Causes of weight loss in a community nursing home

Trends in Dehydration in Older People: Identifying Landmark Scientific Contributions

BACKGROUND

Dehydration and low fluid intake cause the most prevalent electrolyte imbalance in older adults and increase their morbi-mortality.

OBJECTIVE

To analyse the scientific production on dehydration in older adults.

METHODS

A bibliometric analysis was performed using the Web of Science Core Collection database. The data were analysed using two software programs, the Bibliometric package for RStudio version 4.2.2, and VOSviewer 1.6.18 for the analysis of the scientific production, authors, citations, countries and collaborations, journals, research areas, and keywords.

RESULTS

A total of 205 articles were selected. An increase in the number of publications has been observed since 2012, with 2021 being the most productive year. With respect to scientific production, although the USA had the most publications, the two most prolific authors were affiliated with an institution located in the UK, with this country having the most collaborations with other countries in the development of the subject matter. The co-occurrence analysis indicated that the words with the highest occurrence were dehydration (n = 103), hydration (n = 39), prevalence (n = 30), mortality (n = 29), and thirst (n = 29).

CONCLUSIONS

This is the first bibliometric analysis that shows the publication trends on dehydration in older adults. Although the number of publications is limited, they have increased in number in the last few years. The research trends are centred on the prevalence of dehydration and its related factors. More studies are needed that are centred on interventions to correct the problem, to help fight against the electrolyte imbalances that occur, and to reduce the morbi-mortality associated with this condition.

Recognising eating disorders in older people

Changes in eating behaviours, weight and mental health in older people may be related to psychological distress and indicate the presence of a diagnosable eating disorder, rather than 'anorexia of ageing'. Eating disorders in older people may be overlooked because signs and symptoms are assumed to be part of normal ageing. The role of nurses in the care of older people with eating disorders is likely to be detection, referral and support in accessing specialist intervention. This article offers an overview of eating disorders in older people and discusses why they may arise, why they may not be detected and how to recognise them. The authors describe a framework that nurses can use when assessing older people to determine whether they may have an eating disorder.

Determinants of nutritional status among old age population in eastern Ethiopia: a general linear model approach

As the world's aging population grows, nutrition and health issues are becoming a major concern. The aim of the present study was to identify the factors associated with nutritional status among old age population. A community-based cross-sectional study was employed among randomly selected 739 elders over the age of 60 in Dire Dawa City administration, eastern Ethiopia. The validated full mini nutritional assessment tool and appetite test (SNAQ) was used to assess the nutritional status of the study population. Considering the ranked nature of the data, a bivariate and multivariable ordinal logistic regression model (under the generalised linear model) was conducted, with crude and adjusted odds ratios reported along with 95 % confidence intervals. Statistically significant associations are declared at P-value less than 0⋅05. In this study, 22 % (95 % CI: 19 %, 25 %) of elders were malnourished. Participants with >75 years old (AOR 4⋅95; 95 % CI 1⋅54, 8⋅4), being female (AOR 1⋅6; 95 % CI 1⋅1, 2⋅2), illiterate (AOR 1⋅5; 95 % CI 1⋅01, 2⋅2), severe depression (AOR 13⋅9; 95 % CI 8⋅2, 23⋅7) and with poor appetite (AOR 3⋅3; 95 % CI 2⋅3, 4⋅8) were important predictors of malnutrition among older age group. We found that the prevalence of malnutrition and the risk of malnutrition is a public health concern that warrants intervention in the area. Advanced age, illiteracy, depression and poor appetite were important risk factors for malnutrition among older age group. The identified risk factors will guide public health professionals and programmes in the design, implementation of interventions to improve the nutritional status of older age group.

Falls may trigger body weight decline in nursing home residents

OBJECTIVES

The effect of falls on changes in body weight is still unknown. This study investigated the extent to which falls can modify the course of body weight in nursing home residents, and aimed to identify the factors that might modulate this effect.

METHODS

The sample included 132 residents aged ≥60 y who had experienced at least one fall after nursing home admission. Body weight was measured monthly in the 6 mo after the fall in the entire sample, and also in the 6 mo prefall in a subsample (n = 111). Sociodemographic and health data were obtained from medical records. Linear mixed models were used to estimate the average monthly changes in body weight after the fall in the total sample, and as a function of the sociodemographic and medical factors.

RESULTS

Falls modified the course of body weight in the total sample (β = -0.28, 95% confidence interval, -0.44 to -0.12, for the change in slope before and after fall) in all age classes and especially in individuals with severe cognitive impairment who received less-frequent informal visits (β = -0.55, 95% confidence interval, -0.87 to -0.22). Individuals aged ≥90 y and those with severe cognitive impairment had a steeper monthly weight decline in the 6 mo postfall, of 0.23 and 0.35 kg greater, respectively, than their younger and cognitively healthier counterparts.

CONCLUSIONS

Falls may trigger a body weight loss in nursing home residents, especially in the oldest old people and those with severe cognitive impairment who receive little support from informal caregivers. These findings highlight the importance of monitoring nutritional status of people who live in institutions after falls.

