Previous work suggests that women may exhibit a greater respiratory limitation to exercise compared to height-matched men. Diffusion capacity (DLCO) increases with incremental exercise, and the smaller lungs of women may limit membrane diffusing capacity (Dm) and pulmonary capillary blood volume (Vc) in response to the increased oxygen demand. We hypothesized that females would have a lower DLCO, DLCO relative to cardiac output (DLCO/Q), Dm, Vc, and pulmonary transit time, secondary to lower Vc at peak exercise...

Exercise is increasingly being used as a treatment for alcohol use disorders (AUD), but the interactive effects of alcohol and exercise on the brain remain largely unexplored. Alcohol damages the brain, in part by altering glial functioning. In contrast, exercise promotes glial health and plasticity. In the present study, we investigated whether binge alcohol would attenuate the effects of subsequent exercise on glia. We focused on the medial prefrontal cortex (mPFC), an alcohol-vulnerable region that also undergoes neuroplastic changes in response to exercise...

BACKGROUND AND AIM: Research shows that regular engagement in physical activity in childhood is associated with multiple physical and psychosocial health benefits. The data on associations between children physical activity level and built environment in Lithuania are limited. The built environment is one of many variables thought to affect children physical activity level. But consequently there is growing interest in how physical environment influences physical activity of school age children...

BACKGROUND: We aimed to determine the frequency and predictors of exercise limitation after pulmonary embolism (PE), and to assess its association with health-related quality of life (HRQOL) and dyspnea. METHODS: 100 patients with acute PE were recruited at five Canadian hospitals from 2010-2013. Cardiopulmonary exercise testing (CPET) was performed at 1 and 12 months. Quality of life, dyspnea, six-minute walk distance (6MWD), residual clot burden (perfusion (Q) scan; CT pulmonary angiography (CTPA)), cardiac function (echocardiogram) and pulmonary function tests (PFT) were measured during follow-up...

Obesity may associate with greater cardiovascular risk in adults with congenital heart disease (ACHD) than in the general population. As ACHD often have exercise limitations, they may be uniquely predisposed to obesity. Nevertheless, obesity prevalence in ACHD, compared with the general population, has not been quantified in a large US cohort. Hence, we sought to determine the prevalence of obesity (30 ≤ body mass index <40) and morbid obesity (body mass index ≥40), in a large cohort of ACHD, compared with matched controls...

A 23-day-old infant referred to the neonatal intensive care unit with difficulty breathing and inspiratory stridor increasing with exercise. Medical history included a cardiothoracic surgery for transposition of the great arteries, patent ductus arteriosus, atrial septal defect, and a history of intensive care unit from surgery. Flexible fiberoptic transnasal laryngoscopy revealed subglottic stenosis that was probably caused by prolonged intubation with a higher airway pressure. Computed tomographic scan of the neck showed a tiny stenosis without cartilage deformity and limited in subglottic region...

The aim of this study was to evaluate the reproducibility and validity of the "Footeval" test, which evaluates football players' aerobic level in conditions close to those of football practice (intermittent, including technical skills). Twenty-four highly trained subjects from an elite football academy (17.8 ± 1.4 years, 5 training sessions per week) performed two Footeval sessions in a period of 7 days. Physiological variables measured during these sessions (VO2max 58.1 ± 5.6 and 58.7 ± 6.2 ml·min(-1)·kg(-1); RER 1...

STUDY QUESTION: What is the impact of law and policy upon the experience of embryo donation for reproductive use? SUMMARY ANSWER: Access to, and experience of, embryo donation are influenced by a number of external factors including laws that impose embryo storage limits, those that frame counselling and approval requirements and allow for, or mandate, donor identity disclosure. WHAT IS KNOWN ALREADY: To date only three qualitative studies in Australia and New Zealand have been completed on the experience of embryo donation for reproductive purposes, each with a small cohort of interviewees and divergent findings...

