Withrow DR, Oke J, Friedemann Smith C, Hobbs R, Nicholson BD. Serious disease risk among patients with unexpected weight loss: a matched cohort of over 70 000 primary care presentations. J Cachexia Sarcopenia Muscle 2022; 13:2661-2668. [PMID: 36056750 PMCID: PMC9745555 DOI: 10.1002/jcsm.13056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 04/06/2022] [Accepted: 07/05/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Unexpected weight loss (UWL) in patients consulting in primary care presents dilemmas for management because of the broad differential diagnoses associated with UWL. Research on the risks of serious disease among patients with UWL to date has largely taken place in secondary care, limiting generalizability to primary care patients. In this study, we use a large matched cohort study to estimate the risks of 12 serious diseases among patients presenting to primary care with UWL where this was recorded, stratified by age and sex, in order to inform a rational clinical approach to patients presenting with UWL. METHODS This was a retrospective matched cohort study using electronic health records (EHRs) from the UK Clinical Practice Research Datalink (CPRD). Each patient with UWL (ascertained from EHR coding) was matched to five patients without UWL and followed until the earliest of a diagnosis of the serious disease, date of death, exit from the CPRD database, or end of the study. Observed absolute risks of the 12 serious diseases were estimated as probabilities, and hazard ratios (HRs) were estimated with Cox proportional hazards models. RESULTS Between 2000 and 2012, 70 193 patients in CPRD had at least one record of UWL and were matched with 295 579 patients without UWL. Patients with UWL had significantly higher risk of nearly all serious diseases examined compared with patients without. HRs ranged from 1.43 for congestive heart failure [95% confidence interval (CI): 1.27-1.62] to 9.70 for malabsorption (95% CI: 6.81-13.82). The absolute risks of any given serious disease were relatively low (<6% after 1 year). The magnitude and rank order of absolute risks varied by age and sex. Depression was the most common diagnosis among women aged <80 with UWL (3.74% of women aged <60 and 2.46% of women aged 60-79), whereas diabetes was the most common in men <60 with UWL (2.96%) and cancer was the most common in men aged 60 and over with UWL (3.79% of men aged 60-70 and 5.28% of men aged ≥80). CONCLUSIONS This analysis provides new evidence to patients and clinicians about the risks of serious disease among patients presenting with UWL in primary care. Depending on age and sex, the results suggest that workup for UWL should include screening for diabetes, thyroid dysfunction, depression, and dementia. If performed in a timely manner, this workup could be used to triage patients eligible for cancer pathway referral.

Factors Associated with Potentially Inappropriate Transfer to the Emergency Department among Nursing Home Residents. J Am Med Dir Assoc 2021; 22:2579-2586.e7. [PMID: 33964225 DOI: 10.1016/j.jamda.2021.04.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 04/01/2021] [Accepted: 04/01/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVES To determine the factors associated with the potentially inappropriate transfer of nursing home (NH) residents to emergency departments (EDs) and to compare hospitalization costs before and after transfer of individuals addressed inappropriately vs those addressed appropriately. DESIGN Multicenter, observational, case-control study. SETTING AND PARTICIPANTS 17 hospitals in France, 1037 NH residents. MEASURES All NH residents transferred to the 17 public hospitals' EDs in southern France were systematically included for 1 week per season. An expert panel composed of family physicians, emergency physicians, geriatricians, and pharmacists defined whether the transfer was potentially inappropriate or appropriate. Residents' and NHs' characteristics and contextual factors were entered into a mixed logistic regression to determine factors associated independently with potentially inappropriate transfers. Hospital costs were collected in the national health insurance claims database for the 6 months before and after the transfer. RESULTS A total of 1037 NH residents (mean age 87.2 ± 7.1, 68% female) were transferred to the ED; 220 (21%) transfers were considered potentially inappropriate. After adjustment, anorexia [odds ratio (OR) 2.41, 95% confidence interval (CI) 1.57-3.71], high level of disability (OR 0.90, 95% CI 0.81-0.99), and inability to receive prompt medical advice (OR 1.67, 95% CI 1.20-2.32) were significantly associated with increased likelihood of potentially inappropriate transfers. The existence of an Alzheimer's disease special care unit in the NH (OR 0.66, 95% CI 0.48-0.92), NH staff trained on advance directives (OR 0.61, 95% CI 0.41-0.89), and calling the SAMU (mobile emergency medical unit) (OR 0.47, 95% CI 0.34-0.66) were significantly associated with a lower probability of potentially inappropriate transfer. Although the 6-month hospitalization costs prior to transfer were higher among potentially inappropriate transfers compared with appropriate transfers (€6694 and €4894, respectively), transfer appropriateness was not significantly associated with hospital costs. CONCLUSIONS AND IMPLICATIONS Transfers from NHs to hospital EDs were frequently appropriate. Transfer appropriateness was conditioned by NH staff training, access to specialists' medical advice, and calling the SAMU before making transfer decisions.

Nutrients 2020; 12:E3383. [PMID: 33158071 PMCID: PMC7694182 DOI: 10.3390/nu12113383] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 10/29/2020] [Accepted: 10/31/2020] [Indexed: 01/17/2023] Open
Abstract
The aim of this critical review was to clarify recommended fluid intake for older people. A literature search of published articles and guidelines on fluid intake recommendations until April 2020 was carried out using PUBMED, Scopus, Cochrane, and Google Scholar. In this review, we focused on people over 65 years old at different care levels. The results show that the mean fluid intake ranges between 311 and 2390 mL/day. However, it is difficult to know whether this corresponds to the real pattern of fluid intake, due to the variability of data collection methods. With respect to the recommendations, most international organizations do not take into consideration the physiology of ageing or the health problems associated with an older population. In conclusions, we recommend to follow the guideline of the European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Food Safety Authority (EFSA). ESPEN is the only guideline which takes into account age. It is also based on EFSA recommendations. This authority takes into consideration all fluids consumed (ranging from food to fluids). If it is known that around 20% of all fluids consumed come from food, the result would effectively be that the EFSA recommends the same as the ESPEN guidelines: 1.6 L/day for females and 2.0 L/day for males. The findings could help raise the awareness of professionals in the sector with respect to the required fluid intake of the elderly and, in this way, contribute to avoiding the consequences of dehydration.

