Abstract
OBJECTIVE The prevalence of obesity by fat percentage has seen a steady increase in older adults in recent years, secondary to increases in fat mass in body composition, even in healthy aging. Malnutrition is a common geriatric syndrome with serious clinical outcomes. Increases in fat mass and waist circumference with healthy aging should not prevent the risk of malnutrition from being masked. Malnutrition is often ignored in obese older people due to low BMI cut-off values in many screening tests. The present study seeks to raise awareness of the need to assess the frequency of undernutrition and related factors in obese older adults. METHODS The data of 2013 community-dwelling patients aged ≥ 60 years who applied to a university geriatrics outpatient clinic between April 2012 and November 2022 were analyzed retrospectively, of which 296 were found to be obese based on fat percentage and were included in the study. Demographic data and the presence of any geriatric syndromes were obtained retrospectively from the patient files, functional status was assessed using the KATZ Activities of Daily Living (ADL) Scale and the LAWTON-BRODY Instrumental Activities of Daily Living Scale (IADL); frailty was screened using FRAIL-scale; and the sample was assessed for malnutrition using the Mini Nutritional Assessment-Short Form (MNA-SF), with undernutrition defined as an MNA-SF score of [Formula: see text] The patients' fat percentage and weight were measured using a bioimpedance analyzer. Fatty obesity was defined using the Zoico methodology (fat percentage [Formula: see text] 27.3% for males, [Formula: see text] 40.7% for females)[Formula: see text] handgrip strength (HGS) was measured using a hand dynamometer, and probable sarcopenia was defined as low HGS based on regional cut-off values (35 kg for males, 20 kg for females). RESULTS The mean age of the 296 fatty obese older adults (102 males/194 females) was 74.4 + 6.5 years, and the median fat was 42.2% (27.4-59.5). Undernutrition was detected in 19.6% of the patients based on MNA-SF screening. A univariate analysis revealed age, sex, educational status, daily physical activity status, depression, difficulty in swallowing, chewing difficulty, probable sarcopenia, number of chronic diseases, and IADL to be associated with undernutrition, while a multivariate logistic regression analysis revealed depression [OR = 3.662, 95% CI (1.448-9.013), p = 0.005] and daily physical activity status [OR:0.601, 95% CI (0.417-0.867), p = 0.006] to be independently associated with malnutrition in obese older adults based on fat percentage. CONCLUSION The present study clarifies the significance of undernutrition in obese older adults also in our country, and recommends undernutrition screening to be carried out, by fat percentage, on obese older adults, especially with depression and low daily physical activity.

Abstract
OBJECTIVE While the literature contains several studies on the frailty assessed during hospitalization and/or outpatient settings and nursing homes, few studies have assessed frailty in community-dwelling older adults. We investigated the prevalence of frailty and associated factors among older adults in a sample of community-dwelling older adults. METHODS We included community-dwelling older adults >60 years living in the Fatih District of the Istanbul Province. We conducted the study between November 2014 and May 2015. We collected the data such as age, sex, number of diseases and drugs, functional status, frailty, the presence of geriatric syndromes, common diseases, and quality-of-life assessment. Frailty was evaluated by the FRAIL scale. RESULTS A total of 204 adults (mean age: 75.4±7.3 years) were included, of whom 30.4% were robust, 42.6% were pre-frail, and 27% were frail. In multivariate analyses, associated factors of frailty were the number of drugs [odds ratio (OR)=1.240, p=0.036], the presence of cognitive impairment (OR=0.300, p=0.016), and falls (OR=1.984, p=0.048). CONCLUSION The present study established the prevalence of frailty in a large district in the largest metropolis in the country through a valid screening method. Our results suggest that clinicians should consider frailty evaluation in patients with multiple drug usage, cognitive impairment, and falls.

Abstract
BACKGROUND & AIMS Sarcopenia is a well-defined geriatric syndrome and a major cause of disability and mortality. We investigate the associations of alternative sarcopenia definitions with mortality in community-dwelling older adults. METHODS Sarcopenia was defined based on the EWGSOP1 and EWGSOP2 probable sarcopenia criteria, with standard handgrip strength (HGS) cut-offs of 30/20 kg for an EWGSOP1 definition and 27/16 kg for an EWGSOP2 definition, or alternatively, population-specific cut-offs of 35/20 kg for a EWGSOP2 definition. The 5-year mortality rate was assessed in the accessible cases. RESULTS The prevalence of sarcopenia among 204 older adults [53.9% female; aged 74.5 ± 7.0] was 4.9% based on the EWGSOP1 criterion, 23.5% according to the EWGSOP2-suggested standard (British) HGS cut-offs and 50.0% based on the EWGSOP2 population-specific cut-offs. In the 103 accessible patients, the mortality rate was 30.1%. Cox-regression analyses adjusted for parameters determined through univariate analyses [age and sarcopenia definitions (in 3 different models)], showed that the EWGSOP1 definition (HR = 4.26, 95% CI = 1.45-12.42, p = 0.008) and EWGSOP2 probable sarcopenia definition with population-specific cut-offs (HR = 2.58, 95% CI = 1.12-5.93, p = 0.03) were associated with a greater mortality risk, while the EWGSOP2 probable sarcopenia definition with standard-cut offs was not (p = 0.09). CONCLUSIONS This is the first study to investigate the associations of EWGSOP2-defined probable sarcopenia with mortality based on standard vs. population-specific HGS cut-offs. The results suggest that population-specific cut-offs should be used when available. We suggest that conducted in community-dwelling older adults, our results have implications for most of older adults.

