    除了骨骼肌在运动和运动中的作用,肌肉在广泛的代谢过程中起着关键作用,这些代谢过程可以改善健康或疾病风险。与年龄相关的肌肉损失被称为肌肉减少症。肌肉是胰岛素刺激的葡萄糖处置的主要部位,是基础代谢率的最大组成部分,直接和间接影响骨密度,产生对肌肉和包括大脑在内的其他组织具有多效性作用的肌细胞因子,并储存在食物摄入减少和压力减少期间维持蛋白质合成所必需的必需氨基酸。因此,骨骼肌健康恶化并不令人惊讶,通常,由于肌肉质量和肌肉力量的下降是慢性疾病的强大风险因素和主要后果,残疾,失去独立性,它是死亡的最大危险因素之一。然而,骨骼肌仍然是所有组织中最具可塑性的组织之一,随着身体活动和不活动而导致的蛋白质合成和降解速率的快速变化,炎症,营养和荷尔蒙状况。这使得药物疗法的发展,以增加肌肉质量(或防止损失),几十年来的重要目标。然而,虽然最近在了解肌肉蛋白质代谢的分子和细胞调节方面取得了显著进展,没有批准的治疗肌肉减少症的药物,影响数百万老年人的骨骼肌损失。本文的目的是描述缺乏新的有效药物疗法来治疗与年龄相关的疾病和失去独立性的最重要风险因素之一的可能原因。
    In addition to the role of skeletal muscle in movement and locomotion, muscle plays a critical role in a broad array of metabolic processes that can contribute to improved health or risk of disease. The age-associated loss of muscle has been termed sarcopenia. The muscle is the primary site of insulin-stimulated glucose disposal and the largest component of basal metabolic rate, directly and indirectly affects bone density, produces myokines with pleiotropic effect on muscle and other tissues including the brain, and stores essential amino acids essential for the maintenance of protein synthesis during periods of reduced food intake and stress. As such, not surprisingly deterioration of skeletal muscle health, typically operationalized as decline of muscle mass and muscle strength is both a powerful risk factor and main consequence of chronic diseases, disability, and loss of independence, and it is one of the strongest risk factors for mortality. However, skeletal muscle remains one of the most plastic of all tissues, with rapid changes in rates of protein synthesis and degradation in response to physical activity and inactivity, inflammation, and nutritional and hormonal status. This has made the development of pharmacological therapies to increase muscle mass (or prevent loss), an important goal for decades. However, while remarkable advances in the understanding of molecular and cellular regulation of muscle protein metabolism have occurred recently, there are no approved drugs for the treatment of sarcopenia, the loss of skeletal muscle affecting millions of older people. The goal of this paper is to describe the possible reasons for the lack of new and effective pharmacotherapies to treat one of the most important risk factors for age-associated disease and loss of independence.

    人类的衰老过程是普遍的,无处不在,不可避免。每个生理功能都在不断减弱。两种不同的衰老表型之间有一定的范围,由生活模式塑造-经验和行为,特别是通过是否存在身体活动(PA)和有组织的锻炼(即,久坐不动的生活方式)。衰老和久坐的生活方式与肌肉功能和心肺健康的下降有关,导致执行日常活动和维持独立运作的能力受损。然而,在存在足够的运动/PA的情况下,随着年龄的增长,肌肉和有氧能力的这些变化显着减弱。此外,结构化运动和整体PA作为许多慢性病的预防策略都发挥着重要作用,包括心血管疾病,中风,糖尿病,骨质疏松,和肥胖;改善流动性,心理健康,和生活质量;降低死亡率,除了其他好处。值得注意的是,运动干预计划改善了虚弱的标志(低体重,力量,移动性,PA水平,能量)和认知,从而优化老化过程中的功能能力。在这些病理条件下,运动被用作治疗剂,并遵循以下原则:确定疾病的原因,然后以循证剂量使用药剂来消除或缓解疾病。因此,PA/结构化练习的处方应基于预期结果(例如,一级预防,健康或功能状态或疾病治疗的改善),个性化,像任何其他医疗一样调整和控制。此外,与其他治疗剂一致,运动显示出剂量反应效应,可以使用不同的方式个性化,适合于健康状态或医疗状况的体积和/或强度。重要的是,运动疗法通常同时针对几个生理系统,而不是像通常的药物治疗方法那样针对单一结果。有的疾病,运动是一种替代药物治疗(如抑郁症),从而有助于解除潜在不适当药物的处方(PIMS).还有其他疾病目前没有有效的药物治疗(如肌肉减少症或痴呆),它可能在预防和治疗中起主要作用。因此,这一共识声明为在老年人中使用运动和PA促进健康和疾病预防和治疗提供了基于证据的理由.运动处方是根据随机对照试验中研究的特定方式和剂量来讨论的,因为它们在减轻衰老的生理变化方面的有效性。疾病预防,和/或改善患有慢性疾病和残疾的老年人。提出了建议,以弥合当前文献中的空白,并优化运动/PA作为预防药物和治疗剂的使用。
    The human ageing process is universal, ubiquitous and inevitable. Every physiological function is being continuously diminished. There is a range between two distinct phenotypes of ageing, shaped by patterns of living - experiences and behaviours, and in particular by the presence or absence of physical activity (PA) and structured exercise (i.e., a sedentary lifestyle). Ageing and a sedentary lifestyle are associated with declines in muscle function and cardiorespiratory fitness, resulting in an impaired capacity to perform daily activities and maintain independent functioning. However, in the presence of adequate