Methods: The percentages of 190 American [100 after hip open reduction and interal fixation (ORIF) and 90 after ankle ORIF] and 116 Dutch patients (69 after hip ORIF and 47 after ankle ORIF) receiving inpatient and outpatient prescriptions for narcotics were retrospectively compared between countries, to test the hypothesis that narcotics are prescribed more frequently in the United States as compared with the Netherlands after operative fracture treatment. Results: Among patients with hip fractures, 85% of American and 58% of Dutch patients were prescribed narcotics during hospitalization (P < 0.001). After discharge, 77% of American and none of the Dutch patients were prescribed narcotics (p < 0.001). The multivariate model including country accounted for 11% of the variation in inpatient narcotic prescription (P < 0.001), and the model including country and surgeon accounted for 55% of the variation in outpatient narcotic prescription (p < 0.001). Among patients with ankle fracture, 98% of American and 64% of Dutch patients were prescribed narcotics during hospitalization (p < 0.001). After discharge, 82% of American patients and 6% of Dutch patients were prescribed narcotics (p < 0.001). Predictors included country and surgeon and they accounted for 20% of the variation in inpatient narcotics prescription (p < 0.001) and 49% of the variation in outpatient narcotic prescription (p < 0.001). Conclusions: American patients are prescribed significantly more inpatient and outpatient narcotic pain medication than Dutch patients after operative treatment of hip and ankle fractures.

TI Sexual Mixing Patterns and Partner Characteristics of Black MSM in Massachusetts at Increased Risk for HIV Infection and Transmission SO JOURNAL OF URBAN HEALTH-BULLETIN OF THE NEW YORK ACADEMY OF MEDICINE LA English DT Article DE HIV/AIDS; STD; African American/Black; MSM; Prevention ID PERCEIVED SOCIAL SUPPORT; AFRICAN-AMERICAN MEN; UNITED-STATES; GAY MEN; CAGE QUESTIONNAIRE; PSYCHOMETRIC EVALUATION; MULTIDIMENSIONAL SCALE; TRANSMITTED-DISEASES; HIDDEN POPULATIONS; ANAL INTERCOURSE AB Black men who have sex with men (MSM) are at increased risk for HIV infection in the United States compared to other MSM. The aim of this study was to investigate Black MSM's sexual mixing patterns and partner characteristics in relation to sexual risk taking, as a possible explanation for this observed increase in HIV incidence. Between January and July 2008, 197 Black MSM were recruited via modified respondent-driven sampling and completed optional pretest and post-test HIV serological testing, counseling, and a demographic, behavioral, and psychosocial assessment battery. Bivariate and multivariable logistic regression procedures were used to examine predictors of risky sex across partner types. Overall, 18% of the sample was HIV-infected; 50% reported unprotected intercourse with men, 30% with women, and 5% with transgender partners. Fifty-three percent identified as bisexual or straight, although all reported oral or anal sex with another man in the prior 12 months. Significant predictors of engaging in at least one episode of: (1) serodiscordant unprotected anal sex (UAS) with a male partner in the past 12 months: individuals at risk for social isolation (AOR = 4.23; p = 0.03), those with unstable housing (AOR = 4.19; p = 0.03), and those who used poppers at least weekly during sex (AOR = 5.90; p = 0.05); (2) UAS and/or unprotected vaginal intercourse with a female partner in the past 12 months: those with unstable housing (AOR = 4.85; p = 0.04), those who used cocaine at least weekly during sex (AOR = 16.78; p = 0.006), being HIV-infected (AOR = 0.07; p = 0.02), and feeling social norms favor condom use (AOR = 0.60; p = 0.05); (3) UAS with the participants' most recent nonmain male sex partner: use of alcohol and drugs during last sex by participant (AOR = 4.04; p = 0.01), having sex with a Hispanic/Latino male (AOR = 2.71; p = 0.04) or a Black male (AOR = 0.50; p = 0.05) compared to a White male, and lower education (AOR = 1.31; p = 0.02). Findings suggest that sexual risk behaviors of Black MSM differ across partner type and by the characteristics of their sexual networks and that this subpopulation of MSM are at high risk for HIV acquisition and transmission. Effective prevention strategies need to address the distinct sexual and behavioral risk patterns presented by different sexual partnerships reported by Black MSM.

TI Thoracoabdominal aneurysm repair: Hybrid versus open repair SO JOURNAL OF VASCULAR SURGERY LA English DT Article ID THORACIC AORTIC-ANEURYSMS; OPEN-SURGICAL REPAIR; HIGH-RISK PATIENTS; ENDOVASCULAR TREATMENT; STENT-GRAFT; TRIAL; OUTCOMES; IV; REVASCULARIZATION; EXPERIENCE AB Objective: Hybrid repair of thoracoabdominal aortic aneurysms (TAAA) may reduce morbidity and mortality in high-risk candidates for open repair. This study reviews the outcomes of hybrid TAAA repair for Crawford extent I-III TAAA in high-risk patients in comparison to patients who underwent concurrent open TAAA repair. Methods. During the interval from June 2005 to December 2007, a total of 23 high-risk patients with TAAA (type 1: 9 [39%], 11: 5 [22%], and 111: 9 [39%]) underwent renal and/or mesenteric debranching (11 [48%] with four vessel debranching) with subsequent placement of a thoracic stent graft; 77 patients underwent open TAAA repair (type 1: 13 [17%], 11: 11 [14%], 111: 27 [35%], and IV: 26 [34%]) during the same interval. The primary high-risk criteria for hybrid TAAA included advanced age/poor functional status (n = 14), major pulmonary dysfunction (n = 8), and technical consideration (prior thoracic aortic aneurysm repair [n = 4] or prior thoracoabdominal aneurysm repair [n = 21 and obesity [n = 21) with 6 patients having overlapping high-risk criteria. Composite (30-day) mortality and/or permanent paraplegia (PP) were the major study endpoints. Results: The hybrid and open TAAA groups had (respectively) no statistical difference in mean age (76.6 vs 72.7 years), aneurysm size (6.51 vs 6.52 cm), and non-elective operation (30.4% vs 26.0%). The hybrid group had a higher mean Society for Vascular Surgery (SVS) risk score (9.1 vs 6.0; P <= .001), incidence of oxygen-dependent chronic obstructive pulmonary disease (COPD) (34.8% vs 2.6%; P <= .001), and prior thoracic (n = 4) or thoracoabdominal (n = 2) repair (26.1% vs 1.3%; P <= .001). Composite mortality and/or PP was doubled in the hybrid group (21.7% vs 11.7%; P = .33). The rate of any type of reoperation was higher in hybrid TAAA repair (39.1% vs 20.8%; P = .03). One year actuarial survival for both groups was comparable (hybrid, 68 +/- 12%; open, 73 +/- 6%). A total of 5/23 (22%) hybrid TAAA patients developed an endoleak (type I: 3/23 and type II : 2/23) with 3 requiring endovascular re-intervention. A total of 7/70 (10%) visceral/renal bypass grafts were noted to be occluded during follow-up (I superior inesenteric artery, 1 celiac, and 5 renal). Examination of patients with an SVS risk score :58 (mean SVS risk score in hybrid 6.2 [n = 10] vs 5.5 [n = 68] in open; P = .27) revealed the hybrid group had a higher incidence of composite mortality and/or PP (40% vs 10.3%; P = .03). Conclusion: Hybrid TAAA repair in high-risk patients has significant morbidity and mortality suggesting a non-interventional approach may be appropriate in many such patients. The morbidity and mortality of the hybrid TAAA repair was substantial even in lower risk patients (SVS risk score <= 8), albeit patient numbers were small. Prospective study in comparable patient risk cohorts is required to define the role of hybrid TAAA repair. (J Vasc Surg 2009;50: 15-22.)

Epidemiological and functional studies have shown an important role of NK cells expressing specific killer immunoglobulin-like receptors (KIRs) in the control of human immunodeficiency virus type 1 (HIV-1) infection, but little is known about the mechanisms that determine the expansion of these antiviral NK cell populations during acute HIV-1 infection. Here we demonstrate that NK cells expressing the activating receptor KIR3DS1(+) and, to a lesser extent, the inhibitory receptor KIR3DL1(+) specifically expand in acute HIV-1 infection in the presence of HLA-B Bw480I, the putative HLA class I ligand for KIR3DL1/3DS1. These data demonstrate for the first time the HLA class I subtype-dependent expansion of specific KIR+ NK cells during an acute viral infection in humans.

TI Evaluating Preference-Sensitive Care for Uterine Fibroids: It's Not So Simple SO JOURNAL OF WOMENS HEALTH LA English DT Article ID RANDOMIZED CONTROLLED-TRIAL; DECISION-MAKING; REGIONAL-VARIATIONS; PATIENT DECISION; HEALTH OUTCOMES; MEDICAL-CARE; NEW-HAVEN; QUALITY; AIDS; SUPPORT AB Background: Preference-sensitive care decisions should reflect an informed patient's preferences. This retrospective survey of women with fibroids, a benign condition with multiple treatment options, sought to evaluate the extent to which this was measurable and true. Methods: All 260 women in one medical group with visit codes for uterine fibroids during a 9-month period in 2006 were mailed surveys constructed through focus groups with physicians and interviews with patients. Correlations tested associations among their preferences, knowledge, and treatment decisions. Results: The adjusted response rate was 82%, but only 100 respondents fit all criteria for analysis. Nearly all wanted to either share or control the decision, and 86% felt informed, satisfied, and that the decision was consistent with their values. However, only 55% of patients could answer at least five of seven fibroid questions correctly. Hysterectomy use was significantly correlated with desire to relieve symptoms, have a permanent treatment, and do something right away (r = 0.36, 0.37, and 0.30, respectively). Those deciding not to treat were significantly less likely to have these preferences (r = -0.65, -0.40, and -0.58). These relationships were not affected by patient knowledge level, but patients with high knowledge scores were significantly more likely to believe their decision was concordant with their preferences (94.9% vs. 74.4%, p<0.01). Conclusions: There were knowledge gaps but unclear associations between knowledge and decision-preference relationships for this condition, which has many different treatment alternatives. A prospective intervention trial is needed to determine if better information and counseling would produce stronger concordance between treatment selected and patient preferences.

Complete Stat3 gene knockout is embryonic lethal; therefore, we crossed Stat3+/- mice with Stat3 mutant mice (SA/SA) that lack full Stat3 activity. This strategy generated Stat3SA/- mice (25% activity) and Stat3SA/+ mice (75% activity), which were made diabetic using streptozotocin in order to define the role of Stat3 in diabetic kidney disease. While the glomerular number was not different between these two groups of mice, the diabetic SA/- mice had significantly less proteinuria, mesangial expansion, glomerular cell proliferation, and macrophage infiltration than the diabetic SA/+ mice. The reduction in Stat3 activity did not affect glomerular hyperfiltration seen after the induction of diabetes, as it was increased to the same degree in both groups of mice. Phosphorylation of Stat3 was markedly increased in the glomeruli of diabetic SA/+ mice compared to diabetic SA/- mice. The expression of inflammatory markers, IL-6, MCP-1, and activated NF-kappa B; type IV collagen, TGF-beta, and ICAM-1 mRNA; or type IV collagen and TGF-beta protein, were all found to be significantly less in glomeruli isolated from diabetic SA/- mice, as compared with diabetic SA/+ mice. Our study shows that Stat3 plays a critical role in the regulation of inflammation and abnormal matrix synthesis at an early stage of DN.

This study evaluates the intraoperative placement of the voice prosthesis at the time of the primary TEP in an effort to understand the potential advantages and disadvantages of voice prosthesis placement at the time of primary TEP completed in conjunction with total laryngectomy. Study Design: Retrospective chart review within an academic medical center. Methods: After approval by the institutional review board of the Massachusetts Eye and Ear Infirmary, a retrospective chart review was completed of all cases of primary tracheoesophageal prosthesis placement completed in conjunction with primary tracheoesophageal puncture performed at the time of total laryngectomy. Results: Thirty patients were identified, 29 of whom underwent laryngectomy for advanced laryngeal carcinoma. Twenty-eight of 29 patients received preoperative full-dose radiation therapy. Twenty-nine of 30 patients had a 20F classic Indwelling Blom-Singer prosthesis (InHealth Technologies, Carpinteria, CA) placed. One had placement of 16F Indwelling Blom-Singer prosthesis. No complications were noted with intraoperative prosthesis placement. No prostheses were dislodged in the postoperative period. Twenty-nine of 30 subjects had initial success with tracheoesophageal voice production. At 1-year follow-up, 23/30 subjects (77%) had successful voice restoration. Five failed because of recurrent disease, one subject never achieved successful voice, and one subject wanted the prosthesis removed although successful voice was achieved. Twenty-three of 25 (92%) disease-free subjects had functional voice restoration at 1-year post-total laryngectomy and primary prosthesis placement. Conclusions: This study demonstrates that the voice prosthesis can be safely and effectively placed intraoperatively at the time of primary TEP and laryngectomy. Initial voice acquisition rates were high and long-term success was well within the acceptable range.

TI Treatment of Helicobacter pylori Infection With Intra-Gastric Violet Light Phototherapy: A Pilot Clinical Trial SO LASERS IN SURGERY AND MEDICINE LA English DT Article DE Helicobacter pylori; gastroenterology; laser phototherapy; porphyrins; endoscopy ID PHOTODYNAMIC THERAPY; PROPIONIBACTERIUM-ACNES; VISIBLE-LIGHT; ERADICATION; PORPHYRINS; QUADRUPLE; BACTERIA AB Background and Objective: Helicobacter pylori infects the mucus layer of the human stomach and causes peptic ulcers and adenocarcinoma. We have previously shown that H. pylori accumulates photoactive porphyrins making the organism susceptible to inactivation by light, and that small spot endoscopic illumination with violet light reduced bacterial load in human stomachs. This study assessed the feasibility and safety of whole-stomach intra-gastric violet phototherapy for the treatment of H. pylori infection. Study Design/Materials and Methods: A controlled, prospective pilot trial was conducted using a novel light source consisting of laser diodes and diffusing fibers to deliver 408-nm illumination at escalating total fluences to the whole stomach. Eighteen adults (10 female) with H. pylori infection were treated at three U.S. academic endoscopy centers. Quantitative bacterial counts were obtained from biopsies taken from the antrum, body, and fundus, and serial urea breath tests. Results: The largest reduction in bacterial load was in the antrum (>97%), followed by body (>95%) and fundus (>86%). There was a correlation between log reduction and initial bacterial load in the antrum. There was no dose-response seen with increasing illumination times. The urea breath test results indicated that the bacteria repopulated in days following illumination. Conclusion: Intra-gastric violet light phototherapy is feasible and safe and may represent a novel approach to eradication of H. pylori, particularly in patients who have failed standard antibiotic treatment. This was a pilot study involving a small number of patients. Further research is needed to determine if phototherapy can be effective for eradicating H. pylori. Lasers Surg. Med. 41:337-344, 2009.

In particular, phenothiazine compounds have demonstrated efficacy for PDT of CL. The objective of our present study is to define the use of a new specific phenothiazine photosensitizer, 3,7-bis(di-n-butylamino)phenothiazin-5-ium bromide (PPA904) applied topically as a cream to treat CL. Materials and Methods: To establish the optimal conditions for this treatment, we compared two different ways to improve current regimens of PDT with PPA904 cream (500 mu M of PPA904 in Unguentum M) by changing the duration of topical application, and by administration of several consecutive PDT procedures. An initial regimen recommended by the manufacturer (Photopharmica Co. Ltd., Leeds, UK) was maintained as a control: the cream was applied topically for 30 minutes at a final concentration of PPA904 at 500 mu M, and the designated treatment area was irradiated with a broad band light source of 665 +/- 15 nm at a fluence of 50 J/cm(2) (50 MW/cm(2)). Results: The best curative PPA904-PDT regimen was achieved under the conditions of a longer duration of topical application time (90 minutes) and several (three) consecutive treatments with 4-day intervals between treatments. The mechanisms responsible for such improvements (kinetics of drug penetration, depth of necrosis of the CL lesions after PDT, and daily changes in the parasitic load after PDT) are discussed in the present study. Conclusion: Topical PPA904-PDT, implemented as described above, is a promising treatment for CL, and clinical studies will be initiated to establish efficacy in humans. Lasers Surg.

Genome scale studies, using chromatin immunoprecipitation followed by expression arrays ('ChIP-Chip') or next generation sequencing ('ChIP-Seq'), have been applied to the study of transcription factor binding, DNA methylation, alternative histone use, and covalent histone modifications such as acetylation, ubiquitination and methylation. Initial studies focused on yeast, and embryonic stem cells. Genome-wide studies are now also being employed to characterize cancer and specifically leukemia genomes, with the prospect of improved diagnostic accuracy and discovery of novel therapeutic strategies.

We investigated whether rates of patient safety indicators (PSIs) changed after these reforms. Research Design: Observational study of patients admitted to Veterans Health Administration (VA) (N = 826,047) and Medicare (N = 13,367,273) acute-care hospitals from July 1, 2000 to June 30, 2005. We examined changes in patient safety events in more versus less teaching-intensive hospitals before (2000-2003) and after (2003-2005) duty hour reform, using conditional logistic regression, adjusting for patient age, gender, comorbidities, secular trends, baseline severity, and hospital site. Measures: Ten PSIs were aggregated into 3 composite measures based on factor analyses: "Continuity of Care," "Technical Care," and "Other" composites. Results: Continuity of Care composite rates showed no significant changes postreform in hospitals of different teaching intensity in either VA or Medicare. In the VA, there were no significant changes postreform for the technical care composite. In Medicare, the odds of a Technical Care PSI event in more versus less teaching-intensive hospitals in postreform year 1 were 1.12 (95% CI; 1.01-1.25), there were no significant relative changes in postreform year 2. Other composite rates increased in VA in postreform year 2 in more versus less teaching-intensive hospitals (odds ratio, 1.63; 95% CI; 1.10-2.41), but not in Medicare in either postreform year. Conclusions: Duty hour reform had no systematic impact on PSI rates. In the few cases where there were statistically significant increases in the relative odds of developing a PSI, the magnitude of the absolute increases were too small to be clinically meaningful.

SO MEDICAL CARE LA English DT Article DE breast cancer; surgery; quality; racial disparities ID ACUTE MYOCARDIAL-INFARCTION; HEALTH-SERVICES RESEARCH; BLACK-AND-WHITE; COMORBIDITY INDEX; LINKED MEDICARE; LUNG-CANCER; DISPARITIES; VOLUME; SURVIVAL; CARE AB Background: Prior research has documented racial disparities in patterns of care and outcomes for women with breast cancer. Objectives: To assess whether black women receive care from lower-quality or lower-volume hospitals and if such differences explain disparities in receipt of definitive primary breast cancer therapy. Research Design: Observational study of a population-based sample of breast cancer patients included in the SEER-Medicare database. Subjects: Fifty five thousand four hundred seventy white or black women aged >65 diagnosed with stage I/II breast cancer during 1992-2002. Measures: Surgery at a high-quality hospital (top quartile rates of radiation after breast-conserving Surgery) or high volume (top quartile) hospital and receipt of definitive primary therapy (mastectomy or breast-conserving surgery with radiation). Results: Black women were significantly less likely than white women to be treated at high-quality hospitals (adjusted odds ratio [OR] 0.60; 95% confidence interval [Cl]: 0.40-0.87) but not high-volume hospitals (adjusted OR 0.85; 95% Cl: 0.54-1.34). Black women were less likely than white women to receive definitive primary therapy, a finding partially explained by having surgery at a high-quality hospital but not by having surgery at a high-volume hospital. Conclusions: Older black women were more likely than white women to undergo breast cancer surgery at hospitals with lower rates of radiation following breast-conserving surgery, and this explains some of the reported racial disparities previously observed in receipt of definitive therapy for early-stage breast cancer. Interventions to help hospitals treating large numbers of black women improve rates of radiation after breast-conserving surgery may help to decrease racial disparities in care.

Few studies, however, have considered race and sex disparities in the timing and appropriateness of treatment across stages of diagnosis. Objective: To evaluate the relationship of sex and race with the receipt of timely and clinically appropriate NSCLC treatment for each stage of diagnosis. Method: Surveillance Epidemiology and End Result data linked to Medicare claims for beneficiaries diagnosed with NSCLC between 1995 and 1999 were used to evaluate the relationship between race and sex with timely and appropriate NSCLC treatment while controlling for other demographic characteristics, comorbidities, socioeconomic status, and provider supply (N = 22,145). Results: Overall adjusted rates of timely and appropriate treatment are 37.2%, 58.1%, and 29.2% for Medicare beneficiaries diagnosed with stage I or 11, 111, and IV NSCLC, respectively. Among stage I or 11 patients, women were 25% less likely to receive timely Surgical resection relative to men, and blacks were 66% less likely to receive timely and appropriate treatment than whites. Black men were least likely to receive resection (22.2% compared with 43.7% for white men). Blacks were 34% less likely to receive timely surgery, chemotherapy, or radiation for stage III disease and were 51% less likely to receive chemotherapy in a timely fashion for stage IV disease relative to whites. Conclusion: Significant variations in appropriate timely treatment were found within and across stages of diagnosis, confirming that sex and race differences in NSCLC treatment exist.

These transfers may be particularly important in critical care, where small relative improvements can yield substantial absolute changes in survival. Objective: To characterize the existing critical care network in terms of the pattern of transfers. Methods: In a retrospective cohort study, the nationwide 2005 Medicare fee-for-service claims were used to identify the interhospital transfer of critically ill patients, defined as instances where patients used critical care services in 2 temporally adjacent hospitalizations. Measurements: We Measured the characteristics of the interhospital transfer network and the extent to which intensive care unit patients are referred to each hospital in that network-a continuous quantitative measure at the hospital-level known as centrality. We evaluated associations between hospital centrality and organizational, medical, surgical, and radiologic capabilities. Results: There were 47,820 transfers of critically ill patients among 3308 hospitals. 4.5% of all critical care stays of any length involved an interhospital critical care transfer. Hospitals transferred out to a mean of 4.4 other hospitals. More central hospital positions were associated with multiple indicators of increased capability. Hospital characteristics explained 40.7% of the variance in hospitals' centrality. Conclusions: Critical care transfers are common, and traverse an informal but structured network. The centrality of a hospital is associated with increased capability in delivery of services, suggesting that existing transfers generally direct patients toward better resourced hospitals. Studies of this network promise further improvements in patient outcomes and efficiency of care. C1 [Iwashyna, Theodore J.] Univ Michigan, Dept Med, Div Pulm & Crit Care, Ann Arbor, MI 48109 USA.

There is agreement that all relevant services be valued from the societal perspective using a long-term time horizon and that more exact methods be used to cost services most affected by the Study intervention. Guidelines are not specific enough with respect to costing methods, however. Method: The literature was reviewed to identify the problems associated with the 4 principal methods of cost determination. Findings: Microcosting requires direct measurement and is ordinarily reserved to cost novel interventions. Analysts should include nonwage labor cost, person-level and institutional overhead, and the cost of development, set-up activities, supplies, space, and screening. Activity-based cost systems have promise of finding accurate costs of all services provided, but are not widely adopted. Quality must be evaluated and the generalizability of cost estimates to other settings must be considered. Administrative cost estimates, chiefly cost-adjusted charges, are widely used, but the analyst must consider items excluded from the available system. Gross costing methods determine quantity of services used and employ a unit cost. If the intervention will affect the characteristics of a service, the method should not assume that the service is homogeneous. Conclusions: Questions are posed for future reviews of the quality of costing methods. The analyst must avoid inappropriate assumptions, especially those that bias the analysis by exclusion of costs that are affected by the intervention under study.

The objective of this study was to compare 3 approaches for estimating the incidence costs of colorectal cancer (CRC) care using similar patient populations, but different data sources and methods. Methods: We used 2 data sources, linked SEER-Medicare and Medicare claims alone, to identify newly diagnosed CRC patients aged 65 and older and estimated their healthcare costs during the observation period, 1998 to 2002. Controls were matched by sex, age-group, and geographic location. We compared mean net costs, measured as the difference in total cost between cases and controls, for: (1) a SEER-Medicare cohort, (2) a Medicare claims alone cohort, and (3) a modeled phase of care approach using linked SEER-Medicare data. The SEER-Medicare cohort approach was considered the reference. Results: We found considerable variability across approaches for estimating net costs of care in CRC patients. In the first year after diagnosis, mean net costs were $32,648 (95% CI: $31,826 and $33,470) in the SEER-Medicare cohort. The other approaches understated mean net costs in year 1 by about 16%. Mean net 5-year costs of care were $37,227 (95% CI: $35,711 and $38,744) in the SEER-Medicare cohort, and $30,310 (95% CI: $25,894 and $34,726) in the claims only approach, with the largest difference in the 65 to 69 age group. Mean net 5-year costs of care were more similar to the reference in the modeled phase of care approach ($37,701 [range: $36,972 and $38,4461]). Differences from the SEER-Medicare cohort estimates reflect misclassification of prevalent cancer patients as newly diagnosed patients in the Medicare claims only approach, and differences in years of data and assumptions about comparison groups in the modeled phase of care approach. Conclusions: CRC incidence cost estimates vary substantially depending on the strategy and data source for identifying newly diagnosed cancer patients and methods for estimating longitudinal costs. Our findings may inform estimation of costs for other cancers as well as other diseases. C1 [Yabroff, K.

SO MEDICAL CARE LA English DT Article DE health care costs; health services research; cost and cost analysis; colorectal neoplasms; Medicare; SEER program; MEPS ID SEER-MEDICARE DATA; UNITED-STATES; LIFE AB Background: National prevalence costs of medical care can be key inputs in health policy decisions. Cost estimates vary across data sources, patient populations, and methods, however, the objective of this study was to compare 3 approaches for estimating the prevalence costs of colorectal cancer (CRC) care using different data sources, but similar patient populations and methods. Methods: We identified prevalent CRC patients aged 65 and older from: (1) linked Surveillance Epidemiology and End Results (SEER) registry-Medicare data, (2) Medicare claims only, and (3) the Medical Expenditure Panel Survey (MEPS). Controls were matched by sex, age-group, and geographic location. Mean per person total and net costs, measured as the difference between patients and controls, were compared for each approach during a similar observation period. The SEER-Medicare approach was our reference, and we evaluated the impact of patient selection criteria with sensitivity analyses. Aggregate prevalence estimates were also compared. Results: We found considerable variability across the different approaches to estimating prevalence costs of CRC. Mean net annual per person estimates in the SEER-Medicare reference were $5341 (95% CI: $5243, $5439), compared with $8736 (95% CI: $8203, $9269) for the Medicare claims only and $11,614 (95% CI: $7566, $15,663) for the MEPS. Aggregate national estimates of net prevalence costs of CRC in 2004 ranged from $4524 million, using the SEER-Medicare approach, to $9629 million, using the MEPS approach. Estimates varied by data source based on the payors included and identification of prevalent CRC patients. Conclusions: CRC prevalence cost estimates vary substantially depending on the data sources. Our findings have implications for estimating prevalence costs for other cancers and other diseases without registry systems that can be used to identify newly diagnosed individuals as well as those diagnosed less recently.

A diagnosis of metastatic breast cancer (BC) forces patients and providers to make difficult treatment decisions. Objective. To pilot test a decision aid (DA) for advanced BC. Design. Pretest, posttest study. Setting. Two academic cancer centers in Boston, Massachusetts. Patients. Fifty patients diagnosed with advanced BC. Intervention. A patient DA that consisted of a 30-minute DVD and booklet. Measurements. Patients were surveyed at baseline, after the intervention, and at 3 months. Measures included use and acceptability of DA, distress, treatment goals, and preference for and actual participation in decisions. Physicians were surveyed at baseline and 3 months. Measures included treatment goals, assessment of patients' experience with treatments, and patients' preference for and actual participation in decisions. Results. Thirty-two patients (64%) enrolled and completed the baseline survey, 30 completed the postvideo survey, and 25 completed the 3-month survey. The DA was acceptable and did not increase distress. The majority desired to share decision making with their doctor. Only 38% achieved their desired level of participation. At baseline, agreement between patients and providers on the main goal of treatment (lengthen life v. relieve symptoms) was 50% (kappa = -0.045, P = 0.71), and at 3 months it was 74% (kappa = 0.125, P = 0.48). Conclusions. It is feasible to perform a clinical trial of a DA with advanced BC patients. Most participants wanted to participate in decisions about their care and found the DA acceptable. This study highlights several issues in developing and implementing DAs in this vulnerable population facing complex decisions.

Burr Proton Therapy Center field specific output factors (i.e., dose per monitor unit) for patient treatments were modeled for all beamlines (two gantries, fixed stereotactic, and fixed eye beamline). The authors evaluated the accuracy of dose calculation and output model for small fields. Measurements in a water phantom were performed in three of our beamlines quantifying the dependency of the output factor on the field size for a variety of proton ranges. The influence of snout size, air gap, modulation, and second scatterer was investigated. The impact of field size on output depends strongly on the depth of interest. The air gap has a notable influence on small field outputs. A field size specific correction factor to the output is necessary if the latter was modeled or measured without the custom hardware in place. The output was shown to be field size dependent even for large fields, indicating an effect beyond charged particle disequilibrium caused by lateral scatter.

In the present study, we explored the mechanisms underlying these benefits and costs by examining the performance of amnesic and control groups in a forced choice perceptual identification (FCPI) task in which briefly flashed words (that were identical to studied words, similar to studied words, or new) had to be identified, and two response choices were provided that differed from each other by one letter. Control participants showed a performance benefit and cost in FCPI with both high- and low-frequency words. Amnesic participants showed a benefit (but no cost) with high-frequency words and a benefit and a cost with low-frequency words. The benefit/cost pattern with low-frequency words in amnesia was obtained even when the to-be-identified stimulus in the FCPI task was eliminated (Experiment 2), suggesting that this effect was driven by processes operating at the level of the response choices. Our findings suggest that implicit memory effects in FCPI reflect the operation of multiple mechanisms, the relative contributions of which may vary with the frequency of the test stimuli. The results also highlight the need for caution in interpreting results from normal participants in the FCPI task, since those findings may reflect a contribution of explicit memory processes.

Methods: We analyzed data from the Heart and Estrogen/Progestin Replacement Study, a randomized, placebo-controlled trial of 0.625 mg conjugated equine estrogens plus 2.5 mg medroxyprogesterone acetate in 2,763 postmenopausal women with CHD. Hot flushes were assessed at baseline using self-administered questionnaires; women reporting bothersome hot flushes "some" to "all" of the time were considered to have clinically significant flushing. Cox regression models were used to examine the effect of EPT on risk of CHD events among women with and without significant flushing at baseline. Results: The mean age of participants was 66.7 +/- 6.8 years, and 89% (n = 2,448) were white. Sixteen percent (n = 434) of participants reported clinically significant hot flushes at baseline. Among women with baseline flushing, EPT increased risk of CHD events nine-fold in the first year compared with placebo (hazard ratio = 9.01; 95% CI, 1.15-70.35); among women without baseline flushing, treatment did not significantly affect CHD event risk in the first year (hazard ratio = 1.32; 95% CI, 0.86-2.03; P = 0.07 for interaction of hot flushes with treatment). The trend toward differential effects of EPT on risk for CHD among women with and without baseline flushing did not persist after the first year of treatment. Conclusions: Among older postmenopausal women with CHD, EPT may increase risk of CHD events substantially in the first year of treatment among women with clinically significant hot flushes but not among those without hot flushes.

TI Depression is associated with worse objectively and subjectively measured sleep, but not more frequent awakenings, in women with vasomotor symptoms SO MENOPAUSE-THE JOURNAL OF THE NORTH AMERICAN MENOPAUSE SOCIETY LA English DT Article DE Vasomotor symptoms; Hot flashes; Sleep; Insomnia; Depression; Mood ID MENOPAUSAL HOT FLASHES; DATA-ANALYSIS SOFTWARE; PERIMENOPAUSAL WOMEN; POSTMENOPAUSAL WOMEN; WAKE ACTIVITY; PRIMARY-CARE; TRANSITION; INSOMNIA; DISTURBANCE; ACTIGRAPHY AB Objective: Depression occurs more commonly during the menopausal transition in women with vasomotor symptoms (VMS) than in those without, but most women with VMS do not develop depression. It has been hypothesized that VMS are associated with depression because VMS lead to repeated awakenings, which impair daytime well-being. We aimed to determine if objectively measured sleep and perceived sleep quality are worse in depressed women with VMS than in nondepressed women with VMS. Methods: Objectively and subjectively measured sleep parameters were compared between 52 depressed women with VMS and 51 nondepressed controls with VMS. Actigraphic measures of objective sleep conducted in the home environment and subjective measures of sleep quality (Pittsburgh Sleep Questionnaire Index) were compared using linear regression models. Results: On objective assessments, depressed women with VMS spent less time in bed (by 64.8 min; P < 0.001) and had shorter total sleep time (by 47.7 min; P = 0.008), longer sleep-onset latency (by 13.8 min; P = 0.03), and lower sleep efficiency (by 3.2 percentage points; P = 0.09), but did not awaken more or spend more time awake after sleep onset than nondepressed controls with VMS. Depressed women also reported worse sleep quality (mean Pittsburgh Sleep Questionnaire Index 12.0 vs 8.3; P < 0.001). Adjustment for VMS frequency and important demographic characteristics did not alter these associations. Conclusions: Sleep quality and selected parameters of objectively measured sleep, but not sleep interruption, are worse in depressed than in nondepressed women with VMS. The type of sleep disturbance seen in depressed participants was not consistent with the etiology of depression secondary to VMS-associated awakenings.

We hypothesized that metabolic preconditioning via ex vivo perfusion of the liver graft can reduce fat content and increase post-transplant survival to an acceptable range. We describe a perfusate medium containing agents that promote the defatting of hepatocytes and explanted livers. Defatting agents were screened on cultured hepatocytes made fatty by pre-incubation with fatty acids. The most effective agents were then used on fatty livers. Fatty livers were isolated from obese Zucker rats and normothermically perfused with medium containing a combination of defatting agents. This combination decreased the intracellular lipid content of cultured hepatocytes by 35% over 24h, and of perfused livers by 50% over 3h. Metabolite analysis suggests that the defatting cocktail upregulated both lipid oxidation and export. Furthermore, gene expression analysis for several enzymes and transcription factors involved in fatty acid oxidation and triglyceride clearance were elevated. We conclude that a cocktail of defatting agents can be used to rapidly clear excess lipid storage in fatty livers, thus providing a new means to recondition donor livers deemed unacceptable or marginally acceptable for transplantation.

Inhibition of SIRT1 reactivates silenced genes, suggesting a possible therapeutic approach of targeted reversal of aberrantly silenced genes. In addition, SIRT1 may be involved in the well-known link between obesity, cellular energy balance and cancer. However, a comprehensive study of SIRT1 using human cancer tissue with clinical outcome data is currently lacking, and its prognostic significance is uncertain. Using the database of 485 colorectal cancers in two independent prospective cohort studies, we detected SIRT1 overexpression in 180 (37%) tumors by immunohistochemistry. We examined its relationship to the CpG island methylator phenotype (CIMP), related molecular events, clinical features including body mass index, and patient survival. We quantified DNA methylation in eight CIMP-specific promoters (CACNA1G, CDKN2A, CRABP1, IGF2, MLH1, NEUROG1, RUNX3, and SOCS1) and eight other CpG islands (CHFR, HIC1, IGFBP3, MGMT, MINT1, MINT31, p14, and WRN) by MethyLight. SIRT1 overexpression was associated with CIMP-high (>= 6 of 8 methylated CIMP-specific promoters, P = 0.002) and microsatellite instability (MSI)-high phenotype (P<0.0001). In both univariate and multivariate analyses, SIRT1 overexpression was significantly associated with the CIMP-high MSI-high phenotype (multivariate odds ratio, 3.20; 95% confidence interval, 1.35-7.59; P = 0.008). In addition, mucinous component (P = 0.01), high tumor grade (P = 0.02), and fatty acid synthase overexpression (P = 0.04) were significantly associated with SIRT positivity in multivariate analysis. SIRT1 was not significantly related with age, sex, tumor location, stage, signet ring cells, cyclooxygenase-2 (COX-2), LINE-1 hypomethylation, KRAS, BRAF, BMI, PIK3CA, HDAC, p53, beta-catenin, COX-2, or patient prognosis. In conclusion, SIRT1 expression is associated with CIMP-high MSI-high colon cancer, suggesting involvement of SIRT1 in gene silencing in this unique tumor subtype.

We analyzed a series of spindled and epithelioid cell nevi (Spitz) and primary cutaneous nodular melanomas to determine whether the expression of TRPM1 mRNA may be useful in distinguishing between Spitz nevi and nodular melanomas and to further examine the patterns of TRPM1 mRNA expression in cutaneous melanocytic proliferations. Formalin-fixed, paraffin-embedded tissues from 95 Spitz nevi and 33 nodular melanomas were analyzed for the expression of TRPM1 mRNA by in situ hybridization using (35)S-labeled riboprobes. Ubiquitous melanocytic expression of TRPM1 mRNA was observed in 56 of 95 (59%) Spitz nevi and 4 of 33 (12%) nodular melanomas. Diffusely scattered loss of TRPM1 mRNA was identified in 38 of 95 (40%) Spitz nevi and 2 of 33 (6%) nodular melanomas. Regional loss of the TRPM1 mRNA expression by a significant subset of dermal tumor cells or a complete absence of TRPM1 expression by the dermal tumor was identified in 27 of 33 (82%) nodular melanomas, but only 1 of 95 (1%) Spitz nevi. These findings suggest that the pattern of TRPM1 mRNA expression may be helpful in the differentiation of Spitz nevi and nodular melanomas. Of the 16 patients who experienced metastasis, 15 (94%) had primary tumors that displayed reduced MLSN mRNA expression by all or a part of the dermal tumor.

TI Cell polarity protein Lgl2 is lost or aberrantly localized in gastric dysplasia and adenocarcinoma: an immunohistochemical study SO MODERN PATHOLOGY LA English DT Article DE gastric; dysplasia; Lgl2; cell polarity; adenocarcinoma ID LETHAL GIANT LARVAE; EPITHELIAL DYSPLASIA; TUMOR SUPPRESSORS; DROSOPHILA; CANCER; COMPLEX; APKC; CLASSIFICATION; ACTIVATION; HUGL-1 AB The diagnosis of gastric epithelial dysplasia, a precursor lesion of gastric adenocarcinoma, is hindered by interobserver variability and by its resemblance to regenerative changes. Loss of cell polarity, a histological feature of gastric epithelial dysplasia, may be difficult to ascertain, especially in the setting of inflammation or injury. A biomarker of cell polarity could be useful in diagnosis of dysplasia, but has not been reported. The Lethal giant larvae (lgl) gene controls apical-basal polarity of epithelial cells in Drosophila, and has properties of a tumor-suppressor gene. Two homologs, lgl1 and lgl2, are present in mammals and lgl2 mRNA is highly expressed in the stomach. The goal of our study was to test the hypothesis that Lgl2 protein expression and/or localization are disrupted in gastric epithelial dysplasia and adenocarcinoma. Routinely processed pathology specimens including 94 benign mucosae of digestive organs, in addition to 36 reactive gastropathy, 57 gastric epithelial dysplasia, and 77 gastric adenocarcinomas, were immunostained for Lgl2 protein. All normal, reactive, and chronically inflamed gastric epithelia showed basolateral Lgl2 staining. Normal esophageal, duodenal, colonic, biliary, and pancreatic duct mucosae, as well as gastric intestinal metaplasia, did not express Lgl2. All but one case each of gastric epithelial dysplasia and adenocarcinoma showed either complete loss of anti-Lgl2 immunoreactivity or diffuse, mostly weak, cytoplasmic staining. Complete loss of immunoreactivity was significantly more often observed in diffuse-type than in intestinal-type adenocarcinomas (79 vs 48%, respectively). Our data suggest that Lgl2 expression is either aberrantly localized or lost in gastric epithelial dysplasia and adenocarcinoma, whereas it is maintained in reactive gastric mucosa. We propose that Lgl2 may be a potential marker to rule out gastric epithelial dysplasia and adenocarcinoma in diagnostic specimens. However, the consistently negative anti-Lgl2 immunoreactivity seen in intestinal metaplasia does not allow differentiation of dysplasia from intestinal metaplasia with reactive change.

TI Topoisomerase II alpha Is Required for Embryonic Development and Liver Regeneration in Zebrafish SO MOLECULAR AND CELLULAR BIOLOGY LA English DT Article ID RNA-POLYMERASE-II; CELL-CYCLE; CHROMATIN TEMPLATES; DNA TOPOISOMERASES; NIH-3T3 CELLS; IN-VITRO; EXPRESSION; MUTANT; DECATENATION; INHIBITION AB Topoisomerases solve the topological problems encountered by DNA throughout the lifetime of a cell. Topoisomerase II alpha, which is highly conserved among eukaryotes, untangles replicated chromosomes during mitosis and is absolutely required for cell viability. A homozygous lethal mutant, can4, was identified in a screen to identify genes important for cell proliferation in zebrafish by utilizing an antibody against a mitosis-specific marker, phospho-histone H3. Mutant embryos have a decrease in the number of proliferating cells and display increases in DNA content and apoptosis, as well as mitotic spindle defects. Positional cloning revealed that the genetic defect underlying these phenotypes was the result of a mutation in the zebrafish topoisomerase II alpha (top2a) gene. top2a was found to be required for decatenation but not for condensation in embryonic mitoses. In addition to being required for development, top2a was found to be a haploinsufficient regulator of adult liver regrowth in zebrafish. Regeneration analysis of other adult tissues, including fins, revealed no heterozygous phenotype. Our results confirm a conserved role for TOP2A in vertebrates as well as a dose-sensitive requirement for top2a in adults.

In this study, we show that overactivation of Ras and many of its downstream effectors occurred in only a fraction of MPNST cell lines. RalA, however, was overactivated in all MPNST cells and tumor samples compared to nontransformed Schwann cells. Silencing Ral or inhibiting it with a dominant-negative Ral (Ral S28N) caused a significant reduction in proliferation, invasiveness, and in vivo tumorigenicity of MPNST cells. Silencing Ral also reduced the expression of epithelial mesenchymal transition markers. Expression of the NF1-GTPase-related domain (NF1-GRD) diminished the levels of Ral activation, implicating a role for neurofibromin in regulating RalA activation. NF1-GRD treatment caused a significant decrease in proliferation, invasiveness, and cell cycle progression, but cell death increased. We propose Ral overactivation as a novel cell signaling abnormality in MPNST that leads to important biological outcomes with translational ramifications.

Autophagy in MM cell lines that express and secrete immunoglobulin and primary specimens was significantly increased by treatment with the endoplasmic reticulum stress-inducing agent thapsigargin, the mammalian target of rapamycin inhibitor rapamycin, and the proteasome inhibitor bortezomib. Inhibition of basal autophagy in these cell lines and primary cells by use of the inhibitors 3-methyladenine and chloroquine resulted in a cytotoxic effect that was associated with enhanced apoptosis. Use of small interfering RNA to knock down expression of beclin-1, a key protein required for autophagy, also inhibited viable recovery of MM cells. Because the data suggested that autophagy protected MM cell viability, we predicted that autophagy inhibitors would synergize with bortezomib for enhanced antimyeloma effects. However, the combination of these drugs resulted in an antagonistic response. In contrast, the autophagy inhibitor 3-methyladenine did synergize with thapsigargin for an enhanced cytotoxic response. These data suggest that autophagy inhibitors have therapeutic potential in myeloma but caution against combining such drugs with bortezomib.

In addition, LSDs may result from mutations in genes not yet implicated in disease. Thus, there are individuals that are diagnosed with apparent LSD based upon clinical criteria where the gene defect remains elusive. The objective of this study was to determine whether comparative proteomics approaches could provide useful insights into such cases. Most LSDs arise from mutations in genes encoding lysosomal proteins that contain mannose 6-phosphate, a carbohydrate modification that acts as a signal for intracellular targeting to the lysosome. We purified mannose 6-phosphorylated proteins by affinity chromatography and estimated relative abundance of individual proteins in the mixture by spectral counting of peptides detected by tandem mass spectrometry. Our rationale was that proteins that are decreased or absent in patients compared with controls could represent candidates for the primary defect, directing biochemical or genetics studies. On a survey of brain autopsy specimens from 23 patients with either confirmed or possible lysosomal disease, this approach identified or validated the genetic basis for disease in eight cases. These results indicate that this protein expression approach is useful for identifying defects in cases of undiagnosed lysosomal disease, and we demonstrated that it can be used with more accessible patient samples, e. g. cultured cells. Furthermore this approach was instrumental in the identification or validation of mutations in two lysosomal proteins, CLN5 and sulfamidase, in the adult form of neuronal ceroid lipofuscinosis.

This cornerstone of reproductive biology was challenged 5 years ago by a study reporting on the presence of mitotically-active germ cells in juvenile and adult mouse ovaries. Additional findings presented in this study and others that followed further suggested that mammals retain the capacity to generate oocytes during adulthood; however, isolation of oocyte-producing germline stem cells (GSC) as unequivocal proof of their existence remained elusive. This piece of information now appears to have been provided by Ji Wu and colleagues. In addition to showing that proliferative germ cells resembling male spermatogonial stem cells can be purified from neonatal or adult mouse ovaries and maintained in vitro for months, transplantation studies demonstrated that these cells generate oocytes in ovaries of chemotherapy-sterilized recipients that fertilize and produce viable offspring. Although these findings do not establish that oogenesis occurs in adult females under physiological conditions, they strongly support the existence of GSC in adult mouse ovaries. If equivalent cells can be found in human ovaries, stem cell-based rejuvenation of the oocyte reserve in ovaries on the verge of failure may one day be realized.

CA Inflammation Host Response Injury TI A Genomic Score Prognostic of Outcome in Trauma Patients SO MOLECULAR MEDICINE LA English DT Article ID MULTIPLE ORGAN FAILURE; INJURY SEVERITY SCORE; APACHE-II; VARIABILITY; PREDICTORS; DISEASE; SYSTEM; CARE AB Traumatic injuries frequently lead to infection, organ failure, and death. Health care providers rely on several injury scoring systems to quantify the extent of injury and to help predict clinical outcome. Physiological, anatomical, and clinical laboratory analytic scoring systems (Acute Physiology and Chronic Health Evaluation (APACHE), Injury Severity Score (ISS)) are utilized, with limited success, to predict outcome following injury. The recent development of techniques for measuring the expression level of all of a person's genes simultaneously may make it possible to develop an injury scoring system based on the degree of gene activation. We hypothesized that a peripheral blood leukocyte gene expression score could predict outcome, including multiple organ failure, following severe blunt trauma. To test such a scoring system, we measured gene expression of peripheral blood leukocytes from patients within 12 h of traumatic injury. cRNA derived from whole blood leukocytes obtained within 12 h of injury provided gene expression data for the entire genome that were used to create a composite gene expression score for each patient. Total blood leukocytes were chosen because they are active during inflammation, which is reflective of poor outcome. The gene expression score combines the activation levels of all the genes into a single number which compares the patient's gene expression to the average gene expression in uninjured volunteers. Expression profiles from healthy volunteers were averaged to create a reference gene expression profile which was used to compute a difference from reference (DFR) score for each patient. This score described the overall genomic response of patients within the first 12 h following severe blunt trauma. Regression models were used to compare the association of the DFR, APACHE, and ISS scores with outcome. We hypothesized that patients with a total gene response more different from uninjured volunteers would tend to have poorer outcome than those more similar. Our data show that for measures of poor outcome, such as infections, organ failures, and length of hospital stay, this is correct. DFR scores were associated significantly with adverse outcome, including multiple organ failure, duration of ventilation, length of hospital stay, and infection rate. The association remained significant after adjustment for injury severity as measured by APACHE or ISS. A single score representing changes in gene expression in peripheral blood leukocytes within hours of severe blunt injury is associated with adverse clinical outcomes that develop later in the hospital course. Assessment of genome-wide gene expression provides useful clinical information that is different from that provided by currently utilized anatomic or physiologic scores.

We studied three separate human populations: group 1, infertility patients (Long Island, NY, USA); group 2, artificial insemination donors (AID) (Rochester, NY, USA); and group 3, general population volunteers (Rochester, NY, USA). Information about confounding factors was collected by questionnaire. Seminal plasma cadmium did not correlate with blood cadmium (Spearman correlation, n = 91, r = -0.092, P = 0.386, NS). Both blood and seminal plasma cadmium were significantly higher among infertility patients than the other subjects studied (for example, median seminal plasma cadmium was 0.282 mu g/L in infertility patients versus 0.091 mu g/L in AID and 0.092 mu g/L in general population volunteers; Kruskal-Wallis test, P < 0.001). The percentage of motile sperm and sperm concentration correlated inversely with seminal plasma cadmium among the infertility patients (r = -0.201, P < 0.036 and r = -0.189, Pc 0.05, respectively), but not in the other two groups. Age (among infertility patients) was the only positive confounder correlating with seminal plasma cadmium. To validate our human findings in an animal model, we chronically exposed adolescent male Wistar rats to low-moderate cadmium in drinking water. Though otherwise healthy the rats exhibited decreases in epididymal sperm count and sperm motility associated with cadmium dose and time of exposure. Our human and rat study results are consistent with the hypothesis that environmental cadmium exposures may contribute significantly to reduced human male sperm concentration and sperm motility.

It has electromyographic features of spontaneous, continuous, irregularly occurring doublets, or multiplets of motor unit potential discharges. Neuromyotonia is characterized by both myokymic and neuromyotonic discharges. To our knowledge, this is the first report in the literature to assess the sensitivity of skeletal muscle to a nondepolarizing muscle relaxant drug, rocuronium, in a woman with acquired neuromyotonia. She had a past medical history notable for prolonged postoperative paralysis following anesthesia. The patient showed increased sensitivity to the neuromuscular effects of rocuronium. This increase in sensitivity may be explained by downregulation of acetylcholine receptors in response to chronic high agonist (acetylcholine) concentrations. If patients with neuromyotonia receive anesthesia, we recommend that smaller doses of a nondepolarizing muscle relaxant be administered, accompanied by monitoring of neuromuscular function, so as to provide optimal muscle relaxation while avoiding overdose and prolonged postoperative recovery.

TI Multi-site assessment of the precision and reproducibility of multiple reaction monitoring-based measurements of proteins in plasma SO NATURE BIOTECHNOLOGY LA English DT Article ID MASS-SPECTROMETRIC QUANTITATION; ABSOLUTE QUANTIFICATION; ISOTOPE-DILUTION; BIOMARKER DISCOVERY; PEPTIDE STANDARDS; SERUM; ASSAYS; LC/MS/MS; PROTEOME; LIMITS AB Verification of candidate biomarkers relies upon specific, quantitative assays optimized for selective detection of target proteins, and is increasingly viewed as a critical step in the discovery pipeline that bridges unbiased biomarker discovery to preclinical validation. Although individual laboratories have demonstrated that multiple reaction monitoring (MRM) coupled with isotope dilution mass spectrometry can quantify candidate protein biomarkers in plasma, reproducibility and transferability of these assays between laboratories have not been demonstrated. We describe a multilaboratory study to assess reproducibility, recovery, linear dynamic range and limits of detection and quantification of multiplexed, MRM-based assays, conducted by NCI-CPTAC. Using common materials and standardized protocols, we demonstrate that these assays can be highly reproducible within and across laboratories and instrument platforms, and are sensitive to low lg/ml protein concentrations in unfractionated plasma. We provide data and benchmarks against which individual laboratories can compare their performance and evaluate new technologies for biomarker verification in plasma.

Replication in an independent set of 2,215 subjects with MS and 2,116 control subjects validates new MS susceptibility loci at TNFRSF1A (combined P = 1.59 x 10(-11)), IRF8 (P = 3.73 x 10(-9)) and CD6 (P = 3.79 x 10(-9)). TNFRSF1A harbors two independent susceptibility alleles: rs1800693 is a common variant with modest effect (odds ratio 1.2), whereas rs4149584 is a nonsynonymous coding polymorphism of low frequency but with stronger effect (allele frequency 0.02; odds ratio 1.6). We also report that the susceptibility allele near IRF8, which encodes a transcription factor known to function in type I interferon signaling, is associated with higher mRNA expression of interferon-response pathway genes in subjects with MS.

TI Lin28 promotes transformation and is associated with advanced human malignancies SO NATURE GENETICS LA English DT Article ID HUMAN HEPATOCELLULAR-CARCINOMA; EPITHELIAL OVARIAN-CANCER; LUNG-CANCER; WILMS-TUMOR; MICRORNA EXPRESSION; GENE-EXPRESSION; CELL-DIFFERENTIATION; STEM-CELLS; LET-7; METASTASIS AB Multiple members of the let-7 family of miRNAs are often repressed in human cancers(1,2), thereby promoting oncogenesis by derepressing targets such as HMGA2, K-Ras and c-Myc(3,4). However, the mechanism by which let-7 miRNAs are coordinately repressed is unclear. The RNA-binding proteins LIN28 and LIN28B block let-7 precursors from being processed to mature nmiRNAs(5-8), suggesting that their overexpression might promote malignancy through repression of let-7. Here we show that LIN28 and LIN28B are overexpressed in primary human tumors and human cancer cell lines (overall frequency B15%), and that overexpression is linked to repression of let-7 family miRNAs and derepression of let-7 targets. LIN28 and LIN28b facilitate cellular transformation in vitro, and overexpression is associated with advanced disease across multiple tumor types. Our work provides a mechanism for the coordinate repression of let-7 miRNAs observed in a subset of human cancers, and associates activation of LIN28 and LIN28B with poor clinical prognosis.

We identify basophils as a dominant cell population that coexpressed major histocompatibility complex class II and interleukin 4 message after helminth infection. Basophilia was promoted by thymic stromal lymphopoietin, and depletion of basophils impaired immunity to helminth infection. Basophils promoted antigen-specific CD4(+) T cell proliferation and interleukin 4 production in vitro, and transfer of basophils augmented the population expansion of helminth-responsive CD4(+) T cells in vivo. Collectively, our studies suggest that major histocompatibility complex class II-dependent interactions between basophils and CD4(+) T cells promote T helper type 2 cytokine responses and immunity to helminth infection.

However, because of intense light scattering, most organisms and tissues remain inaccessible to current fluorescence microscopy techniques at depths beyond several hundred micrometres. We describe a multispectral opto-acoustic tomography technique capable of high-resolution visualization of fluorescent proteins deep within highly light-scattering living organisms. The method uses multiwavelength illumination over multiple projections combined with selective-plane opto-acoustic detection for artifact-free data collection. Accurate image reconstruction is enabled by making use of wavelength-dependent light propagation models in tissue. By performing whole-body imaging of two biologically important and optically diffuse model organisms, Drosophila melanogaster pupae and adult zebrafish, we demonstrate the facility to resolve tissue-specific expression of eGFP and mCherrry fluorescent proteins for precise morphological and functional observations in vivo.

C. difficile infections are also emerging in the community and in animals used for food, and are no longer viewed simply as unpleasant complications that follow antibiotic therapy. Since 2001, the prevalence and severity of C. difficile infection has increased significantly, which has led to increased research interest and the discovery of new virulence factors, and has expanded and focused the development of new treatment and prevention regimens. This Review summarizes the recent epidemiological changes in C. difficile infection, our current knowledge of C. difficile virulence factors and the clinical outcomes of C. difficile infection.

Understanding UP-DOWN state dynamics is important for understanding how these circuits represent and transmit information in the brain. To date, limited work has been done on characterizing the stochastic properties of UP-DOWN state dynamics. We present a set of Markov and semi-Markov discrete-and continuous-time probability models for estimating UP and DOWN states from multiunit neural spiking activity. We model multiunit neural spiking activity as a stochastic point process, modulated by the hidden (UP and DOWN) states and the ensemble spiking history. We estimate jointly the hidden states and the model parameters by maximum likelihood using an expectation-maximization (EM) algorithm and a Monte Carlo EM algorithm that uses reversible-jump Markov chain Monte Carlo sampling in the E-step. We apply our models and algorithms in the analysis of both simulated multiunit spiking activity and actual multiunit spiking activity recorded from primary somatosensory cortex in a behaving rat during slow-wave sleep. Our approach provides a statistical characterization of UP-DOWN state dynamics that can serve as a basis for verifying and refining mechanistic descriptions of this process.

However, in health, A beta degradation is mediated by extracellular metalloproteinases, neprilysin, insulin degrading enzyme (IDE) and matrix metalloproteinases. We investigated the relationship between levels of A beta and biological metals in CSF. We assayed CSF copper, zinc, other metals and A beta 42 in ventricular autopsy samples of Japanese American men (N=131) from the population-based Honolulu Asia Aging Study. There was a significant inverse correlation of CSF A beta 42 with copper, zinc, iron, manganese and chromium. The association was particularly strong in the subgroup with high levels of both zinc and copper. Selenium and aluminum levels were not associated to CSF A beta 42. In vitro, the degradation of synthetic A beta substrate added to CSF was markedly accelerated by low levels (2 mu M) of exogenous zinc and copper. While excessive interaction with copper and zinc may induce neocortical A beta precipitation in AD, soluble A beta degradation is normally promoted by physiological copper and zinc concentrations.

Previously, a number of magnetic resonance microscopy (MRM) studies have successfully established brain atlases, revealing genotypic traits of several commonly used mouse strains. In such Studies, MR contrast agents, mainly gadolinium (Gd) based, were often used to reduce acquisition time and improve signal-to-noise ratio (SNR). In this paper, we intended to extend the utility of contrast agents for MRM applications. Using Gd-DTPA and MnCl(2), we exploited the potential use of MR Contrast agents to manipulate image contrast by drawing upon the multiple relaxation mechanisms and tissue-dependent staining properties characteristic of each contrast agent. We quantified r(1) and r(2) of GdDTPA and MnCl(2) in both aqueous solution and brain tissue and demonstrated the presence of divergent relaxation mechanisms between solution and tissue for each contrast agent. Further analyses using nuclear magnetic resonance dispersion (NMRD) of Mn(2+) in ex vivo tissue strongly suggested macromolecule binding of Mn(2+), leading to increased T(1) relaxation. Moreover, inductively coupled plasma (ICP) mass spectroscopy revealed that MnCl(2) had higher tissue affinity than Gd-DTPA. As a result, multiple regions of the brain stained by the two agents exhibited different image contrasts. Our results show that differential MRM staining can be achieved using multiple MR contrast agents, revealing detailed cytoarchitecture, and may ultimately offer a window for investigating new techniques by which to understand biophysical MR relaxation mechanisms and perhaps to Visualize tissue anomalies even at the molecular level.

Previous fMRI studies have shown a habituation effect in the hemodynamic blood oxygen level-dependent (BOLD) response for stimulation periods longer than 2 s. With DOI and MEG we can test whether this effect in hemodynamic response can be accounted for by a habituation effect in the neural response. Our experimental results show that the habituation effect in the hemodynamic response is stronger than that in the earliest cortical neural response (N20). Using a linear convolution model to predict hemodynamic responses we found that including late neural components (>= 30 ms) improves the prediction of the hemoglobin response. This finding suggests that in addition to the initial evoked-response deflections related to the talamic afferent input, later cortical activity is needed to predict the hemodynamic response.

