Abstract
BACKGROUND & AIMS There is no specific recommendation for nutrition therapy for critically ill older adults. However, targeting caloric and protein balance and avoiding fasting could improve outcomes in this high-risk nutritional population. This study aimed to evaluate the associations between nutrition and mortality/functionality in critically ill older patients. METHODS Single-center retrospective observational study of critically ill patients aged 65 years or older. We extracted data from the dietician evaluations about calories, proteins, and the type of diet (fasting, oral, enteral, parenteral) prescribed in the first week of intensive care unit admission. Primary outcomes were intrahospital mortality and independence and functional capacity evaluated after hospital discharge. RESULTS Out of the 2,043 patients screened, 533 were included in the study. Most patients were men (52.1%), with a median age of 73 (68-78) years. Overall, the intrahospital mortality rate was 53.8%. SAPS-3, albumin, C-reactive protein, and surgical patients were independently associated with fasting in a multivariate analysis. The multivariate regression analyses showed that SAPS-3, albumin, and fasting were independently associated with mortality. Each fasting day increases the risk of mortality by 16.7%. Also, independence and functional capacity were not related to nutritional prescription. CONCLUSION Older adults (65 years or older) constitute a fragile population in which nutritional breaks were associated with increased hospital mortality. Furthermore, a prospective clinical trial is necessary to establish the best strategy to feed this population. This article is protected by copyright. All rights reserved.

Abstract
Aging is associated with a progressive loss of skeletal muscle mass and function termed sarcopenia. Various metabolic alterations that occur with aging also increase the risk of undernutrition, which can worsen age-related sarcopenia. However, the impact of undernutrition on aged skeletal muscle remains largely under-researched. To build a deeper understanding of the cellular and molecular mechanisms underlying age-related sarcopenia, we characterized the undernutrition-induced changes in the skeletal muscle proteome in old rats. For this study, 20-month-old male rats were fed 50% or 100% of their spontaneous intake for 12 weeks, and proteomic analysis was performed on both slow- and fast-twitch muscles. Proteomic profiling of undernourished aged skeletal muscle revealed that undernutrition has profound effects on muscle proteome independently of its effect on muscle mass. Undernutrition-induced changes in muscle proteome appear to be muscle-type-specific: slow-twitch muscle showed a broad pattern of differential expression in proteins important for energy metabolism, whereas fast-twitch muscle mainly showed changes in protein turnover between undernourished and control rats. This first proteomic analysis of undernourished aged skeletal muscle provides new molecular-level insight to explain phenotypic changes in undernourished aged muscle. We anticipate this work as a starting point to define new biomarkers associated with undernutrition-induced muscle loss in the elderly.

Arch Gerontol Geriatr 2021; 95:104412. [PMID: 33823472 DOI: 10.1016/j.archger.2021.104412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 03/10/2021] [Accepted: 03/27/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Evidence suggests that denture non-use is significantly associated with activities of daily living, oral function, and cognitive decline. Few studies have focused on the possibility that the indications for denture use may differ depending on the cognitive and physical functions in older adults requiring long-term care. OBJECTIVES The aim of this study was to elucidate the factors associated with denture non-use in older adults requiring long-term care. METHODS This cross-sectional study comprised 201 older adults (45 men and 156 women; average age = 86.2 ± 7.1 years) requiring long-term care in Japan. Those who did not require denture treatment were classified by dentists into denture-use and denture non-use groups. The severity of dementia was assessed using the Clinical Dementia Rating scale. Multiple logistic regression analyses were conducted to detect the factors significantly associated with denture non-use. RESULTS The proportion of participants without dentures was 58.2%. Multiple logistic regression analyses revealed that a moderate dementia (odds ratio [OR], 4.44; 95% confidence interval [CI] 1.18-16.71, p=0.027) and rinsing ability (OR 3.00; 95% CI 1.12-8.06; p=0.030) were significant factors related to the non-use of dentures. CONCLUSION Severity of dementia and rinsing ability were significantly associated with non-use of dentures. These findings indicate the necessity of evaluating oral and cognitive functions while planning denture treatment in older adults requiring long-term care.

Abstract
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.

Abstract
Sufficient caloric intake is important to maintain the balanced health status, especially during the period of aging, as aging and sickness share paths. Maintaining adequate nutritional balance is the best preventive measure to counteract the risk of malnutrition. There are several causes for malnutrition in elderly people, and some techniques such as anthropometric measurements, laboratory and clinical parameters could help to diagnose malnutrition in these patients. The use of a simple validated questionnaire called the 'Mini Nutritional Assessment' measures the nutritional status of elderly patients. In this review, we discuss about the malnutrition in elderly people with and without a known cause and we present some of nutritional intervention. There are promising strategies that help overcoming malnutrition.

Abstract
BACKGROUND An adequate caloric intake is a major determinant for the health status especially when degenerative conditions become a predominant risk for difficult-to-treat diseases as in aging. METHODS A structured search of literature on the major databases was performed using terms as nutrition, elderly and malnutrition. RESULTS According to most referenced articles, it appears to be unquestionable that both organic and social risk factors [economic hardship, loneliness, institutionalization] are important as determining causes of protein-caloric malnutrition. Some anthropometric, clinical and laboratory parameters can help to make diagnosis and quantify malnutrition. However, most of them are not cheap or are not simple to perform especially in the setting of General Practice. The application of a simple questionnaire [Mini Nutritional Assessment, MNA] allows to obtain in a fast, easy and non-invasive way a valid assessment of the nutritional status in geriatric patients. The maintenance of the nutritional status is the best measure to counteract the risk of proteincaloric malnutrition and its complications which often sneakily affects elderly population and in particular frail patients. CONCLUSION This review, based on updated concepts, examines all the above mentioned points together with some aspects associated with malnutrition as an indicator of disease severity and health costs in the elderly population. Finally, the impact of nutritional intervention and nutrients supplementation on general indices of malnutrition are discussed as a promising strategy.

Abstract
The objective of this study was to examine the association between nutritional status and dietary intake in community-dwelling older adults with heart failure (HF). A cross-sectional analysis of NHANES III data was conducted. The analytic sample was comprised of n = 445 individuals aged 50+ years with congestive HF (54.4% male, 22.9% non-Hispanic Black, 43.8% low-income). Nutritional status was measured using the Prognostic Nutritional Index (PNI). Participants were classified by PNI quintiles with lower PNI scores indicating lower nutritional status. Participants in quintile 5 showed significantly greater intakes of energy, protein, vegetables, magnesium, zinc, copper, potassium, red meat, saturated fat, and sodium. In multivariate analyses, increased intake of red meat (β = 0.253, p = 0.040) and vegetables (β = 0.255, p = 0.038) was associated with significantly better nutritional status. In the absence of comprehensive nutritional guidance for HF patients, it appears that small increases in energy, protein (red meat), and vegetable consumption are associated with improved nutritional status.

