TI Self-Reported and Actual Beta-Blocker Prescribing for Heart Failure Patients: Physician Predictors SO PLOS ONE LA English DT Article ID ACUTE MYOCARDIAL-INFARCTION; PRIMARY-CARE; MEDICATION UNDERUSE; MANAGEMENT; DIAGNOSIS; OUTCOMES; ASTHMA; PRACTITIONERS; CARVEDILOL; GUIDELINES AB Background: Beta-blockers reduce mortality among patients with systolic heart failure (HF), yet primary care provider prescription rates remain low. Objective: To examine the association between primary care physician characteristics and both self-reported and actual prescription of beta-blockers among patients with systolic HF. Design: Cross-sectional survey with supplementary retrospective chart review. Participants: Primary care providers at three New York City Veterans Affairs medical centers. Measurements: Main outcomes were: 1) self-reported prescribing of beta-blockers, and 2) actual prescribing of beta-blockers among HF patients. Physician HF practice patterns and confidence levels, as well as socio-demographic and clinical characteristics, were also assessed. Results: Sixty-nine of 101 physicians (68%) completed the survey examining self-reported prescribing of beta-blockers. Physicians who served as inpatient ward attendings self-reported significantly higher rates of beta-blocker prescribing among their HF patients when compared with physicians who did not attend (78% vs. 58%; p = 0.002), as did physicians who were very confident in managing HF patients when compared with physicians who were not (82% vs. 68%; p = 0.009). Fifty-one of these 69 surveyed physicians (74%) were successfully matched to 287 HF patients for whom beta-blocker prescribing data was available. Physicians with greater self-reported rates of prescribing beta-blockers were significantly more likely to actually prescribe beta-blockers ( p = 0.02); however, no other physician characteristics were significantly associated with actual prescribing of beta-blockers among HF patients. Conclusions: Physician teaching responsibilities and confidence levels were associated with self-reported beta-blocker prescribing among their HF patients. Educational efforts focused on improving confidence levels in HF care and increasing exposure to teaching may improve beta-blocker presciption in HF patients managed in primary care.

Interestingly, the mutation of the catalytically important Glu3 (E3) residue to Gin (Q) significantly changes the free-energy surface so that oxoG can bind stably in the active site of the enzyme, Free-energy simulations with the protonated and deprotonated E3 residue further showed that the protonation of the catalytically important E3 residue plays a key role in distinguishing oxoG versus G in the active site by lowering the free energy of oxoG preferentially in the active site. The results suggest that MutM utilizes the thermodynamic recognition mechanism for stable binding of the lesion base in the active site of the enzyme in addition to kinetic discrimination at the early stage of the base extrusion for facilitated extrusion of oxoG.

Males (n = 217) 15-31 years with and without ADHD were assessed at 3 time points over 10 years into young adulthood. Subjects were stratified into Remittent ADHD. and Persistent ADHD based on the course of ADHD. Cognitive domains included: 1) overall IQ(overall IQ, block design IQ, vocabulary IQ); 2) achievement scores in reading and math and measures of executive function (Wechsler arithmetic, digit span, digit symbol, Rey-Osterrieth, Wisconsin Card Sorting Test, and the Stroop Test). Cognitive outcomes were modeled as a function of group (Controls, Remittent ADHD, and Persistent ADHD), age, group by age interaction, and any demographic confounders using linear growth-curve models. There were no significant interaction effects of group by time. Main group effects indicated that persistent and remittent ADHD groups both had significantly lower scores on all cognitive outcomes compared with controls, and these did not differ between the ADHD subgroups Psychometrically defined cognitive deficits are relatively stable into young adult years and appear to be independent of the course of ADHD. More work is needed to help define the implications of these deficits in individuals with a remitting course of ADHD. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

Subjects were derived from identically designed case-control family studies of boys and girls with ADHD and a genetic linkage study of families with children with ADHD. Caucasian probands and family members with ADHD and with available genetic data were included in this analysis (N = 563). The course of ADHD was compared in subjects with and without putative risk alleles (DRD4 7-repeat allele, DAT1 10-repeat allele, and 5HTTLPR long allele). The persistence of ADHD (full or subthreshold diagnosis in the last month) was plotted using Kaplan-Meier survival functions and tested with Cox proportional hazard models. Survival analyses revealed that by 25 years of age 76% of subjects with a DRD4 7-repeat allele were estimated to have significantly more persistent ADHD compared with 66% of subjects without the risk allele. In contrast, there were no significant associations between the course of ADHD and the DAT1 10-repeat allele (P = 0.94) and 5HTTLPR long allele. Our findings suggest that the DRD4 7-repeat allele is associated with a more persistent course of ADHD. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

The present study evaluated item-level tests of scaling assumptions of the PAI-SF using a large (N = 503) clinical sample of participants who completed the PAI during their admission to a psychiatric inpatient unit. Internal consistency reliability was high across scales. and tests of item-scale convergence and discrimination generally confirmed hypothesized item groupings. Scale-level correlations supported unique variance being measured by each scale. Finally. agreement between the PAI short- and full-form scales was found to be high. The results are discussed with regards to scale interpretation. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

We used H-1 spectroscopy to verify whether MDD patients differ from healthy controls (HQ in metabolite levels in this brain area. Thirty-seven unmedicated DSM-IV MDD patients were compared with 40 HC. Subjects underwent a short echo-time H-1 spectroscopy examination at 1.5 T, with an 8-cm(3) single voxel placed in the left DLPFC. Reliable absolute metabolite levels of N-acetyl aspartate (NAA), phosphocreatine plus creatine (PCr+Cr), choline-containing compounds (GPC+PC), myo-inositol, glutamate plus glutamine (Glu+Gln), and glutamate were obtained using the unsuppressed water signal as an internal reference. Metabolite levels in the left DLPFC did not statistically differ between MDD patients and HC. We found an interaction between gender and diagnosis on PCr+Cr levels. Male MDD patients presented lower levels of PCr+Cr than male HC, and female MDD patients presented higher levels of PCr+Cr than female HC. Moreover, length of illness was inversely correlated with NAA levels. These findings suggest that there is not an effect of diagnosis on the left DLPFC neurochemistry. Possible effects of gender on PCr+Cr levels of MDD patients need to be further investigated. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

Hsu, John TI Perspectives from deductible plan enrollees: plan knowledge and anticipated care-seeking changes SO BMC HEALTH SERVICES RESEARCH LA English DT Article ID DIRECTED HEALTH PLANS; SERVICES AB Background: Consumer directed health care proposes that patients will engage as informed consumers of health care services by sharing in more of their medical costs, often through deductibles. We examined knowledge of deductible plan details among new enrollees, as well as anticipated care-seeking changes in response to the deductible. Methods: In a large integrated delivery system with a range of deductible-based health plans which varied in services included or exempted from deductible, we conducted a mixed-method, cross-sectional telephone interview study. Results: Among 458 adults newly enrolled in a deductible plan (71% response rate), 51% knew they had a deductible, 26% knew the deductible amount, and 6% knew which medical services were included or exempted from their deductible. After adjusting for respondent characteristics, those with more deductible-applicable services and those with lower self-reported health status were significantly more likely to know they had a deductible. Among those who knew of their deductible, half anticipated that it would cause them to delay or avoid medical care, including avoiding doctor's office visits and medical tests, even services that they believed were medically necessary. Many expressed concern about their costs, anticipating the inability to afford care and expressing the desire to change plans. Conclusion: Early in their experience with a deductible, patients had limited awareness of the deductible and little knowledge of the details. Many who knew of the deductible reported that it would cause them to delay or avoid seeking care and were concerned about their healthcare costs.

TI A Broadly Conserved Pathway Generates 3 ' UTR-Directed Primary piRNAs SO CURRENT BIOLOGY LA English DT Article ID PIWI-INTERACTING RNAS; DROSOPHILA-MELANOGASTER; ARGININE METHYLATION; ENDOGENOUS SIRNAS; DNA METHYLATION; FAMILY-MEMBERS; SOMATIC-CELLS; HUMAN GENOME; BRAIN-TUMOR; TRAFFIC-JAM AB Background: Piwi-interacting RNAs (piRNAs) are similar to 24-30 nucleotide regulatory RNAs that are abundant in animal gonads and early embryos. The best-characterized piRNAs mediate a conserved pathway that restricts transposable elements, and these frequently engage a "ping-pong" amplification loop. Certain stages of mammalian testis also accumulate abundant piRNAs of unknown function, which derive from noncoding RNAs that are depleted in transposable element content and do not engage in ping-pong. Results: We report that the 3' untranslated regions (3'UTRs) of an extensive set of messenger RNAs (mRNAs) are processed into piRNAs in Drosophila ovaries, murine testes, and Xenopus eggs. Analysis of different mutants and Piwi-class immunoprecipitates indicates that their biogenesis depends on primary piRNA components, but not most ping-pong components. Several observations suggest that mRNAs are actively selected for piRNA production for regulatory purposes. First, genic piRNAs do not accumulate in proportion to the level of their host transcripts, and many highly expressed transcripts lack piRNAs. Second, piRNA-producing mRNAs in Drosophila and mouse are enriched for specific gene ontology categories distinct from those of simply abundant transcripts. Third, the protein output of traffic jam, whose 3'UTR generates abundant piRNAs, is increased in piwi mutant follicle clones. Conclusions: We reveal a conserved primary piRNA pathway that selects and metabolizes the 3'UTRs of a broad set of cellular transcripts, probably for regulatory purposes. These findings strongly increase the breadth of Argonaute-mediated small RNA systems in metazoans.

Significant progress in understanding the pathophysiology of this disease has occurred in recent years, largely aided by the development of relevant animal models. Von Recklinghausen neurofibromatosis is caused by mutations in the NF1 gene, which encodes neurofibromin, a large protein that modulates the activity of Ras. Here, we describe the identification and characterization of zebrafish nf1a and nf1b, orthologues of NF1, and show neural crest and cardiovascular defects resulting from morpholino knockdown, including vascular and cardiac valvular abnormalities. Development of a zebrafish model of von Recklinghausen neurofibromatosis will allow for structure-function analysis and genetic screens in this tractable vertebrate system.

TI PGC-1 alpha negatively regulates hepatic FGF21 expression by modulating the heme/Rev-Erb alpha axis SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE liver; metabolism; diabetes; coactivator; fasting ID TRANSCRIPTIONAL COACTIVATOR PGC-1; IMPROVES INSULIN SENSITIVITY; PPAR-ALPHA; METABOLIC SYNDROME; ENERGY-EXPENDITURE; GLUCOSE-TOLERANCE; NUCLEAR RECEPTORS; FASTING RESPONSE; GAMMA; GLUCONEOGENESIS AB FGF21 is a hormone produced in liver and fat that dramatically improves peripheral insulin sensitivity and lipid metabolism. We show here that obese mice with genetically reduced levels of a key hepatic transcriptional coactivator, PGC-1 alpha, have improved whole-body insulin sensitivity with increased levels of hepatic and circulating FGF21. Gain-and loss-of-function studies in primary mouse hepatocytes show that hepatic FGF21 levels are regulated by the expression of PGC-1 alpha. Importantly, PGC-1 alpha-mediated reduction of FGF21 expression is dependent on Rev-Erb alpha and the expression of ALAS-1. ALAS-1 is a PGC-1 alpha target gene and the rate-limiting enzyme in the synthesis of heme, a ligand for Rev-Erb alpha. Modulation of intracellular heme levels mimics the effect of PGC-1 alpha on FGF21 expression, and inhibition of heme biosynthesis completely abrogates the down-regulation of FGF21 in response to PGC-1 alpha. Thus, PGC-1 alpha can impact hepatic and systemic metabolism by regulating the levels of a nuclear receptor ligand.

TI Mortality and drug exposure in a 5-year cohort of patients with chronic liver disease SO SWISS MEDICAL WEEKLY LA English DT Article DE chronic liver disease; cirrhosis; drug exposure; mortality; MELD score; ambulatory; hospitalised; tertiary referral hospital; secondary referral hospital ID RANDOMIZED CONTROLLED-TRIALS; NONSTEROIDAL ANTIINFLAMMATORY DRUGS; STATIN THERAPY; UNITED-STATES; MODEL; INJURY; FAILURE; TRANSPLANTATION; HEPATOTOXICITY; METAANALYSIS AB Background: Chronic liver diseases are common in the general population. Drug treatment in this group may be challenging, as many drugs are hepatically metabolised and hepatotoxic. Objective: We aimed to assess the mortality of patients with chronic liver disease according to specific drug exposures and the three laboratory parameters creatinine, bilirubin and International Normalised Ratio (INR). Methods: We conducted a multicentre, 5-year retrospective cohort study in two tertiary university referral hospitals and a secondary referral hospital, using a research database to evaluate the crude and adjusted mortality. Results: Of 1159 362 individual patients 1.7% (n = 20 158) had chronic liver disease and in this group 36.8% had unspecified chronic non-alcoholic liver disease, 30.1% chronic hepatitis C and 11.9% cirrhosis of die liver. 8.4% of patients presented a diagnosis associated with alcohol. The 4-year survival rates were significantly higher in the group with the most normal laboratory values (94.3%) versus 34.5% in the group with elevated parameters (p < 0.001). Overall, drug exposure was not associated with higher mortality; in adjusted multivariate analysis the hazard ratio for anti-cancer drugs was 2.69 (95% CI 1.32-5.46). Of individual drugs, mortality hazard ratios for amiodarone, morphine oral, acetazolamide, sirolimus and lamivudine were 2.46 (95% CI 1.68-3.61), 2.26 (95% CI 1.78-2.86), 2.10 (95% CI 1.19-3.70), 1.81 (95% CI 1.02-3.21) and 1.72 (95% CI 1.17-2.53) respectively. Conclusions: Drug exposure In general was not associated with higher mortality except for a few categories. Mortality in patients with chronic liver disease was high and is associated with simple laboratory values.

How this process is coordinated in the embryonic spinal cord is poorly understood. Here, we demonstrate that during the N/G fate switch in the ventral spinal cord (vSC) SOX1 links the function of neural patterning and Notch signalling. We show that, SOX1 expression in the vSC is regulated by PAX6, NKX2.2 and Notch signalling in a domain-specific manner. We further show that SOX1 regulates the expression of Hes1 and that loss of Sox1 leads to enhanced production of oligodendrocyte precursors from the pMN. Finally, we show that Notch signalling functions upstream of SOX1 during this fate switch and is independently required for the acquisition of the glial fate per se by regulating Nuclear Factor I A expression in a PAX6/SOX1/HES1/HES5-independent manner. These data integrate functional roles of neural patterning factors, Notch signalling and SOX1 during gliogenesis. (C) 2009 Elsevier Inc. All rights reserved.

The Alcs express in neurons dominantly and largely colocalize with the Alzheimer amyloid precursor protein (APP) in the brain. Alcs and APP show an identical function as a cargo receptor of kinesin-1. Moreover, proteolytic processing of Alc proteins appears highly similar to that of APP. We found that APP alpha-secretases ADAM 10 and ADAM 17 primarily cleave Alc proteins and trigger the subsequent secondary intramembranous cleavage of Alc C-terminal fragments by a presenilin-dependent gamma-secretase complex, thereby generating "APP p3-like" and non-aggregative Alc peptides (p3-Alcs). Wedetermined the complete amino acid sequence of p3-Alc(alpha), p3-Alc(beta), and p3-Alc(gamma), whose major species comprise 35, 37, and 31 amino acids, respectively, in human cerebrospinal fluid. We demonstrate here that variant p3-Alc C termini are modulated by FAD-linked presenilin 1 mutations increasing minor beta-amyloid species A beta 42, and these mutations alter the level of minor p3-Alc species. However, the magnitudes of C-terminal alteration of p3-Alc(alpha), p3-Alc(beta), and p3-Alc(gamma) were not equivalent, suggesting that one type of gamma-secretase dysfunction does not appear in the phenotype equivalently in the cleavage of type I membrane proteins. Because these C-terminal alterations are detectable in human cerebrospinal fluid, the use of a substrate panel, including Alcs and APP, may be effective to detect gamma-secretase dysfunction in the prepathogenic state of Alzheimer disease subjects.

We have shown that these two chemokines are activated by the mitogen-activated protein kinases (MAPKs) extracellular signal-regulated kinase (ERK) and p38 for IL-8, and Jun-terminal kinase (JNK) for MCP-1. It is also well established that transcription of each of these chemokines is tightly controlled by the nuclear factor kappa B (NF kappa B) transcription factor family. Therefore, we sought to better understand the differential regulation of chemokine expression by NF kappa B in adenoviral infection of the cornea. Methods: Primary keratocytes derived from human donor corneas were treated with signaling inhibitors and small interfering RNA specific to MAPKs, and infected with adenovirus for different time periods before analysis. Activation of specific NF kappa B subunits was analyzed by western blot, confocal microscopy, electromobility shift assay, and chromatin immunoprecipitation, and chemokine expression was quantified by enzyme-linked immunosorbent assay. Results: Upon adenoviral infection, NF kappa B p65, p50, and cREL subunits translocate to the nucleus. This translocation is blocked by inhibitors of specific MAPK signaling pathways. Confocal microscopy showed that inhibitors of the p38, JNK, and ERK pathways differentially inhibited NF kappa B nuclear translocation, while PP2, an inhibitor of Src family kinases, completely inhibited NF kappa B nuclear translocation. Western blot analysis revealed that activation of specific NF kappa B subunits was time dependent following infection. Chromatin immunoprecipitation experiments indicated that binding of NF kappa B p65 and p50 subunits to the IL-8 promoter upon viral infection was differentially reduced by chemical inhibitors of MAPKs. Electromobility shift assay and luciferase assay analysis revealed that transactivation of IL-8 occurred with binding by the NF kappa B p65 homodimer or NF kappa B p65/p50 heterodimer as early as 1 h post infection, whereas MCP-1 expression was dependent upon the NF kappa B cREL but not the p65 subunit, and occurred 4 h after IL-8 induction. Finally, knockdown of NF kappa B p65 by short interfering RNA abrogated IL-8 but not MCP-1 expression after adenoviral infection. Conclusion: The kinetics of NF kappa B subunit activation are partly responsible for the observed pattern of acute inflammation in the adenoviral-infected cornea. MAPKs differentially regulate chemokine expression in adenoviral keratitis by differential and time-dependent activation of specific NF kappa B subunits.

TI Identification of a myeloid committed progenitor as the cancer-initiating cell in acute promyelocytic leukemia SO BLOOD LA English DT Article ID PML-RAR-ALPHA; BINDING-PROTEIN-ALPHA; GENE-EXPRESSION PROFILES; HEMATOPOIETIC STEM-CELLS; TRANS-RETINOIC ACID; FACTOR-C/EBP-ALPHA; TRANSCRIPTION FACTOR; PML/RAR-ALPHA; GRANULOCYTIC DIFFERENTIATION; CHROMOSOMAL-ABNORMALITIES AB Acute promyelocytic leukemia (APL) is characterized by a block in differentiation and accumulation of promyelocytes in the bone marrow and blood. The majority of APL patients harbor the t(15: 17) translocation leading to expression of the fusion protein promyelocytic-retinoic acid receptor alpha. Treatment with retinoic acid leads to degradation of promyelocytic-retinoic acid receptor alpha protein and disappearance of leukemic cells; however, 30% of APL patients relapse after treatment. One potential mechanism for relapse is the persistence of cancer "stem" cells in hematopoietic organs after treatment. Using a novel sorting strategy we developed to isolate murine myeloid cells at distinct stages of differentiation, we identified a population of committed myeloid cells (CD34(+), c-kit(+), Fc gamma RIII/II(+), Gr1(int)) that accumulates in the spleen and bone marrow in a murine model of APL. We observed that these cells are capable of efficiently generating leukemia in recipient mice, demonstrating that this population represents the APL cancer-initiating cell. These cells down-regulate the transcription factor CCAAT/enhancer binding protein alpha (C/EBP alpha) possibly through a methylation-dependent mechanism, indicating that C/EBP alpha deregulation contributes to transformation of APL cancer-initiating cells. Our findings provide further understanding of the biology of APL by demonstrating that a committed transformed progenitor can initiate and propagate the disease.

A reasonable goal of MM treatment in younger "transplant eligible" patients is to initiate therapy with a target goal of durable complete remission, and the anticipated consequence of long-term disease control (and a potential "operational cure" in some). To achieve this goal we recommend induction therapy with multi-agent combination chemotherapies (usually selected from bortezomib, lenalidomide, thalidomide, cyclophosphamide, and corticosteriods) which when employed together elicit frequent, rapid, and deep responses. We recommend consolidation with high-dose melphalan and autologous stem cell transplantation in the majority of patients willing and able to undergo this procedure and subsequent maintenance therapy in those failing to achieve a complete response or at high risk for early relapse based on prognostic, genetically defined risk factors. Defining genetic risk for early relapse is therefore an important aspect of early diagnostic testing and attention to minimizing expected toxicities once therapy begins is critical in ensuring the efficacy of modern combination therapy approaches. When access to newer drugs is restricted participation in clinical trials should be pursued. (Blood. 2009; 114: 5436-5443) C1 [Stewart, A. Keith] Mayo Clin Arizona, Scottsdale, AZ 85259 USA.

A hallmark feature of this process is the generation of an elaborate system of branched protrusions called proplatelets. We recently identified RanBP10 as a tubulin-binding protein that is concentrated along polymerized micro-tubules in mature megakaryocytes. RanBP10 depletion in vitro caused the disturbance of polymerized filaments. Here we study the function of RanBP10 in vivo by generating deficient mice using a gene-trap approach. Mutant mice show normal platelet counts, and fetal liver-derived megakaryocytes reveal only slightly reduced proplatelet formation. However, ultrastructural analysis unveiled a significantly increased geometric axis ratio for resting platelets, and many platelets exhibited disorders in microtubule filament numbers and localization. Mutant mice showed a markedly prolonged bleeding time. Granule release, a process that depends on internal contraction of the microtubule marginal coil, also was reduced. Flow cytometry analysis revealed reduced expression of CD62P and CD63 after PAR4-peptide stimulation. These data suggest that RanBP10 plays an essential role in hemostasis and in maintaining microtubule dynamics with respect to both platelet shape and function.

TI The IFITM Proteins Mediate Cellular Resistance to Influenza A H1N1 Virus, West Nile Virus, and Dengue Virus SO CELL LA English DT Article ID SACCHAROMYCES-CEREVISIAE; RNA INTERFERENCE; GENE FAMILY; CELLS; ENDOCYTOSIS; EXPRESSION; SCREEN; TRANSCRIPTION; COMPLEXES; INFECTION AB Influenza viruses exploit host cell machinery to replicate, resulting in epidemics of respiratory illness. In turn, the host expresses antiviral restriction factors to defend against infection. To find host cell modifiers of influenza A H1N1 viral infection, we used a functional genomic screen and identified over 120 influenza A virus-dependency factors with roles in endosomal acidification, vesicular trafficking, mitochondrial metabolism, and RNA splicing. We discovered that the interferon-inducible transmembrane proteins IFITM1, 2, and 3 restrict an early step in influenza A viral replication. The IFITM proteins confer basal resistance to influenza A virus but are also inducible by interferons type I and II and are critical for interferon's virustatic actions. Further characterization revealed that the IFITM proteins inhibit the early replication of flaviviruses, including dengue virus and West Nile virus. Collectively this work identifies a family of antiviral restriction factors that mediate cellular innate immunity to at least three major human pathogens.

Here, we present a systematic strategy to elucidate the dynamic interactions between H1N1 influenza and its human host. A combination of yeast two-hybrid analysis and genome-wide expression profiling implicated hundreds of human factors in mediating viral-host interactions. These factors were then examined functionally through depletion analyses in primary lung cells. The resulting data point to potential roles for some unanticipated host and viral proteins in viral infection and the host response, including a network of RNA-binding proteins, components of WNT signaling, and viral polymerase subunits. This multilayered approach provides a comprehensive and unbiased physical and regulatory model of influenza-host interactions and demonstrates a general strategy for uncovering complex host-pathogen relationships.

The mechanisms controlling the activity and recruitment of PRC2 are largely unknown. Here we demonstrate that the founding member of the Jumonji family, JMJ (JUMONJI or JARID2), is associated with PRC2, colocalizes with PRC2 and H3K27me3 on chromatin, and modulates PRC2 function. In vitro JMJ inhibits PRC2 methyltransferase activity, consistent with increased H3K27me3 marks at PRC2 targets in Jmj(-/-) ESCs. Paradoxically, JMJ is required for efficient binding of PRC2, indicating that the interplay of PRC2 and JMJ fine-tunes deposition of the H3K27me3 mark. During differentiation, activation of genes marked by H3K27me3 and lineage commitments are delayed in Jmj(-/-) ESCs. Our results demonstrate that dynamic regulation of Polycomb complex activity orchestrated by JMJ balances self-renewal and differentiation, highlighting the involvement of chromatin dynamics in cell-fate transitions.

TI Complex landscapes of somatic rearrangement in human breast cancer genomes SO NATURE LA English DT Article ID TANDEM DUPLICATION; MYELOID-LEUKEMIA; COPY NUMBER; FUSION GENE; PATTERNS; TRANSLOCATIONS; IDENTIFICATION; ABERRATIONS; ETV6-NTRK3; MUTATION AB Multiple somatic rearrangements are often found in cancer genomes; however, the underlying processes of rearrangement and their contribution to cancer development are poorly characterized. Here we use a paired-end sequencing strategy to identify somatic rearrangements in breast cancer genomes. There are more rearrangements in some breast cancers than previously appreciated. Rearrangements are more frequent over gene footprints and most are intrachromosomal. Multiple rearrangement architectures are present, but tandem duplications are particularly common in some cancers, perhaps reflecting a specific defect in DNA maintenance. Short overlapping sequences at most rearrangement junctions indicate that these have been mediated by non-homologous end-joining DNA repair, although varying sequence patterns indicate that multiple processes of this type are operative. Several expressed in-frame fusion genes were identified but none was recurrent. The study provides a new perspective on cancer genomes, highlighting the diversity of somatic rearrangements and their potential contribution to cancer development.

TI Novel mutant-selective EGFR kinase inhibitors against EGFR T790M SO NATURE LA English DT Article ID CELL LUNG-CANCER; PAN-ERBB INHIBITOR; TYROSINE KINASE; RESISTANCE; GEFITINIB; MUTATION; SENSITIVITY; DASATINIB; NILOTINIB; IMATINIB AB The clinical efficacy of epidermal growth factor receptor ( EGFR) kinase inhibitors in EGFR-mutant non-small-cell lung cancer (NSCLC) is limited by the development of drug-resistance mutations, including the gatekeeper T790M mutation(1-3). Strategies targeting EGFR T790M with irreversible inhibitors have had limited success and are associated with toxicity due to concurrent inhibition of wild-type EGFR(4,5). All current EGFR inhibitors possess a structurally related quinazoline-based core scaffold and were identified as ATP-competitive inhibitors of wild-type EGFR. Here we identify a covalent pyrimidine EGFR inhibitor by screening an irreversible kinase inhibitor library specifically against EGFR T790M. These agents are 30- to 100-fold more potent against EGFR T790M, and up to 100-fold less potent against wildtype EGFR, than quinazoline-based EGFR inhibitors in vitro. They are also effective in murine models of lung cancer driven by EGFR T790M. Co-crystallization studies reveal a structural basis for the increased potency and mutant selectivity of these agents. These mutant-selective irreversible EGFR kinase inhibitors may be clinically more effective and better tolerated than quinazoline-based inhibitors. Our findings demonstrate that functional pharmacological screens against clinically important mutant kinases represent a powerful strategy to identify new classes of mutant-selective kinase inhibitors.

The ensuing excess opening of cGMP-gated cation channels causes intracellular calcium to rise to toxic levels. The Y99C mutation in guanylate cyclase-activating protein 1 (GCAP1) has been shown to act this way. We determined whether prolonged light exposure, which lowers cGMP levels through activation of phototransduction, might protect photoreceptors in a line of transgenic mice carrying the GCAP1-Y99C. Methodology/Principal Findings: We reared cohorts of GCAP1-Y99C transgenic mice under standard cyclic, constant dark and constant light conditions. Mouse eyes were analyzed by histology and by immunofluorescence for GFAP upregulation, a non-specific marker for photoreceptor degeneration. Full-field electroretinograms (ERGs) were recorded to assess retinal function. Consistent with our hypothesis, constant darkness accelerated disease, while continuous lighting arrested photoreceptor degeneration. Conclusions/Significance: In contrast to most forms of retinal degeneration, which are exacerbated by increased exposure to ambient light, a subset with mutations that cause overly active guanylyl cyclase and high intracellular calcium benefitted from prolonged light exposure. These findings may have therapeutic implications for patients with these types of genetic defects.

Its role in trauma patients, however, is controversial. This review discusses the benefits and complications of induced hypothermia--emphasizing the current state of knowledge and potential applications in bleeding patients. Extensive pre-clinical data suggest that in advanced stages of shock, rapid cooling can protect cells during ischemia and reperfusion, decrease organ damage, and improve survival. Yet hypothermia is a double edged sword; unless carefully managed, its induction can be associated with a number of complications. Appropriate patient selection requires a thorough understanding of the pre-clinical literature. Clinicians must also appreciate the enormous influence that temperature modulation exerts on various cellular mechanisms. This manuscript aims to provide a balanced view of the published literature on this topic. While many of the advantageous molecular and physiological effects of induced hypothermia have been outlined in animal models, rigorous clinical investigations are needed to translate these promising findings into clinical practice.

TI Depression and post-traumatic stress disorder among Haitian immigrant students: implications for access to mental health services and educational programming SO BMC PUBLIC HEALTH LA English DT Article ID REFUGEE CHILDREN; ADOLESCENT REFUGEES; ALCOHOL-USE; PSYCHOLOGICAL DISTRESS; BLACK-ADOLESCENTS; AFRICAN-AMERICAN; RACIAL MISTRUST; TRAUMA; WAR; BEHAVIORS AB Background: Previous studies of Haitian immigrant and refugee youth have emphasized "externalizing" behaviors, such as substance use, high risk sexual behavior, and delinquency, with very little information available on "internalizing" symptoms, such as depression and anxiety. Analyzing stressors and "internalizing" symptoms offers a more balanced picture of the type of social and mental health services that may be needed for this population. The present study aims to: 1) estimate the prevalence of depression and post-traumatic stress disorder (PTSD) among Haitian immigrant students; and 2) examine factors associated with depression and PTSD to identify potential areas of intervention that may enhance psychosocial health outcomes among immigrant youth from Haiti in the U. S. Methods: A stratified random sample of Haitian immigrant students enrolled in Boston public high schools was selected for participation; 84% agreed to be interviewed with a standardized questionnaire. Diagnosis of depression and PTSD was ascertained using the best estimate diagnosis method. Results: The prevalence estimates of depression and PTSD were 14.0% and 11.6%; 7.9% suffered from comorbid PTSD and depression. Multivariate logistic regression demonstrated factors most strongly associated with depression ( history of father's death, self-report of schoolwork not going well, not spending time with friends) and PTSD (concern for physical safety, having many arguments with parents, history of physical abuse, and lack of safety of neighborhood). Conclusions: A significant level of depression and PTSD was observed. Stressors subsequent to immigration, such as living in an unsafe neighborhood and concern for physical safety, were associated with an increased risk of PTSD and should be considered when developing programs to assist this population. Reducing exposure to these stressors and enhancing access to social support and appropriate school-based and mental health services may improve educational attainment and psychosocial health outcomes among Haitian immigrant youth.

Reduction of nitrite to NO may occur enzymatically at low pH and oxygen tension by deoxyhemoglobin, deoxymyoglobin, xanthine oxidase, mitochondrial complexes, or NO synthase (NOS). We show that nitrite treatment, in sharp contrast with the worsening effect of NOS inhibition, significantly attenuates hypothermia, mitochondrial damage, oxidative stress and dysfunction, tissue infarction, and mortality in a mouse shock model induced by a lethal tumor necrosis factor challenge. Mechanistically, nitrite-dependent protection was not associated with inhibition of mitochondrial complex I activity, as previously demonstrated for ischemia-reperfusion, but was largely abolished in mice deficient for the soluble guanylate cyclase (sGC) alpha 1 subunit, one of the principal intracellular NO receptors and signal transducers in the cardiovasculature. Nitrite could also provide protection against toxicity induced by Gram-negative lipopolysaccharide, although higher doses were required. In conclusion, we show that nitrite can protect against toxicity in shock via sGC-dependent signaling, which may include hypoxic vasodilation necessary to maintain microcirculation and organ function, and cardioprotection.

TI HLA-B*35-Px-mediated acceleration of HIV-1 infection by increased inhibitory immunoregulatory impulses SO JOURNAL OF EXPERIMENTAL MEDICINE LA English DT Article ID CLASS-I MOLECULES; IMMUNODEFICIENCY VIRUS-REPLICATION; CD8(+) T-CELLS; MYELOMONOCYTIC CELLS; HLA; AIDS; RECEPTOR; INDIVIDUALS; RECOGNITION; PROGRESSION AB A subset of HLA-B*35 alleles, B*35-Px, are strongly associated with accelerated HIV-1 disease progression for reasons that are not understood. Interestingly, the alternative set of B*35 subtypes, B*35-PY, have no detectable impact on HIV-1 disease outcomes, even though they can present identical HIV-1 epitopes as B*35-Px molecules. Thus, the differential impact of these alleles on HIV-1 disease progression may be unrelated to interactions with HIV-1-specific CD8(+) T cells. Here, we show that the B*35-Px molecule B*3503 binds with greater affinity to immunoglobulin-like transcript 4 (ILT4), an inhibitory MHC class I receptor expressed on dendritic cells, than does the B*35-PY molecule B*3501, even though these two B*35 molecules differ by only one amino acid and present identical HIV-1 epitopes. The preferential recognition of B*3503 by ILT4 was associated with significantly stronger dendritic cell dysfunction in in vitro functional assays. Moreover, HIV-1-infected carriers of B*3503 had poor dendritic cell functional properties in ex vivo assessments when compared with carriers of the B*3501 allele. Differential interactions between HLA class I allele subtypes and immunoregulatory MHC class I receptors on dendritic cells thus provide a novel perspective for the understanding of MHC class I associations with HIV-1 disease progression and for the manipulation of host immunity against HIV-1.

TI Nfil3/E4bp4 is required for the development and maturation of NK cells in vivo SO JOURNAL OF EXPERIMENTAL MEDICINE LA English DT Article ID NATURAL-KILLER-CELL; XENOPUS-LAEVIS METAMORPHOSIS; PRO-B LYMPHOCYTES; TRANSCRIPTION FACTOR; THYROID-HORMONE; DEFICIENT MICE; E4BP4; GENE; EXPRESSION; PATHWAYS AB Nuclear factor interleukin-3 (Nfil3; also known as E4-binding protein 4) is a basic region leucine zipper transcription factor that has antiapoptotic activity in vitro under conditions of growth factor withdrawal. To study the role of Nfil3 in vivo, we generated gene-targeted Nfil3-deficient (Nfil3(-/-)) mice. Nfil3(-/-) mice were born at normal Mendelian frequency and were grossly normal and fertile. Although numbers of T cells, B cells, and natural killer (NK) T cells were normal in Nfil3(-/-) mice, a specific disruption in NK cell development resulted in severely reduced numbers of mature NK cells in the periphery. This defect was NK cell intrinsic in nature, leading to a failure to reject MHC class I-deficient cells in vivo and reductions in both interferon gamma production and cytolytic activity in vitro. Our results confirm the specific and essential requirement of Nfil3 for the development of cells of the NK lineage. C1 [Kamizono, Shintaro; Seidel, Markus G.; Look, A.

TI PD-L1 regulates the development, maintenance, and function of induced regulatory T cells SO JOURNAL OF EXPERIMENTAL MEDICINE LA English DT Article ID TRANSCRIPTION FACTOR FOXP3; PROGRAMMED DEATH-1 LIGAND-1; GASTRIC EPITHELIAL-CELLS; CUTTING EDGE; DE-NOVO; CLINICAL-SIGNIFICANCE; TUMOR-IMMUNOTHERAPY; SUPPRESSOR FUNCTION; B7-H1 EXPRESSION; IMMUNE EVASION AB Both the programmed death (PD) 1-PD-ligand (PD-L) pathway and regulatory T (T reg) cells are instrumental to the maintenance of peripheral tolerance. We demonstrate that PD-L1 has a pivotal role in regulating induced T reg (iT reg) cell development and sustaining iT reg cell function. PD-L1(-/-) antigen-presenting cells minimally convert naive CD4 T cells to iT reg cells, showing the essential role of PD-L1 for iT reg cell induction. PD-L1-coated beads induce iT reg cells in vitro, indicating that PD-L1 itself regulates iT reg cell development. Furthermore, PD-L1 enhances and sustains Foxp3 expression and the suppressive function of iT reg cells. The obligatory role for PD-L1 in controlling iT reg cell development and function in vivo is illustrated by a marked reduction in iT reg cell conversion and rapid onset of a fatal inflammatory phenotype in PD-L1(-/-)PD-L2(-/-)Rag(-/-) recipients of naive CD4 T cells. PD-L1 iT reg cell development is mediated through the down-regulation of phospho-Akt, mTOR, S6, and ERK2 and concomitant with the up-regulation of PTEN, all key signaling molecules which are critical for iT reg cell development. Thus, PD-L1 can inhibit T cell responses by promoting both the induction and maintenance of iT reg cells. These studies define a novel mechanism for iT reg cell development and function, as well as a new strategy for controlling T reg cell plasticity.

San TI VMP (Bortezomib, Melphalan, and Prednisone) Is Active and Well Tolerated in Newly Diagnosed Patients With Multiple Myeloma With Moderately Impaired Renal Function, and Results in Reversal of Renal Impairment: Cohort Analysis of the Phase III VISTA Study SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID CHRONIC KIDNEY-DISEASE; MM PATIENTS; CYSTATIN-C; FAILURE; REGIMENS; REVERSIBILITY; DEXAMETHASONE; SAFETY; PATHOGENESIS; MULTICENTER AB Purpose To assess bortezomib plus melphalan and prednisone (VMP) and melphalan and prednisone (MP) in previously untreated patients with multiple myeloma (MM) with renal impairment enrolled on the phase III VISTA study, and to evaluate renal impairment reversibility. Patients and Methods Patients received nine 6-week cycles of VMP (bortezomib 1.3 mg/m(2), melphalan 9 mg/m(2), prednisone 60 mg/m(2)) or MP. Patients with serum creatinine higher than 2 mg/dL were excluded. Results In the VMP/MP arms, 6%/4%, 27%/30%, and 67%/66% of patients had baseline glomerular filtration rate (GFR) of <= 30, 31 to 50, and higher than 50 mL/min, respectively. Response rates were higher and time to progression (TTP) and overall survival (OS) longer with VMP versus MP across renal cohorts. Response rates with VMP and TTP in both arms did not appear significantly different between patients with GFR < 50 or higher than 50 mL/min; OS appeared somewhat longer in patients with normal renal function in both arms. Renal impairment reversal (baseline GFR < 50 improving to > 60 mL/min) was seen in 49 (44%) of 111 patients receiving VMP versus 40 (34%) of 116 patients receiving MP. By multivariate analysis, younger age (< 75 years; P = .006) and less severe impairment (GFR >= 30 mL/min; P = .027) were associated with higher reversal rates. In addition, treatment with VMP approached significance (P = .07). In both arms, rates of grade 4 and 5 adverse events (AEs) and serious AEs appeared higher in patients with renal impairment; with VMP, rates of discontinuations/bortezomib dose reductions due to AEs did not appear affected. Conclusion VMP is a feasible, active, and well-tolerated treatment option for previously untreated patients with MM with moderate renal impairment, resulting in 44% renal impairment reversal.

We explored the feasibility, safety, and effectiveness of an aggressive immunochemotherapy treatment program that included autologous stem-cell transplantation (ASCT) for patients up to age 69 years with newly diagnosed MCL. Patients and Methods The primary end point was 2-year progression-free survival (PFS). A successful trial would yield a 2-year PFS of at least 50% and an event rate (early progression plus nonrelapse mortality) less than 20% at day +100 following ASCT. Seventy-eight patients were treated with two or three cycles of rituximab combined with methotrexate and augmented CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone). This treatment was followed by intensification with high doses of cytarabine and etoposide combined with rituximab and filgrastim to mobilize autologous peripheral-blood stem cells. Patients then received high doses of carmustine, etoposide, and cyclophosphamide followed by ASCT and two doses of rituximab. Results There were two nonrelapse mortalities, neither during ASCT. With a median follow-up of 4.7 years, the 2-year PFS was 76% (95% CI, 64% to 85%), and the 5-year PFS was 56% (95% CI, 43% to 68%). The 5-year overall survival was 64% (95% CI, 50% to 75%). The event rate by day +100 of ASCT was 5.1%. Conclusion The Cancer and Leukemia Group B 59909 regimen is feasible, safe, and effective in patients with newly diagnosed MCL. The incorporation of rituximab with aggressive chemotherapy and ASCT may be responsible for the encouraging outcomes demonstrated in this study, which produced results comparable to similar treatment regimens.

TI Dose-Dense Adjuvant Doxorubicin and Cyclophosphamide Is Not Associated With Frequent Short-Term Changes in Left Ventricular Ejection Fraction SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID HER2-POSITIVE BREAST-CANCER; RANDOMIZED-TRIALS; FOLLOW-UP; CHEMOTHERAPY; TRASTUZUMAB; PACLITAXEL; BEVACIZUMAB; THERAPY; SAFETY AB Purpose Doxorubicin and cyclophosphamide (AC) every 3 weeks has been associated with frequent asymptomatic declines in left ventricular ejection fraction (LVEF). Dose-dense (dd) AC followed by paclitaxel (P) is superior to the same regimen given every third week. Herein, we report the early cardiac safety of three sequential studies of ddAC alone or with bevacizumab (B). Patients and Methods Patients with HER2-positive breast cancer were treated on two trials: ddAC followed by P and trastuzumab (T) and ddAC followed by PT and lapatinib. Patients with HER2-normal breast cancer were treated with B and ddAC followed by B and nanoparticle albumin-bound P. Prospective LVEF measurement by multigated radionuclide angiography scan before and after every 2 week AC for 4 cycles and at month 6 from all three trials were aggregated to determine the early risks of cardiac dysfunction. Results From January 2005 to May 2008, 245 patients were enrolled. The median age was 47 years ( range, 27 to 75 years). Median LVEF pre-ddAC was 68% (range, 52% to 82%). LVEF post-ddAC was available in 241 patients (98%) and the median was unchanged at 68% (range, 47% to 81%). Per protocol no patients were ineligible for subsequent targeted biologic therapy based on LVEF decline post-ddAC. In addition, LVEF was available in 222 patients (92%) at 6 months, at which time the median LVEF was similar at 65% (range, 24% to 80%). Within 6 months of initiating chemotherapy, three patients (1.2%; 95% CI, 0.25% to 3.54%) developed CHF, all of whom received T. Conclusion Dose-dense AC with or without concurrent bevacizumab is not associated with frequent acute or short-term declines in LVEF. C1 Mem Sloan Kettering Canc Ctr, New York, NY 10021 USA.

TI Nodal Staging Score: A Tool to Assess Adequate Staging of Node-Negative Colon Cancer SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID COLORECTAL RESECTION SPECIMENS; LYMPH-NODES; MINIMUM NUMBER; ADJUVANT CHEMOTHERAPY; SURVIVAL; RECOMMENDATIONS; ACCURACY; RECOVERY; TRIAL AB Purpose Adequate nodal staging of colon cancer has been defined as pathologic examination of at least 12 lymph nodes. We sought to refine this definition by quantifying the likelihood that a pathologically node-negative patient has, indeed, no positive nodes. Patients and Methods Patients with stage I-III adenocarcinoma of the colon between 1994 and 2005 and had at least one lymph node pathologically examined were identified from the Surveillance, Epidemiology and End Results (SEER) database (n = 131,953). We estimated the sensitivity of the pathologic staging of locoregional spread using a beta-binomial model and developed the nodal staging score (NSS), which is the probability that a patient is correctly staged as node negative. NSS is a function of T stage and the number of examined nodes. Results The probability of missing a positive node that is in fact truly present is 29.7% if five nodes are examined, 20.0% if eight are examined, and drops to 13.6% for 12 nodes are examined. An NSS of 90% can be achieved by examining a single node for T1 and four nodes for T2 tumors. To maintain similar levels of NSS for T3, 13 nodes need to be examined and for T4 lesions, 21 nodes need to be examined. Graphical and tabular tools are provided to facilitate calculation of NSS and treatment decision making in practice. Conclusion The minimum number of examined nodes for adequate staging depends on the T stage. The score we developed indicates the adequacy of nodal staging for patients with no positive nodes and can assist clinical decision making in the patient without nodal metastasis.

TI Final Version of 2009 AJCC Melanoma Staging and Classification SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID AMERICAN JOINT COMMITTEE; PRIMARY CUTANEOUS MELANOMA; LYMPH-NODE BIOPSY; TUMOR MITOTIC RATE; PROGNOSTIC-FACTORS; METASTATIC MELANOMA; MICROSCOPIC SATELLITES; SENTINEL; SURVIVAL; SYSTEM AB Purpose To revise the staging system for cutaneous melanoma on the basis of data from an expanded American Joint Committee on Cancer (AJCC) Melanoma Staging Database. Methods The melanoma staging recommendations were made on the basis of a multivariate analysis of 30,946 patients with stages I, II, and III melanoma and 7,972 patients with stage IV melanoma to revise and clarify TNM classifications and stage grouping criteria. Results Findings and new definitions include the following: (1) in patients with localized melanoma, tumor thickness, mitotic rate (histologically defined as mitoses/mm(2)), and ulceration were the most dominant prognostic factors. (2) Mitotic rate replaces level of invasion as a primary criterion for defining T1b melanomas. (3) Among the 3,307 patients with regional metastases, components that defined the N category were the number of metastatic nodes, tumor burden, and ulceration of the primary melanoma. (4) For staging purposes, all patients with microscopic nodal metastases, regardless of extent of tumor burden, are classified as stage III. Micrometastases detected by immunohistochemistry are specifically included. (5) On the basis of a multivariate analysis of patients with distant metastases, the two dominant components in defining the M category continue to be the site of distant metastases (nonvisceral v lung v all other visceral metastatic sites) and an elevated serum lactate dehydrogenase level. Conclusion Using an evidence-based approach, revisions to the AJCC melanoma staging system have been made that reflect our improved understanding of this disease. These revisions will be formally incorporated into the seventh edition (2009) of the AJCC Cancer Staging Manual and implemented by early 2010.

TI Phase II Multicenter Trial of Maintenance Biotherapy After Induction Concurrent Biochemotherapy for Patients With Metastatic Melanoma SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID COLONY-STIMULATING-FACTOR; DOSE BOLUS INTERLEUKIN-2; INTERFERON-ALPHA; RANDOMIZED-TRIAL; SEQUENTIAL CHEMOIMMUNOTHERAPY; COOPERATIVE GROUP; ONCOLOGY-GROUP; CISPLATIN; CHEMOTHERAPY; DACARBAZINE AB Purpose Biochemotherapy improves responses in metastatic melanoma, but not overall survival, in randomized trials. We developed a maintenance biotherapy regimen after induction biochemotherapy in an attempt to improve durability of responses and overall survival. Patients and Methods One hundred thirty-three chemotherapy-naive patients with metastatic melanoma without CNS metastases were treated at 10 melanoma centers. The biochemotherapy induction regimen included cisplatin, vinblastine, dacarbazine, decrescendo interleukin-2 (IL-2), and interferon alfa-2b with granulocyte-macrophage colony-stimulating factor (GM-CSF) cytokine support. Patients not experiencing disease progression were eligible for maintenance biotherapy with low-dose IL-2 and GM-CSF followed by intermittent pulses of decrescendo IL-2 over 12 months. Patients were observed for response, progression-free survival, toxicity, and overall survival. Results The response rate to induction biochemotherapy was 44% (95% CI, 35% to 52%; complete response, 8%; partial response, 36%; stable disease, 29%). The median number of biochemotherapy cycles was four, and the median number of maintenance biotherapy cycles was five. The median progression-free survival was 9 months, and the median survival was 13.5 months. The 12-month and 24-month survival rates were 57% and 23%, respectively. Twenty percent of patients remain alive (12 without disease), with median follow-up of 30 months (95% CI, 25+ to 45+ months). Thirty-nine percent of patients developed CNS metastases. The median times to CNS progression and death were 8 months and 5 months, respectively. Conclusion Maintenance biotherapy after induction biochemotherapy seems to prolong progression-free survival and improve overall survival compared with recent multicenter trials of biochemotherapy or chemotherapy. The regimen should be studied in a randomized clinical trial in patients with advanced metastatic melanoma. CNS progression remains a formidable challenge.

TI beta-Tubulin-II Expression Strongly Predicts Outcome in Patients Receiving Induction Chemotherapy for Locally Advanced Squamous Carcinoma of the Head and Neck: A Companion Analysis of the TAX 324 Trial SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article; Proceedings Paper CT 33rd Congress of the European-Society-for-Medical-Oncology CY SEP 12-16, 2008 CL Stockholm, SWEDEN SP European Soc Med Oncol ID CELL LUNG-CANCER; S-TRANSFERASE-PI; DEPENDENT ANION CHANNEL; POOR-PROGNOSIS; IMMUNOHISTOCHEMICAL ANALYSIS; BREAST-CANCER; CISPLATIN; P53; RESISTANCE; MARKERS AB Purpose TAX 324 was a phase III trial comparing induction chemotherapy (IC) with docetaxel, cisplatin, and fluorouracil (TPF) with cisplatin and fluorouracil (PF) followed by concomitant chemoradiotherapy in locally advanced squamous cell cancer of the head and neck (LASCCHN). This study evaluates a series of tumor markers in pretreatment biopsies from that trial TAX 324 and correlates expression with survival. Methods Pretherapy biopsy specimens were available for 265 of 501 participants. Expression of a series of six markers (p53, thymidylate synthase, glutathione s-transferase pi [GST-pi], Bcl 2, beta tubulin II [beta T-2], and HER2 neu) was evaluated by immunohistochemistry. Results For patients with low beta T-II expression, median overall survival (OS) was 58.6 months (95% CI, not reached [NR]), compared with 18.2 months for patients with high beta T-II expression (95% CI, 13.11 to 30.06: hazard ratio [HR], 2.39; 95% CI, 1.67 to 3.72; P < .0001). Progression-free survival in patients with low beta T-II expression was 43.2 months (95% CI, 24.4 to NR) versus 9.8 months (95% CI, 7.06 to 18.53) for high beta T-II expression, with a HR of 1.9 (95% CI, 1.43 to 2.77; P < .0001). The predictive value of beta T-II expression was greater in the TPF versus PF arm than in the PF arm. Conclusion Increased tumor expression of beta T-II is strongly associated with adverse outcome in LASCCHN patients treated with IC, and our data suggest low expression of beta T-II may predict patients most likely to benefit from induction TPF therapy. Further, simple models which combine expression of beta T-II with a carefully defined set of additional immunohistochemical markers may have significant prognostic impact for patients with LASCCHN.

Following intramuscular injection, GDNF:TTC but not recombinant GDNF (rGDNF) produced strong GDNF immunostaining within ventral horn cells of the spinal cord. Intrathecal infusion of GDNF:TTC resulted in tissue concentrations of GDNF in lumbar spinal cord that were at least 150-fold higher than those in mice treated with rGDNF. While levels of immunoreactive choline acetyltransferase and GFR alpha-1 in lumbar cord were not altered significantly by intrathecal infusion of rGNDF, GDNF:TTC, or TTC, only rGDNF and GDNF:TTC caused significant weight loss following intracerebroventricular infusion. These studies indicate that insect cell-derived GDNF:TTC retains its bi-functional activity in mammalian CNS in vivo and improves delivery of GDNF to spinal cord following intramuscular- or intrathecal administration.

TI Using mechanistic Bayesian networks to identify downstream targets of the Sonic Hedgehog pathway SO BMC BIOINFORMATICS LA English DT Article ID SIGNALING PATHWAY; GRAPHICAL MODELS; RETINOIC ACID; GENECHIP DATA; PROBE LEVEL; SHH; CELLS; EXPRESSION; BINDING; CANCER AB Background: The topology of a biological pathway provides clues as to how a pathway operates, but rationally using this topology information with observed gene expression data remains a challenge. Results: We introduce a new general-purpose analytic method called Mechanistic Bayesian Networks (MBNs) that allows for the integration of gene expression data and known constraints within a signal or regulatory pathway to predict new downstream pathway targets. The MBN framework is implemented in an open-source Bayesian network learning package, the Python Environment for Bayesian Learning (PEBL). We demonstrate how MBNs can be used by modeling the early steps of the sonic hedgehog pathway using gene expression data from different developmental stages and genetic backgrounds in mouse. Using the MBN approach we are able to automatically identify many of the known downstream targets of the hedgehog pathway such as Gas1 and Gli1, along with a short list of likely targets such as Mig12. Conclusions: The MBN approach shown here can easily be extended to other pathways and data types to yield a more mechanistic framework for learning genetic regulatory models.

TI A practical comparison of methods for detecting transcription factor binding sites in ChIP-seq experiments SO BMC GENOMICS LA English DT Article ID RNA-POLYMERASE-II; PROTEIN-DNA INTERACTIONS; EMBRYONIC STEM-CELLS; GENOME-WIDE ANALYSIS; DISCOVERY; PATHWAYS; PROGRAM; NETWORK; ALPHA AB Background: Chromatin immunoprecipitation coupled with massively parallel sequencing (ChIP-seq) is increasingly being applied to study transcriptional regulation on a genome-wide scale. While numerous algorithms have recently been proposed for analysing the large ChIP-seq datasets, their relative merits and potential limitations remain unclear in practical applications. Results: The present study compares the state-of-the-art algorithms for detecting transcription factor binding sites in four diverse ChIP-seq datasets under a variety of practical research settings. First, we demonstrate how the biological conclusions may change dramatically when the different algorithms are applied. The reproducibility across biological replicates is then investigated as an internal validation of the detections. Finally, the predicted binding sites with each method are compared to high-scoring binding motifs as well as binding regions confirmed in independent qPCR experiments. Conclusions: In general, our results indicate that the optimal choice of the computational approach depends heavily on the dataset under analysis. In addition to revealing valuable information to the users of this technology about the characteristics of the binding site detection approaches, the systematic evaluation framework provides also a useful reference to the developers of improved algorithms for ChIP-seq data.

TI The Fanconi Anemia Pathway Promotes Replication-Dependent DNA Interstrand Cross-Link Repair SO SCIENCE LA English DT Article ID MONOUBIQUITINATED FANCD2; S-PHASE; PROTEINS AB Fanconi anemia is a human cancer predisposition syndrome caused by mutations in 13 Fanc genes. The disorder is characterized by genomic instability and cellular hypersensitivity to chemicals that generate DNA interstrand cross-links (ICLs). A central event in the activation of the Fanconi anemia pathway is the mono-ubiquitylation of the FANCI-FANCD2 complex, but how this complex confers ICL resistance remains enigmatic. Using a cell-free system, we showed that FANCI-FANCD2 is required for replication-coupled ICL repair in S phase. Removal of FANCD2 from extracts inhibits both nucleolytic incisions near the ICL and translesion DNA synthesis past the lesion. Reversal of these defects requires ubiquitylated FANCI-FANCD2. Our results show that multiple steps of the essential S-phase ICL repair mechanism fail when the Fanconi anemia pathway is compromised.

Applying gene expression microarray and proteomic methods to studies on FANCC-deficient cells we found that genes encoding proteins directly involved in ubiquitinylation are overrepresented in the signature of FA bone marrow cells and that ubiquitinylation profiles of FA-C and complemented cells were substantially different. Finding that Toll-like receptor 8 (TLR8) was one of the proteins ubiquitinylated only in mutant cells, we confirmed that TLR8 (or a TLR8-associated protein) is ubiquitinylated in mutant FA-C cells and that TNF-alpha production in mutant cells depended upon TLR8 and the canonical downstream signaling intermediates interleukin 1 receptor-associated kinase (IRAK) and I kappa B kinase-alpha/beta. FANCC-deficient THP-1 cells and macrophages from Fancc(-/-) mice overexpressed TNF-alpha in response to TLR8 agonists but not other TLR agonists. Ectopically expressed FANCC point mutants were capable of fully complementing the mitomycin-C hypersensitivity phenotype of FA-C cells but did not suppress TNF-alpha overproduction. In conclusion, FANCC suppresses TNF-alpha production in mononuclear phagocytes by suppressing TLR8 activity and this particular function of FANCC is independent of its function in protecting the genome from cross-linking agents.

TI BCL6 modulates tonic BCR signaling in diffuse large B-cell lymphomas by repressing the SYK phosphatase, PTPROt SO BLOOD LA English DT Article ID PROTEIN-TYROSINE-PHOSPHATASE; ANTIGEN RECEPTOR; EXPRESSION; GENE; SURVIVAL; PHOSPHORYLATION; PROMOTER; CLONING; TARGET AB Tonic B-cell receptor (BCR) signaling is a key survival pathway during normal B-cell ontogenesis and in a subset of diffuse large B-cell lymphomas (DLBCLs). We previously demonstrated that BCR-dependent DLBCL cell lines and primary tumors underwent apoptosis after treatment with an ATP-competitive inhibitor of the BCR-associated spleen tyrosine kinase (SYK). These "BCR-type" tumors also have more abundant expression of the transcriptional repressor, BCL6, and increased sensitivity to BCL6 inhibition. Herein, we evaluated potential connections between BCL6-mediated transcriptional repression and SYK-dependent BCR signaling. In transcriptionally profiled normal B-cell subsets (naive, germinal center, and memory B cells) and in primary DLBCLs, there were reciprocal patterns of expression of BCL6 and the SYK tyrosine phosphatase PTPROt. BCL6 repressed PTPROt transcription via a direct interaction with functional BCL6 binding sites in the PTPROt promoter. Enforced expression of BCL6 in normal naive B cells and RNAi-mediated depletion of BCL6 in germinal center B cells directly modulated PTPROt expression. In "BCR-type" DLBCLs, BCL6 depletion increased PTPROt expression and decreased phosphorylation of SYK and the downstream adaptor protein BLNK. Because BCL6 augments BCR signaling and BCL6 and SYK are both promising therapeutic targets in many DLBCLs, combined inhibition of these functionally related pathways warrants further study.

We are witnessing a powerful resurgence of this idea made possible by the availability of nearly complete genome sequences, ever improving gene annotations and interactome network maps, the development of sophisticated informatic and imaging tools, and importantly, the use of engineering and physics concepts such as control and graph theory. Alongside four other fundamental "great ideas" as suggested by Sir Paul Nurse, namely, the gene, the cell, the role of chemistry in biological processes, and evolution by natural selection, systems-level understanding of "What is Life" may materialize as one of the major ideas of biology.

Gandy, Sam TI Acute dosing of latrepirdine (Dimebon (TM)), a possible Alzheimer therapeutic, elevates extracellular amyloid-beta levels in vitro and in vivo SO MOLECULAR NEURODEGENERATION LA English DT Article ID PRECURSOR PROTEIN; SYNAPTIC PLASTICITY; COGNITIVE DEFICITS; TRANSGENIC MICE; HUMAN BRAIN; A-BETA; DISEASE; OLIGOMERS; SYNAPSES; ACCUMULATION AB Background: Recent reports suggest that latrepirdine (Dimebon T, dimebolin), a retired Russian antihistamine, improves cognitive function in aged rodents and in patients with mild to moderate Alzheimer's disease (AD). However, the mechanism(s) underlying this benefit remain elusive. AD is characterized by extracellular accumulation of the amyloid-beta (A beta) peptide in the brain, and A beta-lowering drugs are currently among the most popular anti-amyloid agents under development for the treatment of AD. In the current study, we assessed the effect of acute dosing of latrepirdine on levels of extracellular A beta using in vitro and in vivo experimental systems. Results: We evaluated extracellular levels of A beta in three experimental systems, under basal conditions and after treatment with latrepirdine. Mouse N2a neuroblastoma cells overexpressing Swedish APP were incubated for 6 hr in the presence of either vehicle or vehicle + latrepirdine (500pM-5 mu M). Synaptoneurosomes were isolated from TgCRND8 mutant APP-overexpressing transgenic mice and incubated for 0 to 10 min in the absence or presence of latrepirdine (1 mu M or 10 mu M). Drug-naive Tg2576 Swedish mutant APP overexpressing transgenic mice received a single intraperitoneal injection of either vehicle or vehicle + latrepirdine (3.5 mg/kg). Picomolar to nanomolar concentrations of acutely administered latrepirdine increased the extracellular concentration of A beta in the conditioned media from Swedish mutant APP-overexpressing N2a cells by up to 64% (p = 0.01), while a clinically relevant acute dose of latrepirdine administered i.p. led to an increase in the interstitial fluid of freely moving APP transgenic mice by up to 40% (p = 0.01). Reconstitution of membrane protein trafficking and processing is frequently inefficient, and, consistent with this interpretation, latrepirdine treatment of isolated TgCRND8 synaptoneurosomes involved higher concentrations of drug (1-10 mu M) and led to more modest increases in extracellular A beta(x-42) levels (+ 10%; p = 0.001); of note, however, was the observation that extracellular A beta(x-40) levels did not change. Conclusions: Here, we report the surprising association of acute latrepirdine dosing with elevated levels of extracellular A beta as measured in three independent neuron-related or neuron-derived systems, including the hippocampus of freely moving Tg2576 mice. Given the reported association of chronic latrepirdine treatment with improvement in cognitive function, the effects of chronic latrepirdine treatment on extracellular A beta levels must now be determined.

TI Flip-Flop-Induced Relaxation of Bending Energy: Implications for Membrane Remodeling SO BIOPHYSICAL JOURNAL LA English DT Article ID LAURDAN FLUORESCENCE; MODEL MEMBRANES; VESICLES; CURVATURE; CHOLESTEROL; PROTEINS; FISSION; PHASE; ACID; CYCLODEXTRIN AB Cellular and organellar membranes are dynamic materials that underlie many aspects of cell biology. Biological membranes have long been thought of as elastic materials with respect to bending deformations. A wealth of theory and experimentation on pure phospholipid membranes provides abundant support for this idea. However, biological membranes are not composed solely of phospholipids-they also incorporate a variety of amphiphilic molecules that undergo rapid transbilayer flip-flop. Here we describe several experimental systems that demonstrate deformation-induced molecular flip-flop. First we use a fluorescence assay to track osmotically controlled membrane deformation in single component fatty acid vesicles, and show that the relaxation of the induced bending stress is mediated by fatty acid flip-flop. We then look at two-component phospholipid/cholesterol composite vesicles. We use NMR to show that the steady-state rate of interleaflet diffusion of cholesterol is fast relative to biological membrane remodeling. We then use a Forster resonance energy transfer assay to detect the transbilayer movement of cholesterol upon deformation. We suggest that our results can be interpreted by modifying the area difference elasticity model to account for the time-dependent relaxation of bending energy. Our findings suggest that rapid interleaflet diffusion of cholesterol may play a role in membrane remodeling in vivo. We suggest that the molecular characteristics of sterols make them evolutionarily preferred mediators of stress relaxation, and that the universal presence of sterols in the membranes of eukaryotes, even at low concentrations, reflects the importance of membrane remodeling in eukaryotic cells.