exercise/PA these changes in muscular and aerobic capacity with age are substantially attenuated. Additionally, both structured exercise and overall PA play important roles as preventive strategies for many chronic diseases, including cardiovascular disease, stroke, diabetes, osteoporosis, and obesity; improvement of mobility, mental health, and quality of life; and reduction in mortality, among other benefits. Notably, exercise intervention programmes improve the hallmarks of frailty (low body mass, strength, mobility, PA level, energy) and cognition, thus optimising functional capacity during ageing. In these pathological conditions exercise is used as a therapeutic agent and follows the precepts of identifying the cause of a disease and then using an agent in an evidence-based dose to eliminate or moderate the disease. Prescription of PA/structured exercise should therefore be based on the intended outcome (e.g., primary prevention, improvement in fitness or functional status or disease treatment), and individualised, adjusted and controlled like any other medical treatment. In addition, in line with other therapeutic agents, exercise shows a dose-response effect and can be individualised using different modalities, volumes and/or intensities as appropriate to the health state or medical condition. Importantly, exercise therapy is often directed at several physiological systems simultaneously, rather than targeted to a single outcome as is generally the case with pharmacological approaches to disease management. There are diseases for which exercise is an alternative to pharmacological treatment (such as depression), thus contributing to the goal of deprescribing of potentially inappropriate medications (PIMS). There are other conditions where no effective drug therapy is currently available (such as sarcopenia or dementia), where it may serve a primary role in prevention and treatment. Therefore, this consensus statement provides an evidence-based rationale for using exercise and PA for health promotion and disease prevention and treatment in older adults. Exercise prescription is discussed in terms of the specific modalities and doses that have been studied in randomised controlled trials for their effectiveness in attenuating physiological changes of ageing, disease prevention, and/or improvement of older adults with chronic disease and disability. Recommendations are proposed to bridge gaps in the current literature and to optimise the use of exercise/PA both as a preventative medicine and as a therapeutic agent.

  • 文章类型: English Abstract
    In 2014 the European Society of Cardiology (ESC) and the European Society of Anaesthesiology (ESA) published an update of the guidelines on \"non-cardiac surgery: cardiovascular assessment and management\". Epidemiological data underline the relevance of these guidelines: a total of 5.7 million surgical procedures are performed per year in patients with increased cardiac risk and approximately 167,000 cardiac complications occur per year in Europe of which 19,000 are life-threatening. This new version of the guidelines highlights the patient characteristics, such as functional capacity and comorbidities and procedure-specific aspects for perioperative risk stratification. Decision-making for preoperative stress tests and coronary angiography has been simplified, procedure-specific risks have been revised and the role of multidisciplinary teamwork for high risk procedures is emphasized. A standardized stepwise approach on how to stratify patient-specific and procedure-associated risks has been established. For the first time, the guidelines recommend perioperative regimens on dual antiplatelet therapy and the new oral anticoagulants (NOAC).
