The population is ageing worldwide at a phenomenal pace from 900 million ≥ 60 years old in 2015 to 2 billion in 2050 (1). The longer lifespan is due to advancement in public health, medical, social and economic development. However, healthspan has been slow to improve in most countries where the last decade of life is spent in poor health (2). Aging is associated with declines in functional capacity, and preserving function including lengthening healthspan is an increasingly important challenge for countries with a fast aging population. The World Report on Ageing and Health by World Health Organisation (WHO) defines healthy ageing as the process of developing and maintaining functional ability that enables wellbeing (3). The interaction between individual’s intrinsic capacity and environmental characteristics are crucial to achieve the optimum trajectory which can be modified to maintain a person’s functional ability and intrinsic capacity throughout the life course. We assert that greater knowledge of the effects of the exercise interventions on age-related amelioration of intrinsic capacity domains (i.e locomotion, vitality, cognition, psychological, sensory) that is present in the frail will allow a more coherent and holistic approach to treatment of the frail. This Viewpoint emphasizes the idea that the physiological bases underlying the assertions that exercise treatment of frailty directed at increasing muscle mass by pharmaceuticals in order to treat symptoms of frailty is an example of current medical, scientific and pharmaceutical industrial lack of appreciation of the role of exercise as a therapeutic agent having a major role both in the treatment and prevention not only of disease but also in functional capacity (4, 5).

Summary Rationale This initiative is focused on building a global consensus around core diagnostic criteria for malnutrition in adults in clinical settings. Methods In January 2016, the Global Leadership Initiative on Malnutrition (GLIM) was convened by several of the major global clinical nutrition societies. GLIM appointed a core leadership committee and a supporting working group with representatives bringing additional global diversity and expertise. Empirical consensus was reached through a series of face‐to‐face meetings, telephone conferences, and e‐mail communications. Results A two‐step approach for the malnutrition diagnosis was selected, i.e., first screening to identify “at risk” status by the use of any validated screening tool, and second, assessment for diagnosis and grading the severity of malnutrition. The malnutrition criteria for consideration were retrieved from existing approaches for screening and assessment. Potential criteria were subjected to a ballot among the GLIM core and supporting working group members. The top five ranked criteria included three phenotypic criteria (weight loss, low body mass index, and reduced muscle mass) and two etiologic criteria (reduced food intake or assimilation, and inflammation or disease burden). To diagnose malnutrition at least one phenotypic criterion and one etiologic criterion should be present. Phenotypic metrics for grading severity as Stage 1 (moderate) and Stage 2 (severe) malnutrition are proposed. It is recommended that the etiologic criteria be used to guide intervention and anticipated outcomes. The recommended approach supports classification of malnutrition into four etiology‐related diagnosis categories. Conclusion A consensus scheme for diagnosing malnutrition in adults in clinical settings on a global scale is proposed. Next steps are to secure further collaboration and endorsements from leading nutrition professional societies, to identify overlaps with syndromes like cachexia and sarcopenia, and to promote dissemination, validation studies, and feedback. The diagnostic construct should be re‐considered every 3–5 years.

AbstractAimthe the International Position Statement provides the opportunity to summarise all existing clinical trial and best practice evidence for older people with frailty and diabetes. It is the first document of its kind and is intended to support clinical decisions that will enhance safety in management and promote high quality care. Methodsthe Review Group sought evidence from a wide range of studies that provide sufficient confidence (in the absence of grading) for the basis of each recommendation. This was supported by a given rationale and key references for our recommendations in each section, all of which have been reviewed by leading international experts. Searches for any relevant clinical evidence were generally limited to English language citations over the previous 15 years. The following databases were examined: Embase, Medline/PubMed, Cochrane Trials Register, Cinahl, and Science Citation. Hand searching of 16 key major peer-reviewed journals was undertaken by two reviewers (AJS and AA) and these included Lancet, Diabetes, Diabetologia, Diabetes Care, British Medical Journal, New England Journal of Medicine, Journal of the American Medical Association, Journal of Frailty & Aging, Journal of the American Medical Directors Association, and Journals of Gerontology - Series A Biological Sciences and Medical Sciences. Resultstwo scientific supporting statements have been provided that relate to the area of frailty and diabetes; this is accompanied by evidence-based decisions in 9 clinical domains. The Summary has been supported by diagrammatic figures and a table relating to the inter-relations between frailty and diabetes, a frailty assessment pathway, an exercise-based programme of intervention, a glucose-lowering algorithm with a description of available therapies. Conclusionswe have provided an up to date evidence-based approach to practical decision-making for older adults with frailty and diabetes. This Summary document includes a user-friendly set of recommendations that should be considered for implementation in primary, community-based and secondary care settings.

