Randomized Controlled Trial
Peer-assisted versus expert-assisted learning in virtual chest x-ray interpretation: A randomized controlled trial.
To compare the effectiveness of peer-assisted learning (PAL) and expert-assisted learning (EAL) in terms of knowledge gain in virtual chest x-ray (CXR) interpretations. The secondary objective was to assess students' satisfaction levels between both groups. ⋯ Peer-assisted learning has equivalent efficacy compared to EAL in a virtual setting. The Students in the PAL group had higher level of satisfaction.

To analyze the impact and distribution of blood groups in different ethnicities and the extent of susceptibility to infection with COVID-19 in Makkah, Saudi Arabia. ⋯ We emphasize that COVID-19 infection is not proportional among ethnically related blood groups. Notably, RhD-negative protect against COVID-19, whereas A and O blood types are more susceptible. Thus, when assessing COVID-19 prognosis and vaccination priority, blood groups A and O are critical.
-
To estimate the prevalence of post- amputation pain among lower-limb amputees and its burden on their lives. ⋯ Post-amputation pain is one of the major consequences of amputation. Pain was poorly managed among these patients. Special considerations should be obtained to manage these patients' pain and reduce their suffering.
-
To reveal the demographic features, prognostic factors, and tumor characteristics of patients with non-epithelial ovarian tumors (NEOTs). ⋯ The findings for protective and risk factors were inconclusive. Patients with GC tumors had better survival outcomes than those with the other subtypes.

To evaluated obesity-related morbidity prevalence among overweight/obese children and adolescents in Saudi Arabia, adiposity indicators and insulin resistance as obesity-related morbidity predictors. ⋯ Obesity-related morbidity is widely prevalent among obese children and insulin resistance is a key factor in its prediction. Clinical adiposity indices, given their accuracy and practicability, are important predictors of obesity-related morbidity.
