Summary There is no clear consensus on definition , cut-points or st and ardised assessment s of sarcopenia . We found a lower limb strength assessment  was at least as effective in predicting balance , mobility and falls in 419 older people as muscle mass-based measures of sarcopenia . Introduction There is currently no consensus on the definition , cut-points or st and ardised assessment s of sarcopenia . This study aim ed to investigate whether several published definitions of sarcopenia differentiate between older people with respect to important functional and health outcomes . Methods Four hundred nineteen community-living older adults ( mean age 81.2 ± 4.5 , 49 % female ) completed assessment s of body composition ( dual-energy X-ray absorptiometry ) , strength , balance , mobility and disability . Falls were recorded prospect ively for a year using monthly calendars . Sarcopenia was defined according to four skeletal mass-based definitions , two strength-based definitions ( h and grip or knee extensor force ) and a consensus algorithm ( low mass and low strength or slow gait speed ) . Obesity was defined according to percentage fat mass or waist circumference . Results The four skeletal mass-based definitions varied considerably with respect to the percentage of participants classified as sarcopenic and their predictive accuracy for functional and health outcomes . The knee extension strength-based definition was equivalent to or better than the mass-based and consensus algorithm definitions ; i.e. weaker participants performed poorly in tests of leaning balance , stepping reaction time , gait speed and mobility . They also had higher physiological fall risk scores and were 43 % more likely to fall at home than their stronger counterparts . Adding obesity to sarcopenia definitions identified participants with greater self-reported disability . Conclusions A simple lower limb strength assessment was at least as effective in predicting balance , functional mobility and falls in older people as more expensive and time-consuming muscle mass-based measures . These findings imply that functional terms such as muscle weakness or motor impairment are preferable to sarcopenia INTRODUCTION Ovarian cancer is the leading cause of death among gynecological malignancies . Its usual clinical manifestation is at advanced stages , with nutritional impairment , weight loss , and a consequent decline in skeletal muscle mass and strength ( defined as sarcopenia ) . The relationship between sarcopenia and decreased survival was demonstrated not only in ovarian cancer but also in other cancer types , such as hepatocellular , pancreatic , lung , colon , cervical , metastatic breast , and renal cancer . The aim of this study is to review the current evidence regarding the relationship between sarcopenia and the surgical and oncological outcomes in ovarian cancer patients . METHODS The systematic search was performed according to the Preferred Reporting Items for Systematic Review s and Meta-Analyses ( PRSIMA ) statement . The terms " SARCOPENIA " AND " OVARIAN CANCER " were systematic ally used to search PubMed and Scopus data bases . Original reports in English language were identified , with the purpose to include all relevant papers regarding the role of sarcopenia and indicators of skeletal muscle quality assessment in gynecological ovarian cancer . RESULTS A total of 9 studies were considered eligible for the present review . The strength of recommendation was moderate and the level of evidence was low in all selected articles . No prospect i ve studies were conducted and most of the papers were case-control series comparing ovarian cancer sarcopenic population vs. non sarcopenic population . CONCLUSIONS Sarcopenia appears to have an important role in oncological outcomes of ovarian cancer patients . However , sarcopenia occurrence during disease history and mechanisms underlying the possible impairment in prognosis should be better investigated . Prospect i ve trials are awaited in order to obtain a better insight in this topic BACKGROUND & AIM Sarcopenia , the age-related decrease in muscle mass , strength , and function , is a main cause of reduced mobility , increased falls , fractures and nursing home admissions . Cross-sectional and prospect i ve studies indicate that sarcopenia may be influenced in part by reversible factors like nutritional intake . The aim of this study was to compare functional and nutritional status , body composition , and quality of life of older adults between age and sex-matched older adults with and without sarcopenia . METHODS In a multi-centre setting , non-sarcopenic older adults ( n = 66 , mean ± SD : 71 ± 4 y ) , i.e. Short Physical Performance Battery ( SPPB ) : 11 - 12 and normal skeletal muscle mass index , were recruited to match 1:1 by age and sex to previously recruited adults with sarcopenia : SPPB 4 - 9 and low skeletal muscle mass index . Health-related quality of life , self-reported physical activity levels and dietary intakes were measured using the EQ-5D scale and index , Physical Activity Scale for the Elderly ( PASE ) , and 3-day prospect i ve diet records , respectively . Concentrations of 25-OH-vitamin D , α-tocopherol ( adjusted for cholesterol ) , folate , and vitamin B-12 were assessed in