Undernutrition screening survey in 564,063 patients: patients with a positive undernutrition screening score stay in hospital 1.4 d longer

Dietary Food Record Charts and digital photography effectively estimate hospital meal consumption

BACKGROUND & AIMS

Optimal nutritional intake is essential to support nutritional status and improve recovery in hospital patients. To monitor adequate food intake in patients, reliable and accessible methods to quantify patient food intake accurately are needed. The present study aims to compare the accuracy of two methods, Food Record Charts (FRCs) and Digital Photography (DP), in estimating food intake with the gold standard of Weighed Food Records (WFRs).

METHODS

Thirty nurses, healthcare assistants, and researchers participated in a single-blind, prospective study to estimate food consumption using both FRCs and DP for 27 different hospital meals (6 breakfasts, 6 lunches, 6 dinners, and 9 snacks) consisting of 108 different food items. FRCs and DP estimates were compared to WFRs using the average estimations of all participants. Bland-Altman plots were used to identify any discrepancies in the accuracy of food intake estimation.

RESULTS

FRCs overestimated food consumption by 3.2 ± 14.7 % and DP by 4.7 ± 15.8 % compared to WFRs. The Bland-Altman plots showed limited variation. Similar results were found when analyzing energy and protein content subcategories, the consumed amount, food categories, and food consistency. The inter-rater agreement was W = 0.733 (P = 0.000) and W = 0.682 (P = 0.000) for FRCs and DP, respectively.

CONCLUSIONS

FRCs and DP are accurate methods for quantifying food consumption in hospital meals compared to WFRs, with an overestimation of food consumption by less than 5 %.

Improving hospital food and meal provision: a qualitative exploration of nutrition leaders' experiences in implementing change

BACKGROUND

Recently, numerous initiatives have been taken to improve food and meals for hospital inpatients. Research providing in-depth knowledge on leading such improvement initiatives and implementing changes, specifically through facilitation within this multilevel context, is essential. This study aims to explore nutrition leaders' experiences in implementing changes to improve food and meal provision for hospital inpatients, focusing on facilitation activities.

METHOD

This is a qualitative interview study within the social constructivist paradigm. Participants were recruited through professional networks, advertisements, and snowballing. Eighteen semi-structured interviews were conducted individually with participants in leadership roles of food and meal improvement initiatives at Swedish hospitals. The interviews were transcribed verbatim and analysed thematically through an i-PARIHS lens.

RESULTS

Three themes of facilitation activities were identified: 'Building Relationships', 'Placing Food and Meals on the Agenda', and 'Cultivating Skills'. Building relationships involved establishing connections between the service and clinical divisions. Creating common structures and multidisciplinary teamwork enabled collaboration across organisational boundaries. Placing food and meals on the agenda involved both initial and ongoing communication activities, as food and meal tasks were often considered low priority. Cultivating skills encompassed creating learning opportunities for implementing lasting changes, tailored to specific contexts and adopted within everyday practices.

CONCLUSIONS

Collaboration between foodservice and clinical professionals, along with the dissemination of knowledge, appears to be important for implementing changes. Active leadership supports successful implementations by providing structured approaches, including feedback systems, and by contributing to the recognition of improvement initiatives, according to experiences shared during interviews.

[Hospital malnutrition in Argentina: prevalence and nutritional risk prediction in hospitalized adults according to 6 nutritional screening tools (AANEP-2 Study)]

INTRODUCTION

nutritional screening (NS) is crucial for early detection of malnutrition (MN) and prediction of "nutritional risk".

OBJECTIVES

to establish the prevalence of hospital malnutrition by Subjective Global Assessment (SGA) and evaluate the agreement of NS tools and their ability to predict mortality (M), infectious (IC) and non-infectious complications, and prolonged stay (> 11 days).

METHODS

a multicenter, prospective, observational study was conducted. Nutritional status was assessed with SGA and simultaneously measured with Malnutrition Screening Tool (MST), Short Nutritional Assessment Questionnaire (SNAQ), Malnutrition Universal Screening Tool (MUST), Nutrition Risk Screening (NRS-2002), and Mini Nutritional Assessment Short Form (MNA-SF). All methods were classified into three categories for equivalence with SGA. Kappa was used to assess agreement and logistic regression, sensitivity, specificity, and area under the ROC curve for predictive ability.

RESULTS

a total of 1546 patients from 64 hospitals in Argentina were included, 52.6 % male, median age 58 years. According to SGA, hospital malnutrition prevalence was 48.06 % (95 % CI 45.57; 50.55), with 37 % moderately malnourished (B) and 11 % severely malnourished (C). MST showed the best agreement with SGA (k 0.41), and among methods, MST with SNAQ (k 0.52). Adverse outcomes were associated with MN by any method. SGA, MNA-SF, and NRS-2002 had the best predictive ability (ROC area 0.74 to 0.72 for M). IC were the hardest to predict (maximum ROC area 0.62). Sensitivities ranged from 60 to 96 %, and specificities were above 90 % for MN by SGA.

CONCLUSIONS

variations in predictive ability among NS methods do not affect their clinical applicability.

Influencing factors on nutritional knowledge, attitudes, and practices among nursing assistants in nursing homes

BACKGROUND

The nutritional status of older adults requires focused attention. In Chinese nursing homes, nursing assistants are often the primary caregivers responsible for the daily care of older adults, and their knowledge and attitudes toward nutrition play a fundamental role in providing adequate nutritional care. However, research on the knowledge and attitudes of nursing assistants is limited, despite the fact that these factors play a fundamental role in providing adequate nutritional practices.

OBJECTIVE

The aim of this study is to investigate the knowledge, attitudes, and practices (KAP) of nursing assistants in nursing homes and to analyze the influencing factors.

METHOD

This cross-sectional study was conducted from January to September 2023, involving 692 nursing assistants from 76 nursing homes in Shanghai. We used validated Nutrition Knowledge, Attitude, and Practice Questionnaire for nursing assistants.

RESULTS

The findings indicated that the mean scores for nutritional knowledge, attitudes, and practices were 45.07 ± 16.18, 76.22 ± 10.03, and 69.94 ± 21.46, respectively. Notably, the mean score for nutritional knowledge was the lowest, with 66.04% of nursing assistants scored below 50% accuracy. A significant negative correlation was observed between nutritional knowledge and practices (r=-0.194, p < 0.001), while a positive correlation was found between attitudes and practices (r = 0.422, p < 0.001). Key predictors of higher nutritional knowledge included education level (B = 3.907, p < 0.001), whereas skill deficiency (B=-3.714, p = 0.006), years of caring (B=-2.789, p < 0.001) and regular supervision (B=-3.422, p = 0.018) were negatively associated. Positive nutritional attitudes were associated with higher education (B = 2.453, p < 0.001), years of caring (B = 1.177, p < 0.001), and participation in nutrition training (B = 4.138, p < 0.001). Nutritional practices were positively influenced by age (B = 3.068, p = 0.002), participation in nutrition training (B = 11.474, p < 0.001) and regular supervision (B = 14.597, p < 0.001), but negatively affected by insufficient income (B=-3.189, p = 0.030).

CONCLUSION

This study reveals a significant deficiency in nutritional knowledge among nursing assistants in Shanghai's nursing homes, which adversely impacts their nutritional practices. The findings underscore the urgent need for enhanced training programs and to improve the nutritional competencies of nursing assistants. By addressing these gaps through targeted education and consistent supervision, the quality of nutritional care provided to older adults in nursing homes can be substantially improved.

[Nutritional Care in German Hospitals - Results of a Survey Among Physicians]

Malnutrition affects 20-30% of hospitalized patients and is associated with increased morbidity and mortality. Regular screening and multiprofessional nutrition teams are crucial for detection and treatment. The aim of this survey is to assess the nutritional medical care situation in German acute care hospitals.The online survey was conducted between 11/2022 and 08/2023, distributed through medical professional societies, and personalized for chief physicians registered in the German Hospital Registry. The survey is based on an instrument from Fulda University.182 physicians participated in the survey, with 53% indicating that their hospital has a nutrition team, which is most often affiliated with the gastroenterology department. In 88% of nutrition teams, a specialist physician, mostly a gastroenterologist, is involved. Common issues addressed by the nutrition teams include malnutrition, parenteral/enteral nutrition, and the transition process. In hospitals with nutrition teams, 83% conduct regular screening for malnutrition, compared to 47% in hospitals without nutrition teams. The most frequently used screening tool is the NRS-2002. In clinics with nutrition teams, 57% automatically involve the team when screening is positive. In facilities without nutrition teams, standardized procedures are often not possible due to staffing shortages.The study reveals an unequal nutritional medical care situation in German hospitals. Hospitals with nutrition teams screen more frequently for malnutrition. Improved financing and standardization are necessary to optimize the nutritional medical care situation.

Malnutrition risk screening in adult oncology outpatients: An ASPEN systematic review and clinical recommendations

BACKGROUND

Malnutrition screening is not widely practiced in outpatient cancer centers. This review aims to determine the validity of malnutrition screening tools and provide recommendations for clinical use.

METHODS

Studies identified by a systematic review assessed the general validity of screening tools in adult oncology outpatients from five databases through 2022. The American Society for Parenteral and Enteral Nutrition (ASPEN) convened a working group of members from the Academy of Nutrition and Dietetics, Academy of Oncology Nurse and Patient Navigators, American Cancer Society, American Society for Clinical Oncology, American Society for Nutrition, American Society for Radiation Oncology, Association of Cancer Care Centers, and Oncology Nursing Society to answer the following questions: (1) should clinicians screen for malnutrition, (2) which malnutrition screening tools are recommended, and (3) what are the clinical applications for malnutrition risk screening in adult oncology outpatients?

RESULTS

Twenty of 738 studies met the criteria and were reviewed. Six screening tools with specific cut-points demonstrated validity and are recommended, including the Mini Nutritional Assessment (≤23.5), Malnutrition Screening Tool (MST; MST ≥ 2 and patient-led MST ≥ 2), Malnutrition Universal Screening Tool (MUST; MUST ≥ 1 and MUST ≥ 2), Nutrition Risk Screening-2002 (NRS-2002; NRS-2002 ≥ 2 and NRS-2002 ≥ 3), NUTRISCORE ≥ 5, and Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF; PG-SGA SF ≥ 7 and PG-SGA SF ≥ 8).

