Metabolic syndrome and its relationship with shift work in petrochemical workers.

Background: The metabolic syndrome is a complex of interdependent risk factors for cardiovascular disease and diabetes. Shift work might have an impact on metabolic variables, and be a risk factor for type 2 diabetes. To date, only few studies have been done on the prevalence of MetS in industrial work environments in Iran, and most of them have been conducted on a small sample size.

Job stress and resilience in Iranian nurses during the COVID-19 pandemic: A case-control study.

Background: The COVID-19 pandemic has created a wide range of sociocultural pressures on nurses. Resilience is defined as one's ability to adapt to an unpredictable situation and it can be a factor in accepting an undesirable psychosocial situation.

Objective: The aim of the present study was to examine resilience in nurses in the face of job stress during the COVID-19 pandemic.

The effects of dyslipidemia on noise-induced hearing loss in petrochemical workers in the Southwest of Iran.

Background: Research has shown that the decrease in the inner diameter of vessels caused by hyperlipidemia lowers the capacity for blood oxygen delivery to the cochlea. This leads to impaired cochlear metabolism and causes hearing problems.

Objective: The effects of dyslipidemia on noise-induced hearing loss in workers were examined.

Evaluation of airborne exposure to volatile organic compounds of benzene, toluene, xylene, and ethylbenzene and its relationship to biological contact index in the workers of a petrochemical plant in the west of Iran.

Nowadays, workers in petrochemical industry might be exposed to organic volatile compounds, including benzene, toluene, ethylbenzene, and xylene (BTEX). The aim of this study was to investigate the concentration of BTEX contaminations and the biological index in employees of petrochemical sites in the west of Iran. The study was conducted as a cross-sectional study on 30 stations and 60 inhalation and biological samples collected in winter and summer.
