated these interactions with gene expression levels. At the level of the individual gene, we found decreases in the number of sites occupied by AcH3 in the TG striatum. In addition, the total number of genes bound by AcH3 was decreased. Surprisingly, the loss of AcH3 binding sites occurred within the coding regions of the genes rather than at the promoter region. We also found that the presence of AcH3 at any location within a gene strongly correlated with the presence of its transcript in both WT and TG striatum. In the TG striatum, treatment with histone deacetylase (HDAC) inhibitors increased global AcH3 levels with concomitant increases in transcript levels; however, AcH3 binding at select gene loci increased only slightly. This study demonstrates that histone H3 acetylation at lysine residues 9 and 14 and active gene expression are intimately tied in the rodent brain, and that this fundamental relationship remains unchanged in an HD mouse model despite genome-wide decreases in histone H3 acetylation.

TI Protection against High-Dose Highly Pathogenic Mucosal SIV Challenge at

AB Passive transfer studies using monoclonal or polyclonal antibodies in the macaque model have been valuable for determining conditions for antibody protection against immunodeficiency virus challenge. Most studies have employed hybrid simian/human immunodeficiency virus (SHIV) challenge in conjunction with neutralizing human monoclonal antibodies. Passive protection against SIV, particularly the pathogenic prototype virus SIVmac239, has been little studied because of the paucity of neutralizing antibodies to this virus. Here, we show that the antibody-like molecule CD4-IgG2 potently neutralizes SIVmac239 in vitro. When administered by an osmotic pump to maintain concentrations given the short half-life of CD4-IgG2 in macaques, the molecule provided sterilizing immunity/protection against high-dose mucosal viral challenge to a high proportion of animals (5/7 at a 200 mg dose CD4-IgG2 and 3/6 at a 20 mg dose) at serum concentrations below 1.5 mu g/ml. The neutralizing titers of such sera were predicted to be very low and indeed sera at a 1: 4 dilution produced no neutralization in a pseudovirus assay. Macaque anti-human CD4 titers did develop weakly at later time points in some animals but were not associated with the level of protection against viral challenge. The results show that, although SIVmac239 is considered a highly pathogenic virus for which vaccine-induced T cell responses in particular have provided limited benefit against high dose challenge, the antibody-like CD4-IgG2 molecule at surprisingly low serum concentration affords sterilizing immunity/protection to a majority of animals.

TI PAK1 Kinase Promotes Cell Motility and Invasiveness through CRK-II

AB The role of c-Crk (CRK) in promoting metastasis is well described however the role of CRK phosphorylation and the corresponding signaling events are not well explained. We have observed CRK-II serine 41 phosphorylation is inversely correlated with p120-catenin and E-cadherin expressions in non-small cell lung cancer (NSCLC) cells. Therefore, we investigated the role of CRK-II serine 41 phosphorylation in the down-regulation of p120-catenin, cell motility and cell invasiveness in NSCLC cells. For this purpose, we expressed phosphomimetic and phosphodeficient CRK-II serine 41 mutants in NSCLC cells. NSCLC cells expressing phosphomimetic CRK-II seine 41 mutant showed lower p120-catenin level while CRK-II seine 41 phosphodeficient mutant expression resulted in higher p120-catenin. In addition, A549 cells expressing CRK-II serine 41 phosphomimetic mutant demonstrated more aggressive behavior in wound healing and invasion assays and, on the contrary, expression of phosphodeficient CRK-II serine 41 mutant in A549 cells resulted in reduced cell motility and invasiveness. We also provide evidence that PAK1 mediates CRK-II serine 41 phosphorylation. RNAi mediated silencing of PAK1 increased p120-catenin level in A549 and H157 cells. Furthermore, PAK1 silencing decreased cell motility and invasiveness in A549 cells. These effects were abrogated in A549 cells expressing phosphomimetic CRK-II serine 41. In summary, these data provide evidence for the role of PAK1 in the promotion of cell motility, cell invasiveness and the down regulation of p120-catenin through CRK serine 41 phosphorylation in NSCLC cells.

AB To catalyze ion transport, the Na,K-ATPase must contain one alpha and one beta subunit. When expressed by transfection in various expression systems, each of the four alpha subunit isoforms can assemble with each of the three beta subunit isoforms and form an active enzyme, suggesting the absence of selective alpha-beta isoform assembly. However, it is unknown whether in vivo conditions the alpha-beta assembly is random or isoform-specific. The alpha(2)-beta(2) complex was selectively immunoprecipitated by both anti-alpha(2) and anti-beta(2) antibodies from extracts of mouse brain, which contains cells co-expressing multiple Na,K-ATPase isoforms. Neither alpha(1)-beta(2) nor alpha(2)-beta(1) complexes were detected in the immunoprecipitates. Furthermore, in MDCK cells co-expressing alpha(1), beta(1), and beta(2) isoforms, a greater fraction of the beta(2) subunits was unassembled with alpha(1) as compared with that of the beta(1) subunits, indicating preferential association of the alpha(1) isoform with the beta(1) isoform. In addition, the alpha(1)-beta(2) complex was less resistant to various detergents than the alpha(1)-beta(1) complex isolated from MDCK cells or the alpha(2)-beta(2) complex isolated from mouse brain. Therefore, the diversity of the alpha-beta Na,K-ATPase heterodimers in vivo is determined not only by cell-specific co-expression of particular isoforms, but also by selective association of the alpha and beta subunit isoforms.

AB Age-group analyses were conducted of patients in the prophylactic platelet dose trial (PLADO), which evaluated the relation between platelet dose per transfusion and bleeding. Hospitalized patients with treatment-induced hypoproliferative thrombocytopenia were randomly assigned to 1 of 3 platelet doses: 1.1 x 10(11), 2.2 x 10(11), or 4.4 x 10(11) platelets/m(2) per transfusion, given for morning counts of <= 10 000 platelets/mu L. Daily hemostatic assessments were performed. The primary end point (percentage of patients who developed grade 2 or higher World Health Organization bleeding) was evaluated in 198 children (0-18 years) and 1044 adults. Although platelet dose did not predict bleeding for any age group, children overall had a significantly higher risk of grade 2 or higher bleeding than adults (86%, 88%, 77% vs 67% of patients aged 0-5 years, 6-12 years, 13-18 years, vs adults, respectively) and more days with grade 2 or higher bleeding (median, 3 days in each pediatric group vs 1 day in adults; P < .001). The effect of age on bleeding differed by disease treatment category and was most pronounced among autologous transplant recipients. Pediatric subjects were at higher risk of bleeding over a wide range of platelet counts, indicating that their excess bleeding risk may be because of factors other than platelet counts. This trial was registered at www.clinicaltrials.gov as #NCT00128713. (Blood. 2012; 120(4):748-760)

AB Despite the introduction of tyrosine kinase inhibitor therapy, the prognosis for p190-BCR-ABL(+) acute lymphoblastic leukemia remains poor. In the present study, we present the cellular and molecular roles of the Rho GTPase guanine nucleotide exchange factor Vav in lymphoid leukemogenesis and explore the roles of Vav proteins in BCR-ABL-dependent signaling. We show that genetic deficiency of the guanine nucleotide exchange factor Vav3 delays leukemogenesis by p190-BCR-ABL and phenocopies the effect of Rac2 deficiency, a downstream effector of Vav3. Compensatory up-regulation of expression and activation of Vav3 in Vav1/Vav2-deficient B-cell progenitors increases the transformation ability of p190-BCR-ABL. Vav3 deficiency induces apoptosis of murine and human leukemic lymphoid progenitors, decreases the activation of Rho GTPase family members and p21-activated kinase, and is associated with increased Bad phosphorylation and up-regulation of Bax, Bak, and Bik. Finally, Vav3 activation only partly depends on ABL TK activity, and Vav3 deficiency collaborates with tyrosine kinase inhibitors to inhibit CrkL activation and impair leukemogenesis in vitro and in vivo. We conclude that Vav3 represents a novel specific molecular leukemic effector for multitarget therapy in p190-BCR-ABL-expressng acute lymphoblastic leukemia. (Blood. 2012;120(4):800-811)

AB The outcome of allogeneic HSCT varies considerably by the disease and remission status at the time of transplantation. Any retrospective or prospective HSCT study that enrolls patients across disease types must account for this heterogeneity; yet, current methods are neither standardized nor validated. We conducted a retrospective study of 1539 patients who underwent transplantation at Dana-Farber Cancer Institute/Brigham and Women's Hospital from 2000 to 2009. Using multivariable models for overall survival, we created a disease risk index. This tool uses readily available information about disease and disease status to categorize patients into 4 risk groups with significantly different overall survival and progression-free survival on the basis of primarily differences in the relapse risk. This scheme applies regardless of conditioning intensity, is independent of comorbidity index, and was validated in an independent cohort of 672 patients from the Fred Hutchinson Cancer Research Center. This simple and validated scheme could be used to risk-stratify patients in both retrospective and prospective HSCT studies, to calibrate HSCT outcomes across studies and centers, and to promote the design of HSCT clinical trials that enroll patients across diseases and disease states, increasing our ability to study nondisease-specific outcomes in HSCT.

AB We synthesized 5-allyl-1-methyl-5-(m-trifluoromethyl-diazirynylphenyl)barbituric acid (14), a trifluoromethyldiazirine-containing derivative of general anesthetic mephobarbital, separated the racemic mixture into enantiomers by chiral chromatography, and determined the configuration of the (+)-enantiomer as S by X-ray crystallography. Additionally, we obtained the H-3-labeled ligand with high specific radioactivity. R-(-)-14 is an order of magnitude more potent than the most potent clinically used barbiturate, thiopental, and its general anesthetic EC50 approaches those for propofol and etomidate, whereas S-(+)-14 is 10-fold less potent. Furthermore, at concentrations close to its anesthetic potency, R-(-)-14 both potentiated GABA-induced currents and increased the affinity for the agonist muscimol in human alpha 1 beta 2/3 gamma 2L GABA(A) receptors. Finally, R-()-14 was found to be an exceptionally efficient photolabeling reagent, incorporating into both alpha 1 and beta 3 subunits of human alpha 1 beta 3 GABA(A) receptors. These results indicate R-(-)-14 is a functional general anesthetic that is well-suited for identifying barbiturate binding sites on Cys-loop receptors.

TI Interpreting cancer genomes using systematic host network perturbations
by tumour virus proteins
SO NATURE

DT Article

MUTATIONS; COMPLEX
AB Genotypic differences greatly influence susceptibility and resistance to disease. Understanding genotype-phenotype relationships requires that phenotypes be viewed as manifestations of network properties, rather than simply as the result of individual genomic variations(1). Genome sequencing efforts have identified numerous germline mutations, and large numbers of somatic genomic alterations, associated with a predisposition to cancer(2). However, it remains difficult to distinguish background, or 'passenger', cancer mutations from causal, or 'driver', mutations in these data sets. Human viruses intrinsically depend on their host cell during the course of infection and can elicit pathological phenotypes similar to those arising from mutations(3). Here we test the hypothesis that genomic variations and tumour viruses may cause cancer through related mechanisms, by systematically examining host interactome and transcriptome network perturbations caused by DNA tumour virus proteins. The resulting integrated viral perturbation data reflects rewiring of the host cell networks, and highlights pathways, such as Notch signalling and apoptosis, that go awry in cancer. We show that systematic analyses of host targets of viral proteins can identify cancer genes with a success rate on a par with their identification through functional genomics and large-scale cataloguing of tumour mutations. Together, these complementary approaches increase the specificity of cancer gene identification. Combining systems-level studies of pathogen-encoded gene products with genomic approaches will facilitate the prioritization of cancer-causing driver genes to advance the understanding of the genetic basis of human cancer.

AB Drug resistance presents a challenge to the treatment of cancer patients. Many studies have focused on cell-autonomous mechanisms of drug resistance. By contrast, we proposed that the tumour micro-environment confers innate resistance to therapy. Here we developed a co-culture system to systematically assay the ability of 23 stromal cell types to influence the innate resistance of 45 cancer cell lines to 35 anticancer drugs. We found that stroma-mediated resistance is common, particularly to targeted agents. We characterized further the stroma-mediated resistance of BRAF-mutant melanoma to RAF inhibitors because most patients with this type of cancer show some degree of innate resistance(1-4). Proteomic analysis showed that stromal cell secretion of hepatocyte growth factor (HGF) resulted in activation of the HGF receptor MET, reactivation of the mitogen-activated protein kinase (MAPK) and phosphatidylinositol-3-OH kinase (PI(3)K)-AKT signalling pathways, and immediate resistance to RAF inhibition. Immunohistochemistry experiments confirmed stromal cell expression of HGF in patients with BRAF-mutant melanoma and showed a significant correlation between HGF expression by stromal cells and innate resistance to RAF inhibitor treatment. Dual inhibition of RAF and either HGF or MET resulted in reversal of drug resistance, suggesting RAF plus HGF or MET inhibitory combination therapy as a potential therapeutic strategy for BRAF-mutant melanoma. A similar resistance mechanism was uncovered in a subset of BRAF-mutant colorectal and glioblastoma cell lines. More generally, this study indicates that the systematic dissection of interactions between tumours and their micro-environment can uncover important mechanisms underlying drug resistance.

TI RNA sequencing of pancreatic circulating tumour cells implicates WNT
signalling in metastasis
SO NATURE
LA English
DT Article
ID STEM-CELL; TRANSCRIPTOME; PATHWAY
AB Circulating tumour cells (CTCs) shed into blood from primary cancers include putative precursors that initiate distal metastases(1). Although these cells are extraordinarily rare, they may identify cellular pathways contributing to the blood-borne dissemination of cancer. Here, we adapted a microfluidic device(2) for efficient capture of CTCs from an endogenous mouse pancreatic cancer model(3) and subjected CTCs to single-molecule RNA sequencing(4), identifying Wnt2 as a candidate gene enriched in CTCs. Expression of WNT2 in pancreatic cancer cells suppresses anoikis, enhances anchorage-independent sphere formation, and increases metastatic propensity in vivo. This effect is correlated with fibronectin upregulation and suppressed by inhibition of MAP3K7 (also known as TAK1) kinase. In humans, formation of non-adherent tumour spheres by pancreatic cancer cells is associated with upregulation of multiple WNT genes, and pancreatic CTCs revealed enrichment for WNT signalling in 5 out of 11 cases. Thus, molecular analysis of CTCs may identify candidate therapeutic targets to prevent the distal spread of cancer.

AB BACKGROUND
It is unclear whether an evaluation incorporating coronary computed tomographic angiography (CCTA) is more effective than standard evaluation in the emergency department in patients with symptoms suggestive of acute coronary syndromes.
METHODS
In this multicenter trial, we randomly assigned patients 40 to 74 years of age with symptoms suggestive of acute coronary syndromes but without ischemic electrocardiographic changes or an initial positive troponin test to early CCTA or to standard evaluation in the emergency department on weekdays during daylight hours between April 2010 and January 2012. The primary end point was length of stay in the hospital. Secondary end points included rates of discharge from the emergency department, major adverse cardiovascular events at 28 days, and cumulative costs. Safety end points were undetected acute coronary syndromes.
RESULTS
The rate of acute coronary syndromes among 1000 patients with a mean (+/- SD) age of 54 +/- 8 years (47% women) was 8%. After early CCTA, as compared with standard evaluation, the mean length of stay in the hospital was reduced by 7.6 hours (P<0.001) and more patients were discharged directly from the emergency department (47% vs. 12%, P<0.001). There were no undetected acute coronary syndromes and no significant differences in major adverse cardiovascular events at 28 days. After CCTA, there was more downstream testing and higher radiation exposure. The cumulative mean cost of care was similar in the CCTA group and the standard-evaluation group ($4,289 and $4,060, respectively; P = 0.65).
CONCLUSIONS
In patients in the emergency department with symptoms suggestive of acute coronary syndromes, incorporating CCTA into a triage strategy improved the efficiency of clinical decision making, as compared with a standard evaluation in the emergency department, but it resulted in an increase in downstream testing and radiation exposure with no decrease in the overall costs of care.

TI Lack of Modulation of Nicotinic Acetylcholine Alpha-7 Receptor Currents

AB Kynurenic acid (KYNA), a classical ionotropic glutamate receptor antagonist is also purported to block the alpha 7-subtype nicotinic acetylcholine receptor (alpha 7* nAChR). Although many published studies cite this potential effect, few have studied it directly. In this study, the alpha 7*-selective agonist, choline, was pressure-applied to interneurons in hippocampal subregions, CA1 stratum radiatum and hilus of acute brain hippocampal slices from adolescent to adult mice and adolescent rats. Stable alpha 7* mediated whole-cell currents were measured using voltage-clamp at physiological temperatures. The effects of bath applied KYNA on spontaneous glutamatergic excitatory postsynaptic potentials (sEPSC) as well as choline-evoked alpha 7* currents were determined. In mouse hilar interneurons, KYNA totally blocked sEPSC whole-cell currents in a rapid and reversible manner, but had no effect on choline-evoked alpha 7* whole-cell currents. To determine if this lack of KYNA effect on alpha 7* function was due to regional and/or species differences in alpha 7* nAChRs, the effects of KYNA on choline-evoked alpha 7* whole-cell currents in mouse and rat stratum radiatum interneurons were tested. KYNA had no effect on either mouse or rat stratum radiatum interneuron choline-evoked alpha 7* whole-cell currents. Finally, to test whether the lack of effect of KYNA was due to unlikely slow kinetics of KYNA interactions with alpha 7* nAChRs, recordings of alpha 7*-mediated currents were made from slices that were prepared and stored in the presence of 1 mM KYNA (>90 minutes exposure). Under these conditions, KYNA had no measurable effect on alpha 7* nAChR function. The results show that despite KYNA-mediated blockade of glutamatergic sEPSCs, two types of hippocampal interneurons that express choline-evoked alpha 7* nAChR currents fail to show any degree of modulation by KYNA. Our results indicate that under our experimental conditions, which produced complete KYNA-mediated blockade of sEPSCs, claims of KYNA effects on choline-evoked alpha 7* nAChR function should be made with caution.

TI Rapamycin Reverses Elevated mTORC1 Signaling in Lamin A/C-Deficient

AB Mutations in LMNA, the gene that encodes A-type lamins, cause multiple diseases including dystrophies of the skeletal muscle and fat, dilated cardiomyopathy, and progeria-like syndromes (collectively termed laminopathies). Reduced A-type lamin function, however, is most commonly associated with skeletal muscle dystrophy and dilated cardiomyopathy rather than lipodystrophy or progeria. The mechanisms underlying these diseases are only beginning to be unraveled. We report that mice deficient in Lmna, which corresponds to the human gene LMNA, have enhanced mTORC1 (mammalian target of rapamycin complex 1) signaling specifically in tissues linked to pathology, namely, cardiac and skeletal muscle. Pharmacologic reversal of elevated mTORC1 signaling by rapamycin improves cardiac and skeletal muscle function and enhances survival in mice lacking A-type lamins. At the cellular level, rapamycin decreases the number of myocytes with abnormal desmin accumulation and decreases the amount of desmin in both muscle and cardiac tissue of Lmna(-/-) mice. In addition, inhibition of mTORC1 signaling with rapamycin improves defective autophagic-mediated degradation in Lmna(-/-) mice. Together, these findings point to aberrant mTORC1 signaling as a mechanistic component of laminopathies associated with reduced A-type lamin function and offer a potential therapeutic approach, namely, the use of rapamycin-related mTORC1 inhibitors.

AB Traumatic brain injury (TBI) is one of the most robust environmental risk factors for Alzheimer's disease (AD). Compelling evidence is accumulating that a single event of TBI is associated with increased levels of A beta. However, the underlying molecular mechanisms remain unknown. We report here that the BACE1 interacting protein, GGA3, is depleted while BACE1 levels increase in the acute phase after injury (48 h) in a mouse model of TBI. We further demonstrated the role of GGA3 in the regulation of BACE1 in vivo by showing that BACE1 levels are increased in the brain of GGA3-null mice. We next found that head trauma potentiates BACE1 elevation in GGA3-null mice in the acute phase after TBI, and discovered that GGA1, a GGA3 homolog, is a novel caspase-3 substrate depleted at 48 h after TBI. Moreover, GGA1 silencing potentiates BACE1 elevation induced by GGA3 deletion in neurons in vitro, indicating that GGA1 and GGA3 synergistically regulate BACE1. Accordingly, we found that levels of both GGA1 and GGA3 are depleted while BACE1 levels are increased in a series of postmortem AD brains. Finally, we show that GGA3 haploinsufficiency results in sustained elevation of BACE1 and A beta levels while GGA1 levels are restored in the subacute phase (7 d) after injury. In conclusion, our data indicate that depletion of GGA1 and GGA3 engender a rapid and robust elevation of BACE1 in the acute phase after injury. However, the efficient disposal of the acutely accumulated BACE1 solely depends on GGA3 levels in the subacute phase of injury.

AB Context Cardiovascular disease is increased in patients with human immunodeficiency virus (HIV), but the specific mechanisms are unknown.
Objective To assess arterial wall inflammation in HIV, using (18)fluorine-2-deoxy-D-glucose positron emission tomography (F-18-FDG-PET), in relationship to traditional and nontraditional risk markers, including soluble CD163 (sCD163), a marker of monocyte and macrophage activation.
Design, Setting, and Participants A cross-sectional study of 81 participants investigated between November 2009 and July 2011 at the Massachusetts General Hospital. Twenty-seven participants with HIV without known cardiac disease underwent cardiac 18F-FDG-PET for assessment of arterial wall inflammation and coronary computed tomography scanning for coronary artery calcium. The HIV group was compared with 2 separate non-HIV control groups. One control group (n=27) was matched to the HIV group for age, sex, and Framingham risk score (FRS) and had no known atherosclerotic disease (non-HIV FRS-matched controls). The second control group (n=27) was matched on sex and selected based on the presence of known atherosclerotic disease (non-HIV atherosclerotic controls).
Main Outcome Measure Arterial inflammation was prospectively determined as the ratio of FDG uptake in the arterial wall of the ascending aorta to venous background as the target-to-background ratio (TBR).
Results Participants with HIV demonstrated well-controlled HIV disease (mean [SD] CD4 cell count, 641 [288] cells/mu L; median [interquartile range] HIV-RNA level, <48 [<48 to <48] copies/mL). All were receiving antiretroviral therapy (mean [SD] duration, 12.3 [4.3] years). The mean FRS was low in both HIV and non-HIV FRS-matched control participants (6.4; 95% CI, 4.8-8.0 vs 6.6; 95% CI, 4.9-8.2; P=.87). Arterial inflammation in the aorta (aortic TBR) was higher in the HIV group vs the non-HIV FRS-matched control group (2.23; 95% CI, 2.07-2.40 vs 1.89; 95% CI, 1.80-1.97; P < .001), but was similar compared with the non-HIV atherosclerotic control group (2.23; 95% CI, 2.07-2.40 vs 2.13; 95% CI, 2.03-2.23; P=.29). Aortic TBR remained significantly higher in the HIV group vs the non-HIV FRS-matched control group after adjusting for traditional cardiovascular risk factors (P=.002) and in stratified analyses among participants with undetectable viral load, zero calcium, FRS of less than 10, a low-density lipoprotein cholesterol level of less than 100 mg/dL (<2.59 mmol/L), no statin use, and no smoking (all P <= .01). Aortic TBR was associated with sCD163 level (P=.04) but not with C-reactive protein (P=.65) or D-dimer (P=.08) among patients with HIV.
Conclusion Participants infected with HIV vs noninfected control participants with similar cardiac risk factors had signs of increased arterial inflammation, which was associated with a circulating marker of monocyte and macrophage activation. JAMA. 2012;308(4):379-386 www.jama.com

TI The Effect of Systematic Clinical Interventions with Cigarette Smokers
on Quit Status and the Rates of Smoking-Related Primary Care Office
Visits
SO PLOS ONE
LA English
DT Article
AB Background: The United States Public Health Service (USPHS) Guideline for Treating Tobacco Use and Dependence includes ten key recommendations regarding the identification and the treatment of tobacco users seen in all health care settings. To our knowledge, the impact of system-wide brief interventions with cigarette smokers on smoking prevalence and health care utilization has not been examined using patient population-based data.
Methods and Findings: Data on clinical interventions with cigarette smokers were examined for primary care office visits of 104,639 patients at 17 Harvard Vanguard Medical Associates (HVMA) sites. An operational definition of "systems change" was developed. It included thresholds for intervention frequency and sustainability. Twelve sites met the criteria. Five did not. Decreases in self-reported smoking prevalence were 40% greater at sites that achieved systems change (13.6% vs. 9.7%, p<.01). On average, the likelihood of quitting increased by 2.6% (p<0.05, 95% CI: 0.1%-4.6%) per occurrence of brief intervention. For patients with a recent history of current smoking whose home site experienced systems change, the likelihood of an office visit for smoking-related diagnoses decreased by 4.3% on an annualized basis after systems change occurred (p<0.05, 95% CI: 0.5%-8.1%). There was no change in the likelihood of an office visit for smoking-related diagnoses following systems change among non-smokers.
Conclusions: The clinical practice data from HVMA suggest that a systems approach can lead to significant reductions in smoking prevalence and the rate of office visits for smoking-related diseases. Most comprehensive tobacco intervention strategies focus on the provider or the tobacco user, but these results argue that health systems should be included as an integral component of a comprehensive tobacco intervention strategy. The HVMA results also give us an indication of the potential health impacts when meaningful use core tobacco measures are widely adopted.

AB Progestin resistance is a major obstacle to treating early stage, well-differentiated endometrial cancer as well as recurrent endometrial cancer. The mechanism behind the suboptimal response to progestin is not well understood. The PTEN tumor suppressor gene is frequently mutated in type I endometrial cancers and this mutation results in hyperactivation of the PI3K/AKT pathway. We hypothesized that increased activation of AKT promotes an inadequate response to progestins in endometrial cancer cells. Ishikawa cells stably transfected with progesterone receptor B (PRB23 cells) were treated with the AKT inhibitor, MK-2206, which effectively decreased levels of p(Ser473)-AKT in a dose-dependent (10 nM to 1 uM) and time-dependent manner (0.5 h to 24 h). MK-2206 inhibited levels of p(Thr308)-AKT and a downstream target, p(Thr246)-PRAS40, but did not change levels of p(Thr202/Tyr204) ERK or p(Thr13/Tyr185) SAPK/JNK, demonstrating specificity of MK-2206 for AKT. Additionally, MK-2206 treatment of PRB23 cells resulted in a significant increase in levels of progesterone receptor B (PRB) protein. Microarray analysis of PRB23 cells identified PDK4 as the most highly upregulated gene among 70 upregulated genes in response to R5020. Inhibition of AKT further upregulated progestin-mediated expression of PDK4 but did not affect another progestin-responsive gene, SGK1. Treatment of PRB23 cells with R5020 and MK-2206 independently decreased viability of cells while the combination of R5020 and MK-2206 caused the greatest decrease in cell viability. Furthermore, mice with xenografted tumors treated with MK-2206 alone or with progesterone alone exhibited modest reductions in their tumor volume. The largest decrease in tumor size was observed in the mice treated with both MK-2206 and progesterone; these tumors exhibited the least proliferation (Ki67) and the most apoptosis (cleaved caspase-3) of all the treatment groups. In summary, inhibition of AKT stabilizes the Progesterone Receptor B and augments progesterone response in endometrial cancer cells that have hyperactivated AKT.

AB Rapid advances in DNA sequencing promise to enable new diagnostics and individualized therapies. Achieving personalized medicine, however, will require extensive research on highly reidentifiable, integrated datasets of genomic and health information. To assist with this, participants in the Personal Genome Project choose to forgo privacy via our institutional review board-approved "open consent" process. The contribution of public data and samples facilitates both scientific discovery and standardization of methods. We present our findings after enrollment of more than 1,800 participants, including whole-genome sequencing of 10 pilot participant genomes (the PGP-10). We introduce the Genome-Environment-Trait Evidence (GET-Evidence) system. This tool automatically processes genomes and prioritizes both published and novel variants for interpretation. In the process of reviewing the presumed healthy PGP-10 genomes, we find numerous literature references implying serious disease. Although it is sometimes impossible to rule out a late-onset effect, stringent evidence requirements can address the high rate of incidental findings. To that end we develop a peer production system for recording and organizing variant evaluations according to standard evidence guidelines, creating a public forum for reaching consensus on interpretation of clinically relevant variants. Genome analysis becomes a two-step process: using a prioritized list to record variant evaluations, then automatically sorting reviewed variants using these annotations. Genome data, health and trait information, participant samples, and variant interpretations are all shared in the public domain-we invite others to review our results using our participant samples and contribute to our interpretations. We offer our public resource and methods to further personalized medical research.

AB During Mycobacterium tuberculosis infection, a population of bacteria likely becomes refractory to antibiotic killing in the absence of genotypic resistance, making treatment challenging. We describe an in vitro model capable of yielding a phenotypically antibiotic-tolerant subpopulation of cells, often called persisters, within populations of Mycobacterium smegmatis and M. tuberculosis. We find that persisters are distinct from the larger antibiotic-susceptible population, as a small drop in dissolved oxygen (DO) saturation (20%) allows for their survival in the face of bactericidal antibiotics. In contrast, if high levels of DO are maintained, all cells succumb, sterilizing the culture. With increasing evidence that bactericidal antibiotics induce cell death through the production of reactive oxygen species (ROS), we hypothesized that the drop in DO decreases the concentration of ROS, thereby facilitating persister survival, and maintenance of high DO yields sufficient ROS to kill persisters. Consistent with this hypothesis, the hydroxylradical scavenger thiourea, when added to M. smegmatis cultures maintained at high DO levels, rescues the persister population. Conversely, the antibiotic clofazimine, which increases ROS via an NADH-dependent redox cycling pathway, successfully eradicates the persister population. Recent work suggests that environmentally induced antibiotic tolerance of bulk populations may result from enhanced antioxidant capabilities. We now show that the small persister subpopulation within a larger antibiotic-susceptible population also shows differential susceptibility to antibiotic-induced hydroxyl radicals. Furthermore, we show that stimulating ROS production can eradicate persisters, thus providing a potential strategy to managing persistent infections.

AB As with other cognitive phenomena that are based upon the capacity limitations of visual processing, it is thought that attentional blink (AB) cannot be eliminated, even after extensive training. We report in this paper that just 1 h of specific attentional training can completely eliminate AB, and that this effect is robust enough to persist for a few months after training. Results of subsequent behavioral and functional magnetic resonance imaging (fMRI) experiments indicate that this learning effect is associated with improvements in temporal resolution, which are mainly due to processing in the prefrontal areas. Contrary to prior wisdom, we conclude that capacity limitations can be overcome by short-term training.

AB Objectives This study sought to investigate whether pregnancy-associated plasma protein-A (PAPP-A) is useful for risk assessment in non-ST-segment elevation acute coronary syndrome (NSTE-ACS).
Background PAPP-A is a high molecular weight, zinc-binding metalloproteinase that is associated with vulnerable plaque and may be a predictor of cardiovascular disease and mortality.
Methods We measured PAPP-A at baseline in 3,782 patients with non NSTE-ACS randomized to ranolazine or placebo in the MERLIN-TIMI 36 (Metabolic Efficiency With Ranolazine for Less Ischemia in Non-ST Elevation Acute Coronary Syndromes) trial and followed for an average of 1 year. A cut point of 6.0 mu IU/ml was chosen from pilot work in this cohort.
Results PAPP-A >6.0 mu IU/ml at presentation was associated with higher rates of cardiovascular death (CVD) or myocardial infarction (MI) at 30 days (7.4% vs. 3.7%, hazard ratio [HR]: 2.01; 95% confidence interval [CI]: 1.43 to 2.82; p < 0.001) and at 1 year (14.9% vs. 9.7%, HR: 1.63; 95% CI: 1.29 to 2.05; p < 0.001). PAPP-A was also associated with higher rates of CVD (HR: 1.94; 95% CI: 1.07 to 3.52, p < 0.027) and myocardial infarction (HR: 1.82; 95% CI: 1.22 to 2.71, p = 0.003) individually at 30 days. There was no difference in the risk associated with PAPP-A stratified by baseline cardiac troponin I [Accu-TnI >0.04 mu g/l], p interaction = 0.87). After adjustment for cardiac troponin I, ST-segment deviation, age, sex, diabetes, smoking, hypertension, and coronary artery disease, PAPP-A was independently associated with CVD/myocardial infarction at 30 days (adjusted HR: 1.62, 95% CI: 1.15 to 2.29; p = 0.006) and 1 year (adjusted HR: 1.35, 95% CI: 1.07 to 1.71; p = 0.012). PAPP-A also improved the net reclassification for CVD/MI (p = 0.003). There was no significant interaction with ranolazine.
Conclusions PAPP-A was independently associated with recurrent cardiovascular events in patients with NSTE-ACS. This finding supports PAPP-A as a candidate prognostic marker in patients with ACS and supports investigation of its therapeutic implications.

AB Background: MicroRNAs (miRNAs) are nucleic acid regulators of many human mRNAs, and are associated with many tumorigenic processes. miRNA expression levels have been used in profiling studies, but some evidence suggests that expression levels do not fully capture miRNA regulatory activity. In this study we integrate multiple gene expression datasets to determine miRNA activity patterns associated with cancer phenotypes and oncogenic pathways in mesenchymal tumors - a very heterogeneous class of malignancies.
Results: Using a computational method, we identified differentially activated miRNAs between 77 normal tissue specimens and 135 sarcomas and we validated many of these findings with microarray interrogation of an independent, paraffin-based cohort of 18 tumors. We also showed that miRNA activity is imperfectly correlated with miRNA expression levels. Using next-generation miRNA sequencing we identified potential base sequence alterations which may explain differential activity. We then analyzed miRNA activity changes related to the RAS-pathway and found 21 miRNAs that switch from silenced to activated status in parallel with RAS activation. Importantly, nearly half of these 21 miRNAs were predicted to regulate integral parts of the miRNA processing machinery, and our gene expression analysis revealed significant reductions of these transcripts in RAS-active tumors. These results suggest an association between RAS signaling and miRNA processing in which miRNAs may attenuate their own biogenesis.
Conclusions: Our study represents the first gene expression-based investigation of miRNA regulatory activity in human sarcomas, and our findings indicate that miRNA activity patterns derived from integrated transcriptomic data are reproducible and biologically informative in cancer. We identified an association between RAS signaling and miRNA processing, and demonstrated sequence alterations as plausible causes for differential miRNA activity. Finally, our study highlights the value of systems level integrative miRNA/mRNA assessment with high-throughput genomic data, and the applicability of paraffin-tissue-derived RNA for validation of novel findings.

AB Background: Sudden cardiac death (SCD) accounts for up to half of cardiac mortality. The risk of SCD is heritable but the underlying genetic variants are largely unknown. We investigated whether common genetic variants predisposing to arrhythmia or related electrocardiographic phenotypes, including QT-interval prolongation, are associated with increased risk of SCD.
Methodology/Principal Findings: We studied the association between 28 candidate SNPs and SCD in a meta-analysis of four population cohorts (FINRISK 1992, 1997, 2002 and Health 2000, n = 27,629) and two forensic autopsy series (The Helsinki Sudden Death Study and The Tampere Autopsy Study, n = 694). We also studied the association between established cardiovascular risk factors and SCD. Causes of death were reviewed using registry-based health and autopsy data. Cox regression and logistic regression models were adjusted for age, sex, and geographic region. The total number of SCDs was 716. Two novel SNPs were associated with SCD: SCN5A rs41312391 (relative risk [RR] 1.27 per minor T allele, 95% CI 1.11-1.45, P = 3.4x10(-4)) and rs2200733 in 4q25 (RR 1.28 per minor T allele, 95% CI 1.11-1.48, P = 7.9x10(-4)). We also replicated the associations for 9p21 (rs2383207, RR 1.13 per G allele, 95% CI 1.01-1.26, P = 0.036), as well as for male sex, systolic blood pressure, diabetes, cigarette smoking, low physical activity, coronary heart disease, and digoxin use (P < 0.05).
Conclusions/Significance: Two novel genetic variants, one in the cardiac sodium channel gene SCN5A and another at 4q25 previously associated with atrial fibrillation, are associated with SCD.

AB Soluble cytokine receptors are normal constituents of body fluids that regulate peripheral cytokine and lymphoid activity and whose levels are increased in states of immune activation. Soluble interleukin-6 receptor (sIL-6R) levels positively correlate with disease progression in some autoimmune conditions and psychiatric disorders. Particularly strong links between levels of sIL-6R and the severity of psychotic symptoms occur in schizophrenia, raising the possibility that sIL-6R is involved in this disease. However, there is no evidence that peripheral sIL-6R induces relevant behavioral disturbances. We showed that single subcutaneous injections of sIL-6R (0-1 mu g), stimulated novelty stress-induced exploratory motor behaviors in male Balb/c mice within 20-40-min of injection. A progressive increase in vertical stereotypies was observed 40-80 min post injection, persisting for the remainder of the test session. Paralleling these stimulant-like effects, sIL-6R pretreatment significantly enhanced stereotypy scores following challenge with GBR 12909. We found that peripherally administered sIL-6R crossed the blood-brain barrier, localizing in brain regions associated with cortico-striatal-thalamo-cortical (CSTC) circuits, which are putative neuroanatomical substrates of disorders associated with repetitive stereotypies. Peripherally administered sIL-6R co-localized with gp130, a transmembrane protein involved in IL-6 trans-signaling, in the nucleus accumbens, caudate-putamen, motor and infralimbic cortices, and thalamic nuclei, but not with gp130 in the ventral tegmental area, substantia nigra, or sensorimotor cortex,. The results suggest that peripheral sIL-6R can act as a neuroimmune messenger, crossing the blood brain barrier (BBB) to selectively target CSTC circuits rich in IL-6 trans-signaling protein, and inducing repetitive stereotypies. As such sIL-6R may represent a novel therapeutic agent for relevant psychiatric disorders.

INTERFERON-GAMMA; TNF GENE; IN-VIVO; NUCLEAR FACTOR
AB In T cells, the transcription factor nuclear factor of activated T cells p (NFATp) is a key regulator of the cytokine genes tumor necrosis factor (TNF) and interferon-gamma (IFN-gamma). Here, we show that NFATp-deficient (NFATp(-/-)) mice have a dramatic and highly significant increase in mortality after Mycobacterium tuberculosis (MTb) infection as compared to mortality of control animals after MTb infection. Animals deficient in NFATp have significantly impaired levels of TNF and IFN-gamma transcription and protein expression in naive or total CD4(+) T cells, but display wild-type levels of TNF mRNA or protein from MTb-stimulated dendritic cells (DC). The rapid mortality and disease severity observed in MTb-infected NFATp(-/-) mice is associated with dysregulated production of TNF and IFN-gamma in the lungs, as well as with increased levels of TNF, in their serum. Furthermore, global blocking of TNF production by injection of a TNF neutralizaing agent at 6 weeks, but not 12 weeks, post-MTb-infection further decreased the survival rate of both wild-type and NFATp(-/-) mice, indicating an early role for TNF derived from cells from the monocyte lineage in containment of infection. These results thus demonstrate that NFATp plays a critical role in immune containment of TB disease in vivo, through the NFATp-dependent expression of TNF and IFN-gamma in T cells.

TI Frailty, Dialysis Initiation, and Mortality in End-Stage Renal Disease
SO ARCHIVES OF INTERNAL MEDICINE
LA English
DT Article
ID PHYSICAL-ACTIVITY; HEMODIALYSIS; HARMFUL; ADULTS; OLDER
AB Background: In light of the recent trend toward earlier dialysis initiation and its association with mortality among patients with end-stage renal disease, we hypothesized that frailty is associated with higher estimated glomerular filtration rate (eGFR) at dialysis start and may confound the relation between earlier dialysis initiation and mortality.
Methods: We examined frailty among participants of the Comprehensive Dialysis Study (CDS), a special study of the US Renal Data System, which enrolled incident patients from September 1, 2005, through June 1, 2007. Patients were followed for vital status through September 30, 2009, and for time to first hospitalization through December 31, 2008. We used multivariate logistic regression to model the association of frailty with eGFR at dialysis start and proportional hazards regression to assess the outcomes of death or hospitalization.
Results: Among 1576 CDS participants included, the prevalence of frailty was 73%. In multivariate analysis, higher eGFR at dialysis initiation was associated with higher odds of frailty (odds ratio [OR], 1.44 [95% CI, 1.23-1.68] per 5 mL/min/1.73 m(2); P<.001). Frailty was independently associated with mortality (hazard ratio [HR], 1.57 [95% CI, 1.25-1.97]; P<.001) and time to first hospitalization (HR, 1.26 [95% CI, 1.09-1.45]; P < .001). While higher eGFR at dialysis initiation was associated with mortality (HR, 1.12 [95% CI, 1.02-1.23] per 5 mL/min/1.73 m2; P=.02), the association was no longer statistically significant after frailty was accounted for (HR, 1.08 [95% CI, 0.98-1.19] per 5 mL/min/1.73 m(2); P=.11).
Conclusions: Frailty is extremely common among patients starting dialysis in the United States and is associated with higher eGFR at dialysis initiation. Recognition of signs and symptoms of frailty by clinicians may prompt earlier initiation of dialysis and may explain, at least in part, the well-described association between eGFR at dialysis initiation and mortality.

ASSOCIATION; IMPAIRMENT; MORTALITY; LIFE
AB Background: Loneliness is a common source of distress, suffering, and impaired quality of life in older persons. We examined the relationship between loneliness, functional decline, and death in adults older than 60 years in the United States.
Methods: This is a longitudinal cohort study of 1604 participants in the psychosocial module of the Health and Retirement Study, a nationally representative study of older persons. Baseline assessment was in 2002 and follow-up assessments occurred every 2 years until 2008. Subjects were asked if they (1) feel left out, (2) feel isolated, or (3) lack companionship. Subjects were categorized as not lonely if they responded hardly ever to all 3 questions and lonely if they responded some of the time or often to any of the 3 questions. The primary outcomes were time to death over 6 years and functional decline over 6 years on the following 4 measures: difficulty on an increased number of activities of daily living (ADL), difficulty in an increased number of upper extremity tasks, decline in mobility, or increased difficulty in stair climbing. Multivariate analyses adjusted for demographic variables, socioeconomic status, living situation, depression, and various medical conditions.
Results: The mean age of subjects was 71 years. Fifty-nine percent were women; 81% were white, 11%, black, and 6%, Hispanic; and 18% lived alone. Among the elderly participants, 43% reported feeling lonely. Loneliness was associated with all outcome measures. Lonely subjects were more likely to experience decline in ADL (24.8% vs 12.5%; adjusted risk ratio [RR], 1.59; 95% CI, 1.23-2.07); develop difficulties with upper extremity tasks (41.5% vs 28.3%; adjusted RR, 1.28; 95% CI, 1.08-1.52); experience decline in mobility (38.1% vs 29.4%; adjusted RR, 1.18; 95% CI, 0.99-1.41); or experience difficulty in climbing (40.8% vs 27.9%; adjusted RR, 1.31; 95% CI, 1.10-1.57). Loneliness was associated with an increased risk of death (22.8% vs 14.2%; adjusted HR, 1.45; 95% CI, 1.11-1.88).
Conclusion: Among participants who were older than 60 years, loneliness was a predictor of functional decline and death.

AB Background: Living alone, a proxy for social support, has been inconsistently linked with cardiovascular risk.
Methods: We investigated whether living alone was associated with increased mortality and cardiovascular risk in the global REduction of Atherothrombosis for Continued Health (REACH) Registry. Stable outpatients at risk of or with atherothrombosis were recruited from December 1, 2003, through December 31, 2004, and followed up to 4 years for cardiovascular events. Events were examined by living arrangement with risk adjustment for age, sex, clinical risk factors, therapy, preexisting vascular disease, and sociodemographic factors. Effect modification was tested by age, sex, employment, ethnicity, education, and geography.
Results: Among the 44 573 REACH participants, 8594 (19%) were living alone. Living alone was associated with higher 4-year mortality (14.1% vs 11.1%) and cardiovascular death (8.6% vs 6.8%; log-rank P<.01 for both comparisons); however, there was significant effect modification by age (P value for interaction =.03). Specifically, among younger participants, living alone compared with those living with others was associated with higher mortality (age 45-65 years: 7.7% vs 5.7%; adjusted hazard ratio [HR], 1.24 195% CI, 1.01-1.511; age 66-80 years: 13.2% vs 12.3%; adjusted HR, 1.12 [95% CI, 1.01-1.261), but this was not observed among older participants (age > 80 years: 24.6% vs 28.4%; adjusted HR, 0.92 [95% CI, 0.79-1.061). A similar trend was observed for the risk of cardiovascular death.
Conclusions: In an international outpatient population with atherothrombosis aged 45 years or older, living alone was associated with increased mortality among all but the most elderly patients, although this observation warrants confirmation.

AB AIM: To investigate the clinicopathologic features which predict surgical overall survival in patients with proximal gastric carcinoma involving the esophagus (PGCE).
METHODS: Electronic pathology database established in the Department of Pathology of the Nanjing Drum Tower Hospital was searched for consecutive resection cases of proximal gastric carcinoma over the period from May 2004 through July 2009. Each retrieved pathology report was reviewed and the cases with tumors crossing the gastroesophageal junction line were selected as PGCE. Each tumor was re-staged, following the guidelines on esophageal adenocarcinoma, according to the 7th edition of the American Joint Commission on Cancer Staging Manual. All histology slides were studied along with the pathology report for a retrospective analysis of 13 clinicopathologic features, i.e., age, gender, Helicobacter pylori (H. pylori) infection, surgical modality, Siewert type, tumor Bormann's type, size, differentiation, histology type, surgical margin, lymphovascular and perineural invasion, and pathologic stage in relation to survival after surgical resection. Prognostic factors for overall survival were assessed with uni- and multi-variate analyses.
RESULTS: Patients' mean age was 65 years (range: 47-90 years). The male: female ratio was 3.3. The 1-, 3- and 5-year overall survival rates were 87%, 61% and 32%, respectively. By univariate analysis, age, male gender, H. pylori, tumor Bormann's type, size, histology type, surgical modality, positive surgical margin, lymphovascular invasion, and pT stage were not predictive for overall survival; in contrast, perineural invasion (P = 0.003), poor differentiation (P = 0.0003), > 15 total lymph nodes retrieved (P = 0.008), positive lymph nodes (P = 0.001), and distant metastasis (P = 0.005) predicted poor post-operative overall survival. Celiac axis nodal metastasis was associated with significantly worse overall survival (P = 0.007). By multivariate analysis, >= 16 positive nodes (P = 0.018), lymph node ratio > 0.2 (P = 0.003), and overall pathologic stage (P = 0.002) were independent predictors for poor overall survival after resection.
CONCLUSION: Patients with PGCE showed worse overall survival in elderly, high nodal burden and advanced pathologic stage. This cancer may be more accurately staged as gastric, than esophageal, cancer. (c) 2012 Baishideng. All rights reserved.

AB Sensing and enumeration of specific types of circulating cells in small animals is an important problem in many areas of biomedical research. Microscopy-based fluorescence in vivo flow cytometry methods have been developed previously, but these are typically limited to sampling of very small blood volumes, so that very rare circulating cells may escape detection. Recently, we described the development of a 'diffuse fluorescence flow cytometer' (DFFC) that allows sampling of much larger blood vessels and therefore circulating blood volumes in the hindlimb, forelimb or tail of a mouse. In this work, we extend this concept by developing and validating a method to tomographically localize circulating fluorescently labeled cells in the cross section of a tissue simulating optical flow phantom and mouse limb. This was achieved using two modulated light sources and an array of six fiber-coupled detectors that allowed rapid, high-sensitivity acquisition of full tomographic data sets at 10 Hz. These were reconstructed into two-dimensional cross-sectional images using Monte Carlo models of light propagation and the randomized algebraic reconstruction technique. We were able to obtain continuous images of moving cells in the sample cross section with 0.5 mm accuracy or better. We first demonstrated this concept in limb-mimicking optical flow photons with up to four flow channels, and then in the tails of mice with fluorescently labeled multiple myeloma cells. This approach increases the overall diagnostic utility of our DFFC instrument.

AB Background: Limited financial and geographic access to primary care can adversely influence chronic disease outcomes. We examined variation in awareness, treatment, and control of hypertension, diabetes, and hyperlipidemia according to both geographic and financial access to care.
Methods: We analyzed data on 17,458 participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study with either hypertension, hyperlipidemia, or diabetes and living in either complete Health Professional Shortage Area (HPSA) counties or non-HPSA counties in the U. S. All analyses were stratified by insurance status and adjusted for sociodemographics and health behaviors.
Results: 2,261 residents lived in HPSA counties and 15,197 in non-HPSA counties. Among the uninsured, HPSA residents had higher awareness of both hypertension (adjusted OR 2.30, 95% CI 1.08, 4.89) and hyperlipidemia (adjusted OR 1.50, 95% CI 1.01, 2.22) compared to non-HPSA residents. Also among the uninsured, HPSA residents with hypertension had lower blood pressure control (adjusted OR 0.45, 95% CI 0.29, 0.71) compared with non-HPSA residents. Similar differences in awareness and control according to HPSA residence were absent among the insured.
Conclusions: Despite similar or higher awareness of some chronic diseases, uninsured HPSA residents may achieve control of hypertension at lower rates compared to uninsured non-HPSA residents. Federal allocations in HPSAs should target improved quality of care as well as increasing the number of available physicians.

AB A poorly understood aspect of DNA repair proteins is their ability to identify exceedingly rare sites of damage embedded in a large excess of nearly identical undamaged DNA, while catalyzing repair only at the damaged sites. Progress toward understanding this problem has been made by comparing the structures and biochemical behavior of these enzymes when they are presented with either a target lesion or a corresponding undamaged nucleobase. Trapping and analyzing such DNA-protein complexes is particularly difficult in the case of base extrusion DNA repair proteins because of the complexity of the repair reaction, which involves extrusion of the target base from DNA followed by its insertion into the active site where glycosidic bond cleavage is catalyzed. Here we report the structure of a human 8-oxoguanine (oxoG) DNA glycosylase, hOGG1, in which a normal guanine from DNA has been forcibly inserted into the enzyme active site. Although the interactions of the nucleobase with the active site are only subtly different for G versus oxoG, hOGG1 fails to catalyze excision of the normal nucleobase. This study demonstrates that even if hOGG1 mistakenly inserts a normal base into its active site, the enzyme can still reject it on the basis of catalytic incompatibility.

TI Overall Survival Benefit With Lapatinib in Combination With Trastuzumab
for Patients With Human Epidermal Growth Factor Receptor 2-Positive
Metastatic Breast Cancer: Final Results From the EGF104900 Study
SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID ESTROGEN-RECEPTOR; RANDOMIZED-TRIAL; ERBB RECEPTORS; PROGRESSION; WOMEN;
PLUS; AMPLIFICATION; PACLITAXEL; ONCOGENE; THERAPY
AB Purpose
Phase III EGF104900 data demonstrated that lapatinib plus trastuzumab significantly improved progression-free survival (PFS) and clinical benefit rate versus lapatinib monotherapy, offering a chemotherapy-free option for patients with heavily pretreated human epidermal growth factor receptor 2 (HER2) -positive metastatic breast cancer (MBC). Final planned overall survival (OS) analysis from EGF104900 is reported here.
Patients and Methods
Patients with HER2-positive MBC whose disease progressed during prior trastuzumab-based therapies were randomly assigned to receive lapatinib monotherapy or lapatinib in combination with trastuzumab. OS and updated PFS data are presented using Kaplan-Meier curves and log-rank tests stratified for hormone receptor and visceral disease status. Subgroup analyses were conducted to identify characteristics of patients deriving the greatest clinical benefit.
Results
In this updated final analysis of all patients randomly assigned with strata (n = 291), lapatinib plus trastuzumab continued to show superiority to lapatinib monotherapy in PFS (hazard ratio [HR], 0.74; 95% CI, 0.58 to 0.94; P = .011) and offered significant OS benefit (HR, 0.74; 95% CI, 0.57 to 0.97; P = .026). Improvements in absolute OS rates were 10% at 6 months and 15% at 12 months in the combination arm compared with the monotherapy arm. Multiple baseline factors, including Eastern Cooperative Oncology Group performance status of 0, nonvisceral disease, < three metastatic sites, and less time from initial diagnosis until random assignment, were associated with improved OS. Incidence of adverse events was consistent with previously reported rates.
Conclusion
These data demonstrated a significant 4.5-month median OS advantage with the lapatinib and trastuzumab combination and support dual HER2 blockade in patients with heavily pretreated HER2-positive MBC.

TI TBCRC 001: Randomized Phase II Study of Cetuximab in Combination With

SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID MOLECULAR CHARACTERIZATION; EXPRESSION PROFILES; SUBTYPES; TUMORS;
CHEMOTHERAPY; PORTRAITS; CARCINOMA; PATTERNS; CAROLINA; SURVIVAL
AB Purpose
Epidermal growth factor receptor (EGFR) is a targetable receptor frequently overexpressed in basal-like breast cancer, which comprises most triple-negative breast cancers (TNBCs), the only subtype without established targeted therapy.
Patients and Methods
In this randomized phase II trial, patients with metastatic TNBC received anti-EGFR antibody cetuximab (400 mg/m(2) load then 250 mg/m(2) per week intravenously [IV]) alone, with carboplatin (area under the curve of 2, once per week IV) added after progression or as concomitant therapy from the beginning. Response rate (RR) was the primary end point; others included time to progression (TTP), overall survival (OS), and toxicity. Embedded correlative studies included molecular subtyping on archival tissue. Fresh tumor tissue before and after 7 to 14 days of therapy was used for microarray analyses exploring EGFR pathway activity and inhibition.
Results
In 102 patients with TNBC, RRs were 6% (two of 31) to cetuximab and 16% (four of 25) to cetuximab plus carboplatin after progression. RR to those treated from the beginning with cetuximab plus carboplatin was 17% (12 of 71); 31% of patients responded or had prolonged disease stabilization. The cetuximab plus carboplatin regimen was well tolerated, but both TTP and OS were short at 2.1 months (95% CI, 1.8 to 5.5 months) and 10.4 months (95% CI, 7.7 to 13.1 months), respectively. Of 73 patients with archival tissue for analysis, 74% had basal-like molecular subtype. Sixteen patients had tumor biopsies before and 1 week after therapy; genomic patterns of the EGFR pathway showed activation in 13 and inhibition by therapy in five.
Conclusion
Despite strong preclinical data, combination cetuximab plus carboplatin in metastatic TNBC produced responses in fewer than 20% of patients. EGFR pathway analysis showed that most TNBCs involved activation. However, cetuximab blocked expression of the EGFR pathway in only a minority, suggesting that most had alternate mechanisms for pathway activation.

TI Effect of Adjuvant Chemotherapy on Survival of Patients With Stage III
Colon Cancer Diagnosed After Age 75 Years
SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID ELDERLY-PATIENTS; POOLED ANALYSIS; COMORBIDITY INDEX; COLORECTAL-CANCER;
NSABP C-07; FLUOROURACIL; OXALIPLATIN; LEUCOVORIN; TRIAL; POPULATION
AB Purpose
Few patients 75 years of age and older participate in clinical trials, thus whether adjuvant chemotherapy for stage III colon cancer (CC) benefits this group is unknown.
Methods
A total of 5,489 patients >= 75 years of age with resected stage III CC, diagnosed between 2004 and 2007, were selected from four data sets containing demographic, stage, treatment, and survival information. These data sets included SEER-Medicare, a linkage between the New York State Cancer Registry (NYSCR) and its Medicare programs, and prospective cohort studies Cancer Care Outcomes Research and Surveillance Consortium (CanCORS) and the National Comprehensive Cancer Network. Data sets were analyzed in parallel using covariate adjusted and propensity score (PS) matched proportional hazards models to evaluate the effect of treatment on survival. PS trimming was used to mitigate the effects of selection bias.
Results
Use of adjuvant therapy declined with age and comorbidity. Chemotherapy receipt was associated with a survival benefit of comparable magnitude to clinical trials results (SEER-Medicare PS-matched mortality, hazard ratio [HR], 0.60; 95% CI, 0.53 to 0.68). The incremental benefit of oxaliplatin over non-oxaliplatin-containing regimens was also of similar magnitude to clinical trial results (SEER-Medicare, HR, 0.84; 95% CI, 0.69 to 1.04; NYSCR-Medicare, HR, 0.82, 95% CI, 0.51 to 1.33) in two of three examined data sources. However, statistical significance was inconsistent. The beneficial effect of chemotherapy and oxaliplatin did not seem solely attributable to confounding.
Conclusion
The noninvestigational experience suggests patients with stage III CC >= 75 years of age may anticipate a survival benefit from adjuvant chemotherapy. Oxaliplatin offers no more than a small incremental benefit. Use of adjuvant chemotherapy after the age of 75 years merits consideration in discussions that weigh individual risks and preferences.

Group Phase I/II Study
SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID BRAIN-TUMORS; CHEMOTHERAPY; RADIATION; CHILDHOOD; TRIAL; SENSITIVITY;
CISPLATIN
AB Purpose
We evaluated the feasibility of administering carboplatin as a radiosensitizer during craniospinal radiation therapy (CSRT) to patients with high-risk medulloblastomas (MBs) and supratentorial primitive neuroectodermal tumors, and we report the outcome in the subset with metastatic (M+) MB.
Patients and Methods
After surgery, patients received 36 Gy CSRT with boosts to sites of disease. During radiation, patients received 15 to 30 doses of carboplatin (30-45 mg/m(2)/dose), along with vincristine (VCR) once per week for 6 weeks. Patients on regimen A received 6 months of maintenance chemotherapy (MC) with cyclophosphamide and VCR. Once the recommended phase II dose (RP2D) of carboplatin was determined, cisplatin was added to the MC (regimen B).
Results
In all, 161 eligible patients (median age, 8.7 years; range, 3.1 to 21.6 years) were enrolled. Myelosuppression was dose limiting and 35 mg/m(2)/dose x 30 was determined to be the RP2D of carboplatin. Twenty-nine (36%) of 81 patients with M+ MB had diffuse anaplasia. Four patients were taken off study within 11 months of completing radiotherapy for presumed metastatic progression and are long-term survivors following palliative chemotherapy. Excluding these four patients, 5-year overall survival +/- SE and progression-free survival +/- SE for M+ patients treated at the RP2D on regimen A was 82% +/- 9% and 71% +/- 11% versus 68% +/- 10% and 59% +/- 10% on regimen B (P = .36). There was no difference in survival by M stage. Anaplasia was a negative predictor of outcome.
Conclusion
The use of carboplatin as a radiosensitizer is a promising strategy for patients with M+ MB. Early progression should be confirmed by biopsy.

TI BRCA Mutation Frequency and Patterns of Treatment Response in BRCA
Mutation-Positive Women With Ovarian Cancer: A Report From the
Australian Ovarian Cancer Study Group

FEATURES; TUMORS
AB Purpose
The frequency of BRCA1 and BRCA2 germ-line mutations in women with ovarian cancer is unclear; reports vary from 3% to 27%. The impact of germ-line mutation on response requires further investigation to understand its impact on treatment planning and clinical trial design.
Patients and Methods
Women with nonmucinous ovarian carcinoma (n = 1,001) enrolled onto a population-based, case-control study were screened for point mutations and large deletions in both genes. Survival outcomes and responses to multiple lines of chemotherapy were assessed.
Results
Germ-line mutations were found in 14.1% of patients overall, including 16.6% of serous cancer patients (high-grade serous, 22.6%); 44% had no reported family history of breast or ovarian cancer. Patients carrying germ-line mutations had improved rates of progression-free and overall survival. In the relapse setting, patients carrying mutations more frequently responded to both platin- and nonplatin-based regimens than mutation-negative patients, even in patients with early relapse after primary treatment. Mutation-negative patients who responded to multiple cycles of platin- based treatment were more likely to carry somatic BRCA1/2 mutations.
Conclusion
BRCA mutation status has a major influence on survival in ovarian cancer patients and should be an additional stratification factor in clinical trials. Treatment outcomes in BRCA1/2 carriers challenge conventional definitions of platin resistance, and mutation status may be able to contribute to decision making and systemic therapy selection in the relapse setting. Our data, together with the advent of poly(ADP-ribose) polymerase inhibitor trials, supports the recommendation that germ-line BRCA1/2 testing should be offered to all women diagnosed with nonmucinous, ovarian carcinoma, regardless of family history.

AB Despite recent insights into melanoma genetics, systematic surveys for driver mutations are challenged by an abundance of passenger mutations caused by carcinogenic UV light exposure. We developed a permutation-based framework to address this challenge, employing mutation data from intronic sequences to control for passenger mutational load on a per gene basis. Analysis of large-scale melanoma exome data by this approach discovered six novel melanoma genes (PPP6C, RAC1, SNX31, TACC1, STK19, and ARID2), three of which-RAC1, PPP6C, and STK19-harbored recurrent and potentially targetable mutations. Integration with chromosomal copy number data contextualized the landscape of driver mutations, providing oncogenic insights in BRAF- and NRAS-driven melanoma as well as those without known NRAS/BRAF mutations. The landscape also clarified a mutational basis for RB and p53 pathway deregulation in this malignancy. Finally, the spectrum of driver mutations provided unequivocal genomic evidence for a direct mutagenic role of UV light in melanoma pathogenesis.

AB RIP1 and RIP3 kinases are central players in TNF-induced programmed necrosis. Here, we report that the RIP homotypic interaction motifs (RHIMs) of RIP1 and RIP3 mediate the assembly of heterodimeric filamentous structures. The fibrils exhibit classical characteristics of beta-amyloids, as shown by Thioflavin T (ThT) and Congo red (CR) binding, circular dichroism, infrared spectroscopy, X-ray diffraction, and solid-state NMR. Structured amyloid cores are mapped in RIP1 and RIP3 that are flanked by regions of mobility. The endogenous RIP1/RIP3 complex isolated from necrotic cells binds ThT, is ultrastable, and has a fibrillar core structure, whereas necrosis is partially inhibited by ThT, CR, and another amyloid dye, HBX. Mutations in the RHIMs of RIP1 and RIP3 that are defective in the interaction compromise cluster formation, kinase activation, and programmed necrosis in vivo. The current study provides insight into the structural changes that occur when RIP kinases are triggered to execute different signaling outcomes and expands the realm of amyloids to complex formation and signaling.

AB Brown fat generates heat via the mitochondrial uncoupling protein UCP1, defending against hypothermia and obesity. Recent data suggest that there are two distinct types of brown fat: classical brown fat derived from a myf-5 cellular lineage and UCP1-positive cells that emerge in white fat from a non-myf-5 lineage. Here, we report the isolation of "beige" cells from murine white fat depots. Beige cells resemble white fat cells in having extremely low basal expression of UCP1, but, like classical brown fat, they respond to cyclic AMP stimulation with high UCP1 expression and respiration rates. Beige cells have a gene expression pattern distinct from either white or brown fat and are preferentially sensitive to the polypeptide hormone irisin. Finally, we provide evidence that previously identified brown fat deposits in adult humans are composed of beige adipocytes.

TI Learning That Circumcision Is Protective against HIV: Risk Compensation
among Men and Women in Cape Town, South Africa
SO PLOS ONE
LA English
DT Article
ID RANDOMIZED CONTROLLED-TRIAL; PREVENTION; INFECTION; KENYA; BEHAVIOR;
KISUMU; UGANDA; RAKAI
AB Objectives: We examined whether knowledge of the HIV-protective benefits of male circumcision (MC) led to risk compensating behavior in a traditionally circumcising population in South Africa. We extend the current literature by examining risk compensation among women, which has hitherto been unexplored.
Methods: We used data on Xhosa men and women from the 2009 Cape Area Panel Study. Respondents were asked if they had heard that MC reduces a man's risk of contracting HIV, about their perceived risk of contracting HIV, and condom use. For each gender group we assessed whether risk perception and condom use differed by knowledge of the protective benefits of MC using bivariate and then multivariate models controlling for demographic characteristics, HIV knowledge/beliefs, and previous sexual behaviors. In a further check for confounding, we used data from the 2005 wave to assess whether individuals who would eventually become informed about the protective benefits of circumcision were already different in terms of HIV risk perception and condom use.
Results: 34% of men (n = 453) and 27% of women (n = 690) had heard that circumcision reduces a man's risk of HIV infection. Informed men perceived slightly higher risk of contracting HIV and were more likely to use condoms at last sex (p < 0.10). Informed women perceived lower HIV risk (p < 0.05), were less likely to use condoms both at last sex (p < 0.10) and more generally (p < 0.01), and more likely to forego condoms with partners of positive or unknown serostatus (p < 0.01). The results were robust to covariate adjustment, excluding people living with HIV, and accounting for risk perceptions and condom use in 2005.
Conclusions: We find evidence consistent with risk compensation among women but not men. Further attention should be paid to the role of new information regarding MC, and drivers of HIV risk more broadly, in modulating sexual behavior among women.

