BACKGROUND/OBJECTIVES: Sarcopenia and sarcopenic obesity (SO) are geriatric syndromes leading to physical disability, poor quality of life and death. The aim of this study was to investigate the prevalence of sarcopenia and SO in nursing homes in Turkey and to define local disparities for diagnosing sarcopenia and SO. SUBJECTS/METHODS: This cross-sectional multicenter study was performed in 711 patients in 14 nursing homes. Comprehensive geriatric assessment tests, handgrip strength and calf circumference (CC) measurements were carried out. Sarcopenia was both defined by handgrip strength and CC criteria. RESULTS: According to handgrip strength measurement, 483 (68%) of patients were sarcopenic (male: 72%, female: 63.8%), 228 were non-sarcopenic. The prevalence of SO was 22% (13.7% in men, 30.2% in women). Patients (82.5%) who were diagnosed as sarcopenic by the handgrip strength test were not sarcopenic according to CC sarcopenia criteria. Therefore, we tried to determine the optimal CC value for diagnosing sarcopenia in our population. CONCLUSIONS: Both sarcopenia and SO were prevalent among Turkish nursing home elderly residents. Most of the patients with sarcopenia were obese or overweight. We showed that diagnosing sarcopenia with CC measurement underestimated the sarcopenia prevalence assessed by handgrip strength. So we concluded that, although different assessment methods are recommended for the diagnosis of sarcopenia local disparities should be considered.

BACKGROUND AND AIMS: Obesity is one of the most common diseases in the world. Particularly in elderly subjects, the effects of weight loss on cardiac functions have not been previously investigated by means of pulsed wave tissue doppler imaging (PWTDI). Using PWTDI, we examined the effects of weight loss on cardiac functions and left ventricular (LV) mass in obese geriatric women. METHODS: Thirteen obese women aged 66-83 years (mean age 71.2+/-4.9 yrs) with a body mass index 35.6-49 kg/m2 (mean body mass index 39.9+/-4.3 kg/m2) were evaluated by echocardiography and PWTDI. Only subjects with uncomplicated obesity were included. All measurements, including anthropometric variables, systolic and diastolic indices, and LV mass, were made before and after a 6-month Orlistat plus hypocaloric diet. Myocardial systolic wave (Sm) velocity, isovolumic acceleration (IVA), myocardial precontraction time (PCTm) and the PCTm to contraction time (CTm) ratio were calculated as systolic indices. Early diastolic wave (Em), late diastolic wave (Am), Em to Am ratio, myocardial relaxation time (RTm), deceleration time (DT) and isovolumic relaxation time (IVRT) were determined as diastolic measurements. RESULTS: Subjects lost an average of 8.4+/-1.2 kg. LV mass decreased significantly after weight loss (p<0.001). In addition, IVRT decreased significantly (p=0.038). Only RTm decreased significantly (p=0.016), whereas other PWTDI parameters of LV remained the same. In the right ventricle, Sm velocity, IVA, Em, and Am velocities were similar. However, the PCTm to Am ratio decreased significantly (p=0.006), and the Em to Am ratio increased (p=0.04) and RTm decreased significantly (p=0.016) after weight loss. CONCLUSIONS: In obese geriatric women, weight loss improves ventricular diastolic functions and decreases LV mass. It also contributes to partial improvement in right ventricular systolic function.

Purpose: Parkinson's Disease (PD), a neurodegenerative disorder, is associated with substantial morbidity. α-Klotho, an anti-aging protein known for its neuroprotective properties, has gained attention. This study aims to assess serum levels of α-Klotho in PD patients., Methods: This study is a cross-sectional case-control study. PD was diagnosed according to UK Parkinson Disease Society Brain Bank criteria. Serum α-Klotho level was measured using a commercially available enzyme-linked immunosorbent assay., Results: Of the 314 participants in the study, 157 were patients with PD and 157 were controls. Lower levels of α-Klotho were observed in PD (0.85 nmol/L) in comparison to the controls (1.47 nmol/L, p < 0.001). α-Klotho levels were also significantly lower among PD patients with dementia compared to PD patients without dementia. In logistic regression analysis, α-Klotho (OR: 0.04, p < 0.001) demonstrated a significant relationship between PD. A significant correlation was identified between α-Klotho levels and Mini-Mental State Examination scores in PD patients. The sensitivity and the specifity of α-Klotho were 90% and 65% for predicting PD., Conclusions: Our findings suggest that α-klotho could potentially serve as a biomarker. However additional studies are needed to confirm our findings., (© 2024. Fondazione Società Italiana di Neurologia.)