serum sample s. RESULTS In addition to the defined components of sarcopenia , i.e. muscle mass , strength and function , reported physical activity levels and health-related quality of life were lower in the sarcopenic adults ( p < 0.001 ) . For similar energy intakes ( mean ± SD : sarcopenic , 1710 ± 418 ; non-sarcopenic , 1745 ± 513 , p = 0.50 ) , the sarcopenic group consumed less protein/kg ( -6 % ) , vitamin D ( -38 % ) , vitamin B-12 ( -22 % ) , magnesium ( -6 % ) , phosphorus ( -5 % ) , and selenium ( -2 % ) ( all p < 0.05 ) compared to the non-sarcopenic controls . The serum concentration of vitamin B-12 was 15 % lower in the sarcopenic group ( p = 0.015 ) , and all other nutrient concentrations were similar between groups . CONCLUSIONS In non-malnourished older adults with and without sarcopenia , we observed that sarcopenia substantially impacted self-reported quality of life and physical activity levels . Differences in nutrient concentrations and dietary intakes were identified , which might be related to the differences in muscle mass , strength and function between the two groups . This study provides information to help strengthen the characterization of this geriatric syndrome sarcopenia and indicates potential target areas for nutritional interventions The age-related change in hormone concentrations has been hypothesized to play a role in the loss of muscle mass and muscle strength with aging , also called sarcopenia . The aim of this prospect i ve study was to investigate whether low serum 25-hydroxyvitamin D ( 25-OHD ) and high serum PTH concentration were associated with sarcopenia . In men and women aged 65 yr and older , participants of the Longitudinal Aging Study Amsterdam , grip strength ( n = 1008 ) and appendicular skeletal muscle mass ( n = 331 , using dual-energy x-ray absorptiometry ) were measured in 1995 - 1996 and after a 3-yr follow-up . Sarcopenia was defined as the lowest sex-specific 15th percentile of the cohort , translating into a loss of grip strength greater than 40 % or a loss of muscle mass greater than 3 % . After adjustment for physical activity level , season of data collection , serum creatinine concentration , chronic disease , smoking , and body mass index , persons with low ( < 25 nmol/liter ) baseline 25-OHD levels were 2.57 ( 95 % confidence interval 1.40 - 4.70 , based on grip strength ) and 2.14 ( 0.73 - 6.33 , based on muscle mass ) times more likely to experience sarcopenia , compared with those with high ( > 50 nmol/liter ) levels . High PTH levels ( > or=4.0 pmol/liter ) were associated with an increased risk of sarcopenia , compared with low PTH ( < 3.0 pmol/liter ) : odds ratio = 1.71 ( 1.07 - 2.73 ) based on grip strength , odds ratio = 2.35 ( 1.05 - 5.28 ) based on muscle mass . The associations were similar in men and women . The results of this prospect i ve , population -based study show that lower  25-OHD  and higher  PTH levels increase the risk of sarcopenia in older men and women Objective Cancer cachexia is a paraneoplastic syndrome comprising involuntary weight loss and muscle depletion ( sarcopenia ) . Although weight loss has been associated with poor clinical outcome , there is only limited information on the prevalence and prognostic impact of sarcopenia in ovarian cancer so far . Methods Total skeletal muscle mass was determined by computed tomography image analysis of the third lumbar skeletal muscle cross-sectional area in 128 patients with advanced serous ovarian cancer . Longitudinal change of muscle mass was studied in  209 consecutive computed tomography scans  from 43 patients . Association with survival was determined using Cox proportional hazards model . Results The prevalence of sarcopenia at first diagnosis was 11 % ( 12/105 ; 95 % confidence interval [ CI ] , 6%–20 % ) . Sarcopenic patients had a significantly reduced progression-free ( hazard ratio , 2.64 ; 95 % CI , 1.24–5.64 ; P = 0.012 ) and overall survival ( hazard ratio , 3.17 ; 95 % CI , 1.29–7.80 ; P = 0.012 ) . On multivariable analysis , these prognostic effects remained significant after adjustment for age , International Federation of Gynecology and Obstetrics stage , and postsurgical residual disease . Longitudinal analyses identified both patients with loss and gain of muscle mass . However , change in muscle mass over time was not associated with survival . Conclusions Baseline sarcopenia is a prognostic factor in advanced serous ovarian cancer . Identification of sarcopenic patients and early enrollment in physical or nutritional education programs might thus be a feasible way to improve outcome and should be further evaluated in prospect i ve clinical trials AIM To develop a simple screening test to identify older adults at high risk for sarcopenia . METHODS We studied 1971 functionally independent , community-dwelling adults aged 65 years or older r and omly selected from the resident register of Kashiwa city , Chiba , Japan . Data collection was carried out between September and November 2012 . Sarcopenia was defined based on low muscle mass measured by bioimpedance analysis and either low muscle strength characterized by h and grip or low physical performance characterized by slow gait speed . RESULTS The prevalence of sarcopenia was 14.2 % in men and 22.1 % in women . After the