Exercise training reduces the side effects of cancer treatments, however, the stress hormone response to acute exercise during prostate cancer (PCa) treatment is unclear. PURPOSE: To examine the effects of acute exercise on circulating cortisol, epinephrine (Epi), and norepinephrine (NE) concentrations during PCa treatment with and without androgen deprivation therapy (ADT). METHODS: Men with PCa (n=11), with PCa on ADT (n=11) and non-cancer controls (n=8) had blood samples for stress hormones collected before and immediately (0h), 2h, and 24h after 45 minutes of intermittent cycling at 60% of peak wattage...

A 15-year-old girl of Asian origin, hailing from a rural agrarian background, presented with history of multiple episodes of dizziness for 3 years. The episodes were precipitated mostly by emotional and/or physical stress and relieved on lying down, with a few episodes culminating in transient loss of consciousness. As preliminary cardiac and neurological evaluation were normal, she was being treated by the primary physician as a case of probable psychogenic syncope, supported by the consistent association of the episodes with emotional stress...

BACKGROUND: Exercise capacity is associated with survival in the general population. Whether this applies to patients with treated depression is not clear. HYPOTHESIS: High exercise capacity remains associated with lower risk of all-cause mortality (ACM) and nonfatal myocardial infraction (MI) among patients with treated depression. METHODS: We included 5128 patients on antidepressant medications who completed a clinically indicated exercise stress test between 1991 and 2009...

Mitochondria intricately modulate their energy production through the control of mitochondrial adaptation (mitochondrial biogenesis, fusion, and/or fission) to meet energy demands. Nutrient overload may result in dysregulated mitochondrial biogenesis, morphology toward mitochondrial fragmentation, and oxidative stress in the skeletal muscle. In addition, physical activity and diet components influence mitochondrial function. Exercise may stimulate mitochondrial biogenesis and promote mitochondrial fusion/fission in the skeletal muscle...

Background In developing countries like Pakistan, treatment is mediated by private and public healthcare setups with a limited budget for health facilities. Moreover, the inappropriate use of treadmill tests imposes a burden on healthcare resources and leads to unwarranted interventions. Our aim is to assess the prevalence and predictors of inappropriate referrals for the exercise tolerance test (ETT) to diagnose coronary artery disease (CAD) while taking public and private healthcare settings into consideration...

Introduction: The antioxidant and anti-inflammatory effects of Tai chi (TC) exercise training in healthy older adults has been demonstrated. However, there are no studies on this effect in older adults with metabolic syndrome (MetS). Purpose: The aim of this study was to determine the effect of TC exercise on oxidative stress and inflammatory markers in older adults with MetS. Methods: A quasi-experimental study was carried out with a sample of 110 older sedentary volunteers with clinical diagnoses of MetS: (i) a control group, n = 50, of individuals who do not participate in physical exercise, of which 37 fulfilled the entire study protocol, and (ii) an experimental group, n = 60, of subjects enrolled in a TC exercise training program (eight-form easy), 5 days a week for 6 months, in sessions of 50 min, under the supervision of a qualified instructor, of which 48 fulfilled the entire study protocol...

Background: Vascular aging is known to induce progressive stiffening of the large elastic arteries, altering vascular hemodynamics under both rest and stress conditions. In this study, we aimed to investigate changes in vascular hemodynamics in response to isometric handgrip exercise across ages. Participants and methods: We included 62 participants, who were divided into three age categories: 20-40 (n=22), 41-60 (n=20), and 61-80 (n=20) years. Vascular hemodynamics were measured using the Mobil-o-Graph® based on the pulsatile pressure changes in the brachial artery...

BACKGROUND: Current diagnosis of heart failure with preserved ejection fraction (HFpEF) is suboptimal. We tested the hypothesis that comprehensive machine learning (ML) of left ventricular function at rest and exercise objectively captures differences between HFpEF and healthy subjects. METHODS AND RESULTS: One hundred fifty-six subjects aged >60 years (72 HFpEF+33 healthy for the initial analyses; 24 hypertensive+27 breathless for independent evaluation) underwent stress echocardiography, in the MEDIA study (Metabolic Road to Diastolic Heart Failure)...