Abstract
INTRODUCTION Sarcopenia is a prevalent disorder in older adults with significant adverse outcomes and regular screening is recommended for those at risk. The SARC-F questionnaire is the most commonly recommended screening tool for sarcopenia. However, as a self-reported tool, it cannot be applied to dependent individuals with communication problems. We hypothesized that implementation of the proxy-reported SARC-F (SARC-F by proxy) would be non-inferior in screening sarcopenia when compared with the standard SARC-F. Thus, we aimed to investigate the clinical validity of the SARC-F by proxy in identifying sarcopenia in older adults and to compare its performance with the standard SARC-F. Additionally, we aimed to determine the ideal cut-off of SARC-F by proxy in screening sarcopenia. MATERIALS AND METHODS This is a validation study including older adults aged ≥60 years without communication problems and their close proxies. The participants were recruited from a geriatric outpatient clinic of a tertiary health center and a nursing home. Standard SARC-F was transformed to SARC-F by proxy and administered to the proxies of older adults, and standard SARC-F was administered to the patients simultaneously in different rooms. We defined sarcopenia as probable and confirmed by the EWGSOP2 consensus report. We performed receiver operating characteristics (ROC) and sensitivity/specificity analyses of SARC-F by proxy for diagnosing sarcopenia and compared its performance with standard SARC-F by the DeLong test. RESULTS We included 172 older adults (median age: 72; 44.8% female) and 107 proxies in close contact (median age: 55, 63.2% female). The prevalence of probable and confirmed sarcopenia was 18.9% and 12.9%, respectively. For both definitions, area under the curve (AUC) values of SARC-F by proxy and standard SARC-F were moderate and similar [probable sarcopenia: 0.619 and 0.624 (p = 0.9); confirmed sarcopenia 0.613 and 0.645 (p = 0.7), respectively]. The best balance between sensitivity and specificity was achieved with a SARC-F by proxy score of ≥2 for both sarcopenia definitions (sensitivity levels were 74.7% and 77.8%, and specificity levels were 50.0% and 49.6%, for probable and confirmed sarcopenia, respectively). DISCUSSION SARC-F by proxy showed a similar, non-inferior performance compared to the standard SARC-F in the evaluation of sarcopenia. Our results suggest that it can be used instead of standard SARC-F to screen sarcopenia in older patients with communication problems. Further validation studies in different populations are warranted to support our findings.

Abstract
OBJECTIVE Probable sarcopenia is a predictor of functional limitation in older adults. However, whether standard thresholds recommended by guides, or population-specific thresholds better predict impairment in functionality is an issue that needs to be enlightened. We aimed to study the associations of probable sarcopenia identified by the use of EWGSOP2 and population-specific thresholds with deterioration in functionality at follow-up and give prevalences of probable sarcopenia with different thresholds in older outpatients admitted to a tertiary health center. METHODS In this retrospective, longitudinal follow-up study, we assessed handgrip strength (HGS) at the admission with a Jamar hand-dynamometer and diagnosed probable sarcopenia with standard and population-specific thresholds, i.e., 27 kg/16 kg, and 35 kg/20 kg in males/females, respectively. We evaluated activities of daily living (ADL) and instrumental ADL (IADL), with Katz and Lawton scales, at the admission and follow-up. To study whether probable sarcopenia was a predictor of impaired functionality, we defined two models for Cox regression analysis. We performed adjustments for age, sex, and nutritional status (assessed by Mini-Nutritional Assessment-Short Form) in Model 1 and defined Model 2 by adding low gait speed and frailty to the variables in Model 1. RESULTS Among a total of 1970 patients, 195 had follow-up of median 560 days. The mean age was 75.5 ± 5.5, and 142 (72.8%) were female. In the basal evaluation, the prevalences of probable sarcopenia defined by the standard cut-offs and by population-specific cut-offs were 8.7% and 35.4%, respectively. In univariate analyses (Kaplan-Meier log-rank test), probable sarcopenia by population-specific cut-offs, but not EWGSOP2-cut-offs, was associated with deteriorations in both ADL (p = 0.04) and IADL (p < 0.001). In multivariate analyses, only the probable sarcopenia identified by population-specific cut-offs was independently associated with impairment in IADL in both models [HR (95%CI) = 1.88 (1.07-3.30), and 1.9 (1.04-3.6); for Model 1 and Model 2, respectively)]. CONCLUSION Our findings suggested that the definition of probable sarcopenia identified by not standard, but population-specific thresholds more reliably predicted longitudinal deterioration of functionality in older outpatients. This finding might be considered as evidence supporting the use of population-specific cut-offs when the concern is sarcopenia diagnosis.

Abstract
PURPOSE Falls are a common public health problem in older adults regarding increased morbidity, mortality, and healthcare costs. Determining the factors associated with falls is of utmost importance for detecting at-risk people. We present a field study conducted to examine the prevalence of falls and the associated factors among community-dwelling older adults. METHODS In this population-based cross-sectional study, we included adults aged >60 years living in the Fatih District of the Istanbul Province between November 2014-May 2015, through a simple random sampling method. We noted age, sex, falls, fear of falling, number of diseases and medications, the presence of diabetes, hypertension, dyslipidemia, urinary and fecal incontinence, and chronic pain. Frailty was assessed with the FRAIL questionnaire. Functional capacity was evaluated by Katz's 6-item ADL and Lawton Brody's 8-item IADL scales. The European quality-5 dimension (EQ-5D) questionnaire was used for the quality of life assessment. The cognitive status screening was conducted with a Mini-cog test. Depressive mood was evaluated with the Geriatric Depression scale short form (GDS-SF). Malnutrition screening was conducted by the mini-nutritional assessment short form. Handgrip strength (HGS) was measured with a hand dynamometer. Body composition was assessed through a bioimpedance analysis. The 4-meter usual gait speed was recorded. The European Working Group on Sarcopenia in Older People2 (EWSGOP2) criteria was used for the sarcopenia definition. The Romberg and the postural instability tests were evaluated for balance and gait. Continuous variables were expressed as mean±standard deviation or median and interquartile range for descriptive statistics, while categorical variables were expressed as the number and percentages. The differences between groups were determined through an independent sample t-test or Mann-Whitney U test when required. Chi-square and Fisher's exact tests were applied for categorical variables. A multivariate logistic regression analysis was used to determine the independent factors associated with falls among the factors identified as significant in univariate analyses. RESULTS The prevalence of falls was 28.5% [mean age: 75.4±7.3 (range: 61-101 years), 53.6% female], and a significant association was identified between falls and the number of diseases and medications, diabetes, chronic pain, frailty, ADL, IADL, and EQ-5D scores, dementia, GDS-SF score and level of ambulation in univariate analyses (p=0.001, 0.030, 0.030, 0.010, 0.004, 0.040, 0.007, 0.003, 0.030 and 0.007, respectively). In the multivariate analysis, positive dementia (OR=3.66, 95% CI=1.40-9.53; p=0.010) and frailty screenings (OR =1.47, 95% CI=1.05-2.06; p=0.020) were identified as associates of falls. CONCLUSION Falls were independently associated with positive dementia and frailty screening. These results will help develop specific and tailored precautions for at-risk groups to prevent the negative outcomes of falls.

