Poor nutrition doubles post-COVID-19 syndrome risk in cancer patients: insights from a Chinese multicentre study

BackgroundSince 2019, approximately 760 million SARS-CoV-2 cases have been reported globally, with post-COVID-19 syndrome posing significant challenges for cancer patients due to their immunosuppressed status and poor nutritional conditions. The role of nutritional status in influencing their infection risk and post-COVID-19 outcomes remains unclear, underscoring the need for targeted research and strategies.ObjectiveTo investigate the impact of baseline nutritional status on SARS-CoV-2 infection and the risk of post-COVID-19 syndrome in cancer patients.MethodsA multicenter cross-sectional study was conducted from December 2022 to June 2023 in four tertiary hospitals across China. Cancer inpatients aged 18 years and older were enrolled and classified into two groups based on their Nutritional Risk Screening (NRS) scores. The correlation between SARS-CoV-2 infection, post-COVID-19 syndrome and nutritional status were analyzed using multivariable logistic regression.ResultsAmong 834 eligible cancer patients, 10.8% were in the high nutritional risk group (NRS ≥ 3). The prevalence of SARS-CoV-2 infection was 58.8% (95% confidence interval, CI: 56.8–60.8%), and post-COVID-19 syndrome was 21.0% (95% CI: 10.4–14.4%). After adjusting for confounding factors, the high nutritional risk group had a significantly higher prevalence of post-COVID-19 syndrome compared to the low nutritional risk group (32.7% vs. 19.5%, AOR: 2.37, 95% CI: 1.23–4.54, p = 0.010). However, no significant difference in SARS-CoV-2 infection rates was found between the two groups (61.1% vs. 58.5%, AOR: 1.12, 95% CI: 0.70–1.80; p = 0.634).InterpretationPoor baseline nutritional status in cancer patients is associated with a higher prevalence of post-COVID-19 syndrome, providing preliminary information on post-COVID-19 syndrome in this population. These findings underscore the importance of adequate nutritional management in cancer patients, particularly during pandemic recurrences.

Prognostic value of serum 25-hydroxyvitamin D levels and malnutrition status on postoperative complications in patients following laryngectomy with neck dissection.

Postoperative complications (PCs) following total laryngectomy remain a significant challenge, with recent investigations directed toward the impact of nutrition status and vitamin D deficiency. To elucidate the association between preoperative vitamin D level status, malnutrition risk score, and surgical and survival outcomes in patients with advanced laryngeal cancer following total laryngectomy. Prospective cohort study. Sixty-four patients with advanced laryngeal carcinoma treated with total laryngectomy were included in the study. Serum levels of 25(OH) D3 were measured employing a commercial chemiluminescent immunoassay kit, while nutrition status was evaluated using the nutrition risk index (NRI) and Malnutrition universal screening tool (MUST). The mean serum 25(OH) D level was 37.1 ± 19.4 nmol/L (range 11.0-100.6 nmol/L), with 47% of patients exhibiting vitamin D deficiency and 31% displaying insufficiency. Medium/high MUST score had 53% of patients, and moderate/severe NRI was verified in 48% of patients. Univariate logistic regression analysis identified MUST score, GPS score, neutrophil-to-lymphocyte ratio, and circulating 25(OH) D levels as predictive for the occurrence of PCs. In multivariate analysis, MUST score and circulating 25(OH) D levels remained significantly associated with PCs. Patients with high nutrition risk had significantly lower two-year OS rates compared to the medium and low nutrition risk groups, respectively (30% vs. 62% and 83%, p = 0.010). Early identification of malnourished or patients with vitamin D deficiency and those who would benefit from specific nutritional support could be beneficial for minimizing the risk of development of surgical complications and help improve our clinical outcomes.

Dietary strategies and nutritional supplements in the management of heart failure: a systematic review.