Natural Killer cells are cytotoxic lymphocytes that recognize and eliminate tumor cells. Exercise enhances NK cell cytotoxic activity (NKCA), yet the underlying mechanisms are not fully understood. Exercise-induced shifts in NK-cell subsets has been proposed as one mechanism. Alternatively, exercise alters stress hormone and cytokine levels, which are also known to affect NKCA. AIM: Determine the role(s) of exercise-induced shifts in the proportions of NK-cell subsets found in the blood, and changes in serum IL-2, IL-6, IL-12, IFN-γ, TNF-α and cortisol, on exercise-induced changes in NKCA...

Chest pain is the second most common presenting symptom to emergency departments (ED) in Australia, although up to 85% of these patients do not have an acute coronary syndrome (ACS). Cardiologist-led rapid access chest pain clinics (RACPC) have been proposed overseas to assist in the management of such patients, with prompt outpatient assessment if patients are deemed low risk and discharged from the ED. The use of RACPCs in Australia has been only recently proposed; we therefore sought to examine one such RACPC in an Australian context...

Alcohol-induced oxidative stress is involved in the development and progression of various pathological conditions and diseases. On the other hand, exercise training has been shown to improve redox status, thus attenuating oxidative stress-associated disease processes. The purpose of the present study was to evaluate the effect of an exercise training program that has been previously reported to decrease alcohol consumption on blood redox status in heavy drinkers. In a non-randomized within-subject design, 11 sedentary, heavily drinking men (age: 30...

AIMS: Obesity is associated with lipid aggregation in adipocytes and macrophage infiltration, leading to increased oxidative stress and inflammation. Increased cell-free DNA (cfDNA) concentrations have been observed in clinical conditions of systemic inflammation. While the beneficial effects of regular physical activity on the release of circulating cfDNA still remain unknown, acute intense exercise has been shown to increase inflammatory cytokines and cfDNA concentrations in normal-weight individuals...

This review summarizes the opening keynote presentation overview of the American Physiological Society conference on Cardiovascular Aging: New Frontiers and Old Friends held in Westminster, CO, in August 2017. Age is the primary risk factor for cardiovascular diseases (CVD). Without effective intervention, increased numbers of older adults in the future will translate to greater prevalence of CVD and related disorders. Advancing age increases the risk of CVD partly via direct effects on the heart and through increases in blood pressure; however, much of the risk is mediated by arterial dysfunction, including large elastic artery stiffening and both macro- and micro-vascular endothelial dysfunction...

The calibrated application of limited duration, cyclic, moderately intense hypoxia-reoxygenation increases cardiac resistance to ischemia-reperfusion stress. These intermittent hypoxic conditioning (IHC) programs consistently produce striking reductions in myocardial infarction and ventricular tachyarrhythmias following coronary artery occlusion and reperfusion, and in many cases, improved contractile function and coronary blood flow. These IHC protocols are fundamentally different from those used to simulate sleep apnea, a recognized cardiovascular risk factor...

BACKGROUND: Hypertension (HTN) is the main cause of cardiovascular diseases accounting for one third of global mortality. Physical exercise reduces the incidence and prevalence of HTN and cardiovascular morbidity and mortality. Exercises recommended for hypertensive patients include supervised cardiac rehabilitation, which occurs in rehabilitation centers, and partly supervised rehabilitation, with individual prescription of exercises conducted at patients' residences. OBJECTIVE: Compare clinical and functional parameters of hypertensive patients subjected to two cardiac rehabilitation protocols: supervised and partly supervised...

The impact of health, management, and microbiota on olfactory function in canines has not been examined in review. The most important characteristic of the detection canine is its sense of smell. Olfactory receptors are primarily located on the ethmoturbinates of the nasal cavity. The vomeronasal organ is an additional site of odor detection that detects chemical signals that stimulate behavioral and/or physiological changes. Recent advances in the genetics of olfaction suggest that genetic changes, along with the unique anatomy and airflow of the canine nose, are responsible for the macrosmia of the species...