Abstract
BACKGROUND & AIMS Ageing brings alterations in body composition, as skeletal muscle gradually declines and accumulation of adipose tissue accompanies it. Although sarcopenia (S) and obesity (O) were separately reported to be associated with frailty and poor physical performance, whether they bring more detrimental or favorable effect when they coexist (i.e. sarcopenic obesity; SO) is an issue needs clarification. We aimed to study the associations of SO and S alone with frailty and poor physical performance, by using probable S definition. METHODS This was a retrospective, cross-sectional study including community dwelling older adults who were ≥60 years old and admitted to the outpatient clinic of a tertiary hospital between 2012 and 2020. We measured handgrip strength via hand dynamometer and defined decreased muscle strength as probable S. We performed bioimpedance analysis to evaluate body composition and used fat percentile method to define obesity. We assessed nutritional status via Mini-Nutritional Assessment-Short Form, frailty via FRAIL scale, and physical performance via Timed Up and Go (TUG) test. We examined the associations of four body phenotypes, i.e. non-S non-O, SO, S alone and O alone with frailty and impaired TUG in univariate and multivariate analyses (Model 1). We further performed a head to head analysis of SO vs S to see if one of them was associated more with frailty and impaired TUG (Model 2). RESULTS There were 1366 older adults included in the study (mean age: 74.6 ± 6.9; 68.3% female). The prevalences of non-S non-O, S alone, SO and O alone were 53.5, 7.5, 2.8 and 36.2%, respectively. Multivariate analysis adjusted for age, gender and nutritional status revealed that both SO and S alone were independently associated with frailty and impaired TUG, with SO demonstrating lower odds than S alone (OR = 5.9 and 6.05 for frailty, and 3.9 and 4.4 for TUG, respectively). Head-to-head comparison between SO and S alone in Model 2 showed that two groups did not demonstrate significant difference in terms of the frailty and impaired TUG risk. CONCLUSION Although SO and S groups demonstrated similar risks, obesity accompanying sarcopenia might show a favorable trend in terms of frailty and poor physical performance, compared to sarcopenia alone. Longitudinal studies are needed to reveal whether an obesity paradox exists for frailty and physical performance in older adults.

Abstract
BACKGROUND The sarcopenia quality-of-life (SarQoL)® questionnaire is a multidimensional sarcopenia specific tool designed for community dwelling older adults. AIMS The aim of this study was to translate, to cross-culturally adapt and validate the SarQoL® questionnaire to assess sarcopenia-related quality of life in Turkish older adults. METHODS The validation process was performed in two sections: the first section constituted the translation with cross-cultural adaptation of SarQoL® into Turkish. Second section constituted the clinical validation study. To validate the Turkish version of the SarQoL®, we assessed its validity (discriminative power, construct validity), reliability (internal consistency, test-retest reliability) and floor/ceiling effects. RESULTS One hundred community-dwelling subjects (mean age: 74.7 ± 6.1 years) were evaluated. The EWGSOP2 consensus diagnostic criteria were used to diagnose probable sarcopenia. A database including 1437 older adults, with complete evaluation of sarcopenia parameters, served to define low global muscle function. Results revealed a good discriminative power: subjects with probable sarcopenia had higher total scores compared to non-sarcopenic subjects (50 ± 16 vs. 68.9 ± 16.9, p < 0.001) a high internal consistency (Cronbach's alpha: 0.88), consistent construct validity and excellent test-retest reliability (intraclass correlation coefficient: 0.97, 95% confidence interval: 0.94-0.98). There was no floor/ceiling effect. CONCLUSION The Turkish version of the SaQoL® questionnaire was found to be reliable and valid for the measurement of quality of life of sarcopenic patients and is, therefore, available for use in clinical research and practice. This validation could enable use of the SarQoL® tool in the eastern populations more confidently.

Abstract
OBJECTIVES A preserved ambulation is one of the keypoints for functionality and polypharmacy, a common problem in older adults, is associated with worse functional status. Our aim was to examine the associations of polypharmacy with certain physical performance measures used to evaluate ambulation. METHODS This retrospective, cross-sectional study was conducted in a geriatric outpatient clinic. Using ≥5 medications was accepted as polypharmacy. Usual gait speed (UGS), chair sit-to-stand test (CSST), timed up and go test (TUG) and short physical performance battery (SPPB) were performed to assess physical performance status. We created two models for logistic regression analyses: Model 1 was adjusted for age, sex and body mass index (BMI). We added comorbidities to Model 1 and further created Model 2. RESULTS There were 392 participants (69.1% were female, mean age: 73.9±6.2 years). Polypharmacy was seen in 62.5%. Participants with polypharmacy presented with a poor physical performance compared to the no-polypharmacy group (p<0.001, for each). In multivariate analyses, polypharmacy was independently associated with poor SPPB (Odds Ratio (OR)=2.5; 95% Confidence Interval (CI)=1.3-4.7 and OR=2.4; 95% CI=1.2-4.8 for Model 1 and 2, respectively) and long CSST (OR= 2.6; 95% CI=1.3-5.2 and OR=3.7; 95% CI=1.7-8.2 for Model 1 and 2, respectively). There was a significant association between polypharmacy and slow UGS in Model 1 (OR=1.9; 95% CI=1.0-3.5); but relationship did not persist after adding comorbidities into the first model (OR=1.6; 95% CI= 0.8-3.1). There was no significant association between long TUG and polypharmacy in any of the models. CONCLUSION Polypharmacy is well-known with its association with falls and fractures in older adults and this might be explained by its association with poor physical performance. Whether polypharmacy causes a deterioration in physical performance is an issue needs to be enlightened by further longitudinal studies.