CONCLUSION

Six screening tools are valid for malnutrition risk identification in oncology ambulatory settings and recommended before treatment initiation and regularly thereafter, depending on treatment course. Research is needed to understand to what extent early diagnosis and management of malnutrition improves the clinical care of oncology patients.

Clinical Impact of Malnutrition According to the Global Leadership Initiative on Malnutrition Criteria Combined With Kidney Dysfunction to Determine Mortality in Inpatients

OBJECTIVE

The clinical impact of malnutrition based on the Global Leadership Initiative on Malnutrition (GLIM) criteria in patients with kidney dysfunction remains poorly understood. This study investigated the usefulness of GLIM criteria for malnutrition in predicting mortality in patients with kidney dysfunction and different clinical renal states, including no kidney disease (NKD), acute kidney injury (AKI), and chronic kidney disease (CKD).

METHODS

This single-center retrospective cohort study included 6,712 patients aged ≥18 admitted between 2018 and 2019. The relationship between the estimated glomerular filtration rate (eGFR) groups, nutritional status based on the GLIM criteria, and the incidence of all-cause mortality was evaluated using a multivariate Cox proportional hazards model. Malnutrition was defined as at least one phenotype (weight loss, low body mass index, or reduced muscle mass) and one etiological criterion (reduced intake/assimilation or disease burden/inflammation).

RESULTS

Multivariate Cox proportional hazards model showed that eGFR ≤29 (vs. eGFR: 60-89, adjusted hazard ratio [HR] = 1.84, 95% confidence interval [CI]: 1.52-2.22), 30-59 (vs. eGFR: 60-89, adjusted HR = 1.40, 95% CI: 1.20-1.64), and ≥90 (vs. eGFR: 60-89, adjusted HR = 1.40, 95% CI: 1.14-1.71), moderate and severe malnutrition (vs. without malnutrition, adjusted HR = 1.38 [1.18-1.62] and 2.18 [1.86-2.54], respectively) were independently associated with the incidence of death. The all-cause mortality rate was higher in patients with malnutrition or eGFR ≤29 (adjusted HR, 3.31; 95% CI: 2.51-4.35) than in patients without malnutrition or eGFR 60-89. Furthermore, moderate and severe malnutrition (vs. no malnutrition) was independently associated with death in patients with NKD, AKI, and CKD.

CONCLUSION

Malnutrition based on the GLIM criteria was associated with increased all-cause mortality in inpatients, and malnutrition combined with kidney dysfunction was associated with a higher risk of mortality. Furthermore, patients with NKD, AKI, and CKD showed an association between malnutrition based on GLIM criteria and mortality.

A Systematic Review of Clinical Practice Guidelines on the Management of Malnutrition in Children with Congenital Heart Disease

Congenital heart disease (CHD) is one of the most common inborn disorders, with a prevalence of 0.8-1.2%. Affected children are often malnourished due to increased dietary requirements. This may lead to severe long-term complications. Several authoritative organizations have published guidelines addressing nutritional intervention in children with CHD. We aimed to systematically assess the consistency of recommendations, the methodological quality of these guidelines, and the quality of evidence supporting each recommendation. PubMed, Embase, the Cochrane Database, World Health Organization Global Index Medicus, and 16 scientific societies' websites were searched for the period until September 2023. The guideline quality was assessed using the AGREE II tool. After screening 765 records, only 2 guidelines published in 2013 and 2022 met our inclusion criteria. The main reason for exclusion was the absence of any system for rating the evidence. The main issues concerned the lack of implementation advice or tools and the lack of criteria to measure the application of guideline recommendations. The included guidelines were of good quality and within specific recommendations, both publications were largely in agreement, and the score for the overall assessment was high (83%). There is a pressing need for comprehensive, multi-threaded guidelines incorporating implementation strategies and methods for the performance assessment of children with malnutrition and CHD.

Relationship between Improvement in Physical Activity and Three Nutritional Assessment Indicators in Patients Admitted to a Convalescent Rehabilitation Ward

We investigated the relationship between three nutritional indicators, the Mini Nutritional Assessment-Short Form (MNA-SF), Geriatric Nutritional Risk Index (GNRI), and Controlling Nutrition Status (CONUT), and physical activity at discharge in patients admitted to convalescent rehabilitation wards. The study included 1601 patients (77 ± 12 years, male 46.2%) discharged from convalescent rehabilitation wards between April 2018 and September 2023. MNA-SF, GNRI, and CONUT scores were obtained on admission. Patients were divided into two groups according to their level of Functional Independence Measure (FIM) walk score at discharge. The walking group (n = 1181, FIM walk score ≥ 5, 76 ± 13 years, male 47.2%) was significantly younger than the wheelchair group (n = 420, 79 ± 12 years, FIM walk score < 5, male 43.8%) and had significantly higher MNA-SF (6.5 ± 2.5 vs. 4.7 ± 2.4) and GNRI (93.1 ± 12.4 vs. 86.7 ± 10.9) scores and significantly lower CONUT (3.1 ± 2.3 vs. 3.9 ± 2.3) scores than the wheelchair group (all p < 0.01). Multivariate logistic regression analysis showed that age, handgrip strength, Functional Oral Intake Scale, and MNA-SF score were independently associated with walking ability at discharge (all p < 0.01). In addition, MNA-SF scores were independently associated with Rehabilitation Effectiveness. These results suggest that nutritional status, particularly MNA-SF scores on admission, is associated with improvement of physical activity at discharge.

Positive health: An integrated quantitative approach in patients with chronic gastrointestinal and hepato-pancreatico-biliary disorders

BACKGROUND

The concept of positive health (PH) supports an integrated approach for patients by taking into account six dimensions of health. This approach is especially relevant for patients with chronic disorders. Chronic gastrointestinal and hepato-pancreatico-biliary (GI-HPB) disorders are among the top-6 of the most prevalent chronically affected organ systems. The impact of chronic GI-HPB disorders on individuals may be disproportionally high because: (1) The affected organ system frequently contributes to a malnourished state; and (2) persons with chronic GI-HPB disorders are often younger than persons with chronic diseases in other organ systems.

AIM

To describe and quantify the dimensions of PH in patients with chronic GI-HPB disorders.

METHODS

Prospective, observational questionnaire study performed between 2019 and 2021 in 235 patients with a chronic GI-HPB disorder attending the Outpatient Department of the Maastricht University Medical Center. Validated questionnaires and data from patient files were used to quantify the six dimensions of PH. Internal consistency was tested with McDonald's Omega. Zero-order Pearson correlations and t-tests were used to assess associations and differences. A P value < 0.05 was considered significant.

RESULTS

The GI-HPB patients scored significantly worse in all dimensions of PH compared to control data or norm scores from the general population. Regarding quality of life, participation and daily functioning, GI-HPB patients scored in the same range as patients with chronic disorders in other organ systems, but depressive symptoms (in 35%) and malnutrition (in 45%) were more frequent in patients with chronic GI-HPB disorders. Intercorrelation scores between the six dimensions were only very weak to weak, forcing us to quantify each domain separately.

CONCLUSION

All six dimensions of PH are impaired in the GI-HPB patients. Malnutrition and depressive symptoms are more prevalent compared to patients with chronic disorders in other organ systems.

Identifying malnutrition risk in hospitalized patients: an analysis of five tools in the light of GLIM criteria

BACKGROUND

The prompt identification of malnutrition among hospitalized patients using the appropriate screening tool is paramount. The objective of our study is to compare the most recommended screening tools concerning the new GLIM criteria for malnutrition in hospitalized patients.

METHODS

In this cross-sectional study, we analyzed the data on 1,397 patients receiving inpatient treatment at Bandırma Training and Research Hospital between August 2022 and May 2023 to assess and compare malnutrition in them. Patients who received inpatient treatment in the internal and surgical clinics of Bandırma Training and Research Hospital. In addition to the GLIM criteria, we used nutritional screening and assessment tools such as NRS-2002, MST, GMS, MUST, and SNAQ. The GLIM criteria were considered the gold standard for the evaluation of sensitivity and specificity. Receiver operating characteristic (ROC) curves for the five screening tools were also used to assess the ability to distinguish malnutrition-risk patients accurately.

RESULTS

The comparison of the performances of different screening tools in detecting malnutrition demonstrated that while the GMS had the highest sensitivity (87.40%), the NRS-2002 had the highest specificity (91.70%). The area under the Curve (AUC) value indicated that the predictive values of the NRS-2002, MST, GMS, and SNAQ were excellent, and the predictive value of the MUST was good (p < 0.001). While the GLIM criteria in particular appear to be an effective tool for detecting malnutrition in hospitalized individuals, other screening tools are also useful in assessing their malnutrition risk.

CONCLUSIONS

We emphasized MST's alignment with GLIM criteria, underscoring the importance of a multidisciplinary approach for early malnutrition diagnosis. Patients at risk of malnutrition can be diagnosed more quickly and accurately with appropriate screening tools and the effectiveness of treatments can be increased.

Access to a pre-sleep protein snack increases daily energy and protein intake in surgical hospitalized patients

BACKGROUND & AIM

In hospitalized patients, daily protein intake remains far below WHO requirements for healthy adults (0.8 g·kg-1·d-1) as well as ESPEN guidelines for patients (1.2-1.5 g·kg-1·d-1). Providing access to a pre-sleep protein dense snack between dinner and going to bed may serve as a great opportunity to increase daily energy and protein intake in hospitalized patients. However, it remains to be assessed whether protein provision prior to sleep effectively increases protein intake, or may reduce food intake throughout the remainder of the day(s). The present study evaluated the impact of giving access to a pre-sleep snack on daily energy and protein intake in patients throughout their hospitalization.

METHODS

Patients admitted to the surgical wards of the Maastricht University Medical Centre+ were randomly allocated to usual care (n = 51) or given access to a pre-sleep snack (n = 50). The pre-sleep snack consisted of 103 g cheese cubes (30 g protein) provided between 7:30 and 9:30 PM, prior to sleep. All food provided and all food consumed was weighed and recorded throughout (2-7 days) hospitalization. Daily energy and protein intake and distribution were calculated. Data were analyzed by independent T-Tests with P < 0.05 considered as statistically significant.

