Nutritional risk screening in noninvasively mechanically ventilated critically ill adult patients: A feasibility trial.

BACKGROUND: Malnutrition rates for critically ill patients being admitted to the intensive care unit (ICU) are reported to range from 38% to 78%. Malnutrition in the ICU is associated with increased mortality, morbidity, length of hospital admission, and ICU readmission rates. The high volume of ICU admissions means that efficient screening processes to identify patients at nutritional or malnutrition risk are imperative to appropriately prioritise nutrition intervention. As the proportion of noninvasively mechanically ventilated patients in the ICU increases, the feasibility of using nutrition risk screening tools in this population needs to be established. OBJECTIVES: The aim of this study was to compare the feasibility of using the Malnutrition Universal Screening Tool (MUST) with the modified NUtriTion Risk In the Critically ill (mNUTRIC) score for identifying patients at nutritional or malnutrition risk in this population. METHODS: A single-centre, prospective, descriptive, feasibility study was conducted. The MUST and mNUTRIC tool were completed within 24 h of ICU admission in a convenience sample of noninvasively mechanically ventilated adult patients (≥18 years) by a trained allied health assistant. The number (n) of eligible patients screened, time to complete screening (minutes), and barriers to completion were documented. Data are presented as mean (standard deviation), and the independent samples t-test was used for comparisons between tools. RESULTS: Twenty patients were included (60% men; aged 65.3 [13.9] years). Screening using the MUST took a significantly shorter time to complete than screening using the mNUTRIC tool (8.1 [2.8] vs 22.1 [5.6] minutes; p = 0.001). Barriers to completion included obtaining accurate weight history for the MUST and time taken for collection of information and overall training requirements to perform mNUTRIC. CONCLUSIONS: The MUST took less time and had fewer barriers to completion than mNUTRIC. The MUST may be the more feasible nutrition risk screening tool for use in noninvasively mechanically ventilated critically ill adults.

MUST-Plus: A Machine Learning Classifier That Improves Malnutrition Screening in Acute Care Facilities.

OBJECTIVE: Malnutrition among hospital patients, a frequent, yet under-diagnosed problem is associated with adverse impact on patient outcome and health care costs. Development of highly accurate malnutrition screening tools is, therefore, essential for its timely detection, for providing nutritional care, and for addressing the concerns related to the suboptimal predictive value of the conventional screening tools, such as the Malnutrition Universal Screening Tool (MUST). We aimed to develop a machine learning (ML) based classifier (MUST-Plus) for more accurate prediction of malnutrition. METHOD: A retrospective cohort with inpatient data consisting of anthropometric, lab biochemistry, clinical data, and demographics from adult (≥ 18 years) admissions at a large tertiary health care system between January 2017 and July 2018 was used. The registered dietitian (RD) nutritional assessments were used as the gold standard outcome label. The cohort was randomly split (70:30) into training and test sets. A random forest model was trained using 10-fold cross-validation on training set, and its predictive performance on test set was compared to MUST. RESULTS: In all, 13.3% of admissions were associated with malnutrition in the test cohort. MUST-Plus provided 73.07% (95% confidence interval [CI]: 69.61%-76.33%) sensitivity, 76.89% (95% CI: 75.64%-78.11%) specificity, and 83.5% (95% CI: 82.0%-85.0%) area under the receiver operating curve (AUC). Compared to classic MUST, MUST-Plus demonstrated 30% higher sensitivity, 6% higher specificity, and 17% increased AUC. CONCLUSIONS: ML-based MUST-Plus provided superior performance in identifying malnutrition compared to the classic MUST. The tool can be used for improving the operational efficiency of RDs by timely referrals of high-risk patients.

'Self-screening' for malnutrition with an electronic version of the Malnutrition Universal Screening Tool ('MUST') in hospital outpatients: concurrent validity, preference and ease of use.

