    Vietnamese American men are over 10 times more likely to be diagnosed with liver cancer than their white counterparts. This health disparity is attributable to high rates of hepatitis B virus (HBV) infection. Our study objective was to examine factors associated with HBV testing among Vietnamese men. A population-based survey was conducted in Seattle. The questionnaire content was guided by an earlier qualitative study and the Health Behavior Framework. The survey was completed by 345 men (response rate: 80%). About one-third (34%) of the respondents reported they had not been tested for HBV. The following factors were associated (P < 0.01) with previous testing in bivariate comparisons: having a regular source of care and regular provider; knowing that HBV can be spread during childbirth; believing HBV can cause liver cancer; and doctor(s) had recommended testing as well as had asked doctor(s) for testing. Three variables were independently associated with HBV testing in a logistic regression model: regular source of care (OR = 4.5; 95% CI = 2.6–7.9), physician recommendation (OR = 2.3, 95% CI = 1.3–4.0), and knowing HBV can be spread during childbirth (OR = 2.1; 95% CI = 1.2–3.9). Low levels of HBV testing remain a public health problem in some Vietnamese American sub-groups. Health education about HBV transmission may stimulate patients to seek testing. Intervention programs should specifically target Vietnamese men without a regular source of health care and physicians who serve Vietnamese communities. PMID:15225896

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

    OBJECTIVES: A hepatitis A outbreak among men who have sex with men (MSM) led to a publicly funded vaccination campaign. We evaluated the MSM community's response. METHODS: A cohort of MSM from 5 community sites was surveyed. RESULTS: Thirty-four (19%) of 178 potential vaccine candidates received the vaccine during the campaign. We found a linear relation between the number of exposures to campaign information and the likelihood of vaccination (P < .001). Vaccination was independently associated with awareness of the outbreak and the vaccine, having had sexual relations with men for 12 years or longer, having recently consulted a physician, and routinely reading a local gay newspaper. CONCLUSIONS: The difficult task of vaccinating MSM can be aided by repetitive promotional messages, especially via the gay media. PMID:11111274

    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.

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

    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.

    Background. There is an international epidemic of hepatitis C virus (HCV) infection among human immunodeficiency virus (HIV)–infected men who have sex with men. Sustained virologic response (SVR) rates with pegylated interferon and ribavirin treatment are higher in these men during acute HCV than during chronic HCV, but treatment is still lengthy and SVR rates are suboptimal. Methods. We performed a pilot study of combination therapy with telaprevir, pegylated interferon, and ribavirin in acute genotype 1 HCV infection in HIV-infected men. Men who were treated prior to the availability of, or ineligible for, telaprevir were the comparator group. The primary endpoint was SVR12, defined as an HCV viral load <5 IU/mL at least 12 weeks after completing treatment. Results. In the telaprevir group, 84% (16/19) of men achieved SVR12 vs 63% (30/48) in the comparator group. Among men with SVR, median time to undetectable viral load was week 2 in the telaprevir group vs week 4 in the comparator group, and 94% vs 53% had undetectable viral loads at week 4. Most patients (81%) who achieved SVR in the telaprevir group received ≤12 weeks of treatment and there were no relapses after treatment. The overall safety profile was similar to that known for telaprevir-based regimens. Conclusions. Incorporating telaprevir into treatment of acute genotype 1 HCV in HIV-infected men halved the treatment duration and increased the SVR rate. Larger studies should be done to confirm these findings. Clinicians should be alert to detect acute HCV infection of HIV-infected men to take advantage of this effective therapy and decrease further transmission in this epidemic. PMID:24336914

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

    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.

    Background. The probability of spontaneous hepatitis C virus (HCV) clearance ranges from 11% to 49%. Our previous cross-sectional study suggests that mode of acquisition explains some of this heterogeneity. We performed this prospective study to determine factors associated with spontaneous HCV clearance among men who have sex with men (MSM). Methods. A mixture-cure model was used to evaluate the probability of spontaneous HCV clearance among 101 MSM in the Multicenter AIDS Cohort Study with acute HCV infection between 1984 and 2012. Results. Spontaneous HCV clearance occurred in 46% of MSM (49% in non-injection drug users [IDUs] and 23% in IDUs). In the multivariable analysis, age <30 years (clearance ratio [CR] = 2.43; 95% confidence interval [CI], 1.53–3.87) and being human immunodeficiency virus (HIV) uninfected (CR = 2.97; 95% CI, 1.98–4.46) were independently associated with spontaneous clearance. Among men aged ≥30 years, being HIV uninfected, not having unprotected anal intercourse, older age, and being on highly active antiretroviral therapy were independently associated with higher clearance. The interferon lambda rs12979860 single nucleotide polymorphism (SNP) was not associated with spontaneous clearance among the 88 MSM who were not active IDUs (CR = 0.74; 95% CI, .46–1.21 for CC vs CT/TT genotype). Conclusions. The high probability of spontaneous HCV clearance together with the lack of an association between the rs12979860 SNP and spontaneous clearance among MSM who do not use injection drugs suggests that the immune mechanisms involved with a successful response to acute HCV differ by mode of virus acquisition. Understanding potential mechanistic differences could be important for HCV vaccine development. PMID:26175521

    Introduction Hepatitis C virus (HCV) is the major cause of liver disease in hemophilia. Few data exist on the proportion with liver fibrosis in this group after long-term HCV and HIV co-infection. Aim We conducted a cross-sectional multi-center study to determine impact of HIV on the prevalence and risk factors for fibrosis in hemophilic men with chronic hepatitis C. Methods Biopsies were independently scored by Ishak, Metavir, and Knodell systems. Variables were tested for associations with fibrosis by logistic regression and receiver operating curves (ROC). Results Of 220 biopsied HCV(+) men, 23.6% had Metavir ≥F3 fibrosis, with higher mean Metavir fibrosis scores among HIV/HCV co-infected than HCV mono-infected, 1.6 vs. 1.3 (p=0.044). Variables significantly associated with fibrosis included AST, ALT, APRI score (AST/ULN×100/platelet ×109/L), alpha-fetoprotein (all p<0.0001), platelets (p=0.0003), and ferritin (p=0.0008). In multiple logistic regression of serum markers, alpha-fetoprotein, APRI, and ALT were significantly associated with ≥ F3 fibrosis, AUROC=0.77 (95%CI 0.69, 0.86). Alpha-fetoprotein, APRI, and ferritin were significant in HIV(−), (AUROC 0.82 (95%CI 0.72, 0.92), and alpha-fetoprotein and platelets in HIV(+) (AUROC=0.77 (95%CI 0.65, 0.88). In a multivariable model of demographic and clinical variables, transformed (natural logarithm) of alpha-fetoprotein (p=0.0003), age (p=0.006), and HCV treatment (p=0.027) were significantly associated with fibrosis. Conclusion Nearly one-fourth of hemophilic men have Metavir ≥ 3 fibrosis. The odds for developing fibrosis are increased in those with elevated alpha-fetoprotein, increasing age, and past HCV treatment. PMID:20722744

    Background. Sexually transmitted hepatitis C virus (HCV) infection is an emerging epidemic among human immunodeficiency virus (HIV)–infected men who have sex with men (MSM). HCV may be underrecognized in this population, historically thought to be at low risk. Methods. We determined the prevalence and incidence of HCV among HIV-infected men at Fenway Health between 1997 and 2009. We describe characteristics associated with HCV. Results. Of 1171 HIV-infected men, of whom 96% identify as MSM, 1068 (91%) were screened for HCV and 64 (6%) had a positive HCV antibody (Ab) result at initial screening. Among the 995 men whose initial HCV Ab result was negative, 62% received no further HCV Ab testing. Among the 377 men who had ≥1 additional HCV Ab test, 23 (6%) seroconverted over 1408 person-years, for an annualized incidence of 1.63 per 100 person-years (95% confidence interval, .97–2.30). Among the 87 HIV-infected MSM diagnosed with prevalent or incident HCV, 33% reported history of injection drug use, 46% noninjection drug use (NIDU), and 70% sexually transmitted infections (STIs). Sixty-four (74%) of HCV-infected MSM developed chronic HCV; 22 (34%) initiated HCV treatment and 13 (59%) of treated persons achieved a sustained virologic response (SVR). Conclusions. Prevalent and incident HCV, primarily acquired through nonparenteral means, was common in this HIV-infected population despite engagement in care. STIs and NIDU were common among HIV/HCV-coinfected MSM. SVR rates were high among those who underwent HCV treatment. All sexually active and/or substance-using HIV-infected MSM should receive routine and repeated HCV screening to allow for early diagnosis and treatment of HCV. PMID:23386630

    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. PMID:20595501

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. PMID:20595501

    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

    For advanced and metastatic prostate cancer, androgen deprivation therapy (adt) is the mainstay of treatment. Awareness of the potential bone-health complications consequent to adt use is increasing. Many studies have shown that prolonged adt leads to significant bone loss and increased fracture risk that negatively affect quality of life. Clinical practice guidelines for preserving bone health in men with prostate cancer on adt vary across Canada. This paper reviews recent studies on bone health in men with prostate cancer receiving adt and the current evidence regarding bone-health monitoring and management in reference to Canadian provincial guidelines. Based on this narrative review, we provide general bone-health management recommendations for men with prostate cancer receiving adt.

    Reactivation of hepatitis B virus (HBV) and de novo HBV hepatitis in patients with rheumatic diseases given intensive and long-term immunosuppressive therapy with or without biological disease-modifying antirheumatic drugs is of great concern, especially in regions where the virus is endemic, including Japan. To ascertain a better benefit-risk balance for immunosuppressive therapy for patients with rheumatic diseases, the Japan College of Rheumatology developed this proposal. All patients with rheumatic diseases commencing immunosuppressive therapy should be screened for hepatitis B surface antigen (HBsAg); those who are negative for HBsAg should be screened for hepatitis B core antibody (HBcAb) and hepatitis B surface antibody (HBsAb) as well. HBV carriers and serum HBV DNA positive patients with resolved infection should receive nucleoside analog as soon as possible, prior to commencing immunosuppressive therapy. For serum HBV DNA negative patients with resolved infection, careful monthly monitoring using serum levels of aspartate and alanine aminotransferases and HBV DNA is recommended during and at least 12 months after withdrawal of immunosuppressive therapy. If serum HBV DNA becomes positive, patients should receive nucleoside analog treatment as soon as possible, while ongoing immunosuppressive therapy should be continued to avoid severe or fulminant hepatitis development. To facilitate proper management of patients with HBV infection, collaboration between rheumatologists and hepatologists is strongly encouraged.

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

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

    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

    The great majority of patients with chronic viral hepatitis C are treated with pegylated interferon-ribavirin therapy. The aim of this study was to demonstrate that these patients were able to have some form of physical exercise, and that this activity can lead to an improvement in their quality-of-life. Twelve volunteer patients with hepatitis C, who were either sedentary or had become sedentary and who had been treated by combination therapy for the past few weeks, were recruited at hepatology clinics in the Midi-Pyrénées region of France early in 2006. All patients attended a sports medicine consultation for an initial evaluation: maximal aerobic power and maximal oxygen consumption tests, maximum heart rate (MHR), search for contraindications for participation in the proposed program of physical exercise. The patients were given a heart rate monitor so they could measure their heart rate during physical exercise and check that they exercised under safe conditions and remained within the so-called "endurance" zone. The patients came to a sports facility daily for 5 days for the exercise program. The activities were divided into four sessions each day: an individual physical exercise selected by the patient, team physical exercise, recreational physical exercise, lectures on the different types of hepatitis and their treatment, on nutrition and on sports medicine assessments. Data on hepatitis, results of the cardiorespiratory examination and personal history and record of past physical activity were collected for each patient. Quality-of-life (SF36) was assessed at enrollment in the study and one month after the training sessions. At the initial sports medicine consultation, all patients reached their MHR and were found capable of participating in the proposed physical exercise program. One enrolled patient was excluded from the analysis because of the presence of sinusitis on arrival. Seven men and four women, mean age of 46 years completed the full course of

    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.

    condition (P = 0.019). No risk factors associated with the development of HBV reactivation could be identified. Serial monitoring of HBV DNA, in addition to liver function, increases the sensitivity of diagnosing of HBV reactivation, and helps explain some cases that would otherwise be labeled as "cryptogenic hepatitis," for which concomitant HBV DNA measured at the time of hepatitis was undetectable. The present study highlights the importance of monitoring HBsAg-seropositive patients who are receiving chemotherapy for common solid tumors such as breast cancer. PMID:12794717

    Context and Objective: In most populations a greater proportion of men have hepatic steatosis than women. Sex-specific differences in hepatic dietary fatty acid (FA) metabolism have not been well characterized. We compared fasting and postprandial hepatic FA synthesis (de novo lipogenesis [DNL]) and oxidation in men and women. Participants and Methods: Fasting and postprandial hepatic FA metabolism was studied in 22 healthy men (n = 11) and women with similar age, body mass index, and liver fat content using metabolic substrates labeled with stable-isotope tracers (2H2O and [U13C]palmitate). Dietary FA oxidation was assessed by appearance of 13C into plasma 3-hydroxybutyrate and breath CO2 as markers of liver and whole-body FA oxidation, respectively. Results: Despite similar liver fat content, fasting and postprandial plasma triacylglycerol (TG) concentrations were significantly (P < .05) higher in men compared with women. The appearance of 13C from dietary FA into plasma 3-hydroxybutyrate and breath CO2 was greater (P < .05) in women compared with men. Although the contribution of DNL into very low-density lipoprotein (VLDL)-TG was similar (∼10%) in the fasting state, there was a divergence in pattern over the course of the study, with men maintaining a higher contribution of DNL to VLDL-TG than women (P = .006 time x sex interaction). Conclusions: The combination of lower dietary FA oxidation and a prolonged increase in DNL observed in men may represent partitioning of FA into esterification and storage pathways within the liver, leading to greater VLDL-TG production, and predispose to the sex difference in hepatic steatosis.

    2013-01-01

    Background Liver cancer is the second most-frequent cause of cancer death in Korea. Hepatitis B virus (HBV) infection is a major cause of liver cancer, and this disease is effectively prevented by HBV vaccination. This study was conducted to investigate factors associated with the lack of HBV vaccine uptake in the general adult male population in Korea. Methods Data of men who participated in a nationwide cross-sectional interview survey were analyzed. A total of 2,174 men 40 years of age and older were interviewed between 2006 and 2008. None of the participants was infected with HBV or was experiencing sequelae of an HBV infection. Results Only half (50.4%) of the men received one or more dose of the three-dose series of HBV vaccinations, and 32.5% received all three doses. Compared with men who had completed the vaccination regimen, non-vaccinated men were more likely to lack supplemental medical insurance for cancer (odds ratio = 0.66, 95% confidence interval: 0.52–0.84), have lower incomes (p-trend = 0.010), and be less educated (p-trend = 0.021). Lower education was also more prevalent in the non-vaccinated group compared with the incompletely vaccinated group. Those who had completed the vaccination regimen were likely to be more educated than those in the incompletely vaccinated group (p-trend = 0.044). The most commonly cited reason for not obtaining the HBV vaccine was lack of knowledge regarding the need for the vaccination. The number of men who cited this reason decreased as a function of education. Conclusions It is important to develop strategic interventions targeted at less-educated men to increase uptake of a complete three-dose series of HBV vaccinations as a primary approach to preventing liver cancer.

    Background There is a decrease in vaccine-specific antibody to certain vaccine-preventable diseases in children after chemotherapy, but the frequency of non-immune patients is not clear. In the present case-control study, was taken under investigation protection level to Hepatitis B infection in children 6 months after completing chemotherapy. Materials and Methods In this study 68 patients with cancer and 68 healthy children were enrolled. Patients were 1.5 -12 years old with completed standard chemotherapy at least for 6 months. All the patients and healthy children were negative for HBsAg and HBeAg and had received Hepatitis B vaccination. IgG antibody concentrations against Hepatitis B Virus (HBV) were determined in the patients receiving chemotrapy and healthy subjects serum by ELISA method. IgG antibody titer > 10 mIU/ml was considered as baseline protective titer for preventing HBV infection. Results Anti-HBs antibody titer in 19.12% of patients was less than 10 mIU/ml and 11.76% of the patients had borderline antibody titer (10-20 mIU/ml). In healthy subjects, 2.94% and 5.88% had antibody titer < 10 mIU/ml and 10-20 mIU/ml, respectively. According to statistical analysis, frequency of non immune subjects in children with cancer was significantly higher than those in healthy children (P-value=0.024). Conclusion HBV vaccination post-intensive chemotherapy in the children with cancer is strongly recommended. PMID:24575253

    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

    Background. We used a Monte Carlo computer simulation to estimate the effectiveness and cost-effectiveness of screening for acute hepatitis C virus (HCV) infection in human immunodeficiency virus (HIV)–infected men who have sex with men. Methods. One-time screening for prevalent HCV infection was performed at the time of enrollment in care, followed by either symptom-based screening, screening with liver function tests (LFTs), HCV antibody (Ab) screening, or HCV RNA screening in various combinations and intervals. We considered both treatment with pegylated interferon and ribavirin (PEG/RBV) alone and with an HCV protease inhibitor. Outcome measures were life expectancy, quality-adjusted life expectancy, direct medical costs, and cost-effectiveness, assuming a societal willingness to pay $100 000 per quality-adjusted life-year (QALY) gained. Results. All strategies increased life expectancy (from 0.49 to 0.94 life-months), quality-adjusted life expectancy (from 0.47 to 1.00 quality-adjusted life-months), and costs (from $1900 to $7600), compared with symptom-based screening. The incremental cost-effectiveness ratio of screening with 6-month LFTs and a 12-month HCV Ab test, compared with symptom-based screening, was $43 700/QALY (for PEG/RBV alone) and $57 800/QALY (for PEG/RBV plus HCV protease inhibitor). The incremental cost-effectiveness ratio of screening with 3-month LFTs, compared with 6-month LFTs plus a 12-month HCV Ab test, was $129 700/QALY (for PEG/RBV alone) and $229 900/QALY (for PEG/RBV plus HCV protease inhibitor). With HCV protease inhibitor–based therapy, screening with 6-month LFTs and a 12-month HCV Ab test was the optimal strategy when the HCV infection incidence was ≤1.25 cases/100 person-years. The 3-month LFT strategy was optimal when the incidence was >1.25 cases/100 person-years. Conclusions. Screening for acute HCV infection in HIV-infected MSM prolongs life expectancy and is cost-effective. Depending on incidence

