Facilitators and Barriers to Pre-Exposure Prophylaxis Uptake Willingness for Full-Service Sex Workers: A Social-Ecological Approach.

Full-service sex workers (FSSWs) are at heightened risk of contracting HIV due to facing multi-level challenges to sexual health. This study investigated factors associated with willingness to use Pre-Exposure Prophylaxis (PrEP) - a daily HIV preventative medication, among FSSWs. Using social-ecological theory, an online survey was developed with initial guidance from a local sex worker advocacy organization to assess barriers and facilitators to PrEP uptake willingness.

Environmental and human health risk assessment of potentially toxic elements in rehabilitating iron mine lands in the Brazilian Amazon.

Waste pile substrates from Fe mining may carry potentially toxic elements (PTE). Rehabilitation efforts must maintain soil vegetation cover effectively, avoiding the dispersion of particulate matter and reducing the risk to the environment and human health. Therefore, this study aims to evaluate the pseudo-total and extractable contents, perform chemical fractionation, and assess the bioaccessibility and risk of PTE in waste piles of Fe mining in the Eastern Amazon.

Effects of Phytochemicals on Metabolic Diseases and Human Health.

Metabolic diseases constitute a worldwide health concern because of their increasing prevalence and associated mortality [...

Early Thrombocytopenia at Hospital Admission Predicts Mortality in Patients with Non-Isolated Severe Traumatic Brain Injury.

Unlabelled: Patients with severe traumatic brain injury (STBI) often experience an abnormal hemostasis that contributes to mortality and unfavorable neurological outcomes.

Objectives: We aimed to analyze epidemiologic, clinical, and laboratory factors associated with mortality in patients with STBI during the first 48 h after in-hospital admission.

Methods: We performed an observational retrospective study of STBI patients with associated extracranial trauma [defined as Injury Severity Score (ISS) ≥ 16 with an Abbreviated Injury Scale (AIS) head and neck ≥ 3 and Glasgow Coma Scale (GCS) ≤ 8] admitted to a Level II trauma center over seven years (2015-2021).

Mercury and selenium in biological pump under upwelling-downwelling influence in Cabo Frio shelf, South Atlantic Ocean, Brazil.

The knowledge of metals concentration in upwelling areas are a concern due the higher productivity of these areas In Cabo Frio Upwelling-Downwelling System (CFUS) is high primary productivity area and has been identified as an Hg hotspot to biota in SE Brazil that has been susceptible to Hg inputs, due to growing industrialization in the region. To investigate the concentration of Hg and Se metals, as well as the trophic transfer of these metals, the present study investigated Hg and Se concentrations in 64 samples collected in net mesh of >20, >64, >150 and >300 μm, in 2012, in the region's water masses. Higher mean Hg concentrations were found in zooplankton, 0.
