Hepatitis B has long been a serious public health problem in Greece. In recent years, a decline in hepatitis B infection is observed ascribable to many factors such as demographic and socioeconomic changes, medical precautions, use of disposable medical equipments, screening of blood donors and vaccination. We studied the prevalence of HBV infection in a sample of 1050 Greek male Navy recruits. 343 subjects (32.6%) had previously been vaccinated and were anti-HBs positive. We observed that during the last decade, the prevalence of immunes declined to 1.33% and the prevalence of any HBV marker declined to 2.28%. The HBsAg carrier rate declined from 3.9% in 1973 to 0.9% in 1986. Since then, it is stable at 0.95% because perinatal and vertical transmissions are still responsible for the majority of HBV chronic infections. Universal prenatal screening and infant immunization will contribute to a further decline of HBV infection.

Chronological changes in etiology, pathological and imaging findings in primary liver cancer from 2001 to 2020.
Jpn J Clin Oncol
January 2025
Department of Pathology, Keio University School of Medicine, Tokyo, Japan.
Purpose: To achieve a historical perspective, the chronological changes in primary liver cancer over a 20-year period were investigated at a single institution, focusing on shifts in etiology and the impact on imaging and pathological findings using The Liver Imaging Reporting and Data System.
Materials And Methods: A retrospective study of surgically resected primary liver cancer in 680 patients from 2001 to 2020 resulted in 434 patients with 482 nodules being analyzed. Dynamic contrast-enhanced computed tomography imaging and the Liver Imaging Reporting and Data System 2018 classification were employed.

Department of Maternal-Infant and Public Health Nursing, Ribeirão Preto College of Nursing, University of São Paulo, Ribeirão Preto 14040-902, São Paulo, Brazil.
Introduction: Vaccines are a significant public health achievement, which are crucial for child survival and disease control globally. In Brazil, the National Immunization Program (PNI) manages vaccination schedules, including essential vaccines like BCG and Hepatitis B, administered at birth. Despite achieving over 95% coverage for years, vaccination rates have declined since 2016, a trend exacerbated by the COVID-19 pandemic.

Background: Syphilis is a sexually transmitted infection (STI) that can be prevented and effectively treated; yet it continues to be a cause of morbidity and mortality worldwide. There is a limited understanding of the epidemiology of syphilis in the Middle East and North Africa (MENA) region.
Methods: A systematic review conducted up to April 30, 2024 assessed the prevalence of syphilis and followed PRISMA guidelines, without language and date restrictions.

Introduction: Gastrointestinal (GI) cancers account for over a quarter of all cancer-related deaths in the United States; however, the latest trends in their prevalence remain unclear.
Methods: Data on GI cancers were obtained from the Global Burden of Disease Study 2021. Age-standardized incidence rates (ASIR) and age-standardized mortality rates (ASMR) were estimated across various states, sexes, ages, and risk factors, and annual percentage changes were calculated.
Sarcopenia with muscle wasting in hepatic cancer predicts therapeutic outcome after hepatic artery intervention.
Int J Clin Pharmacol Ther
December 2024
Objectives: We aimed to study sarcopenia for its significance in predicting the effect of hepatic artery intervention (HAI) plus lenvatinib on hepatitis B-related hepatocellular carcinoma (HCC) complicated with diabetes mellitus (DM).
Materials And Methods: Hepatitis B-related HCC patients complicated with DM (n = 102) visiting during January 2021 and December 2023 were retrospectively selected. Computed tomography was performed to detect the third lumbar vertebra for its muscle cross-sectional area.