Self-screening using an electronic version of the Malnutrition Universal Screening Tool ('MUST') has been developed but its implementation requires investigation. A total of 100 outpatients (mean age 50 (sd 16) years; 57 % male) self-screened with an electronic version of 'MUST' and were then screened by a healthcare professional (HCP) to assess concurrent validity. Ease of use, time to self-screen and prevalence of malnutrition were also assessed. A further twenty outpatients (mean age 54 (sd 15) years; 55 % male) examined preference between self- screening with paper and electronic versions of 'MUST'. For the three-category classification of 'MUST' (low, medium and high risk), agreement between electronic self-screening and HCP screening was 94 % (κ=0·74, se 0·092; P<0·001). For the two-category classification (low risk; medium+high risk) agreement was 96 % (κ=0·82, se 0·085; P<0·001), comparable with the previously reported paper-based self-screening. In all, 15 % of patients categorised themselves 'at risk' of malnutrition (5 % medium, 10 % high). Electronic self-screening took 3 min (sd 1·2 min), 40 % faster than previously reported for the paper-based version. Patients found the tool easy or very easy to understand (99 %) and complete (98 %). Patients that assessed both tools found the electronic tool easier to complete (65 %) and preferred it (55 %) to the paper version. Electronic self-screening using 'MUST' in a heterogeneous group of hospital outpatients is acceptable, user-friendly and has 'substantial to almost-perfect' agreement with HCP screening. The electronic format appears to be as agreeable and often the preferred format when compared with the validated paper-based 'MUST' self-screening tool.

An evaluation of the feasibility and validity of a patient-administered malnutrition universal screening tool ('MUST') compared to healthcare professional screening in an inflammatory bowel disease (IBD) outpatient clinic.

BACKGROUND: Malnutrition is common in inflammatory bowel disease (IBD) and is associated with poor health outcomes. Despite this, screening for malnutrition in the outpatient-setting is not routine and research in the area is limited. The present study aimed to evaluate whether agreement between malnutrition screening completed by patients and healthcare professionals (HCPs) could be achieved by comparing patient self-administered 'MUST' ('MUST'-P) with HCP administered 'MUST' ('MUST'-HCP) in a single tertiary IBD outpatient clinic. METHODS: We conducted a feasibility and validity study on adult outpatients with IBD. We collected anthropometric, nutritional and clinical data from patients. All patients completed 'MUST'-P using a self-administered questionnaire, followed by 'MUST'-HCP. 'MUST'-P was timed and feedback on ease-of-use was obtained. The risk of malnutrition was classified as low (score = 0), medium (score = 1) and high (score ≥ 2) and agreement was tested using kappa statistics (κ). RESULTS: Eighty patients were recruited (Crohn's disease: n = 49, ulcerative colitis: n = 29, unclassified: n = 2), with a mean (SD) age of 39.9 (15.1) years (51.2% were males). Seventy-one (92%) of patients found 'MUST'-P either easy or very easy. The mean (SD) time to complete 'MUST'-P was 3.1  (1.8) min (range 1-10 min). Sixty-eight (85%) of patients were at low risk of malnutrition when screened by the HCP. There was moderate agreement (κ = 0.486, P < 0.001) between 'MUST'-P and 'MUST'-HCP, with 100% agreement in scoring for medium- and high-risk categories. CONCLUSIONS: The results of the present study suggests that self-screening using 'MUST' could be effectively used in an IBD outpatient clinic to identify those at medium and high risk of malnutrition. The patient friendly version of 'MUST' ('MUST'-P) was considered quick and easy to use by patients. Implementation of self-screening with 'MUST' could improve the nutritional management of IBD patients.

Inflammation-driven malnutrition: a new screening tool predicts outcome in Crohn's disease.

Malnutrition is a frequent feature in Crohn's disease (CD), affects patient outcome and must be recognised. For chronic inflammatory diseases, recent guidelines recommend the development of combined malnutrition and inflammation risk scores. We aimed to design and evaluate a new screening tool that combines both malnutrition and inflammation parameters that might help predict clinical outcome. In a prospective cohort study, we examined fifty-five patients with CD in remission (Crohn's disease activity index (CDAI) <200) at 0 and 6 months. We assessed disease activity (CDAI, Harvey-Bradshaw index), inflammation (C-reactive protein (CRP), faecal calprotectin (FC)), malnutrition (BMI, subjective global assessment (SGA), serum albumin, handgrip strength), body composition (bioelectrical impedance analysis) and administered the newly developed 'Malnutrition Inflammation Risk Tool' (MIRT; containing BMI, unintentional weight loss over 3 months and CRP). All parameters were evaluated regarding their ability to predict disease outcome prospectively at 6 months. At baseline, more than one-third of patients showed elevated inflammatory markers despite clinical remission (36·4 % CRP ≥5 mg/l, 41·5 % FC ≥100 µg/g). Prevalence of malnutrition at baseline according to BMI, SGA and serum albumin was 2-16 %. At 6 months, MIRT significantly predicted outcome in numerous nutritional and clinical parameters (SGA, CD-related flares, hospitalisations and surgeries). In contrast, SGA, handgrip strength, BMI, albumin and body composition had no influence on the clinical course. The newly developed MIRT was found to reliably predict clinical outcome in CD patients. This screening tool might be used to facilitate clinical decision making, including treatment of both inflammation and malnutrition in order to prevent complications.

