The aim of this study was to determine the effect of caffeine intake on overall basketball performance in experienced players. A double-blind, placebo-controlled, randomized experimental design was used for this investigation. In two different sessions separated by one week, 20 experienced basketball players ingested 3 mg of caffeine/kg of body mass or a placebo. After 60 min, participants perform...

Polygenic loading for major depression is associated with specific medical comorbidity.

Major depressive disorder frequently co-occurs with medical disorders, raising the possibility of shared genetic liability. Recent identification of 15 novel genetic loci associated with depression allows direct investigation of this question. In cohorts of individuals participating in biobanks at two academic medical centers, we calculated polygenic loading for risk loci reported to be associated...

Diabetes-mediated myelopoiesis and the relationship to cardiovascular risk.

Diabetes is the greatest risk factor for the development of cardiovascular disease, which, in turn, is the most prevalent cause of mortality and morbidity in diabetics. These patients have elevations in inflammatory monocytes, a factor consistently reported to drive the development of atherosclerosis. In preclinical models of both type 1 and type 2 diabetes, studies have demonstrated that the incr...

Clostridium difficile Infection in Intestinal Transplant Recipients.

Clostridium difficile infection (CDI) is a common complication among solid organ transplant (SOT) recipients with an estimated incidence of 7-31% for lung recipients, 8-15% for heart, 3-19% for liver, 9% for intestinal, 4-16% for kidney and 2-8% for pancreas-kidney recipients (1) and it is associated with increased mortality (2). There is limited data on CDI in intestinal transplant (ITx) recipien...

Retinal vessel morphology in rheumatoid arthritis: association with systemic inflammation, subclinical atherosclerosis and cardiovascular risk.

Quantification of retinal vessel morphology has emerged as a marker of cardiovascular health. We examined retinal microvascular diameters in RA, particularly in regard with systemic inflammation, subclinical atherosclerosis and cardiovascular risk.

Vitamin D status, serum lipid concentrations, and vitamin D receptor (VDR) gene polymorphisms in Familial Mediterranean fever.

Vitamin D (VitD) is critical for the regulation of inflammatory processes, and VitD deficiency has been linked to several chronic inflammatory disorders. We aimed to investigate the concentrations of serum 25(OH)D3, lipid parameters, and three known VDR polymorphisms (BsmI, FokI, and TaqI) in patients with Familial Mediterranean fever (FMF), an autosomal recessive autoinflammatory disease. The stu...

Early effects of renal replacement therapy on cardiovascular comorbidity in children with end-stage kidney disease: findings from the 4C-T Study.

The early impact of renal transplantation on subclinical cardiovascular measures in pediatric patients has not been widely investigated. This analysis is performed for pediatric patients participating in the prospective 4C study and focuses on the early effects of RRT modality on cardiovascular comorbidity in patients receiving a preemptive transplant or started on dialysis.

Sequential and urgent coronary artery bypass surgery followed by kidney transplantation in a highly sensitized patient with unstable angina.

Critical developmental windows for morphology and hematology revealed by intermittent and continuous hypoxic incubation in embryos of quail (Coturnix coturnix).

Hypoxia during embryonic growth in embryos is frequently a powerful determinant of development, but at least in avian embryos the effects appear to show considerable intra- and inter-specific variation. We hypothesized that some of this variation may arise from different protocols that may or may not result in exposure during the embryo's critical window for hypoxic effects. To test this hypothesi...

The novel mineralocorticoid receptor antagonist finerenone attenuates neointima formation after vascular injury.

The novel nonsteroidal mineralocorticoid receptor (MR) antagonist finerenone holds promise to be safe and efficient in the treatment of patients with heart failure and/or chronic kidney disease. However, its effects on vascular function remain elusive.

Skin perfusion pressure as an indicator of tissue perfusion in valvular heart surgery: Preliminary results from a prospective, observational study.

Hemodynamic management aims to provide adequate tissue perfusion, which is often altered during cardiac surgery with cardiopulmonary bypass (CPB). We evaluated whether skin perfusion pressure (SPP) can be used for monitoring of adequacy of tissue perfusion in patients undergoing valvular heart surgery. Seventy-two patients undergoing valve replacement were enrolled. SPP and serum lactate level wer...

