Diagnostic criteria for malnutrition - An ESPEN Consensus Statement

Trajectories of functional decline in older adults with neuropsychiatric and cardiovascular multimorbidity: A Swedish cohort study

BACKGROUND

Functional decline is a strong health determinant in older adults, and chronic diseases play a major role in this age-related phenomenon. In this study, we explored possible clinical pathways underlying functional heterogeneity in older adults by quantifying the impact of cardiovascular (CV) and neuropsychiatric (NP) chronic diseases and their co-occurrence on trajectories of functional decline.

METHODS AND FINDINGS

We studied 2,385 people ≥60 years (range 60-101 years) participating in the Swedish National study of Aging and Care in Kungsholmen (SNAC-K). Participants underwent clinical examination at baseline (2001-2004) and every 3 or 6 years for up to 9 years. We grouped participants on the basis of 7 mutually exclusive clinical patterns of 0, 1, or more CV and NP diseases and their co-occurrence, from a group without any CV and NP disease to a group characterised by the presence of CV or NP multimorbidity, accompanied by at least 1 other CV or NP disorder. The group with no CV and/or NP diseases served as the reference group. Functional decline was estimated over 9 years of follow-up by measuring mobility (walking speed, m/s) and independence (ability to carry out six activities of daily living [ADL]). Mixed-effect linear regression models were used (1) to explore the individual-level prognostic predictivity of the different CV and NP clinical patterns at baseline and (2) to quantify the association between the clinical patterns and functional decline at the group level by entering the clinical patterns as time-varying measures. During the 9-year follow-up, participants with multiple CV and NP diseases had the steepest decline in walking speed (up to 0.7 m/s; p < 0.001) and ADL independence (up to three impairments in ADL, p < 0.001) (reference group: participants without any CV and NP disease). When the clinical patterns were analyzed as time varying, isolated CV multimorbidity impacted only walking speed (β -0.1; p < 0.001). Conversely, all the clinical patterns that included at least 1 NP disease were significantly associated with decline in both walking speed (β -0.21--0.08; p < 0.001) and ADL independence (β -0.27--0.06; p < 0.05). Groups with the most complex clinical patterns had 5%-20% lower functioning at follow-up than the reference group. Key limitations of the study include that we did not take into account the specific weight of single diseases and their severity and that the exclusion of participants with less than 2 assessments may have led to an underestimation of the tested associations.

CONCLUSIONS

In older adults, different patterns of CV and NP morbidity lead to different trajectories of functional decline over time, a finding that explains part of the heterogeneity observed in older adults' functionality. NP diseases, alone or in association, are prevalent and major determinants of functional decline, whereas isolated CV multimorbidity is associated only with declines in mobility.

Comparing Western and Eastern criteria for sarcopenia and their association with survival in patients with pancreatic cancer

BACKGROUND & AIMS

Sarcopenia and cachexia are associated with pancreatic cancer and serve as important adverse prognostic factors. Body composition can be analyzed by routine computed tomography (CT) for cancer staging and has been used to study many types of cancer. The CT measurements are robust, but the diagnostic criteria for sarcopenia vary among different studies. Age, sex and race are important factors that affect muscle and fat masses. This study aimed to analyze the effect of different sarcopenia diagnostic criteria on the prognosis of patients with pancreatic cancer.

METHODS

Patients with newly diagnosed pancreatic cancer at National Taiwan University Hospital between October 2013 and October 2016 were retrospectively reviewed in this study. Body composition was assessed using cross-sectional CT images to calculate the total skeletal muscle (TSM) index. The concordance and interobserver variability of the TSM measurements were evaluated using both the Western criteria and the Eastern criteria. Kaplan-Meier analyses and the Cox proportional hazard ratio with two different diagnostic criteria for sarcopenia were used to compare the effect on overall survival (OS).

RESULTS

A total of 146 patients with pancreatic cancer were enrolled. The TSM index measured by the Western institute was highly correlated with that measured by the Eastern institute (r = 0.953, p < 0.001). The prevalence of sarcopenia in the patient group at baseline was 66.4% (97/146) by the Western criteria and 11.0% (16/146) by the Eastern criteria, and only low agreement was found between the Western and Eastern criteria (Kappa value = 0.028, p = 0.149). Patients who were sarcopenic by the Western criteria showed no significant difference in OS versus those who were not sarcopenic (p = 0.807). However, patients who were sarcopenic by the Eastern criteria showed a significant difference in OS versus those who were not sarcopenic in a univariate analysis (p = 0.008) and multivariate analysis after adjustment for AJCC stage (p = 0.014).

CONCLUSIONS

Our study demonstrates that different diagnostic criteria may result in different diagnoses and that sarcopenia is an important poor prognostic factor for pancreatic cancer when appropriate diagnostic criteria are selected.

Prevalence and Risk of Protein-Energy Wasting Assessed by Subjective Global Assessment in Older Adults With Advanced Chronic Kidney Disease: Results From the EQUAL Study

OBJECTIVES

Prevalence and risk factors for protein-energy wasting (PEW) are poorly studied in the nondialysis, older population with advanced chronic kidney disease (CKD). Our aim was to evaluate the prevalence of PEW in advanced stage CKD patients aged greater than 65 years. Furthermore, we aimed to describe risk factors for PEW in the overall study population and among obese individuals.

DESIGN

Prospective observational cohort study.

METHODS

The EQUAL study, a European Quality Study on treatment in advanced chronic kidney disease, is a multicenter prospective observational cohort study in six European countries. We included patients aged ≥65 years with incident glomerular filtration rate <20mL/min/1.73m² not on dialysis attending nephrology care. PEW was assessed by 7-point Subjective Global Assessment (7-p SGA).

RESULTS

In general, the study cohort (n = 1,334) was overweight (mean body mass index [BMI] 28.4 kg/m²). The majority of the patients had a normal nutritional status (SGA 6-7), 26% had moderate PEW (SGA 3-5), and less than 1% had severe PEW (SGA 1-2). Muscle wasting and loss of fat tissue were the most frequent alterations according to the SGA subscales, especially in those aged >80 years. The prevalence of PEW was higher among women, increased with age, and was higher in those with depression/dementia. PEW was the most common in those with underweight (BMI <22 kg/m²), 55% or normal weight (BMI 22-25 kg/m²), 40%. In obese individuals (BMI >30 kg/m²), 25% were diagnosed with protein wasting. Risk factors for SGA ≤5 in obese people were similar to those for the overall study population.

CONCLUSION

This European multicenter study shows that the prevalence of PEW is high in patients with advanced CKD aged >65 years. The risk of PEW increases substantially with age and is commonly characterized by muscle wasting. Our study suggests that focus on nutrition should start early in the follow-up of older adults with CKD.

Prospective associations of poor diet quality with long-term incidence of protein-energy malnutrition in community-dwelling older adults: the Health, Aging, and Body Composition (Health ABC) Study

Background

Protein-energy malnutrition (PEM) is a major problem in older adults. Whether poor diet quality is an indicator for the long-term development of PEM is unknown.

Objective

The aim was to determine whether poor diet quality is associated with the incidence of PEM in community-dwelling older adults.

Design

We used data on 2234 US community-dwelling older adults aged 70-79 y of the Health, Aging, and Body Composition (Health ABC) Study. In 1998-1999, dietary intake over the preceding year was measured by using a Block food-frequency questionnaire. Indicators of diet quality include the Healthy Eating Index (HEI), energy intake, and protein intake. Outcomes were determined annually by using measured weight and height and included the following: 1) incident PEM [body mass index (in kg/m2) <20, involuntary weight loss of ≥5% in the preceding year at any follow-up examination, or both] and 2) incident persistent PEM (having PEM at 2 consecutive follow-up examinations). Associations of indicators of diet quality with 4-y and 3-y incidence of PEM and persistent PEM, respectively, were examined by multivariable Cox regression analyses.

Results

The quality of the diet, as assessed with the HEI, was rated as "poor" for 6.4% and as "needs improvement" for 73.0% of the participants. During follow-up, 24.9% of the participants developed PEM and 8.5% developed persistent PEM. A poor HEI score was not associated with incident PEM or persistent PEM. Lower baseline energy intake was associated with a lower incidence of PEM (HR per 100-kcal/d lower intake: 0.98; 95% CI: 0.97, 0.99) and persistent PEM (HR: 0.97; 95% CI: 0.95, 0.99), although lower baseline protein intake was observed to be associated with a higher incidence of persistent PEM (HR per 10-g/d lower intake: 1.15; 95% CI: 1.03, 1.29).

