AB Background & Aims: Experimental studies indicate a potential cancer prevention effect for statins. Given the increasing prevalence of statin use, and the increasing incidence of hepatocellular carcinoma (HCC), the potential association between statins and HCC is an important issue to examine. Methods: We conducted a matched case-control study nested within a cohort of patients with diabetes. Cases comprised incident HCC at least 6 months after entry in the cohort. Controls were identified by incidence density sampling from patients who remained at risk at the date of the HCC diagnosis matched by age and sex. We identified fined statin prescriptions as well as several potential confounding conditions, medications, as well as propensity score to use statins. Odds ratios (ORs) as estimates of the relative risk for HCC associated with statin use and 95% confidence intervals were obtained using conditional logistic regression. Results: We examined 1303 cases and 5212 controls. The mean age was 72 years and 99% were men. A significantly smaller proportion of cases (34.3%) had at least one filled prescription for statins than controls (53.1%). There were no significant associations between HCC and nonstatin cholesterol- or triglyceride-lowering medications. The unadjusted OR for any statin prescription was 0.46 (9S% confidence interval, 0.40-0.517) and the adjusted OR was 0.74 (95% confidence interval, 0.64-0.87). To reduce the potential confounding effect of existing liver disease, we ran the analyses in a subgroup of patients without recorded liver disease; the ORs were slightly attenuated but remained highly significant for any statin prescription (0.63; 95% confidence interval, 0.50-0.78). Conclusions: Statin use is associated with a significant reduction in the risk of HCC among patients with diabetes.

TI Role of the Homeodomain Transcription Factor Bapx1 in Mouse Distal
Stomach Development

LA English
DT Article
ID EMBRYONAL GUT DEVELOPMENT; TARGETED DISRUPTION; AXIAL SKELETON; HOMEOBOX
GENE; HOX GENES; SPLEEN; EXPRESSION; MICE; DROSOPHILA; BAGPIPE
AB Background & Aims: Expansion and patterning of the endoderm generate a highly ordered, multiorgan digestive system in vertebrate animals. Among distal foregut derivatives, the gastric corpus, antrum, pylorus, and duodenum are distinct structures with sharp boundaries. Some homeodomain transcription factors expressed in gut mesenchyme convey positional information required for anterior-posterior patterning of the digestive tract. Barx1, in particular, controls stomach differentiation and morphogenesis. The Nirenberg and Kim homeobox gene Bapx1 (NW-2) has an established role in skeletal development, but its function in the mammalian gut is less clear. Methods: We generated a Bapx1(Cre) knock-in allele to fate map Bapx1-expressing cells and evaluate its function in gastrointestinal development. Results: Bapx1-expressing cells populate the gut mesenchyme with a rostral boundary in the hindstomach near the junction of the gastric corpus and antrum. Smooth muscle differentiation and distribution of early regional markers are ostensibly normal in Bapx1(Cre/Cre) gut, but there are distinctive morphologic abnormalities near this rostral Bapx1 domain: the antral segment of the stomach is markedly shortened, and the pyloric constriction is lost. Comparison of expression domains and examination of stomach phenotypes in single and compound Barx1 and Bapx1 mutant mice suggests a hierarchy between these 2 factors; Bapx1 expression is lost in the absence of Barx1. Conclusions: This study reveals the nonredundant requirement for Bapx1 in distal stomach development, places it within a Barx1-dependent pathway, and illustrates the pervasive influence of gut mesenchyme homeobox genes on endoderm differentiation and digestive organogenesis.

AB Background & Aim: The Notch signaling pathway is required for the expansion of undifferentiated pancreatic progenitor cells during embryonic development and has been implicated in the progression of pancreatic ductal adenocarcinoma (PDAC). The interaction of Notch ligands with their receptors promotes a gamma-secretase-dependent cleavage of the Notch receptor and release of the Notch intracellular domain, which translocates to the nucleus and activates transcription. We investigated the role of this pathway in PDAC progression. Methods: We tested the effects of a gamma-secretase inhibitor (GSI) that blocks Notch signaling in PDAC cell lines and a genetically engineered mouse model of PDAC (Kras p53 L/+ mice). Results: Notch signaling was activated in PDAC precursors and advanced tumors. The GSI inhibited the growth of premalignant pancreatic duct-derived cells in a Notch-dependent manner. Additionally, in a panel of over 400 human solid tumorderived cell lines, PDAC cells, as a group, were more sensitive to the GSI than any other tumor type. Finally, the GSI completely inhibited tumor development in the genetically engineered model of invasive PDAC (P <.005, chi(2) test; compared with mice exposed to vehicle). Conclusions: These results suggest that Notch signaling is required for PDAC progression. Pharmacologic targeting of this pathway offers therapeutic potential in this treatment-refractory malignancy.

AB The purpose of this case study was to gain an in-depth understanding of the mental, physical, and emotional burden of being infected with the hepatitis C virus (HCV) from the perspective of an individual living with the disease and undergoing antiviral treatment. Interviews were conducted during and after antiviral therapy with 1 participant chosen from a Midwest HCV clinic population. Interviews were audio recorded, transcribed verbatim, and coded. Content analysis and thematic analysis were performed. The participant reviewed and validated the themes and the interpretation of the themes. Ten categories were identified, which were subsequently integrated in 4 themes: (1) transition or process of change, (2) maintaining control over one's life, (3) social support and communication, and (4) side effects. The results of this study can assist healthcare providers to understand what individuals experience in the course of HCV infection and its treatment. This knowledge will assist them to provide effective patient-centered care. To provide such care, it is imperative that healthcare providers understand the physical, psychological, social, and professional impact that the diagnosis of HCV infection and antiviral therapy has on individuals.

AB Background: The clinical course of pancreatic endocrine tumors (PET) depends on tumor size, the presence Of invasion or metastasis, the Ki-67 index, mitose's per high power field, and mutational damage. Most of this information is not available before surgery for clinical decision making or prognostication.
Objective: To evaluate PET FUS-guided FNA (EUS-FNA) microsatellite loss analysis in the context of PET-related mortality.
Design: A single institution retrospective cohort.
Patients: Patients with PET diagnosed by EUS-FNA who underwent DNA microsatellite loss analysis and at least 1 year of follow-up or subsequent death.
Intervention: PET microsatellite loss analysis and current clinical status were compared
Results: Twenty-nine patients were included in the final analysis; the mean age of the patients was 57 years, and 10 were women (35%). The mean follow-up was 33.7 months (median 30 months, range 2-66 months). Twelve patients had disease progression, and 8 died, all from disease-specific causes. Malignant PET contained multiple microsatellite losses, with a median fractional allelic loss (FAL) of 0.37 (range 0.12-0.69, interquartile range [IQR] 0.23-0.42), significantly different from benign PET, median FAL 0 (range 0-0.18, IQR 0-0.08, P < .0001). Survival analysis revealed a significant difference in disease recurrence progression at 2 years (P < .0001) and in the 5-year survival between patients with FAL <= 0.2 compared with 0.2 (P <.0001). Logistic regression could not he performed because of the perfect association between an FAL > 0.2 of the perfect association between an FAL > 0.2 and disease status or mortality.
Limitations: Retrospective design, referral bias, and DNA analysis availability.
Conclusions: PET EUS-FNA microsatellite loss analysis provides preoperative prognostic information. An FAL > 0.2 is not only associated with disease progression but also with mortality (Gastrointest Endosc 2009:69:1074-80.)

AB Background: The role of pancreatic cyst fluid DNA analysis in evaluating cysts remains unclear.
Objective: Our purpose was to evaluate the utility of a detailed DNA analysis of pancreatic cyst fluid to diagnose mucinous and malignant cyst.
Design: Prospective, multicenter study.
Patients: Patients with pancreatic cysts presenting for EUS evaluation.
Intervention: EUS-guided pancreatic cyst aspirates cytology evaluation, carcinoembryonic antigen (CEA) level determination, and a detailed DNA analysis; incorporating DNA quantification, k-ras mutation and multiple allelic has analysis, mutational amplitude, and sequence determination.
Main Outcome Measurements: Cyst fluid analysis compared with surgical pathologic or malignant cytologic examination
Results: The study cohort consisted of 113 patients with 40 malignant, 48 premalignant, and 25 benign cyst Cyst fluid k-ras mutation was helpful in the diagnosis of mucinous cysts (odds ratio 20.9, specificity 96%), whereas receiver-operator characteristic curve analysis indicated optimal cutoff points For allelic loss amplitude (area under the curve [AUC] 0.79; optimal value > 65%) and CEA (AUC 0.74; optimal value > 148 ng/ml). Components of DNA analysis detecting malignant cysts included allelic loss amplitude over 82% (AUC 0.9) and high DNA amount (optical density ratio > 10, AUC 0.79). The criteria of a high amplitude k-ras mutation followed by allelic loss showed maximum specificity (96%) for malignancy. All malignant cysts with negative cytology evaluation (10/40) could be diagnosed as malignant by using DNA analysis.
Limitations: United follow-up, selection bias.
Conclusions: Elevated amounts of pancreatic cyst fluid DNA hi,high-amplitude mutations, Mid specific mutation acquistion sequences we indicators of malignancy. The presence of a k-ras mutation is also indicative of a mucinous cyst. DNA analysis should be considered when cyst cytologic examination is negative for malignancy.

AB Association analyses may follow an initial linkage analysis for mapping and identifying genes underlying complex quantitative traits and may be conducted on unrelated subsets of individuals where only one member of a family is included. We evaluate two methods to select one sibling per sibship when multiple siblings are available: (1) one sibling with the most extreme trait value; and (2) one sibling using a combination score statistic based on extreme trait values and identity-by-descent sharing information. We compare the type 1 error and power. Furthermore, we compare these selection strategies with a strategy that randomly selects one sibling per sibship and with an approach that includes all siblings, using both simulation Study and an application to fasting blood glucose in the Framingham Heart Study. When genetic effect is homogeneous, we find that using the combination score call increase power by 30-40% compared to a random selection strategy, and loses only 8-13% of power compared to the full sibship analysis, across all additive models considered, but offers at least 50% genotyping cost saving. In the presence of genetic heterogeneity, the score of fers a 50% increase in power over a random selection strategy, but there is substantial loss compared to the full sibship analysis. In application to fasting blood sample, two SNPs are found in common for the selection strategies and the full sample among the 10 highest ranked single nucleotide polymorphisms. The EV strategy tends to agree with the IBD-EV strategy and the analysis of the full sample. Genet. Epidemiol. 33:299-307, 2009. (C) 2008 Wiley-Liss, Inc.

AB Natural killer (NK) cells contribute to the essential functions of innate immunity and reproduction. Various genes encode NK cell receptors that recognize the major histocompatibility complex (MHC) Class I molecules expressed by other cells. For primate NK cells, the killer-cell immunoglobulin-like receptors (KIR) are a variable and rapidly evolving family of MHC Class I receptors. Studied here is KIR3DL1/S1, which encodes receptors for highly polymorphic human HLA-A and -B and comprises three ancient allelic lineages that have been preserved by balancing selection throughout human evolution. While the 3DS1 lineage of activating receptors has been conserved, the two 3DL1 lineages of inhibitory receptors were diversified through inter-lineage recombination with each other and with 3DS1. Prominent targets for recombination were D0-domain polymorphisms, which modulate enhancer function, and dimorphism at position 283 in the D2 domain, which influences inhibitory function. In African populations, unequal crossing over between the 3DL1 and 3DL2 genes produced a deleted KIR haplotype in which the telomeric "half'' was reduced to a single fusion gene with functional properties distinct from its 3DL1 and 3DL2 parents. Conversely, in Eurasian populations, duplication of the KIR3DL1/S1 locus by unequal crossing over has enabled individuals to carry and express alleles of all three KIR3DL1/S1 lineages. These results demonstrate how meiotic recombination combines with an ancient, preserved diversity to create new KIR phenotypes upon which natural selection acts. A consequence of such recombination is to blur the distinction between alleles and loci in the rapidly evolving human KIR gene family.

AB Objective. Clear cell endometrial cancer (CCE) is an uncommon but important disease because of its aggressive behavior. Furthermore, prospective, randomized studies are either too difficult or impossible because of the small number of women affected. This review explores the differences between clear cell and endometrioid endometrial cancer. In addition, it uses available evidence to determine the best approach to management.
Methods. Medline was searched between January 1, 1966 and December 31, 2008 for all publications in English where the studied population included women diagnosed with CCE. Qualifying studies must have had at least 30 patients.
Results. Clear cell histology is diagnosed in less than 6% of all endometrial cancers and its incidence increases with age. Diagnosis can be made using the same tests that are used in the diagnosis of other types of endometrial cancer. Clear cell histology is morphologically and genetically different from the more prevalent endometrioid endometrial cancer histology. It shares many similarities with clear cell neoplasms of the ovary and kidney. Comprehensive surgical staging is critical in order to plan appropriate postoperative management. Adjuvant pelvic and/or whole abdominal radiotherapy have not been shown to be clearly beneficial ill women diagnosed with clear cell endometrial cancer. Adjuvant chemotherapy with cisplatinum, taxol and doxorubicin either in a doublet or triplet combination has demonstrated efficacy.
Conclusions. Women diagnosed with CCE require comprehensive surgical staging. Platinum based adjuvant chemotherapy in a doublet or triplet format in combination with paclitaxel and/or doxorubicin should be considered as part of treatment of these women. Careful long term surveillance following treatment is indicated given the higher rate of recurrence compared to endometrioid endometrial cancer. (C) 2009 Elsevier Inc. All rights reserved.

TI Financial Penalties For The Unhealthy? Ethical Guidelines For Holding
Employees Responsible For Their Health
SO HEALTH AFFAIRS
LA English
DT Article
AB As health care costs continue to rise, an increasing number of self-insured employers are using financial rewards or penalties to promote healthy behavior and control costs. These incentive programs have triggered a backlash from those concerned that holding employees responsible for their health, particularly through the use of penalties, violates individual liberties and discriminates against the unhealthy. This paper offers an ethical analysis of employee health incentive programs and presents an argument for a set of conditions under which penalties can be used in an ethical and responsible way to contain health care costs and encourage healthy behavior among employees.

AB Objective: The aim of this study was to examine the role of active and avoidant coping strategies in predicting mortality in 61 veterans with end-stage renal disease. Design: Participants completed a self-report measure of coping strategies (The COPE; Carver, Scheier, & Weintraub, 1989) and were interviewed as part of a structured assessment to determine their appropriateness for renal transplant. On average, participants were then followed for 9 years via medical record review to determine mortality status. Main Outcome Measures: Mortality, as predicted by factor scores on active and avoidant coping factors estimated via confirmatory factor analysis of select COPE subscales. Results: A Cox regression revealed that a unit change in avoidant coping was associated with a 114% increase in odds of mortality, even after controlling for variance attributable to demographic variables. There was also a statistical trend indicating that this association might be mediated by poor attendance at medical appointments. Active coping did not predict mortality. Conclusion: Results demonstrate the importance of assessing coping style in this population; clinical implications of these findings and possible mechanisms of this effect are discussed.

AB BACKGROUND Cardiac conduction, as assessed by electrocardiographic PR interval and QRS duration, is an important electrophysiological trait and a determinant of arrhythmia risk.
OBJECTIVE We sought to identify common genetic determinants of these measures.
METHODS We examined 1604 individuals from the island of Kosrae, Federated States of Micronesia, an isolated founder population. We adjusted for covariates and estimated the heritability of quantitative electrocardiographic QRS duration and PR interval and, secondarily, its subcomponents, P-wave duration and PR segment. Finally, we performed a genome-wide association study (GWAS) in a subset of 1262 individuals genotyped using the Affymetrix GeneChip Human Mapping 500K microarray.
RESULTS The heritability of PR interval was 34% (standard error [SE] 5%, P = 4 x 10(-18)); of PR segment, 31% (SE 6%, P = 3.2 x 10(-13)); and of P-wave duration, 17% (SE 5%, P = 5.8 x 10(-6)), but the heritablitity of QRS duration was only 3% (SE 4%, P = .20). Hence, GWAS was performed only for the PR interval and its subcomponents. A total of 338,049 single nucleotide polymorphisms (SNPs) passed quality filters. For the PR interval, the most significantly associated SNPs were located in and downstream of the alpha-subunit of the cardiac voltage-gated sodium channel gene SCN5A, with a 4.8 ms (SE 1.0) or 0.23 standard deviation increase in adjusted PR interval for each minor allele copy of rs7638909 (P = 1.6 x 10(-6), minor allele frequency 0.40). These SNPs were also associated with P-wave duration (P = 1.5 x 10(-4)) and PR segment (P = .01) but not with QRS duration (P >= .22).
CONCLUSIONS The PR interval and its subcomponents showed substantial heritability in a South Pacific islander population and were associated with common genetic variation in SCN5A.

AB Recent studies suggest that long-term suppression of viral replication is critical to reducing the complications of chronic hepatitis B virus (HBV) infection. Monitoring for continued virological response during and after treatment is essential because current treatment options have limited success in achieving durable endpoints, and antiviral resistance may emerge during long-term therapy. Methods of monitoring treatment response include tests for serum aminotransferase levels, HBV DNA level, hepatitis B e antigen (HBeAg) and antibody (anti-HBe), hepatitis B surface antigen (HBsAg) or antibody (anti-HBs), and liver histology. Virological suppression and loss of HBeAg or HBsAg with or without seroconversion play a prominent role in decision-making regarding the success and duration of antiviral therapy. Guidelines recommend that testing for serum markers be repeated every 12-24 weeks during antiviral therapy and every 6-12 months afterward. Recent data also suggest that serum HBV DNA levels should be assessed at weeks 12 and 24 of therapy, because early viral response may predict the likelihood of sustained response and antiviral resistance. The use of serum HBV DNA levels for this purpose requires an assay with a wide range of quantification, such as real-time polymerase chain reaction assays, which have a 7-8 log(10) dynamic range. Newer, investigational methods for monitoring treatment response include quantitative measurement of HBsAg, HBeAg, and intrahepatic covalently closed circular DNA. Conclusions. Better methods for defining durable treatment endpoints are needed. Other areas requiring further research include the optimal treatment duration and the establishment of the optimal use of early viral kinetics for decision-making during antiviral therapy.

AB Five oral agents have been approved for the treatment of chronic hepatitis B, ranging in virological potency, clinical efficacy, barrier to resistance, and side-effect profile. The degree of histological, biochemical, and serological improvement with therapy generally corresponds to the degree of suppression of serum hepatitis B virus (HBV) DNA achieved with therapy. Conversely, for agents with a low barrier to resistance, the profundity of HBV DNA suppression in individual patients correlates inversely with the likelihood of resistance. The durability of hepatitis B e antigen (HBeAg) responses after a consolidation period of an additional 6-12 months of therapy is similar to 80% in western populations, lower in Asian populations. Loss of hepatitis B surface antigen (HBsAg) during a year of oral-agent therapy is limited, except with the most potent agents, but extending therapy for a second year and beyond can yield frequencies of HBsAg responses close to those reported in trials of interferon-based therapy. The oral agents are approved for 1-2 years of therapy, but treatment is continued indefinitely in the majority of patients (except for the similar to 20% of patients who are HBeAg-reactive who achieve a durable HBeAg response). HBeAg responses and virological/biochemical benefit continue to be maintained and to increase with continued therapy beyond the first year. Data continue to accumulate supporting the link between long-term HBV DNA suppression and reduction in hepatic fibrosis, hepatic decompensation, and liver-related mortality. All the benefits of a single year of injectable peginterferon therapy can be achieved with the newer, low-resistance oral agents continued beyond the first year, without interferon side effects. Future studies are needed to develop drug regimens that are even more effective in achieving clinical endpoints, that are not hampered by resistance, and that are more confined in treatment duration but are more durable.

AB Purpose: Challenges exist regarding antiretroviral quantitation in the female genital tract. Endocervical wicking using sterile tear flow test strips is an alternative to conventional methods due to the consistent sample volume obtained. Methods: A novel method for measuring antiretrovirals in cervicovaginal secretions using Sno-strip (R) wicking was developed and tested by spiking Sno-strips (R) with known concentrations of tenofovir, nevirapine, atazanavir, lopinavir, and ritonavir in blank cervicovaginal lavage fluid. Drug concentrations were determined by high-performance liquid chromatography with ultraviolet or mass spectrometry detection. Results: Mean extraction recoveries were 91% for tenofovir, 89% for nevirapine, 63% for atazanavir, 60% for lopinavir, and 61% for ritonavir relative to controls. Freezing spiked samples for 24 hours at -80 degrees C had no effect on recovery. Conclusions: Results suggest that the antiretrovirals tested can be efficiently extracted from Sno-strips (R), although a greater percentage of tenofovir and nevirapine was recovered. Storage of Sno-strip (R) samples up to 24 hours before analysis showed no difference in the percentage of drug recovered compared with immediate analysis. Quantitating antiretroviral penetration into the female genital tract may assist in determining optimal therapeutic antiretroviral regimens to both decrease the risk of HIV transmission and prevent development of HIV drug resistance.

AB Stimulus evoked changes in cerebral blood flow, volume, and oxygenation arise from responses to underlying neuronally mediated changes in vascular tone and cerebral oxygen metabolism. There is increasing evidence that the magnitude and temporal characteristics of these evoked hemodynamic changes are additionally influenced by the local properties of the vasculature including the levels of baseline cerebral blood flow, volume, and blood oxygenation. In this work, we utilize a physiologically motivated vascular model to describe the temporal characteristics of evoked hemodynamic responses and their expected relationships to the structural and biomechanical properties of the underlying vasculature. We use this model in a temporal curve-fitting analysis of the high-temporal resolution functional MRI data to estimate the underlying cerebral vascular and metabolic responses in the brain. We present evidence for the feasibility of our model-based analysis to estimate transient changes in the cerebral metabolic rate of oxygen (CMRO(2)) in the human motor cortex from combined pulsed arterial spin labeling (ASL) and blood oxygen level dependent (BOLD) MRI. We examine both the numerical characteristics of this model and present experimental evidence to support this model by examining concurrently measured ASL, BOLD, and near-infrared spectroscopy to validate the calculated changes in underlying CMRO(2).

AB Large case-control genome-wide association studies primarily expose common variants contributing to disease pathogenesis with modest effects. Thus, alternative strategies are needed to tackle rare, possibly more penetrant alleles. One strategy is to use special populations with a founder effect and isolation, resulting in allelic enrichment. For multiple sclerosis such a unique setting is reported in Southern Ostrobothnia in Finland, where the prevalence and familial occurrence of multiple sclerosis (MS) are exceptionally high. Here, we have studied one of the best replicated MS loci, 5p, and monitored for haplotypes shared among 72 regional MS cases, the majority of which are genealogically distantly related. The haplotype analysis over the 45 Mb region, covering the linkage peak identified in Finnish MS families, revealed only modest association at IL7R (P = 0.04), recently implicated in MS, whereas most significant association was found with one haplotype covering the C7-FLJ40243 locus (P = 0.0001), 5.1 Mb centromeric of IL7R. The finding was validated in an independent sample from the isolate and resulted in an odds ratio of 2.73 (P = 0.000003) in the combined data set. The identified relatively rare risk haplotype contains C7 (complement component 7), an important player of the innate immune system. Suggestive association with alleles of the region was seen also in more heterogeneous populations. Interestingly, also the complement activity correlated with the identified risk haplotype. These results suggest that the MS predisposing locus on 5p is more complex than assumed and exemplify power of population isolates in the identification of rare disease alleles.

AB Intraglomerular renin-angiotensin system enzyme activities have been examined previously using glomerular lysates and immune-based assays. However, preparation of glomerular extracts compromises the integrity of their anatomic architecture. In addition, antibody-based assays focus on angiotensin (Ang) II detection, ignoring the generation of other Ang I-derived metabolites, some of which may cross-react with Ang II. Therefore, our aim was to examine the metabolism of Ang I in freshly isolated intact glomeruli using matrix-assisted laser desorption ionization time of flight mass spectrometry as an analytic method. Glomeruli from male Sprague-Dawley rats were isolated by sieving and incubated in Krebs buffer in the presence of 1 mu mol/L of Ang I for 15 to 90 minutes, with or without various peptidase inhibitors. Peptide sequences were confirmed by matrix-assisted laser desorption ionization time of flight tandem mass spectrometry or linear-trap-quadrupole mass spectrometry. Peaks were quantified using customized valine-(13)C(center dot 15)N-labeled peptides as standards. The most prominent peaks resulting from Ang I cleavage were 899 and 1181 m/z, corresponding with Ang (1-7) and Ang (2-10), respectively. Smaller peaks for Ang II, Ang (1-9), and Ang (3-10) also were detected. The disappearance of Ang I was significantly reduced during inhibition of aminopeptidase A or neprilysin. In contrast, captopril did not alter Ang I degradation. Furthermore, during simultaneous inhibition of aminopeptidase A and neprilysin, the disappearance of Ang I was markedly attenuated compared with all of the other conditions. These results suggest that there is prominent intraglomerular conversion of Ang I to Ang (2-10) and Ang (1-7), mediated by aminopeptidase A and neprilysin, respectively. Formation of these alternative Ang peptides may be critical to counterbalance the local actions of Ang II. Enhancement of these enzymatic activities may constitute potential therapeutic targets for Ang II-mediated glomerular diseases. (Hypertension. 2009; 53: 790-797.)

AB We report on a CMOS RF transceiver designed for detection of biological objects such as cancer marker proteins. Its main function is to manipulate and monitor RF dynamics of protons in water via nuclear magnetic resonance (NMR). Target objects alter the proton dynamics, which is the basis for our biosensing. The RF transceiver has a measured receiver noise figure of 0.7 dB. This high sensitivity enabled construction of an entire NMR system around the RF transceiver in a 2-kg portable platform, which is 60 times lighter, 40 times smaller, yet 60 times more mass sensitive than a state-of-the-art commercial benchtop system. Sensing 20 fmol and 1.4 ng of avidin (protein) in a 5 mu L sample volume, our system represents a circuit designer's approach to pursue low-cost diagnostics in a portable platform.

AB CD160 is a newly identified ligand for HVEM (herpes virus entry mediator). Previously identified HVEM ligands include BTLA (B- and T-lymphocyte attenuator), LIGHT (lymphotoxin-like, exhibits inducible expression, and competes with herpes simplex virus glycoprotein D for HVEM, a receptor expressed by T lymphocytes) and LT alpha (lymphotoxin-alpha). The binding of LIGHT or LT alpha to HVEM delivers a costimulatory signal, whereas the binding of BTLA or CD160 to HVEM delivers a coinhibitory signal. Thus, HVEM is a bidirectional switch regulating T-cell activation in a costimulatory or coinhibitory fashion whose outcome depends on the ligand engaged. The cysteine-rich domain 1 (CRD1) of HVEM is essential for the binding of coinhibitory ligands CD160 and BTLA but not costimulatory ligand LIGHT. Deletion or blockade of HVEM CRD1 abolishes the binding of CD160 and BTLA, but not LIGHT, and converts HVEM to a dominant costimulatory molecule, possibly through the loss of negative signaling by CD160/BTLA. Therapies targeting the CRD1 of HVEM to block BTLA and CD160 binding are being developed to enhance immune responses and vaccination.

AB Substance abuse is a growing world-wide problem. The big four drugs of abuse that might lend themselves to immunotherapy are nicotine, cocaine, morphine/heroin and methamphetamine. Tobacco abuse has a well-known enormous impact on major chronic cardiovascular and pulmonary diseases, while the last three, aside from their neuropsychological effects, are illegal, leading to crime and incarceration as well as the transmission of viral diseases. Having an efficient vaccine that would generate antibodies to sequester the drug and prevent its access to the brain could go a long way toward helping a motivated addict quit the addiction. This review will discuss what has been done to bring such vaccines to human use, and what the challenges are for the future of this promising intervention.

AB Considerable effort is being made to understand the acute and memory antibody responses in natural cholera infection, while rather less is known about the roles of cellular immune responses involving T and B lymphocytes. We studied responses in adult patients hospitalized with cholera caused by Vibrio cholerae O1. Peripheral blood mononuclear cells from patients (n = 15) were analyzed by flow cytometry after stimulation with V. cholerae O1 membrane protein (MP) or toxin-coregulated pilus antigen (TcpA). The gamma interferon (IFN-gamma) and interleukin-13 (IL-13) responses in stimulated-lymphocyte supernatants were studied. The responses were compared with those of healthy controls (n = 10). Patients responded with increased frequencies of gut-homing CD4(+) T cells (CD4(+) beta 7(+)), gut-homing CD8(+) T cells (CD8(+) beta 7(+)), and gut-homing B cells (CD19(+) beta 7(+)) at the early and/or late convalescent stages compared to the acute stage. After stimulation with MP or TcpA, proliferation of CD4(+) and CD8(+) T cells was increased at the acute stage and/or early convalescent stage compared to healthy controls. Increased IL-13 and IFN-gamma responses were observed after antigenic stimulation at the acute and convalescent stages compared to healthy controls. Thus, increases in the levels of gut-homing T and B cells, as well as involvement of CD8 and CD4 Th1-mediated (IFN-gamma) and CD4 Th2-mediated (IL-13) cytokine responses, take place in acute dehydrating disease caused by V. cholerae O1. Further studies are needed to determine if such responses are also stimulated after immunization with oral cholera vaccines and if these responses play a role in protection following exposure to cholera.

AB The objective of the study was to evaluate the response of generalized anxiety disorder (GAD) patients with prominent gastrointestinal (GO symptoms to pregabalin (PGB) treatment. Data were pooled from six double-blind, placebo (PBO)-controlled, 4-6 week trials in outpatients who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition criteria for GAD with a minimum Hamilton Anxiety Rating Scale (HAM-A) total score of 20. Treatment response was evaluated for three PGB fixed-dosage groups: 150, 300-450, and 600 mg/day, and for fixed doses of a benzodiazepine (alprazolam, 1.5 mg/day; lorazepam, 6 mg/day). A GI-high subgroup (high GI symptomatology) was defined by a baseline HAM-A item-11 (G 1) score of 3 or greater (severe/very severe). At baseline, 301 patients (16.2%) met criteria for the GI-high subgroup. Baseline characteristics were approximately similar for the four study treatments in the GI-high subgroup. For the GI-high subgroup, last observation carried forward (LOCF) endpoint reduction in HAM-A was significantly higher on PGB-300/450-13.8 +/- 1.2 and PGB-600 - 14.7 +/- 1.0 compared with PBO - 10.1 +/- 0.9 (P< 0.01 for both comparisons); but the difference on PGB-150 did not achieve significance (- 13.5 +/- 11.6; P=0.083). Also in the GI-high subgroup, endpoint reduction in HAM-A item-11 was significantly higher on PGB-300/450 compared with PBO (- 1.93 +/- 0.16 vs. - 1.52 +/- 0.13; P= 0.04), but did not achieve significance on PG B-600 mg (- 1.89 +/- 0.14; P= 0.06), or PG B-150 mg (- 1.90 +/- 0.23; P= 0.16). In the GI-high subgroup, treatment with a benzodiazepine was not associated with significant endpoint reduction in either the HAM-A total score or the HAM-A item-11 score. Patients in the GI-high subgroup had higher discontinuation rates when treated with benzodiazepines, whereas treatment with PGB 300-600 mg/day was not associated with treatment-emergent worsening in GI symptoms compared with placebo. Treatment with PGB improved overall levels of anxiety, as well as specifically improving GI symptoms.

AB Micro-RNAs are a group of small noncoding RNAs approximately 22 nucleotides in length. Recent work has shown differential expression of mature micro-RNAs in human cancers. We characterized the alteration in expression of miR-29b in ovarian serous carcinoma. miR-29b expression was analyzed using quantitative stem-loop reverse transcriptase polymerase chain reaction on a set of 50 formal in-fixed, paraffin-embedded ovarian serous carcinoma samples. Protein expression of p53, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, Ki-67, and insulinlike growth factor I was quantified in the corresponding tissue microarray. The expression profile of miR-29b was correlated with clinicopathological and patient survival data. We provide definitive evidence that miR-29b is down-regulated in a significant proportion of ovarian serous carcinomas and is associated with specific clinicopathological features, most notably high miR-29b expression being associated with reduced disease-free survival.

AB The purpose of this study was to investigate the large-scale characteristic molecular signature of Mullerian inhibiting substance (MIS) in human ovarian cancer cells through expression genomics. To understand the comprehensive molecular mechanisms by which MIS inhibits ovarian cancer cell growth, we identified the large-scale characteristic molecular changes elicited by MIS in the human ovarian cancer cell line OVCAR-8, using DNA microarray analysis. Combined serial gene expression analysis from 0 to 96 h after MIS treatment of OVCAR-8 cells resulted in 759 genes which showed at least a 2-fold change in overexpression or underexpression compared to non-treatment groups. Of the 759 outlier genes, 498 genes were mapped to known biological cellular processes, and the resultant major pathways included metabolism, signal transduction, cell growth and apoptosis. Among these pathways, 68 genetic elements were dissected as cell cycle-related genes induced by MIS. Although cellular phenotypic changes by MIS were observed after 24 h of treatment, the characteristic large-scale molecular changes were observed from 48 to 96 h of exposure to MIS. This finding may imply that the suppressive role of MIS on ovarian cancer cells could be cumulative in that the metabolic disturbance of MIS is followed by arrest at the G1/S cell cycle checkpoint. We suggest 759 outlier genes comprise the characteristic molecular signature of MIS, which may be responsible for the suppressive effect on OVCAR-8 cells. Although the precise biological mechanisms underlying these outlier genes should be validated, the genetic elements described herein provide promising therapeutic interventions for ovarian cancer.

AB Attrition rates are high during treatment for major depressive disorder (MDD), and patients who drop out are less likely to reach remission. This report evaluates the incidence, timing, and predictors of attrition during second-step medication treatment. Outpatients in the multisite Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study receiving a medication augmentation (n=563) or medication switch (n=723) for non-psychotic MDD after an unsatisfactory outcome with citalopram were evaluated to determine attrition rates and pretreatment sociodemographic or clinical predictors of attrition. Twenty percent of participants receiving a medication augmentation and 27% receiving a medication switch dropped Out before 12 wk in the second treatment step. Remission rates were lower for dropouts [7% vs. 43%, (medication augmentation); 12% vs. 31% (medication switch)]. For medication augmentation, Black and other non-Caucasian races, Hispanic ethnicity, younger age, family history of drug abuse, concurrent drug abuse, sociodemographic disadvantage, less symptom improvement with initial citalopram treatment, and greater symptom severity when beginning augmentation were associated with attrition. For medication switch, Black and other non-Caucasian races, younger age, more melancholic features, and lower exit doses but more severe side-effects with citalopram treatment were associated with attrition. Minority status, younger age, and greater difficulty with the first treatment step are risk factors for attrition in the second treatment step. Focus on patients with attrition risk factors for medication augmentation or switch strategies may enhance retention and improve outcomes.

AB Background: Cut points for defining obesity have been derived from mortality data among Whites from Europe and the United States and their accuracy to screen for high risk of coronary heart disease (CHD) in other ethnic groups has been questioned.
Objective: To compare the accuracy and to define ethnic and gender-specific optimal cut points for body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) when they are used in screening for high risk of CHD in the Latin-American and the US populations.
Methods: We estimated the accuracy and optimal cut points for BMI, WC and WHR to screen for CHD risk in Latin Americans (n = 18 976), non-Hispanic Whites (Whites; n = 8956), non-Hispanic Blacks (Blacks; n 5205) and Hispanics (n = 5803). High risk of CHD was defined as a 10-year risk >= 20% (Framingham equation). The area under the receiver operator characteristic curve (AUC) and the misclassification-cost term were used to assess accuracy and to identify optimal cut points.
Results: WHR had the highest AUC in all ethnic groups (from 0.75 to 0.82) and BMI had the lowest (from 0.50 to 0.59). Optimal cut point for BMI was similar across ethnic/gender groups (27 kg/m(2)). In women, cut points for WC (94 cm) and WHR (0.91) were consistent by ethnicity. In men, cut points for WC and WHR varied significantly with ethnicity: from 91cm in Latin Americans to 102cm in Whites, and from 0.94 in Latin Americans to 0.99 in Hispanics, respectively.
Conclusion: WHR is the most accurate anthropometric indicator to screen for high risk of CHD, whereas BMI is almost uninformative. The same BMI cut point should be used in all men and women. Unique cut points for WC and WHR should be used in all women, but ethnic-specific cut points seem warranted among men.

AB Knowledge of the colonization patterns and composition of the oral microbiota can lead to a better understanding of disease initiation.
The aim of this study was to examine the distribution of selected cariogenic bacteria in samples from five different oral habitats in young Greek children.
Ninety-three children 3-12 years old (mean + SD 7.9 +/- 2.5) (60.2% male, 39.8% female) participated and split into three different age groups: primary (3-6 years), early mixed (6-9 years), and mixed dentition (9-12 years). Samples for bacterial enumeration were taken from saliva, supragingival and subgingival plaque, tongue dorsum, and soft tissues from each child, and were further analysed using checkerboard DNA-DNA hybridization.
Mean counts and proportions of all the test bacteria differed significantly among sample locations. Cariogenic bacteria were present in almost all healthy children. Mean proportions of Streptococcus mutans isolated from soft tissue and Streptococcus sanguinis from soft tissue, subgingival and saliva samples increased significantly with age, whereas the opposite was seen for Lactobacillus acidophilus.
Cariogenic bacteria were present in almost all young children. Soft tissues, saliva, and tongue were more often colonized by cariogenic streptococcal species than teeth. These surfaces may serve as reservoirs for oral pathogens, requiring attention during preventive interventions.

AB Purpose: The "Roach formula" for the risk of pelvic lymph node metastases [(2/3) * PSA + (Gleason score - 6) * 10] was developed in the early prostate-specific antigen (PSA) era. We examined the accuracy of this formula in contemporary patients.
Methods: We included men in the Surveillance, Epidemiology, and End Results Registry with a diagnosis of clinical T1c-T4 prostate cancer in 2004 who had a surgical lymph node evaluation, Gleason score (typically from prostatectomy), and baseline PSA level (n = 9,387). Expected and observed rates of node positivity were compared.
Results: Ninety-eight percent were clinical T1c/T2, and 97% underwent prostatectomy. Overall, 309 patients (3.291%) had positive lymph nodes. Roach scores overestimated the actual rate of positive lymph nodes in the derivation set by 16-fold for patients with Roach score less than or equal to 10%, by 7-fold for scores greater than 10-20%, and by approximately 2.5-fold for scores greater than 20%. Applying these adjustment factors to Roach scores in the validation data set yielded accurate predictions of risk. For those with Roach score less than or equal to 10%, adjusted expected risk was 0.2% and observed risk was 0.2%. For Roach score greater than 10-20%, adjusted expected risk was 2.0% and observed risk was 2.1%. For Roach score greater than 20-30%, adjusted expected risk was 9.7% and observed risk was 6.5%. For Roach score greater than 30-40%, adjusted expected risk was 13.9% and observed risk was 13.9%.
Conclusion: Applied to contemporary patients with mainly T1c/T2 disease, the Roach formula appears to overestimate pelvic lymph node risk. The adjustment factors presented here should be validated by using biopsy Gleason scores and extended lymphadenectomies. (C) 2009 Elsevier Inc.

AB Purpose: We compared tumor and normal tissue dosimetry of proton radiation therapy with intensity-modulated radiation therapy (IMRT) for pediatric parameningeal rhabdomyosarcomas (PRMS).
Methods and Materials: To quantify dosimetric differences between contemporary proton and photon treatment for pediatric PRMS, proton beam plans were compared with IMRT plans. Ten patients treated with proton radiation therapy at Massachusetts General Hospital had IMRT plans generated. To facilitate dosimetric comparisons, clinical target volumes and normal tissue volumes were held constant. Plans were optimized for target volume coverage and normal tissue sparing.
Results: Proton and IMRT plans provided acceptable and comparable target volume coverage, with at least 99% of the CTV receiving 95% of the prescribed dose in all cases. Improved dose conformality provided by proton therapy resulted in significant sparing of all examined normal tissues except for ipsilateral cochlea and mastoid; ipsilateral parotid gland sparing was of borderline statistical significance (p = 0.05). More profound sparing of contralateral structures by protons resulted in greater dose asymmetry between ipsilateral and contralateral retina, optic nerves, cochlea, and mastoids; dose asymmetry between ipsilateral and contralateral parotids was of borderline statistical significance (p = 0.05).
Conclusions: For pediatric PRMS, superior normal tissue sparing is achieved with proton radiation therapy compared with IMRT. Because of enhanced conformality, proton plans also demonstrate greater normal tissue dose distribution asymmetry. Longitudinal studies assessing the impact of proton radiotherapy and IMRT on normal tissue function and growth symmetry are necessary to define the clinical consequences of these differences.

AB Purpose: To evaluate the respiratory motion of primary esophageal cancers and pathologic celiac-region lymph nodes using time-resolved four-dimensional computed tomography (4D CT).
Methods and Materials: Respiration-synchronized 41) CT scans were obtained to quantify the motion of primary tumors located in the proximal, mid-, or distal thoracic esophagus, as well as any involved celiac-region lymph nodes. Respiratory motion was measured in the superior-inferior (SI), anterior-posterior (AP), and left-right (LR) directions and was analyzed for correlation with anatomic location. Recommended margin expansions were determined for both primary and nodal targets.
Results: Thirty patients underwent 4D CT scans at Massachusetts General Hospital for planned curative treatment of esophageal cancer. Measurements of respiratory tumor motion were obtained for I proximal, 4 mid-, and 25 distal esophageal tumors, as well as 12 involved celiac-region lymph nodes. The mean (SD) peak-to-peak displacements of all primary tumors in the SI, AP, and LR dimensions were 0.80 (0.45) cm, 0.28 (0.20) cm, and 0.22 (0.23) cm, respectively. Distal tumors were found to have significantly greater SI and AP motion than proximal or mid-esophageal tumors. The mean (SD) SI, AP, and LR peak-to-peak displacements of the celiac-region lymph nodes were 0.92 (0.56) cm, 0.46 (0.27) cm, and 0.19 (0.26) cm, respectively.
Conclusions: Margins of 1.5 cm SI, 0.75 cm AP, and 0.75 cm LR would account for respiratory tumor motion of >95% of esophageal primary tumors in the dataset. All celiac-region lymph nodes would be adequately covered with SI, AP, and LR margins of 2.25 cm, 1.0 cm, and 0.75 cm, respectively. (C) 2009 Elsevier Inc.

