    The authors conducted a preliminary assessment of hepatitis B vaccination rates among men 18- to 37-years-old who have sex with men in a college town to determine what proportion were willing to be vaccinated. Participants, who were sampled in gay bars, gay advocacy groups, a swim team, and a dance club, completed a 25-item questionnaire. Sixty-seven percent were aware of the hepatitis B vaccine, yet only 22% had received the full series of three injections; only 37% had been tested for the virus. On a scale of 1 to 10 for willingness to be vaccinated (10 being most willing), 58% indicated a 10 (M = 8.5). Thirty percent indicated they received safer sex information from university health services, and 14% reported they had received hepatitis B vaccination information there. Hepatitis B vaccination of men who have sex with men in college towns should be a high priority for university health services. PMID:9919848

    Hepatic artery infusion chemotherapy is used in the treatment of certain selected hepatic tumors, especially metastatic adenocarcinoma of the colon. Chemical cholecystitis has been recognized recently as a complication of hepatic artery infusion chemotherapy. The authors performed hepatobiliary scans on ten patients receiving hepatic artery infusion chemotherapy. All ten patients had abnormal hepatobiliary scintigraphy. They present case reports of three patients with abnormal hepatobiliary scans who have required cholecystectomy for symptoms of chemical cholecystitis to illustrate the clinical, scintigraphic, and pathologic findings in these patients.

    Acute hepatitis C infection is recognized in HIV-infected men who have sex with men (MSM), but the risk in HIV-negative MSM remains unclear. We evaluated a population of MSM with acute hepatitis C. From January 2010 to May 2014, all cases of HCV antibody positive HIV-negative MSM were identified. European AIDS Network criteria were applied to determine acute infection, and 44 individuals fulfilled the criteria for acute hepatitis C. Ten were RNA negative at baseline and classed as prior spontaneous clearance. 15 (34.1%) had a previously negative HCV antibody within 1 year. 11 (25.0%) had significant elevation in ALT levels, and 18 (40.9%) were clinically diagnosed from risk exposure and history. Median age was 37 years (range 24-75). 41 (93.2%) individuals reported unprotected anal sex, 36 with (87.8%) both insertive and receptive intercourse, 4 (9.8%) with receptive intercourse, 1 (2.4%) with insertive intercourse, and no data were recorded for 3 (7.3%) patients. Individuals had an average of 7.3 reported (median 2, range 1-100) partners. 12 (27.3%) engaged in group sex, 11 (25.0%) practised fisting, 11 (25.0%) admitted using drugs during sexual activity, 16 (36.4%) reported nasal, and 9 (20.5%) reported injection drug use. 14 (31.8)% had unprotected sex whilst under the influence of recreational drugs. 29 individuals were aware of a partner's status. 2 (4.5%) individuals had sexual contact with a known HCV monoinfected partner, 13 (29.5%) with a HIV monoinfected partner and 6 (13.6%) with a HCV/HIV coinfected partner. 9 (20.5%) reported a partner/partners with no known infection. No data were available in 14 (31.8%) individuals. 13 (29.5%) individuals had a coexisting STI at the time of acute HCV diagnosis. 8 (18.2%) received HIV postexposure prophylaxis (PEP) within the 6 months prior to the HCV diagnosis (2 were participants in a HIV pre-exposure prophylaxis trial). 15 (34.1%) individuals achieved spontaneous clearance of HCV, and 11 patients received HCV

    Cytomegalovirus is a double stranded DNA virus that can be present in nearly all organs and body fluids. The primary infection is usually asymptomatic in the immunocompetent host and it is common among adolescents and young adults. The symptomatic form appears, in the majority of cases, as a mononucleosis syndrome with full recovery without specific treatment. We report a case of a 25 years old woman who presented with hepatitis due to CMV infection and history of omalizumab administration one month earlier. This recombinant monoclonal antibody is used to control refractory asthma and chronic spontaneous urticarial as it inhibits human IgE. Despite that, the long course of the disease lead us to initiate treatment with valganciclovir. The improvement after that was rapid and complete. PMID:27583207

    Two patients receiving hepatic artery infusion chemotherapy (HAIC) required cholecystectomy for both acute and chronic cholecystitis with cholelithiasis suggesting chemical cholecystitis. To evaluate the incidence of gall bladder dysfunction in patients receiving HAIC, the authors performed hepatobiliary scintigraphy using Tc-99m DISIDA or PIPIDA on eight patients receiving HAIC through an indwelling hepatic artery catheter and Infusaid (trademark) pump. In 7 of 8 patients, there was non-visualization of the gall bladder throughout the hepatobiliary study. In the eighth patient, the gall bladder visualized at 2 hr. One patient with non-visualization of the gall bladder at 4 hr developed acute symptoms requiring cholecystectomy which showed acute and chronic cholecystitis with cholethiasis. There was prominent sclerosis which was thought to be due to chemical cholecystitis as well as cholelithiasis. In all 10 patients, no evidence of cholecystitis had been observed during the surgical placement of the hepatic artery catheter and Infusaid pump. The hepatobiliary scintigraphic finding of gall bladder dysfunction in all eight patients studied is most likely due to chemical cholecystitis from HAIC. This series suggests that chemical cholecystitis is common during HAIC and can be identified by hepatobiliary scintigraphy. The authors consider elective cholecystectomy during the operative placement of the hepatic artery catheter and Infusaid pump.

    Hepatitis B virus (HBV) reactivation is well documented in previously resolved or inactive HBV carriers who receive cancer chemotherapy. The consequences of HBV reactivation range from self-limited conditions to fulminant hepatic failure and death. HBV reactivation also leads to premature termination of chemotherapy or delay in treatment schedules. This review summarizes current knowledge of management of HBV reactivation in patients receiving cancer chemotherapy. HBV surface antigen (HBsAg) testing should be performed in patients who require cancer chemotherapy. Four meta-analyses support lamivudine prophylaxis for HBV reactivation during chemotherapy in HBsAg-positive patients. Randomized controlled trials to compare different HBV antiviral agents are needed to define optimal regimens for the prevention and treatment of HBV reactivation in patients receiving cancer chemotherapy.

    Background Cambodian Americans have high rates of chronic hepatitis B virus (HBV) infection and liver cancer. There is very limited information about the utility of community health worker (CHW) approaches to cancer education for Asian American men. We have previously reported our positive findings from a trial of CHW education about HBV for Cambodian Americans who had never been tested for HBV. This report describes similarities and differences between the outcomes of our CHW HBV educational intervention among Cambodian American men and women. Methods The study group for this analysis included 87 individuals (39 men and 48 women) who were randomized to the experimental (HBV education) arm of our trial, participated in the CHW educational intervention, and provided follow-up data six months post-intervention. We examined HBV testing rates at follow-up, changes in HBV-related knowledge between baseline and follow-up, and barriers to HBV testing (that were reported to CHWs) by gender. Results At follow-up, 15% of men and 31% of women reported they had received a HBV test (p=0.09). HBV-related knowledge levels increased significantly among both men and women. With respect to HBV testing barriers, women were more likely than men to cite knowledge deficits, and men were more likely than women to cite logistic issues. Discussion Our study findings indicate that CHW interventions can positively impact knowledge among Cambodian American men, as well as women. They also suggest CHW interventions may be less effective in promoting the use of preventive procedures by Cambodian American men than women. Future CHW research initiatives should consider contextual factors that may differ by gender and, therefore, potentially influence the relative effectiveness of CHW interventions for men versus women.

    An acute hepatitis C infection was diagnosed in three HIV-positive gay men, aged 43, 48 and 30 years, respectively. In all three, unprotected sexual intercourse and fisting was a universal risk factor for the infection. They all denied having used drugs intravenously, which is the most common risk factor. The third man had a documented proctitis (lymphogranuloma venereum) at the time when the HCV transmission must have taken place. No serious complications occurred during the acute HCV infection. Because the infection did not resolve spontaneously after a few months, all three men were treated with pegylated interferon and ribavirin. Recently, the number of cases of acute HCV infection has been seen to increase in The Netherlands. This may be due primarily to an increase in unprotected sexual intercourse and fisting. This hypothesis is supported by a documented increased prevalence of sexually transmissible diseases among gay men in The Netherlands. As acute infections may turn into chronic infections, treatment of an acute infection should be considered in order to prevent the chronic disease. PMID:15587046

    While hepatitis C virus (HCV) is known to be transmitted parenterally, the role of sexual transmission remains unclear. In order to examine the association of sexual risk factors with HCV seroprevalence at a time when unprotected sexual practices were still quite common, 435 homosexual men recruited from a municipal sexually transmitted disease clinic with behavioural data and serologic specimens from 1983-1984 were evaluated. Overall, 25% of men reporting injecting drug use (IDU) and 5% of men with no IDU were anti-HCV positive; the rate in the non-IDU was significantly higher than age-matched rates in blood donors (summary odds ratio 3.5, 95% confidence interval 2.8-4.2). In addition to IDU, amphetamine and phencyclidine use were also associated with anti-HCV positivity on univariate analysis. Sexual risk factors for anti-HCV positivity included anal receptive intercourse, 'fisting', having an IDU sexual partner, a self-reported history of genital herpes and HIV seropositivity. On multivariate analysis, only IDU was significantly associated with anti-HCV positivity. Thus, sexual practices appear to play a minor role in transmission of HCV. PMID:7884219

    We investigate the impact of dutasteride on prostate specific antigen (PSA) and prostate volume in men receiving testosterone (T) therapy. Twenty-three men on stable dose T therapy were randomised to receive either dutasteride or placebo for 12 months. Serum levels of PSA, T and dihydrotestosterone (DHT) and responses to the International Index of Erectile Function (IIEF) and Male Sexual Health Questionnaire (MSHQ) questionnaires were determined at baseline and at 3, 6, 9 and 12 months. Prostate volume (PV) was measured using transrectal ultrasound (TRUS) at baseline and again after 12 months. A total of 22 men (mean age 57.3) completed the study, with 11 men receiving placebo and 11 receiving dutasteride. Men receiving dutasteride had a significant decrease in PSA (-0.46 ± 0.81 ng ml(-1) ; P = 0.04) and in PV (-6.65 ± 11.0%; P = 0.03) from baseline over 12 months. DHT decreased significantly for men on dutasteride compared with men receiving placebo (P = 0.02). When compared with men who received placebo, men who received dutasteride demonstrated nonsignificant trends towards decreased PSA (-0.46 versus 0.21 ng ml(-1) ; P = 0.11), PV (-6.65% versus 3.4%; P = 0.08) and MSHQ scores (-10.2 versus 5.6; P = 0.06). Dutasteride reduces PSA and PV for men on T therapy, but perhaps less so than in men without T therapy. PMID:24499051

    HIV-infected patients are at increased risk for acquiring hepatitis A virus (HAV) infection. We evaluated the seroconversion rate (anti-HAV antibodies ≥ 20 mIU/ml) and the geometric mean antibody titres (GMTs) in a group of 351 HIV infected men, who had received two doses of a hepatitis A vaccine. We analysed blood samples collected at one, six, 12 and 18 months following the administration of the second dose of the vaccine. The seroconversion rate one month after the second dose of the vaccine was 74.4% (260/351). At month 18 after the end of vaccination, 56.1% of the subjects remained seropositive. GMTs were 315, 203, 153 and 126 mIU/ml at months 1, 6, 12, and 18, respectively. Logistic regression revealed that the CD4 count is the only factor affecting response to vaccination (P = 0.019). A higher response rate and higher GMTs were observed in patients with CD4 counts ≥ 500 cells/mm(3) (76.6%) than in patients with CD4 counts 200-499 cells/mm(3). In conclusion, even in patients with near-normal CD4 counts, the response to the hepatitis A vaccine is impaired. PMID:22843998

    In mid-2004, three Parisian hospital wards informed the Institut de veille sanitaire of recent acute hepatitis C in HIV-infected (HIV+) men who had sex with men (MSM). These cases for whom none of the usual bloodborne routes for hepatitis C (HCV) transmission was found, reported having had unprotected sex. In October 2004, we conducted a retrospective investigation in Parisian hospital wards to explore HCV modes of transmission in recent acute hepatitis C in HIV+ MSM. Patient demographics, clinical and biological status of HIV infection, reasons for HCV testing, sexual behaviour and risk factors for HCV transmission within the 6 months before hepatitis onset were collected from medical records. An anonymous self-administered questionnaire on sexual behaviour within the six months before hepatitis onset was also offered to all cases. We identified 29 cases of acute hepatitis C in HIV+ MSM with onset from April 2001 to October 2004. HIV infection was asymptomatic for 76%. Median age at hepatitis C onset was 40 (28-54) years. In all records, were noted unprotected anal sex, fisting in 21% and a concomitant sexually transmitted infection (STI) in 41%. Median time between HIV diagnosis and HCV infection was 6.5 years (0-22). From the 11 self-administered questionnaires completed, 10 reported an STI, 8 'hard' sexual practices, 6 bleeding during sex and 5 fisting. HCV transmission probably occurred through bleeding during unprotected traumatic anal sex among HIV+ MSM and may be facilitated by STI mucosal lesions. This report stresses the continuous need to strongly advocate safer sex to MSM. PMID:16077209

    Introduction There has been a significant rise in the number of HIV positive men who have sex with men (MSM) co-infected with hepatitis C (HCV). Most infections are thought to occur through high risk sexual practices, exacerbated by drug use. Previous data has suggested no need for routine screening in HIV negative MSM. We looked at HCV antibody testing and HCV risk assessment in all MSM clinic attenders as part of a Public Health England initiative. Materials and Methods Routine HCV antibody testing was offered to all MSM attending a large inner city sexual health clinic from April to June 2014. Patients were asked to fill in a questionnaire assessing HCV risk. Demographic data, HIV status and STI results were collected and compared. Results We collected 471 HCV risk assessment questionnaires during the eight-week period. The median age was 34 (range 18–71) and 403 (85.6%) were White British. Ten (2.1%) patients were known to be HCV positive, of which 3 were on treatment and 5 (1.1%) had cleared HCV. One hundred and forty-nine (31.6%) patients were HIV negative, 254 (53.9%) were HIV positive and 68 (14.5%) had unknown HIV status at time of clinic visit. In the last three months 151 (32.1%) reported unprotected receptive anal intercourse, 58 (12.3%) reported group sex, 11 (2.3%) reported receptive fisting and 32 (6.8%) reported more than 10 partners. Eighty-seven (18.5%) patients had shared notes/straws to snort drugs and 29 (6.2%) reported injecting drugs or slamming. One hundred and forty-two (30.0%) patients reported recreational drug use in the last 12 months, with cocaine, methadrone and ketamine most popular. One hundred and fifteen (24.4%) patients reported sex under the influence of recreational drugs. There were no statistical differences between HIV positive and HIV negative patients in their risk, sexual behaviour and drug use. STI screens were performed on 269 patients with nine (3.3%) new HIV diagnoses, four (1.5%) early syphilis, and 28 (10

    OBJECTIVES: This study investigated hepatitis B immunization coverage and the extent of hepatitis B virus (HBV) infection among young men who have sex with men (MSM), a group for whom hepatitis B vaccine has been recommended since 1982. METHODS: We analyzed data from 3432 MSM, aged 15 to 22 years, randomly sampled at 194 gay-identified venues in 7 US metropolitan areas from 1994 through 1998. Participants were interviewed, counseled, and tested for serologic markers of HBV infection. RESULTS: Immunization coverage was 9% and the prevalence of markers of HBV infection was 11%. HBV infection ranged from 2% among 15-year-olds to 17% among 22-year-olds. Among participants susceptible to HBV infection, 96% used a regular source of health care or accessed the health care system for HIV or sexually transmitted disease testing. CONCLUSIONS: Despite the availability of an effective vaccine for nearly 2 decades, our findings suggest that few adolescent and young adult MSM in the United States are vaccinated against hepatitis B. Health care providers should intensify their efforts to identify and vaccinate young MSM who are susceptible to HBV. PMID:11392942

    Several outbreaks of hepatitis A in men who have sex with men (MSM) were reported in the 1980s and 1990s in Australia and other countries. An effective hepatitis A virus (HAV) vaccine has been available in Australia since 1994 and is recommended for high-risk groups including MSM. No outbreaks of hepatitis A in Australian MSM have been reported since 1996. In this study, we aimed to estimate HAV transmissibility in MSM populations in order to inform targets for vaccine coverage in such populations. We used mathematical models of HAV transmission in a MSM population to estimate the basic reproduction number (R 0) and the probability of an HAV epidemic occurring as a function of the immune proportion. We estimated a plausible range for R 0 of 1·71-3·67 for HAV in MSM and that sustained epidemics cannot occur once the proportion immune to HAV is greater than ~70%. To our knowledge this is the first estimate of R 0 and the critical population immunity threshold for HAV transmission in MSM. As HAV is no longer endemic in Australia or in most other developed countries, vaccination is the only means of maintaining population immunity >70%. Our findings provide impetus to promote HAV vaccination in high-risk groups such as MSM. PMID:26566273

    Introduction In this study, we aimed to evaluate the safety of using different sources of sperm when male partners were infected with hepatitis B virus (HBV). Material and methods A total of 338 couples receiving their first intracytoplasmic sperm injection (ICSI) cycle at the Department of Reproduction, Ren Ji Hospital, between 2007 and 2012 were enrolled if the female partner tested negative for HBV DNA, HBsAg, HBeAg, HBeAb and HBcAb. Couples were divided into HBV active infection (group B), convalescent infection (group C) and controls (group A). Subgroups were divided by source of sperm: ejaculated sperm and testicular sperm aspiration/percutaneous epididymal sperm aspiration (TESA/PESA) sperm. Results When using ejaculated sperm for ICSI, two pronuclear (2PN) fertilization rate, implantation rate, clinical pregnant rate, early miscarriage rate and live birth rate showed no significant difference between the three groups. However, in the three TESA/PESA groups, the early miscarriage rate was highest in men with active HBV infection (B2) (23.1%, p = 0.035). The 2PN fertilization rate and CPR were also lower in the active infection group (76.7%, 26.3%) than the convalescent infection (82.9%, 36.2%) and control group (78.2%, 50%), but the difference was not statistically significant. No malformed infant was found in any of these groups. Conclusions When men have an active HBV infection, using TESA/PESA sperm may cause lower fertilization, a high miscarriage rate and a lower live birth rate, which indicates that HBV active infection may cause adverse effects on ICSI reproductive performance when using testicular or epididymal aspirated sperm.

    Background. The epidemic of sexually transmitted hepatitis C virus (HCV) infection among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) has been documented for over a decade. Despite this, there is no consensus as to the risk factors for sexual acquisition of HCV in these men. Methods. We obtained paired semen and blood samples at 2-week intervals from HIV-infected MSM with recent and chronic HCV infection and quantified HCV in semen. Results. Hepatitis C virus was quantified in 59 semen specimens from 33 men. Hepatitis C virus was shed in 16 (27%) of semen specimens from 11 (33%) of the men. Median HCV viral load (VL) in semen was 1.49 log10 IU/mL. Hepatitis C virus VL in blood was significantly higher at the time of HCV shedding in semen than when HCV shedding in semen was not detected (P = .002). Furthermore, there was a significant correlation between the HCV VL in blood and semen overall (rs = 0.41; P = .001), and in the subgroup with recent HCV infection (rs = 0.37; P = .02), but not in the subgroup with chronic HCV infection (rs = 0.34; P = .1). Conclusions. One third of HIV-infected MSM coinfected with HCV shed HCV into their semen. Based on the HCV VL in semen in this study, an average ejaculate would deliver up to 6630 IU of virus into the rectum of the receptive partner. Therefore, our data strongly support that condoms should be used during anal intercourse among MSM to prevent transmission of HCV. PMID:27186582

    In this study of factors related to Hepatitis C virus (HCV) infection in 104 homeless HCV-infected men and 94 uninfected homeless men, findings reveal that homeless men with HCV infection are older and more likely to be cocaine injectors than those not infected. Moreover, the sharing of needles, use of injected cocaine during the past 6 months, previous incarceration, veteran status, fair or poor health, and having multiple tattoos are also associated with HCV infection. Reports of having completed the HBV vaccination series, weekly marijuana use, and snorting cocaine or methamphetamine are negatively associated with HCV infection. Among men not reporting lifetime injection drug use, factors such as sharing toothbrushes, having multiple tattoos, being in fair or poor health, and past incarceration are associated with HCV infection. These findings may need to be considered when making screening decisions and counseling homeless male patients about HCV. PMID:16672633

    Work by K. Tolley indicates that girls in mid to late 19th century U.S. high schools were more likely to study mathematics and natural philosophy (i.e., physics and astronomy) than were boys (who pursued the classics).* She also found that after the turn of the century women were more likely than men to receive bachelor's degrees in math and biological sciences at Stanford, but her sampling of every fifth year yielded too few data to be conclusive about physics. Reexamination of graduation lists at Stanford, yielding data for each year from 1900 to 1929, shows that, while absolute numbers were small, women were as likely as men to receive bachelor's degrees in physics during the first decade of the century, in the second decade they were notably more likely, and in the third their likelihood decreased substantially, while that of men rose to exceed that of women. (Women were much more likely to receive bachelor's degrees in math, exceeding the likelihood for men by an order of magnitude during the second and third decades.) *K.

    Background Prospective characterization of hepatitis C virus (HCV) transmission in both human immunodeficiency virus (HIV)–infected and –uninfected men who have sex with men (MSM) over the entire HIV epidemic has not been comprehensively conducted. Methods To determine the trends in and risk factors associated with incident HCV in MSM since 1984, 5310 HCV antibody (anti-HCV)–negative MSM in the Multicenter AIDS Cohort Study were prospectively followed during 1984–2011 for anti-HCV seroconversion. Results During 55 343 person-years (PYs) of follow-up, there were 115 incident HCV infections (incidence rate, 2.08/1000 PYs) scattered throughout the study period. In a multivariable analysis with time-varying covariates, older age (incidence rate ratio [IRR], 1.40/10 years, P < .001), enrollment in the later (2001–2003) recruitment period (IRR, 3.80, P = .001), HIV infection (IRR, 5.98, P < .001), drinking >13 alcoholic drinks per week (IRR, 1.68, P < .001), hepatitis B surface antigen positivity (IRR, 1.68, P < .001), syphilis (IRR, 2.95, P < .001), and unprotected receptive anal intercourse with >1 male partner (IRR, 3.37, P < .001) were independently associated with incident HCV. Among HIV-infected subjects, every 100 cell/mm3 increase in CD4 count was associated with a 7% (P = .002) decrease in the HCV incidence rate up to a CD4 count of 500 cells/mm3, whereas there was no association with highly active antiretroviral therapy. Conclusions The spread of HCV among both HIV-infected and -uninfected MSM in the United States has been ongoing since the beginning of the HIV epidemic. In HIV-infected men with <500 CD4+ T cells, the HCV incidence rate was inversely proportional to CD4 T-cell count. PMID:23532480

    This study was designed to develop reliable and valid quantitative measures of the beliefs and attitudes toward hepatitis B virus (HBV) vaccination among gay men, using a community-based participatory research approach. A convenience sample of 358 gay men was recruited in two gay bars. Exploratory factor analysis performed on the first split-half sample was used to assess the factor structure from five scales measuring beliefs about HBV vaccination. The scales were based on constructs from the health belief model and the social cognitive theory. Confirmatory factor analysis was performed on the remaining half-sample using structural equation modeling. Multivariable analysis further validated the scales. These findings propose standardized measures that may be useful in assessing the beliefs and attitudes of gay men toward HBV vaccination to guide intervention design and evaluation. PMID:18928048

    Patients diagnosed with lymphogranuloma venereum have high rates of co-infection with HIV, syphilis and hepatitis C. The aim of this enhanced surveillance was to screen all men who have sex with men (MSM) newly diagnosed with HIV, syphilis or hepatitis C for co-infection with asymptomatic lymphogranuloma venereum as part of the recommended sexual health screen. Of the 145 patients screened, 21 patients were diagnosed with rectal Chlamydia trachomatis, one with both rectal and urethral chlamydia and six with urethral chlamydia. One rectal chlamydia-positive sample, when tested, was equivocal for lymphogranuloma venereum. Our data suggested that there was not a pool of asymptomatic lymphogranuloma venereum infection in MSM recently diagnosed with HIV, hepatitis C and syphilis. However, there have been recent reports of an increased incidence of asymptomatic lymphogranuloma venereum, raising the question whether lymphogranuloma venereum should be screened for in high risk asymptomatic MSM. The prevalence of asymptomatic rectal chlamydia infections was 19%. PMID:26158451

    Dearth of information regarding the trend and correlates of HIV, syphilis and Hepatitis C (HCV) in a country-wide sample of understudied though high-risk Chinese men who have sex with men (MSM) called for a comprehensive serial cross-sectional study. Using a multistage mixed-method strategy, 171,311 MSM from 107 selected cities/counties in 30 provinces of mainland China, were interviewed and tested. Descriptive, bivariate, multivariate and Cochran-Armitage trend analyses were conducted using SAS 9.2. During 2009-13, recent (71.5% to 78.6%, p < 0.001) and consistent (40.4% to 48.8%, p < 0.001) condom use as well as condom use during commercial anal sex (46.5% to 55.0%, p < 0.001) were increasing. In contrast, commercial anal sex with male (11.9% to 7.1%, p < 0.001) and drug use (1.9% to 0.8%, p < 0.001) were decreasing over time. HIV prevalence increased gradually (5.5% to 7.3%, p < 0.001), while syphilis (9.0% to 6.3%, p < 0.001) and HCV prevalence (1.5% to 0.7%, p < 0.001) decreased over time. A positive correlation was observed between HIV and syphilis prevalence (r = 0.38). HIV infection was associated with HIV-related knowledge, services and injecting drug use. An increasing trend of HIV prevalence was observed during 2009–13 among MSM in China. While gradual reduction of risk behaviors along with syphilis and HCV prevalence supported expansion of testing and prevention services, increasing HIV burden called for deeper thematic investigations.

    OBJECTIVE The pathophysiological mechanisms to explain the association between risk of type 2 diabetes and elevated concentrations of γ-glutamyltransferase (GGT) and alanineaminotransferase (ALT) remain poorly characterized. We explored the association of liver enzymes with peripheral and hepatic insulin resistance, insulin secretion, insulin clearance, and glucagon concentration. RESEARCH DESIGN AND METHODS We studied 1,309 nondiabetic individuals from the Relationship between Insulin Sensitivity and Cardiovascular disease (RISC) study; all had a euglycemic-hyperinsulinemic clamp and an oral glucose tolerance test (OGTT) with assessment of insulin secretion and hepatic insulin extraction. The hepatic insulin resistance index was calculated in 393 individuals. RESULTS In both men and women, plasma concentrations of GGT and ALT were inversely related with insulin sensitivity (M/I) (all P < 0.01). Likewise, the hepatic insulin resistance index was positively correlated with both GGT (r = 0.37, P < 0.0001, men; r = 0.36, P < 0.0001, women) and ALT (r = 0.25, P = 0.0005, men; r = 0.18, P = 0.01, women). These associations persisted in multivariable models. Increased GGT and ALT were significantly associated with higher insulin secretion rates and with both reduced endogenous clearance of insulin and hepatic insulin extraction during the OGTT (P = 0.0005 in men; P = 0.003 in women). Plasma fasting glucagon levels increased over ALT quartiles (men, quartile 4 vs. quartile 1 11.2 ± 5.1 vs. 9.3 ± 3.8 pmol/L, respectively, P = 0.0002; women, 9.0 ± 4.3 vs. 7.6 ± 3.1, P = 0.001). CONCLUSIONS In healthy individuals, increased GGT and ALT were biomarkers of both systemic and hepatic insulin resistance with concomitant increased insulin secretion and decreased hepatic insulin clearance. The novel finding of a positive correlation between ALT and fasting glucagon level concentrations warrants confirmation in type 2 diabetes. PMID:21521874

    Objective Prostate cancer patients who receive androgen deprivation therapy (ADT) often experience many physical and psychological side effects. ADT may be associated with increased risk for depression, but the relationship between ADT and depression is not fully understood. This study used a longitudinal design to assess depressive symptomatology in patients receiving ADT compared to two groups of matched controls. Methods Participants were men initiating ADT treatment (ADT+ group; n = 61) and their matched controls: prostate cancer patients treated with radical prostatectomy (ADT− group; n = 61) and no-cancer controls (CA− group; n = 61). Depressive symptomatology was assessed using the Center for Epidemiological Studies Depression Scale at ADT initiation and again six months later. Differences in depressive symptomatology and rates of clinically-significant depressive symptomatology were analyzed between groups at each time point and within groups over time. Results: Between baseline and follow-up, ADT+ participants demonstrated increased depressive symptomatology and increased rates of clinically-significant depressive symptomatology (ps < .05). ADT+ participants also reported greater depressive symptomatology than both control groups at follow-up (ps < .001). Rates of clinically-significant depressive symptomatology were higher in the ADT+ group than the ADT− and CA− groups at both time points (baseline: 28%, 5%, 12%; follow-up: 39%, 9%, 11%). Conclusions Findings support the hypothesis that ADT administration yields increases in depression and suggest that the mechanism behind ADT’s association with depression should be explored and that prostate cancer patients treated with ADT should receive particular focus in depression screening and intervention.

    Background The purpose of this study was to evaluate the prevalence, patterns and predictors (individual, social, cultural, and environmental) of illicit drug use and binge drinking in a cohort of Latino migrant men (LMM) in a new receiving community. Methods A cohort of LMM in New Orleans (n = 125) was assembled in 2007 using respondent driven sampling and interviewed quarterly for 18 months regarding past month substance use and other potential covariates. Baseline frequencies were weighted using RDSAT and longitudinal analyses included generalized estimating equations (GEE) and the Cochran–Armitage test for trends. Results At baseline, substance use behaviors were: drug use 15.0% (range 7.3–25.0%) and binge drinking 58.3% (range 43.6–74.6%). All three of these behaviors decreased over follow-up (P < 0.01). Baseline alcohol dependence and drug problem were 11.8% (range 5.6–24.3%) and 0.08% (range 0.00–2.7%) and both remained the same over time. Baseline rate of chlamydia was 9% (range 0.00–22.4%); all men tested negative for gonorrhea, HIV, and syphilis. For both binge drinking and drug use, having sex with a female sex worker was associated with increased risk, whereas belonging to a club or organization was associated with less risk. Additional factors associated with increased drug use were: having a friend in New Orleans upon arrival, symptoms of depression, and working in construction. An additional factor associated with less binge drinking was having family in New Orleans upon arrival. Conclusion Among LMM, substance use is influenced by social and environmental factors. Interventions increase community connectedness may help decrease usage. PMID:24099968

    To ascertain why active and passive oral-anal and genital anal intercourse correlate strongly with hepatitis B virus (HBV) infection in homosexual men, we studied 22 men with HBV infection for the presence of hepatitis B surface antigen (HBsAg) in gingival and anorectal mucosa, feces, and semen. Thirteen of 22 (59%) patients had asymptomatic rectal mucosal lesions consisting of punctate bleeding points. Seventy-seven percent of swabbed specimens from lesions, 62% from feces, 59% from rectal mucosa, and 50% from anal canal mucosa contained HBsAg. Sera diluted serially and tested for HBsAg by radioimmunoassay showed that men with serum titers of 105 or greater were more likely to have HBsAg in specimens from lesions (p = 0.034), feces (p = 0.032), and normal mucosa (p = 0.001) than men with titers under 10 5. Asymptomatic rectal bleeding is frequent in homosexual men with persistent HBV infection. Rectal mucosa, feces, and anal canal mucosa become contaminated with HBsAg, creating a setting for de facto parenteral transmission when there is contact with oral or urethral mucosa. PMID:7059064

    Background Although hepatitis A virus (HAV) and hepatitis B virus (HBV) infections are vaccine-preventable diseases, few homeless parolees coming out of prisons and jails have received the hepatitis A and B vaccination series. Objectives The study focused on completion of the HAV and HBV vaccine series among homeless men on parole. The efficacy of three levels of peer coaching and nurse-delivered interventions was compared at 12-month follow up: (a) intensive peer coaching and nurse case management (PC-NCM); (b) intensive peer coaching (PC) intervention condition, with minimal nurse involvement; and a (c) usual care (UC) intervention condition, which included minimal PC and nurse involvement. Further, we assessed predictors of vaccine completion among this targeted sample. Methods A randomized control trial was conducted with 600 recently paroled men to assess the impact of the three intervention conditions (PC-NCM vs. PC vs. UC) on reducing drug use and recidivism; of these, 345 seronegative, vaccine-eligible subjects were included in this analysis of completion of the Twinrix HAV/HAB vaccine. Logistic regression was added to assess predictors of completion of the HAV/HBV vaccine series and chi-squared analysis to compare completion rates across the three levels of intervention. Results Vaccine completion rate for the intervention conditions were 75.4% (PC-NCM), 71.8% (PC), and 71.9% (UC) (p =. 78). Predictors of vaccine noncompletion included being Asian and Pacific Islander, experiencing high levels of hostility, positive social support, reporting a history of injection drug use, being released early from California prisons, and being admitted for psychiatric illness. Predictors of vaccine series completion included reporting six or more friends, recent cocaine use, and staying in drug treatment for at least 90 days. Discussion Findings allow greater understanding of factors affecting vaccination completion in order to design more effective programs among the

    This paper explores motivational factors and barriers to sexual behaviour change among men receiving antiretroviral treatment (ART). Twenty in-depth interviews were undertaken with male patients enrolled at the African Medical and Research Foundation clinic in Africa's largest urban informal settlement, Kibera in Nairobi, Kenya. All participants experienced prolonged and severe illness prior to the initiation of ART. Fear of symptom relapse was the main trigger for sexual behaviour change. Partner reduction was reported as a first option for behaviour change since this decision could be made by the individual. Condom use was perceived as more difficult as it had to be negotiated with female partners. Cultural norms regarding expectations for reproduction and marriage were not supportive of sexual risk-reduction strategies. Thus, local sociocultural contexts of HIV-infected people must be incorporated into the contextual adaptation and design of ART programmes and services as they have an over-riding influence on sexual behaviour and programme effectiveness. Also, HIV-prevention interventions need to address both personal, micro- and macro-level factors of behaviour to encourage individuals to take on sexual risk-reduction strategies. In order to achieve the anticipated preventive effect of ART, these issues are important for the donor community and policy-makers, who are the major providers of ART programme support within weak health systems in sub-Saharan Africa.

    Background Lamivudine monotherapy is effective in suppressing hepatitis B virus (HBV) replication to undetectable levels by PCR, in ameliorating liver disease and to some extent in achieving HBsAg seroconversion. This study aimed at assessing the virological and biochemical responses as well as breakthrough in HBeAg-negative chronic HBV (CHB) Egyptian patients receiving lamivudine therapy. Methods This retrospective study included 140 CHB patients with positive serum HBV-DNA by quantitative PCR assays and negative HBeAg who had never received prior anti-viral therapy for HBV. According to duration of lamivudine therapy (100 mg/day) patients were grouped into: group I (n=59) who received lamivudine for 1 year, group II (n=50) who received lamivudine for 2 years, and group III (n=31) who received lamivudine for 3 years. Results In group I, 76.3% patients had virologic response but this was reduced in group II and group III to 72% and 67.7% respectively. None of the patients in group I developed virologic breakthrough, whereas 12% and 25.8% in groups II and III respectively developed breakthrough. In group I, 25% of patients having high pre-treatment viremia showed virologic response compared to 84.6% and 83.3% having mild and moderate viremia respectively (P<0.01). However, in groups II and III, there was no significant relationship between pre-treatment viremia and virologic response. No significant relationship was found between pre-treatment viral load and incidence of breakthrough within each group. Conclusion Lamivudine remains one of the antiviral therapies for HBeAg negative CHB patients. The rates of maintained virologic and biochemical responses to lamivudine decrease in time due to selection of drug-resistant mutants and, hence, breakthrough. PMID:25331321

    Black-white differences in serum triglycerides and high-density lipoprotein (HDL) cholesterol concentrations are known. However, the metabolic basis for these differences is not clear. This study determined the magnitude of postprandial triglyceride concentrations, lipoprotein lipase and hepatic triglyceride lipase activities in postheparin plasma, and serum lipid and lipoprotein cholesterol concentrations in healthy young adult black men (n = 22) and white men (n = 28). Postprandial triglyceride concentrations were measured at 2, 3, 4, 5, 6, and 8 hours after a standardized test meal. Serum lipid and lipoprotein cholesterol concentrations were similar between the races in this study sample. However, incremental (above basal) increases in triglycerides were significantly greater in white men versus black men at 2 hours (P = .01) and tended to be greater at 3 hours (P = .12) and 4 hours (P = .06) after the fat load. In a multivariate analysis that included age, race, apolipoprotein E (apoE) genotype, fasting triglycerides, obesity measures, alcohol intake, and cigarette use, fasting triglycerides (P = .04) and, to a lesser extent, race (P = .07) were associated independently with the 2-hour incremental increase in triglycerides. The incremental triglyceride response correlated inversely with HDL cholesterol in both whites (r = -.38, P = .04) and blacks (r = -.59, P = .004). Lipoprotein lipase activity was higher (P = .049) and hepatic triglyceride lipase activity lower (P = .0001) in black men compared with white men; racial differences persisted after adjusting for the covariates. While lipoprotein lipase activity tended to associate inversely with the postprandial triglyceride concentration in both races, hepatic triglyceride lipase activity tended to correlate positively in whites and inversely in blacks. These results suggest that compared with whites, blacks may have an efficient lipid-clearing mechanism that could explain the black-white differences in

    Introducton: We studied the effect of dutasteride on the length of the off-treatment period in prostate cancer patients on intermittent androgen deprivation (IAD) therapy. Methods: We conducted a randomized, placebo-controlled Phase II trial in men with localized prostate cancer and a rising prostate-specific antigen (PSA) level post-primary treatment. Patients were randomized to dutasteride (0.5 mg/day) or placebo. All patients received androgen deprivation therapy (ADT), which was stopped at month 9 if the PSA level was <1.0 ng/mL. ADT was resumed when PSA increased to ≥5.0 ng/mL. End points included time off treatment, PSA nadir after 9 months of ADT, serum testosterone and dihydrotestosterone levels, and time to castrate-resistant prostate cancer (rising PSA while testosterone levels remain <50 ng/mL). Results: There were 87 evaluable patients: 49 dutasteride, 38 placebo. In total, 80 patients completed one treatment cycle: 45 dutasteride, 35 placebo. The median time off treatment for patients reaching ≥5 ng/mL was 18.6 and 16.7 months for dutasteride and placebo, respectively (p = 0.7600). The median PSA nadir at 9 months was 0.1 and 0.075 ng/mL, respectively (p = 0.4486). There were no cases of androgen-independent prostate cancer. Our study limitations include its short duration with only one treatment cycle evaluated. Conclusions: This small-scale Phase II randomized controlled trial showed no benefit to the addition of dutasteride to an IAD regimen. PMID:25485005

    Immunological responses to vaccination can differ depending on whether the vaccine is given alone or with other vaccines. This study was a retrospective evaluation of the immunogenicity of a tetravalent meningococcal conjugate vaccine for serogroups A, C, W, and Y (MenACWY) administered alone (n = 41) or concomitantly with other vaccines (n = 279) to U.S. military personnel (mean age, 21.6 years) entering the military between 2006 and 2008. Concomitant vaccines included tetanus/diphtheria (Td), inactivated polio vaccine (IPV), hepatitis vaccines, and various influenza vaccines, among others; two vaccine groups excluded Tdap and IPV. Immune responses were evaluated in baseline and postvaccination sera for Neisseria meningitidis serogroups C and Y 1 to 12 months (mean, 4.96 months) following vaccination. Functional antibodies were measured by using a serum bactericidal antibody assay with rabbit complement (rSBA) and by measurement of serogroup-specific immunoglobulin G (IgG) antibodies. The percentage of vaccinees reaching threshold levels (IgG concentration in serum, ≥2 μg/ml; rSBA titer, ≥8) corresponding to an immunologic response was higher postvaccination than at baseline (P < 0.001). Administration of MenACWY along with other vaccines was associated with higher geometric means of IgG concentrations and rSBA titers than those measured 4.60 months after a single dose of MenACWY. In addition, higher percentages of vaccinees reached the immunological threshold (range of odds ratios [ORs], 1.5 to 21.7) and more of them seroconverted (OR range, 1.8 to 4.8) when MenACWY was administered with any other vaccine than when administered alone. Additional prospective randomized clinical trials are needed to confirm the observed differences among groups in the immune response to MenACWY when given concomitantly with other vaccines to U.S. military personnel.

