RESUMEN
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.

BACKGROUND: Depression is the most common psychiatric problem in older individuals. In some countries, the common approach is to ignore psychiatric disorders. This study aimed to reveal the importance of newly diagnosed high depression scores in the geriatric population admitted to outpatient clinics with somatic complaints. METHODS: Patients who did not have a previous diagnosis of a psychiatric disorder and were not receiving treatment were included in the study. A comprehensive geriatric evaluation of 235 elderly patients was performed using established assessment tests. The time and quality of sleep and the Clinical Frailty Scores (CFSs) were documented. RESULTS: The mean age of the 235 patients was 73.6 ± 6.39 years, 65.5% (n = 154) were women, and 34.9% (n = 81) had a geriatric depression score ≥ 5. In the higher depression rating scores group, the Lawton-Brody, Mini-Mental State Examination (MMSE), and Mini Nutritional Assessment (MNA-SF) scores were low (p = 0.010, p < 0.001, p = 0.003). Sleep duration was short, and sleep quality was poor (p = 0.042, p = 0.006). The CFSs were high. (p = 0.035) According to the regression analysis results, the MMSE, MNA-SF and CFS predicted higher depression scores significantly (p = 0.048, ß = .892; p = 0.045, ß = .661; p = 0.045, ß = 1.245). DISCUSSION: Depression scores in older people may be associated with not only mood but also the functionality. As with other geriatric syndromes, symptoms in depression may be atypical rather than typical.

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, R2 = 0.146). Personal risk perception of COVID-19 was statistically significantly higher among patients with anxiety (P = 0.0027, R2 = 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.

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.

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.

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.

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.

OBJECTIVES: Technetium-99m diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) is an ideal radioisotopic method having a high correlation with inulin clearance for the determination of glomerular filtration rate (GFR). Different formulas like creatinine clearance (CrCl) in 24 h urine samples, Cockroft-Gault formula (CGF), and modification of diet in renal disease (MDRD) are being used to come up with an estimate. In this study, we compared (99m)Tc-DTPA with the formulas mentioned above in an attempt to best identify the method that would yield the nearly ideal GFR estimates in the elderly. MATERIALS AND METHODS: In 76 patients who were admitted to our clinic, we measured 24 h urine volume (V), urine creatinine (Ucr), and serum creatinine (Scr) levels together with CrCl, Scr, serum urea (Su), and albumin (Alb) levels. By using coefficients identified for age, gender, and race, we calculated modification of diet in renal disease 1 (MDRD1). Different from MDRD1, we calculated modification of diet in renal disease 2 (MDRD2) that does not include Su and Alb parameters and formulas like CGF that include Scr, age, gender, and weight parameters to come up with GFR levels. All patients underwent (99m)Tc-DTPA procedure. RESULTS: The mean of the GFR values measured by (99m)Tc-DTPA was 54.3 ± 19.9. The means of GFR values calculated by CrCl, MDRD1, MDRD2, and CGF were 58.0 ± 30.5, 60.9 ± 22.1, 54.4 ± 20.1, and 57.9 ± 22.4, respectively. GFR as measured by (99m)Tc-DTPA showed statistically significant correlations with the results of other methods (p < 0.001 for all methods). The most significant correlation was with MDRD1. CONCLUSION: MDRD1 can be used for next to ideal and accurate predictions of GFR in the elderly in the daily practice.

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.

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.

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.

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.

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: 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.
RESUMEN
BACKGROUND: Diagnosis and screening of frailty, a condition characterized by an increased vulnerability to adverse outcomes of COVID-19, has emerged as an essential clinical tool which is strongly recommended by healthcare providers concerned with hospitalized elderly population. The data showing the role of frailty in patients infected with COVID-19 is needed. METHODS: This was a nationwide cohort study conducted at all hospitals in Turkey. All COVID-19 hospitalized patients (≥ 65 years) were included. Patients who were alive and not discharged up to July 20, 2020, were excluded. The frailty was assessed by using the "Hospital Frailty Risk Score" (HFRS). Patients were classified into three risk groups of frailty based on previously validated cut points as low (<5 points), intermediate (5-15 points), and high (>15 points). Additionally, patients who had the HFRS of ≥5 were defined as frail. The primary outcome was in-hospital mortality rates by frailty group. RESULTS: Between March 11, 2020, and June 22, 2020, a total of 18,234 COVID-19 patients from all of 81 provinces of Turkey were included. Totally, 12,295 (67.4%) patients were defined as frail (HFRS of >5) of which 2,801 (15.4%) patients were categorized in the highest level of frailty (HFRS of >15). Observed in-hospital mortality rates were 697 (12.0%), 1,751 (18.2%) and 867 (31.0%) in low, intermediate and high hospital frailty risk, respectively (p<0.001). Compared with low HFRS (<5), the adjusted odds ratios for in-hospital mortality were 1.482 (1.334-1.646) for intermediate HFRS (5-15) and 2.084; 95% CI, 1.799-2.413 for high HFRS (>15). CONCLUSIONS: As a claims-based frailty model, the HFRS provides clinicians and health systems, a standardized tool for an effective detection and grading of frailty in patients in COVID-19. A frailty-based tailored management of the older population may provide a more accurate risk categorization for both therapeutic and preventive strategies.