variable selection procedure , the final model to estimate the probability of sarcopenia included three variables : age , grip strength and calf circumference . The area under the receiver operating characteristic curve , a measure of discrimination , of the final model was 0.939 with 95 % confidence interval ( CI ) of 0.918 - 0.958 for men , and 0.909 with 95 % CI of 0.887 - 0.931 for women . We created a score chart for each sex based on the final model . When the sum of sensitivity and specificity was maximized , sensitivity , specificity , and positive and negative predictive values for sarcopenia were 84.9 % , 88.2 % , 54.4 % , and 97.2 % for men , 75.5 % , 92.0 % , 72.8 % , and 93.0 % for women , respectively . CONCLUSIONS The presence of sarcopenia could be detected using three easily obtainable variables with high accuracy . The screening test we developed could help identify functionally independent older adults with sarcopenia who are good c and i date s for intervention Purpose Sarcopenia is distinguished by decreased skeletal muscle plus low muscle strength and /or physical performance . This study was design ed to demonstrate the relationship between sarcopenia and systemic inflammatory response ( neutrophil/lymphocyte ratio [ NLR ] , platelet/lymphocyte ratio [ PLR ] , and large platelet/lymphocyte ratio [ LPLR ] ) prior to radical gastrectomy for gastric cancer . Patients and methods We conducted a prospect i ve study of gastric cancer patients who underwent radical gastrectomy .  The clinical utility of the NLR , PLR , and LPLR was evaluated by receiver operating characteristic curves . Sarcopenia components including skeletal muscle index , h and grip strength , and 6 m usual gait speed were measured . Logistic analysis was used to identify the independent indices associated with sarcopenia . Results A total of 670 patients were included , representing 504 men and 166 women . Of these , 104 patients ( 15.5 % ) were diagnosed with sarcopenia and 567 ( 84.5 % ) were non-sarcopenia . PLR has a diagnostic sensitivity of 91.3 % for sarcopenia . In addition to the indicators of preoperative age , nutritional risk screening , body mass index , preoperative albumin , and diabetes , the NLR and PLR were independent predictors for sarcopenia ( P<0.05 ) . Conclusion The present study showed that at-diagnosis sarcopenia was associated with inflammation in patients with operable gastric cancer . Due to the complex assessment of muscle condition , PLR may be used as a primary screening test for sarcopenia . How systemic inflammatory response influences changes in sarcopenia may provide new therapeutic perception toward improving outcomes OBJECTIVE The aim of the Intervention by Nutrition and Exercise ( INE ) study was to investigate the effects of a mail-based intervention for sarcopenia prevention on muscle mass and anabolic hormones in community-dwelling older adults . DESIGN A cluster-r and omized controlled trial . SETTING AND PARTICIPANTS This trial recruited community-dwelling adults aged 65 years and older in Japan . The 227 participants were cluster r and omized into a  walking and nutrition ( W/N ) group ( n = 79 ) , a  walking ( W ) group ( n = 71 ) , and a  control ( C ) group ( n = 77 ) . We analyzed the physical and biochemical measurements in this sub study . INTERVENTION Six months of mail-based intervention ( a pedometer-based walking program and nutritional supplementation ) . MEASUREMENTS The skeletal muscle mass index ( SMI ) using the bioelectrical impedance data acquisition system , biochemical measurements , such as those of insulinlike growth factor ( IGF-1 ) , dehydroepi and rosterone sulfate ( DHEA-S ) , and 25-hydroxy vitamin D ( 25[OH]D ) , as well as frailty , were assessed by the Cardiovascular Health Study criteria . RESULTS Participants in the W/N and W groups had significantly greater improvements in SMI , IGF-1 , and 25(OH)D ( P < .05 ) than those in the C group . Participants in the W/N group had significantly greater improvements in DHEA-S ( P < .05 ) than in the other groups . These effects were more pronounced in frail , older adults . CONCLUSION These results suggest that the mail-based walking intervention of the remote monitoring type for sarcopenia prevention can increase anabolic hormone levels and SMI in community-dwelling older adults , particularly in those who are frail Muscle mass decreases with age , leading to " sarcopenia , " or low relative muscle mass , in elderly people . Sarcopenia is believed to be associated with metabolic , physiologic , and functional impairments and disability . Methods of estimating the prevalence of sarcopenia and its associated risks in elderly population s are lacking . Data from a  population -based survey of 883 elderly Hispanic and non-Hispanic white men and women living in New Mexico ( the New Mexico Elder Health Survey , 1993 - 1995 ) were analyzed to develop a method for estimating the prevalence of sarcopenia . An anthropometric equation for predicting appendicular skeletal muscle mass was developed from a r and om sub sample ( n = 199 ) of participants and was extended to the total sample . Sarcopenia was defined as appendicular skeletal muscle mass (kg)/height2 ( m2 ) being less than two st and ard deviations below the mean of a young reference