AB Four strains of anaerobic, Gram-negative bacilli isolated from the human oral cavity were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise a homogeneous group distinct from any species with validly published names. 16S rRNA and 23S rRNA gene sequence analyses and DNA-DNA reassociation data revealed that the strains constituted a novel group within the phylum 'Synergistetes' and were most closely related to Jonquetella anthropi. Two libraries of randomly cloned DNA were prepared from strain W5455(T) and were sequenced to provide a genome survey as a resource for metagenomic studies. A new genus and novel species, Pyramidobacter piscolens gen. nov., sp. nov., is proposed to accommodate these strains. The genus Pyramidobacter comprises strains that are anaerobic, non-motile, asaccharolytic bacilli that produce acetic and isovaleric acids and minor to trace amounts of propionic, isobutyric, succinic and phenylacetic acids as end products of metabolism. P. piscolens gen. nov., sp. nov. produced hydrogen sulphide but was otherwise largely biochemically unreactive. Growth was stimulated by the addition of glycine to broth media. The G + C content of the DNA of the type strain was 59 mol%. The type strain of Pyramidobacter piscolens sp. nov. is W5455(T) (=DSM 21147(T)=CCUG 55836(T)).

AB PURPOSE. The joint effects of genetic, ocular, and environmental variables were evaluated and predictive models for prevalence and incidence of AMD were assessed.
METHODS. Participants in the multicenter Age-Related Eye Disease Study (AREDS) were included in a prospective evaluation of 1446 individuals, of which 279 progressed to advanced AMD (geographic atrophy or neovascular disease) and 1167 did not progress during 6.3 years of follow-up. For prevalent AMD, 509 advanced cases were compared with 222 controls. Covariates for the incidence analysis included age, sex, education, smoking, body mass index (BMI), baseline AMD grade, and the AREDS vitamin-mineral treatment assignment. DNA specimens were evaluated for six variants in five genes related to AMD. Unconditional logistic regression analyses were performed for prevalent and incident advanced AMD. An algorithm was developed and receiver operating characteristic curves and C statistics were calculated to assess the predictive ability of risk scores to discriminate progressors from nonprogressors.
RESULTS. All genetic polymorphisms were independently related to prevalence of advanced AMD, controlling for genetic factors, smoking, BMI, and AREDS treatment. Multivariate odds ratios (ORs) were 3.5 (95% confidence interval [CI], 1.7-7.1) for CFH Y402H; 3.7 (95% CI, 1.6-8.4) for CFH rs1410996; 25.4 (95% CI, 8.6-75.1) for LOC387715 A69S (ARMS2); 0.3 (95% CI, 0.1-0.7) for C2 E318D; 0.3 (95% CI, 0.1-0.5) for CFB; and 3.6 (95% CI, 1.4-9.4) for C3 R102G, comparing the homozygous risk/protective genotypes to the referent genotypes. For incident AMD, all these variants except CFB were significantly related to progression to advanced AMD, after controlling for baseline AMD grade and other factors, with ORs from 1.8 to 4.0 for presence of two risk alleles and 0.4 for the protective allele. An interaction was seen between CFH402H and treatment, after controlling for all genotypes. Smoking was independently related to AMD, with a multiplicative joint effect with genotype on AMD risk. The C statistic for the full model with all variables was 0.831 for progression to advanced AMD.
CONCLUSIONS. Factors reflective of nature and nurture are independently related to prevalence and incidence of advanced AMD, with excellent predictive power. (Invest Ophthalmol Vis Sci. 2009;50:2044-2053) DOI:10.1167/iovs.08-3064

AB Objective: Utilizing a heterogenous sample of adults diagnosed with HIV infection, the current study sought to explore associations among age, various dimensions of social support, and psychological and functional well-being.
Methods: Cross-sectional data capturing subjective and instrumental support, social interaction, behavioral health service utilization, and psychological well-being (ie, positive affect and depressive symptomatology), and physical functioning, wet e collected from 109 men and women living with HIV To explore a;e group differences, participants were stratified by age (<54 vs. 55- years).
Results: Despite endorsing greater medical comorbidity, older adults reported significantly lower depressive symptomatology and greater positive affect and were less likely to report seeing a behavioral health specialist than their younger counterparts. No age group differences emerged for instrumental support or amount of social interaction. However, older adults reported higher subjective Support, which in turn was associated with lower depressive symptomatology, greater positive affect, and nonutilization of behavioral health services.
Conclusions: More attention should be paid to the social environment of individuals diagnosed with HIV as tic quality of social relationships may be particularly important for successful psychological adaptation to HIV

AB To examine the feasibility of subretinal delivery of immunoglobulin G (IgG) adsorbed onto gold nanoparticles (GNPs) and its histologic distribution in the rabbit retina after the injection.
Goat IgG was adsorbed onto GNPs electrostatically. Goat IgG-adsorbed GNPs or buffer with goat IgG was injected into the subretinal space of rabbit eyes and followed up for 3 months by examination of fundus photographs, immunohistochemistry against goat IgG, and transmission electron microscopy (TEM). Human retinal pigment epithelial cells (ARPE-19 cells) were cultured, and cell proliferation with or without GNPs was assayed.
At 1 week after the subretinal injection of goat IgG-adsorbed GNPs, retinal degeneration was observed in the outer retina, and goat IgG was immunolabeled in the retinal pigment epithelium (RPE) and the photoreceptor cells. TEM showed GNPs located in the outer segments and in the lysosomes in the RPE at 1 month and no apparent cytotoxicity of the RPE. There were no inhibitory effects of GNPs on proliferation of ARPE-19 cells.
Goat IgG was successfully delivered into photoreceptor cells and RPE using GNPs, though retinal degeneration in the outer retina occurred in this model. This might be an alternative drug delivery method to photoreceptors and RPE.

NEURAL MECHANISMS
AB Origins of impaired adaptive functioning in schizophrenia remain poorly understood. Behavioral disorganization may arise from an abnormal reliance on common combinations between concepts stored in semantic memory. Avolition-apathy may be related to deficits in using goal-related requirements to flexibly plan behavior. The authors recorded event-related potentials (ERPs) in 16 patients with medicated schizophrenia and 16 healthy controls in a novel video paradigm presenting congruous or incongruous objects in real-world activities. All incongruous objects were contextually inappropriate, but the incongruous scenes varied in comprehensibility. Psychopathology was assessed with the Scales for the Assessment of Positive and Negative Symptoms (SAPS/SANS) and the Brief Psychiatric Rating Scale. In patients, an N400 ERP, thought to index activity in semantic memory, was abnormally enhanced to less comprehensible incongruous scenes, and larger N400 priming was associated with disorganization severity. A P600 ERP, which may index flexible object-action integration based on goal-related requirements, was abnormally attenuated in patients, and its smaller magnitude was associated with the SANS rating of impersistence at work or school (goal-directed behavior). Thus, distinct neurocognitive abnormalities may underlie disorganization and goal-directed behavior deficits in schizophrenia.

AB Background: Suicidal behavior has been recognized as an increasing problem among alcohol-dependent subjects. The aim of the study was to identify correlates of impulsive and non-impulsive suicide attempts among a treated population of alcohol-dependent patients.
Methods: A total of 154 patients with alcohol dependence consecutively admitted for addiction treatment participated in the study. Suicidal behavior was assessed together with severity of alcohol dependence, childhood abuse, impulsivity, and family history. A stop-signal procedure was used as a behavioral measure of impulsivity.
Results and conclusions: Lifetime suicide attempts were reported by 43% of patients in alcohol treatment; of which 62% were impulsive. Compared to patients without a suicide attempt, those with a non-impulsive attempt were more likely to have a history of sexual abuse (OR=7.17), a family history of suicide (OR=4.09), and higher scores on a personality measure of impulsiveness (OR=2.27). The only significant factor that distinguished patients with impulsive suicide attempts from patients without a suicide attempt and from patients with a non-impulsive suicide attempt was a higher level of behavioral impulsivity (OR=1.84-2.42).
Limitations: Retrospective self-report of suicide attempts and family history. Lack of diagnostic measure. (C) 2008 Elsevier B.V. All rights reserved.

AB Experimental animal studies have demonstrated that exposure to some phthalates may be associated with altered endocrine function and adverse effects on male reproductive development and function, but human studies are limited. In the present study, urine and serum samples were collected from 425 men recruited through a US infertility clinic. Urinary concentrations of mono(2-ethylhexyl) phthalate (MEHP), the hydrolytic metabolite of di(2-ethylhexyl) phthalate (DEHP), and other phthalate monoester metabolites were measured, along with serum levels of testosterone, estradiol, sex hormone-binding globulin (SHBG), follicle-stimulating hormone, luteinizing hormone, inhibin B, and prolactin. Two oxidized urinary metabolites of DEHP were also measured in urine from 221 of the men. In multiple regression models adjusted for potential confounders, MEHP was inversely associated with testosterone, estradiol, and free androgen index (FAI). An interquartile range increase in MEHP was associated with 3.7% (95% confidence interval [CI], -6.8% to -0.5%) and 6.8% (95% Cl, -11.2% to -2.4%) declines in testosterone and estradiol, respectively, relative to the population median hormone levels. There was limited evidence for effect modification of the inverse association between MEHP and FAI by the proportion of DEHP metabolites in the urine measured as MEHP (MEHP%), which is considered a phenotypic marker of less efficient metabolism of DEHP to its oxidized metabolites. Finally, the ratio of testosterone to estradiol was positively associated with MEHP (P = .07) and MEHP% (P = .007), suggesting potential relationships with aromatase suppression. In conclusion, these results suggest that urinary metabolites of DEHP are inversely associated with circulating steroid hormone levels in adult men. However, additional research is needed to confirm these findings.

AB We have evaluated a Xenopus cell line as a potential sensor for detecting toxins in water. X. laevis melanophores responded rapidly by dispersing melanosomes following exposure to six (ammonia, arsenic, copper, mercury, pentachlorophenol and phenol) of 12 tested chemicals in the desired sensitivity range. For two additional chemicals (nicotine and paraquat) the melanophore response improved upon the response capabilities of several available toxicity sensors. These results suggest that a melanophore-based sensor could be useful for the rapid assessment of chemical toxicity in drinking water. Published 2009 by John Wiley and Sons, Ltd.

AB Fc gamma RIIB is an inhibitory receptor which plays a role in limiting B cell and DC activation. Since Fc gamma RIIB is known to dampen the signaling strength of the BCR, vie wished to determine the impact of Fc gamma RIIB on the regulation of BCRs which differ in their affinity for DNA. For these studies, Fc gamma RIIB deficient BALB/c mice were bred with mice expressing the transgene-encoded H chain of the R4A anti-DNA antibody which gives rise to BCRs which express high, low or no affinity for DNA. The deletion of Fc gamma RIIB in R4A BALB/c mice led to an alteration in the B cell repertoire, allowing for the expansion and activation of high affinity DNA-reactive B cells. By 6-8 months of age, R4A x Fc gamma RIIB(-/-) BALB/c mice spontaneously developed anti-DNA antibody titers. These mice also displayed an induction of IFN-inducible genes and an elevation in levels of the B cell survival factor, BAFF. These data demonstrate that Fc gamma RIIB preferentially limits activation of high affinity autoreactive B cells and can influence the activation of DC through an immune complex-mediated mechanism.

AB Insulin signaling is essential for normal glucose homeostasis. Rho-kinase (ROCK) isoforms have been shown to participate in insulin signaling and glucose metabolism in cultured cell lines. To investigate the physiological role of ROCK1 in the regulation of whole body glucose homeostasis and insulin sensitivity in vivo, we studied mice with global disruption of ROCK1. Here we show that, at 16 - 18 weeks of age, ROCK1-deficient mice exhibited insulin resistance, as revealed by the failure of blood glucose levels to decrease after insulin injection. However, glucose tolerance was normal in the absence of ROCK1. These effects were independent of changes in adiposity. Interestingly, ROCK1 gene ablation caused a significant increase in glucose-induced insulin secretion, leading to hyperinsulinemia. To determine the mechanism(s) by which deletion of ROCK1 causes insulin resistance, we measured the ability of insulin to activate phosphatidylinositol 3-kinase and multiple distal pathways in skeletal muscle. Insulin-stimulated phosphatidylinositol 3-kinase activity associated with IRS-1 or phospho-tyrosine was also reduced similar to 40% without any alteration in tyrosine phosphorylation of insulin receptor in skeletal muscle. Concurrently, serine phosphorylation of IRS-1 at serine 632/635, which is phosphorylated by ROCK in vitro, was also impaired in these mice. Insulin-induced phosphorylation of Akt, AS160, S6K, and S6 was also decreased in skeletal muscle. These data suggest that ROCK1 deficiency causes systemic insulin resistance by impairing insulin signaling in skeletal muscle. Thus, our results identify ROCK1 as a novel regulator of glucose homeostasis and insulin sensitivity in vivo, which could lead to new treatment approaches for obesity and type 2 diabetes.

AB Sputtered iridium (oxide films (SIROFs) deposited by DC reactive sputtering from an iridium metal target have been characterized in vitro for their potential as neural recording and stimulation electrodes. SIROFs were deposited over gold metallization oil flexible multielectrode arrays fabricated oil thin (15 mu m) polyimide substrates. SIROF thickness and electrode areas of 200-1300 nm and 1960-125,600 mu m(2), respectively, were investigated. The charge-injection capacities of the SIROFs were evaluated in an inorganic interstitial fluid model in response to charge-balanced, cathodal-first current pulses. Charge injection capacities were measured as a function of cathodal pulse width (0.2-1 ins) and potential bias in the interpulse period (0.0 to 0.7 V vs. Ag/AgCl). Depending on the pulse parameters and electrode area, charge-injection capacities ranged from 1-9 mC/cm(2), comparable with activated iridium oxide films (AIROFs) pulsed under similar conditions. Other parameters relevant to the use of SIROF oil nerve electrodes, including the thickness dependence of impedance (0.05-10(5) Hz) and the current necessary to maintain a bias in the interpulse region were also determined.

AB Current methodologies for characterizing tympanic membrane (TM) motion are usually limited to either average acoustic estimates (admittance or reflectance) or single-point mobility measurements, neither of which suffices to characterize the detailed mechanical response of the TM to sound. Furthermore, while acoustic and single-point measurements may aid in diagnosing some middle-ear disorders, they are not always useful. Measurements of the motion of the entire TM surface can provide more information than these other techniques and may be superior for diagnosing pathology. We present advances in our development of a new compact optoelectronic holographic otoscope (OEHO) system for full field-of-view characterization of nanometer-scale sound-induced displacements of the TM surface at video rates. The OEHO system consists of a fiber optic subsystem, a compact otoscope head, and a high-speed image processing computer with advanced software for recording and processing holographic images coupled to a computer-controlled sound-stimulation and recording system. A prototype OEHO system is in use in a medical research environment to address basic science questions regarding TM function. The prototype provides real-time observation of sound-induced TM displacement patterns over a broad frequency range. Representative time-averaged and stroboscopic holographic interferometry results in animals and human cadaver samples are shown, and their potential utility is discussed.

We demonstrate the performance of normalized dual-wavelength measurements that are essential for in-vivo use, as they account for the heterogeneous distribution of photons in tissue. In-vivo imaging is then showcased on mouse lung and brain tumors cross-validated by x-ray microcomputed tomography and histology. (C) 2009 Society of Photo-Optical Instrumentation Engineers.

AB Bone resorption relies on the extracellular acidification function of vacuolar (V-) ATPase proton pump(s) present in the plasma membrane of osteoclasts. The exact configuration of osteoclast-specific V-ATPases remains largely unknown. In this study, we found that Atp6v0d2 (d2), an isoform of the d subunit in the V-ATPase, showed 5-fold higher expression than that of Atp6v0d1. (d1) in mature osteoclasts, indicating a potential function in osteoclastic bone resorption. When d2 was depleted at an earl), stage of RANKL-induced osteoclast differentiation in vitro, formation of multinucleated cells was severely impaired. However, depletion of d2 at a late differentiation stage did not affect osteoclast fusion but did abolish the activity of extracellular acidification and bone resorption of mature osteoclasts. We also showed the association of the two tagged-proteins d2 and a3 when co-expressed in mammalian cells with a co-immunoprecipitation assay. Moreover, glutathione-S-transferase (GST) pull-down assay showed the direct interaction of d2 with the N terminus of Atp6v0a3 (0), which is the functionally identified osteoclast-specific component of V-ATPase. Therefore, our results show the dual function of d2 as a regulator of cell fusion in osteoclast differentiation and as an essential component of the osteoclast-specific proton pump that mediates extracellular acidification in bone resorption.

AB Toxic epidermal necrolysis is a rare acute inflammatory multisystem life-threatening condition characterized by widespread epidermal necrosis and profound toxic systemic reaction. Implicated etiologic agents in children include drugs, infections, and autoimmune diseases. The pathophysiology includes separation of the epidermis at the dermal-epidermal junction of both skin and extracutaneous epithelium and mucous membranes. The general consensus is that expeditious transfer to a burn center, maintenance of fluid and electrolyte: balance, temperature maintenance, control of evaporative losses, avoidance of use of complicating drugs as corticosteroids and topical sulfa compounds, aggressive septic surveillance, vigorous nutritional support via nasoenteric tube, early ophthalmologic consultation, and appropriate wound care with a regimen of therapy relying on basic principles of treatment of partial-thickness epidermal wounds predict better outcome in the treatment of this disease process. The course of toxic epidermal necrolysis in children, even though dramatic at onset, leads to low mortality when managed appropriately. The current limited published evidence does not clearly delineate differences in epidemiology, pathogenesis, and prognosis of severe skin reactions in children as compared with adults. In this article, we review the available literature oil the pathogenesis, clinical features, pathophysiology, treatment, and complications of this rare disease in children.

AB A 40-year-old woman presented with an unusual form of corneal herpetic reactivation 5 weeks after laser in situ keratomileusis. The cornea showed diffuse edema and a stromal ring infiltrate (disciform in appearance). Oral antiviral and topical steroids in tapered dosages were administered. The infiltrate disappeared within 6 weeks. Progressive improvement was also seen in all the parameters on Pentacam scans, including the pachymetry, keratometry readings, and elevation on the anterior float. Herpetic reactivation may occur in many forms after excimer laser ablation. Timely diagnosis and management is crucial to maintain good structural and visual outcomes.

AB Oxidative stress plays a critical role in the progression of pathological cardiac hypertrophy and heart failure. Because crocetin represses oxidative stress in vitro and in vivo, we have suggested that crocetin would repress cardiac hypertrophy by targeting oxidative stress-dependent signalling. We tested this hypothesis using primary cultured cardiac myocytes and fibroblasts and one well-established animal model of cardiac hypertrophy. The results showed that crocetin (1-10 mu M) dose-dependently blocked cardiac hypertrophy induced by angiogensin II (Ang II; 1 mu M) in vitro. Our data further revealed that crocetin (50 mg/kg/day) both prevented and reversed cardiac hypertrophy induced by aortic banding (AB), as assessed by heart weight/body weight and lung weight/body weight ratios, echocardiographic parameters and gene expression of hypertrophic markers. The inhibitory effect of crocetin on cardiac hypertrophy is mediated by blocking the reactive oxygen species (ROS)-dependent mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase-1/2 (MEK/ERK1/2) pathway and GATA binding protein 4 (GATA-4) activation. Further investigation demonstrated that crocetin inhibited inflammation by blocking nuclear factor kappa B (NF-kappa B) signalling and attenuated fibrosis and collagen synthesis by abrogating MEK-ERK1/2 signalling. Overall, our results indicate that crocetin, which is a potentially safe and inexpensive therapy for clinical use, has protective potential in targeting cardiac hypertrophy and fibrosis by suppression of ROS-dependent signalling pathways.

AB Mucolipidosis type IV (MLIV) is a lysosomal storage disorder caused by mutations in the MCOLN1 gene, a member of the transient receptor potential (TRP) cation channel gene family. The encoded protein, transient receptor potential mucolipin-1 (TRPML1), has been localized to lysosomes and late endosomes but the pathogenic mechanism by which loss of TRPML1 leads to abnormal cellular storage and neuronal cell death is still poorly understood. Yeast two-hybrid and co-immunoprecipitation (coIP) experiments identified interactions between TRPML1 and Hsc70 as well as TRPML1 and Hsp40. Hsc70 and Hsp40 are members of a molecular chaperone complex required for protein transport into the lysosome during chaperone-mediated autophagy (CMA). To determine the functional relevance of this interaction, we compared fibroblasts from MLIV patients to those from sex- and age-matched controls and show a defect in CMA in response to serum withdrawal. This defect in CMA was subsequently confirmed in purified lysosomes isolated from control and MLIV fibroblasts. We further show that the amount of lysosomal-associated membrane protein type 2A (LAMP-2A) is reduced in lysosomal membranes of MLIV fibroblasts. As a result of decreased CMA, MLIV fibroblasts have increased levels of oxidized proteins compared to control fibroblasts. We hypothesize that TRPML1 may act as a docking site for intralysosomal Hsc70 (Iy-Hsc70) allowing it to more efficiently pull in substrates for CMA. It is also possible that TRPML1 channel activity may be required for CMA. Understanding the role of TRPML1 in CMA will undoubtedly help to characterize the pathogenesis of MLIV.

TI Lack of Lymphatic Vessel Phenotype in LYVE-1/CD44 Double Knockout Mice

AB Lymphatic vessels play a key role in maintaining tissue-fluid homeostasis, immune surveillance and metastasis. The hyaluronan receptor, LYVE-1, is widely used as a molecular marker for adult and embryonic lymphatic endothelium, but its physiological functions have not yet been established in vivo. In agreement with a recent report, LYVE-1(-/-) mice, which are healthy and fertile, do not display any defects related to congenital abnormalities of the lymphatic system. One hypothesis for the absence of a phenotype in LYVE-1 null mice is that other hyaluronan receptors, such as CD44, may compensate for LYVE-1. To test this hypothesis, we created LYVE-1/CD44 double knockout mice with appropriate littermate controls. Lymphatic vessel structure and function, as determined by histological methods and intravital microscopy, show that LYVE-1(-/-), CD44(-/-) and LYVE-1(-/-)/CD44(-/-) mice are indistinguishable from wild-type mice under normal conditions. Furthermore, resolution of carrageenan-induced paw edema is comparable in all genotypes. However, LYVE-1(-/-)/CD44-/- mice exhibit increased edema formation in a carrageenan-induced paw inflammation model compared to wild-type mice, but not to LYVE(-/-) or CD44(-/-) mice. These data suggest that LYVE-1 and CD44 are not required for the formation or function of lymphatics, but do not rule out a role for LYVE-1 in inflammation.

AB Endothelial progenitor cells (EPCs) may provide novel opportunities for therapeutic angiogenesis after ischemic diseases. However, it is unclear how the angiogenic potential of EPCs might be affected by an inflammatory environment. We examine how the potent cytokine interleukin-1 beta (IL-1 beta) affects angiovasculogenic responses in EPCs in culture. Mononuclear cells isolated from mouse spleen were plated on fibronectin-coated wells and grown in EGM-2MV media. Endothelial progenitor cells were phenotyped using multiple markers (UEA-Lectin, ac-LDL, CD133, CD34, vWillebrand Factor, Flk-1) and to identify the IL-1 Receptor-I. We quantified cell and colony counts and performed MTT (3-(4,5-dimethylthiazol-2-yl) 2,5-diphenyl-tetrazolium bromide) and Matrigel assays, in vitro, under control and IL-1 beta (10 ng/mL) conditions. Endothelial progenitor cells exposed to IL-1 beta increased in the number of cells and colonies compared with untreated cells, without any effect on cell metabolic integrity. Furthermore, IL-1 beta treatment augmented EPC angiogenic function, significantly increasing the number of vessel-like structures in the Matrigel assay. An early phosphorylation of ERK1/2 occurred after IL-1 beta stimulation, and this pathway was inhibited if IL-1 Receptor-I was blocked. Our results suggest that IL-1 beta is a potent stimulator of in vitro angiogenesis through ERK signaling in mouse EPCs. Further studies are warranted to assess how interactions between proinflammatory environments and EPC responses may be leveraged to enhance therapeutic angiogenesis.

AB Warfarin-associated intracerebral hemorrhage (W-ICH) is a severe type of stroke. There is no consensus on the optimal treatment for W-ICH. Using a mouse model, we tested whether the rapid reversal of anticoagulation using human prothrombin complex concentrate (PCC) can reduce hemorrhagic blood volume. Male CD-1 mice were treated with warfarin (2 mg/kg over 24 h), resulting in a mean (+/- s.d.) International Normalized Ratio of 3.5 +/- 0.9. First, we showed that an intravenous administration of human PCC rapidly reversed anticoagulation in mice. Second, a stereotactic injection of collagenase was administered to induce hemorrhage in the right striatum. Forty-five minutes later, the animals were randomly treated with PCC (100 U/kg) or saline IV (n = 12 per group). Twenty-four hours after hemorrhage induction, hemorrhagic blood volume was quantified using a photometric hemoglobin assay. The mean hemorrhagic blood volume was reduced in PCC-treated animals (6.5 +/- 3.1 mu L) compared with saline controls (15.3 +/- 11.2 mu L, P = 0.015). In the saline group, 45% of the mice developed large hematomas (i.e., > 15 mu L). In contrast, such extensive lesions were never found in the PCC group. We provide experimental data suggesting PCC to be an effective acute treatment for W-ICH in terms of reducing hemorrhagic blood volume. Future studies are needed to assess the therapeutic potential emerging from our finding for human W-ICH.

COMMUNICATION; GABA; EEG; PHARMACOKINETICS; DRUGS
AB Neonatal seizures have devastating consequences for brain development and are inadequately treated by available antiepileptics. In neonates, gamma-aminobutyric acid (GABA) is an excitatory neurotransmitter due to elevated levels of intraneuronal chloride achieved by robust activity of the Na(+)-K(+)-2Cl(-) cotransporter (NKCC1). This depolarizing action of GABA likely contributes to the lowered seizure threshold, increased seizure propensity, and poor efficacy of GABAergic anticonvulsants among infants. The diuretic bumetanide inhibits NKCC1 and silences seizure activity in rodent models of neonatal seizures, but its effect on seizures in human neonates is unknown. Continuous electroencephalography (EEG) monitoring was used to quantify the number, duration, and frequency of seizures 2 hours before and after the administration of bumetanide in a neonate with intractable multifocal seizures. Significant reductions in mean seizure duration and frequency were noted following treatment, with no associated clinical side effects or metabolic imbalances. These results suggest bumetanide may exert antiepileptic effects in human neonates.

AB Study Objective: To evaluate the effect of dexmedetomidine combined with fentanyl on hemodynamics.
Design: Prospective, double-blinded, randomized study.
Setting: Operating room of a university hospital.
Patients: 30 ASA physical status II and III patients with mild-to-moderate cardiovascular disease.
Interventions: Patients were assigned to one of three groups: Group D-F2 [dexmedetomidine, effect-site concentration (ESC) of fentanyl = two ng/mL]; Group F2 (placebo, ESC of fentanyl = two ng/mL), or Group F4 (placebo, ESC of fentanyl = 4 ng/mL).
Measurements: Dexmedetomidine (an initial dose of 1.0 mu g/kg for 10 min, followed by a continuous infusion of 0.7 mu g-kg(-1.)hr(-1)) or placebo saline was administered 15 minutes before anesthetic induction. Anesthesia was induced with propofal and fentanyl using a target-controlled infusion system. Hemodynamic parameters: systolic (SBP) and diastolic blood pressures (DBP), and heart rate (HR) during anesthetic induction were measured and the percent changes were calculated for both induction and intubation.
Main Results: After inducing anesthesia, SBP was significantly higher in Group D-F2 (127 24 mmHg) than Group F2 (90 +/- 20 mmHg) or Group F4 (77 +/- 21 mmHg). The SBP in Groups F2 and F4 reached 160 +/- 31 mmHg and 123 +/- 36 mmHg, respectively, after intubation, but no significant change in SBP was noted in Group D-F2. The percent increase in SBP due to tracheal intubation in Group D-F2 was 3% +/- 4% and was significantly lower than that of Group F2 (70% +/- 34%) or Group F4 (45% +/- 36%).
Conclusion: Dexmedetomidine combined with fentanyl during anesthetic induction suppresses the decrease in blood pressure due to anesthetic induction and also blunts the cardiovascular response to tracheal intubation. (C) 2009 Elsevier Inc. All rights reserved.

AB The identification of biomarkers that distinguish between aggressive and indolent forms of prostate cancer (PCa) is crucial for diagnosis and treatment. In this study, we used cultured cells derived from prostate tissue from patients with PCa to define a molecular mechanism underlying the most aggressive form of PCa that involves the functional activation of eNOS and HIFs in association with estrogen receptor beta (ER beta). Cells from patients with poor prognosis exhibited a constitutively hypoxic phenotype and increased NO production. Upon estrogen treatment, formation of ER beta/eNOS, ER beta/HIF-1 alpha, or ER beta/HIF-2 alpha combinatorial complexes led to chromatin remodeling and transcriptional induction of prognostic genes. Tissue microarray analysis, using an independent cohort of patients, established a hierarchical predictive power for these proteins, with expression of eNOS plus ER beta and nuclear eNOS plus HIF-2 alpha being the most relevant indicators of adverse clinical outcome. Genetic or pharmacologic modulation of eNOS expression and activity resulted in reciprocal conversion of the transcriptional signature in cells from patients with bad or good outcome, respectively, highlighting the relevance of eNOS in PCa progression. Our work has considerable clinical relevance, since it may enable the earlier diagnosis of aggressive PCa through routine biopsy assessment of eNOS, ER beta, and HIF-2 alpha expression. Furthermore, proposing eNOS as a therapeutic target fosters innovative therapies for PCa with NO inhibitors, which are employed in preclinical trials in non-oncological diseases.

AB Purpose
When successive randomized trials contradict prior evidence, clinicians may be unsure how to evaluate them: Does accumulating evidence warrant changing practice? An increasingly popular solution, Bayesian statistics quantitatively evaluate new results in context. This study provides a clinically relevant example of Bayesian methods.
Methods
Three recent non-small-cell lung cancer adjuvant chemotherapy trials were evaluated in light of prior conflicting data. Results were used from International Adjuvant Lung Trial (IALT), JBR. 10, and Adjuvant Navelbine International Trialist Association (ANITA). Prior evidence was sequentially updated to calculate the probability of each survival benefit level (overall and by stage) and variance. Sensitivity analysis was performed using expert opinion and uninformed estimates of survival benefit prior probability.
Results
The probability of a 4% survival benefit increased from 33% before IALT to 64% after IALT. After sequential updating with JBR. 10 and ANITA, this probability was 82% (hazard ratio = 0.84; 95% CI, 0.77 to 0.91). IALT produced the largest decrease in variance (61%) and decreased the chance of survival decrement to 0%. Sensitivity analysis did not support a survival benefit after IALT. However, sequential updating substantiated a 4% survival benefit and, for stage II and III, more than 90% probability of a 6% benefit and 50% probability of a 12% benefit.
Conclusion
When evaluated in context with prior data, IALT did not support a 4% survival benefit. However, sequential updating with JBR. 10 and ANITA did. A model for future assessments, this study demonstrates the unique ability of Bayesian analysis to evaluate results that contradict prior evidence.

AB Objectives: To provide a brief description of the pathophysiology of akathisia, the challenges of diagnosing and treating this condition, and potential associated clinical issues. Also, to provide a review of the literature on the incidence of drug-induced akathisia associated with the use of second-generation antipsychotics (SGAs) and first-generation antipsychotics (FGAs).
Data Sources: English-language literature with no date restrictions cited in PubMed was searched for the keywords akathisia, placebo, neuroleptic or haloperidol, and the generic names of SGAs (clozapine, risperidone, olanzapine, quetiapine, ziprasidone, or aripiprazole).
Study Selection: Limits were set to search clinical trials, meta-analyses, or randomized controlled trials reviewing data from adult schizophrenia or bipolar disorder clinical trials. Studies including SGA comparisons with placebo and with FGAs, and also between SGAs themselves, were selected. Studies that specifically assessed akathisia (either subjectively or objectively or both) were included. Studies reporting generalized results pertaining to extrapyramidal symptoms (EPS) were excluded.
Data Extraction: The incidence of akathisia. EPS rating scores, and required medications for the management of movement disorders were reviewed.
Data Synthesis: Seventy-seven trials were included in the comparative review. Akathisia was observed with the use of all the SGAs. The akathisia incidence reported in bipolar disorder trials was generally higher compared with schizophrenia trials. The incidence reported for FGAs was consistently higher than that reported for SGAs, regardless of the patient population studied.
Conclusions: Akathisia remains a concern with the use of SGAs. More accurate and standardized evaluations are required for a better understanding of the nature and incidence of akathisia. J Clin Psychiatry 2009:70(5):627-643 (C) Copyright 2009 Physicians Postgraduate Press, Inc.

MANIA; CBCL; ADOLESCENTS; COMORBIDITY
AB Objective: To examine the predictive utility of the Child Behavior Checklist-Pediatric Bipolar Disorder (CBCL-PBD) profile to help identify children at risk for bipolar disorder.
Method: Subjects were ascertained from 2 identically designed longitudinal case-control family studies of subjects (males and females aged 6-18 years) with DSM-III-R attention-deficit/hyperactivity disorder (ADHD). Based on data from the baseline assessment, ADHD subjects without a lifetime diagnosis of bipolar disorder were stratified by the presence (CBCL-PBD positive. N = 28) or absence (CBCL-PBD negative, N = 176) of a CBCL-PBD score >= 210 (total of attention, aggression, and anxious/depressed subscales). Subjects were comprehensively assessed at follow-up with structured psychiatric interviews. Data were collected from April 1988 to February 2003.
Results: Over a mean follow-up period of 7.4 years, a positive CBCL-PBD score predicted subsequent diagnoses of bipolar disorder, major depressive disorder, and conduct disorder, as well as impaired psychosocial functioning and higher risk for psychiatric hospitalization.
Conclusions: This work suggests that a positive CBCL-PBD score based on elevations on the attention problems, aggressive behavior, and anxious/depressed subscales predicts subsequent pediatric bipolar disorder and associated syndrome-congruent impairments. if confirmed in other studies, the CBCL-PBD score has the potential to help identify children at high risk to develop bipolar disorder.

AB Objective: To compare the prevalence estimates, comorbidity rates, and structural validity of a revised symptom criteria set for the diagnosis of posttraumatic stress disorder (PTSD) with those of the DSM-IV criteria in a representative community sample of adolescents.
Method: Cross-sectional data from the National Survey of Adolescents, a 1995 household probability sample of 4,023 adolescents aged 12-17 year:, were examined. DSM-IV PTSD symptoms were assessed with a modification of the National Women's Study PTSD module. Three- and 4-factor DSM-IV models were compared to a 2-factor PTSD model that deleted symptoms potentially overlapping with depression or other anxiety disorders. Comorbidity was assessed using DSM-IV criteria for major depressive episodes and substance use disorders.
Results: PTSD prevalence varied across models (ie, 5.2%-8.8%, lifetime; 3.2%-5.7%, past 6 months). When the 2-factor model was used with a proportionate symptom threshold, lifetime PTSD prevalence wits comparable to that with the 3-factor DSM-IV model, and major depressive episode comorbidity was reduced by 9%-14%. Comorbidity with substance use disorders was comparable across models. Structural validity, tested with confirmatory factor analyses, showed that the 2-factor model and a 4-factor DSM-IV model were superior to the DSM-IV 3-factor model.
Conclusions: Compared to the DSM-IV 3-factor PTSD model, a 2-factor model that removed depression and anxiety symptoms and used a proportionate symptom threshold may produce comparable lifetime PTSD prevalence estimates, reduced PTSD-depression comorbidity, and Superior structural validity (comparable to a 4-factor PTSD model) when applied to community samples of adolescents. Further research on PTSD structure and diagnosis with adolescents is warranted. J Clin Psychiatry 2009:70(5):748-755 (C) Copyright 2009 Physicians Postgraduate Press, Inc.

AB We evaluated whether prior semantic knowledge would enhance episodic learning in amnesia. Subjects studied prices that are either congruent or incongruent with prior price knowledge for grocery and household items and then performed a forced-choice recognition test for the studied prices. Consistent with a previous report, healthy controls' performance was enhanced by price knowledge congruency; however, only a subset of amnesic patients experienced the same benefit. Whereas patients with relatively intact semantic systems, as measured by an anatomical measure (i.e., lesion involvement of anterior and lateral temporal lobes), experienced a significant congruency benefit, patients with compromised semantic systems did not experience a congruency benefit. Our findings suggest that when prior knowledge structures are intact, they can support acquisition of new episodic information by providing frameworks into which such information can be incorporated.

AB Three individuals with total laryngectomy were studied for their ability to control a hands-free electrolarynx (EL) using neck surface electromyography (EMG) for on/off and pitch modulation. The laryngectomy surgery of participants was modified to preserve neckstrap musculature for EMG-based EL control (EMG-EL), with muscles on one side maintaining natural innervation and those on the other side receiving a transferred recurrent laryngeal nerve (RLN). EMG from each side of the neck controlled the EMG-EL across a day of unstructured practice followed by a day of formal training, including EMG biofeedback. Using either control source, participants spoke intelligibly and fluently with the EMG-EL before formal training. This good initial performance did not consistently improve across testing for either control source in terms of voice timing, speech intelligibility, fluency, and intonation of interrogative versus declarative sentences. Neck strap muscles have activation patterns capable of simple alaryngeal voice control without requiting RLN transfer.
Learning outcomes: The reader will better understand (1) functionality of the hands-free electrolarynx (2) modification of laryngectomy surgery to preserve neck strap musculature and (3) performance of hands-free electrolarynx with different control sources.

AB Purpose: The purpose of this study was to compare 2-dimensional (2D) and 3D magnetic resonance cholangiopancreatography (MRCP) for image quality and diagnostic performance in the evaluation of pathologically verified intraductal papillary mucinous neoplasm (IPMN) of the pancreas.
Materials and Methods: In this institutional review board-approved retrospective review, 21 patients (14 women and 7 men; mean age, 69 years; range, 43-93 years) who underwent 2D and 3D MRCPs oil a 1.5-T system for pathologically confirmed IPMN were studied. Two-dimensional MRCP protocol included multiplanar thin- and thick-slab single-shot fast spin-echo imaging, coronal single-shot fast spin-echo, and transverse T2-weighted fast spin-echo imaging. Three-dimensional MRCP was performed using a fast-recovery fast spin-echo sequence with single-volume acquisition and maximum intensity projection reconstructions. Using a 5-point scale, 2 readers independently evaluated MRCPs for (1) image quality, (2) visualization of the pancreatic duct (PD), and (3) Visualization of the cystic lesions. Intraductal papillary mucinous neoplasm's morphological features (septa, mural nodules, and duct communication) were also graded similarly to predict benignity or malignancy. Surgical and pathological data served as reference standard. A pancreatic surgeon reviewed the 21 MRCPs to determine the usefulness of 3D MRCP compared with that of 2D MRCP for Surgical planning.
Results: Of the 21 IPMNs, 11 were side-branch IPMNs and 10 were main-duct-lesions IPMNs with side-branch involvement. A statistically significant improvement in image quality and Visualization of the PD and cystic lesion was demonstrated with 3D MRCP in comparison with that demonstrated with 2D MRCP (P <= 0.002). The morphological details of IPMN were also identified, with higher confidence with 3D MRCP in comparison with that using 2D MRCP Two-dimensional and 3D MRCPs performed similarly for predicting benign and malignant lesions, with sensitivity ranging from 50.0% to 66.7% and specificity ranging from 86.7% to 93.3%. The pancreatic surgeon preferred 3D to 2D MRCP for surgical evaluation and planning in 14 of 21 cases.
Conclusion: Compared with 2D MRCP, 3D MRCP provides better image quality, offers superior evaluation of the PD and morphological details of IPMN, and is preferred for surgical planning.

AB The aim of the study was to describe computed tomography (CT) findings in middle ear cholesteatoma in pediatric patients. A cohort of 32 children with cholesteatoma (3-14 years old) entered the study. Froth them, 30 presented acquired cholesteatoma (AC), and 2 presented congenital cholesteatoma. All of the children were investigated using CT before surgery of the middle ear and mastoid. Computed tomography was performed with 1- or 2-mm axial and coronal sections of both temporal bones. Nineteen children with AC (63.3%) revealed a diffuse soft-tissue density isodense with muscle, whereas in 6 of them, the mass mimicked inflammation. The remaining revealed localized soft-tissue mass with partially lobulated contour. In AC, ossicular erosion was detected in 23 cases (76.7%), abnormal pneumatization in 19 cases (63.3%), and erosion-blunting of spur and enlargement of middle ear or mastoid in 8 cases (26.7%). The 2 congenital cholesteatomas revealed soft-tissue mass with polypoid densities, while a semicircular canal fistula was detected in one of them. High-resolution CT facilitates early diagnosis and appropriate treatment of pediatric cholesteatoma by assessing the anatomic abnormalities and the extent of disease, which are crucial in middle ear and mastoid surgery.

