Abstract
BACKGROUND & AIMS No generalizable formulas exist that are derived from bioelectrical impedance analysis (BIA) for predicting appendicular lean mass (ALM) and fat mass (AFM) in sarcopenic older adults. Since precision of regional body composition (BC) data in multicentre trials is essential, this study aimed to: 1) develop and cross-validate soft tissue BIA equations with GE Lunar and Hologic DXA systems as their reference 2) to compare our new ALM equation to two previously published models and 3) to assess the agreement between BIA- and DXA-derived soft tissue ratios as indicators of limb tissue quality. METHODS Two-hundred and ninety-one participants with functional limitations (SPPB-score 4-9; sarcopenia class I or II, measured by BIA) were recruited from 18 study centres in six European countries. BIA equations, using DXA-derived ALM and AFM as the dependent variable, and age, gender, weight, impedance index and reactance as independent variables, were developed using a stepwise multiple linear regression approach. RESULTS Cross-validation gave rise to 4 equations using the whole sample: ALMLUNAR (kg) = 1.821 + (0.168*height2/resistance) + (0.132*weight) + (0.017*reactance) - (1.931*sex) [R2 = 0.86 and SEE = 1.37 kg] AFMLUNAR (kg) = -6.553 - (0.093* height2/resistance) + (0.272*weight) + (4.295*sex) [R2 = 0.70 and SEE = 1.53 kg] ALMHOLOGIC (kg) = 4.957 + (0.196* height2/resistance) + (0.060*weight) - (2.554*sex) [R2 = 0.90 and SEE = 1.28 kg] AFMHOLOGIC (kg) = -4.716 - (0.142* height2/resistance) + (0.316*weight) + (4.453*sex) - (0.040*reactance) [R2 = 0.73 and SEE = 1.54 kg] Both previously published models significantly overestimated ALM in our sample with biases of -0.36 kg to -1.05 kg. For the ratio of ALM to AFM, a strong correlation (r = 0.82, P < 0.0001) was found between the mean estimate from BIA and the DXA models without significant difference (estimated bias of 0.02 and 95% LOA -0.62, 0.65). CONCLUSION We propose new BIA equations allowing the estimation of appendicular lean and fat mass. Our equations allow to accurately estimate the appendicular lean/fat ratio which might provide information regarding limb tissue quality, in clinical settings. Furthermore, these BIA equations can be applied to characterize sarcopenia with Hologic and Lunar reference values for BC. Previously published BIA-based models tend to overestimate ALM in sarcopenic older adults. Users of both GE Lunar and Hologic may now benefit from these equations in field research.

Abstract
OBJECTIVE To compare the ability of different frailty indexes based on a standardized comprehensive geriatric assessment (FI-CGAs) for predicting adverse outcomes. DESIGN AND SETTING Prospective cohort study. Geriatric wards of a general hospital. PARTICIPANTS 307 hospitalized patients ≥ 65 years. MEASUREMENTS The FI-CGA-10D (potential health deficits in ten functional domains), the FI-CGA-10D+CM (aforementioned potential health deficits and co-morbidity burden) and the FI-CGA-MIHD (multiple, individual potential health deficits, including functional deficits, co-morbid diseases, amongst others) were assessed at baseline during the patients` hospital stay. The FI-CGAs were analyzed as categorical (according to a FI-CGA score < and ≥ 0.25) and continuous variables. Patients were followed up over 6 months. RESULTS The FI-CGA-10D, FI-CGA-10+CM and the FI-CGA-MIHD predicted 6-month mortality when expressed as categorical (area under the receiver operating characteristic curve (AUC): AUC = 0.611, AUC = 0.637, AUC = 0.616, all p < 0.050, respectively) or continuous variables (AUC = 0.769, AUC = 0.837, AUC = 0.834, all p < 0.001, respectively). AUC comparisons showed that all three FI-CGAs exhibited a comparable ability to predict 6-month mortality when the FI-CGAs were expressed as categorical variables (all p > 0.200) and the FI-CGA-10D+CM and the FI-CGA-MIHD showed a better ability to predict 6-month mortality than the FI-CGA-10D, when the FI-CGAs were expressed as continuous variables (p < 0.001 and p = 0.007, respectively). None of the FI-CGAs predicted any of the other outcomes, i.e., unplanned re-admission to hospital and a fall during follow-up, irrespective of whether the FI-CGAs were expressed as categorical or continuous variables (all p ≥ 0.050). CONCLUSIONS The more complex FI-CGAs, i.e., the FI-CGA-10D+CM and the FI-CGA-MIHD, revealed better ability to predict 6 month mortality than the more simple FI-CGA, i.e., the FI-CGA-10D.

