High Risk Of Malnutrition Research Articles

The role of nutritional risk evaluation in predicting adverse outcomes among patients with severe COVID-19 in Vietnam.

As sufficient nutrition helps alleviate catabolic stress and modulate the systemic inflammatory response of the body, it plays an indispensable role in the good prognosis of critically ill patients. Thus, this study aimed to investigate the malnutrition of patients with severe COVID-19 and its association with adverse treatment outcomes. We conducted a retrospective cross-sectional study in two provincial hospitals in Hanoi from February to April 2022. Participants were patients with severe COVID-19 admitted to the Intensive Care Unit (ICU). Malnutrition risk were evaluated by Nutritional Risk Screening-2002 (NRS), Global Leadership Initiative on Malnutrition (GLIM), Prognostic Nutritional Index (PNI), and the adverse prognosis was assessed by Acute Physiology and Chronic Health Evaluation II (APACHE II). The multivariate receiver-operating characteristic (ROC) curve was applied to estimate the predictive ability of those criteria regarding worse treatment results. The percentages of malnutrition measured by NRS, GLIM, PNI, and BMI were 62.6, 51.5, 42.9, and 16.6%, respectively. Patients with more severe malnutrition assessed by GLIM, PNI, and having above target fasting blood glucose (FBG) (≥10.0 mmol/L) were more likely to have higher APACHE scores. PNI had a better diagnostic performance than NRS and BMI (AUC = 0.84, 0.81, and 0.82, respectively). In addition, FBG revealed a good prognostic implication (AUC = 0.84). A relatively high percentage of patients experienced moderate and severe malnutrition regardless of screening tools. Individuals at higher risk of malnutrition and high FBG were predicted to have more adverse treatment outcomes. It is recommended that nutritional screening should be conducted regularly, and personalizing nutritional care strategies is necessary to meet patients' nutrient demands and prevent other nutrition-related complications.

The impact of an oral nutritional supplement on body weight gain in older adults with malnutrition: an open-label randomized controlled trial

BackgroundThe global aging population is expanding rapidly and many individuals have a particularly higher risk of malnutrition. Malnutrition can lead to impaired body function, morbidity, and mortality. Meeting nutritional requirements is a key strategy to minimize multiple debilitating adverse outcomes associated with malnutrition in the elderly.Oral nutritional supplements (ONS) have been widely used as a dietary intervention for malnutrition in older adults. These supplements provide additional nutrients and calories to support nutritional requirements and have been shown to improve nutritional status, physical function, and quality of life in malnourished older adults.MethodsThis is an open-label, randomized controlled, parallel-group study including 50 institutionalized older adults (aged > 60 years) with malnutrition or at risk of malnutrition, living in a selected elderly care institution in Colombo, Sri Lanka. The aim is to assess improvement in healthy body weight gain and body composition in older adults with malnutrition at risk of malnutrition by using an ONS. Older adults will be screened for malnutrition using the Mini Nutrition Assessment (MNA) tool and eligible participants randomized using the simple random sampling technique to intervention and control groups (1:1 allocation ratio). The intervention group will consume 200 mL of ONS before bed continuously for 12 weeks. The primary outcome is the percentage who achieved at least 5% weight gain in the intervention group compared to the control group. Nutritional status (anthropometric, biochemical, clinical, and dietary), body composition (dual-energy X-ray absorptiometry), frailty, functional capacity (hand grip strength, knee extension, and Barthel index) cognitive status (Montreal Cognitive Assessment), and physical activity will be assessed as secondary outcomes at baseline and at the end of the 12-week intervention. Some measurements (anthropometry, dietary, and functional assessments) will also be performed at the end of the 4th week. Data will be analyzed using SPSS V-23.DiscussionThis study will determine whether the use of an ONS is effective in promoting healthy weight gain in older adults with malnutrition or at risk of malnutrition. In addition, investigating the impact of an ONS on multiple outcomes via clinical, nutritional, functional, and cognitive function will provide a more comprehensive understanding of the potential benefits of these supplements.Trial registrationSri Lanka Clinical Trail Registry SLCTR/2022/021.

