The prevalence of work-related musculoskeletal disorders among sonographers.

Background: Work-related musculoskeletal disorders (WRMSDs) have a significant effect on the psychological and physical function of the sonographer.

Objective: This study is concerned about finding the prevalence of WRMSDs among sonographers in the Kingdom of Saudi Arabia and assessing how to improve future practices and develop guidelines for safe, pain-free ultrasound departments.

Methods: A survey was distributed to sonographers working in major hospitals in Riyadh, Saudi Arabia (n = 100, 83% response rate).

Reducing computed tomography radiation dose in diagnosing pulmonary embolism.

Background And Objective: Computed tomography angiography plays a major role in the diagnosis of pulmonary embolism. Radiation dose associated with it is a major concern; therefore it is important to optimize protocols and techniques to ensure minimum radiation dose.

Methods: The study compares two protocols i.

CT radiation dose awareness among paediatricians.

Background: The radiation dose delivered from computed tomography (CT) scanning and the risks associated with ionising radiation are major concerns in paediatric imaging. Compared to adults, children have increased organ sensitivity and a longer expected lifetime in which cancer may develop. Therefore, it is important to investigate the awareness of paediatricians (referring physicians) regarding radiation doses and the associated risks.

Lack of facilities rather than sociocultural factors as the primary barrier to physical activity among female Saudi university students.

Purpose: The Kingdom of Saudi Arabia is experiencing a dramatic increase in physical inactivity, with women having higher levels of inactivity than men among all age groups. It is assumed that factors such as dress codes, restrictions on going outdoors, and conservative norms are the main reasons for women's low physical activity. Our aim was to explore the different parameters related to physical activity, including self-efficacy, as well as the perceived barriers to and benefits of physical activity in young Saudi females.

Alterations in prothrombin time and activated partial thromboplastin time in patients with acute myocardial infarction.

Prothrombin time (PT) and activated partial thromboplastin time (aPTT) respectively measures the extrinsic and intrinsic pathways of coagulation and are used to determine the bleeding or clotting tendency of blood. We compared PT and aPTT levels in acute myocardial infarction (AMI) patients and normal subjects. There were significant increases in PT levels in patients with STEMI (15.