Abstract
OBJECTIVES The aims of this study were to determine the prevalence of malnutrition in patients of a geriatric day hospital using the Mini Nutritional Assessment short form (MNA-SF) and the full MNA, to compare both tools, and to examine the relationship between nutritional and functional status. DESIGN Cross-sectional study. SETTING Geriatric day hospital. PARTICIPANTS 190 patients (72.1% female, median 80 years) aged 65 years or older. MEASUREMENTS In consecutively admitted geriatric day hospital patients nutritional status was assessed by MNA-SF and full MNA, and agreement between both tools calculated by Cohen´s kappa. Basic activities of daily living (ADL), instrumental activities of daily living (IADL) and short physical performance battery (SPPB) were determined and related to MNA categories (Chi2-test, Mann-Whitney-U-test). RESULTS 36.3 % and 44.7% of the patients were at risk of malnutrition, 8.9 % and 5.8 % were malnourished according to MNA-SF and full MNA, respectively. Agreement between both MNA forms was moderate (κ=0.531). No significant associations between MNA-SF and ADL, IADL and SPPB, and between full MNA and SPPB were observed. According to full MNA, the proportion of patients with limitations in ADL and IADL significantly increased with declining nutritional status (ADL: 2.1 vs. 8.2 vs. 18.2 %, p=0.044; IADL: 25.5 vs. 47.1 vs. 54.5 %, p=0.005) with a simultaneous decrease of the proportion of patients without limitations. Well-nourished patients reached significantly higher ADL scores than patients at risk of malnutrition (95 (90-100) vs. 95 (85-100), p=0.005) and significantly higher IADL scores than patients at risk or malnourished (8 (6-8) vs. 7 (5-8) vs. 6 (4-8), p=0.004). CONCLUSION The high prevalence of risk of malnutrition and the observed association between functional status and nutritional status according to full MNA call for routine nutritional screening using this tool in geriatric day hospital patients.

Abstract
OBJECTIVES There are few data regarding the accuracy of short frailty tools as predictors of mortality and other clinical outcomes of older patients admitted to a geriatric ward. We therefore analyzed the accuracy of Rockwood et al's Clinical Frailty Scale and an easy and quick to perform operationalization of Fried et al's frailty phenotype, as predictors of mortality and other clinical outcomes in our cohort of patients. DESIGN Prospective analysis with a follow-up period of 6 months. SETTING AND PARTICIPANTS 307 patients who were 65 years of age or older were included in the study. The patients were assessed in terms of the two frailty measures during their stay in a geriatric ward. RESULTS The Clinical Frailty Scale and the frailty phenotype were both suitable for differentiating between patients who died due to any cause from those who survived during follow-up (primary outcome) (area under the ROC curves (AUC) values 0.867 (95% CI 0.807-0.926), p<0.001 and 0.754 (95% CI 0.688-0.821), p<0.001, respectively). Regarding the secondary outcomes: 1. unplanned admission to hospital and 2. a fall during follow-up, the Clinical Frailty Scale discriminated or tended to discriminate between patients to whom these criteria applied and those to whom they did not (AUC=0.569 (95% CI 0.502-0.636), p=0.046 and AUC=0.574 (95% CI 0.501-0.647), p=0.071, respectively). The frailty phenotype did not show such a differentiation when applied to secondary outcomes (AUC=0.500 (95% CI 0.432-0.568), p=0.994 and AUC=0.518 (95% CI 0.439-0.598), p=0.658, respectively). CONCLUSIONS Both short frailty instruments are suitable predictors of mortality in older patients who were admitted to a geriatric ward. The Clinical Frailty Scale, but not the frailty phenotype, predicted at least some of the secondary outcomes, i.e., the outcome unplanned admission to hospital during follow-up.

