Innovations in Undergraduate Research Training Through Multisite Collaborative Programming: American Heart Association Summer Undergraduate Research Experience Syndicate.

Background To support diversity in biomedical science, the American Heart Association launched the Supporting Undergraduate Research Experiences for undergraduate students from underrepresented backgrounds to provide mentorship and high-level exposure at 5 leading medical institutions. Here we describe the initial formation of the partnership and the alteration made in response to the program to accommodate COVID-19 safety precautions. Methods and Results We outline how programming shifted from local, in-person programming in the summer of 2019 to a collaborative, mainly virtual curriculum in 2020 using students' self-reported before and after surveys from both 2019 (n=33) and 2020 (n=42).

Splanchnic Venous Compression Enhances the Effects of ß-Blockade in the Treatment of Postural Tachycardia Syndrome.

Background Splanchnic venous pooling induced by upright posture triggers a compensatory increase in heart rate (HR), a response that is exaggerated in patients with postural tachycardia syndrome. To assess whether abdominal compression attenuates orthostatic tachycardia and improves symptoms, 18 postural tachycardia syndrome patients (32±2 years) were randomized to receive either abdominal compression (40 mm Hg applied with an inflatable binder ≈2 minutes before standing) or propranolol (20 mg) in a placebo-controlled, crossover study. Methods and Results Systolic blood pressure, HR, and symptoms were assessed while seated and standing, before and 2 hours postdrug.
