A Randomized Controlled Pilot Trial of Interventions to Improve Functional Recovery After Hospitalization in Older Adults: Feasibility and Adherence

Improvements in sleep quality and fatigue are associated with improvements in functional recovery following hospitalization in older adults

Study objectives

Poor sleep quality, a frequent problem in older adults, has been shown to be associated with reduced physical function and wellbeing. However, little is known about the relationship between sleep quality and the recovery of physical function following hospitalization. Thus, we conducted this study to examine the association between sleep quality and functional recovery after an acute hospitalization in community dwelling older adults.

Methods

Older adult patients (N = 23, mean age = 74 ± 9 years) were recruited during an acute hospitalization (average length of stay 3.9 days) with a cardiovascular (56%), pulmonary (22%), or metabolic (13%) admission diagnosis. Objective physical function was measured using the Short Physical Performance Battery (SPPB) and self-reported function was assessed with Katz Index of Independence in Activities of Daily Living (ADL) and Lawton Instrumental Activities of Daily Living Scale (IADL). Sleep quality was measured using Pittsburgh Sleep Quality Index (PSQI) global score and Iowa Fatigue Score (IFS). Testing was performed prior to discharge (baseline) and 4-weeks post-discharge (follow-up).

Results

Regression models showed PSQI Subjective Sleep Quality change scores from baseline to 4-week follow-up predicted a change in ADL (β = -0.22); PSQI Use of Sleep Medications change scores predicted a change in SPPB Total (β = 1.62) and SPPB Chair Stand (β = 0.63); IFS change scores predicted SPPB Total (β = -0.16) and SPPB Chair Stand performance (β = -0.07) change scores.

Conclusions

For older adults, changes in sleep medication use, daytime dysfunction, and fatigue were associated with improvements in functional recovery (including physical performance and independence) from acute hospitalization to 4-week follow-up. These results suggest that interventions focused on improving sleep quality, daytime consequences, and fatigue might help enhance physical functioning following hospitalization.

Factors Affecting Engagement of Older Adults in Exercise Following Hospitalization

BACKGROUND AND PURPOSE

Exercise interventions can improve physical recovery and reduce falls in older adults following hospitalization. The aim of the study was to identify factors associated with exercise engagement after hospital discharge.

METHODS

This study was a secondary analysis of data collected as part of a randomized controlled trial. Participants were 60 years and older, discharged from 3 rehabilitation hospitals in Australia, and followed for 6 months after discharge. The primary outcome was level of engagement in exercise after discharge, measured using setting, type, frequency, and time. A secondary outcome was self-efficacy for exercise at 6-month follow-up. Data were gathered at baseline in hospital and at 6 months after discharge by telephone using structured surveys. Associations between exercise and participant characteristics were evaluated using logistic regression models.

RESULTS AND DISCUSSION

Participants' (n = 292) mean age was 78 (SD 8) years and 63% were female. There were 146 (50%) who exercised after hospitalization for a median (interquartile range) time of 60 (60-75) minutes per week. Characteristics that were significantly associated with post-discharge engagement in exercise were having higher levels of functional ability at discharge (adjusted odds ratio [AOR] 1.2, 95% CI 1.0, 1.4), living with a partner (AOR 2.9, 95% CI 1.7, 4.9), and engagement in exercise prior to hospital admission (AOR 1.7, 95% CI 1.0, 2.8). The mean self-efficacy for exercise score at 6 months post-discharge was 58.5/90 (SD 24.5). Characteristics that were significantly predictive of a higher mean self-efficacy score at 6 months after hospitalization were having a college or university education (adjusted β-coefficient [Adj β] 11.5, 95% CI 3.8, 19.0), exercise prior to hospital admission (Adj β 12.3, 95% CI 5.1, 19.5), living with a partner at discharge (Adj β 14.5, 95% CI 7.1, 21.9), and higher functional ability at discharge (Adj β 4.0, 95% CI 1.9, 6.1).

CONCLUSION

Older adults have low levels of engagement in exercise that might impact their recovery after hospitalization. During exercise prescription, clinicians should prioritize older adults who live alone, who have lower functional ability, and no previous habit of exercising.

