Bafgh Central Iron Ore Workers\' Health Problems Based on Work Schedules

Introduction: Work-shifting is one of the inevitable achievements of technology and has become a part of the 24-hour community around the world. However, it has been considered as a health hazard, which can have adverse effects on various aspects of human life. Working in mines is a job that many people work in shifts in it and according to the specific conditions of the mine, they cannot adapt to it. So, the present study was conducted to investigate the health problems associated with work shifts in Bafq Central Iron Ore. Methods: This cross-sectional descriptive analytical study was carried out in central iron ore using stratified random sampling. The sample size consisted of 310 workers using the Morgan table. Data were collected using a researcher-made questionnaire and analyzed by SPSS 21 software Results: The results showed a significant relationship between work shift and health problems of the employed workers. There was also a significant relationship between shifting and psychosocial problems. There was no significant relationship between work-shift and cardiovascular, skeletal, and gastrointestinal problems. Conclusion: The results of this study showed that shift-working is related with health problems and mental and psychological problems. Therefore, by developing appropriate shift schedules and holding counseling sessions and appropriate training for employees in different fields, the above problems can be reduced

Evaluation of hematological parameters alterations in different waves of COVID-19 pandemic: A cross-sectional study.

BackgroundThe occurrence of variations in routine hematological parameters is closely associated with disease progression, the development of severe illness, and the mortality rate among COVID-19 patients. This study aimed to investigate hematological parameters in COVID-19 hospitalized patients from the 1st to the 5th waves of the current pandemic.MethodsThis cross-sectional study included a total of 1501 hospitalized patients with laboratory-confirmed COVID-19 based on WHO criteria, who were admitted to Shahid Sadoughi Hospital (SSH) in Yazd, Iran, from February 2020 to September 2021. Throughout, we encountered five COVID-19 surge waves. In each wave, we randomly selected approximately 300 patients and categorized them based on infection severity during their hospitalization, including partial recovery, full recovery, and death. Finally, hematological parameters were compared based on age, gender, pandemic waves, and outcomes using the Mann-Whitney U and Kruskal-Wallis tests.ResultsThe mean age of patients (n = 1501) was 61.1±21.88, with 816 (54.3%) of them being men. The highest mortality in this study was related to the third wave of COVID-19 with 21.3%. There was a significant difference in all of the hematological parameters, except PDW, PLT, and RDW-CV, among pandemic waves of COVID-19 in our population. The highest rise in the levels of MCV and RDW-CV occurred in the 1st wave, in the 2nd wave for lymphocyte count, MCHC, PLT count, and RDW-SD, in the 3rd wave for WBC, RBC, neutrophil count, MCH, and PDW, and in the 4th wave for Hb, Hct, and ESR (p ConclusionThe findings of our study unveiled notable variations in hematological parameters across different pandemic waves, gender, and clinical outcomes. These findings indicate that the behavior of different strains of the COVID-19 may differ across various stages of the pandemic