Heart failure (HF) is a syndrome of increased intracardiac pressure or decreased cardiac output. There is a lack of conclusive evidence to recommend the regular use of any dietary supplement in patients with HF. However, certain studies have shown nutritional interventions to be beneficial for patients with HF. Therefore, the purpose of this systematic review was to understand and map the updates of dietary interventions and nutritional supplementation measures related to patients with HF over the past 5 years. A systematic review. The PubMed, Web of Science, Scopus, and Cochrane Library databases were searched for randomized clinical trials on the association between dietary interventions and nutritional supplements and HF published between 2018 and 2023. A total of 1755 documents were retrieved, of which 19 were finalized for inclusion. The findings suggest that individualized nutritional support reduces mortality and risk of major cardiovascular events in chronic heart failure inpatients at high nutritional risk. The Mediterranean diet improves functionality, quality of life, and cardiac function. Additionally, supplementation with thiamine, ubiquinol, D-ribose, and L-arginine enhances left ventricular ejection fraction. Probiotic yogurt may effectively improve the inflammatory and antioxidative status of chronic heart failure. Whey protein and melatonin have a positive effect on improving endothelial function in HF patients. Certain dietary interventions and nutritional supplements may provide some benefit to patients with HF. However, there is no relevant definitive evidence on the impact of nutritional interventions on the prognosis of HF, and more high-quality clinical trials are needed for further in-depth studies.

The impact of web-based education provided to parents on the nutritional risk of preschoolers: A quasi-experimental study.

The purpose of this study was to evaluate the effectiveness of web-based nutrition education for parents of preschool children in reducing nutritional risk. The study was conducted in a one-group pretest-posttest quasi-experimental design. Parents of 3-5-year-old children from 11 preschools in Istanbul participated. They underwent a web-based nutrition education program. The NutriSTEP assessment tool was used to evaluate the nutritional risk score as a pretest assessment, followed by the training program. Posttests were conducted at 1- and 3-month intervals. Before the intervention, 55.8% of the children exhibited high nutritional risk. After the intervention, this percentage decreased significantly at the 1-month and 3-month follow-ups, with 94.2% and 93.6% of the children classified as low risk, respectively. The analysis also revealed significant associations between children's eating behaviours and factors such as maternal education, family income and family structure. As a result, web-based nutrition education was effective in reducing nutritional risk among preschool children. The findings underscore the importance of using technology for nutrition interventions, especially in diverse populations. The training program's simple, short and understandable video increased participants' interest in the training and encouraged regular follow-up.

Nutrition Rehabilitation in Oncopathology: Opportunities and Prospects

Nutritional corrective support is an integral component of rehabilitation programs in the perioperative period for oncological pathology. The aim of this study was to evaluate the effectiveness of including remaxol in the rehabilitation treatment regimen for gastroenterological cancer patients. Material and methods. The treatment results of 42 patients with gastric outlet tumors and small intestine tumors were retrospectively analyzed. Remaxol was included in the adjuvant therapy for patients in the main (I, N=22) group: intravenously 400 ml at a rate of 40–80 drops/min (2–4 ml/min) once a day for 10 days. Patients in the comparison group (II, N= 20) received traditional nutritional therapy. The study used both traditional clinical diagnostic methods and methods for assessing the risks of nutritional deficiency and the rehabilitation potential of the body, its adaptive capabilities, and disease prognosis. Results. All patients showed signs of severe nutritional deficiency, endotoxemia, intoxication, and hepatotoxicity. Liver detoxification parameters were better in patients who received remaxol as an adjuvant therapy than in the comparison group. Conclusions. Cancer patients with a high nutritional risk and moderate to high nutritional deficiency are at a higher risk of developing toxic complications requiring adjuvant therapy. The inclusion of remaxol in adjuvant therapy reduced the severity of hepatotoxic reactions in these patients. The data obtained made it possible to recommend its inclusion in treatment regimens for patients with this pathology.

