RESUMO
BACKGROUND & AIMS: The association between sarcopenia and malnutrition has been poorly studied in the older population. The purpose of this study is to address the association between sarcopenia, according to different validated definitions, and nutritional status in a large population of community-dwelling older adults. METHODS: Observational, cross-sectional study of the Geriatric Frailty Clinic (GFC) for Assessment of Frailty and Prevention of Disability, held by the "Gérontopôle" of the Toulouse University Hospital. Patients aged above 65 years who benefitted from a Dual X-ray Densitometry (DXA) during their assessment at the GFC from June 5th 2013 to January 28th 2020 were included. Sarcopenia was defined according to proposed validated definitions. The Mini Nutritional Assessment (MNA) was used to stratify nutritional status, and identify patients with a poor nutritional status (at risk of malnutrition or malnourished, MNA <24). Multiple logistic regression analyses were performed between MNA and each sarcopenia definition adjusted for confounders. RESULTS: Among the 938 patients with DXA data, a total of 809 (86.2 %) subjects were included in the analysis (mean age 81.8 ± 6.9 years, 527 females (65.1 %)). Prevalence of sarcopenia ranged from 12.6 % to 44.9 %, according to various definitions. Overall 244 (30.2 %) of the patients had a poor nutritional status (MNA-score <24), Baumgartner and Newman definitions of sarcopenia were both associated with low MNA-scores (OR = 4.69, CI 3.15-6.98 and OR = 2.30, CI 1.55-3.14, respectively), EWGSOP2 "confirmed sarcopenia" definition was also associated with low MNA-scores (OR = 3.68, CI 2.30-5.89), as well as for the lean mass definition according EWGSOP2 cut-off (OR 5.22 CI 3.52-7.73). Both FNIH and EWGSOP2 "probable sarcopenia" definitions were not associated with the risk of malnutrition. CONCLUSIONS: In this study, the prevalence of sarcopenia ranged from 12.6 to 44.9 % according to various definitions. A score of MNA under 24, was associated with almost all of the sarcopenia definitions. This study reinforces the concept that malnutrition and sarcopenia are strictly related. When facing malnutrition in daily clinical practice, body composition should be assessed and the proposed nutritional intervention should be tailored by these results in order to prevent the onset of late-life disability.

Amiodarone therapy is widely prescribed in patients with atrial fibrillation. The higher prevalence of this arrhythmic heart disease, and the specific age-related issues of homeostasis in the elderly population, makes this group particularly exposed to its adverse effects. Among the many described side-effects, neurological impairments are the less documented and studied. Because amiodarone can be responsible for severe complications, as described in the case below, a close monitoring is necessary throughout its prescription. Awareness should be brought on the amiodarone-induced neurological side-effects as they could be overlooked.

OBJECTIVES: To examine frailty determinants differences in patients with a recent diagnosis of cancer compared to non-cancer patients among older adult. Revealing those differences will allow us to individualize the exact frailty management in those patients diagnosed with cancer. DESIGN: This is an observational cross-sectional, monocentric study. SETTING: Patients were evaluated at the Geriatric Frailty Clinic (GFC), in the Toulouse University Hospital, France, between October 2011 and February 2016. PARTICIPANTS: 1996 patients aged 65 and older were included (1578 patients without cancer and 418 patients with solid and hematological cancer recently diagnosed). MEASUREMENTS: Frailty was established according to the frailty phenotype. The frailty phenotype measures five components of frailty: weight loss, exhaustion, low physical activity, weakness and slow gait. Frailty phenotype was categorized as robust, pre-frail and frail. RESULTS: In a multinomial logistic regression, cancer, compared to the non-cancer group, is not associated with an increased likelihood of being classified as pre frail (RRR 0.9, 95% CI [0.5 ; 1.6 ], p 0.9) or frail (RRR 1.2, 95% CI [0.7 ; 2.0], p 0.4) rather than robust. When considering each Fried criterion, a significant higher odd of weight loss was observed in older patients with cancer compared to the non-cancer patients (OR 2.3, 95% CI [1.8; 3.0], p <0.001) but no statistically significant differences was found among the four other Fried criteria. Sensitivity analysis on the frailty index showed that cancer was not associated with a higher FI score compared to non-cancer (ß 0.002, 95%CI [-0.009; 0.01], p 0.6). CONCLUSION: In this real-life study evaluating elderly patients with and without cancer, we didn't confirm our hypothesis, in fact we found that cancer was not associated with frailty severity using both a phenotypic model and a deficit accumulation approach. Cancer may contribute, at least additively, to the development of frailty, like any other comorbidity, rather than a global underlying condition of vulnerability.