Food Security and Human Health

Eradication of hunger is one of the sustainable development goals listed by the United Nations. By 2050 the expected world population would be 10 billion and to provide food for all, we need to prioritize food security. A robust food security ecosystem will help to ensure that hygienic, nutritious food is available to the general population of a country. A decrease in the production of nutritious and safe food or limited purchasing power of consumers leads to food insecurity. Individuals facing financial constraints are affected the most because of food insecurity and hence are at a high risk of hunger and malnutrition. A deficiency, excess or imbalance of certain nutrients in the diet leads to malnutrition. Malnutrition is often used synonymously with undernutrition, which can be because of a deficiency of protein and/or micronutrients in the diet. Among the micronutrients, iron, zinc, and folic acid deficiency is very prevalent and the leading cause of undernutrition. Protein-energy malnutrition leads to conditions like Marasmus and Kwashiorkor. The common infectious diseases associated with undernutrition are pneumonia, diarrhoea, malaria, measles, and AIDS. Thus, food insecurity poses challenges not only to addressing public health but also affects the overall economic growth and socio-political stability of any nation. Hence at the global level, several programmes have been envisioned by the World Health Organization and United Nations Standing Committee on Nutrition. In context to the Indian population, the Government of India has started implementing various initiatives to establish food security. However, issues such as climate change, drought, floods, demographic changes, wars, increasing global population and pandemics need to be constantly addressed to achieve sustainable developmental goals. In this review, we have discussed what food security is and how in its absence, malnutrition predominates in a sizable population, especially children. The consequences of nutrient deficiency and their relationship with immunity and infection are highlighted and finally, the efforts that are being taken to tackle food security at a global level and in context to Indian issues are discussed.

34 Dysphagia at the front door: profiling dysphagia in a frail population presenting to the emergency department

Abstract Background The prevalence of both frailty and dysphagia advances with age. Worsening dysphagia increases the degree of frailty and reduces quality of life. The aim of this study was to describe the characteristics and mortality risk of a population of patients identified for Speech and language therapy (SLT) review in a Frailty at the Front Door (FFD) team. Methods A FFD team performs comprehensive geriatric assessment (CGA) for older frail patients presenting to the emergency department. To assist service planning, all patients were screened for the possible presence of dysphagia using the 4QT and those with a response to 1 or more screening questions underwent SLT review. Data were collected from consecutive SLT patient records and a hospital based patient database of CGAs over a 3-month period. Age, gender, 4AT, MST malnutrition risk screen, clinical frailty score (CFS), nursing home (NH) residence, dysphagia outcome severity scale, need for acute hospital admission and mortality rate at 1000 days was collected. Data were entered onto Excel and analysed using descriptive statistics. Results 69 swallow assessments were carried out. The mean age was 83 (+/−9) years. 71% (n = 49) were female. The 4AT was ≥4 in 36% (n = 25). 42% (n = 29) were at risk of malnutrition. The CFS was ≥6 in 62% (n = 43). 23% (n = 16) resided in a nursing home, 72% (n = 50) had dysphagia, 92% (n = 63) required hospital admission and 36% (n = 25) were experiencing their ‘last 1,000 days’ at follow-up. Conclusion Older patients presenting to the ED with a coexisting dysphagia are at high risk of malnutrition and delirium, moderately frail, present with moderate dysphagia, and are more likely to require acute hospital admission. This cohort need early screening, identification, assessment and intervention, in order to reduce dysphagia related risks and improve patient outcomes, particularly given the high proportion that are in their last 1,000 days.

