In addition to electrocardiography and biomarkers, formal risk stratification using risk scores has become an important part of the initial evaluation of patients with ACS. On the basis of the estimated risk of subsequent ischemic events, the optimal use and timing of cardiac catheterization and revascularization procedures can be determined. Additionally, antiplatelet and anticoagulant therapy can be instituted, with consideration given to both the ischemic and bleeding risks in an individual patient. A particular challenge in ACS management has been the rapid evolution of guidelines in response to new randomized clinical trial and registry data. Understanding and implementing the recommendations in these evidence-based guidelines are important parts of hospitalists' practice. Journal of Hospital Medicine 2010; 5: S15-S21.

We aimed to examine seven ECG-based LVH criteria against two CT indexation criteria for LVH: a CT-specific body surface area cutoff and the obesity-independent height(2.7) criteria. Methods In 333 patients (mean age 53 +/- 12 years, 61% men), 64-slice contrast-enhanced CT was performed and 12-lead surface ECG within 24 h. Left ventricular mass was measured at end-diastole. Using both CT indexation criteria, the cohort was subdivided into patients with LVH and without LVH. The seven ECG criteria for LVH were the Cornell voltage index, Cornell voltage duration product, Cornell/strain index, Sokolow-Lyon index, Romhilt-Estes scores at least 4 and at least 5, and Gubner-Ungerleider. Results The ECG parameters had high specificities (85-97%) and variable low sensitivities (4-43%) when compared to either CT criteria of LVH. The three Cornell-based methods performed the best (test-positive likelihood ratio: 4.5-6.7), followed by the Sokolow-Lyon and Romhilt-Estes scores (test-positive likelihood ratio: 2.3-4.0). With the exception of the Gubner-Ungerleider criterion, the other six ECG criteria were associated with at least one of the CT-based LVH (adjusted odds ratio 2.4-9.5) and had incremental predictive value beyond that of hypertension history. Conclusion Using cardiac CT as a gold standard for LVH assessment, ECG criteria for LVH have high specificities with the three Cornell-based criteria providing the best test performance for identifying patients with LVH.

TI The CD4 receptor is complexed in detergent lysates to a protein-tyrosine kinase (pp58) from human T lymphocytes (Reprinted from Proceedings of the National Academy of Sciences, vol 85, pg 5190-5194, 1988) SO JOURNAL OF IMMUNOLOGY LA English DT Reprint ID CELL ANTIGEN RECEPTOR; AVIAN-SARCOMA VIRUS; CROSS-LINKING; ANTI-L3T4 ANTIBODIES; ACCESSORY CELLS; GENE-PRODUCT; ACTIVATION; PHOSPHORYLATION; RETROVIRUS; IDENTIFICATION AB The CD4 (T4) antigen is a cell-surface glyco-protein that is expressed predominantly on the surface of helper T cells and has been implicated in the regulation of T-cell activation and in the associative recognition of class II antigens of the major histocompatibility complex. In addition, the CD4 antigen appears to serve as a receptor for the human immunodeficiency virus (HIV). An important question has been whether the CD4 receptor is linked to an intracellular mediator that could regulate the activation of the CD4(+) subset. In this paper, we provide preliminary evidence that the CD4 receptor is complexed in detergent lysates to a protein-tyrosine kinase (PTK) of 55-60 kDa, which is expressed specifically in T cells. The PTK is the human analogue of the murine pp56(LSTRA) (pp56(lck)) and has significant homology with c-src, c-yes, and other members of the src family. The identification of the PTK associated with CD4 receptor was made by use of an antiserum to a synthetic peptide that was deduced from the DNA sequence of PTK. Two-dimensional nonequilibrium pH gradient gel electrophoresis/NaDodSO(4)/PAGE revealed the kinase to focus as a heterogeneous collection of spots in the pH range of 4.0-5.0. Furthermore, in vitro phosphorylation revealed the phosphorylation of two additional polypeptides at 40 and 80 kDa, in addition to the autophosphorylation of the PTK at 55-60 kDa. The potential importance of the association between the CD4 receptor and the PTK of T cells is discussed in relation to T-cell activation and HIV infectivity.

In this review, we discuss this pathway and highlight several novel exceptions recently found with a model influenza vaccine, such as mannose-binding lectin opsonization of influenza and uptake by macrophages, and the capture of virus by dendritic cells residing in the medullary compartment of peripheral lymph nodes.

TI Distinctive CD3 Heterodimeric Ectodomain Topologies Maximize Antigen-Triggered Activation of alpha beta T Cell Receptors SO JOURNAL OF IMMUNOLOGY LA English DT Article ID CRYSTAL-STRUCTURE; ZETA-CHAIN; CD3-EPSILON-GAMMA HETERODIMER; STEPWISE EVOLUTION; THYMIC SELECTION; FG LOOP; COMPLEX; MICE; CD3-GAMMA; FRAGMENT AB The alpha beta TCR has recently been suggested to function as an anisotropic mechanosensor during immune surveillance, converting mechanical energy into a biochemical signal upon specific peptide/MHC ligation of the alpha beta clonotype. The heterodimeric CD3 epsilon gamma and CD3 epsilon delta subunits, each composed of two Ig-like ectodomains, form unique side-to-side hydrophobic interfaces involving their paired G-strands, rigid connectors to their respective transmembrane segments. Those dimers are laterally disposed relative to the alpha beta heterodimer within the TCR complex. In this paper, using structure-guided mutational analysis, we investigate the functional consequences of a striking asymmetry in CD3 gamma and CD3 delta G-strand geometries impacting ectodomain shape. The uniquely kinked conformation of the CD3 gamma G-strand is crucial for maximizing Ag-triggered TCR activation and surface TCR assembly/expression, offering a geometry to accommodate juxtaposition of CD3 gamma and TCR beta ectodomains and foster quaternary change that cannot be replaced by the isologous CD3 delta subunit's extracellular region. TCR beta and CD3 subunit protein sequence analyses among Gnathostomata species show that the C beta FG loop and CD3 gamma subunit coevolved, consistent with this notion. Furthermore, restoration of T cell activation and development in CD3 gamma(-/-) mouse T lineage cells by interspecies replacement can be rationalized from structural insights on the topology of chimeric mouse/human CD3 epsilon delta dimers. Most importantly, our findings imply that CD3 gamma and CD3 delta evolved from a common precursor gene to optimize peptide/MHC-triggered alpha beta TCR activation.

Prior studies have also suggested a role for p190RhoGAP in beta(2) integrin signaling in neutrophils. To directly test that possibility, we have generated a novel targeted mutation completely disrupting the p190RhoGAP-encoding gene in mice. p190RhoGAP deficiency led to perinatal lethality and defective neural development, precluding the analysis of neutrophil functions in adult p190RhoGAP(-/-) animals. This was overcome by transplantation of fetal liver cells from p190RhoGAP(-/-) fetuses into lethally irradiated wild-type recipients. Neutrophils from such p190RhoGAP(-/-) bone marrow chimeras developed normally and expressed normal levels of various cell surface receptors. Although p190RhoGAP(-/-) neutrophils showed moderate reduction of beta(2) integrin-mediated adherent activation, they showed mostly normal migration in beta(2) integrin-dependent in vitro and in vivo assays and normal beta(2) integrin-mediated killing of serum-opsonized Staphylococcus aureus and Escherichia coli. A neutrophil-and beta(2) integrin-dependent transgenic model of the effector phase of autoimmune arthritis also proceeded normally in p190RhoGAP(-/-) bone marrow chimeras. In contrast, all the above responses were completely blocked in CD18(-/-) neutrophils or CD18(-/-) bone marrow chimeras. These results suggest that p190RhoGAP likely does not play a major indispensable role in beta(2) integrin-mediated in vitro and in vivo neutrophil functions or the effector phase of experimental autoimmune arthritis.

Microbial translocation contributes to immune activation and disease progression during chronic human immunodeficiency virus type 1 (HIV-1) infection. However, its role in the African AIDS epidemic remains controversial. Here, we investigated the relationship between markers of monocyte activation, plasma lipopolysaccharide (LPS), and HIV-1 RNA in South Africans prioritized to receive combination antiretroviral therapy (cART). Methods. Ten HIV-1-negative African controls and 80 HIV-1-infected patients with CD4 T cell counts <200 cells/mu L were sampled prior to (n = 60) or during (n = 20) receipt of effective cART. Viral load was measured by Nuclisens; LPS by the Limulus amoebocyte lysate assay; monocyte and T cell subsets by flow cytometry; and soluble CD14, cytokines, and chemokines by enzyme-linked immunosorbent assay and customized Bio-Plex plates. Results. Three distinct sets of markers were identified. CCL2, CXCL10, and CD14(+)CD16(+) monocyte levels were positively correlated with HIV-1 viremia. This finding, together with cART-induced normalization of these markers, suggests that their upregulation was driven by HIV-1. Plasma interleukin-6 was associated with the presence of opportunistic coinfections. Soluble CD14 and tumor necrosis factor were linked to plasma LPS levels and, as observed for LPS, remained elevated in patients receiving effective cART. Conclusions. Microbial translocation is a major force driving chronic inflammation in HIV-infected Africans receiving cART. Prevention of monocyte activation may be especially effective at enhancing therapeutic outcomes.

TI Intimate Partner Aggression Perpetrated and Sustained by Male Afghanistan, Iraq, and Vietnam Veterans With and Without Posttraumatic Stress Disorder SO JOURNAL OF INTERPERSONAL VIOLENCE LA English DT Article DE posttraumatic stress disorder; intimate partner aggression; domestic violence; veterans ID COMBAT VETERANS; INTERGENERATIONAL TRANSMISSION; RISK-FACTORS; MILITARY VETERANS; ALCOHOL-PROBLEMS; PHYSICAL ABUSE; VIOLENCE; ANGER; HOSTILITY; WAR AB Veterans with posttraumatic stress disorder (PTSD) consistently evidence higher rates of intimate partner aggression perpetration than veterans without PTSD, but most studies have examined rates of aggression among Vietnam veterans several years after their deployment. The primary aim of this study was to examine partner aggression among male Afghanistan or Iraq veterans who served during Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) and compare this aggression to that reported by Vietnam veterans with PTSD. Three groups were recruited, OEF/OIF veterans with PTSD (n = 27), OEF/OIF veterans without PTSD (n = 31), and Vietnam veterans with PTSD (n = 28). Though only a few comparisons reached significance, odds ratios suggested that male OEF/OIF veterans with PTSD were approximately 1.9 to 3.1 times more likely to perpetrate aggression toward their female partners and 1.6 to 6 times more likely to report experiencing female perpetrated aggression than the other two groups. Significant correlations among reports of violence perpetrated and sustained suggested many men may have been in mutually violent relationships. Taken together, these results suggest that partner aggression among Iraq and Afghanistan veterans with PTSD may be an important treatment consideration and target for prevention.

TI PD-1 on Immature and PD-1 Ligands on Migratory Human Langerhans Cells Regulate Antigen-Presenting Cell Activity SO JOURNAL OF INVESTIGATIVE DERMATOLOGY LA English DT Article ID PROGRAMMED DEATH-1 PD-1; ACTIVATED T-CELLS; DENDRITIC CELLS; STEADY-STATE; CONTACT HYPERSENSITIVITY; SIGNAL-TRANSDUCTION; TYROSINE KINASE; EXPRESSION; RECEPTOR; TOLERANCE AB Langerhans cells (LCs) are known as "sentinels'' of the immune system that function as professional antigen-presenting cells (APCs) after migration to draining lymph node. LCs are proposed to have a role in tolerance and the resolution of cutaneous immune responses. The Programmed Death-1 (PD-1) receptor and its ligands, PD-L1 and PD-L2, are a co-inhibitory pathway that contributes to the negative regulation of T-lymphocyte activation and peripheral tolerance. Surprisingly, we found PD-1 to be expressed on immature LCs (iLCs) in situ. PD-1 engagement on iLCs reduced IL-6 and macrophage inflammatory protein (MIP)-1 alpha cytokine production in response to TLR2 signals but had no effect on LC maturation. PD-L1 and PD-L2 were expressed at very low levels on iLCs. Maturation of LCs upon migration from epidermis led to loss of PD-I expression and gain of high expression of PD-L1 and PD-L2 as well as co-stimulatory molecules. Blockade of PD-L1 and/or PD-L2 on migratory LCs (mLCs) and DDCs enhanced T-cell activation, as has been reported for other APCs. Thus the PD-1 pathway is active in iLCs and inhibits iLC activities, but expression of receptor and ligands reverses upon maturation and PD-L1 and PD-L2 on mLC function to inhibit T-cell responses.

Phagocytic activity was found enhanced by apolipoprotein (apo) A-I and apoA-II more than twice the maximum in J774 and mouse peritoneal macrophages. Therefore we investigated the molecular basis of this reaction in association with the function of ABCA7. Similar to ABCA1, ABCA7 was degraded, likely by calpain, and apoA-I and apoA-II stabilize ABCA7 against degradation. Cell surface biotinylation experiments demonstrated that endogenous ABCA7 predominantly resides on the cell surface and that the apolipoproteins increase the surface ABCA7. The increase of phagocytosis by apolipoproteins was retained in the J774 cells treated with ABCA1 siRNA and in the peritoneal macrophages from ABCA1-knockout mice, but it was abolished in the J774 cells treated with ABCA7 siRNA and in the peritoneal macrophages from ABCA7-knockout mice. Phagocytosis was decreased in the cells in the peritoneal cavity of the ABCA7-knockout mouse compared with the wild-type control. We thus concluded that extracellular helical apolipoproteins augment ABCA7-associated phagocytosis by stabilizing ABCA7. The results demonstrated direct enhancement of the host defense system by HDL components.-Tanaka, N., S. Abe-Dohmae, N. Iwamoto, M. L. Fitzgerald, and S. Yokoyama.

TI HDL3, but not HDL2, stimulates plasminogen activator inhibitor-1 release from adipocytes: the role of sphingosine-1-phosphate SO JOURNAL OF LIPID RESEARCH LA English DT Article DE plasminogen activator inhibitor-1; fibrinolysis; lipoprotein; high-density lipoprotein ID SPHINGOSINE 1-PHOSPHATE RECEPTORS; DENSITY-LIPOPROTEIN BINDING; CORONARY-ARTERY-DISEASE; VEIN ENDOTHELIAL-CELLS; NITRIC-OXIDE SYNTHASE; SCAVENGER RECEPTOR; BIOLOGICAL-ACTIVITIES; GENE-EXPRESSION; ADIPOSE-TISSUE; CLASS-B AB Sphingosine-1-phosphate (S1P) is a bioactive lysophospholipid that regulates numerous key cardiovascular functions. High-density lipoproteins (HDLs) are the major plasma lipoprotein carriers of S1P. Fibrinolysis is a physiological process that allows fibrin clot dissolution, and decreased fibrinolytic capacity may result from increased circulating levels of plasminogen activator inhibitor-1 (PAI-1). We examined the effect of S1P associated with HDL sub-fractions on PAI-1 secretion from 3T3 adipocytes. S1P concentration in HDL3 averaged twice that in HDL2. Incubation of adipocytes with increasing concentrations of S1P in HDL3, but not HDL2, or with S1P complexed to albumin stimulated PAI-I secretion in a concentration-dependent manner. Quantitative RT-PCR revealed that S1P(1-3) are expressed in 3T3 adipocytes, with S1P(2) expressed in the greatest amount. Treatment of adipocytes with the S1P(1) and S1P(3) antagonist VPC23019 did not block PAI-1 secretion. Inhibiting S1P(2) with JTE-013 or reducing the expression of the gene coding for S1P(2) using silencing RNA (siRNA) technology blocked PAI-1 secretion, suggesting that the S1P(2) receptor mediates PAI-1 secretion from adipocytes exposed to HDL3 or S1P. Treatment with the phospholipase C (PLC) inhibitor U73122, the protein kinase C (PKC) inhibitor RO-318425, or the Rho-associated protein kinase (ROCK) inhibitor Y27632 all significantly inhibited HDL3- and S1P-mediated PAI-1 release, suggesting that HDL3- and/or S1P-stimulated PAI-1 secretion from 3T3 cells is mediated by activation of multiple, downstream signaling pathways of S1P(2).-Lee, M-H., S.

Materials and Methods: In eight mice tumor models, FAIR and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) was performed. The reliability for measuring blood flow on FAIR was evaluated using the coefficient of variation of blood flow on psoas muscle. Three regions of interest (ROIs) were drawn in the peripheral, intermediate, and central portions within each tumor. The location of ROI was the same on FAIR and DCE-MR images. The correlation between the blood flow on FAIR and perfusion-related parameters on DCE-MRI was evaluated using the Pearson correlation coefficient. Results: The coefficient of variation for measuring blood flow was 9.8%. Blood flow on FAIR showed a strong correlation with Kep (r = 0.77), percent relative enhancement (r = 0.731, and percent enhancement ratio (r = 0.81). The mean values of blood flow (mL/100 g/min) (358 vs. 207), Kep (sec(-1)) (7.46 vs. 1.31), percent relative enhancement (179% vs. 134%), and percent enhancement ratio (42% vs. 26%) were greater in the peripheral portion than in the central portion (P < 0.01). Conclusion: As blood flow measurement on FAIR is reliable and closely related with that on DCE-MR, FAIR is feasible for measuring tumor blood flow.

TI Transcriptional changes associated with recovery from heart failure in the SHR SO JOURNAL OF MOLECULAR AND CELLULAR CARDIOLOGY LA English DT Article DE Heart failure; Hypertension; Cardiac hypertrophy; Gene expression profiling; Angiotensin converting enzyme inhibition; Phenylbutyrate ID SPONTANEOUSLY HYPERTENSIVE-RAT; TUMOR-NECROSIS-FACTOR; CONVERTING ENZYME-INHIBITION; MATRIX-METALLOPROTEINASE ACTIVITY; LEFT-VENTRICULAR HYPERTROPHY; CARDIAC GENE-EXPRESSION; MYOCARDIAL FIBROSIS; MICROARRAY ANALYSIS; FAILING MYOCARDIUM; ENERGY-METABOLISM AB To identify biological pathways associated with myocardial recovery from heart failure (HF), gene profiling and gene set enrichment analysis (GSEA) were examined in left ventricle of spontaneously hypertensive rats with HF (SHR-F) with no treatment, following treatment with the angiotensin converting enzyme inhibitor captopril, and treatment with captopril combined with the short chain fatty acid derivative phenylbutyrate. Failing hearts demonstrated depressed left ventricular ejection fraction, while ventricular volume and mass increased. Captopril treatment alone prevented further deterioration but did not improve myocardial function; relatively few transcripts were differentially expressed relative to untreated SHR-F. Gene sets identified by GSEA as downregulated with captopril treatment compared to SHR-F group included those related to hypoxia and reactive oxygen species, while upregulated gene sets included G protein signaling. Treatment with phenylbutyrate alone did not improve survival (no animals in this group survived the 30 day treatment period), while phenylbutyrate combined with captopril increased survival and significantly improved cardiac function in vivo and in vitro. Normalized microarray data identified 780 genes that demonstrated a combined treatment effect of which 258 genes were modified with HF. Fatty acid metabolism and ion transport were among the most significantly upregulated pathways in the combined treatment group compared to untreated SHR with HF, whereas those related to oxidative stress, growth, inflammation, protein degradation, and TGF-beta signaling were downregulated. These findings demonstrate improved myocardial function and regression of cardiac hypertrophy, and identify many HF related gene sets altered with phenylbutyrate and captopril treatment, but not captopril alone. These results characterize gene sets associated with recovery from HF, and suggest that phenylbutyrate may be a potentially effective adjunctive treatment, together with captopril, by synergistically modulating pathways that contribute to restoration of contractile function of the failing SHR heart.

TI Addition of H19 'Loss of Methylation Testing' for Beckwith-Wiedemann Syndrome (BWS) Increases the Diagnostic Yield SO JOURNAL OF MOLECULAR DIAGNOSTICS LA English DT Article ID ASSISTED REPRODUCTIVE TECHNOLOGIES; MONOZYGOTIC TWINS DISCORDANT; NEONATAL DIABETES-MELLITUS; POLYMERASE-CHAIN-REACTION; IN-VITRO FERTILIZATION; UNIPARENTAL DISOMY; DNA METHYLATION; WILMS-TUMOR; ISOLATED HEMIHYPERPLASIA; IMPRINTED GENES AB Beckwith-Wiedemann syndrome (BWS) is a clinical diagnosis; however, molecular confirmation via abnormal methylation of DMR2(LIT1) and/or DMR1(H19) has clinical utility due to epigenotype-tumor association. Despite the strong link between H19 hypermethylation and tumor risk, several diagnostic laboratories only test for hypomethylation of LIT1 We assessed the added diagnostic value of combined LIT1 and H19 testing in a large series of referred samples from 1298 patients, including 53 well-characterized patients from the St. Louis Children's Hospital BWS-Registry (validation samples) and 1245 consecutive nationwide referrals (practice samples). Methylation-sensitive enzymatic digestion with Southern hybridization assessed loss of normal imprinting. In the validation group, abnormal LIT1 hypomethylation was detected in 60% (32/52) of patients but LIT1/H19-combined testing was abnormal in 68% (36/53); sensitivity in the practice setting demonstrated 27% (342/1245) abnormal LIT1 and 32% (404/1245) abnormal LIT1/H19-combined. In addition, H19 methylation was abnormal in 7% of LIT1-normal patients. We observed absence of uniparental disomy (UPD) in 27% of combined LIT1/H19-abnormal samples, diagnostic of multilocus methylation abnormalities; in contrast to studies implicating that combined LIT1/H19 abnormalities are diagnostic of UPD. The overall low detection rate, even in validated patient samples and despite characterization of both loci and UPD status, emphasizes the importance of clinical diagnosis in BWS.

Although the majority of these tumors can be effectively treated with surgery and radiation therapy, an important subset of patients have inoperable tumors, or develop recurrent disease after surgery and radiotherapy, and require some form of medical therapy. There are increasing numbers of studies evaluating various medical therapies but the results remain disappointing. Chemotherapies and hormonal therapies have been generally ineffective, although somatostatin analogues may have therapeutic potential. There is also increasing interest in targeted molecular therapies. Agents inhibiting platelet derived growth factor receptors and epidermal growth factor receptors have shown little efficacy, but molecular agents inhibiting vascular endothelial growth factor receptors appear to have some promise. As with other tumors, advances in the medical therapies for meningiomas will require improved understanding of the molecular pathogenesis of these tumors, more predictive preclinical models, and efficient mechanisms for conducting clinical trials, given the small population of eligible patients.

We surveyed the relevant literature available on intracranial meningioma surgery and subsequent outcomes (38 papers), making note of which, if any, QOL/outcome instruments were utilized. None of the surgveyed papers included QOL assessment specific to tumor site. We subsequently developed questions that were relevant to the signs and symptoms that characterize each of 11 intracranial meningioma sites, and incorporated them into a modified combination of the Functional Assessment of Cancer Therapy-Brain (FACT-BR) and SF36 outcome instruments, thereby creating a new tumor site-specific outcome instrument, FACT-MNG. With outcomes analysis of surgical and radiosurgical treatments becoming more important, measures of the adequacy and success of treatment are needed. FACT-MNG represents a first effort to formalize such an instrument for meningioma patients. Questions specific to tumor site will allow surgeons to better assess specific quality of life issues not addressed in the past by more general questionnaires.

Few cases of orbital involvement have been reported. A 51-year-old man with a history of WM developed bilateral orbitopathy and optic neuropathy. Orbital biopsy, cerebrospinal fluid studies, and neuroimaging confirmed the diagnosis of BNS involving the orbital soft tissues, optic nerves, meninges, and cauda equina. The neuro-ophthalmic manifestations resolved after parenteral and intrathecal chemotherapy in addition to autologous stem cell transplantation. The rare neuro-ophthalmic manifestations of BNS may require a multifaceted approach to therapy.

Recent studies from our laboratory reveal that grape seed-derived polyphenolic extracts (GSPE) potently prevent tau fibrillization into neurotoxic aggregates and therapeutically promote the dissociation of preformed tau aggregates [J. Alzheimer's Dis. (2009) vol. 16, pp. 433]. Based on our extensive bioavailability, bioactivity and functional preclinical studies, combined with the safety of GSPE in laboratory animals and in humans, we initiated a series of studies exploring the role of GSPE (Meganatural-Az (R) GSPE) as a potential novel botanical drug for the treatment of certain forms of tauopathies including PSP, a neurodegenerative disorder involving the accumulation and deposition of misfolded tau proteins in the brain characterized, in part, by abnormal intracellular tau inclusions in specific anatomical areas involving astrocytes, oligodendrocytes and neurons [J. Neuropathol. Exp. Neurol. (2002) vol. 61, pp. 33]. In this mini-review article, we discuss the biochemical characterization of GSPE in our laboratory and its potential preventative and therapeutic role in model systems of abnormal tau processing pertinent to PSP and related tauopathies.

We examined striatal dopamine (DA) function in hyperactive transgenic (Tg) mice generated as a model of dystonia. Evoked extracellular DA concentration was monitored with carbon-fiber microelectrodes and fast-scan cyclic voltammetry in striatal slices from non-Tg mice, Tg mice with a positive motor phenotype, and phenotype-negative Tg litter-mates. Peak single-pulse evoked extracellular DA concentration was significantly lower in phenotype-positive mice than in non-Tg or phenotype-negative mice, but indistinguishable between non-Tg and phenotype-negative mice. Phenotype-positive mice also had higher functional D2 DA autoreceptor sensitivity than non-Tg mice, which would be consistent with lower extracellular DA concentration in vivo. Multiple-pulse (phasic) stimulation (five pulses, 10-100 Hz) revealed an enhanced frequency dependence of evoked DA release in phenotype-positive versus non-Tg or phenotype-negative mice, which was exacerbated when extracellular Ca(2+) concentration was lowered. Enhanced sensitivity to phasic stimulation in phenotype-positive mice was reminiscent of the pattern seen with antagonism of nicotinic acetylcholine receptors. Consistent with a role for altered cholinergic regulation, the difference in phasic responsiveness among groups was lost when nicotinic receptors were blocked by mecamylamine. Together, these data implicate compromised DA release regulation, possibly from cholinergic dysfunction, in the motor symptoms of this dystonia model.

TI Diffusion weighted imaging reversibility in the brainstem following successful recanalization of acute basilar artery occlusion SO JOURNAL OF NEUROINTERVENTIONAL SURGERY LA English DT Article ID INTRAARTERIAL THROMBOLYSIS; ISCHEMIC-INJURY; STROKE PATIENTS; REVERSAL AB Acute basilar artery occlusion (ABAO) is a devastating disease that can produce significant brainstem injury. Pretreatment diffusion weighted imaging (DWI) demonstrating extensive brainstem involvement has been shown to predict a poor outcome regardless of reperfusion. This case report describes a patient presenting with coma secondary to ABAO. MRI at presentation demonstrated significant DWI abnormality in the majority of the bilateral pons. The basilar artery was endovascularly recanalized 8 h after stroke onset, and the patient had a marked clinical recovery with no deficit at 3 months. Follow-up imaging revealed significant reversal of the pontine lesion. This finding of brainstem DWI reversibility cautions against the use of DWI to select ABAO patients for intra-arterial stroke therapy. The degree of apparent diffusion coefficient reduction on pretreatment MRI may not adequately identify which DWI abnormal brainstem tissue is potentially reversible.

TI Palliation of compression fractures in cancer patients by vertebral augmentation: a retrospective analysis SO JOURNAL OF NEUROINTERVENTIONAL SURGERY LA English DT Article ID TREATMENT OPTIONS; RANDOMIZED-TRIAL; SINGLE-CENTER; VERTEBROPLASTY; KYPHOPLASTY; MANAGEMENT; EFFICACY; FUTURE AB Aim To evaluate the efficacy of vertebral augmentation (VA) in cancer patients. Materials and methods From a retrospectively compiled database, 147 cancer cases (236 levels) were treated with VA. Mean age was 71+/-12 years and 56.5% were female. Variables evaluated include age, sex, procedure type, vertebral level treated, number of levels treated per procedure and technical approach. Outcomes were assessed by a previously described method retrospectively applied from medical records: a binary system of 'responders' versus 'non-responders' and further subcategorization with a four level pain scale. Two patient groups were analyzed: (1) 147 cancer patients with either osteoporotic or malignant vertebral compression fractures (all compression fractures (ACFs)) and (2) 102 cases with documented metastatic compression fractures (MCFs). Univariate and multivariate analyses determined outcomes. Results 93% of MCFs and 88.5% of ACFs showed response to treatment (pain improvement or resolution): 30% of ACFs and 31% of MCFs experienced pain resolution. MCFs showed increasing age to be a predictor of response to treatment in univariate (OR = 1.79, p = 0.04) and multivariate (OR = 2.05, p = 0.03) analysis. In ACFs, bipedicular needle approach decreased the odds of pain resolution (OR = 0.28, p = 0.01). In MCFs, lung cancer (OR = 0.06, p = 0.03) and multiple myeloma (OR = 0.10, p = 0.01) decreased the odds of pain resolution. Conclusions VA provides pain relief for a majority of ACFs and MCFs. Increasing age may be predictive of pain relief outcomes in MCFs. There are special planning, imaging and technical considerations (eg, needle placement) in using VA to treat cancer patients.

A much less common phenomenon is the onset of stuttering in adults who sustain a stroke, traumatic brain injury, or other neurologic events. When stuttering occurs in association with neuropathology, precise characterization and explanation of observed behaviors is often difficult. Among the clinical challenges presented by acquired stuttering are the problem of distinguishing this form of dysfluency from those associated with dysarthria and aphasia, and identifying the neuropathological condition(s) and brain lesion site(s) giving rise to this speech disorder. Another challenge to the precise characterization of acquired stuttering is the fact that some cases of acquired stuttering apparently have a psychological or neuropsychiatric genesis rather than a neuropathological one. In this paper we provide a review of the literature pertaining to the complicated phenomenon of acquired stuttering in adults and draw some tentative explanatory conclusions regarding this disorder.

To address the hypothesis that abnormal corticostriatal connectivity arises from polyglutamine-related alterations in cortical gene expression, we isolated layer 5 cortical neurons by laser-capture microdissection and analyzed transcriptome-wide mRNA changes in them. Enrichment of transcription factor mRNAs including foxp2, tbr1, and neuroD6, and neurotransmission- and plasticity-related RNAs including sema5A, pclo, ntrk2, cntn1, and Lin7b were observed. Layer 5 motor cortex neurons of transgenic R6/2 HD mice also demonstrated numerous transcriptomic changes, including decreased expression of mRNAs encoding the Lin7 homolog b ([Lin7b] also known as veli-2 and mals2). Decreases in LIN7B and CNTN1 RNAs were also detected in human HD layer 5 motor cortex neurons. Lin7 homolog b, a scaffold protein implicated in synaptic plasticity, neurite outgrowth, and cellular polarity, was decreased at the protein level in layer 5 cortical neurons in R6/2 mice and human HD brains. Decreases in Lin7b and Lin7a mRNAs were detected in R6/2 cortex as early as 6 weeks of age, suggesting that this is an early pathogenetic event. Thus, decreased cortical LIN7 expression may contribute to abnormal corticostriatal connectivity in HD.

Repetitive head injury is also associated with the development of chronic traumatic encephalopathy (CTE), a tauopathy characterized by neurofibrillary tangles throughout the brain in the relative absence of beta-amyloid deposits. We examined 12 cases of CTE and, in 10, found a widespread TAR DNA-binding protein of approximately 43 kd (TDP-43) proteinopathy affecting the frontal and temporal cortices, medial temporal lobe, basal ganglia, diencephalon, and brainstem. Three athletes with CTE also developed a progressive motor neuron disease with profound weakness, atrophy, spasticity, and fasciculations several years before death. In these 3 cases, there were abundant TDP-43-positive inclusions and neurites in the spinal cord in addition to tau neurofibrillary changes, motor neuron loss, and corticospinal tract degeneration. The TDP-43 proteinopathy associated with CTE is similar to that found in frontotemporal lobar degeneration with TDP-43 inclusions, in that widespread regions of the brain are affected. Akin to frontotemporal lobar degeneration with TDP-43 inclusions, in some individuals with CTE, the TDP-43 proteinopathy extends to involve the spinal cord and is associated with motor neuron disease. This is the first pathological evidence that repetitive head trauma experienced in collision sports might be associated with the development of a motor neuron disease.

Modulation of voltage-gated ion channels in rat retinal ganglion cells mediated by somatostatin receptor subtype 4. J Neurophysiol 104: 1347-1354, 2010. First published June 23, 2010; doi:10.1152/jn.00098.2010. Somatostatin (somatotropin release-inhibiting factor [SRIF]) is known to modulate the excitability of retinal ganglion cells, but the membrane mechanisms responsible and the extent to which intracellular calcium signaling is affected have not been determined. We show that somatostatin receptor subtype 4 (sst(4)) is expressed specifically in rat ganglion cells and that the generation of repetitive action potentials by isolated ganglion cells is reduced in the presence of L-803,087, a selective sst(4) agonist (10 nM). Under voltage clamp, L-803,087 increased outward K+ currents by 51.1 +/- 13.1% at 0 mV and suppressed Ca2+ channel currents by 32.5 +/- 9.4% at -10 mV in whole cell patch-clamped ganglion cells. The N-type Ca2+ channel blocker omega-conotoxin GVIA (CTX, 1 mu M) reduced L-type Ca2+ current (I Ca) in ganglion cells by 43.5 +/- 7.2% at -10 mV, after which addition of L-803,087 further reduced I Ca by 28.0 +/- 16.0%. In contrast, ganglion cells treated first with nifedipine (NIF, 10 mu M), which blocked 46.1 +/- 3.5% of the control current at -10 mV, did not undergo any further reduction in I Ca in the presence of L-803,087 (-3.5 +/- 3.8% vs. NIF), showing that stimulation of sst(4) reduces Ca2+ influx through L-type Ca2+ channels. To assess the effects of sst(4) stimulation on intracellular Ca2+ levels ([Ca2+](i)) in ganglion cells, fura-2 was used to measure changes in [Ca2+](i) in response to depolarization induced by elevated [K+](o). [Ca2+](i) was increased to a lesser extent (86%) in the presence of L-803,087 compared with recordings made in the absence of the sst(4) agonist and this effect was blocked by NIF (10 mu M). Suppression of spiking and Ca2+ signaling via sst(4) may contribute to the reported neuroprotective actions of somatostatin and promote ganglion cell survival following ischemia and axonal trauma.

TI Cocaine-Induced Chromatin Remodeling Increases Brain-Derived Neurotrophic Factor Transcription in the Rat Medial Prefrontal Cortex, Which Alters the Reinforcing Efficacy of Cocaine SO JOURNAL OF NEUROSCIENCE LA English DT Article ID ADENOASSOCIATED VIRUS VECTORS; MESOLIMBIC DOPAMINE SYSTEM; GENE-EXPRESSION; BDNF-GENE; MOLECULAR-MECHANISMS; HUNTINGTONS-DISEASE; NUCLEUS-ACCUMBENS; DRUG-ADDICTION; PROTEIN-LEVELS; D-3 RECEPTOR AB Cocaine self-administration alters patterns of gene expression in the brain that may underlie cocaine-induced neuronal plasticity. In the present study, male Sprague Dawley rats were allowed to self-administer cocaine (0.25 mg/infusion) 2 h/d for 14 d, followed by 7 d of forced abstinence. Compared with yoked saline control rats, cocaine self-administration resulted in increased brain-derived neurotrophic factor (BDNF) protein levels in the rat medial prefrontal cortex (mPFC). To examine the functional relevance of this finding, cocaine self-administration maintained under a progressive ratio schedule of reinforcement was assessed after short hairpin RNA-induced suppression of BDNF expression in the mPFC. Decreased BDNF expression in the mPFC increased the cocaine self-administration breakpoint. Next, the effect of cocaine self-administration on specific BDNF exons was assessed; results revealed selectively increased BDNF exon IV-containing transcripts in the mPFC. Moreover, there were significant cocaine-induced increases in acetylated histone H3 (AcH3) and phospho-cAMP response element binding protein (pCREB) association with BDNF promoter IV. In contrast, there was decreased methyl-CpG-binding protein 2 (MeCP2) association with BDNF promoter IV in the mPFC of rats that previously self-administered cocaine. Together, these results indicate that cocaine-induced increases in BDNF promoter IV transcript in the mPFC are driven by increased binding of AcH3 and pCREB as well as decreased MeCP2 binding at this BDNF promoter. Collectively, these results indicate that cocaine self-administration remodels chromatin in the mPFC, resulting in increased expression of BDNF, which appears to represent a compensatory neuroadaptation that reduces the reinforcing efficacy of cocaine.

We now report that, in intact hippocampi prepared from neonatal rats and transgenic mice expressing Clomeleon, recurrent seizures progressively increase the intracellular chloride concentration ([Cl(-)](i)) assayed by Clomeleon imaging and invert the net effect of GABA(A) receptor activation from inhibition to excitation assayed by the frequency of action potentials and intracellular Ca(2+) transients. These changes correlate with increasing frequency of seizure-like events and reduction in phenobarbital efficacy. The Na(+)-K(+)-2Cl(-) (NKCC1) cotransporter blocker bumetanide inhibited seizure-induced neuronal Cl(-) accumulation and the consequent facilitation of recurrent seizures. Our results demonstrate a novel mechanism by which seizure activity leads to [Cl(-)](i) accumulation, thereby increasing the probability of subsequent seizures. This provides a potential mechanism for the early crescendo phase of neonatal seizures.

Changes in capillary permeability result in the extravasation of extracellular fluid, inflammatory cells, and blood, thereby producing cerebral edema, inflammation, and progressive secondary hemorrhage (PSH). Recent work in rat models of TBI and stroke have implicated 2 ion transport proteins expressed in brain endothelial cells as critical mediators of edema formation: the constitutively expressed Na(+)-K(+)-2Cl(-) cotransporter, NKCC1, and the trauma/ischemia-induced SUR1-regulated NC(Ca-ATP) (SUR1/TRPM4) channel. Whereas NKCC1 function requires adenosine 5'-triphosphate (ATP), activation of SUR1/TRPM4 occurs only after ATP depletion. This opposite dependence on intracellular ATP levels implies that one or the other mechanism will activate/deactivate as ATP concentrations rise and fall during periods of ischemia/reperfusion, resulting in continuous edema formation regardless of cellular energy status. Moreover, with critical ATP depletion, sustained opening of SUR1/TRPM4 channels results in the oncotic death of endothelial cells, leading to capillary fragmentation and PSH. Bumetanide and glibenclamide are 2 well-characterized, safe, FDA-approved drugs that inhibit NKCC1 and the SUR1/TRPM4 channel, respectively. When used alone, these drugs have provided documented beneficial effects in animal models of TBI- and ischemia-associated cerebral edema and PSH. Given the mechanistic and temporal differences by which NKCC1 and the SUR1/TRPM4 channel contribute to the pathophysiological mechanisms of these events, combination therapy with bumetanide and glibenclamide may yield critical synergy in preventing injury-associated capillary failure.

Gregory TI Toward Implementing an MRI-Based PET Attenuation-Correction Method for Neurologic Studies on the MR-PET Brain Prototype SO JOURNAL OF NUCLEAR MEDICINE LA English DT Article DE simultaneous MR-PET; attenuation correction; ultrashort echo time MRI sequence; brain imaging; head segmentation ID POSITRON-EMISSION-TOMOGRAPHY; 3D PET; SEGMENTATION; PET/MRI; BONE AB Several factors have to be considered for implementing an accurate attenuation-correction (AC) method in a combined MR-PET scanner. In this work, some of these challenges were investigated, and an AC method based entirely on the MRI data obtained with a single dedicated sequence was developed and used for neurologic studies performed with the MR-PET human brain scanner prototype. Methods: The focus was on the problem of bone-air segmentation, selection of the linear attenuation coefficient for bone, and positioning of the radiofrequency coil. The impact of these factors on PET data quantification was studied in simulations and experimental measurements performed on the combined MR-PET scanner. A novel dual-echo ultrashort echo time (DUTE) MRI sequence was proposed for head imaging. Simultaneous MR-PET data were acquired, and the PET images reconstructed using the proposed DUTE MRI-based AC method were compared with the PET images that had been reconstructed using a CT-based AC method. Results: Our data suggest that incorrectly accounting for the bone tissue attenuation can lead to large underestimations (>20%) of the radiotracer concentration in the cortex. Assigning a linear attenuation coefficient of 0.143 or 0.151 cm(-1) to bone tissue appears to give the best trade-off between bias and variability in the resulting images. Not identifying the internal air cavities introduces large overestimations (>20%) in adjacent structures. On the basis of these results, the segmented CT AC method was established as the silver standard for the segmented MRI-based AC method. For an integrated MR-PET scanner, in particular, ignoring the radiofrequency coil attenuation can cause large underestimations (i.e., <= 50%) in the reconstructed images. Furthermore, the coil location in the PET field of view has to be accurately known. High-quality bone-air segmentation can be performed using the DUTE data. The PET images obtained using the DUTE MRI- and CT-based AC methods compare favorably in most of the brain structures. Conclusion: A DUTE MRI-based AC method considering all these factors was implemented. Preliminary results suggest that this method could potentially be as accurate as the segmented CT method and could be used for quantitative neurologic MR-PET studies.