Low triiodothyronine is associated with high risk of malnutrition and poor functional status in subacute stroke patients

Background and AimsStroke patients may exhibit low thyroid hormone (TH) levels and disease-related malnutrition, both potentially affecting clinical status; their relationships remain unexplored. This study aimed to evaluate TH concentrations in subacute stroke patients and investigate the relationships between TH levels, nutritional risk, and functional status. Methods and ResultsEarly subacute stroke patients admitted to a rehabilitation unit were assessed using various nutritional screening tools (Geriatric Nutritional Risk Index-GNRI, Prognostic Nutritional Index-PNI, and Controlling Nutritional Status-CONUT score) and with the Global Leadership Initiative on Malnutrition (GLIM) criteria.Thyroid-Stimulating Hormone (TSH), free Tetraiodothyronine-Thyroxine (fT4) and free Triiodothyronine (fT3) levels were determined. Functional and cognitive status was evaluated using different scales. Associations between altered THs and nutritional status were examined through univariate/multivariate analyses and ROC analyses.Among 264 patients (age 72.0±10.5 yrs), significant correlations emerged between fT3 and nutritional risk and functional tests (mostly p<0.001). The prevalence of high nutritional risk determined by GNRI, PNI and CONUT increased from higher to lower fT3 tertiles. Lower fT3 levels were observed in patients at high nutritional risk and with GLIM-based malnutrition. fT3 exhibited reasonable predictive power for high nutritional risk (particularly PNI: AUC 0.769, 95%CI 0.702-0.836, p<0.001). Multivariate logistic regression identified nutritional risk (p<0.001) and time from stroke onset as predictors of low fT3 values. ConclusionAltered fT3 levels in early subacute stroke patients correlate with high nutritional risk and poor functional status. Low fT3 values upon admission for stroke rehabilitation may serve as a further parameter to be considered in patients at high nutritional risk.

The correlation of CT-derived muscle density, skeletal muscle index, and visceral adipose tissue with nutritional status in severely injured patients.

This study explored if computerized tomography-derived body composition parameters (CT-BCPs) are related to malnutrition in severely injured patients admitted to the Intensive Care Unit (ICU). This prospective cohort study included severely injured (Injury Severity Score ≥ 16) patients, admitted to the ICU of three level-1 trauma centers between 2018 and 2022. Abdominal CT scans were retrospectively analyzed to assess the CT-BCPs: muscle density (MD), skeletal muscle index (SMI), and visceral adipose tissue (VAT). The Subjective Global Assessment was used to diagnose malnutrition at ICU admission and on day 5 of admission, and the modified Nutrition Risk in Critically ill at admission was used to assess the nutritional risk. Seven (11%) of the 65 analyzed patients had malnutrition at ICU admission, increasing to 23 patients (35%) on day 5. Thirteen (20%) patients had high nutritional risk. CT-BCPs were not related to malnutrition at ICU admission and on day 5. Patients with high nutritional risk at admission had lower MD (median (IQR) 32.1 HU (25.8-43.3) vs. 46.9 HU (37.7-53.3); p < 0.01) and higher VAT (median 166.5 cm2 (80.6-342.6) vs. 92.0 cm2 (40.6-148.2); p = 0.01) than patients with low nutritional risk. CT-BCPs do not seem related to malnutrition, but low MD and high VAT may be associated with high nutritional risk. These findings may prove beneficial for clinical practice, as they suggest that CT-derived parameters may provide valuable information on nutritional risk in severely injured patients, in addition to conventional nutritional assessment and screening tools.