group . Prevalences increased from 13 - 24 % in persons under 70 years of age to > 50 % in persons over 80 years of age , and were slightly greater in Hispanics than in non-Hispanic whites . Sarcopenia was significantly associated with self-reported physical disability in both men and women , independent of ethnicity , age , morbidity , obesity , income , and health behaviors . This study provides some of the first estimates of the extent of the public health problem posed by sarcopenia AIM Texture-modified diets ( TMD ) have significantly lower energy and protein content than normal diets . Therefore , TMD can cause malnutrition and loss of muscle mass . However , few studies have reported the relationship between TMD and decreased skeletal muscle mass . The aim of the present study was to clarify the association between TMD and decreased skeletal muscle mass . METHODS We review ed data of 188 older adult patients who were admitted to a rehabilitation hospital . TMD were defined based on the Japanese Dysphagia Diet Criteria 2013 proposed by the Japanese Society of Dysphagia Rehabilitation . The Mini Nutritional Assessment -Short Form was used to assess nutritional status ;  dual-energy X-ray absorptiometry was used to measure the skeletal muscle mass index , and the cut-off values for decreased skeletal muscle mass index were based on the Asian Working Group for Sarcopenia ; the Functional Independence Measure was used to evaluate activities of daily living . RESULTS The patients ' mean age was 80.6 ± 7.5 years , and 62 % were women . A total of 22 patients ( 11.7 % ) consumed TMD . A total of 104 patients ( 55.3 % ) had decreased skeletal muscle mass , and approximately 90 % of them consumed TMD . Decreased skeletal muscle mass index ( odds ratio 7.199 , 95 % confidence interval 1.489 - 34.805 , P ≤ 0.01 ) and Functional Independence Measure scores ( odds ratio 0.972 , 95 % confidence interval 0.952 - 0.992 , P ≤ 0.01 ) were independently related to TMD in the multivariate analysis . CONCLUSIONS The TMD group was associated with decreased skeletal muscle mass . Future , prospect i ve studies are necessary to investigate causality . Geriatr Gerontol Int 2018 ; 18 : 698 - 704 BACKGROUND AND AIMS sarcopenia has been indicated as a reliable marker of frailty and poor prognosis among the oldest individuals . We evaluated the impact of sarcopenia on the risk of all-cause death in a population of frail older persons living in community . METHODS we analysed data from the Aging and Longevity Study , a prospect i ve cohort study that collected data on all subjects aged 80 years and older residing in the Sirente geographic area ( n = 364 ) . The present analysis was conducted among those subjects who were between 80 and 85 years of age at the time of the baseline assessment ( n = 197 ) . The main outcome measure was all-cause mortality over 7-year follow-up . According to the European Working Group on Sarcopenia in Older People ( EWGSOP ) criteria , the diagnosis of sarcopenia required the documentation of low muscle mass and the documentation of either low muscle strength or low physical performance . Cox proportional regression models were used to estimate crude and adjusted hazard ratios and 95 % confidence intervals of death by the presence of sarcopenia . RESULTS using the EWGSOP-suggested criteria , 43 subjects with sarcopenia ( 21.8 % ) were identified . During the 7-year follow-up , 29 ( 67.4 % ) participants died among subjects with sarcopenia compared with 63 subjects ( 41.2 % ) without sarcopenia ( P < 0.001 ) . After adjusting for potential confounders including age , gender , education , activities of daily living ( ADL ) impairment , body mass index , hypertension , congestive heart failure , chronic obstructive pulmonary disease , number of diseases , TNF-α , participants with sarcopenia had a higher risk of death for all causes compared with non-sarcopenic subjects ( HR : 2.32 , 95 % CI : 1.01 - 5.43 ) . CONCLUSIONS our results obtained from a representative sample of very old and frail subjects show that sarcopenia is associated with mortality , independently of age and other clinical and functional variables Objective : The aim of this article was to study the prevalence and significance of sarcopenia in the multimodal management of locally advanced esophageal cancer ( LAEC ) , and to assess its independent impact on operative and oncologic outcomes . Summary of Background Data : Sarcopenia in cancer may confer negative outcomes , but its prevalence and impact on modern multimodal regimens for LAEC have not been systematic ally studied . Methods : Two hundred fifty-two consecutive patients were studied .  