Conclusions

These findings do not indicate that a poor diet quality is a risk factor for the long-term development of PEM in community-dwelling older adults, although there is an indication that lower protein intake is associated with higher PEM risk.

Nutritional variables predict chances of returning home and activities of daily living in post-acute geriatric care

Background

Little is known about the association between malnutrition and the chances of returning home from post-acute facilities in older adult patients. This study aimed to understand whether malnutrition and malnutrition-related factors would be determinants for returning home and activities of daily living (ADL) at discharge after post-acute care.

Methods

Patients aged ≥65 years living at home before the onset of an acute disease and admitted to a post-acute ward were enrolled (n=207) in this prospective observational study. Malnutrition was defined based on the criteria of the European Society for Clinical Nutrition and Metabolism. Nutritional parameters included the nutritional intake at the time of admission and oral conditions evaluated by the Oral Health Assessment Tool (OHAT). The Barthel Index was used to assess daily activities. A Cox regression analysis of the length of stay was performed. Multivariable linear regression analyses to determine associations between malnutrition, returning home, and ADL at discharge were performed, after adjusting the variables of acute care setting.

Results

The mean patient age was 84.7±6.7 years; 38% were men. European Society for Clinical Nutrition and Metabolism-defined malnutrition was observed in 129 (62.3%) patients, and 118 (57.0%) of all patients returned home. Multivariable regression analyses showed that malnutrition was a negative predictor of returning home (hazard ratio: 0.517 [0.351–0.761], p=0.001), and an increase in the nutritional intake (kcal/kg/d) was a positive predictor of the Barthel Index at discharge (coefficient: 0.34±0.15, p=0.021). The OHAT was not associated with returning home and ADL.

Conclusion

Malnutrition and nutritional intake are associated with returning home and ADL at discharge, respectively, after post-acute care. Further studies investigating the effects of a nutritional intervention for post-acute patients would be necessary.

Age modifies the association between serum obestatin, appetite and nutritional status in maintenance hemodialysis patients

BACKGROUND/OBJECTIVES

Increased age is strongly associated with anorexia and protein-energy wasting (PEW) in maintenance hemodialysis (MHD) population. We hypothesized that the association of obestatin, a recently discovered anorexigenic gut hormone, with appetite and nutritional status differs by age groups.

SUBJECTS/METHODS

We performed a cross-sectional study on 261MHD patients. Obestatin, acyl-ghrelin, markers of inflammation (CRP, IL-6, TNF-α) and nutrition (self-reported appetite, dietary intake, biochemical nutritional parameters, and body composition) were measured.

RESULTS

Obestatin was associated with appetite in multivariate analyses even after controlling for such confounders as lean body mass (LBM), IL-6 and acyl-ghrelin in patients younger than 71 years. For each ng/ml increase in obestatin levels, the odds for diminished appetite was 0.75 (95% CI: 0.59-0.96). However, these associations were not observed in patients 71 years and older. Multivariable logistic regression models (including appetite) also showed increasing odds for PEW (defined by ESPEN consensus-based criteria for the diagnosis of malnutrition) across increasing serum obestatin levels (OR: 1.51, 95% CI: 1.05-2.18) in patients 71 years and older. However, after lean body mass (LBM) was added to this model, the association between obestatin and malnutrition was abolished (OR: 1.26, 95% CI: 0.83-1.91).

CONCLUSIONS

The association between serum obestatin, appetite and PEW differs depending on age in MHD patients. A positive link with appetite exists in patients younger than 71 years, whereas this relationship disappears by the age of 71. In older MHD patients, obestatin is associated with PEW through mechanisms related to LBM, but not to appetite.

Nutritional deficiency during colonoscopy preparation: the forgotten iatrogeny

BACKGROUND AND AIMS

bowel preparation for colonoscopy induces a semi-fasting state, with a potential negative impact on fragile patients. The present study aims to quantify nutritional deficiency during colonoscopy preparation.

METHODS

this was an observational and cross-sectional study. A convenience sample was obtained that included adults that underwent colonoscopy after bowel preparation with Klean-Prep® according to the center protocol. Anthropometric evaluation was performed and nutritional deficiency was calculated via the quantification of energy and protein intake during the 48 hours prior to the examination which was compared with the individuals' needs. The association between nutritional deficiency with the quality of bowel preparation, age and status (hospitalized/ambulatory) was evaluated.

RESULTS

the study included 131 patients aged 21-91 years (mean 63.6 ± 13.2 years); 73 cases were male. Malnutrition reached 67.2% using specific anthropometric tools. A median preparation quality of six points was found when the Boston Bowel Preparation Scale was considered. The mean intake 48 hours prior to the procedure was 1,795 kcal and 100 g of protein. A daily energy intake of less than 50% of the individual needs was observed in 88 patients and less than 25% in 29 cases. The mean energy and protein deficiency were 59% (p < 0.01) and 45% (p < 0.01), and there was no correlation with preparation quality (p > 0.05). Nutritional defiency is similar in hospitalized and ambulatory patients (p > 0.05), but higher in older individuals (p = 0.04).

CONCLUSIONS

nutritional deficiency during colonoscopy preparation was significant, more so in older patients, and there was no correlation with the quality of bowel preparation. We conclude that bowel preparation regimens should be reformulated with an improved nutritional intake and the inclusion of nutritional supplements without residues.

The Role of Nutritional Status in Elderly Patients with Heart Failure

Evidence indicates that malnutrition very frequently co-occurs with chronic heart failure (HF) and leads to a range of negative consequences. Studies show associations between malnutrition and wound healing disorders, an increased rate of postoperative complications, and mortality. In addition, considering the increasing age of patients with HF, a specific approach to their treatment is required. Guidelines proposed by the European Society of Cardiology (ESC) for treating acute and chronic HF refer to the need to monitor and prevent malnutrition in HF patients. However, the guidelines feature no strict nutritional recommendations for HF patients, who are at high nutritional risk as a group, nor do they offer any such recommendations for the poor nutritional status subgroup, for which high morbidity and mortality rates have been observed. In the context of multidisciplinary healthcare, recommended by the ESC and proven by research to offer multifaceted benefits, nutritional status should be systematically assessed in HF patients. Malnutrition has become a challenge within healthcare systems and day-to-day clinical practice, especially in developed countries, where it affects the course of disease and patients' prognosis.

The final word on nutritional screening and assessment in older persons

PURPOSE OF REVIEW

To provide an updated perspective of how nutritional screening and assessment in older persons should be performed and reasonably implemented in the near future.

RECENT FINDINGS

Although nutritional screening and assessment should be fast and easy procedures, there is increasing evidence that more time should be dedicated to them. This is probably an answer to the claim to a medicine being more preventive than curative. Increasing interest is currently given to healthy aging and nutritional status is more likely to be addressed for its implications on functional status and disability. Important prognostic conditions, such as frailty, sarcopenia, and cachexia, which are closely linked to the nutritional domain, are at the top of the agenda. Therefore, body composition is a key issue and functional status is suggested as primary endpoint of nutrition trials. In this scenario, there is also a rationale for systematic assessment of inflammation, protein intake, and vitamin D status as potential contributing factors to reduced muscle mass and function.

SUMMARY

A 'second-generation' multidimensional nutritional screening and assessment including the evaluation of body composition, frailty, sarcopenia, and cachexia could be hypothesized. Nutritional assessment should be also completed by the systematic evaluation of inflammation, protein intake, and vitamin D status.

Community-Living Older Adults' Perceptions of Body Weight, Signs of Malnutrition and Sources of Information: a Descriptive Analysis of Survey Data

BACKGROUND

Community-living older adults may be susceptible to malnutrition (undernutrition) due to both physiological and non-physiological causes. The condition develops over time and the early signs and symptoms may not be obvious. Therefore awareness and early identification of nutrition risk factors may prevent, or at least slow, the progression of malnutrition.

OBJECTIVE

To describe community-living older adults' understanding of the signs of malnutrition, where they would seek malnutrition information and their self-perception of body weight.