AB Helicobacter pylori is etiologically related to peptic ulcer disease and gastric adenocarcinomas. Reports of geographical enigmas (African, Asian, Indian and Costa Rican enigmas) are based on perceptions that clinical presentations in a population or region are not as the authors expected. We discuss the background for these enigmas and examine the evidence whether they are real or are medical myths. The African enigma was challenged almost as soon as it was proposed and recent analyses of endoscopic data have confirmed it is a myth, as H. pylori-related diseases occur in Africa at the expected frequencies. The Asian and Indian enigmas relate to gastric cancer and peptic ulcers, respectively, and when one takes the patterns of gastritis in the different regions, these enigmas disappear. The pattern of gastritis underlies and predicts the clinical outcome and the predominant pattern of gastritis has been observed to change much more rapidly than can be accounted for by changes in host genetics. There is also no evidence that these changes relate to changes in the predominant H. pylori strain. The factors that link most closely to preventing an atrophic corpus are environmental, with food preservation and diet currently assuming the most prominent roles. This focus on diseases (cancer vs duodenal ulcers) instead of the underlying patterns of gastritis has fostered, and possibly helped to perpetuate, these mythical enigmas. We suggest that a better strategy would be to focus on the pathogenesis of underlying histopathologic differences which could also lead to the identification of specific chemoprevention strategies.

AB A retrospective analysis of 24 cases of minimally invasive, open reduction, and internal fixation of intra-articular calcaneal fractures is presented. Collected data included articular step-off, medial wall displacement, and Boehler's angle, in addition to other descriptive characteristics of the fracture and case series. The operative technique is described in detail including the optimal screw constructs. Arthroscopic assistance was used in 10 of the cases. The articular step-off of the posterior facet, medial wall displacement, and Boehler's angle all displayed statistically significant change between the preoperative and postoperative periods (P < .0001). These results were consistent with the goal of restoration of articular congruity, calcaneal morphology, and calcaneal height. There were no soft tissue complications. The mean overall follow-up duration was 2.8 years (range 1 to 10 years). Of the 18 patients who were followed for more than I year (range 1.0 to 10 years), none went on to subtalar fusion. The results of this study suggest that a minimally invasive approach can improve radiographic parameters consistent with the ultimate goals of operative reduction of calcaneal fractures, and can be used to achieve satisfactory results with minimal risk of wound complication.

AB Intestinal stem cell organoid transplantation generates functional intestinal neomucosa and has been used therapeutically to improve nutrient absorption and cure bile acid malabsorption in rats. We hypothesized that intestinal organoids can be harvested and transplanted to generate intestinal neomucosa in a large animal model.
In group 1, 2-month old beagles (n = 6) underwent autotransplantation of intestinal organoids prepared from a segment of their own ileum. In group 2, intestinal organoids were harvested from fetuses and allotransplanted into 10-month old mother animals (n = 4). Tissues were harvested after 4 weeks and analyzed by hematoxylin and eosin histology and fluorescent microscopy.
Large numbers of viable organoids were harvested in both groups. In group 1, no neomucosal growth was identified in any of the engraftment sites after autotransplantation of juvenile organoids. In group 2, neomucosal growth with large areas of crypts and villi was identified in 11 of 12 polyglycolic acid scaffolds after allotransplantation of fetal organoids. The neomucosa resembled normal canine mucosa in structure and composition.
Intestinal stem cell organoid transplantation can be used to generate neomucosa in dogs. This is the first report of successful generation of intestinal neomucosa using intestinal stem cell organoid transplantation in a large animal model.

AB Genetic variants of the warfarin sensitivity gene CYP2C9 have been associated with increased bleeding risk during warfarin initiation. Studies also suggest that such patients remain at risk throughout treatment.
Would testing patients with non-valvular atrial fibrillation (AF) for CYP2C9 before initiating warfarin improve outcomes?
Markov state transition decision model.
Ambulatory or inpatient settings necessitating new initiation of anticoagulation.
The base case was a 69-year-old man with newly diagnosed non-valvular AF. Interventions included: (1) warfarin, (2) aspirin, or (3) no antithrombotic therapy without genetic testing; and genetic testing followed by (4) aspirin or (5) no antithrombotic therapy in those with culprit CYP2C9 alleles.
Quality-adjusted life years (QALYs).
In the base case, testing and treating patients with CYP2C9*2 and/or CYP2C9*3 with aspirin rather than warfarin was best (8.97 QALYs). However, warfarin without genetic testing was a close second (8.96 QALYs), a difference of roughly 5 days. Sensitivity analyses demonstrated that genetic testing followed by aspirin was best for patients at lower risk of embolic events. Warfarin without testing was preferred if the rate of embolic events was greater than 5% per year, or the risk of major bleeding while receiving warfarin was lower.
For patients at average risk for ischemic stroke due to AF and at average risk for major hemorrhage, treatment based on genetic testing offers no benefit compared to warfarin initiation without testing. The gain from testing may be larger in patients at lower risk of embolic events or at greater risk of bleeding.

AB Depression and anxiety frequently co-occur with pain and may affect treatment outcomes. Early identification of these co-occurring psychiatric conditions during routine pain screening may be critical for optimal treatment.
To determine aspects of pain related to psychological distress, and, among distressed patients, to determine whether pain factors are related to provider identification of distress.
Cross-sectional interview of primary care patients and their providers participating in a Veteran's Administration HELP-Vets study.
A total of 528 predominately male Veterans
We measured self-reported pain, including a 0-10 numeric rating scale and interference items from the Brief Pain Inventory. To evaluate distress, brief indicators of depression, anxiety and PTSD were combined. A substantial number of patients had psychological distress (41%), which was even higher (62%) among patients with moderate-severe current pain. Only 29% of those with distress reported talking to their provider about emotional problems during their visit. In multivariate analyses, other pain factors related to distress included interference with enjoyment of life and relationships with others, pain in multiple locations and joint pains. Prior diagnoses of depression and anxiety were also related to current distress. Only prior diagnosis and patient reported headaches and sleep interference because of pain were related to provider identification of distress.
VA patients with moderate-severe pain are at high risk for psychological distress, which often goes unrecognized. Providers need to be more vigilant to mental health problems in patients experiencing high pain levels. Targeted screening for co-occurring conditions is warranted.

AB Purpose Surgical contracture release can restore motion to stiff elbows. Some authors suggest that use of continuous passive motion (CPM) in postoperative management can increase ultimate mobility. This study tests the null hypothesis that there is no difference in the arc of flexion and extension between patients who used CPM and those who did not use CPM after open elbow contracture release.
Methods Sixteen patients who had an arc of flexion and extension of less than 80 degrees and used CPM after open contracture release were matched based on age, gender, diagnosis, preoperative arc of flexion and extension, and radiographic appearance (joint congruity, heterotopic bone, and arthritis) to 16 control patients who did not use CPM. Stiffness was of posttraumatic origin in 24 patients, related to primary osteoarthrosis in 4 patients, and related to heterotopic ossification after central nervous system injury or burns in 4 patients. The preoperative arc of flexion and extension averaged 38 degrees in the CPM cohort and 42 degrees in the no-CPM cohort.
Results Subsequent surgeries included procedures to address residual stiffness in 1 patient in the CPM cohort and in 3 patients in the no-CPM cohort. At an average 6 months of follow-up, there was no difference in improvement in the arc of flexion and extension (58 degrees vs 61 degrees) between the CPM and no-CPM cohorts. At the final evaluation, the improvement in arc of flexion and extension (59 degrees in both cohorts) and the final arc of flexion and extension (96 degrees vs 101 degrees) were comparable between cohorts.
Conclusions These matched retrospective data do not demonstrate a benefit of CPM in the postoperative management of elbow contracture release. (J Hand Surg 2009;34A:858-865. (C) 2009 Published by Elsevier Inc. on behalf of the American Society for Surgery of the Hand.)

AB Low-income immigrant Latinos are particularly vulnerable to disasters because they are both ill-prepared and disproportionately affected. Disaster preparedness programs that are culturally appropriate must be developed and tested. To develop such a program, we conducted 12 focus groups with low-income immigrant Latinos to understand their perceptions and understanding of disaster preparedness, and facilitators and obstacles to it. Participants were concerned about remaining calm during an earthquake. Obstacles to storage of disaster supplies in a kit and developing a family communication plan were mentioned frequently. Misunderstandings were voiced about the proper quantity of water to store and about communication plans. Several focus groups spontaneously suggested small group discussions (platicas) as a way to learn about disaster preparedness. They wanted specific help with building their family communication plans. They rated promotoras de salud highly as potential teachers. Results Will guide the development of a disaster preparedness program tailored to the needs of low-income Latino immigrants.

AB TCR beta chain repertoire of peripheral alpha beta T cells is generated through the stepwise assembly and subsequent selection of TCR beta V region exons during thymocyte development. To evaluate the influence of a two-step recombination process on V beta rearrangement and selection, we generated mice with a preassembled D beta 1J beta 1.1 complex on the J beta 1(omega) allele, an endogenous TCRP allele that lacks the D beta 2-J beta 2 cluster, creating the J beta 1(DJ beta) allele. As compared with J beta 1(omega/omega) mice, both J beta 1(DJ beta/omega) and J beta 1(DJ beta/DJ beta) mice exhibited grossly normal thymocyte development and TCR beta allelic exclusion. In addition, V beta rearrangements on J beta 1(DJ beta) and J beta 1(omega) alleles were similarly regulated by TCR beta-mediated feedback regulation. However, in-frame V beta DJ beta rearrangements were present at a higher level on the J beta 1(DJ beta) alleles of J beta 1(DJ beta/omega) alpha beta T cell hybridomas, as compared with on the J beta 1(omega) alleles. This bias was most likely due to both an increased frequency of VP-to-DJ beta rearrangements on J beta 1(DJ beta) alleles and a preferential selection of cells with in-frame V beta DJ beta exons assembled on J beta 1(DJ beta) alleles during the development of J beta 1(DJ beta/omega) alpha beta T cells. Consistent with the differential selection of in-frame V beta DJ beta rearrangements on J beta 1(DJ beta) alleles, the V beta repertoire of alpha beta T cells was significantly altered during alpha beta TCR selection in J beta 1(DJ beta/omega) and J beta 1(DJ beta/DJ beta) mice, as compared with in J beta 1(omega/omega) mice. Our data indicate that the diversity of DJ beta complexes assembled during thymocyte development influences TCR beta chain selection and peripheral VP repertoire.

AB Consumption of green tea polyphenols (GTPs) in drinking water prevents photocarcinogenesis in mice; however, the molecular mechanisms underlying this effect have not been fully elucidated. Using IL-12p40 knockout (KO) mice and their wild-type counterparts and an established photocarcinogenesis protocol, we found that although administration of GTPs (0.2%, w/v) in drinking water significantly reduced UVB-induced tumor development in wild-type mice, this treatment had a nonsignificant effect in IL-12-KO mice. GTPs resulted in reduction in the levels of markers of inflammation (cyclooxygenase-2, prostaglandin E(2), proliferating cell nuclear antigen, and cyclin D1) and proinflammatory cytokines (tumor necrosis factor-alpha, IL-6, and IL-1 beta) in chronically UVB-exposed skin and skin tumors of wild-type mice but less effective in IL-12p40-KO mice. UVB-induced DNA damage (cyclobutane pyrimidine dimers) was resolved rapidly in GTPs-treated wild-type mice than untreated wild-type mice and this resolution followed the same time course as the GTPs-induced reduction in the levels of inflammatory responses. This effect of GTPs was less pronounced in IL-12-KO mice. The above results were confirmed by treatment of IL-12-KO mice with murine recombinant IL-12 and treatment of wild-type mice with neutralizing anti-IL-12 antibody. To our knowledge, it is previously unreported that prevention of photocarcinogenesis by GTPs is mediated through IL-12-dependent DNA repair and a subsequent reduction in skin inflammation.

AB The immune response of a host to an invading pathogen is dependent on the capacity of its immune cell compartment to recognize highly conserved pathogen components using an ancient class of pattern recognition receptors known as Toll-like receptors (TLRs). Initiation of TLR-mediated signaling results in the induction of proinflammatory cytokines that help govern the scale and duration of any ensuing response. Specificity for TLR signaling is, in part, a result of the differential recruitment of intracellular adaptor molecules. Of these, MyD88 is required for the majority of TLR signaling. Zebrafish have been shown to possess TLRs and adaptor molecules throughout early development, including MyD88, strongly suggesting conservation of this ancient defense mechanism. However, information about which embryonic cells/tissues possess this conserved signaling potential is lacking. To help define which embryonic cells, in particular, those of the innate immune system, have the potential for MyD88-dependent, TLR-mediated signaling, we generated transgenic reporter lines using regulatory elements of the myd88 gene to drive the fluorescent reporters enhanced GFP and Discosoma red fluorescent protein 2 within live zebrafish. These lines possess fluorescently marked cells/tissues consistent with endogenous myd88 expression, including a subset of myeloid leukocytes. These innate immune cells were confirmed to express other TLR adaptors including Mal, trif, and Sarm. Live wound-healing and infection assays validated the potential of these myd88-expressing leukocytes to participate in immune responses. These lines will provide a valuable resource for further resolving the contribution of MyD88 to early vertebrate immunity. J. Leukoc. Biol. 85: 751-765; 2009.

AB Severe injury disrupts normal immune regulation causing a transient hyperinflammatory reaction and suppressed adaptive immune function. This report addresses the potential contribution of dendritic cells (DC) to changes in adaptive immune function after injury by specifically measuring injury-induced changes in splenic DC numbers and subsets, cell-surface markers, TLR responses, and APC function. Using a mouse burn injury model, we found that injury did not markedly alter the relative percentage of lymphoid, myeloid, or plasmacytoid DC in the spleens of burn-injured mice. Moreover, we did not observe a significant reduction in cell-surface expression of several major costimulatory molecules, CD40, CD80, CD86, programmed death 1 ligand, ICOS ligand, and B7-H3, on DC. Instead, we observed increased cell-surface expression of CD86 at 1 day after injury with no significant changes in costimulatory molecule expression at 7 days after injury, suggesting that burn injury causes an early activation of DC. In addition, injury did not suppress DC reactivity to TLR2, TLR4, or TLR9 agonists. Most important, DC prepared from injured mice were able to present peptide antigen to naive OTII TCR transgenic CD4+ T cells as efficiently and effectively as DC from sham-injured mice. We also found that CD4 T cells stimulated with antigen presented by DC from sham or burn mice showed similar levels of IL-2, IFN-gamma, IL-10, and IL-13 production. Taken together, these findings support the conclusion that DC do not acquire a suppressive phenotype following severe injury in mice. J. Leukoc. Biol. 85: 862-870; 2009.

AB Several observations suggest endogenous suppressors of inflammatory mediators are present in human blood. alpha-1-Antitrypsin (AAT) is the most abundant serine protease inhibitor in blood, and AAT possesses anti-inflammatory activity in vitro and in vivo. Here, we show that in vitro stimulation of whole blood from persons with a genetic AAT deficiency resulted in enhanced cytokine production compared with blood from healthy subjects. Using whole blood from healthy subjects, dilution of blood with RPMI tissue-culture medium, followed by incubation for 18 h, increased spontaneous production of IL-8, TNF-alpha, IL-1 beta, and IL-1R antagonist (IL-1Ra) significantly, compared with undiluted blood. Dilution-induced cytokine production suggested the presence of one or more circulating inhibitors of cytokine synthesis present in blood. Serially diluting blood with tissue-culture medium in the presence of cytokine stimulation with heat-killed Staphylococcus epidermidis (S. epi) resulted in 1.2- to 55-fold increases in cytokine production compared with S. epi stimulation alone. Diluting blood with autologous plasma did not increase the production of IL-8, TNF-alpha, IL-1 beta, or IL-1Ra, suggesting that the endogenous, inhibitory activity of blood resided in plasma. In whole blood, diluted and stimulated with S. epi, exogenous AAT inhibited IL-8, IL-6, TNF-alpha, and IL-1 beta significantly but did not suppress induction of the anti-inflammatory cytokines IL-1Ra and IL-10. These ex vivo and in vitro observations suggest that endogenous AAT in blood contributes to the suppression of proinflammatory cytokine synthesis. J. Leukoc. Biol. 85: 886-895; 2009.

AB We visualized inhomogeneous local magnetic field (internal magnetic field) gradients arising from susceptibility contrast between an array of cylindrical glass tubes (solid matrix) and surrounding water (pore fluids) in a uniform applied magnetic field. MRI was performed to determine the spatially resolved decay rates due to diffusion in the internal magnetic field which were proportional to the strength of local gradient. We also spatially resolved the interference pattern of the cross-terms between the internal and the applied field gradient in order to extract the orientation of the internal field gradient. These experimental results were found to be consistent with the theoretical calculations. This work demonstrates a simple yet representative case for visualizing the strength and orientation of the local susceptibility induced magnetic field gradients in porous media.

AB A novel combination of culturing and DNA-based terminal restriction fragment length polymorphism (TRFLP) analysis was used to investigate the effect of probiotics on antibiotic-induced gut microbiota alterations to determine if a probiotic preparation containing bifidobacteria and lactobacilli, taken during and after antibiotic therapy, can minimize antibiotic disturbance of faecal microbiota. Healthy subjects administered amoxicillin/clavulanate were randomized and concomitantly received a placebo or probiotic mixture. The primary end point was similarity of faecal microbiota as determined by culturing and TRFLP from subjects taking, probiotics compared to those taking a placebo measured by comparing data from baseline to post-treatment for each subject. TRFLP analysis revealed a high subject to subject variation in the baseline faecal microbiota. The most common antibiotic-induced disturbance was a relative increase in Clostridium, Eubacterium, Bacteroides and Enterobacteraceae. The mean similarity to the baseline increased over time in both treatment groups, although the probiotic group was less disturbed according to both TRFLP and culture data. The culture method revealed that post-antibiotic faecal microbiota in probiotic-consuming subjects were more similar to the baseline microbiota than the control group (P=0.046). Changes in Enterobactereaceae (P=0.006) and Bifidobacterium (P=0.030) counts were significantly different between the groups. Analysis of TRFLP data reinforced the trend between groups but was not statistically significant (P=0.066). This study indicates this mixture of probiotics promotes a more rapid return to pre-antibiotic baseline faecal bacterial microbiota.

AB Lynch syndrome is caused by germline mutations in DNA mismatch repair (MMR) genes. Both microsatellite instability (MSI) testing and immunohistochemical analyses (IHC) of colon cancers are valuable diagnostic strategies for Lynch syndrome. We sought to determine whether these markers of MMR deficiency were also detectable in pre-cancerous colorectal adenomas. Fifteen subjects with a germline MMR gene mutation who had 44 adenomas removed during surveillance colonoscopy were identified. MSI testing and IHC for MLH1, MSH2, and MSH6 were performed. MSI was detected in 23 adenomas. There was a significant association between MSI and high-grade dysplasia (P = 0.006) and distal location (P = 0.0008). Loss of MMR protein by IHC was detected in 31 adenomas. A significant association was observed between loss of staining by IHC and high-grade dysplasia (P = 0.04). Among the 40 adenomas in which both MSI tests and IHC were performed, the presence of a germline mutation correlated with an abnormal MSI result in 58% of cases, an abnormal IHC result in 70% of cases, and either an abnormal MSI or IHC result in 73% of cases. The combination of MSI and IHC testing in colorectal adenomas is a sensitive screen for the detection of Lynch syndrome and may be particularly useful when Lynch syndrome is suspected and adenomatous polyps are the only tissues available for analysis.

AB Previous studies have implicated the unfolded protein response (UPR) in the pathogenesis of Alzheimer's disease (AD). We previously reported that DNA variants in the ubiquilin 1 (UBQLN1) gene increase the risk for AD. Since UBQLN1 has been shown to play a role in the UPR, we assessed the effects of overexpression and downregulation of UBQLN1 splice variants during tunicamycin-induced ER stress. In addition to previously described transcript variants, TV1 and TV2, we identified two novel transcript variants of UBQLN1 in brain: TV3 (lacking exons 2-4) and TV4 (lacking exon 4). Overexpression of TV1-3, but not TV4 significantly decreased the mRNA induction of UPR-inducible genes, C/EBP homologous protein (CHOP), BiP/GRP78, and protein disulfide isomerase (PDI) during the UPR. Stable overexpression of TV1-3, but not TV4, also significantly decreased the induction of CHOP protein and increased cell viability during the UPR. In contrast, downregulation of UBQLN1 did not affect CHOP mRNA induction, but instead increased PDI mRNA levels. These findings suggest that overexpression UBQLN1 transcript variants TV1-3, but not TV4, exert a protective effect during the UPR by attenuating CHOP induction and potentially increasing cell viability.

AB Disparities in American health care based on socially-defined patient characteristics such as race, ethnicity, and socioeconomic position are well-documented. We review differences and disparities in incidence, pathobiology, processes and outcomes of care, and survival based on social factors for brain tumors of all histologies. In the US, black patients have lower incidences of most brain tumor types and lower-income patients have lower incidences of low grade glioma, meningioma and acoustic neuroma; ascertainment bias may contribute to these findings. Pathogenetic differences between malignant gliomas in patients of different races have been demonstrated, but their clinical significance is unclear. Patients in disadvantaged groups are less often treated by high-volume providers. Mortality and morbidity of initial treatment are higher for brain tumor patients in disadvantaged groups, and they present with markers of more severe disease. Long term survival differences between malignant glioma patients of different races have not yet been shown. Clinical trial enrollment appears to be lower among brain tumor patients from disadvantaged groups. We propose future research both to better define disparities and to alleviate them.

AB Neurofibromatosis type 2 (NF2) is a tumor suppressor gene syndrome characterized by multiple schwannomas, especially vestibular schwannomas (VS), and meningiomas. Anticancer drug trials are now being explored, but there are no standardized endpoints in NF2. We review the challenges of NF2 clinical trials and suggest possible response criteria for use in initial phase II studies. We suggest two main response criteria in such trials. Objective radiographic response is defined as a durable 20% or greater reduction in VS volume based on post-contrast T1-weighted MRI images collected with 3 mm or finer cuts through the internal auditory canal. Hearing response is defined as a statistically significant improvement in word recognition scores using 50-word recorded lists in audiology. A possible composite endpoint incorporating both radiographic response and hearing response is outlined. We emphasize pitfalls in response assessment and suggest guidelines to minimize misinterpretations of response. We also identify research goals in NF2 to facilitate future trial conduct, such as identifying the expectations for time to tumor progression and time to measurable hearing loss in untreated NF2-related VS, and the relation of both endpoints to patient prognostic factors (such as age, baseline tumor volume, and measures of disease severity). These data would facilitate future use of endpoints based on stability of tumor size and hearing, which might be more appropriate for testing certain drugs. We encourage adoption of standardized endpoints early in the development of phase II trials for this population to facilitate comparison of results across trials of different agents.

AB Introduction Cerebral metastases are a common problem and pose complex treatment decisions, with reference to local control of treated lesions, prevention of new brain metastases, and toxicity of available treatments. At the 2007 Congress of Neurological Surgeons (CNS) Annual Meeting, a novel active learning process, called Integrated Medical Learning(SM), was used to better understand contemporary practice patterns and to monitor the success of education about these critical treatment decisions. Methods CNS members received an electronically distributed premeeting survey and educational materials about single and multiple cerebral metastasis treatment; practice patterns were elicited. At the Annual Meeting, 496 surgeons were polled using handheld devices before and after surgical and radiation oncology expert presentations. Surgeons who had answered premeeting surveys received a second, postmeeting questionnaire. Results In the premeeting questionnaire (N = 214), higher current volume of practice, Tumor Section membership, and academic practice predicted more correct answers (P < 0.05 for all). Fifty five percent favored routine whole brain radiotherapy (WBRT) after metastasis resection. Thirty four percent "most often" used radiosurgery to the resection bed; these respondents cited "cognitive changes" in justifying WBRT omission. At the meeting, expert presentations were followed by audience shifts toward adjuvant WBRT after resection (P = 0.01) or radiosurgery (P < 0.001)-topics for which class I evidence was discussed. There was no shift in preference for surgery or radiosurgery (P = 0.24) or multiple metastasis treatment (P = 0.8)-topics for which clear class I evidence was not presented. Postmeeting questionnaires showed retained knowledge among meeting attendees. Conclusions Using IML, we were able to study baseline knowledge and practice patterns for an important neuro-oncological treatment decision. Evidence suggested expert presentations were effective in changing audience opinion when relevant class I evidence was presented, and that knowledge was retained postmeeting.

TI Decreased rate of infection in glioblastoma patients with allelic loss

AB Introduction Chromosome 10q allelic loss commonly occurs in glioblastoma. Disruption of PTEN, one of three known 10q tumor suppressor genes, affects the immune system by increasing tumor expression of immunosuppressive protein B7-H1 and by increasing tumor release of Th2-inducing cytokines. While the former might impair antitumor cellular immunity, a consideration for immunotherapy, the latter could cause 10q-maintaining tumor patients to experience comparatively higher rates of bacterial infections, a source of morbidity and mortality in glioblastoma patients. Methods We retrospectively reviewed 58 glioblastoma patients whose tumors were designated "normal-10q" (n = 16) or "LOH-10q" (n = 42) using loss of heterozygosity (LOH) assays of microsatellite markers in constitutional/tumor DNA pairs. Records were reviewed for symptomatic, microbiologically or radiographically confirmed infections in the first 2 years after diagnosis. Results Infection occurred more frequently in "normal-10q" than "LOH-10q" patients (56% vs. 14% of patients experiencing infection; P = 0.001). "Normal-10q" patients more commonly developed all four infection types studied (urinary tract = 38% vs. 13%, craniotomy wound = 19% vs. 0%, pneumonia = 19% vs. 5%, sepsis = 6% vs. 3%). "Normal-10q" and "LOH-10q" patients had similar survival, ages, chemotherapy treatment rates, and frequency of patients on dexamethasone 1 month after radiation therapy (P = 0.4-0.98), making these factors unlikely to explain the observed difference in infection rates. Conclusion While tumor mutations may inhibit antitumor immunity, the effects of these mutations on systemic immunity remain undetermined. We found higher infection rates after glioblastoma diagnosis in patients whose tumors maintained chromosome 10q than in patients whose tumors had allelic 10q loss. Differing effects of this genetic alteration on antitumor and systemic immunity may warrant further investigation, potentially providing insight into mechanisms of antitumor immunity and host defenses against local and systemic infections.

AB Enhanced delivery and expression of genes in specific neuronal systems is critical for the development of genetic models of neurodegenerative disease and potential gene therapy. Recent discovery of new recombinant adeno-associated viral (rAAV) capsid serotypes has resulted in improved transduction efficiency, but expression levels, spread of transgene, and potential toxicity can differ depending on brain region and among species. We compared the transduction efficiency of titer-matched rAAV 2/1, 2/5, and 2/8 to the commonly used rAAV2/2 in the rat nigrostriatal system via expression of the reporter transgene, enhanced green fluorescent protein. Newer rAAV serotypes 2/1, 2/5, and 2/8 demonstrated marked increase in transduction and spread of enhanced green fluorescent protein expression in dopaminergic nigrostriatal neurons and projections to the striatum and globus pallidus compared to rAAV2/2 at 2 weeks post-injection. The number of nigral cells transduced was greatest for rAAV2/1, but for serotypes 2/5 and 2/8 was still two- to threefold higher than that for 2/2. Enhanced transduction did not cause an increase in glial cell response or toxicity. New rAAV serotypes thus promise improved gene delivery to nigrostriatal system with the potential for better models and therapeutics for Parkinson disease and other neurodegenerative disorders.

AB Following neuronal injury, microglia initiate repair by phagocytosing dead neurons without eliciting inflammation. Prior evidence indicates triggering receptor expressed by myeloid cells-2 (TREM2) promotes phagocytosis and retards inflammation. However, evidence that microglia and neurons directly interact through TREM2 to orchestrate microglial function is lacking. We here demonstrate that TREM2 interacts with endogenous ligands on neurons. Staining with TREM2-Fc identified TREM2 ligands (TREM2-L) on Neuro2A cells and on cultured cortical and dopamine neurons. Apoptosis greatly increased the expression of TREM2-L. Furthermore, apoptotic neurons stimulated TREM2 signaling, and an anti-TREM2 mAb blocked stimulation. To examine the interaction between TREM2 and TREM2-L in phagocytosis, we studied BV2 microglial cells and their engulfment of apoptotic Neuro2A. One of our anti-TREM2 mAb, but not others, reduced engulfment, suggesting the presence of a functional site on TREM2 interacting with neurons. Further, Chinese hamster ovary cells transfected with TREM2 conferred phagocytic activity of neuronal cells demonstrating that TREM2 is both required and sufficient for competent uptake of apoptotic neuronal cells. Finally, while TREM2-L are expressed on neurons, TREM2 is not; in the brain, it is found on microglia. TREM2 and TREM2-L form a receptor-ligand pair connecting microglia with apoptotic neurons, directing removal of damaged cells to allow repair.

AB Aim: Little is known about the concordance rate in twins for dementia with Lewy bodies (DLB). The rate of agreement between clinical and pathological diagnoses for DLB is typically low, necessitating confirmation of the diagnosis neuropathologically.
Methods: Participants were 17 twin pairs enrolled in the Duke Twins Study of Memory in Aging in which at least one member of the pair had an autopsy confirmed diagnosis of DLB, Alzheimer's disease (AD) with Lewy bodies or frontotemporal dementia with Lewy bodies. The characteristics of those with dementia were assessed and rates of concordance for pathological confirmed dementia were examined.
Results: Four monozygotic twin pairs had a proband with neuropathologically confirmed pure DLB; all remained discordant for dementia for periods up to 16 years or more. Five of 13 pairs in which the proband had AD plus DLB were concordant for dementia but only one pair was concordant for AD plus DLB, while the co-twins in the other four pairs had other types of dementia.
Conclusions: The present study indicates that even among twins, a diagnosis of DLB in one twin does not predict the same diagnosis in the other twin. Neuropathological discordance in type of dementia among monozygotic pairs hints at environmental or epigenetic factors playing a role in Lewy body pathology.

TI alpha-Synuclein S129 Phosphorylation Mutants Do Not Alter Nigrostriatal

AB Lewy bodies are found in Parkinson disease and related disorders and are extensively phosphorylated at Ser-129 (S129), but whether S129 phosphorylation mediates alpha-synuclein aggregation and neurotoxicity has been controversial. We used recombinant adeno-associated virus to overexpress alpha-synuclein in the rat nigrostriatal system. Rats were injected with recombinant adeno-associated virus 2/8 expressing either human wild-type (wt) or mutant alpha-synuclein with S129 replaced by alanine (S129A) or aspartate (S129D). Contralateral substantia nigra injections containing empty vector served as controls. Both wt and S129 mutants resulted in significant dopaminergic cell loss in the recipients by 6 weeks, but there were only small decreases in nigrostriatal terminal density and tyrosine hydroxylase expression. There were no significant differences in dopaminergic cell loss, nigrostriatal terminal density, or tyrosine hydroxylase expression among the wt and S129 mutants. Furthermore, we did not observe any differences in alpha-synuclein aggregate formation or distribution among wt and either S129 mutant. These findings contrast with those from previous studies and suggest that injections of both S129 phosphorylation mutants result in dopaminergic neurotoxicity similar to wt injections. Further study is needed to clarify the effects of these S129 Mutants and alpha-synuclein phosphorylation in mammalian systems.

AB Wig GS, Buckner RL, Schacter DL. Repetition priming influences distinct brain systems: evidence from task-evoked data and resting-state correlations. J Neurophysiol 101: 2632-2648, 2009. First published February 18, 2009; doi:10.1152/jn.91213.2008. Behavioral dissociations suggest that a single experience can separately influence multiple processing components. Here we used a repetition priming functional magnetic resonance imaging paradigm that directly contrasted the effects of stimulus and decision changes to identify the underlying brain systems. Direct repetition of stimulus features caused marked reductions in posterior regions of the inferior temporal lobe that were insensitive to whether the decision was held constant or changed between study and test. By contrast, prefrontal cortex showed repetition effects that were sensitive to the exact stimulus-to-decision mapping. Analysis of resting-state functional connectivity revealed that the dissociated repetition effects are embedded within distinct brain systems. Regions that were sensitive to changes in the stimulus correlated with perceptual cortices, whereas the decision changes attenuated activity in regions correlated with middle-temporal regions and a frontoparietal control system. These results thus explain the long-known dissociation between perceptual and conceptual components of priming by revealing how a single experience can separately influence distinct, concurrently active brain systems.

AB The authors aimed to examine central glucocorticoids effects by measuring relative glucose metabolic rate (rGMR) in the hippocampus, amygdala, and anterior cingulate cortex (ACC) and the relationship between amygdala and ACC activity. The participants were male combat veterans with and without PTSD, 52 to 81 years old. The authors utilized randomized, double-blind, placebo-controlled examinations of the rGMR response to 17.5 mg hydrocortisone (HCORT) using 2-Deoxy-2-[(18)F] fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) neuroimaging. Group differences in hemispheric laterality of rGMR were observed following placebo administration, reflecting lower rGMR in the right hippocampus and ventral amygdala, and higher rGMR in the left ventral amygdala in the PTSD+ group compared to the PTSD+ group. HCORT reduced these group differences in laterality. The net effect of HCORT was to restore a normal inverse association between the ACC and amygdala in the PTSD+ group, but disrupt this neural network in the PTSD- group. The magnitude of improvement in working memory correlated with greater hemispheric laterality in the dorsal amygdala following HCORT in both groups. The restorative effects of HCORT on metabolism and working memory provide a rationale for examining the therapeutic benefits of glucocorticoid manipulation in aging PTSD patients.

AB Objective: The purpose was to examine the psychometric properties of the Revised Professional Practice Environment (RPPE) scale.
Background: Despite renewed focus on studying health professionals' practice environments, there are still few reliable and valid instruments available to assist nurse administrators in decision making.
Methods: A psychometric evaluation using a random-sample cross-validation procedure (calibration sample [CS], n = 775; validation sample [VS], n = 775) was undertaken.
Results: Cronbach alpha internal consistency reliability of the total score (r = 0.93 [CS] and 0.92 [VS]), resulting subscale scores (r range: 0.80-0.87 [CS], 0.81-0.88 [VS]), and principal components analyses with Varimax rotation and Kaiser normalization (8 components, 59.2% variance [CS], 59.7% [VS]) produced almost identical results in both samples.
Conclusions: The multidimensional RPPE is a psychometrically sound measure of 8 components of the professional practice environment in the acute care setting and sufficiently reliable and valid for use as independent subscales in healthcare research.

AB Bisphosphonate-related osteonecrosis of the jaw (BRONJ) adversely affects the quality of life, producing significant morbidity in afflicted patients. Strategies for the treatment of patients with, or at risk of, BRONJ were set forth in the American Association of Oral and Maxillofacial Surgeons (AAOMS) Position Paper on Bisphsphonate-Related Osteonecrosis of the jaws (Position Paper) and approved by the Board of Trustees in September 2006.(1) The Position Paper was developed by a Task Force appointed by the Board and composed of clinicians with extensive experience in caring for these patients and basic science researchers. The knowledge base and experience in addressing BRONJ has expanded, necessitating modifications and refinements to the original Position Paper. The Task Force was reconvened in August 2008 to review the 2006 recommendations, appraise the current published data, and revise the Position Paper and recommendations, where indicated. This update contains revisions to the diagnosis and staging and management strategies and highlights the status of basic science research. AAOMS considers it vitally important that this information be disseminated to other dental and medical specialties.

AB The purposes of this report are to 1) summarize the epidemiologic evidence supporting an association between intravenous bisphosphonate (BP) exposure and BP-related osteonecrosis of the jaws (BRONJ), 2) identify measurable risk factors associated with BRONJ, and 3) assess the risk of BRONJ for patients receiving intravenous BPs to manage osteoporosis. The results of this review suggest a compelling, circumstantial association between intravenous BP exposure and BRONJ. The factors consistently associated with an increased risk of BRONJ included intravenous BP exposure in the setting of malignancy and dentoalveolar procedures. Finally, intravenous BP therapy for osteoporosis does not measurably increase the risk of BRONJ among postmenopausal women.

AB Purpose: To evaluate the staining density of CD34, a glycoprotein expressed in hematopoetic precursor and capillary endothelial cells, as a molecular marker for predicting clinical behavior of giant cell tumors.
Materials and Methods: This was a retrospective study of patients with giant cell lesions of the jaws treated over a 15-year period. The primary predictor variable was mean CD34 staining density. The outcome measure was giant cell tumor clinical behavior (aggressive vs nonaggressive). Bivariate analyses were computed to evaluate the association between the predictors and outcome. A receiver-operator characteristic (ROC) curve was used to establish the threshold for a positive diagnostic test. A logistic regression model was used to evaluate the association between the clinical behavior and a positive test. A value of P <= .05 was statistically significant.
Results: The study sample consisted of 32 subjects with a mean age of 24.4 +/- 19.8 years (range 2-83), including 23 females (71.8%), treated for giant cell lesions during the study period. The sample included 26 aggressive lesions and 6 nonaggressive lesions, with mean CD34 staining densities of 5.1 +/- 3.3% and 2.2 +/- 0.7%, respectively (P = .02). Using a CD34 staining level of equal to or more than 2.5% as indicative of a positive test, the sensitivity, specificity, positive and negative predictive values were 0.77, 0.83, 0.95 and 0.45, respectively. CD34 levels of more than 2.5% were significantly associated with aggressive lesions whereas CD 34 levels of less than 2.5% were associated with nonaggressive lesions (odds ratio: 16.7, P = .04).
Conclusions: CD34 staining density levels of more than 2.5% were associated with aggressive giant cell lesions. (C) 2009 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 67:951-956, 2009

TI Clinical Application of Curvilinear Distraction Osteogenesis for
Correction of Mandibular Deformities
SO JOURNAL OF ORAL AND MAXILLOFACIAL SURGERY
LA English
DT Article
AB Purpose: To report the use of a semiburied curvilinear distraction device, with a 3-dimensional (3D) Computed tomography treatment planning system, for correction of mandibular deformities.
Materials and Methods: This was a retrospective evaluation of 13 consecutive patients, with syndromic and nonsyndromic micrognathia, who underwent correction by curvilinear distraction osteogenesis. A 3D computed tomography scan was obtained for each patient and imported into a 3D treatment planning system (Slicer/Osteoplan). Surgical guides were constructed to localize the osteotomy and to drill holes to secure the distractor's proximal and distal footplates to the mandible. Postoperatively, patients were followed by clinical examination and plain radiographs to ensure the desired vector of movement. At end distraction, when possible, a 3D computed tomography scan was obtained to document the final mandibular position.
Results: Of the 13 patients, 8 were females and 5 were males, with a mean age of 11.9 years (range 15 months to 39 years). All 13 underwent bilateral mandibular Curvilinear distraction. Of the 13 patients, 8 were 16 years old or younger and 5 were younger than 6 years of age. The diagnoses included Treacher Collins syndrome (n = 3), Nager syndrome (n = 3), craniofacial microsomia (n = 2), post-traumatic ankylosis (n = 1), and micrognathia (syndromic, n = 3; nonsyndromic, n = 1). The correct distractor placement, vector of movement, and final mandibular position were achieved in 10 of 13 patients. In the other 3 patients, the desired jaw position was achieved by "molding" the regenerate.
Conclusions: The use of a semiburied Curvilinear distraction device, with 3D treatment planning, is a potentially powerful tool to correct complex mandibular deformities. (C) 2009 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 67:996-1008, 2009

AB The knowledge of in vivo anterior cruciate ligament (ACL) deformation is fundamental for understanding ACL injury mechanisms and for improving surgical reconstruction of the injured ACL. This study investigated the relative elongation of the ACL when the knee is subject to no load (< 10 N) and then to full body weight (axial tibial load) at various flexion angles using a combined dual fluoroscopic and magnetic resonance imaging (MRI) technique.
Nine healthy subjects were scanned with MRI and imaged when one knee was subject to no load and then to full body weight using a dual fluoroscopic system (0A degrees-45A degrees flexion angles). The ACL was analyzed using three models: a single central bundle; an anteromedial and posterolateral (double functional) bundle; and multiple (eight) surface fiber bundles.
The anteromedial bundle had a peak relative elongation of 4.4% +/- 3.4% at 30A degrees and that of the posterolateral bundle was 5.9% +/- 3.4% at 15A degrees. The ACL surface fiber bundles at the posterior portion of the ACL were shorter in length than those at the anterior portion. However, the peak relative elongation of one posterolateral fiber bundle reached more than 13% whereas one anteromedial fiber bundle reached a peak relative elongation of only about 3% at 30A degrees of flexion by increasing the axial tibial load from no load to full body weight.
The data quantitatively demonstrated that under external loading the ACL experiences nonhomogeneous elongation, with the posterior fiber bundles stretching more than the anterior fiber bundles.

AB Background: Use of lipid emulsions is parenteral nutrition therapy is an important source of daily energy in substitution of potentially harmful glucose calories when given in excess in the intensive care unit. When added to parenteral nutrition (PN) admixtures as a total nutrient admixture (TNA), the stability and safety of the emulsion may be compromised. Development of a rat model of a stable vs unstable lipid infusion would enable a study of the potential risk. Design: Prospective, randomized, controlled study. Methods: Surgical placement of a jugular venous catheter for the administration of TNAs was performed. Two groups were studied: a stable or s-TNA (n = 16) and an unstable or u-TNA (n = 17) as a 24-hour continuous infusion. Stability of TNAs was determined immediately before and after infusion using a laser-based method approved by the United States Pharmacopeia. Results: Blood levels of aspartate aminotransferase, glutathione-S-transferase, and C-reactive protein were significantly elevated in u-TNA vs s-TNA (P < .05). Also, liver tissue concentrations of malondialdehyde were significantly higher in the u-TNA group (P < .05), and triglyceride tissue levels were also higher in u-TNA and approached statistical significance (P = .077). Conclusions: Unstable lipid infusions over 24 hours produce evidence of hepatic accumulation of fat associated with oxidative stress, liver injury, and a low-level systemic inflammatory response.

