Role of caffeine in slowing progression of myopia: 1-year results from a prospective, longitudinal clinical trial.

Purpose: To determine the role of topical caffeine in slowing progression of myopia, both as a standalone treatment and in combination with atropine.

Methods: In a prospective, randomized, dispensing clinical trial, 96 children with myopia, aged 6-13 years, spherical equivalent (SE) from -0.50 diopters (D) to -6.

Shortened SARS-CoV-2 viral RNA shedding in saliva during early Omicron compared to wild-type pandemic phase.

This study compared the dynamics of SARS-CoV-2 viral shedding in saliva between wild-type virus-infected and Omicron-infected household cohorts. Pre-existing immunity in participants likely shortens the viral RNA shedding duration and lowers viral load peaks. Frequent saliva sampling can be a convenient tool to study viral load dynamics.

Evaluation of artificial intelligence-based autosegmentation for a high-performance cone-beam computed tomography imaging system in the pelvic region.

Background And Purpose: A novel ring-gantry cone-beam computed tomography (CBCT) imaging system shows improved image quality compared to its conventional version, but its effect on autosegmentation is unknown. This study evaluates the impact of this high-performance CBCT on autosegmentation performance, inter-observer variability, contour correction times and delineation confidence, compared to the conventional CBCT.

Materials And Methods: Twenty prostate cancer patients were enrolled in this prospective clinical study.
