Post-Traumatic Stress Disorder among Emergency Medical Technicians and its Relationship with Occupational Stress and Depression: Post-Corona Screening, Zanjan, 2022.

Objective: Emergency medical technicians (EMTs) are at risk of developing post-traumatic stress disorder (PTSD) as a result of seeing painful events involving suspected COVID-19 patients and being concerned about potentially infecting themselves and their families. Therefore, screening for these disorders is essential in the post-Corona era. This study aimed to investigate the prevalence of PTSD among EMTs and its relationship with occupational stress and depression when dealing with patients with suspected COVID-19. Methods: This cross-sectional study was conducted on EMTs at Zanjan University of Medical Sciences using a convenience sampling method. Data were collected using a demographic information questionnaire, PTSD checklist, occupational stress questionnaire, and the Goldberg depression scale. The data were analyzed using SPSS software. Statistical tests such as Pearson correlation and logistic regression analysis were used to evaluate the data. Result: 205 EMTs participated in this cross-sectional study. The mean and standard deviation of PTSD was 37.13±12.93 (17-85), and according to the cut-off (45), the prevalence of PTSD was 30.7%. There was a direct and significant association between the total PTSD and depression scores (r=0.435, p=0.001). Some occupational stress domains, such as demand (r=0.306, p=0.001), colleague support (r=0.149, p=0.033), and communication (r=0.293, p=0.001) had a significant association with PTSD. The domains of sadness in depression (OR=1.074, p=0.027) and demands in occupational stress (OR=1.872, p=0.029) were the most important predictors of PTSD. Among demographic variables, employment status was the most important protective factor for PTSD (OR=0.378, p=0.038). Conclusion: PTSD affected one-third of EMTs, and it had a significant relationship with various dimensions of depression and occupational stress. Due to the chronic nature of these diseases, policymakers are advised to prioritize psychological screening of EMTs as part of the post-Corona policy.

Avicenna's doctrine about arterial hypertension.

Arterial hypertension is a major risk factor for the development of cardiovascular diseases. Data from observational studies indicate that it may affect 90% of the general population during their lifetime. Despite much research that has been done, the exact cause of this disorder is still unknown. Avicenna (Ibn Sina) in his masterpiece The Canon of Medicine described most of the clinical features, causes, and complications which are consistent with hypertension symptoms based on modern medicine. He described in detail the symptoms of hypertension such as headache, heaviness in the head, sluggish movements, general redness and warm to touch feel of the body, prominent, distended and tense veins, fullness of the pulse, distension of the skin, coloured and dense urine, loss of appetite, weak eye sight, impairment of thinking, yawning, and drowsiness. Moreover, Avicenna described haemorrhage and sudden death as the complications of hypertension. Due to the importance of this issue, we wanted to call the reader's attention to Avicenna's views about what corresponds to hypertension in modern medicine.