The objective of this study was to investigate the association of aggregation (condensation) of mesenchymal stem cell (MSCs) and chondrogenesis in vitro. Previous work with chondrocytes indicated that the cross-link density and related cell-mediated contraction of collagen scaffolds significantly affects cartilaginous tissue formation within the cell-seeded construct. Based on this finding, we hypothesized that the cell-aggregating effect of the contraction of MSC-seeded collagen scaffolds of lower cross-link density favors chondrogenesis; scaffolds of higher cross-link density, which resist cell-mediated contraction, would demonstrate a lower cell number density (i.e., subcritical packing density) and less cartilage formation. Type II collagen GAG scaffolds, chemically cross-linked to achieve a range of cross-link densities, were seeded with caprine MSCs and cultured for 4 weeks. Constructs with low cross-link densities experienced cell-mediated contraction, increased cell number densities, and a greater degree of chondrogenesis (indicated by the chondrocytic morphology of cells, and synthesis of GAG and type II collagen) compared to more highly cross-linked scaffolds that resisted cellular contraction. These results provide a foundation for further investigation of the mechanisms by which condensation of mesenchymal cells induces chondrogenesis in this in vitro model, and may inform cross-linking protocols for collagen scaffolds for use in cartilage tissue engineering.

TI Carboxy Terminus of Secreted Phosphoprotein-24 kDa (spp24) Is Essential for Full Inhibition of BMP-2 Activity SO JOURNAL OF ORTHOPAEDIC RESEARCH LA English DT Article DE bone morphogenetic proteins; BMP-binding proteins; surface plasmon resonance; spp24 ID BONE MORPHOGENETIC PROTEINS; BINDING PEPTIDE; ANTAGONISTS; SEQUENCE; GENE AB Secreted phosphoprotein-24 kDa (spp24) is a bone morphogenetic protein (BMP)-binding protein isolated from bone. It exists in a number of size forms and is hypothesized to function as a BMP latency protein and/or a "slow release" mechanism for BMPs involved in bone turnover and repair. We have examined the hypothesis that proteolytic modification of the C-terminus of spp24 affects its BMP-2-binding properties and bioactivity in the BMP-2-stimulated ectopic bone forming bioassay. Three different size forms of recombinant spp24 that correspond to predicted 18.1 kDa, 16.0 kDa, and 14.5 kDa proteolytic products were compared to full-length (fl) spp24. One of these forms (spp18.1) we hypothesize to be the protein which Urist initially, but apparently inaccurately, called "BMP." Only full-length spp24 completely inhibited BMP-2-induced bone formation. The 18.1 kD a truncated isoform of spp24 which we hypothesize to be Urist's protein did not. The inhibitory capacity of the proteins was correlated with their kinetic constants, assessed by surface plasmon resonance. At the highest, inhibitory, dose of spp24 and its derivatives, k(d) ("stability") best predicted the extent of ectopic bone formation whereas at the lowest dose, which was not inhibitory, k(a) ("recognition") best predicted the extent of ectopic bone formation. We conclude that proteolytic processing of spp24 affects the interaction of this protein with BMP-2 and this affects the function of the protein. (C) 2010 Orthopaedic Research Society.

TI Opioid Pharmacotherapy for Chronic Non-Cancer Pain in the United States: A Research Guideline for Developing an Evidence-Base SO JOURNAL OF PAIN LA English DT Article DE Opioid pharmacotherapy; chronic pain; evidence-based medicine; guideline; effectiveness; efficacy ID CHRONIC NONMALIGNANT PAIN; LOW-BACK-PAIN; CLINICAL-PRACTICE GUIDELINE; PRIMARY-CARE PHYSICIANS; DRUG-RELATED BEHAVIORS; TORSADES-DE-POINTES; INDUCED HYPERALGESIA; MORPHINE REQUIREMENTS; WORKERS-COMPENSATION; RANDOMIZED-TRIALS AB This document reports the consensus of an interdisciplinary panel of research and clinical experts charged with reviewing the use of opioids for chronic noncancer pain (CNCP) and formulating guidelines for future research. Prescribing opioids for chronic noncancer pain has recently escalated in the United States. Contrasting with increasing opioid use are: 1) The lack of evidence supporting long-term effectiveness; 2) Escalating misuse of prescription opioids including abuse and diversion; and 3) Uncertainty about the incidence and clinical salience of multiple, poorly characterized adverse drug events (ADEs) including endocrine dysfunction, immunosuppression and infectious disease, opioid-induced hyperalgesia and xerostomia, overdose, falls and fractures, and psychosocial complications. Chief among the limitations of current evidence are: 1) Sparse evidence on long-term opioid effectiveness in chronic pain patients due to the short-term time frame of clinical trials; 2) Insufficiently comprehensive outcome assessment; and 3) Incomplete identification and quantification of ADEs. The panel called for a strategic interdisciplinary approach to the problem domain in which basic scientists and clinicians cooperate to resolve urgent issues and generate a comprehensive evidence base. It offered 4 recommendations in 3 areas: 1) A research strategy for studying the effectiveness of long-term opioid pharmacotherapy; 2) Improvements in evidence-generation methodology; and 3) Potential research topics for generating new evidence. Perspective: Prescribing opioids for CNCP has outpaced the growth of scientific evidence bearing on the benefits and harms of these interventions. The need for a strong evidence base is urgent. This guideline offers a strategic approach to creating a comprehensive evidence base to guide safe and effective management of CNCP. (C) 2010 by the American Pain Society C1 [Chapman, C.

TI The Association of Single Nucleotide Polymorphisms in the Catechol-O-Methyltransferase Gene and Pain Scores in Female Patients With Major Depressive Disorder SO JOURNAL OF PAIN LA English DT Article DE COMT; visual analog scale; pain sensitivity; MDD; gender ID HAPLOTYPES; PERCEPTION; EXPRESSION AB We tested the hypothesis that single nucleotide polymorphisms (SNPs) in the catechol-O-methyltransferase (COMT) gene are associated with baseline pain levels in patients with major depressive disorder (MDD). Pain levels were quantified using a visual analog scale (VAS) for pain. Data from 159 female and 93 male self-reported white patients with MDD were analyzed. The associations between a haplotype previously associated with pain sensitivity created using COMT SNPs rs6269, rs4633, rs4818, and rs4680, and the proportion of female patients with "Pain While Awake" and "Overall Pain" at baseline were statistically significant (P < .05). In male patients, no statistically significant associations between COMT haplotypes and baseline pain scores were seen. The rs165599 SNP, which has previously been associated with response of depressive symptoms to treatment in patients with MDD, did not impact baseline pain in either gender. In conclusion, baseline pain levels appear to be associated with the COMT pain sensitivity haplotype in female patients with MDD. Perspective: This article presents associations of the COMT pain sensitivity haplotype and baseline pain levels in female patients with MDD. This finding could potentially help clinicians who seek to assess how genetic polymorphisms may contribute to a patient's pain experience.

We expanded the precursor definition to all secretory cell outgrowths (SCOUTs) of 30 or more cells and scored normal (N) and altered (A) expression of both p53 and PAX2, a gene down-regulated in ovarian and endometrial cancer. SCOUTs were identified by BCL2/p73 staining in tubes from women with serous carcinoma, inherited mutations in BRCA1 or BRCA2 and controls. SCOUTs were prevalent in both proximal and distal tube and significantly associated with serous carcinoma versus the others (p < 0.001); 89% were PAX2 (A) and 26% were PAX2 (A)/p53 (A) (p53 signatures). PAX2 (A)/p53 (N) SCOUTs were free of p53 mutations; however, 12 of 13 p53 signatures were PAX2 (A). A tubal carcinoma and contiguous SCOUT were p53 (A)/PAX2 (A) and shared the same p53 mutation. SCOUTs are discretely localized alterations commonly containing altered expression of multiple genes within histologically benign tubal epithelium. Geographic distribution in the tube varies by genotype and immunophenotype, from regionally unrestricted (PAX2) to greater likelihood specific area (fimbria) of shared prevalence (PAX2 and p53). This study reveals, for the first time, an entity (SCOUT) that is associated with serous cancer, expands the topography of altered PAX2 expression in the female genital tract mucosa and highlights another potential pathway disturbance involved in early serous carcinogenesis in the Fallopian tube.

Comprehensive biochemical profiling (metabolomics) has become a powerful tool for disease characterization and biomarker discovery. In a previous study, we performed a metabolomic analysis of gingival crevicular fluid collected from healthy, gingivitis, and periodontitis sites. Many metabolites associated with inflammation, oxidative stress, tissue degradation, and bacterial metabolism were found to be significantly induced by the diseases. Methods: A panel of 10 markers was selected from the previous metabolomic study based on their statistical significance. Thirty-nine chronic periodontitis subjects were randomly assigned to a toothpaste regimen: control dentifrice (n = 21) or triclosan-containing dentifrice ([CT] n = 18). Subjects were instructed to use their assigned dentifrice twice daily for 6 weeks. Gingival crevicular fluid samples from six healthy, six gingivitis, and three periodontitis sites were collected from each subject at baseline, 1 week, and 6 weeks. The relative levels of the markers in the samples were determined by mass spectrometry. One-sided matched-paired t tests were performed to compare data from healthy, gingivitis, and periodontitis sites. Results: Statistical analysis indicates that CT significantly decreased the levels of inosine, lysine, putrescine, and xanthine at the gingivitis sites as early as week 1. In contrast, control dentifrice had little effect. Conclusions: This result provides biochemical confirmation for the therapeutic effects of CT on gingivitis. Biomarkers were significantly altered by CT before clinical changes were observed, suggesting that the markers have predicative value for disease state assessment. J Periodontol 2010;81:12731279.

Elastase activity was assessed by an enzymatic assay. Subgingival plaque samples were analyzed using checkerboard DNA-DNA hybridization. Significance of differences among groups for immunologic and microbiologic data was examined using Kruskal-Wallis adjusting for multiple comparisons. Results: Mean clinical parameters and GCF volumes were higher in patients with GCP and GAgP compared to the gingivitis group. Higher levels of IL-1 beta and higher elastase activity were found in deep sites compared to shallow sites in both periodontitis groups (P<0.05). The microbiologic data showed significantly higher levels of the red complex species in patients with GCP and GAgP compared to gingivitis (P<0.05). There were no statistically significant differences in levels of GCF biomarkers and in levels of subgingival bacterial species between subjects with GCP and GAgP. Conclusion: There were no statistically significant differences in the measured immunologic and microbiologic parameters between subjects with GCP and GAgP. J Periodontol 2010;81:1308-1316.

CA Inflammation Host Response Injury TI Plasma Proteome Response to Severe Burn Injury Revealed by O-18-Labeled "Universal" Reference-Based Quantitative Proteomics SO JOURNAL OF PROTEOME RESEARCH LA English DT Article DE human plasma; quantitative proteomics; O-18 labeling; LC-MS; burn; inflammation; "universal" reference ID CHROMATOGRAPHY-MASS SPECTROMETRY; TIME TAG APPROACH; LIQUID-CHROMATOGRAPHY; METABOLIC-RESPONSE; ORGAN DYSFUNCTION; ACCURATE MASS; EXPRESSION; INFLAMMATION; ACTIVATION; LIPOPOLYSACCHARIDE AB A burn injury represents one of the most severe forms of human trauma and is responsible for significant mortality worldwide. Here, we present the first quantitative proteomics investigation of the blood plasma proteome response to severe burn injury by comparing the plasma protein concentrations of 10 healthy control subjects with those of 15 severe burn patients at two time-points following the injury. The overall analytical strategy for this work integrated immunoaffinity depletion of the 12 most abundant plasma proteins with cysteinyl-peptide enrichment-based fractionation prior to LC-MS analyses of individual patient samples. Incorporation of an O-18-labeled "universal" reference among the sample sets enabled precise relative quantification across samples. In total, 313 plasma proteins confidently identified with two or more unique peptides were quantified. Following statistical analysis, 110 proteins exhibited significant abundance changes in response to the burn injury. The observed changes in protein concentrations suggest significant inflammatory and hypermetabolic response to the injury, which is supported by the fact that many of the identified proteins are associated with acute phase response signaling, the complement system, and coagulation system pathways. The regulation of similar to 35 proteins observed in this study is in agreement with previous results reported for inflammatory or burn response, but approximately 50 potentially novel proteins previously not known to be associated with burn response or inflammation are also found. Elucidating proteins involved in the response to severe burn injury may reveal novel targets for therapeutic interventions as well as potential predictive biomarkers for patient outcomes such as multiple organ failure.

TI The Psychometric Properties of the Personality Assessment Inventory-Short Form (PAI-SF) in Inpatient Forensic and Civil Samples SO JOURNAL OF PSYCHOPATHOLOGY AND BEHAVIORAL ASSESSMENT LA English DT Article DE Personality Assessment Inventory short-form; PAI-SF; Psychometric; Forensic assessment ID PCL-R; RELIABILITY; DISORDERS; INMATES; SCALES AB Research focusing on the Personality Assessment Inventory (PAI) has increased substantially over the past decade. However, there has been relatively little focus on the PAI short-form (PAISF). The current study evaluated the psychometric characteristics of the PAI-SF clinical scales using participants admitted to a large northeastern hospital under forensic (N = 178) and civil (N = 320) statutes. Results indicate that the internal consistency of the PAI-SF clinical scales is adequate for both the Forensic (range of alphas: 0.74 to 0.88) and Civil (0.79 to 0.91) samples, and assumptions of item-scale convergence and divergence were generally met with some exceptions. Finally, the PAI-SF exhibited strong agreement with the full-form PAI scores overall, and at the upper extreme (T a parts per thousand yenaEuro parts per thousand 70) of the distributions for both samples. The results are discussed in terms of how they extend prior research on the PAI-SF.

College students (N = 173) were randomly assigned to view one of three videos describing AN as the product of either biology, culture, or an interaction of the two. In general, those who viewed the interaction video exhibited less stigma than those who viewed the sociocultural video, though more than those who viewed the biological video. These findings are consistent with attribution theory, as well as previous empirical findings, and may represent a preliminary step towards guiding those conducting campaigns to destigmatize eating disorders.

This study evaluated an electronic alcohol-counseling clinical reminder at a single Veterans Affairs general medicine clinic. Method: The systems-level intervention evaluated in this study consisted of making the clinical reminder, which facilitated medical record documentation of brief intervention among patients who screened positive for unhealthy alcohol use, available to providers on one (of two) randomly selected hallways. Secondary electronic data were extracted for all patients who visited the clinic (October 1, 2002, to September 30, 2005). The proportion of patients with clinical-reminder use was evaluated among patients who screened positive for unhealthy drinking and were assigned to intervention hallway providers ("descriptive cohort"). Adjusted logistic regression evaluated the association between the intervention and resolution of unhealthy drinking at follow-up among all screen-positive patients who completed a second Alcohol Use Disorders Identification Test Consumption questionnaire 18 months or longer after the first ("outcomes cohort"). Results: Eligible patients (N = 22,863) included 10,392 controls and 12,471 in the intervention group. Fifteen percent (398 of 2,640) of descriptive cohort patients with unhealthy drinking had clinical-reminder use, which varied by severity (14% [n = 302 of 2,165] with mild/moderate and 20% [n = 96 of 475] with severe unhealthy drinking, p = .001). Only 39% (156 of 398) of patients with clinical-reminder use had documented brief intervention; advice to abstain was most common. Access to the clinical reminder was not significantly associated with resolution of unhealthy drinking in 1,358 patients in the outcomes cohort. Conclusions: Availability of a clinical reminder to facilitate brief intervention did not, alone, result in substantial use of the clinical reminder. More active implementation efforts may be needed to get brief interventions onto the agenda of busy primary care providers. (J. Stud.

Obesity is a well-known risk factor for coronary artery disease. The objective of our study was to examine the impact of obesity on long-term survival after coronary artery bypass grafting (CABG). Materials and Methods. Using prospectively gathered data, we reviewed records of 1163 consecutive patients who underwent isolated primary CABG between 1997 and 2007. We compared outcomes of obese patients (body mass index [BMI] >= 30 kg/m(2); n = 472) and non-obese patients (BMI < 30 kg/m(2); n = 691). Long-term survival was assessed by using Kaplan-Meier curves generated by log-rank tests and adjusted for confounding factors with Cox logistic regression analysis. Results. Obese patients were slightly younger (60 +/- 8 versus 63 +/- 9y; P < 0.0001), were less likely to be current tobacco smokers (30% versus 41%; P < 0.0001), had a higher incidence of diabetes (51% versus 33%; P < 0.0001), and had a lower incidence of cerebral vascular disease (18% versus 24%; P = 0.009) than non-obese patients. The two groups of patients had similar 30-d rates of mortality (1.3% versus 1.5%; P = 0.8) and major adverse cardiac events (2.3% versus 2.5%; P = 0.9). Adjusted Cox regression survival curves were also similar between the two groups of patients (adjusted hazard ratio, 1.2; 95% confidence interval, 0.8-1.8; P = 0.28). Conclusions. Obese patients who underwent CABG had 30-d mortality rates and early outcomes similar to those of non-obese patients. Long-term survival was also similar between these two groups of patients after adjustment for confounding variables. Published by Elsevier Inc.

TI Pharmacologic Resuscitation Promotes Survival and Attenuates Hemorrhage-Induced Activation of Extracellular Signal-Regulated Kinase 1/2 SO JOURNAL OF SURGICAL RESEARCH LA English DT Article; Proceedings Paper CT 5th Annual Academic-Surgical Congress CY JAN-FEB -, 2010 CL San Antonio, TX DE hemorrhage; shock; resuscitation; valproic acid; acetylation; survival; ERK; lung ID HISTONE DEACETYLASE INHIBITORS; FOCAL CEREBRAL-ISCHEMIA; INDUCED CELL-DEATH; VALPROIC ACID; FLUID RESUSCITATION; CARDIAC HISTONES; PROTEIN-KINASES; LUNG INJURY; SHOCK; ACETYLATION AB Background. Hemorrhage is the leading cause of preventable trauma-related deaths, and histone deacetylase inhibitors (HDACI) such as valproic acid (VPA) can improve survival following lethal hemorrhage. HDACI acetylate proteins, and acetylation regulates many cellular functions. Here we have investigated the effects of VPA treatment on extracellular signal-regulated kinase 1/2 (ERK) activation, as ERK is well known to modulate cell death, gene expression, and inflammation. Materials and Methods. Anesthetized Wistar-Kyoto rats were subjected to lethal (60%) blood loss, and then randomized (n = 5-6/group) to (1) VPA 300 mg/kg or (2) vehicle control. Survival was monitored for 24 h. A separate group of rats were subjected to sublethal (40%) hemorrhage and were treated with VPA or vehicle. Rats were sacrificed at 1, 4, and 20 h, and lung tissue was assessed for the degree of acetylation of histone 3, and activation (phosphorylation) of ERK. Sham animals served as normal controls. Results. Sixty percent hemorrhage resulted in severe shock. Only 17% of the vehicle-treated animals survived (most died within 1 h), whereas 80% of the VPA-treated animals survived (P < 0.05). Hemorrhage resulted in a significant increase in phosphorylated ERK (activated form) compared with sham at the 1 and 4 h time points, but not at the 20 h time point. VPA treatment significantly attenuated these changes, while increasing histone protein acetylation. Conclusions. VPA treatment significantly improves survival following lethal hemorrhagic shock. Hemorrhage induces ERK activation, which is significantly attenuated by VPA treatment. This may represent one mechanism through which VPA promotes survival in otherwise lethal hemorrhagic shock.

TI Treatment with Histone Deacetylase Inhibitor Attenuates MAP Kinase Mediated Liver Injury in a Lethal Model of Septic Shock SO JOURNAL OF SURGICAL RESEARCH LA English DT Article; Proceedings Paper CT 5th Annual Academic-Surgical Congress CY JAN-FEB -, 2010 CL San Antonio, TX DE septic shock; acetylation; LPS; suberoylanilide hydroxamic acid; histone; MAP kinase; p38; ERK; IL-10; IL-6; liver ID TUMOR-NECROSIS-FACTOR; SUBEROYLANILIDE HYDROXAMIC ACID; CRITICALLY ILL PATIENTS; PROTEIN-KINASE; TNF-ALPHA; RESUSCITATION STRATEGIES; SIGNAL-TRANSDUCTION; CYTOKINE PRODUCTION; HUMAN ENDOTOXEMIA; CARDIAC HISTONES AB Background. Despite global efforts to improve the treatment of sepsis, it remains a leading cause of morbidity and mortality in intensive care units. We have previously shown that suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, markedly improves survival in a murine model of lipopolysaccharide (LPS) -induced shock. SAHA has anti-inflammatory properties that have not been fully characterized. The liver plays an important role in the production of acute phase reactants involved in the inflammatory cascade and is also one of the major organs that can become dysfunctional in septic shock. The purpose of this study was to assess the effect of SAHA treatment on MAP kinases and associated inflammatory markers in murine liver after LPS-induced injury. Methods. C57B1/6J mice were randomly divided into three groups: (A) experimental-given intraperitoneal (i.p.) SAHA (50 mg/kg) in dimethyl sulfoxide (DMSO) vehicle solution (n = 12); (B) control- given vehicle only (n = 12), and; (C) sham-given no treatment (n = 7). Two hours later, experimental and control mice were injected with LPS (20 mg/kg, i.p.) and experimental mice received a second dose of SAHA. Livers were harvested at 3, 24, and 48 h for analysis of inflammatory markers using Western Blot, Polymerase Chain Reaction (PCR), and Enzyme-Linked Immunosorbent Assay (ELISA) techniques. Results. After 3 h, the livers of animals treated with SAHA showed significantly (P < 0.05) decreased expression of the pro-inflammatory MAP kinases phosphorylated p38, phosphorylated ERK, myeloperoxidase and interleukin-6, and increased levels of the anti-inflammatory interleukin-10 compared with controls. Phospho-p38 expression remained low in the SAHA treated groups at 24 and 48 h. Conclusion. Administration of SAHA is associated with attenuation of MAPK activation and alteration of inflammatory and anti-inflammatory markers in murine liver after a lethal LPS insult. The suppression of MAPK activity is rapid (within 3 h), and is sustained for up to 48 h post-treatment. These results may in part account for the improvement in survival shown in this model.

TI Impact of Spectrally Asynchronous Delays on Consonant Voicing Perception SO JOURNAL OF THE AMERICAN ACADEMY OF AUDIOLOGY LA English DT Article DE Assistive listening devices; hearing aids; speech perception ID HEARING-AID DELAYS; SPEECH PRODUCTION; IMPAIRED SUBJECTS; STOP CONSONANTS; LIMITS; IDENTIFICATION; RECOGNITION; SENTENCES; ENGLISH; ADULTS AB Background: A possible voicing cue used to differentiate voiced and voiceless cognate pairs is envelope onset asynchrony (EOA). EOA is the time between the onsets of two frequency bands of energy (in this study one band was high-pass filtered at 3000 Hz, the other low-pass filtered at 350 Hz). This study assessed the perceptual impact of manipulating EOA on voicing perception of initial stop consonants, and whether normal-hearing and hearing-impaired listeners were sensitive to changes in EOA as a cue for voicing. Purpose: The purpose of this study was to examine the effect of spectrally asynchronous auditory delay on the perception of voicing associated with initial stop consonants by normal-hearing and hearing-impaired listeners. Research Design: Prospective experimental study comparing the perceptual differences of manipulating the EOA cues for two groups of listeners. Study Sample: Thirty adults between the ages of 21 and 60yr completed the study: 17 listeners with normal hearing and 13 listeners with mild-moderate sensorineural hearing loss. Data Collection and Analysis: The participants listened to voiced and voiceless stop consonants within a consonant-vowel syllable structure. The EOA of each syllable was varied along a continuum, and identification and discrimination tasks were used to determine if the EOA manipulation resulted in categorical shifts in voicing perception. In the identification task the participants identified the consonants as belonging to one of two categories (voiced or voiceless cognate). They also completed a same-different discrimination task with the same set of stimuli. Categorical perception was confirmed with a d-prime sensitivity measure by examining how accurately the results from the identification task predicted the discrimination results. The influence of EOA manipulations on the perception of voicing was determined from shifts in the identification functions and discrimination peaks along the EOA continuum. The two participant groups were compared in order to determine the impact of EOA on voicing perception as a function of syllable and hearing status. Results: Both groups of listeners demonstrated a categorical shift in voicing perception with manipulation of EOA for some of the syllables used in this study. That is, as the temporal onset asynchrony between low-and high-frequency bands of speech was manipulated, the listeners' perception of consonant voicing changed between voiced and voiceless categories. No significant differences were found between listeners with normal hearing and listeners with hearing loss as a result of the EOA manipulation. Conclusions: The results of this study suggested that both normal-hearing and hearing-impaired listeners likely use spectrally asynchronous delays found in natural speech as a cue for voicing distinctions. While delays in modern hearing aids are less than those used in this study, possible implications are that additional asynchronous delays from digital signal processing or open-fitting amplification schemes might cause listeners with hearing loss to misperceive voicing cues.

As prior genome-wide association studies (GWAS) have not yielded significant results, we conducted a meta-analysis of existing studies to boost statistical power. Method: We used data from four projects: a) the Children's Hospital of Philadelphia (CHOP); b) phase I of the International Multicenter ADHD Genetics project (IMAGE); c) phase II of IMAGE (IMAGE II); and d) the Pfizer-funded study from the University of California, Los Angeles, Washington University, and Massachusetts General Hospital (PUWMa). The final sample size consisted of 2,064 trios, 896 cases, and 2,455 controls. For each study, we imputed HapMap single nucleotide polymorphisms, computed association test statistics and transformed them to z-scores, and then combined weighted z-scores in a meta-analysis. Results: No genome-wide significant associations were found, although an analysis of candidate genes suggests that they may be involved in the disorder. Conclusions: Given that ADHD is a highly heritable disorder, our negative results suggest that the effects of common ADHD risk variants must, individually, be very small or that other types of variants, e.g., rare ones, account for much of the disorder's heritability.

However, the genetic architecture of the disorder is unknown, and prior genome-wide association studies (GWAS) have not identified a genome-wide significant association. We have conducted a third, independent, multisite GWAS of DSM-IV-TR ADHD. Method: Families were ascertained at Massachusetts General Hospital (MGH; N = 309 trios), Washington University at St. Louis (WASH-U; N = 272 trios), and University of California at Los Angeles (UCLA; N = 156 trios). Genotyping was conducted with the Illumina Human1M or Human1M-Duo Bead Chip platforms. After applying quality control filters, association with ADHD was tested with 835,136 SNPs in 735 DSM-IV ADHD trios from 732 families. Results: Our smallest p value (6.7E-07) did not reach the threshold for genome-wide statistical significance (5.0E-08), but one of the 20 most significant associations was located in a candidate gene of interest for ADHD (SLC9A9, rs9810857, p = 6.4E-6). We also conducted gene-based tests of candidate genes identified in the literature and found additional evidence of association with SLC9A9. Conclusions: We and our colleagues in the Psychiatric GWAS Consortium are working to pool together GWAS samples to establish the large data sets needed to follow-up on these results and to identify genes for ADHD and other disorders.

Thus additional genomewide association studies (GWAS) are needed. Method: We used case-control analyses of 896 cases with DSM-IV ADHD genotvped using the Affymetrix 5.0 array and 2,455 repository controls screened for psychotic and bipolar symptoms genotyped using Affymetrix 6.0 arrays. A consensus SNP set was imputed using BEAGLE 3.0, resulting in an analysis dataset of 1,033,244 SNPs. Data were analyzed using a generalized linear model. Results: No genomewide significant associations were found. The most significant results implicated the following genes: PRKG1, FLNC, TCERG1L, PPM1H, NXPH1, PPM1H, CDH13, HK1, and HKDC1. Conclusions: The current analyses are a useful addition to the present literature and will make a valuable contribution to future meta-analyses. The candidate gene findings are consistent with a prior meta-analysis in suggesting that the effects of ADHD risk variants must, individually, be very small and/or include multiple rare alleles. J.

Although similar cognitive deficits have been identified in pediatric OCD, few neuroimaging studies have been conducted to examine its neural correlates in the developing brain. In this study, we tested hypotheses regarding group differences in the behavioral and neural correlates of cognitive flexibility in a pediatric OCD and a healthy comparison (HC) sample. Method: In this functional magnetic resonance imaging (fMRI) study, a pediatric sample of 10- to 17-year-old subjects, 15 with OCD and 20 HC, completed a set-shifting task. The task, requiring an extradimensional shift to identify a target, examines cognitive flexibility. Within each block, the dimension (color or shape) that identified the target either alternated (i.e., mixed) or remained unchanged (i.e., repeated). Results: Compared with the HC group, the OCD group tended to be slower to respond to trials within mixed blocks. Compared with the HC group, the OCD group exhibited less left inferior frontal gyrus/BA47 activation in the set-shifting contrast (i.e., HC > OCD, mixed versus repeated); only the HC group exhibited significant activation in this region. The correlation between set shifting-induced right caudate activation and shift cost (i.e., reaction time differential in response to mixed versus repeated trials) was significantly different between HC and OCD groups, in that we found a positive correlation in HC and a negative correlation in OCD. Conclusions: In pediatric OCD, less fronto-striatal activation may explain previously identified deficits in shifting cognitive sets. J. Am. Acad. Child Adolesc. Psychiatry, 2010;49(9): 944-953.

Unlike Fanner disease, a self-limiting condition of the immature capitellum, OCD is multifactorial and likely results from microtrauma in the setting of cartilage mismatch and vascular susceptibility. The natural history of OCD is poorly understood, and degenerative joint disease may develop over time. Multiple modalities aid in diagnosis, including radiography, MRI, and magnetic resonance arthrography. Lesion size, location, and grade determine management, which should attempt to address subchondral bone loss and articular cartilage damage. Early, stable lesions are managed with rest. Surgery should be considered for unstable lesions. Most investigators advocate arthroscopic debridement with marrow stimulation. Fragment fixation and bone grafting also have provided good short-term results, but concerns persist regarding the healing potential of advanced lesions. Osteochondral autograft transplantation appears to be promising and should be reserved for larger, higher grade lesions. Clinical outcomes and return to sport are variable. Longer-term follow-up studies are necessary to fully assess surgical management, and patients must be counseled appropriately.

TI ACR Appropriateness Criteria (R) on Colorectal Cancer Screening SO JOURNAL OF THE AMERICAN COLLEGE OF RADIOLOGY LA English DT Article DE Colorectal cancer; adenoma; screening; CT colonography; barium enema; Appropriateness Criteria (R) AB Colorectal cancer remains one of the most common causes of cancer death in this country. This malignancy is ideally suited for screening because the detection and removal of the precursor adenomatous polyp can prevent most colorectal cancers from ever forming. The choice of a test for screening involves consideration of various individual parameters, including patient age and the presence of risk factors for the development of colorectal cancer. Computed tomographic colonography (CTC) has emerged as the leading imaging technique for colorectal cancer screening in average-risk individuals on the basis of the evidence presented in this paper. The double-contrast barium enema is an alternative imaging test that is appropriate particularly when CTC is not available. In 2008, the American Cancer Society guideline for colorectal cancer screening was revised jointly with the US Multi-Society Task Force on Colorectal Cancer and the ACR to include CTC every 5 years as an option for average-risk individuals. Computed tomographic colonography is also the preferred test for colon evaluation after an incomplete colonoscopy. Imaging tests including CTC and the double-contrast barium enema are usually not indicated for colorectal cancer screening in high-risk patients with polyposis syndromes or inflammatory bowel disease. This paper presents the new colorectal cancer imaging test ratings and is the result of evidence-based consensus by the ACR Appropriateness Criteria (R) Expert Panel on Gastrointestinal Imaging.

TI The Impact of an Early-Morning Radiologist Work Shift on the Timeliness of Communicating Urgent Imaging Findings on Portable Chest Radiography SO JOURNAL OF THE AMERICAN COLLEGE OF RADIOLOGY LA English DT Article DE Urgent finding; communication of finding; portable chest radiography; critical test results; staggered work shifts; early-morning shift AB Purpose: The aim of this study was to assess the potential impact of staggered radiologist work shifts on the timeliness of communicating urgent imaging findings that are detected on portable overnight chest radiography of hospitalized patients. Methods: The authors conducted a retrospective study that compared the interval between the acquisition and communication of urgent findings on portable overnight critical care chest radiography detected by art early-morning shift for radiologists (3 AM to 11 Am) with historical experience with a standard daytime shift (8 Am to 5 Pm) in the detection and communication of urgent findings in a similar patient population a year earlier. Results: During a 4-month period, 6,448 portable chest radiographic studies were interpreted on the early-morning radiologist shift. Urgent findings requiring immediate communication were detected in 308 (4.8%) studies. The early-morning shift of radiologists, on average, communicated these findings 2 hours earlier compared with the historical control group (P < .001). Conclusion: Staggered radiologist work shifts that include an early-morning shift can improve the timeliness of reporting urgent findings on overnight portable chest radiography of hospitalized patients.

TI Online Spaced Education Generates Transfer and Improves Long-Term Retention of Diagnostic Skills: A Randomized Controlled Trial SO JOURNAL OF THE AMERICAN COLLEGE OF SURGEONS LA English DT Article ID MEMORY; TESTS AB BACKGROUND: Retention of learning from surgical training is often limited, especially if the knowledge and skills are used infrequently. Using histopathology diagnostic skills as an experimental system, we compared knowledge transfer and retention between bolus Web-based teaching (WBT) modules and online spaced education, a novel email-based method of online education founded on the spacing effect. STUDY DESIGN: All.US urology residents were eligible to participate. Enrollees were randomized to 1 of 2 cohorts. Cohort 1 residents received 3 cycles/repetitions of spaced education on prostate-testis histopathology (weeks 1 to 16) and 3 WBT modules on bladder-kidney (weeks 14 to 16). Cohort 2 residents received 3 cycles of spaced education on bladder-kidney (weeks 1 to 16) and 3 WBT modules on prostate-testis (weeks 14 to 16). Each daily spaced education email presented a clinical scenario with histopathology image and asked for a diagnosis. Participants received immediate feedback after submitting their answers. Each cycle/repetition was 4 weeks long and consisted of 20 questions with unique images. WBT used the identical content and delivery system, with questions aggregated into three 20-question modules. Long-term retention of all 4 topics was assessed during weeks 18 to 45. RESULTS: Seven-hundred and twenty-four urology residents enrolled. Spaced education and WBT were completed by 77% and 66% of residents, respectively. Spaced education and WBT generated mean long-term score increases of 15.2% (SD 15.3%) and 3.4% (SD 16.3%), respectively (p < 0.01). Spaced education increased long-term learning efficiency 4-fold. CONCLUSIONS: Online spaced education generates transfer of histopathology diagnostic skills and substantially improves their long-term retention. Additional research is needed to determine how spaced education can optimize learning, transfer, and retention of surgical skills. ( J Am Coll Surg 2010; 211:331-337.

Sloane TI Live Transference of Surgical Subspecialty Skills Using Telerobotic Proctoring to Remote General Surgeons SO JOURNAL OF THE AMERICAN COLLEGE OF SURGEONS LA English DT Article ID COLORECTAL SURGERY; OPERATING-ROOM AB BACKGROUND: Certain clinical environments, including military field hospitals or rural medical centers, lack readily available surgical subspecialists. We hypothesized that telementoring by a surgical sub-specialist using a robotic platform is feasible and can convey subspecialty knowledge and skill to a remotely located general surgeon. STUDY DESIGN: Eight general surgery residents evaluated the effect of remote surgical telementoring by performing 3 operative procedures, first unproctored and then again when teleproctored by a surgical subspecialist. The clinical scenarios consisted of a penetrating right ventricular injury requiring suture repair, an open tibial fracture requiring external fixation, and a traumatic subdural hematoma requiring craniectomy. A robotic platform consisting of a pan-and-tilt camera with laser pointer attached to an overhead surgical light with integrated audio allowed surgical subspecialists the ability to remotely teleproctor residents. Performance was evaluated using an Operative Performance Scale. Satisfaction surveys were given after performing the scenario unproctored and again after proctoring. RESULTS: Overall mean performance scores were superior in all scenarios when residents were proctored than when they were not (4.30 +/- 0.25 versus 2.43 +/- 0.20; p < 0.001). Mean performance scores for individual metrics, including tissue handling, instrument handling, speed of completion, and knowledge of anatomy, were all superior when residents were proctored (p < 0.001). Satisfaction surveys showed greater satisfaction and comfort among residents when proctored. Proctored residents believed the robotic platform facilitated learning and would be feasible if used clinically. CONCLUSIONS: This study supports the use of surgical teleproctoring in guiding remote general surgeons by a surgical subspecialist in the care of a wounded patient in need of an emergency subspecialty operation.

TI Perceived Benefits, Barriers, and Strategies of Family Meals among Children with Type 1 Diabetes Mellitus and Their Parents: Focus-Group Findings SO JOURNAL OF THE AMERICAN DIETETIC ASSOCIATION LA English DT Article ID MEALTIME INTERACTIONS; DIETARY-INTAKE; ADOLESCENTS; PATTERNS; QUALITY AB Dietary management of type 1 diabetes mellitus has become much less restrictive and more flexible in recent years due to contemporary insulin regimens, which may afford families of children with type 1 diabetes mellitus greater ease in sharing family meals. Although these treatment advancements might facilitate family meals, overall demands of diabetes management can influence family's perceived or actual ability to do so Youths with type 1 diabetes mellitus (ages 8 to 20 years) and parents participated in separate focus groups Thirty-five youths with type 1 diabetes mellitus (mean age=15 1 +/- 3 6 years) and their parents participated in 21 focus groups (12 youth groups, nine parent groups) Although there was substantial variability in how often family meals occurred, both parents and youths consistently perceived family meals as valuable and enjoyable. The major barrier to family meals discussed by both youths and parents was busy schedules Strategies for having family meals that were discussed by parents included shopping to ensure availability of the foods needed to prepare meals, planning, and cooking meals in advance, and using simplified cooking methods. These findings suggest that a family-focused approach to nutrition interventions in this population, as opposed to one targeting the child with diabetes only, can improve the chance for successful dietary change J AM Diet Assoc. 2010,110 1302-1306.

Few studies have examined the multifaceted aspects of dietary intake of low-income, urban African-American adolescents This study aimed to describe dietary patterns including energy, nutrients, food groups, and diet quality and to identify areas to guide future interventions Baseline data for a school-based obesity prevention study were collected from 382 African-American adolescents (10- to 14-year-olds) from four Chicago, IL, public schools in 2003. Diet was assessed using a 152-item food frequency questionnaire. Diet quality was measured using a modified version of the US Department of Agriculture Healthy Eating Index (HEI) and compared to published estimates for a nationwide sample Participants reported high energy intakes and several unhealthy eating patterns 58 6% consumed one or more servings of sweetened beverages per day and 15 7% consumed three or more servings per day; average fried food consumption was high (1 4 servings/day), 58.4% consumed one or more serving per day; and 75% consumed three or more three snacks per day. Only 49% of participants met the recommended three servings of dairy foods per day. Compared to a national, mostly white sample, participants had lower HEI scores (P<0.05), mean score was 66 0=12.8 (100= maximum HEI score) vs 70 3 13 0 in boys vs girls, one third had scores <60 ("needs improvement") and only 15% scored >80 ("good") This study reveals key areas of problematic dietary patterns for future interventions targeting low-income African-American adolescents, including frequent intakes of calorie-dense, low nutrient-rich foods, such as fried foods, snacks, and sweetened beverages.