Dietary Intake Patterns of Community-Dwelling Older Adults after Acute Hospitalization

BACKGROUND

Malnutrition and sarcopenia are a growing concern in community-dwelling older adults. Hospitalization increases the risk of malnutrition and leads to a decline in functional and nutritional status at discharge. Persistent malnutrition after hospital discharge may worsen post-hospital outcomes, including readmissions. The aim of this study was to determine dietary intakes and nutrient distribution patterns of community-dwelling older adults after acute hospitalization.

METHODS

Participants (≥65 yrs old, n=85) were enrolled during acute hospitalization and dietary 24-hour recalls were collected weekly for one month post-discharge. Analysis included: change in dietary intake over recovery timeframe; daily intake of energy, protein, fruit, vegetables, and fluids; comparison of intake to recommendations; distribution of energy and protein across mealtimes; and analysis of most common food choices.

RESULTS

Most participants did not meet current recommendations for energy, fruit, vegetables, or fluids. Average protein consumption was significantly higher than the current recommendation of 0.8g/kg/day; however only 55% of participants met this goal and less than 18% met the 1.2 g/kg/day proposed optimal protein intake for older adults. The protein distribution throughout the day was skewed and no one met the 0.4 g/meal protein recommendation at all meals.

CONCLUSIONS

Our findings indicate that community-dwelling older adults did not meet their nutritional needs during recovery after hospitalization. These data highlight the need for better nutritional evaluation and support of geriatric patients recovering from hospitalization.

Insights from an early-stage development mixed methods study on arts-based interventions for older adults following hospitalisation

BACKGROUND

A period of hospitalisation can have negative consequences on physical function and autonomy for older adults, including functional decline, dependency and reduced quality of life. Older adults favour activity that focuses on social connectedness, fun and achievable skills.

OBJECTIVE

The primary aim of this early-stage development mixed methods study was to determine the feasibility and acceptability of a randomised crossover trial design and two arts-based interventions tailored for older adults recently discharged from hospital.

MATERIALS AND METHODS

Community-dwelling adults, aged 65 years and older, who reported reduced mobility and less than six weeks post discharge from hospital were invited to participate in the study. Two sites were randomised to either a four-week dance or music therapy intervention, followed by a four-week washout and subsequently to the alternate intervention. Participants and stakeholders were interviewed to share their views and perspectives of the study design and interventions developed.

RESULTS

The arts-based interventions were acceptable and safe for participants. Randomisation was completed per protocol and no implementation issues were identified. The outcome measures used were acceptable and feasible for this group of patients and did not lead to fatigue or excessive assessment time. Participants were positive about their experience of the programme.

CONCLUSIONS

This early development study provides a precursor and several imperative learning points to guide and inform future research in the area. Difficulties in recruitment and attrition were in part due to the barriers encountered when recruiting an incident cohort of vulnerable individuals post hospitalisation.

Feasibility and preliminary effect of anabolic steroids in addition to strength training and nutritional supplement in rehabilitation of patients with hip fracture: a randomized controlled pilot trial (HIP-SAP1 trial)

Background

Anabolic steroid has been suggested as a supplement during hip fracture rehabilitation and a Cochrane Review recommended further trials. The aim was to determine feasibility and preliminary effect of a 12-week intervention consisting of anabolic steroid in addition to physiotherapy and nutritional supplement on knee-extension strength and function after hip fracture surgery.

Methods

Patients were randomized (1:1) during acute care to: 1. Anabolic steroid (Nandrolone Decanoate) or 2. Placebo (Saline). Both groups received identical physiotherapy (with strength training) and a nutritional supplement. Primary outcome was change in maximal isometric knee-extension strength from the week after surgery to 14weeks. Secondary outcomes were physical performance, patient reported outcomes and body composition.

Results

Seven hundred seventeen patients were screened, and 23 randomised (mean age 73.4years, 78% women). Target sample size was 48. Main limitations for inclusion were not home-dwelling (18%) and cognitive dysfunction (16%). Among eligible patients, the main reason for declining participation was Overwhelmed and stressed by situation (37%). Adherence to interventions was: Anabolic steroid 87%, exercise 91% and nutrition 61%. Addition of anabolic steroid showed a non-significant between-group difference in knee-extension strength in the fractured leg of 0.11 (95%CI -0.25;0.48) Nm/kg in favor of the anabolic group. Correspondingly, a non-significant between-group difference of 0.16 (95%CI -0.05;0.36) Nm/Kg was seen for the non-fractured leg. No significant between-group differences were identified for the secondary outcomes. Eighteen adverse reactions were identified (anabolic=10, control=8).

