Sarcopenia has come a long way since Irwin Rosenberg fi rst

suggested the term to use to historic period-related muscle mass.

i

This codifi ed the original report in 1931 by Critchley on loss

of muscle mass in the extremities with sometime historic period.

2

Extensive

piece of work past Baumgartner and his colleagues

iii,iv

established that

low muscle mass defined every bit lean appendicular mass/height

2

was a good predictor of future outcomes. He also established

that obese persons with sarcopenia had worse outcomes

than non-obese persons with sarcopenia and obese persons

with intact muscle mass.

5

This condition has subsequently

been termed sarcopenic obesity.

six–9

In 2010, the European Working Group on Sarcopenia de-

fined sarcopenia as low muscle mass together with depression

musculus function (strength or performance).

10

Afterwards,

other international groups developed similar defi nitions for

sarcopenia focusing on walking speed or distance walked in

six min or grip forcefulness in persons with lean muscle mass.

11–thirteen

A number of studies have confi rmed the validity of these

definitions.

14–xx

Finally, it was recently demonstrated that cutting-

offs for the defi nitions demand to exist ethnically sensitive.

21–23

Based on the available literature, information technology would announced that

sarcopenia is present in five to 10% of persons 65 years of age

or older.

24–26

This high quality research approach to sarcopenia has led

to the recognition of sarcopenia as a illness entity with the

awarding of an ICD-x-CM (M62.84) code in September,

2016 (www.prweb.com-prweb13376057). This is an impor-

tant footstep similar to the much earlier recognition of osteopo-

rosis equally a affliction state.

27

This volition lead to an accelerated

interest in physicians making the diagnosis of sarcopenia

and for pharmaceutical companies to advance the interest

in developing drugs to treat sarcopenia. This research will

be helped past there already being a number of biomarkers

available for sarcopenia.

28–30

This should as well drive an in-

crease in diagnostic tool availability for recognizing

sarcopenia.

31

Sarcopenia is the almost of import cause of frailty in older

persons.

32–36

In addition, there is a shut clan between

sarcopenia and bone loss and hip fracture-

osteosarcopenia.

37,38

Sarcopenia has as well been found to be

a major reason for poor outcomes in persons with diabetes

mellitus.

39,40

SARC-F is a simple screening test for sarcopenia.

41–43

It

prospectively identifi es decreased walking speed, activities

of daily living inability, hospitalization, and mortality.

44–46

It

has been shown to correlate well with the available interna-

tional defi nitions for sarcopenia.

There are numerous causes of sarcopenia including

anorexia,

47

inflammation,

48

hypogonadism,

49

lack of activ-

ity,

fifty

hypovitaminosis D,

51

motoneuron loss,

52,53

insulin

resistance,

54

poor blood fl ow to muscle,

55

mitochondrial

dysfunction,

56

and genetic causes.

57

The established treatment for sarcopenia is resistance ex-

ercise.

58–60

Information technology appears that sarcopenia is always responsive

to resistance practice.

61

Supplementation with leucine

enriched, essential amino acid can also enhance musculus reju-

venation.

62–65

Vitamin D declines with ageing, and supple-

mentation enhances muscle function when deficient.

Testosterone is the drug with the strongest tape for in-

creasing muscle mass and improving part.

68–lxx

Anamorelin improves musculus mass simply not forcefulness.

71

A

number of other drugs are under development focusing

mainly on myostatin and activin-2 receptor inhibitors.

72

Selective androgen receptor molecules (SARMs) have also

shown positive effects.

73

Overall, the availability of an ICD-10 code for those of united states

who piece of work in the area of muscle wasting disease is a very

exciting time.

74

Over the adjacent few years, we can wait

major advances in the treatment of older persons with

sarcopenia.

... Sarcopenia is a generalized and progressive skeletal muscle disorder that involves the accelerated loss of muscle mass and muscle role (1) and has been recognized equally an independent disease with an International Nomenclature of Diseases-10 lawmaking (M62.84) by the Globe Wellness System (WHO) in 2016 (2). Recognition of sarcopenia equally a disease has led to major inquiry efforts into the all-time screening, diagnosis, treatment, and management practices. ...

... Information technology retains 10 of the original domains, has xvi items in full (compared with 11 in the original), has simpler response categories than the original AMSTAR (21), includes a more comprehensive user guide, and has an overall rating based on weaknesses in critical domains (xx). Seven domains (item two,4,7,9,11,13,fifteen) tin critically bear upon the validity of a review and its conclusions be regarded every bit weaknesses. AMSTAR 2 does not have an overall score. ...