RESULTS

Daily energy intake was higher in the pre-sleep group (1353 ± 424 kcal d-1) when compared to the usual care group (1190 ± 402 kcal·d-1; P = 0.049). Providing patients access to a pre-sleep snack resulted in a 17% (11 ± 9 g) higher daily protein intake (0.81 ± 0.29 g·kg-1·d-1) when compared to the usual care group (0.69 ± 0.28 g·kg-1·d-1; P = 0.045). Protein intake at breakfast, lunch, and dinner did not differ between the pre-sleep and usual care groups (all P > 0.05).

CONCLUSION

Providing access to a pre-sleep protein snack, in the form of protein dense food items such as cheese, represents an effective dietary strategy to increase daily energy and protein intake in hospitalized patients. Patients consuming pre-sleep protein snacks do not compensate by lowering energy or protein intake throughout the remainder of the days. Pre-sleep protein dense food provision should be implemented in hospital food logistics to improve the nutritional intake of patients.

Challenges in identifying malnutrition in obesity; An overview of the state of the art and directions for future research

(Protein-energy) malnutrition in individuals living with obesity presents complex diagnostic challenges due to the distinctive physiological characteristics of obesity. This narrative review critically examines the identification of malnutrition within the population with obesity, distinguishing malnutrition in obesity from related conditions such as sarcopenic obesity. While noting some shared features, the review highlights key differences between these conditions. The review also highlights the limitations of current malnutrition screening tools, which are not designed for individuals living with obesity. These tools primarily rely on anthropometric measurements, neglecting (among others) nutrient intake assessment, which hinders accurate malnutrition detection. Additionally, this review discusses limitations in existing diagnostic criteria, including the Global Leadership Initiative on Malnutrition (GLIM) criteria, when applied to individuals living with obesity. Challenges include the identification of appropriate cut-off values for phenotypic criteria (unintentional weight loss, low body mass index and muscle mass) and aetiological criteria such as reduced food intake and inflammation for the population with obesity. Overall, this review emphasises the need for modified screening tools and diagnostic criteria to recognise and assess malnutrition in obesity, leading to improved clinical outcomes and overall wellbeing.

Dietary Provision, GLIM-Defined Malnutrition and Their Association with Clinical Outcome: Results from the First Decade of nutritionDay in China

Malnutrition is a common and serious issue that worsens patient outcomes. The effects of dietary provision on the clinical outcomes of patients of different nutritional status needs to be verified. This study aimed to identify dietary provision in patients with eaten quantities of meal consumption and investigate the effects of dietary provision and different nutritional statuses defined by the GLIM criteria on clinical outcomes based on data from the nutritionDay surveys in China. A total of 5821 adult in-patients from 2010 to 2020 were included in this study's descriptive and Cox regression analyses. Rehabilitation and home discharge of 30-day outcomes were considered a good outcome. The prevalence of malnutrition defined by the GLIM criteria was 22.8%. On nutritionDay, 51.8% of all patients received dietary provisions, including hospital food and a special diet. In multivariable models adjusting for other variables, the patients receiving dietary provision had a nearly 1.5 higher chance of a good 30-day outcome than those who did not. Malnourished patients receiving dietary provision had a 1.58 (95% CI [1.36-1.83], p < 0.001) higher chance of having a good 30-day outcome and had a shortened length of hospital stay after nutritionDay (median: 7 days, 95% CI [6-8]) compared to those not receiving dietary provision (median: 11 days, 95% CI [10-13]). These results highlight the potential impacts of the dietary provision and nutritional status of in-patients on follow-up outcomes and provide knowledge on implementing targeted nutrition care.

Validity and applicability of the global leadership initiative on malnutrition criteria in non-dialysis patients with chronic kidney disease

Introduction

There are no standardized assessment criteria for selecting nutritional risk screening tools or indicators to assess reduced muscle mass (RMM) in the Global Leadership Initiative on Malnutrition (GLIM) criteria. We aimed to compare the consistency of different GLIM criteria with Subjective Global Assessment (SGA) and protein-energy wasting (PEW).

Methods

In this study, nutritional risk screening 2002 first four questions (NRS-2002-4Q), Nutritional Risk Screening 2002 (NRS-2002), Malnutrition Universal Screening Tool (MUST), and Mini-Nutritional Assessment Short-Form (MNA-SF) tools were used as the first step of nutritional risk screening for the GLIM. The RMM is expressed using different metrics. The SGA and PEW were used to diagnose patients and classify them as malnourished and non-malnourished. Kappa (κ) tests were used to compare the concordance between the SGA, PEW, and GLIM of each combination of screening tools.

Results

A total of 157 patients were included. Patients with Chronic kidney disease (CKD) stage 1-3 accounted for a large proportion (79.0%). The prevalence rates of malnutrition diagnosed using the SGA and PEW were 18.5% and 19.7%, respectively. The prevalence of GLIM-diagnosed malnutrition ranges from 5.1% to 37.6%, depending on the different screening methods for nutritional risk and the different indicators denoting RMM. The SGA was moderately consistent with the PEW (κ = 0.423, p < 0.001). The consistency among the GLIM, SGA, and PEW was generally low. Using the NRS-2002-4Q to screen for nutritional risk, GLIM had the best agreement with SGA and PEW when skeletal muscle index (SMI), fat-free mass index (FFMI), and hand grip strength (HGS) indicated a reduction in muscle mass (SGA: κ = 0.464, 95% CI 0.28-0.65; PEW: κ = 0.306, 95% CI 0.12-0.49).

Conclusion

The concordance between the GLIM criteria and the SGA and PEW depended on the screening tool used in the GLIM process. The inclusion of RMM in the GLIM framework is important. The addition of HGS could further improve the performance of the GLIM standard compared to the use of body composition measurements.

Individualized threshold of the involuntary weight loss in prognostic assessment of cancer

BACKGROUND

Involuntary weight loss (WL) is a common symptom in cancer patients and is associated with poor outcomes. However, there is no standardized definition of WL, and it is unclear what magnitude of weight loss should be considered significant for prognostic purposes. This study aimed to determine an individualized threshold for WL that can be used for prognostic assessment in cancer patients.

METHODS

Univariate and multivariate analyses of overall survival (OS) were performed using Cox proportional hazard models. The Kaplan-Meier method was performed to estimate the survival distribution of different WL levels. Logistic regression analysis was used to determine the relationship between WL and 90-day outcomes. Restricted cubic splines with three knots were used to examine the effects of WL on survival under different body mass index (BMI) conditions.

RESULTS

Among the 8806 enrolled patients with cancer, median survival time declined as WL increased, from 25.1 to 20.1, 17.8 and 16.4 months at <2%, 2-5%, 5-10% and ≥10% WL, respectively (P < 0.001). Multivariate adjusted Cox regression analysis showed that the risk of adverse prognosis increased by 18.1% based on the SD of WL (5.45 U) (HR: 1.181, 95% CI: 1.144-1.219, P < 0.001). Similarly, categorical WL was independently associated with OS in patients with cancer. With the worsening of WL, the risk of a poor prognosis in patients increases stepwise. Compared with <2% WL, all-cause mortalities were 15.1%, 37% and 64.2% higher in 2-5%, 5-10%, and ≥10% WL, respectively. WL can effectively stratify the prognosis of both overall and site-specific cancers. The clinical prognostic thresholds for WL based on different BMI levels were 4.21% (underweight), 5.03% (normal), 6.33% (overweight), and 7.60% (obese). Multivariate logistic regression analysis showed that WL was independently associated with 90-day outcomes in patients with cancer. Compared with patients with <2% WL, those with ≥10% WL had more than twice the risk of 90-day outcomes (OR: 3.277, 95% CI: 2.287-4.694, P < 0.001). Systemic inflammation was a cause of WL deterioration. WL mediates 6.3-10.3% of the overall association between systemic inflammation and poor prognoses in patients with cancer.

CONCLUSIONS

An individualized threshold for WL based on baseline BMI can be used for prognostic assessment in cancer patients. WL and BMI should be evaluated simultaneously in treatment decision-making, nutritional intervention, and prognosis discussions of patients with cancer.

Risk of malnutrition assessment in hospitalised adults: A scoping review of existing instruments

AIMS AND OBJECTIVES

The aim of this study was to find tools for screening the risk of malnutrition in adult hospitalised patients, evaluate their key characteristics including selected psychometric properties and propose the most appropriate tools for nursing practice.

BACKGROUND

A large number of existing tools for nutritional screening make it difficult to be aware of all the possibilities and especially to select the optimal tool.

DESIGN

The research methodology was designed as secondary research using a scoping review search to map and compare existing tools for assessing the risk of malnutrition in hospitalised adults.

METHODS

The analysis focused on the selected psychometric properties of the instruments (sensitivity, specificity, positive and negative predictive value) and key characteristics relevant to the selection of an appropriate instrument. This study follows the PRISMA-ScR Checklist.

RESULTS

The review included 27 publications containing 17 tools. The best sensitivity (57%-100%) and specificity (76%-96%) were achieved by the Malnutrition Universal Screening Tool (MUST) and the Nutritional Risk Screening 2002 (NRS 2002). Minimal Eating Observation and Nutrition Form-Version II (MEONF-II) has solid sensitivity (up to 73%), specificity (88%) and high positive predictive values (81%-82%).

CONCLUSIONS

The MUST, NRS 2002 and MEONF-II showed satisfactory psychometric properties. MEONF-II and MUST are able to assess risk without weighing the patient. The Hand Grip Strength (HGS) assessment can be recommended to detect reductions in muscle strength.

RELEVANCE TO CLINICAL PRACTICE

We recommend the MUST, NRS 2002 and MEONF-II tools for use in clinical practice, as they have the best psychometric properties and are user-friendly. The HGS, which proved to be related to the length of hospital stay (LOS) and used as an indicator of protein-energy malnutrition in obese patients, may be a useful complementary tool. For nursing practice, we recommend selecting a tool with respect to the specifics of a particular workplace.

Development and evaluation of a Massive Open Online Course (MOOC) for healthcare professionals on malnutrition in older adults

BACKGROUND

Education about malnutrition in older adults is often lacking in the curricula of healthcare professionals. Massive open online courses (MOOCs) are an innovative form of education that can potentially improve the knowledge of healthcare professionals.