TI Expression of CD30 in patients with acute graft-versus-host disease

AB Acute GVHD (aGVHD) remains a major source of morbidity after allogeneic hematopoietic cell transplantation. CD30 is a cell-surface protein expressed on certain activated T cells. We analyzed CD30 expression on peripheral blood T-cell subsets and soluble CD30 levels in 26 patients at the time of presentation of aGVHD, before the initiation of treatment, compared with 27 patients after hematopoietic cell transplantation without aGVHD (NONE). Analysis by flow cytometry showed that patients with aGVHD had a greater percentage of CD30 expressing CD8(+) T cells with the difference especially pronounced in the central memory subset (CD8(+)CD45RO(+)CD62L(+)): GVHD median 12.4% (range, 0.8%-33.4%) versus NONE 2.1% (0.7%, 17.5%), P < .001. There were similar levels of CD30 expression in naive T cells, CD4(+) T cells, and regulatory (CD4+CD127(low)CD25(+)) T cells. Plasma levels of soluble CD30 were significantly greater in patients with GVHD: median 61.7 ng/mL (range, 9.8-357.1 ng/mL) versus 17.4 (range, 3.7-142.4 ng/mL) in NONE (P < .001). Immunohistochemical analysis of affected intestinal tissue showed many CD30(+) infiltrating lymphocytes present. These results suggest that CD30 expression on CD8(+) T-cell subsets or plasma levels of soluble CD30 may be a potential biomarker for aGVHD. CD30 may also represent a target for novel therapeutic approaches for aGVHD. (Blood. 2012;120(3):691-696)

AB During progression of atherosclerosis, myeloid cells destabilize lipid-rich plaques in the arterial wall and cause their rupture, thus triggering myocardial infarction and stroke. Survivors of acute coronary syndromes have a high risk of recurrent events for unknown reasons. Here we show that the systemic response to ischaemic injury aggravates chronic atherosclerosis. After myocardial infarction or stroke, Apoe(-/-) mice developed larger atherosclerotic lesions with a more advanced morphology. This disease acceleration persisted over many weeks and was associated with markedly increased monocyte recruitment. Seeking the source of surplus monocytes in plaques, we found that myocardial infarction liberated haematopoietic stem and progenitor cells from bone marrow niches via sympathetic nervous system signalling. The progenitors then seeded the spleen, yielding a sustained boost in monocyte production. These observations provide new mechanistic insight into atherogenesis and provide a novel therapeutic opportunity to mitigate disease progression.

AB To characterize somatic alterations in colorectal carcinoma, we conducted a genome-scale analysis of 276 samples, analysing exome sequence, DNA copy number, promoter methylation and messenger RNA and microRNA expression. A subset of these samples (97) underwent low-depth-of-coverage whole-genome sequencing. In total, 16% of colorectal carcinomas were found to be hypermutated: three-quarters of these had the expected high microsatellite instability, usually with hypermethylation and MLH1 silencing, and one-quarter had somatic mismatch-repair gene and polymerase e (POLE) mutations. Excluding the hypermutated cancers, colon and rectum cancers were found to have considerably similar patterns of genomic alteration. Twenty-four genes were significantly mutated, and in addition to the expected APC, TP53, SMAD4, PIK3CA and KRAS mutations, we found frequent mutations in ARID1A, SOX9 and FAM123B. Recurrent copy-number alterations include potentially drug-targetable amplifications of ERBB2 and newly discovered amplification of IGF2. Recurrent chromosomal translocations include the fusion of NAV2 and WNT pathway member TCF7L1. Integrative analyses suggest new markers for aggressive colorectal carcinoma and an important role for MYC-directed transcriptional activation and repression.

AB Novel protein-coding genes can arise either through re-organization of pre-existing genes or de novo(1,2). Processes involving re-organization of pre-existing genes, notably after gene duplication, have been extensively described(1,2). In contrast, de novo gene birth remains poorly understood, mainly because translation of sequences devoid of genes, or 'non-genic' sequences, is expected to produce insignificant polypeptides rather than proteins with specific biological functions(1,3-6). Here we formalize an evolutionary model according to which functional genes evolve de novo through transitory proto-genes(4) generated by widespread translational activity in non-genic sequences. Testing this model at the genome scale in Saccharomyces cerevisiae, we detect translation of hundreds of short species-specific open reading frames (ORFs) located in non-genic sequences. These translation events seem to provide adaptive potential(7), as suggested by their differential regulation upon stress and by signatures of retention by natural selection. In line with our model, we establish that S. cerevisiae ORFs can be placed within an evolutionary continuum ranging from non-genic sequences to genes. We identify similar to 1,900 candidate proto-genes among S. cerevisiae ORFs and find that de novo gene birth from such a reservoir may be more prevalent than sporadic gene duplication. Our work illustrates that evolution exploits seemingly dispensable sequences to generate adaptive functional innovation.

AB BACKGROUND
The effectiveness of surgery versus observation for men with localized prostate cancer detected by means of prostate-specific antigen (PSA) testing is not known.
METHODS
From November 1994 through January 2002, we randomly assigned 731 men with localized prostate cancer (mean age, 67 years; median PSA value, 7.8 ng per milliliter) to radical prostatectomy or observation and followed them through January 2010. The primary outcome was all-cause mortality; the secondary outcome was prostate-cancer mortality.
RESULTS
During the median follow-up of 10.0 years, 171 of 364 men (47.0%) assigned to radical prostatectomy died, as compared with 183 of 367 (49.9%) assigned to observation (hazard ratio, 0.88; 95% confidence interval [CI], 0.71 to 1.08; P = 0.22; absolute risk reduction, 2.9 percentage points). Among men assigned to radical prostatectomy, 21 (5.8%) died from prostate cancer or treatment, as compared with 31 men (8.4%) assigned to observation (hazard ratio, 0.63; 95% CI, 0.36 to 1.09; P = 0.09; absolute risk reduction, 2.6 percentage points). The effect of treatment on all-cause and prostate-cancer mortality did not differ according to age, race, coexisting conditions, self-reported performance status, or histologic features of the tumor. Radical prostatectomy was associated with reduced all-cause mortality among men with a PSA value greater than 10 ng per milliliter (P = 0.04 for interaction) and possibly among those with intermediate-risk or high-risk tumors (P = 0.07 for interaction). Adverse events within 30 days after surgery occurred in 21.4% of men, including one death.
CONCLUSIONS
Among men with localized prostate cancer detected during the early era of PSA testing, radical prostatectomy did not significantly reduce all-cause or prostate-cancer mortality, as compared with observation, through at least 12 years of follow-up. Absolute differences were less than 3 percentage points. (Funded by the Department of Veterans Affairs Cooperative Studies Program and others; PIVOT ClinicalTrials.gov number, NCT00007644.)

AB BACKGROUND
For egg allergy, dietary avoidance is the only currently approved treatment. We evaluated oral immunotherapy using egg-white powder for the treatment of children with egg allergy.
METHODS
In this double-blind, randomized, placebo-controlled study, 55 children, 5 to 11 years of age, with egg allergy received oral immunotherapy (40 children) or placebo (15). Initial dose-escalation, build-up, and maintenance phases were followed by an oral food challenge with egg-white powder at 10 months and at 22 months. Children who successfully passed the challenge at 22 months discontinued oral immunotherapy and avoided all egg consumption for 4 to 6 weeks. At 24 months, these children underwent an oral food challenge with egg-white powder and a cooked egg to test for sustained unresponsiveness. Children who passed this challenge at 24 months were placed on a diet with ad libitum egg consumption and were evaluated for continuation of sustained unresponsiveness at 30 months and 36 months.
RESULTS
After 10 months of therapy, none of the children who received placebo and 55% of those who received oral immunotherapy passed the oral food challenge and were considered to be desensitized; after 22 months, 75% of children in the oral-immunotherapy group were desensitized. In the oral-immunotherapy group, 28% (11 of 40 children) passed the oral food challenge at 24 months and were considered to have sustained unresponsiveness. At 30 months and 36 months, all children who had passed the oral food challenge at 24 months were consuming egg. Of the immune markers measured, small wheal diameters on skin-prick testing and increases in egg-specific IgG4 antibody levels were associated with passing the oral food challenge at 24 months.
CONCLUSIONS
These results show that oral immunotherapy can desensitize a high proportion of children with egg allergy and induce sustained unresponsiveness in a clinically significant subset. (Funded by the National Institutes of Health; ClinicalTrials.gov number, NCT00461097.)

TI STARS Is Essential to Maintain Cardiac Development and Function In Vivo
via a SRF Pathway
SO PLOS ONE
LA English
DT Article
ID SERUM RESPONSE FACTOR; STRIATED-MUSCLE ACTIVATOR; HUMAN SKELETAL-MUSCLE;
GENE; EXPRESSION; ZEBRAFISH; TRANSCRIPTION; HYPERTROPHY; TARGETS
AB Background: STARS (STriated muscle Activator of Rho Signaling) is a sarcomeric protein expressed early in cardiac development that acts as an acute stress sensor for pathological remodeling. However the role of STARS in cardiac development and function is incompletely understood. Here, we investigated the role of STARS in heart development and function in the zebrafish model and in vitro.
Methodology and Principal Findings: Expression of zebrafish STARS (zSTARS) first occurs in the somites by the 16 somite stage [17 hours post fertilization (hpf)]. zSTARS is expressed in both chambers of the heart by 48 hpf, and also in the developing brain, jaw structures and pectoral fins. Morpholino-induced knockdown of zSTARS alters atrial and ventricular dimensions and decreases ventricular fractional shortening (measured by high-speed video microscopy), with pericardial edema and decreased or absent circulation [abnormal cardiac phenotypes in 126/164 (77%) of morpholino-injected embryos vs. 0/152 (0%) of control morpholino embryos]. Co-injection of zsrf (serum response factor) mRNA rescues the cardiac phenotype of zSTARS knockdown, resulting in improved fractional shortening and ventricular end-diastolic dimensions. Ectopic over-expression of STARS in vitro activates the STARS proximal promoter, which contains a conserved SRF site. Chromatin immunoprecipitation demonstrates that SRF binds to this site in vivo and the SRF inhibitor CCG-1423 completely blocks STARS proximal reporter activity in H9c2 cells.
Conclusions/Significance: This study demonstrates for the first time that STARS deficiency severely disrupts cardiac development and function in vivo and revealed a novel STARS-SRF feed-forward autoregulatory loop that could play an essential role in STARS regulation and cardiac function.

TI BAY61-3606 Affects the Viability of Colon Cancer Cells in a
Genotype-Directed Manner
SO PLOS ONE

DT Article

K-RAS; MEDIATES RESISTANCE; AZD6244 ARRY-142886; PATHWAY ACTIVATION; RNA
INTERFERENCE; IN-VIVO; INHIBITOR
AB Background: K-RAS mutation poses a particularly difficult problem for cancer therapy. Activating mutations in K-RAS are common in cancers of the lung, pancreas, and colon and are associated with poor response to therapy. As such, targeted therapies that abrogate K-RAS-induced oncogenicity would be of tremendous value.
Methods: We searched for small molecule kinase inhibitors that preferentially affect the growth of colorectal cancer cells expressing mutant K-RAS. The mechanism of action of one inhibitor was explored using chemical and genetic approaches.
Results: We identified BAY61-3606 as an inhibitor of proliferation in colorectal cancer cells expressing mutant forms of K-RAS, but not in isogenic cells expressing wild-type K-RAS. In addition to its anti-proliferative effects in mutant cells, BAY61-3606 exhibited a distinct biological property in wild-type cells in that it conferred sensitivity to inhibition of RAF. In this context, BAY61-3606 acted by inhibiting MAP4K2 (GCK), which normally activates NFkb signaling in wild-type cells in response to inhibition of RAF. As a result of MAP4K2 inhibition, wild-type cells became sensitive to AZ-628, a RAF inhibitor, when also treated with BAY61-3606.
Conclusions: These studies indicate that BAY61-3606 exerts distinct biological activities in different genetic contexts.

TI Mechanical Stretch and PI3K Signaling Link Cell Migration and

AB Organ development leads to the emergence of organ function, which in turn can impact developmental processes. Here we show that fluid flow-induced collective epithelial migration during kidney nephron morphogenesis induces cell stretch that in turn signals epithelial proliferation. Increased cell proliferation was dependent on PI3K signaling. Inhibiting epithelial proliferation by blocking PI3K or CDK4/Cyclin D1 activity arrested cell migration prematurely and caused a marked overstretching of the distal nephron tubule. Computational modeling of the involved cell processes predicted major morphological and kinetic outcomes observed experimentally under a variety of conditions. Overall, our findings suggest that kidney development is a recursive process where emerging organ function "feeds back" to the developmental program to influence fundamental cellular events such as cell migration and proliferation, thus defining final organ morphology.

AB Abnormal accumulation of alpha-synuclein is centrally involved in the pathogenesis of many disorders with Parkinsonism and dementia. Previous in vitro studies suggest that alpha-synuclein dysregulates intracellular calcium. However, it is unclear whether these alterations occur in vivo. For this reason, we investigated calcium dynamics in transgenic mice expressing human WT alpha-synuclein using two-photon microscopy. We imaged spontaneous and stimulus-induced neuronal activity in the barrel cortex. Transgenic mice exhibited augmented, long-lasting calcium transients characterized by considerable deviation from the exponential decay. The most evident pathology was observed in response to a repetitive stimulation in which subsequent stimuli were presented before relaxation of calcium signal to the baseline. These alterations were detected in the absence of significant increase in neuronal spiking response compared with age-matched controls, supporting the possibility that alpha-synuclein promoted alterations in calcium dynamics via interference with intracellular buffering mechanisms. The characteristic shape of calcium decay and augmented response during repetitive stimulation can serve as in vivo imaging biomarkers in this model of neurodegeneration, to monitor progression of the disease and screen candidate treatment strategies.

CORTEX; VISUAL-MOTION; BAYESIAN-INFERENCE; MACAQUE MONKEY; CORTICAL
AREA; NEURONS; MT; DISCRIMINATION
AB Successful decision making involves combining observations of the external world with prior knowledge. Recent studies suggest that neural activity in macaque lateral intraparietal area (LIP) provides a useful window into this process. This study examines how rapidly changing prior knowledge about an upcoming sensory stimulus influences the computations that convert sensory signals into plans for action. Two monkeys performed a cued direction discrimination task, in which an arrow cue presented at the start of each trial communicated the prior probability of the direction of stimulus motion. We hypothesized that the cue would either shift the initial level of LIP activity before sensory evidence arrived, or it would scale sensory responses according to the prior probability of each stimulus, manifesting as a change in slope of LIP firing rates. Neural recordings demonstrated a clear shift in the activity level of LIP neurons following the arrow cue, which persisted into the presentation of the motion stimulus. No significant change in slope of responses was observed, suggesting that sensory gain was not strongly modulated. To confirm the latter observation, middle temporal area (MT) neurons were recorded during a version of the cued direction discrimination task, and we found no change in MT responses resulting from the presentation of the directional cue. These results suggest that information about an immediately upcoming stimulus does not scale the sensory response, but rather changes the amount of evidence that must be accumulated to reach a decision in areas that are involved in planning action.

AB The development of mouse/human chimeras through the engraftment of human immune cells and tissues into immunodeficient mice, including the recently described humanized BLT (bone marrow, liver, thymus) mouse model, holds great promise to facilitate the in vivo study of human immune responses. However, little data exist regarding the extent to which cellular immune responses in humanized mice accurately reflect those seen in humans. We infected humanized BLT mice with HIV-1 as a model pathogen and characterized HIV-1-specific immune responses and viral evolution during the acute phase of infection. HIV-1-specific CD8(+) T cell responses in these mice were found to closely resemble those in humans in terms of their specificity, kinetics, and immunodominance. Viral sequence evolution also revealed rapid and highly reproducible escape from these responses, mirroring the adaptations to host immune pressures observed during natural HIV-1 infection. Moreover, mice expressing the protective HLA-B*57 allele exhibited enhanced control of viral replication and restricted the same CD8(+) T cell responses to conserved regions of HIV-1 Gag that are critical to its control of HIV-1 in humans. These data reveal that the humanized BLT mouse model appears to accurately recapitulate human pathogen-specific cellular immunity and the fundamental immunological mechanisms required to control a model human pathogen, aspects critical to the use of a small-animal model for human pathogens.

AB Context There is increasing interest in reporting risk-standardized outcomes for Medicare beneficiaries hospitalized with acute ischemic stroke, but whether it is necessary to include adjustment for initial stroke severity has not been well studied.
Objective To evaluate the degree to which hospital outcome ratings and potential eligibility for financial incentives are altered after including initial stroke severity in a claims-based risk model for hospital 30-day mortality for acute ischemic stroke.
Design, Setting, and Patients Data were analyzed from 782 Get With The Guidelines-Stroke participating hospitals on 127 950 fee-for-service Medicare beneficiaries with ischemic stroke who had a score documented for the National Institutes of Health Stroke Scale (NIHSS, a 15-item neurological examination scale with scores from 0 to 42, with higher scores indicating more severe stroke) between April 2003 and December 2009. Performance of claims-based hospital mortality risk models with and without inclusion of NIHSS scores for 30-day mortality was evaluated and hospital rankings from both models were compared.
Main Outcomes Measures Model discrimination, hospital 30-day mortality outcome rankings, and value-based purchasing financial incentive categories.
Results Across the study population, the mean (SD) NIHSS score was 8.23 (8.11) (median, 5; interquartile range, 2-12). There were 18 186 deaths (14.5%) within the first 30 days, including 7430 deaths (5.8%) during the index hospitalization. The hospital mortality model with NIHSS scores had significantly better discrimination than the model without (C statistic, 0.864; 95% CI, 0.861-0.867, vs 0.772; 95% CI, 0.769-0.776; P < .001). Among hospitals ranked in the top 20% or bottom 20% of performers by the claims model without NIHSS scores, 26.3% were ranked differently by the model with NIHSS scores. Of hospitals initially classified as having "worse than expected" mortality, 57.7% were reclassified to "as expected" by the model with NIHSS scores. The net reclassification improvement (93.1%; 95% CI, 91.6%-94.6%; P < .001) and integrated discrimination improvement (15.0%; 95% CI, 14.6%-15.3%; P < .001) indexes both demonstrated significant enhancement of model performance after the addition of NIHSS. Explained variance and model calibration was also improved with the addition of NIHSS scores.
Conclusion Adding stroke severity as measured by the NIHSS to a hospital 30-day risk model based on claims data for Medicare beneficiaries with acute ischemic stroke was associated with considerably improved model discrimination and change in mortality performance rankings for a substantial portion of hospitals.

AB Background: To determine the agreement between intraocular pressure and the 'Wuerzburg bleb classification score', as well as between single items of the score and intraocular pressure. Interobserver variability was analyzed.
Methods: 57 post-trabeculectomy eyes were included. Colour photographs were used to score the filtering bleb in accordance to the Wuerzburg bleb classification score by two different examiners. At the same visit, clinical data such as intraocular pressure, best corrected visual acuity, slit lamp biomicroscopy and medical history were obtained by another examiner.
Results: After trabeculectomy, 42 out of 57 eyes (73.7%) reached the target pressure (<= 21mmHg, and intraocular pressure reduction of at least 20%, without antiglaucoma medication, and without any additional intervention). Fair agreement was found between intraocular pressure and Wuerzburg bleb classification score >= 8 points and >= 7 points (kappa 0.24 and 0.27, respectively). Analyzing the subgroups of the morphological criteria, best agreement was found between occurrence of microcysts and target intraocular pressure (kappa 0.22 - 0.34).
Conclusions: Evaluating filtering blebs after trabeculectomy by using the Wuerzburg bleb classification score is a good technique for predicting intraocular pressure control in eyes attaining a minimum score of seven points. The presence of microcysts on the filtering bleb predicts that the eye is likely to attain target pressure.

AB Sequence analysis suggests that KALRN, a Rho GDP/GTP exchange factor genetically linked to schizophrenia, could contain as many as nine tandem spectrin repeats (SRs). We expressed and purified fragments of Kalirin containing from one to five putative SRs to determine whether they formed nested structures that could endow Kalirin with the flexible rodlike properties characteristic of spectrin and dystrophin. Far-UV circular dichroism studies indicated that Kalirin contains nine SRs. On the basis of thermal denaturation, sensitivity to chemical denaturants, and the solubility of pairs of repeats, the nine SRs of Kalirin form nested structures. Modeling studies confirmed this conclusion and identified an exposed loop in SRS; consistent with the modeling, this loop was extremely labile to proteolytic cleavage. Analysis of a direpeat fragment (SR4:5) encompassing the region of Kalirin known to interact with NOS2, DISC-1, PAM, and Arf6 identified this as the least stable region. Analytical ultracentrifugation indicated that SR1:3, SR4:6, and SR7:9 were monomers and adopted an extended conformation. Gel filtration suggested that Delta Kal7, a natural isoform that includes SR5:9, was monomeric and was not more extended than SR5:9. Similarly, the nine SRs of Kal7, which was also monomeric, were not more extended than SR5:9. The rigidity and flexibility of the nine SRs of Kal7, which separate its essential N-terminal Sec14p domain from its catalytic domain, play an essential role in its contribution to the formation and function of dendritic spines.

AB Heat shock proteins (HSPs) play a critical role in many intracellular processes, including apoptosis and delivery of other proteins to intracellular compartments. Small HSPs have been shown previously to participate in many cellular functions, including IL-8 induction. Human adenovirus infection activates intracellular signaling, involving particularly the c-Src and mitogen-activated protein kinases [Natarajan, K, et al. (2003) J. Immunol. 170, 6234-6243]. HSP27 and MK2 are also phosphorylated, and c-Src, and its downstream targets, p38, ERK1/2, and c-Jun-terminal kinase (JNK), differentially mediate IL-8 and MCP-1 expression. Specifically, activation and translocation of transcription factor NF kappa B-p65 occurs in a p38-dependent fashion [Rajaiya, J., et al. (2009) Mol. Vision 15, 2879-2889]. Herein, we report a novel role for HSP27 in an association of p38 with NF kappa B-p65. Immunoprecipitation assays of virus-infected but not mock-infected cells revealed a signaling complex including p38 and NF kappa B-p65. Transfection with HSP27 short interfering RNA (siRNA) but not scrambled RNA disrupted this association and reduced the level of IL-8 expression. Transfection with HSP27 siRNA also reduced the level of nuclear localization of NF kappa B-p65 and p38. By use of tagged p38 mutants, we found that amino acids 279-347 of p38 are necessary for the association of p38 with NF kappa B-p65. These studies strongly suggest that HSP27, p38, and NF kappa B-p65 form a signalosome in virus-infected cells and influence downstream expression of pro-inflammatory mediators.

AB In the liver of female mice, the transcriptional activity of estrogen receptor (ER) alpha oscillates in phase with the 4-d-long estrous cycle. Here systemic, genome-wide analysis demonstrates that ER tetradian oscillation is necessary to generate pulses of expression in genes for fatty acid and cholesterol synthesis. This ER-dependent metabolic programming changes with pregnancy and after cessation of ovarian function due to age or surgical menopause, suggesting that ER signaling is optimized to coordinate liver functions with the energetic requirements of each reproductive stage. Alterations of amplitude and frequency of the tetradian cycle, as observed after surgical menopause, age, or specific ablation of the hepatic Igf-1 gene, are associated with liver fat deposition. Appropriate hormone replacement therapy reinstating the oscillatory activity of liver ER prevents the effect of surgical menopause on fat deposition in liver.

AB Objectives This study sought to determine the association of fibroblast growth factor (FGF)-23 with death, heart failure (HF), and cardiovascular disease (CVD) in the general population, as well as the influence of chronic kidney disease (CKD) in this setting.
Background FGF-23 increases renal phosphorus excretion and inhibits vitamin D activation. In end-stage renal disease, high FGF-23 levels are associated with mortality. The association of FGF-23 with death, HF, and CVD in the general population, and the influence of CKD in this setting, are unknown.
Methods Plasma FGF-23 was measured in 3,107 community-living persons >= 65 years of age in 1996 and 1997, and participants were followed through 2008. HF and CVD events were adjudicated by a panel of experts. Associations of FGF-23 with each outcome were evaluated using Cox proportional hazards models, and we tested whether associations differed by CKD status.
Results Both lower estimated glomerular filtration rate and higher urine albumin to creatinine ratios were associated with high FGF-23 at baseline. During 10.5 years (median) follow-up, there were 1,730 deaths, 697 incident HF events, and 797 incident CVD events. Although high FGF-23 concentrations were associated with each outcome in combined analyses, the associations were consistently stronger for those with CKD (p interactions all <0.006). In the CKD group (n = 1,128), the highest FGF-23 quartile had adjusted hazards ratios (HR) of 1.87 (95% confidence interval [CI]: 1.47 to 2.38) for all-cause death, 1.94 (95% CI: 1.32 to 2.83) for incident HF, and 1.49 (95% CI: 1.02 to 2.18) for incident CVD events compared with the lowest quartile. Corresponding HRs in those without CKD (n = 1,979) were 1.29 (95% CI: 1.05 to 1.59), 1.37 (95% CI: 0.99 to 1.89), and 1.07 (95% CI: 0.79 to 1.45).
Conclusions FGF-23, a hormone involved in phosphorous and vitamin D homeostasis, is independently associated with all-cause death and incident HF in community-living older persons. These associations appear stronger in persons with CKD. (J Am Coll Cardiol 2012;60:200-7) (c) 2012 by the American College of Cardiology Foundation

AB We demonstrate a stochastic based method for performing active rheology using optical tweezers. By monitoring the displacement of an embedded particle in response to stochastic optical forces, a rapid estimate of the frequency dependent shear moduli of a sample is achieved in the range of 10(-1)-10(3) Hz. We utilize the method to probe linear viscoelastic properties of hydrogels at varied cross-linker concentrations. Combined with fluorescence imaging, our method demonstrates non-linear changes of bond strength between T cell receptors and an antigenic peptide due to force-induced cell activation.

AB Background: Myeloid derived suppressor cells (MDSC) are important regulators of immune responses. We evaluated the mechanistic role of MDSC depletion on antigen presenting cell (APC), NK, T cell activities and therapeutic vaccination responses in murine models of lung cancer.
Principal Findings: Individual antibody mediated depletion of MDSC (anti-Gr1 or anti-Ly6G) enhanced the antitumor activity against lung cancer. In comparison to controls, MDSC depletion enhanced the APC activity and increased the frequency and activity of the NK and T cell effectors in the tumor. Compared to controls, the anti-Gr1 or anti-Ly6G treatment led to increased: (i) CD8 T cells, (ii) NK cells, (iii) CD8 T or NK intracytoplasmic expression of IFN gamma, perforin and granzyme (iv) CD3 T cells expressing the activation marker CD107a and CXCR3, (v) reduced CD8 T cell IL-10 production in the tumors (vi) reduced tumor angiogenic (VEGF, CXCL2, CXCL5, and Angiopoietin1& 2) but enhanced anti-angiogenic (CXCL9 and CXCL10) expression and (vii) reduced tumor staining of endothelial marker Meca 32. Immunocytochemistry of tumor sections showed reduced Gr1 expressing cells with increased CD3 T cell infiltrates in the anti-Gr1 or anti-Ly6G groups. MDSC depletion led to a marked inhibition in tumor growth, enhanced tumor cell apoptosis and reduced migration of the tumors from the primary site to the lung compared to controls. Therapeutic vaccination responses were enhanced in vivo following MDSC depletion with 50% of treated mice completely eradicating established tumors. Treated mice that rejected their primary tumors acquired immunological memory against a secondary tumor challenge. The remaining 50% of mice in this group had 20 fold reductions in tumor burden compared to controls.
Significance: Our data demonstrate that targeting MDSC can improve antitumor immune responses suggesting a broad applicability of combined immune based approaches against cancer. This multifaceted approach may prove useful against tumors where MDSC play a role in tumor immune evasion.

AB Angiogenesis plays a critical role in processes such as organ development, wound healing, and tumor growth. It requires well-orchestrated integration of soluble and matrix factors and timely recognition of such signals to regulate this process. Previous work has shown that newly forming vessels express the chemokine receptor CXC receptor 3 (CXCR3) and, activation by its ligand IP-10 (CXCL10), both inhibits development of new vasculature and causes regression of newly formed vessels. To identify and develop new therapeutic agents to limit or reverse pathological angiogenesis, we identified a 21 amino acid fragment of IP-10, spanning the a-helical domain residues 77-98, that mimic the actions of the whole IP-10 molecule on endothelial cells. Treatment of the endothelial cells with the 22 amino acid fragment referred to as IP-10p significantly inhibited VEGF-induced endothelial motility and tube formation in vitro, properties critical for angiogenesis. Using a Matrigel plug assay in vivo, we demonstrate that IP-10p both prevented vessel formation and induced involution of nascent vessels. CXCR3 neutralizing antibody was able to block the inhibitory effects of the IP-10p, demonstrating specificity of the peptide. Inhibition of endothelial function by IP-10p was similar to that described for IP-10, secondary to CXCR3-mediated increase in cAMP production, activation of PKA inhibiting cell migration, and inhibition of VEGF-mediated m-calpain activation. IP-10p provides a novel therapeutic agent that inhibits endothelial cell function thus, allowing for the modulation of angiogenesis.

AB Recently, deriving candidate endophenotypes from brain imaging data has become a valuable approach to study genetic influences on schizophrenia (SZ), whose pathophysiology remains unclear. In this work we utilized a multivariate approach, parallel independent component analysis, to identify genomic risk components associated with brain function abnormalities in SZ. 5157 candidate single nucleotide polymorphisms (SNPs) were derived from genome-wide array based on their possible connections with SZ and further investigated for their associations with brain activations captured with functional magnetic resonance imaging (fMRI) during a sensorimotor task. Using data from 92 SZ patients and 116 healthy controls, we detected a significant correlation (r = 0.29; p = 2.41 x 10(-5)) between one fMRI component and one SNP component, both of which significantly differentiated patients from controls. The fMRI component mainly consisted of precentral and postcentral gyri, the major activated regions in the motor task. On average, higher activation in these regions was observed in participants with higher loadings of the linked SNP component, predominantly contributed to by 253 SNPs. 138 identified SNPs were from known coding regions of 100 unique genes. 31 identified SNPs did not differ between groups, but moderately correlated with some other group-discriminating SNPs, indicating interactions among alleles contributing toward elevated SZ susceptibility. The genes associated with the identified SNPs participated in four neurotransmitter pathways: GABA receptor signaling, dopamine receptor signaling, neuregulin signaling and glutamate receptor signaling. In summary, our work provides further evidence for the complexity of genomic risk to the functional brain abnormality in SZ and suggests a pathological role of interactions between SNPs, genes and multiple neurotransmitter pathways.

AB Response inhibition, or the suppression of prepotent but contextually inappropriate behaviors, is essential to adaptive, flexible responding. Individuals with autism spectrum disorders (ASD) consistently show deficient response inhibition during antisaccades. In our prior functional MRI study, impaired antisaccade performance was accompanied by reduced functional connectivity between the frontal eye field (FEF) and dorsal anterior cingulate cortex (dACC), regions critical to volitional ocular motor control. Here we employed magnetoencephalography (MEG) to examine the spectral characteristics of this reduced connectivity. We focused on coherence between FEF and dACC during the preparatory period of antisaccade and prosaccade trials, which occurs after the presentation of the task cue and before the imperative stimulus. We found significant group differences in alpha band mediated coherence. Specifically, neurotypical participants showed significant alpha band coherence between the right inferior FEF and right dACC and between the left superior FEF and bilateral dACC across antisaccade, prosaccade, and fixation conditions. Relative to the neurotypical group, ASD participants showed reduced coherence between these regions in all three conditions. Moreover, while neurotypical participants showed increased coherence between the right inferior FEF and the right dACC in preparation for an antisaccade compared to a prosaccade or fixation, ASD participants failed to show a similar increase in preparation for the more demanding antisaccade. These findings demonstrate reduced long-range functional connectivity in ASD, specifically in the alpha band. The failure in the ASD group to increase alpha band coherence with increasing task demand may reflect deficient top-down recruitment of additional neural resources in preparation to perform a difficult task.

AB Multimodal imaging improves the accuracy of the localization and the quantification of brain activation when measuring different manifestations of the hemodynamic response associated with cerebral activity. In this study, we incorporated cerebral blood flow (CBF) changes measured with arterial spin labeling (ASL), Diffuse Optical Tomography (DOT) and blood oxygen level-dependent (BOLD) recordings to reconstruct changes in oxy- (Delta HbO(2)) and deoxyhemoglobin (Delta HbR). Using the Grubb relation between relative changes in CBF and cerebral blood volume (CBV), we incorporated the ASL measurement as a prior to the total hemoglobin concentration change (Delta HbT). We applied this ASL fusion model to both synthetic data and experimental multimodal recordings during a 2-s finger-tapping task. Our results show that the new approach is very powerful in estimating Delta HbO(2) and Delta HbR with high spatial and quantitative accuracy. Moreover, our approach allows the computation of baseline total hemoglobin concentration (HbT(0)) as well as of the BOLD calibration factor M on a single subject basis. We obtained an average HbT(0) of 71 mu M, an average M value of 0.18 and an average increase of 13% in cerebral metabolic rate of oxygen (CMRO2), all of which are in agreement with values previously reported in the literature. Our method yields an independent measurement of M, which provides an alternative measurement to validate the hypercapnic calibration of the BOLD signal. (C) 2012 Elsevier Inc. All rights reserved.

AB Functional MRI (fMRI) allows one to study task-related regional responses and task-dependent connectivity analysis using psychophysiological interaction (PPI) methods. The latter affords the additional opportunity to understand how brain regions interact in a task-dependent manner. The current implementation of PPI in Statistical Parametric Mapping (SPM8) is configured primarily to assess connectivity differences between two task conditions, when in practice fMRI tasks frequently employ more than two conditions. Here we evaluate how a generalized form of context-dependent PPI (gPPI; http://www.nitrc.org/projects/gppi), which is configured to automatically accommodate more than two task conditions in the same PPI model by spanning the entire experimental space, compares to the standard implementation in SPM8. These comparisons are made using both simulations and an empirical dataset. In the simulated dataset, we compare the interaction beta estimates to their expected values and model fit using the Akaike information criterion (AIC). We found that interaction beta estimates in gPPI were robust to different simulated data models, were not different from the expected beta value, and had better model fits than when using standard PPI (sPPI) methods. In the empirical dataset, we compare the model fit of the gPPI approach to sPPI. We found that the gPPI approach improved model fit compared to sPPI. There were several regions that became nonsignificant with gPPI. These regions all showed significantly better model fits with gPPI. Also, there were several regions where task-dependent connectivity was only detected using gPPI methods, also with improved model fit. Regions that were detected with all methods had more similar model fits. These results suggest that gPPI may have greater sensitivity and specificity than standard implementation in SPM. This notion is tempered slightly as there is no gold standard; however, data simulations with a known outcome support our conclusions about gPPI. In sum, the generalized form of context-dependent PPI approach has increased flexibility of statistical modeling, and potentially improves model fit, specificity to true negative findings, and sensitivity to true positive findings.

AB Longitudinal image analysis has become increasingly important in clinical studies of normal aging and neurodegenerative disorders. Furthermore, there is a growing appreciation of the potential utility of longitudinally acquired structural images and reliable image processing to evaluate disease modifying therapies. Challenges have been related to the variability that is inherent in the available cross-sectional processing tools, to the introduction of bias in longitudinal processing and to potential over-regularization. In this paper we introduce a novel longitudinal image processing framework, based on unbiased, robust, within-subject template creation, for automatic surface reconstruction and segmentation of brain MRI of arbitrarily many time points. We demonstrate that it is essential to treat all input images exactly the same as removing only interpolation asymmetries is not sufficient to remove processing bias. We successfully reduce variability and avoid over-regularization by initializing the processing in each time point with common information from the subject template. The presented results show a significant increase in precision and discrimination power while preserving the ability to detect large anatomical deviations; as such they hold great potential in clinical applications, e.g. allowing for smaller sample sizes or shorter trials to establish disease specific biomarkers or to quantify drug effects.

AB Structural analysis of MRI data on the cortical surface usually focuses on cortical thickness. Cortical surface area, when considered, has been measured only over gross regions or approached indirectly via comparisons with a standard brain. Here we demonstrate that direct measurement and comparison of the surface area of the cerebral cortex at a fine scale is possible using mass conservative interpolation methods. We present a framework for analyses of the cortical surface area, as well as for any other measurement distributed across the cortex that is areal by nature. The method consists of the construction of a mesh representation of the cortex, registration to a common coordinate system and, crucially, interpolation using a pycnophylactic method. Statistical analysis of surface area is done with power-transformed data to address lognormality, and inference is done with permutation methods. We introduce the concept of facewise analysis, discuss its interpretation and potential applications. (C) 2012 Elsevier Inc. All rights reserved.

AB We identified a new calmodulin kinase I (CaMKI) substrate, cytidyltransferase (CCT alpha), a crucial enzyme required for maintenance of cell membranes. CCT alpha becomes activated with translocation from the cytoplasm to the nuclear membrane, resulting in increased membrane phospholipids. Calcium-activated CCT alpha nuclear import is mediated by binding of its C-terminus to 14-3-3 zeta, a regulator of nuclear trafficking. Here CaMK1 phosphorylates residues within this C-terminus that signals association of CCT alpha with 14-3-3 zeta to initiate calcium-induced nuclear entry. CaMKI docks within the CCT alpha membrane-binding domain (residues 290-299), a sequence that displays similarities to a canonical nuclear export signal (NES) that also binds CRM1/exportin 1. Expression of a CFP-CCT alpha mutant lacking residues 290-299 in cells results in cytosolically retained enzyme. CRM1/exportin 1 was required for CCT alpha nuclear export, and its overexpression in cells was partially sufficient to trigger CCT alpha nuclear export despite calcium stimulation. An isolated CFP-290-299 peptide remained in the nucleus in the presence of leptomycin B but was able to target to the cytoplasm with farnesol. Thus CaMKI vies with CRM1/exportin 1 for access to a NES, and assembly of a CaMKI-14-3-3.-CCT alpha complex is a key effector mechanism that drives nuclear CCTa translocation.

AB Detection of cell-free tumor DNA in the blood has offered promise as a cancer biomarker, but practical clinical implementations have been impeded by the lack of a sensitive and accurate method for quantitation that is also simple, inexpensive, and readily scalable. Here we present an approach that uses next-generation sequencing to quantify the small fraction of DNA molecules that contain tumor-specific mutations within a background of normal DNA in plasma. Using layers of sequence redundancy designed to distinguish true mutations from sequencer misreads and PCR misincorporations, we achieved a detection sensitivity of approximately 1 variant in 5,000 molecules. In addition, the attachment of modular barcode tags to the DNA fragments to be sequenced facilitated the simultaneous analysis of more than 100 patient samples. As proof-of-principle, we showed the successful use of this method to follow treatment-associated changes in circulating tumor DNA levels in patients with non-small cell lung cancer. Our findings suggest that the deep sequencing approach described here may be applied to the development of a practical diagnostic test that measures tumor-derived DNA levels in blood.

AB Crizotinib (PF02341066, Xalkori; Pfizer) was recently approved by the U. S. Food and Drug Administration for treatment of ALK-positive non-small cell lung cancer (NSCLC) as defined by a jointly approved diagnostic test using a break-apart fluorescence in situ hybridization assay. The approval was based on dramatic response rates in ALK-positive NSCLC patients of 54% to 61% in phase I and II trials. To date, the overall disease control rates in these trials are close to 90%. Progression-free survival approaches 10 months. This review focuses on the ALK-inhibitory activity of crizotinib in preclinical and clinical trials that led to approval, as well as the diagnostic methods to classify patients with ALK-positive NSCLC. Although these patients represent a small subset of all patients with NSCLC, the rapid time course from identification of this unique target to an approved targeted therapy with striking benefit serves as a paradigm for the development of targeted therapeutics in an era of personalized medicine.

AB Purpose: The disease course of chronic lymphocytic leukemia (CLL) varies significantly within cytogenetic groups. We hypothesized that high-resolution genomic analysis of CLL would identify additional recurrent abnormalities associated with short time-to-first therapy (TTFT).
Experimental Design: We undertook high-resolution genomic analysis of 161 prospectively enrolled CLLs using Affymetrix 6.0 SNP arrays, and integrated analysis of this data set with gene expression profiles.
Results: Copy number analysis (CNA) of nonprogressive CLL reveals a stable genotype, with a median of only 1 somatic CNA per sample. Progressive CLL with 13q deletion was associated with additional somatic CNAs, and a greater number of CNAs was predictive of TTFT. We identified other recurrent CNAs associated with short TTFT: 8q24 amplification focused on the cancer susceptibility locus near MYC in 3.7%; 3q26 amplifications focused on PIK3CA in 5.6%; and 8p deletions in 5% of patients. Sequencing of MYC further identified somatic mutations in two CLLs. We determined which catalytic subunits of phosphoinositide 3-kinase (PI3K) were in active complex with the p85 regulatory subunit and showed enrichment for the a subunit in three CLLs carrying PIK3CA amplification.
Conclusions: Our findings implicate amplifications of 3q26 focused on PIK3CA and 8q24 focused on MYC in CLL. Clin Cancer Res; 18(14); 3791-802. (C)2012 AACR.

AB Purpose: Extensive correlative studies in human prostate cancer as well as studies in vitro and in mouse models indicate that fibroblast growth factor receptor (FGFR) signaling plays an important role in prostate cancer progression. In this study, we used a probe compound for an FGFR inhibitor, which potently inhibits FGFR-1-3 and significantly inhibits FGFR-4. The purpose of this study is to determine whether targeting FGFR signaling from all four FGFRs will have in vitro activities consistent with inhibition of tumor progression and will inhibit tumor progression in vivo.
Experimental Design: Effects of AZ8010 on FGFR signaling and invasion were analyzed using immortalized normal prostate epithelial (PNT1a) cells and PNT1a overexpressing FGFR-1 or FGFR-4. The effect of AZ8010 on invasion and proliferation in vitro was also evaluated in prostate cancer cell lines. Finally, the impact of AZ8010 on tumor progression in vivo was evaluated using a VCaP xenograft model.
Results: AZ8010 completely inhibits FGFR-1 and significantly inhibits FGFR-4 signaling at 100 nmol/L, which is an achievable in vivo concentration. This results in marked inhibition of extracellular signal-regulated kinase (ERK) phosphorylation and invasion in PNT1a cells expressing FGFR-1 and FGFR-4 and all prostate cancer cell lines tested. Treatment in vivo completely inhibited VCaP tumor growth and significantly inhibited angiogenesis and proliferation and increased cell death in treated tumors. This was associated with marked inhibition of ERK phosphorylation in treated tumors.

AB Purpose: Accurate tumor classification is essential for cancer management as patient outcomes improve with use of site-and subtype-specific therapies. Current clinicopathologic evaluation is varied in approach, yet standardized diagnoses are critical for determining therapy. While gene expression-based cancer classifiers may potentially meet this need, imperative to determining their application to patient care is validation in rigorously designed studies. Here, we examined the performance of a 92-gene molecular classifier in a large multi-institution cohort.
Experimental Design: Case selection incorporated specimens from more than 50 subtypes, including a range of tumor grades, metastatic and primary tumors, and limited tissue samples. Formalin-fixed, paraffin-embedded tumors passed pathologist-adjudicated review between three institutions. Tumor classification using a 92-gene quantitative reverse transcriptase polymerase chain reaction (RT-PCR) assay was conducted on blinded tumor sections from 790 cases and compared with adjudicated diagnoses.
Results: The 92-gene assay showed overall sensitivities of 87% for tumor type [95% confidence interval (CI), 84-89] and 82% for subtype (95% CI, 79-85). Analyses of metastatic tumors, high-grade tumors, or cases with limited tissue showed no decrease in comparative performance (P = 0.16, 0.58, and 0.16). High specificity (96%-100%) was showed for ruling in a primary tumor in organs commonly harboring metastases. The assay incorrectly excluded the adjudicated diagnosis in 5% of cases.
Conclusions: The 92-gene assay showed strong performance for accurate molecular classification of a diverse set of tumor histologies. Results support potential use of the assay as a standardized molecular adjunct to routine clinicopathologic evaluation for tumor classification and primary site diagnosis.

ASSESSMENT; CULPRIT LESIONS; STABLE ANGINA; CT; GUIDELINES
AB We tested the hypothesis that morphologic lesion assessment helps detect acute coronary syndrome (ACS) during index hospitalization in patients with acute chest pain and significant stenosis on coronary computed tomographic angiogram (CTA). Patients who presented to an emergency department with chest pain but no objective signs of myocardial ischemia (nondiagnostic electrocardiogram and negative initial biomarkers) underwent CT angiography. CTA was analyzed for degree and length of stenosis, plaque area and volume, remodeling index, CT attenuation of plaque, and spotty calcium in all patients with significant stenosis (>50% in diameter) on CTA. ACS during index hospitalization was determined by a panel of 2 physicians blinded to results of CT angiography. For lesion characteristics associated with ACS, we determined cutpoints optimized for diagnostic accuracy and created lesion scores. For each score, we determined the odds ratio (OR) and discriminatory capacity for the prediction of ACS. Of the overall population of 368 patients, 34 had significant stenosis and 21 of those had ACS. Scores A (remodeling index plus spotty calcium: OR 3.5, 95% confidence interval [CI] 1.2 to 10.1, area under curve [AUC] 0.734), B (remodeling index plus spotty calcium plus stenosis length: OR 4.6, 95% CI 1.6 to 13.7, AUC 0.824), and C (remodeling index plus spotty calcium plus stenosis length plus plaque volume <90 HU: OR 3.4, 95% CI 1.5 to 7.9, AUC 0.833) were significantly associated with ACS. In conclusion, in patients presenting with acute chest pain and stenosis on coronary CTA, a CT-based score incorporating morphologic characteristics of coronary lesions had a good discriminatory value for detection of ACS during index hospitalization.

AB The National Cholesterol Education Program Adult Treatment Panel (ATP) has provided education and guidance for decades on the management of hypercholesterolemia. Its third report (ATP III) was published 10 years ago, with a white paper update in 2004. There is a need for translation of more recent evidence into a revised guideline. To help address the significant challenges facing the ATP IV writing group, this statement aims to provide balanced recommendations that build on ATP III. The authors aim for simplicity to increase the likelihood of implementation in clinical practice. To move from ATP III to ATP IV, the authors recommend the following: (1) assess risk more accurately, (2) simplify the starting algorithm, (3) prioritize statin therapy, (4) relax the follow-up interval for repeat lipid testing, (5) designate <70 mg/di as an "ideal" low-density lipoprotein cholesterol target, (6) endorse targets beyond low-density lipoprotein cholesterol, (7) refine therapeutic target levels to the equivalent population percentile, (8) remove misleading descriptors such as "borderline high," and (9) make lifestyle messages simpler. In conclusion, the solutions offered in this statement represent ways to translate the totality of published reports into enhanced hyperlipidemia guidelines to better combat the devastating impact of hyperlipidemia on cardiovascular health.

AB This study investigated the role of inducible nitric oxide synthase (iNOS) in failure of ethanol-induced fatty liver grafts. Rat livers were explanted 20 h after gavaging with ethanol (5 g/kg) and storing in UW solution for 24 h before implantation. Hepatic oil red O staining-positive areas increased from similar to 2 to similar to 33% after ethanol treatment, indicating steatosis. iNOS expression increased similar to 8-fold after transplantation of lean grafts (LG) and 25-fold in fatty grafts (FG). Alanine aminotransferase release, total bilirubin, hepatic necrosis, TUNEL-positive cells, and cleaved caspase-3 were higher in FG than LG. A specific iNOS inhibitor 1400W (5 mu M in the cold-storage solution) blunted these alterations by > 42% and increased survival of fatty grafts from 25 to 88%. Serum nitrite/nitrate and hepatic nitrotyrosine adducts increased to a greater extent after transplantation of FG than LG, indicating reactive nitrogen species (RNS) overproduction. Phospho-c-Jun and phospho-c-Jun N-terminal kinase-1/2 (JNK1/2) were higher in FG than in LG, indicating more JNK activation in fatty grafts. RNS formation and JNK activation were blunted by 1400W. Mitochondrial polarization and cell death were visualized by intravital multiphoton microscopy of rhodamine 123 and propidium iodide, respectively. After implantation, viable cells with depolarized mitochondria were 3-fold higher in FG than in LG and 1400W decreased mitochondrial depolarization in FG to the levels of LG. Taken together, iNOS is upregulated after transplantation of FG, leading to excessive RNS formation, JNK activation, mitochondrial dysfunction, and severe graft injury. The iNOS inhibitor 1400W could be an effective therapy for primary nonfunction of fatty liver grafts. (C) 2012 Elsevier Inc. All rights reserved.

AB Rationale: Idiopathic pulmonary fibrosis (IPF) is a chronic pulmonary disorder of unknown etiology with few treatment options. Although tetraspanins are involved in various diseases, their roles in fibrosis have not been determined.
Objectives: To investigate the role of tetraspanin CD151 in pulmonary fibrosis.
Methods: CD151 knockout (KO) mice were studied by histological, biochemical, and physiological analyses and compared with wildtype mice and CD9 KO mice. Further mechanistic analyses were performed in vitro, in vivo, and on samples from patients with IPF.
Measurements and Main Results: A microarray study identified an enrichment of genes involved in connective tissue disorders in the lungs of CD151 KO mice, but not in CD9 KO mice. Consistent with this, CD151 KO mice spontaneously exhibited age-related pulmonary fibrosis. Deletion of CD151 did not affect pulmonary fibroblast functions but instead degraded epithelial integrity via attenuated adhesion strength on the basement membrane; CD151-deleted alveolar epithelial cells exhibited increased alpha-SMA expression with activation of p-Smad2, leading to fibrotic changes in the lungs. This loss of epithelial integrity in CD151 KO lungs was further exacerbated by intratracheal bleomycin exposure, resulting in severe fibrosis with increased mortality. We also observed decreased numbers of CD151-positive alveolar epithelial cells in patients with IPF.
Conclusions: CD151 is essential for normal function of alveolar epithelial cells; loss of CD151 causes pulmonary fibrosis as a result of epithelial disintegrity. Given that CD151 may protect against fibrosis, this protein represents a novel target for the treatment of fibrotic diseases.

AB Claspin is a key mediator of the ATR-Chk1 checkpoint pathway. In response to DNA damage, Claspin interacts with Rad17 and Chk1 in a phosphorylation-dependent manner, enabling ATR to phosphorylate Chk1 efficiently. Claspin also interacts with Rad9, but how they interact and whether the interaction is functional remains unknown. Unexpectedly, our analysis of two splicing isoforms of Claspin provided an answer to these questions. The Claspin(1339) isoform contains an evolutionarily conserved C terminus, but the Claspin(1332) isoform does not. Although the transcripts encoding both Claspin isoforms coexist in HCT116 cells, Claspin(1339) is the predominant form responsible for Chk1 activation. When expressed in cells depleted of endogenous Claspin, both Claspin(1339) and Claspin(1332) are able to mediate Chk1 activation. However, the activation of Chk1 is delayed in Claspin(1332)-expressing cells compared with Claspin(1339)-expressing cells. Furthermore, only Claspin(1339) but not Claspin(1332) interacts with Rad9 efficiently. Together, these results suggest that the conserved C terminus of Claspin interacts with Rad9 and ensures timely activation of the ATR-Chk1 pathway.

AB Mutations in the SPRED1 (Sprouty-related protein with an EVH [Ena/Vasp homology] domain 1) and NF1 (neurofibromatosis 1) genes underlie clinically related human disorders. The NF1-encoded protein neurofibromin is a Ras GTPase-activating protein (GAP) and can directly limit Ras activity. Spred proteins also negatively regulate Ras signaling, but the mechanism by which they do so is not clear. In the July 1, 2012, issue of Genes & Development, Stowe and colleagues (pp. 1421-1426) present evidence that Spred1 recruits neurofibromin to the membrane, where it dampens growth factor-induced Ras activity, providing a satisfying explanation for the overlapping features of two human diseases.

AB Class Ia phosphatidylinositol 3 kinase (PI3K) is required for oncogenic receptor-mediated transformation; however, the individual roles of the two commonly expressed class Ia PI3K isoforms in oncogenic receptor signaling have not been elucidated in vivo. Here, we show that genetic ablation of p110 alpha blocks tumor formation in both polyoma middle T antigen (MT) and HER2/Neu transgenic models of breast cancer. Surprisingly, p110 beta ablation results in both increased ductal branching and tumorigenesis. Biochemical analyses suggest a competition model in which the less active p110 beta competes with the more active p110 alpha for receptor binding sites, thereby modulating the level of PI3K activity associated with activated receptors. Our findings demonstrate a novel p110 beta-based regulatory role in receptor-mediated PI3K activity and identify p110 alpha as an important target for treatment of HER2-positive disease.

AB Hematopoietic development occurs in complex microenvironments and is influenced by key signaling events. Yet how these pathways communicate with master hematopoietic transcription factors to coordinate differentiation remains incompletely understood. The transcription factor RUNX1 plays essential roles in definitive hematopoietic stem cell (HSC) ontogeny, HSC maintenance, megakaryocyte (Mk) maturation, and lymphocyte differentiation. It is also the most frequent target of genetic alterations in human leukemia. Here, we report that RUNX1 is phosphorylated by Src family kinases (SFKs) and that this occurs on multiple tyrosine residues located within its negative regulatory DNA-binding and autoinhibitory domains. Retroviral transduction, chemical inhibitor, and genetic studies demonstrate a negative regulatory role of tyrosine phosphorylation on RUNX1 activity in Mk and CD8 T-cell differentiation. We also demonstrate that the nonreceptor tyrosine phosphatase Shp2 binds directly to RUNX1 and contributes to its dephosphorylation. Last, we show that RUNX1 tyrosine phosphorylation correlates with reduced GATA1 and enhanced SWI/SNF interactions. These findings link SFK and Shp2 signaling pathways to the regulation of RUNX1 activity in hematopoiesis via control of RUNX1 multiprotein complex assembly.

AB MHC class I and class II are crucial for the adaptive immune system. Although regulation of MHC class II expression by CIITA has long been recognized, the mechanism of MHC class I transactivation has been largely unknown until the recent discovery of NLRC5/class I transactivator. In this study, we show using Nlrc5-deficient mice that NLRC5 is required for both constitutive and inducible MHC class I expression. Loss of Nlrc5 resulted in severe reduction in the expression of MHC class I and related genes such as beta(2)-microglobulin, Tap1, or Lmp2, but did not affect MHC class II levels. IFN-gamma stimulation could not overcome the impaired MHC class I expression in Nlrc5-deficient cells. Upon infection with Listeria monocyogenes, Nlrc5-deficient mice displayed impaired CD8(+) T cell activation, accompanied with increased bacterial loads. These findings illustrate critical roles of NLRC5/class I transactivator in MHC class I gene regulation and host defense by CD8(+) T cell responses. The Journal of Immunology, 2012, 189: 516-520.

AB Two quinolines identified as positive allosteric modulators of gamma-aminobutyric acid (GABA)(A) receptors containing the alpha(2) subunit, 9-amino-2-cyclobutyl-5-(6-methoxy-2-methylpyridin-3-yl)-2,3-dihydro-1H-pyrrolo[3,4-b]quinolin-1-one (4) and 9-amino-2-cyclobutyl-5-(2-methoxypyridin-3-yl)-2,3-dihydro-1H-pyrrolo[3,4-b]quinolin-1-one (5), were radiolabelled at the methoxy position with carbon-11 (half-life = 20.4 min). These quinolines represent a new class of potential radiotracers for imaging the benzodiazepine site of GABA(A) receptors with positron emission tomography (PET). Both radiotracers were reliably isolated following reaction of their respective pyridinone/pyridinol tautomeric precursors with [C-11]CH3I in clinically useful, formulated quantities (2.9% and 2.7% uncorrected radiochemical yield, respectively, relative to [C-11]CO2) with high specific activities (>70 GBq mu mol (1); >2 Ci mu mol(-1)) and high radiochemical purities (>95%). The radiosyntheses reported herein represent rare examples of selectively isolating radiolabelled compounds bearing [C-11]2-methoxypyridine moieties. Although both radiotracers demonstrated promising imaging characteristics based on preliminary ex vivo biodistribution studies in conscious rodents, higher brain uptake was observed with [C-11]5 and therefore this radiotracer was further evaluated. Carbon-11 labelled 5 readily penetrated the brain (>1 standard uptake value in cortical regions at 15 min post-injection of the radiotracer), had an appropriate regional brain distribution for GABA(A) receptors that appeared to be reversible, and did not show any appreciable radiometabolites in rat brain homogenates up to 15 min post-injection. Preadministration of flumazenil (1, 10mg kg (1)) or 5 (5 mg kg (1)) effectively blocked >50% of [C-11]5 binding to the GABA(A) receptor-rich regions, thereby suggesting that this radiotracer is worthy of further evaluation for imaging GABA(A) receptors. Additionally (R,S)-N-(1-(3-chloro-4-methoxyphenyl)ethyl)-3,3-diphenylpropan-1-amine, 6, an allosteric modulator of GABA(B) receptors, was efficiently labelled in one step using [C-11]methyl iodide. Ex vivo biodistribution studies in conscious rats showed low brain uptake, therefore, efforts are underway to discover alternative radiotracers to image GABA(B). In conclusion, [C-11]5 is worthy of further evaluation in higher species for imaging GABA(A) receptors in the central nervous system. Published by Elsevier Ltd.

AB BACKGROUND: This study examined the association between functional single-nucleotide polymorphisms in candidate genes from oxidative stress pathways and risk of radiation pneumonitis (RP) in patients treated with thoracic radiation therapy for locally advanced lung cancer. METHODS: A review was conducted of 136 patients treated with radiation therapy for lung cancer between 2001 and 2007, and who had prior genotyping of functional single-nucleotide polymorphisms in oxidative stress genes including superoxide dismutase 2 (SOD2; rs4880) and methylene tetrahydrofolate reductase (MTHFR; rs1801131, rs1801133). RP events were retrospectively scored using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0. Cox proportional hazard regression was performed to identify clinical variables and genotypes associated with risk of RP of grades =2 and =3 on univariate and multivariate analysis, respectively. P values were corrected for multiple hypothesis esting. RESULTS: With a median follow-up of 21.4 months, the incidence of grade =2 RP was 29% and grade =3 RP was 14%. On multivariate analysis, after adjusting for clinical factors such as concurrent chemotherapy and consolidation docetaxel, and lung dosimetric parameters such as volume receiving greater than 20 Gy and mean lung dose, MTHFR genotype (rs1801131; AA versus AC/CC) was significantly associated with risk of grade =2 RP (hazard ratio: 0.37; 95% confidence interval: 0.18-0.76; P = .006, corrected P = .018) and grade =3 RP (hazard ratio: 0.21; 95% confidence interval: 0.06-0.70; P = .01; corrected P = .03). SOD2 genotype was not associated with RP. CONCLUSIONS: This study showed an association between MTHFR genotype and risk of clinically significant RP. Further study of MTHFR-related pathways may provide insight into the mechanisms behind RP. Cancer 2012;36543665. (C) 2011 American Cancer Society.

AB Albuminuria and reduced glomerular filtration rate are manifestations of chronic kidney disease (CKD) that predict end-stage renal disease, acute kidney injury, cardiovascular disease and death. We hypothesized that SNPs identified in association with the estimated glomerular filtration rate (eGFR) would also be associated with albuminuria. Within the CKDGen Consortium cohort (n 31 580, European ancestry), we tested 16 eGFR-associated SNPs for association with the urinary albumin-to-creatinine ratio (UACR) and albuminuria [UACR 25 mg/g (women); 17 mg/g (men)]. In parallel, within the CARe Renal Consortium (n 5569, African ancestry), we tested seven eGFR-associated SNPs for association with the UACR. We used a Bonferroni-corrected P-value of 0.003 (0.05/16) in CKDGen and 0.007 (0.05/7) in CARe. We also assessed whether the 16 eGFR SNPs were associated with the UACR in aggregate using a beta-weighted genotype score. In the CKDGen Consortium, the minor A allele of rs17319721 in the SHROOM3 gene, known to be associated with a lower eGFR, was associated with lower ln(UACR) levels (beta 0.034, P-value 0.0002). No additional eGFR-associated SNPs met the Bonferroni-corrected P-value threshold of 0.003 for either UACR or albuminuria. In the CARe Renal Consortium, there were no associations between SNPs and UACR with a P 0.007. Although we found the genotype score to be associated with albuminuria (P 0.0006), this result was driven almost entirely by the known SHROOM3 variant, rs17319721. Removal of rs17319721 resulted in a P-value 0.03, indicating a weak residual aggregate signal. No alleles, previously demonstrated to be associated with a lower eGFR, were associated with the UACR or albuminuria, suggesting that there may be distinct genetic components for these traits.

AB Background. We used a Monte Carlo computer simulation to estimate the effectiveness and cost-effectiveness of screening for acute hepatitis C virus (HCV) infection in human immunodeficiency virus (HIV)-infected men who have sex with men.
Methods. One-time screening for prevalent HCV infection was performed at the time of enrollment in care, followed by either symptom-based screening, screening with liver function tests (LFTs), HCV antibody (Ab) screening, or HCV RNA screening in various combinations and intervals. We considered both treatment with pegylated interferon and ribavirin (PEG/RBV) alone and with an HCV protease inhibitor. Outcome measures were life expectancy, quality-adjusted life expectancy, direct medical costs, and cost-effectiveness, assuming a societal willingness to pay $100 000 per quality-adjusted life-year (QALY) gained.
Results. All strategies increased life expectancy (from 0.49 to 0.94 life-months), quality-adjusted life expectancy (from 0.47 to 1.00 quality-adjusted life-months), and costs (from $1900 to $7600), compared with symptom-based screening. The incremental cost-effectiveness ratio of screening with 6-month LFTs and a 12-month HCV Ab test, compared with symptom-based screening, was $43 700/QALY (for PEG/RBV alone) and $57 800/QALY (for PEG/RBV plus HCV protease inhibitor). The incremental cost-effectiveness ratio of screening with 3-month LFTs, compared with 6-month LFTs plus a 12-month HCVAb test, was $129 700/QALY (for PEG/RBV alone) and $229 900/QALY (for PEG/RBV plus HCV protease inhibitor). With HCV protease inhibitor-based therapy, screening with 6-month LFTs and a 12-month HCV Ab test was the optimal strategy when the HCV infection incidence was <= 1.25 cases/100 person-years. The 3-month LFT strategy was optimal when the incidence was >1.25 cases/100 person-years.
Conclusions. Screening for acute HCV infection in HIV-infected MSM prolongs life expectancy and is cost-effective. Depending on incidence, regular screening with LFTs, with or without an HCV Ab test, is the optimal strategy.

AB Purpose: To calculated projected second tumor rates and dose to organs at risk (OAR) in patients with benign intracranial meningioma (BM), according to dosimetric comparisons between proton radiotherapy (PRT) and photon radiotherapy (XRT) treatment plans.
Methods and Materials: Ten patients with BM treated at Massachusetts General Hospital during 2006-2010 with PRT were replanned with XRT (intensity-modulated or three-dimensional conformal radiotherapy), optimizing dose to the tumor while sparing OAR. Total dose was 54 Gy in 1.8 Gy per fraction for all plans. We calculated equivalent uniform doses, normal tissue complication probabilities, and whole brain-based estimates of excess risk of radiation-associated intracranial second tumors.
Results: Excess risk of second tumors was significantly lower among PRT compared with XRT plans (1.3 vs. 2.8 per 10,000 patients per year, p < 0.002). Mean equivalent uniform doses were lower among PRT plans for the whole brain (19.0 vs. 22.8 Gy, p < 0.0001), brainstem (23.8 vs. 35.2 Gy, p = 0.004), hippocampi (left, 13.5 vs. 25.6 Gy, p < 0.0001; right, 7.6 vs. 21.8 Gy, p = 0.001), temporal lobes (left, 25.8 vs. 34.6 Gy, p = 0.007; right, 25.8 vs. 32.9 Gy, p = 0.008), pituitary gland (29.2 vs. 37.0 Gy, p = 0.047), optic nerves (left, 28.5 vs. 33.8 Gy, p = 0.04; right, 25.1 vs. 31.1 Gy, p = 0.07), and cochleas (left, 12.2 vs. 15.8 Gy, p = 0.39; right, 1.5 vs. 8.8 Gy, p =0.01). Mean normal tissue complication probability was <1% for all structures and not significantly different between PRT and XRT plans.
Conclusions: Compared with XRT, PRT for BM decreases the risk of RT-associated second tumors by half and delivers significantly lower doses to neurocognitive and critical structures of vision and hearing. (C) 2012 Elsevier Inc.

