Article Synopsis
  • The Star Excursion Balance Test (SEBT) is an effective way to assess dynamic balance in individuals with knee osteoarthritis, particularly those preparing for total knee arthroplasty (TKA).
  • This study found SEBT to be highly reliable, with an intraclass correlation coefficient ranging from 0.993 to 0.998, indicating consistent results over multiple trials.
  • While SEBT showed significant improvements after TKA and correlated with performance-based outcome measures (PBOMs), it does not reflect changes in functional outcome improvements, as measured by the Oxford Knee Score (OKS).

Article Synopsis
  • Three-dimensional gait analysis is crucial for understanding joint loading in hip osteoarthritis, with the external hip adduction moment (EHAM) serving as a key measure.
  • This study assessed how different static foot positions (20° toe-in, straight, and 20° toe-out) affected walking dynamics in twelve participants.
  • Results indicated significant changes in EHAM and various hip and ankle movement metrics, underscoring the need for consistent foot positioning in static trials to improve research reliability.

Bacterial coinfection among patients with confirmed coronavirus disease 2019 (COVID-19) is a critical medical concern that increases the disease severity and mortality rate. The current study is aimed at evaluating the effects of bacterial coinfections among COVID-19 patients, especially in relation to degree of severity and mortality. A retrospective study was conducted for patients with positive COVID-19 test, admitted to a regional COVID-19 hospital in Jeddah, Saudi Arabia, between May and August 2020.

Background: Prior research has revealed notable declines in health-related quality of life (HRQoL) and substantial psychological impacts among individuals infected with COVID-19. However, there is a noticeable gap in studies addressing the enduring long-term effects of COVID-19 on HRQoL and psychological well-being.

Objective: The current study investigated and compared short and long-term effects of COVID-19 on HRQoL and psychological outcomes among the Saudi population.

Coronavirus Disease 2019 (COVID-19) vaccination is the most effective protective measure to control the spread of infections and provide protection against hospitalization and mortality during the pandemic. There was a necessity to measure public knowledge and acceptance for COVID-19 vaccines in different countries. Thus, the current study is aimed at evaluating the knowledge, attitude, and practice of the population in all regions of Saudi towards COVID-19 vaccination.

A range of natural products have been extensively studied for their chemopreventive potential for cancer, including those that inhibit growth and induce apoptosis. Sidr honey derived from the or tree (, , or ) is used in a wide range of traditional medicine practices. In the current study, the Saudi Sidr honey was analyzed by means of a GC-MS chromatogram and investigated for its antiproliferative effects on colorectal cancer cells (HCT-116), breast cancer cells (MCF-7), and lung cancer cells (A-549), as well as its apoptosis induction and cell cycle arrest potentials against human colorectal cancer cells (HCT-116).

Objective: This study aimed to determine the prevalence of knee osteoarthritis (OA) in Saudi Arabia and the association between knee OA and modifiable and non-modifiable risk factors.

Methods: A self-reported, population-based, cross-sectional survey between January 2021 and October 2021 was conducted. A large, population-representative sample (n = 2254) of adult subjects aged 18 years and over from all regions of Saudi Arabia was collected electronically using convenience sampling.

Background: Gait analysis has been used extensively for computing knee kinematics and kinetics, in particular, in healthy and impaired individuals. One variable assessed is the external knee adduction moment (EKAM). Variations in EKAM values between investigations may be caused by changes in static standing position, especially foot placement angles which may increase or reduce any differences seen.

Trends in routine laboratory tests, such as high white blood cell and low platelet counts, correlate with COVID-19-related intensive care unit (ICU) admissions. Other related biomarkers include elevated troponin, alanine aminotransferase, and aspartate transaminase levels (liver function tests). To this end, the aim of this study was to investigate the effect of changes in laboratory test parameters on ward-based and ICU COVID-19 patients.

Background: For individuals with knee osteoarthritis (OA), stair negotiation is a challenging task and the first task during which they report pain due to the high knee loading required. The use of lateral wedge insole (LWI) has been found to reduce loading in patients with OA but not to reduce pain, whereas the use of knee sleeve has been shown to result in good pain reduction. Understanding the effect of combining LWI and knee sleeve use on healthy individuals before testing on individuals with knee OA is an important step.

Objective: Healthcare workers (HCWs) are the backbone of the healthcare system and a skilled and healthy workforce is vital during a health crisis, such as the present coronavirus disease 2019 (COVID-19) pandemic. Healthcare workers are at higher risk of exposure to and transmission of the severe acute respiratory coronavirus-2 (SARS-CoV-2). Hence, HCWs should possess good knowledge and attitudes toward COVID-19 to protect not only themselves but also their colleagues, families and the larger community.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is an emergent infectious pathogen causing an acute respiratory disease called corona virus disease 2019 (COVID-19). Virus transmission may occur by contact, droplet, airborne or via contaminated surfaces. In efforts to effectively control the COVID-19 outbreak, the world health organization (WHO) and the Saudi Ministry of Health (MOH) have advised the public to practice protective measures to reduce transmission of the virus and reduce incidence of infection.
