Randomized Controlled Trial
"Smart Optometry" phone-based application as a visual acuity testing tool among pediatric population.
To evaluate the validity of a smartphone-based application for visual acuity (VA) testing in children and to compare parent and clinician-performed VA to standard VA assessment. ⋯ "Smart Optometry" phone application was found to be an acceptable home-based VA testing tool with good inter-rater reliability for young children showing good sensitivity in detecting subnormal VA, but lower sensitivity in detecting amblyopia.

To assess the survival of COVID-19 patients in Saudi Arabia and to investigate possible mortality predictors. ⋯ Age, asthma, some in-hospital complications are important survival indicators in hospitalized COVID-19 patients. The controllable co-factors should be monitored and managed by healthcare workers to reduce mortality rates in those hospitalized with COVID-19.

To calculate the incidence of new-onset atrial fibrillation (NOAF) in myocardial infarction (MI) patients and examine associated predictors and clinical outcomes of NOAF patients. ⋯ New-onset atrial fibrillation is a relatively common complication of MI, and in our study, it was associated with higher odds of further complications including death. Therefore, identification of MI patients at risk of developing NOAF is crucial. Our study suggests that older age, a previous history of MI, and undergoing CABG are significant predictors of NOAF development.

Randomized Controlled Trial
Effects of different fresh gas flows on carboxyhemoglobin levels: non-invasive carbon monoxide monitoring: A randomized clinical trial.
To observe the effect of different fresh gas flows (FGF) on carboxyhemoglobin (COHb) levels non-invasively and continuously and to determine the contribution of the smoking status to intraoperative carbon monoxide (CO) accumulation and respiratory complications. ⋯ If the CO2 absorbent is properly preserved in patients who are administered LFA, there will be no risk of CO accumulation even in chronic smokers.ClinicalTrials.gov REG. No.: NCT04832256.

To find any correlation between the clinical response as per International Working Myeloma Group (IWMG) response criteria and the radiological response at the end of treatment. ⋯ Although we did not find a statistically significant correlation between the response versus metabolic activity and the number of bone/bone marrow lesions, however, our study was limited by the absence of clear criteria for defining disease response in PET/CT in MM patients. Further prospective analysis would be needed to establish a defined criterion.