ESPEN practical guideline on clinical nutrition in hospitalized patients with acute or chronic kidney disease

Hospitalized patients often have acute kidney disease (AKD) or chronic kidney disease (CKD), with important metabolic and nutritional consequences. Moreover, in case kidney replacement therapy (KRT) is started, the possible impact on nutritional requirements cannot be neglected. On this regard, the present guideline aims to provide evidence-based recommendations for clinical nutrition in hospitalized patients with KD. The standard operating procedure for ESPEN guidelines was used. Clinical questions were defined in both the PICO format, and organized in subtopics when needed, and in non-PICO questions for the more general topics. The literature search was from January 1st, 1999 until January 1st, 2020. Each question led to one or more recommendation/statement and related commentaries. Existing evidence was graded, as well as recommendations and statements were developed and agreed upon in a multistage consensus process. The present guideline provides 32 evidence-based recommendations and 8 statements, defining how to assess nutritional status, how to define patients at risk, how to choose the route of feeding, and how to integrate nutrition with KRT. In the final online voting, a strong consensus was reached in 84% at least of recommendations and 100% of statements. The presence of KD in hospitalized patients identifies a highly heterogeneous group of subjects with widely varying nutrient needs and intakes. Considering the high nutritional risk related with this clinical condition, an individualized approach consisting of nutritional status evaluation and monitoring, frequent evaluation of nutritional requirements, and careful integration with KRT should be planned to avoid both underfeeding and overfeeding. Practical recommendations and statements were developed, aiming at defining suggestions for everyday clinical practice in the individualization of nutritional support in this patient setting. Literature areas with scarce or without evidence were also identified, thus requiring further basic or clinical research.

Post-discharge complications and hospital readmissions are associated with nutritional risk and malnutrition status in a cohort of Canadian pediatric patients

BackgroundThis study constitutes a secondary analysis of a prospective cohort aiming to evaluate the potential correlation between nutritional risk and status at admission with the occurrence of post-discharge complications and hospital readmissions in children receiving care at high resource Centres.MethodsData was collected from 5 Canadian tertiary pediatric Centers between 2012 and 2016. Nutritional risk and status were evaluated at hospital admission with validated tools (STRONGkids and Subjective Global Nutrition Assessment [SGNA]) and anthropometric measurements. Thirty days after discharge, occurrence of post-discharge complications and hospital readmission were documented.ResultsA total of 360 participants were included in the study (median age, 6.1 years; median length of stay, 5 days). Following discharge, 24.1% experienced complications and 19.5% were readmitted to the hospital. The odds of experiencing complications were nearly tripled for participants with a high nutritional risk compared to a low risk (OR = 2.85; 95% CI [1.08–7.54]; P = 0.035) and those whose caregivers reported having a poor compared to a good appetite (OR = 2.96; 95% CI [1.59–5.50]; P < 0.001). According to SGNA, patients identified as malnourished had significantly higher odds of complications (OR, 1.92; 95% CI, 1.15–3.20; P = 0.013) and hospital readmission (OR, 1.95; 95% CI, 1.12–3.39; P = 0.017) than to those well-nourished.ConclusionsThis study showed that complications and readmission post-discharge are common, and these are more likely to occur in malnourished children compared to their well-nourished counterparts. Enhancing nutritional care during admission, at discharge and in the community may be an area for future outcome optimization.

Nutritional status affects immune function and exacerbates the severity of pulmonary tuberculosis.

