Heart rate recovery at 1min (HRR1) is a strong predictor of all-cause mortality. The effects of statins on the autonomic nervous system may account for their beneficial effects in survival. Our aim was to determine if statin therapy improves heart rate recovery in hypercholesterolemic patients with type 2 diabetes mellitus. Thirty type 2 diabetic patients without known coronary artery disease and low density lipoprotein cholesterol>100mg/dl and 30 age and sex matched non-diabetic controls were included in a prospective study. Patients with diabetes were treated with simvastatin 40mg/day for 1 year. No lipid-lowering therapy was administered to the control group. Exercise testing with 2min cool-down period was performed at baseline, 6, 12 weeks and at 1 year. The diabetics had significantly lower HRR1 compared with non-diabetics at baseline (19.2+/-5.4bpm versus 24.2+/-4bpm, p<0.0001). Simvastatin therapy significantly improved HRR1 after 12 weeks compared to baseline (19.2+/-5.4bpm versus 24+/-5bpm, p<0.0001) and this improvement remained significant at 1 year (26+/-4.4bpm, p<0.0001 compared to baseline). HRR1 did not change in the control group (p=0.39 by ANOVA). This study demonstrates that treatment with simvastatin might improve the attenuated heart rate recovery of diabetic subjects. In patients with diabetes, the mortality benefit provided by statins might involve their effects on the autonomic nervous system.

No FDA-approved medications for methamphetamine (MA) use disorder (MUD) are available. Suvorexant (SUVO), a dual orexin receptor antagonist that is FDA approved for insomnia treatment, reduces MA self-administration and MA-induced reinstatement responding in preclinical studies. SUVO may also reduce MA use by targeting substance use risk factors, including insomnia, stress, cue reactivity, and craving.

Study Objectives: Isolated REM sleep behavior disorder (iRBD) is recognized as a prodromal stage of alpha-synucleinopathies. Predicting phenoconversion in iRBD patients remains a key challenge. We aimed to investigate whether event-related potentials (ERPs) recorded during visuospatial attention task can serve as predictors of phenoconversion in iRBD patients.

Backgrounds: Due to the high mortality and hospitalization rate in chronic heart failure (HF), it is of great significance to study myocardial nutrition conditions. Amino acids (AAs) are essential nutrient metabolites for cell development and survival. This study aims to investigate the associations and prognostic value of plasma branched-chain amino acid/aromatic amino acid ratio (Fischer's ratio, FR) in patients with left ventricular ejection fraction (LVEF) ≤ 50%.

Introduction: Non-cancer deaths are now becoming a significant threat to the health of cancer patients. Death from stomach and duodenal ulcer is linked to cancer due to the side effects of treatment and its pathogenesis. However, guidelines for identifying cancer patients at the highest risk of death from stomach and duodenal ulcer remain unclear.

We investigated the interplay of cardiovascular autonomic and inflammatory profiles in persons with extreme longevity (PEL), their direct offsprings (DO), and a group of controls matched for age and sex with the DO. Cardiac autonomic control was assessed through the heart rate variability (HRV) using spectral and symbolic analysis. The plasma concentration and gene expression of interleukin (IL)-10, IL-6, and TNF-α were quantified.