    Background: Blood-borne viruses such as hepatitis B, hepatitis C, and human immunodeficiency virus (HIV) have infected millions of people worldwide. During haircut or shaving, barbers may accidentally expose to their clients’ blood, transmit their own infection to them, or transmit the infection from one client to another. So the knowledge of barbers toward topics related to AIDS, hepatitis B, and C are of great importance. Materials and Methods: This cross-sectional descriptive study was performed in 2010–2011 in men's beauty salons in Isfahan town. A multistage sampling was performed. The knowledge assessment questionnaire and the checklist of practice regarding hepatitis B, C, and AIDS were completed by trained interviewers. Results: In our study, 240 hairdressers participated. There was a statistically significant relationship between the education level and knowledge score of the hairdressers (P = 0.048). We found a statistically significant relationship between the knowledge level and the working history of hairdressers according to the Pearson's correlation coefficient (P = 0.02). The results show significant relationship between the education level and the practice scores (P = 0.005). Also the working history of hairdressers and their practice score had a significant relationship (P = 0.005). The results did not show significant relationship between the age of the hairdressers and the practice scores (P = 0.12). Conclusions: We obtained promising results about the knowledge and practice levels of the staff of men's beauty shop in Isfahan about AIDS, hepatitis B, and C. However, but because of the important role of barbers in virus transmission, we should provide the best program for control, evaluation, continuous teaching programs. PMID:23326805

    We investigated whether there were racial/ethnic differences among young men who have sex with men (MSM) in their use of, perceived importance of, receipt of, and satisfaction with HIV prevention services received at health care providers (HCP) and HIV test providers (HTP) that explain racial disparities in HIV prevalence. Young men, aged 23 to 29 years, were interviewed and tested for HIV at randomly sampled MSM-identified venues in six U.S. cities from 1998 through 2000. Analyses were restricted to five U.S. cities that enrolled 50 or more black or Hispanic MSM. Among the 2,424 MSM enrolled, 1,522 (63%) reported using a HCP, and 1,268 (52%) reported having had an HIV test in the year prior to our interview. No racial/ethnic differences were found in using a HCP or testing for HIV. Compared with white MSM, black and Hispanic MSM were more likely to believe that HIV prevention services are important [respectively, AOR, 95% confidence interval (CI): 3.0, 1.97 to 4.51 and AOR, 95% CI: 2.7, 1.89 to 3.79], and were more likely to receive prevention services at their HCP (AOR, 95% CI: 2.5, 1.72 to 3.71 and AOR, 95% CI: 1.7, 1.18 to 2.41) and as likely to receive counseling services at their HTP. Blacks were more likely to be satisfied with the prevention services received at their HCP (AOR, 95% CI: 1.7, 1.14 to 2.65). Compared to white MSM, black and Hispanic MSM had equal or greater use of, perceived importance of, receipt of, and satisfaction with HIV prevention services. Differential experience with HIV prevention services does not explain the higher HIV prevalence among black and Hispanic MSM. PMID:18622708

    Purpose: To assess whether small prostate size is an adverse prognostic factor in men undergoing brachytherapy in the same manner in which it seems to be for men undergoing radical prostatectomy. Methods and Materials: From April 1995 to June 2008, 2024 patients underwent brachytherapy by a single brachytherapist. Median follow-up was 7.4 years. The role of small prostate size ({<=}20 cm{sup 3}) as a prognostic factor for biochemical progression-free survival, cause-specific survival, and all-cause mortality was investigated. The differences in survival between men with small and larger prostates were compared using Kaplan-Meier curves and log-rank tests. Results: Median prostate size for the entire cohort was 32.7 cm{sup 3}. For the 167 men with small prostates, median prostate size was 17.4 cm{sup 3}. There was no difference in biochemical progression-free survival (95.2% vs 96.2%, P=.603), cause-specific survival (97.7% vs 98.3%, P=.546), or all-cause mortality (78.0% vs 77.2%, P=.838) at 10 years for men with small prostates compared with men with larger prostates. On univariate and multivariate analysis, small prostate size was not associated with any of the primary outcome measures. Conclusion: Men with small prostates treated with brachytherapy have excellent outcomes and are at no higher risk of treatment failure than men with larger glands. High-quality implants with adequate margins seem sufficient to address the increased adverse risk factors associated with small prostate size.

    Background Newborns who have received hepatitis B immunization in 1980s are now young adults joining healthcare disciplines. The need for booster, pre- and post-booster checks becomes a practical question. Aims The aim of this study is to refine the HBV vaccination policy for newly admitted students in the future. Methods A prospective study on medical and nursing school entrants to evaluate hepatitis B serostatus and the response to booster doses among young adults. Findings Among 212 students, 17–23-year-old, born after adoption of neonatal immunization, 2 (0.9%) were HBsAg positive, 40 (18.9%) were anti-HBs positive. At 1 month after a single-dose booster for anti-HBs-negative students, 14.5% had anti-HBs <10 mIU/mL, 29.0% and 56.5% were 10–100 and >100 mIU/mL, respectively. The anti-HBs levels were significantly higher for females than males (mean [SD]: 431 [418] vs. 246 [339] mIU/mL, P = 0.047). At 2–4 month after the third booster dose, 97.1% had anti-HBs >100 mIU/mL and 2.9% had 10–100 mIU/mL. Conclusions Pre-booster check is still worthwhile to identify carriers among newly recruited healthcare workers born after adoption of neonatal immunization. A 3-dose booster, rather than a single dose, is required for the majority to achieve an anti-HBs level >100 mIU/mL, as memory immunity has declined in a substantial proportion of individuals. Cost-effectiveness of post-booster check for anti-HBs is low and should be further evaluated based on contextual specific utilization of results. PMID:25198289

    Before discussing Deep Space Network receivers, a brief description of the functions of receivers and how they interface with other elements of the Network is presented. Different types of receivers are used in the Network for various purposes. The principal receiver type is used for telemetry and tracking. This receiver provides the capability, with other elements of the Network, to track the space probe utilizing Doppler and range measurements, and to receive telemetry, including both scientific data from the onboard experiments and engineering data pertaining to the health of the probe. Another type of receiver is used for radio science applications. This receiver measures phase perturbations on the carrier signal to obtain information on the composition of solar and planetary atmospheres and interplanetary space. A third type of receiver utilizes very long baseline interferometry (VLBI) techniques for both radio science and spacecraft navigation data. Only the telemetry receiver is described in detail in this document. The integration of the Receiver-Exciter subsystem with other portions of the Deep Space Network is described.

    Kidney transplantation from hepatitis C virus (HCV)-positive donors to HCV-positive recipients has always been controversial regarding the safety and the outcomes. In the posttransplant period, treatment of hepatitis C with interferon-based regimens could lead to serious side effects. A patient with chronic hepatitis C and nephropathy, on dialysis, underwent renal transplantation from an HCV-positive donor and received direct-acting antiviral (DAA) drugs thereafter. His renal and liver functions, as well as the hepatitis C viral load, were evaluated at predetermined intervals throughout and after his treatment. Patient's viral load was undetectable 4, 12, and 24 weeks after initiation of his treatment. Renal and liver functions were maintained at baseline, with no evidence of transplant rejection. Our clinical case is one of the few examples in the medical literature that shows successful suppression of replication of HCV in an HCV-infected kidney transplant candidate who received within 2 months of listing a deceased donor kidney transplant from an HCV-infected donor. The recipient was treated with DAAs, and this case illustrates potential safety and efficacy of this approach. PMID:27597771

    The authors previously reported a fall in hepatic glucose output (HGO) during sleep accompanied by reductions in glucose utilization (Rd) and free fatty acids (FFAs). This study was undertaken to determine the potential role of changes in Rd and FFA on HGO in nondiabetic men. To determine if the fall in HGO during sleep could be reversed by FFA elevation, seven nondiabetic men underwent (3-3H)glucose infusions from 2200 to 0800, with heparin (90 mU.kg-1.min-1) added at 0200. Glucose appearance (Ra) fell from 11.7 {plus minus} 1.1 at 2430 to 8.9 {plus minus} 0.8 mumol.kg-1.min-1 (P less than 0.05) at 0200. The fall in Ra was associated with decreases in FFA (0.57 {plus minus} 0.10 to 0.48 {plus minus} 0.07 mM) and glycerol (0.08 {plus minus} 0.01 to 0.06 {plus minus} 0.01 mM). Infusion of heparin significantly increased FFA and glycerol (1.09 {plus minus} 0.21 and 0.11 {plus minus} 0.01 mM, respectively, P less than 0.01) and resulted in a significant fall in plasma alanine, suggesting that gluconeogenesis had been increased. However, rates of glucose turnover were indistinguishable from overnight studies without heparin. In additional studies (n = 6), intralipid and heparin-induced FFA elevation (from 0.61 {plus minus} 0.07 to 0.95 {plus minus} 0.05 mM, P less than 0.01) stimulated gluconeogenesis ((U-14C)alanine to glucose) twofold (188 {plus minus} 22% increase compared to 114 {plus minus} 6% in saline control studies, P less than 0.01). However, despite increasing gluconeogenesis, overall HGO did not change (10.6 {plus minus} 0.5 vs. 10.7 {plus minus} 0.6 mumol.kg-1.min-1) during lipid infusion.

    BACKGROUND: Internationally, there is a growing recognition that hepatitis C virus (HCV) may be sexually transmitted among HIV-positive men who have sex with men (MSM). OBJECTIVE: To report the first Canadian estimate of HCV seroincidence in 2000 to 2010 and its risk factors among HIV-positive MSM with no known history of injection drug use. METHODS: Data from the Ontario HIV Treatment Network Cohort Study, an ongoing cohort of individuals in HIV care in Ontario, were analyzed. Data were obtained from medical charts, interviews and record linkage with the provincial public health laboratories. The analysis was restricted to 1534 MSM who did not report injection drug use and had undergone ≥2 HCV antibody tests, of which the first was negative (median 6.1 person-years [PY] of follow-up; sum 9987 PY). RESULTS: In 2000 to 2010, 51 HCV seroconversions were observed, an overall incidence of 5.1 per 1000 PY (95% CI 3.9 to 6.7). Annual incidence varied from 1.6 to 8.9 per 1000 PY, with no statistical evidence of a temporal trend. Risk for seroconversion was elevated among men who had ever had syphilis (adjusted HR 2.5 [95% CI 1.1 to 5.5) and men who had acute syphilis infection in the previous 18 months (adjusted HR 2.8 [95% CI 1.0 to 7.9]). Risk was lower for men who had initiated antiretroviral treatment (adjusted HR 0.49 [95% CI 0.25 to 0.95]). There were no statistically significant effects of age, ethnicity, region, CD4 cell count or HIV viral load. CONCLUSIONS: These findings suggest that periodic HCV rescreening may be appropriate in Ontario among HIV-positive MSM. Future research should seek evidence whether syphilis is simply a marker for high-risk sexual behaviour or networks, or whether it potentiates sexual HCV transmission among individuals with HIV.

    Background: The ultimate goal of hepatitis B treatment is hepatitis B surface antigen (HBsAg) seroclearance. Several factors have been suggested to be associated with the rate of HBsAg reduction in antiviral-naive or lamivudine therapy cohorts. However, there are few studies evaluating the factors during long-term entecavir (ETV) therapy. In the present study, we aimed to evaluate the factors to predict the outcome of ETV therapy for 7 years. Methods: A total of 47 chronic hepatitis B (CHB) patients treated with ETV monotherapy were included in this study. Liver biochemistry, hepatitis B virus (HBV) serological markers, serum HBV DNA, and HBsAg titers were tested at baseline, 3 months, 6 months, and yearly from 1 to 7. The associations between factors and HBsAg reduction were assessed using multivariate tests with repeated measure analysis of variance. Results: At baseline, serum HBsAg levels showed a positive correlation with baseline HBV DNA levels (r = 0.625, P < 0.001). The mean HBsAg titers after ETV treatment were significantly lower than the baseline titers (P ranges from 0.025 to 0.000,000,6). The HBsAg reduction rate during the 1st year was greater compared to after 1 year of treatment (P < 0.05). Multivariate test showed that hepatitis B e antigen (HBeAg) seroclearance and/or HBsAg reduction ≥0.5 log10 IU/ml at 6 months had a high negative predictive value (96.77%) for HBsAg seroclearance (P = 0.002, P = 0.012, respectively). Conclusions: The HBsAg reduction rate during the 1st year was greater than that after 1 year of treatment. Further, HBeAg status and HBsAg levels at month 6 are the optimal factors for the early prediction of HBsAg seroclearance after long-term ETV therapy in CHB patients. PMID:27064037

  13. Prevalence of hepatitis C in a Swiss sample of men who have sex with men: whom to screen for HCV infection?

    2014-01-01

    Background While the numbers of hepatitis-C-virus (HCV) infections among men who have sex with men (MSM) who are co-infected with the human immunodeficiency virus (HIV) are on the rise, with vast evidence for sexual transmission of HCV in this population, concerns have also been raised regarding sexual HCV-transmission among MSM without HIV infection. Therefore, the aim of this study was to estimate the prevalence of hepatitis C among MSM without HIV diagnosis in Zurich (Switzerland). Methods Participants were recruited from a gay health centre and various locations such as dark rooms, saunas and cruising areas in Zurich. Participants self-completed a questionnaire assessing known and suspected risk factors for HCV-infection, and provided a blood sample for detection of past (antibodies) and present (core antigen, RNA) infections with HCV. Results In total, 840 MSM aged 17-79 (median: 33 years) underwent HCV-testing and completed the questionnaire, among whom 19 reported living with HIV. Overall, seven tested positive for HCV-antibodies, and two were also positive for HCV core antigen and HCV-RNA–these two were immigrants, one from a country where HCV is endemic. None of the seven were aware of their infection. The seroprevalence of hepatitis C among the 821 non-HIV-diagnosed MSM was 0.37% (95%-CI: 0.12-1.69%), and one man harboured replicating virus (0.12%; 0.02-0.69%), resulting in a number needed to test of 821 to detect one active infection. Significant univariable associations of lifetime HCV-infection were found with known HIV-diagnosis (OR=72.7), being tattooed (OR=10.4), non-injection use of cocaine/amphetamines (OR=8.8), and non-Swiss origin (OR=8.5). For MSM without HIV-diagnosis, the only variable marginally associated with positive HCV-serostatus was being tattooed (OR=8.3). No significant associations were observed with reported injection drug use, unprotected anal intercourse, sexual practices that may lead to mucosal trauma, or proxy measures for

    Background We aimed to determine the incidence of Hepatitis C (HCV) infection among HIV-infected men who have sex with men (MSM) attending a Sexual Health Centre. Methods A retrospective cohort study was carried out among HIV-infected MSM seen at least once between February 2002 and March 2010. The analysis was restricted to MSM who had had a negative HCV antibody test at least 6 months after their diagnosis for HIV. Duration of follow up was taken from the date of HIV diagnosis to the first positive or last negative HCV antibody test. Results During the time 1445 HIV-infected men attended the clinic of whom 1065 (74%) were MSM. Of these, 869 (82%) were tested for HCV at any time after HIV diagnosis. Of these 869, 69% (620) tested HCV negative at least 6 months after their HIV diagnosis. These 620 men had a mean age of 34 years (range 17-72) at HIV diagnosis and a total of 4,359 person years (PY) of follow up. There were 40 incident cases of HCV, of which 16 were in injecting drug users (IDU) and 24 in non-IDU. The overall incidence of HCV among HIV-infected MSM was 0.9/100 PY (95% CI 0.6-1.2). The incidence among HIV-infected IDU was 4.7/100 PY (95% CI 2.7-7.5) while the incidence among HIV-infected non-IDU was 0.6/100 PY (95% CI 0.4-0.8) (hazard ratio of 8.7 and 95% CI 4.6-16.6, P < 0.001). The majority (78%) were tested for HCV because they developed abnormal liver transaminases (n = 31) or hepatitis symptoms (n = 2), while others (n = 7) were identified through routine HCV testing. Conclusion A considerable proportion of HIV-positive MSM who did not inject drugs contracted HCV, presumably via sexual transmission and the main trigger for investigation was abnormal liver transaminases.

    Five Human Immunodeficiency Virus (HIV) seropositive homosexually active men experienced hepatitis C-seroconversion in the period between September 2004 and January 2007 at a single HIV Reference Center (University Hospital Ghent, Belgium). There was no history of intravenous drug use. All had unprotected anal sex with multiple other HIV seropositive men in the recent past. All of them had clinical syphilis and/or lymphogranuloma venereum rectitis within three to six months before the hepatitis C-seroconversion was detected. This confirms the observations in other case reports and studies originating from the Netherlands, France, the United Kingdom and Germany, illustrating sexual transmission of hepatitis C virus (HCV) infection in this high-risk group. Physicians should be aware of the persistent high-risk behaviour in a subgroup of HIV seropositive homosexually active men and perform intensive sexual counselling and screening for other sexually transmitted diseases, including HCV, during medical follow-up.

    Accurate evaluation of the degree of liver fibrosis in patients with chronic liver diseases (CLD) is crucial, as liver fibrosis is important in determining the prognosis of liver diseases. Currently, liver biopsy (LB) is considered the gold standard for staging liver fibrosis or cirrhosis. However, utilization of LB in clinical practice is often limited because of its invasive nature, sampling error and interobserver variability. Recently, transient elastography (TE) was introduced as a noninvasive, highly reproducible technique for assessing the degree of liver fibrosis. After extensive studies, TE is now regarded as a reliable surrogate marker for grading the severity of liver fibrosis in patients with CLD. In the past few years, the role of TE in monitoring liver stiffness and determining prognosis in patients with chronic hepatitis B (CHB) or chronic hepatitis C (CHC) who are undergoing antiviral treatment has been investigated. In patients with CHB, liver stiffness values decrease with antiviral treatment. TE can also be used to predict the incidence of liver-related events during antiviral treatment. In patients with CHC, TE can be used to monitor potential regression of liver fibrosis after antiviral treatment and may predict the treatment outcome of CHC. In addition, TE is an adjunct tool for distinguishing inactive hepatitis B virus carriers from patients with chronic active hepatitis. This review article discusses the important findings from recent studies focusing on the clinical application of TE in patients with chronic viral hepatitis who are undergoing antiviral treatments.

    Objectives To investigate the impact of metabolic components and body composition indices on prostate volume (PV) in a population of middle-aged men receiving health check-ups. Methods Six hundred and sixteen men receiving health assessments were stratified to large and small prostates based on the cut-off of median PV. Their demographic data, health history, and international prostate symptoms scores (IPSS) were collected. Metabolic components and body composition indices were compared between subjects with large and small prostates. Moreover, the correlations between these parameters and PV were analyzed by multivariate logistic regression. Results The median PV was 27 mL and mean age was 54.8 years. Subjects with large PV were older (56.5 vs. 52.7 years) and had higher serum prostate specific antigen (PSA) level (1.73 vs. 0.96 ng/mL), higher IPSS score (8.37 vs. 6.16), and higher body fat, body mass, and waist circumference (all p<0.05). In multivariate analysis, age (OR, 2.45; 95%CI, 1.74–3.45), serum PSA (OR, 2.75; 95%CI, 1.96–3.86), waist circumference (OR, 1.45; 95%CI, 1.02–2.07), fatness (OR, 1.47; 95%CI, 1.04–2.09), and body fat mass (OR, 1.43; 95%CI, 1.00–2.03) were significantly correlated with PV of study subjects. In subgroup analysis, raised waist circumference (OR, 1.89; 95%CI, 1.00–3.59) was the independent predictor of PV in subjects with bothersome lower urinary tract symptoms. Conclusions Several metabolic components and body composition indices are significantly associated with PV of middle-aged men, including raised waist circumference, fatness, and body fat mass. Raised waist circumference is the only independent predictor of PV in middle-aged men with bothersome LUTS. PMID:26731481

    Background. Since 2000, incidence of sexually acquired hepatitis C virus (HCV)-infection has increased among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). To date, few case-control and cohort studies evaluating HCV transmission risk factors were conducted in this population, and most of these studies were initially designed to study HIV-related risk behavior and characteristics. Methods. From 2009 onwards, HIV-infected MSM with acute HCV infection and controls (HIV-monoinfected MSM) were prospectively included in the MOSAIC (MSM Observational Study of Acute Infection with hepatitis C) study at 5 large HIV outpatient clinics in the Netherlands. Written questionnaires were administered, covering sociodemographics, bloodborne risk factors for HCV infection, sexual behavior, and drug use. Clinical data were acquired through linkage with databases from the Dutch HIV Monitoring Foundation. For this study, determinants of HCV acquisition collected at the inclusion visit were analyzed using logistic regression. Results. Two hundred thirteen HIV-infected MSM (82 MSM with acute HCV infection and 131 MSM without) were included with a median age of 45.7 years (interquartile range [IQR], 41.0–52.2). Receptive unprotected anal intercourse (adjusted odds ratio [aOR], 5.01; 95% confidence interval [CI], 1.63–15.4), sharing sex toys (aOR, 3.62; 95% CI, 1.04–12.5), unprotected fisting (aOR, 2.57; 95% CI, 1.02–6.44), injecting drugs (aOR, 15.62; 95% CI, 1.27–192.6), sharing straws when snorting drugs (aOR, 3.40; 95% CI, 1.39–8.32), lower CD4 cell count (aOR, 1.75 per cubic root; 95% CI, 1.19–2.58), and recent diagnosis of ulcerative sexually transmitted infection (aOR, 4.82; 95% CI, 1.60–14.53) had significant effects on HCV acquisition. Conclusions. In this study, both sexual behavior and biological factors appear to independently increase the risk of HCV acquisition among HIV-infected MSM. PMID:26634219

Receptive unprotected anal intercourse (adjusted odds ratio [aOR], 5.01; 95% confidence interval [CI], 1.63-15.4), sharing sex toys (aOR, 3.62; 95% CI, 1.04-12.5), unprotected fisting (aOR, 2.57; 95% CI, 1.02-6.44), injecting drugs (aOR, 15.62; 95% CI, 1.27-192.6), sharing straws when snorting drugs (aOR, 3.40; 95% CI, 1.39-8.32), lower CD4 cell count (aOR, 1.75 per cubic root; 95% CI, 1.19-2.58), and recent diagnosis of ulcerative sexually transmitted infection (aOR, 4.82; 95% CI, 1.60-14.53) had significant effects on HCV acquisition. Conclusions.  In this study, both sexual behavior and biological factors appear to independently increase the risk of HCV acquisition among HIV-infected MSM. PMID:26634219

    The rare hepatitis B virus (HBV) genotype G (HBV/G) coinfects HIV-1-positive individuals along with HBV/A and generates recombinants. However, the circulation of HBV A/G recombinants remains poorly understood. This molecular epidemiologic study examined HBV A/G recombinants in Japanese HIV-1-positive men who have sex with men (MSM). Initially, blood specimens submitted for confirmatory tests of HIV infection in Osaka and Tokyo, Japan, from 2006 to 2013 were examined for HIV-1, and HIV-1-positive specimens were screened for HBV. Among 817 specimens from HIV-1-positive individuals, HBsAg was detected in 59 specimens; of these, HBV/Ae (alternatively A2), a subgenotype of HBV/A prevalent in Europe and North America, was identified in 70.2%, HBV/C in 17.5%, and HBV/G in 10.5%, and HBV/E in 1.8% according to the core gene sequence. The full-length genome analysis of HBV was performed on HBV/G-positive specimens because some HBV A/G recombinants were historically overlooked by genotyping based on a partial genome analysis. It revealed that five of the specimens contained novel Ae/G recombinants, the core gene of which had a high sequence similarity to HBV/G. Detailed analyses showed that novel recombinants were coinfected with HBV/Ae in a recombinant-dominant fashion. No major drug-resistant mutations were found in the newly identified HBV Ae/G recombinants. Some of the individuals asymptomatically coinfected with HIV/HBV suffered mild liver injury. This study demonstrated that novel Ae/G HBV recombinants were identified in Japanese HIV-1-positive MSM. The pathogenicity of novel HBV Ae/G recombinants should be examined in a future longitudinal study. Surveillance of such viruses in HIV-1-positive individuals should be emphasized. PMID:25825936

    The aim of this study was to characterize the current molecular epidemiology of hepatitis C virus (HCV) infection and evaluate the evolutionary patterns of HCV subtypes in Beijing, China, among different subpopulations.The whole blood samples and behavioral data were collected from a total of 10,354 subjects, including drug users (DUs), men who have sex with men (MSM), and the general population, in Beijing from 2010 to 2011. Samples were tested for HCV infection using both enzyme-linked immunosorbent assay (ELISA) and real-time PCR. All viremic subjects were then sequenced by nested PCR over core/E1 and NS5B regions. Phylogenetic and phylogeographic analysis was performed by BEAST software.In total, 217 subjects (2.1%) were tested positive for HCV by antibody or vRNA-based testing. HCV prevalence rates for DUs, MSM, and the general population were 26.2%, 0.54%, and 0.37%, respectively. The 156 HCV RNA-positive samples were sequenced. Nine HCV genotypes, including 1a, 1b, 2a, 3a, 3b, 6a, 6n, 6u and 6v, were detected. The most prevalent subtypes were 3b (36.09%), 1b (32.54%), and 3a (16.57%). Bayesian evolutionary analysis estimated that the time of introduction of subtype 1b into Beijing was 2004 (95% CI: 1997.7, 2007.7), with subtypes 3a and 3b being introduced later in 2006. Evolutionary analyses further suggested that subtype 1b from Beijing and Shanghai were closely related, whereas subtype 3a sequences were more similar with sequences from Yunnan, Guangzhou, Hong Kong, and Jiangsu. Subtype 3b sequences were closely related to those from Yunnan, Guangdong, and Hong Kong.Thus, the current HCV epidemic in Beijing is complex, heavily affecting DUs, and involving multiple genotypes that likely spread from different regions in China with its large migrant population.

    Objective To compare the characteristics associated with hepatitis C virus (HCV) antibody (anti-HCV) prevalence and HCV clearance between injection drug using (IDU) and non-IDU men who have sex with men (MSM). Methods Stored serum and plasma samples were tested for anti-HCV and HCV RNA to determine the HCV status of 6925 MSM at enrollment into the Multicenter AIDS Cohort Study (MACS). Prevalence and clearance ratios (PR and CR) were calculated to determine the characteristics associated with HCV prevalence and clearance. Multivariable analyses were performed using Poisson regression methods with robust variance estimation. Results Anti-HCV prevalence was significantly higher among IDU than non-IDU MSM (42.9% vs. 4.0%) while clearance was significantly lower among IDU MSM (11.5% vs. 34.5% among non-IDU MSM). HIV infection, Black race, and older age were independently associated with higher prevalence in both groups while smoking, transfusion history, and syphilis were significantly associated with prevalence only among non-IDU MSM. The rs12979860-C/C genotype was the only characteristic independently associated with HCV clearance in both groups, but the effects of both rs12979860-C/C genotype (CR=4.16 IDUs vs. 1.71 non-IDUs; p=0.03) and HBsAg positivity (CR=5.06 IDUs vs. 1.62 non-IDUs; p=0.03) were significantly larger among IDU MSM. HIV infection was independently associated with lower HCV clearance only among non-IDU MSM (CR=0.59, 95% CI=0.40–0.87). Conclusions IDU MSM have higher anti-HCV prevalence and lower HCV clearance than non-IDU MSM. Differences in the factors associated with HCV clearance suggest that the mechanisms driving the response to HCV may differ according to the mode of acquisition. PMID:25280229

    Background Hepatitis C virus (HCV) emerged as sexually transmitted infection among HIV-infected men who have sex with men (MSM). We studied whether HCV circulated in identifiable high-risk MSM subcultures and performed phylogenetic analysis. Methods HIV-infected MSM were recruited at the sexually transmitted infections (STI) outpatient clinic and a university HIV clinic in Amsterdam, the Netherlands, 2008–2009. Participants completed a detailed questionnaire and were tested for HCV antibodies and RNA, with NS5B regions sequenced for analysis of clusters. Results Among 786 participants, the median age was 43 (IQR 37–48) years, and 93 (11.8%) were HCV-positive. Seropositivity was associated with belonging to subcultures identified as leather (aOR 2.60; 95% CI 1.56–4.33), rubber/lycra (aOR 2.15; 95% CI 1.10–4.21), or jeans (aOR 2.23; 95% CI 1.41–3.54). The two largest HCV-RNA monophyletic clusters were compared; MSM in cluster I (genotype 1a, n = 13) reported more partners (P = 0.037) than MSM in cluster II (genotype 4d, n = 14), but demographics, subculture characteristics and other risk behaviors did not differ significantly between the two clusters. Discussion HCV infection is associated with identifiable groups of leather/rubber/lycra/jeans subcultures among HIV-infected MSM. Separate epidemiological HCV transmission networks were not revealed. Active HCV screening and treatment within specific subcultures may reduce HCV spread among all MSM. PMID:23469226

    Background Men with prostate cancer are at risk of experiencing accelerated bone loss and fractures as a result of androgen deprivation therapy (ADT). Objective We evaluated the effects of denosumab, a fully human monoclonal antibody against RANKL, on preservation of BMD at 3 key skeletal sites (lumbar spine [LS], femoral neck [FN], and total hip [TH]) and the distal radius at 36 months both by responder category and individual responses in a waterfall plot analysis. Design, Setting, and Participants This phase 3, randomized, double-blind study of men with non-metastatic prostate cancer receiving ADT investigated the effects of denosumab on bone mineral density (BMD) and fractures. Patients were treated for 36 months. Intervention Subcutaneous denosumab 60 mg (n=734) or placebo (n=734) every 6 months for up to 36 months. Patients were instructed to take supplemental Calcium and vitamin D. Measurements Primary outcome measure: The percentage change from baseline to month 36 in LS, FN, and TH BMD was measured by dual energy x-ray absorptiometry. BMD at the distal 1/3 radius at 36 months was measured in a sub-study of 309 patients. Results and Limitations At 36 months, significantly more patients in the denosumab arm had increases of >3% BMD from baseline at each site studied compared with placebo (LS, 78% vs 17%; TH, 48% vs 6%; FN, 48% vs 13%; distal 1/3 radius, 40% vs 7%). The percentage of denosumab patients with bone loss at all 3 key BMD sites at month 36 was 1%, as opposed to 42% in placebo arm. At 36 months 69% of denosumab-treated patients had BMD increases at all three sites (LS, TH or FN) compared with 8% of placebo-treated patients. Lower baseline BMD was associated with higher magnitude lumbar spine, femoral neck, and total hip BMD responses to denosumab. Conclusions In men with prostate cancer receiving ADT significantly higher BMD response rates were observed with denosumab vs. placebo. Trial Registration This study is registered with Clinical

    The use of rituximab has been associated with increased risk of hepatitis B virus (HBV) reactivation in patients who are hepatitis B surface antigen (HBsAg) negative and antihepatitis B core antibody (anti-HBc) positive. We aim to determine the rate of HBV reactivation in this group of patients who received rituximab-containing combination chemotherapy without concomitant antiviral prophylaxis and to identify potential risk factors for reactivation. Sixty-two HBsAg negative/anti-HBc positive patients with B-cell lymphoma treated with rituximab-based immunochemotherapy from 2006 to 2009 were included. None of the patients received concomitant antiviral prophylaxis. In this cohort, 48 (77%) patients received rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP), eight (13%) received rituximab with cyclophosphamide, vincristine and prednisolone, and six (10%) received other chemotherapy regimens. Two patients suffered HBV reactivation; both were above 70 years of age, received R-CHOP chemotherapy and were negative for antihepatitis B surface antibody (anti-HBs) at baseline. One of the two patients reactivated shortly after completion of R-CHOP chemotherapy while the other reactivated during rituximab maintenance treatment. Thus, the overall reactivation rate in this cohort of patients is 3% (2/62), 4% (2/48), and 25% (1/4) in patients who received R-CHOP chemotherapy and who received rituximab maintenance, respectively. The rate of HBV reactivation is low in patients who are HBsAg negative/anti-HBc positive receiving rituximab-based combination chemotherapy without concomitant antiviral prophylaxis. However, elderly patients, particularly those without anti-HBs, seemed particularly at risk. PMID:21520001

    Objective In this Phase 2 multicenter study the efficacy and safety of oral abiraterone acetate (1000 mg/once daily) plus prednisolone (5 mg/twice daily) was evaluated in metastatic castration-resistant prostate cancer patients from Japan who had previously received docetaxel-based chemotherapy. Methods Men (aged ≥20 years) with metastatic castration-resistant prostate cancer (prostate-specific antigen levels: ≥5 ng/ml), who had received 1 or 2 cytotoxic chemotherapies (with ≥1 regimen being docetaxel) for prostate cancer, were enrolled in this open-label, single-arm study. Primary efficacy endpoint was proportion of patients achieving a ≥50% prostate-specific antigen decline from baseline (prostate-specific antigen response rate) after 12-week treatment. Safety and pharmacokinetics were also assessed. Results Confirmed prostate-specific antigen response rate by Week 12 was 28.3% (90% confidence interval: 17.6%; 41.1%) or 13 out of 46 (full analysis set) treated patients. However, total prostate-specific antigen response rate including confirmed and unconfirmed responses was 34.8% (90% confidence interval: 23.2%; 47.9%). Secondary efficacy endpoints and outcomes were: improvement in Eastern Cooperative Oncology Group performance status score by ≥1 unit: 7/16 patients (43.8%); objective radiographic response: complete response, partial response and stable disease in 0, 1/22 (4.5%) and 9/22 (40.9%) patients, respectively; pain palliation response: 9/16 (56.3%) patients. The most common adverse events (>20% patients) were upper respiratory tract infection (13/47, 27.7% patients) and hepatic function abnormal (10/47, 21.3% patients, Grade 3: 8.5%). All mineralocorticoid-related toxicities were Grade 1/2. Conclusions Abiraterone acetate plus prednisolone showed favorable efficacy in metastatic castration-resistant prostate cancer Japanese patients who had received chemotherapy. Abiraterone acetate plus prednisolone had an acceptable safety profile. Clinical

    Background Hepatitis B virus (HBV) is an important cause of comorbidity in human immunodeficiency virus (HIV)–infected individuals. The immunogenicity of HBV vaccination in children receiving highly active antiretroviral therapy (HAART) was investigated. Methods HIV-infected children receiving HAART who had low to moderate HIV loads and who had previously received ≥3 doses of HBV vaccine were given an HBV vaccine booster. Concentrations of antibody to hepatitis B surface antigen (anti-HBs) were determined before vaccination and at weeks 8, 48, and 96. A subset of subjects was administered a subsequent dose, and anti-HBs was measured before and 1 and 4 weeks later. Results At entry, 24% of 204 subjects were seropositive. Vaccine response occurred in 46% on the basis of seropositivity 8 weeks after vaccination and in 37% on the basis of a ≥4-fold rise in antibody concentration. Of 69 subjects given another vaccination 4–5 years later, immunologic memory was exhibited by 45% on the basis of seropositivity 1 week after vaccination and by 29% on the basis of a ≥4-fold rise in antibody concentration at 1 week. Predictors of response and memory included higher nadir and current CD4 cell percentage, higher CD19 cell percentage, and undetectable HIV load. Conclusions HIV-infected children frequently lack protective levels of anti-HBs after previous HBV vaccination, and a significant proportion of them do not respond to booster vaccination or demonstrate memory despite receiving HAART, leaving this population insufficiently protected from infection with HBV.

    2013-01-01

    Since 2001, cases of hepatitis C virus (HCV) sexual transmission have been reported in France, among HIV-positive gay men who do not inject drugs. An earlier study focused on the incidence of acute hepatitis C and risk factors associated with HCV transmission. The present study, based on in-depth interviews, aimed to highlight the biography, the sexual practices and the experiences of gay men infected with HCV. Beyond an apparent uniformity, the group of interviewees illustrates a variety of situations, life stories and health pathways, depending on their age. These well-adjusted gay men were used to engaging in unprotected sexual practices, but before their diagnosis they largely ignored HCV-transmission risk, which was associated in their mind with a pejorative drug addict image. Once diagnosed with acute hepatitis C, they experienced a critical and emotional period during which they were open to discuss their sexual practices and reconsider risk-reduction procedures, without being willing to give up on their satisfying sex life. Health educators should consider labelling hepatitis C as an STI in order to disrupt its negative image and to help HIV-positive gay man raise their awareness of HCV-transmission risks and implement better risk-reduction strategies.

    Objective: To report late toxicity outcomes from a randomized trial comparing conventional and hypofractionated prostate radiation therapy and to identify dosimetric and clinical parameters associated with late toxicity after hypofractionated treatment. Methods and Materials: Men with localized prostate cancer were enrolled in a trial that randomized men to either conventionally fractionated intensity modulated radiation therapy (CIMRT, 75.6 Gy in 1.8-Gy fractions) or to dose-escalated hypofractionated IMRT (HIMRT, 72 Gy in 2.4-Gy fractions). Late (≥90 days after completion of radiation therapy) genitourinary (GU) and gastrointestinal (GI) toxicity were prospectively evaluated and scored according to modified Radiation Therapy Oncology Group criteria. Results: 101 men received CIMRT and 102 men received HIMRT. The median age was 68, and the median follow-up time was 6.0 years. Twenty-eight percent had low-risk, 71% had intermediate-risk, and 1% had high-risk disease. There was no difference in late GU toxicity in men treated with CIMRT and HIMRT. The actuarial 5-year grade ≥2 GU toxicity was 16.5% after CIMRT and 15.8% after HIMRT (P=.97). There was a nonsignificant numeric increase in late GI toxicity in men treated with HIMRT compared with men treated with CIMRT. The actuarial 5-year grade ≥2 GI toxicity was 5.1% after CIMRT and 10.0% after HIMRT (P=.11). In men receiving HIMRT, the proportion of rectum receiving 36.9 Gy, 46.2 Gy, 64.6 Gy, and 73.9 Gy was associated with the development of late GI toxicity (P<.05). The 5-year actuarial grade ≥2 GI toxicity was 27.3% in men with R64.6Gy ≥ 20% but only 6.0% in men with R64.6Gy < 20% (P=.016). Conclusions: Dose-escalated IMRT using a moderate hypofractionation regimen (72 Gy in 2.4-Gy fractions) can be delivered safely with limited grade 2 or 3 late toxicity. Minimizing the proportion of rectum that receives moderate and high dose decreases the risk of late rectal toxicity after this

  15. Hepatitis C virus infection among HIV-positive men who have sex with men: protocol for a systematic review and meta-analysis

    PubMed Central

    2014-01-01

    Background Outbreaks of hepatitis C virus (HCV) infection have been reported in HIV-positive men who have sex with men (MSM) in North America, Europe and Asia. Transmission is believed to be the result of exposure to blood during sexual contact. In those infected with HIV, acute HCV infection is more likely to become chronic, treatment for both HIV and HCV is more complicated and HCV disease progression may be accelerated. There is a need for systematic reviews and meta-analyses to synthesize the epidemiology, prevention and methods to control HCV infection in this population. Methods/design Eligible studies will include quantitative empirical data related to sexual transmission of HCV in HIV-positive MSM, including data describing incidence or prevalence, and associations between risk factors or interventions and the occurrence or progression of HCV disease. Care will be taken to ensure that HCV transmission related to injection drug use is excluded from the incidence estimates. Scientific databases will be searched using a comprehensive search strategy. Proceedings of scientific conferences, reference lists and personal files will also be searched. Quality ratings will be assigned to each eligible report using the Newcastle–Ottawa scale. Pooled estimates of incidence rates and measures of association will be calculated using random effects models. Heterogeneity will be assessed at each stage of data synthesis. Discussion HIV-positive MSM are a key HCV-affected population in the US and other high-income countries. This review seeks to identify modifiable risk factors and settings that will be the target of interventions, and will consider how to constitute a portfolio of interventions to deliver the greatest health benefit. This question must be considered in relation to the magnitude of HCV infection and its consequences in other key affected populations, namely, young prescription opioid users who have transitioned to illicit opiate injection, and older

    This cross-sectional study assessed predictors of Hepatitis C Virus (HCV) positivity with baseline data collected on recently-released male parolees (N=157) participating in a randomized trial focused on reduction of drug use, recidivism and risk for hepatitis and HIV infections. In this sample, the prevalence of HCV was 25%. The logistic regression analysis revealed that being an injection drug user (IDU) was significantly related to HCV infection. However, contrary to most of the current literature, being African American had significantly lower odds of contracting HCV than their Caucasian counterparts. Moreover, having lived on the streets, not being part of a close family in childhood and being older were also associated with HCV infection. These findings highlight the need for skilled assessments that target the vulnerabilities of homeless adults, especially those who have been incarcerated. Understanding drug use patterns, childhood networks, and family relationships, may assist in the design of interventions to reduce risky drug use and address behaviors derived from disadvantaged childhood.

    We explored anticipated and actual reactions to receiving HIV positive results through self-testing with a diverse group of 84 gay and bisexual men in New York City. Grounded Theory was used to investigate these reactions in a two-phase study, one hypothetical, followed by a practical phase in which self-tests were distributed and used. Three major themes emerged when participants were asked about their anticipated reactions to an HIV positive self-test result: managing emotional distress, obtaining HIV medical care, and postponing sexual activity. When participants were asked about their anticipated reactions to a partner's HIV positive self-test result, five themes emerged: provide emotional support; refrain from engaging in sex with casual partner; avoid high-risk sexual activity with both main and casual partners; seek medical services; and obtain a confirmatory test result. Although none of the participants tested positive, seven of their partners did. Participants provided emotional support and linked their partners to support services. The availability of HIV self-testing kits offers potential opportunities to tackle HIV infection among individuals with high-risk practices. PMID:24858480

    A recent study revealed that quantitative hepatitis B core antibody (qAnti-HBc) level could serve as a novel marker for predicting treatment response. In the present study, we further investigated the predictive value of qAnti-HBc level in HBeAg-positive patients undergoing PEG-IFN therapy. A total of 140 HBeAg-positive patients who underwent PEG-IFN therapy for 48 weeks and follow-up for 24 weeks were enrolled in this study. Serum samples were taken every 12 weeks post-treatment. The predictive value of the baseline qAnti-HBc level for treatment response was evaluated. Patients were further divided into 2 groups according to the baseline qAnti-HBc level, and the response rate was compared. Additionally, the kinetics of the virological and biochemical parameters were analyzed. Patients who achieved response had a significantly higher baseline qAnti-HBc level (serological response [SR], 4.52±0.36 vs. 4.19±0.58, p=0.001; virological response [VR], 4.53±0.35 vs. 4.22±0.57, p=0.005; combined response [CR], 4.50±0.36 vs. 4.22±0.58, p=0.009)). Baseline qAnti-HBc was the only parameter that was independently correlated with SR (p=0.008), VR (p=0.010) and CR(p=0.019). Patients with baseline qAnti-HBc levels ≥30,000 IU/mL had significantly higher response rates, more HBV DNA suppression, and better hepatitis control in PEG-IFN treatment. In conclusion, qAnti-HBc level may be a novel biomarker for predicting treatment response in HBeAg-positive patients receiving PEG-IFN therapy. PMID:25553110

    The scavenger receptor type B class I(SR-BI) is a receptor for high-density lipoproteins(HDL) and one of entry factors for hepatitis C virus(HCV). We examined the association of single nucleotide polymorphisms(SNPs) of the SCARB1 gene, which encodes SR-BI, with virologic responses to pegylated interferon-based treatment in Asian chronic hepatitis C(CHC) patients. Human genomic and clinical data were collected from 156 consecutive Taiwanese HCV genotype 1 or 2 patients who received pegylated interferon plus ribavirin therapy and 153 non-HCV healthy subjects. Three SNPs(rs10846744, rs5888, and rs3782287) of the SCARB1 gene that have been linked to humans diseases were investigated. rs10846744 rather than rs5888 or rs3782287 was associated with serum HCV RNA level and sustained virologic response(SVR) to pegylated interferon plus ribavirin therapy in CHC patients(GG vs. non-GG genotype, Adjusted Odds Ratio, 95% CI: 0.32, 0.11–0.95, P = 0.039). Among patients with IL28B rs8099917 non-TT genotypes, those with rs10846744 non-GG genotype had a higher SVR rate than those with GG genotypes. In addition, patients with GG genotype had a higher fasting blood glucose level than those with CC genotype. In conclusion, SCARB1 gene polymorphisms may serve as a potential predictor of treatment responses in CHC patients receiving interferon-based therapy. (ClinicalTrials.gov number, NCT02714712).