Lean body mass ( LBM ) , skeletal muscle index ( SMI ) , and fat mass ( FM ) were determined pre-treatment , preoperatively , and 1 year postoperatively . Sarcopenia was defined by computed tomography ( CT ) at L3 as SMI < 52.4 cm2/m2 for males and SMI < 38.5 cm2/m2 for females . All complications were recorded prospect ively , including comprehensive complications index ( CCI ) , Clavien-Dindo complication ( CDC ) , and pulmonary complications ( PPCs ) . Multivariable linear , logistic , and Cox regression analysis was performed . Results : In-hospital mortality was 1 % , and CCI was 21 ± 19 . Sarcopenia increased ( P = 0.02 ) from 16 % at diagnosis to 31 % post-neoadjuvant therapy , with loss of LBM ( -3.0 ± 5.4 kg , P < 0.0001 ) , but not FM ( -0.3 ± 2.7 kg , P= 0.31 ) during treatment . On multivariable analysis , preoperative sarcopenia was associated with CCI ( P = 0.043 ) , and CDC ≥IIIb ( P = 0.003 ) . PPCs occurred in 36 % nonsarcopenic versus 55 % sarcopenic patients ( P = 0.01 ) . Sarcopenia did not impact disease-specific ( P = 0.14 ) or overall survival ( P = 0.11 ) after resection . At 1 year , 35 % had sarcopenia , significantly associated with pre-treatment BMI ( P = 0.013 ) but not complications ( P = 0.20 ) . Conclusions : Sarcopenia increases through multimodal therapy , is associated with an increased risk of major postoperative complications , and is prevalent in survivorship . These data highlight a potentially modifiable marker of risk that should be assessed and targeted in modern multimodal care pathways OBJECTIVES To cross-culturally adapt and vali date the Spanish- language version of the SARC-F  in Mexican community-dwelling older adults . DESIGN Cross-sectional analysis of a prospect i ve cohort . SETTING The FraDySMex study , a 2-round evaluation of community-dwelling adults from 2 municipalities in Mexico City . PARTICIPANTS Participants were 487 men and women older than 60 years , living in the design ated area in Mexico City . MEASUREMENTS Information from question naires regarding demographic characteristics , comorbidities , mental status , nutritional status , dependence in activities of daily living , frailty , and quality of life . Objective measurements of muscle mass , strength and function were as follows : skeletal muscle mass index ( SMI ) was taken using dual-energy x-ray , grip strength using a h and dynamometer , 6-meter gait speed using a GAIT Rite instrumented walkway , peak torque and power for knee extension using a isokinetic dynamometer , lower extremity functioning measured by the Short Physical Performance Battery ( SPPB ) , and balance using evaluation on a foam surface , with closed eyes , in the Modified Clinical Test of Sensory Integration . The SARC-F scale translated to Spanish and the consensus panels ' criteria from European , international , and Asian sarcopenia working groups were applied to evaluate sarcopenia . RESULTS The Spanish language version of the SARC-F scale showed reliability ( Cronbach alfa = 0.641 . All items in the scale correlated to the scale 's total score , rho = 0.43 to 0.76 ) , temporal consistency evaluated by test-retest ( CCI = 0.80 ) , criterion validity when compared to the consensus panels ' criteria ( high specificity and negative predictive values ) . The scale was also correlated to other measures related to sarcopenia ( such as age , quality of life , self-rated health status , cognition , dependence in activities of daily living , nutritional status , depression , gait speed , grip strength , peak torque and power for knee extension , SPPB , balance , SMI , and frailty ) . CONCLUSION The SARC-F scale was successfully adapted to Spanish language and vali date d in community-dwelling Mexican older adults BACKGROUND Computed tomography ( CT ) can be used for accurate estimation of whole-body muscle mass and muscle density and for detection of sarcopenia . The goal of this study was to evaluate the additional value of CT measured sarcopenia and muscle attenuation alongside the Malnutrition Universal Screening Tool ( MUST ) for the prediction of post-operative morbidity after oncological colorectal resection , whilst correcting for known risk factors . METHODS A prospect i ve cohort study of 80 patients undergoing elective colorectal surgery in the Netherl and s. Patients were screened for nutritional risk upon admission using the MUST . Additionally , preoperative CT scans were used to determine skeletal muscle mass for the detection of sarcopenia and muscle attenuation . Univariate and multivariable analyses were performed to evaluate associations between the MUST , muscle attenuation and sarcopenia on the one h and and post-operative complications measured by the Clavien-Dindo score on the other h and . RESULTS American Society of Anesthesiology-classification ( ASA ) ≥3 , age ≥70 , MUST ≥2 and lower than median muscle attenuation were significantly associated with a higher risk for postoperative complications ( Clavien-Dindo score ≥2 ) ( p ≤ 0.05 ) , whereas sarcopenia was not ( p = 0.59 ) . Multivariate analyses showed that only MUST ≥2 remained significantly associated with postoperative complications when corrected for age ( p = 0.03 , OR 5.8 , 95%CI 1.1 - 29.6 ) , but not when corrected for age ≥70 and ASA ≥3 . Muscle attenuation and sarcopenia were not significantly associated with postoperative complications . CONCLUSION Our results suggest that using CT measured sarcopenia may have only little additional value over the MUST for the prediction of increased short-term post-operative morbidity after oncological colorectal surgery . It also underlines the importance of currently implemented easy-to-use nutritional screening tools ( MUST ) and raises the question of the evaluation of muscle quality versus quantity in body composition imaging . However , further research is needed to investigate the role of sarcopenia for predicting outcome after colorectal surgery , and investigate the role of muscle attenuation measurements for the prediction of muscle function . CATEGORY OF SU BMI SSION : observational study OBJECTIVES Severe skeletal muscle loss ( sarcopenia ) is associated with poor cancer outcomes , including reduced survival and increased treatment toxicity . Our goal was to evaluate if sarcopenia was associated with worse survival outcomes and chemotoxicity in EOC patients undergoing primary platinum and taxane-based chemotherapy .  