The mini nutritional assessment (MNA) and its use in grading the nutritional state of elderly patients

The Mini Nutritional Assessment (MNA) has recently been designed and validated to provide a single, rapid assessment of nutritional status in elderly patients in outpatient clinics, hospitals, and nursing homes. It has been translated into several languages and validated in many clinics around the world. The MNA test is composed of simple measurements and brief questions that can be completed in about 10 min. Discriminant analysis was used to compare the findings of the MNA with the nutritional status determined by physicians, using the standard extensive nutritional assessment including complete anthropometric, clinical biochemistry, and dietary parameters. The sum of the MNA score distinguishes between elderly patients with: 1) adequate nutritional status, MNA > or = 24; 2) protein-calorie malnutrition, MNA < 17; 3) at risk of malnutrition, MNA between 17 and 23.5. With this scoring, sensitivity was found to be 96%, specificity 98%, and predictive value 97%. The MNA scale was also found to be predictive of mortality and hospital cost. Most important it is possible to identify people at risk for malnutrition, scores between 17 and 23.5, before severe changes in weight or albumin levels occur. These individuals are more likely to have a decrease in caloric intake that can be easily corrected by nutritional intervention.

Sarcopenia, Calf Circumference, and Physical Function of Elderly Women: A Cross-Sectional Study

OBJECTIVES: To determine whether calf circumference (CC), related to appendicular skeletal muscle mass, can be used as a measure of sarcopenia and is related to physical function.

COGNITIVE FRAILTY: RATIONAL AND DEFINITION FROM AN (I.A.N.A./I.A.G.G.) INTERNATIONAL CONSENSUS GROUP

The frailty syndrome has recently attracted attention of the scientific community and public health organizations as precursor and contributor of age-related conditions (particularly disability) in older persons. In parallel, dementia and cognitive disorders also represent major healthcare and social priorities. Although physical frailty and cognitive impairment have shown to be related in epidemiological studies, their pathophysiological mechanisms have been usually studied separately. An International Consensus Group on “Cognitive Frailty” was organized by the International Academy on Nutrition and Aging (I.A.N.A) and the International Association of Gerontology and Geriatrics (I.A.G.G) on April 16th, 2013 in Toulouse (France). The present report describes the results of the Consensus Group and provides the first definition of a “Cognitive Frailty” condition in older adults. Specific aim of this approach was to facilitate the design of future personalized preventive interventions in older persons. Finally, the Group discussed the use of multidomain interventions focused on the physical, nutritional, cognitive and psychological domains for improving the well-being and quality of life in the elderly. The consensus panel proposed the identification of the so-called “cognitive frailty” as an heterogeneous clinical manifestation characterized by the simultaneous presence of both physical frailty and cognitive impairment. In particular, the key factors defining such a condition include: 1) presence of physical frailty and cognitive impairment (CDR=0.5); and 2) exclusion of concurrent AD dementia or other dementias. Under different circumstances, cognitive frailty may represent a precursor of neurodegenerative processes. A potential for reversibility may also characterize this entity. A psychological component of the condition is evident and concurs at increasing the vulnerability of the individual to stressors.

Is There a Relationship Between Fat‐Free Soft Tissue Mass and Low Cognitive Function? Results From a Study of 7,105 Women

OBJECTIVES: To test the hypothesis that low fat‐free soft tissue mass and cognitive impairment are independently associated.

Nutrition assessment in the elderly.

The prevalence of malnutrition, which is relatively low in free-living elderly persons (5-10%), is considerably higher (30-60%) in hospitalized or institutionalized elderly persons. As a result, nutritional assessment should be part of routine clinical practice in elderly patients who are frail, sick or hospitalized. A comprehensive screening tool for assessment of nutritional status is needed that is clinically relevant and cost-effective to perform. A number of simple and rapid tests for detecting or diagnosing malnutrition in the elderly have recently been developed. If malnutrition is suggested by such screening tests, then they should be supplemented by conventional nutritional assessment before treatment is planned.

Frailty, osteoporosis and hip fracture: Causes, consequences and therapeutic perspectives

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.

Description of 1,108 older patients referred by their physician to the "Geriatric Frailty Clinic (G.F.C) for Assessment of Frailty and Prevention of Disability" at the gerontopole.

