    The authors examined hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination rates, hepatitis infection, and health care access in a gym-attending sample of 311 gay, bisexual, and other men who have sex with men (MSM) in New York City. Overall, 69% reported having been vaccinated for HAV and 70% reported having been vaccinated for HBV. Multivariate models were used to identify predictors of HAV and HBV vaccination, and younger men, HIV-positive men, and men who had access to a doctor or clinic were more likely to be vaccinated than older men, HIV-negative men, and men without access to a doctor or clinic. Men with health insurance coverage were more likely to have received HBV vaccination than men without coverage. Findings indicate that there is still a significant proportion of unvaccinated men in our sample.

    Hepatitis C virus (HCV) infection is frequent in patients with end-stage renal disease treated by chronic dialysis, with a prevalence varying from 10-65% according to the geographical data. The prevalence is significantly associated with the duration of dialysis and the number of transfused blood products[1,2] and has dramatically declined with efficient blood screening.[3] We studied patients with acute HCV infection in a dialysis unit. The diagnosis was based on both anti-HCV detection and HCV-RNA detection. Other virological tools including HCV genotype determination was also used to tailor treatment to the individual patient and determine its efficacy for a one-year follow-up period. Seventeen patients (7 male and 10 female, mean age: 63.7 +/- 11.6 SD) with acute hepatitis C were enrolled to our study. All of them were followed up for a period of one year after the diagnosis was established. Phylogenetic analysis distinguished two separate HCV subtypes 1b, which were both responsible for this acute infection (see Figure 1). These types did not differ in their behavior on the clinical situation of our patients, as confirmed by the fact that in both groups of patients, there was only one patient who presented with acute illness. Six patients of our study group, three months after the acute infection, received pegylated interferon (Peg-IFNa2a) 135 mug for a six-month period. Four of them responded very well to therapy and at the first determination HCV RNA was below the cutoff point. One of our patients with very high HCV levels (HCV RNA > 50,000,000 IU/mL), despite receiving the same therapy, did not respond well and developed cirrhosis. In conclusion, it is clear from our experience that better information is needed about the current incidence, prevalence, and risk factors for HCV infection in dialysis patients. Algorithms for the diagnosis and management of hepatitis C should be developed by academic societies. Routine screening for hepatitis C also would allow

    Prevention researchers have advocated primary prevention such as vaccination in alternative venues. However, there have been major questions about both the attendance of, and the ability to, vaccinate high-risk individuals in such settings. The current study seeks to assess the feasibility of vaccinating high-risk men who have sex with men (MSM) at Gay Pride events. The research questions are: Do gay men who are sampled at Gay Pride events engage in more or less risky behavior than gay men sampled at other venues? Do the gay men who receive hepatitis vaccinations at Gay Pride engage in more or less risky behavior than gay men at Gay Pride who do not receive hepatitis vaccination? Of the 3689 MSM that completed the Field Risk Assessment (FRA), 1095/3689 = 29.68% were recruited at either the 2006 or 2007 Long Beach, California Gay Pride events. The remaining, 2594/3689 = 70.32% were recruited at Long Beach gay bars, gay community organizations and institutions, and through street recruitment in various gay enclaves in the Long Beach area. Logistic regression analysis yielded eight factors that were associated with non-attendance of Gay Pride: Age, had sex while high in the last 12 months, had unprotected anal intercourse (UAI) in the last 12 months, had sex for drugs/money in the last 12 months, been diagnosed with a sexually transmitted infection (STI) in the last 12 months, used nitrites (poppers) in the last 12 months, and used methamphetamine in the last 12 months. Identifying as White, Asian, or African American compared to Hispanic was also associated with non-attendance. Bivariate analysis indicated that, of the MSM sampled at Gay Pride, 280/1095 = 25.57% received a hepatitis vaccination there. The MSM sampled at Gay Pride who reported engaging in UAI or having used any stimulant (cocaine, crack-cocaine, or methamphetamine) in the last 12 months were more likely to receive hepatitis vaccination on-site. The results provide evidence for the viability of

    Though a potent vaccine represents a powerful preventive tool, the policy of its use is governed by epidemiological and economical factors. Hepatitis A, an enterically transmitted disease shows distinct association with socio-economic status, populations with improvement experiencing lower exposure to the virus. With the availability of vaccine, it is pertinent to consider its use in the effective control of the disease. However, with the varied epidemiological patterns and economical constraints in different countries it does not seem to be possible to evolve universal policy for immunization. Though, universal immunization may be the most effective way of control, the same is not practical for many countries. It is proposed that irrespective of endemicity of hepatitis A, high-risk groups such as travelers to endemic areas, patients suffering from chronic liver diseases, HBV and HCV carriers, tribal communities with high HBV carrier rates, food handlers, sewage workers, recipients of blood products, troops, and children from day-care centers should be immunized with hepatitis A vaccine. In addition, for populations with intermediate prevalence, infants, children from affordable families may be immunized. As coupling the vaccine with EPI schedule would be beneficial, use of combined A & B or A, B & E vaccine may be an attractive alternative.

    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

    Hepatitis A virus (HAV) and hepatitis B virus (HBV) continue to be major health concerns among men who have sex with men (MSM). The Internet both facilitates high-risk sexual encounters and provides opportunities for promoting healthy behaviours. This study compared self-reported HAV and HBV vaccination levels, based on demographics, health characteristics, hepatitis knowledge, attitudes and risk behaviours among MSM using an online survey posted from February through June 2005. Each participant (n = 968) reported whether they were vaccinated, infected or susceptible for hepatitis A and/or for hepatitis B. Men whose health-care provider recommended vaccination were 12.91 (95% confidence interval [CI] 8.11, 20.55) times more likely to be vaccinated against HAV and 17.93 (95% CI 10.82, 29.70) times more likely to be vaccinated against HBV than those at risk of infection, respectively. These data provide essential information for public health professionals to successfully promote vaccination among members of this population.

    Background Testosterone therapy for older men has increased substantially over the past decade. Research on the effects of testosterone therapy on cardiovascular outcomes has yielded inconsistent results. Objective To examine the risk of myocardial infarction (MI) in a population-based cohort of older men receiving intramuscular testosterone. Method Using a 5% national sample of Medicare beneficiaries, we identified 6355 patients treated with at least 1 injection of testosterone between January 1, 1997, and December 31, 2005. We matched this cohort to 19 065 testosterone nonusers at a 1:3 ratio based on a composite MI prognostic score. Patients were followed until December 31, 2005, or until they lost coverage from Medicare, enrolled in a health maintenance organization, experienced a MI, or died. Result In a Cox regression analysis adjusting for demographic and clinical characteristics, receipt of testosterone therapy was not associated with an increased risk of MI (hazard ratio [HR] = 0.84; 95% CI = 0.69–1.02). In this analysis, there was an interaction between receipt of testosterone and quartile of risk of MI (P = 0.023). For men in the highest quartile of the MI prognostic score, testosterone therapy was associated with a reduced risk of MI (HR = 0.69; 95% CI = 0.53–0.92), whereas there was no difference in risk for the first (HR = 1.20; 95% CI = 0.88–1.67), second (HR = 0.94; 95% CI = 0.69–1.30), and third quartiles (HR = 0.78; 95% CI = 0.59–1.01). Conclusion Older men who were treated with intramuscular testosterone did not appear to have an increased risk of MI. For men with high MI risk, testosterone use was modestly protective against MI.

    Although vaccination against hepatitis A virus (HAV) is essential for human immunodeficiency virus (HIV)-infected patients, the uptake of HAV vaccine is reported to be very low. From 2007 to 2012, 912 HIV-infected men in Athens, Greece were screened for exposure to HAV. Two doses of an HAV vaccine were recommended to 569 eligible patients. Reminder cards with scheduled vaccination visits were given to each patient. Among eligible patients, 62.2% (354/569) received both doses. Patients who were fully vaccinated compared with non-adherent patients were natives, older, had undetectable HIV viral load, higher CD4 T cell counts and lower nadir CD4 T cell counts. Multivariate logistic regression revealed that the patient's country of origin (p = 0.024; OR = 2.712; 95% CI, 1.139-6.457), CD4 T cell count (p < 0.001) and nadir CD4 T cell count (p < 0.001) were factors directly associated with adherence. In conclusion, adherence to HAV vaccination was better than in previously published data. Because many of the factors related to vaccination completion are parameters of HIV infection, it appears that physician interest in HIV care and vaccination planning is crucial to enhancing vaccine uptake.

    In a consecutive medicolegal necropsy series benign hepatic tumours and tumour like conditions occurred in 52% of the 95 men aged 35-69 years. The incidence increased with age, mainly due to small bile duct tumours (n = 26; mean age 56.7 years; p less than 0.01; mean size 1.3 mm). The next most common tumours were cavernous hemangiomas (n = 19; mean age 53.9 years; mean size 5.2 mm) that were not related to age. Focal nodular hyperplasia (n = 3; mean size 8.0 mm) tended to occur in a younger age group (mean age 40.3 years; p less than 0.001). Multiple bile duct tumours were present in 46% and hemangiomas in 50% of the men studied. Liver cell adenoma, nodular regenerative hyperplasia, and peliosis hepatis were incidental findings (one case of each). Nodular regenerative hyperplasia was associated with the consumption of alcohol and a total dose of 21.5 g of testosterone. These results indicate that benign hepatic tumours and tumour like conditions are not rare in men but may remain undetected because of their small size. Images PMID:3950039

    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.

    Despite the availability of safe and effective vaccines, little is known about prevalence and risk factors for hepatitis A (HAV) and hepatitis B virus (HBV) infection among Thai men who have sex with men. The prevalence of HAV and HBV infection among men who have sex with men cohort in Bangkok was assessed. Baseline blood specimens were drawn and demographic and behavioral data were collected. Bivariate and multivariate logistic regression analysis was used to analyze risk factors for prevalent HAV and HBV infection. One thousand two hundred ninety-nine Thai men who have sex with men 18 years and older were enrolled. Among those with results, 349/1,291 (27.0%) had evidence of past or current hepatitis A infection. Of the 1,117 (86.5%) men with unambiguous HBV test results, 442 (39.6%) had serologic evidence of past/current infection, 103 (9.2%) were immune due to hepatitis B vaccination, 572 (51.2%) had no evidence of immunological exposure to HBV or vaccine. Of those with past/current HBV infection, 130 (29.4%) were HIV positive. Age >35 years was independently associated with both HAV and HBV infection. University education was protective against both HAV and HBV infection. Increased alcohol consumption, number of lifetime male sexual partners ≥10, and prevalent HIV infection were also independently associated with HBV infection. The prevalence of past/current HAV and HBV infection was high in Bangkok men who have sex with men. Age-cohorts with a higher prevalence of hepatitis B vaccine induced immunity may be expected in the future. Hepatitis A and B vaccination is recommended.

    To assess the epidemiology of hepatitis B virus (HBV) infection among men who have sex with men (MSM) in Peru, we evaluated the prevalence and associated risk factors for HBV serologic markers among participants of a HIV sentinel surveillance conducted in 2002-2003. The standardized prevalences for total antibodies to hepatitis B core antigen (anti-HBc) and hepatitis B surface antigen (HBsAg) were 20.2% and 2.8%, respectively. Individuals with human immunodeficiency virus (HIV-1) infection had significantly higher anti-HBc (44.3% versus 19.3%) and HBsAg (9.5% versus 2.3%) prevalences than uninfected men. Increasing age (adjusted odds ratio [AOR] = 1.06), versatile sexual role (AOR = 1.59), sex in exchange for money/gifts (AOR = 1.58), syphilis (AOR = 1.74), HIV-1 infection (AOR = 1.64), and herpes simplex virus type 2 (HSV-2, AOR = 2.77) infection were independently associated with anti-HBc positivity, whereas only HIV-1 infection (AOR = 3.51) and generalized lymph node enlargement (AOR = 3.72) were associated with HBsAg positivity. Pre-existing HBV infection is very common among Peruvian MSM and was correlated with sexual risk factors. MSM in Peru constitute a target population for further HBV preventive and treatment interventions.

    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

    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.

    Prisoner populations are characterized by high rates of hepatitis C (HCV), up to thirty times that of the general population in Australia. Within Australian prisons, less than 1% of eligible inmates access treatment. Public health strategies informed by social capital could be important in addressing this inequality in access to HCV treatment. Twenty-eight male inmates participated in qualitative interviews across three correctional centres in New South Wales, Australia. All participants had recently tested as HCV RNA positive or were receiving HCV treatment. Analysis was conducted with participants including men with experiences of HCV treatment (n=10) (including those currently accessing treatment and those with a history of treatment) and those who were treatment naïve (n=18). Social capital was a resourceful commodity for inmates considering and undergoing treatment while in custody. Inmates were a valuable resource for information regarding HCV treatment, including personal accounts and reassurance (bonding social capital), while nurses a resource for the provision of information and care (linking social capital). Although linking social capital between inmates and nurses appeared influential in HCV treatment access, there remained opportunities for increasing linking social capital within the prison setting (such as nurse-led engagement within the prisons). Bonding and linking social capital can be valuable resources in promoting HCV treatment awareness, uptake and adherence. Peer-based programmes are likely to be influential in promoting HCV outcomes in the prison setting. Engagement in prisons, outside of the clinics, would enhance opportunities for linking social capital to influence HCV treatment outcomes.

    Three open-label, single-dose studies investigated the impact of hepatic or renal impairment on abiraterone acetate pharmacokinetics and safety/tolerability in non-cancer patients. Patients (n = 8 each group) with mild/moderate hepatic impairment or end-stage renal disease (ESRD), and age-, BMI-matched healthy controls received a single oral 1,000 mg abiraterone acetate (tablet dose); while patients (n = 8 each) with severe hepatic impairment and matched healthy controls received 125- and 2,000-mg abiraterone acetate (suspension doses), respectively (systemic exposure of abiraterone acetate suspension is approximately half to that of tablet formulation). Blood was sampled at specified timepoints up to 72 or 96 hours postdose to measure plasma abiraterone concentrations. Abiraterone exposure was comparable between healthy controls and patients with mild hepatic impairment or ESRD, but increased by 4-fold in patients with moderate hepatic impairment. Despite a 16-fold reduction in dose, abiraterone exposure in patients with severe hepatic impairment was about 22% and 44% of the Cmax and AUC∞ of healthy controls, respectively. These results suggest that abiraterone pharmacokinetics were not changed markedly in patients with ESRD or mild hepatic impairment. However, the capacity to eliminate abiraterone was substantially compromised in patients with moderate or severe hepatic impairment. A single-dose administration of abiraterone acetate was well-tolerated.

    Hepatitis C virus (HCV) infection occurs among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) because of shared routes of transmission. To assess the association between HCV and HIV infection among MSM in Peru, we conducted a matched case-control study (162 HIV-positive cases and 324 HIV-negative controls) among participants of an HIV sentinel surveillance survey in six urban cities. The HCV infection was initially screened using anti-HCV ELISA and immunoblot assay, and thereafter confirmed by the HCV RNA qualitative assay. Among cases, no confirmed HCV infection was found while among controls, only two confirmed HCV infections were reported (0.62%). This matched case-control reports a very low probability of association between HCV and HIV co-infection and suggests a very low prevalence of HCV infection among MSM in Peru.

    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

    Purpose Androgen deprivation therapy is associated with fracture risk in men with prostate cancer. We assessed the effects of toremifene, a selective estrogen receptor modulator, on fracture incidence in men receiving androgen deprivation therapy during a 2-year period. Materials and Methods In this double-blind, placebo controlled phase III study 646 men receiving androgen deprivation therapy for prostate cancer were assigned to toremifene (80 mg by mouth daily) and 638 were assigned to placebo. Subjects were followed for 2 years. The primary study end point was new vertebral fractures. Secondary end points included fragility fractures, bone mineral density and lipid changes. Results The 2-year incidence of new vertebral fractures was 4.9% in the placebo group vs 2.5% in the toremifene group, a significant relative risk reduction of 50% (95% CI –1.5 to 75.0, p = 0.05). Toremifene significantly increased bone mineral density at the lumbar spine, hip and femoral neck vs placebo (p <0.0001 for all comparisons). There was a concomitant decrease in markers of bone turnover (p <0.05 for all comparisons). Toremifene also significantly improved lipid profiles. Venous thromboembolic events occurred more frequently with toremifene than placebo with 7 subjects (1.1%) in the placebo group experiencing a venous thromboembolic event vs 17 (2.6%) in the toremifene group. Other adverse events were similar between the groups. Conclusions Toremifene significantly decreased the incidence of new vertebral fractures in men receiving androgen deprivation therapy for prostate cancer. It also significantly improved bone mineral density, bone turnover markers and serum lipid profiles. PMID:20723926

    Background. Sexual transmission of hepatitis C virus (HCV) among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) is an emerging issue. Studies addressing the temporal trends and risk factors associated with incident HCV in HIV-infected MSM in the community-based primary care settings in the United States are scarce. Methods. Using a retrospective cohort study design, HCV incidence, defined as HCV antibody seroconversion, was determined in 1147 HIV-infected men receiving care at Chase Brexton Health Care clinics in Baltimore, Maryland between 2004 and 2014. Multivariate regression analyses were used to identify factors associated with incident HCV. Results. There were 42 incident HCV infections during 5242 person-years (PY) of follow up (incidence rate [IR], 8.01/1000 PY). Thirty-seven (88%) of the incident infections were in MSM, of whom 31 (84%) reported no injection-drug use (IDU). The annual IRs for MSM were 13.1–15.8/1000 PY between 2004 and 2007, decreased to 2.7–6.2/1000 PY between 2008 and 2011, and increased to 10.4/1000 PY and 13.3/1000 PY in 2013 and 2014, respectively. Injection-drug use was strongly associated with incident HCV among all MSM (IR ratio [IRR], 14.15; P = .003); however, among MSM without IDU, entering care between 2010 and 2013 (IRR, 3.32; P = .01), being employed (IRR, 3.14; P = .03), and having a history of ulcerative sexually transmitted infections (IRR, 3.70; P = .009) or of polydrug use (IRR, 5.54; P = .01) independently predicted incident HCV. Conclusions. In this cohort of HIV-infected men, a re-emerging HCV epidemic was observed from 2011 to 2014 among MSM. In addition to IDU, high-risk sexual behaviors, favorable socioeconomic status, and polydrug use fueled this increase in HCV infections. PMID:27703998

    Since 2000, an increase in hepatitis C virus infection among HIV-infected (HIV+) men who have sex with men has been observed. Evidence points to blood exposure during sex as the medium of hepatitis C virus transmission. Hepatitis C virus prevalence among HIV + MSM overall and in relation to injection drug use is poorly characterized. In this study, a systematic review and meta-analysis examining global hepatitis C virus antibody prevalence and estimating active hepatitis C virus prevalence among HIV + MSM were conducted; 42 reports provided anti-hepatitis C virus prevalence data among HIV + MSM. Pooled prevalence produced an overall anti-hepatitis C virus prevalence among HIV + MSM of 8.1%; active HCV prevalence estimate was 5.3%-7.3%. Anti-hepatitis C virus prevalence among injection drug use and non-injection drug use HIV + MSM was 40.0% and 6.7%, respectively. Among HIV + MSM, hepatitis C virus prevalence increased significantly over time among the overall and non-injection drug use groups, and decreased significantly among injection drug use HIV + MSM. We identified a moderate prevalence of hepatitis C virus among all HIV + MSM and among non-injection drug use HIV + MSM; for both, prevalence was observed to be increasing slightly. Pooled prevalence of hepatitis C virus among HIV + MSM was higher than that observed in the 1945-1965 US birth cohort. The modest but rising hepatitis C virus prevalence among HIV + MSM suggests an opportunity to control HCV among HIV + MSM; this combined with data demonstrating a rising hepatitis C virus incidence highlights the temporal urgency to do so.

    Thirty five homosexual men (17 positive for antibody to the human immunodeficiency virus (HIV) and 18 consistently negative) were vaccinated against hepatitis B virus infection. Eight of the 17 seropositive patients failed to develop detectable hepatitis B surface antibody within three months of the third injection compared with only one of the 18 seronegative patients (p less than 0.01). HIV infection is prevalent in the developed world in groups at risk for hepatitis B infection and in certain Third World countries where widespread vaccination programmes exist. This study shows the impact that coincident HIV infection may have on an otherwise efficacious vaccine. The efficacy of this and other vaccines in patients infected with HIV needs to be studied urgently.

    Purpose Whether race influences bone loss and fracture risk during androgen deprivation therapy (ADT) for prostate cancer is unknown. Using data from a prospective, clinical trial, we compared bone mineral density (BMD) and fracture between African American and Caucasian men receiving ADT. Materials and Methods Subjects (n=516) were in the placebo group of a two-year randomized placebo controlled fracture prevention trial and were African American (n=68) or Caucasian (n=448). We compared baseline characteristics, changes in BMD, and rates of new fractures between races. Results Compared to Caucasian men, African American men had higher baseline hip BMD (0.98 ± 0.15 g/m2 versus 0.91 ± 0.15 g/m2; P=0.001) and similar spine BMD (1.09 ± 0.22 versus 1.11 ± 0.22; P=0.51). There was no difference in prevalent vertebral fractures between African American and Caucasian men (7.4% versus 15.0%; P=0.13). Percentage change in hip BMD at two years was similar between African American and Caucasian men (−2.21 ± 0.59% versus −2.54 ± 0.26%; P=0.65). Changes in BMD of the lumbar spine were also similar between African American and Caucasian men (−1.74 ± 0.69 versus −1.30 ± 0.33%; P=0.64). No new vertebral fractures were reported in African American men versus two fractures in Caucasian men. Conclusions In a clinical trial, African American men receiving ADT for prostate cancer have higher hip BMD and tended to have fewer prevalent vertebral fractures than Caucasian men. Despite lower baseline risk of osteoporosis and fracture, African American men experience a decline in BMD that is similar to Caucasian men. PMID:22245322

    Background Cambodian Americans have an elevated risk of liver cancer. This health disparity is attributable to high rates of hepatitis B virus (HBV) infection. Our study examined factors associated with HBV testing among Cambodian men and women. Methods A population-based survey was conducted in the Seattle area. The Health Behavior Framework guided our survey instrument development. We attempted to interview a man and a woman in each household. Results The sample included 300 men and 367 women. About one-half of the male (45%) and female (54%) respondents had been tested for HBV. Two factors were independently associated with testing among men and women: a doctor had recommended testing and had asked a doctor for testing. Knowing that someone who looks and feels healthy can spread HBV was independently associated with testing among men. Discussion Low levels of HBV testing remain a public health problem among Cambodians. Interventions should improve patient-provider communication by encouraging providers who serve Cambodians to recommend HBV testing, as well as by empowering Cambodians to ask for testing.

    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.

    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

    Renal functional decline that is frequently seen during chronic hepatitis B (CHB) treatment can exert adverse effects on overall prognosis. It, however, is difficult to distinguish vulnerable patients who may experience renal dysfunction because most previous CHB studies were conducted in relatively healthy individuals. In this retrospective observational study, renal functional decline in CHB patients receiving oral antiviral agents for more than 6 months was analyzed and risk factors of chronic kidney disease (CKD) progression were determined. Renal functional decline was defined when the estimated glomerular filtration rate (eGFR) decreased by more than 25% from baseline and rapid CKD progression was defined as eGFR decreased by more than 5 mL/min/1.73 m2/y among patients who experienced renal functional decline. A total of 4178 patients were followed up for a median 23 months. Antiviral agents included lamivudine (17.0%), adefovir (3.7%), entecavir (70.4%), telbivudine (0.6%), tenofovir (4.0%), or clevudine (4.3%). Renal functional decline occurred in 706 (16.9%) patients. Based on multivariate Cox regression analysis, age, hypertension, diabetes, history of liver or kidney transplantation, underlying underlying CKD, and simultaneous administration of diuretics increased the hazard ratio for renal functional decline; however, clevudine reduced risk. The eGFR significantly increased over time in patients receiving telbivudine or clevudine compared with lamivudine. Among the 3175 patients followed up for more than 1 year, 407 (12.8%) patients experienced rapid CKD progression. Patients with rapid CKD progression showed lower serum albumin, higher total bilirubin, and prolonged prothrombin time compared with patients with stable renal function, but hepatitis B envelope antigen positivity and hepatitis B virus deoxyribonucleic acid level did not differ between the control and rapid CKD progression groups. Age, diabetes, kidney transplantation, underlying CKD, and

    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.

    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.

    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

    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.

    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.

    Outbreaks of acute hepatitis C virus (HCV) infection are occurring in HIV-infected men who have sex with men. We evaluated risk factors and liver histopathology in 11 consecutively enrolled men with newly acquired HCV infection that was diagnosed on the basis of antibody seroconversion, new elevations in alanine aminotransferase level, and wide fluctuations in HCV RNA level. Ten patients reported unprotected anal intercourse, and 7 reported “club-drug” use, including methamphetamine. Liver biopsy showed moderately advanced fibrosis (Scheuer stage 2) in 9 patients (82%). No cause of liver damage other than acute HCV infection was identified. The specific pathways leading to periportal fibrosis in HIV-infected men with newly acquired HCV infection require investigation. PMID:18627270

    Background. Loss of bone density with androgen deprivation therapy for prostate cancer is well recognized. We assessed the effects of quarterly infusion of zoledronic acid on bone mineral density (BMD) and markers of bone turnover over a one-year period in men receiving gonadotropin-releasing hormone analog (GnRH-a) for prostate cancer. Methods. 41 subjects were randomly assigned to treatment with zoledronic acid (4 mg) IV infusion or placebo every 3 months. The primary endpoint was the change in the lumbar spine BMD after 12 months of treatment. Results. The change in vertebral BMD in the zoledronic acid group (+7.93 ± 1.4%) was significantly (P < .05) greater than the change in the placebo group (+0.82 ± 1.7%) as was the change in left femoral neck BMD (+5.05 ± 1.4% for the zoledronic acid group versus -0.48 ± 1.4% for the placebo group). The decrease in biochemical markers of bone turnover was significantly (P < .05) greater in the zoledronic acid group compared to the placebo group. Conclusion. Quarterly infusion of zoledronic acid for 1 year improved vertebral and left femoral neck BMD with a decrease in bone turnover markers in men on GnRH-a treatment. Zoledronic acid treatment appears to be promising in men with low BMD receiving GnRH-a treatment.

    Abstract Hepatitis B virus (HBV) reactivation in the setting of rituximab use is a potentially fatal but preventable safety event. The rate of HBV screening and proportion of patients at risk who receive antiviral prophylaxis in patients initiating rituximab is unknown. We analyzed electronic health record (EHR) data from 2 health systems, a university center and a safety net health system, including diagnosis grouper codes, problem lists, medications, laboratory results, procedures codes, clinical encounter notes, and scanned documents. We identified all patients who received rituximab between 6/1/2012 and 1/1/2016. We calculated the proportion of rituximab users with inadequate screening for HBV according to the Centers for Disease Control guidelines for detecting latent HBV infection before their first rituximab infusion during the study period. We also assessed the proportion of patients with positive hepatitis B screening tests who were prescribed antiviral prophylaxis. Finally, we characterized safety failures and adverse events. We included 926 patients from the university and 132 patients from the safety net health system. Sixty-one percent of patients from the university had adequate screening for HBV compared with 90% from the safety net. Among patients at risk for reactivation based on results of HBV testing, 66% and 92% received antiviral prophylaxis at the university and safety net, respectively. We found wide variations in hepatitis B screening practices among patients receiving rituximab, resulting in unnecessary risks to patients. Interventions should be developed to improve patient safety procedures in this high-risk patient population. PMID:28353614

    The purpose of this study was to examine patterns and predictors of HIV/STI risk over time among Latino migrant men in a new receiving community. Latino men (N = 125) were interviewed quarterly for 18 months and HIV/STI tested annually. Selected individual, environmental and cultural factors by partner type and condom use were explored longitudinally and in a cross-section. Sex with female sex workers (FSWs) and multiple partners decreased, sex with main partners and abstinence increased, while the number of casual partners remained stable. Consistent condom use was highest with FSWs, lowest with main partners and midrange with casual partners with no trends over time. STI morbidity was low; no HIV was detected. Drug use and high mobility were associated with inconsistent condom use with FSW, whereas having family in the household was protective. HIV/STI prevention efforts should focus on drug using Latino migrants who are highly mobile and should foster healthy social connections.