METHODS EOC patients diagnosed between 06/2000 and 02/2017 who received treatment with platinum and taxane-based chemotherapy were included .  CT abdominal images closest to the time of diagnosis were retrospectively evaluated for skeletal muscle area at the 3rd lumbar vertebrae . Measurements were obtained with use of TomoVision ® radiological software ( SliceOmatic - version 5.0 , Quebec , Canada ) . Sarcopenia was defined as Skeletal Muscle Index ( SMI ) ≤ 41 . Data analysis included Kaplan-Meier plots to assess survival , and unpaired t-tests were used to compare the means by groups . RESULTS 201 EOC patients were evaluated . Sixty-four percent ( 128/201 ) met criteria for sarcopenia ( SMI ≤ 41 ) at time of diagnosis . The mean overall survival did not differ between patients with SMI > 41 and SMI ≤ 41 ( 36.5 vs 40.8 months , p = 0.4 , respectively ) . No difference in frequency of dose reduction , dose delay , hospital admissions , changes in regimen , blood transfusion , or toxicity was noted . There was no difference in distribution of toxicity grade . CONCLUSION Sarcopenia was not associated with worse survival outcomes or chemotoxcity in EOC patients receiving first-line platinum and taxane-based chemotherapy  in this cohort . Future prospect i ve studies should focus on interventions to prevent or reverse sarcopenia and possibly increase ovarian cancer survival , performance status , and quality of life OBJECTIVES To determine the effects of ultra-low-dose hormone therapy on muscle mass and physical function in community-dwelling women . DESIGN Double-blind , placebo-controlled trial . SETTING Clinical research center in Connecticut . PARTICIPANTS Healthy , community-dwelling women aged 65 and older ( n=167 ) . INTERVENTION Eligible women were r and omly assigned to treatment with 0.25 mg 17-beta estradiol or placebo for 36 months . All women ( estradiol or placebo ) with an intact uterus received micronized progesterone 100 mg/d for 2 weeks every 6 months . All participants received 1,300 mg elemental calcium with 1,000 IU vitamin D per day . MEASUREMENTS Appendicular skeletal muscle mass ( ASM ) , lean body mass ( LBM ) , and percentage body fat were measured using dual x-ray absorptiometry . Sarcopenia was defined as skeletal muscle mass ( ASM/height2 ) 2 st and ard deviations or less than young , healthy reference population mean . Physical activity ( Physical Activity Scale in the Elderly ( PASE ) ) and performance were measured . Serum estrone , estradiol , and sex hormone-binding globulin were measured . RESULTS The prevalence of sarcopenia at baseline was 13 % . There were no baseline differences between groups except for PASE score and chair rise time , in which the estrogen group had better performance . No changes in ASM , LBM , percentage of body fat , or physical performance were found after 3 years of estrogen therapy . CONCLUSION Sarcopenia was present in 13 % of this group of community-dwelling , postmenopausal older women . Ultra-low-dose estrogen therapy neither improves nor harms ASM . Similarly , no changes in body fat or physical performance were detected BACKGROUND Recent evidence suggests that nutritional interventions may improve muscle outcomes in malnutrition and sarcopenia . OBJECTIVES We evaluated the effects of 2 high- quality oral nutritional supplements ( ONS ) differing in amount and type of key nutrients in older adult men and women . DESIGN A multicenter , r and omized , double-blinded , controlled clinical trial . PARTICIPANTS Malnourished and sarcopenic men and women , 65 years and older ( n = 330 ) . INTERVENTION A 24-week intervention period with 2 energy-rich ( 330 kcal ) ONS treatment groups : Control ONS ( CONS , 14 g protein ; 147 IU vitamin D3 ) versus Experimental ONS ( EONS , 20 g protein ; 499 IU vitamin D3 ; 1.5 g CaHMB ) taken twice daily . Both ONS also contained other vitamins , minerals , and nutrients in varying amounts . MEASUREMENTS Isokinetic peak torque ( PT , Nm ) leg strength , grip strength ( kg ) , and gait speed ( m·s-1 ) were assessed at baseline and 12 and 24 weeks . Left and right leg muscle mass ( LMM , kg ) were assessed by dual-energy x-ray absorptiometry ( DXA ) . Muscle quality ( MQ ) was leg strength expressed relative to the tested LMM ( Nm·kg-1 ) . Subgroup analyses were performed : severe sarcopenia ( low skeletal mass index , low grip strength [ < 30 kg men ; < 20 kg women ] , low gait speed [ < 0.8 m·s-1 ] ) and mild-moderate sarcopenia ( low skeletal mass index , normal gait speed , or normal grip strength ) . RESULTS Both ONS groups ( EONS and CONS ) improved PT , MQ , grip strength , and gait speed from baseline with no treatment differences . Those with severe sarcopenia ( 44 % ) exhibited lower baseline PT and MQ , with no differences in strength improvements between