A Predictive Model for the Risk of Cognitive Impairment in Patients with Gallstones

OBJECTIVES

Gallstones can cause malnutrition in patients and further lead to cognitive impairment. This study is aimed at constructing a validated clinical prediction model for evaluating the risk of developing cognitive impairment from gallstones.

METHODS

The study was a single-centre crosssectional study. Four models or methods (SVM-RFE, random forest model, Lasso model, and logistics analysis) were analyzed and compared regarding their predictive performance. The model with the best classification performance and predictive power was selected. The AUC index, C-index, and calibration curves were applied to the chosen model to further evaluate its classification and prediction performance. Finally, the nomogram was plotted, and the clinical usability, efficacy, and safety of the nomogram were assessed using decision curve analysis (DCA).

RESULTS

This study included a total of 294 patients with gallstones, of which 110 had cognitive impairment. Factors such as gender, age, education, place of birth, history of alcohol consumption, abdominal circumference, sarcopenia, diabetes, anaemia, depression, and Pittsburgh Sleep Quality Index (PSQI) were incorporated into the model for nomogram construction. The calibration curve showed that the nomogram had good classification performance. Furthermore, the C-index of the model was 0.778 (95% CI, 0.674-0.882) in the test group. The DCA curves indicated that the constructed model had strong clinical applicability, efficacy, and safety.

CONCLUSIONS

This study constructed a cognitive impairment risk prediction model for patients with gallstones with good classification and predictive power. The constructed predictive model allows us to screen patients with gallstones and at high risk of cognitive impairment. These efforts might also help to further increase patient compliance, assist healthcare professionals to better manage patients with gallstones, and ultimately improve their overall health status and quality of life. Future clinical studies should further evaluate the accuracy and clinical usability of this model.

Assessment of Body Composition and Dietary Intake in Nursing-Home Residents: Could Lessons Learned from the COVID-19 Pandemic Be Used to Prevent Future Casualties in Older Individuals?

The population of older adults, especially those living in the nursing homes, is growing. The sedentary lifestyle and possible poor nutrition in nursing homes place residents (NHRs) at risk for body composition impairments, malnutrition, and, subsequently, numerous chronic diseases. The aim of this study was to assess body composition (including body fluids) and dietary intake in NHRs. The association between osteosarcopenic adiposity syndrome (OSA) and its components, osteopenic adiposity (OA), sarcopenic adiposity (SA), and adiposity-only (AD), and specific macro- and micro-nutrients was evaluated as well. The study included 84 participants (82.1% women), aged 65.3-95.2 years. Body composition was assessed with an advanced bioelectrical impedance device BIA-ACC® and dietary intake was assessed via 24-h recall and analyzed using "Nutrition" software. The majority (95%) of participants were overweight with a high body fat and low muscle and bone mass, leading to a high prevalence of OSA (>50%), OA (13%), and AD (26%). There were only a few participants with SA, and they were not analyzed. The highest extracellular water/total body water ratio was observed in the OSA participants, indicating a heightened inflammatory state. Participants in all three body composition categories had a similar nutrient intake, with protein, fiber, omega-3 fatty acids, and almost all micronutrients being far below recommendations. In conclusion, a high prevalence of OSA among NHRs accompanied by a poor dietary intake, could place these residents at a very high risk for COVID-19 infections. Therefore, optimization of body composition and nutritional status should be included along with standard medical care in order to provide better health maintenance, particularly in the COVID-19 era.

Approach to Patients with Unintentional Weight Loss

Unintentional weight loss is a common clinical problem with a broad differential diagnosis that is clinically important because of the associated risks of morbidity and mortality. Community-dwelling adults are often diagnosed with malignancy, nonmalignant gastrointestinal disorders, and psychiatric disorders as the cause of unintentional weight loss, whereas institutionalized older adults are diagnosed most often with psychiatric disorders. Up to a quarter of patients do not have a diagnosis after comprehensive workup, and close follow-up is warranted. Treatment involves management of underlying causes.

Prevalence of Malnutrition and Depression in Older Adults Living in Nursing Homes in Mexico City

This study evaluated the association between nutritional status, depressive symptoms, and the number of prescription drugs taken by older adults living in nursing homes in Mexico City. In a cross-sectional study, 262 participants were subjected to anthropometric and nutritional (Mini Nutritional Assessment (MNA)) evaluations; additionally, their depression (Geriatric Depression Scale (GDS)) and functional status were assessed. Multiple logistic regression was used for identifying factors associated with the risk of malnutrition/malnourishment. The mean age of participants was 83.1 ± 8.6 years. A total of 59.9% and 21.1% were at risk of malnutrition and malnourished, respectively. With respect to depression, 27.9% of the participants had mild depression, while 11.4% showed severe depression. An inverse correlation between MNA evaluations and depression scores was found (Spearman's ρ = -0.4624, p < 0.001); residents with a better nutritional status had lower depression scores. Individuals with depressive symptoms were approximately five times more likely to be at risk of malnutrition or malnourished (OR = 5.82, 95% CI = 2.27-14.89) than individuals without depression. Residents taking three or more prescription drugs daily (OR = 1.83, 95% CI = 1.27-2.63, p < 0.001) were more likely to be at risk of malnutrition or malnourished. In summary, poor nutritional status was associated with depression, while the intake of numerous prescription drugs was associated with being at risk of malnutrition or malnourished.

