The Stroll Safe Randomized Controlled Trial: Program Effects on Falls Self-Efficacy.

Objective: Outdoor falls can negatively impact the health and functional abilities of community-dwelling older adults. Although there are existing evidence-based programs for falls prevention, none specifically target outdoor falls. To fill this gap in research and practice, the Stroll Safe program was developed.

Point-of-care lung ultrasound for continuous positive airway pressure discontinuation in preterm infants.

Objective: To determine if the lung ultrasound score (LUS) is predictive of successful continuous positive airway pressure (CPAP) discontinuation in preterm neonates born <32 weeks' gestation with history of respiratory distress syndrome.

Study Design: Retrospective study of preterm infants requiring CPAP. Univariate and multivariate logistic regression performed to formulate a predictive score using clinical variables with and without LUS.

Longitudinal study of root resorption on incisors caused by impacted maxillary canines-a clinical and cone beam CT assessment.

Objective: To evaluate the long-term status of incisors with canine-induced root resorption (CIRR).

Materials And Methods: Subjects with impacted maxillary canines (IMC) and persisting incisors with CIRR examined with cone beam computed tomography (CBCT), diagnosed ≥ 5 years earlier, were recalled. The resorption grade in the horizontal and vertical plane was assessed on CBCT images at baseline (T0) and follow-up (T1).

Benchmarking commercial healthcare claims data.

Importance: Commercial healthcare claims datasets represent a sample of the US population that is biased along socioeconomic/demographic lines; depending on the target population of interest, results derived from these datasets may not generalize. Rigorous comparisons of claims-derived results to ground-truth data that quantify this bias are lacking.

Objectives: (1) To quantify the extent and variation of the bias associated with commercial healthcare claims data with respect to different target populations; (2) To evaluate how socioeconomic/demographic factors may explain the magnitude of the bias.

Metabolic RNA labeling in non-engineered cells following spontaneous uptake of fluorescent nucleoside phosphate analogues.

RNA and its building blocks play central roles in biology and have become increasingly important as therapeutic agents and targets. Hence, probing and understanding their dynamics in cells is important. Fluorescence microscopy offers live-cell spatiotemporal monitoring but requires labels.