Health-related quality of life and associated factors in people with HIV: an Irish cohort study.

BACKGROUND: Considering the chronic and debilitating nature of HIV infection, health-related quality of life (HRQoL) is an important patient-reported clinical outcome to better understand the effects of this infection and its treatment on patients' lives. The purpose of this study was to assess the HRQoL and its association with sociodemographic, behavioural, clinical, nutrition-related factors and social support in an Irish HIV cohort. METHODS: A cross-sectional, prospective study using the Medical Outcomes Study HIV Health survey assessed the 10 dimensions of HRQoL and summarised as Physical Health Summary (PHS) and Mental Health Summary (MHS) scores. Participants were categorised as having good or poor PHS and MHS using the standardised mean score of 50. The variables independently associated with PHS and MHS were identified using multivariable logistic regression models. RESULTS: Overall, 521 participants completed the HRQoL questionnaire. The median (IQR) PHS and MHS scores were 56 (47-60) and 51 (41-58) respectively. All the covariate groups had lower MHS than PHS. Participants with symptoms of HIV reported the lowest median (IQR) PHS score 44.7 (32.-54.5) and MHS score 36.1 (28.6-48.4). Of the 10 dimensions of HRQoL, the lowest scores were for the energy level and general health. Symptoms of HIV, co-morbidities, social support, employment and ethnicity had independent association with both PHS and MHS. Gender, education, alcohol intake and HIV-complications were associated with PHS. Age, illicit drugs, BMI and malnutrition were associated with MHS. However, CD4 count and viral load were not independently associated with PHS and MHS in multivariable regression models. CONCLUSION: Overall, HIV-infected people in this cohort had an average level of HRQoL. However, it is impaired in people with symptoms and co-morbidities, and not independently associated with CD4 and viral load. Alleviating HIV symptoms and preventing co-morbidities are important in managing HIV. Providing psychosocial supports for behaviour modification and return to work or exploring new opportunities will help to improve HRQoL. Healthcare providers and policy makers need to plan and implement programs to routinely assess the HRQoL in a systematic method to facilitate a holistic management of HIV.

Enhancing the quality of oral nutrition support for hospitalized patients: a mixed methods knowledge translation study (The EQONS study).

AIM: The aim of this study was to report a multifaceted knowledge translation intervention to facilitate use of the Malnutrition Universal Screening Tool and innovation in nutritional care for patients at risk of malnutrition. BACKGROUND: Malnutrition among hospitalized patients is a widespread problem leading to adverse health outcomes. Despite evidence of the benefits of malnutrition screening and recommendations for achieving good nutrition, shortfalls in practice continue. DESIGN: A mixed method integrated knowledge translation study. METHODS: The knowledge translation intervention comprised nutrition champions supported by knowledge translation facilitators and an action planning process. Data collection was undertaken over 18 months between 2011-2012 in a hospital in England. Data comprised observation of mealtimes, audit of patient records, survey of nurses and semi-structured interviews with nutrition champions, knowledge translation facilitators, senior ward nurses and nurse managers. FINDINGS: Statistically significant relationships (Chi Square) were observed between self-reported confidence of nurses (a) to assess patients using the Malnutrition Universal Screening Tool, (b) to teach colleagues how to use the Malnutrition Universal Screening Tool and (c) to ensure that patients were assessed within 24 hours of admission. Ward-based nutrition champions facilitated successful innovation in nutrition support. Contextual factors operating at micro (ward), meso (organization) and macro (healthcare system) levels acted as barriers and enablers for change. CONCLUSION: Nutrition champions were successful in increasing the timely assessment of patients at risk of malnutrition and promoting innovation in nutritional care. Support from knowledge translation facilitators helped nutrition champions develop their role and work collaboratively with senior ward nurses to implement action plans for improving nutrition.

Risk of malnutrition and zinc deficiency in community-living elderly men and women: the Tromsø Study.