DESIGN

Older adults (aged ≥ 65 years) living in the community setting completed an online or paper based questionnaire between May and August 2016. The questionnaire contained a mix of closed and open questions which related to weight perception, weight changes, perceived signs of malnutrition and sources of malnutrition information. Body mass index (BMI) from self-reported data was classified using BMI reference ranges for older adults and compared to self-perceived weight status. Textual data regarding the signs of malnutrition were analysed and reviewed by two authors using content analysis. Descriptive statistics were used to describe participant characteristics.

RESULTS

A total of 344 responses were received, the majority (90%) completed online. Mean participant age was 73 years and 57% of participants were female. Most (92%) reported their health to be good/very good. Body weight was perceived to be just right or more than it should be by 87% of underweight women and 97% of underweight men. Although 71% of the participants indicated their body weight had remained stable in the past six months, 37% reported they had been trying to change their weight. Signs of malnutrition resulted in four key categories of (i) psychological, (ii) physical appearance, (ii) bodily function and (iv) weight change. Very few reported the need to locate malnutrition information and indicated the top three sources for information would be (i) general practitioner, (ii) dietitian or (iii) internet.

CONCLUSION

This paper has presented useful data about malnutrition from the perspective of the community-living older adult. We found there may be uncertainty about the best weight, for older age. As many indicated they had been trying to change their weight, awareness needs to be raised regarding the impact of weight changes on health outcomes in this population. In this study, the internet appeared to be a key provider of nutrition information. Healthcare professionals need to consider how this can be used in an informative manner among community living older adults as a tool for raising awareness about nutrition risk and malnutrition.

Validity of the Self- Mini Nutritional Assessment (Self- MNA) for the Evaluation of Nutritional Risk. A Cross- Sectional Study Conducted in General Practice

INTRODUCTION

Malnutrition is a frequent condition in the elderly especially in hospitals and in nursing homes, and even among the free-living elders the prevalence is not negligible (5-10%). Awareness towards malnutrition is still limited. The lack of time for nutritional assessment by the overcommitted healthcare personnel, including the general practitioners (GPs), may represent one possible explanation for limited recognition of malnutrition. Therefore, a self-administered instrument could be useful in raising alert on the GPs and allow early detection of malnutrition and early care provision. The aim of the present study was to analyze the validity of the Self-MNA that takes cue from the Mini Nutritional Assessment- Short Form (MNA-SF) and has been adapted to be self-administered by free-living elderly subjects.

METHODS

Participants were recruited from patients referring to the GP offices in Italy. Nutritional evaluation was performed through the administration of Full-MNA, MNA-SF and Self-MNA. The comorbidity level was assessed through the Cumulative Illness Rating Scale (CIRS). The level of difficulty in filling out the test was reported by the participants, and the time spent to complete the Self-MNA was also registered.

RESULTS

A total of 226 subjects, 125 women and 101 men (75.1 ±8 and 75.3 ± 8 years old, respectively; p=0.89) were enrolled, and 214 (94.7%) of them completed the Self-MNA. According with the Full-MNA test score, 8.4% of women and 3.5% of men were classified as malnourished, whereas 32.7% of women and 31.4% of men were at risk of malnutrition. Agreement between Self-MNA and Full-MNA, and Self-MNA vs. MNA-SF was classified as "moderate" (k = 0.476 and 0.496 respectively; p < 0.001). Self-MNA showed a fair predictive value compared to the Full-MNA and MNA-SF tests (76.6 and 79.9%, respectively) with a barely adequate sensitivity (70.9 and 75.4%, respectively). The analysis of the characteristics of FN (false negative: subjects who were considered at risk of malnutrition or malnourished at Full-MNA but not at Self-MNA) showed that the clinical and functional aspects of these subjects (age, comorbidity and severity, time necessary to complete the Self-MNA, decrease in food intake, severe illness in the past 3 months, dementia and depression, fluid intake, need for feeding assistance, arm and calf circumferences) were very similar to the characteristics of true positive subjects. Patients required 6.7 ± 4.5 minutes to complete the test and 25 subjects (11.7%) needed more than 10 minutes, up to a maximum of 30 minutes. Patients who stated a greater difficulty were older (79.8 ± 7 vs. 73.5 ± 7 years; p<0.001), they were more «malnourished» at Full-MNA (10.7 vs. 1,7%; p= 0.006) and clinical status was characterized by a higher severity index (1.72 ± 0.6 vs. 1.41 ± 0.4; p= 0.008).

CONCLUSION

In the present study we investigated the validity of the Self-MNA in a sample of free-living elderly subjects. The results obtained confirm the validity of the test that may represent a useful tool for the GPs, although some important limitations need to be considered, limiting its use in clinical practice.

Association between Oropharyngeal Dysphagia and Malnutrition in Dutch Nursing Home Residents: Results of the National Prevalence Measurement of Quality of Care

OBJECTIVES

Nursing home residents often suffer from multi-morbidities and geriatric syndromes leading to lower quality of life or mortality. Oropharyngeal dysphagia (OD) and malnutrition are profound conditions in this complex profile of multi-morbidities and are associated with deprived mental -and physical health status, e.g. aspiration pneumonia or dehydration. This study aimed to assess the association between OD and malnutrition in Dutch nursing home residents.

DESIGN

Data for this cross-sectional study were obtained from the annual National Prevalence Measurement of Quality of Care (LPZ).

SETTING

The National Prevalence Measurement of Quality of Care was conducted in Nursing Homes in The Netherlands.

PARTICIPANTS

Participants were nursing home residents age 65 or older and admitted to psychogeriatric- or somatic wards.

MEASUREMENTS

The measurements were taken by trained nurses from the participating nursing homes. Anthropometric measurements and unintended weight loss (%) were assessed to determine nutritional status (malnutrition). OD was assessed by means of a standardized questionnaire assessing clinically relevant symptoms of OD such as swallowing problems or sneezing/coughing while swallowing. Cox regression was applied to assess the association between malnutrition and clinically relevant symptoms of OD in older Dutch nursing home residents.

RESULTS

Approximately 12% of the residents suffered from swallowing problems and 7% sneezed/coughed while swallowing liquids or solid foods. Approximately 10% of the residents was malnourished. Residents with OD symptoms were more often malnourished compared to residents without OD symptoms. Approximately 17% of the problematic swallowers were concurrently malnourished. Increased risk for malnutrition was found in residents suffering from swallowing problems (PR 1.5, 95%CI 1.2-1.9), as well as in residents that sneezed/coughed while swallowing (PR 1.3, 95%CI 1.0-1.7). Stratification based on wards revealed that problematic swallowers from somatic wards were at a high risk of malnutrition (PR 1.9, 95%CI 1.3-2.8).

CONCLUSION

Clinically relevant symptoms of oropharyngeal dysphagia, such as swallowing problems and sneezing/coughing while swallowing are associated with increased risk of malnutrition in psychogeriatric and somatic Dutch nursing home residents.

The burden and nature of malnutrition among patients in regional hospital settings: A cross-sectional survey

BACKGROUND/AIMS

Indigenous people experience a higher burden of nutrition-related conditions and are more likely to experience food insecurity compared to non-Indigenous people. Consequently, they remain at increased risk of malnutrition; particularly when residing in regional or remote areas. This study aims to compare and characterise the burden and nature of malnutrition among a representative cohort of Indigenous and non-Indigenous Australians admitted to regional hospitals for medical inpatient care.

METHODS

This was a cross-sectional survey conducted in three regional hospitals in the Northern Territory and Far North Queensland of Australia from February 2015 to September 2015. A total of 1606 adult medical inpatients were screened for eligibility. Of these, 608 eligible patients were screened for malnutrition using the validated Malnutrition Screening Tool and assessed for malnutrition using the Subjective Global Assessment. Socio-economic and health-related variables and anthropometric measurements were collected to identify the correlates of malnutrition.