Factors associated with food intake, nutritional status, and function among nursing home residents with dementia

Declined food intake is prevalent among long-term care (LTC) residents with dementia and associated with deleterious health outcomes. This study explores food intake, nutritional status, and function and its associated factors in LTC residents with dementia. Data from 82 LTC residents with dementia were used in this secondary analysis. The majority of residents were either malnourished or at risk of being malnourished and demonstrated a worse appetite than previously described in the literature. Comorbid illness, depressed mood, and appetite were associated with 37.1% of the variance in food intake over 30 days. Dementia level and appetite were associated with 22.2% of the variance in nutritional status. Food intake and nutritional status were associated with 29.1% of the variance in function. This study also highlights a new demographic that may require extra assistance in combating declined food intake: LTC residents with dementia who reside in a facility that follows restrictive food practices such as a kosher diet. The potential reversibility of factors associated with food intake and nutritional status provides opportunities for intervention.

Amyloid-beta burden predicts prospective decline in body mass index in clinically normal adults

In the present study, we tested the hypothesis that higher amyloid-beta (Aβ) burden at baseline is associated with greater longitudinal decline in body mass index (BMI) in clinically normal adults. Participants from the Harvard Aging Brain Study (n = 312) and the Alzheimer's Disease Neuroimaging Initiative (n = 336) underwent Aβ positron emission tomography at baseline. BMI was assessed longitudinally over a median of >4 years. Linear mixed models showed that higher baseline Aβ burden was significantly associated with greater decline in BMI in both the Harvard Aging Brain Study (t = -1.93; p = 0.05) and Alzheimer's Disease Neuroimaging Initiative cohorts (t = -2.54; p = 0.01), after adjusting for covariates, including cognitive performance and depressive symptoms. In addition, the association of Aβ burden with longitudinal decline in BMI persisted in both cohorts after excluding participants with diabetes/endocrine disturbances and participants classified as underweight or obese (BMI <18.5 or >30). These findings suggest that decline in BMI in clinically normal adults may be an early manifestation related to cerebral amyloidosis that precedes objective cognitive impairment. Therefore, unintentional BMI decline in otherwise healthy individuals might alert clinicians to increased risk of Alzheimer's disease.

The Assessment of Eating Pleasure among Older Adults: Development and Preliminary Validation of the Anticipatory and Consummatory Eating Pleasure (ACEPS)

OBJECTIVE

Maintaining eating pleasure as long as possible is one of the determinants that contributes to and encourages good nutrition in the ageing population. Our study aimed to translate, adapt to the context of food and validate the Temporal Experience of Pleasure Scale (which distinguishes anticipatory and consummatory experiences of pleasure) in a food dependent older French population.

DESIGN

Prospective validation study.

SETTING

199 participants dependent for their meals, over 65 years old and living at home.

MEASUREMENTS

A pool of 16 self-reported items constituted the initial version of the anticipatory and consummatory eating pleasure scale (ACEPS). Demographic data, nutritional status, appetite and depressive mood were also assessed.

RESULTS

The exploratory factorial analysis and also the confirmatory factor analysis highlighted a two-factor model: anticipatory eating pleasure (four items) and consummatory eating pleasure (four items). The ACEPS showed good internal consistency. A higher score on the ACEPS positively correlated with appetite. Consummatory eating pleasure positively correlated with nutritional status and negatively correlated with depressive moods. The oldest-old and also those receiving a meals-on-wheels service had lower scores for anticipatory pleasure (r=-.14, p<.03).

CONCLUSION

To our knowledge, the ACEPS is the first comprehensive measure of eating pleasure distinguishing anticipatory and consummatory pleasure. This short measure, easily applicable on older people with vulnerability, allows early identification and intervention preventing malnutrition and decline in health. Specifically, encouraging anticipatory eating pleasure may be a first step to improving food intake among older adults.

The cause of anorexia and proportion of its recovery in older adults without underlying disease: Results of a retrospective study

Aim

It is difficult to determine whether or not end-of-life care is necessary for frail older adults complaining of anorexia without underlying disease, such as cancer or organ failure. The main reason for this is the lack of the specification of the anorexia cause and no understanding of the cause-providing factor and the prognostic factor. This study aimed to clarify the cause of anorexia, and the determinant of the cause and recovery from anorexia.

Methods

Retrospective chart reviews were conducted on patients with anorexia without an underlying disease who were aged ≥65 years and visited the emergency department of a single tertiary care center between 2016 and 2017. Patient characteristics at hospital visit, the cause of anorexia, and diagnostic modalities were summarized. The diagnosis-providing rate, recovery rate, and the association between them were analyzed.

