RESUMEN

The decrease of physical abilities and functional decline that can be caused by musculoskeletal conditions such as sarcopenia, can lead to higher levels of dependency and disability. Therefore, it may influence patient reported outcome measures (PROM), such as the health-related quality of life (HRQoL). The purpose of this systematic review and meta-analysis is to provide a comprehensive overview of the relationship between sarcopenia and HRQoL. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were followed throughout the whole process of this work. A protocol was previously published on PROSPERO. The electronic databases MEDLINE, Scopus, Allied and Complementary Medicine (AMED), EMB Review - ACP Journal Club, EBM Review - Cochrane Central of Register of Controlled Trials and APA PsychInfo were searched until October 2022 for observational studies reporting a HRQoL assessment in both sarcopenic and non-sarcopenic individuals. Study selection and data extraction were carried out by two independent researchers. Meta-analysis was performed using a random effect model, reporting an overall standardized mean difference (SMD) and its 95% confidence interval (CI) between sarcopenic and non-sarcopenic individuals. Study quality was measured using the Newcastle-Ottawa Scale and the strength of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. The search strategy identified 3725 references from which 43 observational studies were eligible and included in this meta-synthesis study. A significantly lower HRQoL was observed for sarcopenic individuals compared with non-sarcopenic ones (SMD -0.76; 95% CI -0.95; -0.57). Significant heterogeneity was associated with the model (I2  = 93%, Q test P-value <0.01). Subgroup analysis showed a higher effect size when using the specific questionnaire SarQoL compared with generic questionnaires (SMD -1.09; 95% CI -1.44; -0.74 with the SarQoL versus -0.49; 95% CI -0.63; -0.36 with generic tools; P-value for interaction <0.01). A greater difference of HRQoL between sarcopenic and non-sarcopenic was found for individuals residing in care homes compared with community-dwelling individuals (P-value for interaction <0.001). No differences were found between age groups, diagnostic techniques, and continents/regions. The level of evidence was rated as moderate using the GRADE assessment. This systematic review and meta-analysis combining 43 observational studies shows that HRQoL is significantly reduced in sarcopenic patients. The use of disease-specific HRQoL instruments may better discriminate sarcopenic patients with respect to their quality of life.

RESUMEN

The risk of falls associated with population ageing and the burden of chronic diseases increase the risk of fragility fractures. Globally, a large increase in the numbers of people sustaining fragility fractures is predicted. The management of highly vulnerable older persons who present and/or are at risk of fragility fractures is challenging given their clinical complexity and the fragmentation of the healthcare services. Fragility fractures frequently result in reduced functional ability and quality of life. Therefore, it is essential to implement person-centered models of care to address the individual's priorities and needs. In this context, the multidimensional construct of intrinsic capacity, composed of the critical functions on which the individual's functional ability rely, becomes of particular interest.In this article, the potential of current models to meet the global challenge is considered, particularly where healthcare systems are less integrated and poorly structured. It then describes how assessment of intrinsic capacity might provide the clinician with a holistic picture of an older individual's reserves before and after a fragility fracture and the implications of implementing this approach based on the construct of intrinsic capacity in healthcare systems, in both well-developed and low-resourced settings. It suggests that optimization of intrinsic capacity and functional ability is a credible conceptual model and might support a generally feasible approach to primary and secondary fracture prevention in older people.

RESUMEN

Frailty is a clinical syndrome characterized by a reduced physiologic reserve, increased vulnerability to stressors and an increased risk of adverse outcomes. People with atrial fibrillation (AF) are often burdened by frailty due to biological, clinical, and social factors. The prevalence of frailty, its management and association with major outcomes in AF patients are still not well quantified. We systematically searched PubMed and EMBASE, from inception to September 13th, 2021, for studies reporting the prevalence of frailty in AF patients. The study was registered in PROSPERO (CRD42021235854). 33 studies were included in the systematic review (n = 1,187,651 patients). The frailty pooled prevalence was 39.7 % (95 %CI=29.9 %-50.5 %, I2 =100 %), while meta-regression analyses showed it is influenced by age, history of stroke, and geographical location. Meta-regression analyses showed that OAC prescription was influenced by study-level mean age, baseline thromboembolic risk, and study setting. Frail AF patients were associated with a higher risk of all-cause death (OR=5.56, 95 %CI=3.46-8.94), ischemic stroke (OR=1.59, 95 %CI=1.00-2.52), and bleeding (OR=1.64, 95 %CI=1.11-2.41), when compared to robust individuals. In this systematic review and meta-analysis, the prevalence of frailty was high in patients with AF. Frailty may influence the prognosis and management of AF patients, thus requiring person-tailored interventions in a holistic or integrated approach to AF care.

