Background: Cardiovascular diseases, including hypertension, are a leading cause of death in developing and developed countries. Mercury can induce hypertension and atherosclerosis in experimental animals and humans. The assessment of the effect of mercury on the occurrence of cardiovascular system disturbances in the population is an essential task. The aim of this study was to assess the association between mercury concentration in urine and the risk of fatal cardiovascular disease during ten coming years.
Material And Methods: The study included chemical factory workers who used mercury in the chlorine production.
Results: The mean urine concentration of mercury in 154 workers was 4.9 +/- 11.2 microg/g creatinine. The most common disease was hypertension.
Conclusions: The cardiovascular risk was higher in workers exposed to small or moderate mercury levels than in workers exposed to mercury vapor in high concentrations. Furthermore, the negative association was observed between mercury exposure and smoking in workers with low urinary excretion of mercury.

Space missions have revealed certain disincentive factors of this unique environment, such as microgravity, cosmic radiation, etc., as the aerospace industry has made substantial progress in exploring deep space and its impacts on human body. Galactic cosmic radiation (GCR), a form of ionizing radiation, is one of those environmental factors that has potential health implications and, as a result, may limit the duration - and possibly the occurrence - of deep-space missions.

With technological development, ionizing radiation has found applications in numerous occupations. However, the determination and quantification of the damage resulting from exposure to it remains rather unclear, along with the damage to particular organs. The aim of this systematic review was to investigate the relationship between low-dose ionizing radiation (LDIR) in exposed workers and possible functional changes and cancer development in the thyroid gland.

Background/objectives: To effectively support children's learning and well-being, primary educators must thoroughly understand child trauma. Being 'trauma informed' means recognizing the impact of trauma and responding supportively, which can help mitigate its adverse effects on learners. This study explored the understanding of childhood trauma among primary school teachers in Limpopo province, focusing on the circuits of Mvudi and Dzindi due to their high prevalence of childhood traumatic experiences.

Unlabelled: Workers may be exposed to conditions that put their physical and mental integrity at risk, from workplace settings to climate characteristics. Heat stress is a harmful health condition caused by exceeding the human body's tolerance limits, leading to illness and increasing the chance of work accidents. Heat stress indexes, such as the Humidex and the Heat Index (HI), are used to measure these impacts.