    Background Pharmacologic treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia often includes alpha-blockers and 5-alpha reductase inhibitors. Many clinicians use alpha-blockers for rapid symptom control, later adding 5-alpha reductase inhibitors to modify long-term disease progression. Delaying the addition of these medications has been shown to result in reduced clinical outcomes. The economic impact of this practice has not been widely studied or reported to date. Objective The objective of this study was to assess the economic impact of delaying initiation of concomitant 5-alpha reductase inhibitor therapy (≥30 days) in patients receiving alpha-blockers for lower urinary tract symptoms. Methods Using 2 nationally representative databases (Integrated Health Care Information Solutions and PharMetrics), 2 retrospective analyses were conducted involving 2636 and 4260 men, respectively, aged ≥50 years treated for benign prostatic hyperplasia between 2000 and 2007. Economic outcomes (ie, the cost of therapy and the use of healthcare resources) were compared for adding 5-alpha reductase inhibitor therapy early (within <30 days of initiating an alpha-blocker) versus delaying these medications (≥30 days after initiating an alpha-blocker). Results In the Integrated Health Care Information Solutions analysis, patients in the early add-on therapy group (n = 1572) had lower benign prostatic hyperplasia–related medical costs in the posttreatment period than those in the delayed-therapy group (n = 1064), $349 versus $618 (P <.0001). Similar trends were seen in the PharMetrics analysis—the medical costs in the early add-on therapy group (n = 2604) and delayed group (n = 1656) were $344 versus $449, respectively (P <.001). Pharmacy costs were $1068 for the early-treatment cohort and $989 for the delayed-treatment cohort for the Integrated Health Care Information Solutions database, yielding total costs of $1417 and $1606, respectively

    Purpose: We have previously reported that continuous hepatic arterial infusion chemotherapy (HAIC) might be more effective for advanced hepatocellular carcinoma (aHCC) in patients with liver cirrhosis (LC) related to HCV infection (C-LC) or alcohol abuse (A-LC) than in patients who had LC related to HBV infection (B-LC). The aim of the present study was to retrospectively assess the efficacy of lamivudine therapy for B-LC patients with aHCC undergoing HAIC. Methods: Seventeen adult Japanese B-LC patients with aHCC were treated by HAIC with or without lamivudine (100 mg/day) between 2002 and 2008 at our hospital. Their tumors were inoperable according to computed tomography findings. HAIC (LV at 12 mg/hr, CDDP at 10 mg/hr, and 5-FU at 250 mg/22 hr) was given via the proper hepatic artery every 5 days for 4 weeks using a catheter connected to a subcutaneously implanted drug delivery system. Results: Nine of the 17 patients received lamivudine at a dose of 100 mg/day together with HAIC (LAM group), while 8 patients did not receive lamivudine and only had HAIC (non-LAM group). The response rate was 12.5 in the non-LAM group and 0.0% in the LAM group. However, the survival of the LAM group was better than that of the non-LAM group, although there was no significant difference between them. The median survival time of the LAM and non-LAM groups was 310 and 157 days, respectively. HBV-DNA levels were significantly lower after chemotherapy compared with that before chemotherapy in the LAM group. In the non-LAM group, the percentage of Th2 cells before HAIC and after HAIC was significantly higher than in the control group. However, the percentage of Th2 cells in the LAM group after HAIC was not different from that in the control group, although it was significantly higher in the LAM group than in the control group before chemotherapy. Conclusions: These results indicate that lamivudine therapy may prolong the survival of B-LC patients receiving HAIC for aHCC by reducing HBV

    The aim of this work is to describe the outcome of a series of patients with hepatitis C virus (HCV)-related vasculitis who were treated with corticosteroids and I.V. cyclophosphamide without receiving any antiviral therapy. The data of 16 patients with HCV infection and vasculitis were retrospectively analyzed for the treatment outcome in the present study. Eleven patients were females (68.8%) with a mean age of 49.6 ± 10.0 years. Nine patients (56.2%) had medium-sized vessel vasculitis (group A) and seven patients (43.8%) had small vessel vasculitis (group B). Disease activity was assessed using the Birmingham Vasculitis Activity Score (BVAS 2003) and organ damage was assessed by the Vasculitis Damage Index (VDI). HCV infection was confirmed in all patients by the detection of antibodies to HCV in serum by ELISA and HCV RNA using qualitative PCR. Quantitative PCR was done using the branched DNA technique. None of our study patients had received antiviral therapy, but they all received I.V.-pulsed cyclophosphamide monthly for 6 months, then every 3 months for six times if needed, preceded by I.V. methylprednisolone. Twelve patients (75%) had undetectable viral load by the quantitative technique. The drop in mean BVAS recorded at different intervals was highly significant. Although there was a drop in the VDI mean between the first and second reading, it was not statistically significant. All patients responded to treatment. Seven patients (43.8%) had relapse. Two patients died (12.5%). One patient died from renal failure (group B) and another died from sepsis (group A). The treatment outcomes were not statistically significant between the two vasculitis groups. A subset of patients with HCV-related vasculitis and with low levels of viremia can be safely treated with corticosteroids and cyclophosphamide alone. Despite successful treatment, a significant proportion of patients relapse and some develop severe complications and death. PMID:20924628

    Although there are lots of studies about the risk for the hepatitis B virus infection such as the residual risk for donated blood, there is no research on the risk of HBV infection, from the viewpoint of recipients in Korea. Using the data about HBsAg status of donated blood in 2008 and 2009, the distribution of blood components from the claim data of health insurance in 2009, the distribution of HBsAg and HBsAb of recipients, and some assumptions, we quantified the number of recipients in Korea that might be expected to receive HBV-contaminated blood components, as a proxy index for HBV infection by transfusion in 2009. Of the 376,211 recipients, the number who might be expected to receive blood components with HBV in 2009 was 23.2 (95 % CI 13.6, 36.8) in the basic model, 43.2 (95 % CI 25.4, 68.7) in extended model I, 55.2 (95 % CI 32.5, 87.7) in extended model II and 101.6 (95 % CI 59.8, 161.4) in extended model III. The number of HBV-positive samples per 100,000 transfused units was 0.6 in the basic model (95 % CI 0.3, 0.9), 1.1 in extended model I (95 % CI 0.6, 1.8), 1.4 in extended model II (95 % CI 0.8, 2.2), and 2.6 in extended model III (95 % CI 1.5, 4.1). This study showed that a few recipients might receive HBV-contaminated blood component by transfusion. These results could be used as a scientific evidence for health policy on HBV transfusion infection. PMID:27429524

    Objectives To identify risk factors for hepatitis C among HIV-positive men who have sex with men (MSM), focusing on potential sexual, nosocomial, and other non-sexual determinants. Background Outbreaks of hepatitis C virus (HCV) infections among HIV-positive MSM have been reported by clinicians in post-industrialized countries since 2000. The sexual acquisition of HCV by gay men who are HIV positive is not, however, fully understood. Methods Between 2006 and 2008, a case-control study was embedded into a behavioural survey of MSM in Germany. Cases were HIV-positive and acutely HCV-co-infected, with no history of injection drug use. HIV-positive MSM without known HCV infection, matched for age group, served as controls. The HCV-serostatus of controls was assessed by serological testing of dried blood specimens. Univariable and multivariable regression analyses were used to identify factors independently associated with HCV-co-infection. Results 34 cases and 67 controls were included. Sex-associated rectal bleeding, receptive fisting and snorting cocaine/amphetamines, combined with group sex, were independently associated with case status. Among cases, surgical interventions overlapped with sex-associated rectal bleeding. Conclusions Sexual practices leading to rectal bleeding, and snorting drugs in settings of increased HCV-prevalence are risk factors for acute hepatitis C. We suggest that sharing snorting equipment as well as sharing sexual partners might be modes of sexual transmission. Condoms and gloves may not provide adequate protection if they are contaminated with blood. Public health interventions for HIV-positive gay men should address the role of blood in sexual risk behaviour. Further research is needed into the interplay of proctosurgery and sex-associated rectal bleeding. PMID:21408083

    Amongst people on opioid maintenance treatment (OMT), chronic hepatitis C (HCV) is common but infrequently treated. Numerous barriers, including misuse of alcohol may limit efforts at anti-viral treatment. The aim of this study was to define barriers, including alcohol misuse, to the effective treatment of HCV amongst OMT recipients. Ninety-four OMT patients completed the 3-item Alcohol Use Disorders Identification Test (AUDIT-C). A semi-structured interview was used in 53 subjects to assess alcohol use in detail, psychological health, discrimination and access to HCV treatment. Feasibility of brief intervention for alcohol misuse was assessed. Of the screening participants, 73% reported they were HCV positive. Of the detailed interview participants, 26% reported no drinking in the past month, but 53% scored 8 or more on AUDIT and 42% exceeded NHMRC drinking guidelines. Twenty subjects received brief intervention and among 17 re-interviewed at one month, alcohol consumption fell by 3.1 g/day (p = 0.003). Severe or extremely severe depression, stress and anxiety were found in 57%, 51% and 40% of interviewees respectively. Episodic heavy drinking, mental health problems, perceived discrimination, limited knowledge concerning HCV were all common and uptake of HCV treatment was poor. Brief intervention for alcohol use problems was acceptable to OMT patients, and warrants further study. PMID:17454012

    Work productivity is impacted in hepatitis C virus (HCV)-infected patients and has been linked to treatment. In two Phase 3 trials, ADVANCE and ILLUMINATE, treatment-naïve genotype 1 chronic HCV-infected patients received 12-week telaprevir (T) with 24 (T12PR24)- or 48 (T12PR48)-week peginterferon alfa-2a/ribavirin. The objective of this analysis was to examine the impact of chronic HCV infection and its treatment with combination therapy on work productivity. The 5-item, self-reported work productivity questionnaire (WPQ) was administered in Phase 3 trials to assess unemployment status, days unable to work due to HCV/treatment, reduced hours worked and impact on productivity in prior 4 weeks. Descriptive statistics and multivariate regression analyses were employed in analyses of pooled trial data. About 1147 patients were included; 22% (n = 255) were unemployed at baseline, with 8% being unemployed due to health reasons. At week 12, there were no differences by treatment regimen in the number of days unable to work. At week 48, improvements were observed earlier among patients receiving the shorter duration of T combination treatment. Mean (95% CI) change from baseline in days unable to work was -0.48 (-0.85, -0.11) days for T12PR24, 1.43 (0.63, 2.24) days for T12PR48 and 1.24 (0.18, 2.30) days for PR48 with placebo. Predictors of days unable to work were identified and include demographic characteristics, pretreatment and on-treatment levels of fatigue, as well regional variation. In post hoc analyses of the ADVANCE and ILLUMINATE trials, work productivity decreased during the initial 12 weeks regardless of treatment group. PMID:24528927

    The present pilot study investigated the implementation feasibility, and efficacy for reducing alcohol and drug craving, of a brief, 3-session heart rate variability biofeedback (HRV BFB) intervention added to a traditional 28-day substance abuse disorder (SUD) inpatient treatment program. Forty-eight young adult men received either treatment as usual (TAU) plus three sessions of HRV BFB training over three weeks, or TAU only. Participants receiving HRV BFB training were instructed to practice daily using a handheld HRV BFB device. HRV BFB training was well tolerated by participants and supported by treatment staff. Men receiving TAU + HRV BFB demonstrated a greater, medium effect size reduction in alcohol and drug craving compared to those receiving TAU only, although this difference did not reach statistical significance. In addition, an interaction effect was observed in analyses that accounted for baseline craving levels, wherein heart rate variability (HRV) levels at treatment entry were predictive of changes in craving in the TAU group only. Low baseline levels of HRV were associated with increases in craving, whereas higher baseline HRV levels were associated with greater decreases in craving from start to end of treatment. In the TAU + HRV BFB group, however, there was no such association. That is, HRV BFB appeared to dissociate individual differences in baseline HRV levels from changes in craving. Given that alcohol and drug craving often precipitates relapse, HRV BFB merits further study as an adjunct treatment to ameliorate craving experienced by persons with substance use disorders.

    Background: Nonalcoholic fatty liver disease (NAFLD) has different prevalence rates in various parts of the world and is a risk factor for diabetes and cardiovascular disease that could progress to nonalcoholic steatohepatitis, cirrhosis, and liver failure. Objectives: The current study aimed to investigate the effect of Aerobic Training (AT) and resistance training (RT) on hepatic fat content and liver enzyme levels in Iranian men. Patients and Methods: In a randomized clinical trial study, 30 men with clinically defined NAFLD were allocated into three groups (aerobic, resistance and control). An aerobic group program consisted of 45 minutes of aerobic exercise at 60% - 75% maximum heart rate intensity, a resistance group performed seven resistance exercises at intensity of 50% - 70% of 1 repetition maximum (1RM ) and the control group had no exercise training program during the study. Before and after training, anthropometry, insulin sensitivity, liver enzymes and hepatic fat were elevated. Results: After training, hepatic fat content was markedly reduced, to a similar extent, in both the aerobic and resistance exercise training groups (P ≤ 0.05). In the two exercise training groups, alanine amino transferase and aspartate amino transferase serum levels were significantly decreased compared to the control group (P = 0.002) and (P = 0.02), respectively. Moreover, body fat (%), fat mass (kg), homeostasis model assessment insulin resistance (HOMI-IR) were all improved in the AT and RT. These changes in the AT group were independent of weight loss. Conclusions: This study demonstrated that RT and AT are equally effective in reducing hepatic fat content and liver enzyme levels among patients with NAFLD. However, aerobic exercise specifically improves NAFLD independent of any change in body weight. PMID:26587039

    Objective To evaluate the appropriateness of follow-up with only non-enhanced CT (NECT) in patients with gastrointestinal cancer. Subjects and Methods This retrospective study included 323 patients with colorectal and gastric cancer who underwent two consecutive CT examinations (CT1 and CT2), including non-contrast and portal venous phase CT images, with an interval of 1 year. Patients were divided into 2 groups: Group A included patients with no hepatic metastasis on CT1 and with or without newly developed metastasis on CT2 to evaluate the diagnostic performance of NECT for detecting newly developed hepatic metastasis; Group B included patients with known hepatic metastasis both on CT1 and CT2 to evaluate the accuracy of NECT for the assessment of hepatic metastasis based on RECIST criteria (version 1.1). Contrast-enhanced CT (CECT) images were considered as reference standards. Results Group A included 172 patients (M:F = 107:65; mean age, 62.6 years). Among them, 57 patients had 95 metastases (mean size, 2.2 ± 1.3 cm). Per patient and per lesion sensitivity for diagnosing newly developed hepatic metastasis was 56.1–66.7% and 52.6–56.8%, respectively. In terms of small metastases (<1.5 cm), per lesion sensitivity was significantly decreased to 28.1–34.4% (P < 0.05). Metastasis size measurements were significantly smaller on NECT (P < 0.001) compared with reference standards. In Group B, the accuracy of response evaluation based on RECIST criteria was 65.6–72.2%. Conclusions NECT showed inadequate diagnostic performances in both detecting newly developed hepatic metastasis and evaluating the response of hepatic metastasis based on RECIST criteria.

    We summarize the clinical history and laboratory results following the introduction of tenofovir among 6 patients coinfected with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) who presented with severe liver disease while receiving lamivudine-based highly active antiretroviral therapy. In all cases, the introduction of tenofovir led to a sustained undetectable HBV and HIV loads, with marked clinical and laboratory improvement in liver function. We provide supporting evidence for the role of tenofovir in the management of advanced HBV infection in HIV-positive patients after the development of lamivudine resistance. PMID:18181733

    Background: The PrePex medical male circumcision (MMC) device has been approved for MMC scale-up. However, the WHO has recommended that a country-specific situation analysis should be carried out before MMC device rollout. Method: A cross-sectional survey was conducted over 12 months in 3 MMC clinics, by trained nurses and researchers, to ascertain attitudes toward PrePex MMC in 3 groups: men consenting for PrePex MMC (PrePex recipients), people accompanying men, and adolescents coming for either PrePex or surgical circumcision (MMC escorts) and men refusing the PrePex device MMC (PrePex rejecters). All participants received information on surgical and the PrePex device MMC methods. Results: A total of 312 PrePex recipients, 117 MMC escorts, and 21 PrePex rejecters were recruited into the study. Ninety-nine percent of PrePex recipients thought that their expectations (safe, convenient, minimal pain) were met, and they were pleased with cosmetic outcome. Fifty-nine percent of PrePex rejecters opted for surgical circumcision because they perceived PrePex to be novel and risky. All 3 groups of participants were concerned about odor, dead skin, discomfort, healing time, and wound care. Ninety-eight percent of MMC escorts, 99% of PrePex recipient, and 81% of PrePex rejecters perceived PrePex circumcision as an acceptable option for South African MMC programmes. Conclusions: This acceptability study suggests that PrePex MMC is considered safe and convenient and could be incorporated into existing MMC programmes. Concerns about odor, pain, wound care, and healing time suggest that the need for more research to further optimize methods and that MMC clients should be counseled on available methods to enable them to choose among options based on their preferences.

    Objectives Men who have sex with men (MSM) are at higher risk for coinfection with hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis than the general population. HIV infection and these coinfections accelerate disease progression reciprocally. This study evaluated the prevalence and incidence of these coinfections in HIV1-positive MSM in Germany. Materials and Methods As part of a nationwide, multicenter, prospective cohort study of HIV-infected MSM, plasma samples collected yearly were screened for HBsAg and antibodies to HBc, HBs, HCV, and syphilis. Samples with indications of active HBV or HCV infection were confirmed by polymerase chain reaction. Prevalence and incidence of each infection and incidence rates per study participant were calculated, and incidences over 4-year time intervals compared. Results This study screened 5,445 samples from 1,843 MSM. Median age at HIV seroconversion was 33 years. Prevalences of active, cleared, and occult HBV, and of active/cleared HCV were 1.7%, 27.1%, 0.2%, and 8.2%, respectively, and 47.5% had been effectively vaccinated against HBV. Prevalence of antibodies to Treponema pallidum and of triple or quadruple sexually transmitted infections (STIs) were 39.6% and 18.9%, respectively. Prevalence of STI, cleared HBV, HBV vaccination, and history of syphilis differed significantly among age groups. Incidences of HBV, HCV, and syphilis were 2.51, 1.54, and 4.06 per 100 person-years, respectively. Incidences of HCV and syphilis increased over time. HCV incidence was significantly higher in MSM coinfected with syphilis and living in Berlin, and syphilis incidence was significantly higher for MSM living in Berlin. Discussion Despite extensive HBV vaccination campaigns, fewer than 50% of screened MSM were effectively vaccinated, with a high proportion of HIV-positive MSM coinfected with HBV. High rates of STI coinfections in HIV-positive MSM and increasing incidences emphasize the need for better tailored campaigns for

    Inosine triphosphatase (ITPA) single nucleotide polymorphisms (SNPs) are strongly associated with protection against ribavirin (RBV)-induced anaemia in European, American and Asian patients; however, there is a paucity of data for Brazilian patients. The aim of this study was to evaluate the ITPA SNP (rs7270101/rs1127354) frequency in healthy and hepatitis C virus (HCV)-infected patients from Brazil and the association with the development of severe anaemia during antiviral therapy. ITPA SNPs were determined in 200 HCV infected patients and 100 healthy individuals by sequencing. Biochemical parameters and haemoglobin (Hb) levels were analysed in 97 patients who underwent antiviral therapy. A combination of AArs7270101+CCrs1127354 (100% ITPase activity) was observed in 236/300 individuals. Anaemia was observed in 87.5% and 86.2% of treated patients with AA (rs7270101) and CC genotypes (rs1127354), respectively. Men with AA (rs7270101) showed a considerable reduction in Hb at week 12 compared to those with AC/CC (p = 0.1475). In women, there was no influence of genotype (p = 0.5295). For rs1127354, men with the CC genotype also showed a sudden reduction in Hb compared to those with AC. Allelic distribution of rs7270101 and rs1127354 shows high rates of the genotypes AA and CC, respectively, suggesting that the study population had a great propensity for developing RBV-induced anaemia. A progressive Hb reduction during treatment was observed; however, this reduction was greater in men at week 12 than in women. PMID:26154744

    Injection drug use accounts for the majority of incident and prevalent cases of hepatitis C virus (HCV) infection. However, very few injection drug users (IDUs) have received treatment for this condition given issues of medical or psychiatric co-morbidity, ongoing substance abuse and a widely held belief that such individuals will not be able to adhere to the requirements of therapy, including regular medical follow-up. With this in mind, we sought to evaluate HCV treatment uptake and outcomes among current and former IDUs attending a weekly peer support group and receiving directly observed HCV therapy. Utilizing the existing infrastructure for the management of addictive disease, we have developed a model of "one-stop shopping" whereby the treatment of addiction, HCV and other medical conditions are fully integrated, with the collaboration of nurses, counsellors, addiction specialists, infectious disease specialists, primary care physicians and researchers. Subjects interested in receiving treatment for HCV infection were referred to a weekly peer-support group and evaluated for treatment. Patients received therapy with pegylated interferon-alpha2a or -alpha2b, both in combination with ribavirin. All injections were directly observed. Overall, we observed a high uptake of HCV treatment among attendees, with 51 percent either receiving or about to receive therapy. To date, 18 patients have initiated treatment for HCV infection and 12 have completed therapy. Overall, 8/12 (67 percent) subjects achieved an end of treatment response (genotype 1, 67 percent; genotypes 2/3, 67 percent), despite ongoing drug use in 75 percent of patients during treatment. These data demonstrate that with the appropriate programs in place, a high uptake of HCV treatment can be achieved among IDUs referred to a peer-support group. Moreover, the treatment of HCV in current and former IDUs within a multidisciplinary DOT program can be successfully undertaken, resulting in ETRs similar to

    We aimed at evaluating the risk of liver cancer in different levels of HBsAg among Chinese men and women. We carried out a nested case-control study including 363 cases and 3,511 controls in two population-based cohorts in Shanghai. Plasma samples collected at enrollment were quantified for HBsAg levels using the Architect QT assay. Conditional logistic regression was performed to estimate the odds ratios (ORs) and 95% confidence intervals (95%CIs) for liver cancer, with adjustment for potential confounders. HBsAg was detected in 6.29% of control subjects overall (7.02% in men and 4.98% in women). HBsAg levels were positively associated with liver cancer risk in a dose-response manner (Ptrend<0.001). Such association showed a significant gender disparity. With increasing levels of HBsAg, liver cancer risks rose more steeply in men than in women. In men, the adjusted ORs increased from 7.27 (95%CI: 3.49–15.15) at the lowest detectable level of HBsAg (5–9 IU/ml) to 7.16 (95%CI: 3.21–15.96), 34.30 (95%CI: 16.94–69.44), and 47.33 (95%CI: 23.50–95.34) at the highest level of HBsAg (≥1,000 IU/ml) compared to those negative for HBsAg. The corresponding ORs were much lower for women, from 1.37 (95%CI: 0.25–7.47) to 3.81 (95%CI: 1.09–13.28), 7.36 (95%CI: 2.41–22.46), and 16.86 (95%CI: 7.24–39.27), respectively. HBsAg quantification has potential to distinguish individuals at different risks of liver cancer. Men with the lowest detectable level of HBsAg should still pay attention to their liver cancer risks, but those with a higher level may be given a higher priority in future liver cancer surveillance program.

    Background. We report on the hepatitis C virus (HCV) epidemic among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) in the United Kingdom and model its trajectory with or without scaled-up HCV direct-acting antivirals (DAAs). Methods. A dynamic HCV transmission model among HIV–diagnosed MSM in the United Kingdom was calibrated to HCV prevalence (antibody [Ab] or RNA positive), incidence, and treatment from 2004 to 2011 among HIV-diagnosed MSM in the UK Collaborative HIV Cohort (UK CHIC). The epidemic was projected with current or scaled-up HCV treatment, with or without a 20% behavioral risk reduction. Results. HCV prevalence among HIV-positive MSM in UK CHIC increased from 7.3% in 2004 to 9.9% in 2011, whereas primary incidence was flat (1.02–1.38 per 100 person-years). Over the next decade, modeling suggests 94% of infections are attributable to high-risk individuals, comprising 7% of the population. Without treatment, HCV chronic prevalence could have been 38% higher in 2015 (11.9% vs 8.6%). With current treatment and sustained virological response rates (status quo), chronic prevalence is likely to increase to 11% by 2025, but stabilize with DAA introduction in 2015. With DAA scale-up to 80% within 1 year of diagnosis (regardless of disease stage), and 20% per year thereafter, chronic prevalence could decline by 71% (to 3.2%) compared to status quo in 2025. With additional behavioral interventions, chronic prevalence could decline further to <2.5% by 2025. Conclusions. Epidemiological data and modeling suggest a continuing HCV epidemic among HIV-diagnosed MSM in the United Kingdom driven by high-risk individuals, despite high treatment rates. Substantial reductions in HCV transmission could be achieved through scale-up of DAAs and moderately effective behavioral interventions. PMID:26908813

    Background Men who have sex with men (MSM) are at increased risk of exposure to hepatitis B virus (HBV) compared with the general population. This study aims to assess the epidemiological and virological characteristics of HBV infection in a sample of MSM in Brazil, where data are scarce. Methods A cross-sectional study was conducted among MSM in the City of Goiânia, Central Brazil, from March to November 2014, using Respondent-Driven Sampling (RDS). After signing the consent form, participants were interviewed and a blood sample collected. All samples were tested for HBV serological markers and HBV DNA. HBV nucleotide sequence analysis was also performed. Results A total of 522 MSM were recruited in the study. The prevalence of HBV infection (current or past [presence of anti-HBc marker]) was 15.4% (95% CI: 8.7–25.8) and the rate of HBsAg carriers was 0.6% (95% CI: 0.2–1.6). About 40% (95% CI: 32.3–48.8) of the participants had serological evidence of previous HBV vaccination (reactive for isolated anti-HBs). In addition, 44.3% (95% CI: 36.1–52.9) were seronegative for all HBV markers. Age over 25 years old, receptive anal intercourse, previous sex with women, and history of sexually transmitted infections (STIs) were factors associated with HBV infection. HBV DNA was detected only in HBsAg-positive individuals. HBV isolates were classified into genotype A (subgenotypes A1 and A2), and some mutations were identified throughout the genome. Therefore, occult HBV infection was not observed in the study population. Conclusions Public health strategies should be improved for the MSM population in order to prevent HBV and other STIs, as well as to provide appropriate management of patients with active infections.

    Hepatitis B virus (HBV) reactivation is an increasingly recognized cause of morbidity and mortality in patients undergoing chemotherapy. In haematology, the risk of reactivation of B hepatitis among HBsAg-positive patients has been documented; therefore, use of lamivudine prophylaxis is recommended before starting chemotherapy. Differently, for HBsAg-negative patients with markers of previous HBV infection (i.e., presence of isolated anti-HBc positivity) (anticore patients) management strategies are not univocal. We describe a rare case of HBV reactivation in an anticore patient after fludarabine therapy for chronic lymphocytic leukaemia. The patient fully recovered after a 6-month course of lamivudine with persistent HBV-DNA clearance and loss of HBsAg. The most important feature of this case is that fludarabine alone infrequently determines HBV reactivation, especially in anticore patients. Therefore, we suggest that patients candidates to receive fludarabine therapy should be considered for lamivudine prophylaxis, not only if HBsAg-positive, but even if anticore-positive only.

    Adefovir dipivoxil (ADV) is effective for hepatitis B virus (HBV) infection; however, ADV may provoke renal injury resulting in osteomalacia, and this side effect is seldom recognized until bone fractures emerge. We herein present a 66-year-old woman with HBV infection who received ADV for 6 years. Although she exhibited no sign of bone fractures, her urinary β-2 microglobulin (β2MG) level increased to 83,837 μg/L and scintigraphy revealed minimal fractures of the third rib. ADV was subsequently reduced and her urinary β2MG rapidly fell to 3,637 μg/L. Conversely, her urinary N-acetyl-β-D-glucosaminidase, and serum phosphate, alkaline phosphatase levels did not respond.

    OBJECTIVE: To determine the prevalence and risk factors for hepatitis C virus (HCV) infection in a cohort of homosexually active men, with particular reference to assessing sexual transmission. DESIGN: Prevalence based on cross-sectional testing for HCV (c100 protein) antibody in a cohort using sera stored between 1984 and 1989, and assessment of risk factors using a case-control analysis based on questionnaire data from HCV positive and negative subjects. SUBJECTS/SETTING: 1038 homosexually active men who were participating in a prospective study established to identify risk factors for AIDS. They had been recruited through private and public primary care and sexually transmissible disease (STD) services in central Sydney. MAIN OUTCOME MEASURES: Prevalence of HCV antibody and its association with human immunodeficiency virus type 1 (HIV-1) infection and other STDs, number of sexual partners, sexual practices and recreational drug use. RESULTS: Overall, 7.6% of subjects tested were seropositive for HCV antibody. In univariate analysis, HCV infection was significantly associated with injecting drug use (IDU) (OR = 8.18, p < 0.0001) and HIV infection (OR = 3.14, p < 0.0001) and with self reported history of syphilis (OR = 1.88, p = 0.016), anogenital herpes (OR = 1.93, p = 0.017), gonorrhoea (OR = 2.43, p = 0.009) and hepatitis B (OR = 1.92, p = 0.010). In case control analysis, similar sexual behaviours (partner numbers and practices) were reported by HCV positive and HCV negative subjects except that HCV negative subjects more frequently reported engaging than HCV positive subject in unprotected receptive anal intercourse without ejaculation (OR = 0.61, p = 0.034), unprotected insertive (OR = 0.59, p = 0.039) and receptive (OR = 0.56, p = 0.016) oro-anal intercourse (rimming) and insertive fisting (OR = 0.48, p = 0.034).

    Liver stiffness (LS) assessed using transient elastography (TE) can assess the risk of developing hepatocellular carcinoma (HCC). We evaluated whether TE, when compared with histological data as a reference standard, can predict the risk of HCC development in chronic hepatitis B (CHB) patients starting antiviral therapy.Observational cohort database of 381 patients with CHB who underwent liver biopsy (LB) and TE were reviewed. All patients underwent surveillance for HCC development using ultrasonography and alpha-fetoprotein.During the median follow-up period of 48.1 (interquartile range 30.3-69.3) months, HCC developed in 34 (8.9%) patients. In patients with HCC development, age, proportion of diabetes mellitus, histological fibrosis stage, and LS value were significantly higher than those in patients without (all P <0.05). The cumulative incidence rates of HCC increased significantly in association with elevated LS value in 3 stratified groups (LS value <8, 8-13, and >13 kPa; log-rank test, P <0.001), and with higher histological fibrosis stage in 3 stratified groups (F0-2, F3, and F4; log-rank test, P <0.001). On multivariate analysis, along with age, LS value was an independent predictor of HCC development (hazard ratio 1.041, P <0.001), whereas histological staging was not (P >0.05).TE predicted HCC development independently in patients with CHB starting antiviral therapy. However, further investigation is needed to determine whether the current surveillance strategy can be optimized based on the LS value at the time of starting antiviral therapy. PMID:27015173

    Treatment of Hepatitis C virus (HCV) with pegylated interferon and ribavirin (IFN/RBV) can be associated with neuropsychiatric side effects, which may necessitate dose reductions or treatment discontinuation. This study aimed to characterize the time course and predictors of cognitive and affective/mood symptoms after IFN/RBV treatment initiation. Forty individuals enrolled in a longitudinal project underwent comprehensive cognitive, medical, and psychiatric assessment at baseline and 10 weeks, 6 months, 12 months, and 18 months after treatment initiation. Analyses were conducted to determine the prevalence of neurocognitive impairment over time, explicate the relationship between neurocognitive impairment, neuropsychiatric symptoms, and liver disease at each time point, and identify predictors of neurocognitive decline as well as cognitive effects of viral clearance. By 10 weeks after initiating IFN/RBV, the prevalence of neurocognitive impairment rose from 22.5% to 47.4% (p < 0.05). Infection with Genotype 1 and premorbid depression were associated with more severe declines (p < 0.05). After 18 months, 42.5% remained neurocognitively impaired, independent of viral clearance, severity of liver disease, and current depressive symptoms. Undetectable viral load was not associated with improvement 18 months after initiating treatment (p > .10). Results of the current study indicate that IFN/RBV treatment-emergent neurocognitive declines are significant, prevalent, and may persist long after treatment cessation. Clinicians should monitor cognition throughout the course of treatment for HCV, noting that early declines may indicate individuals at elevated risk for persistent neurocognitive impairment. Longer-term studies are needed to determine whether lasting declines may remit over longer intervals. PMID:25326107

    OBJECTIVE: The purpose of this study was to determine the effect of propranolol on peripheral lipolysis in massively burned children during treatment with recombinant human growth hormone (rhGH), and to ascertain whether decreased free fatty acid availability for re-esterification would alter the hepatic rate of secretion of triglycerides (TGs) bound to very low density lipoproteins (VLDLs). BACKGROUND: Fatty liver occurs in severely burned patients, often resulting in a twofold increase in liver size. This could be the result of an imbalance between increased provision of free fatty acids from peripheral lipolysis, coupled with no increase in fat oxidation, and insufficient rate of secretion of TGs from the liver. METHODS: In a cross-over study, six burned children were treated with either rhGH or rhGH plus propranolol. On the sixth day of treatment, isotopic tracer infusions were conducted to determine the rate of release of free fatty acid (Ra FFA) from peripheral tissue and the rate of secretion of VLDL-bound TGs by the liver. RESULTS: Exogenous rhGH increased Ra FFA in children with large third-degree burns. Propranolol decreased Ra FFA, but the rate of secretion of fatty acids in the form of VLDL-TG from the liver was maintained. Plasma FFA, as opposed to fatty acids newly synthesized in the liver, were the primary precursors for hepatic triglyceride synthesis. CONCLUSIONS: The administration of propranolol to burned children receiving rhGH is safe, has salutary cardiovascular effects, decreases the release of FFA from adipose tissue and increases the efficiency of the liver in secreting fatty acids as VLDL TGs.

    Background and Aims Individualization of treatment with peginterferon alfa and ribavirin in patients with chronic hepatitis C showed benefit in controlled trials and was implemented in treatment guidelines to increase response rates and to reduce side effects and costs. However, it is unknown whether individualization was adopted in routine daily practice and whether it translated into improved outcomes. Methods From a large noninterventional cohort study, clinical and virologic response data of 10,262 HCV patients who received peginterferon alfa-2a and ribavirin between 2003-2007 and 2008-2011 were analyzed. To account for treatment individualization, a matched-pair analysis (2,997 matched pairs) was performed. Variation in treatment duration and dosing of ribavirin were analyzed as indicators for individualization. Results Sustained virological response (SVR) rates were similar between 2003-2007 and 2008-2011 (62.0% vs. 63.7%). Patients with comorbidities were more abundant in the later period, (44.3% vs. 57.1%). The subsequent matched-pair analysis demonstrated higher SVR rates in the 2008-2011 period (64.3%) than in the 2003-2007 period (61.2%, p=0.008). More patients received abbreviated or extended treatment regimens in the later than the earlier period as an indicator of treatment individualization. To the same end, ribavirin doses were higher in the later period (12.6 versus 11.6 mg/kg/day). Factors independently associated with SVR included HCV genotype, low baseline viral load, younger age, route of infection, absence of concomitant diseases, lower APRI score, normal gamma-GT, higher ribavirin doses, no substitution for drug abuse, treatment duration, and treatment in the 2008-2011 period. Conclusions Treatment individualization with peginterferon alfa and ribavirin was implemented in daily routine between 2003-2007 and 2008-2011, SVR rates improved in the same period. These findings may be most relevant in resource-limited settings. PMID:26230998

    Efficacy, safety, and economical aspects of treatment with abacavir, zidovudine, stavudine, and phosphazide in the schemes of antiretroviral therapy of the HIV-infected patients receiving therapy for hepatitis C virus were tested. Clinical, immunological, and virologic efficacy of treatment and dynamics of hemoglobin, thrombocytes, and alanine aminotransferase as markers of common adverse events recorded at the start of the antiviral therapy of chronic hepatitis C and after 4, 8, 12, 24, 48 weeks of the treatment were evaluated. The usage of these drugs in the schemes of antiretroviral therapy exhibited efficacy, high tolerability and safety for all HIV reverse transcriptase inhibitors. PMID:27145599

    Currently, limited data are available regarding the efficacy and safety of pegylated interferon alpha-2a (PEG-IFN α-2a) in Korean patients with chronic hepatitis B (CHB), in whom hepatitis B virus (HBV) genotype C is the most common type.We collected data from 439 patients (HBeAg positive, n = 349; HBeAg negative, n = 90) with CHB who were treated with PEG-IFN α-2a as a first-line therapy from 18 institutions. Treatment responses at the end of treatment (ET) and at 6 months posttreatment (PT6) were compared between the patients who were treated for 24 weeks versus 48 weeks, and adverse events (AEs) were evaluated.In HBeAg-positive patients, those who received PEG-IFN α-2a for 48 weeks showed significantly higher HBV DNA suppression (HBV DNA < 2000 IU/mL) than those who were treated for 24 weeks (48 weeks vs 24 weeks; at ET, 44.4% vs 36.7%, P = 0.035; at PT6, 35.9% vs 13.3%, P = 0.035). The HBeAg seroconversion rate at ET was 18.1% in 48-week treatment group, which is significantly higher than the 2.2% (P < 0.001) that was seen in 24-week treatment group. This finding also continued at PT6 (29.0% vs 10.0%, P < 0.001). Following 48 weeks of treatment in HBeAg-negative patients, HBV DNA suppression at ET was higher than in HBeAg-positive patients (87.8% vs 44.4%). AEs were typical of those associated with PEG-IFN α-2a.In naïve Korean HBeAg-positive CHB patients treated with PEG-IFN α-2a, higher rates of HBV DNA suppression and HBeAg seroconversion were achieved in the 48-week treatment group than in the 24-week treatment group without additional risk of AEs.

    This paper presents data from two studies that evaluated 5-y and 10-y persistence of antibodies against hepatitis B (HBV) surface antigen (anti-HBs) and immune response to an HBV vaccine challenge in children and adolescents who had received three doses of a HBV vaccine in infancy as part of routine clinical practice [NCT00519649/NCT00984139]. Anti-HBs antibody concentrations ≥ 10 mIU/ml persisted in 83.3% (95% confidence interval [CI]: 78.5–87.5) and 78.3% (95% CI: 73.1–83.0) of subjects aged 7–8 y and 12–13 y, respectively 5–10 y after infant vaccination. One month postchallenge dose, 98.2% (95% CI: 95.9–99.4) and 93.7% (95% CI: 90.2–96.2) of subjects in the two age groups, respectively had anti-HBs antibody concentrations ≥ 100 mIU/ml. Overall, 99.6% (95% CI: 98–100) and 97.2% (95% CI: 94.5–98.8) of subjects aged 7–8 y and 12–13 y mounted an anamnestic response to the HBV challenge dose, which was well-tolerated. Healthy children aged 7–8 y and adolescents aged 12–13 y received three doses of a monovalent pediatric HBV vaccine (10 μg of HBsAg) before 18 mo of age. Serum samples collected before and one month post-HBV vaccine challenge dose were tested for anti-HBs antibody concentrations. Safety assessments were made for the HBV vaccine challenge dose. A three-dose childhood HBV immunization regimen induced persistence of antibodies against HBV infection for 10 y, up to adolescence. This vaccination regimen also conferred long-term immune memory against HBV as evidenced by the strong anamnestic response to the HBV vaccine challenge, despite waning anti-HBs antibody levels.

    Homeless gay and bisexual (G/B) young men have multiple risk factors that increase their risk of contracting hepatitis B virus (HBV) and human immunodeficiency virus (HIV). This study used baseline information from structured instruments to assess correlates of knowledge to HIV and HBV infection from 267 young (18-39 year old) G/B active methamphetamine, cocaine, and crack-using homeless men enrolled in a longitudinal trial. The study is designed to reduce drug use and improve knowledge of hepatitis and HIV/AIDS in a community center in Hollywood, California. Regression modeling revealed that previous hepatitis education delivered to G/B men was associated with higher levels of HIV/AIDS and hepatitis knowledge. Moreover, higher HIV/AIDS knowledge was associated with combining sex and drinking alcohol. Associations with hepatitis B knowledge was found among G/B men who were engaging in sex while under the influence of marijuana, who were receiving support from non-drug users, and who had been homeless in the last 4 months. Although being informed about HIV/AIDS and hepatitis did not preclude risky sexual and drug use behavior, knowledge about the dangers of concurrent sex with substance use is important. As higher levels of knowledge of hepatitis was associated with more moderate drug use, early access to testing and teaching harm reduction strategies remain critical to reduce exposure and infection of HBV and HIV in this population.