    Background/Aims This study aimed to clarify the effect of obesity on the development of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients receiving antiviral treatment. Methods This study applied a retrospective analysis to a historical cohort in Bundang Jesaeng Hospital. In total, 102 CHB patients were treated with entecavir as an initial treatment for CHB and checked for obesity using a body composition analyzer. Hepatic steatosis was measured semiquantitatively using Hamaguchi’s scoring system in ultrasonography. Risk factors for the development of HCC were analyzed, including obesity-related factors (body mass index [BMI], waist circumference [WC], waist-to-hip ratio [WHR], visceral fat area [VFA], and hepatic steatosis). Results The median follow-up duration of the patients was 45.2 months (interquartile range: 36.0-58.3 months). The cumulative incidence rates of HCC at 1 year, 3 years, and 5 years were 0%, 5.3%, and 9.0%, respectively. Univariable analysis revealed that the risk factors for HCC development were a platelet count of <120,000 /mm2 (hazard ratio [HR]=5.21, P=0.031), HBeAg negativity (HR=5.61, P=0.039), and liver cirrhosis (HR=10.26, P=0.031). Multivariable analysis showed that the significant risk factor for HCC development was liver cirrhosis (HR=9.07, P=0.042). However, none of the obesity-related risk factors were significantly associated with HCC: BMI ≥25 kg/m2 (HR=0.90, P=0.894), WC ≥90 cm (HR=1.10, P=0.912), WHR ≥0.9 (HR=1.94, P=0.386), VFA ≥100 cm2 (HR=1.69, P=0.495), and hepatic steatosis (HR=0.57, P=0.602). Conclusion HCC development is associated with liver cirrhosis but not obesity-related factors in CHB patients receiving entecavir. PMID:27729627

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

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

    Background. We and others have shown that primary hepatitis C (HCV) infection in men infected with human immunodeficiency virus (HIV) causes early-onset liver fibrosis; however, little is known about the long-term natural history of the liver disease in these HIV-infected men. Methods. We followed a cohort of HIV-infected men with primary HCV infection in New York City. Results. Four men who were not cured after their primary HCV infection developed decompensated cirrhosis within 17 months to 6 years after primary HCV infection. Three died within 8 years of primary HCV infection, and 1 survived after liver transplant done 2 years after primary HCV infection. Three of the 4 men had AIDS at the time of primary HCV infection, and the most rapid progression occurred in the 2 men with the lowest CD4 counts at the time of HCV infection. Liver histopathology was most consistent with HCV-induced damage even though some had exposures to other potential hepatotoxins. Conclusions. Primary HCV infection resulted in decompensated cirrhosis and death within 2–8 years in 4 HIV-infected men. The rapid onset of fibrosis due to primary HCV infection in HIV-infected men cannot therefore be considered benign. The rate of continued progression to liver failure may be proportional to the degree of underlying immunocompromise caused by HIV infection. More research is needed to better define the mechanisms behind accelerated liver damage. PMID:23264364

    Limited data on HIV prevalence and related risks among men who have sex with men (MSM) exist in the Republic of Moldova. In Chisinau and Balti, 188 and 209, respectively, men who reported having anal or oral sex in the last six months with another man, aged ≥16 years were recruited into a study in 2010 using respondent-driven sampling methods. MSM reported having multiple male and female partners and inconsistent condom use. In Chisinau, 2% of MSM were HIV seropositive, 3.7% had antibodies to hepatitis C (HCV), 5.7% had antibodies to hepatitis B (HBV) and 12.1% had syphilis. In Balti, less than 1% of MSM were HIV seropositive, 1.2% had antibodies to HCV, 3.2% had antibodies to HBV and only 0.5% had syphilis. MSM who used a condom at last anal sex with a man were less likely to reside in Chisinau, to have casual sex partners and to have had an HIV test in the last year and were more likely to know where to get an HIV test. Although HIV prevalence was low, MSM practice a number of risky sexual behaviours that may heighten the risk of further HIV transmission in this population and to the wider population.

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

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

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

    Prostate cancer is the leading cancer diagnosis and second leading cause of cancer-related mortality for men in the United States. Due to the increased prevalence of prostate cancer in men older than 50 years, men at risk for prostate cancer represent the same population of men who are at greatest risk for metabolic syndrome, diabetes mellitus, and coronary artery disease (CAD). In addition to risk factors for CAD that are applicable to the general population, men with prostate cancer can be at increased risk for CAD due to long-term androgen deprivation therapy (ADT) administered as treatment for prostate cancer. Men undergo ADT by medical (drug therapy) or surgical (castration) means. Luteinizing hormone-releasing hormone (LHRH) agonists are the primary drug therapies used for ADT. Commercially available LHRH agonists are goserelin, histrelin, leuprolide, and triptorelin. Body composition changes, hyperlipidemia, insulin resistance, metabolic syndrome, and acute coronary syndrome are all reported adverse effects of ADT, which are consequences of reduced levels of circulating testosterone. Metabolic and body composition changes associated with ADT arise within months of beginning medical ADT and persist after discontinuation of therapy. To better understand the increased risk of metabolic syndrome, diabetes, and heart disease in patients undergoing ADT for prostate cancer, we performed a MEDLINE search (1986-2008) to identify pertinent studies and reports. Additional citations were obtained from the articles retrieved from the literature search. We found that the increased risk for serious cardiovascular disease becomes evident within months of beginning ADT. Pharmacists should provide counseling to these patients on primary disease prevention. Men receiving ADT should be monitored routinely for signs and symptoms of metabolic syndrome, diabetes, and CAD. Healthy lifestyle practices should be encouraged, and physical therapy should be considered for these patients.

    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. PMID:19556587

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

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

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

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

    2014-01-01

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

    The durability of sustained virologic response (SVR) following boceprevir-based therapy in patients with hepatitis C virus (HCV) infection has not been reported. Furthermore, in patients receiving protease inhibitor-based therapies, development of resistance can contribute to treatment failure. The aim of the present study was to follow the clinical progression of patients treated with boceprevir after treatment in phase 2/3 clinical trials. This was a 3-year, long-term follow-up analysis of patients enrolled in boceprevir phase 2/3 studies. No treatment was administered during follow-up. Patients with SVR were assessed for durability of viral eradication. Non-SVR patients with on-treatment resistance-associated variants (RAVs) were assessed for longevity of RAVs. A total of 1148 patients (SVR, n=696; virologic failure, n=452) were enrolled in this follow-up analysis. The median duration of follow-up was approximately 3.4 years (range of 0.0-4.1 years). Overall, 3 of 696 patients with SVR had detectable HCV RNA during the follow-up period (relapse rate of 0.4% or 1.3 relapses/1000 person-years). The majority of patients who developed RAVs during the initial treatment study (228/314, 73%) reverted to wild-type (WT) within 3 years (RAVs persisted in 27% of patients). The median time for all RAVs to become undetectable was 1.11 years (95% confidence interval 1.05-1.20 years). V36M, T54A, A156S, I/V170A and V36M+R155K appeared to have a faster rate of return to WT (median times to return to WT of ⩽0.9 years); whereas, T54S, R155K, V55A and T54S+R155K had a slower rate of return to WT (median times to return to WT of approximately 1.1 years). Return to WT appeared slightly faster in patients with G1b RAVs compared to those with G1a RAVs, and in patients with previous non-response or relapse versus breakthrough or incomplete virologic response. SVR was durable in most patients treated with boceprevir. Furthermore, most RAVs present at the time of virologic failure

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

    To investigate hepatitis B virus (HBV) reactivation and survival in patients with multiple myeloma (MM) receiving bortezomib-containing regimens, we analyzed 139 patients with MM receiving bortezomib-containing regimens in our hospital. Twenty-seven/139 patients were hepatitis B surface antigen positive (HBsAg+) with nine having DNA levels > 500 IU/mL, including four > 1000 IU/mL. All but five HBsAg+ patients were treated with lamivudine or entecavir before chemotherapy until at least 6 months after chemotherapy or autologous stem cell transplant (ASCT). HBV reactivation occurred in six HBsAg+ patients and two HBsAg- patients, including six who received ASCT. Overall survival and progression-free survival of HBsAg- patients were significantly longer than for HBsAg+ patients (both p < 0.01). From these results, we confirmed that the incidence of HBV reactivation was notable in patients with MM receiving bortezomib-containing regimens, especially those who underwent ASCT. HBsAg+ patients with MM had a poorer prognosis than HBsAg- patients. Prophylactic treatment should be prescribed to all patients with HBsAg+ MM for a minimum duration of 12 months.

    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

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

    Severe cases of itraconazole-induced hepatotoxicity have been reported; however, these events are thought to occur very rarely. The available literature is comprised largely of individual case reports and small series that do not report the itraconazole serum concentration at the time of the severe adverse event or apply an objective scale to assess probability of the event being related to drug exposure. We report a case of severe hepatotoxicity after 6 months of itraconazole therapy for histoplasmosis, resulting in acute hepatic failure (aspartate transaminase >20× and alanine transaminase >15× upper limit normal), in the setting of therapeutic serum concentrations (5 mg/mL). Both the Naranjo probability scale and the Roussel Uclaf causality assessment method were used to assess the probability of a causality relationship showing a "probable" and "highly probable" association with itraconazole exposure, respectively. The available literature describing severe hepatotoxicity resulting in hepatic failure associated with itraconazole is also reviewed.

    Impairment of libido and sexual potency are commonly reported by male epileptic patients. This may be partly a consequence of medication. Circulating hormones were measured in 53 postpubertal male epileptic patients less than 45 years of age and in an age-matched control group (n = 40), consisting of 14 untreated epileptic patients and 26 unmedicated healthy subjects. A subgroup also underwent a combined gonadotrophin- and thyrotrophin-releasing hormone (LH-RH/TRH) pituitary stimulation test. Untreated patients did not differ from healthy subjects for any parameter, and their data were combined for comparison with the treated epileptic patients. Total testosterone (T), androstenedione, and basal follicle-stimulating hormone concentrations were similar in all patient groups. Patients receiving more than one drug had higher sex hormone binding globulin (SHBG) (p less than 0.01) and lower free T and dehydroepiandrosterone sulphate (DHAS) levels (both p less than 0.001) than controls. Carbamazepine (CBZ) monotherapy also reduced free T (p less than 0.05) and DHAS (p less than 0.001) and increased basal prolactin (p less than 0.01). In these two groups of patients, basal luteinising hormone (LH) was elevated (p less than 0.01), presumably as a pituitary response to increased T catabolism. There was a negative correlation between free T and circulating CBZ (r = -0.54, p less than 0.05) in the monotherapy patients. Phenytoin (PHT) was associated with a rise in SHBG (p less than 0.01) and a fall in DHAS (p less than 0.001). Basal LH was also elevated, but this just failed to reach statistical significance (p less than 0.1).(ABSTRACT TRUNCATED AT 250 WORDS)

    BACKGROUND In men with metastatic castration-resistant prostate cancer (CRPC), the association of measurable tumor responses with overall survival (OS) is unknown. The authors retrospectively evaluated the TAX327 phase 3 trial to study this relation. METHODS Eligible patients for this analysis included those with World Health Organization (WHO)-defined measurable metastatic disease randomized to receive either docetaxel or mitoxantrone. OS was estimated by using the Kaplan-Meier method, and the prognostic relation of WHO-defined radiologic response with OS was performed by using Cox proportional hazards regression. Landmark analyses evaluated survival from baseline and at 2, 3, 4, and 6 months after baseline. RESULTS Four hundred twelve patients enrolled on the TAX327 trial had measurable tumors. Thirty-seven patients exhibited a complete or partial objective response (CR/PR, 9.0%), 116 had stable disease (SD, 28.2%), 99 had progressive disease (PD, 24%) and 160 (38.8%) did not have a after-baseline objective assessment. Partial responders demonstrated longer median OS (29.0 months) than patients with SD (22.1 months) or those with PD (10.8 months) or those who were not assessed (12.7 months). These results remained after landmark analysis. The authors found a significant association between ≥30% prostate-specific antigen (PSA) declines and radiologic response, with ≥30% PSA declines occurring in all patients with CR/PR, 79.8% of patients with SD, and 34.4% with PD. Radiologic response remained a significant but modest post-treatment prognostic factor for OS after adjusting for treatment, pain response, and ≥30% PSA decline (P = .009). CONCLUSIONS In men with metastatic CRPC and measurable disease receiving chemotherapy, objective tumor response was prognostic for OS and appeared to complement PSA assessment. PMID:21365623

    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

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

    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.

    Objectives The epidemiology of the incidence of sexually-transmitted hepatitis C virus (HCV) infection in HIV-positive men who have sex with men (HIV+MSM) is only partially understood. In the presence of HIV, HCV infection is more likely to become chronic and liver fibrosis progression is accelerated. Design A systematic review and meta-analysis was used to synthesize data characterizing sexually transmitted HCV in HIV+MSM. Methods Electronic and other searches of medical literature (including unpublished reports) were conducted. Eligible studies reported on HCV seroconversion or on reinfection post-successful HCV treatment in HIV+MSM who were not injecting drugs. Pooled incidence rates were calculated using random-effects meta-analysis, and meta-regression was used to assess study-level moderators. Attributable risk measures were calculated from statistically significant associations between exposures and HCV seroconversion. Results More than 13,000 HIV+MSM in 17 studies were followed >91,000 person-years (PY) between 1984–2012; the pooled seroconversion rate was 0.53/100PY. Calendar time was a significant moderator of HCV seroconversion, increasing from an estimated rate of 0.42/100PY in 1991 to 1.09/100PY in 2010, and 1.34/100PY in 2012. Reinfection post-successful HCV treatment (n=2 studies) was 20 times higher than initial seroconversion rates. Among the seroconverters, a large proportion of infections were attributable to high risk behaviors including mucosally-traumatic sex and sex while high on methamphetamine. Conclusions The high reinfection rates and the attributable risk analysis suggest the existence of a subset of HIV+MSM with recurring sexual exposure to HCV. Approaches to HCV control in this population will need to consider the changing epidemiology of HCV infection in MSM. PMID:26258525

    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.

    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 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).

Human genomic and clinical data were collected from 156 consecutive Taiwanese HCV genotype 1 or 2 patients who received pegylated interferon plus ribavirin therapy and 153 non-HCV healthy subjects. Three SNPs(rs10846744, rs5888, and rs3782287) of the SCARB1 gene that have been linked to humans diseases were investigated. rs10846744 rather than rs5888 or rs3782287 was associated with serum HCV RNA level and sustained virologic response(SVR) to pegylated interferon plus ribavirin therapy in CHC patients(GG vs. non-GG genotype, Adjusted Odds Ratio, 95% CI: 0.32, 0.11–0.95, P = 0.039). Among patients with IL28B rs8099917 non-TT genotypes, those with rs10846744 non-GG genotype had a higher SVR rate than those with GG genotypes. In addition, patients with GG genotype had a higher fasting blood glucose level than those with CC genotype. In conclusion, SCARB1 gene polymorphisms may serve as a potential predictor of treatment responses in CHC patients receiving interferon-based therapy. (ClinicalTrials.gov number, NCT02714712).

    Background Men who have sex with men (MSM) are at high risk for hepatitis B virus (HBV) infection. Data on the effect of highly active antiretroviral therapy (HAART) on incident HBV infection in HIV-infected and HIV-uninfected MSM are limited. Objective To determine predictors of incident HBV infection in MSM during pre-HAART and HAART periods. Design Observational cohort study. Setting Cohort of MSM who have, or are at risk for, HIV infection. Patients 2375 HBV-uninfected MSM in the Multicenter AIDS Cohort Study. Measurements Poisson regression was used to compare incidence rates of HBV infection in the pre-HAART and HAART eras and to identify factors associated with incidence of HBV infection. Results In 25 322 person-years of follow-up, 244 incident HBV infections occurred. The unadjusted incidence rate was higher in HIV-infected MSM than in HIV-uninfected MSM (IRR, 1.9 [95% CI, 1.5 to 2.4]) and was significantly lower in the HAART era than in the pre-HAART era among HIV-infected (IRR, 0.2 [CI, 0.1 to 0.4]) and HIV-uninfected (IRR, 0.3 [CI, 0.2 to 0.4]) MSM. Age younger than 40 years (IRR, 2.3 [CI, 1.7 to 3.0]), more than 1 recent sexual partner (IRR, 3.1 [CI, 2.3 to 4.2]), and HIV infection (IRR, 2.4 [CI, 1.8 to 3.1]) were independently associated with higher incidence of HBV infection, whereas HBV vaccination was protective (IRR, 0.3 [CI, 0.2 to 0.4]). Highly active antiretroviral therapy with HIV RNA levels less than 400 copies/mL was associated with protection (IRR, 0.2 [CI, 0.1 to 0.5]), but HAART in those with HIV RNA levels of 400 copies/mL or greater was not. Limitation The observational nature limits inferences about causality. Conclusion Effective HAART is associated with lower incidence of HBV infection; however, even in the HAART era, incidence of HBV infection remains high among MSM.

    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.

    A chronic lymphocytic leukemia patient had achieved complete virological suppression of hepatitis B virus (HBV) by oral antiviral therapy. Unexpectedly, fulminant hepatitis D virus (HDV) reactivation occurred, resulting in mortality. Cloning and sequence analysis identified a novel large fragment HDV deletion mutant containing only 69% of the standard genome. Reverse transcription-PCR assay revealed persistence of this mutant with variations of the wild-type-to-mutant ratios during the clinical course. Serum samples from 405 patients with chronic hepatitis B were then submitted for HDV RNA analysis. Of them, 20 (4.9%) were positive for HDV RNA and 5 HDV RNA large fragment deletions were identified in three patients, all under entecavir treatment. Two of them suffered from acute hepatitis exacerbations leading to liver failure while the third had repeated hepatitis flares. The peak bilirubin levels in these three patients were significantly higher than the others without large fragment deletions (P = 0.003). The deleted regions (527-702 bases) encompassed two ribozyme domains as well as part of the hepatitis D antigen (HDAg) reading frame. In conclusion, exacerbations of hepatitis D could occur, leading to fulminant hepatitis, even after complete virological suppression of HBV. Large fragment HDV RNA deletions were identified in some hepatitis D patients who were treated with entecavir but still experiencing severe hepatitis.

    The present study was undertaken to investigate the possible effects of Fe and trace element exposure on hepatic levels of retinoids in seven fish species. Concentrations of retinoids were measured in fish collected from a coastal lagoon in Brazil that receives effluents from an iron-ore mining and processing plant. Fish from nearby coastal lagoons were also included to assess possible differences related to chemical exposure. Results indicated considerable differences in hepatic retinoid composition among the various species investigated. The most striking differences were in retinol and derivative-specific profiles and in didehydro retinol and derivative-specific profiles. The Perciformes species Geophagus brasiliensis, Tilapia rendalli, Mugil liza, and Cichla ocellaris and the Characiforme Hoplias malabaricus were characterized as retinol and derivative-specific, while the Siluriformes species Hoplosternum littorale and Rhamdia quelen were didehydro retinol and derivative-specific fish species. A negative association was observed between Al, Pb, As, and Cd and hepatic didehydro retinoid levels. Fish with higher levels of hepatic Fe, Cu, and Zn showed unexpectedly significant positive correlations with increased hepatic retinol levels. This finding, associated with the positive relationships between retinol and retinyl palmitate with lipid peroxidation, may suggest that vitamin A is mobilized from other tissues to increase hepatic antioxidant levels for protection against oxidative damage. These data show significant but dissimilar associations between trace element exposure and hepatic retinoid levels in fish species exposed to iron-ore mining and processing effluents, without apparent major impacts on fish health and condition.