Body Weight Variation Patterns as Predictors of Cognitive Decline over a 5 Year Follow-Up among Community-Dwelling Elderly (MAPT Study). Nutrients 2019; 11:nu11061371. [PMID: 31216732 PMCID: PMC6627683 DOI: 10.3390/nu11061371] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Revised: 06/06/2019] [Accepted: 06/07/2019] [Indexed: 02/07/2023] Open
Abstract
This study aimed to analyze associations between weight variation patterns and changes in cognitive function and hippocampal volume among non-demented, community-dwelling elderly. Sample was formed of 1394 adults >70 years (63.9% female), all volunteers from the Multidomain Alzheimer Preventive Trial (MAPT). Weight loss was defined as ≥5% of body weight decrease in the first year of follow-up; weight gain as ≥5% of weight increase; and stability if <5% weight variation. Cognition was examined by a Z-score combining four tests. Measures were assessed at baseline, 6, 12, 24, 36, 48, and 60 months of follow-up. Hippocampal volume was evaluated with magnetic resonance imaging in 349 subjects in the first year and at 36 months. Mixed models were performed. From the 1394 participants, 5.5% (n = 76) presented weight loss, and 9.0% (n = 125) presented weight gain. Cognitive Z-score decreased among all groups after 5 years, but decline was more pronounced among those who presented weight loss (adjusted between-group mean difference vs. stable: -0.24, 95%CI: -0.41 to -0.07; p = 0.006). After 3 years, hippocampal atrophy was observed among all groups, but no between-group differences were found. In conclusion, weight loss ≥5% in the first year predicted higher cognitive decline over a 5 year follow-up among community-dwelling elderly, independently of body mass index.

Abstract
BACKGROUND Weight loss is a non-specific cancer symptom for which there are no clinical guidelines about investigation in primary care. AIM To summarise the available evidence on weight loss as a clinical feature of cancer in patients presenting to primary care. DESIGN AND SETTING A diagnostic test accuracy review and meta-analysis. METHOD Studies reporting 2 × 2 diagnostic accuracy data for weight loss (index test) in adults presenting to primary care and a subsequent diagnosis of cancer (reference standard) were included. QUADAS-2 was used to assess study quality. Sensitivity, specificity, positive likelihood ratios, and positive predictive values were calculated, and a bivariate meta-analysis performed. RESULTS A total of 25 studies were included, with 23 (92%) using primary care records. Of these, 20 (80%) defined weight loss as a physician's coding of the symptom; the remainder collected data directly. One defined unexplained weight loss using objective measurements. Positive associations between weight loss and cancer were found for 10 cancer sites: prostate, colorectal, lung, gastro-oesophageal, pancreatic, non-Hodgkin's lymphoma, ovarian, myeloma, renal tract, and biliary tree. Sensitivity ranged from 2% to 47%, and specificity from 92% to 99%, across cancer sites. The positive predictive value for cancer in male and female patients with weight loss for all age groups ≥60 years exceeded the 3% risk threshold that current UK guidance proposes for further investigation. CONCLUSION A primary care clinician's decision to code for weight loss is highly predictive of cancer. For such patients, urgent referral pathways are justified to investigate for cancer across multiple sites.

Abstract
OBJECTIVES The purposes of this study were to evaluate the correlation between sarcopenia and water intake and investigate lack of daily water intake in the presence of sarcopenia in an elderly population. METHODS Data from 3656 participants (1582 men and 2074 women) were analyzed using the Korea National Health and Nutrition Examination Survey. Sarcopenia was defined in accordance with the criteria of the Asia Working Group for Sarcopenia. Water intake was assessed using the dietary water adequacy ratio and was calculated by dividing the daily water intake from fluid by the recommended daily amount of 1000 mL in men and 900 mL in women. RESULTS Water intake from food (g/d and cup/d) and dietary water adequacy ratio (mL) were significantly lower in the sarcopenia group (757.8 g, 890.1 g, and 0.74 mL in men; 511.9 g, 757.8 g, and 0.70 mL in women, respectively) than in the non-sarcopenia group (878.4 g, 1015.1 g, and 0.81 mL in men; 581.3 g, 790.5 g, 0.74 mL in women, respectively). In elderly men, the odds ratio of sarcopenia in the lowest quartile increased to 1.47 (range, 1.13-1.91) in Model 2 compared with that in the highest quartile. In elderly women, the odds ratio of sarcopenia in the lowest quartile increased to 1.50 (range, 1.08-2.08) in Model 2 compared with that in the highest quartile. CONCLUSIONS The prevalence of sarcopenia in the elderly population was related to inadequate dietary water intake after adjusting for covariates. Adequate water intake in the elderly should be recommended to prevent dehydration-related complications, including sarcopenia.