Abstract
Muscle thickness, measured by ultrasonography, has been investigated for nutritional assessment in older adults, however the associations between muscle ultrasound parameters in the lower limb and nutritional status have not been studied. The aim of this study was to investigate the relationship between muscle thickness echo intensity (EI), and nutritional status in home care residents. A cross sectional study was conducted involving 19 older adults from a home care in Malaga (Spain). We evaluated lower leg muscles by ultrasound, anthropometric data, physical function (measured by gait speed and the Short Physical Performance Battery), strength (handgrip and knee extensors strength) and nutritional status across the Mini-Nutritional Assessment Short-Form (MNA-SF). We found that muscle thickness assessed by ultrasonography independently predicts nutritional status by MNA-SF and after adjusting for handgrip strength or age and sex. As secondary findings, we found relations between strength, functional capacity and the MNA-SF test. These results suggest that lower leg muscle ultrasound parameters could be used as a low-cost objective method for muscle evaluation in nutritional assessment in older adults.

Abstract
BACKGROUND Patients recently discharged from the hospital are vulnerable and are at high risk for readmission. Home-delivered meals may be beneficial in improving their health and facilitating independent living in the community. The purpose of this study was to identify the association between home-delivered meals and use of hospital services. METHODS This study includes 120 clients recently discharged from an inpatient hospital stay or from an emergency department (ED) visit who received meal services from Meals On Wheels, Inc., of Tarrant County. Healthcare utilization data was extracted from the Dallas-Fort Worth Hospital Council Foundation, a regional all claims database used by over 90% of hospitals in Dallas-Fort Worth area. Signed tests and generalized linear models (GLM) were performed. RESULTS A total of 16,959 meals were delivered from March 2013 through March 2014. Each client received an average of 6.19 meals per week. The average number of ED visits decreased from 5.03 before receipt of meals to 1.45 after receipt of meals, z = -5.23, p < .001. The average number of hospitalizations decreased from 1.33 to .83, z = -7.29, p < .001. The average length of stay per hospitalization decreased from 5.47 days to 2.34 days, z = -5.84, p < .001. Clients who received more meals were less likely to experience ED visits and hospitalizations after controlling for demographic characteristics and levels of physical functioning. CONCLUSION The findings of this study indicate that home-delivered meals services may contribute to a reduction in hospital based care services among frail and vulnerable adults. Additional studies should consider the short and long-term effects of home-delivered meals services on healthcare utilization and the potential to decrease healthcare costs.

Abstract
SCOPE One strategy to manage malnutrition in older patients is to increase protein and energy intake. Here, we evaluate the influence of protein quality during refeeding on improvement in muscle protein and energy metabolism. METHODS AND RESULTS Twenty-month-old male rats (n = 40) were fed 50% of their spontaneous intake for 12 weeks to induce malnutrition, then refed ad libitum with a standard diet enriched with casein or soluble milk proteins (22%) for 4 weeks. A 13C-valine was infused to measure muscle protein synthesis and expression of MuRF1, and MAFbx was measured to evaluate muscle proteolysis. mTOR pathway activation and mitochondrial function were assessed in muscle. Malnutrition was associated with a decrease in body weight, fat mass, and lean mass, particularly muscle mass. Malnutrition decreased muscle mTOR pathway activation and protein FSR associated with increased MuRF1 mRNA levels, and decreased mitochondrial function. The refeeding period partially restored fat mass and lean mass. Unlike the casein diet, the soluble milk protein diet improved muscle protein metabolism and mitochondrial function in old malnourished rats. CONCLUSIONS These results suggest that providing better-quality proteins during refeeding may improve efficacy of renutrition in malnourished older patients.

Abstract
AIM Physical function is considered to be associated with dysphagia: however, there is little data regarding the association between dysphagia and functional decline during hospitalization among older patients. The aim of the present study was to investigate the prevalence of dysphagia, and the association between dysphagia and functional status during hospitalization in older acute-care patients. METHODS A total of 103 older patients without present or prior history of diseases that could directly impair swallowing and cause dysphagia (45 men and 58 women; mean age 80.5 years) hospitalized in acute-care wards were included in the present study. Dysphagia or difficulty swallowing was assessed by using the 10-item Eating Assessment Tool. Functional and nutritional status, such as Barthel Index (BI), Mini-Nutritional Assessment short form, body mass index, calf circumference, handgrip strength and dysphagia, were analyzed to evaluate their relationships. RESULTS Dysphagia, as assessed using the 10-item Eating Assessment Tool, was noted in 26.2% of the participants. Multivariate analysis showed that dysphagia, handgrip strength and BI on admission were independently associated with poor BI gain during hospitalization after adjustment for age, sex, causative disease for admission, premorbid ADL, length of hospital stay, Mini-Nutritional Assessment short form, handgrip strength and BI. CONCLUSIONS Dysphagia, as assessed by the 10-item Eating Assessment Tool, was common in older patients. In addition, dysphagia was independently associated with poorer functional recovery during acute-care hospitalization of older patients. Geriatr Gerontol Int 2017; 17: 1610-1616.

Abstract
AIM This study aimed to identify factors associated with malnutrition in community-dwelling disabled elderly. METHODS A cross-sectional study of baseline data for 1,142 community-dwelling elderly (81.2±8.7 years) from of the KANAGAWA-AICHI Disabled Elderly Cohort (KAIDEC) study was conducted. The data included the participants' demographic characteristics, nutritional status (Mini Nutritional Assessment short-form: MNA-SF), dysphagia status (Dysphagia Severity scale: DSS), comorbidity, basic activities of daily living (bADL), hospitalization with in the past three months and care level according to the Long-Term Care Insurance program. The participants were considered to be in malnutrition or at risk of malnutrition if their MNA-SF score was 0-7 or 8-11, respectively. The chi square test, analysis of variance, Jonckheere-Terpstra trend test and logistic regression analysis were used for the statistical analysis. RESULTS A total of 16.7% of the participants were classified as having malnutrition. In addition, a higher prevalence of malnutrition was associated with a higher care level in the long-term care insurance program, and malnutrition was associated with a lower bADL score, the presence of dysphagia and dementia and hospitalization with in the past three months. CONCLUSIONS The present study demonstrated that malnutrition in community-dwelling disabled elderly is associated with a lower bADL score, the presence of dysphagia and dementia and hospitalization with in the past three months.