We tested a novel pulse sequence to determine whether 3 T MRI spin-spin relaxometry detected damage in NAWM of MS patients (n = 13) vs. age-matched normal controls [(NL) (n = 11)]. Baseline characteristics of the MS group were: age (mean +/- SD) 42.5 +/- 5.4 (range 33-51 years), disease duration 9.0 +/- 6.4 (range 1-22 years), Expanded Disability Status Scale score 2.5 +/- 1.7 (range 1-6.5). Brain MRI measures, obtained at 3 T, included global and regional NAWM transverse relaxation rate [R2 (=1/T2)], derived from 3D fast spin-echo T2 prepared images, and global white matter volume fraction derived from SPGR images. The regional NAWM areas investigated were the frontal lobe, parietal lobe, and the genu and splenium of the corpus callosum. Mean NAWM R2 was lower (indicating T2 prolongation) in MS than NL, in the whole brain (p = 0.00047). frontal NAWM (p = 0.00015), parietal NAWM (p = 0.0069) and callosal genu (p = 0.0019). Similarly, R2 histogram peak position was lower in NAWM in MS than NL in the whole brain (p = 0.019). However, the normalized WM Volume fractions were similar in both MS and NL (p > 0.1). This pilot study suggests that a novel 3D fast spin-echo pulse sequence at 3 T, used to derive R2 relaxation maps, can detect tissue damage in the global and regional cerebral NAWM of MS patients that is missed by conventional lesion and atrophy measures. Such findings may represent demyelination, inflammation, glial proliferation and axonal loss. (C) 2009 Elsevier Inc. All rights reserved.

Acute intracranial hypertension resulting from elevation of intracranial pressure is a medical emergency requiring prompt diagnosis and management. Appropriate and timely management strategies result in better patient outcome in an otherwise severely debilitating or fatal disease process. Review Summary: The clinical manifestation and principles of management of acute intracranial hypertension are discussed and reviewed. Acute treatment protocols are presented in an algorithm-based format aimed at utilizing the current available management strategies and suggested therapeutic goals. Individualization of specific therapeutic modalities is emphasized to optimize the clinical outcome. Conclusions: Clinicians treating patients with acute brain injury should be familiar with the principles of management of increased intracranial pressure. Since acute intracranial hypertension is a potentially reversible condition, high index of suspicion, and low threshold for diagnostic and therapeutic strategies will improve patient care.

Therefore, we tested whether adenosine can inhibit exocytosis from isolated cone photoreceptors. Simultaneous measurements of membrane exocytosis and Ca(2+) were made from cones using the activity-dependent dye, Synaptored-C2, and the Ca(2+) indicator dye, Fluo-4. Adenosine suppressed exocytosis in cones, indicating that transmitter release is also reduced from cone terminals, and further supports an inhibitory mechanism for modulating transmitter release onto second-order neurons. Furthermore, this raises the possibility that adenosine might be neuroprotective for photoreceptors and second-order neurons by suppressing Ca(2+) levels in cones and reducing exocytosis of L-glutamate, respectively.

Eight, normal, right-handed participants discriminated between two patterns presented on the palm. Latencies of neural activity were determined from stimulus contact with the palm. Early cortical activation moved from sensorimotor cortex (SM1) to secondary somatosensory cortex (SII), Broca's area (BA), and superior parietal cortex by 65 ms. It continued bilaterally to temporal and frontal poles by 290 ms. Subtraction of nonattended from attended conditions removed primarily the early contralateral sensory components. There was some indication of a preferred order of sensory processing that may express and optimize hemispheric computational specializations. Results indicate similar functional organizations for tactile and visual pattern recognition. NeuroReport 20:941-945 (C) 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Several targets have been identified for ablation or stimulation based on their anatomical location and presumed function. Areas such as the subthalamic nucleus, globus pallidus, and thalamus, for example, are believed to play a key role in motor control and execution, and they are commonly used in the treatment of motor disorders. Limbic structures such as the cingulate cortex and ventral striatum, believed to be important in motivation, emotion, and higher cognition, have also been targeted for treatment of a number of psychiatric disorders. In all of these settings, DBS is largely aimed at addressing the deleterious aspects of these diseases. In Parkinson disease, for example, DBS has been used to reduce rigidity and tremor, whereas in obsessive-compulsive disorder it has been used to limit compulsive behavior. More recently, however, attention has also turned to the potential use of DBS for enhancing or improving otherwise nonpathological aspects of cognitive function. This review explores the potential role of DBS in augmenting memory formation and recall, and the authors discuss recent studies and future trends in this emerging field.

The visual pathway, however, as a predominantly central structure, is largely spared in these cases. It is thus widely thought that a device-based prosthetic approach to restoration of visual function will be effective and will enjoy similar success as cochlear implants have for restoration of auditory function. In this article the authors review the potential locations for stimulation electrode placement for visual prostheses, assessing the anatomical and functional advantages and disadvantages of each. Of particular interest to the neurosurgical community is placement of deep brain stimulating electrodes in thalamic structures that has shown substantial promise in an animal model. The theory of operation of visual prostheses is discussed, along with a review of the current state of knowledge. Finally, the visual prosthesis is proposed as a model for a general high-fidelity machine-brain interface.

Identification and characterization of endogenous neural stem cells (NSCs), especially those in the adult human brain, have inspired new ideas for selectively targeting and destroying malignant gliomas. Gliomas consist of a heterogeneous population of cells, and some of these cells have characteristics of cancer stem cells. These brain tumor stem cells (BTSCs) share certain characteristics with normal NSCs. It is still unclear, however, whether malignant gliomas in human patients originate from these aberrant BTSCs. Nonetheless, the cellular and molecular similarities between BTSCs and normal NSCs suggest a common research landscape underlying both normal and cancer stem cell biology, wherein findings of one field are relevant to the other. Furthermore, the natural tropism of NSCs to gliomas has generated the idea that modified NSCs can deliver modified genes to selectively destroy malignant brain tumor cells, and even BTSCs, while leaving healthy surrounding neurons intact. These studies and others on the basic biology of both BTSCs and NSCs will be crucial to expanding our treatment strategies for malignant gliomas.

Early clinical trials suggest that antiangiogenic drugs, which target the blood vessels of these highly angiogenic tumors, may have clinical benefit in GBM patients. Antiangiogenic agents have potent antiedema and steroid-sparing effects in patients, and emerging data suggest that these drugs may modestly improve progression-free survival. Although these early results are encouraging, several issues arise regarding the use and efficacy of these agents. Interpretation of the radiographic changes that occur after treatment with antiangiogenic agents presents a major challenge. Still lacking are reliable radiographic and biologic markers that can predict which patients will benefit from treatment and that accurately indicate response and progression during therapy. In addition, most patients treated with antiangiogenic drugs eventually progress, and the mechanisms by which tumors escape from therapy are only beginning to be understood. Larger prospective trials that incorporate correlative biomarker studies will be required to address these challenges. Here, we summarize the clinical experience with antiangiogenic therapy in patients with malignant gliomas (MG), review the major issues concerning the use and development of these agents, and discuss strategies that may build upon the initial gains observed with antiangiogenic agents.

Venomous animals include scorpions, snakes, bees, wasps, frogs and numerous animals living in the sea such as the stonefish, snail, jellyfish, hydra and more. Interestingly, proteins that share a common scaffold with animal toxins also exist in non-venomous species. However, due to their short length and primary sequence diversity, these, toxin-like proteins remain undetected by classical search engines and genome annotation tools. We construct a toxin classification machine and web server called ClanTox (Classifier of Animal Toxins) that is based on the extraction of sequence-driven features from the primary protein sequence followed by the application of a classification system trained on known animal toxins. For a given input list of sequences, from venomous or non-venomous settings, the ClanTox system predicts whether each sequence is toxin-like. ClanTox provides a ranked list of positively predicted candidates according to statistical confidence. For each protein, additional information is presented including the presence of a signal peptide, the number of cysteine residues and the associated functional annotations. ClanTox is a discovery-prediction tool for a relatively overlooked niche of toxin-like cell modulators, many of which are therapeutic agent candidates. The ClanTox web server is freely accessible at http://www.clantox.cs.huji.ac.il.

Harris, Jay R. TI Effective Local Therapy and Long-Term Survival in Breast Cancer SO ONCOLOGY-NEW YORK LA English DT Article AB The causal link between local control and long-term survival in breast cancer has become clearer over the past few years. Although the prevalence of breast cancer is high, there has been a steady decline in breast cancer mortality since the early 1990s. Improvements in breast cancer-specific mortality are the result of greater emphasis on cancer screening and improved treatment modalities, principally the development of effective adjuvant systemic therapy. Adjuvant radiation therapy (RT) substantially reduces local recurrence rates, and this reduction is even greater when combined with systemic therapy. Randomized controlled trials and meta-analyses have shown that reducing local recurrence improves overall long-term survival following both mastectomy and breast-conserving therapy. Clinical and translational research has begun to shed light on new prognostic and predictive markers that can assist in the assessment of an individual patient's risk of local recurrence without RT and the likelihood of a survival benefit with RT. The ability to appropriately tailor therapy to reduce local recurrence rates is vital toward continuing the decline in breast cancer mortality.

However, it has yet to equal a dilated fundus examination or seven Early Treatment Diabetic Retinopathy Study field 35-mm photography. The authors therefore attempted to enhance efficacy and validity by adding two low-cost steps to the nonmydriatic digital image evaluation. PATIENTS AND METHODS: The fundi of 145 consecutive patients with diabetes mellitus were evaluated for diabetic retinopathy using two different nonmydriatic reading techniques: creating a red-free view (using digital filters) and looking at a stereo pair of each field taken. These methods were each compared to a mydriatic fundus examination. RESULTS: although the first technique yielded views with sensitivities and specificities similar to what exists in the literature using this same technique, enhancing these photographs (second technique) yielded a statistically significant increase in sensitivity and specificity (P < .005). CONCLUSION: The authors recommend using both low-cost steps when screening for diabetic retinopathy through nonmydriatic digital color imaging.

TI Feasibility of in vivo imaging of fluorescent proteins using lifetime contrast SO OPTICS LETTERS LA English DT Article ID TOMOGRAPHY; MICROSCOPY; DOMAIN; CELLS AB We show that fluorescence lifetime is a powerful contrast mechanism that can enhance the whole-body imaging of fluorescent proteins (FPs), in the presence of background tissue autofluorescence (AF). The nonexponential AF decay is characterized from time-domain (TD) measurements on multiple nude mice and separated from the FP fluorescence using a linear fit to a priori basis functions. We illustrate this approach using an orthotopic mouse tumor model of breast adenocarcinoma. We also report that four commonly used FPs show distinct lifetimes, indicating their suitability for in vivo lifetime multiplexing. These results suggest the potential for exploiting fluorescence lifetime for imaging Fps for a variety of whole-body small-animal imaging applications.

Methods: Partial discs of TMJ in mice were removed by microsurgery. Histology was performed to characterize articular cartilages from the TMJ of mice. The morphology of the articular cartilages was evaluated using a modified Mankin scoring system. Immunohistostaining was carried out to examine the expression of discoidin domain receptor 2 (Ddr2), a type II collagen receptor, matrix metalloproteinase-13 (Mmp-13), and Mmp-derived type II collagen fragments in the articular cartilage of condyles from the mouse TMJ. Results: Articular cartilage degeneration was seen in the mouse TMJ post-discectomy, including increased proteoglycan staining in the extracellular matrix at 4 weeks, the appearance of chondrocyte clusters at 8 weeks, reduced proteoglycan staining and fibrillation at 12 weeks and the loss of articular cartilage at 16 weeks. Increased immunostaining for Ddr2, Mmp-13, and Mmp-derived type 11 collagen fragments was detected. Conclusion: Results indicate that partial discectomy induces early-onset OA in mouse TMJ and that increased expression of Mmp-13, likely due to the elevated expression of Ddr2, may be one of the factors responsible for the early-onset OA in mouse TMJ.

STUDY DESIGN: Case series with chart review. SUBJECTS AND METHODS: Sixty-seven patients underwent cVEMP testing. We correlated mean tone burst cVEMP amplitude and threshold data with temporal bone CT findings. Patients were excluded for Meniere's disease, middle ear disease. or otologic surgery. RESULTS: Superior canal dehiscence patients had higher mean cVEMP amplitudes (SCDS 173.8 mu V vs non-SCDS 69.7 mu V, P = 0.031) and lower mean thresholds (SCDS 72.8 dB nHL vs non-SCDS 80.9 dB nHL) at 500 Hz. CONCLUSION: Patients with SCDS have larger amplitudes and lower thresholds on cVEMP testing at 500 Hz. This study supports the utility of tone burst cVEMPs for the evaluation of SCDS and is one of few large single-center studies to establish normative data.

Metson, Ralph TI Revision endoscopic orbital decompression in the management of Graves' orbitopathy SO OTOLARYNGOLOGY-HEAD AND NECK SURGERY LA English DT Article ID OPTIC-NERVE DECOMPRESSION; OPHTHALMOPATHY; REACTIVATION AB OBJECTIVE: Endoscopic orbital decompression has proved to be an effective treatment for Graves' orbitopathy. In select patients, however, persistent or recurrent orbital symptoms necessitate additional therapy. The objective of this study is to determine the safety and effectiveness of revision endoscopic orbital decompression in patients with refractory Graves' orbitopathy. STUDY DESIGN: Case-control series. SETTING: Academic medical center. METHODS: The study population consisted of 10 patients with Graves' orbitopathy who underwent 13 revision endoscopic orbital decompressions (three bilateral cases) between 1991 and 2008. Outcome measures, including reduction in proptosis, improvement in visual acuity, and complication rates, were compared with a control cohort of 10 consecutive patients (16 orbits) who underwent primary endoscopic decompression during the same time period. RESULTS: Indications for revision decompression included exposure keratopathy (n = 8, 62%), optic neuropathy (n = 3, 23%), and gaze restriction (n = 2, 15%). There were no intraoperative complications. Mean reduction in proptosis was 1.4 mm less for patients who underwent revision decompression compared with primary cases (mean decompression 3.6 +/- 1.0 mm vs 5.0 +/- 2.1 mm, respectively), although this difference was not statistically significant (P = 0.13). Visual acuity improved in 62 percent of revision cases, compared with 20 percent of primary cases (P = 0.09). Rates for postoperative complications, which included sinusitis and frontal mucocele formation, were also similar between revision and primary decompression groups (38% vs 13% respectively, P = 0.17). CONCLUSIONS: This report is the first to describe the endoscopic technique for revision orbital decompression. It appears to be a safe and effective procedure for the treatment of refractory orbitopathy in patients with Graves' disease.

TI Bilateral simultaneous free gracilis muscle transfer: A realistic option in management of bilateral facial paralysis SO OTOLARYNGOLOGY-HEAD AND NECK SURGERY LA English DT Article AB OBJECTIVES: Bilateral facial paralysis patients have oral incompetence, poor articulation, and dental caries. This problem is frequently addressed by performing staged gracilis transplants without specific oral sphincter reconstruction. The purpose of this study is to describe the technique of bilateral simultaneous free gracilis muscle transfer with oral sphincter reconstruction, for one-stage facial reanimation in patients with bilateral facial paralysis. STUDY DESIGN: Case series. METHODS/RESULTS: One-stage bilateral gracilis transfer was performed in three patients with bilateral facial paralysis. Muscle transplants produced a meaningful smile in all transferred muscles. All patients reported improved speech and decreased drooling. CONCLUSIONS: Bilateral gracilis transplants with reconstruction of the oral commissure is a realistic option in management of the bilaterally paralyzed face. In this small series, it appears to improve oral competence, restore smiling, and contribute favorably to lower lip support. This technique has been made more feasible because the operative time for free tissue transfer has continuously declined with the use of two-team surgery, improved microsurgical techniques, and the advent of venous coupling devices.

Methods: An infection was established in a rabbit model by creating bilateral subcutaneous implant pockets, into which a pacing device with or without AIGIS(RX)(TM) was placed. The incisions were closed, and a defined dose of bacteria was infused into each implant pocket. After 7 days, devices were explanted and sampled for viable bacteria by swabbing and sonication. Results: Initial studies evaluated the ability of the AIGIS(RX) pouch to reduce Staphylococcus epidermidis (S. epi) infection in this model using clinical and quantitative microbial endpoints. Results demonstrate S. epi infection in all control samples, while no pathogens were recovered from samples with the AIGIS(RX)(TM) pouch. Systemic antibiotic levels were undetectable. Additional studies tested the efficacy of the AIGIS(RX)(TM) pouch with additional bacterial strains, Staphylococcus capitis, Escherichia coli, and Acinetobacter Baumannii. In each case, the device and implant pocket with the AIGIS(RX)(TM) pouch was free of any signs of infection. An assessment of biofilm produced by Acinetobacter demonstrated the elimination of biofilm formation on the implanted device. Conclusion: These results demonstrate that in this animal model, the AIGIS(RX)(TM) device reduces the risk for infection of viable pathogens within implant pockets. (PACE 2009; 32:898-907).

Clinical data, indications for ILR, interrogation reports, and further management strategies were collected in all 86 patients who received ILR from June 1999 to April 2008 at the University of Iowa Hospitals and Clinics. The indications for ILR were unexplained syncope (76%), palpitations (14%), and presyncope or dizziness (10%). Results: During a mean follow-up period of 10 +/- 7 months, 53 patients (62%) had recurrent symptoms after ILR placement with the mean time to recurrence of 12 +/- 17 weeks. Of these, an arrhythmic diagnosis was established in 12 patients (14%). Forty-one patients (48%) did not have any arrhythmia during their symptoms. These patients were discharged from the electrophysiology clinic. Thirty-three patients (38%) did not have any symptoms following ILR placement. Out of these, device was explanted in 10 patients, while the rest are still being followed. Conclusions: In patients with potentially arrhythmic symptoms, ILR plays an important role not only in diagnosing an arrhythmia, but also to rule out an arrhythmic cause. (PACE 2009; 32:908-912).

TI Predictors of Resolution of Aberrant Drug Behavior in Chronic Pain Patients Treated in a Structured Opioid Risk Management Program SO PAIN MEDICINE LA English DT Article DE Opioids; Chronic Pain; Aberrant Drug Behavior; Substance Abuse; Primary Care; Opioid Renewal Clinic ID PRIMARY-CARE PHYSICIANS; CHRONIC NONCANCER PAIN; SOCIAL SUPPORT; ABUSE; THERAPY; MISUSE; ADJUSTMENT; DEPENDENCE; ADDICTION; NETWORK AB Objective. To identify demographic and clinical predictors of the resolution of aberrant drug-related behaviors (ADRBs) in a group of patients referred to the Opioid Renewal Clinic (ORC) by their primary care providers (PCPs). ORC is a program supporting PCPs' use of opioids for chronic pain in patients perceived as at risk for opioid abuse or those with demonstrated ADRBs. Methods. A retrospective chart review was conducted for 195 consecutive subjects referred to the ORC from January 17, 2002 to August 27, 2004, for ADRBs. Binary logistic regression was employed to identify independent predictors of aberrant behavior outcome at 1 year. Results. Of the 195 referred, 45.6% (N = 89) resolved their ADRB at 1 year. Other outcomes, classified as nonresolution of ADRB, self-discharged or discharged by the ORC for inability to adhere to the opioid treatment agreement (N = 86, 44.1%) and acceptance of referral for addiction treatment (N = 20, 10.2%). A history of cocaine abuse increased the odds of failing the program by five times (odds ratio [OR] = 4.97, P = 0.001). Each additional pain diagnosis reduced the odds of failure by 16% (OR = 0.837, P = 0.008). When compared with singles, married individuals were 62% less likely to fail the ORC program (OR = 0.38, P = 0.028). Conclusions. Nearly half of the patients resolved their aberrant behavior within the ORC. Patients with cocaine abuse were at higher risk for failure, suggesting a need for further research into safe and effective ways to manage pain in this complex subset of patients. Aberrant behaviors tended to resolve in patients with multiple pain locations, possibly because of their desire for relief.

Objective: To develop evidence-based clinical practice guidelines for interventional techniques in the diagnosis and treatment of chronic spinal pain. Design: Systematic assessment of the literature. Methods: Strength of evidence was assessed by the U.S. Preventive Services Task Force (USPSTF) criteria utilizing 5 levels of evidence ranging from Level I to III with 3 subcategories in Level II. Outcomes: Short-term pain relief was defined as relief lasting at least 6 months and long-term relief was defined as longer than 6 months, except for intradiscal therapies, mechanical disc decompression, spinal cord stimulation and intrathecal infusion systems, wherein up to one year relief was considered as short-term. Results: The indicated evidence for accuracy of diagnostic facet joint nerve blocks is Level I or 111 in the diagnosis of lumbar, thoracic, and cervical facet joint pain. The evidence for lumbar and cervical provocation discography and sacroiliac joint injections is Level II-2, whereas it is Level II-3 for thoracic provocation discography The indicated evidence for therapeutic interventions is Level I for caudal epidural steroid injections in managing disc herniation or radiculitis, and discogenic pain without disc herniation or radiculitis. The evidence is Level I or II-1 for percutaneous adhesiolysis in management of pain secondary to post-lumbar surgery syndrome. The evidence is Level II-1 or II-2 for therapeutic cervical, thoracic, and lumbar facet joint nerve blocks; for caudal epidural injections in managing pain of post-lumbar surgery syndrome, and lumbar spinal stenosis, for cervical interlaminar epidural injections in managing cervical pain (Level II-1); for lumbar transforaminal epidural injections; and spinal cord stimulation for post-lumbar surgery syndrome. The indicated evidence for intradiscal electrothermal therapy (IDET), mechanical disc decompression with automated percutaneous lumbar discectomy (APLD), and percutaneous lumbar laser discectomy (PLDD) is Level II-2. Limitations: The limitations of these guidelines include a continued paucity of the literature, lack of updates, and conflicts in preparation of systematic reviews and guidelines by various organizations. Conclusion: The indicated evidence for diagnostic and therapeutic interventions is variable from Level I to III. These guidelines include the evaluation of evidence for diagnostic and therapeutic procedures in managing chronic spinal pain and recommendations for managing spinal pain, However, these guidelines do not constitute inflexible treatment recommendations. Further, these guidelines also do not represent "standard of care." C1 [Manchikanti, Laxmaiah; Fellows, Bert] Pain Management Ctr Paducah, Paducah, KY USA.

Chronic pain has been defined in many ways. Chronic pain syndrome is a separate entity from chronic pain. Chronic pain is defined as, "pain that persists 6 months after an injury and beyond the usual course of an acute disease or a reasonable time for a comparable injury to heal, that is associated with chronic pathologic processes that cause continuous or intermittent pain for months or years, that may continue in the presence or absence of demonstrable pathologies; may not be amenable to routine pain control methods; and healing may never occur." In contrast, chronic pain syndrome has been defined as a complex condition with physical, psychological, emotional, and social components. The prevalence of chronic pain in the adult population ranges from 2% to 40%, with a median point prevalence of 15%. Among chronic pain disorders, pain arising from various structures of the spine constitutes the majority of the problems. The lifetime prevalence of spinal pain has been reported as 54% to 80%. Studies of the prevalence of low back pain and neck pain and its impact in general have shown 23% of patients reporting Grade II to IV low back pain (high pain intensity with disability) versus 15% with neck pain. Further, age related prevalence of persistent pain appears to be much more common in the elderly associated with functional limitations and difficulty in performing daily life activities. Chronic persistent low back and neck pain is seen in 25% to 60% of patients, one-year or longer after the initial episode. Spinal pain is associated with significant economic, societal, and health impact. Estimates and patterns of productivity losses and direct health care expenditures among individuals with back and neck pain in the United States continue to escalate. Recent studies have shown significant increases in the prevalence of various pain problems including low back pain. Frequent use of opioids in managing chronic non-cancer pain has been a major issue for health care in the United States placing a significant strain on the economy with the majority of patients receiving opioids for chronic pain necessitating an increased production of opioids, and escalating costs of opioid use, even with normal intake. The additional costs of misuse, abuse, and addiction are enormous. Comorbidities including psychological and physical conditions and numerous other risk factors are common in spinal pain and add significant complexities to the interventionalist's clinical task. This section of the American Society of Interventional Pain Physicians (ASIPP)/Evidence-Based Medicine (EBM) guidelines evaluates the epidemiology, scope, and impact of spinal pain and its relevance to health care interventions.

TI Description of Documentation in the Management of Chronic Spinal Pain SO PAIN PHYSICIAN LA English DT Article DE Documentation; billing; coding; compliance; fraud and abuse; interventional techniques; evaluation and management services; office visit; consultation; new patient; established patient AB Documentation assists health care professionals in providing appropriate services to patients by documenting indications and medical necessity, and reflects the competency and character of the physician. Documentation is considered a cornerstone of the quality of patient care. This is nowhere more true than in interventional pain management. Thus, documentation in physicians' offices, hospital settings, ambulatory surgery centers, rehabilitation centers, and other settings must be accurate, complete, and reflect all of the services provided during each encounter. The Centers for Medicare and Medicaid Services (CMS) defines medical necessity in these terms: "no payment may be made under Part A or Part B for any expense incurred for items or services which are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a participant." The American Medical Association (AMA) defines medical necessity as, "health care services or procedures that a prudent physician would provide to a patient for the purpose of preventing, diagnosing, or treating an illness, injury, disease, or its symptoms in a manner that is in accordance with generally accepted standards of medical practice, clinically appropriate in terms of type, frequency, extent, site, and duration, and not primarily for the convenience of the patient, physician, or other health care provider." Documentation requirements include an appropriate medical record utilizing recognized and acceptable standards of documentation and an established process. However, the evolution of electronic medical records (EMRs) or electronic health records (EHRs) nullifies many of the issues faced in handwritten documentation. Multiple types of documentation include evaluation and management services and documentations in ambulatory surgery centers, hospital outpatient departments, and in office settings, specifically while performing interventional procedures. Evaluation and management services incorporate 5 levels of service for consultations and visits, with multiple key elements of service including history, physical examination, and medical decision making. Documentation of interventional procedures in general requires a history and physical, indication and medical necessity, intra-operative procedural description, post-operative monitoring and ambulation, discharge, and disposition. With minor variations, these requirements are similar for an in-office setting, hospital out patient department, and ambulatory surgery centers.

TI Comprehensive Review of Neurophysiologic Basis and Diagnostic Interventions in Managing Chronic Spinal Pain SO PAIN PHYSICIAN LA English DT Review DE Diagnostic interventional techniques; chronic spinal pain; facet joint interventions; epidural procedures; provocation discography; sacroiliac joint blocks; post lumbar surgery syndrome; spinal stenosis; provocation discography AB Background: Understanding the neurophysiological basis of chronic spinal pain and diagnostic interventional techniques is crucial in the proper diagnosis and management of chronic spinal pain.Central to the understanding of the structural basis of chronic spinal pain is the provision of physical diagnosis and validation of patient symptomatology. It has been shown that history, physical examination, imaging, and nerve conduction studies in non-radicular or discogenic pain are unable to diagnose the precise cause in 85% of the patients. In contrast, controlled diagnostic blocks have been shown to determine the cause of pain in as many as 85% of the patients. Objective: To provide evidence-based clinical practice guidelines for diagnostic interventional techniques. Design: Best evidence synthesis. Methods: Strength of evidence was assessed by the U.S. Preventive Services Task Force (USPSTF) criteria utilizing 5 levels of evidence ranging from Level I to III with 3 subcategories in Level II. Diagnostic Criteria: Diagnostic criteria established by systematic reviews were utilized with controlled diagnostic blocks. Diagnostic criteria included at least 80% pain relief with controlled local anesthetic blocks with the ability to perform multiple maneuvers which were painful prior to the diagnostic blocks for facet joint and sacroiliac joint blocks, whereas for provocation discography, the criteria included concordant pain upon stimulation of the target disc with 2 adjacent discs producing no pain at all. Results: The indicated level of evidence for diagnostic lumbar, cervical, and thoracic facet joint nerve blocks is Level I or II-1. The indicated evidence is Level II-2 for lumbar and cervical discography, whereas it is Level II-3 for thoracic provocation discography. The evidence for diagnostic sacroiliac joint nerve blocks is Level II-2. Level of evidence for selective nerve root blocks for diagnostic purposes is Level II-3. Limitations: Limitations of this guideline preparation include a continued paucity of literature and conflicts in preparation of systematic reviews and guidelines. Conclusion: These guidelines include the evaluation of evidence for diagnostic interventional procedures in managing chronic spinal pain and recommendations. However, these guidelines do not constitute inflexible treatment recommendations. These guidelines also do not represent a "standard of care."

Clinical practice guidelines present statements of best practice based on a thorough evaluation of the evidence from published studies on the outcomes of treatment. In November 1989, Congress mandated the creation of the Agency for Healthcare Policy and Research (AHCPR). AHCPR was given broad responsibility for supporting research, data development, and related activities. Associated with this mandate, the National Academy of Sciences published a document indicating that guidelines are expected to enhance the quality, appropriateness, and effectiveness of health care services. Guidelines as a whole have been characterized by multiple conflicts in terminology and technique. These conflicts are notable for the confusion they create and for what they reflect about differences in values, experiences, and interest among different parties. Despite this confusion, public and private development of guidelines is growing exponentially. There are only limited means to coordinate these guidelines in order to resolve inconsistencies, fill in gaps, track applications and results, and assess the soundness of individual guidelines. Significant diversity exists in clinical practice guidelines. The inconsistency amongst guidelines arises from variations in values, tolerance for risks, preferences, expertise, and conflicts of interest. In 2000, the American Society of Interventional Pain Physicians (ASIPP) first created treatment guidelines to help practitioners. There have been 4 subsequent updates. These guidelines address the issues of systematic: evaluation and ongoing care of chronic or persistent pain, and provide information about the scientific basis of recommended procedures. These guidelines are expected to increase patient compliance, dispel misconceptions among providers and patients, manage patient expectations reasonably, and form the basis of a therapeutic partnership between the patient, the provider, and payors. The ASIPP guidelines are based on evidence-based medicine (EBM). EBM is in turn based on 4 basic contingencies: the recognition of the patient's problem and the construction of a structured clinical question; the ability to efficiently and effectively search the medical literature to retrieve the best available evidence to answer the clinical question; clinical appraisal of the evidence; and integration of the evidence with all aspects of the individual patient's decision-making to determine the best clinical care of the patient. Evidence synthesis for guidelines includes the review of all relevant systematic reviews and individual articles, grading them for relevance, methodologic quality, consistency, and recommendations.

Our objective was to understand hospital staff perceptions of the role of acute care hospital medical doctors in end-of-life treatment intensity. In 11 purposively sampled Pennsylvania hospitals, we completed 108 audiotaped semistructured interviews with key informants involved in decision making or discharge planning. Using grounded theory, we qualitatively analysed transcripts using constant comparison to identify factors affecting end-of-life treatment decisions. A predominant theme identified was that end-of-life treatment intensity depends on the doctor. Communication with patients and families and collaboration with other care team members also were reported to vary, contributing to treatment variation. Informants attributed physician variation to individual beliefs and attitudes regarding the end-of-life (religion and culture, determination of when a patient is dying, quality-of-life determination and fear of failing) and to socialization by and interaction with the healthcare system (training, role perception, experience and response to incentives). When end-of-life treatment depends on the doctor, patient and family preferences may be neglected. Targeted interventions may reduce variability and align end-of-life treatment with patient wishes.

Adenosine A(2A) receptors have a selective localization to the basal ganglia and specifically to the indirect output pathway, and as a consequence offer a unique opportunity to modulate the output from the striatum that is believed critical to the occurrence of motor components of PD. Indeed, the ability of A(2A) antagonists to modulate basal ganglia neurotransmission has been shown to be associated with improved motor function in experimental models of PD. This suggests that A(2A) antagonists would be effective as a symptomatic treatment in humans without provoking marked dyskinesia. Indeed, the A(2A) antagonist istradefylline reduces OFF time in moderate- to late-stage patients with PD already receiving dopaminergic therapy, with an increase in non-troublesome dyskinesia. Adenosine and adenosine receptors also exert actions relevant to pathogenesis in PD, raising the possibility of their use as neuroprotective agents. Both epidemiologic evidence and the current preclinical data strongly support a role for A(2A) antagonists in protecting dopaminergic neurons and influencing the onset and progression of PD.

A third putatively pathogenic variant (R1441H) has been identified in four probands of diverse ethnicity with parkinsonism. Herein we show that the R1441H substitutions lie on different haplotypes within our patients, confirming this codon as a mutational hotspot. The absence of this variant in control subjects and the presence of two other pathogenic variants at this amino acid position collectively support the contention that 81441 H is a pathogenic substitution.

TI Negative emotions in cancer care: Do oncologists' responses depend on severity and type of emotion? SO PATIENT EDUCATION AND COUNSELING LA English DT Article DE Doctor-patient relations; Communication; Cancer; Emotion ID COMMUNICATION; DOCTOR; NEWS AB Objective: To examine how type and severity of patients' negative emotions influence oncologists' responses and subsequent conversations. Methods: We analyzed 264 audio-recorded conversations between advanced cancer patients and their oncologists. Conversations were coded for patients' expressions of negative emotion, which were categorized by type of emotion and severity. Oncologists' responses were coded as using either empathic language or blocking and distancing approaches. Results: Patients presented fear more often than anger or sadness; severity of disclosures was most often moderate. Oncologists responded to 35% of these negative emotional disclosures with empathic language. They were most empathic when patients presented intense emotions. Responding empathically to patients' emotional disclosures lengthened discussions by an average of only 21 s. Conclusion: Greater response rates to severe emotions suggest oncologists may recognize negative emotions better when patients express them more intensely. Oncologists were least responsive to patient fear and responded with greatest empathy to sadness. Practice implications: Oncologists may benefit from additional training to recognize negative emotions, even when displayed without intensity. Teaching cancer patients to better articulate their emotional concerns may also enhance patient-oncologist communication. (c) 2008 Elsevier Ireland Ltd. All rights reserved.

A surgeon is trained to perform this life-saving procedure whereas most anesthesiologists are not facile with the scalpel. It is for this reason that many percutaneous devices have been developed for use by surgeons and nonsurgeons alike. Unfortunately, the majority of such devices are designed for use in adults and/or teenagers but are not appropriate for neonates and infants. The unique anatomy of the infant larynx, the small size of the cricothyroid membrane, and the technical difficulty of locating the correct anatomical structures make the use of most of these devices impractical if not outright dangerous in neonates and infants. This paper will review many (but not all) of the available devices, associated literature, pitfalls and dangers. It is emphasized that each clinician should become familiar with the advantages and disadvantages of these devices and obtain training with simulators or animal models. A strategy for management of the 'cannot ventilate, cannot oxygenate, cannot intubate' situation should be developed with age and size appropriate equipment.

Inhalation injury remains a predictor of morbidity and mortality in burn injury. Inhalation of smoke and toxic gases leads to pulmonary complications, including airway obstruction from bronchial casts, pulmonary edema, decreased pulmonary compliance, and ventilation-perfusion mismatch, as well as systemic toxicity from carbon monoxide poisoning and cyanide toxicity. The diagnosis of inhalation injury is suggested by the history and physical exam and can be confirmed by bronchoscopy. Management consists of supportive measures, pulmonary toilet, treatment of pulmonary infection and ventilatory support as needed. This review details the pathophysiology, diagnosis, and management options for inhalation injury.

Sunitinib inhibits KIT and other members of the split-kirase-domain family of receptor tyrosine kinases. Sunitinib prolong; survival in adult patients with imatinib-resistant gastrointestinal stroinal tumor (GIST). We report the experience with sunitinib in pediatric patients with advanced GIST following failure of imatinib. Procedure. Sunitinib therapy was provided through a treatment-use protocol. Patients were 10-17 years old at enrollment. All patients had GIST resistant to imatinib therapy. Sunitinib was administered daily for 4 weeks in 6-week treatment cycles. KIT and platelet-derived growth factor receptor alpha (PDGFRA) genotyping of tumor tissue were performed. Results. One patient achieved a partial response, five patients had stable disease and one patient had progressive disease on sunitinib. The duration of disease stabilization was between 7 and 21 + months, with a mean of 15 months. Time to tumor progression was longer on sunitinib than on prior imatinib treatment for five of six patients. Two patients experienced grade 3 adverse events. All other adverse events were grade 1-2. None of the five patients tested had mutations in KIT or PDGFRA. Conclusion. Sunitinib treatment was associated with substantial initial antitumor activity and acceptable tolerability in this group of pediatric patients with imatinib-resistant GIST.

Strict adherence to immunizations against encapsulated organisms is recommended. We performed a cross-sectional study to determine immunization Status after splenectomy in the hereditary spherocytosis (HS) Population. As HS is most often autosomal dominant, we used a strategy of ascertaining older affected individuals by expanding pedigrees from patients in Our pediatric hematology center. Only 26% of asplenic patients reported receiving all recommended post-splenectomy vaccines. This study demonstrates that pediatric hematology clinics have a unique opportunity to provide or recommend catch-Up and booster vaccinations to splenectomized adult relatives of their patients.

However, the effect of chronic calcium changes and different vitamin D doses on these PTH measurements remains to be defined. In this study, 60 pediatric dialysis patients, aged 13.9 +/- 0.7 years, with secondary hyperparathyroidism were randomized to 8 months of therapy with oral vitamin D combined with either calcium carbonate (CaCO3) or sevelamer. Serum phosphorus levels did not differ between groups. Serum calcium levels rose from 9.3 +/- 0.1 to 9.7 +/- 0.1 mg/dl during CaCO3 therapy (p < 0.01 from baseline) but remained unchanged during sevelamer therapy. In the CaCO3 and sevelamer groups, baseline serum PTH levels (1st PTH-IMA; Nichols Institute Diagnostics, San Clemente, CA) were 964 +/- 75 and 932 +/- 89 pg/ml, and levels declined to 491 +/- 55 and 543 +/- 59 pg/ml, respectively (nonsignificant between groups). Patients treated with sevelamer received higher doses of vitamin D than those treated with CaCO3. The PTH values obtained by first- and second-generation PTH-IMAs correlated closely throughout therapy and the response of PTH was similar to both PTH-IMAs, despite differences in serum calcium levels.

We tested the association between stimulant treatment and the subsequent development of psychiatric comorbidity in a longitudinal sample of patients with ADHD. METHODS: We conducted a case-control, 10-year prospective follow-up study into young-adult years of youth with ADHD. At baseline, we assessed consecutively referred white male children with (n = 140) and without (n = 120) ADHD, aged 6 to 18 years. At the 10-year follow-up, 112 (80%) and 105 (88%) of the children in the ADHD and control groups, respectively, were reassessed (mean age: 22 years). We examined the association between stimulant treatment in childhood and adolescence and subsequent comorbid disorders and grade retention by using proportional hazards survival models. RESULTS: Of the 112 participants with ADHD, 82 (73%) were previously treated with stimulants. Participants with ADHD who were treated with stimulants were significantly less likely to subsequently develop depressive and anxiety disorders and disruptive behavior and less likely to repeat a grade compared with participants with ADHD who were not treated. CONCLUSIONS: We found evidence that stimulant treatment decreases the risk for subsequent comorbid psychiatric disorders and academic failure in youth with ADHD.

Adverse drug reactions owing to over- or under-dosing are common. It is now established that genetic differences between individuals play a major role in warfarin metabolism. In particular, common variants in CYP2C9 ((star)2 and (star)3) and VKORC1 (-1639G>A) have been associated with a reduced drug-dosage requirement. Materials & methods: We have evaluated the performance of five platforms that can be used to genotype individuals for these variants. These include Third Wave Technologies Invader (R), Applied Biosystems TaqMan (R), AutoGenomics INFINITI (TM) 2C9-VKORC1 assay, Osmetech eSensor (R) XT-8 warfarin sensitivity test and the Idaho Technologies LightScanner (R). Results & conclusions: Excluding failures, all of these technologies had 100% concordance rates with either Sanger sequencing or another validated technology. All of these platforms had high sensitivity and specificity and are therefore appropriate for clinical molecular diagnostics. Therefore, platform choice is likely to be driven by clinical laboratories interested in performing this service taking other factors into account, including turnaround time, capacity, cost and ease of use.

Brain states are real. The problem is that the two are not real in the same way, creating the mind-brain correspondence problem. In this article, I present a possible solution to this problem that involves two suggestions. First, complex psychological states such as emotion and cognition can be thought of as constructed events that can be causally reduced to a set of more basic, psychologically primitive ingredients that are more clearly respected by the brain. Second, complex psychological categories like emotion and cognition are the phenomena that require explanation in psychology, and, therefore, they cannot be abandoned by science. Describing the content and structure of these categories is a necessary and valuable scientific activity.

Whereas denervation quickly results in muscle fibrillations, SCI causes delayed onset of muscle spasticity. To compare the influence of denervation or SCI on muscle atrophy and atrophy-related gene expression, male rats had transection of either the spinal cord or sciatic nerve and were sacrificed 3, 7, or 14 days later. Rates of atrophy increased gradually over the first week after denervation and then were constant. In contrast, atrophy after SCI peaked at 1 week, then declined sharply. The greater atrophy after SCI compared to denervation was preceded by high levels of ubiquitin ligase genes, MAFbx and MuRF1, which then also markedly declined. After denervation, however, expression of these genes remained elevated at lower levels throughout the 2-week time course. Interestingly, expression of the muscle growth factor, IGF-1 was increased at 3 days after denervation when fibrillation also peaks compared to SCI. Expression of IGF-1R, GADD45, myogenin, and Runx1 were also initially increased after denervation or SCI, with later declines in expression levels which correlated less well with rates of atrophy. Thus, there were significant time-dependent differences in muscle atrophy and MAFbx, MuRF1, and IGF-1 expression following SCI or denervation which may result from distinct temporal patterns of spontaneous muscle contractile activity due to injury to upper versus lower motor neurons.

Genetic lesions inactivating this pathway contribute to pancreatic tumor progression in mouse models. Transcriptional Intermediary Factor 1 gamma (TIF1 gamma) has recently been proposed to be involved in TGF beta signaling, functioning as either a positive or negative regulator of the pathway. Here, we addressed the role of TIF1 gamma in pancreatic carcinogenesis. Using conditional Tif1 gamma knockout mice (Tif1 gamma(lox/lox)), we selectively abrogated Tif1 gamma expression in the pancreas of Pdx1-Cre;Tif1 gamma(lox/lox) mice. We also generated Pdx1-Cre;LSL-Kras(G12D);Tif1 gamma(lox/lox) mice to address the effect of Tif1 gamma loss-of-function in precancerous lesions induced by oncogenic Kras(G12D). Finally, we analyzed TIF1 gamma expression in human pancreatic tumors. In our mouse model, we showed that Tif1 gamma was dispensable for normal pancreatic development but cooperated with Kras activation to induce pancreatic tumors reminiscent of human Intraductal Papillary Mucinous Neoplasms (IPMNs). Interestingly, these cystic lesions resemble those observed in Pdx1-Cre;LSL-Kras(G12D);Smad4(lox/lox) mice described by others. However, distinctive characteristics, such as the systematic presence of endocrine pseudo-islets within the papillary projections, suggest that SMAD4 and TIF1 gamma don't have strictly redundant functions. Finally, we report that TIF1 gamma expression is markedly down-regulated in human pancreatic tumors by quantitative RT-PCR and immunohistochemistry supporting the relevance of these findings to human malignancy. This study suggests that TIF1 gamma is critical for tumor suppression in the pancreas, brings new insight into the genetics of pancreatic cancer, and constitutes a promising model to decipher the respective roles of SMAD4 and TIF1 gamma in the multifaceted functions of TGF beta in carcinogenesis and development.

TI HIV-1 Replication Is Differentially Regulated by Distinct Clinical Strains of Mycobacterium tuberculosis SO PLOS ONE LA English DT Article AB Background: Tuberculosis ( TB) is the largest cause of death in human immunodeficiency virus type 1 (HIV-1) infection, having claimed an estimated one third to one half of the 30 million AIDS deaths that have occurred worldwide. Different strains of Mycobacterium tuberculosis (MTb), the causative agent of TB, are known to modify the host immune response in a strain-specific manner. However, a MTb strain-specific impact upon the regulation of HIV-1 replication has not previously been established. Methology/Principal Findings: We isolated normal human peripheral blood mononuclear cells (PBMC) and co-infected them with HIV-1 and with either the well characterized CDC1551 or HN878 MTb clinical isolate. We show that HIV-1 co-infection with the CDC1551 MTb strain results in higher levels of virus replication relative to co-infection with the HN878 MTb strain ex vivo. Furthermore, we show that the distinct pattern of CDC1551 or HN878 induced HIV-1 replication is associated with significantly increased levels of TNF and IL-6, and of the transcription and nuclear translocation of the p65 subunit of the transcription factor NF-kappa B, by CDC1551 relative to HN878. Conclusions/Significance: These results provide a precedent for TB strain-specific effects upon HIV-1 replication and thus for TB strain-specific pathogenesis in the outcome of HIV-1/TB co-infection. MTb strain-specific factors and mechanisms involved in the regulation of HIV-1 during co-infection will be of importance in understanding the basic pathogenesis of HIV-1/TB co-infection.

Herein we present two crystal structures containing the N-terminal and the catalytic core domains of maedi-visna virus IN in complex with the IN binding domain of the common lentiviral integration co-factor LEDGF. The structures reveal that the dimer-of-dimers architecture of the IN tetramer is stabilized by swapping N-terminal domains between the inner pair of monomers poised to execute catalytic function. Comparison of four independent IN tetramers in our crystal structures elucidate the basis for the closure of the highly flexible dimer-dimer interface, allowing us to model how a pair of active sites become situated for concerted integration. Using a range of complementary approaches, we demonstrate that the dimer-dimer interface is essential for HIV-1 IN tetramerization, concerted integration in vitro, and virus infectivity. Our structures moreover highlight adaptable changes at the interfaces of individual IN dimers that allow divergent lentiviruses to utilize a highly-conserved, common integration co-factor.

Methods Literature and new cases classified as Group I (pre-HRAS), Group II (HRAS confirmed). and Group III (HRAS confirmed ill natural history study. Plus three contributed cases). Results Polyhydramnios Occurred in most (mean 79%) pregnancies of cases in Groups 1 (98) 11 (107), and III (17); advanced paternal age and prematurity were noted in approximately half. Less frequent were nuchal thickening. ascites, shortened long, bones. abnormal hand posture. ventriculomegaly, macrosomia, and macrocephaly. Fetal arrhythmia Occurred in nine cases (six supraventricular or unspecified tachycardia, one Unspecified arrhythmia. and two premature atrial contractions. PACs); excluding three new cases and two with PACs, the estimated prenatal frequency is 4/222 (2%). Conclusion Costello syndrome can be suspected prenatally when polyhydramnios is accompanied by nuchal thickening, hydrops, shortened long bones, abnormal hand Posture. ventriculomegaly, large size, and macrocephaly, and especially fetal atrial tachycardia. Consideration should be given for timely prenatal diagnostic Studies for continuative HRAS gene mutations and for maternal treatment of serious fetal arrhythmia.

In this study, we investigated the effect of malnutrition on macrophage production of cytokines, prostaglandins (PCs), and leukotrienes (LTs). Using either LPS or calcium ionophore A23187 as a stimulus, macrophages from the malnourished mice produced a 3-fold higher PG/LT ((PGE(2)+6-keto-PGF(1 alpha))/(LTB(4)+cysteinyl leukotrienes)) ratio than macrophages from well-nourished mice. LPS-stimulated macrophages from the malnourished mice produced decreased levels of TNF-alpha, GM-CSF, and IL-10, but similar levels of IL-6 and NO compared to well-nourished mice. A complex crosstalk between the eicosanoids and cytokines in the LPS-stimulated macrophages from the malnourished mice was evident by the following: ( I) high levels of PC secretion despite low levels of TNF-alpha; (2) Supplemental IL-10 modulated the excessive PC production; (3) GM-CSF rectified the PG/LT ratio, but did not correct the abnormal cytokine profile: and (4) inhibitors of cyclooxygenase decreased the PG/LT ratio, but did not affect TNF-alpha. Thus, in this model of malnutrition, there is a relative increase in anti-inflammatory PCs compared to pro-inflammatory LTs, which may contribute to immunodeficiency. Published by Elsevier Ltd.

We screened linoleic acid, other fatty acids, and some of their derivatives and found that an epoxy-keto derivative of linoleic acid (but neither linoleic acid itself nor others of its oxidation products) strongly activates the antioxidant response element (ARE) in IMR-32 neuroblastoma cells and cerebro-cortical neurons. The active compound, 12,13-epoxy-9-keto-10(trans)-octadecenoic acid (EKODE), induces the expression of ARE-regulated cytoprotective genes such as NQO1 at the transcript and protein levels. EKODE requires transcription factor NRF2 and PI3-kinase for ARE activity. The results suggest that specific oxidation products of linoleic acid may initiate responses that lessen damage caused by oxidative stress. (C) 2009 Elsevier Ltd. All rights reserved.

We have demonstrated that TX527 affects dendritic cell (DC) maturation in vitro, resulting in the generation of a tolerogenic cell. In the present study, we aimed to explore the global protein changes induced by the analogue in immature DC (iDC) and mature human DC and to correlate them with alterations in DC morphology and function. Human CD14(+) monocytes were differentiated toward iDC or mature DCs, in the presence or absence of TX527 (10(-8) M) (n = 4). Protein samples were separated into two different pH ranges (pH4-7 and 6-9), analyzed by 2-D DIGE and differentially expressed spots (p<0.01) were identified by MALDI-TOF/TOF (76.3 and 70.7% in iDC and mature DCs, respectively). Differential protein expression revealed three protein groups predominantly affected by TX527 treatment, namely proteins involved in cytoskeleton structure, in protein biosynthesis/proteolysis and in metabolism. Moreover, protein interactome-network analysis demonstrated dose interaction between these different groups (p<0.001) and morphological and functional analyses confirmed the integrated effect of TX527 on human DCs, resulting in a cell with altered morphology, cell surface marker expression, endocytic and migratory capacity.

TI VA Intensive Mental Health Case Management in Urban and Rural Areas: Veteran Characteristics and Service Delivery SO PSYCHIATRIC SERVICES LA English DT Article ID ASSERTIVE COMMUNITY TREATMENT; SUBSTANCE-ABUSE; SEVERITY; PROGRAM; FIDELITY; SCALE; MODEL AB Objective: The availability of mental health services in rural areas-particularly intensive services such as assertive community treatment (ACT)-has been of increasing concern and was the focus of this study. In recent decades the U. S. Department of Veterans Affairs (VA) has developed a national network of ACT-like programs called mental health intensive case management (MHICM), which have served veterans from diverse locations across the country, including urban and rural areas. Methods: This study used rural-urban commuting area codes and national VA administrative data to compare characteristics of veterans and patterns of MHICM service delivery among veterans with mental illness living in large urban, large rural, small rural, and isolated rural communities. Results: Among veterans enrolled in MHICM from FY 2000 to FY 2005 (N=5,221), 84% (N=4,373) resided in urban areas, 8% (N=421) in large cities, 6% (N=291) in small rural towns, and 3% (N=136) in isolated rural areas. MHICM participants who lived in rural areas had clinical problems broadly similar to those in urban areas, although more rural veterans were unemployed, disabled, received VA disability compensation, and had a payee or fiduciary. MHICM clients in smaller or isolated rural areas received slightly less frequent and less intensive contacts and less recovery-oriented services than those in large urban locations. Conclusions: These data highlight the need for intensive case management services in rural areas and note some challenges in providing them at the intensity and frequency observed in urban areas where travel distances and times are shorter.

The role played by anxiety in the history of psychiatric epidemiology has not been well recognized. Such lack of understanding retarded the incremental growth of psychiatric research in general populations. It seems useful to look back oil this history while deliberations are being carried out about how anxiety will be presented in DSM-V. Method. Drawing on the literature and our own research, we examined work that was carried out during and after the Second World War by a Research Branch of the United States War Department, by the Stirling County Study, and by the Midtown Manhattan Study. The differential influences of Meyerian psychobiology and Freudian psychoanalysis are noted. Results. The instruments developed in the early epidemiologic endeavors used questions about nervousness, palpitations, sweating, trembling, shortness of breath, upset stomach, etc. These symptoms are important features of what the clinical literature called 'manifest', 'free-floating' or 'chronic anxiety'. A useful descriptive name is I autonomic anxiety'. Conclusions. Although not focusing oil specific circumstances as in Panic and Phobic disorders, a non-specific form of autonomic anxiety is a common, disabling and usually chronic disorder that received empirical verification in studies of several community populations. It is suggested that two types of general anxiety may need to be recognized, one dominated by excessive worry and feelings of stress, as in the current DSM-IV definition of Generalized Anxiety Disorder (GAD), and another emphasizing frequent unexplainable autonomic fearfulness, as in the early epidemiologic studies.

Objective: The authors assessed the associations between abuse, symptoms, and mental health utilization. Method: The authors performed a cross-sectional survey of 380 adult female, internal-medicine patients. Results: Although both IPV and childhood abuse were associated with depressive and physical symptoms, IPV was independently associated with physical symptoms, and childhood abuse was independently associated with depression. Women with a history of childhood abuse had higher odds, whereas women with IPV had lower odds, of receiving care from mental health providers. Conclusion: IPV and childhood abuse may have different effects on women's symptoms and mental health utilization.

However, the biologic effects that may connect these two seemingly unrelated disorders is not well understood. Objective: This study aimed for a comprehensive evaluation of anxiety in stable CHD patients, in addition to cardiac biomarkers such as C-reactive protein (CRP), troponin T, and amino-terminal pro-B-type brain natriuretic peptide. Method: The study included 43 CHD patients with anxiety disorder and 42 CHD patients without psychiatric disorder given the Structured Clinical Interview for DSM-IV. Results: Regression analyses showed an association between anxiety (anxiety disorder, not otherwise specified) and CRP levels, despite model adjustment for various related demographic and clinical variables. Anxiety was associated with CRP levels. Conclusion: There are significant associations between anxiety and CHD risk, with a potential biologic link between anxiety and elevations in a biomarker with powerful prognostic risk, namely CRP. It is not clear whether this association is directly causal or relates to other medical processes among patients with heightened anxiety. The findings suggest that the current focus on depressive disorders with respect to biomarkers and CHD outcomes should be broadened to include anxiety disorders, as well.

Objective: The authors sought to compare overall medical costs in nondepressed and depressed individuals. Method: Insurance claims for 618,780 patients were examined for total annual non-mental health cost of care in 11 chronic diseases. In each disease cohort, median annual non-mental health cost was calculated for individuals with and without depression. Results: Patients with depression had higher median per-patient annual non-mental health costs than patients without depression in all 11 diseases studied. There was a higher-than-random comorbidity between depression and all 11 chronic comorbid diseases. Conclusion: Even when controlling for number of chronic comorbid diseases, depressed patients had significantly higher costs than non-depressed patients, in a magnitude consistent across 11 chronic comorbid diseases.

Using cells of a WTK1 human lymphoblastoid cell line in suspension and a transwell insert system that precludes contact between targeted and bystander cells, we have shown that the bystander signaling is mediated by diffusing species. The extranuclear localization of the photosensitizer used suggests that primary DNA damage is not the trigger for initiating these bystander responses, which include elevated oxidative stress, DNA damage (micronucleus formation), mutagenesis and decreased clonogenic survival. In addition, oxidative stress in the bystander population was reduced by the presence of the membrane antioxidant vitamin E in the targeted cells, suggesting that lipid peroxidation may play a key role in mediating these bystander effects. The fluence responses for these bystander effects are non-linear, with larger effects seen at lower fluences and toxicity to the target cell population. Hence, when considering outcomes of photodynamic action in cells and tissue, bystander effects may be significant, especially at sublethal fluences.

TI Comatose Patients with Cardiac Arrest: Predicting Clinical Outcome with Diffusion-weighted MR Imaging SO RADIOLOGY LA English DT Article ID CEREBRAL-ISCHEMIA; CARDIOPULMONARY-RESUSCITATION; HUMAN BRAIN; INJURY; COEFFICIENT; SURVIVORS; PERFUSION; ENCEPHALOPATHY; HYPOTHERMIA; HYPOXIA AB Purpose: To examine whether the severity and spatial distribution of reductions in apparent diffusion coefficient ( ADC) are associated with clinical outcomes in patients who become comatose after cardiac arrest. Materials and Methods: This was an institutional review board-approved, HIPAA-compliant retrospective study of 80 comatose patients with cardiac arrest who underwent diffusion-weighted magnetic resonance imaging. The need to obtain informed consent was waived except when follow-up phone calls were required; in those cases, informed consent was obtained from the families. Mean patient age was 57 years +/- 16 (standard deviation); 31 (39%) patients were women. ADC maps were semiautomatically segmented into the following regions: subcortical white matter; cerebellum; insula; frontal, occipital, parietal, and temporal lobes; caudate nucleus; putamen; and thalamus. Median ADCs were measured in these regions and in the whole brain and were compared ( with a two-tailed Wilcoxon test) as a function of clinical outcome. Outcome was defined by both early eye opening in the 1st week after arrest ( either spontaneously or in response to external stimuli) and 6-month modified Rankin scale score. Results: Whole-brain median ADC was a significant predictor of poor outcome as measured by no eye opening (specificity, 100% [95% confidence interval {CI}: 86%, 100%]; sensitivity, 30% [ 95% CI: 18%, 45%]) or 6-month modified Rankin scale score greater than 3 ( specificity, 100% [ 95% CI: 73%, 100%]; sensitivity, 41% [95% CI: 29%, 54%]), with patients with poor outcomes having significantly lower ADCs for both outcome measures (P <= .001). Differences in ADC between patients with good and those with poor outcomes varied according to brain region, involving predominantly the occipital and parietal lobes and the putamen, and were dependent on the timing of imaging. Conclusion: Spatial and temporal differences in ADCs may provide insight into mechanisms of hypoxic-ischemic brain injury and, hence, recovery. C1 [Wu, Ona; Sorensen, A.

TI Dose Reduction and Compliance with Pediatric CT Protocols Adapted to Patient Size, Clinical Indication, and Number of Prior Studies SO RADIOLOGY LA English DT Article ID TUBE CURRENT MODULATION; IMAGE QUALITY; FOLLOW-UP; ROW CT; RADIATION; CHILDREN; ABDOMEN; PELVIS; OPTIMIZATION; UK AB Purpose: To assess compliance and resultant radiation dose reduction with new pediatric chest and abdominal computed tomographic (CT) protocols based on patient weight, clinical indication, number of prior CT studies, and automatic exposure control. Materials and Methods: The study was institutional review board approved and HIPAA compliant. Informed consent was waived. The new pediatric CT protocols, which were organized into six color zones based on clinical indications and number of prior CT examinations in a given patient, were retrospectively assessed. Scanning parameters were adjusted on the basis of patient weight. For gradual dose reduction, pediatric CT (n = 692) examinations were performed in three phases of incremental stepwise dose reduction during a 17-month period. There were 245 male patients and 193 female patients (mean age, 12.6 years). Two radiologists independently reviewed CT images for image quality. Data were analyzed by using multivariate analysis of variance. Results: Compliance with the new protocols in the early stage of implementation ( chest CT, 58.9%; abdominal CT, 65.2%) was lower than in the later stage ( chest CT, 88%; abdominal CT, 82%) ( P < .001). For chest CT, there was 52.6% (9.1 vs 19.2 mGy) to 85.4% (2.8 vs 19.2 mGy) dose reduction in the early stage of implementation and 73.5% (4.9 vs 18.5 mGy) to 83.2% (3.1 vs 18.5 mGy) dose reduction in the later stages compared with dose at noncompliant examinations (P < .001); there was no loss of clinically relevant image quality. For abdominal CT, there was 34.3% (9.0 vs 13.7 mGy) to 80.2% (2.7 vs 13.7 mGy) dose reduction in the early stage of implementation and 62.4% (6.5 vs 17.3) to 83.8% ( 2.8 vs 17.3 mGy) dose reduction in the later stage ( P < .001). Conclusion: Substantial dose reduction and high compliance can be obtained with pediatric CT protocols tailored to clinical indications, patient weight, and number of prior studies.

