Most research to date has focused on epigenetic modifications in the nuclear genome, with little attention devoted to mitochondrial DNA (mtDNA). Placental mtDNA content has been shown to respond to environmental exposures that induce oxidative stress, including airborne particulate matter (PM). Damaged or non-functioning mitochondria are specifically degraded through mitophagy, exemplified by lower mtDNA content, and could be primed by ...

Background: Although the relation of salt intake with blood pressure (BP) is linear, it is U–shaped for mortality and cardiovascular disease (CVD). This individual-participant meta-analysis explored whether the relation of hypertension, death or CVD with 24-h urinary sodium excretion (UVNA) or sodium-to-potassium (UNAK) ratio was modified by birth weight. Methods: Families were randomly enrolled in the Flemish Study on Genes, Environment and ...

The Kidney Solid Organ Response Test (kSORT) blood gene expression assay was developed to noninvasively detect acute rejection (AR) after kidney transplantation. Its performance in a setting with natural disease prevalence has not been evaluated. A retrospective, multicenter cohort study was conducted across all single kidney transplant recipients, transplanted between 2011 and 2015, with samples within the first year after transplantation ...

OBJECTIVE Infant hydrocephalus is estimated to affect more than 100,000 new infants each year in sub-Saharan Africa (SSA). Bugando Medical Centre (BMC), a government-funded and patient cost-shared referral center, serves over 13 million people in the Lake and Western regions of Tanzania. The goals of this study were to characterize the infant population affected by hydrocephalus who presented to BMC and were treated with a ventriculoperitoneal ...

OBJECTIVES: Restrictive mitral valve annuloplasty combined with coronary artery bypass grafting is the treatment of choice for ischemic mitral regurgitation. Postoperative functional mitral stenosis and its potential impact on functional capacity remain the object of debate. The aim of this study was to assess functional and hemodynamic outcome at rest and during exercise in a population with ischemic mitral regurgitation after a standardized ...

Long-term follow-up of clinical trials of blood pressure-lowering medications has suggested a continuation of event reduction after study completion. We evaluated the persistence of mortality benefit of these agents after the end of clinical trials, when all of the patients were advised to take the same open-label therapy. We performed a meta-analysis of randomized clinical trials using blood pressure-lowering medications, used in patients with ...

BACKGROUND: In severely affected patients with catecholaminergic polymorphic ventricular tachycardia, beta-blockers are often insufficiently protective. The purpose of this study was to evaluate whether flecainide is associated with a lower incidence of arrhythmic events (AEs) when added to beta-blockers in a large cohort of patients with catecholaminergic polymorphic ventricular tachycardia. METHODS: From 2 international registries, this ...

OBJECTIVES: This study sought to define the feasibility and utility of postmortem cardiac implantable electronic device (CIED) interrogation. BACKGROUND: The diagnostic yield of routine postmortem interrogation of CIEDs including pacemakers, defibrillators, and implantable loop recorders has not been established. METHODS: The study reviewed all CIED interrogations in deceased individuals undergoing medicolegal investigation of sudden or ...

IMPORTANCE The benefit of adjuvant chemotherapy after resection of pancreatic cancer following neoadjuvant combination treatment with folinic acid, fluorouracil, irinotecan, and oxaliplatin (FOLFIRINOX) is unclear. OBJECTIVE To assess the association of adjuvant chemotherapy with overall survival (OS) in patients after pancreatic cancer resection and neoadjuvant FOLFIRINOX treatment. DESIGN, SETTING, AND PARTICIPANTS This international, ...