OBJECTIVE: Elderly people may be at particular risk of Zn deficiency due to an increased prevalence of malnutrition. The aim of the present study was to evaluate the Zn status in community-living elderly people at risk of malnutrition. DESIGN: Cross-sectional population-based survey. Individuals at risk of malnutrition were identified by the Malnutrition Universal Screening Tool. Zn status was assessed by measuring serum Zn. Logistic regression was performed to evaluate the association between the risk of malnutrition and Zn deficiency. SETTING: Municipality of Tromsø, Norway. SUBJECTS: Random sample of 743 men and 778 women aged 65-87 years. RESULTS: Zn deficiency was found in 10.1% of the participants, including 13.1% of the men and 7.3% of the women. Among the men and women at risk of malnutrition, 31.0% and 12.7%, respectively, had Zn deficiency. In a model adjusted for age, gender, serum albumin and smoking status, Zn deficiency was positively associated with the risk of malnutrition (OR=2.2; 95% CI 1.3, 3.6). CONCLUSIONS: Overall, Zn deficiency was found in one out of ten community-living elderly people and was associated with the risk of malnutrition. Our results encourage the assessment of Zn status in elderly people at risk of malnutrition, with a special emphasis on elderly men.

Nutritional screening of elderly patients: a health improvement approach to practice.

INTRODUCTION: Almost 60% of elderly care in-patients are at risk of malnutrition. Malnourished patients have poorer clinical outcomes and this is a key factor with respect to prolonging the length of stay. Since 2003, the Malnutrition Universal Screening Tool (MUST) has been advocated as a method for identifying these at-risk patients. Screening should take place on admission; however, the Trust has set a stretch target of aiming to document the score accurately within 6 h of admission. METHODS: Three 'care of the elderly' wards participated in the project. Each month, the timeliness (within 6 h of admission) and accuracy (compared to a dietician assessment) of the MUST scores on the wards were reviewed. Plan-Do-Study-Act cycles were used to rapidly test changes in the ward areas. Tests included a study day, one-to-one ward-based nutrition training, a focus on the use of alternative anthropometric measurements, the development of a training pack and the identification of the challenges for undertaking accurate and timely assessments. RESULTS: Baseline data identified that a MUST was documented in <60% of patients within 6 h of admission and that only 70% were accurate. After implementation of the change package, all the wards achieved an improvement and documented MUST within 6 h of admission; one ward achieved 90% accuracy in the scores. CONCLUSIONS: Ward teams receiving training and monthly feedback of their results creates ownership, momentum and maintains enthusiasm for striving to reach stretch targets. The team continues to work on improving accurate nutritional screening across the Trust by using quality improvement methodologies.

The Accuracy of Height Prediction Equations in Greek Patients: A Cross-Sectional Study.

In clinical settings, standing height measurement is often difficult to perform due to patients' inability to stand upright. Height prediction equations derived from measurements of the length of other body segments have been published; however, they are not readily applicable to all populations since ethnic differences affect the relationship between standing height and body segment length. This cross-sectional study aimed to examine the accuracy of height prediction using the Malnutrition Universal Screening Tool (MUST) height predictive equations among Greek patients and to develop new, nationally representative equations. The study population consisted of 1198 Greek adult outpatients able to stand upright without assistance and without medical conditions that affected their height. Standing height, ulna length, knee height and demi-span measurements were obtained from 599 males and 599 females. Patients were stratified into age groups of <55 and ≥55 years, <60 and ≥60 years and <65 and ≥65 years according to the categories indicated by the MUST for height prediction from alternative measurements. There were positive correlations between standing height and ulna length and knee height and demi-span length (p < 0.001) in both sexes and all age categories. A strong correlation was observed between the measured and predicted standing height using ulna length (rho = 0.870, p < 0.001), knee height (rho = 0.923, p < 0.001) and demi-span length (rho = 0.906, p < 0.001). The average difference between the MUST indicative equations' height predictions from alternative measurements and actual height was -3.04 (-3.32, -2.76), -1.21 (-1.43, -0.988) and 2.16 (1.92, 2.41), respectively. New height prediction equations for Greek patients were identified, with the predicted values closer to the measured standing heights than those predicted with the MUST indicative equations for height prediction from alternative measurements.

The role of malnutrition universal screening tool in predicting outcomes after radical cystectomy.