Abstract
BACKGROUND Serum selenium levels are lower in critically ill patients as compared with healthy controls. However, there is no data about the difference in serum selenium levels depending on the severity of lung diseases. We aimed to identify the factors associated with low serum selenium levels in critically ill patients with respiratory diseases. METHODS A prospective study was performed in 83 patients with respiratory diseases who had admitted to the intensive care unit (ICU) and general wards. We obtained systemic inflammatory markers, nutritional indicators and prognostic factors as the explanatory variables for the outcome of low serum selenium levels. RESULTS Serum selenium levels on admission were lower by 28% in the ICU group as compared with the general ward group (70.0±26.4 and 97.9±20.8 ng/mL, respectively, P<0.001). Low serum selenium levels had a correlation with malnutrition represented by decreases in levels of lymphocyte (R(2)=0.107, P=0.005) and albumin (R(2)=0.174, P<0.001). In addition, low serum selenium levels were associated with an increase in baseline C-reactive protein (CRP) (R(2)=0.059, P=0.041) and APACHE II scores (R(2)=0.209, P<0.001). Lower albumin levels (P=0.032) and higher APACHE II scores (P=0.046) showed a significant correlation with lower serum selenium levels on multivariate analysis. CONCLUSIONS Low serum selenium levels in patients with respiratory diseases have a significant correlation with poor nutritional status and prognosis on admission.

Prevalence of malnutrition and sarcopenia in a post-acute care geriatric unit: Applying the new ESPEN definition and EWGSOP criteria. Clin Nutr 2016; 36:1339-1344.

Abstract
BACKGROUNDS & AIMS The European Society of Clinical Nutrition and Metabolism (ESPEN) consensus definition of malnutrition has been applied in hospitalized older diabetics and middle-aged patients, geriatric outpatients, and healthy elderly and young individuals. In a post-acute care setting, our aim was to assess malnutrition (ESPEN definition) and determine its relationship with sarcopenia in older in-patients deconditioned due to an acute process. METHODS Eighty-eight in-patients aged ≥70 years with body mass index (BMI) <30 kg/m2 were included (84.1 years old; 62% women) and screened for malnutrition risk using biochemical markers and Mini-Nutritional Assessment-Short Form (MNA-SF). The ESPEN definition was applied: 1) BMI <18.5 kg/m2 or 2) unintentional weight loss plus a) low BMI or b) low fat-free mass index (FFMI). European Working Group on Sarcopenia in Older People (EWGSOP) criteria were also applied. RESULTS Unintentional weight loss occurred in 27 (30.7%) of 88 in-patients considered "at risk" by MNA-SF. Malnutrition prevalence was 4.5%, 7.9%, and 17% using ESPEN definitions 1, 2a, and 2b, respectively; 19.3% were malnourished. Prevalence of sarcopenia was 37.5%, of which 90.9% fulfilled ESPEN malnutrition criteria, a significant association (p = 0.02). No differences in biochemical markers were observed between patients with or without malnutrition or sarcopenia. CONCLUSIONS ESPEN criteria constitute an appropriate tool to establish a malnutrition diagnosis in post-acute care. Sarcopenia, as defined by EWGSOP, was present in 37.5% of patients, of which 90.9% fulfilled ESPEN criteria; therefore, malnutrition was significantly related to sarcopenia. Additional work is needed to determine further implications of the ESPEN consensus definition.

Identifying effective and feasible interventions to accelerate functional recovery from hospitalization in older adults: A randomized controlled pilot trial. Contemp Clin Trials 2016; 49:6-14.

Abstract
Hospitalization induces functional decline in older adults. Many geriatric patients fail to fully recover physical function after hospitalization, which increases the risk of frailty, disability, dependence, re-hospitalization, and mortality. There is a lack of evidence-based therapies that can be implemented following hospitalization to accelerate functional improvements. The aims of this Phase I clinical trial are to determine 1) the effect size and variability of targeted interventions in accelerating functional recovery from hospitalization and 2) the feasibility of implementing such interventions in community-dwelling older adults. Older patients (≥65years, n=100) will be recruited from a single site during hospitalization for an acute medical condition. Subjects will be randomized to one of five interventions initiated immediately upon discharge: 1. protein supplementation, 2. in-home rehabilitation plus placebo supplementation, 3. in-home rehabilitation plus protein supplementation, 4. single testosterone injection, or 5. isocaloric placebo supplementation. Testing will occur during hospitalization (baseline) and at 1 and 4weeks post-discharge. Each testing session will include measures of muscle strength, physical function/performance, body composition, and psychological function. Physical activity levels will be continuously monitored throughout study participation. Feasibility will be determined through collection of the number of eligible, contacted, and enrolled patients; intervention adherence and compliance; and reasons for declining enrollment and study withdrawal. This research will determine the feasibility of post-hospitalization strategies to improve physical function in older adults. These results will also provide a foundation for performing larger, multi-site clinical trials to improve physical function and reduce readmissions in geriatric patents.

Abstract
OBJECTIVE To assess whether the receipt of androgen therapy is associated with a reduced 30-day rehospitalization rate among older men with testosterone deficiency. PATIENTS AND METHODS We conducted a retrospective cohort study using a 5% national sample of Medicare beneficiaries. We identified 6372 nonsurgical hospitalizations between January 1, 2007, and December 31, 2012, for male patients aged 66 years and older with a previous diagnosis of testosterone deficiency. Patients who died or lost Medicare coverage in the 30 days after hospital discharge or who were discharged to another inpatient setting were excluded from the analysis. Logistic regression was used to calculate odds ratios (ORs) and 95% CIs for the risk of 30-day hospital readmissions associated with receipt of androgen therapy. RESULTS In older men with testosterone deficiency, receipt of androgen therapy was associated with a reduced risk of rehospitalization (91 of 929 androgen users [9.8%] vs 708 of 5443 non-androgen users [13.0%]; OR, 0.73; 95% CI, 0.58-0.92) in the 30 days after hospital discharge. In a logistic regression analysis adjusting for multiple demographic, clinical, and health service variables, the OR was similar (OR, 0.75; 95% CI, 0.59-0.95). The adjusted OR for unplanned 30-day hospital readmissions was 0.62 (95% CI, 0.47-0.83). Each of these findings persisted across a range of propensity score analyses-including adjustment, stratification, and inverse probability treatment weighting-and several sensitivity analyses. CONCLUSION Androgen therapy may reduce the risk of rehospitalization in older men with testosterone deficiency. Given the high rates of early hospital readmission among older adults, further exploration of this intervention holds broad clinical and public health relevance.