Background: Several screening tools have been developed to identify sarcopenia. However, data on the use of these screening tools in hospital settings are limited. This study assessed the diagnostic accuracy of three screening methods-strength, assistance walking, rising from a chair, climbing stairs, and falls (SARC-F); SARC-F combined with calf circumference (SARC-CalF); and the Ishii tests-for detecting sarcopenia in older individuals who are hospitalized., Methods: This study included 204 older people who were hospitalized. Sarcopenia was assessed relative to the diagnostic criteria established by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2). Muscle mass, muscle strength, and physical performance were evaluated using bioimpedance analysis, handgrip strength, and usual gait speed, respectively. Sensitivity and specificity analyses were conducted for the SARC-F, SARC-CalF, and Ishii tests to determine their effectiveness. Receiver operating characteristics curves were generated, and the area under curve was calculated to compare the overall diagnostic accuracy of the SARC-F, SARC-CalF, and Ishii tests., Results: The SARC-F, SARC-CalF, and Ishii tests demonstrated sensitivities of 72%, 88.6%, and 93.5%, respectively, and specificities of 41%, 78.5%, and 30.3%, respectively., Conclusions: SARC-CalF demonstrates the highest performance in terms of sensitivity and specificity compared with the other two tests, making it a valuable tool for detecting sarcopenia in hospital settings. In contrast, the Ishii test exhibits high sensitivity but low specificity within this population. Based on our results, we found that SARC-CalF can be used as a simple, effective test for identifying sarcopenia in older patients in the hospital setting., (© 2024 American Society for Parenteral and Enteral Nutrition.)

Objectives: To assess the impact of sarcopenia and vitamin D levels on the severity of lower urinary tract symptoms (LUTS)., Methods: A total of 193 male patients, aged 60 years and above, who visited the geriatric outpatient clinic at Ibn-i Sina Hospital in Ankara, Turkey, between December 2019 and March 2021, were enrolled. Sarcopenia was diagnosed according to the criteria set by the European Working Group on Sarcopenia in Older People. The presence and severity of lower urinary tract symptoms were assessed using the International Prostate Symptom Score questionnaire, categorizing symptom severity as mild or moderate-to-severe., Results: The median patient age was 71 years (range: 66-77). Sarcopenia affected 24.9% of the population studied. Mild LUTS was observed in 43.5% and moderate-to-severe LUTS was observed in 56.5% of patients. Sarcopenia prevalence was significantly higher in the individuals with moderate-to-severe LUTS compared to those with mild-LUTS ( p =0.021). After adjusting for Charlson comorbidity index and age, only vitamin D levels were significantly associated with increased odds of moderate-to-severe LUTS (odds ratio [OR]=0.95, 95% confidence interval [CI]: [0.92-0.98], p =0.002). Sarcopenia was not significantly associated with the severity of LUTS (OR=2.04, 95% CI: [0.94-4.45], p =0.070). An inverse linear trend was observed between quartiles of 25 (OH) vitamin D and LUTS severity. As 25 (OH)vitamin D levels increased, the proportion of patients with moderate-to-severe LUTS decreased ( p =0.023)., Conclusion: Sarcopenia did not significantly impact LUTS severity, but low vitamin D levels were associated with moderate-to-severe LUTS., (Copyright: © Saudi Medical Journal.)

