Immersion pulmonary oedema (IPE) is particularly associated with an excessive reaction to exercise and/or cold stress. IPE usually resolves without recompression therapy within a day or two. Herein we report a diver diagnosed with IPE, in whom symptoms persisted for five days. A 58-year-old man presented with sudden onset of dyspnoea, cough and haemoptysis after surfacing. He was an experienced diving instructor with a history of moderate mitral valve regurgitation. While IPE was diagnosed and oxygen administered, respiratory symptoms deteriorated, and serum C-reactive protein elevated...

The imbalance between the reactive oxygen (ROS) and nitrogen (RNS) species production and their handling by the antioxidant machinery (low molecular weight antioxidant molecules and antioxidant enzymes), also known as oxidative stress, is a condition caused by physiological and pathological processes. Moreover, oxidative stress may be due to an overproduction of free radicals during physical exercise. Excess of radical species leads to the modification of molecules, such as proteins - the most susceptible to oxidative modification - lipids and DNA...

BACKGROUND: Previous studies have revealed that triglyceride to high-density lipoprotein cholesterol (HDL-C) ratio (henceforth TG/HDL-C) is one of the major risk factors for cardiovascular disease, insulin resistance and metabolism syndrome. However, there are fewer investigations of the correlations between the aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio and brachial ankle pulse wave velocity (baPWV). This study was undertaken to investigate the relationship between the AST to ALT ratio and brachial-ankle pulse wave velocity (baPWV) in a Japanese population...

Background: Compulsive exercise has been recognized as a highly prevalent symptom in eating disorders (ED) for over 100 years and is associated with poor short-term and long-term treatment outcome. Progress in understanding and treatment of compulsive exercise will remain limited as long as no consensus framework for definition and assessment of compulsive exercise exists, as results cannot be compared across clinical studies.Based on existing literature, it was our aim to propose a transdiagnostic definition and a clinical assessment for compulsive exercise, that can be applied to adolescent and adult patients with ED...

Polycystic ovary syndrome (PCOS) presents with a spectrum of conditions resulting from androgen excess, anovulation and metabolic syndrome. Patients with PCOS may see their primary care physicians for various presentations, including hirsutism, acne, menstrual irregularities, infertility, obesity, and psychiatric disorders such as anxiety and depression. Management of these patients should include screening for Type 2 diabetes mellitus, dyslipidaemia and hypertension. Treatment should be targeted to each patient's phenotype and personal expectations such as desire for pregnancy...

BACKGROUND: Excess postexercise oxygen consumption (EPOC) is an elevation in oxygen consumption (Vo₂) following exercise. Altitude decreases maximal oxygen uptake; however, studies are equivocal concerning the effect on resting metabolic rate. The EPOC response has not been studied with normobaric hypoxia. The purpose was to observe EPOC following constant-load cycling in normobaric hypoxia. METHODS: Subjects ( N = 7 women, 7 men) completed resting metabolic rate testing between 06:00 and 08:30. Constant workload cycle exercise was performed (10 min at 100 W) while breathing air from an altitude simulator under the following conditions: normoxic control (CON), 3353 m (11,001 ft; HI), and 6401 m (21,001 ft; EXT)...

Neuromuscular activity, organized in coordinated patterns, forms the basis of task-specific function in sports and exercise. The content and extent of these patterns may be variable, but include elements of activation/inhibition, co-activation, concentric/eccentric activation, proximal-to-distal activation, plyometric activation, and preactivation stiffness. They may be based on inherent neuromuscular architecture, but are commonly affected by positive or negative adaptations to imposed functional demands. Positive neuromuscular adaptations improve the efficiency of performing the task, which can result in less energy expenditure, maximum force delivered to the task, and protection of involved joints from excessive loads/motions, and improve the effectiveness of task performance...

OBJECTIVES:  Disease progression in metastatic castration-resistant prostate cancer (mCRPC) is dependent on androgen signaling. This case describes the complex adaptive androgen signaling mechanisms in mCRPC and illustrates that caution should be exercised when treating these patients with drugs influencing the androgen axis. METHODS:  Single case report and review of the literature. RESULTS:  We report the case of an 86-year-old man with mCRPC, treated with the secondary antihormonal agent abiraterone acetate...

High radiant heat load reduces endurance exercise performance in the heat indoors, but this remains unconfirmed in outdoor exercise. The current study investigated the effects of variations in solar radiation on self-regulated exercise intensity and thermoregulatory responses in the heat outdoors at a fixed rating of perceived exertion (RPE). Ten male participants completed 45-min cycling exercise in hot outdoor environments (about 31 °C) at a freely chosen resistance and cadence at an RPE of 13 (somewhat hard)...

BACKGROUND: Public health campaigns commonly emphasise the association between excess weight and poor health. The present study aimed to examine the effect of information about weight and engagement with health behaviours on judgements of a person's health. METHOD: In two experimental studies, participants were asked to evaluate a target person's health and to make recommendations about that person's health-related behaviours. In Study 1 (n = 306), we manipulated the target's behaviours (healthy, unhealthy) and body weight (normal, overweight, obese); in Study 2 (n = 192), we manipulated the behaviour of an overweight target (healthy, unhealthy)...

Muscle dysmorphia (MD) is a condition that is characterized by body image disturbance, a drive for muscularity and excessive exercising. It leads to considerable functional impairment. Most previous studies focused on male samples. The study aimed to validate a German version of the Muscle Dysmorphic Disorder Inventory (MDDI) in order to make the instrument available in German speaking countries. We further aimed to explore for gender differences in the MDDI factors (measurement invariance) and to assess the relationship between MD and positive dimensions of body experience as well as exercise dependence...

Rehabilitation (Rehab) exercise can benefit cardiac patients as it can promote the recovery and improve the heart wellness. However, heart failure (HF) patients can only take mild exercise, since excessive exercise may lead to fatal events. It is important to control the exercise intensity at a desired level to maximize exercise benefit. Heart Rate (HR) is an essential factor for measuring exercise intensity. Mathematical models of HR can be used to study exercise physiology. However, HR models involve model uncertainty, resulting from model calibration or variability in patients...

Obesity is a chronic multifactorial disease, characterized by an excessive accumulation of adipose tissue. It is usually the result of excessive food intake and/or low energy expenditure. Obesity can be triggered by lifestyle, nutritional, genetic, environmental, hormonal and psychological factors. Several strategies are used to treat obesity, including dietary reeducation, with balanced food intake, increased physical exercise, in order to promote energy expenditure and to overcome the insufficiency in weight reduction by other strategies, and the administration of drugs to treat obesity...