Abstract
BACKGROUND & AIMS There have been several attempts to come up with a global operational definition of sarcopenia (S), and consequently, a definition of S has been established, to some extent. That said, the definition of sarcopenic obesity (SO), which is defined as the presence of obesity + sarcopenia, remains obscure, hindering evaluations of the prevalence and relevance of SO. It has yet to be elucidated whether SO is associated with worse functionality when compared to S alone (S without obesity). In the present study, we compare SO and S alone in terms of their associations with functional measures through the application of alternative definitions of SO. As a secondary output, we document the prevalence of SO based on alternative definitions. METHODS This retrospective cross-sectional study included community-dwelling adults over 60 years of age who presented as outpatients to a university hospital between 2012 and 2020. All were evaluated for body composition (bioimpedance analysis), handgrip strength (Jamar hand dynamometer) and functional health status [activities of daily living (ADL), instrumental activities of daily living (IADL)]. The fat percentile method was used to define the obesity component of SO. Low muscle mass (LMM) was defined using two different adjustment methods of skeletal muscle mass (LMM adjusted by height2 or LMM adjusted by BMI). S was defined based on the EWGSOP2 definition, as probable S (low muscle strength) or confirmed S (low muscle strength + LMM). Accordingly, three alternative definitions of SO were applied based on three alternative definitions of S, i.e., "obesity + sarcopenia (probable)", "obesity + sarcopenia (confirmed, LMM adjusted by height2)" and "obesity + sarcopenia (confirmed, LMM adjusted by BMI)". The associations of SO and S alone with functional measures were examined with univariate analyses and adjusted multivariate analyses. RESULTS Included in the study were 1468 older adults (median age 75; 68.8% female). The prevalence of SO was very low (0.2%) based on the SO definition "obesity + sarcopenia (confirmed, LMM adjusted by height2), but it was present at a considerable and comparable rate based on SO definition "obesity + sarcopenia (probable)" and SO definition "obesity + sarcopenia (confirmed, LMM adjusted by BMI)" (4.1%, 4.0%; respectively). As SO by "obesity + sarcopenia (confirmed, LMM adjusted by height2)" had an ignorable prevalence, this definition of SO was excluded from further analyses. Multivariate analyses revealed that, when compared to the Non-S Non-Obese group, S alone definitions had odds ratio (OR) of 5.4 and 3.4 while SO definitions had an OR of 3.2 and 2.7 for impaired ADL, and an OR of 7.9 and 6.4, while SO definitions had an OR of 3.0 and 2.7 for impaired IADL. SO was thus found to be associated with a lower prevalence of impaired functional measures than that of S alone. CONCLUSIONS Our results suggest that the SO definition confirmed, LMM adjusted by height2 has an ignorable prevalence in populations in which underweight or malnutrition is uncommon. Among sarcopenic older individuals, obesity may have a protective effect against the limitations of some functional measures, providing evidence of the possible protective effect of obesity in sarcopenic individuals.

Abstract
BACKGROUND/OBJECTIVE In 2018 EWGSOP2 has suggested low muscle strength as the primary parameter of sarcopenia. The consensus has recommended SARC-F questionnaire as a screening test to find cases with low muscle strength which has been designated as probable sarcopenia. We aimed to study the ability of SARC-F to find probable sarcopenia cases in older patients. DESIGN Retrospective, cross-sectional. SETTING Istanbul University Istanbul Faculty of Medicine. PARTICIPANTS A total of 456 older adults (71.1% female, mean age: 74.6±6.6 years). MEASUREMENTS We diagnosed probable sarcopenia by EWGSOP 2 criteria, i.e., presence of low handgrip strength (HGS). SARC-F questionnaire was performed by all participants. We used a receiver operating characteristics curve to obtain SARC-F cut-off values to detect probable sarcopenia and calculated the area under the curve and 95% confidence interval (CI). RESULTS We included 456 participants (71.1% female; mean age: 74.6 ± 6.6 years). Probable sarcopenia was present in 58 (12.7%). SARC-F cut-off ≥ 2 presented the best balance between sensitivity and specificity (sensitivity: 64.9% vs specificity: 67.9%) to detect probable sarcopenia [the area under the receiver operating characteristics curve (AUC) = 0.710; 95% Cl: 0.660-0.752, p< 0.001]. SARC-F with a cut-off point ≥ 1 had sensitivity 84.2% and specificity 40.5% and SARC-F ≥ 4 had high specificity 88.2% with 40.3% sensitivity. CONCLUSION SARC-F is a good screening tool for sarcopenia in practice. Our findings suggest SARC-F ≥ 1 cut-off point to be used as the probable sarcopenia screening tool regarding its high sensitivity. Consequently, SARC-F ≥ 4 cut-off is better to be used if one prefers to exclude probable sarcopenia.

Abstract
BACKGROUND/OBJECTIVES The physical phenotype of frailty, described by Fried et al., shows significant overlap with sarcopenia. EWGSOP2 recommends the SARC-F questionnaire to screen for sarcopenia. Considering common features between both conditions, we aimed to investigate whether the SARC-F questionnaire could also be a valid and reliable tool to screen or evaluate frailty. DESIGN Retrospective, cross-sectional. SETTING Istanbul University Istanbul Faculty of Medicine. PARTICIPANTS A total of 447 older adults (70.7% female, mean age: 74.5±6.6 years). MEASUREMENTS Frailty was assessed by the modified Fried scale. SARC-F questionnaire was performed by all participants. We used a receiver operating characteristics curve to obtain SARC-F cut-off values to detect frailty, and calculated the area under the curve and 95% confidence interval. RESULTS There were 93 (20.8%) older adults with frailty according to the modified Fried scale. SARC-F cut-off ≥1 had 91.4% sensitivity and 44.9% specificity. SARC-F cut-off ≥2 presented the best balance between sensitivity and specificity (sensitivity: 74.1% vs. specificity: 73.7%) to identify frailty (area under curve: 0.807; 95% confidence interval: 0.76-0.84, p<0.001). SARC-F ≥4 had high specificity of 92.6% with a sensitivity of 46.2%. CONCLUSION We suggest that SARC-F ≥1 point can be used to screen for frailty with high sensitivity, and SARC-F ≥4 can be used to diagnose frailty with high specificity. SARC-F may be used to evaluate frailty in usual geriatric practice.