Background: Frailty indicates older people who are vulnerable to stressors. The relation between ultrasonographic parameters of muscle and frailty among older people has yet to be investigated., Aims: The aim of the study is to investigate the relationship between frailty and the ultrasonographic measurements of the rectus femoris muscle (RFM)., Methods: This cross-sectional study included 301 participants who were ≥65 years. The FRAIL questionnaire assessed frailty. The thickness, cross-sectional area (CSA), fascicle length, pennation angle (PA), stiffness, and echogenicity of RFM were assessed by ultrasound. The accuracy of parameters in predicting the frailty was evaluated by ROC analysis., Results: Of all 301 participants, 24.6% were frail. Pre-frail and frail participants had significantly lower thickness (p = 0.002), CSA (p = 0.009), and fascicle length (p = 0.043) of RFM compared to robust. PA was significantly lowest in frails (p < 0.001). The multivariate logistic regression analysis showed that PA values lower than 10.65 degrees were an independent predictor of frailty (OR = 0.83, 95% Cl: 0.70-0.97, p = 0.019). Results of ROC analysis demonstrated a satisfactory result between the PA and frailty (AUC = 0.692, p < 0.001)., Discussion: Thickness, CSA, and PA of RFM were found to be lower in frail subjects, which may indicate the changes in muscle structure in frailty. Among all parameters, lower PA values were independent predictors of frailty. These findings may indicate a novel ultrasound-based method in frailty, that is more objective and unrelated to the cross-sectional evaluation., Conclusions: Ultrasonographic measurements of RFM, especially the lower PA may predict frailty in older people. As an objective and quantitative method, PA may be used to define frailty with acceptable sensitivity., (© 2024. The Author(s).)

Purpose: Skeletal muscle ultrasonography stands out as a promising method for detecting sarcopenia. We aimed to evaluate the relationship between sarcopenia, sarcopenia related quality of life and US findings of the Rectus Femoris muscle., Methods: A total of 300 older individuals were included in this cross-sectional study. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People 2 criteria. Rectus F muscle thickness, cross-sectional area, fascicle length, pennation angle, stiffness and echogenicity were measured by an experienced radiologist using a B-mode US device. Quality of life was determined with the Sarcopenia- Quality of life questionnaire. Correlation analysis, receiver operating analysis, sensitivity and specificity analysis were performed., Results: The median age of participants was 72. 191 (63.9%) and 109 (36.1%) of the participants were male and female, respectively. The prevalence of sarcopenia was 15.6%. Fascicle length, cross-sectional area and thickness showed the highest sensitivity (81%) and specificity (87%) for men. Fascicle length and pennation angle showed the highest sensitivity (87%) and specificity (66%) for women. Rectus Femoris ultrasound parameters differed across SarQoL quartiles, and higher Sarcopenia- Quality of life scores were associated with better ultrasound parameters. All ultrasound parameters had positive correlations with Sarcopenia- Quality of life., Conclusion: Different Rectus Femoris ultrasound parameters are useful for detecting sarcopenia according to gender. A combination of these parameters can increase diagnosis accuracy. Ultrasound parameters are associated with sarcopenia related quality of life., (© 2023.

Purpose: Falls are an important cause of morbidity and mortality in geriatric patients. Sarcopenia and central blood pressure may be associated with falls. This study aimed to investigate the association between sarcopenia and blood pressure parameters in older patients with falls., Methods: A comprehensive geriatric evaluation of 72 elderly patients was performed using established assessment tests. Peripheral and central hemodynamic measurements, including office DBP and SBP, daytime-night peripheral and central DBP and SBP, cardiac output, augmentation index, pulse wave velocity (PWV), pulse rate, and peripheral resistance and reflection, were measured with a 24-hour ambulatory blood pressure measuring device., Results: Of 72 patients with a mean age of 77.51 ± 6.5 years, 12 (16.7%) were non-sarcopenic, 32 (44.4%) were probable, nine (12.5%) were confirmed, and 19 (26.4%) were severe sarcopenic. PWV, which is an indicator of arterial stiffness, was found to be significantly higher in the sarcopenic group. The other cardiac risk markers [daytime peripheral SBP, mean arterial pressure (night), pulse pressure (daytime), and peripheral resistance (daytime and night)] were significantly lower in the sarcopenic patients. PWV correlated with gait speed, Katz score, and hand grip strength (Spearman's rho: -0.337, -0.310, and -0.334; P < 0.001, 0.008, and 0.001, respectively). Age and hypertension were the most important factors increasing the risk of falls., Conclusion: Sarcopenia is associated with central and peripheral blood pressure changes in patients with falls. When sarcopenia is diagnosed in older people with falls, 24-hour ambulatory peripheral and central pressures should be evaluated for cardiac risk screening., (Copyright © 2021 Wolters Kluwer Health, Inc.