TI A Stress-Busting Program for Family Caregivers SO REHABILITATION NURSING LA English DT Article DE Alzheimer's disease; Alzheimer's disease and related dementias; caregiving.; intervention; stress ID RELAXATION THERAPY; SYMPTOM QUESTIONNAIRE; HEALTH; DEPRESSION; SPOUSAL; IMPACT AB Aging baby boomers, longer life spans, and rising levels of Alzheimer's disease and related dementias (ADRD) will result in a caregiver crisis in the near future. The ways in which caregivers deal with stresses related to caregiving will be critical to both their own well-being and their ability to care for others. The purpose of this article is to describe the Stress-Busting Program (SBP) for family caregivers and its effectiveness. The essential components of the SBP are education, stress management, problem solving, and support delivered in a group setting for 9 weeks. Results of the SBP indicate that throughout the program, caregivers experienced significant improvements in general health, vitality, social function, and mental health scores and decreases in anxiety anger/hostility, depression, perceived stress, and caregiver burden. The SBP is a cost-effective health-promotion strategy for caregivers who have substantial ongoing stress.

We describe the approaches to and components of adult asthma disease-management interventions, examine the outcomes evaluated, and assess the quality of published studies. METHODS: We searched the MEDLINE, EMBASE, CINAHL, PsychInfo, and Cochrane databases for studies published in 1986 through 2008, on adult asthma management. With the studies that met our inclusion criteria, we examined the clinical, process, medication, economic, and patient-reported outcomes reported, and the study designs, provider collaboration during the studies, and statistical methods. RESULTS: Twenty-nine articles describing 27 studies satisfied our inclusion criteria. There was great variation in the content, extent of collaboration between physician and non-physician providers responsible for intervention delivery, and outcomes examined across the 27 studies. Because of limitations in the design of 22 of the 27 studies, the differences in outcomes assessed, and the lack of rigorous statistical adjustment, we could not draw definitive conclusions about the effectiveness or cost-effectiveness of the asthma disease-management programs or which approach was most effective. CONCLUSIONS: Few well-designed studies with rigorous evaluations have been conducted to evaluate disease-management interventions for adults with asthma. Current evidence is insufficient to recommend any particular intervention. C1 [Maciejewski, Matthew L.] Durham Vet Affairs Med Ctr, Ctr Hlth Serv Res Primary Care, Durham, NC 27701 USA.

From a population of hyperuricaemic veterans of [serum urate level 416 mol/l (7.0 mg/dl)] at least 40 years of age, we compared the risk of death between incident allopurinol users (n 2483) and non-users (n 7441). We estimated the multivariate mortality hazard ratio (HR) of allopurinol use with Cox proportional hazards models. Results. Of the 9924 veterans (males, 98 and mean age 62.7 years), 1021 died during the follow-up. Patients who began treatment with allopurinol had worse prognostic factors for mortality, including higher BMI and comorbidities. After adjusting for baseline urate levels, allopurinol treatment was associated with a lower risk of all-cause mortality (HR 0.78; 95 CI 0.67, 0.91). Further adjustment with other prognostic factors did not appreciably alter this estimate (HR 0.77; 95 CI 0.65, 0.91). The mean change from baseline in serum urate within the allopurinol group was 111 mol/l (1.86 mg/dl). Adjusting for baseline urate level, allopurinol users had a 40 mol/l (0.68 mg/dl) lower follow-up serum urate value than controls (95 CI 0.55, 0.81). Conclusion. Our findings indicate that allopurinol treatment may provide a survival benefit among patients with hyperuricaemia.

SPD and Borderline personality disorder (BPD) are severe personality disorders characterized by social and cognitive dysfunction. However, while SPD is characterized by social withdrawal/anhedonia, BPD is marked by hyper-reactivity to interpersonal stimuli and hyper-emotionality. This is the first morphometric study to directly compare SPD and BPD patients in temporal lobe volume. Methods: We compared three age-, sex-, and education-matched groups: 27 unmedicated SPD individuals with no BPD traits, 52 unmedicated BPD individuals with no SPD traits, and 45 healthy controls. We examined gray matter volume of frontal and temporal lobe Brodmann areas (BAs), and dorsal/ventral amygdala from 3-T magnetic resonance imaging. Results: In the STG, an auditory association area reported to be dysfunctional in SPD and BPD, the SPD patients had significantly smaller volume than healthy controls and BPD patients. No group differences were found between BPD patients and controls. Smaller BA22 volume was associated with greater symptom severity in SPD patients. Reduced STG volume may be an important endophenotype for schizophrenia-spectrum disorders. SPD is distinct from BPD in terms of STG volume abnormalities which may reflect different underlying pathophysiological mechanisms and could help discriminate between them. (C) 2009 Elsevier B.V.

The average survival time of less than 1 year has not improved notably over the last 3 decades. Surgery and radiotherapy, the traditional cornerstones of therapy, provide palliative benefit, whereas the value of chemotherapy has been marginal and controversial. The dismal prognosis of glioblastoma patients is largely caused by the striking radioresistance of these tumors. A better understanding of the molecular mechanisms that underlie the malignant phenotype of glioblastomas and plausible mechanisms of radiation resistance can provide new possibilities in terms of targeted therapeutic strategies. Despite the genetic heterogeneity of malignant gliomas, common aberrations in the signaling elements of the growth and survival pathways are found. New treatments have emerged to target molecules in these signaling pathways with the goal to increase specific efficacy and minimize toxicity. Monoclonal antibodies and low molecular-weight kinase inhibitors are the most common classes of agents in targeted cancer treatment. This review introduces these new targeted therapies in the context of current treatment options for patients with glioblastoma. It is hoped that this combined approach will overcome the current limitations in the treatment of patients with glioblastoma and result in a better prognosis for these patients.

Because of these changes, the delivery of radiotherapy evolved from therapy designed primarily on plain 2-dimensional X-ray images and hand calculations to therapy based on 3-dimensional images incorporating increasingly complex computer algorithms in the planning process. In addition, challenges in treatment planning and radiation delivery, such as problems with setup error and organ movement, have begun to be systematically addressed, ushering in an era of so-called 4-dimensional radiotherapy. This review article discusses how these advances have changed the way in which many common neoplasms of the central nervous system are being treated at present.

The authors test this hypothesis by examining the moderating role of men's conformity to gender norms for sexual prowess on the relationship between sexual desire and depression. One hundred and sixteen male citizens of the United States with spinal cord injuries were recruited for participation in the internet-based survey. Results indicated that participants with strong sexual desire evinced higher rates of depression when they conformed to masculine norms emphasizing sexual prowess. Men with little reported sexual desire, by contrast, demonstrated lower rates of depression when they endorsed norms for prowess. Directions for future research and treatment interventions are offered.

TI Prevalent Hypertension and Stroke in the Sleep Heart Health Study: Association with an ECG-derived Spectrographic Marker of Cardiopulmonary Coupling SO SLEEP LA English DT Article DE ECG; cardiopulmonary coupling; Sleep Heart Health Study; sleep spectrogram; hypertension stroke ID CHEMICAL CONTROL STABILITY; UPPER AIRWAY MECHANICS; APNEA; INSTABILITY; RESPIRATION; BYPASS AB Study Objectives: The electrocardiogram (ECG)-based sleep spectrogram generates a map of cardiopulmonary coupling based on heart rate variability and respiration derived from QRS amplitude variations. A distinct spectrographic phenotype, designated as narrow-band elevated low frequency coupling (e-LFC(NB)), has been associated with central apneas and periodic breathing and predicts sleep laboratory failure of continuous positive airway pressure therapy. This study assesses, at a population level, the associations of this spectrographic biomarker with prevalent cardiovascular disease using the Sleep Heart Health Study (SHHS)-I dataset. Design: Retrospective analysis of the Sleep Heart Health Study-I dataset. Setting: Laboratory for complex physiologic signals analysis. Measurements and Results: The fully-automated ECG-derived sleep spectrogram technique was applied to 5247 (of the original 6441) polysomnograms from the SHHS-I. Associations were estimated with use of various drugs and pathologies including prevalent hypertension and cardiovascular and cerebrovascular disease. Increasing with age and more common in males, e-LFC(NB) is also associated with greater severity of sleep apnea and fragmented sleep. After adjustment for potential confounders, an independent association with prevalent hypertension and stroke was found. Conclusions: An ECG-derived spectrographic marker related to low frequency cardiopulmonary coupling is associated with greater sleep apnea severity. Whether this biomarker is solely a sign of more severe disease or whether it reflects primary alterations in sleep apnea pathophysiology (which may either cause or result from sleep apnea) is unknown. This ECG-based spectral marker is associated with a higher prevalence of hypertension and stroke.

Objectives: To determine whether Escherichia coli 83972-coated urinary catheters in persons with spinal cord injury (SCI) practicing an intermittent catheterization program (ICP) could (1) achieve bladder colonization with this benign organism and (2) decrease the rate of symptomatic urinary tract infection (UTI). Setting: Outpatient SCI clinic in a Veterans Affairs hospital (USA). Methods: Participants had neurogenic bladders secondary to SCI, were practicing ICP, had experienced at least one UTI and had documented bacteruria within the past year. All participants received a urinary catheter that had been pre-inoculated with E. coli 83972. The catheter was left in place for 3 days and then removed. Participants were followed with urine cultures and telephone calls weekly for 28 days and then monthly until E. coli 83972 was lost from the urine. Outcome measures were (1) the rate of successful bladder colonization, defined as the detection (>= 10(2) cfu ml(-1)) of E. coli 83972 in urine cultures for >3 days after catheter removal and (2) the rate of symptomatic UTI during colonization with E. coli 83972. Results: Thirteen participants underwent 19 insertions of study catheters. Eight participants (62%) became successfully colonized for 43 days after catheter removal. In these 8 participants, the rate of UTI during colonization was 0.77 per patient-year, in comparison with the rate of 2.27 UTI per patient-year before enrollment. Conclusions: E. coli 83972-coated urinary catheters are a viable means of achieving bladder colonization with this potentially protective strain in persons practicing ICP.

Existing work mainly concentrates on parameter estimation using Gibbs sampling, and no work has been conducted to understand and quantify the theoretical impact of ignoring measurement error on spatial data analysis in the form of the asymptotic biases in regression coefficients and variance components when measurement error is ignored. Plausible implementations, from frequentist perspectives, of maximum likelihood estimation in spatial covariate measurement error models are also elusive. In this paper, we propose a new class of linear mixed models for spatial data in the presence of covariate measurement errors. We show that the naive estimators of the regression coefficients are attenuated while the naive estimators of the variance components are inflated, if measurement error is ignored. We further develop a structural modeling approach to obtaining the maximum likelihood estimator by accounting for the measurement error. We study the large sample properties of the proposed maximum likelihood estimator, and propose an EM algorithm to draw inference. All the asymptotic properties are shown tinder the increasing-domain asymptotic framework. We illustrate the method by analyzing the Scottish lip cancer data, and evaluate its performance through a simulation study, all of which elucidate the importance of adjusting for covariate measurement errors.

The collection process is a logistical and ethical challenge and usually involves the use of excess oocytes donated after assisted reproduction procedures. We collected resected human ovarian tissue after routine surgical procedures. Oocytes were isolated from the tissue and matured in vitro to the meiosis II (MII) stage, when the first polar body is extruded. With the large antral and smaller preantral follicles, the efficiencies of the maturation were nearly 50% and 25%, respectively. The quality of the matured oocytes was assessed by inducing parthenogenesis and > 50% of the in vitro matured oocytes were competent enough to develop pronuclei and 33% developed at least to the two-cell stage 48 h after activation. Parthenotes continued to develop by 72 h but with significant blastomere fragmentation. These results provide evidence that resected ovarian tissue, which is normally discarded, may be a suitable alternative source for oocytes in hES cell research.

TI Cerebral Ischemic Events Associated With 'Bubble Study' for Identification of Right to Left Shunts SO STROKE LA English DT Article DE atrial heart septal defects; arteriovenous fistula; echocardiography; patent foramen ovale; stroke; transcranial Doppler ultrasonography; transesophageal echocardiography; transient ischemic attack ID CONTRAST ECHOCARDIOGRAPHY; AIR-EMBOLISM; STROKE; COMMITTEE AB Background and Purpose-Detection of an intracardiac shunt is frequently sought during the evaluation of patients with cryptogenic ischemic stroke and agitated saline intravenous injection, or "bubble study" (BS), is performed in most cases. We present the first attempt to identify the clinical features in patients who had cerebral ischemic events with BS. Methods-Using a list serve established by the American Academy of Neurology, a member posted a question regarding the safety of BS in patients with patent foramen ovale. A standardized questionnaire was used to gather data about patients with cerebral ischemic events, details of each case were reviewed, and the findings pooled. Results-Five patients with ischemic complications of BS (all female, aged 42 to 90 years) were identified from 4 institutions, 3 ischemic strokes and 2 transient ischemic attacks. Events occurred either during or within 5 minutes of BS. Early brain MRIs confirmed acute infarction in 3, including one who had transient symptoms. MRI infarct volumes were small, and deficits were mild in those who developed stroke. Diagnostic evaluation revealed a patent foramen ovale alone in one case, a pulmonary arteriovenous malformation in one case, and a patent foramen ovale and/or pulmonary shunt in 3 cases. Conclusions-Ischemic cerebrovascular complications can occur in patients who undergo BS and are associated with the presence of cardiac or pulmonary shunts. The true incidence and degree of disability remains unknown, and further study is indicated to assess the impact of technical differences in BS methodology. Novel methods to promote physician communication such as the use of electronic list serves may reduce barriers to reporting of drug, technique, or device complications and should be explored to identify rare complications that otherwise will likely go unappreciated.

TI Microbleeds Versus Macrobleeds Evidence for Distinct Entities SO STROKE LA English DT Article DE cerebral amyloid angiopathy; intracerebral hemorrhage; microbleeds ID CEREBRAL AMYLOID ANGIOPATHY; INTRACEREBRAL HEMORRHAGE; ISCHEMIC-STROKE; RISK-FACTORS; ECHO MRI; PREVALENCE; CADASIL; ASSOCIATIONS; VALIDATION; DEMENTIA AB Background and Purpose-Small, asymptomatic microbleeds commonly accompany larger symptomatic macrobleeds. It is unclear whether microbleeds and macrobleeds represent arbitrary categories within a single continuum versus truly distinct events with separate pathophysiologies. Methods-We performed 2 complementary retrospective analyses. In a radiographic analysis, we measured and plotted the volumes of all hemorrhagic lesions detected by gradient-echo MRI among 46 consecutive patients with symptomatic primary lobar intracerebral hemorrhage diagnosed as probable or possible cerebral amyloid angiopathy. In a second neuropathologic analysis, we performed blinded qualitative and quantitative examinations of amyloid-positive vessel segments in 6 autopsied subjects whose MRI scans demonstrated particularly high microbleed counts (>50 microbleeds on MRI, n=3) or low microbleed counts (<3 microbleeds, n=3). Results-Plotted on a logarithmic scale, the volumes of 163 hemorrhagic lesions identified on scans from the 46 subjects fell in a distinctly bimodal distribution with mean volumes for the 2 modes of 0.009 cm(3) and 27.5 cm3. The optimal cut point for separating the 2 peaks (determined by receiver operating characteristics) corresponded to a lesion diameter of 0.57 cm. On neuropathologic analysis, the high microbleed-count autopsied subjects showed significantly thicker amyloid-positive vessel walls than the low microbleed-count subjects (proportional wall thickness 0.53 +/- 0.01 versus 0.37 +/- 0.01; P<0.0001; n=333 vessel segments analyzed). Conclusions-These findings suggest that cerebral amyloid angiopathy-associated microbleeds and macrobleeds comprise distinct entities. Increased vessel wall thickness may predispose to formation of microbleeds relative to macrobleeds. (Stroke. 2009; 40: 2382-2386.) C1 [Greenberg, Steven M.; Nandigam, R. N.

TI CT Angiography for Intracerebral Hemorrhage Does Not Increase Risk of Acute Nephropathy SO STROKE LA English DT Article DE cerebral hemorrhage; tomography; X-ray computed; contrast media ID CONTRAST-INDUCED NEPHROPATHY; PREDICTS HEMATOMA EXPANSION; ACUTE STROKE; TOMOGRAPHY ANGIOGRAPHY; COMPUTED-TOMOGRAPHY; SAFETY; TRIAL; EXTRAVASATION; PERFUSION; WARFARIN AB Background and Purpose-CT angiography (CTA) is receiving increased attention in intracerebral hemorrhage (ICH) for its role in ruling out vascular abnormalities and potentially predicting ongoing bleeding. Its use is limited by the concern for contrast induced nephropathy (CIN); however, the magnitude of this risk is not known. Methods-We performed a retrospective analysis of a prospectively collected cohort of consecutive patients with ICH presenting to a single tertiary care hospital from 2002 to 2007. Demographic, clinical, and radiographic data were prospectively collected for all patients. Laboratory data and clinical course over the first 48 hours were retrospectively reviewed. Acute nephropathy was defined as any rise in creatinine of >25% or >0.5 mg/dL, such that the highest creatinine value was above 1.5 mg/dL. Results-539 patients presented during the study period and had at least 2 creatinine measurements. 348 (65%) received a CTA. Acute nephropathy developed in 6% of patients who received a CTA and in 10% of those who did not (P=0.1). Risk of nephropathy was 14% in those receiving no contrast (130 patients), 5% in those receiving 1 contrast study (124 patients), and 6% in those receiving >1 contrast study (244 patients). Neither CTA nor any use of contrast predicted nephropathy in univariate or multivariate analysis. Conclusion-The risk of acute nephropathy after ICH was not increased by use of CTA. Studies of CIN that do not include a control group may overestimate the influence of contrast. Patients with ICH appear to have an 8% risk of developing "Hospital-Acquired Nephropathy."

The ECASS 3 trial demonstrated a statistically significant benefit of intravenous tissue plasminogen activator for acute cerebral ischemia in the 3- to 4.5-hour window, but an effect size estimate incorporating benefit and harm across all levels of poststroke disability has not previously been derived. Methods-Joint outcome table specification was used to derive number needed to treat to benefit (NNTB) and number needed to treat to harm (NNTH) values summarizing treatment impact over the entire outcome range on the modified Rankin scale of global disability, including both expert-dependent and expert-independent (algorithmic and repeated random sampling) array generation. Results-For the full 7-category modified Rankin scale, algorithmic analysis demonstrated that the NNTB for 1 additional patient to have a better outcome by >= 1 grades than with placebo must lie between 4.0 and 13.0. In bootstrap simulations, the mean NNTB was 7.1. Expert joint outcome table analyses indicated that the NNTB for improved final outcome was 6.1 (95% CI, 5.6-6.7) and the NNTH 37.5 (95% CI, 34.6-40.5). Benefit per 100 patients treated was 16.3 and harm per 100 was 2.7. The likelihood of help to harm ratio was 6.0. Conclusions-Treatment with tissue plasminogen activator in the 3- to 4.5-hour window confers benefit on approximately half as many patients as treatment <3 hours, with no increase in the conferral of harm. Approximately 1 in 6 patients has a better and 1 in 35 has a worse outcome as a result of therapy. (Stroke. 2009; 40: 2433-2437.)

In tandem, the developing infarct is exacerbated by influx of numerous inflammatory cell types, including T and B lymphocytes. These features of stroke prompted our use of recombinant T cell receptor ligands (RTL), partial major histocompatibility complex Class II molecules covalently bound to myelin peptides. We tested the hypothesis that RTL would improve ischemic outcome in the brain without exacerbating defects in the peripheral immune system function. Methods-Four daily doses of RTL were administered subcutaneously to C57BL/6 mice after middle cerebral artery occlusion, and lesion size and cellular composition were assessed in the brain and cell numbers were assessed in the spleen and thymus. Results-Treatment with RTL551 (I-A(b) molecule linked to MOG-35-55 peptide) reduced cortical and total stroke lesion size by approximately 50%, inhibited the accumulation of inflammatory cells, particularly macrophages/activated microglial cells and dendritic cells, and mitigated splenic atrophy. Treatment with RTL1000 (HLA-DR2 moiety linked to human MOG-35-55 peptide) similarly reduced the stroke lesion size in HLA-DR2 transgenic mice. In contrast, control RTL with a nonneuroantigen peptide or a mismatched major histocompatibility complex Class II moiety had no effect on stroke lesion size. Conclusions-These data are the first to demonstrate successful treatment of experimental stroke using a neuroantigen-specific immunomodulatory agent administered after ischemia, suggesting therapeutic potential in human stroke.

Accumulating evidence suggests that the presence of brain infarction, including silent infarction, influences the course of Alzheimer disease. Conversely, there is evidence that beta-amyloid can impair blood vessel function. Vascular beta-amyloid deposition, also known as cerebral amyloid angiopathy, is associated with vascular dysfunction in animal and human studies. Alzheimer disease is associated with morphological changes in capillary networks, and soluble beta-amyloid produces abnormal vascular responses to physiological and pharmacological stimuli. In this review, we discuss current evidence linking beta-amyloid metabolism with vascular function and morphological changes in animals and humans. (Stroke. 2009; 40: 2601-2606.)

The purpose of this study was to examine the relationship between patient quality of life and distress. Data from 50 GBM patients presenting to a neuro-oncology clinic were evaluated. Descriptive statistics and correlations between the distress score and the FACT-Br subscale scores were generated. The mean distress score was 2.15 (std 2.66), and 28.9% of brain tumor patients identified a distress score of 4 or above. The mean FACT-Br total was 127.34 (std 21.29), with patients scoring lowest in the EWB (18.95 std 4.4) and FWB (15.06 std 6.80) subscales. No differences between demographic groups were identified with regard to distress or quality of life. Statistically significant correlations were identified between the distress score and the SWB (R = -0.46, P = 0.001) and EWB (R = -0.56, P = 0.001) subscales of the FACT-Br. Fifty percent of participants who did not complete the FACT-Br reported clinically significant distress, but this did not differ significantly from participants who completed it. Assessment of distress in brain tumor patients provides clinically relevant information and suggests interventions that may support quality of life. Further research is needed to explore the relationship between distress and quality of life. Current approaches to measuring quality of life in brain tumor patients may systematically undersample patients with advanced illness or significant psychosocial distress.

TI The in-vitro effects of E5555, a protease-activated receptor (PAR)-1 antagonist, on platelet biomarkers in healthy volunteers and patients with coronary artery disease SO THROMBOSIS AND HAEMOSTASIS LA English DT Article DE E5555; PAR-1; thrombin receptor antagonists; platelets; aspirin; clopidogrel; in vitro; coronary artery disease ID ACUTE MYOCARDIAL-INFARCTION; THROMBIN RECEPTOR; CLOPIDOGREL; RESISTANCE; ASPIRIN AB E5555 is a potent protease-activated receptor (PAR-1) antagonist targeting the G-coupled receptor and modulating thrombinplatelet-endothelial interactions. The drug is currently being tested in phase 11 trials in patients with coronary artery disease (CAD) and has potential antithrombotic and anti-inflammatory benefits. We investigated the in-vitro effects of E5555 on platelet function beyond PAR-1 blockade in healthy volunteers and CAD patients treated with aspirin (ASA) with or without clopidogrel. Conventional aggregation induced by 5 mu M ADP, 1 mu g/ml collagen, 10 mu M TRAP, whole blood aggregation with 1 mu g/ml collagen, and expression of 14 intact, and TRAP-stimulated receptors by flow cytometry were utilised to assess platelet activity after preincubation with escalating concentrations of E5555 (20 ng/ml, 50 ng/ml, and 100 ng/ml) in healthy volunteers, CAD patients treated with ASA, and CAD patients treated with ASA and clopidogrel combination (n= 10,for each group). E5555 inhibited a number of platelet biomarkers. Platelet inhibition was usually moderate, present already at 20 ng/ml, and was not seemingly dose-dependent without TRAP stimulation. E5555 caused 10-15% inhibition of ADP- and collagen-induced platelet aggregation in plasma, but not in whole blood. TRAP-induced aggregation was inhibited almost completely. PECAM-1, GP IIb/IIIa antigen, and activity with PAC-1, GPIb, thrombospondin, vitronectin receptor expression, and formation of platelet-monocyte aggregates were also significantly reduced by E5555. TRAP stimulation caused dose-dependent effects between 20 and 50 ng/ml E5555 doses. P-selectin, LAMP-1, LAMP, and CD40-ligand were not affected by E5555. In conclusion, E5555 in vitro moderately but significantly inhibits platelet activity beyond PAR-1 blockade. Antiplatelet potency of ASA alone, and the combination of ASA and clopidogrel may be enhanced by E5555 providing rationale for their synergistic use. Selective blockade of platelet receptors suggests unique antiplatelet properties of E5555 as a potential addition to current antithrombotic regimens.

The utility of fine-needle aspiration biopsy (FNAB) for this purpose requires a low false-negative (FN) rate and an acceptable sensitivity and specificity for the detection of malignancy. While reviewing our institution's experience with thyroid FNAB, we found significant discrepancies in how statistics of thyroid FNAB were tabulated and reported in the literature. Here we examine the sources of these discrepancies by evaluating large series of thyroid FNAB with regard to cytopathologic reporting and statistical calculation. Methods: Published series of thyroid FNAB with >200 FNAB and available histological data with sufficient raw data to recalculate statistics were analyzed. Considering indeterminate and malignant results to be positive FNAB results, since, in a four-tier system, both lead to surgical management, specificity, sensitivity, accuracy, positive predictive value, negative predictive value, FN, and false-positive (FP) rates were recalculated. Differences between reported and recalculated statistics were then evaluated for significance. Results: Nineteen studies and 20 series were identified. The following are reported and recalculated means, respectively: for sensitivity, 81% and 86%; for specificity, 81% and 62%; for accuracy, 77% and 71%; for positive predictive value, 65% and 50%; for negative predictive value, 84% and 93%; for FN rates, 13% and 14%; for FP rates, 10% and 38%. FP rates had a mean of 1.4% when recalculated considering only malignant FNAB as positive tests. Specificity and FP rates had statistically significant differences between the means of reported and recalculated values. Conclusions: Thyroid FNAB remains the screening tool of choice in the evaluation of thyroid nodules. However, the variability in the calculation of reported thyroid FNAB statistics highlights the need for uniformity in statistical reporting for accurate understanding of thyroid FNAB's clinical utility.

Brain stimulation can target a local brain area causally, but without revealing the entire network affected. Combining brain stimulation with concurrent neuroimaging allows a new causal approach to how interplay between extended networks of brain regions can support cognition. Brain stimulation does not affect only the targeted local region but also activity in remote interconnected regions. These remote effects depend on cognitive factors (e.g. task-condition), revealing dynamic changes in interplay between brain areas. We illustrate this with examples from top-down modulation of visual cortex, response-competition, interhemispheric rivalry and motor tasks; but the new approach should be applicable to many domains of cognition.

Current treatments focus on blocking neurotransmission and have resulted in limited success. Recent progress points to an important role of neuroinflammation in the pathogenesis of neuropathic pain. Matrix metalloproteases (MMPs) comprise a large family of zinc endopeptidases that have been implicated in the generation of neuroinflammation via cleavage of extracellular matrix proteins and activation of proinflammatory cytokines and chemokines. However, little is known about the role of MMPs in chronic pain regulation. Our recent study has shown that neuropathic pain development in the early and late phase requires MMP-9 and MMP-2, respectively. Inhibition of MMP-9 or MMP-2 might provide a new strategy for the prevention and treatment of neuropathic pain.

TI Suppression of IFN gamma plus mycobacterial lipoarabinomannan-induced NO by IL-4 is due to decreased IRF-1 expression SO TUBERCULOSIS LA English DT Article DE Lipoarabinomannan; Nitric oxide; Interleukin-4; Inducible nitric oxide synthase; Interferon-gamma; Transcriptional regulation ID NITRIC-OXIDE SYNTHASE; TUMOR-NECROSIS-FACTOR; GROWTH-FACTOR-BETA; NF-KAPPA-B; HUMAN PULMONARY TUBERCULOSIS; RAT-LIVER ARGINASE; INTERFERON-GAMMA; FACTOR-ALPHA; ALTERNATIVE ACTIVATION; MURINE MACROPHAGES AB In mice, and possibly in humans, nitric oxide (NO) is an important host-defense molecule against Mycobacterium tuberculosis. Inducible nitric oxide synthase (iNOS) and NO are upregulated in murine macrophages stimulated with interferon-gamma (IFN gamma) and mannose-capped lipoarabinomannan (ManLAM), a major lipoglycan in the cell wall of M. tuberculosis. Interleukin-4 (IL-4) can inhibit NO expression and may impair host immune response to M. tuberculosis. Therefore, we sought to determine the mechanism by which IL-4 inhibits IFN gamma + ManLAM-induced NO production. Since L-arginine is the substrate for both iNOS and arginase, and IL-4 increases arginase activity by inducing its production, a plausible mechanism of IL-4 inhibition of NO expression is via depletion of L-arginine through increased arginase activity. Herein, we show that IL-4 inhibited iNOS gene expression at the transcriptional level, suggesting an inhibitory mechanism that is independent of the competition for L-arginine between iNOS and arginase. Furthermore, pharmacologic inhibition of IL-4-induced arginase activity did not abrogate IL-4 inhibition of IFN gamma + ManLAM-induced NO expression. Instead, inhibition by IL-4 was mediated principally by the ability of IL-4 to inhibit the production of IFN gamma-induced interferon-gamma response factor-1 (IRF-1) protein, a critically important transcriptional element that enhances expression of IFN gamma-inducible genes such as iNOS.

TI Three-dimensional ultrasound detection of abnormally located intrauterine contraceptive devices which are a source of pelvic pain and abnormal bleeding SO ULTRASOUND IN OBSTETRICS & GYNECOLOGY LA English DT Article DE 3D ultrasound; IUD; pelvic pain ID SONOGRAPHY; UTERUS AB Objective To determine whether intrauterine contraceptive devices (IUDs) that are located abnormally within the myometrium or cervix cause a higher incidence of pelvic pain and abnormal bleeding compared with normally positioned devices. Methods Over a period of 9 months, all patients with an IUD presenting at our unit for two-dimensional pelvic ultrasound underwent a three-dimensional (3D) volume reconstruction of the coronal view, to visualize the entire IUD within the cavity. The IUD was deemed malpositioned if any part extended past the cavity, into the myometrium or cervix. The indications for ultrasound were recorded at presentation for the exam. The presenting symptoms of patients with an abnormally located IUD were compared with those with normally positioned ones. Results Among 167 consecutive patients with an IUD evaluated using the 3D reconstructed coronal view, 28 (16.8%) bad an IUD with side arms abnormally located within the myometrium. The abnormal positioning of the IUD arms was only detected using the 3D coronal view. A higher proportion of patients with an abnormally located IUD presented with bleeding (35.7%) or pain (39.3%) compared with those with normally positioned IUDs (15.1% with bleeding and 19.4% with pain) (P = 0.02 and 0.03, respectively). Seventy-five Percent of Patients with an abnormally located IUD presented with bleeding or pain compared with 34.5% of those whose IUD was normally placed (P = 0.0001). Twenty of 21 patients with an abnormally located IUD presenting with pelvic pain or bleeding reported improvement in their symptoms after IUD removal. Conclusion A 3D coronal view of the uterus is useful in the visualization of IUDs. The coronal view showing the entire device and its position within the uterus may help in identifying the cause of pelvic pain and bleeding in patients with an embedded IUD. Copyright (c) 2009 ISUOG.

In order to assess the cellular basis of immune activation, immunohistochemistry was applied to the analysis of inflammatory cell subsets in situ in 13 patients with NF. The percentage of inflammatory cells in skin and soft tissue was scored from 0 to 3+ (> 50%). Substantial numbers of CD15+ polymorphonuclear leukocytes were present in 12 of 13 patients. CD3+ T-lymphocytes accounted for > 10%, CD68+ macrophages for > 50%, and Factor XIIIa+ mononuclear cells for > 10% of the mononuclear cell infiltrates, respectively, in 10 of 13 patients, whereas CD1a+ cells were present in only 3 of 13 cases and accounted for < 10% of mononuclear inflammatory cells. We conclude that immune lymphocytes and accessory immune cells are represented in substantial numbers in the early lesions of NF, and their presence supports current concepts with respect to the pathophysiology of this disorder.

TI The International Xenotransplantation Association consensus statement on conditions for undertaking clinical trials of porcine islet products in type 1 diabetes - Chapter 1: Key ethical requirements and progress toward the definition of an international regulatory framework SO XENOTRANSPLANTATION LA English DT Article DE ethics; islets of Langerhans; regulation; xenotransplantation ID NONHUMAN-PRIMATES; SELECTION AB The outstanding results recently obtained in islet xenotransplantation suggest that porcine islet clinical trials may soon be scientifically appropriate. Before the initiation of such clinical studies, however, it is essential that a series of key ethical and regulatory conditions are satisfied. As far as ethics is concerned, the fundamental requirements have been previously reported in a position paper of the Ethics Committee of the International Xenotransplantation Association. These include aspects related to the selection of adequately informed, appropriate recipients; animal breeding and welfare; safety issues and the need for a favorable risk/benefit assessment based on strong efficacy data in relevant xenotransplantation studies in the primate. As most diabetic patients are not at risk of short-term mortality without islet transplantation, only a small subset of patients could currently be considered for any type of islet transplant. However, there are potential advantages to xenotransplantation that could result in a favorable benefit-over-harm determination for islet xenotransplantation in this subpopulation and ultimately in a broader population of diabetic patients. With regard to regulatory aspects, the key concepts underlying the development of the regulatory models in existence in the United States, Europe and New Zealand are discussed. Each of these models provides an example of a well-defined regulatory approach to ensure the initiation of well-regulated and ethically acceptable clinical islet xenotransplantation trials. At this stage, it becomes apparent that only a well-coordinated international effort such as that initiated by the World Health Organization, aimed at harmonizing xenotransplantation procedures according to the highest ethical and regulatory standards on a global scale, will enable the initiation of clinical xenotransplantation trials under the best auspices for its success and minimize any risk of failure.

Contraction of the tensor tympani in response to both auditory and non-auditory stimulation is mediated by the tensor tympani motoneurons (TTMNs). There are interesting differences among species in the acoustic thresholds for contraction of the middle ear muscles, which may be a reflection of underlying anatomical differences such as the number of TTMNs. However anatomical data for mice are lacking, even though the mouse is becoming the most common animal model for auditory and neuroscience research. We investigated the number and morphology of TTMNs in mice using Fluorogold, a retrograde neuronal tracer. After injections of Fluorogold into the tensor tympani muscle, a column of labeled TTMNs was identified ventro-lateral to the ipsilateral trigeminal nucleus. The labeled TTMNs were classified according to their morphological characteristics into three subtypes: "octopus-like", "fusiform" and "stellate", suggesting underlying differences in function. All three subtypes formed sparsely branched and radiating dendrites, some longer than 600 mu m. Dendrites were longest and most numerous in the dorso-medial direction. In 18 cases, the mean number of mouse TTMNs was 51; the largest numbers were 70, 74 and 90 (n = 3 injections). The mean size of mouse TTMNs was 13.0 mu m (minor axis) and 23.5 mu m (major axis). Compared with studies of TTMNs in larger species (cats and rats), mouse TTMNs are both fewer in number and smaller in size. (C) 2009 Elsevier B.V. All rights reserved.

We hypothesized that there may be differences in levels of excitatory amino acid neurotransmitters and/or their derivatives in migraine group based on their increased sensitivity to pain. Methods: 2D J-resolved proton magnetic resonance spectroscopy ((1)H-MRS) data were acquired at 4.0 Tesla (T) from the ACC and insula in 10 migraine patients (7 women, 3 men, age 43 +/- 11 years) and 8 age gender matched controls (7 women, 3 men, age 41 +/- 9 years). Results: Standard statistical analyses including analysis of variance (ANOVA) showed no significant metabolite differences between the two subject cohorts in the ACC nor the insula. However, linear discriminant analysis (LDA) introduced a clear separation between subject cohorts based on N-acetyl aspartylglutamate (NAAG) and glutamine (Gln) in the ACC and insula. Conclusion: These results are consistent with glutamatergic abnormalities in the ACC and insula in migraine patients during their interictal period compared to healthy controls. An alteration in excitatory amino acid neurotransmitters and their derivatives may be a contributing factor for migraineurs for a decrease in sensitivity for migraine or a consequence of the chronic migraine state. Such findings, if extrapolated to other regions of the brain would offer new opportunities to modulate central system as interictal or preemptive medications in these patients.

Accordingly, we studied how the pattern of firing of primary afferent influences NK1R internalization. In rat spinal cord slices, electrical stimulation of the dorsal root evoked NK1R internalization in lamina I neurons by inducing substance P release from primary afferents. The stimulation frequency had pronounced effects on NK1R internalization, which increased up to 100 Hz and then diminished abruptly at 200 Hz. Peptidase inhibitors increased NK1R internalization at frequencies below 30 Hz, indicating that peptidases limit the access of substance P to the receptor at moderate firing rates. NK1R internalization increased with number of pulses at all frequencies, but maximal internalization was substantially lower at 1-10 Hz than at 30 Hz. Pulses organized into bursts produced the same NK1R internalization as sustained 30 Hz stimulation. To determine whether substance P release induced at high stimulation frequencies was from C-fibers, we recorded compound action potentials in the sciatic nerve of anesthetized rats. We observed substantial NK1R internalization when stimulating at intensities evoking a C-elevation, but not at intensities evoking only an A delta-elevation. Each pulse in trains at frequencies up to 100 Hz evoked a C-elevation, demonstrating that C-fibers can follow these high frequencies. C-elevation amplitudes declined progressively with increasing stimulation frequency, which was likely caused by a combination of factors including temporal dispersion. In conclusion, the instantaneous firing frequency in C-fibers determines the amount of substance P released by noxious stimuli. Published by Elsevier Ltd on behalf of IBRO.

Chromosomal translocations are hallmarks of several tumor types where they are thought to have arisen in stem or precursor cells. Although approaches exist to study factors involved in translocation formation in mouse cells, approaches in human cells have been lacking, especially in relevant cell types. The technology of zinc finger nucleases (ZFNs) allows DNA double-strand breaks (DSBs) to be introduced into specified chromosomal loci. We harnessed this technology to induce chromosomal translocations in human cells by generating concurrent DSBs at 2 endogenous loci, the PPP1R12C/p84 gene on chromosome 19 and the IL2R gamma gene on the X chromosome. Translocation breakpoint junctions for t(19;X) were detected with nested quantitative PCR in a high throughput 96-well format using denaturation curves and DNA sequencing in a variety of human cell types, including embryonic stem (hES) cells and hES cell-derived mesenchymal precursor cells. Although readily detected, translocations were less frequent than repair of a single DSB by gene targeting or nonhomologous end-joining, neither of which leads to gross chromosomal rearrangements. While previous studies have relied on laborious genetic modification of cells and extensive growth in culture, the approach described in this report is readily applicable to primary human cells, including mutipotent and pluripotent cells, to uncover both the underlying mechanisms and phenotypic consequences of targeted translocations and other genomic rearrangements.

TI Universal behavior of the osmotically compressed cell and its analogy to the colloidal glass transition SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE compression; cytoplasm; cytoskeleton; mechanotransduction; stiffness ID AIRWAY SMOOTH-MUSCLE; LIVING CELL; VOLUME; STIFFNESS; LIQUIDS; STRESS; VISCOELASTICITY; CYTOSKELETON; MECHANICS; DYNAMICS AB Mechanical robustness of the cell under different modes of stress and deformation is essential to its survival and function. Under tension, mechanical rigidity is provided by the cytoskeletal network; with increasing stress, this network stiffens, providing increased resistance to deformation. However, a cell must also resist compression, which will inevitably occur whenever cell volume is decreased during such biologically important processes as anhydrobiosis and apoptosis. Under compression, individual filaments can buckle, thereby reducing the stiffness and weakening the cytoskeletal network. However, the intracellular space is crowded with macromolecules and organelles that can resist compression. A simple picture describing their behavior is that of colloidal particles; colloids exhibit a sharp increase in viscosity with increasing volume fraction, ultimately undergoing a glass transition and becoming a solid. We investigate the consequences of these 2 competing effects and show that as a cell is compressed by hyperosmotic stress it becomes progressively more rigid. Although this stiffening behavior depends somewhat on cell type, starting conditions, molecular motors, and cytoskeletal contributions, its dependence on solid volume fraction is exponential in every instance. This universal behavior suggests that compression-induced weakening of the network is overwhelmed by crowding-induced stiffening of the cytoplasm. We also show that compression dramatically slows intracellular relaxation processes. The increase in stiffness, combined with the slowing of relaxation processes, is reminiscent of a glass transition of colloidal suspensions, but only when comprised of deformable particles. Our work provides a means to probe the physical nature of the cytoplasm under compression, and leads to results that are universal across cell type. C1 [Zhou, E. H.; Trepat, X.; Park, C.

TI Targeting Tim-1 to overcome resistance to transplantation tolerance mediated by CD8 T17 cells SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE costimulation; IL-17; rejection; immunosuppression ID CARDIAC ALLOGRAFT-REJECTION; T-CELLS; IFN-GAMMA; TH17 CELLS; BLOCKADE-RESISTANT; TUMOR-GROWTH; IN-VIVO; IL-17; INTERLEUKIN-17; MICE AB The ability to induce durable transplantation tolerance predictably and consistently in the clinic is a highly desired but elusive goal. Progress is hampered by lack of appropriate experimental models in which to study resistance to transplantation tolerance. Here, we demonstrate that T helper 1-associated T box 21 transcription factor (Tbet) KO recipients exhibit allograft tolerance resistance specifically mediated by IL-17-producing CD8 T (T17) cells. Neutralization of IL-17 facilitates long-term cardiac allograft survival with combined T cell co-stimulation (CD28-CD80/86 and CD154-CD40) blockade in Tbet KO recipients. We have used this T17-biased Tbet KO model of allograft tolerance resistance to study the impact of targeting a T cell-costimulatory pathway, and demonstrate that targeting T cell Ig and mucin domain-1 (Tim-1) with anti-Tim-1 overcomes this resistance by specifically inhibiting the pathogenic IL-17-producing CD8 T17 cells. These data indicate that in the absence of Th1 immunity, CD8 T17 alloreactivity constitutes a barrier to transplantation tolerance. Targeting TIM-1 provides an approach to overcome resistance to tolerance in clinical transplantation. C1 [Yuan, Xueli; Ansari, M.

We employed functional magnetic resonance imaging (fMRI) to compare patterns of regional brain activation in BPD patients and healthy volunteers as they process positive and negative social emotional stimuli. fMRI images were acquired while 19 BPD patients and 17 healthy controls (HC) viewed emotion-inducing pictures from the International Affective Pictures System set. Activation data were analyzed with SPM5 ANCOVA models to derive the effects of diagnosis and stimulus type. BPD patients demonstrated greater differences in activation than controls, when viewing negative pictures compared with rest, in the amygdala, fusiform gyrus, primary visual areas, superior temporal gyrus (STG), and premotor areas, while healthy controls showed greater differences than BPD patients in the insula, middle temporal gyrus and dorsolateral prefrontal cortex (BA46). When viewing positive pictures compared with rest, BPD patients showed greater differences in the STG, premotor cortex, and ventrolateral prefrontal cortex. These findings suggest that BPD patients show greater amygdala activity and heightened activity of visual processing regions relative to findings for HC subjects in the processing of negative social emotional pictures compared with rest. The patients activate neural networks in emotion processing that are phylogeneticall older and more reflexive than those activated by HC subjects. Published by Elsevier Ireland Ltd.

Methods: 39 cases of BC in 28 HL survivors were retrospectively reviewed. 21 patients were included in a case-control analysis. Results: The median age at diagnosis of HL and BC was 25.3 and 45.3 years, respectively. The median interval to develop BC was 16.1 years. Eleven women (39.2%) had bilateral disease. Mode of detection of the index breast cancers was by mammographic screening in 17 patients (60.7%), palpable lump in 8 patients (28.6%), clinical examination in two patients (7.1%), and unknown in one patient (3.6%). Case-control analysis showed that histological features and prognosis of BC after HL were similar to those of primary BC, however, for BC after HL, mastectomy was the predominant surgery (P = .001) and adjuvant radiotherapy and anthracycline-based chemotherapy were less frequently used as compared to primary BC (P < .001 and .003, respectively). Conclusion: The previous history of HL does not appear to be a poor prognostic factor for BC occurring thereafter. C1 [El-Din, Mohamed A.

TI A Comprehensive Approach to Identification of Surface-Exposed, Outer Membrane-Spanning Proteins of Leptospira interrogans SO PLOS ONE LA English DT Article AB Leptospirosis is a zoonosis with worldwide distribution caused by pathogenic spirochetes belonging to the genus Leptospira. The leptospiral life cycle involves transmission via fresh water and colonization of the renal tubules of their reservoir hosts or infection of accidental hosts, including humans. Bacterial outer membrane proteins (OMPs), particularly those with surface-exposed regions, play crucial roles in virulence mechanisms of pathogens and the adaptation to various environmental conditions, including those of the mammalian host. Little is known about the surface-exposed OMPs in Leptospira, particularly those with outer membrane-spanning domains. Herein, we describe a comprehensive strategy for identification and characterization of leptospiral transmembrane OMPs. The genomic sequence of L. interrogans serovar Copenhageni strain Fiocruz L1-130 allowed us to employ the beta-barrel prediction programs, PRED-TMBB and TMBETA-NET, to identify potential transmembrane OMPs. Several complementary methods were used to characterize four novel OMPs, designated OmpL36, OmpL37, OmpL47 and OmpL54. In addition to surface immunofluorescence and surface biotinylation, we describe surface proteolysis of intact leptospires as an improved method for determining the surface exposure of leptospiral proteins. Membrane integration was confirmed using techniques for removal of peripheral membrane proteins. We also demonstrate deficiencies in the Triton X-114 fractionation method for assessing the outer membrane localization of transmembrane OMPs. Our results establish a broadly applicable strategy for the elucidation of novel surface-exposed outer membrane-spanning proteins of Leptospira, an essential step in the discovery of potential virulence factors, diagnostic antigens and vaccine candidates.

EC remains a little understood condition in contrast to the increasingly recognized eosinophilic esophagitis. Clinical presentation of EC is highly variable according to mucosal, transmural, or serosal predominance of inflammation. EC has a broad differential diagnosis because colon tissue eosinophilia often occurs in parasitic infection, drug-induced allergic reactions, inflammatory bowel disease, and various connective tissue disorders, which require thorough searching for secondary causes that may be specifically treated with antibiotics or dietary and drug elimination. Like eosinophilic gastrointestinal disease involving other segments of the gastrointestinal tract, EC responds very well to steroids that may be spared by using antihistamines, leukotriene inhibitors and biologics.

We found that the specialized knowledge of mental health clinicians and physicians, committed to the evaluation and management of transplant recipients, is essential for the optimal care of these patients who require a life-long regimen of immunosuppressive medication and dependency on the transplant team. Critical issues requiring psychiatric input are frequently encountered in the following areas (1) patient selection and informed consent; (2) recognition and pretransplant treatment of psychiatric disorders; (3) substance or alcohol abuse; (4) compliance with medical regimens; (5) posttransplant psychosis; and (6) immunosuppressive/psychiatric drug-drug interactions. This review focuses on the priorities in psychological and psychiatric care of these unique patients. C1 [Surman, Owen S.; Cosimi, A.

Targeted gene disruption studies have established that JNK-c-Jun signaling plays a vital role in stress-induced apoptosis. The oncogenic phosphatase Wip1 acts as an important regulator in DNA damage pathway by dephosphorylating a spectrum of proteins including p53, p38, Chk1, Chk2, and ATM. In this study we show that Wip1 negatively regulates the activation of MKK4-JNK-c-Jun signaling during stress-induced apoptosis. The loss of Wip1 function sensitizes mouse embryonic fibroblasts to stress-induced apoptosis via the activation of both p38-ATF2 and JNK-c-Jun signaling. Here we reveal that Wip1 has dual roles in alternatively regulating stress- and DNA damage-induced apoptosis through p38/JNK MAPKs and p38/p53-dependent pathways, respectively. Our results point to Wip1 as a general regulator of apoptosis, which further supports its role in tumorigenesis.

We performed cell-based vaccination in 2 tumor models. First, we vaccinated C57BL/6 mice lacking either GM-CSF, IL-5, or beta-common chain (beta c), a receptor subunit essential for GM-CSF and IL-5 signaling, with melanoma cells engineered to produce GM-CSF. Tumor vaccination was effective in both GM-CSF(-/-) and IL-5(-/-) mice, showing that protective immunization is independent of both endogenous cytokines. However, all beta c(-/-) animals developed tumor. Loss of tumor immunity in beta c(-/-) mice does not reflect global impairment in cell-mediated immunity, as contact hypersensitivity reaction to haptens is unaltered. The importance of tumor cell-derived GM-CSF was highlighted by recruitment of dendritic cells at the vaccination site in wildtype, GM-CSF(-/-), and IL-5(-/-) but not in beta c(-/-) mice. In the second model, vaccination with unmodified RENCA cells showed similar results with efficient immunization in BALB/c wild-type and GM-CSF(-/-), whereas all beta c(-/-) animals died. Altogether, our results strongly suggest that although endogenous GM-CSF and IL-5 are not required to induce tumor immunity, signaling through beta c receptor is critically needed for efficient cancer vaccination in both genetically modified GM-CSF-secreting tumor cells and a spontaneously immunogenic models.

Nevertheless, little is known about the characteristics of MM at the epigenetic level and specifically how microRNAs regulate MM progression in the context of the bone marrow milieu. Therefore, we performed microRNA expression profiling of bone marrow derived CD138(+) MM cells versus their normal cellular counterparts and validated data by qRT-PCR. We identified a MM-specific microRNA signature characterized by down-expression of microRNA-15a/-16 and overexpression of microRNA-222/-221/-382/-181a/-181b (P < .01). We investigated the functional role of microRNA-15a and -16 and showed that they regulate proliferation and growth of MM cells in vitro and in vivo by inhibiting AKT serine/threonineprotein-kinase (AKT3), ribosomal-protein-S6, MAP-kinases, and NF-kappa B-activator MAP3KIP3. Moreover, miRNA-15a and -16 exerted their anti-MM activity even in the context of the bone marrow milieu in vitro and in vivo. These data indicate that microRNAs play a pivotal role in the biology of MM and represent important targets for novel therapies in MM.

TI Cytomorphologic Features of Poorly Differentiated Thyroid Carcinoma A Multi-Institutional Analysis of 40 Cases SO CANCER CYTOPATHOLOGY LA English DT Article DE fine-needle aspiration; thyroid; insular; poorly differentiated; carcinoma ID FINE-NEEDLE-ASPIRATION; INSULAR CARCINOMA; CYTOLOGIC FEATURES; INTACT INSULAE; BIOPSY; GLAND; CYTOPATHOLOGY; STRUMA AB BACKGROUND: Poorly differentiated thyroid carcinoma (PDTC) is an uncommon and aggressive malignancy. Despite the significant clinical implications of a diagnosis of PDTC, its cytomorphologic features have not been well defined. Statistical analysis was applied to a series of 40 PDTCs to identify a specific set of cytomorphologic features that characterized these tumors on fine-needle aspiration biopsy (FNAB). METHODS: In total, 40 thyroid FNABs that were highly diagnosed histologically as PDTC (19 insular carcinomas and 21 noninsular carcinomas) comprised the study group. A control group of 40 well differentiated thyroid neoplasms were selected for comparison. All FNABs were reviewed and scored for a series of 32 cytomorphologic features. The results were evaluated using univariate and stepwise logistic regression (SLR) analyses. RESULTS: In univariate analysis, 17 cytomorphologic features were identified that characterized the 40 PDTCs: insular, solid, or trabecular cytoarchitecture (P < .001); high cellularity (P = .007); necrosis (P = .025) or background debris (P = .025); plasmacytoid appearance (P = .0007); single cells (P < .0001); high nuclear/cytoplasmic ratio (P < .0001); scant cytoplasm (P = .03); nuclear atypia (P < .0001), including nuclear pleomorphism (P = .0052) and anisokaryosis (P < .0001); granular/coarse chromatin (P = .026); naked nuclei (P = .01); mitotic activity (P = .0001) and apoptosis (P < .0001); endothelial wrapping (P = .0053); and severe crowding (P < .0001). In logistic regression analysis, severe crowding (P = .0008) and cytoarchitecture (P < .0001) were identified as the most significant cytomorphologic features of PDTCs, and the combination of cytoarchitecture, severe crowding, single cells, and high nuclear/cytoplasmic ratio was the most predictive of PDTC. CONCLUSIONS: PDTCs have characteristic cytomorphologic features. By using logistic regression analysis, the features that were identified as the most predictive of PDTC were severe crowding, insular/solid/trabecular morphology, single cells, and high nuclear/cytoplasmic ratio.

An accurate diagnosis is challenging, because endoscopic ultrasound (EUS) and cyst fluid analysis for carcinoembryonic antigen (CEA) and cytology have low sensitivity and specificity. Currently, molecular analysis is a commercially available test that promises an accurate diagnosis. The objective of the current study was to correlate a commercially provided molecular diagnosis (MDx) with a clinical consensus diagnosis (CCD) in the general categories of malignant, benign mucinous, and benign nonmucinous pancreatic cysts. METHODS: Pancreatic cysts that had aspirated fluid submitted for a commercially available molecular test (PathFinderTG) were reviewed. The CCD, defined by histology, malignant cytology, or 2 concordant tests (such as EUS, cytology, or CEA >= 192 ng/mL for mucinous cysts), was categorized as malignant, benign mucinous, or benign nonmucinous cyst in 35 patients. Their MDx, based on the PathFinderTG report, including analysis of k-ras mutation, loss of heterozygosity, and quantity/quality of DNA, also was classified as malignant, benign mucinous, or benign nonmucinous cyst. These 2 diagnoses were compared and correlated. RESULTS: The concordance between CCD and MDx was 5 of 6 (83%),13 of 15 (87%), and 13 of 14 (93%), respectively, for malignant, benign mucinous, and benign nonmucinous cysts, with an overall Cohen kappa statistic of 0.816. The sensitivity, specificity, and positive predictive value of the MDx were 83%, 100%, and 100%, respectively, for a malignant cyst and 86%, 93%, and 95%, respectively for a benign mucinous cyst. CONCLUSIONS: Molecular analysis of pancreatic cyst fluid adds diagnostic value to the preoperative diagnosis with high sensitivity, specificity, and positive predictive value for the diagnosis of malignant and benign mucinous pancreatic cysts.

Genomic instability in somatic cells increases with age, and this decline in somatic maintenance might be regulated to facilitate resource reallocation towards reproduction at the expense of cellular senescence. Here we show that Caenorhabditis elegans mutants with increased longevity exhibit a soma-to-germline transformation of gene expression programs normally limited to the germ line. Decreased insulin-like signalling causes the somatic misexpression of the germline-limited pie-1 and pgl family of genes in intestinal and ectodermal tissues. The forkhead boxO1A (FOXO) transcription factor DAF-16, the major transcriptional effector of insulin-like signalling, regulates pie-1 expression by directly binding to the pie-1 promoter. The somatic tissues of insulin-like mutants are more germline-like and protected from genotoxic stress. Gene inactivation of components of the cytosolic chaperonin complex that induce increased longevity also causes somatic misexpression of PGL-1. These results indicate that the acquisition of germline characteristics by the somatic cells of C. elegans mutants with increased longevity contributes to their increased health and survival.

Here, using integrative analysis of a genomic profile of the region, we identify a Golgi protein, GOLPH3, as a candidate targeted for amplification. Gain- and loss-of-function studies in vitro and in vivo validated GOLPH3 as a potent oncogene. Physically, GOLPH3 localizes to the trans- Golgi network and interacts with components of the retromer complex, which in yeast has been linked to target of rapamycin ( TOR) signalling. Mechanistically, GOLPH3 regulates cell size, enhances growth-factor-induced mTOR (also known as FRAP1) signalling in human cancer cells, and alters the response to an mTOR inhibitor in vivo. Thus, genomic and genetic, biological, functional and biochemical data in yeast and humans establishes GOLPH3 as a new oncogene that is commonly targeted for amplification in human cancer, and is capable of modulating the response to rapamycin, a cancer drug in clinical use.

One such gene is Down's syndrome candidate region-1 (DSCR1, also known as RCAN1), which encodes a protein that suppresses vascular endothelial growth factor ( VEGF)mediated angiogenic signalling by the calcineurin pathway(5-10). Here we show that DSCR1 is increased in Down's syndrome tissues and in a mouse model of Down's syndrome. Furthermore, we show that the modest increase in expression afforded by a single extra transgenic copy of Dscr1 is sufficient to confer significant suppression of tumour growth in mice, and that such resistance is a consequence of a deficit in tumour angiogenesis arising from suppression of the calcineurin pathway. We also provide evidence that attenuation of calcineurin activity by DSCR1, together with another chromosome 21 gene Dyrk1a, may be sufficient to markedly diminish angiogenesis. These data provide a mechanism for the reduced cancer incidence in Down's syndrome and identify the calcineurin signalling pathway, and its regulators DSCR1 and DYRK1A, as potential therapeutic targets in cancers arising in all individuals.

TI Biomechanical forces promote embryonic haematopoiesis SO NATURE LA English DT Article ID NITRIC-OXIDE SYNTHASE; STEM-CELLS; MOUSE EMBRYO; DEFINITIVE HEMATOPOIESIS; IN-VITRO; YOLK-SAC; EXPRESSION DEFINES; ENDOTHELIAL-CELLS; PROGENITOR CELLS; FLOW AB Biomechanical forces are emerging as critical regulators of embryogenesis, particularly in the developing cardiovascular system(1,2). After initiation of the heartbeat in vertebrates, cells lining the ventral aspect of the dorsal aorta, the placental vessels, and the umbilical and vitelline arteries initiate expression of the transcription factor Runx1 (refs 3-5), a master regulator of haematopoiesis, and give rise to haematopoietic cells(4). It remains unknown whether the biomechanical forces imposed on the vascular wall at this developmental stage act as a determinant of haematopoietic potential(6). Here, using mouse embryonic stem cells differentiated in vitro, we show that fluid shear stress increases the expression of Runx1 in CD41(+)c-Kit(+) haematopoietic progenitor cells(7), concomitantly augmenting their haematopoietic colony-forming potential. Moreover, we find that shear stress increases haematopoietic colony-forming potential and expression of haematopoietic markers in the para-aortic splanchnopleura/aorta-gonads-mesonephros of mouse embryos and that abrogation of nitric oxide, a mediator of shear-stress-induced signalling(8), compromises haematopoietic potential in vitro and in vivo. Collectively, these data reveal a critical role for biomechanical forces in haematopoietic development. C1 [Naveiras, Olaia; Wenzel, Pamela L.; McKinney-Freeman, Shannon; Lensch, M.