TI Greater Prevalence and Incidence of Dementia in Older Veterans with Posttraumatic Stress Disorder SO JOURNAL OF THE AMERICAN GERIATRICS SOCIETY LA English DT Article DE posttraumatic stress disorder; dementia; veterans ID ALZHEIMERS-DISEASE; RISK-FACTORS; AFFAIRS; MEMORY; PTSD; CARE; EDUCATION; INJURY; IRAQ AB OBJECTIVES To explore the association between posttraumatic stress disorder (PTSD) and dementia in older veterans. DESIGN Administrative database study of individuals seen within one regional division of the Veterans Affairs healthcare network. SETTING Veterans Integrated Service Network 16. PARTICIPANTS Veterans aged 65 and older who had a diagnosis of PTSD or who were recipients of a Purple Heart (PH) and a comparison group of the same age with no PTSD diagnosis or PH were divided into four groups: those with PTSD and no PH (PTSD+/PH-, n=3,660), those with PH and no PTSD (PTSD-/PH+, n=1,503), those with PTSD and a PH (PTSD+/PH+, n=153), and those without PTSD or a PH (PTSD-/PH-, n=5,165). MEASUREMENTS Incidence and prevalence of dementia after controlling for confounding factors in multivariate logistic regression. RESULTS The PTSD+/PH- group had a significantly higher incidence and prevalence of dementia than the groups without PTSD with or without a PH. The prevalence and incidence of a dementia diagnosis remained two times as high in the PTSD+/PH- group as in the PTSD-/PH+ or PTSD-/PH- group after adjusting for the confounding factors. There were no statistically significant differences between the other groups. CONCLUSION The incidence and prevalence of dementia is greater in veterans with PTSD. It is unclear whether this is due to a common risk factor underlying PTSD and dementia or to PTSD being a risk factor for dementia. Regardless, this study suggests that veterans with PTSD should be screened more closely for dementia. Because PTSD is so common in veterans, this association has important implications for veteran care.

DESIGN Secondary analysis of a 3.0 national field test to revise the Minimum Data Set (MDS). SETTING Seventy-one NHs in eight states. PARTICIPANTS Three thousand two hundred thirty NH residents scheduled for MDS assessments from September 2006 through February 2007. MEASUREMENTS The potentially mutable characteristics assessed were mood (Patient Health Questionnaire-9), delirium (Confusion Assessment Method), delusions, hallucinations or illusions, hearing impairment, vision impairment, pain severity, and infection diagnoses. Characteristics considered as covariates were cognition, communication abilities, and impairment in activities of daily living. RESULTS Of 3,230 residents assessed, 312 (9.7%) had demonstrated rejection of care in the preceding 5 days. In multiple regression analysis adjusted for covariates, rejection of care was associated with delusions (odds ratio (OR)=3.9; 95% confidence interval (CI)=2.5-6.0), delirium (OR=1.8, 95% CI=1.3-2.4), minor (OR=2.1, 95% CI=1.5-2.8) and major (OR=2.3, 95% CI=1.5-3.4) depression, and severe to horrible pain (OR=1.6, 95% CI=1.1-2.3). Infection diagnoses were not significant in bivariate analysis. Hallucinations or illusions, mild to moderate pain, and hearing and vision impairment were not significant in multiple regression analysis. CONCLUSION In this population, delirium, delusions, depression, and severe pain were associated with rejection of care, suggesting that some care rejection behaviors may resolve with appropriate interventions for the identified target conditions if the associations observed are causal.

This article summarizes the important issues discussed at the meeting. Historically, regulatory agencies started to promote the inclusion of older participants in clinical trials in the late 1980s. The identification of the causes of delay in including older participants in clinical trials, as well as of the ongoing bias against including older participants with multiple comorbidities, is important to help geriatricians fight against age discrimination in clinical trials. To overcome this problem, geriatrics societies and regulatory agencies must work together to propose new definitions, study designs, and technologies aimed at improving the evaluation of drugs in older people with multiple comorbidities and polypharmacy.

During a randomized controlled trial, primary care patients completed pre-visit electronic journals (eJournals) containing EHR-based medication, allergies, and diabetes (study arm 1) or health maintenance, personal history, and family history (study arm 2) topics to share with their provider. Assessment with surveys and usage data showed that among 2027 patients invited to complete an eJournal, 70.3% submitted one and 71.1% of submitters had one opened by their provider. Surveyed patients reported they felt more prepared for the visit (55.9%) and their provider had more accurate information about them (58.0%). More arm 1 versus arm 2 providers reported that eJournals were visit-time neutral (100% vs 53%; p<0.013), helpful to patients in visit preparation (66% vs 20%; p=0.082), and would recommend them to colleagues (78% vs 22%; p=0.0143). eJournal integration into practice warrants further study.

TI Medical Therapy of Diabetic Foot Infections SO JOURNAL OF THE AMERICAN PODIATRIC MEDICAL ASSOCIATION LA English DT Article ID STAPHYLOCOCCUS-AUREUS; CLASSIFICATION-SYSTEM; VALIDATION; DIAGNOSIS; RISK AB Diabetic foot infections are a common and often serious problem, accounting for more hospital bed days than any other complication of diabetes. Despite advances in antibiotic drug therapy and surgical management, these infections continue to be a major risk factor for amputations of the lower extremity. Although a variety of wound size and depth classification systems have been adapted for use in codifying diabetic foot ulcerations, none are specific to infection. In 2003, the International Working Group on the Diabetic Foot developed guidelines for managing diabetic foot infections, including the first severity scale specific to these infections. The following year, the Infectious Diseases Society of America published their diabetic foot infection guidelines. Herein, we review some of the critical points from the Executive Summary of the Infectious Diseases Society of America document and provide a commentary following each issue to update the reader on any pertinent changes that have occurred since publication of the original document in 2004. The importance of a multidisciplinary limb salvage team, apropos of this special issue jointly published by the American Podiatric Medical Association and the Society for Vascular Surgery, cannot be overstated.

TI Digoxin Associates with Mortality in ESRD SO JOURNAL OF THE AMERICAN SOCIETY OF NEPHROLOGY LA English DT Article ID IMPAIRED RENAL-FUNCTION; CHRONIC HEART-FAILURE; HEMODIALYSIS-PATIENTS; PRACTICE GUIDELINES; TASK-FORCE; DIG TRIAL; HOSPITALIZATION; MANAGEMENT; DIGITALIS; THERAPY AB The safety of prescribing digoxin in ESRD is unknown. Hypokalemia, which frequently occurs among dialysis patients, may enhance the toxicity of digoxin. Here, we analyzed the association between digoxin prescription and survival in a retrospective cohort using covariate- and propensity score adjusted Cox models to minimize the potential for confounding by indication. Among 120,864 incident hemodialysis patients, digoxin use associated with a 28% increased risk for death (hazard ratio [HR] 1.28; 95% confidence interval 1.25 to 1.31). Increasing serum digoxin level was also significantly associated with mortality (HR 1.19 per ng/ml increase; 95% confidence interval 1.05 to 1.35). This increased mortality risk with level was most pronounced in patients with lower predialysis serum potassium (K) levels (HR 2.53 [P = 0.01] for K <4.3 mEq/L versus HR 0.86 [P = 0.35] for K >4.6 mEq/L). In conclusion, digoxin use among patients who are on hemodialysis associates with increased mortality, especially among those with low predialysis K concentrations. C1 [Chan, Kevin E.; Lazarus, J.

Neuropsychological studies have generally examined each type of memory in isolation, but theorists have long argued that these two forms of memory are interdependent. Here we review several lines of neuropsychological research that have explored the interdependence of episodic and semantic memory. The studies show that these forms of memory can affect each other both at encoding and at retrieval. We suggest that theories of memory should be revised to account for all of the interdependencies between episodic and semantic memory; they should also incorporate forms of memory that do not fit neatly into either category.

TI Utility of the Neuropsychological Assessment Battery in detecting cognitive impairment after unilateral stroke SO JOURNAL OF THE INTERNATIONAL NEUROPSYCHOLOGICAL SOCIETY LA English DT Article DE Neuropsychology; Neuropsychological tests; Aging; Cerebrovascular disorders; Cognition disorders; Hemiparesis ID SCREENING MODULE; CLINICAL DETERMINANTS; PROGNOSTIC VALUE; 1ST-EVER STROKE; ISCHEMIC-STROKE; DEMENTIA; FREQUENCY; NAB; PERFORMANCE; DISORDERS AB This study evaluated the clinical utility of the Neuropsychological Assessment Battery (NAB) in a stroke sample by examining the NAB's ability to differentiate a chronic stroke group with radiologically confirmed unilateral damage (n = 42) and a demographically matched healthy control (HC) group (n = 36). The stroke group performed more poorly than the control group across NAB Total score and all five Domain scores. Receiver operator curves (ROC) were derived and area under the curve (AUC) showed moderate diagnostic effectiveness (AUC .70 to .90) for NAB Total score, all five Domain scores, a motor composite, and a Global Deficit Score (GDS) that has been shown to closely approximate clinical ratings of neuropsychological impairment. The NAB Total, GDS, and motor composite had comparable clinical utility, whereas the Attention and Executive domain scores demonstrated better classification utility compared with the Memory domain. Because 90.5% of our stroke sample had middle cerebral artery territory strokes, the comparison of motor and cognitive classification utility may be biased. However, follow-up analyses showed that the NAB accounted for additional variance even when motor composite was included in the model. Sensitivity, specificity, and odds ratios at various clinical cutoffs are provided. These results suggest that the NAB is a useful clinical tool for detection of cognitive deficits in individuals with chronic unilateral stroke, although lenient clinical cutoffs appear warranted to maximize sensitivity.

Thus, adequate design and evaluation of some immunotherapy clinical trials require a new development paradigm that includes reconsideration of established endpoints. Between 2004 and 2009, several initiatives facilitated by the Cancer Immunotherapy Consortium of the Cancer Research Institute and partner organizations systematically evaluated an immunotherapy-focused clinical development paradigm and created the principles for redefining trial endpoints. On this basis, a body of clinical and laboratory data was generated that supports three novel endpoint recommendations. First, cellular immune response assays generate highly variable results. Assay harmonization in multicenter trials may minimize variability and help to establish cellular immune response as a reproducible biomarker, thus allowing investigation of its relationship with clinical outcomes. Second, immunotherapy may induce novel patterns of antitumor response not captured by Response Evaluation Criteria in Solid Tumors or World Health Organization criteria. New immune-related response criteria were defined to more comprehensively capture all response patterns. Third, delayed separation of Kaplan-Meier curves in randomized immunotherapy trials can affect results. Altered statistical models describing hazard ratios as a function of time and recognizing differences before and after separation of curves may allow improved planning of phase III trials. These recommendations may improve our tools for cancer immunotherapy trials and may offer a more realistic and useful model for clinical investigation.

This disease is the fourth most common cause of cancer-related death among men and women in the United States. Its peak incidence is in the seventh and eighth decades of life. Although incidence is roughly equal for the sexes, African Americans seem to have a higher incidence than white Americans. Although the associated increase in risk is small, the development of pancreatic cancer is firmly linked to cigarette smoking. Some evidence shows that increased consumption of red meat and dairy products is associated with an elevation in pancreatic cancer risk, although other studies have failed to identify dietary risk factors. An increased body mass index is also associated with increased risk. Occupational exposure to chemicals, such as beta-naphthylamine and benzidine, is also associated with an increased risk of pancreatic cancer. These guidelines only discuss tumors of the exocrine pancreas; neuroendocrine tumors are not included. Important changes in the updated 2010 NCCN Guidelines include the addition of leucovorin to 5-FU chemotherapy for some cases and revised principles of diagnosis and staging.

Cancer pain or cancer-related pain is distinct from pain experienced by patients without malignancies. Pain occurs in approximately one quarter of patients with newly diagnosed malignancies, one third of patients undergoing treatment, and three quarters of patients with advanced disease, and is one of the symptoms patients fear most. Unrelieved pain denies patients comfort and greatly affects their activities, motivation, interactions with family and friends, and overall quality of life. The importance of relieving pain and availability of effective therapies make it imperative that physicians and nurses caring for these patients be adept at the assessment and treatment of cancer pain. This requires familiarity with the pathogenesis of cancer pain; pain assessment techniques; common barriers to the delivery of appropriate analgesia; and pertinent pharmacologic, anesthetic, neurosurgical, and behavioral approaches to the treatment of cancer pain. The NCCN Guidelines on adult cancer pain underwent significant revision for 2010. Noteworthy updates include the addition of steps with case examples for converting/rotating one opioid to another, oral morphine to methadone, and any opioid to transdermal fentanyl.

Methods: We examined data from 4115 veterans with a diagnosis of stroke who were seen at a VA Medical Center in the southeastern United States. We compared the receipt of physical therapy (PT) and occupational therapy (OT) evaluations, visits, and procedures among 3 racial/ethnic groups. Multiple logistic regression was used to assess the independent effect of race/ethnicity on the receipt of a PT or OT evaluation and Poisson regression to estimate the effect of race/ethnicity on treatment visits and procedures received. Results: In univariate comparisons, a higher proportion of blacks received PT and OT evaluations than whites and others. Similarly, blacks received a higher mean number of PT/OT treatments than whites and others. In multivariate logistic models with whites as reference, blacks were more likely to receive PT evaluations (odds ratio [OR], 1.47; 95% confidence interval [CI], 1.24-1.74) and OT evaluations (OR, 1.23; 95% CI, 1.01-1.51). In multivariate Poisson models with whites as reference, blacks received more PT/OT visits (OR, 7.22; 95% CI, 5.95-8.76) than non-Hispanic whites (OR, 5.28; 95% CI, 4.41-6.33), while others received fewer visits (OR, 4.39; 95% CI, 3.58-5.39) than the reference group. No significant differences were observed across groups in the number of procedures completed during each treatment visit. Conclusions: In an equal-access system, blacks were more likely to receive outpatient PT/OT evaluations and higher mean number of PT/OT treatments. Future studies need to examine sociodemographic and disease-specific factors that account for these differences.

It is hypothesized that depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder will independently contribute to an increased risk for in-hospital mortality rates after coronary artery bypass grafting surgery. Methods: We performed a retrospective analysis of the 2006 Nationwide Inpatient Sample database. The Nationwide Inpatient Sample database provides information on approximately 8 million US inpatient stays from about 1000 hospitals. We performed c 2 and unpaired t tests to evaluate potential confounding group demographic and medical variables. Hierarchic logistic regression was used with forced order entry of depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder. Results: Deceased patients were more likely to have had depression (alive, 24.8%; deceased, 60.3%; P < .001), posttraumatic stress disorder (alive, 13.4%; deceased, 56.1%; P < .001), and cormorbid depression and posttraumatic stress disorder (alive, 7.8%; deceased, 48.5%; P < .001). After adjusting for potential confounding factors, patients with depression (odds ratio, 1.24; 95% confidence interval, 1.02-1.50), posttraumatic stress disorder (odds ratio, 2.09; 95% confidence interval, 1.65-2.64), and comorbid depression and posttraumatic stress disorder (odds ratio, 4.66; 95% confidence interval, 3.46-6.26) had an increased likelihood of in-hospital mortality compared with that seen in patients who were alive. Conclusions: Two findings were noteworthy. First, depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder are prevalent in patients undergoing coronary artery bypass grafting procedures. Second, depression, posttraumatic stress disorder, and comorbid depression and posttraumatic stress disorder increase the risk of death by magnitudes comparable with well-established physical health risk factors after coronary artery bypass grafting surgery. The implications for clinical practice and future directions are discussed.

Exercise, known to worsen systolic tethering and ischemic mitral regurgitation, might also dynamically exacerbate such mitral stenosis by increasing tethering. This study evaluates the mechanism and response of such mitral stenosis to exercise. Methods: We measured the diastolic mitral valve area, annular area, and peak and mean transmitral pressure gradient by echocardiography in 20 healthy individuals and 31 patients who underwent surgical annuloplasty for ischemic mitral regurgitation. Results: Although the mitral valve area and annular area did not significantly differ in healthy individuals (4.7 +/- 0.6 cm(2) vs 5.2 +/- 0.6 cm(2), not significant), mitral valve area was significantly smaller than the annular area in patients after annuloplasty (1.6 +/- 0.2 cm(2) vs 3.3 +/- 0.5 cm(2), P < .01). The mitral valve area was less than 1.5 cm(2) only after the surgery (P < .01) and was significantly correlated with restricted leaflet opening (r(2) = 0.74, P < .001), left ventricular dilatation (r(2) = 0.17, P < .05), and New York Heart Association functional class (P < .05). Exercise stress echocardiography of 12 patients demonstrated dynamic worsening in functional mitral stenosis (mitral valve area: 2.0 +/- 0.5 cm(2) to 1.4 +/- 0.2 cm(2), P < .01; mean pressure gradient: 1.5 +/- 0.9 mm Hg to 6.0 +/- 2.2 mm Hg, P < .01). Conclusions: Persistent subvalvular leaflet tethering in the presence of annular size reduction by surgery in ischemic mitral regurgitation frequently causes functional mitral stenosis at the leaflet tip level, which is related to heart failure symptoms and can be dynamic with significant exercise-induced worsening.

TI Cellular phenotype transformation occurs during thoracic aortic aneurysm development SO JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY LA English DT Article ID MATRIX METALLOPROTEINASES; MURINE MODEL; ASCENDING AORTA; UP-REGULATION; EXPRESSION; INHIBITORS; PATTERNS; VALVES; CELLS AB Objective: Thoracic aortic aneurysms result from dysregulated remodeling of the vascular extracellular matrix, which may occur as a result of altered resident cellular function. The present study tested the hypothesis that aortic fibroblasts undergo a stable change in cellular phenotype during thoracic aortic aneurysm formation. Methods: Primary murine aortic fibroblasts were isolated from normal and thoracic aortic aneurysm-induced aortas (4 weeks post induction with 0.5 mol/L CaCl(2) 15 minutes) by the outgrowth method. Normal and thoracic aortic aneurysm cultures were examined using a focused polymerase chain reaction array to determine fibroblast-specific changes in gene expression in the absence and presence of biological stimulation (endothelin-1, phorbol-12-myristate-13-acetate, angiotensin-II). The relative expression of 38 genes, normalized to 4 housekeeping genes, was determined, and genes displaying a minimum 2-fold increase/decrease or genes with significantly different normalized cycle threshold values were considered to have altered expression. Results: At steady state, thoracic aortic aneurysm fibroblasts revealed elevated expression of several matrix metalloproteinases (Mmp2, Mmp11, Mmp14), collagen genes/elastin (Col1a1, Col1a2, Col3a1, Eln), and other matrix proteins, as well as decreased expression of Mmp3, Timp3, and Ltbp1. Moreover, gene expression profiles in thoracic aortic aneurysm fibroblasts were different than normal fibroblasts after equivalent biological stimuli. Conclusions: This study demonstrated for the first time that isolated primary aortic fibroblasts from thoracic aortic aneurysm-induced mice possess a unique and stable gene expression profile, and when challenged with biological stimuli, induce a transcriptional response that is different from normal aortic fibroblasts. Together, these data suggest that aortic fibroblasts undergo a stable phenotypic change during thoracic aortic aneurysm development, which may drive the enhancement of extracellular matrix proteolysis in thoracic aortic aneurysm progression.

Epidemiology. and End Results database between 1973 and 2005 Methods: Of the 1987 patients identified. 1334 were analyzed Patients were categorized according to the Masaoka staging system as stage I to IIA, III or IV to IV The primary end points were overall survival, cardiac mortality, and the development of secondary malignancies Results: Patients received surgery and radiation (50%), surgery alone (26%). radiation alone (12%), or no treatment (12%) The median follow-up time for survivors was 65 months (range, 1-361 months) There was no significant increase in the 12-year cumulative incidence rate of death from heart disease (10 2% radiation versus 7 5% no radiation, p = 0 83) or incidence of secondary malignancies (11 7% versus 12 4%, p = 0 70) with radiation Compared with surgery alone, adjuvant radiation significantly improved overall survival in patients with stage III to IV disease (p = 0 04) and demonstrated a nonsignificant trend in patients with stage IIIB disease (p = 0 09) However, after excluding patients surviving less than 4 months to account for surgical mortality, the benefit with radiation was no longer significant (stage IIIB p = 045. stage III-IV p = 0 44) Conclusions: Radiation does not seem to increase the risk of cardiac mortality or secondary malignancy in patients with malignant thymoma Although the routine use of postoperative radiotherapy in malignant thymoma does not appear warranted, high-risk patients may benefit from adjuvant radiation This study can help to design prospective trials to further establish the role of radiotherapy in malignant thymoma C1 [Fernandes, Annemarie T.; Shinohara, Eric T.; Mitra, Nandita; Rengan, Ramesh; Metz, James M.] Univ Penn, Philadelphia, PA 19104 USA.

The objective of this study was to assess the longitudinal Se status of pediatric patients with burns. Methods: Twenty patients admitted to our hospital with burns exceeding 10% of their total body surface area were studied longitudinally during the first 8 weeks of admission or until 95% wound closure was achieved. Dietary Se intake was calculated daily, and plasma and urine samples were collected weekly for analyses of plasma Se, urinary Se, and glutathione peroxidase activity. Results: Patients included in this study were individuals with an average age of 6.5 years +/- 5.3 years and with burn injury of a mean total body surface area of 42% +/- 21%. Dietary Se intake throughout the study (mean = 60 mu g/d +/- 39 mu g/d) was consistent with established standards for healthy children and did not change throughout the study. Plasma Se (mean = 1.08 mu mol/L +/- 0.34 mu mol/L) and plasma glutathione peroxidase (mean = 3.2 U/g protein +/- 1.42 U/g protein) were below reported normal values for healthy American children. Mean urinary Se excretion (65.9 mu g/L +/- 50 mu g/L) exceed dietary Se intake. Plasma Se was inversely related to incidence of total infection (p = 0.04). Conclusions: Results from this study indicate that Se status is depressed among pediatric patients with burns and that recommended Se intake for healthy children is likely insufficient for this population. Further studies are necessary to elucidate the amount of dietary Se required to maximize Se stores among pediatric patients with burn injuries.

We used prepulse inhibition as an operational measure of sensorimotor gating to examine early pre-attentive stages of information processing in females with interstitial cystitis/painful bladder syndrome and healthy controls. Materials and Methods: We assessed prepulse inhibition in 14 female patients with interstitial cystitis/painful bladder syndrome and 17 healthy controls at 60 and 120-millisecond prepulse-to-startle stimulus intervals. We evaluated group differences in prepulse inhibition, and relationships between prepulse inhibition, neuroticism and acute stress ratings. Results: Patients showed significantly decreased prepulse inhibition at 60 and 120-millisecond prepulse intervals. The prepulse inhibition deficit was related to acute stress ratings in the patients. However, increased neuroticism appeared to mitigate the prepulse inhibition deficit in those with interstitial cystitis/painful bladder syndrome, possibly reflecting greater vigilance. Conclusions: Compared to healthy controls, female patients with interstitial cystitis/painful bladder syndrome had decreased ability to adequately filter incoming information and perform appropriate sensorimotor gating. These results suggest that a possible mechanism for altered interoceptive information processing in interstitial cystitis/painful bladder syndrome cases may be a general deficit in filtering mechanisms due to altered pre-attentive processing.

TI Medical therapy of diabetic foot infections SO JOURNAL OF VASCULAR SURGERY LA English DT Article ID STAPHYLOCOCCUS-AUREUS; CLASSIFICATION-SYSTEM; VALIDATION; DIAGNOSIS; RISK AB Diabetic foot infections are a common and often serious problem, accounting for a greater number of hospital bed days than any other complication of diabetes. Despite advances in both antibiotic therapy and surgical management, these infections continue to be a major risk factor for amputations of the lower extremity. Although a number of wound size and depth classification systems have been adapted for use in codifying diabetic foot ulcerations, none are specific for infection. In 2003, the International Working Group on the Diabetic Foot developed guidelines for managing diabetic foot infections, including the first severity scale specific for these infections. The following year, the Infectious Diseases Society of America (IDSA) published their Diabetic Foot Infection Guidelines. In this article, we review some of the critical points from the Executive Summary of the IDSA document and provide a commentary following each issue to update the reader on any pertinent changes that have occurred since the publication of the original document in 2004. The importance of a multidisciplinary limb salvage team, apropos this special joint issue of the American Podiatric Medical Association and the Society for Vascular Surgery, cannot be overstated.

The gp160 envelope glycoprotein precursor undergoes proteolytic cleavage in the Golgi complex to produce the gp120 exterior glycoprotein and the gp41 transmembrane glycoprotein, which remain associated non-covalently in the trimeric Env complex. Monomeric soluble gp120 has been used extensively to investigate conformational states, structure, antigenicity and immunogenicity of the HIV-1 Env glycoproteins. Expression of gp120 alone (without gp41) leads to the accumulation not only of monomeric gp120 but also an aberrant dimeric form. The gp120 dimers were sensitive to reducing agents. The formation of gp120 dimers was disrupted by a single amino acid change in the inner domain, and was reduced by removal of the V1/V2 variable loops or the N and C termini. Epitopes on the gp120 inner domain and the chemokine receptor-binding surface were altered or occluded by gp120 dimerization. Awareness of the existence and properties of gp120 dimers should assist interpretation of studies of this key viral protein. (C) 2010 Elsevier B.V. All rights reserved.

Interestingly, in naive animals, alpha 4 beta 7 expression was associated with increased NK cell activation and, on CD16(+) NK cells, delineated a unique dual-function cytotoxic-CD107a(+)/gamma interferon (IFN-gamma)-secreting population. However, while SIV infection increased CD107a expression on stimulated CD56(+) NK cells, alpha 4 beta 7(+) and alpha 4 beta 7(-) NK cells were affected similarly. These findings suggest that SIV infection redirects NK cells away from the lymph nodes to the gut mucosae but alters NK cell function independent of trafficking repertoires. C1 [Reeves, R.

We determined the association of AKI with risk for heart failure, cardiovascular events, end-stage renal disease (ESRD), and mortality beginning 90 days after discharge. Based on AKI Network criteria, 2453 had stage 1; 273 had stage 2 or 3; and 334 had dialysis-requiring AKI. Over a mean follow-up period of 5.7 years, 333 had heart failure, 673 had cardiovascular diseases (CVDs), 348 developed ESRD, and 8405 deaths occurred. In multivariable-adjusted analyses, AKI stage 1 was associated with death and ESRD, but not heart failure or other CVD. Dialysis-requiring AKI had much stronger and significant associations with increased risk for long-term ESRD, and death in addition to heart failure and cardiovascular events. When AKI was reclassified to account for recovery, stage 1 with recovery was still associated with death, but not ESRD. Thus, in this national sample of HIV-infected persons, we found the clinical repercussions of AKI appear to extend beyond the hospital setting contributing to excess cardiovascular risks, ESRD, and mortality. Additionally, AKI affected almost one of six patients with HIV who survived at least 90 days following discharge.

Until recently, the significance of these other alterations has not been thoroughly investigated. We report the first study that integrates gene expression profiling and high-resolution genomic copy number analyses in GIST. Fresh tissue specimens from 25 patients with GIST were collected, and gene expression profiling and high-resolution genomic copy number analyses were performed, using Affymetrix U133Plus and SNP array 6.0. We found that all 21 mutant GIST patients showed both macroscopic cytogenetic alterations and cryptic microdeletions or amplifications, whereas 75% (three of four) of wild-type patients with GIST did not show genomic imbalances. The most frequently observed chromosomal alterations in patients with mutant GIST included 14q complete or partial deletion (17 of 25), 1p deletion (14 of 25) and 22q deletion (10 of 25). Genetic targets of the chromosomal aberrations were selected by integrated analysis of copy number and gene expression data. We detected the involvement of known oncogenes and tumor suppressors including KRAS in chr 12p amplification and KIF1B, PPM1A, NF2 in chr 1p, 14q and 22p deletions, respectively. The genomic segment most frequently altered in mutated samples was the 14q23.1 region, which contains potentially novel tumor suppressors, including DAAM1, RTN1 and DACT1. siRNA-mediated RTN1 downregulation showed evidence for the potential role in GIST pathogenesis. The combination of gene expression profiling and high-resolution genomic copy number analysis offers a detailed molecular portrait of GISTs, providing an essential comprehensive knowledge necessary to guide the discovery of novel target genes involved in tumor development and progression.

The molecular etiology and pathology of this disease remain unclear, hampering the development of an effective therapy, and there remains a need for more, and more realistic, animal models. HS cells typically show a histiocytic (ie, tissue macrophage-like) morphology and express histiocyte/macrophage markers in the absence of lymphocyte markers. In this study, we report that Dok-1(-/-) Dok-2(-/-) Dok-3(-/-) mice develop HS, but do not exhibit elevated incidence of other types of tumors. These mutant mice showed earlier mortality than wild-type (WT) or the other mutant mice, and this mortality was associated with HS. In total, 17 of 21 tumor-bearing Dok-1(-/-) Dok-2(-/-) Dok-3(-/-) mice necropsied at 25-66 weeks of age showed multiple organ spread, with osteolytic lesions and orthotopic invasion from the bone marrow to skeletal muscle. Tumors from the mice were transplantable. In addition, all Dok-1(-/-) Dok-2(-/-) Dok-3(-/-) mice, but only a small proportion of Dok-3(-/-) mice and no Dok-1(-/-) Dok-2(-/-) mice, exhibited abnormal accumulation of macrophages in the lung on necropsy at 8-12 weeks of age. Macrophages derived from Dok-1(-/-) Dok-2(-/-) Dok-3(-/-) mice displayed an exaggerated proliferative response to macrophage colony-stimulating factor (M-CSF) or granulocyte-macrophage colony-stimulating factor (GM-CSF) compared with WT and mutant controls. Together, these findings indicate that Dok-1, Dok-2, and Dok-3 cooperatively suppress aggressive HS, and commend Dok-1(-/-) Dok-2(-/-) Dok-3(-/-) mice as a useful model for the study of this neoplasia.

TI Second-line systemic therapy and emerging drugs for metastatic transitional-cell carcinoma of the urothelium SO LANCET ONCOLOGY LA English DT Review ID PHASE-II TRIAL; GROWTH-FACTOR RECEPTOR; COOPERATIVE-ONCOLOGY-GROUP; ADVANCED BLADDER-CANCER; PLATINUM-CONTAINING REGIMEN; PROGNOSTIC-FACTORS; M-VAC; NEOADJUVANT CHEMOTHERAPY; KINASE INHIBITOR; TRACT CARCINOMA AB Front-line platinum-based combination chemotherapy leads to high response rates but suboptimum overall survival for patients with advanced transitional-cell carcinoma of the urothelium. Bevacizumab is being assessed in combination with platinum-based first-line chemotherapy in a large phase 3 trial. Current second-line systemic therapies, including taxanes, yield disappointing outcomes. Vinflunine, a novel vinca alkaloid, showed some activity and was recently approved in Europe based on results of the first completed phase 3 trial in the second-line setting. Better understanding of molecular biology and the emergence of novel biological agents now offer the possibility of improved outcomes. Neoadjuvant therapy before cystectomy and consolidation therapy with biological agents after first-line therapy provide a framework for the development of new drugs. We propose that trials to approve new drugs target two separate populations; multicentre non-randomised phase 2 trials should include patients with chemotherapy-resistant disease progressing within 6 months of first-line therapy, and randomised trials might be appropriate for chemotherapy-sensitive disease progressing more than 6 months after first-line therapy. A multidisciplinary approach is necessary to make therapeutic advances. This review discusses current second-line therapy and emerging drugs for advanced transitional-cell carcinoma.

TI A Prospective Study of Cardiovascular Risk Factors and Incident Hearing Loss in Men SO LARYNGOSCOPE LA English DT Article; Proceedings Paper CT Conference on Triological-Society/Combined Otolaryngology Spring Meeting CY APR 28-MAY 02, 2010 CL Las Vegas, NV SP Triol Soc DE Hearing loss; cardiovascular; smoking; cholesterol ID NUTRITION EXAMINATION SURVEY; HEALTH-PROFESSIONALS; DIABETES-MELLITUS; PHYSICAL-ACTIVITY; NATIONAL-HEALTH; UNITED-STATES; OLDER-ADULTS; IMPAIRMENT; PREVALENCE; DISEASE AB Objectives/Hypothesis: Hearing loss is the most common sensory disorder in the United States, affecting more than 36 million people. Cardiovascular risk factors have been associated with the risk of hearing loss in cross-sectional studies, but prospective data are currently lacking. Study Design: Prospective cohort study. Methods: We prospectively evaluated the association between diagnosis of hypertension, diabetes mellitus, hypercholesterolemia, smoking, or body mass index (BMI) and incident hearing loss. Participants were 26,917 men in the Health Professionals Follow-up Study, aged 40 to 74 years at baseline in 1986. Study participants completed questionnaires about lifestyle and medical history every 2 years. Information on self-reported professionally diagnosed hearing loss and year of diagnosis was obtained from the 2004 questionnaire, and cases were defined as hearing loss diagnosed between 1986 and 2004. Multivariable-adjusted hazard ratios (HRs) were calculated using Cox proportional hazards regression models. Results: A total of 3,488 cases of hearing loss were identified. History of hypertension (HR 0.96; 95% confidence interval [CI], 0.88-1.03), diabetes mellitus (HR 0.92; 95% CI, 0.78-1.08), or obesity (HR 1.02; 95% CI, 0.90-1.15 for BMI >= 30 compared to normal range of 19-24.9) was not significantly associated with hearing-loss risk. Hypercholesterolemia (HR -1.10; 95% CI, 1.02-1.18) and past smoking history (HR 1.09; 95% CI, 1.01-1.17) were associated with a significantly increased risk of hearing loss after multivariate adjustment. Conclusions: A history of hypertension, diabetes mellitus, or obesity is not associated with increased risk of hearing loss; a history of past smoking or hypercholesterolemia has a small but statistically significant association with increased risk of hearing loss in adult males.

Rox TI Safety and Effectiveness of Black Tattoo Clearance in a Pig Model After a Single Treatment With a Novel 758 nm 500 Picosecond Laser: A Pilot Study SO LASERS IN SURGERY AND MEDICINE LA English DT Article DE tattoo; removal; laser; nanosecond; picosecond; pigment; porcine; carbon; iron oxide ID PLASMA; PIGMENTS; REMOVAL; PULSES AB Background: Optimal selective photothermolysis of a pigment particle requires pulse durations equal to or less than the particle's thermal relaxation time (t(1/2)). Since tattoo particles in skin range in diameter from 40 to 300 nm, picosecond pulses would approximate t(1/2) more closely and, therefore, might be more effective at tattoo particle fragmentation. Materials and Methods: India Ink (carbon) or iron oxide tattoos were placed on the back of a Yorkshire pig. Six weeks later, each tattoo was treated with either a 758 nm 500 picosecond laser (Cynosure), a 755 nm 30-50 nanoseconds laser, or left untreated. After 4 weeks, clinical responses were evaluated by three dermatologists based on pre- and post-treatment photographs; histopathologic findings were evaluated by a dermatopathologist; and electron microscopic findings were analyzed for treated and non-treated carbon tattoos. Results: After a single treatment, picosecond-domain pulses at 758 nm produced a significantly greater degree of carbon tattoo clearance compared to nanosecond-domain pulses at 755 nm. For iron oxide tattoos, both modalities produced minimal-to-poor clearance that was generally comparable. Neither modality resulted in scarring, textural changes, or hypopigmentation, and there was no histopathologic evidence of scarring. Electron micrographs revealed the presence of amorphous material (treated pigment) in picosecond and nanosecond laser-treated tattoos, consistent with effective targeting of India Ink pigment. Conclusions: The 758 nm 500 picosecond laser is more effective at carbon tattoo clearance after one session in a porcine model than the 30-50 nanosecond laser emitting at a similar wavelength. Both lasers cleared carbon tattoos more effectively than iron oxide tattoos. Both lasers have a comparable safety profile, and neither produced clinical or histopathologic scarring. Further studies in humans are necessary to evaluate whether repeated treatments with picosecond versus nanosecond domain modalities might yield superior tattoo pigment clearance with a comparable safety profile.

TI Defining menopausal status in epidemiologic studies: A comparison of multiple approaches and their effects on breast cancer rates SO MATURITAS LA English DT Article DE Menopause; Breast cancer; Incidence; Concordance ID MENSTRUAL FACTORS; RISK; TRANSITION; WOMEN AB Objectives: Menopausal status is a common covariate in epidemiologic studies. Still, there are no standard definitions for menopausal status using observational data. This study assesses distinctions between menopausal status definitions using commonly collected epidemiologic data, and explores their impact on study outcomes using breast cancer rates as an example. Study design: Using survey data from 227,700 women aged 40-64 who received screening mammograms from the Breast Cancer Surveillance Consortium, we classified menopausal status under five different definitions: one complex definition combining multiple variables, two definitions using age as a proxy for menopausal status, one based only on menstrual period status, and one based on age and menstrual period status. Main outcome measures: We compared the distribution of menopausal status and menopausal status-specific breast cancer incidence and detection rates across definitions for menopausal status. Results: Overall, 36% and 29% of women were consistently classified as postmenopausal and premenopausal, respectively, across all definitions. Menopausal status-specific breast cancer incidence and detection rates were similar across definitions. Rates were unchanged when information regarding natural menopause, bilateral oophorectomy, hormone therapy, and timing of last menstrual period were sequentially added to definitions of postmenopausal status. Conclusions: Distinctions in menopausal status definitions contribute to notable differences in how women are classified, but translate to only slight differences in menopausal status-specific breast cancer rates.

TI Provision of Potentially Teratogenic Medications to Female Veterans of Childbearing Age SO MEDICAL CARE LA English DT Article DE women; preconception counseling; medication safety; contraception ID UNITED-STATES; BIRTH-DEFECTS; CARE; PREGNANCY; HEALTH; WOMEN; PRECONCEPTION; PRESCRIPTION AB Background: Certain medications increase the risk of birth defects whether used during pregnancy or immediately preconception. Objectives: To describe dispensing of potentially teratogenic medications (Food and Drug Administration classes D or X) to female Veterans treated by the Veterans Affairs (VA) Healthcare System, and assess whether documented provision of family planning services is more common when potentially teratogenic medications are prescribed. Research Design: We examined all 2,634,441 prescriptions filled in fiscal year 2007 or 2008 by 78,232 female Veterans, aged 18 to 45, who made >= 2 visits to VA clinics within the year prior to medication dispensing from VA pharmacies. Measures: Medications dispensed, contraceptive counseling, and pregnancy testing. Results: Prescriptions for potentially teratogenic medications were filled by 48.8% of female Veterans who received medications from a VA pharmacy. Women who filled prescriptions for potentially teratogenic medications were only slightly more likely to have documented family planning services (eg, contraception, contraceptive counseling, or pregnancy testing) than women who filled class C, but not class D or X, prescriptions (55.7% vs. 51.8%). Women filling only class A or B prescriptions were least likely to have documented family planning services (35.9%). Among women dispensed potentially teratogenic medications, family planning services were significantly more likely to be documented for women who were >= 25 years (odds ratio [OR], 2.82; 95% confidence interval [CI], 2.57-3.11), unmarried (OR, 1.30; 95% CI, 1.23-1.35), non-White (OR, 1.17; 95% CI, 1.09-1.26), seen at a women's clinic (OR, 1.96; 95% CI, 1.88-2.05), received a retinoid medication (OR, 7.72; 95% CI, 3.02- 19.7), or had serious mental illness (OR, 1.26; 95% CI, 1.18-1.34). Conclusions: Medications that may cause birth defects if used during pregnancy are dispensed frequently to female Veterans by VA pharmacies without documented receipt of contraceptive counseling or pregnancy testing.

TI Patients' Knowledge about 9 Common Health Conditions: The DECISIONS Survey SO MEDICAL DECISION MAKING LA English DT Article DE informed decision making; patient education; knowledge ID LUMBAR SPINAL STENOSIS; LOW-BACK-PAIN; RANDOMIZED CONTROLLED-TRIAL; INFORMED DECISION; NONOPERATIVE TREATMENT; CATARACT-SURGERY; DISK HERNIATION; SCREENING MAMMOGRAPHY; PRIMARY PREVENTION; AMERICAN-COLLEGE AB Background. To make informed decisions, patients must have adequate knowledge of key decision-relevant facts. Objective. To determine adults' knowledge about information relevant to common types of medication, screening, or surgery decisions they recently made. Setting. National sample of US adults identified by random-digit dialing. Design. Cross-sectional survey conducted between November 2006 and May 2007. Participants. A total of 2575 English-speaking adults aged 40 y or older who reported having discussed the following medical decisions with a health care provider within the previous 2 y: prescription medications for hypertension, hypercholesterolemia, or depression; screening tests for colorectal, breast, or prostate cancer; or surgeries for knee/hip replacement, cataracts, or lower back pain. Measurements. Participants answered knowledge questions and rated the importance of their health care provider, family/friends, and the media as sources of information. Results. Accuracy rates varied widely across questions and decision contexts. For example, patients considering cataract surgery were more likely to correctly estimate recovery time than those patients considering lower back pain or knee/hip replacement (78% v. 29% and 39%, P < 0.001). Similarly, participants were more knowledgeable of facts about colorectal cancer screening than those who were asked about breast or prostate cancer. Finally, respondents were consistently more knowledgeable on comparable questions about blood pressure medication than cholesterol medication or antidepressants. The impact of demographic characteristics and sources of information also varied substantially. For example, blacks had lower knowledge than whites about cancer screening decisions (odds ratio [OR] = 0.57; 95% confidence interval [CI] = 0.43, 0.75; P = 0.001) and medication (OR = 0.77; 95% CI = 0.60, 0.97; P = 0.03) even after we controlled for other demographic factors. The same was not true for surgical decisions. Limitations. The questions did not measure all knowledge relevant to informed decision making, were subject to recall biases, and may have assessed numeracy more than knowledge. Conclusions. Patient knowledge of key facts relevant to recently made medical decisions is often poor and varies systematically by decision type and patient characteristics. Improving patient knowledge about risks, benefits, and characteristics of medical procedures is essential to support informed decision making.