AB Purpose: To describe the ocular findings in a series of children with spontaneous resolution of primary congenital glaucoma (PCG).
Methods: The medical records of 356 patients with PCG were reviewed. Nine patients with spontaneous resolution of PCG were studied. Fourteen of 18 eyes possessed evidence of early glaucoma, were found to have normal intraocular pressures, and were clinically classified as having spontaneous resolution of PCG. None of the eyes with spontaneous resolution received surgery or any glaucoma medication.
Results: Spontaneous resolution of PCG in all nine patients was recognized after 4 months of age. At the time of diagnosis, large corneas were observed in all affected eyes and Haab's striae in 10 of 14 eyes. Intraocular pressures were normal in 14 eyes. In all 14 eyes, the anterior chambers were deep, the lenses were clear, and the angles were abnormal with the typical appearance of PCG. The eyes with spontaneous resolution of PCG possessed angle abnormalities that were less severe compared to three fellow eyes that required glaucoma treatments.
Conclusion: The occurrence of spontaneous resolution of PCG in these patients is supported by objective clinical evidence. The explanation for this spontaneous resolution is unknown. Its mechanism could be related to continued postnatal development of the angle structures in eyes possessing milder angle abnormalities. The anterior segment findings in patients with spontaneous resolution of PCG are similar to those of patients with treated PCG, the intraocular pressures are normal, the optic nerve damage is stable, and the filtration angles possess mild or moderate abnormalities.

AB Children and adolescents with attention deficit hyperactivity disorder (ADHD) have high levels of psychiatric comorbidity. The most common types of comorbidities include disruptive behavior, anxiety, and substance use disorders, as well as major depression. When comorbidities are present, impairments in school and family functioning tend to be more severe and persistent than in children who have ADHD alone. Comorbidities to ADHD are likely to go unrecognized in primary pediatric settings because clinicians may not routinely collect behavioral information, and parents are often reluctant to discuss their children's emotional problems with physicians. Although ADHD with a comorbid component is associated with poorer outcomes, many such patients can be treated successfully. Developing improved methods for the identification and appropriate treatment of comorbid conditions in children with ADHD must be a high clinical priority, because intervention can have a significant positive impact on patients' functioning and long-term outcomes.

AB Evidence that intentional self-aggressive behaviors are influenced by social groups comes almost exclusively from nonexperimental retrospective studies which fail to address underlying causal processes. Recently, we conducted a study in which experimentally manipulated group norms were found to directly influence self-aggressive behavior (Sloan, Berman, Zeigler-Hill, Greer, & Mae, 2006). The present study was designed to gain a better understanding of the process by which social groups influence self-aggression. More specifically, we examined the effects of dissenters on the adoption of a self-aggressive group norm. Participants (N = 164) were assigned to one of the following conditions: a unanimous self-aggressive group, a nonunanimous group with a single dissenter in either the first or last position who did not engage in self-aggressive behavior, and a group with no systematic agreement concerning self-aggression. Self-aggression was operationally defined as the use of an extreme shock that was self-administered by the participant within the context of an attention task. Results demonstrated that the adoption of a self-aggressive group norm was significantly weakened by the presence of a dissenter. This effect was moderated by gender such that the presence of a dissenter had a greater impact on the self-aggressive behavior of women than it did for men. Clinical and theoretical implications of these findings are discussed.

AB A case-control study of lung cancer mortality in U.S. railroad workers in jobs with and without diesel exhaust exposure is reanalyzed using a new threshold regression methodology. The Study included 1256 workers who died of lung cancer and 2385 controls who died primarily of circulatory system diseases. Diesel exhaust exposure was assessed using railroad job history from the US Railroad Retirement Board and an industrial hygiene survey. Smoking habits were available from next-of-kin and potential asbestos exposure was assessed by job history review. The new analysis reassesses lung cancer mortality and examines circulatory system disease mortality. jobs with regular exposure to diesel exhaust had a survival pattern characterized by an initial delay in mortality, followed by a rapid deterioration of health prior to death. The pattern is seen in subjects dying of lung cancer, circulatory system diseases, and other causes. The unique pattern is illustrated using a new type of Kaplan-Meier survival plot in which the time scale represents a measure of disease progression rather than calendar time. The disease progression scale accounts for a healthy-worker effect when describing the effects of cumulative exposures on mortality. (C) 2008 Elsevier B.V. All rights reserved.

AB Background. An effective report card system for adverse outcome error analysis following surgery is lacking. We hypothesized that a memorialized database could be used in conjunction with error analysis and management evaluation at Morbidity & Mortality conference to generate individualized report cards for Attending Surgeon and System performance.
Study Design. Prospectively collected data from September 2000 through April 2005 were reported following Morbidity & Mortality review on 1618 adverse outcomes, including :219 deaths, following 29,237 operative procedures, in a complete loop to approximately 60 individual surgeons and responsible system personnel.
Results. A 40% reduction of gross mortality (P<0.001) and 430% reduction of age-adjusted mortality were achieved over 4 years at the Academic Center. Quality issues were identified at a rate three times greater than required by New York State regulations and increased from a baseline 4.96% to 32.7% (odds ratio 1.94; P<0.03) irk cases associated with mortality. A detailed review demonstrated a significant increase (P<0.001) in system errors and physician-related diagnostic and judgment errors associated with mortality highlighted those practices and processes involved, and contrasted the results between academic (43% mortality improvement) and community (no improvement) hospitals.
Conclusions. The findings suggest that structured concurrent data collection combined with non-punitive error-based case review and individualized report cards can be used to provide detailed feedback on surgical performance to individual surgeons and possibly improve clinical outcomes.

AB Background: Data suggest that having high expectations about hearing aids results in better overall outcome. However, some have postulated that excessively high expectations will result in disappointment and thus poor outcome. It has been suggested that counseling patients with unrealistic expectations about hearing aids prior to fitting may be beneficial. Data, however, are mixed as to the effectiveness of such counseling, in terms of both changes in expectations and final outcome.
Purpose: The primary purpose of this study was to determine whether supplementing prefitting counseling with demonstration of real-world listening can (1) alter expectations of new hearing aid users and (2) increase satisfaction over verbal-only counseling. Secondary goals of the study were to examine (1) the relationship between prefitting expectations and postfitting outcome, and (2) the effect of hearing aid fine-tuning on hearing aid outcome.
Research Design: Sixty new hearing aid users were fitted binaurally with Beltone Oria behind-the-ear digital hearing aids. Forty participants received prefitting counseling and demonstration of listening situations with the Beltone AVE (TM) (Audio Verification Environment) system; 20 received prefitting counseling without a demonstration of listening situations. Hearing aid expectations were measured at initial contact and following prefitting counseling. Reported hearing aid outcome was measured after eight to ten weeks of hearing aid use.
Study Sample: Sixty new hearing aid users aged between 55 and 81 years with symmetrical sensorineural hearing loss.
Intervention: Participants were randomly assigned to one of three experimental groups, between which the prefitting counseling and follow-up differed: Group 1 received prefitting counseling in combination with demonstration of listening situations. Additionally, if the participant had complaints about sound quality at the follow-up visit, the hearing aids were fine-tuned using the Beltone AVE system. Group 2 received prefitting counseling in combination with demonstration of listening situations with the Beltone AVE system, but no fine-tuning was provided at follow-up. Group 3 received prefitting hearing aid counseling that did not include demonstration of listening, and the hearing aids were not fine-tuned at the follow-up appointment.
Results: The results showed that prefitting hearing aid counseling had small but significant effects on expectations. The two forms of counseling did not differ in their effectiveness at changing expectations; however, anecdotally, we learned from many participants that that they enjoyed listening to the auditory demonstrations and that they found them to be an interesting listening exercise. The data also show that positive expectations result in more positive outcome and that hearing aid fine-tuning is beneficial to the user.
Conclusions: We conclude that prefitting counseling can be advantageous to hearing aid outcome and recommend the addition of prefitting counseling to address expectations associated with quality of life and self-image. The data emphasize the need to address unrealistic expectations prior to fitting hearing aids cautiously, so as not to decrease expectations to the extent of discouraging and demotivating the patient. Data also show that positive expectations regarding the impact hearing aids will have on psychosocial well-being are important for successful hearing aid outcome.

AB Objective: To compare the efficacy and safety of divalproex extended-release (ER) to placebo in a 28-day double-blind study of bipolar disorder in children and adolescents and evaluate the safety of divalproex ER in a 6-month open-label extension study. Method: In the double-blind study, 150 patients (manic or mixed episode, aged 10-17 years) with baseline Young Mania Rating Scale (YMRS) score of 20 or higher were randomized to once-daily placebo or divalproex ER, which was titrated to clinical response or serum valproate concentration of 80 to 125 mu g/mL. Sixty-six patients enrolled in the extension study. Results: In the double-blind study, a treatment effect was not observed with divalproex ER based on change in mean YMRS score (divalproex ER -8.8 [n=74]; placebo -7.9 [n= 70]) or secondary measures. Divalproex was similar to placebo based on incidence of adverse events. Four subjects treated with divalproex ER and three treated with placebo discontinued because of adverse events. Mean ammonia levels increased in the divalproex ER group, but only one patient was symptomatic. In the long-term study, YMRS scores decreased modestly (2.2 points from baseline). The most common adverse events were headache and vomiting. Conclusions: The results of the study do not provide support for the use of divalproex ER in the treatment of youths with bipolar I disorder, mixed or manic state. Further controlled trials are required to confirm or refute the findings from this study. J. Am. Acad. Child Adolesc. Psychiatry, 2009;48(5):519-532.

AB Spitzoid lesions are diagnostically problematic because of it deceptive morphology and indeterminate behavior. The most problematic are atypical Spitz tumors whereby distinction from melanoma may be difficult. We have recognized it melanocytic lesion with a reproducible histomorphology, demonstrating characteristic demographic features, namely a predilection to involve younger female patients and common occurrence on the thigh. We have designated this lesion as the superficial atypical Spitz tumor and have encountered 27 cases. We believe that these lesions overlap histomorphologically with higher-grade dysplastic nevi and de novo intraepidermal epitheloid melanocytic dysplasia. We identified 19 additional cases that appear to represent transition into malignant melanoma of superficial spreading type arising in a background of the superficial atypical Spitz tumor. A limitation is that complete medical histories were not obtained for all patients. In conclusion, there exists a distinct subset of Spitz tumors that we designate as the superficial atypical Spitz tumor in which there is inherent dysplasia including lesions that evolve into melanoma of superficial spreading type.

COMMUNITY; SEVERITY; VALIDITY
AB Background: Although many health care organizations require routine pain screening (eg, "5th vital sign") with the 0 to 10 numeric rating scale (NRS), its accuracy has been questioned; here we evaluated its accuracy and potential causes for error.
Methods: We randomly surveyed veterans and reviewed their charts after outpatient encounters at 2 hospitals and 6 affiliated community sites. Using correlation and receiver operating characteristic analysis, we compared the routinely measured "5th vital sign" (nurse-recorded NRS) with a research-administered NRS (research-recorded NRS) and the Brief Pain Inventory (BPI).
Results: During 528 encounters, nurse-recorded NRS and research-recorded NRS correlated moderately (r = 0.627), as did nurse-recorded NRS and BPI severity scales (r = 0.613 for pain during the last 24 hours and r = 0.588 for pain during the past week). Correlation with BPI interference was lower (r = 0.409). However, the research-recorded NRS correlated substantially with the BPI severity during the past 24 hours (r = 0.870) and BPI severity during the last week (r = 0.840). Receiver operating characteristic analysis showed similar results. Of the 98% of cases where a numeric score was recorded, 51% of patients reported their pain was rated qualitatively, rather than with a 0 to 10 scale, a practice associated with pain underestimation (chi(2) = 64.04, P < .001).
Conclusion: Though moderately accurate, the outpatient "5th vital sign" is less accurate than under ideal circumstances. Personalizing assessment is a common clinical practice but may affect the performance of research tools such as the NRS adopted for routine use. (J Am Board Fam Med 2009;22:291-8.)

AB BACKGROUND: Neoadjuvant aromatase Inhibitor therapy has been reported to improve Surgical Outcomes for postmenopausal women with clinical stage II or III hormone receptor-positive breast cancer. A multicenter phase II clinical trial was conducted to investigate the value of this approach for US surgical practice.
STUDY DESIGN: One hundred fifteen postmenopausal women with >2 cm, estrogen receptor (ER) or progesterone receptor (PgR)-positive breast cancer were enrolled in a trial of 16 to 24 weeks of letrozole 2.5 mg daily before operation.
RESULTS: One hundred six patients were eligible for primary analysis, 96 underwent operations, 7 received chemotherapy after progressive disease, and 3 did not undergo an operation. Baseline Surgical status was marginal for breast-conserving surgery (BCS) in 48 (450/8), 47 were definitely ineligible for BCS (44%), and 11 were Inoperable by standard mastectomy (10%). Overall Response Evaluation Criteria In Solid Tumors clinical response rate in the breast was 62%, with 12% experiencing progressive disease. Fifty percent underwent BCS, including 30 of 46 (65%) patients who were initially marginal for BCS and 15 of 39 (38%) patients who were Initially ineligible for BCS. All 11 inoperable patients successfully underwent operations, including 3 (27%) who had BCS. Nineteen percent of patients undergoing mastecromy had a pathologic T1 tumor, Suggesting that some highly responsive tumors were overtreated surgically.
CONCLUSIONS: Neoadjuvant aromatase inhibitor improves operability and facilitates BCS, but there was considerable variability in responsiveness. Better techniques to predict response, determine residual tumor burden before operation, and greater willingness to attempt BCS in responsive patients Could additionally improve the rate of successful BCS.

AB Sleep-related disorders are most prevalent in the older adult population. A high prevalence of medical and psychosocial comorbidities and the frequent use of multiple medications, rather than aging per se, are major reasons for this. A major concern, often underappreciated and underaddressed by clinicians, is the strong bidirectional relationship between sleep disorders and serious medical problems in older adults. Hypertension, depression, cardiovascular disease, and cerebrovascular disease are examples of diseases that are more likely to develop in individuals with sleep disorders. Conversely, individuals with any of these diseases are at a higher risk of developing sleep disorders. The goals of this article are to help guide clinicians in their general understanding of sleep problems in older persons, examine specific sleep disorders that occur in older persons, and suggest evidence- and expert-based recommendations for the assessment and treatment of sleep disorders in older persons. No such recommendations are available to help clinicians in their daily patient care practices. The four sections in the beginning of the article are titled, Background and Significance, General Review of Sleep, Recommendations Development, and General Approach to Detecting Sleep Disorders in an Ambulatory Setting. These are followed by overviews of specific sleep disorders: Insomnia, Sleep Apnea, Restless Legs Syndrome, Circadian Rhythm Sleep Disorders, Parasomnias, Hypersomnias, and Sleep Disorders in Long-Term Care Settings. Evidence- and expert-based recommendations, developed by a group of sleep and clinical experts, are presented after each sleep disorder.

AB To investigate financial capacity in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) using a clinician interview approach.
Cross-sectional.
Tertiary care medical center.
Healthy older adults (n=75) and patients with amnestic MCI (n=58), mild AD (n=97), and moderate AD (n=31).
The investigators and five study physicians developed a conceptually based, semistructured clinical interview for evaluating seven core financial domains and overall financial capacity (Semi-Structured Clinical Interview for Financial Capacity; SCIFC). For each participant, a physician made capacity judgments (capable, marginally capable, or incapable) for each financial domain and for overall capacity.
Study physicians made more than 11,000 capacity judgments across the study sample (N=261). Very good interrater agreement was obtained for the SCIFC judgments. Increasing proportions of marginal and incapable judgment ratings were associated with increasing disease severity across the four study groups. For overall financial capacity, 95% of physician judgments for older controls were rated as capable, compared with 82% for patients with MCI, 26% for patients with mild AD, and 4% for patients with moderate AD.
Physicians and other clinicians can reliably evaluate financial capacity in cognitively impaired older adults using a relatively brief, semistructured clinical interview. Patients with MCI have mild impairment in financial capacity, those with mild AD have emerging global impairment, and those with moderate AD have advanced global impairment. Patients with MCI and their families should proactively engage in financial and legal planning, given these patients' risk of developing AD and accelerated loss of financial abilities.

SO JOURNAL OF THE AMERICAN MEDICAL INFORMATICS ASSOCIATION

DT Article
ID ERRORS
AB Errors associated with medication documentation account for a substantial fraction of preventable medical errors. Hence, the Joint Commission has called for the adoption of reconciliation strategies at all United States healthcare institutions. Although studies suggest that reconciliation tools can reduce errors, it remains unclear how best to implement systems and processes that are reliable and sensitive to clinical workflow. The authors designed a primary care process that Supported reconciliation without compromising clinic efficiency. This manuscript describes the design and implementation of Automated Patient History Intake Device (APHID): ambulatory check-in kiosks that allow patients to review the names, dosage, frequency, and Pictures of their medications before their appointment. Medication lists are retrieved from the electronic health record and patient updates are captured and reviewed by providers during the clinic session. Results from the roll-in phase indicate the device is easy for patients to use and integrates well with clinic workflow. J Am Med Inform Assoc. 2009;16:300-304. DOI 10.1197/jamia.M2642.

TI Sensitizing the Slit Diaphragm with TRPC6 Ion Channels
SO JOURNAL OF THE AMERICAN SOCIETY OF NEPHROLOGY
LA English
DT Article
ID FOCAL SEGMENTAL GLOMERULOSCLEROSIS; NEPHRIN; KIDNEY; ACTIN; FYN
AB Physiologic permeability of the glomerular capillary depends on the normal structure of podocyte foot processes forming a functioning slit diaphragm in between. Mutations in several podocyte genes as well as specific molecular pathways have been identified as the cause for progressive kidney failure with urinary protein loss. Podocyte injury is a hallmark of glomerular disease, which is generally displayed by the rearrangement of the podocyte slit diaphragm and the actin cytoskeleton. Recent studies demonstrate a unique role for the Ca(2+)-permeable ion channel protein TRPC6 as a regulator of glomerular ultrafiltration. In both genetic and acquired forms of proteinuric kidney disease, dysregulation of podocyte TRPC6 plays a pathogenic role. This article illustrates how recent findings add to emerging concepts in podocyte biology, particularly mechanosensation and signaling at the slit diaphragm.

AB Large arteries commonly become stiff in kidney failure, but few studies have investigated arterial stiffness in earlier stages of kidney disease. We evaluated the association between kidney function and aortic pulse wave velocity (aPWV) and its potential modification by race, diabetes, or coronary heart disease in older adults. We measured aPWV in 2468 participants in the Health Aging and Body Composition (Health ABC) study; mean age was 73.7 yr, 40% were black, and 24% had diabetes. After categorizing kidney function into three groups on the basis of cystatin C level, multivariable analysis revealed that the medium and high cystatin C groups associated with a 5.3% (95% confidence interval 0.8 to 10.0%) and 8.0% (95% confidence interval 2.2 to 14.1%) higher aPWV than the low cystatin C group; however, chronic kidney disease, as defined by estimated GFR <60 ml/min per 1.73 m(2), did not significantly associate with aPWV. We did not identify interactions between cystatin C and race, diabetes, or coronary heart disease. In conclusion, stiffness of large arteries, a major risk factor for cardiovascular disease, may partially mediate the association between cystatin C and cardiovascular risk in older adults.

AB Animal studies have suggested a potential role for regulatory T cells (Tregs) in allograft tolerance, but these FOXP3+ cells seem to be an inherent component of acute rejection (AR) in human recipients of renal transplants. The balance between regulatory cells and effector/cytotoxic cells may determine graft outcome; this balance has not been described for chronic allograft injury. We investigated the expression of key regulatory, effector, and cytotoxic transcripts (i.e., FOXP3, T-bet, and granzyme B, respectively) in the grafts and peripheral blood of long-term-surviving renal transplant patients. We found that, whereas neither intragraft nor peripheral blood FOXP3 or T-bet mRNA could distinguish between rejection and nonrejection status, granzyme B (GrzB) mRNA could: It was significantly increased in the graft and significantly decreased in the peripheral blood of patients with chronic antibody-mediated rejection (CAMR). Quantifying peripheral blood GrzB mRNA demonstrated potential to aid in the noninvasive diagnosis of CAMR. In summary, these data affirm GrzB as a marker not only for AR but also for CAMR. In addition, we identified several previously unreported clinical or demographic factors influencing regulatory/effector/cytotoxic profiles in the peripheral blood, highlighting the necessity to consider confounding variables when considering the use of potential biomarkers, such as FOXP3, for diagnosis or prognosis in kidney transplantation.

AB Plasma gelsolin (pGSN) binds actin and bioactive mediators to localize inflammation. Low pGSN correlates with adverse outcomes in acute injury, whereas administration of recombinant pGSN reduces mortality in experimental sepsis. We found that mean pGSN levels of 150 patients randomly selected from 10,044 starting chronic hemodialysis were 140 +/- 42 mg/L, 30 to 50% lower than levels reported for healthy individuals. In a larger sample, we performed a case-control analysis to evaluate the relationship of pGSN and circulating actin with mortality; pGSN levels were significantly lower in 114 patients who died within 1 yr of dialysis initiation than in 109 survivors (117 +/- 38 mg/L versus 147 +/- 42 mg/L, P < 0.001). pGSN levels had a graded, inverse relationship with 1-yr mortality, such that patients with pGSN < 130 mg/L experienced a > 3-fold risk for mortality compared with those with pGSN >= 150 mg/L. The 69% of patients with detectable circulating actin had lower pGSN levels than those without (127 +/- 45 mg/L versus 141 +/- 36 mg/L, P = 0.026). Compared with patients who had elevated pGSN and no detectable actin, those with low pGSN levels and detectable actin had markedly increased mortality (odds ratio 9.8, 95% confidence interval 2.9 to 33.5). Worsening renal function correlated with pGSN decline in 53 subjects with CKD not on dialysis. In summary, low pGSN and detectable circulating actin identify chronic hemodialysis patients at highest risk for 1-yr mortality.

AB Introduction: Exercise improves functional outcome and symptoms for certain cancer populations, but the feasibility, efficacy, and safety of structured exercise in patients with lung cancer is unknown. In this Study, we examined the feasibility of a hospital-based exercise program for patients with advanced non-small cell lung cancer.
Methods: This study included patients with newly diagnosed advanced stage non-small cell lung cancer and Eastern Cooperative Oncology Group performance status 0-1. A physical therapist facilitated twice-weekly sessions of aerobic exercise and weight training over an 8-week period. The primary end point was feasibility of the intervention, defined as adherence to the exercise program. Secondary endpoints included functional capacity, measured by the 6-minute walk test and Muscle strength, as well as quality Of life, lung cancer symptoms and fatigue, measured by the Functional Assessment of Cancer Therapy-lung and Functional Assessment of Cancer Therapy-fatigue scales.
Results: Between October 2004 and August 2007, 25 patients enrolled in the study. All participants received anticancer therapy during the Study period. Twenty patients (80%) underwent the baseline physical therapy evaluation. Eleven patients (44%) completed all 16 sessions. An additional 6 patients attended at least 6 sessions (range, 6-15), and 2 patients only attended one session. Study completers experienced a significant reduction in lung cancer symptoms and no deterioration in their 6-minute walk test or muscle strength.
Conclusions: Although the majority of participants attempted the exercise program, less than half were able to complete the intervention. Those who completed the program experienced an improvement in their lung cancer symptoms. Community-based or briefer exercise interventions may be more feasible in this population.

AB Background Reperfusion injury is a significant complication of the management of ST-elevation MI (STEMI). INO-1001 is a potent inhibitor of poly(ADP-ribose) polymerase (PARP), a mediator of oxidant-induced myocyte dysfunction during reperfusion. Methods & results We assessed the safety and pharmacokinetics of INO-1001 in a randomized, placebo-controlled, single-blind, dose-escalating trial in 40 patients with STEMI undergoing primary percutaneous coronary intervention within 24 h of onset. INO-1001 was well-tolerated. A trend toward more frequent transaminitis was observed with 800 mg. Plasma from INO1001-treated patients reduced in vitro PARP activity > 90% at all doses. Serial C-reactive protein and IL-6 levels showed a trend toward blunting of inflammation with INO-1001. The apparent median terminal half-life (t(1/2)) of INO-1001 was 7.5 (25th, 75th: 5.9, 10.2) h. Conclusions The results from this first trial of INO-1001 in STEMI support future investigation of INO-1001 as a novel treatment for reperfusion injury.

AB Purpose: Androgen deprivation therapy has a variety of well recognized adverse effects including vasomotor flushing, loss of libido, fatigue, gynecomastia, anemia and osteoporosis. This review focuses on the more recently described metabolic complications of androgen deprivation therapy including obesity, insulin resistance and lipid alterations as well as the association of androgen deprivation therapy with diabetes and cardiovascular disease.
Materials and Methods: We reviewed the medical literature using the PubMed (R) search terms prostate cancer, androgen deprivation therapy, gonadotropin-releasing hormone agonists, obesity, insulin resistance, lipids, diabetes, cardiovascular disease and myocardial infarction. We provide a focused review and our perspective on the relevant literature.
Results: Androgen deprivation therapy decreases lean mass and increases fat mass. It also decreases insulin sensitivity while increasing low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglycerides. Consistent with these adverse metabolic effects, androgen deprivation therapy may be associated with a greater incidence of diabetes and cardiovascular disease. Some of these androgen deprivation therapy related metabolic changes (obesity, insulin resistance and increased triglycerides) overlap with features of the metabolic syndrome. However, in contrast to the metabolic syndrome, androgen deprivation therapy increases subcutaneous fat and high density lipoprotein cholesterol.
Conclusions: Androgen deprivation therapy increases obesity, decreases insulin sensitivity and adversely alters lipid profiles. It may be associated with a greater incidence of diabetes and cardiovascular disease. The benefits of androgen deprivation therapy should be weighed against these and other potential harms. Little is known about the optimal strategy to mitigate the adverse metabolic effects of androgen deprivation therapy. Thus, we recommend an emphasis on existing strategies for screening and treatment that have been documented to reduce the risk of diabetes and cardiovascular disease in the general population.

TI Increased Startle Responses in Interstitial Cystitis: Evidence for
Central Hyperresponsiveness to Visceral Related Threat
SO JOURNAL OF UROLOGY
LA English
DT Article
DE cystitis; interstitial; sensory gating; startle reaction; reflex
ID ANXIETY DISORDERS; PELVIC PAIN; FEAR; AMYGDALA; HYPERSENSITIVITY; INDEX;
IBS
AB Purpose: Hypersensitivity to visceral stimuli in interstitial cystitis/painful bladder syndrome may result from enhanced responsiveness of affective circuits (including the amygdala complex) and associated central pain amplification. Potentiation of the eyeblink startle reflex under threat is mediated by output from the amygdala complex and, therefore, represents a noninvasive marker to study group differences in responsiveness in this brain circuit.
Materials and Methods: Acoustic startle responses were examined in female patients with interstitial cystitis/painful bladder syndrome (13) and healthy controls (16) during context threat (application of muscle stimulation electrodes to the lower abdomen overlying the bladder), and cued conditions for safety (no stimulation possible), anticipation and imminent threat of aversive abdominal stimulation over the bladder.
Results: Patients showed significantly greater startle responses during nonimminent threat conditions (baseline, safe and anticipation periods) while both groups showed similar robust startle potentiation during the imminent threat condition. Higher rates of anxiety and depression symptoms in the patient group did not account for the group differences in startle reflex magnitude.
Conclusions: Compared to controls, female patients with interstitial cystitis/painful bladder syndrome showed increased activation of a defensive emotional circuit in the context of a threat of abdominal pain. This pattern is similar to that previously reported in patients with anxiety disorders as well as those with irritable bowel syndrome. Since these circuits have an important role in central pain amplification related to affective and cognitive processes, these results support the hypothesis that the observed abnormality may be involved in the enhanced perception of bladder signals associated with interstitial cystitis/painful bladder syndrome.

TI Wound Dehiscence or Failure to Heal following Venous Access Port
Placement in Patients Receiving Bevacizumab Therapy
SO JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY
LA English
DT Article
ID INTERVENTIONAL RADIOLOGISTS
AB PURPOSE: To determine the incidence of wound dehiscence or failure to heal after port placement in patients receiving bevacizumab therapy. A hypothesis was tested that the mean interval between bevacizumab administration and port placement was shorter in patients who had dehiscence than in those who did not.
MATERIALS AND METHODS: Medical records of all patients who had venous access ports placed from July 2006 through December 2007 were retrospectively reviewed. A total of 195 ports were placed in 189 patients (106 men) who were treated with bevacizumab within 120 days of port placement. The incidence of wound dehiscence and the significance of dose timing relative to port placement in these patients were calculated.
RESULTS: Six of 195 ports (3.1%) were associated with wound dehiscence requiring port removal. The mean interval between bevacizumab dosing and port placement in patients without dehiscence (n = 189) was 16.9 days. The mean interval in patients with dehiscence (n = 6) was 10.8 days. A two-tailed Wilcoxon test was performed, which yielded a P value of .0150. A statistically significant difference in the mean interval between bevacizumab dosing and port placement exists between patients with dehiscence and those without.
CONCLUSIONS: Wound dehiscence after port placement was related to timing of bevacizumab therapy. Patients receiving bevacizumab within 10 days of port placement had a higher incidence of wound dehiscence.

AB PURPOSE: To assess the potential of macroembolization, the authors compared the downstream particulate profile generated with use of two thrombectomy devices, a 20-kHz ultrasound-based sonothrombolytic (ST) device and a rotating dispersion wire (RDW).
MATERIALS AND METHODS: An arterial flow model was pressurized to 100 mm Hg and perfused with 1,000 mL/min normal saline. Tubing containing 7-mm x 30-cm bovine thrombus proximal to a 75% stenosis was inserted distal to a nonstenosed bypass. The effluent was passed successively through 1,000-, 500-, and 200-mu m filters and a particle analyzer. The ST device and RDW were activated for 10 and 15 minutes, respectively, in randomized sequences of experimental sets with and without the use of 10-mg tissue-type plasminogen activator (tPA). Results are expressed as means and standard deviations of fraction of lysed clot in each category.
RESULTS: The ST device produced significantly fewer particulates larger than 1,000 mu m (1.3% +/- 1.4) than did the RDW (16.8% +/- 8.4, P < .001) and significantly more particulates smaller than 10 mu m (90.7% +/- 7.6) than did the RDW (73.9% +/- 9.5; P <.001) at comparable thrombolytic efficacy (P =.982) and without significant effect from tPA (P =.988). There were no significant differences between particles measuring 500-1,000 mu m (ST device: 0.3% +/- 0.3, RDW: 0.4% +/- 0.3; P =.653) and those measuring 10-199 mu m (ST device: 7.5% +/- 7.5, RDW: 8.6% +/- 3.8; P =.624). The amount of particles on the 200-mu m filter after RDW activation (0.4% 0.3) exceeded those trapped after use of the ST device (0.1% +/- 0.1, P =.007) but contributed relatively little overall.
CONCLUSIONS: In this in vitro model, the use of the ST device resulted in fewer large particulates than did the use of the RDW, with more clots being reduced to less than 10 mu m.

AB Chemotherapy-resistant colon carcinoma metastases to a patient's right hepatic lobe progressed after right lobar radioembolization with yttrium-90. The metastasis-free left lobe had adequate volume as a future liver remnant. Repeat right lobar radioembolization with supratherapeutic activity of (90)y caused shrinking of the tumors and the right lobe with no adverse outcome. With an adequate tumor-free future liver remnant, one hepatic lobe bearing a large tumor burden may be administered supratherapeutic activity of (90)Y, risking lobar ablation for greater probability of tumor eradication. This is analogous to hepatic lobectomy. This case is presented as a proof of principle.

AB Objective: To validate the Glasgow Aneurysm Score (GAS) in patients with ruptured abdominal aortic aneurysms (AAAs) treated with endovascular repair or open surgery and to update the GAS so that it predicts 30-day mortality for patients with ruptured AAA treated with endovascular repair or open surgery.
Methods: In a multicenter prospective observational study, 233 consecutive patients with ruptured AAAs were evaluated; 32 patients did not survive to repair and statistical analysis was performed using collected data on 201 patients. All patients who were treated with endovascular repair (n = 58) or open surgery (n = 143) were included. The GAS was calculated for each patient. The area under the receiver operating characteristics curve (AUC) was used to indicate discriminative ability. We tested for interactions between risk factors and the procedure performed. The GAS was updated to predict 30-day mortality after endovascular repair or open surgery in patients with ruptured AAAs using logistic regression analysis.
Results: Thirty-day mortality was 15/58 (26%) for patients treated with endovascular repair and 57/143 (40%) for patients treated with open surgery (P = .06). The AUC for GAS was 0.69. No relevant interactions were found. The updated prediction rule (AUC = 0.70) clan be calculated with the following formula: + 7 for open surgery + age in years + 17 for shock + 7 for myocardial disease + 10 for cerebrovascular disease + 14 for renal insufficiency.
Conclusion: We showed limited discriminative ability of the GAS and therefore updated the GAS by adding the type of procedure performed. This updated prediction rule predicts 30-day mortality for patients with ruptured AAAs treated with endovascular repair or open surgery. (J Vase Surg 2009;49:1093-9.)

AB Objective: To characterize the inflammatory and coagulopathic response after endovascular thoracoabdominal aortic aneurysm (TAAA) repair and to evaluate the effect of the response on postoperative renal function.
Methods. From July 2005 to June 2008, 42 patients underwent elective endovascular repair of a TAAA using custom designed multi-branched stent-grafts at a single academic institution. Four patients were excluded from the analysis. White blood cell count (WBC), platelet count, prothrombin time (PT), and creatinine were measured in all patients. In the last nine patients, interleukin-6 (IEL-6), protein C, Factor V, cl-dimers, cystatin C, and neutrophil gelatinase-associated lipocatin (NGAL) levels were also measured. Change in lab values were expressed as a percentage of baseline values.
Results. The 30-day mortality rate was 5% (2/38). All patients (n = 38) had a higher WBC (mean +/- SD: 139 +/- 80%, P < .0001), lower platelet count (56 +/- 15%, P < .0001), and higher PT (median: 17%, Interquartile range (IQR) 12%-22%, P < .0001) after stent-graft insertion. Twelve of 38 patients (32%) developed postoperative acute renal insufficiency (>50% rise in creatinine). Patients with renal insufficiency had significantly larger changes in WBC (178 +/- 100% vs 121 +/- 64%, P = .04) and platelet count (64 +/- 17% vs 52 +/- 12%, P = .02) compared with those without renal insufficiency. All patients (n = 9) had significant increases in NGAL (182 +/- 115%, P = .008) after stent-graft insertion. Six of nine patients (67%) had increased cystatin C (35 +/- 43%, P = .04) after stent-graft insertion, with a greater rise in those with postoperative renal insufficiency (87 +/- 32% vs 8 +/- 13%, P = .02). IEL-6 levels were markedly increased in all patients (n = 9) after repair (9840 +/- 6160%, P = .008). Protein C (35 +/- 10%, P = .008) and Factor V levels (28 +/- 20%, P = .008) were uniformly decreased, while d-dimers were elevated after repair in all patients (310 +/- 213%, P = .008).
Conclusions. Leukocytosis and thrombocytopenia were uniform following endovascular TAAA repair, and the severity of the response correlated with post-operative renal dysfunction. Elevation of a sensitive marker of renal injury (NGAL) suggests that renal injury may occur in all patients after stent-graft insertion. (J Vasc Surg 2009;49:1140-6.)

AB The human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein trimer consists of gp120 and gp41 subunits and undergoes a series of conformational changes upon binding to the receptors, CD4 and CCR5/CXCR4, that promote virus entry. Surprisingly, we found that the envelope glycoproteins of some HIV-1 strains are functionally inactivated by prolonged incubation on ice. Serial exposure of HIV-1 to extremes of temperature, followed by expansion of replication-competent viruses, allowed selection of a temperature-resistant virus. The envelope glycoproteins of this virus resisted cold inactivation due to a single passage-associated change, H66N, in the gp120 exterior envelope glycoprotein. Histidine 66 is located within the gp41-interactive inner domain of gp120 and, in other studies, has been shown to decrease the sampling of the CD4-bound conformation by unliganded gp120. Substituting asparagine or other amino acid residues for histidine 66 in cold-sensitive HIV-1 envelope glycoproteins resulted in cold-stable phenotypes. Cold inactivation of the HIV-1 envelope glycoproteins occurred even at high pH, indicating that protonation of histidine 66 is not necessary for this process. Increased exposure of epitopes in the ectodomain of the gp41 transmembrane envelope glycoprotein accompanied cold inactivation, but shedding of gp120 did not. An amino acid change in gp120 (S375W) that promotes the CD4-bound state or treatment with soluble CD4 or a small-molecule CD4 mimic resulted in increased cold sensitivity. These results indicate that the CD4-bound intermediate of the HIV-1 envelope glycoproteins is cold labile; avoiding the CD4-bound state increases temperature stability.

TI HLA Footprints on Human Immunodeficiency Virus Type 1 Are Associated

VACCINE DESIGN; VIRAL LOAD; ESCAPE
AB The selection of escape mutations has a major impact on immune control of infections with viruses such as human immunodeficiency virus (HIV). Viral evasion of CD8(+) T-cell responses leaves predictable combinations of escape mutations, termed HLA "footprints." The most clearly defined footprints are those associated with HLA alleles that are linked with successful control of HIV, such as HLA-B*57. Here we investigated the extent to which HLA footprint sites in HIV type 1 (HIV-1) are associated with viral evolution among and within clades. First, we examined the extent to which amino acid differences between HIV-1 clades share identity with sites of HLA-mediated selection pressure and observed a strong association, in particular with respect to sites of HLA-B selection (P < 10(-6)). Similarly, the sites of amino acid variability within a clade were found to overlap with sites of HLA-selected mutation. Second, we studied the impact of HLA selection on interclade phylogeny. Removing the sites of amino acid variability did not significantly affect clade-specific clustering, reflecting the central role of founder effects in establishing distinct clades. However, HLA footprints may underpin founder strains, and we show that amino acid substitutions between clades alter phylogeny, underlining a potentially substantial role for HLA in driving ongoing viral evolution. Finally, we investigated the impact of HLA selection on within-clade phylogeny and demonstrate that even a single HLA allele footprint can result in significant phylogenetic clustering of sequences. In conclusion, these data highlight the fact that HLA can be a strong selection force for both intra- and interclade HIV evolution at a population level.

AB Understanding pediatric voice development and laryngeal pathology is predicated on a detailed knowledge of the microanatomy of the layered structure of the vocal fold. Our current knowledge of this microanatomy and its temporal evolution is limited by the lack of pediatric specimen availability. By providing the capability to image pediatric vocal folds in vivo, a noninvasive microscopy technique could greatly expand the existing database of pediatric laryngeal microanatomy and could furthermore make longitudinal Studies possible. A variety of natural-contrast optical imaging technologies, including optical frequency domain imaging (OFDI), full-field optical coherence microscopy (FF-OCM), and spectrally encoded confocal microscopy (SECM) have been recently developed for noninvasive diagnosis in adult patients. In this paper, we demonstrate the potential of these three techniques for laryngeal investigation by obtaining images of excised porcine vocal fold samples. In our study, OFDI allowed visualization of the vocal fold architecture deep within the tissue, from the superficial mucosa to the vocalis muscle. The micron-level resolution of SECM allowed investigation of cells and extracellular matrix fibrils from the superficial mucosa to the intermediate layer of the lamina propria (LP) (350 mu m penetration depth). The large field of view (Lip to 700 Am), penetration depth (up to 500 mu m), and resolution (2 X 2 X 1 mu m [X X Y X Z]) of FF-OCM enabled comprehensive three-dimensional evaluation of the layered structure of the LP. Our results Suggest that these techniques provide important and complementary cellular and structural information, which may be useful for investigating pediatric vocal fold maturation in vivo.

AB Background: Previous studies have shown that women have decreased survival and receive fewer cardiac procedures after acute myocardial infarction (AMI) compared with men, raising concerns for sexual bias in provision of care. The objective of this study is to describe clinical characteristics, treatment, and survival in women veterans compared with men after admission to VA hospitals for AMI.
Methods: This is a retrospective inception cohort study using data drawn from the VA Cardiac Care Follow-up Clinical Study, describing patients admitted for AMI to VA hospitals from October 1, 2003 to March 31, 2005. Subjects were followed for 1 year.
Results: There were 236 women and 13,259 men admitted during the study period to VA hospitals with AMI. Women were less likely to have a history of heart failure compared with men (18.2% of women vs. 27.2% of men, p = 0.002) and previous coronary artery bypass grafting (CABG) (11.4% of women vs. 19.6% of men, p=0.002). Diagnostic cardiac catheterization was similar in women and men (36.9% and 34.9%, p = 0.539). Crude in-hospital mortality was 4.2% for women and 7.6% for men (p=0.051). After adjusting for comorbidities and treatment variables, in-hospital mortality was not significantly different for women compared with men (hazard ratio [HR] 0.82, 95% confidence interval [CI] 0.60-1.12).
Conclusions: Women veterans receive a level of care similar to men veterans for MI treated in VA hospitals. Differences in mortality between women and men were not significant and do not suggest that women fare worse.

AB Cardiovascular mortality is especially high among dialysis patients with diabetes, as is morbidity due to protein energy wasting. Given that both of these factors may be decreased by thiazolidinedione treatment, we studied the effect of thiazolidinedione use on survival among chronic dialysis patients in a national cohort of 5290 incident dialysis patients with diabetes. Thiazolidinedione use was assessed according to prescription data, and the analyses were stratified based on insulin use due to observed interaction. In the primary analysis, thiazolidinedione treatment was associated with significantly lower all-cause mortality among insulin-free but not insulin-requiring subjects, with adjusted hazards ratios of 0.53 (0.31-0.89) and 0.82 (0.46-1.47) respectively. Sensitivity analyses found the findings to be robust with respect to confounding by indication, severity of the diabetes, potential reverse causality, and time varying exposure patterns. The mechanism of this decline in all-cause mortality will need to be examined after these studies are confirmed.

