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 study the genotype and allele frequency of the fat mass and obesity-associated (FTO) rs8050136 A>C genetic variant and investigate its association with type 2 diabetes mekkitus (T2DM) parameters. ⋯ Our findings show that the FTO rs8050136 A>C variant is not associated with T2DM in the Saudi population.

To find the association between environmental and occupational exposures and chronic rhinosinusitis (CRS) development. ⋯ We found that smoking was the most aggravating environmental factor. Chronic rhinosinusitis symptoms' severity increased with direct contact with allergens. Thus, the greatest proportion of patients with CRS was those with blue-collar occupations, such as firefighters, farmers, and fishermen.

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.