The proportion of adults over 60 years of age is rapidly increasing and is estimated to reach approximately one-sixth of the global population by 2030. An ageing population is a real challenge for healthcare resources, including dermatologists and geriatricians, as age-related changes in skin integrity and barrier function make older adults more susceptible to developing skin pathologies such as pruritus, dermatitis and infections. Fragile skin arises from several interlinked causes, including age-related changes in skin barrier integrity, previous and current lifestyle choices, skin pathologies and medical interventions. Dermo-cosmetics can play a key role in enhancing skin care regimens and preventing pathologies in this age group. In vitro studies, clinical, and in-daily clinical practice studies of dermo-cosmetics have shown them to be effective in many skin conditions in older adults, like xerosis and pruritus. Incontinence-associated dermatitis (IAD), a common condition arising from contact with irritants such as urine and faeces which can significantly impact the quality of life of sufferers, can also be improved with a barrier cream in incontinent patients aged 70 years and older. This supplement focuses on the increased fragility of older skin, the development of common skin pathologies and the efficacy and tolerance of dermo-cosmetic products in older adults.

INTRODUCTION: The phenotype proposed by Fried and colleagues is a widely used operational definition of frailty defining such state of extreme vulnerability of older persons. Low serum 25-hydroxy-vitamin D (25(OH)D) has been suggested as biomarker of frailty in literature. STUDY DESIGN: Cross-sectional. OBJECTIVES: To explore the association of 25(OH)D concentrations with the frailty phenotype and its criteria. METHODS: 321 subjects referred by their general practitioner to a geriatric frailty clinic were assessed between January 1, 2013 and September 23, 2013. Adjusted logistic regression models were performed between serum concentrations of 25(OH)D and the frailty phenotype (global score as well as its specific criteria). Receivers operating curves were established in order to explore the existence of a possible threshold of vitamin D levels highly predictive of frailty. RESULTS: Two hundred forty-one (75%) participants had 25(OH)D levels lower than 22 ng/ml. No significant association was reported between 25(OH)D levels and frailty. Among the five criteria of frailty, 25(OH)D was only associated with sedentariness (odds ratio 0.97 [95% confidence interval 0.95-0.99]). CONCLUSION: In our sample, no association was found between 25(OH)D levels and phenotype of frailty or the different frailty criterion except for sedentariness.

OBJECTIVES: To evaluate visual performance and factors associated with abnormal vision in patients screened for frailty at the Geriatric Frailty Clinic (GFC) for Assessment of Frailty and Prevention of Disability at Toulouse University Hospital. DESIGN: Retrospective, observational cross-sectional, single-centre study. SETTING: Institutional practice. PARTICIPANTS: Patients were screened for frailty during a single-day hospital stay between October 2011 and October 2014 (n = 1648). MEASUREMENTS: Collected medical records included sociodemographic data (including living environment and educational level), anthropometric data, and clinical data. The general evaluation included the patient's functional status using the Activities of Daily Living (ADL) scale and the Instrumental Activity of Daily Living (IADL) scale, the Mini-Mental State Examination (MMSE) for cognition testing, and the Short Physical Performance Battery (SPPB) for physical performance. We also examined Body Mass Index (BMI), the Mini-Nutritional Assessment (MNA), and the Hearing Handicap Inventory for the Elderly Screening (HHIE-S) tool. The ophthalmologic evaluation included assessing visual acuity using the Snellen decimal chart for distant vision, and the Parinaud chart for near vision. Patients were divided into groups based on normal distant/near vision (NDV and NNV groups) and abnormal distant/near vision (ADV and ANV groups). Abnormal distant or near vision was defined as visual acuity inferior to 20/40 or superior to a Parinaud score of 2, in at least one eye. Associations with frailty-associated factors were evaluated in both groups. RESULTS: The mean age of the population was 82.6 ± 6.2 years. The gender distribution was 1,061 females (64.4%) and 587 males (35.6%). According to the Fried criteria, 619 patients (41.1%) were pre-frail and 771 (51.1%) were frail. Distant and near vision data were available for 1425 and 1426 patients, respectively. Distant vision was abnormal for 437 patients (30.7%). Near vision was abnormal for 199 patients (14%). Multiple regression analysis showed that abnormal distant vision as well as abnormal near vision were independently associated with greater age (P < 0.01), lower educational level (P < 0.05), lower performance on the MMSE (P < 0.001), and lower autonomy (P < 0.02), after controlling for age, gender, educational level, Fried criteria, and MMSE score. CONCLUSION: The high prevalence of visual disorders observed in the study population and their association with lower autonomy and cognitive impairment emphasises the need for systematic screening of visual impairments in the elderly. Frailty was not found to be independently associated with abnormal vision.