Abstract
Aging is associated with visceral adiposity, metabolic disorders, and chronic low-grade inflammation. 17α-estradiol (17α-E2), a naturally occurring enantiomer of 17β-estradiol (17β-E2), extends life span in male mice through unresolved mechanisms. We tested whether 17α-E2 could alleviate age-related metabolic dysfunction and inflammation. 17α-E2 reduced body mass, visceral adiposity, and ectopic lipid deposition without decreasing lean mass. These declines were associated with reductions in energy intake due to the activation of hypothalamic anorexigenic pathways and direct effects of 17α-E2 on nutrient-sensing pathways in visceral adipose tissue. 17α-E2 did not alter energy expenditure or excretion. Fasting glucose, insulin, and glycosylated hemoglobin were also reduced by 17α-E2, and hyperinsulinemic-euglycemic clamps revealed improvements in peripheral glucose disposal and hepatic glucose production. Inflammatory mediators in visceral adipose tissue and the circulation were reduced by 17α-E2. 17α-E2 increased AMPKα and reduced mTOR complex 1 activity in visceral adipose tissue but not in liver or quadriceps muscle, which is in contrast to the generalized systemic effects of caloric restriction. These beneficial phenotypic changes occurred in the absence of feminization or cardiac dysfunction, two commonly observed deleterious effects of exogenous estrogen administration. Thus, 17α-E2 holds potential as a novel therapeutic for alleviating age-related metabolic dysfunction through tissue-specific effects.

Abstract
BACKGROUND There is evidence that water-loss dehydration is common in older people and associated with many causes of morbidity and mortality. However, it is unclear what clinical symptoms, signs and tests may be used to identify early dehydration in older people, so that support can be mobilised to improve hydration before health and well-being are compromised. OBJECTIVES To determine the diagnostic accuracy of state (one time), minimally invasive clinical symptoms, signs and tests to be used as screening tests for detecting water-loss dehydration in older people by systematically reviewing studies that have measured a reference standard and at least one index test in people aged 65 years and over. Water-loss dehydration was defined primarily as including everyone with either impending or current water-loss dehydration (including all those with serum osmolality ≥ 295 mOsm/kg as being dehydrated). SEARCH METHODS Structured search strategies were developed for MEDLINE (OvidSP), EMBASE (OvidSP), CINAHL, LILACS, DARE and HTA databases (The Cochrane Library), and the International Clinical Trials Registry Platform (ICTRP). Reference lists of included studies and identified relevant reviews were checked. Authors of included studies were contacted for details of further studies. SELECTION CRITERIA Titles and abstracts were scanned and all potentially relevant studies obtained in full text. Inclusion of full text studies was assessed independently in duplicate, and disagreements resolved by a third author. We wrote to authors of all studies that appeared to have collected data on at least one reference standard and at least one index test, and in at least 10 people aged ≥ 65 years, even where no comparative analysis has been published, requesting original dataset so we could create 2 x 2 tables. DATA COLLECTION AND ANALYSIS Diagnostic accuracy of each test was assessed against the best available reference standard for water-loss dehydration (serum or plasma osmolality cut-off ≥ 295 mOsm/kg, serum osmolarity or weight change) within each study. For each index test study data were presented in forest plots of sensitivity and specificity. The primary target condition was water-loss dehydration (including either impending or current water-loss dehydration). Secondary target conditions were intended as current (> 300 mOsm/kg) and impending (295 to 300 mOsm/kg) water-loss dehydration, but restricted to current dehydration in the final review.We conducted bivariate random-effects meta-analyses (Stata/IC, StataCorp) for index tests where there were at least four studies and study datasets could be pooled to construct sensitivity and specificity summary estimates. We assigned the same approach for index tests with continuous outcome data for each of three pre-specified cut-off points investigated.Pre-set minimum sensitivity of a useful test was 60%, minimum specificity 75%. As pre-specifying three cut-offs for each continuous test may have led to missing a cut-off with useful sensitivity and specificity, we conducted post-hoc exploratory analyses to create receiver operating characteristic (ROC) curves where there appeared some possibility of a useful cut-off missed by the original three. These analyses enabled assessment of which tests may be worth assessing in further research. A further exploratory analysis assessed the value of combining the best two index tests where each had some individual predictive ability. MAIN RESULTS There were few published studies of the diagnostic accuracy of state (one time), minimally invasive clinical symptoms, signs or tests to be used as screening tests for detecting water-loss dehydration in older people. Therefore, to complete this review we sought, analysed and included raw datasets that included a reference standard and an index test in people aged ≥ 65 years.We included three studies with published diagnostic accuracy data and a further 21 studies provided datasets that we analysed. We assessed 67 tests (at three cut-offs for each continuous outcome) for diagnostic accuracy of water-loss dehydration (primary target condition) and of current dehydration (secondary target condition).Only three tests showed any ability to diagnose water-loss dehydration (including both impending and current water-loss dehydration) as stand-alone tests: expressing fatigue (sensitivity 0.71 (95% CI 0.29 to 0.96), specificity 0.75 (95% CI 0.63 to 0.85), in one study with 71 participants, but two additional studies had lower sensitivity); missing drinks between meals (sensitivity 1.00 (95% CI 0.59 to 1.00), specificity 0.77 (95% CI 0.64 to 0.86), in one study with 71 participants) and BIA resistance at 50 kHz (sensitivities 1.00 (95% CI 0.48 to 1.00) and 0.71 (95% CI 0.44 to 0.90) and specificities of 1.00 (95% CI 0.69 to 1.00) and 0.80 (95% CI 0.28 to 0.99) in 15 and 22 people respectively for two studies, but with sensitivities of 0.54 (95% CI 0.25 to 0.81) and 0.69 (95% CI 0.56 to 0.79) and specificities of 0.50 (95% CI 0.16 to 0.84) and 0.19 (95% CI 0.17 to 0.21) in 21 and 1947 people respectively in two other studies). In post-hoc ROC plots drinks intake, urine osmolality and axillial moisture also showed limited diagnostic accuracy. No test was consistently useful in more than one study.Combining two tests so that an individual both missed some drinks between meals and expressed fatigue was sensitive at 0.71 (95% CI 0.29 to 0.96) and specific at 0.92 (95% CI 0.83 to 0.97).There was sufficient evidence to suggest that several stand-alone tests often used to assess dehydration in older people (including fluid intake, urine specific gravity, urine colour, urine volume, heart rate, dry mouth, feeling thirsty and BIA assessment of intracellular water or extracellular water) are not useful, and should not be relied on individually as ways of assessing presence or absence of dehydration in older people.No tests were found consistently useful in diagnosing current water-loss dehydration. AUTHORS' CONCLUSIONS There is limited evidence of the diagnostic utility of any individual clinical symptom, sign or test or combination of tests to indicate water-loss dehydration in older people. Individual tests should not be used in this population to indicate dehydration; they miss a high proportion of people with dehydration, and wrongly label those who are adequately hydrated.Promising tests identified by this review need to be further assessed, as do new methods in development. Combining several tests may improve diagnostic accuracy.