OBJECTIVES

(1) to describe the development of a MOOC on malnutrition in older adults and (2) to evaluate the MOOC on the basis of knowledge gained.

DESIGN

The MOOC was developed by following a structured approach. For the evaluation of the MOOC, a cross-sectional descriptive study was conducted.

PARTICIPANTS

Overall, 1288 nurses, dietitians, medical doctors and other healthcare professionals participated in the evaluation study.

METHODS

After performing a comprehensive literature review, two dietitians specialised in geriatrics developed a summary of potentially important content of the MOOC. Nine European malnutrition experts from different professional areas were then asked to contribute their expertise. The specific MOOC content was developed based on the recent literature and evidence-based guidelines. For the evaluation of the MOOC, a questionnaire with 41 questions was developed. Results were analysed using descriptive statistics and chi-square tests.

RESULTS

The final MOOC consists of five modules with 15 learning videos and supplementary material. The percentage of persons with good malnutrition knowledge increased from 76.1 % to 89.9 % (p < 0.001), while the percentage of persons with fair or little malnutrition knowledge decreased (p < 0.001). The course significantly improved the participants' knowledge of specific malnutrition topics, namely, methods and instruments to determine the nutritional status of older people, interventions to improve oral intake, medical nutrition and multidisciplinary cooperation (p < 0.001). Overall, 91.5 % of the participants rated the quality of the course as very good or good.

CONCLUSION

MOOCs may be an effective tool that can be used to improve knowledge in healthcare professionals. This provides new opportunities for successful multidisciplinary malnutrition management in clinical practice.

Evaluation of a new digital pediatric malnutrition risk screening tool for hospitalized children with congenital heart disease

BACKGROUND

In a cohort of hospitalized children with congenital heart disease (CHD), a new digital pediatric malnutrition screening tool as a mobile application was validated, and its effectiveness and clinical value were determined as a prospective study.

METHODS AND RESULTS

Children with CHD (n = 1125) were screened for malnutrition risk. The incidence of risk and the differences among various age groups and types of CHD were characterized. The optimal threshold for the tool to determine if there is a risk of malnutrition is score 2, while the Youden index was 79.1%, and the sensitivity and specificity were 91.2% and 87.9%, respectively. Based on such criterion, 351 children were at risk of malnutrition accounting for 31.20% of the total. Compared with the non-malnutritional risk group, the median age for the group at risk for malnutrition was younger (8.641 months [4.8, 23.1] vs. 31.589 months [12.4, 54.3], P < 0.01), and the length of stay was longer (12.000 [8.0, 17.0] vs. (8.420 [5.0, 12.0], P < 0.01]. There were significant differences in malnutrition risk among different age groups (χ2 = 144.933, P < 0.01), and children under one year of age exhibited the highest risk for malnutrition and more extended hospital stay (H = 78.085, P < 0.01). The risk of malnutrition among children with cyanotic CHD was higher than in those with non-cyanotic CHD (χ2 = 104.384, P < 0.01).

CONCLUSIONS

The new digital pediatric malnutrition screening tool showed high sensitivity and specificity in children with CHD. The tool indicated that the malnutrition risk for young children and children with cyanotic or Bethesda moderate and complex CHD was higher, and the hospitalization time was longer than in the non-risk group. The tool provides a rational approach to targeted nutrition intervention and support and may improve clinical outcomes.

Intervention-related, contextual and personal factors affecting the implementation of an evidence-based digital system for prevention and treatment of malnutrition in elderly institutionalized patients: a qualitative study

BACKGROUND

Malnutrition in elderly institutionalized patients is a significant challenge associated with adverse health outcomes. The 'MyFood' decision support system was designed to prevent and treat malnutrition and has previously been studied in a hospital setting. The aim of this study was to explore the experiences of nursing staff regarding the implementation of MyFood in settings treating elderly patients.

METHODS

The study was conducted in two settings treating elderly patients in Norway. Nursing staff received training in how to follow-up patients with MyFood. Qualitative interviews were conducted with 12 nursing staff. The Consolidated Framework for Implementation Research (CFIR) was used to guide the data collection and the thematic data analysis.

RESULTS

The implementation of a digital decision support system to prevent and treat malnutrition into settings treating elderly patients was found to be affected by intervention-related, contextual, and personal factors. Although nursing staff experienced several advantages, the leadership engagement was low and hampered the implementation.

CONCLUSION

Nursing staff experienced several advantages with implementing a digital decision support system for the prevention and treatment of malnutrition in institutionalized elderly patients, including quality improvements and time savings. The results indicate that the leadership engagement was weak and that some nursing staff experienced low self-efficacy in digital competence. Future improvements include increasing the level of training, using MyFood throughout the patient course and involving the patient's next-of-kin.

Good nutrition across the lifespan is foundational for healthy aging and sustainable development

Ensuring healthy lives and promoting wellbeing across the age spectrum are essential to sustainable development. Nutrition is at the heart of the World Health Organization (WHO) Sustainable Development Goals, particularly for Sustainable Development Goal 2/Subgoal 2, which is to End all forms of malnutrition by 2030. This subgoal addresses people of all ages, including targeted groups like young children and older adults. In recent decades, there have been marked advances in the tools and methods used to screen for risk of malnutrition and to conduct nutritional assessments. There have also been innovations in nutritional interventions and outcome measures related to malnutrition. What has been less common is research on how nutritional interventions can impact healthy aging. Our Perspective article thus takes a life-course approach to consider what is needed to address risk of malnutrition and why, and to examine how good nutrition across the lifespan can contribute to healthy aging. We discuss broad-ranging yet interdependent ways to improve nutritional status worldwide-development of nutritional programs and policies, incorporation of the best nutrition-care tools and methods into practice, provision of professional training for quality nutritional care, and monitoring health and economic benefits of such changes. Taken together, our Perspective aims to (i) identify current challenges to meeting these ideals of nutritional care, and to (ii) discover enabling strategies for the improvement of nutrition care across the lifespan. In harmony with the WHO goal of sustainable development, we underscore roles of nutrition to foster healthy human development and healthy aging worldwide.

Nutritional Status and Sarcopenia in Nursing Home Residents: A Cross-Sectional Study

OBJECTIVE

This study aimed to assess the nutritional status and sarcopenia in older people living in nursing homes.

METHODS

This cross-sectional study enrolled 386 older adults in nursing homes in Hunan Province, China. Assessments included the Mini Nutritional Assessment Short Form for nutrition risk, Dietary Diversity Score for dietary diversity and Mini Mental State Examination for cognitive status. Sociodemographic (e.g., age, sex and educational level), health-related characteristics (e.g., food intake, self-care status and medication), body composition (e.g., body mass index [BMI], protein, body fat mass [BFM], percent body fat [PBF], skeletal muscle index [SMI] and total body water [TBW]) and anthropometric parameters data (e.g., calf circumference [CC], upper arm circumference [UAC], handgrip and gait speed) were also collected. Malnutrition and their associated risk were analyzed by multivariable Poisson regression analysis.

RESULTS

In total, 32.4% of participants (n = 125) were at risk of malnutrition and 49.7% (n = 192) suffered from sarcopenia. Nutritional status was positively associated with age (risk ratio [RR] = 1.03), sarcopenia (RR = 1.88), tooth loss affecting food intake (RR = 1.45), low self-care status (RR = 1.82) and moderate/inadequate dietary diversity (RR = 2.04) and negatively associated with one child (RR = 0.27), BMI (RR = 0.82), protein (RR = 0.76), BFM (RR = 0.91), PBF (RR = 0.94), SMI (RR = 0.65), TBW (RR = 0.94), CC (RR = 0.89) and UAC (RR = 0.86).

CONCLUSIONS

Age, number of children, sarcopenia, food intake, self-care status, dietary diversity and body composition were associated with malnutrition among nursing home residents. For vulnerable groups, researchers should focus on raising the body composition indicators, such as BMI, protein, BFM, SMI and TBW and measuring CC and UAC for initial screening.

Implementing a Machine Learning Screening Tool for Malnutrition: Insights from Qualitative Research Applicable to Other ML-Based CDSS (Preprint)

BACKGROUND

Machine learning (ML)-based clinical decision support systems (CDSS) are popular in clinical practice settings but are often criticized for being limited in usability, interpretability, and effectiveness. Evaluating the implementation of ML-based CDSS is critical to ensure CDSS is acceptable and useful to clinicians and helps them deliver high-quality health care. Malnutrition is a common and underdiagnosed condition among hospital patients, which can have serious adverse impacts. Early identification and treatment of malnutrition are important.

OBJECTIVE

This study aims to evaluate the implementation of an ML tool, Malnutrition Universal Screening Tool (MUST)-Plus, that predicts hospital patients at high risk for malnutrition and identify best implementation practices applicable to this and other ML-based CDSS.

METHODS

We conducted a qualitative postimplementation evaluation using in-depth interviews with registered dietitians (RDs) who use MUST-Plus output in their everyday work. After coding the data, we mapped emergent themes onto select domains of the nonadoption, abandonment, scale-up, spread, and sustainability (NASSS) framework.

RESULTS

We interviewed 17 of the 24 RDs approached (71%), representing 37% of those who use MUST-Plus output. Several themes emerged: (1) enhancements to the tool were made to improve accuracy and usability; (2) MUST-Plus helped identify patients that would not otherwise be seen; perceived usefulness was highest in the original site; (3) perceived accuracy varied by respondent and site; (4) RDs valued autonomy in prioritizing patients; (5) depth of tool understanding varied by hospital and level; (6) MUST-Plus was integrated into workflows and electronic health records; and (7) RDs expressed a desire to eventually have 1 automated screener.

CONCLUSIONS

Our findings suggest that continuous involvement of stakeholders at new sites given staff turnover is vital to ensure buy-in. Qualitative research can help identify the potential bias of ML tools and should be widely used to ensure health equity. Ongoing collaboration among CDSS developers, data scientists, and clinical providers may help refine CDSS for optimal use and improve the acceptability of CDSS in the clinical context.