Abstract
BACKGROUND/OBJECTIVE While assessment of sarcopenia has drawn much attention, assessment of low muscle power has not been studied widely. This is, to a large extend, due to a more difficult assessment of power in practice. We aimed to compare the associations of low power and sarcopenia with functional and performance measures. MATERIAL AND METHODS We designed a retrospective and cross-sectional study. Community-dwelling outpatient older adults applied to a university hospital between 2012 and 2020 composed the population. We estimated body composition by bioimpedance analysis. Other measures were handgrip strength, timed-up-and-go-test (TUG), usual gait speed (UGS), activities of daily living (ADL) and instrumental activities of daily living (IADL) tests. We assessed muscle power by a practical equation using a 5-repetition sit-to-stand power test. We adjusted the power by body weight and defined low muscle power threshold as the lowest sex-specific tertile. We noted demographic characteristics, number of medications, and diseases. We defined sarcopenia by EWGSOP2 definition. RESULTS Cut points for low relative muscle power were <2.684 and <1.962 W/kg in males and females, respectively. Low muscle power was related with both measures of disability (impaired ADL and IADL) (OR=2.4, 95% CI= 1.4-4.0, p=0.001; OR=2.4, 95% CI= 1.4-4.1, p=0.001; respectively). Low muscle strength (i.e. probable sarcopenia) was only related with disability in IADL (OR=3.6, 95% CI= 1.6-8.; p=0.002); confirmed sarcopenia was related with neither measures. Low muscle power was not related with impaired TUG (p=1) but with impaired UGS (OR=6.6, 95% CI= 3.6-11.0; p<0.001). Probable sarcopenia was not related with impaired TUG (p=0.08) but with impaired UGS (OR=2.4, 95% CI= 1.1-5.3; p=0.03) and confirmed sarcopenia was related with neither measures (p=1, p=0.3; respectively). CONCLUSION Low muscle power detected by simple and practically applicable CSST (Chair Sit To-Stand Test) power test was a convenient measure associated with functional and performance measures. It was related to functionality and performance measures more than sarcopenia. Future longitudinal studies are needed to examine whether it predicts future impairment in ADL, IADL, and performance measures.

Abstract
PURPOSE Sarcopenic-obesity (SO) is associated with low-functional-status and mortality. Few studies evaluated the definition and prevalence of SO. We aimed to investigate the fat-percentage cut-off values for obesity and prevalences of obesity, SO in community-dwelling older adults in Turkey. METHODS Body-composition was measured using bioimpedance-analysis. Sarcopenia was defined by European-Working-Group-on-Sarcopenia-in-Older-People criteria. Obesity was defined by two different methods, a fat-percentile above 60th percentile (Zoico-method) or a BMI of ≥30 kg/m2 (WHO-definition). RESULTS We enrolled 992 subjects (308 men, 684 women). Body fat-percentage thresholds for obesity were 27.3% for men and 40.7% for women according to Zoico-method. The rates of obesity were about 40% in both genders by Zoico-method; 29.2% versus 53.7% for men and women by WHO definition. Prevalences-of-sarcopenia was 3.1% versus 0.4%; SO was 0.3% versus 0.1% when obesity was assessed with Zoico-method in men and women, respectively. No case of SO was defined when obesity was assessed using WHO-definition. CONCLUSION The threshold for obesity definition according to Zoico-method was similar to other European-populations. While obesity-prevalences were considerably high, SO prevalences were low but comparable to other populations. This low-prevalence seems to be due to underestimation of sarcopenia in obese subjects when skeletal-muscle-mass was adjusted by height2 to recognize low-muscle-mass.

Abstract
OBJECTIVE We aimed to compare European Working Group on Sarcopenia in Older People (EWGSOP2)-suggested and population-specific handgrip strength (HGS) thresholds to detect probable sarcopenia and their associations with physical-performance measures and frailty. METHODS A retrospective cross-sectional observational-study included geriatrics outpatients applied to a university-hospital. HGS, timed up and go test (TUG), and usual gait speed (UGS) were assessed. Frailty was screened by FRAIL-scale. RESULTS A total of 1825 older adults were included (mean age, 74.5 + 7.0 years; 68.8% female). Prevalence of low-HGS were 12.2% by the EWGSOP2-recommended (27/16 kg) cut-offs and 37.5% by population-specific cut-offs (35/20 kg) (p<.001). When low-HGS was defined by EWGSOP2 suggested cut-offs, low-HGS was associated with impaired UGS, (odds ratio [OR] = 3.8, 95% confidence interval [CI]: 2.0-6.9, p<.001); impaired TUG, (OR = 4.6, 95% CI: 2.4-8.8, p<.001); and frailty (OR = 20.9, 95% CI: 8.3-53.0, p<.001). Similarly, low HGS determined by population-specific cut-off points was associated with impaired UGS (OR = 3.1, 95% CI: 2.1-6.9, p<.001); impaired TUG (OR = 6.0, 95% CI: 3.0-11.8, p<.001); and frailty (OR = 7.3, 95% CI: 4.1-13.0, p<.001). CONCLUSIONS Application of EWGSOP2-recommended standard HGS-cut-offs showed successful application in-practice. However, use of standard HGS cut-offs may result in underdiagnosis of probable sarcopenia. Therefore, we suggest that, whenever available, use of population-specific cut-offs for HGS may be better for correctly identifying older adults at risk.