Malnutrition in cancer patients: Causes, consequences and treatment options

Cancer patients are at a high risk of malnutrition and disease-associated catabolic derangements. It is important to differentiate between ‘simple’ – voluntary or involuntary - caloric restriction with protein-sparing ketogenic metabolic adaptation and cachexia, characterized by the combination of weight loss and dysmetabolism, most prominently systemic inflammation. While both conditions result in the sacrifice of fat and protein stores and thus impact on treatment tolerance, complication rates and survival, the presence of metabolic derangements is especially dangerous by straining multiple organ functions. To avoid underdiagnosing and undertreating malnutrition, all cancer patients should be routinely screened for nutritional risk. At-risk patients require comprehensive assessment for contributing and treatable causes and, if available, multi-professional efforts to improve food intake, support anabolism, alleviate distress and antagonize pro-inflammatory processes. In curative settings, anabolic support should accompany or even precede anticancer treatments. Prehabilitation before major surgery, has been studied extensively, including muscle training as well as nutritional and/or psychological support. Recent meta-analyses report a consistent benefit on functional capacity and possible improvement in postoperative complications and length of hospital stay. In palliative settings, prevailing catabolic derangements require careful assessment of the individual constellation of disturbed functions and an empathic evaluation of benefits and risks of nutritional interventions. This is of special relevance in patients with an expected survival of less than a few months. Due to the complex interactions of mechanical, metabolic and psychological factors, multi-professional teams should be involved.

311 Nutrition and dietetics on a Frailty at the Front Door Team, what does it look like?

Abstract Background A dietitian was introduced to the Frailty at the Front Door team (FFDT) in January 2022. The introduction of the Malnutrition Screening Tool (MST) to the Comprehensive Geriatric Assessment (CGA) resulted in a 47% increase in dietetic referrals. The aim of this study was to understand the characteristics of this population and how intervention was initiated. Methods Over a five month period, data was collected from the CGAs administered. Gender, Clinical Frailty Score (CFS), MST score (high risk of malnutrition is defined as MST ≥2), method of referral, patients admitted under a specialty, referrals to Community Nutrition and Dietetics Services (CNDS) and those discharged from dietetics. The data was prospectively entered into an excel spreadsheet and analysed using descriptive statistics. Results 206 frail older adults (≥ 75 yrs) were referred and seen for dietetic intervention. Male to female ratio was 1: 1.75.The mean CFS was 5.8. 89% (n = 183) had MST ≥2. 83% (n = 171) of referrals were made by FFDT, 6% (n = 12) were referred via the hospitals’ electronic referral system. 64% (n = 132) were admitted to the acute hospital while a further 20% (n = 41) were referred to CNDS. The remaining 16% were either transferred to a different hospital or discharged from the dietetics service. Of those admitted, the data was broken down into the top 5 specialities; Geriatrics: 18% (n = 37), Acute Medicine: 16.5% (n = 34), Endocrinology: 12% (n = 25), General Medicine: 10% (n = 20) and Respiratory: 8.2% (n = 17). Conclusion High risk of malnutrition is highly prevalent in frail older adults presenting to the ED and through a number of medical specialties. Increased awareness identifies these patients so that targeted interventions early can reduce adverse outcomes in hospital or the community. Screening for malnutrition with a dietitian embedded in the FFDT identifies a much bigger proportion of those who need intervention than the traditional referral method.

Nutritional Status and Risk of Sarcopenia among Hospitalized Older Adults Residing in a Rural Region in Turkey.

This study aimed to determine the prevalence of sarcopenia and its associated factors in community-dwelling older adults at risk of malnutrition based on the Mini Nutritional Assessment (MNA), Prognostic Nutritional Index (PNI), and Geriatric Nutritional Risk Index (GNRI). The study participants were 345 adults aged >65 years who visited Geriatric Internal Medicine outpatient clinics. The study included people without acute illness for whom the risk of malnutrition could be assessed and appropriate measurements taken. At the baseline visit, participants' data and measurements were gathered. The primary data included sociodemographic details, anthropometric measurements, malnutrition screening tests, and functional assessments. The participants' mean age was 76.21±5.59 years, and 57.1% were men (n=97). The prevalence rate of sarcopenia was 45.5%. Compared to individuals without sarcopenia, those with it were older; had lower MNA, PNI, and GNRI scores; and had lower muscle mass, muscle strength, and lower leg circumferences (p<0.001). After adjusting for potential confounding factors, we found that sarcopenia, advanced age, male sex, high risk of malnutrition, calf circumference, and a low PNI score were all significantly associated with a low GNRI score (p<0.001). Sarcopenia was significantly associated with advanced age, male sex, and high risk of malnutrition. Patients' nutritional and functional status should always be assessed for therapeutic interventions and lifestyle changes.