Introduction: In advanced age, both sarcopenia and erectile dysfunction (ED) occur with similar underlying causes through different mechanisms. In our study we investigated the association between sarcopenia and ED in older men., Methods: A total of 193 male patients aged 60 years and older were included in the study. The presence of sarcopenia was investigated in accordance with EWGSOP2 diagnostic criteria. For evaluation of ED, we used the 5-question International Index of Erectile Dysfunction questionnaire with categories of no ED, mild-moderate ED, and moderate-severe ED. Total testosterone levels were measured., Results: The median age of the patients was 71.9 (range 60-93 years). The prevalence of sarcopenia was 24.9%, and moderate-severe ED was 49.2%. Moderate-severe ED was more common in patients with sarcopenia than those without (70.8% vs 42.1%, p < 0.001). After adjustment for age and Charlson Comorbidity Index, the presence of sarcopenia was significantly associated with moderate-severe ED with odds ratio (OR) of 2.71 (95% Confidence Interval [CI] 1.29-5.73, p = 0.009). The components of sarcopenia were assessed separately in multivariate analysis. Muscle strength and muscle mass were significantly associated with moderate-severe ED with OR of 0.93 (95%CI 0.89-0.98) and 0.68 (95%CI 0.54-0.86), respectively, whereas gait speed was not associated with moderate-severe ED., Conclusion: The presence of sarcopenia in older men is associated with an increased risk of moderate-severe ED. In addition, decreased muscle strength and decreased muscle mass are associated with an increased risk of moderate-severe ED. Prospective studies are needed to reveal the causality between sarcopenia and ED., (Copyright © 2021. Published by Elsevier B.V.)

Background: The methods used in the diagnosis and screening of sarcopenia are not available everywhere. There is a need for more practical tests that can be used especially in the first step., Aims: We aimed to investigate the usability of blink rate as an alternative test for dynapenia screening., Methods: A total of 355 patients ≥ 65 years of age (254 (71.50%) female and 101 (28.50%) male) who were admitted to geriatric outpatient clinic were included in this prospective cross-sectional study., Results: Blink rate was positively correlated with grip strength and negatively correlated with SARC-F. Also, it was found that the blink rate was associated with dynapenia independent of other factors. The optimal cut-off value of 15 s blink rate to predict dynapenia was measured as ≤ 40.5, with 70.3% sensitivity and 43.3% specificity., Conclusion: Our study indicated the relationship between blink rate with dynapenia and grip strength. Especially in patients with limited mobilization and where it is not possible to reach the hand dynamometer to measure grip strength, the blink rate can be used as an alternative test to detect dynapenia., (© 2021.