TI Documentation of body mass index and control of associated risk factors in a large primary care network SO BMC HEALTH SERVICES RESEARCH LA English DT Article ID AMERICAN-DIABETES-ASSOCIATION; WEIGHT MANAGEMENT; BLOOD-PRESSURE; OBESITY; DISEASE; RECOMMENDATIONS; OVERWEIGHT; ADULTS; METAANALYSIS; CHOLESTEROL AB Background: Body mass index (BMI) will be a reportable health measure in the United States (US) through implementation of Healthcare Effectiveness Data and Information Set (HEDIS) guidelines. We evaluated current documentation of BMI, and documentation and control of associated risk factors by BMI category, based on electronic health records from a 12-clinic primary care network. Methods: We conducted a cross-sectional analysis of 79,947 active network patients greater than 18 years of age seen between 7/05-12/06. We defined BMI category as normal weight (NW, 18-24.9 kg/m(2)), overweight (OW, 25-29.9), and obese (OB, >= 30). We measured documentation (yes/no) and control (above/below) of the following three risk factors: blood pressure (BP) <= 130/<= 85 mmHg, low-density lipoprotein (LDL) <= 130 mg/dL (3.367 mmol/L), and fasting glucose <100 mg/dL (5.55 mmol/L) or casual glucose <200 mg/dL (11.1 mmol/L). Results: BMI was documented in 48,376 patients (61%, range 34-94%), distributed as 30% OB, 34% OW, and 36% NW. Documentation of all three risk factors was higher in obesity (OB = 58%, OW = 54%, NW = 41%, p for trend <0.0001), but control of all three was lower (OB = 44%, OW = 49%, NW = 62%, p = 0.0001). The presence of cardiovascular disease (CVD) or diabetes modified some associations with obesity, and OB patients with CVD or diabetes had low rates of control of all three risk factors (CVD: OB = 49%, OW = 50%, NW = 56%; diabetes: OB = 42%, OW = 47%, NW = 48%, p < 0.0001 for adiposity-CVD or diabetes interaction). Conclusions: In a large primary care network BMI documentation has been incomplete and for patients with BMI measured, risk factor control has been poorer in obese patients compared with NW, even in those with obesity and CVD or diabetes. Better knowledge of BMI could provide an opportunity for improved quality in obesity care. C1 [Rose, Stephanie A.] Univ Kentucky, Div Gen Internal Med, Lexington, KY 40536 USA.

Methods: The Tuskegee Legacy Project (TLP) Questionnaire was administered via a Random-Digit Dial (RDD) telephone survey to a stratified random sample of Black, White and PR Hispanic adults in three U.S. cities. Results: The TLP Questionnaire was administered to 1,162 adults (356 African-Americans, 313 PR Hispanics, and 493 non-Hispanic Whites) in San Juan, PR, Baltimore, MD and New York City, NY. Recall question data revealed: 1) that 89% or more of Blacks, Whites, and PR Hispanics were not able to name or definitely identify the Tuskegee Syphilis Study by giving study attributes; and, 2) that Blacks were the most likely to provide an open-ended answer that identified the Tuskegee Syphilis Study as compared to Whites and PR Hispanics (11.5% vs 6.3% vs 2.9%, respectively) (p = 0.002). Even when probed by a recognition question, only a minority of each racial/ethnic group (37.1%, 26.9%, and 8.6%, for Blacks, Whites and PR Hispanics, respectively) was able to clearly identify the TSS (p < 0.001). Conclusions: The two major implications of these findings for health disparity researchers are 1) that it is unlikely that detailed knowledge of the Tuskegee Syphilis Study has any current widespread influence on the willingness of minorities to participate in biomedical research, and 2) that caution should be applied before assuming that what community leaders 'know and are aware of' is equally 'well known' within their community constituencies.

TI c-Fos protein expression is increased in cholinergic neurons of the rodent basal forebrain during spontaneous and induced wakefulness SO BRAIN RESEARCH BULLETIN LA English DT Article DE Sleep; Wake; EEG; Rat; Stress; Acetylcholine ID REPEATED SOCIAL STRESS; EARLY GENE-EXPRESSION; RAT-BRAIN; SLEEP-DEPRIVATION; NUCLEUS BASALIS; RECOVERY SLEEP; NONCHOLINERGIC PROJECTIONS; DISCHARGE PROPERTIES; THALAMIC NUCLEI; NERVOUS-SYSTEM AB It has been proposed that cholinergic neurons of the basal forebrain (BF) may play a role in vigilance state control. Since not all vigilance states have been studied, we evaluated cholinergic neuronal activation levels across spontaneously occurring states of vigilance, as well as during sleep deprivation and recovery sleep following sleep deprivation. Sleep deprivation was performed for 2 h at the beginning of the light (inactive) period, by means of gentle sensory stimulation. In the rodent BF, we used immunohistochemical detection of the c-Fos protein as a marker for activation, combined with labeling for choline acetyl-transferase (ChAT) as a marker for cholinergic neurons. We found c-Fos activation in BF cholinergic neurons was highest in the group undergoing sleep deprivation (12.9% of cholinergic neurons), while the spontaneous wakefulness group showed a significant increase (9.2%), compared to labeling in the spontaneous sleep group (1.8%) and a sleep deprivation recovery group (0.8%). A subpopulation of cholinergic neurons expressed c-Fos during spontaneous wakefulness, when possible confounds of the sleep deprivation procedure were minimized (e.g., stress and sensory stimulation). Double-labeling in the sleep deprivation treatment group was significantly elevated in select subnuclei of the BF (medial septum/vertical limb of the diagonal band, horizontal limb of the diagonal band, and the magnocellular preoptic nucleus), when compared to spontaneous wakefulness. These findings support and provide additional confirming data of previous reports that cholinergic neurons of BF play a role in vigilance state regulation by promoting wakefulness.

Objective To relate baseline circulating leptin concentrations in a community-based sample of individuals without dementia to incident dementia and AD during follow-up and magnetic resonance imaging (MRI) measures of brain aging in survivors. Design, Setting, and Participants Prospective study of plasma leptin concentrations measured in 785 persons without dementia (mean [SD] age, 79 [5] years; 62% female), who were in the Framingham original cohort at the 22nd examination cycle (1990-1994). A subsample of 198 dementia-free survivors underwent volumetric brain MRI between 1999 and 2005, approximately 7.7 years after leptin was assayed. Two measures of brain aging, total cerebral brain volume and temporal horn volume (which is inversely related to hippocampal volume) were assessed. Main Outcome Measure Incidence of dementia and AD during follow-up until December 31, 2007. Results During a median follow-up of 8.3 years (range, 0-15.5 years), 111 participants developed incident dementia; 89 had AD. Higher leptin levels were associated with a lower risk of incident dementia and AD in multivariable models (hazard ratio per 1-SD increment in log leptin was 0.68 [95% confidence interval, 0.54-0.87] for all-cause dementia and 0.60 [95% confidence interval, 0.46-0.79] for AD). This corresponds to an absolute AD risk over a 12-year follow-up of 25% for persons in the lowest quartile (first quartile) vs 6% for persons in the fourth quartile of sex-specific leptin levels. In addition, a 1-SD elevation in plasma leptin level was associated with higher total cerebral brain volume and lower temporal horn volume, although the association of leptin level with temporal horn volume did not reach statistical significance. Conclusion Circulating leptin was associated with a reduced incidence of dementia and AD and with cerebral brain volume in asymptomatic older adults.

TI Lysyl Oxidase Activity Is Dysregulated during Impaired Alveolarization of Mouse and Human Lungs SO AMERICAN JOURNAL OF RESPIRATORY AND CRITICAL CARE MEDICINE LA English DT Article DE lung development; septation; TGF-beta; transforming growth factor ID VENTILATED PRETERM INFANTS; ELASTIN CROSS-LINKING; MESSENGER-RNA LEVELS; BRONCHOPULMONARY DYSPLASIA; PULMONARY MICROVASCULATURE; MECHANICAL VENTILATION; MOLECULAR SIGNATURE; NEONATAL MICE; NEWBORN MICE; DISEASE AB Rationale Disordered extracellular matrix production is a feature of bronchopulmonary dysplasia (BPD). The basis of this phenomenon is not understood. Objectives: To assess lysyl oxidase expression and activity in the injured developing lungs of newborn mice and of prematurely born infants with BPD or at risk for BPD. Methods: Pulmonary lysyl oxidase and elastin gene and protein expression were assessed in newborn mice breathing 21 or 85% oxygen, in patients who died with BPD or were at risk for BPD, and in control patients. Signaling by transforming growth factor (TGF-beta) was preemptively blocked in mice exposed to hyperoxia using TGF-beta-neutralizing antibodies. lysyl oxidase promoter activity was assessed using plasmids containing the lox or loxi1 promoters fused upstream of the firefly luciferase gene. Measurements and Main Results: mRNA and protein levels and activity of lysyl oxidases (Lox, LoxL1, LoxL2) were elevated in the oxygen-injured lungs of newborn mice and infants with BPD or at risk for BPD. In oxygen-injured mouse lungs, increased TGF-beta signaling drove aberrant lox, but not loxi1 or lox/2, expression. Lox expression was also increased in oxygen-injured fibroblasts and pulmonary artery smooth muscle cells. Conclusions: lysyl oxidase expression and activity are dysregulated in BPD in injured developing mouse lungs and in prematurely born infants. In developing mouse lungs, aberrant TGF-beta signaling dysregulated lysyl oxidase expression. These data support the postulate that excessive stabilization of the extracellular matrix by excessive lysyl oxidase activity might impede the normal matrix remodeling that is required for pulmonary alveolarization and thereby contribute to the pathological pulmonary features of BPD.

TI Neurobiological Basis of Failure to Recall Extinction Memory in Posttraumatic Stress Disorder SO BIOLOGICAL PSYCHIATRY LA English DT Article DE Amygdala; classical; conditioning; hippocampus; posttraumatic; magnetic resonance imaging; prefrontal cortex; stress disorders ID VENTROMEDIAL PREFRONTAL CORTEX; CHILDHOOD SEXUAL-ABUSE; SCRIPT-DRIVEN IMAGERY; ANTERIOR CINGULATE FUNCTION; CORTICOLIMBIC BLOOD-FLOW; FEAR EXTINCTION; ANXIETY DISORDER; BRAIN ACTIVATION; PTSD; AMYGDALA AB Background: A clinical characteristic of posttraumatic stress disorder (PTSD) is persistently elevated fear responses to stimuli associated with the traumatic event. The objective herein is to determine whether extinction of fear responses is impaired in PTSD and whether such impairment is related to dysfunctional activation of brain regions known to be involved in fear extinction, viz., amygdala, hippocampus, ventromedial prefrontal cortex (vmPFC), and dorsal anterior cingulate cortex (dACC). Methods: Sixteen individuals diagnosed with PTSD and 15 trauma-exposed non-PTSD control subjects underwent a 2-day fear conditioning and extinction protocol in a 3-T functional magnetic resonance imaging scanner. Conditioning and extinction training were conducted on day 1. Extinction recall (or extinction memory) test was conducted on day 2 (extinguished conditioned stimuli presented in the absence of shock). Skin conductance response (SCR) was scored throughout the experiment as an index of the conditioned response. Results: The SCR data revealed no significant differences between groups during acquisition and extinction of conditioned fear on day 1. On day 2, however, PTSD subjects showed impaired recall of extinction memory. Analysis of functional magnetic resonance imaging data showed greater amygdala activation in the PTSD group during day 1 extinction learning. During extinction recall, lesser activation in hippocampus and vmPFC and greater activation in dACC were observed in the PTSD group. The magnitude of extinction memory across all subjects was correlated with activation of hippocampus and vmPFC during extinction recall testing. Conclusions: These findings support the hypothesis that fear extinction is impaired in PTSD. They further suggest that dysfunctional activation in brain structures that mediate fear extinction learning, and especially its recall, underlie this impairment.

TI Functional Neuroimaging of Reward Circuitry Responsivity to Monetary Gains and Losses in Posttraumatic Stress Disorder SO BIOLOGICAL PSYCHIATRY LA English DT Article DE Corpus striatum; functional magnetic resonance imaging; motivation; posttraumatic; reward; stress disorders ID MESIAL PREFRONTAL CORTEX; DOPAMINE-RECEPTOR DRD2; EVENT-RELATED FMRI; DORSAL STRIATUM; INDUCED ANHEDONIA; DECISION-MAKING; ANIMAL-MODELS; LOSS AVERSION; PTSD; SYSTEM AB Background: Clinical impressions and preclinical work suggest that posttraumatic stress disorder (PTSD) might be associated with dysfunctional reward processing. To pursue this issue, we administered a validated passive-viewing monetary reward task during functional magnetic resonance imaging (fMRI) to subjects with chronic PTSD and to mentally healthy individuals. \Methods: The protocol evaluated fMRI signal changes that anticipated or accompanied monetary gains and losses under varying conditions of controlled expectation. The "expectancy phase" entailed presentation of a promising, unpromising, or intermediate Wheel of Fortune-type spinner, whereas the "outcome phase" was defined by the arrow landing on one of three sectors of that spinner, thereby determining the subjects' gain or loss for that trial. Results: Neuroimaging data from 20 PTSD and 26 healthy subjects withstood quality control procedures and were included. In voxelwise and anatomically defined region-of-interest analyses, when gains were contrasted to losses, between-group comparison revealed smaller bilateral striatal activations in the PTSD subjects. In the PTSD group, less striatal activation to gains versus losses was associated with more self-reported motivational and social deficits. Conclusions: The present data support the hypothesis that PTSD is associated with abnormal processing of monetary outcomes and that this alteration might be related to some aspects of emotional numbing.

TI Laboratory Induced Aggression: A Positron Emission Tomography Study of Aggressive Individuals with Borderline Personality Disorder SO BIOLOGICAL PSYCHIATRY LA English DT Article DE Brain imaging; emotion; Point Subtraction Aggression Paradigm; PSAP ID NONVIOLENT MALE PAROLEES; ORBITAL FRONTAL-CORTEX; GLUCOSE-METABOLISM; PSYCHOMETRIC MEASUREMENTS; IMPULSIVE AGGRESSION; BRAIN ABNORMALITIES; SPECTRUM DISORDERS; BRODMANN AREAS; RHESUS-MONKEYS; FDG-PET AB Background: Borderline personality disorder (BPD) is often associated with symptoms of impulsive aggression, which poses a threat to patients themselves and to others. Preclinical studies show that orbital frontal cortex (OFC) plays a role in regulating impulsive aggression. Prior work has found OFC dysfunction in BPD. Methods: We employed a task to provoke aggressive behavior, the Point Subtraction Aggression Paradigm (PSAP), which has never previously been used during functional brain imaging. Thirty-eight BPD patients with intermittent explosive disorder (BPD-IED) and 36 age-matched healthy control subjects (HCs) received (18)fluoro-deoxyglucose positron emission tomography ((18)FDG-PET) on two occasions with a provocation and nonprovocation version of the PSAP. Mean relative glucose metabolism was measured throughout the cortex, and difference scores (provoked - nonprovoked) were calculated. A whole brain exploratory analysis for the double difference of BPD-IED - HC for provoked - nonprovoked was also conducted. Results: BPD-IED patients were significantly more aggressive than HCs on the PSAP. BPD-IED patients also increased relative glucose metabolic rate (rGMR) in OFC and amygdala when provoked, while HCs decreased rGMR in these areas, However, HCs increased rGMR in anterior, medial, and dorsolateral prefrontal regions during provocation more than BPD-IED patients. Conclusions: Patients responded aggressively and showed heightened rGMR in emotional brain areas, including amygdala and OFC, in response to provocation but not in more dorsal brain regions associated with cognitive control of aggression. In contrast, HCs increased rGMR in dorsal regions of PFC during aggression provocation, brain regions involved in top-down cognitive control of aggression, and, more broadly, of emotion.

Compound 6 showed an ex vivo EC(50) of 10.5 mu M and in vitro selectivity for binding to the recombinant alpha A-domain of CD11b/CD18. In silico docking experiments suggest that the compounds recognized a hydrophobic cleft in the ligand-binding alpha A-domain, implying an allosteric mechanism of modulation of integrin affinity by this novel compound.

In 2008, nearly 520,000 veterans had a disability for hearing loss through the Department of Veterans Affairs (VA). Changes in eligibility for hearing aid services, along with the aging population, contributed to a greater than 300% increase in the number of hearing aids dispensed from 1996 to 2006. In 2006, the VA committed to having no wait times for patient visits while providing quality clinically-appropriate care. One approach to achieving this goal is the use of group visits as an alternative to individual visits. We sought to determine: 1) if group hearing aid fitting and follow-up visits were at least as effective as individual visits, and 2) whether group visits lead to cost savings through the six month period after the hearing aid fitting. We describe the rationale, design, and characteristics of the baseline cohort of the first randomized clinical trial to study the impact of group versus individual hearing aid fitting and follow-up visits. Methods: Participants were recruited from the VA Puget Sound Health Care System Audiology Clinic. Eligible patients had no previous hearing aid use and monaural or binaural air-conduction hearing aids were ordered at the evaluation visit. Participants were randomized to receive the hearing aid fitting and the hearing aid follow-up in an individual or group visit. The primary outcomes were hearing-related function, measured with the first module of the Effectiveness of Aural Rehabilitation (Inner EAR), and hearing aid adherence. We tracked the total cost of planned and unplanned audiology visits over the 6-month interval after the hearing aid fitting. Discussion: A cohort of 659 participants was randomized to receive group or individual hearing aid fitting and follow-up visits. Baseline demographic and self-reported health status and hearing-related measures were evenly distributed across the treatment arms. Outcomes after the 6-month follow-up period are needed to determine if group visits were as least as good as those for individual visits and will be reported in subsequent publication.

Although many risk factors for HCC are well defined, including hepatitis B virus (HBV), hepatitis C virus (HCV), and alcohol, most series have indicated that 5% to 30% of patients with HCC lack a readily identifiable risk factor for their cancer. The majority of "cryptogenic" HCC in the United States is attributed to nonalcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome. The metabolic syndrome is a constellation of problems that includes insulin resistance, obesity, hypertension, and hyperlipidemia. Increasingly, components of the metabolic syndrome are being linked to various forms of cancer with respect to both increased risk of disease and worsened outcome. In this review, the authors focused on the relation between metabolic syndrome and HCC. They investigated the increased risks of HCC among individuals with features of metabolic syndrome, potentially worsened cancer outcomes in these patients, possible pathogenic mechanisms to explain these relations, and treatment options for those with NAFLD and its progressive counterpart, nonalcoholic steatohepatitis. It is predicted that metabolic syndrome will lead to large increases in the incidence of HCC over the next decades. A better understanding of the relation between these 2 diseases ultimately should lead to improved screening and treatment options for patients with HCC. Cancer 2009;115:5651-61.

Here, we address to what extent mitotic cyclins in the nematode Caenorhabditis elegans provide overlapping functions or distinct biological activities. C. elegans expresses a single A-type cyclin (CYA-1), three typical B-type cyclins (CYB-1, CYB-2.1 and CYB-2.2), and one B3-subfamily member (CYB-3). While we observed clear redundancies between the cyb genes, cyb-1 and cyb-3 also contribute specific essential functions in meiosis and mitosis. CYB-1 and CYB-3 show similar temporal and spatial expression, both cyclins localize prominently to the nucleus, and both associate with CDK-1 and display histone H1 kinase activity in vitro. We demonstrate that inhibition of cyb-1 by RNAi interferes with chromosome congression and causes aneuploidy. In contrast, cyb-3(RNAi) embryos fail to initiate sister chromatid separation. Inhibition of both cyclins simultaneously results in a much earlier and more dramatic arrest. However, only the combination of cyb-1, cyb-3 and cyb2.1/cyb-2.2 RNAi fully resembles cdk-1 inhibition. This combination of redundant and specific phenotypes supports that in vivo phosphorylation of certain Cdk targets can be achieved by multiple Cdk1/cyclin complexes, while phosphorylation of other targets requires a unique Cdk1/cyclin combination.

We present a model of preclinical atherosclerosis based on genetic and clinical data that predicts the presence of coronary artery calcification in healthy Americans of European descent 45 to 84 years of age in the Multi-Ethnic Study of Atherosclerosis (MESA). Methods and Results-We assessed 712 individuals for the presence or absence of coronary artery calcification and assessed their genotypes for 2882 single-nucleotide polymorphisms. With the use of these single-nucleotide polymorphisms and relevant clinical data, a Bayesian network that predicts the presence of coronary calcification was constructed. The model contained 13 single-nucleotide polymorphisms (from genes AGTR1, ALOX15, INSR, PRKAB1, IL1R2, ESR2, KCNK1, FBLN5, PPARA, VEGFA, PON1, TDRD6, PLA2G7, and 1 ancestry informative marker) and 5 clinical variables (sex, age, weight, smoking, and diabetes mellitus) and achieved 85% predictive accuracy, as measured by area under the receiver operating characteristic curve. This is a significant (P<0.001) improvement on models that use just the single-nucleotide polymorphism data or just the clinical variables. Conclusions-We present an investigation of joint genetic and clinical factors associated with atherosclerosis that shows predictive results for both cases, as well as enhanced performance for their combination.

Somatic mutations in the EGFR are found in 10 to 40% of patients with NSCLC. Patients with sensitizing somatic mutations of EGFR treated with gefitinib or erlotinib have an initial clinical response of 60 to 80%, approximately twice as high as the responses associated with the administration of conventional platinum-based chemotherapy. However, the efficacy of EGFR tyrosine kinase inhibitors (TKI) is limited by either primary (de novo) or acquired resistance after therapy and investigations to define the mechanisms of resistance are active areas of ongoing preclinical and clinical studies. Primary resistance is typically caused by other somatic mutations in genes such as KRAS, which also have an impact on the EGFR signaling pathway or by mutations in the EGFR gene that are not associated with sensitivity to EGFR-TKIs. Two established mechanisms of acquired resistance are caused by additional mutations in the EGFR gene acquired during the course of treatment that change the protein-coding sequence or by amplification of another oncogene signaling pathway driven by the MET oncogene. This review focuses on characterized mechanisms of resistance to the EGFR TKIs and efforts to overcome the problem of resistance aimed at improving the therapy of patients with NSCLC.

Surgery is the primary treatment modality, but many patients suffer disease recurrence or metastasis. Fortunately, the management of advanced GIST has been revolutionized by the use of small molecule kinase inhibitors that target the underlying pathogenetic mutant kinases found in the vast majority of cases. Approximately 85% of GISTs have oncogenic mutations in KIT, allowing for constitutive kinase activation that is responsible for cellular proliferation and survival. About 5 to 7% of GISTs have activating mutations of the homologous platelet-derived growth factor receptor alpha (PDGFRA) kinase. The progression-free and overall survival of patients with advanced disease is greatly improved by treatment with the kinase inhibitors imatinib and sunitinib. However, the emergence of drug-resistant tumor clones limits the long-term benefit of these drugs in most patients. Resistance to these kinase inhibitors is associated with distinctive clinical and molecular features, with the development of secondary mutations of the oncogenic kinase being the most common mechanism. We review the molecular basis of GIST response and/or resistance to TKIs, and discuss strategies to prevent and/or overcome drug resistance. These concepts are directly relevant to the development of targeted molecular therapy for other solid tumors.

Experimental Design: Patients with head and neck cancer were registered for molecular analysis of surgical margins. Adequacy of resection was ensured using histologic margin analysis. Further margins were then harvested and DNA extracted. TP53 mutations in tumor were determined using Affymetrix p53 GeneChip. Margins were analyzed by Ligamp in comparison with standard curves for quantification of mutant DNA. Ligation used two oligonucleotides to isolate DNA targeting the mutation. Ligated DNA was amplified using real-time PCR. The quantity of mutation in the margin was determined as percent of mutant species relative to plasmid and relative to tumor. Cutpoints were identified and defined groups were evaluated for local failure-free, cancer-specific, and overall survival. Study margins were examined for presence of tumor by light microscopy. Results: Tissue from 95 patients with common mutations was analyzed. Fifteen experienced local recurrence. Cutpoints of 0.15% for mutant species relative to plasmid and 0.5% for mutant species relative to tumor were chosen as most selective of recurrent cases. LigAmp had slightly better area under the receiver operator characteristic curve (P = 0.09) than light microscopy correctly predicting 9 of 15 recurrent tumors. There were 6 false negative cases and 26 false positive results. No statistically significant distinctions were observed in cancer-specific or overall survival in this limited cohort. Conclusions: Ligamp provides quantifiable, sensitive detection of mutant DNA in histologically normal margins. Detection of mutant species in margins may identify patients at risk of local recurrence. (Clin Cancer Res 2009;15(24):7658-65) C1 [Poeta, M.

TI Noninvasive Prediction of Fracture Risk in Patients with Metastatic Cancer to the Spine SO CLINICAL CANCER RESEARCH LA English DT Article ID BREAST-CANCER; BONE METASTASES; PATHOLOGICAL FRACTURE; COMPUTED-TOMOGRAPHY; THORACIC VERTEBRAE; DEFECTS; MANAGEMENT; STRENGTH; FAILURE; DENSITY AB Purpose: Skeletal metastases affect up to 85% of breast cancer patients by the time of their death. This prospective in vivo study evaluated the diagnostic performance of computed tomography-based structural rigidity analysis (CTRA) to predict vertebral fracture risk in breast cancer patients with skeletal metastasis and in comparison with the current standard of care. Experimental Design: Torso CT scans of 94 women with vertebral metastatic breast cancer were obtained as part of routine screening for lung and liver metastases. The load-bearing capacity (LBC) and axial (EA) and bending (EI) rigidities of vertebrae T8 to L5 were calculated from CT images. The LBC was normalized by patient body mass index (BMI) to account for height and mass variations. Vertebral fracture risk was also calculated using the current radiographic-based criteria based on lesion size and location. The actual occurrence of a new vertebral fracture was assessed radiographically over the ensuing 4 months. Results: Eleven vertebral fractures occurred in 10 patients. The structural parameters EA, El, LBC, and LBC/BMI were all 100% sensitive and 55%, 53%, 44%, and 70% specific to predict fracture risk, respectively. Although radiographic criteria correctly predicted all fracture cases (100% sensitive), only 48 of the 236 spinal segments that did not have a fracture were correctly predicted not to fracture (20% specific). Conclusions: CTRA, using CT scans as part of routine screening for lung and liver metastasis, is shown to be as sensitive as, and significantly more specific than, the current radiographic criteria for predicting vertebral fracture in breast cancer patients with skeletal metastasis.

One-third of the world's population is infected with tuberculosis, and 9 months of isoniazid monotherapy is the treatment of choice for latent tuberculosis infection. However, this approach has been associated with hepatotoxicity and poor compliance. A shorter (4-month) rifampin regimen has been evaluated in recent clinical trials. Methods. We performed a meta-analysis of the published studies to compare compliance, toxicity, and cost-effectiveness between the 2 strategies. Pooled effects were calculated as risk ratios (RRs) by means of random-effects and fixed-effects models. Results. Pooled data from 3586 patients suggested that 4-month rifampin therapy was associated with a significant reduction in the risk of noncompletion (RR for random-effects model, 0.53; 95% confidence interval [CI], 0.44-0.63). Noncompletion rates were lower among patients who received 4-month rifampin therapy (range, 8.6%-28.4%), compared with noncompletion rates among patients who received 9-month isoniazid therapy (range, 24.1%-47.4%). Also, rates of hepatotoxicity (defined as grade 3 or 4 liver failure leading to drug discontinuation) were lower for patients who received 4-month rifampin therapy (range, 0%-0.7%), compared with the corresponding rates for patients who received 9-month isoniazid therapy (range, 1.4%-5.2%), and rifampin was associated with significant reduction in the risk of hepatotoxicity (RR for fixed-effects model, 0.12; 95% CI, 0.05-0.30). Notably, with the data from our meta-analysis, we calculated that the 4-month rifampin strategy is also cost-effective and results in $213 savings per patient treated ($90/patient when doctor fees are not included). Conclusions. The improved compliance, safety, and cost associated with the 4-month rifampin therapy suggest that the efficacy of this approach needs to be evaluated in detail. An extended posttreatment follow-up in future studies will clarify the unresolved issue of tuberculosis reactivation rates.

TI Effectiveness of Pediatric Antiretroviral Therapy in Resource-Limited Settings: A Systematic Review and Meta-analysis SO CLINICAL INFECTIOUS DISEASES LA English DT Article ID HIV-INFECTED CHILDREN; CD4 CELL RESPONSE; HIV-1-INFECTED CHILDREN; OPPORTUNISTIC INFECTIONS; CLINICAL-OUTCOMES; INCOME COUNTRIES; UNITED-KINGDOM; FOLLOW-UP; HAART; MORTALITY AB Background. Responses to antiretroviral therapy (ART) among human immunodeficiency virus (HIV)-infected children in resource-limited settings have recently been reported, but outcomes vary. We sought to derive pooled estimates of the 12-month rate of virologic suppression (HIV RNA, <400 copies/mL) and gain in CD4 cell percentage (Delta CD4%) for children initiating ART in resource-limited settings. Methods. We conducted a systematic review and meta-analysis of published reports of HIV RNA and CD4 outcomes for treatment-naive children aged 0-17 years old by means of the Medline, EMBASE (Excerpta Medica Database), and LILACS (Latin American and Caribbean Health Sciences Literature) electronic databases and the Cochrane Clinical Trials Register. Pooled estimates of the reported proportion with HIV RNA <400 copies/mL and Delta CD4% after 12 months of ART were derived using patient-level estimates and fixed-and random-effects models. To approximate intention-to-treat analyses, in sensitivity analyses children with missing 12-month data were assumed to have HIV RNA>400 copies/mL or Delta CD4% of zero. Results. In patient-level estimates after 12 months of ART, the pooled proportion with virologic suppression was 70% (95% confidence interval [CI], 67%-73%); the pooled Delta CD4% was 13.7% (95% CI, 11.8%-15.7%). Results from the fixed-and random-effects models were similar. In approximated intention-to-treat analyses, the pooled estimates decreased to 53% with virologic suppression (95% CI, 50%-55%) and to a Delta CD4% of 8.5% (95% CI, 5.5%-11.4%). Conclusions. Pooled estimates of reported virologic and immunologic benefits after 12 months of ART among HIV-infected children in resource-limited settings are comparable with those observed among children in developed settings. Consistency in reporting on reasons for missing data will aid in the evaluation of ART outcomes in resource-limited settings.

The disease is caused by mutations in NPHP1-9 genes, which encode the nephrocystins, proteins localized to cell-cell junctions and centrosome/primary cilia. Here, we show that nephrocystin mRNA expression is dramatically increased during cell polarization, and shRNA-mediated knockdown of either NPHP1 or NPHP4 in MDCK cells resulted in delayed tight junction (TJ) formation, abnormal cilia formation and disorganized multi-lumen structures when grown in a three-dimensional collagen matrix. Some of these phenotypes are similar to those reported for cells depleted of the TJ proteins PALS1 or Par3, and interestingly, we demonstrate a physical interaction between these nephrocystins and PALS1 as well as their partners PATJ and Par6 and show their partial co-localization in human renal tubules. Taken together, these results demonstrate that the nephrocystins play an essential role in epithelial cell organization, suggesting a plausible mechanism by which the in vivo histopathologic features of NPH might develop.

TI Active MMP-2 effectively identifies the presence of colorectal cancer SO INTERNATIONAL JOURNAL OF CANCER LA English DT Article DE cancer diagnosis; colorectal carcinomas; active MMP-2 ID GELATINASE-A MMP-2; HUMAN COLON-CANCER; MATRIX METALLOPROTEINASES; IV COLLAGENASES; PROGNOSTIC-SIGNIFICANCE; ENHANCED PRODUCTION; TISSUE INHIBITORS; ACTIVATION; EXPRESSION; METASTASIS AB Fully active MMP-2 is expressed at such low levels in human tissues that studies often fail to confirm its value as a cancer marker despite strong associations with malignancy. Our study utilized careful extraction, accurate activity measurements, standardization to purified controls and a new statistical metric to determine whether active MMP-2 is an effective indicator of colorectal cancer compared to pro-MMP-2 or pro-MMP-9. MMP-2 and MMP-9 activities were analyzed in matched normal and cancer samples from 269 patients by gelatin zymography, computer-assisted image analysis, serial dilutions of strong samples and standardization to controls. An index of effect size was designed for comparative evaluation of active MMP-2, pro-MMP-2 and pro-MMP-9 activities. For each gelatinase, mean activity and protein levels/mg soluble protein in normal mucosa and colorectal cancer were calculated for the first time with respect to commercial standards. Active MMP-2 activity, detected in 99% of colorectal cancers, was higher in 95% of cancers (on average 10-fold) than in normal mucosa. Levels of pro-MMP-2 and pro-MMP-9, but not active MMP-9, activities were also significantly higher in cancers versus normal. However, active MMP-2 activity provided the most effective test for the presence of cancer (p < 0.0.0001) with an effect size statistically significantly larger than for either pro-MMP-2 or pro-MMP-9. Receiver operating characteristic (ROC) curves demonstrated that a cut-off for active MMP-2 of >44 SDU activity/mg soluble protein (>180 pg/mg), which is three times mean normal levels, would permit detection of colorectal cancer with an estimated sensitivity of 84% and estimated specificity of 93%.

The potential role of IGF1R has been postulated in a small subset of GISTs, but until now the implications of its aberrations have not been defined. The aim of the study was to examine the IGF1R status in patients with gastric GIST in regard to KIT and PDGFRA genotype. Fresh resection specimens were collected from 8 primary tumours [2 wild-type (WT) and 6 mutant cases]. IGF1R was studied as gene expression profiling with Affymetrix GeneChip HG-U133Plus 2.0 arrays and as genomic copy number with SNP array analysis Affymetrix Genome Wide Human SNP 6.0 arrays, and at protein level with western blotting (WB) and immunohistochemistry (IHC). The unsupervised analysis of gene expression profiling of our patients merged with a data set from gastric GISTs identified 2 patients out of 8 with different expression of IGF1R. The data were confirmed by WB and IHC. In particular, IGF1R was upregulated in 2 young patients (<30-years old), who had both WT disease and metastases at diagnosis. The SNP array analysis showed that none of the tumours had IGF1R amplification. GISTs are characterized by abnormalities of the KIT and PDGFRA receptors that affect prognosis and response to tyrosine kinase inhibitors. Both young adult with WT GIST had the overexpression of IGF1R at mRNA and protein level. These results further confirm the hypothesis that IGF1R may be a potential therapeutic target in GISTs lacking KIT and PDGFRA mutations.

TI On the Use of Adjusted Cross-Sectional Estimators of HIV Incidence SO JAIDS-JOURNAL OF ACQUIRED IMMUNE DEFICIENCY SYNDROMES LA English DT Article DE BED; detuned ELISA; sensitive/less sensitive tests ID CAPTURE ENZYME-IMMUNOASSAY; INCIDENCE RATES; INFECTION; ANTIBODIES; STRATEGY; AFRICA; TESTS AB Objective: To elucidate when and how cross-sectional estimators of HIV incidence rates based on a sensitive and less sensitive diagnostic test should be adjusted. Methods: Evaluate the statistical properties of unadjusted and adjusted cross-sectional estimators of HIV incidence, including the adjusted estimators considered by McDougal et al, for the 2 settings where (a) all infected subjects eventually become reactive to the less sensitive test, and (b) a subset of infected subjects indefinitely remain nonreactive to the less sensitive test. Derive the maximum likelihood estimator of incidence for the latter setting and use analytical results and simulation studies to compare the performance of the various estimators. Results: When every infected subject would eventually become reactive to the less sensitive test, the McDougal adjusted estimator is uniformly less precise than the unadjusted estimator and more susceptible to bias. When a subset of the infected population would indefinitely remain nonreactive to the less sensitive test, the McDougal adjusted estimator is less precise than the maximum likelihood estimator, which coincides with an estimator developed by McWalter and Welte using a mathematical modeling approach. When the assumed model is incorrect, the unadjusted estimator overestimates incidence, whereas the maximum likelihood estimator can be biased in either direction. Conclusions: The standard unadjusted cross-sectional estimator of HIV incidence should be used when all infected individuals would eventually become reactive to the less sensitive test. When a subset of individuals would indefinitely remain nonreactive to the less sensitive test, the maximum likelihood estimator for this setting should be used. Characterizing the proportion of individuals who would indefinitely remain nonreactive is crucial for accurate estimation of HIV incidence.

TI Cryo-Electron Tomography Elucidates the Molecular Architecture of Treponema pallidum, the Syphilis Spirochete SO JOURNAL OF BACTERIOLOGY LA English DT Review ID OUTER-MEMBRANE PROTEINS; FRACTURE ELECTRON-MICROSCOPY; BORRELIA-BURGDORFERI LIPOPROTEINS; FILAMENT-DEFICIENT MUTANT; LIMITED SURFACE EXPOSURE; LYME-DISEASE SPIROCHETE; GRAM-NEGATIVE BACTERIA; PERIPLASMIC FLAGELLA; ESCHERICHIA-COLI; BINDING PROTEINS AB Cryo-electron tomography (CET) was used to examine the native cellular organization of Treponema pallidum, the syphilis spirochete. T. pallidum cells appeared to form flat waves, did not contain an outer coat and, except for bulges over the basal bodies and widening in the vicinity of flagellar filaments, displayed a uniform periplasmic space. Although the outer membrane (OM) generally was smooth in contour, OM extrusions and blebs frequently were observed, highlighting the structure's fluidity and lack of attachment to underlying periplasmic constituents. Cytoplasmic filaments converged from their attachment points opposite the basal bodies to form arrays that ran roughly parallel to the flagellar filaments along the inner surface of the cytoplasmic membrane (CM). Motile treponemes stably attached to rabbit epithelial cells predominantly via their tips. CET revealed that T. pallidum cell ends have a complex morphology and assume at least four distinct morphotypes. Images of dividing treponemes and organisms shedding cell envelope-derived blebs provided evidence for the spirochete's complex membrane biology. In the regions without flagellar filaments, peptidoglycan (PG) was visualized as a thin layer that divided the periplasmic space into zones of higher and lower electron densities adjacent to the CM and OM, respectively. Flagellar filaments were observed overlying the PG layer, while image modeling placed the PG-basal body contact site in the vicinity of the stator-P-collar junction. Bioinformatics and homology modeling indicated that the MotB proteins of T. pallidum, Treponema denticola, and Borrelia burgdorferi have membrane topologies and PG binding sites highly similar to those of their well-characterized Escherichia coli and Helicobacter pylori orthologs. Collectively, our results help to clarify fundamental differences in cell envelope ultrastructure between spirochetes and gram-negative bacteria. They also confirm that PG stabilizes the flagellar motor and enable us to propose that in most spirochetes motility results from rotation of the flagellar filaments against the PG.

However, the rapid in vivo degradation rate of PGS limits its use as a scaffold material. To determine the impact of crosslink density on degradation rate, a family of PGS materials was synthesized by incrementally increasing the curing time from 42 to 144 h, at 120 degrees C and 10 mTorr vacuum. As expected, PGS became a stiffer, tougher, and stronger elastomer with increasing curing time. PGS disks were Subcutaneously implanted into rats and periodically harvested only mild tissue responses were observed and the biocompatibility remained excellent. Regardless of crosslink density, surface erosion degradation was observed. The sample dimensions linearly decreased with implantation time, and the mass loss rates were constant after 1-week implantation. As surface erosion degradation frequently correlates with enzymatic digestion, parallel in vitro digestion studies were conducted in lipase solutions which hydrolyze ester bonds. Enzymatic digestion played a significant role in degrading PGS, and the mass-loss rates were not a function of curing time. Alternative chemistry approaches will be required to decrease the enzymatic hydrolysis rate of the ester bonds in PGS polymers. (C) 2008 Wiley Periodicals, Inc.

TI Idiopathic Hypersomnia: Clinical Features and Response to Treatment SO JOURNAL OF CLINICAL SLEEP MEDICINE LA English DT Article DE Idiopathic hypersomnia; treatment; modafinil; methylphenidate; stimulants ID CENTRAL ORIGIN; NARCOLEPSY AB Objective: A recent American Academy of Sleep Medicine publication identified a need for research regarding idiopathic hypersomnia. We describe various clinical and polysomnographic features of patients with idiopathic hypersomnia, with an emphasis on response to pharmacotherapy. Methods: A retrospective review of our database initially identified 997 patients, utilizing "idiopathic hypersomnia," "hypersomnia NOS," and "primary hypersomnia" as keywords. The charts of eligible patients were examined in detail, and data were abstracted and analyzed. Response to treatment was graded utilizing an internally developed scale. Results: Eighty-five patients were ultimately identified (65% female). Median (interquartile range) ages of onset and diagnosis were 19.6 (15.5) and 33.7 (15.5), respectively. During a median follow-up duration of 2.4 (4.7) years, 65% of patients demonstrated a "complete response" to phamnacotherapy as assessed by the authors' grading schema. Methylphenidate was most commonly used as a first-line agent prior to December 1998, but subsequently, modafinil became the most common first drug. At the last recorded follow-up visit, 92% of patients were on monotherapy, with greater representation of methylphenidate versus modafinil (51% vs. 32%). Among these patients, methylphenidate produced a higher percentage of "complete" or "partial" responses than modafinil, although statistical significance was not reached (38/40 [95%] vs 22/25 [88%], respectively, p = 0.291). Conclusions: The majority of patients with idiopathic hypersomnia respond well to treatment. Methylphenidate is chosen more often than modafinil as final monotherapy in the treatment of idiopathic hypersomnia, despite the fact that it is less commonly used initially. Further prospective comparisons of medications should be explored. C1 [Auger, R. Robert; Slocumb, Nancy L.; Morgenthaler, Timothy I.] Mayo Clin, Ctr Sleep Med, Rochester, MN USA. [Auger, R.

TI Activation, Immune Polarization, and Graft-versus-Leukemia Activity of Donor T Cells Are Regulated by Specific Subsets of Donor Bone Marrow Antigen-Presenting Cells in Allogeneic Hemopoietic Stem Cell Transplantation SO JOURNAL OF IMMUNOLOGY LA English DT Article ID PLASMACYTOID DENDRITIC CELLS; COLONY-STIMULATING FACTOR; HOST-DISEASE; IN-VIVO; ADAPTIVE IMMUNITY; LANGERHANS CELLS; LYMPHOID ORGANS; MOUSE; RESPONSES; PRECURSORS AB We investigated the roles of specific subsets of donor APCs purified from bone marrow in donor T cell activation and graft-vs-leukemia (GvL) activity in murine models of hemopoietic stem cell transplantation. Lineage(-)CD11c(+) APC precursors were separated from donor bone marrow based on expression of CD11b. Transplanting lineage(-)CD11c(+)CD11b(-) APC (CD11b(-) APC) in combination with c-kit(+)Sca-1(+)lineage(-) hemopoietic stem cells (HSC) and congenic donor T cells led to increased donor CD4(+) and CD8(+) T cell proliferation and higher donor T cell chimerism than with transplanting grafts containing HSC, T cells, and lineage(-)CD11c(+)CD11b(+) APCs (CD11b(+) APC), or grafts containing only HSC and T cells. Transplanting CD11b(-) APCs induced Th1/type 1 cytotoxic T lymphocyte donor T cell immune polarization and enhanced GvL activity of donor T cells without increased graft-vs-host disease in both MHC- and minor histocompatibility Ag-mismatched murine hemopoietic stem cell transplantation models, whereas CD11b(+) APCs led to Th2/type 2 cytotoxic T lymphocyte donor T cell immune polarization. Donor CD11b- APCs were plasmacytoid dendritic cell progenitors (>90% CD317; PDCA-1(+)) and up-regulated CD80, CD86, and IL-12 during alloantigen presentation, whereas CD11b(+) APCs expressed Gr-1 and up-regulated expression of programmed death ligands-1 and 2 after activation. These results are the first to show that manipulation of the content of donor APCs in allogeneic HSC grafts can regulate donor T cell immunity and enhance GvL without increasing graft-vs-host disease activity.

TI Dual Control of Antitumor CD8 T Cells through the Programmed Death-1/Programmed Death-Ligand 1 Pathway and Immunosuppressive CD4 T Cells: Regulation and Counterregulation SO JOURNAL OF IMMUNOLOGY LA English DT Article ID CHRONIC VIRAL-INFECTION; TUMOR-SPECIFIC CD8; IN-VIVO; DENDRITIC CELLS; INDUCIBLE COSTIMULATOR; SOLID TUMORS; EFFECTOR; EXPRESSION; RESPONSES; PD-1 AB Tumors have evolved multiple mechanisms to evade immune destruction. One of these is expression of T cell inhibitory ligands such as programmed death-ligand 1 (PD-L1; B7-H1). In this study, we show that PD-L1 is highly expressed on mesothelioma tumor cells and within the tumor stroma. However, PD-L1 blockade only marginally affected tumor growth and was associated with the emergence of activated programmed death-1(+) ICOS(+) CD4 T cells in tumor-draining lymph nodes, whereas few activated CD8 T cells were present. Full activation of antitumor CD8 T cells, characterized as programmed death-1(+) ICOS(+) Ki-67(+) and displaying CTL activity, was only observed when CD4 T cells were depleted, suggesting that a population of suppressive CD4 T cells exists. ICOS(+) foxp3(+) regulatory T cells were found to be regulated through PD-L1, identifying one potentially suppressive CD4 T cell population. Thus, PD-L1 blockade activates antitumor CD8 T cell most potently in the absence of CD4 T cells. These findings have implications for the development of PD-L1-based therapies.

To explore a potential role for IEX-1 in control of the susceptibility to Leishmania major infection, the inflammatory response during cutaneous leishmaniasis was evaluated in 129Sv/C57BL/6-resistant mice in the presence or absence of IEX-1. Null mutation of IEX-1 enhanced the susceptibility of the mice to L. major infection, and aggravated inflammatory responses in comparison with wild-type control mice. The excessive inflammation was not ascribed to a Th2-biased immune response or a defect in Th1 polarization, but rather to an elevated level of IL-17 production by both gamma delta T and CD4(+) cells, concomitant with an increase of the neutrophil recruitment early in the infection. The lack of IEX-1 also suppressed TNF-alpha production in both macrophages and T cells, resulting in a high intralesional load, of parasites-and delayed healing of the lesion, both of which were reversed by TNF-alpha treatment. These findings indicate the crucial role of IL-17 and TNF-alpha in determining the outcome of L. major infection beyond a balance between Th1- and Th2-mediated immune responses.

B. burgdorferi isolates from the United States induced macrophages to secrete significantly higher levels of interleukin (IL)-8, CCL3, CCL4, IL-6, IL-10, and tumor necrosis factor than B. garinii or B. afzelii isolates. Consistent with this response in cultured macrophages, chemokine and cytokine levels in serum samples of patients from whom the isolates were obtained were significantly greater in B. burgdorferi-infected patients than in B. afzelii-or B. garinii-infected patients. These results demonstrate in vitro and in vivo that B. burgdorferi has greater inflammatory potential than B. afzelii and B. garinii, which may account in part for variations in the clinical manifestations of Lyme borreliosis.

Background In the PROVE IT-TIMI 22 (Pravastatin or Atorvastatin Evaluation and Infection Therapy-Thrombolysis In Myocardial Infarction 22) trial, more intensive lipid lowering with high-dose atorvastatin reduced the first occurrence of the primary end point (death, myocardial infarction, unstable angina requiring rehospitalization, stroke, or revascularization >= 30 days) compared with moderate lipid lowering with pravastatin. Methods Poisson regression analysis was performed to compare the number of occurrences of the primary end point between high-dose atorvastatin and pravastatin in the PROVE IT-TIMI 22 trial. Results As previously reported, first primary end point events were reduced by 16% with atorvastatin 80 mg versus pravastatin 40 mg (n = 464 vs. n = 537, respectively; p = 0.005). Additional events were also reduced by 19% with atorvastatin 80 mg (n = 275 vs. n = 340, respectively; p = 0.009). Overall, there were 138 fewer primary efficacy events with atorvastatin 80 mg versus pravastatin 40 mg (n = 739 vs. n = 877, respectively; rate ratio: 0.85, 95% confidence interval: 0.77 to 0.94, p = 0.001). Conclusions Although analytic techniques commonly used in clinical outcomes trials censor patients who experience a component of the primary composite end point, total cardiovascular events are important to patients, clinicians, and health care payers. Maintaining low levels of low-density lipoprotein cholesterol is central to preventing additional atherosclerotic development and subsequent cardiovascular events. Atorvastatin 80 mg, a more intensive low-density lipoprotein cholesterol lowering agent, reduced both first and subsequent primary end point events compared with pravastatin 40 mg after ACS.

SO JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY LA English DT Article DE menopause; risk factors; lipids; inflammation; race ID CORONARY-HEART-DISEASE; HEALTHY WOMEN; NATION SWAN; AGE; POPULATION; STANDARDIZATION; PREMENOPAUSAL; CHOLESTEROL; HORMONE; WEIGHT AB Objectives This prospective study examined whether changes in traditional and novel coronary heart disease (CHD) risk factors are greater within a year of the final menstrual period (FMP), relative to changes that occur before or after that interval, in a multiethnic cohort. Background Understanding the influence of menopause on CHD risk remains elusive and has been evaluated primarily in Caucasian samples. Methods SWAN (Study of Women's Health Across the Nation) is a prospective study of the menopausal transition in 3,302 minority (African American, Hispanic, Japanese, or Chinese) and Caucasian women. After 10 annual examinations, 1,054 women had achieved an FMP not due to surgery and without hormone therapy use before FMP. Measured CHD risk factors included lipids and lipoproteins, glucose, insulin, blood pressure, fibrinogen, and C-reactive protein. We assessed which of 2 models provided a better fit with the observed risk factor changes over time in relation to the FMP: a linear model, consistent with chronological aging, or a piecewise linear model, consistent with ovarian aging. Results Only total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B demonstrated substantial increases within the 1-year interval before and after the FMP, consistent with menopause-induced changes. This pattern was similar across ethnic groups. The other risk factors were consistent with a linear model, indicative of chronological aging. Conclusions Women experience a unique increase in lipids at the time of the FMP. Monitoring lipids in perimenopausal women should enhance primary prevention of CHD.

Background CCTA has recently been found to be effective in the evaluation of patients with suspected CAD, but investigators have raised concerns related to radiation exposure, incidental findings, and nondiagnostic exams. Methods With published data, we developed a computer simulation model to project clinical outcomes, health care costs, and cost-effectiveness of CCTA, compared with conventional testing modalities, in the diagnosis of CAD. Our target population included 55-year-old patients who present to their primary care physicians with stable chest pain. Results All diagnostic strategies yielded similar health outcomes, but performing CCTA-with or without stress testing or performing stress single-photon emission computed tomography-marginally minimized adverse events and maximized longevity and quality-adjusted life-years (QALYs). Health outcomes associated with these strategies were comparable, with CCTA in men and women yielding the greatest QALYs but only by modest margins. Overall differences were small, and performing the most effective test-compared with the least effective-decreased adverse event rates by 3% in men and women. Comparable increases in longevity and QALYs were 2 months and 0.1 QALYs in men and 1 month and 0.03 QALYs in women. CCTA raised overall costs, partly through the follow-up of incidental findings, and when performed with stress testing, its incremental cost-effectiveness ratio ranged from $26,200/QALY in men to $35,000/QALY in women. Health outcomes were marginally less favorable in women when radiation risks were considered. Conclusions CCTA is comparable to other diagnostic studies and might hold good clinical value, but large randomized controlled trials are needed to guide policy.

Japanese patients (n = 5193) were enrolled into the REACH registry between August and December 2004. One-year event rate in patients with cerebrovascular disease (CVD) was compared with that of patients with symptomatic atherothrombosis at other locations. After one year (n = 5021), patients with CVD (n = 1962) experienced a higher rate of non-fatal strokes than patients with coronary artery disease (CAD), peripheral artery disease (PAD) or MRFs alone (2.77% vs. 1.28%, 2.07% and 1.56%, respectively), but a lower rate of non-fatal myocardial infarction (0.45% vs. 131%, 0.77% and 0.66%, respectively). Patients with CVD plus disease in >= 1 other vascular bed had higher rates of cardiovascular events than patients with CVD alone. Overall, event rates including non-fatal stroke, non-fatal myocardial infarction and cardiovascular death were higher for patients with CVD and PAD than for patients with CVD and CAD. Asymptormatic carotid stenosis >= 70% and ankle-brachial index < 0.9 were significant predisposing factors for stroke. Patients with CVD and co-existing atherothrombotic diseases had a high risk of recurrent events, including events arising in other vascular beds than originally diagnosed. (C) 2009 Elsevier B.V.

We hypothesized that differences in electrode position and surgical trajectory may lead to a differential neuropsychological outcome. Methods: We conducted a standardized evaluation of the location of the DBS electrode tip and the active electrodes, the surgical trajectory through which they were placed, and their relation to neuropsychological change scores (mental status, verbal memory, verbal fluency, and psychological measures) in 17 bilateral STN DBS patients using 6 month post-surgical magnetic resonance imaging data. Results: Declines in mental status scores were related to electrodes that were more posterior-laterally placed within the frontal quadrant in either hemisphere or those located superiorally in the left hemisphere. Electrodes that were closer to the approximated STN and more superiorally located in the left hemisphere were associated with verbal learning declines at 6 months following surgery. In the right hemisphere, the electrodes that were located more in the lateral direction were related to verbal short-term memory declines; while for verbal long-term memory declines were found for electrodes located more posterior-laterally in the left hemisphere. Declines in verbal fluency scores were more variable with associations found between change scores and electrodes in the lateral and superior directions in the left hemisphere and those electrodes closer to the approximated STN and more superiorally and posteriorally located in the right hemisphere. In contrast, semantic fluency declines were only related to right hemisphere electrodes located more superiorally. Declines in mood were related to those electrodes located further away from the approximated STN, particularly those located more inferiorally and laterally in the left hemisphere. Anxiety change scores were not associated with the location of the electrodes. Conclusions: The results provide preliminary evidence that 6 months following bilateral STN DBS cognitive and emotional changes may be related to the surgical trajectory and electrode placement.

TI XPF-ERCC1 Participates in the Fanconi Anemia Pathway of Cross-Link Repair SO MOLECULAR AND CELLULAR BIOLOGY LA English DT Article ID NUCLEOTIDE EXCISION-REPAIR; DNA-DAMAGE RESPONSE; SACCHAROMYCES-CEREVISIAE; MAMMALIAN-CELLS; MONOUBIQUITINATED FANCD2; ENDONUCLEASE ERCC1-XPF; ESCHERICHIA-COLI; NITROGEN MUSTARD; UBIQUITIN LIGASE; FOCUS FORMATION AB Interstrand cross-links (ICLs) prevent DNA strand separation and, therefore, transcription and replication, making them extremely cytotoxic. The precise mechanism by which ICLs are removed from mammalian genomes largely remains elusive. Genetic evidence implicates ATR, the Fanconi anemia proteins, proteins required for homologous recombination, translesion synthesis, and at least two endonucleases, MUS81-EME1 and XPF-ERCC1. ICLs cause replication-dependent DNA double-strand breaks (DSBs), and MUS81-EME1 facilitates DSB formation. The subsequent repair of these DSBs occurs via homologous recombination after the ICL is unhooked by XPF-ERCC1. Here, we examined the effect of the loss of either nuclease on FANCD2 monoubiquitination to determine if the nucleolytic processing of ICLs is required for the activation of the Fanconi anemia pathway. FANCD2 was monoubiquitinated in Mus81(-/-), Ercc1(-/-), and XPF-deficient human, mouse, and hamster cells exposed to cross-linking agents. However, the monoubiquitinated form of FANCD2 persisted longer in XPF-ERCC1-deficient cells than in wild-type cells. Moreover, the levels of chromatin-bound FANCD2 were dramatically reduced and the number of ICL-induced FANCD2 foci significantly lower in XPF-ERCC1-deficient cells. These data demonstrate that the unhooking of an ICL by XPF-ERCC1 is necessary for the stable localization of FANCD2 to the chromatin and subsequent homologous recombination-mediated DSB repair.

We assessed sex differences and the influence of gonadal hormone fluctuations and exogenous manipulations of estrogen and progesterone on acquisition, extinction learning and extinction recall in a 3 day auditory fear conditioning and extinction protocol. Experiments were conducted on males and naturally cycling female rats. Regarding female rats, significant differences in fear extinction were observed between subgroups of females, depending on their phase of the estrous cycle. Extinction that took place during the proestrus (high estrogen/progesterone) phase was more fully consolidated, as evidenced by low freezing during a recall test. This suggests that estrogen and/or progesterone facilitate extinction. In support of this, injection of both estrogen and progesterone prior to extinction learning in female rats during the metestrus phase of the cycle (low estrogen/progesterone) facilitated extinction consolidation, and blockade of estrogen and progesterone receptors during the proestrus phase impaired extinction consolidation. When comparing male to female rats without consideration of the estrous cycle phase, no significant sex differences were observed. When accounting for cycle phase in females, sex differences were observed only during extinction recall. Female rats that underwent extinction during the metestrus phase showed significantly higher freezing during the recall test relative to males. Collectively, these data suggest that gonadal hormones influence extinction behavior possibly by influencing the function of brain regions involved in the consolidation of fear extinction. Moreover, the elevated fear observed in female relative to male rats during extinction recall suggests that gonadal hormones may in part play a role in the higher prevalence of anxiety disorders in women.

Thus techniques that can sensitively detect metastatic colonization and assess treatment response in real-time are urgently needed. To this end, we engineered tumor cells to express a naturally secreted Gaussia luciferase (Gluc), and investigated its use as a circulating biomarker for monitoring viable metastatic or primary tumor growth and their treatment responses. Methodology/Principal Findings: We first developed orthotopic primary and metastatic breast tumors with derivative of MDA-MB-231 cells expressing Gluc. We then correlated tumor burden with Gluc activity in the blood and urine along with bioluminescent imaging (BLI). Second, we utilized blood Gluc assay to monitor treatment response to lapatinib in an experimental model of systemic metastasis. We observed good correlation between the primary tumor volume and Gluc concentration in blood (R(2) = 0.84) and urine (R(2) = 0.55) in the breast tumor model. The correlation deviated as a primary tumor grew due to a reduction in viable tumor fraction. This was also supported by our mathematical models for tumor growth to compare the total and viable tumor burden in our model. In the experimental metastasis model, we found numerous brain metastases as well as systemic metastases including bone and lungs. Importantly, blood Gluc assay revealed early growth of metastatic tumors before BLI could visualize their presence. Using secreted Gluc, we localized systemic metastases by BLI and quantitatively monitored the total viable metastatic tumor burden by blood Gluc assay during the course of treatment with lapatinib, a dual tyrosine kinase inhibitor of EGFR and HER2. Conclusion/Significance: We demonstrated secreted Gluc assay accurately reflects the amount of viable cancer cells in primary and metastatic tumors. Blood Gluc activity not only tracks metastatic tumor progression but also serves as a longitudinal biomarker for tumor response to treatments.

Exercise remains the single best intervention for PAD, in part thought to be mediated by increases in capillary density. How exercise triggers angiogenesis is not known. PPAR gamma coactivator (PGC)-1 alpha is a potent transcriptional coactivator that regulates oxidative metabolism in a variety of tissues. We show here that PGC-1 alpha mediates exercise-induced angiogenesis. Voluntary exercise induced robust angiogenesis in mouse skeletal muscle. Mice lacking PGC-1 alpha in skeletal muscle failed to increase capillary density in response to exercise. Exercise strongly induced expression of PGC-1 alpha from an alternate promoter. The induction of PGC-1 alpha depended on beta-adrenergic signaling. beta-adrenergic stimulation also induced a broad program of angiogenic factors, including vascular endothelial growth factor (VEGF). This induction required PGC-1 alpha. The orphan nuclear receptor ERR alpha mediated the induction of VEGF by PGC-1 alpha, and mice lacking ERR alpha also failed to increase vascular density after exercise. These data demonstrate that beta-adrenergic stimulation of a PGC-1 alpha/ERR alpha/VEGF axis mediates exercise-induced angiogenesis in skeletal muscle.

TI EGFR Signaling Through an Akt-SREBP-1-Dependent, Rapamycin-Resistant Pathway Sensitizes Glioblastomas to Antilipogenic Therapy SO SCIENCE SIGNALING LA English DT Article ID TYROSINE KINASE INHIBITORS; GROWTH-FACTOR RECEPTOR; CANCER-CELLS; ACQUIRED-RESISTANCE; PROTEIN-KINASE; METABOLISM; RECURRENT; TUMOR; PROLIFERATION; CHOLESTEROL AB Glioblastoma, the most common malignant brain tumor, is among the most lethal and difficult cancers to treat. Although epidermal growth factor receptor ( EGFR) mutations are frequent in glioblastoma, their clinical relevance is poorly understood. Studies of tumors from patients treated with the EGFR inhibitor lapatinib revealed that EGFR induces the cleavage and nuclear translocation of the master transcriptional regulator of fatty acid synthesis, sterol regulatory element-binding protein 1 (SREBP-1). This response was mediated by Akt; however, clinical data from rapamycin-treated patients showed that SREBP-1 activation was independent of the mammalian target of rapamycin complex 1, possibly explaining rapamycin's poor efficacy in the treatment of such tumors. Glioblastomas without constitutively active EGFR signaling were resistant to inhibition of fatty acid synthesis, whereas introduction of a constitutively active mutant form of EGFR, EGFRvIII, sensitized tumor xenografts in mice to cell death, which was augmented by the hydroxymethylglutaryl coenzyme A reductase inhibitor atorvastatin. These results identify a previously undescribed EGFR-mediated prosurvival metabolic pathway and suggest new therapeutic approaches to treating EGFR-activated glioblastomas.

Cadaveric biomechanical study. Objective. To quantify spinal motion created by transfer methods from supine to prone position in a cadaveric C1-C2 global instability model. Summary of Background Data. Patients who have sustained a spinal cord injury remain at high risk for further secondary injury until their spine is adequately stabilized. To date, no study has evaluated the effect of patient transfer methods from supine to prone position in the operating room, on atlantoaxial cervical spine motion. Methods. A global instability was surgically created at the C1-C2 level in 4 fresh cadavers. Two transfer protocols were tested on each cadaver. The log-roll technique entailed performing a standard 180 log-roll rotation of the supine patient from a stretcher to the prone position onto the operating room Jackson table (OSI, Union City, CA). The "Jackson technique" involved sliding the supine patient to the Jackson table, securing them to the table, and then rotating them into a prone position. An electromagnetic tracking device registered motion between the C1 and C2 vertebral segments. Three different head holding devices (Mayfield, Prone view, and blue foam pillow) were also compared for their ability to restrict C1-C2 motion. Six motion parameters were tracked. Repeated measures statistical analysis was performed to evaluate angular and translational motion. Results. For 6 of 6 measures of angulation and translation, manual log-roll prone positioning generated significantly more C1-C2 motion than the Jackson table turning technique. Out of 6 motion parameters, 5 were statistically significant (P < 0.001-0.005). There was minimal difference in C1-C2 motion generated when comparing all 3 head holding devices. Conclusion. The data demonstrate that manual log-roll technique generated significantly more C1-C2 motion compared to the Jackson table technique. Choice of headrest has a minimal effect on the amount of motion generated during patient transfer, except that the Mayfield device demonstrates a slight trend toward increased C1-C2 motion.

We formulated the hypothesis that a high-fat diet may influence the UV-induced inflammatory responses in the skin. C57BL/6 mice were fed a high-fat diet or control diet and exposed to UVB radiation (120 mJ/cm(2)) three times/week for 10 weeks. The mice were then sacrificed and skin and plasma samples collected for analysis of biomarkers of inflammatory responses using immunohistochemistry, western blotting, ELISA and real-time PCR. We found that the levels of inflammatory biomarkers were increased in the UVB-exposed skin of the mice fed the high-fat diet than the UVB-exposed skin of the mice fed the control diet. The levels of inflammatory biomarkers of early responses to UVB exposure (e.g., myeloperoxidase, cyclooxygenase-2, prostaglandin-E(2)), proinflammatory cytokines (i.e., tumor necrosis factor-alpha, interleukin-1 beta, interleukin-6), and proliferating cell nuclear antigen and cell survival signals (phosphatidylinositol-3-kinase and p-Akt-Ser(473)) were higher in high-fat-diet-fed mouse skin than control-diet-fed mouse skin. The plasma levels of insulin growth factor-1 were greater in the UVB-irradiated mice fed the high-fat diet than the UVB-irradiated mice fed the control diet, whereas the levels of plasma adiponectin were significantly lower. This pronounced exacerbation of the UVB-induced inflammatory responses in the skin of mice fed a high-fat diet suggests that high-fat diet may increase susceptibility to inflammation-associated skin diseases, including the risk of skin cancer.