Background Many clinical practice guidelines strongly recommend do as an intervention for patients with sarcopenia. However, the significance of exercise on patient-of import outcomes in older adults with sarcopenia is inconsistent when considering bachelor minimal important differences. To synthesize current systematic review and meta-analyses evidence on the efficacy of do on patient-important outcomes in the treatment of sarcopenia in older adults. Methods Nosotros searched MEDLINE, EMBASE, Cochrane Library (Cochrane database of systematic review, CDSR) via OvidSP and Web of science until April 2021 and reference lists. Two independent investigators performed abstracted and title screening, assessed the total text and quality of evidence. This umbrella review included systematic reviews and meta-analyses of randomized controlled trials (RCTs). Eligible reviews aim to evaluate the effect of practise on patient-important sarcopenic outcomes (muscle or concrete function, mortality, and quality of life) in treating sarcopenia in older people. We used the minimally important differences (MIDs) of these outcomes to assess if the effects of practice matter to patients. Results This umbrella review provided a wide overview of the existing prove and evaluated the systematic reviews' methodological quality and show for all these associations. In older patients with sarcopenia, moderate- to loftier-quality evidence showed that do intervention probably increases walking speed and improved physical performance (measured past TUG test); do may increase the muscle strength (grip force, keen extension strength); only the outcome size for grip force probably too pocket-sized to achieve patients important changes. Prove for older people with sarcopenic obesity is express, and we found the consistent effect of exercise interventions on grip force and usual walking speed. Conclusion Exercise has a positive and important effect on concrete operation for older adults with sarcopenia, which supports leaving the current recommendations unchanged. New systematic reviews to summarize the effect of exercise on the quality of life are warranted to make full the current evidence gap.

Anthropometric measures and biochemical parameters were carried out for each patient. Sarcopenia was divers according to the Asian Working Group for Sarcopenia (AWGS) 2019 algorithm. Nutritional hazard/malnutrition was defined co-ordinate to the European Club of Clinical Nutrition and Metabolism (ESPEN) criteria. The logistic regression analysis was employed for the analysis of correlation between the SI and other variables. Cox regression analysis was employed to analyze correlation betwixt the SI and mortality.Results: A total of 758 participants agreed to participate in this study (589 men and 169 women; mean historic period: 85.6± 6.one years). The median of the follow-up period was 212 days. A full of 112 patients died. A high SI (per 1-SD was 22.1) was independently associated with all-crusade mortality (HR per 1-SD = 0.61, 95% CI: 0.47– 0.79), nutritional adventure/malnutrition (OR per 1-SD = 0.38, 95% CI: 0.29– 0.49) and sarcopenia (OR per 1-SD = 0.58, 95% CI: 0.45– 0.74). High SI was positively correlated with albumin (r = 0.32, P < 0.001), hemoglobin (r = 0.24, P < 0.001), trunk mass alphabetize (BMI) (r = 0.12, P = 0.001), waist circumference (WC) (r = 0.08, P = 0.046), calf circumference (CC) (r = 0.45, P < 0.001), paw grip strength (HGS) (r = 0.52, P < 0.001) and negatively correlated with triglyceride glucose (TyG) (r = − 0.11, P = 0.007).Determination: The SI based on serum cystatin C and creatinine is associated with long-term bloodshed, nutritional take a chance/malnutrition and sarcopenia in hospitalized older Chinese patients.Keywords: cystatin C, creatinine, nutritional run a risk, malnutrition, sarcopenia, mortality

... However, it should be noted that the prevalence of sarcopenia varies depending on the definition of sarcopenia employed, with ten% existence the about conservative approximate [ii]. In September 2016, sarcopenia was introduced in the ICD-10-CM [3], which represents a major step forward in the recognition of sarcopenia as a disease. Importantly, sarcopenia is associated with multiple negative health outcomes. ...