PURPOSE: The Malnutrition Universal Screening Tool integrates body mass index, unintentional weight loss and present illness to assess risk for malnutrition. The predictive role of 'MUST' among patients undergoing radical cystectomy is unknown. We investigated the role of 'MUST' in predicting postoperative outcomes and prognosis among patients after RC. MATERIALS AND METHODS: We conducted a multicenter retrospective analysis of 291 patients who underwent radical cystectomy in 6 medical centers between 2015 and 2019. Patients were stratified to risk groups according to the 'MUST' score [low risk (n = 242) vs. medium-to-high risk (n = 49)]. Baseline characteristics were compared between groups. Endpoints were 30-day postoperative complications rate, cancer-specific-survival and overall survival. Kaplan-Meier curves and Cox-regression analyses were used to evaluate survival and identify predictors of outcomes. RESULTS: Median age of the study cohort was 69 years (IQR 63-74). Median duration of follow up for survivors was 33 months (IQR 20-43). Thirty-day major postoperative complications rate was 17%. Baseline characteristics were not different between the 'MUST' groups, and there was no difference in early post-operative complication rates. CSS and OS were significantly lower (p ≤ 0.02) in the medium-to-high-risk group ('MUST' score≥1) with estimated 3-year CSS and OS rates of 60% and 50% compared to 76% and 71% in the low-risk group, respectively. On multivariable analysis, 'MUST'≥1 was an independent predictor of overall- (HR = 1.95, p = 0.006) and cancer-specific-mortality (HR = 1.74, p = 0.05). CONCLUSIONS: High 'MUST' scores are associated with decreased survival in patients after radical cystectomy. Thus, the 'MUST' score may serve as a preoperative tool for patient selection and nutritional intervention.

Outpatient screening with the Royal Free Hospital-Nutrition Prioritizing Tool for patients with cirrhosis at risk of malnutrition.

OBJECTIVES: Malnutrition is common among inpatients with cirrhosis. However, data on the prevalence of malnutrition among stable ambulatory patients with cirrhosis is lacking. We sought to investigate the prevalence of patents at risk of malnutrition (ARMN) among ambulatory patients with cirrhosis using the Royal Free Hospital-Nutrition Prioritizing Tool (RFH-NPT) and the Malnutrition Universal Screening Tool (MUST) and compare their correlation to clinical outcomes. METHODS: Patients attending an outpatient liver cirrhosis clinic at a tertiary hospital were screened for ARMN using both the RFH-NPT and MUST (defined by a score of ≥2 for either tool). Differences in clinical outcomes after 6 mo were compared. RESULTS: There were 134 patients recruited. The RFH-NPT identified more ARMN patients compared with MUST (32.8% versus 8.2%; P < 0.01; Cohen κ, 0.27 [95% CI, 0.12-0.42]; P < 0.001). Fluid overload at recruitment was the only independent predictor of disagreement between the RFH-NPT and MUST (odds ratio [OR], 43.14; 95% CI, 8.70-214.00; P < 0.001). There was a trend toward an increased risk of mortality for ARMN patients by the RFH-NPT (hazard ratio, 3.58; 95% CI, 0.81-15.83; P = 0.06) but not by the MUST (P = 0.62). The incidence of hospital admissions in ARMN patients was higher by the RFH-NPT, with an incidence rate ratio of 13.27 (95% CI, 5.11-43.70; P < 0.001), but not in ARMN patients by the MUST (P = 0.85). Being ARMN by the RFH-NPT was the only independent predictor of hospital admissions (OR, 15.08; 95% CI, 2.47-91.98; P = 0.003). CONCLUSIONS: The RFH-NPT identified more ARMN patients when compared with the MUST, especially among patients with fluid overload. Patients at risk of malnutrition were at an increased risk of hospital admissions and possibly death.

The association between GLIM criteria-defined malnutrition and 2-year unplanned hospital admission in outpatients with unintentional weight loss: A retrospective cohort study.

BACKGROUND: This study aimed to assess malnutrition using the Global Leadership Initiative on Malnutrition (GLIM) criteria and Subjective Global Assessment (SGA) at baseline and determine the GLIM criteria that best predicted unplanned hospitalization in outpatients with unintentional weight loss (UWL). METHODS: We performed a retrospective cohort study of 257 adult outpatients with UWL. The GLIM criteria and SGA agreement were reported using the Cohen kappa coefficient. Kaplan-Meier survival curves and adjusted Cox regression analyses were used for survival data. Logistic regression was used for the other correlation analysis. RESULTS: This study collected data from 257 patients for 2 years. Based on the GLIM criteria and SGA, malnutrition prevalence was 79.0% and 72.0%, respectively (κ = 0.728, P < 0.001). Using the SGA as a standard, GLIM had a sensitivity of 97.8%, a specificity of 69.4%, a positive predictive value of 89.2%, and a negative predictive value of 92.6%. Malnutrition was associated with higher rates of unplanned hospital admission independent of other prognostic factors (GLIM: hazard ratio [HR]=2.85, 95% CI=1.22-6.68; SGA: HR=2.07, 95% CI=1.13-3.79). Of the five GLIM criteria-related diagnostic combinations, disease burden or inflammation was the most important to predict unplanned hospital admission in multivariable analysis (HR=3.27, 95% CI=2.03-5.28). CONCLUSION: There was good agreement between the GLIM criteria and the SGA. GLIM-defined malnutrition, as well as all five GLIM criteria-related diagnosis combinations, had the potential to predict unplanned hospital admissions in outpatients with UWL within 2 years.