Abstract
AIM Sarcopenia is recognized with its adverse functional outcomes. We aimed to report the prevalence of European Working Group on Sarcopenia in Older People (EWGSOP) defined sarcopenia and its individual components in community dwelling outpatient older adults and study the correlations of EWGSOP defined sarcopenia, muscle mass, muscle strength, and physical performance with functional status. MATERIAL AND METHODS The subjects were prospectively recruited from the geriatrics outpatient clinics of our university hospital. Body composition was assessed with bioimpedance analysis. Muscle strength was assessed by measurement of hand grip strength with hydraulic hand dynamometer, physical performance was assessed by 4 meter usual gait speed (UGS). Impaired muscle function was defined as presence of low muscle strength and or slow gait speed. As a measure of functionality, modified version of Katz activities of daily living (ADL) and Lawton instrumental activities of daily living (IADL) were assessed. RESULTS A total of 242 community dwelling outpatients with mean age of 79.4 ± 5.7 years were enrolled. 31.8% were male. Prevalence of low muscle mass was 2.1% and impaired muscle function was 71.1%. Prevalence of EWGSOP defined sarcopenia was 0.8% (1.3% in men and 0.6% in women). Most correlated parameter with ADL and IADL was the usual gait speed (r = 0.49, r = 0.63; p < .001, respectively). Grip strength was also correlated with ADL and IADL (r = 0.28, r = 0.35; p < .001). However, the skeletal muscle mass index (SMMI) was not correlated with ADL, IADL (p = .22, p = .22, respectively). In regression analysis, both ADL score and IADL scores were most related to UGS (beta = 0.5 and 0.6, p < .001), age (beta = -0.25 and -0.2, p < .001) and then sarcopenia (beta = 0.1 and 0.1, p < .05) but was not related to hand grip strength or SMMI. CONCLUSIONS The prevalence of sarcopenia was low as 0.8% albeit the presence of impaired muscle function in more than 2/3 of the cases. We have found that EWGSOP defined sarcopenia had association with ADL and IADL. The gait speed component of sarcopenia had the strongest associations with functional measures but SMMI component did not have any relation. We suggest that although low muscle mass may be a parameter related to worse functionality, it should not be regarded prerequisite for presence of sarcopenia analogous to low bone mineral density for osteoporosis.

Abstract
AIM Low muscle mass (LMM) is a prerequisite to define sarcopenia. We aimed to report muscle-mass reference cut-off points adjusted for height and weight as muscle-mass threshold best discriminating muscle-weakness and adjusted for body mass index (BMI) significantly lower than that of healthy young population. MATERIAL AND METHOD We included young adults between 18 and 39 years and community dwelling older adults 60-99 years of age. Bioimpedance analysis (BIA) was used to assess skeletal muscle mass. Skeletal muscle mass index (SMMI) adjusted for height, weight, BMI were calculated [SMMI (height), SMMI (weight), SMMI (BMI)]. Handgrip strength was evaluated with Jamar hydraulic dynamometer for muscle-strength. SMMI (height) and SMMI (weight) cut-offs that predict low muscle-strength were calculated with receiver operator characteristic (ROC) analysis. Low muscle-strength was evaluated by three different thresholds, i.e. 32 kg/22 kg, 30 kg/20 kg, 26 kg/16 kg in males/females. SMMI (BMI) cut-offs were calculated as "mean young SMMI (BMI)-two standard deviation." RESULTS The young and older reference groups included 301 and 992 individuals, respectively. LMM cut-points for SMMI (height) were (i) 10.8 vs. 8.9 kg/m2 for 32/22 kg; 10.8 vs. 9.4 kg/m2 for 30/20 kg and 11.1 vs. 8.9 kg/m2 for the 26/16 kg thresholds, in males and females, respectively. LMM cut-points for the SMMI (weight) were 40.6% and 33.2% for the all three studied muscle-strength thresholds for males and females, respectively. For all the analyses sensitivity, specificity and likelihood ratios were not sufficiently high in both genders. The SMMI (BMI) cut-points were 1.049 vs. 0.823 kg/BMI for males and females, respectively. CONCLUSIONS We presented the very first cut-off thresholds for muscle-mass adjusted by height and weight that best discriminate muscle-weakness in the older adults and by BMI that is significantly lower than that of healthy young population. This study suggests that correlation between total skeletal muscle mass measured by BIA (either adjusted for height or weight) and muscle strength is low.

Abstract
Aim: The rates and reasons why clinicians decide not to follow recommendations from explicit-criteria have been studied scarce. We aimed to compare STOPP version 2 representing one of the most commonly used excplicit tool with the implicit comprehensive geriatric assessment mediated clinical evaluation considered as gold standard.Methods: Two hundred and six (n = 206) outpatients ≥65 years old were included. The study was designed as retrospective, cross-sectional, and randomised. STOPP version 2 criteria were systematically used to assess pre-admission treatments followed by implicit clinical evaluation regarding two questions: Were the STOPP criteria recommendations valid for the individual patient and were there any potentially inappropriate-prescription other than depicted by STOPP version 2 criteria? The underlying reason(s) and associated clinical-features were noted.Results: About 62.6% potentially inappropriate-prescriptions were identified (0.6 per-subject) according to systematic application of STOPP v2 while it was 53.4% (0.5 potentially inappropriate-prescriptions per subject) by clinician's application of STOPP v2. Prevalence of non-compliance was 14.7% in 18 (21.7%) of 83 patients identified by systematic application. Suggestion to stop a drug was not accepted because of need of treatment despite likelihood of anticipated side-effects in about 2/3 and with no-anticipated side-effects in about 1/3 of non-compliances. Not following STOPP v2 was significantly associated with lower functional level. According to clinician's implicit-evaluation, there were an extra 59.2% potentially inappropriate-prescriptions (0.6 per subject) in 80 (38.8%) patients yielding a total of 112.6% potentially inappropriate-prescription.Conclusions: Most of the STOPP v2 directed drug cessations are decided valid by the clinicians. In patients with higher functional dependency, it is likely that they are not followed due to palliation focussed care/patient-family preferences. There may be as much as STOPP v2 identified potentially inappropriate-prescriptions by implicit evaluation in a significant percent of geriatric patients signifying need for comprehensive geriatric evaluation in practice.

Abstract
AIM Low skeletal muscle mass (LMM) is a criterion to define both sarcopenia and malnutrition. Muscle mass varies with gender, height, weight or fat mass, and many indices of adjusted-muscle mass have been proposed. We aimed to find reference cut-off points of the skeletal muscle mass index (SMMI) adjusted for weight and body mass index (BMI) in Turkish population. MATERIALS AND METHODS Adults between 18 and 39 years of age and community-dwelling older adults of 60-99 years of age were included. Body composition was assessed with bioimpedance analysis (BIA). SMMI adjusted for weight and BMI were calculated [SMMI (weight) and SMMI (BMI)]. Muscle strength was assessed by hand-grip-strength with hand dynamometer. SMMI (weight) cut points were calculated from the healthy young adults' data as "mean SMMI-2 standard deviation (SD)". SMMI (BMI) cut points that predict low muscle strength were calculated with ROC analysis. To define low muscle strength, we used three currently suggested low muscle-strength thresholds, i.e., 32 kg/22 kg, 30 kg/20 kg, 26 kg/16 kg in males/females, respectively. RESULTS 301 healthy young adults (187 male, 114 female) and 992 older people (308 male, 684 female) were included. LMM cut points for SMMI (weight) were 37.4% and 33.6% for males and females, respectively. SMMI (BMI) cut points that best predict the low grip-strength for 32 kg/22 kg; 30 kg/20 kg; 26 kg/16 kg thresholds were1.017 kg/BMI and 0.677 kg/BMI; 1.014 kg/BMI and 0.710 kg/BMI; 1.036 kg/BMI and 0.770 kg/BMI for males and females, respectively. CONCLUSIONS Muscle-mass adjustment methods and techniques show diversity among the studies and have impact on the LMM cut-off points. This study presents population specific LMM thresholds for skeletal muscle mass adjusted for weight and BMI aiming to increase and improve the general applicability of the leading sarcopenia consensus definitions.