Abstract
OBJECTIVE To assess the long-term effects of an intensive lifestyle intervention on physical function using a randomized post-test design in the Look AHEAD trial. METHODS Overweight and obese (BMI ≥ 25 kg m(-2)) middle-aged and older adults (aged 45-76 years at enrollment) with type 2 diabetes (n = 964) at four clinics in Look AHEAD, a trial evaluating an intensive lifestyle intervention (ILI) designed to achieve weight loss through caloric restriction and increased physical activity compared to diabetes support and education (DSE), underwent standardized assessments of performance-based physical function including an expanded short physical performance battery (SPPBexp ), 20-m and 400-m walk, and grip and knee extensor strength 8 years post-randomization, during the trial's weight maintenance phase. RESULTS Eight years post-randomization, individuals randomized to ILI had better SPPBexp scores [adjusted mean (SE) difference: 0.055 (0.022), P = 0.01] and faster 20-m and 400-m walk speeds [0.032 (0.012) m s(-1) , P = 0.01, and 0.025 (0.011) m s(-1) , P = 0.02, respectively] compared to those randomized to DSE. Achieved weight loss greatly attenuated the group differences in physical function, and the intervention effect was no longer significant. CONCLUSIONS An intensive lifestyle intervention has long-term benefits for mobility function in overweight and obese middle-aged and older individuals with type 2 diabetes.

Abstract
AIM To translate the Simplified Nutritional Appetite Questionnaire (SNAQ) into Japanese, and assess its reliability and validity in Japanese community-dwelling older adults. METHODS A total of 84 community-dwelling older adults people aged 65 years or older were included in the present study, and those with a Mini-Mental State Examination score of <24, had dementia, had digestive disease or who did not complete the examination were excluded. The SNAQ was translated into Japanese according to an internationally accepted methodology. The internal reliability of the SNAQ was evaluated by Cronbach's alpha coefficient. Test-retest reliability was evaluated using the intraclass correlation coefficient. The dimensionality of the SNAQ was evaluated by factor analysis. Concurrent validity was evaluated by measuring the Pearson's correlation coefficient between the SNAQ and Mini-Nutritional Assessment Short-Form scores, Geriatric Depression Scale scores, walking speed test, chair-stand test, hand grip strength test, or the Timed Up and Go test. RESULTS The mean score of the Japanese version of the SNAQ was 15.5, with a Cronbach's alpha coefficient of 0.545 and intraclass correlation coefficient of 0.754. Factor analysis showed a single factor with 50.0% explained variance. The SNAQ was significantly associated with the Mini-Nutritional Assessment Short-Form, Geriatric Depression Scale, walking speed test, chair-stand test and the Timed Up and Go test. Handgrip strength test did not show a significant association with the SNAQ. CONCLUSION The Japanese version of the SNAQ had sufficient reliability and validity. Furthermore, SNAQ (Japanese version) is useful for evaluating the appetite of community-dwelling older adults in Japan. Geriatr Gerontol Int 2015; 15: 1264-1269.

Abstract
BACKGROUND Obesity impairs cognition and health-related quality of life (HRQOL) in older adults; however, the appropriate treatment of obese older adults remains controversial. OBJECTIVE The objective was to determine the independent and combined effects of weight loss and exercise on cognition, mood, and HRQOL in obese older adults. DESIGN One hundred seven frail, obese older adults were randomly assigned to a control, weight-management (diet), exercise, or weight-management-plus-exercise (diet-exercise) group for 1 y. In this secondary analysis, main outcomes were Modified Mini-Mental State Examination (3MS) and total Impact of Weight on Quality of Life-Lite (IWQOL) scores. Other outcomes included Word Fluency Test, Trail Making Test Parts A and B, and Geriatric Depression Scale (GDS) scores. RESULTS Scores on the 3MS improved more in the diet (mean ± SE: 1.7 ± 0.4), exercise (2.8 ± 0.4), and diet-exercise (2.9 ± 0.4) groups than in the control group (0.1 ± 0.4) (between-group P = 0.0001-0.04); scores in the diet-exercise group improved more than in the diet group but not more than in the exercise group. Scores on the Word Fluency Test improved more in the exercise (4.1 ± 0.8) and diet-exercise (4.2 ± 0.7) groups than in the control group (-0.8 ± 0.8; both P = 0.001). For the Trail Making Test Part A, scores in the diet-exercise group (-11.8 ± 1.9) improved more than in the control group (-0.8 ± 1.9) (P = 0.001); a similar finding was observed for the Trail Making Test Part B. Scores on the IWQOL improved more in the diet (7.6 ± 1.6), exercise (10.1 ± 1.6), and diet-exercise (14.0 ± 1.4) groups than in the control group (0.3 ± 1.6) (P = 0.0001-0.03); scores in the diet-exercise group improved more than in the diet group but not more than in the exercise group. In the diet-exercise group, peak oxygen consumption and strength changes were independent predictors of 3MS changes; weight and strength changes were independent predictors of IWQOL changes. GDS scores did not change. CONCLUSIONS Weight loss and exercise each improve cognition and HRQOL, but their combination may provide benefits similar to exercise alone. These findings could inform practice guidelines with regard to optimal treatment strategies for obese older adults. This trial was registered atclinicaltrials.govas NCT00146107.

