- Aims Safety and tolerability of prolonged supplementation with a vitamin D, calcium and leucine-enriched whey protein medical nutrition drink (WP-MND) was evaluated in sarcopenic older adults.Methods A 13-week double-blinded, randomized, isocaloric placebo-controlled trial (PROVIDE study;n = 380) was extended with a voluntary 13-week open-label extension (OLE). OLE participants were randomized to receive daily 1 or 2 servings of WP-MND (21 g protein, 3 g leucine, 10 mu g vitD and 500 mg calcium per serving). Gastro-intestinal tolerability, kidney function and serum levels of calcidiol, parathyroid hormone (PTH) and calcium were evaluated at week 0, 13 and 26.Results and discussion In response to the high daily protein intake (median1.5; IQR: 1.3, 1.7 g/kg BW/day), the estimated glomerular filtration rate (eGFR) increased in the test group during the RCT (p = 0.013). The same trend was observed for those participants with moderate chronic kidney disease. During OLE no eGFR change was observed in any of the groups. Serum calcidiol and calcium reached a plateau after 13-week WP-MND supplementation. As expected, PTH significantly changed in the opposite direction, decreasing during RCT in the test group (T vs C:p < 0.001) and during OLE in former control groups. During RCT, 20/366 participants with normal baseline calcidiol reached levels >= 100 nmol/L (T:n = 18; C:n = 2) and 6 developed albumin-corrected calcium levels > 2.55 mmol/L (T:n = 3; C:n = 3), without associated adverse events.Conclusion A 6 months intervention with up to 2 servings of WP-MND did neither result in kidney function deterioration nor symptoms of vitamin D or calcium toxicity. The product was overall well tolerated.

- Objectives: Nursing home (NH) residents are often undernourished and physically inactive, which contributes to sarcopenia and frailty. The Older Person's Exercise and Nutrition Study aimed to investigate the effects of sit-to-stand exercises (STS) integrated into daily care, combined with a protein-rich oral nutritional supplement (ONS), on physical function, nutritional status, body composition, health-related quality of life, and resource use. Design: Residents in 8 NHs were randomized by NH units into an intervention group (IG) or a control group (CG) (n = 60/group). The IG was a combination of STS (4 times/day) and ONS (2 bottles/day providing 600 kcal and 36 g protein) for 12 weeks. Setting and Participants: The participants resided in NH units (dementia and somatic care), were >= 75 years of age, and able to rise from a seated position. Methods: The 30-second Chair Stand Test was the primary outcome. Secondary outcomes were balance, walking speed, dependence in activities of daily living, nutritional status and body composition, health-related quality of life, and resource use. Results: Altogether, 102 residents (age 86 +/- 5 years, 62% female) completed the study. No improvement in the physical function assessments was observed in the IG, whereas body weight increased significantly (2.05 +/- 3.5 kg, P = .013) vs the CG. Twenty-one (of 52) participants with high adherence to the intervention (ie, at least 40% compliance to the combined intervention) increased their fat free mass (2.12 kg (0.13, 4.26 interquartile range), P = .007 vs CG). Logistic regression analyses indicated that the odds ratio for maintained/improved 30-second Chair Stand Test was 3.5 (confidence interval 1.1, 10.9, P = .034) among the participants with high adherence compared with the CG. Conclusions/Implications: Twelve-week intervention of daily STS combined with ONS in NH residents did not improve physical function, but increased body weight. Subgroup analyses indicated that high adherence to the combined intervention was associated with maintained or improved physical function and a gain of fat free mass.

- Objectives: Interindividual response variability to nutrition and exercise interventions is extensive in older adults. A group of nursing home (NH) residents participated in a combined intervention. The objective of this post-hoc analysis was to identify factors associated with intervention response measured by change in physical function and body composition. Design: Post-hoc analyses in the Older Person's Exercise and Nutrition study, a 2-arm randomized trial. The primary outcomes were 30-second Chair Stand Test and composite scores combining physical function and fat-free mass. A secondary outcome was intervention adherence. A 12-week intervention of sit-to-stand exercises and protein-rich nutritional supplements did not improve chair-stand capacity vs control on intention-to-treat basis. Setting and Participants: Residents >75 years of age from dementia and somatic units in eight NHs in Sweden. Methods: Logistic regressions were performed to define factors associated with response (maintenance/ improvement) or nonresponse (deterioration) in 30-second Chair Stand Test, and with intervention adherence. Linear regressions were performed to explore factors associated with response in composite scores. Results: Mean age of participants (n = 52 intervention, n = 49 control) was 85.8 years. Sarcopenia was occurring in 74%. Sarcopenia at baseline (P = .005) and high adherence to nutritional supplements (P = .002) increased the odds of response. Higher independence in daily activities increased the odds of adherence to sit-to-stand exercises (P =.027) and the combined intervention (P = .020). Allocation to the intervention group and higher self-perceived health were associated with higher composite scores. Conclusions and Implications: NH residents with baseline sarcopenia, better self-perceived health, and high adherence to nutritional supplements benefitted most from a combined nutrition and exercise intervention regarding chair-stand capacity and composite scores of function and fat-free mass. Adherence was related to higher grade of independence. Understanding factors associated with response and adherence to an intervention will help target susceptible residents in most need of support and to optimize the outcome.