Results

Eighty-three patients (mean age 82.3 years; 50.6% male) were investigated. In 67 patients (81%), the causes of anorexia were identified, including 18 patients (22%) with infection, 13 (16%) with benign gastrointestinal diseases, and 7 (8%) with cardiovascular diseases. In 16 patients (19%), the causes of anorexia were not identified despite examinations. The modality that most contributed to diagnosis was plain computed tomography followed by blood tests. The value regarding information in history-taking and physical examinations was limited. Sixty-five patients (78%) recovered. Only 73% of patients with a definite cause recovered; all patients with an unknown cause recovered.

Conclusions

Older adults with anorexia are not always at the end of life, and efforts to identify the cause are crucial. Moreover, it is vital to realize the limitations associated with the treatment of infections and cardiovascular diseases.

Predictability of a modified Mini- Nutritional- Assessment version on six-month and one-year mortality in hospitalized geriatric patients: a comparative analysis

Recently we introduced a modified Mini Nutritional Assessment (MNA) Short Form (MNA-SF) and Long Form (MNA-SF) with operationalization of the ‘mobility’ and ‘neuropsychological problems’ items of the MNA using scores on Barthel Index mobility item and Mini Mental State Examination and Geriatric Depression Scale scores. We have now evaluated the abilities of this modified MNA-SF and MNA-LF to predict mortality in comparison with the standard MNA-SF and MNA-LF and the Nutritional Risk Screening 2002 (NRS 2002) and the Malnutrition Universal Screening Tool (MUST). A prospective analysis was performed in 240 hospitalised geriatric patients aged ≥ 65 years. Malnutrition and/or malnutrition risk were assessed using the modified MNA-SF and MNA-LF, the standard MNA-SF and MNA-LF, and the NRS 2002 and MUST. The modified MNA-SF and MNA-LF and the standard MNA-SF and MNA-LF assessments (all p < 0.05), but not NRS 2002 or MUST (all p ≥ 0.05), predicted six-month and/or one-year mortality. Prediction of six-month and/or one-year mortality by the modified MNA-SF was comparable with predictions by the standard MNA-SF and MNA-LF (all p ≥ 0.05). The modified MNA-LF showed better prediction of six-month and one-year mortality than the standard MNA-SF and MNA-LF (all p < 0.05). The modified MNA-LF (all adjusted p < 0.05), but none of the other instruments (all adjusted p ≥ 0.05), predicted six-month and one-year mortality independently of age, sex, frailty, comorbidity and ADL disability burden. The modified MNA-SF and MNA-LF emerged as potentially valuable tools for predicting mortality in patients hospitalised on geriatric wards.

Depressive symptoms and nutritional status in the frail older adults

OBJECTIVES

The purpose of this study is to determine the relationship between depressive symptoms and nutritional status in the frail older adults.

METHODS

This study uses a cross-sectional, descriptive, and correlational design. A questionnaire was used to collect demographic data, and the Taiwan International Physical Activity Questionnaire Form Geriatric Depression Scale-Short Form Charlson Comorbidity Index, and Mini-Nutritional Assessment Short-Form were used to measure depression and nutritional status, respectively. Data were analyzed by independent-t tests, chi-square tests, spearman correlations, and multiple linear regressions.

RESULTS

Of the total of 94 frail older adults, 17 (18.09%) had depressive symptoms (GDS > 5). The average MNA-SF score was 11.38 (SD = 2.45), 31 (32.98%) participants had a risk of malnutrition and 12 (12.77%) were malnourished. Participants' reports of dissatisfaction with their lives (72.1%) and feeling terrible about their lives (58.14%) were associated with a risk of malnutrition. Elderly age, multiple comorbidities, and high level of depressive symptoms were at increased risk of malnutrition.

CONCLUSION

When clinicians are faced with a high-risk group, such as elderly patients with multiple comorbidities and depressive symptoms, they should perform an immediate assessment of nutritional status. If a risk of malnutrition is found, adequate nutrition and health care should be provided.

Nutritional status is associated with the degree of cognitive impairment and depressive symptoms in a Greek elderly population

Introduction: Cognitive impairment and malnutrition are two important public health issues in the elderly, which have been associated with their mental health.Aims: This study aims to evaluate the nutritional status of an elderly population in Greece, and its association with the grade of cognitive decline, anthropometric measures and psychological status.Materials and Methods: A total of 2092 elderly men and women were enrolled from seven Greek cities. Mini Nutritional Assessment (MNA), Mini Mental State Examination (MMSE) and Geriatric Depression Scale (GDS) questionnaires were used to assess the impact of nutritional status on cognitive abilities and psychological status of the participants.Results: Of the elderly, 35.0% were at risk of malnutrition and 11.3% were malnourished, while 34.4% of the participants had impaired cognitive function, and 32.3% showed depressive symptoms. Malnutrition was more frequently observed in participants presenting cognitive impairment, and depressive symptoms. In multiple regression analysis, nutritional status was independently associated with cognitive and psychological status.Conclusions: A high prevalence of malnutrition was recorded in this elderly population sample, which was directly associated with cognitive impairment and depression. Diagnostic tools such as MNA, MMSE, and GDS are strongly recommended to be applied as a routine clinical practice in the elderly to timely and effectively address these health problems.