BACKGROUND: The oxidative stress theory of aging is one of the most widely acknowledged theories of aging. The intake of fruits and vegetables with antioxidant power is associated with a reduced incidence of many chronic diseases of aging. OBJECTIVE: The effects of ingesting garlic on plasma and erythrocyte antioxidant parameters of elderly subjects were investigated in this study. METHODS: 13 subjects (mean age 70.69 +/- 4.23) participated in the study. They ingested garlic at the daily dose of 0.1 g/kg b.w. for 1 month. Before and after this period, fasting blood samples were obtained, and oxidant [malondialdehyde (MDA) and xanthine oxidase (XO)] and antioxidant [superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT)] parameters were studied in erythrocytes, and MDA levels were studied in plasma samples obtained from the subjects. Routine blood biochemical parameters were also measured in blood samples. RESULTS: In the plasma fraction and erythrocyte hemolysate, MDA levels were found to be significantly lower, but erythrocyte GSH-Px and SOD activities were significantly higher in the second samples relative to the first ones. XO activity was found to be lower in the second samples, but this decrease was not statistically meaningful. LDL cholesterol was found to be significantly lower in the second samples relative to the first ones. CONCLUSION: Our results show that ingestion of garlic leads to significantly lowered plasma and erythrocyte MDA levels and to increased activities of some antioxidant enzymes, which indicates that consumption of garlic decreases oxidation reactions. It is quite possible that reduced peroxidation processes due to garlic consumption may play a part in some of the beneficial effects of garlic in elderly subjects.

OBJECTIVE: Iron deficiency in older people is common and affects physical and cognitive performance. The effects of iron deficiency on nutrition and cognitive status are well established. However, there are few studies demonstrating the impact of iron deficiency treatment on functional and cognitive outcomes in the geriatric population. The aim of this study was to determine whether iron replacement treatment was associated with an improvement in the nutritional, cognitive, and functional status of older patients with iron deficiency (ID) and iron deficiency anemia (IDA). METHODS: Geriatric patients with iron deficiency and iron deficiency anemia presenting to the geriatric clinic were included in the study. Comprehensive geriatric assessment (CGA) and blood samples to investigate iron deficiency were performed at baseline and 6 month later. 81 patients were included in the study and were evaluated at follow-up in the 6th month. The CGA included the following tests: the Katz Index of Independence in Activities of Daily Living Scale (Katz ADL), the Lawton-Brody Instrumental Activities of Daily Living Scale (IADL), the Mini-Mental State Examination (MMSE), and the Mini Nutritional Assessment Short-Form (MNA-SF), as well as the assessments of hand grip strength and walking speed. RESULTS: Of the 81 participating patients, 69.1% were women and 30.9% were men. The mean age was 76.8 ± 7.28 years. Follow-up after iron supplementation treatment was performed with a mean of 6.23 ± 1.58 months. Improvements occurred in the following geriatric and laboratory assessments: Lawton-Brody (IADL), MNA-SF, MMSE, hand grip strength, and walking speed evaluations and the levels of hemoglobin, iron, total iron-binding capacity, transferrin saturation, and ferritin. CONCLUSIONS: It was shown that iron replacement treatment has a positive impact on functional and cognitive status and nutritional parameters in older patients with ID and IDA.
RESUMEN
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 Seyranbaglari 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.

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 Seyranbaglari 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. Geriatr Gerontol Int 2016; 16: 903-910.

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.