RESULTS

Of the 271 Indigenous patients and 337 non-Indigenous patients screened and assessed for malnutrition, 250/608 (41.7%, 95% CI 40.1-52.3%) were found to be malnourished. Significantly higher rates of malnutrition (46.1%, 95% CI 40.1-52.3% versus 37.1%, 95% CI 31.9-42.5%) were found in Indigenous patients compared to non-Indigenous patients (P = 0.024). Higher rates of malnutrition were observed in Indigenous patients residing in Central Australia (56.7%, 95% CI 46.7-66.4%) than in the Top End of the Northern Territory (40.7%, 95% CI 31.7-50.1%) and in Far North Queensland (36.7%, 95% CI 23.4-51.7%). Factors independently predictive of malnutrition for both Indigenous and non-Indigenous participants included residence in Central Australia (OR 4.31, 95% CI 2.63-7.90, P < 0.001); an increased Charlson Comorbidity Index prognostic score (OR 1.37 [per incremental score], 95% CI 1.19-1.59, P < 0.001); and an underweight Body Mass Index (OR 29.97, 95% CI 3.68-244.0, P < 0.001). Of the 250/608 patients who were malnourished, the positive predictor value (PPV) for malnourished patients who were underweight was 96.6% (95% CI 88.3-99.6%); for Indigenous Australians who were malnourished and underweight, the PPV was 100%. A mid-upper arm circumference of less than 23 cm demonstrated a strong PPV for all patients who were malnourished (96.1%, 95% CI 89.0-99.2%).

CONCLUSION

This is the first study to characterise malnutrition in adult Indigenous Australians in a hospital inpatient setting. Compared to non-Indigenous patients the burden and pattern of malnutrition was both higher and markedly different among Indigenous patients. These data highlight the critical importance for actively screening for and responding to malnutrition in this vulnerable patient population in regional and remote settings.

Malnutrition and cachexia among cancer out-patients in Nairobi, Kenya

Cancer is the third leading cause of death in Kenya. However, there is scarce information on the nutritional status of cancer patients to guide in decision making. The present study sought to assess the risk of malnutrition, and factors associated with malnutrition and cachexia, among cancer out-patients, with the aim of informing nutrition programmes for cancer management in Kenya and beyond. This was a facility-based cross-sectional study performed at Kenyatta National Hospital and Texas Cancer Centre in Nairobi, Kenya. The risk of malnutrition was assessed using the Malnutrition Universal Screening Tool (MUST). Diagnoses of malnutrition and cachexia were done using the European Society of Clinical Nutrition and Metabolism (ESPEN) and Fearon criteria, respectively. A total of 512 participants were assessed. Those at risk of malnutrition were 33·1 % (12·5 % at medium risk, 20·6 % at high risk). Prevalence of malnutrition was 13·4 %. The overall weight loss >5 % over 3 months was 18·2 % and low fat-free mass index was 43·1 %. Prevalence of cachexia was 14·1 % compared with 8·5 % obtained using the local criteria. Only 18·6 % participants had received any form of nutrition services. Age was a predictor of malnutrition and cachexia in addition to site of cancer for malnutrition and cigarette smoking for cachexia. The use of the MUST as a screening tool at the first point of care should be explored. The predictive value of current nutrition assessment tools, and the local diagnostic criteria for malnutrition and cachexia should be reassessed to inform the development of appropriate clinical guidelines and future capacity-building initiatives that will ensure the correct identification of patients at risk for timely care.

Characteristics and Outcomes of Adult Inpatients With Malnutrition

BACKGROUND

The diagnosis of malnutrition remains controversial. Furthermore, it is unknown if physician diagnosis of malnutrition impacts outcomes. We sought to compare outcomes of patients with physician diagnosed malnutrition to patients recognized as malnourished by registered dietitians (RDs), but not physicians, and to describe the impact of each of 6 criteria on the diagnosis of malnutrition.

METHODS

We conducted a retrospective cohort study of adult patients identified as meeting criteria for malnutrition. Pediatric, psychiatric, maternity, and rehabilitation patients were excluded. Patient demographics, clinical data, malnutrition type and criteria, nutrition interventions, and outcomes were abstracted from the electronic medical record.

RESULTS

RDs identified malnutrition for 291 admissions during our study period. This represents 4.1% of hospital discharges. Physicians only diagnosed malnutrition on 93 (32%) of these cases. Physicians diagnosed malnutrition in 43% of patients with a body mass index <18.5 but only 26% of patients with body mass index higher than 18.5. Patients with a physician diagnosis had a longer length of stay (mean 14.9 days vs 7.1 days) and were more likely to receive parenteral nutrition (PN) (20.4% vs 4.6%). Of the patients, 62% had malnutrition due to chronic illness. Of the 6 criteria used to identify malnourished patients, weight loss and reduced energy intake were the most common.

CONCLUSIONS

Malnutrition is underrecognized by physicians. However, further research is needed to determine if physician recognition and treatment of malnutrition can improve outcomes. The most important criteria for identifying malnourished patients in our cohort were weight loss and reduced energy intake.

Association between Malnutrition and 28-Day Mortality and Intensive Care Length-of-Stay in the Critically ill: A Prospective Cohort Study

There is limited evidence for the association between malnutrition and mortality as well as Intensive Care Unit length-of-stay (ICU-LOS) in critically ill patients. We aimed to examine the aforementioned associations by conducting a prospective cohort study in an ICU of a Singapore tertiary hospital. Between August 2015 and October 2016, all adult patients with ≥ 24 h of ICU-LOS were included. The 7-point Subjective Global Assessment (7-point SGA) was used to determine patients’ nutritional status within 48 h of ICU admission. Multivariable regressions were conducted in two ways: (1) presence versus absence of malnutrition, and (2) dose-dependent association for each 1-point decrease in the 7-point SGA. There were 439 patients of which 28.0% were malnourished, and the 28-day mortality rate was 28.0%. Malnutrition was associated with an increased risk of 28-day mortality (adjusted Relative Risk 1.33 (95% Confidence Interval: 1.05–1.69)), and this risk increased with a greater degree of malnutrition (adjusted Relative Risk 1.08 (95% Confidence Interval: 1.00–1.16) for each 1-point decrease in the 7-point SGA). No significant association was found between malnutrition and ICU-LOS. The results of this study indicated a clear association between malnutrition and higher 28-day mortality in critically ill patients. The association between malnutrition and ICU-LOS could not be replicated and hence requires further evaluation.

Percentiles for skeletal muscle index, area and radiation attenuation based on computed tomography imaging in a healthy Caucasian population

Background/objectives

Muscle mass is a key determinant of nutritional status and associated with outcomes in several patient groups. Computed tomography (CT) analysis is increasingly used to assess skeletal muscle area (SMA), skeletal muscle index (SMI) and muscle radiation attenuation (MRA). However, interpretation of these muscle parameters is difficult since values in a healthy population are lacking. The aim of this study was to provide sex specific percentiles for SMA, SMA and MRA in a healthy Caucasian population and to examine the association with age and BMI in order to define age- and BMI specific percentiles.

Subjects/methods

In this retrospective cross-sectional study CT scans of potential kidney donors were used to assess SMA, SMI and MRA at the level of the third lumbar vertebra. Sex specific distributions were described and, based on the association between age/BMI and muscle parameters, age, and BMI specific predicted percentiles were computed. The 5th percentile was considered as cut-off.

Results

CT scans of 420 Individuals were included (age range 20–82 years and BMI range 17.5–40.7 kg/m²). Sex specific cut-offs of SMA, SMI and MRA were 134.0 cm², 41.6 cm²/m² and 29.3 HU in men and 89.2 cm², 32.0 cm²/m² and 22.0 HU in women, respectively. Correlations were negative between age and all three muscle parameters, positive between BMI and SMA/SMI and negative between BMI and MRA, resulting in age- and BMI specific percentiles.

Conclusions

This study provides sex specific percentiles for SMA, SMI, and MRA. In addition, age- and BMI specific percentiles have been established.

The New European Society for Clinical Nutrition and Metabolism Definition of Malnutrition: Application for Nutrition Assessment and Prediction of Morbimortality in an Emergency Service

BACKGROUND

Recently, the European Society for Clinical Nutrition and Metabolism (ESPEN) provided novel consensus criteria for malnutrition diagnosis. This study aimed to evaluate the applicability of this instrument in combination with different nutrition screening tools (1) to identify malnutrition and (2) to predict morbidity and mortality in hospitalized patients.

MATERIALS AND METHODS

Observational prospective study in 750 adults admitted to the emergency service of a tertiary public hospital. Subjective Global Assessment (SGA-reference method) and the new ESPEN criteria were used to assess nutrition status of patients, who were initially screened for nutrition risk using 4 different tools. Outcome measures included length of hospital stay, occurrence of infection, and incidence of death during hospitalization, analyzed by logistic regression.

