Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.
Researchers at McMaster University (Hamilton, ON) explored whether a surgeon's expertise influences procedural choice. The results of a new study of more than 8000 non-small cell lung cancer (NSCLC) patients undergoing surgical resection by 124 physicians showed that surgeons who perform more surgeries are less likely to perform high-risk pneumonectomies. Christian J. Finley, MD, MPH, will be presenting the results of this research at the 95th AATS Annual Meeting in Seattle, WA on April 28, 2015.
Post-surgical hospital readmission after discharge and repeat emergency room (ER) visits are not unusual for patients who have undergone major thoracic surgery. Recognizing this problem, clinicians at McMaster University have implemented an innovative, active post-discharge intervention for thoracic surgery patients that is based on the principle of a "one team-one approach" that is initiated while the patient is still hospitalized.
New evidence suggests that lung cancer surgery patients are at higher risk of developing venous thromboembolism, including deep vein thrombosis (DVT) and pulmonary embolism (PE), than previously thought, with elevated risks of complications or death. When thromboemboli occur, they may be asymptomatic or attributed to post-surgical pain or complications, and may reflect both the lung cancer itself as well as compromised lung function after surgery.
Latino adults with diabetes who participated in a church-based education program reported eating less high-fat food and exercising more following a trial intervention program run by researchers from University of Chicago's Department of Medicine.
A retrospective review of 633 adults and children who underwent bioprosthetic pulmonary valve replacement (PVR) for congenital heart disease between 1996 and 2014 indicated that the risk of re-intervention was five times greater for children than adults, with the likelihood of re-intervention decreasing by 10% for each increasing year of age at surgery.
Yale researchers successfully corrected the most common mutation in the gene that causes cystic fibrosis, a lethal genetic disorder. The study was published April 27 in Nature Communications.
Medical experts widely recommended a combined program of diet and fitness to fight obesity. But when it comes to the type of exercise most effective a reducing weight and body mass—strength training, endurance exercise or a combination of both—opinions vary widely on which exercise regimen is best.
Ultrasound—the technology used for sonograms and examining the heart—can increase the rate at which heart cells beat, researchers from Drexel University report.
An enzyme secreted by the body's fat tissue controls energy levels in the brain, according to new research at Washington University School of Medicine in St. Louis. The findings, in mice, underscore a role for the body's fat tissue in controlling the brain's response to food scarcity, and suggest there is an optimal amount of body fat for maximizing health and longevity.
Calorie restriction has long been studied as a way to extend lifespan in animals. It has been associated with the ability to reduce the risks of cardiovascular and other diseases and to improve overall health.
Previous guidelines from the American Thyroid Association for evaluating and managing thyroid nodules and thyroid cancers targeted adults. Recognizing the potential differences in clinical presentation and long-term outcomes, and the potential risks of overly aggressive therapy in pediatric patients with thyroid cancer, an ATA Task Force developed management guidelines for children with thyroid nodules and differentiated thyroid cancer (DTC), which are published in Thyroid, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers and the official journal of the American Thyroid Association.
Vasoproliferative ocular diseases are responsible for sight loss in millions of people in the industrialised countries. Many patients do not currently respond to the treatment offered, which targets a specific factor, VEGF. A team of Inserm researchers at the Vision Institute (Inserm/CNRS/Pierre and Marie Curie University), in association with a team from the Yale Cardiovascular Research Center, have demonstrated in an animal model that blocking another protein, Slit2, prevents the pathological blood vessel development that causes these diseases.
In a promising breakthrough for smokers who are trying to quit, neuroscientists at the University of Massachusetts Medical School and The Scripps Research Institute have identified circuitry in the brain responsible for the increased anxiety commonly experienced during withdrawal from nicotine addiction.
Individuals with type 2 diabetes, who are resistant to insulin, have an excess blood glucose level, which they are now trying to reduce using a new class of diabetes drugs known as the gliflozins.
UC Davis Assistant Professor Mark Huising is a recipient of The Hartwell Foundation 2014 Individual Biomedical Research Award to support his early-stage research toward a cure for juvenile diabetes. Diabetes affects 10 percent of the entire United States population, including approximately a million children. Remarkably, 40 children every day receive the diagnosis of diabetes.
Researchers from Montefiore Health System and Albert Einstein College of Medicine will present new findings on how to effectively treat migraine, and forecast the onset of pain in a number of neurological conditions including dementia in older adults.
Two of Louisville's leading heart physicians will host a one-day symposium designed to provide the community, physicians, nurses and health professionals up-to-date information on the prevention, diagnosis and treatment of cardiovascular disease in women.
Genomic studies have illuminated the ways in which malfunctioning genes can drive cancer growth while stunting the therapeutic effects of chemotherapy and other treatments. But new findings from Weill Cornell Medical College investigators indicate that these genes are only partly to blame for why treatment that was at one point effective ultimately fails for about 40 percent of patients diagnosed with the most common form of non-Hodgkin Lymphoma.
Every year, more than 120 million prescriptions are written worldwide for thiazide drugs, a group of salt-lowering medicines used to treat high blood pressure. These drugs are often work very well, and over decades have saved hundreds of thousands of lives.
Parent Project Muscular Dystrophy, a nonprofit organization leading the fight to end Duchenne muscular dystrophy (Duchenne) awarded University of Washington a $148,000 grant to continue the functional analysis of spectrin-like repeats in dystrophin.