Abstract
About half of all cancer patients show a syndrome of cachexia, characterized by anorexia and loss of adipose tissue and skeletal muscle mass. Cachexia can have a profound impact on quality of life, symptom burden, and a patient's sense of dignity. It is a very serious complication, as weight loss during cancer treatment is associated with more chemotherapy-related side effects, fewer completed cycles of chemotherapy, and decreased survival rates. Numerous cytokines have been postulated to play a role in the etiology of cancer cachexia. Cytokines can elicit effects that mimic leptin signaling and suppress orexigenic ghrelin and neuropeptide Y (NPY) signaling, inducing sustained anorexia and cachexia not accompanied by the usual compensatory response. Furthermore, cytokines have been implicated in the induction of cancer-related muscle wasting. Cytokine-induced skeletal muscle wasting is probably a multifactorial process, which involves a protein synthesis inhibition, an increase in protein degradation, or a combination of both. The best treatment of the cachectic syndrome is a multifactorial approach. Many drugs including appetite stimulants, thalidomide, cytokine inhibitors, steroids, nonsteroidal anti-inflammatory drugs, branched-chain amino acids, eicosapentaenoic acid, and antiserotoninergic drugs have been proposed and used in clinical trials, while others are still under investigation using experimental animals. There is a growing awareness of the positive impact of supportive care measures and development of promising novel pharmaceutical agents for cachexia. While there has been great progress in understanding the underlying biological mechanisms of cachexia, health care providers must also recognize the psychosocial and biomedical impact cachexia can have.

Abstract
OBJECTIVES High rates of malnutrition have been reported in the older hospitalized patient population. This is recognised to impact on patient outcomes and health costs. This study aimed to assess the impact of nutrition screening and intervention on these parameters. DESIGN Randomised controlled prospective study. SETTING The study was performed in the acute geriatric medicine wards of the Prince of Wales Hospital, Sydney Australia. PARTICIPANTS All patients admitted to these wards under a geriatrician with an expected length of stay of at least 72 hours were considered for the study. INTERVENTION Patients were screened on admission for malnutrition using the Mini Nutritional Assessment (MNA) tool and randomly assigned to control or intervention groups. Intervention patients were immediately commenced on a malnutrition care plan (MCP). Control patients were only commenced on a MCP if referred by clinical staff. MEASUREMENTS Length of stay (LOS), weight change and frequency of readmission to hospital were compared between the groups. RESULTS 143 patients were screened. 119 were identified as malnourished (MN) or at risk of malnutrition (AR). Overall LOS was not different between the two groups (control v. intervention: 13.4 ± 1.3 days v. 12.5 ± 1.2 days, p=0.64). However there was a significant decrease in LOS in the MN (control v. intervention: 19.5 ± 3 days v. 10.6 ± 1.6 days, p=0.013) and a trend to reduced readmissions. There was no difference in weight change over admission between the groups. Without screening, clinical staff identified only a small proportion of malnourished patients (35% of MN and 20% of AR). CONCLUSIONS Malnutrition in the older hospital population is common. Malnutrition screening on hospital admission facilitated targeted nutrition intervention, however length of stay and re-presentations were only reduced in older malnourished patients with an MNA score less than 17.

Abstract
BACKGROUND/OBJECTIVES Routine nutrition screening is recommended for all older patients admitted to hospital however data on the prevalence of malnutrition in rehabilitation settings is sparse. This study assessed the nutritional status of older patients admitted to rehabilitation hospitals over a 5 year period and described the association between nutritional status and length of hospital stay (LOS) in this context. The usefulness of a recently revised version of the shortened MNA (MNA-SF) was also investigated. METHODS A retrospective analysis was conducted of patients aged 65 + y admitted to two rehabilitation hospitals in New South Wales, Australia between 1st March 2003-30th June 2004, and 11th January 2005-10th December 2008. Nutritional status was determined on admission by trained dietitians using the full MNA instrument and the MNA-SF. Information on diagnosis-related grouping and length of stay (LOS) was obtained. RESULTS Data was available for 2076 patients with a mean age of 80.6 (27.7) y. Thirty-three percent and 51.5% of patients were classified as malnourished and at nutritional risk, respectively. Controlling for date of admission and diagnosis related grouping, LOS was higher in malnourished and at risk groups compared to their well nourished peers (P < 0.001) by 18.5 and 12.4 days, respectively. MNA-SF demonstrated high sensitivity but relatively low specificity against the full MNA. CONCLUSION The majority of older patients in the rehabilitation setting are nutritionally compromised which adversely influences LOS. In order to encourage more widespread screening, the MNA-SF may be able to replace the full MNA.

Abstract
Aging is associated with decreased food intake, a phenomenon termed the anorexia of aging. In this study, we sought to clarify changes in peripheral and central appetite-related factors in aged mice. Furthermore, we investigated the effects of rikkunshito, a traditional Japanese medicine, on age-related anorexia. C57BL/6J mice that were 6 or 75 wk old were studied. We investigated changes in food intake, ghrelin and leptin levels, and the expression of appetite-related genes with age. In addition, we verified the effects of ghrelin, rikkunshito, phosphodiesterase 3 (PDE3), and phosphoinositide 3-kinase inhibitors on appetite. Food intake was significantly decreased in 75-wk-old mice compared with the 6-wk-old mice. In 75-wk-old mice, plasma acylated ghrelin levels under fasting conditions were lower than in 6-wk-old mice, whereas leptin levels under feeding conditions were substantially higher. The expression levels of hypothalamic preproghrelin under feeding conditions and the expression levels of neuropeptide Y and agouti-related protein under fasting conditions were lower compared with those of the 6-wk-old mice. Ghrelin supplementation (33 microg/kg) failed to increase food intake in 75-wk-old mice. Conversely, oral administration of LY294002, a phosphoinositide 3-kinase inhibitor, and cilostamide, a PDE3 inhibitor, increased food intake in 75-wk-old mice. Moreover, rikkunshito increased food intake in aged mice. The components of rikkunshito (nobiletin, isoliquiritigenin, and heptamethoxyflavone) had inhibitory effects on PDE3. These results suggest that dysregulation of ghrelin secretion and ghrelin resistance in the appetite control system occurred in aged mice and that rikkunshito ameliorated aging-associated anorexia via inhibition of PDE3.

