INTRODUCTION: Non-communicable diseases (NCD) now represent the major burden of adverse health in most countries. It is clear that much of the risk of such conditions begins very early in life, potentially in utero. Given their complex aetiology, an understanding of the origins of NCD requires an in-depth analysis of the interplay between genetic variation and environment, preferably over time. For decades, twin studies have played a key role in understanding such traits. Their strength lies in the ability to disentangle genetic and environmental factors that contribute to a phenotype...

Introduction and purpose: Chronic pancreatitis (CP) involves progressive inflammatory changes to the pancreas and can lead to permanent structural damage and impairment of both endocrine and exocrine functions. Current reports highlight a rise in the incidence and prevalence of CP. However, there is limited data currently available concerning patients with CP undergoing exercise therapy (ET). We aim to prospectively examine the influence of ET on sarcopenia in patients with CP. Methods and analysis: A detailed evaluation of the nutritional condition and the daily physical activities of each participant will be conducted prior to entering the study...

INTRODUCTION: Hardware removal in healed trochanteric fractures (TF) in the absence of infection or significant mechanical complications is rarely indicated. However, in patients with persistent pain, prominent material and discomfort in the activities of daily living, the implant is eventually removed. Publications of ipsilateral femoral neck fracture after removal of implants from healed trochanteric fractures (FNFARIHTF) just because of pain or discomfort are rare. The purpose of this systematic review of the literature is to report on the eventual risk factors, the mechanisms, the clinical presentation, and frequency, and to pay special emphasis in their prevention...

Our study in the Journal of Sports Sciences was originally designed to test whether the bar-velocity is a precise indicator of the power training intensity (i.e., optimum loads) in different exercises commonly included in athletes' training programs. Furthermore, we presented secondary findings, related to the actual results obtained in our assessments. As a cross-sectional study with clear objectives, we focused on discussing issues and applications pertaining to neuromuscular training interventions, such as: (1) describing the advantages of using bar-velocities to control the power training intensity, (2) defining a range of loads capable of maximizing the power production in certain ballistic and traditional exercises, and (3) revealing the differences between these exercises and the respective implications for training...

INTRODUCTION: Early pulmonary rehabilitation is recommended after a severe exacerbation of chronic obstructive pulmonary disease (COPD). However, this is difficult to implement, particularly for exercise training. High-flow nasal therapy (HFNT) may reduce the work of breathing and dyspnoea and may improve exercise tolerance. METHODS AND ANALYSIS: This is a single-centre, prospective, controlled, randomised, cross-over study. Eligible patients will have a diagnosis of COPD (postbronchodilator forced expiratory volume in 1 s/forced vital capacity ratio of <0...

Research on childhood epilepsy has predominantly used quantitative methodologies to examine the impact of epilepsy on young people and their families. These studies generally give a negative picture of the condition, which is at odds with a strengths-based social work perspective, and provide little understanding of young people's experiences of living with epilepsy. A systematic review of qualitative studies that explored young people's perspectives was conducted. Inclusion criteria were as follows: young people ages 13 to 18 years diagnosed with epilepsy, qualitative data collection methods, studies published in English-language peer-reviewed journals, and gray literature...

INTRODUCTION: Physical activity is a cornerstone in type 2 diabetes (T2D) rehabilitation. Effective long-term and low-cost strategies to keep these patients' physically active are needed. However, maintaining physical activity behaviour is difficult once formalised interventions end. Structured exercise training supported by mobile technology and remote feedback is potentially an effective strategy. The objective of the trial is to investigate whether mobile health support using the InterWalk application for smartphones is effective in increasing physical activity levels in persons with T2D over time compared with standard care...

BACKGROUND: Rates of mental health disorders are significantly greater in children with physical illnesses than in physically well children. Children with neurological conditions, such as epilepsy, are known to have particularly high rates of mental health disorders. Despite this, mental health problems in children with neurological conditions have remained under-recognised and under-treated in clinical settings. Evidence-based guided self-help interventions are efficacious in reducing symptoms of mental health disorders in children, but their efficacy in reducing symptoms of common mental health disorders in children with neurological conditions has not been investigated...

Chronic laryngeal symptoms are often attributed to gastroesophageal reflux disease based on nonspecific testing by laryngoscopy resulting in overdiagnosis of this condition. Identifying optimal means by which we can diagnose reflux in patients with chronic laryngeal symptoms is an unmet clinical area. One such technique might be measurement of oropharyngeal acid exposure employing a novel pH monitoring device. We outline the strengths and limitations of this new technology relative to the observational cohort study by Yadlapti et al...

A standardized fitness assessment is critical for the development of an individualized exercise prescription. Although the benefits of aquatic exercise have been well established, there remains the need for a standardized non-swimming protocol to accurately assess cardiorespiratory fitness (CRF) in shallow water. The present investigation was designed to assess: 1) reliability of a standardized Shallow Water Run (SWR) test of CRF; and 2) accuracy of a standardized SWR compared with a land-based treadmill test (LTM)...

BACKGROUND: Cystic fibrosis is a genetically inherited, life-threatening condition that affects major organs. The management of cystic fibrosis involves a multi-faceted daily treatment regimen that includes airway clearance techniques, pancreatic enzymes and other medications. Previous studies have found that compliance with this intensive treatment is poor, especially among adolescents. Because of both the nature and consequences of the illness and the relentless demands of the treatment, many individuals with cystic fibrosis have a poor quality of life...
