Randomized Controlled Trial
Effects of Aerobic Exercises on Serum Levels of Myonectin and Insulin Resistance in Obese and Overweight Women.
Background and Aim: Obesity is associated with cardiovascular diseases, metabolic syndrome, and diabetes and insulin resistance. Myonectin is a myokine mostly secreted from skeletal muscles and inversely associated with obesity. The aim of the present study was to evaluate the effects of 8 weeks of aerobic exercises on serum levels of myonectin and insulin resistance in obese and overweight women. ⋯ Results: Serum levels of myonectin in the experimental group increased significantly (P=0.000); however, insulin resistance significantly decreased in the experimental group (P=0.000). Conclusion: Therefore, considering the role of myonectin in increasing fatty acid uptake, exercise training can play an essential role in decreasing obesity-related diseases and metabolic syndrome; this effect is partly related to the roles of myonectin. Therefore, the use of this type of exercise is recommended to reduce the risk of diseases associated with obesity and metabolic syndrome.

Introduction and Objective: Medical errors and adverse events are among the major causes of avoidable deaths and costs incurred on health systems all over the world. Medical errors are among the main challenges threatening the safety of patients in all countries and one of the most common types of medical errors is medication errors. This study aimed to determine the frequency, type, and causes of medication errors in the emergency and pediatric wards of hospitals affiliated to Tehran University of Medical Sciences in 2017. ⋯ On the other hand, the most common causes of medication errors in clinical wards were the following: illegible physician orders, shortage of manpower and high workload, incomplete physician orders, the use of lookalike and sound-alike drugs, absence of pharmacist/pharmaceutical expert in the ward, lack of dosage forms appropriate for children, and lack of adequate training regarding drug therapy. Discussion and Conclusion: Considering the results of this study, it is necessary to reduce the workload and working hours of nurses, increase medical staff's awareness of the significance of medication errors, revise the existing techniques of drug prescription, and update the indices of human resource in hospitals. It is also necessary to correct the process of naming and selecting the dosage forms of drugs by the industry.

Introduction: Patients under mechanical ventilation are usually in the supine position due to various arterial/venous tubes attached to them. Although many studies emphasize the advantages of prone position for oxygenation, some studies enumerate its disadvantages. Objective: The aim of the present research was to determine the effect of prone position on oxygenation of patients with Acute Respiratory Failure (ARF) under mechanical ventilation in the Intensive Care Unit (ICU). ⋯ Findings: The prone position had a significant relation to Oxygen Arterial Blood (Sao2) and Pressure of Arterial Oxygen (pao2), (p-value<0.05). Also, on days one and two, there was no significant relationship between the prone position and physiological signs; however, this relation was significant on day three (p-value<0.05). Conclusions: Results showed that the prone position improves sao2 and pao2 without adverse effect on physiological signs.
