    Strong inward rectifier K(+) (Kir2) channels primarily maintain normal resting membrane potential of cardiomyocytes. In sub-physiological extracellular K(+) concentrations or pathological hypokalaemia, human cardiomyocytes show both hyperpolarized and depolarized resting membrane potentials; these depolarized potentials cause cardiac arrhythmia; however, the underlying mechanism is unknown. Here we show that Kir2. Read More

    Hypertension and cardiac arrhythmias: executive summary of a consensus document from the European Heart Rhythm Association (EHRA) and ESC Council on Hypertension, endorsed by the Heart Rhythm Society (HRS), Asia-Pacific Heart Rhythm Society (APHRS), and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE).

    Hypertension (HTN) is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease (CAD), stroke, peripheral artery disease and chronic renal failure. Hypertensive heart disease can manifest as many types of cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in HTN patients, especially in those with left ventricular hypertrophy (LVH), CAD, or HF. Read More

    Background: The American Society for Parenteral and Enteral Nutrition Adult Nutrition Support Core Curriculum describes clinical conditions that warrant cautious use of parenteral nutrition (CCWCPN). The Core Curriculum authors acknowledge there is no evidence for specific criteria suggested for the clinical conditions. Consequently, the purpose of this study was to determine the impact of a baseline CCWCPN on the development of subsequent metabolic complications in patients receiving parenteral nutrition (PN).

    We describe a case of apparent mineralocorticoid excess (AME) secondary to posaconazole and suggest the biochemical mechanism. Clinical and laboratory investigation confirmed 11β-hydroxysteroid dehydrogenase inhibition and withholding therapy led to a resolution of all clinical and laboratory abnormalities. A lower dose of posaconazole was later restarted and avoided recurrence of this syndrome. Read More

    Study Objectives: Sudden unexpected death during sleep (SUDS) is the most common cause of death in patients with familial dysautonomia, an autosomal recessive disease characterized by sensory and autonomic dysfunction. It remains unknown what causes SUDS in these patients and who is at highest risk. We tested the hypothesis that SUDS in FD is linked to sleep-disordered breathing. Read More