TI Long-term Outcomes in Individuals With Prolonged PR Interval or First-Degree Atrioventricular Block SO JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION LA English DT Article ID CORONARY HEART-DISEASE; ATRIAL-FIBRILLATION; RISK-FACTORS; NATURAL-HISTORY; WAVE DURATION; CONDUCTION; REGURGITATION; POPULATION; PROGNOSIS; FEATURES AB Context Prolongation of the electrocardiographic PR interval, known as first-degree atrioventricular block when the PR interval exceeds 200 milliseconds, is frequently encountered in clinical practice. Objective To determine the clinical significance of PR prolongation in ambulatory individuals. Design, Setting, and Participants Prospective, community-based cohort including 7575 individuals from the Framingham Heart Study (mean age, 47 years; 54% women) who underwent routine 12-lead electrocardiography. The study cohort underwent prospective follow-up through 2007 from baseline examinations in 1968-1974. Multivariable-adjusted Cox proportional hazards models were used to examine the associations of PR interval with the incidence of arrhythmic events and death. Main Outcome Measures Incident atrial fibrillation (AF), pacemaker implantation, and all-cause mortality. Results During follow-up, 481 participants developed AF, 124 required pacemaker implantation, and 1739 died. At the baseline examination, 124 individuals had PR intervals longer than 200 milliseconds. For those with PR intervals longer than 200 milliseconds compared with those with PR intervals of 200 milliseconds or shorter, incidence rates per 10 000 person-years were 140 (95% confidence interval [CI], 95-208) vs 36 (95% CI, 32-39) for AF, 59 (95% CI, 40-87) vs 6 (95% CI, 5-7) for pacemaker implantation, and 334 (95% CI, 260-428) vs 129 (95% CI, 123-135) for all-cause mortality. Corresponding absolute risk increases were 1.04% (AF), 0.53% (pacemaker implantation), and 2.05% (all-cause mortality) per year. In multivariable analyses, each 20-millisecond increment in PR was associated with an adjusted hazard ratio (HR) of 1.11 (95% CI, 1.02-1.22; P = .02) for AF, 1.22 (95% CI, 1.14-1.30; P < .001) for pacemaker implantation, and 1.08 (95% CI, 1.02-1.13; P = .005) for all-cause mortality. Individuals with first-degree atrioventricular block had a 2-fold adjusted risk of AF (HR, 2.06; 95% CI, 1.36-3.12; P < .001), 3-fold adjusted risk of pacemaker implantation (HR, 2.89; 95% CI, 1.83-4.57; P < .001), and 1.4-fold adjusted risk of all-cause mortality (HR, 1.44, 95% CI, 1.09-1.91; P = .01). Conclusion Prolongation of the PR interval is associated with increased risks of AF, pacemaker implantation, and all-cause mortality.

Here, we explored the role of CPXs in the mouse auditory system. Hearing was impaired in CPXI knock-out mice but normal in knock-out mice for CPXs II, III, IV, and III/IV as measured by auditory brainstem responses. Complexins were not detectable in cochlear hair cells but CPX I was expressed in spiral ganglion neurons (SGNs) that give rise to the auditory nerve. Ca(2+)-dependent exocytosis of inner hair cells and sound encoding by SGNs were unaffected in CPX I knock-out mice. In the absence of CPX I, the resting release probability in the endbulb of Held synapses of the auditory nerve fibers with bushy cells in the cochlear nucleus was reduced. As predicted by computational modeling, bushy cells had decreased spike rates at sound onset as well as longer and more variable first spike latencies explaining the abnormal auditory brainstem responses. In addition, we found synaptic transmission to outlast the stimulus at many endbulb of Held synapses in vitro and in vivo, suggesting impaired synchronization of release to stimulus offset. Although sound encoding in the cochlea proceeds in the absence of complexins, CPX I is required for faithful processing of sound onset and offset in the cochlear nucleus.

TI Suppression of Glomerulonephritis in NZB/NZW Lupus Prone Mice by Adoptive Transfer of Ex Vivo Expanded Regulatory T Cells SO PLOS ONE LA English DT Article AB Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown cause characterized by expansion of autoreactive lymphocytes. Regulatory T cells (T(regs)) are a component of the normal immune system and contribute to the maintenance of peripheral tolerance. T(reg) abnormalities have been associated with several autoimmune diseases and there is interest in the role of T(regs) in SLE. We previously demonstrated that transfer of expanded CD4(+)CD25(+)CD62L(HI) T(regs) slows the development of lupus in (NZBxNZW)F(1) (B/W) mice. However in the absence of T(reg) specific surface antigens, cell purification remains a compromise between the breadth and purity of the population isolated. Importantly, purified populations always contain Foxp3(-) effector T cells (T(effs)) that theoretically could exacerbate autoimmunity in the recipient. Here we explore the impact of transferring the more comprehensive, but less pure T(reg) subset defined by CD4(+)CD25(+) expression on development of murine lupus. All cells were FACS sorted and expanded prior to adoptive transfer. Development of proteinuria and survival were measured. We found that exogenous expansion of CD4(+)CD25(+) cells produced a population containing 70-85% CD4(+)Foxp3(+) T(regs). Expanded T(regs) had higher CTLA-4 and Foxp3 expression, increased in vitro suppression capacity, and prolonged in vivo survival as compared to freshly isolated cells. Adoptive transfer of expanded CD4(+)CD25(+) T(regs) inhibited the onset of glomerulonephritis and prolonged survival in mice. Importantly the population of T(eff) contained within the adoptively transferred cells had reduced survival and proliferation capacity as compared to either co-transferred T(regs) or transferred T(effs) expanded in the absence of T(regs). These studies demonstrate that adoptive transfer of expanded CD4(+)CD25(+)Foxp3(+) T(regs) has the capacity to inhibit the onset of murine lupus and that this capacity is significant despite transfer of co-cultured T(eff) cells. These data indicate that when co-expanded with regulatory T cells, exogenously activated T(effs) from autoimmune patients may not pose a significant risk of promoting disease.

Methods and Results-We examined clinical characteristics and risk factors at time of heart failure onset and long-term survival in Framingham Heart Study participants according to left ventricular ejection fraction <= 45% (n = 314; 59%) versus >45% (n = 220; 41%) and hierarchical causal classification. Heart failure was attributed to coronary heart disease in 278 participants (52%), valvular heart disease in 42 (8%), hypertension in 140 (26%), or other/unknown causes in 74 (14%). Multivariable predictors of HFPEF (versus HFREF) included elevated systolic blood pressure (odds ratio [OR] = 1.13 per 10 mm Hg; 95% confidence interval [CI], 1.04 to 1.22), atrial fibrillation (OR = 4.23; 95% CI, 2.38 to 7.52), and female sex (OR = 2.29; 95% CI, 1.35 to 3.90). Conversely, prior myocardial infarction (OR = 0.32; 95% CI, 0.19 to 0.53) and left bundle-branch block QRS morphology (OR = 0.21; 95% CI, 0.10 to 0.46) reduced the odds of HFPEF. Long-term prognosis was grim, with a median survival of 2.1 years (5-year mortality rate, 74%), and was equally poor in men and women with HFREF or HFPEF. Conclusions-Among community patients with new-onset heart failure, there are differences in causes and time-of-onset clinical characteristics between those with HFPEF versus HFREF. In people with HFREF, mortality is increased when coronary heart disease is the underlying cause. These findings suggest that heart failure with reduced left ventricular systolic function and heart failure with preserved left ventricular systolic function are partially distinct entities, with potentially different approaches to early detection and prevention.

Methods and Results-This was a phase II multicenter, randomized, placebo-controlled, double-blind trial of New York Heart Association class II to IV congestive heart failure patients randomized (2: 1) to DITPA or placebo and treated for 6 months. The study enrolled 86 patients (n = 57 to DITPA, n = 29 to placebo). The primary objective was to assess the effect of DITPA on a composite congestive heart failure end point that classifies patients as improved, worsened, or unchanged based on symptom changes and morbidity/mortality. DITPA was poorly tolerated, which obscured the interpretation of congestive heart failure-specific effects. Fatigue and gastrointestinal complaints, in particular, were more frequent in the DITPA group. DITPA increased cardiac index (by 18%) and decreased systemic vascular resistance (by 11%), serum cholesterol (-20%), low-density lipoprotein cholesterol (-30%), and body weight (-11 lb). Thyroid-stimulating hormone was suppressed in patients given DITPA, which reflects its thyromimetic effect; however, no symptoms or signs of potential hypothyroidism or thyrotoxicosis were seen. Conclusions-DITPA improved some hemodynamic and metabolic parameters, but there was no evidence for symptomatic benefit in congestive heart failure. (Circulation. 2009; 119: 3093-3100.)

TI Cost-effectiveness of Total Knee Arthroplasty in the United States Patient Risk and Hospital Volume SO ARCHIVES OF INTERNAL MEDICINE LA English DT Article ID TOTAL HIP; REPLACEMENT; OSTEOARTHRITIS; OUTCOMES; ARTHRITIS; HEALTH; SURGERY; UNCERTAINTY; ADULTS; MODEL AB Background: Total knee arthroplasty (TKA) relieves pain and improves quality of life for persons with advanced knee osteoarthritis. However, to our knowledge, the cost-effectiveness of TKA and the influences of hospital volume and patient risk on TKA cost-effectiveness have not been investigated in the United States. Methods: We developed a Markov, state-transition, computer simulation model and populated it with Medicare claims data and cost and outcomes data from national and multinational sources. We projected lifetime costs and quality-adjusted life expectancy (QALE) for different risk populations and varied TKA intervention and hospital volume. Cost-effectiveness of TKA was estimated across all patient risk and hospital volume permutations. Finally, we conducted sensitivity analyses to determine various parameters' influences on cost-effectiveness. Results: Overall, TKA increased QALE from 6.822 to 7.957 quality-adjusted life years (QALYs). Lifetime costs rose from $37 100 (no TKA) to $57 900 after TKA, resulting in an incremental cost-effectiveness ratio of $18 300 per QALY. For high-risk patients, TKA increased QALE from 5.713 to 6.594 QALY, yielding a cost-effectiveness ratio of $28 100 per QALY. At all risk levels, TKA was more costly and less effective in low-volume centers than in high-volume centers. Results were insensitive to variations of key input parameters within policy-relevant, clinically plausible ranges. The greatest variations were seen for the quality of life gain after TKA and the cost of TKA. Conclusions: Total knee arthroplasty appears to be cost-effective in the US Medicare-aged population, as currently practiced across all risk groups. Policy decisions should be made on the basis of available local options for TKA. However, when a high-volume hospital is available, TKAs performed in a high-volume hospital confer even greater value per dollar spent than TKAs performed in low-volume centers.

Metabolic changes in the frontal cortex, basal ganglia and white matter in 18 SIV-infected macaques were investigated using MRS during the first month of infection. Results: Changes in the N-acetylaspartate (NAA), choline (Cho), myo-inositol (MI), creatine (Cr) and glutamine/glutamate (Glx) resonances were quantified both in absolute terms and relative to the creatine resonance. Most abnormalities were observed at the time of peak viremia, 2 weeks post infection (wpi). At that time point, significant decreases in NAA and NAA/Cr, reflecting neuronal injury, were observed only in the frontal cortex. Cr was significantly elevated only in the white matter. Changes in Cho and Cho/Cr were similar across the brain regions, increasing at 2 wpi, and falling below baseline levels at 4 wpi. MI and MI/Cr levels were increased across all brain regions. Conclusion: These data best support the hypothesis that different brain regions have variable intrinsic vulnerabilities to neuronal injury caused by the AIDS virus.

This is accomplished by calculating a representative set of Pareto optimal solutions and storing them in a database. The structure of these representative Pareto sets is still not fully investigated. We propose two methods for a systematic analysis of multiobjective databases: principal component analysis and the isomap method. Both methods are able to extract the key trade-offs from a database and provide information which can lead to a better understanding of the clinical case and intensity-modulated radiation therapy planning in general.

TI Comparison of Sentinel Lymph Node Biopsy Alone and Completion Axillary Lymph Node Dissection for Node-Positive Breast Cancer SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article; Proceedings Paper CT 94th Annual Clinical Congress of the American-College-of-Surgeons/63rd Annual Sessions of the Owen H Wangensteen Forum on Fundamental Surgical Problems CY OCT 12-16, 2008 CL San Francisco, CA SP Amer Coll Surg ID FOLLOW-UP; CONTROLLED-TRIALS; TOTAL MASTECTOMY; ACOSOG Z0011; CARCINOMA; NOMOGRAM; IRRADIATION; WOMEN AB Purpose For women with breast cancer, the role of completion axillary lymph node dissection (ALND) after identification of nodal metastases by sentinel lymph node biopsy (SLNB) has been questioned. Our objectives were to assess national nodal evaluation practice patterns and to examine differences in recurrence and survival for SLNB alone versus SLNB with completion ALND. Patients and Methods From the National Cancer Data Base (1998 to 2005), women with clinically node-negative breast cancer who underwent SLNB and who had nodal metastases were identified. Practice patterns and outcomes were examined for patients who underwent SLNB alone versus SLNB with completion ALND (median follow-up, 63 months). Results Of 97,314 patients, 20.8% underwent SLNB alone, and 79.2% underwent SLNB with completion ALND. In 2004 to 2005, patients were significantly more likely to undergo SLNB alone if they were older, had smaller tumors, or were treated at non-National Cancer Institute-designated cancer centers. In patients with macroscopic nodal metastases (n = 20,075 during 1998 to 2000), there was a nonsignificant trend toward better outcomes for completion ALND (v SLNB alone) after analysis was adjusted for differences between the two groups: axillary recurrence (hazard ratio [HR], 0.58; 95% CI, 0.32 to 1.06) and overall survival (HR, 0.89; 95% CI, 0.76 to 1.04). In patients with microscopic nodal metastases (n = 2,203 during 1998 to 2000), there were no significant differences in axillary recurrence or survival for patients who underwent SLNB alone versus completion ALND. Conclusion Compared with SLNB alone, completion ALND does not appear to improve outcomes for breast cancer patients with microscopic nodal metastases; however, there was a nonsignificant trend toward better outcomes with completion ALND for those with macroscopic disease.

Patients and Methods IHC and/or FISH analyses were performed locally and required central confirmation as indicating HER2 positivity for trial entry. FISH data from the central HER2 analysis on patients in the 1-year trastuzumab and no trastuzumab arms were assessed in relation to disease-free survival (DFS) after a median 2 years of follow-up. Results Central FISH results were available for 2,071 (61%) of the 3,401 patients randomized to the 2 arms. Among patients with FISH-positive disease, (1) the hazard ratios for trastuzumab versus no trastuzumab were 0.56 (95% CI, 0.32 to 0.99) for locally IHC2+ cases (n = 340) and 0.80 (95% CI, 0.40 to 1.61) for centrally IHC2+ cases (n = 299). There was no significant prognostic relationship between (2a) HER2 FISH ratio, (2b) HER2 copy number, or (3) polysomy and DFS in the control arm or predictive relationship defining differential benefit from trastuzumab. Conclusion There was no evidence for reduced benefit of trastuzumab in HER2 IHC2+ FISH+ cases. The degree of HER2 amplification does not influence prognosis or benefit from adjuvant trastuzumab in patients treated with prior adjuvant chemotherapy. J Clin Oncol 27: 2962-2969.

Patients and Methods In a phase I/II study, 32 patients received four cycles of therapy consisting of: bevacizumab infusion (5 or 10 mg/kg) on day 1 of each cycle; fluorouracil infusion (225 mg/m(2)/24 hours) during cycles 2 to 4; external-beam irradiation (50.4 Gy in 28 fractions over 5.5 weeks); and surgery 7 to 10 weeks after completion of all therapies. We measured molecular, cellular, and physiologic biomarkers before treatment, during bevacizumab monotherapy, and during and after combination therapy. Results Tumors regressed from a mass with mean size of 5 cm (range, 3 to 12 cm) to an ulcer/scar with mean size of 2.4 cm (range, 0.7 to 6.0 cm) in all 32 patients. Histologic examination revealed either no cancer or varying numbers of scattered cancer cells in a bed of fibrosis at the primary site. This treatment resulted in an actuarial 5-year local control and overall survival of 100%. Actuarial 5-year disease-free survival was 75% and five patients developed metastases postsurgery. Bevacizumab with chemoradiotherapy showed acceptable toxicity. Bevacizumab decreased tumor interstitial fluid pressure and blood flow. Baseline plasma soluble vascular endothelial growth factor receptor 1 (sVEGFR1), plasma vascular endothelial growth factor (VEGF), placental-derived growth factor (PlGF), and interleukin 6 (IL-6) during treatment, and circulating endothelial cells (CECs) after treatment showed significant correlations with outcome. Conclusion Bevacizumab with chemoradiotherapy appears safe and active and yields promising survival results in locally advanced rectal cancer. Plasma VEGF, PlGF, sVEGFR1, and IL-6 and CECs should be further evaluated as candidate biomarkers of response for this regimen. J Clin Oncol 27: 3020-3026.

TI Efficacy, Safety, and Potential Biomarkers of Sunitinib Monotherapy in Advanced Hepatocellular Carcinoma: A Phase II Study SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID ENDOTHELIAL GROWTH-FACTOR; RECEPTOR TYROSINE KINASES; ADVANCED BREAST-CANCER; TUMOR ANGIOGENESIS; CLINICAL-TRIALS; MYELOID CELLS; THERAPY; EPIDEMIOLOGY; VASCULATURE; BEVACIZUMAB AB Purpose To assess the safety and efficacy of sunitinib in patients with advanced hepatocellular carcinoma (HCC) and explore biomarkers for sunitinib response. Patients and Methods We conducted a multidisciplinary phase II study of sunitinib, an antivascular endothelial growth factor receptor tyrosine kinase inhibitor, in advanced HCC. Patients received sunitinib 37.5 mg/d for 4 weeks followed by 2 weeks of rest per cycle. The primary end point was progression-free survival (PFS). We used functional magnetic resonance imaging to evaluate vascular changes in HCC after sunitinib treatment. Circulating molecular and cellular biomarkers were evaluated before and at six time points after sunitinib treatment. Results Thirty-four patients were enrolled. The objective response rate was 2.9%, and 50% of patients had stable disease. Median PFS was 3.9 months (95% CI, 2.6 to 6.9 months), and overall survival was 9.8 months (95% CI, 7.4 months to not available). Grade 3 or 4 toxicities included leukopenia/neutropenia, thrombocytopenia, elevation of aminotransferases, and fatigue. Sunitinib rapidly decreased vessel leakiness, and this effect was more pronounced in patients with delayed progression. When evaluated early (at baseline and day 14) as well as over three cycles of treatment, higher levels of inflammatory molecules (eg, interleukin-6, stromal-derived factor 1 alpha, soluble c-KIT) and circulating progenitor cells were associated with a poor outcome. Conclusion Sunitinib shows evidence of modest antitumor activity in advanced HCC with manageable adverse effects. Rapid changes in tumor vascular permeability and circulating inflammatory biomarkers are potential determinants of response and resistance to sunitinib in HCC. Our study suggests that control of inflammation might be critical for improving treatment outcome in advanced HCC. J Clin Oncol 27: 3027-3035.

Patients and Methods Patients with treatment-naive or relapsed/refractory disease achieving a complete response (CR), partial response (PR), or stable disease (SD) with four weekly rituximab infusions were randomly assigned to mitumprotimut-T/GM-CSF or placebo/GM-CSF, with doses given monthly for six doses, every 2 months for six doses, and then every 3 months until disease progression (PD). Randomization was stratified by prior therapy (treatment-naive or relapsed/refractory) and response to rituximab (CR/PR or SD). The primary end point was time to progression (TTP) from randomization. Results A total of 349 patients were randomly assigned; median age was 54 years, 79% were treatment naive, and 86% had stage III/IV disease. Median TTP was 9.0 months for mitumprotimut-T/GMCSF and 12.6 months for placebo/GM-CSF (hazard ratio [HR] = 1.384; P = .019). TTP was comparable between the two arms in treatment-naive patients (HR = 1.196; P = .258) and shorter with mitumprotimut-T/GM-CSF in relapsed/refractory disease (HR = 2.265; P = .004). After adjusting for Follicular Lymphoma International Prognostic Index (FLIPI) scores, the difference in TTP between the two arms was no longer significant. Overall objective response rate, rate of response improvement, and duration of response were comparable between the two arms. Toxicity was similar in the two arms; 76% of adverse events were mild or moderate, and 94% of patients had injection site reactions. Conclusion TTP was shorter with mitumprotimut-T/GM-CSF compared with placebo/GM-CSF. This difference was possibly due to the imbalance in FLIPI scores. J Clin Oncol 27: 3036-3043.

CA Veterans Aging Cohort Study TI HIV infection and the risk of diabetes mellitus SO AIDS LA English DT Article DE antiretroviral therapy; diabetes; HCV; HIV; risk ID CHRONIC HEPATITIS-C; MULTICENTER AIDS COHORT; INSULIN-RESISTANCE; VIRUS-INFECTION; ANTIRETROVIRAL THERAPY; POST-HAART; VETERANS; PREVALENCE; HEALTH; HCV AB Background: The influence of HIV infection on the risk of diabetes is unclear. We determined the association and predictors of prevalent diabetes mellitus in HIV infected and uninfected veterans. Methods: We determined baseline prevalence and risk factors for diabetes between HIV infected and uninfected veterans in the Veterans Aging Cohort Study. Logistic regression was used to determine the odds of diabetes in HIV infected and uninfected persons. Results: We studied 3227 HIV-infected and 3240 HIV-uninfected individuals. HIV-infected individuals were younger, more likely to be black males, have HCV coinfection and a lower BMI. HIV-infected individuals had a lower prevalence of diabetes at baseline (14.9 vs. 21.4%, P < 0.0001). After adjustment for known risk factors, HIV-infected individuals had a lower risk of diabetes (odds ratio = 0.84, 95% confidence interval = 0.72-0.97). Increasing age, male sex, minority race, and BMI were associated with an increased risk. The odds ratio for diabetes associated with increasing age, minority race and BMI were greater among HIV-infected veterans. HCV coinfection and nucleoside and nonnucleoside reverse transcriptase inhibitor therapy were associated with a higher risk of diabetes in HIV-infected veterans. Conclusion: Although HIV infection itself is not associated with increased risk of diabetes, increasing age; HCV coinfection and BMI have a more profound effect upon the risk of diabetes among HIV-infected persons. Further, long-term ARV treatment also increases risk. Future studies will need to determine whether incidence of diabetes mellitus differs by HIV status.

Txnip has therefore become an attractive target for diabetes therapy, but although we have found that txnip transcription is highly induced by glucose through a unique carbohydrate response element, the factors controlling this effect have remained unknown. Using transient transfection experiments, we now show that overexpression of the carbohydrate response element-binding protein (ChREBP) transactivates the txnip promoter, whereas ChREBP knockdown by small interfering RNA completely blunts glucose-induced txnip transcription. Moreover, chromatin immunoprecipitation demonstrated that glucose leads to a dose- and time-dependent recruitment of ChREBP to the txnip promoter in vivo in INS-1 beta cells as well as human islets. Furthermore, we found that the co-activator and histone acetyltransferase p300 co-immunoprecipitates with ChREBP and also binds to the txnip promoter in response to glucose. Interestingly, this is associated with specific acetylation of histone H4 and recruitment of RNA polymerase II as measured by chromatin immunoprecipitation. Thus, with this study we have identified ChREBP as the transcription factor that mediates glucose-induced txnip expression in human islets and INS-1 beta cells and have characterized the chromatin modification associated with glucose-induced txnip transcription. In addition, the results reveal for the first time that ChREBP interacts with p300. This may explain how ChREBP induces H4 acetylation and sheds new light on glucose-mediated regulation of chromatin structure and transcription.

TI A tissue-scale gradient of hydrogen peroxide mediates rapid wound detection in zebrafish SO NATURE LA English DT Article ID TUMOR-SUPPRESSOR PTEN; ENDOTHELIAL-CELLS; NOX INHIBITOR; DUAL OXIDASES; INFLAMMATION; CHEMOTAXIS; MIGRATION; GROWTH; NEUTROPHILS; EXPRESSION AB Barrier structures (for example, epithelia around tissues and plasma membranes around cells) are required for internal homeostasis and protection from pathogens. Wound detection and healing represent a dormant morphogenetic program that can be rapidly executed to restore barrier integrity and tissue homeostasis. In animals, initial steps include recruitment of leukocytes to the site of injury across distances of hundreds of micrometres within minutes of wounding. The spatial signals that direct this immediate tissue response are unknown. Owing to their fast diffusion and versatile biological activities, reactive oxygen species, including hydrogen peroxide (H2O2), are interesting candidates for wound-to-leukocyte signalling. Here we probe the role of H2O2 during the early events of wound responses in zebrafish larvae expressing a genetically encoded H2O2 sensor(1). This reporter revealed a sustained rise in H2O2 concentration at the wound margin, starting similar to 3 min after wounding and peaking at similar to 20 min, which extended similar to 100-200 mu m into the tail-fin epithelium as a decreasing concentration gradient. Using pharmacological and genetic inhibition, we show that this gradient is created by dual oxidase (Duox), and that it is required for rapid recruitment of leukocytes to the wound. This is the first observation, to our knowledge, of a tissue-scale H2O2 pattern, and the first evidence that H2O2 signals to leukocytes in tissues, in addition to its known antiseptic role.

This protein is known to catalyze both hydrolysis at high water contents and transesterification in quasi-anhydrous conditions. Here, we investigated the Thermomyces lanuginosa lipase structure in solution in the presence of a tributyrin aggregate using 30 ns molecular-dynamics simulations. The water content of the active-site groove was modified between the runs to focus on the protein-water molecule interactions and their implications for protein structure and protein-lipid interactions. The simulations confirmed the high plasticity of the lid fragment and showed that lipid molecules also bind to a secondary pocket beside the lid. Together, these results strongly suggest that the lid plays a role in the anchoring of the protein to the aggregate. The simulations also revealed the existence of a polar channel that connects the active-site groove to the outside solvent. At the inner extremity of this channel, a tyrosine makes hydrogen bonds with residues interacting with the catalytic triad. This system could function as a pipe (polar channel) controlled by a valve (the tyrosine) that could regulate the water content of the active site. C1 [Santini, S.; Crowet, J.

However, improvements are modest, and are associated with myopathy and immunosuppression so that alternative treatments are needed. Oxandrolone is an androgenic steroid with potential neuroprotective properties that is used to prevent muscle loss and is not immunosuppressive. Oxandrolone increased locomotor recovery concomitant with reduced loss of cord tissue in a standard weight drop model of spinal cord contusion injury indicating oxandrolone as a possible alternative to methylprednisolone. Oxandrolone also increased axonal sprouting within the ventral horns distal to the injury consistent with formation of relay circuits mediating locomotor recovery.

We examined the impact of coexisting conditions on the quality of care for hypertension and patient perception of overall quality of their health care. Methods and Results-We classified 141 609 veterans with hypertension into 4 condition groups: those with hypertension-concordant ( diabetes mellitus, ischemic heart disease, dyslipidemia) and/or -discordant ( arthritis, depression, chronic obstructive pulmonary disease) conditions or neither. We measured blood pressure control at the index visit, overall good quality of care for hypertension, including a follow-up interval, and patient ratings of satisfaction with their care. Associations between condition type and number of coexisting conditions on receipt of overall good quality of care were assessed with logistic regression. The relationship between patient assessment and objective measures of quality was assessed. Of the cohort, 49.5% had concordant-only comorbidities, 8.7% had discordant-only comorbidities, 25.9% had both, and 16.0% had none. Odds of receiving overall good quality after adjustment for age were higher for those with concordant comorbidities ( odds ratio, 1.78; 95% confidence interval, 1.70 to 1.87), discordant comorbidities ( odds ratio, 1.32; 95% confidence interval, 1.23 to 1.41), or both ( odds ratio, 2.25; 95% confidence interval, 2.13 to 2.38) compared with neither. Findings did not change after adjustment for illness severity and/or number of primary care and specialty care visits. Patient assessment of quality did not vary by the presence of coexisting conditions and was not related to objective ratings of quality of care. Conclusions-Contrary to expectations, patients with greater complexity had higher odds of receiving high-quality care for hypertension. Subjective ratings of care did not vary with the presence or absence of comorbid conditions. Our findings should be reassuring to those who care for the most medically complex patients and are concerned that they will be penalized by performance measures or patient ratings of their care.

Medication nonadherence is a growing concern to clinicians, healthcare systems, and other stakeholders (eg, payers) because of mounting evidence that it is prevalent and associated with adverse outcomes and higher costs of care. To date, measurement of patient medication adherence and use of interventions to improve adherence are rare in routine clinical practice. The goals of the present report are to address (1) different methods of measuring adherence, (2) the prevalence of medication nonadherence, (3) the association between nonadherence and outcomes, (4) the reasons for nonadherence, and finally, (5) interventions to improve medication adherence.

Assessing pancreatic cancer care by using quality indicators could help reduce this variability. However, valid quality indicators are not currently available for pancreatic cancer management, and a composite assessment of the quality of pancreatic cancer care in the United States has not been done. Potential quality indicators were identified from the literature, consensus guidelines, and interviews with experts. A panel of 20 pancreatic cancer experts ranked potential quality indicators for validity based on the RAND/UCLA Appropriateness Methodology. The rankings were rated as valid (high or moderate validity) or not valid. Adherence with valid indicators at both the patient and the hospital levels and a composite measure of adherence at the hospital level were assessed using data from the National Cancer Data Base (2004-2005) for 49 065 patients treated at 1134 hospitals. Summary statistics were calculated for each individual candidate quality indicator to assess the median ranking and distribution. Of the 50 potential quality indicators identified, 43 were rated as valid (29 as high and 14 as moderate validity). Of the 43 valid indicators, 11 (25.6%) assessed structural factors, 19 (44.2%) assessed clinical processes of care, four (9.3%) assessed treatment appropriateness, four (9.3%) assessed efficiency, and five (11.6%) assessed outcomes. Patient-level adherence with individual indicators ranged from 49.6% to 97.2%, whereas hospital-level adherence with individual indicators ranged from 6.8% to 99.9%. Of the 10 component indicators (contributing 1 point each) that were used to develop the composite score, most hospitals were adherent with fewer than half of the indicators (median score = 4; interquartile range = 3-5). Based on the quality indicators developed in this study, there is considerable variability in the quality of pancreatic cancer care in the United States. Hospitals can use these indicators to evaluate the pancreatic cancer care they provide and to identify potential quality improvement opportunities.

We sought to assess health-related quality-of-life outcomes for patients 48 months after treatment for localized prostate cancer. Men treated for localized prostate cancer (N = 475) were evaluated before treatment and at 11 intervals during the 48 months after intervention. Changes in mean health-related quality-of-life scores and the probability of regaining baseline levels of health-related quality of life were compared between treatment groups. All statistical tests were two-sided. Urinary incontinence was more common after prostatectomy (n = 307) than after brachytherapy (n = 90) or external beam radiation therapy (n = 78) (both P < .001), whereas voiding and storage urinary symptoms were more prevalent after brachytherapy than after prostatectomy (both P <.001). Sexual dysfunction profoundly affected all three treatment groups, with a lower likelihood of regaining baseline function after prostatectomy than after external beam radiation therapy or brachytherapy (P <.001). Bowel dysfunction was more common after either form of radiation therapy than after prostatectomy. These results may guide decision making for treatment selection and clinical management of patients with health-related quality-of-life impairments after treatment for localized prostate cancer.

Methods: Retrospective chart review of children with MS treated with cyclophosphamide. Demographic, clinical, treatment, and MRI parameters were collected. Results: We identified 17 children with MS treated with cyclophosphamide. All but one had worsening of Expanded Disability Status Scale scores or multiple relapses prior to treatment initiation. Children were treated with one of three regimens: 1) induction therapy alone; 2) induction therapy with pulse maintenance therapy; or 3) pulse maintenance therapy alone. Treatment resulted in a reduction in relapse rate and stabilization of disability scores assessed 1 year after treatment initiation in the majority of patients. Longer follow-up was available for most cases. Cyclophosphamide was well tolerated in most patients. However, side effects included vomiting, transient alopecia, osteoporosis, and amenorrhea. One patient developed bladder carcinoma that was successfully treated. Conclusions: Cyclophosphamide is an option for the treatment of children with aggressive multiple sclerosis refractory to first-line therapies. Recommendations regarding patient selection, treatment administration, and monitoring are discussed. Neurology (R) 2009;72:2076-2082 C1 [Makhani, N.; Branson, H. M.; Banwell, B.

We tested whether simple geometric models generated accurate estimates of these volumes. Methods: Acute diffusion-weighted image (DWI) and perfusion (mean transit time [MTT]) in 63 strokes and established infarct volumes in 50 subacute strokes were measured by computerized planimetry. Mismatch was defined as MTT/DWI >= 1.2. Observers, blinded to planimetric values, measured lesions in three perpendicular axes A, B, and C. Geometric estimates of sphere, ellipsoid, bicone, and cylinder were compared to planimetric volume by least-squares linear regression. Results: The ABC/2 formula (ellipsoid) was superior to other geometries for estimating volume of DWI (slope 1.16, 95% confidence interval [CI] 0.94 to 1.38; R(2) = 0.91, p = 0.001) and MTT (slope 1.11, 95% CI 0.99 to 1.23; R(2) = 0.89, p = 0.001). The intrarater and interrater reliability for ABC/2 was high for both DWI (0.992 and 0.965) and MTT (0.881 and 0.712). For subacute infarct, the ABC/2 formula also best estimated planimetric volume (slope 1.00, 95% CI 0.98 to 1.19; R(2) = 0.74, p = 0.001). In general, sphere and cylinder geometries overestimated all volumes and bicone underestimated all volumes. The positive predictive value for mismatch was 92% and negative predictive value was 33%. Conclusions: Of the models tested, ABC/2 is reproducible, is accurate, and provides the best simple geometric estimate of infarction and mean transit time volumes. ABC/2 has a high positive predictive value for identifying mismatch greater than 20% and might be a useful tool for rapid determination of acute stroke treatment.

CA Alzheimer's Dis Cooperative Study TI Donepezil delays progression to AD in MCI subjects with depressive symptoms SO NEUROLOGY LA English DT Article ID MILD COGNITIVE IMPAIRMENT; ALZHEIMERS-DISEASE; NEUROPSYCHIATRIC SYMPTOMS; FOLLOW-UP; DEVELOPING DEMENTIA; CONVERSION; APATHY; GALANTAMINE; HYPOTHESIS; PREDICTION AB Objective: To determine whether the presence of depression predicts higher rate of progression to Alzheimer disease (AD) in patients with amnestic mild cognitive impairment (aMCI) and whether donepezil treatment beneficially affect this relationship. Methods: The study sample was composed of 756 participants with aMCI from the 3-year, double-blind, placebo-controlled Alzheimer's Disease Cooperative Study drug trial of donepezil and vitamin E. Beck Depression Inventory (BDI) was used to assess depressive symptoms at baseline and participants were followed either to the end of study or to the primary endpoint of progression to probable or possible AD. Results: Cox proportional hazards regression, adjusted for age at baseline, gender, apolipoprotein genotype, and NYU paragraph delayed recall score, showed that higher BDI scores were associated with progression to AD (p = 0.03). The sample was stratified into depressed (BDI score >= 10; n = 208) and nondepressed (BDI < 10; n = 548) groups. Kaplan-Meier analysis showed that among the depressed subjects, the proportion progressing to AD was lower for the donepezil group than the combined vitamin E and placebo groups at 1.7 years (p = 0.023), at 2.2 years (p = 0.025), and remained marginally lower at 2.7 years (p = 0.070). The survival curves among the three treatment groups did not differ within the nondepressed participants. Conclusions: Results suggest that depression is predictive of progression from amnestic mild cognitive impairment (aMCI) to Alzheimer disease (AD) and treatment with donepezil delayed progression to AD among depressed subjects with aMCI. Donepezil appears to modulate the increased risk of AD conferred by the presence of depressive symptoms. Neurology (R) 2009;72:2115-2121 C1 [Lu, P. H.; Teng, E.; Tingus, K.; Cummings, J.

We have shown that the NF2 tumor suppressor Merlin inhibits EGFR internalization and signaling in a cell contact-dependent manner. Interestingly, despite the paucity of recurring mutations in human renal cell carcinoma (RCC), homozygous mutation of the NF2 gene is found in approximate to 2% of RCC patient samples in the Sanger COSMIC database. To examine the roles of Merlin and EGFR in kidney tumorigenesis, we generated mice with a targeted deletion of Nf2 in the proximal convoluted epithelium using a Villin-Cre transgene. All of these mice developed intratubular neoplasia by 3 months, which progressed to invasive carcinoma by 6-10 months. Kidneys from these mice demonstrated marked hyperproliferation and a concomitant increase in label-retaining putative progenitor cells. Early lumen-filling lesions in this model exhibited hyperactivation of EGFR signaling, altered solubility of adherens junctions components, and loss of epithelial polarity. Renal cortical epithelial cells derived from either early or late lesions were dependent on EGF for in vitro proliferation and were arrested by pharmacologic inhibition of EGFR or re-expression of Nf2. These cells formed malignant tumors upon s.c. injection into immunocompromised mice before in vitro passage. Treatment of Vil-Cre;Nf2(lox/lox) mice with the EGFR inhibitor erlotinib halted the proliferation of tumor cells. These studies give added credence to the role of EGFR signaling and perhaps Nf2 deficiency in RCC and describe a rare and valuable mouse model for exploring the molecular basis of this disease.

To assess the long-term clinical safety of dose-titrated lansoprazole as maintenance therapy for up to 82 months in subjects with healed erosive oesophagitis. Clinical safety was assessed by monitoring adverse events (AEs), laboratory data including serum gastrin levels, and endoscopy. Mean duration (+/- s.d.) of lansoprazole treatment during the titrated open-label period was 56 +/- 24 months (range < 1-82 months). Overall, 189 of 195 (97%) subjects experienced a total of 2825 treatment-emergent AEs. Most AEs occurred during the first year of treatment, were mild-to-moderate in severity and resolved while on treatment. Of 155 serious AEs (in 74 subjects), only two (colitis and rectal haemorrhage in one subject) were considered treatment-related. Sixty-nine of 195 subjects (35%) experienced 187 treatment-related AEs, with diarrhoea (10%), headache (8%) and abdominal pain (6%) being the most common. Gastrin levels >= 400 pg/mL were seen in 9% of subjects; hypergastrinemia was not associated with gastro-intestinal AEs or nodules/polyps. Lansoprazole maintenance therapy for up to 6 years is safe and well tolerated in subjects with healed erosive oesophagitis.

TI Eligibility of Individuals With Subclinical Coronary Artery Calcium and Intermediate Coronary Heart Disease Risk for Reclassification (from the Framingham Heart Study) SO AMERICAN JOURNAL OF CARDIOLOGY LA English DT Article ID ELECTRON-BEAM TOMOGRAPHY; C-REACTIVE PROTEIN; COMPUTED-TOMOGRAPHY; EVENTS; PREDICTION; COHORT; ADULTS; AGE; REPRODUCIBILITY; QUANTIFICATION AB Coronary artery calcium (CAC) predicts risk for coronary heart disease (CRD) events and perhaps CAC testing may further stratify risk in individuals at intermediate CHD risk. We sought to determine the percentage of participants at intermediate CHD risk who could potentially be reclassified as having a high CHD risk based on the presence of a high CAC score and the prevalence, treatment, and control of CHD risk factors in this group. Framingham Heart Study Offspring and Third Generation cohort participants underwent multidetector computed tomography (n = 3,529, mean age 51 years, 48% women). High CAC was defined as >= 90th age- and gender-specific percentiles based on a healthy reference group or by an absolute modified Agatston score of 100 HU. Prevalence of CHD risk factors (hypertension, hypercholesterolemia, high low-density lipoprotein cholesterol, low high-density lipoprotein cholesterol, smoking, and obesity), their treatment, and control was compared between nondiabetic participants with and without high CAC. Of the 595 participants at intermediate CHD risk, 22% had CAC 90th percentile and 39% had CAC 100 and could be eligible for reclassification as having a high CHD risk based on the presence of a high CAC score. There were no statistically significant differences in prevalence, treatment, and control of risk factors between those with and without high CAC. In conclusion, prevalence of CHD risk factors did not differ between intermediate-risk participants with and without high CAC. Approximately 25% of intermediate-risk individuals have high CAC scores and may be eligible for reclassification into a higher-risk category. (C) 2009 Published by Elsevier Inc.

Kent CA Osteoarthritis Initiative Inves TI The Knee Pain Map: Reliability of a Method to Identify Knee Pain Location and Pattern SO ARTHRITIS & RHEUMATISM-ARTHRITIS CARE & RESEARCH LA English DT Article ID BONE-MARROW; OSTEOARTHRITIS; ASSOCIATION AB Objective. To describe the location and pattern of knee pain in patients with chronic, frequent knee pain using the Knee Pain Map, and to evaluate the inter- and intrarater reliability of the map. Methods. A cohort of 799 participants from the University of Pittsburgh Osteoarthritis Initiative Clinical Center who had knee pain in the last 12 months were studied. Trained interviewers assessed and recorded participant-reported knee pain patterns into 8 local areas, 4 regional areas, or as diffuse. Inter- and intrarater reliability were assessed using Fleiss' kappa. Results. Participants most often reported localized (69%) followed by regional (14%) or diffuse (10%) knee pain. In those with localized pain, the most commonly reported locations were the medial (56%) and lateral (43%) joint lines. In those with regional pain, the most commonly reported regions were the patella (44%) and medial region (38%). There was. excellent interrater reliability for the identification of localized and regional pain patterns (kappa = 0.7-0.9 and 0.7-0.8, respectively). The interrater reliability for specific locations was also excellent (kappa = 0.7-1.0) when the number of participants with pain in a location was >4. For regional pain, the kappa for specific regions varied from 0.7-1.0. Conclusion. The majority of participants could identify the location of their knee pain, and trained interviewers could reliably record those locations. The variation in locations suggests that there are multiple sources of pain in knee OA. Additional studies are needed to determine whether specific knee pain patterns correlate with discrete pathologic findings on radiographs or magnetic resonance images.

No differences were present at rest or in HRV during IGHT. HRC was significantly lower in the CG compared to controls at 48 h during IHGT. In CG at Week Two during IHGT, HRC was significantly greater than 48 h observations and not significantly different than controls. The findings suggest that HRC may have utility in detecting efferent cardiac autonomic anomalies within two weeks of concussion. Published by Elsevier B.V.

Recognition of facial emotion depends on processing affective and nonaffective facial signals, as well as basic visual attributes. We examined whether and how poor facial emotion recognition in schizophrenia is related to basic visual processing and nonaffective face recognition. Methods: Schizophrenia patients (n = 32) and healthy control subjects (n = 29) performed emotion discrimination, identity discrimination, and visual contrast detection tasks, where the emotionality, distinctiveness of identity, or visual contrast was systematically manipulated. Subjects determined which of two presentations in a trial contained the target: the emotional face for emotion discrimination, a specific individual for identity discrimination, and a sinusoidal grating for contrast detection. Results: Patients had significantly higher thresholds (worse performance) than control subjects for discriminating both fearful and happy faces. Furthermore, patients' poor performance in fear discrimination was predicted by performance in visual detection and face identity discrimination. Conclusions: Schizophrenia patients require greater emotional signal strength to discriminate fearful or happy face images from neutral ones. Deficient emotion recognition in schizophrenia does not appear to be determined solely by affective processing but is also linked to the processing of basic visual and facial information.

The authors report the safety and efficacy of such regimens in elderly patients using a large phase III trial (bolus, infusional, or capecitabine with camptostar-celecoxib [BICC-C]) cohort. METHODS: In period 1, 430 previously untreated patients with mCRC were randomized in a 3-by-2 design to receive irinotecan plus infusional 5-fluorouracil, and leucovorin (FOLFIRI), irinotecan plus bolus 5-fluorouracil/leucovorin (mIFL), and irinotecan plus oral capecitabine (CapeIRI). In period 2, an additional 117 patients were randomized to receive FOLFIRI or mIFL and bevacizumab. In both periods patients were also randomized to a double-blind treatment with celecoxib or placebo. A secondary analysis was conducted examining the safety and efficacy of these regimens in elderly (age >70 years) versus nonelderly (age <= 70 years) patients. RESULTS: In period 1, 19.5% of patients were elderly, compared with 24.8% in period 2. Rates of grade 3 and higher toxicity did not differ significantly between age groups in either period by treatment arm, with the exception of asthenia in the FOLFIRI and CapeIRI arms (P=.05 and P=.03, respectively) and dehydration in the CapeIRI arm in period I (P=.02). Overall progression-free survival for FOLFIRI in both periods was not statistically different by age. Objective responses and overall survival did not differ by patient age within treatment arms and periods. CONCLUSIONS: Irinotecan/fluoropyrimidine combinations are well tolerated in the elderly population, with similar efficacy to that found in nonelderly patients in first-line mCRC.

TI Factors Influencing Changes in Employment Among Women With Newly Diagnosed Breast Cancer SO CANCER LA English DT Article DE breast cancer; employment; disability; outcomes; risk factors ID QUALITY-OF-LIFE; COMORBIDITY INDEX; CLAIMS DATA; LONG-TERM; SURVIVORS; WORK; CHEMOTHERAPY; HEALTH; COHORT; RETURN AB BACKGROUND: Although studies have demonstrated that women are less likely to work after they are diagnosed with breast cancer, the influence of cancer treatments on employment is less clear. The authors of this report assessed whether chemotherapy or radiation therapy was associated with a disruption in employment during the year after a breast cancer diagnosis. METHODS: Using a database of health insurance claims that covered 5.6 million US residents, 3233 women aged <= 63 years were identified who were working full time or part time when they were diagnosed with breast cancer between 1998 and 2002. All changes in employment during the year after a breast cancer diagnosis were identified. Using a Cox proportional hazards model that incorporated time-varying treatment variables, the authors evaluated the impact of chemotherapy and radiation therapy on the likelihood of experiencing an employment disruption. RESULTS: Although most women (93%) continued to work, chemotherapy recipients were more likely than nonrecipients to go on long-term disability, stop working, or retire (hazards ratio, 1.8; P<.01). Women aged :54 years were more likely to experience a change in employment than women aged <= 44 years (P<.01). Radiation therapy did not influence employment (P=.22). CONCLUSIONS: in this population of employed, insured women, chemotherapy had a negative impact on employment. This finding may aid treatment decision making and could foster the development of interventions that support a patient's ability to continue working after treatment. It also reinforces the need to assess the impact of treatments, especially new treatments, on patient-centered outcomes such as employment. Cancer 2009;115:2775-82. (C) 2009 American Cancer Society.

Here, we report high constitutive hypoxia-inducible factor-1 alpha (Hif-1 alpha) expression in MM cells, which is associated with oncogenic c-Myc. A drug screen for anti-MM agents that decrease Hif-1 alpha and c-Myc levels identified a variety of compounds, including bortezomib, lenalidomide, enzastaurin, and adaphostin. Functionally, based on transient knockdowns and overexpression, our data delineate a c-Myc/Hif-1 alpha-dependent pathway mediating vascular endothelial growth factor production and secretion. The antiangiogenic activity of our tool compound, adaphostin, was subsequently shown in a zebrafish model and translated into a preclinical in vitro and in vivo model of MM in the bone marrow milieu. Our data, therefore, identify Hif-1 alpha as a novel molecular target in MM and add another facet to anti-MM drug activity.

However, there are no effective agents that directly inhibit MUC1 and induce death of breast cancer cells. We have synthesized a MUC1 inhibitor (called GO-201) that binds to the MUC1 cytoplasmic domain and blocks the formation of MUC1 oligomers in cells. GO-201, and not an altered version, attenuates targeting of MUC1 to the nucleus of human breast cancer cells, disrupts redox balance, and activates the DNA damage response. GO-201 also arrests growth and induces necrotic death. By contrast, the MUC1 inhibitor has no effect on cells null for MUC1 expression or nonmalignant mammary epithelial cells. Administration of GO-201 to nude mice bearing human breast tumor xenografts was associated with loss of tumorigenicity and extensive necrosis, which results in prolonged regression of tumor growth. These findings show that targeting the MUC1 oncoprotein is effective in inducing death of human breast cancer cells in vitro and in tumor models.

TI Mechanism of Regulation and Suppression of Melanoma Invasiveness by Novel Retinoic Acid Receptor-gamma Target Gene Carbohydrate Sulfotransferase 10 SO CANCER RESEARCH LA English DT Article ID DEPENDENT SIGNALING PATHWAY; CELL-ADHESION MOLECULE; RAR-ALPHA; TRANSCRIPTIONAL ACTIVATION; NEUROBLASTOMA-CELLS; RNA ACTIVATOR; MUTANT MICE; F9 CELLS; BETA 2; EXPRESSION AB Retinoic acid (RA) induces growth arrest and differentiation of S91 murine melanoma cells and serves as a valuable model for this disease. RA acts through activation of RA receptors (RAR), which are members of the nuclear receptor superfamily of ligand-inducible transcription factors. Interestingly, differentiation is mediated by RAR gamma, but not by RAR alpha or RAR beta, suggesting that RAR gamma possesses unique and uncharacterized molecular properties. To address this question, DNA microarrays in combination with RAR isoform-specific agonists were employed to identify novel RAR gamma target genes that may play a role in this process. Here, we identified and validated carbohydrate sulfotransferase 10 (CHST10) as a novel RAR gamma target gene in S91 cells. The RAR gamma-inducible CHST10 promoter was obtained, and two atypical, independently functioning RA response elements were identified in a 425 bp region. Surprisingly, this fragment is bound by RAR gamma, but not by RAR alpha or RAR beta, thus providing a mechanism for the observed RAR gamma-specific regulation. CHST10 is a sulfotransferase that forms HNK-1 glycan on neural cell adhesion proteins and glycolipids, and HNK-1 is thought to modulate cell adhesion and possibly metastasis. We show that CHST10 is also regulated by RAR gamma in a significant subset of human melanoma cells, and three-dimensional cell culture migration assays suggest that CHST10 functions as a suppressor of invasiveness, but not proliferation, in these cells. Induction of CHST10 by RAR gamma-activating retinoids may present a novel therapeutic strategy to inhibit invasiveness in a subset of melanoma patients.

To understand the biological processes and signaling mechanisms underlying the formation of such reactive stroma, we carried out microarray gene expression analysis of laser-captured reactive stroma and matched normal stroma. Experimental Design: Seventeen cases of reactive stroma grade 3 cancer were used to laser-capture tumor and normal stroma. Expression analysis was carried out using Agilent 44K arrays. Up-regulation of selected genes was confirmed by quantitative reverse transcription-PCR. Expression data was analyzed to identify significantly up- and down-regulated genes, and gene ontology analysis was used to define pathways altered in reactive stroma. Results: A total of 544 unique genes were significantly higher in the reactive stroma and 606 unique genes were lower. Gene ontology analysis revealed significant alterations in a number of novel processes in prostate cancer reactive stroma, including neurogenesis, axonogenesis, and the DNA damage/repair pathways, as well as evidence of increases in stem cells in prostate cancer reactive stroma. Conclusions: Formation of reactive stroma in prostate cancer is a dynamic process characterized by significant alterations in growth factor and signal transduction pathways and formation of new structures, including nerves and axons.

TI The Monoclonal Antibody nBT062 Conjugated to Cytotoxic Maytansinoids Has Selective Cytotoxicity Against CD138-Positive Multiple Myeloma Cells In vitro and In vivo SO CLINICAL CANCER RESEARCH LA English DT Article ID DRUG-RESISTANCE; BONE-MARROW; GEMTUZUMAB OZOGAMICIN; ANTITUMOR-ACTIVITY; CANCER-CELLS; GROWTH; SYNDECAN-1; APOPTOSIS; THERAPY; DIFFERENTIATION AB Purpose: We investigated the antitumor effect of murine/human chimeric CD138-specific monoclonal antibody nBT062 conjugated with highly cytotoxic maytansinoid derivatives against multiple myeloma (MM) cells in vitro and in vivo. Experimental Design: We examined the growth inhibitory effect of BT062-SPDB-DM4, BT062-SMCC-DM1, and BT062-SPP-DM1 against MM cell lines and primary tumor cells from MM patients. We also examined in vivo activity of these agents in murine MM cell xenograft model of human and severe combined immunodeficient (SCID) mice bearing implant bone chips injected with human MM cells (SCID-hu model). Results: Anti-CD138 immunoconjugates significantly inhibited growth of MM cell lines and primary tumor cells from MM patients without cytotoxicity against peripheral blood mononuclear cells from healthy volunteers. In MM cells, they induced G(2)-M cell cycle arrest, followed by apoptosis associated with cleavage of caspase-3, caspase-8, caspase-9, and poly(ADP-ribose) polymerase. Nonconjugated nBT062 completely blocked cytotoxicity induced by nBT062-maytansinoid conjugate, confirming that specific binding is required for inducing cytotoxicity. Moreover, nBT062-maytansinoid conjugates blocked adhesion of MM cells to bone marrow stromal cells. The coculture of MM cells with bone marrow stromal cells protects against dexamethasone-induced death but had no effect on the cytotoxicity of immunoconjugates. Importantly, nBT062-SPDB-DM4 and nBT062-SPP-DM1 significantly inhibited MM tumor growth in vivo and prolonged host survival in both the xenograft mouse models of human MM and SCID-hu mouse model. Conclusion: These results provide the preclinical framework supporting evaluation of nBT062-maytansinoid derivatives in clinical trials to improve patient outcome in MM.

CA Caspofungin High-Dose Study Grp TI A Multicenter, Double-Blind Trial of a High-Dose Caspofungin Treatment Regimen versus a Standard Caspofungin Treatment Regimen for Adult Patients with Invasive Candidiasis SO CLINICAL INFECTIOUS DISEASES LA English DT Article ID HIGH DRUG CONCENTRATIONS; AMPHOTERICIN-B; FUNGAL-INFECTIONS; RISK-FACTORS; CANDIDEMIA; FLUCONAZOLE; EPIDEMIOLOGY; CANDIDAEMIA; MICAFUNGIN; MORTALITY AB Background. The standard caspofungin treatment regimen (50 mg/day after a 70-mg dose on day 1) is effective and well tolerated for the treatment of invasive candidiasis, but experience with higher doses of caspofungin is limited. We evaluated the safety and efficacy of caspofungin at 3 times the standard dosing regimen. Methods. Patients with proven invasive candidiasis were randomized to receive a standard or high-dose (150 mg/day) caspofungin treatment regimen. Safety was assessed in all patients as treated. Efficacy was assessed as a secondary objective in a full-analysis-set population. A favorable overall response was defined as symptom resolution and microbiological clearance at the end of caspofungin therapy. Results. A total of 204 patients were included in the safety analysis (104 received the standard regimen, and 100 received the high-dose regimen), and 197 were included in the efficacy analysis (102 and 95 in the standard and high-dose treatment groups, respectively). Patient demographic characteristics, neutropenia status (6.7% and 8.0% had neutropenia, respectively), and Acute Physiology and Chronic Health Evaluation II scores (mean, 16.5 and 17, respectively) were similar between treatment groups. Significant drug-related adverse events occurred in 1.9% of patients receiving the standard regimen and 3.0% of patients receiving the high-dose regimen (difference, 1.1%; 95% confidence interval, -4.1% to 6.8%). The most-common drug-related adverse events in the standard and high-dose treatment groups were phlebitis (3.8% and 2.0%, respectively), increased alkaline phosphatase level (6.9% and 2.0%, respectively), and increased aspartate transaminase level (4.0% and 2.0%, respectively). Overall, 71.6% of patients who received the standard regimen and 77.9% of patients who received the high-dose regimen had favorable overall responses (difference, 6.3%; 95% confidence interval, -5.9% to 18.4%; not statistically significant). Mortality at 8 weeks after therapy was similar between groups. Conclusions. Both caspofungin dosing regimens were effective and well tolerated in patients with invasive candidiasis. No safety concerns were found for caspofungin at a dosage of 150 mg/day. C1 [Betts, Robert F.] Univ Rochester, Rochester, NY USA. [Gareca, Marcelo] Lehigh Valley Hosp, Allentown, PA USA.

Candidemia remains a major cause of morbidity and mortality in the health care setting, and the epidemiology of Candida infection is changing. Methods. Clinical data from patients with candidemia were extracted from the Prospective Antifungal Therapy (PATH) Alliance database, a comprehensive registry that collects information regarding invasive fungal infections. A total of 2019 patients, enrolled from 1 July 2004 through 5 March 2008, were identified. Data regarding the candidemia episode were analyzed, including the specific fungal species and patient survival at 12 weeks after diagnosis. Results. The incidence of candidemia caused by non-Candida albicans Candida species (54.4%) was higher than the incidence of candidemia caused by C. albicans (45.6%). The overall, crude 12-week mortality rate was 35.2%. Patients with Candida parapsilosis candidemia had the lowest mortality rate (23.7%; P < .001) and were less likely to be neutropenic (5.1%; P < .001) and to receive corticosteroids (33.5%; P < .001) or other immuno-suppressive drugs (7.9%; P = .002), compared with patients infected with other Candida species. Candida krusei candidemia was most commonly associated with prior use of antifungal agents (70.6%; P < .001), hematologic malignancy (52.9%; P < .001) or stem cell transplantation (17.7%; P < .001), neutropenia (45.1%; P < .001), and corticosteroid treatment (60.8%; P < .001). Patients with C. krusei candidemia had the highest crude 12-week mortality in this series (52.9%; P < .001). Fluconazole was the most commonly administered antimicrobial, followed by the echinocandins, and amphotericin B products were infrequently administered. Conclusions. The epidemiology and choice of therapy for candidemia are rapidly changing. Additional study is warranted to differentiate host factors and differences in virulence among Candida species and to determine the best therapeutic regimen.

TI Endothelial cells promote migration and proliferation of enteric neural crest cells via beta 1 integrin signaling SO DEVELOPMENTAL BIOLOGY LA English DT Article DE Enteric nervous system; Endothelial cells; Blood vessels; Hirschsprung's disease; Integrins; Avian; Zebrafish ID EXTRACELLULAR-MATRIX; MONOCLONAL-ANTIBODY; NERVOUS-SYSTEM; TRANSGENIC ZEBRAFISH; AGANGLIONIC BOWEL; AVIAN EMBRYO; LAMININ; FIBRONECTIN; RECEPTOR; NEURONS AB Enteric neural crest-derived cells (ENCCs) migrate along the intestine to form a highly organized network of ganglia that comprises the enteric nervous system (ENS). The signals driving the migration and patterning of these cells are largely unknown. Examining the spatiotemporal development of the intestinal neurovasculature in avian embryos, we find endothelial cells (ECs) present in the gut prior to the arrival of migrating ENCCs. These ECs are patterned in concentric rings that are predictive of the positioning of later arriving crest-derived cells, leading us to hypothesize that blood vessels may serve as a substrate to guide ENCC migration. Immunohistochemistry at multiple stages during ENS development reveals that ENCCs are positioned adjacent to vessels as they colonize the gut. A similar close anatomic relationship between vessels and enteric neurons was observed in zebrafish larvae. When EC development is inhibited in Cultured avian intestine, ENCC migration is arrested and distal aganglionosis results, suggesting that ENCCs require the presence of vessels to colonize the gut. Neural tube and avian midgut were explanted onto a variety of substrates, including components of the extracellular matrix and various cell types, such as fibroblasts, smooth muscle cells, and endothelial cells. We find that crest-derived cells from both the neural tube and the midgut migrate avidly onto Cultured endothelial cells. This EC-induced migration is inhibited by the presence of CSAT antibody, which blocks binding to beta 1 integrins expressed on the surface of crest-derived cells. These results demonstrate that ECs provide a Substrate for the migration of ENCCs via an interaction between beta 1 integrins on the ENCC surface and extracellular matrix proteins expressed by the intestinal vasculature. These interactions may play an important role in guiding migration and patterning in the developing ENS. (C) 2009 Elsevier Inc. All rights reserved.