AB Objectives: Proteins in perilymph may alter the delivery profile of implantable intracochlear drug delivery systems through biofouling. Knowledge of protein composition will help anticipate interactions with delivered agents.
Study Design: Analysis of mouse perilymph.
Methods: Protein composition of perilymph and cerebrospinal fluid (CSF) was analyzed using a capillary liquid chromatography-mass spectrometry-based iTRAQ quantitative proteomics approach. We searched against a mouse subset of the Uniprot FASTA protein database. We sampled perilymph from the apex of the mouse cochlea to minimize CSF contamination.
Results: More than 50 explicit protein isoforms were identified with very high confidence. iTRAQ reporter ions allowed determination of relative molar amounts of proteins between perilymph and CSF. Protein in perilymph was almost three times more concentrated than in CSF. More than one-third of the proteins in perilymph comprised protease inhibitors, with serpins being the predominant group. Apolipoproteins constituted 16%. Fifteen percent of the proteins were enzymes. Albumin was the most abundant single protein (14%). Proteins with relatively high perilymph/CSF ratios included broad-spectrum protease inhibitors and apolipoproteins.
Discussion: Some proteins found in perilymph, such as albumin and HMW kininogen, have been implicated in biofouling through adsorption to device materials. The relatively large quantities of apolipoprotein and albumin may serve as a reservoir for acidic and lipophillic drugs. Alpha-2-glycoprotein can bind basic drugs.
Conclusions: Perilymph is similar in protein composition to CSF, though amounts are 2.8 times higher. Protease inhibitors comprise the largest category of proteins.

AB Acute coronary events such as myocardial infarction are frequently caused by the rupture of unstable atherosclerotic plaque. Collagen plays a key role in determining plaque stability. Methods to measure plaque collagen content are invaluable in detecting unstable atherosclerotic plaques. Recently, novel coherent laser-based imaging techniques, such as polarization-sensitive optical coherence tomography (PSOCT) and laser speckle imaging (LSI) have been investigated, and they provide a wealth of information related to collagen content and plaque stability. Additionally, given their potential for intravascular use, these technologies will be invaluable for improving our understanding of the natural history of plaque development and rupture and, hence, enable the detection of unstable plaques. In this article we review recent developments in these techniques and potential challenges in translating these methods into intra-arterial use in patients.

AB We found that composition of cell subsets within the CD34+ cell population is markedly altered in chronic phase (CP) chronic myeloid leukemia (CML). Specifically, proportions and absolute cell counts of common myeloid progenitors (CMP) and megakaryocyte-erythrocyte progenitors (MEP) are significantly greater in comparison to normal bone marrow whereas absolute numbers of hematopoietic stem cells (HSC) are equal. To understand the basis for this, we performed gene expression profiling (Affymetrix HU-133A 2.0) of the distinct CD34+ cell subsets from six patients with CP CML and five healthy donors. Euclidean distance analysis revealed a remarkable transcriptional similarity between the CML patients' HSC and normal progenitors, especially CMP. CP CML HSC were transcriptionally more similar to their progeny than normal HSC to theirs, suggesting a more mature phenotype. Hence, the greatest differences between CP CML patients and normal donors were apparent in HSC including downregulation of genes encoding adhesion molecules, transcription factors, regulators of stem-cell fate and inhibitors of cell proliferation in CP CML. Impaired adhesive and migratory capacities were functionally corroborated by fibronectin detachment analysis and transwell assays, respectively. Based on our findings we propose a loss of quiescence of the CML HSC on detachment from the niche leading to expansion of myeloid progenitors.

AB TET2 (TET oncogene family member 2) is a candidate tumor suppressor gene located at chromosome 4q24, and was recently reported to be mutated in similar to 14% of patients with JAK2V617F-positive myeloproliferative neoplasms. We used high-throughput DNA sequence analysis to screen for TET2 mutations in bone marrow-derived DNA from 48 patients with systemic mastocytosis (SM), including 42 who met the 2008 WHO (World Health Organization) diagnostic criteria for SM and 6 with FIP1L1-PDGFRA. Twelve (29%) SM, but no FIP1L1-PDGFRA patients, had TET2 mutations. A total of 17 mutations (13 frameshift, 2 nonsense and 2 missense) were documented in 2 (15%) of 13 indolent SM patients, 2 (40%) of 5 aggressive SM, and 8 (35%) of 23 SM associated with a clonal non-mast cell-lineage hematopoietic disease (P = 0.52). KITD816V was detected by PCR sequencing in 50 or 20% of patients with or without TET2 mutation (P = 0.05), respectively. Multivariable analysis showed a significant association between the presence of TET2 mutation and monocytosis (P = 0.0003) or female sex (P = 0.05). The association with monocytosis was also observed in non-indolent SM (n = 29), in which the presence of mutant TET2 did not affect survival (P = 0.98). We conclude that TET2 mutations are frequent in SM, segregate with KITD816V and influence phenotype without necessarily altering prognosis.

AB High-throughput DNA sequence analysis was used to screen for TET2 mutations in bone marrow-derived DNA from 239 patients with BCR-ABL-negative myeloproliferative neoplasms (MPNs). Thirty-two mutations (19 frameshift, 10 nonsense, 3 missense; mostly involving exons 4 and 12) were identified for an overall mutational frequency of similar to 13%. Specific diagnoses included polycythemia vera (PV; n = 89), essential thrombocythemia (ET; n = 57), primary myelofibrosis (PMF; n = 60), post-PV MF (n = 14), post-ET MF (n 7) and blast phase PV/ET/MF (n = 12); the corresponding mutational frequencies were similar to 16, 5, 17, 14, 14 and 17% (P = 0.50). Mutant TET2 was detected in similar to 17 and similar to 7% of JAK2V617F-positive and-negative cases, respectively (P = 0.04). However, this apparent clustering of the two mutations was accounted for by an independent association between mutant TET2 and advanced age; mutational frequency was similar to 23% in patients >= 60 years old versus similar to 4% in younger patients (P<0.0001). The presence of mutant TET2 did not affect survival, leukemic transformation or thrombosis in either PV or PMF; a correlation with hemoglobin <10 g per 100 ml in PMF was noted (P = 0.05). We conclude that TET2 mutations occur in both JAK2V617F-positive and-negative MPN, are more prevalent in older patients, display similar frequencies across MPN subcategories and disease stages, and hold limited prognostic relevance.

AB Cyclin D dysregulation and overexpression is noted in the majority of multiple myeloma (MM) patients, suggesting its critical role in MM pathogenesis. Here, we sought to identify the effects of targeting cyclin D in MM. We first confirmed cyclin D mRNA overexpression in 42 of 64 (65%) patient plasma cells. Silencing cyclin D1 resulted in >50% apoptotic cell death suggesting its validity as a potential therapeutic target. We next evaluated P276-00, a clinical-grade small-molecule cyclin-dependent kinase inhibitor as a way to target the cyclins. P276-00 resulted in dose-dependent cytotoxicity in MM cells. Cell-cycle analysis confirmed either growth arrest or caspase-dependent apoptosis; this was preceded by inhibition of Rb-1 phosphorylation with associated downregulation of a range of cyclins suggesting a regulatory role of P276-00 in cell-cycle progression through broad activity. Proliferative stimuli such as interleukin-6, insulin-like growth factor-1 and bone-marrow stromal cell adherence induced cyclins; P276-00 overcame these growth, survival and drug resistance signals. Because the cyclins are substrates of proteasome degradation, combination studies with bortezomib resulted in synergism. Finally, in vivo efficacy of P276-00 was confirmed in an MM xenograft model. These studies form the basis of an ongoing phase I study in the treatment of relapsed/refractory MM. Leukemia (2009) 23, 961-970; doi:10.1038/leu.2008.378; published online 8 January 2009

AB Low-grade or minimal hepatic encephalopathy (MHE) is characterised by relatively mild neurocognitive impairments, and occurs in a substantial percentage of patients with liver disease. The presence of MHE is associated with a significant compromise of quality of life, is predictive of the onset of overt hepatic encephalopathy and is associated with a poorer prognosis for outcome. Early identification and treatment of MHE can improve quality of life and may prevent the onset of overt encephalopathy, but to date, there has been little agreement regarding the optimum method for detecting MHE. The International Society on Hepatic Encephalopathy and Nitrogen Metabolism convened a group of experts for the purpose of reviewing available data and making recommendations for a standardised approach for neuropsychological assessment of patients with liver disease who are at risk of MHE. Specific recommendations are presented, along with a proposed methodology for further refining these assessment procedures through prospective research.

AB Multiple studies implicate the renin-angiotensin system in hepatic fibrogenesis. Few studies have examined the effects of angiotensin blockade on liver fibrosis via human histology.
We studied the histological effect of angiotensin II blocking agents in chronic hepatitis C patients.
This was a retrospective study of 284 chronic hepatitis C patients from 2001 to 2006 who underwent a liver biopsy. Group I was comprised of 143 hypertensive patients who received angiotensin-blocking agents. Group II was comprised of 91 hypertensive subjects who received hypertensive agents other than angiotensin blockers. Group III was comprised of 50 non-hypertensive subjects.
The groups were similar in age, sex, hepatitis C genotype, viral load and disease duration. They varied significantly in total diabetic patients (Group I, 43; Group II, 10; Group III, 1; P=0.0001), consistent with recommended use of angiotensin-converting enzyme inhibitors in hypertensive diabetics. Non-hypertensive patients had significantly less fibrosis than hypertensive patients, regardless of antihypertensive medications (Group I, 3.20; Group II, 3.73; Group III, 2.5; P=0.0002). Group I had significantly less fibrosis than Group II (P=0.02). This finding persisted in a non-diabetic subgroup of Groups I and II (Group I, 3.07; Group II, 3.69; P=0.0129).
Patients with hepatitis C and hypertension have increased fibrosis compared with non-hypertensive patients. Hypertensive patients receiving angiotensin-blocking agents had less fibrosis than hypertensive patients who did not receive angiotensin-blocking agents. This suggests an association with hypertension, possibly via the renin-angiotensin system in the fibrosis development and suggests a beneficial role of angiotensin II blockade in hepatitis C virus-related fibrosis.

AB Asthma represents a syndrome of airway inflammatory diseases with complex pathology. The immunologic pathogenesis is being increasingly revealed and provides opportunity for targeted biological intervention. Current experience with immunomodulators as targeted therapy in asthma is described in this literature review. Targeted therapies have included strategies to activate dendritic cells through the TLR-9 receptors, to interrupt the action of T(H)2 cytokines with cytokine blockers and monoclonal antibodies, to promote development of TO responses, to block IgE mediated pathways and to block TNF alpha. Omalizumab is the only biological therapy that has an approved indication in asthma at this time. An improved understanding of the heterogeneity of asthma should allow for specific targeting of different disease phenotypes specific therapies including immunomodulators.

AB Purpose: To develop a post-processing, respiratory-motion correction algorithm for magnetic resonance spectroscopy (MRS) of the liver and to determine the incidence and impact of respiratory motion in liver MRS.
Materials and Methods: One hundred thirty-two subjects (27 healthy, 31 with nonalcoholic fatty liver disease and 74 HIV-infected with or without hepatitis C) were scanned with free breathing MRS at 1.5 T. Two spectral time series were acquired on an 8-ml single voxel using TR/TE=2500 ms/30 ms and (1) water suppression, 128 acquisitions, and (2) no water suppression, 8 acquisitions. Individual spectra were phased and frequency aligned to correct for intrallepatic motion. Next, water peaks more than 50% different from the median water peak area were identified and removed, and remaining spectra averaged to correct for presumed extrallepatic motion. Total CH(2)+CH(3) lipids to unsuppressed water ratios were compared before and after corrections.
Results: Intrahepatic-motion correction increased the signal to noise ratio (S/N) in all cases (median=11-fold). Presumed extrahepatic motion was present in 41% (54/132) of the subjects. Its correction altered the lipids/water magnitude (magnitude change: median=2.6%, maximum=290%, and was >5% in 25% of these subjects). The incidence and effect of respiratory motion on lipids/water magnitude were similar among the three groups.
Conclusion: Respiratory-motion correction of free breathing liver MRS greatly increased the S/N and, in a significant number of subjects, changed the lipids/water ratios, relevant for monitoring subjects. (C) 2009 Elsevier Inc. All rights reserved.

AB Genetic variation is known to influence the amount of mRNA produced by a gene. Because molecular machines control mRNA levels of multiple genes, we expect genetic variation in components of these machines would influence multiple genes in a similar fashion. We show that this assumption is correct by using correlation of mRNA levels measured from multiple tissues in mouse strain panels to detect shared genetic influences. These correlating groups of genes (CGGs) have collective properties that on average account for 52-79% of the variability of their constituent genes and can contain genes that encode functionally related proteins. We show that the genetic influences are essentially tissue-specific and, consequently, the same genetic variations in one animal may upregulate a CGG in one tissue but downregulate the CGG in a second tissue. We further show similarly paradoxical behaviour of CGGs within the same tissues of different individuals. Thus, this class of genetic variation can result in complex inter- and intraindividual differences. This will create substantial challenges in humans, where multiple tissues are not readily available.

AB Blood vessel formation in the vertebrate eye is a precisely regulated process. in the human retina, both an excess and a deficiency of blood vessels may lead to a loss of vision. To gain insight into the molecular basis of vessel formation in the vertebrate retina and to develop pharmacological means of manipulating this process in a living organism, we further characterized the embryonic zebrafish eye vasculature, and performed a small molecule screen for compounds that affect blood vessel morphogenesis. The screening of approximately 2000 compounds revealed four small molecules that at specific concentrations affect retinal vessel morphology but do not produce obvious changes in trunk vessels, or in the neuronal architecture of the retina. Of these, two induce a pronounced widening of vessel diameter without a substantial loss of vessel number, one compound produces a loss of retinal blood vessels accompanied by a mild increase of their diameter, and finally one other generates a severe loss of retinal vessels.

AB Background: There is little national data oil the characteristics of patients who receive high quality inpatient care defined as either the receipt of all appliable processes (all-or-none performance) or the proportion of applicable processes received during thier hospitalization.
Objectives: To assess the quality of care provided to patients hospitalized for acute myocardial infarction (AMI), heart failure or pneumonia, to describe variations in quality by patient and hospital characteristics, and the sensitivity of all-or-none performance to the number and type of processes.
Design and Subjects: Retrospective analysis of previously unavailable Hospital Quality Alliance patient-level data on 2.3 million individuals receiving care in non-federal US hospitals in 2005.
Measures: The proportion of patients who received all applicable care processes, and the mean proportion of applicable processes received by hospitalized patients.

AB In this study, the authors investigated the feasibility of using a 3D liquid scintillator (LS) detector system for the verification and characterization of proton beams in real time for intensity and energy-modulated proton therapy. A plastic tank filled with liquid scintillator was irradiated with pristine proton Bragg peaks. Scintillation light produced during the irradiation was measured with a CCD camera. Acquisition rates of 20 and 10 frames per second (fps) were used to image consecutive frame sequences. These measurements were then compared to ion chamber measurements and Monte Carlo simulations. The light distribution measured from the images acquired at rates of 20 and 10 fps have standard deviations of 1.1% and 0.7%, respectively, in the plateau region of the Bragg curve. Differences were seen between the raw LS signal and the ion chamber due to the quenching effects of the LS and due to the optical properties of the imaging system. The authors showed that this effect can be accounted for and corrected by Monte Carlo simulations. The liquid scintillator detector system has a good potential for performing fast proton beam verification and characterization.

AB Laxative-free computed tomographic colonography (lfCTC) could significantly improve patient adherence to colorectal screening. However, the interpretation of lfCTC data is complicated by the presence of poorly tagged feces and partial-volume artifacts that imitate colorectal lesions. The authors developed a method for virtual tagging of such artifacts. A probabilistic model of colonic wall was developed, and virtual tagging was performed on artifacts that were identified by the model. The method was evaluated with 46 clinical lfCTC cases that were prepared with dietary fecal tagging only. Visual examples show that the method can label partial-volume artifacts, poorly tagged feces, nonadhering completely untagged feces, and artifacts such as rectal tubes. The effect of virtual tagging was evaluated by comparing the detection accuracy of a fully automated polyp detection scheme without and with the method. With virtual tagging, the per-lesion detection sensitivity was 100% for lesions >= 10 mm (n=4) with 3.8 false positives per patient (per two CT scan volumes) and 90% for lesions >= 6 mm (n=10) with 5.4 false positives per patient on average. The improvement in detection performance by virtual tagging was statistically significant (p=0.03; JAFROC and JAFROC-1).

AB A mini-multileaf collimator (MMLC) was mounted as a field shaping collimator in a proton beamline at the Massachusetts General Hospital. The purpose is to evaluate the device's dosimetric and mechanical properties for the use in a proton beamline. For this evaluation, the authors compared MMLC and brass aperture shaped dose distributions with regard to lateral and depth dose properties. The lateral fall off is generally broader with the MMLC, with difference varying with proton range from 0.2 to 1.2 mm. Central axis depth dose curves did not show a difference in peak-to-entrance ratio, peak width, distal fall off, or range. Two-dimensional dose distributions to investigate the conformity of MMLC shaped doses show that the physical leaf width of approximate to 2.5 mm does not have a significant impact. All differences seen in dose distribution shaped by the MMLC versus brass apertures were shown to be clinically insignificant. Measured neutron doses of 0.03-0.13 mSv/Gy for a closed brass beam block (depending on range) are very low compared to the previously published data. Irradiation of the tungsten MMLC, however, produced 1.5-1.8 times more neutrons than brass apertures. Exposure of the staff resulting from activation of the device is below regulatory limits. The measurements established an equivalency between aperture and MMLC shaped dose distributions.

AB Background: Ultrasound measurement of the optic nerve sheath diameter (ONSD) had been shown to correlate with intracranial pressure (ICP). This study looked at intra-observer and inter-observer reliability among three emergency physicians (EPs) using three different imaging protocols.
Material/Methods: Ocular ultrasound was performed in 20 healthy volunteers. Each physician obtained 3 measurements of the right eye ONSD with both the 10-5 MHz and 13-6 MHz probes using the axial imaging technique (experiment 1). The ONSD was then measured with the 10-5 MHz probe using the axial technique and the intracavitary 8-5 MHz probe using the coronal technique (experiment 2).
Results: In experiment 1, larger measurements were obtained with the standard 10-5 MHz probe with an adjusted difference of 0.21 mm (p<0.001). The standard deviation between intra-observer measurements for the 10-5 MHz probe was slightly but not significantly larger with an adjusted difference of 0.039 (p=0.10). In experiment 2, larger measurements were obtained with the standard 10-5 MHz probe with an adjusted difference of 0.91 mm (p<0.001). The standard deviation between intra-observer measurements was greater for the 10-5 MHz probe with an adjusted difference of 0.06 (p=0.03). The inter-observer measurements in experiment 2 had significantly larger variance with the 10-5 MHz probe (p=0.001).
Conclusions: These data suggest comparable precision and inter-observer reliability can be achieved. However, larger values when using the 10-5 MHz probe suggest different cut-off thresholds for normal upper limits. The coronal imaging technique demonstrated less inter-rater variance and may be a better technique when such small measurement differences are important.

Cardiac Dysfunction during Exercise in Uncomplicated Type 2 Diabetes. Med. Sci. Sports Exerc., Vol. 41, No. 5, pp. 977-984, 2009. Purpose: Type 2 diabetes mellitus (T2DM) has been associated with reduced peak exercise capacity ((V) over dotO(2peak)). The causes of this impairment are not clearly established, but evidence Suggests that abnormalities in cardiac function play a significant role. We hypothesized that exercise would be associated with impaired cardiac function and hemodynamics in recently diagnosed T2DM, even in the absence of clinically evident cardiovascular complications. Methods: After baseline normal echocardiography screening, 10 premenopausal women with uncomplicated T2DM (average duration of diagnosed T2DM, 3.6 yr) and 10 healthy nondiabetic women of similar age, weight, and activity levels performed a peak cardiopulmonary exercise test while instrumented with all indwelling pulmonary artery catheter for assessing cardiac function. On separate days, technetium-99 sestamibi (cardolite) imaging was performed to assess myocardial perfusion at rest and peak exercise in seven T2DM and seven control patients. Results: Resting measures of cardiac hemodynamics were similar in T2DM and control Subjects. Absolute (V) over dotO(2peak) (mL.min(-1)) and peak cardiac output tended to be lower in T2DM than in control subjects but did not reach statistical significance. However, pulmonary capillary wedge pressure (PCWP) rose significantly more during exercise in T2DM than in controls (148% vs 109% increase at peak exercise, P<0.01). Normalized myocardial perfusion index was lower in persons with diabetes than in controls(11.0 +/- 3.5 x e(-9) vs 17.5 +/- 8.1 x e(-9), respectively, P < 0.05) and inversely related to peak exercise PCWP (R = -0.56, P < 0.05). Conclusions: Cardiac hemodynamics during graded exercise are altered in women with recently diagnosed T2DM as demonstrated by the disproportionate increase in PCWP at peak exercise compared with controls subjects. Cardiac abnormalities observed are potentially early signs of subclinical cardiac dysfunction associated with T2DM, which may precede the more greatly impaired cardiac function at rest and with exercise observed in longer established T2DM.

Purpose: To describe and compare the prevalence of physical activity (PA) in relation to veteran status and use of Department of Veterans Affairs (VA) facilities. Methods: Data were obtained from the 2003 Behavioral Risk Factor Surveillance System surveys of US adults. Veteran status, VA health care use, and PA were determined in 245,564 adults. Individuals were classified as inactive, insufficiently active, or meeting recommendations for moderate or strenuous PA. To adjust for confounding, we used model-based direct adjustment and chi-square tests corrected for the survey design. Results: After adjusting for age and gender, the prevalence of inactivity was significantly lower (16.2% vs 20.5%), and meeting PA recommendations was significantly greater (46.0% vs 42.0%) in veterans than in nonveterans (P < 0.0001). Compared with veterans who did not obtain their health care from the VA, VA users were more likely to be inactive (20.8% vs 14.7%) and less likely to be insufficiently active (34.1% vs 38.2%) or meet recommendations (45.1% vs 47.1%; P < 0.0001). Differences in PA levels between veterans and nonveterans and between VA users and nonusers did not change substantially after additional adjustment for education, race/ethnicity, and smoking. Conclusion: Despite the high level of PA required of active duty military personnel, only a minority of veterans met PA recommendations, and the prevalence of inactivity was particularly high in VA users. These findings suggest a large potential to increase PA and improve health in VA users.

AB The purpose of this study was to evaluate the relationship of respiratory quotient (RQ), a surrogate marker of substrate oxidation, as well as body composition and dietary intake to resting energy expenditure (REE) among HIV-infected patients in the current era of highly active antiretroviral therapy and among non-HIV-infected control subjects. Resting energy expenditure is increased in HIV-infected patients; but little is known regarding the potential contribution of altered substrate metabolism, body composition, and dietary intake to increased energy expenditure in this Population. Respiratory quotient, REE, body composition, and dietary intake parameters were assessed in 283 HIV-infected patients and 146 community-derived HIV-negative controls who were evaluated for metabolic Studies between 1998 and 2005. Respiratory quotient was lower (0.83 +/- 0.00 vs 0.85 +/- 0.01, P = .005), whereas REE adjusted for fat-free mass (FFM) was higher (31.8 +/- 0.3 vs 29.8 +/- 0.3 kcal/[d kg], P <= .0001), in HIV-infected compared with control subjects. In multivariate modeling among HIV-infected patients, including age, sex, and parameters of immune function, FFM (beta = 24.811334, P < .0001), visceral adiposity (beta = .7182746, P = .008), and total body fat (beta = 8.0506839, P = .041) were positively associated with REE. whereas RQ was negatively associated with REE (beta = -528.4808, P = .024). Overall r(2) was equal to 0.705 and P was less than .0001 for the model. In control subjects, by contrast, only visceral adiposity (beta = 1.0612073, P = .004), total body fat (beta = 15.805547, P = .010), and FFM (beta = 22.613005, P < .0001) were significant predictors of REE and there was no relationship with RQ. Overall r(2) was equal to 0.825 and P was less than .0001 for the model. These data suggest that alterations in substrate metabolism may contribute to increased REE in HIV-infected patients compared with control subjects. (C) 2009 Elsevier Inc. All rights reserved.

AB The material properties of bone are the sum of the complex and interrelated anabolic and catabolic processes that modulate formation and turnover. The 2q33-37 region of the human genome contains quantitative trait loci important in determining the broadband ultrasound attenuation (an index of trabecular microarchitecture, bone elasticity, and susceptibility to fracture) of the calcaneus, but no genes of significance to boric metabolism have been identified in this domain. Secreted phosphoprotein-24 kd (SPP24 or SPP2) is a novel and relatively poorly characterized growth hormone-regulated gene that maps to 2q37. The purpose of this review is to summarize the status of research related to spp24 and how it regulates bone morphogenetic protein (BMP) bioactivity in bone. SPP24 codes for an extracellular matrix protein that contains a high-affinity BMP-2-binding transforming growth factor-beta receptor 11 homology I loop similar to those identified in fetuin and the receptor itself. SPP24 is transcribed primarily in the liver and bone. High levels of spp24 (a hydroxyapatite-binding protein) arc found in bone, and small amounts are found in fetuin-mineral complexes. Full-length secretory spp24 inhibits ectopic bone formation, and overexpression of spp24 reduces murine bone mass and density. Spp24 is extremely labile to proteolysis, a process that regulates its bioactivity in vivo. For example, an 18.5-kd degradation product of spp24, designated spp 18,5, is pro-osteogenic. A synthetic cyclized Cys(1)-to-Cys(19) disulfide-bonded peptide (BMP binding peptide) corresponding to the transforming growth factor-beta receptor 11 homology 1 domain of spp24 and spp 18.5 binds BMP-2 and increases the rate and magnitude of BMP-2-mediated ectopic bone formation. Thus, the mechanism of action of spp 18.5 and spp24 may be to regulate the local bioavailability of BNIP cytokines. SPP24 is regulated by growth hormone and 3 major families of transcription factors (nuclear factor of activated T cells, CCAAT/enhancer-binding protein, Cut/Cux/CCAAT displacement protein) that regulate mesenchymal cell proliferation, embryonic patterning, and terminal differentiation. The gene contains at least 2 single nucleotide polymorphisms. Given its mechanism of action and sequence variability, SPP24 may be an interesting candidate for future studies of the genetic regulation of bone mass, particularly during periods of BMP-mediated endochondral bone growth, development, and fracture healing.

AB Although previous studies have demonstrated that microvascular dysfunction and inflammation occur in ischemia-reperfusion injury (IRI), the underlying mechanisms are poorly understood. We hypothesized that T cells could mediate renal vascular permeability (RVP) during IRI. We evaluated renal vascular permeability by extravasation of Evans blue dye from the kidney in CD3, CD4 or CD8 T cell deficient mice as well as in TNF receptor knock out mice in our mouse model of kidney ischemia-reperfusion injury. In wild type mice, RVP was significantly increased at 3 h, peaked at 6 h and declined by 24 h after ischemia. Immunohistochemistry revealed that CD3(+) T cells trafficked into ischemic kidney at 1 h and peaked at 6 h. Gene microarray analysis demonstrated that endothelial-related genes including TNF-alpha were upregulated in ischemic kidney. The production of TNF-alpha and IFN-gamma protein was increased in CD3 and CD4 T cells from the blood and kidney after ischemia. The rise in RVP after ischemia in wild type mice was attenuated in CD3, CD4 or CD8 T cell deficient mice as well as in TNF receptor knock out mice. The attenuation of RVP in CD3 T-cell deficient mice after ischemia was restored by adoptive transfer of T cells from WT mice. Our data demonstrate that T cells directly contribute to the increased RVP after kidney ischemia-reperfusion, potentially through T cell cytokine production. (C) 2009 Elsevier Inc.

AB Recurrent nevus phenomenon and regression in melanoma may have overlapping histologic features. The clinical findings and histologic changes in 357 cases of recurrent nevus phenomenon were compared with 34 cases of melanoma with regression. Regression was defined as (1) Early: dense lymphoid infiltrates replacing nests of melanocytes, (2) Intermediate: absence/loss of tumor with replacement by mix of lymphocytes and melanophages and early fibrosis, and (3) Late: tumor absence with extensive fibrosis and telangiectasia, melanophages and epidermal effacement. Four broad histologic patterns of recurrent nevus were identified and classified into type 1: junctional melanocytic hyperplasia with effacement of the retiform epidermis and associated dermal scar, type 2: compound melanocytic proliferation with effacement of the retiform epidermis and associated dermal scar, type 3: junctional melanocytic hyperplasia with retention of the retiform epidermis, and type 4: compound melanocytic hyperplasia with retention of the retiform epidermis and scar. Melanomas with early and intermediate regression were recognizable due to the presence of residual melanoma. Melanomas with late regression had overlapping features of type 1 and 2 recurrent nevi. Type 3 recurrent nevi resembled primary melanoma with scar/fibrosis. Histologically, the vast majority of recurrent nevi are readily identifiable; however, partial biopsies or cases without prior knowledge of the original biopsy may lead to misdiagnosis. This is especially true in recurrent nevus and regression in malignant melanoma, where these two lesions share overlapping histologic features. Correlation with the clinical findings and prior biopsy will avoid these pitfalls. Modern Pathology (2009) 22, 611-617; doi: 10.1038/modpathol.2009.22; published online 6 March 2009

AB Human herpesvirus type 8 (HHV8), also known as Kaposi's sarcoma-associated herpesvirus, is a human c herpesvirus that underlies the pathogenesis of Kaposi's sarcoma, primary effusion lymphoma and multicentric Castleman's disease. We recently encountered two cases of HHV8-positive large B-cell lymphoma with features not previously described. The first patient was a 61-year-old immunocompetent man with an enlarged cervical lymph node containing scattered large, bizarre cells in a reactive background of lymphocytes, plasma cells and scattered regressed follicles resembling those of hyaline-vascular Castleman's disease. The appearance suggested classical Hodgkin's lymphoma, but the large cells were negative for CD15, CD30, CD20 and CD3, and positive for MUM1/IRF4, EMA, HHV8, EBER and dim IgM lambda. The second patient was a 59-year-old HIV-positive man who died after several weeks of fever, night sweats, anemia, thrombocytopenia, hepatosplenomegaly and multiorgan failure. At autopsy an intravascular large B-cell lymphoma that was positive for MUM1/IRF4, HHV8 and IgM lambda, and negative for CD20 and EBER involved multiple organs, including lung, heart, kidney, liver and spleen. On the basis of the histologic features in these two cases, the presence of HHV8 was unexpected. These cases expand the spectrum of lymphoproliferative disorders that can be associated with HHV8.

AB sTranscription factor LSF is required for progression from quiescence through the cell cycle, regulating thymidylate synthase (Tyms) expression at the G(1)/S boundary. Given the constant level of LSF protein from G(0) through S, we investigated whether LSF is regulated by phosphorylation in G(1). In vitro, LSF is phosphorylated by cyclin E/cyclin-dependent kinase 2 (CDK2), cyclin C/CDK2, and cyclin C/CDK3, predominantly on S309. Phosphorylation of LSF on S309 is maximal 1 to 2 h after mitogenic stimulation of quiescent mouse fibroblasts. This phosphorylation is mediated by cyclin C-dependent kinases, as shown by coimmunoprecipitation of LSF and cyclin C in early G(1) and by abrogation of LSF S309 phosphorylation upon suppression of cyclin C with short interfering RNA. Although mouse fibroblasts lack functional CDK3 (the partner of cyclin C in early G(1) in human cells), CDK2 compensates for this absence. By transient transfection assays, phosphorylation at S309, mediated by cyclin C overexpression, inhibits LSF transactivation. Moreover, overexpression of cyclin C and CDK3 inhibits induction of endogenous Tyms expression at the G(1)/S transition. These results identify LSF as only the second known target (in addition to pRb) of cyclin C/CDK activity during progression from quiescence to early G(1). Unexpectedly, this phosphorylation prevents induction of LSF target genes until late G(1).

CONSTITUTIVE ACTIVITY
AB Many biochemical pathways are driven by G protein-coupled receptors, cell surface proteins that convert the binding of extracellular chemical, sensory, and mechanical stimuli into cellular signals. Their interaction with various ligands triggers receptor activation that typically couples to and activates heterotrimeric G proteins, which in turn control the propagation of secondary messenger molecules (e. g. cAMP) involved in critically important physiological processes (e. g. heart beat). Successful transfer of information from ligand binding events to intracellular signaling cascades involves a dynamic interplay between ligands, receptors, and G proteins. The development of Forster resonance energy transfer and bioluminescence resonance energy transfer-based methods has now permitted the kinetic analysis of initial steps involved in G protein-coupled receptor-mediated signaling in live cells and in systems as diverse as neurotransmitter and hormone signaling. The direct measurement of ligand efficacy at the level of the receptor by Forster resonance energy transfer is also now possible and allows intrinsic efficacies of clinical drugs to be linked with the effect of receptor polymorphisms.

AB Inhibiting the proteolytic activity of the 26S proteasome has been shown to have selective apoptotic effects on cancer cells and to be clinically efficacious in certain malignancies. There is an unmet medical need for additional proteasome inhibitors, and their development will be facilitated by surrogate markers of proteasome function. Toward this end, ectopic fusion of the destruction domain from ornithine decarboxylase (ODC) to reporter proteins is often used for assessing proteasome function. For luciferase-based reporters, we hypothesized that the oxygen-dependent destruction domain (ODD) from hypoxia-inducible factor 1 alpha (HIF-1 alpha) may provide improved sensitivity over luciferase-ODC, owing to its extremely rapid turnover by the proteasome (HIF-1a has a half-life of less than 5 minutes). In the current study, we show that ODD-luciferase affords a greater dynamic range and faster kinetics than luciferase-ODC in sensing proteasome inhibition in vitro. Importantly, ODD-luciferase also serves as an effective in vivo marker of proteasome function in xenograft tumor models, with inhibition being detected by noninvasive imaging within 3 hours of bortezomib administration. These data establish ODD-luciferase as a surrogate marker of proteasome function that can be used both in vitro and in vivo for the development of novel proteasome inhibitors.

AB Azietomidate is a photoreactive analog of the general anesthetic etomidate that acts as a nicotinic acetylcholine receptor (nAChR) noncompetitive antagonist. We used rapid perfusion electrophysiological techniques to characterize the state dependence and kinetics of azietomidate inhibition of Torpedo californica nAChRs and time-resolved photolabeling to identify the nAChR binding sites occupied after exposure to [(3)H]azietomidate and agonist for 50 ms (open state) or at equilibrium (desensitized state). Azietomidate acted primarily as an open channel inhibitor characterized by a bimolecular association rate constant of k(+) = 5 x 10(5) M(-1) s(-1) and a dissociation rate constant of <3 s(-1). Azietomidate at 10 mu M, when perfused with acetylcholine (ACh), inhibited the ACh response by similar to 50% after 50 ms; when preincubated for 10 s, it decreased the peak initial response by similar to 15%. Comparison of the kinetics of recovery of ACh responses after exposure to ACh and azietomidate or to ACh alone indicated that at subsecond times, azietomidate inhibited nAChRs without enhancing the kinetics of agonist-induced desensitization. In nAChRs frozen after 50-ms exposure to agonist and [(3)H] azietomidate, amino acids were photolabeled in the ion channel [position M2-20 (alpha Glu-262, beta Asp-268, delta Gln-276)], in delta M1 (delta Cys-236), and in alpha MA/alpha M4 (alpha Glu-390, alpha Cys-412) that were also photolabeled in nAChRs in the equilibrium desensitized state at approximately half the efficiency. These results identify azietomidate binding sites at the extracellular end of the ion channel, in the delta subunit helix bundle, and in the nAChR cytoplasmic domain that seem similar in structure and accessibility in the open and desensitized states of the nAChR.

AB Viral vectors have been used to deliver a wide range of therapeutic genes to tumors. In this study, a novel tumor therapy was achieved by the delivery of a mammalian brain sodium channel, ASIC2a, carrying a mutation that renders it constitutively open. This channel was delivered to tumor cells using a herpes simplex virus-1/Epstein-Barr virus (HSV/EBV) hybrid amplicon vector in which gene expression was controlled by a tetracycline regulatory system (tet-on) with silencer elements. Upon infection and doxycycline induction of mutant channel expression in tumor cells, the open channel led to amiloride-sensitive sodium influx as assessed by patch clamp recording and sodium imaging in culture. Within hours, tumor cells swelled and died. In addition to cells expressing the mutant channel, adjacent, noninfected cells connected by gap junctions also died. Intratumoral injection of HSV/EBV amplicon vector encoding the mutant sodium channel and systemic administration of doxycycline led to regression of subcutaneous tumors in nude mice as assessed by in vivo bioluminescence imaging. The advantage of this direct mode of tumor therapy is that all types of tumor cells become susceptible and death is rapid with no time for the tumor cells to become resistant.

AB Somatically acquired epigenetic changes are present in many cancers. Epigenetic regulation is maintained via post-translational modifications of core histones. Here, we describe inactivating somatic mutations in the histone lysine demethylase gene UTX, pointing to histone H3 lysine methylation deregulation in multiple tumor types. UTX reintroduction into cancer cells with inactivating UTX mutations resulted in slowing of proliferation and marked transcriptional changes. These data identify UTX as a new human cancer gene.

TI Braf(V600E) cooperates with Pten loss to induce metastatic melanoma

MELANOCYTES; SENESCENCE; MOUSE; MICE; INHIBITOR; GENETICS
AB Mutational activation of BRAF is the earliest and most common genetic alteration in human melanoma. To build a model of human melanoma, we generated mice with conditional melanocyte-specific expression of BRaf(V600E). Upon induction of BRaf(V600E) expression, mice developed benign melanocytic hyperplasias that failed to progress to melanoma over 15-20 months. By contrast, expression of BRaf(V600E) combined with Pten tumor suppressor gene silencing elicited development of melanoma with 100% penetrance, short latency and with metastases observed in lymph nodes and lungs. Melanoma was prevented by inhibitors of mTorc1 (rapamycin) or MEK1/2 (PD325901) but, upon cessation of drug administration, mice developed melanoma, indicating the presence of long-lived melanoma-initiating cells in this system. Notably, combined treatment with rapamycin and PD325901 led to shrinkage of established melanomas. These mice, engineered with a common genetic profile to human melanoma, provide a system to study melanoma's cardinal feature of metastasis and for preclinical evaluation of agents designed to prevent or treat metastatic disease.

AB Using deep sequencing (deepCAGE), the FANTOM4 study measured the genome-wide dynamics of transcription-start-site usage in the human monocytic cell line THP-1 throughout a time course of growth arrest and differentiation. Modeling the expression dynamics in terms of predicted cis-regulatory sites, we identified the key transcription regulators, their time-dependent activities and target genes. Systematic siRNA knockdown of 52 transcription factors confirmed the roles of individual factors in the regulatory network. Our results indicate that cellular states are constrained by complex networks involving both positive and negative regulatory interactions among substantial numbers of transcription factors and that no single transcription factor is both necessary and sufficient to drive the differentiation process.

AB Foxo transcription factors regulate cell cycle progression, cell survival and DNA-repair pathways. Here we demonstrate that deficiency in Foxo3 resulted in greater expansion of T cell populations after viral infection. This exaggerated expansion was not T cell intrinsic. Instead, it was caused by the enhanced capacity of Foxo3-deficient dendritic cells to sustain T cell viability by producing more interleukin 6. Stimulation of dendritic cells mediated by the coinhibitory molecule CTLA-4 induced nuclear localization of Foxo3, which in turn inhibited the production of interleukin 6 and tumor necrosis factor. Thus, Foxo3 acts to constrain the production of key inflammatory cytokines by dendritic cells and to control T cell survival.

TI miR-24-mediated downregulation of H2AX suppresses DNA repair in
terminally differentiated blood cells
SO NATURE STRUCTURAL & MOLECULAR BIOLOGY
LA English
DT Article
ID EXPRESSION; MICRORNAS; PROLIFERATION; PROTEIN; RNA
AB Terminally differentiated cells have a reduced capacity to repair double-stranded breaks, but the molecular mechanism behind this downregulation is unclear. Here we find that miR-24 is upregulated during postmitotic differentiation of hematopoietic cell lines and regulates the histone variant H2AX, a protein that has a key role in the double-stranded break response. We show that the H2AX 3' untranslated region contains conserved miR-24 binding sites that are indeed regulated by miR-24. During terminal differentiation, both H2AX mRNA and protein levels are substantially reduced by miR-24 upregulation in in vitro differentiated cells; similar diminished levels are found in primary human blood cells. miR-24-mediated suppression of H2AX renders cells hypersensitive to gamma-irradiation and genotoxic drugs, a phenotype that is fully rescued by overexpression of miR-24-insensitive H2AX. Therefore, miR-24 upregulation in postreplicative cells reduces H2AX and makes them vulnerable to DNA damage.

AB Nitric oxide (NO) activates soluble guanylate cyclase (sGC) to produce guanosine-3',5'-cyclic-monophosphate (cGMP). The aim of this study was to investigate the nitrergic regulation of jejunal motility in sGC alpha(1) knockout (KO) mice. Functional responses to nitrergic stimuli and cGMP levels in response to nitrergic stimuli were determined in circular muscle strips. Intestinal transit was determined. Nitrergic relaxations induced by electrical field stimulation and exogenous NO were almost abolished in male KO strips, but only minimally reduced and sensitive to ODQ in female KO strips. Basal cGMP levels were decreased in KO strips, but NO still induced an increase in cGMP levels. Transit was not attenuated in male nor female KO mice. In vitro, sGC alpha(1)beta(1) is the most important isoform in nitrergic relaxation of jejunum, but nitrergic relaxation can also occur via sGC alpha(2)beta(1) activation. The latter mechanism is more pronounced in female than in male KO mice. In vivo, no important implications on intestinal motility were observed in male and female KO mice.

