Assessing the potential ecological and human health risks of trace metal pollution in surface water, sediment, and commercially valuable fish species in the Pashur River, Bangladesh.

This research examines the contamination levels in the Pashur River in Bangladesh stemming from trace metal discharge originating from the Mongla seaport and various industrial outlets. It delves into both ecological risks and potential health hazards for humans consuming fish carrying accumulated trace metals. The research employed atomic absorption spectrometry to measure the concentrations of chromium (Cr), arsenic (As), manganese (Mn), copper (Cu), zinc (Zn), nickel (Ni), lead (Pb), and cadmium (Cd) in surface water, sediment, and fish samples.

Awareness and willingness to use pre-exposure prophylaxis among the University of Zambia students: A cross-sectional study.

Background And Aims: Despite a quick rollout of PrEP as a preventive method against Human Immunodeficiency Virus (HIV) infections in Zambia, adolescent and young adult populations have remained very vulnerable to HIV infection. This study assessed the awareness and willingness to use PrEP among University of Zambia (UNZA) students.

Methods: Three hundred forty-six students participated in this cross-sectional study at UNZA between March and June 2021.

Manual Chest PRESSURE During Direct Current Cardioversion for Atrial Fibrillation: A Randomized Control Trial (PRESSURE-AF).

Background: Direct current cardioversion is frequently used to return patients with atrial fibrillation (AF) to sinus rhythm. Chest pressure during cardioversion may improve the efficacy of cardioversion through decreasing transthoracic impedance and increasing cardiac energy delivery.

Objectives: This study aimed to assess the efficacy and safety of upfront chest pressure during direct current cardioversion for AF with anterior-posterior pad positioning.

Microplastics occurrence in sea cucumbers and impacts on sea cucumbers & human health: A systematic review.

Microplastics (MPs) are a developing concern in marine environments, with scientists concentrating more on their effects on various creatures. Sea cucumbers (SCs), as suspension and deposit feeders, are expected to be exposed to and consume MPs in their habitat. The purpose of this methodical review is to gather and integrate accessible research on the presence and effects of MPs on SCs.

A comprehensive scenario of heavy metals pollution in the rivers of Bangladesh during the last two decades.

For decades, rivers have been used for transporting pollutants loaded with heavy metals (HMs) causing severe pollution in downstream. The current study aimed to review the levels and sources of 10 HMs, viz. As, Pb, Cd, Cr, Fe, Mn, Cu, Co, Ni, and Zn in the surface water of the rivers in Bangladesh.