Abstract
Background Although sarcopenia represents a challenging burden for health care systems around the world, its prevalence in the elderly population varies widely. The primary aim of the study was to determine the prevalence of sarcopenia in community-dwelling (CD) German women aged 70 years and older; the secondary aim was to assess the effect of osteoarthritis (OA) on sarcopenia prevalence in this cohort. Methods A total of 689 Caucasian females 18–35 years old and 1,325 CD females 70 years+ living in Northern Bavaria, Germany, were assessed during the initial phase of the FORMoSA research project. Anthropometry, total and regional muscle mass, were assessed by segmental multifrequency Bioelectrical Impedance Analysis. Further 10 m walking speed and handgrip strength were evaluated to apply the European Working Group on Sarcopenia in Older People definition of sarcopenia. Covariates were determined by questionnaires and interviews. Results Applying the algorithm of the European Working Group on Sarcopenia in Older People of two standard deviations below the mean value for appendicular skeletal muscle mass of a reference cohort of the young cohort (5.66 kg/m2), low gait speed (≤0.8 m/s), and low grip strength (<20 kg), the prevalence of sarcopenia in CD German females 70 years and older was 4.5% (70–79 years: 2.8% vs ≥80 years: 9.9%; P<0.001). Participants with OA at the hip and lower limbs (n=252) exhibited significantly higher rates of sarcopenia (OA: 9.1 vs non-OA: 3.5%). Of importance, anthropometric, demographic, health, and lifestyle parameters (except exercise participation) of our cohorts corresponded with Bavarian or German data for CD women 70 years+. Conclusion The prevalence of sarcopenia in CD German females 70 years+ is relatively low. However, participants with OA at the hip or lower limbs were at increased risk for sarcopenia.

Abstract
BACKGROUND The prevalence of delirium in hospitalized patients is high, but delirium is frequently not identified by treating physicians in emergency departments (EDs). Although the number of elderly patients admitted to EDs is increasing, no data on prevalence, identification and outcome of delirious elderly patients in German EDs exist. OBJECTIVES To evaluate the prevalence and identification of delirium in elderly patients in a German ED and to identify characteristics of delirium in elderly ED patients. METHODS Evaluation of data from a prospective single-center observational study. The study was conducted in the interdisciplinary ED of an urban university-affiliated hospital receiving approximately 80,000 visits per year. The shortened Confusion Assessment Method (CAM) was used to screen 133 consecutive ED patients, aged 75 years and older, for delirium. Comorbid conditions were ascertained by patient interview and review of medical records. Data concerning patient mortality and current living status were collected 28 days after the ED visit in a structured telephone interview. RESULTS A positive CAM result was recorded in 14.3 % of cases; 68.4 % of these CAM-positive patients were not identified as being delirious by the ED physician. The 28-day mortality was higher among patients with delirium. Dependency on external help, polypharmacy, pre-existing cognitive or mobility impairments and the presence of any care level were strongly associated with delirium. CONCLUSION Elderly patients with known risk factors should be routinely assessed for delirium in the ED with a standardized assessment tool such as the CAM.

Abstract
BACKGROUND Sarcopenia is linked to functional impairments, loss of independence, and mortality. In the past few years, obesity has been established as being a risk factor for a decline in muscle mass and function. There are several molecular pathological mechanisms, which have been under discussion that might explain this relationship. However, most studies were conducted using male animals and for a short period of time. METHODS In this study, the gender-specific effect of long-term, high-fat content feeding in Sprague-Dawley rats was examined. Development of the quadriceps muscle of the animals was monitored in vivo using magnetic resonance. The results of these measurements and of the biochemical analysis of the aged muscle were compared. RESULTS Surprisingly, only male but not female rats showed a decline in muscle cross-sectional area at 16 months of age as a result of a chronic oversupply of dietary fats. This loss of muscle mass could not be explained by either de-regulation of the anabolic Akt pathway or by up-regulation of the main ubiquitin ligases of muscle, MAFbx and MuRF-1. However, fusion of satellite cells to myotubes was induced by the high-fat diet in male rats, possibly as a result of an increased need for compensatory regeneration processes. Caspase-3-dependent apoptosis induction, irrespective of diet, seems to be the major determinant of muscle decline during ageing in male but not female rats. CONCLUSION Taken together, activation of the apoptosis-inducing Caspase-3 seems to be the most important trigger for the age-related muscle loss. Male rats were more prone to the decline of muscle during ageing than female animals, which was further enforced by a long-term, high fat diet.

