Heart failure (HF) is a major cause of death and hospitalization worldwide. Despite advances in reducing mortality, prognosis remains poor and prevalence has reached epidemic proportions. The limitations of available preclinical models represent a major hurdle in the development of new therapies. Myocardial infarction (MI) is a main cause of HF in humans, and mouse models of MI are often used to study HF mechanisms and experimental treatments. We investigated whether MI in mice constitutes an appropriate model of HF...

Current methods to quantify RNA dynamics are beset with limitations. Here, we developed a novel stable isotope (D2O)-methodology to quantify RNA synthesis (i.e. ribosomal biogenesis) in cells, animal models, and humans. Firstly, proliferating C2C12 cells were incubated in D2O-enriched media and myotubes (±) 50ng.ml(-1) IGF-1. Secondly, rat quadriceps [untrained n=9; 7-wks interval-"like" training n=13] were collected after ~3-wks D2O (70-Atom%) administration, with body-water enrichment (BWE) monitored via blood sampling...

OBJECTIVES: Posterior cruciate ligament (PCL) injuries are relatively common injuries associated with athletic activities and high-energy trauma. Posterolateral corner (PLC) injuries frequently accompany injury to the PCL. Diagnosis can be challenging and requires a comprehensive history and physical examination. Patients frequently report vague, nonspecific symptoms and the mechanism of injury is often useful in localizing injured structures. Two of the more common mechanisms for PCL injury include a direct blow to the proximal anterior tibia with the knee flexed, as well as a significant knee hyperextension injury...

INTRODUCTION: One of the most common reasons individuals do not seek mental health treatment is a preference to manage emotional concerns on their own. Self-management refers to the strategies that individuals use on their own (i.e., without professional guidance) to manage symptoms. Little research has examined self-management for anxiety despite its potential utility as the first step in a stepped care approach to primary care. The objectives of this study were to describe patients' anxiety self-management strategies, identify which types were perceived to be effective, and explore potential correlates...

We report a case of spontaneous pneumomediastinum with unusual clinical presentation. The most common symptoms of spontaneous mediastinum are chest pain and shortness of breath. Our patient presented with neck swelling and change in voice, an unusual presentation for spontaneous pneumothorax. A 30-year-old previously healthy man presented with complaints of neck swelling and hoarseness of voice beginning after an intense coughing spell. He had no other complaints. He denied any trauma to the chest, nausea, vomiting, recent air travel, scuba diving or recreational drug use...

BACKGROUND: Although hypothyroidism has an insidious onset and relatively asymptomatic, exertional dyspnea and fatigue can be the presenting complaints. OBJECTIVES: The aim is to assess functional lung impairment in hypothyroid patients both at rest and during exercise. METHODS: A case-control study was carried out on 42 patients with newly diagnosed hypothyroidism and 12 control subjects. Hypothyroidism was diagnosed based on high value of thyroid stimulating hormone (TSH) ≥6 μIU/ml, and low value of free thyroxin (FT4) ≤0...

OBJECTIVE: Experimental animal models demonstrate that autonomic activity regulates systemic inflammation. By contrast, human studies are limited in number and exclusively use heart rate variability (HRV) as an index of cardiac autonomic regulation. HRV measures are primarily dependent on, and need to be corrected for, heart rate. Thus, independent autonomic measures are required to confirm HRV-based findings. Here, the authors sought to replicate the findings of preceding HRV-based studies by using HRV-independent, exercise-evoked sympathetic and parasympathetic measures of cardiac autonomic regulation to examine the relationship between autonomic function and systemic inflammation...

PURPOSE: Weather-related disasters have increased dramatically in recent years. In 2012, severe flooding as a result of Hurricane Sandy necessitated the mid-storm patient evacuation of New York University Langone Medical Center. The purpose of this study was to explore, from the nurses' perspective, what the challenges and resources were to carrying out their responsibilities, and what the implications are for nursing education and preparation for disaster. DESIGN: This mixed-methods study included qualitative interviews with a purposive sample of nurses and an online survey of nurses who participated in the evacuation...

BACKGROUND: Patients facing a high-stakes clinical decision are often confronted with an overwhelming array of options. High-quality decisions about treatment should reflect patients' preferences as well as their clinical characteristics. Preference-assessment instruments typically focus on pre-selected clinical outcomes and attributes chosen by the investigator. OBJECTIVE: We sought to develop a patient-centered approach to elicit and compare the treatment goals of patients with multiple sclerosis (MS) and healthcare providers (HCPs)...