RESUMEN

Background: While efforts have been made to validate intrinsic capacity (IC) as a multidimensional indicator of healthy aging in high-income countries, we still need evidence from lower-income countries. We examined associations of IC with wide ranges of activities of daily living in a nationally representative sample of Brazilians aged≥50 years. Methods: This cross-sectional analysis included 7175 participants from the Brazilian Longitudinal Study of Aging. IC domains (cognitive, psychological, sensory, locomotor, and vitality) were determined using self-reported and physical performance measures. IC was operationalized through factorial analysis. We investigated associations of IC and its domains with functional ability in basic, instrumental, and advanced activities of daily living (ADL, IADL, and AADL) using logistic regressions adjusted for sociodemographic, clinical, and modifiable risk factors. Findings: The IC bi-factorial model revealed satisfactory goodness-of-fit. Preserved ability in ADL and IADL, respectively, ranged from 69% and 29% to 89% and 74% across IC quartiles. In adjusted analyses, every standard deviation increment in IC composite score was associated with almost twice the odds of preserved ADL (OR=1·72; 95%CI=1·54-1·93), preserved IADL (OR=1·95; 95%CI=1·77-2·16), and high performance in AADL (OR=1·79; 95%CI=1·59-2·00). Similar results were reported using the IC domains as predictors. Although age, race/ethnicity, and education did not modify associations of IC with functional ability, we found sex differences with stronger relationships of IC with preserved ADL or IADL in females. Interpretation: Our results support IC validity and reliability to measure healthy aging in diverse socioeconomic and cultural settings. Incorporating IC in routine practices can promote holistic and person-centered care approaches in aging societies. Funding: The Brazilian Ministry of Health and Ministry of Science, Technology, Innovation, and Communication.

RESUMEN

Aging is characterized by increase in reactive oxygen (ROS) and nitrogen (RNS) species, key factors of cardiac failure and disuse-induced muscle atrophy. This study focused on serum nitroproteome as a trait of longevity by adopting two complementary gel-based techniques: two-dimensional differential in gel electrophoresis (2-D DIGE) and Nitro-DIGE coupled with mass spectrometry of albumin-depleted serum of aged (A, n = 15) and centenarian (C, n = 15) versus young females (Y, n = 15). Results indicate spots differently expressed in A and C compared to Y and spots changed in A vs. C. Nitro-DIGE revealed nitrosated protein spots in A and C compared to Y and spots changed in A vs. C only (p-value < 0.01). Nitro-proteoforms of alpha-1-antitripsin (SERPINA1), alpha-1-antichimotripsin (SERPINA3), ceruloplasmin (CP), 13 proteoforms of haptoglobin (HP), and inactive glycosyltransferase 25 family member 3 (CERCAM) increased in A vs. Y and C. Conversely, nitrosation levels decreased in C vs. Y and A, for immunoglobulin light chain 1 (IGLC1), serotransferrin (TF), transthyretin (TTR), and vitamin D-binding protein (VDBP). Immunoblottings of alcohol dehydrogenase 5/S-nitrosoglutathione reductase (ADH5/GSNOR) and thioredoxin reductase 1 (TRXR1) indicated lower levels of ADH5 in A vs. Y and C, whereas TRXR1 decreased in A and C in comparison to Y. In conclusion, the study identified putative markers in C of healthy aging and high levels of ADH5/GSNOR that can sustain the denitrosylase activity, promoting longevity.