Abstract
BACKGROUND One of the main causes of acute kidney injury (AKI) in patients treated on an intensive care unit (ICU) is sepsis. The identification of new biomarkers indicating the early development and future course of AKI are of utmost medical interest. The C-terminal agrin fragment (CAF) is measurable in blood serum and might reflect kidney function. Therefore, this study evaluates CAF in patients presenting to an internal ICU with severe sepsis or septic shock. Serum levels of CAF are correlated with biomarkers of kidney function, markers of systemic inflammation, and the presence of AKI and renal replacement therapy (RRT). METHODS 61 patients suffering from severe sepsis or septic shock were included during the first 24 hours of ICU treatment and blood samples for biomarker measurements, i.e., CAF, creatinine, cystatin C, procalcitonin (PCT), interleukin 6, C reactive protein (CRP), and white blood cells (WBC) were collected on the first day of intensive care treatment. The number of RRT days and the incidence of AKI were documented. RESULTS 13% of the patients (8/61) suffered from SIRS/sepsis, 20% (12/61) from severe sepsis, and 67% (41/61) from septic shock. Serum levels of CAF significantly correlated with creatinine (r = 0.623, p < 0.001) and cystatin C (r = 0.578, p < 0.001). Multiple linear regression analyses adjusting CAF for inflammatory parameters (i.e., WBC, CRP, interleukin 6, PCT), age, and gender showed a strong correlation between CAF and creatinine (r = 0.643, p < 0.001). Serum levels of CAF were significantly associated with the need of RRT (area under the curve (AUC) = 0.772, 95% CI: 0.641-0.903, p = 0.002) and the incidence of AKI (AUC = 0.721, 95% CI: 591-0.850, p = 0.004) as indicated by ROC analysis. CONCLUSIONS In patients suffering from severe sepsis and septic shock, serum levels of CAF were significantly associated with kidney function and RRT and were not influenced by severe septic conditions.

Abstract
BACKGROUND Geriatric rehabilitation might be the only way for the very old to maintain their participation in social life, since in many cases self care, everyday skills and basic activities of daily living can only be recovered by an integrative treatment approach using a multiprofessional team setting. At the same time limited financial resources in health care have to be considered to make appropriate allocation decisions in geriatric rehabilitation. PURPOSE The goal of this work was to determine whether chronological age is a limiting factor for functional outcome in geriatric rehabilitation. MATERIALS AND METHODS Data from the state of Baden-Württemberg (KODAS data set) from the years 2005-2011 for nonagenarians and data for centenarians from the Geriatrics in Bavaria database (GiB-DAT) project from the years 2003-2011 were compared to the data of the younger seniors undergoing geriatric rehabilitation. For the KODAS data collection, 31 geriatric rehabilitation clinics in Baden-Württemberg were involved. The GiB-DAT project included 59 geriatric rehabilitation clinics in Bavaria. Both databases compare the results of the geriatric assessment at the beginning and at the end of geriatric rehabilitation. RESULTS The analyzed data are presented with regard to the functional outcome in the very elderly and are discussed with respect to policy implications.