TI Gene therapy for retinitis pigmentosa and Leber congenital amaurosis caused by defects in AIPL1: effective rescue of mouse models of partial and complete Aipl1 deficiency using AAV2/2 and AAV2/8 vectors SO HUMAN MOLECULAR GENETICS LA English DT Article ID RCS RAT MODEL; RETINAL DEGENERATION; PHOTORECEPTOR DEGENERATION; CGMP PHOSPHODIESTERASE; CHILDHOOD BLINDNESS; REPLACEMENT THERAPY; RESTORES VISION; CANINE MODEL; PROTEIN; MICE AB Defects in the photoreceptor-specific gene encoding aryl hydrocarbon receptor-interacting protein-like 1 (AIPL1) are clinically heterogeneous and present as Leber Congenital Amaurosis, the severest form of early-onset retinal dystrophy and milder forms of retinal dystrophies such as juvenile retinitis pigmentosa and dominant cone-rod dystrophy. [Perrault, I., Rozet, J.M., Gerber, S., Ghazi, I., Leowski, C., Ducroq, D., Souied, E., Dufier, J.L., Munnich, A. and Kaplan, J. (1999) Leber congenital amaurosis. Mol. Genet. Metab., 68, 200-208.] Although not yet fully elucidated, AIPL1 is likely to function as a specialized chaperone for rod phosphodiesterase (PDE). We evaluate whether AAV-mediated gene replacement therapy is able to improve photoreceptor function and survival in retinal degeneration associated with AIPL1 defects. We used two mouse models of AIPL1 deficiency simulating three different rates of photoreceptor degeneration. The Aipl1 hypomorphic (h/h) mouse has reduced Aipl1 levels and a relatively slow degeneration. Under light acceleration, the rate of degeneration in the Aipl1 h/h mouse is increased by 2-3-fold. The Aipl1-/- mouse has no functional Aipl1 and has a very rapid retinal degeneration. To treat the different rates of degeneration, two pseudotypes of recombinant adeno-associated virus (AAV) exhibiting different transduction kinetics are used for gene transfer. We demonstrate restoration of cellular function and preservation of photoreceptor cells and retinal function in Aipl1 h/h mice following gene replacement therapy using an AAV2/2 vector and in the light accelerated Aipl1 h/h model and Aipl1-/- mice using an AAV2/8 vector. We have thus established the potential of gene replacement therapy in varying rates of degeneration that reflect the clinical spectrum of disease. This is the first gene replacement study to report long-term rescue of a photoreceptor-specific defect and to demonstrate effective rescue of a rapid photoreceptor degeneration.

Despite the various treatment options for S. aureus infections, it remains a major hospital- and community-acquired opportunistic pathogen. With the emergence of multidrug-resistant S. aureus strains, there is an urgent need for the discovery of new antimicrobial drug targets in the organism. To this end, we reconstructed the metabolic networks of multidrug-resistant S. aureus strains using genome annotation, functional-pathway analysis, and comparative genomic approaches, followed by flux balance analysis-based in silico single and double gene deletion experiments. We identified 70 single enzymes and 54 pairs of enzymes whose corresponding metabolic reactions are predicted to be unconditionally essential for growth. Of these, 44 single enzymes and 10 enzyme pairs proved to be common to all 13 S. aureus strains, including many that had not been previously identified as being essential for growth by gene deletion experiments in S. aureus. We thus conclude that metabolic reconstruction and in silico analyses of multiple strains of the same bacterial species provide a novel approach for potential antibiotic target identification.

The control of Th1 cell trafficking into sites of infection and inflammation is an important determinant of Till cell function. We have previously shown that trafficking of adoptively transferred Ag-specific Th1 cells into the lung following airway Ag challenge depends on CXCR3 expression on Th1 cells and STAT1-inducible CXCR3 ligands in the lung. In this study, we show that LPS alters the mechanisms of Th1 cell recruitment. After a single intranasal dose of LPS, trafficking of adoptively transferred Ag-specific Th1 cell into the lung in response to airway Ag challenges was no longer dependent on CXCR3 and its ligands and instead was mediated through additional G alpha i-coupled chemoattractant receptor pathways, including CCR5. In addition, LPS markedly increased the magnitude of Ag-specific Th1 cell homing into the airways following airway Ag challenges. The increased trafficking of Ag-activated Th1 cells, in turn, dramatically amplified LPS-induced airway neutrophilic infiltration by maintaining high levels of the neutrophil active chemokines, KC and MIP-2, through an IFN-gamma dependent mechanism. Therefore, LPS increases Ag-specific Th1 cell trafficking into the airways and Ag-specific Th1 cells amplify the airway neutrophilic inflammatory response initiated by LPS. This reciprocal interaction between LPS and Ag-activated Th1 cells represents a collaborative connection between the innate and adaptive arms of the immune system.

TI Neutrophil-Derived IL-6 Limits Alveolar Barrier Disruption in Experimental Ventilator-Induced Lung Injury SO JOURNAL OF IMMUNOLOGY LA English DT Article ID RESPIRATORY-DISTRESS-SYNDROME; INTERLEUKIN-6-DEFICIENT MICE; INFLAMMATION; EXPRESSION; PROTECTION; MECHANISM; RESPONSES; BLOCKADE; IMMUNE AB IL-6 is a biological marker of ventilator-associated lung injury that may contribute to alveolar barrier dysfunction in acute respiratory distress syndrome. To determine whether IL-6 affects alveolar barrier disruption in a model of ventilator-induced lung injury, we examined alveolar barrier albumin flux in wild-type (WT) mice given an IL-6-blocking Ab (IL6AB) and mice deficient in IL-6 (LL6KO). Albumin flux was significantly higher in mice given IL6AB compared with mice given a control Ab. Unexpectedly, albumin flux was similar in WT and IL6KO mice. To examine the mechanisms for these findings, lung neutrophil accumulation (myeloperoxidase activity) was compared, revealing a correlation between lung neutrophil accumulation and albumin flux. IL6AB mice had significantly more lung neutrophils than WT and IL6KO mice, which were similar. Therefore, to determine whether the cellular source of IL-6 influences neutrophil accumulation and alveolar barrier function, chimeric mice were compared. WT/KO chimeras (WT mice with IL6KO hematopoietic cells) showed significantly greater albumin flux and neutrophil accumulation with mechanical ventilation than WT/WT mice. Neutrophil depletion decreased albumin flux in WT and WT/KO mice. IL6KO neutrophils were more adherent in an in vitro assay compared with WT neutrophils. IL-6 from a hematopoietic cell source limits alveolar barrier disruption potentially by reducing neutrophil contact with the endothelium. Modulation of IL-6 signaling in a cell type-specific fashion may be a therapeutic target for patients with acute lung injury. The Journal of Immunology, 2009, 182: 8056-8062.

TI Responsiveness of T Cells to Interleukin-7 Is Associated with Higher CD4(+) T Cell Counts in HIV-1-Positive Individuals with Highly Active Antiretroviral Therapy-Induced Viral Load Suppression SO JOURNAL OF INFECTIOUS DISEASES LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; SURFACE CCR5 DENSITY; IL-7 RECEPTOR-ALPHA; DISEASE PROGRESSION; SINGLE-CELL; IN-VIVO; HOMEOSTATIC PROLIFERATION; HIV-1-INFECTED PATIENTS; LYMPHOID HOMEOSTASIS; INFECTED PATIENTS AB Background. Despite suppression of the human immunodeficiency virus type 1 (HIV-1) load by highly active antiretroviral therapy (HAART), recovery of CD4(+) T cell counts can be impaired. We investigated whether this impairment may be associated with hyporesponsiveness of T cells to gamma-chain (gamma c) cytokines known to influence T cell homeostasis. Methods. The responsiveness of T cells to interleukin (IL)-2, IL-7, and IL-15 was determined by assessing cytokine-induced phosphorylation of the signal transducer and activator of transcription 5 (STAT5) in peripheral T cells obtained from 118 HIV-positive subjects and 13 HIV-negative subjects. Results. The responsiveness of T cells to interleukin (IL)-7 but not to IL-2 or IL-15 was lower among HIV-positive subjects than among HIV-negative subjects. Among subjects with viral load suppression, the degree of IL-7 responsiveness (1) correlated with naive CD4(+) T cell counts and was a better immune correlate of the prevailing CD4(+) T cell count than were levels of human leukocyte antigen-DR1 or programmed death-1, which are predictors of T cell homeostasis during HIV infection; and (2) was greater in subjects with complete (i.e., attainment of >= 500 CD4(+) T cells/mm(3) >= 5 years after initiation of HAART) versus incomplete immunologic responses. The correlation between plasma levels of IL-7 and CD4(+) T cell counts during HAART was maximal in subjects with increased IL-7 responsiveness. Conclusions. Responsiveness of T cells to IL-7 is associated with higher CD4(+) T cell counts during HAART and thus may be a determinant of the extent of immune reconstitution.

To understand the role of phosphorylation in Jak2 regulation, we used mass spectrometry to identify numerous Jak2 phosphorylation sites and characterize their significance for Jak2 function. Two sites outside of the tyrosine kinase domain, Tyr(317) in the FERM domain and Tyr(637) in the JH2 domain, exhibited strong regulation of Jak2 activity. Mutation of Tyr(317) promotes increased Jak2 activity, and the phosphorylation of Tyr(317) during cytokine signaling requires prior activation loop phosphorylation, which is consistent with a role for Tyr(317) in the feedback inhibition of Jak2 kinase activity after receptor stimulation. Comparison to several previously identified regulatory phosphorylation sites on Jak2 revealed a dominant role for Tyr(317) in the attenuation of Jak2 signaling. In contrast, mutation of Tyr(637) decreased Jak2 signaling and activity and partially suppressed the activating JH2 V617F mutation, suggesting a role for Tyr(637) phosphorylation in the release of JH2 domain-mediated suppression of Jak2 kinase activity during cytokine stimulation. The phosphorylation of Tyr(317) and Tyr(637) act in concert with other regulatory events to maintain appropriate control of Jak2 activity and cytokine signaling.

We demonstrate that the selective activation of a subset of the estrogen receptor alpha (ER alpha) cistrome in MCF7 breast cancer cells provides specificity to the estradiol (E2) response. ER alpha-specific enhancers that are subject to E2-induced coactivator-associated arginine methyltransferase 1 (CARM1) action are critical to E2-stimulated gene expression. This is true for both FoxA1-dependent and independent enhancers. In contrast, a subset of E2-suppressed genes are controlled by FoxA1-independent ER alpha binding sites. Nonetheless, these are sites of E2-induced CARM1 activity. In addition, the MCF7 RNA polymerase II cistrome reveals preferential occupancy of E2-regulated promoters prior to stimulation. Interestingly, E2-suppressed genes tend to lie in otherwise silent genomic regions. Together, our results suggest that the transcriptional response to E2 in breast cancer cells is dependent on the interplay between polymerase II pre-occupied promoters and the subset of the ER alpha cistrome associated with coactivation.

Results from studies in patients with anorexia nervosa (AN) showed an association between excessive physical activity (PA) and leptin. One recent report suggests a role for cortisol in PA. In this study, we assessed the relationships between PA and both, cortisol and leptin levels at the same time in patients with acute anorexia nervosa (acAN) in comparison to recovered patients (recAN). Methods: Plasma leptin, plasma cortisol, body mass index (BMI), and expert-ratings of qualities of PA were assessed in 36 acAN patients, 27 recAN patients and 44 healthy control woman (HCW). Regression analyses were used to predict PA using BMI, leptin and cortisol levels as predictor variables. Results: Leptin levels but not cortisol significantly contributed to the prediction of PA in acAN. In recAN PA was not elevated and not related to endocrine parameters but correlated positively with core eating disorder symptoms. Conclusions: Our work lends support to the proposed inverse association between peripheral leptin levels and excessive physical activity in AN. This relationship is specific to the state of semistarvation. The role of additional mediators remains to be clarified. (C) 2009 Elsevier Inc. All rights reserved.

As islet transplantation begins to show promise as a clinical method, there is a critical need for reliable, noninvasive techniques to monitor islet graft survival. Previous work in our laboratory has shown that human islets labeled with a superparamagnetic iron oxide contrast agent and transplanted into mice could be detected by magnetic resonance imaging (MRI). The potential translation of these findings to the clinical situation requires validation of our methodology in a non-human primate model, which we have now carried out in baboons (Papio hamadryas) and reported here. Research Design and Methods. For islet labeling, we adapted the Food and Drug Administration-approved superparamagnetic iron oxide contrast agent, Feridex, which is used clinically for liver imaging. After partial pancreatectomy, Feridex-labeled islets were prepared and autotransplanted underneath the renal capsule and into the liver. Longitudinal in vivo MRI at days 1, 3, 8, 16, 23, and 30 after transplantation was performed to track the islet grafts. Results. The renal subcapsular islet graft was easily detectable on T2*-weighted MR images as a pocket of signal loss disrupting the contour of the kidney at the transplantation site. Islets transplanted in the liver appeared as distinct signal voids dispersed throughout the liver parenchyma. A semiautomated computational analysis of our MRI data established the feasibility of monitoring both the renal and intrahepatic grafts during the studied posttransplantation period. Conclusion. This study establishes a method for the noninvasive, longitudinal detection of pancreatic islets transplanted into non-human primates using a low-field clinical MRI system.

METHODS: The MDCT scans of 164 patients with surgically verified pancreatic cystic lesions were reviewed by two readers to study the predictive value of various morphological features for establishing a diagnosis of SCAs. Accuracy in lesion characterization and reader confidence were correlated with lesion size (<= 3 cm or >= 3 cm) and scanning protocols (dedicated vs routine). RESULTS: 28/164 cysts (mean size, 39 mm; range, 8-92 mm) were diagnosed as SCA on pathology. The MDCT features predictive of diagnosis of SCA were microcystic appearance (22/28, 78.6%), surface lobulations (25/28, 89.3%) and central scar (9/28, 32.4%). Stepwise logistic regression analysis showed that only microcystic appearance was significant for CT diagnosis of SCA (P = 0.0001). The sensitivity, specificity and PPV of central scar and of combined microcystic appearance and lobulations were 32.4%/100%/100% and 68%/100%/100%, respectively. The reader confidence was higher for lesions > 3 cm (P = 0.02) and for MDCT scans performed using thin collimation (1.25-2.5 mm) compared to routine 5 mm collimation exams (P > 0.05). CONCLUSION: Central scar on MDCT is diagnostic of SCA but is seen in only one third of SCAs. Microcystic morphology is the most significant CT feature in diagnosis of SCA. A combination of microcystic appearance and surface lobulations offers accuracy comparable to central scar with higher sensitivity. (C) 2009 The WIG Press and Baishideng. All rights reserved.

Public health interventions are sought to lessen its prevalence or severity, and diet and nutrition have been identified as potential factors. With rapid changes in diet being one of the hallmarks of westernization, nutrition may play a key role in affecting the complex genetics and developmental pathophysiology of asthma. The present review investigates hypotheses about hygiene, antioxidants, lipids and other nutrients, food types and dietary patterns, breastfeeding, probiotics and intestinal microbiota, vitamin D, maternal diet, and genetics. Early hypotheses analyzed population level trends and focused on major dietary factors such as antioxidants and lipids. More recently, larger dietary patterns beyond individual nutrients have been investigated such as obesity, fast foods, and the Mediterranean diet. Despite some promising hypotheses and findings, there has been no conclusive evidence about the role of specific nutrients, food types, or dietary patterns past early childhood on asthma prevalence. However, diet has been linked to the development of the fetus and child. Breastfeeding provides immunological protection when the infant's immune system is immature and a modest protective effect against wheeze in early childhood. Moreover, maternal diet may be a significant factor in the development of the fetal airway and immune system. As asthma is a complex disease of gene-environment interactions, maternal diet may play an epigenetic role in sensitizing fetal airways to respond abnormally to environmental insults. Recent hypotheses show promise in a biological approach in which the effects of dietary factors on individual physiology and immunology are analyzed before expansion into larger population studies. Thus, collaboration is required by various groups in studying this enigma from epidemiologists to geneticists to immunologists. It is now apparent that this multidisciplinary approach is required to move forward and understand the complexity of the interaction of dietary factors and asthma.

With rare exception, however, the resultant protein products have remained largely intractable as pharmacologic targets. One example is AML1-ETO, the most common translocation reported in acute myeloid leukemia (AML). To identify AML1-ETO modulators, we screened a small molecule library using a chemical genomic approach. Gene expression signatures were used as surrogates for the expression versus loss of the translocation in AML1-ETO-expressing cells. The top classes of compounds that scored in this screen were corticosteroids and dihydrofolate reductase (DHFR) inhibitors. In addition to modulating the AML1-ETO signature, both classes induced evidence of differentiation, dramatically inhibited cell viability, and ultimately induced apoptosis via on-target activity. Furthermore, AML1-ETO-expressing cell lines were exquisitely sensitive to the effects of corticosteroids on cellular viability compared with nonexpressers. The corticosteroids diminished AML1-ETO protein in AML cells in a proteasome-and glucocorticoid receptor-dependent manner. Moreover, these molecule classes demonstrated synergy in combination with standard AML chemotherapy agents and activity in an orthotopic model of AML1-ETO-positive AML. This work suggests a role for DHFR inhibitors and corticosteroids in treating patients with AML1-ETO-positive disease.

Most of these mutations consist of a V600E substitution resulting in constitutive kinase activation. Mutant BRAF thus represents an important therapeutic target in melanoma. In an effort to produce a pre-clinical model of mutant BRAF function in melanoma, we have generated a mouse expressing BRAF V600E targeted to melanocytes. We show that in these transgenic mice, widespread benign melanocytic hyperplasia with histological features of nevi occurs, with biochemical evidence of senescence. Melanocytic hyperplasia progresses to overt melanoma with an incidence dependent on BRAF expression levels. Melanomas show CDKN2A loss, and genetic disruption of the CDKN2A locus greatly enhances melanoma formation, consistent with collaboration between BRAF activation and CDKN2A loss suggested from studies of human melanoma. The development of melanoma also involves activation of the Mapk and Akt signaling pathways and loss of senescence, findings that faithfully recapitulate those seen in human melanomas. This murine model of mutant BRAF-induced melanoma formation thus provides an important tool for identifying further genetic alterations that cooperates with BRAF and that may be useful in enhancing susceptibility to BRAF-targeted therapeutics in melanoma.

However, few studies have addressed the molecular mechanisms through which such important function is exerted. Fatty acid synthase (FASN), a key enzyme that synthesizes long-chain fatty acids and is involved in both embryogenesis and cancer, has been recently proposed as a direct target of p53 family members, including p63 and p73. Here we show that knockdown of either total or Delta N-specific p63 isoforms in squamous cell carcinoma (SCC9) or immortalized prostate epithelial (iPrEC) cells caused a decrease in cell viability by inducing apoptosis without affecting the cell cycle. p63 silencing significantly reduced both the expression and the activity of FASN. Importantly, stable overexpression of either FASN or myristoylated AKT (myr-AKT) was able to partially rescue cells from cell death induced by p63 silencing. FASN induced AKT phosphorylation and a significant reduction in cell viability was observed when FASN-overexpressing SCC9 cells were treated with an AKT inhibitor after p63 knockdown, indicating that AKT plays a major role in FASN-mediated survival. Activated AKT did not cause any alteration in the FASN protein levels but induced its activity, suggesting that the rescue from apoptosis documented in the p63-silenced cells expressing myr-AKT cells may be partially mediated by FASN. Finally, we demonstrated that p63 and FASN expression are positively associated in clinical squamous cell carcinoma samples as well as in the developing prostate. Taken together, our findings demonstrate that FASN is a functionally relevant target of p63 and is required for mediating its pro-survival effects.

Current consensus, based on cytogenetic risk, recommends myeloablative allogeneic stem cell transplantation (SCT) for poor-risk but not for good-risk AML. Allogeneic SCT, autologous transplantation, and consolidation chemotherapy are considered of equivalent benefit for intermediate-risk AML. Objective To quantify relapse-free survival (RFS) and overall survival benefit of allogeneic SCT for AML in CR1 overall and also for good-, intermediate-, and poor-risk AML. Methods Systematic review and meta-analysis of prospective trials evaluating allogeneic SCT vs nonallogeneic SCT therapies for AML in CR1. The search used the combined search terms allogeneic; acut* and leukem*/leukaem*/leucem*/leucaem*/aml; myelo* or nonlympho* in the PubMed, Embase, and Cochrane Registry of Controlled Trials databases in March 2009. The search identified 1712 articles. Study Selection Prospective trials assigning adult patients with AML in CR1 to undergo allogeneic SCT vs nonallogeneic SCT treatment(s) based on donor availability and trials reporting RFS and/or overall survival outcomes on an intention-to-treat, donor vs no-donor basis were identified. Data Extraction Two reviewers independently extracted study characteristics, interventions, and outcomes. Hazard ratios (HRs) with 95% confidence intervals (CIs) were determined. Data Synthesis Overall, 24 trials and 6007 patients were analyzed (5951 patients in RFS analyses and 5606 patients in overall survival analyses); 3638 patients were analyzed by cytogenetic risk (547, 2499, and 592 with good-, intermediate-, and poor-risk AML, respectively). Interstudy heterogeneity was not significant. Fixed-effects meta-analysis was performed. Compared with nonallogeneic SCT, the HR of relapse or death with allogeneic SCT for AML in CR1 was 0.80 (95% CI, 0.74-0.86). Significant RFS benefit of allogeneic SCT was documented for poor- risk (HR, 0.69; 95% CI, 0.57-0.84) and intermediate- risk AML (HR, 0.76; 95% CI, 0.68-0.85) but not for good- risk AML (HR, 1.06; 95% CI, 0.80-1.42). The HR of death with allogeneic SCT for AML in CR1 was 0.90 ( 95% CI, 0.82-0.97). Significant overall survival benefit with allogeneic SCT was documented for poor- risk (HR, 0.73; 95% CI, 0.59-0.90) and intermediate- risk AML (HR, 0.83; 95% CI, 0.74-0.93) but not for good- risk AML (HR, 1.07; 95% CI, 0.83-1.38). Conclusion Compared with nonallogeneic SCT therapies, allogeneic SCT has significant RFS and overall survival benefit for intermediate- and poor- risk AML but not for good- risk AML in first complete remission.

Our previous work has shown that APP processing and A beta production are regulated by the extracellular matrix protein Reelin. In the present study, we examined whether Reelin interacts with APP, and the functional consequences of that interaction in vitro. Using coimmunoprecipitation, we found that Reelin interacted with APP through the central domain of Reelin (repeats 3-6) and the E1 extracellular domain of APP. Reelin increased cell surface levels of APP and decreased endocytosis of APP in hippocampal neurons in vitro. In vivo, Reelin levels were increased in brains of APP knock-out mice and decreased in APP-overexpressing mice. RNA interference knockdown of APP decreased neurite outgrowth in vitro and prevented Reelin from increasing neurite outgrowth. Knock-out of APP or Reelin decreased dendritic arborization in cortical neurons in vivo, and APP overexpression increased dendritic arborization. APP and Reelin have previously been shown to promote neurite outgrowth through interactions with integrins. We confirmed that APP interacted with alpha 3 beta 1 integrin, and alpha 3 beta 1 integrin altered APP trafficking and processing. Addition of an alpha 3 beta 1 integrin antibody prevented APP and Reelin-induced neurite outgrowth. These findings demonstrate that Reelin interacts with APP, potentially having important effects on neurite development. C1 [Hoe, Hyang-Sook; Rebeck, G.

TI Amino-Terminal Pro-B-Type Natriuretic Peptide and High-Sensitivity C-Reactive Protein as Predictors of Sudden Cardiac Death Among Women SO CIRCULATION LA English DT Article DE death, sudden; epidemiology; natriuretic peptides; risk factors; women ID CARDIOVASCULAR EVENTS; MYOCARDIAL-INFARCTION; CORONARY DEATH; UNITED-STATES; RISK; HEART; ARRHYTHMIAS; POPULATION; OUTCOMES; FAILURE AB Background-Plasma concentrations of N-terminal pro-B-type natriuretic peptide (NT-proBNP) have been found to predict risk of sudden cardiac death (SCD) in patients with known cardiac disease, and C-reactive protein levels have been found to predict risk among apparently healthy men. However, there are no data on SCD risk prediction for either of these markers in a population of women unselected on the basis of cardiovascular disease. Methods and Results-In a prospective, nested, case-control analysis within the 121 700-participant Nurses' Health Study, 99 cases of definite or probable SCD were identified and matched to 294 controls. In multivariable models that adjusted for coronary heart disease risk factors, glomerular filtration rate, and other biomarkers, the trend across quartiles approached significance for NT-proBNP (rate ratio=2.37 for comparison of the highest and lowest quartile; P for trend=0.05) but not for high-sensitivity C-reactive protein (P for trend=0.60). When examined continuously, both NT-proBNP and high-sensitivity C-reactive protein were significantly associated with SCD risk in age-and fasting-adjusted models (P for linear trend=0.04 and 0.03). Adjustment for coronary heart disease risk factors and other biomarkers strengthened the relationship with NT-proBNP and SCD (relative risk for 1-SD increment=1.49; 95% confidence interval, 1.09 to 2.05; P=0.01) but eliminated the relationship with high-sensitivity C-reactive protein (P=0.34). Women with NT-proBNP levels above the prespecified cut point of 389 pg/mL were at a markedly increased risk of SCD in both models (rate ratio=5.68; 95% confidence interval, 1.78 to 18.2; P=0.003). Conclusions-In this population of women, baseline levels of NT-proBNP were associated with subsequent risk of SCD. If this association is confirmed in larger prospectively studied populations, these findings might provide another useful marker contributing to efforts to screen and prevent SCD among women.

Tadalafil, a phosphodiesterase type-5 inhibitor, increases cGMP, the final mediator in the nitric oxide pathway. Methods and Results-In this 16-week, double-blind, placebo-controlled study, 405 patients with pulmonary arterial hypertension (idiopathic or associated), either treatment-naive or on background therapy with the endothelin receptor antagonist bosentan, were randomized to placebo or tadalafil 2.5, 10, 20, or 40 mg orally once daily. The primary end point was the change from baseline to week 16 in the distance walked in 6 minutes. Changes in World Health Organization functional class, clinical worsening, and health-related quality of life were also assessed. Patients completing the 16-week study could enter a long-term extension study. Tadalafil increased the distance walked in 6 minutes in a dose-dependent manner; only the 40-mg dose met the prespecified level of statistical significance (P<0.01). Overall, the mean placebo-corrected treatment effect was 33 m (95% confidence interval, 15 to 50 m). In the bosentan-naive group, the treatment effect was 44 m (95% confidence interval, 20 to 69 m) compared with 23 m (95% confidence interval, -2 to 48 m) in patients on background bosentan therapy. Tadalafil 40 mg improved the time to clinical worsening (P=0.041), incidence of clinical worsening (68% relative risk reduction; P=0.038), and health-related quality of life. The changes in World Health Organization functional class were not statistically significant. The most common treatment-related adverse events reported with tadalafil were headache, myalgia, and flushing. Conclusions-In patients with pulmonary arterial hypertension, tadalafil 40 mg was well tolerated and improved exercise capacity and quality of life measures and reduced clinical worsening.

Methods: We studied 2,509 well-functioning black and white elders enrolled in a prospective study. Cognitive function was measured using the Modified Mini-Mental State Examination at baseline and years 3, 5, and 8. Random effects models were used to classify participants as cognitive maintainers (cognitive change slope >= 0), minor decliners (slope <0 and >1 SD below mean), or major decliners (slope <= 1 SD below mean). Logistic regression was used to identify domain-specific factors associated with being a maintainer vs a minor decliner. Results: Over 8 years, 30% of the participants maintained cognitive function, 53% showed minor decline, and 16% had major cognitive decline. In the multivariate model, baseline variables significantly associated with being a maintainer vs a minor decliner were age (odds ratio [OR] = 0.65, 95% confidence interval [CI] 0.55-0.77 per 5 years), white race (OR = 1.72, 95% CI 1.30-2.28), high school education level or greater (OR = 2.75, 95% CI 1.78-4.26), ninth grade literacy level or greater (OR = 4.85, 95% CI 3.00-7.87), weekly moderate/vigorous exercise (OR = 1.31, 95% CI 1.06-1.62), and not smoking (OR = 1.84, 95% CI 1.14-2.97). Variables associated with major cognitive decline compared to minor cognitive decline are reported. Conclusion: Elders who maintain cognitive function have a unique profile that differentiates them from those with minor decline. Importantly, some of these factors are modifiable and thus may be implemented in prevention programs to promote successful cognitive aging. Further, factors associated with maintenance may differ from factors associated with major cognitive decline, which may impact prevention vs treatment strategies.

After secretion in plasma, length is regulated by hydrodynamic shear force-dependent unfolding of the A2 domain, which is then cleaved by a specific protease. The 1.9-angstrom crystal structure of the A2 domain demonstrates evolutionary adaptations to this shear sensor function. Unique among VWF A (VWA) domains, A2 contains a loop in place of the alpha 4 helix, and a cis-proline. The central beta 4-strand is poorly packed, with multiple side-chain rotamers. The Tyr-Met cleavage site is buried in the beta 4-strand in the central hydrophobic core, and the Tyr structurally links to the C-terminal alpha 6-helix. The alpha 6-helix ends in 2 Cys residues that are linked by an unusual vicinal disulfide bond that is buried in a hydrophobic pocket. These features may narrow the force range over which unfolding occurs and may also slow refolding. Von Willebrand disease mutations, which presumably lower the force at which A2 unfolds, are illuminated by the structure.

The display of self-antigens by thymic epithelial cells is key to inducing tolerance in the T lymphocyte compartment, a process enhanced by the Aire transcription factor. Using a doxycycline-regulated transgene to target Aire expression to the thymic epithelium, complementing the Aire knockout in a temporally controlled manner, we find that Aire is essential in the perinatal period to prevent the multiorgan autoimmunity that is typical of Aire deficiency. Surprisingly, Aire could be shut down soon thereafter and remain off for long periods, with few deleterious consequences. The lymphopenic state present in neonates was a factor in this dichotomy because inducing lymphopenia during Aire turnoff in adults recreated the disease, which, conversely, could be ameliorated by supplementing neonates with adult lymphocytes. In short, Aire expression during the perinatal period is both necessary and sufficient to induce long-lasting tolerance and avoid autoimmunity. Aire-controlled mechanisms of central tolerance are largely dispensable in the adult, as a previously tolerized T cell pool can buffer newly generated autoreactive T cells that might emerge.

A complete dissection was made of the primary HIV-1-specific T cell response induced in three acutely infected patients. Cellular assays, together with new algorithms which identify sites of positive selection in the virus genome, showed that primary HIV-1-specific T cells rapidly select escape mutations concurrent with falling virus load in acute infection. Kinetic analysis and mathematical modeling of virus immune escape showed that the contribution of CD8 T cell-mediated killing of productively infected cells was earlier and much greater than previously recognized and that it contributed to the initial decline of plasma virus in acute infection. After virus escape, these first T cell responses often rapidly waned, leaving or being succeeded by T cell responses to epitopes which escaped more slowly or were invariant. These latter responses are likely to be important in maintaining the already established virus set point. In addition to mutations selected by T cells, there were other selected regions that accrued mutations more gradually but were not associated with a T cell response. These included clusters of mutations in envelope that were targeted by NAbs, a few isolated sites that reverted to the consensus sequence, and bystander mutations in linkage with T cell-driven escape.

Within the tumor micro-environment, the secreted protein milk fat globule epidermal growth factor-8 (MFG-E8) stimulates disease progression through coordinated alpha(v)beta(3) integrin signaling in tumor and host cells. MFG-E8 enhances tumor cell survival, invasion, and angiogenesis, and contributes to local immune suppression. We show that systemic MFG-E8 blockade cooperates with cytotoxic chemotherapy, molecularly targeted therapy, and radiation therapy to induce destruction of various types of established mouse tumors. The combination treatments evoke extensive tumor cell apoptosis that is coupled to efficient dendritic cell cross-presentation of dying tumor cells. This linkage engenders potent antitumor effector T cells but inhibits FoxP3(+) T reg cells, thereby achieving long-term protective immunity. Collectively, these findings suggest that systemic MFG-E8 blockade might intensify the antitumor activities of existing therapeutic regimens through coordinated cell-autonomous and immune-mediated mechanisms.

DDM contains an unusual acylation motif and a peptide sequence present only in mycobacteria, but its discovery raises the possibility that ribosomally produced viral or mammalian proteins that commonly undergo lipidation might also function as antigens. To test this, we measured T cell responses to synthetic acylpeptides that mimic lipoproteins produced by cells and viruses. CD1c presented an N-acyl glycine dodecamer peptide (lipo-12) to human T cells, and the response was specific for the acyl linkage as well as the peptide length and sequence. Thus, CD1c represents the second member of the CD1 family to present lipopeptides. lipo-12 was efficiently recognized when presented by intact cells, and unlike DDM, it was inactivated by proteases and augmented by protease inhibitors. Although lysosomes often promote antigen presentation by CD1, rerouting CD1c to lysosomes by mutating CD1 tail sequences caused reduction in lipo-12 presentation. Thus, although certain antigens require antigen processing in lysosomes, others are destroyed there, providing a hypothesis for the evolutionary conservation of large CD1 families containing isoforms that survey early endosomal pathways.

Uncertainties in dosimetric prediction can significantly degrade an otherwise optimal plan. In this work, we introduce a robust optimization method which handles dosimetric errors and warrants for high-quality IMRT plans. Unlike other dose error estimations, we do not rely on the detailed knowledge about the sources of the uncertainty and use a generic error model based on random perturbation. This generality is sought in order to cope with a large variety of error sources. We demonstrate the method on a clinical case of lung cancer and show that our method provides plans that are more robust against dosimetric errors and are clinically acceptable. In fact, the robust plan exhibits a two-fold improved equivalent uniform dose compared to the non-robust but optimized plan. The achieved speedup will allow computationally extensivemulti-criteria or beam-angle optimization approaches to warrant for dosimetrically relevant plans.

The dyskinetic episodes are initially paroxysmal but may become constant. With increasing age they may lessen or even disappear. The previous study excluded nine candidate genes chosen for their association with myokymia or chorea and two regions containing single or clustered ion channel genes. We now report identification by whole genome linkage analysis of a broad region on chromosome 3p21-3q21 that segregates with the disease in all 10 affected members in three generations who participated in the study. GENEHUNTER-MODSCORE Version 2.0.1 provided a maximum multipoint LOD score of 3.099. No other disorders primarily characterized by myokymia, dystonia, or chorea are known to map to this region. Identification of additional families with FDFM may narrow the critical region and facilitate the choice of candidate genes for further analysis. (C) 2008 Wiley-Liss, Inc.

Furthermore, pharmacologic inhibition of Hh signaling with a potent and selective small molecule antagonist has no substantive effect on hematopoiesis in the mouse. In addition, Hh signaling is not required for the development of MLL-AF9-mediated acute myeloid leukemia (AML). Taken together, these data demonstrate that Hh signaling is dispensable for normal hematopoietic development and hematopoietic stem cell function, indicating that targeting of Hh signaling in solid tumors is not likely to result in hematopoietic toxicity. Furthermore, the Hh pathway may not be a compelling target in certain hematopoietic malignancies.

Cleaved VWF is activated by hydrodynamic forces found in arteriolar bleeding to promote hemostasis, whereas uncleaved VWF is activated at lower, physiologic shear stresses and causes thrombosis. Single-molecule experiments demonstrate that elongational forces in the range experienced by VWF in the vasculature unfold the A2 domain, and only the unfolded A2 domain is cleaved by ADAMTS13. In shear flow, tensile force on a VWF multimer increases with the square of multimer length and is highest at the middle, providing an efficient mechanism for homeostatic regulation of VWF size distribution by force-induced A2 unfolding and cleavage by ADAMTS13, as well as providing a counterbalance for VWF-mediated platelet aggregation.

T helper 17 (T(H)17) cells, characterized by their production of interleukin-17, have emerged as important and broad mediators of autoimmunity. Here we show that the small molecule halofuginone (HF) selectively inhibits mouse and human T(H)17 differentiation by activating a cytoprotective signaling pathway, the amino acid starvation response (AAR). Inhibition of T(H)17 differentiation by HF is rescued by the addition of excess amino acids and is mimicked by AAR activation after selective amino acid depletion. HF also induces the AAR in vivo and protects mice from T(H)17-associated experimental autoimmune encephalomyelitis. These results indicate that the AAR pathway is a potent and selective regulator of inflammatory T cell differentiation in vivo.

TI Agenetic screen in zebrafish defines a hierarchical network of pathways required for hematopoietic stem cell emergence SO BLOOD LA English DT Article ID ENDOTHELIAL-GROWTH-FACTOR; GONAD-MESONEPHROS REGION; DIAMOND-BLACKFAN ANEMIA; DEFINITIVE HEMATOPOIESIS; ARTERIAL DEVELOPMENT; NOTCH; GENE; DIFFERENTIATION; EXPRESSION; SPADETAIL AB Defining the genetic pathways essential for hematopoietic stem cell (HSC) development remains a fundamental goal impacting stem cell biology and regenerative medicine. To genetically dissect HSC emergence in the aorta-gonad-mesonephros (AGM) region, we screened a collection of insertional zebrafish mutant lines for expression of the HSC marker, c-myb. Nine essential genes were identified, which were subsequently binned into categories representing their proximity to HSC induction. Using overexpression and loss-of-function studies in zebrafish, we ordered these signaling pathways with respect to each other and to the Vegf, Notch, and Runx programs. Overexpression of vegf and notch is sufficient to induce HSCs in the tbx16 mutant, despite a lack of axial vascular organization. Although embryos deficient for artery specification, such as the phospholipase C gamma-1 (plc gamma 1) mutant, fail to specify HSCs, overexpression of notch or runx1 can rescue their hematopoietic defect. The most proximal HSC mutants, such as hdac1, were found to have no defect in vessel or artery formation. Further analysis demonstrated that hdac1 acts downstream of Notch signaling but upstream or in parallel to runx1 to promote AGM hematopoiesis. Together, our results establish a hierarchy of signaling programs required and sufficient for HSC emergence in the AGM.

TI Elevated levels of soluble P-selectin in mice alter blood-brain barrier function, exacerbate stroke, and promote atherosclerosis SO BLOOD LA English DT Article ID OBSTRUCTIVE SLEEP-APNEA; VASCULAR ENDOTHELIAL-CELLS; DEFICIENT MICE; ISCHEMIC-STROKE; PLATELET ACTIVATION; ALZHEIMERS-DISEASE; CYTOPLASMIC DOMAIN; APOLIPOPROTEIN-E; TISSUE FACTOR; IN-VIVO AB Cerebrovascular and cardiovascular diseases are a major cause of morbidity and mortality. Soluble P-selectin (sP-selectin) is a biomarker for platelet/endothelial activation and is considered a risk factor for vascular disease. sP-selectin enhances procoagulant activity by inducing leukocyte-derived microparticle production and promotes activation of leukocyte integrins. However, it is not known whether it directly contributes to vascular complications. We investigated the effect of in-creased levels of sP-selectin on blood-brain barrier (BBB) function, stroke outcome, and atherosclerosis by comparing wild-type mice with P-sel(Delta CT/Delta CT) mice in which the endogenous P-selectin gene was replaced with a mutant that produces abnormally high plasma levels of sP-selectin. P-sel(Delta CT/Delta CT) mice presented several abnormalities, including (1) higher BBB permeability, with 25% of the animals showing differential permeability between the right and left hemispheres; (2) altered social behavior with increased aggression; (3) larger infarcts in the middle cerebral artery occlusion ischemic stroke model; and (4) increased susceptibility to atherosclerotic, macrophage-rich lesion development in both male and female mice on the apoE(-/-) genetic background. Thus, elevated sP-selectin is not only a biomarker for vascular disease, but also may contribute directly to atherosclerosis and cerebrovascular complications.

TI Col11a2 Deletion Reveals the Molecular Basis for Tectorial Membrane Mechanical Anisotropy SO BIOPHYSICAL JOURNAL LA English DT Article ID ARTICULAR-CARTILAGE; HEARING-LOSS; MOTION; COLLAGEN; MOUSE; ORGAN; MODEL; CORTI; LOCALIZATION; ORGANIZATION AB The tectorial membrane (TM) has a significantly larger stiffness in the radial direction than other directions, a prominent mechanical anisotropy that is believed to be critical for the proper functioning of the cochlea. To determine the molecular basis of this anisotropy, we measured material properties of TMs from mice with a targeted deletion of Col11a2, which encodes for collagen XI. In light micrographs, the density of TM radial collagen fibers was lower in Col11a2-/- mice than wild-types. Tone-evoked distortion product otoacoustic emission and auditory brainstem response measurements in Col11a2-/- mice were reduced by 30-50 dB independent of frequency as compared with wild-types, showing that the sensitivity loss is cochlear in origin. Stress-strain measurements made using osmotic pressure revealed no significant dependence of TM bulk compressibility on the presence of collagen XI. Charge measurements made by placing the TM as an electrical conduit between two baths revealed no change in the density of charge affixed to the TM matrix in Col11a2-/- mice. Measurements of mechanical shear impedance revealed a 5.5 +/- 0.8 dB decrease in radial shear impedance and a 3.3 +/- 0.3 dB decrease in longitudinal shear impedance resulting from the Col11a2 deletion. The ratio of radial to longitudinal shear impedance fell from 1.8 +/- 0.7 for TMs from wild-type mice to 1.0 +/- 0.1 for those from Col11a2-/- mice. These results show that the organization of collagen into radial fibrils is responsible for the mechanical anisotropy of the TM. This anisotropy can be attributed to increased mechanical coupling provided by the collagen fibrils. Mechanisms by which changes in TM material properties may contribute to the threshold elevation in Col11a2-/- mice are discussed.

Methods: We conducted a retrospective national cohort study using Veterans Affairs administrative data including subjects >= 65 years of age hospitalized with a COPD exacerbation. Our primary analysis was a multilevel model with the dependent variable of 90-day mortality and hospital as a random effect, controlling for preexisting comorbid conditions, demographics, and other medications prescribed. Results: We identified 11,212 subjects with a mean age of 74.0 years, 98% were male, and 12.4% of subjects died within 90-days of hospital presentation. In this cohort, 20.3% of subjects were using statins, 32.0% were using ACE inhibitors or angiotensin II receptor blockers (ARB). After adjusting for potential confounders, current statin use (odds ratio 0.51, 95% confidence interval 0.40-0.64) and ACE inhibitor/ARB use (0.55, 0.46-0.66) were significantly associated with decreased 90-day mortality. Conclusion: Use of statins and ACE inhibitors prior to admission is associated with decreased mortality in subjects hospitalized with a COPD exacerbation. Randomized controlled trials are needed to examine whether the use of these medications are protective for those patients with COPD exacerbations.

Using short hairpin RNAs to deplete K-Ras in lung and pancreatic cancer cell lines harboring K-ras mutations, two classes were identified-lines that do or do not require K-Ras to maintain viability. Comparing these two classes of cancer cells revealed a gene expression signature in K-Ras-dependent cells, associated with a well-differentiated epithelial phenotype, which was also seen in primary tumors. Several of these genes encode pharmacologically tractable proteins, such as Syk and Ron kinases. and integrin beta 6, depletion of which induces epithelial-mesenchymal transformation (EMT) and apoptosis specifically in K-Ras-dependent cells. These findings indicate that epithelial differentiation and tumor cell viability are associated, and that EMT regulators in "K-Ras-addicted" cancers represent candidate therapeutic targets.

This effect must be balanced against an increased bleeding risk. We aimed to characterize the effect of prasugrel with respect to the type, size, and timing of MI using the universal classification of MI. Methods and Results-We studied 13 608 patients with acute coronary syndrome undergoing percutaneous coronary intervention randomized to prasugrel or clopidogrel and treated for 6 to 15 months in the Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition With Prasugrel-Thrombolysis in Myocardial Infarction (TRITON-TIMI 38). Each MI underwent supplemental classification as spontaneous, secondary, or sudden cardiac death (types 1, 2, and 3) or procedure related (Types 4 and 5) and examined events occurring early and after 30 days. Prasugrel significantly reduced the overall risk of MI (7.4% versus 9.7%; hazard ratio [HR], 0.76; 95% confidence interval [CI], 0.67 to 0.85; P < 0.0001). This benefit was present for procedure-related MIs (4.9% versus 6.4%; HR, 0.76; 95% CI, 0.66 to 0.88; P = 0.0002) and nonprocedural (type 1, 2, or 3) MIs (2.8% versus 3.7%; HR, 0.72; 95% CI, 0.59 to 0.88; P = 0.0013) and consistently across MI size, including MIs with a biomarker peak >= 5 times the reference limit (HR. 0.74; 95% CI, 0.64 to 0.86; P = 0.0001). In landmark analyses starting at 30 days, patients treated with prasugrel had a lower risk of any MI (2.9% versus 3.7%; HR, 0.77; P = 0.014), including nonprocedural MI (2.3% versus 3.1%; HR, 0.74; 95% CI, 0.60 to 0.92; P = 0.0069). Conclusion-Treatment with prasugrel compared with clopidogrel for up to 15 months in patients with acute coronary syndrome undergoing percutaneous coronary intervention significantly reduces the risk of MIs that are procedure related and spontaneous and those that are small and large, including new MIs occurring during maintenance therapy.

We assessed the relationship between instantaneous ejection-phase pressure and myocardial stress and the effect of arterial wave reflections on myocardial stress in hypertensive and normotensive adults. Methods and Results-We studied 42 untreated hypertensive, 42 treated hypertensive, and 42 normotensive adults with normal LV ejection fraction. Time-resolved central pressure, flow, and LV geometry were measured with carotid tonometry, Doppler, and speckle-tracking echocardiography for computation of arterial load and time-varying circumferential and longitudinal myocardial stress. In all 3 groups, peak myocardial stress typically occurred in early systole (within the first 100 milliseconds of ejection), followed by a marked midsystolic shift in the pressure-stress relationship, which favored lower late systolic stress values (P < 0.001) relative to pressure. The mean magnitude of this midsystolic shift was quantitatively important in all 3 groups (circumferential stress, 144 to 148 kdynes/cm(2)) and was independently predicted by a higher LV ejection fraction and ratio of LV end-diastolic cavity to wall volume. Time of peak myocardial stress independently correlated with time of the first systolic but not with time of the second systolic central pressure peak. Conclusions-Peak myocardial stress occurs in early systole, before important contributions of reflected waves to central pressure. In the presence of normal LV ejection fraction, a midsystolic shift in the pressure-stress relationship protects cardiomyocytes against excessive late systolic stress (despite pressure augmentation associated with wave reflections), a coupling mechanism that may be altered in various disease states.

TI Risk of dementia and AD with prior exposure to NSAIDs in an elderly community-based cohort SO NEUROLOGY LA English DT Article ID RANDOMIZED CONTROLLED-TRIAL; ALZHEIMERS-DISEASE; APOLIPOPROTEIN-E; ANTIINFLAMMATORY DRUGS; CACHE COUNTY; ONSET; AGE; ROFECOXIB; NAPROXEN AB Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) may prevent Alzheimer dementia (AD). Methods: We analyzed the association of prior NSAID exposure with incident dementia and AD in the Adult Changes in Thought population-based cohort aged >= 65 years (median 74.8) at enrollment. Participants were members of Group Health, which provided computerized pharmacy dispensing records from 1977 onward. We studied 2,736 dementia-free enrollees with extensive prior pharmacy data, following them biennially for up to 12 years to identify dementia and AD. Cox proportional hazards regression assessed association of dementia or AD with NSAID use graded in standard daily doses (SDD) dispensed over 2 years (e.g., heavy use = 500 + SDD), with some analyses also adding consecutive biennial self-reports of NSAID use. Results: Pharmacy records identified 351 participants (12.8%) with history of heavy NSAID use at enrollment. Another 107 became heavy users during follow-up. Some 476 individuals developed incident dementia, 356 with AD (median onset ages 83.5 and 83.8 years). Contrary to the hypothesis that NSAIDs protect against AD, pharmacy-defined heavy NSAID users showed increased incidence of dementia and AD, with adjusted hazard ratios of 1.66 (95% confidence interval, 1.24-2.24) and 1.57 (95% confidence interval, 1.10-2.23). Addition of self-reported exposure data did not alter these results. Conclusions: These findings differ from those of other studies with younger cohorts. The results observed elsewhere may reflect delayed onset of Alzheimer dementia (AD) in nonsteroidal anti-inflammatory drug (NSAID) users. Conceivably, such delay could result in increased AD incidence in late old age. The relation of NSAID use and AD pathogenesis needs further investigation.

TI Natalizumab treatment is associated with peripheral sequestration of proinflammatory T cells SO NEUROLOGY LA English DT Article ID EXPERIMENTAL AUTOIMMUNE ENCEPHALOMYELITIS; PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY; MULTIPLE-SCLEROSIS PATIENTS; CENTRAL-NERVOUS-SYSTEM; TRANSCRIPTION FACTOR; REGULATORY CELLS; EXPRESSION; INTEGRIN; BRAIN; ANTIBODIES AB Background: Natalizumab is an antibody directed against integrin alpha 4 that reduces disease activity in patients with multiple sclerosis (MS) by blocking migration of T and B cells into the CNS. The goal of this study was to characterize the effects of natalizumab treatment on cytokine production and expression of activation markers, costimulatory molecules, and trafficking determinants on CD4(+) and CD8(+) T cells. Methods: In a longitudinal study, we investigated the expression of surface makers and cytokine expression on peripheral blood lymphocytes from 28 patients with MS who started natalizumab treatment and were followed for 1 year. A mixed effects model was used to compare pretreatment to on-treatment measurements. Results: The frequency of CD4(+) T cells producing interferon-gamma, tumor necrosis factor, and interleukin (IL)-17 upon anti-CD3 stimulation increased 6 months after initiation of natalizumab treatment and remained elevated throughout the follow-up. The frequency of CD4(+) T cells expressing CD25, HLA-DR, and CCR6 ex vivo was increased at one or more time points during treatment. Among CD8(+) T cells, the frequency of cells producing IL-2 and IL-17 after stimulation was increased during natalizumab treatment, as was the frequency of CD8(+) T cells expressing CD58 and CCR5 ex vivo. The increase in the frequency of activated cells could not be replicated by in vitro exposure to natalizumab. Conclusion: Natalizumab treatment increases the percentage of activated leukocytes producing proinflammatory cytokines in blood, presumably due to sequestration of activated cells in the peripheral circulation.

To identify genetic variants associated with susceptibility and phenotypes in sporadic ALS, we performed a genome-wide SNP analysis in sporadic ALS cases and controls. A total of 288,357 SNPs were screened in a set of 1,821 sporadic ALS cases and 2,258 controls from the U. S. and Europe. Survival analysis was performed using 1,014 deceased sporadic cases. Top results for susceptibility were further screened in an independent sample set of 538 ALS cases and 556 controls. SNP rs1541160 within the KIFAP3 gene (encoding a kinesin-associated protein) yielded a genome-wide significant result ( P = 1.84 x 10(-8)) that withstood Bonferroni correction for association with survival. Homozygosity for the favorable allele (CC) conferred a 14.0 months survival advantage. Sequence, genotypic and functional analyses revealed that there is linkage disequilibrium between rs1541160 and SNP rs522444 within the KIFAP3 promoter and that the favorable alleles of rs1541160 and rs522444 correlate with reduced KIFAP3 expression. No SNPs were associated with risk of sporadic ALS, site of onset, or age of onset. We have identified a variant within the KIFAP3 gene that is associated with decreased KIFAP3 expression and increased survival in sporadic ALS. These findings support the view that genetic factors modify phenotypes in this disease and that cellular motor proteins are determinants of motor neuron viability.

Although rarely elicited during the course of natural infection or upon conventional vaccination, the membrane-proximal ectodomain region (MPER) of the HIV-1 glycoprotein of M(r) 41,000 (gp41) envelope protein subunit is the target of 3 such human broadly neutralizing antibodies (BNAbs): 4E10, 2F5, and Z13e1. How these BNAbs bind to their lipid-embedded epitopes and mediate antiviral activity is unclear, but such information might offer important insight into a worldwide health imperative. Here, EPR and NMR techniques were used to define the manner in which these BNAbs differentially recognize viral membrane-encrypted residues configured within the L-shaped helix-hinge-helix MPER segment. Two distinct modes of antibody-mediated interference of viral infection were identified. 2F5, like 4E10, induces large conformational changes in the MPER relative to the membrane. However, although 4E10 straddles the hinge and extracts residues W672 and F673, 2F5 lifts up residues N-terminal to the hinge region, exposing L669 and W670. In contrast, Z13e1 effects little change in membrane orientation or conformation, but rather immobilizes the MPER hinge through extensive rigidifying surface contacts. Thus, BNAbs disrupt HIV-1MPERfusogenic functions critical for virus entry into human CD4 T cells and macrophages either by preventing hinge motion or by perturbing MPER orientation. HIV-1 MPER features important for targeted vaccine design have been revealed, the implications of which extend to BNAb targets on other viral fusion proteins.

This was a retrospective analysis utilizing the ED component of the 1996-2005 National Hospital Ambulatory Medical Care Survey (NHAMCS). The authors included NHAMCS ED entries aged >= 18 years with a diagnosis of UTI or pyelonephritis; pregnancy was excluded. Records were divided into 18-64 years ("adults") and >= 65 years ("elders"). Primary outcome measures were prescription of TMP-SMX monotherapy, fluoroquinolone monotherapy, and combination therapy with two or more antibiotics. Estimated visit totals and rates were calculated and trends analyzed. From 1996 to 2005, there were 5 million elder ED visits for UTI or pyelonephritis. Approximately 9.4% (95% confidence interval [CI] = 7.9% to 11%) of elders received TMP-SMX monotherapy with rates decreasing over time (p-value for trend = 0.031). Overall, 35% (95% CI = 32% to 38%) of elders received fluoroquinolone monotherapy, which increased from 21% (95% CI = 14% to 27%) in 1996 to 45% (95% CI = 39% to 50%) in 2005 (p-value for trend < 0.001). Therapy with a fluoroquinolone plus a second antibiotic was used in only 4.2% (95% CI = 3.1% to 5.3%) of older patients. From 1996 to 2005, TMP-SMX monotherapy in elder ED patients decreased while fluoroquinolone therapy increased. The majority of older patients receiving fluoroquinolone therapy received a single agent. Given the continued prevalence of monotherapy for elder ED patients with UTI or pyelonephritis, antibiotic resistance patterns in these patients should be better characterized to ensure institution of appropriate empiric therapy.

TI Paramedic and Emergency Medical Technicians Views on Opportunities and Challenges When Forgoing and Halting Resuscitation in the Field SO ACADEMIC EMERGENCY MEDICINE LA English DT Article DE resuscitation; ethics; emergency medical services; prehospital care; cardiac arrest ID CARDIAC-ARREST; QUALITY; DEATH AB The objective was to assess paramedic and emergency medical technicians (EMT) perspectives and decision-making after a policy change that allows forgoing or halting resuscitation in prehospital atraumatic cardiac arrest. Five semistructured focus groups were conducted with 34 paramedics and 2 EMTs from emergency medical services (EMS) agencies within Los Angeles County (LAC), 6 months after a policy change that allowed paramedics to forgo or halt resuscitation in the field under certain circumstances. Participants had an overwhelmingly positive view of the policy; felt it empowered their decision-making abilities; and thought the benefits to patients, family, EMS, and the public outweighed the risks. Except under certain circumstances, such as when the body was in public view or when family members did not appear emotionally prepared to have the body left on scene, they felt the policy improved care. Assuming that certain patient characteristics were present, decisions by paramedics about implementing the policy in the field involve many factors, including knowledge and comfort with the new policy, family characteristics (e.g., agreement), and logistics regarding the place of arrest (e.g., size of space). Paramedic and EMT experiences with and attitudes toward forgoing resuscitation, as well as group dynamics among EMS leadership, providers, police, and ED staff, also play a role. Participants view the ability to forgo or halt resuscitation in the field as empowering and do not believe it presents harm to patients or families under most circumstances. Factors other than patient clinical characteristics, such as knowledge and attitudes toward the policy, family emotional preparedness, and location of arrest, affect whether paramedics will implement it.

We describe a general approach to the construction of phosphorescent nanosensors with tunable spectral characteristics, variable degrees of quenching, and a high selectivity for oxygen. The probes are based on bright phosphorescent Pt and Pd complexes of porphyrins and symmetrically pi-extended porphyrins (tetrabenzoporphyrins and tetranaphthoporphyrins). pi-Extension of the core macrocycle allows tuning of the spectral parameters of the probes in order to meet the requirements of a particular imaging application (e.g., oxygen tomography versus planar microscopic imaging). Metalloprophyrins are encapsulated into poly(arylglycine) dendrimers, which fold in aqueous environments and create diffusion barriers for oxygen, making it possible to regulate the sensitivity and the dynamic range of the method. The periphery of the dendrimers is modified with poly(ethylene glycol) residues, which enhance the probe's solubility, diminish toxicity, and help prevent interactions of the probes with the biological environment. The probe's parameters were measured under physiological conditions and shown to be unaffected by the presence of biomacromolecules. The performance of the probes was demonstrated in applications, including in vivo microscopy of vascular pO(2) in the rat brain.

At an average follow-up of 21 months (range, 4 to 60 months), the improvement in total arc of forearm rotation averaged 87 degrees (range, 0 degrees to 160 degrees), from an average of 49 degrees to an average of 136 degrees (p < 0.001). The proportion of patients with occasional or continuous pain after the Darrach procedure (7 after vs. 16 prior; p = 0.04) was significantly reduced. Only two patients had reoperation related to the residual ulna.

A double-blind, placebo-controlled trial of rosiglitazone for clozapine-induced glucose metabolism impairment in patients with Schizophrenia. The primary purpose of this 8-week double-blind, placebo-controlled trial of rosiglitazone 4 mg/day was to examine its effect on insulin sensitivity index (SI) and glucose utilization (SG) in clozapine-treated subjects with schizophrenia with insulin resistance. Eighteen subjects were randomized and accessed with a Frequently Sampled Intravenous Glucose Tolerance Test (FSIVGTT) at baseline and at week 8 to estimate SG and SI. Controlling for the baseline, comparing the rosiglitazone group with placebo group, there was a non-significant improvement in SG (0.016 +/- 0.006-0.018 +/- 0.008, effect size = 0.23, P = 0.05) with a trend of improvement in SI in the rosiglitazone group (4.6 +/- 2.8-7.8 +/- 6.7, effect size = 0.18, P = 0.08). There was a significant reduction in small low-density lipoprotein cholesterol (LDL-C) particle number (987 +/- 443-694 +/- 415, effect size = 0.30, P = 0.04). Rosiglitazone may have a role in addressing insulin resistance and lipid abnormalities associated with clozapine. C1 [Henderson, D. C.; Fan, X.; Sharma, B.; Borba, C.

Although stem and progenitor cells are exquisitely sensitive to oxidant stress, they have not been well studied in MnSOD2-manipulated mouse models. Patterns of proliferation and differentiation of cultured myoblasts (muscle progenitor cells), PI3-Akt signaling during differentiation, and the maintenance of mitochondrial mass with aging using myoblasts from young (3-4 week old) and aged (27-29 months old) MnSOD2-overexpressing (Sod2-Tg) and heterozygote (Sod2(+/-)) mice were characterized by us. Overexpression of MnSOD2 in myoblasts had a protective effect on mitochondrial DNA abundance and some aspects of mitochondrial function with aging, and preservation of differentiation potential. Sod2 deficiency resulted in defective signaling in the PI3-Akt pathway, specifically impaired phosphorylation of Akt at Ser473 and Thr308 in young myoblasts, and decreased differentiation potential. Compared with young myoblasts, aged myoblast Akt was constitutively phosphorylated, unresponsive to mitogen signaling, and indifferent to MnSOD2 levels. These data suggest that specific sites in the PI3K-Akt pathway are more sensitive to increased superoxide levels than to the increased hydrogen peroxide levels generated in Sod2-transgenic myoblasts. In wild-type myoblasts, aging was associated with significant loss of mitochondrial DNA relative to chromosomal DNA, but MnSOD2 overexpression was associated with maintained myoblast mitochondrial DNA with aging.

