International Exercise Recommendations in Older Adults (ICFSR): Expert Consensus Guidelines.

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.

Physical Frailty: ICFSR International Clinical Practice Guidelines for Identification and Management.

OBJECTIVE: The task force of the International Conference of Frailty and Sarcopenia Research (ICFSR) developed these clinical practice guidelines to overview the current evidence-base and to provide recommendations for the identification and management of frailty in older adults. METHODS: These recommendations were formed using the GRADE approach, which ranked the strength and certainty (quality) of the supporting evidence behind each recommendation. Where the evidence-base was limited or of low quality, Consensus Based Recommendations (CBRs) were formulated. The recommendations focus on the clinical and practical aspects of care for older people with frailty, and promote person-centred care. Recommendations for Screening and Assessment: The task force recommends that health practitioners case identify/screen all older adults for frailty using a validated instrument suitable for the specific setting or context (strong recommendation). Ideally, the screening instrument should exclude disability as part of the screening process. For individuals screened as positive for frailty, a more comprehensive clinical assessment should be performed to identify signs and underlying mechanisms of frailty (strong recommendation). Recommendations for Management: A comprehensive care plan for frailty should address polypharmacy (whether rational or nonrational), the management of sarcopenia, the treatable causes of weight loss, and the causes of exhaustion (depression, anaemia, hypotension, hypothyroidism, and B12 deficiency) (strong recommendation). All persons with frailty should receive social support as needed to address unmet needs and encourage adherence to a comprehensive care plan (strong recommendation). First-line therapy for the management of frailty should include a multi-component physical activity programme with a resistance-based training component (strong recommendation). Protein/caloric supplementation is recommended when weight loss or undernutrition are present (conditional recommendation). No recommendation was given for systematic additional therapies such as cognitive therapy, problem-solving therapy, vitamin D supplementation, and hormone-based treatment. Pharmacological treatment as presently available is not recommended therapy for the treatment of frailty.

Prevention of Disability in the Frail Chinese Older Population.

As aging is becoming a global phenomenon, the burden of population aging is increasing rapidly, and is soon expected to be the highest in low-and middle-income countries. China represents the world's largest population, and will face the largest number of older individuals, while the economy still remains developing. There is an urgent need to address the negative consequences of aging such as disability, that creates a myriad of challenges, including financial burden to the economy. In order to achieve successful aging-i.e., aging without being frail or disabled, the traditional healthcare model based on a disease-centered approach is not enough, but require a more holistic course. Here, we briefly outline the current scenario of aging and disability in the Chinese older population, its impact and challenges. We strongly believe that public health initiatives centered on frailty, a clinically distinguishable state of extreme vulnerability in older adults, could be the most relevant approach to meet the current needs of the aging population. Such initiatives are immediately needed to reshape the existing model of geriatric healthcare, to promote healthy aging and to reduce the burden of disability in the Chinese population.

International Clinical Practice Guidelines for Sarcopenia (ICFSR): Screening, Diagnosis and Management.

OBJECTIVES: Sarcopenia, defined as an age-associated loss of skeletal muscle function and muscle mass, occurs in approximately 6 - 22 % of older adults. This paper presents evidence-based clinical practice guidelines for screening, diagnosis and management of sarcopenia from the task force of the International Conference on Sarcopenia and Frailty Research (ICSFR). METHODS: To develop the guidelines, we drew upon the best available evidence from two systematic reviews paired with consensus statements by international working groups on sarcopenia. Eight topics were selected for the recommendations: (i) defining sarcopenia; (ii) screening and diagnosis; (iii) physical activity prescription; (iv) protein supplementation; (v) vitamin D supplementation; (vi) anabolic hormone prescription; (vii) medications under development; and (viii) research. The ICSFR task force evaluated the evidence behind each topic including the quality of evidence, the benefit-harm balance of treatment, patient preferences/values, and cost-effectiveness. Recommendations were graded as either strong or conditional (weak) as per the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Consensus was achieved via one face-to-face workshop and a modified Delphi process. RECOMMENDATIONS: We make a conditional recommendation for the use of an internationally accepted measurement tool for the diagnosis of sarcopenia including the EWGSOP and FNIH definitions, and advocate for rapid screening using gait speed or the SARC-F. To treat sarcopenia, we strongly recommend the prescription of resistance-based physical activity, and conditionally recommend protein supplementation/a protein-rich diet. No recommendation is given for Vitamin D supplementation or for anabolic hormone prescription. There is a lack of robust evidence to assess the strength of other treatment options.