BACKGROUND: The estimation of the risk of poor tolerance and overdose of antineoplastic agents protocols represents a major challenge in oncology, particularly in older patients. We hypothesize that age-related modifications of body composition (i.e. increased fat mass and decreased lean mass) may significantly affect tolerance to chemotherapy. METHOD: We conducted a systematic review for the last 25 years (between 1990 and 2015), using US National library of Medicine Medline electronic bibliographic database and Embase database of cohorts or clinical trials exploring (i) the interactions of body composition (assessed by Dual X-ray Absorptiometry, Bioelectrical Impedance Analyses, or Computerized Tomography) with pharmacokinetics parameters, (ii) the tolerance to chemotherapy, and (iii) the consequences of chemotherapies or targeted therapies on body composition. RESULTS: Our search identified 1504 articles. After a selection (using pre-established criteria) on titles and abstract, 24 original articles were selected with 3 domains of interest: impact of body composition on pharmacokinetics (7 articles), relationship between body composition and chemotoxicity (14 articles), and effect of anti-cancer chemotherapy on body composition (11 articles). The selected studies suggested that pharmacokinetic was influenced by lean mass, that lower lean mass could be correlated with toxicity, and that sarcopenic patients experienced more toxicities that non-sarcopenic patients. Regarding fat mass, results were less conclusive. No studies specifically explored the topic of body composition in older cancer patients. CONCLUSIONS: Plausible pathophysiological pathways linking body composition, toxicity, and pharmacokinetics are sustained by the actual review. However, despite the growing number of older cancer patients, our review highlighted the lack of specific studies in the field of anti-neoplastic agents toxicity regarding body composition conducted in elderly.

INTRODUCTION: Frailty is considered as an early stage of disability which, differently from disability, is still amenable for preventive interventions and is reversible. In 2011, the "Geriatric Frailty Clinic (G.F.C) for Assessment of Frailty and Prevention of Disability" was created in Toulouse, France, in association with the University Department of General Medicine and the Midi-Pyrénées Regional Health Authority. This structure aims to support the comprehensive and multidisciplinary assessment of frail older persons, to identify the specific causes of frailty and to design a personalized preventive plan of intervention against disability. In the present paper, we describe the G.F.C structure, organization, details of the global evaluation and preventive interventions against disability, and provide the main characteristics of the first 1,108 patients evaluated during the first two years of operation. METHODS: Persons aged 65 years and older, considered as frail by their physician (general practitioner, geriatrician or specialist) in the Toulouse area, are invited to undergo a multidisciplinary evaluation at the G.F.C. Here, the individual is assessed in order to detect the potential causes for frailty and/or disability. At the end of the comprehensive evaluation, the team members propose to the patient (in agreement with the general practitioner) a Personalized Prevention Plan (PPP) specifically tailored to his/her needs and resources. The G.F.C also provides the patient's follow-up in close connection with family physicians. RESULTS: Mean age of our population was 82.9 ± 6.1 years. Most patients were women (n=686, 61.9%). According to the Fried criteria, 423 patients (39.1%) were pre-frail, and 590 (54.5%) frail. Mean ADL (Activities of Daily Living) score was 5.5 ± 1.0. Consistently, IADL (Instrumental ADL) showed a mean score of 5.6 ± 2.4. The mean gait speed was 0.78 ± 0.27 and 25.6% (272) of patients had a SPPB (Short Physical Performance Battery) score equal to or higher than 10. Dementia was observed in 14.9% (111) of the G.F.C population according to the CDR scale (CDR ≥2). Eight percent (84) presented an objective state of protein-energy malnutrition with MNA (Mini Nutritional Assessment) score < 17 and 39.5% (414) were at risk of malnutrition (MNA=17-23.5). Concerning PPP, for 54.6% (603) of patients, we found at least one medical condition which needed a new intervention and for 32.8% (362) substantial therapeutic changes were recommended. A nutritional intervention was proposed for 61.8% (683) of patients, a physical activity intervention for 56.7% (624) and a social intervention for 25.7% (284). At the time of analysis, a one-year reassessment had been carried out for 139 (26.7%) of patients. CONCLUSIONS: The G.F.C was developed to move geriatric medicine to frailty, an earlier stage of disability still reversible. Its particularity is that it is intended for a single target population that really needs preventive measures: the frail elderly screened by physicians. The screening undergone by physicians was really effective because 93.6% of the subjects who referred to this structure were frail or pre-frail according to Fried's classification and needed different medical interventions. The creation of units like the G.F.C, specialized in evaluation, management and prevention of disability in frail population, could be an interesting option to support general practitioners, promote the quality of life of older people and increase life expectancy without disability.