AB Purpose: Research on patient-reported outcomes (PROs) in rectal cancer is limited. We examined whether dose-volume parameters of the small bowel and large bowel were associated with patient-reported gastrointestinal (GI) symptoms during 5-fluorouracil (5-FU)-based chemoradiation treatment for rectal cancer.
Methods and Materials: 66 patients treated at the Brigham & Women's Hospital or Massachusetts General Hospital between 2006 and 2008 were included. Weekly during treatment, patients completed a questionnaire assessing severity of diarrhea, urgency, pain, cramping, mucus, and tenesmus. The association between dosimetric parameters and changes in overall GI symptoms from baseline through treatment was examined by using Spearman's correlation. Potential associations between these parameters and individual GI symptoms were also explored.
Results: The amount of small bowel receiving at least 15 Gy (V15) was significantly associated with acute symptoms (p = 0.01), and other dosimetric parameters ranging from V5 to V45 also trended toward association. For the large bowel, correlations between dosimetric parameters and overall GI symptoms at the higher dose levels from V25 to V45 did not reach statistical significance (p = 0.1), and a significant association was seen with rectal pain from V15 to V45 (p < 0.01). Other individual symptoms did not correlate with small bowel or large bowel dosimetric parameters.
Conclusions: The results of this study using PROs are consistent with prior studies with physician-assessed acute toxicity, and they identify small bowel V15 as an important predictor of acute GI symptoms during 5-FU-based chemoradiation treatment. A better understanding of the relationship between radiation dosimetric parameters and PROs may allow physicians to improve radiation planning to optimize patient outcomes. (C) 2012 Elsevier Inc.

AB Purpose: In this retrospective study, we report on outcomes and prognostic factors for patients treated with stereotactic radiosurgery (SRS) for breast cancer brain metastases.
Methods and Materials: We identified 132 consecutive patients with breast cancer who were treated with SRS for brain metastases from January 2000 through June 2010. We retrospectively reviewed records of the 51 patients with adequate follow-up data who received SRS as part of the initial management of their brain metastases. Overall survival (OS) and time to central nervous system (CNS) progression from the date of SRS were calculated using the Kaplan-Meier method. Prognostic factors were evaluated using the Cox proportional hazards model.
Results: Triple negative subtype was associated with CNS progression on univariate analysis (hazard ratio [HR] = 5.0, p = 0.008). On multivariate analysis, triple negative subtype (HR = 8.6, p = 0.001), Luminal B subtype (HR = 4.3, p = 0.03), and omission of whole-brain radiation therapy (HR = 3.7, p = 0.02) were associated with CNS progression. With respect to OS, Karnofsky Performance Status (KPS) <= 80% (HR = 2.0, p = 0.04) and progressive extracranial disease (HR = 3.1, p = 0.002) were significant on univariate analysis; KPS <= 80% (HR = 4.1, p = 0.0004), progressive extracranial disease (HR = 6.4, p < 0.0001), and triple negative subtype (HR = 2.9, p = 0.04) were significant on multivariate analysis. Although median survival times were consistent with those predicted by the breast cancer-specific Graded Prognostic Assessment (Breast-GPA) score, the addition of extracranial disease status further separated patient outcomes.
Conclusions: Tumor subtype is associated with risk of CNS progression after SRS for breast cancer brain metastases. In addition to tumor subtype and KPS, which are incorporated into the Breast-GPA, progressive extracranial disease may be an important prognostic factor for OS. (C) 2012 Elsevier Inc.

AB Virtually all patients with Stage I testicular seminoma are cured regardless of postorchiectomy management. For patients treated with adjuvant radiotherapy, late toxicity is a major concern. However, toxicity may be limited by radiotherapy techniques that minimize radiation exposure of healthy normal tissues. This article is an evidence-based review that provides radiotherapy treatment planning recommendations for testicular seminoma. The minority of Stage I patients who choose adjuvant treatment over surveillance may be considered for (1) para-aortic irradiation to 20 Gy in 10 fractions, or (2) carboplatin chemotherapy consisting of area under the curve, AUC = 7 x 1-2 cycles. Two-dimensional radiotherapy based on bony anatomy is a simple and effective treatment for Stage IIA or IIB testicular seminoma. Centers with expertise in vascular and nodal anatomy may consider use of anteroposterior-posteroanterior fields based on three-dimensional conformal radiotherapy instead. For modified dog-leg fields delivering 20 Gy in 10 fractions, clinical studies support placement of the inferior border at the top of the acetabulum. Clinical and nodal mapping studies support placement of the superior border of all radiotherapy fields at the top of the T12 vertebral body. For Stage IIA and IIB patients, an anteroposterior-posteroanterior boost is then delivered to the adenopathy with a 2-cm margin to the block edge. The boost dose consists of 10 Gy in 5 fractions for Stage IIA and 16 Gy in 8 fractions for Stage IIB. Alternatively, bleomycin, etoposide, and cisplatin chemotherapy for 3 cycles or etoposide and cisplatin chemotherapy for 4 cycles may be delivered to Stage IIA or IIB patients (e. g., if they have a horseshoe kidney, inflammatory bowel disease, or a history of radiotherapy).

AB We showed that renal calpain 10, a mitochondrial and cytosolic Ca2+-regulated cysteine protease, is specifically decreased in kidneys of diabetic rats and mice, and is associated with diabetic nephropathy. The goals of this study were to examine renal calpain 10 and mitochondrial dysfunction in streptozotocin-induced hyperglycemic rats and determine the effects of siRNA-mediated knock down of renal calpain 10 on mitochondrial function. Four weeks after streptozotocin injection, calpain 10 protein and mRNA were decreased and calpain 10 substrates accumulated. We detected increased state 2 respiration in isolated renal mitochondria and increased markers of mitochondrial fission and mitophagy. All changes were prevented by daily insulin injection. Compared to scrambled siRNA, calpain 10 siRNA resulted in a marked decrease in renal calpain 10 at 2,5 and 7 days. In concert with the loss of renal calpain 10, calpain 10 substrates accumulated, mitochondrial fusion decreased, mitochondrial fission and mitophagy increased. In summary, insulin-sensitive hyperglycemia induced loss of renal calpain 10 is correlated with renal mitochondrial dysfunction, fission and mitophagy, and specific depletion of renal calpain 10 produces similar mitochondria! defects. These results provide evidence that diabetes-induced renal mitochondrial dysfunction and renal injury may directly result from the loss of renal calpain 10. Published by Elsevier Inc.

AB Multiple neurodegenerative disorders are linked to aberrant phosphorylation of microtubule-associated proteins (MAPs). Protein phosphatase 2A (PP2A) is the major MAP phosphatase; however, little is known about its regulation at microtubules. alpha 4 binds the PP2A catalytic subunit (PP2Ac) and the microtubule-associated E3 ubiquitin ligase MID1, and through unknown mechanisms can both reduce and enhance PP2Ac stability. We show MID1-dependent monoubiquitination of alpha 4 triggers calpain-mediated cleavage and switches alpha 4's activity from protective to destructive, resulting in increased Tau phosphorylation. This regulatory mechanism appears important in MAP-dependent pathologies as levels of cleaved alpha 4 are decreased in Opitz syndrome and increased in Alzheimer disease, disorders characterized by MAP hypophosphorylation and hyperphosphorylation, respectively. These findings indicate that regulated inter-domain cleavage controls the dual functions of alpha 4, and dysregulation of alpha 4 cleavage may contribute to Opitz syndrome and Alzheimer disease.

AB ATP-dependent SWI/SNF chromatin remodeling complexes alter the structure of chromatin at specific loci and facilitate tissue-specific gene regulation during development. Several SWI/SNF subunits are required for cardiogenesis. However, the function and mechanisms of SWI/SNF in mediating cardiac progenitor cell (CPC) differentiation during cardiogenesis are not well understood. Our studies of the SWI/SNF chromatin remodeling complex identified that BAF250a, a regulatory subunit of the SWI/SNF, plays a key role in CPC differentiation. BAF250a ablation in mouse second heart field (SHF) led to trabeculation defects in the right ventricle, ventricular septal defect, persistent truncus arteriosus, reduced myocardial proliferation, and embryonic lethality around E13. Using an embryonic stem cell culture system that models the formation and differentiation of SHF CPCs in vivo, we have shown that BAF250a ablation in CPCs specifically inhibits cardiomyocyte formation. Moreover, BAF250a selectively regulates the expression of key cardiac factors Mef2c, Nkx2.5, and Bmp10 in SHF CPCs. Chromatin immunoprecipitation and DNase I digestion assays indicate that BAF250a regulates gene expression by binding selectively to its target gene promoters and recruiting Brg1, the catalytic subunit of SWI/SNF, to modulate chromatin accessibility. Our results thus identify BAF250a-mediated chromatin remodeling as an essential epigenetic mechanism mediating CPC differentiation.

AB The accessory Sec systems of streptococci and staphylococci mediate the transport of a family of large, serine-rich glycoproteins to the bacterial cell surface. These systems are comprised of SecA2, SecY2, and three core accessory Sec proteins (Asp1-3). In Streptococcus gordonii, transport of the serine-rich glycoprotein GspB requires both a unique 90-residue N-terminal signal peptide and an adjacent 24-residue segment (the AST domain). We used in vivo site-specific photo-cross-linking to identify proteins that interact with the AST domain during transport. To facilitate this analysis, the entire accessory Sec system of S. gordonii was expressed in Escherichia coli. The determinants of GspB trafficking to the accessory Sec system in E. coli matched those in S. gordonii, establishing the validity of this approach. When the photo-cross-linker was placed within the AST domain, the preprotein was found to cross-link to SecA2. Importantly, no cross-linking to SecA was detected. Cross-linking of the N-terminal end of the AST domain to SecA2 occurred regardless of whether Asp1-3 were present. However, cross-linking to the C-terminal end was dependent on the Asps. The combined results indicate that full engagement of the AST domain by SecA2 is modulated by one or more of the Asps, and suggest that this process is important for initiating transport.

AB Cerebral malaria (CM) is the most severe manifestation of clinical malaria syndromes and has a high fatality rate especially in the developing world. Recent studies demonstrated that C5(-/-) mice are resistant to experimental CM (ECM) and that protection was due to the inability to form the membrane attack complex. Unexpectedly, we observed that C4(-/-) and factor B-/- mice were fully susceptible to disease, indicating that activation of the classical or alternative pathways is not required for ECM. C3(-/-) mice were also susceptible to ECM, indicating that the canonical C5 convertases are not required for ECM development and progression. Abrogation of ECM by treatment with anti-C9 antibody and detection of C5a in serum of C3(-/-) mice confirmed that C5 activation occurs in ECM independent of C5 convertases. Our data indicate that activation of C5 in ECM likely occurs via coagulation enzymes of the extrinsic protease pathway.

TI Translocations Disrupting PHF21A in the Potocki-Shaffer-Syndrome Region
Are Associated with Intellectual Disability and Craniofacial Anomalies

AB Potocki-Shaffer syndrome (PSS) is a contiguous gene disorder due to the interstitial deletion of band p11.2 of chromosome 11 and is characterized by multiple exostoses, parietal foramina, intellectual disability (ID), and craniofacial anomalies (CFAs). Despite the identification of individual genes responsible for multiple exostoses and parietal foramina in PSS, the identity of the gene(s) associated with the ID and CFA phenotypes has remained elusive. Through characterization of independent subjects with balanced translocations and supportive comparative deletion mapping of PSS subjects, we have uncovered evidence that the ID and CFA phenotypes are both caused by haploinsufficiency of a single gene, PHF21A, at 11p11.2. PHF21A encodes a plant homeodomain finger protein whose murine and zebrafish orthologs are both expressed in a manner consistent with a function in neurofacial and craniofacial development, and suppression of the latter led to both craniofacial abnormalities and neuronal apoptosis. Along with lysine-specific demethylase 1 (LSD1), PHF21A, also known as BHC80, is a component of the BRAF-histone deacetylase complex that represses target-gene transcription. In lymphoblastoid cell lines from two translocation subjects in whom PHF21A was directly disrupted by the respective breakpoints, we observed derepression of the neuronal gene SCN3A and reduced LSD1 occupancy at the SCN3A promoter, supporting a direct functional consequence of PHF21A haploinsufficiency on transcriptional regulation. Our finding that disruption of PHF21A by translocations in the PSS region is associated with ID adds to the growing list of ID-associated genes that emphasize the critical role of transcriptional regulation and chromatin remodeling in normal brain development and cognitive function.

TI A Homozygous Mutation in KCTD7 Links Neuronal Ceroid Lipofuscinosis to
the Ubiquitin-Proteasome System

AB Neuronal ceroid lipofuscinosis (NCL) is a genetically heterogeneous group of lysosomal diseases that collectively compose the most common Mendelian form of childhood-onset neurodegeneration. It is estimated that similar to 8% of individuals diagnosed with NCL by conservative clinical and histopathologic criteria have been ruled out for mutations in the nine known NCL-associated genes, suggesting that additional genes remain unidentified. To further understand the genetic underpinnings of the NCLs, we performed whole-exome sequencing on DNA samples from a Mexican family affected by a molecularly undefined form of NCL characterized by infantile-onset progressive myoclonic epilepsy (PME), vision loss, cognitive and motor regression, premature death, and prominent NCL-type storage material. Using a recessive model to filter the identified variants, we found a single homozygous variant, c.550C>T in KCTD7, that causes a p.Arg184Cys missense change in potassium channel tetramerization domain-containing protein 7 (KCTD7) in the affected individuals. The mutation was predicted to be deleterious and was absent in over 6,000 controls. The identified variant altered the localization pattern of KCTD7 and abrogated interaction with cullin-3, a ubiquitin-ligase component and known KCTD7 interactor. Intriguingly, murine cerebellar cells derived from a juvenile NCL model (CLN3) showed enrichment of endogenous KCTD7. Whereas KCTD7 mutations have previously been linked to PME without lysosomal storage, this study clearly demonstrates that KCTD7 mutations also cause a rare, infantile-onset NCL subtype designated as CLN14.

AB Certain human pathogens avoid elimination by our immune system by rapidly mutating the surface protein sites targeted by antibody responses, and consequently they tend to be problematic for vaccine development. The behavior described is prominent for a subset of viruses-the highly antigenically diverse viruses-which include HIV, influenza, and hepatitis C viruses. However, these viruses do harbor highly conserved exposed sites, usually associated with function, which can be targeted by broadly neutralizing antibodies. Until recently, not many such antibodies were known, but advances in the field have enabled increasing numbers to be identified. Molecular characterizations of the antibodies and, most importantly, of the sites of vulnerability that they recognize give hope for the discovery of new vaccines and drugs.

AB Eltrombopag (EP) is a small-molecule, nonpeptide thrombopoietin receptor (TPO-R) agonist that has been approved recently for the treatment of thrombocytopenia in patients with chronic immune thrombocytopenic purpura. Prior studies have shown that EP stimulates mega-karyopoiesis in BM cells from patients with acute myeloid leukemia and myelodysplastic syndrome, and the results also suggested that it may inhibit leukemia cell growth. In the present study, we studied the effects of EP on leukemia cell proliferation and the mechanism of its antiproliferative effects. We found that EP leads to a decreased cell division rate, a block in G(1) phase of cell cycle, and increased differentiation in human and murine leukemia cells. Because EP is species specific in that it can only bind TPO-R in human and primate cells, these findings further suggested that the antileukemic effect is independent of TPO-R. We found that treatment with EP leads to a reduction in free intracellular iron in leukemic cells in a dose-dependent manner. Experimental increase of intracellular iron abrogated the antiproliferative and differentiation-inducing effects of EP, demonstrating that its antileukemic effects are mediated through modulation of intracellular iron content. Finally, determination of EP's antileukemic activity in vivo demonstrated its ability to prolong survival in 2 mouse models of leukemia. (Blood. 2012; 120(2): 386-394)

AB In the present study, we re-annotated von Willebrand factor (VWF), assigned its entire sequence to specific modules, and related these modules to structure using electron microscopy (EM). The D domains are assemblies of smaller modules visible as lobes in EM. Modules in the D-domain assemblies include von Willebrand D, 8-cysteine, trypsin inhibitor-like, E or fibronectin type 1-like domains, and a unique D4N module in D4. The D1-D2 prodomain shows 2 large connected assemblies, each containing smaller lobes. The previous B and C regions of VWF are re-annotated as 6 tandem von Willebrand C (VWC) and VWC-like domains. These 6 VWC domains correspond to 6 elongated domains that associate in pairs at acidic pH in the stem region of VWF dimeric bouquets. This correspondence is demonstrated by binding of integrin alpha(IIb)beta(3) to the fourth module seen in EM, VWC4, which bears the VWF Arg-Gly-Asp motif. The C-terminal cystine knot domain dimerizes end-to-end in a manner predicted by homology to TGF-beta and orients approximately perpendicular to the VWC domains in dimeric bouquets. Homologies of domains in VWF to domains in other proteins allow many disulfide bonds to be tentatively assigned, which may have functional implications. (Blood. 2012;120(2):449-458)

TI Socioeconomic Status and Health Communication Inequalities in Japan: A
Nationwide Cross-Sectional Survey
SO PLOS ONE
LA English
DT Article
ID INFORMATION-SEEKING; SOCIAL DETERMINANTS
AB Background: Considerable evidence suggests that communication inequality is one potential mechanism linking social determinants, particularly socioeconomic status, and health inequalities. This study aimed to examine how dimensions of health communication outcomes (health information seeking, self-efficacy, exposure, and trust) are patterned by socioeconomic status in Japan.
Methods: Data of a nationally representative cross-sectional survey of 2,455 people aged 15-75 years in Japan were used for secondary analysis. Measures included socio-demographic characteristics, subjective health, recent health information seeking, self-efficacy in seeking health information, and exposure to and trust in health information from different media.
Results: A total of 1,311 participants completed the questionnaire, giving a response rate of 53.6%. Multivariate logistic regression revealed that education and household income, but not employment, were significantly associated with health information seeking and self-efficacy. Socioeconomic status was not associated with exposure to and trust in health information from mass media, but was significantly associated with health information from healthcare providers and the Internet.
Conclusion: Health communication outcomes were patterned by socioeconomic status in Japan thus demonstrating the prevalence of health communication inequalities. Providing customized exposure to and enhancing the quality of health information by considering social determinants may contribute to addressing social disparities in health in Japan.

AB Background: Elevated levels of biochemical markers of myocardial necrosis have been associated with worsened outcomes in Acute Respiratory Distress Syndrome (ARDS), but there are few prospective data on this relationship. We investigated elevated cardiac troponin T (cTnT) levels and their relationship with outcome in patients with ARDS.
Methods: A prospective cohort study of patients with ARDS was conducted at a tertiary-care academic medical center. Patients had blood taken within 48 hours of ARDS onset and assayed for cTnT. Patients were followed for the outcomes of 60-day mortality, number of organ failures, and days free of mechanical ventilation. Echocardiographic and electrocardiographic (ECG) data were analyzed for signs of myocardial ischemia, infarction, or other myocardial dysfunction.
Results: 177 patients were enrolled, 70 of whom died (40%). 119 patients had detectable cTnT levels (67%). Median cTnT level was 0.03 ng/mL, IQR 0-0.10 ng/mL, and levels were higher among non-survivors (P = .008). Increasing cTnT level was significantly associated with increasing mortality (P = .008). The association between increasing cTnT level and mortality remained significant after adjustment in a multivariate model (HRadj = 1.45, 95% CI 1.17-1.81, P = .001). Elevated cTnT level was also associated with increased number of organ failures (P = .002), decreased number of days free of mechanical ventilation (P = .03), echocardiographic wall motion abnormalities (P = 0.001), and severity of tricuspid regurgitation (P = .04). There was no association between ECG findings of myocardial ischemia or infarction and elevated cTnT.
Conclusions: Elevated cTnT levels are common in patients with ARDS, and are associated with worsened clinical outcomes and certain echocardiographic abnormalities. No association was seen between cTnT levels and ECG evidence of coronary ischemia.

TI Improved Survival with MEK Inhibition in BRAF-Mutated Melanoma
SO NEW ENGLAND JOURNAL OF MEDICINE
LA English
DT Article
ID MUTATIONS; PATHWAY; CANCER; KINASE; RESISTANCE; CRITERIA
AB BACKGROUND
Activating mutations in serine-threonine protein kinase B-RAF (BRAF) are found in 50% of patients with advanced melanoma. Selective BRAF-inhibitor therapy improves survival, as compared with chemotherapy, but responses are often short-lived. In previous trials, MEK inhibition appeared to be promising in this population.
METHODS
In this phase 3 open-label trial, we randomly assigned 322 patients who had metastatic melanoma with a V600E or V600K BRAF mutation to receive either trametinib, an oral selective MEK inhibitor, or chemotherapy in a 2: 1 ratio. Patients received trametinib (2 mg orally) once daily or intravenous dacarbazine (1000 mg per square meter of body-surface area) or paclitaxel (175 mg per square meter) every 3 weeks. Patients in the chemotherapy group who had disease progression were permitted to cross over to receive trametinib. Progression-free survival was the primary end point, and overall survival was a secondary end point.
RESULTS
Median progression-free survival was 4.8 months in the trametinib group and 1.5 months in the chemotherapy group (hazard ratio for disease progression or death in the trametinib group, 0.45; 95% confidence interval [CI], 0.33 to 0.63; P<0.001). At 6 months, the rate of overall survival was 81% in the trametinib group and 67% in the chemotherapy group despite crossover (hazard ratio for death, 0.54; 95% CI, 0.32 to 0.92; P=0.01). Rash, diarrhea, and peripheral edema were the most common toxic effects in the trametinib group and were managed with dose interruption and dose reduction; asymptomatic and reversible reduction in the cardiac ejection fraction and ocular toxic effects occurred infrequently. Secondary skin neoplasms were not observed.
CONCLUSIONS
Trametinib, as compared with chemotherapy, improved rates of progression-free and overall survival among patients who had metastatic melanoma with a BRAF V600E or V600K mutation. (Funded by GlaxoSmithKline; METRIC ClinicalTrials.gov number, NCT01245062.)

AB Auditory hair cells are surrounded on their basolateral aspects by supporting cells, and these two cell types together constitute the sensory epithelium of the organ of Corti, which is the hearing apparatus of the ear. We show here that Lgr5, a marker for adult stem cells, was expressed in a subset of supporting cells in the newborn and adult murine cochlea. Lgr5-expressing supporting cells, sorted by flow cytometry and cultured in a single-cell suspension, compared with unsorted cells, displayed an enhanced capacity for self-renewing neurosphere formation in response to Wnt and were converted to hair cells at a higher (> 10-fold) rate. The greater differentiation of hair cells in the neurosphere assay showed that Lgr5-positive cells had the capacity to act as cochlear progenitor cells, and lineage tracing confirmed that Lgr5-expressing cells accounted for the cells that formed neurospheres and differentiated to hair cells. The responsiveness to Wnt of cells with a capacity for division and sensory cell formation suggests a potential route to new hair cell generation in the adult cochlea.

TRIGEMINAL GANGLION; RECEPTOR EXPRESSION; NEUROPATHIC PAIN; DRG NEURONS;
DIFFERENTIATION; BRN3A
AB Neurons in the mouse dorsal root ganglia (DRGs) are composed of a variety of sensory modalities, such as pain-related nociceptors, itch-related pruriceptors, and thermoceptors. All these neurons are derived from late-born neurons that are initially marked by the expression of the nerve growth factor receptor TrkA. During perinatal and postnatal development, these TrkA lineage neurons are globally segregated into Ret-expressing and TrkA-expressing subtypes, and start to express a variety of sensory receptors and ion channels. The runt domain transcription factor Runx1 plays a pivotal role in controlling these developmental processes, but it remains unclear how it works. Here we showed that the homeodomain transcription factor Tlx3, expressed broadly in DRG neurons, is required to establish most Runx1-dependent phenotypes, including the segregation of TrkA-expressing versus Ret-expressing neurons and the expression of a dozen of sensory channels and receptors implicated in sensing pain, itch and temperature. Expression of Runx1 and Tlx3 is independent of each other at prenatal stages when they first establish the expression of these channels and receptors. Moreover, overexpression of Runx1 plus Tlx3 was able to induce ectopic expression of sensory channels and receptors. Collectively, these studies suggest that genetically Tlx3 acts in combination with Runx1 to control the development of a cohort of nociceptors, thermoceptors, and pruriceptors in mice.

AB Creating new molecules that simultaneously enhance tumor cell killing and permit diagnostic tracking is vital to overcoming the limitations rendering current therapeutic regimens for terminal cancers ineffective. Accordingly, we investigated the efficacy of an innovative new multi-functional targeted anti-cancer molecule, SM7L, using models of the lethal brain tumor Glioblastoma multiforme (GBM). Designed using predictive computer modeling, SM7L incorporates the therapeutic activity of the promising anti-tumor cytokine MDA-7/IL-24, an enhanced secretory domain, and diagnostic domain for non-invasive tracking. In vitro assays revealed the diagnostic domain of SM7L produced robust photon emission, while the therapeutic domain showed marked anti-tumor efficacy and significant modulation of p38MAPK and ERK pathways. In vivo, the unique multi-functional nature of SM7L allowed simultaneous real-time monitoring of both SM7L delivery and anti-tumor efficacy. Utilizing engineered stem cells as novel delivery vehicles for SM7L therapy (SC-SM7L), we demonstrate that SC-SM7L significantly improved pharmacokinetics and attenuated progression of established peripheral and intracranial human GBM xenografts. Furthermore, SC-SM7L anti-tumor efficacy was augmented in vitro and in vivo by concurrent activation of caspase-mediated apoptosis induced by adjuvant SC-mediated S-TRAIL delivery. Collectively, these studies define a promising new approach to treating highly aggressive cancers, including GBM, using the optimized therapeutic molecule SM7L.

TI Vault Nanocapsules as Adjuvants Favor Cell-Mediated over

AB Background: Modifications of adjuvants that induce cell-mediated over antibody-mediated immunity is desired for development of vaccines. Nanocapsules have been found to be viable adjuvants and are amenable to engineering for desired immune responses. We previously showed that natural nanocapsules called vaults can be genetically engineered to elicit Th1 immunity and protection from a mucosal bacterial infection. The purpose of our study was to characterize immunity produced in response to OVA within vault nanoparticles and compare it to another nanocarrier.
Methodology and Principal Findings: We characterized immunity resulting from immunization with the model antigen, ovalbumin (OVA) encased in vault nanocapsules and liposomes. We measured OVA responsive CD8(+) and CD4(+) memory T cell responses, cytokine production and antibody titers in vitro and in vivo. We found that immunization with OVA contain in vaults induced a greater number of anti-OVA CD8(+) memory T cells and production of IFN gamma plus CD4(+) memory T cells. Also, modification of the vault body could change the immune response compared to OVA encased in liposomes.
Conclusions/Significance: These experiments show that vault nanocapsules induced strong anti-OVA CD8(+) and CD4(+) T cell memory responses and modest antibody production, which markedly differed from the immune response induced by liposomes. We also found that the vault nanocapsule could be modified to change antibody isotypes in vivo. Thus it is possible to create a vault nanocapsule vaccine that can result in the unique combination of immunogen-responsive CD8(+) and CD4(+) T cell immunity coupled with an IgG1 response for future development of vault nanocapsule-based vaccines against antigens for human pathogens and cancer.

SLC25A15; ACID; GENE
AB Background: In hyperornithinemia-hyperammonemia-homocitrullinemia (HHH) syndrome, impaired ornithine transport across the mitochondrial membrane causes ornithine accumulation in cytoplasm. The resulting mitochondrial ornithine deficiency leads to reduced clearance of ammonia through the urea cycle. First described in 1969, no long-term follow-up has been reported.
Methods: Four patients were followed up for 11 to 38 y. Diagnosis was made by plasma amino acid analysis using ion exchange chromatography, HPLC orotic acid measurement, and C-14-ornithine incorporation study using cultured fibroblasts. DNA from fibroblasts was amplified and sequenced. Blood ammonia was controlled by restriction of protein intake.
Results: All patients had reduced C-14-ornithine incorporation. Mutation analysis revealed two novel mutations in the ORNT1 gene. Neurologic outcome included memory loss, low IQ tremor, spasticity of extremities, bladder incontinence, and abnormal gait. Neuroimaging revealed subcortical, cerebral and cerebellar atrophy, sparing the basal ganglia. Individual examination showed pyramidal signs, cerebellar signs, paraplegia, movement disorder, dystonia, and epilepsy. One patient had 3 pregnancies, one of which resulted in intrauterine growth retardation.
Conclusions: Our patients expand the clinical phenotype of adults with HHH. Long-term follow-up showed serious neurologic outcomes in all patients; three patients clearly exhibited progression of neurologic dysfunction despite control of hyperammonemia. Intracellular ornithine deficiency may adversely affect brain functions. (C) 2012 Elsevier B.V. All rights reserved.

AB Background-Hemorrhage is associated with ischemic complications in cardiac patients. The nature of this relationship in surgical patients is unknown.
Methods and Results-We examined the association between major perioperative hemorrhage and stroke or myocardial infarction among adults who underwent surgery from 2005 through 2009 at centers participating in the National Surgical Quality Improvement Program. We excluded patients with emergent, trauma-related, transplantation, cardiac, or neurological operations. Major hemorrhage was defined as bleeding necessitating transfusion of >4 U of packed red blood cells or whole blood. Stroke was defined as focal brain dysfunction lasting >= 24 hours from a vascular cause. A diagnosis of myocardial infarction required new ECG Q waves. Outcomes were assessed from surgery until 30 days afterward. Among 651 775 patients who underwent surgery, 5233 (0.80%) experienced major hemorrhage, 1575 (0.24%) developed Q-wave myocardial infarction, and 1321 (0.20%) suffered a stroke. In Cox proportional hazards analyses controlling for vascular risk factors, illness severity, and type of surgery, hemorrhage was independently associated with subsequent stroke (hazard ratio, 2.5; 95% confidence interval, 1.9-3.3) and subsequent Q-wave myocardial infarction (hazard ratio, 2.7; 95% confidence interval, 2.1-3.4). Interaction terms revealed no significant variation in these associations by age, sex, or type of surgery. Our results were robust across multiple sensitivity analyses.
Conclusions-Major perioperative hemorrhage is associated with subsequent stroke and myocardial infarction in patients undergoing noncardiac, nonneurological surgery. This suggests the need for randomized trials to guide perioperative use of antiplatelet drugs, which affect the risk of both bleeding and vascular events. (Circulation. 2012; 126: 207-212.)

AB A fundamental aspect of skeletal myogenesis involves extensive rounds of cell fusion, in which individualmyoblasts are incorporated into growing muscle fibers. Here we demonstrate that N-WASp, a ubiquitous nucleation-promoting factor of branched microfilament arrays, is an essential contributor to skeletal muscle-cell fusion in developing mouse embryos. Analysis both in vivo and in primary satellite-cell cultures, shows that disruption of N-WASp function does not interfere with the program of skeletal myogenic differentiation, and does not affect myoblast motility, morphogenesis and attachment capacity. N-WASp-deficient myoblasts, however, fail to fuse. Furthermore, our analysis suggests that myoblast fusion requires N-WASp activity in both partners of a fusing myoblast pair. These findings reveal a specific role for N-WASp during mammalian myogenesis. WASp-family elements appear therefore to act as universal mediators of the myogenic cell-cell fusion mechanism underlying formation of functional muscle fibers, in both vertebrate and invertebrate species.

AB One of the central goals of human genetics is to discover the genes and pathways driving human traits. To date, most of the common risk alleles discovered through genome-wide association studies (GWAS) map to nonprotein-coding regions. Because of our relatively poorer understanding of this part of the genome, the functional consequences of trait-associated variants pose a considerable challenge. To identify the genes through which risk loci act, we hypothesized that the risk variants are regulatory elements. For each of 12 known risk polymorphisms, we evaluated the correlation between risk allele status and transcript abundance for all annotated protein-coding transcripts within a 1-Mb interval. A total of 103 transcripts were evaluated in 662 prostate tissue samples [normal (n = 407) and tumor (n = 255)] from 483 individuals [European Americans (n = 233), Japanese (n = 127), and African Americans (n = 123)]. In a pooled analysis, 4 of the 12 risk variants were strongly associated with five transcripts (NUDT11, MSMB, NCOA4, SLC22A3, and HNF1B) in histologically normal tissue (P <= 0.001). Although associations were also observed in tumor tissue, they tended to be more attenuated. Previously, we showed that MSMB and NCOA4 participate in prostate cancer pathogenesis. Suppressing the expression of NUDT11, SLC22A3, and HNF1B influences cellular phenotypes associated with tumor-related properties in prostate cancer cells. Taken together, the data suggest that these transcripts contribute to prostate cancer pathogenesis.

AB Nanoscale drug delivery vehicles have been harnessed extensively as carriers for cancer chemotherapeutics. However, traditional pharmaceutical approaches for nanoformulation have been a challenge with molecules that exhibit incompatible physicochemical properties, such as platinum-based chemotherapeutics. Here we propose a paradigm based on rational design of active molecules that facilitate supramolecular assembly in the nanoscale dimension. Using cisplatin as a template, we describe the synthesis of a unique platinum (II) tethered to a cholesterol backbone via a unique monocarboxylato and O -> Pt coordination environment that facilitates nanoparticle assembly with a fixed ratio of phosphatidylcholine and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine- N-[amino (polyethylene glycol)-2000]. The nanoparticles formed exhibit lower IC50 values compared with carboplatin or cisplatin in vitro, and are active in cisplatin-resistant conditions. Additionally, the nanoparticles exhibit significantly enhanced in vivo antitumor efficacy in murine 4T1 breast cancer and in K-Ras(LSL/+/)Pten(fl/fl) ovarian cancer models with decreased systemic- and nephro-toxicity. Our results indicate that integrating rational drug design and supramolecular nanochemistry can emerge as a powerful strategy for drug development. Furthermore, given that platinum-based chemotherapeutics form the frontline therapy for a broad range of cancers, the increased efficacy and toxicity profile indicate the constructed nanostructure could translate into a nextgeneration platinum-based agent in the clinics.

AB Antiangiogenesis therapy has become a vital part of the armamentarium against cancer. Hypertension is a dose-limiting toxicity for VEGF inhibitors. Thus, there is a pressing need to address the associated adverse events so these agents can be better used. The hypertension may be mediated by reduced NO bioavailability resulting from VEGF inhibition. We proposed that the hypertension may be prevented by coadministration with endostatin (ES), an endogenous angiogenesis inhibitor with antitumor effects shown to increase endothelial NO production in vitro. We determined that Fc-conjugated ES promoted NO production in endothelial and smooth muscle cells. ES also lowered blood pressure in normotensive mice and prevented hypertension induced by anti-VEGF antibodies. This effect was associated with higher circulating nitrate levels and was absent in eNOS-knockout mice, implicating a NO-mediated mechanism. Retrospective study of patients treated with ES in a clinical trial revealed a small but significant reduction in blood pressure, suggesting that the findings may translate to the clinic. Coadministration of ES with VEGF inhibitors may offer a unique strategy to prevent drug-related hypertension and enhance antiangiogenic tumor suppression.

AB ABCB6 is a member of the adenosine triphosphate (ATP)-binding cassette family of transporter proteins that is increasingly recognized as a relevant physiological and therapeutic target. Evaluation of modulators of ABCB6 activity would pave the way toward a more complete understanding of the significance of this transport process in tumor cell growth, proliferation and therapy-related drug resistance. In addition, this effort would improve our understanding of the function of ABCB6 in normal physiology with respect to heme biosynthesis, and cellular adaptation to metabolic demand and stress responses. To search for modulators of ABCB6, we developed a novel cell-based approach that, in combination with flow cytometric high-throughput screening (HTS), can be used to identify functional modulators of ABCB6. Accumulation of protoporphyrin, a fluorescent molecule, in wild-type ABCB6 expressing K562 cells, forms the basis of the HTS assay. Screening the Prestwick Chemical Library employing the HTS assay identified four compounds, benzethonium chloride, verteporfin, tomatine hydrochloride and piperlongumine, that reduced ABCB6 mediated cellular porphyrin levels. Validation of the identified compounds employing the hemin-agarose affinity chromatography and mitochondrial transport assays demonstrated that three out of the four compounds were capable of inhibiting ABCB6 mediated hemin transport into isolated mitochondria. However, only verteporfin and tomatine hydrochloride inhibited ABCB6's ability to compete with hemin as an ABCB6 substrate. This assay is therefore sensitive, robust, and suitable for automation in a high-throughput environment as demonstrated by our identification of selective functional modulators of ABCB6. Application of this assay to other libraries of synthetic compounds and natural products is expected to identify novel modulators of ABCB6 activity.

AB Filamins are important actin cross-linking proteins implicated in scaffolding, membrane stabilization and signal transduction, through interaction with ion channels, receptors and signaling proteins. Here we report the physical and functional interaction between filamins and polycystin-2, a TRP-type cation channel mutated in 10-15% patients with autosomal dominant polycystic kidney disease. Yeast two-hybrid and GST pull-down experiments demonstrated that the C-termini of filamin isoforms A, B and C directly bind to both the intracellular N- and C-termini of polycystin-2. Reciprocal co-immunoprecipitation experiments showed that endogenous polycystin-2 and filamins are in the same complexes in renal epithelial cells and human melanoma A7 cells. We then examined the effect of filamin on polycystin-2 channel function by electrophysiology studies with a lipid bilayer reconstitution system and found that filamin-A substantially inhibits polycystin-2 channel activity. Our study indicates that filamins are important regulators of polycystin-2 channel function, and further links actin cytoskeletal dynamics to the regulation of this channel protein.

AB Purpose
Gemcitabine plus cisplatin is active in malignant mesothelioma (MM), although single-arm phase II trials have reported variable outcomes. Vascular endothelial growth factor (VEGF) inhibitors have activity against MM in preclinical models. We added the anti-VEGF antibody bevacizumab to gemcitabine/cisplatin in a multicenter, double-blind, placebo-controlled randomized phase II trial in patients with previously untreated, unresectable MM.
Patients and Methods
Eligible patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 and no thrombosis, bleeding, or major blood vessel invasion. The primary end point was progression-free survival (PFS). Patients were stratified by ECOG performance status (0 v 1) and histologic subtype (epithelial v other). Patients received gemcitabine 1,250 mg/m(2) on days 1 and 8 every 21 days, cisplatin 75 mg/m(2) every 21 days, and bevacizumab 15 mg/kg or placebo every 21 days for six cycles, and then bevacizumab or placebo every 21 days until progression.
Results
One hundred fifteen patients were enrolled at 11 sites; 108 patients were evaluable. Median PFS time was 6.9 months for the bevacizumab arm and 6.0 months for the placebo arm (P = .88). Median overall survival (OS) times were 15.6 and 14.7 months in the bevacizumab and placebo arms, respectively (P = .91). Partial response rates were similar (24.5% for bevacizumab v 21.8% for placebo; P = .74). A higher pretreatment plasma VEGF concentration (n = 56) was associated with shorter PFS (P = .02) and OS (P = .0066), independent of treatment arm. There were no statistically significant differences in toxicity of grade 3 or greater.
Conclusion
The addition of bevacizumab to gemcitabine/cisplatin in this trial did not significantly improve PFS or OS in patients with advanced MM.

AB Purpose
Attention to patients' religious and spiritual needs is included in national guidelines for quality end-of-life care, but little data exist to guide spiritual care.
Patients and Methods
The Religion and Spirituality in Cancer Care Study is a multi-institution, quantitative-qualitative study of 75 patients with advanced cancer and 339 cancer physicians and nurses. Patients underwent semistructured interviews, and care providers completed a Web-based survey exploring their perspectives on the routine provision of spiritual care by physicians and nurses. Theme extraction was performed following triangulated procedures of interdisciplinary analysis. Multivariable ordinal logistic regression models assessed relationships between participants' characteristics and attitudes toward spiritual care.
Results
The majority of patients (77.9%), physicians (71.6%), and nurses (85.1%) believed that routine spiritual care would have a positive impact on patients. Only 25% of patients had previously received spiritual care. Among patients, prior spiritual care (adjusted odds ratio [AOR], 14.65; 95% CI, 1.51 to 142.23), increasing education (AOR, 1.26; 95% CI, 1.06 to 1.49), and religious coping (AOR, 4.79; 95% CI, 1.40 to 16.42) were associated with favorable perceptions of spiritual care. Physicians held more negative perceptions of spiritual care than patients (P < .001) and nurses (P = .008). Qualitative analysis identified benefits of spiritual care, including supporting patients' emotional well-being and strengthening patient-provider relationships. Objections to spiritual care frequently related to professional role conflicts. Participants described ideal spiritual care to be individualized, voluntary, inclusive of chaplains/clergy, and based on assessing and supporting patient spirituality.
Conclusion
Most patients with advanced cancer, oncologists, and oncology nurses value spiritual care. Themes described provide an empirical basis for engaging spiritual issues within clinical care.

AB Purpose
Despite efforts to intensify chemotherapy, survival for patients with metastatic osteosarcoma remains poor. Overexpression of human epidermal growth factor receptor 2 (HER2) in osteosarcoma has been shown to predict poor therapeutic response and decreased survival. This study tests the safety and feasibility of delivering biologically targeted therapy by combining trastuzumab with standard chemotherapy in patients with metastatic osteosarcoma and HER2 overexpression.
Patients and Methods
Among 96 evaluable patients with newly diagnosed metastatic osteosarcoma, 41 had tumors that were HER2-positive by immunohistochemistry. All patients received chemotherapy with cisplatin, doxorubicin, methotrexate, ifosfamide, and etoposide. Dexrazoxane was administered with doxorubicin to minimize the risk of cardiotoxicity from treatment with trastuzumab and anthracycline. Only patients with HER2 overexpression received concurrent therapy with trastuzumab given for 34 consecutive weeks.
Results
The 30-month event-free and overall survival rates for patients with HER2 overexpression treated with chemotherapy and trastuzumab were 32% and 59%, respectively. For patients without HER2 overexpression, treated with chemotherapy alone, the 30-month event-free and overall survival rates were 32% and 50%, respectively. There was no clinically significant short-term cardiotoxicity in patients treated with trastuzumab and doxorubicin.
Conclusion
Despite intensive chemotherapy plus trastuzumab for patients with HER2-positive disease, the outcome for all patients was poor, with no significant difference between the HER2-positive and HER2-negative groups. Although our findings suggest that trastuzumab can be safely delivered in combination with anthracycline-based chemotherapy and dexrazoxane, its therapeutic benefit remains uncertain. Definitive assessment of trastuzumab's potential role in treating osteosarcoma would require a randomized study of patients with HER2-positive disease.

AB Objectives The purpose of this study was to conduct a meta-analysis to examine an invasive or conservative strategy in diabetic versus nondiabetic patients.
Background Diabetic patients are at increased risk of cardiovascular events after an acute coronary syndrome, yet it remains unknown whether they derive enhanced benefit from an invasive strategy.
Methods Randomized trials comparing an invasive versus conservative treatment strategy were identified. The prevalence of cardiovascular events through 12 months was reported for each trial, stratified by diabetes mellitus status and randomized treatment strategy. Relative risk (RR) ratios and absolute risk reductions were combined using random-effects models.
Results Data were combined across 9 trials comprising 9,904 subjects of whom 1,789 (18.1%) had diabetes mellitus. The RRs for death, nonfatal myocardial infarction (MI), or rehospitalization with an acute coronary syndrome for an invasive versus conservative strategy were similar between diabetic patients (RR: 0.87; 95% confidence interval [CI]: 0.73 to 1.03) and nondiabetic patients (RR: 0.86; 95% CI: 0.70 to 1.06; p interaction = 0.83). An invasive strategy reduced nonfatal MI in diabetic patients (RR: 0.71; 95% CI: 0.55 to 0.92), but not in nondiabetic patients (RR: 0.98; 95% CI: 0.74 to 1.29; p interaction = 0.09). The absolute risk reduction in MI with an invasive strategy was greater in diabetic than nondiabetic patients (absolute risk reduction: 3.7% vs. 0.1%; p interaction = 0.02). There were no differences in death or stroke between groups (p interactions 0.68 and 0.20, respectively).
Conclusions An early invasive strategy yielded similar RR reductions in overall cardiovascular events in diabetic and nondiabetic patients. However, an invasive strategy appeared to reduce recurrent nonfatal MI to a greater extent in diabetic patients. These data support the updated guidelines that recommend an invasive strategy for patients with diabetes mellitus and non-ST-segment elevation acute coronary syndromes.

AB Rab31 is a member of the Ras superfamily of small GTPases that has been linked to poor outcomes in patients with breast cancer. The MUC1-C oncoprotein is aberrantly overexpressed in most human breast cancers and also confers a poor prognosis. The present results demonstrate that MUC1-C induces Rab31 expression in estrogen receptor positive (ER+) breast cancer cells. We show that MUC1-C forms a complex with estrogen receptor alpha (ER alpha) on the Rab31 promoter and activates Rab31 gene transcription in an estrogen-dependent manner. In turn, Rab31 contributes to the upregulation of MUC1-C abundance in breast cancer cells by attenuating degradation of MUC1-C in lysosomes. Expression of an inactive Rab31(S20N) mutant in nonmalignant breast epithelial cells confirmed that Rab31 regulates MUC1-C expression. The functional significance of the MUC1-C/Rab31 interaction is supported by the demonstration that Rab31 confers the formation of mammospheres by a MUC1-C-dependent mechanism. Analysis of microarray databases further showed that (i) Rab31 is expressed at higher levels in breast cancers as compared to that in normal breast tissues, (ii) MUC1+ and ER+ breast cancers have increased levels of Rab31 expression, and (iii) patients with Rab31-positive breast tumors have a significantly decreased ten-year overall survival as compared to those with Rab31-negative tumors. These findings indicate that MUC1-C and Rab31 function in an autoinductive loop that contributes to overexpression of MUC1-C in breast cancer cells.

AB Background: The National Quality Forum (NQF) has endorsed a performance measure designed to increase imaging efficiency for the evaluation of pulmonary embolism (PE) in the emergency department (ED). To our knowledge, no published data have examined the effect of patient-level predictors on performance.
Methods: To quantify the prevalence of avoidable imaging in ED patients with suspected PE, we performed a prospective, multicenter observational study of ED patients evaluated for PE from 2004 through 2007 at 11 US EDs. Adult patients tested for PE were enrolled, with data collected in a standardized instrument. The primary outcome was the proportion of imaging that was potentially avoidable according to the NQF measure. Avoidable imaging was defined as imaging in a patient with low pretest probability for PE, who either did not have a D-dimer test ordered or who had a negative D-dimer test result. We performed subanalyses testing alternative pretest probability cutoffs and imaging definitions on measure performance as well as a secondary analysis to identify factors associated with inappropriate imaging. chi(2) Test was used for bivariate analysis of categorical variables and multivariable logistic regression for the secondary analysis.
Results: We enrolled 5940 patients, of whom 4113 (69%) had low pretest probability of PE. Imaging was performed in 2238 low-risk patients (38%), of whom 811 had no D-dimer testing, and 394 had negative D-dimer test results. Imaging was avoidable, according to the NQF measure, in 1205 patients (32%; 95% CI, 31%-34%). Avoidable imaging owing to not ordering a D-dimer test was associated with age (odds ratio [OR], 1.15 per decade; 95% CI, 1.10-1.21). Avoidable imaging owing to imaging after a negative D-dimer test result was associated with inactive malignant disease (OR, 1.66; 95% CI, 1.11-2.49).
Conclusions: One-third of imaging performed for suspected PE may be categorized as avoidable. Improving adherence to established diagnostic protocols is likely to result in significantly fewer patients receiving unnecessary irradiation and substantial savings.

AB Image-guided alignment procedures in radiotherapy aim at minimizing discrepancies between the planned and the real patient setup. For that purpose, we developed a 2D/3D approach which rigidly registers a computed tomography (CT) with two x-rays by maximizing the agreement in pixel intensity between the x-rays and the corresponding reconstructed radiographs from the CT. Moreover, the algorithm selects regions of interest (masks) in the x-rays based on 3D segmentations from the pre-planning stage. For validation, orthogonal x-ray pairs from different viewing directions of 80 pelvic cone-beam CT (CBCT) raw data sets were used. The 2D/3D results were compared to corresponding standard 3D/3D CBCT-to-CT alignments. Outcome over 8400 2D/3D experiments showed that parametric errors in root mean square were <0.18 degrees (rotations) and <0.73 mm (translations), respectively, using rank correlation as intensity metric. This corresponds to a mean target registration error, related to the voxels of the lesser pelvis, of <2mm in 94.1% of the cases. From the results we conclude that 2D/3D registration based on sequentially acquired orthogonal x-rays of the pelvis is a viable alternative to CBCT-based approaches if rigid alignment on bony anatomy is sufficient, no volumetric intra-interventional data set is required and the expected error range fits the individual treatment prescription.

TI Implications of functional similarity for gene regulatory interactions

AB If one gene regulates another, those two genes are likely to be involved in many of the same biological functions. Conversely, shared biological function may be suggestive of the existence and nature of a regulatory interaction. With this in mind, we develop a measure of functional similarity between genes based on annotations made to the Gene Ontology in which the magnitude of their functional relationship is also indicative of a regulatory relationship. In contrast to other measures that have previously been used to quantify the functional similarity between genes, our measure scales the strength of any shared functional annotation by the frequency of that function's appearance across the entire set of annotations. We apply our method to both Escherichia coli and Saccharomyces cerevisiae gene annotations and find that the strength of our scaled similarity measure is more predictive of known regulatory interactions than previously published measures of functional similarity. In addition, we observe that the strength of the scaled similarity measure is correlated with the structural importance of links in the known regulatory network. By contrast, other measures of functional similarity are not indicative of any structural importance in the regulatory network. We therefore conclude that adequately adjusting for the frequency of shared biological functions is important in the construction of a functional similarity measure aimed at elucidating the existence and nature of regulatory interactions. We also compare the performance of the scaled similarity with a high-throughput method for determining regulatory interactions from gene expression data and observe that the ontology-based approach identifies a different subset of regulatory interactions compared with the gene expression approach. We show that combining predictions from the scaled similarity with those from the reconstruction algorithm leads to a significant improvement in the accuracy of the reconstructed network.

AB Fanconi anemia (FA) is an inherited DNA repair deficiency syndrome. FA patients undergo progressive bone marrow failure (BMF) during childhood, which frequently requires allogeneic hematopoietic stem cell transplantation. The pathogenesis of this BMF has been elusive to date. Here we found that FA patients exhibit a profound defect in hematopoietic stem and progenitor cells (HSPCs) that is present before the onset of clinical BMF. In response to replicative stress and unresolved DNA damage, p53 is hyperactivated in FA cells and triggers a late p21(Cdkn1a)-dependent G0/G1 cell-cycle arrest. Knockdown of p53 rescued the HSPC defects observed in several in vitro and in vivo models, including human FA or FA-like cells. Taken together, our results identify an exacerbated p53/p21 "physiological" response to cellular stress and DNA damage accumulation as a central mechanism for progressive HSPC elimination in FA patients, and have implications for clinical care.

AB Although human induced pluripotent stem cells (hiPSCs) have enormous potential in regenerative medicine, their epigenetic variability suggests that some lines may not be suitable for human therapy. There are currently few benchmarks for assessing quality. Here we show that X-inactivation markers can be used to separate hiPSC lines into distinct epigenetic classes and that the classes are phenotypically distinct. Loss of XIST expression is strongly correlated with upregulation of X-linked oncogenes, accelerated growth rate in vitro, and poorer differentiation in vivo. Whereas differences in X-inactivation potential result in epigenetic variability of female hiPSC lines, male hiPSC lines generally resemble each other and do not overexpress the oncogenes. Neither physiological oxygen levels nor HDAC inhibitors offer advantages to culturing female hiPSC lines. We conclude that female hiPSCs may be epigenetically less stable in culture and caution that loss of XIST may result in qualitatively less desirable stem cell lines.

AB Cellular wound healing, enabling the repair of membrane damage, is ubiquitous in eukaryotes. One aspect of the wound healing response is the redirection of a polarized cytoskeleton and the secretory machinery to the damage site. Although there has been recent progress in identifying conserved proteins involved in wound healing, the mechanisms linking these components into a coherent response are not defined. Using laser damage in budding yeast, we demonstrate that local cell wall/membrane damage triggers the dispersal of proteins from the site of polarized growth, enabling their accumulation at the wound. We define a protein-kinase-C-dependent mechanism that mediates the destruction of the formin Bni1 and the exocyst component Sec3. This degradation is essential to prevent competition between the site of polarized growth and the wound. Mechanisms to overcome competition from a preexisting polarized cytoskeleton may be a general feature of effective wound healing in polarized cells.

AB As a first step toward understanding how rare variants contribute to risk for complex diseases, we sequenced 15,585 human protein-coding genes to an average median depth of 111x in 2440 individuals of European (n = 1351) and African (n = 1088) ancestry. We identified over 500,000 single-nucleotide variants (SNVs), the majority of which were rare (86% with a minor allele frequency less than 0.5%), previously unknown (82%), and population-specific (82%). On average, 2.3% of the 13,595 SNVs each person carried were predicted to affect protein function of similar to 313 genes per genome, and similar to 95.7% of SNVs predicted to be functionally important were rare. This excess of rare functional variants is due to the combined effects of explosive, recent accelerated population growth and weak purifying selection. Furthermore, we show that large sample sizes will be required to associate rare variants with complex traits.

AB Tumors exhibit numerous recurrent hemizygous focal deletions that contain no known tumor suppressors and are poorly understood. To investigate whether these regions contribute to tumorigenesis, we searched genetically for genes with cancer-relevant properties within these hemizygous deletions. We identified STOP and GO genes, which negatively and positively regulate proliferation, respectively. STOP genes include many known tumor suppressors, whereas GO genes are enriched for essential genes. Analysis of their chromosomal distribution revealed that recurring deletions preferentially overrepresent STOP genes and underrepresent GO genes. We propose a hypothesis called the cancer gene island model, whereby gene islands encompassing high densities of STOP genes and low densities of GO genes are hemizygously deleted to maximize proliferative fitness through cumulative haploinsufficiencies. Because hundreds to thousands of genes are hemizygously deleted per tumor, this mechanism may help to drive tumorigenesis across many cancer types.

AB Multiple myeloma (MM) is a plasma cell dyscrasia characterized by the presence of multiple myelomatous "omas" throughout the skeleton, indicating that there is continuous trafficking of tumor cells to multiple areas in the bone marrow niches. MM may therefore represent one of the best models to study cell trafficking or cell metastasis. The process of cell metastasis is described as a multistep process, the invasion-metastasis cascade. This involves cell invasion, intravasation into nearby blood vessels, passage into the circulation, followed by homing into predetermined distant tissues, the formation of new foci of micrometastases, and finally the growth of micrometastasis into macroscopic tumors. This review discusses the significant advances that have been discovered in the complex process of invasion-metastasis in epithelial carcinomas and cell trafficking in hematopoietic stem cells and how this process relates to progression in MM. This progression is mediated by clonal intrinsic factors that mediate tumor invasiveness as well as factors present in the tumor microenvironment that are permissive to oncogenic proliferation. Therapeutic agents that target the different steps of cell dissemination and progression are discussed. Despite the significant advances in the treatment of MM, better therapeutic agents that target this metastatic cascade are urgently needed. (Blood. 2012;120(1):20-30)

AB One of the manifestations of X-linked lymphoproliferative disease (XLP) is progressive agammaglobulinemia, caused by the absence of a functional signaling lymphocyte activation molecule (SLAM)-associated protein (SAP) in T, invariant natural killer T (NKT) cells and NK cells. Here we report that alpha-galactosylceramide (alpha GalCer) activated NKT cells positively regulate antibody responses to haptenated protein antigens at multiple checkpoints, including germinal center formation and affinity maturation. Whereas NKT cell-dependent B cell responses were absent in SAP(-/-). B6 mice that completely lack NKT cells, the small number of SAP-deficient NKT cells in SAP(-/-). BALB/c mice adjuvated antibody production, but not the germinal center reaction. To test the hypothesis that SAP-deficient NKT cells can facilitate humoral immunity, SAP was deleted after development in SAP(fl/fl).tgCreERT2. B6 mice. We find that NKT cell intrinsic expression of SAP is dispensable for noncognate helper functions, but is critical for providing cognate help to antigen-specific B cells. These results demonstrate that SLAM-family receptor-regulated cell-cell interactions are not limited to T-B cell conjugates. We conclude that in the absence of SAP, several routes of NKT cell-mediated antibody production are still accessible. The latter suggests that residual NKT cells in XLP patients might contribute to variations in dysgam-maglobulinemia. (Blood. 2012;120(1):122-129)

AB There has been recent controversy as to whether platelet alpha-granules represent a single granule population or are composed of different subpopulations that serve discrete functions. To address this question, we evaluated the localization of vesicle-associated membrane proteins (VAMPs) in spread platelets to determine whether platelets actively sort a specific subpopulation of alpha-granules to the periphery during spreading. Immunofluorescence microscopy demonstrated that granules expressing VAMP-3 and VAMP-8 localized to the central granulomere of spread platelets along with the granule cargos von Willebrand factor and serotonin. In contrast, alpha-granules expressing VAMP-7 translocated to the periphery of spread platelets along with the granule cargos TIMP2 and VEFG. Time-lapse microscopy demonstrated that alpha-granules expressing VAMP-7 actively moved from the granulomere to the periphery during spreading. Platelets from a patient with gray platelet syndrome lacked alpha-granules and demonstrated only minimal spreading. Similarly, spreading was impaired in platelets obtained from Unc13d(Jinx) mice, which are deficient in Munc13-4 and have an exocytosis defect. These studies identify a new alpha-granule subtype expressing VAMP-7 that moves to the periphery during spreading, supporting the premise that alpha-granules are heterogeneous and demonstrating that granule exocytosis is required for platelet spreading.

AB Clinical practice guidelines are one of the foundations of efforts to improve health care. In 1999, we authored a paper about methods to develop guidelines. Since it was published, the methods of guideline development have progressed both in terms of methods and necessary procedures and the context for guideline development has changed with the emergence of guideline clearing houses and large scale guideline production organisations (such as the UK National Institute for Health and Clinical Excellence). It therefore seems timely to, in a series of three articles, update and extend our earlier paper. In this first paper we discuss: the target audience(s) for guidelines and their use of guidelines; identifying topics for guidelines; guideline group composition (including consumer involvement) and the processes by which guideline groups function and the important procedural issue of managing conflicts of interest in guideline development.

POLYMORPHISMS
AB Background: Long-term lung allograft survival is limited by bronchiolitis obliterans syndrome (BOS). Mannose binding lectin (MBL) belongs to the innate immune system, participates in complement activation, and may predispose to graft rejection. We investigated mannose binding (MBL) during cold ischemia and in tissue samples from explanted lungs with BOS, and assessed MBL and complement proteins in plasma post-lung transplantation relative to BOS staging.
Methods: MBL was detected by immunohistochemistry lung tissue at the time of cold ischemia and in samples with BOS. MBL was assayed in the peripheral blood of 66 lung transplant patients transplanted between 1990-2007.
Results: MBL localized to vasculature and basement membrane during cold ischemia and BOS. Patients further out post-lung transplant > 5 years (n = 33), had significantly lower levels of MBL in the blood compared to lung transplant patients < 5 years with BOS Op-3 (n = 17), 1738 +/- 250 ng/ml vs 3198 +/- 370 ng/ml, p = 0.027, and similar levels to lung transplant patients < 5 years with BOS 0 (n = 16), 1738 +/- 250 ng/ml vs 1808 +/- 345 ng/ml. MBL levels in all BOS 0 (n = 30) vs. all BOS Op-3 (n = 36) were 1378 +/- 275 ng/ml vs. 2578 +/- 390 ng/ml, p = 0.001, respectively. C3 plasma levels in BOS 0 (n = 30) vs. BOS Op-3 (n = 36) were 101 +/- 19.8 mg/ml vs. 114 +/- 25.2 mg/ml, p = 0.024, respectively.
Conclusions: MBL localizes within the lung during graft ischemia and BOS, higher levels of plasma MBL are associated with BOS Op-3 and < 5 years post-transplant, and higher level of plasma complement protein C3 was associated with BOS Op-3 clinical status. MBL may serve as a biomarker for poorer outcome post-lung transplantation.

AB Topographically organized maps of the sensory receptor epithelia are regarded as cornerstones of cortical organization as well as valuable readouts of diverse biological processes ranging from evolution to neural plasticity. However, maps are most often derived from multi-unit activity recorded in the thalamic input layers of anesthetized animals using near-threshold stimuli. Less distinct topography has been described by studies that deviated from the formula above, which brings into question the generality of the principle. Here, we explicitly compared the strength of tonotopic organization at various depths within core and belt regions of the auditory cortex using electrophysiological measurements ranging from single units to delta-band local field potentials (LFP) in the awake and anesthetized mouse. Unit recordings in the middle cortical layers revealed a precise tonotopic organization in core, but not belt, regions of auditory cortex that was similarly robust in awake and anesthetized conditions. In core fields, tonotopy was degraded outside the middle layers or when LFP signals were substituted for unit activity, due to an increasing proportion of recording sites with irregular tuning for pure tones. However, restricting our analysis to clearly defined receptive fields revealed an equivalent tonotopic organization in all layers of the cortical column and for LFP activity ranging from gamma to theta bands. Thus, core fields represent a transition between topographically organized simple receptive field arrangements that extend throughout all layers of the cortical column and the emergence of nontonotopic representations outside the input layers that are further elaborated in the belt fields.

AB Broadband transient sounds, such as clicks and consonants, activate a traveling wave in the cochlea. This wave evokes firing in auditory nerve fibers that are tuned to high frequencies several milliseconds earlier than in fibers tuned to low frequencies. Despite this substantial traveling wave delay, octopus cells in the brainstem receive broadband input and respond to clicks with submillisecond temporal precision. The dendrites of octopus cells lie perpendicular to the tonotopically organized array of auditory nerve fibers, placing the earliest arriving inputs most distally and the latest arriving closest to the soma. Here, we test the hypothesis that the topographic arrangement of synaptic inputs on dendrites of octopus cells allows octopus cells to compensate the traveling wave delay. We show that in mice the full cochlear traveling wave delay is 1.6 ms. Because the dendrites of each octopus cell spread across approximately one-third of the tonotopic axis, a click evokes a soma-directed sweep of synaptic input lasting 0.5 ms in individual octopus cells. Morphologically and biophysically realistic, computational models of octopus cells show that soma-directed sweeps with durations matching in vivo measurements result in the largest and sharpest somatic EPSPs. A low input resistance and activation of a low-voltage-activated potassium conductance that are characteristic of octopus cells are important determinants of sweep sensitivity. We conclude that octopus cells have dendritic morphologies and biophysics tailored to accomplish the precise encoding of broadband transient sounds.

AB Cigarette smoking, nicotine replacement therapy, and smokeless tobacco use during pregnancy are associated with cognitive disabilities later in life in children exposed prenatally to nicotine. The disabilities include attention deficit hyperactivity disorder (ADHD) and conduct disorder. However, the structural and neurochemical bases of these cognitive deficits remain unclear. Using a mouse model we show that prenatal nicotine exposure produces hyperactivity, selective decreases in cingulate cortical volume, and radial thickness, as well as decreased dopamine turnover in the frontal cortex. The hyperactivity occurs in both male and female offspring and peaks during the "active" or dark phase of the light/dark cycle. These features of the mouse model closely parallel the human ADHD phenotype, whether or not the ADHD is associated with prenatal nicotine exposure. A single oral, but not intraperitoneal, administration of a therapeutic equivalent dose (0.75 mg/kg) of methylphenidate decreases the hyperactivity and increases the dopamine turnover in the frontal cortex of the prenatally nicotine exposed mice, once again paralleling the therapeutic effects of this compound in ADHD subjects. Collectively, our data suggest that the prenatal nicotine exposure mouse model has striking parallels to the ADHD phenotype not only in behavioral, neuroanatomical, and neurochemical features, but also with respect to responsiveness of the behavioral phenotype to methylphenidate treatment. The behavioral, neurochemical, and anatomical biomarkers in the mouse model could be valuable for evaluating new therapies for ADHD and mechanistic investigations into its etiology.

AB Parkinson's disease (PD) is a common neurodegenerative disorder caused by genetic and environmental factors that results in degeneration of the nigrostriatal dopaminergic pathway in the brain. We analyzed neural cells generated from induced pluripotent stem cells (iPSCs) derived from PD patients and presymptomatic individuals carrying mutations in the PINK1 (PTEN-induced putative kinase 1) and LRRK2 (leucine-rich repeat kinase 2) genes, and compared them to those of healthy control subjects. We measured several aspects of mitochondrial responses in the iPSC-derived neural cells including production of reactive oxygen species, mitochondrial respiration, proton leakage, and intraneuronal movement of mitochondria. Cellular vulnerability associated with mitochondrial dysfunction in iPSC-derived neural cells from familial PD patients and at-risk individuals could be rescued with coenzyme Q(10), rapamycin, or the LRRK2 kinase inhibitor GW5074. Analysis of mitochondrial responses in iPSC-derived neural cells from PD patients carrying different mutations provides insight into convergence of cellular disease mechanisms between different familial forms of PD and highlights the importance of oxidative stress and mitochondrial dysfunction in this neurodegenerative disease.