Abstract
BACKGROUND AND AIMS The number of hospital admissions of the elderly is increasing and hospitalization often leads to functional decline. The aim of this study was to identify major risk factors for functional decline in the hospitalized oldest old. METHODS Prospective, observational, non-randomized study of patients aged >/=80 years, admitted for at least two days to the University Department of Geriatric Medicine of Torino, Italy, between November 2003 and November 2004. For detection of functional decline, the ADL scale was used, referring to the number of dependent ADL. RESULTS At discharge, ADL mean scores were significantly higher than on admission (2.5+/-2 vs 2.3+/-1.9, p<0.001). 23.9% of the sample lost at least one ADL function during hospitalization, and 19.2% were transferred to long-term care, compared with 5.4% of those with no functional decline. Length of hospitalization, neoplasm, low level of albumin and high number of drugs prescribed were associated with functional decline. At multivariate analysis, only in-hospital stay was an independent risk factor for functional decline (RR 1.1 per day of hospitalization, CI 1.03-1.14). CONCLUSIONS Hospitalization of the oldest old increases the risk of functional decline, especially if prolonged. It is important to identify patients at high risk for functional decline after hospital admission.

Abstract
Background Staphylococcus aureus methicillin-resistant (MRSA) has been frequently isolated from endotracheal and lung puncture aspirates in malnourished children with pneumonia. In this work we evaluated the susceptibility of undernourished BALB/c mice and its ability to mount a protective immunity against MRSA with emphasis on the lung involvement. Results BALB/c mice submitted to a 20% dietary restriction during 20 days presented a significant decrease in body weight, lymphocyte number and also atrophy in thymus and intestinal epithelium. Determination of bacterial load by the number of colony forming units (CFU) indicated a similar susceptibility whereas the findings of Gram stain clearly suggested a higher amount of bacteria in the lungs of normal mice than in the undernourished ones. Immunization reduced bacterial growth in the lungs of normal mice but not in the undernourished ones. Histopathological analysis showed that inflammation appeared in the lungs from normal mice only after infection and that immunization prevented this pulmonary inflammatory process. On the other hand, undernourished mice presented lung inflammation even before infection. In addition, the degree of this inflammatory process did not change with infection or previous immunization. Conclusion Our results indicated that lung injury during MRSA infection is prevented by previous immunization in well nourished but not in undernourished mice.

Abstract
OBJECTIVES To determine the cut off score of the CNS in predicting 12 months mortality. DESIGN Data was collected and followed up from a previous study among elderly subjects (n = 515) living in community institutional setting. The risk of malnutrition and 12 months mortality was ranked by the CNS and compared with that by SGA. Reliability was assessed by the sensitivity and specificity of the prediction with SGA as well as BMI alone. Sensitivity and specificity was calculated to determine validity as well as using positive and negative predictive values in predicting mortality at 12 months. RESULTS All three tools (BMI, SGA, CNS) demonstrated significant difference of higher mortality rate (P < .001) in the malnourished group. CNS at score < or = 21 showed comparable results to SGA tool and BMI at classifying malnutrition. And using cut off score > or = 22 also show significant results with SGA in classifying patients with normal nutrition. CNS score at > or = 22 sensitivity was 60.9% and specificity was 72.9% with a Negative Predictive value of 92.3% and a Positive Predictive value of 25.8%. CONCLUSION CNS tool at cut off > or = 22 is just as good as using BMI or SGA in identifying those who have a normal nutritional status. This is useful in particular, when biochemical or anthropometric data is not available. This further validates the use of > or = 22 as the best cut off point with the CNS tool and just as good at predicting of mortality when compared with SGA and BMI assessments.

Abstract
BACKGROUND AND AIMS Protein and/or energy malnutrition is common in hospitalized older patients and is associated with poor outcomes. Among recommended nutritional screening tools, contrasting data exist about the usefulness of the Mini Nutritional Assessment Short-Form (MNA-SF). We evaluated whether the MNA-SF, alone or integrated with serum albumin levels, is a reliable predictor of functional decline in older patients. METHODS We studied 275 elderly patients (mean age 76.5, 60.7% males) admitted to an acute medical ward of a tertiary-care teaching hospital over a 12-month period. In this observational study, we evaluated nutritional status, with the MNA-SF alone or integrated with albumin. Data were collected at admission and related to laboratory and geriatric assessment features, and length of stay (LOS). Functional decline (defined as a loss >or=10% in terms of Barthel Index score at discharge compared with 2 weeks before admission) was considered as outcome. RESULTS The MNA-SF estimated 46% patients at risk of malnutrition. These subjects had worse clinical features (lower total cholesterol and albumin levels), longer LOS (13.3 vs 11.2 days, p=0.014) and considerable functional decline (OR 4.25, 95% CI 1.83-9.9, p=0.001). Integrating the MNA-SF with albumin values, we obtained an effective instrument to detect older inpatients with protein-energy malnutrition, at higher risk of undergoing functional decline (OR 16.19, 95% CI 4.68-56.03, p<0.0001). CONCLUSIONS The MNA-SF is a useful screening tool for hospitalized elders at risk of malnutrition. It is associated with poor clinical outcomes and is able to predict functional decline. Together with hypoalbuminemia, it better identifies patients with true protein-energy malnutrition.

Abstract
OBJECTIVES To test the effect of nutritional support on older patient's quality of life. DESIGN Double-blind, randomized, placebo-controlled trial conducted from March 2001 to January 2004. SETTING United Kingdom. PARTICIPANTS Two hundred twenty-five hospitalized acutely ill older patients. INTERVENTION Normal hospital diet plus 400-mL oral nutritional supplements daily for 6 weeks. The composition of the supplement was such as to provide 995 kcal for energy and 100% of the Reference Nutrient Intakes for a healthy older person for vitamins and minerals. MEASUREMENTS Baseline, 6-week, and 6-month nutritional status and quality of life. RESULTS Randomization to the supplement group led to significantly better quality-of-life scores than in the placebo group at 6 months but not at 6 weeks, after adjustment for baseline quality of life, age, and sex. The effect of supplementation was seen in higher physical function, role physical, and social function scores. Corresponding treatment effects were 7.0 (95% confidence interval (CI)=0.5-13.6, P=.04), 10.2 (95% CI=0.1-20.2, P=.047), and 7.8 (95% CI=0.0-15.5, P=.05), respectively. There was no evidence of difference in Barthel scores at 6 months. CONCLUSION Oral nutritional supplementation of acutely ill hospitalized older patients led to a statistically significant benefit in quality of life.

