Undernutrition in the European SENECA studies

Nutritional Risk Screening in Cancer Patients: The First Step Toward Better Clinical Outcome

Disease-related malnutrition is highly prevalent among cancer patients, with 40-80% suffering from it during the course of their disease. Malnutrition is associated with numerous negative outcomes such as: longer hospital stays, increased morbidity and mortality rates, delayed wound healing, as well as decreased muscle function, autonomy and quality of life. In cancer patients, malnutrition negatively affects treatment tolerance (including anti-cancer drugs, surgery, chemo- and radiotherapy), increases side effects, causes adverse reactions, treatment interruptions, postoperative complications and higher readmission rates. Conversely, anti-cancer treatments are also known to affect body composition and impair nutritional status. Tailoring early nutritional therapy to patients' needs has been shown to prevent, treat and limit the negative consequences of malnutrition and is likely to improve overall prognosis. As the optimisation of treatment outcomes is top priority and evidence for nutritional therapy is growing, it is increasingly recognized as a significant intervention and an autonomous component of multimodal cancer care. The proactive implementation of nutritional screening and assessment is essential for patients suffering from cancer - given the interaction of clinical, metabolic, pharmacological factors with systemic inflammation; and suppressed appetite with accelerated muscle protein catabolism. At the same time, a nutritional care plan must be established, and adequate individualized nutritional intervention started rapidly. Screening tools for nutritional risk should be validated, standardized, non-invasive, quick and easy-to-use in daily clinical practice. Such tools must be able to identify patients who are already malnourished, as well as those at risk for malnutrition, in order to prevent or treat malnutrition and reduce negative outcomes. This review investigates the predictive value of commonly used screening tools, as well as the sensitivity and specificity of their individual components for improving clinical outcomes in oncologic populations. Healthcare professionals' awareness of malnutrition in cancer patients and the pertinence of early nutritional screening must be raised in order to plan the best possible intervention and follow-up during the patients' ordeal with the disease.

VITAMIN D CONTENT IN POPULATION OF RADIOLOGICALLY CONTAMINATED AREAS IN CHERNIVTSI OBLAST (pilot project)

OBJECTIVE

To study the status of vitamin D in population of Chernivtsi region living on the radioactively contami-nated territories.

MATERIALS AND METHODS

In a cross-sectional study under a pilot project the 180 people aged 19 to 78 years old per-manently residing in 3 regions of Chernivtsi oblast, namely in the village of Kyseliv in Kitsman district, which isattributed to the IIIrd zone of radiololgical contamination due to the Chornobyl catastrophe, as well as in the cityof Chernivtsi and the city of Vyzhnytsia were surveyed in summer. Assay of the 25(OH)D in blood serum was per-formed using the immune chemiluminescence method «ECLIA» on the Elecsys 2010 (Roche Diagnostics, Germany)analyzer using Cobas test systems.

RESULTS

The average level of 25(OH)D in serum was (16.2 ± 0.8) ng/mL, the incidence of vitamin D deficiency was46.9%, and the incidence of vitamin D lack was 53.8%. Severe vitamin D deficiency has been detected in 6 cases inthe village of Kyseliv. At the same time, its share among the surveyed in this region was the highest (11.5%) beingsignificantly different from the proportion of severe deficits in Chernivtsi and Vyzhnytsia. A reliable correlationbetween the body mass index (BMI) and the blood serum level of 25(OH)D was found among persons with BMI of25-29.9 kg/m2. At the same time, the average value of 25(OH)D level among obese subjects (BMI greater than30 kg / m2) was practically the same as in subjects with normal body mass.

CONCLUSIONS

Content of vitamin D was significantly lower among the population of radiologically contaminatedarea vs. the inhabitants of Chernivtsi and Vyzhnytsia. Status of vitamin D among the population of Chernivtsi regionremains far from optimal and requires urgent action for correction and prevention.

Validation of the Photography Method for Nutritional Intake Assessment in Hospitalized Elderly Subjects

OBJECTIVE

The aim of the present study was to validate the photographic indirect method as an accurate and specific tool to assess nutritional intake in a cohort of elderly hospitalized patients.

DESIGN

this is a prospective observational study.

SETTING

hospital (geriatric acute ward and transitional care of IRCCSS AUO San Martino Hospital, Genoa, Italy).

PARTICIPANTS

255 consecutive elderly hospitalized patients.