Methods: Derived from the Health Professionals Follow-up Study, we studied colorectal cancer-specific and overall mortality in a cohort of 668 men with a history of stage I to stage III colorectal cancer according to pre-defined physical activity categories after diagnosis. To minimize bias by occult recurrences, we excluded men who died within 6 months of their post diagnosis physical activity assessment. Results: In a cohort of men with colorectal cancer and no apparent metastases at diagnosis, 50.4% exercised at least 18 metabolic equivalent task (MET) hours per week. Increased physical activity was significantly associated with improved colorectal cancer-specific mortality (P = .002 for trend) and overall mortality (P < .001 for trend). Men who engaged in more than 27 MET hours per week of physical activity had an adjusted hazard ratio for colorectal cancer-specific mortality of 0.47 (95% confidence interval, 0.24-0.92) compared with men who engaged in 3 or less MET hours per week of physical activity. The apparent benefit of physical activity was seen regardless of age, disease stage, body mass index, diagnosis year, tumor location, and pre-diagnosis physical activity. Conclusion: In a large cohort of men with a history of nonmetastatic colorectal cancer, more physical activity was associated with a lower risk of colorectal cancer-specific and overall mortality.

We tested the hypothesis that higher levels of PA are associated with a lower risk of kidney function decline using longitudinal data from a large cohort of older adults. Methods: We studied 4011 ambulatory participants aged 65 or older from the Cardiovascular Health Study (CHS) who completed at least 2 measurements of kidney function over 7 years. We calculated a PA score (range, 2-8) by summing kilocalories expended per week (ordinal score of 1-5 from quintiles of kilocalories per week) and walking pace (ordinal score for categories of <2, 2-3, and >3 mph). Rapid decline in kidney function decline (RDKF) was defined by loss of more than 3.0 mL/min/1.73 m(3) per year in glomerular filtration rate, which we estimated by using longitudinal measurements of cystatin C levels. Results: A total of 958 participants had RDKF (23.9%; 4.1 events per 100 person-years). The estimated risk of RDKF was 16% in the highest PA group (score of 8) and 30% in the lowest PA group (score of 2). After multivariate adjustment, we found that the 2 highest PA groups (scores of 7-8) were associated with a 28% lower risk of RDKF (95% confidence interval, 21%-41% lower risk) than the 2 lowest PA groups (score of 2-3). Greater kilocalories of leisure-time PA and walking pace were also each associated with a lower incidence of RDKF. Conclusion: Higher levels of PA are associated with a lower risk of RDKF among older adults. C1 [Robinson-Cohen, Cassianne] Univ Washington, Dept Epidemiol, Seattle, WA 98195 USA.

Methods: Prospective cohort study of 136 293 community-dwelling postmenopausal women in the Women's Health Initiative (WHI). Women taking no antidepressants at study entry and who had at least 1 follow-up visit were included. Cardiovascular morbidity and all-cause mortality for women with new antidepressant use at follow-up (n = 5496) were compared with those characteristics for women taking no antidepressants at follow-up (mean follow-up, 5.9 years). Results: Antidepressant use was not associated with coronary heart disease (CHD). Selective serotonin reuptake inhibitor (SSRI) use was associated with increased stroke risk (hazard ratio [HR], 1.45, [95% CI, 1.08-1.97]) and all-cause mortality (HR,1.32 [95% Cl, 1.10-1.59]). Annualized rates per 1000 person-years of stroke with no antidepressant use and SSRI use were 2.99 and 4.16, respectively, and death rates were 7.79 and 12.77. Tricyclic antidepressant (TCA) use was associated with increased risk of all-cause mortality (HR, 1.67 [95% CI, 1.33-2.09]; annualized rate, 14.14 deaths per 1000 person-years). There were no significant differences between SSRI and TCA use in risk of any outcomes. In analyses by stroke type, SSRI use was associated with incident hemorrhagic stroke (HR, 2.12 [95% Cl, 1.10-4.07]) and fatal stroke (HR, 2.10 [95% CI, 1.15-3.81]). Conclusions: In postmenopausal women, there were no significant differences between SSRI and TCA use in risk of CHD, stroke, or mortality. Antidepressants were not associated with risk of CHD. Tricyclic antidepressants and SSRIs may be associated with increased risk of mortality, and SSRIs with increased risk of hemorrhagic and fatal stroke, although absolute event risks are low. These findings must be weighed against quality of life and established risks of cardiovascular disease and mortality associated with untreated depression.

TI Spouse-Rated vs Self-rated Health as Predictors of Mortality SO ARCHIVES OF INTERNAL MEDICINE LA English DT Article ID QUALITY-OF-LIFE; FUNCTIONAL STATUS; PROXY AGREEMENT; OLDER; PERSPECTIVE; EXPECTANCY; PATIENT; IMPACT AB Background: The Health and Retirement Study is a national sample of Americans older than 50 years and their spouses. The present study evaluated cross-sectional and longitudinal data from January 2000 through December 2006. The objective of the study was to evaluate the roles of spouse-rated vs self-rated health as predictors of all-cause mortality among adults older than 50 years. Methods: A total of 673 dyads of married couples were randomly selected to participate in a Health and Retirement Study module examining spouse-rated health. For each couple, one member was asked to rate his or her overall health status, and his or her spouse was asked to report the partner's overall health status. Mortality data were available through 2006. Results: our findings demonstrate that spouse-rated health (area under the curve, 0.75) is as strong a predictor of mortality as self-rated health (area under the curve, 0.73) (chi(2)(1) = 0.36, P = .54). Combining spouse-rated and self-rated health predicts mortality better than using self-rated health alone (area under the curve, 0.77) (chi(2)(1) = 6.72, P = .009). Conclusions: Spouse ratings of health are at least as strongly predictive of mortality as self-rated health. This suggests that, when self-rated health is elicited as a prognostic indicator, spouse ratings can be used when self-ratings are unavailable. Both measures together may be more informative than either measure alone. C1 [Ayalon, Liat] Bar Ilan Univ, Louis & Gabi Weisfeld Sch Social Work, IL-52900 Ramat Gan, Israel.

SO BMC MEDICINE LA English DT Editorial Material ID GENOTYPE-CORRELATED SENSITIVITY; GROWTH-FACTOR RECEPTOR; LUNG-CANCER; BREAST-CANCER; KINASE INHIBITORS; MUTATIONS; RESISTANCE; CHEMOTHERAPY; TRASTUZUMAB; PREDICTORS AB It is becoming increasingly apparent that cancer drug therapies can only reach their full potential through appropriate patient selection. Matching drugs and cancer patients has proven to be a complex challenge, due in large part to the substantial molecular heterogeneity inherent to human cancers. This is not only a major hurdle to the improvement of the use of current treatments but also for the development of novel therapies and the ability to steer them to the relevant clinical indications. In this commentary we discuss recent studies from Kuo et al., published this month in BMC Medicine, in which they used a panel of cancer cell lines as a model for capturing patient heterogeneity at the genomic and proteomic level in order to identify potential biomarkers for predicting the clinical activity of a novel candidate chemotherapeutic across a patient population. The findings highlight the ability of a 'systems approach' to develop a better understanding of the properties of novel candidate therapeutics and to guide clinical testing and application.

In this study we examined one potential mechanism for regulating TGF-beta and IL-10 expression by HIV-specific suppressor CD8+ T cells. No overlap between TGF-beta, IL-10, and IFN-gamma cytokine production by HIV-specific CD8+ T cells was observed. TGF-beta positive and IL-10 positive cells were FOXP3 negative, CD25 negative, and displayed a heterogeneous surface expression of CD127. TGF-beta and IL-10 positive CD8+ T cells did not express CTLA-4. Nevertheless, CTLA-4 blockade resulted in a significant decrease in HIV-specific TGF-beta positive and IL-10 positive CD8+ T cell responses, and a concomitant increase in HIV-specific IFN-gamma positive CD8+ T cell responses. Depletion of CD4+ T cells abrogated the impact of CTLA-4 on HIV-specific TGF-beta positive and IL-10 positive CD8+ T cells. Our study suggests that CTLA-4 Signaling on CD4+ T cells regulates the inhibitory functions of the HIV-specific suppressor CD8+ T cells. C1 [Elrefaei, Mohamed; Burke, Candace M.; Baker, Chris A.

As in the parallel human imaging study [1], we contrasted the 3D condition to several 2D control conditions. The extraction of 3D shape from texture (3D SfT) involves both ventral and parietal regions, in addition to early visual areas. Strongest activation was observed in CIP, with decreasing strength towards the anterior part of the intraparietal sulcus (IPS). In the ventral stream 3D SfT sensitivity was observed in a ventral portion of TEO. The extraction of 3D shape from shading (3D SfS) involved predominantly ventral regions, such as V4 and a dorsal potion of TEO. These results are similar to those obtained earlier in human subjects and indicate that the extraction of 3D shape from texture is performed in both ventral and dorsal regions for both species, as are the motion and disparity cues, whereas shading is mainly processed in the ventral stream.

TI RNA Editing Genes Associated with Extreme Old Age in Humans and with Lifespan in C-elegans SO PLOS ONE LA English DT Article ID GENOME-WIDE ASSOCIATION; HUMAN LONGEVITY; CAENORHABDITIS-ELEGANS; EXCEPTIONAL LONGEVITY; MESSENGER-RNA; CENTENARIANS; INSULIN; GENOTYPE; POPULATION; DROSOPHILA AB Background: The strong familiality of living to extreme ages suggests that human longevity is genetically regulated. The majority of genes found thus far to be associated with longevity primarily function in lipoprotein metabolism and insulin/IGF-1 signaling. There are likely many more genetic modifiers of human longevity that remain to be discovered. Methodology/Principal Findings: Here, we first show that 18 single nucleotide polymorphisms (SNPs) in the RNA editing genes ADARB1 and ADARB2 are associated with extreme old age in a U. S. based study of centenarians, the New England Centenarian Study. We describe replications of these findings in three independently conducted centenarian studies with different genetic backgrounds (Italian, Ashkenazi Jewish and Japanese) that collectively support an association of ADARB1 and ADARB2 with longevity. Some SNPs in ADARB2 replicate consistently in the four populations and suggest a strong effect that is independent of the different genetic backgrounds and environments. To evaluate the functional association of these genes with lifespan, we demonstrate that inactivation of their orthologues adr-1 and adr-2 in C. elegans reduces median survival by 50%. We further demonstrate that inactivation of the argonaute gene, rde-1, a critical regulator of RNA interference, completely restores lifespan to normal levels in the context of adr-1 and adr-2 loss of function. Conclusions/Significance: Our results suggest that RNA editors may be an important regulator of aging in humans and that, when evaluated in C. elegans, this pathway may interact with the RNA interference machinery to regulate lifespan.

Twelve reasons for including bodily expressions in affective neuroscience SO PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY B-BIOLOGICAL SCIENCES LA English DT Article; Proceedings Paper CT Meeting on Computation of Emotions in Man and Machines CY APR, 2009 CL Royal Soc London, London, ENGLAND HO Royal Soc London ID DYNAMIC BODY EXPRESSIONS; NON-CONSCIOUS RECOGNITION; AUTISM SPECTRUM DISORDER; FACIAL EXPRESSIONS; ASPERGERS-SYNDROME; AMYGDALA THEORY; AFFECTIVE BLINDSIGHT; EMOTION PERCEPTION; BIOLOGICAL MOTION; FACE PERCEPTION AB Why bodies? It is rather puzzling that given the massive interest in affective neuroscience in the last decade, it still seems to make sense to raise the question 'Why bodies' and to try to provide an answer to it, as is the goal of this article. There are now hundreds of articles on human emotion perception ranging from behavioural studies to brain imaging experiments. These experimental studies complement decades of reports on affective disorders in neurological patients and clinical studies of psychiatric populations. The most cursory glance at the literature on emotion in humans, now referred to by the umbrella term of social and affective neuroscience, shows that over 95 per cent of them have used faces as stimuli. Of the remaining 5 per cent, a few have used scenes or auditory information including human voices, music or environmental sounds. But by far the smallest number has looked into whole-body expressions. As a rough estimate, a search on PubMed today, 1 May 2009, yields 3521 hits for emotion x faces, 1003 hits for emotion x music and 339 hits for emotion x bodies. When looking in more detail, the body x emotion category in fact yields a majority of papers on well-being, nursing, sexual violence or organ donation. But the number of cognitive and affective neuroscience studies of emotional body perception as of today is lower than 20. Why then have whole bodies and bodily expressions not attracted the attention of researchers so far? The goal of this article is to contribute some elements for an answer to this question. I believe that there is something to learn from the historical neglect of bodies and bodily expressions. I will next address some historical misconceptions about whole-body perception, and in the process I intend not only to provide an impetus for this kind of work but also to contribute to a better understanding of the significance of the affective dimension of behaviour, mind and brain as seen from the vantage point of bodily communication. Subsequent sections discuss available evidence for the neurofunctional basis of facial and bodily expressions as well as neuropsychological and clinical studies of bodily expressions.

TI A Truncating Mutation of TRAPPC9 Is Associated with Autosomal-Recessive Intellectual Disability and Postnatal Microcephaly SO AMERICAN JOURNAL OF HUMAN GENETICS LA English DT Article ID NONSYNDROMIC MENTAL-RETARDATION; NF-KAPPA-B; X-CHROMOSOME; GENE; NEUROGENESIS; DEFECT AB Although autosomal genes are increasingly recognized as important causes of intellectual disability, very few of them are known. We identified a genetic locus for autosomal-recessive nonsyndromic intellectual disability associated with variable postnatal microcephaly through homozygosity mapping of a consanguineous Israeli Arab family. Sequence analysis of genes in the candidate interval identified a nonsense nucleotide change in the gene that encodes TRAPPC9 (trafficking protein particle complex 9, also known as NIBP), which has been implicated in NF-kappa B activation and possibly in intracellular protein trafficking. TRAPPC9 is highly expressed in the postmitotic neurons of the cerebral cortex, and MRI analysis of affected patients shows defects in axonal connectivity. This suggests essential roles of TRAPPC9 in human brain development, possibly through its effect on NF-kappa B activation and protein trafficking in the postmitotic neurons of the cerebral cortex.

Among the various transcriptional coregulators with which HNF4 alpha interacts, peroxisome proliferation-activated receptor gamma(PPAR gamma) coactivator 1 alpha(PGC-1 alpha) represents a novel coactivator whose activation is unusually robust and whose binding mode appears to be distinct from that of canonical coactivators such as NCoA/SRC/p160 family members. To elucidate the potentially unique molecular mechanism of PGC-1 alpha recruitment, we have determined the crystal structure of HNF4 alpha in complex with a fragment of PGC-1 alpha containing all three of its LXXLL motifs. Despite the presence of all three LXXLL motifs available for interactions, only one is bound at the canonical binding site, with no additional contacts observed between the two proteins. However, a close inspection of the electron density map indicates that the bound LXXLL motif is not a selected one but an averaged structure of more than one LXXLL motif. Further biochemical and functional studies show that the individual LXXLL motifs can bind but drive only minimal transactivation. Only when more than one LXXLL motif is involved can significant transcriptional activity be measured, and full activation requires all three LXXLL motifs. These findings led us to propose a model wherein each LXXLL motif has an additive effect, and the multiple binding modes by HNF4 alpha toward the LXXLL motifs of PGC-1 alpha could account for the apparent robust activation by providing a flexible mechanism for combinatorial recruitment of additional coactivators and mediators.

TI Sickle cell disease and stroke SO BLOOD LA English DT Review ID IRON-CHELATION-THERAPY; TRANSCRANIAL DOPPLER; TRANSFUSION THERAPY; FETAL-HEMOGLOBIN; CORD BLOOD; POLYCYTHEMIA-VERA; THALASSEMIA MAJOR; RECURRENT STROKE; CEREBROVASCULAR-DISEASE; HYDROXYUREA TREATMENT AB Twenty-four percent of sickle cell disease (SCD) patients have a stroke by the age of 45 years. Blood transfusions decrease stroke risk in patients deemed high risk by transcranial Doppler. However, transcranial Doppler has poor specificity, and transfusions are limited by alloimmunization and iron overload. Transfusion withdrawal may be associated with an increased rebound stroke risk. Extended blood typing decreases alloimmunization in SCD but is not universally adopted. Transfusions for thalassemia begun in early childhood are associated with lower rates of alloimmunization than are seen in SCD, suggesting immune tolerance. Optimal oxygen transport efficiency occurs at a relatively low hematocrit for SCD patients because of hyperviscosity. Consequently, exchange rather than simple transfusions are more effective in improving oxygen transport efficiency, but the former are technically more demanding and require more blood units. Although viscosity is of importance in the noncerebral manifestations of SCD, inflammation may play a larger role than viscosity in the development of large-vessel stroke. The future of SCD stroke management lies in the avoidance of transfusion. Hydroxyurea and anti-inflammatory measures may reduce the need for transfusion. Recent genome-wide association studies may provide methods for modulating fetal hemoglobin production enough to attenuate stroke risk and other complications of SCD.

Most commonly used methods for identifying differentially expressed genes treat each time point as independent and ignore important correlations, including those within samples and between sampling times. Therefore they do not make full use of the information intrinsic to the data, leading to a loss of power. Results: We present a flexible random-effects model that takes such correlations into account, improving our ability to detect genes that have sustained differential expression over more than one time point. By modeling the joint distribution of the samples that have been profiled across all time points, we gain sensitivity compared to a marginal analysis that examines each time point in isolation. We assign each gene a probability of differential expression using an empirical Bayes approach that reduces the effective number of parameters to be estimated. Conclusions: Based on results from theory, simulated data, and application to the genomic data presented here, we show that BETR has increased power to detect subtle differential expression in time-series data. The open-source R package betr is available through Bioconductor. BETR has also been incorporated in the freely-available, open-source MeV software tool available from http:/www.tm4.org/mev.html.

TI Role of Sensitivity Analyses in Assessing Progression-Free Survival in Late-Stage Oncology Trials SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID MATTERS AB Sensitivity analysis is an important statistical technique that assesses whether the results of phase III trials are robust and likely to be generalizable. Until recently, sensitivity analyses were rarely included in phase III trials, and they remain poorly understood by many oncologists. Sensitivity analyses are critical to understanding the strength of conclusions made in the primary analysis of a late-stage clinical trial. They examine the influence of protocol design errors, unintended biases, deviations from assumptions underlying statistical models, and any unanticipated treatment delivery or practice patterns on trial results. In trials with complex or subjective end points, they also allow an understanding of the extent to which a positive outcome is driven by a single, possibly subjective, and therefore biased, element of an end point. The purposes of this article are to explain how sensitivity analyses are performed, to discuss areas of a clinical trial where sensitivity analyses should focus, and to illuminate the importance of this technique in the rigorous evaluation of late-stage clinical trial data, using specific examples. This article focuses on late-stage trials that use progression-free survival or time to progression as their primary end point, because sensitivity analyses are particularly important in these cases for which the end point is potentially subject to bias. Three sources of potential bias are explored: assessment time, symptomatic (ie, nonradiologic) disease progression, and missing data. For each source of potential bias, case studies are presented to highlight the role that sensitivity analyses play in determining whether the trial's conclusions are robust.

TI Evaluating the Combined Effect of Comorbidity and Prostate-Specific Antigen Kinetics on the Risk of Death in Men After Prostate-Specific Antigen Recurrence SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID CANCER-SPECIFIC MORTALITY; RADICAL PROSTATECTOMY; ANDROGEN SUPPRESSION; RADIATION-THERAPY; RANDOMIZED-TRIAL AB Purpose We examined whether time-dependent continuous prostate-specific antigen (PSA) velocity at recurrence was associated with all cause mortality (ACM) adjusting for comorbidity levels among men treated with definitive radiation therapy (RT) alone with or without androgen suppression therapy (AST) in the setting of a randomized controlled trial. Patients and Methods From 1995 to 2001, 206 men with localized, unfavorable prostate cancer were randomly assigned to receive RT alone or RT and AST combined. Cox multivariate regression analysis was performed to evaluate the relationship between PSA velocity at recurrence and ACM, adjusting for known prostate cancer prognostic factors, including Adult Comorbidity Evaluation 27 comorbidity level. Results With a median follow-up of 8.4 years, 89 biochemical recurrences and 74 ACM deaths occurred. Among all patients, higher PSA velocity was associated with increased ACM (hazard ratio [HR], 1.47; 95% CI, 1.07 to 1.44; P < .001) after adjusting for age, treatment arm, comorbidity score, and salvage AST. For 89 patients with biochemical recurrence, increasing PSA velocity at recurrence (HR, 1.60; 95% CI, 1.23 to 2.09; P <= .001) and moderate to severe comorbidity score (HR, 7.94; 95% CI, 1.55 to 40.52; P = .01) were associated with increased ACM. PSA velocity at recurrence was associated with significantly higher risk of ACM among patients with no or minimal comorbidity (P < .001), but not moderate to severe comorbidity (P = .12). Conclusion Rapid PSA velocity at recurrence is significantly associated with an increased risk of ACM among patients with no or minimal comorbidity but not moderate to severe comorbidity. These findings support judicious use of salvage AST, particularly in men with moderate to severe comorbidities, where prospective surveillance protocols are needed.

Patients and Methods In this phase II trial, 63 patients were treated with bevacizumab 15 mg/kg plus cisplatin 60 mg/m(2) and etoposide 120 mg/m(2), which was followed by bevacizumab alone until death or disease progression occurred. The primary end point was the proportion of patients alive at 6 months without disease progression (ie, progression-free survival [PFS]). Secondary end points included overall survival (OS), objective response rate, and toxicity. Correlative studies were performed to explore the relationship between baseline and changes in plasma vascular endothelial growth factor (VEGF), soluble cell adhesion molecules (ie, vascular cell adhesion molecule [VCAM], intercellular cell adhesion molecule [ICAM], and E-selectin) and basic fibroblast growth factor and outcome. Results The 6-month PFS was 30.2%, the median PFS was 4.7 months, and OS was 10.9 months. The response rate was 63.5%. The most common adverse event was neutropenia (57.8%). Only one patient had grade 3 pulmonary hemorrhage. Patients who had high baseline VCAM had a higher risk of progression or death compared with those who had low baseline VCAM levels. No relationships between outcome and any other biomarkers were seen. Conclusion The addition of bevacizumab to cisplatin and etoposide in patients with ED-SCLC results in improved PFS and OS relative to historical controls who received this chemotherapy regimen without bevacizumab. This regimen appears to be well tolerated and has minimal increase in toxicities compared with chemotherapy alone. Baseline VCAM levels predicted survival, but no other relationships among treatment, biomarkers, and outcome were identified. C1 Vanderbilt Univ, Nashville, TN USA.

Here we have captured and structurally elucidated a base-excision DNA repair enzyme, MutM, at the stage of initial encounter with a damaged nucleobase, 8-oxoguanine (oxoG), nested within a DNA duplex. Three structures of intrahelical oxoG-encounter complexes are compared with sequence-matched structures containing a normal G base in place of an oxoG lesion. Although the protein-DNA interfaces in the matched complexes differ by only two atoms-those that distinguish oxoG from G-their pronounced structural differences indicate that MutM can detect a lesion in DNA even at the earliest stages of encounter. All-atom computer simulations show the pathway by which encounter of the enzyme with the lesion causes extrusion from the DNA duplex, and they elucidate the critical free energy difference between oxoG and G along the extrusion pathway.

TI Long-range oncogenic activation of Igh-c-myc translocations by the Igh 3 ' regulatory region SO NATURE LA English DT Article ID HEAVY-CHAIN LOCUS; CLASS-SWITCH RECOMBINATION; B-CELL DEVELOPMENT; CHROMOSOMAL TRANSLOCATIONS; V(D)J RECOMBINATION; GENE AMPLIFICATION; TRANSGENIC MICE; DNA BREAKS; END; MECHANISM AB B-cell malignancies, such as human Burkitt's lymphoma, often contain translocations that link c-myc or other proto-oncogenes to the immunoglobulin heavy chain locus (IgH, encoded by Igh)(1). The nature of elements that activate oncogenes within such translocations has been a long-standing question. Translocations within Igh involve DNA double-strand breaks initiated either by the RAG1/2 endonuclease during variable, diversity and joining gene segment (V(D)J) recombination, or by activation-induced cytidine deaminase (AID, also known as AICDA) during class switch recombination (CSR)(2-4). V(D)J recombination in progenitor B (pro-B) cells assembles Igh variable region exons upstream of mu constant region (C mu) exons, which are the first of several sets of CH exons ('C(H) genes') within a CH locus that span several hundred kilobases (kb)(5,6). In mature B cells, CSR deletes C mu and replaces it with a downstream C(H) gene(6). An intronic enhancer (iE mu) between the variable region exons and C mu promotes V(D)J recombination in developing B cells(7). Furthermore, the Igh 3' regulatory region (Igh3' RR) lies downstream of the C(H) locus and modulates CSR by long-range transcriptional enhancement of C(H) genes(8-10). Transgenic mice bearing iE mu or Igh3' RR sequences fused to c-myc are predisposed to B lymphomas, demonstrating that such elements can confer oncogenic c-myc expression(11-16). However, in many B-cell lymphomas, Igh-c-myc translocations delete iE mu and place c-myc up to 200 kb upstream of the Igh3' RR(1). Here we address the oncogenic role of the Igh3' RR by inactivating it in two distinct mouse models for B-cell lymphoma with Igh-c-myc translocations. We show that the Igh3' RR is dispensable for pro-B-cell lymphomas with V( D) J recombination-initiated translocations, but is required for peripheral B-cell lymphomas with CSR-associated translocations. As the Igh3' RR is not required for CSR-associated Igh breaks or Igh-c-myc translocations in peripheral B-cell lymphoma progenitors, we conclude that this regulatory region confers oncogenic activity by long-range and developmental stage-specific activation of translocated c-myc genes.

TI Platelet Inhibition with Cangrelor in Patients Undergoing PCI. SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID ACUTE CORONARY SYNDROMES; PLACEBO-CONTROLLED TRIAL; ST-SEGMENT ELEVATION; ACUTE MYOCARDIAL-INFARCTION; PROCOAGULANT ACTIVITY; RECEPTOR ANTAGONISTS; RANDOMIZED-TRIAL; STENT THROMBOSIS; END-POINTS; CLOPIDOGREL AB Background: Cangrelor, a nonthienopyridine adenosine triphosphate analogue, is an intravenous blocker of the adenosine diphosphate receptor P2Y(sub 12). This agent might have a role in the treatment of patients who require rapid, predictable, and profound but reversible platelet inhibition. Methods: We performed a large-scale international trial comparing cangrelor with 600 mg of oral clopidogrel administered before percutaneous coronary intervention (PCI) in patients with acute coronary syndromes. The primary efficacy end point was a composite of death from any cause, myocardial infarction, or ischemia-driven revascularization at 48 hours. Results: We enrolled 8877 patients, and 8716 underwent PCI. At 48 hours, cangrelor was not superior to clopidogrel with respect to the primary composite end point, which occurred in 7.5% of patients in the cangrelor group and 7.1% of patients in the clopidogrel group (odds ratio, 1.05; 95% confidence interval [CI], 0.88 to 1.24; P=0.59). Likewise, cangrelor was not superior at 30 days. The rate of major bleeding (according to Acute Catheterization and Urgent Intervention Triage Strategy criteria) was higher with cangrelor, a difference that approached statistical significance (3.6% vs. 2.9%; odds ratio, 1.26; 95% CI, 0.99 to 1.60; P=0.06), but this was not the case with major bleeding (according to the Thrombolysis in Myocardial Infarction criteria) or severe or life-threatening bleeding (according to Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries criteria). A secondary exploratory end point of death from any cause, Q-wave myocardial infarction, or ischemia-driven revascularization showed a trend toward a reduction with cangrelor, but it was not significant (0.6% vs. 0.9%; odds ratio, 0.67; 95% CI, 0.39 to 1.14; P=0.14). Conclusions: Cangrelor, when administered intravenously 30 minutes before PCI and continued for 2 hours after PCI, was not superior to an oral loading dose of 600 mg of clopidogrel, administered 30 minutes before PCI, in reducing the composite end point of death from any cause, myocardial infarction, or ischemia-driven revascularization at 48 hours.

SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID PERCUTANEOUS CORONARY INTERVENTION; ST-SEGMENT ELEVATION; MYOCARDIAL-INFARCTION; ANTIPLATELET-THERAPY; ELUTING STENTS; CLOPIDOGREL; TRIAL; ASPIRIN; PRETREATMENT; PRASUGREL AB Background: Intravenous cangrelor, a rapid-acting, reversible adenosine diphosphate (ADP) receptor antagonist, might reduce ischemic events during percutaneous coronary intervention (PCI). Methods: In this double-blind, placebo-controlled study, we randomly assigned 5362 patients who had not been treated with clopidogrel to receive either cangrelor or placebo at the time of PCI, followed by 600 mg of clopidogrel. The primary end point was a composite of death, myocardial infarction, or ischemia-driven revascularization at 48 hours. Enrollment was stopped when an interim analysis concluded that the trial would be unlikely to show superiority for the primary end point. Results: The primary end point occurred in 185 of 2654 patients receiving cangrelor (7.0%) and in 210 of 2641 patients receiving placebo (8.0%) (odds ratio in the cangrelor group, 0.87; 95% confidence interval [CI], 0.71 to 1.07; P=0.17) (modified intention-to-treat population adjusted for missing data). In the cangrelor group, as compared with the placebo group, two prespecified secondary end points were significantly reduced at 48 hours: the rate of stent thrombosis, from 0.6% to 0.2% (odds ratio, 0.31; 95% CI, 0.11 to 0.85; P=0.02), and the rate of death from any cause, from 0.7% to 0.2% (odds ratio, 0.33; 95% CI, 0.13 to 0.83; P=0.02). There was no significant difference in the rate of blood transfusion (1.0% in the cangrelor group and 0.6% in the placebo group, P=0.13), though major bleeding on one scale was increased in the cangrelor group, from 3.5% to 5.5% (P<0.001), because of more groin hematomas. Conclusions: The use of periprocedural cangrelor during PCI was not superior to placebo in reducing the primary end point. The prespecified secondary end points of stent thrombosis and death were lower in the cangrelor group, with no significant increase in the rate of transfusion. Further study of intravenous ADP blockade with cangrelor may be warranted. (ClinicalTrials.gov number, NCT00385138.) N Engl J Med 2009;361:2330-41.

TI Improving follow-up of abnormal cancer screens using electronic health records: trust but verify test result communication SO BMC MEDICAL INFORMATICS AND DECISION MAKING LA English DT Article ID FECAL OCCULT-BLOOD; COMPLETE DIAGNOSTIC EVALUATION; COLORECTAL-CANCER; MALPRACTICE CLAIMS; UNITED-STATES; QUALITY; REASONS; ERRORS; CARE AB Background: Early detection of colorectal cancer through timely follow-up of positive Fecal Occult Blood Tests (FOBTs) remains a challenge. In our previous work, we found 40% of positive FOBT results eligible for colonoscopy had no documented response by a treating clinician at two weeks despite procedures for electronic result notification. We determined if technical and/or workflow-related aspects of automated communication in the electronic health record could lead to the lack of response. Methods: Using both qualitative and quantitative methods, we evaluated positive FOBT communication in the electronic health record of a large, urban facility between May 2008 and March 2009. We identified the source of test result communication breakdown, and developed an intervention to fix the problem. Explicit medical record reviews measured timely follow-up (defined as response within 30 days of positive FOBT) pre- and post-intervention. Results: Data from 11 interviews and tracking information from 490 FOBT alerts revealed that the software intended to alert primary care practitioners (PCPs) of positive FOBT results was not configured correctly and over a third of positive FOBTs were not transmitted to PCPs. Upon correction of the technical problem, lack of timely follow-up decreased immediately from 29.9% to 5.4% (p < 0.01) and was sustained at month 4 following the intervention. Conclusion: Electronic communication of positive FOBT results should be monitored to avoid limiting colorectal cancer screening benefits. Robust quality assurance and oversight systems are needed to achieve this. Our methods may be useful for others seeking to improve follow-up of FOBTs in their systems.

Little is known about the use of such medications and their effects on outcomes in clinical practice. Objective To investigate the use of the contraindicated/not-recommended agents enoxaparin and eptifibatide among dialysis patients undergoing percutaneous coronary intervention (PCI) and their association with outcomes. Design, Setting, and Participants Data from 829 US hospitals on 22 778 dialysis patients who underwent PCI between January 1, 2004, and August 31, 2008. Main Outcome Measures In-hospital bleeding and death. Results Five thousand eighty-four patients (22.3%) received a contraindicated antithrombotic; of these patients, 2375 (46.7%) received enoxaparin, 3261 (64.1%) received eptifibatide, and 552 (10.9%) received both. Compared with patients who did not receive a contraindicated antithrombotic, patients who did had higher rates of in-hospital bleeding (5.6% vs 2.9%; odds ratio [OR], 1.93; 95% confidence interval [CI], 1.66-2.23) and death (6.5% vs 3.9%; OR, 1.68; 95% CI, 1.46-1.95). After multivariable adjustment, patients receiving contraindicated antithrombotics had significantly higher risks of in-hospital bleeding (OR, 1.66; 95% CI, 1.43-1.92) and death (OR, 1.24; 95% CI, 1.04-1.48). In 10 158 patients matched by propensity scores, receipt of contraindicated antithrombotics remained significantly associated with in-hospital bleeding (OR, 1.63; 95% CI, 1.35-1.98) but not in-hospital death (OR, 1.15; 95% CI, 0.97-1.36). Conclusions In a sample of dialysis patients undergoing PCI, 22.3% received a contraindicated antithrombotic medication. In propensity-matched analysis, receipt of these medications was significantly associated with an increased risk of in-hospital major bleeding.

Healthy adults were vaccinated with CAIV (n = 10) or trivalent influenza vaccine (TIV) (n = 5). Shedding of vaccine strain influenza B was detected by culture in 6 of 10 CAN recipients; influenza A was also detected in one of these subjects. Viral shedding by quantitative RT-PCR was detected in 9 of 10 subjects. We detected a >= 2-fold increase in influenza-specific IgA in nasal wash in 80-100% of CAIV recipients following vaccination, but specific IgG increased in neither nasal wash nor saliva. Recipients of TIV had significant increases in specific serum IgG antibodies. Recipients of both CAIV and TIV had significant increases in IFN gamma-secreting peripheral blood mononuclear cells (PBMCs). PBMCs from subjects receiving CAN showed a higher proportion of functional, tissue-tropic T-cells (CD4+CD69+CD18+MIP1 alpha+) specific for homotypic and heterosubtypic strains of influenza by flow cytometry.

TI Psychological benefits 2 and 4 weeks after a single treatment with near infrared light to the forehead: a pilot study of 10 patients with major depression and anxiety SO BEHAVIORAL AND BRAIN FUNCTIONS LA English DT Article ID TRANSCRANIAL MAGNETIC STIMULATION; LEVEL LASER THERAPY; VISUAL-FIELD STIMULATION; CONTROLLED-TRIAL; DOUBLE-BLIND; ELECTROCONVULSIVE-THERAPY; RAYNAUDS-PHENOMENON; RAT-BRAIN; IRRADIATION; EFFICACY AB Background: Many studies have reported beneficial effects from the application of near-infrared (NIR) light photobiomodulation (PBM) to the body, and one group has reported beneficial effects applying it to the brain in stroke patients. We have reported that the measurement of a patient's left and right hemispheric emotional valence (HEV) may clarify data and guide lateralized treatments. We sought to test whether a NIR treatment could 1. improve the psychological status of patients, 2. show a relationship between immediate psychological improvements when HEV was taken into account, and 3. show an increase in frontal pole regional cerebral blood flow (rCBF), and 4. be applied without side effects. Methods: We gave 10 patients, (5 M/5 F) with major depression, including 9 with anxiety, 7 with a past history of substance abuse (6 with an opiate abuse and 1 with an alcohol abuse history), and 3 with post traumatic stress disorder, a baseline standard diagnostic interview, a Hamilton Depression Rating Scale (HAM-D), a Hamilton Anxiety Rating Scale (HAM-A), and a Positive and Negative Affect Scale (PANAS). We then gave four 4-minute treatments in a random order: NIR to left forehead at F3, to right forehead at F4, and placebo treatments (light off) at the same sites. Immediately following each treatment we repeated the PANAS, and at 2-weeks and at 4-weeks post treatment we repeated all 3 rating scales. During all treatments we recorded total hemoglobin (cHb), as a measure of rCBF with a commercial NIR spectroscopy device over the left and the right frontal poles of the brain. Results: At 2-weeks post treatment 6 of 10 patients had a remission (a score <= 10) on the HAMD and 7 of 10 achieved this on the HAM-A. Patients experienced highly significant reductions in both HAM-D and HAM-A scores following treatment, with the greatest reductions occurring at 2 weeks. Mean rCBF across hemispheres increased from 0.011 units in the off condition to 0.043 units in the on condition, for a difference of 0.032 (95% CI: -0.016, 0.080) units, though this result did not reach statistical significance. Immediately after treatment the PANAS improved to a significantly greater extent with NIR "on" relative to NIR "off" when a hemisphere with more positive HEV was treated than when one with more negative HEV was treated. We observed no side effects. Conclusion: This small feasibility study suggests that NIR-PBM may have utility for the treatment of depression and other psychiatric disorders and that double blind randomized placebo-controlled trials are indicated.

The catalytic Na,K-ATPase alpha subunit is not able to exit the ER or catalyze ion transport unless assembled with the beta subunit. However, requirements for the ER exit of the Na,K-ATPase beta subunit that plays an additional, ion-transport-independent, role in Intercellular adhesion are not clear. Exogenous beta(1) or beta(2) subunits expressed in renal MDCK cells replace endogenous beta(1) subunits in the alpha-beta complexes in the ER, resulting in a decrease in the amount of the alpha(1)-bound endogenous beta(1) subunits by 47-61% with no change in the amount of alpha(1) subunits. Disruption of the alpha(1)-beta association by mutations in defined alpha(1)-interacting regions of either beta(1) or beta(2) subunits results in the ER retention and rapid degradation of unassembled mutants. Hence, the ER quality control system allows export only of assembled alpha-beta complexes to the Golgi, thereby maintaining an equimolar ratio of alpha and beta subunits in the plasma membrane, whereas the number of alpha(1) subunits in the ER determines the amount of the alpha-beta complexes.

TI In vivo high-resolution fluorescence microendoscopy for ovarian cancer detection and treatment monitoring SO BRITISH JOURNAL OF CANCER LA English DT Article DE imaging; optical fibre; photodynamic therapy (PDT); benzoporphyrin-derivative monoacid ring A (BPD-MA) ID INTRAPERITONEAL PHOTODYNAMIC THERAPY; MONOACID RING-A; PHASE-II TRIAL; 5-AMINOLEVULINIC ACID; CONFOCAL MICROSCOPY; COMPUTED-TOMOGRAPHY; BARRETTS-ESOPHAGUS; EPITHELIAL ACINI; MODEL; CARCINOMATOSIS AB BACKGROUND: In patients with advanced ovarian cancer (OvCa), microscopic residual tumour nodules that remain after surgical debulking frequently escape detection by current treatment assessment methods and lead to disease recurrence. The aim of this study was to evaluate the use of high-resolution fibre-optic fluorescence imaging of the clinically approved photodynamic therapy (PDT) agent benzoporphyin-derivative monoacid ring A (BPD-MA) for detection of microscopic OvCa and for monitoring treatment response. METHODS: Our fluorescence microendoscope consists of a flexible imaging fibre coupled to a custom epi-fluorescence system optimised for imaging BPD-MA, which, after a single administration, serves as both an imaging agent and a light-activated therapeutic agent. After characterisation in an in vitro OvCa 3D model, we used the flexible imaging fibre to minimally invasively image the peritoneal cavity of a disseminated OvCa murine model using BPD-MA administered intraperitoneally (i.p.). To evaluate longitudinal changes in response to treatment, we compared sets of images obtained before and after PDT with those from untreated mice imaged at the same time points. RESULTS: By comparison with histopathology, we report an 86% sensitivity for tumour detection in vivo using the microendoscope. Using a custom routine to batch process-image data in the monitoring study, treated mice exhibited an average decrease of 58.8% in tumour volumes compared with an increase of 59.3% in untreated controls (P<0.05). CONCLUSIONS: Our findings indicate the potential of this approach as a reporter of treatment outcome that could aid in the rational design of strategies to mitigate recurrent OvCa.

METHODS: We have genotyped rs744154 in 9408 BRCA1 and 5632 BRCA2 mutation carriers from the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA) and assessed its association with breast cancer risk using a retrospective weighted cohort approach. RESULTS: We found no evidence of association with breast cancer risk for BRCA1 (per-allele HR: 0.98, 95% CI: 0.93-1.04, P = 0.5) or BRCA2 (per-allele HR: 0.97, 95% CI: 0.89-1.06, P = 0.5) mutation carriers. CONCLUSION: This SNP is not a significant modifier of breast cancer risk for mutation carriers, though weak associations cannot be ruled out.

TI A Gene Signature Predictive for Outcome in Advanced Ovarian Cancer Identifies a Survival Factor: Microfibril-Associated Glycoprotein 2 SO CANCER CELL LA English DT Article ID EXPRESSION PATTERNS; ENDOTHELIAL-CELLS; ADHESION; STATISTICS; CENTROSOME; INTEGRINS; INTERACTS; MAGP-2; TUMORS AB Advanced stage papillary serous tumors of the ovary are responsible for the majority of ovarian cancer deaths, yet the molecular determinants modulating patient survival are poorly characterized. Here, we identify and validate a prognostic gene expression signature correlating with survival in a series of microdissected serous ovarian tumors. Independent evaluation confirmed the association of a prognostic gene microfibril-associated glycoprotein 2 (MAGP2) with poor prognosis, whereas in vitro mechanistic analyses demonstrated its ability to prolong tumor cell survival and stimulate endothelial cell motility and survival via the alpha(V)beta(3) integrin receptor. Increased MAGP2 expression correlated with microvessel density suggesting a proangiogenic role in vivo. Thus, MAGP2 may serve as a survival-associated target.

CA CHARISMA Investigators TI Smoking, Clopidogrel, and Mortality in Patients With Established Cardiovascular Disease SO CIRCULATION LA English DT Article DE smoking; clopidogrel; mortality; cardiovascular disease ID ACUTE MYOCARDIAL-INFARCTION; CIGARETTE-SMOKING; ATHEROTHROMBOTIC EVENTS; THROMBOLYTIC THERAPY; SECONDARY PREVENTION; CORONARY; RISK; CESSATION; WOMEN; TRIAL AB Background-Smoking increases platelet aggregability and the degree of platelet inhibition by clopidogrel on ex vivo platelet function tests. Whether smoking status affects the relationship between clopidogrel and clinical outcomes is unknown. Methods and Results-We evaluated the relationship between smoking status (current smoker, former smoker, or never-smoker) and treatment with clopidogrel on the risk of all-cause, cardiovascular, and cancer mortality among the 12 152 participants from the CHARISMA (Clopidogrel for High Atherothrombotic Risk and Ischemic Stabilization, Management, and Avoidance) trial who had established cardiovascular disease. Current smoking was associated with an increase in all-cause ( adjusted hazard ratio [HR] 2.58, 95% confidence interval [CI] 1.85 to 3.60), cardiovascular (HR 2.26, 95% CI 1.48 to 3.45), and cancer (HR 3.56, 95% CI 1.96 to 6.46) mortality compared with never smoking. The impact of clopidogrel on mortality differed by smoking status (P for interaction = 0.018 for current smokers). Among current smokers, clopidogrel was associated with a reduction in all-cause mortality (HR 0.68, 95% CI 0.49 to 0.94); clopidogrel did not reduce all-cause mortality among former smokers (HR 0.95, 95% CI 0.75 to 1.19) or never-smokers (HR 1.14, 95% CI 0.83 to 1.58). A similar pattern was noted for cardiovascular mortality. As expected, no relationship was observed between clopidogrel and cancer mortality by smoking status. The risk of bleeding appeared to differ according to smoking status; randomized clopidogrel was associated with a significantly increased risk of severe or moderate bleeding (HR 1.62, P=0.04) among current smokers but a smaller and nonsignificant increase among never-smokers (HR 1.31, P=0.15). Conclusions-Clopidogrel therapy may be more effective in current smokers, but it may also confer a greater bleeding risk than in nonsmokers. Further studies are needed to investigate this possibility. (Circulation. 2009; 120:2337-2344.) C1 [Bhatt, Deepak L.] VA Boston Healthcare Syst, Boston, MA 02115 USA.

CA TIMI Study Grp TI Effect of Intensive Statin Therapy on Clinical Outcomes Among Patients Undergoing Percutaneous Coronary Intervention for Acute Coronary Syndrome PCI-PROVE IT: A PROVE IT-TIMI 22 (Pravastatin or Atorvastatin Evaluation and Infection Therapy-Thrombolysis In Myocardial Infarction 22) Substudy SO JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY LA English DT Article DE acute coronary syndrome; percutaneous coronary intervention; pleiotropic; statin ID RANDOMIZED CONTROLLED-TRIAL; ATHEROSCLEROSIS; EVENTS; ROSUVASTATIN; PROGRESSION; TARGETS AB Objectives The goal of this analysis was to determine whether intensive statin therapy, compared with moderate-dose statin therapy, leads to a reduction in major adverse cardiovascular events (MACE) among patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). Background When compared with moderate-dose statins, intensive statin therapy reduces MACE among patients with ACS. The role of intensive statin therapy specifically among patients who undergo PCI for ACS is unknown. Methods Outcomes were compared in 2,868 patients who underwent PCI for ACS just prior to enrollment in the PROVE IT-TIMI 22 (Pravastatin or Atorvastatin Evaluation and Infection Therapy-Thrombolysis In Myocardial Infarction 22) trial, which randomized patients to either atorvastatin 80 mg or pravastatin 40 mg daily. The incidence of the primary composite end point of all-cause mortality, myocardial infarction, unstable angina leading to hospitalization, and revascularization after 30 days and stroke was evaluated, as was the incidence of target vessel revascularization (TVR) and non-TVR during follow-up. Results Treatment with 80 mg atorvastatin reduced the incidence of the composite end point (21.5% vs. 26.5%, hazard ratio: 0.78, 95% confidence interval: 0.67 to 0.91, p = 0.002) and lowered the incidence of both TVR (11.4% vs. 15.4%, p = 0.001) and non-TVR (8.0% vs. 10.5%, p = 0.017) compared with 40 mg pravastatin. After adjusting for on-treatment serum low-density lipoprotein cholesterol and C-reactive protein concentrations, the odds of TVR with high-dose statin therapy remained significant (odds ratio: 0.74, p = 0.015) while the odds of non-TVR did not (odds ratio: 0.92, p = 0.55). Conclusions Among patients with ACS who undergo PCI, intensive statin therapy reduces MACE compared with moderate-dose statin therapy. The reduction in the incidence of TVR was independent of low-density lipoprotein cholesterol and C-reactive protein lowering and may therefore be due, at least in part, to a pleiotropic effect of high-dose statin therapy.

TI Unsuspected coagulopathy rarely prevents IV thrombolysis in acute ischemic stroke SO NEUROLOGY LA English DT Article ID TISSUE-PLASMINOGEN ACTIVATOR; RT-PA STROKE; SAFE IMPLEMENTATION; PATIENT ELIGIBILITY; TPA THERAPY; SITS-MOST; ALTEPLASE; REASONS; ASSOCIATION; GUIDELINES AB Background: American Heart Association/American Stroke Association guidelines recommend initiating treatment with IV tissue plasminogen activator (tPA) in acute ischemic stroke patients without suspected coagulopathy prior to availability of clotting results; however, little or no data support this practice. We sought to identify how often blood clotting abnormalities were responsible for withholding IV tPA at our institution. Methods: We conducted a retrospective review of our prospectively acquired Get With the Guidelines Stroke database from January 2003 to April 2008. All patients underwent clinical evaluation by a neurologist, diagnostic neuroimaging, and laboratory testing on admission. We classified patients with absolute contraindications to IV tPA as ineligible, and those with warnings/relative contraindications or potentially treatable factors as potentially eligible. Results: Of 2,335 considered for analysis, 470 (20.1%) patients presented to our emergency department (ED) within 3 hours. Among these, 147 (31.3%) received IV tPA in our ED, 102 (21.7%) had an absolute contraindication, and 221 (47%) had a reason to consider withholding tPA. Only 30/470 (6.4%) of potential thrombolysis patients were discovered to have international normalized ratio >= 1.7 or platelets <= 100,000/mu L, and of these, 28 were suspected a priori due to known coagulopathy from medication or illness. Only 2/470 (0.4%) patients had an unsuspected coagulopathy that ultimately prevented thrombolysis. Conclusions: Based on the experience of a large thrombolysis referral center, stroke patients without suspected clotting abnormality can safely begin thrombolytic therapy before clotting results are available. These data support the current practice guidelines, and may reassure clinicians that the benefits of early administration greatly outweigh the risks due to an unsuspected bleeding diathesis.

In addition, chronic inflammation and infection have been increasingly recognized for their roles in cancer. Nevertheless, the mechanisms by which bacterial infections can initiate SC-mediated tumorigenesis remain elusive. Using a Drosophila model of gut pathogenesis, we show that intestinal infection with Pseudomonas aeruginosa, a human opportunistic bacterial pathogen, activates the c-Jun N-terminal kinase (JNK) pathway, a hallmark of the host stress response. This, in turn, causes apoptosis of enterocytes, the largest class of differentiated intestinal cells, and promotes a dramatic proliferation of SCs and progenitors that serves as a homeostatic compensatory mechanism to replenish the apoptotic enterocytes. However, we find that this homeostatic mechanism can lead to massive over-proliferation of intestinal cells when infection occurs in animals with a latent oncogenic form of the Ras1 oncogene. The affected intestines develop excess layers of cells with altered apicobasal polarity reminiscent of dysplasia, suggesting that infection can directly synergize with the genetic background in predisposed individuals to initiate SC-mediated tumorigenesis. Our results provide a framework for the study of intestinal bacterial infections and their effects on undifferentiated and mature enteric epithelial cells in the initial stages of intestinal cancer. Assessment of progenitor cell responses to pathogenic intestinal bacteria could provide a measure of predisposition for apoptotic enterocyte-assisted intestinal dysplasias in humans.

TI Activation of innate and humoral immunity in the peripheral nervous system of ALS transgenic mice SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE innate immunity; macrophage; peripheral nervous system; neuroimmunology; amyotrophic lateral sclerosis ID AMYOTROPHIC-LATERAL-SCLEROSIS; MOUSE MODEL; WALLERIAN DEGENERATION; DISEASE PROGRESSION; INHERITED ALS; MOTOR-NEURONS; FAMILIAL ALS; COMPLEMENT; INJURY; CELLS AB During injury to the nervous system, innate immune cells mediate phagocytosis of debris, cytokine production, and axon regeneration. In the neuro-degenerative disease amyotrophic lateral sclerosis (ALS), innate immune cells in the CNS are activated. However, the role of innate immunity in the peripheral nervous system (PNS) has not been well defined. In this study, we characterized robust activation of CD169/CD68/Iba1+ macrophages throughout the PNS in mutant SOD1(G93A) and SOD1(G37R) transgenic mouse models of ALS. Macrophage activation occurred pre-symptomatically, and expanded from focal arrays within nerve bundles to a tissue-wide distribution following symptom onset. We found a striking dichotomy for immune cells within the spinal cord and PNS. Flow cytometry and GFP bone marrow chimeras showed that spinal cord microglia were mainly tissue resident derived, dendritic-like cells, whereas in peripheral nerves, the majority of activated macrophages infiltrated from the circulation. Humoral antibodies and complement localized to PNS tissue in tandem with macrophage recruitment, and deficiency in complement C4 led to decreased macrophage activation. Therefore, cross-talk between nervous and immune systems occurs throughout the PNS during ALS disease progression. These data reveal a progressive innate and humoral immune response in peripheral nerves that is separate and distinct from spinal cord immune activation in ALS transgenic mice.

Although several techniques exist for measuring cerebral oxygenation in vivo, the most widely accepted techniques offer limited spatial resolution. We have developed a confocal imaging system for minimally invasive measurement of oxygen tension (pO(2)) in cerebral microvessels with high spatial and temporal resolution. The system relies on the phosphorescence quenching method using exogenous porphyrin-based dendritic oxygen probes. Here we present high-resolution phosphorescence images of cortical microvasculature and temporal pO(2) profiles from multiple locations in response to varied fraction of inspired oxygen and functional activation.

Our aim was to compare the effects of moderate consumption of fructose-containing and non-caloric sweetened beverages on feeding behavior, metabolic and serum lipid profiles. and hepatic histology and serum liver enzymes, in rats. Behavioral tests determined preferred ( 12.5-15%) concentrations of solutions of agave, fructose, high fructose corn syrup (HFCS), a combination of HFC5 and Hoodia (a putative appetite suppressant), or the non-caloric sweetener Stevia (n = 5/gp). HFCS intake was highest, in preference and self-administration tests. Groups (n = 10/gp) were then assigned to one of the sweetened beverages or water as the sole source of liquid at night (3 nights/wk, 10 wks). Although within the normal range, serum cholesterol was higher in the fructose and HFCS groups, and serum triglycerides were higher in the Agave, HFCS, and HFCS/Hoodia groups (vs. water-controls, p < 0.05). Liver histology was normal in all groups with no evidence of steatosis, inflammation, or fibrosis; however serum alanine aminotransferase was higher in the fructose and HFCS groups (vs. water-controls, p < 0.05). Serum inflammatory marker levels were comparable among Stevia, agave. fructose, HFCS. and water-consuming groups, however levels of IL-6 were significantly lower in association with the ingestion of Hoodia. There were no differences in terminal body weights, or glucose tolerance assessed by 120-min IVGTTs performed at the end of the 10-week regimen. We conclude that even moderate consumption of fructose-containing liquids may lead to the onset of unfavorable changes in the plasma lipid profile and one marker of liver health. independent of significant effects of sweetener consumption on body weight.

The Bcl-2 associated athanogene 1M (Bag-1M) is known to downregulate the DNA binding by the GR. Also, Bag-1M interacts with the ATPase domain of Hsp70 to modulate the release of the Substrate from Hsp70. In this study, we demonstrate that ATP hydrolysis enhances Bag-1M-n-tediated inhibition of the DNA binding by the GR. However, the inhibitory effect of Bag-1M was abolished when the intracellular ATP was depleted. In addition, a Bag-1M mutant lacking the interaction with Hsp70 did not influence the GR to bind DNA, suggesting the interaction of Bag-1M with Hsp70 in needed for its negative effect. These results indicate that ATP hydrolysis is essential for Bag-1M-mediated inhibition of the DNA binding by the GR and Hsp70 is a mediator for this process. (C) 2009 Elsevier Inc.

Design Observational study. Main outcome measures Total value of coins ingested and number of incidents of coins versus other objects swallowed, measured before and after the stock market crash of October 2008. Results Eighteen objects, including 11 coins, were ingested (NASDAQ ( numismatic and sundry detritus acquired) composite of 18). The total value of the 11 coins swallowed was $1.03 (FTSE 100 (fraction of the US$ or 100 cents) index of 103). The pecuniary extraction ratio ( PE ratio) was 0.57 (9/16). Comparing values for a period before and after October 2008, the mean monthly NASDAQ composite (0.41 (SD 0.67) v 0.5 (0.85), P=0.75), FTSE 100 index in cents (2.3 (6.8) v 3.1 (7.8), P=0.77), and PE ratio (0.54 (0.52) v 0.66 (0.29), P=0.50) did not change. The mean end-of-month closing value of the Dow Jones, however, decreased significantly (12537 (841.4) v 8388 (699.8), P<0.001) Conclusion There was no detectable difference in the total value of coins ingested, or ratio of coins to other objects swallowed, before or after a massive stock market crash.

The PF-LHA contains wake-active neurons that are quiescent during non-REM sleep and in the case of neurons expressing the peptide hypocretin (HCRT), quiescent during both non-REM and REM sleep. Adenosine is an endogenous sleep factor and recent evidence suggests that adenosine via A(1) receptors may act on PF-LHA neurons to promote sleep. We examined the effects of bilateral activation as well as blockade of A(1) receptors in the PF-LHA on sleep wakefulness in freely behaving rats. The sleep-wake profiles of male Wistar rats were recorded during reverse microdialysis perfusion of artificial cerebrospinal fluid (aCSF) and two doses of adenosine A(1) receptor antagonist, 1,3-dipropyl-8-phenylxanthine (CPDX; 5 mu M and 50 mu M) or A(1) receptor agonist, N-6-cyclopentyladenosine (CPA; 5 mu M and 50 mu M) into the PF-LHA for 2 h followed by 4 h of aCSF perfusion. CPDX perfused into the PF-LHA during lights-on phase produced arousal (F=7.035, p<0.001) and concomitantly decreased both non-REM (F=7.295, p<0.001) and REM sleep (F=3.456, p<0.004). In contrast, CPA perfused into the PF-LHA during lights-off phase significantly suppressed arousal (F=7.891,p<0.001) and increased non-REM (F = 8.18, p <0.001) and REM sleep (F = 30.036, p < 0.001). These results suggest that PF-LHA is one of the sites where adenosine, acting via A(1) receptors, inhibits PF-LHA neurons to promote sleep. Published by Elsevier B.V.

TI Amyotrophic Lateral Sclerosis-linked Mutant SOD1 Sequesters Hu Antigen R (HuR) and TIA-1-related Protein (TIAR) IMPLICATIONS FOR IMPAIRED POST-TRANSCRIPTIONAL REGULATION OF VASCULAR ENDOTHELIAL GROWTH FACTOR SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID MESSENGER-RNA STABILITY; 3' UNTRANSLATED REGION; AU-RICH ELEMENTS; GROWTH-FACTOR; OXIDATIVE STRESS; BINDING PROTEINS; STABILIZATION; APOPTOSIS; BCL-2; GENE AB Down-regulation of vascular endothelial growth factor (VEGF) in the mouse leads to progressive and selective degeneration of motor neurons similar to amyotrophic lateral sclerosis (ALS). In mice expressing ALS-associated mutant superoxide dismutase 1 (SOD1), VEGF mRNA expression in the spinal cord declines significantly prior to the onset of clinical manifestations. In vitro models suggest that dysregulation of VEGF mRNA stability contributes to that decline. Here, we show that the major RNA stabilizer, Hu Antigen R (HuR), and TIA-1-related protein (TIAR) colocalize with mutant SOD1 in mouse spinal cord extracts and cultured glioma cells. The colocalization was markedly reduced or abolished by RNase treatment. Immunoanalysis of transfected cells indicated that colocalization occurred in insoluble aggregates and inclusions. RNA immunoprecipitation showed a significant loss of VEGF mRNA binding to HuR and TIAR in mutant SOD1 cells, and there was marked depletion of HuR from polysomes. Ectopic expression of HuR in mutant SOD1 cells more than doubled the mRNA half-life of VEGF and significantly increased expression to that of wild-type SOD1 control. Cellular effects produced by mutant SOD1, including impaired mitochondrial function and oxidative stress-induced apoptosis, were reversed by HuR in a gene dose-dependent pattern. In summary, our findings indicate that mutant SOD1 impairs post-transcriptional regulation by sequestering key regulatory RNA-binding proteins. The rescue effect of HuR suggests that this impairment, whether related to VEGF or other potential mRNA targets, contributes to cytotoxicity in ALS.

In humans, hematopoietic stem cells (HSCs) express MCL-1 at the highest level in response to FMS-like tyrosine kinase-3 (FLT3) signaling. We here show that this FLT3-dependent stem cell maintenance system also plays a critical role in survival of leukemic stem cells (LSCs) in acute myeloid leukemia (AML). The CD34(+)CD38-LSC fraction expresses high levels of FLT3 as well as MCL-1, even compared with normal HSCs. Treatment with FLT3 ligand induced further MCL-1 up-regulation in LSCs in all AML cases tested. Interestingly, the group of samples expressing the highest levels of MCL-1 constituted AML with FLT3-internal tandem duplications (ITD). In FLT3-ITD AML cell lines, cells expressed a high level of MCL-1, and an inhibition of MCL-1 induced their apoptotic cell death. A tyrosine kinase inhibitor suppressed MCL-1 expression, and induced apoptosis that was reversed by the enforced MCL-1 expression. Finally, transduction of FLT3-ITD into HSCs strongly activated MCL-1 expression through its signal transducer and activator of transcription 5 (STAT5)docking domains. This effect was completely abrogated when STAT5 activation was blocked. Thus, the acquisition of FLT3-ITD ensures LSC survival by up-regulating MCL-1 via constitutive STAT5 activation that is independent of wildtype FLT3 signaling.

Zhu, Jian-Kang TI In vitro reconstitution of an abscisic acid signalling pathway SO NATURE LA English DT Article ID PROTEIN PHOSPHATASES; GENE-EXPRESSION; ARABIDOPSIS; STRESS; KINASE; ABA; IDENTIFICATION; TRANSDUCTION; GERMINATION; RECEPTORS AB The phytohormone abscisic acid (ABA) regulates the expression of many genes in plants; it has critical functions in stress resistance and in growth and development(1-7). Several proteins have been reported to function as ABA receptors(8-13), and many more are known to be involved in ABA signalling(3,4,14). However, the identities of ABA receptors remain controversial and the mechanism of signalling from perception to downstream gene expression is unclear(15,16). Here we show that by combining the recently identified ABA receptor PYR1 with the type 2C protein phosphatase (PP2C) ABI1, the serine/threonine protein kinase SnRK2.6/OST1 and the transcription factor ABF2/AREB1, we can reconstitute ABA-triggered phosphorylation of the transcription factor in vitro. Introduction of these four components into plant protoplasts results in ABA-responsive gene expression. Protoplast and test-tube reconstitution assays were used to test the function of various members of the receptor, protein phosphatase and kinase families. Our results suggest that the default state of the SnRK2 kinases is an autophosphorylated, active state and that the SnRK2 kinases are kept inactive by the PP2Cs through physical interaction and dephosphorylation. We found that in the presence of ABA, the PYR/PYL (pyrabactin resistance 1/PYR1-like) receptor proteins can disrupt the interaction between the SnRK2s and PP2Cs, thus preventing the PP2C-mediated dephosphorylation of the SnRK2s and resulting in the activation of the SnRK2 kinases. Our results reveal new insights into ABA signalling mechanisms and define a minimal set of core components of a complete major ABA signalling pathway.

CA AIDS Clinical Trials Grp Study TI Abacavir-Lamivudine versus Tenofovir-Emtricitabine for Initial HIV-1 Therapy SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID RANDOMIZED-TRIAL; INFECTED ADULTS; NAIVE PATIENTS; LOPINAVIR/RITONAVIR; ZIDOVUDINE; DF; EFAVIRENZ; EFFICACY; SAFETY AB BACKGROUND The use of fixed-dose combination nucleoside reverse-transcriptase inhibitors (NRTIs) with a nonnucleoside reverse-transcriptase inhibitor or a ritonavir-boosted protease inhibitor is recommended as initial therapy in patients with human immunodeficiency virus type 1 (HIV-1) infection, but which NRTI combination has greater efficacy and safety is not known. METHODS In a randomized, blinded equivalence study involving 1858 eligible patients, we compared four once-daily anti-retroviral regimens as initial therapy for HIV-1 infection: abacavir-lamivudine or tenofovir disoproxil fumarate (DF)-emtricitabine plus efavirenz or ritonavir-boosted atazanavir. The primary efficacy end point was the time from randomization to virologic failure (defined as a confirmed HIV-1 RNA level >= 1000 copies per milliliter at or after 16 weeks and before 24 weeks, or = 200 copies per milliliter at or after 24 weeks). RESULTS A scheduled interim review by an independent data and safety monitoring board showed significant differences in virologic efficacy, according to the NRTI combination, among patients with screening HIV-1 RNA levels of 100,000 copies per milliliter or more. At a median follow-up of 60 weeks, among the 797 patients with screening HIV-1 RNA levels of 100,000 copies per milliliter or more, the time to virologic failure was significantly shorter in the abacavir-lamivudine group than in the tenofovir DF-emtricitabine group (hazard ratio, 2.33; 95% confidence interval, 1.46 to 3.72; P<0.001), with 57 virologic failures (14%) in the abacavir-lamivudine group versus 26 (7%) in the tenofovir DF-emtricitabine group. The time to the first adverse event was also shorter in the abacavir-lamivudine group (P<0.001). There was no significant difference between the study groups in the change from the baseline CD4 cell count at week 48. CONCLUSIONS In patients with screening HIV-1 RNA levels of 100,000 copies per milliliter or more, the times to virologic failure and the first adverse event were both significantly shorter in patients randomly assigned to abacavir-lamivudine than in those assigned to tenofovir DF-emtricitabine.