Abstract
OBJECTIVES Administration of oral nutritional supplements (ONS) is an effective strategy to treat and avoid malnutrition, a persisting issue in nursing homes. However, little is known about compliance in the NH population. This study aimed to analyse the effects of compliance of NH residents with a low-volume, nutrient- and energy-dense ONS on nutritional status and to identify residents' characteristics associated with compliance. DESIGN AND SETTING Randomized, controlled trial in nursing homes. PARTICIPANTS AND INTERVENTION 87 nursing home residents (87 ± 6y, 91% female) with malnutrition or at risk of malnutrition were randomly allocated to an intervention group (IG) receiving 2 x 125 ml ONS (2.4 kcal/ml)/d for 12 weeks, or the control group (CG) with usual care. MEASUREMENTS ONS intake was recorded daily and compliance calculated. Low and high compliance were defined as ≤ 30% and ≥ 80% of provided ONS actually consumed, respectively. Body weight (BW), BMI, upper-arm (UAC) and calf-circumference (CC) and MNA-SF were assessed at baseline and after 12 weeks. Associations between compliance and changes of nutritional parameters and residents' characteristics were analysed. RESULTS Compliance was high in 35.7% and low in 28.6% of the IG (n=42). BW change was significantly higher in subjects with high compliance (median +3.0 (interquartile range +2.1;+3.8) kg, n=15) than in those with low compliance (-0.2 (-2.2;+1.6) kg, n=12) and CG (-0.1 (-1.2; +0.6) kg, n=35; p<0.001), and significantly correlated with compliance in IG (r=0.691; p<0.001). Significant differences and correlations were also identified for BMI, UAC and MNA-SF. High compliance was more often observed in residents with malnutrition (66.7 vs. 27.3%) and chewing difficulties (77.8 vs. 24.2%) than in those without these conditions. Low compliance was more prevalent in residents who were immobile (45.0 vs. 13.6%), depressed (33.3 vs. 6.7%) or had gastrointestinal complaints (50.0 vs. 17.9%) (all p<0.05). CONCLUSIONS A high compliance of nursing home residents with a low volume, nutrient- and energy dense ONS was related to a significantly improved nutritional status in comparison to low compliance and therefore enhanced the effectiveness of ONS. A higher compliance may be achieved by consideration of different residents' characteristics.

Abstract
An age-dependent decline in skeletal muscle mass, strength, and endurance during the aging process is a physiological development, but several factors may exacerbate this process, leading to the threatening state of sarcopenia, frailty, and eventually higher mortality rates. Obesity appears to be such a promoting factor and has been linked in several studies to sarcopenia. The reason for this causal association remains poorly understood. Notwithstanding the fact that a higher body mass might simply lead to diminished physical activity and therefore contribute to a decline in skeletal muscle, several molecular mechanisms have been hypothesized. There could be an obesity derived intracellular lipotoxicity (i.e., elevated intramuscular levels of lipids and their derivatives), which induces apoptosis by means of an elevated oxidative stress. Paracrine mechanisms and inflammatory cytokines, such as CRP and IL-6 could be confounders of the actual underlying pathological mechanism. Due to a cross-talk of the hypothalamo-pituitary axis with nutritional status, obese subjects are more in a catabolic state of metabolism, with a higher susceptibility to muscle wasting under energy restriction. Obesity induces insulin resistance in the skeletal muscle, which consequently leads to perturbed metabolism, and misrouted signaling in the muscle cells. In obesity, muscle progenitor cells could differentiate to an adipocyte-like phenotype as a result of paracrine signals from (adipo)cytokines leading to a reduced muscular renewal capacity. The present review outlines current knowledge concerning possible pathways, which might be involved in the molecular pathogenesis of sarcopenic obesity.

Abstract
Der Begriff Sarkopenie steht für den alters-bedingten Verlust von Muskelmasse und ist eng mit dem im Alter so häufigen „Frailty-Syndrom“ assoziiert. Die Suche nach einer Sarkopenie – die Kombination einer reduzierten Muskelmasse und -funktion oder -kraft – gehört heute zum Basisarmentarium der Diagnostik in der Geriatrie. Pathophysiologisch sind wie immer bei geriatrischen Syndromen multiple Faktoren involviert, wobei ein niederschwelliger Entzündungszustand sicher eine prädominante Rolle spielt. Eine Differenzierung zur Kachexie ist wichtig, als Letztere nur sehr schwer auf ernährungs-therapeutische Interventionen anspricht. Viele Fragen bleiben sowohl zur Pathogenese wie auch zur Diagnostik und Therapie noch offen, vorab die Bedeutung der sarkopenischen Obesitas, die quantitativ bei älteren Menschen rasch zunimmt.