MEASUREMENTS

assessment of malnutrition by: Mini nutritional assessment (MNA) and abbreviated Comprehensive geriatric assessment (CIRS; Barthel index, SPMSE). The direct method (Gold standard): food dish weight (before lunch) and residual (after lunch) food dish weight and estimation of the percentage of eaten food and of residual food for each dish. The percentages of food intake and residual food were calculated according to the following formula: intake %= initial weight of the dishes- residual food weight)/ initial weight dish x100. The unit of variable was the percentage. The indirect photographic method with extrapolation of the lunch food intake by photographic method confronting initial meal and residual meal (25% quartile food dish estimation).

RESULTS

The results showed a significant correlation between the direct method (weighing residual food) and the indirect photographic method(n=255; r=0.9735; p<0.001) as well as a significant positive correlation between the indirect photographic method and the food caloric estimation calculated by the direct method (n=255; r= 0.6489, p<0.001). Intraclass coefficient (ICC), showed a highly significant degree of agreement between the gold standard and the indirect photographic method (ICC: 0.69; p<0.0001). Additionally, the results showed a good inter rater agreement of the indirect photographic method (kappa-statistic measure of interrater agreement: (Z=13.04; p<0.001); agreement 70.29% e Kappa=0.5965) and a good specificity of the indirect method as it was independent on the single food item.

CONCLUSIONS

The study originally provided the validation of the indirect photographic method for the assessment of nutritional intake in a vast cohort of hospitalized elderly subjects. The present results moved a step forward in the appropriate assessment of nutrition intake in frail elderly, providing an easy to use tool that may be incorporate in routine clinical practice for early and targeted therapeutic interventions.

[Obesity in old age and its importance for functionality and frailty]

In later life a high body mass index (BMI) is associated with the lowest age-related mortality rate. The BMI range used by the World Health Organization (WHO) to classify overweight, a BMI of 25-30 kg/m², can be regarded as normal weight in old age; nevertheless, obesity is associated with an increased risk of disability and of a deterioration in physical functionality, particularly among older age groups. This relationship to obesity has also been established for frailty. For this reason, a reduction in weight may be appropriate under functional aspects if BMI values exceed 30 kg/m²; however, such a decision cannot be made on the basis of an individual BMI alone. The functional status, body composition, comorbidities and, in particular the life perspectives of the patient should also be taken into consideration. If weight loss is intended, it must always be performed under strict medical supervision involving optimized protein intake, a carefully calculated moderate reduction in calories and adequate physical training. In the case of chronically ill elderly patients, weight reduction is not usually appropriate. Restrictive diets of any kind should principally be critically viewed in old age because even temporary inadequate energy intake may lead to accelerated deterioration of muscle and bone structure.

The prevalence and consequences of malnutrition risk in elderly Albanian intensive care unit patients

PURPOSE

Many investigators have reported rising numbers of elderly patients admitted to the intensive care units (ICUs). The aim of the study was to estimate the prevalence of malnutrition risk in the ICU by comparing the prevalence of malnutrition between older adults (aged 65 years and above) and adults (aged 18-64 years), and to examine the negative consequences associated with risk of malnutrition in older adults.

MATERIALS AND METHODS

A prospective cohort study in the ICU of the University Hospital Center of Tirana, Albania, was conducted. Logistic regression analysis was used to analyze the effect of malnutrition risk on the length of ICU stay, the duration of being on the ventilator, the total complications, the infectious complications, and the mortality.

RESULTS

In this study, 963 patients participated, of whom 459 patients (47.7%) were aged ≥65 years. The prevalence of malnutrition risk at the time of ICU admission of the patients aged ≥65 years old was 71.24%. Logistic regression adjusted for confounders showed that malnutrition risk was an independent risk factor of poor clinical outcome for elderly ICU patients, for 1) infections (odds ratio [OR] =4.37; 95% confidence interval [CI]: 2.61-7.31); 2) complications (OR =6.73; 95% CI: 4.26-10.62); 3) mortality (OR =2.68; 95% CI: 1.72-4.18); and 4) ICU length of stay >14 days (OR =5.18, 95% CI: 2.43-11.06).

CONCLUSION

Malnutrition risk is highly prevalent among elderly ICU patients, especially among severely ill patients with malignancy admitted to the emergency ward. ICU elderly patients at malnutrition risk will have higher complication and infection rates, longer duration of ICU stay, and increased mortality. Efforts should be made to implement a variety of nutritional care strategies, to change the nutritional practices not only at ward level, but nationally, according to the best clinical practice and recent guidelines.