Abstract
This review defines water-loss and salt-loss dehydration. For older people serum osmolality appears the most appropriate gold standard for diagnosis of water-loss dehydration, but clear signs of early dehydration have not been developed. In older adults, lower muscle mass, reduced kidney function, physical and cognitive disabilities, blunted thirst, and polypharmacy all increase dehydration risk. Cross-sectional studies suggest a water-loss dehydration prevalence of 20-30% in this population. Water-loss dehydration is associated with higher mortality, morbidity and disability in older people, but evidence is still needed that this relationship is causal. There are a variety of ways we may be able to help older people reduce their risk of dehydration by recognising that they are not drinking enough, and being helped to drink more. Strategies to increase fluid intake in residential care homes include identifying and overcoming individual and institutional barriers to drinking, such as being worried about not reaching the toilet in time, physical inability to make or to reach drinks, and reduced social drinking and drinking pleasure. Research needs are discussed, some of which will be addressed by the FP7-funded NU-AGE (New dietary strategies addressing the specific needs of elderly population for a healthy ageing in Europe) trial.

Abstract
BACKGROUND Obesity exacerbates the age-related decline in insulin sensitivity and is associated with risk for cardiometabolic syndrome in older adults; however, the appropriate treatment for obese older adults is controversial. OBJECTIVE To determine the independent and combined effects of weight loss and exercise on cardiometabolic risk factors in obese older adults. DESIGN One-hundred and seven obese (body mass index (BMI)≥30 kg m(-2)) older (≥65 years) adults with physical frailty were randomized to control group, diet group, exercise group and diet-exercise group for 1 year. Outcomes for this study included changes in insulin sensitivity index (ISI), glucose tolerance, central obesity, adipocytokines and cardiometabolic syndrome. RESULTS Although similar increases in ISI occurred in the diet-exercise and diet groups at 6 months, the ISI improved more in the diet-exercise than in the diet group at 12 months (2.4 vs 1.2; between-group difference, 1.2; 95% confidence interval, 0.2-2.1); no changes in ISI occurred in both exercise and control groups. The diet-exercise and diet groups had similar improvements in insulin area under the curve (AUC) (-2.9 and -2.9 × 10(3) mg min dl(-1)), glucose AUC (-1.4 and -2.2 × 10(3)mg min dl(-1)), visceral fat (-787 and -561 cm(3)), tumor necrosis factor (-17.0 and -12.8 pg ml(-1)), adiponectin (5.0 and 4.0 ng ml(-1)), waist circumference (-8.2 and -8.4 cm), triglyceride (-30.7 and -24.3 g dl(-1)) and systolic/diastolic blood pressure (-15.9 and -13.1/-4.9 and -6.7 mm Hg), while no changes in these parameters occurred in both exercise and control groups. The cardiometabolic syndrome prevalence decreased by 40% in the diet-exercise and by 15% in the diet group. Body weight decreased similarly in the diet-exercise and diet groups (-8.6 and -9.7 kg) but not in the exercise and control groups. CONCLUSIONS In frail, obese older adults, lifestyle interventions associated with weight loss improve insulin sensitivity and other cardiometabolic risk factors, but continued improvement in insulin sensitivity is only achieved when exercise training is added to weight loss.

Abstract
Obesity in older adults is ubiquitous in many developed countries and is related to various negative health outcomes, making it an important public health target for intervention. However, treatment approaches for obesity in older adults remain controversial due to concerns surrounding the difficulty of behavior change with advancing age, exacerbating the age-related loss of skeletal muscle and bone, and the feasibility of long-term weight maintenance and related health consequences. This review serves to systematically examine the evidence regarding weight loss interventions with a focus on obese (body mass index 30kg/m(2) and above) older adults (aged 65years and older) and some proposed mechanisms associated with exercise and caloric restriction (lifestyle intervention). Our findings indicate that healthy weight loss in this age group can be achieved through lifestyle interventions of up to a one-year period. Most interventions reviewed reported a loss of lean body mass and bone mineral density with weight loss. Paradoxically muscle quality and physical function improved. Inflammatory molecules and metabolic markers also improved, although the independent and additive effects of exercise and weight loss on these pathways are poorly understood. Using our review inclusion criteria, only one small pilot study investigating long-term weight maintenance and associated health implications was found in the literature. Future research on lifestyle interventions for obese older adults should address the loss of bone and lean body mass, inflammatory mechanisms, and include sufficient follow-up to assess long-term weight maintenance and health outcomes.

