Doppler echocardiography can provide reliable and repeatable measures of cardiac index (CI), whereas lung ultrasound (LUS) represents a quantitative approach to assess pulmonary congestion. We tested the hypothesis that simultaneous assessment of CI and LUS during exercise stress echocardiography (ESE) may define heart failure (HF) outpatients with different risk of adverse outcome. Standard transthoracic echocardiography and LUS (B-lines) evaluation were assessed during semisupine ESE. CI and B-lines were measured at baseline and peak exercise...

Discrimination has is an important social determinant of health and though some research has been carried out on this it is mostly from the United States, which may not be generalisable to Europe and Sweden. This study investigated the association between self-reported experiences of repeated discrimination and all-cause mortality in Scania, Sweden. The Scania Public Health survey was sent out in 2008 with a follow-up in 2013 through the Swedish national cause of death register (N=28,062). The exposure variable under investigation was self-reported discrimination and the outcome variable was all-cause mortality...

Lifestyle interventions, including exercise and dietary supplementation, can modify DNA methylation and exert health benefits; however, the underlying mechanisms are poorly understood. Here we investigated the impact of acute aerobic exercise and the supplementation of omega-3 polyunsaturated fatty acids (n-3 PUFA) and extra virgin olive oil (EVOO) on global and gene-specific (PPARGC1A, IL6 and TNF) DNA methylation, and DNMT mRNA expression in leukocytes of disease-free individuals. Eight trained male cyclists completed an exercise test before and after a four-week supplementation of n-3 PUFA and EVOO in a double-blind, randomised, repeated measures design...

BACKGROUND: Catecholamingergic polymorphic ventricular tachycardia (CPVT) is characterized by adrenergically-induced VT, syncope, and sudden cardiac arrest (SCA). In the absence of structural disease, exercise-provoked premature ventricular contractions in bigeminy/couplets and non-sustained VT are highly predictive of CPVT. OBJECTIVE: To determine the number of missed/delayed CPVT diagnoses attributable to exercise testing oversights in a cohort of young SCA survivors...

BACKGROUND: Although suggested by practice guidelines, the need for pre-exercise stress testing in asymptomatic people with diabetes remains controversial. We examined the utility of screening with pre-exercise stress testing in patients with diabetes. METHODS: We completed a cohort study, evaluating patients with diabetes who attended an exercise program intake session between 2007 and 2012. The exposure of interest was referral for pre-exercise stress testing determined by an algorithm requiring sedentary patients with diabetes and ≥ 1 cardiac risk factor to undergo testing...

AIMS: We sought to estimate patients' age based on their stress testing exercise performance (A-BEST), and evaluate whether A-BEST would be a better predictor of mortality when compared to chronological age. METHODS: We included 126,356 consecutive patients referred for exercise (electrocardiography, echocardiography or myocardial perfusion imaging) stress testing at our institution from January 1st, 1991 to February 27th, 2015. Estimated age was computed based on exercise capacity (number of peak estimated metabolic equivalents of task), chronotropic reserve index and heart rate recovery, taking into account patient's gender and medications that affect heart rate...

BACKGROUND: Although the enhancement of early-diastolic intra-left ventricular pressure difference (IVPD) during exercise is considered to maintain exercise capacity, little is known about their relationship in heart failure (HF). METHODS AND RESULTS: Cardiopulmonary exercise testing and exercise-stress echocardiography were performed in 50 HF patients (left ventricular (LV) ejection fraction 39±15%). Echocardiographic images were obtained at rest, submaximal, and peak exercise...

INTRODUCTION: Objective Structured Clinical Examinations (OSCEs) are an established method of assessment for dental undergraduates. There is little published dental education research exploring the views of undergraduates towards OSCEs. AIM: To explore and describe the views of dental undergraduates towards OSCEs. METHOD: A sequential mixed methods design was applied. This included a cross-sectional survey of all 204 dental undergraduates in Years 2, 3 and 4 within a UK dental school using an anonymous self-report online questionnaire (response rate 57%), which was followed by two focus group interviews of n=10 Year-2 students...

Mitral valve prolapse is generally a benign condition characterized by fibromyxomatous changes of the mitral leaflet with displacement into the left atrium and late-systolic regurgitation. Although it is an old clinical entity, it still arouses perplexity in diagnosis and clinical management. Complications, such as mitral regurgitation (MR), atrial fibrillation, congestive heart failure, endocarditis, ventricular arrhythmias, and sudden cardiac death (SCD), have been reported. A large proportion of the overall causes of SCD in young competitive athletes is explained by mitral valve prolapse...

BACKGROUND AND OBJECTIVES: Efficacious interventions soon after trauma exposure to prevent posttraumatic stress disorder (PTSD) are scarce. Evidence suggests that post-trauma, reminder cues to reactivate trauma memory followed by a cognitive visuospatial task, such as Tetris, reduce later intrusive images. Furthermore, studies indicate that aerobic exercise may reduce PTSD symptoms. The present study aimed to test whether playing Tetris, without prior reminder cues, after an experimental trauma limits the development of analogue symptoms and to compare Tetris to aerobic exercise, which could plausibly alter cognitive-affective processing of the trauma as well...

Objective: A constricted, upper chest breathing pattern and postural dealignments habitually accompany exercise-induced laryngeal obstruction (EILO), but there are few effective treatments for athletes presenting with EILO. This case series was conducted to examine whether physiotherapy based on principles from the Norwegian psychomotor physiotherapy (NPMP) combined with elements of cognitive behavioural therapy can reduce laryngeal distress in athletes with EILO. Methods: Respiratory distress in four subjects was examined by interview prior to a physiotherapeutic body examination...

The chemical and functional interactions between Reactive Oxygen (ROS), Nitrogen (RNS) and Sulfur (RSS) species allow organisms to detect and respond to metabolic and environmental stressors, such as exercise and altitude exposure. Whether redox markers and constituents of this 'Reactive Species Interactome' (RSI) differ in concentration between arterial and venous blood is unknown. We hypothesised that such measurements may provide useful insight into metabolic/redox regulation at the whole-body level and would be consistent between individuals exposed to identical challenges...

BACKGROUND: The most common implant options for the metacarpophalangeal joint arthroplasty include silicone, pyrocarbon and metal-polyethylene. A systematic review of outcomes of silicone and pyrocarbon implants was conducted; however, a similar exercise for metal-polyethylene implants revealed a scarcity of published results and lack of long-term follow-up studies. The aim of the present work is to test the hypothesis that the magnitude of metacarpophalangeal joint cyclic loads generates stress and strain behaviour, which leads to long-term reduced risk of metal-polyethylene component loosening...

About one-third of adults are physically inactive and thus prone to cardiovascular diseases. While self-efficacy mediates health behavior, its influences on exercise behavior among Chinese is yet to be explored by a validated instrument. This study aimed to examine the psychometric properties of the Hong Kong Chinese version of the Cardiac Exercise Self-efficacy Instrument (CESEI-C), which had been translated previously by these authors. The psychometric properties of the CESEI-C were tested with 160 Hong Kong Chinese with cardiovascular risk...