Validation of the Visual/Verbal Analogue Scale of Food Ingesta (Ingesta-VVAS) in Oncology Patients Undergoing Chemotherapy

This study aimed to: (1) externally validate the Visual/Verbal Analogue Scale of food ingesta (ingesta-VVAS) that previously showed good discrimination between oncology patients who ingest more or less energy than required; (2) explore the discriminative properties of other questions. Dietitians performed 322 interviews in 206 adult oncology patients undergoing chemotherapy in two Dutch hospitals, including a 24-h dietary recall, assessment of the ingesta-VVAS and 12 additional questions related to reduced food intake. The ingesta-VVAS score was linearly associated with energy intake as % of Total Energy Expenditure (TEE) (standardized beta = 0.39, p < 0.001), with no differences between groups based on use of oral nutritional supplements, body mass index, in/outpatient setting or sex. The accuracy of the ingesta-VVAS score to predict low energy intake (<75% of TEE) was poor (Area Under the Receiver Operating Characteristic curve (AUC) = 0.668, 95% CI 0.603−0.733). The optimal multivariate model included the ingesta-VVAS score and a question on ‘feeling sick’ (AUC = 0.680, 95% CI 0.615−0.746). In conclusion, in our study the ingesta-VVAS discriminates poorly between oncology patients undergoing chemotherapy who ingest more or less energy than required. Adding a question on feeling sick only slightly improved model performance. Further external validation is warranted.

Attention, Praxis, and Reasoning Are Associated with Risk of Undernutrition in Older People with Cognitive Impairment

BACKGROUND

Dementia is a risk factor for undernutrition. However, it is not clear if specific cognitive deficits have a higher risk of undernutrition and how much appetite/nutritional problems and caregiver stress mediate this association.

OBJECTIVE

To evaluate the relationship between nutritional status and severity of global and function-specific scores of cognitive dysfunctions, and to which extent this association is mediated by appetite/nutritional problems and caregiver stress.

METHODS

Cross-sectional analysis of the ReGAl study data, including 761 older adults attending a Memory Clinic. Nutritional status was evaluated with Mini Nutritional Assessment (MNA). The relationship between scores at neuro-cognitive tests and risk of undernutrition was evaluated using logistic regression models adjusted for potential confounders. To allow comparison between different tests, all scores were standardized. Mediation analysis was used to evaluate how much appetite/nutritional problems and caregiver stress mediate this association.

RESULTS

Mean age was 77 years (SD: 9), 37.3% were women. Exploring different cognitive domains, a stronger association was documented for attentive matrices (OR:0.49, 95% CI: 0.34-0.72), the figure copy test (OR:0.63, 95% CI: 0.45-0.88), and the verbal judgement test (OR:0.61, 95% CI: 0.42-0.91). The proportion of the effect of cognition (MMSE) on nutritional status mediated by caregiver distress was 9.5% (95% CI: 0.002-0.27), the proportion mediated by appetite/nutritional problems was 11% (95% CI: -4.8-3.18).

CONCLUSION

Risk of undernutrition is associated to cognitive decline; a stronger association was observed for attention, praxis, and reasoning. Caregiver distress is a mediator of this association. This information should be considered in the management plans of this population.

Interprofessional Treatment of Malnutrition and Sarcopenia by Dietitians and Physiotherapists: Exploring Attitudes, Interprofessional Identity, Facilitators, Barriers, and Occurrence

Purpose

Malnutrition and sarcopenia require dietetic and physiotherapy interventions. In this study, we aimed to compare interprofessional identity of dietitians and physiotherapists, as well as attitudes towards, facilitators and barriers for, and occurrence of interprofessional treatment of malnutrition and sarcopenia by both professions.

Methods

A cross-sectional online survey was distributed from December 4, 2021 until January 31, 2022 through an international online network platform for professionals (LinkedIn). Practitioners working as dietitian or physiotherapist in a healthcare setting were eligible for participation. Outcome measures concerned perceptions regarding shared problem domains, interprofessional treatment, attitudes towards interprofessional treatment, interprofessional identity, facilitators, and barriers. A Chi²-test, Mann–Whitney U-test, and Spearman’s Rho correlation were calculated.

Results

Data from 53 physiotherapists and 48 dietitians were included. Malnutrition is considered a shared problem domain by both professions (U = 1248.000; p = 0.858). While sarcopenia is treated by both professions (U = 1260.000; p = 0.927), physiotherapists consider sarcopenia more often a shared problem domain compared to dietitians (U = 1003.000; p = 0.044). Attitudes towards interprofessional treatment were mostly positive (73%, n = 35 and 87%, n = 46 respectively). Interprofessional identity of dietitians was lower compared to physiotherapists (median = 4.0 versus median = 4.3 respectively; U = 875.000, p = 0.007). This was explained by lower interprofessional belonging (median = 4.0 versus median = 4.8 respectively; U = 771.000, p < 0.001) and lower interprofessional commitment (median = 4.0 versus median = 4.3 respectively; U = 942.500, p = 0.023). Interprofessional identity was correlated with efficient means of communication (r = 0.30, p = 0.003) and bureaucracy (r = −0.21, p = 0.034). Other barriers reported included available time, financial compensation, interprofessional knowledge, and obtaining extra care. Most reported facilitators concerned role clarity, clarity of expertise, and willingness of others to collaborate.

Conclusion

Dietitians and physiotherapists have different interprofessional identities, but both are advocates of interprofessional treatment. Both professions mostly treat malnutrition and sarcopenia individually and have different perceptions regarding sarcopenia as shared problem domain. Facilitators were mainly related to clarity and commitment while barriers were mainly related to resources.

Higher red cell distribution width and poorer hospitalization-related outcomes in elderly patients

BACKGROUND

Red cell distribution width (RDW), an index for variation of red blood cell (RBC) size, has been proposed as a potential marker for poorer outcomes in several aging-related diseases and conditions. We tested whether greater variability of RBC size, presented as a higher RDW value, predicts poor prognoses among hospitalized patients over 60 years old.

METHODS

We retrospectively collected data from older hospitalized patients aged ≥60 years between January 2013 to December 2017 at Sutter Health, a large integrated health system in Northern California. The RDW was measured during hospital admission and categorized with 1% intervals (≤13.9, 14.0-14.9, 15.0-15.9, 16.0-16.9, 17.0-17.9 and ≥18.0%). The primary outcome was the rate of in-hospital mortality and secondary outcomes included 30-day re-admission rate and length of hospital stay (in days).

RESULTS

A total of 167,292 admissions from 94,617 patients were included. The overall in-hospital mortality rate was 6.3%. As the RDW value increased, the rate of in-hospital mortality gradually increased from 2.7% for the lowest RDW category to 12.2% in the highest category (p-trend <0.001). The overall 30-day re-admission rate after discharge was 12.5% and the rate of 30-day re-admission also increased with increasing RDW categories (7.4% in the lowest group vs. 15.8% in the highest group, p-trend <0.001). Patients with the highest RDW values at admission stayed 1.5-2.0 times longer in the hospital than patients with lower RDW values who were admitted for the same causes.

CONCLUSIONS

Greater variability of RBC size is significantly associated with worse prognosis in hospitalized elderly patients, indicating higher mortality, greater risk of early re-admission, and longer hospital stay days. Risk stratification strategies for hospitalized elderly should include RDW value.

Impact of a surgical ward breakfast buffet on nutritional intake in postoperative patients: A prospective cohort pilot study

BACKGROUND

An early return to normal intake and early mobilization enhances postoperative recovery. However, one out of six surgical patients is undernourished during hospitalization and approximately half of the patients eat 50% or less of the food provided to them. We assessed the use of newly introduced breakfast buffets in two wards for gastrointestinal and oncological surgery and determined the impact on postoperative protein and energy intake.

METHODS

A prospective pilot cohort study was conducted to assess the impact of the introduction of breakfast buffets in two surgical wards. Adult patients had the opportunity to choose between an attractive breakfast buffet and regular bedside breakfast service. Primary outcomes were protein and energy intake during breakfast. We asked patients to report the type of breakfast service and breakfast intake in a diary over a seven-day period. Prognostic factors were used during multivariable regression analysis.

RESULTS

A total of 77 patients were included. The median percentage of buffet use per patient during the seven-day study period was 50% (IQR 0-83). Mean protein intake was 14.7 g (SD 8.4) and mean energy intake 332.3 kcal (SD 156.9). Predictors for higher protein intake included the use of the breakfast buffet (β = 0.06, p = 0.01) and patient weight (β = 0.13, p = 0.01). Both use of the breakfast buffet (β = 1.00, p = 0.02) and Delirium Observation Scale scores (β = -246.29, p = 0.02) were related to higher energy intake.

CONCLUSION

Introduction of a breakfast buffet on a surgical ward was associated with higher protein and energy intake and it could be a promising approach to optimizing such intake in surgical patients. Large, prospective and preferably randomized studies should confirm these findings.

PG-SGA SF in nutrition assessment and survival prediction for elderly patients with cancer

Background

This study was sought to report the prevalence of malnutrition in elderly patients with cancer. Validate the predictive value of the nutritional assessment tool (Patient-Generated Subjective Global Assessment Short Form, PG-SGA SF) for clinical outcomes and assist the therapeutic decision.

Methods

This is a secondary analysis of a multicentric, observational cohort study. Elderly patients with cancer older than 65 years were enrolled after the first admission. Nutritional status was identified using the PG-SGA SF.

Results

Of the 2724 elderly patients included in the analysis, 65.27% of patients were male (n = 1778); the mean age was 71.00 ± 5.36 years. 31.5% of patients were considered malnourished according to PG-SGA SF. In multivariate analysis, malnutrition(PG-SGA SF > 5) was significantly associated with worse OS (HR: 1.47,95%CI:1.29–1.68), affects the quality of life, and was related to more frequent nutrition impact symptoms. During a median follow-up of 4.5 years, 1176 death occurred. The mortality risk was 41.10% for malnutrition during the first 12 months and led to a rate of 323.98 events per-1000-patient-years. All nutritional assessment tools were correlated with each other (PG-SGA SF vs. PG-SGA: r = 0.98; PG-SGA SF vs. GLIM[Global Leadership Initiative on Malnutrition]: r = 0.48, all P < 0.05). PG-SGA SF and PG-SGA performed similarly to predict mortality but better than GLIM. PG-SGA SF improves the predictive ability of the TNM classification system for mortality in elderly patients with cancer, including distinguishing patients’ prognoses and directing immunotherapy.