Disordered eating in older people: Some causes and treatments

This overview considers causes of disordered eating, including eating disorders, in older people. Eating disorders are becoming more common in older adults and research has shown a related mortality of 21%. The wide range of medical and pharmacological causes of weight loss in older people means that eating disorders may go undetected, occurring insidiously and surreptitiously.

Learning Objectives

• Be aware of the numerous causes of weight loss in older people, and understand that eating disorders are not about weight but about control

• Appreciate that physical and mental health problems and polypharmacy affect eating and weight

• Understand that successful management focuses on a combination of pharmacological and behavioural interventions

Psychosocial correlates of unintentional weight loss in the second half of life in the German general population

Background

Unintentional weight loss (UWL) is common in older age and associated with adverse outcomes including mortality. The aim of the present study was to determine psychosocial correlates of UWL.

Methods

Data were derived from a large, nationally representative study of community-dwelling individuals in the second half of life (40 years and over) in Germany in 2014 (n = 7,933). Data on UWL were assessed in face-to-face interviews as unintentional loss of more than 5kg (11 pounds) in weight in the past 12 months, and data on psychosocial factors were recorded in self-administered questionnaires.

Results

Multiple logistic regressions revealed that UWL was positively associated with depressive symptoms and positive affect, whereas it was negatively associated with self-esteem. Individuals with UWL were more likely to feel lonely and perceive themselves as socially excluded.

Conclusion

The findings of important psychosocial correlates of UWL may help to identify individuals at risk for UWL in older age. This is in particular important since interventions to treat this phenomenon in older age are available that reduce adverse consequences resulting from UWL.

Unintentional weight loss: Clinical characteristics and outcomes in a prospective cohort of 2677 patients

BACKGROUND

Whereas there are numerous studies on unintentional weight loss (UWL), these have been limited by small sample sizes, short or variable follow-up, and focus on older patients. Although some case series have revealed that malignancies escaping early detection and uncovered subsequently are exceptional, reported follow-ups have been too short or unspecified and necropsies seldom made. Our objective was to examine the etiologies, characteristics, and long-term outcome of UWL in a large cohort of outpatients.

METHODS

We prospectively enrolled patients referred to an outpatient diagnosis unit for evaluation of UWL as a dominant or isolated feature of disease. Eligible patients underwent a standard baseline evaluation with laboratory tests and chest X-ray. Patients without identifiable causes 6 months after presentation underwent a systematic follow-up lasting for 60 further months. Subjects aged ≥65 years without initially recognizable causes underwent an oral cavity examination, a videofluoroscopy or swallowing study, and a depression and cognitive assessment.

RESULTS

Overall, 2677 patients (mean age, 64.4 [14.7] years; 51% males) were included. Predominant etiologies were digestive organic disorders (nonmalignant in 17% and malignant in 16%). Psychosocial disorders explained 16% of cases. Oral disorders were second to nonhematologic malignancies as cause of UWL in patients aged ≥65 years. Although 375 (14%) patients were initially diagnosed with unexplained UWL, malignancies were detected in only 19 (5%) within the first 28 months after referral. Diagnosis was established at autopsy in 14 cases.

CONCLUSION

This investigation provides new information on the relevance of follow-up in the long-term clinical outcome of patients with unexplained UWL and on the role of age on this entity. Although unexplained UWL seldom constitutes a short-term medical alert, malignancies may be undetectable until death. Therefore, these patients should be followed up regularly (eg yearly visits) for longer than reported periods, and autopsies pursued when facing unsolved deaths.

Training Nonnursing Staff to Assist with Nutritional Care Delivery in Nursing Homes: A Cost-Effectiveness Analysis

OBJECTIVES

To determine the effect and cost-effectiveness of training nonnursing staff to provide feeding assistance for nutritionally at-risk nursing home (NH) residents.

DESIGN

Randomized, controlled trial.

SETTING

Five community NHs.

PARTICIPANTS

Long-stay NH residents with an order for caloric supplementation (N = 122).

INTERVENTION

Research staff provided an 8-hour training curriculum to nonnursing staff. Trained staff were assigned to between-meal supplement or snack delivery for the intervention group; the control group received usual care.

MEASUREMENTS

Research staff used standardized observations and weighed-intake methods to measure frequency of between-meal delivery, staff assistance time, and resident caloric intake.

RESULTS

Fifty staff (mean 10 per site) completed training. The intervention had a significant effect on between-meal caloric intake (F = 56.29, P < .001), with the intervention group consuming, on average, 163.33 (95% CI = 120.19-206.47) calories per person per day more than the usual care control group. The intervention costs were $1.27 per person per day higher than usual care (P < .001). The incremental cost-effectiveness ratio for the intervention was 134 kcal per dollar. The increase in cost was due to the higher frequency and number of snack items given per person per day and the associated staff time to provide assistance.

CONCLUSION

It is cost effective to train nonnursing staff to provide caloric supplementation, and this practice has a positive effect on residents' between-meal intake.

