Intercessory prayer (praying for others) has been a common response to sickness millennia, but it received little scientific attention. The positive findings of previous controlled trial intercessory have yet be replicated.To determine whether remote, hospitalized, cardiac patients will reduce overall adverse events and length stay.Randomized, controlled, double-blind, prospective, parallel-group trial.Private, university-associated hospital.Nine hundred ninety consecutive who were newly...

Background Our goal was to investigate the role of physical exercise protect brain health as we age, including potential mitigate Alzheimer’s-related pathology. We assessed effect 52 weeks a supervised aerobic program on amyloid accumulation, cognitive performance, and volume in cognitively normal older adults with elevated sub-threshold levels cerebral measured by PET imaging. Methods findings This 52-week randomized controlled trial compared effects 150 minutes per week vs. education...

Background— This trial tested the effects of multidisciplinary group clinic appointments on primary outcome time to first heart failure (HF) rehospitalization or death. Methods and Results— HF patients (n=198) were randomly assigned standard care plus clinics. The intervention consisted 4 weekly 1 booster at month 6, where professionals engaged in self-management skills. Data collected prospectively for 12 months beginning after completion (2 post randomization). was associated with greater...

Mitochondria are important organelles referred to as cellular powerhouses for their unique properties of energy production. With many pathologic conditions and aging, mitochondrial function declines, there is a reduction in the production adenosine triphosphate. The carrying molecule generated by respiration pentose phosphate pathway, an alternative pathway glucose metabolism. D-ribose naturally occurring monosaccharide found cells particularly mitochondria essential Without sufficient...

Objectives: We sought to evaluate the influence of single‐ versus dual‐chamber implantable cardioverter defibrillators (ICDs) on occurrence heart failure and mortality as well appropriate inappropriate ICD therapy in Multicenter Automatic Defibrillator Implantation Trial II (MADIT‐II). Background: In MADIT‐II, patients with a prior myocardial infarction ejection fraction ≤0.30 was associated 31% reduction risk when compared conventionally treated patients. An unexpected finding an increased...

Abstract Background Early markers of diabetic autonomic neuropathy (DAN) in an electrocardiogram (ECG) include elevated R wave amplitudes, widening QT c intervals and decreased heart rate variability (HRV). The severity DAN has a direct relationship with mortality risk. Aerobic exercise training is common recommendation for the delay possible reversal cardiac dysfunction. Limited research exists on ECG measures evaluation aerobic Zucker Diabetic Fatty (ZDF) rat, model type 2 diabetes....