An international task force of academic and industry leaders in sarcopenia research met on December 5, 2012 in Orlando, Florida to develop guidelines for designing and executing randomized clinical trials of sarcopenia treatments. The Task Force reviewed results from previous trials in related disease areas to extract lessons relevant to future sarcopenia trials, including practical issues regarding the design and conduct of trials in elderly populations, the definition of appropriate target populations, and the selection of screening tools, outcome measures, and biomarkers. They discussed regulatory issues, the challenges posed by trials of different types of interventions, and the need for standardization and harmonization. The Task Force concluded with recommendations for advancing the field toward better clinical trials.

The frailty syndrome is a pre-disability condition suitable to be targeted by preventive interventions against disability. In order to identify frail older persons at risk of negative outcomes, general practitioners must be provided with an easy and quick screening tool for detecting frailty without special effort. In the present paper, we present the screening tool for frailty that the Gérontopôle of Toulouse (France) has developed and implemented in primary care in the region with the collaboration of the Department of Family Medicine of the University of Toulouse. The Gérontopôle Frailty Screening Tool (GFST) is designed to be administered to persons aged ≥65 years with no physical disability and acute clinical disease. It is composed by an initial questionnaire aimed at attracting the general practitioner's attention to very general signs and/or symptoms suggesting the presence of an underlying frailty status. Then, in a second section, the general practitioner expresses his/her own view about the frailty status of the individual. The clinical judgment of the general practitioner is finally retained for determining the eventual presence of frailty. Preliminary data document that almost everyone (95.2%) of the 442 patients referred to the Gérontopôle frailty clinic by general practitioners using the GFST indeed presents a condition of (pre-)frailty according to the criteria proposed by Fried and colleagues in the Cardiovascular Health Study. The use of the GFST may help at raising awareness about the importance of identifying frailty, training healthcare professionals at the detection of the syndrome, and developing preventive interventions against disabling conditions.

BACKGROUND: The prevalence of vitamin D insufficiency is very high in the nursing home (NH) population. Paradoxically, vitamin D insufficiency is rarely treated despite of strong clinical evidence and recommendations for supplementation. This review aims at reporting the current knowledge of vitamin D supplementation in NH and proposing recommendations adapted to the specificities of this institutional setting. DESIGN: Current literature on vitamin D supplementation for NH residents was narratively presented and discussed by the French Group of Geriatrics and Nutrition. RESULT: Vitamin D supplementation is a safe and well-tolerated treatment. Most residents in NH have vitamin D insufficiency, and would benefit from vitamin D supplement. However, only few residents are actually treated. Current specific and personalized protocols for vitamin D supplementation may not be practical for use in NH settings (e.g., assessment of serum vitamin D concentrations before and after supplementation). Therefore, our group proposes a model of intervention based on the systematic supplementation of vitamin D (1,000 IU/day) since the patient's admission to the NH and throughout his/her stay without the need of a preliminary evaluation of the baseline levels. Calcium should be prescribed only in case of poor dietary calcium intake. CONCLUSION: A population-based rather than individual-based approach may probably improve the management of vitamin D insufficiency in the older population living in NH, without increasing the risks of adverse health problems. The clinical relevance and cost effectiveness of this proposal should be assessed under NH real-world conditions to establish its feasibility.