Geraghty's recent editorial on the PACE trial for chronic fatigue syndrome has stimulated a lively discussion. Here, I consider whether the published claims are justified by the data. I also discuss wider issues concerning trial procedures, researcher allegiance and participant reporting bias. Cognitive behavioural therapy and graded exercise therapy had modest, time-limited effects on self-report measures, but little effect on more objective measures such as fitness and employment status. Given that the trial was non-blinded, and the favoured treatments were promoted to participants as 'highly effective', these effects may reflect participant response bias...

OBJECTIVE: This study describes results of iCPET from the past, which used submaximal stress and multisensor high-fidelity catheters to exclude heart disease in a unique population of young adults. BACKGROUND: There has been resurgence in comprehensive hemodynamic evaluation of complex cardiovascular patients. Although dynamic assessments during cardiac catheterization have become commonplace, there remains limited information regarding left and right heart hemodynamic changes during supine exercise in young adults...

Background  Lower extremity peripheral arterial disease (PAD) is a common medical condition causing substantial morbidity. Limited data exist on whether discrepancies in PAD prevalence exist between the lower extremities using resting ankle-brachial indices (ABIs) and postexercise pressures. Objective  We predicted the prevalence of PAD between the lower extremities. Methods and Results  Consecutive patients who had undergone a noninvasive arterial lower extremity study at Mayo Clinic, Rochester, MN, between January 1996 and December 2012 with suspected PAD were retrospectively reviewed...

AIM: The aim of this study was to evaluate the impact of patient background including exercise capacity on the relationship between the blood pressure (BP) response to exercise and prognosis in patients visiting a cardiovascular hospital. METHODS: A total of 2134 patients who were referred to our hospital underwent symptom-limited maximal cardiopulmonary exercise testing, and were followed through medical records and mail. The BP response to exercise was defined as the difference between peak and rest systolic BP...

Longitudinal strain (LS) has been shown to be predictive of outcome in hypertrophic cardiomyopathy (HC). Percent predicted peak oxygen uptake (ppVO2), among other cardiopulmonary exercise testing (CPX) metrics, is a strong predictor of prognosis in HC. However, there has been limited investigation into the combination of LS and CPX metrics. This study sought to determine how LS and parameters of exercise performance contribute to prognosis in HC. One hundred and thirty-one consecutive patients with HC who underwent CPX and stress echocardiography were included...

Although many neurologic conditions are common, cures are rare and conventional treatments are often limited. Many patients, therefore, turn to complementary and alternative medicine (CAM). The use of selected, evidence-based CAM therapies for the prevention and treatment of migraine, carpal tunnel syndrome, and dementia are presented. Evidence is growing many of modalities, including nutrition, exercise, mind-body medicine, supplements, and acupuncture.

OBJECTIVES: Assisted suicide in Switzerland is mainly performed by right-to-die societies. Medical involvement is limited to the prescription of the drug and certification of eligibility. Palliative care has traditionally been perceived as generally opposed to assisted suicide, but little is known about palliative care physicians' involvement in assisted suicide practices. This paper aims to describe their perspectives and involvement in assisted suicide practices. METHODS: A qualitative interview study was conducted with 23 palliative care physicians across Switzerland...

Despite much work in recent years, vehicle emissions remain a significant contributor in many areas where air quality standards are under threat. Policy-makers are actively exploring options for next generation vehicle emission control and local fleet management policies, and new monitoring technologies to aid these activities. Therefore, we report here on findings from two separate but complementary blind evaluation studies of one new-to-market real-world monitoring option, HEAT LLC's Emission Detection And Reporting system or EDAR, an above-road open path instrument that uses Differential Absorption LIDAR to provide a highly sensitive and selective measure of passing vehicle emissions...

In view of the already existing and the expected growing costs due to the pathological osteoarthritic joint alterations and the related consequences, preventive and conservative strategies which can avoid or delay osteoarthritic joint alterations are welcomed from a socio-economical perspective. Here, it should be mentioned that corresponding primary prevention measures should take place early by already educating children about a healthy diet and motivating them to regular physical exercise. In overt or symptomatic osteoarthritis a good joint function and reduction of disease-related pain as well as a delay in the progression of osteoarthritis should be the primary goals of non-surgical therapeutic approaches...

Therapeutic exercises in osteoarthritis (OA) are therapeutic approach with proven efficacy. On the other hand, the different disease form, the lack of established consensus and system for patient education limit the widespread use of therapeutic exercises in clinical practice. The mechanisms of action of therapeutic exercise in OA include the following components e. g., neuromuscular (improvement of proprioception, muscle strength and joint stability), intra-articular (prevention of cartilage degeneration, antiinflammatory effect, improvement of the quality of the joint fluid), periarticular, general health with reduction of cardiovascular risk and psychological components...
