Feasibility and Efficiency of the BEFORE (Better Exercise and Food, Better Recovery) Prehabilitation Program.

Prehabilitation has been postulated as an effective preventive intervention to reduce postoperative complications, particularly for elderly patients with a relatively high risk of complications. To date, it remains to be determined whether prehabilitation increases physical capacity and reduces postoperative complications. The aim of this study was to assess the feasibility of a 4-week multimodal prehabilitation program consisting of a personalized, supervised training program and nutritional intervention with daily fresh protein-rich food for colorectal cancer patients aged over 64 years prior to surgery. The primary outcome was the feasibility of this prehabilitation program defined as ≥80% compliance with the exercise training program and nutritional intervention. The secondary outcomes were the organizational feasibility and acceptability of the prehabilitation program. A compliance rate of ≥80% to both the exercise and nutritional intervention was accomplished by 6 patients (66.7%). Attendance of ≥80% at all 12 training sessions was achieved by 7 patients (77.8%); all patients (100%) attended ≥80% of the available training sessions. Overall, compliance with the training was 91.7%. Six patients (66.7%) accomplished compliance of ≥80% with the nutritional program. The median protein intake was 1.2 (g/kg/d). No adverse events occurred. This multimodal prehabilitation program was feasible for the majority of patients.

Multifrequency bioelectrical impedance analysis may represent a reproducible and practical tool to assess skeletal muscle mass in euvolemic acutely ill hospitalized geriatric patients.

PURPOSE: Geriatric patients with low skeletal muscle mass (SMM) and strength have a poor clinical outcome following acute illness. Consequently, it is recommended to assess SMM and strength in patients admitted to the acute care geriatric ward. Bio-impedance analysis (BIA) is a practical tool to assess SMM in hospitalized patients. However, the reproducibility of this assessment may be compromised due to changing clinical conditions. The objective was to study the reproducibility of SMM assessment using multifrequency BIA (mf-BIA) in acutely ill geriatric patients. METHODS: A total of 47 geriatric patients (age: 83 ± 7 years; n = 31 female) admitted to the acute geriatric ward participated in this pilot study. SMM was assessed on three occasions within the first week of hospital admission using the Maltron Bioscan-920-II. RESULTS: Total skeletal SMM averaged 21.4 ± 5.7, 20.7 ± 5.4, and 20.8 ± 5.1 kg assessed at 2 ± 1, 3 ± 1 and 5 ± 2 days after hospital admission, respectively. Coefficient of variation (COV) of the three SMM measurements was 4.9 ± 4.5% with an intraclass correlation coefficient (ICC) of 0.976 (CI 95%: 0.961-0.986; P < 0.001). Hydration status affected the reproducibility of the measurement, with non-euvolemic patients (n = 16) showing a significantly higher COV (7.6 ± 5.9% vs 3.5 ± 2.9%; P < 0.01) and a lower ICC (0.983 vs 0.913; P < 0.001) when compared to the euvolemic patients (n = 31). CONCLUSION: Mf-BIA seems a highly reproducible and reliable method to assess SMM throughout the first week of hospitalization in geriatric patients. However, since abnormal hydration status may compromise reliability of the measurement, assessment of SMM using mf-BIA may better be performed when euvolemic status has been established.

The Martin Vigorimeter Represents a Reliable and More Practical Tool Than the Jamar Dynamometer to Assess Handgrip Strength in the Geriatric Patient.

BACKGROUND: Geriatric patients with low skeletal muscle mass and strength generally have a relatively poor clinical outcome following acute illness. Therefore, it is recommended to routinely assess skeletal muscle mass and strength in patients admitted to the acute care geriatric ward. Handgrip strength is generally measured as a proxy for muscle strength and/or functional performance. OBJECTIVE: To compare the applicability and test-retest reliability of measuring handgrip strength using the Jamar dynamometer and the Martin Vigorimeter in geriatric patients during hospitalization. DESIGN: A total of 96 geriatric patients (age 85 ± 5 y) admitted to the acute care geriatric ward participated in this study. Handgrip strength was assessed 3 times on 2 different occasions within 1 week of hospital admission using both the Jamar dynamometer and the Martin Vigorimeter. RESULTS: Maximal handgrip strength as determined over the 3 successive attempts performed on 2 occasions averaged 17 ± 7 kg and 35 ± 13 kPa when using the Jamar dynamometer and Martin Vigorimeter, respectively. Handgrip strength was significantly greater when using the dominant versus nondominant hand using both the Jamar dynamometer (17 ± 7 kg vs 16 ± 7 kg; P = .003) and Martin Vigorimeter (34 ± 12 kPa vs 33 ± 13 kPa; P = .022). Test-retest reliability showed an ICC of 0.94 and 0.92 when applying the Jamar dynamometer or Martin Vigorimeter, respectively (both P < .001). Furthermore, handgrip strength assessed with the Jamar and Martin Vigorimeter showed a strong correlation for both the first (ρ = 0.83, P < .001) and second measurement (ρ = 0.79, P < .001). Almost 80% of the geriatric patients needed help from nursing staff with transfer from bed to an arm-rested chair measuring handgrip strength with the Jamar dynamometer according to the Southampton protocol, which is not necessary when using the Martin Vigorimeter. CONCLUSION: The Martin Vigorimeter represents a reliable and more practical tool than the Jamar dynamometer to assess handgrip strength in the geriatric patient on admission to the acute geriatric ward.

Differences in nutritional status between very mild Alzheimer's disease patients and healthy controls.

BACKGROUND: Studies on the systemic availability of nutrients and nutritional status in Alzheimer's disease (AD) are widely available, but the majority included patients in a moderate stage of AD. OBJECTIVE: This study compares the nutritional status between mild AD outpatients and healthy controls. METHODS: A subgroup of Dutch drug-naïve patients with mild AD (Mini-Mental State Examination (MMSE) ≥20) from the Souvenir II randomized controlled study (NTR1975) and a group of Dutch healthy controls were included. Nutritional status was assessed by measuring levels of several nutrients, conducting the Mini Nutritional Assessment (MNA®) questionnaire and through anthropometric measures. RESULTS: In total, data of 93 healthy cognitively intact controls (MMSE 29.0 [23.0-30.0]) and 79 very mild AD patients (MMSE = 25.0 [20.0-30.0]) were included. Plasma selenium (p < 0.001) and uridine (p = 0.046) levels were significantly lower in AD patients, with a similar trend for plasma vitamin D (p = 0.094) levels. In addition, the fatty acid profile in erythrocyte membranes was different between groups for several fatty acids. Mean MNA screening score was significantly lower in AD patients (p = 0.008), but not indicative of malnutrition risk. No significant differences were observed for other micronutrient or anthropometric parameters. CONCLUSION: In non-malnourished patients with very mild AD, lower levels of some micronutrients, a different fatty acid profile in erythrocyte membranes and a slightly but significantly lower MNA screening score were observed. This suggests that subtle differences in nutrient status are present already in a very early stage of AD and in the absence of protein/energy malnutrition.