    Background. Hepatitis C virus (HCV) infection is a leading cause of liver-related morbidity and mortality in the United States, and injection drug users are at particularly high risk. Methods. This prospective observational cohort study assessed the rate of, and risk factors for, clinical liver disease progression in a cohort of HCV monoinfected and human immunodeficiency virus (HIV)/HCV coinfected drug users using unadjusted and multivariate Cox proportional hazards regression analyses. Results. Of 564 subjects including 421 (75%) with HIV/HCV coinfection and 143 with HCV monoinfection, 55 (10%) had clinical liver disease progression during follow-up with a rate of 25.3 events per 1000 person-years. In unadjusted analysis, there was an interaction between sex and HIV status. In sex-stratified multivariate analysis, HIV/HCV-coinfected women with CD4 <200 cells/mm3 had 9.99 times the risk of liver disease progression as HCV-monoinfected women (confidence interval [CI], 1.84–54.31; P = .008), and white women had a trend towards increased risk of liver disease progression compared with non-white women (hazard ratio, 2.84; CI, .93–8.68; P = .07). Human immunodeficiency virus/HCV-coinfected men with CD4 <200 cells/mm3 had 2.86 times the risk of liver disease progression as HCV-monoinfected men (CI, 1.23-6.65; P = .01). Conclusions. Hepatitis C virus-monoinfected and HIV/HCV-coinfected drug users had high rates of clinical liver disease progression. In those with HIV infection, liver disease progression was associated with advanced immune suppression. This effect was strikingly more pronounced in women than in men. PMID:26955643

    Background Prostate cancer is the most common male cancer in the Western world. The most substantial long term morbidity from this cancer is sexual dysfunction with consequent adverse changes in couple and intimate relationships. Research to date has not identified an effective way to improve sexual and psychosocial adjustment for both men with prostate cancer and their partners. As well, the efficacy and cost effectiveness of peer counselling as opposed to professional models of service delivery has not yet been empirically tested. This paper presents the design of a three arm randomised controlled trial (peer vs. nurse counselling vs. usual care) that will evaluate the efficacy of two couples-based sexuality interventions (ProsCan for Couples: Peer support vs. nurse counselling) on men's and women's sexual and psychosocial adjustment after surgical treatment for localised prostate cancer; in addition to cost-effectiveness. Methods/design Seventy couples per condition (210 couples in total) will be recruited after diagnosis and before treatment through urology private practices and hospital outpatient clinics and randomised to (1) usual care; (2) eight sessions of peer-delivered telephone support with DVD education; and (3) eight sessions of oncology nurse-delivered telephone counselling with DVD education. Two intervention sessions will be delivered before surgery and six over the six months post-surgery. The intervention will utilise a cognitive behavioural approach along with couple relationship education focussed on relationship enhancement and helping the couple to conjointly manage the stresses of cancer diagnosis and treatment. Participants will be assessed at baseline (before surgery) and 3, 6 and 12 months post-surgery. Outcome measures include: sexual adjustment; unmet sexuality supportive care needs; attitudes to sexual help seeking; psychological adjustment; benefit finding and quality of life. Discussion The study will provide recommendations about

    An outbreak of acute hepatitis C among HIV-positive men who have sex with men (MSM) in the last decade has been shown to be sexually transmitted. Initially recreational drug use, in particular drug injection, was not prevalent among those becoming infected with hepatitis C. However more recently chemsex (the use of drugs to enhance sexual experience) and its associated drugs, which are not uncommonly injected, have become more frequently reported among those diagnosed with hepatitis C. It is hoped that the widespread -introduction of direct-acting antivirals and upscaling of numbers treated may have a positive impact on this epidemic. However their introduction may negatively impact on the perceived risk of acquiring hepatitis C and in conjunction with the introduction of HIV transmission prevention strategies may result in increased transmissions and spread to the HIV-negative MSM population.

    Background: Infection risks among people who inject drugs (PWID) are widely recognized, but few studies have focused on image and performance enhancing drugs (IPEDs). Globally, concern about IPED injection has increased and, in the United Kingdom, IPED injectors have become the largest group using Needle and Syringe Programmes. Blood-borne virus prevalence trends among IPED injectors are explored. Method: Data from 2 surveys of IPED injectors (2010–2011; 2012–2013) and the national bio-behavioral surveillance system for PWID (1992–1997; 1998–2003; 2004–2009) were merged. Psychoactive drug injectors and women were excluded. Logistic regression analyses explored temporal changes. Results: Between 1992 and 2009, median age increased from 25 to 29 years (N = 1296), years injecting from 2 to 4. There were 53 men who had sex with men (MSM). Overall, 0.93% had HIV, 4.4% ever had hepatitis B (HBV), and 3.9% hepatitis C (HCV, from 1998, N = 1083). In multivariable analyses, HIV increased in 2004–2009 [adjusted odds ratio (AOR) = 10 (95% confidence interval (CI): 0.94 to 106) vs. 1992–2003], and remained elevated (AOR = 4.12, 95% CI: 0.31 to 54, 2012–2013); HBV also increased in 2004–2009 (AOR = 3.98, 95% CI: 1.59 to 9.97). HCV prevalence increase was only borderline significant (AOR = 2.47, 95% CI: 0.90 to 6.77, 2010–2011). HIV and HBV were associated with MSM and HCV with sharing needles/syringes. Uptake of diagnostic testing for HIV and HCV, and HBV vaccination increased (to 43%, 32% and 44% respectively). Condom use was consistently poor; needle/syringe sharing occurred. Conclusion: Blood-borne virus prevalences among IPED injectors have increased and for HIV, is now similar to that among psychoactive drug injectors. Targeted interventions to reduce risks are indicated. PMID:26361173

    Purpose: To evaluate the predictive performance of various parameters derived from volume-adjusted prostate-specific antigen (PSA) values in detecting prostate cancer (PCa) and high-grade (Gleason score≥7) PCa according to treatment with a 5α-reductase inhibitor (5ARI). Methods: The results of 3,520 prostate biopsies performed between May 2006 and January 2013 were retrospectively assessed. With adjustment for age, 291 patients who had received 5ARI treatment for more than 6 months were identified and matched 1:3 to patients naïve to 5ARIs, resulting in a total of 873 patients. Peripheral zone (PZ) and transition zone (TZ) volumes were determined by transrectal ultrasonography. Receiver-operating characteristic (ROC) curve analysis was used to compare predictive performances of PSA, PSA density (PSAD; PSA/prostate volume), PZPSAD (PSA/PZ volume), and TZPSAD (PSA/TZ volume) for detecting PCa and high-grade PCa for each group. Results: The area under the ROC curve (AUC) was higher for PSAD than for PSA in the 5ARI group (0.751 vs. 0.677) and in the 5ARI-naïve group (0.649 vs. 0.582), respectively (P<0.001). In the 5ARI group, the AUC for PZPSAD was even higher than that for PSAD (0.781 vs. 0.751, P=0.038); in the 5ARI-naïve group, however, PZPSAD failed to achieve significant superiority (0.652 vs. 0.649, P=0.321). All volume-adjusted PSA indexes showed higher predictive accuracies for detecting PCa than did PSA in both groups. For detecting high-grade cancer, PZPSAD also revealed the highest predictive value in the 5ARI group, whereas PSA revealed the highest predictive value in the 5ARI-naïve group. Conclusions: The diagnostic performance of PSAD in the detection of PCa is superior to that of PSA. For patients receiving 5ARI for more than 6 months, PZPSAD confers additional benefits for detecting both PCa and high-grade PCa. PMID:24223410

    Cambodian immigrants are over 25 times more likely to have evidence of chronic hepatitis B infection than the general US population. Carriers of HBV are over 100 times more likely to develop liver cancer than non-carriers. Liver cancer incidence is the second leading cancer for Cambodian men and the sixth for Cambodian women. Despite this, this underserved population has received very little attention from health disparities researchers. Culturally and linguistically appropriate interventions are necessary to increase hepatitis B knowledge, serologic testing, and vaccination among Cambodian Americans. Eight group interviews were held with Cambodian American men (48) and women (49). Focus group discussion revealed unanticipated information about sociocultural influences on participants’ understanding about hepatitis B transmission, disease course, and prevention and treatment informed by humoral theories underlying Khmer medicine, by biomedicine, and by migration experiences. Our findings reveal the value of qualitative exploration to providing cultural context to biomedical information—a formula for effective health promotion and practice. PMID:20496000

    Alcoholic hepatitis (AH) is an acute inflammatory syndrome causing significant morbidity and mortality. The prognosis is strongly dependent on disease severity, as assessed by clinical scoring systems. Reliable epidemiological data as well as knowledge of the clinical course of AH are essential for planning and resource allocation within the health care system. Likewise, individual evaluation of risk is desirable in the clinical handling of patients with AH as it can guide treatment, improve patient information, and serve as strata in clinical trials. The present PhD thesis is based on three studies using a cohort of nearly 2000 patients diagnosed with AH in Denmark from 1999 to 2008 as a cohort, in a population-based study design. The aims of this thesis were as follows. (1) To describe the incidence and short- and long-term mortality, of AH in Denmark (Study I). (2) To validate and compare the ability of the currently available prognostic scores to predict mortality in AH (Study II). (3) To investigate the short- and long-term causes of death of patients with AH (Study III). During the study decade, the annual incidence rate in the Danish population rose from 37 to 46 per 106 for men and from 24 to 34 per 106 for women. Both short- and long-term mortality rose for men and women, and the increase in short-term mortality was attributable to increasing patient age and prevalence of cirrhosis. Our evaluation of the most commonly used prognostic scores for predicting the mortality of patients with AH showed that all scores performed similarly, with Area under the Receiver Operator Characteristics curves giving values between 0.74 and 0.78 for 28-day mortality assessed on admission. Our study on causes of death showed that in the short-term (< 84 days after diagnosis), patients with AH were likely to die from liver-related events and infections. In the long-term (≥ 84 days after diagnosis), those who developed cirrhosis mainly died from liver-related causes, and

    Fish collected from the receiving areas of 12 Canadian pulp mills were examined, including sites receiving effluent from kraft mills using chlorine as well as sulfite mills. Field collections included sampling of receiving water for chemistry and toxicity testing, and sampling of local fish for organ weights, hepatic MFO (ethoxyresorufin-O-deethylase, EROD) activity, plasma steroid levels, and levels of liver dioxins. The main objectives of this study were to determine whether the discharge of effluent from pulp mills to sites other than Jackfish Bay was associated with physiological or biochemical disruptions in wild fish, whether there was any correlation between waste treatment and the presence of biological responses in wild fish, and whether there was any association between the use of chlorine as a bleaching agent and these responses. Although white sucker collected near bleached-kraft mills exhibited the highest EROD induction and dioxin levels, elevated enzyme activity was observed in fish from sites that did not use chlorine, and depressions in plasma sex steroid levels was not correlated with the level of EROD activity. The absence of chlorine bleaching or the presence of secondary treatment did not eliminate responses in fish, including decreased circulating levels of sex steroids, decreased gonadal size, and increase liver size. This survey has shown that (a) induction of hepatic EROD enzymes and depressions of plasma sex steroid levels during gonadal growth are found downstream of several pulp mills; (b) these changes are seen at some mills without chlorine bleaching and at mills that have secondary treatment; (c) substantial dilutions of nontoxic effluent do not appear to remove these responses; (d) the dominant factor determining the presence or absence of responses appeared to be dilution level; and (e) lab toxicity tests on invertebrates, rainbow trout, and fat-head minnows could not predict the presence of these responses in wild fish.

    Background: China is a country with a high prevalence of hepatitis B. As a special population, migrant workers are more vulnerable to hepatitis B. Objectives: The present study was conducted to gain insight into the prevalence of hepatitis B and knowledge about hepatitis B among migrant workers in Shandong Province, China, as well as to explore a series of strategies for preventing and controlling the spread and prevalence of hepatitis B. Patients and Methods: A cross-sectional study was conducted without age restriction, in Shandong Province in China. The sample-size was determined scientifically. The study population was selected using the random multistage cluster sampling. Personal information, including sex, age, ethnicity, marital status, education level, years of duration of stay in Jinan and health insurance were obtained from 2065 migrant workers. Moreover, blood samples were collected for hepatitis B infection screening. Knowledge about hepatitis B was assessed using a self-administered questionnaire. Correct response rates were calculated. Results: Of 2065 migrant workers tested for Hepatitis B Surface Antigen (HBsAg), 167 (126 men and 41 women) tested positive for HBsAg; the overall prevalence was 8.1%. The prevalence rates in men and women were 9.6% and 5.4%, respectively. The prevalence rates in subjects 18 - 30 years old and 30 years older were 3.5% and 9.3%, respectively. There were statistically significant differences between those groups (P < 0.05). Correct response rates for the transmission of hepatitis B questions were low, especially for a question regarding whether hepatitis B can be transferred by sexual contact (36.8%) and whether it can be transferred from mothers to infants (33.9%). A total of 80.9% of migrant workers correctly responded that vaccination is effective for hepatitis B. However, 68% of migrants also had the misconception that it is necessary to receive a booster vaccination. Conclusions: The hepatitis B virus infection rate

    This retrospective study evaluated the efficacy and tolerability of directly observed therapy with peginterferon alfa-2a and once-daily ribavirin (RBV) for chronic hepatitis C in 49 opioid-addicted injection drug users (IDUs) participating in a drug treatment program at a specialized outpatient center. Patients also received prophylactic citalopram to minimize the risk of interferon-induced depression. Patients had daily access to and support from specialist physicians, nurses and counseling services at the center, and a 24-hour helpline. Sustained virological response was achieved by 48 of 49 patients (98%) overall, including 20 of 21 (95%) hepatitis C virus (HCV) Genotype 1/4-infected patients and 28 of 28 (100%) Genotype 2/3-infected patients. Treatment was well tolerated, and no unexpected side effects of peginterferon treatment were seen. The safety profile of once-daily RBV was not different from twice-daily dosing. Decline in hemoglobin levels was similar to those reported in clinical trials including once-daily RBV and did not lead to dose reduction or treatment withdrawal. Our data demonstrate that HCV-infected IDUs on stable L-polamidone (methadone) or buprenorphine maintenance can be successfully and safely treated with peginterferon alfa-2a and RBV in an optimal substitution setting.

    Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant inherited syndrome characterized by multiple tumors in the parathyroid glands, endocrine pancreas and anterior pituitary. Recent clinical studies have revealed a strong association between MEN1 syndrome and the risk of developing diabetes mellitus; however, the underlying mechanisms remain unknown. In this study, heterozygous Men1 knockout (Men1(+/-)) mice were used as MEN1 models to investigate MEN1-associated glucose metabolic phenotypes and mechanisms. Heterozygous deficiency of Men1 in 12-month-old male mice induced fasting hyperglycemia, along with increased serum insulin levels. However, male Men1(+/-) mice did not show insulin resistance, as evidenced by Akt activation in hepatic tissues and an insulin tolerance test. Increased glucose levels following pyruvate challenge and expression of key gluconeogenic genes suggested increased hepatic glucose output in the male Men1(+/-) mice. This effect could be partly due to higher basal serum glucagon levels, which resulted from pancreatic islet cell proliferation induced by heterozygous loss of Men1 Taken together, our results indicate that fasted male Men1(+/-) mice, in the early stage of development of MEN1, display glucose metabolic disorders. These disorders are caused not by direct induction of insulin resistance, but via increased glucagon secretion and the consequent stimulation of hepatic glucose production. PMID:27432891

    During World War II, nearly all US and Allied troops received yellow fever vaccine. Until May 1942, it was both grown and suspended in human serum. In April 1942, major epidemics of hepatitis occurred in US and Allied troops who had received yellow fever vaccine. A rapid and thorough investigation by the US surgeon general followed, and a directive was issued discontinuing the use of human serum in vaccine production. The large number of cases of hepatitis caused by the administration of this vaccine could have been avoided. Had authorities undertaken a thorough review of the literature, they would have discovered published reports, as early as 1885, of postvaccination epidemics of hepatitis in both men and horses. It would take 4 additional decades of experiments and epidemiological research before viruses of hepatitis A, B, C, D, and E were identified, their modes of transmission understood, and their genomes sequenced.

    Polymorphisms of the ITPA gene have been associated with anemia during combination therapy in hepatitis C virus (HCV)-monoinfected patients. Our aim was to confirm this association in HIV/HCV-coinfected patients. In this prospective, observational study, 73 HIV/HCV-coinfected patients treated with pegylated interferon plus ribavirin (RBV) were enrolled. Two single nucleotide polymorphisms within or adjacent to the ITPA gene (rs1127354 and rs7270101) were genotyped. The associations between the ITPA genotype and anemia or treatment outcome were examined. Fifty-nine patients (80.8%) had CC at rs1127354, whereas 14 (19.2%) had a CA/AA ITPA genotype. Percent decreases from baseline hemoglobin level were significantly greater in patients with the CC genotype than in those with the CA/AA genotype at week 4 (P = 0.0003), week 12 (P < 0.0001), and week 36 (P = 0.0102) but not at the end of treatment. RBV dose reduction was more often needed in patients with the CC genotype than in those with the CA/AA genotype (odds ratio [OR] = 11.81; 95% confidence interval [CI] = 1.45 to 256.17; P = 0.0039), as was erythropoietin therapy (OR = 8.28; 95% CI = 1.04 to 371.12; P = 0.0057). Risk factors independently associated with percent hemoglobin nadir decrease were RBV dose reduction (OR = 11.72; 95% CI = 6.82 to 16.63; P < 0.001), baseline hemoglobin (OR = 1.69; 95% CI = 0.23 to 3.15; P = 0.024), and body mass index (OR = -0.7; 95% CI = -1.43 to 0.03; P = 0.061). ITPA polymorphism was not an independent predictor of sustained virological response. Polymorphisms at rs1127354 in the ITPA gene influence hemoglobin levels during combination HCV therapy and the need for RBV dose reduction and erythropoietin use in HIV/HCV-coinfected patients.

    More than 500,000 people in Germany have chronic viral hepatitis. The interferon-based treatments formerly used in hepatitis B have been widely replaced by life-long oral medication with nucleoside or nucleotide analogues. Treatment for chronic hepatitis C has been improved substantially by the development of new and very expensive drug combinations. Up to 90% of patients can now be cured with certainty, and one to two years after successful treatment there is no relevant risk of recurrence. These individuals expect to receive insurance cover under appropriate conditions. Vaccination programmes are very efficient at decreasing the incidence of hepatitis B, but no vaccine against hepatitis C is likely to become available in the next decade. PMID:27111951

    The risk of hepatitis B among men having sex with men (MSM) is high, with core antibody rates ranging from 5% to 81%. We describe an outreach, hepatitis B vaccination programme aiming to raise awareness of hepatitis B and increase vaccination uptake. The 13-week programme used an ultra rapid vaccination schedule. Follow-up was defined as complete if the client was core antibody positive, had adequate surface antibody levels following prior vaccination or received three vaccine doses. One hundred and fifty clients were screened for hepatitis B and syphilis. Three cases of untreated syphilis (early latent) and one case of e-antigen-positive hepatitis B were detected. With the aid of text-message reminders, a vaccination completion rate of 76.6% was achieved, with 82.5% completing follow-up. In conclusion, this programme succeeded in reaching MSM not routinely accessing services. Text messaging was an acceptable and effective method of follow-up, resulting in high vaccination completion rates. PMID:17524195

    A description is given for an improved calutron receiver having a face plate lying at an angle to the direction of the entering ion beams but having an opening, the plane of which is substantially perpendicular to that of the entering ion beams. By so positioning the opening in the receiver, the effective area through which the desired material may enter the receiver is increased, and at the same time the effective area through which containattng material may enter the receiver is reduced.

    A receiver construction is presented for calutrons having two or more ion sources and an individual receiver unit for each source. Design requirements dictate that the face plate defining the receiver entrance slots be placed at an angle to the approaching beam, which means that ions striking the face plate are likely to be scattcred into the entrance slots of other receivers. According to the present invention, the face plate has a surface provided with parallel ridges so disposed that one side only of each ridge's exposed directly to the ion beam. The scattered ions are directed away from adjacent receivers by the ridges on the lace plate.

    2016-01-01

    Background Most studies on the relationships between metabolic disorders (hypertension, dyslipidemia, and impaired glucose tolerance) and hepatic steatosis (HS) or visceral fat accumulation (VFA) have been cross-sectional, and thus, these relationships remain unclear. We conducted a retrospective cohort study to clarify the relationships between components of metabolic disorders and HS/VFA. Methods The participants were 615 middle-aged men who were free from serious liver disorders, diabetes, and HS/VFA and underwent multiple general health check-ups at our institution between 2009 and 2013. The data from the initial and final check-ups were used. HS and VFA were assessed by computed tomography. HS was defined as a liver to spleen attenuation ratio of ≤1.0. VFA was defined as a visceral fat cross-sectional area of ≥100 cm2 at the level of the navel. Metabolic disorders were defined using Japan’s metabolic syndrome diagnostic criteria. The participants were divided into four groups based on the presence (+) or absence (-) of HS/VFA. The onset rates of each metabolic disorder were compared among the four groups. Results Among the participants, 521, 55, 24, and 15 were classified as HS(-)/VFA(-), HS(-)/VFA(+), HS(+)/VFA(-), and HS(+)/VFA(+), respectively, at the end of the study. Impaired glucose tolerance was more common among the participants that exhibited HS or VFA (p = 0.05). On the other hand, dyslipidemia was more common among the participants that displayed VFA (p = 0.01). Conclusions It is likely that VFA is associated with impaired glucose tolerance and dyslipidemia, while HS might be associated with impaired glucose tolerance. Unfortunately, our study failed to detect associations between HS/VFA and metabolic disorders due to the low number of subjects that exhibited fat accumulation. Although our observational study had major limitations, we consider that it obtained some interesting results. HS and VFA might affect different metabolic disorders

    Homosexuality is a global human phenomenon. Although the American Psychiatric Association removed homosexuality from its list of disorders more than 35years ago, homophobia among physicians is still widely prevalent. Men who have sex with men (MSM) form a relatively new epidemiological risk group for STI. To perform correct management, clinicians evaluating men with male-male sex contacts for STI related complaints or STI screening must obtain a thorough sexual history. Emerging STI like lymphogranuloma venereum, hepatitis C, and multidrug resistant N. gonorrhea strains have been described first in MSM. STI related proctitis often occur in MSM. Within the MSM population, HIV positive patients form a special group affected by STI related diseases, such as anal carcinoma and neurosyphilis. The final part of this review concludes with recommendations to reduce the STI burden in MSM. PMID:24559552

    Men who have sex with men (MSM) are at high risk for disease associated with human papillomavirus (HPV). In late 2011, HPV vaccine was recommended for males through age 21 and MSM through age 26. Using data from the 2011 National HIV Behavioral Surveillance System, we assessed self-reported HPV vaccine uptake among MSM, using multivariate analysis to calculate adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs). Among 3221 MSM aged 18–26, 157 (4.9%) reported ≥1 vaccine dose. Uptake was higher among men who visited a healthcare provider (aPR 2.3, CI: 1.2–4.2), disclosed same-sex sexual attraction/behavior to a provider (aPR 2.1, CI: 1.3–3.3), reported a positive HIV test (aPR 2.2, CI: 1.5–3.2), or received hepatitis vaccine (aPR 3.9, CI: 2.4–6.4). Of 3064 unvaccinated MSM, 2326 (75.9%) had visited a healthcare provider within 1 year. These national data on HPV vaccine uptake among MSM provide a baseline as vaccination recommendations are implemented. PMID:25258097

    A novel calutron receiver is described for collecting the constituent material of two closely adjacent selected portions of an ion beam in separate compartments. The receiver is so conntructed that ion scatter and intermixing of the closely adjacent beam portions do nnt occur when the ions strike the receiver structure, and the beam is sharply separated Into the two compartments. In essence, these desirable results are achieved by inclining the adjoining wall of one compartment with respect to the approaching ions to reduce possible rebounding of ions from the compartment into the adjacent compartment.

    Kaposi's sarcoma-associated herpesvirus (KSHV), the etiologic agent of Kaposi's sarcoma, causes malignancies frequently in patients with acquired immunodeficiency syndrome. In the United States and Europe, KSHV infection is common among men who have sex with men. However, the seroprevalence of KSHV among men who have sex with men in Japan is unknown. In the present study, the seroprevalence of KSHV was investigated among 230 men who have sex with men and 400 age- and area of residence-matched men (controls) using a mixed-antigen (KSHV-encoded K8.1, open reading frame 59, 65, and 73 proteins) enzyme-linked immunosorbent assay and an immunofluorescence assay. Among the Japanese men who have sex with men, serological assays revealed that 27 (11.7%) were seropositive for KSHV; 20 (5%) of the men in the control group were also KSHV seropositive. The seroprevalence of KSHV among men who have sex with men was significantly higher than in the control group (odds ratio = 2.52, 95% confidence intervals = 1.38-4.62, P = 0.0019, Chi-square test). Infection with the human immunodeficiency virus, Treponema pallidum, or hepatitis B and C virus did not correlate with KSHV infection. Furthermore, the association of KSHV seropositivity with specific sexual activities was not statistically significant. In conclusion, a higher KSHV seroprevalence was found among Japanese men who have sex with men than among the controls, suggesting that the circulation of KSHV infection is more efficient among men who have sex with men in Japan than among men who do not engage in such sexual activities.

    Recent reports have suggested an increased risk of acute hepatitis C (AHC) infection in homosexual HIV-infected men and that early treatment with interferon-alfa, alone or associated with ribavirin, significantly reduces the risk of chronic evolution. A retrospective analysis of 38 HIV-infected patients who were consecutively diagnosed as developing AHC, defined by both seroconversion of anti-hepatitis C virus (HCV) antibodies and detection of serum HCV-RNA in those with previous negative results. Thirty-six patients were men with history of unprotected sexual intercourse with men and two were women with sexual and nosocomial risk factors. AHC infection was asymptomatic in 26 patients; asthenia and jaundice were the most frequent symptoms. HCV genotype 1 was present in 19 patients and genotype 4 in 14 patients. Thirty-five patients received early antiviral treatment with pegylated interferon-alfa associated with ribavirin; 15 of the 32 patients who completed the follow-up (47%) achieved a sustained virological response, as defined by undetectable HCV-RNA 6 months after the end of therapy. There is a risk of sexual transmission of HCV in HIV-infected men who have sex with men. In our experience, early treatment of AHC with pegylated interferon-alfa plus ribavirin in HIV patients achieves poor results. PMID:22428909

Given the lack of a hepatitis C vaccine, the many challenges facing the production of a hepatitis C vaccine will be shown, along with current and former vaccination trials. As there is no current FDA-approved hepatitis E vaccine, we will present vaccination data that is available in the rest of the world. Finally, we will discuss the existing challenges and questions facing future endeavors for each of the hepatitis viruses, with efforts continuing to focus on dramatically reducing the morbidity and mortality associated with these serious infections of the liver.

    Hepatitis B (HBV) and hepatitis C (HCV) reactivation may occur after the use of biologic agents. During the last decade, utilization of biologics has changed the fate of many treated for cancer, autoimmune and connective tissue disease, maintenance of transplanted organs, and the prevention of graft-versus-host disease among others. HBV reactivation has been reported in up to 50% of HBV carriers undergoing immunosuppressive therapy, and there is emerging data pointing towards an increased risk for HCV reactivation. If reactivation of HBV and HCV occurs, the spectrum of clinical manifestations can range from asymptomatic hepatitis flares to hepatic decompensation, fulminant hepatic failure, and death. Therefore, identifying patients at risk and early diagnosis are imperative to decrease significant morbidity and mortality. The purpose of this article is to review the pathophysiology of the reactivation of HBV and HCV infection in patients receiving biologic therapies and the approaches used to diagnose, prevent, and treat HBV and HCV reactivation.

The electromagnetic separation of the isotopes produces a mass spectrum of closely adjacent beams of ions at the foci regions, and a dividing wall between the two pockets is arranged at an angle. Substantially all of the tons of the less abundant isotope enter one of the pockets and strike one side of the wall directly, while substantially none of the tons entering the other pocket strikes the wall directly.

    Intramuscular administration of hepatitis B (HB) vaccine is safe and efficacious, but its cost has limited its availability. In this pilot study, 49 of 56 participants who received 2 μg of intradermal (ID) HB vaccine (one tenth the intramuscular dose) at the beginning of administration, at 1 month, and at 6 months developed protective levels of antibody to HB surface antigen. Although questions remain, the cost savings of this technique make it worth considering. PMID:21229118

    Chronic liver disease and cirrhosis affect hundreds of millions of patients all over the world. The majority of patients with cirrhosis will eventually develop complications related to portal hypertension. One of these recurrent and difficult to treat complications is hepatic encephalopathy. Studies have indicated that overt hepatic encephalopathy affects 30 to 45% of patients with cirrhosis and a higher percentage may be affected by minimal degree of encephalopathy. All of these factors add to the impact of hepatic encephalopathy on the healthcare system and presents a major challenge to the gastroenterologist, hospitalist and primary care physician.

  3. Hepatitis B immunization in adolescents.

    Lawrence, M H; Goldstein, M A

    1995-10-01

    This article reviews the epidemiology of hepatitis B in the United States, previous vaccination strategy, and reasons for its failure and issues leading to the recommendation to vaccinate all adolescents. A review of specific hepatitis B virus risk behaviors of adolescents and barriers to vaccinating adolescents is covered. Strategies that favor successful completion of the immunization series are also examined. Hepatitis B infection is an important public health concern for adolescents. The previous vaccine strategy to immunize only individuals though to be at high risk was unsuccessful, especially because providers of care could not identify these individuals. Furthermore, many individuals thought not to be at high risk for infection were exposed through contacts which could not be identified. Challenges to immunization of adolescents include logistical issues, patient education, cost of the vaccine, and patient compliance. Several of these issues can be addressed by a school-based hepatitis B immunization program. The body of evidence and national policy is rapidly changing to support the recommendation that all adolescents receive the hepatitis B immunization series. The series would be most effective if administered during the middle-school years. A universal adolescent hepatitis B vaccination program would result in the most immediate health benefits and acceleration toward the eradication of hepatitis B in the United States. PMID:8580124

    The apparatus for collecting radiant energy and converting same to alternate energy form includes a housing having an interior space and a radiation transparent window allowing, for example, solar radiation to be received in the interior space of the housing. Means are provided for passing a stream of fluid past said window and for injecting radiation absorbent particles in said fluid stream. The particles absorb the radiation and because of their very large surface area, quickly release the heat to the surrounding fluid stream. The fluid stream particle mixture is heated until the particles vaporize. The fluid stream is then allowed to expand in, for example, a gas turbine to produce mechanical energy. In an aspect of the present invention properly sized particles need not be vaporized prior to the entrance of the fluid stream into the turbine, as the particles will not damage the turbine blades. In yet another aspect of the invention, conventional fuel injectors are provided to inject fuel into the fluid stream to maintain the proper temperature and pressure of the fluid stream should the source of radiant energy be interrupted. In yet another aspect of the invention, an apparatus is provided which includes means for providing a hot fluid stream having hot particles disbursed therein which can radiate energy, means for providing a cooler fluid stream having cooler particles disbursed therein, which particles can absorb radiant energy and means for passing the hot fluid stream adjacent the cooler fluid stream to warm the cooler fluid and cooler particles by the radiation from the hot fluid and hot particles. 5 figs.

    Behavioral and physiological data suggest that the striatal dopaminergic system is important in the production and execution of sequential movements. Striatal function is also modulated by sex hormones, and previous studies show that estradiol is related to sequential movement in women. The authors examined whether sex hormones are involved in the production of sequential movement in healthy older and younger men. Testosterone was modified for a 6-week period such that levels in older men matched those of younger men, the conversion of testosterone to estradiol was blocked, the production of testosterone was blocked, or the men received no treatment (placebo). Sequential movement was measured before and after hormone treatment. Older men were slower and more accurate than younger men on the sequential movement task pre- and posttreatment. Hormone manipulation had no effect on movement speed. Hormone levels were not correlated with sequential movement performance in either older or younger men, suggesting that sex hormones do not modulate sequential movement in men, and hormone replacement may not restore a loss of sequential movement ability in elderly men or men with Parkinson's disease.

    Hepatitis C Virus (HCV) infection is a major cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Following acute infection, 20% of people eliminate the virus over weeks or months and are often asymptomatic. The remaining 80% of people will develop chronic disease, of which approximately 20% will eventually develop liver cirrhosis and 1–5% will develop liver cancer. About 150 million people are chronically infected with HCV, and more than 350 000 people die every year from hepatitis C related liver diseases. The economic cost of hepatitis C is significant both to the individual and to the society. In the United States the average lifetime cost of the disease was estimated at $33 407 USD with the cost of a liver transplant approximately $200 000 USD. PEG-IFN and ribavirin treatment is also expensive and, at an average cost of approximately GB £7000 in the UK for a treatment course, is unaffordable in developing countries. Hepatitis C, not only brings down the quality of the life of individuals but also affect progress of the nation by adding financial burden. If we prevent the disease from occurring or find a perfect cure of the disease, in form of a prophylactic or therapeutic vaccine, it will be a boon to not only to the individual but to the nation as a whole.

    OBJECTIVE Hepatic steatosis is common in type 2 diabetes. It is causally linked to the features of the metabolic syndrome, liver cirrhosis, and cardiovascular disease. Experimental data have indicated that increased liver fat may impair hepatic perfusion and metabolism. The aim of the current study was to assess hepatic parenchymal perfusion, together with glucose and fatty acid metabolism, in relation to hepatic triglyceride content. RESEARCH DESIGN AND METHODS Fifty-nine men with well controlled type 2 diabetes and 18 age-matched healthy normoglycemic men were studied using positron emission tomography to assess hepatic tissue perfusion, insulin-stimulated glucose, and fasting fatty acid metabolism, respectively, in relation to hepatic triglyceride content, quantified by proton magnetic resonance spectroscopy. Patients were divided into two groups with hepatic triglyceride content below (type 2 diabetes-low) or above (type 2 diabetes-high) the median of 8.6%. RESULTS Type 2 diabetes-high patients had the highest BMI and A1C and lowest whole-body insulin sensitivity (ANOVA, all P < 0.001). Compared with control subjects and type 2 diabetes-low patients, type 2 diabetes-high patients had the lowest hepatic parenchymal perfusion (P = 0.004) and insulin-stimulated hepatic glucose uptake (P = 0.013). The observed decrease in hepatic fatty acid influx rate constant, however, only reached borderline significance (P = 0.088). In type 2 diabetic patients, hepatic parenchymal perfusion (r = −0.360, P = 0.007) and hepatic fatty acid influx rate constant (r = −0.407, P = 0.007) correlated inversely with hepatic triglyceride content. In a pooled analysis, hepatic fat correlated with hepatic glucose uptake (r = −0.329, P = 0.004). CONCLUSIONS In conclusion, type 2 diabetic patients with increased hepatic triglyceride content showed decreased hepatic parenchymal perfusion and hepatic insulin mediated glucose uptake, suggesting a potential modulating effect of hepatic fat

    We measured interferon γ–induced protein 10 (IP-10) levels in 428 patients at baseline, week 1, and week 2 of all-oral treatment for hepatitis C virus (HCV) infection. An increased baseline IP-10 level was associated with a T allele in the IL28B gene, an increased alanine aminotransferase level in treatment-naive but not experienced patients, and an increased body mass index. At week 1, the mean decline in plasma IP-10 levels was the same in treatment-naive and treatment-experienced patients (−49%), whereas during week 2 the mean decline in IP-10 levels in treatment-naive patients (−14%) was significantly larger than in treatment-experienced patients (−2%; P = .0176). IP-10 thus may be a surrogate marker of the rate of intracellular viral replication complex decay. PMID:24907384

  4. Hepatic encephalopathy.

    PubMed

    Córdoba, Juan; Mínguez, Beatriz

    2008-02-01

    Hepatic encephalopathy is a severe complication of cirrhosis that is related to the effects of ammonia. Analysis of interorgan ammonia trafficking has identified an important role of skeletal muscle in ammonia removal and has highlighted the importance of the nutritional status. Ammonia causes neurotransmitter abnormalities and induces injury to astrocytes that is partially mediated by oxidative stress. These disturbances lead to astrocyte swelling and brain edema, which appear to be involved in the pathogenesis of neurological manifestations. Inflammatory mediators worsen brain disturbances. New methods for assessing hepatic encephalopathy include clinical scales, neuropsychological tests, imaging of portal-systemic circulation, and magnetic resonance of the brain. Reappraisal of current therapy indicates the need for performing placebo-controlled trials and the lack of evidence for administering diets with restricted protein content. Liver transplant should be considered in selected patients with hepatic encephalopathy. Future prospects include new drugs that decrease plasma ammonia, measures to reduce brain edema, and liver-support devices. PMID:18293278

    Hepatic encephalopathy (EH) is a severe complication of hepatic cirrhosis that is characterized by multiple neuropsychiatric manifestations. EH is usually triggered by a precipitating factor and occurs in patients with severely impaired hepatic function. Minimal EH is characterized by minor cognitive impairments that are difficult to specify but represent a risk for the patients. The primary pathophysiological mechanism of EH is considered to be an increase in blood ammonia with an impairment in the patency of the blood-brainbarrier and its metabolism to glutamine in astrocytes. The diagnosis is clinical and neuroimaging techniques can be complementary. The diagnosis of minimal EH requires specific neurocognitive tests. The clinical evaluation should be directed towards identifying the trigger. Nonabsorbable disaccharides and rifaximin constitute the treatment of choice, along with prophylaxis for new episodes.

    Objective Formulae used to estimate glomerular filtration rate (GFR) underestimate higher GFRs and have not been well-studied in HIV-infected (HIV(+)) people; we evaluated the relationships of HIV infection and known or potential risk factors for kidney disease with directly measured GFR and the presence of chronic kidney disease (CKD). Design Cross-sectional measurement of iohexol-based GFR (iGFR) in HIV(+) men (n = 455) receiving antiretroviral therapy, and HIV-uninfected (HIV(−)) men (n = 258) in the Multicenter AIDS Cohort Study. Methods iGFR was calculated from disappearance of infused iohexol from plasma. Determinants of GFR and the presence of CKD were compared using iGFR and GFR estimated by the CKD-Epi equation (eGFR). Results Median iGFR was higher among HIV(+) than HIV(−) men (109 vs. 106 ml/min/1.73 m2, respectively, p = .046), and was 7 ml/min higher than median eGFR. Mean iGFR was lower in men who were older, had chronic hepatitis C virus (HCV) infection, or had a history of AIDS. Low iGFR (≤90 ml/min/1.73 m2) was associated with these factors and with black race. Other than age, factors associated with low iGFR were not observed with low eGFR. CKD was more common in HIV(+) than HIV(−) men; predictors of CKD were similar using iGFR and eGFR. Conclusions iGFR was higher than eGFR in this population of HIV-infected and -uninfected men who have sex with men. Presence of CKD was predicted equally well by iGFR and eGFR, but associations of chronic HCV infection and history of clinically-defined AIDS with mildly decreased GFR were seen only with iGFR.

    Acute viral hepatitis affects all ages worldwide. Hepatitis E virus (HEV) is increasingly recognized as a major cause of acute hepatitis in Europe. Because knowledge of its characteristics is limited, we conducted a retrospective study to outline demographic and clinical features of acute HEV in comparison to hepatitis A, B and C in Lothian over 28 months (January 2012 to April 2014). A total of 3204 blood samples from patients with suspected acute hepatitis were screened for hepatitis A, B and C virus; 913 of these samples were also screened for HEV. Demographic and clinical information on patients with positive samples was gathered from electronic patient records. Confirmed HEV samples were genotyped. Of 82 patients with confirmed viral hepatitis, 48 (59%) had acute HEV. These patients were older than those infected by hepatitis A, B or C viruses, were more often male and typically presented with jaundice, nausea, vomiting and/or malaise. Most HEV cases (70%) had eaten pork or game meat in the few months before infection, and 14 HEV patients (29%) had a recent history of foreign travel. The majority of samples were HEV genotype 3 (27/30, 90%); three were genotype 1. Acute HEV infection is currently the predominant cause of acute viral hepatitis in Lothian and presents clinically in older men. Most of these infections are autochthonous, and further studies confirming the sources of infection (i.e. food or blood transfusion) are required. PMID:26904201

    A yeast-recombinant hepatitis B vaccine was licensed recently by the Food and Drug administration and is now available. To assess the efficacy of the yeast-recombinant vaccine, the authors administered the vaccine in combination with hepatitis B immune globulin to high-risk newborns. If infants whose mothers were positive for both hepatitis B surface antigen and the e antigen receive no immunoprophylaxis, 70% to 90% become infected with the virus, and almost all become chronic carriers. Among infants in this study who received hepatitis B immune globulin at birth and three 5-/sup +/g doses of yeast-recombinant hepatitis B vaccine, only 4.8% became chronic carriers, a better than 90% level of protection and a rate that is comparable with that seen with immune globulin and plasma-derived hepatitis B vaccine. Hepatitis surface antigen and antibodies were detected by radioimmunoassay. These data suggest that, in this high-risk setting, the yeast-recombinant vaccine is as effective as the plasma-derived vaccine in preventing hepatitis B virus infection and the chronic carrier state.