Background: A curfew for elderly people was announced in Turkey to protect the geriatric population during the COVID-19 pandemic. Although this may have the beneficial effect of preventing infection, psychological distress may also increase with prolongation of the pandemic., Methods: Geriatric patients were interviewed by telephone due to the ongoing curfew. Demographical characteristics, comorbidities, personal risk perception of COVID-19, common concerns related to COVID-19, and experiences of delayed hospital admission due to the pandemic were recorded. The Hospital Anxiety and Depression Scale (HADS) was used to assess psychological distress, anxiety, and depression., Results: Participants (n = 136; 82 females, 60.3%) had a mean age of 73.4 ± 5.9 years. The most common comorbidity was hypertension (75%). Approximately 80% of the participants reported a decrease in physical activity during the curfew period. The HADS scores indicated rates of anxiety as 25.7% and depression as 16.9%. Anxiety was significantly more common in females than males (P = 0.002). Sleep problems (P = 0.000), fatigue (P = 0.000), and hopelessness (P = 0.000) were more common in participants with depression and anxiety. Logistic regression analyses showed an association between a delay in hospital admission and the presence of depression (P = 0.0029, R 2  = 0.146). Personal risk perception of COVID-19 was statistically significantly higher among patients with anxiety (P = 0.0027, R 2  = 0.157)., Conclusion: Decreased adaptation to external and internal factors among older individuals may facilitate unfavourable outcomes of the pandemic. These results indicate that the geriatric population was mentally and physically affected by the restrictions and isolation., (© 2021 Japanese Psychogeriatric Society.)

Purpose: To investigate the risk of sarcopenia in hospitalized older patients and to assess the associations between sarcopenia risk and health care outcomes including dependency, malnutrition, and dysphagia., Methods: This multicenter cross-sectional study was a part of the annual National Prevalence Measurement of Quality of Care (LPZ) in Turkey. Hospitalized patients age 65 and older were included in the study. The SARC-F was used to assess risk of sarcopenia. Dependency was appraised according to the Care Dependency Scale (CDS). Nutritional status was established with respect to the Malnutrition Universal Screening Tool (MUST). Dysphagia was screened by two structured questions., Results: A total of 492 patients were included in the analysis. Two hundred and forty patients (48.8%) were at risk of sarcopenia. Sarcopenia risk was more prevalent among women (p = 0.007) and patients with risk of sarcopenia were older (p < 0.001). Hospital stay was longer and malnutrition and dysphagia were more prevalent in patients with sarcopenia risk than without (all p < 0.001). All nutritional interventions were applied mostly to patients with sarcopenia risk than without. In multivariate analysis, advanced age (OR: 1.068, CI 1.032-1.104, p < 0.001), female gender (OR: 2.414, CI 1.510-3.857, p < 0.001), and dependency (OR: 5.022, CI 2.922-8.632, p < 0.001) were independently associated with sarcopenia risk., Conclusions: Sarcopenia risk is related with unfavorable outcomes in hospitalized patients. Primarily older female patients are at risk for sarcopenia. It is important to recognize sarcopenia at an early stage and to prevent its progression, before dependency develops. The SARC-F may be a useful tool for screening sarcopenia risk in hospitalized patients., (© 2021. European Geriatric Medicine Society.)