Design and methods: Literature and conference abstract review of studies assessing the association between adherence to antiretroviral therapy and the development of antiretroviral medication resistance. Results: Factors that determine class-specific adherence-resistance relationships include antiretroviral regimen potency, viral fitness or, more specifically, the interplay between the fold-change in resistance and fold-change in fitness caused by drug resistance mutations, and the genetic barrier to antiretroviral resistance. During multidrug therapy, differential drug exposure increases the likelihood of developing resistance. In addition, antiretroviral medications with higher potency and higher genetic barriers to resistance decrease the incidence of resistance for companion antiretroviral medications at all adherence levels. Conclusion: Knowledge of class-specific adherence-resistance relationships may help clinicians and patients tailor therapy to match individual patterns of adherence in order to minimize the development of resistance at failure. In addition, this information may guide the selection of optimal drug combinations and regimen sequences to improve the durability of antiretroviral therapy.

Three broad areas are reviewed related to these disparities: (1) relevant demographic, socioeconomic, and socio-cultural factors among Latinos; (2) drug abuse and mental health problems in Latinos relevant to HIV/AIDS outcomes; and (3) opportunities for psychosocial intervention. Latinos living with HIV are a rapidly growing group, are more severely impacted by HIV than whites, and confront unique challenges in coping with HIV/AIDS. A body of research suggests that depression, substance abuse, treatment adherence, health literacy, and access to healthcare may be fruitful targets for intervention research in this population. Though limited, the current literature suggests that psychosocial interventions that target these factors could help reduce HIV/AIDS disparities between Latinos and whites and could have important public health value.

Adherence was assessed using home-based pill counts and self-report. Mean adherence was over 94%. Depression was associated with incomplete adherence on multivariable analysis. Adherence declined over time. Qualitative interviews revealed lack of transportation money, stigma, clinical response to therapy, drug packaging, and cost of therapy may impact adherence. Our results indicate that providing ART to all eligible HIV-infected members in a household is associated with excellent adherence in both parents and children. Adherence to ART among new parents declines over time, even when patients receive treatment at no cost. Depression should be addressed as a potential barrier to adherence. Further study is necessary to assess the long-term impact of this family treatment model on adherence to ART in resource-limited settings.

We used cross-sectional survey data of 540 women (18-50 years) attending Mbarara University's HIV clinic in Uganda. Women were asked how much they agreed or disagreed with 23 statements about HAART. Data were subjected to a principal components and factor analyses. Subsequently, we tested the association between the scale and fertility intentions and sexual behaviour using Wilcoxon rank sum test. Factor analysis yielded three factors, one of which was an eight-item HAART optimism scale with moderately high internal consistency (alpha = 0.70). Women who reported that they intended to have (more) children had significantly higher HAART optimism scores (median = 13.5 [IQR: 12-16]) than women who did not intend to have (more) children (median = 10.5 [IQR: 8-12]; P < 0.0001). Similarly, women who were sexually active and who reported practicing unprotected sexual intercourse had significantly higher HAART optimism scores than women who were sexually abstinent or who practiced protected sexual intercourse. Our reliable and valid scale, termed the Women's HAART Optimism Monitoring and EvaluatioN scale (WHOMEN's scale), may be valuable to broader studies investigating the role of HAART optimism on reproductive intentions and sexual behaviours of HIV-positive women in high HIV prevalence settings.

We compared overall mortality stratified by HIV and smoking of 1,034 HIV-positive block-matched to 739 HIV-negative veterans, enrolled 2001-2002 in the Veterans Aging Cohort 5 Site Study. Adjusted incidence rate ratios (IRR) for mortality were calculated using Poisson regression. Mortality was significantly increased in HIV-positive veterans according to both smoking status and pack-years in unadjusted and adjusted analyses (adjusted IRR 2.31, 95% confidence interval [CI] 1.53-3.49 for HIV-positive current smokers and IRR 1.32, 95% CI 0.67-2.61 for HIV-negative current smokers). Comorbid diseases were also significantly increased according to smoking status and pack-years. Current smoking is associated with poor outcomes; even lower levels of exposure appear to be detrimental in HIV-infected veterans. These findings support the need for improvements in smoking cessation and for studies of mechanisms and diseases underlying increased mortality in smokers with HIV.

One hundred eight participants recruited between September 2006 and October 2008 completed psychodiagnostic and neuropsychological assessments and monitored HAART adherence over a 2-week period via the use of Medication Event Monitoring System (MEMS) electronic pill caps and self-report. Assessment of concurrent functioning included clinician-rated scales of depression and substance use severity, and a battery of neuropsychological tests. Findings from individual neuropsychological tests were converted to Z scores relative to standard norms and averaged to form a composite score (NPZ). NPZ was generally poor (mean = -1.505, standard deviation = 1.120), with 76.9% of the sample being classified as highly impaired. Self-reported adherence was significantly higher than MEMS cap adherence. In contrast with previous studies, overall neuropsychological functioning was not a significant predictor of electronically monitored or self-reported adherence. However, examiner-rated current global severity of substance use and delayed word list recall emerged as significant predictors of self-reported adherence. Additionally, estimated premorbid verbal intelligence emerged as a significant predictor of the discrepancy between electronically monitored and self-reported adherence. Given the extent of neuropsychological impairment in this sample, future studies should examine the degree to which the impact of neuropsychological impairment may moderate interventions for this population, and the extent to which skills to cope with neuropsychological problems may boost the potential efficacy of such interventions.

Although these registries do not have important information on long-term therapies or clinical events, administrative claims databases offer a potentially valuable complement. This article focuses on the regulatory and ethical considerations that arise from the use of registry data for research, including linkage of clinical and administrative data sets. (1) Are such activities primarily designed for quality assessment and improvement, research, or both, as this determines the appropriate ethical and regulatory standards? (2) Does the submission of data to a central registry, which may subsequently be linked to other data sources, require review by the institutional review board (IRB) of each participating organization? (3) What levels and mechanisms of IRB oversight are appropriate for the existence of a linked central data repository and the specific studies that may subsequently be developed using it? (4) Under what circumstances are waivers of informed consent and Health Insurance Portability and Accountability Act authorization required? (5) What are the requirements for a limited data set that would qualify a research activity as not involving human subjects and thus not subject to further IRB review? The approaches outlined in this article represent a local interpretation of the regulations in the context of several clinical data registry projects and focuses on a specific case study of the Society of Thoracic Surgeons National Database.

CA Get Guidelines Steering Comm Hosp TI Influence of age on the management of heart failure: Findings from Get With the Guidelines-Heart Failure (GWTG-HF) SO AMERICAN HEART JOURNAL LA English DT Article ID IMPLANTABLE CARDIOVERTER-DEFIBRILLATORS; INITIATE LIFESAVING TREATMENT; ACUTE MYOCARDIAL-INFARCTION; EARLY INVASIVE MANAGEMENT; ACUTE CORONARY SYNDROMES; QUALITY-OF-CARE; HOSPITALIZED-PATIENTS; ORGANIZED PROGRAM; OPTIMIZE-HF; PART II AB Background Heart failure (HF) is common among elderly adults. Although multiple studies demonstrate age-related declines in the utilization of evidence-based therapies for coronary artery disease, there are few analyses of HF patients to distinguish possible age-related management differences. Methods We analyzed 57,937 HF admissions from January 2005 through April 2007 in 257 hospitals participating in the American Heart Association's Get With The Guidelines-Heart Failure program. Patient characteristics and management were stratified by age groups <= 65, 66-75, 76-85, and >85 years. Multivariable regression analyses were used to assess the influence of age on use of therapies and inhospital mortality. Results The mean patient age was 73 +/- 14 years; 18.7% were >85 years of age. Prescriptions of most HF therapies were relatively reduced with age but still remained high overall. Although 88.6% of patients <= 65 years of age with left ventricular systolic dysfunction were prescribed angiotensin-converting enzyme inhibitor or angiotensin receptor blacker and 90.9% were prescribed beta-blockers, among those >85 years of age with left ventricular systolic dysfunction, 79% were prescribed angiotensin-converting enzyme inhibitor or angiotensin receptor blacker and 82.7% were prescribed beta-blockers. Regression analysis that accounted for typical confounders demonstrated that older age was associated with diminished utilization of most evidence-based treatment measures as well as increased mortality. Conclusions Get With The Guidelines-Heart Failure data demonstrate that guidelines recommended therapies are frequently utilized for older patients with HF, including patients >85 years old. Nonetheless, age-related differences in therapy persist, suggesting that opportunities to improve care still remain. (Am Heart J 2009; 157:1010-7.)

TI Cost-effectiveness of warfarin: Trial versus "real-world" stroke prevention in atrial fibrillation SO AMERICAN HEART JOURNAL LA English DT Article ID ANTITHROMBOTIC THERAPY; ISCHEMIC-STROKE; ORAL ANTICOAGULATION; CLINICAL-PRACTICE; HEART-DISEASE; RISK; METAANALYSIS; ASPIRIN; INTENSITY; PROPHYLAXIS AB Background and Purpose Previous cost-effectiveness analyses analyzed warfarin for stroke prevention in randomized trial settings. Given the complexities of warfarin treatment, cost-effectiveness should be examined within a real-world setting. Methods Our model followed patients with atrial fibrillation at moderate to high risk of stroke through primary and recurrent ischemic stroke, hemorrhages-intracranial and extracranial, and the resulting disability. Four scenarios were examined: (1) all patients start on warfarin with perfect control, that is, international normalized ratio (INR) values always within range; (2) all patients start on warfarin with trial-like control, where INR can fall outside the recommended range; (3) all patients start on warfarin with real-world INR control; and (4) real-world prescription (and control) of warfarin, aspirin, or neither for warfarin-eligible patients. Reported warfarin discontinuation rates were used. Main outcomes were total number of events, quality adjusted life years, and costs in a US setting. Results The total number of primary and recurrent ischemic strokes in a 1000-patient cohort (age 70 years, lifetime analysis) was 626, 832, 984, and 1,171 in scenarios 1 to 4, respectively. The corresponding mean quality adjusted life years per patient were 7.21, 6.92, 6.75, and 6.67 for scenarios 1 to 4, respectively. Costs per patient were $68,039, $77,764, $84,518, and $87,248 in scenarios 1 to 4, respectively. If "perfect" adherence to warfarin was assumed, except for discontinuations for clinical reasons, strokes would decrease to 503, 737, 909, and 1,120 in scenarios 1 to 4, respectively. Conclusions Clinical and cost outcomes are strongly dependent on the quality of anticoagulation and rates of warfarin discontinuation. Clinicians should work to improve both. Policy makers should use real-world INR control and warfarin discontinuation rates when assessing cost-effectiveness. (Am Heart J 2009; 157:1064-73.)

Objective: This study evaluated whether mental status screening based on this frontal-posterior axis can distinguish EODs. Methods: Twenty-three patients each with early-onset Alzheimer's disease (eAD), frontotemporal dementia (FTD), or subcortical ischemic vascular disease (SIVD), and 20 normal controls underwent the Frontal Assessment Battery (FAB) and the Perceptual Assessment Battery (PAB). Results: Compared to controls, SIVD and FTD groups were impaired on the FAB whereas eAD and SIVD groups were impaired on the PAB. The FAB/PAB ratio further differentiated the groups (F(3,85) = 26.49, P < .001). For sensitivities and specificities of 93%, a cut-off score of 1.25 on the FAB/PAB distinguished eAD, and a cut-off of 0.83 distinguishing FTD. Conclusion: Although preliminary, this study indicates that mental status screening based on frontal versus posterior cortical functions may help clinicians diagnose EODs.

Compliant patients receiving ezetimibe 10 mg were randomized in a blinded fashion to continue therapy with ezetimibe 10 mg or to convert to a split-tablet 5-mg dose. Lipid panels were collected at baseline and after 4 weeks of therapy. The impact of the 2 ezetimibe dosing strategies on LDL and the achievement of the Adult Treatment Panel III LDL goal was evaluated. One hundred thirty patients receiving ezetimibe 10 mg were screened for eligibility. Thirty-nine of the 130 patients were randomized; 36 patients successfully completed the study. All patients who had achieved their Adult Treatment Panel III LDL goals at baseline remained at their LDL goals after conversion to 5 mg. In conclusion, conversion to the lower dose of ezetimibe did not result in any clinically meaningful or statistically significant changes in any lipid parameter. (C) 2009 Published by Elsevier Inc.

TI Relation of Vigorous Exercise to Risk of Atrial Fibrillation SO AMERICAN JOURNAL OF CARDIOLOGY LA English DT Article ID LONG-DISTANCE RUNNERS; PHYSICAL-ACTIVITY; SPORT PRACTICE; FOLLOW-UP; ABLATION; ASPIRIN; TONE; MEN AB Limited data suggest that athletes may have a higher risk of developing atrial fibrillation (AF); however, there has been no large prospective assessment of the relation between vigorous exercise and AF. Logistic regression analyses stratified by time were used to assess the association between frequency of vigorous exercise and risk of developing AF in 16,921 apparently healthy men in the Physicians' Health Study. During 12 years of follow-up, 1,661 men reported developing AF. With increasing frequency of vigorous exercise (0, 1, 1 to 2, 3 to 4, 5 to 7 days/week), multivariate relative risks for the full cohort were 1.0 (referent), 0.90, 1.09, 1.04, and 1.20 (p = 0.04). This risk was not significantly increased when exercise habits were updated or in models excluding variables that may be in the biological pathway through which exercise influences AF risk. In subgroup analyses, this increased risk was observed only in men <50 years of age (1.0, 0.94, 1.20, 1.05, 1.74, p <0.01) and joggers (1.0, 0.91, 1.03, 1.30, 1.53, p <0.01), where risks remained increased in all analyses. In conclusion, frequency of vigorous exercise was associated with an increased risk of developing AF in young men and joggers. This risk decreased as the population aged and was offset by known beneficial effects of vigorous exercise on other AF risk factors. (C) 2009 Elsevier Inc.

TI Vitamin K supplementation and progression of coronary artery calcium in older men and women SO AMERICAN JOURNAL OF CLINICAL NUTRITION LA English DT Article ID MATRIX GLA PROTEIN; GAMMA-CARBOXYGLUTAMIC ACID; VASCULAR CALCIFICATION; ASYMPTOMATIC SUBJECTS; POSTMENOPAUSAL WOMEN; ATHEROSCLEROSIS MESA; COMPUTED-TOMOGRAPHY; RISK-FACTORS; WARFARIN; ATORVASTATIN AB Background: Coronary artery calcification (CAC) is an independent predictor of cardiovascular disease. A preventive role for vitamin K in CAC progression has been proposed on the basis of the properties of matrix Gla protein (MGP) as a vitamin K-dependent calcification inhibitor. Objective: The objective was to determine the effect of phylloquinone (vitamin K1) supplementation on CAC progression in older men and women. Design: CAC was measured at baseline and after 3 y of follow-up in 388 healthy men and postmenopausal women; 200 received a multivitamin with 500 mu g phylloquinone/d (treatment), and 188 received a multivitamin alone (control). Results: In an intention-to-treat analysis, there was no difference in CAC progression between the phylloquinone group and the control group; the mean (+/- SEM) changes in Agatston scores were 27 +/- 6 and 37 +/- 7, respectively. In a subgroup analysis of participants who were >= 85% adherent to supplementation (n = 367), there was less CAC progression in the phylloquinone group than in the control group (P = 0.03). Of those with preexisting CAC (Agatston score > 10), those who received phylloquinone supplements had 6% less progression than did those who received the multivitamin alone (P = 0.04). Phylloquinone-associated decreases in CAC progression were independent of changes in serum MGP. MGP carboxylation status was not determined. Conclusions: Phylloquinone supplementation slows the progression of CAC in healthy older adults with preexisting CAC, independent of its effect on total MGP concentrations. Because our data are hypothesis-generating, further studies are warranted to clarify this mechanism. This trial was registered at clinicaltrials. gov as NCT00183001.

TI The Effect of Argatroban on Activated Protein C Resistance SO AMERICAN JOURNAL OF CLINICAL PATHOLOGY LA English DT Article DE Argatroban; Anticoagulation; Activated protein C resistance; Interference ID FACTOR-V-LEIDEN; LUPUS ANTICOAGULANTS; THROMBOSIS; THERAPY; RISK AB Activated protein C (APC) resistance is commonly tested in hypercoagulation evaluations, and argatroban is an anticoagulant therapy used in hypercoagulable patients. The effect of argatroban on APC resistance testing is unknown. We studied 100 ex vivo specimens from 44 patients treated with argatroban. Argatroban increased the APC resistance ratio in all but 1 patient. The effect was seen even in the specimens containing subtherapeutic argatroban levels. For patients without APC resistance, the mean APC resistance ratio significantly increased from 2.43 without argatroban to 3.10 with argatroban. For patients with APC resistance due to factor V Leiden, argatroban significantly increased the mean ratio from 1.73 to 2.13, falsely raising it into the normal range (> 2). Argatroban increases the APC resistance ratio, which can mask a diagnosis of APC resistance and, therefore, factor V Leiden. Clinicians should be advised that APC resistance testing for patients receiving argatroban is not valid. C1 [Van Cott, Elizabeth M.] Massachusetts Gen Hosp, Dept Pathol, Boston, MA 02114 USA.

Methods: Streptococcus mutans was used to develop a biofilm that adhered to the surfaces of the selected material disks in 30 days. The specimens were stained and analyzed by confocal laser scanning microscopy and COMSTAT. Among biofilm properties, mean thickness, total bio-volume, roughness coefficient and surface-to-volume ratio were investigated, as well as characteristics of the distribution and architecture of viable/nonviable cells in the biofilm. Results: Only the mean biofilm thickness was statistically significantly different among the restorative materials tested. C and RC accumulated the thickest biofilms. Qualitative analysis showed cellular aggregates and fluid-filled channels penetrating to a considerable depth of the biofilm. In addition, images demonstrated a progression of more viable cells in superficial regions of the biofilm to proportionally more nonviable cells in the deeper regions of the biofilms near the disk.

TI Antibiotic prescribing for presumed nonbacterial acute respiratory tract infections SO AMERICAN JOURNAL OF EMERGENCY MEDICINE LA English DT Article CT National Annual Meeting of the US-Department-of-Veterans-Affairs-Health-Services-Research-and-Developme nt-Service CY FEB, 2005 CL Baltimore, MD SP US Dept Vet Affairs Hlth Serv Res & Dev Serv ID ACUTE BRONCHITIS; STREPTOCOCCUS-PNEUMONIAE; EMERGENCY-DEPARTMENTS; AMBULATORY PRACTICE; CARE PHYSICIANS; UNITED-STATES; ADULTS; TRENDS; PREDICTORS; MANAGEMENT AB Objective: The objective of the study was to identify patient and provider factors associated with prescribing antibiotics for outpatients with acute respiratory tract infections of likely nonbacterial etiology. Methods: We identified outpatients who were diagnosed in the emergency department with nonspecific upper respiratory tract infections (URIs) and acute bronchitis at the VA Pittsburgh Healthcare System from June 15, 2003, to June 14, 2004, and the Philadelphia VA Medical Center from November 30, 2003, to March 31, 2004. Stepwise logistic regression was used to identify factors independently associated with antibiotic prescribing. Results: Overall, 26% of the 667 eligible patients with URIs and/or acute bronchitis received antibiotics. Antibiotics were prescribed significantly more frequently for acute bronchitis at one site (97% vs 65%, P < .001). Using multivariable analysis, the following factors were independently associated with antibiotic prescribing (odds ratio, 95% confidence interval): presence of I or more comorbidities (2.1, 1.2-3.5), fever (2.5, 1.4-4.4), purulent sputum (2.5, 1.5-4.4), shortness of breath (2.8, 1.4-5.4), altered breath sounds (4.6, 2.4-8.6), diagnosis of acute bronchitis (15.9, 8.0-31.8), provider age >= 30 years (2.6, 1.1-6.3), and noninternal medicine specialty (2.7, 1.2-6.0). Conclusions: Antibiotic use was high and varied substantially for URN and acute bronchitis. Specific signs and symptoms, a diagnosis of acute bronchitis, and provider age and specialty were associated with antibiotic prescribing. Interventions to decrease inappropriate prescribing should address the perceived utility of antibiotics in acute bronchitis and the accuracy of signs and symptoms in diagnosing a bacterial respiratory infection.

We examined social support levels among a diverse population of adults seeking ED care for acute respiratory tract infections. A convenience sample of adults seeking care in I of 15 US EDs was telephone interviewed 1 to 6 weeks postvisit. The Multidimensional Scale of Perceived Social Support (7-point Likert) assessed social support across 3 domains: friends, family, and significant others. Higher scores indicate higher support. Of 1104 subjects enrolled, 704 (64%) completed the follow-up interview. Factor analysis yielded 3 factors. Mean social support score was 5.54 (SD 1.04). Female sex, greater household income, and better health status were independently associated with higher levels of social support. Social support levels among adults seeking care in the ED for acute respiratory tract infections are similar to general population cohorts, suggesting that social support is not a strong determinant of health care seeking in EDs.

TI Invited Commentary: Lower Urinary Tract Symptoms and Inflammation - Weighing the Evidence SO AMERICAN JOURNAL OF EPIDEMIOLOGY LA English DT Editorial Material DE inflammation; prostate; urinary tract physiological phenomena ID MEN AB Lower urinary tract symptoms (LUTS) are a common condition, particularly among older men. The etiology of these symptoms is often obscure and not always clearly related to prostatic enlargement or benign prostatic hyperplasia. St. Sauver et al. (Am J Epidemiol. 2009;169(11):1281-1290) hypothesized that systemic inflammation may be associated with LUTS and benign prostatic hyperplasia. Using a well-defined cohort, they found that, in general, inflammation was not related to LUTS or to benign prostatic hyperplasia progression. However, men with the highest amount of systemic inflammation, as measured by C-reactive protein levels, were at increased risk of a rapid change in irritative voiding symptoms and decreased urinary flow but not obstructive voiding symptoms or prostate size. To what degree systemic inflammation relates to inflammation within the urinary system and specifically the bladder and/or prostate is unclear. Furthermore, to what degree inflammation within the urinary system contributes to LUTS is unclear. Given that clinical trials of antiinflammatory drugs for LUTS have been largely unsuccessful, the role of inflammation as a contributor to LUTS remains an interesting hypothesis that requires further study.

METHODS: We modified the traditional West Haven criteria (WHC) to provide an objective assessment of the cognitive parameters to complement the subjective clinical ratings for the performance of extracorporeal albumin dialysis (ECAD) using a molecular adsorption recirculating system in patients with cirrhosis and severe (grade III/IV) encephalopathy. The HE Scoring Algorithm (HESA) combined clinical indicators with those derived from simple neuropsychological tests, the latter more often used in milder grades of HE (I/II). The performance of each indicator was compared across grades and sites. RESULTS: Results of HESA were also compared with the Glasgow Coma Scale. A total of 597 evaluations were performed in patients randomized to ECAD plus standard medical therapy or the latter only. Most parameters exhibited significant separation between grades; the most effective indicators were lack of verbal, eye, and motor response (grade IV), somnolence and disorientation to place (grade III), and lethargy and disorientation to time (grade II). Two clinical and four neuropsychological indicators were useful to classify patients as grade I. The Glasgow Coma Scale differed among the four stages of the WHC, but the differences between grades I and II were small and not clinically useful. CONCLUSION: HESA extends the traditional WHC for grading HE. In the absence of a "gold" standard, the most useful indicators noted in this trial should be further validated.

TI The Utility of Evaluating Low Serum Albumin Gradient Ascites in Patients With Cirrhosis SO AMERICAN JOURNAL OF GASTROENTEROLOGY LA English DT Article ID PERITONITIS; DIAGNOSIS; PROTEIN; FLUID AB OBJECTIVES: Serum-ascites albumin gradient (SAAG) has been used extensively in the diagnostic workup of patients with ascites. A SAAG level of <1.1 g/dl is usually thought of as a result of nonportal hypertension etiologies, including malignancies, tuberculous peritonitis, and nephrotic syndrome. However, the predictive value of a low SAAG in patients with existing cirrhosis in whom the pretest probability of portal hypertension is high is not clear. METHODS: We identified all patients with a SAAG of <1.1 g/dl during a 5-year period at a single large veterans affairs medical center. Cirrhosis was defined by clinical, histological, and radiological features. Nonportal hypertension causes of low SAAG were identified, including bacterial peritonitis, peritoneal carcinomatosis, nephrogenous ascites, tuberculous peritonitis, chylous ascites, and pancreatic ascites. RESULTS: We identified 92 patients (76 with cirrhosis and 16 with no cirrhosis) with ascites and a SAAG of <1.1 g/dl. Of the 76 patients with cirrhosis, only 29 (38%) had an identifiable cause, most commonly primary bacterial peritonitis (11, 38%), followed by peritoneal carcinomatosis or malignant ascites (8, 28%) and nephrotic syndrome (5, 17%). There were 47 patients with cirrhosis and a low SAAG for whom no etiology was identified. Thirty-three patients underwent a repeat paracentesis, 24 (73%) of whom changed to a high SAAG. On the other hand, the 16 patients with no cirrhosis had significantly lower SAAG (0.66 vs. 0.81), and most (12, 75 %) had an identifiable cause of ascites. CONCLUSIONS: Evaluation of a SAAG <1.1 g/dl in patients with known cirrhosis has low yield and is less likely to be helpful than that in patients without cirrhosis. A repeat paracentesis as part of the workup is recommended. Further studies of low SAAG cutoffs are needed.

TI A Treatment Trial of Acupuncture in IBS Patients SO AMERICAN JOURNAL OF GASTROENTEROLOGY LA English DT Article ID IRRITABLE-BOWEL-SYNDROME; RANDOMIZED CONTROLLED-TRIAL; QUALITY-OF-LIFE; PLACEBO RUN-IN; LOW-BACK-PAIN; CLINICAL-TRIALS; ALTERNATIVE MEDICINE; DIARRHEA-PREDOMINANT; END-POINT; ADEQUATE RELIEF AB OBJECTIVES: This study aimed to compare the effects of true and sham acupuncture in relieving symptoms of irritable bowel syndrome (IBS). METHODS: A total of 230 adult IBS patients (75% females, average age: 38.4 years) were randomly assigned to 3 weeks of true or sham acupuncture (6 treatments) after a 3-week "run-in" with sham acupuncture in an "augmented" or "limited" patient-practitioner interaction. A third arm of the study included a waitlist control group. The primary outcome was the IBS Global Improvement Scale (IBS-GIS) (range: 1-7); secondary outcomes included the IBS Symptom Severity Scale (IBS-SSS), the IBS Adequate Relief (IBS-AR), and the IBS Quality of Life (IBS-QOL). RESULTS: Although there was no statistically significant difference between acupuncture and sham acupuncture on the IBS-GIS (41 vs. 32%, P=0.25), both groups improved significantly compared with the waitlist control group (37 vs. 4%, P=0.001). Similarly, small differences that were not statistically significant favored acupuncture over the other three outcomes: IBS-AR (59 vs. 57%, P=0.83), IBS-SSS (31 vs. 21%, P=0.18), and IBS-QOL (17 vs. 13%, P=0.56). Eliminating responders during the run-in period did not substantively change the results. Side effects were generally mild and only slightly greater in the acupuncture group. CONCLUSIONS: This study did not find evidence to support the superiority of acupuncture compared with sham acupuncture in the treatment of IBS.

"Open-access" colonoscopy makes it challenging to identify who needs genetic evaluation, intensive surveillance, and screening for extracolonic tumors. Our aim was to develop a simple, preprocedural risk assessment tool to identify who may be at highest risk for CRC. METHODS: A total of 631 outpatients undergoing colonoscopy at two academic practices completed a questionnaire assessing personal and family histories of CRC, polyps, and Lynch syndrome (LS)-associated malignancies. Subjects were considered to be high-risk if one of the nine prespecified characteristics of hereditary CRC syndromes was met. Through recursive partitioning analysis, an algorithm of fewest questions needed to capture the most high-risk individuals was developed. The results were validated in 5,335 individuals undergoing colonoscopy at five private endoscopy centers and tested in 285 carriers of mismatch repair mutations associated with LS. RESULTS: About 17.7% and 20.0% of individuals were classified as high-risk in the development and validation cohorts, respectively. Recursive partitioning revealed three questions that were most informative for identifying high-risk patients: (i) "Do you have a first-degree relative with CRC or LS-related cancer diagnosed before age 50?" (ii) "Have you had CRC or polyps diagnosed before age 50?" (iii) "Do you have >= 3 relatives with CRC?" When asked successively, these questions identified 77% of high-risk individuals in both cohorts and 271 of 285 (95%) of mutation carriers. CONCLUSIONS: Approximately one in five individuals undergoing colonoscopy would benefit from further risk assessment. We developed a simple, three-question CRC Risk Assessment Tool to identify the majority of patients who require additional assessment and possible genetic evaluation.

TI Results of a Longitudinal Analysis of National Data to Examine Relationships Between Organizational and Market Characteristics and Changes in Antipsychotic Prescribing in US Nursing Homes From 1996 Through 2006 SO AMERICAN JOURNAL OF GERIATRIC PHARMACOTHERAPY LA English DT Article DE aged; antipsychotics; elderly; nursing homes; prescribing patterns ID QUALITY-OF-CARE; RANDOMIZED-TRIAL; DRUG-USE; DEMENTIA; RESIDENTS; PLACEBO; RISK; REGULATIONS; MEDICATIONS; RISPERIDONE AB Objective: The aim of this work was to examine the association between organizational characteristics, market characteristics, and changes in antipsychotic medication use in US nursing homes over time. Methods: This was a longitudinal study comparing antipsychotic use in US nursing homes from 1996 through 2006 using Medicare and Medicaid data (the Online Survey Certification And Reporting system) and US Department of Health and Human Resources Health Resources and Services Administration data (the Area Resource File). The 3 outcomes of interest were increasing, decreasing, or stable use of antipsychotic medications. The primary independent variables were organizational characteristics (eg, for-profit status, chain membership) and market characteristics (eg, Medicaid reimbursement, levels of competition). Results: Antipsychotic use increased from 16.4% in 1996 to 25.9% in 2006 (P < 0.05). A multinomial generalized estimating equations model, controlling for facility, staffing, and resident factors, suggested that increased antipsychotic use was associated with for-profit facilities (adjusted odds ratio [AOR], 1.58; 95% CI, 1.51-1.65; P <= 0.001). Decreased antipsychotic use was associated with chain membership (AOR, 0.82; 95% CI, 0.79-0.85; P <= 0.001), higher levels of competition (AOR, 1.22; 95% CI, 1.16-1.29; P <= 0.001), and a higher Medicaid reimbursement rate (AOR, 0.88; 95% CI, 0.85-0.92; P <= 0.001). Conclusions: Antipsychotic use increased in US nursing homes from 1996 through 2006 and was associated with certain organizational characteristics and market characteristics. Future interventions to reduce antipsychotic use in nursing homes will have to focus Oil these factors. (Am J Geriatr Pharmacother. 2009;7:143-150) (C) 2009 Excerpta Medica Inc.

TI The Aging Physician With Cognitive Impairment: Approaches to Oversight, Prevention, and Remediation SO AMERICAN JOURNAL OF GERIATRIC PSYCHIATRY LA English DT Article DE Aging; physician; dementia; dyscompetence; impairment AB There are many important unanswered issues regarding the occurrence of cognitive impairment in physicians, such as detection of deficits, remediation efforts, policy implications for safe medical practice, and the need to safeguard quality patient care. The authors review existing literature on these complex issues and derive heuristic formulations regarding how to help manage the professional needs of the aging physician with dementia. To ensure safe standards of medical care while also protecting the needs of physicians and their families, state regulatory or licensing agencies in collaboration with state medical associations and academic medical centers should generate evaluation guidelines to assure continued high levels of functioning. The authors also raise the question of whether age should be considered as a risk factor that merits special screening for adequate functioning. Either age-related screening for cognitive impairment should be initiated or rigorous evaluation after lapses in standard of care should be the norm regardless of age. Ultimately, competence rather than mandatory retirement due to age per se should be the deciding factor regarding whether physicians should be able to continue their practice. Finally, the authors issue a call for an expert consensus panel to convene to make recommendations concerning aging physicians with cognitive impairment who are at risk for medical errors.

Design: Randomized, controlled pilot study. Setting: University-based geriatric medicine clinics. Participants: Thirty-one elderly primary care patients with generalized anxiety disorder or anxiety disorder not otherwise specified. Intervention: Modular form of psychotherapy compared with enhanced community treatment. Measurements: Self-reported, interviewer-rated, and qualitative assessments of anxiety, worry, depression, and mental health-related quality of life. Results: Both groups showed substantial improvements in anxiety symptoms, worry, depressive symptoms, and mental health-related quality of life. Most individuals in the enhanced community treatment condition reported receiving medications or some other form of professional treatment for anxiety. Across both conditions, individuals who reported major life events or stressors and those who used involvement in activities as a coping strategy made smaller gains than those who did not. Conclusions: Results suggest that modular psychotherapy and other treatments can be effective for anxiety in older primary care patients. Results further suggest that life events and coping through increased activity may play a role in the maintenance of anxiety in older adults.

The impact of AKI on long-term outcomes is controversial. Study Design: Systematic review and meta-analysis. Setting & Participants: Persons with AKI. Selection Criteria for Studies: MEDLINE and EMBASE databases were searched from 1985 through October 2007. Original studies describing outcomes of AKI for patients who survived hospital discharge were included. Studies were excluded from review when participants were followed up for less than 6 months. Predictor: AKI, defined as acute changes in serum creatinine level or acute need for renal replacement therapy. Outcomes: Chronic kidney disease (CKD), cardiovascular disease, and mortality. Results: 48 studies that contained a total of 47,017 participants were reviewed; 15 studies reported long-term data for patients without AKI. The incidence rate of mortality was 8.9 deaths/100 person-years in survivors of AKI and 4.3 deaths/100 patient-years in survivors without AKI (rate ratio [RR], 2.59; 95% confidence interval, 1.97 to 3.42). AKI was associated independently with mortality risk in 6 of 6 studies that performed multivariate adjustment (adjusted RR, 1.6 to 3.9) and with myocardial infarction in 2 of 2 studies (RR, 2.05; 95% confidence interval, 1.61 to 2.61). The incidence rate of CKD after an episode of AKI was 7.8 events/100 patient-years, and the rate of end-stage renal disease was 4.9 events/100 patient-years. Limitations: The relative risk for CKD and end-stage renal disease after AKI was unattainable because of lack of follow-up of appropriate controls without AKI. Conclusions: The development of AKI, defined as acute changes in serum creatinine level, characterizes hospitalized patients at increased risk of long-term adverse outcomes.

TI Reviewing the Evidence for Mycophenolate Mofetil as a New Teratogen: Case Report and Review of the Literature SO AMERICAN JOURNAL OF MEDICAL GENETICS PART A LA English DT Article DE CellCept (R); cleft lip and palate; coloboma; malformation; microtia; mycophenolate mofetil; teratogenesis ID ACROFACIAL DYSOSTOSIS; PREGNANCY; EXPOSURE; IMMUNOSUPPRESSION; TRANSPLANTATION; MALFORMATIONS; EMBRYOPATHY; RECIPIENTS; OUTCOMES; EDITORS AB Mycophenolate mofetil (MMF) (CellCept (R)) is an immunosuppressant drug that is teratogenic in rats and rabbits. Reports of malformations in 13 offspring of women exposed to MMF in pregnancy raise concern that MMF is also a human teratogen. We report an additional child with malformations following prenatal exposure to MMF and review the other 13 reports. We identified a Cambodian male born at 31 weeks' gestation to a mother who had been treated for lupus nephritis with MMF from before conception to 12 weeks' gestational age. He had bilateral moderate-to-severe microtia, external auditory canal atresia, bilateral conductive hearing loss, mild microcephaly, and apparently normal development. Among the 14 MMF-exposed offspring now reported, the underlying maternal conditions were kidney transplantation (7), lupus nephritis (4), liver transplantation (1), heart transplantation (1), and recurrent erythema. multiforme (1). All were exposed in early pregnancy. The most distinctive malformation was moderate-to-severe microtia. or anotia (12), with external auditory canal atresia in 9. Other common craniofacial malformations and minor anomalies included orofacial clefts (7), hypertelorism (3), coloboma (3), and micrognathia (3). Six had cardiovascular malformations, of which three were either conotruncal or aortic arch defects. MMF dose, reported in 12 patients, was <1 g/day in 4 and 1 g or more/day in 8; no correlation between dose and phenotype severity was apparent. While case reports have limited value in identifying human teratogens, the unusual distribution of malformations among the 14 reported exposed offspring identifies a phenotype suggesting that MMF is likely a human teratogen.

The prevalence and clinical significance of these findings have not been well described. METHODS: Consecutive patients presenting to the emergency department with acute chest pain and inconclusive initial evaluation between May 2005 and May 2007 underwent 64-slice coronary computed tomography angiography before hospital admission with noncoronary incidental findings immediately reported. An expert panel adjudicated which incidental findings changed in-hospital patient management, and projections for additional testing were based on standard medical practice. RESULTS: Among 395 patients (37.0% were female, mean age 53 +/- 12 years), incidental findings were detected in 44.8% (n = 177): noncalcified pulmonary nodules (n = 94, 23.8%), simple liver cysts (n = 26, 6.6%), calcified pulmonary nodules (n = 16, 4.1%), and contrast-enhancing liver lesions (n = 9, 2.3%). In-hospital management was changed because of incidental finding reporting in 5 patients (1.3%), and a potential alternative diagnosis was offered in another 16 patients (4.1%). Subsequent diagnostic imaging tests were recommended in 81 patients (20.5%), including 74 chest computed tomography scans. After 6 months, biopsy was performed in 3 patients, revealing cancer in 2 (0.5%) who underwent successful tumor resection. CONCLUSION: Clinically important findings are detected in up to 5% of patients with a lead symptom of acute chest pain and low to intermediate likelihood of acute coronary syndrome, but only few directly change patient management; 21% are recommended for further imaging tests, resulting in invasive procedures and detection of cancer in few patients.

TI Predicting Success and Long-Term Outcomes of Percutaneous Mitral Valvuloplasty: A Multifactorial Score SO AMERICAN JOURNAL OF MEDICINE LA English DT Article DE Percutaneous mitral valvuloplasty; Prognosis; Score ID BALLOON VALVOTOMY; FOLLOW-UP; COMMISSUROTOMY; IMMEDIATE; STENOSIS; DISEASE; COMPLICATIONS; DILATATION; VARIABLES; VALVE AB BACKGROUND: Percutaneous mitral valvuloplasty (PMV) success depends on appropriate patient selection. A multifactorial score derived from clinical, anatomic/echocardiographic, and hemodynamic variables would predict procedural success and clinical outcome. METHODS: Demographic data, echocardiographic parameters (including echocardiographic score), and procedure-related variables were recorded in 1085 consecutive PMVs. Long-term clinical follow-up (death, mitral valve replacement, redo PMV) was performed. Multivariate regression analysis of the first 800 procedures was performed to identify independent predictors of procedural success. Significant variables were formulated into a risk score and validated prospectively. RESULTS: Six independent predictors of PMV success were identified: age less than 55 years, New York Heart Association classes I and II, pre-PMV mitral area of 1 cm(2) or greater, pre-PMV mitral regurgitation grade less than 2, echocardiographic score of 8 or greater, and male sex. A score was constructed from the arithmetic sum of variables present per patient. Procedural success rates increased incrementally with increasing score (0% for 0/6, 39.7% for 1/6, 54.4% for 2/6, 77.3% for 3/6, 85.7% for 4/6, 95% for 5/6, and 100% for 6/6; P < .001). In a validation cohort (n = 285 procedures), the multifactorial score remained a significant predictor of PMV success (P < .001). Comparison between the new score and the echocardiographic score confirmed that the new index was more sensitive and specific (P < .001). This new score also predicts long-term outcomes (P < .001). CONCLUSION: Clinical, anatomic, and hemodynamic variables predict PMV success and clinical outcome and may be formulated in a scoring system that would help to identify the best candidates for PMV.

TI Comprehensive Meta-Analysis on Drug-Eluting Stents versus Bare-Metal Stents during Extended Follow-up SO AMERICAN JOURNAL OF MEDICINE LA English DT Article DE Bare-metal stent; Drug-eluting stent; Percutaneous coronary intervention; Stent thrombosis ID ACUTE MYOCARDIAL-INFARCTION; RANDOMIZED CLINICAL-TRIALS; CORONARY-ARTERY LESIONS; DOUBLE-BLIND TRIAL; DIABETIC-PATIENTS; UNCOATED STENTS; STANDARD STENT; SLOW-RELEASE; CANADIAN MULTICENTER; LATE THROMBOSIS AB BACKGROUND: Several observational reports have documented both increased and decreased cardiac mortality or Q-wave myocardial infarction with drug-eluting stents compared with bare-metal stents. METHODS: We sought to evaluate the safety and efficacy of drug-eluting stents compared with bare-metal stents early after intervention (<1 year) and late (>1 year) among a broad population of patients, using a meta-analysis of randomized clinical trials. RESULTS: We identified 28 trials with a total of 10,727 patients and a mean follow-up of 29.6 months. For early outcomes (<1 year), all-cause mortality for drug-eluting stents versus bare-metal stents was 2.1% versus 2.4% (risk ratio [RR] 0.91, [95% confidence interval (CI), 0.70-1.18]; P = .47), non-Q-wave myocardial infarction was 3.3% versus 4.4% (RR 0.78 [95% CI, 0.61-1.00]; P = .055), target lesion revascularization was 5.8% versus 18.4% (RR 0.28 [95% CI, 0.21-0.38]; P = .001), and stent thrombosis was 1.1% versus 1.3% (RR 0.87 [95% CI, 0.60-1.26]; P = .47). For late outcomes (>1 year), all-cause mortality for drug-eluting stents versus bare-metal stents was 5.9% versus 5.7% (RR 1.03 [95% CI, 0.83-1.28]; P = .79), target lesion revascularization was 4.0% versus 3.3% (RR 1.22 [95% CI, 0.92-1.60]; P = .16), non-Q-wave myocardial infarction was 1.6% versus 1.2% (RR 1.36 [95% CI, 0.74-2.53]; P = .32) and stent thrombosis was 0.7% versus 0.1% (RR 4.57 [95% CI, 1.54-13.57]; P = .006). CONCLUSIONS: There was no excess mortality with drug-eluting stents. Within 1 year, drug-eluting stents appear to be safe and efficacious with possibly decreased non-Q-wave myocardial infarction compared with bare-metal stents. After 1 year, drug-eluting stents still have similar mortality, despite increased stent thrombosis. The reduction in target lesion revascularization with drug-eluting stents mainly happens within 1 year, but is sustained thereafter. Published by Elsevier Inc.

TI Diagnostic Accuracy and Yield of Multidetector CT Angiography in the Evaluation of Spontaneous Intraparenchymal Cerebral Hemorrhage SO AMERICAN JOURNAL OF NEURORADIOLOGY LA English DT Article; Proceedings Paper CT 45th Annual Meeting of the American-Society-of-Neuroradiology CY JUN 09-11, 2007 CL Chicago, IL SP Amer Soc Neuroradiol ID INTRACEREBRAL HEMORRHAGE; ARTERIOVENOUS-MALFORMATIONS; AMYLOID ANGIOPATHY; RISK-FACTORS; INTRACRANIAL HEMORRHAGE; COMPUTED-TOMOGRAPHY; NATURAL-HISTORY; ANEURYSMS; BRAIN; HEMATOMA AB BACKGROUND AND PURPOSE: Multidetector CT angiography (MDCTA) is emerging as the favored initial diagnostic examination in the evaluation of patients presenting with spontaneous intraparenchymal hemorrhage (IPH). This study aims to evaluate the diagnostic accuracy and yield of MDCTA for the detection of vascular etiologies in adult patients presenting to the emergency department with IPH. MATERIALS AND METHODS: We conducted a retrospective study of 623 consecutive adult patients presenting to the emergency department with IPH, who were evaluated with MDCTA during a 9-year period. CT angiograms were reviewed by 2 neuroradiologists to determine the IPH site and the presence of a vascular etiology. Patients with associated subarachnoid hemorrhage in the basal cisterns were excluded from the study. Medical records were reviewed for risk factors and correlation with final diagnosis. The diagnostic accuracy of MDCTA compared with conventional angiography, intraoperative evaluation, and pathologic findings was determined, when available. Multiple-variable logistic regression analysis was performed to determine clinical and radiologic factors that predict a higher yield of MDCTA. RESULTS: MDCTA demonstrated a vascular etiology in 91 patients (14.6%), with a sensitivity of 96%, specificity of 99%, and diagnostic accuracy of 98%. We found independent, statistically significant higher yields of MDCTA in patients with the following characteristics: 1) age younger than 46 years (47%); 2) lobar (20%) or infratentorial (16%) IPH, especially lobar IPH with associated intraventricular hemorrhage (25%); 3) female sex (18%); or 4) neither known hypertension nor impaired coagulation at presentation (33%). CONCLUSIONS: MDCTA is an accurate diagnostic examination in the evaluation of adult patients presenting with spontaneous IPH and should be performed in all patients with the aforementioned clinical and radiologic characteristics.

Cortical porosity is the result of osteoclast activity; however, the etiology of marrow fibrosis is poorly understood. While osteoclast numbers and activity are regulated by osteoprotegerin (OPG), bisphosphonates suppress osteoclast activity but not osteoclast numbers. We therefore used OPG and bisphosphonates to evaluate the extent to which osteoclasts, as opposed to bone resorption, regulate marrow fibrosis in PPR*Tg mice after treatment of animals with vehicle, OPG, alendronate, or zoledronate. All three agents similarly increased trabecular bone volume in both PPR*Tg and control mice, suggesting that trabecular bone resorption was comparably suppressed by these agents. However, the number of trabecular osteoclasts was greatly decreased by OPG but not by either alendronate or zoledronate. Furthermore, intracortical porosity and marrow fibrosis were virtually abolished by OPG treatment, whereas alendronate and zoledronate only partially reduced these two parameters. The greater reductions in cortical porosity and increments in cortical bone mineral density with OPG in PPR*Tg mice were associated with greater improvements in bone strength. The differential effect of OPG versus bisphosphonates on marrow fibrosis, despite similar effects on trabecular bone volume, suggests that marrow fibrosis was related not only to bone resorption but also to the presence of osteoclasts.

TI Oxidative Stress and Compartment of Gene Expression Determine Proatherosclerotic Effects of Inducible Nitric Oxide Synthase SO AMERICAN JOURNAL OF PATHOLOGY LA English DT Article ID VASCULAR SMOOTH-MUSCLE; E-DEFICIENT MICE; DIET-INDUCED ATHEROSCLEROSIS; TRAUMATIC BRAIN-INJURY; E-KNOCKOUT MICE; IN-VIVO; SUPEROXIDE GENERATION; NO-SYNTHASE; TETRAHYDROBIOPTERIN; 17-BETA-ESTRADIOL AB Genetic and pharmacological inhibition of inducible nitric oxide synthase (iNOS) decreases atherosclerosis development. Potential proatherogenic effects of iNOS include iNOS mediated oxidative stress and iNOS expression in different cellular compartments. Lesional iNOS can potentially produce nitric oxide radicals (NO), superoxide radicals (O(2)(-)), or both; these radicals may then react to form peroxynitrite. Alternatively, O(2)(-) radicals from oxidases co-expressed with iNOS could react with NO to produce peroxynitrite. Therefore, the expression profiles of the genes that modulate the redox system in different iNOS-expressing cell compartments may determine the role of iNOS in atherosclerosis. We used apoE (apoE(-/-)) and apoE/iNOS double knockout (apoE(-/-)/iNOS(-/-)) mice to assess vascular NO, O(2)(-), and peroxynitrite formation by electron spin resonance spectroscopy, high performance liquid chromatography, and 3-nitrotyrosine staining. The relevance of the iNOS expressing cell compartment was tested by bone marrow transplantation. We show that iNOS significantly contributes to vascular NO production and itself produces O(2)(-), leading to peroxynitrite formation in atherosclerotic lesions. Our bone marrow transplantation experiments show that bone marrow derived cells exclusively mediate the proatherosclerotic effects of iNOS in mates, while both parenchymal and bone marrow derived iNOS equally contribute to atherosclerosis in females. Moreover, iNOS expression affects vascular remodeling. These findings establish for the first time that the proatherosclerotic effects of iNOS vary with sex in addition to the compartment of its expression.

Vasopressin-induced differential stimulation of AQP4 splice variants regulates the in-membrane assembly of orthogonal arrays. Am J Physiol Renal Physiol 296: F1396-F1404, 2009. First published March 18, 2009; doi: 10.1152/ajprenal.00018.2009.-Aquaporin-4 (AQP4) is a basolateral water channel in collecting duct principal cells and assembles into orthogonal array particles (OAPs), the size of which appears to depend on relative expression levels of AQP4 splice variants. Because the higher-order organization of AQP4 was perturbed by vasopressin in Brattleboro rats and phosphorylation sites have been identified on AQP4, we investigated whether vasopressin and forskolin (Fk) affect AQP4 assembly and/or expression in LLC-PK1 cells stably transfected with the AQP4 splice variant M23, which is responsible for formation of OAPs, and/or the splice variant M1, which does not form OAPs. Our data show that [lys(8)]-vasopressin (LVP) and Fk treatment led to differential increases in expression levels of M23-AQP4 and M1-AQP4 that varied as a function of incubation time. At early time points (day 1) expression of M1 was significantly stimulated (4.5-fold), over that of M23 (1.6-fold), but after 3 days the expression of M23 became predominant (4.1-fold) over that of M1 (1.9-fold). This pattern of stimulation was dependent on an intact AQP4 residue serine 111 and required protein synthesis. In cells expressing both M1 and M23 (M1/M23 similar to 1), with small sized OAPs at the membrane, the LVP/Fk-induced stimulation of M23 was modified and mimicked that of M1 when expressed alone, suggesting a dominant role for M1. In Brattleboro kidney inner medulla, an 8-day chronic exposure to the vasopressin agonist (dDAVP) led to reduction in M1 and a significant increase in M23 immunoblot staining (M1/M23 = 2/3 -> 1/4). These results indicate that AQP4 organization and expression are regulated by vasopressin in vivo and in vitro and demonstrate that the dominant role for M1 is restricted to a one-to-one interaction between AQP4 splice variants that regulates the membrane expression of OAPs.

TI Prenatal Exposure to Maternal Infection and Executive Dysfunction in Adult Schizophrenia SO AMERICAN JOURNAL OF PSYCHIATRY LA English DT Article; Proceedings Paper CT 62nd Annual Meeting of the Society-of-Biological-Psychiatry CY MAY 17-20, 2007 CL San Diego, CA SP Soc Biol Psychiat ID OBSTETRIC COMPLICATIONS; RISK; DEFICITS; PERFORMANCE; TOXOPLASMOSIS; DETERMINANTS; INFLUENZA; PATTERNS; SIBLINGS AB Objective: Executive dysfunction is one of the most prominent and functionally important cognitive deficits in schizophrenia. Although strong associations have been identified between executive impairments and structural and functional prefrontal cortical deficits, the etiological factors that contribute to disruption of this important cognitive domain remain unclear. Increasing evidence suggests that schizophrenia has a neurodevelopmental etiology, and several prenatal infections have been associated with risk of this disorder. The authors examined whether prenatal infection is associated with executive dysfunction in patients with schizophrenia. Method: The authors assessed the relationship between serologically documented prenatal exposure to influenza and toxoplasmosis and performance on the Wisconsin Card Sorting Test and the Trail Making Test, part B (Trails B), as well as other measures of executive function, in 26 patients with schizophrenia from a large and well-characterized birth cohort. Results: Patients who were exposed to infection in utero committed significantly more total errors on the Wisconsin Card Sorting Test and took significantly more time to complete the Trails B than unexposed patients. Exposed patients also exhibited deficits on figural fluency, letter-number sequencing, and backward digit span. Conclusions: Prenatal infections previously associated with schizophrenia are related to impaired performance on the Wisconsin Card Sorting Test and Trails B. The pattern of results suggests that cognitive set-shifting ability may be particularly vulnerable to this gestational exposure. Further work is needed to elucidate the specificity of prenatal infection to these executive function measures and to examine correlates with neuroanatomic and neurophysiologic anomalies.

However, few neuroimaging studies of depression have distinguished between anticipatory and consummatory phases of reward processing. Using functional MRI (fMRI) and a task that dissociates anticipatory and consummatory phases of reward processing, the authors tested the hypothesis that individuals with major depression would show reduced reward-related responses in basal ganglia structures. Method: A monetary incentive delay task was presented to 30 unmedicated individuals with major depressive disorder and 31 healthy comparison subjects during fMRI scanning. Whole-brain analyses focused on neural responses to reward-predicting cues and rewarding outcomes (i.e., monetary gains). Secondary analyses focused on the relationship between anhedonic symptoms and basal ganglia volumes. Results: Relative to comparison subjects, participants with major depression showed significantly weaker responses to gains in the left nucleus accumbens and the caudate bilaterally. Group differences in these regions were specific to rewarding outcomes and did not generalize to neutral or negative outcomes, although relatively reduced responses to monetary penalties in the major depression group emerged in other caudate regions. By contrast, evidence for group differences during reward anticipation was weaker, although participants with major depression showed reduced activation to reward cues in a small sector of the left posterior putamen. In the major depression group, anhedonic symptoms and depression severity were associated with reduced caudate volume bilaterally. Conclusions: These results suggest that basal ganglia dysfunction in major depression may affect the consummatory phase of reward processing. Additionally, morphometric results suggest that anhedonia in major depression is related to caudate volume. C1 Harvard Univ, Dept Psychol, Cambridge, MA 02138 USA.

The authors utilized data from a genomewide association study to examine associations between single nucleotide polymorphisms (SNPs) and the outcome of lithium treatment in two cohorts of patients with bipolar I disorder or bipolar II disorder. Method: The hazard for mood episode recurrence was examined among 1,177 patients with bipolar I disorder or bipolar II disorder, including 458 individuals treated with lithium carbonate or citrate, who were participants in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) cohort. SNPs showing the greatest evidence of association in Cox regression models were then examined for association with positive lithium response among 359 bipolar I or II disorder patients treated with lithium carbonate or citrate in a second cohort from the University College London. Results: The strongest association in the STEP-BD cohort (minimum p=5.5x10(-7)) was identified for a region on chromosome 10p15 (rs10795189). Of the regions showing suggestive evidence (p<5x10(-4)) of association with lithium response, five were further associated with positive lithium response in the University College London cohort, including SNPs in a region on chromosome 4q32 spanning a gene coding for the glutamate/alpha-amino-3-hydroxy-5-methyl-4-isoxazolpropionate (AMPA) receptor GRIA2. Conclusions: Multiple novel loci merit further examination for association with lithium response in bipolar disorder patients, including one region that spans the GRIA2 gene, for which expression has been shown to be regulated by lithium treatment.

Objectives: To investigate the longitudinal association between regular physical activity and asthma exacerbations. Methods: A total of 2,818 women with asthma from a large U.S. cohort (the Nurses' Health Study) were monitored from 1998 to 2000. Physical activity was self-reported at baseline, using a validated questionnaire, and categorized in quintiles. Exacerbations during follow-up were defined as a self-report of asthma-related hospitalization, emergency department visit, or urgent office visit. Baseline information about severity of asthma, treatment, previous exacerbations, sociodemographic factors, smoking, and other potential confounders was obtained. Measurements and Main Results: Participants had a mean age of 63 years, and 71% had mild-to-moderate persistent asthma. About half of the women were ever-smokers (48% former, 6% current), and median physical activity was 10 MET hours/week (equivalent to walking at a brisk pace for 20 minutes three times per week). Risk of exacerbations during follow-up decreased with increasing level of physical activity. In a multivariate logistic regression model, the higher level of physical activity, the lower risk of admission (odds ratio 0.85,0.81, 0.78, and 0.76, for the 2nd, 3rd, 4th, and 5th quintiles compared with the 1st quintile, P for trend = 0.05). There were no relevant differences on stratifying by age group, smoking status, body mass index, baseline use of inhaled corticosteroids, or previous exacerbations. Conclusions: Regular physical activity was associated with reduced risk of exacerbations in women with asthma in this longitudinal study.

TI Surgical outcomes of open cholecystectomy in the laparoscopic era SO AMERICAN JOURNAL OF SURGERY LA English DT Article DE Cholecystitis; Cholelithiasis; Laparoscopic conversion to open procedure; Laparoscopy; Open cholecystectomy ID LEARNING-CURVE; NATIONWIDE; CONVERSION; MORTALITY AB BACKGROUND: Although laparoscopic cholecystectomy has become the standard of care for symptomatic cholelithiasis and cholecystitis, 10% to 30% of cholecystectomies are still performed in open fashion. Because the total number of cholecystectomies is increasing with time, the average patient undergoing open cholecystectomy in the laparoscopic era is older and has more comorbidities. METHODS: The records of 1629 consecutive patients who underwent cholecystectomy from July 1997 to September 2006 were evaluated. Analysis of variance, chi-square test, logistic regression, and linear regression were used to compare the following outcomes: length of procedure, length of stay, readmission (within 15 days and within 31 days), reoperation, and complication. RESULTS: Major complications (death, bile duct injury, bile leak, or bleeding requiring reoperation or transfusion) occurred more frequently in laparoscopic cholecystectomy patients who were coverted to open procedure (5.9%) than in those who underwent open cholecystectomy (4.4%). Mortality rates were 2.9%, 1.5%, and 0% for open, converted, and laparoscopic cholecystectomy, respectively. CONCLUSIONS: Older patients, male patients, and patients with previous upper abdominal surgery are at higher risk for mortality. They should be considered for open cholecystectomy given their increased likelihood of major complications when laparoscopic cholecystectomy is converted to open surgery. (C) 2009 Elsevier Inc.

One previous clinical study suggested that UC-PSC patients reveal a high rate of rectal sparing and backwash ileitis. The purpose of this study was to systematically evaluate the pathologic characteristics and distribution of colonic disease in UC-PSC patients and to compare the results with a matched control group of UC patients without PSC. Methods: Forty UC-PSC patients and 40 matched UC patients without PSC (controls) were identified from the files of 3 hospitals between the years 1989 and 2005. Clinical. endoscopic, and follow-up data (including incidence of pouchitis) were evaluated, and a detailed pathologic evaluation of biopsy and resection specimens (when available) was performed in a blinded fashion. The degree of activity and chronicity in mucosal biopsies and/or tissue from resection specimens was graded on a 5-point grading system (0 to 4), and each portion of the colon (cecum, ascending colon, transverse colon, descending colon, rectum) was assessed separately. Rectal sparing and patchiness of disease Were evaluated, and scored us either absolute or relative depending on the complete absence of inflammatory disease in the former. or less inflammatory disease in the rectum compared with other parts of the colon in the latter. Results: In this matched case-control study, UC-PSC patients presented at a significantly earlier-age (24.5 y), had a higher prevalence rate of pancolitis (85%), and an overall significantly lower grade of inflammation in the colon (mean grade: 2.09 +/- 0.085) compared with UC controls (mean age: 33.8 y, 2 pancolitis: 45%, inflammation grade: 2.59 +/- 0.91 P < 0.05 for all comparisons). The incidence rate of absolute and relative rectal sparing (27.5%) and of patchy inflammatory disease proximal to the rectum (5.7%) was not significantly different between the UC-PSC cases and the UC controls (25% and 7.9%, respectively). UC-PSC patients had a higher prevalence rate of ileitis (35.7%) and pouchitis (42.8%), but the values were not significantly different from controls (26.9% and 26.6%, respectively). The incidence rate of dysplasia was similar between the 2 patient groups. Conclusions: UC patients with PSC show a propensity for more extensive. but less active, disease but are otherwise characterized by similar pathologic findings compared with UC patients without PSC. Rectal sparing and patchy disease activity is not characteristic of UC patients with PSC.