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

    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

    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

    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 inpatient treatment program. Forty-eight young adult men received either treatment as usual (TAU) plus three sessions of HRV BFB training over 3 weeks, or TAU only. Participants receiving HRV BFB training were instructed to practice daily using a hand-held 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.

    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.

    Men receiving radiation for prostate cancer frequently want to know what steps they can take to optimize their chance of cure and reduce their risk of side effects. A variety of modifiable behaviors, medications, and complementary alternative medicine interventions have been investigated in this regard. In this review, we summarize data on tobacco use, exercise, statins and aspirin, and vitamins. There is limited randomized data supporting any of the interventions and additional studies are needed before clinicians can confidently inform their patients regarding what steps to take to improve their outcomes.

    Introduction The high prevalence of chronic hepatitis C (CHC) and its consequent cirrhosis has been associated with bone fragility. Whether CHC may cause bone and mineral abnormalities in the absence of hepatocellular dysfunction is still unknown. In this study we aimed to determine the prevalence of osteoporotic vertebral fractures and low BMD measurements in men with non-cirrhotic CHC. Risk factors for low BMD and fractures were also investigated. Methods Morphometric vertebral fractures and BMD measurements were performed in 60 non-cirrhotic untreated men with CHC and 59 healthy controls, matched for age and gender, weight and current smoking. Serum CTx, calcium, phosphate, intact PTH, alkaline phosphatase and vitamin D (25OHD) concentrations were measured in all participants. Clinical risk factors for low BMD and fractures were evaluated by a structured questionnaire as well as details regarding HCV infection. Results Trochanter and total femur BMD were significantly lower in CHC patients as compared to healthy men (p = 0.04). In men 50 years and older, the prevalence of osteoporosis was significantly higher among CHC patients (p = 0.01). Lower levels of physical activities and more often report of prolonged immobilization were observed among CHC patients (p<0.05). Liver inflammation and fibrosis, viral load and genotype did not correlate with BMD measurements. Bone markers and 25OHD concentrations were similar in both groups. Only a few vertebral fractures were observed. Conclusions Our results demonstrate that non-cirrhotic untreated CHC patients have lower BMD at the femur as compared to healthy men in spite of the absence of significant bone and mineral abnormalities.

    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.

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

    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

    The aim of this study was to evaluate the effect of pegylated interferon α-2a plus ribavirin therapy on the quality of life (QOL) of chronic hepatitis C patients when this treatment was paid for by healthcare insurance. The QOL questionnaire (GQOLI-74) was used to assess patient QOL. A total of 42 cases received 1-year pegylated interferon α-2a plus ribavirin treatment paid for by Guangzhou Medical Insurance (group A), and 30 cases received treatment self-subsidized by the patients themselves (group B). Another 30 patients did not receive interferon therapy (group C). All groups completed the evaluation twice; prior to interferon treatment (T0) and at the end of treatment (T1). There was no statistically significant difference among the three groups (P>0.05). At T1, patients in group A had higher scores for each questionnaire dimension and a higher total score than those of group C (P<0.05). Patients in group B also had higher scores than those of group C (P<0.05), except for material well-being (P=0.305). Compared with group B, patients in group A had higher scores for mental function, material well-being and a higher total score (P<0.05). Patients in group A had higher scores for each dimension and a higher total score at T1 than at T0 (P=0.05), while patients in group B had higher scores for physical function, social function and a higher total score at T1 than at T0 (P=0.05). Pegylated interferon α-2a plus ribavirin treatment is able to improve the QOL of chronic hepatitis C patients. Patients whose treatment was financed by medical insurance exhibited increased improvement in QOL compared to those who paid for their own treatment.

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

    Background Serum levels of hepatitis B virus (HBV) DNA are an important predictor of the risk of hepatocellular carcinoma (HCC) in patients with chronic HBV infection. However, little is known about whether high levels of hepatitis B surface antigen (HBsAg) increase the risk for HCC. Methods We investigated 167 patients who were treated with nucleos(t)ide analogues (NA) for at least 2 years (median: 5.8 years, range: 2-13.1 years). Relationships between reduced levels of HBsAg and various factors were evaluated. In addition, we evaluated the usefulness of quantitative serum levels of HBV DNA and HBsAg as predictors of HCC development in patients receiving long-term NA therapy. Results HCC developed in 9 of the 167 NA-treated patients. In the 9 patients with HCC, HBV DNA was undetectable (<2.1 log copies/mL), but HBsAg levels were ≥2000 C.O.I. in 7 patients. No maternal transmission, long NA treatment period, HBV DNA levels <3.0 log copies/mL, and reduced hepatitis B e antigen levels during the first 24 weeks of treatment were a significant factor of HBsAg levels <2000 C.O.I.. Conclusions Hepatocarcinogenesis was observed in patients with high HBsAg levels, despite the negative conversion of HBV DNA as a result of long-term NA therapy. Therefore, to suppress hepatocarcinogenesis, it is important to control not only HBV DNA levels but also HBsAg levels. PMID:24804176

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

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

  15. Hepatic steatosis in HIV-HCV coinfected patients receiving antiretroviral therapy is associated with HCV-related factors but not antiretrovirals

    2012-01-01

    Background In HIV and hepatitis C virus (HCV) coinfected patients, the role of antiretroviral therapy (ART) on hepatic steatosis (HS) remains controversial. Methods HIV/HCV coinfected patients receiving ART and previously untreated for HCV who underwent a liver biopsy were included. Cumulative duration of exposure to each antiretroviral was recorded up to liver biopsy date. Logistic regression analyses evaluated factors associated with steatosis and its severity. Results 184 patients were included: median age 41years, 84% male, 89% Caucasian, 61% with a past history of intravenous drug use. HCV genotypes were 1 (55%), 2 (6%), 3 (26%), and 4 (13%). Median HCV-RNA was 6.18 log10 IU/ml. HIV-RNA was undetectable (<400 copies/ml) in 67% of patients. Median CD4 count was 321/mm3. All patients had been exposed to nucleoside reverse transcriptase inhibitors (median cumulative exposure 56months); 126 received protease inhibitors (23months), and 79 non-nucleoside reverse transcriptase inhibitors (16months). HS was observed in 102 patients (55%): 41% grade 1; 5% grade 2, and 9% grade 3. In multivariate analysis, HCV genotype 3 and HCV viral load were moderately associated with mild steatosis but strongly with grade 2-3 steatosis. After adjustment for the period of biopsy, no association was detected between HS and exposure to any antiretroviral class or drug, or duration of ART globally or comparing genotype 3 to others. Conclusions Among our ART-treated HIV-HCV cohort predominantly infected with genotype 1, 55% of patients had HS which was associated with HCV-related factors, but not ART class or duration of exposure.

    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

    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 > 0.10). 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 or with newer direct acting agents.

    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

    Background/Aims: Nonalchoholic fatty liver disease (NAFLD) has been reported as a hepatic manifestation of metabolic syndrome (MetS); it is common and accounts for 80% of the cases with abnormal liver function tests (LFTs). In addition, several studies have proved that there is a correlation between abnormal LFTs and MetS. Therefore, LFTs may represent the abnormal metabolic status of livers in the patients with MetS. To identify the early state of metabolic dysfunction, we investigate the value of LFTs for the future MetS development in the relatively healthy (non-NAFLD) elderly. Patients and Methods: A total of 16,912 subjects met the criteria for analysis. In the first stage of this study, subjects were enrolled in the cross-sectional study in order to find out the optimal cutoff value in different LFTs with higher chances to have MetS. In the second stage of the present study, subjects with MetS at baseline were excluded from the same study group, and a median 5.6-year longitudinal study was conducted on the rest of the group. Results: Among all LFTs, only aspartate aminotransferase in both genders and the α-fetal protein in women failed to show the significance in distinguishing subjects with MetS by the receiver operating characteristic curve. In the Kaplan–Meier plot, only γ-glutamyl transpeptidase (γ-GT) in men and the alanine aminotransferase (ALT) in women could be used to successfully separate subjects with higher risk of developing the MetS from those with lower risk. Finally, in the multivariant Cox regression model, similar results were identified. Still, the hazard ratio (HR) to have future MetS, γ-GT in men, and ALT in women showed significance (HR = 1.511 in men and 1.504 in women). Conclusion: Among all the different LFTs, γ-GT (>16 U/L) in male and ALT (>21 U/L) in female were the best predictors for the development of MetS in healthy elderly. These two liver markers could be an ancillary test in predicting future MetS development

    Although HCV is more prevalent among people with severe mental illness (SMI; e.g., schizophrenia, bipolar disorder) than in the general population (17% vs 1%), no large previous studies have examined HCV screening in this population. In this cross-sectional study, we examined administrative data for 57 170 California Medicaid enrollees with SMI to identify prevalence and predictors of HCV screening from October 2010 through September 2011. Only 4.7% (2674 of 57 170) received HCV screening, with strongest predictors being nonpsychiatric health care utilization and comorbid substance abuse. PMID:26890183

    Transarterial chemoembolization(TACE) is the palliative treatment of choice for patients with unresectable hepatocellular carcinoma (HCC). The 242 patients prospectively enrolled in this study were diagnosed with HCC and received TACE at Sun Yat-Sen University Cancer Center between October 2014 and March 2015. Patients were divided into study and control groups based on whether parecoxib sodium was administered postoperatively. Postoperative pain, body temperature, vomiting, changes in liver function, physical activity level, length of hospital stay, and tumor control were evaluated. Compared to the control group after propensity score matching, the study group presented less severe postoperative fever. The daily maximum temperatures in the study and control groups were 37.39 vs. 37.82°C on postoperative day 1 (P < 0.001), 37.10 vs. 37.51°C on day 2 (P < 0.001), and 36.90 vs. 37.41°C on day 3 (P < 0.001). The study group also exhibited greater physical activity (P < 0.05) and had shorter hospital stays (7.21 days vs. 7.92 days, P = 0.041). There were no differences in pain scores. Thus administration of parecoxib sodium to HCC patients after TACE effectively relieved fever, promoted postoperative recovery, and shortened the hospital stay. PMID:27056892

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

    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.

    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: 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.

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

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

    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.

    Antecedentes: la hemofilia adquirida es un trastorno infrecuente causado por el desarrollo de inhibidores del factor de coagulación. 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.

    The meningococcal groups C and Y and Haemophilus b (Hib) tetanus toxoid conjugate vaccine (HibMenCY-TT) contains Neisseria meningitidis serogroup C and Y capsular polysaccharide antigens, and Hib capsular polysaccharide [polyribosyl-ribitol-phosphate (PRP)]. The HibMenCY-TT vaccine is available in the USA for use as active immunization to prevent invasive disease caused by N. meningitidis serogroups C (MenC) and Y (MenY), and Hib in children 6 weeks-18 months of age. 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

    Testosterone replacement therapy (TRT) is a widely used treatment for men with symptomatic hypogonadism. The benefits seen with TRT, such as increased libido and energy level, beneficial effects on bone density, strength and muscle as well as cardioprotective effects, have been well-documented. TRT is contraindicated in men with untreated prostate and breast cancer. Men on TRT should be monitored for side-effects such as polycythemia, peripheral edema, cardiac and hepatic dysfunction.

    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.

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

Four men and four women with pre-existing mental health problems who had received hepatitis C virus treatment took part in semi-structured interviews which were analysed using interpretative phenomenological analysis. A central theme of 'Self, stigma and change' was identified which interlinked with three other main themes of 'Coping and responding to treatment', 'Connectedness to others' and 'The impact of information'. These themes and their sub-themes are discussed in relation to existing literature and clinical practice guidelines.

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

    Background. It has been proposed that hepatitis B virus (HBV) sub-genotype A1 infections have mild outcomes and a low risk of drug-resistance among patients infected with human immunodeficiency virus (HIV) receiving lamivudine-containing antiretroviral therapy (ART) without tenofovir in Africa. Methods. The virologic expression of HBV sub-genotype A1 coinfection was studied over 12 months in HIV-positive adults starting stavudine/lamivudine/nevirapine in Malawi, using Sanger, deep, clonal, and single full-genome sequencing for the sensitive characterization of HBV resistance-associated mutations (RAMs). Results. Among 1117 subjects, 133 (12%) tested HBsAg-positive. After starting ART, retention rates were 96/133 (72%) at 6 months and 54/133 (41%) at 12 months. Based upon the last available follow-up, 92/96 (96%) subjects achieved HIV-1 RNA <40 copies/mL, 48/96 (50%) showed HBV DNA <14 IU/mL, and 24/96 (25%) acquired HBV RAMs. At 6 months, M204I was detected in 8/46 (17%) and 16/17 (94%) subjects using Sanger and deep sequencing, respectively. At 12 months, all viremic patients had multiple resistance and compensatory mutations coexisting on the same HBV genomes. Comparing HBeA-positive (67/133, 50%) with HBeAg-negative subjects, 64/67 (96%) vs 35/66 (55%) showed baseline HBV DNA >2000 IU/mL (P = .0006), 39/47 (17%) vs 9/49 (82%) had persistent HBV DNA detection during follow-up (P < .0001), and 23/47 (49%) vs 2/49 (4%) acquired HBV RAMs (P < .0001). Baseline HBV DNA levels were median 8.1 vs 5.3 log10 IU/mL in subjects with vs those without treatment-emergent RAMs (P < .0001). Conclusions. HBV sub-genotype A1 infections showed a severe virologic expression in HIV-positive Malawians. The findings strengthen the urgency of interventions to improve ascertainment and management of chronic hepatitis B in the region. PMID:25100867

    2009-10-01

    Hepatic cystic echinococcosis (HCE) is an emerging disease in central Asia, particularly in Pakistan, due to the migration of infected people. Medical records of patients with HCE admitted between 1995 and 2006 to a tertiary care hospital were reviewed. A total of 106 patients were admitted with a mean age of 34+/-17 years; 60 (56.6%) were men, 72 (67.9%) were residing in rural areas of Pakistan and 21 (19.8%) were Afghan refugees. Twenty-seven (25.4%) had extra hepatic cysts and liver cysts. All patients received albendazole. Percutaneous aspiration, instillation and reaspirarion was done in 14 (13.2%) patients and 71 (66.9%) underwent surgery. Three (2.8%) died and 14 (13.2%) had morbidity. This is one of the largest series of HCE reported from Pakistan. HCE is mostly prevalent in rural areas and among Afghan refugees with low mortality and recurrence, but with significant morbidity.

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

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

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

    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.

    Autoimmune hepatitis is an unresolving, hepatocellular inflammation of unknown cause that is characterized by the presence of periportal hepatitis on histologic examination, tissue autoantibodies in serum, and hypergammaglobulinemia. By international consensus, the designation autoimmune hepatitis has replaced alternative terms for the condition. Three types of autoimmune hepatitis have been proposed based on immunoserologic findings. Type 1 autoimmune hepatitis is characterized by the presence of antinuclear antibodies (ANA) or smooth muscle antibodies (SMA) (or both) in serum. Seventy percent of patients with type 1 of autoimmune hepatitis are women. This type is the most common form and accounts for at least 80% of cases. Type 2 is characterized by the presence of antibodies to liver-kidney microsome type 1 (anti-LKM1) in serum. Patients with this type of autoimmune hepatitis are predominantly children. Type 3 autoimmune hepatitis is characterized by the presence of antibodies to soluble liver antigen (anti-SLA) in serum. There are no individual features that are pathognomonic of autoimmune hepatitis, and its diagnosis requires the confident exclusion of other conditions. The large majority of patients show satisfactory response to corticosteroid (usually prednisone or prednisolone) therapy. For the past 30 years it has been customary to add azathioprine as a "steroid sparing" agent to allow lower doses of steroids to be used and remission, once achieved, can be sustained in many patients with azathioprine alone after steroid withdrawal. Patients with autoimmune hepatitis who have decompensated during or after corticosteroid therapy are candidates for liver transplantation.

    Three forms of viral hepatitis can be recognized: hepatitis A, hepatitis B, and hepatitis non-A, non-B. Hepatitis A is caused by a picornavirus, is transmitted by the faceal—oral route, does not become chronic, and no chronic virus carriers exist. The virus can be grown in cell cultures, and killed as well as live attenuated virus vaccines are under development. Hepatitis B is caused by an enveloped virus containing a circular, double-stranded form of DNA. The disease is transmitted parenterally through inoculation of blood or blood products containing virus or through close personal contact with a virus-positive person. Hepatitis B becomes chronic in a certain number of cases and can lead to cirrhosis and primary liver cell carcinoma. The blood and certain body secretions of individuals with a persistent or chronic infection may remain infectious for many years. The hepatitis B virus cannot be grown in cell cultures but the entire genome has been sequenced and cloned in bacterial and eukaryotic cells. An inactivated virus vaccine has been prepared from hepatitis B surface antigen present in the plasma of hepatitis B virus carriers and further vaccines are under development. The agents of hepatitis non-A, non-B have not been identified. It is possible to distinguish between a predominantly parenterally transmitted and an orally transmitted form of hepatitis non-A, non-B. The latter is reported to be caused by a picornavirus that does not, however, have any antigenic relationship with hepatitis A virus. PMID:6817933

    Autoimmune hepatitis can present as either acute or chronic disease in children. Clinical and laboratory features, including association with extrahepatic autoimmune syndromes and prompt response to immunosuppressive treatment, circulating autoantibodies and hypergammaglobulinemia, suggest an immune etiology. However, the disease mechanism remains uncertain. Different types of autoimmune hepatitis are defined on the basis of which autoantibodies are present: anti-smooth muscle (type 1), anti-liver/kidney microsomal (type 2), or anti-soluble liver antigen (type 3). Diseases which may be clinically similar to autoimmune hepatitis must be excluded before the diagnosis of autoimmune hepatitis is established: Wilson's disease, primary sclerosing cholangitis, chronic hepatitis B or C, and drug-induced liver disease are among the most important entities. Corticosteroids alone or with azathioprine constitute the usual treatment for autoimmune hepatitis. Although some children achieve a complete remission, or even recovery, and can stop immunosuppressive treatment, others required low-dose prednisone treatment indefinitely.