Nutritional Assessment and Factors Associated to Malnutrition in Older Adults

Objective: To determine the nutritional status and factors associated to malnutrition in older adults. Method: Data come from the SABE Bogotá study (Health, Well-Being, and Aging), a cross-sectional survey conducted in Bogotá, Colombia, in 2012 in community-dwelling adults aged 60 years and older. Using the Mini Nutritional Assessment (MNA), we evaluated the nutritional status and factors associated to malnutrition in this population with regression models. Results: From the 1,573 older adults interviewed, 4.58% were malnourished and 34.27% were at risk of malnourishment. Factors associated to malnourishment were older age (odds ratio [OR] =1.02, 95% confidence interval [CI] = [1.00, 1.04]), perceived poor health (OR = 1.46, 95% CI = [1.13, 1.88]), comorbidities (OR = 1.16, 95% CI = [1.04, 1.30]), and low calf circumference (OR = 2.63, 95% CI = [1.86, 3.72]). Having dentures, perception of being well-nourished, and higher functionality decreased the odds for malnourishment ( p < .05). Conclusion: The MNA is useful to evaluate factors associated with malnutrition among older adults in Bogotá. Malnutrition is associated with perception of poor health, comorbidities, number of medications, and cognitive impairment.

Screening for malnutrition among nursing home residents - a comparative analysis of the mini nutritional assessment, the nutritional risk screening, and the malnutrition universal screening tool

BACKGROUND

The European Society for Clinical Nutrition and Metabolism (ESPEN) has recommended the Mini Nutritional Assessment (MNA®), the Nutritional Risk Screening 2002 (NRS), and the Malnutrition Universal Screening Tool (MUST) for nutritional screening in various settings and age groups. While in recent years all three tools have been applied to nursing home residents, there is still no consensus on the most appropriate screening tool in this specific setting.

AIM

The present study aims at comparing the MNA, the NRS, and the MUST with regard to applicability, categorization of nutritional status, and predictive value in the nursing home setting.

METHOD

MNA, NRS, and MUST were performed on 200 residents from two municipal nursing homes in Nuremberg, Germany. Follow-up data on infection, hospitalization, and mortality were collected after six and again after twelve months.

RESULTS

Among 200 residents (mean age 85.5 ± 7.8 years) the MNA could be completed in 188 (94.0%) and the NRS and MUST in 198 (99.0%) residents. The prevalence of 'malnutrition' according to the MNA was 15.4%. The prevalence of 'risk of malnutrition' (NRS) and 'high risk of malnutrition' (MUST), respectively, was 8.6% for both tools. The individual categorization of nutritional status showed poor agreement between NRS and MUST on the one hand and MNA on the other. For all tools a significant association between nutritional status and mortality was demonstrated during follow-up as classification in 'malnourished', respectively 'high risk of malnutrition' or 'nutritional risk', was significantly associated with increased hazard ratios. However, the MNA showed the best predictive value for survival among well-nourished residents.

CONCLUSION

The evaluation of nutritional status in nursing home residents by MNA, NRS, and MUST shows significant differences. This observation may be of clinical relevance as nutritional intervention is usually based on screening results. As the items of the MNA reflect particularities of the nursing home population, this tool currently appears to be the most suitable one in this setting.

[Prevalence of malnutrition in Spanish elders: systematic review]

Over the past years, several studies have examined the prevalence of malnutrition. The purpose of the present systematic literature review is to provide an overview of the current knowledge about the nutritional situation of elderly. Based on a literature research, studies with information about the prevalence of malnutrition published between 1995 and 2011 were considered. A total of 43,235 participants from 47 eligible studies were found. According to the Mini Nutritional Assessment, malnutrition was observed in 16.6% (95% confidence interval [95% CI] 0-62); according to anthropometric and biochemical parameters, malnutrition was observed in 21.4% (95% CI 2-77.3) and, when other nutritional indexes were used, malnutrition was observed in 47.3% (95% CI 10.6-94.7). Prevalence rates of malnutrition were highest in studies with a high proportion of patient who were severely disabled, had hip fracture or swallowing problems. It can be concluded that malnutrition is generally widespread and is highly variable, according to parameters used for nutritional assessment, health related problems or the population under study. Future studies should use standardized nutritional assessment tools in order to improve the prognosis of malnutrition in the elderly and achieve better comparability of study results.

Body mass index, life-style, and healthy status in free living elderly people in Menorca Island

OBJECTIVES

To assess the BMI, life-style, and healthy status, and explore relationships between these parameters, among Menorca's free living elderly people.

METHODS

A cross-sectional survey carried out in Menorca Island in 2009. A random sample (n=450) of the elderly population (≥65 years) was interviewed. Anthropometric measurements and a general questionnaire incorporating questions related to socio-demographic and life-style factors and health status were used.