An operational definition of musculoskeletal decline in older people is needed to allow development of interventions for prevention or treatment, as was developed for the treatment of osteoporosis. Frailty and sarcopenia are linked, but distinct, correlates of musculoskeletal aging that have many causes, including age-related changes in body composition, inflammation, and hormonal imbalance. With the emergence of a number of exciting candidate therapies to retard the loss of muscle mass with aging, the derivation of a consensual definition of sarcopenia and physical frailty becomes an urgent priority. Although several consensual definitions have been proposed, these require clinical validation. An operational definition, which might provide a threshold for treatment/trial inclusion, should incorporate a loss of muscle mass as well as evidence of a decrease in muscle strength and/or physical activity. Evidence is required for a link between improvements in the measures of muscle strength and/or physical activity and clinical outcomes to allow development of interventions to improve clinical outcomes in frail older patients.

OBJECTIVE: To determine whether there was an association between the Five-Times-Sit-to-Stand test (FTSS) and the global cognitive function assessed with Short-Portable-Mental-State-Questionnaire (SPMSQ) among the EPIDOS cohort. DESIGN: Cross-sectional study corresponding to the baseline assessment of the EPIDOS study. SETTING: Five French cities including Amiens, Lyon, Montpellier, Paris and Toulouse. PARTICIPANTS: 7421 community-dwelling older women (mean age 80.41 ± 0.04 years). MEASUREMENTS: Time to achieve FTSS, and SPMSQ score. Age, body mass index, high number of comorbidities, cardiovascular risk factors, depression, regular physical activity, joint pain, quadriceps strength, visual acuity, use of psychoactive drugs, serum albumin, vitamin D deficiency (i.e., serum concentration < 10 ng/mL), and the influence of seasons and study centers were used as covariables. Subjects were divided into 2 groups according to SPMSQ score (either impaired < 8/10 or normal ≥ 8/10). RESULTS: Compared to their counterparts, the women with cognitive impairment (n=1190, mean 81.51 ± 0.45 years) took more time in performing FTSS (17.8± 0.9 seconds versus 16.1 ± 0.3 seconds, P < 0.001). There was a significant negative association of SPMSQ score with FTSS (Unadjusted ß=-0.02(95%CI -0.03;-0.01), P< 0.001; Fully Adjusted ß=-0.03(95%CI -0.05;-0.01), P=0.003; Stepwise Backward Adjusted ß=-0.02(95%CI -0.04;-0.01), P=0.005), as well as with advance in age (ß=-0.04, P=0.006) and vitamin D deficiency (ß=-0.34, P=0.011). The FTSS limit value in predicting moderate cognitive impairment was set at 15 seconds by a sensitivity analysis (negative predictive value=86%). CONCLUSION: We found a negative association of FTSS with global cognitive performance. Achieving FTSS in less than 15 seconds made unlikely the existence of a moderate cognitive impairment. FTSS could be used as a tool in primary care medicine to exclude moderate cognitive decline.

INTRODUCTION: The use of a simple, safe, and easy to perform assessment tool, like gait speed, to evaluate vulnerability to adverse outcomes in community-dwelling older people is appealing, but its predictive capacity is still questioned. The present manuscript summarises the conclusions of an expert panel in the domain of physical performance measures and frailty in older people, who reviewed and discussed the existing literature in a 2-day meeting held in Toulouse, France on March 12-13, 2009. The aim of the IANA Task Force was to state if, in the light of actual scientific evidence, gait speed assessed at usual pace had the capacity to identify community-dwelling older people at risk of adverse outcomes, and if gait speed could be used as a single-item tool instead of more comprehensive but more time-consuming assessment instruments. METHODS: A systematic review of literature was performed prior to the meeting (Medline search and additional pearling of reference lists and key-articles supplied by Task Force members). Manuscripts were retained for the present revision only when a high level of evidence was present following 4 pre-selected criteria: a) gait speed, at usual pace, had to be specifically assessed as a single-item tool, b) gait speed should be measured over a short distance, c) at baseline, participants had to be autonomous, community-dwelling older people, and d) the evaluation of onset of adverse outcomes (i.e. disability, cognitive impairment, institutionalisation, falls, and/or mortality) had to be assessed longitudinally over time. Based on the prior criteria, a final selection of 27 articles was used for the present manuscript. RESULTS: Gait speed at usual pace was found to be a consistent risk factor for disability, cognitive impairment, institutionalisation, falls, and/or mortality. In predicting these adverse outcomes over time, gait speed was at least as sensible as composite tools. CONCLUSIONS: Although more specific surveys needs to be performed, there is sufficient evidence to state that gait speed identifies autonomous community-dwelling older people at risk of adverse outcomes and can be used as a single-item assessment tool. The assessment at usual pace over 4 meters was the most often used method in literature and might represent a quick, safe, inexpensive and highly reliable instrument to be implemented.

