AI Article Synopsis
- This study assessed dietary intake levels of various heavy metals and minerals among adults in Valdivia, Chile, using a 24-hour recall survey.
- The highest average daily intakes were reported for total arsenic, inorganic arsenic, cadmium, mercury, sodium, and potassium in individuals weighing 70 kg.
- While the carcinogenic risk from inorganic arsenic was considered low, overall sodium and potassium intakes raised health concerns, with sodium intake exceeding and potassium intake falling short of WHO recommendations.
Article Abstract
This study was designed to estimate the dietary intake of total arsenic, inorganic arsenic, cadmium, mercury, sodium, and potassium by the general adult population (aged 18-65) of Valdivia, Chile. Calculations were based on a 24-h dietary recall survey. The highest dietary intake of t-As (73.0 μg/day), i-As (20.0 μg/day), Cd (18.0 μg/day), Hg (5.8 μg/day), Na (3112.8 mg/day), and K (2077.5 mg/day) were for 70-kg adults. Estimating carcinogenic risk (CR > 4 × 10) due to exposure to i-As indicated that consumers remain at low risk for cancer. The cumulative health risk was evaluated by summing the target hazard quotient of cadmium (0.26) mercury (0.27) and inorganic arsenic (0.96); this calculation allows us to express the total target hazard quotient as 1.50 where a value > 1 indicates that there is a potential health risk for the population. Total intake of Cd and Hg were therefore within the limits estimated as being safe whereas Na and K intake for the Valdivia population did not follow the recommended values established by the World Health Organization (WHO). The Na intake exceeded the daily recommended intake while K intake was lower than the daily recommended intake. This indicates a health risk for the Valdivia population.

Introduction: Behaviour change interventions have the potential to improve sanitation and hygiene practices in urban settings. However, evidence on which behaviour change interventions have successfully improved sanitation and hygiene practices in urban settings is unclear.
Methods: We performed electronic searches across five databases and one grey literature database to identify relevant studies published between January 1, 1990 and November 20, 2023 in English.

While low dietary quality has been linked to poor mental health, evidence on more direct relations of specific dietary quality indicators, namely degrees of food processing, with mental health disorders remains limited. This study aims to investigate the association between food groups' intakes, defined based on their degree of food processing, with depression and anxiety symptoms in a sample of Lebanese adults. We hypothesized that higher intakes of ultra-processed foods (UPF) will be related to higher risk of depression and anxiety while an opposite association will be observed for unprocessed or minimally processed foods (MPF).

Health care workers are at risk of infection from aerosolization of respiratory secretions, droplet and contact spread. This has gained great importance after the COVID19 pandemic. Intra-operative aerosol-generating procedures are arguably unavoidable in the routine provision of thoracic anesthesia.

Since 2015, reductions in maternal mortality have stalled globally. In some parts of the world, severe maternal morbidity and mortality have increased, and most cases are thought to be from preventable causes. This is further exacerbated by significant racial, ethnic, and geographic disparities in maternal health outcomes, particularly among countries with diverse populations.