Abstract
Four hundred and forty-five randomly selected hospitalised patients had their nutritional status assessed from anthropometric, haematological and biochemical data. Nutritional status was compared between survivors and non-survivors at baseline, 6 weeks and 6 months. Using Cox's proportional hazard analysis, we measured the association between nutritional assessment variables and 1-year mortality after adjusting for disability, chronic illness, medications, smoking and tissue inflammation. Nutritional status was significantly worse amongst non-survivors compared with survivors, and non-survivors showed marked and significant deterioration in all measures of nutritional status compared with survivors. After adjusting for poor prognostic indicators the hazard ratios of death in the fourth, third and second quarters of both baseline serum albumin and mid-upper arm circumference distributions relative to the first were 0.68, 0.77 and 0.58 (trend P = 0.013) and 0.61, 1.0 and 0.87 (trend P = 0.005) respectively. Intervention studies are needed to determine whether the relationship between malnutrition and the poor outcome highlighted by the present study is causal or a mere association.

Abstract
Undernutrition profoundly affects immune responses, particularly at the extremities of life: in infants and in the elderly. The present review focuses on this interrelationship in the elderly. It describes three different stages of ageing: stage 1, healthy ageing, which is observed in very healthy elderly individuals who have no nutritional deficit; stage 2, common ageing, which is observed in most elderly individuals in whom various micronutrient deficits are found; stage 3, pathological ageing, which is observed in patients with protein–energy deficiency. Stage 1, primary immune ageing, is essentially characterized by changes in T-cell subsets but no change in T-cell function; T-cell function is reduced only in the very elderly (>90 years old). Stage 2, secondary immune ageing, is influenced by micronutrient deficits that may be corrected by providing nutritional supplements. Furthermore, immune responses may also be enhanced by supplementation of subjects who have no micronutrient deficits, indicating that the immune system of elderly individuals is highly susceptible to the influence of micronutrients. In stage 3, tertiary immune ageing, the immune responses are strongly related to the decreased nutritional status. In these patients decreased immune responses lead to long-lasting acute-phase responses, which induce greater use of nutritional reserves during disease and lead to increased frailty. As nutritional status has a marked effect on immune responses in elderly individuals, nutritional therapy should be given to elderly individuals who have nutrient deficits, and perhaps also to individuals who do not have nutrient deficits in order to promote healthy ageing and extend the lifespan.

Abstract
AIM This study aimed to evaluate the relationship between anthropometric measurements and mortality among community-dwelling frail elderly. METHODS This study was a prospective cohort analysis of 520 community-dwelling elderly registered in the Nagoya Longitudinal Study for Frail Elderly (NLS-FE). Data included the participants' demographic characteristics, body mass index (BMI), mid-arm circumference (MAC), triceps skinfold (TSF), and arm muscle area (AMA), basic activities of daily living, comorbidity. BMI and TSF values were categorized into three groups, respectively, according to above the 75th percentile, the 25-75th percentile, and below the 25th percentile of Japanese Anthropometric Reference Data (JARD 2001). Survival analysis of 21-month mortality was conducted using Kaplan-Meier curves and multivariate Cox proportional hazards models. RESULTS BMI and TSF were independent risk factors for 21-month mortality in the study participants. Significant higher risk of 21-month mortality was observed in participants below the 75th percentile of BMI or below the 25th percentile of TSF set in JARD 2001. A striking increase in the risk of 21-month mortality, adjusting for potential confounding factors, was observed in the below 75th percentile of the BMI group with a below 25th percentile TSF of JARD 2001, compared with the 75th or above percentile BMI group with the 25th or above percentile TSF. CONCLUSION The combination of BMI and TSF is a predictor of 21-month mortality among older people with ADL dysfunction.

Abstract
Modular protein supplements are added to either the diet or enteral formula to increase the protein or amino acid intakes of people who are nutritionally compromised. Protein supplements are aggressively marketed to long-term care clinicians because protein energy malnutrition and wounds are a common problem in this care setting. It can be challenging for clinicians to distinguish one product from another and to determine the best product for a specific application or nutrition care goal. Modular protein products can be sorted into 4 categories: (1) protein concentrates derived from a complete protein such as milk, soy, or eggs; (2) protein concentrates derived from collagen, either alone or in combination with a complete protein; (3) doses of 1 or more dispensable (nonessential) amino acids; and (4) hybrids of the complete or collagen-based proteins and amino acid dose. Modular protein supplements are generally provided either as a substrate for protein synthesis or as a source of 1 or more amino acids that may be conditionally indispensable (conditionally essential) under certain disease conditions. This review provides guidelines for the use of modular protein supplements according to their intended physiologic function and the assessment and nutrition care goals of the long-term care resident.

Abstract
Nutrition is an important issue in institutional care, and is related to clinical outcomes in many aspects. Although Taiwan is marching to an aged society, related studies were lacking. Elderly residents in two long-term care facilities (LTCF) were enrolled for study. Nutritional status including anthropometric measurements and laboratory examinations was assessed every 3 months for 12 months. Age, sex-matched community-dwelling elderly participating in the annual health check-up was randomly selected as the control subjects. In total, 66 subjects in LTCF and 870 age, sex-matched community-dwelling elderly were enrolled. Body mass index, serum levels of albumin, and total cholesterol were significantly poorer in LTCF residents than the community-dwelling elderly. Triceps skinfold thickness, hemoglobin, serum albumin, and total cholesterol were progressively deteriorated among the institutionalized elderly during the 6-month follow-up. Thirteen subjects of the study group had been hospitalized during the follow-up. Body mass index, triceps skinfold thickness, mid-arm circumference, serum albumin at screening were significantly poorer and unintentional weight loss within 6 months was significantly greater in subjects who had been hospitalized. By using multivariate logistic regression model, only weight loss >5% within 6-month follow-up was the significant independent predictive factors to hospitalization. In conclusion, nutritional status of institutionalized elderly Chinese was significantly poorer than the community-dwelling elderly. Nutritional markers were progressively deteriorated in LTCF residents during the follow-up period. Unintentional weight loss >5% within 6 months was the only significantly independent predictive factor for hospitalization among the institutionalized elderly Chinese.