Length of Hospital Stay and Its Associated Factors among Surgical Patients in Hospital Serdang

Introduction: Hospital length of stay (LOS) is one of the measurable indicators which can be used to evaluate hospital administration, operative performance, and quality of patient care. Prolonged LOS has been associated with poor outcomes in patients and inefficient use of hospital resources. Due to the scarcity of findings in this field in Malaysia, this study aims to identify the factors affecting LOS. Methods: A single health facility-based retrospective cross-sectional study was conducted in Hospital Serdang. Data of patients admitted to the surgical ward from 2017 to 2021 were retrieved. Result: A total of 114 surgical patients’ data were analysed, of which most were adults (72.8%), female (69.3%) and Malay (67.5%). The mean LOS was 5.90 ± 4.35 days. Pearson correlation revealed age (r = 0.309, p = 0.001) and preoperative albumin (r = -0.397, p <0.001) having a significant correlation with LOS. An independent samples T-test showed that males had significantly higher mean LOS than females (t = 2.653, p = 0.009). Surprisingly, having been seen by dietitians and being supplemented by oral nutrition supplements (ONS) had longer stay compared to groups who were not seen by dietitians and given ONS respectively (t = 4.278, p<0.001), (t = 3.111, p = 0.002). Furthermore, those with a moderate and high risk of malnutrition spent approximately 3.27 days longer hospitalized than low-risk patients (t = -2.868, p = 0.007). Conclusion: Factors that influence LOS are age, gender, preoperative albumin, seen by a dietitian, risk of malnutrition and oral nutrition supplementation.

Risk of Malnutrition in Adults Who Have Undergone Sleeve Gastrectomy: A Retrospective Study.

Sleeve gastrectomy achieves long-term weight control by reducing gastric volume. However, postoperative gastrointestinal symptoms and insufficient nutritional intake are likely to occur, which are not conducive to physical health. A retrospective study aimed to investigate changes in nutritional status and associated factors in patients after sleeve gastrectomy. Data were collected from the medical records of patients who underwent sleeve gastrectomy at a teaching hospital in Taiwan. Data from 120 patients who met the eligibility criteria were included in the analysis. The results show that sleeve gastrectomy has a strong weight loss effect. Within 12 months, the average body mass index of the patients decreased by 13.47 kg/m2. The number of morbidly obese patients decreased from 62 (51.7%) to 3 (2.5%). However, surgery is also associated with gastrointestinal symptoms and the threat of malnutrition. The number of patients with moderate to severe nutritional risk increased from 4 (3.3%) before surgery to 24 (20%) at 12-month follow-up. Likewise, the number of patients with anemia increased from 11 (9.2%) to 29 (24.17%). Gender, constipation, and diarrhea affected postoperative nutritional status. These findings suggest that patients after sleeve gastrectomy are at risk of malnutrition and require regular monitoring. Special attention should be given to women and patients with constipation or diarrhea, as they are at a particularly high risk of malnutrition.

Current status of nutritional provision and effects of nutritional support on the clinical outcomes of acute kidney injury requiring continuous renal replacement therapy in the surgical intensive care unit.

Patients with acute kidney injury requiring continuous renal replacement therapy are at high risk of malnutrition. Nutritional support is an important part of treatment for patients with critical illness admitted to the intensive care unit. We aimed to investigate the status of nutritional provision and the effects of nutritional support on clinical outcomes. Our institution's medical records (from January 1, 2020, to December 31, 2021) were analyzed in this retrospective cohort study. We included 43 patients aged >18 years who received continuous renal replacement therapy for acute kidney injury in the surgical intensive care unit. The demographic characteristics were similar between the survivor and non-survivor groups. The protein supply per body weight (0.88 ± 0.37 g/kg vs. 0.47 ± 0.53 g/kg, p = 0.029) and the proportion of patients who met the target protein level (58.9 ± 24.9% vs. 30.8 ± 34.9%, p = 0.022) were significantly higher in the survivor group. Approximately 79.1% of the patients had a high malnutrition risk with a modified Nutrition Risk in the Critically Ill score of ≥5. The lengths of hospital and intensive care unit stays were longer in the high nutritional risk group compared with that in the low nutritional risk group, but the result was not significant. The nutritional amount provided in patients with critical illness is significantly lesser than the recommended amount. Ensuring proper nutritional support can improve the clinical outcomes.