RESUMEN

The "male-female health-survival paradox" evidences that the survival advantage observed in women is linked to higher rates of disability and poor health status compared to men, a phenomenon also called the "sex-frailty paradox". The depletion of vitamin D seems to play a role in the fragilization of old persons, and genetic polymorphisms of the vitamin D receptor (VDR) gene seem to be involved in regulating the vitamin D pathway. This study correlated the VDR gene polymorphisms (FokI, ApaI, BsmiI, and TaqI) with frailty, computed by frailty index (FI), in 202 persons (127 women and 75 men, aged from 60 to 116 years), aiming to capture the involvement of vitamin D in the sex-frailty paradox. The results showed slightly higher FI (p = 0.05), lower levels of 25(OH)D (p = 0.04), and higher levels of parathyroid hormone PTH (p = 0.002) and phosphorus (p < 0.001) in women than in men. Interestingly, the ApaI minor allele (Aa + aa) showed a significant positive association with FI (p = 0.03) and a negative association with inorganic phosphorus values (p = 0.04) compared to AA genotype only in women, regardless of age. The exact mechanism and the causal role that, in old women, links ApaI polymorphism with frailty are still unclear. However, we could speculate that a specific genetic profiling, other than 25(OH)D levels, play a role in the sex-frailty paradox.

RESUMEN

BACKGROUND: Although there is growing utilisation of intermediate care to improve the health and well-being of older adults with complex care needs, there is no international agreement on how it is defined, limiting comparability between studies and reducing the ability to scale effective interventions. AIM: To identify and define the characteristics of intermediate care models. METHODS: A scoping review, a modified two-round electronic Delphi study involving 27 multi-professional experts from 13 countries, and a virtual consensus meeting were conducted. RESULTS: Sixty-six records were included in the scoping review, which identified four main themes: transitions, components, benefits and interchangeability. These formed the basis of the first round of the Delphi survey. After Round 2, 16 statements were agreed, refined and collapsed further. Consensus was established for 10 statements addressing the definitions, purpose, target populations, approach to care and organisation of intermediate care models. DISCUSSION: There was agreement that intermediate care represents time-limited services which ensure continuity and quality of care, promote recovery, restore independence and confidence at the interface between home and acute services, with transitional care representing a subset of intermediate care. Models are best delivered by an interdisciplinary team within an integrated health and social care system where a single contact point optimises service access, communication and coordination. CONCLUSIONS: This study identified key defining features of intermediate care to improve understanding and to support comparisons between models and studies evaluating them. More research is required to develop operational definitions for use in different healthcare systems.

RESUMEN

The use of biomarkers is profoundly transforming medical research and practice. Their adoption has triggered major advancements in the field of Alzheimer's disease (AD) over the past years. For instance, the analysis of the cerebrospinal fluid (CSF) and neuroimaging changes indicative of neuronal loss and amyloid deposition has led to the understanding that AD is characterized by a long preclinical phase. It is also supporting the transition towards a biology-grounded framework and definition of the disease. Nevertheless, though sufficient evidence exists about the analytical validity (i.e., accuracy, reliability, and reproducibility) of the candidate AD biomarkers, their clinical validity (i.e., how well the test measures the clinical features, and the disease or treatment outcomes) and clinical utility (i.e., if and how the test improves the patient's outcomes, confirms/changes the diagnosis, identifies at-risk individuals, influences therapeutic choices) have not been fully proven. In the present review, some of the methodological issues and challenges that should be addressed in order to better appreciate the potential benefits and limitations of AD biomarkers are discussed. The ultimate goal is to stimulate a constructive discussion aimed at filling the existing gaps and more precisely defining the directions of future research. Specifically, four main aspects of the clinical validation process are addressed and applied to the most relevant CSF biomarkers: (1) the definition of reference values; (2) the identification of reference standards for the disease of interest (i.e., AD); (3) the inclusion within the diagnostic process; and (4) the statistical process supporting the whole framework.

RESUMEN

Vitamin D is a secosteroid hormone that exerts a pleiotropic action on a wide spectrum of tissues, apparatuses and systems. Thus, vitamin D has assumed an increasingly dominant role as a key determinant of biological mechanisms and specific clinical conditions. Older people frequently present vitamin D deficiency, a status potentially influencing several mechanisms responsible for different age-related diseases. Centenarians symbolize the ideal model for investigating the peculiar traits of longevity, as they have reached an age close to the estimated limit of the human lifespan. Interestingly, despite the profound heterogeneity of centenarians in terms of health status, all these people share the same condition of severe vitamin D deficiency, suggesting that they may have implemented a number of adaptive strategies to cope with the age-related physiological derangement of vitamin D metabolism. The lesson deriving from centenarians' experience suggests that: i) severe vitamin D deficiency does not preclude the possibility of reaching extreme longevity, ii) strategies to prevent hypovitaminosis D may be useful to slow down the processes of "fragilization" occurring in aged people, iii) beneficial effects of vitamin D supplementation need to be confirmed regarding longevity.

