Development and validation of the questionnaire of OSCE's educational effects.

Introduction: One of the most common assessment tools for examining the competencies of health professionals is the Objective Structured Clinical Examination (OSCE).

Methods: In this study, an Educational Effects of OSCE Questionnaire (EEOQ) was developed and validated in seven steps: (1) Reviewing the literature, (2) Holding focus groups, (3) Synthesizing the results of literature review and focus groups, (4) Developing items, (5) Evaluating content validity, (6) Conducting cognitive interviews, and (7) Implementing a pilot test.

Results: The analysis of the literature review and focus groups revealed that the educational effects of OSCE are influenced by factors related to the test, the examiner, the peers, and the student.

The effect of Nifedipine on embryo transfer outcomes: A randomized clinical trial.

Background: Endometrial receptivity is crucial for embryo implantation, and excessive uterine contraction reduces success. Nifedipine which is a calcium channel blocker, could decrease uterine contraction and improve pregnancy outcomes.

Objective: This study aimed to assess the effect of Nifedipine before embryo transfer on the pregnancy outcome in women undergoing in vitro fertilization (IVF) in a tertiary center in Iran.

The relationship between thyroid function tests and sleep quality: cross-sectional study.

Introduction: The relationship between sleep and hormones have long been recognized. Studies indicated that sleep quality is one of the major modulatory effects on the endocrine system. In this study, we aimed to assess the serum concentration of thyroid hormones in individuals who suffered from low quality sleep.

The effect of subjective sleep latency on BMI of medical interns during and before COVID-19 pandemic.

Objectives: Longer subjective sleep latency and eveningness chronotype are associated with higher BMI. Moreover, COVID-19 lockdown changes have been associated with increased BMI. The aim of this study was to investigate the effect of subjective sleep parameters on BMI of medical interns during and before COVID-19 pandemic.

Novel Regional Nerve Blocks in Clinical Practice: Evolving Techniques for Pain Management.

This review examines the use of novel US-guided nerve blocks in clinical practice. Erector spinae block is a regional anesthesia technique doing by injecting a local anesthetic among the erector spinae muscle group and transverse processes. The phrenic nerve is a branch of the cervical plexus, arising from the anterior rami of cervical nerves C3, C4, and C5.

Symptom Prediction and Mortality Risk Calculation for COVID-19 Using Machine Learning.

Early prediction of symptoms and mortality risks for COVID-19 patients would improve healthcare outcomes, allow for the appropriate distribution of healthcare resources, reduce healthcare costs, aid in vaccine prioritization and self-isolation strategies, and thus reduce the prevalence of the disease. Such publicly accessible prediction models are lacking, however. Based on a comprehensive evaluation of existing machine learning (ML) methods, we created two models based solely on the age, gender, and medical histories of 23,749 hospital-confirmed COVID-19 patients from February to September 2020: a symptom prediction model (SPM) and a mortality prediction model (MPM).

The Impact of Optimal Dose of Ketamine on Shivering Following Elective Abdominal Hysterectomy: A Randomised Comparative Study.

Background: Following surgery, patients frequently suffer from shivering, and this can lead to postoperative complications and discomfort.

Objectives: This study aimed to compare the effect of ketamine on patients' shivering following an elective abdominal hysterectomy. Patients were given either Ketamine (0.

Effect of Preoperative Duloxetine on Opioid Consumption in Women Undergoing Abdominal Hysterectomy: A Randomized, Double-Blinded, Placebo-Controlled Trial.

Background: Pain is one of the most challenging issues following surgery, and it is crucial to provide adequate and appropriate pain control measures.

Objectives: This study assessed the efficacy of preoperative duloxetine in controlling postoperative pain in women following an abdominal hysterectomy in Yas Hospital affiliated to Tehran University of Medical Sciences between December 2019 and April 2020.

Methods: The study involved 80 women who were candidates for elective abdominal hysterectomy.

Extracorporeal Hemoperfusion as a Potential Therapeutic Option for Severe COVID-19 patients; a Narrative Review.

The 2019 novel coronavirus (officially known as severe acute respiratory syndrome coronavirus 2, SARS-CoV2) was first found in Wuhan, China. On February 11, 2020, the World Health Organization (WHO) has declared the outbreak of the disease caused by SARS-CoV2, named coronavirus disease 2019 (COVID-19), as an emergency of international concern. Based on the current epidemiological surveys, some COVID-19 patients with severe infection gradually develop impairment of the respiratory system, acute kidney injury (AKI), multiple organ failure, and ultimately, death.
