25. Seroprevalence of Bartonella spp., Coxiella burnetii, and Hantavirus among people who inject drugs in Rio de Janeiro, Brazil: a retrospective assessment of a biobank
ABSTRACT The increasing use of illicit drugs imposes a public health challenge worldwide. People who inject drugs (PWID) are more susceptible to health complications due to immunosuppression associated with drug use and non-hygienic self-administration of substances, contaminants, and liquids. PWID are subjected to increased risk of acquiring and transmittin

26. Antiproliferative effect of urolithin A, the ellagic acid-derived colonic metabolite, on hepatocellular carcinoma HepG2.2.15 cells by targeting Lin28a/let-7a axis
An abnormality in the Lin28/let-7a axis is relevant to the progression of hepatitis B virus (HBV)-positive hepatocellular carcinoma (HCC), which could be a novel therapeutic target for this malignant tumor. The present study aimed to investigate the antiproliferative and anti-invasive effects of urolithin A in a stable full-length HBV gene integrated cell li

27. Making the invisible visible: searching for human T-cell lymphotropic virus types 1 and 2 (HTLV-1 and HTLV-2) in Brazilian patients with viral hepatitis B and C
With this study, the authors hope to alert clinicians regarding the presence of human T-cell lymphotropic virus type 1 and 2 (HTLV-1/-2) infections in patients with viral hepatitis B and C in Brazil. HTLV-1/-2 were detected in 1.3% of hepatitis B virus (HBV)- and 5.3% of hepatitis C virus (HCV)-infected blood samples sent for laboratory viral load measuremen

28. Avaliação da prevalência de transmissão vertical de hepatite B em duas gerações consecutivas
Resumo Introdução: A hepatite B é um importante problema de saúde pública no mundo e uma das formas de contágio seria através da transmissão vertical. O diagnóstico precoce possibilita a adoção de medidas de profilaxia, o que resulta na prevenção em mais de 90% dos casos. Objetivo: Descrever as prevalências de transmissão vertical e comparar

29. Detection of occult hepatitis B in serum and oral fluid samples
In occult hepatitis B infection (OBI), hepatitis B virus DNA (HBV DNA) can be detected in serum samples; however, oral fluid collection for detection of HBV DNA has not yet been explored, despite the availability of collection devices. Serum and oral fluid samples from 45 hepatitis B core antibody (anti-HBc)-positive patients were collected for the amplifica

30. Soroprevalência de hepatite B, hepatite C e vírus da imunodeficiência humana em pacientes submetidos a septoplastia
Resumo Introdução No mundo todo, os vírus da hepatite B (VHB), da hepatite C (VHC) e da imunodeficiência humana (HIV) são problemas de saúde importantes. Os profissionais de saúde correm o risco de contrair vírus transmitidos pelo sangue e os cirurgiões têm um maior risco de exposição ao sangue e taxas mais elevadas de lesões percutâneas do qu

31. Is waste collection associated with hepatitis B infection? A meta-analysis
Abstract This meta-analysis, which is based on a previously published systematic review, aims to contribute to the scientific discussion on hepatitis B virus (HBV) infection in workers who are exposed to domestic and healthcare wastes. Publications were sought which had been made available on the data used by December 2013 and updated to December 2016. The q

32. Association of polymorphisms in the heparanase gene (HPSE) with hepatocellular carcinoma in Chinese populations
Abstract Heparanase activity is involved in cancer growth and development in humans and single nucleotide polymorphisms (SNPs) in the heparanase gene (HPSE) have been shown to be associated with tumors. In this study, we investigated whether SNPs in HPSE were a risk factor for hepatocellular carcinoma (HCC) by undertaking a comprehensive haplotype-tagging, c

33. Identification of hepatitis B virus A1762T/G1764A double mutant strain in patients in Southern Brazil
Abstract Infection by hepatitis B virus (HBV) is a worldwide public health problem. Chronic HBV infection with high viral replication may lead to cirrhosis and/or hepatocellular carcinoma. Mutant HBV strains, such as the HBV A1762T/G1764A double mutant, have been associated with poor prognosis and higher risk of the patient for developing cirrhosis and/or he

34. Basal core promoter and precore mutations among hepatitis B virus circulating in Brazil and its association with severe forms of hepatic diseases
BACKGROUND In Brazil, few studies have investigated the prevalence of infection with the precore (PC) and basal core promoter (BCP) mutants of the hepatitis B virus (HBV). OBJECTIVES This study aimed to analyse the frequency of PC and BCP mutations among patients infected with HBV and to evaluate the association between the variants and advanced hepatic

No Brasil, existem poucos dados sobre a infecção por hepatite B entre pessoas em situação de rua, uma população marginalizada com alto risco para infecções sexualmente transmissíveis (IST), incluindo a hepatite B. O objetivo deste estudo foi investigar a epidemiologia da hepatite B em pessoas alojadas em um abrigo público da cidade de Goiânia, Bra

36. Prevalence of Hepatitis B and C virus infection among alcoholic individuals: importance of screening and vaccination
ABSTRACT Drug users have been reported to have an increased risk for acquisition of viral hepatitis. This study aims to evaluate the prevalence of HBV and HCV infection and usefulness of saliva for HBsAg and anti-HCV detection in alcoholic patients.A total of 90 alcoholic patients were recruited in 2013. HBsAg and anti-HCV were tested in serum and saliva, an
