Sarcopenia

This book offers a concise and updated guide for all readers (physicians and non-physicians) interested in gaining a comprehensive and precise understanding of sarcopenia. Over the last several years, sarcopenia has increasingly developed from being a concept known only in research settings to one that is commonly explored in journals and scientific meetings for various disciplines, such as geriatrics, rheumatology and rehabilitation medicine. Thus, all domains of sarcopenia, from molecular aspects to clinical management, represent highly active areas of research and clinical practice for health professionals in a variety of fields, including geriatric medicine, nutrition, and epidemiology. Despite being a relatively new concept in medicine, sarcopenia is increasingly being recognized as an important determinant of other health conditions, including mortality and disability. This book, written by experts from around the globe, covers several core aspects of sarcopenia management, from molecular mechanisms to genetics, epidemiology, diagnosis and finally treatment, including the clinical impact of sarcopenia as a risk factor, the known genetic and molecular aspects that can aid in predicting sarcopenia, and selected treatment and therapy concepts, including indications for nutrition and physical exercise. Sharing data from the latest studies, it will be of considerable interest not only for geriatricians, but also for a wide range of other readers.

Sarcopenia: Molecular, Cellular, and Nutritional Aspects describes the progressive loss of skeletal muscle mass and strength, defined by Rosenberg in 1997 as a hallmark of aging and referred to as “sarcopenia.” As life expectancy continues to increase worldwide, sarcopenia has become a major public health issue. The condition worsens in the presence of chronic diseases accelerating its progression. Sarcopenia is not considered to be “a process of normative aging” but according to the International Classification of Disease, Tenth Revision, Clinical Modification (ICD-10-CM), as a disease. As sarcopenia is an ineluctable process, prevention and management are the only options to promote healthy aging; these actions should perhaps be taken during youth. Included in this book: · Features essential information on sarcopenia, its current definition, and molecular and cellular aspects of this disease · Discusses the development of physical frailty, a complication of sarcopenia, and predicts its occurrence in the older population · Presents alterations in muscle protein turnover and mitochondrial dysfunction in the aging process · Provides data on the negative involvement of sarcopenia in certain chronic diseases · Describes presbyphagia or age-related changes in the swallowing mechanism in older people · Details possible strategies to combat muscle wasting in healthy older adults and their limits This book features information collected from pioneers or experts on human aging from around the globe, including Europe, Brazil, Canada, Japan and the United States. It is a valuable source of information for nutritional scientists, medical doctors, sports scientists, food scientists, dietitians, students in these fields, and for anyone interested in nutrition. We hope this book provides a better understanding of sarcopenia which inevitably occurs with aging without weight loss. Moreover, this book will supply information outlining strategies to prevent or limit muscle wasting due to normal aging in order to promote successful aging.

Take control of your physical and brain health with low-level strength training We all know that we lose muscle mass as we age. But did you know that sarcopenic obesity (a.k.a. being “skinny fat”) is linked to increasing your risk of developing dementia and/or Alzheimer’s? Not only is losing muscle bad for your body, it’s also bad for your brain. Don’t let muscle deterioration negatively affect your future. It’s time to take your physical and brain health into your own hands with strength training. This book is full of tips, techniques, and easy-to-follow strength-training routines to fight sarcopenia. From beginners to those already comfortable using weights, this book has solutions for everyone. Lose fat, improve muscle tone, and strengthen bones while guarding against sarcopenia and its negative impact on your body and your brain. This book makes it easy to regain the muscle mass you need to live a healthier and longer life.

Some of the most serious consequences of aging are its effects on skeletal muscle. ‘Sarcopenia’, the progressive age-related loss of muscle mass and associated muscle weakness, renders frail elders susceptible to serious injury from sudden falls and fractures and at risk for losing their functional independence. Not surprisingly, sarcopenia is a significant public health problem throughout the developed world. There is an urgent need to better understand the neuromuscular mechanisms underlying age-related muscle wasting and to develop therapeutic strategies that can attenuate, prevent, or ultimately reverse sarcopenia. Significant research and development in academic and research institutions and in pharmaceutical companies is being directed to sarcopenia and to related health issues in order to develop and evaluate novel therapeutics. This book provides the latest information on sarcopenia from leading international researchers studying the cellular and molecular mechanisms underlying age-related changes in skeletal muscle and identifies strategies to combat sarcopenia and related muscle wasting conditions and neuromuscular disorders. The book provides a vital resource for researchers and practitioners alike, with information relevant to gerontologists, geriatricians, sports medicine physicians, physiologists, neuroscientists, cell biologists, endocrinologists, physical therapists, allied health and musculoskeletal practitioners, strength and conditioning specialists, athletic trainers, and students of the medical and biomedical sciences.