  10. Fulminant hepatitis and fatal toxic epidermal necrolysis (Lyell disease) coincident with clarithromycin administration in an alcoholic patient receiving disulfiram therapy.

    Disulfiram is widely used in the treatment of chronic alcoholism. Adverse drug reactions with fatal outcome following disulfiram therapy are infrequent, and hepatic failure accounts for most of them. Since disulfiram is a cytochrome P450 (CYP450) enzyme system inhibitor, numerous interactions with several drugs metabolized in the liver have been reported. Like disulfiram, clarithromycin inhibits a CYP450 isoenzyme, but, despite its widespread use for the treatment of respiratory tract infections, no interactions with disulfiram have been described as yet. We report a case of fatal toxic epidermal necrolysis (Lyell disease) and fulminant hepatitis shortly after starting treatment with clarithromycin in a patient who was receiving disulfiram. This is the first case of such a severe dermatosis in a patient receiving either disulfiram or clarithromycin therapy. The temporal relationship between drug administration and clinical symptoms in this case suggests a probable interaction between the 2 drugs.

    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.

    Cyproterone acetate is a steroidal anti-androgen that has been used in human medicine for contraceptive purposes as well as treatment of medical conditions responsive to suppression of testosterone production. While serious side effects are considered to be rare, sporadic cases of severe hepatitis have been reported, including several fatal cases. This report describes a case of fatal fulminant hepatitis in one of four male chimpanzees (Pan troglodytes) that were undergoing trial treatment with cyproterone acetate to decrease inter-male aggression.

    This study investigated HIV, hepatitis B (HBV) and C (HCV) and syphilis prevalence and associated behavioural correlates to HIV infection among gay, transsexuals and men who have sex with men (GTMSM) in the Dominican Republic using respondent-driven sampling. Eligible men were aged ≥15 years, reported engaging in anal/oral sex with another man within the past six months and living in one of the four cities sampled. GTMSM were recruited in Santo Domingo (n = 510), Barahona (n = 281), La Altagracia (n = 270) and Santiago (n = 327). HIV seroprevalence ranged from 5.1% to 7.6%. HBV ranged from 0.6% to 3.5%, HCV from 0.8% to 6.9% and syphilis from 3.5% to 6.9%. GTM practice numerous risky sexual behaviours including having multiple sex partners and practising inconsistent condom use with male and female, including transactional, sex partners. Although we found lower HIV prevalence compared with previous studies, the high level of extremely risky sexual behaviours practised by GTM in the Dominican Republic will most likely result in increases in HIV and other infections if action is not taken to scale-up effective prevention programmes for this population.

    Hepatitis A is an acute, usually self-limiting infection of the liver caused by a virus known as hepatitis A virus (HAV). Humans are the only reservoir of the virus; transmission occurs primarily through the fecal-oral route and is closely associated with poor sanitary conditions. The virus has a worldwide distribution and causes about 1.5 million cases of clinical hepatitis each year. The risk of developing symptomatic illness following HAV infection is directly correlated with age. As many 85% of children below 2 y and 50% of those between 2-5 y infected with HAV are anicteric, and among older children and adults, infection usually causes clinical disease, with jaundice occurring in more than 70% of cases. The infection is usually self-limiting with occasional fulminant hepatic failure and mortality. In most developing countries in Asia and Africa, hepatitis A is highly endemic such that a large proportion of the population acquires immunity through asymptomatic infection early in life. HAV is endemic in India; most of the population is infected asymptomatically in early childhood with life-long immunity. Several outbreaks of hepatitis A in various parts of India have been recorded in the past decade such that anti-HAV positivity varied from 26 to 85%. Almost 50% of children of ages 1-5 y were found to be susceptible to HAV. Any one of the licensed vaccines may be used since all have nearly similar efficacy and safety profiles (except for post-exposure prophylaxis / immunocompromised patients, where only inactivated vaccines may be used). Two doses 6 mo apart are recommended for all vaccines. All Hepatitis A vaccines are licensed for use in children aged 1 y or older. However in the Indian scenario, it is preferable to administer the vaccines at age 18 mo or more when maternal antibodies have completely declined. Vaccination at this age is preferable to later since it is easier to integrate with the existing schedule, protects those who have no antibodies, and

    Hepatitis C infection and its treatment have been associated with extrahepatic manifestations, including different skin conditions. Over the past decades, a greater number of drugs have been implicated as triggers for drug-induced subacute cutaneous lupus erythematosus. We report a case of a 42-year-old Hispanic man who developed a forehead violaceous rash during treatment with pegylated interferon alpha-2a as part of his therapy against hepatitis C infection that subsequently resulted to be subacute cutaneous lupus erythematosus. The skin lesion improved with discontinuation of medication and some topic therapy.

    The incidence of hepatitis C virus (HCV) infections among human immunodeficiency virus (HIV)‐infected men who have sex with men has increased in recent years and is associated with high‐risk sexual behavior. Behavioral interventions that target high‐risk behavior associated with HCV transmission and treatment with direct‐acting antivirals may prevent further HCV infections. We predicted the effect of behavioral and treatment interventions on HCV incidence and prevalence among HIV‐infected men who have sex with men up to 2030 using a HCV transmission model parameterized with data from the Swiss HIV Cohort Study. We assessed behavioral interventions associated with further increase, stabilization, and decrease in the size of the population with high‐risk behavior. Treatment interventions included increase in treatment uptake and use of direct‐acting antivirals. If we assumed that without behavioral interventions high‐risk behavior spread further according to the trends observed over the last decade and that the treatment practice did not change, HCV incidence converged to 10.7/100 person‐years. All assessed behavioral interventions alone resulted in reduced HCV transmissions. Stabilization of high‐risk behavior combined with increased treatment uptake and the use of direct‐acting antivirals reduced incidence by 77% (from 2.2 in 2015 to 0.5/100 person‐years) and prevalence by 81% (from 4.8% in 2015 to 0.9%) over the next 15 years. Increasing treatment uptake was more effective than increasing treatment efficacy to reduce HCV incidence and prevalence. A decrease in high‐risk behavior led to a rapid decline in HCV incidence, independent of treatment interventions. Conclusion: Treatment interventions to curb the HCV epidemic among HIV‐infected men who have sex with men are effective if high‐risk behavior does not increase as it has during the last decade; reducing high‐risk behavior associated with HCV transmission would be the most

    We investigated the effects of the fatty acid oxidation inhibitor etomoxir (ETO) on food intake and on fat and carbohydrate metabolism in two double-blind crossover studies in male, normal-weight subjects. In study 1, ETO (75 mg [+]-racemate) or placebo was given orally 30 min after completion of a standardized, fat-enriched (total energy: 2698 kJ, 40% from fat) lunch. The subjects (n = 15) were isolated from external time cues and free to choose when to eat dinner from an oversized serving (total energy: 6656 kJ, 60% from fat). In study 2, subjects (n = 13) were selected for habitually high fat intake (mean: 44% of energy intake). ETO (150 mg) or placebo was given after an overnight fast, 2.5 h before offering an oversized high fat breakfast (6960 kJ, 72% from fat). In both studies, blood samples were taken and the respiratory quotient (RQ) was measured several times during each test period. In study 1, ETO (75 mg) did not affect the timing and size of the dinner or subjective feelings of hunger and satiety. Although ETO (75 mg) did not affect the RQ, it decreased plasma beta-hydroxybutyrate (BHB) and increased plasma lactate compared with placebo. Plasma triacylglycerols (TG), free fatty acids (FFA), glucose, and insulin were not affected by ETO. In study 2, ETO (150 mg) enhanced hunger feelings and increased the size of the breakfast by 22.7%. ETO did not affect the RQ, but baseline RQ was lower in study 2 than in study 1 (0.83 versus 0.89, P < 0.01). Compared with placebo, ETO (150 mg) decreased plasma BHB and increased plasma FFA and plasma lactate. Baseline plasma concentrations of BHB, FFA, and lactate were higher in study 2 than in study 1 (BHB: 242 versus 81 mumol/L, P < 0.001; FFA: 0.674 versus 0.406 mmol/L, P < 0.01; lactate: 1.08 versus 0.74 mmol/L, P < 0.05). Plasma concentrations of TG, glucose, and insulin were not affected by ETO. The results suggest that inhibition of hepatic fatty acid oxidation stimulates eating in men when baseline fatty acid

    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

    We characterized the early dynamics of hepatitis B virus (HBV) quasispecies evolution during the first weeks of antiviral therapy with low-to-moderate genetic barrier antiviral drugs and associated these data with antiviral response patterns. Fifteen chronic hepatitis B patients (men, 10; mean age, 34; HBeAg positive, 6) who received lamivudine or telbivudine for at least 52 weeks were included. HBV DNA was extracted from serum, and a 910-bp fragment covering domains A-F of the reverse transcriptase region was amplified, cloned and sequenced. Parameters of quasispecies heterogeneity, genetic diversity and complexity were calculated and were correlated with complete virologic response, defined as undetectable HBV DNA at week 52. Nine patients achieved complete virologic response during the observational period. While baseline HBV DNA levels and HBeAg status were associated with virologic response, baseline quasispecies complexity and diversity of responders showed no significant difference to those of nonresponders (P > 0.05). However, at week 4, quasispecies complexity of nonresponders was significantly higher compared with that of responders on the nucleotide level (P = 0.01) and the aa level (P = 0.04). The number of synonymous substitutions per synonymous site dropped significantly in responders at week 4 (P = 0.04), while there was no difference in nonresponders. The HBV quasispecies complexity at the early stage of antiviral therapy (week 4) with the low-to-moderate genetic barrier nucleoside analogs lamivudine or telbivudine was associated with subsequent virologic response. Further studies are needed to confirm HBV quasispecies evolution as additional predictive marker for beneficial treatment outcome.

    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.

    Background Since 2000, there has been a marked rise in acute hepatitis C virus (HCV) in HIV-positive men who have sex with men (MSM). We conducted an international phylogenetic study to investigate the existence of an HCV transmission network among MSM. Methods HIV-positive MSM diagnosed with recent HCV (n=226) in England (107), Netherlands (58), France (12), Germany (25) and Australia (24) between 2000 and 2006 were enrolled into a molecular phylogenetic study. Using real-time PCR, the NS5B region of the HCV genome (436 bp) was amplified, sequenced and compared with unrelated NS5B sequences. Results NS5B sequences were obtained from 200 (89%) cases. Circulating HCV genotypes were 1a (59%); 4d (23%), 3a (11%), 1b (5%), and 2b/c (3%). Phylogenetic analysis revealed 156 (78%) sequences that formed 11 clusters (bootstrap value >70%) containing between 4 and 37 individual sequences. Country mixing was associated with larger cluster size (17 vs 4.5 sequences; p=0.03). ‘Molecular clock’ analysis indicated that the majority (85%) of transmissions occurred since 1996. Discussion Phylogenetic analysis revealed a large international network of HCV transmission among HIV-positive MSM. The rapid spread of HCV among neighboring countries is supported by the large proportion (74%) of European MSM infected with an HCV strain co-circulating in multiple European countries; the low evolutionary distances among HCV isolates from different countries; and the trend toward increased country mixing with increasing cluster size. Temporally, this epidemic coincides with the introduction of highly active anti-retroviral therapy and associated increases in sexual risk behaviors. International collaborative public health efforts are needed to mitigate HCV transmission among this population. PMID:19422083

    Abstract 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.

    Abstract 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

    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

    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

    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

    The aim of this study was to determine the efficacy of two hepatitis C virus (HCV) real-time PCR assays, the COBAS AmpliPrep/COBAS TaqMan HCV test (CAP/CTM) and the Abbott RealTime HCV test (ART), for predicting the clinical outcomes of patients infected with HCV who received telaprevir (TVR)-based triple therapy or daclatasvir/asunaprevir (DCV/ASV) dual therapy. The rapid virological response rates in patients receiving TVR-based triple therapy were 92% (23/25) and 40% (10/25) for CAP/CTM and ART, respectively. The false omission rate (FOR) of ART was 93.3% (14/15), indicating that CAP/CTM could accurately predict clinical outcome in the early phase. In an independent examination of 20 patients receiving TVR-based triple therapy who developed viral breakthrough or relapse, the times to HCV disappearance by ART were longer than by CAP/CTM, whereas the times to HCV reappearance were similar. In an independent experiment of WHO standard HCV RNA serially diluted in serum containing TVR, the analytical sensitivities of CAP/CTM and ART were similar. However, cell cultures transfected with HCV and grown in medium containing TVR demonstrated that ART detected HCV RNA for a longer time than CAP/CTM. Similar results were found for 42 patients receiving DCV/ASV dual therapy. The FOR of ART was 73.3% (11/15) at week 8 after initiation of therapy, indicating that ART at week 8 could not accurately predict the clinical outcome. In conclusion, although CAP/CTM and ART detected HCV RNA with comparable analytical sensitivity, CAP/CTM might be preferable for predicting the clinical outcomes of patients receiving protease inhibitor-based therapy.

    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).

    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

    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.

    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.

    Background Hepatitis C virus (HCV) is common among people who inject drugs (PWID) on methadoneprogram in Iran (Persia). However, a few PWID on methadone program report willingness to receive HCVtreatment. This study aimed to assess the factors which were associated with willingness to receive HCVtreatment in a group of PWID on methadone program in Iran. Methods We surveyed 187 PWID at seven drops in centers in Tehran, Iran. Details of demographiccharacteristics, drug use, injection, HCV, and drug treatment history were collected using a 25-itemquestionnaire. Participants were serologically tested for the current status of HCV. Findings The study found that 28.3% of the participants were HCV seropositive. In total, 49.1% of theparticipants reported unwillingness to receive HCV treatment. Awareness of current HCV status [odds ratio(OR) = 3.43; 95% confidence interval (CI): 1.33-7.26; P < 0.050]; adequate knowledge of HCV treatmentcenters in the community (OR = 3.9; 95% CI: 1.24-5.38; P < 0.050); participation in an educational programon HCV (OR = 2.9; 95% CI: 2.33-8.56; P < 0.001) and recent participation in the meetings of self-helpgroups (OR = 4.6; 95% CI: 3.43-9.33; P < 0.001) were significantly associated with current willingness toreceive HCV treatment. Conclusion The study results indicate that awareness of HCV status and the provision of adequate HCVeducation via different information centers can be associated with an increased willingness for HCVtreatment among PWID on methadone program. Conducting more research is suggested to assess theefficacy of educational programs and self-help groups in facilitating HCV treatment among PWID onmethadone program. PMID:27882206

    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.

    Hepatic sinusoidal obstruction syndrome (SOS) is a life-threatening syndrome that generally occurs as a complication after hematopoietic stem cell transplantation or, less commonly, after conventional chemotherapy. Regarding SOS in rhabdomyosarcoma patients who received conventional chemotherapy, the doses of chemotherapeutic agents are associated with the development of SOS. Several cases of SOS in rhabdomyosarcoma patients after receiving chemotherapy with escalated doses of cyclophosphamide have been reported. Here, we report on a 9-year-old female with rhabdomyosarcoma who developed severe SOS after receiving chemotherapy consisting of vincristine, actinomycin-D, and a moderate dose of cyclophosphamide. She was treated successfully with defibrotide without sequelae to the liver. PMID:27034141

    Hepatic dysfunction may modify the safety profile and pharmacokinetics of docetaxel in cancer patients, but no validated guideline exists to guide dose modification necessitated by this uncommon comorbidity. We carried out the first prospective study of a personalized dosage regimen for cancer patients with liver dysfunction treated with docetaxel. Weekly dosages were stratified by hepatic dysfunction classification as such: Category 1, normal; Category 2, mild--alkaline phosphatase, aspartate aminotransferase, and/or alanine aminotransferase ≤5× upper limit of normal (ULN), and total bilirubin within normal range; and Category 3, moderate--any alkaline phosphatase, and aspartate aminotransferase or alanine aminotransferase ≤5-10× ULN, and/or total bilirubin ≤1-1.5× ULN. Category 1, 2 and 3 patients received starting dosages of 40, 30, and 20 mg/m(2) docetaxel, respectively. Pharmacokinetics were evaluated on day 1 and 8 of the first treatment cycle, and entered into a multilevel model to delineate interindividual and interoccasion variability. Adverse event evaluation was carried out weekly for two treatment cycles. We found that docetaxel clearance was significantly different between patient categories (P < 0.001). Median clearance was 22.8, 16.4, and 11.3 L/h/m(2) in Categories 1, 2, and 3, respectively, representing 28% and 50% reduced clearance in mild and moderate liver dysfunction patients, respectively. However, docetaxel exposure (area under the concentration-time curve) and docetaxel-induced neutropenia (nadir and the maximum percentage decrease in neutrophil count) were not significantly different between categories. Median area under the concentration-time curve was 1.74, 1.83, and 1.77 mg·h/L in Categories 1, 2, and 3, respectively. The most common Grade 3/4 toxicity was neutropenia (30.0%). An unplanned comparison with the Child-Pugh and National Cancer Institute Organ Dysfunction Working Group grouping systems suggests that the proposed

    Background and Aims There is limited data on hepatitis C (HCV) treatment uptake among people who inject drugs including individuals receiving opioid substitution treatment (OST). We aimed to calculate cumulative HCV treatment uptake, estimate annual treatment rates, and identify factors associated with HCV treatment among individuals who have received OST in Norway. Methods This observational study was based on linked data from The Norwegian Prescription Database and The Norwegian Surveillance System for Communicable Diseases between 2004 and 2013. Both registries have national coverage. From a total of 9919 individuals who had been dispensed OST (methadone, buprenorphine or buprenorphine-naloxone), we included 3755 individuals who had been notified with HCV infection. In this population, dispensions of HCV treatment (pegylated interferon and ribavirin), benzodiazepines, selective serotonin reuptake inhibitors and antipsychotics were studied. Results Among 3755 OST patients notified with HCV infection, 539 (14%) had received HCV treatment during the study period. Annual HCV treatment rates during OST ranged between 1.3% (95% confidence interval [CI] 0.7–2.2) in 2005 and 2.6% (95% CI 1.9–3.5) in 2008 with no significant changes over time. HCV treatment uptake was not associated with age or gender, but associated with duration of active OST (adjusted odds ratio [aOR] 1.11 per year; 95% CI 1.07–1.15), high (> 80%) OST continuity (aOR 1.62; 95% CI 1.17–2.25), and heavy benzodiazepine use (aOR 0.65; 95% CI 0.49–0.87). Conclusions Cumulative HCV treatment uptake among OST patients notified with HCV infection in Norway between 2004 and 2013 was 14%. Annual treatment rates during OST remained unchanged below 3% per year. High continuity of OST over time and absence of heavy benzodiazepine use predicted HCV treatment uptake. Increased awareness for HCV among OST patients is needed as tolerable and efficient directly acting antiviral treatment is being introduced

    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.

    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

    Hepatitis B virus (HBV) prevalence has declined remarkably in children due to nationwide universal vaccination program for HBV in China. However, the persistence of immune response against HBV infection and the optimal time point when a booster vaccination should be performed remain to be elucidated. To assess the persistence and level of antibody against hepatitis B surface antigen (anti-HBs) in a representative population of age 15 and younger who received routine hepatitis B vaccination in Mianyang City, China. A cross-sectional study was conducted in 2011. One thousand five hundred twenty-six children of age 15 and younger who received three doses of 5 μg hepatitis B vaccine series during infancy but did not receive a booster vaccination later were enrolled. Of the 1,526 children, the mean age was 8.2 ± 4.1 and 739 children were male. The median anti-HBs level was 23.0 mIU/mL, and the total percentage of anti-HBs levels ≥10 mIU/mL was 60.9%. With an increase of age, median anti-HBs level, percentage of anti-HBs levels ≥10 mIU/mL, and percentage of anti-HBs levels ≥100 mIU/mL declined remarkably in the early period and reached the lowest level at the age of 3 and then remained relatively stable. The median anti-HBs level, the percentage of anti-HBs levels ≥10 mIU/mL, and the percentage of anti-HBs levels ≥100 mIU/mL in 1- and 2-year-old children were much higher than that in children aged 3-15 (p < 0.05, respectively). Immunity against HBV infection gradually decreased in early ages of children of 15 and younger who received three doses of 5 μg hepatitis B vaccine series during infancy in China. Three dosages of 10 μg hepatitis B vaccine for infants and repeated vaccination or additional booster vaccination for some children at or before age 3 should be provided to get much more powerful immunity to HBV.

    To explore contemporarily genetic and non-genetic determinants of long-term immunological memory to hepatitis B (HB) vaccination, we conducted a case-control study nested in an adolescent cohort of booster recipients who had received primary infantile HB vaccination but with residual anti-HBs titers <10 mIU/mL at 15-18 years of age. High-resolution phenotypes of human leukocyte antigen (HLA)-A, -B, and -DRB1 loci were determined by sequence-specific oligonucleotide probe hybridization. After controlling for pre-booster anti-HBs levels, the absences of HLA-A*02 and -DRB1*08, simply expressed as A*02(-) and -DRB1*08(-), and the presence of B*15 were significantly associated with elevated risks of non-response (post-booster anti-HBs titers<10 mIU/mL) to booster vaccination. The adjusted odds ratios (ORs) were 3.85 (CI, 1.82-8.33), 4.55 (CI, 1.23-16.67), 3.59 (CI, 1.40-9.17), respectively. There was multiplicative synergism between A*02 and B*15 on the risk of non-response to booster vaccination. The multivariate-adjusted ORs for A*02(-)/B*15, A*02(-)/B*15(-), A*02/B*15, and A*02/B*15(-) haplotypes were 20.39 (p=0.0003), 3.29 (p=0.007), 1.32 (p>0.05), and 1.0, respectively. Recent cigarette smoking and/or betel-quid chewing was associated with a 12-fold risk of non-response to booster vaccination. Further comparisons between responders and adolescents who had undetectable post-booster anti-HBs titers (<0.1 mIU/mL) demonstrated similar results. Our results indicated that response to booster HB vaccination as well as long-term immunological responses to HB vaccination are closely related with host genetic factors, and probably modified by recent substance use.

    We compared the effects of 12-week programs of resistance training (RT), high-intensity interval aerobic training (HIAT), and moderate-intensity continuous aerobic training (MICT). The primary goal was to evaluate the therapeutic effects of the exercise modalities for the management of nonalcoholic fatty liver disease (NAFLD). A total of 61 sedentary obese men with NAFLD were randomized into one of the following exercise regimens (RT, HIAT, or MICT). Hepatic fat content was decreased to a similar extent in the RT, HIAT, and MICT groups (−14.3% vs. −13.7% vs. −14.3%) without significant changes in weight and visceral fat. The gene expression levels of fatty acid synthesis were significantly decreased in the subjects’ monocytes. Hepatic stiffness was decreased only in the HIAT group (−16.8%). The stiffness change was associated with restored Kupffer cell phagocytic function (+17.8%) and decreased levels of inflammation such as leptin (−13.2%) and ferritin (−14.1%). RT, HIAT, and MICT were equally effective in reducing hepatic fat content, but only HIAT was effective in improving hepatic stiffness and restoring Kupffer cell function. These benefits appeared to be independent of detectable weight and visceral fat reductions; the benefits were acquired through the modulation of in vivo fatty acid metabolism and obesity-related inflammatory conditions.

    It is unclear whether the rate of weight loss, independent of magnitude, affects whole body protein metabolism and the synthesis and plasma concentrations of specific hepatic secretory proteins. We examined 1) whether lean men losing weight rapidly (starvation) show greater changes in whole body protein kinetics, synthesis, and circulating concentrations of selected hepatic secretory proteins than those losing the same amount of weight more slowly [very low energy diet (VLED)]; and 2) whether plasma concentrations and synthetic rates of these proteins are related. Whole body protein kinetics were measured using [1-(13)C]leucine in 11 lean men (6 starvation, 5 VLED). Fractional and absolute synthetic rates of HDL-apolipoprotein A1 (apoA1), retinol binding protein, transthyretin, alpha(1)-antitrypsin (alpha(1)-AT), and transferrin were measured using a prime-constant intravenous infusion of [(13)C(2)]glycine. Compared with VLED group, the starvation group showed greater increases (at a 5% weight loss) in whole body protein oxidation (P < 0.05); fractional synthetic rates of HDL-apoA1 (25.3 vs. -1.52%; P = 0.003) and retinol binding protein (30.6 vs. 7.1%; P = 0.007); absolute synthetic rates of HDL-apoA1 (7.1 vs. -3.8 mg.kg(-1).day(-1); P = 0.003) and alpha(1)-AT (17.8 vs. 3.6 mg.kg(-1).day(-1); P = 0.02); and plasma concentration of alpha(1)-AT (P = 0.025). Relationships between synthetic rates and plasma concentrations varied between the secreted proteins. It is concluded that synthetic rates of hepatic secreted proteins in lean men are more closely related to the rate than the magnitude of weight loss. Changes in concentration of these secreted proteins can occur independently of changes in synthetic rates, and vice versa.

    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 examine the long-term impact of health counselling among middle-aged men at high risk of CVD. Design An observational study with a 5-year follow-up. Setting and intervention All men aged 40 years in Helsinki have been invited to a visit to evaluate CVD risk from 2006 onwards. A modified version of the North Karelia project risk tool (CVD risk score) served to assess the risk. High-risk men received lifestyle counselling based on their individual risk profile in 2006 and were invited to a follow-up visit in 2011. Subjects Of the 389 originally high-risk men, 159 participated in the follow-up visits in 2011. Based on their follow-up in relation the further risk communication, we divided the participants into three groups: primary health care, occupational health care and no control visits. Main outcome measures Lifestyle and CVD risk score change. Results All groups showed improvements in lifestyles. The CVD risk score decreased the most in the group that continued the risk communication visits in their primary health care centre (6.1 to 4.8 [95% CI −1.6 to −0.6]) compared to those who continued risk communication visits in their occupational health care (6.0 to 5.4 [95% CI −1.3 to 0.3]), and to those with no risk communication visits (6.0 to 5.9 [95% CI −0.5 to 0.4]). Conclusions These findings indicate that individualized lifestyle counselling improves health behaviour and reduces total CVD risk among middle-aged men at high risk of CVD. Sustained improvement in risk factor status requires ongoing risk communication with health care providers. KEY POINTSStudies of short duration have shown that lifestyle changes reduce the risk of cardiovascular disease among high-risk individuals.Sustaining these lifestyle changes and maintaining the lower disease risk attained can prove challenging.Cardiovascular disease (CVD) risk assessment and individualized health counselling for high-risk men, when implemented in primary health care, have the potential

    The effect of lamivudine on chronic coinfection with hepatitis B virus (HBV) in human immunodeficiency virus (HIV)--infected patients was studied prospectively. Nineteen patients with HIV infection, who were receiving an anti-HIV regimen containing lamivudine (150 mg twice daily), and who had replicative chronic HBV infection, were followed for a median of 14 months. Twelve patients' regimens contained protease inhibitors. Serum HBV DNA became undetectable, by means of molecular hybridization, in 14. Seroconversion of hepatitis B e antigen to antibody occurred in 6 of 17 patients, and seroconversion of hepatitis B surface antigen to antibody occurred in 1 of 19. The median serum alanine aminotransferase concentration had decreased by the time of the final evaluation. The median CD4 cell count increased and plasma HIV RNA was undetectable in 10 of 19 patients. Five patients had recurrence of detectable serum HBV DNA despite good compliance with treatment, and 2 mutations related to the resistance of HBV were detected. These patients had a significantly longer duration of treatment (21 versus 13 months; P<.05). In conclusion, resistant strains of HBV emerge at high detectable levels while patients receive anti-HIV regimens containing lamivudine.

