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 determine the level of awareness of medical law among healthcare practitioners and to identify factors that influence that level of awareness in Saudi Arabia. ⋯ Awareness of medical law among healthcare practitioners is limited in Saudi Arabia. Professional medico-legal education should be part of required competencies for undergraduate and postgraduate levels of medical education. Health care practitioners must be educated with laws and regulations of practicing health professions in the country.

To assess the effect of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection on erythropoiesis and red blood cells (RBC) surface markers by evaluating erythroid progenitor cells (CD [cluster of differentiation]71+/CD235a+) and RBC surface markers (CD235a and CD36), together with various hematological parameters. ⋯ Severe acute respiratory syndrome coronavirus-2 promoted the expansion of erythroid progenitors in the peripheral blood of COVID-19 patients. In addition, the expression of RBC surface markers was higher in COVID-19 patients. The expansion of erythroid progenitors and alteration of RBC surface markers can contribute to erythrocytopathies observed in severe COVID-19 patients and can therefore be used as prognostic factors.