RESULTS

There was a lack of agreement between the SGA and ESPEN definition of malnutrition, regardless of the nutrition screening tool applied previously (κ = -0.050 to 0.09). However, when Malnutrition Screening Tool and Nutritional Risk Screening-2002 (NRS-2002) were used as the screening tool, malnourished patients according to ESPEN criteria showed higher probability of infection (relative risk [RR], 1.54; 95% confidence interval [CI], 1.02-2.31 and RR, 2.06; 95% CI, 1.37-3.10, respectively), and when the NRS-2002 was used, the risk for death was 2.7 times higher (hazard ratio, 2.69; 95% CI, 1.07-6.81) in malnourished patients than in well-nourished patients.

CONCLUSION

Although the new ESPEN criteria had a poor diagnostic value, it seems to be a prognostic tool among hospitalized patients, especially when used in combination with the NRS-2002.

Nutrition Screening vs Nutrition Assessment: What's the Difference?

Screening and assessment imply different processes, with the former indicating risk factors for a deprived nutrition condition and the latter providing the nutrition diagnosis. Both should be routinely performed at hospital admission according to recommended guidelines; however, this is not the reality worldwide, and undernutrition remains highly prevalent in the hospital setting. Therefore, the objective of the current review is to delve into the principles leading to nutrition status deficiencies and how they should be addressed by screening and assessment. A critical appraisal for the reasons associated with the misunderstanding between screening and assessing is proposed without further discussing the many available screening tools while approaching some of the assessment instruments.

Worse survival after breast cancer in women with anorexia nervosa

PURPOSE

A history of anorexia nervosa has been associated with a reduced risk of developing breast cancer. We investigated survival after breast cancer among women with a prior anorexia nervosa diagnosis compared with women in a population comparison group.

METHODS

This register-based study included combined data from Sweden, Denmark and Finland. A total of 76 and 1462 breast cancer cases identified among 22,654 women with anorexia nervosa and 224,619 women in a population comparison group, respectively, were included in the study. Hazard ratios (HR) for overall and breast cancer-specific mortality after breast cancer diagnosis were estimated using Cox regression. Cause of death was available only for Swedish and Danish women; therefore, the analysis on breast cancer-specific mortality was restricted to these women.

RESULTS

We observed 23 deaths after breast cancer among anorexia nervosa patients and 247 among population comparisons. The overall mortality after the breast cancer diagnosis was increased in women with a history of anorexia nervosa compared with population comparisons (HR 2.5, 95% CI 1.6-3.9) after adjustment for age, period and extent of disease. Results were similar for overall (HR 2.3, 95% CI 1.4-3.6) and breast cancer-specific mortality (HR 2.1, 95% CI 1.3-3.6) among Swedish and Danish women.

CONCLUSIONS

We found that female breast cancer patients with a prior diagnosis of anorexia nervosa have a worse survival compared with other breast cancer patients.

Malnutrition and sarcopenia in a large cohort of patients with systemic sclerosis

Systemic sclerosis (SSc) is an autoimmune disease which may lead to malnutrition. Previous studies have defined it with different criteria. No thorough evaluations of sarcopenia in SSc are available. The aim of the present study was to assess the prevalence and the potential association of malnutrition and sarcopenia in a large cohort of SSc cases. A total of 141 SSc consecutive outpatients were enrolled. Body composition was analyzed by densitometry. Malnutrition was defined according to recently published ESPEN criteria, whereas sarcopenia was diagnosed in patients with reduced skeletal muscle index. Malnutrition was diagnosed in 9.2% of patients (95% CI, 4.4-14.0%). Malnourished patients had worse gastrointestinal symptoms according to UCLA SCTC GIT 2.0 questionnaire (p = 0.007), lower physical activity (p = 0.028), longer disease duration (p = 0.019), worse predicted DLCO/VA and FVC (p = 0.009, respectively), worse disease severity according to Medsger severity score (p < 0.001), lower hemoglobin (p = 0.023), and fat-free mass (p < 0.001) and were more often sarcopenic (p < 0.001). In multivariate analysis, only FVC (p = 0.006) and disease severity (p = 0.003), in particular for the lungs (p = 0.013), were confirmed to be worse in malnourished patients. Sarcopenia was diagnosed in 29\140 patients (20.7%; 95% CI, 14.0-27.4%); 11\29 were also malnourished. In multivariate analysis, sarcopenic patients had longer disease duration (p = 0.049), worse DLCO/VA (p = 0.002), and lung (p = 0.006) and skin (p = 0.014) involvement. In SSc, malnutrition defined with ESPEN criteria was found to be lower than previously reported. Sarcopenia was found to be somewhat common. Lung involvement was significantly associated with nutritional status and may not be explained only by muscle weakness.

Nutrition and Muscle in Cirrhosis

As the cirrhosis progresses, development of complication like ascites, hepatic encephalopathy, variceal bleeding, kidney dysfunction, and hepatocellular carcinoma signify increasing risk of short term mortality. Malnutrition and muscle wasting (sarcopenia) is yet other complications that negatively impact survival, quality of life, and response to stressors, such as infection and surgery in patients with cirrhosis. Conventionally, these are not routinely looked for, because nutritional assessment can be a difficult especially if there is associated fluid retention and/or obesity. Patients with cirrhosis may have a combination of loss of skeletal muscle and gain of adipose tissue, culminating in the condition of "sarcopenic obesity." Sarcopenia in cirrhotic patients has been associated with increased mortality, sepsis complications, hyperammonemia, overt hepatic encephalopathy, and increased length of stay after liver transplantation. Assessment of muscles with cross-sectional imaging studies has become an attractive index of nutritional status evaluation in cirrhosis, as sarcopenia, the major component of malnutrition, is primarily responsible for the adverse clinical consequences seen in patients with liver disease. Cirrhosis is a state of accelerated starvation, with increased gluconeogenesis that requires amino acid diversion from other metabolic functions. Protein homeostasis is disturbed in cirrhosis due to several factors such as hyperammonemia, hormonal, and cytokine abnormalities, physical inactivity and direct effects of ethanol and its metabolites. New approaches to manage sarcopenia are being evolved. Branched chain amino acid supplementation, Myostatin inhibitors, and mitochondrial protective agents are currently in various stages of evaluation in preclinical studies to prevent and reverse sarcopenia, in cirrhosis.

Effects of a Home-Based and Volunteer-Administered Physical Training, Nutritional, and Social Support Program on Malnutrition and Frailty in Older Persons: A Randomized Controlled Trial

OBJECTIVES

The aim of this study was to examine the effects of a home-based and volunteer-administered physical training and nutritional intervention program compared with social support intervention on nutritional and frailty status in prefrail and frail community-dwelling older persons.

DESIGN

This was a randomized controlled trial in which community-dwelling persons (mean age = 83 years) were recruited and randomly assigned to the physical training and nutritional intervention group (PTN, n = 39) and the social support group (SoSu, n = 41). The study was conducted by trained lay nonprofessionals.

SETTING

The community-dwelling older persons in both groups were visited twice a week by trained nonprofessional volunteers (buddies) in Vienna, Austria.

PARTICIPANTS

Eighty prefrail and frail adults aged 65 years or older.

INTERVENTION

In the PTN group, both the buddies and older persons performed 6 strength exercises within a circuit training session and discussed nutrition-related aspects. The active control group (SoSu) had the opportunity to perform cognitive training in addition to the social contact.

MEASUREMENTS

Outcome measures as nutritional (Mini Nutritional Assessment long form [MNA-LF]) and frailty status (Frailty Instrument for Primary Care of the Survey of Health, Ageing and Retirement in Europe [SHARE-FI]) were obtained at baseline and after 12 weeks.

RESULTS

Significant improvements in the MNA-LF score (1.54 points, 95% confidence interval [CI] 0.51-2.56; P = .004) and the SHARE-FI score (-0.71 discrete factor score values, 95% CI -1.07, -0.35; P < .001) were observed in the PTN group after 12 weeks. In both groups, the prevalence of impaired nutritional status and frailty decreased significantly over time. The prevalence of impaired nutritional status decreased by 25% in the PTN group and by 23% in the SoSu group. Moreover, the prevalence of frailty decreased by 17% in the PTN group and by 16% in the SoSu group. The presence of impaired nutritional status at baseline was independently associated with greater changes in the nutritional (adjusted odds ratio [OR] 3.18, 95% CI 1.26-7.98; P = .014) and frailty status (adjusted OR 3.16, 95% CI 1.01-9.93; P = .049) after 12 weeks.

