Objective: We sought to test whether a 2-week Total Worker Health (TWH) training mapped to TWH education competencies could be administered to a Mexican audience of occupational safety and health professionals and could lead to positive changes to knowledge and behaviors.
Methods: This study used robust program evaluation methods collected before and after each of the nine training days and at the end of the course.
Results: Overall course quality received a mean score of 4.6 (SD = 0.6) and 98.8% of participants agreed that their TWH knowledge increased. All participants intended to make at least one change to their professional practice, most frequently helping companies assess their organizational culture to support health, safety, and well-being.
Conclusions: This TWH training was well received and led to positive self-reported increase in knowledge and abilities to influence workers' health, safety, and well-being.

Background: Workers in industry settings are often exposed to complex noise, which poses a greater risk to hearing loss than continuous noise at equivalent energy levels. Previous studies have identified kurtosis as an essential metric for evaluating complex noise-induced hearing loss (NIHL). This study aimed to characterize the distribution of workers exposed to complex noise, examine the associations between kurtosis and changes in hearing thresholds at various frequencies, and explore kurtosis's role in estimating NIHL and its integration into occupational hearing loss prevention programs.

Background: Occupational heat stress recommendations aim to achieve thermal equilibrium and keep core temperature (T) below 38.0°C. We assessed the recommended alert limit curves when: (1) work-rest ratios are adjusted based on wet-bulb globe temperature (WBGT) at a fixed rate of metabolic heat production (H) and (2) H is adjusted based on WBGT at a fixed work-rest ratio.

Background: Artificial intelligence (AI) can modernize occupational health and safety (OHS) practice and provide solutions to the most complex health and safety challenges. Empirical data on firm-level AI utilization in OHS practice remain limited. The objective of this study was to examine AI use for OHS and firm-level descriptive and OHS characteristics associated with AI use.

Background: Astaxanthin Z-isomers have attracted much attention because recent studies have demonstrated that they exhibit greater bioavailability and biological activity than the naturally predominant all-E-isomer. However, the plasma appearance and tissue distribution of astaxanthin isomers when administered with a diet rich in astaxanthin Z-isomers are largely unknown. To understand the health benefits and safety of astaxanthin Z-isomers, it is important to study the in vivo kinetics of the isomers.

Myocardial infarction (MI), induced by ischemia and hypoxia of the coronary arteries, presents as myocardial necrosis. Patients often experience intense, prolonged retrosternal pain that is unrelieved by rest or nitrate therapy and is frequently associated with high blood myocardial enzyme levels. Physical effort may exacerbate this anxiety, increasing the likelihood of life-threatening consequences such as arrhythmias, shock, or cardiac failure.