Groundwork Slumber duration may influence take chances for sarcopenia simply studies on this topic are deficient, specially from depression and- middle-income countries (LMICs). Thus, the aim of the present written report was to investigate the clan between slumber duration and sarcopenia among adults aged ≥ 65 years from 5 LMICs (China, Ghana, Bharat, Russian federation, South Africa). Methods Cross-sectional, customs-based data from the WHO study on global ageing and developed wellness (SAGE) were analysed. Sarcopenia was divers as having depression skeletal muscle mass (SMM) and weak handgrip forcefulness, while astringent sarcopenia was defined every bit having low SMM, weak handgrip strength, and deadening gait speed. Cocky-reported sleep duration in the past 2 nights were averaged and classified equally ≤ 6, > 6 to ≤ 9, and ≥ ix h/day. Multivariable logistic regression assay was conducted. Results Data on 13,210 adults aged ≥ 65 years [mean (SD) age 72.vi (11.3) years; 55.0% females] were analyzed. In the overall sample, compared to > 6 to ≤ nine h/day of sleep duration, > 9 h/day was associated with 1.70 (95% CI 1.xv–2.51) and 1.75 (95% CI 1.08–2.84) times college odds for sarcopenia and severe sarcopenia, respectively. No significant associations were observed among males, just associations were especially pronounced amidst females [i.due east., OR = 2.19 (95% CI 1.26–3.81) for sarcopenia, and OR = 2.26 (95% CI 1.20–iv.23) for astringent sarcopenia]. Conclusions Long sleep duration was associated with an increased odds of sarcopenia and astringent sarcopenia in LMICs, especially in females. Hereafter studies should investigate whether addressing long sleep duration amidst females can atomic number 82 to lower gamble for sarcopenia onset in LMICs.

Sensory impairments and sarcopenia are both highly prevalent age-related weather, with the former having been postulated to contribute to the pathogenesis of the latter status. Confirming this hypothesis may therefore assistance to better inform strategies for early handling and intervention of sarcopenia. Nosotros performed a systematic review of the electric current literature examining the relationships betwixt 4 major sensory impairments [vision (VI), hearing (HI), smell (SI), and taste (TI)] with (i) sarcopenia; and (ii) its associated components (low handgrip strength, ho-hum gait speed, and low muscle mass). PubMed, EMBASE, CINAHL, and Cochrane Library databases were searched for observational studies investigating the human relationship of 6, Hello, SI, and TI with sarcopenia, low handgrip forcefulness, tedious gait speed, and depression muscle mass, in adults anile 50 years or older, from inception until 24 May 2021. The take a chance of bias of the included studies was assessed using the Newcastle-Ottawa Calibration. This study was registered with PROSPERO, reference CRD42021247967. Ten cross-sectional and iii longitudinal population-based studies of customs-dwelling adults (Due north = 68 235) were included, with five studies investigating more than i sensory impairment. In full, 8, half dozen, 3, and one studies investigated the human relationship between VI, HI, SI, and TI and sarcopenia and its related components, respectively. Follow-up duration for the longitudinal studies ranged from 4 to 11 years. All studies had a low or moderate risk of bias. We found that the presence of VI and SI, but not TI, independently increased the odds of sarcopenia. In improver, 6 and SI were each independently associated with depression muscle mass; and VI, Hullo, and SI were each independently associated with deadening gait speed. Still, we found inconclusive evidence for the associations between Half-dozen, HI and SI, and low handgrip strength. Our systematic review suggests a potential association betwixt the presence of single or multiple sensory impairments and a greater likelihood of sarcopenia and/or deficits in its associated components, specially for Half dozen, HI, and SI. Prospective studies are needed to untangle the relationship between sensory impairment and sarcopenia to better inform clinical guidelines for disease prevention and management.

ZUSAMMENFASSUNG Sarkopenie bezeichnet laut aktueller Definitionen, z. B. der durch dice European Working Group on Sarcopenia in Older People (EWGSOP) im Jahre 2019 erstellten Definition, den Verlust an Muskelmasse, -kraft und -leistung. Von einer primären, altersbedingten Sarkopenie wird eine sekundäre unterschieden, zu deren Ursachen Immobilität, inadäquate Ernährung, Medikamente wie Glukokortikoide und systemische Erkrankungen, wie z. B. chronisch entzündliche Erkrankungen zählen. Die in der Literatur berichtete Prävalenz der Sarkopenie bei entzündlich rheumatischen Erkrankungen variiert aufgrund verschiedener Definitionen und untersuchten Populationen stark, beträgt aber bei der rheumatoiden Arthritis ca. xxx %. Neben dem Alter sind erhöhte Entzündungsmediatoren, Glukokortikoid-Therapie, körperliche Inaktivität und Krankheitsdauer weitere Risikofaktoren. Eine Sarkopenie chapeau direkten Einfluss auf dice Mobilität und Eigenständigkeit älterer Menschen. Sie ist assoziiert mit einer erhöhten Gesamtsterblichkeit, Stürzen, Krankenhausaufenthalten sowie weiteren Funktionsparametern des täglichen Lebens. Im Behandlungsalltag kann die Sarkopenie durch einfache Assessments rasch erfasst werden. Therapieoptionen bestehen aus Bewegungs- und Krafttraining sowie einer ausgewogenen, proteinreichen Ernährung.