Patients should understand the risks and benefits of cancer screening in order to make informed screening decisions. Objectives. To evaluate the extent of informed decision making in patient-provider discussions for colorectal (CRC), breast (BrCa), and prostate (PCa) cancer screening. Setting. National sample of US adults identified by random-digit dialing. Design. Cross-sectional survey conducted between November 2006 and May 2007. Participants. English-speaking US adults aged 50 y and older who had discussed cancer screening with a health care provider within the previous 2 y. Measurements. Cancer screening survey modules that asked about demographic characteristics, cancer knowledge, the importance of various sources of information, and self-reported cancer screening decision-making processes. Results. Overall, 1082 participants completed 1 or more of the 3 cancer modules. Although participants generally considered themselves well informed about screening tests, half or more could not correctly answer even 1 open-ended knowledge question for any given module. Participants consistently overestimated risks for being diagnosed with and dying from each cancer and overestimated the positive predictive values of prostate-specific antigen tests and mammography. Providers were the most highly rated information source, usually initiated screening discussions (64%-84%), and often recommended screening (73%-90%). However, participants reported that providers elicited their screening preferences in only 31% (CRC women) to 57% (PCa) of discussions. Although more than 90% of the discussions addressed the pros of screening, only 19% (BrCa) to 30% (PCa) addressed the cons of screening. Limitations. Recall bias is possible because screening process reports were not independently validated. Conclusions. Cancer screening decisions reported by patients who discussed screening with their health care providers consistently failed to meet criteria for being informed. Given the high ratings for provider information and frequent recommendations for screening, providers have important opportunities to ensure that informed decision making occurs for cancer screening decisions.

The DECISIONS Survey SO MEDICAL DECISION MAKING LA English DT Article DE shared decision making; provider decision making; patient decision making; decision aids; decision analysis; performance measures; pay-for-performance; physician-patient communication ID KNOWLEDGE; PROGRAM AB Background. An important part of delivering high-quality, patient-centered care is making sure patients are informed about decisions regarding their health care. The objective was to examine whether patients' perceptions about how informed they were about common medical decisions are related to their ability to answer various knowledge questions. Methods. A cross-sectional survey was conducted November 2006 to May 2007 of a national sample of US adults identified by random-digit dialing. Participants were 2575 English-speaking US adults aged 40 and older who had made 1 of 9 medication, cancer screening, or elective surgery decisions within the previous 2 years. Participants rated how informed they felt on a scale of 0 (not at all informed) to 10 (extremely well-informed), answered decision-specific knowledge questions, and completed standard demographic questions. Results. Overall, 36% felt extremely well informed (10), 30% felt well informed (8-9), and 33% felt not at all to somewhat informed (0-7). Multivariate logistic regression analyses showed no overall relationship between knowledge scores and perceptions of being extremely well informed (odds ratio [OR] = 0.94, 95% confidence interval [CI] 0.63-1.42, P = 0.78). Three patterns emerged for decision types: a negative relationship for cancer screening decisions (OR = 0.58, CI 0.33-1.02, P = 0.06), no relationship for medication decisions (OR = 0.99, CI 0.54-1.83, P = 0.98), and a positive relationship for surgery decisions (OR = 3.07, 95% CI 0.90-10.54, P = 0.07). Trust in the doctor was associated with feeling extremely well-informed for all 3 types of decisions. Lower education and lower income were also associated with feeling extremely well informed for medication and screening decisions. Retrospective survey data are subject to recall bias, and participants may have had different perspectives or more factual knowledge closer to the time of the decision. Conclusions. Patients facing common medical decisions are not able to accurately assess how well informed they are. Clinicians need to be proactive in providing adequate information to patients and testing patients' understanding to ensure informed decisions.

Harry TI Estimation of pulse transit time using two diametric blood pressure waveform measurements SO MEDICAL ENGINEERING & PHYSICS LA English DT Article DE Pulse transit time; Blind system identification; Blood pressure; Cardiovascular system ID ARTERIAL STIFFNESS; VELOCITY; MODEL; ECG AB This paper presents a novel method to estimate the aortic-to-peripheral pulse transit time (PTT) using the blood pressure waveforms measured at two diametric peripheral locations, for instance, one on an upper extremity and the other on a lower extremity. The method is based on a computational relationship between the two peripheral blood pressures, which is derived by first relating each peripheral blood pressure to a common central aortic blood pressure. The parameters of the computational relationship for an individual subject can be identified by fitting them to two peripheral blood pressure waveform measurements, thereby characterizing the cardiovascular dynamics, from which absolute changes in the PTT between the central aorta and each peripheral measurement site can be determined. The strength of the method is that it does not require any a priori knowledge of the peripheral measurement locations nor of the physiologic condition of the cardiovascular system. Experimental results are provided from five healthy swine subjects whose actual PTT experimentally varied from 44.9 ms to 163.0 ms (76.7 ms mean +/- 26.4 ms SD). Compared to the reference PTT measurement, the novel method proposed in this paper estimated PTT within 3.7 ms mean +/- 4.2 ms SD after initial calibration. (C) 2010 IPEM. Published by Elsevier Ltd.

In a prospective cohort comprising 146 SOT recipients with cryptococcosis, we describe the presentation, antifungal therapy, and outcome of cutaneous cryptococcal disease. Cutaneous cryptococcosis was documented in 26/146 (17.8%) of the patients and manifested as nodular/mass (34.8%), maculopapule (30.4%), ulcer/pustule/abscess (30.4%), and cellulitis (30.4%) with 65.2% of the skin lesions occurred in the lower extremities. Localized disease developed in 30.8% (8/26), and disseminated disease in 69.2% (18/26) with involvement of the central nervous system (88.9%, 16/18), lung (33.3%, 6/18), or fungemia (55.6%, 10/18). Fluconazole (37.5%) was employed most often for localized and lipid formulations of amphotericin B (61.1%) for disseminated disease. Overall mortality at 90 days was 15.4% (4/26) with 16.7% in disseminated and 12.5% in localized disease (P = 0.78). SOT recipients who died were more likely to have renal failure (75.0% vs. 13.6%, P = 0.028), longer time to onset of disease after transplantation (87.5 vs. 22.6 months, P = 0.023), and abnormal mental status (75% vs. 13.6%, P = 0.028) than those who survived. Cutaneous cryptococcosis represents disseminated disease in most SOT recipients and preferentially involves the extremities. Outcomes with appropriate management were comparable between SOT recipients with localized and disseminated cryptococcosis.

TI Screening for drug-resistant Candida yeasts with chromogenic agar SO MEDICAL MYCOLOGY LA English DT Article DE Candida; resistance; echinocandin; azole ID PATIENTS RECEIVING RADIATION; DISK DIFFUSION METHODS; IN-VITRO ACTIVITIES; ANTIFUNGAL SUSCEPTIBILITY; ORAL COLONIZATION; SEPSIS SECONDARY; AMPHOTERICIN-B; NECK-CANCER; CASPOFUNGIN; GLABRATA AB We examined the utility of agar dilution to screen yeasts for reduced susceptibility to several newer antifungal drugs including echinocandins and azoles. We compared agar dilution susceptibility screening with the Clinical and Laboratory Standards Institute (CLSI) method for Candida isolates. We added echinocandins and azoles to CHROMagar Candida medium prior to its solidification. Assessment of resistance was based on growth characteristics, wherein decreased colony size in the presence of antifungal drugs was used as an indicator of susceptibility. Clinical Candida isolates of C. albicans, C. glabrata, C. parapsilosis, C. tropicalis, C. guilliermondii, C. lusitaniae, C. rugosa and C. dubliniensis were screened for drug susceptibility. Overall, antifungal susceptibility of the yeasts to anidulafungin, caspofungin, micafungin, posaconazole and voriconazole, determined using CHROMagar agar dilution, were shown to be 96, 80, 94, 90 and 97% as accurate, respectively, as those determined by the CLSI method, i.e., within one tube dilution of CLSI MICs. Categorical errors by percentage had a broader range. Major errors noted with anidulafungin, caspofungin and micafungin were 3, 6 and 0%, respectively, while very major errors were 15, 55 and 38%, respectively. Major errors with posaconazole and voriconazole were 12 and 0%, respectively, while very major errors were 0 and 22%, respectively, compared to CLSI standards. Most of the assessment errors were found with C. glabrata and C. parapsilosis. Agar dilution screening for drug susceptibility with the current panel of antifungal drugs is rapid, accurate and effective. However, the determination of resistance or non-susceptibility in yeasts may be more problematic, and may be species dependent.

TI A fast optimization algorithm for multicriteria intensity modulated proton therapy planning SO MEDICAL PHYSICS LA English DT Article DE projection method; multi-criteria; optimization; numerical evaluation ID FLUENCE MAP OPTIMIZATION; RADIATION-THERAPY; ITERATIVE ALGORITHMS; FEASIBILITY PROBLEM; RADIOTHERAPY; IMRT; CONSTRAINTS; PROJECTIONS; MODELS AB Purpose: To describe a fast projection algorithm for optimizing intensity modulated proton therapy (IMPT) plans and to describe and demonstrate the use of this algorithm in multicriteria IMPT planning. Methods: The authors develop a projection-based solver for a class of convex optimization problems and apply it to IMPT treatment planning. The speed of the solver permits its use in multicriteria optimization, where several optimizations are performed which span the space of possible treatment plans. The authors describe a plan database generation procedure which is customized to the requirements of the solver. The optimality precision of the solver can be specified by the user. Results: The authors apply the algorithm to three clinical cases: A pancreas case, an esophagus case, and a tumor along the rib cage case. Detailed analysis of the pancreas case shows that the algorithm is orders of magnitude faster than industry-standard general purpose algorithms (MOSEK's interior point optimizer, primal simplex optimizer, and dual simplex optimizer). Additionally, the projection solver has almost no memory overhead. Conclusions: The speed and guaranteed accuracy of the algorithm make it suitable for use in multicriteria treatment planning, which requires the computation of several diverse treatment plans. Additionally, given the low memory overhead of the algorithm, the method can be extended to include multiple geometric instances and proton range possibilities, for robust optimization.

Serotonin-norepinephrine reuptake inhibitors (SNRIs) and selective serotonin reuptake inhibitors (SSRIs) are used widely but are only partially effective for hot flashes. Alternative strategies are needed. We hypothesized that augmentation of SSRI/SNRI therapy with hypnotic agents would optimize hot flash therapy by improving sleep and quality of life. Methods: Women with breast cancer or at high risk for developing the disease who had hot flashes in association with nocturnal awakenings were randomized to double-blinded treatment with zolpidem 10 mg or placebo for 5 weeks. SSRI/SNRI nonusers (81%) started venlafaxine XR 75 mg/day concurrently, whereas SSRI/SNRI users continued that therapy. We compared the proportion of responders, defined as study completers with improved subjective sleep quality (Pittsburgh Sleep Quality Index) and/or objectively assessed wake time after sleep onset on actigraphy, between groups. Results: Of 53 women (aged 51 +/- 8 y) randomized to zolpidem augmentation (n = 25) or placebo augmentation (n = 28), 38 completed the protocol (57% on placebo, 88% on zolpidem). More women augmented with zolpidem than placebo were responders on the sleep outcome (40% vs 14%; P = 0.035). Quality of life improved more with zolpidem than with placebo (P = 0.01). Treatment effects on hot flashes and mood did not differ between groups. Conclusions: Augmentation of SSRI/SNRI with zolpidem improves sleep and quality of life in breast cancer survivors with hot flashes and associated sleep disturbance. Adding a hypnotic agent to an SSRI/SNRI helps women to sleep through nighttime hot flashes. Treatments targeting sleep may be an important supplemental strategy to optimize well-being.

Since mammalian systems perform various functions, a multiobjective approach is needed when seeking optimal flux distributions in these systems. In most of the available multiobjective optimization methods, there is a lack of understanding of when to use a particular objective, and how to combine and/or prioritize mutually competing objectives to achieve a truly optimal solution. To address these limitations we developed a soft constraints based linear physical programming-based flux balance analysis (LPPFBA) framework to obtain a multiobjective optimal solutions. The developed framework was first applied to compute a set of multiobjective optimal solutions for various pairs of objectives relevant to hepatocyte function (urea secretion, albumin, NADPH, and glutathione syntheses) in bioartificial liver systems. Next, simultaneous analysis of the optimal solutions for three objectives was carried out. Further, this framework was utilized to obtain true optimal conditions to improve the hepatic functions in a simulated bioartificial liver system. The combined quantitative and visualization framework of LPPFBA is applicable to any large-scale metabolic network system, including those derived by genomic analyses. (C) 2010 Elsevier Inc.

SO MILBANK QUARTERLY LA English DT Article DE Internship; residency; duty-hour regulations; professionalism ID HOURS REFORM; RESIDENTS; REGULATIONS; MORTALITY; RESTRICTIONS; ATTITUDES; EDUCATION; MEDICINE; SURGEONS; LIMITS AB Methods: In 2008, we conducted three months of ethnographic observation of internal medicine and general surgery residents as they went about their everyday work in two hospitals affiliated with the same training program, as well as in-depth interviews with seventeen residents. Field notes and interview transcripts were analyzed for perceptions and behaviors in regard to beginning and leaving work, reporting duty hours, and expressing opinions about DHR. Findings: The respondents did not exhibit a "shift work" mentality in relation to their work. We found that residents: (1) occasionally stay in the hospital in order to complete patient care tasks even when, according to the clock, they are required to leave, because the organizational culture stresses performing work thoroughly, (2) do not blindly embrace noncompliance with DHR but are thoughtful about the tradeoffs inherent in the regulations, and (3) express nuanced and complex reasons for erroneously reporting duty hours, suggesting that reporting hours worked is not a simple issue of lying or truth telling. Conclusions: Concerns about DHR and the erosion of resident professionalism resulting from the development of a "shift work" mentality likely have been overstated. Instead, the influence of DHR on professionalism is more complex than the conventional wisdom suggests and requires additional assessment.

Analysis of gene expression in BMP7-treated fibroblasts revealed a coordinated change in insulin signaling components by BMP7. To further investigate the cross talk between insulin and BMP signaling systems in brown adipogenesis, we examined the effect of BMP7 in insulin receptor substrate 1 (IRS-1)-deficient brown preadipocytes, which exhibit a severe defect in differentiation. Treatment of these cells with BMP7 for 3 days prior to adipogenic induction restored differentiation and expression of brown adipogenic markers. The high level of adipogenic inhibitor preadipocyte factor 1 (Pref-1) in IRS-1-null cells was markedly reduced by 3 days of BMP7 treatment, and analysis of the 1.3-kb pref-1 promoter revealed 9 putative Smad binding elements (SBEs), suggesting that BMP7 could directly suppress Pref-1 expression, thereby allowing the initiation of the adipogenic program. Using a series of sequential deletion mutants of the pref-1 promoter linked to the luciferase gene and chromatin immunoprecipitation, we demonstrate that the promoter-proximal SBE (-192/-184) was critical in mediating BMP7's suppressive effect on pref-1 transcription. Together, these data suggest cross talk between the insulin and BMP signaling systems by which BMP7 can rescue brown adipogenesis in cells with insulin resistance.

TI Autophagy Induction with RAD001 Enhances Chemosensitivity and Radiosensitivity through Met Inhibition in Papillary Thyroid Cancer SO MOLECULAR CANCER RESEARCH LA English DT Article ID CELL-DEATH; MAMMALIAN TARGET; LUNG-CANCER; HEPATOCELLULAR-CARCINOMA; ANTITUMOR-ACTIVITY; EVEROLIMUS RAD001; OVARIAN-CANCER; MOUSE MODEL; THERAPY; MTOR AB Although autophagy is generally considered a prosurvival mechanism that preserves viability, there is evidence that it could drive an alternative programmed cell death pathway in cells with defects in apoptosis. Because the inhibition of autophagic activity promotes resistance to both chemotherapy and external beam radiation in papillary thyroid cancer (PTC), we determined if RAD001, a potent activator of autophagy, improves the efficacy of either therapy. We found that RAD001 increased the expression level of light chain 3-II, a marker for autophagy, as well as autophagosome formation in cell lines and in human PTC ex vivo. RAD001 sensitized PTC to doxorubicin and external beam radiation in a synergistic fashion, suggesting that combination therapy could improve therapeutic response at less toxic concentrations. The effects of RAD001 were abrogated by RNAi knockdown of the autophagy-related gene 5, suggesting that RAD001 acts, in part, by enhancing autophagy. Because the synergistic activity of RAD001 with doxorubicin and external radiation suggests distinct and complementary mechanisms of action, we characterized how autophagy modulates signaling pathways in PTC. To do so, we performed kinome profiling and discovered that autophagic activation resulted in Src phosphorylation and Met dephosphorylation. Src inhibition did not reverse the effects of RAD001, whereas Met inhibition reversed the effects of autophagy blockade on chemosensitivity. These results suggest that the anticancer effects of autophagic activation are mediated largely through Met. We conclude that RAD001 induces autophagy, which enhances the therapeutic response to cytotoxic chemotherapy and external beam radiation in PTC. Mol Cancer Res; 8(9); 1217-26. (C)2010 AACR.

TI Discovery and Characterization of Novel Mutant FLT3 Kinase Inhibitors SO MOLECULAR CANCER THERAPEUTICS LA English DT Article ID INTERNAL TANDEM DUPLICATION; ACUTE MYELOID-LEUKEMIA; TYROSINE KINASE; BCR-ABL; ACTIVATING MUTATION; FLT3-EXPRESSING CELLS; QUANTITATIVE-ANALYSIS; THERAPEUTIC TARGET; GENE; RESISTANCE AB For a subpopulation of acute myeloid leukemia (AML) patients, the constitutively activated tyrosine kinase, mutant FLT3, has emerged as a promising target for therapy. The development of drug resistance, however, is a growing concern for mutant FLT3 inhibitors, such as PKC412. Potential therapeutic benefit can arise from the combination of two structurally diverse inhibitors that target-but bind differently to-the same protein or from two inhibitors with completely different mechanisms of action. Thus, there is a need for identification and development of novel FLT3 inhibitors that have the ability to positively combine with PKC412 or standard chemotherapeutic agents used to treat AML as a way to suppress the development of drug resistance and consequently prolong disease remission. Here, we report the effects of the novel type II ATP-competitive inhibitors, HG-7-85-01 and HG-7-86-01, which potently and selectively target mutant FLT3 protein kinase activity and inhibit the proliferation of cells harboring FLT3-ITD or FLT3 kinase domain point mutants via induction of apoptosis and cell cycle inhibition. Antileukemic activity of HG-7-85-01 was shown in vivo to be comparable with that observed with PKC412 in a bioluminescence assay using NCr nude mice harboring Ba/F3-FLT3-ITD-luc+ cells. HG-7-85-01 was also observed to override PKC412 resistance. Finally, HG-7-85-01 and HG-7-86-01 synergized with PKC412 and standard chemotherapeutic agents against mutant PKC412-sensitive and some PKC412-resistant, FLT3-positive cells. Thus, we present a structurally novel class of FLT3 inhibitors that warrants consideration for clinical testing against drug-resistant disease in AML patients. Mol Cancer Ther; 9(9); 2468-77.

TI Altered interactions of tryptophan metabolites in first-episode neuroleptic-naive patients with schizophrenia SO MOLECULAR PSYCHIATRY LA English DT Article DE Trp; N-acetylserotonin; 5-hydroxyindoleacetic acid; schizophrenia; first-episode neuroleptic naive; targeted metabolomics ID PERFORMANCE LIQUID-CHROMATOGRAPHY; PLATELET SEROTONIN CONCENTRATION; ENDOGENOUS KYNURENIC ACID; CEREBROSPINAL-FLUID; LIPID-PEROXIDATION; N-ACETYLSEROTONIN; 5-HYDROXYINDOLEACETIC ACID; METABOLOMIC ANALYSIS; DIETARY TRYPTOPHAN; OXIDATIVE DAMAGE AB Schizophrenia is characterized by complex and dynamically interacting perturbations in multiple neurochemical systems. In the past, evidence for these alterations has been collected piecemeal, limiting our understanding of the interactions among relevant biological systems. Earlier, both hyper- and hyposerotonemia were variously associated with the longitudinal course of schizophrenia, suggesting a disturbance in the central serotonin (5-hydroxytryptamine (5-HT)) function. Using a targeted electrochemistry-based metabolomics platform, we compared metabolic signatures consisting of 13 plasma tryptophan (Trp) metabolites simultaneously between first-episode neuroleptic-naive patients with schizophrenia (FENNS, n = 25) and healthy controls (HC, n = 30). We also compared these metabolites between FENNS at baseline (BL) and 4 weeks (4w) after antipsychotic treatment. N-acetylserotonin was increased in FENNS-BL compared with HC (P = 0.0077, which remained nearly significant after Bonferroni correction). N-acetylserotonin/Trp and melatonin (Mel)/serotonin ratios were higher, and Mel/N-acetylserotonin ratio was lower in FENNS-BL (all P-values < 0.0029), but not after treatment, compared with HC volunteers. All three groups had highly significant correlations between Trp and its metabolites, Mel, kynurenine, 3-hydroxykynurenine and tryptamine. However, in the HC, but in neither of the FENNS groups, serotonin was highly correlated with Trp, Mel, kynurenine or tryptamine, and 5-hydroxyindoleacetic acid (5HIAA) was highly correlated with Trp, Mel, kynurenine or 3-hydroxykynurenine. A significant difference between HC and FENNS-BL was further shown only for the Trp-5HIAA correlation. Thus, some metabolite interactions within the Trp pathway seem to be altered in the FENNS-BL patients. Conversion of serotonin to N-acetylserotonin by serotonin N-acetyltransferase may be upregulated in FENNS patients, possibly related to the observed alteration in Trp-5HIAA correlation. Considering N-acetylserotonin as a potent antioxidant, such increases in N-acetylserotonin might be a compensatory response to increased oxidative stress, implicated in the pathogenesis of schizophrenia.

The International Molecular Genetic Study of Autism Consortium previously identified linkage loci on chromosomes 7 and 2, termed AUTS1 and AUTS5, respectively. In this study, we performed a high-density association analysis in AUTS1 and AUTS5, testing more than 3000 single nucleotide polymorphisms (SNPs) in all known genes in each region, as well as SNPs in non-genic highly conserved sequences. SNP genotype data were also used to investigate copy number variation within these regions. The study sample consisted of 127 and 126 families, showing linkage to the AUTS1 and AUTS5 regions, respectively, and 188 gender-matched controls. Further investigation of the strongest association results was conducted in an independent European family sample containing 390 affected individuals. Association and copy number variant analysis highlighted several genes that warrant further investigation, including IMMP2L and DOCK4 on chromosome 7. Evidence for the involvement of DOCK4 in autism susceptibility was supported by independent replication of association at rs2217262 and the finding of a deletion segregating in a sib-pair family.

Fundamental to the health of the ocular surface is the immune system, designed to respond rapidly to environmental and microbial insults, whereas maintaining tolerance to self-antigens and commensal microbes. To this end, activation of the innate and adaptive immune response is tightly regulated to limit bystander tissue damage. However, aberrant activation of the immune system can result in autoimmunity to self-antigens localized to the ocular surface and associated tissues. Environmental, microbial and endogenous stress, antigen localization, and genetic factors provide the triggers underlying the immunological events that shape the outcome of the diverse spectrum of autoimmune-based ocular surface disorders.

TI Polyreactivity increases the apparent affinity of anti-HIV antibodies by heteroligation SO NATURE LA English DT Article ID HUMAN-IMMUNODEFICIENCY-VIRUS; HUMAN MONOCLONAL-ANTIBODIES; MEMORY B-CELLS; NEUTRALIZING ANTIBODIES; ENVELOPE GLYCOPROTEIN; TYPE-1; AUTOREACTIVITY; INDIVIDUALS; MODULATION; GENERATION AB During immune responses, antibodies are selected for their ability to bind to foreign antigens with high affinity, in part by their ability to undergo homotypic bivalent binding. However, this type of binding is not always possible. For example, the small number of gp140 glycoprotein spikes displayed on the surface of the human immunodeficiency virus (HIV) disfavours homotypic bivalent antibody binding(1-3). Here we show that during the human antibody response to HIV, somatic mutations that increase antibody affinity also increase breadth and neutralizing potency. Surprisingly, the responding naive and memory B cells produce polyreactive antibodies, which are capable of bivalent heteroligation between one high-affinity anti-HIV-gp140 combining site and a second low-affinity site on another molecular structure on HIV. Although cross-reactivity to self-antigens or polyreactivity is strongly selected against during B-cell development(4), it is a common serologic feature of certain infections in humans, including HIV, Epstein-Barr virus and hepatitis C virus. Seventy-five per cent of the 134 monoclonal anti-HIV-gp140 antibodies cloned from six patients(5) with high titres of neutralizing antibodies are polyreactive. Despite the low affinity of the polyreactive combining site, heteroligation demonstrably increases the apparent affinity of polyreactive antibodies to HIV.

We confirmed associations with SNCA(2,6-8) and MAPT(3,7-9), replicated an association with GAK9 (using data from the NGRC and a previous study(9), P = 3.2 x 10(-9)) and detected a new association with the HLA region (using data from the NGRC only, P = 2.9 x 10(-8)), which replicated in two datasets (meta-analysis P = 1.9 x 10(-10)). The HLA association was uniform across all genetic and environmental risk strata and was strong in sporadic (P = 5.5 x 10(-10)) and late-onset (P = 2.4 x 10(-8)) disease. The association peak we found was at rs3129882, a noncoding variant in HLA-DRA. Two studies have previously suggested that rs3129882 influences expression of HLA-DR and HLA-DQ(10,11). The brains of individuals with Parkinson's disease show upregulation of DR antigens and the presence of DR-positive reactive microglia(12), and nonsteroidal anti-inflammatory drugs reduce Parkinson's disease risk(4,13). The genetic association with HLA supports the involvement of the immune system in Parkinson's disease and offers new targets for drug development.

TI Therapeutic cell engineering with surface-conjugated synthetic nanoparticles SO NATURE MEDICINE LA English DT Article ID T-LYMPHOCYTES; STEM-CELLS; TRANSPLANTATION; ANTIGEN; IMPACT; CANCER; EXPANSION; TARGET; IL-15; TRIAL AB A major limitation of cell therapies is the rapid decline in viability and function of the transplanted cells. Here we describe a strategy to enhance cell therapy via the conjugation of adjuvant drug-loaded nanoparticles to the surfaces of therapeutic cells. With this method of providing sustained pseudoautocrine stimulation to donor cells, we elicited marked enhancements in tumor elimination in a model of adoptive T cell therapy for cancer. We also increased the in vivo repopulation rate of hematopoietic stem cell grafts with very low doses of adjuvant drugs that were ineffective when given systemically. This approach is a simple and generalizable strategy to augment cytoreagents while minimizing the systemic side effects of adjuvant drugs. In addition, these results suggest therapeutic cells are promising vectors for actively targeted drug delivery.

Among existing pO(2) measurement methods, phosphorescence quenching is optimally suited for the task. However, previous attempts to couple phosphorescence with two-photon laser scanning microscopy have faced substantial difficulties because of extremely low two-photon absorption cross-sections of conventional phosphorescent probes. Here we report to our knowledge the first practical in vivo two-photon high-resolution pO(2) measurements in small rodents' cortical microvasculature and tissue, made possible by combining an optimized imaging system with a twophoton-enhanced phosphorescent nanoprobe. The method features a measurement depth of up to 250. m, sub-second temporal resolution and requires low probe concentration. The properties of the probe allowed for direct high-resolution measurement of cortical extravascular (tissue) pO(2), opening many possibilities for functional metabolic brain studies.

Motivated by these properties and by current clinical needs, numerous diagnostic(3-10) and therapeutic(11-13) nanomaterials have recently emerged. Here we describe a novel nanoparticle targeting platform that uses a rapid, catalyst-free cycloaddition as the coupling mechanism. Antibodies against biomarkers of interest were modified with trans-cyclooctene and used as scaffolds to couple tetrazine-modified nanoparticles onto live cells. We show that the technique is fast, chemoselective, adaptable to metal nanomaterials, and scalable for biomedical use. This method also supports amplification of biomarker signals, making it superior to alternative targeting techniques including avidin/biotin.

Patients with diabetes mellitus commonly have multiple comorbidities treated with a wide variety of medications. Systemic medications that target glycemic control and coexisting conditions may have beneficial or deleterious effects on the onset or progression of diabetic retinopathy. In addition, data is accumulating to suggest that the use of systemic therapy primarily to address ocular complications of diabetic retinopathy may be a promising therapeutic approach. This article reviews our current understanding of the ocular-specific effects of systemic medications commonly used by patients with diabetes mellitus, including those directed at control of hyperglycemia, dyslipidemia, hypertension, cardiac disease, anemia, inflammation and cancer. Current clinical evidence is strongest for the use of angiotensin-converting enzyme inhibitors and angiotensin-2 receptor blockers in preventing the onset or slowing the progression of early diabetic retinopathy. To a more limited extent, evidence of a benefit of fibrates for diabetic macular edema exists. Numerous other agents hold considerable promise or potential risk. Thus, these compounds must undergo further rigorous study to determine the actual clinical efficacy and adverse effects before definitive therapeutic care recommendations can be offered.

Dysregulation of these programmes can lead to malignant growth and cancer. This Review focuses on recent advances in our understanding of the transcriptional functions of NFAT proteins in the immune system and provides new insights into their potential roles in cancer development.

R, of a contrasting early-myelinating region (splenium of the corpus callosum) was also measured Results FLwm R(2) and FTS measures were significantly correlated (r=45, p<0001) with no association noted in the early-myelinating region (splenium) Both FLwm R(2) and FTS had significantly quadratic lifespan trajectories that were virtually indistinguishable and both reached a peak at 39 years of age and declined with an accelerating trajectory thereafter Conclusions The results suggest that in this very healthy male sample, maximum motor speed requiring high-frequency AP burst may depend on brain myelin integrity To the extent that the FLwm changes assessed by R(2) contribute to an age-related reduction in AP burst frequency, it is possible that other brain functions dependent on AP bursts may also he affected Non-invasive measures of myelin integrity together with testing of basic measures of processing speed may aid in developing and targeting anti-aging treatments to mitigate age-related functional declines (C) 2008 Elsevier Inc All rights reserved C1 [Bartzokis, George; Richard, Aurore; Peters, Douglas G.; Oluwadara, Bolanle] Univ Calif Los Angeles, David Geffen Sch Med, Dept Psychiat & Biobehav Sci, Los Angeles, CA 90024 USA.

The system must encode the speech motor programs that command movement trajectories of the articulators and monitor transient spatiotemporal variations in auditory and somatosensory feedback. Early models of this system proposed that independent neural regions perform specialized speech processes. As technology advanced, neuroimaging data revealed that the dynamic sensorimotor processes of speech require a distributed set of interacting neural regions. The DIVA (Directions into Velocities of Articulators) neurocomputational model elaborates on early theories, integrating existing data and contemporary ideologies, to provide a mechanistic account of acoustic, kinematic, and functional magnetic resonance imaging (fMRI) data on speech acquisition and production. This large-scale neural network model is composed of several interconnected components whose cell activities and synaptic weight strengths are governed by differential equations. Cells in the model are associated with neuroanatomical substrates and have been mapped to locations in Montreal Neurological Institute stereotactic space, providing a means to compare simulated and empirical fMRI data. The DIVA model also provides a computational and neurophysiological framework within which to interpret and organize research on speech acquisition and production in fluent and dysfluent child and adult speakers. The purpose of this review article is to demonstrate how the DIVA model is used to motivate and guide functional imaging studies. We describe how model predictions are evaluated using voxel-based, region-of-interest-based parametric analyses and inter-regional effective connectivity modeling of fMRI data. (C) 2009 Elsevier Inc.

TI Transformations in oscillatory activity and evoked responses in primary somatosensory cortex in middle age: A combined computational neural modeling and MEG study SO NEUROIMAGE LA English DT Article ID MEDIAN NERVE-STIMULATION; SENSORIMOTOR CORTEX; MU-RHYTHM; QUANTITATIVE-ANALYSIS; SCALP TOPOGRAPHY; PHASE SYNCHRONY; HEALTHY-ADULTS; CENTRAL SULCUS; ALPHA-RHYTHMS; OLDER-ADULTS AB Oscillatory brain rhythms and evoked responses are widely believed to impact cognition, but relatively little is known about how these measures are affected by healthy aging. The present study used MEG to examine age-related changes in spontaneous oscillations and tactile evoked responses in primary somatosensory cortex (SI) in healthy young (YA) and middle-aged (MA) adults. To make specific predictions about neurophysiological changes that mediate age-related MEG changes, we applied a biophysically realistic model of SI that accurately reproduces SI MEG mu rhythms, containing alpha (7-14 Hz) and beta (15-30 Hz) components, and evoked responses. Analyses of MEG data revealed a significant increase in prestimulus mu power in SI, driven predominately by greater mu-beta dominance, and a larger and delayed M70 peak in the SI evoked response in MA. Previous analysis with our computational model showed that the SI mu rhythm could be reproduced with a stochastic sequence of rhythmic similar to 10 Hz feedforward (FF) input to the granular layers of SI (representative of lemniscal thalamic input) followed nearly simultaneously by similar to 10 Hz feedback (FB) input to the supragranular layers (representative of input from high order cortical or non-specific thalamic sources) (Jones et al., 2009). In the present study, the model further predicted that the rhythmic FF and FB inputs become stronger with age. Further, the FB input is predicted to arrive more synchronously to SI on each cycle of the 10 Hz input in MA. The simulated neurophysiological changes are sufficient to account for the age-related differences in both prestimulus mu rhythms and evoked responses. Thus, the model predicts that a single set of neurophysiological changes intimately links these age-related changes in neural dynamics. (C) 2010 Elsevier Inc. All rights reserved.

TI A comprehensive analysis of deletions, multiplications, and copy number variations in PARK2 SO NEUROLOGY LA English DT Article ID ONSET PARKINSONS-DISEASE; RECESSIVE JUVENILE PARKINSONISM; DEPENDENT PROBE AMPLIFICATION; ALPHA-SYNUCLEIN; GENE; MUTATIONS; ASSOCIATION; HETEROZYGOSITY; SUSCEPTIBILITY; REARRANGEMENTS AB Objectives: To perform a comprehensive population genetic study of PARK2. PARK2 mutations are associated with juvenile parkinsonism, Alzheimer disease, cancer, leprosy, and diabetes mellitus, yet ironically, there has been no comprehensive study of PARK2 in control subjects; and to resolve controversial association of PARK2 heterozygous mutations with Parkinson disease (PD) in a well-powered study. Methods: We studied 1,686 control subjects (mean age 66.1 +/- 13.1 years) and 2,091 patients with PD (mean onset age 58.3 +/- 12.1 years). We tested for PARK2 deletions/multiplications/copy number variations (CNV) using semiquantitative PCR and multiplex ligation-dependent probe amplification, and validated the mutations by real-time quantitative PCR. Subjects were tested for point mutations previously. Association with PD was tested as PARK2 main effect, and in combination with known PD risk factors: SNCA, MAPT, APOE, smoking, and coffee intake. Results: A total of 0.95% of control subjects and 0.86% of patients carried a heterozygous CNV mutation. CNV mutations found in 16 control subjects were all in exons 1-4, sparing exons that encode functionally critical protein domains. Thirteen patients had 2 CNV mutations, 5 had 1 CNV and 1 point mutation, and 18 had 1 CNV mutation. Mutations found in patients spanned exons 2-9. In whites, having 1 CNV was not associated with increased risk (odds ratio 1.05, p = 0.89) or earlier onset of PD (64.7 +/- 8.6 heterozygous vs 58.5 +/- 11.8 normal). Conclusions: This comprehensive population genetic study in control subjects fills the void for a PARK2 reference dataset. There is no compelling evidence for association of heterozygous PARK2 mutations, by themselves or in combination with known risk factors, with PD.

TI Nonsteroidal anti-inflammatory drugs are associated with increased neuritic plaques SO NEUROLOGY LA English DT Article ID RANDOMIZED CONTROLLED-TRIAL; ALZHEIMERS-DISEASE; COGNITIVE IMPAIRMENT; PARKINSONS-DISEASE; DEMENTIA; RISK; PATHOLOGY; ROFECOXIB; NEUROPATHOLOGY; METAANALYSIS AB Objectives: Observational and experimental studies suggest that nonsteroidal anti-inflammatory drugs (NSAIDs) may protect against Alzheimer disease (AD); however, clinical trials and other observational studies, including the Adult Changes in Thought (ACT) study, show no protection or promotion of AD. The objective of this study is to determine the relationship between common dementia-associated pathologies and mid-to late-life NSAID exposure. Methods: We examined the association of mid-to late-life NSAID use with neuropathologic findings on 257 autopsies from ACT, a population-based study of brain aging and incident dementia. Cumulative standard daily doses (SDD) of nonselective NSAIDs were determined from >= 10 years of computerized pharmacy dispensing data. Analyses were adjusted for selection bias to broaden generalizability of results to 3,026 eligible participants in the ACT cohort. Seven pathologic indices were evaluated: intermediate or frequent score for neuritic plaques, Braak stages V or VI for neurofibrillary tangles, >2 cerebral microinfarcts, the presence of any neocortical Lewy bodies, any macroscopic infarcts, any amyloid angiopathy, and moderate or severe atherosclerosis. Results: Of the neuropathologic indices evaluated, only neuritic plaque score was significantly increased in participants with greater use of nonselective NSAIDs (p = 0.065), specifically in those with high levels of cumulative use: 1,000-2,000 SDD (adjusted relative risk [RR] 2.16, 95% confidence interval [CI] 1.02-4.25, compared to light/nonuse [ <60 SDD]) and >2,000 SDD (adjusted RR 2.37, 95% CI 1.24-4.67). Conclusions: Increased neuritic plaque accumulation may explain the association between heavy use of nonselective NSAIDs and increased risk of dementia among ACT participants.

TI Detection of increased scyllo-inositol in brain with magnetic resonance spectroscopy after dietary supplementation in Alzheimer's disease mouse models SO NEUROPHARMACOLOGY LA English DT Article DE Alzheimer's disease; Scyllo-inositol; Transgenic mouse; MRS; Magic angle spinning ID A-BETA; TRANSGENIC MICE; PLAQUES; IDENTIFICATION; MYOINOSITOL; METABOLISM; TRANSPORT; PROFILE; H-1; MRS AB There is evidence that inositol isomers may help protect against formation of toxic fibrils of All fragments in Alzheimer's disease mouse models. Scyllo-inositol is one of the more promising inositol isomers for the potential treatment of Alzheimer's disease (AD) and can be detected using MRS in human subjects. In this manuscript we demonstrate using MRS, in two different mouse models of AD (APP x PS1 and APP x PS1 x tau), that we could detect increased scyllo-inositol in the hippocampus and frontal cortex in mice fed water supplemented with 16.5 mg/L of scyllo-inositol equivalent to about 3.3 mg/kg/day. We used both brain extracts using solution MRS as well as intact brain tissue using high resolution magic angle spinning (HRMAS) to ensure that any membrane-associated scyllo-inositol would be detected. By brain extracts we detected a 3.0 fold increase in scyllo-inositol in the scyllo-fed AD mice compared to normal diet (p < 0.001). Using HRMAS we detected a 2.2-2.4-fold increase in scyllo-inositol (p < 0.001). Scyllo-inositol treatment was associated with an increase in glutamine in hippocampus. The concentrations of scyllo-inositol were higher in the hippocampus than in the frontal cortex. Mice have a smaller concentration of scyllo-inositol than humans (ca. 100 mu M vs. 500 mu M in humans). Given the ease with which scyllo-inositol can be measured in human MRS data with high signal to noise ratios, these data suggest that MRS will prove useful for evaluation of inositol treatment trials in AD subjects.

