Food cravings are more prevalent and potentially problematic for many individuals with obesity. Initial evidence suggests that bariatric surgery has some short-term beneficial effects on cravings in adults, but little is known about the effect on adolescents or the trajectory beyond 6 months.The purpose of the present study was to determine the longitudinal effect of Roux-en-Y gastric bypass (RYGB)...
Alterations in autonomic nervous system activity (ANSA) participate in arrhythmogenesis but little information exists on the time course of such effects. To address the hypothesis that a window of opportunity exists during which preventive interventions could be employed, we examined the changes in heart rate (HR) and HR variability indices (HRVi), which reflect ANSA, prior to the onset of spontaneous...
Experimental and clinical observations support a role for sympathetic (SA) and parasympathetic (PA) activities in the genesis of ventricular tachyarrhythmias but studies in human patients (pts) have been inconsistent. We used heart rate (HR) variability (HRV) analysis in the frequency domain (FD) to address the hypothesis that short-term changes in SA and PA precede the onset of spontaneous sustained...