Background: Human being papillomavirus vaccination is not widespread in Japan, and the depression screening rates result in many cases of locally advanced cervical cancer. We investigated the prognostic significance of sarcopenia in patients with cervical cancer to guide healthcare policies to amend treatment outcomes. Methods: This retrospective written report included 83 patients with cervical cancer without distant metastasis who underwent primary concurrent chemoradiotherapy between 2013 and 2018. We analyzed the indicators of physical condition and muscle quantity using the SYNAPSE VINCENT software. Musculus mass and the human relationship betwixt treatment toxicity and prognosis were evaluated. Results: The patients' median age was 60 (range 33‒eighty) years. Cancer stage distribution was as follows: cT2b or college, 84.three%; N1, 65.ane%; and MA, 27.7%. The overall sarcopenia (skeletal muscle index [SMI] < 38.v) rate was thirty.ane%, and the rate was 33.9 and 22.ii% in patients aged < 64 and ≥ 65 years, respectively. No correlation was observed betwixt clinical stage and musculoskeletal indices. Treatment resulted in decreased body weight and SMI; after treatment, the sarcopenia rate increased to 37.3%. A college intramuscular adipose tissue content (IMAC) reduced the number of chemotherapy cycles needed. Treatment-associated SMI decreases of ≥ seven% indicated poor prognosis, with significant differences in progression-free survival and overall survival (p = 0.013 and p = 0.012, respectively). Patients who were very lean (body mass alphabetize < 18.five kg/m2) before treatment had a poor prognosis (p = 0.016 and p < 0.001). Conclusions: Our findings emphasize the importance of assessing original nutritional condition and maintaining muscle mass and quality during the treatment of patients with cervical cancer.

Groundwork: Sarcopenia is a affliction that involves skeletal muscle mass loss and is highly prevalent in the older adult population. Moreover, the incidence of sarcopenia is increased in patients with hypertension. Objectives: The study aimed to evaluate the association betwixt the classes of the drugs used for arterial hypertension treatment and the presence or absence of sarcopenia. Methods: 129 older adults with hypertension were evaluated past the researchers who registered the participants medication for arterial hypertension treatment. Sarcopenia level was measured by anthropometric parameters, muscular forcefulness, and functional capacity. The data were analyzed by one-manner ANOVA followed past post-hoc exam and Fisher'due south exact test; statistical significance was set up at 0.05. Results: Age was non different between women with different levels of sarcopenia, but significant differences were observed betwixt men with absent sarcopenia (66.viii±four.ii years) and men with probable sarcopenia (77.0±x.2 years). Individuals with absent sarcopenia showed higher handgrip strength (men: 33.eight±7.4, women: 23.2±4.half dozen Kgf) in comparison with those with sarcopenia (men with likely sarcopenia: ix.5±3.iii Kgf, women with probable, confirmed, and severe sarcopenia: 11.seven±ii.5, 12.two±3.0, 11.eight±1.8 Kgf, respectively). The analysis showed an association between the type of medication and caste of sarcopenia; diuretics were significantly associated with probable sarcopenia, and angiotensin Two receptor blockers (alone or in combination with diuretics) was associated with absence of sarcopenia. Determination: In conclusion, handgrip forcefulness was a adept method to diagnose sarcopenia, and diuretics were associated with increased risk of sarcopenia in older adults with hypertension.

