Conclusion The prevalence of sarcopenia depends mostly on the diagnostic cut-off points of different criteria .
Preoperative sarcopenia is a risk factor for both long-term and short-term outcomes
Background The impact of sarcopenia on the outcome of gastrointestinal ( GI ) oncological patients is still controversial .
We aim to discuss the prevalence of sarcopenia and its relation to the oncological outcome .
Development of a simple screening test for sarcopenia in older adults.
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