Conclusions

Early inclusion after hip fracture surgery to this trial seemed non-feasible, primarily due to slow recruitment. Although inconclusive, positive tendencies were seen for the addition of anabolic steroid.

Practical applications of whey protein in supporting skeletal muscle maintenance, recovery, and reconditioning

Like humans, many companion animals experience a gradual decline in skeletal muscle mass and function during later years of life. This process, analogous to sarcopenia in humans, increases risk for morbidity and mortality. Periods of reduced activity due to injury or illness, followed by an incomplete recovery, can accelerate the loss of muscle mass and function. Emerging research from human studies suggests that moderate amounts of high-quality protein may attenuate the loss of muscle, while preventing accumulation of fat during periods of disuse. Whey protein is a consumer-friendly and readily available source of high-quality protein. It supports skeletal muscle maintenance during normal aging and may also provide anabolic support during periods of illness, injury, and recovery. Ongoing research efforts continue to refine our understanding of how protein quality, quantity, and meal timing can be optimized to support retention of muscle mass and function during aging. Priority research areas include supplementation with high-quality protein during illness/injury to stimulate anabolism by targeting molecular mechanisms that regulate skeletal muscle metabolism.

The effect of comprehensive assessment and multi-disciplinary management for the geriatric and frail patient: A multi-center, randomized, parallel controlled trial

BACKGROUND

A comprehensive geriatric assessment (CGA) of elderly patients is useful for detecting the patients vulnerabilities. Exercise and early rehabilitation, nutritional intervention, traditional Chinese medicine (TCM), standardized medication guidance, and patient education can, separately, improve and even reverse the physical frailty status. However, the effect of combining a CGA and multi-disciplinary management on frailty in elderly patients remains unclear. The present study assessed the effects of a CGA and multi-disciplinary management on elderly patients with frailty in China.

METHODS

In this study, 320 in patients with frailty ≥70 years old will be randomly divided into an intervention group and a control group. The intervention group will be given routine management, a CGA and multi-disciplinary management involving rehabilitation exercise, diet adjustment, multi-drug evaluation, acupoint massage in TCM and patient education for 12 months, and the control group will be followed up with routine management for basic diseases. The primary outcomes are the Fried phenotype and short physical performance battery (SPPB). The secondary outcomes are the clinical frailty scale (CFS), non-elective hospital readmission, basic activities of daily living (BADL), 5-level European quality of life 5 dimensions index (EQ-5D), nutrition risk screening-2002 (NRS-2002), medical insurance expenses, fall events, and all-cause mortality. In addition, a cost-effectiveness study will be carried out.

DISCUSSION

This paper outlines the protocol for a randomized, single-blind, parallel multi-center clinical study. This protocol, if beneficial, will demonstrate the interaction of various intervention strategies, will help improve elderly frailty patients, and will be useful for clinicians, nurses, policymakers, public health authorities, and the general population.

Effects of a multicomponent high intensity exercise program on physical function and health-related quality of life in older adults with or at risk of mobility disability after discharge from hospital: a randomised controlled trial

Background

Many older people suffer from mobility limitations and reduced health-related quality of life (HRQOL) after discharge from hospital. A consensus regarding the most effective exercise-program to optimize physical function and HRQOL after discharge is lacking. This study investigates the effects of a group-based multicomponent high intensity exercise program on physical function and HRQOL in older adults with or at risk of mobility disability after discharge from hospital.

Methods

This single blinded parallel group randomised controlled trial recruited eighty-nine home dwelling older people (65–89 years) while inpatient at medical wards at a general hospital in Oslo, Norway. Baseline testing was conducted median 49 (25 percentile, 75 percentile) (26, 116) days after discharge, before randomisation to an intervention group or a control group. The intervention group performed a group-based exercise program led by a physiotherapist twice a week for 4 months. Both groups were instructed in a home-based exercise program and were encouraged to exercise according to World Health Organisation’s recommendations for physical activity in older people. The primary outcome, physical performance, was measured by the Short Physical Performance Battery (SPPB). Secondary outcomes were 6-min walk test (6MWT), Berg Balance Scale (BBS), grip strength, Body Mass Index (BMI), and HRQOL (the Short-Form 36 Health Survey (SF-36)). Data were analysed according to the intention-to-treat principle. Between-group differences were assessed using independent samples t-test.