This essay traces the historical evolution of this line of inquiry from an emerging field to its current status, with personal reflections over almost three decades on this journey of discovery. It pays tribute to early investigators who recognized the wider role of the cerebellum beyond motor control, traces the origins of new terms and concepts including the dysmetria of thought theory, the universal cerebellar transform, and the cerebellar cognitive affective syndrome, and places these developments within the broader context of the scientific efforts of a growing community of cerebellar cognitive neuroscientists. This account considers the converging evidence from theoretical, anatomical, physiological, clinical, and functional neuroimaging approaches that have resulted in the transition from recognizing the cerebellar incorporation into the distributed neural circuits subserving cognition and emotion, to a hopeful new era of treatment of neurocognitive and neuropsychiatric manifestations of cerebellar diseases, and to cerebellar-based interventions for psychiatric disorders.

We present a case of a large, broad-based aneurysm arising from a proximal basilar artery (BA) fenestration treated with the waffle-cone technique. Technical nuances and indications for this treatment option are reviewed. CLINICAL PRESENTATION: A 38-year-old man presented with headache, blurred vision, and dizziness. Angiography demonstrated an 11 x 14-mm BA aneurysm associated with the proximal portion of a BA fenestration. TECHNIQUE: A 28 x 4.5-mm Enterprise stent was placed from the right vertebral artery directly into the aneurysm. The stent tines were allowed to flare out in the aneurysm neck creating the "waffle cone." The aneurysm was then coiled with a series of Presidio coils. CONCLUSION: Use of the waffle-cone technique for stent placement resulted in nearly complete embolization of the aneurysm, retention of the entire coil mass in the dome, and preservation of flow through both vertebral arteries and both limbs of the fenestration.

Although little is known about the long-term neurobehavioral or neurophysiological effects of low-dose exposure to GB/GF in humans, recent studies of GW veterans from the Devens Cohort suggest decrements in certain cognitive domains and atrophy in brain white matter occur individuals with higher estimated levels of presumed GB/GF exposure. The goal of the current study is to determine the generalizability of these findings in another cohort of GW veterans with suspected GB/GF exposure. Methods: Neurobehavioral and imaging data collected in a study on Gulf War Illness between 2002 and 2007 were used in this study. We focused on the data of 40 GW-deployed veterans categorized as having been exposed to GB/GF at Khamisiyah, Iraq and 40 matched controls. Magnetic resonance images (MRI) of the brain were analyzed using automated and semi-automated image processing techniques that produced volumetric measurements of gray matter (GM), white matter (WM), cerebrospinal fluid (CSF) and hippocampus. Results: GW veterans with suspected GB/GF exposure had reduced total GM and hippocampal volumes compared to their unexposed peers (p <= 0.01). Although there were no group differences in measures of cognitive function or total WM volume, there were significant, positive correlations between total WM volume and measures of executive function and visuospatial abilities in veterans with suspected GB/GF exposure. Conclusions: These findings suggest that low-level exposure to GB/GF can have deleterious effects on brain structure and brain function more than decade later. (C) 2010 Elsevier Inc.

TI Effects of a Low-intensity Intervention That Prescribed a Low-carbohydrate vs. a Low-fat Diet in Obese, Diabetic Participants SO OBESITY LA English DT Article ID RANDOMIZED-TRIAL; WEIGHT-LOSS; FOLLOW-UP; REDUCTION; PROTEIN; ADVICE; ADULTS AB Low-carbohydrate diets have been associated with significant reductions in weight and HbA(1c) in obese, diabetic participants who received high-intensity lifestyle modification for 6 or 12 months. This investigation sought to determine whether comparable results to those of short-term, intensive interventions could be achieved over a 24-month study period using a low-intensity intervention that approximates what is feasible in outpatient practice. A total of 144 obese, diabetic participants were randomly assigned to a low-carbohydrate diet (<30 g/day) or to a low-fat diet (<= 30% of calories from fat with a deficit of 500 kcal/day). Participants were provided weekly group nutrition education sessions for the first month, and monthly sessions thereafter through the end of 24 months. Weight, HbA(1c), glucose, and lipids were measured at baseline and 6, 12, and 24 months. Of the 144 enrolled participants, 68 returned for the month 24 assessment visit. Weights were retrieved from electronic medical records for an additional 57 participants (total, 125 participants) at month 24. All participants with a baseline measurement and at least one of the three other measurements were included in the mixed-model analyses (n = 138). The low-intensity intervention resulted in modest weight loss in both groups at month 24. At this time, participants in the low-carbohydrate group lost 1.5 kg, compared to 0.2 kg in the low-fat group (P = 0.147). Lipids, glycemic indexes, and dietary intake did not differ between groups at month 24 (or at months 6 or 12) C1 [Iqbal, Nayyar; Vetter, Marion L.; Dalton-Bakes, Cornelia V.; Cardillo, Serena] Hosp Univ Penn, Dept Med, Div Endocrinol Diabet & Metab, Philadelphia, PA 19104 USA.

TI Insulin Resistance is the Best Predictor of the Metabolic Syndrome in Subjects With a First-Degree Relative With Type 2 Diabetes SO OBESITY LA English DT Article ID BODY-MASS INDEX; CORONARY-HEART-DISEASE; CARDIOVASCULAR-DISEASE; WAIST CIRCUMFERENCE; CARDIOMETABOLIC RISK; GLUCOSE-TOLERANCE; NORMAL-WEIGHT; OBESITY; MEN; DEFINITION AB Although obesity is associated with insulin resistance and the metabolic syndrome (MetS), some obese individuals are metabolically healthy. Conversely, some lean individuals are insulin resistant (IR) and at increased cardiometabolic risk. To determine the relative importance of insulin sensitivity, BMI and waist circumference (WC) in predicting MetS, we studied these two extreme groups in a high-risk population. One thousand seven hundred and sixty six subjects with a first-degree relative with type 2 diabetes were stratified by BMI and homeostasis model assessment of insulin resistance (HOMA(IR)) into groups. IR groups had higher triglycerides, fasting glucose, and more diabetes than their BMI-group insulin sensitive (IS) counterparts. Within both IS and IR groups, obesity was associated with higher HOMA(IR) and diastolic blood pressure (BP), but no difference in other metabolic variables. MetS (Adult Treatment Panel III (ATPIII)) prevalence was higher in IR groups (P < 0.001) and more subjects met each MetS criterion (P < 0.001). Within each BMI category, HOMA(IR) independently predicted MetS (P < 0.001) whereas WC did not. Within IS and IR groups, age and WC, but not BMI, were independent determinants of MetS (P < 0.001). WC was a less meaningful predictor of MetS at higher values of HOMA(IR). HOMA(IR) was a better predictor of MetS than WC or BMI (receiver operating characteristic (ROC) area under the curve 0.76 vs. 0.65 vs. 0.59, P < 0.001). In conclusion, insulin sensitivity rather than obesity is the major predictor of MetS and is better than WC at identifying obese individuals with a healthier metabolic profile. Further, as many lean individuals with a first-degree relative with type 2 diabetes are IR and metabolically unhealthy, they may all benefit from metabolic testing.

TI Glucagon Treatment for Post-Gastric Bypass Hypoglycemia SO OBESITY LA English DT Article ID HYPERINSULINEMIC HYPOGLYCEMIA; NESIDIOBLASTOSIS; PANCREATECTOMY; SURGERY; GLUCOSE AB Hyperinsulinemic hypoglycemia is a recently described complication of Roux-en-Y gastric bypass (RYGB). We hypothesized that glucagon administration would help maintain normal postprandial plasma glucose concentrations by stimulating hepatic glucose output, and if so, represent a new therapeutic option for postbypass hypoglycemia. In this study, we compared the insulin and glycemic response to a mixed meal with and without concomitant glucagon infusion in a patient with severe recurrent hypoglycemia after RYGB. Although effective in transiently raising postprandial plasma glucose values, glucagon infusion was also associated with higher insulin concentrations, and failed to prevent symptomatic hypoglycemia. This case demonstrates that glucagon may have limited clinical utility in the treatment of post-RYGB hyperinsulinemic hypoglycemia.

TI Comparing the Second Stage in Induced and Spontaneous Labor SO OBSTETRICS AND GYNECOLOGY LA English DT Article; Proceedings Paper CT 57th Annual Meeting of the Society-for-Gynecologic-Investigation CY MAR 24-27, 2010 CL Orlando, FL SP Soc Gynecol Investigat ID RANDOMIZED CONTROLLED-TRIAL; ELECTIVE INDUCTION; NEONATAL OUTCOMES; EXPECTANT MANAGEMENT; POSTTERM PREGNANCY; MULTIPAROUS WOMEN; PROGRESSION AB OBJECTIVE: To compare the duration and complications of the second stage of labor between women in induced and spontaneous labor. METHODS: This was a retrospective cohort study of women with singleton term gestations who reached full dilation at a single institution from 2001 through 2009. Second-stage duration, mode of delivery, and complication rates were compared between women in induced and spontaneous labor using survival analysis, univariable analysis, and multivariable analyses to control for potential confounders. RESULTS: We identified 14,727 women who reached the second stage; 3,139 (21.3%) were induced and 11,588 (78.7%) were in spontaneous labor. After adjusting for confounders (maternal age, body mass index, epidural use, gestational age, midwifery care, health center care, year of delivery), there was no difference in length of the second stage or risk of a prolonged second stage between women in induced and spontaneous labor. In both groups, risk of complications increased with duration of the second stage, including chorioamnionitis, postpartum hemorrhage, third-or fourth-degree laceration, operative vaginal delivery, and 5-minute Apgar score less than 7. Among nulliparas who reached full dilation, our data suggested an increased odds of cesarean (10.9% compared with 7.2%, adjusted odds ratio [OR] 1.32, 95% confidence interval [CI] 1.01-1.71) and postpartum hemorrhage (4.2% compared with 2.0%, adjusted OR 1.62, 95% CI 1.02-2.58) with induction. There was no differ-ence in mode of delivery or rates of complications among multiparas. CONCLUSION: Among women who reach full dilation, labor proceeds similarly regardless of induction status. Induced nulliparas may have an increased risk of hemorrhage and cesarean delivery.

Current evidence indicates that during hepatocarcinogenesis, two main pathogenic mechanisms prevail: (1) cirrhosis associated with hepatic regeneration after tissue damage caused by hepatitis infection, toxins (for example, alcohol or aflatoxin) or metabolic influences, and (2) mutations occurring in single or multiple oncogenes or tumor suppressor genes. Both mechanisms have been linked with alterations in several important cellular signaling pathways. These pathways are of interest from a therapeutic perspective, because targeting them may help to reverse, delay or prevent tumorigenesis. In this review, we explore some of the major pathways implicated in HCC. These include the RAF/MEK/ERK pathway, phosphatidylinositol-3 kinase (PI3K)/AKT/ mammalian target of rapamycin (mTOR) pathway, WNT/beta-catenin pathway, insulin-like growth factor pathway, hepatocyte growth factor/c-MET pathway and growth factor-regulated angiogenic signaling.

There are several FLT3 inhibitors presently in clinical trials with sufficient efficacy and toxicity features to warrant further testing in combination with standard therapies. However, the transient and partial responses observed in AML patients treated with FLT3 inhibitors, coupled with the discovery of drug-resistant leukemic blast cells in AML patients, have made resistance to FLT3 inhibitors a growing concern. In this study, we provide an overview of the role of mutant FLT3 in AML, FLT3 inhibitors under clinical and preclinical investigation, mechanisms of resistance to FLT3 inhibitors, and possible therapeutic approaches to overcoming this resistance.

TI H1047R phosphatidylinositol 3-kinase mutant enhances HER2-mediated transformation by heregulin production and activation of HER3 SO ONCOGENE LA English DT Article DE PIK3CA mutations; HER2 overexpression; HER3; heregulin; breast cancer ID HUMAN BREAST-CANCER; TYROSINE KINASE INHIBITORS; GROWTH-FACTOR RECEPTOR; PIK3CA MUTATIONS; PHOSPHOINOSITIDE 3-KINASE; IN-VIVO; TRASTUZUMAB RESISTANCE; EPITHELIAL-CELLS; HIGH-FREQUENCY; PI3K PATHWAY AB Hyperactivation of phosphatidylinositol-3 kinase (PI3K) can occur as a result of somatic mutations in PIK3CA, the gene encoding the p110 alpha subunit of PI3K. The HER2 oncogene is amplified in 25% of all breast cancers and some of these tumors also harbor PIK3CA mutations. We examined mechanisms by which mutant PI3K can enhance transformation and confer resistance to HER2-directed therapies. We introduced the PI3K mutations E545K and H1047R in MCF10A human mammary epithelial cells that also overexpress HER2. Both mutants conferred a gain of function to MCF10A/HER2 cells. Expression of H1047R PI3K, but not E545K PI3K, markedly upregulated the HER3/HER4 ligand heregulin (HRG). HRG siRNA inhibited growth of H1047R but not E545K-expressing cells and synergized with the HER2 inhibitors trastuzumab and lapatinib. The PI3K inhibitor BEZ235 markedly inhibited HRG and pAKT levels and, in combination with lapatinib, completely inhibited growth of cells expressing H1047R PI3K. These observations suggest that PI3K mutants enhance HER2-mediated transformation by amplifying the ligand-induced signaling output of the ErbB network. This also counteracts the full effect of therapeutic inhibitors of HER2. These data also suggest that mammary tumors that contain both HER2 gene amplification and PIK3CA mutations should be treated with a combination of HER2 and PI3K inhibitors.

It is a heterogeneous collection of diagnoses with varied clinical courses and outcomes. The majority of PTLD is Epstein-Barr virus (EBV)-driven as a result of loss of immune control of EBV-positive B lymphocytes. Risk factors for the development of PTLD thus reflect loss or absence of EBV immunity; they include younger age and pre-transplant EBV naivety, as well as the degree and type of immune suppression, type of organ transplantation, and time from transplantation. Identifying patients at risk for PTLD and developing strategies to prevent PTLD is the subject of much research, and the use of antiviral medications and EBV vaccines has yielded intriguing, albeit preliminary, results. As we learn more about the prognostic factors affecting outcome and the pathogenesis of individual diseases, we are better able to tailor therapy to the individual. Further clinical investigation, including randomized controlled trials, will be important in reaching this goal.

TI Ocular manifestations of Fabry disease within in a single kindred SO OPTOMETRY-JOURNAL OF THE AMERICAN OPTOMETRIC ASSOCIATION LA English DT Article DE Fabry disease; Ocular manifestations; Optical coherence tomography; Corneal verticillata ID ALPHA-GALACTOSIDASE; CLINICAL-MANIFESTATIONS; OUTCOME SURVEY; CORNEAL THICKNESS; FEMALES; STORAGE; DIAGNOSIS; COHORT; REPLACEMENT; DEFICIENCY AB BACKGROUND: Fabry disease is an X-linked lysosomal storage disorder that causes progressive complications within the kidneys, brain, and heart. Ocular manifestations of this disease are often present at a very young age, thereby facilitating early diagnosis, before the signs and symptoms of renal disease, stroke, or hypertrophic cardiomyopathy. Early diagnosis by the eye care provider may eventually reduce the morbidity and mortality of this disease through the institution of therapy before the development of sclerotic end organ damage. This study evaluated 23 Fabry-affected members of a single cohort for the presence of ocular signs of Fabry disease. METHODS: Twenty-three patients of a single family were seen on a single day. Patients were given comprehensive ophthalmic examinations and completed a health and lifestyle questionnaire. RESULTS: Eight hemizygous men (mean age, 32.3 years) and 15 heterozygous women (mean age, 26.9 years) from a single family of 43 known Fabry patients were evaluated. Corneal verticillata was present in all patients. Additional findings in the male patients included anterior capsule opacity (25% total) and Fabry cataract (12.5%). Thinning of the retinal nerve fiber layer was observed in one man whose medical history was significant for stroke. Conjunctival and/or retinal vessel tortuosity was present in the majority of patients (62.5% and 75% of hemizygotes, respectively; 40% and 13.3% heterozygotes, respectively). Additional findings in the women included anterior capsule opacity. The majority of patients (87.5% hemizygotes, 60% heterozygotes) felt Fabry disease had an impact on their quality of life. CONCLUSIONS: All evaluated patients who had Fabry disease had corneal verticillata, which generally does not affect vision and is readily recognizable by slit lamp examination. Greater than 60% showed conjunctival and/or retinal vessel tortuosity. The eye care provider can play a crucial role in the early recognition of ocular manifestations of Fabry disease and decrease both the time to accurate diagnosis and the delay in the institution of disease-modifying therapy.

TI On the frontline: What an optometrist needs to know about myasthenia gravis SO OPTOMETRY-JOURNAL OF THE AMERICAN OPTOMETRIC ASSOCIATION LA English DT Article DE Myasthenia gravis; Ocular myasthenia; Myogenic ptosis; Ptosis crutch ID OCULAR MYASTHENIA; INTRAVENOUS IMMUNOGLOBULIN; ICE TEST; PTOSIS; BLEPHAROPTOSIS; THYMECTOMY; MANAGEMENT; THERAPY; THYMUS AB BACKGROUND: Myasthenia gravis (MG) is an autoimmune disease that affects the voluntary skeletal muscles. It is characterized by transient weakness of the muscles that improves with rest. Muscle weakness involving the eyes can produce signs or symptoms of diplopia, blurred vision, ptosis, and ophthalmoplegia. Ptosis is defined as an abnormal eyelid "drooping" beyond the normal I to 2 mm of the upper limbus of the cornea. Hence, most patients with MG have ophthalmic manifestations. Among all patients with MG, up to half will have exclusively ocular symptoms. In these cases, the condition is referred to as ocular myasthenia. CASE REPORT: A 60-year-old man was referred from a neurology clinic for management of intermittent diplopia for greater than 1 year and intermittent bilateral ptosis for the prior year. He reported that he first noticed symptoms of MG at the age of 42, but did not receive the diagnosis until 1 year before his aforementioned neurology examination. He was prescribed spectacles with bilateral ptosis crutches. A diagnosis of severe seronegative MG was subsequently confirmed with neurologic examination and antibody testing. CONCLUSIONS: Because patients with undiagnosed myasthenia gravis may present initially with ocular signs or symptoms, it is important for the optometrist to be familiar with the condition and the simple "in-office" tests that can be performed to establish a tentative diagnosis and management plan. The optometrist can also participate in the management of ocular manifestations of myasthenia and should be familiar with the use of a ptosis crutch (in addition to prism spectacles or occlusion therapies if indicated) as a nonsurgical intervention for ptosis.

We sought to examine whether vascular disease was associated with lumbar spine facet joint osteoarthritis (FJ OA) in a community-based population. Design: 441 participants from the Framingham Heart Study multi-detector computed tomography (MDCT) Study were included in this ancillary study. We used a quantitative summary measure of abdominal aortic calcification (ARC) from the parent study as a marker for vascular disease. RAC was categorized into tertiles of 'no' (reference), 'low', and 'high' calcification. FJ OR was evaluated on computerised tomography (CT) scans using a four-grade scale. For analytic purposes, FJ OR was dichotomized as moderate FJ OA of at least one joint from L2-S1 vs no moderate FJ OA. We examined the association of AAC and FJ OA using logistic regression before and after adjusting for age, sex and body mass index (BMI). Furthermore, we examined the independent effect of AAC on FJ OA after including the known cardiovascular risk factors; diabetes, hypertension, hypercholesterolemia, and smoking. Results: Low ARC (OR 3.84 [2.33-6.34]; P <= 0.0001) and high ARC (9.84 [5.29-18.3]; <= 0.0001) were strongly associated with FJ OA, compared with the reference group. After adjusting for age, sex, and BMI, the association with FJ OR was attenuated for both low ARC (1.81 [1.01-3.27]; P=0.05) and high ARC (2.63 [0.99-5.23]; P=0.05). BMI and age were independently and significantly associated with FJ OA. The addition of cardiovascular risk factors to the model did not substantially change parameter estimates for either AAC tertile. Conclusions: AACs were associated with FJ OA in this community-based population, when adjusting for epidemiologic factors associated with spinal degeneration, and cardiovascular risk factors. Potentially modifiable risk factors for facet degeneration unrelated to conventional biomechanical paradigms may exist. This study is limited by cross-sectional design; longitudinal studies are needed.

STUDY DESIGN: Case series with chart review. SETTING: Tertiary care center. SUBJECTS AND METHODS: Head and neck squamous cell carcinoma patients undergoing neck dissection after chemoradiotherapy between January 1998 and June 2008. We compared computed tomography findings after chemoradiotherapy with neck dissection pathology results; used primary location and computed tomography findings to design selective or superselective neck dissection; and determined whether these surgeries would have contained all metastatic disease. RESULTS: A total of 104 patients were identified, providing 110 heminecks, 531 neck levels, and 3009 lymph nodes for analysis. Neck dissections were positive in 20 (19%) of 104 patients, corresponding to 20 hemineck dissections, 31 neck levels, and 53 lymph nodes. The negative predictive value for computed tomography was 95 percent. The negative predictive value for computed tomography per neck level was as follows: I, 100 percent; 11, 96 percent; 111, 96 percent; IV, 97 percent; and V. 96 percent. A selective neck dissection or a superselective neck dissection, guided by level specific computed tomography findings and limited to necks with post treatment partial response in one level, would have captured all disease in 52 (95%) of 55 and 51(93%) of 55 heminecks. CONCLUSION: Negative computed tomography accurately predicts pathologic complete response at neck dissection. Neck dissection can be avoided in these patients. Additionally, computed tomography reliably identifies low risk neck levels that do not require dissection, permitting selective neck dissection or superselective neck dissection in partial response patients with limited residual disease.

STUDY DESIGN: Case series with chart review. SETTING: An otolaryngology and ophthalmology specialty hospital. SUBJECTS AND METHODS: Fifty-three patients were treated between 1994 and 2008 for orbital or subperiosteal abscess and paranasal sinusitis, confirmed by imaging and surgical intervention; 46 had operative culture specimens and comprise the study cohort. RESULTS: The mean patient age was 28 years; one third were younger than 18. Nearly twice as many patients had subperiosteal (n = 30) as had orbital abscesses (n = 16). In 12 patients (26%), cultures were negative or grew only skin flora contaminants (coagulase-negative staphylococci, diphtheroids, and Propionibacterium acnes). Fifteen patients (33%) grew more than one pathogen. Streptococci were isolated in 17 of the 46 cases (37%), S. aureus in 13 (28.3%), gram-negative bacilli in eight (17.4%), and anaerobes in nine (19.6%). Methicillin-resistant S. aureus accounted for three (23.1%) of the S. aureus isolates and 6.5 percent of the total cases. CONCLUSION: Abscess cultures grew a mixture of bacteria, including gram-positive cocci, gram-negative bacilli, and anaerobes. Although streptococci were the most common genus of bacteria isolated, S. aureus was the single most common pathogen recovered and one fourth of these cases were methicillin-resistant S. aureus. Given the significant morbidity that may result from inadequate treatment, an antibiotic active against methicillin-resistant S. aureus should be included in the initial broad-spectrum antimicrobial treatment regimen of orbital and subperiosteal abscesses of sinusitis origin until culture results are available.

We sought to determine the activity of erlotinib for progressive vestibular schwannoma (VS) associated with neurofibromatosis 2 (NF2). Study Design: Retrospective case review. Setting: Tertiary referral center. Patients: Eleven NF2 patients with progressive VS who were poor candidates for standard therapy. Intervention: Erlotinib 150 mg daily. Main Outcome Measures: A radiographic response was defined as >= 20% decrease in tumor volume compared with baseline. A hearing response was defined as a statistically significant increase in word recognition score (WRS) compared with baseline; a minor hearing response was defined as a 10 dB improvement in pure-tone average with stable WRS. Results: Before treatment, the median and mean annual volumetric growth rate for 11 index VS were 26% and 46%, respectively. Among 10 evaluable patients, the median time-to-tumor progression was 9.2 months. Three patients with stable disease experienced maximum tumor shrinkage of 4%, 13%, and 14%. Nine patients underwent audiologic evaluations. One experienced a transient hearing response, 2 experienced minor hearing responses, 3 remained stable, and 2 developed progressive hearing loss. The median time-to-progressive hearing loss was 9.2 months and to either tumor growth or progressive hearing loss was 7.1 months. Adverse treatment effects included mild-to-moderate rash, diarrhea, and hair thinning, with 2 episodes of grade 3 toxicity. Conclusion: Erlotinib treatment was not associated with radiographic or hearing responses in NF2 patients with progressive VS. Because a subset of patients experienced prolonged stable disease, time-to-progression may be more appropriate than radiographic or hearing response for anti-EGFR agents in NF2-associated VS.

Patients: Case report of a patient on immunosuppressive therapy with facial nerve weakness 3 years after last resection for multiple recurrent pleomorphic adenoma. Interventions: Computed tomography and magnetic resonance imaging followed by surgical exploration, resection, and reconstruction. Main Outcome Measures: Histopathologic diagnosis and treatment outcome. Results: Final diagnosis of recurrent pleomorphic adenoma causing compression of the facial nerve at the stylomastoid foramen. Conclusion: Facial nerve weakness caused by a benign salivary gland tumor is rare. Although alternate diagnoses must be considered, recurrent pleomorphic adenoma alone may impair facial function by impinging on the nerve in the stylomastoid foramen.

Background: Evidence from comparative effectiveness research (CER) can be used to guide decisions regarding health care and to improve quality and efficiency of care. We propose to develop the infrastructure required to conduct CER across an extensive network of NPF Centers of Excellence. Methods: We present the staged planning for a pilot study which will demonstrate the development and implementation of the infrastructure that will be needed for a large standardized patient-centered, clinical practice database for PD. This database will support CER and drive quality improvement studies. Results: We describe the infrastructure for the ongoing pilot feasibility testing in a subset of six NPF Centers of Excellence, and we discuss the impact that the data (available in 2010) could have in guiding PD management. Conclusion: This preliminary experience will facilitate the longitudinal tracking of therapies and of outcomes in PD clinical practice. Further, we are hopeful that the information will provide insight into PD that will extend beyond the clinical trials population (the population included in most available PD databases). This prospective standardized real-world multi-center clinical practice database will aim to identify positive health outcomes associated with treatment approaches, and to identify variations in clinical outcomes that may suggest improvements in best clinical practice patterns.

We describe rapidly progressive PRES following stem cell transplant for acute lymphoblastic leukemia. After development of altered mental status, this 8-year-old girl had T2 prolongation of the white matter in a posterior-dominant distribution, eventually developing cerebellar edema, hemorrhage, hydrocephalus, and herniation. Despite surgical and medical management, she died 36 hours later. At autopsy, the occipital and cerebellar white matter and focal occipital cortical gray matter showed a spectrum of microvascular changes, including dilated perivascular spaces containing proteinaceous exudates and macrophages, as well as fibrinoid necrosis and acute hemorrhage, in a distribution corresponding to the neuroimaging abnormalities and reminiscent of those seen in patients with acute hypertensive encephalopathy. Of note, similar microvascular changes were not seen in the kidney or other systemic sites. Thus, the findings indicate a brain-specific microvascular compromise as the substrate of PRES, at least in the rare instance of cases progressing to fatal outcome.

Platinating agents are used in the treatment of a spectrum of childhood cancers. Oxaliplatin, a third generation platinum compound, may provide less toxicity and be more effective. A phase 2 study was performed to estimate the response rate to single agent oxaliplatin in patients with refractory pediatric solid tumors, and to further describe the toxicities and pharmacokinetics of the drug in this population. Patients and Methods. Subjects, <= 21 years of age at original diagnosis, received oxaliplatin (130 mg/m(2)) intravenously every 21 days. Prior platinum exposure was acceptable. Histologies included: Ewing sarcoma/peripheral PNET, osteosarcoma, rhabdomyosarcoma, neuroblastoma, high and low grade astrocytoma, brain stem glioma, ependymoma, hepatoblastoma and selected rare tumors. A two-stage design, enrolling 10 + 10 subjects, was used for each disease stratum. Limited sampling pharmacokinetic studies were performed. Results. Of 124 eligible subjects (75 males), 113 were evaluable for response and 69 (62%) had received platinum previously. Only one objective response was observed, a partial response in a 6-year-old child with ependymoma. An additional 13 subjects with various other solid tumors had stable disease, receiving a median (range) of 13.5 (2-17) cycles. Five subjects completed 17 treatment cycles. Thrombocytopenia was the most common toxicity observed. The median (range) terminal half-life and clearance for ultrafiltrable platinum were 293 (187-662 hr) and 14.0 (1.9-24.9 Uhr/m(2)), respectively (n = 49). Conclusions. Although reasonably well tolerated, oxaliplatin administered as a single agent has limited activity in pediatric patients with relapsed or refractory solid tumors. Pediatr Blood Cancer.

TI Self-Reported Acne Severity, Treatment, and Belief Patterns across Multiple Racial and Ethnic Groups in Adolescent Students SO PEDIATRIC DERMATOLOGY LA English DT Article ID HIGH-SCHOOL-STUDENTS; VULGARIS; PREVALENCE; PERCEPTIONS; MAMMOGRAPHY; CARE AB Acne vulgaris is a common condition among adolescents regardless of age, gender, and race. We compare the frequency, severity, help-seeking behavior, treatment, and beliefs about acne among students based on race, ethnicity, gender, and age. Anonymous surveys were administered to 1,214 students aged 10-19 years of varied gender, race, and ethnicity in public middle and high schools in New Jersey. Results showed the frequency and severity of acne were high (76% and 65%, respectively) and more prevalent in white compared to non-white respondents (RR = 1.13, 95% CI = 1.04-1.24 and RR = 1.22, 95% CI = 1.09-1.37, respectively), and also in older compared to younger ages (RR = 1.24, 95% CI = 1.17-1.32 and RR = 1.43, 95% CI = 1.32-1.55, respectively). The majority of respondents (83%) reported never having seen a physician for their acne; however, those reporting acne of some severity were more likely to have seen a physician compared with those who did not report acne (21% vs. 8%, p < 0.001). Blacks who reported mild or moderate severity of acne were more likely to have seen a health professional compared to white respondents with same the acne severity (RR = 3.63, 95% CI = 2.06-6.37 and RR = 3.06, 95% CI = 2.02-4.65, respectively). Conversely, Hispanic respondents with mild or moderate acne were less likely to have seen a health professional compared to whites with the same acne severity (RR = 0.56, 95% CI = 0.35-0.89 and RR = 0.47, 95% CI = 0.26-0.86, respectively). Beliefs about external factors affecting acne also varied by race and ethnicity. In conclusion, the severity, frequency, and beliefs about acne all play a role in help-seeking behaviors, which vary to a significant extent by race and ethnicity.

The ghrelin-acylating enzyme, ghrelin-O-acyltransferase (GOAT) involved in the formation of acyl ghrelin (AG) was recently identified. We investigated changes in circulating AG, desacyl ghrelin (DG) and GOAT induced by intraperitoneal LPS (100 mu g/kg) and associated changes in food intake. Plasma AG and total ghrelin were assessed by radioimmunoassay, GOAT protein by Western blot and mRNA by RT-OCR. DG was derived from total minus AG. Plasma AG and DG were decreased at 2,5 and 7 h (p < 0.01) post-injection compared to vehicle and recovered at 24 h. At 2 h there was a significantly greater decrease of AG (-53%) than DG (-28%) resulting in a decreased AG/DG ratio (1:5,p < 0.01), which thereafter returned to pre-injection values (1:3). This altered ratio was associated with a 38% decrease in plasma GOAT protein compared to vehicle (p < 0.001), whereas gastric GOAT protein was slightly increased by 10% (p < 0.05). GOAT mRNA expression was unchanged. Food intake was reduced by 58% measured during the 1.5-2 h period post-LPS injection. Decreased plasma AG and DG preceded the rise in rectal temperature and blood glucose that peaked at 7 h. These data indicate that LPS induces a long-lasting reduction of AG and DG levels that may have a bearing with the decrease in food intake. The faster drop in AG than DG within 2 h is associated with reduced circulating GOAT. Published by Elsevier Inc. C1 [Lambrecht, Nils W.

The theory of planned behavior posits that individuals' behaviors (using genomic services) are driven by their behavioral intentions. Behavioral intentions is a function of: first, behavioral beliefs; second, normative beliefs, and third; control beliefs. Materials & methods: Semi-structured interviews were conducted with 20 providers working in different units at the South Texas Veterans Health Care System (STVHCS; TX USA). The interviews focused on assessing providers' behavioral beliefs, normative beliefs and control beliefs regarding the delivery of genomic medicine at the STVHCS. Interview materials were tape recorded, transcribed and the content was analyzed using qualitative methods. Results: All participating providers perceived genomic medicine to be an important area in medicine (behavioral beliefs). They agreed that the VHA has the necessary infrastructure to foster the delivery of genomic services. The majority of participants (n = 18; 90%) agreed that primary care providers will play a major role in delivering genomic services. Providers indicated that referents' (other providers) opinions about genomic services may affect their decisions about whether to utilize genomic services (normative beliefs). However, most providers (n = 17; 85%) raised concerns about the impact of using genomic services on the process of care (control beliefs). Participants indicated that additional training for providers and patients, and decision support will facilitate the delivery of genomic services (control beliefs). Providers also identified three external barriers: first, uncertainty about genomic findings; second, coordination of care between primary care, specialists and genetic services (system level barriers); and third ethical issues associated with genomic information and services. Conclusion: Our findings highlight several opportunities and challenges related to the delivery of genomic medicine at the VHA. The results suggest that strategies to address providers' concerns in the control beliefs domain may be necessary to enhance providers' utilization of genomic services in clinical practice.

TI FINANCIAL CONFLICTS OF INTEREST AND THE ETHICAL OBLIGATIONS OF MEDICAL SCHOOL FACULTY AND THE PROFESSION SO PERSPECTIVES IN BIOLOGY AND MEDICINE LA English DT Article ID PHARMACEUTICAL-INDUSTRY; HIDDEN CURRICULUM; CLINICAL CARE; PHYSICIANS; EDUCATION; DOCTORS; IMPACT AB Despite their potential benefits, relationships linking medical school faculty and the pharmaceutical and device industries may also challenge the professional value of primacy of patient welfare, a point highlighted in a recent Institute of Medicine report. Academic medical centers and professors have the added professional obligation to ensure the unbiased, evidence-based education of future doctors. This essay argues that faculty financial conflicts of interest may threaten this obligation by propagating the bias introduced by these relationships to students. This could occur directly through the process of curriculum determination and delivery, and also indirectly through the "hidden curriculum," which deserves particular attention, as its lessons may conflict with those professed in the formal curriculum. The essay concludes with guiding principles to consider when developing a conflict of interest policy at academic medical centers.

Data pertinent to each of the statements were identified through review of pertinent literature by one of the 9-member panel, enabling a critical evaluation of the statements and the evidence supporting or refuting them. Three statements addressed the validity of serum growth hormone (GH) and insulin-like growth factor-I (IGF-I) concentrations as indicators or predictors of disease in acromegaly. Statements regarding the effects of preoperative somatostatin analog use on pituitary surgical outcomes, their effects on hormone and symptom control in carcinoid syndrome, and the efficacy of extended dosing intervals were reviewed. Panel opinions, based on the level of available scientific evidence, were polled. Finally, their views were compared with those of surveyed community-based endocrinologists and neurosurgeons.

TI Allelic Selection of Amplicons in Glioblastoma Revealed by Combining Somatic and Germline Analysis SO PLOS GENETICS LA English DT Article ID MYELOPROLIFERATIVE NEOPLASMS; PHASE-II; SUSCEPTIBILITY; GENE; AMPLIFICATION; EXPRESSION; INHIBITORS; EVOLUTION; VARIANTS; PATHWAYS AB Cancer is a disease driven by a combination of inherited risk alleles coupled with the acquisition of somatic mutations, including amplification and deletion of genomic DNA. Potential relationships between the inherited and somatic aspects of the disease have only rarely been examined on a genome-wide level. Applying a novel integrative analysis of SNP and copy number measurements, we queried the tumor and normal-tissue genomes of 178 glioblastoma patients from the Cancer Genome Atlas project for preferentially amplified alleles, under the hypothesis that oncogenic germline variants will be selectively amplified in the tumor environment. Selected alleles are revealed by allelic imbalance in amplification across samples. This general approach is based on genetic principles and provides a method for identifying important tumor-related alleles. We find that SNP alleles that are most significantly overrepresented in amplicons tend to occur in genes involved with regulation of kinase and transferase activity, and many of these genes are known contributors to gliomagenesis. The analysis also implicates variants in synapse genes. By incorporating gene expression data, we demonstrate synergy between preferential allelic amplification and expression in DOCK4 and EGFR. Our results support the notion that combining germline and tumor genetic data can identify regions relevant to cancer biology.

CA Int Schizophrenia Consortium TI Accurately Assessing the Risk of Schizophrenia Conferred by Rare Copy-Number Variation Affecting Genes with Brain Function SO PLOS GENETICS LA English DT Article ID GENOME-WIDE ASSOCIATION; INCREASE RISK; AUTISM; POPULATION; EXPRESSION; DELETIONS; PATHWAYS; DISORDER; DATABASE; TOOL AB Investigators have linked rare copy number variation (CNVs) to neuropsychiatric diseases, such as schizophrenia. One hypothesis is that CNV events cause disease by affecting genes with specific brain functions. Under these circumstances, we expect that CNV events in cases should impact brain-function genes more frequently than those events in controls. Previous publications have applied "pathway" analyses to genes within neuropsychiatric case CNVs to show enrichment for brain-functions. While such analyses have been suggestive, they often have not rigorously compared the rates of CNVs impacting genes with brain function in cases to controls, and therefore do not address important confounders such as the large size of brain genes and overall differences in rates and sizes of CNVs. To demonstrate the potential impact of confounders, we genotyped rare CNV events in 2,415 unaffected controls with Affymetrix 6.0; we then applied standard pathway analyses using four sets of brain-function genes and observed an apparently highly significant enrichment for each set. The enrichment is simply driven by the large size of brain-function genes. Instead, we propose a case-control statistical test, cnv-enrichment-test, to compare the rate of CNVs impacting specific gene sets in cases versus controls. With simulations, we demonstrate that cnv-enrichment-test is robust to case-control differences in CNV size, CNV rate, and systematic differences in gene size. Finally, we apply cnv-enrichment-test to rare CNV events published by the International Schizophrenia Consortium (ISC). This approach reveals nominal evidence of case-association in neuronal-activity and the learning gene sets, but not the other two examined gene sets. The neuronal-activity genes have been associated in a separate set of schizophrenia cases and controls; however, testing in independent samples is necessary to definitively confirm this association. Our method is implemented in the PLINK software package.

TI A Single cis Element Maintains Repression of the Key Developmental Regulator Gata2 SO PLOS GENETICS LA English DT Article ID TRANSCRIPTION FACTOR GATA-1; ERYTHROID-DIFFERENTIATION; CHROMATIN OCCUPANCY; HEMATOPOIETIC-CELLS; H3K4 METHYLATION; FACTOR INTERPLAY; GENE-EXPRESSION; STEM-CELLS; ERYTHROPOIESIS; GENOME AB In development, lineage-restricted transcription factors simultaneously promote differentiation while repressing alternative fates. Molecular dissection of this process has been challenging as transcription factor loci are regulated by many transacting factors functioning through dispersed cis elements. It is not understood whether these elements function collectively to confer transcriptional regulation, or individually to control specific aspects of activation or repression, such as initiation versus maintenance. Here, we have analyzed cis element regulation of the critical hematopoietic factor Gata2, which is expressed in early precursors and repressed as GATA-1 levels rise during terminal differentiation. We engineered mice lacking a single cis element -1.8 kb upstream of the Gata2 transcriptional start site. Although Gata2 is normally repressed in late-stage erythroblasts, the -1.8 kb mutation unexpectedly resulted in reactivated Gata2 transcription, blocked differentiation, and an aberrant lineage-specific gene expression pattern. Our findings demonstrate that the -1.8 kb site selectively maintains repression, confers a specific histone modification pattern and expels RNA Polymerase II from the locus. These studies reveal how an individual cis element establishes a normal developmental program via regulating specific steps in the mechanism by which a critical transcription factor is repressed.