Abstract
OBJECTIVES The aim of this study was to investigate the relationship between nutritional and functional status in acute geriatric patients including mobility and considering health status. DESIGN Cross-sectional study. SETTING Hospital. PARTICIPANTS 205 geriatric patients (median age 82.0 (IQR: 80-86) years, 69.3% women). MEASUREMENTS Nutritional status was determined by Mini Nutritional Assessment (MNA) and patients were categorized as well-nourished (≥ 24 points), at risk of malnutrition (17-23.5 points) or as malnourished (< 17 points). Functional status was determined by Barthel Index (BI) and Timed 'Up and Go' Test (TUG) and related to MNA categories. Using binary multiple logistic regression the impact of nutritional status on functional status was examined, adjusted for health status. RESULTS 60.3% of the patients were at risk of malnutrition and 29.8% were malnourished. Ability to perform basic activities of daily living (ADL) decreased with declining nutritional status. The proportion of patients unable to perform the TUG increased with worsening of nutritional status (45.0% vs. 50.4% vs. 77.0%, p<0.01). After adjusting for age, gender, number of diagnoses, disease severity and cognitive function, a higher MNA score significantly lowered the risk of being dependent in ADL (OR 0.85, 95 % CI 0.77-0.94) and inability to perform the TUG (OR 0.90, 95 % CI 0.82-0.99). CONCLUSION Nutritional status according to MNA was related to ADL as well as to mobility in acute geriatric patients. This association remained after adjusting for health status.

Abstract
OBJECTIVE we examined the diagnostic accuracy of different methods of body temperature measurement to diagnose infection in geriatric patients presenting to the emergency department (ED). METHODS this observational study was done in consecutive patients ≥75 years old presenting to the ED. Body temperature was determined by tympanal thermometry, temporal artery thermometry and rectal temperature measurement. Adjudicated final diagnosis of infection was done by two experts including patient history, clinical and laboratory findings as well as radiographic studies. RESULTS a total of 427 patients were included in the data analysis (age: 82.7 ± 5.1 years). Infection was present in 105 patients (24.6%). Respiratory rate, heart rate and body temperature were significantly higher in patients with infection, blood pressure was lower (P < 0.01). Body temperature measured by tympanal and temporal artery thermometry was correlated with rectal thermometry. Body temperature was significantly higher in patients with infection compared with those without infection independent of the method of body temperature measurement (P < 0.001). The diagnostic accuracy for infection quantified by the area under curve (AUC) was comparable among rectal [AUC: 0.72 (95% CI: 0.65-0.80)] and tympanal thermometry [AUC: 0.73 (95% CI: 0.66-0.81)], but significantly lower in temporal artery thermometry [AUC: 0.65 (95% CI: 0.57-0.73; P < 0.001)]. Compared with rectal measurement tympanal thermometry showed a higher bias than temporal artery thermometry (0.54 versus 0.03°C), while its limits of agreement were more narrow (-0.14 to 1.21°C versus -0.94-1.01°C). CONCLUSION diagnostic accuracy for the identification of infection was comparable among tympanal and rectal thermometry and lower for temporal artery thermometry. Different cut-off points should be used to identify infection using tympanal (37.3°C) or rectal (37.9°C) thermometry. In general, temperature measurement is an insensitive method to identify geriatric patients with infection. Registration number clinicaltrials.com: KSMC-tempger-1.