Abstract
Protein energy malnutrition is common in the elderly, especially in hospitalized patients. The development of strategies designed to correct such malnutrition is essential. Our working hypothesis was that poor response to nutrition with advancing age might be related to splanchnic sequestration of amino acids, which implies that fewer amino acids reach the systemic circulation. Administration of citrulline, which is not taken up by the liver, can offer a means of increasing whole body nitrogen availability and, hence, improve nutritional status. Thirty old (19 mo) rats were submitted to dietary restriction (50% of food intake) for 12 wk. They were randomized into three groups: 10 rats (R group) were killed and 20 others refed (90% of food intake) for 1 wk with a standard diet (NEAA group) or a citrulline-supplemented diet (Cit group). Before being killed, the rats were injected with [(13)C]valine, and the absolute protein synthesis rate (ASR) was measured in the tibialis using the flooding-dose method. When the rats were killed, the tibialis was removed for protein content analysis. Blood was sampled for amino acid and insulin analysis. The standard diet did not have any effect on protein synthesis or on the protein content in the muscle. Citrulline supplementation led to higher protein synthesis and protein content in muscle (117 +/- 9, 120 +/- 14, and 163 +/- 4 mg/organ for protein content in R, NEAA, and Cit groups, P < 0.05). The ASR were 0.30 +/- 0.04, 0.31 +/- 0.04, and 0.56 +/- 0.10 mg/h in the three groups, respectively (R and NEAA vs. Cit, P < 0.05). Insulinemia was significantly higher in the Cit group. For the first time, a realistic therapeutic approach is proposed to improve muscle protein content in muscle in frail state related to malnutrition in aging.

Abstract
PURPOSE The study tested whether nutritional support of older patients during acute illness leads to a clinical benefit. METHODS In this randomized, double-blind, placebo-controlled study, we randomly assigned 445 hospitalized patients aged 65 to 92 years to receive either a normal hospital diet plus 400 mL oral nutritional supplements (223 subjects) or a normal hospital diet plus a placebo (222 subjects) daily for 6 weeks. The composition of the supplement was such as to provide 995 kcal of energy and 100% of the Reference Nutrient Intakes for vitamins and minerals for a healthy older person. Patients had three assessments: at baseline, at 6 weeks, and at 6 months post-randomization. Outcome measures were 6 months of disability, non-elective readmission and length of hospital stay, discharge destination, morbidity, and mortality. RESULTS Randomization to the supplement group led to a significant improvement in nutritional status. Over 6 months, 65 patients (29%) in the supplements group were readmitted to the hospital compared with 89 patients (40%) in the placebo group (adjusted hazard ratio 0.68 [95% confidence interval 0.49-0.94]). The mean length of hospital stay was 9.4 days in the supplements group compared with 10.1 days in the placebo group. Thirty-two people (14%) died in the supplement group compared with 19 people (9%) in the placebo group at 6 months (adjusted hazard ratio 1.65 [95% confidence interval, 0.93-2.92]). CONCLUSION Oral nutritional supplementation of acutely ill patients improved nutritional status and led to a statistically significant reduction in the number of non-elective readmissions.

Abstract
Current nutritional care provision to 1905 patients hospitalized in 12 Cuban hospitals is presented in this article, diagnosed after conducting the Hospital Nutrition Survey (HNS), as part of the activities comprising the Cuban Study of Hospital Malnutrition (Elan-Cuba). The obtained HNS results were contrasted with standards regarding the nutritional assessment of hospitalized patient, the diagnosis of nutritional disorders occurring in the patient, and the identification of patients in need of nutritional intervention. The Elan-Cuba Study returned a 41.2% malnutrition rate [Barreto Penié J, Cuban Group for the Study of Hospital Malnutrition. State of malnutrition in Cuban hospitals. Nutrition 2005;21:487-97]. However, malnutrition was recorded as an independent diagnosis in only 0.4% of the surveyed clinical charts. It could not be shown that medical care teams were systematically applying any of the techniques and procedures recommended for the assessment of the nutritional status of hospitalized patients. In the best of the cases, only 40.6% of the surveyed patients had their height and weight recorded in their clinical charts at admission, 9.0% of those with more than 15 days of hospitalization had a prospective value of weight, and less than 20.0% of them had their serum albumin levels and/or their counts of Lymphocytes annotated on their clinical charts. Although 10.9% of the surveyed patients (median of the subcategories values; range: 3.5-41.2%) fulfilled an indication for nutritional intervention, support (enteral and/or parenteral) was only provided to less than 15.0% of them, with the exception made of patients on NPO, of whom 32.3% received either of the two modes of artificial nutrition listed above. It is to be noticed that none of the patients with chronic organic failure were on nutritional support at the time of the survey. The current nutritional care provision to the hospitalized patient might explain the increased rates of hospital malnutrition documented in the Elan-Cuba Study, and should lead to the design and urgent implementation of nutritional and metabolic intervention programs in the surveyed hospitals, given the deleterious effects of nutritional disorders upon the ultimate results of the medical and surgical actions, and the quality and costs of medical care.

Abstract
OBJECTIVE In the clinical practice, visceral proteins are used as indirect markers of protein energy malnutrition (PEM), but their reliability could be reduced with advancing age. The aim of this work is to investigate the reliability of albumin, prealbumin, retinol-binding protein (RBP) and transferrin in evaluating nutritional status in old patients and their relationship with fat-free mass (FFM). DESIGN Cross-sectional study. SETTING Padua, Italy. SUBJECTS In 44 underweight (body mass index < 20 kg/m(2)) (66-97 years) and 69 normal weight or overweight elderly subjects (62-98 years), albumin, prealbumin, transferrin and RBP were determined in the plasma. Body composition and particularly FFM was obtained by dual X-ray absorptiometry. FFM was also expressed as FFM index (FFMI) calculated as FFM divided by height squared. Subjects affected by acute illnesses and inflammatory states were excluded. RESULTS Albumin, prealbumin and RBP mean values were significantly lower in underweight subjects. No differences between two groups were found for transferrin. Albumin prealbumin and RBP resulted under the normal range in 55, 25 and 54% of underweight subjects, respectively. Transferrin's values were low in about 40% of underweight and normal weight subjects, respectively. In all subjects, FFMI shows a significant correlation with albumin (r: 0.52), prealbumin (r: 0.64) and RBP (r: 0.57). No correlation between FFMI and transferrin was found. CONCLUSIONS Visceral proteins, except for transferrin, seem to be useful indexes in detecting malnutrition in the elderly; low values still in the normal range should also be carefully evaluated because they could suggest a poor nutritional status.