Depression recognition according to heart rate variability using Bayesian Networks.

Doctors mainly use scale tests and subjective judgment in the clinical diagnosis of depression. Researches have demonstrated that depression is associated with the dysfunction of the autonomic nervous system (ANS), where its modulation can be evaluated by heart rate variability (HRV). Depression patients have lower HRV than healthy subjects. Therefore, HRV may be used to distinguish depression pat...

Ambient temperature and risk of cardiovascular events at labor and delivery: A case-crossover study.

Extreme ambient temperatures are linked to cardiac events in the general population, but this relationship is unclear among pregnant women. We estimated the associations and attributable risk between ambient temperature and the risk of cardiovascular event at labor/delivery, and investigated whether these associations vary by maternal race/ethnicity.

Cardiovascular Responses to Resistance Exercise Performed with Large and Small Muscle Mass.

Prior research about the effects of the amount of exercised muscle mass upon cardiovascular responses (CVR) has neglected a potential bias related to total exercise and concentric/eccentric duration. Autonomic responses and perceived exertion (RPE) were compared in resistance exercises performed with larger and smaller muscle mass and matched for total exercise and concentric/eccentric duration. T...

Exercise training dose differentially alters muscle and heart capillary density and metabolic functions in an obese rat with metabolic syndrome.

We evaluated the effect of frequency, duration and intensity of exercise training on metabolic parameters and structural capillary density in obese rats with metabolic syndrome (MS). Wistar-Kyoto rats were fed a either standard commercial diet (CON) or high-fat diet (HFD). Animals that received the HFD were randomly separated into either a sedentary (SED) group or 8 different exercise groups that ...

Does an observer's empathy influence my pain? Effect of perceived empathetic or unempathetic support in a pain test.

The physiological and behavioural effects of empathy for other's pain have been widely investigated, while the opposite situation, i.e. the influence on one's pain of empathetic feedback from others, remains largely unexplored. Here, we assessed whether and how empathetic and unempathetic comments from observers modulate pain and associated vegetative reactions. In Study 1, conversations between o...

Pre-eclampsia is primarily a placental disorder: AGAINST: Pre-eclampsia: the heart matters.

Clinical assessment of coronary arteries in Kawasaki disease: Focus on echocardiographic assessment.

Echocardiography is an excellent noninvasive imaging modality for evaluation and follow-up of cardiac lesions, especially coronary artery changes occurring as a result of Kawasaki disease. The information obtained has prognostic implications and can be complemented with other modes of imaging for risk stratification and optimization of both medical and interventional therapy. The aim of this artic...

Simplified and age-appropriate recommendations for added sugars in children.

Excess sugar intake increases risk for obesity and related comorbidities among children. The World Health Organization (WHO), American Heart Association (AHA) and the 2015 USDA dietary recommendations have proposed guidelines for added sugar intake to reduce risk for disease. WHO and USDA recommendations are presented as a percentage of daily calories from added sugar. This approach is not easily ...

Chronic kidney disease and incident apparent treatment-resistant hypertension among blacks: Data from the Jackson Heart Study.

It is unclear whether black patients with chronic kidney disease (CKD) vs those without CKD who take antihypertensive medication have an increased risk for apparent treatment-resistant hypertension (aTRH). The authors analyzed 1741 Jackson Heart Study participants without aTRH taking antihypertensive medication at baseline. aTRH was defined as uncontrolled blood pressure while taking three antihyp...

Clinical practices and attitudes regarding the diagnosis and management of heart failure: findings from the CORE Needs Assessment Survey.

CORE is a continuing medical education initiative designed to support the evidence-based management of heart failure (HF) in the primary and secondary care settings. The goal of the CORE Needs Assessment Survey is to describe current clinical practice patterns and attitudes among global stakeholders in HF care.

Ventricular assist device use in single ventricle congenital heart disease.

As VAD have become an effective therapy for end-stage heart failure, their application in congenital heart disease has increased. Single ventricle congenital heart disease introduces unique physiologic challenges for VAD use.
