Background: Lead (Pb) brings about a variety of cognitive, mental, renal, and blood system disorders by inducing oxidative stress. The aim of this study is to compare blood and urine parameters in the workers exposed to Pb and zinc (Zn) with those in the control group. Materials and Methods: An analytical cross-sectional study was conducted with a total number of 134 subjects. The case group included 67 male workers with the age range of 22-65 who had at least worked a minimum of one work shift for two years in the Zn-Pb mine located in the southwest of Arak, Iran. Control subjects consisted of 67 farmers of a village near the mine who had no history of occupational exposure to Pb, Zn, and other metals. Mental disorders were evaluated through the standard Scl-90-R while cognitive disorders were evaluated via the Mini Mental Status Examination (MMSE). Results: The mean level of blood and urine parameters did not reveal significant differences between the two groups. The mean scores of physical complaints, anxiety, and aggression scales were significantly higher in the case group than the control (p<0.05), whereas the mean scores on MMSE did not reveal a significant difference between the two groups. Conclusion: The oxidative stress of Pb led to mental disorders as a result, the mine workers suffered from more psycho- pathology and are in need of greater care. Due to the impacts of Pb and Zn, the proper use of safety equipments and taking daily showers can reduce the risk of absorption of toxic agents and their subsequent hazards for workers.

Introduction: Paints are composed of extensive variety of hazardous substances, such as organic solvents and heavy metals. Occupational exposure to paint increases oxidative stress, hematological disorders, and DNA injury. This study was performed to explore the beneficial effects of Selvit on the paint workers by measuring total antioxidant capacity, lipid peroxidation, and blood parameters as main oxidative stress biomarkers.

Materials and Methods: This clinical trial study was conducted on 25 male workers who worked in the paint factory. Serum markers such as total antioxidant capacity (TAC), lipid peroxidation (LPO) and also hematological parameters were measured before and after using Selvit (14 days). SPSS software was used for data analyses and paired t-test and Pearson correlation analysis were applied.

Results: Results showed that after using the Selvit, an increase in TAC and a decrease in LPO were observed but they were not significant. Also, aspartate transaninase significantly decreased after using Selvit and high density lipoprotein significantly increased.

Conclusion: Selvit have beneficial effect on hematological parameters due to its antioxidant capacity.

Introduction: The fundamental role of marital satisfaction is vital in family formation and marriage survival. Marital dissatisfaction can make couples fail to solve their conflicts. Marital discontent, combined with job-related stress such as pre-hospital emergencies, can lead to heightened conflict in job responsibilities. It leads to the effect on personnel, patients, and their families. Therefore, this study aimed to investigate the marital satisfaction of pre-hospital emergency personnel at Qom University of Medical Sciences in 2023.
Methods: This cross-sectional study was conducted on 200 pre-hospital personnel of Qom University of Medical Sciences in May 2023. The sampling method was a stratified cluster. The data collection tool included the "Demographic Information" checklist and Enrich's "Marital Satisfaction" questionnaire. Data analysis was done using descriptive tests, Independent T-test, and Regression.
Results: The average age of the participants was 37.3 ± 7.06. More than half of the participants had a bachelor's degree. Most people had rotating shifts. The average score of marital satisfaction was 145.94 ± 22.21. Based on the results of the multivariate regression test, the variables of education, employment status, work experience, type of shift, having a second job, and having a job other than medical staff explain 63% of the variance of marital satisfaction of pre-hospital personnel.
Conclusions: According to the findings of the present study, in general, the marital satisfaction of pre-hospital emergency personnel of Qom University of Medical Sciences is at an average to high level. People with a fixed shift, with a second job, high work experience, without a fixed job status, and bachelor's and associate's degrees had less marital satisfaction than others. Therefore, managers and policymakers in the health field must pay more attention to the quality of family life, especially the married life of pre-hospital emergency workers with the mentioned conditions.