    Little is known about the likelihood and degree of hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) seropositive patients with disseminated non-small cell lung cancer (NSCLC) receiving chemotherapy. Between January 2003 and December 2013, all HBsAg seropositive patients with metastatic NSCLC receiving cytotoxic chemotherapy were retrospectively evaluated. The morbidity and mortality of HBV reactivation, risk factors associated with reactivation, as well as the efficacy of preemptive lamivudine were investigated. Of 258 patients who were eligible for the present study, 176 were treated without antiviral prophylaxis and 82 received preemptive lamivudine. Patients without lamivudine prophylaxis had a significantly higher prevalence of HBV reactivation (19.3 vs 6.1 %, p = 0.006) and severe hepatitis attributable to reactivation (11.8 vs 3.7 %, p = 0.034) than those with preemptive lamivudine. However, no significant difference in mortality due to reactivation was noted between patients with or without prophylactic lamivudine (0 vs 2.3 %, p = 0.310). Furthermore, patients who developed HBV reactivation were indentified to have a higher rate of HBeAg seropositivity (74.4 vs 43.4 %, p < 0.001), serum HBV-DNA level of 10(4) copies/ml or greater (76.9 vs 47.9 %, p = 0.001), coexisting liver metastasis (50.0 vs 40.6 %, p = 0.033) and treatment with more than 4 cycles of chemotherapy (56.4 vs 39.3 %, p = 0.046) than those who did not experienced reactivation. The current study has demonstrated that preemptive lamivudine significantly reduced the prevalence of HBV reactivation in HBsAg seropositive patients with metastatic NSCLC receiving systemic chemotherapy.

    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.

    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.

    The International Agency for Research on Cancer has declared smoking to be a risk factor for hepatocellular carcinoma (HCC). However, passive exposure to cigarette smoke and use of noncigarette tobacco products on the risk of HCC has not been examined. Therefore, we evaluated the independent effects of different types of smoking exposure along with multiple risk factors for HCC and determined whether the magnitude of smoking was modified by other risk factors in men and women. We conducted a case-control study at The University of Texas M. D. Anderson Cancer Center where 319 HCC patients and 1,061 healthy control subjects were personally interviewed for several HCC risk factors. Multivariate logistic regression analysis was performed to estimate the adjusted odds ratio (AOR) and 95% confidence interval (CI) for each potential risk factor. Use of smokeless tobacco (chewing tobacco and snuff), cigars, pipes and passive smoking exposure were not related to HCC among noncigarette smokers. However, regular cigarette smoking was associated with HCC in men: AOR, 1.9 (95% CI, 1.1–3.1). Heavy alcohol consumption was associated with HCC in women: AOR, 7.7 (95% CI, 2.3–25.1). Cigarette smoking interacted synergistically with chronic infection of hepatitis C virus in men: AOR, 136.3 (95% CI, 43.2–429.6) and with heavy alcohol consumption in women: AOR, 13.7 (95% CI, 3.2–57.9). We conclude that sex differences were observed in HCC relationship with cigarette smoking and alcohol consumption. Controlling for smoking exposure might be a prudent approach to the prevention of HCC, especially in patients with chronic viral hepatitis infections. PMID:18688864

    Abstract Introduction and Aims Controlling behaviours are highly prevalent forms of non‐physical intimate partner violence (IPV). The prevalence of perpetrating controlling behaviours and technology‐facilitated abuse (TFA) was compared by men receiving substance use treatment in England (n = 223) and Brazil (n = 280). Factors associated with perpetrating these behaviours towards their current/most recent partner and their association with other types of IPV were explored. Design and Methods Secondary analysis from two cross‐sectional studies was performed. Data on socio‐demographic characteristics, infidelity, IPV perpetration and victimisation, adverse childhood experiences (ACE), attitudes towards gender relations and roles, substance use, depressive symptoms and anger expression were collected. Results Sixty‐four percent (143/223) and 33% (73/223) of participants in England and 65% (184/280) and 20% (57/280) in Brazil reported controlling behaviours and TFA, respectively, during their current/most recent relationship. Excluding IPV victimisation from the multivariate models; perpetrating controlling behaviours was associated with a higher number of ACE, higher anger expression (England) and severe physical IPV perpetration (Brazil), and perpetrating TFA was associated with younger age. Including both IPV victimisation and perpetration in the multivariate models; perpetrating controlling behaviour was associated with experiencing a higher number of ACE, higher anger expression (England), emotional IPV victimisation (England) and experiencing controlling behaviour from a partner (England). The perpetration of TFA was associated with younger age and experiencing TFA from a partner. Conclusions Technological progress provides opportunities for perpetrators to control and abuse their partners. Controlling behaviours and TFA should be addressed to reduce IPV perpetration by males in substance use treatment. [Gilchrist G, Canfield M,Radcliffe P, d

    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

    We conducted a revaccination study to investigate the short-term response to booster hepatitis B (HB) vaccination in seronegative adolescents who had received primary infantile HB vaccination. A booster dose of recombinant HB vaccine was administered to 395 adolescents 15-18 years of age whose serum titers of antibody against hepatitis B surface antigen (HBsAg) (anti-HBs) were <10 mIU/mL. Seventy-seven percent of the booster recipients converted to anti-HBs seropositivity (postbooster titers> or =10 mIU/mL). As compared with adolescents who had undetectable prebooster anti-HBs titers (<0.1 mIU/mL), the seropositive rates and geometric mean titers (GMTs) of 2-month and 1-year postbooster were significantly higher for those of prebooster titers of 0.1-0.9 and 1.0-9.9 mIU/mL (all p<0.0001). Postbooster titers declined significantly more rapidly for those with undetectable prebooster anti-HBs titers than for those with prebooster titers of 0.1-0.9 and 1.0-9.9 mIU/mL. Our observations indicate that a booster dose of HB vaccine maybe unable to induce sufficient immunological response in adolescents who had undetectable residual anti-HBs titers.

    Little is known about the optimal management of patients with chronic hepatitis B (CHB) who develop drug resistance. The aim of this study was to investigate the effectiveness of different drug regimens in chronically HBV-infected patients. HBV viral load was determined using a bDNA assay and the substitutions in HBV-DNA were studied by polymerase sequencing test. The study involved 38 patients who experienced a therapeutic failure to lamivudine (LAM). The sequential treatments used were: LAM + adefovir (ADV), LAM + tenofovir (TDF), entecavir (ETV) monotherapy, ADV monotherapy and TDF monotherapy. Similar activity against HBV replication was observed with all drug regimens. Of the patients treated with LAM, 44% developed resistance mutations. The rt M204I mutation was observed more frequently. Sequential ADV add-on LAM and TDF therapy induced the appearance of resistance in 3/18 (16.6%) and in 1/8 (5.5%) treated patients, respectively. Genotype D was the most prevalent (78.9%), followed by genotype A (13%), genotype E (5.2%) and genotype C (2.6%). Our study showed that baseline serum HBV DNA is an important predictor of virologic response and that virologic breakthrough is significantly associated with the insurgence of genotypic resistance.

    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

    Abstract 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

    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), 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 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.

    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

    Little is known about the longitudinal course of hepatitis B virus (HBV) load and its relationship with the development of hepatocellular carcinoma (HCC). We conducted a case-cohort study nested within a cohort of 2874 HBV surface antigen-positive male Taiwanese government employees aged 30 years or older. HBV genotype and DNA levels (i.e. viral load) were tested using polymerase chain reaction-based assays on plasma samples from 112 cases and 1031 non-cases. Prediagnostic plasma levels of HBV DNA were measured in multiple samples collected from each man (total 7706 samples), taken over periods of up to 16 years before diagnosis. Baseline viral load influenced HBV genotype-specific HCC risks and predicted the persistence of high viral load (>/=4.39 log copies/ml) that can cause HCC. Moderate to high tracking of viral load was observed within 9 years. Hepatitis B e antigen (P < 0.0001), genotype C HBV infection (P = 0.0369) and longitudinal alanine aminotransferase (ALT) elevation (defined as ALT abnormality in >/=50% of the visits) (P = 0.0005) were positively related to longer duration of persistence for high viral load. After multivariate adjustment, HBV genotype C [odds ratio (OR) = 5.97, 95% confidence interval (CI) = 3.44-10.34], high viral load detected at >/=50% of the visits (compared with sustained low viral load: OR = 5.04, 95% CI = 2.31-11.00) and longitudinal ALT elevation (compared with sustained normal ALT levels: OR = 2.84, 95% CI = 1.46-5.51) accounted for 43.5, 57.2 and 24.9% of HCCs, respectively. The results suggest that maintenance of viral load <4.39 log copies/ml was associated with sustained normalization of ALT levels and decreased risk of HCC.

    Abstract 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 study was carried out to investigate the effects of different levels of clove bud (Syzygium aromaticum) powder and vitamin E on serum lipid profile, enzyme activities and antioxidant indices, as well as hepatic biochemical and histological alterations in laying hens receiving different n-6 to n-3 ratios. A total of 160 laying hens, 43 weeks of age, were allotted to 8 experimental diets with 5 cages of 4 birds each. Dietary treatments consisted of two ratios of n-6 to n-3 (16.71 and 2.35), three levels of clove bud (0.0, 2.0 and 4.0 g/kg) and a high vitamin E level (200 mg/kg, as a positive control in each level of n-6 to n-3 ratio) in a 2 × 4 factorial arrangement during 70 days of the experiment. Results showed that a decline in the n-6 to n-3 ratio led to a reduction in serum cholesterol concentration (p < 0.05) and an increase in serum HDL content (p < 0.05). Additionally, decreasing n-6 to n-3 ratio and increasing clove bud level caused a remarkable decline in serum aspartate aminotransferase (p < 0.05 and p < 0.001) and alanine aminotransferase (p < 0.05 and p < 0.05) enzyme activities. Furthermore, total antioxidant capacity (p < 0.05 and p < 0.001) as well as serum vitamin E concentration (p < 0.05 and p < 0.001) was decreased and enhanced by low n-6 to n-3 ratio diets (LRD) and clove bud powder respectively. Decreasing the n-6 to n-3 ratio lowered hepatic lipid (p < 0.05) and glycogen contents (p < 0.01) as well as tissue integrity (p < 0.05), and raised liver MDA concentration (p < 0.001), markedly. Nevertheless, increments in clove bud content led to a reduction (p < 0.01) in liver relative weight (p < 0.05) and hepatic fat vacuole numbers. In general, the best synergistic responses on modulating of blood lipids and serum enzyme activities were observed when the highest level of clove bud was supplemented in the diets with low n-6 to n-3 ratio. Likewise, antioxidant indices were improved by administration of

    The objective of this study was to characterise the status of health-related quality of life (HRQOL) in Japanese men with late-onset hypogonadism (LOH) treated with testosterone replacement therapy (TRT). HRQOL in 69 consecutive Japanese men with LOH undergoing TRT for at least 6 months was prospectively evaluated before and 6 months after the initiation of TRT using the Medical Outcomes Study 8-Item Short-Form Health Survey (SF-8). All eight-scale scores except for bodily pain (BP) in the 69 patients at 6 months after the introduction of TRT significantly improved compared with those before TRT; however, all scale scores except for BP in the 69 patients were significantly inferior to those in age-matched Japanese controls irrespective of the timing of SF-8. Multivariate analyses of several parameters revealed that both age and Aging Male Symptom (AMS) score had an independent impact on mental health (MH), despite the lack of an independent association between any score and the remaining factors examined. TRT appeared to significantly improve the status of HRQOL in men with LOH; however, even after the introduction of TRT, HRQOL associated with MH remained significantly impaired in elderly men and/or those with a high AMS score.

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: Recurrence of Hepatitis B Virus infection in patients undergoing liver transplanted (LT) is a serious and often fatal problem. Lamivudine (LAM) and Hepatitis B Immunoglobulin (HBIG) are widely used to manage hepatitis B recurrence after liver transplantation. However, the outcomes in patients are less elucidated. Objectives: The current study aimed to evaluate the YMDD motif mutations profile among the patients undergoing LT infected with HBV and treated with LAM/HBIG at least for one year. Patients and Methods: Thirty patients with liver transplantation due to HBV were enrolled, while DNA level remained under detection limit of 50 IU/mL before transplantation and abnormal higher levels of liver enzymes after LT. The HBV genome detection was performed by two different Polymerase Chain Reaction methods following viral quantification by commercial Real-Time PCR. HbsAg detection, besides liver function tests were conducted as complementary assays. To assess nucleotide analogue mutations, the major part of polymerase gene (aa 80 - 240) was amplified by Nested-PCR, introduced to sequencing and subjected to phylogenetic analysis. Results: Totally, according to the laboratory criteria there were 13 cases with detectable HBV genome, while the mean liver enzyme levels were higher in recurrent patients and HBsAg was detected only in four out of the 13 cases. Phylogenetic analysis demonstrated that all isolated genomes belonged to genotype D. Critical M204I mutation, as a proof for resistance to LAM, was detected among 46% of the subjects and natural entecavir resistance (S202I) was also distinguished in one subject. Viral quantification showed higher titer in LAM resistant group in comparison to the group with undetectable drug resistance mutant (P > 0.05). Conclusions: Although the patients carrying M204I mutation were more likely to show lack of responses to LAM therapy, LAM replacing by other nucleoside/tide analogs plus HBIG maybe still effective in

    This study aimed to assess the seroprevalence and risk factors for hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV-1 infections among injecting drug users (IDU) in New Mexico. Serological and behavioural surveys were conducted in conjunction with street-based outreach, education and HIV counselling and testing. High rates of antibody positivity for HCV (82.2%) and HBV (61.1%), and a low rate for HIV (0.5%) were found. In multivariate analyses, both HBV and HCV infection were positively associated with increasing age, increasing years of injection and heroin use. Receipt of a tattoo in prison/jail was associated with HBV (odds ratio = 2.3, 95% confidence interval 1.4, 3.8) and HCV (OR = 3.4, 95% CI = 1.6, 7.5) infections. Prevention of bloodborne pathogens among IDUs should focus on young users, early in their drug use experience. Studies examining the relationship between tattooing and HBV and HCV infection are needed as are efforts to promote sterile tattooing, in prisons and elsewhere.

    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

    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.

    We investigated the relationship between microbial translocation, immune activation, and liver disease in human immunodeficiency virus (HIV)/hepatitis B virus (HBV) coinfection. Lipopolysaccharide (LPS), soluble CD14, CXCL10, and CCL-2 levels were elevated in patients with HIV/HBV coinfection. Levels of LPS, soluble CD14, and CCL-2 declined following receipt of HBV-active combination antiretroviral therapy (cART), but the CXCL10 level remained elevated. No markers were associated with liver disease severity on liver biopsy (n = 96), but CXCL10, interleukin 6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor α, and interferon γ (IFN-γ) were all associated with elevated liver enzyme levels during receipt of HBV-active cART. Stimulation of hepatocyte cell lines in vitro with IFN-γ and LPS induced a profound synergistic increase in the production of CXCL10. LPS may contribute to liver disease via stimulating persistent production of CXCL10.

    A 70-year-old man who suffered from chronic hepatitis C was infected with HCV genotype 1 and exhibited a high viral load. He had hypertension and had consumed the equivalent of 50 g of ethanol per day. He was treated with pegylated interferon and ribavirin. After 51 weeks, he developed an unsteady gait while walking and demonstrated Barre's sign on the right foot and a headache. Contrast computed tomography showed a subdural hematoma with a mass effect. The patient was treated with drainage and aspiration surgery via a burr hole. Following the drainage procedure, there were no neurological sequelae. Treatment with pegylated interferon and ribavirin was discontinued. Fortunately, a sustained virological response was achieved.

    There is now evidence that repeated administration of interferon-alpha (IFN-alpha) to patients with chronic active hepatitis and cancers induces depressive symptoms. There is also evidence that induction of the cytokine network modulates the serotonergic system and that major depression is related to activation of the cytokine network and disturbances in the serotonergic metabolism. The aims of this study were to examine the effects of IFN-alpha-based immunotherapy on the development of depressive symptoms in relation to its effects on plasma tryptophan and kynurenine and serum serotonin (5-HT). Eighteen patients affected by chronic active hepatitis C were treated with IFN-alpha (3-6 million units subcutaneously three to six times a week for 6 months) and had measurements of the previous parameters before starting immunotherapy and 2, 4, 16, and 24 weeks later. Severity of depression and anxiety were measured with the Montgomery-Asberg Depression Rating Scale (MADRS) and the Hamilton Rating Scale for Anxiety (HAM-A) scale, respectively. Immunochemotherapy with IFN-alpha (1) significantly increased the MADRS and HAM-A scores and serum kynurenine concentrations and (2) significantly reduced plasma tryptophan and serum 5-HT concentrations. IFN-alpha-based immunotherapy significantly increased the kynurenine per tryptophan quotient, which estimates the activity of indoleamine 2,3-dioxygenase, the major tryptophan-catabolizing enzyme, which is induced by IFNs. There are significant relationships between the IFN-alpha-induced changes in the MADRS score and serum kynurenine (positive) and 5-HT (negative) concentrations. Immunotherapy with IFN-alpha significantly increases the severity of depressive symptoms. The latter is related to changes in the serotonergic system, such as depletion of serum 5-HT and induction of the catabolism of tryptophan to kynurenine. It is suggested that the IFN-alpha-induced changes in the serotonergic turnover could play a role in the

    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.

    Background Female injection drug users (IDUs) may report differences in injection behaviours that put them at greater risk for hepatitis C virus (HCV). Few studies have examined these in association with HCV incidence. Methods Longitudinal data from a cohort of 417 HCV-uninfected IDU aged 30 or younger were analysed. Cox proportional hazards was used to model female sex as a predictor of new HCV infection. General estimating equation (GEE) analysis was used to model female sex as a predictor of HCV-associated risk behaviour prospectively. Results Women were significantly more likely than men to become infected with HCV during study follow-up (HR 1.4, p<0.05), and were also more likely than men to report high-risk injecting behaviours, especially in the context of sexual and injecting relationships. Sex differences in injecting behaviours appeared to explain the relationship between sex and HCV infection. Conclusions Young women’s riskier injection practices lead to their higher rates of HCV infection. Further study on the impact of intimate partnership on women’s risk behaviour is warranted.

    Monitoring hepatitis C virus (HCV) kinetics during antiviral treatment is recommended for determining the best form of treatment management. We compared the measurement of HCV RNA by two Real-time PCR assays during the first 12weeks phase of telaprevir in combination with pegylated interferon α2b and ribavirin treatment for chronic hepatitis C patients. The viral kinetics of 65 patients with HCV genotype 1b was assessed. HCV RNA was tested at baseline, on day 3, and every week from 1 to 12 by both the first-generation Roche COBAS® AmpliPrep/COBAS® TaqMan® HCV (CAP/CTM) assay and the Abbott RealTime HCV (ART) assay. A total of 910 serum samples were obtained from the 65 patients. Of these, 168 (28.5%) of the 590 samples HCV RNA negative by CAP/CTM were positive by ART. In contrast, 17 (3.9%) of the 439 samples HCV RNA negative by ART were positive by CAP/CTM. The rates of HCV RNA negativity by ART at weeks 3, 4, and 5 were significantly lower than those by CAP/CTM (21.5% vs. 50.8%, 36.9% vs. 70.8% and 44.6% vs. 81.5%; P<0.001, P<0.0001 and P<0.05, respectively). Although the ART is superior for the determination of HCV RNA negativity, the predictive value of detectable HCV RNA for non-sustained virological response (non-SVR) by CAP/CTM is higher than by ART at weeks 4, 6, and 8. We also found that 16 (24.6%) by CAP/CTM and 28 (43.1%) by ART had a reappearance of residual HCV RNA during the telaprevir treatment period. However, the reappearance of residual HCV RNA was not associated with non-SVR. In conclusion, a significant difference was found between the two real-time PCR assays for the assessment of virological response based on undetectable HCV RNA.

Para eliminarlos, se requiere tratamiento con corticoides y fármacos citotóxicos. Métodos: describimos el caso del uso de rituximab en hemofilia adquirida refractaria al tratamiento convencional en un hombre de 63 años con infección crónica por el virus de la hepatitis C y que estaba recibiendo tratamiento con interferón pegilado a-2a y ribarivina. Resultados: tras 21 semanas de tratamiento antivírico, el paciente fue ingresado en el hospital por un gran hematoma en la musculatura abdominal. La concentración de factor VIII era nula y el título de inhibidor fue de 345 unidades Bethesda. Se administró tratamiento inmunosupresor oral con metilprednisolona y ciclofosfamida durante 1 mes, con escasa mejoría. Así pues, se sustituyó la ciclofosfamida por una dosis semanal de rituximab intravenoso. Dos meses después, la concentración de factor VIII se normalizó y el título de inhibidor era indetectable. Conclusión: Rituximab puede ser útil en el tratamiento de la hemofilia adquirida resistente al tratamiento estándar.

    Infectious and parasitic diseases affecting women during their reproductive age may result in vertical transmission. The aim of this study was to determine the seroprevalence for TORSCH among pregnant women receiving care at a university hospital. Records of 574 pregnant women who received medical attention from January 2006 to December 2007 were assessed. The mean age was 27.2 ± 6.5 years ranging from 13 to 44. The results of the immunodiagnostic tests were: 62.0% (345/556) for IgG and 3.4% (19/556) for IgM anti-T. gondii; 93.1% (433/465) for IgG and 0.6% (3/465) for IgM anti-rubella; 0.9% (5/561) for VDRL; 1.8% (10/554) for HBsAg; 0.7% (4/545) for anti-HCV and 2.1% (11/531) for HIV. In conclusion, the results of immunodiagnostic tests for the TORSCH panel among pregnant women attending a perinatal service of a university hospital are in agreement with those reported by previous studies and by governmental sources.

    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

HibMenCY-TT is the first meningococcal vaccine available for use in the USA that can be administered to infants as young as 6 weeks of age. In a randomized, controlled, phase III clinical trial, the HibMenCY-TT vaccine, administered to infants at 2, 4, 6 and 12-15 months of age, was immunogenic against MenC and MenY, and met the prespecified criteria for immunogenicity. Anti-PRP antibodies, which have been shown to correlate with protection against Hib invasive disease, were also induced in the infants who received the HibMenCY-TT vaccine, with induced levels of this antibody noninferior to those occurring in the control group of infants who received a Hib tetanus toxoid conjugate vaccine at 2, 4, and 6 months and a single dose of Hib conjugated to N. meningitidis outer membrane protein at 12-15 months. In several randomized, controlled clinical trials, HibMenCY-TT was coadministered with vaccines that are routinely administered to infants and toddlers in the USA. These vaccines included: diphtheria and tetanus toxoids and acellular pertussis adsorbed, hepatitis B (recombinant) and inactivated poliovirus vaccine combined; 7-valent Streptococcus pneumoniae polysaccharide conjugate vaccine; measles, mumps and rubella vaccine; and varicella vaccine. Coadministration of these vaccines did not interfere with the immunogenicity of the HibMenCY-TT vaccine. Similarly, immune responses to the coadministered vaccines were not affected by the HibMenCY-TT vaccine. The tolerability profile of the HibMen

    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.

  4. Mortality and morbidity among military personnel and civilians during the 1930s and World War II from transmission of hepatitis during yellow fever vaccination: systematic review.

    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.

    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.

    De novo hepatitis B infection in patients receiving liver transplants from hepatitis B core antibody-positive donors is well known, but the effective prevention strategy has not been well established. In our hospital, recipients receive hepatitis B immunoglobulin monotherapy if they are hepatitis B surface antigen negative at the time of transplant and are receiving a liver from a hepatitis B core antibody-positive donor. Since August 2006, we have had 4 patients who were naïve to hepatitis B virus and received a hepatitis B core antibody-positive graft. Two patients died of other causes, and 2 patients, who had liver transplant in October 2006 and October 2009, developed de novo hepatitis B. Both patients were tested annually for serum hepatitis B surface antigen as part of routine visit. Tests were negative; however, both patients recently became hepatitis B surface antigen positive. Other laboratory results, including liver function test, were unremarkable, except HBsAb titer was undetectable even though hepatitis B immunoglobulin monotherapy had been administrated 2 months previously in both patients. The patients had hepatitis B virus DNA levels of 3.07E+08 copies/mL and 1.51E+08 copies/mL. We suggest that additional prophylactic therapies above hepatitis B immunoglobulin monotherapy are needed for these recipients.

    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.

    Viral hepatitis is a serious health problem all over the world. However, the reduction of the morbidity and mortality due to vaccinations against hepatitis A and hepatitis B has been a major component in the overall reduction in vaccine preventable diseases. We will discuss the epidemiology, vaccine development, and post-vaccination effects of the hepatitis A and B virus. In addition, we discuss attempts to provide hepatitis D vaccine for the 350 million individuals infected with hepatitis B globally. 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.

  8. Liver transplantation for hepatitis B: what is the best hepatitis B immune globulin/antiviral regimen?

    PubMed

    Angus, Peter W; Patterson, Scott J

    2008-10-01

    1. Prophylaxis using the combination of lamivudine and high-dose intravenous hepatitis B immunoglobulin (approximately 10,000 IU monthly) reduces the long-term risk of recurrence of hepatitis B in hepatitis B surface antigen-positive transplant recipients to 5% to 10%. However, this therapy is expensive and inconvenient for patients. 2. Recent studies have shown that similar results can be obtained, at far less cost, with much lower doses of intramuscular hepatitis B immune globulin (400-800 IU monthly) in combination with pretransplant and posttransplant lamivudine therapy. 3. The development of lamivudine resistance pre-transplant can lead to hepatic decompensation and increases the risk of posttransplant recurrence in patients receiving hepatitis B immune globulin/lamivudine prophylaxis. Newer nucleos(t)ide analogues with lower resistance rates such as entecavir, adefovir, and tenofovir should therefore replace lamivudine in hepatitis B prophylaxis. 4. Combination therapy with these newer agents and low-dose intramuscular hepatitis B immune globulin is likely to be the most cost effective hepatitis B immune globulin-containing regimen for the prevention of hepatitis B recurrence post-transplant. 5. Some form of hepatitis B virus prophylaxis needs be continued indefinitely post-transplant. However, the use of antivirals with very low rates of drug resistance will make it possible to stop hepatitis B immune globulin therapy in many patients currently receiving hepatitis B immune globulin/nucleos(t)ide combination therapy.

    2011-12-01

    Men who have sex with men (MSM) have increased rates of human immunodeficiency virus (HIV) infection and sexually transmitted diseases (STDs) compared with demographically matched controls. The reasons for the disproportionate infection burden are complex, including biological, behavioral, and sociocultural factors. HIV and syphilis may often be coprevalent among MSM. The use of nucleic acid amplification testing has enhanced the ability to detect frequently asymptomatic gonococcal and chlamydial infections of the rectum and other sites. Lymphogranuloma proctitis outbreaks among MSM were noted in the developed world several years ago but have not been common recently. MSM are at increased risk for viral hepatitis and anal human papillomavirus disease. Preventive interventions include vaccination for the former and anal cytologic screening for the latter. Because of the diverse ways in which MSM may be exposed to STDs, it is essential for clinicians to obtain a thorough sexual history in a culturally competent manner.

    Fifty-eight adult patients with acute leukemia were screened at the onset of the disease for hepatitis B antigen (HBSAg) in the serum, and during the course of the disease for the development of hepatitis B. One patient had a positive test for HBSAg by the radioimmunoassay technique only at the time leukemia was diagnosed; this patient had received transfusions some years before. In six patients icteric hepatitis B developed; five recovered completely and one died of leukemia during the course of hepatitis. All patients in whom hepatitis developed had received transfusions as a part of supportive therapy for leukemia. The hepatitis risk for patients who received transfusions of blood found to be negative for HBSAg by counterimmunoelectrophoresis was 0.26 percent per unit of blood administered. PMID:1054615

    Health-related quality-of-life (HRQOL) after a radical prostatectomy (RP) or external beam radiation therapy (EBRT) has not been studied in conjunction with oncological outcomes in relation to disease risk stratification. Moreover, the long-term outcomes of these treatment approaches have not been studied. We retrospectively analyzed oncological outcomes between consecutive patients receiving RP (n=86) and EBRT (n=76) for localized prostate cancer. HRQOL and functional outcomes could be assessed in 62 RP (79%) and 54 EBRT (79%) patients over a 3-year follow-up period (median: 41 months) using the Medical Outcomes Study Short Form-36 (SF-36) and the University of California Los Angeles Prostate Cancer Index (UCLA PCI). The 5-year biochemical progression-free survival did not differ between the RP and EBRT groups for low-risk (74.6% vs. 75.0%, P=0.931) and intermediate-risk (61.3% vs. 71.1%, P=0.691) patients. For high-risk patients, progression-free survival was lower in the RP group (45.1%) than in the EBRT group (79.7%) (P=0.002). The general HRQOL was comparable between the two groups. Regarding functional outcomes, the RP group reported lower scores on urinary function and less urinary bother and sexual bother than the EBRT group (P<0.001, P<0.05 and P<0.001, respectively). With risk stratification, the low- and intermediate-risk patients in the RP group reported poorer urinary function than patients in the EBRT group (P<0.001 for each). The sexual function of the high-risk patients in the EBRT group was better than that of the same risk RP patients (P<0.001). Biochemical recurrence was not associated with the UCLA PCI score in either group. In conclusion, low- to intermediate-risk patients treated with an RP may report relatively decreased urinary function during long-term follow-up. The patient's HRQOL after treatment did not depend on biochemical recurrence.