Sarcopenia-related gut microbial changes are associated with the risk of complications in people with cirrhosis.

Background & Aims: Sarcopenia and gut dysbiosis are common in individuals with cirrhosis. However, the association between sarcopenia and microbial alterations, and the subsequent impact on cirrhotic outcomes are poorly understood. This study aimed to identify muscle-dependent microbial changes and related risks of cirrhotic complications. Methods: From September 2018 to December 2020, 89 individuals with cirrhosis and 16 healthy volunteers were prospectively enrolled. Muscle and nutritional status, serum amino acids, and fecal microbiota were analyzed. The association between microbial signatures of sarcopenia and cirrhotic complications was investigated. Results: A decline in muscle mass and strength were associated with gut microbial alterations in individuals with cirrhosis. The greatest microbial dissimilarity was observed between those with sarcopenia (both decline in muscle mass and strength) and those with normal-muscle status (p = 0.035). Individuals with sarcopenia had lower serum levels of alanine, valine, leucine, isoleucine, proline, tryptophan and ornithine. Besides, gut microbial functions associated with amino acid biosynthesis were significantly reduced in individuals with sarcopenia and cirrhosis. Depletion of Dialister, Ruminococcus 2, and Anaerostipes were associated with cirrhotic sarcopenia, and significantly correlated with the serum levels of amino acids. Individuals with coexistent depletion of Ruminococcus 2 and Anaerostipes developed more infectious (44.4% vs. 3.0%) and non-infectious (74.1% vs. 3.0%) complications, and more hospitalizations (54 vs. 3) than those with cirrhosis with good microbial signatures (all p <0.001). In contrast, fecal enrichment of Ruminococcus 2 and Anaerostipes independently decreased the risk of 1-year complications. Conclusions: Sarcopenia-related fecal microbial alterations are associated with cirrhotic complications. These findings may facilitate measures to improve the outcomes of individuals with cirrhosis and sarcopenia by modifying gut microbiota. Impact and implications: The composition and biosynthetic functions of gut microbiota are significantly changed in individuals with sarcopenic cirrhosis. Those with a sarcopenia-related poor microbial signature, in which Ruminococcus 2 and Anaerostipes were both depleted, had significantly more infectious and non-infectious complications, as well as more hospitalizations. These findings highlight the therapeutic potential of modifying the gut microbiota of individuals with sarcopenic cirrhosis to improve their clinical outcomes.

Nutritional Risk Screening in Hospitalized Adults Using the Malnutrition Universal Screening Tool at a Tertiary Care Hospital in South India.

Background and objectives Malnutrition is still widely prevalent in India. Various nutritional screening tools have been developed to screen for nutritional risk status but no one tool is considered the best. The Malnutrition Universal Screening Tool (MUST) is accepted by the European Society for Clinical Nutrition and Metabolism and validated for use in hospitalized adults. Hence, it was used in this study to estimate the prevalence of malnutrition in hospitalized adults and its association with socioeconomic inequality. Methods A sample of randomly selected 358 ambulatory hospitalized patients above 18 years of age was used in the study. Data pertaining to demography, socioeconomic status, medical history, and MUST were collected using a structured questionnaire. The height and weight of the patients were measured, and their BMI was determined. The patients were classified into five socioeconomic classes and their MUST scores were determined. Results Statistically significant (P < 0.05) increasing trend was observed in the height, weight, and BMI of patients with increasing socioeconomic status. Diabetes mellitus (39%) followed by hypertension (30%) were the predominant comorbid conditions. According to MUST, the overall prevalence of medium and high risk of malnutrition was 11% and 24%, respectively, and the socioeconomic class that was most impacted was Class 4 (1,130-2,259 INR per capita monthly income). Interpretation and conclusions Socioeconomic status influences the prevalence of malnutrition, comorbid conditions, and the anthropometric measurements of admitted patients. The prevalence of nutritional risk status irrespective of sex was found to be 34.91% (24.3% in males and 10.61% in women) in the study.

Association of nutrition risk screening 2002 and Malnutrition Universal Screening Tool with COVID-19 severity in hospitalized patients in Iran.