TI Telomerase deficiency and telomere dysfunction inhibit mammary tumors induced by polyomavirus middle T oncogene SO ONCOGENE LA English DT Article DE telomerase; telomeres; PyMT; MUC1; mammary carcinoma ID NORMAL HUMAN-CELLS; LIFE-SPAN; REVERSE-TRANSCRIPTASE; TRANSGENIC MICE; IMMORTAL CELLS; CANCER; TUMORIGENESIS; MOUSE; CARCINOGENESIS; CARCINOMA AB Mice transgenic for MUC1 (mucin 1) and polyomavirus middle T (PyMT) develop mammary carcinomas within 15 weeks with 100% penetrance. PyMT-induced mammary tumorigenesis is closely correlated with robust telomerase expression and activity. To assess the role of telomerase activation and telomere maintenance in mammary carcinoma tumorigenesis, we generated mice expressing MUC1 and PyMT (MMT mice) but deficient in the telomerase RNA component, mTerc, on the C57BL/6 background. Successive generational intercrosses of mTerc(-/-)MMT mice produced cohorts with progressively shorter telomeres that were audited for mammary tumor formation. Relative to MMT (N=14) and G0 mTerc(+/-) female controls (G0=14), mTerc(-/-)MMT females (G1=11, G2=15, G3=15 and G4=5) showed decreased tumor volumes and increased tumor latency-MMT=95.6 days; G0 mTerc(+/-) MMT=98.6 days versus G1, G2, G3 and G4 mTerc(-/-)MMT mice with latencies of 122.6, 138.9, 140.7 and 220.9 days, respectively (controls versus G1-G4, P<0.005). The progressive impairment of lung metastasis was also observed with each successive mTerc(-/-)MMT generation. The impairment of tumorigenesis was associated with decreased proliferation of mammary epithelial and tumor cells and increased apoptosis of tumor cells. Together, these results indicate that, in the setting of viral oncoprotein mammary tumorigenesis, telomerase-dependent telomere maintenance facilitates the formation and metastatic progression of mammary tumors.

Methodology/Principal Findings: We demonstrated a similar level of sensitivity in gene detection between matched fresh-frozen (FF) and FFPE samples, with the number and overlap of probes detected in the FFPE samples being approximately 88% and 95% of that in the corresponding FF samples, respectively; 74% of the differentially expressed probes overlapped between the FF and FFPE pairs. The WG-DASL assay is also able to detect 1.3-1.5 and 1.5-2-fold changes in intact and FFPE samples, respectively. The dynamic range for the assay is,3 logs. Comparing the WG-DASL assay with an in vitro transcription-based labeling method yielded fold-change correlations of R 2,0.83, while fold-change comparisons with quantitative RT-PCR assays yielded R(2)similar to 0.86 and R(2)similar to 0.55 for intact and FFPE samples, respectively. Additionally, the WG-DASL assay yielded high self-correlations (R(2)> 0.98) with low intact RNA inputs ranging from 1 ng to 100 ng; reproducible expression profiles were also obtained with 250 pg total RNA (R(2)> 0.92), with,71% of the probes detected in 100 ng total RNA also detected at the 250 pg level. When FFPE samples were assayed, 1 ng total RNA yielded self-correlations of R(2)similar to 0.80, while still maintaining a correlation of R(2)similar to 0.75 with standard FFPE inputs (200 ng). Conclusions/Significance: Taken together, these results show that WG-DASL assay provides a reliable platform for genome-wide expression profiling in archived materials. It also possesses utility within clinical settings where only limited quantities of samples may be available (e.g. microdissected material) or when minimally invasive procedures are performed (e.g. biopsied specimens).

The HomB encoded outer membrane protein was shown to contribute to the proinflammatory properties of H. pylori and also to be involved in bacterial adherence. This study investigated the distribution of homB and homA genes in 455 H. pylori strains from East Asian and Western countries, and carried out sequence comparison and phylogenetic analyses. Results: Both homB and homA genes were heterogeneously distributed worldwide, with a marked difference between East Asian and Western strains. Analysis of homB and homA sequences revealed diversity regarding the number of copies and their genomic localization, with East Asian and Western strains presenting different genotypes. Moreover, homB and homA sequence analysis suggests regulation by phase variation. It also indicates possible recombination events, leading to gene duplication or homB/homA conversion which may as well be implicated in the regulation of these genes. Phylogenetic reconstruction of homB and homA revealed clustering according to the geographic origin of strains. Allelic diversity in the middle region of the genes was observed for both homB and homA, although there was no correlation between any allele and disease. For each gene, a dominant worldwide allele was detected, suggesting that homB/homA allelic variants were independent of the geographical origin of the strain. Moreover, all alleles were demonstrated to be expressed in vivo. Conclusion: Overall, these results suggest that homB and homA genes are good candidates to be part of the pool of H. pylori OMPs implicated in host-bacteria interface and also contributing to the generation of antigenic variability, and thus involved in H. pylori persistence.

Patient self-reporting has been proposed as an additional data source, but the implications of such a shift are not understood. Patients with lung cancer receiving chemotherapy and their clinicians independently reported six CTCAE symptoms and Karnofsky Performance Status longitudinally at sequential office visits. To compare how patient's vs clinician's reports relate to sentinel clinical events, a time-dependent Cox regression model was used to measure associations between reaching particular CTCAE grade severity thresholds with the risk of death and emergency room visits. To measure concordance of CTCAE reports with indices of daily health status, Kendall tau rank correlation coefficients were calculated for each symptom with EuroQoL EQ-5D questionnaire and global question scores. Statistical tests were two-sided. A total of 163 patients were enrolled for an average of 12 months (range = 1-28 months), with a mean of 11 visits and 67 (41%) deaths. CTCAE reports were submitted by clinicians at 95% of visits and by patients at 80% of visits. Patients generally reported symptoms earlier and more frequently than clinicians. Statistically significant associations with death and emergency room admissions were seen for clinician reports of fatigue (P < .001), nausea (P = .01), constipation (P = .038), and Karnofsky Performance Status (P < .001) but not for patient reports of these items. Higher concordance with EuroQoL EQ-5D questionnaire and global question scores was observed for patient-reported symptoms than for clinician-reported symptoms. Longitudinally collected clinician CTCAE assessments better predict unfavorable clinical events, whereas patient reports better reflect daily health status. These perspectives are complementary, each providing clinically meaningful information. Inclusion of both types of data in treatment trial results and drug labels appears to be warranted.

TI Perspective: Physician Leadership in Quality SO ACADEMIC MEDICINE LA English DT Article AB While advances in biomedicine are awesome, progress in patient safety and quality of care has proven slow and arduous. One factor contributing to the labored progress is the paucity of physician-leaders who can help advance the science and practice of quality and safety. This limited talent pool, which has particularly serious consequences in academic medical centers (AMCs), stems from insufficient training in quality and safety, which in turn owes to our collective failure to view the delivery of health care as a science. Even when AMCs have trained and skilled quality and safety leaders, the infrastructure to support their work is deficient, with poorly defined job descriptions, competing responsibilities, and limited formal roles in the medical school compared with the hospital. Though there is limited empiric evidence to guide recommendations, the authors support four initiatives to accelerate national progress on quality and safety: (1) invest in quality and safety science, (2) revise quality and safety governance in AMCs, and (3) integrate roles within the hospital and medical school. Many of these shortcomings can be addressed by creating a newly integrated role: the vice dean for quality and hospital director of quality and safety. For AMCs to achieve significant improvements in quality and safety, they must invest in physician-leaders and in the support these leaders need to carry out their educational and operational roles.

TI Restructuring Within an Academic Health Center to Support Quality and Safety: The Development of the Center for Quality and Safety at the Massachusetts General Hospital SO ACADEMIC MEDICINE LA English DT Article AB Recent focus on the need to improve the quality and safety of health care has created new challenges for academic health centers (AHCs). Whereas previously quality was largely assumed, today it is increasingly quantifiable and requires organized systems for improvement. Traditional structures and cultures within AHCs, although well suited to the tripartite missions of teaching, research, and clinical care, are not easily adaptable to the tasks of measuring, reporting, and improving quality. Here, the authors use a case study of Massachusetts General Hospital's efforts to restructure quality and safety to illustrate the value of beginning with a focus on organizational culture, using a systematic process of engaging clinical leadership, developing an organizational framework dependent on proven business principles, leveraging focus events, and maintaining executive dedication to execution of the initiative. The case provides a generalizable example for AHCs of how applying explicit management design can foster robust organizational change with relatively modest incremental financial resources.

TI The Department of Veterans Affairs National Quality Scholars Fellowship Program: Experience From 10 Years of Training Quality Scholars SO ACADEMIC MEDICINE LA English DT Article AB The Department of Veterans Affairs (VA) National Quality Scholars Fellowship Program (VAQS) was established in 1998 as a postgraduate medical education fellowship to train physicians in new methods of improving the quality and safety of health care for veterans and the nation. The VAQS curriculum is based on adult learning theory, with a national core curriculum of face-to-face components, technologically mediated distance learning components, and a unique local curriculum that draws from the strengths of regional resources. VAQS has established strong ties with other VA programs. Fellows' research and quality improvement projects are integrated with local and regional VA leaders' priorities, enhancing the relevance and visibility of the fellows' efforts and promoting recruitment of fellows to VA positions. VAQS has enrolled 98 fellows since 1999; 75 have completed the program and 24 are currently enrolled. Fellowship graduates have pursued a variety of career paths: 17% are continuing training (most in VA), 31% hold a VA faculty/staff position, 66% are academic faculty, and 80% conduct clinical or research work related to health care improvement. Graduates have held leadership positions in VA, Department of Defense, academic medicine, and public health agencies. Combining knowledge about the improvement of health care with adult learning strategies, distance learning technologies, face-to-face meetings, local mentorship, and experiential projects has been successful in improving care in VA and preparing physicians to participate in, study, and lead the improvement of health care quality and safety.

TI Remediation of the Deficiencies of Physicians Across the Continuum From Medical School to Practice: A Thematic Review of the Literature SO ACADEMIC MEDICINE LA English DT Review AB Despite widespread endorsement of competency-based assessment of medical trainees and practicing physicians, methods for identifying those who are not competent and strategies for remediation of their deficits are not standardized. This literature review describes the published studies of deficit remediation at the undergraduate, graduate, and continuing medical education levels. Thirteen studies primarily describe small, single-institution efforts to remediate deficient knowledge or clinical skills of trainees or below-standard-practice performance of practicing physicians. Working from these studies and research from the learning sciences, the authors propose a model that includes multiple assessment tools for identifying deficiencies, individualized instruction, deliberate practice followed by feedback and reflection, and reassessment. The findings of the study reveal a paucity of evidence to guide best practices of remediation in medical education at all levels. There is an urgent need for multiinstitutional, outcomes-based research on strategies for remediation of less than fully competent trainees and physicians with the use of long-term follow-up to determine the impact on future performance.

Study design: This is a prospective repeated measures, mixed methods observational study. Sixty-five women who smoked prior to pregnancy were recruited at delivery and surveyed at 2, 6, 12, and 24 weeks postpartum; in-depth interviews were conducted when participants reported smoking. Results: Fifty-two percent self identified as White, non-Hispanic. Forty-seven percent resumed smoking by 24 weeks postpartum. Women who had returned to smoking by 24 weeks had a significantly larger decrease in perceived smoking-specific support than women who remained abstinent (p<0.001). By 24-week postpartum follow-up, only 24% of women reported that an obstetric clinician had discussed how to quit/stay quit. When qualitatively interviewed, more than half of women reported having no one to support them to stay quit or quit smoking. Conclusion: Following delivery, women lack needed smoking-specific support. Decline in perceived smoking-specific support from family and friends is associated with postpartum smoking resumption.

Using a managed care database (PharMetrics; Watertown, MA, USA), we formed a case-control group nested within a POAG cohort (n=72,412) formed using International Classification of Disease, Ninth Edition (ICD-9) coding data. Cases (n=1145) had LTP (Current Procedural Terminology code: 65855) with a parts per thousand yen1 year of continuous enrollment both prior to, and following LTP index date in PharMetrics from 1998-2005. Using the date of LTP as the index date, controls (n=2290) without LTP were matched to cases on gender, age, and index year in a 2:1 ratio. Cases and controls had a parts per thousand yen6 months of continuous enrollment in PharMetrics prior to receiving a diagnosis of POAG (ICD-9 code: 365.11). One-year total and ophthalmology healthcare charges were calculated in the year pre- and post-index date (excluding charges for LTP at the index date). Conditional logistic regression models and multiple linear regression models determined the impact of LTP on healthcare charges, while controlling for glaucoma duration and other key covariates. While the mean age of cases (60.1 +/- 13.1 years) and controls (60.3 +/- 13.6 years) was similar (P=0.5589), cases had more comorbid systemic conditions (P < 0.05) and underwent more cataract surgery in the year after index date (4.4% vs. 2.1%; P=0.002). In the year after index date, ophthalmology-related charges increased by $1364 for cases vs. $30 for controls (P=0.0003). Total healthcare charges increased by $5084 for cases and $1594 for controls in the year after index date (P=0.0085). Cases and controls experienced similar increases in ophthalmology-related pharmacy charges from the year pre- to the year post-index date ($26 vs. $43, P=0.385). In both logistic regression and linear regression models, which adjusted for several covariates, performing LTP was associated with increased total healthcare and ophthalmologyrelated charges. Among patients with POAG in this study, performing LTP was associated with increased total and ophthalmologyrelated healthcare charges, while ophthalmology pharmacy charges did not decline.

TI Aged mouse ovaries possess rare premeiotic germ cells that can generate oocytes following transplantation into a young host environment SO AGING-US LA English DT Article DE aging; germ cell; meiosis; Stra8; oogenesis; oocyte; ovary; stem cell ID ADULT MAMMALIAN OVARIES; STEM-CELLS; BONE-MARROW; MICE; EXPRESSION; MEIOSIS; FAILURE; FERTILITY; RENEWAL; PROTEIN AB Of all the major organ systems in the body, the ovaries of females are the first to exhibit impaired function with advancing age. Until recently, traditional thinking was that female mammals are provided with a non-renewable pool of oocyte-containing follicles at birth that are depleted during postnatal life to exhaustion, driving ovarian failure. However, a growing body of evidence, including the isolation of germline stem cells (GSC) from adult mouse ovaries that produce developmentally-competent oocytes, has challenged this belief. In addition, rare germline stem-like cells capable of generating oocytes in vitro that undergo parthenogenesis to form blastocyst-like structures have recently been identified in postmenopausal human ovaries. Here we show that the germline-specific meiosis-commitment genes, Stimulated by retinoic acid gene 8 (Stra8) and Deleted in azoospermia-like ( Dazl), are highly expressed in aged mouse ovaries. However, histological and marker analyses fail to demonstrate the presence of oocytes, supporting that Stra8 and Dazl are expressed in premeiotic germ cells that do not undergo further differentiation. Through the use of aged germline-specific GFP expressing transgenic mice, we further show that these germ cells can generate GFP-positive oocytes that co-express the primordial oocyte marker NOBOX and form follicles when grafted into young adult wild-type female hosts. Thus, aged mouse ovaries possess a rare population of premeiotic germ cells that retain the capacity to form oocytes if exposed to a young host environment.

Drawing from Noelle-Neumann's spiral of silence theory, this study examined the association between communication about HIV/AIDS and prior HIV testing in communities in Tanzania, Zimbabwe, South Africa, and Thailand. Participants (N = 14,818) in 48 communities across five sites throughout the four countries completed a behavioral survey assessing communication, prior voluntary counseling and testing (VCT) uptake, social norms, stigma, and sexual risk. Site-specific logistic regression models demonstrated that frequent conversations about HIV were significantly associated with prior HIV testing at every site. Odds ratios for each site ranged from 1.885 to 3.085, indicating a roughly doubled or tripled chance of past VCT uptake. Results indicate that verbal communication may be an important mechanism for increasing health behaviors and inclusion in future interventions should be considered.

This study provides descriptive information about HIV disclosure among South African mothers and explores whether family context variables interact with maternal HIV disclosure to affect children's functioning. A total of 103 mothers, who self-identified as living with HIV and who were the primary caregivers of a child between the ages of 11 and 16, were interviewed. A total of 44% of mothers had disclosed, and those who had most typically perceived children's reactions to disclosure to be sadness and worry. Widows and married mothers were more likely than single mothers to disclose their HIV status. Disclosure to children significantly predicted externalizing, but not internalizing, behaviors. Family variables had direct but not interactive effects on child functioning. This study highlights the complexity of disclosure-related decisions and the importance of addressing the family context.

This cross-sectional study reports the prevalence of overweight and obesity, and sociodemographic, psychological, and substance use-related risk factors for elevated body mass index (BMI) among 2157 HIV-seropositive (HIV+) in comparison to 730 HIV-seronegative (HIV-) participants in the Women's Interagency HIV Study (WIHS). Separate univariable and multivariate linear regression analyses were completed for HIV+ and HIV- women. Our study revealed a similar proportion of obesity (body mass index [BMI] >= 30) among HIV+ (33%) and HIV+ women (29%) (p = 0.12), as well as comparable median BMI (HIV+: 26.1 versus HIV-: 26.7, p = 0.16). HIV+ compared to HIV- women, respectively, were significantly (p < 0.01) older (median 35.6 versus. 32.5), but similar (p = 0.97) by race/ethnicity (57% African American, 28% Hispanic, and 15% white for both). In multivariate models for both HIV+ and HIV- women, African American race/ethnicity was significantly (p < 0.05) associated with higher BMI, while higher quality of life score and illicit hard drug use were associated with lower BMI. Additionally, smoking, alcohol use, markers of advanced HIV infection (AIDS diagnosis, elevated HIV viral load, low CD4 count), and a history of antiretroviral therapy use (ART) were also associated with lower BMI among HIV+ women. In conclusion, risk factors for elevated BMI were similar for HIV+ and HIV- women in the WIHS. For HIV+ women, all markers of advanced HIV infection and ART use were additionally associated with lower BMI.

TI Clinical trial: the efficacy and safety of routine bowel cleansing agents for elective colonoscopy in persons with spinal cord injury - a randomized prospective single-blind study SO ALIMENTARY PHARMACOLOGY & THERAPEUTICS LA English DT Article ID ORAL SODIUM-PHOSPHATE; COLORECTAL-CANCER; POLYETHYLENE-GLYCOL; RENAL-FUNCTION; CT COLONOGRAPHY; KIDNEY INJURY; FAILURE; NEPHROPATHY; EVACUATION; GUIDELINES AB P>Background As difficulty with evacuation is a common occurrence in individuals with spinal cord injury, preparation prior to colonoscopy may be suboptimal and, perhaps, more hazardous. Aim To assess the safety and efficacy of bowel cleansing regimens in persons with spinal cord injury. Methods Randomized, prospective, single blind study comparing polyethylene glycol (PEG), oral sodium phosphosoda (OSPS) and combination of both for colonic preparation prior to colonoscopy in subjects with spinal cord injury. Results Thirty six subjects with eGFR >= 60 mL/min/1.73 m2 were randomized to PEG or OSPS or PEG+OSPS. Regardless of bowel preparation employed, > 73% of subjects had unacceptable colonic cleansing. No subject in the OSPS preparation group demonstrated a decrease in eGFR or an increase in serum creatinine concentration from the baseline. OSPS and PEG+OSPS preparations caused a transient change in serum potassium, phosphate and calcium concentrations, but no change in electrolytes was noted in the PEG group. Conclusions Neither OSPS alone, PEG alone nor their combination was sufficient to prepare adequately the bowel for colonoscopy in most patients with spinal cord injury. However, administration of OSPS and/or PEG appears to be safe in the spinal cord injury population, provided adequate hydration is provided. C1 [Ancha, H. R.; Spungen, A. M.; Bauman, W.

TI Measuring irritable bowel syndrome patient-reported outcomes with an abdominal pain numeric rating scale SO ALIMENTARY PHARMACOLOGY & THERAPEUTICS LA English DT Article ID QUALITY-OF-LIFE; VISCERAL SENSITIVITY INDEX; CLINICAL IMPORTANCE; ILLNESS SEVERITY; HEALTH-STATUS; IBS; VALIDATION; DISORDERS; VALIDITY; ANXIETY AB P>Background Controversy exists on how to measure patient-reported outcomes in irritable bowel syndrome (IBS) clinical trials effectively. Pain numeric rating scales (NRS) are widely used in the non-IBS pain literature. The Food and Drug Administration has proposed using the NRS in IBS. Aim To test the psychometrics of an abdominal pain NRS in IBS. Methods We analysed data from a longitudinal cohort of Rome III IBS subjects. At entry, subjects completed a 10-point NRS, bowel symptoms, IBS severity measurements (IBS-SSS, FBDSI), health-related quality of life indices (IBS-QOL, EQ5D), and the Worker Productivity Activity Index (WPAI). We repeated assessments at 3 months along with a response scale to calculate the minimal clinically important difference. Results There were 277 subjects (82% women; age = 42 +/- 15) at baseline and 90 at 3 months. The NRS correlated cross-sectionally with IBS-SSS (r = 0.60; P < 0.0011), FBDSI (r = 0.49; P < 0.0001), IBS-QOL (r = 0.43; P < 0.0001), EQ5D (r = 0.48; P < 0.0001), presenteeism (r = 0.39; P < 0.0001), absenteeism (r = 0.17; P = 0.04) and distension (r = 0.46; P < 0.0001), but not stool frequency or form. The minimal clinically important difference was 2.2 points, correlating with a 29.5% reduction over time. Conclusions An abdominal pain NRS exhibits excellent validity and can be readily interpreted with a minimal clinically important difference in patients with IBS. These data support the use of the NRS in IBS clinical trials. C1 [Spiegel, B.; Naliboff, B.; Talley, J.] VA Greater Los Angeles Healthcare Syst, Los Angeles, CA USA.

TI Safety and feasibility of adjunctive antiplatelet therapy with intravenous elinogrel, a direct-acting and reversible P2Y12 ADP-receptor antagonist, before primary percutaneous intervention in patients with ST-elevation myocardial infarction: The Early Rapid ReversAl of Platelet ThromboSis with Intravenous Elinogrel before PCI to Optimize REperfusion in Acute Myocardial Infarction (ERASE MI) pilot trial SO AMERICAN HEART JOURNAL LA English DT Article ID RANDOMIZED CONTROLLED-TRIAL; CORONARY INTERVENTION; SEGMENT ELEVATION; FIBRINOLYTIC THERAPY; TASK-FORCE; CLOPIDOGREL; GUIDELINES; ASPIRIN; TIME AB Background Inhibition of the P2Y12 ADP-receptor with oral antiplatelet agents given to patients undergoing primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) is associated with improved outcomes, but this strategy is limited by the time required for maximal antiplatelet effect after administration. We examined the safety and tolerability of a novel, direct-acting, reversible, intravenous P2Y12 ADP-receptor antagonist, elinogrel, versus placebo when administered to STEMI patients before primary PCI. Methods The ERASE MI trial was a pilot, phase IIA, randomized, double-blind, placebo-controlled, dose-escalation study designed to evaluate the safety and tolerability of escalating doses (10, 20, 40, and 60 mg) of elinogrel administered as a single intravenous bolus before the start of the diagnostic angiogram preceding primary PCI. Patients were randomly assigned in a 1:1 manner to either elinogrel or placebo within each dosing group; and all patients received a 600-mg clopidogrel loading dose, followed by a second 300-mg clopidogrel loading dose 4 hours after PCI. The major outcome, in-hospital bleeding, was assessed with the Thrombolysis in Myocardial Infarction and Global Strategies to Open Occluded Coronary Arteries bleeding scales. Pre-PCI corrected Thrombolysis in Myocardial Infarction frame count and ST-segment resolution were also evaluated. Results Seventy patients were randomized in the dose-escalation study, but the dose-confirmation phase was not started because the trial was prematurely terminated for administrative reasons. The incidence of bleeding events was infrequent and appeared to be similar in patients treated with all doses of elinogrel versus placebo. No differences in serious adverse events, laboratory values, corrected Thrombolysis in Myocardial Infarction frame count, or ST resolution were demonstrated between elinogrel and placebo. Conclusions With the limitations of a small study sample size, this pilot study provided preliminary data on the feasibility and tolerability of escalating doses of a direct-acting, reversible, intravenous P2Y12 ADP-receptor antagonist, elinogrel, as an adjunctive therapy for primary PCI for STEMI.

Methods The impact of ethnicity on the risk factor profiles, use of evidence-based medical therapies, and 2-year cardiovascular outcomes were investigated in 2,168 individuals (blacks n = 237, Hispanics n = 115, whites n = 1,816) from the United States with PAD from the international Reduction of Atherothrombosis for Continued Health Registry. Results Blacks and Hispanics were more likely to have diabetes mellitus and hypertension, whereas whites had a higher rate of diagnosed hypercholesterolemia. Control of blood pressure and cholesterol levels differed significantly in the groups at baseline: elevated blood pressure was present in 55% of blacks versus 48% of Hispanics versus 38% of whites (P < .01), whereas 41% of blacks versus 31% of Hispanics versus 25% of whites had elevated total cholesterol (P < .01). Aspirin use (62% of blacks vs 68% of Hispanics vs 72% of whites, P < .01) and statin use (72% of blacks vs 68% of Hispanics vs 77% of whites, P = .03) also varied significantly. In this context, rates by ethnicity for cardiovascular death, myocardial infarction, or stroke seemed to be no different at 2 years, at 8.8% for the total population: 11.6% for blacks, 8.5% for whites, and 5.0% for Hispanics (P = .32). Fewer blacks (0.6%) had undergone peripheral arterial bypass surgery compared with whites (3.4%) and Hispanics (5.2%) (P = .02). Conclusions Ethnic-related differences have been documented in the prevalence and treatment of several atherosclerotic risk factors known to be associated with PAD, including a variation in the use of surgical revascularization procedures.

TI Relation of Kidney Function and Albuminuria With Atrial Fibrillation (from the Heart and Soul Study) SO AMERICAN JOURNAL OF CARDIOLOGY LA English DT Article ID CYSTATIN-C; RENAL-DISEASE; HEMODIALYSIS; ASSOCIATION; PREVALENCE; SYSTEM AB Atrial fibrillation (AF) is common in end-stage renal disease, but the relation between more modest decrements in kidney function or albuminuria with AF is uncertain. Among 956 outpatients with coronary artery disease, kidney function was assessed using 3 methods (cystatin C-based estimated glomerular filtration rate [eGFR(cys)], creatinine-based eGFR [eGFR(Cr)], and the urinary albumin/creatinine ratio [ACR]) and prevalent AF using surface electrocardiography. Multivariate logistic regression was used to evaluated the association of 2 each measure of kidney function with AF. The mean eGFR(cys) was 71 +/- 23 ml/min/1.73 m(2), and the median ACR was 10 mg/g (interquartile range 6 to 19). Forty subjects (4%) had prevalent AF. Compared to participants with eGFR(cys) in the highest tertile (eGFR(cys) >79), those with eGFRcys in the lowest tertile (eGFR(cys) <62) had more than threefold greater odds of AF (odds ratio [OR] 3.43, 95% confidence interval [CI] 1.18 to 9.97) after multivariate adjustment for traditional cardiovascular disease risk factors. This association remained significant with further adjustment for ACR (OR 3.37, 95% 1.02 to 11.14). Results were similar for eGFR(Cr) but did not reach statistical significance (OR 1.59, 95% CI 0.57 to 4.40). Participants with ACRs in the highest tertile (ACR > 15 mg/g) had more than fourfold greater odds of AF compared to participants in the lowest ACR tertile (ACR <7 mg/g); an association that remained significant after adjustment for eGFR(cys) (OR 4.36, 95% CI 1.45 to 13.05) or eGFRCr (OR 4.61, 95% CI 1.56 to 13.66). In conclusion, among outpatients with coronary artery disease, lower eGFR(cys) and higher ACR were associated with prevalent AF, independent of each other. Published by Elsevier Inc.

TI Mediterranean-style dietary pattern, reduced risk of metabolic syndrome traits, and incidence in the Framingham Offspring Cohort SO AMERICAN JOURNAL OF CLINICAL NUTRITION LA English DT Article ID FOOD FREQUENCY QUESTIONNAIRE; DIABETES-MELLITUS; CARDIOVASCULAR-DISEASE; INSULIN-RESISTANCE; ENERGY-INTAKE; HEALTH; REPRODUCIBILITY; HOMEOSTASIS; PREVALENCE; MANAGEMENT AB Background: The benefit of the Mediterranean-style dietary pattern in mitigating metabolic risk factors for type 2 diabetes and cardiovascular disease has not been well investigated among nondiabetic Americans. Objective: The aim of this study was to examine the prospective association between the Mediterranean-style dietary pattern and metabolic syndrome. Design: The Mediterranean-style dietary pattern score (MSDPS) was used to characterize a Mediterranean-style dietary pattern in the Framingham Heart Study Offspring Cohort. We examined the longitudinal association between MSDPS and metabolic syndrome traits (including homeostasis model assessment-insulin resistance, fasting glucose, waist circumference, triglyceride, HDL cholesterol, and systolic and diastolic blood pressure) among 2730 participants of the Framingham Heart Study Offspring Cohort without type 2 diabetes (baseline median age: 54 y; 55% women), who were followed from the fifth (baseline) to the seventh study examinations (mean follow-up time: 7 y), and metabolic syndrome incidence (according to the National Cholesterol Education Program Adult Treatment Panel III definition) in 1918 participants free of the condition at baseline. Results: A higher MSDPS was associated with lower homeostasis model assessment-insulin resistance (P = 0.02), waist circumference (P < 0.001), fasting plasma glucose (P = 0.03), and triglycerides (P < 0.001) and higher HDL cholesterol (P = 0.02) after adjustment for the corresponding baseline values and for several confounding factors associated with type 2 diabetes risk. Participants in the highest quintile category of the MSDPS had a lower incidence of metabolic syndrome than those in the lowest quintile category (38.5% compared with 30.1%; P = 0.01). Conclusion: Our study suggests that the consumption of a diet consistent with the principles of the Mediterranean-style diet may protect against metabolic syndrome in Americans.

Giovannucci, Edward TI A randomized trial on folic acid supplementation and risk of recurrent colorectal adenoma SO AMERICAN JOURNAL OF CLINICAL NUTRITION LA English DT Article ID FOLATE; PREVENTION; CANCER; SAFETY AB Background: Evidence from observational studies suggests that inadequate folate status enhances colorectal carcinogenesis, but results from some randomized trials do not support this hypothesis. Objective: To assess the effect of folic acid supplementation on recurrent colorectal adenoma, we conducted a cost-efficient, double-blind, randomized trial among participants of 2 large prospective cohorts, the Health Professionals Follow-Up Study and the Nurses' Health Study. Design: Participants were randomly assigned to receive folic acid (1 mg/d) (n = 338) or placebo (n = 334) for 3-6.5 y. The primary endpoint was any new diagnosis of adenoma during the study period (May 1996-March 2004). Secondary outcomes were adenoma by site and stage and number of recurrent adenomas. Associations were also examined by plasma folate concentrations at baseline. Results: Incidence of at least one recurrent adenoma was not significantly associated with folic acid supplementation [relative risk (RR): 0.82; 95% CI: 0.59,1.13; P = 0.22]. Among participants with low plasma folate concentrations at baseline (<= 7.5 ng/mL), those randomly assigned to receive folic acid experienced a significant decrease in adenoma recurrence (RR: 0.61; 95% CI: 0.42, 0.90; P = 0.01), whereas for subjects with high folate concentrations at baseline (>7.5 ng/mL), supplemental folic acid had no significant effect (RR: 1.28; 95% CI: 0.82, 1.99; P = 0.27, P(interaction) = 0.01). Contrary to findings from another clinical trial, there was no evidence for an increased risk of advanced or multiple adenomas. Conclusions: Our results do not support an overall protective effect of folic acid supplementation on adenoma recurrence. Folic acid supplementation may be beneficial among those with lower folate concentrations at baseline. This trial was registered at clinical trials. gov as NCT00512850.

Methods: Three types of fiber posts (DT Light Post, GC Post, FRC Postect Plus) were divided in different groups (n=12) according to the storage condition (dry at 37 degrees C; saline water at 37 degrees C; mineral oil at 37 degrees C and storage inside the roots of extracted human teeth immersed in saline water at 37 degrees C and duration (6, 12 months). A universal testing machine loading at a 90 degrees angle was employed for the three-point bending test. The test was carried out until fracture of the post. A 3-way ANOVA and Tukey's test (alpha= 0.05) were used to compare the effect of the experimental factors on the fracture strength. Two posts of each group were observed before and after the storage using a scanning electron microscope. Results: Storage condition and post type had a significant effect on post fracture strength (P< 0.05). The interaction between these factors was significant (P< 0.05). Water storage significantly decreased the fracture strength, regardless of the post type and the storage duration. Storage inside roots, in oil, and at dry conditions did not significantly affect post fracture strength. SEM micrographs revealed voids between fibers and resin matrix for posts stored in water. Posts stored under the other conditions showed a compact matrix without porosities. (Am J Dent 2009;22:366-370).

The authors conducted a Human Genome Epidemiology review and meta-analysis of published case-control studies of the UCHL1 S18Y variant and Parkinson's disease in Asian and Caucasian samples. The meta-analysis of studies in populations of Asian ancestry showed a statistically significant association between the Y allele and reduced risk of Parkinson's disease under a recessive model (odds ratio (OR) for YY vs. SY + SS = 0.79, 95% confidence interval (CI): 0.67, 0.94; P = 0.006). For a dominant model, the association was not significant in Asian populations (OR for YY + SY vs. SS = 0.88, 95% CI: 0.68, 1.14; P = 0.33). For populations of European ancestry, the meta-analysis showed a significant association between the Y allele and decreased risk of Parkinson's disease under a dominant model (OR = 0.89, 95% CI: 0.81, 0.98; P = 0.02) but not under a recessive model (OR = 0.92, 95% CI: 0.66, 1.30; P = 0.65). Using the Venice criteria, developed by the Human Genome Epidemiology Network Working Group on the assessment of cumulative evidence, the authors concluded that moderate evidence exists for an association between the S18Y variant and Parkinson's disease.

Design: Multisite randomized clinical trial. Setting: Eighteen primary care clinics from eight healthcare organizations. Participants: Nine hundred six patients (N = 606 young-old; N = 300 old-old) with major depression and/or dysthymia who were randomized to receive collaborative care in the Improving Mood: Promoting Access to Collaborative Treatment trial. Intervention: Patients had access for 12 months to a depression clinical specialist who coordinated depression care with their primary care physician. Measurements: Young-old and old-old patients were compared on process of care and outcome variables. Process of care was determined by the type of treatment and level of care received. Clinical outcomes included Symptom Checklist (SCL)-20 depression scores, treatment response (defined as a >= 50% decrease in the SCL-20 score from baseline), and complete remission (defined as a SCL-20 score <0.5) at 3-, 6-, 12-, 18-, and 24-month follow-up. Results: The process of care variables did not significantly differ between the two age groups. Young-old patients had similar treatment responses at initial follow-up (3 months) but were significantly more likely to respond to treatment and meet complete remission criteria than old-old patients at 6-, 12-, 18-, and 24-months. Conclusions: Young-old and old-old patients who receive collaborative depression care have a similar initial clinical response, but old-old patients may have a lower rate of long-term treatment response and complete remission in the long run.

Obesity assessed in midlife has been associated with chronic kidney disease. Study Design: Cohort study. Setting & Participants: 4,295 participants in the community-based Cardiovascular Health Study, aged >= 65 years. Predictors: Body mass index, waist circumference, and fat mass measured using bioelectrical impedance. Outcome: Change in glomerular filtration rate (GFR) during 7 years of follow-up. Measurements: Longitudinal estimates of GFR calculated using the 4-variable Modification of Diet in Renal Disease (MDRD) Study equation. Results: Estimated GFR decreased by an average of 0.4 +/- 3.6 mL/min/1.73 m(2)/y, and rapid GFR loss (>3 mL/min/1.73 m(2)/y) occurred in 693 participants (16% ). Baseline body mass index, waist circumference, and fat mass were each associated with increased risk of rapid GFR loss: ORs, 1.19 (95% Cl, 1.09-1.30) per5 kg/m(2),1.25 (95% Cl, 1.16-1.36) per 12 cm, and 1.14 (95%CI, 1.05-1.24) per 10 kg after adjustment for age, sex, race, and smoking. The magnitude of increased risk was larger for participants with estimated GFR < 60 mL/min/1.73 m(2) at baseline (P for interaction < 0.05). Associations were substantially attenuated by further adjustment for diabetes, hypertension, and C-reactive protein level. Obesity measurements were not associated with change in GFR estimated using serum cystatin C level. Limitations: Few participants with advanced chronic kidney disease at baseline, no direct GFR measurements. Conclusion: Obesity may be a modifiable risk factor for the development and progression of kidney disease in older adults. Am J Kidney Dis 54:1043-1051.

Study Design and Methods: We measured antibiotic utilization rates among 229 US commercial health plans that participated in the 2005 Healthcare Effectiveness Data and Information Set. Rates were adjusted to account for health plan age and sex distribution. To estimate antibiotic costs, we multiplied utilization data for each drug class by national estimates of intraclass distribution of drugs, duration of therapy, and median average wholesale price. Results: Antibiotic utilization rates varied markedly among plans, ranging from 0.64 antibiotic fills per member per year (PMPY) at the 5th percentile of plans to 1.08 fills PMPY at the 95th percentile, with a mean of 0.88 (SD +/- 0.15) antibiotic fills PMPY. US census region was the strongest predictor of antibiotic utilization. Antibiotic costs averaged $49 PMPY and ranged from $34 to $63 PMPY among plans at the 5th and 95th percentiles of cost, respectively. If a health plan with 250,000 members at the 90th percentile of antibiotic costs reduced its costs to the 25th percentile, annual drug cost savings would be approximately $4.1 million. Conclusions: Antibiotic utilization varies substantially among commercial health plans and is not accounted for by differences in the age and sex distribution of plan members. Because reducing rates of antibiotic utilization is likely to lower costs and improve quality, high-utilizing plans may reap considerable rewards from investing in programs to reduce the overuse of antibiotics.

We investigated the independent and joint associations between vigorous activity and BMI on diabetes risk in men. METHODS: This was a prospective cohort design within the Physicians' Health Study, using Cox proportional hazards models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) of incident diabetes in 20,757 men without diabetes at baseline. Models were based on self-reported BMI and exercise frequency at baseline, first separately and then with a 6-category joint variable combining World Health Organization BMI category (normal/overweight/obese) with activity status (active/inactive) using weekly vigorous activity as the threshold. RESULTS: After a median follow-up of 23.1 years, there were 1836 cases of incident diabetes. Compared with active participants with normal BMIs, active but overweight and obese men had multivariable-adjusted HRs of 2.39 (95% CI, 2.11-2.71) and 6.22 (95% CI, 5.12-7.56). Inactive men with normal, overweight, or obese BMIs had multivariable-adjusted HRs of 1.41 (95% CI, 1.19-1.67), 3.14 (95% CI, 2.73-3.62), and 6.57 (95% CI, 5.25-8.21). CONCLUSION: Active men with normal and overweight BMIs had lower diabetes hazards than their inactive counterparts, but no difference by weekly activity was seen in obese men. Elevated BMI is a key driver of diabetes risk, with relatively modest attenuation by activity. Published by Elsevier Inc.

TI A Computer-Tailored Intervention to Promote Informed Decision Making for Prostate Cancer Screening Among African American Men SO AMERICAN JOURNAL OF MENS HEALTH LA English DT Article DE health screening; digital rectal exam; PSA testing; prostate cancer; oncology/cancer ID RANDOMIZED CONTROLLED-TRIAL; RACIAL-DIFFERENCES; EDUCATIONAL INTERVENTIONS; ENTERTAINMENT EDUCATION; HEALTH DISPARITIES; LITERATE WOMEN; ANTIGEN TEST; KNOWLEDGE; AID; INFORMATION AB African American men experience a disproportionate burden of prostate cancer (CaP) morbidity and mortality. National screening guidelines advise men to make individualized screening decisions through a process termed informed decision making (IDM). In this pilot study, a computer-tailored decision-aid designed to promote IDM was evaluated using a pre-/posttest design. African American men aged 40 years and older were recruited from a variety of community settings (n = 108). At pretest, 43% of men reported having made a screening decision; at posttest 47% reported this to be the case (p = .39). Significant improvements were observed between pre- and posttest on scores of knowledge, decision self-efficacy, and decisional conflict. Men were also more likely to want an active role in decision making after using the tool. These results suggest that use of a computer-tailored decision aid is a promising strategy to promote IDM for CaP screening among African American men.

This is a biologically plausible mechanism whereby beta 2 adrenergic agonists can induce functional and behavioral teratogenesis, which explains their association with increases in autism spectrum disorders, psychiatric disorders, poor cognitive, motor function and school performance, and changes in blood pressure in the offspring. The use of beta 2 adrenergic agonists should be limited to proven indications when alternate drugs are ineffective or unavailable; the risks of untreated disease to the mother and fetus are greater than the risk of the beta 2 adrenergic agonist.

TI Comprehensive Analysis of Complement Factor H and LOC387715/ARMS2/HTRA1 Variants With Respect to Phenotype in Advanced Age-Related Macular Degeneration SO AMERICAN JOURNAL OF OPHTHALMOLOGY LA English DT Article ID CHOROIDAL NEOVASCULARIZATION; LOC387715 GENOTYPES; STRONG ASSOCIATION; Y402H VARIANT; POLYMORPHISM; RISK; HTRA1; CFH; POPULATION; EYE AB PURPOSE: To examine the interaction of genotypic variation of 16 single-nucleotide polymorphisms (SNP) in the complement factor H (CFH) and LOC387715/ARMS2/HTRA1 loci with clinical characteristics of age-related macular degeneration (AMD). DESIGN: Retrospective cohort study. METHODS: Eighty,four patients with neovascular AMD were genotyped using direct sequencing or Sequenom iPLEX technology. The Fisher exact test, Cochran-Mantel-Haenszel statistics, and Mann-Whitney U test were used to assess the effect of each SNP with respect to the following phenotypic manifestations: age at diagnosis, gender, affected eye, study and fellow eye visual acuity at diagnosis and at last follow-up, study eye best acuity during follow-up, presence of large drusen and retinal pigment epithelium (RPE) hyperpigmentation in study and fellow eye, choroidal neovascularization (CNV) angiographic subtype (classic vs occult), CNV size, presence of wet AMD in fellow eye, presence of dry AMD in fellow eye, and smoking history. RESULTS: Only SNPs in the LOC387715/ARMS2/HTRA1 (10q26) region were associated with disease phenotypes. The polymorphisms rs10664316 and rs1049331 were associated with a decreased risk of poor visual acuity during follow-up and at diagnosis; rs2672598 and rs2293870 were associated with a decreased risk of RPE hyperpigmentation; rs10664316 was associated with a de, creased risk of RPE hyperpigmentation with large drusen in the study eye, but an increased risk of large drusen in the fellow eye; rs11200638 was associated with an increased risk of larger CNV; rs10490924 and rs11200638 were associated with younger age of diagnosis. CONCLUSIONS: Several polymorphisms examined in the LOC387715/ARMS2/HTRA1 locus, but none in the CFH region, correlated with specific phenotypic attributes of AMD. (Am J Ophthalmol 2009; 148: 869-874.

ANP blocks vascular endothelial growth factor (VEGF) production and signaling in vitro; however, its role in vascular leakage and angiogenesis is unknown. In vitro, retinal barrier permeability (transepithelial electrical resistance (TEER)) was measured in cultured retinal endothelial (HuREC) and retinal epithelial (ARPE-19) cells with VEGF (10 ng/ml), ANP (1 pM to I mu mol/L), and/or isatin, an ANP receptor antagonist. In vivo, blood-retinal barrier (BRB) leakage was studied using the Evans Blue dye technique in rats treated with intravitreal injections of ANP, VEGF, or vehicle. Choroidal neovascularization was generated by laser injury, and 7 days later, lesion size and leakage was quantitated. ANP significantly reversed VEGF-induced BRB TEER reduction in both HuREC and ARPE-19 cells, modeling the inner and the outer BRB, respectively. Isatin, a specific ANP receptor antagonist, reversed ANP's effect. ANP reduced the response of ARPE-19 cells to VEGF apically but not basolaterally, suggesting polarized expression of the ANP receptors in these cells. ANP's TEER response was concentration but not time dependent. lit vivo, ANP significantly reduced VFGF-induced BRB leakage and the size of laser-induced choroidal neovascularization lesions. In sum, ANP is an effective inhibitor of VEGF-induced vascular leakage and angiogenesis in vivo. These results may lead to new treatments for ocular diseases where VEGF plays a central role, such as age-related macular degeneration or diabetic retinopathy.

Design: In this multicenter, interdisciplinary study, a convenience sample of 61 participants with spina bifida from regional spina bifida clinics (mean age = 21.0 +/- 2.1 yrs) participated in a structured clinical interview on self-management and completed standardized self-report measures of psychological distress, quality of life, and mobility status. Participants were divided into three mobility groups: ambulators, part-time wheelchair users, and full-time wheelchair users and were compared with respect to outcome measures. Results: We found that full-time wheelchair use is associated with reduced quality of life but that psychological distress and problems with self-management are prevalent, regardless of mobility status. Conclusion: Research should be aimed at assessing life satisfaction as it relates to assistive technology use to delineate further how technological advancements in wheelchair design and universal design of homes and communities can have the greatest impact on mobility and quality of life.

Design: Multicenter cross-sectional study. One hundred twenty-six manual wheelchair-using individuals with chronic paraplegia answered self-administered questionnaires on demographics, symptoms, and functional status. They underwent physical examination specific for carpal tunnel syndrome and upper-limb nerve conduction studies. Results: Fifty-seven percent of subjects had symptoms (72.2% bilateral); hand numbness was most common. Sixty percent of subjects had carpal tunnel syndrome physical examination findings (59.2% bilateral). Those with physical examination findings were more likely to have longer duration of injury (P = 0.003). Seventy-eight percent of subjects had electrophysiologic evidence of median mononeuropathy. Symptomatic subjects had significantly greater median-ulnar motor latency difference in the dominant hand (P = 0.02) and smaller compound muscle action potential amplitudes bilaterally (dominant hand, P = 0.01; nondominant hand, P = 0.04). Persons with carpal tunnel syndrome symptoms and physical examination findings had significantly worse functional status (symptoms, P < 0.001; physical examination, P = 0.02) and symptom severity scores (symptoms, P < 0.001; physical examination, P = 0.01), but a similar difference between subjects with and without median mononeuropathy was not seen. Logistic regression analysis revealed that the presence of symptoms was predicted by median-ulnar motor latency difference in the dominant hand (odds ratio, 4.38; 95% confidence interval 1.72-11.14) and sensory nerve action potential amplitude in the nondominant hand (odds ratio, 0.97; 95% confidence interval, 0.94-0.99). Conclusions: The interaction among symptoms, physical examination, and nerve conduction study findings is complex. Carpal tunnel syndrome and median mononeuropathy are highly prevalent and functionally significant. This study highlights the need for primary prevention and patient education for preserving upper-limb function.

Heightened colon motor activity measured by a wireless capsule in patients with constipation: relation to colon transit and IBS. Am J Physiol Gastrointest Liver Physiol 297: G1107-G1114, 2009. First published October 1, 2009; doi: 10.1152/ajpgi.00136.2009.-Relationships of regional colonic motility to transit in health, constipation, and constipation-predominant irritable bowel syndrome (C-IBS) are poorly characterized. This study aimed to 1) characterize regional differences in colon pressure, 2) relate motor differences in constipation to colon transit, and 3) quantify the role of IBS in altered contractility with constipation. Colon pH and pressure were measured by wireless capsules in 53 healthy and 36 constipated subjects. Numbers of contractions > 25 mmHg and areas under curves (AUC) were calculated for colon transit quartiles by time. Constipation was classified as normal transit (< 59 h), moderate slow transit (STC) (59-100 h), and severe STC (> 100 h). Twelve out of 36 constipated subjects had C-IBS; 24 had functional constipation. Numbers of contractions and AUCs increased from the first to the fourth quartile in health (P < 0.0001). Mean numbers of contractions in constipated subjects were similar to controls. Mean AUCs with normal transit (P = 0.01) and moderate STC (P = 0.004) but not severe STC (P = NS) were higher than healthy subjects. IBS was associated with greater mean numbers of contractions (P = 0.05) and AUCs (P = 0.0006) vs. controls independent of transit. Numbers of contractions increased from the first to fourth quartiles in moderate STC, C-IBS, and functional constipation; AUCs increased from the first to fourth quartiles in all groups (all P < 0.05). In conclusion, colon pressure activity is greater distally than proximally in health. Constipated patients with normal or moderately delayed transit show increased motor activity that is partly explained by IBS. These findings emphasize differential effects on transit and motility in different constipation subtypes.

Neuregulin-1 attenuated doxorubicin-induced decrease in cardiac troponins. Am J Physiol Heart Circ Physiol 297: H1974-H1983, 2009. First published October 2, 2009; doi: 10.1152/ajpheart.01010.2008. Neuregulin-1 (NRG1) is a potential therapeutic agent for the treatment of doxorubicin (Dox)-induced heart failure. NRG1, however, activates the erbB2 receptor, which is frequently overexpressed in breast cancers. It is, therefore, important to understand how NRG1, via erbB2, protects the heart against Dox cardiotoxicity. Here, we studied NRG1-erbB2 signaling in Dox-treated mice hearts and in isolated neonatal rat ventricular myocytes (NRVM). Male C57BL/6 mice were treated with recombinant NRG1 before and daily after a single dose of Dox. Cardiac function was determined by catheterization. Two-week survival was analyzed by the Kaplan-Meier method. Cardiac troponins [cardiac troponin I (cTnI) and cardiac troponin T (cTnT)] and phosphorylated Akt protein levels were determined in mice hearts and in NRVM by Western blot analysis. Activation of caspases and ubiquitinylation of troponins were determined in NRVM by caspase assay and immunoprecipitation. NRG1 significantly improved survival and cardiac function in Dox-treated mice. NRG1 reduced the decrease in cTnI, cTnT, and cardiac troponin C (cTnC) and maintained Akt phosphorylation in Dox-treated mice hearts. NRG1 reduced the decrease in cTnI and cTnT mRNA and proteins in Dox-treated NRVM. Inhibition of erbB2, phosphoinositide 3-kinase (PI3K), Akt, and mTOR blocked the protective effects of NRG1 on cTnI and cTnT in NRVM. NRG1 significantly reduced Dox-induced caspase activation, which degraded troponins, in NRVM. NRG1 reduced Dox-induced proteasome degradation of cTnI. NRG1 attenuates Dox-induced decrease in cardiac troponins by increasing transcription and translation and by inhibiting caspase activation and proteasome degradation of troponin proteins. NRG1 maintains cardiac troponins by the erbB2-PI3K pathway, which may lessen Dox-induced cardiac dysfunction.

First published October 14, 2009; doi:10.1152/ajpregu.00445.2009.-Hemorrhagic shock (HS) due to major trauma predisposes the host to the development of acute lung inflammation and injury. The lung vascular endothelium is an active organ that plays a central role in the development of acute lung injury through generating reactive oxygen species and synthesizing and releasing of a number of inflammatory mediators, including leukocyte adhesion molecules that regulate neutrophils emigration. Previous study from our laboratory has demonstrated that in a setting of sepsis, Toll-like receptor-4 (TLR4) signaling can induce TLR2 expression in endothelial cells (ECs), thereby increasing the cells' response to TLR2 ligands. The present study tested the hypothesis that TLR4 activation by HS and the resultant increased TLR2 surface expression in ECs might contribute to the mechanism underlying HS-augmented activation of lung ECs. The results show that high-mobility group box 1 (HMGB1) through TLR4 signaling mediates HS-induced surface expression of TLR2 in the lung and mouse lung vascular endothelial cells (MLVECs). Furthermore, the results demonstrate that HMGB1 induces activation of NAD(P)H oxidase and expression of ICAM-1 in the lung, and MLVECs sequentially depend on TLR4 in the early phase and on TLR2 in the late phase following HS. Finally, the data indicate an important role of the increased TLR2 surface expression in enhancing the activation of MLVECs and augmenting pulmonary neutrophil infiltration in response to TLR2 agonist peptidoglycan. Thus, induction of TLR2 surface expression in lung ECs, induced by HS and mediated by HMGB1/TLR4 signaling, is an important mechanism responsible for endothelial cell-mediated inflammation and organ injury following trauma and hemorrhage.

First published September 23, 2009; doi:10.1152/ajprenal.90762.2008.-Aquaporin 1 (AQP1) is the major water channel in the renal proximal tubule (PT) and thin descending limb of Henle, but its regulation remains elusive. Here, we investigated the effect of ANG II, a key mediator of body water homeostasis, on AQP1 expression in immortalized rat proximal tubule cells (IRPTC) and rat kidney. Real-time PCR on IRPTC exposed to ANG II for 12 h revealed a biphasic effect AQP1 mRNA increased dose dependently in response to 10(-12) to 10(-8) M ANG II but decreased by 50% with 10(-7) M ANG II. The twofold increase of AQP1 mRNA in the presence of 10(-8) M ANG II was abolished by the AT(1) receptor blocker losartan. Hypertonicity due to either NaCl or mannitol also upregulated AQP1 mRNA by three- and twofold, respectively. Immunocytochemistry and Western blotting revealed a two- to threefold increase in AQP1 protein expression in IRPTC exposed concomitantly to ANG II (10(-8)M) and hypertonic medium (either NaCl or mannitol), indicating that these stimuli were not additive. Three-dimensional reconstruction of confocal images suggested that AQP1 expression was increased by ANG II in both the apical and basolateral poles of IRPTC. In vivo studies showed that short-term ANG II infusion had a diuretic effect, while this effect was attenuated after several days of ANG II infusion. After 10 days, we observed a twofold increase in AQP1 expression in the PT and thin descending limb of Henle of ANG II-infused rats that was abolished when rats were treated with the selective AT(1)-receptor antagonist olmesartan. Thus ANG II increases AQP1 expression in vitro and in vivo via direct interaction with the AT(1) receptor, providing an important regulatory mechanism to link PT water reabsorption to body fluid homeostasis via the renin-angiotensin system.

TI Improving Latino Disaster Preparedness Using Social Networks SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID PUBLIC-HEALTH EMERGENCIES; HIDDEN POPULATIONS; RISK; INFORMATION AB Background: Culturally targeted, informal social networking approaches to improving disaster preparedness have not been empirically tested. Purpose: In partnership with community health promoters and the Los Angeles County Department of Public Health, this study tested a disaster preparedness program for Latino households. Design: This study had a community-based, randomized, longitudinal cohort design with two groups and was conducted during February-October 2007. Assessments were made at baseline and 3 months. Analyses were carried out January-October 2008. Settings/participants: Community-based study of 231 Latinos living in Los Angeles County. Intervention: Participants were randomly assigned to attending platicas (small-group discussions led by a health promoter/promotora de salud) or receiving "media" (a culturally tailored mailer). A total of 187 (81.0%) completed the 3-month follow-up. Main outcome measure: A self-reported disaster preparedness checklist was used. Results: Among participants who did not have emergency water pre-intervention, 93.3% of those in the platica arm had it at follow-up, compared to 66.7% in the media arm (p=0.003). Among participants who did not have food pre-intervention, 91.7% in the platica arm reported it at follow-up, compared to 60.6% in the media arm (p=0.013). Finally, among participants who did not have a family communication plan pre-intervention, 70.4% in the platica arm reported one at follow-up, compared to 42.3% in the media arm (p=0.002). Conclusions: Although both arms improved in stockpiling water and food and creating a communication plan, the platica arm showed greater improvement than the media group.

TI Racial and Ethnic Disparities in Awareness of Genetic Testing for Cancer Risk SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID HEALTH INTERVIEW SURVEY; ACCULTURATION; BREAST; RACE AB Background: Racial and ethnic disparities in awareness of genetic testing for cancer risk are substantial. Purpose: This study assesses the relative importance of contributing factors to gaps in awareness of genetic testing for cancer risk across racial and ethnic groups. Methods: Data from the 2005 National Health Interview Survey (N=25,364) were analyzed in 2009 to evaluate the contribution of demographic factors, SES, health Status, nativity/length of residency in the U.S., personal/family history of cancer, and perceived cancer risk to racial and ethnic disparities in genetic testing awareness for cancer risk. The contribution of each factor was assessed using the Fairlie decomposition technique. Results: About 48% of non-Hispanic whites reported that they had heard about genetic testing, followed by 31% of blacks, 28% of Asians, and 19% of Hispanics. Education and nativity/length of residency in the U.S. explained 26% and 30% of the gap between whites and Hispanics, respectively. Education accounted for 22% of the white-black gap, with residential region explaining another 11%. Nativity/length of residency in the U.S. explained 51% of the white-Asian gap. Conclusions: The relative importance of Factors contributing to racial and ethnic disparities in genetic testing awareness is specific to the particular groups under comparison. Diverse, culturally competent approaches are needed to improve awareness for different racial and ethnic groups.

Methods: Baseline data were collected during 2004-2005 among a predominately black and Hispanic sample of adult residents living in 12 low-income-housing sites in Boston MA (n=1055). Residents reported experiences of lifetime racial discrimination during interviewer-administered surveys and wore a pedometer for 5 days to measure physical activity. For analyses, performed in 2009, linear regression models with a cluster design were conducted to predict physical activity, measured as steps per day. Results: Nearly 48% of participants reported ever experiencing racial discrimination, and discrimination was most commonly experienced on the street or in a public setting. No association was found between discrimination and physical activity, when examined in bivariate, multivariable, or race-stratified models. Conclusions: The current results indicate that self-reported racial discrimination is not a key determinant of physical activity among residents living in low-income housing. However, additional research is warranted to address current limitations of this, study.

TI A Low-Literacy Medication Education Tool for Safety-Net Hospital Patients SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article; Proceedings Paper CT Annual Meeting of the Robert Wood Johnson Clinical Scholars CY APR 11, 2008 CL Washington, DC ID CONGESTIVE-HEART-FAILURE; HEALTH LITERACY; ELDERLY PATIENTS; ADHERENCE; KNOWLEDGE; INTERVENTION; PREVENTION; DISCHARGE; REGIMENS; OUTCOMES AB Background: To improve medication adherence in cardiac patients, in partnership with a safety-net provider, this research team developed and evaluated a low-literacy medication education tool. Methods: Using principles of community-based participatory research, the team developed a prototype of a low-literacy hospital discharge medication education tool, customizable for each patient, featuring instruction-specific icons and Pictures of pills. In 2007, a randomized controlled clinical trial was performed, testing the tool's effect on posthospitalization self-reported medication adherence and knowledge, 2 weeks postdischarge in English- and Spanish-speaking safety-net inpatients. To validate the self-report measure, 4 weeks postdischarge, investigators collected self-reports of the number of pills remaining for each medication in a subsample of participants. Nurses rated tool acceptability. Results: Among the 166/210 eligible participants (79%) completing the Week-2 interview, self-reported medication adherence was 70% (95% CI=62%, 79%) in intervention participants and 78% (95% CI=72%, 84%) in controls (p=0.13). Among the 85 participants (31%) completing the Week-4 interview, self-reported pill Counts indicated high adherence (greater than 90%) and did not differ between Study arms. Self-reported adherence was correlated with self-reported pill count in intervention participants (R=0.5, p=0.004) but not in controls (R=0.07, p=0.65). There were no differences by study arm in medication knowledge. The nurses rated the tool as highly acceptable. Conclusions: Although the evaluation did not demonstrate the tool to have any effect on self-reported medication adherence, patients who received the schedule self-reported their medication adherence more accurately, perhaps indicating C1 [Cordasco, Kristina M.; Asch, Steven M.] VA Greater Los Angeles Healthcare Syst, Los Angeles, CA 90073 USA.

TI Economic Evaluation of a Comprehensive Teenage Pregnancy Prevention Program Pilot Program SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID SAFER CHOICES; UNITED-STATES; MATERNAL AGE; OUTCOMES; SCHOOL; ADOLESCENTS; HIV; STD AB Background: Previous research has Suggested that comprehensive teenage pregnancy prevention programs that address sexual education and life skills development and provide academic Support are effective in reducing births among enrolled teenagers. However, there have been limited data on the costs and cost effectiveness Of Such programs. Purpose: The study used a community-based participation, research approach to develop estimates of the cost-benefit of the Pathways/Senderos Center, a comprehensive neighborhood-based program to prevent unintended pregnancies and promote positive development for adolescents. Methods: Using data from 1997-2003, an in-time intervention analysis was conducted to determine program cost-benefit while teenagers were enrolled; an extrapolation analysis was then used to estimate accrued economic benefits and cost-benefit up to age 30 years. Results: The program operating costs totaled $3,228,152.59 and reduced the teenage childbearing rate from 94.10 to 40.00 per 1000 teenage girls, averting $52,297.84 in total societal costs, with an economic benefit to society from program participation of $2,673,153.11. Therefore, total costs to society exceeded economic benefits by $559,677.05, or $1599.08 per adolescent per year. In an extrapolation analysis, benefits to society exceed costs by $10,474.77 per adolescent per year by age 30 years on average, with social benefits outweighing total social costs by age 20.1 years. Conclusions: This comprehensive teenage pregnancy prevention program is estimated to provide societal economic benefits once participants are young adults, suggesting the need to expand beyond pilot demonstrations and evaluate the long-range cost effectiveness of similarly comprehensive programs when they are implemented more widely in high-risk neighborhoods.

TI Impaired Vascular Regulation in Patients with Obstructive Sleep Apnea SO AMERICAN JOURNAL OF RESPIRATORY AND CRITICAL CARE MEDICINE LA English DT Article DE hypoxia; sleep; vasodilation; cerebral vascular circulation; regional blood flow ID POSITIVE AIRWAY PRESSURE; ENDOTHELIAL FUNCTION; CEREBROVASCULAR RESPONSES; CHEMOREFLEX SENSITIVITY; SELECTIVE POTENTIATION; VASODILATOR RESPONSES; VENTILATORY RESPONSE; CEREBRAL-ARTERIES; HYPOXIC DILATION; BLOOD-PRESSURE AB Rationale Impaired endothelium-dependent vasodilation has been documented in patients with sleep apnea. This impairment may result in blood flow dysregulation during apnea-induced fluctuations in arterial blood gases. Objectives: To test the hypothesis that hypoxic and hypercapnic vasodilation in the forearm and cerebral circulation are impaired in patients with sleep apnea. Methods: We exposed 20 patients with moderate to severe sleep apnea and 20 control subjects, to isocapnic hypoxia and hyperoxic hypercapnia. A subset of 14 patients was restudied after treatment with continuous positive airway pressure. Measurements and Main Results: Cerebral flow velocity (transcranial Doppler), forearm blood flow (venous occlusion plethysmography), arterial pressure (automated sphygmomanometry), oxygen saturation (pulse oximetry), ventilation (pneumotachograph), and endtidal oxygen and carbon dioxide tensions (expired gas analysis) were measured during three levels of hypoxia and two levels of hypercapnia. Cerebral vasodilator responses to hypoxia (-0.65 +/- 0.44 vs. -1.02 +/- 0.72 [mean +/- SD] units/% saturation; P = 0.03) and bypercapnia (2.01 +/- 0.88 vs. 2.57 +/- 0.89 units/mm Hg; P = 0.03) were smaller in patients versus control subjects. Hypoxic vasodilation in the forearm was also attenuated (-0.05 +/- 0.09 vs. -0.10 +/- 0.09 unit/% saturation; P = 0.04). Hypercapnia did not elicit forearm vasodilation in either group. Twelve weeks of continuous positive airway pressure treatment enhanced hypoxic vasodilation in the cerebral circulation (-0.83 +/- 0.32 vs. -0.46 +/- 0.29 units/% saturation; P = 0.01) and forearm (-0.19 +/- 0.15 vs. -0.02 +/- 0.08 units/% saturation; P = 0.003), and hypercapnic vasodilation in the brain showed a trend toward improvement (2.24 +/- 0.78 vs. 1.76 +/- 0.64 units/mm Hg; P 0.06). Conclusions: Vasodilator responses to chemical stimuli in the cerebral circulation and the forearm are impaired in many patients with obstructive sleep apnea. Some of these impairments can be improved with continuous positive airway pressure.