Validation of the Spanish version of the Edinburgh feeding evaluation in dementia scale applied to institutionalized older persons with dementia: a study protocol

Aim

The aim of this study was to obtain a Spanish version of the Edinburgh Feeding Evaluation in Dementia Scale version, to assess its reliability for use by medical staff and caregivers at residential care homes, to evaluate by confirmatory methods its construct validity. A further aim was to determine the criterion validity with respect to biochemical markers of malnutrition such as serum albumin, transferrin, cholesterol and lymphocytes, the body mass index and the mini nutritional assessment.

Design

Clinimetric cross‐validation study.

Methods

Institutionalized subjects with dementia will be observed while consuming meals and evaluated with the instrument independently by nurses and caregivers.

Cost-Effectiveness of Nutrition Intervention in Long-Term Care

OBJECTIVES

To determine the cost-effectiveness of two nutrition interventions on food, beverage, and supplement intake and body weight.

DESIGN

Randomized, controlled trial.

SETTING

Five skilled nursing home facilities.

PARTICIPANTS

Long-stay residents with orders for nutrition supplementation (N = 154).

INTERVENTION

Participants were randomized into a usual care control group, an oral liquid nutrition supplement (ONS) intervention group, or a snack intervention group. Research staff provided ONS, according to orders or a variety of snack foods and beverages twice per day between meals, 5 days per week for 24 weeks and assistance to promote consumption.

MEASUREMENTS

Research staff independently weighed residents at baseline and monthly during the 24-week intervention. Resident food, beverage and supplement intake and the amount of staff time spent providing assistance were assessed for 2 days at baseline and 2 days per month during the intervention using standardized observation and weighed intake procedures.

RESULTS

The ONS intervention group took in an average of 265 calories more per day and the snack intervention group an average of 303 calories more per day than the control group. Staff time required to provide each intervention averaged 11 and 14 minutes per person per offer for ONS and snacks, respectively, and 3 minutes for usual care. Both interventions were cost-effective in increasing caloric intake, but neither intervention had a significant effect on body weight, despite positive trends.

CONCLUSION

Oral liquid nutrition supplements and snack offers were efficacious in promoting caloric intake when coupled with assistance to promote consumption and a variety of options, but neither intervention resulted in significant weight gain.

Malnutrition and Dysphagia in long-term care: a systematic review

Determining the co-occurrence of malnutrition and dysphagia is important to understand the extent to which swallowing impairment contributes to poor food intake in long-term care (LTC). This review investigated the impact of dysphagia on malnutrition in LTC by synthesizing the results of published literature. Seven electronic databases were used to search for English-language publications reporting malnutrition and dysphagia in LTC facilities from 1946 to 2013. Fourteen studies were eligible for inclusion. Overall, the literature on the co-occurrence of malnutrition and dysphagia in LTC shows a paucity of high-quality evidence. Articles reviewed lacked consistent definitions for both conditions. Methods used to confirm each diagnosis also differed and were of questionable validity. Based on a review of the literature, evidence of the existence of concurrent concerns with respect to malnutrition and dysphagia emerges. The reported frequency of participants in LTC with dysphagia ranges from 7% to 40%, while the percentage of those who were malnourished ranges from 12% to 54%. Due to discrepancies used to describe and measure these conditions, it is difficult to determine the exact prevalence of either condition separately, or in combination. Consequently, the impact of dysphagia on malnutrition must be considered and studied using valid definitions and measures.

The impact of depression and malnutrition on health-related quality of life among the elderly Iranians

INTRODUCTION

The present study aimed to assess the association between nutritional status and depressive symptoms among elderly Iranians and to explore their impact on their Health-Related Quality of Life (HRQoL).

METHODS

In this cross-sectional study, 447 elders aging from 55 to 85 years were randomly selected and completed the Iranian version of Geriatric Depression Scale-15 (GDS), Mini Nutritional Assessment (MNA), and the Iranian version of Short Form Health Survey (SF-36).

RESULTS

Out of the 447 elderly, 72.1% were female with the mean age of 65.99 ± 7.89 years. The prevalence of depression was 38.1%. In addition, the SF-36 sub-scores tended to be lower among the elders with depressive symptoms according to GDS. The Physical Functioning (PF), Bodily Pain (BP), Role Physical (RP), Role Emotional (RE), and Mental Health (MH) dimensions of the SF-36 were also statistically poorer in the elders with depression. The mean MNA score was 24.6 ± 2.7; 35.4% of the participants were malnourished or at risk of malnutrition and 64.6% were adequately nourished. The sub scores of SF-36 were significantly lower in the elders with impaired nutritional status.

CONCLUSIONS

Considering the importance of the association among psychological and nutritional problems and HRQoL in caring for and promoting the welfare of the elders, this study provided fundamental information and a basis for further evaluation of this issue in developing and undeveloped countries.

Factors associated with poor nutritional status among community dwelling Lebanese elderly subjects living in rural areas: results of the AMEL study

OBJECTIVES

This study aimed to assess the nutritional status, measured by MNA, and its association with socio-demographic indicators and health related characteristics of a representative sample of community dwelling elderly subjects.

DESIGN

Cross-sectional study.

SETTING

Community dwelling elderly individuals living in rural communities in Lebanon.