Useful populations need high-frequency alleles to ensure high power to detect quantitative trait loci (QTLs), low linkage disequilibrium between markers to obtain accurate mapping resolution, and an absence of population structure to prevent false positive associations. We surveyed 66 colonies for inbreeding, genetic diversity, and linkage disequilibrium, and we demonstrate that some have haplotype blocks of less than 100 Kb, enabling gene-level mapping resolution. The same alleles contribute to variation in different colonies, so that when mapping progress stalls in one, another can be used in its stead. Colonies are genetically diverse: 45% of the total genetic variation is attributable to differences between colonies. However, quantitative differences in allele frequencies, rather than the existence of private alleles, are responsible for these population differences. The colonies derive from a limited pool of ancestral haplotypes resembling those found in inbred strains: over 95% of sequence variants segregating in outbred populations are found in inbred strains. Consequently it is possible to impute the sequence of any mouse from a dense SNP map combined with inbred strain sequence data, which opens up the possibility of cataloguing and testing all variants for association, a situation that has so far eluded studies in completely outbred populations. We demonstrate the colonies' potential by identifying a deletion in the promoter of H2-Ea as the molecular change that strongly contributes to setting the ratio of CD4+ and CD8+ lymphocytes.

TI The OmpL37 Surface-Exposed Protein Is Expressed by Pathogenic Leptospira during Infection and Binds Skin and Vascular Elastin SO PLOS NEGLECTED TROPICAL DISEASES LA English DT Article ID EXTRACELLULAR-MATRIX PROTEINS; OUTER-MEMBRANE PROTEINS; MONOCLONAL-ANTIBODIES; STAPHYLOCOCCUS-AUREUS; PULMONARY HEMORRHAGE; FIBRONECTIN; INTERROGANS; ADHESION; LAMININ; LIPL32 AB Pathogenic Leptospira spp. shed in the urine of reservoir hosts into freshwater can be transmitted to a susceptible host through skin abrasions or mucous membranes causing leptospirosis. The infection process involves the ability of leptospires to adhere to cell surface and extracellular matrix components, a crucial step for dissemination and colonization of host tissues. Therefore, the elucidation of novel mediators of host-pathogen interaction is important in the discovery of virulence factors involved in the pathogenesis of leptospirosis. In this study, we assess the functional roles of transmembrane outer membrane proteins OmpL36 (LIC13166), OmpL37 (LIC12263), and OmpL47 (LIC13050), which we recently identified on the leptospiral surface. We determine the capacity of these proteins to bind to host tissue components by enzyme-linked immunosorbent assay. OmpL37 binds elastin preferentially, exhibiting dose-dependent, saturating binding to human skin (K(d), 104 +/- 19 nM) and aortic elastin (K(d), 152 +/- 27 nM). It also binds fibrinogen (K(d), 244 +/- 15 nM), fibrinogen fragment D (K(d), 132 +/- 30 nM), plasma fibronectin (K(d), 359 +/- 68 nM), and murine laminin (K(d), 410 +/- 81 nM). The binding to human skin elastin by both recombinant OmpL37 and live Leptospira interrogans is specifically enhanced by rabbit antiserum for OmpL37, suggesting the involvement of OmpL37 in leptospiral binding to elastin and also the possibility that host-generated antibodies may promote rather than inhibit the adherence of leptospires to elastin-rich tissues. Further, we demonstrate that OmpL37 is recognized by acute and convalescent leptospirosis patient sera and also by Leptospira-infected hamster sera. Finally, OmpL37 protein is detected in pathogenic Leptospira serovars and not in saprophytic Leptospira. Thus, OmpL37 is a novel elastin-binding protein of pathogenic Leptospira that may be promoting attachment of Leptospira to host tissues.

TI Broad Spectrum Antiangiogenic Treatment for Ocular Neovascular Diseases SO PLOS ONE LA English DT Article ID MACULAR DEGENERATION; CHOROIDAL NEOVASCULARIZATION; CYTOKINE EXPRESSION; ACTIVATION STEPS; PHOTOTRANSDUCTION; ANGIOGENESIS; RANIBIZUMAB; RETINOPATHY; RPE; ROD AB Pathological neovascularization is a hallmark of late stage neovascular (wet) age-related macular degeneration (AMD) and the leading cause of blindness in people over the age of 50 in the western world. The treatments focus on suppression of choroidal neovascularization (CNV), while current approved therapies are limited to inhibiting vascular endothelial growth factor (VEGF) exclusively. However, this treatment does not address the underlying cause of AMD, and the loss of VEGF's neuroprotective can be a potential side effect. Therapy which targets the key processes in AMD, the pathological neovascularization, vessel leakage and inflammation could bring a major shift in the approach to disease treatment and prevention. In this study we have demonstrated the efficacy of such broad spectrum antiangiogenic therapy on mouse model of AMD. Methods and Findings: Lodamin, a polymeric formulation of TNP-470, is a potent broad-spectrum antiangiogenic drug. Lodamin significantly reduced key processes involved in AMD progression as demonstrated in mice and rats. Its suppressive effects on angiogenesis, vascular leakage and inflammation were studied in a wide array of assays including; a Matrigel, delayed-type hypersensitivity (DTH), Miles assay, laser-induced CNV and corneal micropocket assay. Lodamin significantly suppressed the secretion of various pro-inflammatory cytokines in the CNV lesion including monocyte chemotactic protein-1 (MCP-1/Ccl2). Importantly, Lodamin was found to regress established CNV lesions, unlike soluble fms-like tyrosine kinase-1 (sFlk-1). The drug was found to be safe in mice and have little toxicity as demonstrated by electroretinography (ERG) assessing retinal and by histology. Conclusions: Lodamin, a polymer formulation of TNP-470, was identified as a first in its class, broad-spectrum antiangiogenic drug that can be administered orally or locally to treat corneal and retinal neovascularization. Several unique properties make Lodamin especially beneficial for ophthalmic use. Our results support the concept that broad spectrum antiangiogenic drugs are promising agents for AMD treatment and prevention.

TI Amino-Acid Co-Variation in HIV-1 Gag Subtype C: HLA-Mediated Selection Pressure and Compensatory Dynamics SO PLOS ONE LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; T-LYMPHOCYTE ESCAPE; PROTEASE INHIBITORS; ELITE CONTROLLERS; VIRAL LOAD; ASSOCIATIONS; MUTATIONS; POLYMORPHISMS; TRANSMISSION; INFECTION AB Background: Despite high potential for HIV-1 genetic variation, the emergence of some mutations is constrained by fitness costs, and may be associated with compensatory amino acid (AA) co-variation. To characterize the interplay between Cytotoxic T Lymphocyte (CTL)-mediated pressure and HIV-1 evolutionary pathways, we investigated AA co-variation in Gag sequences obtained from 449 South African individuals chronically infected with HIV-1 subtype C. Methodology/Principal Findings: Individuals with CTL responses biased toward Gag presented lower viral loads than individuals with under-represented Gag-specific CTL responses. Using methods that account for founder effects and HLA linkage disequilibrium, we identified 35 AA sites under Human Leukocyte Antigen (HLA)-restricted CTL selection pressure and 534 AA-to-AA interactions. Analysis of two-dimensional distances between co-varying residues revealed local stabilization mechanisms since 40% of associations involved neighboring residues. Key features of our co-variation analysis included sites with a high number of co-varying partners, such as HLA-associated sites, which had on average 55% more connections than other co-varying sites. Conclusions/Significance: Clusters of co-varying AA around HLA-associated sites (especially at typically conserved sites) suggested that cooperative interactions act to preserve the local structural stability and protein function when CTL escape mutations occur. These results expose HLA-imprinted HIV-1 polymorphisms and their interlinked mutational paths in Gag that are likely due to opposite selective pressures from host CTL-mediated responses and viral fitness constraints.

Vesicular stomatitis virus (VSV), an enveloped virus with bullet-shaped virions that measure 70x200 nm, enters cells by clathrin-dependent endocytosis. We showed previously that VSV particles exceed the capacity of typical clathrin-coated vesicles and instead enter through endocytic carriers that acquire a partial clathrin coat and require local actin filament assembly to complete vesicle budding and internalization. To understand why the actin system is required for VSV uptake, we compared the internalization mechanisms of VSV and its shorter (75 nm long) defective interfering particle, DI-T. By imaging the uptake of individual particles into live cells, we found that, as with parental virions, DI-T enters via the clathrin endocytic pathway. Unlike VSV, DI-T internalization occurs through complete clathrin-coated vesicles and does not require actin polymerization. Since VSV and DI-T particles display similar surface densities of the same attachment glycoprotein, we conclude that the physical properties of the particle dictate whether a virus-containing clathrin pit engages the actin system. We suggest that the elongated shape of a VSV particle prevents full enclosure by the clathrin coat and that stalling of coat assembly triggers recruitment of the actin machinery to finish the internalization process. Since some enveloped viruses have pleomorphic particle shapes and sizes, our work suggests that they may use altered modes of endocytic uptake. More generally, our findings show the importance of cargo geometry for specifying cellular entry modes, even when the receptor recognition properties of a ligand are maintained.

CD46 protects autologous cells from complement attack by binding to complement proteins C3b and C4b and serving as a cofactor for their cleavage. Recent data show that CD46 also plays a role in mediating acquired immune responses, and in triggering autophagy. In addition to these physiologic functions, a significant number of pathogens, including select adenoviruses, measles virus, human herpes virus 6 (HHV-6), Streptococci, and Neisseria, use CD46 as a cell attachment receptor. We have determined the crystal structure of the extracellular region of CD46 in complex with the human adenovirus type 11 fiber knob. Extracellular CD46 comprises four short consensus repeats (SCR1-SCR4) that form an elongated structure resembling a hockey stick, with a long shaft and a short blade. Domains SCR1, SCR2 and SCR3 are arranged in a nearly linear fashion. Unexpectedly, however, the structure reveals a profound bend between domains SCR3 and SCR4, which has implications for the interactions with ligands as well as the orientation of the protein at the cell surface. This bend can be attributed to an insertion of five hydrophobic residues in a SCR3 surface loop. Residues in this loop have been implicated in interactions with complement, indicating that the bend participates in binding to C3b and C4b. The structure provides an accurate framework for mapping all known ligand binding sites onto the surface of CD46, thereby advancing an understanding of how CD46 acts as a receptor for pathogens and physiologic ligands of the immune system.

The disorder is often chronic, with prominent symptoms and impairment spanning into adulthood. It is often associated with co-occurring disorders, including disruptive, mood, anxiety, and substance abuse disorders. The diagnosis of ADHD is clinically established by review of symptoms and impairment. The biological underpinning of the disorder is supported by genetic, neuroimaging, neurochemistry, and neuropsychological data. All aspects of an individual's life need to be considered in the diagnosis and treatment of ADHD. Multimodal treatment includes educational, family, and individual support. Psychotherapy alone and in combination with medication is helpful for treating patients with ADHD and comorbid disorders. Pharmacotherapy, including stimulants, noradrenergic agents, alpha-agonists, and antidepressants, plays a fundamental role in the long-term management of ADHD.

TI Paying for Performance in Population Health: Lessons From Health Care Settings SO PREVENTING CHRONIC DISEASE LA English DT Article AB The appeal of pay-for-performance in health care derives from the conceptual view that paying doctors and hospitals more to deliver better care will encourage them to deliver better care. What lessons can be learned from the successes and failures of pay-for-performance in health care settings that apply to pay-for-performance in population health? We argue that pay-for-performance requires conditions that are not easily met in population health settings. Pay-for-performance has focused on narrow clinical problems whose success depends on identifiable actors with the motivation and resources to change clinical processes or outcomes. In contrast, population health has broad goals, many antecedents, and no single, identifiable fiduciary (a person who holds assets in trust for a beneficiary). Nevertheless, with careful attention, conditions for successful pay-for-performance in population health might be met.

Interest in the inter-relationship among different types of FA has resulted in new analytic approaches to FA and their role in cancer development. We evaluated the association between erythrocyte FA and prostate cancer in 127 prostate cancer patients and 183 screen negative controls. We present three approaches to the analyses of the FA and prostate cancer association; (1) individual or common groups of FA, (2) biologically meaningful FA ratios and (3) principal components analysis. Monounsaturated FA and the alpha-linolenic:eicosapentaenoic ratio were associated with reduced risk of prostate cancer. However, Factor 1, which was strongly correlated with some long chain saturated FA, was associated with an increased risk of prostate cancer. We provide an example of modeling FA and their inter-relationships on the risk of prostate cancer. Comparing three approaches suggests the importance of considering the impact of the entire fatty acid profile in disease prevention. Published by Elsevier Ltd.

It is essential for their structural characterization to achieve high-level expression in a functional state. The aim of this work was to establish stable mammalian cell lines that enable high-level heterologous production of pure receptors in a state that supports agonist-induced allosteric conformational changes. In a tetracycline-inducible stable human embryonic kidney cells (HEK293S) cell line, GABA(A) receptors containing alpha 1 and beta 3 subunits could be expressed with specific activities of 29-34 pmol/mg corresponding to 140-170 pmol/plate, the highest expression level reported so far. Comparable figures for serotonin (5-HT3A) receptors were 49-63 pmol/mg and 245-315 pmol/plate. The expression of 10 nmol of either receptor in suspension in a bioreactor required 0.3-3.0 L. Both receptor constructs had a FLAG epitope inserted at the N-terminus and could be purified in step after solubilization using ANTI-FLAG affinity chromatography with yields of 30-40%. Purified receptors were functional. Binding of the agonist [H-3]muscimol to the purified GABA(A)R was enhanced allosterically by the general anesthetic etomidate, and purified 5-hydroxytryptamine-3A receptor supported serotonin-stimulated cation flux when reconstituted into lipid vesicles.

Cognitive behavioral therapy (CBT) approaches for this disorder have emerged recently, and available evidence from open and randomized controlled trials suggests that these approaches are promising in producing significant symptom reduction. A conceptual model of how CBT may work for ADHD is reviewed along with existing efficacy studies. A preliminary comparison of effect sizes across intervention packages suggests that targeted learning and practice of specific behavioral compensatory strategies may be a critical active ingredient in CBT for adult ADHD. The article concludes with a discussion of future directions and critical questions that must be addressed in this area of clinical research.

Understanding the broad range of errors that occur in inpatient psychiatry is a critical step toward improving systems of care for a vulnerable patient population. An explorative qualitative analysis of key informant interviews identified a preliminary typology of errors and the contextual factors that precipitate them in inpatient psychiatry. The types of errors and their contextual factors fall broadly within the rubric of categories identified in medicine and surgery. However, many of the specific errors and contextual factors manifest themselves differently and are shaped by the uniqueness of the inpatient psychiatric setting and patient population. Interventions geared toward improving systems of care for psychiatric patients should draw on best practices for safety in medicine and surgery, but also be complemented with new strategies specifically tailored to the inpatient psychiatric setting.

However, the way in which the perceiver combines auditory and visual cues may itself be subject to cultural variability. Our study investigated cultural differences between Japanese and Dutch participants in the multisensory perception of emotion. A face and a voice, expressing either congruent or incongruent emotions, were presented on each trial. Participants were instructed to judge the emotion expressed in one of the two sources. The effect of to-be-ignored voice information on facial judgments was larger in Japanese than in Dutch participants, whereas the effect of to-be-ignored face information on vocal judgments was smaller in Japanese than in Dutch participants. This result indicates that Japanese people are more attuned than Dutch people to vocal processing in the multisensory perception of emotion. Our findings provide the first evidence that multisensory integration of affective information is modulated by perceivers' cultural background.

We further wished to characterize the response to D3R drugs using whole brain imaging to identify novel D3R circuitry. We investigated D3R circuitry in rats using pharmacologic MRI and challenge with selective D3R antagonists and agonist at various doses to examine regional changes in cerebral blood volume (CBV). We compared regional activation patterns with D2R/D3R agonists, as well as with prior studies of mRNA expression and autoradiography. D3R antagonists induced positive CBV changes and D3R agonist negative CBV changes in brain regions including nucleus accumbens, infralimbic cortex, thalamus, interpeduncular region, hypothalamus, and hippocampus (strongest in subiculum). All D3R-preferring drugs showed markedly greater responses in nucleus accumbens than in caudate/putamen consistent with D3R selectivity and contrary to what was observed with D2R agonists. At high doses of D3R agonist, functional changes were differentiated across cortical laminae, with layer V-VI yielding positive CBV changes and layer IV yielding negative CBV changes. These results are not inconsistent with differential D1R and D3R innervation in these layers respectively showed previously using post-mortem techniques. MRI provides a new tool for testing the in vivo selectivity of novel D3R dopaminergic ligands where radiolabels may not be available. Further, the functional D3R circuitry strongly involves hypothalamus and subiculum as well as the limbic striatum. C1 [Choi, Ji-Kyung; Mandeville, Joseph B.; Chen, Y.

Compelling theories of how smoking becomes compulsive exist but are largely based on extrapolation from neuroscience findings. Research on smokers is impeded, in part, by a lack of instruments that specifically measure compulsive smoking. This study evaluated the measurement structure and validity of the Obsessive Compulsive Smoking Scale (OCSS), a ten-item questionnaire designed to measure compulsive smoking. Participants were 239 daily smokers (a parts per thousand yen1 cigarette/day), including 142 students at a public university in Chicago and 97 veterans treated at the VA Boston Healthcare System. The OCSS and questionnaires measuring current and past smoking, cigarette craving, automatic smoking, and nicotine dependence were administered. Factor analysis with maximum likelihood extraction and oblique rotation revealed two correlated underlying factors, interpreted as "Preoccupation with Smoking" and "Compulsive Drive." The measurement structure was consistent across students and veterans, and confirmed in an independent sample of adults (n = 95). Veterans exhibited higher OCSS scores (full scale and subscales) than students. Across groups, higher OCSS scores were positively correlated with smoking intensity, craving, and nicotine dependence. OCSS full-scale and compulsive drive scores, but not smoking preoccupation scores, were inversely correlated with past month smoking reduction and minutes since last cigarette. The OCSS is a valid and reliable inventory for measuring the degree to which daily smokers are preoccupied with smoking and engage in compulsive tobacco use, and may be useful for advancing understanding of core smoking phenotypes or for tailoring cessation therapies.

Although antisaccade performance, which reflects the ability to inhibit prepotent responses, is a putative schizophrenia endophenotype, researchers have not consistently reported the expected differences between first-degree relatives and comparison groups. Schizophrenia participants (n=219) from the large Consortium on the Genetics of Schizophrenia (COGS) sample (n=1078) demonstrated significant deficits on an overlap version of the antisaccade task compared to their first-degree relatives (n=443) and community comparison subjects (CCS; n=416). Although mean antisaccade performance of first-degree relatives was intermediate between schizophrenia participants and CCS, a linear mixed-effects model adjusting for group, site, age, and gender found no significant performance differences between the first-degree relatives and CCS. However, admixture analyses showed that two components best explained the distributions in all three groups, suggesting two distinct doses of an etiological factor. Given the significant heritability of antisaccade performance, the effects of a genetic polymorphism is one possible explanation of our results.

Methods: A secondary data analysis on 453 depressed and nondepressed post-CABG patients enrolled in a randomized, controlled, effectiveness trial of telephone-delivered collaborative care for depression. Outcome measures were collected from March 2004 to September 2007 and included pain, physical function, and mood symptoms. Results: Depressed patients (baseline Patient Health Questionnaire-9 score >= 10) versus those without depression reported significantly worse pain scores on the 36-Item Short Form Health Survey Bodily Pain Scale at baseline and up to 12 months post-CABG, p < .05. Among patients with depression, those who received collaborative care reported significantly better pain scores at each time point between 2 and 12 months post-CABG versus depressed patients randomized to the usual care control group, p < .05. Regardless of intervention status, depressed participants with at least moderate pain at baseline reported significantly lower functional status (measured by the Duke Activity Status Index) at 8 and 12 months versus depressed patients with none or mild pain, p < .05. Depressed patients with at least moderate pain at baseline were also significantly less likely to show improvement of depressive symptoms throughout the course of follow-up versus depressed patients with little or no pain, p < .05. These findings controlled for age, gender, education, race, comorbid conditions, and baseline pain diagnosis. Conclusions: Depression and pain seem to influence functional recovery post-CABG. The relationship between these two conditions and 12-month outcomes should be considered by clinicians when planning treatment.

Objective: The authors attempt to identify and close gaps in the biopsychosocial model that hinder its application in certain real-life clinical situations. Method: The authors review some of the current and historical literature on the development and application of the biopsychosocial model, and argue the shortcomings of this modality in various clinical situations. Results: The authors present three dicta to guide clinicians toward relevant areas of inquiry: 1) Think neuroanatomically; 2) Think existentially; and 3) Think "dirty;" that is, understand that patients and physicians sometimes work toward different goals. Discussion: These dicta form an addendum to the biopsychosocial model, identifying and filling three specific, commonly-encountered gaps in that paradigm, which, ironically, is usually considered all-inclusive.

TI Offensive Language in the General Hospital SO PSYCHOSOMATICS LA English DT Review ID COPROLALIA AB Background: Offensive language (spoken by medical staff and by patients and their families) is often heard in the general hospital, but its manifestations and clinical implications have not been previously examined. Objective: The authors sought to facilitate an understanding of the effects and treatment of offensive utterances and their downstream consequences. Method: The authors present a sampling of clinical vignettes that illustrate a variety of examples of hospital-based events in which offensive language was used and discuss differential diagnoses and management strategies. Results: Swearing can also be used as a psychological tool in the service of helping. Swearing may provide a channel of catharsis for aggressive drives and affects that have been building in either the doctor or the patient. Discussion: Placing offensive behaviors, for example, use of profane language, in a biopsychosocial context can facilitate an understanding of the causes, effects, and treatment of these events.

Objective: The authors examined the efficacy of citalopram in preventing IFN-alpha-induced depression in HCV patients. Method: This was a randomized, controlled trial comparing citalopram with placebo in 39 HCV patients. Results: The rate of IFN-alpha-induced depression in the sample was 15.4% (6/39). Randomization to citalopram did not decrease the statistical likelihood of developing IFN-alpha-induced depression (10.5% for citalopram vs. 20.0% for placebo). Conclusion: Citalopram does not prevent depression onset; however, an empirically-supported treatment recommendation for IFN-alpha-induced depression includes monitoring depressive symptoms throughout antiviral therapy and initiating psychiatric treatment at the initial signs of depression.

Method: The authors conducted a randomized, double-blind, placebo-controlled, prophylaxis trial at an orthopedic teaching hospital, enrolling 495 elderly patients age >= 65 years, who were undergoing elective knee-or hip-replacement surgery; 400 patients received either 5 mg of orally-disintegrating olanzapine or placebo just before and after surgery. The primary efficacy outcome was the incidence of (DSM-III-R) delirium. Results: The incidence of delirium was significantly lower in the olanzapine group than in the placebo group; this held true for both knee-and hip-replacement surgery. However, delirium lasted longer and was more severe in the olanzapine group. Advanced age, a high level of medical comorbidity, an abnormal albumin level, and having knee-replacement surgery were independent risk factors for postoperative delirium (Clinicaltrials.gov Identifier: NCT000699946). Conclusion: Administration of 10 mg of oral olanzapine perioperatively, versus placebo, was associated with a significantly lower incidence of delirium. These findings suggest that olanzapine prophylaxis of postoperative delirium may be an effective strategy. (Psychosomatics 2010; 51: 409-418) C1 New England Baptist Hosp, Dept Med, Boston, MA USA.

TI Takotsubo Cardiomyopathy After Electroconvulsive Therapy SO PSYCHOSOMATICS LA English DT Article ID LEFT-VENTRICULAR DYSFUNCTION; APICAL BALLOONING SYNDROME; MYOCARDIAL-INFARCTION AB Background: Takotsubo cardiomyopathy is a novel acute cardiac syndrome characterized by transient regional systolic dysfunction of the left-ventricular apex and mid-ventricle, with hyperkinesis of the basal left ventricular segments, which has been associated with severe emotional or physical stress. Method: This is the second published case report of takotsubo cardiomyopathy occurring in the setting of electroconvulsive therapy (ECT). Results: The patient, a 52-year-old woman, experienced chest pain and discomfort shortly after ECT treatment. She was shown to have moderate left-ventricular dysfunction, with mid-cavity left-ventricular hypo-to akinesis, and hyperkinesis in the basilar region, consistent with a diagnosis of takotsubo cardiomyopathy. There was full resolution of her symptoms within 48 hours of the initial event. Discussion: This report highlights a previously undocumented complication of ECT and adds to the growing list of stressors responsible for cases of takotsubo cardiomyopathy. The prognosis is favorable, and recovery is generally complete, especially with early recognition of the syndrome and proper supportive treatment.

TI Lung Cancer Staging Essentials: The New TNM Staging System and Potential Imaging Pitfalls SO RADIOGRAPHICS LA English DT Article ID FORTHCOMING 7TH EDITION; POSITRON-EMISSION-TOMOGRAPHY; SMALL PULMONARY NODULES; GUIDELINES 2ND EDITION; BRONCHOGENIC-CARCINOMA; INTEGRATED PET/CT; PROJECT PROPOSALS; MALIGNANT-TUMORS; LYMPH-NODES; FDG-PET AB Lung cancer is the leading cause of cancer-related deaths worldwide, with a dismal 5-year survival rate of 15%. The TNM (tumor-node-metastasis) classification system for lung cancer is a vital guide for determining treatment and prognosis. Despite the importance of accuracy in lung cancer staging, however, correct staging remains a challenging task for many radiologists. The new 7th edition of the TNM classification system features a number of revisions, including subdivision of tumor categories on the basis of size, differentiation between local intrathoracic and distant metastatic disease, recategorization of malignant pleural or pericardial disease from stage III to stage IV, reclassification of separate tumor nodules in the same lung and lobe as the primary tumor from T4 to T3, and reclassification of separate tumor nodules in the same lung but not the same lobe as the primary tumor from M1 to T4. Radiologists must understand the details set forth in the TNM classification system and be familiar with the changes in the 7th edition, which attempts to better correlate disease with prognostic value and treatment strategy. By recognizing the relevant radiologic appearances of lung cancer, understanding the appropriateness of staging disease with the TNM classification system, and being familiar with potential imaging pitfalls, radiologists can make a significant contribution to treatment and outcome in patients with lung cancer.

TI Imaging in Pregnant Patients: Examination Appropriateness SO RADIOGRAPHICS LA English DT Article ID ACUTE PULMONARY-EMBOLISM; AAPM/RSNA PHYSICS TUTORIAL; LOWER-QUADRANT PAIN; ACUTE APPENDICITIS; SUSPECTED APPENDICITIS; COMPUTED-TOMOGRAPHY; HELICAL CT; PERFUSION SCINTIGRAPHY; RADIATION-EXPOSURE; ABDOMINAL-PAIN AB A recurring source of contention between clinicians and radiologists continues to be examination appropriateness when imaging pregnant patients. With the multitude of references on potential radiation risks to the fetus, radiologists tend to be cautious and hesitant about exposing the fetus to radiation. This tendency is often interpreted by referring physicians as intrusion into and delay in the care of their patients. The risk burden of radiation exposure to the fetus has to be carefully weighed against the benefits of obtaining a critical diagnosis quickly and using a single tailored imaging study. In general, there is lower than expected awareness of radiation risks to the fetus from imaging pregnant patients. Modalities that do not use ionizing radiation, such as ultrasonography and magnetic resonance imaging, should be the preferred examinations for evaluating an acute condition in a pregnant patient. However, no examination should be withheld when an important clinical diagnosis is under consideration. Exposure to ionizing radiation may be unavoidable, but there is no evidence to suggest that the risk to the fetus after a single imaging study and an interventional procedure is significant. All efforts should be made to minimize the exposure, with consideration of the risk versus benefit for a given clinical scenario.

In light of the downstream consequences of any screening test, it was critical that mammography screening be challenged. There have been many legitimate challenges, as well as many challenges that are not scientifically based but have gained credibility because of repetition. The latter have led to a great deal of confusion among women and their physicians. The aim of this review is to dispel many of the misunderstandings that have developed in the past 4 decades and, hopefully, reduce the confusion that has occurred. Mammography screening does not find all breast cancers and does not find all cancers early enough to result in a cure, but it is a major advance, and women should not be denied access to its benefits.

Materials and Methods: A decision-analytic Markov model was developed to estimate life expectancy and lifetime costs for patients with small (<= 4-cm) renal tumors. Two strategies were compared: renal mass biopsy to triage patients to surgery or imaging surveillance and empiric nephron-sparing surgery. The model incorporated biopsy performance, the probability of track seeding with malignant cells, the prevalence and growth of benign and malignant tumors, treatment effectiveness and costs, and patient outcomes. An incremental cost-effectiveness analysis was performed to identify strategy preference under a willingness-to-pay threshold of $75 000 per quality-adjusted life-year (QALY). Effects of changes in key parameters on strategy preference were evaluated in sensitivity analysis. Results: Under base-case assumptions, the biopsy strategy yielded a minimally greater quality-adjusted life expectancy (4 days) than did empiric surgery at a lower lifetime cost ($3466), dominating surgery from a cost-effectiveness perspective. Over the majority of parameter ranges tested in one-way sensitivity analysis, the biopsy strategy dominated surgery or was cost-effective relative to surgery based on a $75 000-per-QALY willingness-to-pay threshold. In two-way sensitivity analysis, surgery yielded greater life expectancy when the prevalence of malignancy and propensity for biopsy-negative cancers to metastasize were both higher than expected or when the sensitivity and specificity of biopsy were both lower than expected. Conclusion: The use of biopsy to guide treatment decisions for small incidentally detected renal tumors is cost-effective and can prevent unnecessary surgery in many cases.

Wide varieties of portable monitors are commercially available and they range from single-channel recorders to units that record a full polysomnogram. Recent comparative effectiveness research studies have shown that clinical outcomes of patients with a high pretest probability for obstructive sleep apnea who receive ambulatory management using portable-monitor testing have similar functional outcomes and adherence to continuous positive airway pressure treatment, compared to patients managed with in-laboratory polysomnography. The cost-effectiveness of portable-monitor testing and its potential to improve patient access to diagnosis and treatment requires further investigation.

TI Modality-specific attention and multisensory integration of emotions in schizophrenia: Reduced regulatory effects SO SCHIZOPHRENIA RESEARCH LA English DT Article DE Emotion recognition; Multisensory integration; Selective attention; Modality-specific attention; Cognition; Schizophrenia ID FACIAL EXPRESSIONS; AUDIOVISUAL INTEGRATION; NEUROCOGNITIVE DEFICITS; FUNCTIONAL-SIGNIFICANCE; SELECTIVE ATTENTION; CROSSMODAL BINDING; SPEECH-PERCEPTION; SOCIAL COGNITION; HUMAN BRAIN; RECOGNITION AB Background: Deficits in emotion perception are a well-established phenomenon in schizophrenic patients and studies have typically used unimodal emotion tasks, presenting either emotional faces or emotional vocalizations. We introduced bimodal emotion conditions in two previous studies in order to study the process of multisensory integration of visible and audible emotion cues. We now build on our earlier work and address the regulatory effects of selective attention mechanisms on the ability to integrate emotion cues stemming from multisensory channels. Methods: We added a neutral secondary distractor condition to the original bimodal paradigm in order to investigate modality-specific selective attention mechanisms. We compared schizophrenic patients (n=50) to non-schizophrenic psychotic patients (n=46), as well as to healthy controls (n=50). A trained psychiatrist used the Schedules of Clinical Assessment in Neuropsychiatry (SCAN 2.1) to diagnose the patients. Results: As expected, in healthy controls, and to a lesser extent in non-schizophrenic psychotic patients, modality-specific attention attenuated multisensory integration of emotional faces and vocalizations. Conversely, in schizophrenic patients, auditory and visual distractor conditions yielded unaffected and even exaggerated multisensory integration. Conclusions: These results suggest that schizophrenics, as compared to healthy controls and non-schizophrenic psychotic patients, have modality-specific attention deficits when attempting to integrate information regarding emotions that stem from multichannel sources. Various explanations for our findings, as well as their possible consequences, are discussed. (C) 2010 Elsevier B.V. All rights reserved.

TI Case-control study of the relationship of depressive symptoms to suicide in a community-based sample of individuals with schizophrenia in China SO SCHIZOPHRENIA RESEARCH LA English DT Article DE Depression; Suicide; Schizophrenia; China; Psychological autopsy ID PSYCHOLOGICAL AUTOPSY; RISK-FACTORS; MENTAL-DISORDERS; RURAL-COMMUNITY; MAINLAND CHINA; PREVENTION; MORTALITY; TRIAL; MOOD AB Background: Suicide is the leading cause of premature death among people with schizophrenia. Most studies on suicide and schizophrenia report an associated depression history, but they are based on clinical samples from mostly western countries. Methods: We conducted a secondary analysis of 74 suicides (cases) and 24 accidental deaths (controls) among persons with schizophrenia identified in a national psychological autopsy study in mainland China using the Chinese version of the Structured Clinical Interview for DSM-IV. A 'depression symptom severity score' based on number, severity, and persistence of depressive symptoms 2 weeks before death was derived from psychiatric interviews with 2 informants; determination of a 'dysfunction due to depressive symptoms score' was based on informants' reports about effects of depressive symptoms on decedents' functioning in the month before death. In addition, the mean number of negative life events was determined along with the effect of the events on the decedent. Comparison of the measures made for cases and controls were made by univariate analysis followed by adjustments using the False Discovery Rate. Results: Compared to persons with schizophrenia who died by accident, those who died by suicide were more likely to have a recent DSM IV diagnosis of major depression, the symptom of depressed mood, thoughts of death and a prior suicide attempt. In addition, those who died by suicide were more likely to have a higher overall depression severity score and greater dysfunction due to depressive symptoms. Discussion: This community-based study of individuals with DSM-IV schizophrenia who died by suicide in a non-western culture extends findings from clinical studies in western cultures providing data on the importance of depressive symptoms as risk factors for suicide in schizophrenia in a low income rural setting. These findings underline the importance of routine screening for depressive symptoms among patients with schizophrenia. Published by Elsevier B.V.

Since niacin-induced skin flushing is mediated by vasodilators derived from arachidonic acid (AA), we tested whether the blunted flush response to niacin is a marker of AA deficiency. Methods: Eight concentrations of methylnicotinate were applied to the forearms of 20 adults with schizophrenia and 20 controls. Laser Doppler measurement of blood flow responses was used to derive values for niacin sensitivity (defined as the concentration eliciting half-maximal response, i.e., EC(50) value) and efficacy (defined as the maximal evoked blood flow response). RBC membrane fatty acids were analyzed by gas chromatography. Results: Niacin sensitivity and efficacy were reduced in schizophrenia. In the control group, there was significant correlation between AA levels and niacin sensitivity as well as a trend toward correlation between AA levels and niacin efficacy. In contrast, neither sensitivity nor efficacy of niacin correlated with AA levels in schizophrenia. An expected correlation between the levels of AA and its elongation product (adrenic acid) was absent in schizophrenia. Adrenic acid levels correlated with niacin efficacy in schizophrenia. Conclusions: The schizophrenia-associated niacin response abnormality involves both diminished sensitivity and reduced efficacy. The lack of expected correlation between levels of AA and adrenic acid suggests homeostatic imbalance within the n-6 polyunsaturated fatty acid (PUFA) pathway in schizophrenia. Though AA levels were unrelated to measures of niacin response in schizophrenia, the correlation between adrenic acid and niacin efficacy in schizophrenia suggests relevance of the n-6 PUFA pathway to the blunted niacin response.

TI Whether and When to Refer Patients for Predialysis AV Fistula Creation: Complex Decision Making in the Face of Uncertainty SO SEMINARS IN DIALYSIS LA English DT Editorial Material ID CHRONIC KIDNEY-DISEASE; VASCULAR ACCESS SURGERY; ARTERIOVENOUS-FISTULAS; HEMODIALYSIS-PATIENTS; RENAL-FAILURE; UNITED-STATES; MORTALITY; DIALYSIS; OUTCOMES; AGE AB Patients who initiate chronic dialysis with a functional arteriovenous (AV) fistula survive longer and experience fewer complications after initiation of dialysis than those who require a catheter. However, more than 80% of patients in this country begin chronic dialysis with a catheter rather than a fistula, either because they do not have a permanent access or their permanent access is not ready for use. Increasing rates of predialysis AV fistula placement is thus considered a priority area for predialysis care in this country. However, achievement of a functional AV fistula by the time of dialysis initiation is not always an easy proposition. We here outline the limitations of currently recommended approaches toward timing of AV fistula placement. We also highlight the potential complexity of patient and clinician decision making in this area. Particularly in the presence of advanced age and a high burden of comorbidity and disability, it is often uncertain whether patients will need, want, or benefit from chronic dialysis. Adding to this uncertainty, it is often not known whether, when, and after how many revisions an AV fistula will be sufficiently mature to support dialysis. We argue that it is important to acknowledge the complexity of medical decision making in this area and the limitations of currently available prognostic tools to guide such decision making. We conclude that initiation of dialysis with a catheter is appropriate for patients in whom the perceived harms of preemptive fistula placement outweigh the expected benefit.

Methods: Review of select recent literature on in vivo confocal microscopy and atypical microbial keratitis. Results: Delayed diagnosis of Acanthamoeba and fungal keratitis is typical, resulting in significant vision loss. This is partially due to the low sensitivity and time delay of corneal cultures. In the hands of an experienced viewer, the confocal microscope has been found to have a sensitivity of up to 90% in the diagnosis of Acanthamoeba keratitis and close to 80% for fungal keratitis. Conclusion: In vivo confocal microscopy is emerging as a tool for rapid diagnoses in severe infectious keratitis with high sensitivity. In addition, it can be used to monitor treatment response, allowing guidance to clinicians for medical or surgical management.

In vivo confocal microscopy (IVCM) has an enormous potential, being a noninvasive procedure that images the living cornea, to study both its physiological and pathological states. Corneal nerves are of great interest to clinicians and scientists due to their important roles in regulating corneal sensation, epithelial integrity, proliferation, wound healing, and for their protective functions. IVCM enables the noninvasive examination of corneal nerves, allowing the study of nerve alterations in different ocular diseases, after corneal surgery, and in systemic diseases. To date, the correlation of sub-basal corneal nerves and their function has been studied in normal eyes, keratoconus, dry eye, contact lens wearers, and in neurotrophic keratopathy, among others. Further, the effect of corneal surgery on nerves has been studied, demonstrating the regenerative capacity of corneal nerves and the recovery of sensation. Moreover, IVCM has been applied in the diagnosis of peripheral diabetic neuropathy and the assessment of progression in this systemic disease. The purpose of this review is to describe the principles, applications, and clinical correlation of IVCM in the study of corneal nerves in different ocular and systemic diseases.

The human eye is fraught with higher order of aberrations. Since we are forced to use the human optical system in retinal imaging, the images are degraded. In addition, all of these distortions are constantly changing due to head/eye movement and change in accommodation. Adaptive optics is a promising technology introduced in the field of ophthalmology to measure and compensate for these aberrations. High-resolution obtained by adaptive optics enables us to view and image the retinal photoreceptors, retina pigment epithelium, and identification of cone subclasses in vivo. In this review we will be discussing the basic technology of adaptive optics and hardware requirement in addition to clinical applications of such technology.

OCT imaging has rapidly been integrated into diagnosis and management of diabetic macular edema (DME) in routine clinical practice and clinical trials. OCT findings correlate well with other evaluation techniques for DME. Although there is a moderate correlation between OCT measured retinal thickness and visual acuity, OCT cannot replace visual acuity because there is a high degree of variability. Recent improvements in OCT technology have led to widespread interest in the use of spectral domain OCT, which is faster and has higher resolution than time domain OCT. Future research in OCT imaging will likely result in improvements in image quality. The ability to combine OCT with other various diagnostic modalities will further improve the evaluation of DME in both clinical practice and trials. C1 [Al-Latayfeh, M. M.; Sun, J.

Optical coherence tomography (OCT) has begun to be utilized as an adjunctive, quantitative tool in the evaluation of patients with IIH to help distinguish between true optic nerve head edema and pseudopapilledema, and to contribute to our understanding of the consequences of prolonged optic nerve edema. Although few longitudinal studies of patients with IIH have been published to date, it appears that there may be a correlation between retinal nerve fiber layer (RNFL) thickness and visual function. With the new spectral domain OCT, additional parameters of the optic nerve imaging, including volume and height measurements, might provide greater sensitivity of the response to treatment and the long-term visual outcome in patients with IIH.