TI Genetic Polymorphisms of Peptidase Inhibitor 3 (Elafin) Are Associated with Acute Respiratory Distress Syndrome SO AMERICAN JOURNAL OF RESPIRATORY CELL AND MOLECULAR BIOLOGY LA English DT Article DE acute respiratory distress syndrome; elafin; genetic susceptibility; haplotypes; tagging SNP ID ELASTASE-SPECIFIC INHIBITOR; ACUTE LUNG INJURY; PROTEINASE-INHIBITOR; NEUTROPHIL ELASTASE; EPITHELIAL-CELLS; HUMAN KERATINOCYTES; EXPRESSION; ARDS; SEQUENCE; SLPI AB Peptidase inhibitor 3 (PI3, elafin) is a protease inhibitor produced locally in the lung, where it plays a central role in controlling excessive activity of neutrophil elastase. Our previous study revealed that PI3 gene expression is down-regulated during the acute stage of acute respiratory distress syndrome (ARDS). We conducted a case-control study to investigate whether genetic variants in PI3 gene are associated with ARDS development. Based on resequencing data from 29 unrelated white subjects, three tagging single-nucleotide polymorphisms were selected and genotyped in a prospective cohort consisting of 449 white patients with ARDS (cases) and 1,031 critically ill patients (at-risk control subjects). We found that the variant allele of rs2664581 (T34P) was significantly associated with increased ARDS risk (odds ratio [OR], 1.35; 95% confidence interval [Cl], 1.09-1.67; P = 0.006; false discovery rate adjusted P = 0.018). Moreover, this association was stronger among subjects with extrapulmonary injury. The common haplotype Hap2 (TTC), containing the variant allele of rs2664581, was also identified as a risk haplotype for ARDS (OR, 1.31; 95% Cl, 1.05-1.64; P = 0.015). Furthermore, the rs2664581 polymorphism was associated with circulating PI3 levels in multivariate analyses. Patients with ARDS homozygous for the wild-type A allele of rs2664581 showed significant lower PI3 plasma level (P = 0.019) at ARDS onset as compared with those homozygous or heterozygous for the variant Callele. Our data suggest that polymorphisms in PI3 gene are significantly associated with ARDS risk and with circulating PI3 levels.

Considerable variation in radiologic procedures, protocols, policies, and workflows exists across the nation, sometimes even within departments. This lack of standardization fosters idiosyncratic behavior and outcomes, undermining the effort to implement best practices across institutions. The purpose of this article is to discuss the need for rapidly implementing recognized standards and best practices when they exist. CONCLUSION. The use of information systems to monitor a wide variety of quality metrics offers managers the opportunity to standardize radiology and departmental practices, with the goal of transforming these practices into those that are more efficient and cost-effective and of higher quality.

TI Percutaneous CT-Guided Radiofrequency Ablation of Renal Cell Carcinoma: Efficacy of Organ Displacement by Injection of 5% Dextrose in Water Into the Retroperitoneum SO AMERICAN JOURNAL OF ROENTGENOLOGY LA English DT Article DE radiofrequency ablation; renal cell carcinoma ID 100 TUMORS; INJURY AB OBJECTIVE. The objective of this study was to evaluate the effectiveness of CT-guided injection of 5% dextrose in water solution (D5W) into the retroperitoneum to displace organs adjacent to renal cell carcinoma. MATERIALS AND METHODS. An interventional radiology database was searched to identify the cases of patients who underwent CT-guided percutaneous radiofrequency ablation of biopsy-proven renal cell carcinoma in which D5W was injected into the retroperitoneal space to displace structures away from the targeted renal tumor. The number of organs displaced and the distance between the renal tumor and adjacent organs before and after displacement with D5W were assessed. RESULTS. The cases of 135 patients with 139 biopsy-proven renal cell carcinomas who underwent 154 percutaneous CT-guided radiofrequency ablation procedures were found in the search. Thirty-one patients with 33 renal cell carcinomas underwent 36 ablation procedures after injection of D5W into the retroperitoneal space. Fifty-five organs were displaced away from renal cell carcinoma with this technique. The average distance between adjacent structures and renal cell carcinomas before displacement was 0.36 cm (range, 0.1-1.0 cm). The average distance between structures and adjacent renal cell carcinomas after displacement was 1.94 cm (range, 1.1-4.3 cm) (p < 0.0001). The average volume of D5W used to achieve organ displacement was 273.5 mL. No complications were associated with this technique. CONCLUSION. CT-guided injection of D5W into the retroperitoneum is an effective method for displacing vital structures away from renal cell carcinoma.

Even though a few biomechanical studies have compared the stability of the 2 fixation techniques, a clinical comparison has not yet been reported. Hypothesis: The authors hypothesized that both fixations would be identical in all studied clinical outcome measures at a minimum 2-year follow-up. Study Design: Cohort study; Level of evidence, 3. Materials and Methods: Thirty-three patients treated with either screw fixation (16 patients) or suture fixation (17 patients) within 1 month of the anterior cruciate ligament tibial avulsion fracture (type II or III) without associated ligamentous injury were included. All patients were evaluated at a minimum 2-year follow-up in terms of Lysholm knee scores and return to preinjury activities. Knee stability was compared based on the Lachman test and stress radiography. Results: No significant differences were found between the 2 groups in terms of average Lysholm knee scores (91.7 in the screw group and 92.7 in the suture group, P = .413) at follow-up. All patients except 2 (1 in each group) returned to preinjury activity levels. However, flexion contractures (5 degrees to 10 degrees) were found in 3 patients in the screw group and 2 patients in the suture group without significant intergroup difference. Stabilities based on the Lachman test and instrumented stress radiography were also similar between the 2 groups at follow-up. However, 2 patients in the screw group and 1 in the suture group showed more than 5 mm laxity compared with the contralateral knee on stress radiographs. Conclusion: Both the screw and suture fixation techniques for the anterior cruciate ligament tibial avulsion fracture produced relatively good results in terms of functional outcomes and stability without any significant differences. However, some patients in both groups showed residual laxity or flexion contractures.

Hypothesis: Current single-bundle PCL reconstruction is unable to correct the abnormal tibiofemoral and patellofemoral kinematics caused by rupture of the ligament. Study Design: Controlled laboratory study/case series; Level of evidence, 4. Methods: Seven patients with an isolated PCL injury in 1 knee and the contralateral side intact were included in the study. Magnetic resonance and dual fluoroscopic imaging techniques were used to compare the tibiofemoral and patellofemoral kinematics between the intact contralateral (control group), PCL-deficient, and PCL-reconstructed knee during physiologic loading with a single-legged lunge. Data were collected preoperatively and 2 years after single-bundle reconstruction. Results: The PCL reconstruction reduced the abnormal posterior tibial translation in PCL-deficient knees to levels not significantly different from those of the intact knee. Posterior cruciate ligament deficiency resulted in an increased lateral tibial translation between 75 degrees and 120 degrees of flexion, and reconstruction was unable to restore these values to normal. No differences were detected among the groups in varus-valgus and internal-external rotation. The PCL reconstruction reduced the increased patellar flexion of PCL-deficient knees between 90 degrees and 120 degrees of knee flexion and the lateral shift at 120. The abnormal patellar rotation and tilt seen in PCL deficiency at flexion angles of 75 degrees and greater persisted after reconstruction. Conclusion: Single-bundle PCL reconstruction was successful in restoring normal anteroposterior translation of the tibia, as well as the patellar flexion and shift. However, single-bundle PCL reconstruction was unable to achieve the same success in mediolateral translation of the tibia or in the patellar rotation and tilt. Clinical Relevance: The persistent abnormal mediolateral translation of the tibia, as well as decreased patellar rotation and tilt, provide a possible explanation for the development of cartilage degeneration after reconstruction of an isolated PCL injury.

Loss of expression of a Carney complex gene, cyclic adenosine 3',5' monophosphate-dependent protein kinase regulatory subunit 1 alpha, is observed in the majority of PEMs. Initial reports with short-term follow-up have suggested that although PEMs frequently metastasize to lymph nodes. they have a more favorable outcome than conventional Melanomas. In this report, we present the results of long-term Follow-up in 26 patients with PEMs from North America and Australia. There were 9 males and 17 females, with a median age of 20 years. The tumors involved the trunk (6 cases), extremities (12 cases), genitalia (1 case), and the head and neck region (7 cases) had a median Breslow thickness of 2.2 mm (range 0.80 to 10.0 mm) and a median Clark level of 4. Eight of the patients developed lymph node metastases. After a median follow-up period of 67 months (range 39 to 216mo), all patients are alive and free of disease. These findings provide further evidence that PEM is a unique low-grade melanocytic tumor with limited metastatic potential (to lymph nodes), but a favorable long-term clinical course.

TI Results of Gal-Knockout Porcine Thymokidney Xenografts SO AMERICAN JOURNAL OF TRANSPLANTATION LA English DT Article DE Baboon; GalT-KO; life-supporting renal grafts; thymus; xenotransplantation ID PIG THYMUS GRAFTS; MINIATURE SWINE; ALPHA-1,3-GALACTOSYLTRANSFERASE GENE; NONHUMAN-PRIMATES; NUCLEAR TRANSFER; T-CELLS; TRANSPLANTATION; TOLERANCE; XENOTRANSPLANTATION; INDUCTION AB Clinical transplantation for the treatment of end-stage organ disease is limited by a shortage of donor organs. Successful xenotransplantation could immediately overcome this limitation. The development of homozygous a 1,3-galactosyltransferase knockout (GalT-KO) pigs removed hyperacute rejection as the major immunologic hurdle to xenotransplantation. Nevertheless, GalT-KO organs stimulate robust immunologic responses that are not prevented by immunosuppressive drugs. Murine studies show that recipient thymopoiesis in thymic xenografts induces xenotolerance. We transplanted life-supporting composite thymokidneys (composite thymus and kidneys) prepared in GalT-KO miniature swine to baboons in an attempt to induce tolerance in a preclinical xenotransplant model. Here, we report the results of seven xenogenic thymokidney transplants using a steroid-free immunosuppressive regimen that eliminated whole-body irradiation in all but one recipient. The regimen resulted in average recipient survival of over 50 days. This was associated with donor-specific unresponsiveness in vitro and early baboon thymopoiesis in the porcine thymus tissue of these grafts, suggesting the development of T-cell tolerance. The kidney grafts had no signs of cellular infiltration or deposition of IgG, and no grafts were lost due to rejection. These results show that xenogeneic thymus transplantation can support early primate thymopoiesis, which in turn may induce T-cell tolerance to solid organ xenografts. C1 [Griesemer, A.

Recent in vitro evidence suggests that innate signaling may also contribute to immunity by countering the effects of regulatory T cells (T-regs), counter-regulation. We present in vivo evidence using a transgenic skin allograft model that the function of T-regs is lost in the setting of acute skin transplantation but remains intact when grafts were transplanted 1 month prior to allow surgery-induced inflammation to abate. Our findings identify T-reg counter-regulation as a naturally occurring process that accompanies transplantation and an important barrier to T-reg-mediated tolerance. Our finding further highlights the central role of regulatory cell deactivation in the initiation of the immune response. C1 [Kim, J. I.; Duff, P. E.; O'Connor, M. R.; Yeh, H.; Lian, M.

Dissemination of the parasite to lymph nodes was faster, and the subsequent infectivity to sand flies higher, in the IV compared with ID-infected dogs. Parasite-specific IgG1 or IgG2 production was similar among the groups, but higher interferon-gamma (IFN-gamma) and interleukin-10 (IL-10) expression was associated with polysymptomatic dogs. On the basis of the data obtained from this study, a sample size analysis using different endpoints for future vaccine trials is described.

TI Typing and susceptibility of bacterial isolates from the fidaxomicin (OPT-80) phase II study for C. difficile infection SO ANAEROBE LA English DT Article; Proceedings Paper CT 9th Biennial Congress of the Anaerobe-Society-of-the-Americas CY JUN 24-27, 2008 CL Long Beach, CA SP Anaerobe Soc Amer DE Clostridium; Difficile; OPT-80; Fidaxomicin; PAR-101; CDI ID IN-VITRO ACTIVITIES; CLOSTRIDIUM-DIFFICILE; METRONIDAZOLE; EPIDEMIC; DIARRHEA; DISEASE; AGENTS; STRAIN AB Background: Clostridium difficile infection (CDI) has been increasing in incidence and severity in recent years, coincident with the spread of a "hypervirulent" strain, REA type BI (ribotype 027, PFGE NAP 1). Exacerbating the problem has been the observation that metronidazole may be showing decreased effectiveness, particularly in the more severe cases. Fidaxomicin is an 18-membered macrocycle currently in phase 3 trials for the treatment of C. difficile infection (CDI). An open-label, phase II study in CDI patients has been completed and the clinical results published. C. difficile organisms were isolated from patient stool specimens and typed by restriction endonuclease analysis (REA) in order to determine the frequency and susceptibility of the C. difficile isolates and their response to treatment. Methods: Fecal samples were plated on CCFA agar for isolation of C. difficile. These isolates were tested for susceptibility to fidaxomicin, vancomycin, and metronidazole using CLSI agar dilution methods and were typed by REA. Results: C. difficile was isolated from 38 of 49 subjects and 16 (42%) were the epidemic C. difficile BI group. The BI strain was distributed approximately equally in the three dosing groups. Overall antibiotic susceptibilities were consistent with the previously reported MIC(90) values for the three antibiotics tested, but the MIC(90) of BI strains was two dilutions higher than non-BI strains for metronidazole and vancomycin (for both antibiotics, MIC(90) was 2 mu g/mL vs. 0.5 mu g/ml, P < 0.01 for metronidazole, P = NS for vancomycin). Clinical cure for BI isolates (11/14, 79%) was not significantly different from non-BI isolates (21/22, 95%). Conclusion: These results underscore the high prevalence of the BI epidemic strain and demonstrate that mild to moderate CDI infection as well as severe disease can be caused by these strains. Fidaxomicin cure rates for subjects with BI and with non-BI strains are similar, although the small numbers of subjects preclude a robust statistical comparison. (C) 2009 Elsevier Ltd.

Despite a clear pathogenic role for mutant huntingtin, understanding huntingtin expression during the presymptomatic phase of the disease or during disease progression has remained obscure. Central to clarifying the role in the pathomechanism of disease is the ability to easily and accurately measure mutant huntingtin in accessible human tissue samples as well as cell and animal models. Here we describe a highly sensitive time-resolved Forster resonance energy transfer (FRET) assay for quantification of soluble mutant huntingtin in brain, plasma, and cerebrospinal fluid. Surprisingly, in mice, soluble huntingtin levels decrease during disease progression, inversely correlating with brain aggregate load. Mutant huntingtin is easily detected in human brain and blood-derived fractions, providing a utility to assess mutant huntingtin expression during disease course as well as a pharmacodynamic marker for disease-modifying therapeutics targeting expression, cleavage, or degradation of mutant huntingtin. The design of the homogeneous one-step method for huntingtin detection is such that it can be easily applied to measure other proteins of interest. (C) 2009 Elsevier Inc. All rights reserved.

We reviewed the available literature exploring neuraxial techniques in parturients with uncorrected or corrected (i.e., surgically instrumented) scoliosis. The 22 articles reported 117 attempted neuraxial procedures (uncorrected n = 24 and corrected n = 93). Of these procedures, 79% of uncorrected patients and 69% of corrected patients were successfully managed with neuraxial anesthesia. Procedures were typically more challenging in corrected patients; 90% of all reported difficulties in this subgroup involved epidural anesthetics. Complications were reported in 3 of 103 patients. We provide suggestions for optimizing efficacy of neuraxial techniques in these patients.

Objective: To examine the influence of latitude (a marker of sunlight/vitamin D status) as a contributor to anaphylaxis in Australia, with a focus on children from birth to the age of 4 years. Methods: Epinephrine autoinjector (EpiPen) prescriptions (2006-2007) in 59 statistical divisions and anaphylaxis hospital admission rates (2002-2007) in 10 regions were used as surrogate markers of anaphylaxis. Results: EpiPen prescription rates (per 100,000 population per year) were higher in children from birth to the age of 4 years (mean, 951) than in the overall population (mean, 324). In an unadjusted model of children from birth to the age of 4 years, decreasing, absolute latitude was associated with a decrease in EpiPen prescription rates, such that rates were higher in southern compared with northern regions of Australia (beta, -44.4; 95% confidence interval. -57.0 to -31.8, P < .001). Adjusting forage. sex, ethnicity, indexes of affluence, education, or access to medical care (general, specialist allergy, or pediatric) did not attenuate the finding (beta, -51.9; 95% confidence interval. -71.0 to -32.9; P < .001). Although statistical power was limited, anaphylaxis admission rates (most prominent in children aged 0-4 years) showed a similar south-north gradient. such that admission rates were hi-her in Southern compared with northern regions of Australia Conclusions: EptPen prescription rates kind anaphylaxis admissions are more common in southern regions of Australia. These data provide additional support for a possible role of vitamin D in the pathogenesis of anaphylaxis.

Although multiple studies have been conducted in tertiary care emergency departments (EDS), scarce data are available about the presentation and management of ACE-I-induced angioedema (AIIA) in the community hospital ED. Objective: To describe the frequency, presentation, and management of AIIA in patients seen in a community hospital ED. Methods: A 5-year medical record review of all patients seen with angioedema at a community hospital ED. Data abstraction focused on demographic factors, initial clinical characteristics, and ED management and disposition of patients with AIIA. Results: We identified 166 ED visits for angioedema, including a subset of 50 visits for AIIA (30%, 95% confidence interval, 23%-38%). The AIIA was significantly more likely to be associated with an age of 65 years or older (P = .02.). unilateral symptoms (P = .02), and absence of urticaria or itching (P < .001). The ED treatment choices and admission rates were similar between patients with and without AIIA Community hospital admission rates for AIIA (14%) were significantly lower than those from a comparable tertiary care Study (41%) (P = .003) ambulance transport to the ED was nearly 3-fold higher in the tertiary care center study (P = .006). Admission was most strongly related to lack of improvement (P < .001) and history of angioedema in AIIA (P = .009). Conclusions: Angioedema frequency, presentation, and management are similar in community and tertiary care EDs (30%). Urticaria or itching may help differentiate AIIA from allergic reactions, which are otherwise similar in community ED presentation and management. Ann Allergy Asthma Immunol. 2009;103 502-507.

TI Predictors of 30-Day Serious Events in Older Patients With Syncope SO ANNALS OF EMERGENCY MEDICINE LA English DT Article ID EMERGENCY-DEPARTMENT; UNEXPLAINED SYNCOPE; RISK STRATIFICATION; SHORT-TERM; PROSPECTIVE VALIDATION; CLINICAL PREDICTORS; DIAGNOSING SYNCOPE; RULE; MANAGEMENT; POPULATION AB Study objective: We identify predictors of 30-day serious events after syncope in older adults. Methods: We reviewed the medical records of older adults (age >= 60 years) who presented with syncope or near syncope to one of 3 emergency departments (EDs) between 2002 and 2005. Our primary outcome was occurrence of a predefined serious event within 30 days after ED evaluation. We used multivariable logistic regression to identify predictors of 30-day serious events. Results: Of 3,727 potentially eligible patients, 2,871 (77%) met all eligibility criteria. We excluded an additional 287 patients who received a diagnosis of a serious clinical condition while in the ED. In the final study cohort (n=2,584), we identified 173 (7%) patients who experienced a 30-day serious event. High-risk predictors included age greater than 90 years, male sex, history of an arrhythmia, triage systolic blood pressure greater than 160 mm Hg, abnormal ECG result, and abnormal troponin I level. A low-risk predictor was a complaint of near syncope rather than syncope. A risk score, generated by summing high-risk predictors and subtracting the low-risk predictor, can stratify patients into low- (event rate 2.5%; 95% confidence interval [CI] 1.4% to 3.6%), intermediate- (event rate 6.3%; 95% CI 5.1% to 7.5%), and high-risk (event rate 20%; 95% CI 15% to 25%) groups. Conclusion: We identified predictors of 30-day serious events after syncope in adults aged 60 years and greater. A simple score was able to stratify these patients into distinct risk groups and, if externally validated, might have the potential to aid ED decisionmaking.

METHOD: The 1996 Health and Retirement Study cohorts were followed prospectively to 2004 (N = 8,377). Gender-stratified grouped Cox models were used to estimate the difference in the relative risk (RR) of mortality between a specific number of financial hardships (one, two, or three or more) and no hardships; and the predictive utility of each individual financial hardship for mortality during the follow-up period. RESULTS: Gender-stratified models adjusted for demographics, socioeconomic characteristics, and functional limitations in 1996 showed that women reporting one (hazard ratio [HR] = 1.42; 95% confidence interval [CI]: 1.05-1.92) or three or more (HR = 1.60; 95% CI: 1.05-2.46) and men reporting two (HR = 1.80; 95% CI: 1.21-2.69) financial hardships had a substantially higher probability of mortality compared to those reporting no financial hardships. Individual financial hardships that predicted mortality in fully adjusted models for women included receiving Medicaid (HR = 2.23; 95% CI: 1.68-2.98) and for men receiving Medicaid (HR = 2.11; 95% CI: 1.57-2.84) and receiving food stamps (HR = 1.59; 95% CI: 1.09-2.33). CONCLUSIONS: These findings suggest that over and above the influence of traditional measures of socioeconomic status, financial hardship exerts an influence on the risk of mortality among older adults and that the number and type of hardships important in predicting mortality may differ for men and women.

TI Primary follicular and marginal-zone lymphoma of the breast: clinical features, prognostic factors and outcome: a study by the International Extranodal Lymphoma Study Group SO ANNALS OF ONCOLOGY LA English DT Article DE breast malignancies; follicular lymphomas; MZLs; primary extranodal lymphomas ID NON-HODGKINS-LYMPHOMA; B-CELL LYMPHOMA; TERM-FOLLOW-UP; STAGE-I; CHEMOTHERAPY; RITUXIMAB; THERAPY; MODEL AB Patients and methods: Patients with histologically proven, previously untreated follicular or marginal-zone PBL (MZL PBL) diagnosed from 1980 to 2003 were included in the study. Major end points were progression-free survival (PFS), overall survival (OS) and potential prognostic factors. Results: We collected data on 60 cases of PBL [36 follicular and 24 marginal-zone lymphoma (MZL)]. Stage was I-E or IIE in 57 patients and IVE in three patients due to bilateral breast involvement. Surgery, chemotherapy and radiotherapy (RT), alone or in combination, were used as first-line treatments in 67%, 42% and 52% of patients, respectively. Overall response rate was 98%, with a 93% complete response rate. Five-year PFS were 56% for MZL and 49% for follicular PBL (P = 0.62). Relapses were mostly in distant sites (18 of 23 cases); no patients relapsed within RT fields. Conclusions: Our data showed an indolent behaviour of MZL PBL, comparable to other primary extranodal MZL. Conversely, patients with follicular PBL had inferior PFS and OS when compared with limited-stage nodal follicular non-Hodgkin's lymphomas, suggesting an adverse prognostic role of primary breast localisation in this histological subgroup.

TI Communication Practices on 4 Harvard Surgical Services A Surgical Safety Collaborative SO ANNALS OF SURGERY LA English DT Article ID OPERATING-ROOM; PATIENT-CARE; RESIDENTS; SURGEONS; ERRORS AB Background: Communication breakdowns between surgical residents and attending physicians in the pre- and postoperative setting are common contributors to patient injury. These communication transactions might offer an opportunity for safety improvement, but it remains unknown how often resident-attending communi cation fails, what the current level of attending involvement is, and how often attending input changes the plan for patient care. We conducted a prospective study at 4 Harvard teaching It hospitals to address these issues. Methods: Three prospective data collection strategies were employed: (1) we randomly selected surgical services and queried residents for the occurrence of predefined critical patient events and the characteristics of attending communications that ensued, (2) on weekends, randomly selected patients were interviewed and their charts reviewed to identify the frequency of attending visitation and how such visits affected processes of care, and (3) on weekends, senior residents on randomly selected surgical services were queried regarding the occurrence of attending-resident discussion of patients in their care. Results: Of 80 critical patient events identified, 26 (33%) were not communicated to attending surgeons. Residents reported that, when contacted, all attending physicians were receptive to communication, whether they were the primary surgeon or providing cross-coverage. Although residents felt that attending contact was unnecessary for safe patient care in 61 (76%) of these events, discussions with attending physicians changed management in 33% (18/54) of cases in which they occurred. Attending surgeons were found to visit their patients on randomly selected weekend days 42% (n = 37) of the time, while 21% (n = 19) had not visited for 2 or greater days. When attending physicians visited patients, however, resident management was modified 46% (n = 36) of the time. Though residents frequently discussed patient management with attending physicians on randomly selected weekends, they failed to do so 16% (n = 58) of the time, which appeared to be related to service-specific variation (chi(2) = 269, P < 0.0001). Conclusions: In the context of both critical patient events and routine patient care, residents often fail to obtain attending surgeons' input for management decisions. These failures seem to derive more from residents' perception of necessity than from attending physicians' receptiveness or interest in being contacted. Once involved, attending physicians frequently modify resident's management decisions. It seems, therefore, that there is significant potential for communication failure and information loss among our 4 institutions.

TI Variability in Length of Stay After Colorectal Surgery Assessment of 182 Hospitals in the National Surgical Quality Improvement Program SO ANNALS OF SURGERY LA English DT Article ID QUALITY IMPROVEMENT PROGRAM; MEDICAL-CARE; OUTCOMES; SATISFACTION; PERFORMANCE; INFECTION AB Background: Length of postoperative stay (LOS) has gained increasing attention as a potential indicator of surgical efficiency. Our objective was to examine the feasibility of assessing LOS at 182 hospitals to identify institutions with outlying performance. Methods: Patients were identified who underwent colorectal surgery at 182 hospitals participating in the American College of Surgeon's National Surgical Quality Improvement Program (ACS NSQIP) from 2006 to 2007. Regression models for extended LOS (greater than the 75th percentile) were developed to identify hospitals whose ratios of observed to expected events (O/E) were significantly better (low outlier) or worse (high outlier) than expected after adjustment for case mix. To evaluate strategies for evaluating LOS that would be minimally influenced by the occurrence of complications, separate models were developed for patients categorized either by (1) the nonoccurrence or occurrence of any postoperative complication or (2) tercile of preoperative morbidity risk. Results: The 23,098 patients selected for this study were partitioned into groups without complications (0% complications), with complications (100%) or into terciles of preoperative morbidity risk (with 22.4%, 38.7%, and 60.0% of patients having complications, respectively). In general, the greater the complication rate the longer the LOS and the fewer the number of statistical outliers that were identified. Conclusions: ACS NSQIP data can provide individual hospitals with risk-adjusted LOS measures that can be used to identify outlying performance and motivate quality improvement efforts.

TI Three-Dimensional Echocardiographic Assessment of Changes in Mitral Valve Geometry After Valve Repair SO ANNALS OF THORACIC SURGERY LA English DT Article ID TRANSESOPHAGEAL ECHOCARDIOGRAPHY; ANNULAR SHAPE; INTRAOPERATIVE MULTIPLANE; LEAFLET CURVATURE; RING SELECTION; SINGLE-PLANE; OVINE MODEL; REGURGITATION; ANNULOPLASTY; RECONSTRUCTION AB Background. Application of annuloplasty rings during mitral valve (MV) repair has been shown to significantly change the mitral annular geometry. Until recently, a comprehensive two-dimensional echocardiographic evaluation of annular geometric changes was difficult owing to its nonplanar orientation. In this study, an analysis of the three-dimensional intraoperative transesophageal echocardiographic evaluation of the MV annulus is presented before and immediately after repair. Methods. We performed three-dimensional geometric analysis on 75 patients undergoing MV repair during coronary artery bypass graft surgery for mitral regurgitation or myxomatous mitral valve disease. Geometric analysis of the MV was performed before and immediately after valve repair with full rings and annuloplasty bands. The acquired three-dimensional volumetric data were analyzed in the operating room. Specific measurements included annular diameter, leaflet lengths, the nonplanarity angle, and the circularity index. Before and after repair data were compared. Results. Complete echocardiographic assessment of the MV was feasible in 69 of 75 patients (92%) within 2 to 3 minutes of acquisition. Placement of full rings resulted in an increase in the nonplanarity angle or a less saddle shape of the native mitral annulus (137 +/- 14 versus 146 +/- 14; p = 0.002. By contrast, the nonplanarity angle did not change significantly after placement of partial rings. Conclusions. Mitral annular nonplanarity can be assessed in the operating room. Application of full annuloplasty rings resulted in the mitral annulus becoming more planar. Partial annuloplasty bands did not significantly change the nonplanarity angle. Neither of the two types of rings restored the native annular planarity. C1 Beth Israel Deaconess Med Ctr, Dept Anesthesia & Crit Care & Pain Management, Cardiovasc Inst, Boston, MA 02215 USA.

TI Energy Loss Due to Paravalvular Leak With Transcatheter Aortic Valve Implantation SO ANNALS OF THORACIC SURGERY LA English DT Article ID HEART-VALVE; HEMODYNAMIC PERFORMANCE; MITRAL REGURGITATION; STENOSIS; FEASIBILITY; REPLACEMENT; EXPERIENCE; PROSTHESIS AB Background. Mild to moderate paravalvular leaks commonly occur after transcatheter aortic valve (TAV) implantation. Current TAVs match and may exceed hemodynamic performance of surgically implanted bioprostheses based on pressure gradient and effective orifice area. However, these hemodynamic criteria do not account for paravalvular leaks. We recently demonstrated that TAV implantation within 23 mm Perimount bioprostheses (Edwards Lifesciences, Irvine, CA) yields similar hemodynamics to the 23 mm Perimount valve. However, mild paravalvular leakage was seen after TAV implantation. The present study quantifies energy loss during the entire cardiac cycle to assess the impact of TAV paravalvular leaks on the ventricle. Methods. Four TAVs designed to mimic the 23 mm SAPIEN valve (Edwards Lifesciences) were created. Transvalvular energy loss of 19, 21, and 23 mm Carpentier-Edwards bioprostheses were obtained in vitro within a pulse duplicator as a hemodynamic baseline (n = 4). The 23 mm TAVs were subsequently implanted within the 23 mm bioprostheses to assess energy loss due to paravalvular leak. Results. The 23 mm bioprosthesis demonstrated the least energy loss (213.25 +/- 31.35 mJ) compared with the 19 mm (330.00 +/- 36.97 mJ, p = 0.003) and 21 mm bioprostheses (298.00 +/- 37.25 mJ, p = 0.008). The TAV controls had similar energy loss (241.00 +/- 30.55 mJ, p = 0.17) as the 23 mm bioprostheses. However, after TAV implantation, total energy loss increased to 365.33 +/- 8.02 mJ significantly exceeding the energy loss of the 23 mm bioprosthesis (p < 0.001). Due to mild TAV paravalvular leakage, 39% of energy loss occurred during diastole. Conclusions. Substantial energy loss during diastole occurs due to TAV paravalvular leakage. In the presence of mild paravalvular leakage, TAV implantation imposes a significantly higher workload on the left ventricle than an equivalently sized surgically implanted bioprosthesis.

TI Valve-in-Valve Implantation Using a Novel Supravalvular Transcatheter Aortic Valve: Proof of Concept SO ANNALS OF THORACIC SURGERY LA English DT Article ID EDWARDS PERICARDIAL BIOPROSTHESIS; FAILURE MODES; HEART-VALVE; REPLACEMENT; STENOSIS; POSITION; SURGERY AB Background. Transcatheter valve implantation within degenerated bioprostheses is a potentially promising treatment for high-risk surgical patients. Clinical experience is limited; however, we have shown in vitro that currently available transcatheter aortic valve sizes did not provide acceptable hemodynamics in small bioprostheses. The objective of this study was to develop a new transcatheter valve that would provide good hemodynamics within degenerated bioprostheses. Methods. Supravalvular transcatheter valves were created using a Dacron covered stainless steel stent at the base and trileaflet pericardial leaflets in an open stent above the bioprosthesis. The transcatheter valves were implanted within 19-, 21-, and 23-mm Carpentier-Edwards Perimount bioprostheses with simulated degeneration using BioGlue to achieve a mean pressure gradient of 50 mm Hg. Hemodynamics of valve-in-valve implantation were studied in a pulse duplicator. Results. Supravalvular transcatheter valves successfully relieved bioprosthetic stenosis. Acceptable hemodynamics were achieved with a significant reduction in mean pressure gradient of 54.0 +/- 3.5 to 9.2 +/- 6.3 mm Hg in 23-mm bioprostheses (p < 0.001), from 49.3 +/- 3.1 to 14.4 +/- 4.7 mmHg (p < 0.001) in 21 mm, and from 53.9 +/- 3.8 to 28.3 +/- 9.8 mm Hg (p = 0.013) in 19-mm bioprostheses. Effective orifice area after valve-in-valve implantation increased significantly and was comparable to rereplacement with the same size bioprosthesis. Conclusions. Valve-in-valve implantation was performed using a novel supravalvular transcatheter valve, which successfully relieved bioprosthetic stenosis. The hemodynamics were comparable with standard surgical valve replacement. Further studies are required to assess device safety and efficacy in patients.

Insufficient expression of genes that regulate viability of the progenitor cells is responsible for the apoptosis. In particular, maternal diabetes inhibits expression of a gene, Pax3, that encodes a transcription factor which is expressed in neural crest and neuroepithelial cells. As a result of insufficient Pax3, cardiac neural crest and neuroepithelial cells undergo apoptosis by a process dependent on the p53 tumor suppressor protein. This, then provides a cellular explanation for the cardiac outflow tract and neural tube and defects induced by diabetic pregnancy.

A subset of ALS cases are linked to dominant mutations in copper-zinc superoxide dismutase (SOD1). The pathogenic SOD1 variants A4V and G93A have been the foci of multiple Studies aimed at understanding the molecular basis for SOD1-linked ALS. The A4V variant is responsible for the majority of familial ALS cases in North America, causing rapidly progressing Paralysis once symptoms begin and the G93A SOD1 variant is overexpressed in often studied murine models of the disease. Here we report the three-dimensional structures of metal-free A4V and of metal-bound and metal-free G93A SOD1. In the metal-free structures, the metal-binding loop elements are observed to be severely disordered, suggesting that these variants may share mechanisms of aggregation proposed previously for other pathogenic SOD1 proteins.

TI Functional Neuroanatomy of Visual Masking Deficits in Schizophrenia SO ARCHIVES OF GENERAL PSYCHIATRY LA English DT Article ID EVENT-RELATED FMRI; MULTIPLE TRIAL TYPES; BACKWARD-MASKING; UNAFFECTED SIBLINGS; OBJECT RECOGNITION; OCCIPITAL CORTEX; PERFORMANCE; CHANNELS; REPRESENTATION; VULNERABILITY AB Context: Visual masking procedures assess the earliest stages of visual processing. Patients with schizophrenia reliably show deficits on visual masking, and these procedures have been used to explore vulnerability to schizophrenia, probe underlying neural circuits, and help explain functional outcome. Objective: To identify and compare regional brain activity associated with one form of visual masking (ie, backward masking) in schizophrenic patients and healthy controls. Design: Subjects received functional magnetic resonance imaging scans. While in the scanner, subjects performed a backward masking task and were given 3 functional localizer activation scans to identify early visual processing regions of interest (ROIs). Setting: University of California, Los Angeles, and the Department of Veterans Affairs Greater Los Angeles Healthcare System. Participants: Nineteen patients with schizophrenia and 19 healthy control subjects. Main Outcome Measure: The magnitude of the functional magnetic resonance imaging signal during backward masking. Results: Two ROIs (lateral occipital complex [LO] and the human motion selective cortex [hMT vertical bar]) showed sensitivity to the effects of masking, meaning that signal in these areas increased as the target became more visible. Patients had lower activation than controls in LO across all levels of visibility but did not differ in other visual processing ROIs. Using whole-brain analyses, we also identified areas outside the ROIs that were sensitive to masking effects (including bilateral inferior parietal lobe and thalamus), but groups did not differ in signal magnitude in these areas. Conclusions: The study results support a key role in LO for visual masking, consistent with previous studies in healthy controls. The current results indicate that patients fail to activate LO to the same extent as controls during visual processing regardless of stimulus visibility, suggesting a neural basis for the visual masking deficit, and possibly other visual integration deficits, in schizophrenia.

Measures of intracranial tissue volume and cerebral tissue volume have been observed to be smaller in adolescents with maltreatment-related PTSD. Second, lower intelligence, a risk factor for PTSD, is associated with smaller cerebral tissue volumes. Nevertheless, to our knowledge, only 1 study has observed globally smaller cerebral tissue volume in adults with PTSD. Objectives: To apply a recently developed method providing improved estimates of cortical volume and to estimate associations between adult PTSD and selected regional cortical volumes not yet investigated. Design: Between-group comparison of global and regional cerebral cortical volumes in adult patients with combat-related PTSD and controls. Setting: Two Department of Veterans Affairs medical centers with large inpatient and outpatient PTSD catchments. Participants: Ninety-seven combat-exposed veterans of the Vietnam and Persian Gulf wars. Main Outcome Measure: Global and regional cortical volumes determined using the FreeSurfer software program and the Desikan et al parcellation (modified). Results: Cerebral cortical volume, thickness, and area were observed to be smaller in association with adult combat-related PTSD. Robust associations were observed between PTSD and smaller cortical volumes in the parahippocampal gyrus, superior temporal cortex, lateral orbital frontal cortex, and pars orbitalis of the inferior frontal gyrus. Conclusions: Cerebral cortical volume, thickness, and area may be smaller in adult chronic severe PTSD; however, the extracted structural variables did not mediate relations between intelligence and PTSD. The 4 regions exhibiting especially smaller cortical volumes in this sample share involvement in mechanisms subserving "topdown" facilitation of the identification of objects and words. Compromise of these regions may result in difficulty in relearning pretrauma schemata for interpreting the civilian physical and social environments.

CA Parkinson Study Grp DATATOP TI Urate as a Predictor of the Rate of Clinical Decline in Parkinson Disease SO ARCHIVES OF NEUROLOGY LA English DT Article ID SERUM URIC-ACID; NUTRITION EXAMINATION SURVEY; MILD COGNITIVE IMPAIRMENT; 3RD NATIONAL-HEALTH; VITAMIN-E; CEREBROSPINAL-FLUID; PLASMA URATE; CONCENTRATION GRADIENTS; ANTIOXIDANT CAPACITY; MULTIPLE-SCLEROSIS AB Background: The risk of Parkinson disease (PD) and its rate of progression may decline with increasing concentration of blood urate, a major antioxidant. Objective: To determine whether serum and cerebrospinal fluid concentrations of urate predict clinical progression in patients with PD. Design, Setting, and Participants: Eight hundred subjects with early PD enrolled in the Deprenyl and Tocopherol Antioxidative Therapy of Parkinsonism (DATATOP) trial. The pretreatment urate concentration was measured in serum for 774 subjects and in cerebrospinal fluid for 713 subjects. Main Outcome Measures: Treatment-, age-, and sex-adjusted hazard ratios (HRs) for clinical disability requiring levodopa therapy, the prespecified primary end point of the original DATATOP trial. Results: The HR of progressing to the primary end point decreased with increasing serum urate concentrations (HR for highest vs lowest quintile=0.64; 95% confidence interval [CI], 0.44-0.94; HR for a 1-SD increase=0.82; 95% CI, 0.73-0.93). In analyses stratified by alpha-tocopherol treatment (2000 IU/d), a decrease in the HR for the primary end point was seen only among subjects not treated with alpha-tocopherol (HR for a 1-SD increase=0.75; 95% CI, 0.62-0.89; vs HR for those treated=0.90; 95% CI, 0.75-1.08). Results were similar for the rate of change in the Unified Parkinson's Disease Rating Scale score. Cerebrospinal fluid urate concentration was also inversely related to both the primary end point (HR for highest vs lowest quintile=0.65; 95% CI, 0.44-0.96; HR for a 1-SD increase=0.89; 95% CI, 0.79-1.02) and the rate of change in the Unified Parkinson's Disease Rating Scale score. As with serum urate concentration, these associations were present only among subjects not treated with alpha-tocopherol. Conclusions: Higher serum and cerebrospinal fluid urate concentrations at baseline were associated with slower rates of clinical decline. The findings strengthen the link between urate concentration and PD and the rationale for considering central nervous system urate concentration elevation as a potential strategy to slow PD progression.

TI Unsatisfactory Reporting Rates 2006 Practices of Participants in the College of American Pathologists Interlaboratory Comparison Program in Gynecologic Cytology SO ARCHIVES OF PATHOLOGY & LABORATORY MEDICINE LA English DT Article ID CERVICOVAGINAL CYTOLOGY; SPECIMEN ADEQUACY; TERMINOLOGY AB Context.-Minimum cellular criteria for satisfactory Papanicolaou tests were established with the Bethesda System in 2001, and unsatisfactory rates are used as a quality-reporting measure. Objective.-To evaluate practices and unsatisfactory rates from laboratories responding to the 2007 College of American Pathologists supplemental questionnaire survey. Design.-In 2007, a supplemental questionnaire was mailed to 1621 laboratories enrolled in the 2006 College of American Pathologists Interlaboratory Comparison Program in Gynecologic Cytology (PAP Education), requesting data from the 2006 calendar year. Unsatisfactory rates, reasons for unsatisfactory specimens, laboratory size, and specimen preparation type were analyzed. Results.-A total of 42% of the laboratories responded to the survey. Most of those laboratories (637 of 674; 94.5%) used the Bethesda System minimum cellularity criteria. Of those laboratories responding, 79% (527 of 667) used the Bethesda System criteria for atrophic or postirradiation specimens. Unsatisfactory rates have increased since 1996. SurePath preparations were associated with the lowest unsatisfactory rate (50th percentile, 0.30; 95th percentile, 1.3), conventional Papanicolaou tests had the highest 95th percentile rates (50th percentile, 1.0; 95th percentile, 5.90), and ThinPrep specimens had the highest median percentile (50th percentile, 1.1; 95th percentile, 3.4). The most-common reason for unsatisfactory Papanicolaou tests was too few squamous cells. Air-drying artifact was the least-common reason for unsatisfactory reporting for liquid-based preparations. Conclusions.-Use of the Bethesda System criteria for unsatisfactory specimens is widespread. Unsatisfactory rates have increased since 1996; however, the median rates are 1.1% or less for all preparations. Results from the College of American Pathologists PAP Education supplemental questionnaire continue to provide valuable benchmarking data for cytologic quality-improvement programs in laboratories.

Isolated autopsy reports have described multiorgan involvement by this disease. Objective.-To further illustrate the varied and systemic involvement of NSF by describing the autopsy experience at the Massachusetts General Hospital. Design.-We describe the findings in a series of 4 autopsy cases of patients diagnosed with NSF. This report describes the history of renal dysfunction, exposure to gadolinium-containing contrast agents, specific laboratory parameters, and the extent of systemic involvement identified by postmortem examination. Results.-Causes of death included systemic thromboembolic disease (n = 3) and pneumonia (n = 1). Laboratory parameters and type, dose, or timing of gadolinium-containing contrast-agent exposure did not correlate with clinical findings and outcomes. All patients demonstrated cutaneous manifestations of the disease and nephrocalcinosis, with some exhibiting calcification and fibrosis of the dura, thyroid, and heart including the cardiac conduction system, on postmortem examination. Soft tissue calcification was associated with concurrent hyperparathyroidism or high serum parathyroid hormone levels. Conclusions.-Thromboembolic disease can be a significant clinical complication of NSF. Patients with NSF may also develop characteristic histologic features of fibrosis and calcification in multiple organs, with significant morbidity and mortality. This autopsy series highlights the variability of systemic manifestations of NSF.

Before implementation, technical issues, pathologist adaptability, and morphologic pitfalls must be well characterized. Objective.-To determine whether interpretation of whole-slide images differed from glass-slide interpretation in difficult surgical pathology cases. Design.-Diagnostically challenging pathology slides from a variety of anatomic sites from an outside laboratory were scanned into whole digital format. Digital and glass slides were independently diagnosed by 2 subspecialty pathologists. Reference, digital, and glass-slide interpretations were compared. Operator comments on technical issues were gathered. Results.-Fifty-three case pairs were analyzed. There was agreement among digital, glass, and reference diagnoses in 45 cases (85%) and between digital and glass diagnoses in 48 (91%) cases. There were 5 digital cases (9%) discordant with both reference and glass diagnoses. Further review of each of these cases indicated an incorrect digital whole-slide interpretation. Neoplastic cases showed better correlation (93%) than did cases of nonneoplastic disease (88%). Comments on discordant cases related to digital whole technology focused on issues such as fine resolution and navigating ability at high magnification. Conclusions.-Overall concordance between digital whole-slide and standard glass-slide interpretations was good at 91%. Adjustments in technology, case selection, and technology familiarization should improve performance, making digital whole-slide review feasible for broader telepathology subspecialty consultation applications.

TI Wheelchair Repairs, Breakdown, and Adverse Consequences for People With Traumatic Spinal Cord Injury SO ARCHIVES OF PHYSICAL MEDICINE AND REHABILITATION LA English DT Article DE Equipment failure; Reference standards; Rehabilitation; Spinal cord injuries; Wheelchairs ID ELECTRIC-POWERED WHEELCHAIRS; ANSI/RESNA STANDARDS; MAINTENANCE; DURABILITY; ACCIDENTS; SAFETY; USERS AB McClure LA, Boninger ML, Oyster ML, Williams S, Houlihan B, Lieberman JA, Cooper RA. Wheelchair repairs, breakdown, and adverse consequences for people with traumatic spinal cord injury. Arch Phys Med Rehabil 2009;90:2034-8. Objectives: To investigate the frequency of repairs that occurred in a 6-month period and the consequences of breakdowns on wheelchair users living with spinal cord injuries (SCIs), and to determine whether certain wheelchair and subject characteristics are associated with an increased number of repairs and adverse consequences. Design: Convenience sample survey. Setting: Sixteen Model Spinal Cord Injury Systems Centers that are part of the national database funded through the Department of Education, National Institute on Disability and Rehabilitation Research. Participants: People with SCI who use a wheelchair for more than 40h/wk (N=2213). Intervention: Not applicable. Main Outcome Measures: The frequency of wheelchair repairs and occurrence of adverse consequences caused by a wheelchair breakdown in a 6-month period. Results: Within a 6-month period, 44.8% of full-time wheelchair users completed a repair, and 8.7% had an adverse consequence occur. People who use power wheelchairs required significantly more repairs (P <.001), and adverse consequences occurred more frequently (P<.001) compared with manual wheelchair users. The presence of power seat functions, and a person's occupational status or sex did not influence the number of repairs or adverse consequences. Conclusions: Frequent repairs and breakdown can negatively impact a person's life by decreasing community participation and threatening health and safety. Mandatory compliance with the American National Standards Institute and the Rehabilitation Engineering and Assistive Technology Society of North America standards, changes in insurance reimbursement policy, and patient and clinician education are necessary to reduce the number of repairs and adverse consequences that occur.

Performance of common clinician- and self-report measures in assessing the function of community-dwelling people with metastatic breast cancer. Arch Phys Med Rehabil 2009;90:2116-24. Objective: To characterize the performance of common clinician- and self-report measures of function in assessing community-dwelling people with metastatic breast cancer. Design: Cross-sectional study. Setting: A tertiary medical center outpatient cancer clinic. Participants: A consecutive sample of community-dwelling patients (N=163) with stage IV breast cancer. Interventions: Not applicable. Main Outcome Measures: Medical Outcomes Study 36-Item Short-Form Physical Functioning (PF-10) and Role Physical subscales; the Older Americans Resource Study (OARS) activities of daily living (ADL) and instrumental ADL subscales; Karnofsky Performance Scale (KPS); and the FIM Total and FIM Mobility scores. Results: With the exception of the PF-10 and Role Physical subscales, which demonstrated floor effects, ceiling effects were detected in all the measures and were particularly persistent in the OARS ADL subscale. Instrument and item score distributions varied markedly across KPS-defined subgroups with FIM Mobility, FIM Total, and OARS subscale score distributions deviating least from the normal in the lowest performing (KPS 40-50) participants. Correlations between self-reported (Role Physical subscales, PF-10, OARS ADL subscales) and the clinician-rated (KPS and FIM scales) scales were moderate to high (r=.55-.82); however, clinician-reported scores were more consistently associated with the presence of physical impairments. Conclusions: In this population with stage IV breast cancer, ceiling effects limit the discriminatory capacity of the common functional scales assessed in this study. Instruments and items, particularly when ADL based, tend to perform better at lower levels of function (KPS 40-50) and less well at higher levels. Clinician-rated outcomes may have greater capacity to discriminate the presence of physical impairments.

To analyze the effect of lidocaine on postoperative pain relief, we performed compression of the right sciatic nerve in Wistar rats and observed the differences on behavior between the group that received lidocaine and the group that was not treated with the local anesthetics pre-operatively. Group I was not operated (control); group 2 underwent the sciatic nerve ligature without lidocaine; group 3, underwent surgery with previous local infiltration of lidocaine. Group 2 showed significantly longer scratching times with a peak on day 14 post-operative (p=0.0005) and reduction in the latency to both noxious (p=0.003) and non-noxious (p=0.004) thermal stimulus. Group 3 presented significantly shorter scratching times (p=0.004) and longer latency times when compared to Group 2. Preemptive use of lidocaine 2% can potentially reduce the postoperative neuropathic pain associated with sciatic nerve compression.

Pareidolia, the misperception of vague or obscure stimuli being perceived as something clear and distinct, is somewhat beneficial for the physician in the pursuit of diagnostic strategies. Animals may be pareidolically recognized in neuroimages according to the presence of specific diseases. By associating a given radiological aspect with an animal, doctors improve their diagnostic skills and reinforce mnemonic strategies in radiology practice. The most important pareidolical perceptions of animals in neuroimaging are the hummingbird sign in progressive supranuclear palsy, the panda sign in Wilson's disease, the panda sign in sarcoidosis, the butterfly sign in glioblastomas, the butterfly sign in progressive scoliosis and horizontal gaze palsy, the elephant sign in Alzheimer's disease and the eye-of-the-tiger sign in pantothenate kinase-associated neurodegenerative disease.

To investigate the in vivo cartilage contact biomechanics of the tibiofemoral joint following anterior cruciate ligament (ACL) injury. Methods. Eight patients with an isolated ACL injury in 1 knee, with the contralateral side intact, participated in the study. Both knees were imaged using a specific magnetic resonance sequence to create 3-dimensional models of knee bone and cartilage. Next, each patient performed a lunge motion from 0 degrees to 90 degrees of flexion as images were recorded with a dual fluoroscopic system. The three-dimensional knee models and fluoroscopic images were used to reproduce the in vivo knee position at each flexion angle. With this series of knee models, the location of the tibiofemoral cartilage contact, size of the contact area, cartilage thickness at the contact area, and magnitude of the cartilage contact deformation were compared between intact and ACL-deficient knees. Results. Rupture of the ACL changed the cartilage contact biomechanics between 0 degrees and 60 degrees of flexion in the medial compartment of the knee. Compared with the contralateral knee, the location of peak cartilage contact deformation on the tibial plateaus was more posterior and lateral, the contact area was smaller, the average cartilage thickness at the tibial cartilage contact area was thinner, and the resultant magnitude of cartilage contact deformation was increased. Similar changes were observed in the lateral compartment, with increased cartilage contact deformation from 0 degrees to 30 degrees of knee flexion in the presence of ACL deficiency. Conclusion. ACL deficiency alters the in vivo cartilage contact biomechanics by shifting the contact location to smaller regions of thinner cartilage and by increasing the magnitude of the cartilage contact deformation.

TI An Item-Level Psychometric Analysis of the Personality Assessment Inventory Clinical Scales in a Psychiatric Inpatient Unit SO ASSESSMENT LA English DT Article DE Personality Assessment Inventory (PAI); Multi-item Multi-trait Analysis Program; psychometric properties; personality assessment; psychiatric inpatients; inpatient assessment ID SELF-REPORT; PAI AB Multi-item multiscale self-report measures are increasingly used in inpatient assessments. When considering a measure for this setting, it is important to evaluate the psychometric properties of the clinical scales and items to ensure that they are functioning as intended in a highly distressed clinical population. The present study examines scale properties for a self-report measure frequently employed in inpatient assessments, the Personality Assessment Inventory (PAI). In addition to examining internal consistency statistics, this study extends prior PAI research by considering key issues related to inpatient assessment (e. g., scale distinctiveness, ceiling effects). Coefficient alphas, interitem correlations, and item-scale relationships suggest that the PAI clinical scales and subscales are internally consistent. Items for respective clinical scales generally showed significantly higher item-scale correlations with their intended scale (as compared with their item-scale correlation with scales they were not intended to measure). In addition, scales' coefficient alpha scores were higher than their interscale correlations. Taken as a whole, these results support the hypothesis that PAI scales were measuring relatively distinct constructs in this inpatient sample. Findings are discussed with regard to the implications for scale interpretation in inpatient assessment, functioning of individual scales and subscales, and functioning of specific items. Limitations of the present study and directions for future research are discussed. C1 [Siefert, Caleb J.] Massachusetts Gen Hosp, PEaRL, Boston, MA 02114 USA.

The presence of immune defects leading to synthesis of TSHR-Abs causes hyperthyroidism and is associated with other extrathyroidal manifestations. Further characterization of these antibodies has now been made possible by the generation of monoclonal antibodies with this unique stimulating capacity as well as similar TSHR-Abs not associated with hyperthyroidism. Their present classification divides TSHR-Abs into stimulating, blocking (competing with TSH binding) and neutral (no signaling). Recent studies using monoclonal TSHR-Abs has revealed that stimulating and blocking antibodies bind to the receptor using mostly conformational epitopes, whilst neutral antibodies utilize exclusively linear peptides. Subtle differences in epitopes for stimulating and blocking antibodies account for the diversity of their biological actions. Recently non-classical signaling elicited by neutral antibodies has also been described, raising the need for a new classification of TSHR-Abs. Published by Elsevier B.V.

Given its robust association with relapse, EE has become a major target of family psychoeducational interventions. Most psychoeducational interventions to date have failed to change EE levels among families of those with bipolar disorder. Better intervention strategies, then, may depend on an increased understanding of the predictors of EE. Although EE has traditionally included many facets, criticism appears to be the most robust predictor of outcome within bipolar disorder. The present study tested three primary predictors of criticism among family members of people with bipolar disorder: shame-proneness, guilt-proneness, and depression. Depressive symptoms were significantly associated with EE. Discussion focuses on limitations and implications of the study and suggestions for future research.

However, the majority of these studies used methods not suited to differentiating difficulty disengaging attention from threatening stimuli (interference) from facilitated detection of threat. In the current study, a visual search task (VST) with a lexical decision component was used to differentiate between attentional interference and facilitation. Forty-six sexual assault survivors with High PTSD or Low PTSD symptoms completed the VST with three types of stimuli (trauma-related, general threat-related, and semantically-related neutral words), to examine the specificity of attentional biases associated with PTSD symptoms. High PTSD participants showed increased interference to trauma-related words relative to Low PTSD participants. Furthermore, the increased attentional interference in High PTSD participants was specific to trauma-related stimuli. No evidence was found for facilitated detection of threatening stimuli in PTSD. These results provide additional support for attentional biases in PTSD relating to attentional interference with trauma-related cues rather than facilitated detection of threat. The implications for this pattern of results are discussed in relation to anxiety disorders that are characterized by rumination and/or intrusions (e.g., PTSD, GAD) rather than those more circumscribed to fight or flight response (e.g., phobias).

Following extinction of a cocaine CPP, rats were administered modafinil (128 mg/kg), cocaine (5 mg/kg) or vehicle and given a 60-min reinstatement test. While the effect of cocaine was transient, modafinil robustly reinstated a cocaine CPP following extinction, suggesting that modafinil may induce relapse or increase the vulnerability of addicts to the reinforcing effects of environmental triggers.

In some cases interferon induced thyroiditis (IIT) may result in severe symptomatology necessitating discontinuation of therapy. IIT can manifest as clinical autoimmune thyroiditis, presenting with symptoms of classical Hashimoto's thyroiditis or Graves' disease, or as non-autoimmune thyroiditis Non-autoimmune thyroiditis can manifest as destructive thyroiditis, with early thyrotoxicosis and later hypothyroidism. or as non-autoimmune hypothyroidism While the epidemiology and clinical presentation of IIT have been well characterized the mechanisms causing IIT still poorly understood. It is likely that the hepatitis C Virus (HCV) itself plays a role in the disease, as the association between HCV infection and thyroiditis is well established. It is believed that IFN alpha. induces thyroiditis by both immune stimulatory effects and by direct effects on the thyroid. Early detection and therapy of this condition are Important in order to avoid complications of thyroid disease such as cardiac arrhythmias. (C) 2009 Elsevier Ltd All rights reserved.

CerS2 (ceramide synthase 2) is one of the six mammalian isoforms of ceramide synthase and is responsible for the synthesis of VLC (very-long-chain) ceramides, e.g. C(24), C(24:1). To study the role of CerS2 in ceramide metabolism and cellular homoeostasis, we down-regulated CerS2 using siRNA (small interfering RNA) and examined several aspects of sphingolipid metabolism and cell stress responses. CerS2 down-regulation had a broad effect on ceramide homoeostasis, not just on VLC ceramides. Surprisingly, CerS2 down-regulation resulted in significantly increased LC (long-chain) ceramides, e.g. C(14), C(16), and our results suggested that the increase was due to a ceramide synthase-independent mechanism. CerS2-down-regulation-induced LC ceramide accumulation resulted in growth arrest which was not accompanied by apoptotic cell death. Instead, cells remained viable, showing induction of autophagy and activation of PERK [PKR (double-stranded-RNA-dependent protein kinase)-like endoplasmic reticulum kinase] and IRE1 (inositol-requiring 1) pathways [the latter indicating activation of the UPR (unfolded protein response)].

In addition to direct antitumor effects, proteasome inhibition also exerts strong effects on nonneoplastic immune cells. This indicates that proteasome inhibition, through the use of agents like bortezomib, could be used therapeutically to modulate immune responses. In this review we explore the emerging data, both preclinical and clinical, highlighting the importance of proteasome targeting of immunologic responses, primarily in the context of allogeneic hematopoietic stem cell transplantation (HSCT), both for the control of transplant-related toxicities like acute and chronic graft-versus-host disease (aGVHD, cGHVHD), and for improved malignant disease control after allogeneic HSCT Biol Blood Marrow Transplant 15: 1502-1512 (2009) (C) 2009 American Society for Blood and Marrow Transplantation C1 [Murphy, William J.; Welniak, Lisbeth A.] Univ Calif, Dept Dermatol, Davis Sch Med, Sacramento, CA 95818 USA.

To evaluate the role of race and SES, we studied 6207 unrelated-donor myeloablative (MA) HCT recipients transplanted between 1995 and 2004 for acute or chronic leukemia or myelodysplastic syndrome (MDS). Patients were reported by transplant center to be White (n = 5253), African American (n = 368), Asian/Pacific-Islander (n = 14 1), or Hispanic (n = 445). Patient income was estimated from residential zip code at time of HCT Cox regression analysis adjusting for other significant factors showed that African American (but not Asian or Hispanic) recipients had worse overall survival (OS) (relative-risk [RR] 1.47; 95% confidence interval [Cl] 1.29-1.68, P < .001) compared to Whites. Treatment-related mortality (TRM) was higher in African Americans (RR 1.56; 95% Cl 1.34-1.83, P < .001) and in Hispanics (RR 1.30; 95% CI 1.11-1.51, P = .001). Across all racial groups, patients with median incomes in the lowest quartile (<$34,700) had worse OS (RR 1.15; 95% Cl 1.04-1.26, P = .005) and higher risks of TRM (RR 1.21; 1.07-1.36, P = .002). Inferior outcomes among African Americans are not fully explained by transplant-related factors or SES. Potential other mechanisms such as genetic polymorphisms that have an impact on drug metabolism or unmeasured comorbidities, socioeconomic factors, and health behaviors may be important. Low SES, regardless of race, has a negative impact on unrelated donor HCT outcomes.

In the present report we propose to define conditioning regimens in 3 categories: (1) myeloablative (MA) conditioning, (2) reduced-intensity conditioning (RIC), and (3) nonmyeloablative (NMA) conditioning. Assignment to these categories is based on the duration of cytopenia and on the requirement for stem cell (SC) support: MA regimens cause irreversible cytopenia and SC support is mandatory. NMA regimens cause minimal cytopenia, and can be given also without SC support. RIC regimens do not fit criteria for MA or NMA regimens: they cause cytopenia of variable duration, and should be given with stem cell support, although cytopenia may not be irreversible. This report also assigns commonly used regimens to one of these categories, based upon the agents, dose, or combinations. Standardized classification of conditioning regimen intensities will allow comparison across studies and interpretation of study results.

TI Blood Stem Cell Transplantation in Older Patients SO BIOLOGY OF BLOOD AND MARROW TRANSPLANTATION LA English DT Article AB A serious dichotomy currently exists in hematopoietic stem cell transplantation (HSCT) and cancer research. Cancer is a disease that predominantly affects older people, yet there is a paucity of cancer research addressing the very unique needs of this population. Even basic biologic processes that exist in aging (decline in immune competency, increased sensitivities to therapies, etc.) are only beginning to be understood. Proportionally, the vast majority of cancer preclinical research does not involve the use of aged animals due to expense and time. This seriously hampers realistic extrapolation of preclinical findings to the general population affected by cancer. This report recommends research priorities that can help close the gaps in our understanding of aging as it relates to HSCT and cancer.

Here we develop a new fabrication method that allows for rapid, homogenous microencapsulation of insulin-secreting cells with varying microscale geometries and asymmetrically modified surfaces. Micromolding systems were developed using polypropylene mesh, and the material/surface properties associated with efficient encapsulation were identified. Cells encapsulated using these methods maintain desirable viability and preserve their ability to proliferate and secrete insulin in a glucose-responsive manner. This new cell encapsulation approach enables a practical route to an inexpensive and convenient process for the generation of cell-laden microcapsules without requiring any specialized equipment or microfabrication process.

Assuming an accelerated failure time (AFT) model with unspecified error distribution for the time to the event of interest, we propose rank-based estimating equations for the model parameters and use a generalization of the EM algorithm for parameter estimation. Applying our proposed AFT model to the same motivating breast cancer dataset as Dahlberg and Wang (Biometrics 2007, 63, 1237-1244), our results are more intuitive for the treatment arm in which the PH assumption may be violated. We also conduct a simulation study to evaluate the performance of the proposed method. C1 [Zhang, Jenny J.; Wang, Molin] Harvard Univ, Sch Publ Hlth, Dept Biostat, Boston, MA 02115 USA.

TI A Latent Class Model with Hidden Markov Dependence for Array CGH Data SO BIOMETRICS LA English DT Article DE Array CGH; Hidden Markov Model; Latent class ID COMPARATIVE GENOMIC HYBRIDIZATION; DNA MICROARRAY DATA; BREAST-CANCER; LINEAR-MODELS; PREDICTORS AB P>Array CGH is a high-throughput technique designed to detect genomic alterations linked to the development and progression of cancer. The technique yields fluorescence ratios that characterize DNA copy number change in tumor versus healthy cells. Classification of tumors based on aCGH profiles is of scientific interest but the analysis of these data is complicated by the large number of highly correlated measures. In this article, we develop a supervised Bayesian latent class approach for classification that relies on a hidden Markov model to account for the dependence in the intensity ratios. Supervision means that classification is guided by a clinical endpoint. Posterior inferences are made about class-specific copy number gains and losses. We demonstrate our technique on a study of brain tumors, for which our approach is capable of identifying subsets of tumors with different genomic profiles, and differentiates classes by survival much better than unsupervised methods.