Results

The groups were comparable at baseline. Intention-to-treat analysis showed that the intervention group improved their functional capacity (6MWT) and the physical component summary of SF-36 significantly compared to the control group. No further between group differences in change from baseline to 4 months follow-up were found.

Conclusions

A high intensity multicomponent exercise program significantly improved functional capacity and physical HRQOL in older adults with or at risk of mobility disability after discharge from hospital. The study suggests that this population can benefit from systematic group exercise after hospital-initial rehabilitation has ended.

Determinants of participation in a post-hospitalization physical exercise program for older adults

Background

Older patients often experience a decline in physical function and cognitive status after hospitalization. Although interventions involving physical exercise are effective in improving functional performance, participation in physical exercise interventions among older individuals is low. We aimed to identify factors that contribute to exercise refusal among post-hospitalized older patients.

Methods

A cross-sectional study of recruitment data from a randomized controlled trial was conducted involving 495 hospitalized people ≥70 years old. Sociodemographic and clinical data were obtained from the Basque Public Health System database. We determined physical function with the Short Physical Performance Battery (SPPB), nutritional status with the Mini-Nutritional Assessment, frailty according to the Fried phenotype criteria, and cognitive function with the Short Portable Mental Status Questionnaire (SPMSQ). Student’s t, Mann-Whitney U, or chi-squared tests were applied for bivariate analysis. Parameters significantly associated with participation were introduced in a logistic multivariate regression model.

Results

Among the analyzed patients, 88.8% declined participation in the physical exercise program. Multivariate regression revealed that older age (OR: 1.13; 95% CI: 1.07–1.19), poor nutritional status (OR: 0.81; 95% CI: 0.69–0.95), and reduced home accessibility (OR: 0.27; 95% CI: 0.08–0.94) were predictors of participation refusal. Moreover, patients who declined participation had worse performance on the SPPB (P < 0.05) and its tests of balance, leg strength, and walking speed (P < 0.05). No differences were found between groups in other variables.

Conclusions

This study confirms low participation of older adults in a post-hospitalization physical exercise program. Non-participation was associated with increased age, poor nutritional status, and reduced home accessibility. Our findings support the need for intervention design that accounts for these factors to increase older patient participation in beneficial exercise programs.

Recruitment Challenges for Low-Risk Health System Intervention Trials in Older Adults: A Case Study

OBJECTIVE

To assess factors associated with trial participation in the context of a low-risk intervention intended to reduce adverse drug events in recently hospitalized older adults.

DESIGN

Mixed methods: analysis of data collected during enrollment efforts and focus groups.

SETTING

A large, multispecialty group practice.

PARTICIPANTS

Individuals 50 years and older, recently discharged from the hospital and prescribed at least one high-risk medication, were eligible for the trial. Enrollees, decliners, and their caregivers were eligible to participate in focus groups.

MEASUREMENTS

Reasons for declining to participate during the initial invitation as well as reasons for not providing consent were recorded. Focus groups were conducted with eligible individuals to explore reasons for enrolling or declining. We conducted multivariable logistic regression to compare characteristics (including sex, age, healthcare proxy, number and type of medications, visiting nurse services, reason for admission, and length of hospital stay) of those who enrolled with those who did not enroll.

RESULTS

Of 3,606 individuals determined eligible, 3,147 (87%) declined, 98 (3%) verbally consented to participate but did not complete written consent, and 361 (10%) provided written consent and were considered enrolled. Individuals 80 year and older (odds ratio (OR) = 0.44; 95% confidence interval (CI) = 0.30-0.65) and those with visiting nurse services (OR = 0.64; 95% CI = 0.48-0.85) were least likely to enroll. Among those who provided a reason for declining (2,473), the most common was the belief they did not need additional medication assistance (18%). Another 332 (11%) declined because they were receiving visiting nurse services.

CONCLUSION

Recruiting older adults recently discharged from the hospital to participate in trials of low-risk, system-level interventions is challenging and may underenroll the oldest individuals and those potentially at the highest risk for adverse events, limiting generalizability of study findings. Alternative study designs may be more effective than individually randomized trials in assessing low-risk, system-level interventions.