AB The ability to detect rare cells (<100 cells/ml whole blood) and obtain quantitative measurements of specific biomarkers on single cells is increasingly important in basic biomedical research. Implementing such methodology for widespread use in the clinic, however, has been hampered by low cell density, small sample sizes, and requisite sample purification. To overcome these challenges, we have developed a microfluidic chip-based micro-Hall detector (mu HD), which can directly measure single, immunomagnetically tagged cells in whole blood. The mu HD can detect single cells even in the presence of vast numbers of blood cells and unbound reactants, and does not require any washing or purification steps. In addition, the high bandwidth and sensitivity of the semiconductor technology used in the mu HD enables high-throughput screening (currently similar to 10(7) cells/min). The clinical use of the mu HD chip was demonstrated by detecting circulating tumor cells in whole blood of 20 ovarian cancer patients at higher sensitivity than currently possible with clinical standards. Furthermore, the use of a panel of magnetic nanoparticles, distinguished with unique magnetization properties and bio-orthogonal chemistry, allowed simultaneous detection of the biomarkers epithelial cell adhesion molecule (EpCAM), human epidermal growth factor receptor 2 (HER2)/neu, and epidermal growth factor receptor (EGFR) on individual cells. This cost-effective, single-cell analytical technique is well suited to perform molecular and cellular diagnosis of rare cells in the clinic.

AB Context Based on limited data, the live attenuated herpes zoster (HZ) vaccine is contraindicated in patients taking anti-tumor necrosis factor (anti-TNF) therapies or other biologics commonly used to treat immune-mediated diseases. The safety and effectiveness of the vaccine are unclear for these patients.
Objective To examine the association between HZ vaccination and HZ incidence within and beyond 42 days after vaccination in patients with selected immune-mediated diseases and in relation to biologics and other therapies used to treat these conditions.
Design, Setting, and Patients Retrospective cohort study of 463 541 Medicare beneficiaries 60 years and older with rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, or inflammatory bowel disease using Medicare claims data from January 1, 2006, through December 31, 2009.
Main Outcome Measures Herpes zoster incidence rate within 42 days after vaccination (a safety concern) and beyond 42 days; hazard ratios estimated using Cox proportional hazards models for HZ comparing vaccinated vs unvaccinated patients.
Results Median duration of follow-up was 2.0 years (interquartile range, 0.8-3.0); 4.0% of patients received HZ vaccine. The overall crude HZ incidence rate was 7.8 cases per 1000 person-years (95% CI, 3.7-16.5) within 42 days after vaccination. The rate among the unvaccinated was 11.6 cases per 1000 person-years (95% CI, 11.4-11.9). Among 633 patients exposed to biologics at the time of vaccination or within the subsequent 42 days, no case of HZ or varicella occurred. After multivariable adjustment, HZ vaccination was associated with a hazard ratio of 0.61 (95% CI, 0.52-0.71) for HZ risk after 42 days.
Conclusions Receipt of HZ vaccine was not associated with a short-term increase in HZ incidence among Medicare beneficiaries with selected immune-mediated diseases, including those exposed to biologics. The vaccine was associated with a lower HZ incidence over a median of 2 years of follow-up. JAMA. 2012; 308(1):43-49 www.jama.com

A fibrin-specific peptide was conjugated with two distinct imaging reporters at the C- and N-termini. In vitro studies demonstrated retention of fibrin affinity and specificity. Imaging studies showed that these probes could detect fibrin over a wide range of probe concentrations by optical, magnetic resonance, and positron emission tomography imaging.

AB Background-We hypothesized that high-sensitivity cardiac troponin (hs-cTn) and its early change are useful in distinguishing acute myocardial infarction (AMI) from acute cardiac noncoronary artery disease.
Methods and Results-In a prospective, international multicenter study, hs-cTn was measured with 3 assays (hs-cTnT, Roche Diagnostics; hs-cTnI, Beckman-Coulter; hs-cTnI Siemens) in a blinded fashion at presentation and serially thereafter in 887 unselected patients with acute chest pain. Accuracy of the combination of presentation values with serial changes was compared against a final diagnosis adjudicated by 2 independent cardiologists. AMI was the adjudicated final diagnosis in 127 patients (15%); cardiac noncoronary artery disease, in 124 (14%). Patients with AMI had higher median presentation values of hs-cTnT (0.113 mu g/L [interquartile range, 0.049-0.246 mu g/L] versus 0.012 mu g/L [interquartile range, 0.006-0.034 mu g/L]; P<0.001) and higher absolute changes in hs-cTnT in the first hour (0.019 mu g/L [interquartile range, 0.007-0.067 mu g/L] versus 0.001 mu g/L [interquartile range, 0-0.003 mu g/L]; P<0.001) than patients with cardiac noncoronary artery disease. Similar findings were obtained with the hs-cTnI assays. Adding changes of hs-cTn in the first hour to its presentation value yielded a diagnostic accuracy for AMI as quantified by the area under the receiver-operating characteristics curve of 0.94 for hs-cTnT (0.92 for both hs-cTnI assays). Algorithms using ST-elevation, presentation values, and changes in hs-cTn in the first hour accurately separated patients with AMI and those with cardiac noncoronary artery disease. These findings were confirmed when the final diagnosis was readjudicated with the use of hs-cTnT values and validated in an independent validation cohort.
Conclusion-The combined use of hs-cTn at presentation and its early absolute change excellently discriminates between patients with AMI and those with cardiac noncoronary artery disease.

AB Background-Ventricular arrhythmias remain a lethal complication of acute coronary syndromes (ACS). However, the incidence and prognosis of sustained ventricular tachycardia/ventricular fibrillation (VT/VF) in contemporary non-ST-segment-elevation (NSTE) ACS populations are not well described.
Methods and Results-We examined the incidence of VT/VF and subsequent survival among 9211 patients enrolled in the Early Glycoprotein IIb/IIIa Inhibition in NSTE ACS (EARLY ACS) trial. The cumulative incidence of VT/VF was 1.5% (n = 141); 0.6% (n = 55) had VT/VF <= 48 hours after enrollment, and 0.9% (n = 86) had VT/VF >48 hours after enrollment. Patients with VT/VF more frequently had prior heart failure, an ejection fraction <30%, and triple-vessel coronary artery disease. Predictors of sustained VT/VF were similar regardless of the timing of VT/VF (<= 48 versus >48 hours). Patients with VT/VF <= 48 hours after enrollment had higher 30-day mortality than those who did not have VT/VF <= 48 hours (13.0% versus 2.2%; adjusted odds ratio, 6.73; 95% confidence interval, 2.68-16.9). The increased risk of death associated with VT/VF <= 48 hours persisted at 1 year. The risk of mortality, relative to patients without VT/VF, was greater for patients with VT/VF <= 48 hours (hazard ratio, 20.70; 95% confidence interval, 15.39-27.85) than for those with earlier VT/VF (hazard ratio, 7.45; 95% confidence interval, 4.60-12.08; P = 0.0003). The frequency of arrhythmic death was higher in patients with VT/VF than in those without VT/VF (26.4% versus 6.9%).
Conclusions-Sustained VT/VF is infrequent after NSTE ACS but is as likely to occur after 48 hours as within the first 48 hours. The marked increase in all-cause death among NSTE ACS patients with both early and late sustained VT/VF raises important considerations for aggressive monitoring beyond 48 hours and interventions to prevent arrhythmic death in these patients.

AB Background-Heart failure with preserved ejection fraction (EF) is a common syndrome, but trends in treatments and outcomes are lacking.
Methods and Results-We analyzed data from 275 hospitals in Get With the Guidelines-Heart Failure from January 2005 to October 2010. Patients were stratified by EF as reduced EF (EF <40% [HF-reduced EF]), borderline EF (40%<= EF<50% [HF-borderline EF]), or preserved (EF >= 50% [HF-preserved EF]). Using multivariable models, we examined trends in therapies and outcomes. Among 110 621 patients, 50% (55 083) had HF-reduced EF, 14% (15 184) had HF-borderline EF, and 36% (40 354) had HF-preserved EF. From 2005 to 2010, the proportion of hospitalizations for HF-preserved EF increased from 33% to 39% (P < 0.0001). In multivariable analyses, use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers at discharge decreased in all EF groups, and beta-blocker use increased. Patients with HF-preserved EF less frequently achieved blood pressure control (adjusted odds ratio, 0.44 versus HF-reduced EF; P < 0.001) and were more likely discharged to skilled nursing (adjusted odds ratio, 1.16 versus HF-reduced EF; P < 0.001). In-hospital mortality for HF-preserved EF decreased from 3.32% in 2005 to 2.35% in 2010 (adjusted odds ratio, 0.89 per year; P = 0.01) but was stable for patients with HF-reduced EF (3.03%-2.83%; adjusted odds ratio, 0.93 per year; P = 0.10).
Conclusions-Hospitalization for HF-preserved EF is increasing relative to HF-reduced EF. Although in-hospital mortality for patients with HF-preserved EF declined over the study period, an important opportunity remains for identifying evidence-based therapies in patients with HF-preserved EF.

AB Members of the RAS small GTPase family regulate cellular responses to extracellular stimuli by mediating the flux through downstream signal transduction cascades. RAS activity is strongly dependent on its subcellular localization and its nucleotide-binding status, both of which are modulated by posttranslational modification. We have determined that RAS is posttranslationally acetylated on lysine 104. Molecular dynamics simulations suggested that this modification affects the conformational stability of the Switch II domain, which is critical for the ability of RAS to interact with guanine nucleotide exchange factors. Consistent with this model, an acetylation-mimetic mutation in K-RAS4B suppressed guanine nucleotide exchange factor-induced nucleotide exchange and inhibited in vitro transforming activity. These data suggest that lysine acetylation is a negative regulatory modification on RAS. Because mutations in RAS family members are extremely common in cancer, modulation of RAS acetylation may constitute a therapeutic approach.

AB Neuronal mechanisms of auditory distance perception are poorly understood, largely because contributions of intensity and distance processing are difficult to differentiate. Typically, the received intensity increases when sound sources approach us. However, we can also distinguish between soft-but-nearby and loud-but-distant sounds, indicating that distance processing can also be based on intensity-independent cues. Here, we combined behavioral experiments, fMRI measurements, and computational analyses to identify the neural representation of distance independent of intensity. In a virtual reverberant environment, we simulated sound sources at varying distances (15-100 cm) along the right-side interaural axis. Our acoustic analysis suggested that, of the individual intensity-independent depth cues available for these stimuli, direct-to-reverberant ratio (D/R) is more reliable and robust than interaural level difference (ILD). However, on the basis of our behavioral results, subjects' discrimination performance was more consistent with complex intensity-independent distance representations, combining both available cues, than with representations on the basis of either D/R or ILD individually. fMRI activations to sounds varying in distance (containing all cues, including intensity), compared with activations to sounds varying in intensity only, were significantly increased in the planum temporale and posterior superior temporal gyrus contralateral to the direction of stimulation. This fMRI result suggests that neurons in posterior nonprimary auditory cortices, in or near the areas processing other auditory spatial features, are sensitive to intensity-independent sound properties relevant for auditory distance perception.

AB Atherosclerosis and insulin resistance are major components of the cardiometabolic syndrome, a global health threat associated with a systemic inflammatory state. Notch signaling regulates tissue development and participates in innate and adaptive immunity in adults. The role of Notch signaling in cardiometabolic inflammation, however, remains obscure. We noted that a high-fat, high-cholesterol diet increased expression of the Notch ligand Delta-like 4 (Dll4) in atheromata and fat tissue in LDL-receptor-deficient mice. Blockade of Dll4-Notch signaling using neutralizing anti-Dll4 antibody attenuated the development of atherosclerosis, diminished plaque calcification, improved insulin resistance, and decreased fat accumulation. These changes were accompanied by decreased macrophage accumulation, diminished expression of monocyte chemoattractant protein-1 (MCP-1), and lower levels of nuclear factor-kappa B (NF-kappa B) activation. In vitro cell culture experiments revealed that Dll4-mediated Notch signaling increases MCP-1 expression via NF-kappa B, providing a possible mechanism for in vivo effects. Furthermore, Dll4 skewed macrophages toward a proinflammatory phenotype ("M1"). These results suggest that Dll4-Notch signaling plays a central role in the shared mechanism for the pathogenesis of cardiometabolic disorders.

AB Even in V1, where neurons have well characterized classical receptive fields (CRFs), it has been difficult to deduce which features of natural scenes stimuli they actually respond to. Forward models based upon CRF stimuli have had limited success in predicting the response of V1 neurons to natural scenes. As natural scenes exhibit complex spatial and temporal correlations, this could be due to surround effects that modulate the sensitivity of the CRF. Here, instead of attempting a forward model, we quantify the importance of the natural scenes surround for awake macaque monkeys by modeling it non-parametrically. We also quantify the influence of two forms of trial to trial variability. The first is related to the neuron's own spike history. The second is related to ongoing mean field population activity reflected by the local field potential (LFP). We find that the surround produces strong temporal modulations in the firing rate that can be both suppressive and facilitative. Further, the LFP is found to induce a precise timing in spikes, which tend to be temporally localized on sharp LFP transients in the gamma frequency range. Using the pseudo R 2 as a measure of model fit, we find that during natural scene viewing the CRF dominates, accounting for 60% of the fit, but that taken collectively the surround, spike history and LFP are almost as important, accounting for 40%. However, overall only a small proportion of V1 spiking statistics could be explained (R-2 similar to 5%), even when the full stimulus, spike history and LFP were taken into account. This suggests that under natural scene conditions, the dominant influence on V1 neurons is not the stimulus, nor the mean field dynamics of the LFP, but the complex, incoherent dynamics of the network in which neurons are embedded.

TI Etanercept, a Widely Used Inhibitor of Tumor Necrosis Factor-alpha

DEATH
AB Background: Visual loss in glaucoma is associated with pathological changes in retinal ganglion cell (RGC) axons and a slow decline in the RGC population. Age and elevated intraocular pressure (IOP) are the main risk factors for glaucomatous loss of vision. Several studies have implicated the proinflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) as a link between elevated IOP and RGC death, but the cellular source of TNF-alpha and its causative role in RGC death remain uncertain. Here, using a rat model of glaucoma, we investigated the source of elevated TNF-alpha and examined whether Etanercept, a TNF-alpha blocker that is in common clinical use for other indications, is protective against RGC death.
Methodology/Principal Findings: Episcleral vein cauterization (EVC) caused intraocular pressure (IOP) to be elevated for at least 28 days. IOP elevation resulted in a dramatic increase in TNF-alpha levels within a few days, axonal degeneration, and a 38% loss of RGCs by 4 weeks. Immunostaining coupled with confocal microscopy showed that OHT induced robust induction of TNF-alpha in Iba-1-positive microglia around the optic nerve head (ONH). Despite persistent elevation of IOP, Etanercept reduced microglial activation, TNF-alpha levels, axon degeneration in the optic nerve, and the loss of RGCs.
Conclusions/Significance: Ocular hypertension (OHT) triggers an inflammatory response characterized by the appearance of activated microglia around the ONH that express TNF-alpha. Blocking TNF-alpha activity with a clinically approved agent inhibits this microglial response and prevents axonal degeneration and loss of RGCs. These findings suggest a new treatment strategy for glaucoma using TNF-alpha antagonists or suppressors of inflammation.

AB Background: Blood pressure, lipid, and glycemic control are essential for reducing cardiovascular disease (CVD) risk. Many health care systems have successfully shifted aspects of chronic disease management, including population-based outreach programs designed to address CVD risk factor control, to non-physicians. The purpose of this study is to evaluate provision of new information to non-physician outreach teams on need for treatment intensification in patients with increased CVD risk.
Methods: Cluster randomized trial (July 1-December 31, 2008) in Kaiser Permanente Northern California registry of members with diabetes mellitus, prior CVD diagnoses and/or chronic kidney disease who were high-priority for treatment intensification: blood pressure >= 140 mmHg systolic, LDL-cholesterol >= 130 mg/dl, or hemoglobin A1c >= 9%; adherent to current medications; no recent treatment intensification). Randomization units were medical center-based outreach teams (4 intervention; 4 control). For intervention teams, priority flags for intensification were added monthly to the registry database with recommended next pharmacotherapeutic steps for each eligible patient. Control teams used the same database without this information. Outcomes included 3-month rates of treatment intensification and risk factor levels during follow-up.
Results: Baseline risk factor control rates were high (82-90%). In eligible patients, the intervention was associated with significantly greater 3-month intensification rates for blood pressure (34.1 vs. 30.6%) and LDL-cholesterol (28.0 vs 22.7%), but not A1c. No effects on risk factors were observed at 3 months or 12 months follow-up. Intervention teams initiated outreach for only 45-47% of high-priority patients, but also for 27-30% of lower-priority patients. Teams reported difficulties adapting prior outreach strategies to incorporate the new information.
Conclusions: Information enhancement did not improve risk factor control compared to existing outreach strategies at control centers. Familiarity with prior, relatively successful strategies likely reduced uptake of the innovation and its potential for success at intervention centers.

AB The incidence of human papillary thyroid cancer (PTC) is increasing and an aggressive subtype of this disease is resistant to treatment with vascular endothelial growth factor receptor 2 (VEGFR2) inhibitor. VEGFR2 promotes angiogenesis by triggering endothelial cell proliferation and migration. However, the molecular mechanisms governing VEGFR2 stability in vivo remain unknown. Additionally, whether VEGFR2 influences PTC cell migration is not clear. We show that the ubiquitin E3 ligase SCF beta-TRCP promotes ubiquitination and destruction of VEGFR2 in a casein kinase I (CKI)-dependent manner. beta-TRCP knockdown or CKI inhibition causes accumulation of VEGFR2, resulting in increased activity of signaling pathways downstream of VEGFR2. beta-TRCP-depleted endothelial cells exhibit enhanced migration and angiogenesis in vitro. Furthermore, beta-TRCP knockdown increased angiogenesis and vessel branching in zebrafish. Importantly, we found an inverse correlation between beta-TRCP protein levels and angiogenesis in PTC. We also show that beta-TRCP inhibits cell migration and decreases sensitivity to the VEGFR2 inhibitor sorafenib in poorly differentiated PTC cells. These results provide a new biomarker that may aid a rational use of tyrosine kinase inhibitors to treat refractory PTC.

TI Self-interference fluorescence microscopy: three dimensional
fluorescence imaging without depth scanning
SO OPTICS EXPRESS

DT Article

AB We present a new method for high-resolution, three-dimensional fluorescence imaging. In contrast to beam-scanning confocal microscopy, where the laser focus must be scanned both laterally and axially to collect a volume, we obtain depth information without the necessity of depth scanning. In this method, the emitted fluorescence is collected in the backward direction and is sent through a phase plate that encodes the depth information into the phase of a spectrally resolved interference pattern. We demonstrate that decoding this phase information allows for depth localization accuracy better than 4 mu m over a 500 mu m depth-of-field. In a high numerical aperture configuration with a much smaller depth of field, a localization accuracy of tens of nanometers can be achieved. This approach is ideally suited for miniature endoscopes, where space limitations at the endoscope tip render depth scanning difficult. We illustrate the potential for 3D visualization of complex biological samples by constructing a three-dimensional volume of the microvasculature of ex vivo murine heart tissue from a single 2D scan.

AB Background: This study aimed to explore the association of MTNR1B genetic variants with gestational plasma glucose homeostasis in pregnant Chinese women.
Methods: A total of 1,985 pregnant Han Chinese women were recruited and evaluated for gestational glucose tolerance status with a two-step approach. The four MTNR1B variants rs10830963, rs1387153, rs1447352, and rs2166706 which had been reported to associate with glucose levels in general non-pregnant populations, were genotyped in these women. Using an additive model adjusted for age and body mass index (BMI), association of these variants with gestational fasting and postprandial plasma glucose (FPG and PPG) levels were analyzed by multiple linear regression; relative risk of developing gestational glucose intolerance was calculated by logistic regression. Hardy-Weinberg Equilibrium was tested by Chi-square and linkage disequilibrium (LD) between these variants was estimated by measures of D' and r(2).
Results: In the pregnant Chinese women, the MTNR1B variant rs10830963, rs1387153, rs2166706 and rs1447352 were shown to be associated with the increased 1 hour PPG level (p = 8.04 x 10(-10), 5.49 x 10(-6), 1.89 x 10(-5) and 0.02, respectively). The alleles were also shown to be associated with gestational glucose intolerance with odds ratios (OR) of 1.64 (p = 8.03 x 10(-11)), 1.43 (p = 1.94 x 10(-6)), 1.38 (p = 1.63 x 10(-5)) and 1.24 (p = 0.007), respectively. MTNR1B rs1387153, rs2166706 were shown to be associated with gestational FPG levels (p = 0.04). Our data also suggested that, the LD pattern of these variants in the studied women conformed to that in the general populations: rs1387153 and rs2166706 were in high LD, they linked moderately with rs10830963, but might not linked with rs1447352; rs10830963 might not link with rs1447352, either. In addition, the MTNR1B variants were not found to be associated with any other traits tested.
Conclusions: The MTNR1B is likely to be involved in the regulation of glucose homeostasis during pregnancy.

AB Sex of birds is genetically determined through inheritance of the ZW sex chromosomes (ZZ males and ZW females). Although the mechanisms of avian sex determination remains unknown, the genetic sex is experimentally reversible by in ovo exposure to exogenous estrogens (ZZ-male feminization) or aromatase inhibitors (ZW-female masculinization). Expression of various testis-and ovary-specific marker genes during the normal and reversed gonadal sex differentiation in chicken embryos has been extensively studied, but the roles of sex-specific epigenetic marks in sex differentiation are unknown. In this study, we show that a 170-nt region in the promoter of CYP19A1/aromatase, a key gene required for ovarian estrogen biosynthesis and feminization of chicken embryonic gonads, contains highly quantitative, nucleotide base-level epigenetic marks that reflect phenotypic gonadal sex differentiation. We developed a protocol to feminize ZZ-male chicken embryonic gonads in a highly quantitative manner by direct injection of emulsified ethynylestradiol into yolk at various developmental stages. Taking advantage of this experimental sex reversal model, we show that the epigenetic sex marks in the CYP19A1/aromatase promoter involving DNA methylation and histone lysine methylation are feminized significantly but only partially in sex-converted gonads even when morphological and transcriptional marks of sex differentiation show complete feminization, being indistinguishable from gonads of normal ZW females. Our study suggests that the epigenetic sex of chicken embryonic gonads is more stable than the morphologically or transcriptionally characterized sex differentiation, suggesting the importance of the nucleotide base-level epigenetic sex in gonadal sex differentiation.

AB Objective: To estimate the risks for psychopathology and functional impairments in adulthood among a longitudinal sample of youth with and without attention-deficit/hyperactivity disorder (ADHD) diagnosed in childhood.
Method: This was a case-controlled, 16-year (15-19 years) prospective follow-up study of ADHD. 140 boys with and 120 without DSM-III-R ADHD were recruited from pediatric and psychiatric settings. The main outcome measures were structured diagnostic interviews and measures of psychosocial, educational, and neuropsychological functioning. Data were collected from 1988 to 2006.
Results: At the 16-year follow-up, subjects with ADHD continued to significantly differ from controls in lifetime rates of antisocial, mood, anxiety, and addictive disorders, but with the exception of a higher interval prevalence of anxiety disorders (20% vs 8%; z = 2.32, P = .02) and smoking dependence (27% vs 11%; z = 2.30, P = .02), the incidence of individual disorders in the 6-year interval between the current and prior follow-up did not differ significantly from controls. At follow-up, the ADHD subjects compared with controls were significantly (P < .05) more impaired in psychosocial, educational, and neuropsychological functioning, differences that could not be accounted for by other active psychopathology.
Conclusions: These long-term prospective findings provide further evidence for the high morbidity associated with ADHD across the life cycle, stressing the importance of early recognition of this disorder for prevention and early intervention strategies. These findings also indicate that, in adulthood, ADHD confers significant risks for impairment that cannot be accounted for by other psychopathology.

AB Objective: To compare sociodemographic and clinical features, acute and continuation treatment outcomes, and adverse events/side effect burden between outpatients with chronic (current episode > 2 years) versus nonchronic major depressive disorder (MDD) who were treated with combination antidepressant therapy or selective serotonin reuptake inhibitor (SSRI) monotherapy.
Method: 663 outpatients with chronic (n = 368) or nonchronic (n = 295) moderate to severe DSM-IV-TR MDD (17-item Hamilton Depression Rating Scale score >= 16) were enrolled from March 2008 through September 2009 in a single-blind 7-month prospective randomized trial conducted at 6 primary and 9 psychiatric care sites across the United States. Participants were treated with escitalopram monotherapy plus placebo or 1 of 2 combination treatments (bupropion sustained-release [SR] + escitalopram or venlafaxine extended-release [XR] + mirtazapine). Analyses compared baseline sociodemographic and clinical characteristics, rates of remission (at least 1 of the last 2 consecutive scores on the 16-item Quick Inventory of Depressive Symptomatology Self-Report [QIDS-SR16] < 6, with the other < 8), and adverse events/side effect burden (Frequency, Intensity, and Burden of Side Effects Ratings) obtained at 12 and 28 weeks.
Results: Participants with chronic MDD were at greater socioeconomic disadvantage and had greater medical and psychiatric disease burden. The chronic and nonchronic groups did not differ in rates of remission at 12 weeks (35.9% vs 42.0%, respectively; odds ratio [OR] = 0.778, P = .1500; adjusted OR [AGR] = 0.956, P = .8130) or at 28 weeks (41.0% vs 49.8%, respectively; OR = 0.706, P = .0416; AOR = 0.837, P = .3448). Participants with chronic MDD had higher final QIDS-SR16 scores and smaller overall percent changes in QIDS-SR16 from baseline to exit, but these differences did not remain after adjusting for covariates. There were no significant differences in adverse events or side effect burden. No significant interactions were found between chronicity and type of treatment at 12 or 28 weeks.
Conclusion: Chronicity of illness does not appear to differentially impact acute or longer-term outcomes with SSRI monotherapy or combination antidepressant medication treatment in patients with moderate to severe nonpsychotic MDD.

TI Gender Differences in Never-Medicated First-Episode Schizophrenia and

DT Article
ID 1ST EPISODE PSYCHOSIS; SEX-DIFFERENCES; CHINESE SCHIZOPHRENIA; VERBAL

AB Background: Schizophrenia shows gender differences in patients' clinical presentation, neurocognitive impairment, course, and treatment outcome. The aims of this study were to compare gender differences in clinical features and cognitive functioning in first-episode and chronic schizophrenia among Han Chinese inpatients.
Method: We compared gender differences in 262 unmedicated first-episode schizophrenia and 960 chronic schizophrenia inpatients (diagnosed according to DSM-IV) to 804 matched healthy controls on sociodemographic characteristics, smoking behavior, and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Patients were also rated on the Positive and Negative Syndrome Scale. The study was conducted from December 2006 to May 2008.
Results: Schizophrenia first occurred in both first-episode and chronic schizophrenia patients at a significantly earlier age in male than female patients (P < .05 and P < .001, respectively). The paranoid subtype of schizophrenia was more common in female patients only in chronic schizophrenia, not first-episode patients. Further, cigarette smoking was more common in male than female patients from both patient groups, and, among men, more chronic schizophrenia patients than controls smoked, while among women, fewer chronic schizophrenia patients than controls smoked. Female chronic schizophrenia patients had more severe positive and general psychopathological symptoms, whereas male patients had more severe negative symptoms. By contrast, first-episode schizophrenia patients showed no gender differences in symptoms and severity. Both first-episode and chronic schizophrenia patients performed worse than controls on most of the cognitive tasks. RBANS attention, delayed memory, and immediate memory were less impaired in female than male chronic schizophrenia patients, and first-episode schizophrenia patients showed no gender differences.
Conclusions: Chronic schizophrenia patients have notable gender differences in the age at onset, smoking, symptom severity, and cognitive function favoring women, but first-episode schizophrenia patients show few gender differences.

AB Objective. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) has been reported as a paraneoplastic syndrome in many different types of malignancies. Several case reports of SIADH have been reported in patients with olfactory neuroblastoma (ONB), but the exact incidence is unknown. The purpose of this study was to review our experience with olfactory neuroblastoma and to identify all patients who had a history of SIADH prior to the diagnosis of ONB.
Study Design. Case series and chart review
Setting. Tertiary care university-affiliated medical center.
Subjects and Methods. A total of 21 patients presented to our institution with ONB between 1997 and 2009. All records were reviewed for a history of preoperative hyponatremia or SIADH.
Results. Three patients were identified who had a history of SIADH prior to the diagnosis of ONB. Immunohistochemical staining of the tumor specimens from the 3 patients with SIADH was positive for arginine vasopressin. SIADH resolved in all 3 patients after successful treatment of ONB.
Conclusion. Although uncommon, SIADH can be the presenting symptom of ONB and should be considered during the workup for idiopathic SIADH.

AB Objective: The commission of wartime atrocities is a phenomenon known to occur among military personnel deployed to war zones. Although some research has examined the psychological sequelae to these events, there is virtually no research on the causes or correlates of such behavior. The present study examined associations among personality variables, combat exposure, and witnessing or participating in wartime atrocities during the Vietnam War. Method: One thousand one hundred and four Army and Marine veterans of the Vietnam War completed self-report measures that assessed personality, combat exposure, and participation in atrocities. Structural equation modeling was used to test a model in which combat exposure mediated the association between personality and participation in atrocities. Results: Combat exposure was strongly associated with self-reported participation in atrocities and fully mediated the association between trait aggression and participation in atrocities. Combat exposure was also shown to partially mediate the association between trait neuroticism and atrocities but evidenced no relationship with trait disconstraint. Disconstraint showed only a direct association with participation in atrocities. Conclusions: Personality and exposure to heavy combat should be considered not only risk factors for physical or mental illness, but also important risk factors for the commission of atrocities. Longitudinal research on risk factors for the commission of atrocities is needed, with a focus on those service members tasked with more dangerous assignments. Military commanders may wish to pay close attention to units under greater combat stress and to continue to devote resources to screening and treatment of members of these units.

AB Background: Opioid abuse has continued to increase at an alarming rate since the 1990s. As documented by different medical specialties, medical boards, advocacy groups, and the Drug Enforcement Administration, available evidence suggests a wide variance in chronic opioid therapy of 90 days or longer in chronic non-cancer pain. Part 1 describes evidence assessment.
Objectives: The objectives of opioid guidelines as issued by the American Society of Interventional Pain Physicians (ASIPP) are to provide guidance for the use of opioids for the treatment of chronic non-cancer pain, to produce consistency in the application of an opioid philosophy among the many diverse groups involved, to improve the treatment of chronic non-cancer pain, and to reduce the incidence of abuse and drug diversion. The focus of these guidelines is to curtail the abuse of opioids without jeopardizing non-cancer pain management with opioids.
Results:
1) There is good evidence that non-medical use of opioids is extensive; one-third of chronic pain patients may not use prescribed opioids as prescribed or may abuse them, and illicit drug use is significantly higher in these patients.
2) There is good evidence that opioid prescriptions are increasing rapidly, as the majority of prescriptions are from non-pain physicians, many patients are on long-acting opioids, and many patients are provided with combinations of long-acting and short-acting opioids.
3) There is good evidence that the increased supply of opioids, use of high dose opioids, doctor shoppers, and patients with multiple comorbid factors contribute to the majority of the fatalities.
4) There is fair evidence that long-acting opioids and a combination of long-acting and short-acting opioids contribute to increasing fatalities and that even low-doses of 40 mg or 50 mg of daily morphine equivalent doses may be responsible for emergency room admissions with overdoses and deaths.
5) There is good evidence that approximately 60% of fatalities originate from opioids prescribed within the guidelines, with approximately 40% of fatalities occurring in 10% of drug abusers.
6) The short-term effectiveness of opioids is fair, whereas the long-term effectiveness of opioids is limited due to a lack of long-term (>3 months) high quality studies, with fair evidence with no significant difference between long-acting and short-acting opioids.
7) Among the individual drugs, most opioids have fair evidence for short-term and limited evidence for long-term due to a lack of quality studies.
8) The evidence for the effectiveness and safety of chronic opioid therapy in the elderly for chronic non-cancer pain is fair for short-term and limited for long-term due to lack of high quality studies; limited in children and adolescents and patients with comorbid psychological disorders due to lack of quality studies; and the evidence is poor in pregnant women.
9) There is limited evidence for reliability and accuracy of screening tests for opioid abuse due to lack of high quality studies.
10) There is fair evidence to support the identification of patients who are non-compliant or abusing prescription drugs or illicit drugs through urine drug testing and prescription drug monitoring programs, both of which can reduce prescription drug abuse or doctor shopping.
Disclaimer: The guidelines are based on the best available evidence and do not constitute inflexible treatment recommendations. Due to the changing body of evidence, this document is not intended to be a "standard of care."

AB Results:
Part 2 of the guidelines on responsible opioid prescribing provides the following recommendations for initiating and maintaining chronic opioid therapy of 90 days or longer.
1. A) Comprehensive assessment and documentation is recommended before initiating opioid therapy, including documentation of comprehensive history, general medical condition, psychosocial history, psychiatric status, and substance use history. (Evidence: good)
B) Despite limited evidence for reliability and accuracy, screening for opioid use is recommended, as it will identify opioid abusers and reduce opioid abuse. (Evidence: limited)
C) Prescription monitoring programs must be implemented, as they provide data on patterns of prescription usage, reduce prescription drug abuse or doctor shopping. (Evidence: good to fair)
D) Urine drug testing (UDT) must be implemented from initiation along with subsequent adherence monitoring to decrease prescription drug abuse or illicit drug use when patients are in chronic pain management therapy. (Evidence: good)
2. A) Establish appropriate physical diagnosis and psychological diagnosis if available prior to initiating opioid therapy. (Evidence: good)
B) Caution must be exercised in ordering various imaging and other evaluations, interpretation and communication with the patient; to avoid increased fear, activity restriction, requests for increased opioids, and maladaptive behaviors. (Evidence: good)
C) Stratify patients into one of the 3 risk categories - low, medium, or high risk.
D) A pain management consultation, may assist non-pain physicians, if high-dose opioid therapy is utilized. (Evidence: fair)
3. Essential to establish medical necessity prior to initiation or maintenance of opioid therapy. (Evidence: good)
4. Establish treatment goals of opioid therapy with regard to pain relief and improvement in function. (Evidence: good)
5. A) Long-acting opioids in high doses are recommended only in specific circumstances with severe intractable pain that is not amenable to short-acting or moderate doses of long-acting opioids, as there is no significant difference between long-acting and short-acting opioids for their effectiveness or adverse effects. (Evidence: fair)
B) The relative and absolute contraindications to opioid use in chronic non-cancer pain must be evaluated including respiratory instability, acute psychiatric instability, uncontrolled suicide risk, active or history of alcohol or substance abuse, confirmed allergy to opioid agents, coadministration of drugs capable of inducing life-limiting drug interaction, concomitant use of benzodiazepines, active diversion of controlled substances, and concomitant use of heavy doses of central nervous system depressants. (Evidence: fair to limited)
6. A robust agreement which is followed by all parties is essential in initiating and maintaining opioid therapy as such agreements reduce overuse, misuse, abuse, and diversion. (Evidence: fair)
7. A) Once medical necessity is established, opioid therapy may be initiated with low doses and short-acting drugs with appropriate monitoring to provide effective relief and avoid side effects. (Evidence: fair for short-term effectiveness, limited for long-term effectiveness)
B) Up to 40 mg of morphine equivalent is considered as low dose, 41 to 90 mg of morphine equivalent as a moderate dose, and greater than 91 mg of morphine equivalence as high dose. (Evidence: fair)
C) In reference to long-acting opioids, titration must be carried out with caution and overdose and misuse must be avoided. (Evidence: good)
8. A) Methadone is recommended for use in late stages after failure of other opioid therapy and only by clinicians with specific training in the risks and uses. (Evidence: limited)
B) Monitoring recommendation for methadone prescription is that an electrocardiogram should be obtained prior to initiation, at 30 days and yearly thereafter. (Evidence: fair)
9. In order to reduce prescription drug abuse and doctor shopping, adherence monitoring by UDT and PMDPs provide evidence that is essential to the identification of those patients who are non-compliant or abusing prescription drugs or illicit drugs. (Evidence: fair)
10. Constipation must be closely monitored and a bowel regimen be initiated as soon as deemed necessary. (Evidence: good)
11. Chronic opioid therapy may be continued, with continuous adherence monitoring, in well-selected populations, in conjunction with or after failure of other modalities of treatments with improvement in physical and functional status and minimal adverse effects. (Evidence: fair)
Disclaimer: The guidelines are based on the best available evidence and do not constitute inflexible treatment recommendations. Due to the changing body of evidence, this document is not intended to be a "standard of care."

AB Background-Patients with acute coronary syndrome (ACS) have a higher incidence of recurrent ischemic events. The aim of this study was to compare the plaque characteristics of nonculprit lesions between ACS and non-ACS patients using optical coherence tomography (OCT) imaging.
Methods and Results-Patients who had 3-vessel OCT imaging were selected from the Massachusetts General Hospital (MGH) OCT Registry. MGH registry is a multicenter registry of patients undergoing OCT. The prevalence and characteristics of nonculprit plaques were compared between ACS and non-ACS patients. A total of 248 nonculprit plaques were found in 104 patients: 45 plaques in 17 ACS patients and 203 plaques in 87 non-ACS patients. Compared with plaques of non-ACS patients, plaques of ACS patients had a wider lipid arc (147.3 +/- 29.5 degrees versus 116.2 +/- 33.7, P< 0.001), a longer lipid length (10.7 +/- 5.9 mm versus 7.0 +/- 3.7 mm, P= 0.002), a larger lipid volume index [ averaged lipid arcxlipid length] (1605.5 +/- 1013.1 versus 853.4 +/- 570.8, P< 0.001), and a thinner fibrous cap (70.2 +/- 20.2 mu m versus 103.3 +/- 46.8 mu m, P< 0.001). Moreover, thin-cap fibroatheroma (64.7% versus 14.9%, P< 0.001), macrophage (82.4% versus 37.9%, P= 0.001), and thrombus (29.4% versus 1.1%, P< 0.001) were more frequent in ACS patients. Although the prevalence of microchannel did not differ between the groups, the closest distance from the lumen to microchannel was shorter in ACS subjects than in non-ACS (104.6 +/- 67.0 mu m versus 198.3 +/- 133.0 mu m, P= 0.027).
Conclusions-Nonculprit lesions in patients with ACS have more vulnerable plaque characteristics compared with those with non-ACS. Neovascularization was more frequently located close to the lumen in patients with ACS. (Circ Cardiovasc Imaging. 2012; 5: 433-440.)

AB Background-Medication nonadherence rates are high. The factors predicting nonadherence in heart failure remain unclear.
Methods and Results-A sample of 202 adults with heart failure was enrolled from the northeastern United States and followed for 6 months. Specific aims were to describe the types of objectively measured medication adherence (eg, taking, timing, dosing, drug holidays) and to identify contributors to nonadherence 6 months after enrollment. Latent growth mixture modeling was used to identify distinct trajectories of adherence. Indicators of the 5 World Health Organization dimensions of adherence (socioeconomic, condition, therapy, patient, and healthcare system) were tested to identify contributors to nonadherence. Two distinct trajectories were identified and labeled persistent adherence (77.8%) and steep decline (22.3%). Three contributors to the steep decline in adherence were identified. Participants with lapses in attention (adjusted OR, 2.65; P=0.023), those with excessive daytime sleepiness (OR, 2.51; P=0.037), and those with >= 2 medication dosings per day (OR, 2.59; P=0.016) were more likely to have a steep decline in adherence over time than to have persistent adherence.
Conclusions-Two distinct patterns of adherence were identified. Three potentially modifiable contributors to nonadherence have been identified. (Circ Heart Fail. 2012; 5: 430-436.)

AB This study examines whether individuals with borderline personality disorder (BPD) would exhibit augmented emotional responses to picture stimuli after being challenged with an ideographic interpersonal conflict script. Participants were 24 adults diagnosed with BPD, 23 adults diagnosed with obsessive-compulsive personality disorder (OCPD), and 28 normal controls. Participants viewed emotionally evocative pictures before and after listening to the interpersonal script while a variety of physiological measures were recorded. Findings indicated that the interpersonal script was effective in eliciting enduring emotional responses from the BPD group relative to the control groups. However, despite the effectiveness of the interpersonal challenge task, there were no group differences in emotional responding to the affect eliciting stimuli. The findings underscore the complexities involved in examining emotional dysregulation in BPD in a laboratory setting.

AB Diabetes mellitus type II (or type 2 diabetes; DM2) has multiple definitions but is generally considered to be a disease marked by insulin resistance and loss of beta cell function that develops in adulthood. Today, greater than 90% of patients with diabetes have DM2. When uncontrolled, DM2 may result in comorbidities such as cardiovascular disease, retinopathy, neuropathy, immune system dysfunction, and renal failure. Classically, treatment of type 2 diabetes has included dietary and lifestyle changes. Even with behavior modification and oral hypoglycemics, many patients are unable to maintain glycemic control. With a growing understanding of the hormonal signals involved in the pathogenesis of type 2 diabetes, there has been a shift in the therapeutic approach to this growing epidemic. Bariatric surgery has been shown to decrease the progression and potentially reverse the effects of diabetes in 80% to 90% of patients. In addition, bariatric operations are associated with sustained weight loss in contrast to nonsurgical options.
The antidiabetic effect of batiatric operations is likely due to the improvement in the hormonal dysregulation associated with the development of diabetes. Many patients with diabetes, however, have irreparably damaged insulin production capabilities as well. In addition, it is well recognized that transplantation may be required for patients with severe loss of islet cell function. Surgery for type 2 diabetes, via bariatric procedures and transplantation, has become an important treatment modality for patients with advanced disease. (C) 2012 Elsevier Inc. All rights reserved.

AB Purpose This study tested the null hypothesis that there is no difference between expected improvement and actual improvement of symptoms with carpal tunnel release (CTR). Secondary analyses addressed factors associated with both expected relief and actual relief of symptoms with carpal tunnel syndrome surgical release, predictors of arm-specific disability, and satisfaction with surgery.
Methods Sixty-six employed, English-speaking adult patients requesting limited-incision open CTR for electrodiagnostically confirmed carpal tunnel syndrome completed questionnaires before and after surgery. Before surgery, patients completed a survey regarding demographic data, expected improvement of symptoms with surgery, expected return to work after surgery, and validated questionnaires assessing arm-specific disability, job burnout, depressive symptoms, catastrophic thinking, and pain anxiety. An average of 6 +/- 5 months (range, 40 d to 19 mo) after surgery, participants completed questionnaires regarding actual improvement of symptoms with surgery, actual return to work, satisfaction with surgery, and arm-specific disability.
Results Patients' actual and expected improvements with CTR were similar, with the exception of sleep disturbance, which was an average 0.3 points better than patients expected on a 5-point Likert scale. Lower postoperative disability was associated with men, less catastrophic thinking, and greater actual improvement of weakness with CTR. Fifty-three percent of the variation in satisfaction with treatment was associated with single status, more education, and relief of pain, sleep disturbance, and tingling.
Conclusions Actual relief of symptoms with CTR matched patients' expectations in an employed population. Satisfaction with treatment correlated with relief of symptoms. (J Hand Surg 2012;37A:1324-1329. Copyright (c) 2012 by the American Society for Surgery of the Hand. All rights reserved.)

AB Purpose To identify factors associated with arthroscopically diagnosed scaphoid fracture displacement and instability.
Methods This was a secondary use of data from 2 prospective cohort studies. The studies included 58 consecutive adult patients with a scaphoid fracture who elected arthroscopy-assisted operative fracture treatment: some for displacement, some as part of a prospective protocol, and others to avoid a cast. All patients had preoperative computed tomography with reconstructions in planes defined by the long axis of the scaphoid.
Results Arthroscopy revealed 38 unstable fractures (movement between fracture fragments; 66%), 27 of which were also displaced. All arthroscopically determined displaced fractures were unstable, and 11 of the 31 arthroscopically determined, nondisplaced fractures were unstable. There was a significant correlation between radiographic comminution (more than 2 fracture fragments) and arthroscopically determined displacement and instability.
Conclusions Radiographic comminution is associated with displacement and instability as determined by arthroscopy. (J Hand Surg 2012;37A:1405-1410. Copyright (c) 2012 by the American Society for Surgery of the Hand. All rights reserved.)

AB Purpose There is no consensus as to the best treatment of Mason type II fractures without concomitant elbow fractures or dislocation. The aim of this systematic review was to compare the results of operative and nonoperative treatment of these injuries.
Methods We systematically screened the databases of PubMed, EMBASE, and Cochrane Library until September 2011 for studies on nonoperative or operative treatment of Mason type II fractures. We defined successful treatment as an excellent or good result according to the Broberg and Morrey score, Mayo Elbow Performance Score, or Radin score. Exclusion criteria were duration of follow-up of less than 6 months, an improperly described therapy or combination of therapies, skeletal immaturity, and articles written in languages other than English.
Results Among 717 studies, 9 retrospective case series (level IV) describing 224 patients satisfied our inclusion criteria. Nonoperative treatment was successful in 114 of 142 patients (80%) pooled from the studies (42% to 96% success in individual studies). Open reduction and internal fixation was successful in 76 of 82 patients (93%) (81% to 100% success in individual studies).
Conclusions Only a few studies with a low level of evidence address the treatment of isolated, displaced, partial articular fractures. There is a need for sufficiently powered randomized, controlled trials.

TI Risk Factors for Posttraumatic Heterotopic Ossification of the Elbow:
Case-Control Study
SO JOURNAL OF HAND SURGERY-AMERICAN VOLUME
LA English
DT Article
DE Elbow fracture; heterotopic ossification
ID FLOATING ELBOW; BONE; OUTCOMES; INJURY
AB Purpose Heterotopic ossification (HO) is well-known after surgical repair of elbow fractures, but little is known about risk factors for its development in these patients. The purpose of this study was to define factors associated with development of HO.
Methods We used a prospective fracture registry collected in 2 Level I trauma centers and medical chart review to examine all elbow fractures treated surgically between 2002 and 2009. We determined which of these patients developed HO with an impact on range of motion (Hastings class II and III). We conducted a matched case-control study to examine factors associated with risk of HO. We used conditional logistic regression to compare occurrences of risk factors between cases and controls, matched by fracture type, age, and sex.
Results Our database contained 786 elbow fractures treated surgically. Of these, 55 developed clinically relevant HO. The risk of HO varied among types of elbow fractures, with combined olecranon and radial head fractures having no HO and floating elbows (fractures on both sides of the elbow joint) having the highest incidence of HO at 36%. In multiple conditional logistic regression, risk factors for the development of HO were days to surgery, with subjects waiting 8 or more days having 12 times the odds of HO than subjects having surgery within a day of injury, and time to postoperative mobilization, with subjects who had at least 15 days to mobilization having greater odds of HO than those who had less than 7 days to mobilization.
Conclusions Heterotopic ossification of the elbow occurs frequently after surgical repair of elbow fractures, with an incidence of 7% in this registry. In the case-control sample, conditions associated with development of HO included longer time to surgery and longer time to mobilization after surgery. (J Hand Surg 2012;37A:1422-1429.

TI NURSES' DETECTION OF INEFFECTIVE INSPIRATORY EFFORTS DURING MECHANICAL
VENTILATION
SO AMERICAN JOURNAL OF CRITICAL CARE
LA English
DT Article
ID ASYNCHRONY
AB Background Patient-ventilator dyssynchrony is common and may influence patients' outcomes. Detection of such dyssynchronies relies on careful observation of patients and airway flow and pressure measurements. Given the shortage of specialists, critical care nurses could be trained to identify dyssynchronies.
Objective To evaluate the accuracy of specifically trained critical care nurses in detecting ineffective inspiratory efforts during expiration.
Methods We compared 2 nurses' evaluations of measurements from 1007 breaths in 8 patients with the evaluations of experienced critical care physicians. Sensitivity, specificity, positive predictive value, negative predictive value, and the Cohen kappa for interobserver agreement were calculated.
Results For the first nurse, sensitivity was 92.5%, specificity was 98.3%, positive predictive value was 95.4%, negative predictive value was 97.1%, and kappa was 0.92 (95% CI, 0.89-0.94). For the second nurse, sensitivity was 98.5%, specificity was 84.7%, positive predictive value was 70.7%, negative predictive value was 99.3%, and kappa was 0.74 (95% CI, 0.70-0.78).
Conclusion Specifically trained nurses can reliably detect ineffective inspiratory efforts during expiration. (American Journal of Critical Care. 2012;21:e89-e93)

TI Congenital Diaphragmatic Defects: Proposal for a New Classification

AB Congenital diaphragmatic defects (CDDs) are a common group of birth defects, yet we presently know little about their pathogenesis. No systematic study documenting the detailed morphology of CDD has been performed, and current classification schemata of diaphragm phenotypes incompletely capture the location and extent of diaphragmatic involvement. To define the range of CDD anatomy, diaphragmatic pathology was reviewed from an examination of 181 autopsy records of children with CDDs at Children's Hospital Boston between 1927 and 2006. Defects were classified according to several parameters, including type (communicating versus noncommunicating) and location (anterior, posterior, etc.). The information permitted development of a phenotyping worksheet for prospective use on patients undergoing diaphragmatic repair at Children's Hospital Boston or MassGeneral Hospital for Children. Fifty-three patients who died between 1990 and 2006 had a total of 63 defects. Thirty-nine had a "classic'' CDD phenotype (64% posterolateral, 18% hemidiaphragmatic aplasia, and 18% anterior). The remaining 19 defects, not fitting classical descriptions, were located in the posteromedial, anterolateral, or lateral regions of the diaphragm. Prospective data collected during surgical repair revealed posterolateral defects in 34 of 41 cases that demonstrated wide phenotypic variability in size, location, shape, type, and extent of organ displacement. Congenital diaphragmatic defects display significant phenotypic variation. Because rigorous anatomic evaluation and documentation are important steps towards elucidating the developmental biology of these disorders, we suggest establishment of a new and more precise classification using the model presented herein.

AB Pneumonia is a common cause of morbidity and mortality and the most frequent source of sepsis. Bacteria that try to invade normally sterile body sites are recognized by innate immune cells through pattern recognition receptors, among which toll-like receptors (TLRs) feature prominently. Interleukin-1 receptor (IL-1R)-associated kinase (IRAK)-M is a proximal inhibitor of TLR signaling expressed by epithelial cells and macrophages in the lung. To determine the role of IRAK-M in host defense against bacterial pneumonia, IRAK-M-deficient (IRAK-M-/-) and normal wild-type (WT) mice were infected intranasally with Klebsiella pneumoniae. IRAK-M mRNA was upregulated in lungs of WT mice with Klebsiella pneumonia, and the absence of IRAK-M resulted in a strongly improved host defense as reflected by reduced bacterial growth in the lungs, diminished dissemination to distant body sites, less peripheral tissue injury and better survival rates. Although IRAK-M-/- alveolar macrophages displayed enhanced responsiveness toward intact K. pneumoniae and Klebsiella lipopolysaccharide (LPS) in vitro, IRAK-M-/- mice did not show increased cytokine or chemokine levels in their lungs after infection in vivo. The extent of lung inflammation was increased in IRAK-M-/- mice shortly after K. pneumoniae infection, as determined by semiquantitative scoring of specific components of the inflammatory response in lung tissue slides. These data indicate that IRAK-M impairs host defense during pneumonia caused by a common gram-negative respiratory pathogen. Online address: http://www.molmed.org doi: 10.2119/molmed.2011.00450

AB For more than a half century, autoimmunity has been linked to a diverse array of heart diseases, including rheumatic carditis, myocarditis, Chagas' cardiomyopathy, post-myocardial infarction (Dressler's) syndrome, and idiopathic dilated cardiomyopathy. Why the heart is targeted by autoimmunity in these seemingly unrelated conditions has remained enigmatic. Here, we discuss our recent studies indicating that this susceptibility is mediated by impaired negative selection of autoreactive a-myosin heavy-chain-specific CD4(+) T cells in the thymus of both mice and humans. We describe how this process may place the heart at increased risk for autoimmune attack following ischemic or infectious injury, providing a rationale for the development of antigen-specific tolerogenic therapies.

AB Robo2 is the cell surface receptor for the repulsive guidance cue Slit and is involved in axon guidance and neuronal migration. Nephrin is a podocyte slit-diaphragm protein that functions in the kidney glomerular filtration barrier. Here, we report that Robo2 is expressed at the basal surface of mouse podocytes and colocalizes with nephrin. Biochemical studies indicate that Robo2 forms a complex with nephrin in the kidney through adaptor protein Nck. In contrast to the role of nephrin that promotes actin polymerization, Slit2-Robo2 signaling inhibits nephrin-induced actin polymerization. In addition, the amount of F-actin associated with nephrin is increased in Robo2 knockout mice that develop an altered podocyte foot process structure. Genetic interaction study further reveals that loss of Robo2 alleviates the abnormal podocyte structural phenotype in nephrin null mice. These results suggest that Robo2 signaling acts as a negative regulator on nephrin to influence podocyte foot process architecture.

TI Dose quantification of topical drug delivery to the paranasal sinuses by
fluorescein luminosity calculation

ID IRRIGATION; SURGERY; SPRAY
AB Background: Our group has previously described a novel method of objectively quantifying the temporospatial distribution of sinonasal irrigation in a nonanesthetized patient. The purpose of this study is to refine this technique to provide an accurate method of determining concentration of dose delivery as well.
Methods: An endoscope at a fixed position within 2 dissected cadaveric heads was used to image 4 subsites under blue light. Each site was dosed with 3 mL of successively increasing concentrations of fluorescein-labeled saline. In vitro images of the labeled saline were also captured over a range of depths. Images were exported into a graphics editing program that was used to calculate luminosity at 3 regions per subsite. The relationship between luminosity and fluorescein concentration was calculated using a Pearson product-moment correlation coefficient. Significance was determined using a 2-tailed Student t test.
Results: Luminosity of the irrigation delivered to the maxillary sinus, lamina papyracea, ethmoid roof, and frontal sinus positively correlated with fluorescein concentration over a range of 0.1 to 0.01 mg/mL (n = 6; r = 0.95, p < 0.001; r = 0.94, p < 0.001; r = 0.92, p < 0.001; and r= 0.94, p < 0.001; respectively). There was no significant difference between luminosities of a 0.01 mg/mL irrigation layer subtending a range of depths up to 6.6 mm.
Conclusion: The described method is capable of determining the concentration of fluorescein delivery to a mucosal surface via objective luminosity quantification. Our data suggest that this method will remain accurate regardless of the potential for heterogeneous pooling of irrigation. This method may be used to optimize delivery strategies of a variety of topical sinonasal therapies. (C) 2012 ARS-AAOA, LLC.

AB Background: Self-monitoring is a key behavior change mechanism associated with sustained health behavior change. Although Web-based interventions can offer user-friendly approaches for self-monitoring, engagement with these tools is suboptimal. Increased use could encourage, promote, and sustain behavior change.
Objective: To determine whether email prompts or email plus telephone prompts increase self-monitoring of behaviors on a website created for a multiple cancer risk reduction program.
Methods: We recruited and enrolled participants (N = 100) in a Web-based intervention during a primary care well visit at an urban primary care health center. The frequency of daily self-monitoring was tracked on the study website. Participants who tracked at least one behavior 3 or more times during week 1 were classified as meeting the tracking threshold and were assigned to the observation-only group (OO, n = 14). This group was followed but did not receive prompts. Participants who did not meet the threshold during week 1 were randomly assigned to one of 2 prompting conditions: automated assistance (AA, n = 36) or automated assistance + calls (AAC, n = 50). During prompting periods (weeks 2-3), participants in the AA and AAC conditions received daily automated emails that encouraged tracking and two tailored self-monitoring reports (end of week 2, end of week 3) that provided feedback on tracking frequency. Individuals in the AAC condition also received two technical assistance calls from trained study staff. Frequency of self-monitoring was tracked from week 2 through week 17.
Results: Self-monitoring rates increased in both intervention conditions during prompting and declined when prompting ceased. Over the 16 weeks of observation, there was a significant between-group difference in the percentage who met the self-monitoring threshold each week, with better maintenance in the AAC than in the AA condition (P < .001). Self-monitoring rates were greater in the OO group than in either the AA or AAC condition (P < .001).
Conclusions: Prompting can increase self-monitoring rates. The decrease in self-monitoring after the promoting period suggests that additional reminder prompts would be useful. The use of technical assistance calls appeared to have a greater effect in promoting self-monitoring at a therapeutic threshold than email reminders and the tailored self-monitoring reports alone.

ID ADDITIONAL PRIMARY CANCERS; HIGH-RISK INDIVIDUALS; UPDATED EXPERIENCE;

AB Background/Objectives: The purpose of this study is to compare surgically resected intraductal papillary mucinous neoplasms (IPMNs) in patients with and without a family history of pancreatic cancer to gain insight into differences that may suggest the need for differential management.
Methods: A retrospective review of patients who underwent resection of an IPMN at the Massachusetts General Hospital (1990-2011) was conducted. Three hundred and twenty-four patients of whom 45 (13.9%) had a family history of pancreatic cancer were identified. Patients with (PFH) and without (NFH) a family history of pancreatic cancer were compared.
Results: There were no differences in demographic characteristics between groups. Extra-pancreatic malignancies diagnosed prior to the IPMN were more common in those with a PFH (35.6% vs 20.1%, p = 0.03). There were no differences in IPMN characteristics between groups including no difference in the presence of invasive disease (p = 0.55). Concurrent pancreatic ductal adenocarcinomas were more common in those with a PFH (11.1% vs 2.9%, p = 0.02). The survival in the PFH group was marginally lower than the NFH group, a difference found to be attributable to the higher prevalence of extra-pancreatic malignancies.
Conclusion: Characteristics of surgically resected IPMNs are not different between patients with and without a family history of pancreatic cancer. Most importantly, the incidence of invasive disease is not different, suggesting that these lesions may not be more aggressive when they occur in the presence of a family history of pancreatic cancer.

AB Memantine, a partial antagonist of N-methyl-D-aspartate receptor (NMDAR), approved for moderate to severe Alzheimer's disease (AD) treatment within the US and Europe under brand name Namenda (Forest), Axura and Akatinol (Merz), and Ebixa and Abixa (Lundbeck), may have potential in alleviating additional neurological conditions, such as vascular dementia (VD) and Parkinson's disease (PD). In various animal models, memantine has been reported to be a neuroprotective agent that positively impacts both neurodegenerative and vascular processes. While excessive levels of glutamate result in neurotoxicity, in part through the over-activation of NMDARs, memantine-as a partial NMDAR antagonist, blocks the NMDA glutamate receptors to normalize the glutamatergic system and ameliorate cognitive and memory deficits. The key to memantine's therapeutic action lies in its uncompetitive binding to the NMDAR through which low affinity and rapid off-rate kinetics of memantine at the level of the NMDAR-channel preserves the physiological function of the receptor, underpinning memantine's tolerability and low adverse event profile. As the biochemical pathways evoked by NMDAR antagonism also play a role in PD and since no other drug is sufficiently effective to substitute for the first-line treatment of L-dopa despite its side effects, memantine may be useful in PD treatment with possibly fewer side effects. In spite of the relative modest nature of its adverse effects, memantine has been shown to provide only a moderate decrease in clinical deterioration in AD and VD, and hence efforts are being undertaken in the design of new and more potent memantine-based drugs to hopefully provide greater efficacy.

AB Recent work exploring the use of high-molecular weight alcohols to treat essential tremor (ET) has identified octanoic acid as a potential novel tremor-suppressing agent. We used an established harmaline-based mouse model of ET to compare tremor suppression by 1-octanol and octanoic acid. The dose-related effect on digitized motion power within the tremor bandwidth as a fraction of overall motion power was analyzed. Both 1-octanol and octanoic acid provided significant reductions in harmaline tremor. An 8-carbon alkyl alcohol and carboxylic acid each suppress tremor in a pre-clinical mouse model of ET. Further studies are warranted to determine the safety and efficacy of such agents in humans with ET.

AB Ca2+-mediated remodeling of the actin cytoskeleton is a dynamic process that regulates cell motility through the modulation of rho guanosine triphosphatase (GTPase) signaling. Kidney podocytes are unique, pericyte-like cells with a complex cellular organization consisting of a cell body, major processes, and foot processes (FPs). The FPs form a characteristic interdigitating pattern with FPs of neighboring podocytes, leaving in between filtration slits that are covered by the slit diaphragm (SD). The actin-based FP and the SD form the final barrier to proteinuria. Mutations affecting several podocyte proteins cause disruption of the filtration barrier and rearrangement of the highly dynamic podocyte actin cytoskeleton. Proteins regulating the plasticity of the podocyte actin cytoskeleton are therefore of critical importance for sustained kidney barrier function. Dynamic regulation of the actin-based contractile apparatus in podocyte FPs is essential for sustained kidney filter function. Thus, the podocyte represents an excellent model system to study calcium signaling and actin dynamics in a physiologic context. Here, we discuss the regulation of podocyte actin dynamics by angiotensin or bradykinin-mediated calcium influx and downstream Rho GTPase signaling pathways and how these pathways are operative in other cells including fibroblasts and cancer cells.

There are screening guidelines for depression in cardiac patients, but the feasibility and cost-effectiveness of screening all cardiac patients is controversial. This process may be improved if a subset of cardiac patients at high risk for depression could be identified using information readily available to clinicians and screened.
Objective: To identify risk factors for a positive depression screen at the time of admission in hospitalized cardiac patients.
Methods: A total of 561 consecutively screened cardiac inpatients underwent the Patient Health Questionnaire-2 (PHQ-2). A prospective chart review was performed to assess potential risk factors for depression that would be readily available to front-line clinicians. Rates of risk factors were compared between patients with positive and negative PHQ-2 depression screens, and multivariate logistic regression was performed to assess whether specific risk factors were independently associated with positive screens.
Results: Of the 561 patients screened, 13.5% (n = 76) had a positive depression screen (PHQ-2 >= 2). In the univariate analyses, several variables were associated with a positive depression screen. On multivariate analysis, an elevated white blood cell (WBC) count (>10 x 10(9) cells per liter) and prescription of an antidepressant on admission were independently associated with a positive depression screen, while current smoking showed a trend toward significance.
Conclusion: Information on these three identified risk factors (WBC count, antidepressant use, and smoking) is readily available to clinicians, and patients with these diagnoses may represent a cohort who would benefit from targeted depression screening in certain settings.

AB Pulmonary damage caused by chronic colonization of the cystic fibrosis (CF) lung by microbial communities is the proximal cause of respiratory failure. While there has been an effort to document the microbiome of the CF lung in pediatric and adult patients, little is known regarding the developing microflora in infants. We examined the respiratory and intestinal microbiota development in infants with CF from birth to 21 months. Distinct genera dominated in the gut compared to those in the respiratory tract, yet some bacteria overlapped, demonstrating a core microbiota dominated by Veillonella and Streptococcus. Bacterial diversity increased significantly over time, with evidence of more rapidly acquired diversity in the respiratory tract. There was a high degree of concordance between the bacteria that were increasing or decreasing over time in both compartments; in particular, a significant proportion (14/16 genera) increasing in the gut were also increasing in the respiratory tract. For 7 genera, gut colonization presages their appearance in the respiratory tract. Clustering analysis of respiratory samples indicated profiles of bacteria associated with breast-feeding, and for gut samples, introduction of solid foods even after adjustment for the time at which the sample was collected. Furthermore, changes in diet also result in altered respiratory microflora, suggesting a link between nutrition and development of microbial communities in the respiratory tract. Our findings suggest that nutritional factors and gut colonization patterns are determinants of the microbial development of respiratory tract microbiota in infants with CF and present opportunities for early intervention in CF with altered dietary or probiotic strategies.