RESULTS

Approximately five per cent of elders were underweight and 60% overweight or obese. Underweight were positively and overweight and obesity negatively affected by age. The prevalence of central obesity, according to the WC cut-off points, was 66.8% in men and 85.1% in women. Low education, socioeconomic status and physical activity were risk factors for malnutrition and overweight/obesity. A possible cognitive impairment was found among elderly persons with BMI<22 kg/m2. A J-shaped association between BMI and hypertension, hypercholesterolemia, heart failure and other CV diseases, a U-shaped relation between BMI and diabetes mellitus, arthritis, and chronic bronchitis, and an inverted J-shape between BMI and gastric ulcer, osteoporosis and bone fractures, cancer, and prostatitis (in men) were found.

CONCLUSIONS

Both low and high BMI are associated with a wide range of prevalent conditions and diseases in Menorca elderly men and women.

Feasibility and reliability of the Mini Nutritional Assessment (MNA) in older adults with intellectual disabilities

OBJECTIVE

Feasibility and reliability of the Mini Nutritional Assessment (MNA) in older adults with intellectual disabilities (ID).

DESIGN

Instrument development.

SETTING

Three care providers for people with ID.

PARTICIPANTS

48 persons aged 50 years and over with borderline to profound ID and their professional caregivers.

MEASUREMENTS

The MNA was performed by means of interviews with participants (N = 12) and caregivers (N = 48) and physical assessments of participants (N = 47). Aspects of feasibility: completion of interview, difficulty of answering interview items, duration of interview and completion of physical assessment. Aspects of reliability: inter-observer reliability between caregivers and between participants and caregivers, test-retest reliability and internal consistency. For inter-observer and test-retest reliability, intraclass correlation coefficients (ICC) were calculated, and for internal consistency Chronbach's alpha.

RESULTS

All participants and caregivers completed the interview part. For 7 out of 12 personally interviewed participants and none of the caregivers, at least 3 out of 15 questions were difficult to answer. Mean duration of the interview was 7 minutes in participants and 4 minutes in caregivers. Physical assessment was successfully performed in 40 participants (85.1%). In the remaining 7 participants (14.9%) missing values were retrieved from the medical records. ICCs (95% confidence interval) for test-retest and inter-observer reliability between caregivers were good, 0.85 (0.72 - 0.92) and 0.86 (0.74 - 0.92) respectively, but ICC for inter-observer reliability between caregivers and persons with ID was low, 0.03 (-0.51 - 0.59). Internal consistency was 0.61.

CONCLUSION

The MNA is feasible and reliable for older people with ID. Interview data can be reliably obtained through caregivers, but not through people with ID.

Comparison of three screening tools for nutritional status assessment of the elderly in their homes

BACKGROUND

The prevailing recommendation for the elderly is to live in their own homes as long as conditions allow. With this emphasis on the natural living environment, it is imperative to closely monitor both the general health and nutritional needs of the elderly in community settings.

AIM

The aim of the study was to compare three nutritional status screening and evaluation tools of the elderly in their homes.

METHODS

Testing of measuring instruments, MNA, SGA, and MUST took place in the homes of 120 seniors in selected areas of the Czech and Slovak Republics. The study included 120 seniors. For testing of the relationships and dependencies, Pearson's correlation coefficient, t and Fisher tests were used. The level of statistical significance was α = 0.05.

RESULTS

All tests were to a large degree correlated (p(MNA) = 0.0049; p(MUST) = -0.537; p(SGA) = -0.578) with the body mass index of the seniors. Simultaneously, it was confirmed that the tools for assessing nutritional status in the study showed significant differences regarding the classification of patients at risk of malnutrition and/or malnourished patients.

CONCLUSIONS

Based on the findings, we conclude that MNA appeared to be a more appropriate tool for nutritional assessment of the elderly living in their homes. SGA and MUST provided rather subjective evaluation of the nutritional status and did not furnish an in-depth categorization of malnutrition.

Impact of restrictive diets on the risk of undernutrition in a free-living elderly population

BACKGROUND & AIMS

Elderly subjects are at risk for undernutrition. Restrictive diets may increase this risk. The aim was to evaluate the impact of restrictive diets on undernutrition and its risk in free-living elderly.

METHODS

Ambulatory patients over age 75 and under a restrictive diet (low salt, low cholesterol, diabetic) were included prospectively, along with age- and gender-matched controls. Weight and height were measured, and the short-form of the Mini Nutritional Assessment was scored. Groups were compared to determine variables associated with a low MNA-SF(®).

