BACKGROUND: Relationships between early kidney disease, neurocognitive function, and brain anatomy are poorly defined in African Americans with type 2 diabetes mellitus (T2DM). STUDY DESIGN: Cross-sectional associations were assessed between cerebral anatomy and cognitive performance with estimated glomerular filtration rate (eGFR) and urine albumin-creatinine ratio (UACR) in African Americans with T2DM. SETTING & PARTICIPANTS: African Americans with cognitive testing and cerebral magnetic resonance imaging (MRI) in the African American-Diabetes Heart Study Memory in Diabetes (AA-DHS MIND; n=512; 480 with MRI) and Action to Control Cardiovascular Risk in Diabetes (ACCORD) MIND (n=484; 104 with MRI) studies...

BACKGROUND: Heart failure (HF) is associated with chronic sympathetic activation. Renal denervation (RDN) aims to reduce sympathetic activity by ablating the renal sympathetic nerves. We investigated the effect of RDN in patients with chronic HF and concurrent renal dysfunction, in a prospective, multicenter, single-arm feasibility study. METHODS AND RESULTS: Thirty-nine patients with chronic systolic HF (left ventricular ejection fraction [LVEF] <40%, New York Heart Association class II-III,) and renal impairment (estimated glomerular filtration rate [eGFR; assessed with Modification of Diet in Renal Disease equation] <75 mL/min/1...

Background: More than 90 tyrosine kinases have been implicated in the pathogenesis of malignant transformation and tumor angiogenesis. Tyrosine kinase inhibitors (TKIs) have emerged as effective therapies in treating cancer by exploiting this kinase dependency. The TKI erlotinib targets the epidermal growth factor receptor (EGFR), whereas sunitinib targets primarily vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor (PDGFR).TKIs that impact the function of non-malignant cells and have on- and off-target toxicities, including cardiotoxicities...

BACKGROUND: Acute kidney injury (AKI) is associated with high morbidity and mortality, and may lead to chronic kidney disease (CKD). Traditional serum biomarkers for acute and chronic renal dysfunction are insensitive and nonspecific. While urinary kidney injury molecule-1 (KIM-1) is a sensitive and specific measure of kidney tubular injury, it is difficult to obtain in acute settings. Thus, our objective was to develop a highly sensitive immunoassay for plasma KIM-1. METHODS: A novel plasma KIM-1 immunoassay was developed using Single Molecule Counting technology (SMC)...

INTRODUCTION: The assessment of the amount of urine produced by the dose of administered diuretic has been proposed as the main signal of interest in diuretic responsiveness - diuretic efficiency (DE). The main aim of our study is to determine if a low DE is associated with 180-day all-cause mortality (ACM). METHODS: During a 3-year period, we retrospectively studied patients with acutely decompensated heart failure (ADHF) and respiratory insufficiency admitted to the emergency room of a tertiary university hospital in Porto, Portugal...

BACKGROUND/AIMS: Spironolactone may be hazardous in heart failure (HF) patients with renal dysfunction due to risk of hyperkalemia and worsened renal function. We aimed to evaluate the effect of spironolactone on all-cause mortality in HF outpatients with renal dysfunction in a propensity-score-matched study. METHODS: A total of 2,077 patients from the Norwegian Heart Failure Registry with renal dysfunction (eGFR <60 mL/min/1.73 m(2)) not treated with spironolactone at the first visit at the HF clinic were eligible for the study...

BACKGROUND AND AIMS: Tumor necrosis factor receptor type 1 (TNFR1) is associated with kidney disease and mortality risk in various populations. Whether or not kidney function mediates mortality risk is unknown. We evaluated associations of TNFR1 levels with measures of kidney function, cardiovascular events, and mortality in a population of veterans with stable ischemic heart disease. METHODS: TNFR1 was measured from baseline serum samples in the Heart and Soul Study; elevated levels were defined by the highest quartile (Q4, >3...

Shaad M Ahmad
Signal transduction through multiple distinct pathways regulates and orchestrates the numerous biological processes comprising heart development. This review outlines the roles of the FGFR, EGFR, Wnt, BMP, Notch, Hedgehog, Slit/Robo and other signaling pathways during four sequential phases of Drosophila cardiogenesis-mesoderm migration, cardiac mesoderm establishment, differentiation of the cardiac mesoderm into distinct cardiac cell types, and morphogenesis of the heart and its lumen based on the proper positioning and cell shape changes of these differentiated cardiac cells-and illustrates how these same cardiogenic roles are conserved in vertebrates...

Background: kidney function declines in older adults and physical activity levels are low. We investigated whether higher levels of physical activity and lower levels of sedentary behaviour were associated with lower odds of low kidney function in older men. Methods: cross-sectional study of 1,352 men from the British Regional Heart Study, mean (standard deviation) age 78.5 (4.6) year. Physical activity and sedentary behaviour were measured using Actigraph GT3X accelerometers...

BACKGROUND: Metformin is the cornerstone of the pharmacological therapy for type 2 Diabetes (T2D). It belongs to the biguanide class of drugs and it improves hepatic insulin resistance and enhances GLP-1 and peptide YY secretion. Although being considered safe regarding hypoglycemic risk, renal dysfunction remains the main obstacle to its use due to the underlying risk of lactic acidosis. In the recent past many authors used creatinine values as the decisive marker when it came to choose between pharmacological agents in DM...

Hypertension (HT) is the most important risk factor for cardiovascular diseases. Over the past 25 years, the number of individuals with hypertension and the estimated associated deaths has increased substantially. There have been great debates in the past few years on the blood pressure (BP) targets. The 2013 European Society of Hypertension and European Society of Cardiology HT guidelines suggested a unified systolic BP target of 140 mmHg for both high-risk and low-risk patients. The 2014 Joint National Committee report further raised the systolic BP targets to 150 mmHg for those aged ≥ 60 years, including patients with stroke or coronary heart disease, and raised the systolic BP target to 140 mmHg for diabetes...