    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.

    2013-10-26

    Autoimmune hepatitis is a disease of the hepatic parenchyma that can present in acute or chronic forms. In common with many autoimmune diseases, autoimmune hepatitis is associated with non-organ-specific antibodies in the context of hepatic autoimmunity. This dichotomy has made definition of a unifying hypothesis in the pathophysiology of the disease difficult, although data from the past 8 years have drawn attention to the role of regulatory T cells. Several triggers have been identified, and the disease arises in genetically susceptible individuals. Clinical and biochemical remission is achievable in up to 85% of cases. For the remaining patients, alternative immunosuppression strategies are an option. Liver transplantation provides an excellent outcome for patients with acute liver failure or complications of end-stage liver disease, including hepatocellular carcinoma. Variant or overlapping syndromes are worthy of consideration when unexpected disease features arise.

  10. Hepatitis E.

    Hepatitis E, previously known as enterically transmitted non-A, non-B hepatitis, is an infectious viral disease with clinical and morphologic features of acute hepatitis. Its causative agent, hepatitis E virus, consists of small, 32- to 34-nm diameter, icosahedral, nonenveloped particles with a single-stranded, positive-sense, 7.5-kb RNA. The virus has two main geographically distinct strains, Asian and Mexican; recently, novel isolates from nonendemic areas and a genetically related swine HEV have been described. HEV is responsible for large epidemics of acute hepatitis and a proportion of sporadic hepatitis cases in the Indian subcontinent, southeast and central Asia, the Middle East, parts of Africa, and Mexico. The virus is excreted in feces and is transmitted predominantly by fecal-oral route, usually through contaminated water. Person-to-person transmission is uncommon. Clinical attack rates are the highest among young adults. Recent evidence suggests that humans with subclinical HEV infection and animals may represent reservoirs of HEV; however, further data are needed. Diagnosis of hepatitis E is usually made by detection of specific IgM antibody, which disappears rapidly over a few months; IgG anti-HEV persists for at least a few years. Clinical illness is similar to other forms of acute viral hepatitis except in pregnant women, in whom illness is particularly severe with a high mortality rate. Subclinical and unapparent infections may occur; however, chronic infection is unknown. No specific treatment is yet available. Use of clean drinking water and proper sanitation is currently the most effective method of prevention. Passive immunization has not been proved to be effective, and recombinant vaccines for travelers to disease-endemic areas and for pregnant women currently are being developed.

  16. Prostate cancer in men of African origin.

    Men of African origin are disproportionately affected by prostate cancer: prostate cancer incidence is highest among men of African origin in the USA, prostate cancer mortality is highest among men of African origin in the Caribbean, and tumour stage and grade at diagnosis are highest among men in sub-Saharan Africa. Socioeconomic, educational, cultural, and genetic factors, as well as variations in care delivery and treatment selection, contribute to this cancer disparity. Emerging data on single-nucleotide-polymorphism patterns, epigenetic changes, and variations in fusion-gene products among men of African origin add to the understanding of genetic differences underlying this disease. On the diagnosis of prostate cancer, when all treatment options are available, men of African origin are more likely to choose radiation therapy or to receive no definitive treatment than white men. Among men of African origin undergoing surgery, increased rates of biochemical recurrence have been identified. Understanding differences in the cancer-survivorship experience and quality-of-life outcomes among men of African origin are critical to appropriately counsel patients and improve cultural sensitivity. Efforts to curtail prostate cancer screening will likely affect men of African origin disproportionately and widen the racial disparity of disease.

    Objective Vertical transmission of the hepatitis B virus (HBV) is the commonest mode of infection and can be prevented with immunoprophylaxis of the infant and antiviral therapy in the mother. Our aim was to review a cohort of subjects with HBV in pregnancy to determine the prevalence of active disease or high HBV-DNA levels that required treatment to prevent transmission, and to review the management of mothers and infants. Methods A retrospective case-note review was conducted of all the HBV-infected pregnant women and their infants who attended the Newcastle obstetric services from 2007 to 2011. Results There were 113 pregnancies in 81 women (median age 28 years; 15% hepatitis B e antigen (HBeAg) positive) during 2007–11. 71% of mothers were first diagnosed with HBV during pregnancy. The mothers were born in 28 different countries. 69% of mothers had an HBV-DNA level less than 2000 IU/mL and 13% had HBV-DNA levels greater than 1.0×107 IU/mL so would be eligible for antiviral therapy to prevent transmission to the infant. 9% had active eAg-positive HBV and 3% had active eAg-negative HBV requiring treatment. All infants born to HBeAg-positive mothers received hepatitis B immunoglobulin (HBIG) appropriately and 76% of infants received a full HBV vaccination course. One infant born to an HBeAg-negative mother was hepatitis B surface antigen positive 1 year post-delivery. Conclusions One in six women had active HBV requiring treatment or high HBV-DNA levels that would benefit from antiviral treatment to reduce the transmission risk. HBIG was administered appropriately but completion of the vaccination course was suboptimal. PMID:24683447

  1. [Viral hepatitis of enteric origin].

    Hepatitis viruses of oral-fecal origin are responsible for a high morbidity and mortality throughout the world, even if they never result in chronic hepatitis. Two viruses, the virus of hepatitis A (VHA) and of hepatitis E (VHE) are at present the cause of severe viral hepatitis of enteric origin. Water is the principle vector in the spread of these viruses. However, the epidemiological aspects vary according to the pathogenic agent. VHA is excreted in a highly concentrated form in the feces for a relatively short period of time. Since it resists in an exterior environment, the virus remains infectious for a long time. VHE is excreted for a short period of time and in low concentrations. The viral particles are fragile in vitro and their variability in the environment is little known. The possible reservoir role of certain animals has been envisaged. Epidemics arise especially in countries suffering from poor hygiene and massive water pollution. Hepatitis A should no longer be considered a benign disease of childhood. The progress made in hygiene and economic development in industrialized countries have made contacts with this virus scarce, rendering the populations more receptive to it and epidemics more widespread. When the sickness occurs later in life, infection is more often symptomatic and can be serious, resulting sometimes long-term indisposition. Hepatitis E has a vast distribution throughout the world and manifests itself either in epidemic or endemic-sporadic form in many poor countries. In developed countries, it comes about mostly as a result of imported pathology, even if there exists a "substratum" of infection in these areas. The main clinical aspects, such as we were able to study them in 39 cases of military men from Tchad, Guyana and Somalia, are comparable to those of hepatitis A. The reasons for the particular gravity of symptoms in pregnant women are unknown. These affections have no specific treatment. In the field of prevention, vaccination

    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.

  3. HBeAg Seroconversion in HBeAg-Positive Chronic Hepatitis B Patients Receiving Long-Term Nucleos(t)ide Analog Treatment: A Systematic Review and Network Meta-Analysis

    Background HBeAg seroconversion is an important intermediate outcome in HBeAg-positive chronic hepatitis B (CHB) patients. This study aimed to compare the effect of nucleos(t)ide analogs (NAs) on HBeAg seroconversion in treating CHB with lamivudine, adefovir, telbivudine, entecavir, and tenofovir. Methods Network meta-analysis of NA treatment-induced HBeAg seroconversion after 1–2 years of treatment was performed. In addition, NA treatment-induced HBeAg seroconversion after 3–5 years of treatment was systematically evaluated. Results A total of 31 articles were included in this study. Nine and five studies respectively reporting on 1- and 2-year treatment were included in our network meta-analysis. In addition, 6, 5, and 5 studies, respectively reporting on 3-, 4-, and 5-year treatment were included in our systematic evaluation. Telbivudine showed a significantly higher HBeAg seroconversion rate after a 1 year treatment period compared to the other NAs (odds ratio (OR) = 3.99, 95% CI 0.68–23.6). This was followed by tenofovir (OR = 3.36, 95% CI 0.70–16.75). Telbivudine also showed a higher seroconversion rate compared to the other NAs after a 2 year treatment period, (OR = 1.38, 95% CI 0.92–2.22). This was followed by entecavir (OR = 1.14, 95% CI 0.72–1.72). No significant difference was observed between spontaneous induction and long-term telbivudine treatment-induced HBeAg seroconversion. However, entecavir and tenofovir treatment-induced HBeAg seroconversions were significantly lower than spontaneous seroconversion. Conclusion Long-term treatment with potent anti-HBV drugs, especially tenofovir and entecavir, may reduce HBeAg seroconversion compared with spontaneous HBeAg seroconversion rate. Telbivudine treatment, whether short term or long term, is associated with higher HBeAg seroconversion compared with the other NAs. However, the high rates of drug resistance likely limit the application of telbivudine. PMID:28107377

    The purpose of this study was to examine the acute effects of alcohol on aggressive behavior in men and women in a laboratory setting. Participants were 526 (261 men and 265 women) healthy social drinkers between 21 and 35 years of age. They were randomly assigned to either an alcohol or a placebo group. Aggression was measured using a modified version of the Taylor Aggression Paradigm in which electric shocks are received from, and delivered to, a same gender fictitious opponent during a supposed competitive interpersonal task. Aggression was operationalized as the intensity and duration of shocks that participants administered to their "opponent." Overall, men were more aggressive than women. Alcohol increased aggression for both men and women but this effect was stronger for men. This is one of the first laboratory studies to demonstrate that alcohol increases aggression in women.

  5. "Macho men" and preventive health care: implications for older men in different social classes.

    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.

    BACKGROUND Serum testosterone concentrations decrease as men age, but benefits of raising testosterone levels in older men have not been established. METHODS We assigned 790 men 65 years of age or older with a serum testosterone concentration of less than 275 ng per deciliter and symptoms suggesting hypoandrogenism to receive either testosterone gel or placebo gel for 1 year. Each man participated in one or more of three trials — the Sexual Function Trial, the Physical Function Trial, and the Vitality Trial. The primary outcome of each of the individual trials was also evaluated in all participants. RESULTS Testosterone treatment increased serum testosterone levels to the mid-normal range for men 19 to 40 years of age. The increase in testosterone levels was associated with significantly increased sexual activity, as assessed by the Psychosexual Daily Questionnaire (P<0.001), as well as significantly increased sexual desire and erectile function. The percentage of men who had an increase of at least 50 m in the 6-minute walking distance did not differ significantly between the two study groups in the Physical Function Trial but did differ significantly when men in all three trials were included (20.5% of men who received testosterone vs. 12.6% of men who received placebo, P=0.003). Testosterone had no significant benefit with respect to vitality, as assessed by the Functional Assessment of Chronic Illness Therapy–Fatigue scale, but men who received testosterone reported slightly better mood and lower severity of depressive symptoms than those who received placebo. The rates of adverse events were similar in the two groups. CONCLUSIONS In symptomatic men 65 years of age or older, raising testosterone concentrations for 1 year from moderately low to the mid-normal range for men 19 to 40 years of age had a moderate benefit with respect to sexual function and some benefit with respect to mood and depressive symptoms but no benefit with respect to vitality or

    Limited prevalence data for HIV, hepatitis B surface antigen (HBsAg), and hepatitis C virus (HCV) exist for Afghanistan. We studied a cross-sectional sample of adult injection drug users (IDUs) in Kabul, Afghanistan, from June 2005 through June 2006. Study participants completed interviewer-administered questionnaires and underwent testing for HIV, antibody to HCV, and HBsAg. Overall prevalences of HIV, HCV, and HBsAg were 3.0% (95% confidence interval [CI] 1.7%–5.1%), 36.6% (95% CI 32.2%–41.0%), and 6.5% (95% CI 4.2%–8.7%), respectively (N = 464). Among male IDUs (n = 463), risky behavior, including sharing syringes (50.4%), paying women for sex (76.2%), and having sex with men or boys (28.3%), were common. Needle sharing, injecting for >3 years, and receiving injections from nonmedical providers were independently associated with increased risk for HCV infection. The high prevalence of risky behavior indicate that Kabul is at risk for an HIV epidemic. Scale-up of harm-reducing interventions is urgently needed. PMID:18252103

    Thorburn, Sheryl; Szalacha, Laura A.

    2017-01-01

    The Hmong in the U.S. who emigrated from Southeast Asia, an area where hepatitis B is endemic, experience high rates of hepatitis B infection and liver cancer compared to non-Hispanic whites. This exploratory study examined the Hmong’s perceptions of risk of hepatitis B infection. We interviewed 83 Hmong women and men living in Oregon. In bivariate statistical analysis, greater perceived susceptibility, lower perceived barriers, and having a healthcare provider recommendation were each significantly related to having ever been screened for hepatitis B. Logistic regression models indicated that having a recommendation by a doctor or healthcare provider was the strongest predictor of having been screened for hepatitis B, followed by education and insurance. Future interventions with the Hmong population should focus on the important role of health care providers play in raising awareness about hepatitis B infection and increasing screening uptake.

  14. Mens' attitudes about abortion in Uganda.

    PubMed

    Moore, Ann M; Jagwe-Wadda, Gabriel; Bankole, Akinrinola

    2011-01-01

    Abortion is illegal in Uganda except to save the life of the woman. Nevertheless, the practice is quite common: about 300,000 induced abortions occur annually among Ugandan women aged 15-49 (Singh et al., 2005) and a large proportion of these women require treatment for post-abortion complications. In the male-dominant culture of Uganda, where men control most of the financial resources, men play a critical part in determining whether women receive a safe abortion, or appropriate treatment if they experience abortion complications. This study examines men's roles in determining women's access to a safer abortion and post-abortion care. It draws on in-depth interviews carried out in 2003 with 61 women aged 18-60 and 21 men aged 20-50 from Kampala and Mbarara, Uganda. Respondents' descriptions of men's involvement in women's abortion care agreed that men's stated attitudes about abortion often prevented women from involving them in either the abortion or post-abortion care. Most men believe that if a woman is having an abortion, it must be because she is pregnant with another man's child, although this does not correspond with women's reasons for having an abortion--a critical disjuncture revealed by the data between men's perceptions of, and women's realities regarding, reasons for seeking an abortion. If the woman does experience post-abortion complications, the prevailing attitude among men in the sample was that they cannot support a woman in such a situation seeking care because if it had been his child, she would not have had a covert abortion. Since money is critical to accessing appropriate care, without men's support, women seeking an abortion may not be able to access safer abortion options and if they experience complications, they may delay care-seeking or may not obtain care at all. Barriers to involving men in abortion decision-making endanger women's health and possibly their lives.

    The objective was to learn about the hepatitis prevention behavior of relatively unacculturated North American Chinese adults, along with their knowledge, beliefs, and perceptions with regard to hepatitis, screening, and vaccination. Forty Chinese men and women, aged 18-64, were recruited from immigrant communities in Seattle, Washington, and Vancouver, British Columbia. Semi-structured interviews (Cantonese or Mandarin) were audiotaped, translated, transcribed verbatim, and coded. Open coding, axial coding, constant comparison methods, and QSR NUD*IST 5 software was used for analysis. Findings were validated using eight focus groups. Findings indicated that many interviewees lack accurate knowledge with regard to hepatitis, often confusing the different types. Perceived causes of hepatitis included potentially harmful food (e.g., fried foods or potentially contaminated foods), alcohol, contact with infected individuals, stress, and inadequate rest. Preventive strategies associated with Chinese health beliefs included the use of Chinese herbal medicine, maintaining a stress-free mind, strengthening the body's natural defenses, and getting enough sleep. Other preventive strategies were the practice of good hygiene, vaccination, and the avoidance of contact with infected persons. Vaccination was not seen as primary, as 65% of those who had heard of hepatitis vaccination did not cite it as a means for hepatitis prevention until asked. Also, participants lacked information about the types and purposes of hepatitis vaccination and were worried about side effects. In conclusion, any attempt to promote hepatitis testing and vaccination among the North American Chinese should take traditional beliefs and practices into consideration.

    2015-09-08

    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.

    The burden of viral hepatitis in India is not well characterized. In 2009, the national Integrated Disease Surveillance Programme (IDSP) began conducting surveillance across all Indian states for epidemic-prone diseases, including foodborne and waterborne forms of viral hepatitis (e.g., hepatitis A and E). Information on outbreaks of all forms of viral hepatitis, including A, B, C, and E, also is collected. This report summarizes viral hepatitis surveillance and outbreak data reported to IDSP during 2011-2013. During this period, 804,782 hepatitis cases and 291 outbreaks were reported; the virus type was unspecified in 92% of cases. Among 599,605 cases tested for hepatitis A, 44,663 (7.4%) were positive, and among 187,040 tested for hepatitis E, 19,508 (10.4%) were positive. At least one hepatitis outbreak report was received from 23 (66%) of 35 Indian states. Two-thirds of outbreaks were reported from rural areas. Among 163 (56%) outbreaks with known etiology, 78 (48%) were caused by hepatitis E, 54 (33%) by hepatitis A, 19 (12%) by both hepatitis A and E, and 12 (7%) by hepatitis B or hepatitis C. Contaminated drinking water was the source of most outbreaks. Improvements in water quality and sanitation as well as inclusion of hepatitis A vaccine in childhood immunization programs should be considered to reduce the public health burden of hepatitis in India. Efforts to decrease the proportion of cases for which the etiology is unspecified, including expanding the IDSP to support hepatitis B and C testing, might help further elucidate the epidemiology of these diseases.

    Occult hepatitis B virus (HBV) infection (OBI) refers to the presence of HBV DNA in the absence of detectable hepatitis B surface antigen. Since OBI was first described in the late 1970s, there has been increasing interest in this topic. The prevalence of OBI varies according to the different endemicity of HBV infection, cohort characteristics, and sensitivity and specificity of the methods used for detection. Although the exact mechanism of OBI has not been proved, intra-hepatic persistence of viral covalently closed circular DNA under the host’s strong immune suppression of HBV replication and gene expression seems to be a cause. OBI has important clinical significance in several conditions. First, OBI can be transmitted through transfusion, organ transplantation including orthotopic liver transplantation, or hemodialysis. Donor screening before blood transfusion, prophylaxis for high-risk organ transplantation recipients, and dialysis-specific infection-control programs should be considered to reduce the risk of transmission. Second, OBI may reactivate and cause acute hepatitis in immunocompromised patients or those receiving chemotherapy. Close HBV DNA monitoring and timely antiviral treatment can prevent HBV reactivation and consequent clinical deterioration. Third, OBI may contribute to the progression of hepatic fibrosis in patients with chronic liver disease including hepatitis C. Finally, OBI seems to be a risk factor for hepatocellular carcinoma by its direct proto-oncogenic effect and by indirectly causing persistent hepatic inflammation and fibrosis. However, this needs further investigation. We review published reports in the literature to gain an overview of the status of OBI and emphasize the clinical importance of OBI. PMID:25544873

    In order to enhance screening and preventive strategies, this study investigated the seroprevalence of hepatitis A, B, and C in the general adult urban population and in subgroups. In 2004, sera from 1,364 adult residents of Amsterdam were tested for viral markers. Sociodemographic characteristics were collected using a standardized questionnaire. For hepatitis A, 57.0% was immune. Of first-generation immigrants from Turkey and Morocco, 100% was immune. Of all Western persons and second-generation non-Western immigrants, approximately half was still susceptible. For hepatitis B, 9.9% had antibodies to hepatitis B core antigen (anti-HBc) and 0.4% had hepatitis B surface antigen. Anti-HBc seroprevalences were highest among first-generation immigrants from Surinam, Morocco, and Turkey, and correlated with age at the time of immigration, and among men with a sexual preference for men. Seroprevalence among second-generation immigrants was comparable to Western persons. The seroprevalence of hepatitis C virus antibodies was 0.6%. In conclusion, a country with overall low endemicity for viral hepatitis can show higher endemicity in urban regions, indicating the need for differentiated regional studies and prevention strategies. More prevention efforts in cities like Amsterdam are warranted, particularly for hepatitis A and B among second-generation immigrants, for hepatitis B among men with a sexual preference for men, and for hepatitis C. Active case finding strategies are needed for both hepatitis B and C.

    There isn't a practice in the United States that doesn't have a concern about accounts receivable. The financial success of any practice depends on the care and feeding of the accounts receivable. This is not an area of practice management that can be taken lightly or delegated to someone who is not attentive to detail and doggedly persistent. In this article, we will discuss how to identify problematic accounts receivable and what can be done to bring the accounts receivable under control. We will provide you with a plan of action that can be adopted by any practice regardless of size, number of physicians, or whether the practice uses in-house billing or outsources its billing arrangements.

    The effect of Microcurrent Electrical Nerve Stimulation (MENS) was evaluated and compared with occlusal splint therapy in temporomandibular disorders (TMD) patients with muscle pain. Twenty TMD patients were divided into four groups. One received occlusal splint therapy and MENS (I); other received splints and placebo MENS (II); the third, only MENS (III) and the last group, placebo MENS (IV). Sensitivity derived from muscle palpation was evaluated using a visual analogue scale. Results were submitted to analysis of variance (p<0.05). There was reduction of pain level in all groups: group I (occlusal splint and MENS) had a 47.7% reduction rate; group II (occlusal splint and placebo MENS), 66.7%; group III (MENS), 49.7% and group IV (placebo MENS), 16.5%. In spite of that, there was no statistical difference (analysis of variance / p<0.05) between MENS and occlusal splint therapy regarding muscle pain reduction in TMD patients after four weeks.

    If equal employment opportunities were a reality, one would expect all salaries to be more or less randomly distributed between the genders. The data does not show random distribution. Of the awards studied in depth, 11 of the 18 showed a statistically significant different salary between women and men. Two awards had a marginal probability of significance, and five had a probability of significance of less than five per cent. The data shows clearly the need for EEO initiatives for women within the health service and identifies the areas of greatest concern. The many questions raised through this general analysis of the data will guide further research and the development of an EEO management plan that is specific to the needs of the Palmerston North Area Health Board. Also highlighted is the need for similar statistics showing the composition of the workforce by ethnicity and disability. Only when this has been obtained and analysed can specifically targeted EEO programmes be developed to meet the workforce needs of the Board.

    While recently there have been renewed interest in women's childbearing intentions, the authors sought to bring needed research attention to understanding men's childbearing intentions. Nationally representative data from the 2006-2010 National Survey of Family Growth (NSFG) was used to examine pregnancy intentions and happiness for all births reported by men in the 5 years preceding the interview. We used bivariate statistical tests of associations between intention status, happiness about the pregnancy, and fathers' demographic characteristics, including joint race/ethnicity and union status subgroups. Multivariate logistic regressions were used to calculate adjusted odds ratios of a birth being intended, estimated separately by father's union status at birth. Using comparable data and measures from the male and female NSFG surveys, we tested for gender differences intentions and happiness, and examined the sensitivity of our results to potential underreporting of births by men. Nearly four out of ten of births to men were reported as unintended, with significant variation by men's demographic traits. Non-marital childbearing was more likely to be intended among Hispanic and black men. Sixty-two percent of births received a 10 on the happiness scale. Happiness about the pregnancy varied significantly by intention status. Men were significantly happier than women about the pregnancies, with no significant difference in intention status. Potential underreporting of births by men had little impact on these patterns. This study brings needed focus to men's childbearing intentions and improves our understanding of the context of their role as fathers. Men need to be included in strategies to prevent unintended pregnancy.

    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

  16. Men's sex-dominance inhibition: do men automatically refrain from sexually dominant behavior?

    PubMed

    2007-12-01

    Men receive conflicting messages about their sexual roles in heterosexual relationships. Men are socialized to initiate and direct sexual activities with women; yet societal norms also proscribe the sexual domination and coercion of women. The authors test these competing hypotheses by assessing whether men inhibit the link between sex and dominance. In Studies 1a and b, using a subliminal priming procedure embedded in a lexical decision task, the authors demonstrate that men automatically suppress the concept of dominance following exposure to subliminal sex primes relative to neutral primes. In Studies 2 and 3, the authors show that men who are less likely to perceive sexual assertiveness as necessary, to refrain from dominant sexual behavior, and who do not invest in masculine gender ideals are more likely to inhibit dominant thoughts following sex primes. Implications for theories of automatic cognitive networks and gender-based sexual roles are discussed.

    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.

    Although the introduction of hepatitis B vaccine has been contributing to the reduction in the prevalence of hepatitis B virus (HBV) carriers worldwide, the treatment of children with chronic HBV infection is a challenge to be addressed. HBeAg seroconversion, which induces low replication of HBV, is widely accepted as the first goal of antiviral treatment in children with chronic hepatitis B. However, spontaneous HBeAg seroconversion is highly expected in children with chronic HBV infection. Therefore, the identification of children who need antiviral treatment to induce HBeAg seroconversion is essential in the management of chronic HBV infection. Guidelines and experts’ opinion show how to identify children who should be treated and how to treat them. If decompensated cirrhosis is absent, interferon-alpha is the first-line antiviral treatment. Nucleos(t)ide analogues (NAs), such as lamivudine, adefovir, entecavir and tenofovir, are also available for the treatment of children, although the approval age differs among them. If decompensated cirrhosis is present, NAs are the first-line antivirals. When the emergence of drug-resistant HBV variants is taken into consideration, entecavir (approved for age 2 years or older) and tenofovir (age 12 years or older), which have high genetic barriers, will play a central role in the treatment of HBV infection. However, the optimal duration of NA treatment and adverse events of long-term NA treatment remain unclear in children. In resource-constrained countries and regions, the financial burden of visiting hospitals, receiving routine blood examination and purchasing antiviral drugs is heavy. Moreover, there is no clear evidence that the induction of HBeAg seroconversion by antiviral treatment prevents the progression of liver disease to cirrhosis and hepatocellular carcinoma in children with chronic HBV infection. It is thus imperative to clarify the clinical impact of antiviral treatment in children with HBV infection. PMID

  4. Integration of hepatitis B vaccination into national immunisation programmes. Viral Hepatitis Prevention Board.

    1997-01-01

    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.

    Aplastic anaemia can coincide with non-A-E hepatitis. Treatment follows a standardised study protocol of the German Society of Paediatric Oncology and Haematology (GPOH). Patients receive immunosuppression and/or bone marrow transplantation. We present six cases of aplastic anaemia after non-A-E hepatitis with different courses. In four of these children illness first presented with acute gastroenteritis. Five out of six children fully recovered, two of these with immunosuppression alone, three after bone marrow transplantation. One patient died due to complications of the bone marrow transplantation. In two patients steroid therapy was carried out to treat the hepatitis. This did not have any effect on the course of their aplastic anemia. We emphasise this common combination of aplastic anemia following non-A-E hepatitis. This overview underlines the necessity of regular blood testing after non-A-E hepatitis. Often gastroenteritis seems to precede illness thus perhaps indicating an infectious trigger.

    Five livers of equine fetuses, aborted due to the action of equine abortion virus, five livers from men, two of whom died of epidemic hepatitis and three obtained by needle biopsies, 5 livers of dogs with infectious canine hepatitis and 7 livers of ducklings that had hepatitis, were studied histopathologically. The foals' livers were studied by several staining methods and the others by H. E. only. The results indicate that the lesions are quite similar in the four species with the appearance of nuclear inclusion bodies only in foals and dogs. The strong staining properties of the nuclear inclusion bodies in infectious canine hepatitis and the weak staining properties of the equine virus abortion reveal that the protein-DNA association is different resulting in a different electropolarity. The lesions in foals are of two main types, one a Necrotic-Mosaic Type in which the hepatocyte degeneration is irregularly distributed within the hepatic lobules and the other an Hyperplastic Type in which marked regeneration occurs. In the Hyperplastic Type the practical absence of plasmocytes in foals' livers might suggest that if the newborn is a female, abortions may occur later in life because the virus remained alive in colts which were born in an immune tolerance state. Histologically the picture in the livers of aborted foals assume features of a viral hepatitis similar to the viral hepatitis in men, dogs and ducklings.

    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.

    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".