Background: Frailty is a medical syndrome resulting in loss of endurance, strength and physiological function. There is insufficient data to understand the process of frailty formation at the gene level, however one of the product of Klotho gene known as an anti-aging gene with many functions that prolong lifespan is alpha klotho protein. We aimed to investigate the relationship between frailty and the serum alpha klotho protein levels., Methods: In this cross-sectional analysis, there were 89 patients aged 65 years old and older, 45 of whom were frail and 44 of whom were not frail, were included in the study. Within the scope of the study, a sociodemographic and clinical information form, the Turkish version of the FRAIL scale and a comprehensive geriatric assessment were evaluated. In addition to routine laboratory tests, plasma alpha klotho protein levels were measured., Results: The mean alpha klotho protein levels of the patients were 0.76 ± 1.01 ng/ml in the control group and 0.54 ± 0.61 ng/ml in the frail group, however, there was no statistically significant difference between the two groups (p = 0.286). C-reactive protein (CRP) levels were significantly higher and hemoglobin (Hb) levels were significantly lower in the frail patients compared to the control group (p < 0.05). It was observed that alpha klotho protein level was inversly correlated with increased CRP levels but association was weak (p = 0.022, R: -0.245). Hb levels (p = 0.018, R: 0.250) was weakly correlated with alpha klotho protein level., Conclusion: No significant relationship was found between frailty and alpha klotho protein levels in the geriatric patients. Further comprehensive studies are needed to explore this subject., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Background: We aimed to investigate the effects of zoledronic acid treatment on daily living activities, cognitive functions, depression, muscle strength, and performance., Methods: The study was conducted retrospectively. Bone mineral densitometry (BMD) values, Katz activities of daily living (ADL), Lawton-Brody instrumental activities of daily living (IADL), mini mental state examination (MMSE), geriatric depression scale (GDS), mini nutritional assessment (MNA), grip strength, and gait speed scores before and 6 months after zoledronic acid administration were compared., Results: A total of 115 patients were included in the study. There was a significant increase in lumbar total (p < .001), femoral neck (p = .002), and femur total (p = .001) BMD values after zoledronic acid treatment. Significant decrease was found in MMSE (p = .016) and gait speed scores (p = .008) after zoledronic acid treatment, but no significant difference was found in terms of Katz ADL, Lawton-Brody IADL, MNA, GDS, and grip strength (p > .05)., Conclusion: Our study indicated that zoledronic acid did not affect daily living activities, depression, and muscle strength. Although we have concluded that cognitive and muscle performance may be adversely affected by zoledronic acid treatment.

Background and Aim: Sarcopenia and sarcopenic obesity (SO) are associated with adverse health outcomes in older people. Data on sarcopenia- and SO-related mortality are insufficient for hospitalized older people. The aim of this study was to evaluate the relationship between sarcopenia, SO and mortality among hospitalized older people., Methods: Two-centered prospective observational study was conducted among 350 hospitalized older people in geriatric units of two university hospitals. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People. Obesity was defined according to fat mass percentage. Medical history, cognitive status, nutritional status and functionality and laboratory tests were assessed. All-cause mortality rate was recorded at 2 years., Results: The prevalence of SO was 21.1%. The prevalence of sarcopenia was 11.4%. Both sarcopenia (log rank p < 0.001) and SO (log rank p < 0.001) were associated with all-cause mortality at 2 years. There was no difference between sarcopenia and SO for mortality. SO (HR 5.23, p < 0.001), sarcopenia (HR 9.26, p < 0.001), male gender (HR 2.25, p = 0.035), Lawton IADL (HR 0.77, p = 0.02), heart failure (HR 3.25, p = 0.02) and chronic obstructive lung disease (HR 5.16, p = 0.01) were independently related to all-cause mortality., Discussion and Conclusions: Both sarcopenia and SO showed an independent relationship for 2-year all-cause mortality after hospital discharge. These results suggest that preventive and treatment options should be taken to decrease mortality associated with these conditions among hospitalized older people.

Background: Vitamin D deficiency is known to cause increased predisposition to various infectious diseases and the addition of vitamin D to antimicrobial treatment may improve treatment responses. However, the relationship between vitamin D and Helicobacter pylori (H. pylori) remains to be determined., Aims: To assess the association between vitamin D deficiency and H. pylori infection., Methods: This cross-sectional study included patients aged 65 and over, who underwent gastroscopy and had gastric biopsy performed between 2010 and 2017. Of the 441 patients, 254 had available 25-hydroxyvitamin D level results and were included in the analyses. Patients were categorized into H. pylori (+) and H. pylori (-) groups, according to histopathological examination results of gastric biopsies. Serum 25(OH) vitamin D levels less than 20 ng/mL were defined as vitamin D deficiency., Results: Of all patients, 43 were H. pylori (+) and 211 were H. pylori (-). More patients had vitamin D deficiency (< 20 ng/mL) in the H. pylori (+) group than the H. pylori (-) group (86% vs 67.3%, p = 0.014). The proportion of H. pylori (+) patients decreased across increasing quartiles of 25(OH) vitamin D levels (p for trend = 0.010). In multivariable logistic regression analysis, vitamin D deficiency was associated with increased odds of H. pylori infection after adjustment for age, gender, and Charlson Comorbidity Index (OR = 3.02, 95% CI 1.19-7.69, p = 0.020)., Conclusion: Vitamin D deficiency can be associated with increased risk of H. pylori infection. The potential protective effect of vitamin D against H. pylori infection and its possible role in the treatment of H. pylori should be evaluated in prospective trials.

