Introduction: Musculoskeletal disorders are the most common debilitating causes in workers and the main reason for medical leaves. Medial leave brings health, social, and economic consequences for individuals and society. The relationship between medical leaves due to pain and discomfort in different parts of the body and physical activity level at work, practice of sport, and leisure time in workers in cement industry in 2019 was examined. Methods: A descriptive-analytical study was conducted on 150 workers of a cement factory. The participants were selected randomly. Data gathering tools were demographics form, Nordic Musculoskeletal Questionnaire, and Baecke Physical Activity Questionnaire and the collected data was analyzed using SPSS (v.22). Results: The participants noted that the main painful areas over the past year were the waist, knee, ankle, and neck. There was a significant relationship between medical leave due to pain in the neck and overtime work. There was a significant relationship between the type of work activity and medical leave due to a pain in knee and ankle. Conclusion: The workers who used such medical leaves had a higher PAL at work. PAL at work increased the requests of medical leaves due to the pain in knee and waist. The PAL at sport practice decreased the rate of request for medical leave due to a pain in the Waist and Knee.

Introduction: Job burnout is a common phenomenon in health care employees who need to deal with and witness people’s problems and expectations. By definition, occupational cognitive failures appear as problems in performing daily tasks like forgetting them or having difficulty in focusing on them. The present study is an attempt to investigate the relationship between job burnout and occupation cognitive failures in nurses of educational hospitals. Methods: This descriptive-analytic study was done in 2018 and consisted of nurses from the Ardebil Hospital (n= 2,250). Using the Cochran formula, 328 hospital nurses were selected from different units by simple random sampling method. The data were collected by two professional health experts through interviewing and completing demographic questionnaires, job burnout questionnaire, and occupational cognitive failure questionnaire. Statistical analyses was performed in SPSS19. Results: A total of 328 nurses participated in the study. The mean age of the subjects was 34±8 years, varying from 22 years to 58 years. Occupational cognitive failures increased with the increase in emotional exhaustion and depersonalization; while it decreased with an increase in individual accomplishment. Conclusion: There was a significant relationship between occupational cognitive failure and different dimensions of job burnout. In addition, different dimensions of job burnout (Emotional Exhaustion, Depersonalization, and Personal accomplishment) could be associated with possible errors in information processing (memory, attention, and functioning).

The kidneys have a close functional relationship with other organs especially the lungs. This connection makes the kidney and the lungs as the most organs involved in the multi-organ failure syndrome. The combination of acute lung injury (ALI) and renal failure results a great clinical significance of 80% mortality rate. Acute kidney injury (AKI) leads to an increase in circulating cytokines, chemokines, activated innate immune cells and diffuse of these agents to other organs such as the lungs. These factors initiate pathological cascade that ultimately leads to ALI and acute respiratory distress syndrome (ARDS). We comprehensively searched the English medical literature focusing on AKI, ALI, organs cross talk, renal failure, multi organ failure and ARDS using the databases of PubMed, Embase, Scopus and directory of open access journals. In this narrative review, we summarized the pathophysiology and treatment of respiratory distress syndrome following AKI. This review promotes knowledge of the link between kidney and lung with mechanisms, diagnostic biomarkers, and treatment involved ARDS induced by AKI.

The high mortality rates associated with acute kidney injury are mainly due to extra-renal complications that occur following distant-organ involvement. Damage to these organs, which is commonly referred to as multiple organ dysfunction syndrome, has more severe and persistent effects. The brain and its sub-structures, such as the hippocampus, are vulnerable organs that can be adversely affected. Acute kidney injury may be associated with numerous brain and hippocampal complications, as it may alter the permeability of the blood-brain barrier. Although the pathogenesis of acute uremic encephalopathy is poorly understood, some of the underlying mechanisms that may contribute to hippocampal involvement include the release of multiple inflammatory mediators that coincide with hippocampus inflammation and cytotoxicity, neurotransmitter derangement, transcriptional dysregulation, and changes in the expression of apoptotic genes. Impairment of brain function, especially of a structure that has vital activity in learning and memory and is very sensitive to renal ischemic injury, can ultimately lead to cognitive and functional complications in patients with acute kidney injury. The objective of this review was to assess these complications in the brain following acute kidney injury, with a focus on the hippocampus as a critical region for learning and memory.