    Careful evaluation was carried out in 93 men older than 50 with erectile dysfunction. Their mean age was 61 years and the disorder had been present for a mean of 4.5 years. While 14 men (15%) had psychosocial factors that may have been pertinent, only 2 scored poorly on an Affect Balance Scale and 3 were receiving psychoactive medications. Results of nocturnal penile tumescence were abnormal in 91%. In 39% penile-brachial pressure indices were suggestive of pelvic vascular disease and in 9% were consistent with a pelvic “steal syndrome.” Pelvic or peripheral nerve conduction disorders were also commonly seen in 54%. Endocrinopathy may have contributed to the dysfunction in 35%. Twenty-one men had diabetes mellitus, two new cases of hypothyroidism were discovered and hypogonadism was diagnosed definitely in four and considered likely in five others. Coexisting medical conditions were found in more than 90% of the men, especially hypertension, use of antihypertensive medications and atherosclerotic disease. Previous prostatectomies (19%) and vasectomies (30%) were common in the surgical histories. Given the wide range of disorders uncovered in older men complaining of impotence, diagnostic study of potential causes may lead to a more rational approach for the evaluation and management of these men.

    We evaluated prevalence of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) among prison inmates in France in 2010, in a cross-sectional single-day study based on a two-stage design. Sampling favoured larger establishments and included all types of prisons. Establishments were stratified by geographical region. Estimates were adjusted by post-stratification of the total population of inmates in France. From 60,975 inmates in all 188 prisons on the sampling day, 2,154 were selected from 27 prisons, and 1,876 questionnaires completed. HIV prevalence was estimated at 2.0% (95% confidence interval (CI): 0.9–4.2), 2.6% (95% CI: 0.7–8.8) in women and 2.0% (95% CI: 0.9–4.3) in men; 75% of inmates were receiving treatment for HIV. HCV prevalence was estimated at 4.8% (95% CI: 3.5–6.5) and was higher for women (11.8%; 95% CI: 8.5–16.1) than men (4.5%; 95% CI: 3.3–6.3). Almost half of HCV-infected inmates had chronic hepatitis C and 44% were receiving or had received treatment. HIV and HCV prevalence was six times higher than in the general population, and 2.5% of inmates had viraemic hepatitis C. The moment of incarceration provides an ideal opportunity for testing and treating, limiting spread of HCV and improving patients' prognosis.

    Background/Aim We assessed the effects of long-term peginterferon therapy and disease progression on health-related quality of life (HRQOL), symptoms, and sexual health in patients with chronic hepatitis C (CHC) and advanced fibrosis or cirrhosis. Methods 517 HALT-C Trial patients received peginterferon alfa-2a (90 μg/week); 532 received no additional treatment for 3.5 years. Patients were followed for outcomes of death, hepatocellular carcinoma and hepatic decompensation. Sexual health, SF-36 scores, and symptoms were serially assessed by repeated measures analyses of covariance. Results Patients with cirrhosis (n=427) reported lower general well-being and more fatigue (p<0.001) than patients with fibrosis (n=622). Physical scores declined significantly over time, independent of treatment, and patients with cirrhosis reported lower scores. Vitality scores were lower in those with cirrhosis, and treated patients experienced a greater decline over time than untreated patients; HRQOL rebounded after treatment ended. Patients with a clinical outcome had significantly greater declines in all SF-36 and symptom scores. Among men, sexual health scores were significantly worse in treated patients and in those with a clinical outcome. Conclusions Clinical progression of CHC and maintenance peginterferon therapy led to worsening of symptoms, HRQOL, and, in men, sexual health in a large patient cohort followed over 4 years.

    This study examined the impact of an ultraviolet (UV) photography intervention and masculinity on college men's sun protection cognitions, including: perceived vulnerability to skin damage, attitudes toward sun protection, willingness to engage in sun protection behaviors, and intentions to receive a skin cancer exam. After completing a baseline survey, participants (N = 152) viewed a black-and-white photo of their face. Half also viewed a photo showing their UV damage. Participants then completed a second survey assessing sun protection cognitions. Regressions revealed that masculinity predicted lower sun protection cognitions, and men in the UV photograph condition reported higher sun protection cognitions. Masculinity by condition interactions showed that the positive effect of UV photography was stronger among masculine men. Negative associations between masculinity and sun protection cognitions were significant only among men who did not receive the intervention. Findings suggest that UV photography is a promising sun protection intervention among masculine men.

    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

  1. For men only.

    PubMed

    1993-01-01

    In 1985 the Colombian Family Planning Association PROFAMILIA realized that men did not want to come to its family planning centers simply because they felt intimidated by the feminine atmosphere there. Nor did they dare disclose their problems and sexual questions even to a female professional. The solution was to establish a family planning center, La Clinica del Hombre (Men's Clinic), providing services exclusively for men and staffed with men to provide the necessary privacy. Latin American men's attitudes are changing. In 1985 in Bogota, the majority of men were convinced that a vasectomy was equivalent to castration. In 1993, 300 vasectomies were performed in the clinic each month. The Colombian Family Planning Association is not only providing contraception, but also information on sexual and reproductive education to avoid misunderstanding of the available methods. PROFAMILIA has incorporated a sexuality consultation into its services, so they can deal with husbands and wives separately, without spoiling the couple's relationship. PROFAMILIA now has 7 family planning clinics for men and 48 for women, thanks to the contribution of international donors. The Challenge Grant for Men's Programs, given by an anonymous donor from the United States, helped with the fund-raising to open 3 clinics in the Atlantic Coast Region where needs were vital. The Clinica del Hombre will incorporate a program to treat infertility, in addition to the department of urology, general medicine, ambulatory surgery, and treatment of sexually transmitted diseases. In January, 1994, they will begin offering dental and plastic surgery services because, owing to the violence that exists in the country, there are many men whose faces are disfigured and who need to have corrective plastic surgery.

  2. Eltrombopag in chronic hepatitis C

    Chronic hepatitis C is a public health problem worldwide. Unfortunately, not all patients may benefit from antiviral therapy due to thrombocytopenia. Its causes are represented by portal hypertension and platelet sequestration in the spleen, decreased serum levels or activity of thrombopoietin, the bone marrow suppression induced by hepatitis C virus and a possible adverse effect of interferon. Thrombopoietin receptor analogs may contribute to increase platelet counts in these patients. Eltrombopag binds to another region of the thrombopoietin receptor compared to endogenous thrombopoietin and stimulates the proliferation and maturation of megakaryocytes and the platelet production in a dose-dependent manner. Eltrombopag has proven its effectiveness for the treatment of patients with primary immune thrombocytopenia. Its indication for other hemopathies or situations (like thrombocytopenia secondary to chemo- or radiotherapy, acute leukemia, myelodysplastic syndroms, acquired and hereditary bone marrow failure, and platelet donors) is under study. Eltrombopag may be particularly useful in patients with advanced chronic hepatitis or liver cirrhosis who require antiviral treatment. We present a minireview on the results of treatment with eltrombopag in patients chronically infected with hepatitis C virus, highlighting the benefits and mentioning possible adverse effects. In some studies eltrombopag increased the number of virological responses after clasical antiviral treatment of patients with chronic hepatitis C and reduced the transfusional requirements of those who had to be subjected to invasive surgery. Eltrombopag is a solution for many of these patients, which allows them receiving antiviral therapy and sometimes getting a sustained virological response, but they must be well monitored to prevent possible thromboembolic or bone marrow complications or liver failure occurrence.

    Advantages and constraints of remote measurements using heterodyne spectroscopy near 30 microns are discussed. The state of the art of wideband HgCdTe photomixers and PbSnSe diode-laser local oscillators being developed for FIR heterodyne receivers is described. The first compact 30-micron heterodyne radiometer was built, and initial results at 28-microns show about 2-percent mixer efficiency for a 500-MHz-bandwidth receiver. Factors limiting receiver performance are discussed, along with the projected sensitivity of new interdigitated-electrode HgCdTe photoconductor mixers being developed for operation up to 200 microns.

    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.

  2. 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.

It is recommended that careful attention be given to the overall thermal systems design, especially to conductive losses about the window and areas of relatively thin insulation. If the cavity design is carefully managed to insure a small, minimally reradiating aperture, the goal of a very high efficiency cavity receiver is a realistic one.

    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 C virus (HCV) is a leading cause of end-stage liver disease worldwide and the most common indication for liver transplantation in the United States and Europe. HCV nearly always recurs in liver-transplanted patients, and 10 to 25% of them develop cirrhosis within 5 to 10 years. One of the strategies suggested to limit virological HCV recurrence is pretransplant antiviral treatment, but studies are warranted on the pharmacokinetics of antiviral drugs in cirrhotic patients, the benefits of fixed or escalating antiviral drug dosage schedules, the duration of the treatment, and the indications for using growth factors. Several risk factors are associated with a more aggressive recurrent HCV and early allograft failure, such as an older donor age. The relationship between immunosuppression and fibrosis progression in HCV recurrence remains uncertain. Concerning the antiviral treatment, treating established recurrent disease with a combination of interferon and ribavirin has been the mainstay of management to date, but when it is best to start and how to manage the side effects are still controversial issues. Antiviral treatment should be started once the disease has been confirmed by a biopsy when the fibrosis develops, providing that ongoing acute or chronic rejection, biliary obstruction, vascular damage, autoimmune diseases and sepsis, and any other standard contraindications for antiviral therapy, have been excluded. HCV recurrence after liver transplantation may well lead to graft failure and become an indication for retransplantation, but this is done in a relatively small number of cases, accounting for only 3 to 5% of retransplanted patients, since retransplantation is associated with much worse results than primary liver transplant procedures. We must be prepared for the fact that increasing numbers of HCV-positive recipients with allografts failing due to recurrent HCV will be asking to be retransplanted-and we do not know yet how to respond to this

    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.

    Understanding the country-specific epidemiology of disease, which may vary greatly among countries, is crucial for identifying the most appropriate preventive and control measures. An overview of the local epidemiology of viral hepatitis in Croatia is given in this paper. The overall prevalence of hepatitis B in Croatia is low (less than 2% HBsAg carriers in the general population). Hepatitis B incidence and prevalence began to decline significantly following the introduction of universal hepatitis B vaccination in 1999. Information on HBsAg seroprevalence is derived from routine testing of certain subpopulations (pregnant women, blood donors) and seroprevalence studies mostly targeted at high-risk populations. Universal childhood vaccination against hepatitis B remains the main preventive measure. We recommend testing for immunity one to two months after the third dose of hepatitis B vaccine for health-care workers. The incidence and prevalence of hepatitis C have also been declining in the general population. The main preventive measures are ensuring safety of blood products, prevention of drug abuse, and harm reduction programs for intravenous drug users. Hepatitis A incidence has declined dramatically since fifty years ago, when thousands of cases were reported annually. In the last five years, an average of twenty cases have been reported per year. The reduction of hepatitis A is a consequence of improved personal and community hygiene and sanitation. Hepatitis D has not been reported in Croatia. The risk of hepatitis D will get to be even smaller as the proportion of population vaccinated against hepatitis B builds up. Hepatitis E is reported only sporadically in Croatia, mostly in persons occupationally in contact with pigs and in travelers to endemic countries. In conclusion, Croatia is a low prevalence country for hepatitides A, B and C. Hepatitis D has not been reported to occur in Croatia and there are only sporadic cases of hepatitis E. Since hepatitis

    Hepatitis A (HA) has been a vaccine-preventable disease since 1995. In Catalonia, a universal combined hepatitis A+B vaccination program of preadolescents was initiated at the end of 1998. However, outbreaks are reported each year and post-exposure prophylaxis (PEP) with hepatitis A virus (HAV) vaccine or immunoglobulin (IG) is recommended to avoid cases. The aim of this study was to assess the effectiveness of HAV vaccine and IG in preventing hepatitis A cases in susceptible exposed people. A retrospective cohort study of contacts of HA cases involved in outbreaks reported in Catalonia between January 2006 and December 2012 was made. The rate ratios and 95% confidence intervals (CI) of HA in susceptible contacts receiving HAV or IG versus those without PEP were calculated. There were 3550 exposed persons in the outbreaks studied: 2381 received one dose of HAV vaccine (Hepatitis A or hepatitis A+B), 190 received IG, and 611 received no PEP. 368 exposed subjects received one dose of HAV vaccine and IG simultaneously and were excluded from the study. The effectiveness of PEP was 97.6% (95% CI 96.2-98.6) for HAV vaccine and 98.3% (95% CI 91.3-99.9) for IG; the differences were not statistically significant (p = 0.36). The elevated effectiveness of HAV vaccination for PEP in HA outbreaks, similar to that of IG, and the long-term protection of active immunization, supports the preferential use of vaccination to avoid secondary cases.

    Objectives: To establish natural seroconversion rates and incidence of hepatic pathology in perinatally infected hepatitis B carriers. Methods: Seventy three perinatally infected hepatitis B carriers identified through maternal screening were evaluated. Fifty three were born to parents from the Indian subcontinent, nine were Oriental, six were Afro-Caribbean, and five were white. Median follow up was 10.24 (range 2.02–20.16) years. Results: Only three of the children followed up had cleared hepatitis B surface antigen during this period, and 30% of the children had seroconverted to anti-HBe. Seroconversions to anti-HBe were observed in Asian (18/50) and white (4/5) children, but not in Oriental or Afro-Caribbean children. More girls (40%) than boys (23%) had seroconverted, but the difference was not significant. All children were asymptomatic with normal physical examination, growth, and development. Almost half (48%) of the hepatitis B e antigen (HBeAg) positive children had normal hepatic transaminases and liver function. Thirty five liver biopsies were performed in children with active virus replication (HBeAg or hepatitis B virus DNA positive) who were being considered for antiviral treatment as part of a clinical trial and were scored using the Ishak method. Two thirds (62%) of the children had mild hepatitis, 60% had mild fibrosis, and 18% had moderate to severe fibrosis. There was a weak correlation between histological evidence of hepatitis and hepatic transaminase activity, implying that biochemical monitoring of hepatic disease activity may be ineffective. Conclusions: These asymptomatic hepatitis B virus carrier children remain infectious in the medium to long term with notable liver pathology. They should receive antiviral treatment to reduce infectivity and to prevent further progression of liver disease. Hepatic transaminases alone are not a reliable marker of liver pathology, and liver histology is essential before consideration for antiviral

    Abstract To evaluate quantitative hepatitis B surface antigen (qHBsAg) as a diagnostic marker for inactive carriers (ICs) and hepatitis B surface antigen (HBsAg) seroclearance in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) patients. We retrospectively studied 300 HBeAg-negative CHB patients with initial serum hepatitis B virus (HBV) Deoxyribonucleic acid (DNA) levels <2000 IU/mL. Serum HBV DNA and alanine aminotransferase (ALT) levels were monitored every 6 months for 24 months. ICs were identified as having persistent HBV DNA levels <2000 IU/mL and normal ALT levels, whereas active carriers (ACs) were identified as having HBV DNA levels ≥2000 IU/mL, with or without elevated ALT levels. The serum qHBsAg level was defined at baseline and evaluated as a diagnostic predictor using a receiver-operating characteristic curve. The study group comprised 134 men and 166 women with a median age of 41.5 years. At baseline, 200 ICs displayed lower levels of qHBsAg (1492 IU/mL) compared with 100 ACs (2936 IU/mL) (P = 0.005). The qHBsAg level was independently associated with the IC state and HBsAg seroclearance. Baseline qHBsAg levels <1000 IU/mL and HBV DNA levels <2000 IU/mL, when detected simultaneously, allowed for identification of ICs with 41% sensitivity and 72% specificity. Fifteen patients (5%) displayed HBsAg seroclearance after 24 months. A qHBsAg cutoff value of <50 IU/mL provided 100% sensitivity and 92% specificity in predicting HBsAg seroclearance. The qHBsAg level at a single timepoint among HBeAg-negative CHB patients with low HBV DNA levels at baseline was not a predictive marker for ICs; however, it accurately predicted spontaneous HBsAg seroclearance at 24 months.

    Despite the increasing prevalence of nonalcoholic fatty liver disease (NAFLD), its pathogenesis and clinical significance remain poorly defined. In this study, we examined and compared the distribution of hepatic triglyceride content (HTGC) in 2,287 subjects from a multiethnic, population-based sample (32.1% white, 48.3% black, and 17.5% Hispanic) using proton magnetic resonance spectroscopy. HTGC varied over a wide range (0.0%-41.7%; median, 3.6%) in the population. Almost one third of the population had hepatic steatosis, and most subjects with hepatic steatosis had normal levels of serum alanine aminotransferase (79%). The frequency of hepatic steatosis varied significantly with ethnicity (45% in Hispanics; 33% in whites; 24% in blacks) and sex (42% in white men; 24% in white women). The higher prevalence of hepatic steatosis in Hispanics was due to the higher prevalence of obesity and insulin resistance in this ethnic group. However, the lower frequency of hepatic steatosis in blacks was not explained by ethnic differences in body mass index, insulin resistance, ethanol ingestion, or medication use. The prevalence of hepatic steatosis was greater in men than women among whites, but not in blacks or Hispanics. The ethnic differences in the frequency of hepatic steatosis in this study mirror those observed previously for NAFLD-related cirrhosis (Hispanics > whites > blacks). In conclusion, the significant ethnic and sex differences in the prevalence of hepatic steatosis documented in this study may have a profound impact on susceptibility to steatosis-related liver disease.

    Objective Insulin is often infused based upon total body weight (TBW) or fat free mass (FFM)for glucose clamp protocols. We observed greater insulin concentrations in men than women using this approach and examined whether splanchnic insulin extraction accounts for the differences. Materials/Methods Whole body insulin clearance was measured during a pancreatic clamp study (somatostatin to inhibit islet hormone secretion) including 13 adults (6 men) and whole body insulin clearance was measured during a euglycemic, hyperinsulinemic clamp study including 27 adults (13 men). Femoral artery and hepatic vein blood samples were collected to measure splanchnic insulin balance. For the pancreatic clamp study insulin was infused at rates of 0.5, 1.0, and 2.0 mU•kgTBW−1•min−1 and for the euglycemic, hyperinsulinemic clamp study insulin was infused at 2.5 mU•kg FFM−1•min−1. Results Significantly greater arterial insulin concentrations were found in men than women. Splanchnic plasma flow was similar in men and women in both protocols. Splanchnic insulin extraction and the fraction of infused insulin removed by splanchnic bed were significantly greater in men than in women. However, whole body insulin clearance was greater in women than men. Conclusions Infusing insulin per body weight or FFM results in higher plasma insulin concentrations in men than women. Splanchnic insulin extraction is greater in men, indicating greater peripheral insulin clearance in women accounts for the sex differences we observed. This finding has implications for insulin clamp study design and raises the question of which tissues take up more insulin in women. PMID:22000585

    Anderson, Anna J.; Andrew, Ruth; Homer, Natalie Z.; Jones, Gregory C.; Smith, Kenneth; Livingstone, Dawn E.; Walker, Brian R.

    2016-01-01

    Context: The mechanism of action of metformin remains unclear. Given the regulation of the cortisol-regenerating enzyme 11βhydroxysteroid dehydrogenase 1 (11βHSD1) by insulin and the limited efficacy of selective 11βHSD1 inhibitors to lower blood glucose when co-prescribed with metformin, we hypothesized that metformin reduces 11βHSD1 activity. Objective: To determine whether metformin regulates 11βHSD1 activity in vivo in obese men with and without type 2 diabetes mellitus. Design: Double-blind, randomized, placebo-controlled, crossover study. Setting: A hospital clinical research facility. Participants: Eight obese nondiabetic (OND) men and eight obese men with type 2 diabetes (ODM). Intervention: Participants received 28 days of metformin (1 g twice daily), placebo, or (in the ODM group) gliclazide (80 mg twice daily) in random order. A deuterated cortisol infusion at the end of each phase measured cortisol regeneration by 11βHSD1. Oral cortisone was given to measure hepatic 11βHSD1 activity in the ODM group. The effect of metformin on 11βHSD1 was also assessed in human hepatocytes and Simpson-Golabi-Behmel syndrome adipocytes. Main Outcome Measures: The effect of metformin on whole-body and hepatic 11βHSD1 activity. Results: Whole-body 11βHSD1 activity was approximately 25% higher in the ODM group than the OND group. Metformin increased whole-body cortisol regeneration by 11βHSD1 in both groups compared with placebo and gliclazide and tended to increase hepatic 11βHSD1 activity. In vitro, metformin did not increase 11βHSD1 activity in hepatocytes or adipocytes. Conclusions: Metformin increases whole-body cortisol generation by 11βHSD1 probably through an indirect mechanism, potentially offsetting other metabolic benefits of metformin. Co-prescription with metformin should provide a greater target for selective 11βHSD1 inhibitors. PMID:27459533

    Sexual dysfunction in general and erectile dysfunction (ED) in particular significantly affect men's quality of life. Some patients who have ED, also develop osteoporosis. So, in this study we investigated the relationship between erectile dysfunction and osteoporosis in men. 95 men with erectile dysfunction and 82 men with normal sexual function were included in the study. The men's sexual functions were evaluated by International Index of Erectile Function-5 items (IIEF-5). All men received a Dual Energy X-ray Absorptiometry (DEXA; Hologic) scan to measure bone mineral density (BMD) for osteoporosis. Chi-square test was used for statistical analysis. Mean age was 53.5 (38-69) in ED group and 50.1 (31-69) in control group. In ED group the men have lower T score levels than those of the control group. In conclusion, the men who have erectile dysfunction were at more risk for osteoporosis. The results of the present study demonstrate that the men with erectile dysfunction have low bone mineral density and they are at higher risk for osteoporosis. Because of easy and noninvasive evaluation of osteoporosis, patients with ED should be checked for bone mineral density and osteoporotic male subjects should be evaluated for ED.

    2015-11-01

    Although numerous randomized studies have shown that testosterone replacement therapy (TRT) improves intermediate outcomes in patients at risk and in those with proven cardiovascular disease (CVD), results derived mainly from registries and observational studies have suggested an increased cardiovascular risk in elderly men receiving often supra-therapeutic doses of testosterone. Recent meta-analyses have shown that when testosterone has been used in patients with pre-existing cardiovascular conditions, the effect on the disease has been either beneficial or neutral. Similar results have been reported in hypo- and eugonadal men. Contrasting results have been reported by two trials of testosterone treatment in frail elderly men. Reports from poorly analyzed databases have reported an increased risk of cardiovascular events with testosterone use. More recently, a population-based study showed no increased cardiovascular risk of testosterone replacement in hypogonadal men. Available data from controlled clinical trials suggest that the use of testosterone in elderly men does not increase cardiovascular risk nor the risk of events. Studies in men with CVD, angina, or heart failure report a benefit from testosterone replacement in men with or without hypogonadism. Therefore, at present, the cardiovascular benefits of TRT in elderly men outweigh the risks. This is particularly evident in those men with pre-existing CVD.

    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.

  11. Contraceptive developments for men.

    PubMed

    Amory, John K

    2007-03-01

    Efforts are underway to develop new methods of contraception for men. The most promising approach to male contraceptive development is hormonal and involves the administration of testosterone. When testosterone is administered to a man, it functions as a contraceptive by suppressing the secretion of luteinizing hormone and follicle-stimulating hormone from the pituitary gland, thereby depriving the testes of the signals required for spermatogenesis. After two to three months of treatment, low levels of gonadotropins lead to markedly decreased sperm counts and effective contraception in a majority of men. In many clinical trials, male hormonal contraception has proven to be free from serious adverse effects and is well-tolerated by men. In addition, sperm parameters uniformly normalize when treatment is discontinued. The main drawback to this approach is the observation that spermatogenesis is not suppressed to zero in all men, meaning that some potential for fertility persists. Because of this, recent studies have combined testosterone with progestogens and/or gonadotropin-releasing antagonists to synergistically suppress pituitary gonadotropins and improve suppression of spermatogenesis. Current combinations of testosterone and progestogens severely suppress spermatogenesis without severe side effects in 80-90% of men, with significant suppression in the remainder of individuals. Recent trials with newer, long-acting forms of injectable testosterone, such as testosterone undecanoate, which can be administered every 8-10 weeks, combined with progestogens, administered either orally or by long-acting implant, have yielded promising results and may soon result in the marketing of a safe, reversible and effective hormonal contraceptive for men.

    2017-03-01

    The epidemiology of hepatitis B in Portugal is insufficiently characterized. We aimed to review the epidemiology of hepatitis B in Portugal since 1980. A literature review was performed in MEDLINE, Scielo, Web of Science, and the Portuguese Scientific Repository for studies containing 'Hepatitis B' and 'Portugal' published from 1980 to June 2016. The initial search was complemented by abstract books from national gastroenterology and hepatology meetings and reports from the Service for Intervention on Addictive Behaviours and Dependences, the Portuguese Blood Institute, and Directorate-General of Health. Further studies were identified in references of retrieved papers and https://www.google.pt. Ninety references were included. Hepatitis B surface antigen (HBsAg) prevalence was up to 2% in the general population and decreased in the last decades: 1.13-2.0% in studies carried out in 1980-1989 and 0.02-1.45% in studies carried out in 1990-2014. Among pregnant women, HBsAg prevalence was 1.35% in those on primary care, but 6.2% among risk parturients. Among drug abusers, HBsAg prevalence decreased from 10-19.6% in the decades of 1980-1990 to 4.8% in 2014. Higher HBsAg prevalence rates were observed among populations of African or Asian origin. Individuals with hepatitis B were mostly men, mean age 36.9-49 years. The most frequent viral genotype was D. Genotype E is more prevalent in patient cohorts from Central-Southern Portugal (10-62%) than those from Northern Portugal (1-4.1%). The proportion of inactive carriers varied from 24.2 to 73%. The prevalence of cirrhosis varied from 5.8 to 23.7%. Portugal is a low-endemicity country for hepatitis B. Nevertheless, prevalence is high among specific subgroups that may benefit from specifically designed healthcare programs.

    This study uses data from the 2009 Behavioral Risk Factors Surveillance System (BRFSS) to examine differences between male and female caregivers by demographics, health-related quality of life (HRQOL), and the effect of social support on HRQOL. Roughly two-thirds of caregivers were women, and demographic characteristics differed among men and women caregivers. Women caregivers reported significantly more mentally and physically unhealthy days than men, but there were no differences between men and women in general health or life satisfaction. Men were significantly more likely to report that they rarely or never received social support. Despite this, the effect of social support on HRQOL was stronger in men than in women. Implications of these findings for caregiver support programs are discussed.

    With the effective control of hepatitis B infection among children, the adults especial the young ones become the main population for new hepatitis B virus infection. Now the adults receive hepatitis B vaccination voluntarily and at their own expense in China and the coverage is low. The high immunogenicity of hepatitis B vaccine has been proven among healthy adults. Although the safety of hepatitis B vaccination has been documented among high-risk population such as HIV-infected people, injecting drug users and patients with chronic hepatitis disease, their antibody seroconversion rate after hepatitis B vaccination is lower than the healthy adults. Hepatitis B vaccination is recommended to population at high risk officially in many countries and some effects have been achieved. It is urgent to improve the strategy of hepatitis B vaccination among adults to fasten the control of hepatitis B in China, along with the researches about the long-term efficacy of hepatitis B vaccine among adults, the immunogenicity of hepatitis B vaccination among high-risk adults and the economical evaluation about different adult immunization strategy of hepatitis B.

    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.

  18. A digital beacon receiver

    NASA Technical Reports Server (NTRS)

    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.

    1986-01-01

    A longitudinal study of 44 haemophilic children, all in a treatment programme with factor concentrates, was undertaken to evaluate the occurrence, characteristics, and evolution of hepatitis B virus (HBV) infection. Twenty four children (55%) (group I) showed signs of HBV infection, while 20 (45%) (group II) did not. Age at onset of treatment, number of infusions, and total amount of concentrate received did not show significant differences between the two groups. In group I only four children (16%) had symptomatic acute hepatitis. Chronic liver disease was present in nine patients (38% of infected children). The early age of infection would seem to be an important factor for predicting chronic evolution. Evidence of delta infection in three children with severe liver disease seemed to confirm the high pathogenicity of this agent. Because of the risks associated with chronic HBV infection a careful follow up of patients positive for hepatitis B surface antigen is mandatory. PMID:3089179

    The theoretical modeling, materials, and design of the central receiver heat exchanger on the tower of the Themis solar power plant are presented. The receiver was conceived based on the incident solar flux at different times of the day and year and the efficiency of transferring the heat to molten salts. The square aperture admits energy at a peak rate of 3.402 MWth at some points, with heat transfer to the power loop resulting in a maximum efficiency of 25 percent. Optimization studies indicated a receiver inclined 30 deg from the horizontal to face the heliostat field, and the flux incident on the walls was mapped. Tubes filled with the salts at 250 C form the walls behind radiator fins and elevate the salt to temperatures up to a limit of 490 C. Measures taken to allow for the expansion of the cavity walls and to mount the heat exchange tubes for easy replacement are described, along with the instrumentation to measure performance, flux, and detect malfunctions due to perturbations in the fluid flow or failure of any of the components.