IntroductionFrailty is considered as an early stage of disability which, differently from disability, is still amenable for preventive interventions and is reversible. In 2011, the “Geriatric Frailty Clinic (G.F.C) for Assessment of Frailty and Prevention of Disability” was created in Toulouse, France, in association with the University Department of General Medicine and the Midi-Pyrenees Regional Health Authority. This structure aims to support the comprehensive and multidisciplinary assessment of frail older persons, to identify the specific causes of frailty and to design a personalized preventive plan of intervention against disability. In the present paper, we describe the G.F.C structure, organization, details of the global evaluation and preventive interventions against disability, and provide the main characteristics of the first 1,108 patients evaluated during the first two years of operation.MethodsPersons aged 65 years and older, considered as frail by their physician (general practitioner, geriatrician or specialist) in the Toulouse area, are invited to undergo a multidisciplinary evaluation at the G.F.C. Here, the individual is assessed in order to detect the potential causes for frailty and/or disability. At the end of the comprehensive evaluation, the team members propose to the patient (in agreement with the general practitioner) a Personalized Prevention Plan (PPP) specifically tailored to his/her needs and resources. The G.F.C also provides the patient’s follow-up in close connection with family physicians.ResultsMean age of our population was 82.9 6.1 years. Most patients were women (n=686, 61.9%). According to the Fried criteria, 423 patients (39.1%) were pre-frail, and 590 (54.5%) frail. Mean ADL (Activities of Daily Living) score was 5.5±1.0. Consistently, IADL (Instrumental ADL) showed a mean score of 5.6 2.4. The mean gait speed was 0.78±0.27 and 25.6% (272) of patients had a SPPB (Short Physical Performance Battery) score equal to or higher than 10. Dementia was observed in 14.9% (111) of the G.F.C population according to the CDR scale (CDR ≥2). Eight percent (84) presented an objective state of protein-energy malnutrition with MNA (Mini Nutritional Assessment) score < 17 and 39.5% (414) were at risk of malnutrition (MNA=17–23.5). Concerning PPP, for 54.6% (603) of patients, we found at least one medical condition which needed a new intervention and for 32.8% (362) substantial therapeutic changes were recommended. A nutritional intervention was proposed for 61.8% (683) of patients, a physical activity intervention for 56.7% (624) and a social intervention for 25.7% (284). At the time of analysis, a one-year reassessment had been carried out for 139 (26.7%) of patients.ConclusionsThe G.F.C was developed to move geriatric medicine to frailty, an earlier stage of disability still reversible. Its particularity is that it is intended for a single target population that really needs preventive measures: the frail elderly screened by physicians. The screening undergone by physicians was really effective because 93.6% of the subjects who referred to this structure were frail or pre-frail according to Fried’s classification and needed different medical interventions. The creation of units like the G.F.C, specialized in evaluation, management and prevention of disability in frail population, could be an interesting option to support general practitioners, promote the quality of life of older people and increase life expectancy without disability.

Body composition in French women 75+ years of age: the EPIDOS study.

BACKGROUND There are presently no published data on age-related changes in body composition in French individuals older than 65 or 80 years. This paper presents a cross-sectional study of 7518 community-residing French women older than 75 years. METHODS We examined age differences changes in body composition and anthropometry between age groups (76-80, 81-85, and 86-95 years of age). Whole body composition was estimated using a dual energy X-ray absorptiometry (DXA) scanner. Measurements of appendicular skeletal muscle (ASM) mass and sarcopenia were performed for a subsample of 1321 women. RESULTS Significant age differences exist in total fat mass and total bone mineral content in elderly women between 76 and 95 years of age. There was also a significant decreased in fat free soft tissue mass from 76 to 85. The decline in fat free mass may be reduced over 85 years of age. The prevalence of low muscle mass, or sarcopenia, increased with age from 8.9 in 76-80 to 10.9% in 86-95 age group, but the difference was not statistically significant. CONCLUSIONS Interventional programs developed to prevent or reduce sarcopenia would have a better influence on population under 85 years, i.e. when the decline in ASM mass is the most severe. Others longitudinal studies could be performed to confirm our results.

Nutritional status is associated with disease progression in very mild Alzheimer disease.

The objective of this study is to identify, in a sample of very mild Alzheimer disease (AD) patients, factors associated with disease progression. The authors followed 160 AD patients from a multicenter cohort with a Clinical Dementia Rating (CDR) of 0.5, corresponding to very mild AD but with impairment insufficient to be classified as dementia. Patients with disease progression were defined as those with CDR≥1 at 1 year; those with no progression (stable) remained at CDR 0.5. The baseline characteristics of these 2 groups of patients were compared in search of predictors of progression. After a 1-year follow-up, 84 (52.5%) of the patients remained stable, CDR 0.5; 76 (47.5%) progressed to a CDR score ≥1. A baseline lower nutritional status assessed by the Mini Nutritional Assessment [odds ratio 0.80, 95% confidence interval (0.68-0.94), P=0.007] and a lower cognitive performance on the Alzheimer Disease Assessment Scale [odds ratio 1.22, 95% confidence interval (1.07-1.39), P=0.003] were found as predictors of progression. The results suggest that clinical assessment of nutritional status, along with cognitive data, may help detect patients at risk of progression in very early AD. Nutritional assessment should therefore form part of clinical evaluation of patients with AD at an early stage of the disease.