treatments . However , participants with mild-moderate sarcopenia exhibited higher baseline PT and MQ , with differences in strength improvements at 12 weeks ( EONS > CONS , P = .032 ) in those with normal grip strength . There were no treatment differences based on sarcopenic severity for either grip strength or gait speed . CONCLUSION ONS improved strength outcomes in malnourished older adults with sarcopenia . In those with mild-moderate sarcopenia , but not severe sarcopenia , consumption of the EONS improved leg muscle strength and quality compared with the st and ard CONS Background / Objectives : This study aims to increase knowledge regarding the association of sarcopenia with hospitalization costs among a wide-ranging sample of adult hospitalized patients .Subjects/ Methods : A prospect i ve study was conducted among hospitalized adult patients . Sarcopenia was identified according to the European Working Group on Sarcopenia in Older People , as low muscle mass , assessed by bioelectrical impedance analysis and low muscle function evaluated by h and grip strength .  Hospitalization cost was calculated for each patient based on discharge diagnosis-related group codes and determined on the basis of a relative weight value . Costs were defined as the percentage of deviation from the cost of a patient with a relative weight equal to one . Multivariable linear regression models were performed to identify the factors independently associated with hospitalization costs . Results : A total of 656 hospitalized patients aged ⩾18 years ( 24.2 % sarcopenic ) composed the study sample . Sarcopenia increased hospitalization costs by [ euro ] 1240 ( 95 % confidence interval ( CI ) : [ euro ] 596–1887 ) for patients aged < 65 years and [ euro ] 721 ( 95 % CI : [ euro ] 13–1429 ) for patients aged ⩾65 years . Sarcopenic overweight was related to an increase in hospitalization costs of [ euro ] 884 ( 95 % CI : [ euro ] 295–1476 ) . Conclusions : Sarcopenia is independently related to hospitalization costs . This condition is estimated to increase hospitalization costs by 58.5 % for patients aged < 65 years and 34 % for patients aged ⩾65 years Summary Sarcopenia may be diagnosed in the clinic using operational definitions based on low muscle mass or function . This prospect i ve , population -based study revealed that sex-specific associations may exist between operational definitions of sarcopenia and falls in community-dwelling middle-aged and older adults . Introduction The objective of this study is to verify associations between sarcopenia and falls risk and to determine changes in sarcopenia prevalence over 5 years in middle-aged and older men and women according to different anthropometric and performance-based operational definitions . Methods N = 681 volunteers ( 48 % female ; mean ± SD age 61.4 ± 7.0 years ) participated in baseline and follow-up assessment s ( mean 5.1 ± 0.5 years later ) . Appendicular lean mass ( ALM ) was assessed by dual-energy X-ray absorptiometry , h and grip ( HGS ) and lower-limb ( LLS ) strength were assessed by dynamometry , and falls risk was determined using the physiological profile assessment . Anthropometric definitions ( ALM/height squared [ ALM – H ] , ALM/weight × 100 and a residuals method [ ALM – R ] ) and performance-based definitions ( HGS , LLS and upper- and lower-limb muscle quality [ LMQ ] ) of sarcopenia were examined . The lowest 20 % of the sex-specific distribution for each definition at baseline was classified as sarcopenia . Results Sarcopenia prevalence increased after 5 years for all operational definitions except ALM – H ( men : −4.0 % ; women : −5.5 % ) . Men classified with sarcopenia according to anthropometric definitions , and women classified with sarcopenia according to performance-based definitions , had significant increases in falls risk over 5 years ( all P < 0.05 ) compared to individuals without sarcopenia . Significant sex interactions were observed for ALM-R , LLS and LMQ ( all P < 0.05 ) definitions . Conclusions Sarcopenia prevalence generally increases at a higher rate when assessed using performance-based definitions . Sarcopenia is associated with increases in falls risk over 5 years in community-dwelling middle-aged and older adults , but sex-specific differences may exist according to different anthropometric or performance-based definitions Background Sarcopenia is characterized by decreased skeletal muscle plus low muscle strength and /or physical performance . This study was performed to determine the association of sarcopenia with short-term postoperative outcomes after gastrectomy for gastric cancer . Methods We conducted a prospect i ve study of 255 consecutive patients with gastric cancer who underwent curative gastrectomy .  