    2013-01-01

    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

    Obesity and ectopic fat disposition are risk factors for metabolic disease. Recent data indicate that IGFBP2 expression in liver is epigenetically inhibited during hepatic steatosis. The aim of this study was to investigate if epigenetic de-regulation of hepatic Igfbp2 occurs already early in life and is associated with increased risk for diet-induced obesity (DIO) during adolescence. Male C57BL/6J mice received a high-fat diet. After 3 weeks on this diet (age of 6 weeks), DIO-susceptible (responder, Resp) and DIO-resistant (non-responder, nResp) mice were identified by early weight gain. At the age of 6 weeks, Resp mice exhibited elevated blood glucose (p < 0.05), plasma insulin (p < 0.01), HOMA-IR and leptin/adiponectin ratio, whereas liver triglycerides were identical but significantly increased (p < 0.01) in Resp mice at 20 weeks of age. Igfbp2 expression was reduced in young Resp compared with nResp mice (p < 0.01), an effect that correlated with elevated DNA methylation of intronic CpG2605 (p < 0.01). The epigenetic inhibition of Igfbp2 was stable over time and preceded DIO and hepatosteatosis in adult mice. In vitro studies demonstrated that selective methylation of CpG2605 significantly reduced reporter activity by ∼85%, indicating that Igfbp2 expression is modulated by methylation. In human whole blood cells, methylation of IGFBP2 at the homologous CpG site was increased in obese men with impaired glucose tolerance. In conclusion, our data show that increased methylation of hepatic Igfbp2 during infancy predicts the development of fatty liver later in life and is linked to deterioration of glucose metabolism.

Autophagy is a cellular process that degrades damaged organelles or protein aggregation, which participates in many pathological processes including liver diseases. Autophagy participates in hepatic fibrosis by activating hepatic stellate cells and may participate as well through influencing other fibrogenic cells. Besides that, autophagy can induce some liver diseases to develop while it may play a protective role in hepatocellular abnormal aggregates related liver diseases and reduces fibrosis. With a better understanding of the potential effects of autophagy on hepatic fibrosis, targeting autophagy might be a novel therapeutic strategy for hepatic fibrosis in the near future.

    AIM: To evaluate the efficacy of pegylated interferon in Iranian chronic hepatitis C patients in relation to interferon-λ (IFNL) polymorphisms. METHODS: This study enrolled patients with chronic hepatitis C referred to the Tehran Blood Transfusion Hepatitis Clinic in 2011. Patients were included in the study if they had no concomitant hepatic illness, were negative for human immunodeficiency virus antibodies, and had no prior history of treatment with any type of pegylated interferon. Patients were treated with 180 μg pegylated interferon alpha-2a (Pegaferon®) weekly and 800-1200 mg ribavirin daily for 24 or 48 wk depending on weight and hepatitis C virus (HCV) genotype. Blood samples were collected from patients to obtain DNA for determination of IFNL rs12979860 and rs8099917 polymorphisms. The virologic response in patients was then evaluated and compared between the different IFNL genotypes. RESULTS: A total of 152 patients with a mean age of 41.9 ± 10.0 years were included in the study, of which 141/152 were men (92.8%). The most frequent HCV genotype was type-1, infecting 93/152 (61.2%) patients. Sustained virologic response (SVR) was achieved in 81.9% of patients with HCV genotype-1 and 91.1% of patients with HCV genotype-3. Treatment success was achieved in 91.2% (52/57) of patients with the IFNL rs12979860 CC genotype and 82.1% (78/95) in those with other genotypes. Similar treatment response rates were also observed in patients with rs8099917 TT (39/45; 86.7%) and non-TT (61/68; 89.7%) genotypes. Univariate analyses identified the following factors which influenced treatment response for inclusion in a multivariate analysis: age, HCV RNA level, stage of liver fibrosis, rs12979860 CC genotype, and aspartate transaminase level. A logistic regression analysis revealed that only the rs12979860 CC genotype was significantly associated with achievement of SVR (OR = 6.2; 95%CI: 1.2-31.9; P = 0.03). CONCLUSION: The rs12979860 CC genotype was associated with

  12. 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.

    1994-04-01

    In hospital and clinic management, accounts are valued as units and handled equally--a $20 account receives the same minimum number of statements as a $20,000 account. Quite often, the sheer number of accounts a hospital or clinic has to handle forces executives to manage accounts by default and failure--accounts mature on an aging track and, if left unpaid by patients, eventually are sent to collections personnel. Of the bad-debt accounts placed with collections agencies, many are misclassified as charity or hardship cases, while others could be collected by hospital or clinic staff with a limited amount of additional effort.

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

    PubMed

    Pettus-Davis, Carrie

    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.

    2006-03-24

    In May 2001, the U.S. Food and Drug Administration (FDA) approved Hepatitis A Inactivated and Hepatitis B Recombinant Vaccine (HEPAB) for immunization of adults. From May 2001 to September 2003, the Vaccine Adverse Event Reporting System (VAERS) received 305 reports of adverse events after HEPAB. Many events were similar to those reported after the monovalent hepatitis A and B vaccines. Non-serious events included constitutional symptoms and local reactions. Serious events included neurologic, hepatobiliary, and dermatologic conditions, and detailed medical and epidemiological review did not suggest a clear pattern of evidence supporting a causal relationship with the vaccine, except for injection site reactions and some allergic reactions.

    Little is known about the prevalence of infection with hepatitis viruses in Belize, Central America. We conducted a serologic survey among members of the Belize Defence Force (BDF), which is composed of the five major ethnic groups in Belize, to estimate prevalence rates of hepatitis A, B, and C among military-aged men and women in Belize. Of approximately 600 men and women in the BDF, 492 (82%) completed a questionnaire and blood collection. Antibody to hepatitis A was found in 94%, with similar rates by age, sex, rank, and ethnicity. Antibody to hepatitis B core antigen (anti-HBc) was found in 31%. Rates of anti-HBc varied significantly among the ethnic groups with the lowest rates in Mestizo (5%) and Mayan Indians (9%), and significantly higher rates among Creoles (30%) and Garifuna (56%). Rates increased with increasing age from 28% in those 18-24 years old to 35% in those > or = 35 years old (P = 0.07, by chi-square test for trend). Hepatitis B surface antigen was found in 21 (4%) overall. Antibody to hepatitis C was found in two (0.4%). In this young healthy population, exposure to hepatitis A before the age of 18 is almost universal, while exposure to hepatitis B is related to age and ethnic origin.

    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.

    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.

    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

    Abstract Purpose: Men who have sex with men and are sex workers (MSMSW) are disproportionately affected by the growing and emerging HIV epidemic. As sex work and same-sex behavior are heavily stigmatized and often illegal in most Asian countries, HIV research focusing on MSMSW has been limited. The goal of this analysis is to examine HIV testing practices and identify correlates of HIV testing among MSMSW in Asia. Methods: The Asia Internet MSM Sex Survey, an online cross-sectional survey of 10,861 men who have sex with men (MSM), was conducted in 2010. Data on sociodemographic characteristics, HIV testing behaviors, and sexual behaviors were collected. Five hundred and seventy-four HIV-negative/unknown respondents reported receiving payment for sex with men at least once in the past 6 months and were included in this analysis. Multivariable logistic regression was conducted to identify independent correlates of HIV testing in the past year. Results: About half (48.6%) of the participants had been tested for HIV at least once within the past year, and 30.5% had never been tested. We also found that MSMSW participants who engaged in risky behaviors were less likely to be tested. Conclusion: While one might expect a high HIV testing rate among MSMSW due to the risks associated with engaging in sex work, we found that HIV testing uptake is suboptimal among MSMSW in Asia. These results suggest that targeted HIV prevention and testing promotion among MSMSW are needed. PMID:26982598

    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

  12. Digital Receiver Phase Meter

    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.

    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.

    Co-infection of schistosomiasis, HBV and HCV is common in countries where schistosomiasis is endemic. Occult hepatitis B occurs in patients at high risk for HBV infection (e.g., patients on hemodialysis, patients receiving blood transfusions). Schistosomal infection is a risk factor of HBV infection that can increase the incidence of occult hepatitis B. We aimed to determine the prevalence of occult hepatitis B in chronic hepatitis C patients with and without schistosomiasis and to assess the effect of schistosomal infection on the increased risk of exposure to HBV infection and to occult hepatitis B. Two hundred chronic hepatitis C patients who were negative for HBsAg participated. All patients were tested for the following: Anti-schistosome antibodies, Anti-HBc, serum HBV DNA, CBC and liver function. The prevalence of occult hepatitis B in CHC patients with/without schistosomiasis were 12.8% and 8.5% (P=0.042), respectively. Next, 63.8% of CHC patients with schistosomiasis were exposed to HBV infection (Anti-HBc +ve) during their lifetime. In conclusion, the prevalence of occult hepatitis B is higher in CHC patients with schistosomiasis compared to those without schistosomiasis. Periodic laboratory investigations of Schistosoma mansoni, HBV and HCV are recommended for the early detection of the infection and, especially in endemic areas, to avoid infection complications.

    2015-11-02

    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.

    African American men (AA) carry unequal burdens of several conditions including cancer, diabetes, hypertension, and HIV. Engagement of diverse populations including AA men in research and health promotion practice is vital to examining the health disparities that continue to plague many racially and ethnically diverse communities. To date, there is little research on best practices that indicate locations, community areas and settings to engage AA men in research and health promotion. Traditionally, the AA church has been a key area to engage AA men and women. However, changing tides in attendance of AA parishioners require additional information to identify areas where AAs, particularly, AA men congregate. The AA barbershop has been identified as a place of social cohesion, cultural immersion and solidarity for AA men but specific sub-populations of AA men may be underrepresented. To further investigate additional locales where AA men congregate, this study engaged AA barbers and clients in several urban community barbershops in Chicago, Illinois. 127 AA men over age 18y/o receiving grooming services in 25 Chicago area barbershops across 14 predominantly AA communities were consented and recruited for a quantitative survey study. The self-administered surveys were completed in ~15 min and $10 compensation was provided to men. Descriptive statistics were reported for demographic variables and for frequency of responses for locations to find AA men of specific age ranges for health promotion and screening activities. Outside of the traditionally used churches or barbershops, the top recommended recruitment sites by age were: 18-29y/o- city park or a recreational center; 30-39y/o- gym, bars or the street; 40-49y/o- various stores, especially home improvement stores, and the mall; and 50y/o+- fast food restaurants in the mornings, such as McDonalds, and individual's homes. The study participants also reported that locations where AA men congregate vary by age

    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

    Sarcoidosis is a systemic non caseous granulomas disease. Liver is a common location but usually asymptomatic. Evidence based guidelines for this location treatment is lacking and the effect of corticosteroids may be inadequate. The aim of our study was to describe the clinical, biochemical, radiological and therapeutic features of seven patients with systemic sarcoidosis and liver involvement. A retrospective and descriptive monocentric study, over 3 years, including seven patients with systemic sarcoidosis and liver involvement. We included 5 women and 2 men with an average age of 43 years. Hepatic localization revealed sarcoidosis in 5 cases. Hepatomegaly was observed in all patients as well as abnormal serum liver function test reflected by anicteric cholestasis. Liver biopsy, showed in all granulomatous lesions consistent with sarcoidosis and severe fibrosis in 2 cases. Extra-hepatic manifestations were present in all patients represented mainly by pulmonary location. All patients were treated, five by corticosteroid and two with ursodeoxycholic acid (UDCA). Complete response was observed in one case, partial response in another case and corticosteroid refractoriness in one case. In two cases, corticosteroid therapy was introduced for less than 1 month, not allowing assessment of response. Antimalarials in combination with UDCA were used successfully in a patient with steroid-resistant liver disease. Liver involvement can reveal systemic sarcoidois. Given the risk of progression to severe liver disease, it must be screened in all patients with systemic sarcoidosis. Treatment is not systematic, and still based on corticosteroid therapy. In the absence of prospective randomized controlled trials, the efficacy of UDCA need to be proven. PMID:27795804

    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.

    Viral hepatitis has long been under-diagnosed. Hepatitis A is an acute disease, while patients infected by hepatitis B and hepatitis C viruses are likely to develop chronical infections and severe complications (cancer, cirrhosis). The current treatment of hepatitis B and C consists in alpha interferon (preferably under its pegylated form), in combination with ribavirin for hepatitis C. The frequent and severe adverse effects of interferon-based therapy constitute, however, a major limiting factor (reactions at the injection site, flu-like syndrome, neurological disorders, ...). For hepatitis B, two alternatives are available so far, namely lamivudine and adefovir (used as a prodrug with highe oral bioavailability).

    Hepatic abnormalities are described in three patients who received synthetic anabolic steroids. A child with Franconi's anaemia was treated for four years and at necropsy the liver showed generalized hyperplasia, hyperplastic nodules, and a benign hepatoma. Two adults received only three months' therapy with synthetic androgens; in one there was generalized hepatic hyperplasia and in the other widespread nodular hyperplasia. It is suggested that anabolic steroids may induce tumours through intermediate hyperplastic lesions, a sequence similar to that seen during tumour induction by carcinogens in experimental animals.

    This study presents an experience of application of follicle-stimulating drug in the treatment of men with normogonadotropic infertility. Patients of the study group have received standard treatment, including multivitamins, and additionally received follitropin-alpha (Gonal-f). They also underwent ultraviolet blood irradiation. Patients of comparison group were treated according to a standard scheme. All men underwent standard clinical and laboratory examination. The therapy consisting of follitropin alpha and ultraviolet blood irradiation in patients with infertility normalizes the function of endocrine glands, as indicated by an increase of testosterone levels, and decrease of prolactin and FSH levels. Moreover, there is a marked stimulation of spermatogenesis, as evidenced by a significant increase in the number of active sperm. The results of this study allow to recommend follitropin-alpha (Gonal-f) and ultraviolet blood irradiation for the correction of normogonadotropic treatment in men.

    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

Between February 2003 and December 2004, 83 (9.3%) out of 890 immigrants tested positive for hepatitis B surface antigen. All were men and 62.6% came-from Africa, 21.6% from Asia and 16.8% from Eastern Europe. About half (54.3%) of the patients had elevated alanine aminotransferase levels and detectable serum HBV DNA. Genotype distribution was as follows: E (20 cases), D (14 cases) and A (11 cases). Our study underscores the potential of migratory flow to introduce genotype non-D hepatitis B virus into our country.

    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.

    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.

    Doravirine is a novel, potent, nonnucleoside reverse-transcriptase inhibitor currently in development for HIV-1 infection treatment. As a substrate for CYP3A-mediated metabolism, doravirine could potentially be affected by liver-function changes. As a portion of the HIV-1-infected population has varying degrees of liver impairment, we investigated the effect of moderate hepatic impairment on the pharmacokinetic profile and tolerability of single-dose doravirine 100 mg in otherwise healthy subjects. A total of 16 subjects aged 44-64 years took part in the open-label, single-dose trial: 8 with moderate hepatic impairment (Child-Pugh score, 7-9; 6 men, 2 women) and 8 healthy individuals (mean age and height matched with the impairment group; 6 men, 2 women). Subjects with hepatic impairment were required to have chronic, stable hepatic impairment with features of cirrhosis of any etiology. Blood sampling revealed that doravirine exposure was similar in both groups. The observed geometric least-squares mean ratio (90% confidence interval; moderately impaired/healthy subjects) was 0.99 (0.72-1.35) for AUC0-∞ , 0.93 (0.74-1.18) for AUC0-24 h , 0.90 (0.66-1.24) for Cmax , and 0.99 (0.74-1.33) for C24 h . Geometric mean apparent terminal t½ was ∼18 hours for both groups, whereas median Tmax was 2 hours (range, 1-6 hours) and 2.5 hours (range, 1-3 hours) for impaired and healthy individuals, respectively. In addition, doravirine was generally well tolerated. The results demonstrate that moderate hepatic impairment does not have a clinically meaningful effect on doravirine pharmacokinetics. Therefore, dose adjustment should not be necessary in patients with both HIV-1 and moderate hepatic impairment.

  20. Viral hepatitis and hepatitis B antigen: recent advances

    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

    Hepatitis C virus (HCV) infection is a major health problem in Egypt as the nation bears the highest prevalence rate worldwide. This necessitated establishing a novel model of care (MOC) to contain the epidemic, deliver patient care and ensure global treatment access. In this review, we describe the process of development of the Egyptian model and future strategies for sustainability. Although the magnitude of the HCV problem was known for many years, the HCV MOC only came into being in 2006 with the establishment of the National Committee for Control of Viral Hepatitis (NCCVH) to set up and implement a national control strategy for the disease and other causes of viral hepatitis. The strategy outlines best practices for patient care delivery by applying a set of service principles through identified clinical streams and patient flow continuums. The Egyptian national viral hepatitis treatment programme is considered one of the most successful and effective public health programmes. To date, more than one million patients were evaluated and more than 850 000 received treatment under the umbrella of the programme since 2006. The NCCVH has been successful in establishing a strong infrastructure for controlling viral hepatitis in Egypt. It established a nationwide network of digitally connected viral hepatitis-specialized treatment centres covering the country map to enhance treatment access. Practice guidelines suiting local circumstances were issued and regularly updated and are applied in all affiliated centres. This review illustrates the model and the successful Egyptian experience. It sets an exemplar for states, organizations and policy-makers setting up programmes for care and management of people with hepatitis C.

    This open-label, single-dose study assessed lenvatinib pharmacokinetics (PK) in subjects with normal hepatic function (n = 8) and mild, moderate, or severe hepatic impairment (n = 6 each). Subjects received 10 mg oral lenvatinib, except those with severe hepatic impairment (5 mg). Plasma and urine samples were collected over 14 days; free and total lenvatinib and its metabolites were analyzed using validated chromatography/spectrometry. PK parameters were estimated using noncompartmental analysis. There were no clinically meaningful effects of mild or moderate hepatic impairment on lenvatinib PK. Dose-normalized Cmax for free lenvatinib was 7.0, 3.7, 5.7, and 5.6 ng/mL in subjects with normal hepatic function, mild, moderate, and severe hepatic impairment, respectively. There was no consistent trend, although dose-normalized Cmax was lower for all subjects with hepatic impairment. AUCs increased 170% and t1/2 increased (37 versus 23 hours) in subjects with severe hepatic impairment. Changes in exposure based on total plasma concentrations were generally less than those based on free concentrations, suggesting changes in plasma protein binding in subjects with severe hepatic impairment. Lenvatinib was generally well tolerated. Subjects with severe hepatic impairment should begin lenvatinib treatment at a reduced dose of 14 mg versus 24 mg for subjects with normal liver function and subjects with mild or moderate hepatic impairment.

    2009-01-01

    Insulin is an important regulator of glucose, lipid and protein metabolism. It suppresses hepatic glucose and triglyceride production, inhibits adipose tissue lipolysis and whole-body and muscle proteolysis and stimulates glucose uptake in muscle. In this review we discuss what is currently known about the control of substrate metabolism by insulin in men and women. The data available so far indicate that women are more sensitive to insulin with regards to glucose metabolism (both in the liver and in muscle) whereas there are no differences between men and women in insulin action on lipolysis. Potential differences exist in the regulation of plasma triglyceride concentration and protein metabolism by insulin and in changes in insulin-action in response to stimuli (e.g., weight loss and exercise) that are known to alter insulin sensitivity. However, these areas have not been studied comprehensively enough to draw firm conclusions. PMID:20392600

    OBJECTIVE: To determine the prevalence and risk factors for hepatitis B virus (HBV) infections among individuals attending an STD clinic in a low endemic region. STUDY DESIGN: A total of 1228 women and 1648 men attending the STD clinic at the University Hospital Rotterdam, Netherlands, were examined for HBV infection by determination of hepatitis B surface antigen (HBsAg) and antibodies to hepatitis B core antigen (anti-HBc). Demographic characteristics, information on sexual behaviour, and intravenous drug use were recorded. RESULTS: The seroprevalence of HBsAg was 1.4% in women and 2.1% in men (0% in homosexual men). The seroprevalence of anti-HBc was 13% in women and 20% in men (36% in homosexual men). Native country, intravenous drug use, a history of STD, and the number of partners in the past half year (inversely) were independent risk factors for HBsAg positivity in women and heterosexual men. For anti-HBc independent associations were observed for native country, age, intravenous drug use, commercial sex, number of lifetime partners, homosexual contacts, orogenital contact (inverse), and a history of STD. CONCLUSION: The HBV prevalence in the STD clinic attendants was high, exceeding the national estimate, and indicates that the STD clinic population may be considered a high risk group. Our data confirmed an increased risk for HBV infections among established risk groups. Therefore, these risk groups should be routinely screened to identify HBV cases for counselling and contact tracing. PMID:9582467

    Background In Hepatitis C virus (HCV) mono-infection, male sex is associated with faster liver fibrosis progression but the effects of sex have not been well studied in HIV-HCV co-infected patients. 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

    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

    2011-06-01

    The term minimal hepatic encephalopathy (MHE) refers to the subtle changes in cognitive function, electrophysiological parameters, cerebral neurochemical/neurotransmitter homeostasis, cerebral blood flow, metabolism, and fluid homeostasis that can be observed in patients with cirrhosis who have no clinical evidence of hepatic encephalopathy; the prevalence is as high as 84% in patients with hepatic cirrhosis. Physician does generally not perceive cirrhosis complications, and neuropsychological tests and another especial measurement like evoked potentials and image studies like positron emission tomography can only make diagnosis. Diagnosis of minimal hepatic encephalopathy may have prognostic and therapeutic implications in cirrhotic patients. The present review pretends to explore the clinic, therapeutic, diagnosis and prognostic aspects of this complication.

    2006-11-01

    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.

    Liver injuries may be due to either blunt or penetrating trauma to the thorax or abdomen. Specific treatment depends on the site and extent of hepatic injury. Following resuscitation with intravenous fluids and blood as needed, surgical therapy is directed to provide hemostasis, remove necrotic liver tissue and promote adequate external drainage in the postoperative period. While local measures are usually sufficient, complex hepatic wounds may require extensive resection and vascular ligature or repair. PMID:890631

    Human leukocyte antigen (HLA) class II molecules are associated with host immune responses against hepatitis B virus infection. Male gender is the apparent host factor when someone encounters with the severity of hepatitis. The aim of this study was to investigate the association of the most polymorphic HLA class II allele, human leukocyte antigen-DRB1, with the severity of hepatitis in male carriers of hepatitis B virus. In this prospective cohort study, a total of 204 carriers of hepatitis B virus (131 men and 73 women) who have been followed-up for more than 1 year at the outpatient clinic of a university hospital were collected consecutively. Fifty carriers of hepatitis B virus (group I) with alanine aminotransferase <2x upper limit of normal (mean follow-up 83.6 months) were compared with 154 chronic hepatitis B patients (group II) with alanine aminotransferase >/=2x upper limit of normal (mean follow-up 81.3 months). Alleles of HLA-DRB1 were typed by the polymerase chain reaction-sequence specific oligonucleotide probe hybridization and genotypes of hepatitis B virus by melting curve analysis. HLA-DRB1*1101 was found in 18% of group I versus 8% of group II in male carriers (OR 0.23, P = 0.020, after adjustment for age) and 4% versus 9.4% in female carriers (P = 0.094). In male carriers harboring DRB1*1101, the distribution of hepatitis B viral genotype was comparable between the two groups. HLA-DRB1*1101 correlates with less severe hepatitis in Taiwanese male carriers of hepatitis B virus.

    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.

  2. Mechanisms of Hepatic Fibrogenesis

    PubMed Central

    Friedman, Scott L.

    2010-01-01

    Substantial improvements in the treatment of chronic liver disease have accelerated interest in uncovering the mechanisms underlying hepatic fibrosis and its resolution. Activation of resident hepatic stellate cells into proliferative, contractile, and fibrogenic cells in liver injury remains a dominant theme driving the field. However, several new areas of rapid progress in the past 5–10 years also have taken root, including: (1) identification of different fibrogenic populations apart from resident stellate cells, for example, portal fibroblasts, fibrocytes, and bone-marrow– derived cells, as well as cells derived from epithelial mesenchymal transition; (2) emergence of stellate cells as finely regulated determinants of hepatic inflammation and immunity; (3) elucidation of multiple pathways controlling gene expression during stellate cell activation including transcriptional, post-transcriptional, and epigenetic mechanisms; (4) recognition of disease-specific pathways of fibrogenesis; (5) re-emergence of hepatic macrophages as determinants of matrix degradation in fibrosis resolution and the importance of matrix cross-linking and scar maturation in determining reversibility; and (6) hints that hepatic stellate cells may contribute to hepatic stem cell behavior, cancer, and regeneration. Clinical and translational implications of these advances have become clear, and have begun to impact significantly on the management and outlook of patients with chronic liver disease.

    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.

    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.

    Background & aims Virological breakthrough (VBT) could be a manifestation of chronic hepatitis B (CHB) in patients treated with long-term nucleot(s)ide analogues. We aimed to determine the association of on-treatment serum hepatitis B virus (HBV) DNA with VBT in HBeAg-positive CHB patients receiving entecavir (ETV) treatment. Methods A retrospective cohort study, including 162 consecutive patients (95 men and 67 women; mean age, 43.1±13.4 years) with HBeAg-positive CHB treated with ETV for at least 48 weeks between August 2008 and May 2015, was conducted. Univariate and multivariate cox regression analysis were used to identify associations with VBT and clinical factors, including HBV DNA and HBeAg serum status. Results Among the 162 ETV-treated HBeAg-positive CHB patients, eighteen patients (11.1%) experienced VBT (VBT group), whereas the other 144 patients were without VBT (non-VBT group). The cumulative rate of HBV DNA < 100 IU/mL in the VBT group and the non-VBT group at week 48 were 44.44% and 70.14%, and at week 96 were 58.33% and 92.56%, respectively (p = 0.015). The cumulative rate of HBeAg seroclearance in the VBT group and non-VBT group at week 48 and week 96 were statistically significant (p = 0.014). Multivariate analysis disclosed that failure to achieve HBeAg seroclearance were the factors significantly associated with VBT. Conclusions Our results demonstrated that on-treatment HBV DNA could probably predict VBT in ETV-treated HBeAg-positive chronic hepatitis B patients. Failure to achieve HBeAg seroclearance was associated with VBT in ETV-treated HBeAg-positive CHB patients. HBV DNA >100IU/mL at 48 weeks is potentially a predictor for VBT. PMID:28350873

    Fasting promotes triglyceride (TG) accumulation in lean tissues of some animals, but the effect in humans is unknown. Additionally, fasting lipolysis is sexually dimorphic in humans, suggesting that lean tissue TG accumulation and metabolism may differ between women and men. This study investigated lean tissue TG content and metabolism in women and men during extended fasting. Liver and muscle TG content were measured by magnetic resonance spectroscopy during a 48-h fast in healthy men and women. Whole-body and hepatic carbohydrate, lipid, and energy metabolism were also evaluated using biochemical, calorimetric, and stable isotope tracer techniques. As expected, postabsorptive plasma fatty acids (FAs) were higher in women than in men but increased more rapidly in men with the onset of early starvation. Concurrently, sexual dimorphism was apparent in lean tissue TG accumulation during the fast, occurring in livers of men but in muscles of women. Despite differences in lean tissue TG distribution, men and women had identical fasting responses in whole-body and hepatic glucose and oxidative metabolism. In conclusion, TG accumulated in livers of men but in muscles of women during extended fasting. This sexual dimorphism was related to differential fasting plasma FA concentrations but not to whole body or hepatic utilization of this substrate.