Nutritional management of a malnourished cancer patient with high output ileostomy

High output stoma is a complication that may follow ileostomy formation, with an incidence of 23%. There is no general consensus on the limit of ileostomy production to be defined as high output. However, output of more than 2000 mL/day, can cause fluid and electrolyte imbalance, also malnutrition due to reduced nutrient absorption. Delay in recognition and treatment, especially in cancer patient with high risk of malnutrition, can further deteriorate patient’s nutritional status. A 43-year-old malnourished female with ascending colon cancer underwent tumor resection and ileocolostomy surgery. Starting from the third postoperative day, ileostomy effluent drastically increased to 2700 mL/day, causing severe hyponatremia, hypokalemia, and hypomagnesemia. Risk factors of high output stoma identified were routine prokinetic medication use and unresolved malignancy-related retroperitoneal abscess. Moreover, increment of food intake in the first days after surgery, specifically food high in insoluble fiber, was one of the contributing factors. High output stoma was then resolved by abscess drainage, discontinuation of prokinetic agent, and administration of antimotility agent. Hyponatremia and hypomagnesemia improved with correction, whereas hypokalemia needed longer time to resolve. Enteral nutrition was maintained and increased gradually to prevent further malnutrition. Oral hypotonic fluid intake was limited to 1000 mL/day and isotonic solution consumption was advised. High stoma production due to hypersecretory phase after ileostomy was expected, but thorough management would prevent patient’s deterioration that was caused by the fluid, electrolyte, and nutritional imbalances.

The Relation of Lifestyle with Inflammation at the Time of Diagnosis in Patients with Colorectal Cancer.

Colorectal cancer is one of the most common lifestyle-related types of cancer. The exact pathophysiologic mechanism in the relation between (visceral) adipose tissue, systemic inflammation and colorectal cancer remains unknown. This study aimed to assess the association of lifestyle with markers of systemic inflammation at the time of diagnosis in stage I-III colorectal cancer patients. Patients (n = 298) with stage I-III colorectal cancer from three Dutch hospitals were included at diagnosis. Several lifestyle-related variables (MUST nutritional status score, WCRF/AICR healthy lifestyle score, active smoking, alcohol consumption and BMI) and inflammatory markers (plasma levels of IL-6, IL-8, IL-10, TNFα and 'high sensitive' hsCRP) were measured at the time of diagnosis. Confounder-adjusted multivariable linear regression models were used to analyse how the lifestyle variables were associated with the inflammatory markers. Statistically significant associations were found between a better WCRF/AICR lifestyle score and lower levels of IL-6 and hsCRP. A medium and high risk of malnutrition according to the MUST score was associated with elevated levels of both IL-8 and hsCRP. An overall unhealthier lifestyle indicated by a lower WCRF/AICR lifestyle score and a higher risk of malnutrition according to the MUST score at the time of diagnosis was associated with elevated levels of inflammatory markers. These findings can contribute to formulating lifestyle advice to improve treatment outcomes and prognosis in patients having CRC in the future.

Bioimpedentiometry parameters used as indicators of frailty and malnutrition: association between G8 score and Phase angle (PHA) in elderly cancer patients.