INTRODUCTION: To date, very little research has been carried out in nursing homes and it is difficult to make recommendations for quality of care that are based on actual data. The Réseau de Recherche en Etablissement d'Hébergement pour Personnes Agées (REHPA) is a functional network established in collaboration between the geriatric department of Toulouse University Hospital and 240 nursing homes with the aim of compensating for the lack of evidence-based recommendations and of enhancing research. MATERIALS AND METHODS: A cross-sectional observational study was conducted between January and March 2008. The number of residents included (randomly selected by birth date) depended on the total number of residents of the facility. Demography, medical and drug history, disabilities and care practices were assessed by geriatrician. RESULTS: We report the findings in 4896 residents of 240 nursing homes. Residents were 73.9% women, mean age 85.7 +/- 8.8 years, mean weight 61.9 +/- 14.8 kg, with a mean ADL score of 2.8 +/- 2.1. Dementia was diagnosed in 43.5% (of whom only 50.9% were treated), 19.6% showed aggressive behaviours, 10.8% exhibited disruptive vocalization and 10.9% were wanderers, 27.4% were treated with antipsychotic medications, 54.4% had hypertension, 8.7% had diabetes, 14.8% were osteoporotic, 4.1% had fallen during the previous week, 37.9% were in pain and 19.8% had lost weight. The mean Charlson index score was 1.6 +/- 1.4. Finally, 13.5% had been admitted to hospital within the previous three months. CONCLUSION: The survey identifies specific issues in order to target future research in the nursing home setting.

Sarcopenia is an evolving concept and the current definition of sarcopenia includes both a loss of muscle strength and loss of muscle mass. However, despite the increasing knowledge and improved technology, a worldwide operational definition of sarcopenia applicable across racial/ethnic groups and populations lacks consensus. As a result the prevalence of sarcopenia (8 to 40% of older people over 60 years) varies depending on the study sample (namely the age of the sample), the definition, and the assessment tool used. DXA is the main assessment method used to evaluate muscle mass, which is further adjusted to height, weight fat mass, or BMI to obtain an index of sarcopenia. Cross-sectional analyses seemed to prove an association between low muscle mass and functional decline, but these results were not consistent when analysed longitudinally over time. This inconsistency could be due to methodological issues as the selected populations in the cohorts where autonomous, community-dwelling, older people. In this highly active population decreases in muscle mass might be not as important as decreases in strength to predict functional decline. The aim of the present paper was to perform a comprehensive review of the literature on the epidemiology of sarcopenia and its consequences to be presented on November 13th and 14th 2008, at the Carla Workshop.

In the presence of an aging population, public health priorities need to evolve. As the populations gets older, the already existing pathologies have become commonplace with specific geriatric clinical syndromes like frailty, mobility disability, or cognitive impairment, among others. Sarcopenia is a good example for which geriatricians, neurologists, physiologists, nutritionists and epidemiologists need to find a consensual definition and diagnostic tool as well as guidelines for the management of clinical trials and possible treatments. The Carla Sarcopenia Task Force, which met in the south of France (Toulouse) for an expert consensus meeting called "Les Entretiens du Carla", have addressed a series of existing issues to place Sarcopenia into a nosological context: a definition which should be a composite of a change in muscle mass and a change in strength/function depending on either a progressive and chronic wasting process or an acute onset of loss of muscle mass; a recommendation for DXA and the Short Physical Performance Battery as a clinical pragmatic approach of Sarcopenia; a differentiated approach for clinical studies according to prevention or treatment objectives and depending on the sub-groups and target populations; and finally, a summary of therapeutic strategies currently recommended. The aim of "Les Entretiens du Carla", based on an expert meeting panel, was to address a series of unsolved issues in the field of Sarcopenia by combining the expert opinion with a revision of the existing literature on the topic. Through this report, the reader will appreciate the determination to find conclusions on the various issues and further studies to be developed to determine the best multidisciplinary approach needed.