Abstract
AIM To investigate the muscle mass adjustment technique that best correlates with functional measures. METHODS A cross-sectional study was designed. Community-dwelling older adults aged ≥60 years were assessed for body composition and functional measures between November 2012 and July 2017 in the geriatric outpatient clinic of a university hospital. Body composition was assessed with bioimpedance analysis. Skeletal muscle mass (SMM) was adjusted by height2 , weight or body mass index (BMI). Functional and disability measures included handgrip strength assessed by a Jamar hydraulic hand dynamometer, gait speed by 4-m usual gait speed, frailty by the Fatigue, Resistance, Ambulation, Illnesses and Loss of Weight scale score, activities of daily living (ADL) and instrumental ADL scores. Nutrition was evaluated by the Mini Nutritional Assessment - Short Form. RESULTS A total of 1437 older adults (458 men, 979 women) with a mean age of 74.6 ± 7.0 years were included. The prevalences of low muscle mass were 2.4%, 47.8% and 20.3% when SMM was adjusted by height2 , weight and BMI, respectively. Multivariate analyses adjusted for age, number of diseases, drugs and the Mini Nutritional Assessment - Short Form score revealed that when the SMM was adjusted by BMI, low muscle mass showed better associations with grip strength, gait speed, ADL, instrumental ADL and frailty than the height2 or the weight-adjusted SMM. CONCLUSIONS SMM adjustment by BMI to designate low muscle mass was better associated with functional and disability measures than adjustment by height2 and weight. The present results put forward the SMM index (by BMI) as the best adjustment method for SMM. These findings might be relevant for defining both sarcopenia and malnutrition.

Abstract
Background Recently frailty has drawn significant interest as an important predictor of several clinically relevant outcomes. There is no widely accepted instrument for the assessment of frailty and most of the current ones evaluate only physical features. The Tilburg Frailty Indicator (TFI) is a valid and reliable instrument which enables multidimensional assessment of frailty. We aimed to adapt and evaluate the Turkish version of the TFI. Methods We translated and culturally adapted the English version of the TFI into Turkish using standard guidelines. We enrolled consecutive patients who were 70 years old or older and were admitted to our outpatient geriatrics clinic. We used Cronbach’s alpha values to evaluate the internal consistency and also assessed inter-observer and test–retest variability using intraclass correlation coefficient (ICC). Results The Cronbach’s alpha reliability coefficients of the instrument ranged from 0.65 to 0.72 and item-total correlation ranged between −0.05 and 0.57. There was a good agreement between two assessments (ICC=0.99) and between two observers (ICC=0.99). Conclusion We have shown the reliability of the Turkish version of the TFI as a tool to evaluate frailty in a multidimensional manner among the Turkish outpatient population.

Abstract
OBJECTIVES Dysphagia is described as a geriatric syndrome that occurs more frequently with aging. It is associated with the deterioration in functionality however, it is usually ignored. Frailty is a geriatric syndrome that is recognized more with its well-known adverse consequences. Very recently, dysphagia has been suggested to accompany frailty in older adults. We aimed to investigate the association between dysphagia and frailty in the community dwelling older adults. DESIGN Prospective, cross-sectional study. SETTING Geriatric outpatient clinic. PARTICIPANTS Older adults aged ≥60 years. MEASUREMENTS Dysphagia was evaluated by EAT-10 questionnaire and frailty by FRAIL scale. Handgrip strength (HGS) was evaluated by hand-dynamometer. Gait speed was evaluated by 4-meter usual gait speed (UGS). Nutritional status was assessed by mini-nutritional assessment-short form (MNA-SF). RESULTS 1138 patients were enrolled. Mean age was 74.1±7.3 years. EAT-10 questionnaire was answered by all and FRAIL-scale by 851 subjects. EAT-10 score >15 points was regarded as significant dysphagia risk. The participants with EAT-10>15 points were older when compared to the participants with EAT-10<=15 points (p=0.002). Among participants with EAT-10>15 points, women gender and neurodegenerative diseases were more prevalent (p=0.04, p=0.002; respectively); number of chronic diseases, number of drugs and FRAIL score were higher (p=0.001 for each), and HGS, UGS, MNA-SF scores were lower (p=0.002, p=0.01, p<0.001; respectively). In multivariate analyses, the factors independently associated with presence of EAT-10 score>15 were FRAIL score and the number of drugs. CONCLUSION Dysphagia is associated with frailty irrespective to age, presence of neurodegenerative diseases, number of chronic diseases and drugs. To our knowledge, this is the largest serie in the literature providing data on independent association of dysphagia with frailty.

Abstract
AIM We investigated whether pulling the rectus muscle medially during open appendectomy surgery had any effect on postoperative pain in this study. METHODS This prospective study was performed on patients 6 years and older who were admitted for acute appendicitis. The patients were divided into two groups, open appendectomy was performed by pulling the rectus muscle medially in the first group and splitting the rectus muscle in the second group. Pain was evaluated in both groups at preoperative and 12 and 24 hour postoperative by using a visual analog scale graded. RESULTS The first group consisted of 31 and the second group of 30 patients. The preoperative and 12 and 24 hour postoperative pain evaluation results were 8.25 ± 1.03, 2.96 ± 1.40 and 1.16 ± 0.93 in the first group and 8.36 ± 0.99, 4.90 ± 1.24 and 2.03 ± 1.06 respectively in the second group. There was no statistically significant difference between the two groups for age, gender, inpatient duration and preoperative pain scores while the 12 and 24 hour postoperative pain scores were lower in the first group than the second group. This difference was statistically significant (P<0.05). CONCLUSION Performing the appendectomy by pulling the rectus muscle medially in clinics using open appendectomy will provide a more comfortable postoperative period for the children.