- Background A chronic low-grade infammatory profle (CLIP) is associated with sarcopenia in older adults. Protein and Vitamin (Vit)D have immune-modulatory potential, but evidence for efects of nutritional supplementation on CLIP is limited. Aim To investigate whether 13 weeks of nutritional supplementation of VitD and leucine-enriched whey protein afected CLIP in subjects enrolled in the PROVIDE-study, as a secondary analysis. Methods Sarcopenic adults (low skeletal muscle mass) aged ≥ 65 years with mobility limitations (Short Physical Performance Battery 4–9) and a body mass index of 20–30 kg/m2 were randomly allocated to two daily servings of active (n=137, including 20 g of whey protein, 3 g of leucine and 800 IU VitD) or isocaloric control product (n=151) for a double-blind period of 13 weeks. At baseline and after 13 weeks, circulating interleukin (IL)-8, IL-1 receptor antagonist (RA), soluble tumor-necrosis-factor receptor (sTNFR)1, IL-6, high-sensitivity C-reactive protein, pre-albumin and 25-hydroxyvitamin(OH) D were measured. Data-analysis included repeated measures analysis of covariance (corrected for dietary VitD intake) and linear regression. Results IL-6 and IL-1Ra serum levels showed overall increases after 13 weeks (p=0.006 and p<0.001, respectively). For IL-6 a signifcant time × treatment interaction (p=0.046) was observed, with no signifcant change over time in the active group (p=0.155) compared to control (signifcant increase p=0.012). IL-8 showed an overall signifcant decrease (p=0.03). The change in pre-albumin was a signifcant predictor for changes in IL-6 after 13 weeks. Conclusions We conclude that 13 weeks of nutritional supplementation with VitD and leucine-enriched whey protein may attenuate the progression of CLIP in older sarcopenic persons with mobility limitations.

- Objectives: The purpose of this systematic review and meta-analysis was to summarize the prevalence of, and association between, physical frailty or sarcopenia and malnutrition in older hospitalized adults.Design: A systematic literature search was performed in 10 databases.Setting and Participants: Articles were selected that evaluated physical frailty or sarcopenia and malnutrition according to predefined criteria and cutoffs in older hospitalized patients.Measures: Data were pooled in a meta-analysis to evaluate the prevalence of prefrailty and frailty [together (pre-)frailty], sarcopenia, and risk of malnutrition and malnutrition [together (risk of) malnutrition], and the association between either (pre-)frailty or sarcopenia and (risk of) malnutrition.Results: Forty-seven articles with 18,039 patients (55% female) were included in the systematic review, and 39 articles (8868 patients, 62% female) were eligible for the meta-analysis. Pooling 11 studies (2725 patients) revealed that 84% [95% confidence interval (CI): 77%, 91%, I-2 = 98.4%] of patients were physically (pre-)frail. Pooling 15 studies (4014 patients) revealed that 37% (95% CI: 26%, 48%, I-2 = 98.6%) of patients had sarcopenia. Pooling 28 studies (7256 patients) revealed a prevalence of 66% (95% CI: 58%, 73%, I-2 = 98.6%) (risk of) malnutrition. Pooling 10 studies (2427 patients) revealed a high association [odds ratio (OR): 5.77 (95% CI: 3.88, 8.58), P < .0001, I-2 = 42.3%] and considerable overlap (49.7%) between physical (pre-)frailty and (risk of) malnutrition. Pooling 7 studies (2506 patients) revealed a high association [OR: 4.06 (95% CI: 2.43, 6.80), P < .0001, I-2 = 71.4%] and considerable overlap (41.6%) between sarcopenia and (risk of) malnutrition.Conclusions and Implications: The association between and prevalence of (pre-)frailty or sarcopenia and (risk of) malnutrition in older hospitalized adults is substantial. About half of the hospitalized older adults suffer from 2 and perhaps 3 of these debilitating conditions. Therefore, standardized screening for these conditions at hospital admission is highly warranted to guide targeted nutritional and physical interventions.