    Acute and chronic autoimmune hepatitis are uncommon inflammatory liver diseases, mainly occurring in young women, in association with hypergammaglobulinemia and serum autoantibodies. Different types have been described: type 1 characterized by anti-smooth muscle and anti-nuclear antibodies; type 2 characterized by anti-LKM1 antibodies; type 3 characterized by anti-SLA antibodies. Other types, still not clearly defined, may exist. Autoimmune hepatitis are associated with HLA A1 B8 DR3 and HLA DR4. Without any treatment, the disease leads to cirrhosis and, uncommonly, to fulminant hepatitis. Large doses of corticosteroids usually allow to control the disease. Relapse of hepatitis is frequent after corticosteroid withdrawal. Concomitant administration of immunosuppressive agents such as azathioprine allows to reduce corticosteroid dosage and contributes to maintain the remission of the disease. Liver transplantation may be indicated in cases of severe cirrhosis or fulminant hepatitis.

    Sarcoidosis is a multisystem disease characterized by the presence of non-caseating granulomas in affected organs. Pulmonary involvement is the most common site of disease activity. However, hepatic involvement is also common in sarcoidosis, occurring in up to 70% of patients. Most patients with liver involvement are asymptomatic. Therefore, the majority of cases are discovered incidentally, frequently by the finding of elevated liver enzymes. Pain in the right upper quadrant of the abdomen, fatigue, pruritus, and jaundice may be associated with liver involvement. Portal hypertension and cirrhosis are complications linked to long-standing hepatic sarcoidosis. Liver biopsy is usually required to confirm the diagnosis. It is important to differentiate hepatic sarcoidosis from other autoimmune and granulomatous liver diseases. Not all cases of hepatic sarcoidosis require treatment. For symptomatic patients, the first line treatment includes corticosteroids or ursodeoxycholic acid. Various immunosuppressant agents can be used as second line agents. Rarely, severe cases require liver transplantation.

    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.

    Background: Many Japanese patients with hepatic disorders confirmed on diagnostic imaging and coexisting upper gastrointestinal (GI) peptic lesions receive treatment with proton pump inhibitors. Some pharmacotherapies used to treat peptic ulcers have been associated with adverse drug reactions (ADRs), including elevated liver enzyme levels. Objective: The aim of this study was to determine the tolerability and effectiveness of rabeprazole sodium in treating peptic lesions in patients with coexisting hepatic disorders. Methods: This open-label, practice-based, postmarketing surveillance investigation was conducted at 15 centers across Japan. Male and female patients aged ≥18 years with peptic lesions confirmed on upper GI endoscopy and with underlying hepatic disease were enrolled. Patients were randomly assigned to receive rabeprazole 10 or 20 mg PO (tablet) QD after a meal for up to 8 weeks. Tolerability was assessed using monitoring of the incidence of ADRs determined by direct patient questioning, spontaneous reporting, and laboratory assessment. All patients who received at least 1 dose of study drug were included in the tolerability assessment. Effectiveness was assessed at baseline and study end using the rates of achievement of improvement on endoscopy, relief of subjective/objective symptoms (rates of improvement in epigastric pain and heartburn), and global improvement. The effectiveness analysis included all patients with complete data before and after treatment. Subanalyses were conducted to determine the effectiveness of drug by identification of the proportion of patients with coexisting hepatic disorders (cirrhosis, chronic hepatitis, and other hepatic diseases [eg, alcoholic hepatitis, fatty liver]) and by peptic lesion (gastric ulcer, duodenal ulcer, stomal ulcer, and reflux esophagitis) who achieved improvement. Results: A total of 114 patients were enrolled; 108 patients were included in the tolerability analysis (81 men, 27 women; mean age, 59

    2016-02-01

    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.

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

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

    Sarcoidosis is a multisystem disease of unknown aetiology. Histological evidence of non-caseating granulomas represents the main finding. It affects mostly young people, targeting primary the lung and hilar lymph nodes although liver involvement is often encountered. Hepatic sarcoidosis covers a broad spectrum from asymptomatic hepatic granulomas formation and slightly deranged liver function tests to clinically evident disease with cholestasis or, in advanced cases, cirrhosis and portal hypertension. Other granulomatous diseases (mainly systemic infections like tuberculosis) should be excluded prior to treatment, as longstanding corticosteroid administration is the main stem of therapy. In advanced cases, liver transplantation represents the ultimate therapeutic option.

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

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

    The hepatitis C virus (HCV) genome was isolated during the late 1980s using molecular cloning techniques. It is recognized as the cause of most cases of percutaneously transmitted non-A, non-B hepatitis. Prevalence of antibodies to HCV(anti-HCV) in the general Australian population is 0.3%. However, among regular intravenous drug users the prevalence exceeds 90%. The predominant risk factors for HCV are intravenous drug use, tattoos, exposure to blood products, occupational risk and ethnicity. In contrast to hepatitis B, sexual spread and vertical transmission of HCV from mother to neonate are relatively uncommon. The risk of acquiring HCV from a single HCV-contaminated needlestick accident is about 5%. Most cases of acute HCV infection are asymptomatic, but 50 to 80% progress to chronic disease. The percentage of those with chronic HCV progressing to cirrhosis is not accurately known, but is probably 20%. Treatment strategies for HCV, utilizing recombinant interferons, are proving useful in patients with mild to moderate liver disease, but fare less well in patients with cirrhosis. Currently, there is no vaccine for hepatitis C, so pre-exposure prophylaxis is not possible. Equally, no post-exposure intervention, for example with gamma globulin, has been shown to be beneficial, though there may be a role for early interferon therapy.

  6. Antidepressant prophylaxis reduces depression risk but does not improve sustained virological response in hepatitis C patients receiving interferon without depression at baseline: A systematic review and meta-analysis

    2013-01-01

    BACKGROUND: Depression complicates interferon-based hepatitis C virus (HCV) antiviral therapy in 10% to 40% of cases, and diminishes patient well-being and ability to complete a full course of therapy. As a consequence, the likelihood of achieving a sustained virological response (SVR [ie, permanent viral eradication]) is reduced. OBJECTIVE: To systematically review the evidence of whether preemptive antidepressant prophylaxis started before HCV antiviral initiation is beneficial. METHODS: Inclusion was restricted to randomized controlled trials in which prophylactic antidepressant therapy was started at least two weeks before the initiation of HCV antiviral treatment. Studies pertaining to patients with active or recent depressive symptoms before commencing HCV antiviral therapy were excluded. English language articles from 1946 to July 2012 were included. The MEDLINE, Embase and Cochrane Central databases were searched. Where possible, meta-analyses were conducted evaluating the effect of antidepressant prophylaxis on SVR and major depression as well as on Montgomery-Asberg Depression Rating Scale and Beck Depression Index scores at four, 12 and 24 weeks. The Cochrane Collaboration tool was used to assess bias risk. RESULTS: Six randomized clinical trials involving 522 patients met the inclusion criteria. Although the frequency of on-treatment clinical depression was decreased with antidepressant prophylaxis (risk ratio 0.60 [95% CI 0.38 to 0.93]; P=0.02; I2=24%), no benefit to SVR was identified (risk ratio 1.08 [95% CI 0.74 to 1.57]; P=0.69; I2=58%). CONCLUSION: This practice is not justified to improve SVR in populations free of active depressive symptoms leading up to HCV antiviral therapy. PMID:24106729

Syphilis can affect the liver during the secondary stage as syphilitic hepatitis and during the tertiary stage as gummas. We describe 3 cases of syphilis in human immunodeficiency virus-positive homosexual men that presented as hepatic mass lesions clinically suspected of being malignant tumors. Histologically, 2 of the 3 cases showed a plump spindle cell proliferation, mixed inflammatory infiltrate with numerous neutrophils, and abscesses, whereas the third case showed granulomas and pericholangitis/cholangitis. Immunohistochemical staining for T. pallidum showed innumerable organisms in 2 of the cases. Pathologists must be aware of the possibility of syphilis causing hepatic inflammatory masses in human immunodeficiency virus-positive men who have sex with men in order to avoid misdiagnosis or delayed treatment.

    We have analyzed 8 patients (6 men and 2 women, aged 52 to 70 years) with psoriasis associated with hepatitis C virus (HCV) infection among 79 psoriatic patients. Psoriasis preceded in 6 cases. One patient had generalized pustular psoriasis (GPP), and the others had psoriasis vulgaris (PV). The psoriasis area and severity index (PASI) score ranged from 2.7 to 32.4. Two of the patients were treated with interferon-gamma. Anti-HCV antibodies were detected in all cases by second generation enzyme-linked immunosorbent and recombinant immunoblot assay. HCV messenger RNA was demonstrated by reverse transcriptase polymerase chain reaction in the tissue sections of the lesions of 1 of the patients with PV and the patient with GPP, providing evidence for active viral replication in the skin lesion. HCV-related chronic active hepatitis might cause several immunological abnormalities. It is suggested that this infection might be one of the triggering factors of psoriasis.

    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

    2008-01-01

    Chronic heart failure (HF) is a major cause of morbidity and mortality, and is the reason for more than one in five of all hospital admissions in patients aged >65 years. Major advances in the diagnosis and treatment of HF over the last two decades have proven effective in reducing morbidity and mortality among both men and women, but with less improvement for women and elderly patients. Women and men with HF differ in several respects. Women tend to be older and more often hypertensive, but are less likely to demonstrate any clinical evidence of coronary heart disease (CHD) and more often have preserved ventricular function. Conversely, hypertension plays a greater role in the development of HF in women than in men. Sex differences in systolic and diastolic function in patients with hypertension have been demonstrated. Although men have higher incidence of HF at all ages, lifetime risk is similar in men and women because women live longer. Intervention studies have included far more men than women but in patients with reduced ventricular function there is no evidence to suggest that women benefit less than men from evidence-based treatments, and current guidelines do not differentiate between men and women. There is no consistent recent evidence that women receive poorer quality of care than men. Women with HF have better survival rates than men, which may be due to better systolic function or less CHD among women; however, mortality rates for HF are still very high regardless of sex. As most trials have been targeted towards patients with left ventricular systolic dysfunction, which is less typical for women than for men with HF, more research is needed to help define treatment aimed at improving prognosis for patients with HF and preserved systolic function. In light of these differences and ongoing uncertainties, future European guidelines should incorporate gender issues. Heart Fail Monit 2008;6(1):34-40. PMID:18607520

    2013-01-01

    Objectives 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. Methods Nationally representative data from 2006-2010 National Survey of Family Growth was used to examine pregnancy intentions and happiness for all births reported by men in the five 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. Results 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. Conclusions 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. PMID:23793481

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

    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.

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

    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.

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

    Reactivation of hepatitis B virus (HBV) in HBV surface antigen (HBsAg)-positive patients treated with cytotoxic chemotherapy is well known. HBV reactivation in patients with HBV and hepatitis C virus (HCV) coinfection caused by direct-acting antiviral (DAA) therapy has also recently been reported. We report a case of acute hepatitis B in a patient with HCV infection after DAA therapy. An 83-year-old woman was referred for chronic hepatitis C. She was infected with HCV genotype 1b and negative for HBsAg at baseline. She received daclatasvir and asunaprevir therapy, and HCV became negative at 4 weeks and remained negative until 6 months after the end of DAA therapy. Acute hepatitis B developed 5 months after ending DAA therapy. Genome sequencing revealed the subgenotype as B1, and the serological subtype as adr. T118 K mutation at the S region as an immune escape mutant was identified. These virologic features led to HBV reactivation. The presence of hepatitis B core antibody or HBs antibody was not determined before DAA therapy, so prior HBV infection status was unclear. This case is speculated to represent HBV reactivation in a patient with previously resolved HBV induced by DAA therapy, based on virologic analysis and clinical status. The risk might be very low, but DAA therapy can cause HBV reactivation in chronic hepatitis C patients with prior HBV infection. When acute hepatitis emerges in patients who have received DAA therapy for HCV, HBV reactivation should be considered to allow early initiation of anti-HBV therapy. PMID:27329484

    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.

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

    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

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

    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).

  12. Hepatitis B flares in chronic hepatitis B: pathogenesis, natural course, and management.

    PubMed

    Chang, Ming-Ling; Liaw, Yun-Fan

    2014-12-01

    Hepatitis B flare, defined as an event with abrupt rise of alanine aminotransferase (ALT) levels to >5 times the upper limit of normal during chronic hepatitis B virus (HBV) infection, is considered to be the result of a human leukocyte antigen-I restricted, cytotoxic T lymphocyte mediated immune response against HBV and its downstream mechanisms. It may occur spontaneously, during or after antiviral therapy and in the setting of immunosuppression and/or chemotherapy. The clinical spectrum of hepatitis B flares varies from asymptomatic to symptomatic and typical overt acute hepatitis, even with hepatic decompensation or failure. Flares may also occur in viraemic patients with cirrhosis with higher incidence of decompensation/mortality, hence requiring immediate antiviral therapy. An upsurge of serum HBV DNA and hepatitis B surface antigen levels usually precedes the abrupt rise of ALT levels. Rising or stable and high HBV DNA during flares represent ineffective immune clearance and further hepatocytolysis, even hepatic decompensation, may occur. Such patients require immediate antiviral therapy. In contrast, bridging hepatic necrosis and/or alpha-fetoprotein levels >100 ng/ml or decreasing HBV DNA during flares represent a more effective immune clearance and frequently leads to seroclearance of HBV DNA and/or hepatitis B e antigen with remission. If patients are non-cirrhotic and there is no concern of developing decompensation, patients may be observed for 3-6 months before deciding on the need of antiviral therapy. Severe and repeated flares are prone to develop into decompensation or lead to the development of cirrhosis, thus a timely treatment to prevent the hepatitis B flare is better than to cope with the flare. Screening, monitoring and prophylactic or pre-emptive antiviral therapy is mandatory for patients who are going to receive immunosuppressants or chemotherapy.

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

    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.

    Family planning programs since their beginnings have focused exclusively on women. The importance of male participation in family planning has not been recognized. Today's society demands greater understanding and empathy between spouses, if they are to meet the new and difficult challenges of modern life. Incorporation of men into family planning programs is needed because of the deteriorating live conditions of a large segment of the population and the accelerating decomposition of social structures. Persuading men to participate in family planning should strengthen the couple and increase the probability that decisions about family size will be responsible. Strategies should be designed to interest men in family planning and increase their awareness of their role in fathering happy children who enter the world in more just and humane conditions. Such strategies must combat sex role socialization that begins in infancy. The assignment of responsibility for family planning to the woman excludes men from what should be a fundamental role.

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

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

    Asian Americans are one of the more under-researched groups in the United States. This holds true with regard to research on risk assessment, screening, and testing for human immunodeficiency virus (HIV) and hepatitis C (HCV). Here, we address that lack by exploring correlates of risk and testing for the two diseases among Chinese, Filipino, and Vietnamese men who have sex with men (MSM) and other at-risk men in the San Francisco Bay Area. We do so by analyzing findings from the study of a community-based prevention program, Project 3-3-3 (P333), designed to address the often comorbid conditions of substance abuse, HIV infection, and HCV infection among underserved and high-risk Chinese, Filipino, and Vietnamese adults, most of whom are MSM. A risk-behavior survey completed at preintervention identified risk factors related to HIV, HCV, and substance use among this population (n = 273). The study of survey data identifies and distinguishes between correlates of HIV and HCV testing. Among our findings, significant differences were found between Asian ethnic subpopulation groups with respect to number of sexual partners (p = .007), and HIV testing rates comparing MSM and heterosexual men differed significantly (p < .002). Those who spoke English at home were more likely to be tested for HIV (p < .008). With HCV testing, the number of partners was positively correlated to getting tested (p < .047), and Filipino men were significantly more likely to get tested for HCV than Chinese men (p < .022).

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

    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".

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

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

    Sex education should be oriented toward men and their role in healthy sex practices. By promoting condom usage as a contraceptive method and a preventive method against sexually transmitted diseases, family planning programs could effectively involve men in practicing safe sex. Some misconceptions among men about this contraceptive barrier include decreased sexual sensations during intercourse, partners being offended, and disruption of sexual intercourse. To increase their usage, programs must focus on creating a positive image of the condom. Advantages include no side-effects, easy use, and protection against unwanted pregnancies and sexually transmitted diseases. Proper condom use should be emphasized to increase its usage among men. Condoms could be made more accessible through vending machines or community-based distribution centers. Male sex and contraceptive knowledge may be further enhanced by employing males counselors to train man in contraceptive and preventive measures. 2 organizations which have effectively involved men in promoting safe sex are The Planned Parenthood Association of Ghana (PPAG) and The Family Planning Association of Nepal (FPAN). PPAG integrates sex and health education with recreation. FPAN promotes condom usage through health and social services, media, and condom dispensers. Through condom usage, men become more responsible sexual partners.

    Suicide is second to only accidental death as the leading cause of mortality in young men across the world. Although suicide rates for young men have fallen in some high-income and middle-income countries since the 1990s, wider mortality measures indicate that rates remain high in specific regions, ethnic groups, and socioeconomic groups within those nations where rates have fallen, and that young men account for a substantial proportion of the economic cost of suicide. High-lethality methods of suicide are preferred by young men: hanging and firearms in high-income countries, pesticide poisoning in the Indian subcontinent, and charcoal-burning in east Asia. Risk factors for young men include psychiatric illness, substance misuse, lower socioeconomic status, rural residence, and single marital status. Population-level factors include unemployment, social deprivation, and media reporting of suicide. Few interventions to reduce suicides in young men have been assessed. Efforts to change help-seeking behaviour and to restrict access to frequently used methods hold the most promise.

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

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

    INTRODUCTION: Hepatic epithelioid hemangioendothelioma (HEHE) is a rare entity. At the present time, there is no standardized effective therapy. Liver transplantation (LT) has emerged as a treatment for this rare tumour. OBJECTIVE: To evaluate the outcome of liver transplantation for HEHE at eight centres across Canada. METHODS: The charts of patients who were transplanted for HEHE at eight centres across Canada were reviewed. RESULTS: A total of 11 individuals (eight women and three men) received a LT for HEHE. All LTs were performed between 1991 and 2005. The mean (± SD) age at LT was 38.7±13 years. One patient had one large liver lesion (17 cm × 14 cm × 13 cm), one had three lesions, one had four lesions and eight had extensive (five or more) liver lesions. One patient had spleen involvement and two had involved lymph nodes at the time of transplantation. The mean duration of follow-up was 78±63 months (median 81 months). Four patients (36.4%) developed recurrence of HEHE with a mean time to recurrence of 25±25 months (median 15.6 months) following LT. The calculated survival rate following LT for HEHE was 82% at five years. CONCLUSIONS: The results of LT for HEHE are encouraging, with a recurrence rate of 36.4% and a five-year survival rate of 82%. Further studies are needed to help identify patients who would benefit most from LT for this rare tumour. PMID:18925305

    1982-11-01

    Personal and professional characteristics of men and women hospital pharmacy residents were studied to identify differences that could affect future hospital pharmacy practice. Residents in 111 ASHP-accredited pharmacy residency programs received a survey containing questions on demographic information, reasons for selecting a residency, areas of professional interest, postresidency career goals, responsibilities to home and family, and advantages and disadvantages associated with gender. Of 286 residents receiving questionnaires, 226 responded; the percentages of men and women responding corresponded to the ratio of men and women in hospital pharmacy residencies. While men and women expressed educational goals that were not significantly different, more men than women had earned or were in the process of earning advanced degrees. No significant differences were evident between men's and women's plans for marriage and children, but 73% of the women indicated that they would take time out from their practice to raise children, compared with only 9% of the men. The majority of residents did not think their gender affected them in their residency programs, but in professional interactions more men saw gender as an advantage and more women as a disadvantage. Significantly more than women aspired to be hospital pharmacy directors. The results suggest that men are obtaining advanced training closer to the time they graduate from pharmacy school and that in the future women competing for promotions may be older than men competing for comparable positions. Those planning pharmacy staffing should consider the needs of women, and men, who expect to take time out from their careers for family responsibilities and possibly seek part-time positions when they return to the work force.