Factors Associated with Step Numbers in Acutely Hospitalized Older Adults: The Hospital-Activities of Daily Living Study

OBJECTIVES

To determine the number of steps taken by older patients in hospital and 1 week after discharge; to identify factors associated with step numbers after discharge; and to examine the association between functional decline and step numbers after discharge.

DESIGN

Prospective observational cohort study conducted in 2015-2017.

SETTING AND PARTICIPANTS

Older adults (≥70 years of age) acutely hospitalized for at least 48 hours at internal, cardiology, or geriatric wards in 6 Dutch hospitals.

METHODS

Steps were counted using the Fitbit Flex accelerometer during hospitalization and 1 week after discharge. Demographic, somatic, physical, and psychosocial factors were assessed during hospitalization. Functional decline was determined 1 month after discharge using the Katz activities of daily living index.

RESULTS

The analytic sample included 188 participants [mean age (standard deviation) 79.1 (6.7)]. One month postdischarge, 33 out of 174 participants (19%) experienced functional decline. The median number of steps was 656 [interquartile range (IQR), 250-1146] at the last day of hospitalization. This increased to 1750 (IQR 675-4114) steps 1 day postdischarge, and to 1997 (IQR 938-4098) steps 7 days postdischarge. Age [β = -57.93; 95% confidence interval (CI) -111.15 to -4.71], physical performance (β = 224.95; 95% CI 117.79-332.11), and steps in hospital (β = 0.76; 95% CI 0.46-1.06) were associated with steps postdischarge. There was a significant association between step numbers after discharge and functional decline 1 month after discharge (β = -1400; 95% CI -2380 to -420; P = .005).

CONCLUSIONS AND IMPLICATIONS

Among acutely hospitalized older adults, step numbers double 1 day postdischarge, indicating that their capacity is underutilized during hospitalization. Physical performance and physical activity during hospitalization are key to increasing the number of steps postdischarge. The number of steps 1 week after discharge is a promising indicator of functional decline 1 month after discharge.

A Phase I Randomized Clinical Trial of Evidence-Based, Pragmatic Interventions to Improve Functional Recovery After Hospitalization in Geriatric Patients

BACKGROUND

Physical function declines during hospitalization in geriatric patients, increasing the risk of loss of independence. There is a need for evidence-based, pragmatic interventions to improve functional recovery of older adults following acute hospitalization. Here, we report the results of a Phase I randomized clinical trial designed to determine safety and effect size of protein supplementation, exercise, and testosterone interventions on 30-day post-discharge functional recovery and readmissions in geriatric patients.

METHODS

A total of 100 patients admitted to the University of Texas Medical Branch hospital for an acute medical illness were randomized to one of five intervention groups: isocaloric placebo, whey protein supplement, in-home rehabilitation + placebo, in-home rehabilitation + whey protein, or testosterone. Primary outcome measure was the change from baseline in short physical performance battery score at 1 and 4 weeks post-discharge. Secondary outcomes were changes in body composition, activities of daily living, and 30-day readmissions. Comparisons were made across study groups and between placebo and all active intervention groups.

RESULTS

Four weeks post-discharge, the short physical performance battery total score and balance score increased more in active intervention groups than placebo group (p < .05). There were no significant differences in change in body composition or activities of daily living across groups or between active intervention groups and placebo group. Readmission rates were highest in placebo (28%), followed by rehabilitation + placebo (15%), whey protein (12%), rehabilitation + whey protein (11%), and testosterone (5%). There was a trend for lower readmission rates in all active intervention groups (11%) versus placebo group (28%).

CONCLUSIONS

Findings from this Phase I clinical trial suggest that pragmatic, evidence-based interventions may accelerate recovery from acute hospitalization in geriatric patients. These data provide essential information to design larger randomized controlled trials to test the effectiveness of these interventions.

Effect of Aerobic Exercise Training and Essential Amino Acid Supplementation for 24 Weeks on Physical Function, Body Composition, and Muscle Metabolism in Healthy, Independent Older Adults: A Randomized Clinical Trial

BACKGROUND

Essential amino acids (EAA) and aerobic exercise (AE) acutely and independently stimulate skeletal muscle protein anabolism in older adults.

OBJECTIVE

In this Phase 1, double-blind, placebo-controlled, randomized clinical trial, we determined if chronic EAA supplementation, AE training, or a combination of the two interventions could improve muscle mass and function by stimulating muscle protein synthesis.