RESUMEN

OBJECTIVE: The purpose of this study was to investigate the effect of a session of osteopathic manipulative techniques on diaphragmatic motion and thickness in healthy participants. METHODS: This was a prospective, randomized, double-blinded, case vs sham vs control clinical trial performed in an outpatient osteopathic clinic in Rome, Italy. Sixty-seven healthy participants, mean age 40.4 ± 14.5 years, received an ultrasound evaluation of diaphragmatic motion and thickness, followed by a systematic osteopathic evaluation. After randomization, the experimental group (n = 22) received osteopathic manipulation, whereas the sham (n = 22) and the control (n = 22) groups had a light touch approach and simple observation, respectively. After a 1-session intervention, new osteopathic and ultrasound assessments were repeated in all participants. RESULTS: A statistically significant increase in diaphragmatic mobility was observed in the experimental group after the osteopathic manipulation (Δ = 14.5 mm, P < .001; analysis of variance P < .001 vs both sham: Δ = -0.22 mm, and control: Δ = -2.09 mm groups). A strong linear relationship was observed between the diaphragmatic motion gradient, measured with ultrasonography, and the score assigned by the operator evaluating the change of diaphragm mobility after intervention. CONCLUSION: Osteopathic techniques used in this study improved the diaphragmatic motion (but not the muscle thickness) in healthy participants. Further studies are needed to confirm our findings and eventually identify the clinical conditions that may benefit from osteopathic manipulative treatment of the diaphragm.

RESUMEN

BACKGROUND: Dozens of scales and questionnaires have been used in the detection of frailty; however, a generalized method for its screening and diagnosis is still lacking in clinical settings. FRAILTOOLS´ main objective is to evaluate the usefulness of frailty scales in the detection of frailty in different clinical and social settings, and its integration in management algorithms for the frail older patient. METHODS: FRAILTOOLS is an observational, longitudinal and prospective study with a follow-up of 6, 12 and 18 months. People older than 75 years old will be recruited from three separate clinical settings (acute geriatric wards, geriatric outpatient clinics and primary care) and one social setting (nursing homes). Exclusion criteria include Mini-mental State Examination < 20 points, and a Barthel index < 90 points, except in nursing home residents (< 40 points). The participants will be recruited in Spain, Italy, France, United Kingdom and Poland. The total sample size will be of 1.940 subjects, 97 subjects in each clinical setting by center. A personal interview with each participant will take place to register data on comorbidity (Charlson Index), functional (SPPB, Barthel and Lawton indexes), cognitive (MMSE) and frailty status (Fried Phenotype, Frailty Trait Scale - short version, SHARE-FI, 35-Items Rockwood Frailty Index, Clinical Frailty Scale, FRAIL scale and Gérontopôle Frailty Screening Tool) in the baseline visit, month 12 and month 18 visit of follow up. At 6 month a phone call will be made to assess whether there have been falls and to check the vital status. DISCUSSION: Currently, the usefulness of certain assessment tools in social and clinical settings have not been properly assessed, including their ability to predict the individual risk for different adverse outcomes, which is the main interest in daily practice. The FRAILTOOLS project concentrates on providing screening and diagnostic tools for frailty in those settings where its prevalence is the highest and where efforts in prevention could make a significant change in the trend towards disability. TRIAL REGISTRATION: Comprehensive validation of frailty assessment tools in older adults in different clinical and social settings (FRAILTOOLS), NCT02637518 (date of registration: 12/18/2015).

