Performance of Edmonton Frail Scale on frailty assessment: its association with multi-dimensional geriatric conditions assessed with specific screening tools.

BACKGROUND: The aim of this study was to evaluate the performance of Edmonton Frail Scale (EFS) on frailty assessment in association with multi-dimensional conditions assessed with specific screening tools and to explore the prevalence of frailty by gender. METHODS: We enrolled 366 hospitalised patients (women\men: 251\115), mean age 81.5 years. The EFS was given to the patients to evaluate their frailty. Then we collected data concerning cognitive status through Mini-Mental State Examination (MMSE), health status (evaluated with the number of diseases), functional independence (Barthel Index and Activities Daily Living; BI, ADL, IADL), use of drugs (counting of drugs taken every day), Mini Nutritional Assessment (MNA), Geriatric Depression Scale (GDS), Skeletal Muscle Index of sarcopenia (SMI), osteoporosis and functionality (Handgrip strength). RESULTS: According with the EFS, the 19.7% of subjects were classified as non frail, 66.4% as apparently vulnerable and 13.9% with severe frailty. The EFS scores were associated with cognition (MMSE: ß = 0.980; p < 0.01), functional independence (ADL: ß = -0.512; p < 0.00); (IADL: ß = -0.338; p < 0.01); use of medications (ß = 0.110; p < 0.01); nutrition (MNA: ß = -0.413; p < 0.01); mood (GDS: ß = -0.324; p < 0.01); functional performance (Handgrip: ß = -0.114, p < 0.01) (BI: ß = -0.037; p < 0.01), but not with number of comorbidities (ß = 0.108; p = 0.052). In osteoporotic patients versus not-osteoporotic patients the mean EFS score did not differ between groups (women: p = 0.365; men: p = 0.088), whereas in Sarcopenic versus not-Sarcopenic patients, there was a significant differences in women: p < 0.05. CONCLUSIONS: This study suggests that measuring frailty with EFS is helpful and performance tool for stratifying the state of fragility in a group of institutionalized elderly. As matter of facts the EFS has been shown to be associated with several geriatric conditions such independence, drugs assumption, mood, mental, functional and nutritional status.

Liraglutide and obesity in elderly: efficacy in fat loss and safety in order to prevent sarcopenia. A perspective case series study.

BACKGROUND: For the growing numbers of obese elderly with diabetes, the glucagon-like peptide-1 (GLP-1) receptor analogue (liraglutide) appears a safe way to promote and maintain substantial weight loss. Given this background, the aim of this study was to assess the effect of the liraglutide treatment, at doses up to 3.0 mg per day, on the body composition, focusing on sarcopenia, in overweight and obese elderly with type 2 diabetes mellitus (T2DM). METHODS: A perspective study was carried out in overweight and obese T2DM patients with HbA1c equal to 7.0 % (53 mmol/mol) ~10.0 % (86), under 3-month treatment (at least) of maximal dose of metformin at stable regime, and additional liraglutide at doses up to 3.0 mg per day. Body composition markers such as skeletal muscle index (SMI), android and gynoid fat mass, and arms and legs fat free mass, was measured by dual-energy X-ray densitometry (DXA) at baseline and after 24 weeks of liraglutide treatment. Glucose control was also carried out by glucose and HbA1c. RESULTS: Nine subjects (male/female 6/3, mean age 68.22 ± 3.86 years, BMI 32.34 ± 4.89 kg/m2) were evaluated. We noted a median decrease in BMI (-0.78 kg/m2), weight (-2000 g), fat mass (-1498 g) and android fat (-0.9 %), and a increase in SMI (+0.03 kg/m2) from baseline. Glycemic control also improved, with a median change HbA1c of -0.80 %. CONCLUSIONS: Twenty-four weeks of liraglutide treatment was associated with reductions in fat mass and android fat. In addition, in order to prevent sarcopenia, it preserved the muscular tropism.

Effects of Hazelnut Consumption on Blood Lipids and Body Weight: A Systematic Review and Bayesian Meta-Analysis.

Hazelnuts are rich in monounsaturated fatty acids and antioxidant bioactive substances: their consumption has been associated with a decreased risk of cardiovascular disease events. A systematic review and a meta-analysis was performed to combine the results from several trials and to estimate the pooled (overall) effect of hazelnuts on blood lipids and body weight outcomes. Specifically, a Bayesian random effect meta-analysis of mean differences of Δ-changes from baseline across treatment (MDΔ) (i.e., hazelnut-enriched diet vs. control diet) has been conducted. Nine studies representing 425 participants were included in the analysis. The intervention diet lasted 28-84 days with a dosage of hazelnuts ranging from 29 to 69 g/day. Out of nine studies, three randomized studies have been meta-analyzed showing a significant reduction in low-density lipoprotein (LDL) cholesterol (pooled MDΔ = -0.150 mmol/L; 95% highest posterior density interval (95%HPD) = -0.308; -0.003) in favor of a hazelnut-enriched diet. Total cholesterol showed a marked trend toward a decrease (pooled MDΔ = -0.127 mmol/L; 95%HPD = -0.284; 0.014) and high-density lipoprotein (HDL) cholesterol remained substantially stable (pooled MDΔ = 0.002 mmol/L; 95%HPD = -0.140; 0.147). No effects on triglycerides (pooled MDΔ = 0.045 mmol/L; 95%HPD = -0.195; 0.269) and body mass index (BMI) (pooled MDΔ = 0.062 kg/m²; 95%HPD = -0.293; 0.469) were found. Hazelnut-enriched diet is associated with a decrease of LDL and total cholesterol, while HDL cholesterol, triglycerides and BMI remain substantially unchanged.

MediterrAsian Diet Products That Could Raise HDL-Cholesterol: A Systematic Review.

Background. High HDL-cholesterol (HDL-C) values are negatively correlated with cardiovascular diseases. This review analyses the effect of the supplementation with various Mediterranean diet products (artichoke, bergamot, and olive oil) and Asian diet products (red yeast rice) on the HDL-C value in dyslipidemic subjects. Methods. A systematic review has been done involving all the English written studies published from the 1st of January 1958 to the 31st of March 2016. Results. The results of this systematic review indicate that the dietary supplementation with red yeast rice, bergamot, artichoke, and virgin olive oil has promising effects on the increase of HDL-C serum levels. The artichoke leaf extract and virgin olive oil appear to be particularly interesting, while bergamot extract needs further research and the effect of red yeast rice seems to be limited to patients with previous myocardial infarction. Conclusions. Various MediterrAsian diet products or natural extracts may represent a potential intervention treatment to raise HDL-C in dyslipidemic subjects.