AbstractAppetite loss/anorexia of aging is a highly prevalent and burdensome geriatric syndrome that strongly impairs the quality of life of older adults. Loss of appetite is associated with several clinical conditions, including comorbidities and other geriatric syndromes, such as frailty. Despite its importance, appetite loss has been under-evaluated and, consequently, under-diagnosed and under-treated in routine clinical care. The International Conference on Frailty and Sarcopenia Research (ICFSR) Task Force met virtually on September 27th 2021 to debate issues related to appetite loss/anorexia of aging. In particular, topics related to the implementation and management of appetite loss in at-risk older adult populations, energy balance during aging, and the design of future clinical trials on this topic were discussed. Future actions in this field should focus on the systematic assessment of appetite in the care pathway of older people, such as the Integrated Care for Older People (ICOPE) program recommended by the World Health Organization. Moreover, clinical care should move from the assessment to the treatment of appetite loss/anorexia. Researchers continue to pursue their efforts to find out effective pharmacologic and non-pharmacologic interventions with a favorable risk/benefit ratio.

The early identification of seniors at high risk of geriatric syndromes is fundamental for targeting interventions to those who most need them. To date, the predictive value of the Short Physical Performance Battery (SPPB) for multifactorial clinical conditions has not been clearly established. Thus, the aim of the present study was to determine whether the SPPB could identify frailty and predict geriatric syndromes in community-dwelling older adults. Participants comprised men and women aged 60 years and older who participated in the Health and Well-being and Aging Survey in Colombia 2015 (n=4125, 57.6% women). A structured interview was administered to obtain socio-demographic data which included age, sex, ethnicity, socioeconomic status, and urbanicity. The study included the measurement of body mass, grip strength, SPPB, Lawton's instrumental ADL scale, specific subjective memory complaints (SSMC), frailty phenotype (Fried and FRAIL Scale), and self-reported falls, geriatric syndromes and/or medical conditions. ROC analysis was used to examine the ability of the SPPB test to predict frailty and geriatric syndromes. The cutoff that maximized both sensitivity and specificity for the frailty phenotype was 8 points or below for men and 7 points or below for women. These cutoff values significantly predicted four geriatric syndromes in descending order: mild dementia (♀ ORajus 3.34, and ♂ ORajus 2.79), low grip strength (♀ ORajus 1.98, and ♂ ORajus 2.45), falls (♀ ORajus 1.39, and ♂ ORajus 1.49), and SSMC (♀ ORajus 1.39). In summary, the main finding of the present study was that SPPB score (i.e., ≤ 8 ♀ and ≤ 7 ♀) seems to be a useful measure for identifying the physical frailty phenotype and predicting geriatric syndromes in community-dwelling older adults.

Frailty is a commonly used term indicating older persons at increased risk for adverse outcomes such as onset of disability, morbidity, institutionalisation or mortality or who experience a failure to integrate adequate responses in the face of stress. Although most physicians caring for older people recognize the importance of frailty, there is still a lack of both consensus definition and consensual clinical assessment tools. The aim of the present manuscript was to perform a comprehensive review of the definitions and assessment tools on frailty in clinical practice and research, combining evidence derived from a systematic review of literature along with an expert opinion of a European, Canadian and American Geriatric Advisory Panel (GAP). There was no consensus on a definition of frailty but there was agreement to consider frailty as a pre-disability stage. Being disability a consequence rather than the cause of frailty, frail older people do not necessary need to be disabled. The GAP considered that disability (as a consequence of frailty) should not be included in frailty definitions and assessment tools. Although no consensual assessment tool could be proposed, gait speed could represent the most suitable instrument to be implemented both in research and clinical evaluation of older people, as assessment of gait speed at usual pace is a quick, inexpensive and highly reliable measure of frailty.