Abstract
BACKGROUND In this study 67 lumbar spinal stenosis in adult patients operated in our clinic in 3 years are aimed to be analysed in terms of clinical and surgical techniques. METHODS Diagnoses were made on the basis of patients' histories and their clinical examinations. RESULTS Average age was 52.16 +/- 8.9 (33-64). 70.1% (47) of patients were females and 29.9% (20) were males. The most frequent neurological symptoms were 71.1% lasque (+) and 56.7% sensory loss. The anterior-posterior diameter was below 11.5 mm in 56.7% of the cases. Partial recovery was observed in the early term of 71.6% the cases. 56.7% of the cases were applied total laminectomy. CONCLUSION Decompressive laminectomy can be performed safely and effectively in patients of with lumbar stenosis.

Abstract
The styloid process is a bony projection, located just anterior to the stylomastoid foramen, the normal length of which is approximately 20-25 mm. Elongation of the process may cause various clinical symptoms such as neck and cervicofacial pain, described as Eagle's syndrome. The present study aimed to determine the mean length of the styloid process on cadavers, panoramic radiographs, and dry skulls, and to investigate the incidence of the elongated styloid process, while assessing the elongation in relation to Eagle's syndrome. When the measurements from the panoramic radiographs were assessed, the mean length of the styloid processes in males and females on the right and left sides were found to be the following: 25.78 + or - 5.68 mm; 22.69 + or - 3.68 mm, 25.80 + or - 5.75 mm; and 22.75 + or - 3.65 mm, respectively. The males had greater styloid process lengths than the females, and the differences in length on both the right and left sides were statistically significant. Descriptive statistics and comparison results according to age groups were determined. There was no statistically significant difference between right or left styloid process lengths according to age groups. The mean length of the styloid process of the cadavers and dry bones was 22.54 + or - 4.24, and there was no significant difference between the right and left sides of the cadavers and dry bones. The incidence of the elongated styloid process was determined as 3.3%, and the elongations revealed a female dominance. The average length of the elongated styloid process was 36.06 + or - 6.12 mm, while the mean length of the styloid processes of the subjects reporting Eagle's syndrome was 40 + or - 4.72 mm. The results of this morphological study will assist clinicians in the diagnosis of Eagle's syndrome.

Abstract
OBJECTIVES Disc degeneration probably begins in childhood although low back pain and radicular leg pain is not as common a complaint as in adults. However as yet no explanation exists for the appearance of advanced degenerative changes seen occasionally in patients in their twenties. PATIENTS AND METHODS We report 12 adolescents between the ages of 15 and 20 among a total of 1068 cases with radiologically demonstrated lumbar disc herniations treated between March 1991 and March 1996. RESULTS Most of their findings were in good agreement with earlier and more recent reports. The only different findings worth commenting upon were the common presence of multiple level disc herniations, and the occasional presence of a so called "fractured epiphysial plate". CONCLUSION Depending on magnetic resonance imaging findings coupled with computed tomographic images; we suppose that the so called "fractured bone fragments of the vertebral epiphysial rim impinging on the spinal canal at multiple levels" and "wedges of bone attached to the disc end plate and associated bony defects in the margins of the posterior vertebral bodies" reported to be demonstrated on computed tomographic (CT) images may in fact be false images. Inappropriately angled CT scan slices may cut partly through the epiphysial ring which has totally been distracted backwards together with the firmly attached avulsed disc annuli, designated as an "epiphysial avulsion"; giving rise to the mistaken interpretation as a "fractured epiphysial ring" appearance. Such a mechanism may also involve the posterior longitudinal ligament, which is firmly attached to the neighboring annuli, accounting for the common multilevel involvement.

Abstract
PURPOSE The high cure rate in testicular cancer has provoked investigations relating to the quality of life in long-term survivors. We determine the psychosocial consequences of the disease especially in regard to sexual and professional performance. MATERIALS AND METHODS Among the testicular cancer patients treated with various treatment modalities 140 rendered free of disease for at least a year were included in this study. General Health Questionnaire 28 and a general survey were used to determine quality of life issues. RESULTS Regarding the sexual life of these patients, problems related to libido, erection and ejaculation increased significantly during treatment and subsequently recovered but did not return to baseline after treatment. During treatment the frequency of sexual intercourse and/or masturbation decreased significantly in all patients. Of the single patients 35% thought that medical history would be a concern for the potential spouse. Regarding professional lives, 22.4% thought that they had better performance after treatment compared to before therapy, whereas only 6.1% reported it to be worse. When professional performance was analyzed according to the treatment modalities those who had received radiotherapy did worse. General Health Questionnaire scores indicated that patients with this disease had a positive view of life compared to that of the normal population. CONCLUSIONS Although we observed a substantial recovery in sexual life after treatment, it was evident that therapy did have a negative effect on sexual functions. There was no effect on occupational performance and perspective of life, which may be related to the fact of having overcome a life threatening disease.

Abstract
This report presents the results of a test-retest reliability study of the alcohol and drug dependence, as well as harmful use/abuse were investigated in Ankara, Turkey and Farmington, Connecticut (US). Reliabilities for the past year, prior to past year, and lifetime diagnosis of alcohol and drug use disorders were evaluated using ICD-IO, DSM-III-R and DSM-IV criteria. The results indicate that SCAN alcohol and drug diagnosis have good to excellent levels of reliability for dependence across different substances, different diagnostic systems, and different cultural groups. Diagnostic classification of alcohol and drug abuse/harmful use was considerably less reliable. Implications of the findings are discussed.

Abstract
The General Health Questionnaire is a widely used screening instrument. It detects a wide range of psychological disorders, mainly the anxiety/depression spectrum, and has been shown to be a valid and reliable instrument across cultures. This study reports the psychometric properties of the 12- and 28-item versions of the questionnaire among Turkish primary care attenders, focusing mainly on the factor structures. Both questionnaires were found to be reliable and they had factor structures consistent with the original studies.
