Perceived levels of corporate support, colleague support and anxiety in motor courier employees.

OBJECTIVE: The use of motorcycles in commercial transportation is increasing due to its comfortable use in congested traffic conditions and the ease of parking on narrow streets. Motorcycle couriers are among the important members of the delivery industry. The race against time and delivering on time bring along many problems. This study aims to examine the relationships between perceived organizational support, colleague value and stress in motor courier employees. METHOD: Within the scope of the study, 151 motorcycle couriers working in the delivery sector were selected. The study was carried out in the period of June-November 2022. In addition to 15 questions including demographic characteristics with the one-to-one interview method, Spielberger's State and Trait Anxiety Scale, The Perceived Organizational Support Scale and The Coworker Support Scale were applied with the one-to-one interview method. RESULTS: The average age of the 151 couriers included in the study was 29.10 ± 7.01; the working year was 3.26 ± 3.39; the average number of daily trips was 36.47 ± 17.37; the average delivery time was 16.54 ± 10.10 in minutes (median 15); and the average weight of the cargo was 4.94 ± 5.51 (kg) (median: 3.50). The prevalence of occupational accidents in the last year has been 43.3% (n = 61). Examining the causes of the prevalence of accident among the study population, it was found that motorcycle overturning was 20 (32.8%); vehicle hitting the motorcycle was 26 (42.6%); motorcycle hitting the vehicle was 15 (24.6%). When the factors affecting the perceived organizational support were examined, it was found that those with a colleague social support score above 18 were more likely to have an organizational perception score above 80 (95% CI 1.001-4.843) with a rate of [OR] = 2.20 times higher, and those with a status anxiety score above 40 were more likely to have an organizational perception score over 80 with a rate of [OR] = 2.49 times higher (95% CI: 1.156-5.364). In addition, it was seen that the probability of having an organizational perception score above 80 was [OR] = 0.42 times higher (95%CI: 0.200-0.889) in participants who had a work accident. CONCLUSIONS: The intense pace of work and the pressure of fast delivery increase couriers' state and trait concerns. Developing policies to improve the psychosocial working environment for a more decent and healthier working environment that improves the mental health and well-being of couriers is recommended. Commercial food ordering platforms must treat driver safety as important when determining delivery times.

Ergonomic risk assessment of working postures of nurses working in a medical faculty hospital with REBA and RULA methods.

The aim of the study is to reach objective results about the ergonomic risks of nurses' working postures not only by using questionnaires but also by using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methods, which are risk assessment methods used in engineering fields. This study is a cross-sectional study. First of all, 383 nurses were evaluated with a survey. 91.4% of the nurses were women and 6.5% were men. Average age (female: 38.20; male: 31.5), average weight (female: 65.60 kg; male: 81.50 kg), average height (female: 162.7 cm; male: 176.80 cm) and average body mass index (female: 24.80; male: 26) were calculated. In the hospital, which we grouped into in the hospital, which we divided into eight workstations, the REBA and RULA scores of the three nurses working at each workstation were calculated and the average REBA and RULA scores of the workstations were determined. The percentage of those who experienced musculoskeletal pain in the last 1 year at each workstation and the mean REBA-RULA scores were as follows; ward (92%; 6.92-5.69), operating room (98%; 10-7), emergency department (100%; 6.08-5.33), outpatient clinic (75%; 5.5-5.16), intensive care (94%; 6.21-5.57), administrative affairs (94%; 5-5), laboratory (95%; 5.80-5.2) and interventional procedure (92%; 6.4-5.4). In these stations, the highest scores were seen in the operating room. In the questionnaire, 92.46% of the nurses reported having complaints in at least one part of the musculoskeletal system in the last year. The hospital weighted mean score was REBA 6.86 and RULA 5.71. When REBA and RULA measurements were evaluated, it was determined that the risk in the departments where the nurses worked was generally at the medium risk level. REBA and RULA scores indicate that ergonomic changes and adjustments should be made. For this determination, the risks of working postures should be determined with quantitative methods.

Comparative Analysis of Transcriptome Profiles in Patients with Thromboangiitis Obliterans.

BACKGROUND: Thromboangiitis obliterans (TAO) causes vascular insufficiency due to chronic inflammation and abrupt thrombosis of the medium and small arteries of the extremities. In our study, we aimed to determine biomarkers for the diagnosis of TAO by evaluating 15 male TAO patients with Shinoya diagnostic criteria and 5 healthy controls who did not have TAO-related symptoms in their family histories. METHODS: The Clariom D Affymetrix platform was used to conduct microarray analysis on total RNA extracted from whole blood. A total of 477 genes (FC ≤ 5 or >5) common to the fifteen patient and five control samples were selected using comparative microarray analysis; among them, 79 genes were upregulated and 398 genes were downregulated. RESULTS: According to FC ≤ 10 or >10, in the same TAO patient and control group, 13 genes out of 28 were upregulated, whereas 15 genes were downregulated. The 11 key genes identified according to their mean log2FC values were PLP2, RPL27A, CCL4, FMNL1, EGR1, EIF4A1, RPL9, LAMP2, RNF149, EIF4G2, and DGKZ. The genes were ranked according to their relative expression as follows: FMNL1 > RNF149 > RPL27A > EIF4G2 > EIF4A1 > LAMP2 > EGR1 > PLP2 > DGKZ > RPL9 > CCL4. Using protein-protein interaction network analysis, RPL9, RPL27A, and RPL32 were found to be closely related to EIF4G2 and EIF4A1. The Reactome pathway found pathways linked to 28 genes. These pathways included the immune system, cellular responses to stress, cytokine signaling in the immune system, and signaling by ROBO receptors. CONCLUSIONS: By figuring out the protein expression levels of the genes that have been found to explain how TAO disease works at the molecular level, it will be possible to figure out how well these chosen transcripts can diagnose and predict the disease.