Aim: The aim of the present study was to evaluate the relationship between mortality and sarcopenia defined by the criteria of the European Working Group on Sarcopenia in Older People in older nursing home residents in Turkey., Methods: This was an observational prospective study. Nursing home residents who were aged older than 65 years and living in the Seyranbagları Nursing Home and Rehabilitation Center (Ankara, Turkey) were recruited for the study. The main outcome measure was the relationship between sarcopenia and mortality. Diagnosis of sarcopenia was carried out according to the European Working Group on Sarcopenia in Older People criteria. Bioelectrical impedance analysis was used for skeletal muscle mass measurement. Muscle strength and muscle performance were evaluated by handgrip testing and gait speed, respectively. Mortality was assessed at the end of 2 years. The Kaplan-Meier method and Cox regression analysis were used to evaluate the relationship between sarcopenia and all-cause mortality., Results: The prevalence of sarcopenia and severe sarcopenia were 29% and 25.4%, respectively. A total of 44% (18) of sarcopenic participants died, whereas 15% (15) of participants without sarcopenia died after 2 years of follow up (P < 0.001). After adjusting for confounding factors, sarcopenia was associated with all-cause mortality among older nursing home residents in Turkey (HR 2.38, 95% CI 1.04-5.46; P = 0.039). However, sarcopenia was not significantly related with mortality after adjustment of MNA score (HR 2.04, 95% CI 0.85-4.9; P = 0.1)., Conclusions: Sarcopenia independently increases all-cause mortality in older nursing home residents in Turkey. Nutritional status plays a role in sarcopenia-related mortality. Geriatr Gerontol Int 2017; 17: 1118-1124., (© 2016 Japan Geriatrics Society.)

Aim: Sarcopenia is prevalent in older people, and is related to survival and disability. There are no data on sarcopenia evaluated according to European Working Group on Sarcopenia in Older People criteria for nursing home residents in Turkey. We aimed to evaluate the prevalence of sarcopenia according to European Working Group on Sarcopenia in Older People criteria and associated factors with sarcopenia among nursing home residents in Turkey., Methods: The study cohort consisted of individuals aged over 65 years and living in the Seyranbağları Nursing Home and Rehabilitation Center in Ankara, Turkey. Besides demographic and medical data, Mini-Mental State Examination, activities of daily living, Mini-Nutritional Assessment, body mass index, calf circumference, gait speed and handgrip strength were also investigated. Muscle mass was evaluated by bioelectrical impedance analysis. Sarcopenia was diagnosed according to European Working Group on Sarcopenia in Older People criteria., Results: A total of 141 older individuals were evaluated. Sarcopenia was found in 29% (n = 41) of the participants. Participants with sarcopenia were older and had low scores for activities of daily living, low body mass index, greater cognitive dysfunction, high malnutrition risk and low calf circumference. Body mass index and calf circumference were found to be associated with sarcopenia in multivariate logistic regression analysis., Conclusions: Almost one-third of older nursing home residents were diagnosed with sarcopenia according to European Working Group on Sarcopenia in Older People criteria in this study in Turkey. Calf circumference and body mass index were associated with increased risk of sarcopenia among nursing home residents. This is the first study evaluating sarcopenia using European Working Group on Sarcopenia in Older People criteria in Turkey.

