Arousal and the way it is coped with are relevant to the emergence of psychotic symptoms. Heart rate variability (HRV) stems from autonomic responses to environmental demands such as stress and is an index of physiological arousal, adaptability, and homeostatic reflexes forming autonomic balance. A randomized-controlled between-subjects trial that compared HRV-biofeedback (BF) to an active relaxation and to a waiting control condition was conducted in a sample with attenuated subclinical psychotic symptoms (N = 84)...

BACKGROUND: Preconditioning stimuli conducted in remote organs can protect the heart against subsequent ischemic injury, but effects on arrhythmogenesis and sudden cardiac death (SCD) are unclear. Here, we investigated the effect of remote liver ischemia preconditioning (RLIPC) on ischemia/reperfusion (I/R)-induced cardiac arrhythmia and sudden cardiac death (SCD) in vivo, and determined the potential role of ERK/GSK-3βsignaling. METHODS/RESULTS: Male Sprague Dawley rats were randomized to sham-operated, control, or RLIPC groups...

PURPOSE: Exercise increases core body temperature (TC) due to metabolic heat production. However, the exercise-induced release of inflammatory cytokines including interleukin-6 may also contribute to the rise in TC by increasing the hypothalamic temperature setpoint. We aimed to investigate whether the exercise-induced increase in TC is partly caused by an altered hypothalamic temperature setpoint. METHODS: 15 healthy, active male subjects aged 36±14 years were recruited...

BACKGROUND: Impaired functional capacity is a hallmark of patients with heart failure with preserved ejection fraction (HFpEF). Despite the association of HFpEF with reduced myocardial compliance attributed to fibrosis, spironolactone has not been shown to alter outcomes-perhaps reflecting the heterogeneity of underlying pathological mechanisms. OBJECTIVES: The authors sought to identify improvement in exercise capacity with spironolactone in the subset of patients with HFpEF with exercise-induced increase in ratio between early mitral inflow velocity and mitral annular early diastolic velocity (E/e') reflecting elevation of left ventricular (LV) filling pressure...

BACKGROUND: This is an updated version of the original Cochrane review published in Issue 1, 2010, on 'Benzodiazepines for the relief of breathlessness in advanced malignant and non-malignant diseases in adults'. Breathlessness is one of the most common symptoms experienced in the advanced stages of malignant and non-malignant disease. Benzodiazepines are widely used for the relief of breathlessness in advanced diseases and are regularly recommended in the literature. At the time of the previously published Cochrane review, there was no evidence for a beneficial effect of benzodiazepines for the relief of breathlessness in people with advanced cancer and chronic obstructive pulmonary disease (COPD)...

Arterial stiffness increases after glucose ingestion. Acute low- and moderate-intensity aerobic exercise decreases arterial stiffness. However, the acute effects of 30 min of cycling at low- and moderate-intensity [25% (LE trial) and 65% (ME trial) peak oxygen uptake, respectively] on arterial stiffness at 30, 60 and 120 min of a postexercise glucose ingestion. Ten healthy young men (age, 22·4 ± 0·5 years) performed LE and ME trials on separate days in a randomized controlled crossover fashion. Carotid-femoral (aortic) pulse wave velocity (PWV), femoral-ankle (leg) PWV, carotid augmentation index (AIx) and carotid blood pressure (BP) (applanation tonometry), brachial and ankle BP (oscillometric device), heart rate (HR) (electrocardiography), blood glucose (UV-hexokinase method) and blood insulin (CLEIA method) levels were measured at before (baseline) and at 30, 60 and 120 min after the 75-g OGTT...

Acute myocardial infarction (MI) caused by ischemia is the most common cause of cardiac dysfunction. While growth factor therapy is promising, the retention in the highly vascularized myocardium is limited and prevents sustained activation needed for adequate cellular responses. Here, we demonstrated the use of polyethylene glycol-fibrinogen (PF) hydrogels for sustained dual delivery of vascular endothelial growth factor (VEGF) and angiopoietin-1 (ANG-1) to enhance myocardial repair and function. VEGF and ANG-1 were incorporated in PF hydrogels and their in vitro characteristics were studied...

BACKGROUND: In heart failure (HF), attention may be decreased because of lowered cerebral blood flow and increased attentional demands needed for self-care. OBJECTIVE: Guided by the Attention Restoration Theory, the objective was to test the efficacy of the natural restorative environment (NRE) intervention on improving attention and mood among HF patients and healthy adults. METHODS: A randomized crossover pilot study was conducted among 20 HF patients and an age- and education-matched comparison group of 20 healthy adults to test the efficacy of the NRE intervention compared with an active control intervention...

OBJECTIVE: The global burden of disease attributable to high blood pressure showed that 54% of stroke and 47% of ishaemic heart disease worldwide were due to hypertension. Hypertension is still the main risk factor for premature death worldwide and, in particular, in low- and middle-income countries. We aimed to assess prehypertension and hypertension prevalence among a predominantly Asian and African population living in urban Suriname, a middle-income country in South America. DESIGN AND METHOD: We used data from the Healthy Life in Suriname study, in which 1,152 men and women aged 18-70 y living in the capital were randomly selected...

Big data indicates the large and ever-increasing volumes of data adhere to the following 4Vs: volume (ever-increasing amount), velocity (quickly generated), variety (many different types), veracity (from trustable sources). The last decade has seen huge advances in the amount of data we routinely generate and collect in pretty much everything we do, as well as our ability to use technology to analyze and understand it. The routine operation of modern health care systems also produces an abundance of electronically stored data on an ongoing basis as a byproduct of clinical practice...

OBJECTIVE: The role of the renin angiotensin aldosterone system (RAAS) and the gene variants of its components in hypertension have been investigated in various studies. A local tissue-specific renin-angiotensin system (local RAS) has considered as a regulator of cardiovascular physiology and homeostasis. However, no report has described the vagina protective efficacy of RAS inhibitors including ARB and ACEI. Therefore, we aim to investigate the effect of ARBs and ACEI on the vagina and cardiac expression of the local renin-angiotensin components...

There is accumulating evidence that RAS inhibitors not only reduce blood pressure, but also exert pleiotropic effects, including a renoprotective effect, amelioration of insulin resistance, reduction in onset of diabetes, and suppression of cardiovascular remodelling,. However, the definite benefit of RAS inhibition in treatment of hypertension with CKD or DM is not conclusive. We previously performed the OlmeSartan and Calcium Antagonists Randomized (OSCAR) study comparing the preventive effect of high-dose ARB therapy versus ARB plus CCB combination therapy on cardiovascular morbidity and mortality in 1164 Japanese elderly hypertensive patients with baseline type 2 diabetes and/or CVD (Am J Med (2012))...