METHODS

We phone-screened 971, enrolled 109, and randomized 50 independent, low-active, nonfrail, and nondiabetic older adults (age 72 ± 1 years). We used a 2 × 2 factorial design. The interventions were: daily nutritional supplementation (15 g EAA or placebo) and physical activity (supervised AE training 3 days/week or monitored habitual activity) for 24 weeks. Muscle strength, physical function, body composition, and muscle protein synthesis were measured before and after the 24-week intervention.

RESULTS

Forty-five subjects completed the 24-week intervention. VO2peak and walking speed increased (p < .05) in both AE groups, irrespective of supplementation type, but muscle strength increased only in the EAA + AE group (p < .05). EAA supplementation acutely increased (p < .05) muscle protein synthesis from basal both before and after the intervention, with a larger increase in the EAA + AE group after the intervention. Total and regional lean body mass did not change significantly with any intervention.

CONCLUSIONS

In nonfrail, independent, healthy older adults AE training increased walking speed and aerobic fitness, and, when combined with EAA supplementation, it also increased muscle strength and EAA-stimulated muscle protein synthesis. These increases occurred without improvements in muscle mass.

An open-label, single-center pilot study to test the effects of an amino acid mixture in older patients admitted to internal medicine wards

OBJECTIVE

Older patients are frequently subjected to prolonged hospitalization and extended bed rest, with a negative effect on physical activity and caloric intake. This results in a consistent loss of muscle mass and function, which is associated with functional decline and high mortality. The aim of this study was to investigate the effect of 1 wk of oral amino acid (AA) supplementation in older patients subjected to low mobility during hospitalization.

METHODS

Hospitalized older patients (69-87) were included in the control group (n = 50) or were administered 25 g of AA mixture (n = 44) twice daily throughout 7 d of low mobility. We collected data related to length of stay as primary outcome measure. In-hospital mortality, 90-d postdischarge mortality, 90-d postdischarge rehospitalization, and falls also were considered. Moreover, variations of anthropometric measures, body composition and muscle architecture/strength, circulating interleukins, and oxidative stress markers between the beginning and the end of the supplementation period were analyzed as secondary outcomes.

RESULTS

Similar values were reported between the two groups regarding age (76.6 ± 6.8 versus 79 ± 7.2 y old), body weight (61.5 ± 14.3 versus 62.1 ± 16.1 kg), and body mass index (28.7 ± 4.15 versus 28.1 ± 3.62 kg/m²). Although no difference in terms of in-hospital, 90-d postdischarge, or overall mortality rate was observed between the two groups, a reduction in length of stay, 90-d postdischarge hospitalization, and falls was observed in the AA supplementation group rather than in controls. Furthermore, the AA mixture limited muscle architecture/strength impairment and circulating oxidative stress, which occurred during hospitalization-related bed rest. The latter data was associated with increased circulating levels of anti-inflammatory cytokines interleukin-4 and -10.

CONCLUSIONS

These results suggest that the AA mixture limits several alterations associated with low mobility in older hospitalized patients, such as length of stay, 90-d postdischarge hospitalization, and falls, preventing the loss of muscle function, as well as the increase of circulating interleukins and oxidative stress markers.

Preliminary effect and feasibility of physiotherapy with strength training and protein-rich nutritional supplement in combination with anabolic steroids in cross-continuum rehabilitation of patients with hip fracture: protocol for a blinded randomized controlled pilot trial (HIP-SAP1 trial)

BACKGROUND

A 2014 Cochrane review evaluating the effect of anabolic steroids after hip fracture concluded that the quality of the studies was insufficient to draw conclusions on the effects and recommended further high-quality trials in the field. Therefore, the aim of this pilot trial is to determine the preliminary effect and feasibility of a 12-week multimodal intervention consisting of physiotherapy (with strength training), protein-rich nutritional supplement and anabolic steroid on knee-extension muscle strength and function 14 weeks after hip fracture surgery.

METHODS

We plan to conduct a randomized, placebo-controlled pilot trial with 48 patients operated for acute hip fracture. The patients are randomized (1:1) to either (1) physiotherapy with protein-rich nutritional supplement plus anabolic steroid or (2) physiotherapy with protein-rich nutritional supplement plus placebo. Outcome assessments will be carried out blinded at baseline (3-10 days after surgery) and at 14 weeks after entering the trial. Primary outcome is the change from baseline to follow-up in maximal isometric knee-extension muscle strength in the fractured limb. Secondary outcomes are physical performance test, patient-reported outcomes, and measures of body composition.

