Filter by:Protein-energy malnutrition (PEM) occurs in 65-90% of patients with liver cirrhosis. Severity of malnutrition correlates with progression of liver disease and leads to sarcopenia in 30-70% of cirrhotic patients. Malnutrition and sarcopenia are associated with an increased risk of complications and mortality. In cirrhosis the gut microbiome is altered leading to increased gut permeability, bacterial translocation and inflammation. Since the microbiome is involved in nutrient uptake and metabolism, it is hypothesized that microbiome alterations contribute to sarcopenia. A prospective controlled cohort study to investigate the interrelation of microbiome changes and sarcopenia in cirrhosis will be conducted. Furthermore the effect of nutritional interventions on the microbiome in cirrhosis will be studied. From this study information on how the gut microbiome composition and sarcopenia are associated in cirrhosis and if modulation of the gut microbiome by nutritional interventions is feasible will be collected.
Age-associated loss of muscle mass, termed sarcopenia, is strongly associated with functional impairment and physical disability in the elderly. Maintenance or growth of muscle mass is mainly driven by increased muscle protein synthesis (i.e. the generation of new muscle protein) in response to exercise and feeding. However, several investigations have shown that elderly individuals have a blunted protein synthetic response following protein intake. This inability of the elderly to properly respond to growth stimuli has been termed anabolic resistance and plays a significant role in the development of sarcopenia. However, the precise mechanisms underpinning anabolic resistance are unknown. It is well established that muscle protein synthesis at the molecular level is regulated by a cellular protein complex called mTORC1. When exposed to a growth stimulus, mTORC1 has been shown to associate with lysosomes, i.e. the intracellular organelles responsible for the breakdown of cellular proteins, and subsequently moving towards the cell periphery. This movement of lysosome-associated mTORC1 within the cell is believed to be vital for the activation of protein synthesis, as inhibition of lysosomal movement blunts mTORC1 activation in response to amino acids. Thus, dysregulation of lysosomal movement in ageing muscle may represent an underlying mechanism in the development of anabolic resistance. However, this area of research is unexplored in the context of human skeletal muscle. The investigators hypothesize that dysregulation of lysosomal movement plays a central role in the development of age-associated skeletal muscle anabolic resistance.
The purpose of this study is to determine the prevalence of malnutrition and/or sarcopenia at admission to the hospital in older adults.
Lung cancer (LC) is usually diagnosed in advanced stages and continues to be the leading cause of cancer related deaths worldwide. Cancer cachexia are frequent among patients with LC affecting up to 80% of patients with advanced stage disease, and it has been related with higher risk of complications, length of hospital stay, and worst overall survival. During cancer cachexia, both muscle and fat mass can be wasted, however, the loss of muscle mass has been associated to higher treatment related toxicity, loss of functional status, shorter progression free survival and overall survival in different types of cancer under various treatments. Hence, preservation of muscle mass and function should be an important focus of the multidisciplinary treatment of patients with LC. Pulmonary rehabilitation (PR) has been known to improve pulmonary function, reduce fatigue and improve exercise tolerance in patients with LC undergoing curative surgery. However, few studies have focused on the efficacy of PR on patients with advanced cancer undergoing palliative care with chemotherapy or targeted therapies.
The purposes of this study were to investigate the prevalence and risk factors for sarcopenia in Chinese adults and elderly, and evaluate the effect of Lifestyle Modification Project (LMP) on Clinical Outcomes, Quality of Life and Cost-effectiveness Ratio.
This study evaluate the association of body composition (mainly free-fat mass), clinical and biochemical parameters with development of toxicity in patients under treatment with Carboplatin/Paclitaxel in advanced NSCLC.
Feeding optimization and nutritional assessment in patients with severe heart failure are challenging. The prevalence of cardiac cachexia may be underestimated by simple measurements of body weight and body mass index because many patients show relative reductions in muscle mass despite being of normal overall weight. Body composition measurement can be essential in chronic heart failure (CHF) patients to estimate sarcopenia. Chronic heart failure patients with cardiac cachexia have a mortality two to three times higher than noncachectic patients. Bedside body composition measurements can reveal developing cardiac cachexia hence can be useful in prevention.
The purpose of this study was to examine the effects of resistance training on sarcopenic obesity in older women.
The SPRINTT study will evaluate the efficacy of a multicomponent intervention programme (physical activity, nutritional counselling/dietary intervention, and information and communications technology intervention) compared with a healthy aging lifestyle education programme on mobility disability, in non-disabled older people with physical frailty and sarcopenia.
Objective: To study the acute and chronic effects of whole-body vibration (WBV) exercises on the lower extremity blood flow, mobility function, balance, muscle strength, bone density, and general health status, and its feasibility as an intervention in frail elderly patients. Design: Randomized controlled trial. Subjects: The frail older persons meeting the Fried Frailty Criteria. Interventions: All eligible subjects were randomly assigned to 4 groups: (1) WBV group: Subjects received a whole-body vibration exercise alone; (2) Progressive resistance training (PRT) group: Subjects received progressive resistance training; (3) WBV+ PRT group: Subjects received the whole-body vibration and progressive resistance training; (4) Control group: Subjects received no intervention/training. The periods of intervention are 12 weeks. Main measures: The lower extremities blood flow (the diameters and red blood cell velocity of the common femoral artery), timed up and go test, 30-second chair stand test, five times sit to stand test, lower extremities muscle strength, balance function, balance confidence, bone density, and general health status was assessed at the beginning of the study, at instant, 12 weeks and 24 month after the intervention. Study hypothesis: Whole-body vibration exercise is a safe and effective method that can improve the lower extremity blood flow, mobility function, balance, muscle strength, bone density, and general health status in the frail elderly.