AB Objective: Large genome-wide association studies (GWASs) have identified many novel genes influencing Alzheimer disease (AD) risk, but most of the genetic variance remains unexplained. We conducted a 2-stage GWAS for AD-related quantitative measures of hippocampal volume (HV), total cerebral volume (TCV), and white matter hyperintensities (WMH).
Methods: Brain magnetic resonance imaging measures of HV, TCV, and WMH were obtained from 981 Caucasian and 419 African American AD cases and their cognitively normal siblings in the MIRAGE (Multi Institutional Research in Alzheimer's Genetic Epidemiology) Study, and from 168 AD cases, 336 individuals with mild cognitive impairment, and 188 controls in the Alzheimer's Disease Neuroimaging Initiative Study. A GWAS for each trait was conducted in the 2 Caucasian data sets in stage 1.
Results from the 2 data sets were combined by meta-analysis. In stage 2, 1 single nucleotide polymorphism (SNP) from each region that was nominally significant in each data set (p < 0.05) and strongly associated in both data sets (p < 1.0 x 10(-5)) was evaluated in the African American data set. Results: Twenty-two markers (14 for HV, 3 for TCV, and 5 for WMH) from distinct regions met criteria for evaluation in stage 2. Novel genome-wide significant associations (p < 5.0 x 10(-8)) were attained for HV with SNPs in the APOE, F5/SELP, LHFP, and GCFC2 gene regions. All of these associations were supported by evidence in each data set. Associations with different SNPs in the same gene (p < 1 x 10(-5) in Caucasians and p < 2.2 x 10(-4) in African Americans) were also observed for PICALM with HV, SYNPR with TCV, and TTC27 with WMH.
Interpretation: Our study demonstrates the efficacy of endophenotypes for broadening our understanding of the genetic basis of AD. ANN NEUROL 2012;72:65-75

AB Objective: In addition to its role in hemorrhagic stroke, advanced cerebral amyloid angiopathy (CAA) is also associated with ischemic lesions and vascular cognitive impairment. We used functional magnetic resonance imaging (MRI) techniques to identify CAA-associated vascular dysfunction.
Methods: Functional MRI was performed on 25 nondemented subjects with probable CAA (mean +/- standard deviation age, 70.2 +/- 7.8 years) and 12 healthy elderly controls (age, 75.3 +/- 6.2 years). Parameters measured were reactivity to visual stimulation (quantified as blood oxygen level-dependent [BOLD] response amplitude, time to peak response, and time to return to baseline after stimulus cessation) and resting absolute cerebral blood flow in the visually activated region (measured by arterial spin labeling).
Results: CAA subjects demonstrated reduced response amplitude (percentage change in BOLD signal, 0.65 +/- 0.28 vs 0.89 +/- 0.14; p < 0.01), prolonged time to peak (11.1 +/- 5.1 vs 6.4 +/- 1.8 seconds; p < 0.001), and prolonged time to baseline (16.5 +/- 6.7 vs 11.6 +/- 3.1 seconds; p < 0.001) relative to controls. These differences were independent of age, sex, and hypertension in multivariable analysis and were also present in secondary analyses excluding nonresponsive voxels or voxels containing chronic blood products. Within the CAA group, longer time to peak correlated with overall volume of white matter T2 hyperintensity (Pearson correlation, 0.53; p = 0.007). Absolute resting blood flow in visual cortex, in contrast, was essentially identical between the groups (44.0 +/- 12.6 vs 45.0 +/- 10.0ml/100g/min, p = 0.8).
Interpretation: Functional MRI identifies robust differences in both amplitude and timing of the response to visual stimulation in advanced CAA. These findings point to potentially powerful approaches for identifying the mechanistic links between vascular amyloid deposits, vascular dysfunction, and CAA-related brain injury.

AB Background-In anticipation of applying Appropriate Use Criteria for percutaneous coronary intervention (PCI) quality improvement, we determined the prevalence of appropriate, uncertain, and inappropriate PCIs stratified by indication for all PCIs performed in the state of Washington.
Methods and Results-Within the Clinical Outcomes Assessment Program, we assigned appropriateness ratings to all PCIs performed in 2010 in accordance with published Appropriate Use Criteria. Of 13 291 PCIs, we successfully mapped the clinical scenario to the Appropriate Use Criteria in 9924 (75%) cases. Of the 3367 PCIs not classified, common failures to map to the criteria included nonacute PCI without prior noninvasive stress results (n = 1906; 57%) and unstable angina without high-risk features (n = 902; 27%). Of mapped PCIs, 8010 (71%) were for acute indications, with 7887 (98%) rated as appropriate, 39 (<1%) as uncertain, and 84 (1%) as inappropriate. Of 1914 mapped nonacute indications, 847 (44%) were rated as appropriate, 748 (39%) as uncertain, and 319 (17%) as inappropriate. Assuming results for noninvasive stress tests when data were missing, in the best-case scenario, 319 (8%) of nonacute PCIs were classified as inappropriate compared with 1459 (38%) in the worst-case scenario. Variation in inappropriate PCIs by facility was greatest for mapped nonacute indications (median = 14%; 25th to 75th percentiles = 9% to 24%) and nonacute indications with missing data precluding appropriateness classification (median = 54%; 25th to 75th percentiles = 35% to 66%).
Conclusions-In a complete cohort of PCIs performed in Washington state, 1% of PCIs for acute indications and 17% of PCIs for nonacute indications were classified as inappropriate. Missing data on noninvasive stress tests present a challenge in the application of the criteria for quality improvement. (Circ Cardiovasc Qual Outcomes. 2012; 5: 445-453.)

TI Does the Inclusion of Stroke Severity in a 30-Day Mortality Model Change
Standardized Mortality Rates at Veterans Affairs Hospitals?

AB Background-The Centers for Medicare and Medicaid Services is considering developing a 30-day ischemic stroke hospital-level mortality model using administrative data. We examined whether inclusion of the National Institutes of Health Stroke Scale (NIHSS), a measure of stroke severity not included in administrative data, would alter 30-day mortality rates in the Veterans Health Administration.
Methods and Results-A total of 2562 veterans admitted with ischemic stroke to 64 Veterans Health Administration Hospitals in the fiscal year 2007 were included. First, we examined the distribution of unadjusted mortality rates across the Veterans Health Administration. Second, we estimated 30-day all-cause, risk standardized mortality rates (RSMRs) for each hospital by adjusting for age, sex, and comorbid conditions using hierarchical models with and without the inclusion of the NIHSS. Finally, we examined whether adjustment for the NIHSS significantly changed RSMRs for each hospital compared with other hospitals. The median unadjusted mortality rate was 3.6%. The RSMR interquartile range without the NIHSS ranged from 5.1% to 5.6%. Adjustment with the NIHSS did not change the RSMR interquartile range (5.1%-5.6%). Among veterans >= 65 years, the RSMR interquartile range without the NIHSS ranged from 9.2% to 10.3%. With adjustment for the NIHSS, the RSMR interquartile range changed from 9.4% to 10.0%. The plot of 30-day RSMRs estimated with and without the inclusion of the NIHSS in the model demonstrated overlapping 95% confidence intervals across all hospitals, with no hospital significantly below or above the mean-unadjusted 30-day mortality rate. The 30-day mortality measure did not discriminate well among hospitals.
Conclusion-The impact of the NIHSS on RSMRs was limited. The small number of stroke admissions and the narrow range of 30-day stroke mortality rates at the facility level in the Veterans Health Administration cast doubt on the value of using 30-day RSMRs as a means of identifying outlier hospitals based on their stroke care quality.

AB Background-The benefits of intravenous tissue-plasminogen activator (tPA) in acute ischemic stroke are time-dependent. Emergency medical services (EMS) hospital prenotification of an incoming patient with potential stroke may provide a means of reducing evaluation and treatment times and improving treatment rates; yet, available data are limited.
Methods and Results-We examined 371 988 patients with acute ischemic stroke transported by EMS and enrolled in Get With The Guidelines-Stroke from April 1, 2003, to March 31, 2011. Prenotification occurred in 249 197 (67.0%) of EMS-transported patients. Among eligible patients arriving by 2 hours, patients with EMS prenotification were more likely to be treated with tPA within 3 hours (82.8% versus 79.2%, absolute difference +3.5%, P<0.0001, the National Institutes of Health Stroke Scale-documented cohort; 73.0% versus 64.0%, absolute difference +9.0%, P<0.0001, overall cohort). Patients with EMS prenotification had shorter door-to-imaging times (26 minutes versus 31 minutes, P<0.0001), shorter door-to-needle times (78 minutes versus 80 minutes, P<0.0001), and shorter symptom onset-to-needle times (141 minutes versus 145 minutes, P<0.0001). In multivariable and modified Poisson regression analyses accounting for the clustering of patients within hospitals, use of EMS prenotification was independently associated with greater likelihood of door-to-imaging times <= 25 minutes, door-to-needle times for tPA <= 60 minutes, onset-to-needle times <= 120 minutes, and tPA use within 3 hours.
Conclusions-EMS hospital prenotification is associated with improved evaluation, timelier stroke treatment, and more eligible patients treated with tPA. These results support the need for initiatives targeted at increasing EMS prenotification rates as a mechanism from improving quality of care and outcomes in stroke.

TI Clopidogrel Use and Hospital Quality in Medically Managed Patients With

AB Background-Clopidogrel prescription is a class I guideline recommendation for medically managed patients with non-ST-segment-elevation myocardial infarction (NSTEMI). However, clopidogrel has historically been underused in this population. We evaluated contemporary rates of its use and evaluated associated factors, with a particular focus on hospital quality of myocardial infarction (MI) care.
Methods and Results-We examined clopidogrel prescription rates among 23 186 patients with NSTEMI discharged from 382 US hospitals between October 2009 and March 2011. Associations between clopidogrel prescription and various patient and hospital factors, including hospital quality of MI care, were determined with regression modeling. Of the sample, 54.9% of eligible patients with NSTEMI received clopidogrel prescription at hospital discharge. Variation in rate by hospital was large, ranging from 22% to 97%. A variety of patient and hospital factors were associated with clopidogrel prescription. Hospital quality of MI care demonstrated modest association with clopidogrel prescription (odds ratio, 0.68; 95% CI, 0.54-0.85) between the lowest and highest hospital quality quartile) and accounted for 5.7% of the variation in prescription rates.
Conclusions-Clopidogrel prescription is significantly underused in the medically managed NSTEMI population and demonstrates wide variability by hospital. Although hospital quality of MI care is associated with its use, the findings suggest that it only has a modest effect. Therefore, efforts to improve clopidogrel use likely will require measures beyond improving the overall hospital quality of MI care. (Circ Cardiovasc Qual Outcomes. 2012; 5: 523-531.)

AB Background-The impact of polyvascular disease (peripheral arterial disease [PAD] and cerebrovascular disease [CVD]) on long-term cardiovascular outcomes among older patients with acute myocardial infarction has not been well studied.
Methods and Results-Patients with non-ST-segment-elevation myocardial infarction aged >= 65 years from the CRUSADE (Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the ACC/AHA Guidelines) registry who survived to hospital discharge were linked to longitudinal data from the Centers for Medicare & Medicaid Services (n=34 205). All patients were presumed to have coronary artery disease (CAD) and were classified into the following 4 groups: 10.7% with prior CVD (CAD+CVD group); 11.5% with prior PAD (CAD+PAD); 3.1% with prior PAD and CVD (CAD+PAD+CVD); and 74.7% with no polyvascular disease (CAD alone). Cox proportional hazards modeling was used to examine the hazard of long-term mortality and composite of death or readmission for myocardial infarction or stroke (median follow-up, 35 months; interquartile range, 17-49 months). Compared with the CAD alone group, patients with polyvascular disease had greater comorbidities, were less likely to undergo revascularization, and received less often recommended discharge interventions. Three-year mortality rates increased with number of arterial bed involvement as follows: 33% for CAD alone, 49% for CAD+PAD, 52% for CAD+CVD, and 59% for CAD+PAD+CVD. Relative to the CAD alone group, patients with all 3 arterial beds involved had the highest risk of long-term mortality (adjusted hazard ratio [95% CI], 1.49 [1.38-1.61]; CAD+CVD, 1.38 [1.31-1.44]; CAD+PAD, 1.29 [1.23-1.35]). Similarly, the risk of long-term composite ischemic events was highest among patients in the CAD+PAD+CVD group.
Conclusions-Among older patients with non-ST-segment-elevation myocardial infarction, those with polyvascular disease have substantially higher long-term risk for recurrent events or death. Future studies targeting greater adherence to secondary prevention strategies and novel therapies are needed to help to reduce long-term cardiovascular events in this vulnerable population.

AB Background-Adherence to cardioprotective medications in the year after acute coronary syndrome hospitalization is generally poor and is associated with increased risk of rehospitalization and mortality. Few interventions have specifically targeted this high-risk patient population to improve medication adherence. We hypothesize that a multifaceted patient-centered intervention could improve adherence to cardioprotective medications.
Methods and Results-To evaluate this intervention, we propose enrolling 280 patients with a recent acute coronary syndrome event into a multicenter randomized, controlled trial. The intervention comprises4 main components: (1) pharmacist-led medication reconciliation and tailoring; (2) patient education; (3) collaborative care between pharmacist and primary care provider/cardiologist; and (4) 2 types of voice messaging (educational and medication refill reminder calls). Patients in the intervention arm will visit with the study pharmacist approximate to 1 week post-hospital discharge. The pharmacist will work with the patient and collaborate with providers to reconcile medication issues. Voice messages will augment the educational process and remind patients to refill their cardioprotective medications. The study will compare the intervention versus usual care for 12 months. The primary outcome of interest is adherence using the ReComp method. Secondary and tertiary outcomes include achievement of targets for blood pressure and low-density lipoprotein, and reduction in the combined cardiovascular end points of myocardial infarction hospitalization, coronary revascularization, and all-cause mortality. Finally, we will also evaluate the cost-effectiveness of the intervention compared with usual care.
Conclusions-If the intervention is effective in improving medication adherence and demonstrating a lower cost, the intervention has the potential to improve cardiovascular outcomes in this high-risk patient population. (Circ Cardiovasc Qual Outcomes. 2012; 5: 571-576.)

AB PURPOSE. To employ functional manganese-enhanced MRI (MEMRI) to image layer-specific changes in calcium-dependent activities in the rat retina during light versus dark adaptation.
METHODS. Functional MEMRI at 203203700 mu m was used to study light and dark adaptation in the same animals (N = 10) in which one eye was covered and the fellow eye was not. The activity encoding of the light and dark adaptation was achieved in awake conditions and imaged under anesthesia. T-1-weighted MRI at 11.7 tesla (T) was performed using two identical radiofrequency transceiver coils to allow interleaved MRI acquisitions of the two eyes. An intravascular contrast agent was also used to verify layer assignments.
RESULTS. MEMRI detected contrasts among the inner retina, outer retina, and choroid. Independent confirmation of the vascular layers and boundaries between layers was documented with an intravascular contrast agent. The retinal layer thicknesses agreed with published data. The outer retina had lower MEMRI activity in light compared with dark adaption (P < 0.001), consistent with the increased metabolic demand associated with the "dark current." The inner retina had higher MEMRI activity in light compared with dark adaption (P < 0.05). The choroid MEMRI activity was not statistically different between light and dark adaptation (P > 0.05).
CONCLUSIONS. This study demonstrated a high-resolution MEMRI protocol to image functional activities among different layers of the retinas in awake animals during light and dark adaptation. This approach could have potential applications in animal models of retinal dysfunction. (Invest Ophthalmol Vis Sci. 2012;53:4352-4358) DOI:10.1167/iovs.11-8826

AB PURPOSE. The goal of this project was to identify markers of abnormal neovascularization of the retinal vasculature, which is quintessential of pathologic angiogenesis that occurs in blinding diseases such as proliferative diabetic retinopathy.
METHODS. Abnormal retinal neovascularization was induced in rat pups by subjecting them to the 50/10 oxygen-induced retinopathy (OIR) protocol, which involves fluctuating levels of ambient oxygen. A peptide library (that was displayed on phage) was positively and negatively screened over the surface of retinas isolated from experimental and control rats, respectively. Binding of phage to retinal vessels was evaluated by confocal microscopy of retinal flat mounts decorated with fluorescently labeled phage. The topography of the inner limiting membrane was studied by scanning electron microscopy.
RESULTS. Screening a library of peptides displayed on phage over the surface of OIR retinas resulted in isolation of a particular phage (SH phage) that distinguished between abnormal neovessels and the normal vasculature. As expected, the recognition of abnormal neovessels relied on the unique peptide insert of SH phage. Abnormal neovessels consisted of at least three cell types that were present in the following order of descending abundance: endothelial > pericytes > macrophage/microglia. SH phage recognized both endothelial cells and macrophage/microglia. Finally, SH phage decorated abnormal neovessels at an early stage of their genesis.
CONCLUSIONS. Abnormal development of neovessels is associated with early expression of distinct epitopes on the surface of cells within the pathologic vasculature. Screening phage display libraries is one approach to detecting such changes, and the resulting phage are potential imaging tools and/or drug delivery vehicles.

AB PURPOSE. To investigate the effects of central corneal thickness (CCT)-associated variants on primary open-angle glaucoma (POAG) risk using single nucleotide polymorphisms (SNP) data from the Glaucoma Genes and Environment (GLAUGEN) and National Eye Institute (NEI) Glaucoma Human Genetics Collaboration (NEIGHBOR) consortia.
METHODS. A replication analysis of previously reported CCT SNPs was performed in a CCT dataset (n = 1117) and these SNPs were then tested for association with POAG using a larger POAG dataset (n=6470). Then a CCT genome-wide association study (GWAS) was performed. Top SNPs from this analysis were selected and tested for association with POAG. cDNA libraries from fetal and adult brain and ocular tissue samples were generated and used for candidate gene expression analysis.
RESULTS. Association with one of 20 previously published CCT SNPs was replicated: rs12447690, near the ZNF469 gene (P = 0.001; beta = -5.08 mu m/allele). None of these SNPs were significantly associated with POAG. In the CCT GWAS, no SNPs reached genome-wide significance. After testing 50 candidate SNPs for association with POAG, one SNP was identified, rs7481514 within the neurotrimin (NTM) gene, that was significantly associated with POAG in a low-tension subset (P = 0.00099; Odds Ratio [OR] = 1.28). Additionally, SNPs in the CNTNAP4 gene showed suggestive association with POAG (top SNP = rs1428758; P = 0.018; OR = 0.84). NTM and CNTNAP4 were shown to be expressed in ocular tissues.
CONCLUSIONS. The results suggest previously reported CCT loci are not significantly associated with POAG susceptibility. By performing a quantitative analysis of CCT and a subsequent analysis of POAG, SNPs in two cell adhesion molecules, NTM and CNTNAP4, were identified and may increase POAG susceptibility in a subset of cases.

AB Objectives: Noninvasive brain stimulation (NIBS) interventions have demonstrated promising results in the clinical treatment of pain, according to several preliminary trials, although the results have been mixed. The limitations of clinical research on NIBS are the insufficient understanding of its mechanisms of action, a lack of adequate safety data, and several disparities with regard to stimulation parameters, which have hindered the generalizability of such studies. Thus, experimental animal research that allows the use of more invasive interventions and creates additional control of independent variables and confounders is desirable. To this end, we systematically reviewed animal studies investigating the analgesic effects of NIBS. In addition, we also explored the investigation of NIBS in animal models of stroke as to compare these findings with NIBS animal pain research. Methods: Of 1916 articles that were found initially, we identified 15 studies (stroke and pain studies) per our eligibility criteria that used NIBS methods, such as transcranial direct current stimulation, paired associative stimulation, transcranial magnetic stimulation, and transcranial electrostimulation. We extracted the main outcomes on stroke and pain, as well as the methods and electrical parameters of each technique. Results: NIBS techniques are effective in alleviating pain. Similar beneficial clinical effects are observed in stroke. The main insights from these animal studies are the following: 1) combination of NIBS with analgesic drugs has a synergistic effect; 2) effects are dependent on the parameters of stimulation, and in fact, not necessarily the strongest stimulation parameter (i.e., the largest intensity of stimulation) is associated with the largest benefit; 3) pain studies show an overall good quality as indexed by Animals in Research: Reporting In Vivo Experiments guidelines of the reporting of animal experiments, but insufficient with regard to the reporting of safety data for brain stimulation; 4) these studies suggest that NIBS techniques have a primary effect on synaptic plasticity, but they also suggest other mechanisms of action such as via neurovascular modulation. Conclusions: We found a limited number of animal studies for both pain and stroke NIBS experimental research. There is a lack of safety data in animal studies in these two topics and results from these studies have not been yet fully tested and translated to human research. We discuss the challenges and limitations of translating experimental animal research on NIBS into clinical studies.

AB Objectives: Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that delivers low-intensity currents facilitating or inhibiting spontaneous neuronal activity. tDCS is attractive since dose is readily adjustable by simply changing electrode number, position, size, shape, and current. In the recent past, computational models have been developed with increased precision with the goal to help customize tDCS dose. The aim of this review is to discuss the incorporation of high-resolution patient-specific computer modeling to guide and optimize tDCS. Methods: In this review, we discuss the following topics: 1) The clinical motivation and rationale for models of transcranial stimulation is considered pivotal in order to leverage the flexibility of neuromodulation; 2) the protocols and the workflow for developing high-resolution models; 3) the technical challenges and limitations of interpreting modeling predictions; and 4) real cases merging modeling and clinical data illustrating the impact of computational models on the rational design of rehabilitative electrotherapy. Conclusions: Though modeling for noninvasive brain stimulation is still in its development phase, it is predicted that with increased validation, dissemination, simplification, and democratization of modeling tools, computational forward models of neuromodulation will become useful tools to guide the optimization of clinical electrotherapy.

AB Objective: To review the use of noninvasive brain stimulation (NBS) as a therapeutic tool to enhance neuroplasticity following traumatic brain injury (TBI). Materials and Methods: Based on a literature search, we describe the pathophysiological events following TBI and the rationale for the use of transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) in this setting. Results: The pathophysiological mechanisms occurring after TBI vary across time and therefore require differential interventions. Theoretically, given the neurophysiological effects of both TMS and tDCS, these tools may: 1) decrease cortical hyperexcitability acutely after TBI; 2) modulate long-term synaptic plasticity as to avoid maladaptive consequences; and 3) combined with physical and behavioral therapy, facilitate cortical reorganization and consolidation of learning in specific neural networks. All of these interventions may help decrease the burden of disabling sequelae after brain injury. Conclusions: Evidence from animal and human studies reveals the potential benefit of NBS in decreasing the extent of injury and enhancing plastic changes to facilitate learning and recovery of function in lesioned neural tissue. However, this evidence is mainly theoretical at this point. Given safety constraints, studies in TBI patients are necessary to address the role of NBS in this condition as well as to further elucidate its therapeutic effects and define optimal stimulation parameters.

AB Objectives: We have previously reported that transcranial direct current stimulation (tDCS) delivered to the occipital cortex enhances visual functional recovery when combined with three months of computer-based rehabilitative training in patients with hemianopia. The principal objective of this study was to evaluate the temporal sequence of effects of tDCS on visual recovery as they appear over the course of training and across different indicators of visual function. Methods: Primary objective outcome measures were 1) shifts in visual field border and 2) stimulus detection accuracy within the affected hemifield. These were compared between patients randomized to either vision restoration therapy (VRT) combined with active tDCS or VRT paired with sham tDCS. Training comprised two half-hour sessions, three times a week for three months. Primary outcome measures were collected at baseline (pretest), monthly interim intervals, and at posttest (three months). As secondary outcome measures, contrast sensitivity and reading performance were collected at pretest and posttest time points only. Results: Active tDCS combined with VRT accelerated the recovery of stimulus detection as between-group differences appeared within the first month of training. In contrast, a shift in the visual field border was only evident at posttest (after three months of training). tDCS did not affect contrast sensitivity or reading performance. Conclusions: These results suggest that tDCS may differentially affect the magnitude and sequence of visual recovery in a manner that is task specific to the type of visual rehabilitative training strategy employed.

AB Background: We have previously established the reliability and cross-sectional validity of the SIST-M (Structured Interview and Scoring Tool-Massachusetts Alzheimer's Disease Research Center), a shortened version of an instrument shown to predict progression to Alzheimer disease (AD), even among persons with very mild cognitive impairment (vMCI).
Objective: To test the predictive validity of the SIST-M.
Methods: Participants were 342 community-dwelling, nondemented older adults in a longitudinal study. Baseline Clinical Dementia Rating (CDR) ratings were determined by either (1) clinician interviews or (2) a previously developed computer algorithm based on 60 questions (of a possible 131) extracted from clinician interviews. We developed age + sex + education-adjusted Cox proportional hazards models using CDR-sum-of-boxes (CDR-SB) as the predictor, where CDR-SB was determined by either a clinician interview or an algorithm; models were run for the full sample (n = 342) and among those jointly classified as vMCI using clinician-based and algorithm-based CDR ratings (n = 156). We directly compared predictive accuracy using time-dependent receiver operating characteristic (ROC) curves.
Results: AD hazard ratios (HRs) were similar for clinician-based and algorithm-based CDR-SB: for a 1-point increment in CDR-SB, the respective HRs [95% confidence interval (CI)] were 3.1 (2.5, 3.9) and 2.8 (2.2, 3.5); among those with vMCI, the respective HRs (95% CI) were 2.2 (1.6, 3.2) and 2.1 (1.5, 3.0). Similarly high predictive accuracy was achieved: the concordance probability (weighted average of the area-under-the-ROC curves) over follow-up was 0.78 versus 0.76 using clinician-based versus algorithm-based CDR-SB.
Conclusion: CDR scores based on items from this shortened interview had high predictive ability for AD-comparable to that using a lengthy clinical interview.

AB Energy supply is the most prominent function of mitochondria, but in addition, mitochondria are indispensable for a multitude of other important cellular functions including calcium (Ca2+) signaling and buffering, the supply of metabolites and the sequestration of apoptotic factors. The efficiency of those functions highly depends on the proper positioning of mitochondria within the cytosol. In lymphocytes, mitochondria preferentially localize into the vicinity (similar to 200 nm) of the immune synapse (IS). This localization is regulated by motor-based cytoskeleton-mediated transport, the fusion/fission dynamics of mitochondria, and probably also through tethering with the ER. IS formation also induces the accumulation of CRAC/ORAI1 Ca2+ channels, the CRAC/ORAI channel activator STIM1, K+ channels and plasma membrane Ca2+ ATPase (PMCA) within the IS. Such a large agglomeration of Ca2+ binding organelles and proteins highlights the IS as a critical cellular compartment for Ca2+ dependent lymphocyte activation. At the IS, Ca2+ microdomains generated beneath open CRAC/ORAI channels provide a rapid, robust and reliable mechanism for driving cellular responses in mast cells and T cells. Here, we discuss the relevance of motor-based mitochondrial transport, fusion, fission and tethering for mitochondrial localization in T cells and the importance of subplasmalemmal mitochondria to control local CRAC/ORAI1-dependent Ca2+ microdomains at the IS for efficient T lymphocyte activation.

AB Bacterial infections causing acute exacerbations of chronic obstructive pulmonary disease (AECOPD) frequently require antibacterial treatment. More evidence is needed to guide antibiotic choice.
The Moxifloxacin in Acute Exacerbations of Chronic Bronchitis TriaL (MAESTRAL) was a multiregional, randomised, double-blind non-inferiority outpatient study. Patients were aged >= 60 yrs, with an Anthonisen type I exacerbation, a forced expiratory volume in 1 s <60% predicted and two or more exacerbations in the last year. Following stratification by steroid use patients received moxifloxacin 400 mg p.o.q.d. (5 days) or amoxicillin/clavulanic acid 875/125 mg p.o. b.i.d. (7 days). The primary end-point was clinical failure 8 weeks post-therapy in the per protocol population.
Moxifloxacin was noninferior to amoxicillin/clavulanic acid at the primary end-point (111 (20.6%) out of 538, versus 114 (22.0%) out of 518, respectively; 95% CI -5.89-3.83%). In patients with confirmed bacterial AECOPD, moxifloxacin led to significantly lower clinical failure rates than amoxicillin/clavulanic acid (in the intent-to-treat with pathogens, 62 (19.0%) out of 327 versus 85 (25.4%) out of 335, respectively; p=0.016). Confirmed bacterial eradication at end of therapy was associated with higher clinical cure rates at 8 weeks post-therapy overall (p=0.0014) and for moxifloxacin (p=0.003). Patients treated with oral corticosteroids had more severe disease and higher failure rates.
The MAESTRAL study showed that moxifloxacin was as effective as amoxicillin/clavulanic acid in the treatment of outpatients with AECOPD. Both therapies were well tolerated.

MECHANISMS; TOXICITY
AB Excessive free iron in blood and in organ tissues (so called iron overload) has been observed in degenerative diseases such as atherosclerosis, cancer, neurological, and certain autoimmune diseases, in which fibrin-like deposits are also found. Although most of the body iron is bound to hemoglobin and myoglobin in a divalent ferrous form, a certain amount of iron exists in blood as a trivalent (ferric) ion. This particular chemical state of iron has been shown to be toxic to the human body when not controlled by endogenous and/or dietary chelating agents. Experiments described in this paper show for the first time that ferric ions (Fe3+) can generate hydroxyl radicals without participation of any redox agent, thus making it a special case of the Fenton reaction. Ferric chloride was also demonstrated to induce aggregation of purified fibrinogen at the same molar concentrations that were used for the generation of hydroxyl radicals. Iron-aggregated fibrinogen, by contrast to native molecule, could not be dissociated into polypeptide subunit chains as shown in a polyacrylamide gel electrophoresis. The mechanism of this phenomenon is very likely based on hydroxyl radical-induced modification of fibrinogen tertiary structure with the formation of insoluble aggregates resistant to enzymatic and chemical degradations. Soluble modified fibrinogen species can be determined in blood of thrombotic patients by the reaction with protamine sulfate and/or by scanning electron microscopy. In view of these findings, it is postulated that iron-induced alterations in fibrinogen structure is involved in pathogenesis of certain degenerative diseases associated with iron overload and persistent thrombosis. It is concluded that the detection of hydroxyl radical-modified fibrinogen may be utilized as a marker of a thrombotic condition in human subjects.

AB Airway stenosis in pregnancy is challenging and the literature does not offer consensus regarding its evaluation and anesthetic management. A 21-year-old nulliparous woman with ectodermal dysplasia and severe glottic stenosis was referred to the obstetric anesthesia team for evaluation and peripartum management recommendations. She had a history of a congenital complete glottic web that required a tracheostomy at birth. After decannulation at age four, she was lost to follow-up. On examination in early pregnancy, she was found to have a dangerously narrow airway with fixed vocal cords and a glottic aperture of 2-3 mm. At nine weeks of gestation an elective tracheostomy was performed under local anesthesia. She later underwent an uneventful cesarean delivery under spinal anesthesia. Ultimately, early interdisciplinary planning for an elective tracheostomy helped assure patient safety during advancing pregnancy and delivery. (C) 2012 Elsevier Ltd. All rights reserved.

AB Three-dimensional (3-D) visualization of the fine structures within the lung parenchyma could advance our understanding of alveolar physiology and pathophysiology. Current knowledge has been primarily based on histology, but it is a destructive two-dimensional (2-D) technique that is limited by tissue processing artifacts. Micro-CT provides high-resolution three-dimensional (3-D) imaging within a limited sample size, but is not applicable to intact lungs from larger animals or humans. Optical reflectance techniques offer the promise to visualize alveolar regions of the large animal or human lung with sub-cellular resolution in three dimensions. Here, we present the capabilities of three optical reflectance techniques, namely optical frequency domain imaging, spectrally encoded confocal microscopy, and full field optical coherence microscopy, to visualize both gross architecture as well as cellular detail in fixed, phosphate buffered saline-immersed rat lung tissue. Images from all techniques were correlated to each other and then to corresponding histology. Spatial and temporal resolution, imaging depth, and suitability for in vivo probe development were compared to highlight the merits and limitations of each technology for studying respiratory physiology at the alveolar level.

AB Quantitative analysis of optical coherence tomography data can be strongly hampered by speckle. Here, we introduce a new method to reduce speckle, which leverages from Fourier-domain configurations and operates on individual axial scans. By subdividing the digitized spectrum into a number of distinct narrower windows, each with a different center frequency, several independent speckle patterns result. These can be averaged to yield a lower-resolution image with strongly reduced speckle. The full resolution image remains available for human interpretation; the low resolution version can be used for parametric imaging or quantitative analysis. We demonstrate this technique using intravascular optical frequency domain imaging data acquired in vivo. (C) 2012 Society of Photo-Optical Instrumentation Engineers (SPIE).

AB This study focuses on the impact a spinal cord injury may have on achieving physical and emotional intimacy, and potential to maximize sexual ability and quality of life. Spinal cord injury is a traumatic, life-altering event that is usually associated with loss of motor and sensory function, as well as sexual impairment. At the time of injury, the individual is faced with devastating loss and an abundance of new information in a setting of extreme stress and challenge. In the acute rehabilitation setting, there is often a considerable void in providing education and resources regarding sexual concerns and needs. There is a positive relationship between sexual education and sexual activity. The impact of inadequate sexual counseling and education as a part of rehabilitation can be deleterious.

AB The use of combination drug regimens has dramatically improved the clinical outcome for patients with multiple myeloma. However, to date, combination treatments have been limited to approved drugs and a small number of emerging agents. Using a systematic approach to identify synergistic drug combinations, combination high-throughput screening (cHTS) technology, adenosine A2A and beta-2 adrenergic receptor (beta 2AR) agonists were shown to be highly synergistic, selective, and novel agents that enhance glucocorticoid activity in B-cell malignancies. Unexpectedly, A2A and beta 2AR agonists also synergize with melphalan, lenalidomide, bortezomib, and doxorubicin. An analysis of agonists, in combination with dexamethasone or melphalan in 83 cell lines, reveals substantial activity in multiple myeloma and diffuse large B-cell lymphoma cell lines. Combination effects are also observed with dexamethasone as well as bortezomib, using multiple myeloma patient samples and mouse multiple myeloma xenograft assays. Our results provide compelling evidence in support of development of A2A and beta 2AR agonists for use in multi-drug combination therapy for multiple myeloma. Furthermore, use of cHTS for the discovery and evaluation of new targets and combination therapies has the potential to improve cancer treatment paradigms and patient outcomes.

Up to 9-day survival and control of thrombocytopenia following GalT-KO swine liver xenotransplantation in baboons. Xenotransplantation 2012; 19: 256264.. (c) 2012 John Wiley & Sons A/S. Abstract: Background: With standard miniature swine donors, survivals of only 3 days have been achieved in primate liver-transplant recipients. The recent production of alpha1,3-galactosyl transferase knockout (GalT-KO) miniature swine has made it possible to evaluate xenotransplantation of pig organs in clinically relevant pig-to-non-human primate models in the absence of the effects of natural anti-Gal antibodies. We are reporting our results using GalT-KO liver grafts. Methods: We performed GalT-KO liver transplants in baboons using an immunosuppressive regimen previously used by our group in xeno heart and kidney transplantation. Post-operative liver function was assessed by laboratory function tests, coagulation parameters and histology. Results: In two hepatectomized recipients of GalT-KO grafts, post-transplant liver function returned rapidly to normal. Over the first few days, the synthetic products of the donor swine graft appeared to replace those of the baboon. The first recipient survived for 6 days and showed no histopathological evidence of rejection at the time of death from uncontrolled bleeding, probably caused by transfusion-refractory thrombocytopenia. Amicar treatment of the second and third recipients led to maintenance of platelet counts of over 40 000 per mu l throughout their 9- and 8-day survivals, which represents the longest reported survival of pig-to-primate liver transplants to date. Both of the last two animals nevertheless succumbed to bleeding and enterococcal infection, without evidence of rejection. Conclusions: These observations suggest that thrombocytopenia after liver xenotransplantation may be overcome by Amicar therapy. The coagulopathy and sepsis that nevertheless occurred suggest that additional causes of coagulation disturbance must be addressed, along with better prevention of infection, to achieve long-term survival.

AB Bipolar disorder (BD) is a chronic, debilitating disorder with recurrent manic and depressive episodes. More than 75% of bipolar patients have a current or lifetime diagnosis of a comorbid anxiety disorder. Comorbid anxiety in BD is associated with greater illness severity, greater functional impairment, and poorer illness-related outcomes. Effectively treating comorbid anxiety in individuals with BD has been recognized as one of the biggest unmet needs in the field of BD. Recently, the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) was developed to be applicable to the full range of anxiety and mood disorders, based on converging evidence from genetics, cognitive and affective neuroscience, and behavioral research suggesting common, core emotion-related pathology. Here, the authors present a preliminary evaluation of the efficacy of the UP for the treatment of BD with comorbid anxiety, in a clinical replication series consisting of three cases.

AB By the late 1970s it was clear that cognitive and behavioral therapies were promising alternatives to antidepressant medications for treatment of depressed outpatients. One such model of therapy, Social Skills Training, was developed by Michel Hersen and his colleagues specifically for treatment of depressed women. Professor Hersen and his colleagues obtained funding from the National Institute of Mental Health to conduct the first well-controlled randomized trial of this intervention, contrasting Social Skills Training, in combination with either placebo or active amitriptyline, against two active standards: amitriptyline alone and time-limited, psychodynamic psychotherapy in combination with placebo. The results of this study suggested that Social Skills Training (plus placebo) was at least as effective as amitriptyline alone or psychodynamic psychotherapy (plus placebo), with superior mode-specific effects on measures of social skill. The current narrative, which provides an autobiographical perspective of four critical years (1980-1984) in the early career of the author that were intertwined with the conduct and completion of this clinical trial, is an homage to Professor Hersen's talents as a supervisor, researcher, and mentor.

AB Effectiveness of exposure therapy for posttraumatic stress disorder (PTSD) may be adversely influenced by comorbid disorders. The present study investigated behavioral activation and therapeutic exposure (BA-TE), a new integrated treatment designed specifically for comorbid symptoms of PTSD and depression. Combat veterans with PTSD (N = 117) completed eight sessions of BA-TE that included two phases of treatment: (a) behavioral activation (BA) in which some activities involved situational exposures and (b) BA and situational exposures with imaginal exposures. Findings supported improvements in symptoms of PTSD, and overlapping symptoms of PTSD and depression, but not in nonoverlapping symptoms of depression. The findings also demonstrated a relatively consistent rate of change in PTSD and depression symptoms during BA-TE, despite the addition of imaginal exposures midway through the treatment. Together, these findings provide preliminary support for BA-TE as a treatment for PTSD and depression, and highlight the utility of transdiagnostic treatments in addressing comorbidity and symptom overlap.

AB Cancers are complex multifactorial diseases. For centuries, conventional organ-based classification system (i.e., breast cancer, lung cancer, colon cancer, colorectal cancer, prostate cancer, lymphoma, leukemia, and so on) has been utilized. Recently, molecular diagnostics has become an essential component in clinical decision-making. However, tumor evolution and behavior cannot accurately be predicted, despite numerous research studies reporting promising tumor biomarkers. To advance molecular diagnostics, a better understanding of intratumor and intertumor heterogeneity is essential. Tumor cells interact with the extracellular matrix and host non-neoplastic cells in the tumor microenvironment, which is influenced by genomic variation, hormones, and dietary, lifestyle and environmental exposures, implicated by molecular pathological epidemiology. Essentially, each tumor possesses its own unique characteristics in terms of molecular make-up, tumor microenvironment and interactomes within and between neoplastic and host cells. Starting from the unique tumor concept and paradigm, we can better classify tumors by molecular methods, and move closer toward personalized cancer medicine and prevention.

AB Objectives The aim of this study was to compare, in a large all-comers registry, major adverse cardiac and cerebrovascular events (MACCE) after percutaneous coronary intervention (PCI) with first-generation drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) in unprotected left main coronary artery (ULMCA) stenosis.
Background Percutaneous coronary intervention with DES implantation in ULMCA has been shown to be a feasible and safe approach at midterm clinical follow-up.
Methods All consecutive patients with ULMCA stenosis treated by PCI with DES versus CABG were analyzed in this multinational registry. A propensity score analysis was performed to adjust for baseline differences in the overall cohort.
Results In total 2,775 patients were included: 1,874 were treated with PCI versus 901 with CABG. At 1,295 (interquartile range: 928 to 1,713) days, there were no differences, at the adjusted analysis, in the primary composite endpoint of death, cerebrovascular accidents, and myocardial infarction (MI) (adjusted hazard ratio [HR]: 1.11; 95% confidence interval [CI]: 0.85 to 1.42; p = 0.47), mortality (adjusted HR: 1.16; 95% CI: 0.87 to 1.55; p = 0.32), or composite endpoint of death and MI (adjusted HR: 1.25; 95% CI: 0.95 to 1.64; p = 0.11). An advantage of CABG over PCI was observed in the composite secondary endpoint of MACCE (adjusted HR: 1.64; 95% CI: 1.33 to 2.03; p < 0.0001), driven exclusively by the higher incidence of target vessel revascularization with PCI.
Conclusions In our multinational all-comers registry, no difference was observed in the occurrence of death, cerebrovascular accidents, and MI between PCI and CABG. An advantage of CABG over PCI was observed in the incidence of MACCE, driven by the higher incidence of target vessel revascularization with PCI.

AB Hormone therapy is the mainstay of adjuvant treatment for hormone receptor positive (HR-positive) nonmetastatic breast cancer. We evaluated adjuvant hormone therapy (AHT) initiation among Medicaid-insured women aged 2164years with stage IIII HR-positive breast cancer. We used multivariable logistic regression to identify independent predictors of AHT initiation. Within 1year of diagnosis, 68% (1049/1538) initiated AHT; by 18months, 80% (1168/1461) initiated AHT. In multivariable analysis, women less likely to initiate AHT had more comorbidity (epsilon 2 vs none: adjusted odds ratio (AOR)=0.55; 95% CI=0.32 to 0.97), more advanced disease (stage III vs I: AOR=0.27; 95% CI=0.18 to 0.39), and no radiation after breast conserving surgery (AOR=0.15; 95% CI=0.10 to 0.22). Race, age, and history of mental health disorders were not independently associated with initiation of AHT. Among initiators of AHT, 58% (604/1049) were adherent to treatment for the year after initiation. Despite comprehensive prescription coverage, only 39% (604/1538) received optimal AHT including prompt initiation and adherence for the year after treatment. Partnerships between Medicaid programs and cancer registries may help identify at-risk women and facilitate the implementation of quality improvement strategies.

AB Objective To explore the associations among dating violence (DV), aggression, relationship power, and depressive symptoms. Design A cross-sectional survey secondary analysis. Setting An urban, school based health center, October, 2009 through May, 2009. Participants Low income, adolescent girls (n = 155), ages 1418. Methods Descriptive and bivariate analyses were conducted to illustrate patterns and associations among variables. Key variables included depressive symptoms, DV victimization and aggression, and relationship power. We used mediation analyses to determine the direct and indirect effects among variables. Results Both DV victimization and aggression were reported frequently. Furthermore, DV victimization had a significant direct effect on depression and an indirect effect through relationship power. Depressive symptoms and relationship power were associated with DV aggression. Although relationship power did have a significant inverse effect on depressive symptoms, it was not through DV aggression. Conclusions Complex associations remain between mental health and DV; however, relationship power partially accounts for DV victimization's effect on depressive symptoms. Depressive symptoms are associated with DV victimization and aggression; therefore, nurses should address relationship power in clinical and community interventions.

AB Measures of head injury, executive functioning, and intelligence were given to a community sample composed of 102 male perpetrators of intimate partner aggression (IPA) and 62 nonaggressive men. A history of head injury and lower mean score on a measure of verbal intelligence were associated with the frequency of male-perpetrated physical IPA as reported by male perpetrators and their female partners. Lower mean scores on a measure of verbal intelligence also predicted frequency of psychological IPA perpetration. Using the perpetrator subtypes outlined by Holtzworth-Munroe et al. (2000), analyses revealed that compared with other groups, the most severely aggressive subtypes (i.e., borderline-dysphoric and generally violent-antisocial) were the most likely to report a history of head injury and to have significantly lower mean scores on a neuropsychological test of verbal intelligence. The possible role of neuropsychological factors in IPA perpetration and implications for prevention and intervention programs are discussed.

AB The propensity to engage in risk behaviors confers an elevated risk of HIV and other infectious disease transmission in opioid-dependent populations. Although drug abuse treatment may decrease drug-related risk behaviors such as needle-sharing, additional intervention may be needed to reduce HIV risk behavior. In this investigation, we assessed sexual HIV risk behaviors in opioid-dependent patients who were engaging in regular drug use despite ongoing counseling and methadone maintenance therapy. Potential risk and protective factors for engaging in sexual HIV risk behavior were examined. Taking into account demographic, psychiatric, substance use, and psychological variables, the only significant predictor of risk behavior was age. Specifically, younger patients were more likely to engage in sexual HIV risk behavior. The implications of these results for reducing sexual HIV risk behavior and for HIV prevention in methadone-maintained, treatment-refractory opioid-dependent patients are discussed.

AB The healthy microbiota show remarkable variability within and among individuals. In addition to external exposures, ecological relationships (both oppositional and symbiotic) between microbial inhabitants are important contributors to this variation. It is thus of interest to assess what relationships might exist among microbes and determine their underlying reasons. The initial Human Microbiome Project (HMP) cohort, comprising 239 individuals and 18 different microbial habitats, provides an unprecedented resource to detect, catalog, and analyze such relationships. Here, we applied an ensemble method based on multiple similarity measures in combination with generalized boosted linear models (GBLMs) to taxonomic marker (16S rRNA gene) profiles of this cohort, resulting in a global network of 3,005 significant co-occurrence and co-exclusion relationships between 197 clades occurring throughout the human microbiome. This network revealed strong niche specialization, with most microbial associations occurring within body sites and a number of accompanying inter-body site relationships. Microbial communities within the oropharynx grouped into three distinct habitats, which themselves showed no direct influence on the composition of the gut microbiota. Conversely, niches such as the vagina demonstrated little to no decomposition into region-specific interactions. Diverse mechanisms underlay individual interactions, with some such as the co-exclusion of Porphyromonaceae family members and Streptococcus in the subgingival plaque supported by known biochemical dependencies. These differences varied among broad phylogenetic groups as well, with the Bacilli and Fusobacteria, for example, both enriched for exclusion of taxa from other clades. Comparing phylogenetic versus functional similarities among bacteria, we show that dominant commensal taxa (such as Prevotellaceae and Bacteroides in the gut) often compete, while potential pathogens (e. g. Treponema and Prevotella in the dental plaque) are more likely to co-occur in complementary niches. This approach thus serves to open new opportunities for future targeted mechanistic studies of the microbial ecology of the human microbiome.

AB High coverage whole genome sequencing provides near complete information about genetic variation. However, other technologies can be more efficient in some settings by (a) reducing redundant coverage within samples and (b) exploiting patterns of genetic variation across samples. To characterize as many samples as possible, many genetic studies therefore employ lower coverage sequencing or SNP array genotyping coupled to statistical imputation. To compare these approaches individually and in conjunction, we developed a statistical framework to estimate genotypes jointly from sequence reads, array intensities, and imputation. In European samples, we find similar sensitivity (89%) and specificity (99.6%) from imputation with either 1 x sequencing or 1 M SNP arrays. Sensitivity is increased, particularly for low-frequency polymorphisms (MAF <5%), when low coverage sequence reads are added to dense genome-wide SNP arrays - the converse, however, is not true. At sites where sequence reads and array intensities produce different sample genotypes, joint analysis reduces genotype errors and identifies novel error modes. Our joint framework informs the use of next-generation sequencing in genome wide association studies and supports development of improved methods for genotype calling.

AB Objectives: To explore an alternative approach to quantifying the burden of side effects at 1 year after treatment for prostate cancer among both patients and their partners. Methods: We analyzed data from 75 couples in the Family and Cancer Therapy Selection study. Paired patients and family members were independently asked about their willingness to pay (WTP) for a hypothetical new treatment that cures prostate cancer without side effects if they could reconsider their treatment decision by indicating the maximum amount they would be willing to pay given 11 separate "bids" ranging from $0 to $1500 per month. Descriptive and regression analyses were conducted for patients and family members controlling for sociodemographic characteristics and health status; Spearman correlations were also examined. Results: Among 75 couples analyzed, the income-adjusted mean WTP estimates per month were $400.8 (standard error [SE] $54.3) for patients and $650.2 (SE 72.2) for family members. The WTP between patients and family members was correlated (Pearson rho 0.30; P = 0.01). After adjusting for covariates, the adjusted mean WTP per month was $588.1 (SE 65.77) for patients and $819.4 (SE 74.33) for family members. Wanting to avoid side effects at baseline predicted higher WTP for patients (P = 0.010). Experiencing sexual side effects was predictive of higher WTP for family members (P = 0.047). Conclusions: Fairly high WTP amounts for a hypothetical treatment without side effects suggests that patients and their partners are experiencing important burdens 1 year after treatment. The higher amounts partners are willing to pay and the correlation with sexual side effects suggest that they are perceptive of significant treatment burdens.

AB A minority of asthma patients have disease that proves difficult to control with usual medications and experience ongoing symptoms, poor quality of life, and limitations in activity and/or frequent asthma exacerbations. This group of patients accounts for much of the expense associated with asthma care and is the focus of national and international collaborative study groups. Distinguishing between "difficult-to-manage asthma" and truly "therapy-resistant asthma" is helpful and promotes a systematic consideration of contributory factors. Critical evaluation of factors contributing to difficult-to-manage asthma including adverse environment, comorbidities, nonadherence, and incorrect diagnosis is recommended in a systematic fashion in Part 1 of this contribution.

AB Patients with severe asthma have considerable morbidity related to their asthma and are at risk for serious, life-threatening exacerbations. Their management requires an intensive and comprehensive approach, including attention to reducing exposure to environmental inciters of airway inflammation and triggers of symptoms, patient education (including an asthma action plan), and opportunity for close patient-provider communication. Approved medical options include the lipoxygenase inhibitor, zileuton; the anti-immunoglobulin E monoclonal antibody, omalizumab; and bronchial thermoplasty. Nonapproved interventions of potential benefit are ultrahigh-dose inhaled corticosteroids, anticholinergic bronchodilators (tiotropium), macrolide antibiotics, and vitamin D supplementation for the vitamin D-deficient patient. Potentially toxic, "steroid-sparing" therapies such as methotrexate, cyclosporine, and etanercept are best reserved for patients participating in clinical trials. Recognition of specific subtypes of patients with therapy-resistant asthma permits more targeted treatment approaches, such as for aspirin-sensitive asthma, persistent eosinophilic asthma, asthma complicated by allergic bronchopulmonary aspergillosis, asthma with persistent airflow obstruction, and asthma with life-threatening (near fatal) asthmatic attacks. Novel therapies based on an improved understanding of the pathobiology of therapy-resistant asthma are greatly needed.

AB The phosphoinositide 3-kinase (PI3K)/AKT and RAF/MEK/ERK signaling pathways are activated in a wide range of human cancers. In many cases, concomitant inhibition of both pathways is necessary to block proliferation and induce cell death and tumor shrinkage. Several feedback systems have been described in which inhibition of one intracellular pathway leads to activation of a parallel signaling pathway, thereby decreasing the effectiveness of single-agent targeted therapies. In this study, we describe a feedback mechanism in which MEK inhibition leads to activation of PI3K/AKT signaling in EGFR and HER2-driven cancers. We found thatMEKinhibitor-induced activation of PI3K/AKT resulted from hyperactivation of ERBB3 as a result of the loss of an inhibitory threonine phosphorylation in the conserved juxtamembrane domains of EGFR and HER2. Mutation of this amino acid led to increased ERBB receptor activation and upregulation of the ERBB3/PI3K/AKT signaling pathway, which was no longer responsive to MEK inhibition. Taken together, these results elucidate an important, dominant feedback network regulating central oncogenic pathways in human cancer. Cancer Res; 72(13); 3228-37. (C) 2012 AACR.

AB Frequent gene amplification of the receptor-activated calcium-dependent chloride channel TMEM16A (TAOS2 or ANO1) has been reported in several malignancies. However, its involvement in human tumorigenesis has not been previously studied. Here, we show a functional role for TMEM16A in tumor growth. We found TMEM16A overexpression in 80% of head and neck squamous cell carcinoma (SCCHN), which correlated with decreased overall survival in patients with SCCHN. TMEM16A overexpression significantly promoted anchorage-independent growth in vitro, and loss of TMEM16A resulted in inhibition of tumor growth both in vitro and in vivo. Mechanistically, TMEM16A-induced cancer cell proliferation and tumor growth were accompanied by an increase in extracellular signal-regulated kinase (ERK) 1/2 activation and cyclin D1 induction. Pharmacologic inhibition of MEK/ERK and genetic inactivation of ERK1/2 (using siRNA and dominant-negative constructs) abrogated the growth effect of TMEM16A, indicating a role for mitogen-activated protein kinase (MAPK) activation in TMEM16A-mediated proliferation. In addition, a developmental small-molecule inhibitor of TMEM16A, T16A-inh01 (A01), abrogated tumor cell proliferation in vitro. Together, our findings provide a mechanistic analysis of the tumorigenic properties of TMEM16A, which represents a potentially novel therapeutic target. The development of small-molecule inhibitors against TMEM16A may be clinically relevant for treatment of human cancers, including SCCHN. Cancer Res; 72(13); 3270-81. (C) 2012 AACR.

TI Combined EGFR/MET or EGFR/HSP90 Inhibition Is Effective in the Treatment

AB Tyrosine kinase inhibitors (TKI) that target the EGF receptor (EGFR) are effective in most non-small cell lung carcinoma (NSCLC) patients whose tumors harbor activating EGFR kinase domain mutations. Unfortunately, acquired resistance eventually emerges in these chronically treated cancers. Two of the most common mechanisms of acquired resistance to TKIs seen clinically are the acquisition of a secondary "gatekeeper" T790M EGFR mutation that increases the affinity of mutant EGFR for ATP and activation of MET to offset the loss of EGFR signaling. Although up to one-third of patient tumors resistant to reversible EGFR TKIs harbor concurrent T790M mutation and MET amplification, potential therapies for these tumors have not been modeled in vivo. In this study, we developed a preclinical platform to evaluate potential therapies by generating transgenic mouse lung cancer models expressing EGFR-mutant Del19-T790M or L858R-T790M, each with concurrent MET overexpression. We found that monotherapy targeting EGFR or MET alone did not produce significant tumor regression. In contrast, combination therapies targeting EGFR and MET simultaneously were highly efficacious against EGFR TKI-resistant tumors codriven by Del19-T790M or L858R-T790M and MET. Our findings therefore provide an in vivo model of intrinsic resistance to reversible TKIs and offer preclinical proof-of-principle that combination targeting of EGFR and MET may benefit patients with NSCLC.

AB BACKGROUND: Optimizing postdischarge medication adherence is a target for avoiding adverse events. Nevertheless, few studies have focused on predictors of postdischarge medication adherence. METHODS: The Pharmacist Intervention for Low Literacy in Cardiovascular Disease (PILL-CVD) study used counseling and follow-up to improve postdischarge medication safety. In this secondary data analysis, we analyzed predictors of self-reported medication adherence after discharge. Based on an interview at 30-days postdischarge, an adherence score was calculated as the mean adherence in the previous week of all regularly scheduled medications. Multivariable linear regression was used to determine the independent predictors of postdischarge adherence. RESULTS: The mean age of the 646 included patients was 61.2 years, and they were prescribed an average of 8 daily medications. The mean postdischarge adherence score was 95% (standard deviation [SD] = 10.2%). For every 10-year increase in age, there was a 1% absolute increase in postdischarge adherence (95% confidence interval [CI] 0.4% to 2.0%). Compared to patients with private insurance, patients with Medicaid were 4.5% less adherent (95% CI -7.6% to -1.4%). For every 1-point increase in baseline medication adherence score, as measured by the 4-item Morisky score, there was a 1.6% absolute increase in postdischarge medication adherence (95% CI 0.8% to 2.4%). Surprisingly, health literacy was not an independent predictor of postdischarge adherence. CONCLUSIONS: In patients hospitalized for cardiovascular disease, predictors of lower medication adherence postdischarge included younger age, Medicaid insurance, and baseline nonadherence. These factors can help predict patients who may benefit from further interventions. Journal of Hospital Medicine 2012;. (C) 2012 Society of Hospital Medicine

AB To elucidate the role of the hippocampus in unaware relational memory, the present study examined the performance of amnesic patients with medial temporal lobe (MTL) lesions on a cued category-exemplar generation task. In contrast to a prior study in which amnesic patients showed impaired performance.(Verfaellie et al., Cognitive, Affective, and Behavioral Neuroscience, 2006, 6, 91-101), the current study employed a task that required active processing of the context word at test. In this version of the task, amnesic patients, like control participants, showed enhanced category exemplar priming when the context word associated with the target at study was reinstated at test. The finding of intact implicit memory for novel associations following hippocampal lesions in a task that requires flexible use of retrieval cues is inconsistent with a relational memory view that suggests that the hippocampus is critical for all forms of relational memory, regardless of awareness. Instead, it suggests that unaware memory for within-domain associations does not require MTL mediation. Published by Elsevier Ltd.

AB Personalized medicine requires the identification of unambiguous prognostic and predictive biomarkers to inform therapeutic decisions. Within this context, the management of lymph node-negative breast cancer is the subject of much debate with particular emphasis on the requirement for adjuvant chemotherapy. The identification of prognostic and predictive biomarkers in this group of patients is crucial. Here, we demonstrate by tissue microarray and automated image analysis that the cocaine- and amphetamine-regulated transcript (CART) is expressed in primary and metastatic breast cancer and is an independent poor prognostic factor in estrogen receptor (ER)-positive, lymph node-negative tumors in two separate breast cancer cohorts (n = 690; P = 0.002, 0.013). We also show that CART increases the transcriptional activity of ER alpha in a ligand-independent manner via the mitogen-activated protein kinase pathway and that CART stimulates an autocrine/paracrine loop within tumor cells to amplify the CART signal. Additionally, we demonstrate that CART expression in ER-positive breast cancer cell lines protects against tamoxifen-mediated cell death and that high CART expression predicts disease outcome in tamoxifen-treated patients in vivo in three independent breast cancer cohorts. We believe that CART profiling will help facilitate stratification of lymph node-negative breast cancer patients into high- and low-risk categories and allow for the personalization of therapy.

AB Objectives: To determine whether fear avoidance beliefs (FABs) in older adults with chronic low back pain (CLBP) are significantly associated with gait speed decline and/or self-report of greater disability.
Design: Cross-sectional analysis.
Setting: An academic medical center (single site).
Participants: Two hundred English-speaking participants aged 65 years and older with CLBP every day or almost every day of moderate or greater intensity for >= 3 months.
Main Outcome Measurements: The physical activity portion of the FAB questionnaire assessed FABs. Disability was measured with gait speed and the Roland Morris Questionnaire. Covariates measured included age, gender, body mass index, chronic disease (Cumulative Illness Rating Scale), depression (Geriatric Depression Scale), and pain (McGill Pain Questionnaire Short Form).
Results: FABs were significantly associated with the Roland Morris Questionnaire (P < .0001) and gait speed (P = .002) after controlling for all covariates.
Conclusion: FABs related to physical activity in older adults with CLBP were significantly associated with both self-reported and performance-based disability after controlling for known confounders. Previous studies have reported similar associations between self-reported measures of disabling back pain and FABs. Ours is the first study to examine the relationship between FAB and gait speed, a powerful predictor of morbidity and mortality. Future work should examine whether targeting fear avoidance in addition to other psychosocial measures in older adults with CLBP improves gait speed and functional independence. PM R 2012;4:493-497

AB Background
Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that delivers low-intensity, direct current to cortical areas facilitating or inhibiting spontaneous neuronal activity. In the past 10 years, tDCS physiologic mechanisms of action have been intensively investigated giving support for the investigation of its applications in clinical neuropsychiatry and rehabilitation. However, new methodologic, ethical, and regulatory issues emerge when translating the findings of preclinical and phase I studies into phase II and III clinical studies. The aim of this comprehensive review is to discuss the key challenges of this process and possible methods to address them.
Methods
We convened a workgroup of researchers in the field to review, discuss, and provide updates and key challenges of tDCS use in clinical research.
Main Findings/Discussion
We reviewed several basic and clinical studies in the field and identified potential limitations, taking into account the particularities of the technique. We review and discuss the findings into four topics: (1) mechanisms of action of tDCS, parameters of use and computer-based human brain modeling investigating electric current fields and magnitude induced by tDCS; (2) methodologic aspects related to the clinical research of tDCS as divided according to study phase (ie, preclinical, phase I, phase H, and phase HI studies); (3) ethical and regulatory concerns; and (4) future directions regarding novel approaches, novel devices, and future studies involving tDCS. Finally, we propose some alternative methods to facilitate clinical research on tDCS. (C) 2012 Elsevier Inc. All rights reserved.

AB The present study was performed to evaluate the significance of biologic subtype and 21-gene recurrence score relative to local recurrence and local-regional recurrence after breast conservation treatment with radiation. Eastern Cooperative Oncology Group E2197 was a prospective randomized clinical trial that compared two adjuvant systemic chemotherapy regimens for patients with operable breast carcinoma with 1-3 positive lymph nodes or negative lymph nodes with tumor size > 1.0 cm. The study population was a subset of 388 patients with known 21-gene recurrence score and treated with breast conservation surgery, systemic chemotherapy, and definitive radiation treatment. Median follow-up was 9.7 years (range = 3.7-11.6 years). The 10-year rates of local recurrence and local-regional recurrence were 5.4 % and 6.6 %, respectively. Neither biologic subtype nor 21-gene Recurrence Score was associated with local recurrence or local-regional recurrence on univariate or multivariate analyses (all P a parts per thousand yen 0.12). The 10-year rates of local recurrence were 4.9 % for hormone receptor positive, HER2-negative tumors, 6.0 % for triple negative tumors, and 6.4 % for HER2-positive tumors (P = 0.76), and the 10-year rates of local-regional recurrence were 6.3, 6.9, and 7.2 %, respectively (P = 0.79). For hormone receptor-positive tumors, the 10-year rates of local recurrence were 3.2, 2.9, and 10.1 % for low, intermediate, and high 21-gene recurrence score, respectively (P = 0.17), and the 10-year rates of local-regional recurrence were 3.8, 5.1, and 12.0 %, respectively (P = 0.12). For hormone receptor-positive tumors, the 21-gene recurrence score evaluated as a continuous variable was significant for local-regional recurrence (hazard ratio 2.66; P = 0.03). The 10-year rates of local recurrence and local-regional recurrence were reasonably low in all subsets of patients. Neither biologic subtype nor 21-gene recurrence score should preclude breast conservation treatment with radiation.

AB The purpose of this study is to evaluate the relationship between TOP2A RNA expression and recurrence in patients with operable estrogen receptor (ER)-positive breast cancer. We evaluated TOP2A expression in a pooled analysis of four independent datasets with gene expression data including 752 patients with early stage, ER-positive, HER2-negative breast cancer, most of whom received either no adjuvant therapy or only endocrine therapy without chemotherapy. We also used an algorithm to simulate the Oncotype DX Recurrence Score (simRS) and the proliferation component of the Recurrence Score (simPS). Results are expressed as the hazard ratio (HR) for estimates of the effect of a 1SD increase in the value of the log gene expression (x + 1SD vs. x) as a continuous function. TOP2A expression was significantly associated with recurrence (HR 1.56, p < 0.0001), and after adjustment for simRS (HR 1.26, p = 0.003). TOP2A correlated somewhat with simRS (0.45), but more strongly with simPS (0.69). For those with an intermediate simRS, high TOP2A expression (above the median) was associated with significantly higher relapse rates at 5 years (HR 1.82, p = 0.007). TOP2A expression provides prognostic information in patients with ER-positive, HER2-negative breast cancer, a population known to have low incidence of TOP2A gene alterations. These findings confirm prior reports indicating that TOP2A expression provides prognostic information in ER-positive breast cancer. TOP2A expression may also be useful for identifying those with an intermediate RS who are more likely to relapse, although additional validation in datasets including measured rather than simulated RS will be required.

AB Four loci have been associated with pancreatic cancer through genome-wide association studies (GWAS). Pathway-based analysis of GWAS data is a complementary approach to identify groups of genes or biological pathways enriched with disease-associated single-nucleotide polymorphisms (SNPs) whose individual effect sizes may be too small to be detected by standard single-locus methods. We used the adaptive rank truncated product method in a pathway-based analysis of GWAS data from 3851 pancreatic cancer cases and 3934 control participants pooled from 12 cohort studies and 8 case-control studies (PanScan). We compiled 23 biological pathways hypothesized to be relevant to pancreatic cancer and observed a nominal association between pancreatic cancer and five pathways (P < 0.05), i.e. pancreatic development, Helicobacter pylori lacto/neolacto, hedgehog, Th1/Th2 immune response and apoptosis (P = 2.0 x 10(-6), 1.6 x 10(-5), 0.0019, 0.019 and 0.023, respectively). After excluding previously identified genes from the original GWAS in three pathways (NR5A2, ABO and SHH), the pancreatic development pathway remained significant (P = 8.3 x 10(-5)), whereas the others did not. The most significant genes (P < 0.01) in the five pathways were NR5A2, HNF1A, HNF4G and PDX1 for pancreatic development; ABO for H.pylori lacto/neolacto; SHH for hedgehog; TGFBR2 and CCL18 for Th1/Th2 immune response and MAPK8 and BCL2L11 for apoptosis. Our results provide a link between inherited variation in genes important for pancreatic development and cancer and show that pathway-based approaches to analysis of GWAS data can yield important insights into the collective role of genetic risk variants in cancer.

AB Background: Eligibility for thrombolysis as an acute stroke treatment is determined through the use of unenhanced noncontrast computed tomography (CT), time since stroke onset, and patient history. Assessing penumbral patterns, which can be examined only through the use of diagnostic technologies such as magnetic resonance imaging (MRI) and perfusion CT (CTP), may be able to better select patients for thrombolysis. However, trade-offs in terms of administration time and cost may affect the value of using these diagnostic studies.
Objective: We examined the trade-offs among patient selection via usual care with CT, usual care plus MRI using diffusion-weighted and perfusion imaging, and usual care plus CTP for their effect on costs and outcomes when diagnosing stroke and selecting candidates for thrombolysis in the United Kingdom.
Methods: A decision-analytic model was developed. Efficacy and utilities were obtained from published studies. Costs were obtained from standard UK costing sources and were supplemented with data from the published literature. Outcomes included a favorable outcome (modified Rankin Scale score <2), costs, life-years, quality-adjusted life-years, and incremental cost-effectiveness ratios.
Results: Compared with usual care selection, adding CTP or MRI to better select patients for thrombolysis reduced the number of patients receiving thrombolysis by 9 and 14.6 per 1000 patients treated, respectively, while improving favorable outcome (19.2 and 17.6 per 1000 patients treated, respectively). In both scenarios, costs were decreased slightly. Both CTP and MRI selection were cost saving (more efficacious and less costly) compared with unenhanced CT selection; CTP selection was found to dominate MRI selection.
Conclusions: Adding diagnostic tests such as CTP and MRI to select UK patients for thrombolysis may be a good value for the money and may improve patient outcomes. If a preferred diagnostic test had to be chosen based on economic value, CTP might be the best compromise between unenhanced CT selection and MRI selection.