Methods: A review and analysis of the keratoprosthesis literature specifically examining design modifications, treatment of post operative complications, and patient selection was performed. Results: Over the past two decades, many modifications to the design of the Boston type I keratoprosthesis and treatment of the patient in the post operative period have occurred. Also, the technology has been more widely accepted as a primary surgical option for patients with a poor preoperative prognosis for traditional penetrating keratoplasty. The outcomes of visual acuity, retention, and post-operative infection rates have all significantly improved since the technology has been modified and offers patients an alternative for visual rehabilitation. Conclusions: Thanks to advances in design and perioperative care, the boston type i keratoprosthesis can now be considered a viable option for surgical visual rehabilitation in many patients with corneal pathology, and in certain groups the primary surgical procedure of choice.

There are 4 major devices available: the Molteno, Baerveldt, Krupin, and Ahmed. The Molteno and Baerveldt are non-valved implants, while the Krupin and Ahmed are valved. The success rates of the different valves are about equal at approximately 70% with a mean intraocular pressure (IOP) lowering of at least 50% from the pre-operative IOP. Unfortunately, the failure rate is about 10% per year, leading to only 50% functional drainage devices at 5 years. Therefore, research on the biomaterials, shape, and technique of drainage implant surgery is being done in hopes of increasing long term success rates.

Methods: We performed an extensive review of the current literature. We included only large comparative institutional reviews. Meta-analysis of these reviews was performed. Results: We found six large retrospective comparative cases series on the 25-gauge (25G) TSV as compared to 20G PPV. The test for homogeneity for the meta-analysis indicates that the studies are not homogeneous and therefore the evidence is tentative. Conclusion: We cannot conclude that 25G TSV has a higher rate of postoperative endophthalmitis compared to the 20G PPV. Future retrospective or prospective trials need to take into consideration multiple factors.

While corticosteroids are a mainstay of therapy for uveitis and macular edema, the methods of delivering corticosteroids have evolved. Intravitreal triamcinolone acetonide provides a local therapy for persistent cystoid macular edema (CME) and posterior uveitis. Other intravitreal therapies, such as bevacizumab and methotrexate, have also been used successfully in uveitic CME. Sustained release intravitreal implants, including the fluocinolone acetonide implant and the dexamethasone drug delivery system, offer an alternative therapy for chronic, recalcitrant posterior uveitis and CME. Their design was inspired by the ganciclovir implant, which prevented the progression of CMV retinitis in AIDS patients. Technological advances in drug delivery have supplied new treatments for patients with ocular inflammatory disease.

In many instances it can be addressed with pars plana vitrectomy, although this approach, like any surgery, has its limitations. The search for alternatives or adjunct to surgery has led to the development of pharmacologic vitreolysis. The use of intravitreal agents to alter the vitreous in order to reduce or eliminate its role in disease seems promising. The purpose of this article is to summarize the present knowledge on pharmacologic vitreolysis. A review of the different agents used and of ongoing trials will be presented.

Visual field testing in the form of automated perimetry is critical in the clinical diagnosis and monitoring of glaucoma. Functional tests can also be powerful research tools in clinical trials and in the field of neuroprotection. Standard automated perimetry (SAP) commonly used today, however, has its limitations. Early diagnosis of glaucoma based on functional measures can be challenging since it has been shown that retinal ganglion cell loss precedes defects detected on SAP. In addition, SAP is a subjective test prone to inter-test variability making the evaluation of disease progression problematic. Newer algorithms and functional tests are now being used and developed in an attempt to improve the accuracy in the detection of glaucoma and disease progression.

Because there are several common sources of sleep problems in midlife women, the cause of an individual woman's sleep disturbance may be multifactorial. Effective behavioral and pharmacological therapies are available to treat sleep disturbances of different etiologies. This review provides an overview of different types of sleep disturbance occurring in midlife women and presents data supporting the use of hormone therapy, hypnotic agents, and behavioral strategies to treat sleep problems in this population. The review aims to equip clinicians evaluating menopause-age women with the knowledge and evaluation tools to diagnose, engage sleep experts where appropriate, and treat sleep disturbance in this population. Sleep disorders in midlife women should be treated because substantial improvements in quality of life and health outcomes are achievable.

Clinical neuropsychology is an area of psychology that specializes in the diagnostic assessment and treatment of patients with brain injury or neurocognitive deficit. Specific neuropsychological correlates of sexuality have been researched in the past, including sex differences in cognitive abilities and sexual orientation. Although some consistent differences between sex and sexual orientation have been found, the majority of these differences appear to be due to an interaction of biological predisposition and sociological factors. Additionally, neuropathological correlates of sexual disorders have been found and future research into the neuropsychological correlates of sexual offenders (i.e., rapists, child molesters) is warranted. Although neuropsychology has been peripherally involved in research concerning human sexuality, there is a more prominent role for clinical neuropsychologists who are uniquely trained to provide assistance in the diagnosis and treatment of sexual deviance and sexual dysfunction/disability.

However, the role of NO synthase 3 (NOS3) during sepsis remains incompletely understood. Here, we examined the impact of NOS3 deficiency on systemic inflammation and myocardial dysfunction during peritonitis-induced polymicrobial sepsis. Severe polymicrobial sepsis was induced by colon ascendens stent peritonitis (CASP) in wild-type (WT) and NOS3-deficient (NOS3KO) mice. NOS3KO mice exhibited shorter survival time than did WT mice after CASP. NOS3 deficiency worsened systemic inflammation assessed by the expression of inflammatory cytokines in the lung, liver, and heart. Colon ascendens stent peritonitis markedly increased the number of leukocyte infiltrating the liver and heart in NOS3KO but not in WT mice. The exaggerated systemic inflammation in septic NOS3KO mice was associated with more marked myocardial dysfunction than in WT mice 22 h after CASP. The detrimental effects of NOS3 deficiency on myocardial function after CASP seem to be caused by impaired Ca(2+) handling of cardiomyocytes. The impaired Ca(2+) handling of cardiomyocytes isolated from NOS3KO mice subjected to CASP was associated with depressed mitochondrial ATP production, a determinant of the Ca(2+) cycling capacity of sarcoplasmic reticulum Ca(2+)-ATPase. The NOS3 deficiency-induced impairment of the ability of mitochondria to produce ATP after CASP was at least in part attributable to reduction in mitochondrial respiratory chain complex I activity. These observations suggest that NOS3 protects against systemic inflammation and myocardial dysfunction after peritonitis-induced polymicrobial sepsis in mice.

Using secondary analysis of transcripts from face-to-face interviews with 33 terminally-ill patients from an outpatient clinic at a public hospital serving the disadvantaged in the southern United States, we examine the legacy participants wish to leave behind. As part of this process, participants assess life circumstances to try and generate a legacy allowing them to remain personally relevant to loved ones after death. For the low-SES terminally ill persons in this study, the desire to leave a material legacy and the means to do so are not congruous. In the absence of economic resources to bequeath loved ones, participants describe their desire to leave loved ones some form of ethical currency to facilitate interactions with others and protect them against social marginalisation. We call this concept ethical capital. We then argue ethical capital is a way for disadvantaged people to find dignity and to affirm their lives.

A biomechanical study using human lumbar spines. Objective. To test the hypotheses that with increasing implant height (1) the range of motion (ROM) of the implanted segment will decrease, (2) the segmental lordosis will increase, and (3) the size of the neural foramens will increase. Summary of Background Data. Little is known about the effects of the implant height on the segmental motion and foraminal size at the implanted level. Methods. Seven human lumbar spines (age, 54.4 +/- 11.4 years; L1-sacrum) were tested intact, and after discectomy at L4-L5 and sequential insertion of ProDisc-L implants (Synthes Spine, Paoli, PA) of increasing heights (10, 12, and 14 mm). The specimens were tested in flexion (8 Nm) and extension (+/- 6 Nm) with a 400 N follower preload as well as in lateral bending (+/- 6 Nm) and axial rotation (+/- 5 Nm) without preload. Three-dimensional motions were measured at L4-L5. Foraminal sizes at L4-L5 were measured in the specimen's neutral posture under a 400 N preload for the intact spine and after each implantation using finely graded cylindrical probes. Segmental lordosis was measured in the specimen's neutral posture under a 400 N preload by analyzing digital fluoroscopic images. Effects of implant height on the kinematics, foraminal size, and segmental lordosis were assessed using paired comparisons with Bonferroni correction. Results. Increasing implant height from 10 mm to 14 mm caused a significant decrease (P < 0.05) in segmental ROM by up to 37% +/- 21% in flexion/extension, 33% +/- 18% in lateral bending, and 29% +/- 28% in axial rotation. Increasing implant height also produced a significant increase in segmental lordosis (P < 0.05): from 9.7 degrees +/- 2.9 degrees at 10 mm, to 16.1 degrees +/- 5.1 degrees at 14 mm. The increase in foraminal size, while significant, was only 4.6% +/- 3.2% when comparing 10 mm to 14 mm implants. Conclusion. These results suggest that a smaller implant height should be selected to optimize the ROM of the implanted segment and maintain sagittal balance.

Certain factors, including diabetes and history of keloid formation, predispose patients to the development of postoperative arthrofibrosis. Etiologies include rotator cuff repair, labral repair, capsulorrhaphy, shoulder arthroplasty, and proximal humerus fracture fixation. Systematic evaluation with thorough history and physical examination is essential to determine the proper treatment and to counsel patients on expectations for recovery. Nonoperative treatment focused on physical therapy is the first step in management. Manipulation under anesthesia may be an effective treatment for failure of physical therapy regimens in idiopathic adhesive capsulitis, however it is less successful in cases of postsurgical adhesions. In cases of postoperative stiffness, treatment options include arthroscopic and open capsular releases. Adequate postoperative pain control and adherence to a rigorous physical therapy regimen are integral to the success of surgical release. Surgical treatment is effective in the majority of patients with postsurgical arthrofibrosis. C1 [Vezeridis, Peter S.; Goel, Danny P.; Shah, Anup A.; Sung, Seung-Yong; Warner, Jon J.

They are thought to enter a state of relative quiescence, known as reversible cell cycle arrest, but the underlying molecular mechanisms remain poorly characterized. Previous data from our laboratory has shown that housekeeping gene expression is downregulated in melanocyte stem cells (MelSCs), suggesting a global suppression of mRNA transcription. We now show, using antibodies against specific phosphorylated forms of RNA polymerase II (RNApII), that adult MelSCs do not undergo productive mRNA transcription elongation, while RNApII is activated and initialized, ready to synthesize mRNA upon stimulation, and that the RNApII kinase CDK9 is absent in adult MelSCs. Interestingly, other adult stem cells also, including keratinocyte, muscle, spermatogonia, and hematopoietic stem cells, showed a similar absence of RNApII phosphorylation. Although it is difficult to show the functional significance of this observation in vivo, CDK9 inhibition resulted in enhanced survival of cells that are deprived from survival factors. We conclude that the absence of productive mRNA transcription is an early, specific, and conserved characteristic of adult stem cells. Downregulation of mRNA transcription may lead to decreased rates of metabolism, and protection from cellular and genetic damage. Screening heterogeneous tissues, including tumors, for transcriptionally quiescent cells may result in the identification of cells with stem cell-like phenotypes.

TI Addition of Brain Infarction to the ABCD(2) Score (ABCD(2)I) A Collaborative Analysis of Unpublished Data on 4574 Patients SO STROKE LA English DT Article DE ABCD(2) score; ABCD(2)I score; infarction; prediction; risk; TIA ID TRANSIENT ISCHEMIC ATTACK; EARLY STROKE RISK; TIA PATIENTS; METAANALYSIS; VALIDATION; PREDICT; LESIONS AB Background and Purpose-The ABCD system was developed to predict early stroke risk after transient ischemic attack. Incorporation of brain imaging findings has been suggested, but reports have used inconsistent methods and been underpowered. We therefore performed an international, multicenter collaborative study of the prognostic performance of the ABCD(2) score and brain infarction on imaging to determine the optimal weighting of infarction in the score (ABCD(2)I). Methods-Twelve centers provided unpublished data on ABCD(2) scores, presence of brain infarction on either diffusion-weighted imaging or CT, and follow-up in cohorts of patients with transient ischemic attack diagnosed by World Health Organization criteria. Optimal weighting of infarction in the ABCD(2)I score was determined using area under the receiver operating characteristic curve analyses and random effects meta-analysis. Results-Among 4574 patients with TIA, acute infarction was present in 884 (27.6%) of 3206 imaged with diffusion-weighted imaging and new or old infarction was present in 327 (23.9%) of 1368 imaged with CT. ABCD(2) score and presence of infarction on diffusion-weighted imaging or CT were both independently predictive of stroke (n=145) at 7 days (after adjustment for ABCD(2) score, OR for infarction=6.2, 95% CI=4.2 to 9.0, overall; 14.9, 7.4 to 30.2, for diffusion-weighted imaging; 4.2, 2.6 to 6.9, for CT; all P<0.001). Incorporation of infarction in the ABCD(2)I score improved predictive power with an optimal weighting of 3 points for infarction on CT or diffusion-weighted imaging. Pooled areas under the curve increased from 0.66 (0.53 to 0.78) for the ABCD(2) score to 0.78 (0.72 to 0.85) for the ABCD(2)I score. Conclusions-In secondary care, incorporation of brain infarction into the ABCD system (ABCD(2)I score) improves prediction of stroke in the acute phase after transient ischemic attack.

TI MRI Markers of Small Vessel Disease in Lobar and Deep Hemispheric Intracerebral Hemorrhage SO STROKE LA English DT Article DE cerebral amyloid angiopathy; intracerebral hemorrhage; leukoaraiosis; MRI; white matter disease ID CEREBRAL AMYLOID ANGIOPATHY; WHITE-MATTER LESIONS; ALZHEIMER-DISEASE; MICROBLEEDS; BRAIN; HYPERINTENSITIES; HYPERTENSION; VALIDATION; COGNITION; DEMENTIA AB Background and Purpose-MRI evidence of small vessel disease is common in intracerebral hemorrhage (ICH). We hypothesized that ICH caused by cerebral amyloid angiopathy (CAA) or hypertensive vasculopathy would have different distributions of MRI T2 white matter hyperintensity (WMH) and microbleeds. Methods-Data were analyzed from 133 consecutive patients with primary supratentorial ICH and adequate MRI sequences. CAA was diagnosed using the Boston criteria. WMH segmentation was performed using a validated semiautomated method. WMH and microbleeds were compared according to site of symptomatic hematoma origin (lobar versus deep) or by pattern of hemorrhages, including both hematomas and microbleeds, on MRI gradient recalled echo sequence (grouped as lobar only-probable CAA, lobar only-possible CAA, deep hemispheric only, or mixed lobar and deep hemorrhages). Results-Patients with lobar and deep hemispheric hematoma had similar median normalized WMH volumes (19.5 cm versus 19.9 cm(3), P=0.74) and prevalence of >= 1 microbleed (54% versus 52%, P=0.99). The supratentorial WMH distribution was similar according to hemorrhage location category; however, the prevalence of brain stem T2 hyperintensity was lower in lobar hematoma versus deep hematoma (54% versus 70%, P=0.004). Mixed ICH was common (23%). Patients with mixed ICH had large normalized WMH volumes and a posterior distribution of cortical hemorrhages similar to that seen in CAA. Conclusions-WMH distribution is largely similar between CAA-related and non-CAA-related ICH. Mixed lobar and deep hemorrhages are seen on MRI gradient recalled echo sequence in up to one fourth of patients; in these patients, both hypertension and CAA may be contributing to the burden of WMH.

TI High-Mobility Group Box 1 Promotes Metalloproteinase-9 Upregulation Through Toll-Like Receptor 4 After Cerebral Ischemia SO STROKE LA English DT Article DE cerebral ischemia; matrix metalloproteinase; high-mobility group box 1 ID CENTRAL-NERVOUS-SYSTEM; BLOOD-BRAIN-BARRIER; EXPERIMENTAL STROKE; PROTEIN; CYTOKINE; HMGB1; MATRIX-METALLOPROTEINASE-9; NEUROINFLAMMATION; EXPRESSION; RESPONSES AB Background and Purpose-HMGB1 is a nuclear protein and an alarmin that signals cell damage in response to injury. It is believed that after release from injured cells, HMGB1 binds to its receptors to stimulate cross-talk among cells and to drive components of the inflammatory cascade. This study was intended to investigate the role of extracellular HMGB1 in ischemic stroke by examining the response of the zymogen matrix metalloproteinase-9 (MMP-9) to HMGB1 in vivo and in vitro. Methods-Toll-like receptor 2 (TLR2), TLR4, receptor for advanced glycation endproducts (RAGE), and MMP-9 expression was examined using quantitative RT-PCR in primary cultured neurons, astrocytes, and mouse brain after HMGB1 addition. MMP-9 expression/activity was examined using zymography. Middle cerebral artery occlusion was induced for 60 minutes using a filament model. Results-TLR4 is constitutively expressed in neurons, astrocytes, and mouse brain. HMGB1 addition to neuronal and glial cell cultures caused MMP-9 upregulation in a dose-and time-dependent manner. Lack of TLR4 function attenuated MMP-9 expression induced by HMGB1 in vitro. After striatal microinjection of HMGB1, MMP-9 was upregulated, and the response was independent of tumor necrosis factor-alpha. Interestingly, MMP-9 upregulation was reduced in TLR4 missense mutant mice after ischemia compared with wild-type controls, as was infarct volume. Conclusion-Our results suggest that HMGB1 triggers MMP-9 upregulation in neurons and astrocytes predominantly via TLR4 after cerebral ischemia. Hence, targeting HMGB1/TLRs signaling pathway may reduce the acute inflammatory response and reduce tissue damage in cerebral ischemia. (Stroke. 2010;41:2077-2082.)

CA Guidelines-Stroke Steering Comm TI Rapid Change in Prescribing Behavior in Hospitals Participating in Get With The Guidelines-Stroke After Release of the Management of Atherothrombosis With Clopidogrel in High-Risk Patients (MATCH) Clinical Trial Results SO STROKE LA English DT Article DE antiplatelet drugs; antithrombotics; health services research; ischemic stroke; quality of care ID TRANSIENT ISCHEMIC ATTACK; ANTIPLATELET THERAPY; ASPIRIN; TRENDS AB Background and Purpose-Physician prescribing patterns change slowly despite published randomized trials and consensus guidelines. We measure the effect of Management of Atherothrombosis With Clopidogrel in High-Risk Patients (MATCH) trial on discharge prescribing patterns for patients with stroke and those with transient ischemic attack in the Get With The Guidelines (GWTG)-Stroke Program. Methods-We analyzed discharge prescribing patterns of antithrombotic medications for patients admitted with ischemic stroke or transient ischemic attack at hospitals participating in GWTG-Stroke between October 2002 to January 2006. Clinical information by quarter was analyzed in relation to publication of the MATCH study. Frequency of discharge prescription of aspirin+clopidogrel post-MATCH publication was compared with the pre-MATCH period after adjusting for patient and hospital characteristics and clustering by hospital. Results-A total of 107 872 patients at 632 sites were eligible to receive antithrombotic therapy at discharge. Use of aspirin+clopidogrel therapy declined from 22.4% to 15.4% of patients after the publication of MATCH (adjusted OR 0.62, 95% CI 0.56 to 0.70, P<0.0001). Analysis by quarter revealed a rapid and sustained decrease in use of aspirin+clopidogrel therapy for the remainder of the study period. Conclusions-A rapid and sustained reduction in the frequency of aspirin+clopidogrel use in ischemic stroke and transient ischemic attack was observed after publication of the MATCH trial in the absence of MATCH-specific GWTG-Stroke initiatives and preceding an American Heart Association guideline update.

TI The intraoperative Surgical Apgar Score predicts postdischarge complications after colon and rectal resection SO SURGERY LA English DT Article; Proceedings Paper CT Annual Meeting of the American-Society-of-Colon-and-Rectal-Surgeons CY MAY 02-06, 2009 CL Hollywood, FL SP Amer Soc Colon & Rectal Surg ID QUALITY IMPROVEMENT PROGRAM; HOME-BASED INTERVENTION; HOSPITAL READMISSION; MYOCARDIAL-INFARCTION; INTESTINAL SURGERY; NONCARDIAC SURGERY; HEMODYNAMIC PREDICTORS; UNPLANNED READMISSIONS; COLORECTAL SURGERY; MORTALITY AB Background. We previously developed an intraoperative 10-point Surgical Apgar Score-based on blood loss, lowest heart rate, and lowest mean arterial pressure-to predict major complications after colorectal resection. However, because complications often arise after uncomplicated hospitalizations, we sought to evaluate whether this intraoperative metric would predict postdischarge complications after colectomy. Methods. We linked our institution's National Surgical Quality Improvement Program database with an Anesthesia Intraoperative Management System for all colorectal resections over 4 years. Using Chi-square trend tests and logistic regression, we evaluated the Surgical Apgar Score's prediction for major postoperative complications before and after discharge. Results. Among 795 colectomies, there were 230 (29%) major complications within 30 days; 45 (20%) after uncomplicated discharges. Surgical Apgar Scores predicted both inpatient complications and late postdischarge complications (both P < .0001). Late complications occurred from 0 to 27 (median, 11) days after discharge; the most common were surgical site infections (42%), sepsis (24%), and venous thromboembolism (16%). In pair-wise comparisons against average-scoring patients (Surgical Apgar Scores, 7-8), the relative risk of postdischarge complications trended lower, to 0.6 (95% confidence interval [CI], 0.2-1.7) for those with the best scores (9-10); and were significantly higher, at 2.6 (95% CI, 1.4-4.9) for scores 5-6, and 4.5 (95% CI, 1.8-11.0) for scores 0-4. Conclusion. The intraoperative Surgical Apgar Score remained a useful metric for predicting postcolectomy complications arising after uncomplicated discharges. Even late complications may thus be related to intraoperative condition and events. Surgeons could use this intraoperative metric to target low-scoring patients for intensive postdischarge surveillance and mitigation of postdischarge complications after colectomy.

WG involves many interrelated pathogenic pathways that are genetic, cell-mediated, neutrophil-mediated, humoral, and environmental. WG most commonly involves the upper respiratory tract, lungs, and kidneys, but has been reported to affect almost any organ. Ophthalmologic involvement is an important cause of morbidity in WC patients, occurring in approximately one-half of patients. The presence of unexplained orbital inflammatory disease, scleritis, peripheral ulcerative keratitis, cicatricial conjunctivitis, nasolacrimal duct stenosis, retinal vascular occlusion, or infrequently uveitis should raise the question of possible WG. A thorough clinical examination, laboratory testing, radiologic imaging, and histologic examination are essential to diagnosing WG and excluding potential mimics. Previously a uniformly fatal disease, treatment with cytotoxic and immunosuppressive agents has greatly improved survival. Treatment-related morbidity is a serious limitation of conventional therapies, leading to numerous ongoing studies of alternative agents. (Surv Ophthalmol 55:429-444, 2010. (C) 2010 Elsevier Inc.

Treatment strategies targeting angiogenesis have demonstrated promising results in preclinical studies and clinical trials in patients with malignant gliomas. Anti-VEGF agents, either alone or in combination with chemotherapy, have been associated with reduction in vasogenic brain edema, and prolonged progression-free survival. Larger prospective clinical trials are needed to validate these results, and to assess the impact of these agents on overall survival. Unfortunately, antiangiogenic treatment inevitably fails in most patients. Further studies are needed to understand the molecular pathways that enable a tumor to evade antiangiogenic therapy.

The objective of this study was to determine the effects of sunitinib on signal transduction pathways and on gene expression of iodide-metabolizing proteins in papillary cancer cells with the RET/PTC1 rearrangement. Methods: We investigated the effects of sunitinib on cell growth, signal transduction pathways, and thyroid-specific gene expression in papillary thyroid cancer (PTC) cell lines that had the RET/PTC1 rearrangement. Results: Sunitinib inhibited proliferation of RET/PTC1 subclones in a time-and dose-related manner. The mean 50% lethal concentration in the RET/PTC1 subclones was 1.81 mu M. Incubation of RET/PTC1 cells with 1 mu M sunitinib inhibited their migration potential and transformed their morphology. Sunitinib inhibited RET autophosphorylation at Y1062 and the activation of signal transducer and activator of transcription 3 by blocking Y705 phosphorylation. Sunitinib caused cell cycle arrest in the G0/G1 phase and dephosphorylation of retinoblastoma protein, but did not induce apoptosis. Western blot analysis of the p38, MEK/ERK, and SAPK/JNK mitogen-activated protein kinase signal transduction pathways showed that sunitinib blocked ERK 1/2 and JNK phosphorylation in the cytoplasm. Sunitinib treatment of RET/PTC1 cell lines, in combination, with forskolin induced expression of the sodium (Na)/iodide (I) symporter (NIS) and the transcription factors that bind the NIS upstream enhancer. Mechanistically, the inhibition of both MEK/ERK and SAPK/JNK cytoplasmic pathways individually and in combination caused an increase in NIS gene expression. Conclusion: Sunitinib appears to target the cytosolic MEK/ERK and SAPK/JNK pathways in the RET/PTC1 cell lines, suggesting that blocking these pathways is at least part of the mechanism by which sunitinib inhibits cell proliferation and causes stimulation of NIS gene expression in RET/PTC1 cells.

In this study we used an animal model of AD (TgCRND8 mice) to determine the effects of high-frequency stimulation (HFS) on non-amyloidogenic alpha-secretase activity and DBS in short-term memory. We tested our hypothesis using hippocampal slices (in vitro studies) from TgCRND8 mice to evaluate whether HFS increases a-secretase activity (non-amyloidogenic pathway) in the CA1 region. In a second set of experiments, we performed in vivo studies to evaluate whether DBS in midline thalamic region re-establishes hippocampal dependent short-term memory in TgCRND8 mice. The results showed that application of HFS to isolated hippocampal slices significantly increased synaptic plasticity in the CA1 region and promoted a 2-fold increase of non-amyloidogenic a-secretase activity, in comparison to low frequency stimulated controls from TgCRND8 mice. In the in vivo studies, DBS treatment facilitated acquisition of object recognition memory in TgCRND8 mice, in comparison to their own baseline before treatment. These results provide evidence that DBS could enhance short-term memory in the CA1 region of hippocampus in a mouse model of AD.

TI Diluted Blood Reperfusion as a Model for Transplantation of Ischemic Rat Livers: Alanine Aminotransferase Is a Direct Indicator of Viability SO TRANSPLANTATION PROCEEDINGS LA English DT Article ID MACHINE PERFUSION PRESERVATION; COLD-STORAGE; RECOVERY AB Donors after cardiac death present a significant pool of untapped organs for transplantation, and use of machine perfusion strategies has been an active focus area in experimental transplantation. However, despite 2 decades of research, a gold standard has yet to emerge for machine perfusion systems and protocols. Whole blood reperfusion has been used as a surrogate for organ transplantation, especially as a model for the short-term response posttransplantation, and for optimization of perfusion systems. Although it is known that there is a strong correlation between liver function in whole-blood reperfusion and survival, the exact nature of these correlations, and to what extent they can be considered as an indicator of viability for transplantation/recipient survival, remain unclear. In this work, we demonstrate that diluted whole-blood reperfusion can be used as a direct model for transplantation of ischemic rat liver grafts. Specifically, we show that recipient survival can be predicted based simply on the value of alanine aminotransferase during perfusion, providing quantitative criteria of viability for use in this animal model. These results indicate that in the rat model graft survival is highly correlated with hepatocellular damage. C1 [Yarmush, M. L.] Shriners Hosp Children, Boston, MA 02114 USA.

TI Auditory Brainstem Circuits That Mediate the Middle Ear Muscle Reflex SO TRENDS IN AMPLIFICATION LA English DT Article DE acoustic reflex; middle ear muscle; pseudo-rabies virus; auditory prosthetic devices; middle ear ossicles AB The middle ear muscle (MEM) reflex is one of two major descending systems to the auditory periphery. There are two middle ear muscles (MEMs): the stapedius and the tensor tympani. In man, the stapedius contracts in response to intense low frequency acoustic stimuli, exerting forces perpendicular to the stapes superstructure, increasing middle ear impedance and attenuating the intensity of sound energy reaching the inner ear (cochlea). The tensor tympani is believed to contract in response to self-generated noise (chewing, swallowing) and nonauditory stimuli. The MEM reflex pathways begin with sound presented to the ear. Transduction of sound occurs in the cochlea, resulting in an action potential that is transmitted along the auditory nerve to the cochlear nucleus in the brainstem (the first relay station for all ascending sound information originating in the ear). Unknown interneurons in the ventral cochlear nucleus project either directly or indirectly to MEM motoneurons located elsewhere in the brainstem. Motoneurons provide efferent innervation to the MEMs. Although the ascending and descending limbs of these reflex pathways have been well characterized, the identity of the reflex interneurons is not known, as are the source of modulatory inputs to these pathways. The aim of this article is to (a) provide an overview of MEM reflex anatomy and physiology, (b) present new data on MEM reflex anatomy and physiology from our laboratory and others, and (c) describe the clinical implications of our research.

Materials and methods: The debate was centered on presentations arguing for radical prostatectomy (RP) or radiotherapy as the optimal treatment for this condition. The meeting presentations are summarized by their respective presenters herein. Results: Dr. James Eastham presents the varied definitions for "high-risk" prostate cancer as strongly influencing which patients end up in this cohort. Based upon this, between 3% and 38% of patients with high-risk features could be defined as "high-risk". Despite that, these men do not have a uniformly poor prognosis after RP, and attention to surgical principles as outlined improve outcomes. Disease-specific survival at 12 years is excellent and up to one-half of these men may not need adjuvant or salvage therapies, depending on their specific disease characteristics. Adjuvant or salvage radiotherapies improve outcomes and are part of a sequential approach to treating these patients. Dr. Anthony Zietman presented radiotherapy as the gold-standard based upon large, randomized clinical trials of intermediate- and high-risk prostate cancer patients. Compared with androgen deprivation alone, the addition of radiotherapy provided a 12% cancer-specific survival advantage and 10% overall survival advantage. Dose escalation seems to confer further improvements in cancer control without significant escalation of toxicities, with more data forthcoming. Conclusions: There are no randomized trials comparing RP to radiotherapy for any risk category. In high-risk prostate cancer patients, both approaches have potential benefits and cumulative toxicities that must be matched to disease characteristics and patient expectations in selecting a treatment course.

CA SEARCH Database Study Grp TI Outcomes After Radical Prostatectomy Among Men Who Are Candidates for Active Surveillance: Results From the SEARCH Database SO UROLOGY LA English DT Article ID AGENT-ORANGE; CANCER; RISK; BIOPSY; PREDICTOR; RECURRENCE; MANAGEMENT; CARCINOMA; VETERANS; EXPOSURE AB OBJECTIVE We sought to evaluate outcomes after radical prostatectomy among men with low-risk prostate cancer who would be candidates for active surveillance. METHODS Using the Shared Equal Access Regional Cancer Hospital (SEARCH) database of men treated with radical prostatectomy at multiple equal-access medical centers between 1988 and 2007, 398 of 2062 men (19%) met our criteria for potential active surveillance: clinical stage T1c or T2a, prostate-specific antigen (PSA) < 10 ng/mL, Gleason sum <= 6, and no more than 1 or 2 positive cores on at least a sextant biopsy. We examined the risk of adverse pathology, biochemical progression, and PSA doubling time (PSADT) at the time of recurrence. We used a Cox proportional hazards model to determine the significant predictors of PSA progression. RESULTS Of the men with low-risk prostate cancer, 85% had organ-confined disease, only 2% had seminal vesicle invasion, and no patient had lymph node metastasis. The 5- and 10 year PSA-free survival rates were 81% (95% CI: 76-86%) and 66% (95% CI: 54-76%). On multivariate analysis, older age (P = .005), Agent Orange exposure (P = .02), and obesity (P = .03) were all significantly associated with biochemical failure. Mean and median PSADT among men who experienced recurrence were 37 and 20 months. Only 3 patients experienced recurrence with PSADT < 9 months. CONCLUSIONS Most men with low-risk prostate cancer treated with radical prostatectomy experience long-term PSA control. Those who did experience recurrence often did so with a long PSADT. Consistent with prior SEARCH database reports, older age, Agent Orange exposure, and obesity increased the risk of recurrence. UROLOGY 76: 695-702, 2010. (C) 2010 Elsevier Inc. All rights reserved.

Using image quantitation, AIP cases (n = 10) with pre- and post-surgical glucose values were compared with chronic pancreatitis (CP) and normal pancreas (NP) regarding percent chromogranin immunohistochemistry (IHC) positivity as a surrogate marker of endocrine endowment; intra-islet T and B lymphocyte and plasma cell enumeration with CD3, CD20, and IgG4 IHC; and CD34 IHC islet vascularity quantitation. Postsurgical GCI, noted in 8/10 (80%) AIP cases, approached statistical significance (P = 0.07) compared to CP. Endocrine endowment reduction, noted by a lower percent of chromogranin + pancreatic parenchyma, was seen in AIP (4.54%) and CP (3.20%) compared to NP (7.95%); only the CP decrease was statistically significant (P = 0.02) since AIP often had ductular endocrine neogenesis. Regression suggested an inverse correlation between endocrine endowment and GCI in AIP (R = 0.62, P= 0.06). AIP islets were smaller and disrupted by inflammatory cell infiltration. Compared to CP, AIP islets had higher CD3 + and CD20 + cell densities. IgG4 + plasma cells were often present at a high density in AIP but typically preserved the islets. Intra-islet CD34 staining showed a lower average vascularity in AIP compared to NP (P= 0.05). This study reaffirms postsurgical GCI in AIP. Prominent intra-islet inflammation and decreased vascularity in AIP may contribute to diabetogenic effects. Endocrine cell neogenesis and relative islet preservation despite islet inflammatory infiltration may explain the paradoxical GCI in AIP.

Members of species A are implicated as gastrointestinal pathogens and were shown to be tumorigenic in rodents. These whole genome and in silico proteome data are important as references for reexamining and integrating earlier work and observations based on lower resolution techniques, such as restriction enzyme digestion patterns, particularly for hypotheses based on pre-genomics data. Additionally, the genome of HAdV-A18 will also serve as reference for current studies examining the molecular evolution and origins of human and simian adenoviruses, particularly genome recombination studies. Applications of this virus as a potential vector for gene delivery protocols may be practical as data accumulate on this and other adenovirus genomes. (C) 2010 Elsevier Inc. All rights reserved.

However, candidiasis among non-trauma emergency surgery (NTES) patients has not been previously investigated. Herein we describe the incidence of both colonization and infection from Candida and risk factors for invasive disease in this population. Results: Of all 289 eligible patients, 63 (21.7%) fulfilled the criteria for Candida infection and 110 (38%) were included in the Candida colonization group. Interestingly, from the 63 patients with invasive candidiasis, 25 (39.7%) were infected by a non-albicans species. Upon multivariate analyses, ventilator-associated pneumonia (VAP) (Odds Ratio [OR]: 2.34; 95%, Confidence Interval [CI]: 1,213-4,533, p = 0.0112), bacteremia (OR: 4,778; 95% CI: 1,519-15,029, p = 0.0075) and surgical complications (OR: 3.903; 95% CI: 1,335-11,412, p = 0.0129) were independent risk factors for the development of Candida infection. Candida infection and colonization were both found to correlate with approximately $40,000-100,000 mean additional costs). Interestingly, candidemia was associated with 63% all-cause mortality. For all other forms of candidiasis, mortality was not significantly different among groups. Methods: For this retrospective single center study we included all NTES patients with ICU stay >= 4 days from May 1(st), 2002 to April 30(th), 2007. Patients were divided into 3 non-overlapping groups: (1) patients with Candida-infection, (2) patients with Candida colonization and (3) patients with negative Candida cultures. Groups were compared by univariate and multivariate analyses to identify significant risk factors for invasive candidiasis. Conclusion: We found that Candida infection is alarmingly high among NTES patients with prolonged intensive care unit (ICU) stay. Surgical complications and bacterial infections (VAP and bacteraemia) were significantly correlated with the development of candidiasis. Candidiasis reached a rate of 21.7/100 discharges, which is significantly higher than most established high-risk populations for candidiasis. Future studies should review the need for antifungal prophylaxis on this population.

Here we study the epidemiology and economic impact of Candida and examine potential risk factors for Candida infection in this population. Results: 374 patients were included. Upon comparisons between groups, candidiasis patients received significantly more blood transfusions (p = 0.013), antibiotics (p = 0.005) and total parenteral nutrition (TPN) (p = 0.004), had a longer duration of mechanical ventilation (MV) (p = 0.008) and underwent more laparotomy procedures than Candida free patients (56.5% versus 16.4%; p < 0.001). Surgical complications (13% versus 1.4%; p = 0.013), injury of the upper (13% versus 0.9%; p = 0.007) and lower gastrointestinal tract (8.7% versus 0.9%; p = 0.048) and bacterial wound or intra-abdominal infections (17.4% versus 1.9%; p = 0.004) were also more common in candidiasis patients. Upon multivariate analysis, patients receiving TPN had 7-fold higher odds for developing candidiasis [Odds ratio (OR): 7.2; 95% Confidence interval (CI): 2.6-19.4; p = 0.0001]. Other predisposing factors included laparotomy (OR: 3.8, 95% CI: 1.5-9.9; p = 0.0057) and female gender (OR: 5.7; 95% CI: 2.1-15.6; p = 0.0007). Average total hospital charges were higher for patients with Candida infection compared to patients with Candida colonization or without a positive Candida culture. Methods: In this 5-year retrospective study, all severely injured patients with = 4 days of intensive care unit stay were included, with the primary outcome being Candida infection. We identified 3 distinct patient groups: (1) The Candida infection, (2) The Candida colonization and (3) the Candida-free group. All comparisons between groups with p values <= 0.2 from the univariate analysis were entered into stepwise logistic regression to identify independent risk factors for candidiasis. Conclusions: TPN, laparotomy and female gender independently predict the development of candidiasis among trauma patients. Severely injured women requiring laparotomy and TPN therapy should be carefully managed for the possibility of increased risk for candidiasis.

TI Multi-Dimensional Risk Factor Patterns Associated with Non-Use of Highly Active Antiretroviral Therapy among Human Immunodeficiency Virus-Infected Women SO WOMENS HEALTH ISSUES LA English DT Article ID HIV-SEROPOSITIVE WOMEN; UNITED-STATES; DRUG-USE; INTERAGENCY HIV; SUBSTANCE USE; ADHERENCE; SYMPTOMS; BEHAVIOR; PREDICTORS; SAMPLE AB Objectives: Relationships between non-use of highly active antiretroviral therapy (HAART), race/ethnicity, violence, drug use, and other risk factors are investigated using qualitative profiles of five risk factors (unprotected sex, multiple male partners, heavy drinking, crack, cocaine or heroin use, and exposure to physical violence) and association of the profiles and race/ethnicity with non-use of HAART over time. Methods: A hidden Markov model was used to summarize risk factor profiles and changes in profiles over time in a longitudinal sample of HIV-infected women enrolled in the Women's Interagency HIV Study with follow-up from 2002 to 2005 (n = 802). Results: Four risk factor profiles corresponding to four distinct latent states were identified from the five risk factors. Trajectory analysis indicated that states characterized by high probabilities of all risk factors or by low probabilities of all risk factors were both relatively stable over time. Being in the highest risk state did not significantly elevate the odds of HAART non-use (odds ratio [OR] 1.05; 95% confidence interval (CI], 0.6-1.8). However, being in a latent state characterized by elevated probabilities of heavy drinking and exposure to physical violence, along with slight elevations in three other risk factors, significantly increased odds of HAART non-use (OR, 1.4; 95% CI, 1.1-1.9). Conclusion: The research suggests that HAART use might be improved by interventions aimed at women who are heavy drinkers with recent exposure to physical violence and evidence of other risk factors. More research about the relationship between clustering and patterns of risk factors and use of HAART is needed. Copyright (C) 2010 by the Jacobs Institute of Women's Health.