    2003-01-01

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

    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

    The paper discusses the articulation among epidemiological information systems, scientific production and men's health policies. Three secondary sources were used: data from the Ministry of Health (Mortality and Hospital Information Systems, Surveillance of Protection and Risk Factors for Chronic Diseases through Telephone Survey), papers published in SciELO, and documents of the Ministry of Health regarding men's health. The results indicate that, in terms of morbidity and mortality, men are more exposed to risks than women. In the scientific production, studies focus predominantly on injuries and diseases that affect exclusively the male population, to the detriment of other health-related aspects. Legal documents highlight the epidemiological panorama of male morbidity and mortality and the policy-making methodology. Researchers need to expand the use of data from the epidemiological information systems of the Ministry of Health and to incorporate the gender relational perspective critically.

    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.

    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.

    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.

  12. Receiver Gain Modulation Circuit

    2011-01-01

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

    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.

    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.

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

    The adult formulation of this combination hepatitis A-hepatitis B vaccine contains 720 enzyme-linked immunosorbent assay units (EU) of formalin-inactivated hepatitis A virus strain HM175 and 20mug of recombinant DNA yeast-derived hepatitis B surface antigen adsorbed onto aluminium salts in 1ml for injection. The paediatric formulation contains half this dosage in 0.5ml for injection. The combination vaccine has been shown to be highly immunogenic in healthy young adults after the full dosage schedule of 3 doses at 0, 1 and 6 months. Trials in older adults and children indicate that immunogenicity is adequate in these groups also. The immunogenicity of the combination vaccine appears to be similar to that of hepatitis A vaccine and hepatitis B vaccine administered separately. Possible advantages for the combination vaccine recipient include fewer injections and lower costs. Local adverse reactions such as soreness at the injection site, redness and swelling occur often with the first dose of the series, but the incidence falls with subsequent doses. Local reactions are usually mild and transient, and reported systemic reactions (fatigue, headache) are thought not to have a causal link with the vaccine. PMID:18020513

    A total of 379 men from the greater Copenhagen area were invited to fill out a questionnaire about sexual habits and use of contraception in connection with conscription for military duty. A total of 334 (88%) answered the questionnaire. In the autumn of 1988, a total of 27 men answered the test questionnaire, while in the spring of 1989, when the real study was conducted, 307 men answered it. The median age of 334 participants was 18 years (range of 17-29 years). 33% of the group stated that they had used condoms during first intercourse, while 47% had not. 1 person reported to be exclusively attracted sexually to men, 5 persons were attracted both to men and women, but 97% were exclusively attracted to women. 82% had had intercourse or other sexual experience with women. 1.8% had had intercourse or other sexual experience with men. 8% had no sexual experience, and 8% did not answer the question. Oral contraceptives were used by 60% and the condom by 56%. 10% had used coitus interruptus at one time or another; 15% had used no contraception; 5% used the IUD; and 5% used the diaphragm. Some gave several answers. 1% used spermicidal lotion. 60% thought that it was the responsibility of both men and women to be concerned about contraception, 12% opined that it was exclusively men's duty, and 2% that it was exclusively women's, while 26% did not answer. 68% wanted to use the condom in the future for protection, 24% did not know, but 8% did not want to use it more extensively. 64% did not think that the fear of AIDS would affect their sexual life, but 36% thought it would. Several of the subjects indicated that they would be more careful about choosing a partner, and every 10th suggested that they would use the condom with a new partner. One person (0.3%) was a drug addict, 89% had never injected drugs, but about 11% did not answer about drugs. 97% and 95%, respectively, indicated that the condom provided good protection against pregnancy and venereal diseases.

    Osteoporosis in men, despite being a less important public health problem than osteoporosis in women, should not be neglected as it has many deleterious effects as well as social and economic costs. Finding the cause of osteoporosis is more complex in men than in women, and prevention should be based on an early evaluation of the various possible risk factors and on taking up measures that tend to maximise the peak bone mass. Further studies need to be carried out in order to establish the differences and similarities that characterise this phenomenon when considering different sexes.

    The infectivity of hepatitis D virus (HDV) was evaluated by intravenous inoculation of chimpanzees. HDV was present in the inoculum at a titer of 10(11) chimpanzee infectious doses (CID). In contrast, the titer of hepatitis B virus (HBV) in the same inoculum was 10(6) CID. All HBV-infected chimpanzees inoculated with less than or equal to 10(-11) dilutions of the HDV-positive plasma were superinfected; an animal receiving a 10(-12) dilution did not develop markers of HDV replication in serum or liver. All HDV-infected chimpanzees had marked elevations of serum alanine aminotransferase activities. The incubation period from exposure to development of hepatitis was inversely related to the dose of HDV inoculum, although the severity and duration of hepatitis were independent of it. All animals recovered and rapidly developed antibody to hepatitis D antigen.

    The burden of chronic hepatitis B is substantial in China. An estimated 90 million people are living with chronic hepatitis B. About 7.4 million people are at high risk of advance stage liver disease and cancer due to chronic hepatitis B and who urgently require treatment. However, only 12.5% of chronic hepatitis B patients are receiving antiviral treatment at present. In order to improve the accessibility of antiviral treatment for chronic hepatitis B we should decrease the price of antiviral drugs; to bring antiviral drugs into the national essential drugs list; to include antiviral drugs in both inpatient and outpatient reimbursement category; to apply the mechanisms for drug price reduction such as rejecting the patent registration for drugs with public health risk and harm to welfare policy; initiating government unified price negotiations with drug companies.

    Today's college students occupy a "window" between older adults, whose need for hepatitis B vaccination is minimal, and younger people who receive the vaccine as part of their childhood immunization series. However, because of the high-risk activities that are often part of student behavior, college students are among the individuals who are at the highest risk for this disease; 75% of all reported hepatitis B cases occur in persons between the ages of 15 and 39 years. It is therefore imperative that college health professionals take seriously their responsibility to educate students about issues related to hepatitis B and make available programs that enable the students to receive immunizations. This article briefly describes a successful hepatitis B education and immunization program at an institution that has no mandatory prematriculation immunization requirements.

    Although healthy eating might enhance long-term survival, few men with prostate cancer make diet changes to advance their well-being. Men's typically poor diets and uninterest in self-health may impede nutrition interventions and diet change. Food choice behavior is complex involving many determinants, including gender, which can shape men's health practices, diets, and prostate cancer experiences. Developing men-centered prostate cancer nutrition interventions to engage men (and where appropriate their partners) in promoting healthy diets can afford health benefits. This article presents an overview and synthesis of current knowledge about men's food practices and provides an analysis of diet and diet change behaviors for men with prostate cancer. Masculinity and gender relations theory are discussed in the context of men's food practices, and suggestions for future applications to nutrition and prostate cancer research and diet interventions are made.

    To assess the potential for HIV acquisition among men who have sex with men (MSM) in Guangzhou, China, we conducted a cross-sectional, anonymous, face-to-face survey of MSM in the metropolitan area of Guangzhou, China. As a pilot recruitment for a cohort study, participants were recruited by convenience sampling through newspaper and television advertising, website information, and respondent referral. Blood samples were tested for HIV, hepatitis B (HBV), hepatitis C (HCV), and syphilis. Client-centered HIV and STD counseling was provided.A total of 201 MSM were interviewed and 200 blood samples were tested. The prevalence of HIV antibody was 0% (97.5% CI 0-1.8%); 17.5% of MSM were HBV surface antigen positive; 1.0% had HCV antibodies; 10.5% had antibodies to syphilis. Syphilis seropositivity was associated with sex with a foreign MSM in the last six months and 10.4% reported sex with a foreign MSM overall. The majority (54.7%) reported unprotected anal sex with other men. Nearly one-third (31.8%) had regular female partners; 25.9% were currently married to a woman; 6% had casual female partners; 4.5% had sex with a female sex worker; 4.5% had sex with a male sex worker; and 12.9% had unprotected vaginal sex and unprotected anal sex with a man in the past six months. Only one MSM reported injection drug use (0.5%). The currently low prevalence of HIV but high level of unprotected anal sex, high prevalence of syphilis infection, and sexual networks that include foreign MSM point to a transient window for HIV prevention among MSM in Guangzhou. We recognize challenges to recruiting a representative sample of MSM and retaining them in longitudinal cohort studies. PMID:16802197

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.

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.

    Objectives This study aimed to evaluate the level of hepatitis B immunity among undergraduate students 23 years after commencement of the nationwide hepatitis B childhood immunization program in Malaysia. Methods A total of 402 serum samples obtained from volunteer undergraduate students were screened for the presence of hepatitis B surface antibodies using qualitative ELISA. Results Results showed that 62.7% of volunteers had protective anti-hepatitis B surface antigens (≥10 IU/L), of whom 67.9% received three doses of the vaccine. The estimated post-vaccination immunity was found to be at least 20 years, indicating persistent immunity against hepatitis B and a significant association (P < 0.05) with duration of vaccination. Anamnestic response 1 month post-hepatitis B booster was 94.0% and highly significant (P < 0.01). Isolated antihepatitis B core antigen (anti-HBc) prevalence was found to be 5.0%, all having had a positive anamnestic response. Conclusion Immunity after primary vaccination with hepatitis B recombinant vaccine persists for at least 20 years post-vaccination, with significant association with the number of vaccinations. Furthermore, the presence of anamnestic response to booster vaccine indicates long-lasting immunity despite decreasing antibody levels; therefore, the need for hepatitis B vaccine boosters may not be of significant benefit after complete infant vaccination.

    While substantial attention has been paid to the issue of sexual dysfunction in men on chronic dialysis, less is known about this problem in women with end-stage renal disease. We sought to assess sexual dysfunction in women on chronic dialysis and determine whether patients discuss this problem with their providers and receive treatment. We prospectively enrolled women receiving chronic hemodialysis or peritoneal dialysis in Pittsburgh, PA. We asked patients to complete the 19-item Female Sexual Function Index (FSFI) to assess sexual function and a 5-item survey that assessed whether patients had discussed sexual dysfunction with their providers and/or received treatment for this problem in the past. We enrolled 66 patients; 59 (89%) on hemodialysis and 7 (11%) on peritoneal dialysis. All patients completed the FSFI, of whom 53 (80%) had FSFI scores <26.55, consistent with the presence of sexual dysfunction. Of 37 patients who were married or residing with a significant other, 27 (73%) had sexual dysfunction. Among 24 participants who reported having been sexually active over the previous 4 weeks, 11 (46%) had sexual dysfunction. Only 21% of patients with sexual dysfunction had discussed this problem with their gynecologist, renal or primary provider, and 3 (6%) reported having received treatment. Sexual dysfunction is common in women on dialysis, even among patients who are married or residing with a significant other and those who are sexually active. However, few women discuss this issue with their providers or receive treatment.

This 1998 reanalysis by Blanchard, Zucker, Siegelman, Dickey, and Klassen also confirmed the later birth order of homosexual men.

    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.

    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.

    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

    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

  10. A digital beacon receiver

    Ransome, Peter D.

    1988-01-01

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

    The aim of this study was to compare the effect of different long-term chelation regimens on heart and liver iron stores with the use of T2* magnetic resonance imaging (MRI) in patients with transfusion-dependent beta-thalassemia major. Sixty-four patients (28 men, 36 women; mean age, 26.49 +/- 5.8 years) were enrolled in the study. The 3 groups were based on the chelation therapy received. The first group (19 patients) received deferiprone (DFP) (75 mg/kg per day orally), the second group (23 patients) received deferoxamine (DFO) (30-50 mg/kg per day subcutaneously at least 5 times/week), and the third group (22 patients) received a combination of DFO (30-50 mg/kg per day, 2-3 days/week) and DFP (75 mg/kg per day, 7 days/week). MRI scans were acquired with an imager equipped with a 1.5 T magnet, and the data included myocardial and hepatic iron measurements obtained by means of T2*, and ventricular volumes and ejection fractions obtained with standard cardiovascular MRI techniques. The results revealed that the DFP and the combined groups had significantly less myocardial iron than the DFO group (mean myocardial T2*, 35.77 +/- 18.3 milliseconds and 38.05 +/- 15.3 milliseconds versus 23.77 +/- 13 milliseconds [P = .02, and P = .001], respectively). On the contrary, the DFP group had a significantly higher hepatic iron content than the DFO and combined groups (mean hepatic T2*, 3.29 +/- 2.5 milliseconds versus 8.16 +/- 8.4 milliseconds and 11.3 +/- 10.9 milliseconds [P = .014, and P = .003], respectively). No correlation was observed between myocardial T2* and hepatic T2* values (r = -0.043; P = .37). Myocardial T2* values were inversely correlated with age (r = -0.249; P = .024) and positively correlated with both left and right ventricular ejection fractions (r = 0.33 [P = .004], and r = 0.279 [P = .014], respectively). Finally, liver T2* was strongly and inversely correlated with serum ferritin concentration (r = -0.465; P = .001). In conclusion, combined

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

    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

    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

    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

    An estimated 170 million persons (3% of the world's population) are infected with the hepatitis C virus (HCV), and 3 to 4 million persons are newly infected each year. Of those infected, 70%-85% develop chronic viremia with the potential for devastating long-term sequelae, including chronic liver disease, cirrhosis, hepatic failure, and hepatocellular carcinoma. The passivity in the public health sector and in the medical community at large with respect to hepatitis C portends a myriad of societal, fiscal, and personal costs for the United States within the next two decades unless immediate actions are taken to intervene in the natural history of this emerging public health crisis.

    2014-07-01

    For patients with acute venous thromboembolism treated with warfarin, parenteral anticoagulation should be continued for a minimum of 5 days and until the international normalized ratio (INR) is 2 or greater for at least 24 hours. Early initiation of warfarin therapy is recommended. The goal therapeutic INR range for patients treated with warfarin is most commonly 2 to 3. During maintenance warfarin therapy, validated decision-support tools should be used to guide dosing. For patients with stable INRs, frequency of INR testing can be extended from every 4 weeks to up to 12 weeks. Self-testing and self-management can be safe options for patients receiving warfarin who are motivated and show competence. Patients starting anticoagulation therapy should receive education on treatment goals, adverse effects, and monitoring strategy. Physicians deciding whether to prescribe one of the new oral anticoagulants instead of warfarin should assess for possible drug interactions and for renal and hepatic impairment and should consider the financial cost to the patient. No routine coagulation assay monitoring is required for patients receiving apixaban, dabigatran, or rivaroxaban. Physicians who oversee oral anticoagulation therapy should do so in a systematic and coordinated fashion.

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

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

    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.

    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.

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

    Hepatic sarcoidosis is usually asymptomatic but rarely leads to adverse liver-related outcome. Co-existence of viral hepatitis and hepatic sarcoidosis is a rare, but recognised phenomenon. Obtaining a balance between immune suppression and anti-viral therapy may be problematic. Immunosuppression in the presence of viral hepatitis can lead to rapid deterioration of liver disease. Similarly, anti-viral therapy may exacerbate granulomatous hepatitis. Here we present two cases of viral hepatitis co-existing with sarcoidosis that illustrate successful management strategies. In one, hepatitis B replication was suppressed with oral anti-viral therapy before commencing prednisolone. In the second, remission of hepatic sarcoidosis was achieved with prednisolone, before treating hepatitis C and obtaining a sustained virological response with pegylated interferon and ribavirin therapy.

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

    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.

    OBJECTIVE Although treatment of hepatitis C has improved, up to 50% do not respond to standard therapy with interferon regimes or cannot tolerate the treatment due to side effects. The purpose of the present investigation was to evaluate the safety and effectiveness of the antiviral drug amantadine for the treatment of hepatitis C in those who had either previously failed interferon therapy or were not candidates for interferon. DESIGN A prospective double-blind randomized placebo-controlled trial. SETTING Outpatient research clinic of a teaching hospital. PATIENTS/PARTICIPANTS One hundred fifty-two patients with confirmed hepatitis C with abnormal liver enzymes, detectable hepatitis C RNA in the blood, and abnormal liver histology by biopsy were randomized to receive treatment or placebo. MEASUREMENTS AND MAIN RESULTS Patients received either amantadine 100 mg twice daily by mouth or placebo for 6 months. After 6 months, placebo-treated patients were crossed over and treated with amantadine for 6 months and amantadine-treated subjects received 6 additional months of therapy. Amantadine therapy resulted in a significant decline in serum alanine aminotransferase compared to placebo (P = .03). Nine percent cleared the virus at the end of therapy and 6.8% had a sustained virologic response 6 months after discontinuation of amantadine, but this was not statistically significant. Side effects were minimal, and the social quality of life survey improved with 12 months of amantadine (P = .02). CONCLUSIONS Oral amantadine may provide a safe alternative treatment for those patients who are intolerant or unresponsive to interferon. PMID:15209605

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

    Background: Hepatitis B virus (HBV) has been classified into ten genotypes (A-J) based on genome sequence divergence, which is very important for etiological and clinical investigations. HBV genotypes have distinct geographical distributions worldwide. Objectives: The aim of this study was to investigate the distribution of HBV genotypes among Azerbaijani patients with chronic hepatitis B, came from the Republic of Azerbaijan country to Iran to receive medical care. Patients and Methods: One hundred and three patients with chronic HBV infection, referred to hospitals related to Iran University of Medical Sciences and Tehran Hepatitis Center from August 2011 to July 2014, were enrolled in this cross sectional study. About 3-milliliter of peripheral blood was taken from each patient. After viral DNA extraction, HBV genotypes were tested using the INNO-LiPA™ HBV kit (Innogenetics, Ghent, Belgium). HBV genotyping was confirmed using sequencing of hepatitis B surface antigen (HBsAg) and polymerase (pol) regions of HBV. Results: The mean age of patients was 35.9 ± 11.7 years (19-66). Of 103 patients, 72 (69.9%) were male. In the present study, the predominant HBV genotype was D (93.2%) followed by genotype A (5.8%) and concurrent infection with A and D genotypes (0.97%). Conclusions: The main and frequent HBV genotype among Azerbaijani patients with chronic hepatitis B virus infection was genotype D followed by genotype A. PMID:25685166

    2014-09-01

    We sought to describe the cardiovascular profile of veteran men before beginning androgen deprivation therapy (ADT), with the eventual benefit of targeting treatments to manage harmful cardiovascular side effects. We performed a secondary analysis with chi-square and Fisher's exact tests for associations between demographics and cardiovascular comorbidities on 375 veteran men diagnosed with prostate cancer. Those who were overweight and current smokers were more likely to be younger, whereas men with a systolic blood pressure >120 mmHg were more likely to be older (all P < 0.05). Men with total cholesterol 180 mg/dL were more likely to be identified in the Hispanic/other/unknown ethnicity category. Interventions to manage cardiovascular risk should focus on preventive lifestyle changes for younger men, and chronic disease management for older men. Men in the smaller Hispanic/other/unknown category are at risk for marginalization within the Veteran Administration system owing to their low numbers and should be closely monitored for cholesterol levels when receiving ADT.

