The second most frequent shoulder condition is subacromial impingement syndrome. Impingement can be classified as either anterosuperior or posterosuperior. Faulty posture, altered scapular or glenohumeral kinematics, posterior capsular tightness, and acromial or coracoacromial arch pathology are all potential extrinsic mechanics that can lead to Subacromial impingement syndrome. The purpose of this review is to find the different variation in translation that takes place in the glenohumeral joint in Subacromial impingement syndrome in overhead workers. Methods: We performed a review of the various translations observed in the glenohumeral joint in subacromial impingement syndrome and discussed the evidence-based studies. For the review, an electronic search for relevant articles using PUBMED, Pedro, Research Gate, and Google Scholar databases up to Dec 2022 was done wherein MeSH search terms and free words were used. Articles underwent the selection process and were selected on the basis of inclusion criteria. Articles were selected based on the author's expertise, self-knowledge and reflective practice. Results: The current study included 11 articles that fulfilled the inclusion criteria suggesting that various humeral translations in overhead workers. The above-reviewed studies provided evidence that based on occupational demands abnormal variations occur. Conclusion: This review has provided an overview of the previous and recent literature on humeral head translation seen in sub-acromial impingement. This study concludes that superior translation is more common as compared to anterior-superior translation and posterior-superior translation.","PeriodicalId":34250,"journal":{"name":"International Journal of Occupational Safety and Health","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136295728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we aimed to identify the association between depression and sleep quality in health workers who faced the COVID-19 pandemic. Methods: A survey was performed on 150 health workers with at least 2 years of working tenure in a public maternal perinatal hospital in Mexico, between September and December 2021. Sociodemographic data, levels of sleep quality, depression, anxiety, and gastrointestinal function were obtained through a self-administered questionnaire. Cardiovascular risk was obtained according to age, lifestyle habits, blood pressure, anthropometry, body composition and biochemical measurements. Results: Those with depression were 10.3 times more likely to have poor sleep quality compared to those without depression, adjusted for gastrointestinal function (95% CI 2.92 – 36.54, p<0.001). Those with depression were 7.23 times more likely to have poor sleep quality compared to those without depression, adjusted for gastrointestinal function, anxiety, and cardiovascular risk (95% CI 1.85-28.14, p<0.001). Conclusion: Health workers’ depression should be considered a predictor of poor sleep quality, especially in those who faced the COVID-19 pandemic.","PeriodicalId":34250,"journal":{"name":"International Journal of Occupational Safety and Health","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136352562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tewari, Sanjeev Kumar","doi":"10.3126/ijosh.v13i4.52917","DOIUrl":"https://doi.org/10.3126/ijosh.v13i4.52917","url":null,"abstract":"Introduction: Agricultural fields like weed management and horticultural operations are the most common and labor-intensive. Most of these tasks are completed with the help of push-pull-type agricultural machinery. The push-pull tasks are mainly done using agricultural machinery (push-pull weeders, manually operated rice transplanters or seeders, long-handled agricultural tools, etc.) by farm workers. Since these are manually operated machinery, long working hours in awkward positions are expected, which causes physical stress and musculoskeletal disorders in the operators. An electromyography study for agricultural workers during push and pull operations was conducted in this study. Methods: To evaluate muscle activity, a laboratory test setup was developed based on the ergonomic criteria of the uniform force application. Four loads (50, 100, 150, and 200 N) and the four most used upper body muscles (middle deltoid MD, triceps brachii TR, brachioradialis BR, and biceps brachii BI) during push-pull operations were selected for an electromyographic study on twelve medically fit agricultural workers as subjects. This study attempted to minimize muscle activity, thereby reducing overexertion injuries. Results: The most activated muscles during the pushing and pulling operations were TR and BR, respectively. The muscle activity of the TR during the pushing task was found to be 109 µV, 135 µV, 178 µV and 195 µV at loads of 50 N, 100 N, 150 N, and 200 N, respectively. During the pulling task, the muscle activity of the BR was 51 µV, 66 µV, 80 µV, and 126 µV at loads of 50 N, 100 N, 150 N, and 200 N, respectively. Conclusion: For all subjects, a load of 200 N was found difficult to operate compared to other selected loads during push and pull operations. Muscle activation was found to increase with increasing load for each of the selected muscles.","PeriodicalId":34250,"journal":{"name":"International Journal of Occupational Safety and Health","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136352883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their impact ranges from injuries to death. In Indonesia, traffic accidents are dominated by students who use motorcycles. With this in mind, this study is focused on identifying the driving attitudes that are responsible for traffic accidents among university students. Methods: The cross-sectional survey study was conducted from January 2023 to February 2023, located in the Special Region of Yogyakarta, Indonesia. Data was gathered using simple random sampling on 97 students based on experiences while driving such as safety attitude, frequencies on motorcycle inspections, and driving attitude. The next step is a comparison between results based on student experiences and risk assessment by experts. The expert assessment used two personnel of Police Resort from Yogyakarta and Purworejo, Indonesia. Results: Participants were divided into 81.4% men (N=79) and 18.6% women (N=18), with a mean age ± standard deviation of 21 ± 1.8 years. Awareness of safety attributes is demonstrated by the use of helmets by 92.78% of participants, and motorcycle inspections on rearview mirrors (85.57%), rims &amp; tires (79.38%), and brakes (71.13%). In terms of road driving attitudes, students drive with fatigue (82.47%) and sick (61.86%), drive in bad weather (78.35%), and exceed the standard of speed (53.61%). The results of the risk assessment show that 7 variables have a high risk, namely helmet, inspection on the brake, driving in fatigued physical condition, driving in sick physical condition, using gadgets when driving, traffic sign violation, and overspeeding. Conclusion: Based on these results, it show that students' driving readiness is quite good with the attributes of vehicle safety and feasibility. This is shown by the use of helmets and break checks by students with the highest risk on the road. However, the need to be concerned is that the bad riding attitude includes physical health conditions, driving according to traffic safety standards, and paying attention to weather conditions. Improvements are needed especially by drivers to create safe and secure driving conditions.","PeriodicalId":34250,"journal":{"name":"International Journal of Occupational Safety and Health","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136352910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