Many of these patients experience renin-angiotensin-aldosterone system (RAAS) dysregulation, which is important because the RAAS plays a pivotal role in the pathogenesis of hypertension, cardiovascular disease, and renal dysfunction. Data available regarding newer approaches that target the RAAS, including direct renin inhibition and aldosterone receptor antagonism, in patients who often have hypertension are reviewed. Aliskiren. the first direct renin inhibitor, is effective in a number of these patient groups, including those who are black or obese or who have metabolic syndrome, renal impairment, or diabetes. In addition, in the setting of long-term angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy, aldosterone receptor antagonists (spironolactone and eplerenone) provide another rational therapeutic approach for patients whose blood pressure is not controlled by standard therapies.

We evaluated the ability of porcine thymus xenotransplantation to induce human T-cell tolerance using a humanized mouse (hu-mouse) model, where a human immune system is preestablished by implantation of fetal human thymus tissue under the kidney capsule and intravenous injection of CD34(+) hematopoietic stem/progenitor cells. Human T-cell depletion with an anti-CD2 mAb following surgical removal of human thymic grafts prevented the initial rejection of porcine thymic xenografts in hu-mice. In these hu-mice, porcine thymic grafts were capable of supporting human thymopoiesis and T-cell development, and inducing human T-cell tolerance to porcine xenoantigens. Human T cells from these mice responded strongly to third-party pig, but not to the thymic donor swine leukocyte antigen (SLA)-matched pig stimulators in a mixed lymphocyte reaction (MLR) assay. Anti-pig xenoreactive antibodies declined in these hu-mice, whereas antibody levels increased in nontolerant animals that rejected porcine thymus grafts. These data show that porcine thymic xenotransplantation can induce donor-specific tolerance in immunocompetent hu-mice, supporting this approach for tolerance induction in clinical xenotransplantation.

Unfortunately researchers face difficulties inherent to the optimization of complex, multivariable methods and their application to the analysis of rare and often experimentally intractable phosphorylated peptides. Here we describe a platform based on manipulation of magnetic beads in a 96-well format that facilitates rapid evaluation of experimental parameters required for enrichment of phosphopeptides. Optimized methods provided for automated enrichment and subsequent LC-MS/MS detection of over 1000 unique phosphopeptides (similar to 1% FDR) from 50 mu g of cell lysates. In addition we demonstrate use of this platform for identification of phosphopeptides derived from proteins separated by SDS-PAGE and visualized near the detection limit of silver staining.

Recently, the gastrointestinal peptide hormones glucagon-like peptide 1 and amylin have been shown to significantly contribute to this complex physiology. These advances provide the foundation for new treatments for diabetes mellitus. Therapies based on glucagon-like peptide 1 and amylin have now been introduced into clinical practice. Rimonabant, the selective endo-cannabinoid receptor antagonist, had been used in European countries for the treatment of obesity; it has recently been withdrawn for this indication. This drug exhibited therapeutic benefits for metabolic variables and for type 2 diabetes mellitus. Anesthesia providers caring for patients with diabetes mellitus will need to understand the implications of these new therapies in perioperative settings, particularly with respect to side effects and interactions.

The authors hypothesized that minimal neuromuscular blockade (train-of-four [TOF] ratio 0.5-1) increases upper airway collapsibility and impairs upper airway dilator muscle compensatory responses to negative pharyngeal pressure challenges. Methods: Epiglottic and nasal mask pressures, genioglossus electromyogram, respiratory timing, and changes in lung volume were measured in awake healthy volunteers (n = 15) before, during (TOF = 0.5 and 0.8 [steady state]), and after recovery of TOF to unity from rocuronium-induced partial neuromuscular blockade. Passive upper airway closing pressure (negative pressure drops, random order, range +2 to -30 cm H(2)O) and pressure threshold for flow limitation were determined. Results: Upper airway closing pressure increased (was less negative) significantly from baseline by 54 +/- 4.4% (means +/- SEM), 37 +/- 4.2%, and 16 +/- 41% at TOF ratios of 0.5, 0.8, and 1.0, respectively (P < 0.01 vs. baseline for any level). Phasic genioglossus activity almost quadrupled in response to negative (-20 cm H(2)O) pharyngeal pressure at baseline, and this increase was significantly impaired by 57 +/- 44% and 32 +/- 6% at TOF ratios of 0.5 and 0.8, respectively (P < 0.01 vs. baseline). End-expiratory lung volume, respiratory rate, and tidal volume did not change. Conclusion: Minimal neuromuscular blockade markedly increases upper airway closing pressure, partly fly impairing the genioglossus muscle compensatory response. Increased airway collapsibility despite unaffected values for testing ventilation may predispose patients to postoperative respiratory complications, particularly during airway challenges.

TI A Model for Understanding the Impacts of Demand and Capacity on Waiting Time to Enter a Congested Recovery Room SO ANESTHESIOLOGY LA English DT Article; Proceedings Paper CT Annual Meeting of the American-Society-of-Anesthesiologists CY OCT 14-17, 2007 CL San Francisco, CA SP Amer Soc Anesthesiologists ID POSTANESTHESIA CARE-UNIT; LAPAROSCOPIC CHOLECYSTECTOMY PATIENTS; OPERATING-ROOM; COMPUTER-SIMULATION; ANESTHESIA; VARIABILITY; EFFICIENCY; RESOURCES; INDUCTION; DISCHARGE AB Background: When a recovery room is fully occupied, patients frequently wait in the operating room after emerging from anesthesia. The frequency and duration of such delays depend on operating room case volume, average recovery time, and recovery room capacity. Methods: The authors developed a simple yet nontrivial queueing model to predict the dynamics among the operating and recovery rooms as a function of the number of recovery beds, surgery case volume, recovery time, and other parameters. They hypothesized that the model could predict the observed distribution of patients in recovery and on waitlists, and they used statistical goodness-of-fit methods to test this hypothesis against data from their hospital. Numerical simulations and a survey were used to better understand the applicability of the model assumptions in other hospitals. Results: Statistical tests cannot reject the prediction, and the model assumptions and predictions are in agreement with data. The survey and simulations suggest that the model is likely to be applicable at other hospitals. Small changes in capacity, such as addition of three beds (roughly 10% of capacity) are predicted to reduce waiting for recovery beds by approximately 60%). Conversely, even modest caseload increases could dramatically increase waiting. Conclusions: A key managerial insight is that there is a sensitive relationship among caseload and number of recovery beds and the magnitude of recovery congestion. This is typical in highly utilized systems. The queueing approach is useful because it enables the investigation of future scenarios for which historical data arc not directly applicable.

TI Pentobarbital Dose-dependently increases Respiratory Genioglossus Muscle Activity while Impairing Diaphragmatic Function in Anesthetized Rats SO ANESTHESIOLOGY LA English DT Article ID UPPER AIRWAY; NOXIOUS-STIMULATION; PROPOFOL; COLLAPSIBILITY; ANESTHESIA; SLEEP; ISOFLURANE; HALOTHANE; RESPONSES; PRESSURE AB Background: Anesthetics depress both ventilatory and upper airway dilator muscle activity and thus put the upper airway at risk for collapse. However, these effects are agent-dependent and may involve upper airway and diaphragm muscles to varying degrees. The authors assessed the effects of pentobarbital on upper airway dilator and respiratory pump muscle function in rats and compared these results with the effects of normal sleep. Methods: Tracheostomized rats were given increasing doses of pentobarbital to produce deep sedation then light and deep anesthesia, and negative pressure airway stimuli were applied (n = 11). To compare the effects of pentobarbital with those of natural sleep, the authors chronically instrumented rats (n = 10) with genioglossus and neck electromyogram and electroencephalogram electrodes and compared genioglossus activity during wakefulness, sleep (rapid eye movement and non-rapid eye movement), and pentobarbital anesthesia. Results: Pentobarbital caused a dose-dependent decrease in ventilation and in phasic diaphragmatic electromyogram by 11 +/- 0.1%, but it increased phasic genioglossus electromyogram by 23 +/- 0.2%. Natural non-rapid eye movement sleep and pentobarbital anesthesia (10 mg/kg intraperitoneally) decreased respiratory genioglossus electromyogram by 61 +/- 29% and 45 +/- 35%, respectively, and natural rapid eye movement sleep caused the greatest decrease in phasic genioglossus electromyogram (95 +/- 0.3%). Conclusions: Pentobarbital in rats impairs respiratory genioglossus activity compared to the awake state, but the decrease is no greater than seen during natural sleep. During anesthesia, in the absence of pharyngeal airflow, phasic genioglossus activity is increased in a dose-dependent fashion.

TI Experimental Ventilator-induced Lung Injury Exacerbation by Positive End-Expiratory Pressure SO ANESTHESIOLOGY LA English DT Article ID ACUTE RESPIRATORY-DISTRESS; HIGH TIDAL VOLUME; MECHANICAL VENTILATION; PULMONARY-EDEMA; AIRWAY PRESSURES; EXPRESSION; CYTOKINES; MODEL; GENE; RATS AB Background: Previous experimental studies of ventilator-induced lung injury have shown that positive end-expiratory pressure (PEEP) is protective. The authors hypothesized that the application of PEEP during volume-controlled ventilation with a moderately high tidal volume (V(T)) in previously healthy in vivo rats does not attenuate ventilator-induced lung injury if the peak airway pressure markedly increases during the application of PEEP. Methods: Sixty healthy, male Sprague-Dawley rats were anesthetized and randomized to be mechanically ventilated for 4 h at (1) V(T) of 6 ml/kg, (2) V(T) of 20 ml/kg, or (3) V(T) of 20 ml/kg plus 10 cm H(2)O of PEEP. Peak airway pressures, gas exchange, histologic evaluation, mortality, total lung tissue cytokine gene expression, and serum cytokine concentrations were analyzed. Results: Peak airway pressures exceeded 30 cm H(2)O with high V(T) plus PEEP. All lungs ventilated with high V(T) had perivascular edema and inflammatory infiltrates. In addition, those ventilated with PEEP had small hemorrhages foci. Five animals from the high V(T) plus PEEP group died (P = 0.020). Animals ventilated with high V, (with or without PEEP) had a substantial increase in serum interleukin-6 (P = 0.0002), and those ventilated with high V(T) plus PEEP had a 5.5-fold increase in systemic levels of tumor necrosis factor-alpha (P = 0.007). Conclusions: In contrast to previous reports, PEEP exacerbated lung damage and contributed to fatal outcome in an in vivo, mild overdistension model of ventilator-induced lung injury in previously healthy rats. That is, the addition of high PEEP to a constant large V(T) causes injury in previously healthy animals. C1 [Kacmarek, Robert M.] Massachusetts Gen Hosp, Dept Resp Care, Boston, MA 02114 USA.

Understanding the risk perceptions of older individuals who undergo screening will guide these efforts. This paper examines National Lung Screening Trial (NLST) participants' perceptions of risk for lung cancer and other smoking-related diseases. We investigated (1) whether risk perceptions of lung cancer screening participants differed between current and former smokers and (2) which factors (sociodemographic, smoking and medical history, cognitive, emotional, and knowledge) were associated with these risk perceptions. We analyzed baseline data collected from 630 NLST participants prior to their initial screen. Participants were older (55-74 years), heavy (minimum 30 pack years) current or former smokers. A ten-item risk perception measure was developed to assess perceived lifetime risk of lung cancer and other smoking-related diseases. The risk perception measure had excellent internal consistency (alpha = 0.93). Former smokers had lower risk perceptions compared to current smokers. Factors independently associated with high risk perceptions among current smokers included having a personal history of a smoking-related disease, higher lifetime maximum number of cigarettes smoked daily, having lived with a smoker, high worry, high perceived severity of lung cancer and smoking-related diseases, and accurate knowledge of tenfold increased risk of lung cancer for a one pack per day smoker. Factors independently associated with high risk perceptions among former smokers included being White, past history of smoking within 30 min of waking, high worry, and accurate knowledge of tenfold increased risk of lung cancer for a one pack per day smoker. Using a comprehensive risk perception measurement, we found that current and former smokers held different risk perceptions. Former and current smokers' smoking and medical history, race, emotional concerns, behavior change cognitions, and knowledge should be considered during a prescreening risk communication session. We highlight the theoretical and risk communication implications for former and current smokers undergoing lung cancer screening.

The purpose of this study is to assess the degree to which EDs are designed, managed, and supported in ways that ensure patient safety. Methods: This was a validated, psychometrically tested survey of clinicians working in 65 US EDs that assessed clinician perceptions about the EDs' physical environment, staffing, equipment and supplies, nursing, teamwork, safety culture, triage and monitoring, information coordination and consultation, and inpatient coordination. Results: Overall 3,562 eligible respondents completed the survey (response rate=66%). Survey respondents commonly reported problems in 4 systems critical to ED safety: physical environment, staffing, inpatient coordination, and information coordination and consultation. ED clinicians reported that there was insufficient space for the delivery of care most (25%) or some (37%) of the time. Respondents indicated that the number of patients exceeded ED capacity to provide safe care most (32%) or some of the time (50%). Only 41% of clinicians indicated that most of the time specialty consultation for critically ill patients arrived within 30 minutes of being contacted. Finally, half of respondents reported that ED patients requiring admission to the ICU were rarely transferred from the ED to the ICU within 1 hour. Conclusion: Reports by ED clinicians suggest that substantial improvements in institutional design, management, and support for emergency care are necessary to maximize patient safety in US EDs.

Weir Mitchell First described "causalgia" following wartime nerve injury, with its persistent distal limb burning pain, swelling, and abnormal skin color, remperature, and sweating. Similar post-traumatic symptoms were later identified in patients without overt nerve injuries after trauma. This was labeled reflex sympathetic dystrophy (RSD; now complex regional pain syndrome type I [CRPS-I]). The pathophysiology of symptoms is unknown and treatment options are limited. We propose that persistent RSD/CRPS-I is a post-traumatic neuralgia associated with distal degeneration of small-diameter peripheral axons. Small-fiber lesions are easily missed oil examination and are undetected by standard electrophysiological testing. Most CRPS features-spreading pain and skin hypersensitivity, vasomotor instability, osteopenia, edema, and abnormal sweating-are explicable by small-fiber dysfunction. Small Fibers sense pain and temperature but also regulate tissue function through neuroeffector actions. Indeed, small-fiber-predominant polyneuropathies cause CRPS-like abnormalities, and pathological studies of nerves from chronic CRPS-I patients confirm small-fiber-predominant pathology. Small distal nerve injuries in rodents reproduce many CRPS features, further supporting this hypothesis. CRPS symptoms likely reflect combined effects of axonal degeneration and plasticity, inappropriate firing and neurosecretion by residual axons, and denervation supersensitivity. The resulting tissue edema, hypoxia, and secondary central nervous system changes can exacerbate symptoms and perpetuate pathology. Restoring the interest of neurologists in RSD/CRPS should improve patient care and broaden our knowledge of small-fiber functions.

Patients and methods: Women with stage IIIB/IV HER2-overexpressing breast cancer were treated with single-agent lapatinib 1250 or 1500 mg once daily after protocol amendment. Tumor response according to RECIST was assessed every 8 weeks. HER2 expression was assessed in tumor tissue by immunohistochemistry and FISH. Results: Seventy-eight patients were enrolled in the study. Investigator and independent review response rates [complete response (CR) or partial response (PR)] were 7.7% and 5.1%, and clinical benefit rates (CR, PR, or stable disease for >= 24 weeks) were 14.1% and 9.0%, respectively. Median time to progression was 15.3 weeks by independent review, and median overall survival was 79 weeks. The most common treatment-related adverse events were rash (47%), diarrhea (46%), nausea (31%), and fatigue (18%). Conclusions: Single-agent lapatinib has clinical activity with manageable toxic effects in HER2-overexpressing breast cancer that progressed on trastuzumab-containing therapy. Studies of lapatinib-based combination regimens with chemotherapy and other targeted therapies in metastatic and earlier stages of breast cancer are warranted. C1 [Blackwell, K.

Guidelines for endoscopic laser management of early glottic and supraglottic cancer, including contraindications for this treatment modality, are presented. On the basis of all Currently available data, the panel, which critically considered the question of oncological safety, is of the opinion that endoscopic laser resections are oncologically safe when applied judiciously and by a skilled oncological surgeon. Relative contraindications for endoscopic laser resection of laryngeal cancer include instances in which the whole tumor cannot be visualized; large tumors that require removing too much of the functional laryngeal unit, severely decreasing airway protection and leading to aspiration; and cartilage invasion. Specific contraindications for supraglottic cancer include bilateral arytenoid involvement and direct extension into the neck.

Methods: We compared four protocols of celloidin removal, including those using clove oil, acetone, ether-alcohol, and methanol saturated with sodium hydroxide. By optimally fixing our tissue (perfused mice), and keeping constant the fixative type (formalin plus acetic acid), fixation time (25 hours), and decalcification time (ethylene(ethylenediaminetetraacetic acid for 7 days), we determined whether the technique of celloidin removal influenced the immunostaining results. Six antibodies were used with each removal method: prostaglandin D synthase, sodium, potassium adenosine triphosphatase (Na(+),K(+)-ATPase), aquaporin I, connective tissue growth factor, tubulin, and 200 kd neurofilament. Results: Clove oil, acetone, and ether-alcohol resulted in incomplete removal of the celloidin, thereby negatively affecting the results of immunostaining. The methanol-sodium hydroxide method was effective in completely removing the celloidin; it produced the cleanest and most reproducible immunostaining for all six antibodies. Conclusions: Freshly prepared methanol saturated with sodium hydroxide and diluted 1:2 with methanol was the best solvent for removing celloidin from Muse temporal bone sections, resulting in consistent and reproducible immunostaining with the six antibodies tested.

TI Age-Related Lymphatic Dysfunction in Melanoma Patients SO ANNALS OF SURGICAL ONCOLOGY LA English DT Article; Proceedings Paper CT 6th Biennial International-Sentinel-Node-Society Meeting CY FEB 18-20, 2008 CL Sydney, AUSTRALIA SP Int Sentinel Node Soc ID EARLY-STAGE MELANOMA; SENTINEL LYMPHADENECTOMY; PROGNOSTIC-FACTORS; BREAST-CANCER; AGING SKIN; NODE; LYMPHOSCINTIGRAPHY; LYMPHANGIOGENESIS; VISUALIZATION; VALIDATION AB Age-related outcomes have become increasingly common in evaluating patients with melanoma. For instance, as age increases, sentinel node (SN) nonidentification increases and SN positivity decreases. Furthermore, advanced age is a risk factor for in-transit disease. We hypothesized that increasing age is accompanied by alterations in lymphatic function, possibly explaining these findings. Our center's melanoma database was queried to identify patients who underwent successful sentinel node biopsy after lymphoscintigraphy. Records of those treated between 2000 and 2005 were reviewed for age, sex, drainage basin, intraoperative radioactivity, and SN pathology. The 858 patients had a mean age of 55 years; 59% were men. Mean radioactivity in the hottest SN was 5232 counts per second; 179 patients (21%) had SN metastases. SN count rates were significantly and inversely related to age (P < .001 by Pearson correlation, analysis of variance, and chi(2) test). Mean counts per second were 6105, 5883, and 2720 for axillary, inguinal, and cervical basins, respectively (P < .01), and count rates in these basins were consistently lower with increasing age (neck and axilla, P < .001; groin, P = .060; Pearson correlation). Multivariate analysis confirmed an independent inverse association between age and count rates (P < .001), overall and within each primary tumor site. Lymphatic function, as assessed by radiocolloid transit to and uptake within the SN, declines with age. Altered lymphatic function in older patients may modify metastatic patterns; knowledge of this may help clarify findings of reduced nodal positivity and increased in-transit disease in this population.

PI-103 is a inhibitor of PI3K/AKT and mTOR activation. This study aims to determine whether the PI3K/mTOR pathway was active in chordomas and whether their inhibition could lead to decreased proliferation and increased apoptosis. Materials and Methods: Thirteen human chordoma were tested for activation of the PI3K/mTOR pathway. The human chordoma cell line UCH-1 was treated with increasing doses of PI-103. Inhibition of AKT and mTOR was examined and assays assessing proliferation and apoptosis were performed. Results: The chordoma specimen demonstrated activation of the PI3K/mTOR pathway. PI-103 inhibited the AKT and mTOR activation in the UCH-1 cell line. PI-103 inhibited proliferation and induced apoptosis in UCH-1. Conclusion: The PI3K/AKT and mTOR signaling pathway is constitutively activated in chordoma. PI-103 decreases proliferation and induces apoptosis in the UCH-1 via inhibition of the PI3K/mTOR pathway.

Various clinical trials have been initiated using antiapoptotic agents and perifosine, and are truly in the experimental phases. Chondrosarcoma is still therefore considered a surgical disease despite its aggressive features of recurring locally and spreading to the lungs. Bisphosphonates inhibit growth of various cell types, including cancer cells and perhaps chondrosarcoma. Materials and Methods: The effect of different concentrations of alendronate on cell proliferation, migration, apoptosis and cytoskeleton reorganization as well as on the regulation of intracellular protein expression were analyzed for the high-grade chondrosarcoma cell line CS-1. Mevalonate pathway intermediates were used in some experiments to assess mechanistic aspects. Results: Alendronate decreased cell viability of CS-1 by inhibiting cell proliferation and cell migration. Alendronate-induced loss of cell viability led to a sequence of events including apoptosis and cytoskeletal rearrangements. Moreover, changes in the expression levels of various proteins involved in cell proliferation, migration, cell cycle, apoptosis and cytoskeleton reorganization were demonstrated. Conclusion: Alendronate exerts antiproliferative effects by perturbing various signaling pathways in CS-1 cells. These findings may lead to new treatment options for high-grade chondrosarcoma.

In this study, we utilize G. mellonella caterpillars to study host-pathogen interactions with the gram-negative organism Acinetobacter baumannii and determine the utility of this infection model to study antibacterial efficacy. After infecting G. mellonella caterpillars with a reference A. baumannii strain, we observed that the rate of G. mellonella killing was dependent on the infection inoculum and the incubation temperature postinfection, with greater killing at 37 C than at 30 C (P = 0.01). A. baumannii strains caused greater killing than the less-pathogenic species Acinetobacter baylyi and Acinetobacter lwoffii (P < 0.001). Community-acquired A. baumannii caused greater killing than a reference hospital-acquired strain (P < 0.01). Reduced levels of production of the quorum-sensing molecule 3-hydroxy-C(12)-homoserine lactone caused no change in A. baumannii virulence against G. mellonella. Treatment of a lethal A. baumannii infection with antibiotics that had in vitro activity against the infecting A. baumannii strain significantly prolonged the survival of G. mellonella caterpillars compared with treatment with antibiotics to which the bacteria were resistant. G. mellonella is a relatively simple, nonmammalian model system that can be used to facilitate the in vivo study of host-pathogen interactions in A. baumannii and the efficacy of antibacterial agents.

Despite the fact that skeletal muscle glucose uptake plays a major role in normal conditions, in insulin resistance, and type II diabetes, the details of GLUT4 translocation and the intracellular signalling involved have not been fully described. A main reason is that the majority of experiments have been carried out in muscle cultures in vitro. In vitro cultured muscle is not fully differentiated and, therefore, diverges from real muscle, in that it has lower expression of GLUT4, an underdeveloped or nonexistent t-tubule network, and a reduced or nonexistent response to insulin. Thus, experiments carried out in cultured muscle cell systems might give misleading results on how GLUT4 translocation and the signalling involved takes place. To address this problem, a confocal imaging technique has been developed that allows delineation of the spartial and spatial distribution of GFP-tagged GLUT4 (GLUT4-GFP) translocation in living muscle fibers in situ in anesthetized mice. The effects of stimuli with insulin or in situ muscle contractions in fully differentiated muscle fibers can now be studied before, during, and after applying stimuli. Initial analysis of insulin-stimulated GLUT4-GFP translocation showed a delay in maximal translocation between the sarcolemma and t-tubules. Corresponding to the delay, we found that fluorescent tagged insulin reaches the sarcolemma first and then, with a delay, diffuses into the t-tubule system, enabling interaction with local insulin receptors and, in turn, triggering local insulin signalling and local GLUT4 translocation. In parallel, we showed that the majority of GLUT4 depot vesicles do not move long distances but are depleted locally in the sarcolemma or t-tubule regions. Analysis of GLUT4 translocation in insulin-resistant muscle showed that, primarily, GLUT4 recruitment in the t-tubule region is affected. We have now analysed the kinetics of contraction-mediated GLUT4 translocation and reinternalization, as well as dilineated some of the key signalling points involved in these processes.

Aims. - To describe the characteristics and evolution of patients non-compliant to study drug in the prospective, randomized, double-blind CHARISMA trial. Methods. - Of 15,603 patients aged 45 or older years with established atherothrombotic disease (coronary artery disease, stroke, peripheral. arterial disease) or multiple cardiovascular risk factors, 2999 permanently interrupted (withdrawers) study drug (clopidogrel or placebo) during follow-up. The primary endpoint was first occurrence since randomization of myocardial infarction, stroke or cardiovascular death. Results. - Withdrawers displayed a higher risk profile and rates of death/myocardial infarction/stroke (13.5% versus 5.6%; hazard ratio [HR]: 3.18; 95% confidence interval [CI]: 3.05-3.32; p<0.001) and severe bleeding (4.9% versus 0.7%; odds ratio [OR]: 7.42; 95% CI: 5.67-9.70; p<0.001) versus non-withdrawers. Death/myocardial infarction/stroke occurred after an average of 228days (95%CI: 197-258) and was less frequent in patients assigned to clopidogrel versus placebo (9.7% versus 11.9%; HR: 0.80; 95%CI: 0.64-1.00; p=0.051); the rate of severe bleeding was the same (4.0% versus 4.3%; OR: 0.92; 95%CI: 0.65-1.32; p=0.66). Among withdrawers, initial clopidogrel treatment was an independent correlate of survival (HR: 0.74, 95%CI: 0.59-0.93; p=0.011), but not severe bleeding (OR: 0.94; 95% CI: 0.65-1.35; p=0.74). Kaplan-Meier curves for the primary endpoint suggested no rebound effect or disease reactivation after discontinuation of clopidogrel compared with placebo. Conclusions. - Patients who stopped medication had increased rates of ischaemic and bleeding events and mortality. Patients initially on clopidogrel had fewer ischaemic events than those on placebo; discontinuation was not associated with any clinically detectable rebound effect.

Design: Retrospective cohort study. Setting: Medical and neuroscience intensive care units and neurological wards. Patients: Three hundred consecutive nonelective continuous electroencephalographic monitoring studies, performed on 287 individual inpatients over a 27-month period. Main Outcome Measures: Epileptiform electroencephalographic abnormalities and changes in antiepileptic drug (AED) therapy based on the electroencephalographic findings. Results: The findings from the continuous electroencephalographic monitoring led to a change in AED prescribing in 52% of all studies with initiation of an AED therapy in 14%, modification of AED therapy in 33%, and discontinuation of AED therapy in 5% of all studies. Specifically, the detection of electrographic seizures led to a change in AED therapy in 28% of all studies. Conclusions: The findings of continuous electroencephalographic monitoring resulted in a change in AED prescribing during or after half of the studies performed. Most AED changes were made as a result of the detection of electrographic seizures.

TI Prevalence of Dry Eye Disease Among US Men Estimates From the Physicians' Health Studies SO ARCHIVES OF OPHTHALMOLOGY LA English DT Article ID HUMAN MEIBOMIAN GLAND; OCULAR SURFACE; WORKSHOP 2007; SERUM CONCENTRATIONS; ANDROGEN DEFICIENCY; SUBCOMMITTEE; POPULATION; SECRETIONS; HORMONE; EPIDEMIOLOGY AB Objective: To estimate the prevalence and risk factors for dry eye disease (DED) among US men. Methods: Cross-sectional prevalence survey among male participants 50 years and older in the Physicians' Health Studies I (N = 18 596) and II (N = 6848). We defined DED as the presence of clinically diagnosed dry eye or severe symptoms (both dryness and irritation constantly or often). We calculated the age-standardized prevalence of DED adjusted to the age distribution of US men in 2004 and projected estimates forward to 2030. We compared DED prevalence with a similar cohort of women and examined associations with possible risk factors. Results: The prevalence of DED increased with age, from 3.90% among men aged 50 to 54 years to 7.67% among men 80 years and older (P for trend < .001). High blood pressure (odds ratio, 1.28; 95% confidence interval, 1.12-1.45) and benign prostatic hyperplasia (odds ratio, 1.26; 95% confidence interval, 1.09-1.44) were associated with a higher risk of DED. Use of antidepressants, antihypertensives, and medications to treat benign prostatic hyperplasia were also associated with increased risk of DED. The age-standardized prevalence of DED was 4.34%, or 1.68 million men 50 years and older, and is expected to affect more than 2.79 million US men by 2030. Conclusions: Dry eye disease is prevalent and increases with age, hypertension, benign prostatic hyperplasia, and antidepressant use.

TI Peace of Mind and Sense of Purpose as Core Existential Issues Among Parents of Children With Cancer SO ARCHIVES OF PEDIATRICS & ADOLESCENT MEDICINE LA English DT Article ID PROGNOSTIC DISCLOSURE; LIFE; END; ILLNESS; PATIENT; CARE; COMMUNICATION; SCALE; PREFERENCES; COLLUSION AB Objective: To evaluate issues experienced by parents of children with cancer and factors related to parents' ability to find peace of mind. Design: Cross-sectional survey. Setting: Dana-Farber Cancer Institute and Children's Hospital, Boston, Massachusetts. Participants: One hundred ninety-four parents of children with cancer (response rate, 70%) in the first year of cancer treatment. Main Outcome Measure: The Functional Assessment of Chronic Illness Therapy-Spiritual Well-being sense of meaning subscale. Results: Principal components analysis of Functional Assessment of Chronic Illness Therapy-Spiritual Wellbeing sense of meaning subscale responses identified 2 distinct constructs, peace of mind (Cronbach alpha = .83) and sense of purpose (Cronbach alpha = .71). Scores ranged from 1 to 5, with 5 representing the strongest sense of peace or purpose. One hundred forty-seven of 181 parents (81%) scored 4 or higher for questions related to sense of purpose (mean [SD] score, 4.4 [0.6]). Only 44 of 185 parents (24%) had scores in the same range for peace of mind (mean [SD] score, 3.2 [0.9]) (P < .001). In a multivariable logistic regression model, parents had higher peace of mind scores when they also reported that they trusted the oncologist's judgment (odds ratio [OR] = 6.65; 95% confidence interval [CI], 1.47-30.02), that the oncologist had disclosed detailed prognostic information (OR = 2.05; 95% CI, 1.14-3.70), and that the oncologist had provided high-quality information about the cancer (OR = 2.54; 95% CI, 1.11-5.79). Peace of mind was not associated with prognosis (OR = 0.74; 95% CI, 0.41-1.32) or time since diagnosis (OR = 1.00; 95% CI, 0.995-1.003). Conclusions: Physicians may be able to facilitate formulation of peace of mind by giving parents high-quality medical information, including prognostic information, and facilitating parents' trust.

TI HLA-DR4 as a Risk Allele for Autism Acting in Mothers of Probands Possibly During Pregnancy SO ARCHIVES OF PEDIATRICS & ADOLESCENT MEDICINE LA English DT Article; Proceedings Paper CT 37th Annual Meeting of the Child-Neurology-Society CY NOV 05-08, 2008 CL Santa Clara, CA SP Child Neurol Soc ID MATERNAL IMMUNE-SYSTEM; NONSPECIFIC STIMULATION; LINKAGE DISEQUILIBRIUM; FETAL MALFORMATIONS; TRANSMISSION TEST; GENE; DISORDERS; ASSOCIATION; HAPLOTYPE; REELIN AB Objectives: To test whether HLA-DR4 acts in the mother, possibly during pregnancy, to contribute to the phenotype of autistic disorder in her fetus. Design: Transmission disequilibrium testing in case mothers and maternal grandparents. Setting: Previous studies have consistently shown increased frequency of HLA-DR4 in probands with autism and their mothers, but not their fathers. However, this has been documented only in case-control studies and not by a more direct study design to determine whether HLA-DR4 acts in mothers during pregnancy to contribute to autism in their affected offspring. Participants: We genotyped for HLA-DR alleles in members of 31 families with parents and maternal grandparents. Probands with autism were tested using the Autism Diagnostic Observation Schedule-Western Psychological Services and Autism Diagnostic Interview, Revised. There was 80% power to detect an odds ratio of 3.6. Participants were all families from New Jersey and were similar in number to earlier studies of autism and HLA-DR4. Outcome Measures: Analysis was by standard transmission disequilibrium testing. As a secondary test we examined the possibility of maternal imprinting. Results: Significant transmission disequilibrium for HLA-DR4 was seen (odds ratio, 4.67; 95% confidence interval, 1.34-16.24; P = .008) for transmissions from maternal grandparents to mothers of probands, supporting a role for HLA-DR4 as an autism risk factor acting in mothers during pregnancy. Transmission disequilibrium was not seen for HLA-DR4 transmissions from parents to probands or from mothers to probands. Conclusions: The HLA-DR4 gene may act in mothers of children with autism during pregnancy to contribute to autism in their offspring. Further studies are required to confirm these findings.

TI A Preliminary Model of Wheelchair Service Delivery SO ARCHIVES OF PHYSICAL MEDICINE AND REHABILITATION LA English DT Article DE Health care disparities; Models, theoretical; Rehabilitation; Wheelchairs ID SPINAL-CORD-INJURY; TECHNOLOGY OUTCOMES RESEARCH; QUALITY-OF-LIFE; ASSISTIVE TECHNOLOGY; MANUAL WHEELCHAIRS; DECISION-MAKING; REHABILITATION; PARTICIPATION; SATISFACTION; INDIVIDUALS AB Objective: To integrate and expand on previously published models of wheelchair service delivery, and provide a preliminary framework for developing more comprehensive, descriptive models of wheelchair service delivery for adults with spinal cord injury within the U.S. health care system. Design: Literature review and a qualitative analysis of in-depth interviews. Setting: Not applicable. Participants: Ten academic, clinical, regulatory. and industry experts (Department of Veterans Affairs [VA] and non-VA) in wheelchair service delivery. Interventions: Not applicable. Main Outcome Measures: Interviewees were asked to discuss the full range of variables and stakeholders involved in wheelchair service delivery, and to limit their scope to the provision of primary subsequent or replacement chains (not backup chairs) to adults within the United States. Results: Most experts we interviewed stressed that clients who require a wheelchair play a central role in the wheelchair service delivery process. Providers (including clinicians. rehabilitation engineers, and rehabilitation counselors) are also critical stakeholders. More so than in other health care settings, Suppliers play ail integral role in the provision of wheelchairs to clients and may significantly influence the appropriateness of the wheelchair provided. Suppliers often have a direct role in wheelchair service delivery through their interactions with the clinician and/or client. This model also identified a number of, system-level factors (including facility administration and Standards. policies, and regulations) that influence wheelchair service delivery and ultimately the appropriateness of the wheelchair provided. Conclusions: We developed a detailed, descriptive model of wheelchair service delivery that integrates the delivery process and device outcomes, and includes the patient-level, provider-level. and system-level factors that may directly influence those processes and outcomes. We believe that this detailed model can help clinicians and researchers describe and consider the complexities of wheelchair service delivery. It can be used to identify factors that may be related to disparities in wheelchair service delivery and in the appropriateness of the wheelchair prescribed. Further, this model can help researchers and clinicians identify factors that may be related to disparities in wheelchair service delivery, and intervene to reduce such disparities.

Hepatic portal venous gas is frequently associated with acute mesenteric ischemia, accounting for most of the HPVG-associated mortality. While early studies were necessarily dependent on plain abdominal radiography, modern high-resolution CT has revealed a host of benign conditions in which HPVG has been reported that do not require emergent surgery. Data Sources: Patient records from our institution over the last 10 years and relevant studies from BioMed Central, CENTRAL, PubMed, and PubMed Central. In addition, references cited in selected works were also used as source data. Study Selection: Patient records were selected if the CT or radiograph findings matched the term hepatic portal venous gas. Studies were selected based on the search terms hepatic portal venous gas or portal venous gas. Data Extraction: Quantitative and qualitative data were quoted directly from cited work. Data Synthesis: Early studies of HPVG were based on plain abdominal radiography and a literature survey in 1978 found an associated mortality rate of 75%, primarily due to ischemic bowel disease. Modern abdominal CT has resulted in the detection of HPVG in more benign conditions, and a second literature survey in 2001 found a total mortality of only 39%. While the pathophysiology of HPVG is, as yet, unclear, changing abdominal imaging technology has altered the significance of this radiologic finding. Hepatic portal venous gas therefore predicts high risk of mortality (>50%) if detected by plain radiography or by CT in a patient with additional evidence of necrotic bowel. If detected by CT in patients after surgical or endoscopic manipulation, the clinician is advised that there is no evidence of increased risk. If HPVG is detected by CT in patients with active peptic ulcer disease, intestinal obstruction and/or dilatation, or mucosal diseases such as Crohn disease or ulcerative colitis, caution is warranted, as risk of death may approach 20% to 30%. Conclusion: The finding of HPVG alone cannot be an indication for emergency exploration, and we have developed an evidence-based algorithm to guide the clinician in management of patients with HPVG.

TI The Relationship Between Focal Erosions and Generalized Osteoporosis in Postmenopausal Women With Rheumatoid Arthritis SO ARTHRITIS AND RHEUMATISM LA English DT Article ID BONE-MINERAL DENSITY; X-RAY RADIOGRAMMETRY; DISEASE-ACTIVITY; JOINT DAMAGE; TREATMENT STRATEGIES; RECENT-ONSET; BASE-LINE; VITAMIN-D; PROGRESSION; DENOSUMAB AB Objective. Among rheumatoid arthritis (RA) patients who have had the disease for 10 years, more than half have focal erosions, and the risk of fracture is doubled. However, there is little information about the potential relationship between focal erosions and bone mineral density (BMD). The aim of this study was to determine whether lower BMD is associated with higher erosion scores among patients with RA. Methods. We enrolled 163 postmenopausal women with RA, none of whom were taking osteoporosis medications. Patients underwent dual x-ray absorptiometry at the hip and spine and hand radiography, and completed a questionnaire. The hand radiographs were scored using the Sharp method, and the relationship between BMD and erosions was measured using Spearman's correlation coefficients and adjusted linear regression models. Results. Patients had an average disease duration of 13.7 years, and almost all were taking a disease-modifying antirheumatic drug. Sixty-three percent were rheumatoid factor (RF) positive. The median modified Health Assessment Questionnaire score was 0.7, and the average Disease Activity Score in 28 joints was 3.8. The erosion score was significantly correlated with total hip BMD (r = -0.33, P < 0.0001), but not with lumbar spine BMD (r = -0.09, P = 0.27). Hip BMD was significantly lower in RF-positive patients versus RF-negative patients (P = 0.02). In multivariable models that included age, body mass index, and cumulative oral glucocorticoid dose, neither total hip BMD nor lumbar spine BMD was significantly associated with focal erosions. Conclusion. Our results suggest that hip BMD is associated with focal erosions among postmenopausal women with RA, but that this association disappears after multivariable adjustment. While BMD and erosions may be correlated with bone manifestations of RA, their relationship is complex and influenced by other disease-related factors.

Cultural differences in crewmembers and mission control personnel during two space station programs. Aviat Space Environ Med 2009; 80:532-40. Introduction: Cultural differences among crewmembers and mission control personnel can affect long-duration space missions. We examine three cultural contrasts: national (American vs. Russian); occupational (crewmembers vs. mission control personnel); and organizational [Mir space station vs. International Space Station (ISS)]. Methods: The Mir sample included 5 American astronauts, 8 Russian cosmonauts, and 42 American and 16 Russian mission control personnel. The ISS sample included 8 astronauts, 9 cosmonauts, and 108 American and 20 Russian mission control personnel. Subjects responded to mood and group climate questions on a weekly basis. The ISS sample also completed a culture and language questionnaire. Results: Crewmembers had higher scores on cultural sophistication than mission control personnel, especially American mission control. Cultural sophistication was not related to mood or social climate. Russian subjects reported greater language flexibility than Americans. Crewmembers reported better mood states than mission control, but both were in the healthy range. There were several Russian-American differences in social climate, with the most robust being higher work pressure among Americans. Russian-American social climate differences were also found in analyses of crew only. Analyses showed Mir-ISS differences in social climate among crew but not in the full sample. Discussion: We found evidence for national, occupational, and organizational cultural differences. The findings from the Mir space station were essentially replicated on the ISS. Alterations to the ISS to make it a more user-friendly environment have still not resolved the issue of high levels of work pressure among the American crew.

Undergraduate participants were selected based on a 2-phase screening process, including a semistructured diagnostic interview. The final sample consisted of 101 bipolar spectrum participants and 100 demographically matched normal controls. Participants who completed up to 3 follow-up visits, approximately every 4 months, as part of a longitudinal study were included in the current study. Life events did not predict social rhythm regularity and social rhythm regularity inconsistently predicted affective symptoms. However, life events, particularly social rhythm disruption (SRD) events, did predict depressive symptoms and episodes, and less consistently predicted hypo(manic) symptoms and episodes. Thus, the current study obtained mixed support for social zeitgeber theory.

In the first study, among a sample of 395 individuals at an urban commuter campus, self-reports of both emotion regulation difficulties and aspects of mindfulness accounted for unique variance in GAD symptom severity, above and beyond variance shared with depressive and anxious symptoms, as well as variance shared with one another. In the second study, individuals with GAD (n = 16) reported significantly lower levels of mindfulness and significantly higher levels of difficulties in emotion regulation than individuals in a nonanxious control group (n = 16). Results are discussed in terms of directions for future research and potential implications for treatment development. C1 [Roemer, Lizabeth] Univ Massachusetts, Dept Psychol, Boston, MA 02125 USA.

These DNA-modification processes are initiated by AID (activation-induced cytidine deaminase), a DNA cytidine deaminase predominantly expressed in activated B-cells. AID is post-transcriptionally regulated via multiple mechanisms, including microRNA regulation, nucleocytoplasmic shuttling, ubiquitination and phosphorylation. Among these regulatory processes, AID phosphorylation at Ser(38) has been a focus of particularly intense study and debate. In the present paper, we discuss recent biochemical and mouse genetic studies that begin to elucidate the functional significance of AID Ser(38) phosphorylation in the context of the evolution of this mode of AID regulation and the potential roles that it may play in activated B-cells during a normal immune response.

Until recently, identifying and validating genetic alterations in tumors that contribute to cancer involved painstaking efforts focused primarily on single mutations. However, the application of whole genome approaches to the study of cancer now makes it possible to contemplate performing systematic characterizations of the structural basis of cancer by identifying mutations associated with each cancer type. In parallel, recent technological advances also make it possible to methodically characterize the function of putative oncogenes and tumor suppressor genes. The integration of these approaches now provides the means to not only derive a complete molecular description of cancer but will also provide well-validated targets for the development of therapeutic agents.

Development of thrombosis-specific molecular imaging agents to detect and monitor thrombogenesis and fibrinolysis in vivo could improve the diagnosis, risk stratification, and treatment of thrombosis syndromes. To this end, we have synthesized efficient multimodal nanoagents targeted to two different constituents of thrombi, namely, fibrin and activated factor XIII. These agents are targeted via the conjugation of peptide-targeting ligands to the surface of fluorescently labeled magnetic nanoparticles. As demonstrated by in vitro and in vivo studies, both nanoagents possess high affinities for thrombi, and enable mutimodal fluorescence and magnetic resonance imaging.

TI Local drug delivery with a self-contained, programmable, microfluidic system SO BIOMEDICAL MICRODEVICES LA English DT Article DE Drug delivery; Microsystems; Microfluidics; Controlled release; Hearing; Cochlea ID GUINEA-PIG; IN-VIVO; MICRONEEDLES; MICROCHIP AB The development and optimization of many new drug therapies requires long-term local delivery with controlled, but variable dosage. Current methods for chronic drug delivery have limited utility because they either cannot deliver drugs locally to a specific organ or tissue, do not permit changes in delivery rate in situ, or cannot be used in clinical trials in an untethered, wearable configuration. Here, we describe a small, self-contained system for liquid-phase drug delivery. This system enables studies lasting several months and infusion rates can be programmed and modified remotely. A commercial miniature pump is integrated with microfabricated components to generate ultralow flow rates and stroke volumes. Solutions are delivered in pulses as small as 370 nL, with pulses delivered at any interval of 1 min or longer. A unique feature of the system is the ability to infuse and immediately withdraw liquid, resulting in zero net volume transfer while compounds are exchanged by mixing and diffusion with endogenous fluid. We present in vitro results demonstrating repeatability of the delivered pulse volume for nearly 3 months. Furthermore, we present in vivo results in an otology application, infusing into the cochlea of a guinea pig a glutamate receptor antagonist, which causes localized and reversible changes in auditory sensitivity.

We examined prospective outcomes during up to two years of naturalistic treatment among 3,658 adult bipolar I and II outpatients participating in a multicenter clinical effectiveness study, the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD). Age at illness onset was identified retrospectively by clinician assessment at study entry. Compared to patients with onset of mood symptoms after age 18 years (n = 1,187), those with onset before age 13 years (n = 1,068) experienced earlier recurrence of mood episodes after initial remission, fewer days of euthymia, and greater impairment in functioning and quality of life over the two-year follow-up. Outcomes for those with onset between age 13 and 18 years (n = 1,403) were generally intermediate between these two groups. Consistent with previous reports in smaller cohorts, adults with retrospectively obtained early-onset bipolar disorder appear to be at greater risk for recurrence, chronicity of mood symptoms, and functional impairment during prospective observation.

TI The role of phosphodiesterase 3 in endotoxin-induced acute kidney injury SO BMC INFECTIOUS DISEASES LA English DT Article ID ACUTE-RENAL-FAILURE; NITRIC-OXIDE SYNTHASE; PROXIMAL TUBULE INJURY; ISCHEMIA/REPERFUSION INJURY; CELL INJURY; RAT; LIPOPOLYSACCHARIDE; CAMP; INHIBITION; MECHANISMS AB Background: Acute kidney injury frequently accompanies sepsis. Endotoxin is known to reduce tissue levels of cAMP and low levels of cAMP have been associated with renal injury. We, therefore, hypothesized that endotoxin induced renal injury by activating phosphodiesterase 3 (PDE3) which metabolizes cAMP and that amrinone an inhibitor of PDE3 would prevent the renal injury. Methods: Animals were divided into three groups (n = 7/group): 1) Control (0.9% NaCl infusion without LPS); 2) LPS (0.9% NaCl infusion with LPS); 3) Amrinone+LPS (Amrinone infusion with LPS). Either lipopolysaccharide (LPS) or vehicle was injected via the jugular vein and the rats followed for 3 hours. We explored the expression of PDE3 isoenzymes and the concentrations of cAMP in the tissue. Results: The PDE3B gene but not PDE3A was upregulated in the kidney of LPS group. Immunohistochemistry also showed that PDE3B was expressed in the distal tubule in the controls and LPS caused PDE3B expression in the proximal as well. However, PDE3A was not expressed in the kidney either in the control or LPS treated groups. Tissue level of cAMP was decreased after LPS and was associated with an increase in blood urea nitrogen, creatinine, ultrastructural proximal tubular changes, and expression of inducible nitric oxide synthase (iNOS) in the endotoxemic kidney. In septic animals the phosphodiesterase 3 inhibitor, amrinone, preserved the tissue cAMP level, renal structural changes, and attenuated the increased blood urea nitrogen, creatinine, and iNOS expression in the kidney. Conclusion: These findings suggest a significant role for PDE3B as an important mediator of LPS-induced acute kidney injury.

Relations between body image (BI) and health locus of control (HLC) were investigated in male patients undergoing evaluation for incisional hernia repair (n = 32) and non-hernia controls (n = 34). Analyses revealed that patients with incisional hernias reported significantly less satisfaction with general appearance and appearance of the mid-torso than non-hernia controls. Although HLC beliefs did not vary by group, post hoc analyses revealed several significant relations between BI factors and HLC beliefs. Results suggest that poor BI is a significant area of concern among patients with incisional hernias. (C) 2009 Elsevier Ltd. All rights reserved.

Images were selected from the Alzheimer's Disease Neuroimaging Initiative database (Control N = 15, Mild-Moderate AD N = 15). The images were segmented using a semi-automated analysis program. Four coronal and three axial profiles of the cerebral cortical ribbon were created. The fractal dimensions (D(f)) of the cortical ribbons were then computed using a box-counting algorithm. The mean D(f) of the cortical ribbons from AD patients were lower than age-matched controls on six of seven profiles. The fractal measure has regional variability which reflects local differences in brain structure. Fractal dimension is complementary to volumetric measures and may assist in identifying disease state or disease progression.

TI Human Milk Adiponectin Is Associated with Infant Growth in Two Independent Cohorts SO BREASTFEEDING MEDICINE LA English DT Article ID IGF-I LEVELS; BREAST-MILK; RANDOMIZED-TRIAL; POTENTIAL ROLE; CORD BLOOD; OBESITY; WEIGHT; LEPTIN; ACRP30/ADIPONECTIN; CHILDHOOD AB Background: Adiponectin, a circulating adipocyte protein, is associated with lower obesity. We have previously shown that adiponectin is present in human milk. This study determined whether higher milk adiponectin is associated with infant growth and investigated milk adiponectin's oligomeric form. Design and Methods: This is a study of two parallel longitudinal cohorts of breastfed infants born between 1998 and 2005. Forty-five mother-infant pairs from Cincinnati, OH and 277 mother-infant pairs from Mexico City, Mexico were analyzed. All participants were healthy, term infants breastfed at least 1 month who completed 6 months of follow-up. Monthly milk samples (n = 1,379) up to 6 months were assayed for adiponectin by radioimmunoassay. Infant weight-for-age, length-for-age, and weight-for-length Z-scores up to 6 months of age were calculated using World Health Organization standards. Repeated-measures analysis was conducted. The structural form of human milk adiponectin was assessed by western blot. Results: In the population studies, initial milk adiponectin was 24.0 +/- 8.6 mu g/L and did not differ by cohort. Over the first 6 months, higher milk adiponectin was associated with lower infant weight-for-age Z-score (-0.20 +/- 0.04, p < 0.0001) and weight-for-length Z-score (-0.29 +/- 0.08, p = 0.0002) but not length-for-age Z-score, adjusted for covariates, with no difference by cohort. By western blot, human milk adiponectin was predominantly in the biologically active high-molecular-weight form. Conclusions: Our data suggest milk adiponectin may play a role in the early growth and development of breastfed infants.

Data on therapy for subtypes other than gastric mucosa-associated lymphoid tissue (MALT) lymphoma has been largely limited to retrospective case series. This prospective phase 2 study of fludarabine and rituximab for the treatment of marginal zone lymphomas enrolled 26 patients, 14 with nodal MZL, eight with MALT lymphomas and four with splenic MZL; 81% were receiving initial systemic therapy. Only 58% [95% confidence interval (CI) 37-77%] of patients completed the planned six cycles, due to significant haematological, infectious and allergic toxicity. Four late toxic deaths occurred due to infections [15% (95% CI 4.3-35%)], two related to delayed bone marrow aplasia and two related to myelodysplastic syndrome. Nonetheless, the overall response rate was 85% (95% CI 65-96%), with 54% complete responses. The progression-free survival at 3.1 years of follow-up is 79.5% (95% CI 63-96%). We conclude that, although concurrent fludarabine and rituximab given at this dose and schedule is a highly effective regimen in the treatment of MZLs, the significant haematological and infectious toxicity observed both during and after therapy is prohibitive in this patient population, emphasizing the need to study MZLs as a separate entity.

We tested this hypothesis by comparing the outcomes of 435 B-cell lymphoma patients who received allogeneic transplantation from 1999 to 2004 in the Center for International Blood and Marrow Transplant Research database: 179 subjects who received rituximab within 6 months prior to transplantation (RTX cohort) and 256 subjects who did not receive RTX within 6 months prior to transplantation (No-RTX cohort). The RTX cohort had a significantly lower incidence of treatment-related mortality (TRM) [relative risk (RR) = 0.68; 95% confidence interval (CI), 0.47-1.0; P = 0.05], lower acute grade II-IV (RR = 0.72; 95% CI, 0.53-0.97; P = 0.03) and III-IV GVHD (RR = 0.55; 95% CI, 0.34-0.91; P = 0.02). There was no difference in the risk of chronic GVHD, disease progression or relapse. Progression-free survival (PFS) (RR = 0.68; 95% CI 0.50-0.92; P = 0.01) and overall survival (OS) (RR = 0.63; 95% CI, 0.46-0.86; P = 0.004) were significantly better in the RTX cohort. Prior RTX therapy correlated with less acute GVHD, similar chronic GVHD, less TRM, better PFS and OS.

Rorschach variables relating to (I) aggression, (2) dependency, (3) object relations, (4) defenses, and (5) boundary disturbance were measured across a nonclinical (NC) and two clinical (borderline patients without self-mutilative behavior = N-BPD, and borderline patients with self-mutilative behaviors = SM-BPD) groups. Results demonstrated good discriminate ability (87%) between clinical and nonclinical protocols. Comparisons between N-BPD and SM-BPD groups revealed overall greater pathological scores for the SM-BPD group, specifically in dependency scores. Convergence with other studies and implications for future clinical and empirical work are discussed.

Failure to properly control centrosome number results in supernumerary centrosomes, which are frequently found in cancer cells. This presents a paradox: during mitosis, cells with more than two centrosomes are prone to multipolar mitoses and cell death, however, cancer cells possessing extra centrosomes usually divide successfully. One mechanism frequently utilized by cancer cells to escape death caused by multipolar mitoses is the clustering of supernumerary centrosomes into bipolar arrays. An understanding of the molecular mechanisms by which cancer cells can suppress multipolar mitoses is beginning to emerge. Here, we review what's currently known about centrosome clustering mechanisms and discuss potential strategies to target these mechanisms for the selective killing of cancer cells.

To explore molecular determinants differentiating pathogenic routes towards AD or cancer, we investigate the role of amyloid beta protein (A beta) on multiple tumor cell lines that are stably expressing luciferase (human glioblastoma U87; human breast adenocarcinoma MDA-MB231; and mouse melanoma B16F). Results: Quantification of the photons emitted from the MDA-MB231 or B16F cells revealed a significant inhibition of cell proliferation by the conditioning media (CM) derived from amyloid precursor protein (APP) over-expressing cells. The inhibition of U87 cells was observed only after the media was conditioned for longer than 2 days with APP over-expressing cells. Conclusion: Our results suggest that A beta plays an inhibitory role in tumor cell proliferation; this effect could depend on the type of tumor cells and amount of A beta.

TI A Cohort Study of p27 Localization in Colon Cancer, Body Mass Index, and Patient Survival SO CANCER EPIDEMIOLOGY BIOMARKERS & PREVENTION LA English DT Article ID ISLAND METHYLATOR PHENOTYPE; POPULATION-BASED SAMPLE; COLORECTAL-CANCER; MICROSATELLITE INSTABILITY; CELL-CYCLE; PROGNOSTIC-SIGNIFICANCE; LINE-1 HYPOMETHYLATION; SYNTHASE EXPRESSION; REGULATORY PROTEINS; INHIBITOR P27 AB Energy balance and the AKT pathway are important in colorectal cancer development and regulate p27 (cyclin-dependent kinase inhibitor-1B/CDKN1B/KIP1), which plays a role in preventing cell cycle progression. However, little is known on the clinical outcome or prognostic significance of p27 alterations in relation to patient body mass index (BMI). Among 630 colon cancers (stage I-IV) in two prospective cohort studies, we detected p27 alterations (cytoplasmic p27 localization or p27 loss) in 500 tumors (79%) by immunohistochemistry. The remaining 130 (21%) tumors were "p27-nuclear+." Cox proportional hazard models computed hazard ratios (HR) of deaths, adjusted for patient and tumoral characteristics, including p53, p21, cyclin D1, KRAS, BRAF, PIK3CA, cyclooxygenase-2, fatty acid synthase (FASN), beta-catenin, microsatellite instability (MSI), CpG island methylator phenotype (CIMP), and long interspersed nucleotide element-1 (LINE-1) hypomethylation. Compared with p27-nuclear+ patients, p27-altered patients experienced low colon cancer-specific [adjusted HR, 0.63; 95% confidence interval (95% CI), 0.42-0.94] and overall mortality (adjusted HR, 0.70; 95% CI, 0.51-0.95), independent of FASN, MSI, CIMP, LINE-1 methylation, and other potential confounders. The effect of p27 alteration on overall mortality significantly differed by BMI (P(interaction) = 0.013); adjusted HR (p27-altered versus p27-nuclear+ tumors) was 0.28 (95%, CI, 0.13-0.59) for BMI >= 30 kg/m(2), 0.67 (95% CI, 0.40-1.14) for BMI 25 to 29 kg/m(2), and 0.91 (95% CI, 0.57-1.46) for BMI <25 kg/m(2). Obesity was associated with inferior overall survival among p27-nuclear+ cases (adjusted HR, 3.07; 95% CI, 1.49-6.32; versus nonobese cases), but not among p27-altered cases (adjusted HR, 1.08). In conclusion, p27 alterations in colon cancer are associated with superior prognosis. Adverse prognostic effect of obesity seems limited to patients with nuclear p27 expression, suggesting a host-tumor interaction.

We prospectively investigated associations between dairy intakes and height growth. Methods: A cohort of 5,101 girls from throughout the United States completed annual surveys (1996-2001, 2003), providing height, weight, and past-year diet. At baseline, all were premenarchal, ages 9 years and above, with no serious medical conditions. We studied three outcomes: annual height growth, peak growth velocity, and adult height. Multivariate models estimated the effects of milk, cheese, yogurt, and energy on subsequent growth, adjusted for race/ethnicity, age, prior height, and body mass index. Other models studied fats and proteins. Results: Premenarchal girls who drank >3 servings per day of milk grew 0.11 in. (P = 0.02) more the following year than girls consuming <1 serving per day. Yogurt (+0.13 in./cup; P = 0.02), but not cheese or total calories, predicted height growth. In a separate model, dairy protein (+0.034 in./10 g; P < 0.001) predicted height growth. Larger peak velocities were seen among girls reporting, at baseline, more milk (>3 glasses per day versus <1; +0.14 in., P = 0.01), more yogurt (+0.17 in./cup, P = 0.02), and, in a separate model, more dairy protein (+0.039 in./10 g; P = 0.003). Baseline milk and dairy Protein predicted taller adults. Dairy protein was more important than dairy fat, for all outcomes. Nondairy animal protein and vegetable protein were never significant, nor were nondairy animal fat and vegetable fat. Conclusion: Of the foods/nutrients studied, dairy protein had the strongest association with height growth. These findings suggest that a factor in the nonlipid phase of milk, but not protein itself, has growth-promoting action in girls.