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

    2011-01-01

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

    Little is known about the factors associated with patient compliance with nucleos(t)ide analog (NUC) treatment for chronic hepatitis B (CHB). The purpose of this study was to examine the association between sociodemographic and clinical characteristics and adherence to NUCs among patients with CHB. A total of 211 CHB patients receiving NUC monotherapy were asked to report the number of prescribed doses of medication they had taken during the last 90 days. A total of four 3-month adherence scores were averaged to obtain a combined rate of NUC adherence during a 1-year follow up period. The mean age of the patients was 29.6 years, 79% were men, and 68% had no prior NUC treatment for CHB. Females, patients without a previous NUC treatment, and those who had NUC drug resistance showed better adherence to NUC treatment, and compliance was better with telbivudine than with lamivudine and entecavir.

  11. Digital Receiver Phase Meter

    NASA Technical Reports Server (NTRS)

    Marcin, Martin; Abramovici, Alexander

    2008-01-01

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

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

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

    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.

    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.

  17. Metabolic actions of insulin in men and women

    Magkos, Faidon; Wang, Xuewen; Mittendorfer, Bettina

    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

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

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

    A predominantly heterosexual sample of 204 college men were asked to report incidents of pressured or forced sexual touch or intercourse since age 16. About 34% indicated they had received coercive sexual contact: 24% from women, 4% from men, and 6% from both sexes. Contact involved only sexual touching for 12% and intercourse for 22%. Sexual contact was pressured in 88% of the 81 reported incidents by tactics of persuasion, intoxication, threat of love withdrawal, and bribery. In 12% of the incidents, sexual contact was forced through physical restraint, physical intimidation, threat of harm, or harm. Contact was initiated by an acquaintance or intimate in 77% of incidents. The negative emotional impact of male contact was rated significantly higher than the impact of female contact. Men with and without coercion experience did not differ, however, for scale scores on sexual esteem, depression, and preoccupation. Interviews with 10 subjects revealed complex reactions to coercive male and female contact, including doubts about one's sexuality, resentment of unexpected or forceful contact, and fear of telling others about the event.

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.

    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.

    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.

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

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

    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.

    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

    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.

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

    Six of 106 undertakers (5.6%) gave a past history of hepatitis during their professional careers; this was no different from the frequency in a control group of 3,162 accountants (5.1%) who had no direct contact with blood. None of the undertakers or 210 blood donors matched for age, sex, and ethnic background had serum positive for hepatitis B surface antigen. Five undertakers (4.7%) had blood that was positive for antibody to hepatitis B surface antigen, compared with six of 210 (2.9%) in the control group; this difference was not statistically significant (P greater than .25). Thus, undertakers appear to be in a low-risk occupation with reference to acquisition of hepatitis B. Although the numbers are too small for statistical analysis, there appeared to be an increased exposure to hepatitis B in undertakers who take no preventive precautions. We recommend that the minimal precautions for undertakers be the wearing of gloves. PMID:660831

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

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

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

    An 80-year-old woman was referred for the surgical treatment of a 110-mm right hepatic tumor. The biopsy revealed an adenoma, and a right hepatectomy was performed. Histopathology indicated a major fat component with epitheliod cells, immunoreactivity for HMB45, Melan A, and smooth muscle actin, describing a hepatic epithelioid angiomyolipoma (AML). The AML belongs to the group of tumors with a Perivascular Epithelioid Cell differentiation. Its diagnosis is based on imaging and biopsy, and therefore might be difficult. Hepatic AML are mainly benign tumors; however, some tend to behave in a malignant manner. In case of histological proof, close clinical and radiological monitoring can be proposed if its size is less than 5 cm and no pejorative histological features are found. Nevertheless, follow-up is still required if resection is performed in search of recurrence or metastatic spread. PMID:25073214

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

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

    Background/Aims Clear indicators for stopping antiviral therapy in chronic hepatitis B (CHB) patients are not yet available. Since the level of hepatitis B surface antigen (HBsAg) is correlated with covalently closed circular DNA, the HBsAg titer might be a good indicator of the off-treatment response. This study aimed to determine the relationship between the HBsAg titer and the entecavir (ETV) off-treatment response. Methods This study analyzed 44 consecutive CHB patients (age, 44.6±11.4 years, mean±SD; men, 63.6%; positive hepatitis B envelope antigen (HBeAg) at baseline, 56.8%; HBV DNA level, 6.8±1.3 log10 IU/mL) treated with ETV for a sufficient duration and in whom treatment was discontinued after HBsAg levels were measured. A virological relapse was defined as an increase in serum HBV DNA level of >2000 IU/mL, and a clinical relapse was defined as a virological relapse with a biochemical flare, defined as an increase in the serum alanine aminotransferase level of >2 × upper limit of normal. Results After stopping ETV, virological relapse and clinical relapse were observed in 32 and 24 patients, respectively, during 20.8±19.9 months of follow-up. The cumulative incidence rates of virological relapse were 36.2% and 66.2%, respectively, at 6 and 12 months, and those of clinical relapse were 14.3% and 42.3%. The off-treatment HBsAg level was an independent factor associated with clinical relapse (hazard ratio, 2.251; 95% confidence interval, 1.076–4.706; P=0.031). When patients were grouped according to off-treatment HBsAg levels, clinical relapse did not occur in patients with an off-treatment HBsAg level of ≤2 log10 IU/mL (n=5), while the incidence rates of clinical relapse at 12 months after off-treatment were 28.4% and 55.7% in patients with off-treatment HBsAg levels of >2 and ≤3 log10 IU/mL (n=11) and >3 log10 IU/mL (n=28), respectively. Conclusion The off-treatment HBsAg level is closely related to clinical relapse after treatment cessation. A

    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.

  13. Hepatitis B virus infection.

    Hepatitis B virus (HBV) infection is a worldwide health problem and may cause acute, fulminant, chronic hepatitis, liver cirrhosis, or hepatocelullar carcinoma (HCC). Infection with HBV in infancy or early childhood may lead to a high rate of persistent infection (25-90%), while the rates are lower if infection occurs during adulthood (5-10%). In most endemic areas, infection occurs mainly during early childhood and mother-to-infant transmission accounts for approximately 50% of the chronic infection cases. Hepatitis B during pregnancy does not increase maternal mortality or morbidity or the risk of fetal complications. Approximately 90% of the infants of HBsAg carrier mothers with positive hepatitis B e-antigen (HBeAg) will become carriers if no immunoprophylaxis is given. Transplacental HBeAg may induce a specific non-responsiveness of helper T cells and HBcAg. Spontaneous HBeAg seroconversion to anti-HBe may develop with time but liver damage may occur during the process of the immune clearance of HBV and HBeAg. Mother-to-infant transmission of HBV from HBeAg negative but HBsAg positive mothers is the most important cause of acute or fulminant hepatitis B in infancy. Although antiviral agents are available to treat and avoid the complications of chronic hepatitis B, prevention of HBV infection is the best way for control. Screening for maternal HBsAg with/without HBeAg, followed by three to four doses of HBV vaccine in infancy and hepatitis B immunoglobulin (HBIG) within 24h of birth is the most effective way to prevent HBV infection. In areas with a low prevalence of HBV infection or with limited resources, omitting maternal screening but giving three doses of HBV vaccine universally in infancy can also produce good protective efficacy. The first universal HBV immunisation programme in the world was launched in Taiwan 22 years ago. HBV infection rates, chronicity rates, incidence of HCC and incidence of fulminant hepatitis in children have been effectively

    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

    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.

    In recent years, fathers' experiences during childbirth have attracted much research and policy interest. However, little of this work has been grounded in the first-hand accounts of men and there is a lack of theory-based research to help understand men's thoughts and practices around childbirth. This paper is based on qualitative research undertaken with first-time fathers and healthcare professionals. It draws on Connell's (1995) conceptualisation of hegemonic masculinity to explore how men construct masculine identities within the context of pregnancy and childbirth and also how healthcare professionals construct masculinity. The paper demonstrates the ways in which men can find themselves marginalised within the context of pregnancy and childbirth, but are still able to draw on identifiable markers of masculine practice which enable them to enact a masculine form congruent with dominant masculinity. It also illustrates how healthcare professionals' constructions of masculinity enable them to predict how men will behave and allow them to position men in ways that involve minimum disruption to their own practice. The paper also highlights how men's marginal status is embedded in the dynamics of the social structure, which produce and reproduce dominant masculine identities within the context of childbirth.

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

    Splanchnic metabolism was studied in the fed state during prolonged intravenous administration (30 g/h) of either fructose or glucose to hypertriglyceridemic men who had been maintained on a high-carbohydrate diet for 2 wk. Splanchnic exchange of amino acids and carbohydrates was quantified by measurement of splanchnic flow and of blood or plasma arteriohepatic venous concentration gradients. Results obtained in subjects receiving fructose were compared with those obtained in (a) similar subjects receiving glucose and (b) postabsorptive controls maintained on isocaloric, balanced diets. Mean arterial plasma levels of alanine, glycine, serine, threonine, methionine, proline, valine, leucine, histidine, lysine, and ornithine were significantly higher in subjects given fructose than in those give glucose (P less than 0.05). The mean arterial concentration and splanchnic uptake of alanine were significantly higher in subjects given fructose than in postabsorptive controls, despite a significantly lower fractional extraction of alanine in the former (P less than 0.05). The mean arterial plasma levels of serine and ornithine were significantly lower in subjects receiving fructose than in postabsorptive controls (P less than 0.05). About half of the administered fructose or glucose was taken up in the splanchnic region, where approximately 15% was converted to CO2 and 10% to lactate. Half of the fructose taken up in the splanchnic region was converted to glucose released from the liver. The amount of hexose carbon remaining for hepatic synthesis of liquids in subjects given fructose was less than half of that of subjects given glucose. These studies demonstrate that fructose and glucose have divergent effects on amino acid metabolism and that during hypercaloric infusion of glucose (as with fructose), the human liver is a major site of lactate production.

    Hepatitis B virus (HBV) and hepatitis C virus (HCV) are the major viruses known to cause viral hepatitis. Serological markers are commonly used as diagnostic and/or prognostic indicators of acute or chronic HBV or HCV infection. The ability to detect HBV DNA in serum has been reported to have prognostic value for the outcome of chronic HBV infection. A rapid and sustained drop in HBV DNA or HCV RNA levels in patients under therapy has been shown to be a predictive factor for a favourable treatment outcome. Various techniques for detecting HBV DNA or HCV RNA have already been described; however, there are various problems with the sensitivity or detection range of those methods. New virus measuring methods have recently been reported and used. The Cobas Taq Man HCV Test is a new method to detect HBV DNA and HCV RNA with higher sensitivity and a broader range of quantitation than conventional methods. Some reports have shown that these methods improve therapy monitoring and the management of HBV or HCV infection. Moreover, hepatitis E virus (HEV) infection has been reported in Japan. The clinical features and viral markers of HEV have also been described. PMID:19086457

    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.

    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.

    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

Hepatitis B virus does not seem to be directly cytopathic and the disease is known to be modulated largely by the host's immune response. Experience with immunosuppressant and immunostimulant drugs and a wide variety of antiviral agents, however, has indicated that none of these are of any benefit in patients with chronic hepatitis B, with the possible exception of adenine arabinoside. In view of the much more recent identification of the hepatitis C virus, studies of therapy for chronic hepatitis C are inevitably less extensive. A pilot study using acyclovir in patients with chronic non-A, non-B hepatitis did not show any benefit, although the treatment period may have been too short for the results to be conclusive. The only agent other than alpha interferon to be tried in chronic hepatitis C is ribavirin, which may have some activity. Many of the agents studied in chronic hepatitis B should also be investigated for the treatment of patients with chronic hepatitis C. PMID:8314494

    Utilization of hepatitis C seropositive kidney donors remains controversial. We examined the use of hepatitis C seropositive donors for renal transplantation. Data for creatinine, liver function tests, cold ischemia time, and graft and patient survival were analyzed from 20 hepatitis C seropositive recipients receiving cadaveric renal allografts from seropositive donors and were compared with 20 hepatitis C seropositive recipients receiving allografts from seronegative donors. Recipients receiving a kidney from a hepatitis C seropositive donor were on the waitlist for 9.9 +/- 1.8 months, compared with 17.8 +/- 3.3 months for those receiving a kidney from a seronegative donor (p < 0.05). There were no significant differences in graft or patient survival. Incidences of acute cellular rejection and acute tubular necrosis were similar. There were no significant differences in creatinine, alanine aminotransferase, alkaline phosphatase, or bilirubin values. While there was a significant difference in aspartate aminotransferase at 2 wk and 6 months, these differences were of questionable clinical importance. In conclusion, donor seropositivity for hepatitis C should not preclude renal transplantation into a hepatitis C seropositive recipient and utilization of these organs decreases waitlist time for hepatitis C seropositive recipients.

    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

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

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

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

    Background and aims Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are a serious global public health problem affecting billions of people. A population based serological survey was conducted in Uttarakhand, India to determine the prevalence and risk factors of HBV and HCV infections. Methods A cross-sectional study was conducted to achieve the primary objective of estimating the prevalence of HBsAg and anti-HCV seropositivity and to estimate the potential risk factors. Results A total of 495 volunteers completed the study questionnaire and underwent blood tests for HBsAg and anti-HCV serology. Of these, 339 (68.5%) were males and 156 (31.5%) were females. The mean age of the volunteers was 31 ± 4 years. The overall infection rate was 4.4% (n = 22) in the studied population. The seroprevalence of HBsAg was found to be 2.8% (n = 14) and of anti-HCV antibodies 1.8% (n = 9), whereas dual infection i.e. HBV and HCV infection was seen in 0.2% (n = 1). The overall analysis of risk factors of our data showed that persons who have received multiple blood transfusions, history of hepatitis among family members, visits to unregistered medical practitioners and uneducated people are at more risk for acquiring hepatitis B and hepatitis C infection. Conclusions The results indicate an intermediate level of endemicity of HBV and HCV infection in this geographical area of Uttarakhand. Some independent risk factors like blood transfusion, intra familial transmission, and visit to unregistered practitioners were identified. PMID:25755517

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

    The investigation has revealed that mixed hepatitis A + B is a genetically determined disease. HLA-A10, B21, Cw2, Cw5, A10-A19, B8-B13, B21-B35, A3-B21, and A9-B21 are immunogenetic markers of this disease. The carriers of HLA-B21, Cw5, A3-B21, and A9-B21 and those of HLA-A10, A10-A19, and A10-B14 are at high risk for this infection among men and women, respectively. The findings of the distribution of HLA antigens and their combinations in mixed infection with hepatitis A and B viruses allow prediction of its occurrence (including the consideration of examinees' gender) which will assist in solving the matter of timely prophylaxis of this pathology.

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

    Background The prevalence of newly-diagnosed cases of chronic hepatitis is decisive for the overall incidence rate of hepatitis B observed in Poland. Objectives We aimed to determine the chronic hepatitis B incidence trends in Poland, taking into consideration the ages, genders, and environments of the patients. Methods The study is based on aggregated data from Polish descriptive epidemiological studies for the period of 2005 to 2013 (i.e., hepatitis B incidence numbers and ratios, including mixed HBV and HCV infections) as published in the annual bulletins Choroby zakazne i zatrucia w Polsce (Infectious diseases and poisonings in Poland] drawn up by the laboratory for the monitoring and analysis of epidemiological status of the department of epidemiology at the national institute of public health - national institute of hygiene (NIPH-NIH). Poland, a central European country situated in the humid continental climate zone, is classified as a highly developed country. In the analyzed period, the Polish population consisted of about 38 million people, more than 19 million of whom were women, and more than 18 million of whom were men. Among European countries, Poland has the smallest number of national and ethnic minorities. For the purposes of epidemiological supervision, a special definition of acute hepatitis B was adopted in Poland in 2005, which facilitated separate registration of acute and chronic cases. Results A significantly increasing chronic hepatitis B incidence trend was observed in the population of Poland, with considerable increases in incidence rates for both men and women alike. The incidence rates for inhabitants of both urban and rural areas also showed an increasing tendency. Chronic hepatitis B occurred more frequently in men and in urban areas. For each of the five-year age groups encompassing patients between 20 and 54 years of age, the increase in the incidence rate proved to be significant. Conclusions The registered increase in the

    Due to their propensity for acting out with antisocial behaviours, angry men are often regarded as having antisocial personality disorder with little hope for treatment success. Whilst not denying the difficulties in working with angry men, this paper looks to challenge some of the received wisdom in this area. Antisocial personality disorder is compared with borderline personality disorder and the many similarities, including the association with childhood trauma, course of illness, symptoms and rates of occurrence, are discussed. Differences between the two groups may be associated with the internalization or externalization of anger. Some issues related to bias in diagnosis are raised, as is the universal hopelessness implied in the literature related to treatment of antisocial personality disorder. Some issues related to engaging traditional men are discussed. In this paper the term 'traditional men' is used to describe men who value stoicism, self-reliance, strength, work, status and aggression highly whilst denying any vulnerability and exhibiting restricted emotionality. There is a need to reframe the diagnosis in order to recognize the associated behaviours as being an adult manifestation of complex childhood trauma. Further, there is a need for treatment directed towards altering ongoing patterns of retraumatization which characterize the lives of these men. A case study is included to demonstrate a number of the issues involved in working with angry men. These include issues of connection, boundaries, safety and utilization of the general practitioner in setting up a containing structure. The case study is used to illustrate that when issues of connection and anger containment are positively addressed, good therapeutic outcomes are possible.

    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.