Sarcopenia, the historic period-related skeletal muscle decline, is associated with relevant clinical and socioeconomic negative outcomes in older persons. The study of this phenomenon and the development of preventive/therapeutic strategies represent public health priorities. The present document reports the results of a contempo meeting of the International Working Group on Sarcopenia (a task strength consisting of geriatricians and scientists from academia and industry) held on June 7-viii, 2011 in Toulouse (French republic). The meeting was specifically focused at gaining knowledge on the currently available biomarkers (functional, biological, or imaging-related) that could be utilized in clinical trials of sarcopenia and considered the most reliable and promising to evaluate age-related modifications of skeletal musculus. Specific recommendations most the assessment of crumbling skeletal muscle in older people and the optimal methodological pattern of studies on sarcopenia were as well discussed and finalized. Although the study of skeletal musculus decline is still in a very preliminary phase, the potential corking benefits derived from a better agreement and treatment of this condition should encourage research on sarcopenia. However, the reasonable uncertainties (derived from exploring a novel field and the exponential dispatch of scientific progress) require the adoption of a cautious and comprehensive approach to the field of study.

Groundwork: Both loss of muscle mass (ie, sarcopenia) and obesity adversely impact clinically important outcomes in patients with chronic obstructive pulmonary disease (COPD). Currently, in that location are only a few studies in patients with COPD with sarcopenia and concurrent obesity, termed sarcopenic obesity (SO). Objective: To explore the effects of Then on exercise capacity, wellness condition, and systemic inflammation in COPD. Design/settings/participants: Baseline data nerveless from a total of 2548 participants (2000 patients with COPD, mean age (SD), 63.5 (7.ane) years; and 548 controls, 54.8 (nine.0) years) from ECLIPSE (Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints) report, a multicenter longitudinal observational study, were used. Measurements: All participants were divided into iv body composition phenotypes using bioelectrical impedance assay: (one) normal trunk composition, (ii) obesity, (3) sarcopenia, and (four) SO. In patients with COPD, the vi-minute walking altitude, illness-specific wellness status, and plasma inflammatory markers were compared among the respective trunk composition groups. Results: Patients with COPD were 3 times more than probable to nowadays with And so compared with controls without COPD (odds ratio [OR] 3.3, 95% confidence interval [CI] ii.0-five.4, P < .001). In patients with COPD, So was related to reduced 6-minute walking distance (-28.0 yard, 95% CI -45.6 to -x.4), P < .01) and to higher systemic inflammatory burden (an elevation of at least 2 inflammatory markers, OR 1.half dozen, 95% CI 1.1-2.v, P = .028) compared with the normal trunk limerick group after adjustments for historic period, sex, smoking, body mass index, and airflow limitation. Conclusions: Our findings advise that SO is associated with worse physical performance and higher systemic inflammatory brunt compared with other trunk composition phenotypes in patients with COPD. Trial registry: ClinicalTrials.gov no. NCT00292552.

Skeletal muscles undergo structural and functional reject with ageing, culminating in sarcopenia. The underlying neuromuscular mechanisms have been the subject of intense investigation, revealing mitochondrial abnormalities as potential culprit within both nerve and muscle cells. Implicated mechanisms involve dumb mitochondrial dynamics, reduced organelle biogenesis and quality command via mitophagy, accumulation of mitochondrial Deoxyribonucleic acid (mtDNA) damage and respiratory concatenation defect, metabolic disturbance, pro-apoptotic signalling, and oxidative stress. This commodity provides an overview of the cellular mechanisms whereby mitochondria may promote maladaptive changes inside motor neurons, the neuromuscular junction (NMJ), and musculus fibres. Lifelong physical activity, which promotes mitochondrial wellness beyond tissues, is emerging equally an effective countermeasure for sarcopenia. This article is protected by copyright.

Objectives: Diabetes mellitus is associated with premature crumbling, and chronic diabetes is associated with significant physical and cognitive complications. We aimed to examine frailty and sarcopenia rates and six-month health outcomes in a clinic-based sample of patients with diabetes. Design: This study was an observational study. Participants were recruited from June 2014 to Baronial 2014, and follow-up was conducted 6 months after mean solar day of screening. Setting: Participants were recruited at outpatient endocrinology, geriatric, and internal medicine clinics affiliated with Saint Louis Academy in St. Louis, Missouri. Participants: Participants were persons with diabetes mellitus ages l to 90. Measurements: Frailty and sarcopenia were identified using the Frail and SARC-F screens, respectively. A chart review of the patient'due south health record was performed on day of screening and at follow-upwards. A half dozen-calendar month phone questionnaire was performed to evaluate wellness outcomes. Logistic regressions were used to evaluate health outcomes. Results: A total of 198 persons with diabetes were recruited. Of the sample, 32.3% of sample was nonfrail, 38.9% was prefrail, and 28.8% was frail; 29.iii% of the sample was identified to have sarcopenia. Prefrail [odds ratio (OR) two.92, 95% confidence interval (CI) 1.15-seven.42; P = .025] and frail (OR 4.70, 95% CI 1.67-thirteen.19; P = .003) participants were more probable to be hospitalized overnight at vi-month follow-upward. Frail (OR 3.57 95% CI 1.27-ten.04; P = .016) participants were more than likely to have a new activities of daily living (ADL) disability at follow-upwards; this clan was not present for prefrail participants (OR ane.30, 95% CI .50-3.37; P = .59). Participants with sarcopenia were more likely to be hospitalized (OR 3.fourscore, 95% CI 1.67-8.61; P = .001) and to have a new ADL disability (OR 4.24, 95% CI ane.76-10.18; P = .001) at 6-month follow-upwards. Conclusions: Amidst dispensary patients with diabetes mellitus ages 50-ninety year sometime, frailty and sarcopenia prevalence is high, and both syndromes are predictors of beingness hospitalized overnight and new ADL disability after six months.

