Mental Illnesses and Quality of Sleep Among Nurses Working at a Tertiary Hospital in Riyadh During the COVID-19 Pandemic.

Objectives This study primarily aimed to estimate the prevalence of mental illnesses (depression, anxiety, and stress) along with the poor quality of sleep, with a secondary focus on determining whether there was an association between mental health and quality of sleep among nurses working at King Khalid University Hospital, Riyadh, Saudi Arabia, during the COVID-19 pandemic. Methods A cross-sectional study was conducted from June to December 2021 during the COVID-19 pandemic on 309 nurses from different departments at King Khalid University Hospital. Depression, anxiety, and stress were measured by the Depression, Anxiety, and Stress Scale - 21 Items (DASS-21), and sleep quality was measured by the Pittsburg Sleep Quality Index (PSQI) via an online survey.

Lisinopril has a cardio-protective effect on experimental acute autoimmune myocarditis in rats.

Methods: This study was performed at the Anatomy Department, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia from May to December 2012. Eighty rats were divided into 4 groups.

Radiate ligament shortening and idiopathic scoliosis.

Objective: To investigate the possible role of radiate ligament in idiopathic scoliosis.

Methods: This study was designed as a case-control study adapted to cadavers. Eighteen human cadavers, 12 males and 6 females of Caucasian race, with a mean age of 55 years were studied at the Department of Anatomy, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia from November 2010 to February 2012.

Normal knee angles in the adult Saudi population.

Objective: To study knee angles in the adult Saudi population and compare their values to the published data from other populations.

Methods: Antero-posterior bilateral radiographs of 333 normal knees of 120 males and 213 females, with age range of 18-65 years, were studied retrospectively at King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia, from January 2009 to December 2009. Tibiofemoral (TFA), lateral distal femoral (LDFA), and lateral proximal tibial (LPTA) angles were measured and the mean of each angle was calculated.