    Hepatic encephalopathy is a reversible progressive neuropsychiatric disorder that encompasses a wide clinical spectrum. Covert hepatic encephalopathy is defined as patients with minimal hepatic encephalopathy and Grade I encephalopathy by West-Haven Criteria. Terminology such as “sub-clinical”, “latent”, and “minimal” appear to trivialize the disease and have been replaced by the term covert. The lack of clinical signs means that covert hepatic encephalopathy is rarely recognized or treated outside of clinical trials with options for therapy based on patients with episodic hepatic encephalopathy. This review discusses the current available options for therapy in covert hepatic encephalopathy and focuses on non-absorbable disacharides (lactulose or lactitol), antibiotics (rifaximin), probiotics/synbiotics and l-ornithine-l-aspartate.

    Schwannoma is predominantly a benign neoplasm of the Schwann cells in the neural sheath of the peripheral nerves. Occurrence of schwannoma in parenchymatous organs, such as liver, is extremely rare. A 64-year-old man without neurofibromatosis was observed to have a space-occupying lesion of 23mm diameter in the liver during follow-up examination for a previously resected gastrointestinal stromal tumor (GIST) in the small intestine. He underwent lateral segmentectomy of the liver under a provisional diagnosis of hepatic metastatic recurrence of the GIST. Histological examination confirmed the diagnosis of a benign schwannoma, confirmed by characteristic pathological findings and positive immunoreactions with the neurogenic marker S-100 protein, but negative for c-kit, or CD34. The tumor was the smallest among the reported cases. When the primary hepatic schwannoma is small in size, preoperative clinical diagnosis is difficult. Therefore, this disease should be listed as differential diagnosis for liver tumor with clinically benign characteristics. PMID:22530081

  11. Gut microbiota and hepatic encephalopathy.

    PubMed

    Dhiman, Radha K

    2013-06-01

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

    There is a strong interest in the submillimeter astronomy community to increase the IF bandwidth of SIS receivers in order to better facilitate broad spectral linewidth and continuum observations of extragalactic sources. However, with an increase in receiver IF bandwidth there is a decrease in the mixer stability. This in turn effects the integration efficiency and quality of the measurement. In order to better understand the noise mechanisms responsible for reducing the receiver stability, we employed a technique first described by D.W. Allan and later elaborated upon by Schieder et al. In this paper we address a variety of factors that degrade the noise stability of SIS receivers. The goal of this exercise is to make recommendations aimed at maximizing SIS receiver stability.

    1983-12-15

    In a patient with the clinical features of classic ulceroglandular tularemia a solitary hepatic abscess was found during an ultrasound examination. Hepatic tularemia has rarely been reported since the advent of specific therapy, which prevents the disease from reaching the disseminated state. This case, however, shows that the liver can be involved early in the course of tularemia. Increased serum levels of hepatic enzymes may be the only sign of such a complication.

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

  3. Pharmacoeconomics of hepatic encephalopathy.

    Neff, Guy

    2010-05-01

    Understanding and appreciating the science of pharmacoeconomics have become even more important for health care providers and insurers during the recent economic downturn. Evaluating the true costs of any disease is complex; both direct costs, such as costs of drug therapy and the provision of care, and indirect costs, such as lost earnings and reduced quality of life, must be taken into account. With chronic liver disease, the most recent data indicate that direct costs were more than $2 billion whereas indirect costs were more than $450 million. Hepatic encephalopathy, a common complication of chronic liver disease, contributes to this economic burden. Although patients' length of stay during hospitalization for hepatic encephalopathy decreased from almost 9 days to 6 days (and has remained stable over the past few years) from 1993 to 2007, hospitalization costs rose from $13,000 to $30,000/hospital stay. In addition, 22% of patients were discharged directly to nursing homes or rehabilitation centers, which increases total costs. When assessing therapy for hepatic encephalopathy, it is important to consider the total costs of the disease, not just treatment costs. Although more expensive on a daily basis than lactulose, rifaximin has been shown to reduce hospitalization rates, has a better adverse-effect profile, and increases patient compliance. One study found that rifaximin produced a cost savings/patient/year of more than $3000 over lactulose therapy. PMID:20412038

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

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

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

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

    1989-06-01

    In order to see if the term of "plasma cell hepatitis", dating back to the early sixties, is still valid as a morphological diagnosis for autoimmune chronic hepatitis (AICH), and to find out if the existence of several subgroups is reflected by histopathology, we investigated 26 patients with chronic hepatitis, who met the criteria of autoimmune hepatitis based on tests for antinuclear, anti-smooth muscle antibodies (SMA) and on immunoassays for liver-kidney-microsomal (LKM) antigen, liver membrane antigen (LMA), and soluble liver antigen (SLA). In our material autoimmune hepatitis represent the entire spectrum of chronic hepatitis with variable inflammatory activity ranging from chronic persistent hepatitis to severe inflammatory lesions in chronic active hepatitis with transition to cirrhosis. When compared to viral chronic hepatitis A and non-A, non-B, however, characteristic features can be evaluated consisting in broad hypocellular areas of collapse and microacinar transformation of hepatocytes with hydropic swelling being the predominant type of cell lesion. Eosinophilic clumping and acidophilic necrosis were insignificant. Plasma cells were not a constituent feature of AICH. From this histopathologic pattern it may be concluded that the disease seems to run a sluggish course in most patients, however, in few cases a dramatic development may determine the disease with fatal acute episodes which are terminated by death or fade into slow progression. The different subgroups could not be distinguished by histopathology.(ABSTRACT TRUNCATED AT 250 WORDS)

  10. Customizable Digital Receivers for Radar

    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.

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

    Introduction Radical resection of bile duct carcinoma may require resection of hepatic arteries. Preoperative segmental embolization of the hepatic artery for resection of hilar cholangiocarcinoma has been reported. We report a patient with bile duct carcinoma infiltrating the proper hepatic artery. Presentation of case A 66-year old male with jaundice was diagnosed with mid-distal bile duct carcinoma. A replaced left hepatic artery originated from the left gastric artery. Pylorus-preserving pancreaticoduodenectomy (PPPD) with combined resection of hepatic artery was planned. To promote the development of collateral blood flow after excision of the hepatic artery, preoperative segmental embolization of the proper hepatic artery was performed. The patient underwent PPPD with concurrent resection of the common hepatic, right hepatic, and middle hepatic arteries without arterial reconstruction. He received adjuvant chemotherapy with gemcitabine for six months and is alive three years after surgery without tumor recurrence. Discussion The growth of collateral vessels after selective embolization of the proper hepatic artery has been used for hilar lesions and bile duct lesions. Resection of the hepatic artery without the need for complex arterial reconstruction, allowing a radical resection, may have contributed to this patient's relatively unremarkable recovery and long-term survival. Retroperitoneal mobilization of the pancreatic head and duodenum must be limited as important collaterals may originate in that area. Conclusion Preoperative segmental embolization of the hepatic artery before PPPD for a patient with a replaced left hepatic artery encouraged the growth of collateral blood supply, allowing radical resection including the vessels and obviated the need for arterial reconstruction.

    The UN Population Fund contends that it is the need for family planning (FP) information and services instead of lack of interest that prevents men from participating more in FP. 3 pilot projects in Pakistan, Zimbabwe, and Colombia have acted on this belief. In geographically isolated Mardan, Pakistan, the all male Urban Community Developing Council (UCDC) started a community education project to involve men in FP. 5 UCDC member form 1 community educator team of which there are 60. The teams visit families in Mardan. In 1988, 1 team reported that some men in the households wanted a women to inform their wives about FP. Eventually UCDC located enough women free to be members on 40 teams. In 4 years, contraceptive prevalence among married couples rose from 9% to 21%. Initially the methods tended to be temporary methods but are now longer lasting methods (IUDs, sterilization, injectables, and even a few vasectomies). Other community groups donate about US$541/month to the project. In 1988, the Zimbabwean National Family Planning Council (ZNFPC) began its national education/male motivation project which included sending messages via popular radio soap opera, discussions, and leaflet distribution. The program reached many rural men since they tend to have radios. In 1 year, more men were taking part in decisions about FP (25-35%). ZNFPC has learned it needs to design 2 campaigns to promote condom use: 1 for single and 1 for married men. PROFAMILIA in Colombia began its 1st male clinic in 1985 in Bogota. By 1992, it had 8 male clinics. The key to its success is attractive clinics, low cost vasectomy, individualized care, wide range of services such as condom distribution and treatment of sexually transmitted diseases, and Saturday hours. Despite the 3 projects' successes, they face many obstacles that need to be addressed.

    We theoretically discuss sensitivity limitations of a THz receiver which is based on up-conversion of the THz radiation into optical domain using high quality factor crystalline whispering gallery mode resonators. We show that the sensitivity of the receiver operating in the nonlinear regime approaches the sensitivity of an ideal THz photon counter. Thermal noise of the counter can be substantially reduced because of transparency of the nonlinear material in the THz frequency range. We also show that the density of power fluctuations of the receiver operating in the linear regime is given by the THz shot noise.

On March 28, 2000, SmithKline Beecham Biologicals (Rixensart, Belgium) received approval from the Food and Drug Administration of a supplement to its hepatitis B license to include the manufacture of single-antigen, preservative-free hepatitis B vaccine (Engerix-B, pediatric/adolescent); distribution of this product has begun. A single-antigen, preservative-free hepatitis B vaccine (Recombivax HB, pediatric) from Merck Vaccine Division (West Point, Pennsylvania) had earlier received similar approval (1). A preservative-free Haemophilus influenzae type b (Hib)/hepatitis B combination vaccine (Comvax) from Merck Vaccine Division also is available. An adequate supply of preservative-free hepatitis B vaccine is available for all infant and childhood vaccinations. Thimerosal preservative-containing hepatitis B vaccines may continue to be used for vaccination of adolescents and adults as recommended (2).

    Older men are less likely than older women to receive depression treatment. Latino older men in particular have been found to have significantly lower rates of depression treatment than their white-non-Mexican (WNM) counterparts. Prior research has shown that men are less likely than women to express overt affect and/or report depression symptoms that may prompt primary care physicians' inquiry about depression. Previous studies have overlooked the idioms of distress common among older men. This study investigates: a) the range of idioms of distress that emerge in the narratives of depressed older men, and b) the use of these idioms among depressed WNM and Mexican-origin older men. The present report is based on qualitative data collected through the Men's Health and Aging Study (MeHAS), a mixed-method study of clinically depressed WNM and Mexican-origin older (65 and above) men recruited in primary care settings. Qualitative analysis of 77 interviews led to identification of idioms of distress and informed idiom categories. Study findings show that: a) both groups of men utilized a range of idioms of distress that met current DSM criteria for depression, b) both groups were also likely to utilize idioms that feel outside clinical depression criteria, and c) there were similarities as well as differences between WNM and Mexican-origin men. This study provides a larger vocabulary that clinicians might consider in recognizing depression and initiating depression care for older men from diverse ethnic backgrounds. This is important to improve depression care among older men in general and those of Mexican-origin in particular.

    INTRODUCTION In 2006, Singapore adopted the universal hepatitis B immunoglobulin (HBIg) policy. Since then, all infants of hepatitis B surface antigen (HBsAg)-positive mothers receive HBIg, irrespective of maternal hepatitis B e antigen (HBeAg) status. However, the benefits of HBIg for infants of HBeAg-negative mothers are unclear. We compared the vertical transmission rates among children of HBeAg-negative mothers who were given HBIg versus a retrospective cohort who were not given HBIg, to determine its protective effect. METHODS This observational study involved pregnant HBsAg-positive women seen at National University Hospital, Singapore, between June 2009 and December 2013. If the infants of these mothers completed the recommended vaccination schedule, they were recruited into the study, along with their older siblings. Serological testing for the children was performed three months after completion of the last dose of vaccine, and hepatitis B virus (HBV) surface gene sequencing was carried out if HBV DNA was detected. RESULTS A total of 111 infants and 47 siblings were recruited. 2 (1.5%) children were found to have vertical transmission despite receiving HBIg, while no incidences of vertical transmission were found among the historical controls who did not receive HBIg (p = 1.00). CONCLUSION The overall effectiveness of the hepatitis B vaccination programme for children of HBsAg-positive mothers was high, regardless of HBIg administration. The addition of HBIg did not appear to confer additional benefits, in terms of vertical transmission rate, among infants born to HBeAg-negative mothers. PMID:26778725

  5. Solar dynamic heat receiver technology

    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.

    Can ideology, as a widespread "expectation creator," impact economic decisions? In two studies we investigated the influence of the Benevolent Sexism (BS) ideology (which dictates that men should provide for passive and nurtured women) on women's economic decision-making. In Study 1, using a Dictator Game in which women decided how to share amounts of money with men, results of a Generalized Linear Mixed Model analysis show that higher endorsement of BS and contextual expectations of benevolence were associated with more very unequal offers. Similarly, in an Ultimatum Game in which women received monetary offers from men, Study 2's Generalized Linear Mixed Model's results revealed that BS led women to reject more very unequal offers. If women's endorsement of BS ideology and expectations of benevolence prove contrary to reality, they may strike back at men. These findings show that BS ideology creates expectations that shape male-female relationships in a way that could be prejudicial to men.

    Isolated hepatocyte studies demonstrated that leucine can be a precursor of ketone bodies. In this study we examine the relative contribution of leucine to hepatic ketogenesis in vivo. Three groups of conscious dogs with long-term indwelling catheters in the femoral artery, hepatic vein, and portal vein were studied. Group I (n = 3) animals were fasted overnight for 24 hours, and those in groups II and III (n = 4, each) were fasted for 62 to 68 hours (designated 3-day fast). Groups I and III received intravenous saline solution (0.9%) and served as controls. In group II selective acute insulin deficiency (SAID) was induced by a peripheral intravenous somatostatin (SRIF) infusion and intraportal glucagon (0.55 ng/body weight/min). Net hepatic production (NHP) of ketone bodies (kb) and leucine (leu) was measured by the arteriovenous difference technique. Hepatic conversion of leucine to ketone bodies was measured by continuous infusion of L-U-(/sup 14/C)-leucine and by determination of the appearance of (/sup 14/C)-ketone bodies across the liver. In the group fasted overnight NHPleu was 0.02 +/- 0.01 mumol/kg/min, a value not different from zero. NHPkb was 3.1 +/- 0.1 mumol/kg/min and hepatic conversion of leucine to ketone bodies accounted for 3.5% of NHPkb. Insulin deficiency after 3 day's fasting resulted in a near 70% increase in NHPleu (from basal values of 0.31 +/- 0.1 mumol/kg/min to 0.52 +/- 0.06 mumol/kg/min during SAID, p less than 0.01). NHPkb increased from 11.0 +/- 1.0 to 15.5 mumol/kg/min (p less than 0.05). The rate of leucine conversion to ketone bodies (L-C) increased from 1.1 +/- 0.25 to 2.4 +/- 0.3 mumol/kg/min (p less than 0.01) with SAID.

    In view of the role of both the de novo biosynthesis and receptor-mediated uptake of cholesterol for normal steroidogenesis, we evaluated whether extending the therapeutic dose of the hepatic hydroxymethyl glutaryl coenzyme A (HMG-CoA) reductase inhibitor, simvastatin, to 80 mg/d would affect adrenal and gonadal steroid synthesis in men with hypercholesterolemia. To evaluate this question, we enrolled men into a multicenter randomized, placebo-controlled study lasting 12 weeks. Men with serum low-density lipoprotein cholesterol (LDL-C) more than 145 mg/dL after 6 weeks of a lipid-lowering diet were randomized to 80 mg simvastatin or placebo. Half of the subjects were asked to undergo a 6-hour infusion of corticotropin (ACTH) to evaluate cortisol synthesis, and the entire cohort received a human chorionic gonadotropin (hCG) stimulation test to assess gonadal hormone secretion using pooled serum samples taken 15 minutes apart. A total of 81 men (age, 45 +/- 11 years; 93% Caucasian) with baseline serum LDL-C of 197 mg/dL (placebo, n = 39) and 184 mg/dL (simvastatin 80 mg, n = 42) completed the study. After 12 weeks, serum LDL-C, triglycerides, and high-density lipoprotein cholesterol (HDL-C) in the simvastatin group changed by -43%, -25%, and 8%, respectively (all P < .001). The basal cortisol level and the peak serum cortisol and area under the curve response to the 6-hour ACTH infusion were comparable between the two treatment groups at baseline and after 12 weeks. The pooled total testosterone level at baseline was 541 and 513 ng/dL in the placebo and simvastatin-treated groups, respectively, which declined to 536 +/- 20.5 ng/dL (-1.5%) and 474 +/- 30.4 ng/dL (-13.6%, P = .09) after treatment (mean +/- SD). The pooled free testosterone declined by 6.3% in the simvastatin group, versus a 4.9% increase in the placebo group (P = .588), while pooled bioavailable testosterone declined 10.2% in the simvastatin group and increased 1.4% in the placebo group (P = .035

    A variety of studies evidenced a relationship between drug use disorders and sexual dysfunction. In particular, heroin and opioid agonist medications to treat heroin dependence have been found to be associated with erectile dysfunction and reduced libido. Controversial findings also indicate the possibility of factors other than the pharmacological effects of opioid drugs concurring to sexual dysfunction. With the present study, we investigated the link between sexual dysfunction and long-term exposure to opioid receptor stimulation (heroin dependence, methadone maintenance treatment, methadone dosage), the potentially related hormonal changes reflecting hypothalamus-pituitary-gonadal axis function and prolactin (PRL) pituitary release, the role of adverse childhood experiences in the clinical history and the concomitant symptoms of comorbid mental health disorders in contributing to sexual problems. Forty male patients participating in a long-term methadone treatment program were included in the present study and compared with 40 healthy control subjects who never used drugs nor abused alcohol. All patients and controls were submitted to the Arizona Sexual Experiences Scale (ASEX), Child Experiences of Care and Abuse-Questionnaire (CECA-Q) and the Symptom Check List-90 Scale. A blood sample for testosterone and PRL assays was collected. Methadone dosages were recorded among heroin-dependent patients on maintenance treatment. Methadone patients scored significantly higher than controls on the 5-item rating ASEX scale, on CECA-Q and on Symptoms Check List 90 (SCL 90) scale. Testosterone plasma levels were significantly lower and PRL levels significantly higher in methadone patients with respect to the healthy control group. ASEX scores reflecting sexual dysfunction were directly and significantly correlated with CECA-Q neglect scores and SCL 90 psychiatric symptoms total score. The linear regression model, when applied only to addicted patients, showed that methadone dosages were not significantly correlated with sexual dysfunction scores except for 'erectile dysfunction', for which an inverse association was evidenced. Testosterone values showed a significant inverse correlation with ASEX sexual dysfunction scores, CECA-Q neglect scores and psychiatric symptom at SCL 90 among methadone patients. PRL levels were directly and significantly correlated with sexual dysfunction scores, psychiatric symptoms at SCL 90 and CECA-Q neglect scores. Both testosterone and PRL did not correlate with methadone dosages. The present findings appear to support the view of childhood adversities and comorbid psychiatric symptoms contributing to sexual dysfunction and related hormonal changes among methadone patients, challenging the assumption that attributes sexual problems entirely to the direct pharmacological effects of opioid agonist medications.