RESULTS

95 patients in the diet group (62 F, 33 M, 80 ± 4 y) and 95 controls (57 F, 38 M, 82 ± 5 y) were included. Restrictive diets (low salt n = 33, diabetic n = 19, low cholesterol n = 15, combination n = 27) had been followed since 11.0 ± 5.9 years. Using the cut-off of 12 for MNA-SF(®), 44 patients in the diet group were at risk vs. 22 among controls (P < 0.001). In multivariate analysis, a restrictive diet increased the probability of having an MNA-SF(®) < 12 (OR = 3.6, (95%)CI = 1.8-7.2, P < .001).

CONCLUSIONS

Restrictive diets in patients over 75 increase the risk of undernutrition. On an individual level, these diets may need reassessment. Society guidelines should promote specific recommendations for the elderly.

Body mass index and disease burden in elderly men and women: the Tromsø Study

Chronic health problems may be related to body mass index (BMI, kg/m(2)), but this has been best documented in overweight and obese adults. The primary objective of this study was to identify factors associated with different categories of BMI in elderly men and women from the general population, also including the lower categories of BMI. In a cross-sectional population survey from the municipality of Tromsø, Norway we analyzed associations between BMI and a wide range of chronic disease conditions, lifestyle and socioeconomic factors. BMI was categorized into six groups (<20, 20.0-22.4, 22.5-24.9, 25.0-27.4, 27.5-29.9, > or =30.0 kg/m(2)). The study included 4,259 men and women aged 65 years and older from the general population. We found low relative weight (BMI < 20 kg/m(2)) to be associated with increasing prevalence of mental distress, hip fracture, smoking and low handgrip strength. A U-shaped relation to BMI was found for asthma and chronic bronchitis, poor current health and low physical activity. The higher categories of BMI were associated with low education level, a difficult economical situation, diabetes mellitus and ischemic heart disease. These results demonstrate that both low and high BMI are associated with a wide range of prevalent conditions and diseases in elderly men and women. For the clinician the findings emphasize the importance of nutritional assessment as part of the medical evaluation of elderly patients.

[Underweight in elderly persons. A retrospective analysis of 3821 forensic autopsies in Hamburg]

AIM AND METHOD

Based on the systematic analyses of a 10-year period at the Institute of Forensic Medicine at the University Clinic Hamburg-Eppendorf, the frequency of underweight in elderly persons at their time of death was retrospectively calculated. Body mass index (BMI) values <20 kg/m(2) were taken as indicative of underweight and the data of 1,551 women and 2,270 men, mean age 69 years (51-101 years) were analyzed.

RESULTS

The prevalence of underweight was 15.4%. Low BMI values were more frequent in women than men (18.8 vs. 13.1%) and more frequent in persons needing professional nursing care at the time of death (28.9%). Underweight increased for the age range 70-79 from about 15% to over 38% for those 90 years and older at the time of death. Pressure sores were documented in 1.8% of cases. Persons in need of professional nursing care more often had pressure sores at their time of death. Furthermore, pressure sores were observed more often in underweight elderly in need of professional nursing care.

CONCLUSION

Underweight at the time of death is observed more often in the very old. This is associated with the need for professional nursing care and also the occurrence of pressure sores. Less than 5% of persons with tumors were included. The results underscore the need of early detection of people at risk of malnutrition when growing older.

Prevalence of malnutrition and associated metabolic risk factors for cardiovascular disease in older adults from Northwest Mexico

This cross-sectional study assessed the prevalence of malnutrition and several metabolic risk factors for cardiovascular disease in 287 apparently healthy older adults from Northwest Mexico. Also, the impact of overweight and obesity on metabolic risk factors was assessed. Nutritional status was determined using serum albumin levels and anthropometry. Vitamin status was also assessed. Metabolic risk factors for cardiovascular disease were evaluated. The prevalence of undernutrition was 15.3%. Also, vitamin E deficiency was common (18%). On the contrary, 44.9% of men and women were in overweight and 24% were obese. A 50.9% of the older adults had hypertension, 52.6% hypercholesterolemia (HC), 38.3% hypertriglyceridemia (HTG), 26.1% impaired fasting glucose and 26.1% impaired glucose tolerance (IGT). HC and low-density-lipoprotein-cholesterol (LDL-C) were significantly more prevalent in women than in men. Mean adjusted values of fasting glucose, high-density-lipoprotein-cholesterol (HDL-C), total cholesterol (TC)/HDL-C ratio > or = 5, triglycerides (TG) and diastolic blood pressure (DBP) were significantly higher in subjects with body mass index (BMI) > or = 25.0 kg/m(2). Undernutrition, obesity and vitamin E deficiency, as well as several metabolic risk factors for cardiovascular disease coexisted in this studied group. Overweight and obesity were the most prevalent findings. BMI > or = 25 kg/m(2) was the common factor explaining most of the metabolic abnormalities. However, due to the sample size and the design of the study, the results must be seen with caution and cannot be generalized.