RESUMEN

BACKGROUND: Frailty is highly prevalent in older persons and associated with negative health-related events and costs. Despite successful clinical trials, translation of evidence into implementation of dedicated programs has been scarce. This is probably due to funding limitations and lack of generalizability of rigid schemes adopted in controlled studies. We propose a guidance to implement complex interventions against frailty in the community, and describe the design and early findings of the +AGIL Barcelona program. METHODS: A guidance "decalogue" resulted from an experts' panel prioritization of recommendations by international independent bodies. On this basis, we reorganized existing primary care, geriatrics and community-based resources to implement our program, which includes a screening, a multi-component intervention modulated on the comprehensive geriatric assessment and integrated follow-up plus continuity through community-based resources. The pre-post impact of the program on physical function, as well as on clinical endpoints, person-center outcomes and costs will be assessed. RESULTS: Integrated care, multi-component, person-centered strategies to empower the final users in a flexible and adaptable way should be promoted after raising awareness and potentially convey long term investments. In 22 months, 185 participants (mean age ±â€¯SD = 81.6 ±â€¯5.7 years, 72% women) joined the program. Although independent in the activities of daily living, participants showed clear indicators of frailty (Short Physical Performance Battery = 7.1 ±â€¯2.5; gait speed = 0.69 ±â€¯0.2 m/s). CONCLUSIONS: +AGIL Barcelona may represent a unique model to manage frailty in older community-dwellers, translating evidence into pragmatic clinical practice. Further research will clarify the effects of this intervention.

RESUMEN

Findings from recent Alzheimer's disease prevention trials have shown subjects with increased dementia score based upon mid-life cardiovascular risk factors, to benefit from multi-domain intervention strategies to some extent. The effects of such interventions on cognitive functions remains yet to be well-established. This study is a secondary analysis of the MAPT study, 1,293 older subjects (mean age 75 years) with high CAIDE score (i.e., ≥6) were classified according to the four intervention groups: 1) multi-domain intervention plus placebo, 2) isolated supplementation with Omega-3 polyunsaturated fatty acid (n-3 PUFA), 3) combination of the two interventions, and 4) placebo alone. Linear mixed-model repeated-measures analyses were used to assess the cognitive changes according to various neuropsychological test scores between intervention groups compared to the placebo at 36 months from baseline. Compared to the placebo, group with multi-domain intervention in combination withn-3PUFA was found to show significant improvement in the delayed total recall test of the free and cued selective reminding test (FCSRT) (mean±standard error(SE) = 0.20±0.10) and MMSE orientation test (mean±SE = 0.15±0.06) at 36 months. Isolated multi-domain intervention group showed significant less decline in the MMSE orientation test (mean±SE = 0.12±0.06) compared to the placebo. There was significant less improvement (mean±SE = - 1.01±0.46) in the FCSRT free recall test in the n-3 PUFA intervention group compared to the placebo at 36 months. Our findings show high-risk subjects for dementia screened with CAIDE dementia score might benefit from multi-domain intervention strategies as in the MAPT study, particularly in the orientation and delayed recall domain.

RESUMEN

According to the free-radical theory of aging, oxidative stress is a key contributor to the onset of age-related conditions by inducing structural and functional alterations in several cellular components. Although innate defenses exist for limiting the occurrence of such detrimental effects, their ability to counteract the continuous and large production of reactive oxygen species becomes increasingly inefficient with aging. In this context, interventions aimed at preserving the homeostatic balance between oxidant production and antioxidant protection may be beneficial on the pathophysiological modifications and clinical manifestations featuring the aging process. Sarcopenia is a clinical condition defined as the progressive age-related loss of muscle mass and function. In particular, a reduction of motor units and wasting of muscle fibers occurs during the aging process and negatively affects muscle quality. The biological mechanisms responsible for sarcopenia are complex, multifactorial and closely related to those characterizing the aging process. Among these, a pronounced unbalance between pro-oxidant and antioxidant species may play a major role. This review paper presents and discusses the possible role of the oxidant/antioxidant systems in the determination and development of the sarcopenic phenotype. Special attention will be devoted to the contribution of antioxidant agents in the maintenance of the homeostatic equilibrium for the organismal protection against the onset of age-related conditions. However, despite their popularity as beneficial compounds, there is no clear evidence in the literature about the protective effect of antioxidant supplements usage. Therefore, further research is needed to address and clarify such ambiguity.