There is a need for a rapid screening test for mild cognitive impairment (MCI) and dementia to be used by primary care physicians. The Rapid Cognitive Screen (RCS) is a brief screening tool (< 3 min) for cognitive dysfunction. RCS includes 3-items from the Veterans Affairs Saint Louis University Mental Status (SLUMS) exam: recall, clock drawing, and insight. Study objectives were to: 1) examine the RCS sensitivity and specificity for MCI and dementia, 2) evaluate the RCS predictive validity for nursing home placement and mortality, and 3) compare the RCS to the clock drawing test (CDT) plus recall. Patients were recruited from the St. Louis, MO Geriatric Research Education and Clinical Center (GRECC), Veterans Affairs Medical Center (VAMC) hospitals (study 1) or the Saint Louis University Geriatric Medicine and Psychiatry outpatient clinics (study 2). Study 1 participants (N=702; ages 65–92) completed cognitive evaluations and 76% (n=533/706) were followed up to 7.5 years for nursing home placement and mortality. Receiver operator characteristic (ROC) curves were computed to determine sensitivity and specificity for MCI (n=180) and dementia (n=82). Logistic regressions were computed for nursing home placement (n=31) and mortality (n=176). Study 2 participants (N=168; ages 60–90) completed the RCS and SLUMS exam. ROC curves were computed to determine sensitivity and specificity for MCI (n=61) and dementia (n=74). RCS predicted dementia and MCI in study 1 with optimal cutoff scores of ≤ 5 for dementia (sensitivity=0.89, specificity=0.94) and ≤ 7 for MCI (sensitivity=0.87, specificity=0.70). The CDT plus recall predicted dementia and MCI in study 1 with optimal cutoff scores of ≤ 2 for dementia (sensitivity=0.87, specificity=0.85) and ≤ 3 for MCI (sensitivity=0.62, specificity=0.62). Higher RCS scores were protective against nursing home placement and mortality. The RCS predicted dementia and MCI in study 2. The 3-item RCS exhibits good sensitivity and specificity for the detection of MCI and dementia, and higher cognitive function on the RCS is protective against nursing home placement and mortality. The RCS may be a useful screening instrument for the detection of cognitive dysfunction in the primary care setting.

Sarcopenia is a loss of muscle protein mass and loss of muscle function. It occurs with increasing age, being a major component in the development of frailty. Current knowledge on its assessment, etiology, pathogenesis, consequences and future perspectives are reported in the present review. On-going and future clinical trials on sarcopenia may radically change our preventive and therapeutic approaches of mobility disability in older people.

The SARC-F scale is a newly developed tool to diagnose sarcopenia and obviate the need for measurement of muscle mass. SARC-F ≥ 4 is defined as sarcopenia. The questions of SARC-F cover physical functions targeting sarcopenia or initial presentation for sarcopenia. The aim of the study is to explore the application of SARC-F in the Chinese people. Two hundred thirty Chinese people over 65 years old were assessed by the SARC-F scale, PSMS, Lawton IADL and the shortened version of the falls efficacy scale-international (the short FES-I). Hospitalization was investigated. Physical performance and strength were measured. The association of SARC-F with other scales or tests was analyzed. Poor physical performance and grip strength were associated with SARC-F ≥ 4 independently (P<0.005). The value for agreement of SARC-F ≥ 4 and cutoff points of tests were 0.391 to 0.635. The short FES-I were correlated to SARC-F scores (Spearman's coefficient 0.692). Poor PSMS and Lawton IADL scores were associated with SARC-F ≥ 4(P=0.000) and SARC-F ≥ 4 was associated with hospitalization in the past 2 years (P=0.000). The SARC-F scale can identify old Chinese people with impaired physical function who may suffered from sarcopenia. SARC-F judgment reflects fear of falling, indicates the hospitalization events and is associated with ability of daily life. Thus, SARC-F may be a simple and useful tool for screening individuals with impaired physical function. Further studies on SARC-F in Chinese people would be worthy.