PARTICIPANTS

1200 elderly individuals aged 65 years or more.

MEASUREMENTS

Socio-demographic indicators and health related characteristics were recorded during a standardized interview. Nutritional status was assessed through Mini Nutritional Assessment (MNA). The 5-item GDS score and the WHO-5-A score were used to assess mood, whereas Mini Mental Status (MMS) was applied to evaluate cognitive status.

RESULTS

The prevalence of malnutrition and risk of malnutrition was 8.0% respective 29.1% of the study sample. Malnutrition was significantly more frequent in elderly subjects aged more than 85 years, in females, widowed and illiterate people. Moreover, participants who reported lower financial status were more often malnourished or at risk of malnutrition. Regarding health status, poor nutritional status was more common among those reporting more than three chronic diseases, taking more than three drugs daily, suffering from chronic pain and those who had worse oral health status. Also, depressive disorders and cognitive dysfunction were significantly related to malnutrition. After multivariate analysis following variables remained independently associated to malnutrition: living in the governorate of Nabatieh (ORa 2.30, 95% CI 1.35 -3.93), reporting higher income (ORa 0.77, 95% CI 0.61-0.97), higher number of comorbidities (ORa 1.22, 95% CI 1.12-1.32), chronic pain (ORa 1.72, 95% CI 1.24-2.39), and depressive disorders (ORa 1.66, 95% CI 1.47-1.88). On the other hand, better cognitive functioning was strongly associated with decreased nutritional risk (ORa 0.27, 95%CI 0.17-0.43).

CONCLUSION

Our results highlighted the close relationship between health status and malnutrition. The identification of potential predictive factors may allow better prevention and management of malnutrition in elderly people.

Local flap therapy for the treatment of pressure sore wounds

The aim of this study was to analyse the effectiveness of an interdisciplinary cooperation between conservative and surgical disciplines for the treatment of pressure sores (PS). From January 2004 to December 2005, a single-centre study was performed with paraplegic and tetraplegic patients presenting with PS grades III-V. Outcome measures were defect size, grade, method of reconstruction, complication and recurrence rate as well as average length of hospitalisation. A total of 119 patients aged 22-84 years with totally 170 PS were included. The most common PS were located in the ischial region (47%), followed by the sacral (18%), trochanteric (11%), foot (9%) and the malleolar (8%) regions. Defect sizes ranged between 4 and 255 cm(2) . Grade IV was the most common PS (68%), followed by grade III (30%) and grade V (2%) PS. For wound closure, fasciocutaneous flaps were used most frequently (71%), followed by skin grafts (10%) and myocutaneous flaps (7%). Postoperative follow-up ranged between 6 and 38 months. The overall complication and recurrence rate was 26% and 11%, respectively. If no complication occurred, the average duration of hospitalisation stay after the first debridement was 98 ± 62 days. In conclusion, our treatment concept is reliable, effective and results in a low recurrence rate. The complication rate, even though favourable when compared with the literature, still needs to be improved.

Relationship between depression and risk of malnutrition among community-dwelling young-old and old-old elderly people

OBJECTIVES

This study explores the association between nutritional status and depression among healthy community-dwelling young-old (aged 65-74) and old-old elderly (aged 75 and older).

METHOD

A cross-sectional design was implemented. A total of 274 community-dwelling older individuals (142 young-old; 132 old-old) were assessed using the Geriatric Depression Scale (GDS), Mini-Nutritional Assessment Short-Form (MNA-SF) and Life-Space Assessment. Logistic regression analysis was used to determine if depression was independently associated with risk of malnutrition, stratified by age (young-old vs. old-old).

RESULTS

In the logistic regression model for young-old, being at risk of malnutrition (MNA-SF (≦11) was strongly associated with depression (GDS (≧5;) (likelihood ratio ν = 6.26; 95% confidence interval [CI]: 1.91-20.49). In contrast, in the old-old group, the model was not statistically significant.

CONCLUSION

Depression and nutritional status were strongly correlated in young-old but not in old-old community-dwelling elderly. This study reveals that not only the factors correlated with but also the symptoms of depression may vary among different age stratifications of the elderly.

Anorexia and eating patterns in the elderly

Objectives

To evaluate the change in eating habits occurring in community- dwelling and institutionalized elderly subjects with senile anorexia.

Design

Cross- sectional, observational.

Setting

Community, nursing homes and rehabilitation or acute care facilities in four Italian regions.

Participants

A random sample of 526 subjects, aged 65 years and older (217 free living individuals, 213 residents in nursing homes, and 93 patients in rehabilitation and acute wards).

Measurements

All subjects underwent a multidimensional geriatric evaluation of: nutritional status, anthropometric parameters, health and cognitive status, depression, taste, chewing and swallowing function, and some hormones related to appetite. Diet variety was assessed, considering the frequency of consumption of different food groups (milk and dairy products; meat, fish, and eggs; cereals and derivatives; fruit and vegetables).

