Assessments of functional status, comorbidities, polypharmacy, nutritional status and sarcopenia in Turkish community-dwelling male elderly

Abstract Functionality, comorbidities, polypharmacy, nutritional status and sarcopenia affect the prognosis of elderly excessively. These parameters are influenced by the population, living settings and age. We aimed to study these parameters in Turkish community-dwelling male elderly. We studied 274 male elderly ≥60 years of age admitted to our Geriatrics outpatient clinics. Mean age was 74.4 ± 7.1 years; 47.4% of the subjects were ≥75 years, 24.1% were ≥80 years. Mean activities-of-daily-living (ADL) and instrumental ADL (IADL) scores were 9.4 and 11.1, respectively. Patients with at least one-dependence at ADL–IADL were 22.6%–47.2%, and more than half-dependence at ADL–IADL were 2.8%–17.9%, respectively. Mean number of comorbidities were 2.6. Most common diagnosis was hypertension with 65%; mean number of drugs were 4.5; 55.3% were using ≥4 chronic drugs. Prevalences of malnutrition were 3.7%–6.9%, malnutrition risk were 23.5%–26.7% by the Mini Nutritional Assessment Test - Long Form and Short Form, respectively. Calf circumference was measured <31 cm in 10.5%. Our findings suggest that Turkish community-dwelling male elderly may have greater prevalences of functional dependence, sarcopenia but lower rates of malnutrition and similar rates of polypharmacy compared with the western developing countries and developed countries. This study emphasized the geographical differences in and/or between the individual countries highlighting the need for studies both country- and world-wide.

Observational cohort study on correlates of mortality in older community-dwelling outpatients: The value of functional assessment

To analyze correlates of mortality with admission features/factors in older community‐dwelling outpatients.

Predictors of treatment requirement in HBeAg-negative chronic hepatitis B patients with persistently normal alanine aminotransferase and high serum HBV DNA levels.

OBJECTIVES Serum alanine aminotransferase (ALT) is a controversial marker for disease monitoring in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) patients. The aim of this study was to determine the fibrosis stage and histological activity index (HAI) in HBeAg-negative CHB patients with persistently normal ALT (PNALT) and high serum HBV DNA (≥2000 IU/ml) and to investigate clinical risk factors for the requirement of treatment through the examination of liver biopsy specimens. METHODS HBeAg-negative CHB patients with PNALT (≤40 IU/l) and high serum HBV DNA (≥2000 IU/ml) were included. HBV fibrosis stage and HAI were scored according to the Ishak system. Multivariate logistic regression analysis was used to estimate the independent risk factors for fibrosis stage ≥2 and/or HAI ≥6. Receiver operating characteristic curve analysis was used to determine an optimal age cut-off for liver biopsy. RESULTS A total 120 patients were enrolled. These patients had a mean HBV DNA level of 123680±494500 IU/ml; the HBV DNA load was 2000-20000 IU/ml in 68 patients (56.6%) and ≥20000 IU/ml in 52 (43.4%). Eighteen patients (15%) had moderate-to-severe histological activity (HAI ≥6). Forty-three patients (35.9%) had a fibrosis stage ≥2. Forty-eight patients (40%) had a fibrosis stage ≥2 and/or HAI ≥6. On multivariate logistic regression analysis, independent variables associated with fibrosis stage ≥2 and/or HAI ≥6 included age and HBV DNA viral load. Patients with HBV DNA 2000-20000 IU/ml were more likely to require treatment compared to those with a viral load ≥20000 IU/ml. The optimal age cut-off to predict fibrosis stage ≥2 and/or HAI ≥6 was 46 years. CONCLUSIONS Significant liver damage was detected in 40% of CHB patients with PNALT and high HBV DNA upon biopsy. Age and HBV DNA viral load were independent predictors of significant liver damage. A biopsy to determine the degree of liver damage is advisable for CHB patients older than 46 years.

Body mass index and functional status in community dwelling older Turkish males

Abstract Disability is utmost important on an aging populations health. Obesity is associated with increased risk for disability. On-the-other-hand, higher-BMI is reported as associated with better functionality in older people in some reports defined as “obesity paradox”. There is some evidence on differential relationship between body weight status and functionality by living setting gender, and different populations. We studied the relation between body mass index and functionality in Turkish community dwelling older males accounting for the most confounding factors: age, multimorbidity, polypharmacy and nutritional status. This is a cross-sectional study in a geriatric outpatient clinic of a university hospital. Functionality was assessed with evaluation of activities of daily living (ADL) and instrumental activities of daily living (IADL) scales. Nutrition was assessed by mini-nutritional assessment test. Two hundred seventy-four subjects comprised our study cohort. Mean age was 74.4 ± 7.1 years, BMI was 25.8 ± 4.4 kg/m2. Linear regression analysis revealed significant and independent association of lower BMI with higher ADL and IADL scores (B = 0.047 and B = 0.128, respectively) (p < 0.05) and better nutritional status (B = 1.94 and B = 3.05, respectively) (p < 0.001) but not with the total number of medications. Higher IADL score was associated with younger age and lower total number of diseases (B = 0.121, B = 0.595, respectively) (p < 0.05) while ADL was not. We suggest that lower BMI is associated with better functional status in Turkish community-dwelling male older people. Our study recommends longitudinal studies with higher participants from different populations, genders and living settings are needed to comment more.
