The marine environment is severely contaminated by anthropogenic activities. Among the pollutants are metals such as mercury (Hg), chromium (Cr), and zinc (Zn), elements commonly found in industrial effluents from steel mills. This study aims to quantify the concentrations of Hg, Cr, and Zn in seafood samples (crab and mussels) and conduct a consumption risk analysis, considering the seasonality and sexual dimorphism of the animals. The samples were collected from traditional fisheries in Itaipu, Niterói, Rio de Janeiro, Brazil. Muscle samples were removed from the animals, which served as the basis for determining Hg, Cr, and Zn levels. Consumption risk assessment was also conducted following the Estimated Monthly Intake and Hazard Quotient (HQ). The quantification results were below the limits set by international regulatory agencies. However, the risk analysis for the population revealed some HQ values above one, particularly for crab consumption.

Background: The aim of this was to develop an atrial fibrillation (AF) risk score using items usually included in Japanese governmental health check-ups.
Methods And Results: We analyzed data from 6,476 Japanese participants registered in the Suita Study. At baseline, the participants were aged ≥30 years and were free from AF.
Usefulness of an Intermittently Scanned Continuous Glucose Monitoring System for Risk Management of Individuals without Diabetes in Japan.

Department of Pharmacy, College of Pharmacy, Kinjo Gakuin University, 2-1723 Omori, Moriyama-ku, Nagoya 463-8521, Japan.
We examined whether the glucose levels and awareness of individuals without diabetes changed after using a sensor-based intermittently scanned continuous glucose monitoring (isCGM) system in their daily lives. Japanese individuals without a diabetes diagnosis wore the isCGM system while maintaining a normal lifestyle during the baseline period. A certified diabetes educator coached them on how to improve their lifestyle based on information from sensor data, food journals, and body composition.

BMJ Open
March 2025
Department of Preventive Medicine, Tokai University School of Medicine, Isehara, Japan.
Objectives: While there is growing evidence that physical activity reduces the risk of hepatocellular carcinoma (HCC), the impact of occupational physical activity and sedentary behaviour remains unclear. This study aimed to investigate the associations between occupational physical activity and sedentary behaviour and HCC risk.
Design: Matched case-control study.

Objectives: Iron deficiency anaemia and inadequate compliance with iron-folic acid (IFA) supplementation among pregnant and postpartum women pose substantial public health challenges in Nepal. Hence, this study aimed to determine IFA compliance and identify associated factors among postpartum mothers in Bharatpur Metropolitan City, Chitwan, Nepal.
Design: An analytical cross-sectional design was employed.