Since the incidence of cancer increases with age, in older cancer patients important information may be missed without a Comprehensive Geriatric Assessment (CGA). On the other side, CGA is a time-consuming and complex instrument, sothat Geriatric 8 (G8) has been proposed as a more feasible screening tool to identify patients who could benefit from a CGAevaluation. G8 consists of 8 questions (patient age + 7 items derived from the Mini Nutritional Assessment questionnaire). A G8 score ≤ 14 is considered associated with frailty and risk of malnutrition. Another screening test is Bioelectrical Impedance Analysis (Bioimpedentiometry, BIA), which enables to evaluate the nutritional status through a specific parameter known as Phase angle (PhA). This study is aimed at assessing the ability of G8 alone or in combination with PhA to detect elderly cancer patients at higher risk for malnutrition who cannot undergo immediate anticancer treatments. A total of 289 cancer patients (168 men and 121 women) aged ≥ 70years old were enrolled and performed both G8 test, body mass index (BMI) and BIA assessments. A concurrent G8 score ≤ 14 and PhA < 5 defined subjects most exposed to the risk of malnutrition. An association between BMI and G8 (p < 0.001, OR 1.54) and a clinically significant relationship between G8 and PhA (p = 0.013) were observed. G8 can be used to identify patients at risk for malnutrition who would benefit from comprehensive CGA. The concurrent use of G8 and BIA presents a higher power in discriminating subjects at higher risk of malnutrition than a single test. This study suggests the need for routine assessment of nutritional status in cancer patients using combinations of methods, in order to implement strategies for individually-tailored care before starting any treatment.

Long-term outcomes in critically ill patients who survived COVID-19: The NUTRICOVID observational cohort study

Malnutrition and sarcopenia may last beyond hospital discharge, especially in patients admitted to intensive care units (ICU), having a negative impact on patient recovery and leading to disability, poor quality of life, and additional morbidity. No prior evidence is available for post-ICU management and follow-up of coronavirus disease 2019 (COVID-19) patients and their long-term evolution. This study reports on the one-year-long evolution of a cohort of COVID-19 survivors after ICU discharge, in terms of nutritional and functional status as well as health-related quality of life (HRQoL). A multicenter, ambispective, observational cohort study (NUTRICOVID study) was conducted in 16 public hospitals located in the Community of Madrid with COVID-19 survivors who were admitted to ICU during the first outbreak. Retrospective and prospective data were collected from hospital admission to one year after discharge. At hospital discharge and at 3, 6 and 12 months post-discharge, the following outcomes were recorded: weight, risk of malnutrition (MUST) and sarcopenia (SARC-F), medical nutrition therapy (MNT), functional status (Barthel index), and HRQoL (EQ-5D-5L). A total of 199 patients (70.4% male, mean age [SD] of 60.7 [10.1]) were included in the study. At hospital discharge, mean weight loss was 16.4% (8.0%), whereas most patients gained weight after discharge with an increase of 16.5% (14.0%) at 12 months. The proportion of patients at high risk of malnutrition decreased from 83.2% at hospital discharge to 2.1% at 12 months. The proportion at risk of sarcopenia decreased from 86.9% at hospital discharge to 13.4% at 12 months. At hospital discharge, 69 patients received MNT by means of oral nutritional supplements (ONS) while two patients required enteral nutrition (EN). At 12 months, only 12 patients continued taking ONS, with no patients taking EN. Regarding functional status, 72.9% of patients were moderately or severely dependent at hospital discharge, whereas 87.2% showed low dependency or independency after 12 months. The EQ-VAS values increased from hospital discharge (39 [21.2]) to 6 months post-discharge and remained steady up to 12 months (72.7 [19.0]). The mean health value improved from hospital discharge (0.25 [0.41]) to 6 months post-discharge (0.80 [0.24]) and was maintained thereafter. Patients' nutritional and functional impairment at hospital discharge was high, with high dependency status and low HRQoL; however, their situation improved progressively during the 12 months following hospital discharge. Nevertheless, there is a need to define early strategies to optimize the nutritional and functional recovery of COVID-19 patients.

Geriatric nutritional risk index was associated with in-hospital mortality among cardiac intensive care unit patients.

