Prognosis of PD-L1 in human breast cancer: protocol for a systematic review and meta-analysis.

Background: Breast cancer is one of the most common malignancies in women worldwide, and one of the leading causes of cancer-related death. Programmed cell death 1 (PD-1) and its ligand (PD-L1) are key physiologic suppressors of the cytotoxic immune reaction. Some authors advocate that PD-L1 expression may help in breast cancer prognosis.

A portrait of risk behavior towards HIV infection among Brazilian Army conscripts by geographic regions, 2016.

Introduction: Knowledge about risky sexual behavior among young people has been widely acknowledged as a key tool to controlling the spread of HIV. This article aimed at presenting the risk behavior of Brazilian Army conscripts toward HIV infection according to the country's geographic regions. .

Hepatitis B and C prevalence and risk factors among young men presenting to the Brazilian Army: A STROBE-compliant national survey-based cross-sectional observational study.

Viral hepatitis is caused by different etiological agents with distinct epidemiological, clinical, and laboratory characteristics accounting for significant worldwide morbidity and mortality. Since 1996, the Brazilian Department of Sexually Transmitted Infections (STIs), Acquired Immune Deficiency Syndrome (AIDS) and Viral Hepatitis (DIAHV) in collaboration with the Ministry of Defense has been conducting periodic serosurveys of conscripts enlisted for the Brazilian army to assess STI prevalence and obtain data on knowledge and risk factors pertaining to STIs. This article aims to present the hepatitis B (hepatitis B surface antigen - HBsAg) and C (anti-HCV) seroprevalence estimates and risk factors as per the 8th edition of the Conscript Survey performed in 2016.

This study aimed to estimate the HIV seroprevalence of conscripts in Brazil by geographic region and to describe behavior in relation to the risk of HIV transmission by analyzing data from the Brazilian Conscripts Survey 8th edition performed in 2016.Conscripts were selected with a 2-stage sampling method stratified by geographical region.

Accuracy of p57 compared with genotyping for the diagnosis of complete hydatidiform mole: protocol for a systematic review and meta-analysis.

Background: Distinguishing hydatidiform moles (HMs) from non-molar specimens and the subclassification of HM are important because complete hydatidiform mole (CHM) is associated with an increased risk of gestational trophoblastic neoplasia. However, diagnosis based solely on morphology has poor interobserver reproducibility. Recent studies have demonstrated that the use of p57 immunostaining improves diagnostic accuracy for CHM.