Abstract
Objective To measure energy expenditure of acutely ill elderly patients in hospital and following discharge in the community. Design Sixty-three consecutive hospitalised acutely ill elderly patients were recruited. Eight patients were studied to assess the reliability of the Delta Tract Machine as a measure of energy expenditure; 35 patients had their energy expenditure studied in hospital on two occasions and 20 patients had their energy expenditure measured in hospital and at 6 weeks in the community Results Men had higher basal energy expenditure (BMR) values compared to women however the difference was not statistically significant [Men, mean (SD) 1405 (321) Kcal, women 1238 (322) kcal; mean difference (95% CI) 166 kcal (-17 to 531), p = 0.075]. After adjusting for age, gender and body mass index both medication and C-reactive protein (CRP), concentrations showed significant correlation with measured energy expenditure in hospital, (r = -0.36, "p < 0.05"; r = -0.29, "p < 0.05" respectively). However, in a multivariate analysis for all 63 subjects combined CRP explained most of the variance in BMR in hospital. The Harris Benedict equation predicted within ± 10% measured BMR in only 47% of individuals in hospital. Conclusion Tissue inflammation and medications were associated with change in measured energy expenditure in acutely ill patients.

Abstract
With the aging of the Canadian population, functional autonomy and quality of life among seniors are now important public health issues. We hypothesized that nutrition is an important determinant of the quality of aging because of its potential to modulate the transitions from vulnerability to frailty and dependence. Over the past 15 years, our research program addressed the prevalence, the determinants, and the consequences of undernutrition among seniors, especially the free-living frail elderly. Very low energy and nutrient intakes were observed as well as a high prevalence of involuntary weight loss. These chronic conditions were associated with early institutionalization and increased mortality rates. Intervention strategies were then developed and evaluated, including the Nutrition Screening Program and the Nutrition Support Program. The effectiveness of these programs was shown with respect to improvement of nutritional status. However, this improvement was not sufficient to produce significant changes in functional autonomy or quality of life. Methodological issues related to the conduct of intervention studies in this specific population were addressed. A conceptual framework of nutritional intervention is currently being validated. A large longitudinal study that is being undertaken will further contribute to our understanding of the aging process as determined by a modifiable factor such as nutrition.Key words: aging, nutrition, autonomy, nutrition screening, nutrition intervention.

Abstract
PURPOSE Determine the independent and combined effects of progressive resistance muscle strength training (PRMST) and testosterone on strength, muscle mass, and function in hypogonadal elderly male recuperative care patients. METHODS Between 1999 and 2004, 71 subjects (mean age 78.2 +/- 6.4 yr, 86% white) were enrolled. After baseline one-repetition maximum (1RM) strength testing and then randomization to one of four treatment groups (low-resistance (20% of the 1RM) exercises and weekly injections of either 100 mg of testosterone enanthate or placebo or high-intensity PRMST (> or =80% 1RM) and weekly injections), each subject received training and injections for 12 wk. RESULTS Ten subjects withdrew from the study before its completion. Based on intent-to-treat analyses, strength improved in all groups, but was greater with high-intensity PRMST compared with low-resistance exercise (e.g., leg press, (mean +/- SE), 28 +/- 4 vs 13 +/- 4%, P = 0.009). Although testosterone led to significantly greater increases in midthigh cross-sectional muscle area compared with placebo (7.9 +/- 1.3 vs 2.4 +/- 1.4%, P = 0.005), it produced only a nonsignificant trend toward greater strength gains (e.g., leg press 25 +/- 4 vs 16 +/- 4%, P = 0.144). Change in aggregate functional performance score (the sum of 4 functional performance test scores) did not differ between the four intervention groups nor with high-intensity PRMST compared with low-resistance exercise (7 +/- 5 vs 15 +/- 5%, P = 0.263). There was not a significant interaction between exercise and testosterone for any outcome. CONCLUSION High-intensity PRMST is as safe and well tolerated as a similarly structured low-resistance exercise regimen for very frail elderly patients, but produces greater muscle strength improvements. The addition of testosterone leads to greater muscle size and a trend toward greater strength but did not produce a synergistic interaction with exercise. Neither intervention had a significant effect on functional performance.

Abstract
Undernutrition contributes to poor clinical outcomes in hospitalised elderly patients but the potential impact of oral nutritional supplements may be reduced by suppressing subsequent food intake. We investigated this possibility in elderly female patients recovering mainly from hip fracture by studying the effect of oral supplements on subsequent food intake during an ad libitum buffet luncheon meal. We tested the effect in seven women by giving the supplement 90 min before the meal and compared energy and macronutrient intake with a control water pre-load condition. A similar study was carried out in another seven women with the supplement or water drink given 30 min beforehand. Both self-rated appetite and energy intake were low in these women. The nutritional supplement did not alter ratings of hunger, fullness or prospective consumption or subsequent energy and macronutrient consumption whether given 90 or 30 min before the meal. There were significant independent correlations between the lack of adequate compensation of energy intake at meals and chronic undernutrition (as assessed by skinfold thickness) and energy intake during the control meal. We conclude that elderly women during the recovery phase after major fractures have low appetites and energy intakes and markedly impaired adjustment of energy intake following liquid oral nutritional supplements. The reasons for this are unknown but are related to anorexia and undernutrition. The consumption of liquid oral supplements given up to 30 min before a meal does not suppress subsequent energy intake from meals.

Abstract
BACKGROUND Malnutrition is associated with poor outcomes in older adults and those admitted to rehabilitation may be particularly at risk. Objective To assess the nutritional status and outcomes of older adults in rehabilitation. SUBJECTS AND METHODS We recruited 133 adults > or = 65 years from consecutive rehabilitation admissions. Nutritional status was assessed using the mini nutritional assessment, body mass index (BMI) and corrected arm muscle area (CAMA). Outcomes measured included length of stay, admission to higher level care, function and quality of life (QOL). RESULTS Sixty-two (47%) subjects were well nourished, 63 (47%) at risk of malnutrition and eight (6%) malnourished. Twenty-two (17%) and 27 (20%) were below the desirable reference values for BMI and CAMA respectively. Subjects at risk of malnutrition/malnourished had longer length of stay (P = 0.023) and were more likely to be admitted to higher level care (P < 0.05). These subjects also had poorer function on admission (P < 0.001) and 90 days (P = 0.002) and QOL on admission (P < 0.008) and 90 days (P = 0.001). Those with low CAMA were twice as likely to be admitted to higher level care (P < 0.05) and had poorer function at 90 days (P = 0.017). CONCLUSIONS Over half our sample was identified as at risk of malnutrition or malnourished and this was associated with poorer clinical outcomes.
