Sarcopenia and mortality in older people living in a nursing home in Turkey.

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.

Evaluation of Cardiac Autonomic Functions in Older Parkinson's Disease Patients: a Cross-Sectional Study.

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.

Sarcopenia prevalence and factors associated with sarcopenia in older people living in a nursing home in Ankara Turkey.

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.

The prevalence of anemia, iron, vitamin B12, and folic acid deficiencies in community dwelling elderly in Ankara, Turkey.

OBJECTIVE: Anemia is a common problem among older people. Deficiency of essential erythropoiesis elements (iron, vitamin B12, and folic acid) is one of the major causes of anemia in older people. Studies evaluated prevalence of anemia in our country generally consisted of older people admitted to hospital. Studies conducted on community dwelling older people were much more less. The aim of this study is to evaluate prevalence of anemia and nutritional deficiencies in community dwelling elderly in our country. Totally 827 elderly individuals living in community participated in this study. MATERIALS AND METHODS: Anemia was defined according to the World Health Organization (Hb<13 g/dl for men and Hb<12 g/dl for women). Iron, vitamin B12, and folic acid deficiencies were evaluated. Iron deficiency anemia was diagnosed when anemia with iron level<60 µg/dl and ferritin level<12 ng/ml. Vitamin B12 deficiency anemia was diagnosed when anemia with vitamin B12 level<200 pg/ml. Folic acid deficiency anemia was diagnosed when anemia with folic acid level<2.6 ng/ml. RESULTS: Prevalence of anemia was found 7.3%. Prevalence of iron deficiency, vitamin B12, and folic acid deficiency were found 7.1%, 64.2% and 10.9%, and 10.9%, respectively. Prevalence of iron deficiency anemia was found 2.8%. Prevalence of vitamin B12 deficiency anemia was found 4.4% and folic acid deficiency anemia was found 1%. CONCLUSIONS: Prevalence of anemia was seen 7.3% in our study, but more studies are needed on anemia in community dwelling elderly in our country. Deficiency of iron, vitamin B12, and folic acid is also high in Turkey.

Plasma viscosity: is a biomarker for the differential diagnosis of Alzheimer's disease and vascular dementia?

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.
