This three-month prospective cohort study evaluated the efficacy of a respiratory-responsive vocal biomarker (RRVB) accessible via smartphone application as a real-time monitoring tool for asthma exacerbations. The study enrolled 84 asthma patients who provided daily six-second vocal samples to generate RRVB scores, assessing the biomarker’s ability to predict asthma exacerbations and respiratory states defined by peak expiratory flow and self-reported well-being using risk ratios and confidence intervals.

This study examined community reactions to a self-management toolkit for patients with upper respiratory symptoms to inform mobile e-health app development, based on the "4R" (Right Information, Right Care, Right Patient, Right Time) care planning and management model. The research involved distributing the 4R Cold, Flu and COVID-19 Information Tool along with evaluation surveys through multiple channels to assess community perceptions of the toolkit’s accessibility, preferences for sharing symptoms with clinicians, social media use and e-health literacy among 106 Bronx residents.

This prospective, observational study evaluated the efficacy of virtual reality (VR) hemorrhage training compared to traditional in-person instruction for tourniquet application skills among 53 emergency medicine residents at a Level I trauma center. Participants were randomly assigned to either control or VR training groups and assessed using the National Registry Hemorrhage Control Skills Lab rubric immediately after training and at 3-month retention testing, measuring successful tourniquet placement and time to completion.