Identifying risk factors associated with cardiac intensive care unit (CICU) patients' prognosis can help clinicians intervene earlier and thus improve their prognosis. The correlation between the geriatric nutrition risk index (GNRI), which reflects nutritional status, and in-hospital mortality among CICU patients has yet to be established. The present study retrospectively enrolled 4,698 CICU patients. Based on the nutritional status, the participants were categorized into four groups. The primary endpoint was in-hospital mortality. The length of hospital stay and length of CICU stay were the secondary endpoints. To explore the correlation between nutritional status and in-hospital mortality, a logistic regression analysis was conducted. The nonlinear associations of GNRI with in-hospital mortality were evaluated using restricted cubic spline (RCS). Furthermore, subgroup analyses were conducted to evaluate the effect of the GNRI on in-hospital mortality across different subgroups, with calculation of the p for interaction. A higher risk of malnutrition was significantly linked to an increased incidence of in-hospital mortality (High risk vs. No risk: 26.2% vs. 4.6%, p < 0.001), as well as a longer length of hospital stay (High risk vs. No risk: 15.7, 9.1-25.1 vs. 8.9, 6.9-12.9, p < 0.001) and CICU stay (High risk vs. No risk: 6.4, 3.8-11.9 vs. 3.2, 2.3-5.1, p < 0.001). An elevated GNRI was significantly associated with an increased risk of in-hospital mortality even after controlling for pertinent confounding factors (High risk vs. No risk: OR, 95% CI: 2.37, 1.67-3.37, p < 0.001, p for trend <0.001). Additionally, the RCS model showed a linear relationship between GNRI and in-hospital mortality, with the risk of in-hospital mortality significantly decreasing as GNRI increased (non-linear p = 0.596). Furthermore, in the subgroups of hypertension, ventricular arrhythmias, cardiac arrest, shock, and chronic kidney disease, there was a significant interaction between nutritional status and in-hospital mortality. Among CICU patients, a low GNRI was a significant predictor of in-hospital mortality. Furthermore, patients with a higher risk of malnutrition, as indicated by low GNRI values, experienced significantly longer hospital and CICU stays.

Adequacy of Nutrient Intake and Malnutrition Risk in Older Adults: Findings from the Diet and Healthy Aging Cohort Study.

There is a lack of data on the adequacy of nutrient intake and prevalence of malnutrition risk in Asian populations. The aim was to report on the nutrient intake and prevalence of malnutrition risk in a community sample of older adults in Singapore. Analysis was performed on 738 (n = 206 male, n = 532 male, aged 67.6 ± 6.0 years) adults 60 years and above. Intakes of macro- and micronutrients were evaluated against the Recommended Dietary Allowances (RDAs). Malnutrition risk was assessed using the Nutrition Screening Initiative Determine Your Nutritional Health checklist. It was found that 90.5% older adults exceeded the sugar intake, 68.5% males and 57.1% females exceeded the intake limit for saturated fat, and 33% males had inadequate dietary fiber intake when compared to the RDAs. Inadequate dietary calcium intake was found in 49.5% males and 55.3% females. There were 22.3% of older adults at moderate to high malnutrition risk. Singaporean older adults need to reduce their dietary intakes of sugar and saturated fat and increase their intakes in dietary fiber and calcium. Current findings provide public health awareness on the importance of healthy eating and will facilitate decision making by health promotors to deliver targeted nutrition care programs.

High prevalence of malnutrition in systemic sclerosis: Results from a French monocentric cross-sectional study

ObjectivesSystemic sclerosis (SSc) can cause malnutrition due to frequent gastrointestinal involvement. However, prevalence of malnutrition in SSc is poorly known. The aim of this study was to evaluate the prevalence of malnutrition in SSc and its potential associations with disease features in patients from a tertiary referral center. MethodsAll patients meeting American College of Rheumatology/European Alliance of Associations for Rheumatology criteria for SSc followed between January 1, 1985, and January 1, 2019, at the Department of Internal Medicine, Saint Eloi University Hospital, were included. Malnutrition was assessed using the 2020 French recommendations for SSc and the malnutrition universal screening tool score. Severe malnutrition was defined via the French Haute Autorité de Santé (National Health Authority) 2007 criteria. ResultsA total of 120 patients were included, with mean age 64 (± 15) y and a female-to-male sex ratio of 5:1. According to 2020 French recommendations, 71 patients (59.2%) were malnourished and 30 (25%) had at least one criterion of severe malnutrition. With the malnutrition universal screening tool score, 41.7%, 20%, and 38.3%, respectively, had low, medium, and high risk of malnutrition. Multivariate analysis revealed the following results: 1) malnutrition was associated with cardiac involvement (P < 0.01); 2) a high malnutrition universal screening tool score was also associated with specific cardiac involvement (P < 0.01); and 3) severe malnutrition was strongly correlated with interincisal distance <35 mm (P = 0.02). ConclusionsMalnutrition affects more than half of SSc patients and is associated with specific cardiac involvement. Interincisal distance <35 mm could be a red flag for severe malnutrition in SSc.