Results

In anorexic elderly subjects the global food intake was reduced, and the eating pattern was characterized by the reduced consumption of certain food groups (“meat, eggs and fish” and “fruit and vegetables”) whereas the frequency of consumption of milk and cereals remained almost unchanged. Nutritional parameters were significantly better in normal eating subjects and correlated with diet variety.

Conclusion

Because of the high prevalence of senile anorexia in the geriatric population and its impact on the nutritional status, further research should be prompted to establish an intervention. protocol allowing the early diagnosis of anorexia of aging, aimed at identifying its causes and at optimizing treatment of anorexic patients.

Nutrition screening of older people in a community general practice, using the MNA-SF

BACKGROUND

OBJECTIVE

The study aimed to determine the prevalence of malnutrition risk in a population of older people (aged 75 years and over) attending a community general practice and identify characteristics of those classified as malnourished or at risk of malnutrition.

DESIGN

Cross-sectional study of nutritional risk screen conducted over a six month period.

PARTICIPANTS AND SETTING

Patients attending a general practice clinic in Victoria, Australia, who attended for the "75 plus" health assessment check.

MEASUREMENTS

The Mini Nutritional Assessment Short Form (MNA®-SF) was included as part of the health assessment. Information was collected on living situation, co-morbidities, independence with meal preparation and eating, number of medications. Height and weight was measured and MNA®-SF score recorded.

RESULTS

Two hundred and twenty five patients attending a general practice for a health assessment with a mean age of 81.3(4.3)(SD) years, 52% female and 34% living alone. Only one patient was categorised by the MNA®-SF as malnourished, with an additional 16% classified as at risk of malnutrition. The mean Body Mass Index (BMI) of the at-risk group was significantly lower than the well-nourished group (23.6 ± 0.8 (SEM) vs 27.4 ± 0.3; p=0.0001). However, 34% of the at-risk group had a BMI of 25 or more with only 13% in the underweight category.

CONCLUSION

In this population of older adults attending their general practitioner for an annual health assessment, one in six were identified as being at nutritional risk which is an additional risk factor for a severe health issue. Importantly, one third of the at-risk group had a BMI in the overweight or obese category, highlighting that older people can be at nutritional risk although they may be overweight or obese.

Prevalence and potentially reversible factors associated with anorexia among older nursing home residents: results from the ULISSE project

OBJECTIVE

The principal aims of the present study were to explore the prevalence of anorexia and the factors correlated to anorexia in a large population of older people living in nursing home. Secondary, we evaluated the impact of anorexia on 1-year survival.

METHODS

Data are from baseline evaluation of 1904 participants enrolled in the Un Link Informatico sui Servizi Sanitari Esistenti per l'Anziano study, a project evaluating the quality of care for older persons living in an Italian nursing home. All participants underwent a standardized comprehensive evaluation using the Italian version of the inter Resident Assessment Instrument Minimum Data Set (version 2.0) for Nursing Home. We defined anorexia as the presence of lower food intake. The relationship between covariates and anorexia was estimated by deriving ORs and relative 95% CIs from multiple logistic regression models including anorexia as the dependent variable of interest. Hazard ratios and 95% CIs for mortality by anorexia were calculated.

RESULTS

More than 12% (240 participants) of the study sample suffered from anorexia, as defined by the presence of decreased food intake or the presence of poor appetite. Participants with functional impairment, dementia, behavior problems, chewing problems, renal failure, constipation, and depression, those treated with proton pump inhibitors and opioids had a nearly 2-fold increased risk of anorexia compared with participants not affected by these syndromes. Furthermore, participants with anorexia had a higher risk of death for all causes compared with nonanorexic participants (hazard ratio 2.26, 95% CI: 2.14-2.38).

CONCLUSIONS

The major finding is that potentially reversible causes, such as depression, pharmacologic therapies, and chewing problems, were strongly and independently associated with anorexia among frail older people living in nursing home. Furthermore, anorexia was associated with higher rate of mortality, independently of age and other clinical and functional variables.

Identifying failure to thrive in the long term care setting

INTRODUCTION AND RATIONALE

Geriatric failure to thrive (GFTT) is commonly encountered in the long term care (LTC) setting. This syndrome of unexplained functional decline can be approached in a methodical manner. The updated Minimum Data Set (MDS) 3.0, now implemented in almost all skilled nursing facilities, includes pertinent clinical information that could be used to identify residents who manifest GFTT. A screening tool using data from the MDS 3.0 could be used by LTC providers to evaluate LTC residents.

METHODS

A literature review was completed to identify articles focused on (1) GFTT in the LTC setting and (2) tools to identify GFTT. Common components of GFTT were matched with items collected as part of the MDS 3.0 with a goal to determine its utility as a screening tool to identify GFTT in the LTC setting.

OUTCOMES AND DISCUSSION

The MDS 3.0 includes assessment of numerous components commonly observed in patients with GFTT. By using clinically validated tools, the MDS 3.0 may assist in the recognition of LTC residents with or at risk for GFTT. Once GFTT is recognized, the LTC interdisciplinary team can then identify potentially reversible causes, set goals of care, and develop a comprehensive care plan that may include diagnostic measures, curative interventions, and/or palliative measures individualized to the resident.