Abstract
Although weight loss ameliorates many of the metabolic abnormalities associated with obesity, there has been reluctance to prescribe weight loss in obese, older individuals because of the fear that it will cause debilitating loss of muscle mass and impair physical function. To gain insight into the mechanisms responsible for the weight loss-induced changes in muscle mass, we measured the rate of muscle protein synthesis (by using stable isotope labeled tracer methodology) during basal, postabsorptive conditions and during mixed meal ingestion in eight obese, older adults: (i) before weight loss therapy, (ii) ~3 months after starting the weight loss intervention (i.e., during the active weight loss phase), when subjects had lost ~7% of their initial body weight, and (iii) after they had lost ~10% of their body weight and maintained this new body weight for ~6 months (~12 months after starting the weight loss intervention). The basal muscle protein fractional synthesis rate (FSR) was not affected by weight loss. Mixed meal ingestion stimulated the rate of muscle protein synthesis, and the anabolic response (i.e., increase in the protein synthesis rate above basal values) was greater (P < 0.05) during negative energy balance and active weight loss at 3 months (0.033 ± 0.012%·per hour, mean ± s.e.m.) than during weight maintenance before and at 12 months of weight loss therapy (0.003 ± 0.003 and 0.008 ± 0.012%·per hour, respectively). We conclude that during dietary calorie restriction and weight loss in older adults, the rate of muscle protein synthesis is not impaired. Thus, the loss of muscle mass must be mediated predominately by adverse effects of dietary calorie restriction on muscle proteolysis.

Abstract
Abstract
During the period between 2000 and 2030, the number of persons older than 65 years is projected to grow from 550 to 937 million worldwide. Globally, this growth represents an increase from 6.9 to 12 %. Studies have found that 74.6 % of women and 67.4 % of men aged 65 years or older suffer from many clinical and subclinical syndromes and problems, including anorexia, undernutrition, weight loss, sarcopenia, and cachexia, which are often overlooked or managed inadequately. These issues are very common in the elder. The key clinical question is whether these changes in the elder are distinct entities or an interdependent continuum. In this article, we reviewed these issues of related basic, clinical knowledge. The purpose of this review is to enhance the recognition of anorexia, undernutrition, weight loss, sarcopenia, and cachexia.

Abstract
Undernutrition in older persons usually presents as weight loss and is predominantly due to protein energy wasting. The presentation of undernutrition is often subtle in older persons and there is a need to utilize screening tools and increasing physician awareness. There are multiple treatable causes of undernutrition in older persons. The major causes are anorexia, cachexia, sarcopenia, dehydration, malabsorption and hypermetabolism. This article also provides an overview of the use of nutritional supplements and an approach to managing protein energy wasting.

Abstract
Background Few studies exist on the validity of food frequency questionnaires (FFQs) administered to elderly people. The aim of this study was to assess the validity of a short FFQ on present dietary intake, developed specially for the AGES-Reykjavik Study, which includes 5,764 elderly individuals. Assessing the validity of FFQs is essential before they are used in studies on diet-related disease risk and health outcomes. Method 128 healthy elderly participants (74 y ± 5.7; 58.6% female) answered the AGES-FFQ, and subsequently filled out a 3-day weighed food record. Validity of the AGES-FFQ was assessed by comparing its answers to the dietary data obtained from the weighed food records, using Spearman's rank correlation, Chi-Square/Kendall's tau, and a Jonckheere-Terpstra test for trend. Result For men a correlation ≥ 0.4 was found for potatoes, fresh fruits, oatmeal/muesli, cakes/cookies, candy, dairy products, milk, pure fruit juice, cod liver oil, coffee, tea and sugar in coffee/tea (r = 0.40-0.71). A lower, but acceptable, correlation was also found for raw vegetables (r = 0.33). The highest correlation for women was found for consumption of rye bread, oatmeal/muesli, raw vegetables, candy, dairy products, milk, pure fruit juice, cod liver oil, coffee and tea (r = 0.40-0.61). An acceptable correlation was also found for fish topping/salad, fresh fruit, blood/liver sausage, whole-wheat bread, and sugar in coffee/tea (r = 0.28-0.37). Questions on meat/fish meals, cooked vegetables and soft drinks did not show a significant correlation to the reference method. Pearson Chi-Square and Kendall's tau showed similar results, as did the Jonckheere-Terpstra trend test. Conclusion A majority of the questions in the AGES-FFQ had an acceptable correlation and may be used to rank individuals according to their level of intake of several important foods/food groups. The AGES-FFQ on present diet may therefore be used to study the relationship between consumption of several specific foods/food groups and various health-related endpoints gathered in the AGES-Reykjavik Study.

Abstract
Food consumption surveys in the elderly come to the general conclusions that most elderly people outside institutions eat reasonably well. There is, however, tremendous variation in health status between older adults. The aging process is complex and influenced not only by factors intrinsic to the individual but also by extrinsic factors. The latter includes nutrition. In the various phases in the aging process, nutritional status and thus appropriate nutrition differ. Undernutrition is a great concern. In community-dwelling people older than 70 years, 5%-10% are undernourished, and for institutionalized elderly, this is up to 30%-65%. The cause is often inappropriate food consumption, and treatment is not always evidence based. National evidence-based dietary guidelines are mainly for healthy elderly people and vary between regions and even between institutes within the same region. To understand these differences, insight is required into the paradigm applied for nutritional science and the designs, selection of the older population, methodology, and endpoints of studies supplying the science behind the guidelines. A European project (Eurecca) compiles and harmonizes dietary guidelines. These activities underpin the need for sound evidence to improve the nutrition of older adults in different health phases. For frail elderly, there is also a plea to take into account results of studies on food satisfaction. First studies in this field show the effectiveness of an adapted social context for meals, appropriate nutritional care, and availability of tasty drinks and foods for selected groups of older adults. Because of the nutrient richness of dairy products and their good taste, these foods are helpful in the diet of healthy as well as frail elderly people. Key teaching points: Most elderly people eat reasonably well. There are, however, large differences in health status between elderly people and therefore also in nutrient requirements. Undernutrition is a main concern. In community-dwelling people older than 70 years, 5%-10% are undernourished, and for institutionalized elderly, this is up to 30%-65%. Evidence-based dietary guidelines are developed mainly for healthy elderly people and vary between regions. Harmonization will improve public health as well as clinical nutritional strategies. Given the nutrient density of dairy products, these products are included in balanced dietary advice for older adults.