CONCLUSION

The results indicate that a home-based physical training, nutritional, and social support intervention conducted by nonprofessionals is feasible and can help to tackle malnutrition and frailty in older persons living at home. Furthermore, social support alone also can result in improvement. In particular, older adults with impaired nutritional status at baseline can benefit more from the intervention. Such a home visit program might also have the potential to prevent future health risks and could allay isolation and loneliness.

Nutritional status plays a crucial role in the mortality of critically ill patients with acute renal failure

We aimed to clarify associations between nutritional status and mortality in patients with acute renal failure. De-identified data were obtained from the Medical Information Mart for Intensive Care III database comprising more than 40,000 critical care patients treated at Beth Israel Deaconess Medical Centerbetween 2001 and 2012. Weight loss and body mass index criteria were used to define malnutrition. Data of 193 critically ill patients with acute renal failure were analyzed, including demographics, nutrition intervention, laboratory results, and disease severity. Main outcomes were in-hospital and 1-year mortality. The 1-year mortality was significantly higher in those with malnutrition than in those without malnutrition (50.0% vs 29.3%, p=0.010), but differences in in-hospital survival were not significant (p=0.255). Significant differences in mortality were found between those with malnutrition and without starting at the 52nd day after intensive care unit (ICU) discharge (p=0.036). No significant differences were found between men and women with malnutrition in in-hospital mortality (p=0.949) and 1-year mortality (p=0.051). Male patients requiring intervention with blood products/colloid supplements had greater risk of 1-year mortality, but without statistical significance. Nutritional status is a predictive factor for mortality among critically ill patients with acute renal failure, particularly 1-year mortality after ICU discharge.

Changes in body mass index and mid-upper arm circumference in relation to all-cause mortality in older adults

BACKGROUND & AIMS

The assessment of weight loss as an indicator of poor nutritional status in older persons is currently widely applied to establish risk of mortality. Little is known about the relationship between changes in mid-upper arm circumference (MUAC) and mortality in older individuals. The aim of the present study was to examine the association between 3-year change in MUAC and 20-year mortality in community-dwelling older adults and compare this to the association between body mass index (BMI) change and mortality.

METHODS

Data on changes in MUAC (cm) and BMI (kg/m²), covariates, and mortality were available for 1307 Dutch older adults (49.7% men) aged 65 years and older in 1995/96 (mean 75.6 years, SD 6.5) from Longitudinal Aging Study Amsterdam (LASA). Anthropometric measurements were performed in 1992/93 with repeated measurements in 1995/96 (baseline), and a mortality follow up until July 2015. BMI and MUAC change were divided into quintiles, with the quintile including zero defined as the reference category. Cox regression analyses were performed to examine the associations of 3-year changes in MUAC and BMI with subsequent 20-year all-cause mortality, adjusted for demographic and health factors. Age, sex and initial measurement of BMI and MUAC (1992/93) were tested for effect modification (P = <0.10).

RESULTS

Mean baseline BMI was 26.7 kg/m² (SD 4.2) with a 3-year change of -0.2 (SD 1.5). Mean baseline MUAC was 30.5 cm (SD 3.5) with a 3-year change of -0.8 (SD 1.6). Age, sex, and BMI and MUAC 3 years prior were effect modifiers in the associations between change in anthropometric measurement and mortality. Decrease in MUAC was not associated with mortality in persons with a higher initial MUAC (≥31 cm), while for persons with a lower initial MUAC, a decrease in MUAC of ≤-2.15 was associated with increased mortality risk (HR 1.54; 95% CI: 1.14-2.09), also when further stratified on median age and sex. In stratified analysis of BMI change for median initial BMI (26.5) and additionally stratified for median age and sex, the associations between a BMI decrease of ≤-1.19 and mortality fluctuated, mostly statistically not significant. No associations were found for gain in MUAC or BMI.

CONCLUSIONS

Given that MUAC loss is more strongly and consistently associated with an increased mortality risk in older individuals with a low initial MUAC compared to BMI loss, this may be a more recommendable measure to use in clinical practice for assessing poor nutritional status, instead of weight loss.

Percutaneous endoscopic gastrostomy feeding of locally advanced oro-pharygo-laryngeal cancer patients: Blenderized or commercial food?

OBJECTIVES

Head and neck cancer patients commonly suffer from severe malnutrition at the time of tentative diagnosis. Percutaneous Endoscopic Gastrostomy [PEG] feeding is now considered as an efficient tool to reduce nutritional deterioration alongside concurrent treatment. We undertook the challenge to retrospectively evaluate the impact of a commercial, disease-specific, feeding formula [Supportan, Fresenius Kabi, Hellas] versus blenderized family food on nutritional outcome.

MATERIALS AND METHODS

This is a retrospective analysis of prospectively collected nutritional and anthropometric data at the time of PEG placement, at the 8th week [after treatment termination] and at 8 months [6mo of recovery from treatment]. All patients were prescribed a commercial feeding formula.

RESULTS

The final dataset included 212 patients: 112 received the commercial formula, 69 voluntarily decided to switch into blenderized-tube-feeding, and 31 were prescribed to receive a home-made formula of standard ingredients. The commercial formula seemed to help patients to fight the catabolism of concurrent treatment, since, at the 8mo assessment, both Body Mass index and Fat Free Mass had almost recovered to the values at the time of first diagnosis. Neither group on blenderized or home-made formulas exhibited nutritional improvement, but experienced a significant deterioration throughout the study period, with the home-made formula group being the worst.

CONCLUSION

These findings clearly indicate that home-made and blenderized foods do not adequately support the nutritional requirements of patients with HNC scheduled to receive concurrent CRT treatment.

Nutritional counseling with or without systematic use of oral nutritional supplements in head and neck cancer patients undergoing radiotherapy

BACKGROUND

To evaluate the benefit of oral nutritional supplements (ONS) in addition to nutritional counseling in head and neck cancer (HNC) patients undergoing radiotherapy (RT).

METHODS

In a single-center, randomized, pragmatic, parallel-group controlled trial (ClinicalTrials.gov: NCT02055833; February 2014-August 2016), 159 newly diagnosed HNC patients suitable for to RT regardless of previous surgery and induction chemotherapy were randomly assigned to nutritional counseling in combination with ONS (N = 78) or without ONS (N = 81) from the start of RT and continuing for up to 3 months after its end. Primary endpoint was the change in body weight at the end of RT. Secondary endpoints included changes in protein-calorie intake, muscle strength, phase angle and quality of life and anti-cancer treatment tolerance.

RESULTS

In patients with the primary endpoint assessed (modified intention-to-treat population), counseling plus ONS (N = 67) resulted in smaller loss of body weight than nutritional counseling alone (N = 69; mean difference, 1.6 kg [95%CI, 0.5-2.7]; P = 0.006). Imputation of missing outcomes provided consistent findings. In the ONS-supplemented group, higher protein-calorie intake and improvement in quality of life over time were also observed (P < 0.001 for all). The use of ONS reduced the need for changes in scheduled anti-cancer treatments (i.e. for RT and/or systemic treatment dose reduction or complete suspension, HR=0.40 [95%CI, 0.18-0.91], P = 0.029).

CONCLUSION

In HNC patients undergoing RT or RT plus systemic treatment, and receiving nutritional counseling, the use of ONS resulted in better weight maintenance, increased protein-calorie intake, improved quality of life and was associated with better anti-cancer treatment tolerance.