Aspectos metodológicos de los procesos asistenciales integrados (PAI) / Methodological aspects of integrated care pathways

Un proceso asistencial integrado (PAI) es una herramienta cuyo propósito es aumentar la efectividad de las actuaciones clínicas a través de una mayor coordinación y garantía de continuidad asistencial. Los PAI sitúan al paciente como el eje central de la organización asistencial. Se definen como el conjunto de actividades que realizan los proveedores de la atención sanitaria con la finalidad de incrementar el nivel de salud y el grado de satisfacción de la población que recibe los servicios. La elaboración de un PAI precisa analizar el flujo de actividades, la interrelación entre profesionales y dispositivos asistenciales y las expectativas del paciente. En este artículo se presenta y se discute la metodología para la elaboración de un PAI, así como los factores de éxito para su definición y su efectiva implantación. Se explica también, a modo de ejemplo, el reciente PAI para hipoglucemias en personas con diabetes mellitus tipo 2 elaborado por un equipo multidisciplinar y avalado por varias sociedades científicas (AU)

Treatment with acarbose may improve endothelial dysfunction in streptozotocin-induced diabetic rats.

We sought to determine whether a single reduction of hyperglycemia and those derivatives from nonenzymatic protein glycosylation may be effective in reducing the development of diabetic endothelial dysfunction. Therefore, we investigated how acarbose, an inhibitor of intestinal alpha-glucosidase that reduce hyperglycemia by lowering glucose absorption, may prevent the impairment of acetylcholine (ACh)-induced endothelium-dependent relaxations observed in isolated vascular segments from untreated streptozotocin-induced diabetic rats. When administered after diabetes induction, 10 mg/kg acarbose decreased modestly the enhancement of blood glucose and glycosylated hemoglobin (HbA1c) levels, but not those of advanced glycosylation end products (AGEs). This effect was linked to a partial improvement of ACh-induced responses both in conductance vessels, such as aortic segments, and resistance vasculature, like mesenteric microvessels. When acarbose was introduced after 6 weeks of untreated diabetes, blood glucose, HbA1c, and AGE levels were not affected and endothelial dysfunction remained unchanged in mesenteric microvessels, whereas a small improvement was observed in aortic segments. The addition of 100 U/ml superoxide dismutase enhanced the impaired relaxations to values similar to vessels from nondiabetic rats, indicating a main role for superoxide anions in diabetes-induced endothelial dysfunction. We conclude that hyperglycemia itself or elevated HbA1c, but not plasma AGEs, are related to enhanced oxidative stress and to the impairment of endothelium function associated to diabetes. This process can be partially prevented by reducing glucose absorption with acarbose.

Nisoldipine CC: clinical experience in hypertension.

Nisoldipine coat core (CC) is a long-acting formulation of the dihydropyridine calcium channel blocker nisoldipine, suitable for once-daily administration in the treatment of patients with hypertension. Data are reported from three randomized, controlled trials. In two of these, nisoldipine CC was shown to be equivalent in efficacy and tolerability to atenolol in patients with mild to moderate hypertension and to enalapril in elderly patients with hypertension. In a third study using ambulatory blood pressure monitoring in black patients with severe hypertension, nisoldipine CC maintained blood pressure control over the 24-hour dosing period. In addition, regression of left ventricular (LV) mass and improvement in LV function were observed at the end of the 4-month treatment period. Further data are presented from a pharmacokinetic pharmacodynamic modelling study investigating the potential effects of dose-dumping of nisoldipine from the controlled-release formulation, which may occur when the drug is taken with food. This study illustrates the superior control of plasma nisoldipine concentrations and blood pressure provided by the CC compared with an immediate-release formulation, and indicates that an interaction between nisoldipine CC and food is unlikely to cause adverse events. The results of these trials provide further support for the use of nisoldipine CC as an effective agent for the treatment of patients with hypertension, providing consistent antihypertensive efficacy and good tolerability with once-daily administration.

[A multicenter study comparing nitrendipine and chlorthalidone in elderly hypertensive patients]. / Estudio multicéntrico comparativo entre nitrendipino y clortalidona en pacientes ancianos hipertensos.

One hundred and eleven low-moderate hypertense elderly patients treated with nitrenpidine or chlortalidone were studied during 4 months either on monotherapy or in combination according to the therapeutic response observed. The therapeutic goal (diastolic arterial pressure less than 95 mmHg) was obtained in 92.4% of patients on nintrenpidine and in 49.1% on chlortidone, both on monotherapy (2 months) (p less than 0.001). At the end of the study 96.3% of patients reaches the therapeutic goal. Secondary effects were observed in 8.3% of patients on nitrenpidine and 6.1% on chlortalidone and in 11.1% of patients on combined treatment. No abnormalities were observed in blood biochemistry studied nor was there evidence of a significant influence of any of the two drugs on the patients quality of life which was evaluated through a specific questionnaire specially designed.
