Filter by:Tobacco smoke is probably the single most significant source of toxic chemicals that humans are exposed to. Smoking is associated with a variety of pathological conditions such as cardiovascular and pulmonary diseases. In addition to the known harmful effects of cigarette smoking, several epidemiological studies identified tobacco use as a risk factor for sarcopenia, the loss of skeletal muscle mass and strength with advancing age. Previous studies examined skeletal muscles of smokers in comparison with muscles of non-smokers and found structural and metabolic damage in muscles of smokers. Quitting of smoking is known to be associated with weight gain. A previous study examined the effects of smoking cessation on body composition of post-menopausal women using dual-energy x-ray absorptiometry (DEXA). It was found that women who successfully quit smoking for a period of 16 months have significantly increased their body weight, fat mass, muscle mass and functional muscle mass in comparison with non-quitters women. For the first time, it was shown that smoking cessation is associated with an increase of functional muscle mass. Yet, the effects of quitting of smoking on muscle mass and muscle functional capabilities of younger subjects remain unclear. Therefore, we aim to investigate the effects of smoking cessation on muscle mass, muscle function and strength in heavy smoker's subjects. Our findings may shed light on the beneficial effects of smoking cessation regarding the status and function of skeletal muscle in heavy smokers and as a possible strategy to prevent or delay the progression of sarcopenia. Research hypothesis: Smoking cessation among adult heavy smokers will lead to increase in skeletal muscle mass and improvement of muscle function and strength compared with continued smokers.
The purpose of this study is to determine if physical exercise reduces the adverse changes in adipose tissue metabolism and insulin sensitivity that occurs in women during the menopausal transition.
About two-thirds of adults in the United States are overweight or obese with likely adverse health consequences. A Moderate weight loss by dieting and exercise is recommended to improve health. We are interested to know whether eating dietary protein at different times of the day influences changes in body composition, muscle and indices of health. The purpose of this study is to examine the effects of within-day patterning of dietary protein intake (even vs. skewed) on energy-restriction and resistance training-induced changes in body composition, muscle size, appetite, and clinical health (including blood glucose and blood pressure).
Clinical background: Weight loss is a common problem in patients suffering from gastrointestinal cancer. It is demonstrated that the prognosis for cancer patients with weight loss is worse than that for weight stable patients. Malnutrition in cancer patients is associated with a poor prognosis and is an important predictor of mortality. Supplementation with home parenteral nutrition in aphagic and terminal patients has shown improved quality of life, energy balance, body composition and prolonged survival. Aim: The aim of this study is primarily to study the effects of supplementation with parenteral nutrition, to patients with advanced incurable gastrointestinal cancer on lean body-mass and body composition. Patients found to be at nutritional risk will be included in the study and will be randomized to either best supportive nutritional care or best supportive nutritional care and supplemental Parenteral Nutrition. Design: This study is a controlled, randomized trial with two parallel study arms. The study will include patients with advanced GI cancers at nutritional risk, performance status 0-2 and with an expected survival of a minimum of 3 months. A total of 100 patients are planned to be enrolled and randomized to either best supportive nutritional care or best supportive nutritional care and supplemental parenteral Nutrition. Primary endpoint is improvement of lean body mass, and by that improvement of quality of life, performance status and cancer treatment tolerance. Discussion: The planned study will provide important information about the effect of parenteral nutrition in a patient group with advanced gastrointestinal cancer. Palliative treatment strategies are set up to improve quality of life as well as prolongation of life. Parenteral nutrition in this patient group may indeed contribute to both these aspects of palliation.
The purpose of the study is to investigate the effects of Conjugated Linoleic Acid (CLA) from dairy products on fatty acid metabolism and human health. A CLA depletion-repletion study was carried out with healthy volunteers. CLA depletion was achieved through an eight-week dairy fat restriction, followed by an eight-week repletion period consisting of intake of a butter naturally enriched with CLA. Changes in body composition, fasting glucose and insulin, inflammatory mediators, cell membranes' stability, plasma lipid levels and fatty acid composition of lipid classes are evaluated after depletion and repletion phases.
The Austrian LEAD study is the first investigation initiated in Austria that aims to investigate the prevalence and the natural history of COPD in a reference population of Austria.
The aim of the present study is to investigate the effect of endurance on PSA doubling time in prostate cancer patients with an elevation in PSA following radical prostatectomy for localized cancer. Furthermore, underlying mechanisms such as reduction in inflammatory markers and improvement in insulin sensitivity and body composition are investigated.
Resistance exercise (RE) has been proposed as a possible strategy for prevention and rehabilitation of diseases. The increase in both muscle strength and the ability to perform tasks of day-to-day work environment and are well-characterized benefits of this type of training. The literature has been investigating the effectiveness of the RE for humans, yet few studies have been conducted with intellectual disabilities (ID). It is known that a sedentary lifestyle contributes to the development of cardiovascular disease, type 2 diabetes, hypertension, arthritis, and stress, depression, difficulty in socializing, stigma and discrimination. In particular, the ID is less active and is more likely to develop secondary diseases.
This research consists of a novel intervention designed to increase physical activity of premature babies in their first year of life. The potential beneficial impact of augmented physical activity on: 1. Body composition 2. Associated biochemical and cellular mechanisms of growth and inflammation 3. Quality of maternal care will be measured