AB AURKA (the official symbol for Aurora-A, STK15, or BTAK) regulates the function of centrosomes, spindles, and kinetochores for proper mitotic progression. AURKA overexpression is observed in various cancers including colon cancer, and a link between AURKA and chromosomal instability (CIN) has been proposed. However, no study has comprehensively examined AURKA expression in relation to CIN or prognosis using a large number of tumors. Using 517 colorectal cancers in two prospective cohort studies, we detected AURKA overexpression (by immunohistochemistry) in 98 tumors (19%). We assessed other molecular events including loss of heterozygosity (LOH) in 2p, 5q, 17q, and 18q, the CpG island methylation phenotype (CIMP), and microsatellite instability (MSI). Prognostic significance of AURKA was evaluated by Cox regression and Kaplan-Meier method. In both univariate and multivariate logistic regressions, AURKA overexpression was significantly associated with CIN (defined as the presence of LOH in any of the chromosomal segments; multivariate odds ratio, 2.97; 95% confidence interval, 1.40-6.29; P = .0045). In multivariate analysis, AURKA was associated with cyclin D1 expression (P= .010) and inversely with PIK3CA mutation (P= .014), fatty acid synthase expression (P= .028), and family history of colorectal cancer (P = .050), but not with sex, age, body mass index, tumor location, stage, CIMP, MSI, KRAS, BRAF, BMI, LINE-1 hypomethylation, p53, p21, beta-catenin, or cyclooxygenase 2. AURKA was not significantly associated with clinical outcome or survival. In conclusion, AURKA overexpression is independently associated with CIN in colorectal cancer, supporting a potential role of Aurora kinase-A in colorectal carcinogenesis through genomic instability (rather than epigenomic instability).

AB Doxycycline, a tetracycline antibiotic inhibits matrix metalloproteinase (MMP) and reduces neuronal damage in local brain ischemia. This study was undertaken to assess if doxycycline reduces delayed neuronal damage following transient global cerebral ischemia through MMIP inhibition. C57BL/6 mice were subjected to 20 min global cerebral ischemia. Doxycycline was administered to mice 30 min before and 2 h after ischemia. In TUNEL assay, damaged neurons were also apparent in the CA1 and CA2 areas and doxycycline reduced TUNEL-positive neurons. Gelatin gel and in situ zymography showed upregulation of gelatinase activity after ischemia. Doxycycline significantly inhibited MMP-9 activity in gel zymography and also suppressed in situ gelatinase activity. Laminin degradation was remarkable in CA1 and CA2 areas after ischemia and doxycycline reduced the laminin degradation and neuronal loss. Our data suggest that doxycycline may provide a neuroprotection against global cerebral ischemia since it reduces perineuronal laminin degradation by inhibiting MMP-9 activity. (C) 2008 Elsevier Inc.

AB In mostly small single-center studies, Alzheimer's disease (AD) is associated with characteristic and progressive reductions in fluorodeoxyglucose positron emission tomography (PET) measurements of the regional cerebral metabolic rate for glucose (CMRgl). The AD Neuroimaging Initiative (ADNI) is acquiring FDG PET, volumetric magnetic resonance imaging, and other biomarker measurements in a large longitudinal multi-center study of initially mildly affected probable AD (pAD) patients, amnestic mild cognitive impairment (aMCI) patients, who are at increased AD risk, and cognitively normal controls (NC), and we are responsible for analyzing the PET images using statistical parametric mapping (SPM). Here we compare baseline CMRgl measurements from 74 pAD patients and 142 aMCI patients to those from 82 NC, we correlate CMRgl with categorical and continuous measures of clinical disease severity, and we compare apolipoprotein E (APOE) epsilon 4 carriers to non-carriers in each of these subject groups. In comparison with NC, the pAD and aMCI groups each had significantly lower CMRgl bilaterally in posterior cingulate, precuneus, parietotemporal and frontal cortex. Similar reductions were observed when categories of disease severity or lower Mini-Mental State Exam (MMSE) scores were correlated with lower CMRgl. However, when analyses were restricted to the pAD patients, lower MMSE scores were significantly correlated with lower left frontal and temporal CMRgl. These findings from a large, multi-site study support previous single-site findings, supports the characteristic pattern of baseline CMRgl reductions in AD and aMCI patients, as well as preferential anterior CMRgl reductions after the onset of AD dementia.

AB Understanding cerebrovascular responses to hyperoxia and hypercapnia is important for investigating exogenous regulation of cerebral hemodynamics. We characterized gas-induced vascular changes in the brains of anesthetized healthy rats using magnetic resonance imaging (MRI) while the rats inhaled 100% O(2) (hyperoxia) and 5% CO(2) (hypercapnia). We used echo planar imaging (EPI), arterial spin labeling (ASL), and intravascular superparamagnetic iron oxide nanoparticles (SPION) to quantify vascular responses as measured by blood oxygenation level dependence (BOLD), cerebral blood flow (CBF), cerebral blood volume (CBV), microvascular volume (MVV), and vessel size index (VSI) in multiple brain regions. Hyperoxia resulted in a statistically significant increase in BOLD-weighted MRI signal and significant decrease in CBF and CBV (P < 0.05). During hypercapnia, we observed significant increases in BOLD signal, CBF, MVV, and CBV (P < 0.05). Despite the regional variability, general trends of vasoconstriction and vasodilation were reflected in VSI changes during O(2) and CO(2) challenges. Interestingly, there was an evident spatial disparity between the O(2) and CO(2) stimuli-induced functional activation maps; that is, cortical and subcortical regions of the brain exhibited notable differences in response to the two gases. Hemodynamic parameters measured in the cortical regions showed greater reactivity to CO(2), whereas these same parameters measured in subcortical regions showed greater responsivity to O(2). Our results demonstrate significant changes of hemodynamic MRI parameters during systemic hypercapnia and hyperoxia in normal cerebral tissue. These gas-dependent changes are spatiotemporally distinctive, suggesting important feasibility for exogenously controlling local cerebral perfusion. (C) 2008 Elsevier Inc. All rights reserved.

AB We report a general method of Bayesian estimation that uses prior measurements to improve the signal-to-noise ratio of parametric images computed from dynamic PET scanning. In our method, the ordinary weighted least squares cost function is augmented by a penalty term to yield F K; S min(K){(C-f(K))(T) Omega(-1)(C)(C-f(K)) + S Phi(K, S = 0)(K-(K) over cap)(T)W(K)(-1)(K-(K) over cap) , where C is a PET concentration history and Omega(C) is its variance, f is the model of the concentration history, K = [k(1), k(2),..., k(m)](T) is the parameter vector, (K) over cap is the vector of population means for the model parameters, Omega(K) is its covariance, Phi(K)(K, S = 0) is the conventional weighted sum of squares. S > 0 is chosen to control the balance between the prior and new data. Data from a prior population of subjects are analyzed with standard methods to provide maps of the mean parameter values and their variances. As an example of this approach we used the dynamic image data of 10 normal subjects who had previously been studied with (11)C-raclopride to estimate the prior distribution. The dynamic data were transformed to stereotactic coordinates and analyzed by standard methods. The resulting parametric maps were used to compute the voxel-wise sample statistics. Then the cohort of priors was analyzed as a function of S, using nonlinear least squares estimation and the cost function shown above. As S is increased the standard error in estimating BP in single subjects was substantially reduced allowing measurement in BP in thalamus, cortex, brain stem, etc. Additional studies demonstrate that a range of S values exist for which the bias is not excessive, even when parameter values differ markedly from the sample mean. This method can be used with any kinetic model so long as it is possible to compute a map of a priori mean parameters and their variances. (C) 2009 Elsevier Inc. All rights reserved.

AB Objective: Hypothermia has long been known to be a potent neuroprotectant. In this mini-review, we highlighted clinical experience that hypothermia protects the brain from cerebral injury. We discussed the clinical practice of hypothermia in ischemic stroke.
Results: Multiple factors play a significant role in the mechanisms. Clinical application drew first from two clinical trials with comatose patients after cardiac arrest is attractive. The Australian and European study have led to renewed interest in these patients. More and more evidences bring the insight into its effects on cerebral ischemia. The type of cooling technique to be used, the duration of cooling and speed of rewarming appear to be key factors in determining whether hypothermia is effective in preventing or mitigating neurological injury. Although until now, there are no clear therapeutic standards of the parameters in therapeutic hypothermia, it is well accepted that cooling should be initiated as soon as possible. By combining hypothermia with other neuroprotectants, it may be possible to enhance protective effects, reduce side effects and lengthen the maximum time.
Conclusion: In addition to its neuroprotective properties, hypothermia may extend the therapeutic window for other neuroprotective treatment. Thus, combination therapies with neuroprotective, anti-inflammatory and thrombolytic agents are likely to be investigated in the clinical setting in the future. [Neurol Res 2009; 31: 331-335]

AB Compromised neurocognition is a core feature of schizophrenia. Following Heinrichs and Zakzanis's (1998) seminal meta-analysis of middle-aged and predominantly chronic schizophrenia samples, the aim of this study is to provide a meta-analysis of neurocognitive findings from 47 studies of first-episode (FE) schizophrenia published through October 2007. The meta-analysis uses 43 separate samples of 2,204 FE patients with a mean age of 25.5 and 2,775 largely age- and gender-matched control participants. FE samples demonstrated medium-to-large impairments across 10 neurocognitive domains (mean effect sizes from -0.64 to -1.20). Findings indicate that impairments are reliably and broadly present by the FE, approach or match the degree of deficit shown in well-established illness, and are maximal in immediate verbal memory and processing speed. Larger IQ impairments in the FE compared to the premorbid period, but comparable to later phases of illness suggests deterioration between premorbid and FE phases followed by deficit stability at the group level. Considerable heterogeneity of effect sizes across studies, however, underscores variability in manifestations of the illness and a need for improved reporting of sample characteristics to support moderator variable analyses.

TI The power of partnership: Addressing cancer health disparities through
an academic-service partnership
SO NURSING OUTLOOK
LA English
DT Article
AB Partnerships between universities and healthcare organizations help foster interdisciplinary collaboration and can yield programs to address pressing needs in both sectors. In spite of these benefits, such partnerships remain more the exception than the norm. This article describes a partnership between a comprehensive cancer center and a university-based college of nursing and health sciences that serves a diverse student population. With the support of U-56 funding, the 2 organizations collaborated to develop a new, 87-credit BS-to-PhD in Nursing program and to enhance the university's traditional PhD in nursing program. Both PhD programs prepare nurses for careers in teaching, health policy, and research related to cancer health disparities. In addition to an innovative curriculum, the programs include a mentorship that leverages the research expertise and scholarly resources of both organizations and a community outreach component that gives students experience in planning and implementing educational and risk-reduction programs addressing cancer health disparities.

AB Combination of chemopreventive agents with distinct molectilar mechanisms is considered to offer a potential for enhancing cancer prevention efficacy while minimizing toxicity. Here we report two chemopreventive agents, selenite and genistein, that have synergistic effects on apoptosis, cell cycle arrest, and associated signaling pathways in p53-expressing LNCaP and p53-null PC3 prostate cancer cells. We show that selenite induced apoptosis only, whereas genistein induced both apoptosis and G(2)/M cell cycle arrest. Combination of these two agents exhibited enhanced effects, which were slightly greater in LNCaP than PC3 cells. Selenite or genistein alone upregulated protein levels of p53 in LNCaP cells only and p21(waf1) and Bax in both cell lines. Additionally, genistein inhibited AKT phosphorylation. Downregulation of AKT by siRNA caused apoptosis and G2/M cell cycle arrest and masked the effects of genistein. Treatment with insulin-like growth factor I (IGF-I) elevated levels of total and phosphorylated AKT and suppressed the effects of genistein. Neither downregulation of AKT nor IGF-I treatment altered the cellular effects of selenite. Our study demonstrates that selenium and genistein act via different molecular mechanisms and exhibit enhanced anticancer effects, suggesting that a combination of selenium and genistein may offer better efficacy and reduction of toxicity in prostate cancer prevention.

AB Rapid shifts in the demographics and techniques of weight loss surgery (WLS) have led to new issues, new data, new concerns, and new challenges. In 2004, this journal published comprehensive evidence-based guidelines on WLS. In this issue, we've updated those guidelines to assure patient safety in this fast-changing field. WLS involves a uniquely vulnerable population in need of specialized resources and ongoing multidisciplinary care. Timely best-practice updates are required to identify new risks, develop strategies to address them, and optimize treatment. Findings in these reports are based on a comprehensive review of the most current literature on WLS; they directly link patient safety to methods for setting evidence-based guidelines developed from peer-reviewed scientific publications. Among other outcomes, these reports show that WLS reduces chronic disease risk factors, improves health, and confers a survival benefit on those who undergo it. The literature also shows that laparoscopy has displaced open surgery as the predominant approach; that government agencies and insurers only reimburse procedures performed at accredited WLS centers; that best practice care requires close collaboration between members of a multidisciplinary team; and that new and existing facilities require wide-ranging changes to accommodate growing numbers of severely obese patients. More than 100 specialists from across the state of Massachusetts and across the many disciplines involved in WLS came together to develop these new standards. We expect them to have far-reaching effects of the development of health care policy and the practice of WLS.

AB The objective of this study is to update evidence-based best practice guidelines for multidisciplinary care of weight loss surgery (WLS) patients. We performed systematic search of English-language literature on WLS, patient selection, and medical, multidisciplinary, and nutritional care published between April 2004 and May 2007 in MEDLINE and the Cochrane Library. Key words were used to narrow the search for a selective review of abstracts, retrieval of full articles, and grading of evidence according to systems used in established evidence-based models. A total of 150 papers were retrieved from the literature search and 112 were reviewed in detail. We made evidence-based best practice recommendations from the most recent literature on multidisciplinary care of WLS patients. New recommendations were developed in the areas of patient selection, medical evaluation, and treatment. Regular updates of evidence-based recommendations for best practices in multidisciplinary care are required to address changes in patient demographics and levels of obesity. Key factors in patient safety include comprehensive preoperative medical evaluation, patient education, appropriate perioperative care, and long-term follow-up.

AB The objective of this study is to update evidence-based best practice guidelines for psychological evaluation and treatment of weight loss surgery (WLS) patients. We performed a systematic search of English-language literature on WLS and mental health, quality of life, and behavior modification published between April 2004 and May 2007 in MEDLINE and the Cochrane Library. Key words were used to narrow the search for a selective review of abstracts, retrieval of full articles, and grading of evidence according to systems used in established evidence-based models. Our literature search identified 17 articles of interest; 13 of the most relevant were reviewed in detail. From these, we developed evidence-based best practice recommendations on the psychological assessment and treatment of WLS patients. Regular updates of evidence-based recommendations for best practices in psychological care are required to address the impact of mental health on short- and long-term outcomes after WLS. Key factors in patient safety include comprehensive preoperative evaluation, use of appropriate and reliable evaluation instruments, and the development of short- and long-term treatment plans.

AB To update evidence-based best practice guidelines for obtaining informed consent from weight loss surgery (WLS) patients, with an emphasis on appropriate content and communications approaches that might enhance patient understanding of the information, we performed a systematic search of English-language literature published between April 2004 and May 2007 in MEDLINE and the Cochrane database. Keywords included WLS and informed consent, comprehension, health literacy, and patient education; and WLS and outcomes, risk, patient safety management, and effectiveness. Recommendations are based on the most current literature and the consensus of the expert panel; they were graded according to systems used in established evidence-based models. We identified over 120 titles, 38 of which were reviewed in detail. Evidence suggests that WLS outcomes, including long-term rates of relapse, vary by procedure. For some weight loss surgeries, long-term outcomes may not be known. Risks also vary by patient and provider characteristics. Informed consent should incorporate realistic projections of the short- and long-term risks, benefits, and consequences of surgery, as well as alternatives to WLS. For consent to be informed, the education process should continue until the patient demonstrates comprehension of all relevant material and concepts. Confirmation of comprehension can protect patients engaged in the process of consent for WLS. Future research should focus on the outcomes and consequences of WLS, and different approaches that facilitate patient understanding of, and decision making about, WLS.

AB To reevaluate and update evidence-based best practice recommendations published in 2004 for anesthetic perioperative care and pain management in weight loss surgery (WLS), we performed a systematic search of English-language literature on anesthetic perioperative care and pain management in WLS published between April 2004 and May 2007 in MEDLINE and the Cochrane Library. We identified relevant abstracts by using key words, retrieved full text articles, and stratified the resulting evidence according to systems used in established evidence-based models. We updated prior evidence-based best practice recommendations based upon interim literature. In instances of controversial or inadequate scientific evidence, the task force reached consensus recommendations following evaluation of the best available information and expert opinion. The search yielded 1,788 abstracts, with 162 potentially relevant titles; 45 were reviewed in detail. Despite more information on perioperative management of patients with obstructive sleep apnea (OSA), evidence to support preoperative testing and treatment or to guide perioperative monitoring is scarce. New evidence on appropriate intraoperative dosing of muscle relaxants allows for greater precision in their use during WLS. A novel application of alpha-2 agonists for perioperative anesthetic care is emerging. Key elements that may enhance patient safety include integration of the latest evidence on WLS, obesity, and collaborative multidisciplinary care into clinical care. However, large gaps remain in the evidence base.

AB The objective of this study is to update evidence-based best practice guidelines for pediatric/adolescent weight loss surgery (WLS). We performed a systematic search of English-language literature on WLS and pediatric, adolescent, gastric bypass, laparoscopic gastric banding, and extreme obesity published between April 2004 and May 2007 in PubMed, MEDLINE, and the Cochrane Library. Keywords were used to narrow the search for a selective review of abstracts, retrieval of full articles, and grading of evidence according to systems used in established evidence-based models. In light of evidence on the natural history of obesity and on outcomes of WLS in adolescents, guidelines for surgical treatment of obesity in this age group need to be updated. We recommend modification of selection criteria to include adolescents with BMI >= 35 and specific obesity-related comorbidities for which there is clear evidence of important short-term morbidity (i.e., type 2 diabetes, severe steatohepatitis, pseudotumor cerebri, and moderate-to-severe obstructive sleep apnea). In addition, WLS should be considered for adolescents with extreme obesity (BMI >= 40) and other comorbidities associated with long- term risks. We identified >1,085 papers; 186 of the most relevant were reviewed in detail. Regular updates of evidence-based recommendations for best practices in pediatric/adolescent WLS are required to address advances in technology and the growing evidence base in pediatric WLS. Key considerations in patient safety include carefully designed criteria for patient selection, multidisciplinary evaluation, choice of appropriate procedure, thorough screening and management of comorbidities, optimization of long-term compliance, and age-appropriate fully informed consent.

AB To update evidence-based best practice guidelines for coding and reimbursement and establish policy and access standards for weight loss surgery (WLS). Systematic search of English-language literature on WLS and health-care policy, access, insurance reimbursement, coding, private payers, public policy, and mandated benefits published between April 2004 and May 2007 in MEDLINE, EMBASE, and the Cochrane Library. Use of key words to narrow the search for a selective review of abstracts, retrieval of full articles, and grading of evidence according to systems used in established evidence-based models. We identified 51 publications in our literature search; the 20 most relevant were examined in detail. These included reviews, cost-benefit analyses, and trend and cost studies from administrative databases. Literature on policy issues surrounding WLS are very sparse and largely focused on economic analyses. Reports on policy initiatives in the public and private arenas are primarily limited to narrative reviews of nonsurgical efforts to fight obesity. A substantial body of work shows that WLS improves or reverses most obesity-related comorbidities. Mounting evidence also indicates that WLS confers a significant survival advantage for those who undergo it. WLS is a viable and cost-effective treatment for an increasingly common disease, and policy decisions are more frequently being linked to incentives for national health-care goals. However, access to WLS often varies by payer and region. Currently, there are no uniform criteria for determining patient appropriateness for surgery.

AB To update evidence-based best practice guidelines for collection of data on weight loss surgery (WLS). Systematic search of English-language literature in MEDLINE and the Cochrane Library on WLS and data collection, registries, risk adjustment, accreditation, benchmarks, and administrative and outcomes databases published between April 2004 and May 2007. Use of key words to narrow the search for a selective review of abstracts, retrieval of full articles, and grading of evidence according to systems used in established evidence-based models. During our search, we identified 212 papers; the 63 most relevant were reviewed in detail. Most data collection on WLS has relied on administrative data sets, single-institution studies, and other sources that are not WLS specific. A six-center, nationwide study involving data collection has been started by the longitudinal assessment of bariatric surgery, but results are not yet available. Two WLS-specific, longitudinal, national data collection systems are about to be implemented. Key factors in patient safety include data collection for all weight loss procedures; prospective, risk-adjusted, universal, benchmarked, longitudinal data collection systems; and use of WLS-specific data points that track clinical effectiveness and complications following WLS. Data collection will need to include assessments of novel therapies and specific subgroups (e.g., adolescents, the elderly, and individuals who are at the greatest risk or have the most to gain from WLS). Quality indicators, including metrics on processes of care and determination of outliers, need to be established and monitored to advance patient safety and quality improvement.

AB In this paper we review the state-of-the-art in endoscopic interventions for obesity treatment and make best practice recommendations for weight loss surgery (WLS). We performed a systematic search of English-language literature published between April 2004 and June 2008 in MEDLINE and the Cochrane Library on WLS and endoscopic interventions, endoscopically placed devices, minimally invasive surgery, image-guided surgery, endoluminal surgery, endoscopic instrumentation, interventional gastroenterology, transluminal surgery, and natural orifice transluminal surgery. We also searched the literature on endoscopic interventions and WLS and patient safety. We identified 36 pertinent articles, all of which were reviewed in detail; assessed the current science in endoscopic interventions for WLS; and made best practice recommendations based on the latest available evidence. Our findings indicate that endoscopic interventions and endoscopically placed devices may provide valuable approaches to the management of WLS complications and the primary management of obesity. Given the rapid changes in endoscopic technologies and techniques, systematic literature review is required to address issues related to the emerging role of endoluminal surgery in the treatment of obesity. These interventions should be a high priority for development and investigation.

AB Current, high-quality data are needed to evaluate the health impact of the epidemic of obesity in Latin America. The Latin American Consortium of Studies of Obesity (LASO) has been established, with the objectives of (i) Accurately estimating the prevalence of obesity and its distribution by sociodemographic characteristics; (ii) Identifying ethnic, socioeconomic and behavioural determinants of obesity; (iii) Estimating the association between various anthropometric indicators or obesity and major cardiovascular risk factors and (iv) Quantifying the validity of standard definitions of the various indexes of obesity in Latin American population. To achieve these objectives, LASO makes use of individual data from existing studies. To date, the LASO consortium includes data from 11 studies from eight countries (Argentina, Chile, Colombia, Costa Rica, Dominican Republic, Peru, Puerto Rico and Venezuela), including a total of 32 462 subjects. This article describes the overall organization of LASO, the individual studies involved and the overall strategy for data analysis. LASO will foster the development of collaborative obesity research among Latin American investigators. More important, results from LASO will be instrumental to inform health policies aiming to curtail the epidemic of obesity in the region.

TI Evaluating Methotrexate Treatment in Patients With Low-Risk Postmolar
Gestational Trophoblastic Neoplasia
SO OBSTETRICAL & GYNECOLOGICAL SURVEY
LA English
DT Editorial Material
AB The response of low-risk persistent gestational trophoblastic neoplasia (GTN) to methotrexate (MTX) monotherapy is close to 100%. With use of various MTX regimens, 48%-92% of patients go into remission. There is limited data on potential clinical risk factors indicating the need for additional courses of MTX or alternative chemotherapy following an initial course of MTX. This retrospective observational study identified possible clinical factors predictive of the requirement for additional MTX or alternative chemotherapy to obtain a remission in patients with postmolar low-risk GTN who had received MTX initially. Data was analyzed for 1801 women diagnosed with molar pregnancies between 1973 and 2003. Of the 150 women in the final study population, 110 had been diagnosed as complete mole and 40 as partial mole, and all had received MTX as initial therapy for GTN. All women had low-risk disease according to the combined International Federation of Obstetrics and Gynecology (FIGO) stage and the World Health Organization prognostic scores. Remission was defined as achievement and maintenance of undetectable serum beta human chorionic gonadotropin (beta-hCG) levels for 1 year.
All 150 patients ultimately achieved remission. Of the 70 women (47%) requiring additional courses of chemotherapy including MTX, 45 (64%) required alternative chemotherapy. Multivariate analysis showed that independent prognostic factors predicting increased risk of requiring additional MTX or alternative chemotherapy were complete mole histology, presence of metastasis, single day MTX infusion and any increase in beta-hCG levels 1 week after MTX therapy. Dilatation and curettage within 1 week after the diagnosis of persistence was not an independent risk factor for additional or alternative chemotherapy. For GTN following complete mole, beta-hCG levels >= 2000 mIU/ml at 1 week post-MTX were associated with an 89% risk of requiring additional MTX chemotherapy and a 64% risk of alternative chemotherapy to achieve remission.
These data identify several independent risk factors that predispose women with low-risk GTN to require additional MTX cycles and alternative chemotherapy after initial MTX.

TI Acylated Ghrelin and Leptin in Adolescent Athletes With Amenorrhea,
Eumenorrheic Athletes and Controls: A Cross-Sectional Study
SO OBSTETRICAL & GYNECOLOGICAL SURVEY
LA English
DT Editorial Material
AB Previous reports suggest that adolescent endurance athletes such as gymnasts and swimmers may be at higher risk of amenorrhea (AA) than other adolescent athletes. Neuroendocrine factors that differentiate athletes with AA from eumenorrheic athletes (EA) have been investigated but are not completely understood.
Two neuroendocrine peptides, leptin and ghrelin, appear to be involved in regulation of the hypothalamo-pituitary-gonadal axis. Low leptin levels and high ghrelin levels have been implicated in the occurrence of amenorrhea in adult athletes. The investigators hypothesized that blood levels of leptin and/or ghrelin could predict levels of gonadal steroids in adolescent athletes and identify which will develop ammenorhea. This cross-sectional study compared the levels of leptin, ghrelin, and gonadal steroids among adolescent athletes with AA, EA, and nonathletic controls at a large urban hospital. The study enrolled 58 adolescent girls, 12-18 years old, including 21 AA, 19 EA and 18 nonathletic controls. There was no history of amenorrhea or menarchal delay in the nonathletic controls. Active ghrelin, leptin, estrogen (E(2)), and testosterone were measured in fasting blood.
The body mass index (BMI) in AA was significantly lower than among EA and controls at baseline (P = 0.003). Log active ghrelin levels were significantly higher in AA compared to the other two groups (P < 0.0001); the difference was maintained after controlling for BMI Z-scores (P = 0.0007). Leptin levels were lower in AA compared to the other two groups (P < 0.0001), but did not remain significant after controlling for BMI Z-scores. Total testosterone levels were lower among AA compared to the EA and controls (P = 0.002), and the differences remained significant after controlling for BMI Z-scores (P = 0.03. There was a significant trend for lower E(2) scores among AA than the EA (P = 0.07), but the effect was not significant after controlling for BMI Z-scores. Inverse associations of log active ghrelin with testosterone were noted (P = 0.05), whereas there were positive associations of leptin with testosterone (P = 0.05) and log E(2) (P = 0.01).
These data show that ghrelin and leptin are independent predictors of levels of gonadal steroids. The investigators conclude from these findings that lower leptin levels and especially higher ghrelin levels may predict which athletes will develop amenorrhea.

TI Weight Loss to Treat Urinary Incontinence in Overweight and Obese Women
SO OBSTETRICAL & GYNECOLOGICAL SURVEY
LA English
DT Editorial Material
AB Obesity is a strong risk factor for urinary incontinence. Although marked weight loss after bariatric surgery in morbidly obese women was associated in previous studies with a reduction in urinary incontinence, the overall evidence for a benefit of weight loss in obese women is inconclusive. In this randomized clinical trial, the Program to Reduce Incontinence by Diet and Exercise, the potential benefits of a behavioral weight-reduction intervention were compared with a structured educational program in 338 overweight and obese women with at least 10 urinary incontinence episodes per week. The study subjects were randomized to receive either an intensive 6-month weight-loss program that included diet, exercise, and behavior modification (intervention group, n = 226) or a structured education program consisting of general information about healthy eating, physical activity, and weight loss (control group, n = 112). The mean (+/- SD) age of the study subjects was 53 +/- 11 years. Body-mass index (BMI) was calculated as the weight in kilograms divided by the square of the height in meters. The primary study outcome was the change in the total number of self-reported incontinence episodes of any type (including stress and urge incontinence) recorded in a 7-day voiding diary at 6 months after randomization.
At baseline, the mean BMI and the total number of incontinence episodes per week were the same in the intervention and control groups (BMI, 36 6 vs. 36 5, respectively; incontinence episodes, 24 18 vs. 24 16, respectively). At 6 months, the mean weight loss among women in the intervention group was 8.0% (7.8 kg), whereas the mean weight loss among women in the control group was 1.6% (1.5 kg) (P < .001). There was a greater decrease in total number of incontinence episodes per week in the intervention group at 6 months compared with the control group (intervention: 47.4% vs. control: 28.1%, P = 0.01). The frequency of stress incontinence episodes was reduced more in the intervention group (57.6%) than the control group (32.7%, P = 0.02). The frequency of episodes of urge incontinence was also decreased more in the intervention group (42.4% vs. 26.0%), but the difference was not statistically significant (P = 0.14). In comparison with the control group, a higher proportion of women in the intervention group reported a clinically meaningful reduction of at least 70% in the total weekly number of episodes of any type of incontinence (P < 0.001), stress-incontinence (P = 0.009), and urge-incontinence (P = 0.04).
The investigators conclude from these findings that weight loss should be considered as a first-line treatment in overweight and obese women with incontinence.

AB A basal cell carcinoma of the eyelid had unique and potentially confusing histopathologic features. The tumor displayed a carcinoma in situ pattern with replacement of an extensive segment of the tarsal epithelium by neoplastic basaloid cells, a finding to the best of the authors' knowledge that has not been previously documented. Within the infiltrating component of the dermis were classical solid basaloid nests and lobules; they were accompanied, however, by a separate and exceptionally prominent component of duct-like (pseudoglandular) units mimicking a microcystic adnexal carcinoma.

DT Editorial Material
AB Here we propose a different approach to hearing aids, an approach that flows logically from the pathophysiology of cochlear disorders. This approach challenges some central tenets of the industry by 1) suggesting that many, if not most, cases would be better served by flat, undistored gain across all frequencies rather than by "fitting" gain to the audiogram; and 2) suggesting that most of the improvements in hearing aid technology are targeted at reducing patient complaints as opposed to increasing measurable word recognition performance. We recommend that it is better to accommodate the damaged cochlea in these cases than to attempt to reverse-engineer the audiometric test results.

AB Preclinical studies have suggested that opioid exposure may induce a paradoxical decrease in the nociceptive threshold, commonly referred as opioid-induced hyperalgesia (OIH). While OIH may have implications in acute and chronic pain management, its clinical features remain unclear. Using an office-based quantitative sensory testing (QST) method, we compared pain threshold, pain tolerance, and the degree of temporal summation of the second pain in response to thermal stimulation among three groups of subjects; those with neither pain nor opioid therapy (group 1), with chronic pain but without opioid therapy (group 2), and with both chronic pain and opioid therapy (group 3). We also examined the possible correlation between QST responses to thermal stimulation and opioid dose, opioid treatment duration, opioid analgesic type, pain duration, or gender in group 3 subjects. As compared with both group 1 (n = 41) and group 2 (n = 41) subjects, group 3 subjects (n = 58) displayed a decreased heat pain threshold and exacerbated temporal summation of the second pain to thermal stimulation. In contrast, there were no differences in cold or warm sensation among three groups. Among clinical factors, daily opioid dose consistently correlated with the decreased heat pain threshold and exacerbated temporal summation of the second pain in group 3 subjects. These results indicate that decreased hear pain threshold and exacerbated temporal summation of the second pain may be characteristic QST changes in subjects with opioid therapy. The data suggest that QST may be a useful tool in the clinical assessment of OIH. (C) 2009 International Association for the Study of Pain. Published by Elsevier B.V. All rights reserved.

AB The study aimed to compare the psychological and physical characteristics of older adults with knee osteoarthritis (OA) vs those of adults with chronic low back pain (CLBP) and to identify psychological and physical predictors of function as measured by gait speed.
Secondary data analysis.
Eighty-eight older adults with advanced knee OA and 200 with CLBP who had participated in separate randomized controlled trials were selected for this study.
Inclusion criteria for both trials included age >= 65 and pain of at least moderate intensity that occurred daily or almost every day for at least the previous 3 months. Psychological constructs (catastrophizing, fear avoidance, self-efficacy, depression, affective distress) and physical measures (comorbid medical conditions, pain duration, pain severity, pain related interference, self-rated health) were obtained.
Subjects with CLBP had slower gait (0.88 m/s vs 0.96 m/s, P = 0.002) and more comorbid conditions than subjects with knee pain (mean 3.36 vs 1.97, P < 0.001). All the psychological measures were significantly worse in the CLBP group except the Multidimensional Pain Inventory-Affective Distress score. Self-efficacy, pain severity, and medical comorbidity burden were associated with slower gait regardless of the location of the pain.
Older adults with chronic pain may have distinct psychological and physical profiles that differentially impact gait speed. These findings suggest that not all pain conditions are the same in their psychological and physical characteristics and may need to be taken into consideration when developing treatment plans.

AB Diagnosis is a critical component of health care. The world of diagnostic tests is highly dynamic. New tests are developed at a fast pace and technology of existing tests is continuously being improved. However, clinicians, policy makers, and patients routinely face a range of questions regarding diagnostic tests. Well designed diagnostic test accuracy studies can help in making these decisions, provided that they transparently and fully report their participants, tests, methods, and results (as facilitated). For example, by the standards for the reporting of diagnostic accuracy studies (STARD) statement.
Exaggerated and biased results from poorly designed and reported diagnostic test studies can trigger their premature dissemination and lead physicians into making in a diagnostic test is useful only to the extent that it correct treatment decisions. Thus, distinguishes between conditions or disorders that might otherwise be confused. While almost any test can differentiate healthy persons from severely affected ones, appropriate diagnostic tests should differentiate mild and moderate forms of disease.
Shortcomings in a study design and interpretation can affect estimates of diagnostic accuracy. Thus, quality diagnostic studies are essential in medicine in general and interventional pain management in particular. The STARD initiative was developed to improve the accuracy and completeness in the reporting of studies of diagnostic accuracy and provide guidance to assist in reducing the potential for bias in the study and to evaluate a study's generalizability.
In the practice of interventional pain management, in addition to diagnostic tests which include laboratory tests, imaging tests, and physical examination, diagnostic interventional techniques are crucial. Interventional techniques as a diagnostic tool in painful conditions is important due to multiple challenging clinical situations, which include the purely subjective nature of pain and underdetermined and uncertain pathophysiology in most painful spinal conditions. Precision diagnostic blocks are used to clarify these challenging clinical situations in order to determine the pathophysiology of clinical pain, the site of nociception, and the pathway of afferent neural signals.
Part 5 of evidence-based medicine (EBM) in interventional pain management describes the various aspects of diagnostic accuracy studies.

FOLLOW-UP
AB Background: Lumbar disc prolapse, protrusion, or extrusion account for less than 5% of all low problems but are the most common causes of nerve root pain and surgical interventions., The primary rationale for any form of surgery for disc prolapse is to relieve nerve root irritation or compression due to herniated disc material. The primary modality of treatment continues to be either open or microdiscectomy, but several alternative techniques including nucleoplasty, automated percutaneous discectomy, and laser discectomy have been described. There is a paucity of evidence for all decompression techniques, specifically alternative techniques including nucleoplasty.
Study Design: A systematic review of the literature.
Objective: To determine the effectiveness of mechanical lumbar disc decompression with nucleoplasty.
Methods: A comprehensive evaluation of the literature relating to mechanical lumbar disc decompression with nucleoplasty was performed. The literature was evaluated according to Cochrane review criteria for randomized controlled trials (RCTs), and Agency for Healthcare Research and Quality (AHRQ) criteria was utilized for observational studies. The level of evidence was classified as Level I, II, or III with 3 subcategories in Level II based on the quality of evidence developed by the United States Preventive Services Task Force (USPSTF). A literature search was conducted using only English language literature through PubMed, EMBASE, the Cochrane library, systematic reviews, and cross-references from reviews and systematic reviews.
Outcome Measures: Pain relief was the primary outcome measure. Other outcome measures were functional improvement, improvement of psychological status, opioid intake, and return to work. Short-term effectiveness was defined as one year or less, whereas, long-term effectiveness was defined as greater than one year.
Results: Based on USPSTF criteria the level of evidence for nucleoplasty is Level II-3 in managing predominantly lower extremity pain due to contained disc herniation.
Limitations: Paucity of literature, both observational and randomized.
Conclusion: This systematic review illustrates Level II-3 evidence for mechanical lumbar percutaneous disc decompression with nucleoplasty in treatment of leg pain. However, there is no evidence available in managing axial low back pain.

SYNDROME
AB Background: Since the descriptions by Mixter and Barr of open surgical treatment for rupture of the intervertebral disc in 1934, open surgical procedures have become a common practice. Disc herniations have been reported as being contained and non-contained. The results of open surgical discectomy for contained disc herniation have been poor. Consequently, several alternative techniques have been developed which are minimally invasive including percutaneous laser disc decompression.
Study Design: A systematic review of the literature.
Objective: The objective of this systematic review is to evaluate the clinical effectiveness of percutaneous laser discectomy in managing radicular pain secondary to contained disc herniation.
Methods: A comprehensive evaluation of the literature relating to mechanical disc decompression was performed. The literature was evaluated according to Cochrane review criteria for randomized controlled trials (RCTs), and Agency for Healthcare Research and Quality (AHRQ) criteria was utilized for observational studies.
A literature search was conducted by using only the English language literature through PubMed, EMBASE, the Cochrane library, systematic reviews, and cross references from reviews and systematic reviews.
The level of evidence was classified as Level I, II, or III with 3 subcategories in Level II based on the quality of evidence developed by the United States Preventive Services Task Force (USPSTF).
Outcome Measures: Pain relief was the primary outcome measure. Other outcome measures were functional improvement, improvement of psychological status, opioid intake, and return to work.
Short-term effectiveness was defined as one year or less, whereas, long-term effectiveness was defined as greater than one year.
Results: Based on USPSTF criteria the indicated level of evidence for percutaneous lumbar laser discectomy (PLLD) is II-2 for short- and long-term relief.
Limitations: Even though laser discectomy has been in utilization for a number of years and numerous procedures have been performed there continues to be a paucity of literature of randomized clinical trials.
Conclusion: This systematic review illustrates Level II-2 evidence for percutaneous laser disc decompression which is equivalent to automated percutaneous lumbar disc decompression.

AB Background: Lumbar disc prolapse, protrusion, and extrusion account for less than 5% of all low back problems, but are the most common causes of nerve root pain and surgical interventions. The typical rationale for traditional surgery is an effort to provide more rapid relief of pain and disability. It should be noted that the majority of patients will recover with conservative management. The primary rationale for any form of surgery for disc prolapse associated with radicular pain is to relieve nerve root irritation or compression due to herniated disc material. The primary modality of treatment continues to be either open or microdiscectomy, but several alternative techniques including automated percutaneous lumbar discectomy (APLD) have been described. However, there is a paucity of evidence for all decompression techniques, specifically alternative techniques including automated and laser discectomy.
Study Design: A systematic review of the literature.
Objective: To determine the effectiveness of APLD.
Methods: A comprehensive evaluation of the literature relating to automated lumbar disc decompression was performed. The literature was evaluated according to Cochrane review criteria for randomized controlled trials (RCTs), and Agency for Healthcare Research and Quality (AHRQ) criteria was utilized for observational studies.
A literature search was conducted of English language literature through PubMed, EMBASE, the Cochrane library, systematic reviews, and cross references from reviews and systematic reviews.
The level of evidence was classified as Level I, II, or III with 3 subcategories in Level II based on the quality of evidence developed by the United States Preventive Services Task Force (USPSTF).
Outcome Measures: Pain relief was the primary outcome measure. Other outcome measures were functional improvement, improvement of psychological status, opioid intake, and return to work.
Short-term effectiveness was defined as one-year or less, whereas, long-term effectiveness was defined as greater than one-year.
Results: Based on USPSTF criteria, the indicated evidence for APLD is Level II-2 for short- and long-term relief.
Limitations: Paucity of RCTs in the literature.
Conclusion: This systematic review indicated Level II-2 evidence for APLD. APLD may provide appropriate relief in properly selected patients with contained lumbar disc prolapse.

AB Objective: The objective of this study was to examine the separate contributions of patients and physicians to their communication regarding cancer screening.
Methods: Research design and subjects: The authors conducted a cross-sectional analysis of survey data collected from 63 community-based primary care physicians and 904 of their female patients in Los Angeles.
Results: Patients who perceived their physicians to be enthusiastic (at any level) in their discussions of mammography or fecal occult blood tests (FOBT) were significantly more likely to report a recent test than patients who reported no discussions.
Conclusion: Physician discussions of cancer screening are important and effective even when, as in the case of mammography, screening rates are already high, or. as in the case of FOBT. rates have tended to remain low. The value of communication about screening should be taught and promoted to primary care physicians who serve as gatekeepers to screening.
Practice implications: Those who train physicians in communication skills should take into account our finding that the communication style of physicians (e.g., enthusiasm for screening) was the only patient or physician variable that both influenced screening adherence and that could be taught.

AB Objectives: Compare the frequency of respiratory adverse events between patients who received intramuscular (IM) versus intravenous ketamine.
Methods: Case control study from 1997 to 2005 at a large urban pediatric emergency department. Adverse events were defined as apnea, hypoxemia (oximetry <93%), hypoventilation, laryngospasm, and other upper airway obstruction. Serious adverse events were defined by the level of intervention and included those cases that required positive pressure ventilation, insertion of oral or nasal airway, or endotracheal intubation. Minor adverse events were respiratory events requiring minimal intervention (stimulation, supplemental 02, airway repositioning). Controls (2: 1) were selected by the next chronological patient in the data set who received ketamine but had no respiratory adverse event.
Results: Four thousand two hundred fifty-two patients received ketamine; 102 cases (2.4%) had respiratory adverse events, including 38 patients with severe adverse events (0.9%). Interventions for the cases included supplemental 02 (59/102, 58%), airway repositioning (36/102, 35%), continuous positive airway pressure (7/102, 7%), positive pressure ventilation (33/102, 32%), nasal airway (2/102, 2%), oral airway (1/102, 1%), stimulation (11/102, 11%), and intubation (1/102, 1%). Overall, 33% of all subjects received IM ketamine including 47% of cases and 27% of controls. Intramuscular IM ketamine was associated with increased likelihood of adverse events (odds ratio [OR] 2.1, 95% Cl, 1.3-3). Twenty (69%) of the 29 patients with laryngospasm received IM ketamine (OR, 5.2; 95% CI, 2.3-11.9) and 20 (53%) of the 38 patients who had severe events were administered IM (OR, 2.4; 95% Cl, 1.2-4.9). Use of pre-sedation morphine or combined administration with midazolam and/or atropine was not associated with adverse events. Specific procedures were not associated with increased adverse events.
Conclusions: Respiratory adverse events with ketamine are uncommon. Serious events, like laryngospasm, are rare but occur more commonly with IM administration. This increased risk associated with IM administration should be considered in the sedation plan.