These studies make the implicit assumption of stability of symptoms across episodes in mood disorders, which has rarely been investigated. Methods: We examined prospective data from a cohort of 3,750 individuals with bipolar I or II disorder participating in the Systematic Treatment Enhancement Program for Bipolar Disorder study, selecting a subset of individuals who experienced two depressive episodes during up to two years of follow-up. Across-episode association of individual depressive or hypomanic/mixed symptoms was examined using the weighted kappa measure of agreement as well as logistic regression. Results: A total of 583 subjects experienced two prospectively observed depressive episodes, with 149 of those subjects experiencing a third. Greatest evidence of stability was observed for neurovegetative features, suicidality, and guilt/rumination. Loss of interest and fatigue were not consistent across episodes. Structural equation modeling suggested that the dimensional structure of symptoms was not invariant across episodes. Conclusion: While the overall dimensional structure of depressive symptoms lacks temporal stability, individual symptoms including suicidality, mood, psychomotor, and neurovegetative symptoms are stable across major depressive episodes in bipolar disorder and should be considered in future investigations of course and pathophysiology in bipolar disorder.

Defibrotide is a polydisperse oligonucleotide with antithrombotic, profibrinolytic, anti-ischemic, and antiadhesive properties. Numerous clinical studies have shown promising activity of defibrotide in the treatment and prevention of veto-occlusive disease, with minimal toxicity. In corollary laboratory studies, defibrotide has been shown to decrease plasminogen activator inhibitor-1, increase tissue plasminogen activator levels, and increase overall plasma fibrinolytic activity in patients. Plasmin, a potent and nonspecific serine protease, plays a pivotal role in fibrinolysis by virtue of its ability to effectively degrade fibrin clots. In this study, defibrotide increases the activity of plasmin in hydrolyzing its substrate in a dose-dependent and length-dependent manner. Similar concentration-dependent effects of defibrotide were observed when plasmin was generated by tissue plasminogen activator or urokinase activation of plasminogen. In contrast, defibrotide had no direct effect on the activation of plasminogen to plasmin. Defibrotide was also able to enhance the activity of plasmin in degrading fibrin clot formed from fibrinogen, plasminogen, and thrombin. This effect was also concentration-dependent and directly correlated with the enzymatic activity of plasmin. This study therefore demonstrates that defibrotide is capable of enhancing the activity of plasmin and so contributes to its fibrinolytic activity. Taken together, these results support the effect of defibrotide in restoring the fibrinolytic vascular phenotype, in microangiopathic conditions such as veto-occlusive disease.

Circulating FGF-23 levels are increased in patients with chronic kidney disease (CKD); however, FGF-23 skeletal expression and its regulation by DMP1 and MEPE have yet to be evaluated. Thus. expression of these three proteins was characterized by immunohistochemistry in 32 pediatric and young adult patients with CKD stages 2-5. When compared to normal controls, bone FGF-23 and DMP1 expression were increased in all stages of CKD; significant differences in bone FGF-23 and DMP1 expression were not detected between pre-dialysis CKD and dialysis patients. Bone MEPE expression in CKD did not differ from controls. FGF-23 was expressed in osteocyte cell bodies located at the trabecular periphery. DMP1 was widely expressed in osteocyte cell bodies and dendrites throughout bone. MEPE was also expressed throughout bone, but only in osteocyte cell bodies. Bone FGF-23 expression correlated directly with plasma levels of the protein (r=0.43, p<0.01) and with bone DMP1 expression (r=0.54, p<0.01) and expression of both proteins were inversely related to osteoid accumulation. Bone MEPE expression was inversely related to bone volume. In conclusion, skeletal FGF-23 and DMP1 expression are increased in CKD and are related to skeletal mineralization. The patterns of expression of FGF-23, MEPE, and DMP1 differ markedly in trabecular bone, suggesting that individual osteocytes may have specialized functions. Increases in bone FGF-23 and DMP1 expression suggest that osteocyte function is altered early in the course of CKD. (C) 2009 Elsevier Inc. All rights reserved.

After 96-h drug exposure, several multiple myeloma (MM) cell lines were more sensitive to VE465 compared to non-malignant cells. The anti-MM activity of VE465 was maintained in the presence of interleukin-6 and, interestingly, enhanced by co-culture with stromal cells. However, primary MM cells were less responsive than cell lines. Combinations with dexamethasone (Dex), doxorubicin (Doxo) and bortezomib showed no antagonism. Our study highlights the potential role of the tumour microenvironment in modulating the activity of this drug class.

TI Clinical value of minor responses after 4 doses of rituximab in Waldenstrom macroglobulinaemia: a follow-up of the Eastern Cooperative Oncology Group E3A98 trial SO BRITISH JOURNAL OF HAEMATOLOGY LA English DT Article DE lymphoplasmacytic lymphoma; monoclonal IgM protein; rituximab; Waldenstrom macroglobulinaemia ID CONSENSUS PANEL RECOMMENDATIONS; 3RD INTERNATIONAL WORKSHOP; PROGNOSTIC-FACTORS; UPDATE; THERAPY AB P>Waldenstrom macroglobulinaemia is a low-grade, lymphoplasmacytic lymphoma that is responsive to rituximab. We report the role of a minor response in predicting overall outcomes. We extended follow-up of a previously described cohort (n = 69) treated with 4 weekly doses of rituximab and observed durable responses (median time to progression, 30 months; 5-year survival rate, 66%). Patients achieving a minor response [25-50% immunoglobulin M (IgM) reduction] appeared to do as well as those achieving an objective response (> 50% IgM reduction), which suggests that more aggressive or intensive therapy for minor responders is not required. Future studies of Waldenstrom macroglobulinaemia should report minor responses because they are associated with clinically meaningful benefits. This trial was registered at http://www.clinicaltrials.gov as #NCT00005609. C1 [Gertz, Morie A.; Greipp, Philip R.; Rajkumar, S. V.] Mayo Clin, Div Hematol, Rochester, MN 55905 USA.

It has always been a reliable and specific cytochemical marker for hairy cell leukemia and for differentiated cells of monocytic lineage. Only recently has the test for serum TRAP activity been accepted as sensitive and specific enough for clinical use as a marker of osteoclasts and bone resorption. This has come about through steady advances in knowledge about TRAP enzymology, structure, function, and molecular regulation and a consequent appreciation that TRAP isoforms 5a and 5b have very different clinical significance. As a measure of osteoclast number and bone resorption, TRAP 5b has diagnostic and prognostic applications in osteoporosis, cancers with bone metastasis, chronic renal failure, and perhaps other metabolic and pathologic bone diseases. Serum TRAP 5a, on the other hand, has no relationship to bone metabolism but seems instead to be a measure of activated macrophages and chronic inflammation. Exploration of the real clinical usefulness of serum TRAP 5a for diagnosis and disease management in a wide variety of chronic inflammatory diseases is only now beginning. This perspective traces the important basic scientific developments that have led up to the refinement of serum TRAP isoform immunoassays and their validation as biomarkers of disease. Many unanswered questions remain, providing a wealth of opportunity for continued research of this multifaceted enzyme.

This variability likely stems from epigenetic and genetic influences, either stochastic or hardwired by cell type-specific lineage programs. That differentiation underlies tumor cell heterogeneity was elegantly demonstrated in hematopoietic tumors, in which rare primitive cells (cancer stem cells (CSCs)) resembling normal hematopoietic stem cells are ultimately responsible for tumor growth and viability. Because of the compelling clinical implications CSCs pose-across the entire spectrum of cancers-investigators applied the CSC model to cancers arising in tissues with crudely understood differentiation programs. Instead of relying on differentiation, these studies used empirically selected markers and statistical arguments to identify CSCs. The empirical approach has stimulated important questions about "stemness" in cancer cells as well as the validity and stoichiometry of CSC assays. The recent identification of urothelial differentiation programs in urothelial carcinomas (UroCas) supports the idea that solid epithelial cancers (carcinomas) develop and differentiate analogously to normal epithelia and provides new insights about the spatial localization and molecular makeup of carcinoma CSCs. Importantly, CSCs from invasive UroCas (UroCSCs) appear well situated to exchange important signals with adjacent stroma, to escape immune surveillance, and to survive cytotoxic therapy. These signals have potential roles in treatment resistance and many participate in druggable cellular pathways. In this review, we discuss the implications of these findings in understanding CSCs and in better understanding how UroCas form, progress, and should be treated.

Herein we identify the human respiratory syncytial virus (RSV) as an oncolytic virus. Using prostate cancer models, we show dramatic enhancement of RSV infectivity in vitro in the androgen-independent, highly metastatic PC-3 human prostate cancer cells compared to the non-tumorigenic RWPE-1 human prostate cells. The oncolytic efficiency of RSV was established in vivo using human prostate tumor xenografts in nude mice. Intratumoral and intraperitoneal injections of RSV led to a significant regression of prostate tumors. Furthermore, enhanced viral burden in PC-3 cells led to selective destruction of PC-3 cancer cells in vitro and in xenograft tumors in vivo due to apoptosis triggered by the downregulation of nuclear factor-kappa B (NF-kappa B) activity (and the resulting loss of anti-apoptotic function of NF-kappa B) in RSV-infected PC-3 cells. The intrinsic (mitochondrial) pathway constitutes the major apoptotic pathway; however, the death-receptor-dependent extrinsic pathway, mediated by the paracrine/autocrine action of tumor necrosis factor-alpha produced from infected cells, also partly contributed to apoptosis. Thus, the oncolytic property of RSV can potentially be exploited to develop targeted therapeutics for the clinical management of prostate tumors.

The underlying transcriptional program(s) that regulate this phenotypic change is largely unknown. To identify molecular determinants of this process, we performed a Bayesian-based dynamic gene expression analysis on primary melanocytes undergoing proliferative arrest. This analysis revealed several related clusters whose expression behavior correlated with the melanocyte growth kinetics; we designated these clusters the melanocyte growth arrest program (MGAP). These MGAP genes were preferentially represented in benign melanocytic nevi over melanomas and selectively mapped to the hepatocyte fibrosis pathway. This transcriptional relationship between melanocyte growth stasis, nevus biology, and fibrogenic signaling was further validated in vivo by the demonstration of strong pericellular collagen deposition within benign nevi but not melanomas. Taken together, our study provides a novel view of fibroplasia in both melanocyte biology and nevogenesis.

MR-tracked navigation was performed to the left atrium (LA) and atrioventricular (AV) node, followed by LA electroanatomic mapping and radiofrequency ablation of the pulmonary veins (PVs) and AV node. Methods and Results-One ventricular ablation, 7 PV ablations, 3 LA mappings, and 3 AV node ablations were conducted. Three MRI-compatible devices (ablation/mapping catheter, torqueable sheath, stimulation/pacing catheter) were used, each with 4 to 5 tracking microcoils. Transseptal puncture was performed under x-ray, with all other procedural steps performed in the MRI. Preacquired MRI roadmaps served for real-time catheter navigation. Simultaneous tracking of 3 devices was performed at 13 frames per second. LA mapping and PV radiofrequency ablation were performed using tracked ablation catheters and sheaths. Ablation points were registered and verified after ablation using 3D myocardial delayed enhancement and postmortem gross tissue examination. Complete LA electroanatomic mapping was achieved in 3 of 3 pigs, Right inferior PV circumferential ablation was achieved in 3 of 7 pigs, with incomplete isolation caused by limited catheter deflection. During AV node ablation, ventricular pacing was performed, 3 devices were simultaneously tracked, and intracardiac ECGs were displayed. 3D myocardial delayed enhancement visualized node injury 2 minutes after ablation. AV node block succeeded in 2 of 3 pigs, with 1 temporary block. Conclusions-LA mapping, PV radiofrequency ablation, and AV node ablation were demonstrated under MRI guidance. Intraprocedural 3D myocardial delayed enhancement assessed lesion positional accuracy and dimensions. (Circ Arrhythm Electrophysiol. 2009; 2: 695-704.)

Experimental Design: We examined the growth inhibitory effect of 1339 against multiple myeloma cell lines in the absence and in the presence of bone marrow stromal cells, alone or in combination with dexamethasone, bortezomib, perifosine, and Revlimid. Using the severe combined immunodeficient (SCID)-hu murine model of multiple myeloma, we also examined the effect of 1339 on multiple myeloma cell growth and multiple myeloma bone disease. Results: mAb 1339 significantly inhibited growth of multiple myeloma cell in the presence of bone marrow stromal cell in vitro, associated with inhibition of phosphorylation of signal transducer and activator of transcription 3, extracellular signal-regulated kinase 1/2, and Akt. In addition, mAb 1339 enhanced cytotoxicity induced by dexamethasone, as well as bortezomib, lenalidomide, and perifosine, in a synergistic fashion. Importantly mAb 1339 significantly enhanced growth inhibitory effects of dexamethasone in vivo in SCID-hu mouse model of multiple myeloma. mAb 1339 treatment also resulted in inhibition of osteoclastogenesis in vitro and bone remodeling in SCID-hu model. Conclusions: Our data confirm in vitro and in vivo anti-multiple myeloma activity of, as well as inhibition of bone turnover by, fully humanized mAb 1339, as a single agent and in combination with conventional and novel agents, providing a rationale for its clinical evaluation in multiple myeloma.

Mitsiades, Nicholas TI Interactions of the Hdm2/p53 and Proteasome Pathways May Enhance the Antitumor Activity of Bortezomib SO CLINICAL CANCER RESEARCH LA English DT Article ID MULTIPLE-MYELOMA CELLS; INHIBITOR PS-341; ANTIMYELOMA ACTIVITY; P53 PATHWAY; CANCER; APOPTOSIS; GENE; MDM2; SENSITIVITY; ANTAGONISTS AB Purpose: p53 is inactivated in many human malignancies through missense mutations or overexpression of the human homologue of Mdm2 (Hdm2), an E3 ubiquitin ligase that ubiquitinates p53, thereby promoting its proteasomal degradation. The cis-imidazoline nutlin-3 can disrupt the p53-Hdm2 interaction and activate p53, inducing apoptosis in vitro in many malignancies, including multiple myeloma (MM). Experimental Design: We hypothesized that suppression of Hdm2-mediated p53 ubiquitination may augment sequelae of p53 accumulation caused by proteasomal inhibition. We compared the response of MM cells versus several epithelial cancer models to the proteasome inhibitor bortezomib in combination with nutlin-3. Results: The combination of sublethal concentrations of bortezomib plus nutlin-3 induced additive cytotoxicity against bortezomib-sensitive MM cell lines. Importantly, however, in breast, prostate, colon, and thyroid (papillary, follicular, anaplastic, and medullary) carcinoma cell lines, this combination triggered synergistic cytotoxicity, and increased expression of p53, p21, Hdm2, Bax, Noxa, PUMA, and cleavage of caspase-3 and poly ADP ribose polymerase. Coculture with bone marrow stromal cells attenuated MM cell sensitivity to nutlin-3 monotherapy and was associated with evidence of suppression of p53 activity in MM cells, whereas combined bortezomib-nutlin-3 treatment maintained cytotoxicity even in the presence of bone marrow stromal cells. Conclusions: This differential response of MM versus epithelial carcinomas to combination of nutlin-3 with bortezomib sheds new light on the role of p53 in bortezomib-induced apoptosis. Concurrent Hdm2 inhibition with bortezomib may extend the spectrum of bortezomib applications to malignancies with currently limited sensitivity to single-agent bortezomib or, in the future, to MM patients with decreased clinical responsiveness to bortezomib-based therapy.

TI High-Throughput Screening Identifies Two Classes of Antibiotics as Radioprotectors: Tetracyclines and Fluoroquinolones SO CLINICAL CANCER RESEARCH LA English DT Article ID HISTONE ACETYLTRANSFERASE; EXTRACELLULAR ADENOSINE; IONIZING-RADIATION; TUMOR-CELLS; MICE; ACETYLATION; DAMAGE; CHROMATIN; REPAIR; TIP60 AB Purpose: Discovery of agents that protect or mitigate normal tissue from radiation injury during radiotherapy, accidents, or terrorist attacks is of importance. Specifically, bone marrow insufficiency, with possible infection due to immunosuppression, can occur after total body irradiation (TBI) or regional irradiation and is a major component of the acute radiation syndrome. The purpose of this study was to identify novel radioprotectors and mitigators of the hematopoietic system. Experimental Design: High-throughput screening of small-molecule libraries was done using viability of a murine lymphocyte line as a readout with further validation in human lymphoblastoid cells. The selected compounds were then tested for their ability to counter TBI lethality in mice. Results: All of two major classes of antibiotics, tetracyclines and fluoroquinolones, which share a common planar ring moiety, were radioprotective. Furthermore, tetracycline protected murine hematopoietic stem/progenitor cell populations from radiation damage and allowed 87.5% of mice to survive when given before and 35% when given 24 h after lethal TBI. Interestingly, tetracycline did not alter the radiosensitivity of Lewis lung cancer cells. Tetracycline and ciprofloxacine also protected human lymphoblastoid cells, reducing radiation-induced DNA double-strand breaks by 33% and 21%, respectively. The effects of these agents on radiation lethality are not due to the classic mechanism of free radical scavenging but potentially through activation of the Tip60 histone acetyltransferase and altered chromatin structure. Conclusions: Tetracyclines and fluoroquinolones can be robust radioprotectors and mitigators of the hematopoietic system with potential utility in anticancer radiotherapy and radiation emergencies.

KRAS mutation in metastatic colorectal cancer predicts resistance to anti-epidermal growth factor receptor (EGFR)-targeted therapy (cetuximab or panitumumab). It remains uncertain, however, whether KRAS mutation predicts prognosis or clinical outcome of colon cancer patients independent of anti-EGFR therapy. Methods: We conducted a study of 508 cases identified among 1,264 patients with stage III colon cancer who enrolled in a randomized adjuvant chemotherapy trial (5-fluorouracil, leucovorin with or without irinotecan) in 1999-2001 (CALGB 89803). KRAS mutations were detected in 178 tumors (35%) by pyrosequencing. Kaplan-Meier and Cox proportional hazard models assessed the prognostic significance of KRAS mutation and adjusted for potential confounders including age, sex, tumor location, tumor/node stage, performance status, adjuvant chemotherapy arm, and microsatellite instability status. Results: Compared with patients with KRAS-wild-type tumors, patients with KRAS-mutated tumors did not experience any difference in disease-free, recurrence-free, or overall survival. The 5-year disease-free, recurrence-free, and overall survival rates (KRAS-mutated versus KRAS-wild-type patients) were 62% versus 63% (log-rank P = 0.89), 64% versus 66% (P = 0.84), and 75% versus 73% (P = 0.56), respectively. The effect of KRAS mutation on patient survival did not significantly differ according to clinical features, chemotherapy arm, or microsatellite instability status, and the effect of adjuvant chemotherapy assignment on outcome did not differ according to KRAS status. Conclusions: In this large trial of chemotherapy in stage III colon cancer patients, KRAS mutational status was not associated with any significant influence on disease-free or overall survival.

Stephen TI Guidelines for the Evaluation of Immune Therapy Activity in Solid Tumors: Immune-Related Response Criteria SO CLINICAL CANCER RESEARCH LA English DT Article ID LYMPHOCYTE-ASSOCIATED ANTIGEN-4; METASTATIC MELANOMA; PHASE-I/II; 2 CYCLES; CANCER; IPILIMUMAB; BLOCKADE; AUTOIMMUNITY; CHEMOTHERAPY; REGRESSION AB Purpose: Immunotherapeutic agents produce antitumor effects by inducing cancer-specific immune responses or by modifying native immune processes. Resulting clinical response patterns extend beyond those of cytotoxic agents and can manifest after an initial increase in tumor burden or the appearance of new lesions (progressive disease). Response Evaluation Criteria in Solid Tumors or WHO criteria, designed to detect early effects of cytotoxic agents, may not provide a complete assessment of immunotherapeutic agents. Novel criteria for the evaluation of antitumor responses with immunotherapeutic agents are required. Experimental Design: The phase II clinical trial program with ipilimumab, an antibody that blocks CTL antigen-4, represents the most comprehensive data set available to date for an immunotherapeutic agent. Novel immune therapy response criteria proposed, based on the shared experience from community workshops and several investigators, were evaluated using data from ipilimumab phase II clinical trials in patients with advanced melanoma. Results: Ipilimumab monotherapy resulted in four distinct response patterns: (a) shrinkage in baseline lesions, without new lesions; (b) durable stable disease (in some patients followed by a slow, steady decline in total tumor burden); (c) response after an increase in total tumor burden; and (d) response in the presence of new lesions. All patterns were associated with favorable survival. Conclusion: Systematic criteria, designated immune-related response criteria, were defined in an attempt to capture additional response patterns observed with immune therapy in advanced melanoma beyond those described by Response Evaluation Criteria in Solid Tumors or WHO criteria. Further prospective evaluations of the immune-related response criteria, particularly their association with overall survival, are warranted.

TI Increases of Cardiac Troponin in Conditions other than Acute Coronary Syndrome and Heart Failure SO CLINICAL CHEMISTRY LA English DT Review ID ACUTE AORTIC DISSECTION; CRITICALLY-ILL PATIENTS; RADIOFREQUENCY CATHETER ABLATION; ACUTE MYOCARDIAL-INFARCTION; ACUTE ISCHEMIC-STROKE; ASSOCIATION STATISTICS-COMMITTEE; RESPIRATORY-DISTRESS-SYNDROME; ACUTE ALLOGRAFT-REJECTION; ACUTE PULMONARY-EMBOLISM; INTENSIVE-CARE-UNIT AB BACKGROUND: Although cardiac troponin (cTn) is a cornerstone marker in the assessment and management of patients with acute coronary syndrome (ACS) and heart failure (HF), cTn is not diagnostically specific for any single myocardial disease process. This narrative review discusses increases in cTn that result from acute and chronic diseases, iatrogenic causes, and myocardial injury other than ACS and HF. CONTENT: Increased cTn concentrations have been reported in cardiac, vascular, and respiratory disease and in association with infectious processes. In cases involving acute aortic dissection, cerebrovascular accident, treatment in an intensive care unit, and upper gastrointestinal bleeding, increased cTn predicts a longer time to diagnosis and treatment, increased length of hospital stay, and increased mortality. cTn increases are diagnostically and prognostically useful in patients with cardiac inflammatory diseases and in patients with respiratory disease; in respiratory disease cTn can help identify patients who would benefit from aggressive management. In chronic renal failure patients the diagnostic sensitivity of cTn for ACS is decreased, but cTn is prognostic for the development of cardiovascular disease. cTn also provides useful information when increases are attributable to various iatrogenic causes and blunt chest trauma. SUMMARY: Information on the diagnostic and prognostic uses of cTn in conditions other than ACS and heart failure is accumulating. Although increased cTn in settings other than ACS or heart failure is frequently considered a clinical confounder, the astute physician must be able to interpret cTn as a dynamic marker of myocardial damage, using clinical acumen to determine the source and significance of any reported cTn increase.

COLD-PCR (coamplification at lower denaturation temperature-PCR) is a new form of PCR that enriches mutation-containing amplicons to concentrations sufficient for direct sequencing; nevertheless, sequencing itself remains an expensive mutation-screening approach. Conversely, high-resolution melting (HRM) is a rapid, inexpensive scanning method, but it cannot specifically identify the detected mutation. To enable enrichment, quick scanning, and identification Of low-level unknown mutations, we combined COLD-PCR with HRM mutation scanning, followed by sequencing of positive samples. METHODS: Mutation-containing cell-line DNA serially diluted into wild-type DNA and DNA samples from human lung adenocarcinomas containing low-level mutations were amplified via COLD-PCR and via conventional PCR for TP53 (tumor protein p53) exons 6-8, and the 2 approaches were compared. HRM analysis was used to screen amplicons for mutations; mutation-positive amplicons were sequenced. RESULTS: Dilution experiments indicated an approximate 6- to 20-fold improvement in selectivity with COLD-PCR/HRM. Conventional PCR/HRM exhibited mutation-detection limits of approximately 2% to 10%, whereas COLD-PCR/HRM exhibited limits from approximately 0.1% to 1% mutant-to-wild-type ratio. After HRM analysis of lung adenocarcinoma samples, we detected 7 mutations by both PCR methods in exon 7; however, in exon 8 we detected 9 mutations in COLD-PCR amplicons, compared with only 6 mutations in conventional-PCR amplicons. Furthermore, 94% of the HRM-detected mutations were successfully sequenced with COLD-PCR amplicons, compared with 50% with conventional-PCR amplicons. CONCLUSIONS: COLD-PCR/HRM improves the mutation-scanning capabilities of HRM and combines high selectivity, convenience, and low cost with the ability to sequence unknown low-level mutations in clinical samples.

The purpose of this study was to investigate relationships of GH to metabolic and anthropometric parameters in HIV patients and non-HIV controls. Design Peak GH and metabolic parameters were assessed in a cross-sectional study of 191 HIV patients and 62 age and BMI-matched healthy controls. Methods Peak GH was assessed by GHRH/arginine stimulation testing. Results HIV patients demonstrated similar BMI, but increased waist circumference (WC) and reduced peak GH to GHRH/arginine compared with control subjects [median = 12 center dot 4 (interquartile range: 6 center dot 3-24 center dot 8) vs. 21 center dot 3 (8 center dot 8, 34 center dot 5) mu g/l, P = 0 center dot 006, HIV vs. control]. Among HIV and non-HIV groups, peak GH was inversely associated with WC (rho = -0 center dot 44, P < 0 center dot 0001; rho = -0 center dot 63, P < 0 center dot 0001; HIV patients and controls, respectively), blood pressure (rho = -0 center dot 17, P = 0 center dot 02; rho = -0 center dot 36, P = 0 center dot 004), triglycerides (rho = -0 center dot 37, P < 0 center dot 0001; rho = -0 center dot 43, P = 0 center dot 001), glucose (rho = -0 center dot 34, P < 0 center dot 0001; rho = -0 center dot 30, P = 0 center dot 02), insulin (rho = -0 center dot 43, P < 0 center dot 0001; rho = -0 center dot 60, P < 0 center dot 0001) and CRP (rho = -0 center dot 29, P < 0 center dot 0001; rho = -0 center dot 59, P < 0 center dot 0001). Among HIV patients, the inverse association between peak GH and fasting glucose remained significant (beta = -0 center dot 006 mmol/l change in glucose per mu g/l change in GH, P = 0 center dot 004) controlling for age, gender, race, BMI, WC, protease inhibitor (PI) and nucleoside reverse transcriptase inhibitors. Similarly, the inverse association between peak GH and triglycerides remained significant (beta = -0 center dot 01 mmol/l change in triglycerides per mu g/l change in GH, P = 0 center dot 02) controlling for age, gender, race, BMI, WC, PI and lipid-lowering medications. HIV men with peak GH < 7 center dot 5 mu g/l demonstrated higher BMI, WC, SBP, triglycerides, glucose and CRP. Conclusions Reduced GH secretion is independently associated with dyslipidaemia and higher glucose, among HIV patients with abdominal fat accumulation.

Our objective was to estimate treatment response and its predictors and describe current referral practices for 131I therapy. Design Retrospective study. Patients One hundred and thirty-one children 30 days-21 years old with laboratory evidence of hyperthyroidism, seen in an academic paediatric and adolescent endocrinology practice. Measurements Rate of referral, indications for 131I, predictors of poor treatment response. Results Thirty-eight of 102 patients with persistent hyperthyroidism (37%) received 131I (160 mu Ci/g thyroid tissue/131I uptake), as did an additional 10 patients initially evaluated by adult thyroidologists. Primary indications were intolerance to (29%) or poor control on (19%) antithyroid drugs, patient preference (50%) and unknown (2%). Of 48 patients treated with 131I, 89% and 11% became hypothyroid after one and two 131I doses, respectively. The goal of 131I therapy was attainment of hypothyroidism. 'Poor treatment response' (seen in 27%) was defined as requirement for a second 131I dose or failure to achieve hypothyroidism after 6 months. Predictors of poor treatment response included: previous use of antithyroid drugs (37%vs. 0%, P = 0 center dot 02), ophthalmopathy (58%vs. 8%, P = 0 center dot 002), and an interval of >= 12 months from diagnosis to 131I (50%vs. 10%, P = 0 center dot 003). A very elevated free T4 tended to be more prevalent in those with poor response. Conclusions In children and adolescents with hyperthyroidism, high rates of success after 131I are achievable. Use of antithyroid drugs, pre-existing eye disease and prolonged time to 131I may confer relative resistance to 131I.

Clinical presentation of PCFT deficiency may mimic severe combined immune deficiency (SCID). We report a 4-month-old female who presented with failure to thrive, normocytic anemia, Pneumocystis jirovecii pneumonia and systemic cytomegalovirus infection. Immunological evaluation revealed hypogammaglobulinemia, absent antibody responses, and tack of mitogen-induced lymphocyte proliferative responses. However, the absolute number and distribution of lymphocyte subsets, including naive T cells and recent thymic emigrants, were normal, arguing against primary SCID. Serum and cerebrospinal fluid folate levels were undetectable. A homozygous 1082-1G>A mutation of the PCFT gene was found, resulting in skipping of exon 3. Parenteral folinic acid repletion resulted in normalization of anemia, humoral and cellular immunity, and full clinical recovery. PCFT mutations should be considered in infants with SCID-like phenotype, as the immunodeficiency is reversible with parenteral. folinic acid repletion. (C) 2009 Elsevier Inc. All rights reserved.

TI Diagnostic Performance of the (1 -> 3)-beta-D-Glucan Assay for Invasive Fungal Disease SO CLINICAL INFECTIOUS DISEASES LA English DT Article ID BETA-D-GLUCAN; GALACTOMANNAN ENZYME-IMMUNOASSAY; CIRCULATING GALACTOMANNAN; TRANSPLANT RECIPIENTS; CELL TRANSPLANTATION; NEUTROPENIC PATIENTS; REACTIVE MATERIAL; MEMBRANE FILTERS; LIMULUS TEST; INFECTIONS AB Background. Diagnosis of invasive fungal disease (IFD) is challenging, and it remains a significant cause of morbidity and mortality in immunocompromised patients. The (1 -> 3)-beta-D-glucan (BG) assay may be a useful adjunct, but its diagnostic performance is not well characterized. Methods. We retrospectively assessed the diagnostic indices of the BG assay in patients at risk of IFD who had a compatible clinical syndrome for the diagnosis of IFD a week after initial BG testing and at the end of the hospitalization associated with the first BG value. Patients with IFD were classified according to current European Organization for Research and Treatment of Cancer-Mycoses Study Group criteria, independent of BG results. Results. A total of 1308 BG assays were performed for 871 patients. One hundred twelve proven or probable IFD cases were diagnosed within 1 week after initial testing, and 116 cases were diagnosed by the end of hospitalization. Sensitivity of an initial BG level >= 80 pg/mL for IFD at 1 week was 0.64 (95% confidence interval [CI], 0.55-0.73), specificity was 0.84 (95% CI, 0.81-0.86), the positive likelihood ratio was 3.93 (95% CI, 2.94-5.26), and the negative likelihood ratio was 0.43 (95% CI, 0.31-0.59). Albumin, intravenous immunoglobulin, and hemodialysis were associated with elevated BG levels in patients without IFD (odds ratio, 4.78; 95% CI, 2.59-8.80). After excluding patients with these factors, specificity and the positive likelihood ratio of an initial BG level >= 80 pg/mL increased slightly. Empirical systemic antifungal treatment did not reduce overall BG sensitivity. Sensitivity was slightly lower among patients with hematologic malignancy or stem cell transplantation. Consideration of BG results would have increased the diagnostic certainty to probable in 54% of possible IFD cases. Conclusions. BG level appears to be a fair diagnostic adjunct for IFD in patients with appropriate pretest probability and a suggestive clinical syndrome, especially when checked serially in patients not receiving factors associated with an elevated BG level in the absence of IFD.

Whether outcome of central nervous system (CNS) cryptococcosis in solid organ transplant recipients treated with lipid formulations of amphotericin B is different from the outcome of the condition treated with amphotericin B deoxycholate (AmBd) is not known. Methods. We performed a multicenter study involving a cohort comprising consecutive solid organ transplant recipients with CNS cryptococcosis. Results. Of 75 patients treated with polyenes as induction regimens, 55 (73.3%) received lipid formulations of amphotericin B and 20 (26.7%) received AmBd. Similar proportions of patients in both groups had renal failure at baseline (P = .94). Overall, mortality at 90 days was 10.9% in the group that received lipid formulations of amphotericin B and 40.0% in the group that received AmBd. In univariate analysis, nonreceipt of calcineurin inhibitors (P = .034), renal failure at baseline (P = .016), and fungemia (P = .003) were significantly associated with mortality. Compared with AmBd, lipid formulations of amphotericin B were associated with a lower mortality (P = .007). Mortality did not differ between patients receiving lipid formulations of amphotericin B with or without flucytosine (P = .349). In stepwise logistic regression analysis, renal failure at baseline (odds ratio [OR], 4.61; 95% confidence interval [CI], 1.02-20.80; P = .047) and fungemia (OR, 10.66; 95% CI, 2.08-54.55; P = .004) were associated with an increased mortality, whereas lipid formulations of amphotericin B were associated with a lower mortality (OR, 0.11; 95% CI, 0.02-0.57; P = .008). Conclusions. Lipid formulations of amphotericin B were independently associated with better outcome and may be considered as the first-line treatment for CNS cryptococcosis in these patients.

The goals of testing are to detect possible drug resistance in common pathogens and to assure susceptibility to drugs of choice for particular infections. The most widely used testing methods include broth microdilution or rapid automated instrument methods that use commercially marketed materials and devices. Manual methods that provide flexibility and possible cost savings include the disk diffusion and gradient diffusion methods. Each method has strengths and weaknesses, including organisms that may be accurately tested by the method. Some methods provide quantitative results (eg, minimum inhibitory concentration), and all provide qualitative assessments using the categories susceptible, intermediate, or resistant. In general, current testing methods provide accurate detection of common antimicrobial resistance mechanisms. However, newer or emerging mechanisms of resistance require constant vigilance regarding the ability of each test method to accurately detect resistance.

Calcification of both coronary and extra-cardiac vessels is common in ESRD. Several studies suggest that vascular calcification is associated with coronary atherosclerosis, vascular wall stiffness, left ventricular hypertrophy, and subsequent increased mortality, but it is not yet clear if vascular calcification is a direct cause of these changes or merely a marker of disease. Reviewed here is the current state of research on the biology and the significance of vascular calcification in ESRD, the role of vitamin D therapy in its development, and options for management.

Only 1% to 4% of pregnancies are complicated by maternal cardiac disease and most of these can be managed with medical therapy and lifestyle changes. On occasion, whether owing to natural progression of the underlying cardiac disease or precipitated by the cardiovascular changes of pregnancy, cardiac surgical therapy must be considered. Cardiac surgery is inherently dangerous for both, the mother and fetus with mortality rates near 10% and 30%, respectively. For some conditions, percutaneous cardiac intervention offers effective therapy with far less risk to the mother and her fetus. For others, cardiac surgery, including procedures that mandate the use of cardiopulmonary bypass, must be entertained to save the life of the mother. Given the extreme risks to the fetus, if the patient is in the third trimester strong consideration should be given to deliver; before surgery involving cardiopulmonary bypass. At earlier gestational ages when this is not feasible, modifications to the perfusion protocol including higher flow rates, normothermic perfusion, pulsatile flow, and the use of intraoperative external fetal heart rate monitoring should be considered.

There has been significant controversy regarding healthcare policy for those service members and military veterans who returned from OEF/OIF deployments with both mild TBI and PTSD. There is currently little empirical evidence available to address these controversies. This review uses a cognitive neuroscience framework to address the potential impact of mild TBI on the development, course, and clinical management of PTSD. The field would benefit from research efforts that take into consideration the potential differential impact of mild TBI with versus without persistent cognitive deficits, longitudinal work examining the trajectory of PTSD symptoms when index trauma events involve TBI, randomized clinical trials designed to examine the impact of mild TBI on response to existing PTSD treatment interventions, and development and examination of potential treatment augmentation strategies.

While many of the mental health readjustment issues of female service members are likely to mirror those of the majority male Veteran population, this newest generation of women Veterans may also face unique threats to their mental health. The goal of this review it to highlight emerging issues relevant to the development of posttraumatic stress disorder (PTSD) among women deployed to Iraq and Afghanistan by reviewing the existing literature on gender-relevant issues among this cohort, as well as raising theoretically important issues that are worthy of further empirical investigation. Topics addressed include gender differences in combat experiences and in PTSD following combat exposure; sexual assault, sexual harassment and other interpersonal stressors experienced during deployment; women Veterans' experiences of premilitary trauma exposure; and unique stressors faced by women Veterans during the homecoming readjustment period. Given that most models of the impact of war zone deployment on PTSD are predicated on the experiences of male service members, women's expanding role in combat operations presents both an opportunity and a challenge to adapt these models to more effectively capture the experiences of female service members.

Potentially morally injurious events, such as perpetrating, failing to prevent, or bearing witness to acts that transgress deeply held moral beliefs and expectations may be deleterious in the long-term, emotionally, psychologically. behaviorally, spiritually, and socially (what we label as moral injury). Although there has been some research on the consequences of unnecessary acts of violence in war zones, the lasting impact of morally injurious experience in war remains chiefly unaddressed. To stimulate a critical examination of moral injury, we review the available literature, define terms, and offer a working conceptual framework and a set of intervention strategies designed to repair moral injury.

In this paper, we review recent research that documents the association between PTSD and intimate relationship problems in the most recent cohort of returning veterans and also synthesize research on prior eras of veterans and their intimate relationships in order to inform future research and treatment efforts with recently returned veterans and their families. We highlight the need for more theoretically-driven research that can account for the likely reciprocally causal association between PTSD and intimate relationship problems to advance understanding and inform prevention and treatment efforts for veterans and their families.

PTSD is an important outcome because it can affect quality of life, impairing psychosocial and occupational functioning and overall well-being. The literature on PTSD and quality of life in OEF/OIF Veterans is at an early stage, but the consistency of the evidence is striking. Our review indicates that the findings on PTSD and quality of life in OEF/OIF veterans are comparable to findings obtained from other war cohorts and from nonveterans as well. Even though the duration of PTSD in OEF/OIF Veterans is much shorter than in Vietnam Veterans, for example, those with PTSD in both cohorts are likely to experience poorer functioning and lower objective living conditions and satisfaction. The review ends with discussion of the implications of the evidence for research and clinical practice. Published by Elsevier Ltd C1 [Schnurr, Paula P.] Dartmouth Med Sch, Dartmouth, NS, Canada.

Design: Single group pre and post test. Setting: Research lab, community. Participants: Twenty-one individuals with Parkinson's disease. Interventions: Self-application of an auditory pacer set at a rate 25% faster than preferred cadence. Main outcome measures: Self-selected gait speed, cadence, stride length, and double support time with and without the pacer at the initial visit and after one week of pacer use. Results: During the initial visit, the auditory pacer improved gait speed (79.57 (18.13) cm/s vs. 94.02 (22.61) cm/s, P<0.0005), cadence (102.88 (11.34) step/min vs. 109.22 (10.23) steps/min, P=0.036) and stride length (94.33 (21.31) cm vs. 103.5 (22.65) cm, P=0.012). After one week, preferred gait speed was faster than the initial preferred speed (79.57 (18.13) vs. 95.20 (22.23) cm/s, P<0.0005). Stride length was significantly increased (94.33 (21.31) vs. 107.67 (20.01) cm, P=0.001). Double support time was decreased from 21.73 (5.23) to 18.94 (3.59)% gait cycle, P=0.016. Conclusion: Gait performance in people with Parkinson's disease improved significantly after walking with the auditory pacer for one week. C1 [Bryant, M. S.; Protas, E.

This article details the AE and serious adverse event (SAE) reporting summary developed for a large multi-center National Institutes of Health (NIH)-sponsored clinical trial. Purpose To review and analyze the large volume of AE data reported by 10 sites (806 SAEs and 19,034 AEs from August 2000 to May 2007) the automated SAE summary was developed. It was designed to ensure timeliness and clarity in the complex process of AE review and reporting. Methods The AE and SAE case report forms (CRFs) as well as the automated SAE summary were developed within a database management system developed by the Data Coordinating Center (DCC) which allowed for web-based data entry at the DCC and 10 sites and offered immediate overall and site-specific reports accessible by the DCC, site, and NIH project staff. Results The automated SAE summary pulled data from multiple CRFs to create a succinct and informative summary and allowed for prompt and easy reporting to the regulatory agencies. The summary was adaptable to the needs of reviewers because of the availability of multiple search options.

CA LiTMUS Study Grp TI Lithium treatment-moderate dose use study (LiTMUS) for bipolar disorder: rationale and design SO CLINICAL TRIALS LA English DT Article ID NEUROPSYCHIATRIC INTERVIEW MINI; PSYCHOTROPIC-DRUG PRESCRIPTION; CONTROLLED 18-MONTH TRIAL; PLACEBO-CONTROLLED TRIAL; PATTERN-MIXTURE MODELS; LOW SERUM LEVELS; QUALITY-OF-LIFE; I-DISORDER; DOUBLE-BLIND; MOOD DISORDERS AB Background Recent data indicate that lithium use for bipolar disorder has declined over the last decade and that lithium largely has been replaced with alternate, commercially promoted medications that may or may not result in better outcomes. Purpose This article describes the rationale and study design of LiTMUS, a multi-site, prospective, randomized clinical trial of outpatients with bipolar disorder. LiTMUS seeks to address whether initiating therapy at lower doses of lithium as part of optimized treatment (OPT, guideline-informed, evidence-based, and personalized pharmacotherapy) improves outcomes and decreases the need for other medication changes across 6 months of therapy. Methods LiTMUS will randomize 284 adults with bipolar disorder (Type I or II) across 6 study sites. The co-primary outcomes are overall illness severity on clinical global improvement scale for bipolar disorder and a novel measure, necessary clinical adjustments. This metric provides a composite that reflects both clinical response and tolerability. Other relevant outcomes include full symptomatic recovery, quality of life, suicidal behaviors, and moderators of suicidality. Results As of August 28th, 2009, we have consented 338 patients and randomized 281 for this study. Limitations The potential limitations of the study include an arbitrary definition of 'low, but effective' doses of lithium, lack of a placebo-controlled group, open treatment, and use of a new outcome measure (i.e., necessary clinical adjustments). Conclusion We expect that this study will inform our understanding of the effectiveness of low to moderate doses of lithium therapy for individuals with bipolar disorder.

It remains unclear, however, which children who have severe bronchiolitis (eg, an episode requiring hospitalization) will develop recurrent wheezing or asthma. Although many environmental and genetic factors may play a role in the pathway from bronchiolitis to asthma, this article focuses on the viruses that have been linked to bronchiolitis and how these viruses may predict or contribute to future wheezing and asthma. The article also discusses vitamin D as an emerging risk factor for respiratory infections and wheezing.

Testosterone administration has been shown to be an effective augmentation therapy in depressed hypogonadal men with selective serotonin reuptake inhibitor-resistant depression. However, the effects of low-dose testosterone as augmentation therapy in women with treatment-resistant depression have not been studied. Methods: Low-dose transdermal testosterone (300 mcg/day, Intrinsa, Procter and Gamble Pharmaceuticals) was administered to nine women with treatment-resistant depression in an 8 week open-label pilot protocol. Results: There was a statistically significant improvement in mean Montgomery-Asberg Depression Rating Scale (MADRS) scores at 2 weeks, sustained through the 8 week period. Two-thirds of subjects achieved a response to the treatment (decrease in MADRS score of 2.50%) and 33% achieved remission (final MADRS score <10) after 8 weeks of therapy. Mean levels of fatigue, as measured by the MADRS lassitude item, significantly decreased at all time points with a mean 38% decrease from baseline to 8 weeks. Conclusion: These preliminary pilot data suggest that low-dose transdermal testosterone may be an effective augmentation therapy in women with treatment-resistant depression. Further studies are warranted. CNS Spectr. 2009;14(12):688-694 C1 [Miller, Karen K.] Massachusetts Gen Hosp, Neuroendocrine Unit, Neuroendocrine Res Program Womens Hlth, Boston, MA 02114 USA.

Methods: A 9 year (1997-2006) retrospective claims analysis of adults enrolled in Florida Medicaid for at least 3 continuous years was canducted to determine the percentage who received both a minimally effective duration (>= 8 continuous weeks) and dose of first-line OCD pharmacotherapy during the year following their first ("index") OCD diagnosis. Results: Among 2,960,421 adult (>= 18 years of age) enrollees, 2,921 (0.1%) were diagnosed with OCD. Among the 2,825 OCD patients without comorbid Asperger syndrome or autism, 843 had newly-diagnosed OCD and at least 12 months of follow-up data after their index diagnosis. Among these 843 patients, 588 (69.7%) received first-line OCD pharmacotherapy but only 323 (38.3%) received a minimally effective pharmacotherapy trial in the year following their index diagnosis. Conclusions: Among clinically-diagnosed persons with OCD (<10% of those with the disorder), a minority of newly-diagnosed patients receive a minimally effective pharmacotherapy trial consistent with current standards of care. Reasons such as limited patient adherence and/or physician awareness of guidelines must be identified and redressed to ameliorate the patient, healthcare system, and economic burdens associated with OCD.

Methods: We retrospectively identified a cohort of patients with severe dry eye disease who had shown inadequate response to at least a 4-month course of treatment with twice-daily use of topical cyclosporine 0.05% but who showed significant improvement to more frequent dosing. Results: Twenty-two patients, including 13 patients with ocular graft-versus-host disease and 9 patients with primary or secondary Sjogren's syndrome, were included. After a minimum of a 2-month course of treatment with more frequent dosing of cyclosporine 0.05% (3 times a day in 7 patients and 4 times a day in 15 patients), overall dry eye symptoms were improved in 15 (68.2%) patients (9 patients with ocular graft-versus-host disease and 6 patients with Sjogren's syndrome). Mean corneal fluorescein staining scores (National Eye Institute scale of 0-15) improved (decreased) from the baseline (precyclosporine use) by -3.5 (mange, 0 to -7) in patients with ocular graft-versus-host disease (P <= 0.0008) and -2.8 (range, 0 to -5) in patients with Sjogren's syndrome (P <= 0.001). After treatment with high-frequency use of cyclosporine 0.05%, the global physician assessment of dry eye status was favorable (improved) in 16 (72.7%) patients. Three (13.6%) patients reported new-onset symptoms of burning or irritation with the use of high-frequency dosing of topical cyclosporine. No other associated adverse effect was reported. Conclusion: These data suggest that patients with severe dry eye may require more frequent dosing of topical cyclosporine 0.05% than twice daily.

TI Penetrating Keratoplasty for Invasive Fungal Keratitis Resulting From a Thorn Injury Involving Phomopsis species SO CORNEA LA English DT Article DE fungal keratitis; penetrating keratoplasty; Phomopsis species; infectious keratitis; rose fungus AB Purpose: The purpose of this Study was to report a case of Phomopsis fungal keratitis that was diagnosed 2 months after a rose thorn injury that occurred while gardening. Methods: The authors conducted a retrospective case report with literature review. Results: Deep stromal keratitis with extension of hyphae through Descemet's membrane was treated by therapeutic keratoplasty combined with oral and topical antifungal medications. The causative organism, a Phomopsis species, was identified by culture of the surgical specimens. Phomopsis, a plant fungus, has not been previously reported as a cause of human fungal keratitis. One year after the initial surgery, visual rehabilitation was accomplished with a repeat cornea transplant and cataract extraction with return of vision to 20/25. Conclusions: Advanced fungal keratitis can be successfully treated by a combination of surgery to debulk the infectious organisms and pre- and postoperative medical therapy. Prompt recognition of fungal keratitis will increase the likelihood of cure. Phomopsis species, ubiquitous plant fungi, can cause infectious keratitis in humans.

Method: A 52-year-old woman presented with decreased vision in her left eye. Three months previously, the patient had undergone laser in situ keratomileusis in her left eye with incorrect axis treatment. All potential options were discussed in detail with the patient. After consideration, she proceeded with AK as a tissue-sparing maneuver and planned to evaluate other options in the future. Results: The patient received a pair of 60-degree arcuate incisions at a 7-mm optical zone. On the first postoperative visit, dramatic improvement in uncorrected visual acuity was noted along with the reduction of ghosting and visual blur. The refractive error was +0.50-1.00 x 165 degrees. At the final 1-year follow up, uncorrected visual acuity was 20/25. The residual refractive error was +0.50-0.75 x 173 degrees. Conclusions: To the best of our knowledge, this is the first reported case of AK in a patient with high astigmatism resulting from incorrect axis treatment during Laser in situ keratomileusis. Visual recovery is rapid and refractive changes are stable. For refractive surgeons familiar with AK, this tissue neutral surgical approach may be a first choice option to improve uncorrected visual acuity and reduce unwanted and disabling optical effects secondary to high astigmatism.

The duration of untreated psychosis (DUP) is considered to be one of the most important determinants of outcome in the first episode of psychosis. However, the focus on decreasing the length of untreated illness tends to overlook the difficult task of making sense of psychotic experiences during a first episode. Using a qualitative analysis of narratives obtained from interviews with an individual and her husband, we examine what delayed her seeking help, how she became convinced that she needed treatment and what this meant for her and her husband. Additionally, we look at the five-year development of both a literal and a figurative space within which both the subject and her husband came to utilize, whether consciously or unconsciously, the 'stories' of her psychotic experiences to construct a shared and even 'safe' and familiar means of spousal connection. The exploration of this shared space reveals the normative and moral values embedded in the concept of DUP and suggests alternative ways of understanding the help-seeking behaviors in early psychosis.

To address this question, we are studying the evolution of a mammalian toxin, the serine protease BLTX [1], from the salivary glands of the North American shrew Blarina brevicauda. Here, we examine the molecular changes responsible for promoting BLTX toxicity. First, we show that regulatory loops surrounding the BLTX active site have evolved adaptively via acquisition of small insertions and subsequent accelerated sequence evolution. Second, these mutations introduce a novel chemical environment into the catalytic cleft of BLTX. Third, molecular-dynamic simulations show that the observed changes create a novel chemical and physical topology consistent with increased enzyme catalysis. Finally, we show that a toxic serine protease from the Mexican beaded lizard (GTX) [2] has evolved convergently through almost identical functional changes. Together, these results suggest that the evolution of toxicity might be predictable-arising via adaptive structural modification of analogous labile regulatory loops of an ancestral serine protease-and thus might aid in the identification of other toxic proteins.

Mortality rates of patients with diabetes mellitus (DM) on chronic dialysis exceed those of non-DM patients. ESRD and dialysis add to the complexity of glycemic management in this population. Abnormal glucoregulation includes reduced insulin sensitivity and renal clearance of the hormone. Implementation of dialysis affects glucose and insulin levels, while increasing insulin sensitivity. Tight glycemic control carries an increased risk of hypoglycemia in ESRD. Monitoring glycemic control with hemoglobin A(1c) (HbA(1c)) levels may be suboptimal because of analytical and clinical variability of the test. Recent studies on HbA(1c) and clinical outcomes in this population present complementary results on the role of glycemic control in patients with DM with ESRD.

Development of microscale devices and screening assays incorporating primary human cells can potentially provide better, faster and more efficient prediction of in vivo toxicity and clinical drug performance. With this goal in mind, large strides have been made in the area of microfluidics to provide in vitro surrogates that are designed to mimic the physiological architecture and dynamics. More recent advancements have been made in the development of in vitro analogues to physiologically-based pharmacokinetic (PBPK) models - a mathematical model that represents the body as interconnected compartments specific for a particular organ. In this review we highlight recent advancements in human hepatocyte microscale culture, and describe the next generation of integrated devices, whose potential allows for the high throughput assessment of drug metabolism, distribution and pharmacokinetics.

Recent findings Although it is impossible to improve muscle relaxation (defined as absence of electrical activity) of intact resting muscle by hypnotics, analgesia is required to prevent pain-evoked muscular contractions during surgery. Regional anesthesia, as well as hypnotics and opioids, promotes intraoperative muscle relaxation. Neuromuscular blocking agents (NMBAs) induce dose-dependent muscle relaxation, but their effects vary widely between individuals, and postoperative residual curarization (PORC) exposes patients to additional risk. Low doses of NMBAs should, therefore, be used, effects be monitored quantitatively by acceleromyography, and residual neuromuscular block be reversed. Acetylcholinesterase inhibitor reversal can cause respiratory side effects, so the lowest efficacious dose should be used: as little as 0.015-0.025mg kg(-1) of neostigmine is required at a train-of-four count of four with minimal fade. Sugammadex encapsulates steroidal NMBAs. Sugammadex reversal is a viable approach to rapidly antagonize deep levels of neuromuscular block. Summary Optimal muscle relaxation for ambulatory surgery results from a judicious combination of regional anesthesia, opioids, and low doses of NMBAs. The effects of NMBAs should be monitored quantitatively by acceleromyography and reversed appropriately.

The aim of this review is to outline the recent evidence that effective physician communication with families, and proactive palliative care interventions can improve outcomes for both patients and family, members in the ICU. Recent findings New data from the ICU correlates physician ability to identify and respond to emotion and to effectively share prognostic information with improved outcomes. Furthermore, proactive palliative care interventions that promote family meetings, use of empathic communication skills, and targeted palliative care consultations can improve family satisfaction, reduce length of stay in the ICU and reduce adverse family bereavement outcomes. Summary Empathic communication, skilful discussion of prognosis, and effective shared decision-making are core elements of quality care in the ICU, represent basic competencies for the ICU physician, and should be emphasized in future educational and clinical interventions.

Recent findings Growth hormone deficiency is associated with low bone mass in children and adults, in addition to its well established impact on growth. Although GH and insulin-like growth factor I have direct skeletal actions, it is also possible that disordered parathyroid hormone secretion or effect may mediate some of the deleterious consequences of GH deficiency on bone. The benefits of GH replacement on bone mineral density have been demonstrated in many studies, but it remains unclear whether these are consistent across patient subgroups. The impact of GH replacement on fracture risk has not been definitively established. The positive effects of GH administration on growth are well established in childhood-onset growth hormone deficiency, as well as in several other pediatric conditions. Data on investigational uses of GH are also presented. Summary GH may have a relevant role in bone physiology and several disease states in addition to growth hormone deficiency. Although the salutary effects of GH replacement on bone growth and bone density are well characterized, additional studies are required to examine the impact of GH replacement on fracture risk as well as potential benefits in osteoporosis.

Summary Pregnancy is a hypercoagulable state, and inherited thrombophilia increases this risk further. Despite the risks, the actual incidence of venous thromboembolism remains low, and therefore, the widespread use of anticoagulants for pregnant women with inherited thrombophilia is not advised. Although randomized, placebo-controlled trials investigating the risks and benefits of anticoagulation have not been performed, there are data to support the use of low molecular weight heparin for high and intermediate-risk women. We will review these data and treatment recommendations, which are based on retrospective and case-control studies as well as expert opinion and consensus statements.

TI AIRE in the thymus and beyond SO CURRENT OPINION IN IMMUNOLOGY LA English DT Review ID PROMISCUOUS GENE-EXPRESSION; T-CELL TOLERANCE; AUTOIMMUNE REGULATOR PROTEIN; ORGAN-SPECIFIC AUTOIMMUNITY; EPITHELIAL-CELLS; LYMPH-NODE; SELF-TOLERANCE; DEFICIENT MICE; PHD FINGER; IMMUNE TOLERANCE AB The maintenance of immunologic self-tolerance requires the coordination of multiple complementary systems. Studies of the Autoimmune Regulator (Aire) gene have revealed that Aire promotes self-tolerance partly by inducing the transcription of a wide array of tissue-specific antigens (TSAs), particularly in the thymus. The importance of Aire is highlighted by the fact that patients and mice defective in Aire expression develop a multi-organ autoimmune syndrome. In this review we discuss recent progress in our understanding of Aire's control of immune tolerance at the cellular and molecular levels, and also address the potential importance of Aire expression both in the thymus and in the peripheral lymphoid organs. The detection of both Aire and TSA expression by cell populations outside of the thymus raises the possibility that such expression may play a relevant role in the maintenance of self-tolerance.

The two human TCRs bind their self-peptide-MHC ligands with an altered topology, while the three mouse receptors recognize a self-peptide that only partially fills the MHC-binding groove. In most cases the peptide is contacted only by a subset of available TCR complementarity-determining loops and there is a paucity of hydrogen bonds from TCR to peptide. These suboptimal binding properties may have enabled escape from negative thymic selection, While only minute amounts of antigen are typically available for negative selection, the antigens recognized by many autoimmune TCRs are abundant in the target organ. Such compensatory mechanisms can allow self-reactive T cells with altered TCR-binding properties to be pathogenic.

This review summarizes current treatments for recurrent high-grade gliomas with an emphasis on more novel approaches. Recent findings There is increasing evidence that antiangiogenic therapies have activity in high-grade gliomas. Recently, the United States Food and Drug Administration granted accelerated approval of bevacizumab, a humanized monoclonal antibody against vascular endothelial growth factor, for the treatment of recurrent glioblastomas. Bevacizumab decreases corticosteroid requirements and improves radiologic response rates and progression-free survival. The extent to which these agents prolong overall survival remains to be determined. There is also emerging evidence that other therapies such as dose-dense and metronomic temozolomide regimens, targeted molecular agents, and other antiangiogenic therapies may have activity in recurrent high-grade gliomas. Summary Although there has been progress in treating recurrent high-grade gliomas, the prognosis remains poor and much work still needs to be done to improve on the current results of antiangiogenic and targeted molecular therapies, as well as other novel therapies.

However, the exact mechanisms are not completely clear. Cell transplantation has been proposed as an alternative treatment of liver diseases. Recent progress has been reported on the generation of stem/progenitor cells that may differentiate toward the hepatic lineage. However, it is currently difficult to determine which of the stem/progenitor cell populations are the best for therapy of a given disease. Recent findings The limited access to donor human hepatocytes has led to a great interest in the generation of hepatocyte-like cells. Several potential cell sources have been identified However, general standardization of the methods to evaluate these cells is particularly important for the promise of stem/progenitor-derived hepatocyte-based therapies. Moreover, innovations aimed at improving hepatocyte delivery, survival, and engraftment have recently opened the field of organ engineering that may improve liver repopulation. Summary Here we review current evidence reported from the perspective of potential clinical applications of different hepatic cell sources with repopulation capacities and the future perspectives and tools that can facilitate the translation of laboratory work into clinical success.

TI Healthcare for children with autism: the Autism Treatment Network SO CURRENT OPINION IN PEDIATRICS LA English DT Editorial Material DE autism; collaboration; epidemiology; medical care; standards ID SPECTRUM DISORDERS; GASTROINTESTINAL SYMPTOMS; REGRESSION; EXPENDITURES; POPULATION; MELATONIN AB Purpose of review Autism spectrum disorders (ASDs) are a group of a neurodevelopmental disorders affecting social, communicative, and behavioral functioning. ASD is a heterogeneous group of disorders, often accompanied by associated medical issues. Thus, the development of effective treatments is a complex task requiring consideration of diverse etiologic and phenotypic characteristics. Recent attention to the diagnosis and treatment of medical conditions in ASD children has led to the formation of a new international collaboration to improve autism care, the Autism Treatment Network (ATN). Recent findings Numerous studies have highlighted the high prevalence of gastrointestinal and sleep disorders among ASD children. Problems in communication - including being nonverbal - make the diagnosis and treatment of these conditions more difficult. Although a number of studies suggest links between neurologic impairments and gastrointestinal dysfunction and disordered sleep, these relationships remain unproven. Recent work by the ATN has begun the development of clinical guidelines in these areas, based on clinical consensus, adapting the model developed by the Cystic Fibrosis Foundation. New funding has also supported the network's development of a robust clinical research program focused on improving the physical health and care of children with ASD. These efforts promise more systematic and consistent approaches to diagnosis and treatment of these conditions. Summary Improved understanding of the underlying pathology of ASD and associated conditions, and the development of a common purpose across multiple treating sites, can improve the consistent and coordinated healthcare of children with autism.

Thus, presently there are no effective cures for these diseases. Some phenotypic as well as mechanistic features, common to the most of NDs, can be linked to epigenetic defects, that can lead to alteration of acetylation homeostasis and impairment of the histone acetyltransferase (HAT): histone deacetylase (HDAC) balance. Here we survey most of the recent applications of HDAC inhibitors in the cited NDs, and we make the point of our (up to now) knowledge about the involvement of singular HDAC/SIRT isoform in NDs and other CNS pathologies.

RNAi refers to an evolutionarily conserved cellular mechanism for sequence-specific post-transcriptional gene silencing, in which double-stranded RNAs promote selective degradation of homologous cellular mRNAs. Because RNAi-based techniques can be employed to reduce expression of specific genes, this approach holds great promise as a therapy for diverse diseases, including devastating neurodegenerative disorders such as Alzheimer's, Parkinson's, and Huntington's diseases and amyotrophic lateral sclerosis (ALS). Importantly, in recent years RNAi has also emerged as a key tool in target identification and validation studies designed to complement traditional (i.e., small molecule-based) drug development strategies. These studies harness the power of RNAi-mediated reverse genetics to probe disease-associated pathways in both cell-based and animal models, and thus may provide critical data needed to focus drug development efforts around disease-relevant targets. This review highlights recent progress in the preclinical development of RNAi-based therapeutics for neurodegenerative disease and discusses the particular challenges that disorders of the central nervous system (CNS) pose for this approach. It further describes current applications of RNAi techniques for target identification and validation studies and underscores the importance of this methodology to developing treatments for neurological diseases.

Can it be prevented? The European experience suggests that adding the electrocardiogram (ECG) to the standard medical and family history and physical examination can decrease cardiac deaths by 90%. However, there has not been a randomized trial to demonstrate such a reduction. While there are obvious differences between the European and American experiences with athletes including very differing causes of athletic deaths, some would highlight the European emphasis on public welfare vs the protection of personal rights in the USA. Even the authors of this systematic review have differing interpretation of the data: some of us view screening as a hopeless battle against Bayes, while others feel that the ECG can save lives. What we all agree on is that the USA should implement the American Heart Association 12-point screening recommendations and that, before ECG screening is mandated, we need to gather more data and optimize ECG criteria for screening young athletes.

TI Diameter of Involved Nerves Predicts Outcomes in Cutaneous Squamous Cell Carcinoma with Perineural Invasion: An Investigator-Blinded Retrospective Cohort Study SO DERMATOLOGIC SURGERY LA English DT Article ID SKIN-CANCER; HEAD; NECK; RISK AB BACKGROUND Perineural invasion (PNI) has been associated with poor prognosis in cutaneous squamous cell carcinoma (CSCC), but it is unclear how different degrees of nerve involvement affect prognosis. OBJECTIVE To determine whether the diameter of nerves invaded by CSCC affects outcomes of recurrence, metastasis, and disease-specific and overall survival. METHODS A retrospective cohort study was conducted of patients with CSCC with PNI. Dermatopathologists blinded to subject outcomes determined the diameter of the largest involved nerve. RESULTS Data were obtainable for 48 patients. Small-caliber nerve invasion (SCNI) of nerves less than 0.1 mm in diameter was associated with significantly lower risks of all outcomes of interest. Disease-specific death was 0% in subjects with SCNI, versus 32% in those with large-caliber nerve invasion (LCNI) (p=.003). Other factors associated with significantly worse survival were recurrent or poorly differentiated tumors or tumor diameter of 2 cm or greater or depth of 1 cm or greater. On multivariate analysis, only tumor diameter and age predicted survival. CONCLUSIONS The individual prognostic significance of factors associated with poor survival remains uncertain. Small-caliber nerve invasion may not adversely affect outcomes. Defining PNI as tumor cells within the nerve sheath and routine recording of diameter of involved nerves, tumor depth, and histologic differentiation on pathology reports will facilitate further study.