Nutritional risk and clinical outcomes of COVID-19 in hospitalized children and adolescents: a multicenter cohort

ObjectiveTo verify the association between nutritional risk on admission and clinical outcomes of COVID-19 in hospitalized children and adolescents. MethodsMulticenter cohort study was conducted in two cities in the northeastern region of Brazil, with children under 18 years of age laboratory diagnosed with COVID-19. Sociodemographic data and nutritional risk screening by STRONGKids (low, medium and high risk) were collected remotely and in hospital records, respectively. The outcomes assessed were the need for ICU admission, length of stay (< 10 days or ≥ 10 days), critical cases, and death. Multivariable logistic regression models were used to evaluate the effects of high nutritional risk on COVID-19 clinical outcomes. Results103 individuals were evaluated, of these 35 (34.0%) had low risk, 44 (42.7%) medium risk, and 24 (23.3%) had high risk of malnutrition. In multivariate analysis, ICU bed admission (OR: 4.57; 95%CI, 1.39-4.97; p = 0.01), hospitalization longer than or equal to ten days (OR: 3.96; 95%CI, 1.22-2.83; p = 0.02) and critical cases (OR: 4.35; 95%CI, 1.08-7.55; p = 0.04) were associated with high nutritional risk. Death was not associated with high nutritional risk. ConclusionsChildren and adolescents with high nutritional risk by STRONGkids at hospital admission were more likely to be admitted to the ICU, have hospitalization longer than or equal to ten days, and have critical cases when infected with SARS-CoV-2.

TNF-α-1031T/C gene polymorphism as a predictor of malnutrition in patients with gastric cancer.

Malnutrition is a complex clinical syndrome, the exact mechanism of which is yet not fully understood. Studies have found that malnutrition is associated with anorexia and inadequate intake, tumor depletion, leptin, tumor-induced metabolic abnormalities in the body, and catabolic factors produced by the tumor in the circulation and cytokines produced by the host immune system. Among these, single nucleotide polymorphisms (SNPs) are present in the gene encoding the pro-inflammatory cytokine TNF-α. The objective of this study was to investigate TNF-α -1,031 T/C gene polymorphism as an unfavorable predictor of malnutrition in patients with gastric cancer. The study group consisted of 220 gastric cancer patients treated at Affiliated Jinhua Hospital, Zhejiang University School of Medicine. Malnutrition was mainly assessed by the Global Consensus on Malnutrition Diagnostic Criteria (GLIM). DNA was extracted from peripheral leukocytes of whole blood samples using an animal DNA extraction kit. DNA was amplified using a 1.1× T3 Super PCR mixture and genotyped using SNP1 software. There are three major genetic polymorphisms in TNF-α. Among the 220 patients with gastric cancer, there were 7 patients with the CC genotype, 61 with the CT genotype and 152 with the TT genotype. Compared to patients with the TT genotype, patients with the C allele had an approximately 2.5-fold higher risk of developing malnutrition (p = 0.003; OR = 0.406). On the basis of multivariate analysis, patients with the CC genotype had an approximately 20.1-fold higher risk of developing malnutrition (p = 0.013; OR = 20.114), while those with the CT genotype had an almost 3.7-fold higher risk of malnutrition (p = 0.002; OR = 3.218). SNP (-1,031 T/C) of the TNF-α may be a useful marker in the assessment of the risk of nutritional deficiencies in gastric cancer patients. Patients with gastric cancer carrying the C allele should be supported by early nutritional intervention, but more research is still needed to explore confirmation.

Implementing a Machine Learning Screening Tool for Malnutrition: Insights From Qualitative Research Applicable to Other Machine Learning-Based Clinical Decision Support Systems.

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. 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. 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. 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. 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.
