The aims of this study were to compare the incidence of occupational accidents during one-year periods of the COVID-19 Pandemic and before the COVID-19 Pandemic, and to determine in which sectors occupational accidents occurred and what types of injuries were sustained in the population of Tokat, Turkey. A retrospective review was made of the records of Tokat State Hospital of patients injured in occupational accidents between 12.03.2019 and 11.03.2021. The patients injured in occupational accidents were classified according to age, gender, sector, accident type, trauma localization and type, time of the accident, and outcome of the injuries. Of 608 patients injured in occupational accidents, 384 (63.2%) were injured in the period before the pandemic and 224 (36.8%) were injured in the period during the pandemic (p < 0.001). Most work-related injuries occurred in the industry sector (n = 287; 47.2%; p < 0.001). Occupational accidents increased in the service sector (p < 0.001), but decreased in other sectors. The increase in occupational accidents in the health sector (p < 0.001) and transportation sector (p < 0.05) within the service sector caused a general increase despite the decrease in other service sectors (p > 0.05). In current study, the increase in the number of injuries in the transportation sector due to the increase of motor courier accidents, in health sector, and in pandemic quarantines were remarkable. It was evaluated that this narrow-scoped study pioneered comprehensive studies on the measures that can be taken to prevent occupational accidents in such pandemics in the future.

The pelvic inlet is one of the critical constraints within the relatively narrow birth canal for the passage of the fetal head. This study tested the hypothesis that the shape of the pelvic inlet differs between females and males, with the expectation that the female pelvic inlet is more elliptical than its male counterpart. Abdomino-pelvic computed tomography images from 600 cases, equally distributed by sex and age groups, were analyzed. Using 3D reconstruction, image processing, ellipse fitting, and a genetic algorithm, we evaluated whether the proposed measures of elliptical similarity in pelvic inlet shape varied by sex. Additionally, discriminant analysis was employed to assess the accuracy of sex determination based on these measures. The results demonstrated significant differences between the two sex groups for all proposed measures. Discriminant analysis achieved a maximum sex determination accuracy of 79.7%. These findings support the hypothesis that the female pelvic inlet has evolved to be more elliptical compared to the male pelvic inlet. If validated by future studies on diverse populations, this hypothesis may gain broader scientific acceptance.