TI Anthrax Toxin Receptor 1/Tumor Endothelial Marker 8: Mutation of Conserved Inserted Domain Residues Overrides Cytosolic Control of Protective Antigen Binding SO BIOCHEMISTRY LA English DT Article ID CAPILLARY MORPHOGENESIS PROTEIN-2; CD11B A-DOMAIN; I-DOMAIN; SECONDARY STRUCTURE; CRYSTAL-STRUCTURE; PORE FORMATION; LETHAL TOXIN; INTEGRIN REGULATION; CIRCULAR-DICHROISM; DISULFIDE BOND AB Anthrax toxin receptor I (ANTX RI)/tumor endothelial marker 8 (TEM 8) is one of two known proteinaceous cell surface anthrax toxin receptors. A metal ion dependent adhesion site (MIDAS) present in the integrin-like inserted (I) domain of ANTXRI mediates the binding of the anthrax toxin subunit, protective antigen (PA). Here we provide evidence that single point mutations in the 1 domain can override regulation of ANTX RI ligand-binding activity mediated by intracellular signals. A previously reported MIDAS mutant of ANTXRI (T118A) was found to retain normal metal ion binding and secondary structure but failed to bind PA, consistent with a locked inactive state. Conversely, mutation of a conserved I domain phenylalanine residue to a tryptophan (F205W) increased the proportion of cell-surface ANTX RI that bound PA, consistent with a locked active state. Interestingly, the K(D) and total amount of PA bound by the isolated ANTXRI I domain were not affected by the F205W mutation, indicating that ANTXRI is preferentially found in the active state in the absence of inside-out signaling. Circular dichroism (CD) spectroscopy and (1)H-(15)N heteronuclear single-quantum coherence (HSQC) nuclear magnetic resonance (NMR) revealed that structural changes between T118A, F205W, and WT I domains were minor despite a greater than 10(3)-fold difference in their abilities to bind toxin. Regulation of toxin binding has important implications for the design of toxin inhibitors and for the targeting of ANTXRI for antitumor therapies.

Background Recent literature has shown that the application of CRT in clinical practice frequently does not adhere to evidence-based consensus guidelines. Factors underlying these practices have not been fully explored. Methods From the National Cardiovascular Data Registry's Implantable Cardiac-Defibrillator Registry, we defined a cohort of 45,392 cardiac resynchronization therapy-defibrillator (CRT-D) implants between January 2006 and June 2008 with a primary prevention indication. We defined "off-label" implants as those in which the ejection fraction was >35%, the New York Heart Association functional class was below III, or the QRS interval duration was <120 ms in the absence of a documented need for ventricular pacing. The relationships between patient, implanting physician, and hospital characteristics with off-label use were explored with multivariable hierarchical logistic regression models. Results Overall, 23.7% of devices were placed without meeting all 3 implant criteria, most often due to New York Heart Association functional class below III (13.1% of implants) or QRS interval duration <120 ms (12.0%). Atrial fibrillation/flutter, previous percutaneous coronary intervention, and the performance of an electrophysiology study before implant were independently associated with increased odds of off-label use, whereas diabetes mellitus, increasing age, and female sex were associated with decreased odds. Physician training and insurance payer were weakly associated with the likelihood of off-label use. Conclusions Nearly 1 in 4 patients receiving CRT devices in the study time frame did not meet guideline-based indications. Given the evolving evidence base supporting the use of CRT, these practices require careful scrutiny.

TI Seasonal prevalence of MS disease activity SO NEUROLOGY LA English DT Article ID MULTIPLE-SCLEROSIS EXACERBATIONS; LESIONS; FLUCTUATIONS; PROGRESSION; DISABILITY; TRIALS; REPAIR AB Objective: This observational cohort study investigated the seasonal prevalence of multiple sclerosis (MS) disease activity (likelihood and intensity), as reflected by new lesions from serial T2-weighted MRI, a sensitive marker of subclinical disease activity. Methods: Disease activity was assessed from the appearance of new T2 lesions on 939 separate brain MRI examinations in 44 untreated patients with MS. Likelihood functions for MS disease activity were derived, accounting for the temporal uncertainty of new lesion occurrence, individual levels of disease activity, and uneven examination intervals. Both likelihood and intensity of disease activity were compared with the time of year (season) and regional climate data (temperature, solar radiation, precipitation) and among relapsing and progressive disease phenotypes. Contrast-enhancing lesions and attack counts were also compared for seasonal effects. Results: Unlike contrast enhancement or attacks, new T2 activity revealed a likelihood 2-3 times higher in March-August than during the rest of the year, and correlated strongly with regional climate data, in particular solar radiation. In addition to the likelihood or prevalence, disease intensity was also elevated during the summer season. The elevated risk season appears to lessen for progressive MS and occur about 2 months earlier. Conclusion: This study documents evidence of a strong seasonal pattern in subclinical MS activity based on noncontrast brain MRI. The observed seasonality in MS disease activity has implications for trial design and therapy assessment. The observed activity pattern is suggestive of a modulating role of seasonally changing environmental factors or season-dependent metabolic activity. Neurology (R) 2010;75:799-806 C1 [Meier, D.

Here, we describe how the nucleoside diphosphate kinase Nm23-H1, a protein with a known link to cancer progression, regulates a critical step during cytokinesis. Nm23-H1 acts to provide a local source of GTP for the GTPase dynamin. Loss of Nm23-H1 in diploid cells leads to cytokinetic furrow regression, followed by cytokinesis failure and generation of tetraploid cells. Loss of dynamin phenocopies loss of Nm23-H1, and ectopic overexpression of WT dynamin complements the loss of Nm23-H1. In the absence of p53 signaling, the tetraploid cells resulting from loss of Nm23-H1 continue cycling and develop classic hallmarks of tumor cells. We thus provide evidence that the loss of Nm23-H1, an event suspected to promote metastasis, may additionally function at an earlier stage of tumor development to drive the acquisition of chromosomal instability.

TI Sucrose nonfermenting AMPK-related kinase (SNARK) mediates contraction-stimulated glucose transport in mouse skeletal muscle SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE LKB1; Akt Substrate of 160 kDa; TBC1D1; exercise ID ACTIVATED PROTEIN-KINASE; GLUT4 TRANSLOCATION; INSULIN SENSITIVITY; IN-VITRO; RAT; LKB1; METABOLISM; EXERCISE; PHOSPHORYLATION; IDENTIFICATION AB The signaling mechanisms that mediate the important effects of contraction to increase glucose transport in skeletal muscle are not well understood, but are known to occur through an insulin-independent mechanism. Muscle-specific knockout of LKB1, an upstream kinase for AMPK and AMPK-related protein kinases, significantly inhibited contraction-stimulated glucose transport. This finding, in conjunction with previous studies of ablated AMPK alpha 2 activity showing no effect on contraction-stimulated glucose transport, suggests that one or more AMPK-related protein kinases are important for this process. Muscle contraction increased sucrose nonfermenting AMPK-related kinase (SNARK) activity, an effect blunted in the muscle-specific LKB1 knockout mice. Expression of a mutant SNARK in mouse tibialis anterior muscle impaired contraction-stimulated, but not insulin-stimulated, glucose transport. Whole-body SNARK heterozygotic knockout mice also had impaired contraction-stimulated glucose transport in skeletal muscle, and knockdown of SNARK in C2C12 muscle cells impaired sorbitol-stimulated glucose transport. SNARK is activated by muscle contraction and is a unique mediator of contraction-stimulated glucose transport in skeletal muscle.

The use of light as a remote-activation mechanism for drug delivery has received increased attention due to its advantages in highly specific spatial and temporal control of compound release. Photo-triggered theranostic constructs could facilitate an entirely new category of clinical solutions which permit early recognition of the disease by enhancing contrast in various imaging modalities followed by the tailored guidance of therapy. Finally, such theranostic agents could aid imaging modalities in monitoring response to therapy. This article reviews recent developments in the use of light-triggered theranostic agents for simultaneous imaging and photoactivation of therapeutic agents. Specifically, we discuss recent developments in the use of theranostic agents for photodynamic-, photothermal- or photo-triggered chemotherapy for several diseases. Published by Elsevier B.V.

TI Health-Related Quality of Life in Parkinson disease: Correlation between Health Utilities Index III and Unified Parkinson's Disease Rating Scale (UPDRS) in US male veterans SO HEALTH AND QUALITY OF LIFE OUTCOMES LA English DT Article ID ECONOMIC-IMPACT; DISORDERS; DETERMINANTS; STIMULATION; POPULATION; PREDICTORS; SELECTION; SYMPTOMS; COMMON; TRIAL AB Objective: To apply a scaled, preference-based measure to the evaluation of health-related quality of life (HRQoL) in Parkinson's disease (PD); to evaluate the relationship between disease-specific rating scales and estimated HRQoL; and to identify predictors of diminished HRQoL. Background: Scaled, preference-based measures of HRQoL ("utilities") serve as indices of impact of disease, and can be used to generate quality-adjusted estimates of survival for health-economic evaluations. Evaluation of utilities for PD and their correlation with standard rating scales have been limited. Methods: Utilities were generated using the Health Utilities Index Mark III (HUI-III) on consecutive patients attending a PD Clinic between October 2003 and June 2006. Disease severity, medical, surgical (subthalamic nucleus deep brain stimulation (STN-DBS)), and demographic information were used as model covariates. Predictors of HUI-III utility scores were evaluated using the Wilxocon rank-sum test and linear regression models. Results: 68 men with a diagnosis of PD and a mean age of 74.0 (SD 7.4) were included in the data analysis. Mean HUI-III utility at first visit was 0.45 (SD 0.33). In multivariable models, UPDRS-II score (r(2) = 0.56, P < 0.001) was highly predictive of HRQoL. UPDRS-III was a weaker, but still significant, predictor of utility scores, even after adjustment for UPDRS-II (P = 0.01). Conclusions: Poor self-care in PD reflected by worsening UPDRS-II scores is strongly correlated with low generic HRQoL. HUI-III-based health utilities display convergent validity with the UPDRS-II. These findings highlight the importance of measures of independence as determinants of HRQoL in PD, and will facilitate the utilization of existing UPDRS data into economic analyses of PD therapies.

Foxp3(+) regulatory T (T reg) cells may be involved, but the evidence has been conflicting. We investigated this issue in mice derived from the NOD model, which were engineered so that T reg populations were perturbed, or could be manipulated by acute ablation or transfer. The data highlighted the involvement of Foxp3(+) cells in anti-CD3 action. Rather than a generic influence on all T reg cells, the therapeutic effect seemed to involve an similar to 50-60-fold expansion of previously constrained T reg cell populations; this expansion occurred not through conversion from Foxp3(-) conventional T (T conv) cells, but from a proliferative expansion. We found that T reg cells are normally constrained by TCR-specific niches in secondary lymphoid organs, and that intraclonal competition restrains their possibility for conversion and expansion in the spleen and lymph nodes, much as niche competition limits their selection in the thymus. The strong perturbations induced by anti-CD3 overcame these niche limitations, in a process dependent on receptors for interleukin-2 (IL-2) and IL-7.

TI A novel interaction between FlnA and Syk regulates platelet ITAM-mediated receptor signaling and function SO JOURNAL OF EXPERIMENTAL MEDICINE LA English DT Article ID VON-WILLEBRAND-FACTOR; GLYCOPROTEIN-IB-ALPHA; FILAMIN-A BINDING; BERNARD-SOULIER-SYNDROME; PERIVENTRICULAR HETEROTOPIA; MEMBRANE SKELETON; GAMMA-CHAIN; CYTOPLASMIC DOMAIN; STRUCTURAL BASIS; ARP2/3 COMPLEX AB Filamin A (FlnA) cross-links actin filaments and connects the Von Willebrand factor receptor GPIb-IX-V to the underlying cytoskeleton in platelets. Because FlnA deficiency is embryonic lethal, mice lacking FlnA in platelets were generated by breeding FlnA(loxP/loxP) females with GATA1-Cre males. FlnA(loxP/y) GATA1-Cre males have a macrothrombocytopenia and increased tail bleeding times. FlnA-null platelets have decreased expression and altered surface distribution of GPIb. because they lack the normal cytoskeletal linkage of GPIb. to underlying actin filaments. This results in similar to 70% less platelet coverage on collagen-coated surfaces at shear rates of 1,500/s, compared with wild-type platelets. Unexpectedly, however, immunoreceptor tyrosine-based activation motif (ITAM)- and ITAM-like-mediated signals are severely compromised in FlnA-null platelets. FlnA-null platelets fail to spread and have decreased alpha-granule secretion, integrin alpha IIb beta 3 activation, and protein tyrosine phosphorylation, particularly that of the protein tyrosine kinase Syk and phospholipase C-gamma 2, in response to stimulation through the collagen receptor GPVI and the C-type lectin-like receptor 2. This signaling defect was traced to the loss of a novel FlnA-Syk interaction, as Syk binds to FlnA at immunoglobulin-like repeat 5. Our findings reveal that the interaction between FlnA and Syk regulates ITAM- and ITAM-like-containing receptor signaling and platelet function.

Intrinsic optical imaging (IOI) and laser speckle provides measures of deoxyhemoglobin (HbR) and oxyhemoglobin (HbO(2)) concentrations, blood volume (BV) and blood flow (BF) at high spatial and temporal resolution. In this study we used IOI and laser speckle to characterize the hemodynamic response to neuronal activation in the lumbar spinal cord of anaesthetized rats (N = 9). We report consistent temporal variations of HbR, HbO(2), BV and BF located ipsilaterally at L3-L5. Responses were significantly higher when stimulation intensity was increased. Vascular changes extended several millimetres from the epicenter, supporting the venous drainage observed in functional magnetic resonance imaging studies. (C) 2010 Elsevier B.V. All rights reserved.

TI Assaying multiple biochemical variables from the same tissue sample SO JOURNAL OF NEUROSCIENCE METHODS LA English DT Article DE Sodium fluoride; Sonication; Dopamine; Parkinson's disease; Tyrosine hydroxylase; Dopamine Transporter; Phosphorylation; ERK1/2; Akt ID SUBSTANTIA-NIGRA; HUMAN BRAIN AB Experiments often involve multiple analyses, such as assays of neurotransmitters and proteins, and this can require different initial sample preparations. Typically, this is accomplished by using different animals or different tissue samples from the same animal. Either approach renders comparisons between assays more variable and greatly increases the effort and/or cost. Using tissue collected from rat striatum and molecules of special relevance to studies of Parkinson's disease, we show that tissue sonication in water prior to aliquoting into the appropriate concentrated solutions (e.g. HClO4 and lysis buffers) permits several types of measurements to be made from the same initial samples. Dopamine and its metabolite homovanillic acid, serotonin and its metabolite 5-hydroxyindoleacetic acid, tyrosine hydroxylase and its phosphorylation at Ser19 and Ser31, and the dopamine transporter were unaffected. However, phospho-Akt levels fell slightly and phospho-ERK1/2 tended to drop. We also present a simple technique to preserve phosphorylation state of proteins such as ERK1/2 by perfusing animals through the heart with a phosphatase inhibitor, NaF. Dopamine metabolite dihydroxyphenyl acetic acid (DOPAC) levels were raised with both techniques, however. The general principles reported here are likely to apply to other brain regions, facilitate multiple comparisons of variables, increase efficiency, and decrease costs. (C) 2010 Elsevier B.V.

Tian, Qu TI Detecting changes in human cerebral blood flow after acute exercise using arterial spin labeling: Implications for fMRI SO JOURNAL OF NEUROSCIENCE METHODS LA English DT Article DE Acute exercise; Physical activity; Cerebral blood flow; fMRI BOLD; Physiological monitoring; End-tidal CO2 ID DYNAMIC EXERCISE; ACTIVATION AB The use of arterial spin labeling to measure cerebral blood flow (CBF) after acute exercise has not been reported. The aims of this study were to examine: (1) the optimal inversion time to detect changes in CBF after acute exercise and (2) if acute exercise alters CBF in the motor cortex at rest or during finger-tapping. Subjects (n = 5) performed 30 min of moderate intensity exercise on an electronically braked cycle ergometer (perceived exertion 'somewhat hard'). Before and after exercise, relative CBF was measured using multiple inversion time (TI) pulsed arterial spin labeling (PASL). Two multiple TI runs were obtained at rest and during 4 Hz finger-tapping. Four inversion times (675, 975, 1275, and 1575 ms) were acquired per run, with 20 interleaved pairs of tag and control images per inversion time (320 s run). The results indicated that global CBF increased approximately 20% following exercise, with significant differences observed at an inversion time of 1575 ms (p < .05). Finger-tapping induced CBF in the motor cortex significantly increased from before to after exercise at TI = 1575 ms (p < .01). These findings suggest changes in human cerebral blood flow that result from acute moderate intensity exercise can be detected afterwards using PASL at 3T with an inversion time of 1575 ms. The effect of prior acute exercise to increase motor cortex CBF during the performance of a motor task suggests future use of indices of functional activation should account for exercise-induced changes in cardio-pulmonary physiology and CBF.

But quantifying FRET rapidly is difficult to do because of crosstalk between free donor, free acceptor and FRET fluorescent signals when only excitation or emission property of a FRET sample is measured. If FRET is studied with excitation-emission matrix (EEM) measurements, because the fluorescence intensity maxima of donor, acceptor, and FRET emissions occupy different regions within the EEM, FRET fluorescence can be easily separated out by linear unmixing. In this paper, we report a novel high-speed Fourier Fluorescence Excitation Emission spectrometer, which simultaneously measures three projections of EEM from a FRET sample, which are excitation, emission and excitation-emission cross-correlation spectra. We demonstrate that these three EEM projections can be measured and unmixed in approximately 1 ms to provide rapid quantitative FRET in the presence of free donors and acceptors. The system can be utilized to enable real-time biochemistry reaction studies.

In addition to foreign antigens, NKT cells react with endogenous self lipids. However, in the face of stimulating self antigen, it remains unclear how overstimulation of NKT cells is avoided. We hypothesized that constantly degraded endogenous antigen only accumulates upon inhibition of alpha-galactosidase A (alpha-Gal-A) in lysosomes. Here, we show that alpha-Gal-A deficiency caused vigorous activation of NKT cells. Moreover, microbes induced inhibition of alpha-Gal-A activity in antigen-presenting cells. This temporary enzyme block depended on Toll-like receptor (TLR) signaling and ultimately triggered lysosomal lipid accumulation. Thus, we present TLR-dependent negative regulation of alpha-Gal-A as a mechanistic link between pathogen recognition and self lipid antigen induction for NKT cells.

We previously demonstrated an absolute requirement for the lipid chemoattractant leukotriene B(4) (LTB(4)) and its receptor BLT1 for neutrophil recruitment into the joint in autoantibody-induced arthritis. We now demonstrate that BLT1 is required for neutrophils to deliver IL-1 into the joint to initiate arthritis. IL-1-expressing neutrophils amplify arthritis through the production of neutrophil-active chemokines from synovial tissue cells. CCR1 and CXCR2, two neutrophil chemokine receptors, operate nonredundantly to sequentially control the later phase of neutrophil recruitment into the joint and mediate all neutrophil chemokine activity in the model. Thus, we have uncovered a complex sequential relationship involving unique contributions from the lipid mediator LTB(4), the cytokine IL-1, and CCR1 and CXCR2 chemokine ligands that are all absolutely required for effective neutrophil recruitment into the joint.

MBL binds to mannose and N-acetylglucosamine residues present on the glycopolymers of microorganisms. Human serum MBL functions as an opsonin and activates the lectin complement pathway. However, which glycopolymer of microorganism is recognized by MBL is still uncertain. Here, we show that wall teichoic acid of Staphylococcus aureus, a bacterial cell surface glycopolymer containing N-acetylglucosamine residue, is a functional ligand of MBL. Whereas serum MBL in adults did not bind to wall teichoic acid because of an inhibitory effect of anti-wall teichoic acid antibodies, MBL in infants who had not yet fully developed their adaptive immunity could bind to S. aureus wall teichoic acid and then induced complement C4 deposition. Our data explain the molecular reasons of why MBL-deficient infants are susceptible to S. aureus infection.

Mct8 (monocarboxylate transporter 8), expressed predominantly in the brain and placenta, mediates thyroid hormone uptake from the circulation and is required for normal neural development. RA induces differentiation of F9 mouse teratocarcinoma cells toward neurons as well as extraembryonal endoderm. We hypothesized that Mct8 is functionally expressed in F9 cells and induced by RA. All-trans-RA (tRA) and other RA receptor (RAR) agonists dramatically (>300-fold) induced Mct8. tRA treatment significantly increased uptake of triiodothyronine and thyroxine (4.1- and 4.3-fold, respectively), which was abolished by a selective Mct8 inhibitor, bromosulfophthalein. Sequence inspection of the Mct8 promoter region and 5'-rapid amplification of cDNA ends PCR analysis in F9 cells identified 11 transcription start sites and a proximal Sp1 site but no TATA box. tRA significantly enhanced Mct8 promoter activity through a consensus RA-responsive element located 6.6 kilobases upstream of the coding region. A chromatin immunoprecipitation assay demonstrated binding of RAR and retinoid X receptor to the RA response element. The promotion of thyroid hormone uptake through the transcriptional up-regulation of Mct8 by RAR is likely to be important for extraembryonic endoderm development and neural differentiation. This finding demonstrates cross-talk between RA signaling and thyroid hormone signaling in early development at the level of the thyroid hormone transporter.

Accili, Domenico TI Uncoupling of Acetylation from Phosphorylation Regulates FoxO1 Function Independent of Its Subcellular Localization SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID FORKHEAD TRANSCRIPTION FACTOR; BETA-CELL FUNCTION; FACTOR FKHR; SIGNALING PATHWAY; GENE-EXPRESSION; 14-3-3 BINDING; PROTEIN FOXO1; LIFE-SPAN; INSULIN; DIFFERENTIATION AB The activity of transcription factor FoxO1 is regulated by phosphorylation-dependent nuclear exclusion and deacetylation-dependent nuclear retention. It is unclear whether and how these two post-translational modifications affect each other. To answer this question, we expressed FoxO1 cDNAs with combined mutations of phosphorylation and acetylation sites in HEK-293 cells and analyzed their subcellular localization patterns. We show that mutations mimicking the acetylated state (KQ series) render FoxO1 more sensitive to Akt-mediated phosphorylation and nuclear exclusion and can reverse the constitutively nuclear localization of phosphorylation-defective FoxO1. Conversely, mutations mimicking the deacetylated state (KR series) promote FoxO1 nuclear retention. Oxidative stress and the Sirt1 activator resveratrol are thought to promote FoxO1 deacetylation and nuclear retention, thus increasing its activity. Accordingly, FoxO1 deacetylation was required for the effect of oxidative stress (induced by H(2)O(2)) to retain FoxO1 in the nucleus. H(2)O(2) also inhibited FoxO1 phosphorylation on Ser-253 and Thr-24, the key insulin-regulated sites, irrespective of its acetylation. In contrast, the effect of resveratrol was independent of FoxO1 acetylation and its phosphorylation on Ser-253 and Thr-24, suggesting that resveratrol acts on FoxO1 in a Sirt1- and Akt-independent manner. The dissociation of deacetylation from dephosphorylation in H(2)O(2)-treated cells indicates that the two modifications can occur independently of each other. It can be envisaged that FoxO1 exists in multiple nuclear forms with distinct activities depending on the balance of acetylation and phosphorylation.

Methods: 40 hypertensive individuals without diabetes and with normal levels of cholesterol were examined. The participants were randomized either to ingest 10 g dried broccoli sprouts, a natural donor of glucosinolates with high in vitro antioxidative potential, for a 4 week period or to continue their ordinary diet and act as controls. Blood pressure, endothelial function measured by flow mediated dilation (FMD) and blood samples were obtained from the participants every other week and the content of glucosinolates was measured before and after the study. Measurements were blinded to treatment allocation. Results: In the interventional group overall FMD increased from 4% to 5.8% in the interventional group whereas in the control group FMD was stable (4% at baseline and 3.9% at the end of the study). The change in FMD in the interventional group was mainly due to a marked change in FMD in two participants while the other participants did not have marked changes in FMD. The observed differences were not statistically significant. Likewise significant changes in blood pressure or blood samples were not detected between or within groups. Diastolic blood pressure stayed essentially unchanged in both groups, while the systolic blood pressure showed a small non significant decrease (9 mm Hg) in the interventional group from a value of 153 mm Hg at start. Conclusion: Daily ingestion of 10 g dried broccoli sprouts does not improve endothelial function in the presence of hypertension in humans.

Ezrin and moesin are both expressed in mature lymphocytes, where they play overlapping roles in cell signaling and polarity, but their role in lymphoid development has not been explored. Methodology/Principal Findings: We characterized ERM protein expression in lymphoid tissues and analyzed the requirement for ezrin expression in lymphoid development. In wildtype mice, we found that most cells in the spleen and thymus express both ezrin and moesin, but little radixin. ERM protein expression in the thymus was differentially regulated, such that ezrin expression was highest in immature thymocytes and diminished during T cell development. In contrast, moesin expression was low in early thymocytes and upregulated during T cell development. Mice bearing a germline deletion of ezrin exhibited profound defects in the size and cellularity of the spleen and thymus, abnormal thymic architecture, diminished hematopoiesis, and increased proportions of granulocytic precursors. Further analysis using fetal liver chimeras and thymic transplants showed that ezrin expression is dispensable in hematopoietic and stromal lineages, and that most of the defects in lymphoid development in ezrin(-/-) mice likely arise as a consequence of nutritional stress. Conclusions/Significance: We conclude that despite high expression in lymphoid precursor cells, ezrin is dispensable for lymphoid development, most likely due to redundancy with moesin.

METHODS We conducted a multicenter, phase 1, dose-escalation trial of PLX4032 (also known as RG7204), an orally available inhibitor of mutated BRAF, followed by an extension phase involving the maximum dose that could be administered without adverse effects (the recommended phase 2 dose). Patients received PLX4032 twice daily until they had disease progression. Pharmacokinetic analysis and tumor-response assessments were conducted in all patients. In selected patients, tumor biopsy was performed before and during treatment to validate BRAF inhibition. RESULTS A total of 55 patients (49 of whom had melanoma) were enrolled in the dose-escalation phase, and 32 additional patients with metastatic melanoma who had BRAF with the V600E mutation were enrolled in the extension phase. The recommended phase 2 dose was 960 mg twice daily, with increases in the dose limited by grade 2 or 3 rash, fatigue, and arthralgia. In the dose-escalation cohort, among the 16 patients with melanoma whose tumors carried the V600E BRAF mutation and who were receiving 240 mg or more of PLX4032 twice daily, 10 had a partial response and 1 had a complete response. Among the 32 patients in the extension cohort, 24 had a partial response and 2 had a complete response. The estimated median progression-free survival among all patients was more than 7 months. CONCLUSIONS Treatment of metastatic melanoma with PLX4032 in patients with tumors that carry the V600E BRAF mutation resulted in complete or partial tumor regression in the majority of patients.

We investigated the intrinsic functional connectivity of PAG using resting fMRI data from 100 subjects. The results showed that PAG is functionally connected to ACC (rostral and pregenual ACC) and also rostral ventromedial medulla (RVM), forming a core ACC-PAG-RVM network for pain modulation even no pain stimulus is applied. The comparison between genders showed that for the contrast of female minus male, significant difference was observed at mid-cingulate cortex; for the contrast of male minus female, significant differences were observed at left medial orbital prefrontal cortex, and uncus; right insula/operculum and prefrontal cortex. We believe eluciation of this intrinsic PAG network duing the resting state will enhance our physiological and pathological understandings of the development and maintenance of chronic pain states.

TI Correlation Between Hybrid Capture II High-Risk Human Papillomavirus DNA Test Chemiluminescence Intensity From Cervical Samples With Follow-Up Histologic Results A Cytologic/Histologic Review of 367 Cases SO CANCER CYTOPATHOLOGY LA English DT Article DE cervical cytology; human papillomavirus (HPV) testing; SurePath; Hybrid Capture II ID ATYPICAL SQUAMOUS-CELLS; VIRAL LOAD; INTRAEPITHELIAL NEOPLASIA; UNDETERMINED SIGNIFICANCE; COST-EFFECTIVENESS; CANCER; WOMEN; HPV; CARCINOGENESIS; MANAGEMENT AB BACKGROUND: The Hybrid Capture II high-risk human papillomavirus (hrHPV) DNA test is a US Food and Drug Administration-approved nucleic acid hybridization assay using chemiluminescence for the semiquantitative detection of hrHPV in cervical samples. Patient samples and controls are used to calculate results as negative for hrHPV if <1.0, positive for hrHPV if >2.5, and "equivocal" if between 1.0 and 2.5. METHODS: The authors reported on the cervical histologic results of 209 patients demonstrating "equivocal" results for hrHPV from Sure Path (204 patients) or Thin Prep (5 patients) vials, and compared patients in this cohort with atypical squamous cells of undetermined significance (ASC-US) cytology on the index cervical Papanicolaou (Pap) test (Group 1: n = 148 patients) with a patient cohort demonstrating unequivocal positive hrHPV test results (Group 2; n = 148 patients). The chemiluminescence intensity of hrHPV tests from patients in Group 2 were correlated with the presence and severity of dysplasia on subsequent histologic results, and patients were thereby stratified for their subsequent risk of cervical intraepithelial neoplasia (CIN) types II/III. RESULTS: Approximately 97% of hrHPV tests demonstrating "equivocal" results were found to be positive at the time of retesting, and 15% of biopsied cases demonstrated CIN II or Ill. Results of follow-up histology after an ASC-US diagnosis, expressed as a percentage of the biopsied cohort, were: CIN II/III: 16.5% in Group 1 and 22.4% in Group 2; CIN 27% in Group 1 and 23.5% in Group 2; and negative: 56.5% in Group 1 and 54.1% in Group 2. Chemiluminescence intensity did not appear to be correlated with the severity of dysplasia. CONCLUSIONS: The percentage of high-grade CIN in the "equivocal" hrHPV cohort is highly significant and therefore the management of these patients should be similar to the unequivocally positive population. After an unequivocal positive hrHPV test, the hrHPV chemiluminescence intensity does not appear to further predict the rate of high-grade CIN. Cancer (Cancer Cytopathol) 2010;118:209-17.

This may reflect a mismatch between the interventions and the nature of the settings in which they are attempted. The application of complex adaptive systems (CAS) framework to understand clinical systems and inform efforts to improve them may lead to more successful interventions. We performed a systematic review of interventions to improve outcomes of patients with congestive heart failure (CHF) to examine whether interventions consistent with CAS are more likely to be effective. We then examine differences between interventions that are most effective for improving outcomes for patients with CHF versus previously published data for type 2 diabetes to explore the potential impact of the nature of the disease on the types of interventions that are more likely to be effective. Methods: We conducted a systematic review of the literature between 1998 and 2008 of organizational interventions to improve care of patients with CHF. Two independent reviewers independently assessed studies that met inclusion criteria to determine whether each reported intervention reflected one or more CAS characteristics. The effectiveness of interventions was rated as either 0 (no effect), 0.5 (mixed effect), or 1.0 (effective) based on the type, number, and significance of reported outcomes. Fisher's exact test was used to examine the association between CAS characteristics and intervention effectiveness. Specific CAS characteristics associated with intervention effectiveness for CHF were contrasted with previously published data for type 2 diabetes. Results and discussion: Forty-four studies describing 46 interventions met eligibility criteria. All interventions utilized at least one CAS characteristic, and 85% were either 'mixed effect' or 'effective' in terms of outcomes. The number of CAS characteristics present in each intervention was associated with effectiveness (p < 0.001), supporting the idea that interventions consistent with CAS are more likely to be effective. The individual CAS characteristics associated with CHF intervention effectiveness were learning, self-organization, and co-evolution, a finding different from our previously published analysis of interventions for diabetes. We suggest this difference may be related to the degree of uncertainty involved in caring for patients with diabetes versus CHF. Conclusion: These results suggest that for interventions to be effective, they must be consistent with the CAS nature of clinical systems. The difference in specific CAS characteristics associated with intervention effectiveness for CHF and diabetes suggests that interventions must also take into account attributes of the disease.

TI Cognitive Behavioral Therapy vs Relaxation With Educational Support for Medication-Treated Adults With ADHD and Persistent Symptoms A Randomized Controlled Trial SO JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION LA English DT Article ID DEFICIT HYPERACTIVITY DISORDER; DOUBLE-BLIND; ADOLESCENTS; PLACEBO AB Context Attention-deficit/hyperactivity disorder (ADHD) in adulthood is a prevalent, distressing, and impairing condition that is not fully treated by pharmacotherapy alone and lacks evidence-based psychosocial treatments. Objective To test cognitive behavioral therapy for ADHD in adults treated with medication but who still have clinically significant symptoms. Design, Setting, and Patients Randomized controlled trial assessing the efficacy of cognitive behavioral therapy for 86 symptomatic adults with ADHD who were already being treated with medication. The study was conducted at a US hospital between November 2004 and June 2008 (follow-up was conducted through July 2009). Of the 86 patients randomized, 79 completed treatment and 70 completed the follow-up assessments. Interventions Patients were randomized to 12 individual sessions of either cognitive behavioral therapy or relaxation with educational support (which is an attention-matched comparison). Main Outcome Measures The primary measures were ADHD symptoms rated by an assessor (ADHD rating scale and Clinical Global Impression scale) at baseline, post-treatment, and at 6- and 12-month follow-up. The assessor was blinded to treatment condition assignment. The secondary outcome measure was self-report of ADHD symptoms. Results Cognitive behavioral therapy achieved lower posttreatment scores on both the Clinical Global Impression scale (magnitude -0.0531; 95% confidence interval [CI], -1.01 to -0.05; P=.03) and the ADHD rating scale (magnitude -4.631; 95% CI, -8.30 to -0.963; P=.02) compared with relaxation with educational support. Throughout treatment, self-reported symptoms were also significantly more improved for cognitive behavioral therapy (beta=-0.41; 95% Cl, -0.64 to -0.17; P<001), and there were more treatment responders in cognitive behavioral therapy for both the Clinical Global Impression scale (53% vs 23%; odds ratio [OR], 3.80; 95% CI, 1.50 to 9.59; P=.01) and the ADHD rating scale (67% vs 33%; OR, 4.29; 95% Cl, 1.74 to 10.58; P=.002). Responders and partial responders in the cognitive behavioral therapy condition maintained their gains over 6 and 12 months. Conclusion Among adults with persistent ADHD symptoms treated with medication, the use of cognitive behavioral therapy compared with relaxation with educational support resulted in improved ADHD symptoms, which were maintained at 12 months.

SO JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION LA English DT Article ID CLINICAL-PRACTICE GUIDELINES; IMMUNIZATION PRACTICES ACIP; UNITED-STATES; EOSINOPHILIC BRONCHITIS; ADVISORY-COMMITTEE; PREVENTING TETANUS; PERSISTENT COUGH; EPIDEMIOLOGY; RECOMMENDATIONS; AZITHROMYCIN AB Context Pertussis is often overlooked as a cause of chronic cough, especially in adolescents and adults. Several symptoms are classically thought to be suggestive of pertussis, but the diagnostic value of each of them is uncertain. Objective To systematically review the evidence regarding the diagnostic value of 3 classically described symptoms of pertussis: paroxysmal cough, posttussive emesis, and inspiratory whoop. Data Sources, Study Selection, and Data Extraction We searched MEDLINE (January 1966 April 2010), EMBASE (January 1969 to April 2010), and the bibliographies of pertinent articles to identify relevant English-language studies. Articles were selected that included children older than 5 years, adolescents, or adults and confirmed the diagnosis of pertussis among patients with cough illness (of any duration) with an a priori defined accepted reference standard. Two authors independently extracted data from articles that met selection criteria and resolved any discrepancies by consensus. Data Synthesis Five prospective studies met inclusion criteria; 3 were used in the analysis. Presence of posttussive emesis (summary likelihood ratio [LR], 1.8; 95% confidence interval [Cl], 1.4-2.2) or inspiratory whoop (summary LR, 1.9; 95% Cl, 1.4-2.6) increases the likelihood of pertussis. Absence of paroxysmal cough (summary LR, 0.52; 95% Cl, 0.27-1.0) or posttussive emesis (summary LR, 0.58; 95% Cl, 0.44-0.77) reduced the likelihood. Absence of inspiratory whoop was less useful (summary LR, 0.78; 95% Cl, 0.66-0.93). No studies evaluated combinations of findings. Conclusions In a nonoutbreak setting, data to determine the diagnostic usefulness of symptoms classically associated with pertussis are limited and of relatively weak quality. The presence or absence of posttussive emesis or inspiratory whoop modestly change the likelihood of pertussis; therefore, clinicians must use their overall clinical impression to decide about additional testing or empirical treatment.

We evaluated effects of RTL401 (I-A(s) alpha 1 beta 1 + PLP-139-151) on splenocytes from SJL/J mice with EAE to study RTL-T cell tolerance-inducing mechanisms. RTLs bound to B, macrophages and DCs, through RTL-MHC-alpha 1 beta 1 moiety. RTL binding reduced CD11b expression on splenic macrophages/DC, and RTL401-conditioned macrophages/DC, not B cells, inhibited T cell activation. Reduced ability of RU- incubated splenocytes to transfer EAE was likely mediated through macrophages/DC, since B cells were unnecessary for RTL treatment of EAE. These results demonstrate a novel pathway of T cell regulation by RTL-bound APCs. (C) 2010 Elsevier B.V. All rights reserved.

Nahmias, Yaakov TI Transcriptional Regulation of Human and Rat Hepatic Lipid Metabolism by the Grapefruit Flavonoid Naringenin: Role of PPAR alpha, PPAR gamma and LXR alpha SO PLOS ONE LA English DT Article ID PROLIFERATOR-ACTIVATED RECEPTOR; FATTY-ACID OXIDATION; APOLIPOPROTEIN-B SECRETION; LIVER-X-RECEPTORS; HEPATOCYTE APO-B; NUCLEAR RECEPTORS; GENE-EXPRESSION; CROSS-TALK; CHOLESTEROL HOMEOSTASIS; NUTRITIONAL REGULATION AB Disruption of lipid and carbohydrate homeostasis is an important factor in the development of prevalent metabolic diseases such as diabetes, obesity, and atherosclerosis. Therefore, small molecules that could reduce insulin dependence and regulate dyslipidemia could have a dramatic effect on public health. The grapefruit flavonoid naringenin has been shown to normalize lipids in diabetes and hypercholesterolemia, as well as inhibit the production of HCV. Here, we demonstrate that naringenin regulates the activity of nuclear receptors PPARa, PPARc, and LXRa. We show it activates the ligand-binding domain of both PPARa and PPARc, while inhibiting LXRa in GAL4-fusion reporters. Using TR-FRET, we show that naringenin is a partial agonist of LXRa, inhibiting its association with Trap220 co-activator in the presence of TO901317. In addition, naringenin induces the expression of PPARa co-activator, PGC1a. The flavonoid activates PPAR response element (PPRE) while suppressing LXRa response element (LXRE) in human hepatocytes, translating into the induction of PPAR-regulated fatty acid oxidation genes such as CYP4A11, ACOX, UCP1 and ApoAI, and inhibition of LXRa-regulated lipogenesis genes, such as FAS, ABCA1, ABCG1, and HMGR. This effect results in the induction of a fasted-like state in primary rat hepatocytes in which fatty acid oxidation increases, while cholesterol and bile acid production decreases. Our findings explain the myriad effects of naringenin and support its continued clinical development. Of note, this is the first description of a non-toxic, naturally occurring LXRa inhibitor.

Sexual HIV transmission can be dramatically reduced through artificial insemination and sperm washing; however, most couples cannot access these resources. We propose that periconception pre-exposure prophylaxis (PrEP) could offer an important, complementary therapy to harm reduction counseling programs that aim to decrease HIV transmission for couples who choose to conceive. In this paper, we describe the potential benefits of periconception PrEP and define critical points of clarification prior to implementation of PrEP as part of a reproductive health program. We consider sexual transmission risk, current risk reduction options, PrEP efficacy, cost, adherence, resistance, fetal toxicity, and impact of PrEP counseling on entry into health services. We address PrEP in the context of other periconception HIV-prevention strategies, including antiretroviral treatment of the HIV-infected partner. We conclude that, should PrEP prove safe and efficacious in ongoing trials, periconception PrEP may offer a useful approach to minimize risk of HIV transmission for individuals of reproductive age in HIV-endemic countries.

TI Increased epicardial adipose tissue volume in HIV-infected men and relationships to body composition and metabolic parameters SO AIDS LA English DT Article ID HUMAN-IMMUNODEFICIENCY-VIRUS; INTIMA-MEDIA THICKNESS; HEART; RISK; FAT AB Epicardial fat accumulation may have important clinical consequences, yet little is known regarding this depot in HIV patients. We compared epicardial fat volume in 78 HIV-infected men and 32 HIV-negative controls. Epicardial fat volume was higher in HIV-infected patients than that in controls (P = 0.04). In HIV patients, epicardial fat volume was strongly associated with visceral adipose tissue area (rho = 0.76, P < 0.0001), fasting glucose (rho = 0.41, P = 0.001) and insulin (rho = 0.44, P = 0.0003). Relationships with glucose and insulin remained significant controlling for age, race, BMI, adiponectin, visceral adipose tissue and antiretroviral therapy. Epicardial fat may be an important fat depot in HIV-infected patients. C1 [Lo, Janet; Wei, Jeffrey; Grinspoon, Steven K.] Massachusetts Gen Hosp, Program Nutr Metab, Boston, MA 02114 USA.