    Primary hepatic lymphoma (PHL) is a lymphoproliferative disorder confined to the liver without evidence of involvement of spleen, lymph nodes, bone marrow or other lymphoid structures. This is in contrast to Non Hodgkin's Lymphoma (NHL) that often involves the liver as a secondary manifestation. PHL is a rare disease and constitutes 0.016% of all cases of NHL. PHL typically occurs in middle aged men, and usually the chief presenting symptoms are non specific which includes right upper quadrant pain, B symptoms like fever and weight loss and constitutional symptoms. Most frequent physical finding is hepatomegaly which occurs in 75% of patients. Jaundice is rare and present only in less than 5% of patients. Majority of PHL originates from B cells. The blood investigations and imaging findings are nonspecific. Histopathology is essential and confirms the diagnosis. Treatment modalities include combination of surgical resection, chemotherapy and radiotherapy. The prognosis without therapy is grim. The prognosis and management of PHL is different from hepatocellular carcinoma or metastatic disease, hence it is essential to differentiate it from these diseases. The purpose of this review is to emphasize the importance of accurate diagnosis before implementing therapeutic plan for any hepatic space occupying lesion in liver. PMID:26591949

  14. Sexual transmission of hepatitis C and early intervention.

    The major risk factors for the transmission of hepatitis C virus (HCV) have been sharing needles for intravenous drug use (IDU) and receiving blood and blood products; however, recent findings suggest that HCV is being increasingly sexually transmitted, particularly among HIV-positive men who engage in high-risk, unprotected sexual behaviors with other men. Sixteen HIV-positive patients were diagnosed with sexually acquired HCV infection at a leading London HIV outpatient treatment center during 2002. All 16 patients were homosexual males with no history of IDU who had been involved in high-risk, unprotected sexual behaviors, which included active and passive anal intercourse, fisting, rimming, and oral sex. Six patients (37.5%) in the cohort spontaneously cleared HCV infection and consequently tested negative for HCV RNA. The remaining 10 patients were all started on HCV treatment, which consisted of pegylated interferon alpha-2b in combination with ribavirin. Three patients (43%) have achieved a significant reduction in HCV RNA after 12 to 24 weeks of HCV treatment. The earlier HCV seroconversion is detected and treated, the better the chance of achieving viral eradication. PMID:14571563

Patients with a diagnosis of hepatic cirrhosis were included and stratified using their Child-Pugh score. Biochemical parameters were evaluated, and ultrasound was used to measure the longest diameter of the spleen. The platelet count/spleen diameter ratio was calculated and analyzed to determine whether it can predict the presence of esophageal varices. Upper gastrointestinal endoscopy was used as the gold standard. Sensitivity and specificity, positive and negative predictive values, and positive and negative likelihood ratios were determined, with the cutoff points determined by receiver-operating characteristic curves. RESULTS: A total of 91 patients were included. The mean age was 53.75 ± 12 years; 50 (54.9%) were men, and 41 (45.0%) women. The etiology of cirrhosis included alcohol in 48 (52.7%), virally induced in 24 (26.3%), alcoholism plus hepatitis C virus in three (3.2%), cryptogenic in nine (9.8%), and primary biliary cirrhosis in seven (7.6%). Esophageal varices were present in 73 (80.2%) patients. Child-Pugh classification, 17 (18.6%) patients were classified as class A, 37 (40.6%) as class B, and 37 (40.6%) as class C. The platelet count/spleen diameter ratio to detect esophageal varices independent of the grade showed using a cutoff value of ≤ 884.3, had 84% sensitivity, 70% specificity, and positive and negative predictive values of 94% and 40%, respectively. CONCLUSION: Our results suggest that the platelet count/spleen diameter ratio may be a useful tool for detecting esophageal varices in patients with hepatic cirrhosis. PMID:24616574

    Hepatic encephalopathy is a severe complication of liver cirrhosis and is an important therapeutic challenge, with a social and economic issue. If, now, the pathophysiology is not totally understood (main role of ammonia, but a better understanding of cerebral mechanisms), the clinical presentation is well-known. Some treatments are useful (disaccharides, treatment of the trigger) but their efficiency is limited. Nevertheless, the emergence of new treatments, such as non-absorbable antibiotics (rifaximin essentially), is an interesting therapeutic tool. PMID:26597584

    Hepatitis E viral infection has traditionally been considered an acute, self-limited, water borne disease similar to hepatitis A, endemic to developing countries. However, over the past decade, zoonotic transmission and progression to chronicity in human patients has been identified, resulting in persistently elevated transaminase levels, progressive liver injury and cirrhosis. In addition to liver injury, neurological, renal and rheumatological manifestations have also been reported. Chronic hepatitis E occurs mainly in immunosuppressed individuals such as transplant recipients, human immunodeficiency virus patients with low CD4 counts and in patients with hematological malignancies receiving chemotherapy. Diagnosis is established by persistent elevation of hepatitis E virus RNA in the stool or serum. This population often requires treatment with antiviral agents, particularly ribavirin, as spontaneous clearance with reduction in immunosuppression occurs only in about a third of the patients. The purpose of this review, is to further discuss the clinical presentation, and recent advances in diagnosis, treatment and prophylaxis of chronic hepatitis E. PMID:26380044

    AIM: Hepatic cavernous hemangioma (HCH) is the most common benign tumor of the liver and its management is still controversial. Recent success in situ radiofrequency ablation of hepatic malignancies has led us to consider using this technique in patients with HCH. This study was to assess the efficacy, safety, and complications of percutaneous radiofrequency ablation (PRFA) under ultrasonography guidance in patients with HCH. METHODS: Twelve patients (four men and eight women, age ranged 33-56 years, mean age was 41.7 years) with 15 hepatic cavernous hemangiomas (2.5 cm to 9.5 cm) were treated using the RF-2000 generator and 10-needle LeVeen electrode percutaneously guided by B-ultrasound. Lesions larger than 3 cm were treated by multiple overlapping ablations that encompass the entire lesion as well as a rim of normal liver tissue (approximately 0.5 cm). RESULTS: All the patients who received PRFA therapy had no severe pain, bleeding or bile leakage during and after the procedures. Nine to 34 months’ follow-up (mean, 21 months) by ultrasound and/or spiral CT scan demonstrated that the ablated lesions in this group were shrunk remarkably, and the shrunken range was 38%-79% (mean, 67% per 21 months). The contrast enhancement was disappeared within the tumor or at its periphery in all cases on spiral CT scans obtained 3 to 6 months after treatment. CONCLUSION: The results of this study suggest that PRFA therapy is a mini-invasive, simple, safe, and effective method for the treatment of selected patients with HCH. PMID:12970923

    Lamivudine has been shown to prevent de novo hepatitis B virus (HBV) infections in liver transplantation (LT) patients receiving hepatitis B core antibody-positive (HBcAb(+)) grafts, but it may produce long-term resistance. Adefovir dipivoxil (ADV) might be effective in preventing de novo hepatitis and resistance. A single-center, prospective trial was conducted with 16 adults (10 men and 6 women, mean age = 54 ± 11 years) who underwent LT with HBcAb(+) grafts between September 2007 and October 2009. After LT, patients were given ADV [10 mg daily (adjusted for renal function)]. No hepatitis B immune globulin was administered. At LT, all graft recipients were hepatitis B surface antigen-negative (HBsAg(-)), 38% were surface antibody-positive (HBsAb(+)), and 50% were HBcAb(+). The median follow-up after LT was 1.8 years (range = 1.0-2.6 years). All recipients had undetectable HBV DNA (<40 IU/mL) after LT until the end of follow-up. One recipient (6%) who was HBsAb(-) and HBcAb(-) before LT became HBsAg(+) after 52 weeks. One recipient was switched from ADV to entecavir for chronic renal insufficiency, and 19% of the patients had renal dose adjustments. There was a nonsignificant trend of increasing creatinine levels over time (1.2 mg/dL at LT, 1.3 mg/dL 1 year after LT, and 2.0 mg/dL 2 years after LT, P = 0.27). A comparison with a control cohort of LT recipients with hepatitis C virus who did not receive ADV showed no difference in the creatinine levels at LT or 1 year after LT. In conclusion, ADV prophylaxis prevents HBV replication in recipients of HBcAb(+) livers but does not fully protect recipients from de novo HBV. Long-term follow-up is needed to better determine the risk of de novo infection. PMID:22422699

    Hepatic encephalopathy is a challenging complication in patients with advanced liver disease. It can be defined as a neuropsychiatric syndrome caused by portosystemic venous shunting, ranging from minimal to overt hepatic encephalopathy or coma. Its pathophysiology is still unclear, although increased levels of ammonia play a key role. Diagnosis of hepatic encephalopathy is currently based on specific tests evaluating the neuropsychiatric state of patients and their quality of life; the severity of hepatic encephalopathy is measured by the West Haven criteria. Treatment of hepatic encephalopathy consists of pharmacological and corrective measures, as well as nutritional interventions. Rifaximin received approval for the treatment of hepatic encephalopathy in 2010 because of its few side effects and pharmacological benefits. The aim of this work is to review the use and efficacy of rifaximin both in acute and long-term management of hepatic encephalopathy. Treatment of overt hepatic encephalopathy involves management of the acute episode as well as maintenance of remission in those patients who have previously experienced an episode, in order to improve their quality of life. The positive effect of rifaximin in reducing health care costs is also discussed. PMID:24367227

    Twelve mongrel dogs were randomly allocated into two groups using matched paired-design. Catheters were inserted into the hepatic artery, hepatic vein and the femoral vein, respectively. In the first group, gelfoam supplemented with mitomycin C (MMC) was injected into the hepatic artery, whereas the second group received a hepatic arterial injection of MMC solution alone. Simultaneous blood sampling from the hepatic and femoral veins at regular intervals was performed. MMC concentrations in plasma was determined using high performance liquid chromatography (HPLC) and the pharmacokinetics of MMC were determined. MMC concentrations in hepatic and femoral veins did not differ and no significant difference in pharmacokinetics was found when comparing MMC administration into the hepatic artery with or without gelfoam supplementation. Thus, our results revealed that gelfoam could not delay the clearance of MMC from the liver. PMID:1510890

    Metabolic disturbances of bone are frequent in patients with chronic liver disease. The prevalence of osteoporosis among patients with advanced chronic liver disease is reported between 12% and 55%; it is higher in primary biliary cirrhosis. All patients with advanced liver disease should be screened for osteoporosis with a densitometry, especially if the etiology is cholestatic and in the presence of other risk factors. Clinical relevance of hepatic osteodystrophy increases after liver transplantation. After liver transplant, a rapid loss of bone mineral density can be detected in the first 6 months, followed by stabilization and slight improvement of the values. At the time of transplantation, bone density values are very important prognostic factors. Therapy of hepatic osteodystrophy is based primarily on the control of risk factors: cessation of tobacco and alcohol assumption, reduction of caffeine ingestion, exercise, supplementation of calcium and vitamin D, limitation of drugs such as loop diuretics, corticosteroids, cholestyramine. Bisphosphonates have been proposed for the therapy of osteoporosis in patients with liver disease, particularly after liver transplantation. The possible side effects of oral administration of bisphosphonates, such as the occurrence of esophageal ulcerations, are of particular concern in patients with liver cirrhosis and portal hypertension, due to the risk of gastrointestinal hemorrhage from ruptured esophageal varices, although this risk is probably overestimated.

    Hepatic encephalopathy (HE) is a common complication of liver cirrhosis and it can manifest with a broad spectrum of neuropsychiatric abnormalities of varying severity, acuity and time course with important clinical implications. According to recent guidelines, HE has been classified into different types, depending on the severity of hepatic dysfunction, the presence of porto-systemic shunts and the number of previous episodes or persistent manifestations. From a clinical point of view, HE can be recognized as unimpaired, covert (that deals with minimal and grade 1 according to the grading of mental state), and overt (that is categorized from grade 2 to grade 4). Different and only partially known pathogenic mechanisms have been identified, comprising ammonia, inflammatory cytokines, benzodiazepine-like compounds and manganese deposition. Different therapeutic strategies are available for treating HE, in particular the overt HE, since covert HE needs to be managed case by case. Recognition and treatment of precipitating factors represent fundamental part of the management. The more effective treatments, which can be performed separately or combined, are represented by non-absorbable disaccharides (lactulose and lactitol) and the topic antibiotic rifaximin; other possible therapies, mainly used in patients non responders to previous treatments, are represented by branched chain amino acids and metabolic ammonia scavengers.

    In 1997, a random sample of Finnish men (n = 395) and women (n = 393) aged 18-50 years received a postal questionnaire concerning family planning, in which they were asked which contraceptive methods they had ever used and which three methods they considered to be best. Men's contraceptive preferences were compared to those of women. The response rate for men was 45% and for women 56%. The majority of both men and women had used, together with their partners, condom, oral contraceptives (OCs) and intrauterine devices (IUDs). The use of diaphragm, Norplant, Depo Provera and postcoital IUDs was not common. Among the men, 2-11% did not know whether their partner/partners had used the contraceptives in question. Concerning the three best contraceptive methods, men placed the condom first and women OCs. No male or female respondents rated postcoital emergency pills a superior method. Both men and women appreciated the most reliable means. PMID:11145377

    Hepatitis B is a major public health problem even though safe and effective vaccines have been available for over 10 years. Because hepatitis B infection is largely asymptomatic with long term complications occurring after many years it has not received the attention it deserves. Strategies to immunise those at high risk have failed to control the disease. Delegates to the World Health Assembly of the World Health Organisation recommended in May 1992 that all countries should integrate hepatitis B vaccination into their national immunisation programmes by 1997. Some western European countries remain unconvinced that the burden of disease warrants the expense of universal vaccination. However, epidemiological data and economic evaluation show that universal hepatitis B vaccination is cost effective in countries with low endemicity and that it will control hepatitis B, reinforcing the necessity for action.

    2008-01-01

    With the aging of the population, there is a growing recognition that osteoporosis and fractures in men are a significant public health problem, and both hip and vertebral fractures are associated with increased morbidity and mortality in men. Osteoporosis in men is a heterogeneous clinical entity: whereas most men experience bone loss with aging, some men develop osteoporosis at a relatively young age, often for unexplained reasons (idiopathic osteoporosis). Declining sex steroid levels and other hormonal changes likely contribute to age-related bone loss, as do impairments in osteoblast number and/or activity. Secondary causes of osteoporosis also play a significant role in pathogenesis. Although there is ongoing controversy regarding whether osteoporosis in men should be diagnosed based on female- or male-specific reference ranges (because some evidence indicates that the risk of fracture is similar in women and men for a given level of bone mineral density), a diagnosis of osteoporosis in men is generally made based on male-specific reference ranges. Treatment consists both of nonpharmacological (lifestyle factors, calcium and vitamin D supplementation) and pharmacological (most commonly bisphosphonates or PTH) approaches, with efficacy similar to that seen in women. Increasing awareness of osteoporosis in men among physicians and the lay public is critical for the prevention of fractures in our aging male population. PMID:18451258

    Viral hepatitis is a cause for major health care burden in India and is now equated as a threat comparable to the "big three" communicable diseases - HIV/AIDS, malaria and tuberculosis. Hepatitis A virus and Hepatitis E virus are predominantly enterically transmitted pathogens and are responsible to cause both sporadic infections and epidemics of acute viral hepatitis. Hepatitis B virus and Hepatitis C virus are predominantly spread via parenteral route and are notorious to cause chronic hepatitis which can lead to grave complications including cirrhosis of liver and hepatocellular carcinoma. Around 400 million people all over the world suffer from chronic hepatitis and the Asia-Pacific region constitutes the epicentre of this epidemic. The present article would aim to cover the basic virologic aspects of these viruses and highlight the present scenario of viral hepatitis in India. PMID:27546957

    Objective: Chronic infection of hepatitis B and hepatitis C are considered as the most important infectious diseases, which lead to drastic consequences such as liver dysfunction. Depression is a psychiatric disorder which is concomitantly present in these patients, and decreases the patients’ quality of life. It may lead to suicide, homicide or intentional transmission of infectious to others. Medical treatment with interferon can also lead to depression which is comparable to the depression caused by disease. Methods: We performed a cross sectional study on 205 patients with hepatitis B and hepatitis C infection. We aimed to determine the prevalence of depression via Beck Depression Inventory (BDI), and its correlates with hepatitis drugs. Results: Of 205 patients, 154 cases had hepatitis B and 51 cases had hepatitis C infection. The frequency of depression was 68% in hepatitis B and 86% in hepatitis C infected patients (p<0.05). The frequency of mild depression was 14%, moderate depression was 57.3% and severe depression was 28.7% (p<0.05). Depression frequency in Interferon recipients was 100%, in interferon-ribavirin recipients was 94.4%, in lamivudine recipients was 64%, and in patients that receive no drug was 66.7%. Depression prevalence was significantly higher among those on interferon therapy (p<0.05). Conclusion: There is a high prevalence of depression among patients with hepatitis B and hepatitis C infection, especially patients on interferon therapy. Hence these patients should be repeatedly evaluated for depression. Declaration of Interest: None. PMID:24644496

    The demand for topical products capable of preventing aging or delivering cosmetic improvement to the male skin is growing. Companies are marketing products that are labeled "for men." Nevertheless, there is no consensus on which properties these products should possess. This article aims to develop a rational approach to men's cosmeceuticals based on anatomic and physiologic features of the male skin without neglecting behavioral idiosyncrasies when relevant. A review of the literature for skin gender singularities was used to determine the needs of male skin and subsequently to postulate how cosmeceuticals could fulfill these needs. Cosmeceutical ingredients capable of reversing sun-induced alteration are of particular benefit for men. Adapting cosmetic treatment to male grooming routines increases compliance. Shaving presents an opportunity to deliver cosmeceuticals for men. The marketing of skin care products for men is evolving and becoming seemingly complex; further research is warranted.

    Athletic activities are associated with reduced levels of stress and negative mood states among heterosexuals; thus, examining this association among gay/bisexual men is warranted. The current study examined the relationship between sports motivation and mood states, self-esteem, body esteem, life satisfaction, perceptions of masculinity/femininity, and parental encouragement for athletic endeavors among 195 gay/bisexual men. The results were mixed, but suggest that sports participation among gay/bisexual men may relate to a desire to express their masculinity and maintain a positive body image. Gay/bisexual men may be more likely to participate in sports if they receive positive reinforcement from others. PMID:18826171

  16. Linking men to family planning services.

    PubMed

    1999-02-01

    The US Office of Family Planning (FP) has issued 10 research grants ranging from $100,000 to $250,000 to organizations seeking to develop, implement, and test ways to involve young men in FP and reproductive health services. While only 2% of federal dollars are currently earmarked for reproductive health services for young men, a survey revealed that only 32% of sexually active men and 17% of sexually inexperienced men reported receiving contraceptive information from health care providers. One grant recipient is a cooperative venture of the University of North Carolina, the Guilford County health department, and "Wise Guys," a male responsibility/adolescent pregnancy prevention program developed by the local Family Life Council in 1989 that focuses on seventh-grade boys. The grant allowed Wise Guys to add a peer education component and hire the first male health educator in the county health department. This educator notes that the biggest misconceptions held by young men about the health department are that test results are shared with parents, that the agency serves only impoverished people, and that every client must be tested for pregnancy or sexually transmitted diseases (STDs). The health educator addresses these misconceptions in classes and individual counseling sessions, and he accompanies young men to STD tests. PMID:12294592

  17. [Viral hepatitis in travellers].

    PubMed

    Abreu, Cândida

    2007-01-01

    Considering the geographical asymmetric distribution of viral hepatitis A, B and E, having a much higher prevalence in the less developed world, travellers from developed countries are exposed to a considerable and often underestimated risk of hepatitis infection. In fact a significant percentage of viral hepatitis occurring in developed countries is travel related. This results from globalization and increased mobility from tourism, international work, humanitarian and religious missions or other travel related activities. Several studies published in Europe and North America shown that more than 50% of reported cases of hepatitis A are travel related. On the other hand frequent outbreaks of hepatitis A and E in specific geographic areas raise the risk of infection in these restricted zones and that should be clearly identified. Selected aspects related with the distribution of hepatitis A, B and E are reviewed, particularly the situation in Portugal according to the published studies, as well as relevant clinical manifestations and differential diagnosis of viral hepatitis. Basic prevention rules considering enteric transmitted hepatitis (hepatitis A and hepatitis E) and parenteral transmitted (hepatitis B) are reviewed as well as hepatitis A and B immunoprophylaxis. Common clinical situations and daily practice "pre travel" advice issues are discussed according to WHO/CDC recommendations and the Portuguese National Vaccination Program. Implications from near future availability of a hepatitis E vaccine, a currently in phase 2 trial, are highlighted. Potential indications for travellers to endemic countries like India, Nepal and some regions of China, where up to 30% of sporadic cases of acute viral hepatitis are caused by hepatitis E virus, are considered. Continued epidemiological surveillance for viral hepatitis is essential to recognize and control possible outbreaks, but also to identify new viral hepatitis agents that may emerge as important global health

    2013-05-01

    With the decrease in transmission via transfusions and injection drug use, acute symptomatic hepatitis C is infrequently seen in developed countries. We report a case of a human immunodeficiency virus (HIV)-infected adult who presented with abdominal pain. His alanine aminotransferase was greater than sixty times the upper limit of normal without any evidence on examination of fulminant hepatic failure. His workup revealed an elevated hepatitis C viral level with a negative hepatitis C antibody. He was discharged once his liver function tests improved. As an outpatient, he had a recurrent bout of symptoms with an elevation of his alanine aminotransferase and hepatitis C viral levels that promoted anti-hepatitis C virus treatment. This case illustrates the importance of considering acute hepatitis C as a cause of acute hepatitis in HIV-infected men who have sex with men. While patients with acute symptomatic hepatitis C generally have a higher rate of spontaneous viral clearance compared to those with an insidious acute infection, most still progress to chronic hepatitis C infection, and patients with HIV coinfection carry a higher risk of progression to chronic disease.

    Objectives Chronic hepatitis C (CHC) is a major public health problem in Puerto Rico. It is the most common cause of chronic liver disease and the most frequent indication for liver transplantation in the United States." Our main objectives were to estimate the seroprevalence of CHC infection, to describe the demographic and histological parameters of the infection in our sample population, and to evaluate the treatment outcomes in Puerto Rican veterans. Methods To determine overall seroprevalence, we reviewed all the hepatitis C cases (encompassing from January 1, 2002, to December 31, 2009) of the VA Caribbean Healthcare System, Department of Veterans Affairs. The records of only those individuals who received treatment with pegylated interferon and ribavirin were reviewed to determine risks factors for infection, response rates, adverse events, and outcomes. Results During the study period, there were a total of 1,496 patients identified as being infected with HCV, for an estimated seroprevalence of 2.3%. Of these, approximately 10% (137) were treated with combination therapy and were included in this study. The mean age was 58 (±6.4); 96.4% were men. The most common genotype was type 1. The responses to treatment were generally poor, with only 48.4% of the patients achieving Ssustained virological response. Discussion Though the seroprevalence of chronic hepatitis C in the Latino veteran population of Puerto Rico is high, relatively few patients have received treatment, most probably because of the contraindications of the medications used. Combination therapy with pegylated interferon plus weight-based ribavirin was inefficient and plagued with side effects; as a whole, this therapy was not found to be overly beneficial to our patients. New emerging and approved therapies will change this paradigm, allowing the treatment of a larger population without the side effects of the studied therapy. PMID:26932282

    Hepatic abscesses are potentially lethal diseases if early diagnosis and treatment are not instituted. They are prevalent all over the globe and pyogenic abscesses are predominant over amoebic. With better control of intra abdominal and systemic infections by a spectrum of antibiotics, aetiology of pyogenic abscesses are secondary to interventions and diseases in the biliary tree to a large extent today. The common organisms isolated are the Gram negative group. Amoebic abscesses continue to plague some regions of the world where hygiene and sanitation are questionable. Over the years, diagnosis, treatment and prognosis have evolved remarkably. Imaging modalities like ultrasonography and CT scan have become the cornerstone of diagnosis. The absence of ionizing radiation makes MRI an attractive alternative in patients who require multiple follow up scans. Serological testing in amoebic abscesses has become more reliable. Though antibiotics have remained the principal modality of management, percutaneous drainage of abscesses have vastly improved the chances of cure and bring down the morbidity drastically in pyogenic abscesses. Amoebic abscesses respond well to medical treatment with nitroimidazoles, and minimally invasive surgical drainage is an option in cases where open surgery is indicated. PMID:24532886

    The seroepidemiology of hepatitis B was studied in Kiribati (formerly the Gilbert Islands). Six hundred and two (98%) of the population studied showed evidence of current or previous infection. The prevalence of hepatitis B surface antigen was 31% (188/615) and of the e antigen was 9% (58/615). Infection was acquired early in life, and the prevalence of both antigens declined with age. The rates of infection were similar in all age groups examined (0-70) including early childhood. Both hepatitis B surface antigen and e antigen were detected in exudates from tropical ulcers, which may be a source of environmental hepatitis B. Concordance of antigen presence was higher in pairs of siblings than in mother-child pairs. All Gilbertese children should receive hepatitis B vaccine at birth or soon after if the long term consequences of hepatitis B infection are to be minimised. PMID:3103763

    Background & Aims In the Netherlands, a selective hepatitis B virus (HBV) vaccination programme started in 2002 for men having sex with men, drug users, commercial sex workers and heterosexuals with frequent partner changes. We assessed the programme's effectiveness to guide policy on HBV prevention. Methods We analysed reports of acute HBV infection in the Netherlands between 2004 and 2010 requesting serum from patients for HBV-genome S- and C-region sequencing. We used coalescence analyses to assess genetic diversity of nonimported genotype-A cases over time. Results 1687 patients with acute HBV infection were reported between 2004 and 2010. The incidence of reported acute HBV infection decreased from 1.8 to 1.2 per 100,000 inhabitants, mostly due to a reduction in the number of cases in men who have sex with men. Men were overrepresented among cases with an unknown route of transmission, especially among genotype A2 cases mainly associated with transmission through male homosexual contact. The genetic diversity of nonimported genotype-A strains obtained from men who have sex with men decreased from 2006 onwards, suggesting HBV incidence in this group decreased. Conclusions The selective HBV-vaccination programme for behavioural high-risk groups very likely reduced the incidence of HBV infection in the Netherlands mainly by preventing HBV infections in men who have sex with men. A considerable proportion of cases in men who did not report risk behaviour was probably acquired through homosexual contact. Our findings support continuation of the programme, and adopting similar approaches in other countries where HBV transmission is focused in high-risk adults. PMID:23922651

    Background The psychological wellbeing of people with chronic hepatitis B (CHB) may be negatively affected due to the chronic and transmissible nature of the disease, and possible serious complications (e.g. cirrhosis and liver cancer). There are limited data investigating concerns and anxieties among people living with CHB. Objectives This study examined feelings about having hepatitis B among people with CHB, including hepatitis B-related concerns and anxieties. Patients and Methods Using convenience sampling, people with CHB attending four public liver clinics and one general practice in three Australian jurisdictions between April and September 2013 completed a self-administered questionnaire about their feelings about having hepatitis B. Results Ninety-three people completed the survey. Mean age was 45 years, 57% were men, and 93% were born overseas (75% from Asia). Seventy-six percent of participants reported having hepatitis B-related concerns and anxieties. The most common concerns were of developing liver cancer (57%), and infecting other people (53%). Thirty-five percent of participants were unwilling to talk to anyone about their hepatitis B while 25% changed how they lived as a result of having hepatitis B. Lower educational level was associated with feeling scared of hepatitis B (adjusted Odds Ratio [OR]: 4.04; 95%CI: 1.09, 14.90; P = 0.04), and an unwillingness to talk to anyone about hepatitis B (adjusted OR: 4.41; 95%CI: 1.09, 17.83; P = 0.04). Very good English proficiency was associated with a higher likelihood of participants changing how they lived (adjusted OR: 12.66; 95%CI: 2.21, 72.42; P < 0.01), and seeing life differently as a result of having hepatitis B (adjusted OR: 21.10; 95%CI: 3.70, 120.19; P < 0.01). Health professionals were the key person for 34% of participants in helping them cope with having hepatitis B, while 18% reported that no one supported them. Conclusions Hepatitis B-related concerns and anxieties are prevalent among

    Hepatitis B virus (HBV) and hepatitis C virus (HCV), discovered as causative viruses of post-transfusion hepatitis, become persistent infections, leading to chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). For HCV, recent IFN-free direct-acting antiviral (DAA) therapies have increased sustained virological response (SVR) rates and reduced adverse events. IFN-based therapies, still the standard of care in Asian countries, are influenced by IL28B genetic variants and the liver fibrosis stage, but the DAA combinations obscure the influence of these factors. These new therapies can eradicate HCV and prevent HCC development. On the other hand, it is difficult to eradicate HBV completely. Although HBV infection can be prevented by vaccination, reactivation of HBV following anti-cancer chemotherapy and immunosuppressive therapy is a well-known complication. HBV reactivation has been reported to be associated with anti-CD20 monoclonal antibody rituximab-containing chemotherapy and TNF-α inhibitor-containing immunosuppressive therapy in HBV-resolved patients. Our prospective observational study revealed that monthly monitoring of HBV DNA was useful for preventing HBV reactivation-related hepatitis among B-cell non-Hodgkin lymphoma patients with resolved HBV infection following rituximab-steroid-chemo, suggesting that preemptive therapy guided by serial HBV DNA monitoring should be recommended. Recently, highly sensitive HBsAg detection by Lumipulse HBsAg-HQ may be useful for several clinical applications. The sensitivity of this assay (5 mIU/mL) was approximately 10-fold higher than Abbott ARCHITECT, but still lower than HBV-DNA assays. The convenient HBsAg-HQ may be useful for detecting occult HBV infection and HBV reactivation in relatively low-risk groups except for those receiving rituximab-steroid-chemo. [ PMID:27311286

    ABSTRACT Objective: To characterize a chronic hepatitis B cohort based on initial and follow-up clinical evaluations. Methods: A retrospective and descriptive analysis of clinical and laboratory data from chronic HBsAg adult carriers, without HIV, unexposed to treatment, with at least two outpatient visits, between February 2006 and November 2012. Fisher´s exact test, χ², Wilcoxon, Spearman, multiple comparisons and Kappa tests were applied, the level of significance adopted was 5%, with a 95% confidence interval. Results: 175 patients with mean age of 42.95±12.53 years were included: 93 (53.1%) were men, 152 (86.9%) were negative for hepatitis B e-antigen (HBeAg), 3 (1.7%) had hepatitis C coinfection, 15 (8.6%) had cirrhosis, and 2 (1.1%) had hepatocellular carcinoma. Genotype A predominated. Sixty-six patients (37.7%) had active hepatitis, 6 (3.4%) presented immune tolerance, and 38 (21.7%) were inactive carriers. Exacerbations and/or viral breakthrough were detected in 16 patients (9.1%). In 32 patients (18.3%), hepatitis B virus DNA remained persistently elevated and alanine aminotransferase levels were normal, whereas in 17 (9.7%), there was low hepatitis B virus DNA and alterated alanine aminotransferase. If only initial alanine aminotransferase and hepatitis B virus DNA values were considered, 15 cases of active hepatitis would not have been detected. Advanced fibrosis was more common in HBeAg-positive patients, and it was significantly associated with transaminases, hepatitis B virus DNA, and age. Conclusion: Many patients had active hepatitis, but almost 25%, who were HBeAg non-reactive, were only identified because of combined analyses of the hepatitis B virus DNA and transaminases levels, sometimes associated with histological data, after clinical follow-up.

    Background & Aims Hepatitis B virus (HBV) infection may reactivate in the setting of immune suppression, although the frequency and consequences of HBV reactivation are not well known. We report six patients who experienced loss of serologic markers of hepatitis B immunity and reappearance of Hepatitis B surface antigen (HBsAg) in the serum due to a variety of acquired immune deficiencies. Methods Between 2000 and 2005, six patients with reactivation of hepatitis B were seen in consultation by the Liver Diseases Branch at the Clinical Center, National Institutes of Health. The course and outcome of these six patients were reviewed. Results All six patients developed reappearance of HBsAg and evidence of active liver disease after stem cell transplantation (n=4), immunosuppressive therapy (n=1) or change in HIV antiretroviral regimen (n=1) despite having antibody to HBsAg (anti-HBs) or antibody to hepatitis B core antigen (anti-HBc) without HBsAg before. All six patients developed chronic hepatitis B, two patients transmitted hepatitis B to their spouses, and one patient developed cirrhosis. The diagnosis of hepatitis B reactivation was frequently missed or delayed and often required interruption of the therapy for the underlying condition. None of the patients received antiviral prophylaxis against HBV reactivation. Conclusions Serologic evidence of recovery from hepatitis B infection does not preclude its reactivation after immunosuppression. Screening for serologic evidence of hepatitis B and prophylaxis of those with positive results using nucleoside analogue antiviral therapy should be provided to individuals in whom immunosuppressive therapy is planned.

    Many new and existing cases of viral hepatitis infections are related to injection drug use. Transmission of these infections can result directly from the use of injection equipment that is contaminated with blood containing the hepatitis B or C virus or through sexual contact with an infected individual. In the latter case, drug use can indirectly contribute to hepatitis transmission through the dis-inhibited at-risk behavior, that is, unprotected sex with an infected partner. Individuals who inject drugs are at-risk for infection from different hepatitis viruses, hepatitis A, B, or C. Those with chronic hepatitis B virus infection also face additional risk should they become co-infected with hepatitis D virus. Protection from the transmission of hepatitis viruses A and B is best achieved by vaccination. For those with a history of or who currently inject drugs, the medical management of viral hepatitis infection comprising screening, testing, counseling and providing care and treatment is evolving. Components of the medical management of hepatitis infection, for persons considering, initiating, or receiving pharmacologic therapy for opioid addiction include: testing for hepatitis B and C infections; education and counseling regarding at-risk behavior and hepatitis transmission, acute and chronic hepatitis infection, liver disease and its care and treatment; vaccination against hepatitis A and B infection; and integrative primary care as part of the comprehensive treatment approach for recovery from opioid abuse and dependence. In addition, participation in a peer support group as part of integrated medical care enhances treatment outcomes. Liver disease is highly prevalent in patient populations seeking recovery from opioid addiction or who are currently receiving pharmacotherapy for opioid addiction. Pharmacotherapy for opioid addiction is not a contraindication to evaluation, care, or treatment of liver disease due to hepatitis virus infection. Successful

    Men who have sex with men (MSM) in Baltimore are at disproportionately high risk for HIV and syphilis infection. Testing and diagnosis are important first steps in receiving treatment and reducing transmission. We analyzed cross-sectional data collected in 2004-2005, 2008, and 2011 among MSM not reporting a previous positive HIV test (n = 1268) in Baltimore, Maryland as part of the National HIV Behavioral Surveillance System to determine the proportion of men tested for HIV and/or syphilis within the previous 12 months and examine the extent to which opportunities for testing were being missed in health care settings. Within the previous 12 months, 54 % of men had received an HIV test; 31 % had received a syphilis test; and only 23 % of men had received testing for both. Among 979 men who did not receive both tests, 72 % had seen a health care provider in the past year, suggesting missed testing opportunities. PMID:26078117

    Increasing numbers of HIV-serodiscordant heterosexual couples are concerned about the chances for pregnancy. We reviewed all natural pregnancies attained by HIV-serodiscordant couples seen in 3 clinics in Spain, in which the infected partner had undetectable plasma viremia while receiving highly active antiretroviral therapy (HAART). In the case of HIV-infected mothers, only those with undetectable viremia during pregnancy and at delivery were chosen. A total of 62 HIV-serodiscordant couples, 22 HIV-infected women (mean CD4 count of 522 cells/microL, 55% hepatitis C virus [HCV]-seropositive) and 40 HIV-infected men (mean CD4 count of 629 cells/microL, 75% HCV-seropositive), were recorded. Overall, 76 natural pregnancies occurred, and 68 children were born. There were 9 fetal deaths, 1 twin pregnancy, 6 couples with 2 consecutive babies, and 4 couples with 3 consecutive newborns. There were no cases of HIV seroconversion in uninfected sexual partners. One case of vertical HIV transmission occurred, however. Serodiscordant couples attaining natural pregnancy are exposed to a negligible risk of sexual transmission of HIV when the infected partner presents with complete suppression of plasma viremia while receiving HAART.

    2015-01-01

    Hepatitis B virus is a worldwide leading cause of acute and chronic liver disease including cirrhosis and hepatocellular carcinoma. Effective vaccines have been available since the early '80s and vaccination has proved highly successful in reducing the disease burden, the development of the carrier state and the HB-related morbidity and mortality in the countries where vaccination has been implemented.   Neutralizing (protective) antibodies (anti-HBs) induced by vaccination are targeted largely towards the amino acid hydrophilic region, referred to as the common a determinant which is present on the outer protein coat or surface antigen (HBsAg), spanning amino acids 124-149. This provides protection against all HBV genotypes (from A to H) and is responsible for the broad immunity afforded by hepatitis B vaccination. Thus, alterations of residues within this region of the surface antigen may determine conformational changes that can allow replication of the mutated HBV in vaccinated people. An important mutation in the surface antigen region was identified in Italy some 25 years ago in infants born to HBsAg carrier mothers who developed breakthrough infections despite having received HBIG and vaccine at birth. This virus had a point mutation from guanosine to adenosine at nucleotide position 587, resulting in aa substitution from glycine (G) to arginine (R) at position 145 in the a determinant. Since the G145R substitution alters the projecting loop (aa 139-147) of the a determinant, the neutralizing antibodies induced by vaccination are no longer able to recognize the mutated epitope. Beside G145R, other S-gene mutations potentially able to evade neutralizing anti-HBs and infect vaccinated people have been described worldwide. In addition, the emergence of Pol mutants associated with resistance to treatment with nucleos(t)ide analogues can select viruses with crucial changes in the overlapping S-gene, potentially able to alter the S protein immunoreactivity.

    The underlying principles of operation of microwave receivers for space observations of planetary surfaces were examined. The design philosophy of the receiver as it is applied to operate functionally as an efficient receiving system, the principle of operation of the key components of the receiver, and the important differences among receiver types are explained. The operating performance and the sensitivity expectations for both the modulated and total power receiver configurations are outlined. The expressions are derived from first principles and are developed through the important intermediate stages to form practicle and easily applied equations. The transfer of thermodynamic energy from point to point within the receiver is illustrated. The language of microwave receivers is applied statistics.

  10. Attracting men to vasectomy.

    PubMed

    Finger, W R

    1998-01-01

    There is far less information available for men about vasectomy than there is available for women about comparable contraceptive services. Also, men do not have medical check-ups on a regular basis, and therefore have less contact with medical practitioners during which vasectomy could otherwise be discussed. Vasectomy needs to be promoted in order for men to learn about and accept it as their contraceptive method of choice. To that end, Marie Stopes International (MSI) launches a vasectomy promotion campaign annually which includes advertising in local newspapers and upon billboards at football stadiums. The campaigns use light-hearted and bold ideas, with some shock value. This approach helps to relax men who otherwise tend to be wary of both the surgical procedure and subsequent consequences of vasectomy. Prevailing social norms should, however, guide the content of promotional campaigns. The UK is one of only a few countries in the world where about the same proportions of men and women use sterilization; 16% of men and 15% of women have been sterilized. A MSI campaign in the UK which began during fall 1997 prompted an increase in the number of inquiries about vasectomy at the Marie Stopes Vasectomy Clinic. Promotional campaigns in developing countries have also been successful. It is also important that campaigns be put in the larger context of promoting all contraceptive methods. PMID:12293534

    Burn injury causes hepatic dysfunction associated with endoplasmic reticulum (ER) stress and induction of the unfolded protein response (UPR). ER stress/UPR leads to hepatic apoptosis and activation of the Jun-N-terminal kinase (JNK) signaling pathway, leading to vast metabolic alterations. Insulin has been shown to attenuate hepatic damage and to improve liver function. We therefore hypothesized that insulin administration exerts its effects by attenuating postburn hepatic ER stress and subsequent apoptosis. Male Sprague Dawley rats received a 60% total body surface area (TBSA) burn injury. Animals were randomized to receive saline (controls) or insulin (2.5 IU/kg q. 24 h) and euthanized at 24 and 48 h postburn. Burn injury induced dramatic changes in liver structure and function, including induction of the ER stress response, mitochondrial dysfunction, hepatocyte apoptosis, and up-regulation of inflammatory mediators. Insulin decreased hepatocyte caspase-3 activation and apoptosis significantly at 24 and 48 h postburn. Furthermore, insulin administration decreased ER stress significantly and reversed structural and functional changes in hepatocyte mitochondria. Finally, insulin attenuated the expression of inflammatory mediators IL-6, MCP-1, and CINC-1. Insulin alleviates burn-induced ER stress, hepatocyte apoptosis, mitochondrial abnormalities, and inflammation leading to improved hepatic structure and function significantly. These results support the use of insulin therapy after traumatic injury to improve patient outcomes. PMID:21267509

    A receiver is described for converting solar energy to heat a gas to temperatures from 700 to 900/sup 0/C. The receiver is formed to minimize impingement of radiation on the walls and to provide maximum heating at and near the entry of the gas exit. Also, the receiver is formed to provide controlled movement of the gas to be heated to minimize wall temperatures. The receiver is designed for use with gas containing fine heat absorbing particles, such as carbon particles.

    Hepatic encephalopathy can be a serious complication of acute liver failure and chronic liver diseases, predominantly liver cirrhosis. Hyperammonemia plays the most important role in the pathogenesis of hepatic encephalopathy. The brain-blood barrier disturbances, changes in neurotransmission, neuroinflammation, oxidative stress, GABA-ergic or benzodiazepine pathway abnormalities, manganese neurotoxicity, brain energetic disturbances, and brain blood flow abnormalities are considered to be involved in the development of hepatic encephalopathy. The influence of small intestine bacterial overgrowth (SIBO) on the induction of minimal hepatic encephalopathy is recently emphasized. The aim of this paper is to present the current views on the pathogenesis of hepatic encephalopathy. PMID:23316223

    Hepatitis is the primary occupational hazard for healthcare workers. Not until the 1970s were hepatitis viruses isolated and identified as types A and B. In the late 1970s, hepatitis D was discovered as a major cause of fulminant hepatitis. Soon, it was evident that another type was also at work. Because testing was only available for types A and B, the new category was referred to as non-A, non-B. In the 1980s, scientists identified two more viruses from this non-A, non-B group, namely hepatitis E and hepatitis C. These five types of hepatitis have different modes of transmission. The fecal-to-oral route is the mode of transmission for hepatitis types A and E. But, types B and D are bloodborne pathogens. With the advent of a safe vaccine for hepatitis B, this category is declining. To date, hepatitis C appears to have multiple routes of transmission, with half the cases being posttransfusion. In the United States, 85,000 people per year develop chronic hepatitis C, which ultimately leads to severe liver damage. This paper addresses each of the five viruses that have been grouped by routes of transmission, prevention techniques for BMETs and CEs, and statistics of reported cases to the Centers for Disease Control and Prevention (CDCP) over the last 20 years.

    Surveys were conducted to determine the occurrence of overt hepatitis manifested by jaundice in groups of hospital patients who had survived their initial illness. Of those who had been given blood that had not been screened for the presence of hepatitis B antigen (HB Ag) 9.4% reported that they had had jaundice during the 6 months following transfusion. During a similar period jaundice was reported by only 1.1% of those who had received blood found to be negative for HB Ag by the cross-over electrophoresis test. This difference is highly significant. Jaundice was reported by 25.5% of recipients of HB Ag-positive blood. Of a control population of hospitalized but non-transfused patients 2.2% reported jaundice within 6 months of hospitalization. The risk of overt hepatitis from HB Ag in transfused blood is high in southern India and is similar to that in temperate countries where the occurrence of antigen carriers, and presumably of immune status, are lower than in the tropics.