    To provide an update of the latest trends in epidemiology, clinical course, diagnostics, complications and treatment of auto immune hepatitis (AIH). A search of the MEDLINE database was performed using the search terms: "auto immune hepatitis", "clinical presentation", "symptoms", "signs", "diagnosis", "auto antibodies", "laboratory values", "serology", "histopathology", "histology", "genetics", "HLA genes", "non-HLA genes", "environment", "epidemiology", "prevalence", "incidence", "demographics", "complications", "HCC", "PBC", "PSC", "corticosteroid", "therapy", "treatment", "alternative treatment". English-language full-text articles and abstracts were considered. Articles included reviews, meta-analysis, prospective retrospective studies. No publication date restrictions were applied. AIH is an immune meditated progressive inflammatory liver disease that predominantly affects middle-aged females but may affect people of all ages. The clinical spectrum of AIH is wide, ranging from absent or mild symptoms to fulminant hepatic failure. The aetiology of AIH is still unknown, but is believed to occur as the consequence of an aberrant immune response towards an un-known trigger in a genetically susceptible host. In the absence of a gold standard, diagnosis is based on the combination of clinical, biochemical and histopathological criteria. Immunosuppressive treatment has been the cornerstone of treatment since the earliest description of the disease in 1950 by Waldenström. Such treatment is often successful at inducing remission and generally leads to normal life expectancy. Nevertheless, there remain significant areas of unmet aetiological a clinical needs including fundamental insight in disease pathogenesis, optimal therapy, duration of treatment and treatment alternatives in those patients unresponsive to standard treatment regimens.

    The infectious agent causing epidemic non-A, non-B hepatitis was identified in 1983 from a human challenge experiment. The novel hepatitis E virus (HEV) subsequently was cloned in 1990 and the genome sequenced. HEV transmission is highly endemic in Asia, the Middle East, and Africa. Fecal contamination of drinking water is the most common mode of spread. Although usually asymptomatic, HEV infection can cause fulminant hepatitis. Recent studies indicate that hepatitis E may be a zoonotic disease, with pigs and possibly rats serving as reservoirs for human infection. A recombinant HEV vaccine is currently in phase III clinical trials. The characterization of the major types of viral hepatitis during the last 20 years illustrates how modern genetic technology has revolutionized research in infectious diseases. Within less than two decades of the discovery of HEV, its epidemiology has been described, serologic tests have been developed, and a candidate vaccine has been evaluated in clinical trials.

    Hepatitis E virus (HEV) has a long military association being first discovered during the Soviet occupation of Afghanistan in the 1980s after an outbreak of unexplained hepatitis at a military camp. HEV is now endemic in the UK, and should be considered in all cases of jaundice. The prevalence is high in certain operational areas (28.5% in Afghanistan), and maintenance of integrity of food and water supplies together with scrupulous attention to environmental hygiene remains paramount. Pregnancy confers a much higher risk of fulminant hepatitis, with a mortality rate of up to 25%. Management is usually symptomatic, but ribavirin can be considered in non-pregnant patients with fulminant hepatitis. This narrative review examines the presentations and management of Hepatitis E in military populations. PMID:24109137

    In Brazil, approximately 130 new cases of hepatitis A per 100,000 inhabitants occur annually and 15% of the population has been in contact with hepatitis B virus. Portal hypertension causes hypersplenism and reduces T cell production, which may lead to less effective response to hepatitis vaccination. The objective of the study was to evaluate the response to hepatitis A and B vaccination in patients with portal hypertension secondary to chronic liver disease or portal vein thrombosis. Twenty-three patients (2 to 18 years) with portal hypertension seen at the Pediatric Hepatology Service of Hospital das Clínicas, Universidade Estadual de Campinas, between 1994 and 2006 were studied. Hepatitis A and B serology was tested in all patients. Patients who had not been vaccinated before their visits received the vaccines during the study period. Patients who had been vaccinated before but had negative anti-HB antibodies received a booster dose, and their serology was repeated Blood counts were performed in each patient to assess for immunosuppression. Eighteen patients received hepatitis A vaccine and all became positive for anti-HAV antibodies. All patients had received hepatitis B vaccine and 17 (73.9%) were anti-HBs positive at the time of the study The other 6 received a booster dose and became anti-HBs positive afterward. The anti-HBs-positive and -negative patients did not differ significantly in age, leukocytes, lymphocytes, or duration between the vaccination and positive serology. In this study, hepatitis A vaccines elicited a 100% response and hepatitis B vaccine conferred protection and induced an anamnestic response in pediatric patients with portal hypertension.

    HIV prevalence among Chinese men who have sex with men has rapidly increased in recent years. In this randomized, controlled study, we tested the feasibility and efficacy of motivational interviewing to reduce high-risk sexual behaviors among this population in Changsha, China. Eighty men who have sex with men were randomly assigned to either the intervention group, in which participants received a three-session motivational interviewing intervention over 4 weeks, or the control group, in which participants received usual counseling from peer educators. High-risk behavior indicators and HIV knowledge level were evaluated at baseline and 3 months after the intervention. Motivational interviewing significantly improved consistent anal condom use. However, there was no significant change in consistent condom use for oral sex or in the number of sexual partners over time. HIV knowledge scores improved equally in both groups. This study demonstrated that an intervention using motivational interviewing is feasible and results in increased condom use during anal sex for Chinese men who have sex with men. However, further work must be done to increase the use of condoms during oral sexual encounters.

    The exchange of semen, often referred to as "cum play," has featured in gay literature and may be a unique aspect of many gay men's sexual behavior. We investigated the prevalence of "cum play" and its context among 1153 HIV-negative and 147 HIV-positive Australian gay men in an online survey. Receptive cum play (partner ejaculating or rubbing his semen over participant's anus, or participant using partner's semen as lubricant) was reported by one in six HIV-negative and one quarter of HIV-positive men on the same occasion of protected anal intercourse with a casual partner (PAIC). HIV-negative men who engaged in receptive cum play during PAIC often believed that their partner was HIV seroconcordant and tended to trust that partner. They were also generally more optimistic about the likelihood of HIV transmission, and they often only used condoms at their partners' instigation. Cum play was not uncommon and highlights the narrowness (or danger) of focusing on condom use without considering the implications of broader sexual practices and their meaning for sexual health promotion. "Safe sex" for some gay and bisexual men does not necessarily mean consistent commitment to condom use or to avoiding semen exchange. Many feel confident in their knowledge of their partner's HIV serostatus and only use condoms with these partners at their partner's request. Their commitment to safe sex may not necessarily be compromised by their practice of cum play, but the extent to which this could represent a risk for HIV transmission depends on the reliability of their assessment of their partners' HIV serostatus.

    Introduction: Hepatitis B is the most prevalent type of viral hepatitis. Psychological reactions among patients with hepatitis B infection is considerably different and affects their decision about treating and following up the disease. The present study aims at explaining the psychological demonstrations experienced by these patients. Methods: In this qualitative study, a total of 18 patients with hepatitis B (8 women and 10 men) were selected by purposive sampling method. Data were collected by unstructured in-depth interviews during 2014-2015 in the medical centers of three cities in Iran. All interviews were recorded, typed and analyzed by the conventional content analysis approach. Results: By analyzing the data, the main theme including psychological instability, with three sub-themes were emerged: grief reaction (stupor, denial, anger and aggression), emotional challenges (worry and apprehension, contradiction with beliefs, fear of deprivation, fear of stigma, waiting for death and prognosis ambiguity) and inferiority complex (social withdrawal, sense of humiliation and embarrassment and sense of guilt and blame) were acquired. Conclusion: The findings indicate that patients with hepatitis B experience various psychological reactions that need to be controlled and managed by themselves or healthcare providers. Thus, implementation of health interventions with emphasis on psychological care to prevent problems and execution of educational and consultation programs about hepatitis especially by medical centers and mass media is seems necessary.

    (1) Among 3,100 persons immunized against yellow fever with virus and immune serum over a period of five years, 89 cases of jaundice have been traced.(2) The symptoms are those of a hepatitis and closely resemble those produced by common infective hepatic jaundice, cases of which have frequently been noted as occurring in the same areas.(3) The average period between the time of inoculation and the development of hepatitis is between two and three months.(4) Attention is directed to the occurrence of hepatitis in horses, usually two to three months after immunization against the viruses of horse sickness and equine encephalomyelitis, and also after the injection of horse serum containing antitoxins against Cl. welchii toxins. Similar symptoms were observed, though to a lesser extent, in normal horses.(5) The only factor common to the inoculated horses and men was the injection of homologous proteins, either in sera or in tissue extracts.(6) The only theories which at present explain the observed facts are that either (1) a hepatotoxic virus is introduced with the virus inoculum or that (2) two factors combine to induce the hepatitis (a) a hepatotoxic substance present in the homologous sera or tissue extract injected and (b) an infective agent which, in the case at least of human beings, is probably the causal agent of common infective hepatic jaundice.

    Chronic hepatitis C virus (HCV) infection affects over 170 million people worldwide and is a common cause for liver transplantation in Canada. The prevalence of HCV infection in the dialysis population is estimated to be 20% to 50%. Today, intravenous drug use remains the most common route of transmission. The risk of acquiring HCV infection in patients on long-term hemodialysis is expected to decrease because of the screening of blood products for HCV. The diagnostic tests for hepatitis C include anti-HCV, HCV RNA, serum ALT levels, and liver biopsy. Liver biopsy is the definitive diagnostic procedure. Of patients acutely infected with the virus 50% to 85% will become carriers. HCV infection progresses slowly and the minority of patients develop cirrhosis over 20 years. The risk of hepatocellular carcinoma is increased once cirrhosis is present. The current standard of treatment that employs interferon and ribavirin has its limitations and is not indicated for many patients groups, such as patients on long-term hemodialysis. Interferon monotherapy is possible but is poorly tolerated by patients on dialysis. Patient and family education, as well as counselling, are important in that patients infected with HCV should be partners with health care providers in the management of their disease. PMID:11785189

    Infection with hepatitis C virus (HCV) accounts for 40% of cases of chronic liver disease in the United States and is now the most common indication for liver transplantation. Estimates suggest that 4 million people (1.8%) of the American population are or have been infected with HCV. Currently, the treatment of choice for patients with chronic HCV infection is recombinant interferon alfa with ribavirin. Pegylated interferons are a promising new development, and in combination with ribavirin, they will rapidly become the standard of care. The goals of therapy are to slow disease progression, improve hepatic histology, reduce infectivity, and reduce the risk of hepatocellular carcinoma. Sustained virologic response, which generally implies the absence of viremia for 6 months or more following completion of therapy, is increasingly being regarded as a cure, with evidence of slowing or even regression of fibrosis on follow-up liver biopsy. A number of factors have been shown to be predictive of a sustained response, including viral genotype other than 1, low serum HCV RNA levels, absence of cirrhosis, younger age, female gender, and shorter duration of infection. Disease severity as assessed by liver biopsy, comorbidities, and possible contraindications to therapy should be weighed in the decision to begin treatment. Counseling patients regarding transmission, natural history, and drug and alcohol abstinence also should be included in management. Close monitoring should be done during treatment for side effects of interferon, including depression and bone marrow suppression. Hemolytic anemia is the major side effect of ribavirin.

    A novel technique and structure that maximizes the extraction of information from reference pulses for UWB-TR receivers is introduced. The scheme efficiently processes an incoming signal to suppress different types of UWB as well as non-UWB interference prior to signal detection. Such a method and system adds a feedback loop mechanism to enhance the signal-to-noise ratio of reference pulses in a conventional TR receiver. Moreover, sampling the second order statistical function such as, for example, the autocorrelation function (ACF) of the received signal and matching it to the ACF samples of the original pulses for each transmitted bit provides a more robust UWB communications method and system in the presence of channel distortions.

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

    Men are less likely than women to test for HIV and engage in HIV care and treatment. We conducted in-depth interviews with men participating in One Man Can (OMC) - a rights-based gender equality and health programme intervention conducted in rural Limpopo and Eastern Cape, South Africa - to explore masculinity-related barriers to HIV testing/care/treatment and how participation in OMC impacted on these. Men who participated in OMC reported an increased capability to overcome masculinity-related barriers to testing/care/treatment. They also reported increased ability to express vulnerability and discuss HIV openly with others, which led to greater willingness to be tested for HIV and receive HIV care and treatment for those who were living with HIV. Interventions that challenge masculine norms and promote gender equality (i.e. gender-transformative interventions) represent a promising new approach to address men's barriers to testing, care and treatment.

    Purpose Newly diagnosed HIV infections among men who have sex with men (MSM) are rising in many European countries. Surveillance tools must be tailored to the current state of the epidemic, and include decentralised prospective monitoring of HIV incidence and behavioural changes in key populations. In this scenario, an open prospective cohort study was assembled—The Lisbon Cohort of MSM—aiming to dynamically monitor the frequency of disease and its predictors. Participants The Lisbon Cohort of MSM is an ongoing observational prospective study conducted at a community-based voluntary HIV counselling and testing centre in Lisbon, Portugal (CheckpointLX). Men testing negative for HIV, aged 18 or over and reporting having had sex with men are invited to follow-up visits every 6 months. At each evaluation, a face-to-face interview using a structured questionnaire is conducted, and HIV and syphilis rapid tests are performed by trained peer counsellors. From April 2011 to February 2014, 3106 MSM were eligible to the cohort of whom 923 (29.7%) did not participate. The remaining 2183 (70.3%) MSM were enrolled and 804 had at least one follow-up evaluation, for a total of 893 person-years of observation. Future plans The study findings will be disseminated in peer-reviewed journals and presented at national and international conferences. The follow-up of this cohort of HIV-negative MSM will be a valuable tool for monitoring HIV incidence in a setting where limited prospective information existed. Moreover, it will allow for a deeper analytical approach to the study of population time trends and individual changes in risk factors that currently shape the HIV epidemic among MSM. PMID:25967995

  13. Organic Rankine cycle receiver development

    The selected receiver concept is a direct-heated, once-through, monotube boiler operated at supercritical pressure. The cavity is formed by a cylindrical copper shell and backwall, with stainless steel tubing brazed to the outside surface. This core is surrounded by lightweight refractory insulation, load-bearing struts, and an outer case. The aperture plate is made of copper to provide long life by conduction and reradiation of heat away from the aperture lip. The receiver thermal efficiency is estimated to be 97 percent at rated conditions (energy transferred to toluene divided by energy incident on aperture opening). Development of the core manufacturing and corrosion protection methods is complete.

    The new 4mm receiver (67--93 GHz) for the Robert C. Byrd Green Bank Telescope (GBT) was built to take advantage of the improved surface accuracy of the dish. The low frequency end of the 3mm atmospheric window is not available with ALMA (<84 GHz), and the sensitivity of the GBT is better than any other facility within this band. We discuss the design and performance of this new receiver for the GBT, and highlight the science opportunities available with the instrument.

    Concerns exist regarding orthotropic heart transplantation in hepatitis C virus (HCV) seropositive recipients. Thus, a national registry was accessed to evaluate early and late outcome in HCV seropositive recipients undergoing heart transplant. Retrospective analysis of the United Network for Organ Sharing registry (1991 to 2014) was performed to evaluate recipient profile and clinical outcome of patients with HCV seropositive (HCV +ve) and seronegative (HCV -ve). Adjusted results of early mortality and late survival were compared between cohorts. From 23,507 patients (mean age 52 years; 75% men), 481 (2%) were HCV +ve (mean age 52 years; 77% men). Annual proportion of HCV +ve recipients was comparable over the study period (range 1.3% to 2.7%; p = 0.2). The HCV +ve cohort had more African-American (22% vs 17%; p = 0.01), previous left ventricular assist device utilization (21% vs 14%; p <0.01) and more hepatitis B core Ag+ve recipients (17% vs 5%; p <0.01). However, both cohorts were comparable in terms of extracorporeal membrane oxygenator usage (p = 0.7), inotropic support (p = 0.2), intraaortic balloon pump (p = 0.7) support, serum creatinine (p = 0.7), and serum bilirubin (p = 0.7). Proportion of status 1A patients was similar (24% HCV + vs 21% HCV -); however, wait time for HCV +ve recipients were longer (mean 23 vs 19 days; p <0.01). Among donor variables, age (p = 0.8), hepatitis B status (p = 0.4), and Center for Diseases Control high-risk status (p = 0.9) were comparable in both cohorts. At a median follow-up of 4 years, 67% patients were alive, 28% died, and 1.1% were retransplanted (3.4% missing). Overall survival was worse in the HCV+ cohort (64.3% vs 72.9% and 43.2% vs 55% at 5 and 10 years; p <0.01), respectively. Late renal (odds ratio [OR] 1.2 [1 to 1.6]; p = 0.02) and liver dysfunction (odds ratio 4.5 [1.2 to 15.7]; p = 0.01) occurs more frequently in HCV +ve recipients. On adjusted analysis, HCV seropositivity is

    Humans are quite unusual compared to other great apes in that reproduction typically takes place within long-term, iteroparous pairings—social arrangements that have been culturally reified as the institution of marriage. With respect to male behaviour, explanations of marriage fall into two major schools of thought. One holds that marriage facilitates a sexual division of labour and paternal investment, both important to the rearing of offspring that are born helpless and remain dependent for remarkably long periods (provisioning model). And the other suggests that the main benefits which men receive from entering into marriage derive from monopolizing access to women's fertility (mating effort model). In this paper, we explore extramarital sexual relationships and the conditions under which they occur as a means of testing predictions derived from these two models. Using data on men's extramarital sexual relationships among Tsimane forager–horticulturists in lowland Bolivia, we tested whether infidelity was more common when men had less of an opportunity to invest in their children or when they risked losing less fertility. We found that Tsimane men appear to be biasing the timing of their affairs to when they are younger and have fewer children, supporting the provisioning model. PMID:17456459

  20. Testosterone and depression in aging men.

    In men, testosterone secretion affects neurobehavioral functions such as sexual arousal, aggression, emotional tone, and cognition. Beginning at approximately age 50, men secrete progressively lower amounts of testosterone; about 20% of men over age 60 have lower-than-normal levels. The psychiatric sequelae are poorly understood, yet there is evidence of an association with depressive symptoms. The authors reviewed 1) the physiology of the hypothalamic-pituitary-gonadal axis and its changes with age in men; and 2) the evidence linking testosterone level and major depression in men. Data on this relationship are derived from two types of studies: observational studies comparing testosterone levels and secretory patterns in depressed and non-depressed men, and treatment studies using exogenous androgens for male depression. The data suggest that some depressed older men may have state-dependent low testosterone levels and that some depressed men may improve with androgen treatment.