We performed an integrated, genome-wide analysis of copy-number changes and gene expression profiles in 90 tumors, including both sporadic and VHL disease-associated tumors, in hopes of identifying new therapeutic targets in ccRCC. We identified 14 regions of nonrandom copy-number change, including 7 regions of amplification (1q, 2q, 5q, 7q, 8q, 12p, and 20q) and 7 regions of deletion (1p, 3p, 4q, 6q, 8p, 9p, and 14q). An analysis aimed at identifying the relevant genes revealed VHL as one of three genes in the 3p deletion peak, CDKN2A and CDKN2B as the only genes in the 9p deletion peak, and MYC as the only gene in the 8q amplification peak. An integrated analysis to identify genes in amplification peaks that are consistently overexpressed among amplified samples confirmed MYC as a potential target of 8q amplification and identified candidate oncogenes in the other regions. A comparison of genomic profiles revealed that VHL disease-associated tumors are similar to a subgroup of sporadic tumors and thus more homogeneous overall. Sporadic tumors without evidence of biallelic VHL inactivation fell into two groups: one group with genomic profiles highly dissimilar to the majority of ccRCC and a second group with genomic profiles that are much more similar to tumors with biallelic inactivation of VHL.

TI Genetic variation in the vitamin C transporter, SLC23A2, modifies the risk of HPV16-associated head and neck cancer SO CARCINOGENESIS LA English DT Article ID SQUAMOUS-CELL CARCINOMA; HUMAN-PAPILLOMAVIRUS; CACO-2 CELLS; SVCT1; EXPRESSION; HUMAN-PAPILLOMAVIRUS-16; QUESTIONNAIRE; ASSOCIATION; VALIDATION; TOBACCO AB Human papillomavirus (HPV) type 16 infection is an etiologic factor in a subset of head and neck squamous cell carcinomas (HNSCC). It is unknown if host genetic susceptibility modifies the HPV16-HNSCC association. DNA samples collected as part of a Boston area case-control study of HNSCC were genotyped for single-nucleotide polymorphisms (SNPs) from the National Cancer Institute's SNP500Cancer database. Analysis of demographic, phenotypic and genotypic data for 319 HNSCC cases and 495 frequency-matched controls was performed using unconditional logistic regression. All reported P-values are two sided. We identified a polymorphism in the sodium-dependent vitamin C transporter SLC23A2 that modifies the risk of HNSCC associated with HPV16 infection. Among those with a wild-type allele at SLC23A2, the risk of HNSCC associated with HPV16-positive serology was 5.0 (95% confidence interval (CI) = 3.2-7.8). However, among those with a homozygous variant genotype, the risk of HNSCC associated with HPV16 was attenuated [odds ratio (OR) = 2.8; 95% CI = 1.2-6.2]. Further, when we tested whether genotype modified the interaction between citrus exposure, HPV16, and HNSCC, we found a dramatically increased risk of HNSCC for those with a wild-type SLC23A2 allele, HPV16-positive serology and high citrus intake (OR = 7.4; 95% CI = 3.6-15.1). These results suggest that SLC23A2 genetic variation alters HPV16-associated HNSCC while also highlighting the important role of citrus exposure in this disease.

Several negative studies on the role of homocysteine-lowering B-vitamin therapy in reducing the risk of atherothrombotic cardiovascular disease have dampened enthusiasm for this important field of research. In this review, we assess the present state of homocysteine research and suggest potential avenues that would help to clarify the purported link between the plasma homocysteine level and cardiovascular risk. We address several questions raised by the findings of various basic, epidemiological and clinical studies and attempt to construct a framework that we believe will allow us to address the fundamental unresolved issues in this controversial area, specifically focusing on the risk of coronary vascular disease and cardiac failure. This review should allow researchers to deconstruct this complex field into separate areas that, when addressed adequately, may lead to findings that elucidate the overall link between hyperhomocysteinemia and cardiovascular disease and allow the design of appropriate clinical trials.

While a large number of modified bases have been identified, many of the enzymes generating them still remain to be discovered. Recently, members of the 2-oxoglutarate-and iron(II)-dependent dioxygenase superfamily, which modify diverse substrates from small molecules to biopolymers, were predicted and subsequently confirmed to catalyze oxidative modification of bases in nucleic acids. Of these, two distinct families, namely the AlkB and the kinetoplastid base J binding proteins (JBP) catalyze in situ hydroxylation of bases in nucleic acids. Using sensitive computational analysis of sequences, structures and contextual information from genomic structure and protein domain architectures, we report five distinct families of 2-oxoglutarate-and iron(II)-dependent dioxygenase that we predict to be involved in nucleic acid modifications. Among the DNA-modifying families, we show that the dioxygenase domains of the kinetoplastid base J-binding proteins belong to a larger family that includes the Tet proteins, prototyped by the human oncogene Tet1, and proteins from basidiomycete fungi, chlorophyte algae, heterolobosean amoeboflagellates and bacteriophages. We present evidence that some of these proteins are likely to be involved in oxidative modification of the 5-methyl group of cytosine leading to the formation of 5-hydroxymethyl-cytosine. The Tet/JBP homologs from basidiomycete fungi such as Laccaria and Coprinopsis show large lineage-specific expansions and a tight linkage with genes encoding a novel and distinct family of predicted transposases, and a member of the Maelstrom-like HMG family. We propose that these fungal members are part of a mobile transposon. To the best of our knowledge, this is the first report of a eukaryotic transposable element that encodes its own DNA-modification enzyme with a potential regulatory role. Through a wider analysis of other poorly characterized DNA-modifying enzymes we also show that the phage Mu Mom-like proteins, which catalyze the N6-carbamoylmethylation of adenines, are also linked to diverse families of bacterial transposases, suggesting that DNA modification by transposable elements might have a more general presence than previously appreciated. Among the other families of 2-oxoglutarate-and iron(II)-dependent dioxygenases identified in this study, one which is found in algae, is predicted to mainly comprise of RNA-modifying enzymes and shows a striking diversity in protein domain architectures suggesting the presence of RNA modifications with possibly unique adaptive roles. The results presented here are likely to provide the means for future investigation of unexpected epigenetic modifications, such as hydroxymethyl cytosine, that could profoundly impact our understanding of gene regulation and processes such as DNA demethylation.

Recently, we determined that induction of antigen-specific T cell tolerance results in impaired cdk2 activity leading to enhanced Smad3 transactivation, upregulation of p15 and blockade of cell cycle progression. Here we report that pharmacologic inhibition of cdk2 with (R)-roscovitine blocked expansion of alloreactive T cells in vitro and in vivo and protected from lethal acute GvHD. In addition to inhibiting alloreactive T cell responses, (R)-roscovitine prevented TNF alpha-mediated activation of NF kappa B pathway, which is involved in the inflammatory process leading to the development of GvHD. The combined anti-proliferative and anti-inflammatory properties of (R)-roscovitine make it an attractive treatment modality toward control of GvHD.

Vacuolating cytotoxin secreted by H. pylori has turned out to be a potent immunomodulatory toxin, but the signal transduction pathways involved has not been studied in macrophages. We observed in this study that vacA-deficient H. pylori induced significantly higher expression of integrin-linked kinase (ILK) and endothelial nitric oxygen synthase (eNOS), and significantly more production of reactive oxygen species (ROS) in monocyte/macrophage-like U937 cells, as compared with isogenic vacA(+) H. pylori. The expression of eNOS mRNA in U937 cells overexpressing ILK was markedly increased compared with those transfected with empty vectors. Thus, vacA-deficient H. pylori appears to upregulate ILK expression, which modulates the expression of eNOS and as a result, stimulates the production of ROS. It is VacA that prevents such a process by inhibiting ILK expression, helping H. pylori escape host immunoreaction. This mechanism explains, at least in part, persistent infection of H. pylori in the stomach. Cellular & Molecular Immunology. 2009;6(3):191-197.

Absent in normal lungs, these sonographic findings become prominent as interstitia and alveoli fill with fluid. Characterization of the dynamics of B-lines, specifically their rate of disappearance as volume is removed, has not been previously, described. In this study, we describe the dynamics of B-fine resolution in patients undergoing hemodialysis. Methods: Patients undergoing hemodialysis underwent three chest ultrasound examinations: before, at the midpoint, and after dialysis. We followed a previously, described chest ultrasound protocol that counts the number of B-lines visualized in 28 lung zones. Baseline demographics, assessment of ejection fraction, time elapsed, net volume of fluid removed, and subjective degree of shortness of breath were recorded for each patient. Results: Forty of 45 patients completed full dialysis runs and bad all three lung scans performed; 6 of 40 patients had zero or one B-line predialysis, and none of these 6 patients gained B-lines during dialysis. Thirty-four of 40 patients had statistically, significant reductions in the number of B-lines from predialysis to, the midpoint scan and from predialysis to postdialysis with a p value < 0.001. There was no association between subjective dyspnea scores and number of B-lines removed. Conclusions. B-line resolution appears to occur real-time its fluid is removed from the body, and this change was statistically significant. These data support thoracic ultrasound as a useful method for evaluating real-time changes in EVLW and in assessing a patient's physiologic response to the removal of fluid.

The authors reported that black and Hispanic children were provided substandard care at hospital discharge compared to white children. The purpose of the present analysis was to reexamine this important issue in a large multicenter study. Methods: A cohort study of 1,232 children and adults hospitalized with a physician diagnosis of acute asthma at 30 hospitals in 22 US states was used. Results: The cohort included 562 children (age range, 2 to 17 years; 39% white; 42% black; and 19% Hispanic) and 670 adults (age range, 18 to 54 years; 44% white; 44% black; and 12% Hispanic). There were no significant racial/ethnic differences in the choice of inpatient medications or length of stay among either children or adults. At hospital discharge, Hispanic children were less likely to receive an asthma action plan (37%) compared to white children (60%) or black children (63%; p < 0.001). Multivariate adjustment for eight variables (including socioeconomic status, hospital admissions for asthma in the past year, medication use prior to presentation, physical examination findings, and hospital admission location) attenuated the statistical significance of this association (odds ratio, 0.5; 95% confidence interval, 0.1 to 2.5). Conclusions: We did not identify racial/ethnic disparities in the inpatient treatment and outcomes for children or adults with acute asthma. At hospital discharge, Hispanic children were less likely to receive an asthma action plan compared to white or black children, possibly due to language or socioeconomic differences.

It has been usually described in the setting of congenital defects such as atrial septal defect, ventricular septal defect, and, more rarely, isolated persistent ductus arteriosus. Functional and structural evaluation of such patients can currently be performed noninvasively with the use of cardiae CT scanning and/or MRI. The optimal management of symptomatic patients remains unknown. We report a case of extrinsic compression of the LMCA in a symptomatic patient with Eisenmenger syndrome who underwent unprotected LMCA stent implantation. We also performed a literature review of the reported cases concerning patients treated with LMCA stent implantation for the management of this condition.

To minimize safety concerns and imaging artifacts in MR-guided interventional electrophysiology (EP), we aimed at developing a setup including catheters for ablation therapy based on carbon technology. Methods and Results-The setup, including a steerable carbon catheter, was tested for safety, image distortion, and feasibility of diagnostic EP studies and radiofrequency ablation at 1.5 T. MRI was performed in 3 different 1.5-T whole-body scanners using various receive coils and pulse sequences. To assess unintentional heating of the catheters by radiofrequency pulses of the MR scanner in vitro, a fluoroptic thermometry system was used to record heating at the catheter tip. Programmed stimulation and ablation therapy was performed in 8 pigs. There was no significant heating of the carbon catheters while using short, repetitive radiofrequency pulses from the MR system. Because there was no image distortion when using the carbon catheters, exact targeting of the lesion sites was possible. Both atrial and ventricular radiofrequency ablation procedures including atrioventricular node modulation were performed successfully in the scanner. Potential complications such as pericardial effusion after intentional perforation of the right ventricular free wall during ablation could be monitored in real time as well. Conclusion-We describe a newly developed EP technology for interventional electrophysiology based on carbon catheters. The feasibility of this approach was demonstrated by safety testing and performing EP studies and ablation therapy with carbon catheters in the MRI environment.

In the family-based Framingham Heart Study, we investigated heritability and candidate gene associations of systemic inflammatory biomarkers. Methods and Results-In offspring participants (n = 3710), we examined 11 inflammatory biomarkers (CD40 ligand, C-reactive protein, intercellular adhesion molecule-1, interleukin-6, urinary isoprostanes, monocyte chemoattractant protein-1, myeloperoxidase, P-selectin, tumor necrosis factor-alpha, tumor necrosis factor receptor II, fibrinogen). Heritability and bivariate genetic and environmental correlations were assessed by Sequential Oligogenic Linkage Analysis routines in 1012 family members. We examined 1943 tagging single-nucleotide polymorphisms in 233 inflammatory pathway genes with >= 5 minor allele carriers using a general genetic linear model. Clinical correlates explained 2.4% (CD40 ligand) to 28.5% (C-reactive protein) of the variability in inflammatory biomarkers. Estimated heritability ranged from 10.9% (isoprostanes) to 44.8% (P-selectin). Most correlations between biomarkers were weak although statistically significant. A total of 45 single-nucleotide polymorphism-biomarker associations met the q-value threshold of 0.25. Novel top single-nucleotide polymorphisms were observed in ICAM1 gene in relation to intercellular adhesion molecule-1 concentrations (rs1799969, P = 1.32 x 10(-8)) and MPO in relation to myeloperoxidase (rs28730837, P = 1.9 x 10(-5)). Lowest P values for trans-acting single-nucleotide polymorphisms were observed for APCS with monocyte chemoattractant protein-1 concentrations (rs1374486, P = 1.01 x 10(-7)) and confirmed for IL6R with interleukin-6 concentrations (rs8192284, P = 3.36 x 10(-5)). Novel potential candidates (APCS, MPO) need to be replicated. Conclusions-Our community-based data support the relevance of clinical and genetic factors for explaining variation in inflammatory biomarker traits. (Circ Cardiovasc Genet. 2009; 2: 229-237.)

Whether these same SNPs associate with lipids in a broader range of ethnicities is unknown. Methods and Results-We genotyped index SNPs at 19 loci in the Third United States National Health and Nutrition Examination Survey (n = 7159), a population-based probability sample of the United States comprised primarily of non-Hispanic blacks, Mexican Americans, and non-Hispanic whites. We constructed ethnic-specific residual blood lipid levels after adjusting for age and gender. Ethnic-specific linear regression was used to test the association of genotype with blood lipids. To summarize the statistical evidence across 3 racial groups, we conducted a fixed-effects variance-weighted meta-analysis. After exclusions, there were 1627 non-Hispanic blacks, 1659 Mexican Americans, and 2230 non-Hispanic whites. At 5 loci (1p13 near CELSR2/PSRC1/SORT1, HMGCR, CETP, LPL, and APOA5), the index SNP was associated with low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, or triglycerides in all 3 ethnic groups. At the remaining loci, there was mixed evidence by ethnic group. In meta-analysis, we found that, at 14 of the 19 loci, SNPs exceeded a nominal P < 0.05. Conclusions-At 5 loci including the recently discovered region on 1p13 near CELSR2/PSRC1/SORT1, the same SNP discovered in whites associates with blood lipids in non-Hispanic blacks and Mexican Americans. For the remaining loci, fine mapping and resequencing will be required to definitively evaluate the relevance of each locus in individuals of African and Hispanic ancestries.

Data from the paclitaxel-eluting stent (PES) trials and registries were pooled to assess PES benefits relative to advancing patient age, including comparison with bare-metal stents. Methods and Results - Data from 5 randomized trials (2271 patients with PES, 1397 patients with bare-metal stents) and from 2 postmarket registries (7492 patients with PES) were pooled separately. Each dataset was stratified into age groups: <60, 60 to 70, and >70 years. At baseline, patients aged >70 years in both datasets had significantly more adverse characteristics than younger patients. Through 5 years, trial data showed that patients aged >70 years had higher death rates, but comparable rates of myocardial infarction, stent thrombosis, and target lesion revascularization with younger patients. Compared with patients with bare-metal stents, patients with PES aged >70 years had comparable rates of death, myocardial infarction, and stent thrombosis but a significantly lower target lesion revascularization rate (22.2 versus 10.2, P < 0.001). These findings were echoed in the registry data through 2 years that showed that PES patients aged >70 years had significantly higher death rates, but lower myocardial infarction, stent thrombosis, and target lesion revascularization rates, compared with younger patients. Although the mortality rates of patients aged >70 years were higher than those of younger patients, they were comparable with those of age- and gender-matched norms in the general population. Conclusions - This analysis of almost 10 000 patients demonstrated that percutaneous coronary intervention with PES is a safe and an effective treatment option that should not be withheld based on age.

Dnmt3b can induce colon tumor in mice with methylation in specific CpG islands. We hypothesized that cellular DNMT3B level might influence the occurrence of widespread CpG island methylation (i.e., the CpG island methylator phenotype, CIMP) in colon cancer. Experimental Design: Utilizing 765 colorectal cancers in two cohort studies, we detected DNMT3B expression in 116 (15%) tumors by immunohistochemistry. We assessed microsatellite instability, quantified DNA methylation in repetitive long interspersed nucleotide element-1 (LINE-1) by Pyrosequencing, eight CIMP-specific promoters [CACNA1G, CDKN2A (p16), CRABP1, IGF2, MLH1, NEUROG1, RUNX3, and SOCS1], and eight other CpG islands (CHFR, HIC1, IGFBP3, MGMT, MINT1, MINT31, p14, and WRN) by real-time PCR (MethyLight). Results: Tumoral DNMT3B overexpression was significantly associated with CIMP-high [>= 6/8 methylated CIMP-specific promoters; odds ratio (OR), 3.34; 95% confidence interval, 2.11-5.29; P < 0.0001]. The relations between DNMT3B and methylation in 16 individual CpG islands varied substantially (OR, 0.80-2.96), suggesting variable locus-to-locus specificities of DNMT3B activity. DNMT3B expression was not significantly related with LINE-1 hypomethylation. In multivariate logistic regression, the significant relation between DNMT3B and CIMP-high persisted (OR, 2.39; 95% confidence interval, 1.11-5.14; P = 0.026) after adjusting for clinical and other molecular features, including p53, beta-catenin, LINE-1, microsatellite instability, KRAS, PIK3CA, and BRAF DNMT3B expression was unrelated with patient outcome, survival, or prognosis. Conclusions: Tumoral DNMT3B overexpression is associated with CIMP-high in colorectal cancer. Our data support a possible role of DNMT3B in nonrandom de novo CpG island methylation leading to colorectal cancer.

Here, we investigated the potential role of FOXA1 in human thyroid carcinomas. Experimental Design: We examined the level of FOXA1 expression and gene copy number by immunohistochemistry and fluorescence in situ hybridization, respectively, in a cohort of benign and malignant thyroid tumors. In addition, we examined the role of FOXA1 in the proliferation of an undifferentiated thyroid carcinoma cell line by short hairpin RNA-mediated silencing. Results: We show that FOXA1 is overexpressed in human anaplastic thyroid carcinomas (ATC). In addition, we identify FOXA1 DNA copy number gain within the 14q21.1 locus in both an ATC cell line and human ATC cases. Silencing of FOXA1 in an ATC cell line causes G(1) growth arrest and reduction of cell proliferation. Moreover, we observe a potential link between FOXA1 and the cell cycle machinery by identifying p27(kip1) up-regulation on FOXA1 silencing. Conclusions: FOXA1 is overexpressed in aggressive thyroid cancers and involved in cell cycle progression in an ATC cell line. Therefore, FOXA1 may be an important oncogene in thyroid tumorigenesis and a potential new therapeutic target for the treatment of anaplastic thyroid cancers.

TI Quality of Reporting of Serious Adverse Drug Events to an Institutional Review Board: A Case Study with the Novel Cancer Agent, Imatinib Mesylate SO CLINICAL CANCER RESEARCH LA English DT Article ID RADAR PROJECT; CARDIOTOXICITY; LEUKEMIA; HEAD AB Purpose: Serious adverse drug event (sADE) reporting to Institutional Review Boards (IRB) is essential to ensure pharmaceutical safety. However, the quality of these reports has not been studied. Safety reports are especially important for cancer drugs that receive accelerated Food and Drug Administration approval, like imatinib, as preapproval experience with these drugs is limited. We evaluated the quality, accuracy, and completeness of sADE reports submitted to an IRB. Experimental Design: sADE reports submitted to an IRB from 14 clinical trials with imatinib were reviewed. Structured case report forms, containing detailed clinical data fields and a validated causality assessment instrument, were developed. Two forms were generated for each ADE, the first populated with data abstracted from the IRB reports, and the second populated with data from the corresponding clinical record. Completeness and causality assessments were evaluated for each of the two sources, and then compared. Accuracy (concordance between sources) was also assessed. Results: Of 115 sADEs reported for 177 cancer patients to the IRB, overall completeness of adverse event descriptions was 2.4-fold greater for structured case report forms populated with information from the clinical record versus the corresponding forms from IRB reports (95.0% versus 40.3%, P < 0.05). Information supporting causality assessments was recorded 3.5-fold more often in primary data sources versus IRB adverse event descriptions (93% versus 26%, P < 0.05). Some key clinical information was discrepant between the two sources. Conclusions: The use of structured syndrome-specific case report forms could enhance the quality of reporting to IRBs, thereby improving the safety of pharmaceuticals administered to cancer patients.

TI Developing Multiplexed Assays for Troponin I and Interleukin-33 in Plasma by Peptide Immunoaffinity Enrichment and Targeted Mass Spectrometry SO CLINICAL CHEMISTRY LA English DT Article ID HYPERTROPHIC OBSTRUCTIVE CARDIOMYOPATHY; MYOCARDIAL-INFARCTION; BIOMARKER DISCOVERY; SERUM; QUANTIFICATION; PROTEIN; CHROMATOGRAPHY; QUANTITATION; PERFORMANCE; VALIDATION AB BACKGROUND: Protein biomarker candidates from discovery proteomics must be quantitatively verified in patient samples before they can progress to clinical validation. Here we demonstrate that Peptide immunoaffinity enrichment coupled with stable isotope dilution mass spectrometry (SISCAPA-MRM) can be used to configure assays with performance suitable for candidate biomarker verification. As proof of principle, we configured SISCAPA assays for troponin I (cTnI), an established biomarker of cardiac injury, and interleukin 33 (IL-33), an emerging immunological and cardiovascular marker for which robust immunoassays are currently not available. METHODS: We configured individual and multiplexed assays in which peptides were enriched from digested human plasma using antipeptide antibodies. Assay performance was established using response curves for peptides and proteins spiked into normal plasma. We quantified proteins using labeled peptides as internal standards, and we measured levels of cTnI in patients who underwent a planned myocardial infarction for hypertrophic obstructive cardiomyopathy. RESULTS: Measurement of cTnI and IL-33 proteins from trypsin-digested plasma was linear from 1.5 to 5000 mu g/L, with imprecision < 13% for both proteins, processed individually or multiplexed. Results correlated well (R = 0.89) with a commercial immunoassay. CONCLUSIONS: We used an established biomarker of cardiac injury and an emerging biomarker to demonstrate how SISCAPA can detect and quantify changes in concentration of proteins present at 1-10 mu g/L in plasma. Our results demonstrate that these assays can be multiplexed and retain the necessary precision, reproducibility, and sensitivity to be applied to new and uncharacterized candidate biomarkers for verification of low-abundance proteins in blood.

The incidence of cryptococcal disease among solid-organ transplant recipients has remained unchanged; however, patients are less likely to present with central nervous system or disseminated disease and are more likely to have cryptococcosis limited to the lungs. Additionally, lipid formulations of amphotericin B are now used more frequently, whereas their use in combination with flucytosine has decreased. The overall mortality of cryptococcosis has significantly improved in the current era. Renal failure remains associated with poor outcome, whereas use of lipid formulations of amphotericin B is associated with a higher survival rate. Despite rare infectious complication, certain peculiar attributes of cryptococcal disease in hematopoietic stem cell recipients and tissue transplant recipients warrant recognition.

Although patients with mCRC have benefited considerably from recent therapeutic advances, the use of more complex treatment regimens has inevitably resulted in an increase in treatment-related toxicities. This can ultimately lead to dose reductions, delays, or discontinuation of therapy, which may negatively affect efficacy outcomes. Early identification and treatment of toxicities often can allow treatment to continue as planned or at a lower dose, if required. The oncology nurse is ideally positioned to assist with the timely recognition and management of side effects. This allows therapy to be continued on schedule and at the appropriate dose, enabling patients to achieve a better clinical outcome and maintain or improve their quality of life.

Dasatinib demonstrated efficacy with a well-tolerated safety profile in all phases of CML and Ph+ ALL, which led to its 2006 approval by the U.S. Food and Drug Administration for clinical use. However, although most adverse events are grade 1 or 2, a number of adverse events require management and monitoring to ensure that patients can continue receiving the treatment.

The authors sought to compare symptoms, depression, and quality of life in patients with ESRD and those with CKD. Design, setting, participants, & measurements: Patients with ESRD and subjects with advanced CKD were enrolled. Patients' symptoms, depression, and quality of life were assessed using the Dialysis Symptom Index (DSI), Patient Health Questionnaire-9 (PHQ-9), and Short Form 36 (SF-36), respectively, and these health domains were compared between patient groups. Results: Ninety patients with ESRD and 87 with CKD were enrolled. There were no differences in the overall number of symptoms or in the total DSI symptom-severity score. Median scores on the PHQ-9 were similar, as was the proportion of patients with PHQ-9 scores >9. SF-36 Physical Component Summary scores were comparable, as were SF-36 Mental Component Summary scores. Conclusions: The burden of symptoms, prevalence of depression, and low quality of life are comparable in patients with ESRD and advanced CKD. Given the widely recognized impairments in these domains in ESRD, findings of this study underscore the substantial decrements in the physical and psychologic well-being of patients with CKD.

Neuropsychological deficits that have been identified in adults and children with bipolar disorder include impairments in executive functions, declarative memory, attentional processes, and possibly working memory. Structural and functional magnetic resonance imaging and magnetic resonance spectroscopy studies of adults and children with bipolar disorder also indicate abnormalities in regions thought to underlie these neuropsychological deficits, including the basal ganglia, amygdala, and dorsolateral, orbitofrontal, and anterior cingulate cortices. Study of this area is made challenging by the heterogeneity of bipolar disorder, the heterogeneity of neuropsychological deficits among groups of patients with different clinical characteristics, the lack of specificity of neurocognitive deficits for bipolar disorder, and difficulty ascertaining whether deficits are inherent in the disorder, predate the disorder, or are influenced by mood state, course, treatment, and comorbidity with other disorders. In this review, we integrate the literature on neuropsychological functioning and neuroimaging in both children and adults with bipolar disorder, propose a nascent integrative model of cognitive function in bipolar disorder, and make suggestions for future studies and model development..

TI Retention of Under-represented Minorities in Drug Abuse Treatment Studies SO CLINICAL TRIALS LA English DT Article ID CLINICAL-TRIALS-NETWORK; SUBSTANCE-ABUSE; BUPRENORPHINE-NALOXONE; TREATMENT PROGRAMS; BREAST-CANCER; STRATEGIES; DETOXIFICATION; PARTICIPANTS; RECRUITMENT; INCENTIVES AB Background Differential attrition by minority participants can be as limiting to interpreting final results as poor initial recruitment of minority participants. This is especially important in drug abuse treatment studies, as minorities are over-represented in substance abuse clinical treatment programs. Purpose The specific aims of this secondary data analysis were to: (1) determine if there are differences in study retention rates by race/ethnicity and age, and (2) explore other client characteristics, as well as protocol and treatment program factors, that could account for differential retention rates. Methods We conducted a secondary analysis using data from 1737 participants in the first six clinical trials whose databases were locked in the NIDA Clinical Trials Network. Protocol level characteristics were also abstracted from these studies, and we used data from a study which assessed characteristics of community treatment programs that participated in these studies. Logistic regression was used to study the effect on retention of: client, protocol, and program characteristics. Results In the model of client characteristics, a significant age by race/ethnicity interaction term was detected based on a threshold of 0.1, with younger African Americans having the lowest odds of retention. Primary drug of abuse was also a significant factor in determining study retention, with heroin, methadone, and opiate users having the greatest odds of retention and polydrug users the lowest. Similar analyses testing treatment program characteristics found that only the presence of HIV risk screening and decreasing levels of female admissions (as a percent of total admissions) were related to study retention. In our final model, there was an effect of age, but not race/ethnicity, with younger participants having lower odds of retention. A multivariable model including protocol variables could not be developed due to the high correlation among protocol variables. Limitations We excluded those of multi-race/ethnicity and those from minority groups other than Hispanic or African American due to small numbers. Additionally, only three therapy types were represented among the six studies. Some potential variables that would influence retention, such as client housing, and client comorbidities, the race/ethnicity and gender of the staff who conducted study follow-up assessments, and reasons for loss to follow-up, were not collected by the CTN. Conclusions Although in our client model older African Americans and Caucasians had the greatest odds of retention and younger African Americans the lowest, in our final model, only age was significantly related to study retention. Additionally, primary drug of abuse, having HIV risk screening as a program benefit, and lower percentages of female admissions were significantly related to study retention. Efforts should be made to increase the study retention of younger participants to improve the validity and generalizability of drug abuse treatment study results.

Purpose To present the design, history, and analytic challenges of the Breast International Group (BIG) 1-98 trial: an international, multicenter, randomized, double-blind, phase-III study comparing the aromatase inhibitor letrozole with tamoxifen in this clinical setting. Methods From 1998-2003, BIG 1-98 enrolled 8028 women to receive monotherapy with either tamoxifen or letrozole for 5 years, or sequential therapy of 2 years of one agent followed by 3 years of the other. Randomization to one of four treatment groups permitted two complementary analyses to be conducted several years apart. The first, reported in 2005, provided a head-to-head comparison of letrozole versus tamoxifen. Statistical power was increased by an enriched design, which included patients who were assigned sequential treatments until the time of the treatment switch. The second, reported in late 2008, used a conditional landmark approach to test the hypothesis that switching endocrine agents at approximately 2 years from randomization for patients who are disease-free is superior to continuing with the original agent. Results The 2005 analysis showed the superiority of letrozole compared with tamoxifen. The patients who were assigned tamoxifen alone were unblinded and offered the opportunity to switch to letrozole. Results from other trials increased the clinical relevance about whether or not to start treatment with letrozole or tamoxifen, and analysis plans were expanded to evaluate sequential versus single-agent strategies from randomization. Conclusions BIG 1-98 is an example of an enriched design, involving complementary analyses addressing different questions several years apart, and subject to evolving analytic plans influenced by new data that emerge over time.

These infections result in serious morbidity, can be life threatening, and are expensive to manage. Early suspicion of Candida infection and the use of timely and proper antifungal treatment can improve outcome. Although treatment of documented, deep-seated Candida infections in nonneutropenic patients has been studied extensively, guidelines for the management of suspected but undocumented cases of invasive Candida infections in critically ill patients have not been clearly established. Future work should focus on better delineation of the sector of critically ill patients who have suspected invasive Candida infection and who could benefit from the use of empiric antifungal therapy, and on the investigation of novel approaches for the potential salvage of devices infected with Candida species.

Analyses were conducted on 16 821 adults, using data from the National Health and Nutrition Examination Survey-III. Age- and multivariate-adjusted negative binomial regressions were used to explore the relation of socioeconomic factors, region of residence, gender, and foreign birth with the number of missing teeth. Effect modification by race/ethnicity was assessed by the inclusion of interaction terms. In multivariate-adjusted analyses, non-Hispanic White people with 9-12 years of education exhibited 71% higher mean number of missing teeth than those with > 12 years of education [incidence rate ratio (IRR) = 1.71, 95% confidence interval (CI): 1.52-1.92]. Education was unrelated to the number of teeth among non-Hispanic Black people (IRR = 1.16; 95% CI: 1.00-1.35) or Mexican-Americans (IRR = 1.10, 95% CI: 0.93-1.31). The poorest White people exhibited 39% more missing teeth, on average, than the most affluent White people, but no association between poverty and number of teeth was observed among Black or Mexican-American people. The associations between socioeconomic factors and tooth loss vary across race/ethnicity. This suggests that the health benefits associated with high socioeconomic status are not equally shared across racial/ethnic groups.

In this scenario, spectral methods are extremely promising as they provide a natural library of tools for shape analysis, intrinsically defined by the shape itself. In particular, the eigenfunctions of the Laplace-Beltrami operator yield a set of real-valued functions that provide interesting insights in the structure and morphology of the shape. In this paper, we first analyze different discretizations of the Laplace-Beltrami operator (geometric Laplacians, linear and cubic FEM operators) in terms of the correctness of their eigenfunctions with respect to the continuous case. We then present the family of segmentations induced by the nodal sets of the eigenfunctions, discussing its meaningfulness for shape understanding. (C) 2009 Elsevier Ltd. All rights reserved.

Design: This is a secondary analysis of data from two randomized trials. Baseline clinical variables collected within 24 hours of enrollment were modeled as predictors of hospital mortality using logistic regression and bootstrap resampling to arrive at a parsimonious model. We constructed a point score based on regression coefficients. Setting. Medical centers participating in the Acute Respiratory Distress Syndrome Clinical Trials Network (ARDSnet). Patients. Model development: 414 patients with nontraumatic ALI participating in the low tidal volume arm of the ARDSnet Acute Respiratory Management in ARDS study. Model validation: 459 patients participating in the ARDSnet Assessment of Low tidal Volume and elevated End-expiratory volume to Obviate Lung Injury study. Model Validation: 459 patients participating in the ARDSnet Assessment of Low tidal Volume and elevated End-expiratory volume to Obviate Lung Injury trial. Interventions: None. Measurements and Main Results. Variables comprising the prognostic model were hematocrit <26% (1 point), bilirubin >= 2 mg/dL (1 point), fluid balance >2.5 L positive (1 point), and age (1 point for age 40-64 years, 2 points for age >= 65 years). Predicted mortality (95% confidence interval) for 0, 1, 2, 3, and 4+ point totals was 8% (5% to 14%), 17% (12% to 23%), 31% (26% to 37%), 51% (43% to 58%), and 70% (58% to 80%), respectively. There was an excellent agreement between predicted and observed mortality in the validation cohort. Observed mortality for 0, 1, 2, 3, and 4+ point totals in the validation cohort was 12%, 16%, 28%, 47%, and 67%, respectively. Compared with the Acute Physiology Assessment and Chronic Health Evaluation III score, areas under the receiver operating characteristic curve for the point score were greater in the development cohort (0.72 vs. 0.67, p = 0.09) and lower in the validation cohort (0.68 vs. 0.75, p = 0.03). Conclusions: Mortality in patients with ALI can be predicted using an index of four readily available clinical variables with good calibration. This index may help inform prognostic discussions, but validation in nonclinical trial populations is necessary before widespread use.

Because the cells are seeded in a high density grid of cell-sized microwells, thousands of individual cells can be tracked and imaged through manipulations as extreme as freezing or drying. Unlike flow cytometry, measurements can be made at multiple time points for the same set of cells. Unlike conventional image cytometry, image analysis is greatly simplified by arranging the cells in a spatially defined pattern and physically separating them from one another. To demonstrate the utility of microwell array cytometry in the field of biopreservation, we have used it to investigate the role of mitochondrial membrane potential in the cryopreservation of primary hepatocytes. Even with optimized cryopreservation protocols, the stress of freezing almost always leads to dysfunction or death in part of the cell population. To a large extent, cell fate is dominated by the stochastic nature of ice crystal nucleation, membrane rupture, and other biophysical processes, but natural variation in the initial cell population almost certainly plays an important and under-studied role. Understanding why some cells in a population are more likely to survive preservation will be invaluable for the development of new approaches to improve preservation yields. For this paper, primary hepatocytes were seeded in microwell array devices, imaged using the mitochondrial dyes Rh123 or JC-1, cryopreserved for up to a week, rapidly thawed, and checked for viability after a short recovery period. Cells with a high mitochondrial membrane potential before freezing were significantly less likely to survive the freezing process, though the difference in short term viability was fairly small. The results demonstrate that intrinsic cell factors do play an important role in cryopreservation survival, even in the short term where extrinsic biophysical factors would be expected to dominate. We believe that microwell array cytometry will be an important tool for a wide range of studies in biopreservation and stress biology. (C) 2009 Elsevier Inc. All rights reserved.

We report a study on the protective effects of intracellular and extracellular sugars during bovine sperm desiccation and the supplemental effects of the addition of an antioxidant (catalase) or a chelator (desferal). The goal of the study was to preserve mammalian sperm in a partially or completely desiccated state. Sperm loaded intracellularly with two different types of sugars, trehalose or sucrose, were dried with and without catalase and desferal and evaluated for motility and membrane integrity immediately after rehydration. Intracellular sugars were loaded using ATP induced poration. Drying was performed in desiccator boxes maintained at 11% relative humidity (RH). Results indicated that sperm exhibited improved desiccation tolerance if they were loaded with either intracellular trehalose or sucrose. Survival was further enhanced by the addition of 1 mM desferal to the desiccation buffer. Though sperm motility after drying to low dry basis water fractions (DBWF) did not show significant improvement under any of the tested conditions, there was an increase in the sperm membrane integrity that could be retained after partial desiccation through the use of intracellular sugars and desferal.

Yet few programs train faculty in mentoring skills. We describe outcomes from the first two faculty cohorts who completed a Mentor Development Program (MDP) at UCSF. Eligibility includes having dedicated research time, expertise in a scientific area and a desire to be a lead research mentor. A post-MDP survey measured the program's impact on enhancement of five key mentoring skills, change in the Mentors-in-Training (MIT) self-rated importance of being a mentor to their career satisfaction, and overall confidence in their mentoring skills. Since 2007, 29 MITs participated in and 26 completed the MDP. Only 15% of the MITs reported any previous mentor training. Overall, 96% of MITs felt that participation in the MDP helped them to become better mentors. A majority reported a significant increase in confidence in mentoring skills and most reported an increased understanding of important mentoring issues at UCSF. MITs reported increased confidence in overall and specific mentoring skills after completion of the MDP. The MDP can serve as a model for other institutions to develop the next generation of clinical-translational research mentors.

Among Cambodian refugees attending a psychiatric clinic, we found that having a nightmare was strongly associated with having PTSD (chi(2) = 61.7, P < 0.001, odds ratio = 126); that nightmares caused much distress upon awakening, including panic attacks, fear of bodily dysfunction, flashbacks and difficulty returning to sleep; that nightmare content was frequently related to traumatic events; that nightmares resulted in a decrease in the sense of "concentric ontology security" (i.e., in an increased sense of physical and spiritual vulnerability in a culture that conceives of the self in terms of concentric, protective layers), including fears of being attacked by ghosts; and that nightmares frequently led to the performance of specific practices and rituals aiming to extrude and repel attacking forces and to create "protective layers." Cases are presented to illustrate these findings. The Discussion considers some treatment implications of the study. C1 [Hinton, D. E.; Pollack, M.

It is partly responsible for guiding immunologic development within the infant. Given the sharp escalation in immunologic diseases such as allergy and inflammatory bowel disease (IBD), this microbial-host interaction has become the focus of intense interest. DNA-based detection techniques have allowed increased identification of specific microbes involved in this symbiosis. Recent findings Epidemiologic studies have demonstrated a link between allergic diseases and alterations in the colonizing flora of infants. Concurrently, other work has demonstrated that interactions between gut flora and the intestinal epithelium seem to be central to the pathogenesis of IBD. In both allergy and IBD, certain bacteria seem to provide beneficial, protective effects via immune modulation. Summary There is a complex interaction between the bacteria within the developing gut and the immune system of the host. Colonization of the neonatal gut represents a critical window in this process. It appears clear that disruption within this flora has long-term health consequences as diverse as eczema, allergic rhinitis, and IBD. Guided establishment of specific species within the flora may reduce the incidence of these diseases.

Yet we are only now beginning to understand where and how B cells acquire antigen. Recent studies identify multiple pathways by which lymph-borne antigens enter the B cell follicles of LNs. Size is a major factor as particulate antigens and large IC are bound by subcapsular sinus macrophages. By contrast, small antigens (under 70 kDa) are rapidly channeled into follicles via conduits secreted by fibroblastic reticular cells (FRC). Interestingly, the conduits not only deliver antigen to follicular dendritic cells (FDC) but also provide a rich source of B cell chemokine, that is, CXCL-13. Thus, the follicular conduits provide an 'antigen highway' for B cells trafficking within the LN.

However, this has been difficult to prove, leading to a great deal of controversy within the field. Recent studies on mice and humans with genetic defects in insulin signaling have allowed us, for the first time, to dissect which features of the metabolic syndrome can be caused by insulin resistance. Recent findings Liver insulin receptor knockout mice show that hepatic insulin resistance can produce hyperglycemia, increased apolipoprotein B secretion and atherosclerosis, and increased biliary cholesterol secretion and cholesterol gallstones. Many of these changes may be due to disinhibition of the transcription factor, forkhead box O1. Yet, neither liver insulin receptor knockout mice nor humans with insulin receptor mutations develop the hypertriglyceridemia or hepatic steatosis associated with the metabolic syndrome. Summary These data point to a central role for insulin resistance in the pathogenesis of the metabolic syndrome, as hyperglycemia, atherosclerosis, and cholesterol gallstones can all be caused by insulin resistance. However, hypertriglyceridemia and hepatic steatosis are not due directly to insulin resistance and should be considered pathogenically distinct features of the metabolic syndrome.

Adult research suggests that TTM is accompanied by significant depression, anxiety, and functional impairment. The purpose of this study is to examine the occurrence of depression and anxiety in a relatively large sample of youth with TTM and the extent to which these symptoms mediate the relationship between TTM severity and associated impairment. Methods: The study utilized data front the Child and Adolescent Trichotillomania Impact Project (CA-TIP), an internet-based sample of 133 youth aged 10-17 (inclusive) with TTM. Results: Over 45% of children with TTM endorsed depressive symptoms and 40% endorsed anxiety symptoms in excess of one standard deviation (SD) above published community norms. More remarkably, 25% of our sample reported depressive and 20% reported anxiety symptoms in excess of 2 SD above these norms. Older participants reported more symptoms of depression and anxiety than younger ones; age of onset (children with later onset), but not duration of illness, was predictive of higher reports of both depressive and anxiety symptoms. Neither depressive nor anxiety symptoms were related to pulling site. Depressive symptoms partially mediated the relationship between TTM severity and functional impairment. Conclusions: Based on an internet sample recruited from the homepage of the Ttichotillomania Learning Center, data from this study suggests that symptoms of depression and anxiety may be pervasive among youth with TTM and likely impact functional impairment. Longitudinal studies using directly assessed samples are needed to replicate and extend these findings. Depression and Anxiety 26:521-527, 2009. (c) 2008 Wiley-Liss, Inc.

Since the secondary palate was an adaptation to breathing on land, we characterized zebrafish tbx22 to study molecular mechanisms regulating early vertebrate craniofacial patterning. Rapid Amplification of cDNA Ends (RACE) analyses revealed two zebrafish tbx22 splice isoforms, tbx22-1 and tbx22-2, encoding proteins of 444 and 400 amino acids, respectively. tbx22-1 resembles canonical Tbx22 orthologs, while tbx22-2 lacks conserved N-terminal sequence. Developmental RT-PCR revealed that tbx22-1 is maternally and zygotically expressed, while tbx22-2 is expressed zygotically. WISH analyses revealed strong tbx22 mRNA expression in ectomesenchyme underlying the stomodeum, a bilaminar epithelial structure demarcating early mouth formation, and in early presumptive jaw joints. Zebrafish tbx22 expression mirrored some aspects of mammalian Tbx22, consistent with roles in early vertebrate face patterning. These studies identify an early transcription factor governing vertebrate facial development, which may underlie common craniofacial birth disorders. Developmental Dynamics 238:1605-1612, 2009.

To search for genes that contribute to diabetic nephropathy, a genome-wide association scan was implemented on the Genetics of Kidneys in Diabetes collection. RESEARCH DESIGN AND METHODS-We genotyped similar to 360,000 single nucleotide polymorphisms (SNPs) in 820 case subjects (284 with proteinuria and 536 with end-stage renal disease) and 885 control subjects with type 1 diabetes. Confirmation of implicated SNPs was sought in 1,304 participants of the Diabetes Control and Complications Trial (DCCT)/Epidemiology of Diabetes Interventions and Complications (EDIC) study, a long-term, prospective investigation of the development of diabetes-associated complications. RESULTS-A total of 13 SNPs located in four genomic loci were associated with diabetic nephropathy with P < 1 x 10(-5). The strongest association was at the FRMD3 (4.1 protein ezrin, radixin, moesin [FERM] domain containing 3) locus (odds ratio [OR] = 1.45, P = 5.0 x 10(-7)). A strong association was also identified at the CARS (cysteinyl-tRNA synthetase) locus (OR 1.36, P = 3.1 x 10(-6)). Associations between both loci and time to onset of diabetic nephropathy were supported in the DCCT/EDIC study (hazard ratio [HR] = 1.33, P = 0.02, and HR = 1.32, P = 0.01, respectively). We demonstrated expression of both FRMD3 and CARS in human kidney. CONCLUSIONS-We identified genetic associations for susceptibility to diabetic nephropathy at two novel candidate loci near the FRMD3 and CARS genes. Their identification implicates previously unsuspected pathways in the pathogenesis of this important late complication of type I diabetes.

TI Cognitive Function Is Disrupted by Both Hypo- and Hyperglycemia in School-Aged Children With Type 1 Diabetes: A Field Study SO DIABETES CARE LA English DT Article ID MENTAL EFFICIENCY; HYPOGLYCEMIA; PERFORMANCE; MELLITUS; GLUCOSE; ADULTS; MILD; IDDM AB OBJECTIVE - We developed a field procedure using personal digital assistant (PDA) technology to test the hypothesis that naturally occurring episodes of hypo- and hyperglycemia are associated with deterioration in cognitive function in children with type 1 diabetes. RESEARCH DESIGN AND METHODS - A total of 61 children aged 6-11. years with type 1 diabetes received a PDA programmed with two brief cognitive tests (mental math and choice reaction time), which they completed just before home glucose readings. The computer recorded Lime to complete each test and number of correct responses. Children completed several trials per day over 4-6 weeks for a total of 70 trials. Performance variables were compared across glucose ranges. Individual impairment scores (IISs) were also computed for each child by calculating the SD between performance during euglycemia and that during glucose extremes. RESULTS - Time to complete both mental math and reaction time was significantly longer during hypoglycemia. During hyperglycemia, time to complete math was significantly longer and reaction time was marginally significant (P = 0.053). There were no differences on task accuracy. Decline in mental math performance was equivalent at glucose levels <3.0 and >22.2 mmol/l. IISs varied greatly across children, with no age or sex differences. CONCLUSIONS - A decrease in mental efficiency occurs With naturally occurring hypo- and hyperglycemic glucose fluctuations in children with type 1 diabetes, and this effect can be detected with a field procedure using PDA technology. With blood glucose levels >22.2 mmol/l, cognitive deterioration equals that associated With significant hypoglycemia.

RESEARCH DESIGN AND METHODS - We assessed 67 youth ages 4-12 years with type 1 diabetes (duration >= 1. year). Parents estimated carbohydrate content of children's meals in diet recalls. Ratios of parent estimates to computer analysis defined carbohydrate counting knowledge; the mean and SD of these ratios defined accuracy and precision, respectively. A1C defined glycemic control. RESULTS - Greater accuracy and precision were associated with lower A1C in bivariate analyses (P < 0.05). In a multivariate analysis (R(2) = 0.25, P = 0.007) adjusting for child age, sex, and type 1 diabetes duration, precision (P = 0.02) and more frequent blood glucose monitoring (P = 0.04), but not accuracy (P = 0.9), were associated with lower A1C. A1C was 0.8% lower (95% CI -0.1 to -1.4) among youth whose parents demonstrated precision.

SO DIABETES CARE LA English DT Article ID INSULIN-RESISTANCE; WEIGHT-LOSS; RISK-FACTORS; OBESE WOMEN; HEART; HYPERTENSION; SENSITIVITY; LIPOSUCTION; IMPROVEMENT; PREVENTION AB OBJECTIVE - Obesity is associated with increased metabolic and cardiovascular risk. The ectopic fat hypothesis suggests that subcutaneous fat may be protective, but this theory has yet to be fully explored. RESEARCH DESIGN AND METHODS - Participants from the Framingham Heart Study (n = 3,001, 48.5% women) were stratified by visceral adipose tissue (VAT) into sex-specific tertiles. Within these tertiles, age-adjusted abdominal subcutaneous adipose tissue (SAT) tertiles were examined in relation to cardiometabolic risk factors. RESULTS - In the lowest VAT fertile, risk factor prevalence was low, although systolic blood pressure in women and rates of high triglycerides, impaired fasting glucose, hypertension, and the metabolic syndrome in men increased with increasing SAT tertile (all P < 0.04). In contrast, in the top VAT tertile, lower triglycerides were observed in men with increasing SAT (64.4% high triglycerides in SAT tertile 1 Vs. 52.7% in SAT tertile 3, P = 0.03). Similar observations were made for women, although results were not statistically significant (50.6% high triglycerides in SAT tertile 1 vs. 41.0% in tertile 3, P = 0.1.0). Results in the highest VAT tertile were notable for a lack of increase in the prevalence of low HDL in men and women and in rates of impaired fasting glucose in men with increasing subcutaneous fat, despite sizable differences in BMI across SAT tertiles (27.1 to 36.3 kg/m(2) [women]; 28.1 to 35.7 kg/m(2) [men]). CONCLUSIONS - Although adiposity increases the absolute risk of metabolic and cardiovascular disease, abdominal subcutaneous fat is not associated with a linear increase in the prevalence of all risk factors among the obese, most notably, high triglycerides.

TI Role of atypical protein kinase C in activation of sterol regulatory element binding protein-1c and nuclear factor kappa B (NF kappa B) in liver of rodents used as a model of diabetes, and relationships to hyperlipidaemia and insulin resistance SO DIABETOLOGIA LA English DT Article DE Atypical protein kinase C; Diabetes; Insulin; IRS-1; IRS-2; Liver; Muscle; Protein kinase B ID GLUCOSE-TRANSPORT; GENE-EXPRESSION; PKC-LAMBDA; MUSCLE; RATS; SENSITIVITY; ADIPOCYTES; METABOLISM; KNOCKOUT; ISOFORMS AB Previous findings in rodents used as a model of diabetes suggest that insulin activation of atypical protein kinase C (aPKC) is impaired in muscle, but, unexpectedly, conserved in liver, despite impaired hepatic protein kinase B (PKB/Akt) activation. Moreover, aPKC at least partly regulates two major transactivators: (1) hepatic sterol receptor binding protein-1c (SREBP-1c), which controls lipid synthesis; and (2) nuclear factor kappa B (NF kappa B), which promotes inflammation and systemic insulin resistance. In Goto-Kakizaki rats used as a model of type 2 diabetes, we examined: (1) whether differences in hepatic aPKC and PKB activation reflect differences in activation of IRS-1- and IRS-2-dependent phosphatidylinositol 3-kinase (PI3K); (2) whether hepatic SREBP-1c and NF kappa B are excessively activated by aPKC; and (3) metabolic consequences of excessive activation of hepatic aPKC, SREBP-1c and NF kappa B. In liver, as well as in muscle, IRS-2/PI3K activation by insulin was intact, whereas IRS-1/PI3K activation by insulin was impaired. Moreover, hepatic IRS-2 is known to control hepatic aPKC during insulin activation. Against this background, selective inhibition of hepatic aPKC by adenoviral-mediated expression of mRNA encoding kinase-inactive aPKC or short hairpin RNA targeting Irs2 mRNA and partially depleting hepatic IRS-2 diminished hepatic SREBP-1c production and NF kappa B activities, concomitantly improving serum lipids and insulin signalling in muscle and liver. Similar improvements in SREBP-1c, NF kappa B and insulin signalling were seen in ob/ob mice following inhibition of hepatic aPKC. In diabetic rodent liver, diminished PKB activation may largely reflect impaired IRS-1/PI3K activation, while conserved aPKC activation reflects retained IRS-2/PI3K activity. Hepatic aPKC may also contribute importantly to excessive SREPB-1c and NF kappa B activities. Excessive hepatic aPKC-dependent activation of SREBP-1c and NF kappa B may contribute importantly to hyperlipidaemia and systemic insulin resistance. C1 [Sajan, M. P.; Standaert, M.

TI An Approach to Post-Radical Trachelectomy Vaginal-Isthmus Cytology SO DIAGNOSTIC CYTOPATHOLOGY LA English DT Article DE cervical cancer; trachelectomy; PAP smears; gyn cytology; vaginal-isthmic anastomosis ID CERVICAL-CANCER; RADICAL TRACHELECTOMY; GLANDULAR CELLS; CARCINOMA; WOMEN; RISK; FERTILITY AB Radical trachelectomy (RT) is the surgical amputation of the uterine cervix with paracervical lymphadenectomy, performed in reproductive age women to treat invasive squamous-cell carcinoma or endocervical adenocarcinoma while preserving the uterine corpus for potential child bearing. Post-RT patient monitoring includes isthmic-vaginal cytology. This study reviews our experience with liquid based preparation of post-RT cytology samples. Fifty-four post-RT vaginal-isthmic cytology specimens were reviewed from nine patients, seven with adenocarcinoma, and two with squamous-cell carcinoma. Five patients had normal (NILM) or normal with reactive changes on all cytology samples. Two patients had isolated squamous abnormalities (atypical squamous-cells of uncertain significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL)); both follow-up biopsies were negative. Two patients had repeatedly abnormal specimens interpreted as a typical glandular cells (AGC), one of whom also had a concurrent ASC-US. Only one sample was tested for high risk human papilloma virus (hrHPV), with negative results. All patients with abnormal cytology went on to have biopsies which were interpreted as benign. The cytology specimens most often interpreted as AGC contained many groups of hyperchromatic crowded glandular cells and/or stromal cells derived from direct sampling of the lower uterine segment. The crowding often limits visualization of all the cells in a group, plus sampled endometrium may harbor mitoses, adding to the atypical appearance. Cytologists should become familiar with the spectrum of changes in the post-RT cytology. Testing for hrHPV should be considered for use in the management of abnormal cytology results. Post RT cytology should be compared with presurgical cytology since one would anticipate similarities in post-RT true positive cases. In particular, a primary diagnosis of adenocarcinoma makes differentiating benign reactive glandular cells from recurrence a critical issue. Diagn. Cytopathol. 200937:437-442.

METHODS: Using data from the linked Surveillance, Epidemiology, and End Results-Medicare database, we analyzed patients with Stage II or III rectal cancer who received adjuvant chemotherapy after curative rectal cancer surgery between 1991 and 2002. Logistic and Cox regressions were performed to assess determinants of adjuvant chemotherapy delays and outcomes in two cohorts: patients with access to medical oncology care because of prior neoadjuvant chemotherapy (Group A) and patients without such access (Group B). Length of postoperative hospital stay served as the main proxy for postsurgical recovery. RESULTS: A total of 442 and 5,617 patients were included in Groups A and B, respectively. The median interval between surgery and adjuvant chemotherapy was 46 days in Group A and 42 days in Group B. Although 17 percent and 11 percent of patients in Groups A and B, respectively, waited three or more months for adjuvant chemotherapy, median overall survival was worse in this subset than in those who waited less than 3 months (54 vs. 76 months, P < 0.01). Postoperative hospital stay independently predicted for adjuvant chemotherapy delay in both groups. Disparities in delays were seen only in Group B, such that patients who were older or black had greater odds of an adjuvant chemotherapy delay (for both, P < 0.05). CONCLUSION: Advanced age and black race contribute to adjuvant chemotherapy delays and inferior outcomes, but postoperative recovery is the more important driver.

In addition to white spots in the fundus, patchy areas of hypopigmentation were noted, which were reminiscent for an early stage of retinitis punctata albescens (RPA). Electroretinographic testing (ERG) showed a non-detectable, dark adapted, isolated rod response and a markedly decreased combined rod and cone response to an achromatic stimulus. After patching one eye overnight, both the isolated rod response and combined rod and cone scotopic white flash response were normal. A Goldmann-Weekers dark adapted final threshold response was also within the normal range. The patient showed a previously reported heterozygous mutation for Gly238Trp, and a novel Arg157Gln mutation. Genetic testing and extended ERG and psychophysical testing may be necessary to diagnose FA from early stages of progressive RPA.

There are currently several FLT3 inhibitors that are undergoing clinical investigation. However, the discovery of drug-resistant leukemic blast cells in FLT3 inhibitor-treated AML patients has prompted the search for novel, structurally diverse FLT3 inhibitors that could be alternatively used to circumvent drug resistance. Here, we provide an overview of FLT3 inhibitors under preclinical and clinical investigation, and we discuss mechanisms whereby AML cells develop resistance to FLT3 inhibitors, and the ways in which combination therapy could potentially be utilized to override drug resistance. We discuss how the cross-talk between major downstream signaling pathways, such as PI3K/PTEN/Akt/mTOR, RAS/Raf/MEK/ERK, and Jak/STAT, can be exploited for therapeutic purposes by targeting key signaling molecules with selective inhibitors, such as mTOR inhibitors, HSP90 inhibitors, or farnesyltransferase inhibitors, and identifying those agents with the ability to positively combine with inhibitors of FLT3, such as PKC412 and sunitinib. With the widespread onset of drug resistance associated with tyrosine kinase inhibitors, due to mechanisms involving development of point mutations or gene amplification of target proteins, the use of a multi-targeted therapeutic approach is of potential clinical benefit.

Despite this, there is a paucity of information regarding the stability and reliability of measurements tools used for dysphagia research. As both head and neck (H&N) cancer and its treatment(s) have been shown to significantly affect deglutitive tongue function, it is important that we have a reliable method to measure swallowing tongue function in this population. In this study we evaluate the reliability and stability of oro-lingual swallowing pressures captured from H&N cancer patients and from healthy, age- and gender-matched controls using the Kay Swallowing Workstation (KSW) fixed, three-transducer tongue pressure array. Significant differences between the two samples (H&N cancer and controls), with respect to mean peak oro-lingual pressures were recorded during swallowing. Furthermore, reliability of these measures was lower in H&N cancer patients. These differences highlight the importance of obtaining information about the reliability of dysphagia assessment tools with the specific population with whom they will be used.

Robbins, JoAnne TI Comparison of Trained Clinician Ratings with Expert Ratings of Aspiration on Videofluoroscopic Images from a Randomized Clinical Trial SO DYSPHAGIA LA English DT Article DE Deglutition; Aspiration; Accuracy; Clinical trial; Penetration/Aspiration Scale; Deglutition disorders ID PENETRATION; INTERVENTIONS; RELIABILITY; INTERJUDGE; AGREEMENT; SCALE AB Accurate detection and classification of aspiration is a critical component of videofluoroscopic swallowing evaluation, the most commonly utilized instrumental method for dysphagia diagnosis and treatment. Currently published literature indicates that interjudge reliability for the identification of aspiration ranges from poor to fairly good depending on the amount of training provided to clinicians. The majority of extant studies compared judgments among clinicians. No studies included judgments made during the use of a postural compensatory strategy. The purpose of this study was to examine the accuracy of judgments made by speech-language pathologists (SLPs) practicing in hospitals compared with unblinded expert judges when identifying aspiration and using the 8-point Penetration/Aspiration Scale. Clinicians received extensive training for the detection of aspiration and minimal training on use of the Penetration/Aspiration Scale. Videofluoroscopic data were collected from 669 patients as part of a large, randomized clinical trial and include judgments of 10,200 swallows made by 76 clinicians from 44 hospitals in 11 states. Judgments were made on swallows during use of dysphagia compensatory strategies: chin-down posture with thin liquids and head-neutral posture with thickened liquids (nectar-thick and honey-thick consistencies). The subject population included patients with Parkinson's disease and/or dementia. Kappa statistics indicate high accuracy for all interventions by SLPs for identification of aspiration (all kappa > 0.86) and variable accuracy (range = 69-76%) using the Penetration/Aspiration Scale when compared to expert judges. It is concluded that while the accuracy of identifying the presence of aspiration by SLPs is excellent, more extensive training and/or image enhancement is recommended for precise use of the Penetration/Aspiration Scale.