    Enhanced Sexual Health Services (ESHS) have the potential to widen access to sexual health services for populations in England. This study aimed to identify what provision was commissioned in ESHS for men who have sex with men (MSM). We undertook a web-based survey of Primary Care Trust (PCT) commissioners in the south-east of England, exploring what sexual health services were commissioned for MSM and comparing them with published standards. Fourteen of 17 PCTs (82%) responded. All PCTs identified at least one genitourinary (GU) medicine clinic and 13 identified at least one ESHS commissioned for their population. However no single ESHS provided the full range of essential services for MSM. Testing for Chlamydia (84.6% PCTs) and for HIV (69.2% PCTs) were most commonly provided in ESHS, while only 46% and 62% of PCTs had an ESHS commissioned to provide gonorrhoea testing and hepatitis B/syphilis serology testing respectively. Under two-thirds reported training of staff in the sexual health needs of MSM. ESHS are not commissioned to provide the full range of essential sexual health services for MSM. This needs to be addressed by improving staff training in these services and strengthening care pathways between ESHS and GU medicine clinics.

    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.

    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

    1993-01-01

    Fulminant hepatitis due to herpes simplex virus (HSV) in adults is a rare and deadly disease. We describe a 23-year-old woman with a 20-year history of Crohn's disease (CD) who was hospitalized with an acute febrile illness and diarrhea. A computed tomography (CT) scan of the abdomen demonstrated an intramural sigmoid colon abscess and multiple abscesses in the liver. Despite high-dose parenteral corticosteroids and broad-spectrum antibiotics, the patient remained acutely ill, with high fever and markedly elevated serum transaminase levels, but no jaundice. Sigmoid resection and wedge liver biopsy were performed at laparotomy. Histologic examination documented HSV-type intranuclear inclusions and inflammation with necrosis in both the sigmoid colon and liver specimens. The patient subsequently died despite parenteral acyclovir treatment. Although rare, fulminant hepatitis due to HSV simplex virus should be considered in the differential diagnosis of all patients with severe hepatitis. Of special note, the necrotizing liver lesions may be mistaken for pyogenic abscesses on CT scan.

    2013-01-01

    Hepatic encephalopathy has been listed as a differential for llamas displaying neurologic signs, but it has not been histopathologically described. This report details the neurologic histopathologic findings associated with 3 cases of hepatic lipidosis with concurrent neurologic signs and compares them to 3 cases of hepatic lipidosis in the absence of neurologic signs and 3 cases without hepatic lipidosis. Brain from all 3 llamas displaying neurologic signs contained Alzheimer type II cells, which were not detected in either subset of llamas without neurologic signs. Astrocytic immunohistochemical staining intensity for glial fibrillary acid protein was decreased in llamas with neurologic signs as compared to 2 of 3 llamas with hepatic lipidosis and without neurologic signs and to 2 of 3 llamas without hepatic lipidosis. Immunohistochemical staining for S100 did not vary between groups. These findings suggest that hepatic encephalopathy may be associated with hepatic lipidosis in llamas.

    Engaging in regular physical activity reduces one's risk of chronic disease, stroke, cardiovascular disease, and some forms of cancer. These preventive benefits associated with physical activity are of particular importance for men, who have shorter life expectancy and experience higher rates of chronic diseases as compared to women. Studies at the community and national levels have found that social and environmental factors are important determinants of men's physical activity, but little is known about how regional influences affect physical activity behaviors among men. The objective of this study is to examine the association between geographic region and physical activity among men in the United States, and to determine if there are racial/ethnic differences in physical activity within these geographic regions. Cross-sectional data from men who participated the 2000 to 2010 National Health Interview Survey ( N = 327,556) was used. The primary outcome in this study was whether or not men had engaged in sufficient physical activity to receive health benefits, defined as meeting the 2008 Physical Activity Guidelines for Americans. Race/ethnicity and geographic region were the primary independent variables. Within every region, Hispanic and Asian men had lower odds of engaging in sufficient physical activity compared to white men. Within the Northeast, South, and West, black men had lower odds of engaging in sufficient physical activity compared to white men. The key findings indicate that the odds of engaging in sufficient physical activity among men differ significantly between geographic regions and within regions by race/ethnicity.

    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.

    52 elderly women and 36 matched by age and education men with initiatory stages of chronic brain ischemia (CBI) have been studied using comparative analysis of personality characteristics. Women with CBI had higher level of psychosocial stress than men. The results demonstrate the predomination of extrapunitive frustration reactions among women. Intropunitive ones prevailed in men. Women-patients had higher levels of excitement, stress and anxiety than men that surpassed women by the indicators of emotional security. The received data may be important for individualization of therapeutic intervention.

    The aim of this study was to determine the efficacy of immunization against hepatitis A and B infections with "rapid" or "accelerated" schedules in children with cancer receiving chemotherapy. Fifty-one children were recruited to receive either vaccination schedule, in the "rapid vaccination schedule"; hepatitis B (group I) or combined hepatitis A/B vaccines (group III) were administered at months 0, 1, 2, and 12; in the "accelerated vaccination schedule," hepatitis B (group II) or combined hepatitis A/B (group IV) vaccines were administered on days 0, 7, 21, and 365 intramuscularly. The seroconversion rates at months 1 and 3 were 35.7 and 57.1% in group I and 25 and 18.8% in group II, respectively. Group I developed higher seroconversion rates at month 3. In group III the seroconversion rates for hepatitis B at months 1 and 3 were 54.5 and 60% and in group IV 50 and 70%, respectively. For hepatitis A, the seroconversion rates at months 1 and 3 were 81.8 and 90% in group III and 80 and 88.9% in group IV, respectively. The accelerated vaccination schedule seems to have no advantage in children receiving cancer chemotherapy except for high antibody levels at month 1. In conclusion, the accelerated vaccination schedules are not good choices for cancer patients. The combined hepatitis A/B vaccine is more effective than monovalent vaccine in cancer patients, which probably can be explained by an adjuvant effect of the antigens. The seroconversion of hepatitis A by the combined hepatitis A/B vaccination is very good in cancer patients.

    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.

    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

    2015-01-01

    Background Human papillomavirus (HPV) is a common sexually transmitted infection that causes anal, penile, and oropharyngeal cancers in men. Men who have sex with men (MSM) are at particularly high risk for HPV infection and HPV-related disease. HPV vaccination is currently recommended for all MSM in the U.S. through age 26 years, yet little is known about HPV vaccine uptake in this population. The purpose of this study was to identify predictors of HPV vaccine uptake and barriers and facilitators to HPV vaccination that may be unique to young MSM. Methods Men aged 18–26 years (N=336) were recruited via advertisements placed on a geospatial smartphone dating application designed for MSM. Participants completed an online survey. Correlates of vaccine uptake and provider recommendation for HPV vaccine were identified using logistic regression. Results In total, 21% of participants had received ≥1 dose of HPV vaccine. Provider recommendation was the strongest predictor of uptake such that MSM with a recommendation were over 40 times more likely to have been vaccinated. Additional predictors of uptake included age and HPV vaccine attitudes. Predictors of provider recommendation included sexual identity, race/ethnicity, condomless anal sex, and HIV status. Psychosocial correlates and barriers and facilitators to HPV vaccination among unvaccinated men were also identified. Conclusions Findings highlight potential disparities in HPV vaccine uptake, as well as disparities in provider recommendation practices for HPV vaccination. Future interventions should aim to clarify misconceptions, modify psychosocial beliefs, and address barriers and facilitators to HPV vaccine uptake specific to young MSM. PMID:26859806

    There has been limited previous research that has examined the role of sociocultural influences on body change strategies among adult men. The current study investigated the role of specific types of messages (encouragement, teasing and modelling) from peers and the media on the strategies to change weight among adult men. Differences were evaluated between 526 men aged from 18 to 60 years from three groups (normal weight, overweight and obese) on body image, body change strategies and messages about their body received from peers and the media. Men were primarily drawn from United States, Australia and Europe. Results showed that messages received by men regarding losing weight or increasing muscle size differed according to weight. Body image and media messages were the strongest predictors of losing weight, whereas body image importance and messages from peers were the strongest predictors of increasing muscles. These findings highlight the importance of sociocultural influences on body change strategies among adult males.

    The purposes of this study were to determine whether exposure of the vestigial male breast to ionizing radiation is associated with an increase in risk of breast cancer and, if so, to determine whether the apparent effects on risk in men are similar to those reported for women. A population-based case-control study of breast cancer in men was conducted in 10 geographic areas of the United States. Information on possible prior exposure to ionizing radiation, and on other potential risk factors for breast cancer, was obtained from personal interviews of 227 cases and 300 controls who were recruited from October 1983 to September 1986. Evidence from this study that ionizing radiation can cause breast cancer in men includes: a modest trend of increasing risk with frequency of chest X-rays; an increase in risk in men with three or more radiographic examinations, especially if received prior to 1963; and an increase in risk in men who received X-ray treatments to the chest and adjacent body areas. Risk was increased only from 20 to 35 years after initial exposure from either radiographic examinations or X-ray treatments, and declined after three to four decades since last exposure, suggesting a wave of increased risk of finite duration following exposure. The doses of radiation received could not be estimated precisely, but those from diagnostic procedures were likely similar to those received by prepubertal females in prior studies, and the results of those and the present investigation are compatible. The carcinogenic effects of ionizing radiation may be similar in the male and prepubertal female breast.

    The Hepatitis B vaccine is highly effective for the prevention of hepatitis B (HBV) infection. We report the development of chronic HBV infection (Genotype F) in a vaccinated immunocompetent individual with an anti-HBsAb of 35 mIU/mL post completion of vaccine series. HBV vaccine is based on recombinant proteins of genotype-A and D (predominant genotypes in Europe). It may not be as effective for the prevention of more genetically diverse viruses such as genotype F (predominant genotype in Central and South America). Healthcare providers and patients should be aware that the HB vaccine does not confer 100% protection against HBV infection, even in the setting of protective antibody levels. Partners of individuals infected with non-A or -D genotypes should be advised to consider additional precautions to prevent transmission even in the setting protective antibody levels. Surveillance of circulating HBV genotypes should be undertaken to inform public health policy in relation to prevention of HB in high-risk groups such as men who have sex with men.

    Background Directly disclosing a positive HIV serostatus to family members can affect psychological and disease status. Perceptions that one is in a supportive family environment may moderate these effects; however, ethnic differences may exist in the support processes of families coping with HIV. Methods We examined the role of serostatus disclosure to parents, HIV-specific family support, and ethnicity (Latino versus non-Hispanic White) in explaining disease status (HIV Viral Load, CD4+ cell count) in a sample of men living with HIV (MLWH). Men (n = 120) reported whether they had disclosed their serostatus to their mothers and fathers, rated their perceptions of HIV-specific social support received from family members, and provided morning peripheral venous blood samples to assess immune function. We also collected psychosocial and urinary neuroendocrine indicators of stress/distress as possible mediator variables. Results A three-way interaction emerged between serostatus disclosure to mothers, HIV-specific family support, and ethnicity in explaining both viral load and CD4+ cell count. Non-Hispanic White men who had disclosed to mothers and were receiving high family support had a lower viral load and higher CD4+ cell count, but Latino men who had disclosed to mothers and were receiving low family support had a higher viral load. These associations were not accounted for by men's medication adherence, psychological distress, or neuroendocrine hormones. Disclosure to fathers was not related to disease status. Conclusions The effects of serostatus disclosure on disease status may depend, in part, on ethnic differences in the interpersonal processes of men's close family relationships. PMID:19486655

    Background HIV-1 and Hepatitis B and C viruses coinfection is common in Sub-Saharan Africa due to similar routes of transmission and high levels of poverty. Most studies on HIV-1 and Hepatitis B and C viruses have occurred in hospital settings and blood transfusion units. Data on Hepatitis B and C viruses and HIV-1 coinfection in informal urban settlements in Kenya are scanty, yet they could partly explain the disproportionately high morbidity and mortality associated with HIV-1 infections in these slums. Objectives The objective of this study was to determine the prevalence of HIV and Hepatitis B and C dual infection in urban slums in Nairobi. Methods Blood samples were collected from residents of Viwandani and Korogocho between 2006 and 2007. A structured questionnaire was used to obtain socio-demographic data from participants. Samples were screened for Hepatitis B surface antigen (HBsAg), anti-HCV and anti-HIV-1. Statistical analysis was done using STATA. Results Samples were successfully collected from 418 (32%) men and 890 (68%) females. The HIV-1, HBV and HCV prevalence was 20.4%, 13.3% and 0.76% respectively at the time of the study. Of the 268 (20.4%) HIV-1 positive participants, 56 (4.26%) had HBV while 6 (0.46%) had HCV. Of the 1041 HIV-1 negative participants, 117 (8.9%) had HBV while 4 (0.31%) had HCV. Only two people (0.15%) were co-infected with all the three viruses together. Discussion The odds of getting hepatitis infection were higher in HIV-1 participants (for HBV OR 2.08,p<0.005 and for HCV OR 5.93, p<0.005). HIV prevalence rates were similar in both informal settlements. HIV infection was highest in age group 35-39 years and among the divorced/separated or widowed. Prevalence of all viruses was highest in those who did not have any formal education. Conclusion The HIV prevalence in these informal settlements suggests a higher rate than what is observed nationally. The prevalence rates of HBV are significantly higher in the HIV-1 positive and

    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.

  17. Hepatitis A and B immunizations of individuals infected with human immunodeficiency virus.

    2005-10-01

    All persons at risk for infection with human immunodeficiency virus (HIV) types 1 and 2, including men who have sex with men, those with multiple heterosexual contacts, abusers of illegal injection drugs, and persons frequently exposed to blood and blood products, are also at high risk for hepatitis A virus (HAV) and acute and chronic hepatitis B virus (HBV) infections. HIV can prolong the duration and increase the level of HAV viremia and augment HAV-related liver abnormalities. HIV also magnifies HBV viremia and the risk of HBV reactivation, chronic active HBV infection, cirrhosis, and death. Because of these concerns, hepatitis A vaccination is recommended for all HIV-positive/HAV seronegative persons, with 2 standard doses given 6 to 12 months apart. Immune response to hepatitis A vaccines is excellent, even in moderately immune-suppressed individuals. Hepatitis B vaccination is also recommended for all HIV-positive persons lacking prior immunity. However, immune reactivity to hepatitis B vaccines is frequently suboptimal in terms of patients' rate of response, antibody titer, and durability. Relatively high CD4+ T-cell counts (> or =500/mm3) and low levels of HIV viremia (<1,000 RNA genome copies/mL plasma) are necessary to ensure adequate hepatitis B vaccine response. Higher hepatitis B vaccine doses, prolongation of the vaccination schedule, or both, as prescribed for many patients with non-HIV-related immune deficiencies, may be considered initially. Revaccination should be instituted if postvaccination titers of antibodies to hepatitis B surface antigen are <10 mIU/mL (<10 IU/L). Nonresponders may also react to a subsequent vaccine course if CD4+ T-cell counts rise to 500/mm3 following institution of highly active antiretroviral therapy; vaccine adjuvant trials are under way. Universal, age-based immunization of all young and middle-aged adults appears to be the most comprehensive way of protecting all populations who are at high risk.

  19. Ribavirin in the treatment of hepatitis C.

    Abonyi, Margit E; Lakatos, Peter L

    2005-01-01

    The hepatitis C virus (HCV) is a major cause of chronic liver disease worldwide, with approximately 170-200 million people infected. The HCV virus is transmitted by blood and blood products and such transmission occurs primarily through drug use by injection, sex with an infected partner and occupational exposure. The severity of the disease varies widely from mild chronic hepatitis to cirrhosis and hepatocellular carcinoma (HCC). Nowadays, the reference treatment is combination therapy of pegylated interferon and ribavirin, which is an inosine monophosphate dehydrogenase inhibitor and immunomodulator. Efficacy of treatment in our clinical trials is 87% in patients infected by HCV genotypes 2 or 3, whereas in patients infected by HCV genotype 1 response to treatment is 66%. The current combination treatment has significant side-effects and sometimes is poorly tolerated. HCV genotypes 2 or 3 can be treated with a lower dose of ribavirin and a shorter course of therapy, 24 weeks vs 48 weeks for patients with genotype 1. There is a growing consensus that acute control of HCV infection is associated with a vigorous intrahepatic antiviral CD4+ and CD8+ T-cell response, enhanced Th1 and natural killer activity. Pretreatment genotype and response to therapy measured at weeks 12 and 24 of treatment have been identified as key determinants in decisions about continuing treatment. Elevated serum ferritin levels and hepatic iron deposition as well as hepatic steatosis and high ALT levels with chronic hepatitis C are risk factors for HCC development. Heterozygosityfor the C282Y mutation in HFE contributes to iron accumulation and fibrosis progression in chronic hepatitis C. Ribavirin could cause dose-dependent reversible haemolytic anaemia, which can be managed with dose reductions or with administration of epoetin alpha at 40,000 IU once weekly without sacrificing the optimal dosing of ribavarin. Among patients who received ribavirin alone, serum ALT levels and

    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.

  1. Hepatitis B virus and its sexually transmitted infection - an update

    PubMed Central

    Inoue, Takako; Tanaka, Yasuhito

    2016-01-01

    Epidemiology: incidence and prevalence: About 5% of the world’s population has chronic hepatitis B virus (HBV) infection, and nearly 25% of carriers develop chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). The prevalence of chronic HBV infection in human immunodeficiency virus (HIV)-infected individuals is 5%-15%; HIV/HBV coinfected individuals have a higher level of HBV replication, with higher rates of chronicity, reactivation, occult infection, and HCC than individuals with HBV only. The prevalence of HBV genotype A is significantly higher among men who have sex with men (MSM), compared with the rest of the population. Molecular mechanisms of infection, pathology, and symptomatology: HBV replication begins with entry into the hepatocyte. Sodium taurocholate cotransporting polypeptide was identified in 2012 as the entry receptor of HBV. Although chronic hepatitis B develops slowly, HIV/HBV coinfected individuals show more rapid progression to cirrhosis and HCC. Transmission and protection: The most common sources of HBV infection are body fluids. Hepatitis B (HB) vaccination is recommended for all children and adolescents, and all unvaccinated adults at risk for HBV infection (sexually active individuals such as MSM, individuals with occupational risk, and immunosuppressed individuals). Although HB vaccination can prevent clinical infections (hepatitis), it cannot prevent 100% of subclinical infections. Treatment and curability: The goal of treatment is reducing the risk of complications (cirrhosis and HCC). Pegylated interferon alfa and nucleos(t)ide analogues (NAs) are the current treatments for chronic HBV infection. NAs have improved the outcomes of patients with cirrhosis and HCC, and decreased the incidence of acute liver failure. PMID:28357379

    Alcoholic hepatitis is an acute manifestation of alcoholic liver disease with mortality as high as 40-50% in severe cases. Patients usually have a history of prolonged alcohol abuse with or without a known history of liver disease. Although there is significant range in severity at presentation, patients with severe alcoholic hepatitis typically present with anorexia, fatigue, fever, jaundice, and ascites. The use of either pentoxifylline or corticosteroids in those with severe disease (Maddrey's discriminate function >32) has significant mortality benefit. The addition of N-acetylcysteine to corticosteroids decreases the incidences of hepatorenal syndrome, infection, and short-term mortality, but does not appear to significantly affect 6-month mortality. Nutritional support with high-calorie, high-protein diet is recommended in all patients screening positive for malnutrition. Liver transplantation for a highly selected group of patients with severe alcoholic hepatitis may be an option in the future, but is not currently recommended or available at most transplant institutions.

    Primary hepatic carcinoid tumor is rare and poses a challenge for diagnosis and management. We presented a case of primary hepatic carcinoid tumor in a 53-year-old female with a complaint of right upper abdominal pain. Computer tomography scans revealed a hypervascular mass in segment 4 of the liver. An ultrasonography-guided biopsy showed a carcinoid tumor. No other lesions were found by the radiological investigations. Surgery resection was performed and histopathological examination revealed a primary hepatic carcinoid tumor. Three years later, recurrence was found and transcatheter arterial chemoembolization was performed. After transcatheter arterial chemoembolization, the patient has been free of symptom and had no radiological disease progression for over 6 months. Surgical resection combination with transcatheter arterial chemoembolization is effective to offer excellent palliation.

    The hepatitis E virus (HEV) the causative agent of hepatitis E, is a non-enveloped RNA virus. HEV is transmitted through oral consumption of contaminated food and water According to the currently knowledge now be considered as zoonosis. The main reservoir of HEV are pigs, boars and deer. For the first time HEV was isolated from animals (pigs) in 1997 in the U.S. Genetic analysis of strains isolated from pigs showed high similarity to strains HEV isolated from humans. This was the first evidence showing that HEV is a zoonosis. Further studies have shown that occupational groups e.g. veterinarians, swine breeders with close contact to pigs have an increased risk for HEV infections. The additional evidence supported the zoonotic potential of HEV were reports of acute hepatitis E after the consumption of undercooked meat from deer and wild boar. Infection of HEV in the domestic pig and wild boar population in Europe is widespread.

  6. Neonatal hepatitis syndrome.

    Conjugated hyperbilirubinaemia in an infant indicates neonatal liver disease. This neonatal hepatitis syndrome has numerous possible causes, classified as infective, anatomic/structural, metabolic, genetic, neoplastic, vascular, toxic, immune and idiopathic. Any infant who is jaundiced at 2-4 weeks old needs to have the serum conjugated bilirubin measured, even if he/she looks otherwise well. If conjugated hyperbilirubinaemia is present, a methodical and comprehensive diagnostic investigation should be performed. Early diagnosis is critical for the best outcome. In particular, palliative surgery for extrahepatic biliary atresia has the best chance of success if performed before the infant is 8 weeks old. Definitive treatments available for many causes of neonatal hepatitis syndrome should be started as soon as possible. Alternatively, liver transplantation may be life saving. Supportive care, especially with attention to nutritional needs, is important for all infants with neonatal hepatitis syndrome.

    Hepatitis B virus (HBV) infection is a major global health problems leading to severe liver disease such as cirrhosis and hepatocellular carcinoma (HCC). HBV is a circular, partly double-stranded DNA virus with various serological markers: hepatitis B surface antigen (HBsAg) and anti-HBs, anti-HBc IgM and IgG, and hepatitis B e antigen (HBeAg) and anti-HBe. It is transmitted by sexual, parenteral and vertical route. One significant method to diminish the burden of this disease is timely diagnosis of acute, chronic and occult cases of HBV. First step of HBV diagnosis is achieved by using serological markers for detecting antigens and antibodies. In order to verify first step of diagnosis, to quantify viral load and to identify genotypes, quantitative or qualitative molecular tests are used. In this article, the serological and molecular tests for diagnosis of HBV infection will be reviewed. PMID:27761442

    Obesity and metabolic syndrome pose significant risk for progression of many types of chronic illnesses, including liver disease. Hormones released from adipocytes, adipocytokines, associated with obesity and metabolic syndrome, have been shown to control hepatic inflammation and fibrosis. Hepatic fibrosis is the final common pathway that can result in cirrhosis, and can ultimately require liver transplantation. Initially, two key adipocytokines, leptin and adiponectin, appeared to control many fundamental aspects of the cell and molecular biology related to hepatic fibrosis and its resolution. Leptin appears to act as a profibrogenic molecule while adiponectin possesses strong-anti-fibrotic properties. In this review, we emphasize pertinent data associated with these, and recently discovered, adipocytokines that may drive or halt the fibrogenic response in the liver. PMID:25656826

    American men who have sex with men (MSM) continue to have increased rates of HIV and sexually transmitted diseases (STD). Between 2004 and 2010, 1155 MSM were tested for HIV and/or STDs at Providence, RI bathhouse. The prevalence of HIV was 2.3%; syphilis, 2.0%; urethral gonorrhea, 0.1%; urethral chlamydia, 1.3%; 2.2% of the men had hepatitis C antibodies. Although 43.2% of the men engaged in unprotected anal intercourse in the prior 2 months, the majority of the men thought that their behaviors did not put them at increased risk for HIV or STDs. Multivariate analyses found that men who engaged in unprotected anal intercourse were more likely to have had sex with unknown status or HIV-infected partners; have sex although under the influence of drugs; tended to find partners on the internet; and were more likely to have a primary male partner. Men who were newly diagnosed with HIV or syphilis tended to be older than 30 years; had sex with an HIV-infected partner; had a prior STD diagnosis; and met partners on the internet. For 10.5% of the men, bathhouse testing was the first time that they had ever been screened for HIV. Of 24 men who were newly diagnosed with HIV infection, only 1 was not successfully linked to care. These data suggest that offering HIV and STD testing in a bathhouse setting is effective in attracting MSM who are at increased risk for HIV and/or STD acquisition or transmission.

    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

    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.

    1997-01-01

    Hepatitis G virus (HGV) and GB virus C (GBV-C) are two newly discovered viral agents, different isolates of a positive-sense RNA virus that represents a new genus of Flaviviridae. The purpose of this review is to analyze new data that have recently been published on the epidemiology and associations between HGV and liver diseases such as posttransfusion hepatitis, acute and chronic non-A-E hepatitis, fulminant hepatitis, cryptogenic cirrhosis, and hepatocellular carcinoma. The role of HGV in coinfection with other hepatitis viruses, the response to antiviral therapy, and the impact of HGV on liver transplantation are also discussed. HGV is a transmissible blood-borne viral agent that frequently occurs as a coinfection with other hepatitis viruses due to common modes of transmission. The prevalence of HGV ranges from 0.9 to 10% among blood donors throughout the world and is found in 1.7% of volunteer blood donors in the United States. The majority of patients infected with HGV by blood transfusion do not develop chronic hepatitis, but hepatitis G viremia frequently persists without biochemical evidence of hepatitis. Serum HGV RNA has been found in 0 to 50% of patients with fulminant hepatitis of unknown etiology and 14 to 36% of patients with cryptogenic cirrhosis. The association between HGV and chronic non-A-E hepatitis remains unclear. Although HGV appears to be a hepatotrophic virus, its role in independently causing acute and chronic liver diseases remains uncertain. PMID:9265860

    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

    Testosterone has been used in testicular and hypothalamo-pituitary diseases since the 1940s. There is growing interest in the use of testosterone in aging men, and this has stimulated research into the benefits of male hormone replacement. Testosterone treatment of men with hypogonadism might have beneficial effects on body composition, muscle strength, sexual function, and cognition. There are several modes of administration of the male hormone, with injectable testosterone esters and implanted testosterone pellets being the mainstay of treatment until recently. These preparations are increasingly being replaced by transdermal patches, gels, and long-acting parenteral preparations. Testosterone patches and gels are ideally for elderly men. Treatment with the male hormone is relatively safe, if patients are selected appropriately and monitored carefully. The most important adverse effects are on the prostate. In this review, we briefly discuss the indications, contraindications, and benefits of testosterone treatment. Further, we list the adverse effects, advantages, and disadvantages of various testosterone preparations in elderly men.

    It is usually assumed that being gay or lesbian and being Christian is contradictory. The eight men who participated in this qualitative inquiry demonstrate otherwise. I investigated the ways in which these men integrated their gay and Christian identities meaningfully into their lives. From the interview data, I discerned and describe in this paper a variety of strategies that these men adopted in order to facilitate identity integration of seemingly mutually exclusive identities. In the bid for social and political equality with heterosexuals, gays and lesbians typically have not received support from Christians, at least not from politically active Christians, many of whom participate in explicitly antigay campaigns. Given such a contentious context, I discuss the personal and political implications of integrating gay and evangelical Christian identities.

  19. Hepatitis A transmitted by food.

    PubMed

    Fiore, Anthony E

    2004-03-01

    Hepatitis A is caused by hepatitis A virus (HAV). Transmission occurs by the fecal-oral route, either by direct contact with an HAV-infected person or by ingestion of HAV-contaminated food or water. Foodborne or waterborne hepatitis A outbreaks are relatively uncommon in the United States. However, food handlers with hepatitis A are frequently identified, and evaluation of the need for immunoprophylaxis and implementation of control measures are a considerable burden on public health resources. In addition, HAV-contaminated food may be the source of hepatitis A for an unknown proportion of persons whose source of infection is not identified.