DISCUSSION

If the trial is found feasible and the results show an indication of anabolic steroid being a relevant addition to further enhance the recovery of muscle strength and function in an enhanced recovery after surgery program, this trial will constitute the basis of a larger confirmatory trial.

Effects of Leucine-Enriched Whey Protein Supplementation on Physical Function in Post-Hospitalized Older Adults Participating in 12-Weeks of Resistance Training Program: A Randomized Controlled Trial

Age-related strength and muscle mass loss is further increased after acute periods of inactivity. To avoid this, resistance training has been proposed as an effective countermeasure, but the additional effect of a protein supplement is not so clear. The aim of this study was to examine the effect of a whey protein supplement enriched with leucine after resistance training on muscle mass and strength gains in a post-hospitalized elderly population. A total of 28 participants were included and allocated to either protein supplementation or placebo supplementation following resistance training for 12 weeks (2 days/week). Physical function (lower and upper body strength, aerobic capacity and the Short Physical Performance Battery (SPPB) test), mini nutritional assessment (MNA) and body composition (Dual X-ray Absorptiometry) were assessed at baseline and after 12 weeks of resistance training. Both groups showed improvements in physical function after the intervention (p < 0.01), but there were no further effects for the protein group (p > 0.05). Muscle mass did not improve after resistance training in either group (p > 0.05). In conclusion, 12 weeks of resistance training are enough to improve physical function in a post-hospitalized elderly population with no further benefits for the protein-supplemented group.

Effects of oral amino acid supplementation on Multidimensional Prognostic Index in hospitalized older patients: a multicenter randomized, double-blind, placebo-controlled pilot study

Background

It is not known whether amino acid supplementations may influence health status in hospitalized older acutely ill patients.

Aim

The aim of this study was to determine whether nutritional supplementation with amino acids (Aminoglutam^®) is associated with multidimensional improvement assessed with the Multidimensional Prognostic Index (MPI).

Methods

In this randomized, double-blind, placebo-controlled pilot clinical trial, 126 patients aged ≥65 years were enrolled from 6 Italian geriatric wards. A multidimensional assessment to calculate the MPI was performed at baseline and after 4 weeks of treatment with nutritional supplementation (96 kcal, 12 g amino acids, 0.18 g fat, 11.6 g carbohydrate, and vitamins B1, B6, and C) or placebo administered twice a day. Logistic regression modeling was applied to determine the effect of treatment on the improvement of MPI (vs no-change/worsening), adjusting for gender, age, and MPI at baseline. Treatment's interactions with age, gender, and MPI at baseline were tested adding the appropriate interaction parameter in the regression models.

Results

Of the 126 patients included, 117 patients (93%) completed the study. A significant improvement in the MPI score was detected in the overall population (mean difference post-pretreatment: -0.03, p=0.001), with no differences between active and placebo arms. Men in the amino acid supplementation group had a significantly higher rate of improvement in MPI (81%) compared to the placebo group (46%) (Fisher's exact test p=0.03). Adjusting for age, diagnosis, and MPI at baseline, amino acid treatment was shown to be associated with an improvement in MPI in men (OR=4.82, 95% confidence interval [CI]: 0.87-26.7) and not in women (OR=0.70, 95% CI: 0.27-1.81). The interaction effect between active treatment and gender was significant (p=0.04).

Conclusion

A 4-week amino acid supplementation improved the MPI significantly in hospitalized older male patients but not in female patients. Further studies are needed to confirm the gender effect of amino acid supplementation on MPI in older patients.

Protein Requirements in Critically Ill Older Adults

Critically ill elderly patients' nutritional needs are not well understood and vary with the phase of illness and recovery. Patients' nutritional needs should be assessed early in hospitalization and re-assessed throughout the stay with additional attention during the transitions from critical illness, to severe illness, to post-hospital rehabilitation. In this review, we summarize recent findings and highlight recommendations for protein supplementation in critically ill geriatric patients throughout the stages of recovery. Future research specifically focusing on protein dose, its relationship with caloric needs, and delivery modality must be conducted to provide more specific guidelines for clinical practice.