AB Loco-regional therapy has been developed to reduce waitlist dropout in patients with hepatocellular carcinoma (HCC) awaiting liver transplantation. We evaluated the probability of transplantation and waitlist dropout, and analyzed risk factors for waitlist dropout, in 76 patients with HCC from September 2004 to August 2006. Seventy-three (96.1%) patients received one or more preoperative loco-regional treatments and 55 (72.3%) received an orthotopic liver transplantation with a median wait time of seven months (range, 226 months). There were 11 dropouts (14.5%) associated with tumor progression or hepatic decompensation (median waiting time; 5.4 months and range, 0.413 months). Cumulative probabilities of transplantation at three, six, nine, 12, 15, and 18 months were 5.4%, 35.4%, 67.5%, 78.8%, 80.7%, and 80.7%, respectively and those of waitlist dropout at three, six, nine, 12, 15, and 18 months were 3.9%, 8.7%, 12.8%, 22.9%, 29.3%, and 29.3%, respectively. A laboratory model for end-stage liver disease (MELD) score >15 or multiple tumors at the time of UNOS listing were significant risk factors for waitlist dropout (p = 0.006 and 0.026, respectively). Patients with HCC being managed with loco-regional therapy who have a laboratory MELD score >15 or multiple tumors should be considered for earlier access to liver transplantation to prevent waitlist dropout.

AB Objective: To assess the effect of hospital admission on glycemic control in patients with diabetes up to 1 year after discharge.
Methods: We retrospectively studied 826 adults with diabetes admitted to a tertiary care medical center and with available hemoglobin A(1c) (A1C) values for 6 months before admission and 1 year after discharge. We compared them with 826 nonhospitalized adults with diabetes matched for age, sex, race, comorbidity, and baseline A1C level. We determined the change in A1C value relative to hospitalization and baseline A1C level by using multivariate random effects models for repeated measures. Logistic regression analysis was performed to determine predictors of achieving recommended A1C levels at 1 year.
Results: Patients with baseline A1C levels >= 9% had an adjusted rate of change in A1C value of -0.10% per month (95% confidence interval [CI], -0.18 to -0.022; P = .012) during the course of I year, without significant differences between hospitalized and nonhospitalized patients in the mean rate of change. Hospitalized patients, however, were less likely to achieve an A1C goal of <= 7% at 1 year (odds ratio, 0.68; 95% CI, 0.55 to 0.86; P<.001) or an A1C of <8% at 1 year (odds ratio, 0.62; 95% CI, 0.48 to 0.81; P<.001) in comparison with the nonhospitalized patients.
Conclusion: Despite an overall trend toward improved glycemia over time, hospitalized patients with uncontrolled diabetes were less likely to achieve glycemic targets at 1 year in comparison with matched nonhospitalized patients. These results suggest a missed opportunity to improve long-term glycemic control in hospitalized patients with diabetes. (Endoer Pract. 2012;18:456-463)

AB The contribution of environmental surface contamination with pathogenic organisms to the development of health care-associated infections (HAI) has not been well defined. The microbial burden (MB) associated with commonly touched surfaces in intensive care units (ICUs) was determined by sampling six objects in 16 rooms in ICUs in three hospitals over 43 months. At month 23, copper-alloy surfaces, with inherent antimicrobial properties, were installed onto six monitored objects in 8 of 16 rooms, and the effect that this application had on the intrinsic MB present on the six objects was assessed. Census continued in rooms with and without copper for an additional 21 months. In concert with routine infection control practices, the average MB found for the six objects assessed in the clinical environment during the preintervention phase was 28 times higher (6,985 CFU/100 cm(2); n = 3,977 objects sampled) than levels proposed as benign immediately after terminal cleaning (< 250 CFU/100 cm(2)). During the intervention phase, the MB was found to be significantly lower for both the control and copper-surfaced objects. Copper was found to cause a significant (83%) reduction in the average MB found on the objects (465 CFU/100 cm(2); n = 2714 objects) compared to the controls (2,674 CFU/100 cm(2); n = 2,831 objects [P < 0.0001]). The introduction of copper surfaces to objects formerly covered with plastic, wood, stainless steel, and other materials found in the patient care environment significantly reduced the overall MB on a continuous basis, thereby providing a potentially safer environment for hospital patients, health care workers (HCWs), and visitors.

AB Quality clinical learning environments (CLE) are crucial to student education and clinical learning and are influenced by both academic and nursing service factors. The University at Buffalo School of Nursing implemented an innovative academic service partnership model for clinical education of students called a Dedicated Education Unit (DEU). The aims of this study were to (a) investigate students perceived outcomes of the DEU model on the CLE and (b) explore staff nurses' and faculty's perceived outcomes of the DEU. Qualitative and quantitative methodologies were used. Descriptive statistics and thematic analysis of focus groups are reported. Students and DEU nurses reported high scores for satisfaction. Focus group themes for students, faculty, and DEU nurse revealed appreciation for the benefits of the DEU model. The DEU is a worthwhile approach to clinical education that can enhance student's ability to receive diverse clinical experiences and access to clinical experts. Such programs can strengthen academic/service relationships.

AB Objective: To assess the usefulness of 2 rapid molecular diagnostic techniques, polymerase chain reaction (PCR) and loop-mediated isothermal amplification (LAMP), in Clostridium difficile infection (CDI).
Methods: We conducted a systematic review and meta-analysis to evaluate the accuracy of PCR and LAMP in diagnosis of CDI, including studies that used toxigenic culture or cytotoxicity assay as reference standard.
Results: A search of PubMed and CinAHL medical databases yielded 25 PCR studies, including 11,801 samples that met inclusion criteria and 6 heterogeneous studies that evaluated LAMP. With toxigenic culture as a standard, pooled sensitivity was 0.92 (95% confidence interval [Cl], 0.91-0.94); specificity, 0.94 (95% Cl, 0.94-0.95); and diagnostic odds ratio, 378 (95% Cl, 260-547). With cytotoxicity as a standard, pooled sensitivity was 0.87 (95% Cl, 0.84-0.90); specificity, 0.97 (95% Cl, 0.97-0.98); and diagnostic odds ratio, 370 (95% Cl, 226-606).
Conclusion: Polymerase chain reaction is a highly accurate test for identifying CDI. Heterogeneity in LAMP studies did not allow meta-analysis; however, further research into this promising method is warranted.

AB Objectives: This trial examined the efficacy of a stress management program in reducing neuroimaging markers of multiple sclerosis (MS) disease activity.
Methods: A total of 121 patients with relapsing forms of MS were randomized to receive stress management therapy for MS (SMT-MS) or a wait-list control condition. SMT-MS provided 16 individual treatment sessions over 24 weeks, followed by a 24-week post-treatment follow-up. The primary outcome was the cumulative number of new gadolinium-enhancing (Gd+) brain lesions on MRI at weeks 8, 16, and 24. Secondary outcomes included new or enlarging T2 MRI lesions, brain volume change, clinical exacerbation, and stress.
Results: SMT-MS resulted in a reduction in cumulative Gd+ lesions (p = 0.04) and greater numbers of participants remained free of Gd+ lesions during the treatment (76.8% vs 54.7%, p = 0.02), compared to participants receiving the control treatment. SMT-MS also resulted in significantly reduced numbers of cumulative new T2 lesions (p = 0.005) and a greater number of participants remaining free of new T2 lesions (69.5% vs 42.7%, p = 0.006). These effects were no longer detectable during the 24-week post-treatment follow-up period.
Conclusions: This trial indicates that SMT-MS may be useful in reducing the development of new MRI brain lesions while patients are in treatment.
Classification of evidence: This study provides Class I evidence that SMT-MS, a manualized stress management therapy program, reduced the number of Gd+ lesions in patients with MS during a 24-week treatment period. This benefit was not sustained beyond 24 weeks, and there were no clinical benefits.

AB Two distinct Polycomb complexes, PRC1 and PRC2, collaborate to maintain epigenetic repression of key developmental loci in embryonic stem cells (ESCs). PRC1 and PRC2 have histone modifying activities, catalyzing mono-ubiquitination of histone H2A (H2AK119u1) and trimethylation of H3 lysine 27 (H3K27me3), respectively. Compared to H3K27me3, localization and the role of H2AK119u1 are not fully understood in ESCs. Here we present genome-wide H2AK119u1 maps in ESCs and identify a group of genes at which H2AK119u1 is deposited in a Ring1-dependent manner. These genes are a distinctive subset of genes with H3K27me3 enrichment and are the central targets of Polycomb silencing that are required to maintain ESC identity. We further show that the H2A ubiquitination activity of PRC1 is dispensable for its target binding and its activity to compact chromatin at Hox loci, but is indispensable for efficient repression of target genes and thereby ESC maintenance. These data demonstrate that multiple effector mechanisms including H2A ubiquitination and chromatin compaction combine to mediate PRC1-dependent repression of genes that are crucial for the maintenance of ESC identity. Utilization of these diverse effector mechanisms might provide a means to maintain a repressive state that is robust yet highly responsive to developmental cues during ES cell self-renewal and differentiation.

AB The Alternative Lengthening of Telomeres (ALT) pathway is a telomerase-independent pathway for telomere maintenance that is active in a significant subset of human cancers and in vitro immortalized cell lines. ALT is thought to involve templated extension of telomeres through homologous recombination, but the genetic or epigenetic changes that unleash ALT are not known. Recently, mutations in the ATRX/DAXX chromatin remodeling complex and histone H3.3 were found to correlate with features of ALT in pancreatic neuroendocrine cancers, pediatric glioblastomas, and other tumors of the central nervous system, suggesting that these mutations might contribute to the activation of the ALT pathway in these cancers. We have taken a comprehensive approach to deciphering ALT by applying genomic, molecular biological, and cell biological approaches to a panel of 22 ALT cell lines, including cell lines derived in vitro. Here we show that loss of ATRX protein and mutations in the ATRX gene are hallmarks of ALT-immortalized cell lines. In addition, ALT is associated with extensive genome rearrangements, marked micronucleation, defects in the G2/M checkpoint, and altered double-strand break (DSB) repair. These attributes will facilitate the diagnosis and treatment of ALT positive human cancers.

AB Many genetic and physiological treatments that extend lifespan also confer resistance to a variety of stressors, suggesting that cytoprotective mechanisms underpin the regulation of longevity. It has not been established, however, whether the induction of cytoprotective pathways is essential for lifespan extension or merely correlated. Using a panel of GFP-fused stress response genes, we identified the suites of cytoprotective pathways upregulated by 160 gene inactivations known to increase Caenorhabditis elegans longevity, including the mitochondrial UPR (hsp-6, hsp-60), the ER UPR (hsp-4), ROS response (sod-3, gst-4), and xenobiotic detoxification (gst-4). We then screened for other gene inactivations that disrupt the induction of these responses by xenobiotic or genetic triggers, identifying 29 gene inactivations required for cytoprotective gene expression. If cytoprotective responses contribute directly to lifespan extension, inactivation of these genes would be expected to compromise the extension of lifespan conferred by decreased insulin/IGF-1 signaling, caloric restriction, or the inhibition of mitochondrial function. We find that inactivation of 25 of 29 cytoprotection-regulatory genes shortens the extension of longevity normally induced by decreased insulin/IGF-1 signaling, disruption of mitochondrial function, or caloric restriction, without disrupting normal longevity nearly as dramatically. These data demonstrate that induction of cytoprotective pathways is central to longevity extension and identify a large set of new genetic components of the pathways that detect cellular damage and couple that detection to downstream cytoprotective effectors.

AB BACKGROUND: The American Academy of Pediatrics and other organizations recommend several screening tests as part of preventive care. The proportion of children who are appropriately screened and who receive follow-up care is low.
OBJECTIVE: To conduct a systematic review of the evidence for practice-based interventions to increase the proportion of patients receiving recommended screening and follow-up services in pediatric primary care.
DATA SOURCE: Medline database of journal citations.
STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS: We developed a strategy to search MEDLINE to identify relevant articles. We selected search terms to capture categories of conditions (eg, developmental disabilities, obesity), screening tests, specific interventions (eg, quality improvement initiatives, electronic records enhancements), and primary earn. We searched references of selected articles and reviewed articles suggested by experts. We included all studies with a distinct, primary care-based intervention and post-intervention screening data, and studies that focused on children and young adults (<= 21 years of age). We excluded studies of newborn screening.
STUDY APPRAISAL AND SYNTHESIS METHODS: Abstracts were screened by 2 reviewers and articles with relevant abstracts received full text review and were evaluated for inclusion criteria. A structured tool was used to abstract data from selected articles. Because of heterogeneous interventions and outcomes, we did not attempt a meta-analysis.
RESULTS: From 2547 returned titles and abstracts, 23 articles were reviewed. Nine were pre-post comparisons, 5 were randomized trials, 3 were postintervention comparisons with a control group, 3 were postintervention cross-sectional analyses only, and 3 reported time series data. Of 14 articles with preintervention or control group data and significance testing, 12 reported increases in the proportion of patients appropriately screened. Interventions were heterogeneous and often multifaceted, and several types of interventions, such as provider/staff training, electronic medical record templates/prompts, and learning collaboratives, appeared effective in improving screening quality. Few articles described interventions to track screening results or referral completion for those with abnormal tests. Data were often limited by single-site, nonrandomized design.
CONCLUSIONS: Several feasible, practice- and provider-level interventions appear to increase the quality of screening in pediatric primary care. Evidence for interventions to improve follow-up of screening tests is scant. Future research should focus on which specific interventions are most effective, whether effects are sustained over time, and what interventions improve follow-up of abnormal screening tests.

AB Background: Recent endoscopic dissection studies have redefined the postganglionic pterygopalatine autonomic pathways suggesting that neurovascular rami, termed "accessory posterolateral nerves," project directly through the palatine bone to innervate the posterolateral nasal mucosa rather than traveling with trigeminal arborizations. The goal of this study was to characterize these accessory posterolateral nerves by immunohistochemistry to determine their morphology and composition.
Methods: This is an Institutional Review Board approved study in seven patients in whom the presence of accessory posterolateral nerves were surgically identified exiting the perpendicular plate of the palatine bone and sampled. The presence of neural tissue was confirmed by hematoxylin and eosin and S-100 protein staining. Nerves were then stained with anti-human choline acetyl-transferase (ChAT; 1:100) and anti-human dopamine beta-hydroxylase (DBH; 1:100) followed by a fluorescein isothiocyanate-labeled secondary antibody to test for the presence of peripheral parasympathetic and sympathetic fibers, respectively. Human cadaveric sensory nerves were used as a negative control.
Results: All seven samples contained neural elements. Two specimens were also associated with arteries. All nerves were comprised of a single fascicle containing an approximately equal distribution of ChAT(+) and DBH+ fibers.
Conclusion: This histological study supports prior descriptions defining a newly recognized neural pathway for innervation of the nasal mucosa. Our data confirm that these accessory posterolateral nerves project directly through the perpendicular plate of the palatine bone and are composed of autonomic fibers. Recognition of this pathway may be exploited in the treatment of sinonasal disease resulting from autonomic dysregulation. (Am J Rhinol Allergy 26, 271-273, 2012; doi: 10.2500/ajra.2012.26.3804)

AB Cancer genetic counseling and testing are now integral services in progressive cancer care. There has been much debate over whether these services should be delivered by providers with specialized training in genetics or by all clinicians. Adverse outcomes resulting from cancer genetic counseling and testing performed by clinicians without specialization in genetics have been reported, but formal documentation is sparse. In this review, we present a series of national cases illustrating major patterns of errors in cancer genetic counseling and testing and the resulting impact on medical liability, health care costs, and the patients and their families.

AB Women in the United States have a 12% lifetime risk of developing breast cancer. Although only about 5% to 10% of all cases of breast cancer are attributable to a highly penetrant cancer predisposition gene, individuals who carry a mutation in one of these genes have a significantly higher risk of developing breast cancer, as well as other cancers, over their lifetime compared with the general population. The ability to distinguish those individuals at high risk allows health care providers to intervene with appropriate counseling and education, surveillance, and prevention-with the overall goal of improved survival for these individuals. This article focuses on the identification of patients at high risk for breast cancer and provides an overview of the clinical features, cancer risks, causative genes, and medical management for the most clearly described hereditary breast cancer syndromes. Newer genes that have also been implicated in familial breast cancer are also briefly reviewed.

AB The roles of renal cell carcinoma (RCC) and urothelial cancers of the upper urinary tract are often overlooked as indicators for genetic risk assessment. The key features of 5 hereditary cancer susceptibility conditions involving an increased risk for RCC are discussed. von Hippel-Lindau disease, hereditary papillary RCC, and hereditary leiomyomatosis and RCC each predispose to a specific histological type of RCC, whereas Birt-Hogg-Dube and hereditary paraganglioma/pheochromocytoma entail a variety of histologic findings. Familiarity with the rare or uncommon clinical features associated with these conditions, such as cutaneous neoplasms, paraganglioma/pheochromocytoma, and recurrent spontaneous pneumothoraces, aids in identifying patients with an underlying RCC susceptibility. A path to identifying syndromic cases lies in thorough investigation of the patient's medical history, their family history, and the histological type of RCC reported in the family. A guide to genetic predisposition testing for RCC is proposed. Upper urinary tract cancers in Lynch syndrome are also discussed.

AB Many hereditary cancer predisposition syndromes are associated with cutaneous findings, both benign and malignant. Dermatological examination and histopathology, when combined with a thorough personal and family medical history, play an important role in the diagnosis of cancer predisposition syndromes. Skin findings are an important diagnostic tool for a variety of cancer syndromes, including Cowden syndrome, Birt-Hogg-Dube , hereditary leiomyomatosis renal cell carcinoma, and others. This article focuses on the phenotype, medical management, and genetic testing for 4 hereditary cancer syndromes that include cutaneous findings: hereditary melanoma, basal cell nevus syndrome, neurofibromatosis type 1, and neurofibromatosis type 2.

AB Background: Clinical lore and research have suggested for a long time that depression and PD are closely related. We examined the validity of depression associated with PD (dPD) as a specific subtype of depression according to face validity, descriptive validity, construct validity and predictive validity.
Methods: The English literature was reviewed after searching the MEDLINE database up to June 2010.
Results: There appears to be three possible subtypes of comorbid depression: 1) patients who would have been depressed even if they had no PD (nonspecific-casual comorbid dPD), 2) patients who would have been depressed if they had had another disabling medical illness (nonspecific-reactive comorbid dPD) 3) those for which depression is directly related to the underlying pathophysiology of PD (specific comorbid dPD). These latter patients may more often present with particular clinical characteristics (descriptive validity): absence of history of depression or only within 5 years prior to onset of PD, absence of guilty thoughts and self-blame, absence of suicidal behavior, right-sided onset. However, dPD is only partly responsive to dopamine replacement and cannot be solely explained by dopamine deficiency. Other neurotransmitter systems are affected in PD and are involved in the pathophysiology of dPD. Their relative involvement however may differ from that in idiopathic depression (i.e.: lesser involvement of serotonergic systems).
Limitations: Therapeutic data are limited to few controlled trials.
Conclusions: Further research may allow differential diagnosis between dPD subtypes (i.e.: those who do and do not result from the underlying pathophysiological process of PD) and help inform treatment choice. (C) 2011 Elsevier B.V. All rights reserved.

AB Penetrating brain injury (PBI) encountered in both the military and civilian sectors results in high morbidity and mortality due to the absence of effective treatment options for survivors of the initial trauma. Developing therapies for such injuries requires a better understanding of the complex pathology involved when projectiles enter the skull and disrupt the brain parenchyma. This study presents a histological characterization of bilateral PBI using a relatively new injury model in the rat, and also investigates the implantation of a collagen scaffold into the PBI lesion as a potential treatment option. At 1 week post-PBI, the lesion was characterized by dense macrophage infiltration, evolving astrogliosis, hypervascularity, and an absence of viable neurons, oligodendrocytes, and myelinated axons. Histomorphometric analysis revealed that the PBI lesion volume expanded by 29% between 1 week and 5 weeks post-injury, resulting in formation of a large acellular cavity. Immunohistochemistry showed a decrease in the presence of CD68-positive macrophages from 1 to 5 weeks post-PBI as the necrotic tissue in the lesion was cleared, while persistent glial scarring remained in the form of upregulated GFAP expression surrounding the PBI cavity. Implanted type I collagen scaffolds remained intact with open pores after time periods of 1 week and 4 weeks in vivo, and were found to be sparsely infiltrated with macrophages, astrocytes, and endothelial cells. Collagen scaffolds appear to be an appropriate delivery vehicle for cellular and pharmacological therapeutic agents in future studies of PBI.

AB To verify in-vivo proton dose distribution, a 2-dimensional (2D) prompt-gamma measurement system, comprised of a multi-hole collimation system, a 2D array of CsI(Tl) scintillators, and a position-sensitive photomultiplier tube (PS-PMT), is under development. In the present study, to determine the optimal dimension of the measurement system, we employed a series of Monte Carlo simulations with the MCNPX code. To effectively measure the high-energy prompt gammas while minimizing background gammas, we determined the collimator hole size, collimator thickness, and scintillator length to be 0.4 x 0.4 cm(2), 15 cm, and 5 cm, respectively. Thereafter, the performance of the optimized measurement system was estimated for monoenergetic proton pencil beams. The peak locations of the prompt-gamma distributions for 80- and 150-MeV proton beams were clearly distinguished, and the correlation between the beam range and the peak location was confirmed by using the measurement system. For a 200-MeV proton beam, however, the peak location could not be determined due to the dominance of background gammas and the lateral dispersion of the proton beam at the end of the beam range. Based on these simulation results, a prototype 2D prompt-gamma measurement system currently is under construction and, upon completion, will be tested with therapeutic proton beams.

AB Purpose: To provide transmission data for broad 25-39 kVp (kilovolt peak) W/Rh and 25-49 kVp W/Al (target/filter, W-tungsten, Rh-rhodium, and Al-aluminum) x-ray beams through common shielding materials, such as lead, concrete, gypsum wallboard, wood, steel, and plate glass.
Methods: The unfiltered W-target x-ray spectra measured on a Selenia Dimensions system (Hologic Inc., Bedford, MA) set at 20-49 kVp were, respectively, filtered using 50-mu m Rh and 700-mu m Al, and were subsequently used for Monte Carlo calculations. The transmission of broad x-ray beams through shielding materials was simulated using Geant4 low energy electromagnetic physics package with photon- and electron-processes above 250 eV, including photoelectric effect, Compton scattering, and Rayleigh scattering. The calculated transmission data were fitted using Archer equation with a robust fitting algorithm.
Results: The transmission of broad x-ray beams through the above-mentioned shielding materials was calculated down to about 10(-5) for 25-39 kVp W/Rh and 25-49 kVp W/Al. The fitted results of alpha, beta and gamma in Archer equation were provided. The a values of kVp >= 40 were approximately consistent with those of NCRP Report No. 147.
Conclusions: These data provide inputs for the shielding designs of x-ray imaging facilities with W-anode x-ray beams, such as from Selenia Dimensions. (C) 2012 American Association of Physicists in Medicine. [http://dx.doi.org/10.1118/1.4725755]

AB Group B Streptococcus (GBS) is a leading cause of invasive bacterial infections in human newborns and immune-compromised adults. The pore-forming toxin (PFT) beta hemolysin/cytolysin (beta h/c) is a major virulence factor for GBS, which is generally attributed to its cytolytic functions. Here we show beta h/c has immunomodulatory properties on macrophages at sub-lytic concentrations. beta h/c-mediated activation of p38 MAPK drives expression of the anti-inflammatory and immunosuppressive cytokine IL-10, and inhibits both IL-12 and NOS2 expression in GBS-infected macrophages, which are critical factors in host defense. Isogenic mutant bacteria lacking beta h/c fail to activate p38-mediated IL-10 production in macrophages and promote increased IL-12 and NOS2 expression. Furthermore, targeted deletion of p38 in macrophages increases resistance to invasive GBS infection in mice, associated with impaired IL-10 induction and increased IL-12 production in vivo. These data suggest p38 MAPK activation by beta h/c contributes to evasion of host defense through induction of IL-10 expression and inhibition of macrophage activation, a new mechanism of action for a PFT and a novel anti-inflammatory role for p38 in the pathogenesis of invasive bacterial infection. Our studies suggest p38 MAPK may represent a new therapeutic target to blunt virulence and improve clinical outcome of invasive GBS infection.

AB Understanding host defense against microbes is key to developing new and more effective therapies for infection and inflammatory disease. However, how animals integrate multiple environmental signals and discriminate between different pathogens to mount specific and tailored responses remains poorly understood. Using the genetically tractable model host Caenorhabditis elegans and pathogenic bacterium Staphylococcus aureus, we describe an important role for hypoxia-inducible factor (HIF) in defining the specificity of the host response in the intestine. We demonstrate that loss of egl-9, a negative regulator of HIF, confers HIF-dependent enhanced susceptibility to S. aureus while increasing resistance to Pseudomonas aeruginosa. In our attempt to understand how HIF could have these apparently dichotomous roles in host defense, we find that distinct pathways separately regulate two opposing functions of HIF: the canonical pathway is important for blocking expression of a set of HIF-induced defense genes, whereas a less well understood noncanonical pathway appears to be important for allowing the expression of another distinct set of HIF-repressed defense genes. Thus, HIF can function either as a gene-specific inducer or repressor of host defense, providing a molecular mechanism by which HIF can have apparently opposing roles in defense and inflammation. Together, our observations show that HIF can set the balance between alternative pathogen-specific host responses, potentially acting as an evolutionarily conserved specificity switch in the host innate immune response.

AB Systemic lupus erythematosus (SLE) is a disease that disproportionately affects females. Despite significant research effort, the mechanisms underlying the female predominance in this disease are largely unknown. Previously, we showed that estrogen receptor alpha knockout (ER alpha KO) lupus prone female mice had significantly less pathologic renal disease and proteinuria, and significantly prolonged survival. Since autoantibody levels and number and percentage of BIT cells were not significantly impacted by ER alpha genotype, we hypothesized that the primary benefit of ERa deficiency in lupus nephritis was via modulation of the innate immune response. Using BMDCs and spleen cells/B cells from female wild-type or ER alpha KO mice, we found that ER alpha KO-derived cells have a significantly reduced inflammatory response after stimulation with TLR agonists. Our results indicate that the inflammatory response to TLR ligands is significantly impacted by the presence of ER alpha despite the absence of estradiot, and may partially explain the protective effect of ER alpha deficiency in lupus-prone animals.

AB Aims: In patients with diabetes and hypertriglyceridemia, LDL-cholesterol (LDL-C) provides an inaccurate reflection of LDL particle burden. The relative value of non-HDL-cholesterol (non-HDL-C) and apolipoprotein-B (Apo-B) in estimating cardiovascular risk is controversial. We assessed the discordance between non-HDL-C and Apo-B targets in patients with diabetes with TG 200-499 mg/dl.
Methods: Data from 1430 determinations of LDL-C, non-HDL-C, and Apo-B in ambulatory patients with diabetes were analyzed. Rates of discordance were calculated, based on the currently recommended LDL-C, non-HDL-C, and Apo-B goals.
Results: In patients with non-HDL-C goal of < 130 mg/dl, there was a discordance with Apo-B level goal of < 90 mg/dl, in 31% of samples. In patients with non-HDL-C goal of < 100 mg/dl, 6% of samples had Apo-B >= 80 and 18% had Apo-B < 80 mg/dl. Using the Apo-B goal of < 70 mg/dl, these numbers were 37% and 3.5% respectively. There was also a significant gender difference, i.e. under-estimation of risk by suggested non-HDL-C cut-offs, in females, compared to males.
Conclusions: In patients with diabetes and hypertriglyceridemia, a considerable discordance exists between non-HDL-C and Apo-B. Our data suggest a need for prospective studies to compare the relative merits of non-HDL-C and Apo-B targets in the assessment of cardiovascular risk. (C) 2012 Elsevier Ireland Ltd.

TI Discriminating clinical features of heart failure with preserved vs.

AB Heart failure (HF) is a major public health burden worldwide. Of patients presenting with HF, 3055 have a preserved ejection fraction (HFPEF) rather than a reduced ejection fraction (HFREF). Our objective was to examine discriminating clinical features in new-onset HFPEF vs. HFREF.
Of 712 participants in the Framingham Heart Study (FHS) hospitalized for new-onset HF between 1981 and 2008 (median age 81 years, 53 female), 46 had HFPEF (EF 45) and 54 had HFREF (EF 45). In multivariable logistic regression, coronary heart disease (CHD), higher heart rate, higher potassium, left bundle branch block, and ischaemic electrocardiographic changes increased the odds of HFREF; female sex and atrial fibrillation increased the odds of HFPEF. In aggregate, these clinical features predicted HF subtype with good discrimination (c-statistic 0.78). Predictors were examined in the Enhanced Feedback for Effective Cardiac Treatment (EFFECT) study. Of 4436 HF patients (median age 75 years, 47 female), 32 had HFPEF and 68 had HFREF. Distinguishing clinical features were consistent between FHS and EFFECT, with comparable discrimination in EFFECT (c-statistic 0.75). In exploratory analyses examining the traits of the intermediate EF group (EF 3555), CHD predisposed to a decrease in EF, whereas other clinical traits showed an overlapping spectrum between HFPEF and HFREF.
Multiple clinical characteristics at the time of initial HF presentation differed in participants with HFPEF vs. HFREF. While CHD was clearly associated with a lower EF, overlapping characteristics were observed in the middle of the left ventricular EF range spectrum.

TI Responses to ragweed pollen in a pollen challenge chamber versus
seasonal exposure identify allergic rhinoconjunctivitis endotypes

ID VALIDATION; NASAL; RHINITIS; ASTHMA; ONSET; UNIT
AB Background: The level of concordance between allergic symptoms induced on exposure to pollen in a pollen challenge chamber (PCC) versus the natural season is unknown.
Objective: We sought to test the hypothesis that the symptom levels of allergic rhinoconjunctivitis elicited after out-of-season exposure to short ragweed in a PCC and during the natural season for giant ragweed pollen are highly correlated.
Methods: Thirty-one ragweed-sensitive participants recorded symptoms for 15 days during the natural giant ragweed season in San Antonio, Texas. Twenty-six of these participants were challenged to short ragweed pollen in a PCC for 3 hours per day for up to 4 days.
Results: In the PCC participants were dichotomized into those in whom low versus high levels of symptoms developed slowly or rapidly (ie, slow/low vs rapid/high). Each successive exposure visit associated with a progressive increase in symptom levels that approximated those experienced during the natural season. Hierarchic clustering identified 3 endotypes: endotypes I and II reflected concordantly low (n = 7) versus high (n = 14) total symptom scores (TSSs) in both the natural season and the PCC, respectively. Accordingly, the correlation between the TSSs recorded in the natural season and in the PCC for these 21 participants was very high. Although participants with endotype III (n = 5) had greater TSSs in the natural season than in the PCC, the degree of correlation between the TSSs remained high.
Conclusions: Our findings affirm our hypothesis, underscore the high cross-reactivity between distinct pollens, and highlight the utility of the PCC to identify novel allergy endotypes that might have contrasting mechanistic underpinnings and potentially therapeutic responses.

AB The use of endoscopes via limited incisions to access areas of the forehead and cheek has allowed facial rejuvenation procedures to be performed in a way that minimizes some of the morbidities associated with more traditional approaches. The possibility of expanding the indications for these approaches arises when endoscopic, minimally invasive techniques can be applied to the excision of lesions of the upper part of the face and the midface. Such methods offer several advantages without compromising therapeutic outcome. The specific techniques used will be illustrated as they were applied in several cases.

AB Background: Human Patient Simulation (HPS) is increasingly used in medical education, but its role in Emergency Medicine (EM) residency education is uncertain. Study Objectives: The objective of this study was to evaluate the perceived effectiveness of HPS when fully integrated into an EM residency didactic curriculum. Methods: The study design was a cross-sectional survey performed in 2006, 2 years after the implementation of an integrated simulation curriculum. Fifty-four residents (postgraduate year [PGY] 1-4) of a 4-year EM residency were surveyed with demographic and curricular questions on the perceived value of simulation relative to other teaching formats. Survey items were rated on a bipolar linear numeric scale of 1 (strongly disagree) to 9 (strongly agree), with 5 being neutral. Data were analyzed using Student t-tests. Results: Forty residents responded to the survey (74% response rate). The perceived effectiveness of HPS was higher for junior residents than senior residents (8.0 vs. 6.2, respectively, p < 0.001). There were no differences in perceived effectiveness of lectures (7.8 vs. 7.9, respectively, p = 0.1), morbidity and mortality conference (8.5 vs. 8.7, respectively, p = 0.3), and trauma conference (8.4 vs. 8.8, respectively, p = 0.2) between junior and senior residents. Scores for perceptions of improvement in residency training (knowledge acquisition and clinical decision-making) after the integration of HPS into the curriculum were positive for all residents. Conclusion: Residents' perceptions of HPS integration into an EM residency curriculum are positive for both improving knowledge acquisition and learning clinical decision-making. HPS was rated as more effective during junior years than senior years, while the perceived efficacy of more traditional educational modalities remained constant throughout residency training.

(2012) Journal of Nursing Management similar to 20, 679684 Structural empowerment and anticipated turnover among behavioural health nurses Aim The aim of this pilot study was to examine the relationship between structural empowerment and anticipated turnover among behavioural health nurses. Background There have been several studies relating structural empowerment to a range of organizational characteristics and personal attributes of nurses themselves. There are also previous studies linking the key variables in the present study, but no previous research of behavioural health nurses was available. Methods A quantitative design was used for this cross-sectional pilot study. All registered nurses (RN) working on inpatient units in the study facility were invited to participate (n = 97). An anonymous survey was sent to all potential participants. Results The response rate was 53% (n = 50). The majority of participants perceived themselves as moderately empowered. There was a significant negative correlation between empowerment and anticipated turnover. Conclusion The results of this pilot study among behavioural health nurses are similar to the results among nurses working in other clinical areas. Implications for nursing management Nurse managers should be cognizant of the factors that enhance nurses perceptions of empowerment, particularly related to issues of retention and anticipated turnover among behavioural health nurses.

AB BACKGROUND: Preoperative risk stratification is commonly performed by assessing end-organ function (such as cardiac and pulmonary) to define postoperative risk. Little is known about impaired preoperative cognition and outcomes. The purpose of this study was to evaluate the impact of baseline impaired cognition on postoperative outcomes in geriatric surgery patients.
STUDY DESIGN: Subjects 65 years and older undergoing a planned elective operation requiring postoperative ICU admission were recruited prospectively. Preoperative baseline cognition was assessed using the validated Mini-Cog test. Impaired cognition was defined as a Mini-Cog score of <= 3. Delirium was assessed using the Confusion Assessment Method-ICU by a trained research team. Adverse outcomes were defined using the Veterans Affairs Surgical Quality Improvement Program definitions.
RESULTS: One hundred and eighty-six subjects were included, with a mean age of 73 +/- 6 years. Eighty-two subjects (44%) had baseline impaired cognition. The impaired cognition group had the following unadjusted outcomes: increased incidence of 1 or more postoperative complications (41% vs 24%; p = 0.011), higher incidence of delirium (78% vs 37%; p < 0.001), longer hospital stays (15 +/- 14 vs 9 +/- 9 days; p = 0.001), higher rate of discharge institutionalization (42% vs 18%; p = 0.001), and higher 6-month mortality (13% vs 5%; p = 0.040). Adjusting for potential confounders determined by univariate analysis, logistic regression found impaired cognition was still associated with the occurrence of 1 or more postoperative complications (odds ratio = 2.401; 95% CI, 1.185 +/- 4.865; p = 0.015). Kaplan-Meier survival analysis revealed higher mortality in the impaired cognition group (log-rank p = 0.008).
CONCLUSIONS: Baseline cognitive impairment in older adults undergoing major elective operations is related to adverse postoperative outcomes including increased complications, length of stay, and long-term mortality. Improved understanding of baseline cognition and surgical outcomes can aid surgical decision making in older adults. (J Am Coll Surg 2012; 215: 12-18. (C) 2012 by the American College of Surgeons)

AB BACKGROUND: Little is known about the outcomes of patients with microscopically positive (R1) resections for primary gastrointestinal stromal tumors (GIST) because existing retrospective series contain small numbers of patients. The objective of this study was to analyze factors associated with R1 resection and assess the risk of recurrence with and without imatinib.
STUDY DESIGN: We reviewed operative and pathology reports for 819 patients undergoing resection of primary GIST from the North American branch of the American College of Surgeons Oncology Group (ACOSOG) Z9000 and Z9001 clinical trials at 230 institutions testing adjuvant imatinib after resection of primary GIST. Patient, tumor, operative characteristics, factors associated with R1 resections, and disease status were analyzed.
RESULTS: Seventy-two (8.8%) patients had an R1 resection and were followed for a median of 49 months. Factors associated with R1 resection included tumor size (>= 10 cm), location (rectum), and tumor rupture. The risk of disease recurrence in R1 patients was driven largely by the presence of tumor rupture. There was no significant difference in recurrence-free survival for patients undergoing an R1 vs R0 resection of GIST with (hazard ratio [HR] 1.095, 95% CI 0.66, 1.82, p = 0.73) or without (HR 1.51, 95% CI 0.76, 2.99, p = 0.24) adjuvant imatinib.
CONCLUSIONS: Approximately 9% of 819 GIST patients had an R1 resection. Significant factors associated with R1 resection include tumor size >= 10 cm, location, and rupture. The difference in recurrence-free survival with or without imatinib therapy in those undergoing an R1 vs R0 resection was not statistically significant at a median follow-up of 4 years.

AB Background. Type 2 diabetes genetic risk testing might motivate at-risk patients to adopt diabetes prevention behaviors. However, the influence of literacy and numeracy on patient response to diabetes genetic risk is unknown. Objective. The authors investigated the association of health literacy, genetic literacy, and health numeracy with patient responses to diabetes genetic risk. Design and Measurements. Overweight patients at high phenotypic risk for type 2 diabetes were recruited for a clinical trial of diabetes genetic risk testing. At baseline, participants predicted how their motivation for lifestyle modification to prevent diabetes might change in response to hypothetical scenarios of receiving "high'' and "low'' genetic risk results. Responses were analyzed according to participants' health literacy, genetic literacy, and health numeracy. Results. Two-thirds (67%) of participants (n = 175) reported very high motivation to prevent diabetes. Despite high health literacy (92% at high school level), many participants had limited health numeracy (30%) and genetic literacy 38%). Almost all (98%) reported that high-risk genetic results would increase their motivation for lifestyle modification. In contrast, response to low-risk genetic results varied. Higher levels of health literacy (P = 0.04), genetic literacy (P = 0.02), and health numeracy (P = 0.02) were associated with an anticipated decrease in motivation for lifestyle modification in response to low-risk results. Conclusions. While patients reported that high-risk genetic results would motivate them to adopt healthy lifestyle changes, response to low-risk results varied by patient numeracy and literacy. However, anticipated responses may not correlate with true behavior change. If future research justifies the clinical use of genetic testing to motivate behavior change, it may be important to assess how patient characteristics modify that motivational effect.

DT Article
ID PITTSBURGH COMPOUND-B; LOBAR INTRACEREBRAL HEMORRHAGE; WHITE-MATTER
LESIONS; SMALL VESSEL DISEASE; MICROBLEEDS; BURDEN; BRAIN; MRI
AB Objective: We aimed to determine whether amyloid imaging can help predict the location and number of future hemorrhages in cerebral amyloid angiopathy (CAA).
Methods: We performed a longitudinal cohort study of 11 patients with CAA without dementia who underwent serial brain MRIs after baseline amyloid imaging with Pittsburgh compound B (PiB). Mean distribution volume ratio (DVR) of PiB was determined at the sites of new micro/macrobleeds identified on follow-up MRI and compared with PiB retention at "simulated" hemorrhages, randomly placed in the same subjects using a probability distribution map of CAA-hemorrhage location. Mean PiB retention at the sites of observed new bleeds was also compared to that in shells concentrically surrounding the bleeds. Finally the association between number of incident bleeds and 3 regional amyloid measures were obtained.
Results: Nine of 11 subjects had at least one new microbleed on follow-up MRI (median 4, inter-quartile range [IQR] 1-9) and 2 had 5 new intracerebral hemorrhages. Mean DVR was greater at the sites of incident bleeds (1.34, 95% confidence interval [CI] 1.23-1.46) than simulated lesions (1.14, 95% CI 1.07-1.22, p < 0.0001) in multivariable models. PiB retention decreased with increasing distance from sites of observed bleeds (p < 0.0001). Mean DVR in a superior frontal/parasagittal region of interest correlated independently with number of future hemorrhages after adjustment for relevant covariates (p = 0.003).
Conclusions: Our results provide direct evidence that new CAA-related hemorrhages occur preferentially at sites of increased amyloid deposition and suggest that PiB-PET imaging may be a useful tool in prediction of incident hemorrhages in patients with CAA. Neurology (R) 2012;79:320-326

ID SQUAMOUS-CELL CARCINOMA; IMIQUIMOD; EFFICACY; FACE; SKIN
AB Purpose: To determine the practice patterns of ophthalmic plastic surgeons regarding the management of actinic keratosis (AK) of the eyelid and periocular area.
Methods: A brief electronic survey was distributed to members of the American Society of Ophthalmic Plastic and Reconstructive Surgery requesting their demographic information and treatment approaches to AK.
Results: One hundred and seven of 523 (20.5%) American Society of Ophthalmic Plastic and Reconstructive Surgery members completed the survey. Most respondents treat AK < 2 mm from the eyelid margin by excision with permanent pathology (62.6%), followed by referral for Mohs excision (10.3%) and excision with frozen section control (9.3%). Similar responses were recorded for the treatment of AK > 2 mm from the eyelid margin, with most respondents treating by excision with permanent pathology (56.1%), followed by referral to dermatology for Mohs or non-Mohs treatment and topical chemotherapy (8.4% each).
Conclusion: Although most American Society of Ophthalmic Plastic and Reconstructive Surgery members use excisional biopsy with permanent section pathology control of margins for the treatment of AK of the eyelid and periocular region, multiple alternative treatment approaches are also used.

AB We present a case with a nontraumatic subperiosteal orbital hematoma as a presenting sign of chronic myelogenous leukemia. A previously healthy 34 year-old man presented with a 2-day history of right upper eyelid swelling. CT scan revealed a subperiosteal mass, and routine blood tests revealed a white blood cell count of 290,000/mu l with normal platelet count. Chronic myelogenous leukemia was diagnosed based on a subsequent bone marrow biopsy. After orbitotomy and evacuation of the hematoma, the patient's visual acuity and motility returned to normal. In conclusion, chronic myelogenous leukemia should be considered in the differential diagnosis of nontraumatic subperiosteal orbital hematoma.

AB Reduction of intraocular pressure (IOP) is still the primary goal of glaucoma treatment. The aim of this prospective study was to examine the IOP lowering effect of selective laser trabeculoplasty (SLT) in patients on maximum tolerated medical therapy (MTMT), especially with regard to a potential influence of pseudophakia and topical prostaglandin analogues (PGA) on IOP reduction.
A total of 30 patients with a diagnosis of primary open angle glaucoma, normal tension glaucoma and pseudoexfoliative glaucoma with uncontrolled IOP despite MTMT underwent SLT treatment circumferentially over 360A degrees. Follow-up visits were conducted 1 day after SLT and then 1, 3, 6, 9, and 12 months post-treatment. The initial medication was continued unchanged for 3 months.
Median follow-up was 11.97 +/- 3.1 months, mean IOP at baseline was 19.60 +/- 4.69 mmHg, mean IOP reduction was -19.95 +/- 17.14% 1 month after and -14.07 +/- 23.57% 12 months after SLT (p < 0.001 and p = 0.003, respectively). Patients with higher baseline IOP had greater reduction of IOP after SLT (R-2 = 0.482, p < 0.001). Phakic patients had a significantly greater IOP reduction compared to pseudophakic patients (-aEuro parts per thousand 4.55 +/- 4.45 mmHg and + 2.75 +/- 6.75 mmHg, respectively, p = 0.010). Patients without PGA had a statistically insignificant greater IOP reduction compared to patients with PGA (-aEuro parts per thousand 7.40 +/- 4.72 mmHg and -2.48 +/- 5.22 mmHg, respectively, p = 0.066) and four patients needed additional surgery to lower IOP.
Even in patients already on maximum IOP lowering medication, SLT has the potential to significantly reduce IOP up to 1 year after treatment. The IOP reduction is most pronounced in phakic eyes with high preoperative IOP.

AB Background: Intervertebral disc herniation, spinal stenosis, intervertebral disc degeneration without disc herniation, and post lumbar surgery syndrome are the most common diagnoses of chronic persistent low back and lower extremity symptoms, resulting in significant economic, societal, and health care impact. Epidural injections are one of the most commonly performed interventions in the United States in managing chronic low back pain. However the evidence is highly variable among different techniques utilized - namely interlaminar, caudal, and transforaminal - and for various conditions, namely - intervertebral disc herniation, spinal stenosis, and discogenic pain without disc herniation or radiculitis. Multiple systematic reviews conducted in the evaluation of the effectiveness of interlaminar epidural injections have been marred with controversy. Consequently, the debate continues with regards to the effectiveness, indications, and medical necessity of interlaminar epidural injections.
Study Design: A systematic review of lumbar interlaminar epidural injections with or without steroids.
Objective: To evaluate the effect of lumbar interlaminar epidural injections with or without steroids in managing various types of chronic low back and lower extremity pain emanating as a result of disc herniation or radiculitis, spinal stenosis, and chronic discogenic pain.
Methods: The available literature on lumbar interlaminar epidural injections with or without steroids in managing various types of chronic low back pain with or without lower extremity pain was reviewed. The quality assessment and clinical relevance criteria utilized were the Cochrane Musculoskeletal Review Group criteria as utilized for interventional techniques for randomized trials and the criteria developed by the Newcastle-Ottawa Scale criteria for observational studies.
The level of evidence was classified as good, fair, or limited based on the quality of evidence developed by the U. S. Preventive Services Task Force (USPSTF).
Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to December 2011, and manual searches of the bibliographies of known primary and review articles.
Outcome Measures: The primary outcome measure was pain relief (short-term relief = up to 6 months and long-term > 6 months). Secondary outcome measures were improvement in functional status, psychological status, return to work, and reduction in opioid intake.
Results: Overall, 82 lumbar interlaminar trials were identified. All non-randomized studies without fluoroscopy and randomized trials not meeting the inclusion criteria were excluded. Overall, 15 randomized trials and 11 non-randomized studies were included in the analysis. Analysis was derived mainly from fluoroscopically-guided randomized trials and non-randomized studies.
The evidence is good for radiculitis secondary to disc herniation with local anesthetics and steroids, fair with local anesthetic only; whereas it is fair for radiculitis secondary to spinal stenosis with local anesthetic and steroids, and fair for axial pain without disc herniation with local anesthetic with or without steroids, with fluoroscopically-guided epidural injections.
Limitations: The limitations of this study include that we were unable to perform meta-analysis for disc herniation, and the paucity of evidence for discogenic pain and spinal stenosis. Further, methodological criteria have been highly variable along with sample sizes. The studies were heterogenous.
Conclusion: The evidence based on this systematic review is good for lumbar epidural injections under fluoroscopy for radiculitis secondary to disc herniation with local anesthetic and steroids, fair with local anesthetic only; whereas it is fair for radiculitis secondary to spinal stenosis with local anesthetic and steroids, and fair for axial pain without disc herniation with local anesthetic with or without steroids.

AB Objectives: Disrupted skeletal homeostasis is common in patients with prostate cancer. Low bone density is common at diagnosis, and fracture risk is further elevated by the effects of androgen-deprivation therapy. Later in the disease course, bone metastases can result in skeletal morbidity. Although prostate-specific antigen (PSA) levels can provide important insights into overall disease progression, convenient, noninvasive tools for monitoring skeletal health are lacking. Biochemical markers released into serum and urine as a result of bone turnover might fulfill this unmet need. The objectives of this article are to assess current evidence examining the potential utility of bone turnover markers for monitoring skeletal health, bone disease progression, and response to antiresorptive therapies in the prostate cancer setting.
Methods: Published articles and abstracts from major oncology or urology congresses pertaining to the use of bone turnover markers to monitor skeletal health and disease progression were identified and assessed for relevance and methodologic stringency.
Results: Several randomized trials and correlative studies support the utility of bone marker level changes to assess disease progression in the metastatic setting, bone health during hormonal therapy, and response to bisphosphonate therapy. The available data support potential associations between levels of the collagen type I telopeptides (NTX and CTX) and the severity of metastatic bone disease as well as outcomes during antiresorptive therapy. Evidence linking bone marker level changes with early diagnosis of skeletal metastases is emerging. Although several markers have shown promising results in correlative studies, results from ongoing prospective trials are needed to establish the role of bone markers in this setting.
Conclusions: Bone marker levels reflect ongoing skeletal metabolism and can provide important insights into bone health and response to bisphosphonate therapy in patients with prostate cancer. The data supporting a role for bone markers to monitor skeletal disease progression and response to zoledronic acid therapy are especially strong. Bone marker assessments may complement established diagnostic and monitoring paradigms in prostate cancer. (C) 2012 Elsevier Inc. All rights reserved.

AB The changing healthcare environment will demand greater integration and coordination of care for patients. By incorporating systemic therapies into the practice of urologic oncology, our specialty has the opportunity to take the lead in this initiative. By learning how to deliver these therapies to patients in need, urologic oncologists likely will improve communication and trust, as patients often will already have a long and positive relationship with their urologist. In turn, this will likely lead to increased satisfaction with care and possibly improved outcomes. The development of comprehensive urologic oncology practices that include the administration of systemic therapy will maintain the relevance of the specialty and ultimately benefit our patients.

AB Introduction. Estrogen receptor (ER) status is not an optimal marker for response to adjuvant endocrine therapy since approximately 30% of patients with ER-positive tumors eventually relapse. Bcl-2 is regulated by ER and may thus be considered as an indicator of ER activity and a candidate supplementary marker to ER status. Patients and methods. Tumor tissue from 257 patients with ER-positive breast cancer treated with tamoxifen was used for determination of the best threshold for immunohistochemical Bcl-2 assessment as prognostic marker. Subsequently, samples from the Danish patients of the randomized clinical trial BIG 1-98 comprising 1191 ER-positive patients treated with tamoxifen, letrozole or a sequence of the two were immunohistochemically stained for Bcl-2 to further explore the prognostic value of Bcl-2. Results. Two Bcl-2 levels were found to divide the population of the primary study into significantly different groups according to disease-free survival (DFS). Multivariate analysis confirmed the significance of the lowest level, and showed Bcl-2 to be an independent prognostic marker. Analysis of the Danish cohort of the BIG 1-98 confirmed that Bcl-2 was a significant predictor of DFS, independent of known prognostic markers. However, in an additional analysis of a subset of the Danish cohort of BIG 1-98 including only HER-2 normal patients, the effect of Bcl-2 was not statistically significant. Discussion. Low Bcl-2 can predict poor outcome of patients with ER-positive tumors treated with adjuvant endocrine therapy, whereas the use of Bcl-2 for determination of addition of chemotherapy was not supported by this study.

Am J Physiol Heart Circ Physiol 303: H234-H240, 2012. First published May 18, 2012; doi:10.1152/ajpheart.00227.2012.-Cardiac interstitial fibrillar collagen accumulation, such as that associated with chronic pressure overload (PO), has been shown to impair left ventricular diastolic function. Therefore, insight into cellular mechanisms that mediate excessive collagen deposition in the myocardium is pivotal to this important area of research. Collagen is secreted as a soluble procollagen molecule with NH2- and COOH (C)-terminal propeptides. Cleavage of these propeptides is required for collagen incorporation to insoluble collagen fibrils. The C-procollagen proteinase, bone morphogenic protein 1, cleaves the C-propeptide of procollagen. Procollagen C-endopeptidase enhancer (PCOLCE) 2, an enhancer of bone morphogenic protein-1 activity in vitro, is expressed at high levels in the myocardium. However, whether the absence of PCOLCE2 affects collagen content at baseline or after PO induced by transverse aortic constriction (TAC) has never been examined. Accordingly, in vivo procollagen processing and deposition were examined in wild-type (WT) and PCOLCE2-null mice. No significant differences in collagen content or myocardial stiffness were detected in non-TAC (control) PCOLCE2-null versus WT mice. After TAC-induced PO, PCOLCE2-null hearts demonstrated a lesser collagen content (PCOLCE2-null TAC collagen volume fraction, 0.41% +/- 0.07 vs. WT TAC, 1.2% +/- 0.3) and lower muscle stiffness compared with WT PO hearts [PCOLCE2-null myocardial stiffness (beta), 0.041 +/- 0.002 vs. WT myocardial stiffness, 0.065 +/- 0.001]. In addition, in vitro, PCOLCE2-null cardiac fibroblasts exhibited reductions in efficiency of C-propeptide cleavage, as demonstrated by increases in procollagen alpha 1(I) and decreased levels of processed collagen alpha 1(I) versus WT cardiac fibroblasts. Hence, PCOLCE2 is required for efficient procollagen processing and deposition of fibrillar collagen in the PO myocardium. These results support a critical role for procollagen processing in the regulation of collagen deposition in the heart.

TI Detection and Diagnostic Value of Urine Leucine-Rich
alpha-2-Glycoprotein in Children With Suspected Acute Appendicitis
SO ANNALS OF EMERGENCY MEDICINE
LA English
DT Article
AB Study objective: Previously, we used a proteomics approach for the discovery of new diagnostic markers of acute appendicitis and identified leucine-rich alpha-2-glycoprotein (LRG) that was elevated in the urine of children with acute appendicitis and enriched in diseased appendices. Here, we sought to evaluate the diagnostic utility of enzyme-linked immunosorbent assay (ELISA) of urine LRG in a blinded, prospective, cohort study of children being evaluated for acute abdominal pain.
Methods: Urine LRG concentration was measured with a commercially available LRG ELISA and selected ion monitoring mass spectrometry. Urine LRG test performance was evaluated blindly against the pathologic diagnosis and histologic grade of appendicitis.
Results: Urine LRG was measured in 49 patients. Mean urine LRG concentration measured with commercial LRG ELISA was significantly elevated in patients with acute appendicitis but exhibited an interference effect. Direct measurements using selected ion monitoring mass spectrometry demonstrated that LRG was elevated more than 100-fold in patients with acute appendicitis compared with those without, with the receiver operating characteristic area under the curve of 0.98 (95% confidence interval 0.96 to 1.0). Among patients with acute appendicitis, elevations of urine LRG measured with ELISA and selected ion monitoring mass spectrometry correlated with the histologic severity of appendicitis.
Conclusion: Urine LRG ELISA allows for discrimination between patients with and without acute appendicitis but exhibits limited accuracy because of immunoassay interference. Direct measurements of urine LRG with selected ion monitoring mass spectrometry demonstrate superior diagnostic performance. Development of a clinical-grade urine LRG assay is needed to advance the diagnostic accuracy of clinical evaluations of appendicitis. [Ann Emerg Med. 2012;60:78-83.]

AB Capecitabine produces an objective response rate of up to 25 % in anthracycline-treated, taxane-resistant metastatic breast cancer (MBC). The farnesyltransferase inhibitor tipifarnib inhibits Ras signaling and has clinical activity when used alone in MBC. The objective of this study was to determine the efficacy and safety of tipifarnib-capecitabine combination in MBC patients who were previously treated with an anthracycline and progressed on taxane therapy. Eligible patients received oral capecitabine 1,000 mg/m(2) twice daily plus oral tipifarnib 300 mg twice daily on days 1-14 every 21 days. The primary endpoint was ORR. The trial was powered to detect an improvement in response rate from 25 to 40 %. Among 63 eligible, partial response occurred in six patients (9.5 %; 90 % CI 4.2-17.9 %), median progression-free survival was 2.6 months (95 % CI 2.1-4.4), and median overall survival was 11.4 months (95 % CI 7.7-14.0). Dose modifications were required for 43 patients (68 %) for either tipifarnib and/or capecitabine. Grades 3 and 4 toxicities were seen in 30 patients (44 %; 90 % CI 44.4-67.0 %) and 11 patients (16 %; 90 % CI 10.8-29.0 %), respectively. The most common grade 3 toxicities included neutropenia, nausea, and vomiting; and the most common grade 4 toxicity was neutropenia (8 out of 11 cases). The tipifarnib-capecitabine combination is not more effective than capecitabine alone in MBC patients who were previously treated with an anthracycline and taxane therapy.

AB Unambiguous classification of BRCA1 and BRCA2 variants of uncertain significance (VUS) is a challenging task that vexes health care providers and has profound implications for patients and their family members. Numerous VUS have been described to date, which await assessment of their functional, hence clinical, impact. As a result of a routine BRCA1/BRCA2 mutational screening, we identified a previously unreported BRCA1 sequence alteration [c.5178G > A (V1687I)] in a patient diagnosed with early onset triple negative breast cancer. The sequence alteration falls in the invariant THV motif of the BRCT domain. To investigate its significance, we applied an integrated approach that, in addition to genetic and histopathological data, included in silico analyses, comparative structural modeling and verification of BRCT-mediated interactions. In line with web-based algorithms that predicted the benign nature of BRCA1 V1687I, the three-dimensional model of the BRCA1 V1687I BRCT domain did not reveal any major structural changes relative to its wild-type counterpart, thus suggesting that BRCA1 V1687I has a negligible impact on both the local architecture and the overall stability of the protein. Consistently, the BRCA1 V1687I protein was properly expressed and localized to the nucleus, and it was still capable of binding three BRCT-interacting, DNA damage response, and repair partner proteins, namely BRIP1/FANCJ, CtIP, and Abraxas. Our collected evidence suggests that, although occurring in a highly conserved region, the BRCA1 V1687I variant is likely a benign sequence alteration.

AB While increasing numbers of patients are seeking acupuncture treatment for depression in recent years, there is limited evidence of the antidepressant (AD) effectiveness of acupuncture. Given the unsatisfactory response rates of many Food and Drug Administration-approved ADs, research on acupuncture remains of potential value. Therefore, we sought to review the efficacy and safety of acupuncture treatment for depression in clinical applications. We conducted a PubMed search for publications through 2011. We assessed the adequacy of each report and abstracted information on reported effectiveness or efficacy of acupuncture as monotherapy for major depressive disorder (MDD) and as augmentation of ADs. We also examined adverse events associated with acupuncture, and evidence for acupuncture as a means of reducing side effects of ADs. Published data suggest that acupuncture, including manual-, electrical-, and laser-based, is a generally beneficial, well-tolerated, and safe monotherapy for depression. However, acupuncture augmentation in AD partial responders and nonresponders is not as well studied as monotherapy; and available studies have only investigated MDD, but not other depressive spectrum disorders. Manual acupuncture reduced side effects of ADs in MDD. We found no data on depressive recurrence rates after recovery with acupuncture treatment. Acupuncture is a potential effective monotherapy for depression, and a safe, well-tolerated augmentation in AD partial responders and nonresponders. However, the body of evidence based on well-designed studies is limited, and further investigation is called for.

AB Interest in nonpharmaceutical supplements for treating major depressive disorder (MDD) has increased significantly, both among patients and among clinicians during the past decades. Despite the large array of antidepressants (ADs) available, many patients continue to experience relatively modest response and remission rates, in addition to a burden of side effects that can hinder treatment compliance and acceptability. In this article, we review the literature on folates and S-adenosylmethionine (SAMe), 2 natural compounds linked in the 1-carbon cycle metabolic pathway, for which substantial evidence supports their involvement in mood disorders. Background information, efficacy data, proposed mechanisms of action, and side effects are reviewed.
Based on existing data, supplementation with SAMe, as well as with various formulations of folates, appears to be efficacious and well tolerated in reducing depressive symptoms. Compared with other forms of folates, 5-methyltetrahydrofolate (L-methylfolate or 5-MTHF) may represent a preferable treatment option for MDD given its greater bioavailability in patients with a genetic polymorphism, and the lower risk of specific side effects associated with folic acid.
Although further randomized controlled trials in this area appear warranted, SAMe and L-methylfolate may represent a useful addition to the AD armamentarium.

AB A 57-year-old-male presented for whole-body PET with CT for restaging of lung cancer. Besides revealing postradiation changes, we noticed an unusual pattern of FDG uptake in the myocardium, with prominent metabolic uptake involving 4 chambers of the heart. Later that day, the patient was referred to the emergency department for increased heart rate, but otherwise asymptomatic. CT angiography was performed, which showed scattered filling defects in bilateral pulmonary arteries consistent with pulmonary embolism. The finding of prominent FDG uptake involving all cardiac chambers in this patient is likely related to heart strain caused by acute pulmonary embolism.

AB Purpose
The lack of research concerning treatment for individuals with diabetes mellitus (DM) and comorbid eating disorders (ED) contributes to the gulf between the psychosocial needs of individuals with the two conditions and the treatment they receive. Empirical evidence has established that the prognosis of patients with this comorbid diagnosis (ED-DM) is poor in the absence of a specialized DM treatment specifically adapted to ED. In individuals with DM, comorbid ED is associated with numerous complications. Despite these interactions, current knowledge about the comorbid diagnosis is limited, and eating disorders in patients with diabetes often remain undiagnosed. This article presents standard procedures for assessment and optimal therapeutic interventions for patients with ED and DM.
Conclusion
In patients with diabetes, problematic eating behaviors and symptoms should be assessed routinely. When an eating disorder is detected, diabetes management needs to be adapted, binge eating or medication misuse needs to be addressed, and eating disorder specialists should be included in the multidisciplinary team.

AB Effective CD8+ T-cell responses against tumor or microbial antigens that are not directly expressed in antigen-presenting cells (APCs) depend on the cross-presentation of these antigens on MHC class I in APCs. To identify signaling molecules that regulate cross-presentation, we used lentiviral-based RNA interference to test the roles of hundreds of kinases and phosphatases in this process. Our study uncovered eight previously unknown genes, consisting of one positive and seven negative regulators of antigen cross-presentation. Depletion of Acvr1c, a type I receptor for TGF-beta family of signaling molecules, led to an increase in CD80 and CD86 co-stimulator surface expression and secreted IL-12 in mouse bone marrow-derived DCs, as well as antigen-specific T-cell proliferation.

AB Characterization of the human antibody (Ab) repertoire in mouse models of the human immune system is essential to establish their relevance in translational studies. Single human B cells were sorted from bone marrow and periphery of humanized NOD/SCID gamma c(null) (hNSG) mice at 8-10 months post engraftment with human cord blood-derived CD34(+) stem cells. Human IG variable heavy (V-H) and kappa (V-kappa) genes were amplified, cognate V-H-V-kappa gene-pairs assembled as single-chain variable fragment-Fc Abs (scFvFcs) and functional studies were performed. Although overall distribution of V-H genes approximated the normal human Ab repertoire, analysis of the V-H-third complementarity-determining regions in the mature B-cell subset demonstrated an increase in length and positive charges, suggesting autoimmune characteristics. Additionally, >70% of V-kappa sequences utilized V(kappa)4-1, a germline gene associated with autoimmunity. The mature B-cell subset-derived scFvFcs displayed the highest frequency of autoreactivity and polyspecificity, suggesting defects in checkpoint control mechanisms. Furthermore, these scFvFcs demonstrated binding to recombinant HIV envelope corroborating previous observations of poly/autoreactivity in anti-HIVgp140 Abs. These data lend support to the hypothesis that anti-HIV broadly neutralizing antibodies may be derived from auto/polyspecific Abs that escaped immune elimination and that the hNSG mouse could provide a new experimental platform for studying the origin of anti-HIV-neutralizing Ab responses.

AB Aim: Errors are most likely to occur during the pre- and postanalytic phases of the genetic testing process, which can contribute to underuse, overuse, and misuse of genetic tests. To mitigate these errors, we created a template for molecular genetic test reports that utilizes the combined features of synoptic reporting and narrative interpretation. Methods: A variation of the Delphi consensus process with an expert panel was used to create a draft report template, which was further informed by focus group discussions with primary care physicians. Results: There was agreement that molecular genetic test reports should present information in groupings that flow in a logical manner, and most participants preferred the following order of presentation: patient and physician information, test performed, test results and interpretation, guidance on next steps, and supplemental information. We define data elements for the report as "required," "optional," "possible," and "not necessary"; provide recommendations regarding the grouping of these data elements; and describe the ideal design of the report template, including the preferred order of the report sections, formatting of data, and length of the report. Discussion: With input from key stakeholders and building upon prior work, we created a template for molecular genetic test reports designed to improve clinical decision making at the point of care. The template design should lead to more effective communication between the laboratory and ordering clinician. Studies are needed to assess the usefulness and effectiveness of molecular genetic test reports generated using this template.