In Parkinson's disease (PD), non-motor symptoms may occur such as autonomic dysfunction. We aimed to evaluate both parasympathetic and sympathetic cardiovascular autonomic dysfunction in older PD cases. 84 PD cases and 58 controls, for a total of 142, participated in the study. Parasympathetic tests were performed using electrocardiography. Sympathetic tests were assessed by blood pressure measurement and 24-hour ambulatory blood pressure measurement. The prevalence of orthostatic hypotension in PD patients was 40.5% in PD patients and 24.1% in the control group (p> 0.05). The prevalence of postprandial hypotension was 47.9% in the PD group and 27.5% in the controls (p <0.05). The prevalence of impairment in heart rate response to deep breathing was 26.2% in the PD group and 6.9% in the control group (p <0.05). The prevalence of postprandial hypotension in PD with orthostatic hypotension was 94% and 16% in PD patients without orthostatic hypotension (p <0.05). The prevalence of impairment in heart rate response to deep breathing was 52.9% in PD patients with orthostatic hypotension and 8% in PD cases without orthostatic hypotension (p<0.05). The prevalence of impairment in heart rate response to postural change was 41% in PD cases with orthostatic hypotension and 12% in PD cases without orthostatic hypotension (p <0.05).Although there are tests for assessing cardiovascular autonomic function that are more reliable, they are more complicated, and evaluation of orthostatic hypotension by blood pressure measurement and cardiac autonomic tests by electrocardiography are recommended since these tests are cheap and easy.

In this study, the importance of plasma viscosity (PV) as a biomarker in differential diagnosis of dementia subtypes especially Alzheimer's disease (AD) and vascular dementia (VaD) was investigated. Our study recruited 45 patients with AD, 35 patients with VaD, and control participants. Individuals with inflammatory disease, infection, heart, liver, renal failure, and with high erythrocyte sedimentation rate and C-reactive protein levels were excluded from the study. The cases underwent comprehensive geriatric assessment. The PV measurements were performed with Brookfield DV-II viscometer. The PV measurements of AD, VaD, and control groups were 1.61 ± 0.08, 1.70 ± 0.06, and 1.48 ± 0.06 mPa S, respectively. The PV levels of the dementia group were significantly higher than the control group (P < .001). When the dementia group was analyzed by itself, patients with VaD had higher PV levels than the patients with AD (P < .001). The PV is a biomarker to be used in diagnosis as well as in differentiating between the 2 most common forms of dementia which are AD and VaD.

Objectives: To compare the sensitivity and specificity of C[14] urea breath test with histopathological findings in biopsies obtained through endoscopy., Methods: In this cross-sectional study, conducted at the Medical Faculty Ankara University, Ankara, Turkey between January and October 2009, 100 patients aged 65 and above who fulfilled the criteria for inclusion were enrolled. Oesophago-gastroduodenoscopy was carried out on the patients after eight hours of fasting, using a Fujinon endoscope, by the same expert. C14 urea breath tests were carried out on all patients with a capsule containing 37 kBq(1micro Ci) C14 urea/citric acid. Evaluation of all data was carried out using SPSS 11.5. Categorical variables were compared through Pearson Chi squared or Fisher's exact test. P < 0.005 was taken as statistically significant., Results: The average age of the patients was 71 +/- 5 years; 43 (43%) were male; and 57 (57%) were female. Helicobacter pylori positivity was found to be 35 (35%) in histopathological evaluation, and 36 (36%) in the C14 urea breath test. Of the 35 patients, 32 (91.4%) were found to be positive by the C14 urea breath test also. Of the 65 patients who were found to be negative on histopathology, 61 (93.8%) were also found to be Hp negative by the C14 urea breath test, and 4 (6.2%) were evaluated as false positive. A statistically significant correlation (p < 0.001) was found between histopathological and C14 urea breath test results. Compared with histopathology, the sensitivity of the urea breath test was 91.4%, and its specificity was 93.8%. A statistically significant (p < 0.001) relationship was found between histopathological results and the results of the C14 urea breath test., Conclusion: The sensitivity and specificity of the C[14] urea breath test in the group of elderly patients selected was high. The C14 urea breath test can be considered in the elderly group for diagnosis of Helicobacter pylori infection.