Conclusions

The nutritional status as measured by PG-SGA SF which is a prognostic factor for OS in elderly cancer patients and could improve the prognostic model of TNM.

The economic cost of not coding disease-related malnutrition: A study in cancer inpatients

BACKGROUND & AIMS

Disease-related malnutrition (DRM) coding rate is usually low in hospitalised patients. The objective of our study was to estimate the percentage of correct DRM coding in cancer inpatients and to calculate the economic losses caused by such lack of coding.

METHODS

This was an observational, prospective study that was conducted in patients hospitalised in the Medical Oncology Unit of our hospital. A nutritional assessment was performed through subjective global assessment (SGA). The all patient refined-diagnosis related group (APR-DRG) weights were obtained at the moment of discharge; moreover, recalculation was done after including the diagnosis of malnutrition in the medical record of those patients in whom it had not been initially coded. The associated cost reimbursement were calculated based on the weight before and after revising the diagnosis of DRM.

RESULTS

A total of 266 patients were evaluated. From them, 220 (82.7%) suffered from DRM according to the SGA. In 137 (51.5%) of these patients, diagnosis was coded, as opposed to 83 (31.2%) cases (33 subjects with moderate and 50 with severe DRM) in whom it was not coded. The sum of the APR-DRG weights before revising the diagnosis of malnutrition was 343.4 points (mean: 1.29 ± 0.89). Whereas, after revising the diagnosis, it increased up to 384.3 (1.44 ± 0.96). The total cost reimbursement for the hospital before revising the diagnosis of malnutrition was 1,607,861.21€ and after revision it increased up to 1,799,199.69€, which means that 191,338.48€ were not reimbursed to the hospital due to the lack of coding of malnutrition. The cost reimbursement for each admission increased an average of 719.32€.

CONCLUSION

The prevalence of DRM in cancer inpatients is high. Nevertheless, the diagnosis is not coded in one third of patients, which results in important economic losses for the hospitals.

Malnutrition and Inadequate Eating Behaviour during Hospital Stay in Geriatrics-An Explorative Analyses of NutritionDay Data in Two Hospitals

(1) Background: Malnutrition in hospitalized patients is prevalent worldwide, but the severity of the issue is often underestimated by practitioners. The purpose of this study is to investigate the prevalence of malnutrition and inadequate eating behaviour in a geriatric sample. (2) Methods: Two hospitals participated with six wards on nutritionDay in 2017, 2018 and 2019. Nutritional status, food intake, and nutritional interventions were analyzed for all patients ≥ 65 years (n = 156), using the official nutritionDay questionnaires. Malnutrition risk is identified by Malnutrition Universal Screening Tool (MUST), malnutrition by the ESPEN criteria (European Society of Clinical Nutrition and Metabolism). (3) Results: According to MUST (n = 136) 16.9% (n = 23) were at medium risk of malnutrition, 33.8% (n = 46) at high risk of malnutrition, 28.1% (n = 38) were malnourished. Overall, 62.8% (n = 98) showed an inadequate eating behaviour during hospital stay. Moreover, patients with inadequate nutrition had significantly worse self-reported health statuses (p = 0.001; r = -0.276), were less able to walk on nutritionDay (p = 0.002; r = -0.255), had eaten little in the week before admission to hospital (p < 0.001; r = -0.313), and had an increased length of stay (p = 0.036; r = -0.174). (4) Conclusion: To identify malnourished patients is a significant barrier for practitioners seeking to administer specific, tailored interventions. Malnutrition screening protocols must be improved, just as nutrition monitoring in general.

Malnutrition Universal Screening Tool and Patient-Generated Subjective Global Assessment Short Form and their predictive validity in hospitalized patients

BACKGROUND AND AIMS

Malnutrition screening is a first step in the nutrition care process for hospitalized patients, to identify those at risk of malnutrition and associated worse outcome, preceding further assessment and intervention. Frequently used malnutrition screening tools including the Malnutrition Universal Screening Tool (MUST) mainly screen for characteristics of malnutrition, while the Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF) additionally includes risk factors for development of malnutrition, yielding a higher percentage of patients at risk. To investigate whether this translates into higher risk of worse outcome, we aimed to determine the predictive validity of MUST and PG-SGA SF for prolonged hospitalization >8 days, readmission, and mortality <6 months after hospital discharge.

METHODS

In this observational study, MUST was performed according to university hospital protocol. Additional screening using PG-SGA SF was performed within 24 h of hospital admission (high risk: MUST ≥ 2, PG_SGA SF ≥ 9). Associations of MUST and PG-SGA SF with outcomes were analyzed by logistic- and Cox PH-regression.

RESULTS

Of 430 patients analyzed (age 58 ± 16 years, 53% male, BMI 26.9 ± 5.5 kg/m²), MUST and PG-SGA SF identified 32 and 80 at high risk, respectively. One-hundred-eight patients had prolonged hospitalization, 109 were readmitted and 20 died. High risk by MUST was associated with mortality (HR = 3.9; 95% CI 1.3-12.2, P = 0.02), but not with other endpoints. High risk by PG-SGA SF was associated with prolonged hospitalization (OR = 2.5; 95% CI 1.3-5.0, P = 0.009), readmission (HR = 1.9; 95% CI 1.1-3.2, P = 0.03), and mortality (HR = 34.8; 95% CI 4.2-289.3, P = 0.001), independent of age, sex, hospital ward and previous hospitalization <6 months. In the 363/430 patients classified as low risk by MUST, high risk by PG-SGA SF was independently associated with higher risk of readmission (HR = 1.9; 95% CI 1.0-3.5, P = 0.04) and mortality (HR = 19.5; 95% CI 2.0-189.4, P = 0.01).

CONCLUSIONS

Whereas high malnutrition risk by MUST was only associated with mortality, PG-SGA SF was associated with higher risk of prolonged hospitalization, readmission, and mortality. In patients considered as low risk by MUST, high malnutrition risk by PG-SGA SF was also predictive of worse outcome. Our findings support the use of PG-SGA SF in routine care to identify patients at risk of malnutrition and worse outcome, and enable proactive interventions.

Short Nutritional Assessment Questionnaire as a predictor of undernutrition in cancer patients receiving outpatient chemotherapy: A retrospective study

PURPOSE

The purpose of this retrospective study was to verify whether the revised Short Nutritional Assessment Questionnaire© (SNAQ), a simplified nutritional assessment, could be comparable with serum albumin (ALB) levels as a predictor of undernutrition in cancer patients receiving outpatient chemotherapy.

METHODS

Of 111 patients, 79 patients with baseline ALB levels ≥3.5 g/dL were included in the analysis. Patients completed the revised SNAQ, which evaluated items including appetite loss, weight loss, nutritional supplement usage, age, and body mass index, using a maximum of 12 points (a score of ≥3 was marked as severe undernutrition). ALB levels were then monitored for 1 year using patient medical records.

RESULTS

There was a significant difference in event-free survival (EFS) when the SNAQ scores were classified into two groups [i.e., scores of ≤3 (SNAQ3) or scores of ≥4 (SNAQ4)]. The 150-day EFS rate was 86.8% and 57.6% for SNAQ3 and SNAQ4, respectively (hazard ratio: 2.92; 95% confidence interval: 1.31-6.51; p = 0.009). Based on the Cox proportional-hazards analysis, a higher risk of undernutrition was associated with SNAQ4 (compared with SNAQ3), C-reactive protein levels, and serum transthyretin levels.

CONCLUSION

The revised SNAQ is a predictor of undernutrition in cancer patients receiving outpatient chemotherapy. In particular, it is important that patients with a SNAQ score of ≥4 receive dietary guidance at an early stage as they are likely to become undernourished within a year.

A multicenter propensity score matched analysis in 73,843 patients of an association of nutritional risk with mortality, length of stay and readmission rates

BACKGROUND

The reported prevalences and effects of nutritional risk vary widely in the literature because of both methodological differences (e.g., screening tools and statistical analyses) and different patient populations.

OBJECTIVE

In this study the authors analyzed in-hospital mortality, 30-d mortality, readmission within 4 mo, and justified length of stay (jLoS) (determined by governmental assessment to justify financial compensation) in hospitalized patients nutritionally at risk compared with hospitalized patients not at risk.

DESIGN

This was a multicenter retrospective cohort study in 6 Belgian hospitals among inpatients in 2018. Propensity score matching was applied, including comorbidity score and exact matching for hospital, age group, sex, type of admission, living situation, and medical specialty.

RESULTS

In total, 73,843 of 85,677 patients were screened at admission, with 16,141 found to have nutritional risk (prevalence of 21.9%). Oncology patients had the highest risk prevalence of 38.3%, whereas patients receiving plastic or reconstructive surgery had a prevalence of 5.2%. Patients nutritionally at risk had higher odds of dying in the hospital (5.1% compared with 3.3%; OR: 1.56; 95% CI: 1.37, 1.76), dying within 30 d of admission (6.8% compared with 4.3%; OR: 1.62; 95% CI: 1.45, 1.81) and being readmitted within 4 mo after discharge (35.5% compared with 32.9%; OR: 1.12; 95% CI: 1.07, 1.18). These differences were consistent across hospitals. The association between being nutritionally at risk and jLoS was ambiguous.

CONCLUSIONS

One out of 5 patients included in this study was nutritionally at risk. Using propensity score matching, higher odds of in-hospital mortality, readmission, and 30-d mortality were observed. In contrast to oft-reported increased length of stay with poor nutrition, propensity matched data for jLoS suggested that this association was less pronounced in this cohort.