ID CYST PSEUDOENHANCEMENT; IMAGE SUBTRACTION; CELL CARCINOMA; PHANTOM
AB Purpose: To evaluate the impact of subtraction CT on reader confidence and diagnostic accuracy when characterizing renal masses.
Materials and Methods: In this institutional review board-approved retrospective study, 159 patients (85 men and 74 women; mean age, 62.6 years; range, 22-88 years) underwent routine unenhanced and contrast-enhanced multidetector computed tomography (MDCT) for renal lesion characterization. Subtraction images were subsequently generated on scanner console. Two readers independently reviewed the MDCT images to characterize presence of enhancement using a 6-point scale during 3 blinded review sessions of (1) only subtraction, (2) routine, and (3) combined subtraction and routine images. The standard of reference consisted of either histopathology or follow-up imaging and clinical data.
Results: Of the 240 lesions evaluated, 60 lesions (mean, 3.2 cm; range, 1-7.5 cm) were enhancing and 180 lesions (mean, 2.7 cm; range, 0.5-12 cm) were nonenhancing. For determination of lesion enhancement, a combined evaluation of routine MDCT and subtraction images improved reader confidence in 60% to 63% of lesions (P < 0.001). The combined evaluation also provided the highest sensitivity (97%), specificity (99%), and accuracy (98.9%).
Conclusion: When used in combination with routine image interpretation, subtraction CT improves reader confidence and diagnostic accuracy in identifying enhancement in renal lesions.

AB Background: We employ the term postdeployment syndrome (PDS) to characterize the combinations of physical, psychological, and social difficulties frequently encountered by Veterans returning from combat. Objectives: To conduct a scoping review to identify and describe one-to-one peer mentorship (PM) interventions, identify elements associated with positive outcome and of relevance to Veterans with PDS, and summarize current practice in a way that informs the development of such interventions for this population. Methods: Scoping review methodology was used to identify and summarize key practices and concepts in the one-to-one PM literature between 1980 and 2012. Of 196 articles initially identified, 33 were retained for further examination. Eighteen met full-study criteria and were retained in the analyses. Three reviewers reached consensus on articles to include, and 2 coders independently extracted information from each article. Results: A range of populations was targeted in the interventions. Most identified the provision of support as the primary goal, although some also included other educational and behavioral goals. Most employed selection and training strategies for their mentors and offered ongoing supervision and consultation. Most studies indicated that participants found PM to be beneficial. Conclusions: This review supports the application in this population and proposes next steps for the development and systematic evaluation of PM interventions.

AB Biliary tract cancers (BTCs) are a heterogeneous group of malignancies, with a historically poor prognosis as a whole. Until recently, the development of effective therapeutics was hampered by the relatively low incidence, heterogeneity in patients and tumors, and correspondingly poor clinical trial enrollments. With the publication of the landmark phase III ABC-02 trial demonstrating the superiority of gemcitabine and cisplatin combination chemotherapy, the landscape changed for the development of new agents. Despite this progress, there are currently no approved targeted agents for BTC. This review will focus on recent developments in targeted therapeutics, directed against several key signaling pathways in BTC, including epidermal growth factor receptor, angiogenesis, and the mitogen-activated protein kinase pathway. Data from recent phase I and II trials will be discussed, along with a preview of upcoming trials involving targeted therapies.

AB Background: There is little information about the microbiologic profiles of periodontal lesions in Papillon-Lefevre syndrome (PLS) and the significance of bacteria in the pathogenesis of periodontitis in these patients. This comprehensive analysis of the subgingival microbiota in patients with PLS used 16S ribosomal RNA (rRNA) clonal analysis and the 16S rRNA-based Human Oral Microbe Identification Microarray (HOMIM).
Methods. Thirteen patients with PLS from seven unrelated families volunteered for this microbiologic study. Subgingival plaque was collected with sterile paper points from multiple sites with >= 5 mm probing depth, and whole genomic DNA was extracted. The 16S rRNA genes were amplified, cloned, and sequenced. The samples were then probed for approximate to 300 predominant oral bacterial species using the HOMIM.
Results: The most commonly detected phylotypes in the clonal analysis were Gemella morbillorum, Gemella haemolysans, Granulicatella adiacens, Lachnospiraceae OT 100 (EI074), Parvimonas micra, Selenomonas noxia, and Veillonella parvula. As a group, streptococci were commonly detected in these individuals. In the HOMIM analysis, a total of 170 bacterial species/phylotypes were detected, with a range of 40 to 80 species per patient with PLS. Of these, 12 bacterial species were detected in medium to high levels in >= 50% of the individuals. The high-frequency strains were clustered into eight groups: Aggregatibacter actinomycetemcomitans, Campylobacter spp., Capnocytophaga granulosa, G. morbillorum, P. micra, Porphyromonas endodontalis, Streptococcus spp., and Tannerella forsythia.
Conclusions: The subgingival microbiota in PLS is diverse. Periodontal pathogens commonly associated with chronic and aggressive periodontitis and opportunistic pathogens may be associated with the development of severe periodontitis in patients with PLS. J Periodontol 2012;83:902-908.

AB A large amount of brain-derived neurotrophic factor (BDNF) is stored in the human platelets and only small amounts of it circulate in the plasma. However, a few studies have focused on platelet BDNF in patients with major depressive disorder (MDD) and childhood trauma. Our study population consisted of 105 MDD patients and 50 healthy controls. We used the Mini-International Neuropsychiatric Interview (M.I.N.I), the Early Trauma Inventory Self Report-Short Form (ETISR-SF), as well as measured serum, plasma, and platelet BDNF at baseline, 1 month, and 3 month periods. There was a significant association between childhood trauma and platelet BDNF at baseline, 1 month, and 3 months, after adjusting for age, gender, education, body mass index, severity of depression, anxiety, alcohol consumption, and current stress. Conversely, plasma and serum BDNF did not have a significant association with childhood trauma. MDD patients revealed significantly higher levels of platelet BDNF in those with childhood trauma than in those without (t = 2.4, p = 0.018), and platelet BDNF was significantly higher in cases with sexual abuse on post-hoc analysis (p = 0.042). However, no significant differences were found in healthy controls, according to whether or not they had experienced childhood trauma. Platelet BDNF showed a significant correlation with severity of childhood trauma at baseline (r = 0.25, p = 0.012) and at 3 months (r = 0.38, p = 0.003) in MOD. In conclusion, platelet BDNF was significantly higher in MDD patients with childhood trauma than in those without, and it was correlated with severity of trauma. (C) 2012 Elsevier Ltd.

AB Background: Dysfunction of glutamate neurotransmission has been implicated in the pathology of schizophrenia and bipolar disorder, and one mechanism by which glutamate signalling can be altered is through RNA editing of ionotropic glutamate receptors (iGluRs). The objectives of the present study were to evaluate the editing status of iGluRs in the human prefrontal cortex, determine whether iGluR editing is associated with psychiatric disease or suicide and evaluate a potential association between editing and alternative splicing in the a-amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA) iGluR subunits' pre-mRNA. Methods: We studied specimens derived from patients with antemortem diagnoses of bipolar disorder (n = 31) or schizophrenia (n = 34) who died by suicide or other causes, and from psychiatrically healthy controls (n = 34) who died from causes other than suicide. The RNA editing at all 8 editing sites within AMPA (GluA2-4 subunits) and kainate (GluK1-2 subunits) iGluRs was analyzed using a novel real-time quantitative polymerase chain reaction assay. Results: No differences in editing were detected among schizophrenia, bipolar or control groups or between suicide completers and patients who died from causes other than suicide. The editing efficiency was significantly higher in the flop than in the flip splicoforms of GluA3-4 AMPA subunits (all p < 0.001). Limitations: The study is limited by the near absence of specimens from medicationnaive psychiatric patients and considerable variation in medication regimens among individuals, both of which introduce considerable uncertainty into the analysis of potential medication effects. Conclusion: We found that iGluR RNA editing status was not associated with bipolar disorder, schizophrenia or suicide. Differences in editing between flip and flop splicoforms suggest that glutamate sensitivity of receptors containing GluA3 and/or GluA4 flop subunits is moderated as a result of increased editing.

DIAGNOSIS
AB OBJECTIVE: To assess the influence of hydatidiform mole (HM) management setting (reference center versus other institutions) on gestational trophoblastic neoplasia (GTN) outcomes.
METHODS: This cohort study included 270 HM patients attending Botucatu Trophoblastic Diseases Center (BTDC, Sao Paulo State University, Brazil) between January 1.990 and December 2009 (204 undergoing evacuation and entire postmolar follow-up at BTDC and 66 from other institutions [OIs]). GTN characteristics and outcomes were analyzed and compared according to HM management setting. The confounding variables assessed included age, gravidity, parity, number of abortions and HM type (complete or partial). Postmolar GTN outcomes were compared using Mann-Whitney's test, chi(2) test or Fisher's exact test.
RESULTS: Postmolar GTN occurred in 34 (34/204= 16.7%) BTDC patients and in 27 (27/66=40.9%) of those initially treated in other institutions. BTDC patients showed lower metastasis rate (5.8% vs. 48%, p = 0.003) and lower median FIGO (2002) score (2.00 0.00, 3.001 vs. 4.00 [2.00, 7.00], p = 0.003]. Multiagent chemotherapy to treat postmolar GTN was required in 2 BTDC cases (5.9%) and in 8 OI cases (29.6%) (p = 0.017). Median time interval between molar evacuation and chemotherapy onset was shorter among BTDC patients (7.0 [6.0, 10.0] vs. 10.0[7.0, 16.0], p = 0.040).
CONCLUSION: BTDC patients showed GTN characteristics indicative of better prognosis. This underscores the importance of GTD specialist centers. (J Reprod Med 2012;57:305-309)

AB Many patients with PD develop PD with dementia (PDD), a syndrome that overlaps clinically and pathologically with dementia with Lewy bodies (DLB); PDD and DLB differ chiefly in the relative timing of dementia and parkinsonism. Brain amyloid deposition is an early feature of DLB and may account, in part, for its early dementia. We sought to confirm this hypothesis and also to determine whether amyloid accumulation contributes to cognitive impairment and dementia in the broad range of parkinsonian diseases. Twenty-nine cognitively healthy PD, 14 PD subjects with mild cognitive impairment (PD-MCI), 18 with DLB, 12 with PDD, and 85 healthy control subjects (HCS) underwent standardized neurologic and neuropsychological examinations and Pittsburgh compound B (PiB) imaging with PET. Apolipoprotein E (ApoE) genotypes were obtained in many patients. PiB retention was expressed as the distribution volume ratio using a cerebellar tissue reference. PiB retention was significantly higher in DLB than in any of the other diagnostic groups. PiB retention did not differ across PDD, PD-MCI, PD, and HCS. Amyloid burden increased with age and with the presence of the ApoE e4 allele in all patient groups. Only in the DLB group was amyloid deposition associated with impaired cognition. DLB subjects have higher amyloid burden than subjects with PDD, PD-MCI, PD, or HCS; amyloid deposits are linked to cognitive impairment only in DLB. Early amyloid deposits in DLB relative to PDD may account for their difference in the timing of dementia and parkinsonism. (c) 2012 Movement Disorder Society

AB Addictive behaviors, such as cigarette smoking and coffee drinking, have been associated with a reduced risk of Parkinson's disease (PD). Whether alcohol consumption is also associated with PD risk is less certain. We prospectively followed 132,403 participants in the Cancer Prevention Study II Nutrition Cohort from 1992 to 2005. Alcohol intake was assessed at baseline. Incident cases of PD (n = 605; 389 male and 216 female) were confirmed by treating physicians and medical record review. Relative risks (RRs) were estimated using proportional hazards models, adjusting for age, smoking, and other risk factors. Alcohol consumption was not significantly associated with PD risk. After adjustment for age, smoking, and other risk factors, the RR comparing men consuming 30 or more grams of alcohol per day (highest category) to nondrinker men was 1.29 (95% confidence interval [CI]: 0.90, 1.86; P trend: 0.40), and the RR comparing women consuming 15 or more grams of alcohol (highest category) per day to nondrinker women was 0.77 (95% CI: 0.41, 1.45; P trend: 0.87). Consumption of beer, wine, or liquor was also not associated with PD risk. The results of this large, prospective study do not support an association between alcohol intake and risk of PD.

AB Background: Current thrombolytic therapies utilize exogenous plasminogen activators (PAs) to effectively lyse clots, restoring blood flow, and preventing tissue and organ death. These PAs may also impair normal hemostasis, leading to life-threatening bleeding, including intracerebral hemorrhage. Aims: This study aims to develop new thrombus-targeted fibrinolytic agents that harness the multifunctional theranostic capabilities of nanomaterials, potentially allowing for the generation of efficacious thrombolytics while minimizing deleterious side effects. Materials & methods: A thrombus-targeted nano-fibrinolytic agent was synthesized using a magnetofluorescent crosslinked dextran-coated iron oxide nanoparticle platform that was conjugated to recombinant tissue PA (tPA). Thrombus-targeting was achieved by derivatizing the nanoparticle with an activated factor XIII (FXIIIa)-sensitive peptide. Human plasma clot binding ability of the targeted and control agents was assessed by fluorescence reflectance imaging. Next, the in vitro enzymatic activity of the agents was assessed by S2288-based amidolytic activity, and an ELISA D-dimer assay for fibrinolysis. In vivo targeting of the nanoagent was next examined by intravital fluorescence microscopy of murine arterial and venous thrombosis. The fibrinolytic activity of the targeted nanoagent compared to free tPA was then evaluated in vivo in murine pulmonary embolism. Results: In vitro, the targeted thrombolytic nanoagent demonstrated superior binding to fresh-frozen plasma clots compared to control nanoagents (analysis of variance, p < 0.05). When normalized by S2288-based amidolytic activity, targeted, control and free tPA samples demonstrated equivalent in vitro fibrinolytic activity against human plasma clots, as determined by ELISA D-dimer assays. The FXIIIa targeted fibrinolytic nanoagent efficiently bound the margin of intravascular thrombi as detected by intravital fluorescence microscopy. In in vivo fibrinolysis studies the FXII la-targeted agent lysed pulmonary emboli with similar efficacy as free tPA (p > 0.05). Conclusion: The applicability of a FXIIIa-targeted thrombolytic nanoagent in the treatment of thromboembolism was demonstrated in vitro and in vivo. Future studies are planned to investigate the safety profile and overall efficacy of this class of nanoagents.

AB Activating mutations in the RAS family or BRAF frequently occur in many types of human cancers but are rarely detected in breast tumors. However, activation of the RAS-RAF-MEK-ERK MAPK pathway is commonly observed in human breast cancers, suggesting that other genetic alterations lead to activation of this signaling pathway. To identify breast cancer oncogenes that activate the MAPK pathway, we screened a library of human kinases for their ability to induce anchorage-independent growth in a derivative of immortalized human mammary epithelial cells (HMLE). We identified p21-activated kinase 1 (PAK1) as a kinase that permitted HMLE cells to form anchorage-independent colonies. PAK1 is amplified in several human cancer types, including 30-33% of breast tumor samples and cancer cell lines. The kinase activity of PAK1 is necessary for PAK1-induced transformation. Moreover, we show that PAK1 simultaneously activates MAPK and MET signaling; the latter via inhibition of merlin. Disruption of these activities inhibits PAK1-driven anchorage-independent growth. These observations establish PAK1 amplification as an alternative mechanism for MAPK activation in human breast cancer and credential PAK1 as a breast cancer oncogene that coordinately regulates multiple signaling pathways, the cooperation of which leads to malignant transformation.

AB Breast cancer brain metastases (BCBMs) are the second most frequent secondary central nervous system metastases following those associated with non-small-cell lung cancer. It is increasingly evident that BCBM arises as a function of the biology of the primary tumor and the metastatic niche, which combine to create a unique microenvironment in the brain impacting both metastatic colonization and therapeutic response. Clinical outcomes are improving for BCBM patients as a result of modern combinatorial therapies, challenging the traditionally nihilistic approach to this patient subgroup. This review will focus on the breast cancer subtypes with the highest incidence of BCBM-human epidermal growth factor receptor 2 (HER2)-positive breast cancer, and triple-negative (estrogen receptor [ER]-negative, progesterone receptor [PR]-negative, and HER2-negative) breast cancer (TNBC)-and Will characterize differences in the clinical behavior of brain metastases that arise from these different subtypes. We will also highlight some of the recent preclinical studies that may shed light on the biological mechanisms and mediators underlying brain metastases. Finally, we will review published and current prospective trials of systemic therapies specifically for BCBM, including novel pathway-specific therapies.

AB Background: A woman from Italy presented with dystonic leg symptoms at the age of 59. Rapid-onset dystonia-parkinsonism (RDP) was not suspected until 3 affected children (2 male, 1 female) with presentations consistent with the disorder were recognized.
Methods: The mother and four of her children (3 with and 1 without dystonia) were evaluated with an extensive battery including standardized history questionnaire and rating scales. In addition, all four children had cognitive testing and three of the four children had psychiatric interviews.
Results: In this family, a T613M mutation in the ATP1A3 gene was confirmed, the most common mutation present in patients with RDP. The proband's limb dystonia was atypical of RDP, symptoms of the others affected included dysarthria, asymmetric limb dystonia, and dysphagia more consistent with RDP. The two sons developed dystonia-parkinsonism in adolescence after consuming large amounts of alcohol. All 3 of those with psychiatric interviews reached diagnosable thresholds for mood disorder (bipolar or dysthymia) and some form of anxiety disorder.
Conclusions: The phenotype and age of onset is broader than previously reported in RDP, suggesting that it could be under-reported. Prior to this study, neuropsychologic symptoms associated with RDP were under-appreciated. Those patients who are at risk or suspected of having RDP should be cautioned to avoid excessive alcohol intake. Further study is needed to assess if the cognitive and psychiatric features are part of a broader RDP phenotype and this may have implications for future research into genetic susceptibility for psychiatric disease.

AB Objective: Explore the validity of using patient reports to measure shared decision making (SDM).
Methods: 178 patients diagnosed with breast cancer obtained SDM assistance in a university-based clinic. Trained observers rated physician SDM behaviors and surveyed patients. We calculated the frequency with which patients and observers reported maximum SDM behaviors for each survey item. We also calculated agreement frequency between patients and observers.
Results: Over 90% of patients rated doctors as reflecting SDM competencies. Patients reported doctors making recommendations more than soliciting their preferred choice (90% vs. 69%, p < 0.001). Patients heard benefits discussed "a lot" more often than they heard risks and side effects discussed "a lot" (81% vs. 58%, p < 0.001). Agreement between patients and observers was 75%. In cases of disagreement, patients more frequently perceived SDM behaviors than did observers (15% vs. 9%, p = 0.002), suggesting a possible agreement bias.
Conclusions: High agreement supports further investigation into using patients as efficient and effective raters of SDM. Patient ratings may be inflated by agreement bias. Practice implications: Doctors presentations may be biased toward discussing benefits more than risks. Policy makers can solicit patient ratings of SDM as long as they are aware of possibly inflated ratings due to agreement bias. (C) 2012 Published by Elsevier Ireland Ltd.

Physiol Rev 92: 1087-1187, 2012; doi:10.1152/physrev.00032.2011.-This review summarizes the brain mechanisms controlling sleep and wakefulness. Wakefulness promoting systems cause low-voltage, fast activity in the electroencephalogram (EEG). Multiple interacting neurotransmitter systems in the brain stem, hypothalamus, and basal forebrain converge onto common effector systems in the thalamus and cortex. Sleep results from the inhibition of wake-promoting systems by homeostatic sleep factors such as adenosine and nitric oxide and GABAergic neurons in the preoptic area of the hypothalamus, resulting in large-amplitude, slow EEG oscillations. Local, activity-dependent factors modulate the amplitude and frequency of cortical slow oscillations. Non-rapid-eye-movement (NREM) sleep results in conservation of brain energy and facilitates memory consolidation through the modulation of synaptic weights. Rapid-eye-movement (REM) sleep results from the interaction of brain stem cholinergic, aminergic, and GABAergic neurons which control the activity of glutamatergic reticular formation neurons leading to REM sleep phenomena such as muscle atonia, REMs, dreaming, and cortical activation. Strong activation of limbic regions during REM sleep suggests a role in regulation of emotion. Genetic studies suggest that brain mechanisms controlling waking and NREM sleep are strongly conserved throughout evolution, underscoring their enormous importance for brain function. Sleep disruption interferes with the normal restorative functions of NREM and REM sleep, resulting in disruptions of breathing and cardiovascular function, changes in emotional reactivity, and cognitive impairments in attention, memory, and decision making.

Physiol Rev 92: 1479-1514, 2012; doi:10.1152/physrev.00022.2011.-The sirtuins are a family of highly conserved NAD(+)-dependent deacetylases that act as cellular sensors to detect energy availability and modulate metabolic processes. Two sirtuins that are central to the control of metabolic processes are mammalian sirtuin 1 (SIRT1) and sirtuin 3 (SIRT3), which are localized to the nucleus and mitochondria, respectively. Both are activated by high NAD(+) levels, a condition caused by low cellular energy status. By deacetylating a variety of proteins that induce catabolic processes while inhibiting anabolic processes, SIRT1 and SIRT3 coordinately increase cellular energy stores and ultimately maintain cellular energy homeostasis. Defects in the pathways controlled by SIRT1 and SIRT3 are known to result in various metabolic disorders. Consequently, activation of sirtuins by genetic or pharmacological means can elicit multiple metabolic benefits that protect mice from diet-induced obesity, type 2 diabetes, and nonalcoholic fatty liver disease.

AB It was the objective of this study to determine whether reduced cleavage of von Willebrand factor (VWF) multimers following aortic valve replacement (AVR) is a consequence of reduced shear stress or postoperative changes in VWF cleavage protease (ADAMTS-13) activity. Aortic stenosis (AS) may be complicated by acquired von Willebrand disease. Aortic valve replacement (AVR) corrects the associated haematologic abnormalities. We enrolled 114 patients with severe AS scheduled for either balloon aortic valvuloplasty (BAV; n=64) or AVR (n=50). Haematologic assessments of VWF levels and activity and ADAMTS-13 were performed before and 24 hours after valve intervention. The VWF:RCo to VWF:Ag ratio, a surrogate for large VWF multimer activity, increased by 37% (p < 0.0001) after AVR and by 10% (p = 0.0002) after BAV. ADAMTS-13 activity significantly decreased after AVR (579 +/- 127 to 468 +/- 135 ng/ml; p<0.0001), but not after BAV (484 153 to 529 185 ng/ml; p = 0.10). By multivariable analysis, the change in VWF:RCo ratio after AVR was more strongly associated with the fall in ADAMTS-13 than with reduction of valve gradient; whereas the change in gradient better predicted the rise in VWF:RCo after BAV. In conclusion, both BAV and AVR reverse the haematological abnormalities of the acquired von Willebrand syndrome of AS and ADAMTS-13 levels decrease after AVR. These findings suggest that a portion of the haematologic benefit of AVR may be due to a postoperative decline in ADAMTS-13 rather than solely to relief of AS as previously thought.

AB Background A major barrier to youth recovery is finding suitable sobriety-supportive social contexts. National studies reveal most adolescent addiction treatment programs link youths to community 12-step fellowships to help meet this challenge, but little is known empirically regarding the extent to which adolescents attend and benefit from 12-step meetings or whether they derive additional gains from active involvement in prescribed 12-step activities (e.g., contact with a sponsor and other fellowship members). Greater knowledge in this area would enhance the efficiency of clinical continuing care recommendations. Methods Adolescent outpatients (N = 127; M age 16.7; 75% male; 87% white) enrolled in a naturalistic study of treatment effectiveness were assessed at intake and 3, 6, and 12 months later using standardized assessments. Mixed-effects models, controlling for static and time-varying confounds, examined the concurrent and lagged effects of 12-step attendance and active involvement on abstinence over time. Results The proportion attending 12-step meetings was relatively low across follow-up (24 to 29%), but more frequent attendance was independently associated with greater abstinence in concurrent and, to a lesser extent, lagged models. An 8-item composite measure of 12-step involvement did not enhance outcomes over and above attendance, but separate components did; specifically, greater contact with a 12-step sponsor outside of meetings and more verbal participation during meetings. Conclusions The benefits of 12-step participation observed among adult samples extend to adolescent outpatients. Community 12-step fellowships appear to provide a useful sobriety-supportive social context for youths seeking recovery, but evidence-based youth-specific 12-step facilitation strategies are needed to enhance outpatient attendance rates.

AB The Alzheimer's Disease Neuroimaging Initiative (ADNI) was launched in 2003 to speed drug development by validating imaging and blood/cerebrospinal fluid biomarkers for Alzheimer's disease clinical treatment trials. ADNI is a naturalistic (nontreatment) multisite longitudinal study. A true public private partnership, the first phase of ADNI (ADNI 1) set a new standard for data sharing without embargo. In addition, it has been extended to 2017 by additional funding (North American-ADNI Grand Opportunities and ADNI 2) as well as multiple projects around the world, collectively known as Worldwide ADNI (WW-ADNI). The goal of WW-ADNI is to harmonize projects and results across different geographical sites and to encourage and harmonize data management and availability to investigators around the world. WW-ADNI projects are currently underway in North America, Europe, Japan, Australia, Korea, Taiwan, and Argentina, with a nascent program in China and a possible future program in Brazil.

DEFIBRILLATOR; MORBIDITY; ENALAPRIL; PROGRAM; TRIAL
AB Background In 2005, the American College of Cardiology/American Heart Association published performance measures to provide a standard of care for hospitalized patients with heart failure ( HF). Despite increasing compliance with these measures, hospital mortality and readmission rates remain stagnant. Whether compliance with HF performance measures improves patient outcomes at the hospital level is unclear.
Methods We evaluated compliance with HF performance measures at 3,655 US hospitals. Patients admitted with a diagnosis of HF in 2008 were identified using the US Department of Health and Human Services Hospital Compare database. Compliance with 4 specific performance measures was examined: evaluation of left ventricular systolic function, administration of angiotensin-converting enzyme inhibitor I or angiotensin-receptor blocker for left ventricular systolic dysfunction, offering smoking cessation advice and counseling, and providing discharge instructions. Thirty-day mortality and readmission rate were recorded.
Results Hospitals reporting greater compliance with the 4 performance measures had significantly lower 30-day mortality rates. However, these hospitals were also located in areas of higher socioeconomic status and treated higher volumes of patients with HF. After adjusting for socioeconomic and hospital factors, only evaluation of left ventricular systolic function was associated with lower 30-day mortality, and evaluation of left ventricular systolic function and smoking cessation counseling were associated with lower readmission rates.
Conclusions We found that socioeconomic factors and hospital volume were stronger predictors of mortality than compliance with HF performance measures. After adjusting for socioeconomic factors and hospital volume, only 1 of the 4 performance measures was associated with lower 30-day mortality and 2 were associated with lower readmissions.

AB OBJECTIVE. Novel drugs targeting molecular pathways involved in tumor development have revolutionized cancer treatment. Radiologists often focus on therapeutic response when evaluating cancer patients and may miss important signs of drug toxicity. This article familiarizes radiologists with the complications of molecular targeted agents in abdominal solid organs, enabling early identification and appropriate intervention and thus reducing patient morbidity and mortality.
CONCLUSION. Knowledge of the common abdominal toxicities-including hepatitis, cholecystitis, pancreatitis, fluid retention, and infection-is crucial for early diagnosis, which may spare patients devastating complications or the need for surgery.

AB OBJECTIVE. The purpose of this article is to provide an updated review of uterine sarcomas. The traditionally described neoplasms are reviewed as well as several recently characterized entities in terms of their imaging and clinical aspects. We attempt to provide a longitudinal imaging overview, from initial presentation to follow-up. Imaging features are also described of response to traditional therapeutic agents and newer targeted agents.
CONCLUSION. A greater understanding of the pathogenesis has improved our ability to image and treat uterine sarcomas, both at initial staging and on follow-up. Targeted therapy is assuming an increasingly important role in the management of these lesions. It is imperative for radiologists to be aware of response characteristics and potential complications of these agents as well as conventional chemotherapeutic agents.

AB OBJECTIVE. The purpose of this article is to discuss nephrogenic systemic fibrosis (NSF) in detail regarding its history, possible pathophysiology, clinical and pathologic presentations, diagnosis, and implications for the radiology community.
CONCLUSION. NSF is a potentially lethal disorder that occurs in patients with reduced kidney function. Current evidence suggests a strong association with gadolinium-based contrast agents-mostly used in MRI-in this patient group. This has urged the radiology community to emphasize careful screening for the presence of renal dysfunction among patients for whom gadolinium-enhanced MRI is contemplated. Appropriate selection of gadolinium-based contrast agent type, avoidance of nonstandard dosage, patient education, and informed consent have been recommended by authorities.

AB Jet propulsion fuel-8 (JP-8) is the primary jet fuel used by the US military, collectively consuming similar to 2.5 billion gallons annually. Previous reports suggest that JP-8 is potentially toxic to the immune, respiratory, and nervous systems. The objectives of this study were to evaluate inhalation exposure to JP-8 constituents among active duty United States Air Force (USAF) personnel while performing job-related tasks, identify significant predictors of inhalation exposure to JP-8, and evaluate the extent to which surrogate exposure classifications were predictive of measured JP-8 exposures.
Seventy-three full-time USAF personnel from three different air force bases were monitored during four consecutive workdays where personal air samples were collected and analyzed for benzene, ethylbenzene, toluene, xylenes, total hydrocarbons (THC), and naphthalene. The participants were categorized a priori into high- and low-exposure groups, based on their exposure to JP-8 during their typical workday. Additional JP-8 exposure categories included job title groups and self-reported exposure to JP-8. Linear mixed-effects models were used to evaluate predictors of personal air concentrations.
The concentrations of THC in air were significantly different between a priori exposure groups (2.6 mg m(-3) in high group versus 0.5 mg m(-3) in low, P < 0.0001), with similar differences observed for other analytes in air. Naphthalene was strongly correlated with THC (r = 0.82, P < 0.0001) and both were positively correlated with the relative humidity of the work environment. Exposures to THC and naphthalene varied significantly by job categories based on USAF specialty codes and were highest among personnel working in fuel distribution/maintenance, though self-reported exposure to JP-8 was an even stronger predictor of measured exposure in models that explained 72% (THC) and 67% (naphthalene) of between-worker variability. In fact, both self-report JP-8 exposure and a priori exposure groups explained more between-worker variability than job categories.
Personal exposure to JP-8 varied by job and was positively associated with the relative humidity. However, self-reported exposure to JP-8 was an even stronger predictor of measured exposure than job title categories, suggesting that self-reported JP-8 exposure is a valid surrogate metric of exposure when personal air measurements are not available.

AB Objectives: Minimizing collateral thermal damage during endoscopic laryngeal laser surgery remains a priority, and tissue cooling is one way to achieve this goal. Cooling systems utilizing compressed air have been shown to reduce the extent of thermal trauma on the vocal folds, but these units are not ideal for endoscopic applications because cooling is inefficient at the low airflows needed. We examined whether a novel vortex cooling device that generates cooled air at low flow rates would provide a cooling benefit beyond that which could be obtained by using room-temperature air for cooling tissue or by using no cooling during simulated laryngeal laser surgery.
Methods: A continuous-wave thulium laser was used to incise glottic tissue in 12 calf vocal folds. Cooling was achieved with a prototype vortex cooler (9 degrees C air output; flow rate, 3 L/min), and tissue temperature measurements were compared to those with room-air cooling and no cooling. Thermal damage was analyzed histologically by measuring the depth of lactate dehydrogenase inactivation surrounding the mucosal incision. The cooling conditions were tested during time-constant cuts (8 seconds) and depth-constant cuts (into the thyroarytenoid muscle).
Results: During time-constant cuts, comparison between vortex cooling and room-air cooling revealed that vortex cooling resulted in a thermal damage zone that was 14% smaller (519 versus 603 mu m; p < 0.05). During depth-constant cuts, vortex cooling created a thermal damage zone that was 32% smaller than that created with no cooling (p < 0.01) and 9% smaller than that created with room-air cooling (p < 0.01).
Conclusions: Vortex cooling reduces thermal damage more effectively than room-air cooling or no cooling during both time-constant and depth-constant thulium laser cuts.

AB Objective: To describe a highly quantitative facial function measuring tool that yields accurate, objective measures of facial position in significantly less time than existing methods.
Methods: Facial Assessment by Computer Evaluation (FACE) software was designed for facial analysis. Outputs report the static facial landmark positions and dynamic facial movements relevant in facial reanimation. Fifty individuals underwent facial movement analysis using Photoshop-based measurements and the new software; comparisons of agreement and efficiency were made. Comparisons were made between individuals with normal facial animation and patients with paralysis to gauge sensitivity to abnormal movements.
Results: Facial measurements were matched using FACE software and Photoshop-based measures at rest and during expressions. The automated assessments required significantly less time than Photoshop-based assessments. FACE measurements easily revealed differences between individuals with normal facial animation and patients with facial paralysis.
Conclusions: FACE software produces accurate measurements of facial landmarks and facial movements and is sensitive to paralysis. Given its efficiency, it serves as a useful tool in the clinical setting for zonal facial movement analysis in comprehensive facial nerve rehabilitation programs.

AB Objective: To determine whether mutations in different Bardet-Biedl syndrome (BBS) genes result in different ocular phenotypes.
Methods: Thirty-seven patients from 31 families were enrolled who met the clinical criteria for BBS and for whom a BBS mutation had been identified. Seventeen patients harbored mutations in BBS1, 10 in BBS10, and 10 in other genes (BBS2, BBS3, BBS5, BBS7, and BBS12). All the patients underwent ocular examination; 36 patients had computerized full-field electroretinograms (ERGs).
Results: Visual acuity was significantly better in BBS1 patients than in patients with other BBS mutations (P=.01), and a larger proportion of BBS1 patients had good (>= 20/50) visual acuity (P=.01). The ERG amplitudes were significantly higher in BBS1 patients than in patients with other BBS mutations in response to 0.5-Hz and 30-Hz flashes (P <.001 for both). All the BBS1 patients harbored at least 1 missense mutation compared with only 45% of patients with mutations in other BBS genes (P <.001); the rest harbored only null alleles. However, multivariate analysis demonstrated that visual acuity or ERG amplitude did not depend on the type of mutation present (missense or null) when controlling for BBS gene. Prevalences of bone spicule pigmentation and cataract were comparable in BBS subtypes.
Conclusions: Patients with BBS1 mutations had a milder phenotype than did patients with mutations in other BBS genes. Clinically, this manifested as significantly better visual acuity and larger ERG amplitudes.

TI Comparison of Hospital Performance in Trauma vs Emergency and Elective
General Surgery Implications for Acute Care Surgery Quality Improvement
SO ARCHIVES OF SURGERY
LA English
DT Article
ID SURGICAL CARE; RISK; MARKER
AB Hypotheses: As emergency general surgery (EMGS) and trauma care are increasingly being provided by the same personnel with overlapping resources, we postulated that the quality of care provided to EMGS and trauma patients would be similar. We also evaluated the relationship between trauma and elective general surgery (ELGS) care, believing that performance would be similar across these services as it reflects institutional culture.
Design: Retrospective cohort study comparing hospital performance in trauma and EMGS care and in trauma and ELGS care. Regression models for mortality and serious morbidity were constructed for trauma, EMGS, and ELGS hospitals contributing to both the National Trauma Data Bank (2007) and American College of Surgeons National Surgical Quality Improvement Program (2005-2008).
Setting: Forty - six hospitals.
Main Outcome Measures: Correlations of observed to expected ratios were examined. Outlier status (hospitals with CIs of observed to expected ratios excluding 1.0) was compared using weighted kappa.
Results: There was no significant relationship between trauma and EMGS mortality (r=-0.01, P=.94; kappa=-0.10, P=.61) or between trauma and ELGS mortality (r=0.23, P=.12; kappa=0.07, P=.62). There was no significant relationship between trauma and EMGS morbidity (r=0.21, P=.17; kappa=0.04, P=.63) or between trauma and ELGS morbidity (r=0.16, P=.30; kappa=0.11, P=.37). No hospitals were consistently low or high outliers across all 3 groups.
Conclusions: Trauma performance improvement programs are well established compared with those for EMGS. Although EMGS patients use similar structures and processes as trauma patients, there is a lack of correlation between the quality of care provided to trauma and EMGS patients; EMGS should be incorporated into trauma performance improvement programs.

AB Objective: To determine whether bariatric surgery is associated with reduced health care expenditures in a multisite cohort of predominantly older male patients with a substantial disease burden.
Design: Retrospective cohort study of bariatric surgery. Outpatient, inpatient, and overall health care expenditures within Department of Veterans Affairs (VA) medical centers were examined via generalized estimating equations in the propensity-matched cohorts.
Setting: Bariatric surgery programs in VA medical centers.
Participants: Eight hundred forty-seven veterans who were propensity matched to 847 nonsurgical control subjects from the same 12 VA medical centers.
Intervention: Bariatric surgical procedures.
Main Outcome Measure: Health expenditures through December 2006.
Results: Outpatient, inpatient, and total expenditures trended higher for bariatric surgical cases in the 3 years leading up to the procedure and then converged back to the lower expenditure levels of nonsurgical controls in the 3 years after the procedure.
Conclusions: Based on analyses of a cohort of predominantly older men, bariatric surgery does not appear to be associated with reduced health care expenditures 3 years after the procedure.

AB Context: There has been considerable concern recently in the scientific and lay media regarding the benefits vs. the risks of bisphosphonates for the treatment of osteoporosis. Risks include possible associations with osteonecrosis of the jaw (ONJ) and atypical femur fractures. In this perspective, we review the use of bisphosphonates for the treatment of osteoporosis, including an objective assessment of the risks vs. the benefits of these drugs.
Evidence Acquisition: Authors' knowledge of the field and results of focused literature searches are presented.
Evidence Synthesis: Bisphosphonates have proven efficacy in the prevention of bone loss and in the reduction of fractures in postmenopausal women and men with established osteoporosis. Although bisphosphonates, at doses used to treat osteoporosis, may be associated with an increased risk of ONJ and atypical femur fractures, many more fractures are prevented by the use of these drugs compared to the relatively low risk of these complications. Although oral bisphosphonates are associated with upper gastrointestinal side effects and iv bisphosphonates with acute phase reactions, the association of bisphosphonate use with esophageal cancer and atrial fibrillation is not well supported by current data.
Conclusions: Bisphosphonates have been proven to prevent fractures in patients with established osteoporosis or those who are at high risk of fracture. In contrast, the incidence of major complications associated with bisphosphonate use, such as ONJ and atypical femur fractures, is very low. (J Clin Endocrinol Metab 97: 2272-2282, 2012)

AB Context: We wanted to investigate vitamin D in low-risk prostate cancer.
Objectives: The objective of the study was to determine whether vitamin D-3 supplementation at 4000 IU/d for 1 yr is safe and would result in a decrease in serum levels of prostate-specific antigen (PSA) or in the rate of progression.
Design: In this open-label clinical trial (Investigational New Drug 77,839), subjects were followed up until repeat biopsy.
Setting: All subjects were enrolled through the Medical University of South Carolina and the Ralph H. Johnson Veterans Affairs Medical Center, both in Charleston, SC.
Patients and Other Participants: All subjects had a diagnosis of low-risk prostate cancer. Fifty-two subjects were enrolled in the study, 48 completed 1 yr of supplementation, and 44 could be analyzed for both safety and efficacy objectives.
Intervention: The intervention included vitamin D-3 soft gels (4000 IU).
Main Outcome Measures: Adverse events were monitored throughout the study. PSA serum levels were measured at entry and every 2 months for 1 yr. Biopsy procedures were performed before enrollment (for eligibility) and after 1 yr of supplementation.
Results: No adverse events associated with vitamin D-3 supplementation were observed. No significant changes in PSA levels were observed. However, 24 of 44 subjects (55%) showed a decrease in the number of positive cores or decrease in Gleason score; five subjects (11%) showed no change; 15 subjects (34%) showed an increase in the number of positive cores or Gleason score.
Conclusion: Patients with low-risk prostate cancer under active surveillance may benefit from vitamin D-3 supplementation at 4000 IU/d. (J Clin Endocrinol Metab 97: 2315-2324, 2012)

AB Context: Timing and cause of pregnancy loss differ between type 1 (T1DM) and type 2 diabetes mellitus (T2DM).
Objective: The objective of the study was to determine whether placental histology corresponds to differing causes of pregnancy loss in T1DM and T2DM. We hypothesized that placentas from mothers with T2DM would be more likely to demonstrate vascular pathology than those from mothers with T1DM.
Research Design/Setting/Participants: We reviewed medical histories, pregnancy outcomes, and placental histology of women with pregestational T1DM and T2DM with singleton pregnancies between 2001 and 2009 at a single tertiary care medical center.
Main Outcome Measures: Placental weight, placental dysmaturity, villous maturation, villitis of unclear etiology, and histological evidence of placental infarction were measured.
Results: Ninety-eight placentas were available for review, 53 from T1DM mothers (56%) and 45 from T2DM mothers (46%). Mean age and glycemic control each trimester did not differ between diabetes types. T2DM placentas had a higher prevalence of placental infarcts (22 vs. 6%, P = 0.02) and a lower prevalence of placental dysmaturity (12 vs. 29%, P = 0.05) compared with T1DM; rates differed from those reported in the general population. There was no difference in placental weight, villous maturity, or villitis of unclear etiology between diabetes types.
Conclusions: There were many similarities in placental histological findings between diabetes types. Still, one in five T2DM placentas displayed histological infarcts, consistent with a vascular, rather than glycemic, etiology of pregnancy complications, whereas T1DM placentas showed signs of abnormal development.

AB Objective: The relationships among skeletal muscle lipid peroxidation, intramyocellular lipid content (IMCL), and insulin sensitivity were evaluated in nine insulin-sensitive (IS), 13 insulin-resistant (IR), and 10 adults with type 2 diabetes (T2DM).
Design: Insulin sensitivity was assessed by hyperinsulinemic-euglycemic clamp [ glucose disposal rate (GDR)]. Lipid peroxidation was assessed by 4-hydroxynonenal (HNE)-protein adducts and general oxidative stress by protein carbonyl content. All patients were sedentary.
Results: Protein-HNE adducts were elevated 1.6-fold in T2DM compared with IS adults, whereas IR showed intermediate levels of HNE-modified proteins. Protein-HNE adducts correlated with GDR, waist circumference, and body mass index. IMCL was increased by 4.0- and 1.9-fold in T2DM and IR patients, respectively, compared with IS, and was correlated with GDR and waist circumference but not BMI. Protein carbonyls were not different among groups and did not correlate with any of the measured variables. Correlations were detected between IMCL and protein-HNE.
Conclusion: Our data show for the first time that skeletal muscle protein-HNE adducts are related to the severity of insulin resistance in sedentary adults. These results suggest that muscle lipid peroxidation could be involved in the development of insulin resistance. (J Clin Endocrinol Metab 97: E1182-E1186, 2012)

AB Context: A genome-wide association study has identified three loci (five independent signals) that confer risk for polycystic ovary syndrome (PCOS) in Han Chinese women. Replication is necessary to determine whether the same variants confer risk for PCOS in women of European ancestry.
Objective: The objective of the study was to test whether these PCOS risk variants in Han Chinese women confer risk for PCOS in women of European ancestry.
Design: This was a case-control study.
Setting: The study was conducted at deCODE Genetics in Iceland and two academic medical centers in the United States.
Patients: Cases were 376 Icelandic women and 565 and 203 women from Boston, MA, and Chicago, IL, respectively, all diagnosed with PCOS by the National Institutes of Health criteria. Controls were 16,947, 483, and 189 women not known to have PCOS from Iceland, Boston, and Chicago, respectively.
Intervention: There were no interventions.
Main Outcomes: Main outcomes were allele frequencies for seven variants in PCOS cases and controls.
Results: Two strongly correlated Han Chinese PCOS risk variants on chromosome 9q33.3, rs10986105[C], and rs10818854[A], were replicated in samples of European ancestry with odds ratio of 1.68 (P = 0.00033) and odds ratio of 1.53 (P = 0.0019), respectively. Other risk variants at 2p16.3 (rs13405728), 2p21 (rs12468394, rs12478601, and rs13429458), and 9q33.3 (rs2479106), or variants correlated with them, did not associate with PCOS. The same allele of rs10986105 that increased the risk of PCOS also increased the risk of hyperandrogenism in women without PCOS from Iceland and demonstrated a stronger risk for PCOS defined by the National Institutes of Health criteria than the Rotterdam criteria.
Conclusions: We replicated one of the five Chinese PCOS association signals, represented by rs10986105 and rs10818854 on 9q33, in individuals of European ancestry. Examination of the subjects meeting at least one of the Rotterdam criteria for PCOS suggests that the variant may be involved in the hyperandrogenism and possibly the irregular menses of PCOS.

AB Karmali F, Merfeld DM. A distributed, dynamic, parallel computational model: the role of noise in velocity storage. J Neurophysiol 108: 390-405, 2012. First published April 18, 2012; doi:10.1152/jn.00883.2011.-Networks of neurons perform complex calculations using distributed, parallel computation, including dynamic "real-time" calculations required for motion control. The brain must combine sensory signals to estimate the motion of body parts using imperfect information from noisy neurons. Models and experiments suggest that the brain sometimes optimally minimizes the influence of noise, although it remains unclear when and precisely how neurons perform such optimal computations. To investigate, we created a model of velocity storage based on a relatively new technique-"particle filtering"-that is both distributed and parallel. It extends existing observer and Kalman filter models of vestibular processing by simulating the observer model many times in parallel with noise added. During simulation, the variance of the particles defining the estimator state is used to compute the particle filter gain. We applied our model to estimate one-dimensional angular velocity during yaw rotation, which yielded estimates for the velocity storage time constant, afferent noise, and perceptual noise that matched experimental data. We also found that the velocity storage time constant was Bayesian optimal by comparing the estimate of our particle filter with the estimate of the Kalman filter, which is optimal. The particle filter demonstrated a reduced velocity storage time constant when afferent noise increased, which mimics what is known about aminoglycoside ablation of semicircular canal hair cells. This model helps bridge the gap between parallel distributed neural computation and systems-level behavioral responses like the vestibuloocular response and perception.

AB Maison SF, Usubuchi H, Vetter DE, Elgoyhen AB, Thomas SA, Liberman MC. Contralateral-noise effects on cochlear responses in anesthetized mice are dominated by feedback from an unknown pathway. J Neurophysiol 108: 491-500, 2012. First published April 18, 2012; doi:10.1152/jn.01050.2011.-Suppression of ipsilateral distortion product otoacoustic emissions (DPOAEs) by contralateral noise is used in humans and animals to assay the strength of sound-evoked negative feedback from the medial olivocochlear (MOC) efferent pathway. However, depending on species and anesthesia, contributions of other feedback systems to the middle or inner ear can cloud the interpretation. Here, contributions of MOC and middle-ear muscle reflexes, as well as autonomic feedback, to contra-noise suppression in anesthetized mice are dissected by selectively eliminating each pathway by surgical transection, pharmacological blockade, or targeted gene deletion. When ipsilateral DPOAEs were evoked by low-level primaries, contra-noise suppression was typically similar to 1 dB with contra-noise levels around 95 dB SPL, and it always disappeared upon contralateral cochlear destruction. Lack of middle-ear muscle contribution was suggested by persistence of contra-noise suppression after paralysis with curare, tensor tympani cauterization, or section of the facial nerve. Contribution of cochlear sympathetics was ruled out by studying mutant mice lacking adrenergic signaling (dopamine beta-hydroxylase knockouts). Surprisingly, contra-noise effects on low-level DPOAEs were also not diminished by eliminating the MOC system pharmacologically (strychnine), surgically, or by deletion of relevant cholinergic receptors (alpha 9/alpha 10). In contrast, when ipsilateral DPOAEs were evoked by high-level primaries, the contra-noise suppression, although comparable in magnitude, was largely eliminated by MOC blockade or section. Possible alternate pathways are discussed for the source of contra-noise-evoked effects at low ipsilateral levels.

AB Traumatic brain injury is a heterogeneous entity that encompasses both surgical and non-surgical conditions. Surgery may be indicated with traumatic lesions such as hemorrhage, fractures, or malignant cerebral edema. However, the neurological exam may be clouded by the effects of medications administered in the field, systemic injuries, and inaccuracies in hyperacute prognostication. Typically, neurological injury is considered irreversible if diffuse loss of grey/white matter differentiation or if brainstem hemorrhage (Duret hemorrhage) exists. We aim to characterize a cohort of patients undergoing bilateral hemicraniectomy for severe traumatic brain injury. A retrospective consecutive cohort of adult patients undergoing craniectomy for trauma was established between the dates of January 2008 and November 2011. The primary outcome of the study was in-hospital mortality. Secondary outcomes were ICU length of stay, surgical complications, and Glasgow Outcome Score at most recent follow-up. During the study period, 210 patients undergoing craniectomy for traumatic mass-occupying lesion (epidural hematoma, subdural hematoma, or parenchymal contusion) were analyzed. Of those, 9 met study criteria. In-hospital mortality was 67% (6 of 9 patients). The average ICU length of stay was 12 days. The GOS score was 3 in surviving patients. Bilateral hemicraniectomy is a heroic intervention for patients with severe TBI, but can be a life-saving procedure.

AB Genes functioning in folate-mediated 1-carbon metabolism are hypothesized to play a role in cardiovascular disease (CVD) risk beyond the current narrow focus on the MTHFR 677 C -> T (rs1801133) polymorphism. Using a cohort study design, we investigated whether sequence variants in the network of folate-related genes, particularly in genes encoding proteins related to SHMT1, predict CVD risk in 1131 men from the Normative Aging Study. A total of 330 single nucleotide polymorphisms (SNPs) in 52 genes, selected for function and gene coverage, were assayed on the Illumina GoldenGate platform. Age- and smoking-adjusted genotype-phenotype associations were estimated in regression models. Using a nominal P <= 5.00 x 10(-3) significance threshold, 8 SNPs were associated with CVD risk in single locus analyses. Using a false discovery rate (FDR) threshold (P-adjusted <= 1.00 x 10(-1)), a SNP in the GGH gene remained associated with reduced CVD risk, with a stronger association in early onset CVD cases (<55 y). A gene x folate interaction (MAT2B) and 2 gene x vitamin B-12 interactions (BHMT, SLC25A32) reached the FDR P-adjusted <= 2.00 x 10-1 threshold. Three biological hypotheses related to SHMT1 were explored and significant gene x gene interactions were identified for TYMS by UBE2N, FTH1 by CELF1, and TYMS by MTHFR. Variations in genes other than MTHFR and those directly involved in homocysteine metabolism are associated with CVD risk in non-Hispanic white males. This work supports a role for SHMT1-related genes and nuclear folate metabolism, including the thymidylate biosynthesis pathway, in mediating CVD risk. J. Nutr. 142: 1272-1279, 2012.

AB Tumor-derived mutant KRAS (v-Ki-ras-2 Kirsten rat sarcoma viral oncogene) oncoprotein is a critical driver of cancer phenotypes and a potential biomarker for many epithelial cancers. Targeted mass spectrometry analysis by multiple reaction monitoring (MRM) enables selective detection and quantitation of wild-type and mutant KRAS proteins in complex biological samples. A recently described immunoprecipitation approach (Proc. Nat. Acad. Sci. 2011, 108, 2444-2449) can be used to enrich KRAS for MRM analysis, but requires large protein inputs (2-4 mg). Here, we describe sodium dodecyl sulfate-polyacrylamide gel electrophoresis-based enrichment of KRAS in a low molecular weight (20-25 kDa) protein fraction prior to MRM analysis (GeLC-MRM). This approach reduces background proteome complexity, thus, allowing mutant KRAS to be reliably quantified in low protein inputs (5-50 mu g). GeLC-MRM detected KRAS mutant variants (G12D, G13D, G12V, G12S) in a panel of cancer cell lines. GeLC-MRM analysis of wild-type and mutant was linear with respect to protein input and showed low variability across process replicates (CV = 14%). Concomitant analysis of a peptide from the highly similar HRAS and NRAS proteins enabled correction of KRAS-targeted measurements for contributions from these other proteins. KRAS peptides were also quantified in fluid from benign pancreatic cysts and pancreatic cancers at concentrations from 0.08 to 1.1 fmol/mu g protein. GeLC-MRM provides a robust, sensitive approach to quantitation of mutant proteins in complex biological samples.

AB Objective. The ability of antiinflammatory strategies to alter cardiovascular risk has not been rigorously examined. Colchicine is an antiinflammatory agent that affects macrophages, neutrophils, and endothelial cells, all of which are implicated in the pathogenesis of cardiovascular disease. We examined whether colchicine use was associated with a reduced risk of myocardial infarction (MI) in patients with gout.
Methods. We conducted a retrospective, cross-sectional study of all patients with an International Classification of Diseases, 9th ed, code for gout in the electronic medical record (EMR) of the New York Harbor Healthcare System Veterans Affairs network and 1 hospital visit between August 2007 and August 2008. Hospital pharmacy data were used to identify patients who had filled at least 1 colchicine prescription versus those who had not. Demographics and CV comorbidities were collected by EMR review. The primary outcome was diagnosis of MI. Secondary outcomes included all-cause mortality and C-reactive protein (CRP) level.
Results. In total. 1288 gout patients were identified. Colchicine (n = 576) and no colchicine (n = 712) groups had similar baseline demographics and serum urate levels. Prevalence of MI was 1.2% in the colchicine versus 2.6% in the no-colchicine group (p = 0.03). Colchicine users also had fewer deaths and lower CRP levels, although these did not achieve statistical significance. Colchicine effects persisted when allopurinol users were excluded from the analysis.
Conclusion. In this hypothesis-generating study, gout patients who took colchicine had a significantly lower prevalence of MI and exhibited trends toward reduced all-cause mortality and lower CRP level versus those who did not take colchicine.

AB Objectives To examine the association between kidney function and all-cause mortality in octogenarians. Design Retrospective analysis of prospectively collected data. Setting Community. Participants Serum creatinine and cystatin C were measured in 1,053 Cardiovascular Health Study (CHS) All Stars participants. Measurements Estimated glomerular filtration rate (eGFR) was determined using the Chronic Kidney Disease Epidemiology Collaboration creatinine (eGFRCR) and cystatin C one-variable (eGFRCYS) equations. The association between quintiles of kidney function and all-cause mortality was analyzed using unadjusted and adjusted Cox proportional hazards models. Results Mean age of the participants was 85, 64% were female, 66% had hypertension, 14% had diabetes mellitus, and 39% had prevalent cardiovascular disease. There were 154 deaths over a median follow-up of 2.6 years. The association between eGFRCR and all-cause mortality was U-shaped. In comparison with the reference quintile (6475 mL/min per 1.73 m2), the highest (=75 mL/min per 1.73 m2) and lowest (=43 mL/min per 1.73 m2) quintiles of eGFRCR were independently associated with mortality (hazard ratio (HR) = 2.49, 95% confidence interval (CI) = 1.364.55; HR = 2.28, 95% CI = 1.264.10, respectively). The association between eGFRCYS and all-cause mortality was linear in those with eGFRCYS of less than 60 mL/min per 1.73 m2, and in the multivariate analyses, the lowest quintile of eGFRCYS (<52 mL/min per 1.73 m2) was significantly associated with mortality (HR = 2.04, 95% CI = 1.123.71) compared with the highest quintile (>0.88 mL/min per 1.73 m2). Conclusion Moderate reduction in kidney function is a risk factor for all-cause mortality in octogenarians. The association between eGFRCR and all-cause mortality differed from that observed with eGFRCYS; the relationship was U-shaped for eGFRCR, whereas the risk was primarily present in the lowest quintile for eGFRCYS.

AB Objectives To describe facility-level variation in two measures of potentially inappropriate prescribing prevalent in Veterans Affairs (VA) facilitiesexposure to high-risk medications in elderly adults (HRME) and drugdisease interactions (Rx-DIS)and to identify facility characteristics associated with high-quality prescribing. Design Cross-sectional. Setting VA Healthcare System. Participants Veterans aged 65 and older with at least one inpatient or outpatient visit in 20052006 (N = 2,023,477; HRME exposure) and a subsample with a history of falls or hip fractures, dementia, or chronic renal failure (n = 305,059; Rx-DIS exposure). Measurements Incident use of any HRME (iHRME) and incident Rx-DIS (iRx-DIS) and facility-level rates and facility-level predictors of iHRME and iRx-DIS exposure, adjusting for differences in patient characteristics. Results Overall, 94,692 (4.7%) veterans had iHRME exposure. At the facility level, iHRME exposure ranged from 1.6% at the lowest facility to 12.8% at the highest (median 4.7%). In the subsample, 9,803 (3.2%) veterans had iRx-DIS exposure, with a facility-level range from 1.3% to 5.8% (median 3.2%). In adjusted analyses, veterans seen in facilities with formal geriatric education had lower odds of iHRME (odds ratio (OR) = 0.86, 95% confidence interval (CI) = 0.770.96) and iRx-DIS (OR = 0.95, 95% CI = 0.881.01). Patients seen in facilities caring for fewer older veterans had greater odds of iHRME (OR = 1.54, 95% CI = 1.351.75) and iRx-DIS exposure (OR = 1.22, 95% CI = 1.111.33). Conclusion Substantial variation in the quality of prescribing for older adults exists across VA facilities, even after adjusting for patient characteristics. Higher-quality prescribing is found in facilities caring for a larger number of older veterans and facilities with formal geriatric education.

AB Objectives To determine the association between objectively measured sleep and subsequent placement in a nursing home or a personal care home. Design Prospective cohort. Setting Participants' homes and sites of the Study of Osteoporotic Fractures. Participants One thousand six hundred sixty-four community-dwelling women with a mean age of 83 +/- 4. Measurements At baseline, participants completed an average of 4 nights of wrist actigraphy; they provided data on place of residence at baseline and at follow-up, 5 years later. Results At baseline, participants had a mean total sleep time of 408 +/- 72 minutes, mean wake after sleep onset of 71 +/- 43 minutes, and mean sleep efficiency of 79 +/- 11%. At follow-up, 71 (4%) were residing in a nursing home, and 127 (8%) were in a personal care home. Women with the most wake after sleep onset (by quartile) had more than twice the odds as those with the least of placement in a nursing home (adjusted odds ratio (AOR) = 2.94, 95% confidence interval (CI) = 1.346.44) or a personal care home (AOR = 2.33, 95% CI = 1.264.30). Similarly, women with the lowest sleep efficiency had more than three times the odds as those with the highest of nursing home placement (AOR = 3.25, 95% CI = 1.35, 7.82) and more than twice the odds of placement in a personal care home (AOR = 2.38, 95% CI = 1.33, 4.24). There was no association between sleep duration and placement. Conclusion In very old community-dwelling women, greater wake after sleep onset and lower sleep efficiency are risk factors for placement in a nursing home or personal care home. Sleep duration alone does not appear to increase the risk of placement in these long-term care settings.

AB Objectives To determine the level of adherence to medications and characteristics of Part D beneficiaries associated with higher levels of antihypertensive medication adherence. Design Retrospective cohort study. Setting Medicare claims and Part D event files. Participants Medicare Part D enrollees with prevalent uncomplicated hypertension who filled at least one antihypertensive prescription in 2006 and two prescriptions in 2007. Measurements Medication adherence was defined as an average medication possession ratio of 80% or greater. Potential factors associated with adherence evaluated were age, sex, race or ethnicity, socioeconomic factors, comorbidity, medication use, copayments, being in the coverage gap, and number of unique prescribers. Results Overall adherence was 79.5% of 168,522 Medicare Part D enrollees with prevalent uncomplicated hypertension receiving antihypertensive medicines in 2007. In univariate analysis, adherence varied significantly according to most patient factors. In multivariable analysis, lower odds of adherence persisted for blacks (odds ratio (OR) = 0.53, 95% confidence interval (CI) = 0.510.55), Hispanics (OR = 0.58, 95% CI = 0.550.61), and other non-white races (OR = 0.80 95% CI = 0.750.85) than for whites. Greater comorbidity and concurrent medication use were also associated with poorer adherence. Adherence was significantly different across several geographic regions. Conclusion A number of associations were identified between patient factors and adherence to antihypertensive drugs, with significant differences in adherence according to ethnicity. Improving adherence could have significant public health implications and could improve outcomes specific to hypertension, as well as improving cost and healthcare utilization.

AB Cyclohexane 1,3-diones were identified as a class of molecules exhibiting a protective effect against mutant SOD1 induced toxicity in PC-12 cells, but an optimized analogue had little or no effect on life extension in the G93A SOD1 mouse model for amyotrophic lateral sclerosis (ALS). Additional testing showed that these compounds were inactive in neurons, and further analogue synthesis was carried out to identify compounds with neuronal activity. Starting from two racemic derivatives that were active in cortical neurons, two potent analogues (1b and 2b) were resolved, which were protective against mutant SOD1 induced toxicity in PC 12 cells. Both compounds were found to be active in cortical neurons and presented good ADME profiles in vitro. On the basis of these results, an ALS mouse trial with 1b was carried out, which showed slightly greater life extension than the FDA approved ALS drug riluzole, thereby validating cyclohexane 1,3-diones as a novel therapeutic class for the treatment of ALS.

AB Of 195 independent countries in the world, 83 have transplant programs. Some countries (areas) have emphasized living donation; others, decreased donation. As a consequence, rates of living donation vary widely between geographic areas and often between countries within the same geographic area. The major ethical issue in living donation is the risk to the donor. Internationally, numerous guidelines have been developed outlining acceptable donor evaluation and criteria for approval. An ongoing issue is that there remains considerable variation between countries (and programs within a country) in evaluation and in acceptance criteria. A major problem for most countries is the shortage of organs. As a consequence, illegal or quasi-legal unregulated markets have developed in some areas. These markets have not provided protection for either donor or recipient. The transplant community has taken a unified stand against these underground unregulated markets.

First published April 17, 2012; doi: 10.1152/ajpendo.00658.2011.-Insulin stimulates glycogen synthase (GS) through dephosphorylation of serine residues, and this effect is impaired in skeletal muscle from insulin-resistant [obese and type 2 diabetic (T2DM)] subjects. Exercise also increases GS activity, yet it is not known whether the ability of exercise to affect GS is impaired in insulin-resistant subjects. The objective of this study was to examine the effect of acute exercise on GS phosphorylation and enzyme kinetic properties in muscle from insulin-resistant individuals. Lean normal glucose-tolerant (NGT), obese NGT, and obese T2DM subjects performed 40 min of moderate-intensity cycle exercise (70% of Vo(2max)). GS kinetic properties and phosphorylation were measured in vastus lateralis muscle before exercise, immediately after exercise, and 3.5 h postexercise. In lean subjects, GS fractional activity increased twofold after 40 min of exercise, and it remained elevated after the 3.5-h rest period. Importantly, exercise also decreased GS K-m for UDP-glucose from approximate to 0.5 to approximate to 0.2 mM. In lean subjects, exercise caused significant dephosphorylation of GS by 50-70% (Ser(641), Ser(645), and Ser(645,649,653,657)), and phosphorylation of these sites remained decreased after 3.5 h; Ser(7) phosphorylation was not regulated by exercise. In obese NGT and T2DM subjects, exercise increased GS fractional activity, decreased K-m for UDP-glucose, and decreased GS phosphorylation as effectively as in lean NGT subjects. We conclude that the molecular regulatory process by which exercise promotes glycogen synthesis in muscle is preserved in insulin-resistant subjects.

First published May 4, 2012; doi: 10.1152/ajpheart.00241.2012.-Cardiac mammalian target of rapamycin (mTOR) is necessary and sufficient to prevent cardiac dysfunction in pathological hypertrophy. However, the role of cardiac mTOR in heart failure after ischemic injury remains undefined. To address this question, we used transgenic (Tg) mice with cardiac-specific overexpression of mTOR (mTOR-Tg mice) to study ischemia-reperfusion (I/R) injury in two animal models: 1) in vivo I/R injury with transient coronary artery ligation and 2) ex vivo I/R injury in Langendorff-perfused hearts with transient global ischemia. At 28 days after I/R, mortality was lower mTOR-Tg mice than littermate control mice [wild-type (WT) mice]. Echocardiography and MRI demonstrated that global cardiac function in mTOR-Tg mice was preserved, whereas WT mice exhibited significant cardiac dysfunction. Masson's trichrome staining showed that 28 days after I/R, the area of interstitial fibrosis was smaller in mTOR-Tg mice compared with WT mice, suggesting that adverse left ventricular remodeling is inhibited in mTOR-Tg mice. In the ex vivo I/R model, mTOR-Tg hearts demonstrated improved functional recovery compared with WT hearts. Perfusion with Evans blue after ex vivo I/R yielded less staining in mTOR-Tg hearts than WT hearts, indicating that mTOR overexpression inhibited necrosis during I/R injury. Expression of proinflammatory cytokines, including IL-6 and TNF-alpha, in mTOR-Tg hearts was lower than in WT hearts. Consistent with this, IL-6 in the effluent post-I/R injury was lower in mTOR-Tg hearts than in WT hearts. These findings suggest that cardiac mTOR overexpression in the heart is sufficient to provide substantial cardioprotection against I/R injury and suppress the inflammatory response.