A low proportion of malnourished patients receive nutrition treatment - results from nutritionDay

NutritionDay is a yearly point-prevalence study of malnutrition in hospitals from more than 50 countries. The aim of the present study was to quantify the frequency of malnutrition and the proportion of malnourished patients receiving nutritional treatment in two university hospitals in Norway using data from nutritionDay. All units at Oslo University Hospital (OUH) and University Hospital of Northern Norway (UNN) were invited to participate in nutritionDay 2014, and 28 out of 85 eligible units agreed to take part. Malnutrition was diagnosed based on body mass index (BMI), weight reduction and food intake in the previous week, according to national guidelines and ESPEN criteria. Data from 488 patients were available, representing 90.1% of occupied beds in participating units. Thirty percent of the patients were diagnosed malnourished when national criteria were used, and only 41% of these patients received nutritional treatment. The estimated malnutrition rate was 11% when the ESPEN consensus criteria were used. Data on weight or height were frequently missing in the patient records, and BMI could only be calculated in two-thirds of the patients. The frequency of low BMI (<18.5 kg/m²) was only 5%. Involuntary weight loss was present in 37% of the patients, and 60% had eaten less than normal in the previous week. Oncology units had the highest frequency of patients with low BMI, and the highest weight loss and overall malnutrition rate. Surgery and geriatric units had the highest rate of patients with low food intake. In this study, nearly 60% of the malnourished patients did not receive any nutritional treatment, and this indicates a potential for improved nutritional care and cost savings. Low food intake and weight loss were frequent at these two Norwegian hospitals, and in line with previous reports from nutritionDay in other countries.

Health determinants and survival in nursing home residents in Europe: Results from the SHELTER study

OBJECTIVE

The care processes directed towards institutionalized older people needs to be tailored on goals and priorities that are relevant for this specific population. The aim of the present study was (a) to describe the distribution of selected health determinants in a sample of institutionalized older adults, and (b) to investigate the impact on survival of such measures.

DESIGN

Multicentre longitudinal cohort-study.

SETTING

57 nursing homes (NH) in 7EU countries (Czech Republic, England, Finland, France, Germany, Italy, The Netherlands) and 1 non-EU country (Israel).

PARTICIPANTS

3036 NH residents participating in the Services and Health for Elderly in Long TERm care (SHELTER) study.

MEASUREMENTS

We described the distribution of 8 health determinants (smoking habit, alcohol use, body mass index [BMI], physical activity, social participation, family visits, vaccination, and preventive visits) and their impact on 1-year mortality.

RESULTS

During the one-year follow up, 611 (20%) participants died. Overweight (HR 0.79; 95% C.I. 0.64-0.97) and obesity (HR 0.64; 95% C.I. 0.48-0.87) resulted associated with lower mortality then normal weight. Similarly, physical activity (HR 0.67; 95% C.I. 0.54-0.83), social activities (HR 0.63; 95% C.I. 0.51-0.78), influenza vaccination (HR 0.66; 95% C.I. 0.55-0.80) and pneumococcal vaccination (HR 0.76 95% C.I. 0.63-0.93) were associated with lower mortality. Conversely, underweight (HR 1.28; 95% C.I. 1.03-1.60) and frequent family visits (HR 1.75; 95% C.I. 1.27-2.42) were associated with higher mortality.

CONCLUSIONS

Health determinants in older NH residents depart from those usually accounted for in younger and fitter populations. Ad hoc studies are warranted in order to describe other relevant aspects of health in frail older adults, with special attention on those institutionalized, with the ultimate goal of improving the quality of care and life.

Assessing the nutritional status of hospitalized elderly

Purpose

The increasing number of elderly people worldwide throughout the years is concerning due to the health problems often faced by this population. This review aims to summarize the nutritional status among hospitalized elderly and the role of the nutritional assessment tools in this issue.

Methods

A literature search was performed on six databases using the terms “malnutrition”, “hospitalised elderly”, “nutritional assessment”, “Mini Nutritional Assessment (MNA)”, “Geriatric Nutrition Risk Index (GNRI)”, and “Subjective Global Assessment (SGA)”.

Results

According to the previous studies, the prevalence of malnutrition among hospitalized elderly shows an increasing trend not only locally but also across the world. Under-recognition of malnutrition causes the number of malnourished hospitalized elderly to remain high throughout the years. Thus, the development of nutritional screening and assessment tools has been widely studied, and these tools are readily available nowadays. SGA, MNA, and GNRI are the nutritional assessment tools developed specifically for the elderly and are well validated in most countries. However, to date, there is no single tool that can be considered as the universal gold standard for the diagnosis of nutritional status in hospitalized patients.

Conclusion

It is important to identify which nutritional assessment tool is suitable to be used in this group to ensure that a structured assessment and documentation of nutritional status can be established. An early and accurate identification of the appropriate treatment of malnutrition can be done as soon as possible, and thus, the malnutrition rate among this group can be minimized in the future.

Body composition assessment of Crohn's outpatients and comparison with gender- and age-specific multiple matched control pairs

BACKGROUND/OBJECTIVES

Routine clinical care for Crohn's disease (CD) outpatients does not cover the assessment of body composition (BC); although this disease (because of inflammation, surgeries, lack of physical activity and appetite) may have a severe impact on lean body mass. The main aims of this prospective research were to assess the nutritional status of the patients and to compare their data with apparently healthy gender- and age-specific matched control pairs.

SUBJECTS/METHODS

Overall, 136 CD patients and 1752 apparently healthy people were involved in the study. All participants were measured by the same bioelectrical impedance analyser.

RESULTS

Using body mass index (BMI) and fat-free mass index (FFMI) as the markers of nutritional status, we found low BMI for 21% of the patients and low FFMI for 30% of them. Low BMI values were not gender specific, but substantially more females had low FFMI values. Low BMI was diagnosed in the patients' vs the control group for 21 vs 4% for men and 21 vs 2% for women; whereas low FFMI was diagnosed for 25 vs 5% for men and 36 vs 14% for women. Significant differences were found between patients' and control groups (median BMI: 22.0 vs 25.1 kg/m2, P<0.0001; FFMI: 17.3 vs 18.4 kg/m2, P=0.0044).

CONCLUSIONS

This study confirmed the higher prevalence of low FFMI than that of low BMI among the subjects. We recommend implementing the assessment of BC into routine clinical care to diagnose low FFMI and to start intervention in time.

Handgrip Strength Is Associated With Treatment Modifications During Neoadjuvant Chemoradiation in Patients With Esophageal Cancer

RATIONALE

It has been shown that early nutrition intervention improves nutrition status (NS) and treatment tolerance in patients with esophageal cancer. However, it remains unknown whether pretreatment parameters of NS are associated with treatment modifications (TMs) during neoadjuvant chemoradiation (CR) in patients who are intensively nutritionally supervised during treatment.

METHODS

All outpatients with esophageal cancer who were scheduled for CR in the VU medical center from 2006-2015 were included. NS was assessed by body mass index (BMI), weight loss in the past 6 months (WL), fat mass index (FMI) and fat-free mass index (FFMI), handgrip strength (HGS), and energy/protein intake. Logistic regression analyses, adjusted for age, sex, previous tumor, tumor stage, and physical status, were applied. TMs were defined as delay, dose reduction or discontinuation of chemotherapy and/or radiotherapy, hospitalization, or mortality (yes/no).

RESULTS

In total, 162 patients were included (73% male; mean age 65 ± 9 years). Mean BMI was 25.1 ± 4.5 kg/m2, and WL was 4.8 ± 5.1 kg. HGS and FFMI were below the 10th percentile of reference values in 21 and 37 patients, respectively. Thirty-five (22%) patients experienced at least 1 TM during CR; unplanned hospitalization (n = 18, 11%) was the most prevalent. After adjustments for confounders, only HGS was statistically significantly associated with TMs (odds ratio, 0.93; 95% confidence interval, 0.88-1.00).

CONCLUSION

In this group of intensively supervised patients with esophageal cancer, pretreatment parameters of NS had little influence on TMs during CR. Only a lower HGS was associated with TMs.

The prevalence of sarcopenia is markedly increased in patients with intestinal failure and associates with several risk factors

BACKGROUND & AIMS

Intestinal insufficiency and intestinal failure are conditions associated with malabsorption of micro- and macronutrients. Consequently, malnutrition and ensuing alterations in body composition are common in this context and patients may have an increased risk of progressive loss of skeletal muscle mass and function (i.e. sarcopenia). We investigated the prevalence of sarcopenia in patients with intestinal insufficiency and intestinal failure and identified associated risk factors.