  18. Why men violate.

    PubMed

    Mcfadden, P

    1993-10-01

    Soldiers in Bosnia-Herzegovina freely rape and kill women. In Botswana, a policeman laughed when a mother reported the rape of her daughter; he commented that some men are fortunate and do not have to pay for sex. His behavior condoned rape as men's right to any female they want. Girls are the most vulnerable of all females. In South Africa, white adults claim that black men and women spread HIV, yet white policemen and white soldiers have raped many black women. White bosses often rape their black housekeepers. A rapist is defined an any man who believes he has the right to rape a woman or child to express his patriarchal sexual power. Most rapists in Africa are black men. Yet many adults continue to deny that male Africans rape and molest children, explaining in part why rape of children and married women is still a silent problem. A study in Zimbabwe shows that the numbers of children less than 11 years old who are raped is increasing quickly (in 1993, 56 of 57 children were girls). Men tend to rape women whom they know, who are often female family members. Men in all classes violate women with whom they work. Rarely do women place themselves in danger. Marital rape is no uncommon, but is often ignored. Society tends to blame the victim, even when she is a child. Same-sex rape does occur, but is rare, and often occurs in prisons. Soldiers, especially during war, believe that women have no value. Men from both sides always consider women to be the enemy. Instead of being captured and shot, women are raped and desecrated as human beings. Often soldiers have no identity outside of their military uniform, and that identity is limited to taking orders, so they assume power over unarmed, defenseless women. PMID:12287226

    2003-01-01

    Hepatic encephalopathy (HE) is a complication that presents in as many as 28% of patients with cirrhosis, and reported up to ten years after the diagnosis of cirrhosis. Commonly, it is observed in patients with severe hepatic failure and is characterized by neuropsychiatric manifestations that can range in severity from a mild alteration in mental state to a coma; additionally, some neuromuscular symptoms can be observed. This complication of either acute or chronic hepatic disease is the result of a diminished hepatic reservoir and inability to detoxify some toxins that originate in the bowel. Today, the role of astrocytes, specifically the Alzheimer type II cells, is known to be very important in the pathogenesis of the hepatic encephalopathy, and will be reviewed later. In conclusion, the objectives of this review are: To understand the pathogenesis of hepatic encephalopathy, To recognize the precipitating factors, as well as preventive measures for the development of the hepatic encephalopathy, To describe the new classification of hepatic encephalopathy and its clinical implications, To recognize the clinical manifestations and stages of the disease, To understand the main diagnostic tests used to detect the hepatic encephalopathy, To describe the main therapeutic treatments of hepatic encephalopathy.

    The gender paradox in mortality--where men die earlier than women despite having more socioeconomic resources--may be partly explained by men's lower levels of preventive health care. Stereotypical notions of masculinity reduce preventive health care; however, the relationship between masculinity, socioeconomic status (SES), and preventive health care is unknown. Using the Wisconsin Longitudinal Study, the authors conduct a population-based assessment of masculinity beliefs and preventive health care, including whether these relationships vary by SES. The results show that men with strong masculinity beliefs are half as likely as men with more moderate masculinity beliefs to receive preventive care. Furthermore, in contrast to the well-established SES gradient in health, men with strong masculinity beliefs do not benefit from higher education and their probability of obtaining preventive health care decreases as their occupational status, wealth, and/or income increases. Masculinity may be a partial explanation for the paradox of men's lower life expectancy, despite their higher SES. PMID:21490311

    Prostate cancer incidence and mortality are highest among African-American men, and coupled with the controversy around routine prostate cancer screening, reaching African-American men with interventions to help them make an informed decision about whether or not to be screened is critical. This study compares two approaches to delivering a church-based peer community health advisor intervention consisting of a series of four men's health workshops on informed decision-making for prostate cancer screening. In the men-only group, male community health advisors teach group workshops consisting only of men. In the health partner group, male-female pairs of community health advisors teach workshops in a mixed-gender format in which enrolled men are asked to invite a significant woman in their lives (e.g., wife/partner, sister, daughter, friend) with them to the workshops. Eighteen African-American churches were randomized to receive one of the two approaches, and 283 eligible men enrolled in the intervention. Main findings suggested that the workshops had an impact on stage of decision-making, and this increased significantly over time in the health partner group only. The intervention was highly rated by men in both groups, and these ratings increased over time, with some study group differences. Within-workshop study group differences favored the health partner group in some instances; however, men in the men-only groups reported greater increases in their ratings of trust in the workshops over time. The health partner intervention strategy appears to be promising for reaching men of color with health information. PMID:25330866

    There is a notable dearth of data about Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) prevalence in Afghanistan. Awareness program and research capacity in the field of hepatitis are very limited in Afghanistan. Number of vulnerabilities and patterns of risk behaviors signal the need to take action now. Thirty one studies dating from October 2003 to 2011 were included, consisting the data of 132,981 individuals for HBV and 132,500 individuals for HCV. Percentage prevalence was 1.9% for HBV and 1.1% for HCV in all available Afghanistan population. Most at risk population to hepatitis include injecting drug users who share needles and female sex workers, while truck drivers, prisoners and homosexual men needs attention, as their statistical figure are missing. Data suggests that high incidence of intravenous drug use, sexual activities, unsafe blood transfusion procedures and mobility are major risk factors for hepatitis transmission. This review is based on analysis of the limited available data in Afghanistan. Although there are many underlying vulnerability factors, it appears that Afghanistan remains at an early epidemic phase. Further research is required to determine the seroprevalence and prevalent genotype(s) of HBV and HCV in all provinces in Afghanistan. This article provides some key insights into the potential and likely future transmission dynamics of hepatitis which will serve as a guide in the identification of priority areas in term of high risk groups and risk behaviours in the country and will assist to develop urgent strategic plans to combat the future burden of hepatitis in Afghanistan.

    This invention is an ultra-low frequency electromagnetic telemetry receiver which fuses multiple input receive sources to synthesize a decodable message packet from a noise corrupted telemetry message string. Each block of telemetry data to be sent to the surface receiver from a borehole tool is digitally encoded into a data packet prior to transmission. The data packet is modulated onto the ULF EM carrier wave and transmitted from the borehole to the surface and then are simultaneously detected by multiple receive sensors disbursed within the rig environment. The receive sensors include, but are not limited to, electric field and magnetic field sensors. The spacing of the surface receive elements is such that noise generators are unequally coupled to each receive element due to proximity and/or noise generator type (i.e. electric or magnetic field generators). The receiver utilizes a suite of decision metrics to reconstruct the original, non noise-corrupted data packet from the observation matrix via the estimation of individual data frames. The receiver will continue this estimation process until: 1) the message validates, or 2) a preset "confidence threshold" is reached whereby frames within the observation matrix are no longer "trusted".

A total of 334 (88%) answered the questionnaire. In the autumn of 1988, a total of 27 men answered the test questionnaire, while in the spring of 1989, when the real study was conducted, 307 men answered it. The median age of 334 participants was 18 years (range of 17-29 years). 33% of the group stated that they had used condoms during first intercourse, while 47% had not. 1 person reported to be exclusively attracted sexually to men, 5 persons were attracted both to men and women, but 97% were exclusively attracted to women. 82% had had intercourse or other sexual experience with women. 1.8% had had intercourse or other sexual experience with men. 8% had no sexual experience, and 8% did not answer the question. Oral contraceptives were used by 60% and the condom by 56%. 10% had used coitus interruptus at one time or another; 15% had used no contraception; 5% used the IUD; and 5% used the diaphragm. Some gave several answers. 1% used spermicidal lotion. 60% thought that it was the responsibility of both men and women to be concerned about contraception, 12% opined that it was exclusively men's duty, and 2% that it was exclusively women's, while 26% did not answer. 68% wanted to use the condom in the future for protection, 24% did not know, but 8% did not want to use it more extensively. 64% did not think that the fear of AIDS would affect their sexual life, but 36% thought it would. Several of the subjects indicated that they would be more careful about choosing a partner, and every 10th suggested that they would use the condom with a new partner. One person (0.3%) was a drug addict, 89% had never injected drugs, but about 11% did not answer about drugs. 97% and 95%, respectively, indicated that the condom provided good protection against pregnancy and venereal diseases.

    Purpose: To compare subharmonic aided pressure estimation (SHAPE) with pressure catheter–based measurements in human patients with chronic liver disease undergoing transjugular liver biopsy. Materials and Methods: This HIPAA-compliant study had U.S. Food and Drug Administration and institutional review board approval, and written informed consent was obtained from all participants. Forty-five patients completed this study between December 2010 and December 2011. A clinical ultrasonography (US) scanner was modified to obtain SHAPE data. After transjugular liver biopsy with pressure measurements as part of the standard of care, 45 patients received an infusion of a microbubble US contrast agent and saline. During infusion, SHAPE data were collected from a portal and hepatic vein and were compared with invasive measurements. Correlations between data sets were determined by using the Pearson correlation coefficient, and statistical significance between groups was determined by using the Student t test. Results:- The 45 study patients included 27 men and 18 women (age range, 19–71 years; average age, 55.8 years). The SHAPE gradient between the portal and hepatic veins was in good overall agreement with the hepatic venous pressure gradient (HVPG) (R = 0.82). Patients at increased risk for variceal hemorrhage (HVPG ≥ 12 mm Hg) had a significantly higher mean subharmonic gradient than patients with lower HVPGs (1.93 dB ± 0.61 [standard deviation] vs −1.47 dB ± 0.29, P < .001), with a sensitivity of 100% and a specificity of 81%, indicating that SHAPE may be a useful tool for the diagnosis of clinically important portal hypertension. Conclusion: Preliminary results show SHAPE to be an accurate noninvasive technique for estimating portal hypertension. © RSNA, 2013 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.13121769/-/DC1 PMID:23525208

    This paper draws on ethnographic and interview based fieldwork to explore accounts of intimate relationships between widowed women and poor young men that emerged in the wake of economic crisis and a devastating HIV epidemic among the Luo ethnic group in Western Kenya. I show how the cooptation of widow inheritance practices in the wake of an overwhelming number of widows as well as economic crisis resulted in widows becoming providing women and poor young men becoming kept men. I illustrate how widows in this setting, by performing a set of practices central to what it meant to be a man in this society – pursuing and providing for their partners - were effectively doing masculinity. I will also show how young men, rather than being feminized by being kept, deployed other sets of practices to prove their masculinity and live in a manner congruent with cultural ideals. I argue that ultimately, women’s practice of masculinity in large part seemed to serve patriarchal ends. It not only facilitated the fulfillment of patriarchal expectations of femininity – to being inherited – but also served, in the end, to provide a material base for young men’s deployment of legitimizing and culturally valued sets of masculine practice.

    Eleven patients (nine men, one woman, and one girl) aged 11-62 years who developed diabetes mellitus after an attack of infectious hepatitis during the Eastern Nigerian epidemic of 1970-2 were followed up for two to nine years. One patient aged 60 years remained diabetic after the original illness. In the remaining 10 patients the diabetes remitted after three to nine months (mean 6.7 months) but in four it recurred after a remission lasting one and a half to four years (mean 2.6 years). Results of this follow-up study seem to confirm that the pancreas is sometimes permanently damaged during infectious hepatitis. PMID:435884

    Alcoholic hepatitis is a distinct clinical syndrome among people with chronic and active alcohol abuse, with a potential for 30%-40% mortality at 1 month among those with severe disease. Corticosteroids or pentoxifylline are the current pharmacologic treatment options, but they provide only about 50% survival benefit. These agents are recommended for patients with modified discriminant function (mDF) ≥ 32 or Model for End-Stage Liver Disease score ≥ 18. The Lille score is used to determine response to steroids. Currently, a minimum of 6 months of abstinence from alcohol use is required for patients to receive a liver transplant, a requirement that cannot be met by patients with severe alcoholic hepatitis nonresponsive to steroids (Lille score ≥ 0.45). Data are emerging on the benefit of liver transplantation in select patients with first episode of severe alcoholic hepatitis. This review also focuses on recent treatment trials in alcoholic hepatitis including liver transplantation and its associated controversies, as well as possible future targets and pharmacologic treatment options for patients with alcoholic hepatitis that are being pursued through upcoming consortium studies.

    Background HIV-infected (HIV+) men face cancer treatment disparities which impact outcome. Prostate cancer (PCa) treatment and treatment appropriateness in HIV+ men are unknown. Methods We used electronic chart review to conduct a retrospective cohort study of 43 HIV+ cases with PCa and 86 age- and race-matched HIV-uninfected (HIV−) controls with PCa, aged 40–79, from 2001–2012. We defined treatment appropriateness using National Comprehensive Cancer Network (NCCN) guidelines and the Charlson Co-morbidity Index (CCI) to estimate life expectancy. Results Median age was 59.5 years at PCa diagnosis. Median CD4+ T-cell count was 459.5cells/mm3, 95.3% received antiretroviral therapy, and 87.1% were virally suppressed. Radical prostatectomy (RP) was the primary treatment for 39.5% of HIV+ and 71.0% of HIV− men (p= 0.004). Only 16.3% of HIV+ vs. 57.0% of HIV− men received open RP (p< 0.001). HIV+ men received more radiotherapy (25.6% vs. 16.3%, p= 0.13). HIV was negatively associated with open RP (OR= 0.03, p= 0.007), adjusting for insurance and CCI. No men were undertreated. Fewer HIV+ men received appropriate treatment (89.2% vs. 100%, p= 0.003), due to 4 overtreated HIV+ men. Excluding AIDS from the CCI still resulted in fewer HIV+ men receiving appropriate treatment (94.6% vs. 100%, p = 0.03). Conclusion PCa in HIV+ men is largely appropriately treated. Under-or overtreatment may occur from difficulties in life expectancy estimation. HIV+ men may receive more radiotherapy and fewer RPs, specifically open RPs. Impact Research on HIV/AIDS survival indices and etiologies and outcomes of this PCa treatment disparity in HIV+ men is needed. PMID:25063519

    Porphyrias are divided into erythropoietic and hepatic manifestations. Erythropoietic porphyrias are characterized by cutaneous symptoms and appear in early childhood. Erythropoietic protoporphyria is complicated by cholestatic liver cirrhosis and progressive hepatic failure in 10%, of patients. Acute hepatic porphyrias (delta-aminolaevulinic acid dehydratase deficiency porphyria, acute intermittent porphyria, hereditary coproporphyria and variegate porphyria) are characterized by variable extrahepatic gastrointestinal, neurological-psychiatric and cardiovascular manifestations requiring early diagnosis to avoid life-threatening complications. Acute hepatic porphyrias are pharmacogenetic and molecular regulatory diseases (without porphyrin accumulation) mainly induced by drugs, sex hormones, fasting or alcohol. The disease process depends on the derepression of hepatic delta-aminolaevulinic acid synthase following haem depletion. In contrast to the acute porphyrias, nonacute, chronic hepatic porphyrias such as porphyria cutanea tarda are porphyrin accumulation disorders leading to cutaneous symptoms associated with liver disease, especially caused by alcohol or viral hepatitis. Alcohol, oestrogens, haemodialysis, hepatitis C and AIDS are triggering factors. Porphyria cutanea tarda is the most common porphyria, followed by acute intermittent porphyria and erythropoietic protoporphyria. The molecular genetics of the porphyrias is very heterogenous. Nearly every family has its own mutation. The mutations identified account for the corresponding enzymatic deficiencies, which may remain clinically silent throughout life. Thus, the recognition of the overt disorder with extrahepatic manifestations depends on the demonstration of biochemical abnormalities due to these primary defects and compensatory hepatic overexpression of hepatic delta-aminolaevulinic acid synthase in the acute porphyrias. Consequently, haem precursors are synthesized in excess. The increased

    Classical presentation of Histoplasma infection includes fever and respiratory symptoms. Opportunistic microorganisms must be suspected on immunocompromised patients who develop bizarre symptoms. We present a case of a female patient with rheumatoid arthritis who received treatment with Infliximab during one and a half year; she developed granulomatous hepatitis secondary to Histoplasma infection. The patient was admitted with acute hepatitis and thrombocytopenic coagulopathy. A liver biopsy was performed revealing granulomatous hepatitis, microvesicular steatosis, isolated apoptotic cells, and parenchyma microabscesses. PAS and Gömöri stains revealed areas with mycotic microorganisms morphologically compatible with Histoplasma spp. and confirmed by culture. PMID:25379301

  11. Social support among releasing men prisoners with lifetime trauma experiences.

    2014-01-01

    High rates of lifetime trauma experiences exist among men incarcerated in US state and federal prisons. Because lifetime trauma experiences have been linked to problematic behavioral and psychiatric outcomes for incarcerated populations, trauma-informed interventions could improve post-release well-being of releasing men prisoners with trauma histories. Social support has consistently been found to have a positive impact on trauma-related outcomes in non-incarcerated populations. Therefore, it is reasonable to hypothesize that social support may be an important intervention component for releasing men prisoners with trauma experiences; yet, the relationship between trauma experiences, psychiatric and behavioral factors, and social support has received almost no attention in research with men prisoners. Using a probability sample of 165 soon-to-be-released men, the present study examined differences in certain demographic, criminal justice history, mental health, substance abuse, and social support (type, quality, amount, and source) variables between releasing men prisoners with and without lifetime trauma experiences. Results indicate that men with trauma histories had more negative social support experiences and fewer positive social support resources before prison than their counterparts. Men with trauma histories also had more lifetime experiences with mental health and substance use problems. On further investigation of the subsample of men with trauma histories, those who were older, had substance use disorders, and histories of mental health problems anticipated fewer post-release social support resources. Study findings underscore the nuances of social support for men prisoners with trauma experiences and point to implications for future directions in targeted trauma-informed intervention development for releasing men prisoners.

    An improved long-life design for solar energy receivers provides for greatly reduced thermally induced stress and permits the utilization of less expensive heat exchanger materials while maintaining receiver efficiencies in excess of 85% without undue expenditure of energy to circulate the working fluid. In one embodiment, the flow index for the receiver is first set as close as practical to a value such that the Graetz number yields the optimal heat transfer coefficient per unit of pumping energy, in this case, 6. The convective index for the receiver is then set as closely as practical to two times the flow index so as to obtain optimal efficiency per unit mass of material.

    2011-01-01

    A receiver gain modulation circuit (RGMC) was developed that modulates the power gain of the output of a radiometer receiver with a test signal. As the radiometer receiver switches between calibration noise references, the test signal is mixed with the calibrated noise and thus produces an ensemble set of measurements from which ensemble statistical analysis can be used to extract statistical information about the test signal. The RGMC is an enabling technology of the ensemble detector. As a key component for achieving ensemble detection and analysis, the RGMC has broad aeronautical and space applications. The RGMC can be used to test and develop new calibration algorithms, for example, to detect gain anomalies, and/or correct for slow drifts that affect climate-quality measurements over an accelerated time scale. A generalized approach to analyzing radiometer system designs yields a mathematical treatment of noise reference measurements in calibration algorithms. By treating the measurements from the different noise references as ensemble samples of the receiver state, i.e. receiver gain, a quantitative description of the non-stationary properties of the underlying receiver fluctuations can be derived. Excellent agreement has been obtained between model calculations and radiometric measurements. The mathematical formulation is equivalent to modulating the gain of a stable receiver with an externally generated signal and is the basis for ensemble detection and analysis (EDA). The concept of generating ensemble data sets using an ensemble detector is similar to the ensemble data sets generated as part of ensemble empirical mode decomposition (EEMD) with exception of a key distinguishing factor. EEMD adds noise to the signal under study whereas EDA mixes the signal with calibrated noise. It is mixing with calibrated noise that permits the measurement of temporal-functional variability of uncertainty in the underlying process. The RGMC permits the evaluation of EDA by

    1974-01-01

    The effect of glucagon (50 ng/kg/min) on arterial glycerol concentration and net splanchnic production of total ketones and glucose was studied after an overnight fast in four normal and five insulin-dependent diabetic men. Brachial artery and hepatic vein catheters were inserted and splanchnic blood flow determined using indocyanine green. The glucagon infusion resulted in a mean circulating plasma level of 4,420 pg/ml. In the normal subjects, the glucagon infusion resulted in stimulation of insulin secretion indicated by rising levels of immunoreactive insulin and C-peptide immunoreactivity. Arterial glycerol concentration (an index of lipolysis) declined markedly and net splanchnic total ketone production was virtually abolished. In contrast, the diabetic subjects secreted no insulin (no rise in C-peptide immunoreactivity) in response to glucagon. Arterial glycerol and net splanchnic total ketone production in these subjects rose significantly (P=<0.05) when compared with the results in four diabetics who received a saline infusion after undergoing the same catheterization procedure. Net splanchnic glucose production rose markedly during glucagon stimulation in the normals and diabetics despite the marked rise in insulin in the normals. Thus, the same level of circulating insulin which markedly suppressed lipolysis and ketogenesis in the normals failed to inhibit the glucagon-mediated increase in net splanchnic glucose production. It is concluded (a) that glucagon at high concentration is capable of stimulating lipolysis and ketogenesis in insulin-deficient diabetic man; (b) that insulin, mole for mole, has more antilipolytic activity in man than glucagon has lipolytic activity; and (c) that glucagon, on a molar basis, has greater stimulatory activity than insulin has inhibitory activity on hepatic glucose release.

    Family physicians should carefully follow their patients receiving methyldopa for liver toxicity. Methyldopa is commonly used in treating hypertension and its hepatotoxic potential is frequently overlooked. This point is illustrated in the following case report involving a 45-year-old black female. The patient had been receiving oral methyldopa for 7.5 months prior to hospitalization for control of severe hypertension. Methyldopa was discontinued on her second hospital day when her liver tests were found to be abnormal. She developed progressive liver failure and lapsed into hepatic coma. Subsequently, her liver biopsy showed severe hepatic necrosis. She slowly improved with medical management. Her liver tests returned to normal; she resumed work and at 14 months follow up her liver biopsy showed no evidence of chronic active liver disease. Monitoring for methyldopa toxicity as outlined in this article could have prevented this costly and near lethal side effect. ImagesFig. 1Fig. 2 PMID:21289717

    2015-01-01

    Alcoholic liver disease is one of the most prevalent liver diseases worldwide, and a major cause of morbidity and mortality. Alcoholic hepatitis is a severe form of liver injury in patients with alcohol abuse, can present as an acute on chronic liver failure associated with a rapid decline in liver synthetic function, and consequent increase in mortality. Despite therapy, about 30%–50% of patients with severe alcoholic hepatitis eventually die. The pathogenic pathways that lead to the development of alcoholic hepatitis are complex and involve oxidative stress, gut dysbiosis, and dysregulation of the innate and adaptive immune system with injury to the parenchymal cells and activation of hepatic stellate cells. As accepted treatment approaches are currently limited, a better understanding of the pathophysiology would be required to generate new approaches that improve outcomes. This review focuses on recent advances in the diagnosis, pathogenesis of alcoholic hepatitis and novel treatment strategies. PMID:26540078

    Hepatitis E virus (HEV) has a worldwide distribution and is known to cause acute and fulminant hepatitis. However, over the last few years, it has been shown to also cause chronic hepatitis and cirrhosis in immunosuppressed patients, especially solid-organ-transplant patients. In immunocompetent and immunosuppressed patients, HEV is also associated with extra-hepatic manifestations, such as neurological symptoms and kidney injury. Unfortunately, a diagnostic assay for HEV infection is still not available in all countries. Reduction of immunosuppression is the first-line therapeutic option for organ-transplant patients with chronic hepatitis. In addition, ribavirin is highly efficient at treating chronic HEV infection. In this comprehensive review, we summarize the current knowledge regarding HEV diagnosis, its natural history, clinical manifestations, and treatments in patients with a solid-organ transplant.

    Purpose We know little about the prevalence of sexting behavior among young men who have sex with men (YMSM) or its association with their sexual behaviors. Methods To address these gaps, we used data from an online study examining the partner-seeking behaviors of single YMSM (N=1,502; ages 18–24) in the U.S. Most participants (87.5%) reported sexting, with 75.7% of the sample reporting having sent and received a sext. Results Sexting was more frequent among sexually-active YMSM, with YMSM who had sent and received a sext being more likely to report insertive anal intercourse, with and without condoms, than those who had not sexted. We found no association between sexting and receptive anal intercourse. Conclusions Our findings suggest that sexting may vary by YMSM’s sexual roles. We discuss our findings with attention to their implications for sexual health promotion. PMID:24361235

    Nocturia is a common and bothersome symptom that impacts on sleep-quality and quality of life. Nocturia often has a multi-factorial etiology which makes thorough assessment of the complaint indispensable. This review summarizes the definition of nocturia, its epidemiology, clinical presentation, pathophysiology, diagnostics, and treatment options with special reference to older men. Nocturia is defined as a nocturnal voiding frequency of two or more, based on impact on quality of life. It is very prevalent in older men. Apart from the negative effects of sleep-disruption, it may be a risk-factor for hip fractures and increased mortality. Most common causes are: nocturnal polyuria, 24-h polyuria, overactive bladder (sometimes due to BPH) and sleep disturbance. A clear understanding of the etiology in the individual patient is indispensable when addressing the various possible causes and co-morbidities. Most important tool for this is the frequency-volume chart, but also patient history, physical examination and serum analysis. For treatment, lifestyle adjustments are often helpful. Medical therapy with 5-alpha reductase inhibitors, alpha-blockers, a combination of the two, or anti-muscarinics, has a limited effect. Most important medical option is desmopressin (arginine vasopressin analogue); however, treatment with this drug is limited to men under 65 years mainly due to the risk of hyponatraemia.

    Transgender people have experienced significant advances in societal acceptance despite experiencing continued stigma and discrimination. While it can still be difficult to access quality health care, and there is a great deal to be done to create affirming health care organizations, there is growing interest around the United States in advancing transgender health. The focus of this commentary is to provide guidance to clinicians caring for transgender men or other gender nonconforming people who are contemplating, carrying, or have completed a pregnancy. Terms transgender and gender nonconforming specifically refer to those whose gender identity (e.g., being a man) differs from their female sex assigned at birth. Many, if not most transgender men retain their female reproductive organs and retain the capacity to have children. Review of their experience demonstrates the need for preconception counseling that includes discussion of stopping testosterone while trying to conceive and during pregnancy, and anticipating increasing experiences of gender dysphoria during and after pregnancy. The clinical aspects of delivery itself fall within the realm of routine obstetrical care, although further research is needed into how mode and environment of delivery may affect gender dysphoria. Postpartum considerations include discussion of options for chest (breast) feeding, and how and when to reinitiate testosterone. A positive perinatal experience begins from the moment transgender men first present for care and depends on comprehensive affirmation of gender diversity. PMID:27030799

    Tamoxifen is an off-label option to treat men for breast cancer, infertility, and idiopathic gynecomastia. Lately, tamoxifen has been proposed as a treatment to prevent gynecomastia in prostate cancer patients receiving antiandrogen therapy. We reviewed the adverse events (AEs) reported in studies of men prescribed tamoxifen for these conditions to better understand its side-effect profile. We searched PubMed for randomized controlled trials (RCTs) that included safety data of tamoxifen treatment in men with prostate cancer, breast cancer, infertility, and idiopathic gynecomastia. Non-RCTs were also reviewed. The results demonstrate that the AE profile in tamoxifen-treated male populations varied. Excluding breast events, gastrointestinal, and cardiovascular problems were the most commonly reported AEs in prostate cancer patients, whereas more psychiatric disorders were reported in male breast cancer patients. Few AEs have been documented in men receiving tamoxifen for infertility and idiopathic gynecomastia. Less than 5% of men withdrew from tamoxifen therapy because of toxicity. This suggests that for most men, tamoxifen is well-tolerated. Of those who discontinued tamoxifen, the majority were male breast cancer patients, and cardiovascular events were the most common reason for stopping tamoxifen treatment. Unfortunately, in many cases, the reasons for withdrawing tamoxifen were unspecified. Based on the available evidence, tamoxifen's AE profile appears to vary depending upon which male population is treated. Also, the frequency at which AEs occur varies - less AEs in men with infertility and idiopathic gynecomastia compared to men with prostate cancer or breast cancer. Long-term studies that rigorously document the side-effect profile of tamoxifen in men are lacking. PMID:27152880

    We receive around 60 cases of hepatic abscess in a year. The commonest diagnosis reached at the time of discharge is amoebic liver abscess. The diagnosis of amoebic liver abscess is mostly presumptive and thus the patients are usually given a mixed treatment with injection ceftriaxone and tablet metronidazole. Here we report three cases of hepatic abscess diagnosed recently, where ascariasis was the probable etiology. Ascariasis may be a much commoner cause of hepatic abscesses in this region than we think. PMID:26068350

    2015-09-01

    Chronic hepatitis C (CHC) is accompanied by numerous metabolic disorders, partially associated with altered adipokine system regulation. Omentin (intelectin-1) is a novel adipokine known to play a pivotal role in metabolic regulation in CHC. In a group of 63 CHC patients (29 men/34 women) infected with genotype 1b, aged 6.6 ± 14.6 years, serum omentin levels and its gene expression in liver tissue were examined and their association with metabolic and histopathological features was assessed. Serum omentin levels were significantly higher in CHC patients compared to controls (p < 0.001), regardless of sex, body mass index (BMI), insulin sensitivity and lipid concentrations. There was no correlation between serum omentin and omentin hepatic expression. Neither parameter was associated with any histological features. Serum omentin in non-obese CHC patients seems not to be related to metabolic disorders or liver pathology. Omentin hepatic expression shows no relationship with either serum omentin levels or histopathological features. This suggests different mechanisms regulating circulating omentin concentration and omentin hepatic expression in CHC. PMID:26619101

    Hepatitis C virus has been shown to be responsible for most cases of posttransfusion hepatitis, as well as for sporadic non-A, non-B viral hepatitis. Hepatitis C virus has also been implicated in the development of primary hepatocellular carcinoma, autoimmune hepatitis, and fulminant viral hepatitis. Although the role of the parenteral transmission of hepatitis C virus is well established, its route of transmission in cases of sporadic infection remains unclear. Sexual transmission is suspected but not confirmed. Recent work regarding treatment has shown interferon alfa to be effective, but the discontinuation of therapy is associated with a 50% relapse rate. PMID:1656611

    Background: Pre-exposure prophylaxis (PrEP) with daily oral emtricitabine and tenofovir disoproxil fumarate (FTC/TDF) prevents HIV infection. The safety and feasibility of HIV PrEP in the setting of hepatitis B virus (HBV) infection were evaluated. Methods: The Iniciativa Profilaxis Pre-Exposición study randomized 2499 HIV-negative men and transgender women who have sex with men to once-daily oral FTC/TDF versus placebo. Hepatitis serologies and transaminases were obtained at screening and at the time PrEP was discontinued. HBV DNA was assessed by polymerase chain reaction, and drug resistance was assessed by population sequencing. Vaccination was offered to individuals susceptible to HBV infection. Results: Of the 2499 participants, 12 (0.5%; including 6 randomized to FTC/TDF) had chronic HBV infection. After stopping FTC/TDF, 5 of the 6 participants in the active arm had liver function tests performed at follow-up. Liver function tests remained within normal limits at post-stop visits except for a grade 1 elevation in 1 participant at post-stop week 12 (alanine aminotransferase = 90, aspartate aminotransferase = 61). There was no evidence of hepatic flares. Polymerase chain reaction of stored samples showed that 2 participants in the active arm had evidence of acute HBV infection at enrollment. Both had evidence of grade 4 transaminase elevations with subsequent resolution. Overall, there was no evidence of TDF or FTC resistance among tested genotypes. Of 1633 eligible for vaccination, 1587 (97.2%) received at least 1 vaccine; 1383 (84.7%) completed the series. Conclusions: PrEP can be safely provided to individuals with HBV infection if there is no evidence of cirrhosis or substantial transaminase elevation. HBV vaccination rates at screening were low globally, despite recommendations for its use, yet uptake and efficacy were high when offered. PMID:26413853

    2003-03-01

    The theoretical directivity of a single combined acoustic receiver, a device that can measure many quantities of an acoustic field at a collocated point, is presented here. The formulation is developed using a Taylor series expansion of acoustic pressure about the origin of a Cartesian coordinate system. For example, the quantities measured by a second-order combined receiver, denoted a dyadic sensor, are acoustic pressure, the three orthogonal components of acoustic particle velocity, and the nine spatial gradients of the velocity vector. The power series expansion, which can be of any order, is cast into an expression that defines the directivity of a single receiving element. It is shown that a single highly directional dyadic sensor can have a directivity index of up to 9.5 dB. However, there is a price to pay with highly directive sensors; these sensors can be significantly more sensitive to nonacoustic noise sources. PMID:12656387

    1983-01-01

    An improved tower-mounted central solar energy receiver for heating air drawn through the receiver by an induced draft fan. A number of vertically oriented, energy absorbing, fin-shaped slats are radially arranged in a number of concentric cylindrical arrays on top of the tower coaxially surrounding a pipe having air holes through which the fan draws air which is heated by the slats which receive the solar radiation from a heliostat field. A number of vertically oriented and wedge-shaped columns are radially arranged in a number of concentric cylindrical clusters surrounding the slat arrays. The columns have two mirror-reflecting sides to reflect radiation into the slat arrays and one energy absorbing side to reduce reradiation and reflection from the slat arrays.

    HIV infection and viral hepatitis due to HBV and HCV infection are major causes of chronic disease worldwide, and share some common routes of transmission, epidemiology, initial barriers faced in treatment access, and in strategies for a global public health response. Testing and diagnosis of HIV, HBV, and HCV infection is the gateway for access to both care and treatment and prevention services, and crucial for an effective HIV and hepatitis epidemic response. In this review article, we first summarize the common goals and guiding principles in a public health approach to HIV and hepatitis testing. We summarize the impressive global progress in HIV testing scale-up and evolution of approaches, with expansion of provider-initiated testing and counseling in clinical settings (particularly antenatal and tuberculosis clinics), the introduction of more community based testing services, and use of rapid diagnostic tests enabling provision of same-day test results. However, 46% of all people living with HIV are still unaware of their serostatus, and many continue to be diagnosed and start antiretroviral therapy late. As testing and treatment scale-up accelerates for an "treat all" approach, other challenges to address include how to better focus testing and reach those yet undiagnosed and most at risk, especially key populations, men, adolescents, and children. We summarize future directions in HIV testing to speed scale-up and close gaps that are addressed in the WHO 2015 consolidated HIV testing guidelines. In contrast to HIV, action in hepatitis testing and treatment has been fragmented and limited to a few countries, and there remains a large burden of undiagnosed cases globally. We summarize key challenges in the hepatitis testing response, including lack of simple, reliable, and low-cost diagnostic tests, laboratory capacity, and testing facilities; inadequate data to guide country specific hepatitis testing approaches and who to screen; stigmatization and social

  14. Current and future treatments of osteoporosis in men.

    One in three osteoporotic fractures occur in men and the consequences of a fracture in men tend to be more severe than in women. Still, only a small minority of men with high risk of fracture are detected and treated. Although there are gender differences in the pathophysiology of osteoporosis, such as in the pattern of bone loss, similarities predominate, which is also the case for clinical risk factors. It seems appropriate to consider treatment for men and women with a similar 10 year fracture risk. Drugs now approved for treatment of osteoporosis in men include the anti-resorptive bisphosphonates alendronate, residronate and zoledronic acid, the anti-resorptive drug denosumab, the bone-forming agent teriparatide, and (not in the US) strontium ranelate with mild opposite effects on resorption and formation. Although the evidence level for efficacy and safety of these drugs in men is still relatively limited, available data indicate that treatment effects in men are very similar to what has been observed in the treatment of postmenopausal osteoporosis. Denosumab is also approved for treatment in men receiving androgen deprivation therapy for non-metastatic prostate cancer; bisphosphonates and teriparatide are also available to clinicians for treatment of glucocorticoid-induced osteoporosis in men. Testosterone treatment may be indicated in men with documented symptomatic hypogonadism, but osteoporosis is neither a sufficient nor a specific indication for testosterone treatment. New compounds with well advanced clinical development include odanacatib, a selective inhibitor of the cysteine protease cathepsin-K, and romosozumab, a monoclonal antibody against sclerostin.

    Eradication of chronic hepatitis C virus (HCV) infection is now possible with all oral antiviral medications, including the combination of ombitasvir, paritaprevir, dasabuvir, and ritonavir (PrOD) with or without ribavirin. While high rates of sustained virologic response (SVR) can be achieved, a small subset of patients experience on-treatment liver enzyme elevations, in particular women using concurrent estradiol-containing oral contraceptive medications (OCPs). Herein, we describe four cases of liver enzyme elevations within 2-3 weeks of PrOD initiation in African-American men infected with HCV genotype 1a or 1b. Three patients with varying degrees of hepatic fibrosis received a full treatment course without medication modification, achieved SVR, and experienced resolution of liver enzyme abnormalities. One patient with cirrhosis was switched mid-treatment to an alternate HCV regimen, experienced subsequent resolution of liver enzyme abnormalities, and achieved SVR. In summary, these cases suggest that all HCV patients treated with PrOD, independent of gender or concurrent medications, should have laboratory monitoring for liver enzyme elevations, with a particular emphasis on early monitoring in cirrhotic patients.

    Approximately 240 million people are chronically infected with hepatitis B virus (HBV), 75% of whom reside in Asia. Approximately 600000 of infected patients die each year due to HBV-related diseases or hepatocellular carcinoma (HCC). The endemicity of hepatitis surface antigen in Indonesia is intermediate to high with a geographical difference. The risk of HBV infection is high in hemodialysis (HD) patients, men having sex with men, and health care workers. Occult HBV infection has been detected in various groups such as blood donors, HD patients, and HIV-infected individuals and children. The most common HBV subgenotype in Indonesia is B3 followed by C1. Various novel subgenotypes of HBV have been identified throughout Indonesia, with the novel HBV subgenotypes C6-C16 and D6 being successfully isolated. Although a number of HBV subgenotypes have been discovered in Indonesia, genotype-related pathogenicity has not yet been elucidated in detail. Therefore, genotype-related differences in the prognosis of liver disease and their effects on treatments need to be determined. A previous study conducted in Indonesia revealed that hepatic steatosis was associated with disease progression. Pre-S2 mutations and mutations at C1638T and T1753V in HBV/B3 have been associated with advanced liver diseases including HCC. However, drug resistance to lamivudine, which is prominent in Indonesia, remains obscure. Although the number of studies on HBV in Indonesia has been increasing, adequate databases on HBV infection are limited. We herein provided an overview of the epidemiology and clinical characteristics of HBV infection in Indonesia. PMID:26478663

    Data on prevalence of hepatitis E virus (HEV) in Malawi is limited. We tested blood samples from HIV-uninfected and -infected populations of women and men enrolled in research studies in Malawi during 1989–2008 to determine the seroprevalence of HEV, hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Samples were tested for IgG against HEV, total antibodies against HAV and HCV, and presence of HBV surface antigens. Of 800 samples tested, 16.5% were positive for HEV IgG, 99.6% were positive for HAV antibodies, 7.5% were positive for HBV surface antigen, and 7.1% were positive for HCV antibodies. No clear trends over time were observed in the seroprevalence of HEV, and HIV status was not associated with hepatitis seroprevalence. These preliminary data suggest that the seroprevalence of HEV is high in Malawi; the clinical effects may be unrecognized or routinely misclassified. PMID:26079666

    1988-01-01

    A medium-size Beacon Receiving System for reception and processing of the B1 (20 GHz) and B2 (30 GHz) beacons from Olympus has been developed. Integration of B1 and B2 receiving equipment into one system using one antenna and a common computer for control and data processing provides the advantages of a compact configuration and synchronization of the two receiver chains. Range for co-polar signal attenuation meaurement is about 30 dB for both beacons, increasing to 40 dB for B2 if the receivers are synchronized to B1. The accuracy is better than 0.5 dB. Cross-polarization discriminations of the order of 10 to 30 dB may be determined with an accuracy of 1 to 2 dB. A number of radiometers for complementary measurements of atmospheric attenuation of 13 to 30 GHz has also been constructed. A small multi-frequency system for operation around 22 GHz and 31 GHz is presently under development.

    If the occurrence of hepatitis E virus antibody (anti-HEV) in regions where the disease is not endemic represents infection, rates may be greater in high-risk populations and behavioral correlates may reflect recognized transmission modes. Serum samples from 300 homosexual males, 300 injection drug users (IDUs), and 300 blood donors from Baltimore, Md., were tested for anti-HEV by enzyme immunoassay. Anti-HEV was found in an unexpectedly high percentage of homosexual men (15.9%) and IDUs (23.0%). However, anti-HEV was present in a similar proportion of blood donors (21.3%) (P > 0.05), while hepatitis A, B, and C virus antibodies were more prevalent in the high-risk groups (P < 0.001). Among homosexual men, anti-HEV was not significantly correlated with a history of hepatitis, high-risk sexual practices, or sexually transmitted infections, in contrast to hepatitis A and B antibodies. Among IDUs, anti-HEV was not significantly associated with a history of hepatitis or high-risk drug-using practices, as was found with hepatitis C antibodies. In a setting without endemic hepatitis E disease, there was no evidence that anti-HEV reflected subclinical infection. Until the basis for HEV seroreactivity in such areas is elucidated, anti-HEV results should be interpreted with caution. PMID:9114415

    PubMed Central

    Krugman, Saul

    1974-01-01

    Recent advances in hepatitis research have shed new light on the etiology, pathogenesis, epidemiology and prevention of type B hepatitis infection. The so-called ‘Dane’ particle is probably the complete hepatitis B virion; its outer coat is the hepatitis B (Australia) antigen (HB Ag) and its inner core is an immunologically distinct particle. Subtypes of HB Ag (a, d, y, w and r) are useful indices for epidemiological surveys. Concepts of epidemiology have changed: type B hepatitis is transmissible by contact as well as by inoculation. The presence of HB Ag in blood is indicative of the presence of hepatitis B virus. Tests to detect antigen and use of voluntary blood donors have played a major role in the decreased incidence of post transfusion hepatitis. A special hepatitis B gammaglobulin preparation and a heat-inactivated hepatitis B vaccine have proved to be effective in preliminary studies. PMID:4219230

    Although men's cancer experiences have received limited attention within the field of psychosocial oncology, increasing attention is being devoted to the development and evaluation of men-centered programs. This scoping review describes this emergent body of literature, detailing the focus, participation, and impact of interventions designed to help men with cancer build illness-specific knowledge, adapt to illness, manage side effects, distress, and uncertainty, sustain relationships, and more. Striving to build on existing knowledge, research gaps and opportunities are discussed, including a need for stronger methodologies, more tailored and targeted supports, attention to the experiences of men with nonprostate cancers, and the explicit integration of gender analyses in the research process.

    1986-01-01

    Methotrexate (MTX) has been implicated in the pathogenesis of hepatic fibrosis. However, no information exists regarding the effects of MTX on hepatic collagen metabolism. Therefore, the authors studied the role of MTX in hepatic collagen production in vivo in rats receiving an 8-week course of varying doses of MTX. Twenty-four hours prior to sacrifice animals received an injection of (5-/sup 3/H)proline. Collagen was extracted with hot trichloroacetic acid and the protein-bound (/sup 3/H)hydroxyproline was used as a measure of de novo collagen production. The hepatic collagen content was essentially the same in the control and treatment groups in spite of evidence of hepatotoxicity. Similarly, no significant differences were present among the control and MTX-treated groups in the de novo absolute collagen production. In summary, they found no evidence of increased hepatic fibrogenesis in small groups of animals after 8 weeks of treatment with MTX. Data clearly supporting the claim that MTX itself is responsible for hepatic fibrosis are lacking.