First published April 18, 2012; doi:10.1152/ajprenal.00443.2011.-Increased albuminuria is a hallmark of early diabetic nephropathy, whereas the role of immunoglobulins (Igs), such as IgG (its 1-4 subtypes), IgA, and IgM, different in charge and size, has not been examined in early nephropathy in the past due to lack of a sensitive and reliable method. Our study group consisted of subjects with type 1 diabetes (T1D) and normoalbuminuria (n = 78), microalbuminuria (n = 78), and of 75 healthy subjects (HS). A Luminex-based immunoassay (1,000 time more sensitive than nephelometry-based method) was validated for the urine matrix and used for the measurements of IgG1-4, IgA, and IgM in our study groups. The Luminex-based assay detected Igs in 87% of HS subjects and in 100% of T1D subjects. Recovery of known amounts of Igs added to urine was 92-118%. In the normoalbuminuria group, urinary concentrations of albumin, IgG2, IgA, and IgM were significantly higher than in HS, whereas in the microalbuminuria, further elevation of IgG2, IgG4, and IgA was the most pronounced. In all three groups, fractional excretion of Igs was at least 100 times lower than that of albumin. Fractional excretion of IgG2 was the highest among all Igs. We validated a sensitive method for measuring Igs in urine using Luminex. We found that elevated concentrations of Igs, particularly in IgG2 and IgA, is present in subjects with T1D and no proteinuria. Elevation of those particular Ig subtypes suggests a contribution of novel mechanisms in early diabetic nephropathy, different from charge and size barrier impairment.

AB This phase III open-label trial investigated the efficacy of nilotinib in patients with advanced gastrointestinal stromal tumors following prior imatinib and sunitinib failure.
Patients were randomized 2 : 1 to nilotinib 400 mg b.i.d. or best supportive care (BSC; BSC without tyrosine kinase inhibitor, BSC + imatinib, or BSC + sunitinib). Primary efficacy end point was progression-free survival (PFS) based on blinded central radiology review (CRR). Patients progressing on BSC could cross over to nilotinib.
Two hundred and forty-eight patients enrolled. Median PFS was similar between arms (nilotinib 109 days, BSC 111 days; P = 0.56). Local investigator-based intent-to-treat (ITT) analysis showed a significantly longer median PFS with nilotinib (119 versus 70 days; P = 0.0007). A trend in longer median overall survival (OS) was noted with nilotinib (332 versus 280 days; P = 0.29). Post hoc subset analyses in patients with progression and only one prior regimen each of imatinib and sunitinib revealed a significant difference in median OS of > 4 months in favor of nilotinib (405 versus 280 days; P = 0.02). Nilotinib was well tolerated.
In the ITT analysis, no significant difference in PFS was observed between treatment arms based on CRR. In the post hoc subset analyses, nilotinib provided significantly longer median OS.

AB Hodgkin lymphoma (HL) survivors have an increased risk of secondary malignancies. We analyzed outcomes in patients with lung cancers following HL treatment.
Cases of thoracic malignancies were retrospectively identified from a multi-institutional database of 1976 patients treated for HL from 1969 to 2007. Data regarding risk factors, disease characteristics and outcomes were obtained from medical records.
Lung malignancies were identified in 55 patients a median of 19.5 years after initial HL therapy. Thirty-one patients (56%) had a > 10 pack-year history of tobacco use, 48 (87%) received thoracic irradiation and 26 (47%) received alkylating chemotherapy. Of the 42 patients with known stage at lung cancer diagnosis, 23 (55%) were stage IV and 5 (12%) were stage III. The method of lung cancer detection was known for 35 patients; of these, 12 (34%) were detected incidentally. Median survival time after diagnosis was 10 months for all 55 patients. Median survival time for patients with incidentally detected tumors has not been reached with a median follow-up of 39 months.
Lung malignancies diagnosed in patients successfully treated for HL generally have a dismal prognosis. However, a subset of patients diagnosed incidentally may have potentially curable disease.

A Randomized Trial
SO ANNALS OF SURGERY

DT Article
ID FINANCIAL INCENTIVES; CANCER; ADULTS
AB Objective: To assess the efficacy of a "spaced-education" game as a method of continuing medical education (CME) among physicians across the globe.
Background: The efficacy of educational games for the CME has yet to be established. We created a novel online educational game by incorporating game mechanics into "spaced education" (SE), an evidence-based method of online CME.
Methods: This 34-week randomized trial enrolled practicing urologists across the globe. The SE game consisted of 40 validated multiple-choice questions and explanations on urology clinical guidelines. Enrollees were randomized to 2 cohorts: cohort A physicians were sent 2 questions via an automated e-mail system every 2 days, and cohort B physicians were sent 4 questions every 4 days. Adaptive game mechanics re-sent the questions in 12 or 24 days if answered incorrectly and correctly, respectively. Questions expired if not answered on time (appointment dynamic). Physicians retired questions by answering each correctly twice-in-a-row (progression dynamic). Competition was fostered by posting relative performance among physicians. Main outcome measures were baseline scores (percentage of questions answered correctly upon initial presentation) and completion scores (percentage of questions retired).
Results: A total of 1470 physicians from 63 countries enrolled. Median baseline score was 48% (interquartile range [IQR] 17) and, in multivariate analyses, was found to vary significantly by region (Cohen d(max) = 0.31, P = 0.001) and age (d(max) = 0.41, P < 0.001). Median completion score was 98% (IQR 25) and varied significantly by age (d(max) = 0.21, P < 0.001) and American Board of Urology certification (d = 0.10, P = 0.033) but not by region (multivariate analyses). Question clustering reduced physicians' performance (d = 0.43, P < 0.001). Seventy-six percent of enrollees (1111/1470) requested to participate in future SE games.

AB Background: The effectiveness of photodynamic therapy (PDT) for cancer treatment correlates with apoptosis. We previously observed that the knockdown of ceramide synthase 6, an enzyme from the de novo sphingolipid biosynthesis pathway, is associated with marked reduction in C18-dihydroceramide and makes cells resistant to apoptosis post-PDT. Down-regulation of ceramide synthase 1 (CERS1) can also render cells resistant to anticancer drugs. Aim: To explore the impact of CERS1 knockdown on apoptosis and the sphingolipid profile, post-PDT, with the silicone phthalocyanine Pc 4, in a human head and neck squamous carcinoma cell line. Materials and Methods: Besides siRNA transfection and PDT treatment, the following methods were used: immunoblotting for protein expression, mass spectrometry for sphingolipid analysis, spectroflurometry and flow cytometry for apoptosis detection, and trypan blue assay for cell viability evaluation. Results: CERS1 knockdown led to inhibition of PDT-induced caspase 3-like (DEVDase) activation, of apoptosis and cell death. CERS1 knockdown was associated with global and selective decreases in ceramides and dihydroceramides, in particular C18-, C18:1- and C20-ceramide post-PDT. Conclusion: Our novel findings are consistent with the notion that CERS1 regulates apoptotic resistance to PDT, partly via C18- and C20-ceramide, and that CERS1 is a molecular target for controlling resistance to PDT.

TI Plasma Amyloid-beta as a Predictor of Dementia and Cognitive Decline A
Systematic Review and Meta-analysis

DT Review
ID ALZHEIMERS-DISEASE; A-BETA; FOLLOW-UP; RISK; METAANALYSIS; ASSOCIATION;
HOMOCYSTEINE; IMPAIRMENT; CONVERSION; A-BETA-42
AB Background: Preclinical prediction of Alzheimer disease (AD) is important and critical to effective intervention. Plasma levels of amyloid-beta (A beta) peptides have been a principal focus of the growing literature on blood-based biomarkers, but studies to date have varied in design, assay methods, and sample size, making it difficult to readily interpret the overall data.
Objective: To conduct a systematic review and meta-analysis of relevant prospective studies to determine whether plasma amyloid-beta levels may predict development of dementia, AD, and cognitive decline.
Design: We searched prospective studies published between 1995 and 2011 indexed in the MEDLINE, EMBASE, and PsycINFO databases. Selected studies included those measuring at least 1 relevant plasma amyloid-beta species (A beta(40), A beta(42), or A beta(42): A beta(40) ratio) and reporting an effect estimate for dementia, AD, or cognitive change.
Main Outcome Measures: Using a standardized extraction form, appropriate study parameters on subject information, exposure, and outcomewere extracted. Random effects models were used to generate summary risk ratios and 95% confidence intervals comparing the bottom vs top quantiles for each plasma measure.
Results: Thirteen studies with a total of 10 303 subjects met inclusion criteria for meta-analysis. Lower A beta(42): A beta(40) ratios were significantly associated with development of AD (summary risk ratio, 1.60; 95% CI, 1.04-2.46; P=.03) and dementia (risk ratio, 1.67; 95% CI, 1.02-2.75; P=.04). Significant heterogeneity was found for both summary estimates, which could not be explained by participants' age, sex distribution, the study's follow-up time, or year of publication. Plasma levels of A beta(40) and A beta(42) alone were not significantly associated with either outcome.
Conclusions: Overall, the literature indicates that plasma A beta(42): A beta(40) ratios predict development of AD and dementia. However, significant heterogeneity in the meta-analysis underlines the need for substantial further investigation of plasma amyloid-beta levels as a preclinical biomarker.

AB Background: Aberrant accumulation of transition metals in the brain may have an early and important role in the pathogenesis of several neurodegenerative disorders, including Huntington disease (HD).
Objective: To comprehensively evaluate and validate the distribution of metal deposition in the brain using advanced magnetic resonance imaging methods from the premanifest through symptomatic stages of HD.
Design: Observational study.
Setting: University imaging center.
Participants: Twenty-eight HD expanded gene carriers, 34 patients with symptomatic HD, and 56 age-and sex-matched healthy control subjects were included in the study.
Interventions: Participants underwent magnetic resonance imaging for the quantification of the phase evolution of susceptibility-weighted images.
Main Outcome Measures: To verify the identity of the metals responsible for the changes in the phase evolution of the susceptibility signal in the brain and to assess correlations with systemic levels. Inductively coupled plasma mass spectrometry was used to measure transition metal concentrations in postmortem brains.
Results: In the basal ganglia, progressive increases in the phase evolution were found in HD, beginning in premanifest individuals who were far from expected onset and increasing with proximity to expected onset and thereafter. Increases in the cerebral cortex were regionally selective and present only in symptomatic HD. Increases were verified by excessive deposition of brain iron, but a complex alteration in other transition metals was found.
Conclusion: An important and early role of altered metal homeostasis is suggested in the pathogenesis of HD.

AB A consensus conference was held in order to provide guidelines for the use of adjuvant therapy in patients with Stage I carcinoma of the breast, using traditional information, such as tumor size, microscopic character, Nottingham index, patient age and co-morbidities, but also incorporating steroid hormone and Her-2-neu data as well as other immunohistochemical markers. The role of the genetic analysis of breast cancer and proprietary gene prognostic signatures was discussed, along with the molecular profiling of breast cancers into several groups that may predict prognosis. These molecular data are not currently sufficiently mature to make them part of decision making algorithms of recommendations for the treatment of individual patients.

AB Cancer survivors are often highly motivated to seek information about food choices, physical activity, and dietary supplements to improve their treatment outcomes, quality of life, and overall survival. To address these concerns, the American Cancer Society (ACS) convened a group of experts in nutrition, physical activity, and cancer survivorship to evaluate the scientific evidence and best clinical practices related to optimal nutrition and physical activity after the diagnosis of cancer. This report summarizes their findings and is intended to present health care providers with the best possible information with which to help cancer survivors and their families make informed choices related to nutrition and physical activity. The report discusses nutrition and physical activity guidelines during the continuum of cancer care, briefly highlighting important issues during cancer treatment and for patients with advanced cancer, but focusing largely on the needs of the population of individuals who are disease free or who have stable disease following their recovery from treatment. It also discusses select nutrition and physical activity issues such as body weight, food choices, food safety, and dietary supplements; issues related to selected cancer sites; and common questions about diet, physical activity, and cancer survivorship.

AB Background: Advantages offered by canine population substructure, combined with clinical presentations similar to human disorders, makes the dog an attractive system for studies of cancer genetics. Cancers that have been difficult to study in human families or populations are of particular interest. Histiocytic sarcoma is a rare and poorly understood neoplasm in humans that occurs in 15% to 25% of Bernese Mountain Dogs (BMD).
Methods: Genomic DNA was collected from affected and unaffected BMD in North America and Europe. Both independent and combined genome-wide association studies (GWAS) were used to identify cancer-associated loci. Fine mapping and sequencing narrowed the primary locus to a single gene region.
Results: Both populations shared the same primary locus, which features a single haplotype spanning MTAP and part of CDKN2A and is present in 96% of affected BMD. The haplotype is within the region homologous to human chromosome 9p21, which has been implicated in several types of cancer.
Conclusions: We present the first GWAS for histiocytic sarcoma in any species. The data identify an associated haplotype in the highly cited tumor suppressor locus near CDKN2A. These data show the power of studying distinctive malignancies in highly predisposed dog breeds.
Impact: Here, we establish a naturally occurring model of cancer susceptibility due to CDKN2 dysregulation, thus providing insight about this cancer-associated, complex, and poorly understood genomic region. Cancer Epidemiol Biomarkers Prey; 21(7); 1019-27. (C)2012 AACR.

AB Background: To compare the skin and breast/cervical cancer prevention /screening practices of adult siblings of childhood cancer survivors with controls and to identify modifying factors for these practices.
Methods: Cross-sectional, self-report data from 2,588 adult siblings of 5+ year survivors of childhood cancer were analyzed to assess cancer prevention/screening practices. Two age, sex, and race/ethnicity-matched samples (N = 5,915 and N = 37,789) of the Behavioral Risk Factor Surveillance System participants served as the comparison populations. Sociodemographic and cancer-related data were explored as modifying factors for sibling cancer prevention/screening practices through multivariable logistic regression.
Results: Compared with controls, siblings were more likely to practice skin cancer prevention behaviors: use of protective clothing [OR, 2.85; 95% confidence interval (CI), 2.39-3.39], use of shade (OR, 2.11; 95% CI, 1.88-2.36), use of sunscreen (OR, 1.27; 95% CI, 1.14-1.40), and wearing a hat (OR, 1.77; 95% CI, 1.58-1.98). No differences were noted for breast/cervical cancer screening including mammography and Pap testing. Having less than a high school education and lack of health insurance were associated with diminished cancer prevention/screening behaviors. Survivor diagnosis, treatment intensity, adverse health, chronic health conditions, and second cancers were not associated with sibling cancer prevention /screening behaviors.
Conclusions: Siblings of cancer survivors report greater skin cancer prevention practices when compared with controls; however, no differences were noted for breast/cervical cancer screening practices. Access to care and lack of education may be associated with decreased cancer prevention /screening behaviors. Interventions are needed to address these barriers.
Impact: Research should be directed at understanding the impact of the cancer experience on sibling health behaviors. Cancer Epidemiol Bioinarkers Prev; 21(7); 1078-88. (C)2012 AACR.

AB Background: Delirium evaluation in patients in the ICU requires the use of an arousal/sedation assessment tool prior to assessing consciousness. The Richmond Agitation-Sedation Scale (BASS) and the Riker Sedation-Agitation Scale (SAS) are well-validated arousal/sedation tools. We sought to assess the concordance of BASS and SAS assessments in determining eligibility of patients in the ICU for delirium screening using the confusion assessment method for the ICU (CAM-ICU).
Methods: We performed a prospective cohort study in the adult medical, surgical, and progressive (step-down) ICUs of a tertiary care, university-affiliated, urban hospital in Indianapolis, Indiana. The cohort included 975 admissions to the ICU between January and October 2009.
Results: The outcome measures of interest were the correlation and agreement between RASS and SAS measurements. In 2,469 RASS and SAS paired screens, the rank correlation using the Spearman correlation coefficient was 0.91, and the agreement between the two screening tools for assessing CAM-ICU eligibility as estimated by the K coefficient was 0.93. Analysis showed that 70.1% of screens were eligible for CAM-ICU assessment using BASS (7.1% sedated [BASS -3 to -1]; 62.6% calm [0]; and 0.4% restless, agitated [+1 to +3]), compared with 72.1% using SAS (5% sedated [SAS 3]; 66.5% calm [4]; and 0.6% anxious, agitated [5, 6]). In the mechanically ventilated subgroup, RASS identified 19.1% CAM-ICU eligible patients compared with 24.6% by SAS. The correlation coefficient in this subgroup was 0.70 and the agreement was 0.81.
Conclusion: Both SAS and BASS led to similar rates of delirium assessment using the CAM-ICU. CHEST 2012; 142(1):48-54

PREFERENCES; CLINICIAN; PROGNOSIS; INSIGHTS; BARRIERS; DEATH
AB Background: Despite strong preferences for discussions about end-of-life care, patients with COPD do not often have these discussions with their providers. Our objective was to determine whether patients who reported having end-of-life discussions also reported higher perceived markers of quality of care and health status.
Methods: A cross-sectional study of data collected at baseline for a trial to improve the occurrence and quality of end-of-life communication in patients with COPD was conducted. The primary exposure was self-reported acknowledgment of having discussions about end-of-life planning with their physicians. The primary outcome measures were patient-reported quality of care and satisfaction with care, which were dichotomized as best imaginable quality of care vs other ratings of quality and highest satisfaction vs other ratings of satisfaction. We adjusted for confounding factors, including patient and provider characteristics, using logistic regression clustered by provider.
Results: Three hundred seventy-six patients were enrolled, of whom 55 (14.6%) reported having end-of-life discussions. Individuals who reported having end-of-life discussions with their physicians were significantly more likely to rate their quality of care as the best imaginable (OR, 2.07; 95% CI, 1.05-4.09) and to be very satisfied with their medical care (OR, 1.98; 95% CI, 1.10-3.55). Discussions were more likely to have occurred among patients with worse health status as measured by St. George Respiratory Questionnaire total and impact scores.
Conclusions: Patients who reported having end-of-life care discussions with their physicians had higher perceived quality of care and satisfaction with their physicians. Discussing end-of-life care with patients who have COPD may improve their perceived overall quality of and satisfaction with care. CHEST 2012; 142(1):128-133

AB Obstructive sleep apnea (OSA) is a condition of repetitive upper airway collapse, which occurs during sleep. Recent literature has emphasized the role of OSA in contributing to glucose intolerance, dyslipidemia, and hypertension. OSA is associated with the development of cardiovascular disease, although definitive data are sparse with regard to the prevention of cardiovascular disease and CPAP therapy. CPAP provides effective treatment for OSA, but patient adherence remains challenging. Aside from daytime symptom improvement, it is difficult to monitor the adequacy of treatment response. Thus, the search for a biomarker becomes critical. The discovery of an ideal biomarker for OSA has the potential to provide information related to diagnosis, severity, prognosis, and response to treatment. In addition, because large-scale randomized controlled trials are both ethically and logistically challenging in assessing hard cardiovascular outcomes, certain biomarkers may be reasonable surrogate outcome measures. This article reviews the literature related to potential biomarkers of OSA with the recognition that an ideal biomarker does not exist at this time. CHEST 2012; 142(1):239-245

AB BACKGROUND: Low-level mutations in clinical tumor samples often reside below mutation detection limits, thus leading to false negatives that may impact clinical diagnosis and patient management. COLD-PCR (co-amplification at lower denaturation temperature PCR) is a technology that magnifies unknown mutations during PCR, thus enabling downstream mutation detection. However, a practical difficulty in applying COLD-PCR has been the requirement for strict control of the denaturation temperature for a given sequence, to within +/- 0.3 degrees C. This requirement precludes simultaneous mutation enrichment in sequences of substantially different melting temperature (T-m) and limits the technique to a single sequence at a time. We present a temperature-tolerant (TT) approach (TT-COLD-PCR) that reduces this obstacle.
METHODS: We describe thermocycling programs featuring a gradual increase of the denaturation temperature during COLD-PCR. This approach enabled enrichment of mutations when the cycling achieves the appropriate critical denaturation temperature of each DNA amplicon that is being amplified. Validation was provided for KRAS (v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog) and TP53 (tumor protein p53) exons 6-9 by use of dilutions of mutated DNA, clinical cancer samples, and plasma-circulating DNA.
RESULTS: A single thermocycling program with a denaturation-temperature window of 2.5-3.0 degrees C enriches mutations in all DNA amplicons simultaneously, despite their different T(m)s. Mutation enrichments of 6-9-fold were obtained with TT-full-COLD-PCR. Higher mutation enrichments were obtained for the other 2 forms of COLD-PCR, fast-COLD-PCR, and ice-COLD-PCR.
CONCLUSIONS: Low-level mutations in diverse amplicons with different Tins can be mutation enriched via TT-COLD-PCR provided that their T(m)s fall within the denaturation-temperature window applied during amplification. This approach enables simultaneous enrichment of mutations in several amplicons and increases significantly the versatility of COLD-PCR. (c) 2012 American Association for Clinical Chemistry

AB Background and objectives Kidney Disease Improving Global Outcomes guidelines recommend against bone mineral density (BMD) screening in CKD patients with mineral bone disease, due to a lack of association of BMD with fractures in cross-sectional studies in CKD. We assessed whether BMD is associated with fractures in participants with and without CKD in the Health, Aging, and Body Composition study, a prospective study of well functioning older individuals.
Design, setting, participants, & measurements Hip BMD was measured by dual-energy x-ray absorptiometry. Osteoporosis was defined as a femoral neck BMD (FNBMD) T score below -2.5 and CKD as an estimated GFR <60 ml/min per 1.73 m(2). The association of BMD with incident nonspine, fragility fractures to study year 11 was analyzed using Cox proportional hazards analyses, adjusting for age, race, sex, body mass index, hyperparathyroidism, low vitamin D level, and CKD. Interaction terms were used to assess whether the association of BMD with fracture differed in those with and without CKD.
Results There were 384 incident fractures in 2754 individuals (mean age 73.6 years). Lower FNBMD was associated with greater fracture, regardless of CKD status. After adjustment, the hazard ratios (95% confidence intervals) were 2.74 (1.99, 3.77) and 2.15 (1.80, 2.57) per lower SD FNBMD for those with and without CKD, respectively (interaction P=0.68), and 2.10 (1.23, 3.59) and 1.63 (1.18, 2.23) among those with osteoporosis in patients with and without CKD, respectively (interaction P=0.75).
Conclusions BMD provides information on risk for fracture in older individuals with or without moderate CKD. Clin J Am Soc Nephrol 7: 1130-1136, 2012. doi: 10.2215/CJN.12871211

AB Objectives:
To compare adherence to second-generation tyrosine kinase inhibitors (TKIs) dasatinib and nilotinib in patients with imatinib resistant or intolerant chronic myeloid leukemia (CML) receiving second-line therapies.
Methods:
Two U. S. administrative claims databases were reviewed (January 1997 to March 2011) for CML patients previously treated with imatinib, who received >= 1 prescription of dasatinib or nilotinib and had continuous enrollment >= 1 month before and after the index date (first dasatinib or nilotinib prescription date). Medication possession ratios (MPRs) and proportion of days covered (PDCs) were evaluated between the treatment initiation date until the end of continuous eligibility, for a maximum of 12 months. Sensitivity analyses were conducted to compare patients initiated on nilotinib to patients who initiated dasatinib 100 mg/day and 140 mg/day separately. This study provides updated results of a previously published study.
Results:
In total, 878 CML patients who received second-line treatment with either dasatinib (n = 550) or nilotinib (n = 328) were studied. Dasatinib users were less adherent compared to nilotinib users; mean MPR was 0.739 (standard deviation [SD] 0.246) for dasatinib and 0.800 (SD 0.246) for nilotinib (adjusted difference 0.061; P = 0.002). Subgroup analyses of patients who initiated dasatinib 100 mg/day and 140 mg/day separately presented similar trends; after multivariate adjustment, adherence was 0.039 points lower in the 100 mg/day group (P = 0.034) and 0.120 points lower in the 140 mg/day group (P<0.001).
Conclusions:
Among patients treated in the second-line CML setting, those treated with nilotinib had significantly higher adherence compared to patients treated with dasatinib, regardless of dasatinib dose (100 mg/day and 140 mg/day).
Limitations:
The study was subject to common limitations of claims data, which lack clinical information, may contain inaccuracies in diagnosis and procedure coding, and may not truly reflect actual drug consumption. Moreover, daily doses calculated based on refill records may not reflect accurate dosing regimens.

ID EDUCATION-PROGRAM; MANAGEMENT; KNOWLEDGE; SCALE
AB Background: Evidence suggests that empowerment is an important factor to address everyday aspects of dealing with a chronic disease. This study evaluated the effect of diabetes empowerment on medication adherence and self-care behaviors in adults with type 2 diabetes.
Subjects and Methods: Data on 378 subjects with type 2 diabetes recruited from two primary care clinics in the southeastern United States were examined. Previously validated scales were used to measure diabetes empowerment, medication adherence, diabetes knowledge, and diabetes self-care behaviors (including diet, physical activity, blood sugar testing, and foot care). Multiple linear regression was used to assess the independent effect of diabetes empowerment on medication adherence and self-care behaviors controlling for relevant covariates.
Results: Eighty-three percent were non-Hispanic blacks, 69% were women, 22% were 65 years or older, 68% were not married, 26% had less than high school education, 60% were unemployed, 39% were uninsured, and 47% had a yearly income <$10,000. Empowerment had significant correlations with medication adherence (r = 0.17, P < 0.003), diabetes knowledge (r = 0.16, P = 0.007), diet (r = 0.24, P < 0.001), exercise (r = 0.25, P < 0.001), blood sugar testing (r = 0.12, P = 0.043), and foot care (r = 0.18, P = 0.002). In the regression model, diabetes empowerment was significantly associated with medication adherence (beta = -0.04, P = 0.001), diabetes knowledge (beta = 0.09, P = 0.012), diet (beta = 0.09, P < 0.001), exercise (beta = 0.10, P < 0.001), blood sugar testing (beta = 0.07, P = 0.016), and foot care (beta = 0.08, P = 0.001).
Conclusions: In this sample, diabetes empowerment was related to better diabetes knowledge, medication adherence and improved self-care behaviors. Emphasis on empowerment and self-efficacy is relevant to improve outcomes in the management of diabetes.

AB Atrioventricular valve development commences with an EMT event whereby endocardial cells transform into mesenchyme. The molecular events that induce this phenotypic change are well understood and include many growth factors, signaling components, and transcription factors. Besides their clear importance in valve development, the role of these transformed mesenchyme and the function they serve in the developing prevalve leaflets is less understood. Indeed, we know that these cells migrate, but how and why do they migrate? We also know that they undergo a transition to a mature, committed cell, largely defined as an interstitial fibroblast due to their ability to secrete various matrix components including collagen type I. However, we have yet to uncover mechanisms by which the matrix is synthesized, how it is secreted, and how it is organized. As valve disease is largely characterized by altered cell number, cell activation, and matrix disorganization, answering questions of how the valves are built will likely provide us with information of real clinical relevance. Although expression profiling and descriptive or correlative analyses are insightful, to advance the field, we must now move past the simplicity of these assays and ask fundamental, mechanistic based questions aimed at understanding how valves are "built". Herein we review current understandings of atrioventricular valve development and present what is known and what isn't known. In most cases, basic, biological questions and hypotheses that were presented decades ago on valve development still are yet to be answered but likely hold keys to uncovering new discoveries with relevance to both embryonic development and the developmental basis of adult heart valve diseases. Thus, the goal of this review is to remind us of these questions and provide new perspectives on an old theme of valve development.

AB Background: Although the Veterans Affairs and Department of Defense (VA/DoD) clinical guidelines for management of posttraumatic stress disorder (PTSD) recommend against routine benzodiazepine use, little is known about the trends and clinical and prescription profiles of benzodiazepine use since these guidelines were released in 2004.
Methods: This retrospective study included 64,872 patients with a PTSD diagnosis received from care at facilities in VA Northwest Veterans Integrated Service Network (VISN 20) during 2003-2010. Annual prevalence of any use was defined as any prescription for benzodiazepines, and long-term use was defined as >90 days' supply, in a year. Gender-specific logistic regressions were fit to estimate any and long-term benzodiazepine use, test for linear trends over 8-years and explore factors associated with trends.
Results: The trend of age-adjusted benzodiazepine use over 8-years rose significantly from 25.0 to 26.8% among men and 31.2 to 38.8% among women. Long-term use in men and women increased from 15.4 to 16.4% and 18.0 to 22.7%, respectively. Comorbid psychiatric and alcohol use disorders (AUD) were associated with a greater increase in long-term use of benzodiazepines. In 2010, 61% of benzodiazepine users received >90 days' supply. Among those prescribed benzodiazepines long-term, 11% had AUD and 47% were also prescribed opioids long-term.
Conclusion: Despite VA/DoD clinical guidelines recommending against routine use of benzodiazepines for PTSD, the adjusted prevalence of long-term use increased among men and women with PTSD in VISN 20. Widespread concomitant use of benzodiazepines and opioids suggests risk management systems and research on the efficacy and safety of these medications are needed. Published by Elsevier Ireland Ltd.

AB How can pain complaints be elicited and analyzed so as to increase the empathic bond between patient and clinician? I will argue that though Wierzbicka's approach to this question is useful-an exploration of certain abstract dimensions of pain's meaning-it fails to examine key aspects that are the most useful and crucial for cultural analysis and for building empathic bonds between the clinician and patient. Not just a grammar of pain is needed; rather a biological philology of pain.

AB Purpose: Disrupted sleep patterns in children with epilepsy and their parents are commonly described clinically. A number of studies have shown increased frequency of sleep disorders among pediatric epilepsy patients; however, few have characterized the association between epilepsy and parental sleep quality and household sleeping arrangements. The purpose of this study was to explore the effect of pediatric epilepsy on child sleep, parental sleep and fatigue, and parent-child sleeping arrangements, including room sharing and cosleeping. Methods: Parents of children 2 to 10 years of age with and without epilepsy completed written questionnaires assessing seizure history, child and parent sleep, and household sleeping arrangements. Childrens Sleep Habits Questionnaire (CSHQ) scores were used to evaluate sleep disturbances for the child. The Pittsburgh Sleep Quality Index (PSQI) and the Iowa Fatigue Scale (IFS) were used to evaluate parental sleep and fatigue, respectively. The Early Childhood Epilepsy Severity Scale (E-Chess) was used to assess epilepsy severity. Key Findings: One hundred five households with a child with epilepsy and 79 controls participated in this study. Households with a child with epilepsy reported increased rates of both parentchild room sharing (p < 0.001) and cosleeping (p = 0.005) compared to controls. Children with epilepsy were found to have greater sleep disturbance by total CSHQ score (p < 0.001) and the following subscores: parasomnias (p < 0.001), night wakings (p < 0.001), sleep duration (p < 0.001), daytime sleepiness (<0.001), sleep onset delay (p = 0.009), and bedtime resistance (p = 0.023). Parents of children with epilepsy had increased sleep dysfunction (p = 0.005) and were more fatigued (p < 0.001). Severity of epilepsy correlated positively with degree of child sleep dysfunction (0.192, p = 0.049), parental sleep dysfunction (0.273, p = 0.005), and parental fatigue (0.324, p = 0.001). Antiepileptic drug polytherapy was predictive of greater childhood sleep disturbances. Nocturnal seizures were associated with parental sleep problems, whereas room sharing and cosleeping behavior were associated with child sleep problems. Within the epilepsy cohort, 69% of parents felt concerned about night seizures and 44% reported feeling rested rarely or never. Finally, 62% of parents described decreased sleep quality and/or quantity with cosleeping. Significance: Pediatric epilepsy can significantly affect sleep patterns for both the affected child and his or her parents. Parents frequently room share or cosleep with their child, adaptations which may have detrimental effects for many households. Clinicians must not only be attentive to the sleep issues occurring in pediatric patients with epilepsy, but also for the household as a whole. These data provide evidence of a profound clinical need for improved epilepsy therapeutics and the development of nocturnal seizure monitoring technologies.

ID EMOTIONAL APPROACH; MANAGEMENT; SCALE
AB Background: Few studies have examined the emotional approach to coping on diabetes outcomes. This study examined the relationship between emotional coping and diabetes knowledge, medication adherence and self-care behaviors in adults with type 2 diabetes.
Methods: Data on 378 subjects with type 2 diabetes recruited from two primary care clinics in the southeastern United States were examined. Previously validated scales were used to measure coping, medication adherence, diabetes knowledge and diabetes self-care behaviors (including diet, physical activity, blood sugar testing and foot care). Multiple linear regression was used to assess the independent effect of coping through emotional approach on medication adherence and self-care behaviors while controlling for relevant covariates.
Results: Significant correlations were observed between emotional coping [as measured by emotional expression (EE) and emotional processing (EP)] and self-care behaviors. In the linear regression model, EP was significantly associated with medication adherence [beta -0.17, 95% confidence interval (CI) -0.32 to -0.015], diabetes knowledge (beta 0.76, 95% CI 0.29 to 1.24), diet (beta 0.52, 95% CI 0.24 to 0.81), exercise (beta 0.51, 95% CI 0.19 to 0.82), blood sugar testing (beta 0.54, 95% CI 0.16 to 0.91) and foot care (beta 0.32, 95% CI -0.02 to 0.67). On the other hand, EE was associated with diet (beta 0.38, 95% CI 0.13 to 0.64), exercise (beta 0.54, 95% CI 0.27 to 0.82), blood sugar testing (beta 0.42, 95% CI 0.09 to 0.76) and foot care (beta 0.36, 95% CI 0.06 to 0.66), but it was not associated with diabetes knowledge.
Conclusion: These findings indicate that coping through an emotional approach is significantly associated with behaviors that lead to positive diabetes outcomes. (C) 2012 Elsevier Inc. All rights reserved.

TI Bottlenecks in the Emergency Department: the psychiatric clinicians'

SO GENERAL HOSPITAL PSYCHIATRY

ID LENGTH-OF-STAY; PERCEPTIONS; VISITS; ROOM
AB Objective: To ask psychiatric clinicians for their perspectives on the rate-limiting steps (RLS) in patient care in the Emergency Department (ED) and to compare them to the patient's actual length of stay.
Method: Prospective cohort study of clinicians' perspectives on the RLS among 1092 adult ED patients. Medical records were abstracted for ED time and other data.
Results: Clinicians identified five RLS: limited availability of staff, limited availability of beds after discharge, need for clinical stability, need for additional history and patient's financial issues. The last RLS was the only one not associated with increased wait times in the ED. There were significant differences in the patterns of RLS by trainee status and hospital. For example, significantly higher proportions of trainees reported that RLS in patient care were due to the need for clinical stability and additional history and lack of bed availability. In contrast, non-trainee clinicians were more likely to cite problems with the availability of ED staff as an RLS.
Conclusions: Most of the RLS in patient care identified by clinicians were associated with actual increases in ED wait time for their patients. Next steps include asking clinicians for possible solutions to the delays their patients experience. Published by Elsevier Inc.

AB The maintenance of genome stability is critical for survival, and its failure is often associated with tumorigenesis. The Fanconi anemia (FA) pathway is essential for the repair of DNA interstrand cross-links (ICLs), and a germline defect in the pathway results in FA, a cancer predisposition syndrome driven by genome instability. Central to this pathway is the monoubiquitination of FANCD2, which coordinates multiple DNA repair activities required for the resolution of ICLs. Recent studies have demonstrated how the FA pathway coordinates three critical DNA repair processes, including nucleolytic incision, translesion DNA synthesis (TLS), and homologous recombination (HR). Here, we review recent advances in our understanding of the downstream ICL repair steps initiated by ubiquitin-mediated FA pathway activation.

BIOGENESIS
AB RNA silencing can be initiated by endogenous or exogenously delivered siRNAs. In Caenorhabditis elegans, RNA silencing guided by primary siRNAs is inefficient and therefore requires an siRNA amplification step involving RNA-dependent RNA polymerases (RdRPs). Many factors involved in RNA silencing localize to protein- and RNA-rich nuclear pore-associated P granules in the germline, where they are thought to surveil mRNAs as they exit the nucleus. Mutator class genes are required for siRNA-mediated RNA silencing in both germline and somatic cells, but their specific roles and relationship to other siRNA factors are unclear. Here we show that each of the six mutator proteins localizes to punctate foci at the periphery of germline nuclei. The Mutator foci are adjacent to P granules but are not dependent on core P-granule components or other RNAi pathway factors for their formation or stability. The glutamine/asparagine (Q/N)-rich protein MUT-16 is specifically required for the formation of a protein complex containing the mutator proteins, and in its absence, Mutator foci fail to form at the nuclear periphery. The RdRP RRF-1 colocalizes with MUT-16 at Mutator foci, suggesting a role for Mutator foci in siRNA amplification. Furthermore, we demonstrate that genes that yield high levels of siRNAs, indicative of multiple rounds of siRNA amplification, are disproportionally affected in mut-16 mutants compared with genes that yield low levels of siRNAs. We propose that the mutator proteins and RRF-1 constitute an RNA processing compartment required for siRNA amplification and RNA silencing.

AB Multidimensional cancer genome analysis and validation has defined Quaking (QKI), a member of the signal transduction and activation of RNA (STAR) family of RNA-binding proteins, as a novel glioblastoma multiforme (GBM) tumor suppressor. Here, we establish that p53 directly regulates QKI gene expression, and QKI protein associates with and leads to the stabilization of miR-20a; miR-20a, in turn, regulates TGF beta R2 and the TGF beta signaling network. This pathway circuitry is substantiated by in silico epistasis analysis of its components in the human GBM TCGA (The Cancer Genome Atlas Project) collection and by their gain- and loss-of-function interactions in in vitro and in vivo complementation studies. This p53-QKI-miR-20a-TGF beta pathway expands our understanding of the p53 tumor suppression network in cancer and reveals a novel tumor suppression mechanism involving regulation of specific cancer-relevant microRNAs.

AB Purpose: Lynch syndrome accounts for 2-5% of endometrial cancer cases. Lynch syndrome prediction models have not been evaluated among endometrial cancer cases.
Methods: Area under the receiver operating curve (AUC), sensitivity and specificity of PREMM1,2,6, MMRpredict, and MMRpro scores were assessed among 563 population-based and 129 clinic-based endometrial cancer cases.
Results: A total of 14 (3%) population-based and 80 (62%) clinic-based subjects had pathogenic mutations. PREMM1,2,6, MMRpredict, and MMRpro were able to distinguish mutation carriers from -noncarriers (AUC of 0.77, 0.76, and 0.77, respectively), among -population-based cases. All three models had lower discrimination for the clinic-based cohort, with AUCs of 0.67, 0.64, and 0.54, respectively. Using a 5% cutoff, sensitivity and specificity were as follows: PREMM1,2,6, 93% and 5% among population-based cases and 99% and 2% among clinic-based cases; MMRpredict, 71% and 64% for the population-based cohort and 91% and 0% for the clinic-based cohort; and MMRpro, 57% and 85% among population-based cases and 95% and 10% among clinic-based cases.
Conclusion: Currently available prediction models have limited clinical utility in determining which patients with endometrial cancer should undergo genetic testing for Lynch syndrome. Immunohistochemical analysis and microsatellite instability testing may be the best currently available tools to screen for Lynch syndrome in endometrial cancer patients.

AB PURPOSE: The purpose of this study was to compare the effects of a 24-week walking with poles rehabilitation program with a traditional 24-week walking program on physical function in patients with peripheral arterial disease (PAD).
METHODS: Patients with PAD (n = 103, age = 69.7 +/- 8.9 years, ankle-brachial index < 0.90 or evidence of calcified vessels) were randomized into a rehabilitation program of traditional walking (n = 52) or walking with poles (n = 51). Patients exercised 3 times per week for 24 weeks. Exercise endurance was measured by time walked on a constant work rate treadmill test at 6, 12, and 24 weeks. Perceived physical function was measured by the Medical Outcomes Study Short Form-36 and Walking Impairment Questionnaire. Tissue oxygenation was measured using near-infrared spectroscopy.
RESULTS: Patients assigned to the traditional walking group walked longer at 24 weeks than those assigned to the pole walking group (21.10 +/- 17.07 minutes and 15.02 +/- 12.32 minutes, respectively, P = .037). There were no differences between the groups in tissue oxygenation. However, there was a significant lengthening of time for which it took to reach minimum tissue oxygenation values (P < .001) within the groups on the constant work rate test. There were no differences between the groups in perceived physical function as measured by the Physical Function subscale on the Medical Outcomes Study Short Form-36 or perceived walking distance as measured by the Walking Distance subscale on the Walking Impairment Scale.
CONCLUSIONS: Traditional walking was superior to walking with poles in increasing walking endurance on a constant work rate treadmill test for patients with PAD.

TI Phase I Pharmacologic and Pharmacodynamic Study of the Gamma Secretase
(Notch) Inhibitor MK-0752 in Adult Patients With Advanced Solid Tumors

LA English
DT Article
ID ACUTE LYMPHOBLASTIC LEUKEMIA/LYMPHOMA; STEM-CELLS; PATHWAY;

AB Purpose
Aberrant Notch signaling has been implicated in the pathogenesis of many human cancers. MK-0752 is a potent, oral inhibitor of gamma-secretase, an enzyme required for Notch pathway activation. Safety, maximum-tolerated dose, pharmacokinetics (PKs), pharmacodynamics, and preliminary antitumor efficacy were assessed in a phase I study of MK-0752.
Patients and Methods
MK-0752 was administered in three different schedules to patients with advanced solid tumors. Hair follicles were collected at higher dose levels to assess a gene signature of Notch inhibition.
Results
Of 103 patients who received MK-0752, 21 patients received a continuous once-daily dosing at 450 and 600 mg; 17 were dosed on an intermittent schedule of 3 of 7 days at 450 and 600 mg; and 65 were dosed once per week at 600, 900, 1,200, 1,500, 1,800, 2,400, 3,200, and 4,200 mg. The most common drug-related toxicities were diarrhea, nausea, vomiting, and fatigue. PKs (area under the concentration-time curve and maximum measured plasma concentration) increased in a less than dose proportional manner, with a half-life of approximately 15 hours. Significant inhibition of Notch signaling was observed with the 1,800- to 4,200-mg weekly dose levels, confirming target engagement at those doses. One objective complete response and an additional 10 patients with stable disease longer than 4 months were observed among patients with high-grade gliomas.
Conclusion
MK-0752 toxicity was schedule dependent. Weekly dosing was generally well tolerated and resulted in strong modulation of a Notch gene signature. Clinical benefit was observed, and rational combination trials are currently ongoing to maximize clinical benefit with this novel agent.

TI Acute Myeloid Leukemia and Myelodysplastic Syndromes After Radiation
Therapy Are Similar to De Novo Disease and Differ From Other

ID DOUBLE-STRAND BREAKS; ALLOGENEIC TRANSPLANTATION; SECONDARY LEUKEMIAS;
CYTOSTATIC AGENTS; HODGKINS-LYMPHOMA; RADIOTHERAPY; LEUKAEMIA;
PROGNOSIS; ABNORMALITIES; CHEMOTHERAPY
AB Purpose
Therapy-related myeloid neoplasms (t-MN) represent a unique clinical syndrome occurring in patients treated with chemotherapy and/or external-beam radiation (XRT) and are characterized by poorer prognosis compared with de novo disease. XRT techniques have evolved in recent years and are associated with significantly reduced bone marrow exposure. The characteristics of post-XRT t-MN in the current era have not been studied.
Patients and Methods
We analyzed patients who developed acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) after XRT alone (47 patients) or cytotoxic chemotherapy/combined-modality therapy (C/CMT, 181 patients) and compared them with patients with de novo MDS or AML (222 patients). We estimated bone marrow exposure to radiation and compared the clinical, pathologic, and cytogenetic features and outcome of the XRT patients with the C/CMT patients and with patients with de novo MDS and AML.
Results
Patients with t-MN after XRT alone had superior overall survival (P = .006) and lower incidence of high-risk karyotypes (P = .01 for AML and < .001 for MDS) compared with patients in the C/CMT group. In contrast, there were no significant differences in survival or frequency of high-risk karyotypes between the XRT and de novo groups.
Conclusion
AML and MDS diagnosed in the past decade in patients after receiving XRT alone differ from t-MN occurring after C/CMT and share genetic features and clinical behavior with de novo AML/MDS. Our results suggest that post-XRT MDS/AML may not represent a direct consequence of radiation toxicity and warrant a therapeutic approach similar to de novo disease.

TI Phase I Study of RO4929097, a Gamma Secretase Inhibitor of Notch
Signaling, in Patients With Refractory Metastatic or Locally Advanced
Solid Tumors
SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID CANCER; ANGIOGENESIS
AB Purpose
To determine the maximum-tolerated dose (MTD) and assess safety, pharmacokinetics, pharmacodynamics, and evidence of antitumor activity of RO4929097, a gamma secretase inhibitor of Notch signaling in patients with advanced solid malignancies.
Patients and Methods
Patients received escalating doses of RO4929097 orally on two schedules: (A) 3 consecutive days per week for 2 weeks every 3 weeks; (B) 7 consecutive days every 3 weeks. To assess reversible CYP3A4 autoinduction, the expanded part of the study tested three dosing schedules: (B) as above; modified A, 3 consecutive d/wk for 3 weeks; and (C) continuous daily dosing. Positron emission tomography scans with [F-18]fluorodeoxyglucose (FDG-PET) were used to assess tumor metabolic effects.
Results
Patients on schedule A (n = 58), B (n = 47), and C (n = 5; expanded cohort) received 302 cycles of RO4929097. Common grade 1 to 2 toxicities were fatigue, thrombocytopenia, fever, rash, chills, and anorexia. Transient grade 3 hypophosphatemia (dose-limiting toxicity, one patient) and grade 3 pruritus (two patients) were observed at 27 mg and 60 mg, respectively; transient grade 3 asthenia was observed on schedule A at 80 mg (one patient). Tumor responses included one partial response in a patient with colorectal adenocarcinoma with neuroendocrine features, one mixed response (stable disease) in a patient with sarcoma, and one nearly complete FDG-PET response in a patient with melanoma. Effect on CYP3A4 induction was observed.
Conclusion
RO4929097 was well tolerated at 270 mg on schedule A and at 135 mg on schedule B; the safety of schedule C has not been fully evaluated. Further studies are warranted on the basis of a favorable safety profile and preliminary evidence of clinical antitumor activity.

TI Efficacy and Safety of Regorafenib in Patients With Metastatic and/or
Unresectable GI Stromal Tumor After Failure of Imatinib and Sunitinib: A
Multicenter Phase II Trial
SO JOURNAL OF CLINICAL ONCOLOGY
LA English
DT Article
ID RESISTANCE; MECHANISMS; KIT; MESYLATE
AB Purpose
Metastatic GI stromal tumor (GIST) is a life-threatening disease with no therapy of proven efficacy after failure of imatinib and sunitinib. Regorafenib is a structurally unique inhibitor of multiple cancer-associated kinases, including KIT and platelet-derived growth factor receptor (PDGFR), with broad-spectrum anticancer activity in preclinical and early-phase trials. Because KIT and PDGFR-alpha remain drivers of GIST after resistance to imatinib and sunitinib, we performed a multicenter single-stage phase II trial of regorafenib in patients with advanced GIST after failure of at least imatinib and sunitinib.
Patients and Methods
Patients received regorafenib orally, 160 mg daily, on days 1 to 21 of a 28-day cycle. Disease assessment was performed every two cycles per RECIST 1.1. Primary end point was clinical benefit rate (CBR), defined as objective responses (ie, complete or partial response [PR] as well as stable disease [SD] >= 16 weeks). Serial tumor biopsies were obtained from consenting patients whenever possible.

From February to December 2010, 34 patients were enrolled at four US centers. As of July 28, 2011, 33 patients had received at least two cycles of regorafenib (range, two to 17 cycles). CBR was 79% (95% CI, 61% to 91%). Four patients achieved PR, and 22 exhibited SD >= 16 weeks. Median progression-free survival was 10.0 months. The most common grade 3 toxicities were hypertension and hand-foot-skin reaction.
Conclusion
Regorafenib has significant activity in patients with advanced GIST after failure of both imatinib and sunitinib. A phase III trial of regorafenib versus placebo is ongoing to define more fully the safety and efficacy of regorafenib in this setting.

AB We evaluated the quality of care provided to older patients with complex needs in a dual-eligible, community-based Medicare Special Needs Plan that used a nurse care manager model. Care provided by physicians was substantially supplemented by nurse care managers, as measured by Assessing Care of Vulnerable Elders quality indicators. We describe selected nurse care manager activities for six geriatric conditions (falls, dementia, depression, nutrition, urinary incontinence, and end-of-life care) during provision of patient care coordination and management for patients in the highest decile of clinical complexity. We identify areas of high nurse performance (i.e., falls screening, functional assessment, behavioral interventions for dementia problems, advance care planning) and areas of potential missed opportunities (i.e., follow up for new memory problems, targeted dementia counseling, nutrition, and behavioral approaches to urinary incontinence). Increasing the collaborative interaction between nurses providing care in this model and physicians has the potential to enhance nurses' contributions to primary care for vulnerable older adults.

AB In spite of an initially proposed role as a costimulatory molecule for CD69, in vivo studies showed it as a regulator of immune responses and lymphocyte egress. We found constitutive CD69 expression by T cell subsets and pDC. We examined a possible effect of CD69 on T cell proliferation using transfer models and in vitro assays. In mice locally expressing or receiving antigen, anti-CD692.2 treatment did not affect the proliferation of antigen-specific transgenic T cells in ADLN, although we observed the presence of proliferated T cells in non-ADLN and spleen. This was not affected by FTY720 treatment and thus, not contributed by increased egress of proliferated lymphocytes from ADLN. In the absence of antigen, anti-CD69 2.2 treatment induced bystander proliferation of transferred memory phenotype T cells. This proliferation was mediated by IL-2, as it was inhibited by anti-IL-2 or anti-CD25 antibodies in vitro and by anti-CD25 antibodies in vivo. It was also dependent on CD69 expression by donor T cells and recipient cells. CD69 targeting on T cells enhanced IL-2-mediated proliferation and CD25 expression. However, it did not lead to increased early IL-2 production by T cells. No T cell subset was found to be specifically required in the recipient. Instead, CD69 targeting on pDC induced their expression of IL-2 and CD25, and pDC depletion showed that this subset was involved in the proliferation induction. These results indicate that CD69 targeting induces bystander T cell proliferation through pDC IL-2 production and T cell sensitization to IL-2 without affecting antigen-driven T cell proliferation.

AB IFN-gamma/LPS-activated hamster (Mesocricetus auratus) macrophages express significantly less iNOS (NOS2) than activated mouse macrophages, which contributes to the hamster's susceptibility to intracellular pathogens. We determined a mechanism responsible for differences in iNOS promoter activity in hamsters and mice. The HtPP (1.2 kb) showed low basal and inducible promoter activity when compared with the mouse, and sequences within a 100-bp region (-233 to -133) of the mouse and hamster promoters influenced this activity. Moreover, within this 100 bp, we identified a smaller region (44 bp) in the mouse promoter, which recovered basal promoter activity when swapped into the hamster promoter. The mouse homolog (100-bp region) contained a cis-element for NF-IL-6 (-153/-142), which was absent in the hamster counterpart. EMSA and supershift assays revealed that the hamster sequence did not support the binding of NF-IL-6. Introduction of a functional NF-IL-6 binding sequence into the hamster promoter or its alteration in the mouse promoter revealed the critical importance of this transcription factor for full iNOS promoter activity. Furthermore, the binding of NF-IL-6 to the iNOS promoter (-153/-142) in vivo was increased in mouse cells but was reduced in hamster cells after IFN-gamma/LPS stimulation. Differences in the activity of the iNOS promoters were evident in mouse and hamster cells, so they were not merely a result of species-specific differences in transcription factors. Thus, we have identified unique DNA sequences and a critical transcription factor, NF-IL-6, which contribute to the overall basal and inducible expression of hamster iNOS. J. Leukoc.

AB Rapid detection of nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) followed by appropriate infection control procedures reduces MRSA infection and transmission. We compared the performance and workflow of two Food and Drug Administration-approved nucleic acid amplification assays, the LightCycler MRSA Advanced Test and the Xpert MRSA test, with those of directly plated culture (MRSASelect) using 1202 nasal swabs collected at three U.S. sites. The sensitivity of the LightCycler test (95.2%; 95% CI, 89.1% to 98.4%) and Xpert assay (99%; 95% CI, 94.8% to 100%) did not differ compared with that of culture; the specificity of the two assays was identical (95.5%; 95% CI, 94.1% to 96.7%) compared with culture. However, sequencing performed on 71 samples with discordant results among the three methods confirmed the presence of MRSA in 40% of samples that were positive by both molecular methods but negative by culture. Workflow analysis from all sites including batch runs revealed average hands-on sample preparation times of 1.40, 2.35, and 1.44 minutes per sample for the LightCycler, Xpert, and MRSASelect methods, respectively. Discrete event simulation analysis of workflow efficiencies revealed that the LightCycler test used less hands-on time for the assay when greater than eight batched samples were run. The high sensitivity and specificity, low hands-on time, and efficiency gains using hatching capabilities make the LightCycler test suitable for rapid batch screening of MRSA colonization.

AB BACKGROUND AND PURPOSE To determine the proper method for the normalization of spinal cord volume. MATERIALS AND METHODS A group of 34 multiple sclerosis (MS) patients (28 relapsing and 6 progressive) and 15 healthy controls had whole spinal cord 3-mm thick T2-weighted axial fast spin-echo magnetic resonance imaging (MRI) images obtained at 3T. For each participant, four volumes were measured (C2-3 volume, cervical cord volume, thoracic cord volume, and whole cord volume). The volumes were normalized by the number of slices and three potential measures of body size (intracranial volume [ICV], body mass index, and body surface area) using the proportional method. RESULTS All raw volumes and volumes normalized by number of slices or ICV were significantly lower in progressive MS patients compared to relapsing MS patients/healthy controls (P < .05). In addition, C2-3 volume and cervical cord volume were significantly correlated with Expanded Disability Status Scale score (P < .05). All regional volumes showed high intercorrelation, and normalization by the number of slices significantly increased some correlations. Regarding reliability, whole cord volume regardless of normalization technique had lower coefficient of variation than C2-3 volume. CONCLUSIONS Since normalization factor had limited impact on reliability and the ability to detect differences, normalization by the number of slices is recommended.

First published March 28, 2012; doi:10.1152/jn.00051.2012.-Activation of the medial olivocochlear (MOC) efferents attenuates cochlear gain and reduces the amplitudes of mechanical, electrical, and neural cochlear outputs. The functional roles of the MOC efferents are not fully understood, especially in humans, despite postulations that they are involved in protection against acoustic trauma, facilitation of transient-sound perception, etc. Delineating the frequency tuning properties of the MOC efferents would provide critical evidence to support or refute these postulated functional roles. By utilizing spontaneous otoacoustic emissions (SOAEs), a cochlear measure sensitive to MOC modulation, we systematically demonstrate in humans that the contralateral MOC reflex is tuned to a fixed frequency band between 500 and 1,000 Hz independent of SOAE frequency. Our results question the role of the MOC reflex in protection against acoustic trauma or facilitation of transient-sound perception.

AB Wen B, Wang GI, Dean I, Delgutte B. Time course of dynamic range adaptation in the auditory nerve. J Neurophysiol 108: 69-82, 2012. First published March 28, 2012; doi:10.1152/jn.00055.2012.-Auditory adaptation to sound-level statistics occurs as early as in the auditory nerve (AN), the first stage of neural auditory processing. In addition to firing rate adaptation characterized by a rate decrement dependent on previous spike activity, AN fibers show dynamic range adaptation, which is characterized by a shift of the rate-level function or dynamic range toward the most frequently occurring levels in a dynamic stimulus, thereby improving the precision of coding of the most common sound levels (Wen B, Wang GI, Dean I, Delgutte B. J Neurosci 29: 13797-13808, 2009). We investigated the time course of dynamic range adaptation by recording from AN fibers with a stimulus in which the sound levels periodically switch from one nonuniform level distribution to another (Dean I, Robinson BL, Harper NS, McAlpine D. J Neurosci 28: 6430-6438, 2008). Dynamic range adaptation occurred rapidly, but its exact time course was difficult to determine directly from the data because of the concomitant firing rate adaptation. To characterize the time course of dynamic range adaptation without the confound of firing rate adaptation, we developed a phenomenological "dual adaptation" model that accounts for both forms of AN adaptation. When fitted to the data, the model predicts that dynamic range adaptation occurs as rapidly as firing rate adaptation, over 100-400 ms, and the time constants of the two forms of adaptation are correlated. These findings suggest that adaptive processing in the auditory periphery in response to changes in mean sound level occurs rapidly enough to have significant impact on the coding of natural sounds.

AB Objective: Health care workers are at high risk of developing musculoskeletal symptoms and pain. This study tested the hypothesis that sleep deficiency is associated with pain, functional limitations, and physical limitations that interfere with work. Methods: Hospital patient care workers completed a survey (79% response rate) including measures of health, sociodemographic, and workplace factors. Associations of sleep deficiency with pain, work interference due to this pain, and functional limitations were determined. Results: Of 1572 respondents (90% women; mean age, 41 years), 57% reported sleep deficiency, 73% pain in last 3 months, 33% work interference, and 18% functional limitation. Sleep deficiency was associated with higher rates of pain, work interference, and functional limitation controlling for socioeconomic, individual, and workplace characteristics. Conclusions: Sleep deficiency is significantly associated with pain, functional limitation, and workplace interference, suggesting modifiable outcomes for workplace health and safety interventions.

AB Objective: To determine the impact of a video on preferences for the primary goal of care.
Design, subjects, and intervention: Consecutive subjects 65 years of age or older (n=101) admitted to two skilled nursing facilities (SNFs) were randomized to a verbal narrative (control) or a video (intervention) describing goals-of-care options. Options included: life-prolonging (i.e., cardiopulmonary resuscitation), limited (i.e., hospitalization but no cardiopulmonary resuscitation), or comfort care (i.e., symptom relief).
Main measures: Primary outcome was patients' preferences for comfort versus other options. Concordance of preferences with documentation in the medical record was also examined.
Results: Fifty-one subjects were randomized to the verbal arm and 50 to the video arm. In the verbal arm, preferences were: comfort, n=29 (57%); limited, n=4 (8%); life-prolonging, n=17 (33%); and uncertain, n=1 (2%). In the video arm, preferences were: comfort, n=40 (80%); limited, n=4 (8%); and life-prolonging, n=6 (12%). Randomization to the video was associated with greater likelihood of opting for comfort (unadjusted rate ratio, 1.4; 95% confidence interval [CI], 1.1-1.9, p=0.02). Among subjects in the verbal arm who chose comfort, 29% had a do-not-resuscitate (DNR) order (kappa statistic 0.18; 95% CI-0.02 to 0.37); 33% of subjects in the video arm choosing comfort had a DNR order (kappa statistic 0.06; 95% CI-0.09 to 0.22).
Conclusion: Subjects admitted to SNFs who viewed a video were more likely than those exposed to a verbal narrative to opt for comfort. Concordance between a preference for comfort and a DNR order was low. These findings suggest a need to improve ascertainment of patients' preferences.

ID SURFACE
AB Purpose: To measure the average number, size, shape and articular surface area of articular fracture fragments of the distal humerus using quantitative analysis of 3-dimensional computed tomography (3DCT) images.
Materials and methods: Forty-eight computed tomography scans of distal humerus fractures were analyzed with quantitative 3DCT (Q3DCT). Twenty-one patients had a capitellum and trochlea fracture, and 27 patients had bicolumnar fractures of the distal humerus. The volume and articular surface area of each articular fracture fragment were measured. A small fragment was defined of having a volume of less than 500 mm 3 or an articular surface of less than 500 mm(2).
Results: Bicolumnar fractures have a mean of 9.3 fragments, 5.4 small fragments, and 3.7 articular fragments per fracture. Trochlea and capitellum fractures have a mean of 3.6 fragments, 1.5 small fragments, and 2.3 articular fragments per fracture. For each fracture type, the number of small fragments correlated with the total number of fragments.
Conclusion: Columnar fractures had more articular fragments and more small fragments than trochlea and capitellum fractures. Level of evidence: Basic Science Study, Anatomic Study, Imaging. (C) 2012 Journal of Shoulder and Elbow Surgery Board of Trustees.

AB Objective: Despite the long recognized importance and well-documented impact of drinking patterns on health and safety, college student drinking patterns are understudied. This study used a daily-level, academic-year-long, multisite sample to identify subpopulations of college student drinking patterns and to describe how these groups differ from one another before, during, and after their first year of college. Method: Two cohorts of first-year college students (n = 588; 59% female) reported daily drinking on a biweekly basis using web-based surveys and completed surveys before and after their first year of college. Results: Cluster analyses based on time series analysis estimates of within-person drinking differences (per weekday, semester, first 6 weeks) and other descriptors of day-to-day drinking identified five drinking patterns: two low (47% and 6%), two medium (24% and 15%), and one high (8%) drinking cluster. Multinomial logistic regression analyses examined cluster differences in pre-college characteristics (i.e., demographics, alcohol outcome expectancies, alcohol problems, depression, other substance use) and first-year college experiences (i.e., academic engagement, alcohol consequences, risky drinking practices, alcohol problems, drinking during academic breaks). Low-drinking students appeared to form a relatively homogeneous group, whereas two distinct patterns were found for medium-drinking students with different weekend and Thursday drinking rates. The Thursday drinking cluster showed lower academic engagement and greater participation in risky drinking practices. Conclusions: These findings highlight quantitative and qualitative differences in day-to-day drinking patterns and suggest a link between motivational differences and drinking patterns, which may be addressed in developing tailored interventional strategies.

AB The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) allow many systemic therapy options for patients with metastatic non-small cell lung cancer (NSCLC). This analysis uses the NCCN NSCLC Outcomes Database to report on first-line therapy practice patterns and concordance with NCCN Guidelines. The analysis was limited to patients diagnosed with metastatic NSCLC between September 2006 and November 2009 at 1 of 8 participating NCCN Member Institutions. Patient characteristics, regimens used, and guidelines concordance were analyzed. Institutional variation and changes in practice over time were also measured. A total of 1717 patients were included in the analysis'. Of these, 1375 (80%) were treated with systemic therapy, most often in the form of a carboplatin-based doublet (51%) or carboplatin-based doublet with targeted therapy (17%). Overall, 76% of patients received care that was concordant with NCCN Guidelines. Among patients with good performance status (n = 167), the most common reasons for not receiving first-line therapy were that therapy was not recommended (39%) or death occurred before treatment (33%). The most common reason for receiving nonconcordant drug therapy was the administration of pemetrexed or erlotinib before its incorporation into the NCCN Guidelines for first-line therapy (53%). Most patients in this cohort received care that was concordant with NCCN Guidelines. The NSCLC Outcomes Database is a valuable resource for evaluating practice patterns and concordance with NCCN Guidelines among patients with NSCLC. (JNCCN 2012;10:847-856)

AB The inaugural NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for acute lymphoblastic leukemia (ALL) were developed as a result of meetings convened by a multi-disciplinary panel of experts in 2011. These NCCN Guidelines provide recommendations on the diagnostic evaluation and workup for ALL, risk assessment, risk-stratified treatment approaches based on the Philadelphia chromosome status and age (adults vs. adolescents/young adults), assessment of minimal residual disease, and supportive care considerations. It is recommended that patients be treated at specialized centers with expertise in the management of ALL. (JNCCN 2012;10:858-914)

TI West Nile Virus T-Cell Ligand Sequences Shared with Other Flaviviruses:
a Multitude of Variant Sequences as Potential Altered Peptide Ligands

AB Phylogenetic relatedness and cocirculation of several major human pathogen flaviviruses are recognized as a possible cause of deleterious immune responses to mixed infection or immunization and call for a greater understanding of the inter-Flavivirus protein homologies. This study focused on the identification of human leukocyte antigen (HLA)-restricted West Nile virus (WNV) T-cell ligands and characterization of their distribution in reported sequence data of WNV and other flaviviruses. H-2-deficient mice transgenic for either A2, A24, B7, DR2, DR3, or DR4 HLA alleles were immunized with overlapping peptides of the WNV proteome, and peptide-specific T-cell activation was measured by gamma interferon (IFN-gamma) enzyme-linked immunosorbent spot (ELISpot) assays. Approximately 30% (137) of the WNV proteome peptides were identified as HLA-restricted T-cell ligands. The majority of these ligands were conserved in similar to >= 88% of analyzed WNV sequences. Notably, only 51 were WNV specific, and the remaining 86, chiefly of E, NS3, and NS5, shared an identity of nine or more consecutive amino acids with sequences of 64 other flaviviruses, including several major human pathogens. Many of the shared ligands had an incidence of >50% in the analyzed sequences of one or more of six major flaviviruses. The multitude of WNV sequences shared with other flaviviruses as interspecies variants highlights the possible hazard of defective T-cell activation by altered peptide ligands in the event of dual exposure to WNV and other flaviviruses, by either infection or immunization. The data suggest the possible preferred use of sequences that are pathogen specific with minimum interspecies sequence homology for the design of Flavivirus vaccines.
