Background: Palmar hyperhidrosis has been associated with an increased activity of the sympathetic nervous system. The objective of this study was to assess the immediate and long-term effects of endoscopic transthoracic sympathicotomy on the autonomic modulation of the heart rate in patients with palmar hyperhidrosis.
Methods: Power spectrum analysis of heart rate variability in the lying position and after passive tilt to the upright position was performed in thirteen patients the day before and after sympathicotomy. A follow-up recording was performed in ten patients approximately six months later. Recordings from 26 healthy subjects were used as a reference group.
Findings: The patients had a tendency to higher power of the low-frequency (LF: 0.04-0.15 Hz) and high-frequency (HF; above 0.15 Hz) components than controls in the upright position. After sympathicotomy LF power was reduced, but HF power was unchanged. At follow-up LF power remained at a lower level, but now HF power was reduced.
Interpretation: Patients with palmar hyperhidrosis have a sympathetic overactivity but also a compensatory high parasympathetic activity. Sympathicotomy results in an initial sympathovagal imbalance with a parasympathetic predominance, which is restored on a long-term basis.

Subvalvular aortic stenosis typically manifests at a young age and rarely presents in adulthood. It may cause left ventricular outflow tract stenosis, which requires surgical treatment in severe cases. The coexistence of discrete subvalvular aortic stenosis and quadricuspid aortic valve is a highly unusual finding.

Acute exercise is linked to memory improvement. Several mediators may influence the effect of exercise such as the type of exercise (aerobic exercise, muscle stretching). The primary aim was to analyze memory outcomes after a 20-min bout of aerobic exercise or muscle stretching.

Spinal cord injury and stroke are neurological disorders that lead to aerobic deconditioning and increased likelihood of cardiovascular disease. Sessions of at least 20 minutes of moderate-to-vigorous intensity exercise is recommended but decreased mobility limits engagement in such exercise. The aim of the study was to assess whether individuals can achieve exercise recommendations with the assistance of an end-effector robot assisted gait trainer (E-RAGT).

Background: Our remote patient monitoring (RPM) program for adult cardiac surgery patients aims to remove barriers to access, provide continuity of expert care, and increase their time-at-home. The RPM program integrates novel biosensors, an application for audiovisual visits, messaging, biometric data tracking, patient-reported outcomes, and scheduling with the aim of reducing postoperative length of stay and 30-day readmissions, while simultaneously increasing the rate of patients discharged to home.
Methods: Our institutional database was utilized for this retrospective review of 1000 consecutive RPM patients who underwent coronary artery bypass, valve, and coronary artery bypass + valve, at 3 hospitals from July 2019 through April 2023.