    AIMS—To determine the effectiveness of a selective hospital based hepatitis B immunisation programme and the barriers to be overcome in obtaining a successful outcome.
METHODS—Retrospective case note review of 265 infants born over a five year period to hepatitis B carrier mothers at a university affiliated hospital in Hackney, London.
RESULTS—A total of 242 infants (91%) were fully vaccinated; 217 (82%) had serology; 31 required booster doses. Percentages failing to reach second, third vaccinations, and serology on schedule rose exponentially (7%, 18%, 33% respectively). Mobility was high (25%) and significantly affected outcome. A total of 95% Hackney resident babies were fully vaccinated compared with 78% non-residents. Uptake of routine immunisations was higher in Hackney residents than non-residents and greater in those who were eligible for hepatitis B vaccine. Name changes occurred in 35%. Translation requirements were high (85% for Turkish, Vietnamese, and Asian families). Requirements for specific postnatal counselling of mothers and hepatology referral fell significantly during the course of the study. Only seven of 22 babies born in 1995 in Tower Hamlets compared with 53 of 58 Hackney babies received a full vaccination course in non-hospital based primary care.
CONCLUSION—In inner city areas with high prevalence of hepatitis B carriage, mobility, and diverse ethnicity, a dedicated centralised immunisation service can be highly effective, provided that adequate support services (translation, counselling, and parental referral) are available.

  2. Customizable Digital Receivers for Radar

    NASA Technical Reports Server (NTRS)

    Moller, Delwyn; Heavey, Brandon; Sadowy, Gregory

    2008-01-01

    Compact, highly customizable digital receivers are being developed for the system described in 'Radar Interferometer for Topographic Mapping of Glaciers and Ice Sheets' (NPO-43962), NASA Tech Briefs, Vol. 31, No. 7 (August 2007), page 72. The receivers are required to operate in unison, sampling radar returns received by the antenna elements in a digital beam-forming (DBF) mode. The design of these receivers could also be adapted to commercial radar systems. At the time of reporting the information for this article, there were no commercially available digital receivers capable of satisfying all of the operational requirements and compact enough to be mounted directly on the antenna elements. A provided figure depicts the overall system of which the digital receivers are parts. Each digital receiver includes an analog-to-digital converter (ADC), a demultiplexer (DMUX), and a field-programmable gate array (FPGA). The ADC effects 10-bit band-pass sampling of input signals having frequencies up to 3.5 GHz. The input samples are demultiplexed at a user-selectable rate of 1:2 or 1:4, then buffered in part of the FPGA that functions as a first-in/first-out (FIFO) memory. Another part of the FPGA serves as a controller for the ADC, DMUX, and FIFO memory and as an interface between (1) the rest of the receiver and (2) a front-panel data port (FPDP) bus, which is an industry-standard parallel data bus that has a high data-rate capability and multichannel configuration suitable for DBF. Still other parts of the FPGA in each receiver perform signal-processing functions. The digital receivers can be configured to operate in a stand-alone mode, or in a multichannel mode as needed for DBF. The customizability of the receiver makes it applicable to a broad range of system architectures. The capability for operation of receivers in either a stand-alone or a DBF mode enables the use of the receivers in an unprecedentedly wide variety of radar systems.

    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

    Research indicates that chronic hepatitis C affects people's quality of life, but such reports are scarce about hepatitis B. This Australian study explored whether perceived stigma and satisfaction with received information and care were related to health-related quality of life in people with chronic hepatitis B or C. A questionnaire was constructed comprising demographic questions and existing scales to measure the variables. The 77 participants were recruited through various online channels. The median age was 48 years, 74% had hepatitis C, 60% were female, and 73% were Caucasian. Participants with Hepatitis B reported substantially less perceived stigma than those with Hepatitis C, but there was no significant difference between the two groups in health-related quality of life. Participants with Hepatitis C reported higher satisfaction with received information. The results highlight specific aspects to consider in the care of people with chronic hepatitis. For example, people with hepatitis B do not seem to enjoy better health-related quality of life despite lower perceived stigmatization. Therefore, these patients may require other improvements in service delivery such as the provision of more culturally appropriate information and education about chronic hepatitis B.

    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.

    1990-01-01

    In the last years the research on viral hepatitis let to better understand the biological, molecular, immunological and epidemiologic characteristics of the viruses that are responsible for hepatitis. The first studied virus was hepatitis B virus (HBv). The scientific attention is still, today, focused on that virus since new markers of infectivity and biological importance in early diagnosis and in disease evolution have been found. The most important result in the last years in the field of viral hepatitis has been, however, the identification of agents responsible for Non-A-Non-B hepatitis. Its epidemiology and clinical importance are discussed in the present paper. Virus C is the most important parenteral agent of NANB hepatitis. Its epidemiology in at risk populations and its role in post-transfusional and cryptogenetic hepatitis are here discussed. The research of new markers of HCV infection is today considered a main goal since the role of the only marker now available is still under discussion.

    Recent reports indicate that computed tomography (CT) after bolus injection of contrast material is diagnostically specific for hemangioma, replacing the need for angiography in a high percentage of patients. The authors report a unique hepatic hemangioma that showed early diffuse intense opacification by angiography and contrast-enhanced CT.

    The goal of antiviral therapy for patients with chronic hepatitis C virus (HCV) infection is to attain a sustained virologic response (SVR), which is defined as undetectable serum HCV-RNA levels at 6 months after the cessation of treatment. Major improvements in antiviral therapy for chronic hepatitis C have occurred in the past decade. The addition of ribavirin to interferon-alfa therapy and the introduction of pegylated interferon (PEG-IFN) have substantially improved SVR rates in patients with chronic hepatitis C. The optimization of HCV therapy with PEG-IFN and ribavirin continues to evolve. Studies are ongoing that use viral kinetics to tailor therapy to an individual's antiviral response and determine the ideal length of treatment to maximize the chance of SVR. Improved SVR can be achieved with new specific inhibitors that target the HCV NS3/4A protease and the NS5B polymerase. Several long-term follow-up studies have shown that SVR, when achieved, is associated with a very low risk of virologic relapse. Furthermore, antiviral therapy can reduce the morbidity and mortality rates associated with chronic hepatitis C by reducing fibrosis progression, the incidence of cirrhosis, and hepatocellular carcinoma.

    Prostate cancer is the most common visceral malignancy in men. As the tumor is testosterone dependent, a frequent treatment modality involves therapy with GnRH agonists (GnRH-a) resulting in hypogonadism. Because testosterone is essential for the maintenance of bone mass in men, we postulated that GnRH-a therapy would negatively impact skeletal integrity. We compared bone mineral density (BMD), biochemical markers of bone turnover, and body composition in 60 men with prostate cancer (19 men receiving GnRH-a therapy and 41 eugonadal men) and BMD in 197 community-living healthy controls of similar age. BMD was assessed by dual energy x-ray absorptiometry and ultrasound. Biochemical markers of bone turnover, included markers of bone resorption (urinary N-telopeptide) and bone formation markers (bone-specific alkaline phosphatase and osteocalcin). Body composition (total body fat and lean body mass) was assessed by dual energy x-ray absorptiometry. Significantly lower BMD was found at the lateral spine (0.69 +/- 0.17 vs. 0.83 +/- 0.20 g/cm(2); P < 0.01), total hip (0.94 +/- 0.14 vs. 1.05 +/- 0.16 g/cm(2); P < 0.05), and forearm (0.67 +/- 0.11 vs. 0.78 +/- 0.07 g/cm(2); P < 0.01) in men receiving GnRH-a compared with the eugonadal men with prostate cancer. Significant differences were also seen at the total body, finger, and calcaneus (all P < 0.01). BMD values in eugonadal men with prostate cancer and healthy controls were similar. Markers of bone resorption (urinary N-telopeptide) and bone formation (bone-specific alkaline phosphatase) were elevated in men receiving GnRH-a therapy compared with those in eugonadal men with prostate cancer. Men receiving GnRH-a also had a higher percent total body fat (29 +/- 5% vs. 25 +/- 5%; P < 0.01) and lower percent lean body weight (71 +/- 5% vs. 75 +/- 5%; P < 0.01) compared with eugonadal men with prostate cancer. In conclusion, men with prostate cancer receiving androgen deprivation therapy have a significant decrease in bone

    The aim of this study was to determine the factors affecting hepatitis B vaccine immunogenicity among nursing staff of Teaching Hospital, Jaffna. 152 nursing staffs were recruited from April to July 2013. Those who received three doses had 7.7% failure rate in developing protective immune response. Failure rates were 20% in those who received one dose and 10.6% in two doses. Following vaccination, participants who had chickenpox had a failure rate of 75% (n=13; p=0.02). Pregnancy significantly impaired protective immunity among those who received two doses (p=0.03). Three doses of hepatitis B vaccine may not be sufficient to protect the vaccinees. Therefore assessment of HBsAb titres is warranted after vaccination.

    The U.S. Navy Navigation Satellite System, NNSS, offers a unique worldwide facility for precise time synchronization. Space Applications Centre (SAC) developed a simple timing receiver. Using this timing receiver first the internal time consistency of NNSS was studied and then its performance to synchronize time was compared with that of National Time Standard. The methodology of data analysis, results, and various sources of error which affect the time transfer accuracy were studied and described. The main source of error was found to be the receiver delay which varies with signal strength. It is possible to apply that this delay correction empirically provided signal strength is recorded.

    Hepatitis E is an important public health problem in many countries. However, there is no definite conclusion about the zoonotic reservoir, transmission patterns and risk factors of hepatitis E in the human population. The aim of this study was to analyze the epidemiological and viral genotype characteristics of hepatitis E cases in northern China. Surveillance was conducted in two hospitals in Liaoning and Hebei province from July 2010 to June 2012. Out of a total of 116 diagnosed patients, 88 (75.9%) were male and 28 (24.1%) were female and most (73%) were in the age group 40-70 years. In both hospitals, cases were diagnosed more frequently in March than in other months. HEV RNA was amplified from 41 patients and characterized by nucleotide sequencing and phylogenetic analysis. Most of the isolates (37 strains, 90.3%) were genotype 4, including subgenotypes 4a, 4b, 4d, 4h, 4i and a new subgenotype. One subgenotype 3a strain was isolated from Baoding, Hebei province. Three genotype 1b strains were found from patients in Jinzhou, Liaoning province. Most of the genotype 4 strains and the genotype 3 strains were phylogenetically related to known swine isolates. In conclusion, the finding that HEV infects mostly middle-aged and elderly men and that the incidence spiked in March may reflect the zoonotic transmission characteristics of HEV infection. Pigs, but not rabbits, were the important reservoirs in this area, because genotype 4 HEV was found to be responsible for the majority hepatitis E cases. However, genotype 1 is still present in northern China. Also, the first isolation of genotype 3 HEV in this area indicates that alternative routes of HEV transmission might exist.

    The pharmacokinetics of grepafloxacin, a new broad spectrum fluoroquinolone antibiotic, were studied in 2 trials involving 14 healthy volunteers, 10 individuals with mild (Child-Pugh Class A) impairment of liver function, and 12 with moderate (Child-Pugh Class B or C) hepatic impairment. All participants received an oral dose of grepafloxacin 400 mg, daily for 7 days, and plasma and urine grepafloxacin concentrations were measured over 7 days. The pooled data from participants with impaired liver function showed that, compared with healthy individuals, peak plasma grepafloxacin concentrations, area under the plasma concentration-time curve and proportion of the dose excreted in the urine were increased. In addition, apparent total clearance was reduced in the presence of hepatic dysfunction. Peak concentrations were increased by 36% and 48% in individuals with Class A and B disease, respectively; the corresponding reductions in clearance were 33% and 55%, respectively. Child-Pugh scores and components of the scores showed no correlation with any pharmacokinetic variables. Based on these findings, we recommend a daily grepafloxacin dose of 400 mg in patients with mild hepatic impairment, irrespective of the severity of infection. Grepafloxacin should not be used in patients with moderate or severe liver disease.

    In spite of low endemic levels in France, hepatitis A and hepatitis B remains major concerns for public health. Seroprevalence of antibodies against hepatitis A (anti-HAV), declining below 15% in the 20 years-aged subjects, highlights an increasing susceptibility to hepatitis A. Later in the life, HAV infections become more serious and expansive. Control measures against hepatitis B have nearly stopped HBV spread linked to blood transfusions and mothers to infants transmission. Now, common risk factors are first sexual exposure, then injecting drug use, especially among young people. Vaccination is recognized as the most effective process for prevention. Recombinant hepatitis B vaccines have taken the place of plasma-derived vaccines. Although non responder individuals and escape mutants of HBV may hamper vaccinal coverage, hepatitis vaccines are highly immunogenic in immunocompetent people, allowing simplified schedules and reduced HBsAg dosages for children. Inactivated HAV vaccines now licensed prove to be highly immunogenic after only one injection. Hepatitis B vaccination targeted on high risk groups remains imperative but inadequate for reducing hepatitis B occurrence. A universal hepatitis B vaccination program in childhood and early adolescence would nearly stop the spread of HBV in the populations before ten years. Likewise, hepatitis A vaccination of travelers to endemic areas, all individuals exposed to contaminations from fecal sources, and food handlers, could reduce the spread of HAV in the community but would not completely prevent outbreaks of hepatitis A. Advantages of universal immunization of babies are not proved yet. Implementation of preventive strategies first needs a comprehensive surveillance of viral hepatitis in France.

    Purpose We conducted a phase I study of a 30-minute hepatic artery infusion of melphalan via a percutaneously placed catheter and hepatic venous hemofiltration using a double balloon catheter positioned in the retrohepatic inferior vena cava to shunt hepatic venous effluent through an activated charcoal filter and then to the systemic circulation. The purpose of the study was to demonstrate feasibility in an initial cohort and subsequently determine the maximum tolerated dose and dose-limiting toxicity of melphalan. Patients and Methods The initial cohort (n = 12) was treated with 2.0 mg/kg of melphalan before dose escalation to 3.5 mg/kg (n = 16). Total hepatic drug delivery, systemic levels, and percent filter efficiency were determined. Patients were assessed for hepatic and systemic toxicity and response. Results A total of 74 treatments were administered to 28 patients. Twelve patients with primary and metastatic hepatic tumors received 30 treatments (mean, 2.5 per patient) at an initial melphalan dose of 2.0 mg/kg. At 3.5 mg/kg, a dose-limiting toxicity (neutropenia and/or thrombocytopenia) was observed in two of six patients. Transient grade 3/4 hepatic and systemic toxicity was seen after 19% and 66% of treatments, respectively. An overall radiographic response rate of 30% was observed in treated patients. In the 10 patients with ocular melanoma, a 50% overall response rate was observed, including two complete responses. Conclusion Delivery of melphalan via this system is feasible, with limited, manageable toxicity and evidence of substantial antitumor activity; 3 mg/kg is the maximum safe tolerated dose of melphalan administered via this technique.

    To conduct and evaluate the impact of a theory-based health education intervention on awareness of prostate cancer and intention to screen among men in Western Jamaica and determine screening rates of men participating in the intervention at 6 months post-intervention. 454 men utilizing various clinics and hospitals in Western Jamaica completed an interviewer-administered pretest survey on general prostate cancer knowledge and intention to screen. Upon completing the pretest, participants observed a prostate cancer health education intervention and immediately completed a posttest survey. Statistically significant improvements in the percentage of correct responses between the pretest and posttest were evident (p < 0.05). Additionally, screening rates increased dramatically by 6 months post-intervention with over 33% of men receiving a prostate exam after participating in the educational intervention. The theory-based educational intervention increased participants' knowledge of prostate cancer, types of screening tests, frequency of screenings and risk factors and symptoms, and was effective in increasing screening rates among the men in Western Jamaica within 6 months post-intervention. This theory-based educational intervention may be replicated to promote awareness of prostate cancer and further increase screening rates in other areas of Jamaica and other developing countries.

    We assessed associations in substance use, psychosocial characteristics, and HIV-related sexual risk behaviors, comparing characteristics of Black men who only have sex with other men only (BMSMO; n = 839) to Black men who have sex with men and women (BMSMW; n = 590). The study analyzed baseline data from the HIV Prevention Trials Network Brothers Study (HPTN 061), a feasibility study of a multi-component intervention for Black MSM in six US cities. Bivariate analyses compared BMSMO to BMSMW along demographics, substance use, psychosocial characteristics, and HIV-related sexual risk behaviors. Logistic regression models then assessed multivariable associations between being BMSMW and the odds of engaging in HIV-related sexual risk behaviors. Adjusted analyses revealed that BMSMW remained more likely to have unprotected anal intercourse while under the influence of alcohol (AOR: 1.45; 95 % CI:1.11-1.90) and were more likely to receive money/drugs for sex (AOR: 2.11; 95 % CI:1.48-3.03), compared to BMSMO. Substance use is an important factor to be considered when developing risk-reduction interventions for BMSMW. Structural interventions that address factors that may contribute to exchange sex among these men are also warranted.

    Multiple cutaneous infantile hemangiomas have been associated with hepatic hemangiomas. Screening of infants with five or more cutaneous infantile hemangiomas with abdominal ultrasound is often recommended. The aim of this study was to determine the frequency with which hepatic hemangiomas occur in infants with five or more cutaneous infantile hemangiomas compared to those with one to four cutaneous infantile hemangiomas and to characterize the clinical features of these hepatic hemangiomas. A multicenter prospective study of children with cutaneous infantile hemangiomas was conducted at pediatric dermatology clinics at Hemangioma Investigator Groups sites in the United States, Canada, and Spain between October 2005 and December 2008. Data were collected, and abdominal ultrasonography was performed on infants younger than 6 months old with five or more cutaneous infantile hemangiomas and those with one to four cutaneous infantile hemangiomas. Twenty-four (16%) of the 151 infants with five or more cutaneous infantile hemangiomas had hepatic hemangiomas identified on abdominal ultrasound, versus none of the infants with fewer than five (p = 0.003). Two of the 24 infants with hepatic hemangiomas received treatment specifically for their hepatic hemangiomas. Infants with five or more cutaneous infantile hemangiomas have a statistically significantly greater frequency of hepatic hemangiomas than those with fewer than 5. These findings support the recommendation of five or more cutaneous infantile hemangiomas as a threshold for screening infants younger than 6 months old for hepatic hemangiomas but also demonstrate that the large majority of these infants with hepatic hemangiomas do not require treatment.

    Sedgwick, Leigh M.

    1991-01-01

    A full-size, solar dynamic heat receiver was designed to meet the requirements specified for electrical power modules on the U.S. Space Station, Freedom. The heat receiver supplies thermal energy to power a heat engine in a closed Brayton cycle using a mixture of helium-xenon gas as the working fluid. The electrical power output of the engine, 25 kW, requires a 100 kW thermal input throughout a 90 minute orbit, including when the spacecraft is eclipsed for up to 36 minutes from the sun. The heat receiver employs an integral thermal energy storage system utilizing the latent heat available through the phase change of a high-temperature salt mixture. A near eutectic mixture of lithium fluoride and calcium difluoride is used as the phase change material. The salt is contained within a felt metal matrix which enhances heat transfer and controls the salt void distribution during solidification. Fabrication of the receiver is complete and it was delivered to NASA for verification testing in a simulated low-Earth-orbit environment. This document reviews the receiver design and describes its fabrication history. The major elements required to operate the receiver during testing are also described.

    Hepatitis A, B, and C are important viral hepatitis infections in the Thai population. Hepatitis B vaccination was included in the Thai Expanded Program on Immunization (EPI) 10 years ago. In addition, the seroprevalence of hepatitis A has significantly changed in the last two decades. This study was done to evaluate current risk groups for hepatitis A and B infections and identify the magnitude of hepatitis C infection in the general population of Bangkok and six provinces in the Central Region of Thailand, during the period October 2000 to January 2002. This study revealed that the prevalence of anti-HAV in people younger than 25 years was low but very high in people older than 25 years. The prevalence of anti-HAV was 1.95% in Bangkok and 12.7% in other provinces in people younger than 25 years (p<0.001) while 90.9% in Bangkok and 88.2% in other provinces among people older than 25 years. Therefore, people who are older than 25 years should have a blood test for anti-HAV before getting a hepatitis A vaccination. Approximately 80% of people who are not covered by hepatitis B vaccination from EPI are at risk of hepatitis B infection and its complications. This group of people should receive hepatitis B vaccination. For hepatitis C, the prevalence is lower than 2% across age groups and areas. Therefore, current good primary prevention via blood donor screening and health education must be maintained.

    Hepatic resection is the treatment of choice for primary and secondary hepatic tumors but only 15-25% of patients with hepatic colorectal metastases are eligible for a curative hepatic resection. Cryosurgical ablation (CSA) is employed when curative resection of metastases cannot be obtained. Sixty-four patients (35 males, 29 females, mean age 58.8 years, range 30-79 years) with hepatic colorectal metastases underwent CSA, under laparoscopic control (15 cases) or with open surgery (49 cases), with subsequent close follow-up. Intraoperative bleeding occurred in 32 out of 49 patients in the open group and only in 2 patients in the laparoscopic group. Minor morbidity that resolved with conservative treatment was 54.8% in the open group and 53.3% in the laparoscopic group. Major morbidity occurred in 11 cases (26.2%) in the open group and in 1 case (6.7%) in the laparoscopic group. Mortality occurred in two patients, both in the open group, from renal insufficiency in one case and from liver failure in the other case. Mean hospital stay was 16.7 days in the open group (range 8-72 days) and 10.6 days in the laparoscopic group (range 3-18 days). No patient was lost to follow-up. At a mean follow-up of 87.1 months (range 52.2-125.2 months), selected patients undergoing laparoscopic CSA had an overall survival rate of 66.7% (10 patients), with 30% of patients (3) who are disease-free. Median survival was 94.2 months. Recurrence was observed in seven patients. None of the intrahepatic recurrences was at the cryoablation site. In the open group, median survival was 22.9 months with a survival rate of 30.9% (13 patients) at a mean follow-up of 39.3 months (range 1.9-124.5 months); 9 patients (19.1%) are disease-free. In selected patients, laparoscopic CSA is associated with survival rates which are similar to those after hepatic resection. In patients with a larger tumor burden, CSA offers a curative treatment to patients with otherwise a dismal prognosis and it improves

    Objective: Cancer patients have reported that information plays a significant role in their capacity to cope with cancer and manage the consequences of treatment. This study was undertaken to identify the importance older adults receiving cancer treatment assign to selected types of cancer-related information, their satisfaction with the cancer-related information they received, and the barriers to effective information provision for this age group. Methods: This study was conducted in two phases with separate samples. Six hundred and eighty-four older cancer patients receiving treatment completed a standardized survey and 39 completed a semi-structured interview to gather perspectives about cancer-related information. Data were analyzed for 65-79 years and 80+ year groups. Results: Information topics about their medical condition, treatment options, and side effects of treatment were rated as most important by the older cancer patients. Women assigned a higher importance ratings than men to information overall (t = 4.8, P < 0.01). Although participants were generally satisfied with the information, they received many described challenges they experienced in communicating with health care professionals because of the medical language and fast pace of speaking used by the professionals. Conclusions: The older cancer patients in this study endorsed the same topics of cancer-related information as most important as has been reported in studies for other age groups. However, this older group recommended that, during their interactions with older individuals, health care professionals use fewer medical words, speak at a slower pace, and provide written information in addition to the actual conversation.

    Persistence of immune response was assessed in adults aged >40 years (N = 596) following primary vaccination with combined hepatitis A/B vaccine or concomitant monovalent hepatitis A and B vaccines. Anti-hepatitis A virus antibody responses persisted for at least 4 years regardless of the vaccine used, with anti-hepatitis B surface antibody responses higher and more sustained in subjects who received the combined hepatitis A/B vaccine. Response rates to an additional dose of the same vaccine(s) used for priming were high.

    Background Norway is classified as a low prevalence country for hepatitis B virus infection. Vaccination is only recommended for risk groups (intravenous drug users (IDUs), Men who have Sex with Men (MSM), immigrants and contacts of known carriers). We describe the epidemiology of reported cases of hepatitis B in Norway, during the years 1992-2009 in order to assess the validity of current risk groups and recommend preventive measures. Methods We used case based data from the national surveillance system on acute and chronic hepatitis B. The Norwegian Statistics Bureau provided population and migration data and the Norwegian Institute for Alcohol and Drug Research the estimated number of active IDUs between 2002-2007. Incidence rates (IR) and incidence rate ratios (IRR) for acute hepatitis B and notification rates (NR) and notification rate ratios (NRR) for chronic hepatitis B with 95% confidence intervals were calculated. Results The annual IR of acute hepatitis B ranged from 0.7/100,000 (1992) to 10.6/100,000 (1999). Transmission occurred mainly among IDUs (64%) or through sexual contact (24%). The risk of acquiring acute hepatitis B was highest in people aged 20-29 (IRR = 6.6 [3.3-13.3]), and in males (IRR = 2.4 [1.7-3.3]). We observed two peaks of newly reported chronic hepatitis B cases in 2003 and 2009 (NR = 17.6/100,000 and 17.4/100,000, respectively). Chronic hepatitis B was more likely to be diagnosed among immigrants than among Norwegians (NRR = 93 [71.9-120.6]), and among those 20-29 compared to those 50-59 (NRR = 5.2 [3.5-7.9]). Conclusions IDUs remain the largest risk group for acute hepatitis B. The observed peaks of chronic hepatitis B are related to increased immigration from high endemic countries and screening and vaccination of these groups is important to prevent further spread of infection. Universal screening of pregnant women should be introduced. A universal vaccination strategy should be considered, given the high cost of reaching the

    Hepatitis C viral infection is accompanied by various serum alterations that could explain its molecular impact on hepatic structure and metabolic homeostasis. Recently it has been shown that adipocytokines play a pivotal role in development of hepatic steato-fibrosis, different studies giving a support of the hypothesis that the balance of adipocytokine expression is a key regulator for the progression of hepatic steatosis and fibrosis. The association between insulin resistance and hepatitis C virus genotypes and liver fibrosis stage foreshadowed that virus-induced insulin resistance may be a mechanism for fibrogenesis in chronic hepatitis C virus infection. The main importance of adipocytokine profile detection consists in the prediction of steatosis induction that has clinical relevance, being associated with advanced fibrosis and hyporesponsiveness to antiviral therapy.

    Background Hepatic angiosarcoma (HAS) is a rare type of liver cancer that is often fatal, and arsenic and vinyl chloride monomer (VCM) are two major causal agents. Whereas Taiwan is an endemic area of liver cancer, epidemiologic data on HAS are limited. We reviewed the cases observed at a teaching hospital to evaluate the roles of VCM, arsenic, and viral hepatitis in the occurrence of HAS. Methods We reviewed the medical records of patients with pathological proof of HAS from January 2000 to August 2010 at a teaching hospital which is adjacent to the major VCM processing area in Taiwan and nearby an endemic area of arsenic exposure from drinking water. We also conducted a literature review and included all patients of HAS reported in Taiwan. Results Six male and three female cases aged from 56 to 83 years (64.6 ± 8.2 years) were identified at the hospital. The differences in clinical features between men and women were not statistically significant. None of them had exposure to VCM or arsenic in drinking water. Two had evidence of hepatitis C infection, but none had evidence of hepatitis B infection. Five male and four female cases aged 30 to 82 years (58.6 ± 15.5 years) were identified in the literature, including two with arsenic exposure and one with chronic hepatitis B infection. Conclusions HAS is rare in Taiwan, and we found no evidence supporting a major role of VCM, arsenic in drinking water, or viral hepatitis in its occurrence. PMID:22200164

    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.

    OBJECTIVES: This study assessed seroprevalence rates of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) among individuals with severe mental illness. METHODS: Participants (n = 931) were patients undergoing inpatient or outpatient treatment in Connecticut, Maryland, New Hampshire, or North Carolina. RESULTS: The prevalence of HIV infection in this sample (3.1%) was approximately 8 times the estimated US population rate but lower than rates reported in previous studies of people with severe mental illness. Prevalence rates of HBV (23.4%) and HCV (19.6%) were approximately 5 and 11 times the overall estimated population rates for these infections, respectively. CONCLUSIONS: Elevated rates of HIV, HBV, and HCV were found. Of particular concern are the high rates of HCV infection, which are frequently undetected. Individuals with HCV infection commonly fail to receive appropriate treatment to limit liver damage and unknowingly may be a source of infection to others. PMID:11189820