The sarcopenia elements , including lumbar skeletal muscle index , h and grip strength , and gait speed , were measured before surgery . Patients were followed up after gastrectomy to gain the actual clinical outcomes . Factors contributing to postoperative complications were analyzed by univariate and multivariate analysis . Results Sarcopenia was present in 32 of 255 patients ( 12.5 % ) , and was significantly correlated with advance age , lower body mass index , higher nutritional risk screening ( NRS ) 2002 score , and lower preoperative serum albumin and hemoglobin . Compared with non-sarcopenic patients , sarcopenic patients had a higher risk of postoperative complications , longer postoperative hospital stay , and more hospital costs . In univariate analysis , sarcopenia ( p < 0.001 ) , nutritional risk ( NRS 2002 score ≥3 ; p = 0.003 ) , advanced age ( ≥75 years ; p = 0.014 ) , anemia ( p = 0.012 ) , hypoalbuminemia ( p = 0.029 ) , and diabetes ( p = 0.014 ) were associated with postoperative complications . Multivariable analysis revealed that sarcopenia ( p < 0.001 ) and diabetes ( p = 0.006 ) were independent predictors of postoperative complications . Conclusions Sarcopenia is an independent predictor of postoperative complications in patients with gastric cancer after gastrectomy To determine the prevalence of low skeletal muscle mass in patients undergoing transcatheter aortic valve replacement ( TAVR )  and whether skeletal muscle mass measured from preoperative computed tomography ( CT ) images provides value in predicting postoperative length of stay ( LOS ) . BACKGROUND There are limited data on the use of body composition as a frailty measure in TAVR patients and no studies have determined if this measure predicts LOS . METHODS We studied 104 consecutive patients who underwent TAVR at Tallahassee Memorial Hospital from 2012 to 2016 . Patient demographics , st and ard frailty measures ( h and grip , albumin , and 5-m walk test ) , clinical comorbidities , echocardiographic data , and Valve Academic Research Consortium II major complications were recorded prospect ively . Skeletal muscle index ( SMI ) [ skeletal muscle mass cross-sectional area at L3/height2 ] was measured from CT images using Slice-O-Matic software ( Tomovision , Montreal , Quebec , Canada ) . Clinical outcomes were assessed and multivariate methods used to determine predictors of LOS . RESULTS Sarcopenia was prevalent in men ( 83 % ) and women ( 56 % ) . Patients who suffered from a major complication had significantly longer length of stay ( 13 vs 4.6days , P<.0001 ) . Skeletal muscle index correlated with age , sex , body mass index , h and grip strength , and previous coronary artery bypass graft surgery , but not major complications . A multivariate model including all univariate predictors of LOS showed SMI , major complications , transapical access , atrial fibrillation , and chronic obstructive pulmonary syndrome as independent predictors of LOS . For every 14-cm2/m2 increase in SMI , there was a 1-day reduction in LOS . None of the st and ard measures of frailty predicted LOS . CONCLUSIONS Skeletal muscle index , a measure of sarcopenia readily determined from pre-TAVR CT scans , independently predicts TAVR LOS better than st and ard frailty testing . Further evaluation of SMI as a frailty measure after TAVR and other cardiovascular procedures is warranted BACKGROUND Age-related losses of muscle mass , strength , and function ( sarcopenia ) pose significant threats to physical performance , independence , and quality of life . Nutritional supplementation could positively influence aspects of sarcopenia and thereby prevent mobility disability . OBJECTIVE To test the hypothesis that a specific oral nutritional supplement can result in improvements in measures of sarcopenia . DESIGN A multicenter , r and omized , controlled , double-blind , 2 parallel-group trial among 380 sarcopenic primarily independent-living older adults with Short Physical Performance Battery ( SPPB ; 0 - 12 ) scores between 4 and 9 , and a low skeletal muscle mass index . The active group ( n = 184 ) received a vitamin D and leucine-enriched whey protein nutritional supplement to consume twice daily for 13 weeks . The control group ( n = 196 ) received an iso-caloric control product to consume twice daily for 13 weeks . Primary outcomes of h and grip strength and SPPB score , and secondary outcomes of chair-st and test , gait speed , balance score , and appendicular muscle mass ( by DXA ) were measured at baseline , week 7 , and week 13 of the intervention . RESULTS H and grip strength and SPPB improved in both groups without significant between-group differences . The active group improved more in the chair-st and test compared with the control group , between-group effect ( 95 % confidence interval ) : -1.01 seconds ( -1.77 to -0.19 ) , P = .018 . The active group gained more appendicular muscle mass than the control group , between-group effect : 0.17 kg ( 0.004 - 0.338 ) , P = .045 . CONCLUSIONS This 13-week intervention of a vitamin D and leucine-enriched whey protein oral nutritional supplement result ed in improvements in muscle mass and lower-extremity function among sarcopenic older adults . This study shows proof-of-principle that specific nutritional supplementation alone might benefit geriatric patients , especially relevant for those who are unable to exercise . These results warrant further investigations into the role of a specific nutritional supplement as part of a multimodal approach to prevent adverse outcomes among older adults at risk for disability
There is a lack of robust evidence to assess the strength of other treatment options
Objectives Sarcopenia , defined as an age-associated loss of skeletal muscle function and muscle mass , occurs in approximately 6 - 22 % of older adults .