METHODS

This was a cross-sectional study including 113 clinically stable outpatients with intestinal insufficiency or intestinal failure. Body composition was assessed using bioelectrical impedance analysis and muscle function (strength or performance) using a handheld dynamometer and a timed up-and-go test. Sarcopenia was classified using the European Working Group on Sarcopenia in Older People criteria. Several parameters, including smoking, alcohol, and concurrent morbidities, were analyzed for association with sarcopenia.

RESULTS

The prevalence of sarcopenia was 53.1% (95% CI; 43.8 to 62.2) in the combined patient group. In patients with intestinal failure the prevalence of sarcopenia was 72.7% (95% CI; 59.3 to 83.0) compared to 34.5% (95% CI; 23.3 to 47.8) in those with intestinal insufficiency (OR 5.07 [95% CI; 2.27 to 11.31]; p < 0.001). Excessive alcohol consumption (OR 7.69 [95% CI; 1.50 to 39.34]; p = 0.014), intestinal failure (OR 4.16 [95% CI; 1.69 to 10.28]; p = 0.002), and inflammatory activity (OR 3.83 [95% CI; 1.06 to 12.84]; p = 0.041), were identified as independent risk factors of sarcopenia. A trend was observed for hypermetabolism in multivariate analysis (OR 7.55 [95% CI; 0.79 to 72.03]; p = 0.079).

CONCLUSIONS

Patients with intestinal insufficiency and intestinal failure are at immense risk of developing sarcopenia. Associated risk factors are excessive alcohol consumption, intestinal failure, and inflammatory activity.

Severe childhood malnutrition

The main forms of childhood malnutrition occur predominantly in children <5 years of age living in low-income and middle-income countries and include stunting, wasting and kwashiorkor, of which severe wasting and kwashiorkor are commonly referred to as severe acute malnutrition. Here, we use the term 'severe malnutrition' to describe these conditions to better reflect the contributions of chronic poverty, poor living conditions with pervasive deficits in sanitation and hygiene, a high prevalence of infectious diseases and environmental insults, food insecurity, poor maternal and fetal nutritional status and suboptimal nutritional intake in infancy and early childhood. Children with severe malnutrition have an increased risk of serious illness and death, primarily from acute infectious diseases. International growth standards are used for the diagnosis of severe malnutrition and provide therapeutic end points. The early detection of severe wasting and kwashiorkor and outpatient therapy for these conditions using ready-to-use therapeutic foods form the cornerstone of modern therapy, and only a small percentage of children require inpatient care. However, the normalization of physiological and metabolic functions in children with malnutrition is challenging, and children remain at high risk of relapse and death. Further research is urgently needed to improve our understanding of the pathophysiology of severe malnutrition, especially the mechanisms causing kwashiorkor, and to develop new interventions for prevention and treatment.

Elderly Nutritional Indicators for Geriatric Malnutrition Assessment (ENIGMA): Development and validation of a nutritional prognostic index

BACKGROUND

Few nutritional measurement tools have been validated that predict long-term mortality risks in community-living older persons.

OBJECTIVE

To develop and validate a new nutritional prognostic index (ENIGMA) for use in geriatric outpatient or primary care.

DESIGN

We developed the ENIGMA (four questions: unable to shop, cook or feed one's self, difficulty eating due to oral problem, eat few fruits or vegetables, 3 or more drugs a day, and four blood indicators: low albumin, hemoglobin, total cholesterol and lymphocyte count), and evaluated its predictive validity for 10 years mortality outcome in a development cohort (N = 1550) of community-living older persons, in comparison with the Geriatric Nutritional Risk Index (GNRI), Mini Nutritional Assessment (MNA) and ESPEN Malnutrition (ESPEN-M), and calibrated it externally in a validation cohort (N = 924).

RESULTS

In the development cohort, ENIGMA component indicators and summary risk score (0-10) were independently associated with significantly increased mortality hazard ratio (HR), adjusted for age, sex, chronic diseases, comorbidity and inflammatory status. Increasing risk categories predicted increasing adjusted HRs (95% CI); low (0-1): reference, moderate (2-3): 1.48 (1.10-2.00), high (4-5): 2.32 (1.52-3.55), very high (6+): 4.97 (2.52-9.77). ENIGMA showed better discriminatory accuracy (C = 0.67, 95% CI = 0.63-0.71) than MNA (C = 0.59, 95% CI = 0.55-0.63), GNRI (C = 0.57, 95% CI = 0.52-0.61), and ESPEN-M (C = 0.52, 95% CI = 0.48-0.56). The predictive accuracy and utility of ENIGMA was supported in the validation cohort (C = 0.68, 95% CI = 0.62-0.74); calibration-at-large, a = 0.00007, p = 0.187; calibration slope = 0.997, 95% CI, 0.997-0.998).

CONCLUSION

The ENIGMA is a validated nutritional prognostic tool that strongly predicts long-term mortality risks and is recommended for use in geriatric outpatient and primary care settings.

Nutritional risk in major abdominal surgery: NURIMAS Liver (DRKS00010923) - protocol of a prospective observational trial to evaluate the prognostic value of different nutritional scores in hepatic surgery

Background

Malnutrition is commonly known as a risk factor in surgical procedures. The nutritional status seems particularly relevant to the clinical outcome of patients undergoing hepatic resection. Thus, identifying affected individuals and taking preventive therapeutic actions before surgery is an important task. However, there are only very few studies, that investigate which existing nutritional assessment score (NAS) is suited best to predict the postoperative outcome in liver surgery.

Objective

Nutritional Risk in Major Abdominal Surgery (NURIMAS) Liver is a prospective observational trial that analyses the predictive value of 12 different NAS for postoperative morbidity and mortality after liver resection.

Methods

After admission to the surgical department of the University Hospital in Heidelberg or the municipal hospital of Karlsruhe, all patients scheduled for elective liver resection will be screened for eligibility. Participants will fill in a questionnaire and undergo a physical examination in order to evaluate nutritional status according to Nutritional Risk Index, Nutritional Risk Screening Score, Subjective Global Assessment, Malnutrition Universal Screening Tool, Mini Nutritional Assessment, Short Nutritional Assessment Questionnaire, Imperial Nutritional Screening System, Imperial Nutritional Screening System II, Nutritional Risk Classification and the ESPEN malnutrition criteria. Postoperative morbidity and mortality will be tracked prospectively throughout the postoperative course. The association of malnutrition according to each score and occurrence of at least one major complication will be analysed using both chi-squared tests and a multivariable logistic regression analysis. Already established risk factors in liver surgery will be added as covariates.

Discussion

NURIMAS Liver is a bicentric, prospective observational trial. The aim of this study is to investigate the predictive value of clinical nutritional assessment scores on postoperative morbidity and mortality after hepatic resection. This is necessary, as only a validated identification of malnourished patients at high risk for postoperative complications, enables targeted preventive action.

Factors associated with the practice of nursing staff sharing information about patients' nutritional status with their colleagues in hospitals

BACKGROUND/OBJECTIVES

Nursing staff have an important role in patients' nutritional care. The aim of this study was to demonstrate how the practice of sharing a patient's nutritional status with colleagues was affected by the nursing staff's attitude, knowledge and their priority to provide nutritional care.

SUBJECTS/METHODS

The participants were 492 nursing staff. We obtained participants' demographic data, the practice of sharing patients' nutritional information and information about participants' knowledge, attitude and priority of providing nutritional care by the questionnaire. We performed partial correlation analyses and linear regression analyses to describe the relationship between the total scores of the practice of sharing patients' nutritional information based on their knowledge, attitude and priority to provide nutritional care.

RESULTS

Among the 492 participants, 396 nursing staff (80.5%) completed the questionnaire and were included in analyses. Mean±s.d. of total score of the 396 participants was 8.4±3.1. Nursing staff shared information when they had a high nutritional knowledge (r=0.36, P<0.01) and attitude (r=0.13, P<0.05); however, their correlation coefficients were low. In the linear regression analyses, job categories (β=-0.28, P<0.01), knowledge (β=0.33, P<0.01) and attitude (β=0.10, P<0.05) were independently associated with the practice of sharing information. Nursing staff's priority to provide nutritional care practice was not significantly associated with the practice of sharing information.

CONCLUSIONS

Knowledge and attitude were independently associated with the practice of sharing patients' nutrition information with colleagues, regardless of their priority to provide nutritional care. An effective approach should be taken to improve the practice of providing nutritional care practice.