SARCOPENIA An in-depth examination of sarcopenia’s underexplored yet widespread impact within the field of gerontology Sarcopenia is common in older men and women, and yet awareness of its clinical relevance is still relatively low. Only formally included in the International Classification of Diseases in 2016, the condition may impact societies with serious health-related and financial consequences unless consistent, effective methods of identification and management are adopted. This second edition of Sarcopenia provides geriatricians and other healthcare professionals with a revised and expanded examination of this understudied and underdiagnosed condition. Edited by two leading authorities on the subject, it covers the epidemiology and diagnosis of sarcopenia, as well as treatment options and possible prevention strategies. Eight newly written chapters build upon existing knowledge with fresh data on topics including sarcopenia’s biomarkers and its impact on the healthcare economy. This important text: Defines sarcopenia and explains its clinical relevance Covers all recent scientific evidence Outlines treatment options Considers prevention strategies Discusses sarcopenia as a public health priority Features eight new chapters covering topics such as sarcopenia’s clinical management, its biomarkers, and its financial impact Containing vital information for clinicians and other professionals working in geriatric care, nursing homes, nutrition, cancer, endocrinology, surgery, sports medicine and many other specialties, Sarcopenia, second edition, is a groundbreaking and essential new resource.

Frailty is considered a multisystem impairment that makes an individual vulnerable to external or internal stressors. Sarcopenia, the age-dependent loss of muscle mass and function, is proposed as the biological substrate and the pathway whereby the consequences of physical frailty develop. These syndromes are associated with a negative impact in quality of life and can lead to the occurrence of disability, institutionalization, and even mortality. The book focuses upon all the related aspects of frailty and sarcopenia and the new advancements in the related treatments including complex issues and research. It includes high-quality chapters in all related aspects for the syndromes of sarcopenia and frailty, which adversely affect the function and overall effectiveness of the musculoskeletal system and interventions to promote rehabilitation.

This title includes a number of Open Access chapters. Sarcopenia—the loss of muscle mass and strength that occurs with advancing age—is a major health challenge, particularly in North America, Europe, and Japan, which have large aging populations. This compendium volume is a valuable addition to the existing literature, providing state-of-the-art information on the most effective prevention and treatment options. Included are research articles on nutrition management and the prevention of sarcopenia; protein therapy for sarcopenia; effect of exercise on sarcopenia; and other therapeutic strategies, including antioxidants and steroids.

This open access book aims to provide a comprehensive but practical overview of the knowledge required for the assessment and management of the older adult with or at risk of fragility fracture. It considers this from the perspectives of all of the settings in which this group of patients receive nursing care. Globally, a fragility fracture is estimated to occur every 3 seconds. This amounts to 25 000 fractures per day or 9 million per year. The financial costs are reported to be: 32 billion EUR per year in Europe and 20 billon USD in the United States. As the population of China ages, the cost of hip fracture care there is likely to reach 1.25 billion USD by 2020 and 265 billion by 2050 (International Osteoporosis Foundation 2016). Consequently, the need for nursing for patients with fragility fracture across the world is immense. Fragility fracture is one of the foremost challenges for health care providers, and the impact of each one of those expected 9 million hip fractures is significant pain, disability, reduced quality of life, loss of independence and decreased life expectancy. There is a need for coordinated, multi-disciplinary models of care for secondary fracture prevention based on the increasing evidence that such models make a difference. There is also a need to promote and facilitate high quality, evidence-based effective care to those who suffer a fragility fracture with a focus on the best outcomes for recovery, rehabilitation and secondary prevention of further fracture. The care community has to understand better the experience of fragility fracture from the perspective of the patient so that direct improvements in care can be based on the perspectives of the users. This book supports these needs by providing a comprehensive approach to nursing practice in fragility fracture care.