  7. Men at sport: gay men's experiences in the sport workplace.

    PubMed

    Cavalier, Elizabeth S

    2011-01-01

    Research on sexual identity and sport has revealed a shifting narrative about the experiences of gay men. While some suggest the atmosphere is hostile, others posit that homophobia and sexual prejudice are playing less of a role in gay men's experiences. This research focuses on the experiences of 10 gay men working in professional, collegiate, and club sport, as part of a larger dataset of 37 male and female employees. Five of the men were overtly and publicly out at work, while five were closeted (to varying degrees). This article focuses on three themes for gay men working in sport: 1) the importance of coming out in the workplace; 2) the role of the locker room as a contested terrain, and 3) the disconnect between their experiences at work and their perceptions of the workplace environment as negative or positive. Men in this study were basing their impressions on their total experience in sport (as current and former players, as employees, and as fans). It also suggests that the public "story" of gay men working in sport represents one of two extremes-either the proverbial "horror story," or the extremely positive representation of gay men's experiences. This research suggests that gay men's experiences in sport are more complex and nuanced than the public narrative implies. PMID:21534074

    Imaging plays a significant role in the detection, characterization and treatment of hepatic infections. Infectious diseases of the liver include pyogenic and amoebic abscesses and parasitic, fungal, viral and granulomatous infections. With increases in worldwide travel, immunosuppression and changing population demographics, identification of cases of hepatic infection is becoming more common in daily practice. Knowledge of the imaging features seen with hepatic infections can assist in early diagnosis and timely initiation of appropriate therapy. This review presents the imaging appearances of hepatic infections, emphasizing specific features that may contribute to the diagnosis. Examples of the imaging findings seen with pyogenic and amoebic abscesses, infection with Echinococcus granulosus (Hydatid), schistosomiasis, candidiasis and tuberculosis (TB) are presented.

    2002-11-01

    The human hereditary hepatic porphyrias are diseases due to marked deficiencies of enzymes in the heme biosynthetic pathway. Porphyrias can be classified as either hepatic or erythroid, depending on the major production site of porphyrins or their precursors. The pathogenesis of inherited hepatic porphyrias has now been defined at the molecular level. Some gene carriers are vulnerable to a range of exogenous and endogenous factors, which may trigger neuropsychiatric and/or cutaneous symptoms. Early diagnosis is of prime importance since it makes way for counselling. In this article we present an overview of recent advances on hepatic porphyrias: 5-aminolevulinic acid dehydratase deficiency porphyria, acute intermittent porphyria (AIP), porphyria cutanea tarda (PCT), hereditary coproporphyria (HC), and variegate porphyria (VP).

Here we describe the use PVA as a salvage procedure following accidental injury of the hepatic artery to the remnant liver occurred during left hepatic trisectionectomy for colorectal liver metastases (CRLM). A 60-year-old man with cancer of the sigmoid colon and initially unresectable CRLM received 11 cycles of hepatic arterial infusion chemotherapy with 5-fluorouracil (1500 mg/week), after which CRLM was downstaged to resectable. One month after laparoscopic sigmoidectomy, a left trisectionectomy and wedge resection of segment 6 were performed. The posterior branch of the right hepatic artery, the only feeding artery to the remnant liver, was injured and totally dissected. Because microsurgical reconstruction of the artery was impossible, PVA was used; PVA is the sole known procedure available when hepatic artery reconstruction is impossible. The patient then suffered portal hypertension, and closure of arterio-portal anastomosis using an interventional technique with angiography was eventually performed on postoperative day 73. Therefore, it is considered that because PVA is associated with severe postoperative portal hypertension, closure of the arterio-portal shunt should be performed as soon as possible on diagnosing portal hypertension.

    2015-08-01

    WHO estimates reveal that the global prevalence of viral hepatitis may be as high as 500 million, with an annual mortality rate of up to 1.3 million individuals. The majority of this global burden of disease is borne by nations of the developing world with high rates of vertical and iatrogenic transmission of HBV and HCV, as well as poor access to healthcare. In 2013, 3.2% of the global population (231 million individuals) migrated into a new host nation. Migrants predominantly originate from the developing countries of the south, into the developed economies of North America and Western Europe. This mass migration of individuals from areas of high-prevalence of viral hepatitis poses a unique challenge to the healthcare systems of the host nations. Due to a lack of universal standards for screening, vaccination and treatment of viral hepatitis, the burden of chronic liver disease and hepatocellular carcinoma continues to increase among migrant populations globally. Efforts to increase case identification and treatment among migrants have largely been limited to small outreach programs in urban centers, such that the majority of migrants with viral hepatitis continue to remain unaware of their infection. This review summarizes the data on prevalence of viral hepatitis and burden of chronic liver disease among migrants, current standards for screening and treatment of immigrants and refugees, and efforts to improve the identification and treatment of viral hepatitis among migrants.

    Sera from one hundred and fifty nine Malaysian individuals were screened for the prevalence of delta markers. These included 15 HBsAg positive homosexuals, 16 acute hepatitis B cases, 9 chronic hepatitis B patients, 13 healthy HBsAg carriers and 106 intravenous (i.v.) drug abusers, of whom 27 were positive for HBsAg only and the rest were anti-HBc IgG positive but HBsAg negative. The prevalence of delta markers in the homosexuals was found to be 6.7%, in the HBsAg positive drug abusers 17.8%, in acute hepatitis B cases 12.5%. No evidence of delta infection was detected in healthy HBsAg carriers, chronic hepatitis B cases and HBsAg negative i.v. drug abusers. With reference to i.v. drug abusers, the prevalence of delta markers was higher in Malays (23%) than in Chinese (7%) although the latter had a higher HBsAg carrier rate. Although the HBsAg carrier rate in the homosexuals was high, their delta prevalence rate was low as compared to drug abusers. In Malaysia, as in other non-endemic regions, hepatitis delta virus transmission appeared to occur mainly via the parenteral and sexual routes. This is the first time in Malaysia that a reservoir of delta infection has been demonstrated in certain groups of the population at high risk for hepatitis B. PMID:3787309

  6. A digital beacon receiver

    Ransome, Peter D.

    1988-01-01

    A digital satellite beacon receiver is described which provides measurement information down to a carrier/noise density ratio approximately 15 dB below that required by a conventional (phase locked loop) design. When the beacon signal fades, accuracy degrades gracefully, and is restored immediately (without hysteresis) on signal recovery, even if the signal has faded into the noise. Benefits of the digital processing approach used include the minimization of operator adjustments, stability of the phase measuring circuits with time, repeatability between units, and compatibility with equipment not specifically designed for propagation measuring. The receiver has been developed for the European Olympus satellite which has continuous wave (CW) beacons at 12.5 and 29.7 GHz, and a switched polarization beacon at 19.8 GHz approximately, but the system can be reconfigured for CW and polarization-switched beacons at other frequencies.

We examined the influence of sex on progression to significant liver fibrosis in HIV-HCV co-infected adults receiving antiretroviral therapy (ART) using the aspartate aminotransferase-to-platelet ratio index (APRI) as a surrogate biomarker of liver fibrosis. Methods We evaluated 308 HIV infected, HCV RNA positive participants of a Canadian multicentre prospective cohort receiving antiretrovirals and without significant liver fibrosis or end-stage liver disease at baseline. We used multivariate discrete-time proportional hazards models to assess the effect of sex on time to significant fibrosis (APRI≥1.5) adjusting for baseline age, alcohol use, cigarette smoking, HCV duration, and APRI and time-updated CD4 count and HIV RNA. Results Overall, 55 (18%) participants developed an APRI ≥ 1.5 over 544 person-years of at-risk follow-up time; 18 (21%) women (incidence rate (IR)=14.0/100 PY; 7.5-20.4) and 37 (17%) men (IR=8.9/100 PY; 6.0-11.8). Women had more favourable profiles with respect to traditional risk factors for liver disease progression (younger, shorter duration of HCV infection and less alcohol use). Despite this, female sex was associated with a greater than two-fold increased risk of fibrosis progression (adjusted hazard rate (HR) =2.23; 1.22-4.08). Conclusions HIV-HCV co-infected women receiving antiretroviral therapy were at significantly greater risk of progressing to liver fibrosis as measured by APRI compared with men. Enhanced efforts to engage and treat co-infected women for HCV are needed. PMID:26090666

    Varicocele is an important cause of infertility in men. The exact mechanism by which varicocele depresses spermatogenesis is unknown but probably the retrograde flow of blood rich in catecholamines into the testes plays a major role. Because subfertile semen qualities are present in a large percentage of men with varicocele and because the response to surgical procedures is very good, high ligation of the left internal spermatic vein is recommended in men with varicocele and infertility.

    Background HPV infection has been associated with a wide range of psychosocial responses among women; however, few studies have examined emotional responses among men. Purpose To examine psychosocial differences among self-reported HPV-positive and HPV-negative Florida men who were tested for HPV. Method Men (n=536) in a natural history study of HPV completed a cross-sectional psychosocial survey between 2007 and 2010. Results Most participants were White, non-Hispanic, unmarried and had some college education. HPV knowledge was high, with no statistically significant differences between groups. Significantly higher negative emotional responses and perceived threat scores were found among HPV-positive men (p<0.05). The majority of men (91%) reported they were very likely or likely to get the HPV vaccine if it became available for men, but identified barriers as factors to consider. HPV-negative men were significantly more likely to tell a sex partner their test results than HPV-positive men. Conclusions Men experienced a range of negative emotions after receiving HPV test results, but most disclosed their test result to their sexual partner and reported high intentions to receive the HPV vaccine in the future. Findings should be considered when implementing health-related interventions among men to assist in decreasing psychosocial sequalae associated with HPV. PMID:23026036

    Abstract Hepatic steatosis assessment is of paramount importance for living liver donor selection because significant hepatic steatosis can affect the postoperative outcome of recipients and the safety of the donor. The validity of various noninvasive imaging methods to assess hepatic steatosis remains controversial. The purpose of our study is to investigate the association between noninvasive imaging methods and pathology to detect steatosis in living liver donors and to propose a prediction model for hepatic steatosis. Liver stiffness measurements (LSMs) and controlled attenuation parameter values in vibration controlled transient elastography, ultrasonography, computed tomography (CT), and magnetic resonance imaging were used as pretransplant screening methods to evaluate living liver donors between 2012 and 2014. Only 1 pathologist assessed tissue sample for hepatic steatosis. The median age of the 79 living donors (53 men and 26 women) was 32 years (16–68 years). The CT liver–spleen attenuation (L–S) difference and the controlled attenuation parameter values were well correlated with the level of hepatic steatosis on liver pathology. Multivariate analysis showed that liver stiffness measurement (LSM) (β = 0.903; 95% CI, 0.105–1.702; P = 0.027) and the CT L to S attenuation difference (β = −3.322; 95% CI, −0.502 to −0.142; P = 0.001) were closely associated with hepatic steatosis. We generated the following equation to predict total hepatic steatosis: Hepatic steatosis = 0.903 × LSM – 0.322 × CT L to S attenuation difference (AUC = 86.6% and P = 0.001). The values predicted by the equation correlated well with the presence of hepatic steatosis (r = 0.509 and P < 0.001). The combination of nonenhanced CT L to S attenuation difference and transient elastography using vibration controlled transient elastography provides sufficient information to predict hepatic steatosis in living liver donor

    Health, facial and vocal attributes and body height of men may affect a diverse range of social outcomes such as attractiveness to potential mates and competition for resources. Despite evidence that each parameter plays a role in mate choice, the relative role of each and inter-relationships between them, is still poorly understood. In this study, we tested relationships both between these parameters and with testosterone and immune function. We report positive relationships between testosterone with facial masculinity and attractiveness, and we found that facial masculinity predicted facial attractiveness and antibody response to a vaccine. Moreover, the relationship between antibody response to a hepatitis B vaccine and body height was found to be non-linear, with a positive relationship up to a height of 188 cm, but an inverse relationship in taller men. We found that vocal attractiveness was dependent upon vocal masculinity. The relationship between vocal attractiveness and body height was also non-linear, with a positive relationship of up to 178 cm, which then decreased in taller men. We did not find a significant relationship between body height and the fundamental frequency of vowel sounds provided by young men, while body height negatively correlated with the frequency of second formant. However, formant frequency was not associated with the strength of immune response. Our results demonstrate the potential of vaccination research to reveal costly traits that govern evolution of mate choice in humans and the importance of trade-offs among these traits.

    DKT International is a non-profit social marketing enterprise whose mission is to provide safe, affordable options for family planning and STI/HIV prevention. In Brazil, DKT sells male and female condoms to mostly lower-income couples nationwide. This paper is about the introduction of a ribbed, lubricated, latex condom called Affair to the Brazilian market in 2000. Sales were initially very low, but based on reports that Affair was well liked by some men who have sex with men, we took the opportunity to give Affair that positioning. We worked with our advertising agency, a local research company and Dignidade, a Brazilian NGO working for the rights of men who have sex with men. Two new products--a baggy condom called Affair Sensation and a complimentary lubricating gel called Affair Personal Lubricant--with new packaging and a promotional campaign were launched in February 2006. The billboard advertisement generated controversy in São Paulo, where the Advertising Council required it to be taken down due to complaints. However, the controversy helped promotion and at the same time generated public debate on sexuality and human rights. Our overall experience has been positive, sales are up and we have received messages of support for the products and their promotion from consumers. PMID:17101423

    Introduction Hepatitis B vaccination has been integrated into National Expanded Program on Immunization in Iran since the year 1993 and young adult national vaccination project was done in 2008. So we have three subpopulations with vaccination coverage for hepatitis B and different antibody levels. Consisting of Subpopulation 1 born after 1993, subpopulation 2 born between 1989 and 1993 and receiving vaccination under adult national project, and subpopulation 3 born prior to the year 1989. Aim The present study was conducted to investigate community protection by hepatitis B vaccine in adult population in an accessible population in Iran and compare vaccination coverage, HBs Ab level, and its effective titration among the three above-mentioned subpopulations. Materials and Methods This cross-sectional study was done on a 3000-individual adult population from all seven counties of Chaharmahal and Bakhtiari province enrolled by clustering. After obtaining written consent and filling out a questionnaire of demographic data and history of hepatitis B vaccination by trained interviewers, necessary blood sample was taken and HBs Ab titration was checked. The data were analysed by chi-square in SPSS 19. The level of significance was considered as 0.05 and effective Ab titration as ≥ 10. Results The mean age of the participants was 38.4±16.3 years. Of the participants 48.2% had effective titration. For vaccination coverage, 77.4% were unvaccinated, 20% completely vaccinated, and 2.6% incompletely vaccinated with a significant association with effective titration (p<0.001). Eighty six percent of the subpopulation 1 and 79% of the subpopulation 2 were completely vaccinated, with a significant difference in effective titration between them (p<0.001). Vaccination coverage was higher in men and the single but equal in cities and villages. The effective titration was significantly associated with being married and residence place (p=0.003). There was a significant association

    There is little research involving the US male population regarding weight control and behavior that may affect weight status. Gender-specific weight-control programs for men aren't the standard. Our study objectives were to survey dieting and health habits of an adult male employee population and to determine if the population would be interested in gender-specific programming. Demographics, weight-control practices and interest in gender-specific weight-control programs were examined cross sectionally. A 50-question web-based survey was posted via email from October 2-30, 2014 to male employees at a Mid-Atlantic university. Statistical analyses included frequencies, means and percentages. Chi square and t tests were conducted. The 254 participants were ages 18-65+ years, predominantly white, college educated with annual incomes above $50,000. Sources of nutrition knowledge ranged from a high of web sites (65 %) to a low of registered dietitians (9 %). Macronutrient restrictions reported for dieting were carbohydrates 77 %, fats 40 % and protein 19 %. The >30 age group was more likely to have: decreased amount of food intake P = .001), reducing overall calories (P = .047), skipping meals (P = .006) or trying commercial programs (P = .011). There was nothing of significance for those <30. Among all respondents, interest in gender-specific programs was compared with these variables: current weight satisfaction (P = .032), education (P = .008), income (P = . 006) and BMI (P = .004). Men who were dissatisfied with their weight were most likely to be interested in a gender-specific weight control program, especially those over age 30 years. Further research should address whether offering male-specific diet programs would offer incentive and motivation for males to lose and maintain weight loss. PMID:26758439

    Viral hepatitis is responsible for great health, social and economic burden both globally and in the UK. This study aimed to assess the research funding awarded to UK institutions for viral hepatitis research and the relationship of funded research to clinical and public health burden of viral hepatitis. Databases and websites were systematically searched for information on infectious disease research studies funded for the period 1997–2010. Studies specifically related to viral hepatitis research were identified and categorized in terms of funding by pathogen, disease and by a research and development value chain describing the type of science. The overall data set included 6165 studies (total investment £2.6 billion) of which £76.9 million (3.0%) was directed towards viral hepatitis across 323 studies (5.2%). By pathogen, there were four studies specifically investigating hepatitis A (£3.8 million), 69 studies for hepatitis B (21.4%) with total investment of £14.7 million (19.1%) and 236 (73.1%) hepatitis C studies (£62.7 million, 81.5%). There were 4 studies investigating hepatitis G, and none specifying hepatitis D or E. By associated area, viral hepatitis and therapeutics research received £17.0 million, vaccinology £3.1 million and diagnostics £2.9 million. Preclinical research received £50.3 million (65.4%) across 173 studies, whilst implementation and operational research received £19.4 million (25.3%) across 128 studies. The UK is engaged in much hepatology research, but there are areas where the burden is great and may require greater focus, such as hepatitis E, development of a vaccine for hepatitis C, and further research into hepatitis-associated cancers. Private sector data, and funding information from other countries, would also be useful in priority setting. PMID:25146854

  6. LANL receiver system development

    1997-08-01

    The CALIOPE receiver system development at LANL is the story of two technologies. The first of these technologies consists of off-the-shelf mercury-cadmium-telluride (MCT) detectors and amplifiers. The vendor for this system is Kolmar Technologies. This system was fielded in the Tan Trailer I (TTI) in 1995 and will be referred to in this paper as GEN I. The second system consists of a MCT detector procured from Santa Barbara Research Center (SBRC) and an amplifier designed and built by LANL. This system was fielded in the Tan Trailer II (TTII) system at the NTS tests in 1996 and will be referred to as GEN II. The LANL CALIOPE experimental plan for 1996 was to improve the lidar system by progressing to a higher rep rate laser to perform many shots in a much shorter period of time. In keeping with this plan, the receiver team set a goal of developing a detector system that was background limited for the projected 100 nanosecond (ns) laser pulse. A set of detailed simulations of the DIAL lidar experiment was performed. From these runs, parameters such as optimal detector size, field of view of the receiver system, nominal laser return power, etc. were extracted. With this information, detector physics and amplifier electronic models were developed to obtain the required specifications for each of these components. These derived specs indicated that a substantial improvement over commercially available, off-the-shelf, amplifier and detector technologies would be needed to obtain the goals. To determine if the original GEN I detector was usable, the authors performed tests on a 100 micron square detector at cryogenic temperatures. The results of this test and others convinced them that an advanced detector was required. Eventually, a suitable detector was identified and a number of these single element detectors were procured from SBRC. These single element detectors were witness for the detector arrays built for another DOE project.

    An ultra-wideband (UWB) receiver utilizes a strobed input line with a sampler connected to an amplifier. In a differential configuration, .+-.UWB inputs are connected to separate antennas or to two halves of a dipole antenna. The two input lines include samplers which are commonly strobed by a gating pulse with a very low duty cycle. In a single ended configuration, only a single strobed input line and sampler is utilized. The samplers integrate, or average, up to 10,000 pulses to achieve high sensitivity and good rejection of uncorrelated signals.

    Objectives The objectives of this study were to estimate the point prevalence of sexually transmitted infection (STI) and to investigate the sexual practices and behaviours associated with STIs in a group of gay men, other men who have sex with men and transgender women (GMT) in the province of La Romana, Dominican Republic. Design A cross-sectional study of a convenience sample of GMT persons. Setting The study was conducted in the province of La Romana, Dominican Republic, in June–July 2013. Participants Out of 117 GMT persons screened, a total of 100 completed the study. Participants had to be at least 18 years of age, reside in La Romana and have had sex with another man in the preceding 12 months. All participants were interviewed and tested for STI. Primary outcome measure The main outcome of interest was the detection of any STI (HIV, herpes simplex virus type 2 (HSV-2), syphilis, hepatitis B or C) by serology. Results Among 100 participants, the median age was 22 years (range 18–65). One-third had consumed illicit drugs the preceding year and only 43% consistently used condoms. Prevalence was 38% for HSV-2, 5% for HIV and 13% for syphilis. There were no cases of hepatitis B or C. Factors associated with the odds of a STI were age >22 years (OR=11.1, 95% CI 3.6 to 34.5), receptive anal intercourse (OR=4.2, 95% CI 1.3 to 13.6) and having ≥2 male sexual partners during the preceding month (OR=4, 95% CI 1.3 to 12.5). Conclusions In this group of GMT persons, seroprevalence of STI was high, and a number of risk behaviours were associated with STI. These preliminary data will help inform policy and programmes to prevent HIV/STI in GMT persons in the region. PMID:25926151

    SUMMARY We report the first population-based case-control study on acute hepatitis B in a very low-incidence country. A case was a Netherlands resident, notified between May 1999 and July 2000 with symptoms and serology compatible with acute hepatitis B. Population controls were randomly selected, with oversampling from men and persons aged 20–39 years. Risk factors were studied using logistical regression, distinguishing confounders and mediators through hierarchical analysis. Participants were 120 cases and 3948 controls. The risk of acute hepatitis B was increased in men who have sex with men, with reporting to have had more than two partners in the past 6 months the only significant risk. In children, adult females and heterosexual males, having parents born in a hepatitis B endemic country was a significant risk. For adult females and heterosexual males, this was largely explained by having a foreign partner. For children this was partly explained by parenteral exposures abroad. PMID:17407622

    The Centers for Disease Control and Prevention recommends integrating viral hepatitis prevention services with services for adults evaluated for sexually transmitted diseases (STDs). The Denver Public Health STD clinic began hepatitis B vaccination in 1999, hepatitis C virus (HCV) antibody (anti-HCV) testing in 2000, and hepatitis A vaccination in 2002. Rapid human immunodeficiency virus (HIV) testing began in late 2004. Hepatitis B vaccinations peaked in 2003 (31/100 client visits) when a full-time nurse was hired to vaccinate and eligibility was expanded. The proportion of clients documented to have received their anti-HCV test results declined from an average of 71% in 2000-2003 to 22% in 2004-2005, coinciding with the introduction of rapid HIV testing. Viral hepatitis prevention services can be incorporated into a busy STD clinic if staff and resources are available. Rapid HIV testing may be associated with lower receipt of anti-HCV test results.

    Northern Video Graphics, Inc. developed a low-cost satellite receiving system for users such as independent meteorologists, agribusiness firms, small airports or flying clubs, marine vessels and small TV stations. Called Video Fax, it is designed for use with certain satellites; the GOES (Geostationary Operational Environmental Satellite) spacecraft operated by the National Oceanic and Atmospheric Administration, the European Space Agency's Meteosat and Japan's Geostationary Meteorological Satellite. By dictum of the World Meteorological Organization, signals from satellites are available to anyone without cost so the Video Fax user can acquire signals directly from the satellite and cut out the middle man, enabling savings. Unit sells for about one-fifth the cost of the equipment used by TV stations. It consists of a two-meter antenna; a receiver; a microprocessor-controlled display computer; and a video monitor. Computer stores data from the satellites and converts it to an image which is displayed on the monitor. Weather map can be preserved as signal data on tape, or it can be stored in a video cassette as a permanent image.

    Aim: The aim of this study was to review our experience with gestations in autoimmune hepatitis patients. Background: There are only limited data describing pregnancy in patients with autoimmune hepatitis. Patients and methods: Retrospective analysis of pregnancies with autoimmune hepatitis followed in Centro Hospitalar do Porto, Portugal in the last ten years. Results: We reported nine pregnancies in seven patients with autoimmune hepatitis. Two patients had documented liver cirrhosis prior to the pregnancy. In this study, 66.7% of patients were treated with azathioprine and 88.9% with prednisolone. Clinical improvements were observed in 11.1% of pregnancies and 22.2% exacerbations were diagnosed. There were six live births and two preterm deliveries (preterm delivery rate of 33%). We also report three first trimester miscarriages (early gestation miscarriage rate of 33%). There were no neonatal or maternal deaths. Conclusion: The favorable obstetric outcome is a realistic expectation in patients with autoimmune hepatitis. Tight monitoring and control of asymptomatic and unpredictable exacerbations, which are unrelated to the severity of the underlying disease, are essential to the prognosis of the current pregnancy.

    Hepatic hemangiomas are benign tumors of the liver consisting of clusters of blood-filled cavities, lined by endothelial cells, fed by the hepatic artery. The vast majority of HH are asymptomatic, most often being discovered incidentally during imaging investigations for various unrelated pathologies. Typical hemangiomas, the so-called capillary hemangiomas, range from a few mm to 3 cm, do not increase in size over time and therefore are unlikely to generate future symptomatology. Small (mm-3 cm) and medium (3 cm-10 cm) hemangiomas are well-defined lesions, requiring no active treatment beside regular follow-ups. However, the so-called giant liver hemangiomas, of up to 10 cm (most commonly) and even 20+ cm in size (according to occasional reports) can, and usually will develop symptoms and complications that require prompt surgical intervention or other kind of therapy. HH belong to the class of hepatic “incidentalomas”, so-called because they are diagnosed incidentally, on imaging studies performed as routine examinations or for other reasons than the evaluation of a possible liver mass. Less than half of HH present with overt clinical symptoms, consisting, most often, of upper abdominal pain (this is usually the case for large lesions, which cause the distension of Glisson’s capsule). Hepatic hemangiomas require a careful diagnosis to differentiate from other focal hepatic lesions, co-occurring diagnoses are also possible. PMID:26361504

    Primary hepatic angiosarcoma is a rare, aggressive tumor; composed of spindle or pleomorphic cells that line, or grow into, the lumina of pre-existing vascular spaces like sinusoids and terminal hepatic venules; with only about 200 cases diagnosed annually worldwide but it is the most common primary malignant mesenchymal tumor of the liver in adults and accounts for 2% of all primary hepatic malignancies. HAS occurs in association with known chemical carcinogens, but 75% of the tumors have no known etiology. Patients present with vague symptoms like abdominal pain, weight loss, fatigue or an abdominal mass. Hepatic angiosarcoma is usually multicentric and involves both lobes, entire liver may also found to be involved. CD31 is the most reliable marker. These tumors lack specific features on imaging, so, pathological diagnosis is necessary. There are no established treatment guidelines because of low frequency and aggressive nature of tumor, chemotherapy is only palliative, liver resection is indicated for solitary mass and liver transplant is contraindicated. The aim of this article is to comprehensively review all the available literature and to present detailed information and an update on primary hepatic angiosarcoma. PMID:26008857

    Estimated number of those with osteoporosis was about 12,800,000, and about 23%, 3,000,000 were male osteoporosis in Japan. Incidence of hip, vertebral, distal radius, and proximal humeral fracture in men was half of that in women. Lifetime risk of hip fracture was 5.6% in men. Risk factors for osteoporotic fracture in men were low bone mineral density(BMD), previous fracture, low body mass index, smoking, family history of fracture, glucocorticoid use and others. For osteoporotic fractures, the fracture risk in smokers was significantly higher in men than in women. There was no differences in fracture risks by BMD, previous fracture, glucocorticoid use, and family fracture history between men and women. PMID:27346311

    A broad definition of men's reproductive and sexual health (MRSH) includes medical (pathophysiological) matters such as sexually transmitted infections (STIs), developmental anomalies, malignancy, trauma, and infertility. It also includes psychosocial concerns: sexuality, contraception, disease prophylaxis, developmental and lifecycle issues, tobacco and drug use, sexual identity and orientation, and partnership issues. College men, of whom a large majority are sexually active, have a range of MRSH needs, including some that are particular to their age and social environment. To reach men effectively requires approaches that are somewhat different from those used with women. Clinicians in college health services are in an excellent position to help young men recognize the importance of reproductive health and sexual responsibility. College health services therefore should offer men screening; clinical diagnosis and treatment for MRSH conditions; and information, education, and counseling services, in a manner designed to meet their unique needs.

  6. Digital Receiver Phase Meter

    Marcin, Martin; Abramovici, Alexander

    2008-01-01

    The software of a commercially available digital radio receiver has been modified to make the receiver function as a two-channel low-noise phase meter. This phase meter is a prototype in the continuing development of a phase meter for a system in which radiofrequency (RF) signals in the two channels would be outputs of a spaceborne heterodyne laser interferometer for detecting gravitational waves. The frequencies of the signals could include a common Doppler-shift component of as much as 15 MHz. The phase meter is required to measure the relative phases of the signals in the two channels at a sampling rate of 10 Hz at a root power spectral density <5 microcycle/(Hz)1/2 and to be capable of determining the power spectral density of the phase difference over the frequency range from 1 mHz to 1 Hz. Such a phase meter could also be used on Earth to perform similar measurements in laser metrology of moving bodies. To illustrate part of the principle of operation of the phase meter, the figure includes a simplified block diagram of a basic singlechannel digital receiver. The input RF signal is first fed to the input terminal of an analog-to-digital converter (ADC). To prevent aliasing errors in the ADC, the sampling rate must be at least twice the input signal frequency. The sampling rate of the ADC is governed by a sampling clock, which also drives a digital local oscillator (DLO), which is a direct digital frequency synthesizer. The DLO produces samples of sine and cosine signals at a programmed tuning frequency. The sine and cosine samples are mixed with (that is, multiplied by) the samples from the ADC, then low-pass filtered to obtain in-phase (I) and quadrature (Q) signal components. A digital signal processor (DSP) computes the ratio between the Q and I components, computes the phase of the RF signal (relative to that of the DLO signal) as the arctangent of this ratio, and then averages successive such phase values over a time interval specified by the user.

    The purpose of this study was to describe and compare the free-speed gait characteristics of healthy young men with those of healthy elderly men. Data collection consisted of high-speed cinematography resulting in synchronized front and side views of 24 healthy male volunteers, 12 between 20 and 32 years of age and 12 between 60 and 74 years of age. Young men were recruited to match the elderly men on the basis of right-leg length. Each subject participated in three filmed trials of free-speed ambulation down a 14-m walkway. The processed film was analyzed for eight gait characteristics. Differences in characteristics between the two groups were examined using a correlated t test (p less than .01). No significant differences were observed between the groups for step and stride length, velocity, ankle range of motion, vertical and horizontal excursions of the center of gravity, and pelvic obliquity; however, the younger men demonstrated a significantly larger stride width than the elderly men (p less than .01). The results suggest that the two populations of healthy adult men have similar gait characteristics. PMID:2913584

    Chronic hepatitis B (CH-B) is common among HIV-infected individuals and increases liver-related mortality in the absence of highly active antiretroviral therapy (HAART). The impact of CH-B on long-term HAART outcomes has not been fully characterized. Methods To address this question, HAART initiators enrolled in the Multicenter AIDS Cohort Study (MACS) were retrospectively analyzed. Subjects were classified by hepatitis B category based on serology at the time of HAART initiation. The association of CH-B with mortality, AIDS defining illnesses, CD4 rise, and HIV suppression was assessed using regression analysis. Results Of 816 men followed for a median of 7 years on HAART, 350 were never HBV infected, 357 had past infection, 45 had CH-B, and 64 were only core-antibody positive. Despite HAART, AIDS-related mortality was the most common cause of death (8.3/1000 person-years (PYs)). It was highest in those with CH-B (17/1000 PYs, 95% CI 7.3, 42) and lowest among never HBV infected (2.9/1000 PYs, 95% CI 1.4, 6.4). In a multivariable model, patients with CH-B had a 2.7-fold higher incidence of AIDS-related mortality compared to those never infected (P=0.08). Non-AIDS-related mortality was also highest among those with CH-B (22/1000 PYs), primarily due to liver disease (compared to never infected, adjusted HR 4.1, p=0.04). There was no significant difference in AIDS defining events, HIV RNA suppression, and CD4 increase. Conclusion In HIV-infected patients receiving long-term HAART, HBV status did not influence HIV suppression or CD4 increase. However, mortality was highest among those with CH-B and was mostly due to liver disease despite HBV-active HAART. PMID:19550291

    A plurality of heat pipes in a shell receive concentrated solar energy and transfer the energy to a heat activated system. To provide for even distribution of the energy despite uneven impingement of solar energy on the heat pipes, absence of solar energy at times, or failure of one or more of the heat pipes, energy storage means are disposed on the heat pipes which extend through a heat pipe thermal coupling means into the heat activated device. To enhance energy transfer to the heat activated device, the heat pipe coupling cavity means may be provided with extensions into the device. For use with a Stirling engine having passages for working gas, heat transfer members may be positioned to contact the gas and the heat pipes. The shell may be divided into sections by transverse walls. To prevent cavity working fluid from collecting in the extensions, a porous body is positioned in the cavity.

    The quadrivalent meningococcal conjugate vaccine (MenACWY-CRM) has been introduced for military recruits in Korea since 2012. This study was performed to evaluate the immunogenicity of MenACWY-CRM in Korean military recruits. In addition, the influence of tetanus-diphtheria toxoids (Td) vaccination on the vaccine response to MenACWY-CRM was analyzed. A total of 75 military recruits were enrolled. Among them, 18 received a dose of MenACWY-CRM only (group 1), and 57 received Td three days before MenACWY-CRM immunization (group 2). The immunogenicity of MenACWY-CRM was compared between the two groups. The serum bactericidal activity with baby rabbit complement was measured before and three weeks after immunization against serogroups A, C, W-135, and Y. The geometric mean titers (GMTs) against four serogroups were significantly increased in both groups after immunization. Compared to group 2, group 1 exhibited significantly higher vaccine responses in several aspects: post-immune GMTs against serogroup A and C, seroresponse rates against serogroup A, and a fold increases of titers against serogroup A, C, and Y. MenACWY-CRM was immunogenic against all vaccine-serogroups in Korean military recruits. Vaccine response to MenACWY-CRM was influenced by Td administered three days earlier. PMID:27593883

    Background The hepatitis B, hepatitis C, human immunodeficiency viruses and Treponema pallidum are important causes of infectious diseases concern to public health. Methods Between 2010 and 2014, we used an automated chemiluminescence microparticle immunoassay to detect the hepatitis B, hepatitis C, and human immunodeficiency viruses as well as Treponema pallidum (the rapid plasma regain test was used in 2010–2011). Positive human immunodeficiency virus tests were confirmed via western blotting. Results Among 416,130 subjects, the seroprevalences for hepatitis B virus, hepatitis C virus, human immunodeficiency virus, and Treponema pallidum were 5.72%, 1.23%, 0.196%, and 0.76%, respectively. Among 671 patients with positive human immunodeficiency virus results, 392 cases were confirmed via western blotting. Hepatitis B and human immunodeficiency virus infections were more frequent in men (7.78% and 0.26%, respectively) than in women (4.45% and 0.021%, respectively). The hepatitis B and C virus seroprevalences decreased from 6.21% and 1.58%, respectively, in 2010, to 5.37% and 0.988%, respectively, in 2014. The human immunodeficiency virus seroprevalence increased from 0.04% in 2010 to 0.17% in 2014, and was elevated in the Infectious Disease (2.65%), Emergency (1.71%), and Dermatology and Sexually Transmitted Diseases (1.12%) departments. The specificity of the human immunodeficiency virus screening was 71.4%. The false positive rates for the Treponema pallidum screening tests increased in patients who were 60–70 years old. The co-infection rates for the hepatitis C and human immunodeficiency viruses were 0.47% in hepatitis C virus-positive patients and 7.33% in human immunodeficiency virus-positive patients. Conclusions During 2010–2014, hepatitis B virus and human immunodeficiency virus infections were more frequent among men at our institution. Although the seroprevalences of hepatitis B and C viruses decreased, the seroprevalence of human immunodeficiency

    Response-guided therapy is of limited use in developing countries because hepatitis C virus RNA detection by sensitive molecular methods is time- and labor-consuming and expensive. We evaluated early predictive efficacy of serum hepatitis C virus core antigen kinetics on sustained virologic response in patients with genotype 1 hepatitis C virus during pegylated interferon plus ribavirin treatment. For 478 patients recruited, hepatitis C virus RNAs were detected at baseline, and at weeks 4, 12, 24, 48, and 72 using Cobas TaqMan. Architect hepatitis C virus core antigen was performed at baseline, and weeks 4 and 12. Predictive values of hepatitis C virus core antigen on sustained virologic response were compared to hepatitis C virus RNA. In the first 12 weeks after treatment initiation the dynamic patterns of serum hepatitis C virus core antigen and hepatitis C virus RNA levels were similar in sustained virologic response, relapse, and null response patients groups. Although areas under the receiver operating characteristics curves of hepatitis C virus core antigen were lower than those of hepatitis C virus RNA at the same time points, modeling analysis showed that undetectable hepatitis C virus core antigen (rapid virological response based on hepatitis C virus core antigen) had similar positive predictive value on sustained virologic response to hepatitis C virus RNA at week 4 (90.4% vs 93.3%), and hepatitis C virus core antigen decrease greater than 1log10IU/mL (early virological response based on hepatitis C virus core antigen) had similar negative predictive value to hepatitis C virus RNA at week 12 (94.1% vs 95.2%). Analysis on the validation group demonstrated a positive predictive value of 97.5% in rapid virological response based on hepatitis C virus core antigen and a negative predictive value of 100% in early virological response based on hepatitis C virus core antigen. In conclusion, hepatitis C virus core antigen is comparable to hepatitis C virus RNA in

    A study has been conducted to generate and evaluate advanced solar heat receiver concepts suitable for orbital application with Brayton and Stirling engine cycles in the 7-kW size range. The generated receiver designs have thermal storage capability (to enable power production during the substantial eclipse period which accompanies typical orbits) and are lighter and smaller than state-of-the-art systems, such as the Brayton solar receiver being designed and developed by AiResearch for the NASA Space Station. Two receiver concepts have been developed in detail: a packed bed receiver and a heat pipe receiver. The packed bed receiver is appropriate for a Brayton engine; the heat pipe receiver is applicable for either a Brayton or Stirling engine. The thermal storage for both concepts is provided by the melting and freezing of a salt. Both receiver concepts offer substantial improvements in size and weight compared to baseline receivers.

    Background Hemophilic patients require long-life intravenous infusion of factor concentrates to treat bleedings. This could increase the risk of transmission of blood-borne infections like hepatitis C. Objectives The current study was aimed at investigating the immunity status against hepatitis A in hemophilic patients in south Khorasan and evaluating the necessity of hepatitis A vaccination for this population. Patients and Methods A cross-sectional descriptive study was conducted between 2014 and 2015 on all hemophilic patients of south Khorasan province, Iran (n = 108) for anti-HAV total, anti- HCV, HBs-Ag, anti-HIV, and anti-HTLV-I /II. Note that no one had already received a hepatitis A vaccine. Results As our results show, 77.8% of the participants (59% under 20 and 88.4% above 20 years old) were seropositive for anti-HAV total; 20.4% and 2.8% (three patients) of the cases were anti-HCV positive and anti-HTLV-1 positive, respectively, while none of the subjects were HBS-Ag or HIV-Ab positive. Seventeen of the patients (15.75%) showed a co-infection of HAV with HCV, and five HCV-infected patients (22.73%) had no immunity against hepatitis A. There was a significant relationship between age, rural life, and anti-HAV positive state in our patients (P < 0.001). No significant relationship between positive anti-HAV status and sex (P = 0.16), severity of hemophilia (P = 0.23), and infection with HIV, HCV, HTLV-1, and hepatitis B (P > 0.05) was detected. Conclusions More than 40% of the hemophilic patients under 20 years of age in the present study had no immunity against hepatitis A, and 23% of hepatitis C patients had not had a hepatitis A co-infection yet. Since hepatitis A can show a fulminant course in hepatitis C patients, vaccination against hepatitis A seems necessary in hemophilic patients in the region. PMID:27257430

    In the present study the frequencies of immunity against hepatitis B (HB) and of potentially contaminating accidents among medical students of a Brazilian public university were evaluated. Of all the 400 students who should have been immunized, 303 (75.7%), 66.3% of whom were women, answered an anonymous, self-administered questionnaire. Serum anti-HBs were determined in 205 of them and titers ≥ 10 UI/L were considered to be protective. A total of 86.8% of students had received three doses of HB vaccine. The frequency of immunity among women (96.4%) was higher (p = 0.04) than that among men (87.7%). Among those who did not have immunity, 12/13 (92.3%) had been vaccinated before entering medical school. Only 11% of the students with complete vaccination had previously verified serological response to the vaccine. A total of 23.6% reported having been somehow exposed to blood or secretions. Among final-year students, this frequency was 45.0%, being similar among men (47.8%) and women (43.2%). Of all these accidents, 57.7% were due to body fluids coming in contact with mucosa and 42.3% due to cut and puncture accidents. The results from this study show that: 1) the frequency of immunity against HB is high among the evaluated medical students, although verification of response to vaccination is not a concern for them; 2) anti-HBs titers should be verified after complete vaccination and on a regular basis, especially by men; and 3) the frequency of potentially contaminating accidents is high.

    A micro-complement fixation test was modified for the detection of low-titred antibodies to protamines. Specific immunological reactions with salmon protamine were found with some sera obtained from infertile men and vasectomized men and monkeys. The possibilities that allergic reactions, observed in patients receiving salmon protamine, result from immunity to the fish protamine and from immunological cross-reaction between human and salmon protamines (in cases where auto-immunity to human protamine has developed prior to the administration of fish protamine) are discussed.