Abstract
Background To preserve muscle mass and therefore limit the risk of disability in older adults protein intake is seen as important factor. Besides the amount of protein, its distribution over the day is thought to affect protein anabolism. This cross-sectional study investigates the association between the amount and distribution of protein intake and frailty in older adults. Methods In 194 community-dwelling seniors (≥75 years) amount of protein intake and its distribution over the day (morning, noon, evening) were assessed using a food frequency questionnaire. Unevenness of protein distribution was calculated as coefficient of variation (CV). Frailty was defined as the presence of at least three, pre-frailty as the presence of one or two of the following criteria: weight loss, exhaustion, low physical activity, low handgrip strength and slow walking speed. Results 15.4% of the participants were frail, 40.5% were pre-frail. Median (min.-max.) daily protein intake was 77.5 (38.5–131.5) g, 1.07 (0.58–2.27) g/kg body weight (BW) and 15.9 (11.2–21.8) % of energy intake without significant differences between the frailty groups. The risk of frailty did not differ significantly between participants in the higher compared to the lowest quartile of protein intake. Frail participants consumed significantly less protein in the morning (11.9 vs. 14.9 vs. 17.4%, p = 0,007), but more at noon (61.4 vs. 60.8 vs. 55.3%, p = 0.024) than pre-frail and non-frail. The median (min.-max.) CV of protein distribution was highest in frail (0.76 (0.18–1.33)) compared to pre-frail (0.74 (0.07–1.29)) and non-frail (0.68 (0.15–1.24)) subjects (p = 0.024). Conclusions In this sample of healthy older persons, amount of protein intake was not associated with frailty, but distribution of protein intake was significantly different between frail, pre-frail and non-frail participants. More clinical studies are needed to further clarify the relation between protein intake and frailty.

Abstract
BACKGROUND Impaired olfaction is considered to be a risk factor for malnutrition in older adults; however, there is little research on this association. The aim of this study was to investigate whether olfactory deficits are associated with an impaired nutritional status in older patients. METHODS Study participants were recruited from a geriatric day hospital. Nutritional status was assessed with body mass index and Mini-Nutritional Assessment. Olfactory function was evaluated with the Sniffin' Sticks test (SST) and subjectively rated by the patient. Self-caring capacity was rated with the Barthel Index and cognitive status with the Mini-Mental State Examination. RESULTS One hundred ninety-one patients, 71.7% female, were included with a mean age of 79.6 ± 6.3 years. Prevalence of hyposmia was 39.3%, and 31.9% of patients were functionally anosmic. Malnourished patients did not have a significantly lower Sniffin' Sticks test score than patients at nutritional risk or malnourished patients. In linear regression analysis, nutritional status was only influenced by Barthel Index, age, and number of drugs but not by olfactory function. CONCLUSION In this sample, olfactory function was not associated with nutritional status.

Abstract
BACKGROUND The European Society for Clinical Nutrition and Metabolism (ESPEN) has recommended the Mini Nutritional Assessment (MNA®), the Nutritional Risk Screening 2002 (NRS), and the Malnutrition Universal Screening Tool (MUST) for nutritional screening in various settings and age groups. While in recent years all three tools have been applied to nursing home residents, there is still no consensus on the most appropriate screening tool in this specific setting. AIM The present study aims at comparing the MNA, the NRS, and the MUST with regard to applicability, categorization of nutritional status, and predictive value in the nursing home setting. METHOD MNA, NRS, and MUST were performed on 200 residents from two municipal nursing homes in Nuremberg, Germany. Follow-up data on infection, hospitalization, and mortality were collected after six and again after twelve months. RESULTS Among 200 residents (mean age 85.5 ± 7.8 years) the MNA could be completed in 188 (94.0%) and the NRS and MUST in 198 (99.0%) residents. The prevalence of 'malnutrition' according to the MNA was 15.4%. The prevalence of 'risk of malnutrition' (NRS) and 'high risk of malnutrition' (MUST), respectively, was 8.6% for both tools. The individual categorization of nutritional status showed poor agreement between NRS and MUST on the one hand and MNA on the other. For all tools a significant association between nutritional status and mortality was demonstrated during follow-up as classification in 'malnourished', respectively 'high risk of malnutrition' or 'nutritional risk', was significantly associated with increased hazard ratios. However, the MNA showed the best predictive value for survival among well-nourished residents. CONCLUSION The evaluation of nutritional status in nursing home residents by MNA, NRS, and MUST shows significant differences. This observation may be of clinical relevance as nutritional intervention is usually based on screening results. As the items of the MNA reflect particularities of the nursing home population, this tool currently appears to be the most suitable one in this setting.