AB Megacalycosis is an extremely rare condition. We report our experience with two cases and discuss its pathogenesis, diagnosis and management in children. Our two patients had presented a prior diagnosis of congenital hydronephrosis. An increased number of calyces with a significant disproportion between the degree of calyceal dilatation and a mildly dilated renal pelvis were found in each case. Megacalycosis must be considered in the differential diagnosis of congenital hydronephrosis, polycalycosis, and infundibular stenosis. The diagnosis is suggested by ultrasound and confirmed by diuretic renography, intravenous pyelography or magnetic resonance urography. Voiding cystourethrography should be performed to rule out vesicoureteral reflux. A high index of suspicion is needed for the diagnosis of this condition.

AB Major chest trauma in a child is associated with significant morbidity and mortality. It is most frequently encountered within the context of multisystem injury following high-energy trauma such as a motor vehicle accident. The anatomic-physiologic make-up of children is such that the pattern of ensuing injuries differs from that in their adult counterparts. Pulmonary contusion, pneumothorax, haemothorax and rib fractures are most commonly encountered. Although clinically more serious and potentially life threatening, tracheobronchial tear, aortic rupture and cardiac injuries are seldom observed. The most appropriate imaging algorithm is one tailored to the individual child and is guided by the nature of the traumatic event as well as clinical parameters. Chest radiography remains the first and most important imaging tool in paediatric chest trauma and should be supplemented with US and CT as indicated. Multidetector CT allows for the accurate diagnosis of most traumatic injuries, but should be only used in selected cases as its routine use in all paediatric patients would result in an unacceptably high radiation exposure to a large number of patients without proven clinical benefit. When CT is used, appropriate modifications should be incorporated so as to minimize the radiation dose to the patient whilst preserving diagnostic integrity.

ID CONSTRUCTION; MODEL
AB Throughout the history of psychology, the path of transforming the physical (muscle movements, verbal behavior, or physiological changes) into the mental has been fraught with difficulty. Over the decades, psychologists have risen to the challenge and learned a few things about how to infer the mental from measuring the physical. The Vul, Harris, Winkielman, and Pashler article (2009, this issue) points out that some of these lessons could be helpful to those of us who measure blood flow in the brain in a quest to understand the mind. Three lessons from psychometrics are discussed.

AB Background: Studies have demonstrated that blocking a single specificity of self-reactive immunoglobulin M with a 12-amino acid peptide mimic of the antigen of immunoglobulin M can attenuate murine intestinal and skeletal muscle injury following ischemia and reperfusion. The aim of this study was to ascertain whether peptide (P8) had protective effects in an axial island skin flap model, where tissue loss is attributed to ischemia-reperfusion injury.
Methods: Dorsal lateral thoracic artery island skin flaps (3.5 X 1.5 cm) were elevated in 82 male C57BL/6 mice and rendered ischemic for 10 hours by placing a 7-mm microclamp on the vascular pedicle followed by 7 days of reperfusion. Group I (n = 7), the sham group, had no clamp placed. Group II (n = 21) had clamp placement but no other treatment. Thirty minutes before clamp placement, group III (n = 18) received 0.25 cc of saline intravenously, group IV (n = 18) received 25 mu g/0.25 cc P8 peptide, and group V (n = 7) received 25 mu g/0.25 cc random 12-mer peptide. Animals in group VI (n = 11) underwent two cycles of 20 minutes of ischemic preconditioning before 10 hours of ischemia. After 1 week of reperfusion, percent necrosis was measured and results were compared using analysis of variance and an unpaired t test.
Results: In animals treated with P8 peptide, flap necrosis was 14.61 +/- 2.77 percent. This represents a statistically significant, 56 percent reduction in flap necrosis compared with controls (p < 0.001). Conclusion: These data demonstrate that prevention of ischemia-reperfusion injury with P8 peptide produces a significant reduction in necrosis of treated flaps. (Plast. Reconstr. Surg. 123: 1431, 2009.)

AB The prevalence of obesity (body mass index (BMI) >= 30 kg/m(2)) is higher in African Americans than in European Americans, even after adjustment for socioeconomic factors, suggesting that genetic factors may explain some of the difference. To identify genetic loci influencing BMI, we carried out a pooled analysis of genome-wide admixture mapping scans in 15,280 African Americans from 14 epidemiologic studies. Samples were genotyped at a median of 1,411 ancestry-informative markers. After adjusting for age, sex, and study, BMI was analyzed both as a dichotomized (top 20% versus bottom 20%) and a continuous trait. We found that a higher percentage of European ancestry was significantly correlated with lower BMI (rho = -0.042, P = 1.6 x 10(-7)). In the dichotomized analysis, we detected two loci on chromosome X as associated with increased African ancestry: the first at Xq25 (locus-specific LOD = 5.94; genome-wide score = 3.22; case-control Z = -3.94); and the second at Xq13.1 (locus-specific LOD = 2.22; case-control Z = -4.62). Quantitative analysis identified a third locus at 5q13.3 where higher BMI was highly significantly associated with greater European ancestry (locus-specific LOD = 6.27; genome-wide score = 3.46). Further mapping studies with dense sets of markers will be necessary to identify the alleles in these regions of chromosomes X and 5 that may be associated with variation in BMI.

AB The innate immune response is supposed to play an essential role in the control of amebic liver abscess (ALA), a severe form of invasive amoebiasis due to infection with the protozoan parasite Entamoeba histolytica. In a mouse model for the disease, we previously demonstrated that J alpha 18(-/-) mice, lacking invariant natural killer T (iNKT) cells, suffer from more severe abscess development. Here we show that the specific activation of iNKT cells using alpha-galactosylceramide (alpha-GalCer) induces a significant reduction in the sizes of ALA lesions, whereas CD1d(-/-) mice develop more severe abscesses. We identified a lipopeptidophosphoglycan from E. histolytica membranes (EhLPPG) as a possible natural NKT cell ligand and show that the purified phosphoinositol (PI) moiety of this molecule induces protective IFN-gamma but not IL-4 production in NKT cells. The main component of EhLPPG responsible for NKT cell activation is a diacylated PI, (1-O-[(28: 0)-lyso-glycero-3-phosphatidyl-]2-O(C16:0)-Ins). IFN-gamma production by NKT cells requires the presence of CD1d and simultaneously TLR receptor signalling through MyD88 and secretion of IL-12. Similar to alpha-GalCer application, EhLPPG treatment significantly reduces the severity of ALA in ameba-infected mice. Our results suggest that EhLPPG is an amebic molecule that is important for the limitation of ALA development and may explain why the majority of E. histolytica-infected individuals do not develop amebic liver abscess.

TI Motor Learning of a Gait Pattern to Reduce Forefoot Plantar Pressures in
Individuals with Diabetic Peripheral Neuropathy
SO PM&R
LA English
DT Article
AB Objective: To examine the role of visual feedback in the reduction of plantar pressures through teaching a "new" gait pattern to diabetic peripheral neuropathy subjects. Immediate, next day, and 1-week retention were studied to determine if motor pattern changes could occur.
Design: Randomized controlled trial.
Setting: VA Urban Healthcare System.
Participants: Twenty-nine community-dwelling older adults with diabetic peripheral neuropathy volunteered.
Interventions: Subjects were randomized into feedback and no-feedback groups. All subjects received instruction and 2 days of practice and returned for a 1-week retention test. Instruction to pull the leg forward from the hip to initiate swing rather than push off the ground with the foot while walking was given to all subjects. The feedback group received visual feedback regarding peak plantar pressures after each practice trial. The no-feedback group received no feedback.
Main Outcome Measures: Peak plantar pressures in the forefoot region for immediate retention (retention 1), next day retention (retention 2), and long-term retention (1-week retention).
Results: Peak plantar pressures were significantly (P < .01) reduced from baseline to retention 2 testing at the first metatarsal area in the feedback group. The feedback group walked significantly (P < .01) slower at retention 1 and 1-week testing compared with baseline.
Conclusions: Individuals with diabetic peripheral neuropathy were unable to use a "new" strategy gait pattern to reduce peak plantar pressures long term (1 week). The use of visual feedback following the trial did not assist in the learning of a new walking pattern.

AB Therapy is often required to manage the hyperglycemia, hypertension, and dyslipidemia that occur in patients with type 2 diabetes mellitus (T2DM) in order to control the risk of cardiovascular (CV) events. The importance of managing these risk factors is underscored by the recommendation from the American Diabetes Association and the American Association of Clinical Endocrinologists for treatment of these CV risk factors to target levels. However, relatively few patients achieve simultaneous control of these risk factors. As such, therapy that has positive effects on more than I risk factor is of potential benefit. Initially approved as a lipid-lowering agent, the bile acid sequestrant colesevelam hydrochloride (HCl) is now also approved as an adjunct therapy to improve glycemic control in patients with T2DM. This review summarizes the major findings of clinical studies that investigated the glucose- and lipid-lowering effects of colesevelam HCl when added to stable metformin-, sulfonylurea-, or insulin-based antidiabetes therapies in patients with T2DM.

AB Background. Certain types of human papillomavirus (HPV) can cause cervical and other cancers. A vaccine that protects against HPV types responsible for 70% of cervical cancers is available to females ages 9-26.
Objective. To examine correlates of stage of vaccine adoption among women ages 18-22.
Methods. In 2007, female students (n = 4774) at a New England University in the U.S. were invited to complete an on-line survey that assessed knowledge of HPV, perceived susceptibility, severity, vaccine benefits/barriers, social and subjective norms, and stage of vaccine adoption
Results. 1897 women (40%) responded; complete data were available for 1401. About half (53%) were planning to be vaccinated, 12% had received the vaccine, 15% were undecided, and 7% had decided against vaccination. HPV knowledge was low (mean 58%). In multivariate analyses, social norms was the strongest correlate of stage; each standard deviation increase in social norms score was associated with more than four times the odds of intending to be vaccinated within the next 30 days, compared with those who had decided against vaccination (OR=4.15: 95% CI 2.17-6.36).
Conclusions. Acceptance of the vaccine was high, although misconceptions about viral transmission, availability of treatment, and the role of Pap tests were common. Perceived norms were strongly associated with intentions. Interventions on college campuses should stress vaccination as a normative behavior, provide information about viral transmission, and stress the role of continued Pap screening.

AB BACKGROUND. Macrophage inhibitory cytokine-1 (MIC-1) belongs to the bone morphogenic protein/transforming growth factor-beta (BMP/TGF-beta) superfamily. Serum MIC-1 concentrations are elevated in patients with advanced prostate cancer. The effects of MIC-1 on prostate cancer bone metastases are unknown.
METHODS. In vitro effects of MIC-1 on osteoblast differentiation and activity were analyzed with alkaline phosphatase and mineralization assays; osteoclast numbers were counted microscopically. MIC-1 effects on TLR9 expression were studied with Western blotting. Human Du-145 prostate cancer cells were stably transfected with a cDNA encoding for mature MIC-1 or with an empty vector. The in vivo growth characteristics of the characterized cells were studied with the intra-tibial model of bone metastasis. Tumor associated bone changes were viewed with X-rays, histology, and histomorphometry. Bone formation was assayed by measuring serum PINP.
RESULTS. MIC-1 induced osteoblast differentiation and activity and osteoclast formation in vitro. These effects were independent of TLR9 expression, which was promoted by MIC-1. Both MIC-1 and control tumors induced mixed sclerotic/lytic bone lesions, but MIC-1 increased the osteolytic component of tumors. Osteoclast formation at the tumor-bone interface was significantly higher in the MIC-1 tumors, whereas bone formation was significantly higher in the control mice. At sacrifice, the mice bearing MIC-1 tumors were significantly lighter with significantly smaller tumors.
CONCLUSIONS. MIC-1 up-regulates TLR9 expression in various cells. MIC-1 stimulates both osteoblast and osteoclast differentiation in vitro, independently of TLR9. MIC-1 over-expressing prostate cancer cells that grow in bone induce osteoclast formation and cachexia. Prostate 69: 652-661, 2009. (C) 2009 Wiley-Liss, Inc.

AB Human lung cancer is a major cause of cancer mortality worldwide. Advances in pathophysiologic understanding and novel biomarkers for diagnosis and treatment are significant tasks. We have undertaken a comprehensive glycoproteomic analysis of human lung adenocarcinoma tissues. Glycoproteins from paired lung adenocarcinoma and normal tissues were enriched by the lectins Con A, WGA, and AIL. 2-D PAGE revealed 30 differentially expressed protein spots, and 15 proteins were identified by MS/MS, including 8 up- (A1AT, ALDOA, ANXA1, CALR, ENOA, PDIA1, PSB1 and SODM) and 7 down-regulated (ANXA3, CAH2, FETUA, HBB, PRDX2, RAGE and VIME) proteins in lung cancer. By reverse-transcription PCR, nine proteins showed positive correlation between mRNA and glycoprotein expression. Vimentin and fetuin A (alpha(2)-HS-glycoprotein) were selected for further investigation. While for vimentin there was little correlation between total protein and mRNA abundance, expression of WGA-captured glycosylated vimentin protein was frequently decreased in cancer. Glycoarray analysis suggested that vimentins from normal and cancerous lung tissue differ in their contents of sialic acid and terminal GlcNAc. For fetuin A, both total protein and mRNA abundance showed concordant decrease in cancer. WGA- and AIL-binding glycosylated fetuin A was also consistently decreased in cancer. Glycoarray analysis suggested that high mannose glycan structures on fetuin A were only detectable in cancer but not normal tissue. The intriguing expression patterns of different isoforms of glycosylated vimentin and fetuin A in lung cancer illustrate the complexities and benefits of in-depth glycoproteomic analysis. In particular, the discovery of differentially glycosylated protein isoforms in lung adenocarcinoma may represent avenues towards new functional biomarkers for diagnosis, treatment guidance, and response monitoring.

AB Eating disorder not otherwise specified (EDNOS) is the most prevalent eating disorder (ED) diagnosis. In this meta-analysis, the authors aimed to inform Diagnostic and Statistical Manual of Mental Disorders revisions by comparing the psychopathology of EDNOS with that of the officially recognized EDs: anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). A comprehensive literature search identified 125 eligible studies (Published and unpublished) appearing in the literature from 1987 to 2007. Random effects analyses indicated that whereas EDNOS did not differ significantly from AN and BED on eating pathology or general psychopathology, BN exhibited greater eating and general psychopathology than EDNOS. Moderator analyses indicated that EDNOS groups who met all diagnostic criteria for AN except for amenorrhea did not differ significantly from full syndrome cases. Similarly, EDNOS groups who met all criteria for BN or BED except for binge frequency did not differ significantly from full syndrome cases. Results suggest that EDNOS represents a set of disorders associated with substantial psychological and physiological morbidity. Although certain EDNOS subtypes could be incorporated into existing Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) categories, others-such as purging disorder and non-fat-phobic AN-may be best conceptualized as distinct syndromes.

AB Background. DSM-IV cites <85% of expected body weight (EBW) as a guideline for the diagnosis of anorexia nervosa (AN) but does not require a specific method for calculating EBW. The purpose of the present Study was to determine the degree to which weight cut-off calculations vary across studies, and to evaluate whether differential cut-offs lead to discrepancies in the prevalence of individuals who are eligible for the AN diagnosis.
Method. Two coders independently recorded the EBW Calculation methods from 99 Studies that either (a) compared individuals with AN to those With subclinical eating disorders or (b) conducted AN treatment trials. Each weight Cutoff was applied to a nationally representative (n = 12001) and treatment-seeking (n = 189) sample to determine the impact of EBW calculation on the proportion who met the AN weight criterion.
Results. Coders identified 10 different EBW methods, each of which produced different weight cut-offs for the diagnosis of AN. Although only 0.23%, of the national sample met the lowest cut-off, this number increased 43-fold to 10.10% under the highest cut-off. Similarly, only 48.1% of treatment seekers met the lowest cut-off, whereas 89.4%, met the highest.
Conclusions. There is considerable variance across studies in the determination of the AN weight cut-off. Discrepancies Substantially affect the proportion of individuals who are eligible for diagnosis, treatment and insurance reimbursement. However, differences may not be fully appreciated because the ubiquitous citation of the 85%, criterion creates a sense of false consensus.

AB Both schizophrenia and oxidative stress have been associated with immune system abnormalities in interleukin-2 and -6 (IL-2; IL-6) and increases in superoxide dismutase (SOD) activity. These abnormalities may improve during antipsychotic drug treatment that reduces symptoms in schizophrenic patients.
Subjects included 30 healthy controls (HC) and 78 schizophrenic (SCH) in-patients who were randomly assigned to 12 weeks of double-blind treatment with risperidone 6 mg/day or haloperidol 20 mg/day. Ratings using the Positive and Negative Syndrome Scale (PANSS) were correlated with blood SOD and serum IL-2 levels.
SCH patients who were medication-free for 2 weeks had greater SOD, IL-2, and IL-6 levels than HC. At baseline, these SOD elevations were associated with higher PANSS total scores and the IL-2 elevations with lower PANSS positive symptom scores. The SOD and IL-2 levels in the SCH were also positively correlated. After treatment, PANSS positive symptoms and both SOD and IL-2 showed a significant decrease, but IL-6 showed no change. The SOD and IL-2 reductions were correlated with the reductions in PANSS total score, and SOD reductions also correlated with positive subscore reductions. Females showed these associations more strongly than males.
Our results suggest that the dysregulation in the cytokine system and oxidative stress in patients with schizophrenia is implicated in clinical symptoms and is improved at least partially with antipsychotic treatment. The stronger associations in females deserve further study and confirmation.

AB Recent research has provided evidence that the postauricular reflex (PAR) is potentiated while people view pleasant images relative to unpleasant and neutral images. The present study sought to extend these findings by investigating whether the PAR is more robustly modulated by the appetitive salience of the stimuli. Eyeblink startle and PAR responses of 51 participants were recorded while they viewed images that varied in valence and thematic content. Participants displayed significantly greater mean PAR magnitude during appetitive-related images (e.g., food, erotica, families) compared with non-appetitive-related pleasant images. These findings support the contention that the PAR is a useful tool for measuring appetitive responding in humans.

HELICAL CT; DISSECTION; DIAGNOSIS
AB Rupture of the vasa vasorum into the media of the aortic wall results in an aortic intramural hematoma. Characteristic findings of an aortic intramural hematoma include a crescentic hyperattenuating fluid collection at unenhanced computed tomography (CT) and a smooth, nonenhancing, thickened aortic wall at contrast material-enhanced CT. The CT appearance of untreated intramural hematomas evolves over time, and decreased attenuation is a clue to the chronicity of a hematoma. CT is particularly useful for evaluating aortic intramural hematomas because it allows their differentiation from aortic dissections, which have similar clinical manifestations, and permits an exact determination of their location-crucial information for surgical planning. On the basis of CT findings, some hematomas may be expected to resolve spontaneously, whereas others may be identified as posing a high risk for serious complications such as aortic dissection, aneurysm, and rupture. Appropriate clinical management is aided by accurate recognition of diagnostically specific CT features and awareness of their significance. (C) RSNA, 2009. radiographics.rsnajnls.org

AB The extensor mechanism of the knee is essential to ambulation and is subject to a number of traumatic, congenital, and inflammatory processes. In the pediatric population, the spectrum of pathologic conditions affecting the extensor mechanism is specific to skeletally immature patients. In addition, certain congenital and developmental disorders may further predispose the knee extensor mechanism to injury. The pathologic processes can be subdivided into categories: conditions of the attachments and insertions of the quadriceps and patellar tendons, conditions of the patella, conditions of the quadriceps muscle group, and avulsions of the superior attachments of the quadriceps. Cases of conditions affecting the extensor mechanism of the pediatric knee were collected at two large trauma centers, and the clinical and radiologic features were reviewed. Initial evaluation of these conditions is performed with radiography, but magnetic resonance imaging has evolved into a useful adjunct for assessing the soft tissues for a more precise evaluation of the true extent of an injury, thereby affecting decisions about surgical intervention and prognosis.

AB Although the translation of experimental molecular MR imaging agents is highly compelling, it is substantially more complex than the translation of radiolabeled imaging agents. The prognostic value, safety, and cost-effectiveness of molecular MR imaging for the detection of plaque inflammation will need to be demonstrated and will require a robust and collaborative effort among basic scientists, clinicians, epidemiologists, and industry. The well-conducted and valuable study reported by Amirbekian et al (1) in this issue of Radiology adds further momentum to this important endeavor.

SO RADIOLOGY
LA English
DT Article
ID METASTASES INVOLVING BONE; OSTEOID OSTEOMA; ELECTRODE
AB Purpose: To demonstrate that radiofrequency (RF) ablation can be used safely and effectively to treat selected cases of chondroblastoma.
Materials and Methods: Approval was obtained from institutional review boards, research was in compliance with HIPAA protocol. The need to obtain informed consent was waived for retrospective review of patient records. The records of patients with biopsy-proved chondroblastoma who were treated with RF ablation at two academic centers from July 1995 to July 2007 were reviewed. RF ablation was performed with a single-tip electrode by using computed tomography for guidance. Lesion characteristics were determined from imaging studies obtained at the time of the procedure. Symptoms were assessed before and 1 day after the procedure. Longer-term follow-up was obtained from medical records.
Results: Thirteen male and four female patients were treated (mean age, 17.3 years). The lesions were located in the proximal humerus (n = 7), proximal tibia (n = 4), proximal femur (n = 3), and distal femur (n = 3). The mean volume of the lesions was 2.46 mL. All patients reported relief of symptoms on postprocedure day 1. Three patients were lost to follow-up. Of the 14 patients for whom longer-term (mean, 41.3 months; range, 4-134 months) follow-up was available, 12 had complete relief of symptoms with no need for medications and full return to all activities. The patient who had the largest lesion of the study required surgical intervention because of collapse of the articular surface in the treatment area. Residual viable tumor was found at surgery. Another patient experienced mechanical problems that were thought to be unrelated to the RF ablation and was rendered pain-free after subsequent surgical treatment.
Conclusion: Percutaneous RF ablation is an alternative to surgery for treatment of selected chondroblastomas. Larger lesions beneath weight-bearing surfaces should be approached with caution due to an increased risk of articular collapse and recurrence.

AB Background: Previously, we reported abnormal volume and global shape in the caudate nucleus in schizotypal personality disorder (SPD). Here, we use a new shape measure which importantly permits local in addition to global shape analysis, as well as local correlations with behavioral measures.
Methods: Thirty-two female and 15 male SPDs, and 29 female and 14 male normal controls (NCLs), underwent brain magnetic resonance imaging (MRI). We assessed caudate shape measures using spherical harmonic-point distribution model (SPHARM-PDM) methodology.
Results: We found more pronounced global shape differences in the right caudate in male and female SPD, compared with NCLs. Local shape differences, principally in the caudate head, survived statistical correction on the right. Also, we performed correlations between local surface deformations with clinical measures and found significant correlations between local shape deflated deformations in the anterior medial surface of the caudate with verbal learning capacity in female SPD.
Conclusions: Using SPHARM-PDM methodology, we found both global and local caudate shape abnormalities in male and female SPD, particularly right-sided, and largely restricted to limbic and cognitive anterior caudate. The most important and novel findings were bilateral statistically significant correlations between local surface deflations in the anterior medial surface of the head of the caudate and verbal learning capacity in female SPD. By extension, these local caudate correlation findings implicate the ventromedial prefrontal cortex (vmPFC), which innervates that area of the caudate, and demonstrate the utility of local shape analysis to investigate the relationship between specific subcortical and cortical brain structures in neuropsychiatric conditions.

AB Background: The goal of the study was to examine mismatch negativity (MMN) in schizotypal personality disorder (SPD) individuals. Abnormal MMN has been a consistent finding in chronic schizophrenia and there also have been reports of reduced duration MMN in first episode schizophrenia patients [Umbricht, D., Krljes, S., Mismatch negativity in schizophrenia: a meta-analysis. Schizophrenia Research (2005); 76(1):1-23], with some studies finding no pitch MMN amplitude differences [Salisbury, D.F., Shenton, M.E., Griggs, C.B., Bonner-Jackson, A., McCarley, R.W., Mismatch negativity in chronic schizophrenia and first-episode schizophrenia. Archives of General Psychiatry (2002); 59(8):686-694.], while others reporting a modest reduction [Umbricht, D.S., Bates, J.A., Lieberman, J.A., Kane, J.M., Javitt, D.C., Electrophysiological indices of automatic and controlled auditory information processing in first-episode, recent-onset and chronic schizophrenia. Biological Psychiatry (2006); 59(8):762-772], in recent onset schizophrenia patients. To our knowledge no reports exist of MMN in SPD individuals.
Methods: Twenty six normal (14 females) control and 23 SPD (12 females) individuals were tested using the pitch MMN paradigm. Normal control (NC) and SPD individuals were recruited from the general population and assessed using DSM-IV. SPD individuals were included if they met 5 or more criteria for SPD disorder. The subjects listened to 2000 frequent 1 kHz pure tones and 100 rare 1.2 kHz pure tones while reading a magazine article. MMN was measured from a difference waveform within the latency window of 175-276 ms.
Results: Reduced MMN amplitude was found in SPD relative to NC subjects (p < 0.045).
Conclusions: These results point to potential differences between SPD and schizophrenia, where no reduction in MMN was found in most studies of first episode patients. Published by Elsevier B.V.

AB Molecular preservation in non-avian dinosaurs is controversial. We present multiple lines of evidence that endogenous proteinaceous material is preserved in bone fragments and soft tissues from an 80-million-year-old Campanian hadrosaur, Brachylophosaurus canadensis [Museum of the Rockies (MOR) 2598]. Microstructural and immunological data are consistent with preservation of multiple bone matrix and vessel proteins, and phylogenetic analyses of Brachylophosaurus collagen sequenced by mass spectrometry robustly support the bird-dinosaur clade, consistent with an endogenous source for these collagen peptides. These data complement earlier results from Tyrannosaurus rex (MOR 1125) and confirm that molecular preservation in Cretaceous dinosaurs is not a unique event.

AB The gamma-secretase complex plays a role in Alzheimer's disease and cancer progression. The development of clinically useful inhibitors, however, is complicated by the role of the gamma-secretase complex in regulated intramembrane proteolysis of Notch and other essential proteins. Different gamma-secretase complexes containing different Presenilin or Aph1 protein subunits are present in various tissues. Here we show that these complexes have heterogeneous biochemical and physiological properties. Specific inactivation of the Aph1B gamma-secretase in a mouse Alzheimer's disease model led to improvements of Alzheimer's disease-relevant phenotypic features without any Notch-related side effects. The Aph1B complex contributes to total gamma-secretase activity in the human brain, and thus specific targeting of Aph1B-containing gamma-secretase complexes may help generate less toxic therapies for Alzheimer's disease.

AB Influenza A virus nucleoprotein (NP) forms homo-oligomers and multiple copies of NP wrap around genomic RNA, along with a trimeric polymerase making up ribonucleoprotein (RNP) complex. Sequence comparison of more than 2500 influenza A NP showed that this protein contains 30.1 % of polymorphic residues. NP is composed of a head and a body domain and a tail loop/ linker region. The head domain is more conserved than the body domain, as revealed from the structure-based sequence alignment. NP oligomerization is mediated by the insertion of the non-polymorphic and structurally conserved tail loop of one NP molecule to a groove of another NP. The different form of NP oligomers is due to the flexibility of the polymorphic linkers that join the tail loop to the rest of the protein. The RNA binding property of NP is known to involve the protruding element and the flexible basic loop between the head and body domains, both having high degree of primary sequence conservation. To bind RNA, NP may first capture the RNA by the flexible basic loop and then the RNA is clamped by the protruding element.

AB Despite documented widespread human exposure to polybrominated diphenyl ethers (PBDEs) through dietary intake and contact with or inhalation of indoor dust, along with growing laboratory evidence for altered endocrine function following exposure, human Studies of PBDE exposure and endocrine effects remain limited. We conducted a preliminary study within an ongoing study on the impact of environmental exposures on male reproductive health. We measured serum hormone levels and PBDE concentrations (BDE 47, 99 and 100) in house dust from 24 men recruited through a US infertility clinic. BDE 47 and 99 were detected in 100% of dust samples, and BDE 100 was detected in 67% of dust samples, at concentrations similar to those reported in previous US studies. In multivariable regression models adjusted for age and BMI, there was a statistically significant inverse relationship between dust PBDE concentrations and free androgen index. Dust PBDE concentrations were also strongly and inversely associated with luteinizing hormone (LH) and follicle stimulating hormone (FSH), and positively associated with inhibin B and sex hormone binding globulin (SHBG). Finally, consistent with limited recent human studies of adults, PBDEs were positively associated with free T4. In conclusion, the present study provides compelling evidence of altered hormone levels in relation to PBDE exposures estimated as concentrations in house dust, and that house dust is an important source of human PBDE exposure, but more research is urgently needed.

AB Abnormalities in thirst and vasopressin (AVP) release play key roles in the genesis of hyponatremia; both processes are under the control of osmoreceptive neurons in the central nervous system (CNS). The acute development of hyponatremia ill turn leads to profound cerebral edema, whereas treatment of chronic hyponatremia call be associated with osmotic demyelination syndrome (ODS). The brain is thus both "culprit" and "victim" in hyponatremia. This review Summarizes recent advances in the understanding of osmoreception in the brain, the CNS response to acute and chronic hyponatremia, and the pathophysiology of ODS.

AB Study Design: Cross-sectional study.
Objectives: The purpose of this study was to examine stroke characteristics of long-term manual wheelchair users during an extended manual wheelchair propulsion trial and the extent to which changes in propulsion biomechanics occurred.
Setting: Human Engineering Research Laboratories, VA Rehabilitation Research and Development Center, VA Pittsburgh Healthcare Systems, Pittsburgh, PA, USA.
Methods: Kinetic data were recorded from 21 subjects with paraplegia at four time points over the course of a 10-min propulsion trial at a steady state speed of 1.4 ms(-1). Upper extremity kinetic parameters were recorded using Smartwheels, force and torque sensing pushrims.
Results: Subjects for propulsion biomechanics changed from early to late during the 10-min trial. Individuals displayed decreased maximum rate of rise of resultant force (P=0.0045) with a simultaneous increase in push time (P=0.043) and stroke time (P=0.023), whereas stroke frequency remained static. In addition, there was a decrease in out of plane moment application (P=0.032).
Conclusion: Individuals seemed to naturally accommodate their propulsive stroke, using less injurious propulsion biomechanics over the course of a 10-minute trial on a dynamometer. The findings may have occurred as a result of both biomechanical compensations to a challenging propulsion trial and accommodation to propelling on a dynamometer. These results suggest that subjects may be capable of independently incorporating favorable biomechanical strategies to meet the demands of a challenging propulsion scenario.

AB Study Design. Clinical practice guideline. Objective. To develop evidence-based recommendations on use of interventional diagnostic tests and therapies, surgeries, and interdisciplinary rehabilitation for low back pain of any duration, with or without leg pain.
Summary of Background Data. Management of patients with persistent and disabling low back pain remains a clinical challenge. A number of interventional diagnostic tests and therapies and surgery are available and their use is increasing, but in some cases their utility remains uncertain or controversial. Interdisciplinary rehabilitation has also been proposed as a potentially effective noninvasive intervention for persistent and disabling low back pain.
Methods. A multidisciplinary panel was convened by the American Pain Society. Its recommendations were based on a systematic review that focused on evidence from randomized controlled trials. Recommendations were graded using methods adapted from the US Preventive Services Task Force and the Grading of Recommendations, Assessment, Development, and Evaluation Working Group.
Results. Investigators reviewed 3348 abstracts. A total of 161 randomized trials were deemed relevant to the recommendations in this guideline. The panel developed a total of 8 recommendations.
Conclusion. Recommendations on use of interventional diagnostic tests and therapies, surgery, and interdisciplinary rehabilitation are presented. Due to important trade-offs between potential benefits, harms, costs, and burdens of alternative therapies, shared decision-making is an important component of a number of the recommendations.

AB Background and Purpose-Hyperglycemia strongly predicts poor outcome in patients with aneurysmal subarachnoid hemorrhage, but the effect of hyperglycemia management on outcome is unclear. We studied the impact of glycemic control on outcome of patients with aneurysmal subarachnoid hemorrhage.
Methods-A prospective intensive care unit database was used to identify 332 patients with hyperglycemic aneurysmal subarachnoid hemorrhage admitted between January 2000 and December 2006. Patients treated with an aggressive hyperglycemia management (AHM) protocol after 2003 (N = 166) were compared with 166 patients treated using a standard hyperglycemia management before 2003. Within the AHM group, outcome was compared between patients who achieved good (mean glucose burden <1.1 mmol/L) and poor (mean glucose burden <1.1 mmol/L) glycemic control. Poor outcome was defined as modified Rankin scale >= 4 at 3 to 6 months. Multivariable logistic regression models correcting for temporal trend were used to quantify the effect of AHM on poor outcome.
Results-Poor outcome in AHM-treated patients was lower (28.31% versus 40.36%) but was not statistically significant after correcting for temporal trend. However, good glycemic control significantly reduced the incidence of poor outcome (OR, 0.25; 95% CI, 0.08 to 0.80; P=0.02) compared with patients with poor glycemic control within the AHM group. No difference in the rate of clinical vasospasm or the development of delayed ischemic neurological deficit was seen before and after AHM protocol implementation.
Conclusion-AHM results in good glucose control and significantly reduces the odds for poor outcome after aneurysmal subarachnoid hemorrhage in glucose-controlled patients. Further studies are needed to confirm these results. (Stroke. 2009; 40: 1644-1652.)

AB Background and Purpose-Better selection of patients for intravenous recombinant tissue plasminogen activator (IV tPA) treatment may improve clinical outcomes. We examined the cost-effectiveness of adding penumbral-based MRI to usual computed tomography (CT)-based methods to identify patients for IV tPA treatment.
Methods-A decision-analytic model estimated the lifetime costs and outcomes associated with penumbral-based MRI selection in a patient population similar to that enrolled in the IV tPA clinical trials. Inputs were obtained from published literature, clinical trial data, claims databases, and expert opinion. Outcomes included cost per life-year saved and cost per quality-adjusted life-year (QALY) gained. Costs and outcomes were discounted at 3% annually. Sensitivity analyses were conducted.
Results-The addition of penumbral-based MRI selection increased total cost by $103 over the patient's remaining lifetime. Penumbral-based MRI selection resulted in favorable outcomes (modified Rankin Scale <= 1) more often than CT-based selection (36.66% versus 35.06%) with an incremental cost per life year of $1840 and an incremental cost per QALY of $1004. Multivariate sensitivity analysis predicted cost-effectiveness (<=$50 000 per QALY) in 99.7% of simulation runs.
Conclusions-Selecting ischemic stroke patients for IV tPA treatment using penumbral-based MRI after routine CT may increase overall acute care costs, but the benefit is large enough to make this highly cost-effective. This economic analysis lends further support to the consideration of a paradigm shift in acute stroke evaluation. (Stroke. 2009; 40: 1710-1720.)

Methods-An annual summit was first held in 2006, bringing together public health officials, researchers, physicians, nurses, health professionals, state legislators, and advocacy organizations. Best practices and evidence-based interventions within each of the Stroke Systems of Care Model components were presented. Six writing groups were tasked with cataloging each state's current activities and identifying goals for the region.
Results-There were significant variations in the delivery of stroke care, particularly in urban versus rural areas, as evidenced by the availability of designated stroke centers and neurologists, and stroke-related death rates. Recommendations to address variations in care delivery included the use of a common stroke data collection system, unified community education criteria, improvements to emergency medical services dispatch and training, adoption of prehospital care measures, creation of a web-based central repository of acute stroke protocols and order sets, a regional atlas of stroke resources and capabilities, a stroke patient "report card" to promote adherence to secondary prevention strategies, and explicit standards for rehabilitation services.
Conclusions-Significant disparities in the delivery of stroke care across the 8 state-region have been identified. Northeast Cerebrovascular Consortium demonstrates that multistate regional collaboration is a viable process for developing specific regional recommendations to address those disparities. Northeast Cerebrovascular Consortium is assessing the usefulness of the Stroke Systems of Care Model as a framework for implementing a regional approach to stroke across the continuum of care.

AB Background and Purpose-The purpose of this study was to examine whether there are disparities in use of stroke secondary prevention services because disparities in stroke outcomes have been found among older adults, women, racial minorities, and within Stroke Belt states.
Methods-Using the nationally-representative 2005 Behavior Risk Factor Surveillance System, we examined self-reported use of 11 stroke secondary prevention services queried in the survey. We used multivariable logistic regression to examine the association between service use and age, sex, race, and Stroke Belt state residence, controlling for other socio-demographic and health care access characteristics.
Results-Among 11 862 adults with a history of stroke, 16% were 80 or older, 54% were women, 13% were non-Hispanic black, and 23% lived within a Stroke Belt state. Overall service use varied: 31% reported poststroke outpatient rehabilitation, 57% regular exercise, 66% smoking cessation counseling, and 91% current use of antihypertensive medications. Age 80 or older was not associated with lower use of any of the 11 services. Women were less likely to report poststroke outpatient rehabilitation and regular exercise when compared with men (probability values <= 0.005); there were no sex-based differences in use of the 9 other services. Blacks were less likely to report pneumococcal vaccination when compared with whites, but were more likely to report poststroke outpatient rehabilitation (probability values <= 0.005); there were no race-based differences in use of the 9 other services. Stroke Belt state residence was not associated with lower use of any of the 11 services.
Conclusions-Use of many stroke secondary prevention services was suboptimal. We did not find consistent age, sex, racial, or Stroke Belt state residence disparities in care. (Stroke. 2009; 40: 1811-1819.)

TI Arterial Wall Enhancement Overlying Carotid Plaque on CT Angiography
Correlates With Symptoms in Patients With High Grade Stenosis

ID COMPUTED-TOMOGRAPHY; VASA VASORUM; ATHEROSCLEROSIS
AB Background and Purpose-The degree of internal carotid artery (ICA) stenosis is an established primary risk factor for embolic stroke. Recent publications suggest that inflammatory features may also play an important role. Our purpose was to correlate acute neurological symptoms with either carotid artery wall enhancement or plaque calcification, on axial CT angiographic source images (CTA-SI) of patients with severe (>= 70%) ICA stenosis.
Methods-75 consecutive patients with >= 70% ICA stenosis on CTA-SI were identified. Each case was classified as symptomatic (n=37) or asymptomatic (n=38), and as having either calcified or noncalcified plaque. The latter group was stratified into those with versus without arterial wall enhancement, measured in absolute and relative Hounsfield Units (HU).
Results-Calcified plaque was present in 39% (15/38) of the symptomatic patients and in 62% (23/37) of the asymptomatic patients (P=0.065). Of the 37 patients without calcified plaque, carotid wall enhancement was observed in 83% (19/23) of the symptomatic, but only in 57% (8/14) of the asymptomatic patients (P=0.041). When the "calcified plaque" and "no carotid wall enhancement" groups were pooled, versus the "carotid wall enhancement" group, enhancement was more likely in symptomatic patients (OR 3.625, CI 95% 1.3229 to 9.93, P=0.01 Fisher Exact test).
Conclusions-In patients with severe ICA stenosis, additional stratification of stroke risk may be possible based on the presence of carotid wall enhancement on CTA-SI. Patients with carotid wall enhancement are more likely to be symptomatic, compared to those with either calcified plaque or no enhancement. (Stroke. 2009; 40: 1894-1896.)

LA English
DT Article
ID FOREIGN-BODIES; PATIENT SAFETY; OPERATING-ROOM; SURGERY; INSTRUMENTS;
TECHNOLOGY; IMPACT
AB Background. New technologies are available to reduce or prevent retained surgical sponges (RSS), but their relative cost effectiveness are unknown. We developed an empirically calibrated decision-analytic model comparing standard. counting against alternative strategies: universal or selective x-ray, bar-coded sponges (BCS), and radiofrequency-tagged (RF) sponges.
Methods. Key model parameters were obtained front field observations during a randomized-controlled BCS trial (n = 298), an observational study of RSS (n = 191,168), and clinical experience with BCS (n similar to 60,000). Because no comparable data exist for RF, we modeled its performance under 2 alternative assumptions. Only incremental sponge tracking costs, excluding those common to all strategies, were considered. Main outcomes were RSS incidence and cost-effectiveness ratios for each strategy, front the institutional decision maker's perspective.
Results. Standard counting detects 82% of RSS. Bar coding prevents >= 97.5% for an additional $95,000 per RSS averted. If RF were as effective as bar coding, it would cost $720,000 per additional RSS averted (versus standard counting). Universal and selective x-rays for high-risk operations are more costly, but less effective than BCS-$1.1 to 1.4 million per RSS event prevented. In sensitivity analyses, results were robust over the plausible range of effectiveness assumptions, but sensitive to cost.
Conclusion. Using currently available data, this analysis provides a useful model for comparing the relative cost effectiveness of existing sponge tracking strategies. Selecting the best method for an institution depends on its priorities: ease of use, cost reduction., or ensuring RSS are truly "never events." Given medical and liability costs of >$200,000 per incident, novel technologies can substantially reduce the incidence of RSS at an acceptable cost. (Surgery 2009;145:527-35.)