[Significance and diagnosis of malnutrition in the elderly]

In certain high-risk groups like geriatric hospital patients and nursing home inhabitants malnutrition has a high prevalence and is highly relevant for morbidity and mortality in these populations. The diagnosis of malnutrition in the elderly can be achieved by simple parameters like loss of weight, BMI and oral intake. The available screening and assessment instruments like Mini Nutritional Assessment (MNA) and Nutritional Risk Screening (NRS 2002) aim at the standardization of the diagnosis and early recognition of malnutrition. While the MNA seems to be more appropriate for the community-dwelling elderly, the NRS 2002 offers advantages for the hospital setting. The dissimilarity of the two instruments makes the comparison of study populations difficult. Both the results of the MNA and those of the NRS 2002 are unsuitable as follow-up parameters and inappropriate for the evaluation of nutritional intervention. There is still a strong need for studies on the diagnosis and therapy of malnutrition in the elderly, especially in the nursing home setting. For scientific purposes a standardization of the instruments used for the diagnosis of malnutrition and for the evaluation of the study results is essential. The Minimum Data Set may be a first step in the right direction.

Unintended weight loss in the elderly living at home: the aged in Home Care Project (AdHOC)

OBJECTIVE

To describe associations between unintended weight loss (UWL) and characteristics of nutritional status.

DESIGN

A comparative cross-sectional assessment study at 11 sites in Europe. The target population was a stratified random sample of 4,455 recipients of home care (405 in each random sample from 11 urban areas) aged 65 years and older.

MEASUREMENTS

the Resident Assessment Instrument for Home Care, version 2.0. Epidemiological and medical characteristics of clients and service utilisation were recorded in a standardized, comparative manner. UWL was defined as information of 5% or more weight loss in the last 30 days (or 10% or more in the last 180 days).

RESULTS

The final sample consisted of 4,010 persons; 74% were female. The mean ages were 80.9 +/- 7.5 years (males) and 82.8 +/- 7.3 years (females). No associations were found between single diagnoses and UWL, except for cancer. Cancer patients were excluded from further analyses. Persons with a Cognitive Performance Scale value (CPS) superior 3 (impaired) had increased risk of UWL (OR = 2.0) compared with those scoring inferior or egal 3 (less impaired). Only in the oldest group did we find a significant association between UWL and reduction in ADL and IADL functions, comparing those who scored 3 or less with those who scored more than 3 (disabled). A binary logistic regression model explained 26% of UWL: less than one meal/day, reduced appetite, malnutrition, reduced social activity, experiencing a flare-up of a recurrent or chronic problem, and hospitalisation were important indicators.

CONCLUSION

We recommend a regular comprehensive assessment in home care to identify clients with potential risk factors for weight loss and malnutrition, in particular those discharged from hospital, and those with physical dependency or cognitive problems. This study may provide incentives to create tailored preventive strategies.

Characteristics of undernourished older medical patients and the identification of predictors for undernutrition status

Background

Undernutrition among older people is a continuing source of concern, particularly among acutely hospitalized patients. The purpose of the current study is to compare malnourished elderly patients with those at nutritional risk and identify factors contributing to the variability between the groups.

Methods

The study was carried out at the Soroka University Medical Center in the south of Israel. From September 2003 through December 2004, all patients 65 years-of-age or older admitted to any of the internal medicine departments, were screened within 72 hours of admission to determine nutritional status using the short version of the Mini Nutritional Assessment (MNA-SF). Patients at nutritional risk were entered the study and were divided into malnourished or 'at risk' based on the full version of the MNA. Data regarding medical, nutritional, functional, and emotional status were obtained by trained interviewers.

Results

Two hundred fifty-nine elderly patients, 43.6% men, participated in the study; 18.5% were identified as malnourished and 81.5% were at risk for malnutrition according to the MNA. The malnourished group was less educated, had a higher depression score and lower cognitive and physical functioning. Higher prevalence of chewing problems, nausea, and vomiting was detected among malnourished patients. There was no difference between the groups in health status indicators except for subjective health evaluation which was poorer among the malnourished group. Lower dietary score indicating lower intake of vegetables fruits and fluid, poor appetite and difficulties in eating distinguished between malnourished and at-risk populations with the highest sensitivity and specificity as compare with the anthropometric, global, and self-assessment of nutritional status parts of the MNA. In a multivariate analysis, lower cognitive function, education <12 years and chewing problems were all risk factors for malnutrition.