Abstract
OBJECTIVES Anorexia is the most frequent modification of eating habits in old age, which may lead to malnutrition and consequent morbidity and mortality in older adults. We aimed to estimate the prevalence and factors associated to anorexia in a sample of Italian older persons living in different settings. Our secondary aim was to evaluate the impact of senile anorexia on nutritional status and on eating habits, as well as on functional status. DESIGN AND SETTING Observational study in nursing homes, in rehabilitation and acute geriatric wards, and in the community in four Italian regions (Lazio, Sicily, Emilia-Romagna, and Veneto). PARTICIPANTS 526 over 65 years old participants were recruited; 218 free-living subjects, 213 from nursing homes, and 96 patients from rehabilitation and acute geriatric wards in the context of a National Research Project (PRIN) from the Italian Ministry of Instruction, University and Research (2005-067913 "Cause e Prevalenza dell'Anoressia senile"). MEASUREMENTS Anthropometric and nutritional evaluation, olfactory, chewing, and swallowing capacity, food preferences, cognitive function, functional status, depression, quality of life, social aspects, prescribed drugs, and evaluation of gastrointestinal symptoms and pain. Laboratory parameters included prealbumin, albumin, transferrin, C-reactive protein, mucoprotein, lymphocyte count, as well as neurotransmitters leptin, and ghrelin. Anorexia was considered as ≥50% reduction in food intake vs. a standard meal (using 3-day "Club Francophone de Gériatrie et Nutrition" form), in absence of oral disorders preventing mastication. RESULTS The overall prevalence of anorexia was 21.2% with higher values among hospitalized patients (34.1% women and 27.2% men in long-term facilities; 33.3% women and 26.7% men in rehabilitation and geriatric wards; 3.3% women and 11.3% men living in the community) and in the oldest persons. Anorexic subjects were significantly less self-sufficient and presented more often a compromised nutritional and cognitive status. Diet composition analyses of anorexic older adults revealed a lower intake of all food groups and a general tendency to a monotonous diet. CONCLUSION Anorexia is a frequent condition in older Italians, particularly those hospitalized, with important consequences in the nutritional and functional status. The analysis of dietary components and its quality along with the frequency of intake of single food groups may be useful to plan intervention strategies aiming to improve the nutritional and health status of older adults with anorexia. An early detection of anorexia followed by an adequate intervention in older hospitalized patients to avoid further worsening of clinical and functional status is warranted.

Abstract
Sarcopenia is the key feature of frailty in older people and a major determinant of adverse health outcomes such as functional limitations and disability. Resistance training and adequate protein and energy intake are the key strategies for the management of sarcopenia. Management of weight loss and resistance training are the most relevant protective countermeasures to slow down the decline of muscle mass and muscle strength. The quality of amino acids in the diet is an important factor for stimulating protein synthesis. Vitamin D deficiency should be treated, and new pharmacologic approaches for sarcopenia are currently assessed.

Abstract
PURPOSE OF REVIEW The role of calorie restriction in humans is controversial. Recently, new data in monkeys and humans have provided new insights into the potential role of calorie restriction in longevity. RECENT FINDINGS A study in rhesus monkeys showed a reduction in aging-associated mortality. A number of controlled studies have suggested a variety of beneficial effects during studies of 6-12 months in humans. Major negative effects in humans were loss of muscle mass, muscle strength and loss of bone. SUMMARY Dietary restriction in rodents has not been shown to be effective when started in older rodents. Weight loss in humans over 60 years of age is associated with increased mortality, hip fracture and increased institutionalization. Calorie restriction in older persons should be considered experimental and potentially dangerous. Exercise at present appears to be a preferable treatment for older persons.

Abstract
PURPOSE OF REVIEW Anorexia and weight loss are associated with increased mortality in cachectic patients. The role of caloric supplementation is controversial. The purpose of this review is to examine the role of calorie supplementation in cachexia. RECENT FINDINGS Caloric supplementation improves outcomes in malnourished hospital patients and malnourished older persons. It may improve the quality of life in cancer patients and for those persons receiving palliative care. Caloric supplementation should include a balanced essential amino acid supplement given at least twice a day. The role of eicosapentanoic acid as a supplement is controversial. All caloric supplements should be given between and not with meals. SUMMARY Caloric supplementation rich in protein and with adequate vitamin D should be given between meals to all patients with cachexia.

Abstract
BACKGROUND The objective of this study was to identify the factors associated with recovery of prehospital function among older persons admitted to a nursing home with disability after an acute hospitalization. METHODS The analytic sample included 292 participants of an ongoing cohort study who had one or more admissions to a nursing home with disability after an acute hospitalization during nearly 10 years of follow-up, yielding a total of 364 "index" nursing home admissions. Information on nursing home admissions, hospitalizations, and disability in essential activities of daily living was ascertained during monthly telephone interviews. Data on potential predictors of functional recovery were collected during comprehensive assessments, which were completed every 18 months for 90 months. Participants were considered to have recovered if they were discharged home within 6 months of their nursing home admission at (or above) their prehospital level of function. RESULTS Recovery of prehospital function was observed for 115 (31.6%) of the 364 index nursing home admissions. In the multivariate analysis, the strongest associations were observed for the best category of performance, relative to the poorest category, for gross motor coordination (hazard ratio [HR] 13.5, 95% confidence interval [CI] 4.02-45.0) and manual dexterity (HR 10.0, 95% CI 2.94-34.3). Only two other factors were independently associated with recovery of prehospital function: not cognitively impaired (HR 3.0, 95% CI 1.46-6.14) and no significant weight loss (HR 1.96, 95% CI 1.06-3.63). CONCLUSIONS In the setting of an acute hospitalization leading to a nursing home admission with disability, the likelihood of recovering prehospital function is low. The factors associated with recovery include faster performance on tests of gross motor coordination and manual dexterity and the absence of cognitive impairment and significant weight loss.