CT-Determined Sarcopenia in GLIM-Defined Malnutrition and Prediction of 6-Month Mortality in Cancer Inpatients

Our objective was to evaluate the clinical application of third lumbar vertebra (L3)-computer tomography (CT)-determined sarcopenia as a marker of muscle mass in cancer inpatients diagnosed with malnutrition according to the Global Leadership Initiative on Malnutrition (GLIM) criteria and to establish its association with 6-month mortality. Methods: This was an observational, prospective study in patients from an inpatient oncology unit. We performed a nutritional assessment according to GLIM criteria, including muscle cross-sectional area at L3 by CT and skeletal muscle index (SMI). Six-month mortality was evaluated. Results: A total of 208 patients were included. The skeletal muscle cross-sectional area at L3 was 136.2 ± 32.5 cm² in men and 98.1 ± 21.2 cm² in women. The SMI was 47.4 ± 12.3 cm²/m² in men and 38.7 ± 8.3 cm²/m² in women. Sarcopenia (low SMI) was detected in 59.6% of the subjects. Using SMI as a marker of low muscle mass in application of GLIM criteria, we found 183 (87.9%) malnourished patients. There were 104 deaths (50%) at 6 months. The deceased patients had a lower skeletal muscle cross-sectional area (112.9 ± 27.9 vs. 126.1 ± 37.8 cm²; p = 0.003) and a lower SMI (41.3 ± 9.5 vs. 45.7 ± 12.9 cm²/m²; p = 0.006). An increased risk of 6-month mortality was found in malnourished patients according to GLIM criteria using SMI (HR 2.47; 95% confidence interval 1.07–5.68; p = 0.033). Conclusions: Low muscle mass, assessed by L3-CT, was observed to affect more than half of cancer inpatients. The deceased patients at 6 months had a lower skeletal muscle cross-sectional area and SMI. Malnutrition according to GLIM criteria using CT-determined sarcopenia was shown to adequately predict 6-month mortality.

SeDREno study - prevalence of hospital malnutrition according to GLIM criteria, ten years after the PREDyCES study

BACKGROUND & AIMS

the last large multicenter study on disease-related malnutrition (DRM) in Spain (the PREDyCES study) showed a 23.7 % prevalence of malnutrition, according to the Nutritional Risk Screening (NRS-2002) tool. The main objective of the SeDREno study was to assess the prevalence of hospital malnutrition upon admission, according to GLIM criteria, ten years later.

METHODS

a cross-sectional, observational, multicenter study in standard clinical practice, conducted in 17 hospitals during a period of five to seven days. Patients were initially screened using the Malnutrition Universal Screening Tool (MUST), and then assessed using the GLIM criteria for diagnosis and severity grading.

RESULTS

a total of 2,185 patients, 54.8 % males, mean age 67.1 (17.0) years (50.2 % aged ≥ 70 years), were evaluated. Malnutrition was observed in 29.7 % of patients according to GLIM criteria (12.5 % severe, 17.2 % moderate). In patients ≥ 70 years malnutrition was observed in 34.8 %. The clinical conditions significantly associated with a higher prevalence of malnutrition were dysphagia (47.6 %), cognitive impairment (43.4 %), cancer (39.1 %), gastrointestinal disease (37.7 %), diabetes (34.8 %), and cardiovascular disease (33.4 %). The multivariate analysis revealed that gender, BMI, diabetes, cancer, gastrointestinal disorders, and polypharmacy were the main independent factors associated with DRM. Malnutrition was associated with an increase in length of hospital stay and death (p < 0.001).

CONCLUSIONS

DRM in admitted patients has increased in Spain in the last 10 years paralleling ageing of the population. In the SeDREno study almost one in three patients are malnourished. A systematic assessment of nutritional status allows early detection and implementation of nutritional interventions to achieve a better clinical outcome.

Body Composition and Selected Nutritional Indicators in Healthy Adults-A Cross-Sectional Study

Background

Body mass composition is subject to constant change and is multifactorially determined. Its analysis in different age groups allows a better understanding of the determinants of the human organism in health and disease.

Aim

The study was aimed to conduct cross-sectional assessment of body composition and selected nutritional indicators in healthy adults.

Methods

The cross-sectional study carried out from March 2016 to April 2018 was preceded by a monthly pilot study. All 1333 adults (women 795, 59.6%) aged 20–59 included in the study were from the urban and rural area of the Podkarpackie Province (Poland). These adults were classified into four 10-year age bands. To obtain reliable assessment, selected screening (anthropometry) and in-depth (bioelectrical impedance including phase angle and bioelectrical impedance vector analysis) methods were used.

Results

In women, the proportion of individuals affected by overweight and obesity increases significantly with age, with a less pronounced trend in men, as reflected in the observed differences in individual body composition components. A slight (0.45–0.60) correlation was also observed between body mass index (BMI) and percentage of fat mass (FM %) among men with an increasing strength of the association with age, decreasing in the 50–59 years group. In the female group, the correlations described are at a much higher level (0.80 or higher). The described changes in body composition were reflected in body type from athletic to obese, measured by means of the bioelectrical impedance vector analysis (BIVA) method.

Conclusions

Age and gender significantly differentiate body composition of the adult human body. The body composition analysis should be considered as complement screening assessment method, especially as a support for the assessment of nutritional status expressed by BMI.

Patient-Generated Subjective Global Assessment Short Form better predicts length of stay than Short Nutritional Assessment Questionnaire

OBJECTIVE

Malnutrition screening instruments used in hospitals mainly include criteria to identify characteristics of malnutrition. However, to tackle malnutrition in an early stage, identifying risk factors for malnutrition in addition to characteristics may be valuable. The aim of this study was to determine the predictive validity of the Patient-Generated Subjective Global Assessment (PG-SGA SF), which addresses malnutrition characteristics and risk factors, and the Short Nutritional Assessment Questionnaire (SNAQ), which addresses mainly malnutrition characteristics, for length of stay (LOS) in a mixed hospital population.

METHODS

Patients (N = 443) were screened with the PG-SGA SF and SNAQ in the first 72 h after admission to the lung, cardiology, or surgery ward. The McNemar-Bowker test was used to investigate the symmetry between the SNAQ and PG-SGA SF categorization for low, medium, and high risk. The predictive value of the PG-SGA SF and SNAQ was assessed by γ-regression before and after adjusting for several confounders.

RESULTS

Of the 443 patients included, 23% and 58% were categorized as being at medium/high risk for malnutrition according to the SNAQ and PG-SGA SF, respectively. The regression analysis indicated that LOS of high-risk patients according to PG-SGA SF was 36% longer than that of low-risk patients (P = 0.001). LOS in patients at high risk according to the SNAQ did not significantly differ from that of SNAQ low-risk patients.

CONCLUSIONS

The PG-SGA SF, as a proactive malnutrition screening instrument, predicts LOS in various hospital wards, whereas the SNAQ, as a reactive instrument, does not. Therefore, we recommend the PG-SGA SF for proactive screening for malnutrition risk.

A novel model with nutrition-related parameters for predicting overall survival of cancer patients

BACKGROUND

Increasing evidence indicates that nutritional status could influence the survival of cancer patients. This study aims to develop and validate a nomogram with nutrition-related parameters for predicting the overall survival of cancer patients.

PATIENTS AND METHODS

A total of 8749 patients from the multicentre cohort study in China were included as the primary cohort to develop the nomogram, and 696 of these patients were recruited as a validation cohort. Patients' nutritional status were assessed using the PG-SGA. LASSO regression models and Cox regression analysis were used for factor selection and nomogram development. The nomogram was then evaluated for its effectiveness in discrimination, calibration, and clinical usefulness by the C-index, calibration curves, and decision curve analysis. Kaplan-Meier survival curves were used to compare the survival rate.

RESULTS

Seven independent prognostic factors were identified and integrated into the nomogram. The C-index was 0.73 (95% CI, 0.72 to 0.74) and 0.77 (95% CI, 0.74 to 0.81) for the primary cohort and validation cohort, which were both higher than 0.59 (95% CI, 0.58 to 0.61) of the TNM staging system. DCA demonstrated that the nomogram was higher than the TNM staging system and the TNM staging system combined with PG-SGA. Significantly median overall survival differences were found by stratifying patients into different risk groups (score < 18.5 and ≥ 18.5) for each TNM category (all Ps < 0.001).

CONCLUSION

Our study screened out seven independent prognostic factors and successfully generated an easy-to-use nomogram, and validated and shown a better predictive validity for the overall survival of cancer patients.

Process evaluation of the implementation of a decision support system to prevent and treat disease-related malnutrition in a hospital setting

Background

Malnutrition is present in 30% of hospitalized patients and has adverse outcomes for the patient and the healthcare system. The current practice for nutritional care is associated with many barriers. The MyFood decision support system was developed to prevent and treat malnutrition.

Methods

This paper reports on a process evaluation that was completed within an effectiveness trial. MyFood is a digital tool with an interface consisting of an app and a website. MyFood includes functions to record and evaluate dietary intake. It also provides reports to nurses, including tailored recommendations for nutritional treatment. We used an effectiveness-implementation hybrid design in a randomized controlled trial. The RE-AIM (Reach, Efficiency, Adoption, Implementation, Maintenance) framework was used to perform a process evaluation alongside the randomized controlled trial, using a combination of quantitative and qualitative methods. An implementation plan, including implementation strategies, was developed to plan and guide the study.

Results

Reach: In total, 88% of eligible patients consented to participate (n = 100). Adoption: Approximately 75% of the nurses signed up to use MyFood and 50% used the reports. Implementation: MyFood empowered the patients in their nutritional situation and acted as a motivation to eat to reach their nutritional target. The compliance of using MyFood was higher among the patients than the nurses. A barrier for use of MyFood among the nurses was different digital systems which were not integrated and the log-in procedure to the MyFood website. Despite limited use by some nurses, the majority of the nurses claimed that MyFood was useful, better than the current practice, and should be implemented in the healthcare system.

Conclusions

This study used a process evaluation to interpret the results of a randomized controlled trial more in-depth. The patients were highly compliant, however, the compliance was lower among the nurses. MyFood empowered the patients in their nutritional situation, the usability was considered as high, and the experiences and attitudes towards MyFood were primarily positive. Focus on strategies to improve the nurses’ compliance may in the future improve the MyFood system’s potential.

Trial registration

The trial was registered in ClinicalTrials.gov 26/01/2018 (NCT03412695).

Female cancer survivors are more likely to be at high risk of malnutrition and meet the threshold for clinical importance for a number of quality of life subscales

BACKGROUND

The present study aimed to explore malnutrition risk, handgrip strength and quality of life (QOL) in cancer survivors.