Conclusion

Our study indicates that low food consumption as well as poor appetite and chewing problems are associated with the development of malnutrition. Given the critical importance of nutritional status in the hospitalized elderly, further intervention trials are required to determine the best intervention strategies to overcome these problems.

Nutritional situation of elderly nursing home residents

Malnutrition in institutionalized elderly is of individual and public concern since it negatively affects health outcome and quality of life and is often preventable. Over the past years several studies have examined the prevalence of malnutrition in institutionalized elderly and reported greatly diverse results. The purpose of the present literature review is to give an overview of the current knowledge about the nutritional situation of institutionalized elderly having specific regard to the prevalence of protein-energy malnutrition and nutrition-related problems. Based on a literature search and additional articles from the files of the authors, observational studies with relatively unselected populations reporting figures for the prevalence of malnutrition and/or the prevalence of nutrition-related problems (e. g. poor appetite, chewing or swallowing problems, eating dependency or poor intake) and published between 1990 and 2006 were considered. Relevant information was extracted and compiled. A total of 42 eligible studies with 41 to 6832 participants were found. BMI was the most frequently used parameter for nutritional assessment with mean values mostly between 21 and 24 kg/m(2). Eight studies applied a cut-off value of 20 kg/m(2) and reported between 10% and 50% low values. Weight loss was reported in 7 studies with prevalence rates between 5 and 41%, reduced serum albumin (< 35 g/L) in 10 studies with prevalence rates between 0 and 50%. According to the MNA (12 studies) malnutrition was observed in 2 to 38% and a risk of malnutrition in 37 to 62%. Nutritional problems were reported in 17 studies, again with great variability between the studies. In physically and mentally capable study populations malnutrition was relatively unfrequent. Prevalence rates were highest in studies with great proportions of disabled and severely impaired residents. It can be concluded that malnutrition is generally widespread in institutionalized elderly. Prevalence rates vary according to the parameters and cut-off values used for nutritional assessment and according to the population under study. Future studies should carefully characterize their participants and use standardized nutritional assessment tools in order to achieve better comparability of study results as up to now.

Nutritional risk and low weight in community-living older adults: a review of the literature (1995-2005)

Although many studies have examined weight loss and low weight in institutionalized persons, there has been little research exploring the community-living older adult's nutritional risk. The purpose of this literature review (1995-2005) is to describe our current understanding of nutritional risk and low weight in community-living older adults 65 years old and older. Computerized database searches and footnote reviews were used to find published studies on nutritional risk and low weight. Twenty-two research articles are reviewed and summarized. Each study was reviewed according to preset criteria.

Gender differences in factors associated with nutritional status of older medical patients

OBJECTIVES

To evaluate gender differences in nutritional risk of older people admitted to an acute-care general medical department, and identify gender-specific risk factors.

DESIGN

Cross-sectional study.

SETTING

Internal Medicine Department in an acute care, university-affiliated hospital in southern Israel.

SUBJECTS

204 cognitively intact patients aged 65 and over, admitted during a 12-month period to a general medical department.

MEASURES OF OUTCOME

Evaluation included demographic and clinical data consisting of the sum of medical conditions and of prescribed medications, evaluation of nutritional status, cognitive status, depression assessment and functional ability. Statistical analyses were conducted to evaluate the gender specific risk factors for under-nutrition.

RESULTS

32.5% of the men and 48.1% of the women admitted to an internal medicine department were at risk for under-nutrition. Those at nutritional risk had a higher rate of depression, lower cognitive and physical ability, poorer reported health status and more diagnosed diseases. Nutritional risk for men was associated with higher depression score, longer hospitalization, and poor appetite. For women, nutritional risk was associated with lower functional status and more diagnosed diseases. In a multivariate analysis, being a female increased the risk of under-nutrition by 3.3 fold.

CONCLUSION

Risk of under-nutrition is prevalent among older in-patients and is gender-related. Female inpatients are at markedly increased risk for under-nutrition. The mechanism of the gender discrepancy in factors related to nutritional deterioration is complex and poorly understood.

Estimating renal function in older people: a comparison of three formulas

BACKGROUND

Estimation of the glomerular filtration rate (GFR) at the bedside is important because renal insufficiency is related to increased mortality and morbidity. A discrepancy between the Cockroft-Gault (CG) and the Modification of Diet in Renal Disease (MDRD) formulas has been observed in older people.