    We aimed to elucidate the mechanism underlying the anti-dyslipidemic effect of compound-T3, a farnesoid X receptor antagonist, by investigating its effects on hepatic lipid metabolism in non-human primates. We administered lipid-lowering drugs for 7 days to cynomolgus monkeys receiving a high-fat diet, and subsequently measured the levels of lipid parameters in plasma, feces, and hepatic tissue fluids. Compound-T3 (0.3 and 3mg/kg p.o.) significantly decreased the plasma levels of non-high-density lipoprotein (non-HDL) cholesterol and apolipoprotein B in a dose-dependent manner. It also decreased the mRNA levels of hepatic small heterodimer partner-1, induced the mRNA expression of hepatic cholesterol 7α-hydroxylase, reduced hepatic cholesterol and triglyceride levels, increased fecal bile acid excretion, and upregulated the expression of hepatic low-density lipoprotein (LDL) receptor. Furthermore, compound-T3 significantly increased plasma HDL cholesterol and apolipoprotein A-I levels. The mRNA expression levels of hepatic apolipoprotein A-I tended to increase after compound-T3 treatment. Compound-T3 also induced accumulation of hepatic bile acids and decreased the mRNA expression levels of the hepatic bile acid export pump. The effects of cholestyramine (300mg/kg p.o.) on the plasma and hepatic lipid parameters were similar to those of compound-T3, and it increased fecal bile acid levels without causing accumulation of hepatic bile acids. These findings suggest that LDL receptor-mediated hepatic LDL incorporation due to cholesterol catabolism catalyzed by cholesterol 7α-hydroxylase decreases plasma non-HDL cholesterol levels. Upregulation of hepatic apolipoprotein A-I mRNA expression may partially contribute to the increase in HDL cholesterol levels mediated by compound-T3. PMID:24361308

  2. ADMX Receiver and Analysis

    2016-03-01

    ADMX looks for the excess radiation deposited into a cavity from the conversion of a dark matter axion into a microwave photon. The sensitivity of the experiment increases by reducing the background thermal noise and minimizing the electronic noise of the readout system. The axion masses that the experiment can detect are determined by the resonant frequency of the cavity mode of interest, which is tuned using a two rod configuration. One can also increase the search rate by measuring the output from two cavity modes at once, which requires two separate readout schemes. I will discuss the ADMX dual-channel receiver which has been upgraded to have near quantum-limited sensitivity on both channels, and describe how the correct modes are verified, using simulations, in the presence of dense electromagnetic structure. I conclude by describing upgrades to the ADMX analysis which allow for real-time exclusion limits.

  3. Anchorage Receives Record Snowfall

    2002-01-01

    The forecast called for flurries, but the snow accumulated on the ground in Anchorage, Alaska, at the rate of 2 inches per hour (5 cm per hour) for much of Saturday, March 16, 2002. By the time the winter storm passed on Sunday afternoon, Anchorage had received 28.6 inches (72.6 cm) of snow, surpassing by far the previous record of 15.6 inches (39.6 cm) set on December 29, 1955. Flights were canceled and schools were closed as a result of the storm. This true-color image of Alaska was acquired by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS), flying aboard the OrbView-2 satellite, on March 18. It appears another large, low-pressure system is heading toward the Anchorage region, which could bring substantially more snowfall. The low-pressure system can be identified by the characteristic spiral pattern of clouds located off Alaska's southwestern coast in this scene.

    The availability of longitudinal data collected prospectively from 1998 to 2011 at federally funded US hemophilia treatment centers provided an opportunity to construct a descriptive analysis of how outcomes of men with severe hemophilia have been altered by the incremental advances and setbacks in hemophilia care in the last 50 years in the United States. This surveillance collaboration with the US Centers for Disease Control and Prevention assembled the largest uniformly examined population with severe hemophilia (n = 4899 men with severe factor VIII and IX deficiency). To address the heterogeneity of this population, 4 successive birth cohorts, differentially affected by eras of hemophilia care, were examined separately in regard to demographics, complications of hemophilia and its treatment, and mortality. Severely affected men in each birth cohort were compared also with the corresponding mild hemophilia birth cohorts (n = 2587 men total) to control for outcomes that might be attributable to aging and environment independent of severely defective hemostasis. The analysis demonstrates improving access to standard of care therapy, correlating the proportion of men on prophylactic factor replacement and reduced bleeding frequency for the youngest men. Frequent bleeding persisted in one third to one half of men across all ages, however, and the disability gap between severe and mild hemophilia did not narrow. The greatest cause of death was liver failure, but attempted anti-hepatitis C virus therapy and cure were low. The study suggests a continued need for national surveillance to monitor and inform hemophilia interventions and outcomes. PMID:26983851

    Purpose: To evaluate retrospectively the biochemical outcomes of young men treated with low-dose-rate brachytherapy for prostate cancer. Methods and Materials: From 1990 to 2005, 1,665 men with clinically localized prostate cancer were treated with low-dose-rate brachytherapy {+-} hormone therapy (HT) {+-} external beam radiotherapy and underwent {>=}2 years of follow-up. Patients were stratified on the basis of age: {<=}60 (n = 378) and >60 years (n = 1,287). Biochemical failure was defined as a prostate-specific antigen (PSA) nadir plus 2 ng/mL. Univariate and multivariate analyses were used to determine the association of variables with freedom from biochemical failure (FFbF). Results: Median follow-up was 68 months (range, 24-180) for men {<=}60 years and 66 months (range, 24-200) for men >60. For the entire group, the actuarial 5- and 8-year FFbF rates were 94% and 88%, respectively. Men {<=}60 demonstrated similar 5- and 8-year FFbF (95% and 92%) compared with men >60 (93% and 87%; p = 0.071). A larger percent of young patients presented with low-risk disease; lower clinical stage, Gleason score (GS), and pretreatment PSA values; were treated after 1997; did not receive any HT; and had a high biologic effective dose (BED) of radiation (all ps <0.001). On multivariate analysis, PSA (p = 0.001), GS (p = 0.005), and BED (p < 0.001) were significantly associated with FFbF, but age was not (p = 0.665). Conclusion: Young men achieve excellent 5- and 8-year biochemical control rates that are comparable to those of older men after prostate brachytherapy. Young age should not be a deterrent when considering brachytherapy as a primary treatment option for clinically localized prostate cancer.

  7. Occupational hepatic disorders in Korea.

    Occupational hepatic disorders are classified into toxic hepatitis, viral hepatitis, and chemical-induced malignancy in Korea. Toxic hepatitis cases were reported in workers who were exposed to dimethylformamide, dimethylacetamide, or trichloroethylene. Pre-placement medical examination and regular follow-up are necessary to prevent the development of toxic hepatitis. Viral hepatitis was chiefly reported among health care workers such as doctors, nurses and clinical pathology technicians who could easily be exposed to blood. Preventive measures for these groups therefore include vaccination and serum monitoring programs. Hepatic angiosarcoma caused by vinyl chloride monomer (VCM) exposure is a very well known occupational disease and it has not been officially reported in Korea yet. Some cases of hepatocellular carcinoma were legally approved for compensation as an occupational disease largely by overwork and stress, but not supported by enough scientific evidence. Effort to find the evidence of its causal relationship is needed. PMID:21258588

    Purpose. This study evaluates the influence of transcatheter arterial infusion with heated saline on hepatic arterial and portal venous blood flows to tumor and normal hepatic tissues in a rabbit VX2 tumor model. Methods. All animal experiments were approved by the institutional animal care and use committee. Twenty rabbits with VX2 liver tumors were divided into the following two groups: (a) the treated group (n = 10), which received a 60 mL transarterial injection of 60 Degree-Sign C saline via the hepatic artery; (b) the control group (n = 10), which received a 60 mL injection of 37 Degree-Sign C saline via the hepatic artery. Using ultrasonography, the blood flows in both the portal vein and hepatic artery were measured, and the changes in the hemodynamic indices were recorded before and immediately after the injection. The changes in the tumor and normal liver tissues of the two groups were histopathologically examined by hematoxylin and eosin staining after the injection. Results. After the transcatheter arterial heated infusion, there was a decrease in the hepatic arterial blood flow to the tumor tissue, a significant decrease in the hepatic artery mean velocity (P < 0.05), and a significant increase in the resistance index (P < 0.05). On hematoxylin and eosin staining, there were no obvious signs of tissue destruction in the normal liver tissue or the tumor tissue after heated perfusion, and coagulated blood plasma was observed in the cavities of intratumoral blood vessels in the treated group. Conclusions. The changes in tumor blood flow in the rabbit VX2 tumor model were presumably caused by microthrombi in the tumor vessels, and the portal vein likely mediated the heat loss in normal liver tissue during the transarterial heated infusion.

    Co-infection with the hepatitis C virus (HCV) and/or hepatitis B virus (HBV) influences the morbidity and mortality of patients with HIV. A cross sectional analysis was of 11,032 HIV-infected patients enrolled in the Integrated HIV Care Program from May 2005 to April 2012 and Epi-info 3.5 was used to determine the serological prevalence of chronic hepatitis B and hepatitis C. The mean ± standard deviation age of patients was 36 ± 8.4 years (adult cohort) and 7 ± 3 years (paediatric cohort). The sero prevalence of hepatitis B surface antigen, hepatitis C (anti HCV antibodies) and triple infection are 8.7%, 5.3% and 0.35%, respectively. Men who have sex with men are at the highest risk of being co-infected with hepatitis B while intravenous drug users are at the highest risk of being co-infected with hepatitis C. It is important to screen for hepatitis B and C in HIV infected people in order to provide quality care for HIV patients with co-infection. PMID:23800421

    This study compares prevalence rates of psychoactive substances use in two samples of young men who were called to the Military Service Medical Examination, in Buenos Aires city, in two different periods of time: in 1992, a thousand nine hundred eighty men were included, and in 1994, a thousand four hundred eighty men answered the questionnaire. Same methodological procedures were applied in both periods. Marihuana consumption level showed no changes; little decrease were observed in cocaine declared consumption; alcohol abuse level also declined. Nevertheless, more than 3 of each ten young men recognized an alcoholic ingestion of more of 100 cc of absolute alcohol during the past 30 days before in both studies. Relations between use of legal and illegal psychoactive substances are explored in the 1994 sample. PMID:8762704

    Objectives The HEPAIG study was conducted to better understand Hepatitis C virus (HCV) transmission among human immuno-deficiency (HIV)-infected men who have sex with men (MSM) and assess incidence of HCV infection among this population in France. Methods and Results Acute HCV infection defined by anti-HCV or HCV ribonucleic acid (RNA) positivity within one year of documented anti-HCV negativity was notified among HIV-infected MSM followed up in HIV/AIDS clinics from a nationwide sampling frame. HIV and HCV infection characteristics, HCV potential exposures and sexual behaviour were collected by the physicians and via self-administered questionnaires. Phylogenetic analysis of the HCV-NS5B region was conducted. HCV incidence was 48/10 000 [95% Confidence Interval (CI):43–54] and 36/10 000 [95% CI: 30–42] in 2006 and 2007, respectively. Among the 80 men enrolled (median age: 40 years), 55% were HIV-diagnosed before 2000, 56% had at least one sexually transmitted infection in the year before HCV diagnosis; 55% were HCV-infected with genotype 4 (15 men in one 4d-cluster), 32.5% with genotype 1 (three 1a-clusters); five men were HCV re-infected; in the six-month preceding HCV diagnosis, 92% reported having casual sexual partners sought online (75.5%) and at sex venues (79%), unprotected anal sex (90%) and fisting (65%); using recreational drugs (62%) and bleeding during sex (55%). Conclusions This study emphasizes the role of multiple unprotected sexual practices and recreational drugs use during sex in the HCV emergence in HIV-infected MSM. It becomes essential to adapt prevention strategies and inform HIV-infected MSM with recent acute HCV infection on risk of re-infection and on risk-reduction strategies. PMID:22216248

    The liver normally produces a large amount of lymph. It is estimated that between 25% and 50% of the lymph received by the thoracic duct comes from the liver. In normal conditions, hepatic lymphatics are not depicted on cross-sectional imaging. They are divided in lymphatics of deep system (lymphatics following the hepatic veins and the portal tract) and those of superficial system (convex surface and inferior surface). A variety of diseases may affect hepatic lymphatics and in general they manifest as lymphedema, lymphatic mass, or cystic lesions. Abnormal distended lymphatics are especially seen in periportal spaces as linear hypoattenuations on CT or strong linear hyperintensities on heavily T2-weighted MR imaging. Lymphatic tumor spread as in lymphoma and lymphangitic carcinomatosis manifests as periportal masses and regional lymph node enlargement. Lymphatic disruption after trauma or surgery is depicted as perihepatic fluid collections of lymph (lymphocele). Lymphatic malformation such as lymphangioma is seen on imaging as cystic spaces of variable size. PMID:25579171

    With most couples in China currently bearing only 1-2 children, the average couple must practice family planning for more than 20-30 years. An extremely high level of cooperation is therefore required between husband and wife to realize this level of fertility. The Vice-Chairman of the Standing Committee of the National People's Congress stresses that men should take a greater role in family planning. Women, like men, work to contribute to family income, but they also become pregnant, give birth, breastfeed, and rear children. Men should really share some responsibilities of family planning to alleviate some degree of burden borne by women. In particular, men could opt to be sexually sterilized to eliminate the potential for any further unwanted fertility as a result of their continued sexual intercourse. The process of male sterilization is easier and safer than female sterilization with the Li method of male sterilization requiring only an injection into the seminal passage to prevent the further emission of semen. The vice-chairman notes that more than 15 million men voluntarily underwent male sterilization in Sichuan province, thus accounting for half of male sterilization cases in the world. Not everyone, however, should accept sterilization, but efforts could nonetheless be made to encourage men to accept greater responsibility for the control of their fertility. PMID:12287782

    This paper reports the epidemiology of hospital-diagnosed acute viral hepatitis in U.S. Air Force personnel from 1980-89. First hospitalizations for viral hepatitis generally declined, ranging from 24.6 to 47.2 per 100,000 personnel. Hepatitis rates were higher among men, (RR = 1.3; 95% C.I., 1.1-1.5) and higher among blacks, compared to whites (RR = 1.4; 95% C.I., 1.3-1.6). Analysis of risk associated with various occupations demonstrated an increased risk of viral hepatitis for procedurally oriented medical personnel (physicians, clinical nurses, dentists) when compared to all other occupations (RR = 1.5; 95% C.I., 1.1-1.9). Pilots and navigators demonstrated a decreased risk of acute viral hepatitis. Members hospitalized for hepatitis B had a prior or concurrent diagnosis for sexually transmitted disease in 37% of cases; for drug abuse, 32% of cases. Serum samples from 332 individuals demonstrated that hepatitis A had the highest rate of agreement (84%) between serology and hospital discharge diagnosis. Only 3% of individuals with the diagnosis of NANB hepatitis were positive for hepatitis C. PMID:8018082

    Viral hepatitis is a common problem in the incarcerated population. It causes significant morbidity and mortality, and incarcerated inmates receive their health care almost exclusively from corrections-based health systems. The seroprevalence of hepatitis B and C infections is increased in this population, and a number of risk factors for viral hepatitis are particularly common and infer higher risk among inmates, including injection drug use (IDU), high-risk sexual activity, and tattoos. IDU, in particular, has been identified as an important and common risk factor for viral hepatitis in inmates, and variable rates of IDU among inmates have been found to be the most important cause of the marked variability of seroprevalence rates for exposure to hepatitis C virus. A number of risk reduction and management strategies have been identified that can decrease transmission to other inmates. Prison-based hepatitis A and hepatitis B vaccination programs, needle exchange programs, methadone maintenance programs, risk education programs, and hepatitis C virus antiviral programs, for example, have been shown to be safe and effective risk reduction and management strategies. Preliminary studies have shown that these strategies are underutilized in the United States. Reasons for this phenomenon are multifactorial, involving financial as well as ethical and political considerations. Additional funding, research, and formal consideration / discussion of the complex issues involving viral hepatitis in the US incarcerated population are clearly important for the sake of inmates and the community at large. In this article, the published medical literature regarding this important topic is reviewed. PMID:19240708

    Dengue is an acute febrile illness resulting from infection by a flavivirus transmitted by the Aedes mosquito. It is characterized by bleeding manifestations and a plasma leak syndrome. Hepatic involvement in the form of elevation in transaminases is common. However, acute hepatic failure is uncommon. It is not known how the presence of an underlying chronic hepatitis or liver disease affects the likelihood of severity of hepatitis from dengue. The present report is of a 33-year-old man, a carrier of hepatitis B virus, who presented with fever, altered sensorium, thrombocytopenia, and coagulopathy. He was diagnosed to have developed acute hepatic failure due to dengue. The patient improved with supportive measures. PMID:21422600

    AIM: To describe spontaneous, or interferon (IFN)- or immunization-induced skin lesions in hepatitis B virus (HBV) infection. METHODS: A comprehensive literature search of all the papers presenting case reports of dermatological lesions in patients with chronic HBV infection was carried out. We included only patients with histologically proven skin lesions that appeared in the normal course of hepatitis B infection, or after immunization for hepatitis B or antiviral treatment. RESULTS: We found 44 papers on this topic, reporting 151 cases. About 2% of patients with hepatitis B infection, mainly men, presented with skin lesions. Among patients with chronic hepatitis B, vasculitis and essential mixed cryoglobulinemia seemed to be the most frequent skin lesion (53.3%), followed by papular changes, rashes and Gianotti-Crosti syndrome, skin carcinoma and Henoch-Schönlein purpura were rare. IFN treatment seemed to be effective against HBV-associated and immunoglobulin-complex-mediated disease (vasculitis). Two cutaneous lesions (lichen planus and granuloma annulare) were described after hepatitis B vaccination. Systemic lupus and lupus-like lesions were the most frequently encountered lesions after antiviral treatment. Immunosuppressive and steroid therapy ameliorates lichen planus lesions in 50% of cases. CONCLUSION: Vasculitis was the most frequent spontaneous skin lesion found in chronic hepatitis B. Lichen planus was most frequent after immunization and lupus/lupus-like lesions after IFN.

    Purpose To study time trends of antidepressant drug (AD) prescriptions in a geographically defined US population between 2005 and 2011 for men and women separately. Methods Using the Rochester Epidemiology Project medical records-linkage system, we identified all Olmsted County, MN residents who received AD outpatient prescriptions between 2005 and 2011 (seven years). We calculated the annual age-and sex-specific prevalence over seven years, and used generalized estimating equation models to test for time trends. Results The prevalence of subjects receiving at least one AD prescription was approximately two times higher in women than men consistently across the seven years of the study. The standardized annual prevalence increased from 10.8% in 2005 to 14.4% in 2011 overall, from 7.0% in 2005 to 9.9% in 2011 for men, and from 14.4% in 2005 to 18.6% in 2011 for women. The absolute percent increase was greater in women (4.2% vs. 2.9%; standardized); however, the relative percent increase was greater in men (41.4% vs. 29.2%; standardized). The relative percent increase was greater in the age group 65+ years for both men and women. Conclusions AD prescriptions are increasing over time, especially in the elderly. Women receive more AD prescriptions than men. However, the relative increase in AD prescriptions over time is greater in men than women. PMID:25113318

    Institute of Pediatric Gastroenterology is superspecialised referral institute for all Pediatric Gastroenterological diseases from all over the country and for adjoining countries. We have our data and experience on 10,500 cases of proven Hepatitis E (HEV) in Pediatric population. HEV is non-enveloped 27-30 nm diameter RNA virus, prototype for alpha-like supergroup of positive stranded RNA virus. Indian HEV strain has 97% nucleotide and 98% amino acid sequence identity with Chinese strains but much diversity with Mexican strain. More than 70% acute hepatitis occurring in Pediatric population in this subcontinent are caused by HEV and 80% of these are sporadic. 90% cases were enterically transmitted, spread primarily by fecally contaminated drinking water (70%) and by food (20%), in 9.5% case spread probably was because of person to person and household contact. We could demonstrate HEV in urine, respiratory secretions. Interestingly we found HEV in insects like Flies, Cockroaches, and also in engorged Bedbugs and in Mosquitoes, apart from briefly boiled Mussels, and partially cooked cockles. Maternal-neonatal transmission could be seen if mother had HEV infection in third trimester of pregnancy. In 5 cases we could demonstrate HEV in breast milk. By studying on 10 volunteers, 40% have anicteric form only accompanied by anorexia, epigastric pain. HEV appeared in serum before the icteric phase. Shedding of virus in stool starts before the icteric phase and continued during the high levels of abnormal ALT. Hepatitis IgG anti-HEV persist up to 4 years. In 5 cases we could establish Transfusion associated Hepatitis (TAH). No chronicity could be documented. 5% cases had fulminant viral Hepatitis (FVH)/Sub fulminant viral Hepatitis (SVH), alpha-interferon (IFN) has been proved beneficial in these cases, further use of intravenous PGEl could also be beneficial. Inadequate chlorination of drinking water was an important additional factor for causing epidemics. A free

    Spain has a medium endemicity of hepatitic C infection among central Europe countries and Italy. Prevalence of anti-HCV varies among regions and it ranges from 1.6 to 2.6%, which means that there may be between 480,000 and 760,000 people infected with hepatitis C virus in Spain. The prevalence is very low in people under 20 years of age and it increases from age 30 years. Prisoners and drug addicts have the highest infectious rates, between 40 and 98%. Some populations of immigrants also have a high prevalence of HCV infection, especially people from Asia and sub-Saharan countries, whereas people from Latin America have rates lower than those in the autochtones population. Spanish people with chronic hepatitis C were mainly infected via blood transfusions, IV drug use, or during some medical and surgical hospitalization. The reduction in the use of IV drugs and the programs of needle sharing, as well as the eradication of post-transfusional hepatitis, have led to a progressive reduction in the incidence of new infections (from 6.8 per 100,000 in-habitants in 1997 to 2.3 in 2003). Preliminary data suggest that an important rate of new hepatitis C cases owe to nosocomial transmission. Transmission is almost exclusively vertical in children. In spite of a two-third reduction of incident cases of hepatitis C in Spain in last few years, it is foreseeable that the number of patients with advanced HCV liver disease attended in the health-care system will increase in forthcoming years. This is due to the fact that many, still undiagnosed patients will be likely recognized for the first time as a result of some complication of the disease. All efforts to increase the screening of hidden cases of hepatitis C in primary health-care centers, allowing a prompt treatment before an advanced stage, will have a beneficial impact both in economic and social terms.

    In India, men who have sex with men (MSM) remain hidden because anal intercourse was criminalized and marriage socially required. We characterize HIV/STI prevalence among MSM in Tamil Nadu. Eligible participants were recruited using respondent-driven sampling in eight cities (n = 721). Median age was 28, 34% were married and 40% self-identified as homosexual. Median number of male partners in the prior year was 15; 45% reported any unprotected anal intercourse (UAI). HIV, herpes simplex virus-2 (HSV-2), chronic hepatitis B virus (HBV) and syphilis prevalence were 9, 26, 2 and 8%, respectively; among married men, all were higher: 14, 32, 3 and 11% (p < 0.01 for HIV and HSV-2). Less education, HSV-2, more male partners, UAI and not having a main male partner were associated with HIV prevalence. The high STI and UAI prevalence may lead to a burgeoning HIV epidemic among MSM, reinforcing the need for focused preventive measures incorporating complex circumstances. PMID:20467890

    This study examines different types and sources of social support in relation to psychological distress levels among older Australian gay men. A national community-based survey was conducted involving 242 gay-identified men aged 50 years and older. In univariable regressions, psychological distress was less likely if men were receiving emotional support, practical support, or had a sense of belonging, and also if they had a greater number of close friends and received some or a lot of support from family and gay friends but not from straight friends. Of all these factors, a multivariable regression showed that receiving emotional support was the only significant independent factor. Emotional support appears to play a greater role in the mental health of older gay men than many other types and sources of support. Ensuring access to emotional support may need to be considered when promoting healthier aging among gay men. PMID:26092208

    Purpose: To describe the angiographic features of hepatic involvement in hereditary hemorrhagictelangiectasia (HHT), particularly the presence of portovenous shunts. Methods: We reviewed the angiographic findings of seven patients with HHT. The patients comprised three women and four men with a mean age of 51 years. Results: Intrahepatictelangiectasias were found in all seven patients and shunts between three vascular channels were found in six of seven patients. In the four patients who had portovenous shunts combined with arterioportal shunts, the portovenous shunts were large. Three patients had noportovenous shunts. Two of these patients had arteriovenous shunts, and one had no shunt. The mean age (69 years) of the patients with portovenous shunts was older than those without portovenous shunts (26 years). Conclusions: Hepatic vascular lesions in HHT are varied, ranging from telangiectasias to large shunts between three vascular channels. In an advanced stage of involvement, large portovenous shunts are present.

    Background Despite preventive efforts, HIV incidence remains high among men who have sex with men (MSM) in industrialized countries. Condoms are an important element in prevention but, given the high frequency of condom use and their imperfect effectiveness, a substantial number and proportion of HIV transmissions may occur despite condoms. We developed a model to examine this hypothesis. Methods We used estimates of annual prevalent and incident HIV infections for MSM in Ontario. For HIV-negative men, we applied frequencies of sexual episodes and per-contact HIV transmission risks of receptive and insertive anal sex with and without a condom and oral sex without a condom. We factored in the proportion of HIV-infected partners receiving antiretroviral therapy and its impact in reducing transmissibility. We used Monte-Carlo simulation to determine the plausible range for the proportion of HIV transmissions for each sexual practice. Results Among Ontario MSM in 2009, an estimated 92,963 HIV-negative men had 1,184,343 episodes of anal sex with a condom and 117,133 anal sex acts without a condom with an HIV-positive partner. Of the 693 new HIV infections, 51% were through anal sex with a condom, 33% anal sex without a condom and 16% oral sex. For anal sex with a condom, the 95% confidence limits were 17% and 77%. Conclusions The proportion of HIV infections related to condom failure appears substantial and higher than previously thought. That 51% of transmissions occur despite condom use may be conservative (i.e. low) since we used a relatively high estimate (87.1%) for condom effectiveness. If condom effectiveness were closer to 70%, a value estimated from a recent CDC study, the number and proportion of HIV transmissions occurring despite condom use would be much higher. Therefore, while condom use should continue to be promoted and enhanced, this alone is unlikely to stem the tide of HIV infection among MSM. PMID:25211493

    Fulminant hepatitis is a rare complication of adenoviral infection that has not previously been reported in children receiving standard chemotherapy for acute leukemia. The authors have observed fatal adenovirus hepatitis in three children receiving first-line chemotherapy for acute lymphoblastic leukemia (ALL). The patients presented 10, 17, and 8 months into therapy according to the UKALL XI (third intensification), UKALL 97/99 (maintenance), and pilot UKALL 2003 (delayed intensification II) protocols, respectively. All patients received aggressive supportive care and intravenous immunoglobulins. The second and third patients were also treated with intravenous cidofovir. Despite these measures, all three children deteriorated rapidly and died of fulminant liver failure. Although rare, adenovirus infection should be considered in the differential diagnosis of acute hepatitis in children receiving standard chemotherapy for ALL. PMID:15701979

    Bragg-cell receivers are employed in specialized Electronic Warfare (EW) applications for the measurement of frequency. Bragg-cell receiver characteristics are fully characterized for simple RF emitter signals. This receiver is early in its development cycle when compared to the IFM receiver. Functional mathematical models are derived and presented in this report for the Bragg-cell receiver. Theoretical analysis is presented and digital computer signal processing results are presented for the Bragg-cell receiver. Probability density function analysis are performed for output frequency. Probability density function distributions are observed to depart from assumed distributions for wideband and complex RF signals. This analysis is significant for high resolution and fine grain EW Bragg-cell receiver systems.

    An S-band radio frequency interference (RFI) receiver to analyze and identify sources of RFI problems in the Deep Space Network DSN tracking stations is described. The RFI receiver is a constant gain, double conversion, open loop receiver with dual sine/cosine channel outputs, providing a total of 20 MHZ monitoring capability. This receiver is computer controlled using a MODCOMP II miniprocessor. The RFI receiver has been designed to operate at a 150 Kelvin system noise temperature accomplished by cascading two low noise field effect transistor (FET) amplifiers for the receiver front-end. The first stage low noise FET amplifier is mounted at the feed horn to minimize any cable losses to achieve a lower system noise temperature. The receiver is tunable over the frequency range of 2150 to 2450 MHz in both sine/cosine output channels with a resolution of 100 kHz.

    In addition to the considerations about the different types of noise sources, dynamic range, and linearity of a lidar receiver, one requires information about the pulse shape retaining capabilities of the receiver. For this purpose, relatively precise information about the height resolution as well as the recovery time of the receiver, due both to large transients and to fast changes in the received signal, is required. As more and more analog receivers using fast analog to digital converters and transient recorders will be used in the future lidar systems, methods to test these devices are essential. The method proposed for this purpose is shown. Tests were carried out using LCW-10, LT-20, and FTVR-2 as optical parts of the optical pulse generator circuits. A commercial optical receiver, LNOR, and a transient recorder, VK 220-4, were parts of the receiver system.

  20. Gut microbiota and hepatic encephalopathy.

    2013-06-01

    There is a strong relationship between liver and gut; while the portal venous system receives blood from the gut, and its contents may affect liver functions, liver in turn, affects intestinal functions through bile secretion. There is robust evidence that the pathogenesis of hepatic encephalopathy (HE) is linked to alterations in gut microbiota and their by-products such as ammonia, indoles, oxindoles, endotoxins, etc. In the setting of intestinal barrier and immune dysfunction, these by-products are involved in the pathogenesis of complications of liver cirrhosis including HE and systemic inflammation plays an important role. Prebiotics, probiotics and synbiotics may exhibit efficacy in the treatment of HE by modulating the gut flora. They improve derangement in flora by decreasing the counts of pathogenic bacteria and thus improving the endotoxemia, HE and the liver disease. Current evidence suggest that the trials evaluating the role of probiotics in the treatment of HE are of not high quality and all trials had high risk of bias and high risk of random errors. Therefore, the use of probiotics for patients with HE cannot be currently recommended. Further RCTs are required. This review summarizes the main literature findings about the relationships between gut flora and HE, both in terms of the pathogenesis and the treatment of HE. PMID:23463489

    To estimate the prevalence and predictors of hepatitis C virus (HCV) infection among inmates, a cross-sectional survey was conducted in 1994 among inmates entering six reception centers of the California Department of Corrections. Discarded serum samples were tested for antibodies to human immunodeficiency virus (HIV), HCV, hepatitis B core, and hepatitis B surface antigen (HBsAg). Of 4,513 inmates in this study, 87.0% were men and 13.0% were women. Among male inmates, 39.4% were anti-HCV-positive; by race/ethnicity, prevalences were highest among whites (49.1%). Among female inmates, 53.5% were anti-HCV-positive; the prevalence was highest among Latinas (69.7%). In addition, rates for HIV were 2.5% for men and 3.1% for women; and for HBsAg, 2.2% (men) and 1.2% (women). These data indicate that HCV infection is common among both men and women entering prison. The high seroprevalence of anti-HCV-positive inmates may reflect an increased prevalence of high-risk behaviors and should be of concern to the communities to which these inmates will be released.

    This article describes the development process of Hombres Sanos, a social marketing campaign to promote HIV testing and condom use for heterosexually identified Latino men who have sex with men and women. The steps included qualitative formative research and a social marketing analytic framework to understand our target audience better, identify incentives and barriers to risk reduction, guide product development, define an optimal promotional campaign, and inform the selection of campaign platforms. A better grasp of the authors' target beneficiaries' needs and values led to an innovative dual strategy for audience segmentation and targeting. The campaign had consumer-centered, culturally sensitive, and theory-driven communication materials. The authors found communication materials and events to be appealing and effective. The campaign was well received among the wider community, and evaluation showed promising results among Latino men in general and among heterosexually identified Latino men who have sex with men and women in particular. The authors provide a step-by-step overview of the project's formative research, including research methods and findings, and how these were translated into a social marketing campaign. In addition, the authors discuss the challenges encountered in this process and the potential of social marketing to reduce HIV risk among Latinos. PMID:22500921

    The article shows the results of treatment of 118 patients with chronic hepatitis C (CHC) which is associated with type 2 diabetes mellitus (DM). When planning therapeutic interventions in chronic hepatitis C in patients with diabetes, it is considered the presence of visceral obesit , dyslipidemia, and hepatic steatosis. The efficacy of different treatment regimens was studied. Found that the usage of ursodeoxycholic acid and ademetionin in HCV patients with diabetes type 2 receiving standard antiviral therapy (SAVT), significantly make a positive effect on the level of dyslipidemia. The normalization of lipid profile allows for a full course of SAVT, which reduces the frequency of relapse. It is also noted that the simultaneous use of ademetionin and ursodeoxycholic acid in treatment of chronic hepatitis C leads to a reduction of side effects of SAVT. Metabolic therapy may be recommended for patients with chronic hepatitis C in combination with type 2 diabetes in case of SAVT, and at its contraindications or intolerance. PMID:24523328

    SUMMARY Hepatitis E virus (HEV) infection is a worldwide disease. An improved understanding of the natural history of HEV infection has been achieved within the last decade. Several reservoirs and transmission modes have been identified. Hepatitis E is an underdiagnosed disease, in part due to the use of serological assays with low sensitivity. However, diagnostic tools, including nucleic acid-based tests, have been improved. The epidemiology and clinical features of hepatitis E differ between developing and developed countries. HEV infection is usually an acute self-limiting disease, but in developed countries it causes chronic infection with rapidly progressive cirrhosis in organ transplant recipients, patients with hematological malignancy requiring chemotherapy, and individuals with HIV. HEV also causes extrahepatic manifestations, including a number of neurological syndromes and renal injury. Acute infection usually requires no treatment, but chronic infection should be treated by reducing immunosuppression in transplant patients and/or the use of antiviral therapy. In this comprehensive review, we summarize the current knowledge about the virus itself, as well as the epidemiology, diagnostics, natural history, and management of HEV infection in developing and developed countries.

    The aim of the current project was to develop an Internet-based recruitment system for HIV and sexually transmitted infection (STI) screening for men who have sex with men (MSM) in Estonia in order to collect biological samples during behavioural studies. In 2013, an Internet-based HIV risk-behaviour survey was conducted among MSM living in Estonia. After completing the questionnaire, all participants were offered anonymous and free-of-charge STI testing. They could either order a urine sample kit by post to screen for chlamydia infections (including lymphogranuloma venereum (LGV)), trichomoniasis, gonorrhoea and Mycoplasma genitalium infections, or visit a laboratory for HIV, hepatitis A virus, hepatitis B virus,hepatitis C virus and syphilis screening. Of 301 participants who completed the questionnaire, 265 (88%),reported that they were MSM. Of these 265 MSM,68 (26%) underwent various types of testing. In the multiple regression analysis, Russian as the first language,previous HIV testing and living in a city or town increased the odds of testing during the study. Linking Internet-based behavioural data collection with biological sample collection is a promising approach. As there are no specific STI services for MSM in Estonia,this system could also be used as an additional option for anonymous and free-of-charge STI screening. PMID:25953131

    To prepare a soluble gelatin sponge (GS) and to explore the GS particles (GSPs) that inhibit development of collateral pathways when transcatheter hepatic arterial embolization is performed. The approval of the Institutional Committee on Research Animal Care of our institution was obtained. By means of 50 and 100 kDa of regenerative medicine-gelatin (RM-G), RM-G sponges were prepared by freeze-drying and heating to temperatures of 110-150{sup o}C for cross-linkage. The soluble times of RM-GSPs were measured in vitro. Eight swine for transcatheter hepatic arterial embolization were assigned into two groups: six received 135{sup o}C/50RM-GSPs, 125{sup o}C/100RM-GSPs, and 138{sup o}C/50RM-GSPs, with soluble time of 48 h or more in vitro; two swine received Gelpart GSPs (G-GSPs) with insoluble time of 14 days as a control. Transarterial chemoembolization was performed on two branches of the hepatic artery per swine. RM-GSPs heated at temperatures of 110-138{sup o}C were soluble. Mean soluble times of the RM-GSPs increased with higher temperature. Hepatic branches embolized with G-GSP remained occluded after 6 days, and development of collateral pathways was observed after 3 days. Hepatic branches embolized with 135{sup o}C/50RM-GSP and 125{sup o}C/100RM-GSP remained occluded for 4 h, and recanalization was observed after 1 day. Hepatic branches embolized with 138{sup o}C/50RM-GS remained occluded for 1 day, and recanalization was observed after 2 days with no development of collateral pathways. In RM-GSs with various soluble times that were prepared by modulating the heating temperature, 138{sup o}C/50RM-GSP was the soluble GSP with the longest occlusion time without inducing development of collateral pathways.

Despite evidence that each parameter plays a role in mate choice, we have little understanding of the relative role of each, and relationships between indices of physical appearance and general health. In this study we tested relationships between immune function and body height of young men and women. In men, we report a non-linear relationship between antibody response to a hepatitis-B vaccine and body height, with a positive relationship up to a height of 185 cm, but an inverse relationship in taller men. We did not find any significant relationship between body height and immune function in women. Our results demonstrate the potential of vaccination research to reveal costly traits that govern evolution of mate choice in humans and the importance of trade-offs among these traits.

    It is important to educate both men and women about preconception health (PCH), but limited research exists in this area. This paper examines men's and women's awareness of exposure to PCH information and of specific PCH behaviors, PCH planning, and PCH discussions with their partners. Data from Porter Novelli's 2007 Healthstyles survey were used. Women and men of reproductive age were included in the analysis (n = 2,736) to understand their awareness, planning, and conversations around PCH. Only 27.9% of women and men reported consistently using an effective birth control method. The majority of men (52%) and women (43%) were unaware of any exposure to PCH messages; few received information from their health care provider. Women were more aware than men of specific pre-pregnancy health behaviors. Women in the sample reported having more PCH conversations with their partners than did men. PCH education should focus on both women and men. Communication about PCH is lacking, both between couples and among men and women and their health care providers. PCH education might benefit from brand development so that consumers know what to ask for and providers know what to deliver. PMID:20734124

  17. Radioembolization of hepatic tumors

    Unresectable primary and metastatic liver tumors are a leading cause of cancer mortality and morbidity. This remains a challenging and key task for every oncologist despite significant advances that have been made with selective targeted systemic agents and in technology advances with radiotherapy delivery. Radioembolization (RE) is a technique of permanently implanting microspheres containing Yttrium-90 (90Y), a beta-emitting isotope with a treatment range of 2 mm, into hepatic tumors. This form of brachytherapy utilizes the unique dual vascular anatomy of the liver to preferentially deliver radioactive particles via the hepatic artery to tumor, sparing normal liver parenchyma. The main treatment inclusion criteria are patients with solid tumors, compensated liver functions, life expectancy of at least three months, and ECOG performance status 0-2. Benefit of RE has been proven in patients that have low-to-moderate extrahepatic disease burden, prior liver radiotherapy, heavy prior chemotherapy and biologic agent exposure, and history of hepatic surgery or ablation. Most of the clinical evidence is reported in metastatic colorectal, and neuroendocrine tumors (NET), and primary hepatocellular cancer. A growing body of data supports the use of RE in hepatic metastatic breast cancer, intrahepatic cholangiocarinoma, and many other metastatic tumor types. Side effects are typically mild constitutional and GI issues limited to the first 7-14 days post treatment, with only 6% grade 3 toxicity reported in large series. Potentially serious or fatal radiation induced liver disease is extremely rare, reported in only 1% or fewer in major series of both metastatic and primary tumors treated with RE. Currently, high priority prospective clinical trials are testing RE combined with chemotherapy in first line therapy for colorectal hepatic metastases, and combined with sorafenib for hepatocellular carcinomas (HCCs). Fortunately, this beneficial and now widely available therapy is

    Increased hepatic vascular resistance is the primary factor in the development of portal hypertension. Metformin ameliorates vascular cells function in several vascular beds. Our study was aimed at evaluating the effects, and the underlying mechanisms, of metformin on hepatic and systemic hemodynamics in cirrhotic rats and its possible interaction with the effects of propranolol (Prop), the current standard treatment for portal hypertension. CCl4-cirrhotic rats received by gavage metformin 300 mg/kg or its vehicle once a day for 1 wk, before mean arterial pressure (MAP), portal pressure (PP), portal blood flow (PBF), hepatic vascular resistance, and putative molecular/cellular mechanisms were measured. In a subgroup of cirrhotic rats, the hemodynamic response to acute Prop (5 mg/kg iv) was assessed. Effects of metformin ± Prop on PP and MAP were validated in common bile duct ligated-cirrhotic rats. Metformin-treated CCl4-cirrhotic rats had lower PP and hepatic vascular resistance than vehicle-treated rats, without significant changes in MAP or PBF. Metformin caused a significant reduction in liver fibrosis (Sirius red), hepatic stellate cell activation (α-smooth muscle actin, platelet-derived growth factor receptor β polypeptide, transforming growth factor-βR1, and Rho kinase), hepatic inflammation (CD68 and CD163), superoxide (dihydroethidium staining), and nitric oxide scavenging (protein nitrotyrosination). Prop, by decreasing PBF, further reduced PP. Similar findings were observed in common bile duct ligated-cirrhotic rats. Metformin administration reduces PP by decreasing the structural and functional components of the elevated hepatic resistance of cirrhosis. This effect is additive to that of Prop. The potential impact of this pharmacological combination, otherwise commonly used in patients with cirrhosis and diabetes, needs clinical evaluation. PMID:26138461

    The barbershop has been used to target African American (AA) men across age groups for health screenings, health interventions, and for research. However, few studies explore the sociodemographic characteristics of barbers and their clients. Additionally, few have evaluated the client's relative comfort with receiving health information and screenings in barbershops and other non-clinical settings. Lastly, it is unknown whether barbers feel capable of influencing health-decision making of AA men. AA male clients and barbers completed a self-administered survey in barbershops in predominantly AA neighborhoods throughout Chicago, Illinois. We assessed sociodemographic characteristics and attitudes towards receiving physical and mental health education and screenings in barbershops and other settings. Barbers were also surveyed regarding their most and least common clients by age group and their perceived ability to influence the decision-making of AA males by age group. AAs surveyed in barbershops have similar rates of high school completion, poverty and unemployment as the AA residents of their neighborhood. AA males prefer to receive health education and screening in clinician offices followed by barbershops and churches. Barbers reported serving males age 18-39 years of age most frequently while men 50 years and older were the least served group. Overall, barbers did not believe they could influence the decision-making of AA men and in the best case scenario, only 33 % felt they could influence young men 18-29 years old. Barbershops reach AA men that are representative of the demographics of the neighborhood where the barbershop is located. Barbers reach a small population of men over age 49 and feel incapable of influencing the decisions of AAs over age 39. Further studies are needed to assess other locales for accessing older AA men and to evaluate the feasibility of mental health interventions and screenings within the barbershop. PMID:26831485