Hanke, C. William Kimball, Alexa Boer TI Academic Productivity and Affiliation of Dermatologic Surgeons SO DERMATOLOGIC SURGERY LA English DT Article ID WORKFORCE AB BACKGROUND Because Mohs fellowship training typically incorporates a research component, as required by the Mohs College for fellowship certification, we evaluated whether Mohs microscopic surgery fellowship-trained (MMSFT) dermatologic surgeons were more likely to join academic institutions and demonstrate greater activity in teaching, research, and scientific writing than non-fellowship-trained surgeons (NMMSFT). METHODS Responses to the 2002 and 2005 American Academy of Dermatology Practice Profile survey comparing practice settings, proportion of time spent in various practice settings, and professional roles were compared between the two groups. RESULTS MMSFT dermatologic surgeons were 5 times as likely to be in full-time academic practice and 3 times as likely to be in part-time academia as NMMSFT dermatologic surgeons. Consistent with their greater presence in academia, in 2004, 47% of MMSFT dermatologist surgeons participated in teaching, compared with 19% of NMMSFT surgeons (p=.001) and 16% of all dermatologists (p=.001). Twenty-two percent of MMSFT dermatologic surgeons were involved in research, compared with only 4% of NMMSFT dermatologic surgeons (p=.001) and 8% of all dermatologists (p <.05). CONCLUSIONS Academic productivity of dermatologic surgeons appears to be associated with Mohs fellowship training. The level of teaching and research was significant even in MMSFT surgeons who were not in full- or part-time academic faculty positions. This suggests a strong tradition of academic productivity for dermatologic surgeons outside traditional academic institutions.

With limited resources, disease-oriented therapies and prevention measures take priority. In this paper, I intend to describe the moral framework for considering palliative care as a public health priority in resource-poor countries. A distributive theory of justice for health care should consider integrative palliative care as morally required as it contributes to improving normal functioning and preserving opportunities for the individual. For patients requiring terminal care, we are guided less by principles of justice and more by the duty to relieve suffering and society's commitment to protecting the professional's obligation to uphold principles of beneficence, compassion and non-abandonment. A fair deliberation process is necessary to allow these strong moral commitments to serve as reasons when setting priorities in resource poor countries.

Normal valve development involves multiple signaling pathways, and recently roles have been identified for extracellular matrix components, including glycosaminoglycans. We, therefore, explored the role of the glycosaminoglycan chondroitin sulfate during zebrafish cardiac development. Beginning at 33 hr, there is a distinct zone of chondroitin sulfate expression in the atrioventricular (AV) boundary, in the cardiac jelly between the endocardium and myocardium. This expression is both spatially and temporally restricted, and is undetectable after 48 hr. Chemical as well as genetic inhibition of chondroitin synthesis results in AV canal (AVC) defects, including loss of the atrioventricular constriction, blood regurgitation, and failure of circulation. Lack of chondroitin disrupts a marker of cell migration, results in a loss of myocardial and endothelial markers of valvulogenesis, and misregulates bone morphogenetic protein expression, supporting an early role in AVC development. In summary, we have defined a requirement for chondroitin sulfate expression in the normal patterning of the AV boundary, suggesting that this component of the cardiac jelly provides a necessary signal in this critical transition in vertebrate cardiogenesis.

TI Transgenically Induced GAD Tolerance Curtails the Development of Early beta-Cell Autoreactivities but Causes the Subsequent Development of Supernormal Autoreactivities to Other beta-Cell Antigens SO DIABETES LA English DT Article ID GLUTAMIC-ACID DECARBOXYLASE; NONOBESE DIABETIC MICE; MYELIN BASIC-PROTEIN; NOD MICE; T-CELLS; AUTOIMMUNE-DISEASE; PANCREATIC-ISLETS; TH2 RESPONSES; PRONE MICE; MOUSE AB OBJECTIVE-To study how tolerance to GAD65 affects the development of autoimmunity to other beta-cell autoantigens (beta-CAAs) in GAD65-transgenic (GAD-tg) NOD mice. RESEARCH DESIGN AND METHODS-We used ELISPOT to characterize the frequency and functional phenotype of T-cell responses to GAD65 and other beta-CAAs at different ages in GAD-tg mice and their NOD mouse littermates. RESULTS-In young GAD-tg mice, Th1 responses to GAD65's dominant determinants were 13-18% of those in young NOD mice. This coincided with a great reduction in Th1 responses to other beta-CAAs. Evidently, GAD65-reactive T-cells are important for activating and/or expanding early autoreactivities in NOD mice. As GAD-tg mice aged, their T-cell responses to GAD65 remained low, but they developed supernormal splenic and pancreatic lymph node T-cell autoimmunity to other beta-CAAs. Apparently, the elimination/impairment of many GAD65-reactive T-cells allowed other beta-CAA-reactive T-cells to eventually expand to a greater extent, perhaps by reducing competition for antigen-presenting cells, or homeostatic proliferation in the target tissue, which may explain the GAD-tg mouse's usual disease incidence. CONCLUSIONS-Transgenically induced reduction of GAD65 autoreactivity curtailed the development of early T-cell responses to other beta-CAAs. However, later in life, beta-CAA-reactive T-cells expanded to supernormal levels. These data suggest that early beta-cell autoreactivities are mutually dependent for support to activate and expand, while later in the disease process, autoantigen-specific T-cell pools can expand autonomously. These findings have implications for understanding type 1 diabetes immunopathogenesis and for designing antigen-based immunotherapeutics.

TI Emphasis on Carbohydrates May Negatively Influence Dietary Patterns in Youth With Type 1 Diabetes SO DIABETES CARE LA English DT Article ID GLYCEMIC CONTROL; CHILDREN; ADOLESCENTS; BEHAVIORS AB OBJECTIVE - To assess perceptions of healthful eating and the influence of diabetes management on dietary behaviors among youth with type 1 diabetes and parents. RESEARCH DESIGN AND METHODS - Youth with type 1 diabetes (n = 35), ages 8-21 years, and parents participated in focus groups. Focus group recordings were transcribed and coded into themes. Clinical data were abstracted from the electronic medical record. RESULTS - Central topics were perceptions of healthful eating and the impact of diabetes management on diet. An emphasis on limiting postprandial glycemic excursions occasionally contradicted the traditional perception of healthful eating, which emphasized consumption of nutrient-dense whole foods in favor of prepackaged choices. Whereas fixed regimens required more rigid diets, basal-bolus regimens provided more opportunities for unhealthful eating. Most youth perceived "refined" grains as more healthful grains. CONCLUSIONS - For youth with type 1 diabetes and parents, an emphasis on carbohydrate quantity over quality may distort beliefs and behaviors regarding healthful eating.

Retrospective studies suggest that drivers with type I diabetes experience more collisions and citations than their nondiabetic spouses, We present the first prospective data documenting the occurrence of apparent neuroglycopenia-related driving performance impairments. RESEARCH DESIGN AND METHODS - We completed the initial screening of 452 drivers from three geographically diverse centers who then reported monthly occurrences of driving "mishaps," including collisions, citations, losing control, automatic driving, someone else taking over driving, and moderate or severe hypoglycemia while driving. RESULTS - Over 12 months, 52% of the drivers reported at least one hypoglycemia-related driving mishap and 5% reported six or more. These mishaps were related to mileage driven, history of severe hypoglycemia, and use of insulin pump therapy. CONCLUSIONS - Many individuals with type I diabetes report hypoglycemia-related driving events. Clinicians should explore the recent experiences with hypoglycemia while driving and the risk of future events.

TI Effects of Exenatide Alone and in Combination With Daclizumab on beta-Cell Function in Long-Standing Type 1 Diabetes SO DIABETES CARE LA English DT Article ID ANTI-CD3 MONOCLONAL-ANTIBODY; NOD MICE; EXENDIN-4; REPLICATION; ONSET; IMMUNOSUPPRESSION; TRANSPLANTATION; REGENERATION; RESPONSES; REVERSAL AB OBJECTIVE - in patients with long-standing type 1 diabetes, we investigated whether improved P-cell function can be achieved by combining intensive insulin therapy with agents that may 1) promote beta-cell growth and/or limit beta-cell apoptosis and 2) weaken the anti-beta-cell autoimmunity. RESEARCH DESIGN AND METHODS - For this Study, 20 individuals (mean age 39.5 +/- 11.1. years) with long-standing type I diabetes (21.3 +/- 10.7 years) were enrolled in this prospective open-label crossover trial. After achieving optimal blood glucose control, 16 subjects were randomized to exenatide with or Without daclizumab. Endogenous insulin production was determined by repeatedly measuring serum C-peptide. RESULTS - In 85% of individuals with long-standing type 1. diabetes who were screened for participation in this trial, C-peptide levels >= 0.05 ng/ml (0.02 nmol/1) were found. Residual P-cells responded to physiological (mixed-meal) and pharmacological (arginine) stimuli. During exenatde treatment, patients lost 4.1 +/- 2.9 kg body wt and insulin requirements declined significantly (total daily close on exenatide 0.48 +/- 0.11 Vs. 0.55 +/- 0.13 units . kg(-1) . day(-1) without exenatide; P = 0.0062). No signs of further activation of the underlying autoimmune disease were observed. Exenatide delayed gastric emptying, suppressed endogenous incretin levels, but did not increase C-peptide secretion. CONCLUSIONS - In long-standing type 1. diabetes, which remains an active autoimmune disease even decades after its onset, surviving beta-cells Secrete insulin in a physiologically regulated manner. However, the combination of intensified insulin therapy, exenatide, and daclizumab did not induce improved function of these remaining beta-cells.

Thus, we studied the extent to which specific autoantibodies are predictive of type 1 diabetes. RESEARCH DESIGN AND METHODS - Two cohorts were derived from the first screening for islet cell autoantibodies (ICAs) in the Diabetes Prevention Trial-Type I (DPT-1). Autoantibodies to GAD 65 (GAD65), insulinoma-associated antigen-2 (ICA512), and insulin (micro-IAA [mIAA]) were also measured. Participants were followed for the occurrence of type 1 diabetes. One cohort (Questionnaire) included those who did not enter the DPT-1 trials, but responded to questionnaires (n = 28,507, 2.4% ICA(+)). The other cohort (Trials) included DPT-1 participants (n = 528, 83.3% ICA(+)). RESULTS - in both cohorts autoantibody number was highly predictive of type 1. diabetes (P < 0.001). The Questionnaire cohort was used to assess prediction according to the type of autoantibody. As single autoantibodies, ICA (3.9%), GAD65 (4.4%), and ICA512 (4.6%) were similarly predictive of type 1 diabetes in proportional hazards models (P < 0.001 for all). However, no subjects with mIAA as single autoantibodies developed type I diabetes. As second autoantibodies, all except mIAA added significantly (P < 0.001) to the prediction of type 1 diabetes. Within the positive range, GAD65 and ICA autoantibody titers were predictive of type I diabetes. CONCLUSIONS - The data indicate that the number of autoantibodies is predictive of type 1 diabetes. However, mIAA is less predictive of type 1 diabetes than other autoantibodies. Autoantibody number, type of autoantibody, and autoantibody titer must be carefully considered in planning prevention trials for type 1 diabetes.

Thus, the differential diagnosis of various types and forms of diabetes is of great practical importance. This is particularly true for monogenic disease forms where some spectacular applications of pharmacogenetics have recently been described. Unfortunately, most patients with monogenic diabetes such as maturity-onset diabetes of the young (MODY) or neonatal diabetes have not undergone diagnostic molecular testing, so they can not benefit from the progress seen in this field. The reasons for this include the complexity and cost of molecular diagnostics. One of ways to change this situation is to find an efficient and cheap test to screen thousands of patients for specific forms of monogenic diabetes. These tests can be based on biomarkers discovered by one of two general strategies: a candidate approach or a systematic search based on metabonomics or proteonomics. This review summarizes recent advances in the search for putative biomarkers and the perspectives of the future progress. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

TI Loss of islet sympathetic nerves and impairment of glucagon secretion in the NOD mouse: relationship to invasive insulitis SO DIABETOLOGIA LA English DT Article DE Alloxan; Diabetes; 6-Hydroxydopamine; Hypoglycaemia; Lymphocytes; Neuropathy; NOD mice; Tyramine ID STREPTOZOTOCIN-DIABETIC RATS; DEFECTIVE GLUCOSE COUNTERREGULATION; NERVOUS-SYSTEM; PERFUSED PANCREAS; BB RATS; HYPOGLYCEMIA; RESPONSES; STIMULATION; ALPHA; CELLS AB We hypothesised that non-obese diabetic mice (NOD) mice have an autoimmune-mediated loss of islet sympathetic nerves and an impairment of sympathetically mediated glucagon responses. We aimed: (1) to determine whether diabetic NOD mice have an early impairment of the glucagon response to insulin-induced hypoglycaemia (IIH) and a coincident loss of islet sympathetic nerves; (2) to determine whether invasive insulitis is required for this nerve loss; and (3) to determine whether sympathetically mediated glucagon responses are also impaired. We measured glucagon responses to both IIH and tyramine in anaesthetised mice. We used immunohistochemistry to quantify islet sympathetic nerves and invasive insulitis. The glucagon response to IIH was markedly impaired in NOD mice after only 3 weeks of diabetes (change, -70%). Sympathetic nerve area within the islet was also markedly reduced at this time (change, -66%). This islet nerve loss was proportional to the degree of invasive insulitis. More importantly, blocking the infiltration prevented the nerve loss. Mice with autoimmune diabetes had an impaired glucagon response to sympathetic nerve activation, whereas those with non-autoimmune diabetes did not. The invasive insulitis seen in diabetic NOD mice causes early sympathetic islet neuropathy. Further studies are needed to confirm that early sympathetic islet neuropathy is responsible for the impaired glucagon response to tyramine. C1 [Taborsky, G. J., Jr.; Mei, Q.; Hackney, D.

We analyzed 215 formalin-fixed, paraffin-ern bedded liver needle biopsies from patients infected with HCV genotypes 1b and 2. HCV RNA extracted from paraffin sections were quantified by means of a TaqMan real-time reverse transcription-polymerase chain reaction method. The quantification of HCV RNA in liver tissue was correlated with the amount of HCV detected by immunohistochemistry (IHC) on paired frozen biopsies, the HCV RNA load in the serum, and the main serum tests of liver function and cholestasis. HCV RNA was detected by real-time reverse transcription-polymerase chain reaction in 169 liver biopsies (78.6%) with a mean value of 13.59 +/- 37.25 IU/ng. Tissue HCV RNA levels strongly correlated with the IHC results (P < 0.001, Spearman test), HCV serum load (P < 0.001), aspartate aminotransferase (P = 0.001), gamma-glutamyl transpeptidase (P = 0.012), and aspartate aminotransferase/alanine aminotransferase ratio (P = 0.029). HCV RNA was amplified in up to 7-year-old archival tissue samples. Real-time HCV RNA quantification on archival liver tissue may be clinically relevant in case of "occult" HCV infection or for the diagnosis of patients with known HCV infection and hepatic dysfunction but seronegative for HCV RNA. The assessment of the levels of HCV RNA in the liver might also be important for monitoring the effectiveness of antiviral therapy and the progression of disease in patients with chronic HCV hepatitis.

The serotonin transporter regulates the intensity and duration of serotonin signaling in the gut and is, therefore, an attractive candidate gene for irritable bowel syndrome. Previous studies investigating the 5-HTTLPR and Stin2 VNTR polymorphisms of the serotonin transporter have proved inconclusive. In this exploratory study we therefore expanded the search for a possible association of the serotonin transporter with irritable bowel syndrome to include not only the 5-HTTLPR and Stin2 VNTR length polymorphisms, but also the functional single nucleotide polymorphism rs25531. We genotyped 186 patients with irritable bowel syndrome and 50 healthy control subjects raging in age from 18 to 70 years. Carriers of the rare G allele of rs25531 had approximately threefold increased odds of irritable bowel syndrome compared with healthy controls (OR 3.3, 95% CI 1.1-9.6). Our findings suggest that further investigation of the possible role of the serotonin transporter in the etiology of IBS is warranted.

Current therapeutic agents fail to adequately address patient needs in terms of efficacy, tolerability and treatment-related adverse events. Consequently there is on urgent need to develop more effective and better tolerated pharmacotherapies for improved treatment of these illnesses. Asenapine maleate is a novel drug recently approved by the Food and Drug Administration for treatment of acute schizophrenia and for manic or mixed episodes of bipolar I disorder with or without psychotic features in adults. It has a unique pharmacologic profile as it targets multiple dopamine, serotonin and adrenergic receptor subtypes with variable affinities. Such drug/receptor interactions contribute to the antipsychotic and antimonic efficacy of asenapine. Asenapine was effective in animal models predictive of antipsychotic activity and clinical trials indicate that it improves the symptoms of acute schizophrenia and bipolar mania, is well tolerated and has a favorable safety profile. This monograph provides on up to dote review of the preclinical and clinical profiles of asenapine, including new clinical data in patients with schizophrenia and bipolar mania.

METHODS: One hundred anorexia nervosa patients (66 acAN and 34 recAN) and 88 HCW were included in our study. Psychopathology was assessed by self-report questionnaires [Symptom Check List 90 Revised (SCL-90-R), Eating Disorder Inventory-2 (EDI-2)] as well as by interview [Structured Interview of Anorexia Nervosa and Bulimic Syndromes (SIAB-EX)] and compared using multivariate analysis of variance. Plasma leptin levels were determined using enzyme linked immunosorbent assay. RESULTS: Mean comparisons indicated highly significant differences between acAN and recAN subjects on all psychopatholgy variables, except for perfectionism. RecAN subjects did not differ from HCW. Partial weight recovery was associated with decreasing levels of psychopathology. Correlational analyses suggested strong negative associations between leptin levels and psychopathology. CONCLUSION: Prolonged malnutrition, as indicated by suppressed plasma leptin levels, is strongly related to eating disorder-specific as well as general psychopathological symptoms. Weight recovery is associated with the absence of psychopathology. These data emphasize the interaction between somatic and psychological variables. (Eating Weight Disord. 14: e205-e211, 2009).

TI Progressive multifocal cystlike cortical tubers in tuberous sclerosis complex: Clinical and neuropathologic findings SO EPILEPSIA LA English DT Article DE Tuberous sclerosis complex; Tuber; Epileptogenesis; Neuropathology; White matter disease ID EPILEPSY AB P>Tuberous sclerosis complex (TSC) is a genetic disease characterized by the presence of hamartomatous lesions in multiple organs and cortical tubers in the brain. The majority of patients with TSC have epilepsy, although the mechanisms underlying epileptogenesis remain unknown. Tubers are traditionally thought to be stable lesions that result from abnormal corticogenesis in early fetal development. Recently, cystlike tubers have been identified in nearly half of patients with TSC, although the spectrum and natural history of these lesions remains unknown. Herein we report eight children with a high burden of cystlike tubers and present detailed clinical information on two children with documented progression. We also report neuropathologic findings of one of the cystlike cortical tubers resected in epilepsy surgery. These cases support the notion that cystlike tubers in TSC are not static lesions and can exhibit evolving characteristics over time. Further work evaluating how these lesions relate to epileptogenesis needs to be done. C1 [Chu-Shore, Catherine J.; Thiele, Elizabeth A.] Massachusetts Gen Hosp, Dept Neurol, Boston, MA 02114 USA.

Some cortical tubers are thought to be epileptogenic while others are not. This study aimed to evaluate whether tuber burden, size or type seen on magnetic resonance imaging (MRI) co-registers with interictal epileptiform discharges on electroencephalogram (EEG). EEG and MRI data from 69 patients with TSC were reviewed by dividing the cerebrum into four quadrants. Quadrants containing greatest tuber burden, largest tuber, calcified tubers, cyst-like tubers, and no tubers were identified on MRI. For EEG analysis, spikes and sharp waves were counted and averaged to a value per minute, and each quadrant was assigned a score. MRI and EEG findings were compared in each patient. The presence of a cyst-like tuber in a quadrant correlated with a higher incidence of epileptiform activity in the same quadrant (p = 0.002). This finding supports the notion that cyst-like cortical tubers may contribute to the more severe epilepsy profile seen in TSC patients with these lesions. Quadrants containing greatest tuber burden, largest tubers, and calcified tubers were not predictive of regional interictal epileptiform activity. Furthermore, quadrants without any apparent tuber co-registered with interictal epileptiform discharges in two patients, suggesting a multifactorial component of epileptogenicity in TSC.

Data used in this analysis came from two CRT studies: Cardiac Resynchronization Therapy Registry Evaluating Patient Response with RENEWAL Family Devices (CRT RENEWAL) (n = 436) and Heart Failure-Heart Rate Variability (HF-HRV) (n = 838). Patients from CRT RENEWAL were used to create a model for risk of death using logistic regression and to create a scoring system that could be used to predict mortality. Results of both the logistic regression and the clinical risk score were validated in a cohort of patients from the HF-HRV study. Diagnostics significantly improved over time post-CRT implant (all P < 0.001) and were correlated with a trend of decreased risk of death. The regression model classified CRT RENEWAL patients into low (2.8%), moderate (6.9%), and high (13.8%) risk of death based on tertiles of their model predicted risk. The clinical risk score classified CRT RENEWAL patients into low (2.8%), moderate (10.1%), and high (13.4%) risk of death based on tertiles of their score. When both the regression model and the clinical risk score were applied to the HF-HRV study, each was able to classify patients into appropriate levels of risk. Device diagnostics may be used to create models that predict the risk of death. C1 [Singh, Jagmeet P.] Harvard Univ, Massachusetts Gen Hosp, Sch Med, Cardiac Arrhythmia Serv, Boston, MA 02114 USA.

TI In vivo myocardial distribution of multipotent progenitor cells following intracoronary delivery in a swine model of myocardial infarction SO EUROPEAN HEART JOURNAL LA English DT Article DE In vivo; Multipotent progenitor cells; Intracoronary; Myocardial infarction; Near-infrared fluorescence ID MESENCHYMAL STEM-CELL; LEFT-VENTRICULAR FUNCTION; TRANSCORONARY TRANSPLANTATION; CARDIAC REPAIR; THERAPY; INJECTION; TRACKING; TISSUE; TRIAL; AMI AB Aims There are few data comparing the fate of multipotent progenitor cells (MPCs) used in cardiac cell therapy after myocardial infarction (MI). To document in vivo distribution of MPCs delivered by intracoronary (IC) injection. Methods and results Using an anterior MI swine model, near-infrared (NIR) fluorescence was used for in vivo tracking of labelled MPCs [mesenchymal stromal (MSCs), bone marrow mononuclear (BMMNCs), and peripheral blood mononuclear (PBMNCs)] cells early after IC injection. Signal intensity ratios (SIRs) of injected over non-injected (reference) zones were used to report NIR fluorescence emission. Following IC injection, significant differences in mean SIR were documented when MSCs were compared with BMMNCs [1.28 +/- 0.10 vs. 0.77 +/- 0.11, P < 0.001; 95% Cl (0.219, 0.805), respectively] or PBMNCs [1.28 +/- 0.10 vs. 0.80 +/- 0.14, P = 0.005; 95% Cl (0.148, 0.813), respectively]. Differences were maintained during the 60 min tracking period, with only the MSC-injected groups continuously emitting NIR fluorescence (SIR>1). This is correlated with greater cell retention for MSCs relative to mononuclear cells. However, there was evidence of MSC-related vessel plugging in some swine. Conclusion Our in vivo NIR fluorescence findings suggest that MPC distribution and retention immediately after intracoronary delivery vary depending on cell population and could potentially impact the clinical efficacy of cardiac cell therapy.

It is therefore prudent to utilize all possible information contained in a genome-wide scan. We propose a straightforward analytical approach that tests often unused SNP data without sacrificing statistical validity. We simulate genotype miscalls under a variety of models consistent with observed miscall rates and test for departures from HWE using the standard Pearson's chi(2)-test. We find that true disease susceptibility loci subjected to various patterns of genotype miscalls can be largely out of HWE and, thus, be candidates for removal before association testing. These loci, we demonstrate, can maintain sufficient statistical power even under extreme error models. We additionally show that random miscalls of null SNPs, independent of the phenotype, do not induce bias in case-control or cohort studies, and we suggest that a significant HWE test should not prevent a SNP from being tested when conducting genome-wide association studies in these scenarios. However, association findings for SNPs that are out of HWE must be treated more carefully than 'regular' findings, for example, by re-genotyping the SNP in the same study using a different genotyping technology.

There were numerous changes in the brain spectra that were brain region dependent. At early time points starting around 80 days of age there were increases in brain glutamate. At later time points there were more extensive changes including decreased N-acetyl aspartate and glutamate and increased glutamine, taurine and myo-inositol. The effects of the disease were most severe in spinal cord followed by medulla and then sensorimotor cortex. There were no changes noted in cerebellum as a control region. The effects of creatine supplementation in the diet (2%) were measured in wild-type and FALS animals in medulla, cerebellum and cortex. The increase in brain creatine was largest in cerebellum (25%) followed by medulla (11%) and then cortex (4%), reflecting the ordering of creatine kinase activity. There was a protective effect of creatine on N-acetyl aspartate loss in the medulla at late stages. Creatine supplementation had a positive effect on weight retention, leading to a 13% increase in weight between 120 and 130 days. MRS shows promise in monitoring multiple facets of neuroprotective strategies in ALS and ALS models.

Materials and methods Measurements of mesiodistal, buccolingual size and height of the crowns of primary molars were studied. A transversally descriptive design was carried out and the interrelationship between these three dimensions was established. A sample of 703 first and second primary molars was selected from healthy Spanish boys and girls from 4 to 9 years old. Molars presenting anomalies of the crowns, caries or restorations were excluded. Measurements were made on dental plaster models, using a vernier caliper Descriptive statistics and Pearson correlation coefficient was obtained and Wilcoxon's non-parametric test was applied for comparison of the mean, analysis of sexual dimorphism and comparison of antimeric teeth. Results Average sizes of each group of molars were obtained. Sexual dimorphism was studied utilizing the Wilcoxon test. A variability of relationship between the measurements was found in each molar studied. Primary second molars had less variability than first molars in the three measurements obtained. The measurement with the least variability was height, followed by mesiodistal size. Conclusions Measurements of primary molars showed that average sizes of boys' molars were significantly larger than those of girls. Relationship between the three measurements studied was variable but second molars showed less variability than first molars. The relationship between height and width was found significant in most of the molars. C1 [Barberia, E.; Suarez, M. C.; Maroto, M.] Univ Complutense Madrid, Fac Dent, E-28040 Madrid, Spain.

Thirty-five patients (seven women; mean age 62 +/- 8 years) underwent both CTCA and CCA. CTCA was performed with a second-generation dual-source CT system permitting data acquisition at an HP of 3.4. Patients with heart rates > 60 bpm were excluded from study enrolment. All coronary segments were evaluated by two blinded and independent observers with regard to image quality on a four-point scale (1: excellent to 4: non-diagnostic) and for the presence of significant coronary stenoses (defined as diameter narrowing exceeding 50%). CCA served as the standard of reference. Radiation dose values were calculated using the dose-length product. Diagnostic image quality was found in 99% of all segments (455/459). Non-diagnostic image quality occurred in a single patient with a sudden increase in heart rate immediately before and during CTCA. Taking segments with non-evaluative image quality as positive for disease, the sensitivity, specificity and positive and negative predictive values were 94, 96, 80 and 99% per segment and 100, 91, 88 and 100% per patient. The effective radiation dose was on average 0.9 +/- 0.1 mSv. In patients with heart rates a parts per thousand currency sign60 bpm, CTCA using the HP mode of the dual-source CT system is associated with high diagnostic accuracy for the assessment of coronary artery stenoses at sub-milliSievert doses.

Objective: To describe an anatomic, reproducible technique of bladder neck preservation (BNP) and associated perioperative and long-term outcomes. Design, settings, and participants: From September 2005 to May 2009, data from 619 consecutive RALP were prospectively collected and compared on the basis of bladder neck dissection technique with 348 BNP and 271 standard technique (ST). Surgical procedure: RALP with BNP. Measurements: Tumor characteristics, perioperative complications, and postoperative urinary control were evaluated at 4, 12 and 24 months using (1) the Expanded Prostate Cancer Index (EPIC) urinary function scale scored from 0-100; and (2) continence defined as zero pads per day. Results and limitations: Mean age for BNP versus ST was 57.1 +/- 6.6 yr versus 58.9 +/- 6.7 yr (p = 0.033), while complication rates did not vary significantly by technique. Estimated blood loss was 183.7 +/- 95.8 ml versus 224.6 +/- 108 ml (p = 0.938) in men who underwent BNP versus ST. The overall positive margin rate was 12.8%, which did not differ at the prostate base for BNP versus ST (1.4% vs. 2.2%, p = 0.547). Mean urinary function scores for BNP versus ST at 4, 12, and 24 mo were 64.6 versus 57.2 (p = 0.037), 80.6 versus 79.0 (p = 0.495), and 94.1 versus 86.8 (p < 0.001). Similarly, BNP versus ST continence rates at 4, 12, and 24 mo were 65.6% versus 26.5% (p < 0.001), 86.4% versus 81.4% (p = 0.303), and 100% versus 96.1% (p = 0.308). Conclusions: BNP versus ST is associated with quicker recovery of urinary function and similar cancer control. (C) 2009 European Association of Urology. Published by Elsevier B. V.

TI Comparative Assessment of Antimicrobial Activities of Antibiotic-Treated Penile Prostheses SO EUROPEAN UROLOGY LA English DT Article DE Infection; Minocycline; Penile implant; Rifampin; Vancomycin ID STAPHYLOCOCCUS-AUREUS INFECTION; CENTRAL VENOUS CATHETERS; IN-VIVO EFFICACY; REVISION SURGERY; COLONIZATION; MULTICENTER; PREVENTION; IMPLANTS; DEVICE; MINOCYCLINE AB Background: Although infections associated with penile implants are relatively infrequent, they result in serious medical consequences. Because treatment of these infections usually requires removal of the infected penile implant, prevention of infection is crucial. Since bacterial colonization of the implant is a prelude to clinical infection, antimicrobial modification of the devices may inhibit device colonization and subsequent infection. Objective: We compared the spectrum and durability, both in vitro and in vivo, of two antibiotic-treated penile prostheses: InhibiZone implants pre-impregnated with minocycline and rifampin (M/R) and Titan implants dipped in vancomycin. Design, setting, and participants: 1 x 1-cm cylinder segments of (1) control untreated, (2) M/R-impregnated, and (3) vancomycin-dipped implants were studied. Baseline zones of inhibition (ZI) were determined against clinical isolates, including methicillin-resistant Staphylococcus aureus (MRSA), methicillin-resistant S. epidermidis (MRSE), vancomycin-resistant Enterococcus (VRE), and Escherichia coli. In addition, ZI against methicillin-susceptible S. aureus were compared both in vitro after being washed in a flow chamber and after subcutaneous implantation in rabbits for 1, 2, 7, and 14 d. Measurements: ZI were measured as the diameter of the clear zone around each test device minus the external diameter of the device. Results and limitations: Implants pre-impregnated with M/R displayed a broader spectrum of antimicrobial activity than vancomycin-dipped implants against both gram-positive and-negative bacteria. The M/R-impregnated devices also yielded significantly larger zones of inhibition against S. aureus than vancomycin-dipped implants, both in vitro (p < 0.003) and in vivo throughout the 14-d period of device implantation in rabbits (p <= 0.03). Conclusions: Penile prostheses impregnated with M/R have a broader spectrum in vitro and a more durable antimicrobial activity in vitro and in an animal model than implants dipped in vancomycin. Therefore, along with being a more practical model for incorporating antimicrobials onto the device, the use of implants pre-impregnated with M/R may help reduce the incidence of penile implant infection.

TI Brain fMRI Reactivity to Smoking-Related Images Before and During Extended Smoking Abstinence SO EXPERIMENTAL AND CLINICAL PSYCHOPHARMACOLOGY LA English DT Article DE abstinence; addiction; caudate nucleus; fMRI; nicotine AB Reactivity to smoking-related cues may play a role in the maintenance of smoking behavior and may change depending on smoking status. Whether smoking cue-related functional MRI (fMRI) reactivity differs between active smoking and extended smoking abstinence states currently is unknown. We used fMRI to measure brain reactivity in response to smoking-related versus neutral images in 13 tobacco-dependent subjects before a smoking cessation attempt and again during extended smoking abstinence (52 +/- 11 days) aided by nicotine replacement therapy. Prequit smoking cue induced fMRI activity patterns paralleled those reported in prior smoking cue reactivity fMRI studies. Greater fMRI activity was detected during extended smoking abstinence than during the prequit assessment subcortically in the caudate nucleus and cortically in prefrontal (BA 6, 9, 44, 46), primary somatosensory (BA 1, 2, 3), temporal (BA 22, 41, 42), parietal (BA 7, 40) anterior cingulate (BA 24, 32), and posterior cingulate (BA 31) cortex. These data suggest that during extended smoking abstinence, fMRI reactivity to smoking versus neutral stimuli persists in brain areas involved in attention, somatosensory processing, motor planning, and conditioned cue responding. In some brain regions, fMRI smoking cue reactivity is increased during extended smoking abstinence in comparison to the prequit state, which may contribute to persisting relapse vulnerability.

Using a high-density microelectrode array, we examined the extracellularly recorded responses of rabbit retinal ganglion cells to a bar-shaped electrode array that was stepped at 50 gm increments at different rates across the retina and compared these respons2es to the responses generated to a similarly shaped light stimulus that was stepped across the retina. When the retina was stimulated at 1 step/s, retinal ganglion cells gave robust bursts of action potentials to both the electrode array and the light stimulus. The responses to the 'moving' electrode array decreased progressively with increasing stepping frequency. At 16 steps/s (highest frequency tested), the number of spikes per sweep and the number of bursts per sweep were reduced 75% and 67% respectively. In contrast, when the retina was stimulated at 16 steps/s with the 'moving' light stimulus, the number of spikes per sweep and the number of bursts per sweep were reduced only 43% and 25% respectively. These findings suggest that simple translation of object motion to sequential stimulation through neighboring electrodes may not be the best way to convey the perception of object motion in a patient with a retinal prosthesis.

We show that a short 24-amino acid C-terminal peptide of MGF (MGF24) upregulates heme oxygenase-1 (HO-1) expression and protects SH-SY5Y cells against apoptosis and cell loss induced by three DA cell-specific neurotoxins: 6-hydroxydopamine (6-OHDA), 1-methyl-4-phenylpyridinium (MPP(+)), and rotenone. MGF24 maintains the mitochondrial membrane potential and blocks the release of mitochondrial apoptotic-inducing factor into the cytoplasm induced by 6-OHDA, MPPI, and rotenone. Chemical inhibition of HO-1 with zinc protoporphyrin-IX prevents neuroprotection by MGF24 against the three neurotoxins. MGF24 does not activate Akt signaling nor does Akt inhibition block MGF24 protection of SH-SY5Y cells. In 6-OHDA-lesioned rats, central or peripheral MGF24 administration protects against the development of contralateral forelimb under-utilization, reduces ipsilateral nigral DA cell body loss, and attenuates tyrosine hydroxylase fiber loss in the ipsilateral striatum, independent of IGF-1 receptor activation. Peripheral MGF24 administration upregulates HO-1 expression in striatal and midbrain tissue. This report is the first to demonstrate that a small peptide, MGF24, upregulates HO-1, an important cell defense mediator, and protects DA cells, suggesting new strategies for neuroprotection in Parkinson's disease.

We report the results of a survey of 47 unaffected, mutation positive individuals regarding insurance outcomes. Participants recruited from six different Cancer Risk Programs across the country were queried about their experiences with health, life, and disability insurance, as well as employment issues. Eighty-seven percent of participants carried a BRCA mutation and 87% were part of a group insurance plan at the time of testing. Forty-seven percent of participants self-paid for testing. Less than 10% of participants reported that their results were placed in the general medical record, while 43% did not know where their results were placed. Due to concerns about GD, 13% of participants stated they avoided changing jobs. Thirteen percent stated that their at-risk relatives had not undergone testing for the familial mutation due to fears about GD. Adverse events following genetic testing included two denials from private health insurers, one denial for average life insurance coverage and one denial for additional disability insurance. There were no reports of job discrimination. Results suggest fear of GD is prevalent, yet data do not support evidence that GD exists.

The neural mechanisms of how visual categories become well-established are largely unknown. Studies of initial category learning implicate a network of regions that include inferior temporal cortex (ITC), medial temporal lobe (MTL), basal ganglia (BG), premotor cortex (PMC) and prefrontal cortex (PFC). However, how these regions change with extended learning is poorly characterized. To understand the neural changes in the transition from initially learned to well-practiced categorization, we used functional MRI and compared brain activity and functional connectivity when subjects performed an initially learned categorization task (100 trials of training) and a well-practiced task (4250 trials of training). We demonstrate that a similar network is implicated for initially learned and well-practiced categorization. Additionally, connectivity analyses reveal an increased coordination between ITC, MTL, and PMC when making category judgments during the well-practiced task. These results suggest that category learning involves an increased coordination between a distributed network of regions supporting retrieval and representation of categories.

We pooled data to measure the psychometric properties of IBS end points, including binary responses (eg, "adequate relief') and 50% improvement in symptom severity. METHODS: We pooled data from 12 IBS drug trials involving 10,066 participants. We tested the properties of binary response and 50% improvement end points, including the impact of baseline severity on performance, and measured construct validity using clinical anchors. RESULTS: There were 9044 evaluable subjects (age, 44 years; 85% female; 58% IBS constipation-prominent [IBS-C]; 31% IBS diarrhea-prominent [IBS-D]). Using the binary end point, the proportion responding in the mild, moderate, and severe groups was 42%, 40%, and 38%, respectively (P = .0008). There was no effect of baseline severity on binary response (odds ratio [OR], 0.99; 95% confidence interval [01, 0.99-1.0; P = .07). The proportions reaching 50% improvement in pain were 45%, 41%, and 41%, respectively; there was a small, yet significant, impact of baseline severity (OR, 1.04; 95% CI, 1.03-1.05; P < .0001) that did not meet clinical relevance criteria. Both end points revealed strong construct validity and detected "minimally clinically important differences" in symptoms. Both provided better discriminant spread in IBS-D than IBS-C. CONCLUSIONS: Both the traditional binary and 50% improvement end points are equivalent in their psychometric properties. Neither is impacted by baseline severity, and both demonstrate excellent construct validity. They are optimized for the IBS-D population but also appear valid in IBS-C.

An EAL is thought to predispose individuals to develop a range of chronic illnesses by inducing persistent changes in the central stress response systems, including the hypothalamic-pituitary-adrenal (HPA) axis. We sought to determine if EALs affect the HPA axis response to a visceral stressor in irritable bowel syndrome (IBS) patients and healthy controls, and to determine if this is affected by sex or related to symptoms or quality of life. METHODS: Forty-four IBS patients (25 women, 19 men) and 39 healthy controls (21 women, 18 men) were assessed for gastrointestinal and psychological symptoms and EALs by validated questionnaires and interview. All subjects underwent a visceral stressor (sigmoidoscopy). Salivary cortisol was collected at baseline and serially for I hour poststressor. RESULTS: Twenty-one IBS patients and 18 controls had EALs. In subjects with and without IBS, an EAL was associated with higher mean (+/-SD) cortisol levels (0.32 +/- 0.2 vs 0.20 +/- 0.1 mu g/dL, P = .003) and higher area under the curve (28.1 +/- 17 vs 18.6 +/- 13 mu g x min/dL; P = .005) after the stressor compared with subjects without EALs. In IBS, a faster resolution of cortisol to basal values corresponded to lower symptom severity (r = -0.36, P < .05) and better disease-specific quality of life (r = 0.33, P < OS). CONCLUSIONS: HPA axis hyperresponsiveness to a visceral stressor is related more to a history of EALs than to the presence of IBS. However, HPA axis reactivity has a moderating effect on IBS symptoms.

CA HALT-C Trial Grp TI Effect of HCV RNA Suppression During Peginterferon Alfa-2a Maintenance Therapy on Clinical Outcomes in the HALT-C Trial SO GASTROENTEROLOGY LA English DT Article ID CHRONIC HEPATITIS-C; LOW-DOSE PEGINTERFERON; ADVANCED FIBROSIS; PLUS RIBAVIRIN; COMPENSATED CIRRHOSIS; LIVER-TRANSPLANTATION; VIROLOGICAL RESPONSE; VIRUS-INFECTION; INTERFERON; TELAPREVIR AB BACKGROUND & AIMS: The Hepatitis C Antiviral Long-term Treatment Against Cirrhosis (HALT-C) trial demonstrated that low-dose peginterferon maintenance therapy was ineffective in preventing clinical outcomes in patients with chronic hepatitis C, advanced fibrosis, and failure to achieve a sustained virologic response during lead-in phase treatment with standard dose peginterferon/ribavirin. This analysis was performed to determine whether suppressing HCV RNA during the trial was associated with a reduction in clinical outcomes. METHODS: Seven hundred sixty-four patients treated during the lead-in phase of HALT-C trial were randomized to either peginterferon alfa-2a (90 mu g/week) maintenance therapy or no treatment (control) for 3.5 years. Clinical outcomes included an increase in Child-Turcotte-Pugh score, ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, variceal hemorrhage, hepatocellular carcinoma, and mortality. RESULTS: During the lead-in, >= 4 log(10) decline in serum HCV RNA occurred in 178 patients; 82% of whom lost detectable HCV RNA and later broke through or relapsed. These patients had significantly (P = .003) fewer clinical outcomes whether randomized to maintenance therapy or control. Following randomization, serum HCV RNA increased significantly in all 90 control patients and in 58 of 88 receiving maintenance therapy. Only 30 patients had persistent suppression of HCV RNA by >= 4 log(10) during maintenance therapy. No significant reduction in clinical out-comes was observed in these patients. CONCLUSIONS: Viral suppression by >= 4 log(10) with full-dose peginterferon/ribavirin is associated with a significant reduction in clinical outcomes. Continuing low-dose peginterferon maintenance therapy, even in patients with persistent viral suppression, does not lead to a further decline in clinical outcomes.

Few tests of the integrity of these closures have been Objective: To determine whether a gastrotomy can he closed safely and effectively from within the stomach by using looped T-anchors-a novel, endoscopically placed device. Design: Head-to-head comparison trial of 2 closure methods in 9 explanted porcine stomachs. Setting: Animal laboratory. Intervention: Paired gastrotomies were made in porcine explants. One Was closed by using endoscopic clips and the other was closed by using modified T-anchors in a purse-string fashion. Main Outcome Measurements: Gastric transmural pressure gradients at bursting of these closures were measured while, the explanted Stomachs were inflated with a high-pressure insufflator. Results: vie mean burst pressure of the looped T-anchors was 27.3 mm Hg, whereas that of the clip closures was 14 mm Hg. By using 10 mm Hg as a threshold for a "secure" closure, 7 of 9 clip closures failed to meet the threshold value, whereas all 9 of the T-anchor closures met or exceeded the threshold value (P = .0023, 2-tailed fisher exact test). Limitation: Nonsurvival study. Conclusion: Looped T-anchors provide a secure gastric closure for natural Orifice and are superior to endoscopic clips for this purpose.

Several factors can influence the overall effectiveness of oHSV tropism, including HSV-1 receptor expression, extracellular matrix milieu and cellular permissiveness. We have taken advantage of human prostate organ cultures derived from radical prostatectomies to investigate oHSV tropism. In this study, we show that both G47 Delta and G207 specifically replicate in epithelial cells of the prostatic glands but not in the surrounding stroma. In contrast, both the epithelial and stromal cell compartments were readily infected by wild-type HSV-1. Analysis of oHSV replication in prostate surgical specimens 3 days post infection showed that G47 Delta generated similar to 30-fold more viral progeny than did G207. This correlated with the enhanced expression of G47 Delta-derived glycoprotein gB protein levels as compared with G207. In benign prostate tissues, G207 and G47 Delta titers were notably reduced, whereas strain F titers were maintained at similar levels compared with prostate cancer specimens. Overall, our results show that these oncolytic herpes vectors show both target specificity and replication competence in human prostate cancer specimens and point to the utility of using human prostate organ cultures in assessing oHSV tropism and cellular specificity.

To explore this question, we analyzed the consequences of conditional Dicer1 mutation (Dicer1 "floxed" or Dicer1(fl)) on several mouse models of cancer. Here we show Dicer1 functions as a haploinsufficient tumor suppressor gene. Deletion of a single copy of Dicer1 in tumors from Dicer1(fl/+) animals led to reduced survival compared with controls. These tumors exhibited impaired miRNA processing but failed to lose the wild-type Dicer1 allele. Moreover, tumors from Dicer1(fl/fl) animals always maintained one functional Dicer1 allele. Consistent with selection against full loss of Dicer1 expression, enforced Dicer1 deletion caused inhibition of tumorigenesis. Analysis of human cancer genome copy number data reveals frequent deletion of DICER1. Importantly, however, the gene has not been reported to undergo homozygous deletion, suggesting that DICER1 is haploinsufficient in human cancer. These findings suggest Dicer1 may be an important haploinsufficient tumor suppressor gene and, furthermore, that other factors controlling miRNA biogenesis may also function in this manner.

TI Identification of Novel Genes That Mediate Innate Immunity Using Inbred Mice SO GENETICS LA English DT Article ID WHOLE-GENOME ASSOCIATION; TOLL-LIKE RECEPTORS; SALMONELLA-ENTERITIDIS; INFLAMMATORY RESPONSE; POPULATION-STRUCTURE; CONGENIC STRAINS; HUMAN-DISEASE; LOCI; LIPOPOLYSACCHARIDE; PERSISTENCE AB Innate immunity is the first line of defense against microbial infections. Although polymorphisms in toll-like receptors (TLRs) and downstream signaling molecules (CD14, TLR2, TLR4, TLR5, and IRAK4) affect the innate immune response, these variants account for only a portion of the ability of the host to respond to bacteria, fungi, and viruses. To identify other genes involved in the innate immune response, we challenged 16 inbred murine strains with lipopolysaccharide (LPS) systemically and measured serum concentrations of pro-inflammatory cytokines IL-1 beta, IL-6, and TNF alpha, and the chemokine KC 6 hr post-treatment. Loci that segregate with strain phenotypes were identified by whole genome association (WGA) mapping of cytokine concentrations. Published gene expression profiles and quantitative trait loci (QTL) were then utilized to prioritize loci and genes that potentially regulate the host response to LPS. Sixteen loci were selected for further investigation by combining WGA analysis with previously published QTL for murine response to LPS or gram negative bacteria. Thirty-eight genes within these loci were then selected for further investigation on the basis of the significance of the identified locus, transcriptional response to LPS, and biological plausibility. RNA interference-mediated inhibition of 4 of 38 candidate genes was shown to block the production of IL-6 in J774A.1 macrophages. In summary, our analysis identified 4 genes that have not previously been implicated in innate immunity, namely, 1110058L19Rik, 4933415F23Rik, Fbxo9, and Ipo7. These genes could represent potential sepsis biomarkers or therapeutic targets that should be further investigated in human populations.

The MGC cloning effort initially relied on random expressed sequence tag screening of cDNA libraries. Here, we summarize our recent progress using directed RT-PCR cloning and DNA synthesis. The MGC now contains clones with the entire protein-coding sequence for 92% of human and 89% of mouse genes with curated RefSeq (NM-accession) transcripts, and for 97% of human and 96% of mouse genes with curated RefSeq transcripts that have one or more PubMed publications, in addition to clones for more than 6300 rat genes. These high-quality MGC clones and their sequences are accessible without restriction to researchers worldwide.

Approximately two-thirds of the ORFeome has been verified reactively by amplifying and cloning computationally predicted transcript models; still a full third of the ORFeome remains experimentally unverified. To fully identify the protein-coding potential of the worm genome including transcripts that may not satisfy existing heuristics for gene prediction, we developed a computational and experimental platform adapting rapid amplification of cDNA ends (RACE) for large-scale structural transcript annotation. We interrogated 2000 unverified protein-coding genes using this platform. We obtained RACE data for approximately two-thirds of the examined transcripts and reconstructed ORF and transcript models for close to 1000 of these. We defined untranslated regions, identified new exons, and redefined previously annotated exons. Our results show that as much as 20% of the C. elegans genome may be incorrectly annotated. Many annotation errors could be corrected proactively with our large-scale RACE platform.

TI Gliadin-primed CD4+CD45RBlowCD252-T cells drive gluten-dependent small intestinal damage after adoptive transfer into lymphopenic mice SO GUT LA English DT Article ID REGULATORY T-CELLS; CELIAC-DISEASE; IMMUNODEFICIENT MICE; TRANSGENIC MICE; COLITIS; TOLERANCE; ANTIGEN; ACTIVATION; EXPANSION; MODEL AB Background and aims: Coeliac disease is a common small intestinal inflammatory disorder that results from a breach of intestinal tolerance to dietary gluten proteins, driven by gluten-reactive effector T cells. We aimed to assess the pathogenic role of gluten-reactive T cells and to generate a model of gluten-induced enteropathy. Methods: CD4+CD252 T cell fractions were adoptively transferred into lymphopenic mice, leading to "baseline" small intestinal inflammation. Results: Rag1-/- recipients of gliadin-presensitised CD4+CD45RBlowCD252- T cells, but not CD4+CD45RBhigh naive T cells, gained less weight and suffered from more severe duodenitis when challenged with oral gluten than recipients on gluten-free diet, or recipients of control (ovalbumin)-presensitised T cells. This was accompanied by deterioration of mucosal histological features characteristic of coeliac disease, and increased Th1/Th17 cell polarisation in the duodenum and the periphery. Interestingly, reintroduction of a gluten-free diet led to weight gain, improvement of histological duodenitis, and a decrease in duodenal interferon c and interleukin 17 transcripts. Moreover, B cell-competent nude recipients of gliadin-presensitised CD4+CD45RBlowCD252- T cells produced high levels of serum anti-gliadin immunoglobulin A (IgA) and IgG1/IgG2c only when challenged with oral gluten. Conclusions: CD4+ T cell immunity to gluten leads to a breach of oral gluten tolerance and small intestinal pathology in lymphopenic mice, similar to human coeliac disease. This model will be useful for the study of coeliac disease pathogenesis, and also for testing novel non-dietary therapies for coeliac disease. C1 [Freitag, T. L.; Junker, Y.; Popov, Y.; Kelly, C.

TI Prognosis and hormone receptor status in older and younger patients with advanced-stage papillary serous ovarian carcinoma SO GYNECOLOGIC ONCOLOGY LA English DT Article DE Ovarian cancer; Age; Elderly; Hormone receptor ID GYNECOLOGIC-ONCOLOGY-GROUP; PROGRESSION-FREE SURVIVAL; PHASE-II; REFRACTORY OVARIAN; CANCER; AGE; CARBOPLATIN; OUTCOMES; THERAPY AB Objective. Prior Studies have Suggested that patients diagnosed with ovarian cancer at an older age have Worse Outcomes. However, few Studies have examined whether differing patterns of protein expression in tumors in older patients correlate with this poorer prognosis. We investigated the correlation of age with prognosis and the significance of hormone receptor status in younger versus older patients through construction of a clinically-annotated high-density tissue microarray (HTMA) composed of stage III and IV papillary serous ovarian cancer cases. Methods. Two cohorts of patients (age >= 65 and <= 55 at diagnosis) were identified retrospectively from ovarian carcinoma pathology cases reviewed at our institution between 1999 and 2005. An HTMA was Constructed from 148 eligible cases, and clinical data were abstracted through chart and database review. Results. No difference in survival was observed between younger and older patients. Patients >= 70 years had decreased Survival On univariate, but not multivariate, analysis. ER was significantly more likely (p=0.01) and PR significantly less likely (p=0.02) to be expressed in older patients. Neither ER nor PR independently correlated with survival in the overall study population. Conclusions. Patients with advanced-stage papillary serous ovarian cancer >= 65 years of age at diagnosis have a similar Survival as patients <= 55 years. Hormone receptor Status differs significantly between the two age groups, and in the Younger patient cohort, there is a trend towards longer overall survival for ER/PR positive tumors. These results suggest that ovarian cancer in younger patients differs biologically front that ill older patients. (C) 2009 Elsevier Inc. All rights reserved.

To estimate the anti-tumor activity of pemetrexed in patients with advanced OF recurrent carcinoma of the endometrium and to determine the nature and degree of toxicity. Methods. A multicenter phase II trial was conducted by the Gynecologic Oncology Group (GOG). Patients must have had advanced or recurrent measurable carcinoma of the endometrium and failed one prior chemotherapy regimen. Pemetrexed at a dose of 900 mg/m(2) was administered as an IV infusion over 10 min every 21 days. Results. From May 1, 2006 to July 31, 2007, 27 patients were entered by 10 member institutions of the GOG with two patients being deemed ineligible. A total of 101 cycles were administered with 28% of patients receiving five or more cycles. Overall, the treatment was well tolerated. More serious toxicities (grade 3 and 4) included anemia in 20%, leukopenia in 40%, neutropenia in 48%, and constitutional in 16%. No treatment-related deaths were reported. One patient (4%) had a partial response. Eleven patients (44%) had stable disease and eleven (44%) patients had increasing disease. Response could not be assessed in two patients (7%). Median progression-free survival was 2.7 months and overall survival was 9.4 months. Conclusion. Pemetrexed has minimal activity in the treatment of recurrent or persistent endometrial carcinoma at the dose and schedule tested. (C) 2009 Elsevier Inc. All rights reserved.

Anatomically realistic models of the pregnant patient representing 3- and 6-mo gestational stages were implemented into the MCNPX code together with a detailed accelerator model that is capable of simulating scattered and leakage radiation from the accelerator head. The phantom was shielded using suggested lead and Cerrobend in different locations and with different thicknesses. Absorbed doses to the fetus both with and without shielding were calculated considering typical mantle, head and neck, and brain treatment plans. The unshielded fetal doses tended to increase with decreasing distance from the field edge to the nearest fetal point and increasing of the field size.. The unshielded absorbed doses to the fetus for all treatment plans ranged from a maximum of 4.08 mu Gy/MU (monitor unit) to a minimum 0.09 mu Gy/MU. The use of lead or Cerrobend shielding reduced the fetal doses by factors of up to 4. For an optimal shield half-value layer, the dose reduction between lead and Cerrobend was statistically insignificant. The maximum permitted MUs for the mantle treatments with shielding were calculated based on 5 cGy dose limits suggested by TG-36. The study demonstrates an accurate assessing tool that can be used to determine the absorbed dose to the fetus and to design the shielding as part of the treatment planning and risk management.

Discrete-event simulation (DES) is a tool that readily accommodates questions of capacity planning, throughput management and interacting resources. As a result the use of DES in informing healthcare decision making is increasing. However, understanding when and how to build a DES model and use it for policy making is not yet a common knowledge. Methods: The steps in building a DES model will be demonstrated using a real-world example, i.e., pediatric ultrasound screening for hip dysplasia. The main components of a DES model such as entities, resources and queues will be introduced and we will examine questions such as referral schedule, number of ultrasound machines and type of screeners and how these entities interact. Finally a review of the statistical techniques appropriate to DES will be provided. Conclusion: Discrete-event simulation is a valuable tool in the policymakers armentarium. It can be used effectively to analyze and understand complex healthcare systems and policy problems such as population screening. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

TI Hospice Characteristics and the Disenrollment of Patients with Cancer SO HEALTH SERVICES RESEARCH LA English DT Article DE Health care organization; hospice; Medicare hospice benefit ID MARKET-STRUCTURE; CARE; COMPETITION; PATTERNS AB Objective To characterize the types of hospices with higher rates of patient disenrollment from the Medicare Hospice Benefit and the markets in which these hospices operate. Data Source Secondary analyses of Surveillance, Epidemiology and End Results-Medicare data. Analyses included patients who died of cancer from 1998 to 2002 and who used hospice (n=90,826). Study Design We used generalized estimating equations to estimate the association of patient disenrollment with hospice size, years since Medicare certification, ownership, staff mix, competition, urban/rural status, region, and fiscal intermediary. Other covariates included patient demographic and clinical characteristics. Principal Findings Patients were more likely to disenroll from hospice if they were served by newer hospices (OR=1.14; 95 percent CI 1.03, 1.26), by smaller hospices (OR=1.11; 95 percent CI 1.02, 1.20), or by hospices in more competitive markets (OR=1.17; 95 percent CI 1.03, 1.35). There was an independent effect of the hospice's fiscal intermediary on disenrollment, particularly disenrollment after 6 months with hospice (Wald chi 2=21.2, p=.007). Conclusions The reasons for higher disenrollment rates for newer hospices, for smaller hospices, and for hospices in highly competitive markets are likely complex; however, results suggest that there are organizational-level barriers to keeping patients with cancer enrolled with hospice. Variation across fiscal intermediaries may indicate that regulatory oversight, particularly of long-stay patients, influences hospice disenrollment. C1 [Carlson, Melissa D.

These findings were compared with those after implantation of a sirolimus-eluting stent (SES; Cypher Select). Design: Cross-sectional observational study with prospective OCT registry. Setting: Nine months after ZES or SES implantation. Patients and methods: A total of 68 patients (32 ZES and 36 SES) underwent OCT at 9 months after stent implantation. The neointima hyperplasia (NIH) thickness inside each strut and percentage of NIH area at every 1 mm cross section were measured. Main outcome measurement: The degree of neointimal coverage and the prevalence of malapposition at 9 months after ZES and SES implantation using OCT. Results: The mean (SD) NIH thickness (251.2 (110.0) mu m vs 85.5 (53.3) mu m, p < 0.001) and percentage of NIH area (27.9 (9.1)% vs 11.2 (7.1)%, p < 0.001) were significantly greater in ZES than in SES. The prevalence of uncovered strut as well as malapposed strut was significantly lower in ZES than in SES (0.3% vs 12.3%, p < 0.001 and 0.08% vs 2.6%, p < 0.001). Thrombus was not observed in ZES (0.0% in ZES vs 27.8% in SES, p = 0.001). Conclusions: Neointimal coverage in ZES was almost complete and malapposition was very rare at 9-months' follow-up.

Initial enthusiasm, based on strong pathophysiological rationale and apparent empirical efficacy, has been progressively limited by results of controlled trials and registries showing poorer outcomes of the patients on inotropic therapy. The use of these agents remains, however, potentially indicated in a significant proportion of patients with low cardiac output, peripheral hypoperfusion and end-organ dysfunction caused by heart failure. Limitations of inotropic therapy seem to be mainly related to their mechanisms of action entailing arrhythmogenesis, peripheral vasodilation, myocardial ischemia and damage, and possibly due to their use in patients without a clear indication, rather than to the general principle of inotropic therapy itself. This review will discuss the characteristics of the patients with a potential indication for inotropic therapy, the main data from registries and controlled trials, the mechanism of the untoward effects of these agents on outcomes and, lastly, perspectives with new agents with novel mechanisms of action.

Currently available inotropes, such as dobutamine and milrinone, increase cardiac contractility at the expense of increased intracellular concentrations of calcium and cAMP, contributing to increased heart rate, hypotension, arrhythmias, and mortality. These adverse effects are inextricably linked to their inotropic mechanism of action. A new class of pharmacologic agents, cardiac myosin activators, directly targets the kinetics of the myosin head. In vitro studies have demonstrated that these agents increase the rate of effective myosin cross-bridge formation, increasing the duration and amount of myocyte contraction, and inhibit non-productive consumption of ATP, potentially improving myocyte energy utilization, with no effect on intracellular calcium or cAMP. Animal models have shown that this novel mechanism increases the systolic ejection time, resulting in improved stroke volume, fractional shortening, and hemodynamics with no effect on myocardial oxygen demand, culminating in significant increases in cardiac efficiency. A first-in-human study in healthy volunteers with the lead cardiac myosin activator, CK-1827452, as well as preliminary results from a study in patients with stable chronic heart failure, have extended these findings to humans, demonstrating significant increases in systolic ejection time, fractional shortening, stroke volume, and cardiac output. These studies suggest that cardiac myosin activators offer the promise of a safe and effective treatment for heart failure. A program of clinical studies are being planned to test whether CK-1827452 will fulfill that promise. C1 [Teerlink, John R.] San Francisco VA Med Ctr, San Francisco, CA 94121 USA.

Vasodilators are one of the cornerstones of AHF management; however, to a large extent, none of those currently used has been examined by large, placebo-controlled, non-hemodynamic monitored, prospective randomized studies powered to assess the effects on outcomes, in addition to symptoms. In this article, we will discuss the role of vasodilators in AHF trying to point out which are the potentially best indications to their administration and which are the pitfalls which may be associated with their use. Unfortunately, most of this discussion is only partially evidence based due to lack of appropriate clinical trials. In general, we believe that vasodilators should be administered early to AHF patients with normal or high blood pressure (BP) at presentation. They should not be administered to patients with low BP since they may cause hypotension and hypoperfusion of vital organs, leading to renal and/or myocardial damage which may further worsen patients' outcome. It is not clear whether vasodilators have a role in either patients with borderline BP at presentation (i.e., low-normal) or beyond the first 1-2 days from presentation. Given the limitations of the currently available clinical trial data, we cannot recommend any specific agent as first line therapy, although nitrates in different formulations are still the most widely used in clinical practice.

It is now recognized that immune thrombocytopenic purpura (ITP) is a disorder of reduced platelet production as well as increased platelet destruction. New therapies for ITP have emerged that have exploited this new pathophysiologic understanding.

Previous morphometric studies of large cohorts of patients with treatment refractory chronic hepatitis C have shown a mean increase in fibrosis of 30% to 58% in 1 year. The aim of the present study was to quantify fibrosis progression in biopsy specimens obtained over 1.5 to 44 5 years from three groups of patients with baseline bridging fibrosis or cirrhosis (Ishak stages 3-6) enrolled in the Hepatitis C Antiviral Long-term Treatment Against Cirrhosis Trial. The main group of 346 lead-in nonresponders (viremic after 24 weeks of peginterferon-ribavirin therapy) had a mean fibrosis increase of 61% over pretreatment baseline after 2 years and 80% after 4 years. In contrast, the 78 breakthrough/relapse patients (undetectable serum hepatitis C virus RNA after 24 weeks of peginterferon-ribavirin and receiving antiviral therapy for 48 weeks) showed a mean increase in fibrosis of 48% when biopsied 36 months from pretreatment baseline but no further increase at 60 months. Finally, the 111 express patients with baseline biopsies following unsuccessful peginterferon-ribavirin outside the trial had significantly more baseline fibrosis than the others but an increase of only 21% after 21 months and a slight decrease at 45 months. Maintenance therapy with low-dose peginterferon had no effect on fibrosis changes in any of the groups. Conclusion: Morphometry demonstrated complex, nonlinear changes in fibrosis over time in this heterogeneous cohort of patients with interferon-refractory chronic hepatitis C.

Radical surgery (including liver resection and regional lymphadenectomy) is applied for some gallbladder cancers, but the benefits of these procedures are unproven. For patients with T1b cancers discovered incidentally on cholecystectomy specimens, the utility of radical surgery remains debated. Methods: A decision analytic Markov model was created to estimate and compare life expectancy associated with management strategies for a simulated cohort of patients with incidentally discovered T1b gallbladder cancer after routine cholecystectomy. In one strategy, patients were treated with no additional surgery; in another, patients were treated with radical resection. The primary (base-case) analysis was calculated based on a cohort of 71-year-old females and incorporated best available input estimates of survival and surgical mortality from the literature. Sensitivity analysis was performed to assess the effects of model uncertainty on outcomes. Results: In the base-case analysis, radical resection was favoured over no further surgical resection, providing a survival benefit of 3.43 years for patients undergoing radical resection vs. simple cholecystectomy alone. Sensitivity analysis on the age at diagnosis demonstrated that the greatest benefit in gained life-years was achieved for the youngest ages having radical resection, with this benefit gradually decreasing with increasing age of the patient. High peri-operative mortality rates (>= 36%) led to a change in the preferred strategy to simple cholecystectomy alone. Conclusions: Decision analysis demonstrates that radical resection is associated with increased survival for most patients with T1b gallbladder cancer.