OBJECTIVE

To compare the GFR of inpatients aged 65 or older estimated using the CG and two of the MDRD formulas.

SETTING

Acute care geriatrics and internal medicine wards.

SUBJECTS AND METHODS

Data come from the Gruppo Italiano di Farmacovigilanza nell'Anziano (GIFA). To quantify the agreement between the formulas, we used the 95% limits of agreement, the kappa statistic and a graphic approach to evaluate the influence of potential confounders on the magnitude of the difference in the GFR estimates.

RESULTS

We studied 7,747 persons [51.1% women, mean age 77.8 (SD 7.2)]. The mean GFR estimated using the CG, MDRD1 and MDRD2 formulas was 51.2 ml/min (21.3), 54.9 ml/min (19.8) and 64.7 ml/min (24.2), respectively. At the individual level, the MDRD formulas can yield estimates that differ by more than 50% compared with the CG formula. The formulas showed a moderate agreement in diagnosing moderate renal insufficiency and a fair agreement in diagnosing severe renal insufficiency. The magnitude of the difference in GFR estimates was influenced by age and weight.

CONCLUSIONS

The CG and MDRD formulas have a good average agreement, but at the individual level, they can give estimates that differ substantially, and cannot be used interchangeably to measure renal function in elderly people.

Comparison of the Mini Nutritional Assessment, Subjective Global Assessment, and Nutritional Risk Screening (NRS 2002) for nutritional screening and assessment in geriatric hospital patients

The Mini Nutritional Assessment (MNA), the Subjective Global Assessment (SGA) and the Nutritional Risk Screening (NRS) are screening and assessment tools aimed at detecting malnourished individuals and those at risk for malnutrition. In our study we tested their applicability in geriatric hospital patients and compared the results of the three tools. We examined prospectively all patients of two acute geriatric wards by the MNA, the SGA and the NRS. 121 patients were included in the study. The MNA could be completed in 66.1% of all patients, the SGA in 99.2% and the NRS in 98.3%. There was a significant association of all three tools with the BMI (p<0.01). With regard to serum albumin and to length of hospital stay (p<0.05), only a significant association could be shown for the MNA (p<0.05). Although the categories of the results were not completely identical for the three tools there were more patients at risk or malnourished according to the MNA (70%) than according to the SGA (45%) or the NRS (40.3%). The direct comparison of the NRS with the MNA and the SGA demonstrated significant differences, especially for the latter (p<0.001). In a relevant percentage of those tested, MNA, SGA, and NRS identify different individuals as malnourished or at risk for malnutrition. Because of its association with relevant prognostic parameters, the MNA is still the first choice for geriatric hospital patients. For those patients to whom the MNA cannot be applied, the NRS is recommended.

Feeding and hydration issues for older adults with dementia

All cultures dictate the need to feed the hungry and create rituals for almost every life passage around the consumption of food and beverage. Yet, in old age and among those who cannot advocate for themselves, mealtime is medicalized and demoted to an insignificant event without dignity or regard for individualized needs. Attention must be paid to not only what people eat, but how they eat, and how they are supported in that process. Kayser-Jones summarized the extensive findings of several ethnographic studies in nursing homes by noting the multi-factorial issues involved in delivering excellent care to all residents, especially those lacking an advocate. Her findings exposed how lack of staff education, inadequate staffing and supervision, disregard for personal and cultural preferences, lack of assessment for comorbid health problems, intake of food and fluids, dysphagia, and oral health problems all contributed to malnutrition and dehydration among the residents studied. This seminal set of studies, along with Dr. Kayser-Jones' testimony in US Congressional hearings directly affected the design of federal regulatory protocols to address malnutrition and dehydration. In an attempt to increase the number of staff available to assist at meals, the Centers for Medicare and Medicaid issued a change in regulations on Sept. 26, 2003, allowing reimbursement for staff trained for a total of 8 hours to act as feeding assistants. This change is intended to, "provide more residents with help in eating and drinking and reduce the incidence of unplanned weight loss and dehydration". Although seen as answering some of the staffing ratio issues at meal times,this rule change has been criticized for not addressing the complexities of resident needs at meal times. Although offering food and fluid is time-consuming and requires special knowledge of physiological changes and empathy for persons whose behavior might be objectionable at times, it may be one of the few times during the day that the individual with dementia receives normalized social interaction. Thus, as in the care of all vulnerable persons with dementia, whether at home or in an institution, perhaps the greatest challenge and need is for nurses and other caregivers to provide a social environment that promotes individual dignity and comfort.