Abstract
Inadequate nutritional intake is the predominant cause of malnutrition in older persons. It is one of the most common and devastating conditions in nursing home residents. It is multifactorial and treatment or nutrition care plans should try to address the main causes. Such plans often include means to stimulate appetite to prevent or treat anorexia. One important stimulus, which can be modulated easily, is the meal ambiance. This article deals with the theory or mechanism behind this meal ambiance stimulus, discusses some study results, and makes practical recommendations.

Abstract
Cachexia or wasting disease occurs commonly in diseases that have an overproduction of proinflammatory cytokines associated with them. The hallmarks of cachexia are loss of lean and adipose tissue, anorexia, anemia, memory disturbance, and sickness behavior. This review suggests that increased inducible nitric oxide synthase production in the hypothalamus leads to severe anorexia and that this is the pathway through which proinflammatory cytokines produce anorexia. Orexigenic peptides, such as neuropeptide, ghrelin, and orexin A, and anorectic peptides, such as leptin, produce their effects through neuronal nitric oxide synthase. Activation of neuronal nitric oxide synthase results in increased adenosine monophosphate kinase and a decrease in malonyl coenzyme A, leading to increased food intake.

Abstract
People are now living longer, largely because of a combination of falling rates of fertility and mortality, thus producing a greater proportion of older people in society. Thirty times more centenarians were alive in 2000 than in 1900, and the population growth in the elderly segment of society is expected to continue at an exponential rate. Vascular disease is responsible for more than a quarter of all deaths worldwide. More than 80% of individuals who die of coronary heart disease are older than 65 years. Although a myocardial infarction may be perceived as fatal, heart attacks do not always lead to death but to conditions such as congestive heart failure, ischemic cardiomyopathy, and angina, which greatly impact quality of life. These issues are only a few that must be contemplated when considering the clinical and economic effects of preventive therapies in the elderly population.

Abstract
PURPOSE OF REVIEW With the graying of the world's population, there is an increased interest in the physiological effects of aging. This review examines the physiological changes of the gut with aging and their clinical significance. RECENT FINDINGS Changes with aging in the gastrointestinal tract are variable, but in some cases they are responsible for a variety of symptoms. Thus, alterations in taste and smell, gastric motility, intestinal overgrowth and changes in gastrointestinal hormone release are the basis of the physiological anorexia of aging. Alterations in swallowing lead to silent aspiration. Changes in gastric emptying play a role in postprandial hypotension. Changes in gastrointestinal function can lead to constipation and fecal incontinence. Weakening of the colonic muscular wall produces diverticula. Achlorhydria is associated with malabsorption of some forms of iron and calcium. Vitamin D malabsorption aggravates the hypovitaminosis D that is so common in older persons. Changes in probiotics can lead to diarrhea and altered immune system. In the liver, aging is associated with delayed drug metabolism. SUMMARY Changes in the physiology of the gut play a role in the anorexia of aging, aspiration pneumonia, postprandial hypotension, constipation and fecal incontinence.

Abstract
OBJECTIVE The aim of this review of the literature is to report the factors which both contribute to the frailty syndrome and increase hip fracture risk in the elderly. This work is the fruit of common reflection by geriatricians, endocrinologists, gynecologists and rheumatologists, and seeks to stress the importance of detection and management of the various components of frailty in elderly subjects who are followed and treated for osteoporosis. It also sets out to heighten awareness of the need for management of osteoporosis in the frail elderly. DESIGN The current literature on frailty and its links with hip fracture was reviewed and discussed by the group. RESULTS The factors and mechanisms which are common to both osteoporosis and frailty (falls, weight loss, sarcopenia, low physical activity, cognitive decline, depression, hormones such as testosterone, estrogens, insulin-like growth factor-I (IGF-I), growth hormone (GH), vitamin D and pro-inflammatory cytokines) were identified. The obstacles to access to diagnosis and treatment of osteoporosis in the frail elderly population and common therapeutic pathways for osteoporosis and frailty were discussed. CONCLUSION Future research including frail subjects would improve our understanding of how management of frailty can can contribute to lower the incidence of fractures. In parallel, more systematic management of osteoporosis should reduce the risk of becoming frail in the elderly population.

Abstract
Unintended weight loss has a profound effect on morbidity and mortality in older persons. A therapeutic approach to unintended weight loss in older persons depends on correct classification. A careful differential diagnostic approach is mandatory, combined with nutritional and often pharmacological interventions. While starvation due to protein-energy undernutrition is widely regarded as the primary cause of loss of fat and fat-free mass in older persons, a failure to improve with nutritional replacement should trigger a consideration of other causes. Both sarcopenia and cachexia are resistant to hypercaloric feeding. Cachexia may be amenable to suppression of proinflammatory cytokines in known inflammatory disease states.

Abstract
Constipation and irritable bowel syndrome are very common in older persons. Constipation is over diagnosed and over treated in older persons. Lifestyle changes, osmotic laxatives, and lubiprostone are the approaches of choice for the management of constipation. Irritable bowel syndrome should be considered in the differential diagnosis of abdominal pain, diarrhea and constipation in older persons.