AB Asenapine, a new pyschopharmacologic agent being developed for the treatment of schizophrenia and bipolar disorder, has a unique human receptor binding signature with strong affinity for dopaminergic, alpha-adrenergic, and, in particular, serotonergic receptors raising the possibility of interactions with glutamatergic receptors. Changes in ionotropic glutamate (Glu) N-methyl-D-aspartic acid (NMDA) receptors and 2-amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl)propionic acid (AMPA) receptors in rat forebrain regions were quantified after repeated administration of multiple doses of asenapine (0.03, 0.1, or 0.3 mg/kg, subcutaneous, twice/day) or vehicle for 4 weeks. Brain sections were collected from the medial prefrontal cortex (mPFC), dorsolateral frontal cortex, caudate putamen (CPu), nucleus accumbens (NAc), and hippocampus (HIP), and processed for in vitro receptor autoradiography. Four weeks of treatment with 0.03, 0.1, or 0.3 mg/kg of asenapine significantly (P < 0.01) decreased binding of [(3)H]MK-801 to NMDA/MK-801 modulatory sites in NAc (by 27%, 29%, and 26%, respectively), medial CPu (by 25%, 28%, and 24%), and lateral CPu (by 24%, 31%, and 26%). In contrast, the same doses of asenapine did not alter binding of [(3)H]glycine to NMDA/glycine modulatory sites in any of the brain regions examined. [(3)H]AMPA binding to AMPA receptors was selectively and significantly (P < 0.001) elevated in hippocampal CA(1) (41%) and CA(3) (40%) regions but only at the highest dose tested. These results indicate that chronic treatment with asenapine has region-specific and dose-dependent effects on ionotropic Glu-receptor subtypes in rat forebrain, which might contribute to the unique psychopharmacologic properties of asenapine.

AB This study investigates the feasibility and effectiveness of providing telepsychiatry services to Chinese immigrants in a nursing home. The psychiatrist interviewed patients face-to-face for the initial consultation, and encouraged them to participate in this study to receive telepsychiatry-based follow-up visits. The feasibility and outcomes of telepsychiatry visits and satisfaction of the subjects, their families, and the nursing home staff were assessed. Nine monolingual Chinese immigrants, 8 women and 1 man, ranging from 54 to 88 years of age, were enrolled. The main reasons for psychiatric consultation were mood and behavioral problems. Eight of the 9 (88.9%) subjects participated in videoconference follow-up visits, and 1 subject (11.1%) declined. Among the 8 subjects, 6 were referred for psychiatric intervention, 1 for differential diagnosis, and 1 for suicide assessment. At the end of the study, all 6 subjects referred for intervention had greatly improved; the subjects, their families, and the nursing staff were highly satisfied with the telepsychiatry service. It is feasible to provide psychiatry consultations to ethnic immigrants in a nursing home despite the fact that many of them are unfamiliar with the technology and suffer from dementia and psychotic symptoms. Telepsychiatry provides an efficient way for ethnic elders in nursing homes to connect with mental health professionals with the appropriate language and cultural background, regardless of location. Telepsychiatry may decrease the disparities in treatment of mental illnesses among ethnic immigrants in nursing homes.

AB Amniotic fluid (AF) may induce disseminated intravascular coagulation (DIC) when it enters maternal circulation by breaching the placental-maternal circulation barrier. The precise mechanism of the procoagulant activity of AF is unclear, but tissue factor (TF) has been proposed to be the main cause. As one constituent of AF, AF cells accumulate and undergo apoptosis continuously. Therefore, we speculate that AF cells have procoagulant activity due to the externalisation of phosphatidylserine (PS). The present study aims to demonstrate that, in addition to TF, the PS that is externalised on AF cells is important for the procoagulant activity of AF. Ten AF samples from parturient women were analysed using lactadherin as the probe for PS. Anti-TF antibody also was used to identify TF and its associated coagulation functions in AF cells. Normal platelets, neutrophils, and lymphocytes were harvested as controls. Confocal microscopy and flow cytometry was used to assess PS expression on AF cells. The procoagulant activity of AF cells was demonstrated by a plasma coagulation assay and further confirmed by factor Xase/prothrombinase assays. PS and TF were present on most AF cells, providing substantial procoagulant activity. Furthermore, factor Xase and prothrombinase assays showed that AF cells substantially enforced the activation of factor X and prothrombin. PS on AF cells is an important procoagulant source for AF. Lactadherin is an ideal anticoagulant for inhibiting the procoagulant activity of AF cells.

AB Double-cord-blood transplantation (DCBT) offers an option for patients receiving reduced-intensity transplants. These unique transplants have two donors, both of whom are usually HLA mismatched at one to two loci.
Fifty-three patients were recipients of a reduced-intensity DCBT. Cords were at least 4/6 allele-level HLA-A, -B, and -DR match with the patient and each other with a minimum combined cell dose of more than 3.7 x 10(7) total nucleated cells per kg. Twenty-one patients received cyclosporine/mycophenolate mofetil and 32 patients received sirolimus/tacrolimus (SIR/TAC) for graft-versus-host disease prophylaxis. The effect of allele level HLA typing on clinical endpoints of overall survival (OS), disease-free survival (DFS), engraftment, and acute graft-versus-host disease (aGVHD) were assessed.
Neutrophil (p = 0.001) engraftment and platelet engraftment (p = 0.027) were significantly faster in patients who have closer Class I (HLA-A, -B, -C) matching. Neutrophil engraftment was faster in patients who had closer HLA-B matching to their combined cords (p = 0.007). There was a low incidence of aGVHD overall, especially in the SIR/TAC group. Class I HLA matching had no effect on aGVHD. HLA-DR and -DQ had no effect on engraftment or aGVHD.
Class I allele matching, and HLA-B matching specifically, were associated with faster neutrophil engraftment. High-resolution HLA matching did not affect OS or DFS.

AB Recent studies highlight the importance of the distribution of membrane receptors in controlling receptor output and in contributing to complex biological processes. The cortical cytoskeleton is known to affect membrane protein distribution but the molecular basis of this is largely unknown. Here, we discuss the functions of Merlin and the ERM proteins both in linking membrane proteins to the underlying cortical cytoskeleton and in controlling the distribution of and signaling from membrane receptors. We also propose a model that could account for the intricacies of Merlin function across model organisms.

AB The gaseous plant hormone ethylene acts as a pivotal mediator to respond to and coordinate internal and external cues in modulating plant growth dynamics and developmental programs. Genetic analysis of Arabidopsis thaliana has been used to identify key components and to build a linear ethylene-signaling pathway from the receptors through to the nuclear transcription factors. Studies applying integrative approaches have revealed new regulators, molecular connections and mechanisms in ethylene signaling and unexpected links to other plant hormones. Here, we review and discuss recent discoveries about the functional mode of ethylene receptor complexes, dual mitogen-activated protein kinase cascade signaling, stability control of the master nuclear transcription activator ETHYLENE INSENSITIVE 3 (EIN3), and the contextual relationships between ethylene and other plant hormones, such as auxin and gibberellins, in organ-specific growth regulation.

AB Recently, advances in imaging technology have made possible the ability to image noninvasively specific molecular pathways in vivo that are involved in disease processes. Molecular imaging evaluates changes in cellular physiology and function rather than anatomy, which are likely to be earlier and more sensitive manifestations of disease. In addition, as newer drugs to treat disease become increasingly molecule specific, molecular imaging has become necessary to provide noninvasive determination of patients likely to benefit from treatment and early therapy response. This article reviews current and emerging molecular imaging technologies relevant to urologic surgery.

AB OBJECTIVES: To determine whether an association exists between C reactive protein (CRP) levels and lower urinary tract symptoms (LUTS) as assessed by the American Urological Association Symptom Index (AUA-SI) among both men and women, and to determine the association of CRP levels with the individual urologic symptoms comprising the AUA-SI among both men and women.
METHODS: The Boston Area Community Health survey used a multistage stratified design to recruit a random sample of 5502 adults aged 30-79 years. Blood samples were obtained from 3752 participants. The analyses were conducted on 1898 men and 1854 women with complete data on CRP levels. Overall LUTS was defined as an AUA-SI of >= 8 (moderate to severe LUTS). The urologic symptoms comprising the AUA-SI were included in the analysis as reports of fairly often to almost always vs non/rarely/a few times.
RESULTS: A statistically significant association was observed between the CRP levels and overall LUTS among both men and women. The pattern of associations between the individual symptoms and CRP levels varied by sex. Nocturia and straining were associated with greater CRP levels among men, and incomplete emptying and weak stream were associated with greater CRP levels among women.
CONCLUSIONS: The results of this study have demonstrated an association between CRP levels and LUTS in both men and women. The dose-response relationship between increased CRP levels and an increased odds of LUTS supports the hypothesized role of inflammatory processes in the etiology of LUTS. UROLOGY 73: 950-957, 2009.

AB Bilirubin may have a major role in the prevention of cardiovascular disease based on recent data regarding its anti-oxidant properties. We determined the relationship between total serum bilirubin and vascular reactivity in a large cohort of individuals with diabetes, a disease associated with known oxidant stress. We studied 302 individuals: 52 controls, 37 with type 1 diabetes, 213 with type 2 diabetes. High-resolution ultrasound was used to measure flow-mediated dilation (FMD; endotheliumdependent) and nitroglycerin-induced dilation (NID, endothelium-independent) of the brachial artery. Laser Doppler perfusion imaging was used to measure microvascular reactivity in the forearm skin before and after iontophoresis of acetylcholine (endothelium-dependent) and sodium nitroprusside (endothelium- independent). Bilirubin levels were higher in the type 2 diabetes group (0.71 +/- 0.34 mg/dl) compared to controls (0.56 +/- 0.26 mg/dl, p < 0.0001). A weak inverse correlation was observed between bilirubin and FMD (r = -0.125, p = 0.032) and skin endothelium- dependent vasodilation (r = -0.157, p = 0.019). In multivariate analyses, however, these correlations were not statistically significant. There is no association between bilirubin levels and vascular reactivity in the macro- and microcirculation of individuals with diabetes. Bilirubin, therefore, does not correlate with predictors of cardiovascular risk in the diabetic population.

AB Digital thermal monitoring (DTM) of vascular function during cuff-occlusive reactive hyperemia relies on the premise that changes in fingertip temperature during and after an ischemic stimulus reflect changes in blood flow. To determine its utility in individuals with and without known coronary heart disease (CHD), 133 consecutive individuals (age 54 +/- 10 years, 50% male, 19 with known CHD) underwent DTM during and after 2 minutes of supra-systolic arm cuff inflation. Fingertip temperatures of the occluded and non-occluded fingertips were measured simultaneously. Post-cuff deflation temperature rebound (TR) was lower in the CHD patients and in those with an increased Framingham risk score (FRS) compared to the normal group. After adjustment for age, sex, and cardiac risk factors, TR was significantly lower in those with CHD compared to those without CHD (p < 0.05). This study demonstrates that vascular dysfunction measured by DTM is associated with CHD and an increased FRS, and could potentially be used to identify high-risk patients.

AB Vision begins with photoisomerization of 11-cis retinal to the all-trans conformation within the chromophore-binding pocket of opsin, leading to activation of a biochemical cascade. Release of all-trans retinal from the binding pocket curtails but does not fully quench file ability of opsin to activate transducin. All-trans retinal and some other analogs, Such as beta-ionone, enhance opsin's activity, presumably oil binding the empty chromophore-binding pocket. By recording from isolated salamander photoreceptors and from patches of rod outer segment membrane, we now show that high concentrations of beta-ionone suppressed circulating current in dark-adapted green-sensitive rods by inhibiting the cyclic nucleotide-gated channels. There were also decreases in circulating current and flash sensitivity, and accelerated flash response kinetics in dark-adapted blue-sensitive (BS) rods and cones. and in Ultraviolet-sensitive cones, at concentrations too low to inhibit the channels. These effects persisted in BS rods even after incubation with 9-cis retinal to ensure complete regeneration of their visual pigment, After long exposures to high concentrations of beta-ionone. recovery was incomplete unless 9-cis retinal was given, indicating that visual pigment had been bleached. Therefore, we propose that beta-ionone activates and bleaches some types of visual pigments, mimicking the effects of light.

AB Purpose. The objective of this study was to compare gender differences in mental health disease burden and outpatient mental health utilization among veterans utilizing Veterans Health Administration (VHA) mental health services in fiscal year 1999 (FY99), after the first Gulf War and significant restructuring of VHA services.
Methods. We used logistic regression to examine the relationships among gender, age, diagnostic groups, and utilization of mental health and specialty mental health services in a national sample of veterans. The sample included 782,789 veterans with at least 1 outpatient visit in the VHA in FY99 associated with a mental health or substance abuse (SA) diagnosis. Subgroup analyses were performed for 4 diagnostic categories: 1) posttraumatic stress disorder (PTSD), 2) SA disorders, 3) bipolar and psychotic disorders, and 4) mood and anxiety disorders.
Main Findings. Younger women veterans (<35 years old) were significantly less likely and older women (>= 35) more likely to use any mental health services in comparison with their male counterparts. Similar findings were observed for younger women diagnosed with SA or mood and anxiety disorders, but not among veterans with PTSD or bipolar and psychotic disorders, among whom no there were no gender or age differences. In the case of specialized services for SA or PTSD, women younger than 55 with SA or PTSD were significantly less likely to use services than men.
Conclusion. Women veterans underutilized specialty mental health services in relation to men but receipt of mental health care overall in FY99 varied by age and diagnosis. Examining gender differences alone, without taking other factors into account, may not provide an adequate picture of women veterans' current mental health service needs.

AB Recently, many new drugs have been developed for the treatment of Waldenstrom macroglobulinemia (WM). To optimize the treatment according to the prognosis and to facilitate the comparison of trials, we developed an International Prognostic Scoring System for WM in a series of 587 patients with clearly defined criteria for diagnosis and for initiation of treatment. The median survival after treatment initiation was 87 months. Five adverse covariates were identified: advanced age (> 65 years), hemoglobin less than or equal to 11.5 g/dL, platelet count less than or equal to 100 x 10(9)/L, beta 2-microglobulin more than 3 mg/L, and serum monoclonal protein concentration more than 7.0 g/dL. Low-risk patients (27%) presented with no or 1 of the adverse characteristics and advanced age, intermediate-risk patients (38%) with 2 adverse characteristics or only advanced age, and high-risk patients (35%) with more than 2 adverse characteristics. Five-year survival rates were 87%, 68%, and 36%, respectively (P<.001). The ISSWM retained its prognostic significance in subgroups defined by age, treatment with alkylating agent, and purine analog. Thus, the ISSWM may provide a means to design risk-adapted studies. However, independent validation and new biologic markers may enhance its significance. (Blood. 2009; 113: 4163-4170)

AB The interaction of multiple myeloma (MM) cells with their microenvironment in the bone marrow (BM) provides a protective environment and resistance to therapeutic agents. We hypothesized that disruption of the interaction of MM cells with their BM milieu would lead to their sensitization to therapeutic agents such as bortezomib, melphalan, doxorubicin, and dexamethasone. We report that the CXCR4 inhibitor AMD3100 induces disruption of the interaction of MM cells with the BM reflected by mobilization of MM cells into the circulation in vivo, with kinetics that differed from that of hematopoietic stem cells. AMD3100 enhanced sensitivity of MM cell to multiple therapeutic agents in vitro by disrupting adhesion of MM cells to bone marrow stromal cells (BMSCs). Moreover, AMD3100 increased mobilization of MM cells to the circulation in vivo, increased the ratio of apoptotic circulating MM cells, and enhanced the tumor reduction induced by bortezomib. Mechanistically, AMD3100 significantly inhibited Akt phosphorylation and enhanced poly(ADP-ribose) polymerase (PARP) cleavage as a result of bortezomib, in the presence of BMSCs in coculture. These experiments provide a proof of concept for the use of agents that disrupt interaction with the microenvironment for enhancement of efficacy of cytotoxic agents in cancer therapy.

AB Multilevel genetic characterization of Waldenstrom macroglobulinemia (WM) is required to improve our understanding of the underlying molecular changes that lead to the initiation and progression of this disease. We performed microRNA-expression profiling of bone marrow-derived CD19(+) WM cells, compared with their normal cellular counterparts and validated data by quantitative reverse-transcription-polymerase chain reaction (qRT-PCR). We identified a WM-specific microRNA signature characterized by increased expression of microRNA-363*/-206/-494/-155/-184/-542-3p, and decreased expression of microRNA-9* (ANOVA; P < .01). We found that microRNA-155 regulates proliferation and growth of WM cells in vitro and in vivo, by inhibiting MAPK/ERK, PI3/AKT, and NF-kappa B pathways. Potential microRNA-155 target genes were identified using gene-expression profiling and included genes involved in cell-cycle progression, adhesion, and migration. Importantly, increased expression of the 6 miRNAs significantly correlated with a poorer outcome predicted by the International Prognostic Staging System for WM. We further demonstrated that therapeutic agents commonly used in WM alter the levels of the major miRNAs identified, by inducing downmodulation of 5 increased miRNAs and up-modulation of patient-downexpressed miRNA-9*. These data indicate that microRNAs play a pivotal role in the biology of WM; represent important prognostic marker; and provide the basis for the development of new microRNA-based targeted therapies in WM.

AB The involvement of the cervical sympathetic ganglia (SCG) on body temperature and during the occurrence of the induced febrile response was investigated in rats. Bilateral superior cervical gaglionectomy (SCGx) attenuated the daily dark-phase temperature compared to that of the sham-operated rats during the first 2 days post surgery. Body temperatures returned to pre-surgery levels by Day-3. Ten days after surgery, a febrile response was induced by lipopolysaccharide (LPS) immune challenge. SCGx significantly blunted the LPS-induced febrile response. These data suggest that obliteration of the cervical sympathetic peripheral innervation impairs the capability to produce an induced febrile response. (C) 2009 Elsevier B.V. All rights reserved.

AB The difficulty of visual recognition stems from the need to achieve high selectivity while maintaining robustness to object transformations within hundreds of milliseconds. Theories of visual recognition differ in whether the neuronal circuits invoke recurrent feedback connections or not. The timing of neurophysiological responses in visual cortex plays a key role in distinguishing between bottom-up and top-down theories. Here, we quantified at millisecond resolution the amount of visual information conveyed by intracranial field potentials from 912 electrodes in 11 human subjects. We could decode object category information from human visual cortex in single trials as early as 100 ms poststimulus. Decoding performance was robust to depth rotation and scale changes. The results suggest that physiological activity in the temporal lobe can account for key properties of visual recognition. The fast decoding in single trials is compatible with feedforward theories and provides strong constraints for computational models of human vision.

AB Purpose: A growing body of research supports an important role for GABA in the pathophysiology of bipolar and other mood disorders. The purpose of the current study was to directly examine brain GABA levels in a clinical sample of bipolar patients.
General methods: We used magnetic resonance spectroscopy (MRS) to examine whole brain and regional GABA, glutamate and glutamine in 13 patients with bipolar disorder compared to a matched group of 11 healthy controls.
Findings: There were no significant differences in GABA, glutamate or glutamine between patients and controls.
Conclusions: Further research is needed to better characterize the GABAergic and glutamatergic effects of pharmacotherapy, anxiety comorbidity and clinical state in bipolar disorder. (C) 2009 Elsevier Inc. All rights reserved.

SO STATISTICS IN MEDICINE

ID MULTIPLE-SCLEROSIS; PROGRESSION; DISABILITY; TIME
AB In many diseases, Markov transition models are useful in describing transitions between discrete disease states. Often the probability of transitioning from one state to another varies widely across subjects. This heterogeneity is driven, in part, by a possibly unknown number of previous disease states and by potentially complex relationships between clinical data and these states. We propose use of Bayesian variable selection in Markov transition models to allow estimation of subject-specific transition probabilities. Our approach simultaneously estimates the order of the Markov process and the transition-specific covariate effects. The methods are assessed using Simulation studies and applied to model disease-state transition on the expanded disability status scale (EDSS) in multiple sclerosis (MS) patients from the Partners MS Center in Boston, MA. The proposed methodology is shown to accurately identify complex covariate-transition relationships in simulations and identifies a clinically significant interaction between relapse history and EDSS history in MS patients.

AB Tumour stroma gene expression in biopsy specimens may obscure the expression of tumour parenchyma, hampering the predictive power of microarrays. We aimed to assess the utility of fluorescence-activated cell sorting (FACS) for generating cell populations for gene expression analysis and to compare the gene expression of FACS-purified tumour parenchyma to that of whole tumour biopsies. Single cell suspensions were generated from colorectal tumour biopsies and tumour parenchyma was separated using FACS. Fluorescence-activated cell sorting allowed reliable estimation and purification of cell populations, generating parenchymal purity above 90%. RNA from FACS-purified and corresponding whole tumour biopsies was hybridised to Affymetrix oligonucleotide microarrays. Whole tumour and parenchymal samples demonstrated differential gene expression, with 289 genes significantly overexpressed in the whole tumour, many of which were consistent with stromal gene expression (e. g., COL6A3, COL1A2, POSTN, TIMP2). Genes characteristic of colorectal carcinoma were overexpressed in the FACS- purified cells (e. g., HOX2D and RHOB). We found FACS to be a robust method for generating samples for gene expression analysis, allowing simultaneous assessment of parenchymal and stromal compartments. Gross stromal contamination may affect the interpretation of cancer gene expression microarray experiments, with implications for hypotheses generation and the stability of expression signatures used for predicting clinical outcomes.

AB Cardiovascular magnetic resonance (CMR) has become the primary tool for noninvasive assessment of myocardial inflammation in patients with suspected myocarditis. The International Consensus Group on CMR Diagnosis of Myocarditis was founded in 2006 to achieve consensus among CMR experts and develop recommendations on the current state-of-the-art use of CMR for myocarditis. The recommendations include indications for CMR in patients with suspected myocarditis, CMR protocol standards, terminology for reporting CMR findings, and diagnostic CMR criteria for myocarditis (i.e., "Lake Louise Criteria").

AB Objectives We aimed to evaluate the efficacy and safety of ranolazine in a larger and more diverse group of patients with angina than previously studied.
Background Ranolazine is an antianginal shown to reduce angina and improve exercise performance in selected patients with early-positive exercise testing and those with frequent angina.
Methods We investigated the antianginal effects of ranolazine in the subgroup of patients with prior chronic angina (n = 3,565, 54%) enrolled in the randomized, double-blind, placebo-controlled MERLIN-TIMI (Metabolic Efficiency With Ranolazine for Less Ischemia in Non-ST Elevation Acute Coronary Syndromes) 36 trial of patients with acute coronary syndrome. Follow-up was a median of 350 days.
Results Patients with prior angina received evidence-based therapy (95% aspirin, 78% statins, 89% beta-blockers, average 2.9 antianginal agents). The primary end point (cardiovascular death, myocardial infarction, recurrent ischemia) was less frequent with ranolazine (hazard ratio [HR]: 0.86; 95% confidence interval [CI]: 0.75 to 0.97; p = 0.017), due entirely to a significant reduction in recurrent ischemia (HR: 0.78; 95% CI: 0.67 to 0.91; p = 0.002). Ranolazine also reduced worsening angina (HR: 0.77; 95% CI: 0.59 to 1.00; p = 0.048) and intensification of antianginal therapy (HR: 0.77; 95% CI: 0.64 to 0.92, p = 0.005). Exercise duration at 8 months was greater with ranolazine (514 s vs. 482 s, p = 0.002). Cardiovascular death or myocardial infarction did not differ between treatment groups (HR: 0.97; 95% CI: 0.80 to 1.16; p = 0.71). Symptomatic documented arrhythmias (2.9% vs. 2.9%, p = 0.92) and total mortality (6.2% vs. 6.4%, p = 0.96) were similar with ranolazine or placebo.
Conclusions In this largest study of ranolazine in patients with established coronary artery disease, ranolazine was effective in reducing angina with favorable safety in a substantially broader group of patients with angina than previously studied.

AB Objective: To determine if changes in brain metabolites are observed during early HIV infection and correlate these changes with immunologic alterations.
Methods: Eight subjects with early HIV infection, 9 HIV-seronegative controls, and 10 chronically HIV-infected subjects without neurologic impairment underwent (1)H magnetic resonance spectroscopy. Subjects with early stage infection were identified near the time of HIV seroconversion and imaged within 60 days of an evolving Western blot, while still having detectable plasma virus. Subjects had blood drawn for viral RNA and T cell quantification.
Results: Both N-acetylaspartate (NAA) and Glx (glutamate + glutamine) were decreased in the frontal cortical gray matter of seropositive subjects. NAA levels were found to be decreased in the centrum semiovale white matter of chronically HIV-infected subjects, but not in those with early infection. Both HIV-infected cohorts demonstrated a lower number of CD4(+) T lymphocytes and a higher number of CD8(+) T lymphocytes in their blood. Lower NAA levels in the frontal cortex of subjects with early infection were associated with an expansion of CD8(+) T cells, especially effector CD8(+) T cells.
Conclusions: These results verify metabolism changes occurring in the brain early during HIV infection. Lower NAA and Glx levels in the cortical gray matter suggests that HIV causes neuronal dysfunction soon after infection, which correlates to the expansion of CD8(+) T cells, specifically to an activated phenotype. Utilizing magnetic resonance spectroscopy to track NAA levels may provide important information on brain metabolic health while allowing better understanding of the virus-host interactions involved in CNS functional deficits.

AB Breast cancer development is a complex pathobiological process involving sequential genetic alterations in normal epithelial cells that results in uncontrolled growth in a permissive microenvironment. Accordingly, physiologically relevant models of human breast cancer that recapitulate these events are needed to study cancer biology and evaluate therapeutic agents. Here, we report the generation and utilization of the human breast cancer in mouse (HIM) model, which is composed of genetically engineered primary human breast epithelial organoids and activated human breast stromal cells. By using this approach, we have defined key genetic events required to drive the development of human preneoplastic lesions as well as invasive adenocarcinomas that are histologically similar to those in patients. Tumor development in the HIM model proceeds through defined histological stages of hyperplasia, DCIS to invasive carcinoma. Moreover, HIM tumors display characteristic responses to targeted therapies, such as HER2 inhibitors, further validating the utility of these models in preclinical compound testing. The HIM model is an experimentally tractable human in vivo system that holds great potential for advancing our basic understanding of cancer biology and for the discovery and testing of targeted therapies.

AB NFAT transcription factors are highly phosphorylated proteins residing in the cytoplasm of resting cells. Upon dephosphorylation by the phosphatase calcineurin, NFAT proteins translocate to the nucleus, where they orchestrate developmental and activation programs in diverse cell types. NFAT is rephosphorylated and inactivated through the concerted action of at least 3 different kinases: CK1, GSK-3, and DYRK. The major docking sites for calcineurin and CK1 are strongly conserved throughout vertebrate evolution, and conversion of either the calcineurin docking site to a high-affinity version or the CK1 docking site to a low-affinity version results in generation of hyperactivable NFAT proteins that are still fully responsive to stimulation. In this study, we generated transgenic mice expressing hyperactivable versions of NFAT1 from the ROSA26 locus. We show that hyperactivable NFAT increases the expression of NFAT-dependent cytokines by differentiated T cells as expected, but exerts unexpected signal-dependent effects during T cell differentiation in the thymus, and is progressively deleterious for the development of B cells from hematopoietic stem cells. Moreover, progressively hyperactivable versions of NFAT1 are increasingly deleterious for embryonic development, particularly when normal embryos are also present in utero. Forced expression of hyperactivable NFAT1 in the developing embryo leads to mosaic expression in many tissues, and the hyperactivable proteins are barely tolerated in organs such as brain, and cardiac and skeletal muscle. Our results highlight the need for balanced Ca/NFAT signaling in hematopoietic stem cells and progenitor cells of the developing embryo, and emphasize the evolutionary importance of kinase and phosphatase docking sites in preventing inappropriate activation of NFAT.

AB Background: Medication reconciliation at transitions in care is a national patient safety goal, but its effects on important patient outcomes require further evaluation. We sought to measure the impact of an information technology -based medication reconciliation intervention on medication discrepancies with potential for harm (potential adverse drug events [PADEs]).
Methods: We performed a controlled trial, randomized by medical team, on general medical inpatient units at 2 academic hospitals from May to June 2006. We enrolled 322 patients admitted to 14 medical teams, for whom amedication history could be obtained before discharge. The intervention was a computerized medication reconciliation tool and process redesign involving physicians, nurses, and pharmacists. The main outcome was unintentional discrepancies between preadmission medications and admission or discharge medications that had potential for harm (PADEs).
Results: Among 160 control patients, there were 230 PADEs (1.44 per patient), while among 162 intervention patients there were 170 PADEs (1.05 per patient) (adjusted relative risk [ARR], 0.72; 95% confidence interval [CI], 0.52-0.99). A significant benefit was found at hospital 1 (ARR, 0.60; 95% CI, 0.38-0.97) but not at hospital 2 (ARR, 0.87; 95% CI, 0.57-1.32) (P=.32 for test of effect modification). Hospitals differed in the extent of integration of the medication reconciliation tool into computerized provider order entry applications at discharge.
Conclusions: A computerized medication reconciliation tool and process redesign were associated with a decrease in unintentional medication discrepancies with potential for patient harm. Software integration issues are likely important for successful implementation of computerized medication reconciliation tools.

AB Background: To improve the documentation and treatment of tobacco use in primary care, we developed and implemented a 3-part electronic health record enhancement: (1) smoking status icons, (2) tobacco treatment reminders, and (3) a Tobacco Smart Form that facilitated the ordering of medication and fax and e-mail counseling referrals.
Methods: We performed a cluster-randomized controlled trial of the enhancement in 26 primary care practices between December 19, 2006, and September 30, 2007. The primary outcome was the proportion of documented smokers who made contact with a smoking cessation counselor. Secondary outcomes included coded smoking status documentation and medication prescribing.
Results: During the 9-month study period, 132 630 patients made 315 962 visits to study practices. Coded documentation of smoking status increased from 37% of patients to 54% (+ 17%) in intervention practices and from 35% of patients to 46% (+ 11%) in control practices (P <. 001 for the difference in differences). Among the 9589 patients who were documented smokers at the start of the study, more patients in the intervention practices were recorded as nonsmokers by the end of the study (5.3% vs 1.9% in control practices; P <. 001). Among 12 207 documented smokers, more patients in the intervention practices made contact with a cessation counselor(3.9% vs 0.3% in control practices; P <. 001). Smokers in the intervention practices were no more likely to be prescribed smoking cessation medication (2% vs 2% in control practices; P=.40).
Conclusion: This electronic health record-based intervention improved smoking status documentation and increased counseling assistance to smokers but not the prescription of cessation medication.

AB BACKGROUND: Currently, the preoperative diagnosis of a pancreatic cyst is based on clinical and imaging findings, frequently in conjunction with chemical analysis of cyst fluid and cytologic evaluation. The purpose of these diagnostic tests is to distinguish benign from malignant cysts of the pancreas. Accordingly, it is imperative to distinguish pancreatic pseudocysts from their mimics. In this study, the authors explored the cytomorphologic features of pseudocyst of the pancreas and evaluated the role of Alcian blue and mucicarmine stains in the cytologic evaluation of pancreatic cysts, METHODS: Forty-two patients were identified who had an eventual diagnosis of pancreatic pseudocyst and had an endoscopic ultrasoundguided fine-needle aspirate available. Clinical and imaging findings and chemical analyses of cyst fluid were recorded. The cytologic preparations were evaluated for gastrointestinal contamination, inflammatory cells, mucin, and pigmented material. The cytomorphologic features of 110 neoplastic mucinous cysts (intraductal papillary-mucinous neoplasms/mucinous cystic neoplasms of the pancreas) were evaluated and compared with the pseudocysts. RESULTS: The majority of patients (95%) had a prior episode of pancreatitis. On imaging, the pseudocysts were unilocular (92%). In 69% of cases, the endosonographic diagnosis was that of a pseudocyst. The mean carcinoembryonic antigen level was 41 ng/mL. In contrast, the cytopathologist rendered a definitive diagnosis of pseudocyst in only 10% of cases. The majority of smears (75%) revealed neutrophils and/or histiocytes. Atypical epithelial clusters were identified in 3 cases, I of which was diagnosed as suspicious for carcinoma. Yellow pigmented material, which was identified in 13 pseudocysts (31%), was not observed in neoplastic mucinous cysts. Alcian blue- and mucicarmine-positive material was identified in 64% and 40% of pseudocysts, respectively, and in 57% and 38% of neoplastic mucinous cysts, respectively. CONCLUSIONS: The diagnosis of a pseudocyst depended primarily on clinical and imaging findings and on chemical analysis of cyst fluid. The cytologic features frequently were nonspecific. The presence of yellow pigmented material served as a surrogate marker of a pseudocyst. Special stains for mucin did not distinguish pseudocysts from neoplastic mucinous cysts.

AB Adiponectin, one of the insulin-sensitizing adipokines, has been shown to activate fatty acid oxidation in liver and skeletal muscle, thus maintaining insulin sensitivity. However, the precise roles of adiponectin in fatty acid synthesis are poorly understood. Here we show that adiponectin administration acutely suppresses expression of sterol regulatory element-binding protein (SREBP) I c, the master regulator which controls and upregulates the enzymes involved in fatty acid synthesis, in the liver of +Lepr(db)/+Lep(db) (db/db) mouse as well as in Cultured hepatocytes. We also show that adiponectin suppresses SREBP1c by AdipoR1, one of the functional receptors for adiponetin, and furthermore that suppressing either AMP-activated protein kinase (AMPK) via its upstream kinase LKB1 deletion cancels the negative effect of adiponectin on SREBP1c expression. These data show that adiponectin suppresses SREBP1c through the AdipoR1/LKB1/AMPK pathway, and suggest a possible role for adiponectin in the regulation of hepatic fatty acid synthesis.

AB The Rassf1-6 polypeptides each contain a Ras/Rap association domain, which enables binding to several GTP-charged Ras-like GTPases, at least in vitro or when overexpressed. The Ras/Rap association domains are followed by SARAH domains, which mediate Rassf heterodimerization with the Mst1/2 protein kinases. Rassf1A is unequivocally a tumor suppressor, and all Rassf proteins behave like tumor suppressors, exhibiting epigenetic silencing of expression in many human cancers and proapoptotic and/or anti-proliferative effects when re-expressed in tumor cell lines. Herein, we review the binding of the Rassf polypeptides to Ras-like GTPases and the Mst1/2 kinases and their role in Rassf function.

AB We describe novel, cell-permeable, and bioavailable salicylic acid derivatives that are potent and selective inhibitors of GLEPP1/protein-tyrosine phosphatase phi. Two previously described GLEPP1 substrates, paxillin and Syk, are both required for cytoskeletal rearrangement and cellular motility of leukocytes in chemotaxis. We show here that GLEPP1 inhibitors prevent dephosphorylation of Syk1 and paxillin in resting cells and block primary human monocyte and mouse bone marrow-derived macrophage chemotaxis in a gradient of monocyte chemotactic protein-1. In mice, the GLEPP1 inhibitors also reduce thioglycolate-induced peritoneal chemotaxis of neutrophils, lymphocytes, and macrophages. In murine disease models, the GLEPP1 inhibitors significantly reduce severity of contact hypersensitivity, a model for allergic dermatitis, and dextran sulfate sodium-induced ulcerative colitis, a model for inflammatory bowel disease. Taken together, our data provide confirmation that GLEPP1 plays an important role in controlling chemotaxis of multiple types of leukocytes and that pharmacological inhibition of this phosphatase may have therapeutic use.

AB Structures of intact receptors with single-pass transmembrane domains are essential to understand how extracellular and cytoplasmic domains regulate association and signaling through transmembrane domains. A chemical and computational method to determine structures of the membrane regions of such receptors on the cell surface is developed here and validated with glycophorin A. An integrin heterodimer structure reveals association over most of the lengths of the alpha and beta transmembrane domains and shows that the principles governing association of hetero and homo transmembrane dimers differ. A turn at the Gly of the juxtamembrane GFFKR motif caps the alpha TM helix and brings the two Phe of GFFKR into the alpha/beta interface. A juxtamembrane Lys residue in beta also has an important role in the interface. The structure shows how transmembrane association/dissociation regulates integrin signaling. A joint ectodomain and membrane structure shows that substantial flexibility between the extracellular and TM domains is compatible with TM signaling.

AB The superior optical and electrical properties of quantum dot (QD) nanoparticles are being applied in a new generation of QD devices for microelectronic, nanophotonic, and biomedical systems. Research on integrated QD-based systems has been focused on passive manipulation of QDs including template-guided self-assembly, molecular scaffold-based assembly, and microbead-based assembly. However, little effort has been devoted to development of methods for active manipulation, such as positioning and concentration, of QDs. In this study, we show that 20 nm colloidal QDs can be effectively positioned and concentrated using a combination of dielectrophoresis (DEP) and AC electro-osmosis (ACEO). The long-range fluid motion generated by ACEO entrains QDs to the area near the electrode surface, which facilitates the trapping of QDs by DEP. A systematic investigation was performed to examine electrokinetic processes at different applied frequencies and voltages using a concentric electrode configuration. We demonstrate that QDs can be dynamically positioned with an electric field strength as small as 10 kV/m and define the operating parameters for increasing the concentration of colloidal QDs by 2 orders of magnitude within one minute.

AB AMP-activated protein kinase (AMPK) is a metabolic fuel gauge conserved along the evolutionary scale in eukaryotes that senses changes in the intracellular AMP/ATP ratio(1). Recent evidence indicated an important role for AMPK in the therapeutic benefits of metformin(2,3), thiazolidinediones(4) and exercise(5), which form the cornerstones of the clinical management of type 2 diabetes and associated metabolic disorders. In general, activation of AMPK acts to maintain cellular energy stores, switching on catabolic pathways that produce ATP, mostly by enhancing oxidative metabolism and mitochondrial biogenesis, while switching off anabolic pathways that consume ATP(1). This regulation can take place acutely, through the regulation of fast post-translational events, but also by transcriptionally reprogramming the cell to meet energetic needs. Here we demonstrate that AMPK controls the expression of genes involved in energy metabolism in mouse skeletal muscle by acting in coordination with another metabolic sensor, the NAD(+)-dependent type III deacetylase SIRT1. AMPK enhances SIRT1 activity by increasing cellular NAD(+) levels, resulting in the deacetylation and modulation of the activity of downstream SIRT1 targets that include the peroxisome proliferator-activated receptor-gamma coactivator 1 alpha and the forkhead box O1 (FOXO1) and O3 (FOXO3a) transcription factors. The AMPK-induced SIRT1-mediated deacetylation of these targets explains many of the convergent biological effects of AMPK and SIRT1 on energy metabolism.

Recent studies have revealed that Glut4 is also expressed in the brain, although the intracellular compartmentalization and regulation of Glut4 in neurons remains unknown. Using sucrose gradient centrifugation, immunoadsorption and immunofluorescence staining, we have shown that Glut4 in the cerebellum is localized in intracellular vesicles that have the sedimentation coefficient, the buoyant density, and the protein composition similar to the insulin-responsive Glut4-storage vesicles from fat and skeletal muscle cells. In cultured cerebellar neurons, insulin stimulates glucose uptake and causes translocation of Glut4 to the cell surface. Using (18)FDG ((18)fluoro-2-deoxyglucose) positron emission tomography, we found that physical exercise acutely increases glucose uptake in the cerebellum in vivo. Prolonged physical exercise increases expression of the Glut4 protein in the cerebellum. Our results suggest that neurons have a novel type of translocation-competent vesicular compartment which is regulated by insulin and physical exercise similar to Glut4-storage vesicles in peripheral insulin target tissues.

AB The generation of synthetic forms of cellular life requires solutions to the problem of how biological processes such as cyclic growth and division could emerge from purely physical and chemical systems. Small unilamellar fatty acid vesicles grow when fed with fatty acid micelles and can be forced to divide by extrusion, but this artificial division process results in significant loss of protocell contents during each division cycle. Here we describe a simple and efficient pathway for model protocell membrane growth and division. The growth of large multilamellar fatty acid vesicles fed with fatty acid micelles, in a solution where solute permeation across the membranes is slow, results in the transformation of initially spherical vesicles into long thread-like vesicles, a process driven by the transient imbalance between surface area and volume growth. Modest shear forces are then sufficient to cause the thread-like vesicles to divide into multiple daughter vesicles without loss of internal contents. In an environment of gentle shear, protocell growth and division are thus coupled processes. We show that model protocells can proceed through multiple cycles of reproduction. Encapsulated RNA molecules, representing a primitive genome, are distributed to the daughter vesicles. Our observations bring us closer to the laboratory synthesis of a complete protocell consisting of a self-replicating genome and a self-replicating membrane compartment. In addition, the robustness and simplicity of this pathway suggests that similar processes might have occurred under the prebiotic conditions of the early Earth.

AB Over 100 mutations in the gene encoding human copper-zinc superoxide dismutase (SOD1) cause an inherited form of the fatal neurodegenerative disease amyotrophic lateral sclerosis (ALS). Two pathogenic SOD1 mutations, His46Arg (H46R) and His48Gln (H48Q), affect residues that act as copper ligands in the wild type enzyme. Transgenic mice expressing a human SOD1 variant containing both mutations develop paralytic disease akin to ALS. Here we show that H46R/H48Q SOD1 possesses multiple characteristics that distinguish it from the wild type. These properties include the following: (1) an ablated copper-binding site, (2) a substantially weakened affinity for zinc, (3) a binding site for a calcium ion, (4) the ability to form stable heterocomplexes with the copper chaperone for SOD1 (CCS), and (5) compromised CCS-mediated oxidation of the intrasubunit disulfide bond in vivo. The results presented here, together with data on pathogenic SOD1 proteins coming from cell culture and transgenic mice, suggest that incomplete posttranslational modification of nascent SOD1 polypeptides via CCS may be a characteristic shared by familial ALS SOD1 mutants, leading to a population of destabilized, off-pathway folding intermediates that are toxic to motor neurons.