BACKGROUND: Malnutrition affects normal body function and is associated with disease severity and mortality. Due to the high prevalence of malnutrition reported in patients with coronavirus disease 2019 (COVID-19), the current study examined the association between malnutrition and disease severity in hospitalized adult patients with COVID-19 in Iran. METHODS: In this prospective observational study, 203 adult patients with COVID-19 verified by real-time polymerase chain reaction test and chest computed tomography were recruited from those admitted to a university hospital in Iran. To determine COVID-19 intensity, patients were categorized into four groups. Malnutrition assessment was based on the Malnutrition Universal Screening Tool (MUST) and nutrition risk screening score (NRS-2002). An ordinal regression model was run to assess the association between malnutrition and disease severity. RESULTS: In the studies sample of Iranian patients with COVID-19, 38.3% of patients had severe COVID-19. According to NRS-2002, 12.9% of patients were malnourished. Based on MUST, 2% of patients were at medium, and 13.4% of patients were at high risk of malnutrition. Malnutrition was associated with a higher odds of extremely severe COVID-19 according to NRS-2002 (odds ratio, 1.38; 95% confidence interval, 0.21-2.56; P=0.021). CONCLUSIONS: Malnutrition was not prevalent in the studies sample of Iranian patients with COVID-19; however, it was associated with a higher odds of extremely severe COVID-19.

GLIM criteria using NRS-2002 and MUST as the first step adequately diagnose the malnutrition in Crohn's disease inpatients: A retrospective study.

Objective: The Global Leader Initiative on Malnutrition (GLIM) criteria have been recommended for malnutrition diagnosis recently, for which the first step is malnutrition risk screening with any validated tool. This study aims to investigate the incidence of nutritional risk and malnutrition in Crohn's disease inpatients and compare the suitability of Nutritional Risk Screening 2002 (NRS-2002) and Malnutrition Universal Screening Tool (MUST) as the first-step screening tool for GLIM criteria. Methods: We retrospectively analyzed the clinical data of Crohn's disease inpatients in our hospital from August 2016 to December 2019. NRS-2002 and MUST were used for nutritional screening at the time of admission. GLIM and Patient Generated-Subjective Global Assessment (PG-SGA) were used for malnutrition assessment, respectively. Patients without nutritional risk screened by NRS-2002 but with malnutrition risk screened by MUST were especially screened out. The appendicular skeletal muscle mass index (ASMI), fat-free mass index (FFMI), body fat percent (BFP), and body cell mass (BCM) were measured by the Biospace Inbody S10 composition analyzer. Results: A total of 146 Crohn's disease patients were enrolled, of which 62.3 and 89.7% had nutritional or malnutrition risk according to NRS-2002 and MUST, respectively. The prevalence of malnutrition assessed by GLIM was 59.6% (87 cases) and 82.2% (120 cases) when NRS-2002 and MUST were used as the first step of GLIM respectively. Meanwhile, 99 patients (67.8%) had malnutrition when assessed by PG-SGA. There were 41 patients who were not at nutritional risk according to NRS-2002 but were at malnutrition risk determined by MUST. At last, 33 patients were GLIM-defined, and 16 patients were PG-SGA-defined malnutrition among the 41 patients. Conclusion: The nutritional risk or malnutrition is common in Crohn's disease inpatients. It is recommended to use a variety of nutritional assessment tools for Crohn's disease inpatients. MUST can be used as a good supplement for the patients with a score of NRS-2002 lower than 3 in order to decrease the miss rate of GLIM-defined malnutrition.

Comparison of the Suitability Between NRS2002 and MUST as the First-Step Screening Tool for GLIM Criteria in Hospitalized Patients With GIST.