Blazon ii diabetes, a common metabolic affliction in older people, is a major risk gene for functional limitation, dumb mobility, and loss of independence. In older people, the pathogenesis of functional limitation and disability is complex and multifactorial. A number of potential pathways are involved including cardiovascular disease, peripheral neuropathy, overweight, osteoarthritis, visual deficit, and cognitive impairment, conditions that are all more prevalent among patients with diabetes. Sarcopenia, a geriatric condition characterized by a progressive and generalized loss of skeletal muscle mass and force, is also involved in the pathogenesis of functional limitations and disability. Recent research has shown that older patients with type 2 diabetes are often affected by skeletal muscle impairment, leading to reduced muscle strength and concrete function. Insulin resistance, hyperglycemia, muscle fat infiltration, and peripheral neuropathies are hypothesized as the cardinal biological mechanisms leading to musculus impairment in people with diabetes. This review summarizes the current literature on the biological pathways responsible for skeletal musculus dysfunction in type 2 diabetes and analyzes the role of refuse in muscle force and quality on the association between diabetes and mobility disability.

Sarcopenia was recently classified a geriatric syndrome and is a major challenge to healthy crumbling. Affected patients tend to accept worse clinical outcomes and higher mortality than those without sarcopenia. Although there is full general understanding on the principal diagnostic characteristics, initial thresholds for muscle mass, strength, and concrete performance were based on information from populations of predominantly Europid ancestry and may not apply worldwide. The Asian Working Group for Sarcopenia (AWGS) issued regional consensus guidelines in 2014, and many more than enquiry studies from Asia have since been published; this review summarizes recent progress. The prevalence of sarcopenia estimated by the AWGS criteria ranges between 4.1% and 11.5% of the general older population; however, prevalence rates were higher in Asian studies that used European Working Group on Sarcopenia in Older People cut-offs. Risk factors include age, sex, eye disease, hyperlipidemia, daily alcohol consumption, and low protein or vitamin intake; physical activity is protective. Adjusting skeletal muscle mass by weight rather than top is better in showing the effect of older age in sarcopenia and identifying sarcopenic obesity; however, some Asian studies constitute no pregnant skeletal muscle loss, and musculus strength might exist a meliorate indicator. Although AWGS 2014 diagnostic cut-offs were generally well accustomed, some may require farther revision in light of conflicting evidence from some studies. The importance of sarcopenia in diverse therapeutic areas is increasingly axiomatic, with strong research interest in sarcopenic obesity and the setting of malignancy. Pharmacologic interventions have been unsatisfactory, and the core direction strategies remain physical exercise and nutritional supplementation; however, farther research is required to determine the nearly beneficial approaches.

In the last decade, it has become articulate that older persons who are delicate or sarcopenic accept very high rates of functional deterioration, hospitalization, and decease. Recently, it has become recognized that simple screening questionnaires, e.g., the Delicate and SARC-F, perform as well every bit more complex testing for the physical phenotype screen and sarcopenia. In this article, nosotros provide a simple algorithm for the management of frailty. The multiple factors responsible for the pathogenesis of sarcopenia are reviewed, focusing on the importance of age-associated loss of motor units innervating muscle. Direction of sarcopenia includes resistance practise, leucine-enriched protein, and vitamin D. A number of newer drugs are under development. General practitioners should be encouraged to screen for frailty and sarcopenia in older persons.