RESUMEN

Background/objectives: to investigate the effects of a 3-year multidomain lifestyle intervention, omega-3 supplementation or both on physical activity (PA) in older adults with subjective memory complaints. Design/settings/subjects: the Multidomain Alzheimer Preventive Trial was a 3-year randomised controlled trial that enroled 1,680 community-dwelling adults aged 70 years or over, with subjective memory complaints. Participants were randomised to omega-3 supplementation (total daily dose of 800 mg docosahexanoic acid and up to 225 mg eicosapentanoic acid), multidomain intervention (nutritional and exercise counselling and cognitive training), omega-3 plus multidomain intervention or placebo with usual care. Methods: PA was assessed using a self-reported questionnaire. From this, global moderate-to-vigorous PA, leisure-time PA, non-leisure-time PA and light PA were measured in metabolic equivalent tasks-minutes per week (MET-min/week). Results: in the multidomain groups, participants significantly increased their moderate-to-vigorous and leisure-time PA at 6 months (≥300 MET-min/week for both in the multidomain groups; P ≤ 0.002) before returning to baseline by the end of the trial. Activity in the placebo/usual care and omega-3/usual care groups declined overtime. Between-group differences remained significant for both multidomain groups for leisure-time physical activity at 2- and 3-year follow-ups. Compared to placebo/usual care, interventions had no significant effects on non-leisure-time PA and light PA. Omega-3 supplementation alone had no effects on PA. Conclusions: a multidomain intervention focused on cognitive training, and nutritional and PA counselling increased PA in the short-term and limited its decline in the long-term among older adults with memory complaints.

RESUMEN

OBJECTIVE: To develop Clinical Practice Guidelines for the screening, assessment and management of the geriatric condition of frailty. METHODS: An adapted Grading of Recommendations, Assessment, Development, and Evaluation approach was used to develop the guidelines. This process involved detailed evaluation of the current scientific evidence paired with expert panel interpretation. Three categories of Clinical Practice Guidelines recommendations were developed: strong, conditional, and no recommendation. RECOMMENDATIONS: Strong recommendations were (1) use a validated measurement tool to identify frailty; (2) prescribe physical activity with a resistance training component; and (3) address polypharmacy by reducing or deprescribing any inappropriate/superfluous medications. Conditional recommendations were (1) screen for, and address modifiable causes of fatigue; (2) for persons exhibiting unintentional weight loss, screen for reversible causes and consider food fortification and protein/caloric supplementation; and (3) prescribe vitamin D for individuals deficient in vitamin D. No recommendation was given regarding the provision of a patient support and education plan. CONCLUSIONS: The recommendations provided herein are intended for use by healthcare providers in their management of older adults with frailty in the Asia Pacific region. It is proposed that regional guideline support committees be formed to help provide regular updates to these evidence-based guidelines.

RESUMEN

The survival of HIV-infected persons has been increasing over the last years, thanks to the implementation of more effective pharmacological and non-pharmacological interventions. Nevertheless, HIV-infected persons are often "biologically" older than their "chronological" age due to multiple clinical, social, and behavioral conditions of risk. The detection in this population of specific biological features and syndromic conditions typical of advanced age has made the HIV infection an interesting research model of accelerated and accentuated aging. Given such commonalities, it is possible that "biologically aged" HIV-positive persons might benefit from models of adapted and integrated care developed over the years by geriatricians for the management of their frail and complex patients. In this article, possible strategies to face the increasingly prevalent geriatric syndromes in HIV-infected persons are discussed. In particular, it is explained the importance of shifting from the traditional disease-oriented approach into models of care facilitating a multidisciplinary management of frailty.

RESUMEN

The sustainability of healthcare systems is threatened by the increasing (absolute and relative) number of older persons referring to clinical services. Such global phenomenon is questioning the traditional paradigms of medicine, pushing towards the need of new criteria at the basis of clinical decision algorithms. In this context, frailty has been advocated as a geriatric condition potentially capable of overcoming the weakness of chronological age in the identification of individuals requiring adapted care due to their increased vulnerability to stressors. Interestingly, frailty poses itself beyond the concept of nosological conditions due to the difficulties at correctly framing traditional diseases in the complex and heterogeneous scenario of elders. Thus, frailty may play a key role in public health policies for promoting integrated care towards biologically aged individuals, currently presenting multiple unmet clinical needs. At the same time, the term frailty has also been frequently used in the literature for framing a physical condition of risk for (mainly functional) negative endpoints. The combination of such physical impairment with an organ-specific phenotype (e.g., the age-related skeletal muscle decline or sarcopenia) may determine the assumptions for the development of a clinical condition to be used as potential target for ad hoc interventions against physical disability. In the present article, we present the background of frailty and sarcopenia, and discuss their potentialities for reshaping current clinical and research practice in order to promote holistic approach to older patients, solicit personalization of care, and develop new targets for innovative interventions.
