Gestational diabetes mellitus (GDM) is a risk factor for abnormal heart development. Previous work showed that a decrease of myocardial cells and an increase of apoptotic cells leading to heart defects under hyperglycemia, and many genes and protein have been found to play important roles in cardiomyocyte apoptosis. However, there are still many blind nodes in HG-induced cardiac apoptosis. Our study showed that down-regulation of GAB1 occurred concurrently with HG-induced cardiomyocytes apoptosis and in the heart tissues of offspring of diabetic rats in vitro and in vivo...

Cardiovascular complications induced by high fat are one of the most challenging health problems presently. Oxidative stress, inflammation and fibrosis are major components included in the pathology of diabetic cardiomyopathy. Nuclear factor erythroid 2-related factor 2 (Nrf2) has been reported as an essential therapeutic target in various diseases for its induction of anti-oxidant enzymes, and other protective enzymes. Additionally, a number of Nrf2 activators showed strong anti-inflammatory properties. In the study, we calculated the Nrf2-dependent anti-oxidant, anti-inflammatory and anti-fibrosis effects of chrysophanol in high fat diet-induced diabetic heart injury...

Diabetic cardiomyopathy has been systematically associated with compromised mitochondrial energetics and increased generation of reactive oxygen species (ROS) that underlie its progression to heart failure. Methylene blue is a redox-drug with reported protective effects mainly on brain mitochondria. The present study was purported to characterize the effects of acute administration of methylene blue on mitochondrial respiration, H2O2 production, and calcium sensitivity in rat heart mitochondria isolated from healthy and 2 months (streptozotocin-induced) diabetic rats...

Machine learning is becoming a popular and important approach in the field of medical research. In this study, we investigate the relative performance of various machine learning methods such as Decision Tree, Naïve Bayes, Logistic Regression, Logistic Model Tree and Random Forests for predicting incident diabetes using medical records of cardiorespiratory fitness. In addition, we apply different techniques to uncover potential predictors of diabetes. This FIT project study used data of 32,555 patients who are free of any known coronary artery disease or heart failure who underwent clinician-referred exercise treadmill stress testing at Henry Ford Health Systems between 1991 and 2009 and had a complete 5-year follow-up...

Previous studies indicate a preliminary association between age and circadian blood pressure (BP) variation. This association would be affected by confounding factors in real-world populations. The authors investigated whether this is a convincingly independent association in a real-world population of adults with hypertension. Clinical data and findings of 24-hour ambulatory BP monitoring were obtained from 297 consecutive adults with hypertension (60.19±0.77 years). BP dipping patterns were categorized based on the percentage of nocturnal BP drop...

BACKGROUND: Disability-adjusted life years (DALYs) provide a summary measure of health and can be a critical input to guide health systems, investments, and priority-setting in Ethiopia. We aimed to determine the leading causes of premature mortality and disability using DALYs and describe the relative burden of disease and injuries in Ethiopia. METHODS: We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015) for non-fatal disease burden, cause-specific mortality, and all-cause mortality to derive age-standardized DALYs by sex for Ethiopia for each year...

OBJECTIVE: Most studies have used cardiovascular and cerebrovascular disease (CVD) end-points to measure the effect of continuous positive airway pressure (CPAP), but pre-diagnostic morbidities involve a range of comorbidities that may influence the consequences of obstructive sleep apnea (OSA). We therefore aimed to evaluate all-cause total mortality after a diagnosis of OSA, the effect of CPAP in women and men, and the potential effect of major comorbidities. METHODS: We used national registry data as a historical cohort and included 22,135 OSA patients aged 20 years or more with comorbidity data three years before diagnosis and follow-up morbidity and mortality over a period of 17 years...