Hypertensive pregnancy (HTNP) is a risk factor for future cardiovascular disease. Exaggerated cardiovascular responses to physical stress are also considered an independent marker of cardiovascular disease risk. However, there are limited data regarding the blood pressure (BP) responses to acute stress in women, who have a history of HTNP. Hence, the aim of the study is to compare BP responses to a physical stress in postmenopausal women with a history of HTNP to age- and parity-matched women with a history of normotensive pregnancy (NP)...

PURPOSE: There is limited research on the role of enjoyment of exercise among people with arthritis. The aim of the present study was to determine distinct viewpoints on exercise held by people with arthritis, and how enjoyment features in these viewpoints. METHODS: A Q-methodology study was conducted, which involved two interviews with people with rheumatoid arthritis, osteoarthritis or ankylosing spondylitis (aged 20-85 years). In the first interviews, 11 participants helped to create the Q-set, a set of statements reflecting a range of existing views on exercising...

Cancer and cardiovascular disease are major causes of morbidity and mortality worldwide. Older cancer patients often wrestle with underlying heart disease during cancer therapy while childhood cancer survivors are living long enough to face long-term unintended cardiac consequences of cancer therapies, including anthracyclines. Although effective and widely used, particularly in the pediatric population, side effects including dose-dependent association with cardiac dysfunction limits its usage. Unfortunately, there is only one US FDA-approved drug (dexrazoxane) available for the prevention and mitigation of cardiotoxicity related to anthracycline therapy...

As the role of the clinical pharmacist continues to develop and advance, it is critical to ensure pharmacists can operate in a practice environment and workflow that supports the full deployment of their clinical skills. When pharmacy technician roles are optimized, patient safety can be enhanced and pharmacists may dedicate more time to advanced clinical services. Currently, 17 states allow technicians to accept verbal prescriptions called in by a prescriber or prescriber's agent, or transfer a prescription order from one pharmacy to another...

We tested the hypothesis that critical intensity in cycling can be determined from a single delta blood lactate in the third minute of a submaximal cycle ergometer trial. Fourteen healthy young men performed four to six constant-power-output trials on a cycle ergometer to the limit of tolerance. Critical intensity was calculated via a linear model and subsequently validated. Lactate was measured at baseline and at 3 min from exercise onset. Delta lactate was the difference between these measures. Based on individual trials, we obtained the delta lactate-% validated critical intensity relationship and thereafter an estimate of critical intensity was computed...

Sport injury rehabilitation has moved from predominately physical treatment to a more holistic care. However, limited research has explored the views and experiences of those involved in such an approach. The purpose of this study was to preliminarily investigate sport psychology consultants' (SPCs') views and experiences of an interprofessional team approach to sport injury rehabilitation. A cross-sectional online survey previously used with athletic trainers was distributed via a US-based sport/exercise psychology list-serve (N = 1245)...

Internationally, mental illness is high in prison populations. Collaboration between the correctional services (CS) and mental health services (MHS) is required to address this. Little is known of the collaborative processes in this context, however. This article presents the findings of a study exploring the characteristics of collaborative practices between the MHS and CS in a Norwegian context. A purposeful sample (n = 12) of MHS and CS leaders was recruited from one region in Norway. Taking a generic qualitative approach, semi-structured interviews with each participant explored specific structures that promoted collaboration, the nature of collaborative relationships, and factors that facilitated or constrained these...

BACKGROUND: Type 2 diabetes mellitus is associated with abnormal markers of inflammatory cytokines and oxidative stress markers. Although, these abnormalities could be modulated with weight reduction; there is limitation in clinical studies that have addressed the beneficial effects of weight reduction in modulating biomarkers of inflammatory cytokines and oxidative stress for obesity associated with type 2 diabetes mellitus. OBJECTIVE: This study was designed to detect the effects of weight loss on the inflammatory cytokines, oxidative stress markers in obese type 2 diabetic patients...