TI Alterations in Functional Activation in Euthymic Bipolar Disorder and Schizophrenia During a Working Memory Task SO HUMAN BRAIN MAPPING LA English DT Article DE bipolar; schizophrenia; working memory; executive function; fMRI; dorsolateral prefrontal cortex ID DORSOLATERAL PREFRONTAL CORTEX; RATING-SCALE; NEUROCOGNITIVE FUNCTION; EXECUTIVE FUNCTION; BRAIN IMAGES; FMRI; PERFORMANCE; MRI; DYSFUNCTION; IMPAIRMENT AB Dysfunctions in prefrontal cortical networks are thought to underlie working memory (WM) impairments consistently observed in both subjects with bipolar disorder and schizophrenia. It remains unclear, however, whether patterns of WM-related hemodynamic responses are similar in bipolar and schizophrenia subjects compared to controls. We used fMRI to investigate differences in blood oxygen level dependent activation during a WM task in 21 patients with euthymic bipolar 1, 20 patients with schizophrenia, and 38 healthy controls. Subjects were presented with four stimuli (abstract designs) followed by a fifth stimulus and required to recall whether the last stimulus was among the four presented previously. Task-related brain activity was compared within and across groups. All groups activated prefrontal cortex (PFC), primary and supplementary motor cortex, and visual cortex during the WM task. There were no significant differences in PFC activation between controls and euthymic bipolar subjects, but controls exhibited significantly increased activation (cluster-corrected P < 0.05) compared to patients with schizophrenia in prefrontal regions including dorsolateral prefrontal cortex (DLPFC). Although the bipolar group exhibited intermediate percent signal change in a functionally defined DLPFC region of interest with respect to the schizophrenia and control groups, effects remained significant only between patients with schizophrenia and controls. Schizophrenia and bipolar disorder may share some behavioral, diagnostic, and genetic features. Differences in the patterns of WM-related brain activity across groups, however, suggest some diagnostic specificity. Both patient groups showed some regional task-related hypoactivation compared to controls across the brain. Within DLPFC specifically, patients with schizophrenia exhibited more severe WM-related dysfunction than bipolar subjects. Hunt Brain Mapp 30:3958-3969, 2009. (C) 2009 Wiley-Liss, Inc.

A widely-used test of fluid reasoning and intelligence, the RSPM assays abilities to flexibly infer rules, manage goal hierarchies, and perform high-level abstractions. The neural substrates for these abilities are known to encompass a large frontoparietal network, with different processing models placing variable emphasis on the specific roles of the prefrontal or posterior regions. We used functional magnetic resonance imaging to explore the neural bases of autistics' RSPM problem solving. Fifteen autistic and eighteen non-autistic participants, matched on age, sex, manual preference and Wechsler IQ, completed 60 self-paced randomly-ordered RSPM items along with a visually similar 60-item Pattern matching comparison task. Accuracy and response times did not differ between groups in the pattern matching task. In the RSPM task, autistics performed with similar accuracy, but with shorter response times, compared to their non-autistic controls. hi both the entire sample and a subsample of participants additionally matched on RSPM performance to control for potential response time confounds, neural activity was similar in both groups for the pattern matching task. However, for the RSPM task, autistics displayed relatively increased task-related activity in extrastriate areas (BA18), and decreased activity in the lateral prefrontal cortex (BA9) and the medial posterior parietal cortex (BA7). Visual processing mechanisms may therefore play a more prominent role in reasoning in autistics. Hum Brain Mapp 30:4082-4107, 2009. (C) 2009 Wiley-Liss, Inc.

However, a vigorous experimental system to identify an overriding, key effector mediating innate immunity to lung infection has not been utilized. As many of the important components of innate immunity are involved in recruitment and activation of polymorphonuclear neutrophils (PMNs) to infected tissues, we hypothesized that the cells and factors needed for their proper recruitment to the lung comprised the major mediators of innate immunity. In neutropenic mice, intranasal (i.n.) doses of P. aeruginosa as low as 10 to 100 CFU/mouse produced a fatal lung infection, compared with 10(7) to > 10(8) CFU for nonneutropenic mice. There was only a very modest increased mortality in mice lacking mature lymphocytes and no increased mortality in mice depleted of alveolar macrophages when administered i.n. P. aeruginosa. Recombinant mouse granulocyte colony-stimulating factor increased survival of neutropenic mice after i.n. P. aeruginosa inoculation. MyD88(-/-) mice, which cannot recruit PMNs to the lungs, were highly susceptible to fatal P. aeruginosa lung infection, with bacterial doses of < 120 CFU being lethal. Activation of a MyD88-independent pathway for PMN recruitment to the lungs in MyD88(-/-) mice resulted in enhanced protection against P. aeruginosa lung infection. Overall, in the absence of PMNs, mice cannot resist P. aeruginosa lung infection from extremely small bacterial doses. There is an inescapable requirement for local PMN recruitment and activation to mediate innate immunity to P. aeruginosa lung infection.

We developed a decision-analytic computer simulation model to determine the economic value of using such a strategy before all vascular surgical procedures from the societal and third-party payer perspectives at different MRSA prevalence and decolonization success rates. RESULTS. The model showed preoperative MRSA testing to be cost-effective (incremental cost-effectiveness ratio, <$50,000 per quality-adjusted life year) when the MRSA prevalence is >= 0.01 and the decolonization success rate is >= 0.25. In fact, this strategy was dominant (ie, less costly and more effective) at the following thresholds: MRSA prevalence >= 0.01 and decolonization success rate >= 0.5, and MRSA prevalence >= 0.025 and decolonization success rate >= 0.25. CONCLUSION. Testing and decolonizing patients for MRSA before vascular surgery may be a cost-effective strategy over a wide range of MRSA prevalence and decolonization success rates.

We performed a retrospective pre-post study in an urban tertiary-care teaching hospital. Subjects included all patients, ages 2-54, who presented to the ED with asthma or URI from January 1 to July 31 for each of the 3 years before health care reform and for the period after the insurance mandate officially went into effect on January 1, 2008. We used chi-square analysis to compare the frequency of utilization of the ED by uninsured patients before and after the implementation of an individual health insurance mandate in Massachusetts. For the period before the implementation of health reform, an annual average of 301 ED visits for patients with either URI (average n = 131) or asthma (average n = 170) were identified. After health care reform, there were 366 visits found for URI (n = 132) and asthma (n = 234) over a similar time period. There was a statistically significant decrease in ED utilization by the uninsured for URI but not for asthma. As a secondary analysis, visits for patients covered by the uncompensated care pool (UCP) before health care reform was not different from the combined frequency of visits by the remaining uninsured covered by a health safety net pool and those who qualified for the state subsidized Commonwealth Care program after health care reform. In this study, health care reform was associated with a decrease in the number of uninsured patients who presented to the ED with URI but not asthma. This study is limited by its analysis of a single large institution and a limited set of diagnoses.

This article reviews the available empirical data that support or refute the current DSM-IV-TR defined characteristics of a binge episode. Method: A systematic literature review was conducted using Medline/Pubmed electronic database on DSM-IV-TR defined binge characteristics and associated attributes. Results: Data support the current DSM guidelines indicating that binge episodes typically occur in less than 2 h. Size of binge episodes has variability across BN and BED diagnostic groups. Loss of control (LOC) continues to be a core feature of binge eating. Negative affect is the most widely reported antecedent. Strikingly, little is known about binge episodes among individuals with anorexia nervosa-binge/purge subtype. Discussion: Available empirical evidence supports the current DSM duration and LOC attributes of a binge episode in BN and BED. However, a more controversial issues is the extent to which size is important in the definition of a binge episode (e.g., subjective vs. objective episodes) across diagnostic categories and the extent to which binge size informs prognosis, treatment, and clinical outcomes. Further study of binge eating attributes in AN is needed. 02009 American Psychiatric Association.

However, little is known about the relationship of performance in specific cognitive domains to subsequent overall decline. Objective To examine the specific and/or combined contribution of four MMSE domains (orientation for time, orientation for place, delayed recall. and attention) to prediction of overall cognitive decline on the MMSE. Methods Linear mixed models were applied to 505 elderly nursing home residents (mean age = 85, > 12 years education = 27%; 79% F, mean follow-up = 3.20 years) to examine the relationship between baseline scores of these domains and total MMSE scores over time. Results Orientation for time was the only domain significantly associated with MMSE decline over time. Combination of poor delayed recall with either attention or orientation for place was associated with significantly increased decline on the MMSE. Conclusions The MMSE orientation for time predicts overall decline on MMSE scores over time. A good functioning domain added to good functioning delayed recall was associated with slower rate of decline. Copyright (C) 2009 John Wiley Sons. Ltd.

Given these results and the evolution of targeted therapies, there is an increasing need for prognostic and predictive factors to stratify patients for individualized care. Many laboratories have also investigated the specific individual biomarkers correlating them with clinicopathologic characteristics. Unfortunately, the vast majorities of these biomarkers have not proved clinically valuable. In this article, we review published genomic signatures including data generated in Our laboratory for their relevance. Methods: Multiple published expression profiling articles were selected for review and discussion. Genomic Studies were separated from those with dichotomized Survival data and unsupervised analysis to identify discreet subsets of tumors and Studies that generated activated pathways. Results: The identification of prognostic and predictive individual biomarkers has been common. Few of these have been validated. Genomic profiles have been obtained that distinguish short- from long-term survivors. The relevance of these studies to the large number of patients within the extremes remains unclear. Unsupervised Clustering Studies of ovarian cancers have identified potential subsets of tumors that reflect different clinical behavior. These Studies will require large numbers of independent samples for validation. Another approach has been to identify genes that correlate with patient Survival as a continuous variable. These genes are then placed into biologic context using pathway analysis. These pathways provide potential therapeutic targets, and those patients whose tumors express these targets may be most effectively treated by using inhibitors specific for the pathway. Conclusions: There is a major need for prognostic and predictive biomarkers for ovarian cancer. With the development of new genomic technologies, there is ail Opportunity to identify gene expression signatures that can be used to stratify patients according to their ultimate survival and response to chemotherapy. Large independent sets and robust statistical techniques will be required to fully exploit this approach.

Existing studies examining this question have focused on twins. The present study built on the literature by conducting a preliminary study of the heritability of depressive symptoms within extended families. At the same time, this study assessed the need for adjustment of a heritability measure in a family study using a multi-generational sample. The sample consisted of 230 community-dwelling extended families that included 431 adult offspring, comprising full siblings, half siblings and cousins that participated in the University Of Southern California Longitudinal Study of Generations. All participants filled out the Center for Epidemiologic Studies Depression (CES-D) scale. The multilevel analysis allowed us to model the natural hierarchy of the extended family. Results indicate that the proportion of the phenotypic variance for CES-D that occurs due to genetic differences is not significantly larger than zero among these participants [h(2) = 8.6%, 95% conficlence interval (CI) = 0-57%, p = 0.71]. Our findings Suggest that future Studies examining depressive symptoms in this sample can focus on non-genetic explanatory factors without the necessity to control for genetic variation. However, our study may be limited by measurement of prevalent depressive symptoms, which may not generalize to lifetime depressive symptoms. Copyright (C) 2009 John Wiley & Sons, Ltd.

This novel method, termed optimized adiabatic TOtal through Bond correlation SpectroscopY (TOBSY) solid-state NMR pulse sequence for two-dimensional (2D) (1)H-(1)H homonuclear scalar-coupling longitudinal isotropic mixing, was demonstrated to provide a 40-60% improvement in signal-to-noise ratio (SNR) relative to its liquid-state analogue TOCSY (TOtal Correlation SpectroscopY). Using 1-and 2-dimensional HRMAS NMR experiments, we identified several metabolites in burned tissues. Quantification of metabolites in burned tissues showed increased levels of lipid compounds, intracellular metabolites (e.g., taurine and phosphocreatine) and substantially decreased water-soluble metabolites (e.g., glutathione, carnosine, glucose, glutamine/glutamate and alanine). These findings demonstrate that HRMAS NMR Spectroscopy using TOBSY is a feasible technique that reveals new insights into the pathophysiology of burn trauma. Moreover, this method has applications that facilitate the development of novel therapeutic strategies. C1 [Righi, Valeria; Andronesi, Ovidiu; Mintzopoulos, Dionyssios; Tzika, A.

Methods and Materials: We retrospectively analyzed 238 patients with Stage H breast cancer (one to three positive lymph nodes) treated with mastectomy at the Massachusetts General Hospital between 1990 and 2004. The estimates of locoregional recurrence (LRR), disease-free survival (DFS), and overall survival were analyzed according to the delivery of radiotherapy and multiple prognostic factors. Results: LRR and DFS were significantly improved by postmastectomy radiotherapy (PMRT), with a 5- and 10-year LRR rate without PMRT of 6 % and 11 %, respectively and, with PMRT, of 0 % at both 5 and 10 years (p = .02). The 5- and 10-year DFS rate without PMRT was 85 % and 75 %, respectively, and, with PMRT, was 93 % at both 5 and 10 years (p = .03). A similar benefit was found for patients treated with RT to the CW alone. The LRR, DFS, and overall survival rate for patients treated to the CW only was 0 %, 96 %, and 95 % at 10 years, respectively. Conclusion: Our data suggest that adjuvant PMRT to the CW alone provides excellent disease control for patients with breast cancer <5 cm with one to three positive lymph nodes.

The 16S rDNA bacterial genes were PCR-amplified from DNA isolated from the entire hindgut using Bacteria-selective primers, and the 16S rDNA amplicons were cloned into Escherichia coli. The changes in the gut microbiota of Cryptocercus under three physiological conditions, "active," "fasting," and "dead," were studied. Analysis of the active-clone library revealed 45 new phylotypes (clones sharing >97% sequence identity were grouped into the same phylotype) from 54 analyzed clones. The clones were affiliated with the phyla Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria, Spirochaetes, Synergistetes, Verrucomicrobia, and candidate phylum Termite Group I (TG1). Clones belonging to Spirochaetes, Bacteroidetes, and TG1 phyla clustered with previously reported sequences obtained from the guts of several termites, suggesting that these clones are common constituents of the intestinal microbiota of lower termites and Cryptocercus. In the fasting-clone library, 19 new phylotypes, from 49 clones studied, were distinguished. The new phylotypes were affiliated with the phyla Bacteroidetes, Firmicutes, Actinobacteria, Proteobacteria, Spirochaetes, Synergistetes, and the candidate phylum TM7. Finally, in the dead-clone library, 24 new phylotypes from 50 studied clones were found. The new phylotypes were affiliated with the phyla Firmicutes, Actinobacteria, and Proteobacteria. Thus, from active, to fasting, to dead physiological states, a decrease in the number of phyla present in the whole microbial gut was evident. However, in the dead physiological state, each phylum conserved contained more new phylotypes. This poses a taxophysiological paradox, because a stable, active physiological state of Cryptocercus-due to a continuous input of wood-supports a higher diversity of bacterial phyla, probably necessary to maintain a sharp O(2)-H(2) gradient in the gut. By contrast, in the dead state, nutrient input is limited to the residual gut microbiota that is killed by the newly oxic environment, thus providing a food source for other, aerobic or facultative anaerobic bacteria. This results in an increase in the internal diversity of the few remaining phyla.

However, relatively few spirochetes from these microbial mats have been described and characterized. We used 16S rDNA phylogenetic analysis to investigate the spirochetal diversity of microbial mats from two locations ill the western Mediterranean (Ebro Delta, Spain, and Camargue, France). Samples from each location were monitored in the spring and winter over a period of 1 to 2 years. In the sequence analysis of 332 clones derived from samples of both locations, 42 novel phylotypes of not-yet-cultivated spirochetes belonging to the genus Spirochaeta were detected. None of the phylotypes were identified as known culturable species of Spirochaeta or previously identified phylotypes cloned from other hypersaline microbial mat Such as Guerrero Negro, Mexico. Eight of the phylotypes were common to Ebro and Camargue mats, and two (IF058 and LL066) were present both in spring and winter. Some phylotypes appeared to show seasonal variation, i.e., they were found only in the spring, but not in the winter. Ebro and Camargue phylotypes, like phylotypes From Guerrero Negro, grouped according to the vertical gradient of oxygen and sulfide ill the mat. Some phylotypes, Such as LH073, IE028, LH042, or LG013 were harbored in low H(2)S or H(2)S-O(2) interface zone. In contrast, major phylotypes were detected in deeper layers and they were likely strict anaerobes and high tolerant to H(2)S. The presence of spirochetes in differently located microbial mats suggests that they constitute very diverse and stable populations involved in a well-integrated metabolic symbiosis (i.e., permanent physiological cooperation) with other guild Populations in the mats, where they maintain a coordinated functional and stable community [Int Microbiol 2008; 11(4):267-2741 C1 [Berlanga, Mercedes] Univ Barcelona, Fac Pharm, Dept Microbiol & Parasitol, E-08028 Barcelona, Spain.

As PKC beta and PI3K/AKT signaling are both involved in breast cancer pathogenesis, this phase II study evaluated the efficacy and toxicity of enzastaurin in previously treated patients with metastatic breast cancer (MBC). Patients and Methods: Eligible patients had histologically confirmed MBC with measurable disease, and must have received prior anthracycline and taxane chemotherapy, but not more than two prior regimens for MBC. Human epidermal growth factor 2 (HER2)-positive patients must have progressed on prior trastuzumab therapy. Enzastaurin, 1,125-mg loading dose on day 1 followed by 500 mg daily, was administered orally in 28-day cycles. Response was assessed every 2 cycles according to the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Results: Twenty-one patients enrolled between November 2006 and September 2007. Fourteen (66.7%) patients completed at least two cycles of therapy. No patients developed Grade 3/4 hematologic toxicity. Grade 3 nonhematologic toxicity was rare (< 5%) and most commonly attributed to MBC progression. There were no objective responses and no patients with stable disease for a parts per thousand yen6 months. Median progression-free survival was 1.68 months (95%CI: 1.02, 1.74). Conclusions: Enzastaurin monotherapy was well tolerated, but demonstrated no activity in patients with heavily pretreated MBC.

BACKGROUND Cardiovascular interventions such as percutaneous aortic valve replacement require transfemoral delivery of large-bore intra-arterial catheters; therefore, pre-procedural assessment of aortoiliofemoral anatomy is important. CT angiography is ideal for this purpose but requires a large volume of intravenous contrast. METHODS Consecutive patients requiring evaluation of aortoiliofemoral anatomy underwent conventional anteroposterior projection iliac angiography during cardiac catheterization. A pigtail catheter was left in situ in the infrarenal abdominal aorta, and patients were transferred to the CT suite. Subsequently, 10 to 15 ml of contrast diluted with normal saline was injected intra-arterially via the pigtail catheter while a spiral CT of the abdomen and pelvis was acquired. Conventional angiographic and CT images were analyzed independently to assess suitability for large-bore (7-mm-diameter) intra-arterial catheter access. RESULTS Excellent CT image quality was achieved in 34 of 37 patients (92%). The mean contrast dose for CT was 12 +/- 2 ml. In 9 patients (24%), CT changed the assessment of femoral access feasibility. Furthermore, in another 7 patients (19%), unfavorable anatomy as shown by CT directed the avoidance of a particular side. Overall, CT findings altered the interventional approach in 16 patients (43%). There was no significant deterioration detected in renal function after coronary and CT angiography (estimated glomerular filtration rate 54.8 +/- 3.8 ml/min before 53.3 +/- 3.9 ml/min after, p = 0.55). CONCLUSIONS High-quality aortoiliofemoral CT angiography can be obtained with a technical success rate of >90% using 10 to 15 ml of contrast injected via a catheter in the abdominal aorta, and offers an alternative to conventional X-ray or CT angiography with high-volume intravenous contrast injection.

Background The ZES has different characteristics, with biocompatible polymer and rapid drug-elution, compared with the first-generation drug-eluting stents (DES). Methods The ENDEAVOR OCT (Evaluation in 3 Months Duration of Neointimal Coverage after Zotarolimus-Eluting Stent Implantation by Optical Coherence Tomography) trial is a prospective, single-center study evaluating vascular healing patterns with optical coherence tomography (OCT) at 3 months after stent implantation. A total of 31 ZES in 30 patients underwent serial OCT at immediate post-intervention and 3 months. Neointimal growth and malapposition were analyzed at each stent strut of cross-sectional OCT images with 0.5-mm intervals. Results The incidence of malapposition at post-intervention and 3 months was 6.0% and 0.2%, respectively. However, late acquired malapposition was not detected at 3 months. Of 31 stents, 27 stents (87.1%) were covered completely with neointima, but the remaining 4 stents had 2 (0.8%), 4 (0.9%), 4 (1.2%), and 6 (1.4%) uncovered struts. Overall mean percentage of covered stent struts was 99.9 +/- 0.4%. This finding was consistent among groups with acute coronary syndrome and stable angina pectoris (99.9 +/- 0.3% vs. 99.9 +/- 0.4%, p = 0.92). Intracoronary thrombus was documented in 1 stent (3.2%) among 31 stents. Conclusions Most of the stent struts were covered with neointima, and late acquired malapposition was not found at 3 months after ZES implantation.

TI Anatomy of the Distal Incus in Humans SO JARO-JOURNAL OF THE ASSOCIATION FOR RESEARCH IN OTOLARYNGOLOGY LA English DT Article DE incus; lenticular process; incus necrosis; middle-ear mechanics; incudo-stapedial joint AB The anatomy of the distal incus, including the lenticular process, was examined in histological sections from 270 normal cadaveric human temporal bones aged between less than 1 month and 100 years. All but nine of these sectioned specimens showed signs of a bony connection between the long process of the incus and the flattened plate of the lenticular process, and in 108 specimens a complete bony attachment was observed in a single 20 mu m section. In these 108 ears, the bony lenticular process consisted of a proximal narrow "pedicle" connected to a distal flattened "plate" that forms the incudal component of the incudo-stapedial joint. A fibrous joint capsule extended from the stapes head to the pedicle of the lenticular process on all sides, where it was considerably thickened. Three-dimensional reconstructions made from serial 20 mu m sections of four bones provided views from all directions that easily convey the anatomical features of this region. Morphometric measurements of the bony architecture of the distal incus in 103 temporal bones were made, including lengths and cross-sectional areas, estimates of the percentage of lacunae containing osteocytes, and the degree of bone resorption. These measurements, analyzed as a function of age, provided an anatomic description over a large age range that can serve as a normal baseline against which structural pathology can be compared. Although none of the bony dimensions showed significant age dependence, the estimated percentage of bony lacunae that contain osteocytes decreased significantly with age. The results have implications for the roles of specific components on the coupling of ossicular motion across the incudo-stapedial joint, and provide insights regarding bone resorption at the level of the distal incus, which occurs clinically in some patients with chronic otitis media or after stapedectomy.

One of the most common comorbid anxiety disorder is posttraumatic stress disorder (PTSD), a condition which may develop after exposure to traumatic events, Such as military combat. In comparison with the general population, rates of both SUDs and PTSD are elevated among veterans. Recent data show that soldiers returning from Iraq and Afghanistan demonstrate high rates of co-occurring SUDs, PTSD, and traumatic brain injury. Careful assessment of these conditions is critical and may be complicated by symptom overlap. More research targeting integrated interventions for these conditions is needed to establish optimal treatments.

Methods: Data from two large controlled longitudinal family studies of boys and girls with and without ADHD and their siblings were used. Subjects (n = 168) were followed prospectively and blindly over an average follow-up period of 7 years. Comparisons were made between youth with unipolar major depression who did and did not switch to full or subthreshold BP-I disorder at the follow-up assessment. Subjects were assessed at baseline and follow-up on multiple domains of functioning. Positive family history of parental psychiatric disorders was also compared between groups. Results: ADHD was associated with a significantly higher risk for switches from unipolar to bipolar disorder (28% versus 6%; z = 2.80, p = 0.005). In subjects with ADHD, switches from unipolar to bipolar disorder were predicted by baseline comorbid conduct disorder, school behavior problems, and a positive family history of parental mood disorder. Limitations: Psychosis was an exclusionary criterion in the original ascertainment of the studies of ADHD probands, so we were unable to test this as a predictor of switching to BPD. Conclusions: ADHD is a risk factor for switches from unipolar to bipolar disorder, and switches could be predicted by the presence of baseline conduct disorder, school behavior problems, and a positive family history of a mood disorder in a parent. These characteristics can aid clinicians in their treatment of youth with MDD. (C) 2009 Elsevier B.V. All rights reserved.

Method: Multivariate analysis of covariance was used to analyze differences between normal weight, overweight, and obese adults (n = 821) above the age of 60 years. Results: Obesity but not overweight was associated with lower levels of physical activity and physical function. Within BMI groups, individuals who were physically active were less likely to have abnormal physical function scores compared to those who were sedentary. Compared to men, obese women had lower physical function scores, placing them at higher risk for future disability. Aging was associated with lower levels of physical activity and physical function. Discussion: The study illustrates the importance of avoiding obesity and participating in regular physical activity to prevent or slow down the loss of functioning in older age.

T-cell activation requires Ca2+ influx through Ca2+-release activated Ca2+ (CRAC) channels encoded by the gene ORAI1. Objective: Investigation of the genetic causes and the clinical phenotype of immunodeficiency in patients with impaired Ca2+ influx and CRAC channel function. Methods: DNA sequence analysis for mutations in the genes ORAI1, ORAI2, ORAI3, and stromal interaction molecule (STIM) 1 and 2, as well as mRNA and protein expression analysis of ORAI1 in immunodeficient patients. Immunohistochemical analysis of ORAI1 tissue distribution in healthy human donors. Results: We identified mutations in ORAI1 in patients from 2 unrelated families. One patient is homozygous for a frameshift nonsense mutation in ORAI1 (ORAI1-A88SfsX25), and a second patient is compound heterozygous for 2 missense mutations in ORAI1 (ORAI1-A103E/L194P). All 3 mutations abolish ORAI1 expression and impair Ca2+ influx and CRAC channel function. The clinical syndrome associated with ORAI1 deficiency is characterized by immunodeficiency with a defect in the function but not in the development of lymphocytes, congenital myopathy, and anhydrotic ectodermal dysplasia with a defect in dental enamel calcification. In contrast with the limited clinical phenotype, we found ORAI1 protein expression in a wide variety of cell types and organs. Conclusion: Ca2+ influx through ORAI1 is crucial for lymphocyte function in vivo. Despite almost ubiquitous ORAI1 expression, the channel has a nonredundant role in only a few cell types judging from the limited clinical phenotype in ORAI1-deficient patients.

TI Anxiety and depressive disorders in offspring at high risk for anxiety: A meta-analysis SO JOURNAL OF ANXIETY DISORDERS LA English DT Article DE Anxiety disorders; Depression; Children; Adolescents; High risk ID MAJOR DEPRESSION; PANIC DISORDER; SOCIAL PHOBIA; CHILDREN; PARENTS; PSYCHOPATHOLOGY; INTERVENTION; AGORAPHOBIA; INTERVIEW; WOMEN AB This paper presents a meta-analysis of studies examining prevalence of psychopathology among offspring of anxiety-disordered parents, with the purpose of determining overall risk among these offspring for developing anxiety and depressive disorders. Pooled odds ratios for these disorders among high-risk offspring, compared to offspring of psychiatric and non-psychiatric controls, were calculated. Sixteen papers (including three follow-up studies) were identified, encompassing 1892 offspring (ages 4-25 years). Results revealed that: (1) offspring of parents with anxiety disorders have greater risk for anxiety and depressive disorders than offspring of non-psychiatric controls (ORs = 3.91 and 2.67, respectively) and greater risk for anxiety disorders than offspring of psychiatric controls (OR = 1.84); (2) offspring of anxious parents have significantly greater odds of having each type of anxiety disorder and MDD compared to offspring of non-psychiatric controls (ORs range from 1.96 to 8.69); and (3) offspring of parents with anxiety only, anxiety plus MDD, and MDD only have similar odds of having anxiety and depressive disorders but significantly higher odds than offspring of parents without disorder. Results suggest that parental anxiety disorders confer significant risk for anxiety and depression in offspring. Additional studies are needed to examine whether there are differences among specific parental anxiety disorders. (C) 2009 Elsevier Ltd. All rights reserved.

Presence of anxiety disorders was assessed every 6 months over 3 years via Structured clinical interviews. Among individuals who had a new episode of anxiety, we confirmed previous findings that history of anxiety, increased anxiety sensitivity (the fear of anxiety related sensations), and increased neuroticism were significant predictors. We also found trend level support for assertiveness as a predictor of anxiety onset. However, of these variables, only history of anxiety and anxiety sensitivity provided unique prediction. We did not find evidence for negative life events as a predictor of onset of anxiety either alone or in interaction with other variables in a diathesis-stress model. These findings from a prospective longitudinal study are discussed in relation to the potential role of such predictors in primary or relapse prevention efforts. (C) 2009 Elsevier Ltd.

Dynamic correction for parallel conductance, G(P), and gain factor, alpha, in invasive murine left ventricular volume measurements. J Appl Physiol 107: 1693-1703, 2009. First published August 20, 2009; doi:10.1152/japplphysiol.91322.2008.-The conductance catheter technique could be improved by determining instantaneous parallel conductance (G(P)), which is known to be time varying, and by including a time-varying calibration factor in Baan's equation [alpha(t)]. We have recently proposed solutions to the problems of both time-varying G(P) and time-varying alpha, which we term "admittance" and "Wei's equation," respectively. We validate both our solutions in mice, compared with the currently accepted methods of hypertonic saline (HS) to determine G(P) and Baan's equation calibrated with both stroke volume (SV) and cuvette. We performed simultaneous echocardiography in closed-chest mice (n = 8) as a reference for left ventricular (LV) volume and demonstrate that an off-center position for the miniaturized pressure-volume (PV) catheter in the LV generates end-systolic and diastolic volumes calculated by admittance with less error (P < 0.03) (-2.49 +/- 15.33 mu l error) compared with those same parameters calculated by SV calibrated conductance (35.89 +/- 73.22 mu l error) and by cuvette calibrated conductance (-7.53 +/- 16.23 mu l ES and -29.10 +/- 31.53 mu l ED error). To utilize the admittance approach, myocardial permittivity (epsilon(m)) and conductivity (sigma(m)) were calculated in additional mice (n = 7), and those results are used in this calculation. In aortic banded mice (n = 6), increased myocardial permittivity was measured (11,844 +/- 2,700 control, 21,267 +/- 8,005 banded, P < 0.05), demonstrating that muscle properties vary with disease state. Volume error calculated with respect to echo did not significantly change in aortic banded mice (6.74 +/- 13.06 mu l, P = not significant). Increased inotropy in response to intravenous dobutamine was detected with greater sensitivity with the admittance technique compared with traditional conductance [4.9 +/- 1.4 to 12.5 +/- 6.6 mmHg/mu l Wei's equation (P < 0.05), 3.3 +/- 1.2 to 8.8 +/- 5.1 mmHg/mu l using Baan's equation (P = not significant)]. New theory and method for instantaneous G(P) removal, as well as application of Wei's equation, are presented and validated in vivo in mice. We conclude that, for closed-chest mice, admittance (dynamic G(P)) and Wei's equation (dynamic alpha) provide more accurate volumes than traditional conductance, are more sensitive to inotropic changes, eliminate the need for hypertonic saline, and can be accurately extended to aortic banded mice.

Novel treatments involving the injection of polymeric materials into the myocardium of the failing left ventricle (LV) are currently being developed, which may reduce elevated myofiber stresses during the cardiac cycle and act to retard the progression of heart failure. A finite element (FE) simulation-based method was developed in this study that can automatically optimize the injection pattern of the polymeric "inclusions" according to a specific objective function, using commercially available software tools The FE prerocessor TRUEGRID (R) was use to create a parametric axisymmetric LV mesh matched to experimentally measured end-diastole and end-systole metrics from dogs with coronary microembolization-induced heart failure. Passive and active myocardial material properties were defined by a pseudo-elastic-strain energy function and a time-varying elastance model of active contraction, respectively, that were implemented in the FE software L5-DYNA. The companion optimization software Ls-OPT was used to communicate directly with TRUEGRID (R) to determine FE model parameters, such as defining the injection pattern and inclusion characteristics. The optimization resulted in an intuitive optimal injection pattern (i.e., the one with the greatest number of inclusions) when the objective function was weighted to minimize mean end-diastolic and end-systolic myofiber stress and ignore LV stroke volume. In contrast, the optimization resulted in a nonintuitive optimal pattern (i.e., 3 inclusions longitudinally x 6 inclusions circumferentially) when both myofiber stress and stroke volume were incorporated into the objective function with different weights.

We used this model to assess femoral head deformation and repair in vivo by sequential magnetic resonance imaging and by correlating end-stage findings with histologic assessments. Methods: Ischemic necrosis of the femoral head was induced in ten three-week-old piglets by tying a silk ligature around the base of the femoral neck (intracapsular) and cutting the ligamentum teres. We used magnetic resonance imaging with the piglets under general anesthesia to study the hips at forty-eight hours and at one, two, four, and eight weeks. Measurements on magnetic resonance images in the midcoronal plane of the involved and control sides at each time documented the femoral head height, femoral head width, superior surface cartilage height, and femoral neck-shaft angle. Histologic assessments were done at the time of killing. Results: Complete ischemia of the femoral head was identified in all involved femora by magnetic resonance imaging at forty-eight hours. Revascularization began at the periphery of the femoral head as early as one week and was underway in all by two weeks. At eight weeks, magnetic resonance imaging and histologic analysis showed deformation of the femoral head and variable tissue deposition. Tissue responses included (1) vascularized fibroblastic ingrowth with tissue resorption and cartilage, intramembranous bone, and mixed fibro-osseous or fibro-cartilaginous tissue synthesis and (2) resumption of endochondral bone growth. At eight weeks, the mean femoral head measurements (and standard error of the mean) for the control compared with the ligated femora were 10.4 +/- 0.4 and 4.8 +/- 0.4 mm, respectively, for height; 26.7 +/- 0.8 and 31.2 +/- 0.8 mm for diameter; 1.1 +/- 0.1 and 2.3 +/- 0.1 mm for cartilage thickness; and 151 degrees +/- 2 degrees and 135 degrees +/- 2 degrees for the femoral neck-shaft angle. Repeated-measures mixed-model analysis of variance revealed highly significant effects of ligation in each parameter (p < 0.0001). Conclusions: Magnetic resonance imaging allows for the assessment of individual hips at sequential time periods to follow deformation and repair. There was a variable tissue response, and histologic assessment at the time of killing was shown to correlate with the evolving and varying magnetic resonance imaging signal intensities. Femoral head height on the ischemic side from one week onward was always less than the initial control value and continually decreased with time, indicating collapse as well as slowed growth. Increased femoral head width occurred relatively late (four to eight weeks), indicating cartilage model overgrowth concentrated at the periphery.

TI The Relationship Between Electrogram Cycle Length and Dominant Frequency in Patients with Persistent Atrial Fibrillation SO JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY LA English DT Article DE atrial fibrillation; electrogram; spectral analysis; complex fractionated electrogram; ablation ID PULMONARY VEIN ISOLATION; CATHETER ABLATION; RADIOFREQUENCY ABLATION; RANDOMIZED-TRIAL; FRACTIONATION; SUBSTRATE; TERMINATION; ACTIVATION; MECHANISM; HUMANS AB Introduction: Sites of complex fractionated atrial electrograms (CFAE) with a short mean cycle length (MCL) and sites with a high dominant frequency (DF) have been advocated as targets for ablation in patients with persistent atrial fibrillation (AF). However, there are little data on the relationship between theses 2 markers. This study assessed the relationship between the DF and electrogram MCL after pulmonary vein (PV) isolation in patients with persistent AF. Methods and Results: A total of 44 patients with persistent AF were studied. Four-second bipolar electrograms were obtained with a multielectrode mapping catheter at regions throughout the left atrium after isolation of the pulmonary veins, with analysis of the MCL and DF at each site. The DF was defined as the largest frequency peak within a 2.5- to 16-Hz spectral profile generated with fast Fourier transformation of the electrogram. A total of 9,262 electrograms from the 44 patients were analyzed. The average MCL and DF post-PV isolation were 135 +/- 24 ms and 6.1 +/- 0.6 Hz, respectively. There was a statistically significant but weak correlation between the MCL and DF (r = 0.21, P < 0.001). Additionally, analysis of this relationship within each patient did not demonstrate a strong correlation (range of r values per patient = -0.18 to 0.47). Conclusions: There is a poor correlation between the electrogram MCL and DF in patients with persistent AF. Ablation strategies targeting DF and those targeting CFAE are therefore unlikely to direct ablation toward similar left atrial sites. Comparative studies are necessary to determine the effectiveness of each strategy in guiding catheter ablation of persistent AF. (J Cardiovasc Electrophysiol, Vol. 20, pp. 1336-1342, December 2009).

This review summarizes recent advancements in the characterization of the binding of SPARC to collagens and describes the results of studies that implicate a function for SPARC in the regulation of the assembly of basal lamina and fibrillar collagen in the ECM.

Barzu et al. (1994) suggested that the antiproliferative effect of HP on rat aortic smooth muscle cell in vitro diminishes with prolonged exposure to heparin. We exposed cultured bovine PASMC (BPASMC) to prolonged pretreatment with 20 mu g/ml of 0-hexanoylated HP from passages 3 to 13 and compared them to control (no pretreatment) cultures of identical passages. The pretreated BPASMC and control groups were growth arrested for 48 h, followed by treatment of 0-hexanoylated HP at different doses. On day 5, the growth inhibition of BPASMC was determined. The percent inhibition by 1 mu g/ml of 0-hexanoylated HP was 46 +/- 14% versus 62 +/- 13%, for control and pretreated BPASMC, respectively. At 10 mu g/ml the inhibition was 62 +/- 7% versus 84 +/- 6%. For 100 mu g/ml the inhibition increased to 92 +/- 5% versus 100% and at 200 mu g/ml the inhibition was 95 +/- 3% versus 100%. BPASMC (with or without preexposure to 0-hexanoylated HP), at passage 13, were sensitive to the growth inhibitory effect of 0-hexanoylated HP with no significant difference among the groups (95 +/- 3% inhibition vs. 100% for pretreated BPASMC). We found that 0-hexanoylated HP-induced necrosis as shown by flow cytometry and only minor apoptosis. Caspase-3 and PARP detection was insignificant between the groups. In summary, no cell subpopulation at long-term treatment exhibited resistance to 0-hexanoylated HP. The HP antiproliferative effect on SMC is potentially important in defining new approaches to the treatment of the remodeled vasculature of pulmonary hypertension. J. Cell.

Women with AN and HA have elevated cortisol levels. Significant hypercortisolemia, as in Cushing's disease, causes bone loss. It is unknown whether anxiety and depression and/or cortisol dysregulation contribute to low bone density in AN or HA. Objective: Our objective was to investigate whether hypercortisolemia is associated with bone loss and mood disturbance in women with HA and AN. Design and Setting: We conducted a cross-sectional study in a clinical research center. Participants: We studied 52 women [21 healthy controls (HC), 13 normal-weight women with functional HA, and 18 amenorrheic women with AN]. Outcome Measures: Serum samples were measured every 20 min for 12 h overnight and pooled for average cortisol levels. Bone mineral density (BMD) was assessed by dual-energy x-ray absorptiometry (DXA) at anteroposterior and lateral spine and hip. Hamilton Rating Scales for Anxiety (HAM-A) and Depression (HAM-D) were administered. Results: BMD was lower in AN and HA than HC at all sites and lower in AN than HA at the spine. On the HAM-D and HAM-A, AN scored higher than HA, and HA scored higher than HC. Cortisol levels were highest in AN, intermediate in HA, and lowest in HC. HAM-A and HAM-D scores were associated with decreased BMD. Cortisol levels were positively associated with HAM-A and HAM-D scores and negatively associated with BMD. Conclusions: Hypercortisolemia is a potential mediator of bone loss and mood disturbance in these disorders.

TI Effects of Aromatase Inhibition on Bone Mineral Density and Bone Turnover in Older Men with Low Testosterone Levels SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID RANDOMIZED CONTROLLED-TRIAL; ESTROGEN PLUS PROGESTIN; LOW SERUM TESTOSTERONE; ELDERLY-MEN; ANDROGEN DEFICIENCY; HYPOGONADAL MEN; SEX STEROIDS; POSTMENOPAUSAL WOMEN; PARATHYROID-HORMONE; PROSTATE-CANCER AB Context: Aging is associated with declining gonadal steroid production, low bone mineral density (BMD), and fragility fractures. The efficacy and safety of testosterone replacement in older men remains uncertain. Objective: The objective of the study was to assess the effects of aromatase inhibition on BMD in older men with low testosterone levels. Design and Setting: This was a 1-yr, double-blind, randomized, placebo-controlled trial that was conducted at a tertiary care academic center in Boston, MA. Participants: Participants included 69 men aged 60+ yr with borderline or low testosterone levels and hypogonadal symptoms. Intervention: Intervention included 1 mg anastrozole daily or placebo. Main Outcome Measures: Changes in gonadal steroid hormone levels, BMD, and bone turnover markers were measured. Results: Mean serum testosterone increased from 319 +/- 93 ng/dl at baseline to 524 +/- 139 ng/dl at month 3 (P < 0.0001) and declined slightly to 474 +/- 145 ng/dl by 1 yr. Estradiol levels decreased from 15 +/- 4 pg/ml at baseline to 12 +/- 4 pg/ml at month 3 and then remained stable (P < 0.0001). Posterior-anterior (PA) spine BMD decreased in the anastrozole group as compared with placebo (P = 0.0014). In the anastrozole group, PA spine BMD decreased from 1.121 +/- 0.141 g/cm(2) to 1.102 +/- 0.138 g/cm(2), whereas in the placebo group, PA spine BMD increased from 1.180 +/- 0.145 g/cm(2) to 1.189 +/- 0.146 g/cm(2). Qualitatively similar, but not statistically significant, changes occurred at the other sites. Bone turnover markers were not affected by anastrozole therapy. Conclusions: In older men, aromatase inhibition increases testosterone levels, decreases estradiol levels, and appears to decrease BMD. Aromatase inhibition does not improve skeletal health in aging men with low or low normal testosterone levels.

TI Concomitant Medication Use Can Confound Interpretation of the Combined Dexamethasone-Corticotropin Releasing Hormone Test in Cushing's Syndrome SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID STIMULATION TEST; DIAGNOSIS; HYPERCORTISOLISM; DISEASE; STATES AB Context: The ability of combined dexamethasone-corticotropin releasing hormone (Dex-CRH) testing to distinguish pseudo-Cushing's syndrome (PCS) from Cushing's syndrome is controversial. One factor potentially impairing diagnostic efficacy is the concomitant use of commonly prescribed medications that may alter dexamethasone metabolism. Objective: Our objective was to assess the diagnostic accuracy of the Dex-CRH test and evaluate the potential impact of concomitant drugs. Design: The study was a retrospective one. Participants: Participants included 101 patients [60 Cushing's disease (CD); 41 PCS] who underwent 112 Dex-CRH tests. Patients were divided into two groups, depending on use of medications potentially interfering with dexamethasone metabolism: 58 tests were classified as No Meds (32 CD; 26 PCS) and 54 as Meds (34 CD; 20 PCS). The latter group was further subdivided into patients taking one medication vs. those taking multiple medications. Main Outcome Measures: Diagnostic accuracy of different serum cortisol and ACTH thresholds at baseline and 15 min after CRH injection was assessed. Results: The specificity of a baseline post-low-dose-dexamethasone-suppressed test cortisol lower than 1.4 mu g/dl (38 nmol/liter) was significantly higher in the No Meds vs. the Meds group (P = 0.014). Sensitivity and specificity using a post-CRH cortisol cutoff of 1.4 mu g/dl (38 nmol/liter) were 93.1% (95% confidence interval = 88.4-97.8) and 92.3% (95% confidence interval = 87-97.6) in the No Meds group. The specificity of a cortisol lower than 1.4 mu g/dl (38 nmol/l) at 15 min after CRH was significantly higher in patients taking only one medication vs. those on multidrug treatment (P < 0.05). Conclusions: Medications commonly prescribed in hypercortisolemic patients undergoing Dex-CRH testing may contribute to the variable diagnostic accuracy of this test. Prospective studies to address this issue are needed. (J Clin Endocrinol Metab 94: 4851-4859, 2009) C1 [Biller, Beverly M.

Objective: The aim of the study was to determine the impact of BMI on peak GH to provocative testing in children with short stature. Design, Setting, and Participants: This was a retrospective review of provocative GH testing performed in 116 children 2-18 yr old in the ambulatory clinic of the Pediatric Endocrinology Unit at the Massachusetts General Hospital from 2004-2008. Main Outcome Measures: The main outcome measure was peak stimulated GH. Height, weight, IGF-I, and IGF-binding protein 3 were also measured. Results: In univariate regression analysis, BMI SD score (BMI SDS) was inversely associated with natural log (ln) peak GH to provocative testing (P = 0.002), whereas height SDS, ln IGF-I, and IGF-binding protein 3 were not significantly associated with ln peak GH. After controlling for age, gender, BMI, and pubertal status, BMI (P = 0.002) remained independently associated with ln peak GH. BMI SDS significantly influenced the likelihood of diagnosis of GH deficiency using peak GH cutoffs of 10, 7, and 5 mu g/liter. Conclusion: In children with short stature, BMI affects peak stimulated GH and should be considered when interpreting GH testing. Higher BMI SDS, even within the normal range, may lead to overdiagnosis of GH deficiency.

TI Mitochondrial Function and Insulin Resistance in Overweight and Normal-Weight Children SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID TYPE-2 DIABETIC-PATIENTS; OXIDATIVE-PHOSPHORYLATION; GLUCOSE-METABOLISM; AMERICAN CHILDREN; SKELETAL-MUSCLE; PUBERTY; ADOLESCENTS; OBESITY; SENSITIVITY; GENES AB Background: Obesity has become an epidemic in children, associated with an increase in insulin resistance and metabolic dysfunction. Mitochondrial function is known to be an important determinant of glucose metabolism in adults. However, little is known about the relationship between mitochondrial function and obesity, insulin resistance, energy expenditure, and pubertal development in children. Methods: Seventy-four participants, 37 overweight (>= 85th percentile body mass index for age and sex) and 37 normal-weight (<85th percentile) without personal or family history of diabetes mellitus were enrolled. Subjects were evaluated with an oral glucose tolerance test, metabolic markers, resting energy expenditure, Tanner staging, and (31)P magnetic resonance spectroscopy of skeletal muscle for mitochondrial function. Results: Overweight and normal-weight children showed no difference in muscle ATP synthesis [ phosphocreatine (PCr) recovery after exercise] (32.4 +/- 2.3 vs. 34.1 +/- 2.1, P = 0.58). However, insulin-resistant children had significantly prolonged PCr recovery when compared with insulin sensitive children, by homeostasis model assessment for insulin resistance quartile (ANOVA, P = 0.04). Similarly, insulin-resistant overweight children had PCr recovery that was prolonged compared with insulin-sensitive overweight children (P = 0.01). PCr recovery was negatively correlated with resting energy expenditure in multivariate modeling (P = 0.03). Mitochondrial function worsened during mid-puberty in association with insulin resistance. Conclusion: Reduced skeletal muscle mitochondrial oxidative phosphorylation, assessed by PCr recovery, is associated with insulin resistance and an altered metabolic phenotype in children. Normal mitochondrial function may be associated with a healthier metabolic phenotype in overweight children. Further studies are needed to investigate the long-term physiological consequences and potential treatment strategies targeting children with reduced mitochondrial function.

TI Criteria for Polycystic Ovarian Morphology in Polycystic Ovary Syndrome as a Function of Age SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID ANTRAL FOLLICLE COUNTS; IMPAIRED GLUCOSE-TOLERANCE; REGULAR MENSTRUAL CYCLES; NORMAL WOMEN; MENOPAUSAL TRANSITION; POSTMENOPAUSAL WOMEN; PROVEN FERTILITY; INFERTILE WOMEN; NATURAL-HISTORY; YOUNG-WOMEN AB Concept: Ovaries meeting criteria for polycystic ovary morphology during peak reproductive years may no longer meet the criteria with age. Objective: Ovarian volume and follicle number decrease with age in women with polycystic ovary syndrome (PCOS), permitting age-dependent criteria for PCOM. Design and Setting: We conducted longitudinal (7-15 year interval) and cross-sectional studies to examine polycystic ovarian morphology over time at an outpatient clinic and pathology laboratory in a tertiary care hospital. Patients: Subjects included those with PCOS defined by the National Institutes of Health criteria (n = 11 and 483 for longitudinal and cross-sectional, respectively) and control women with regular menstrual cycles and no hyperandrogenism (n = 15 and 367), age 18-64 yr. Interventions: Subjects underwent an ovarian ultrasound by a single observer. Main Outcome Measures: Ovarian volume and follicle number were measured and ultrasound findings confirmed by a pathologist in a subset (n = 9). Results: Ovarian volume (15.2 +/- 7.4 vs. 7.1 +/- 3.7 ml; P < 0.01) and follicle number (12.8 +/- 3.2 vs. 8.1 +/- 3.9; P < 0.05) decreased longitudinally in PCOS and control women(volume 11.6 +/- 4.4 vs. 5.4 +/- 2.2 ml and follicle number 8.3 +/- 1.9 vs. 6.3 +/- 1.8; both P < 0.005). Using cross-sectional data, log ovarian volume and follicle number decreased in both groups, but the decrease in log ovarian volume was less pronounced in women with PCOS than in controls (P < 0.01). A combination of age, log ovarian volume, follicle number, and testosterone distinguished PCOS subjects from controls with a receiver operator characteristic curve area of 0.90. Conclusions: Ovarian volume and follicle number decrease with age in women with PCOS and controls necessitating age-based criteria to define polycystic ovarian morphology. It is possible to use these criteria to distinguish PCOS in women over age 40 yr. (J Clin Endocrinol Metab 94: 4961-4970, 2009) C1 [Alsamarai, S.; Adams, J. M.; Murphy, M. K.; Hall, J. E.; Welt, C.

TI Reduced Growth Hormone Secretion Is Associated with Increased Carotid Intima-Media Thickness in Obesity SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID CARDIOVASCULAR RISK MARKERS; ADULT GH DEFICIENCY; C-REACTIVE PROTEIN; BODY-MASS INDEX; POLYCYSTIC-OVARY-SYNDROME; HYPOPITUITARY ADULTS; PLASMINOGEN-ACTIVATOR; WOMEN; ARGININE; INSULIN AB Context: Obesity is associated with reduced GH. Objective: The aim of the study was to determine whether reduced GH is associated with increased carotid intima-media thickness (cIMT) in obesity. Design: A total of 102 normal-weight and obese men and women without known hypopituitarism were studied. Subjects underwent GH stimulation testing with GHRH-arginine. Lipid profile, inflammatory markers, oral glucose tolerance test, abdominal computed tomography, dual-energy x-ray absorptiometry, and cIMT were measured. Relative GH deficiency was defined as peak GH of 4.2 mu g/liter or less. Subjects were separated based on BMI and GH testing into three groups: normal weight, obese GH sufficient (GHS), and obese relative GH deficient (GHD). Age, gender, and race were similar between the groups. BMI, percentage body fat, and visceral adiposity did not differ between obese GHS and relative GHD. Results: Peak GH was associated with cIMT, IGF-I, high-density lipoprotein, low-density lipoprotein, triglycerides, adiponectin, C-reactive protein, and TNF-alpha (all P < 0.05). Obese GHS subjects had similar cIMT compared to normal-weight subjects (P = not significant), whereas obese GHD subjects had higher cIMT compared to normal-weight subjects (P < 0.05) (normal weight, 0.645 +/- 0.023, vs. obese GHS, 0.719 +/- 0.021, vs. obese GHD, 0.795 +/- 0.063 mm; P = 0.01 by ANOVA). Similar results were seen in sensitivity analyses with less stringent cutoffs (<5, <= 8, <9 mu g/liter) to define GHD. In multivariate modeling, peak GH remained significantly associated with cIMT after controlling for age, gender, race, tobacco, blood pressure, cholesterol, and fasting glucose (R(2) for model, 0.35; P < 0.0001). Conclusions: These results suggest that reduced GH secretion is associated with a more abnormal metabolic phenotype in obesity, characterized by increased cIMT, dyslipidemia, insulin resistance, and inflammation.

Although the topic of patient adherence to health care practitioner recommendations is less than desirable and medication noncompliance adds to the cost of health care, another issue that affects the ability to attain optimal BP control is therapeutic, or clinical, inertia, which is the failure of health care providers to initiate or intensify therapy when indicated. This paper will discuss therapeutic inertia and other issues that prevent BP goal attainment.J Clin Hypertens (Greenwich). 2009;11:S5-S12. (C) 2009 Wiley Periodicals, Inc.

TI Multicenter, Phase I, Dose-Escalation Trial of Lenalidomide Plus Bortezomib for Relapsed and Relapsed/Refractory Multiple Myeloma SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID OVERCOMES DRUG-RESISTANCE; REFRACTORY MYELOMA; DEXAMETHASONE; THERAPY; THALIDOMIDE; CELLS; COMBINATION; PREDNISONE; MELPHALAN; ANALOGS AB Purpose Lenalidomide and bortezomib are active in relapsed and relapsed/refractory multiple myeloma (MM). In preclinical studies, lenalidomide sensitized MM cells to bortezomib and dexamethasone. This phase I, dose-escalation study (ie, NCT00153933) evaluated safety and determined the maximum-tolerated dose (MTD) of lenalidomide plus bortezomib in patients with relapsed or with relapsed and refractory MM. Patients and Methods Patients received lenalidomide 5, 10, or 15 mg/d on days 1 through 14 and received bortezomib 1.0 or 1.3 mg/m(2) on days 1, 4, 8, and 11 of 21-day cycles. Dexamethasone (20mg or 40 mg on days 1, 2, 4, 5, 8, 9, 11, and 12) was added for progressive disease after two cycles. Primary end points were safety and MTD determination. Results Thirty-eight patients were enrolled across six dose cohorts. The MTD was lenalidomide 15 mg/d plus bortezomib 1.0 mg/m(2). Dose-limiting toxicities (n = 1 for each) were grade 3 hyponatremia and herpes zoster reactivation and grade 4 neutropenia. The most common treatment-related, grades 3 to 4 toxicities included reversible neutropenia, thrombocytopenia, anemia, and leukopenia. Among 36 response-evaluable patients, 61% (90% CI, 46% to 75%) achieved minimal response or better. Among 18 patients who had dexamethasone added, 83% (90% CI, 62% to 95%) achieved stable disease or better. Median overall survival was 37 months. Conclusion Lenalidomide plus bortezomib was well tolerated and showed promising activity with durable responses in patients with relapsed and relapsed/refractory MM, including patients previously treated with lenalidomide, bortezomib, and/or thalidomide. The combination of lenalidomide, bortezomib, and dexamethasone is being investigated in a phase II study in this setting and in newly diagnosed MM.

TI Prognostic Factors for Overall Survival in Patients With Metastatic Renal Cell Carcinoma Treated With Vascular Endothelial Growth Factor-Targeted Agents: Results From a Large, Multicenter Study SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID PHASE-III TRIAL; DOSE INTERLEUKIN-2; INTERFERON-ALPHA; SUNITINIB; THROMBOCYTOSIS; SORAFENIB; THERAPY; CANCER; MODEL AB Purpose There are no robust data on prognostic factors for overall survival ( OS) in patients with metastatic renal cell carcinoma (RCC) treated with vascular endothelial growth factor (VEGF)-targeted therapy. Methods Baseline characteristics and outcomes on 645 patients with anti-VEGF therapy-naive metastatic RCC were collected from three US and four Canadian cancer centers. Cox proportional hazards regression, followed by bootstrap validation, was used to identify independent prognostic factors for OS. Results The median OS for the whole cohort was 22 months (95% CI, 20.2 to 26.5 months), and the median follow-up was 24.5 months. Overall, 396, 200, and 49 patients were treated with sunitinib, sorafenib, and bevacizumab, respectively. Four of the five adverse prognostic factors according to the Memorial Sloan-Kettering Cancer Center (MSKCC) were independent predictors of short survival: hemoglobin less than the lower limit of normal (P < .0001), corrected calcium greater than the upper limit of normal (ULN; P = .0006), Karnofsky performance status less than 80% (P < .0001), and time from diagnosis to treatment of less than 1 year (P < .01). In addition, neutrophils greater than the ULN (P < .0001) and platelets greater than the ULN (P = .01) were independent adverse prognostic factors. Patients were segregated into three risk categories: the favorable-risk group ( no prognostic factors; n = 133), in which median OS (mOS) was not reached and 2-year OS (2y OS) was 75%; the intermediate-risk group ( one or two prognostic factors; n = 301), in which mOS was 27 months and 2y OS was 53%; and the poor-risk group ( three to six prognostic factors; n = 152), in which mOS was 8.8 months and 2y OS was 7% (log-rank P < .0001). The C-index was 0.73. Conclusion This model validates components of the MSKCC model with the addition of platelet and neutrophil counts and can be incorporated into patient care and into clinical trials that use VEGF-targeted agents.

Method: Fifty-seven adults with DSM-IV MDD were randomly assigned from January 2003 until June 2006 to receive 1 g/d of eicosapentaenoic acid (EPA) or placebo for 8 weeks in a double-blind, randomized, controlled pilot study. Response criteria were on the basis of the 17-item Hamilton Depression Rating Scale (HDRS-17). Subjects' plasma lipid profiles were examined by gas chromatography. Results: Thirty-five subjects (63% female; mean +/- SD age = 45 +/- 13 years) were eligible for the intent-to-treat (ITT) analysis. In the ITT sample, mean +/- SD HDRS-17 scores decreased from 21.6 +/- 2.7 to 13.9 +/- 8.9 for the EPA group (n = 16) and from 20.5 +/- 3.6 to 17.5 +/- 7.5 for the placebo group (n = 19) (P = .123); the effect size for EPA was 0.55. ITT response rates were 38% (6/16) for EPA, and 21% (4/19) for placebo (P = .45). Among the 24 study completers, mean +/- SD HDRS-17 scores decreased from 21.3 +/- 3.0 to 11.1 +/- 8.1 for the EPA group and from 20.5 +/- 3.8 to 16.3 +/- 6.9 for the placebo group (P = .087); the effect size for EPA was 0.73. Completer response rates were 45% (5/11) for EPA, and 23% (3/13) for placebo (P = .39). Among EPA subjects, baseline n-6/n-3 ratio was associated with decrease in HDRS-17 score (r = -0.686, P = .030) and with treatment response (P = .032); change in n-6/n-3 ratio was associated with change in HDRS-17 score (r = .784, P = .032). Side effects, reported in 2 EPA subjects and 5 placebo subjects, were exclusively gastrointestinal, mild, and not associated with discontinuation. Conclusions: EPA demonstrated an advantage over placebo that did not reach statistical significance, possibly due to the small sample and low completer rates, which were the major study limitations.

TI Modafinil for Clozapine-Treated Schizophrenia Patients: A Double-Blind, Placebo-Controlled Pilot Trial SO JOURNAL OF CLINICAL PSYCHIATRY LA English DT Article ID DAYTIME SLEEPINESS; NEGATIVE SYMPTOMS; DEFICIT SYNDROME; SCALE; PSYCHOSIS; RELIABILITY; MEDICATIONS; COGNITION; SEDATION; FATIGUE AB Background: Patients with schizophrenia often suffer from cognitive deficits and negative symptoms that are poorly responsive to antipsychotics including clozapine. Clozapine-induced sedation can worsen cognition and impair social and occupational functioning. Objectives: To evaluate the efficacy, tolerability, and safety of modafinil for negative symptoms, cognition, and wakefulness/fatigue in DSM-IV-diagnosed schizophrenia patients treated with clozapine. Method: A double-blind, placebo-controlled, flexible-dosed 8-week pilot trial was conducted between September 2003 and September 2007, adding modafinil up to 300 mg/d to stabilized schizophrenia outpatients receiving clozapine. Psychopathology, cognition, and wakefulness/fatigue were assessed with standard rating scales. Results: Thirty-five patients were randomly assigned to treatment with study drug and included in the analysis. Modafinil did not reduce negative symptoms or wakefulness/fatigue or improve cognition compared to placebo. Modafinil was well tolerated and did not worsen psychosis. Conclusions: Results of this pilot trial do not support routine use of modafinil to treat negative symptoms, cognitive deficits, or wakefulness/fatigue in patients on clozapine. However, given our limited power to detect a treatment effect and the clear possibility of a type II error, larger trials are needed to resolve or refute a potential therapeutic effect of uncertain magnitude.

TI Distressing Sexual Problems in United States Women Revisited: Prevalence After Accounting for Depression SO JOURNAL OF CLINICAL PSYCHIATRY LA English DT Article ID HELP-SEEKING BEHAVIOR; DESIRE DISORDER; REPRESENTATIVE SAMPLE; PERSONAL DISTRESS; DYSFUNCTION; ANTIDEPRESSANTS; RELIABILITY; VALIDITY; HEALTH AB Objective. With data from the population based Prevalence of Female Sexual Problems Associated with Distress and Determinants of Treatment Seeking (PRESIDE) study, which has previously estimated the prevalence of sexual problems and sexually related personal distress in United States women, the prevalence of sexual disorders of desire, arousal, and orgasm was re-estimated, taking concurrent depression into consideration. Method: Current depression was defined in 3 ways as (1) self-reported symptoms alone, (2) antidepressant medication use alone, or (3) symptoms and/or antidepressant use. The unadjusted population prevalence for each distressing Sexual problem in the 31,581 respondents was calculated first irrespective of concurrent depression and then in women without concurrent depression, thus determining the size of the population with both conditions present. Results: The unadjusted population-based prevalence of desire disorder was 10.0% and was reduced to 6.3% for those without concurrent depression, leading to an estimate of 3.7% for those with both conditions present. The same pattern was observed for arousal and orgasm disorders, although overall prevalence estimates were lower. Conclusions: Our findings indicate that about 40% of those with a sexual disorder of desire, arousal, or orgasm have concurrent depression, As this study was cross-sectional, causality versus comorbidity cannot be determined. However, our findings stress the importance of evaluating depression along with sexual problems in routine clinical practice and epidemiology research.

Methods: A retrospective analysis of medical service and prescription claims from the Thomson Reuters (Healthcare) MarketScan Commercial Database (which includes claims information on >12 million employees with employer-based insurance and their dependents in the United States) was conducted. Claims data for 28,53 1 patients with bipolar disorder were compared for 1 year with data for 85,593 age- and sex-matched control patients with no mental health disorders and no psychotropic medication use. Results: Patients with bipolar disorder had a significantly higher prevalence of metabolic comorbidities than the general population (37% vs 30%, P < 0.0001), and annual medical service treatment costs for metabolic conditions were twice that of the control cohort ($531 vs $233, P < 0.0001). The bipolar cohort had significantly higher overall medical service and prescription drug costs than those of the control cohort ($12,764 vs $3,140, P < 0.0001). Prescription medication cost's for metabolic conditions were higher as well, with bipolar cohort per-patient costs of $571 versus $301 for the control cohort (P < 0.0001). Conclusions: Patients with bipolar disorder have significantly more metabolic comorbidities and higher medical costs than age- and sex-matched controls. Studies that link claims data with medical records or primary data collection pertaining to metabolic conditions may overcome limitations in the diagnostic information and Outcome predictors. To reduce the medical and economic burden of bipolar disorder, strategies should be identified to prevent the development of metabolic comorbidities and improve medication adherence.

TI Morphology of Retinal Ganglion Cells in the Ferret (Mustela putorius furo) SO JOURNAL OF COMPARATIVE NEUROLOGY LA English DT Article DE carnivores; topography; dye filling; area centralis; visual streak; stratification; taxonomy ID LATERAL GENICULATE-NUCLEUS; STARBURST AMACRINE CELLS; CAT RETINA; RABBIT RETINA; RECEPTIVE-FIELDS; ALPHA-GANGLION; DENDRITIC STRATIFICATION; CENTRAL PROJECTIONS; MAMMALIAN RETINA; PIGMENTED FERRET AB The ferret is the premiere mammalian model of retinal and visual system development, but the spectrum and properties of its retinal ganglion cells are less well understood than in another member of the Carnivora, the domestic cat. Here, we have extensively surveyed the dendritic architecture of ferret ganglion cells and report that the classification scheme previously developed for cat ganglion cells can be applied with few modifications to the ferret retina. We confirm the presence of alpha and beta cells in ferret retina, which are very similar to those in cat retina. Both cell types exhibited an increase in dendritic field size with distance from the area centralis (eccentricity) and with distance from the visual streak. Both alpha and beta cell populations existed as two subtypes whose dendrites stratified mainly in sublamina a or b of the inner plexiform layer. Six additional morphological types of ganglion cells were identified: four monostratified cell types (delta, epsilon, zeta, and eta) and two bistratified types (theta and iota). These types closely resembled their counterparts in the cat in terms of form, relative field size, and stratification. Our data indicate that, among carnivore species, the retinal ganglion cells resemble one another closely and that the ferret is a useful model for studies of the ontogenetic differentiation of ganglion cell types.