Objective: The Global Leader Initiative on Malnutrition (GLIM) criteria have been recommended for malnutrition diagnosis recently, for which the first step is malnutrition risk screening with any validated tool. This study aims to investigate the incidence of malnutrition risk in gastrointestinal stromal tumor (GIST) inpatients and compare the suitability of Nutritional Risk Screening 2002 (NRS2002) and Malnutrition Universal Screening Tool (MUST) as the first-step screening tool for GLIM criteria. Methods: We retrospectively analyzed the clinical data of GIST inpatients in our hospital from January 2015 to December 2019. NRS2002 and MUST were used to screen malnutrition risk at the time of admission. The diagnostic consistency of these two tools with GLIM criteria for malnutrition was analyzed, and the predictive performance of both tools for the length of hospital stay and the occurrence of complications was also evaluated in surgical and non-surgical inpatients. Results: A total of 269 GIST inpatients were included in this study, of which 45.7 and 40.9% were at malnutrition risk determined by NRS2002 and MUST, respectively. In non-surgical inpatients, NRS2002 and MUST had similar diagnostic consistency with GLIM criteria in sensitivity (93.0 vs. 97.7%), specificity (81.1 vs. 81.1%), and Kappa value (K = 0.75 vs. 0.80), and high nutritional risk classified by NRS2002 and malnutrition identified by GLIM criteria were found to be associated with the length of hospital stay. In surgical inpatients, MUST had better diagnostic consistency with GLIM criteria in sensitivity (86.1 vs. 53.5%) and Kappa value (K = 0.61 vs. 0.30) than NRS2002, but no factors were found associated with the length of postoperative hospital stay or the occurrence of complications. Conclusion: The malnutrition risk is common in GIST inpatients. NRS2002 is more suitable than MUST for the first-step risk screening of the GLIM scheme in non-surgical inpatients, considering its better performance in screening malnutrition risk and predicting clinical outcomes. MUST was found to have good diagnostic consistency with GLIM criteria for malnutrition in both non-surgical and surgical GIST inpatients, and further studies need to be conducted to investigate its predictive performance on clinical outcomes.

Current Medical Treatment for Alcohol-Associated Liver Disease.

Alcohol-associated liver disease is one of the main causes of chronic liver disease. It comprises a clinical-histologic spectrum of presentations, from steatosis, steatohepatitis, to different degrees of fibrosis, including cirrhosis and severe necroinflammatory disease, called alcohol-associated hepatitis. In this focused update, we aim to present specific therapeutic interventions and strategies for the management of alcohol-associated liver disease. Current evidence for management in all spectra of manifestations is derived from general chronic liver disease recommendations, but with a higher emphasis on abstinence and nutritional support. Abstinence should comprise the treatment of alcohol use disorder as well as withdrawal syndrome. Nutritional assessment should also consider the presence of sarcopenia and its clinical manifestation, frailty. The degree of compensation of the disease should be evaluated, and complications, actively sought. The most severe acute form of this disease is alcohol-associated hepatitis, which has high mortality and morbidity. Current treatment is based on corticosteroids that act by reducing immune activation and blocking cytotoxicity and inflammation pathways. Other aspects of treatment include preventing and treating hepatorenal syndrome as well as preventing infections although there is no clear evidence as to the benefit of probiotics and antibiotics in prophylaxis. Novel therapies for alcohol-associated hepatitis include metadoxine, interleukin-22 analogs, and interleukin-1-beta antagonists. Finally, granulocyte colony-stimulating factor, microbiota transplantation, and gut-liver axis modulation have shown promising results. We also discuss palliative care in advanced alcohol-associated liver disease.

Factors Associated with Malnutrition and Its Impact on Postoperative Outcomes in Older Patients.

Malnutrition is associated with dismal treatment outcomes in older patients but its impact in geriatric surgery has not been studied extensively. Herein, we report the prevalence of malnutrition risk, its risk factors and its association with postoperative outcomes in older patients undergoing operations of general surgery. This is a retrospective analysis of a prospectively maintained database including patients older than 65 years who were to undergo general surgery operations between 2012 and 2017. The Malnutrition Universal Screening Tool (MUST) was used for nutritional risk. Demographics, socioeconomic data, site and magnitude of the operation, various measures of comorbidity and functional dependence as well as postoperative complications based on Clavien-Dindo classification and length of stay were recorded. There were 501 patients. A total of 28.6% of them were at intermediate malnutrition risk (MUST = 1) and 14.6% were at high malnutrition risk (MUST ≥ 2). Variables independently associated with malnutrition risk (MUST ≥ 1) were smoking (Odds Ratio, OR:1.6, p = 0.041), upper gastrointestinal (GI) tract surgery (OR:20.4, p < 0.001), hepatobiliary-pancreatic surgery (OR:3.7, p = 0.001), lower GI surgery (OR:5.2, p < 0.001) and American Society of Anesthesiologists (ASA) class III/IV (OR:2.8, p = 0.001). In the multiple regression analysis adjusted for several confounding variables, the MUST score was significantly associated with postoperative death (OR:9.1, p = 0.047 for MUST = 1 and OR:11.9, p = 0.035 for MUST score ≥ 2) and postoperative hospital stay (adjusted incidence rate ratio, 1.3, p = 0.041 for MUST = 1 and 1.7, p < 0.001 for MUST ≥ 2). Malnutrition risk was highly prevalent in this sample, particularly in patients with operations of the gastrointestinal tract, in patients with poor physical status and it was associated with postoperative mortality and length of stay.