METHODS

In total, 232 individuals completed a demographic questionnaire, Patient-Generated Subjective Global Assessment Short Form and the European Organization for Research and Treatment of Cancer QOL Questionnaire (EORTC QLQ-C30). Handgrip strength was determined using a spring-loaded handgrip dynamometer and anthropometric measurements were taken by an oncology nurse. Frequencies and distribution data, analysis of variance and chi-squared tests were then conducted.

RESULTS

The majority of the cohort were female (n = 141; 60.8%) had breast cancer (n = 62; 26.7%) and the mean ± SD body mass index (BMI) was 26.6 ± 6.2 kg m^-2 . Less than a one-third reported seeing a dietitian (n = 68; 29.3%). Over one-third reported recent weight loss (n = 88; 37.3%). Some 40.9% (n = 95) were at moderate to high risk of malnutrition, with women more likely than men to be classified as high risk (p < 0.05). Mean ± SD handgrip strength was 25 ± 15 kg and this differed significantly by gender (p = 0.00), cancer type (p = 0.01) and BMI classification (p = 0.01). One-fifth of individuals were classified as having dynapenia (n = 48; 21.1%). Median (interquartile range) QOL score was 66.7 (33.3). The proportion of individuals meeting the threshold for clinical importance for QOL subscales ranged from 12.5% (constipation) to 42.7% (physical functioning). Females were more likely than males to meet the threshold for physical functioning (p = 0.00), fatigue (p = 0.02) and pain (p = 0.01).

CONCLUSIONS

Females are more likely than males to be at high risk of malnutrition and meet the threshold for clinical significance for several QOL subscales.

Malnutrition screening on hospital admission: impact of overweight and obesity on comparative performance of MUST and PG-SGA SF

BACKGROUND/OBJECTIVES

Traditional malnutrition screening instruments, including the Malnutrition Universal Screening Tool (MUST), strongly rely on low body mass index (BMI) and weight loss. In overweight/obese patients, this may result in underdetection of malnutrition risk. Alternative instruments, like the Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF), include characteristics and risk factors irrespective of BMI. Therefore, we aimed to compare performance of MUST and PG-SGA SF in malnutrition risk evaluation in overweight/obese hospitalized patients.

SUBJECTS/METHODS

We assessed malnutrition risk using MUST (≥1 = increased risk) and PG-SGA SF (≥4 = increased risk) in adult patients at hospital admission in a university hospital. We compared results for patients with BMI < 25 kg/m² vs. BMI ≥ 25 kg/m².

RESULTS

Of 430 patients analyzed (58 ± 16 years, 53% male, BMI 26.9 ± 5.5 kg/m²), 35% were overweight and 25% obese. Malnutrition risk was present in 16% according to MUST and 42% according to PG-SGA SF. In patients with BMI < 25 kg/m², MUST identified 31% as at risk vs. 52% by PG-SGA SF. In patients with BMI ≥ 25 kg/m², MUST identified 5% as at risk vs. 36% by PG-SGA SF. Agreement between MUST and PG-SGA SF was low (к = 0.143). Of the overweight/obese patients at risk according to PG-SGA SF, 83/92 (90%) were categorized as low risk by MUST.

CONCLUSIONS

More than one-third of overweight/obese patients is at risk for malnutrition at hospital admission according to PG-SGA SF. Most of them are not identified by MUST. Awareness of BMI-dependency of malnutrition screening instruments and potential underestimation of malnutrition risk in overweight/obese patients by using these instruments is warranted.

Clinicopathological factors affecting the effect of neoadjuvant chemotherapy in patients with gastric cancer

BACKGROUND

Neoadjuvant chemotherapy is an important part of the comprehensive treatment of advanced gastric cancer (GC). The effect of neoadjuvant chemotherapy plays a key role in the prognosis of GC patients. Pathological response can represent the effect of neoadjuvant chemotherapy. However, evidence focused on pathological response and associated clinicopathological factors in GC patients is quite little. In this retrospective study, the clinicopathological factors affecting the effect of neoadjuvant chemotherapy in GC patients were investigated, and suggestions were proposed to improve the effect of neoadjuvant chemotherapy on GC.

METHODS

Retrospective analysis was performed on GC patients who received radical surgery after neoadjuvant chemotherapy from February 2016 to December 2019 at Peking Union Medical College Hospital. Relevant clinicopathological data was collected to analyze the factors influencing the effect of neoadjuvant chemotherapy. Chi-square test was used for univariate analysis. Logistic regression was used for multivariate analysis. Receiver operating characteristic curve (ROC) was used to determine the cutoff value of variables which significantly influenced the effect of neoadjuvant chemotherapy.

RESULTS

A total of 203 GC patients were included in the study. Analyses showed that patients < 60 years old (OR = 1.840 [1.016-3.332], P = 0.044), histological type of poor differentiation or signet-ring cell carcinoma (OR = 2.606 [1.321-5.140], P = 0.006), and weight loss during neoadjuvant chemotherapy (OR = 2.110 [1.161-3.834], P = 0.014) were independent risk factors for neoadjuvant chemotherapy effect. In ROC analysis of weight change and neoadjuvant chemotherapy effect, area under the curve (AUC) was 0.593 (P = 0.024) and cutoff value of weight change was - 2.95%. Chi-square test showed that patients without weight loss during neoadjuvant chemotherapy had a higher rate of oral nutritional supplement (ONS) than patients with weight loss (P = 0.039).

CONCLUSIONS

Patients <60 years old, histological type of poor differentiation or signet-ring cell carcinoma, and weight loss during neoadjuvant chemotherapy were independent risk factors for neoadjuvant chemotherapy effect in GC patients. Patients with weight loss > 2.95% during neoadjuvant may have a worse chemotherapy effect. Timely nutritional support such as ONS to maintain patients' body weight is crucial for improving the effect of neoadjuvant chemotherapy.

Effects of nursing nutrition interventions on outcomes in malnourished hospital inpatients and nursing home residents: A systematic review

CONTEXT

Malnutrition in institutionalized patients is associated with adverse outcomes and increased costs. Nurses have a crucial role in the recognition and treatment of malnutrition and empowering patients in nutritional care.

OBJECTIVE

This systematic review provides an overview of the effectiveness of nursing nutritional interventions to counteract malnutrition.

DATA SOURCES

Data were obtained through a systematic search in MEDLINE/PubMed, Cochrane, CINAHL, EMBASE and ISI Web of Science databases from inception to February 15^th 2018.

DATA EXTRACTION

Studies were eligible for inclusion when published in English, Spanish or German. Primary outcome parameters were nutritional status and dietary intake.

DATA ANALYSIS

The Evidence analysis checklist from the American Dietetic Association and GRADE were used to evaluate the methodological quality of the studies.

RESULTS

Out of 8162 studies, fifteen studies were included in the study, representing nine hospitals and six long-term care facilities. Two main categories of nursing nutrition interventions were identified; the implementation of 1) a nursing nutrition plan focusing on nursing actions in nutritional care or 2) nursing assistance in feeding support, mostly during mealtimes. Studies were heterogeneous and of most of them of low quality. This hampered drawing conclusions on effectiveness of nursing nutrition interventions on malnutrition related outcomes in clinical care. Nevertheless, six out of 15 studies reported a slightly improved nutritional status and/or clinical outcomes as a result of the interventions.

CONCLUSION

This review identified two categories of nursing nutrition interventions to counteract malnutrition. Their effectiveness needs to be further evaluated in future studies.

Association of malnutrition with all-cause mortality in the elderly population: A 6-year cohort study

BACKGROUND AND AIMS

Few studies have explored the association between malnutrition, defined by the Geriatric Nutritional Risk Index (GNRI), and all-cause mortality, particularly in the Chinese population. This study aimed to investigate the association between the GNRI and all-cause mortality in the elderly population.

METHODS AND RESULTS

Participants aged ≥60 years were eligible for this study and were divided into three groups by the GNRI: An adequate nutrition group, participants with a GNRI ≥98; mild malnutrition group, participants with a GNRI ≥82 but <98; and a severe malnutrition group, participants with a GNRI <82. The results implied that there was a positive association between severe malnutrition and all-cause mortality in the total population (hazard ratio (HR): 2.591 and 95% confidence interval (CI): 1.729-3.884), male subjects (HR: 2.903 and 95% CI: 1.718-4.906), and female subjects (HR: 2.081 and 95% CI: 1.071-4.046). Similar associations between severe malnutrition and all-cause mortality were observed in both the 60-69 and 70-79 years age groups (HR: 2.863 and 2.600, 95% CI: 1.444-5.678 and 1.394-4.849, respectively). However, no significant association was observed between mild malnutrition and all-cause mortality.

CONCLUSIONS

Severe malnutrition could increase all-cause mortality in the 60- to 79-year-old population. However, there was no association of mild malnutrition with all-cause mortality.

Impact of musculoskeletal degradation on cancer outcomes and strategies for management in clinical practice

The prevalence of malnutrition in patients with cancer is one of the highest of all patient groups. Weight loss (WL) is a frequent manifestation of malnutrition in cancer and several large-scale studies have reported that involuntary WL affects 50-80% of patients with cancer, with the degree of WL dependent on tumour site, type and stage of disease. The study of body composition in oncology using computed tomography has unearthed the importance of both low muscle mass (sarcopenia) and low muscle attenuation as important prognostic indications of unfavourable outcomes including poorer tolerance to chemotherapy; significant deterioration in performance status and quality of life (QoL), poorer post-operative outcomes and shortened survival. While often hidden by excess fat and high BMI, muscle abnormalities are highly prevalent in patients with cancer (ranging from 10 to 90%). Early screening to identify individuals with sarcopenia and decreased muscle quality would allow for earlier multimodal interventions to attenuate adverse body compositional changes. Multimodal therapies (combining nutritional counselling, exercise and anti-inflammatory drugs) are currently the focus of randomised trials to examine if this approach can provide a sufficient stimulus to prevent or slow the cascade of tissue wasting and if this then impacts on outcomes in a positive manner. This review will focus on the aetiology of musculoskeletal degradation in cancer; the impact of sarcopenia on chemotherapy tolerance, post-operative complications, QoL and survival; and outline current strategies for attenuation of muscle loss in clinical practice.