To comprehensively evaluate the association and impact of nutritional status and immune function on the severity of pulmonary tuberculosis (PTB). This descriptive cross-sectional study involved 952 participants who were diagnosed with active PTB. Severe PTB involves three or more lung field infections based on chest radiography. Nutritional status was evaluated using various indicators, including body mass index (BMI), the nutritional risk screening score (NRS-2002), total protein (TP), prealbumin (PA), transferrin (TRF), and serum albumin (ALB) levels and the prognostic nutritional index (PNI). Immune dysfunction was defined as a CD4+ count <500 cells/µl or a CD4+/CD8+ ratio <1. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were also calculated. Multivariate logistic and generalized linear regression were used to assess the associations between nutritional status, immune function, the severity of PTB, and the number of infected lung fields, adjusting for age, sex, and diabetes. Mediation analysis was conducted to evaluate the extent to which immune function mediated the impact of nutritional status on the severity of PTB. Sensitivity analysis was performed to enhance the robustness of the results. Compared to those in the general PTB group, patients in the severe PTB group tended to be older men with diabetes. Higher nutritional risk, higher proportion of immune dysfunction and lower lymphocyte counts were observed in the severe group. BMI and the PNI were found to be protective factors, while PLR was identified as a risk factor for disease severity. Immune dysfunction and the PLR are mediators of the relationship between nutritional status and PTB severity. When BMI, the PNI, and the PLR were combined with traditional clinical indicators, these parameters showed promising diagnostic value, and the AUC reached 0.701 (95% CI: 0.668-0.734). The findings suggest that nutritional status is significantly associated with the severity of PTB, and immune function mediates the effects of nutritional status on the severity of PTB. Maintaining adequate BMI, PNI levels, and immune function or reducing PLR levels helps reduce the risk of severe PTB.

Chinese expert consensus on perioperative nutritional support for elderly surgical patients (2024)

The increasing aging population in China leads to an increase in the number of elderly patients undergoing surgical procedures. Elderly patients are characterized with conditions such as multiple comorbidities, high nutritional risk, frailty, decreased organ function, etc. Nutritional support is one of the most significant elements in the perioperative period of elderly surgical patients. Currently, there is a lack of guidelines or expert consensus on nutritional support. To promote the standardized development of clinical work in this field, the Geriatric Surgery Professional Committee of the Chinese Research Hospital Association gathered experts and formulated relevant recommendations for perioperative nutritional therapy for elderly surgical patients based on existing research evidence. This consensus included several parts: preoperative nutritional assessment, indications, goals, ingredients and approaches of perioperative nutritional support, nutritional complications and management, nutritional intervention for surgical complications, and nutritional follow-up. It is expected to provide valuable suggestions for standardizing nutritional support for elderly surgical patients.

Association of Nutritional Risk Index With Infection-Related Hospitalization and Death After Hospitalization in Patients Undergoing Maintenance Hemodialysis

Patients undergoing dialysis frequently experience hospitalization due to cardiovascular disease (CVD) and infection. This population is also at high risk of rehospitalization and subsequent death. In addition to serious outcomes, hospitalization incurs substantial medical cost. Prevention of hospitalization is accordingly an urgent matter. Here, we examined whether nutritional disorder was associated with hospitalization and subsequent death. The study was conducted under a prospective design using data from the Japanese Dialysis Outcomes and Practice Pattern Study. The exposure was the Nutritional Risk Index for Japanese Hemodialysis (NRI-JH), through which patients were divided into low-, medium-, and high-risk groups, with the low-risk group as referent. The primary outcome was CVD-related or infection-related hospitalization. Secondary outcome was all-cause mortality. For exploratory analyses, the associations of baseline or latest NRI-JH just before hospitalization, with death after hospitalizations, were examined. Of 4021 patients, 566 patients had CVD-related hospitalization and 375 had infection-related hospitalization during a median follow-up of 2.6years. NRI-JH at baseline was significantly associated with infection-related hospitalization but not with CVD-related hospitalization, in multivariable Cox models (hazard ratio [HR] 1.46, 95% confidential interval [CI]: 1.09 to 1.97, P=.012 for medium-risk vs. low-risk group) (HR 2.46, 95% CI: 1.81 to 3.35, P<.001 for high-risk vs. low-risk group). NRI-JH was also associated with all-cause mortality. In addition, the baseline and latest high-risk NRI-JH groups were significantly associated with death after both CVD-related and infection-related hospitalizations. A higher nutritional risk as evaluated by NRI-JH was associated with infection-related hospitalization but not with CVD-related hospitalization. However, NRI-JH was significantly associated with death after both CVD-related and infection-related hospitalizations, suggesting that nutritional risk may be separately involved in hospitalization or subsequent death. NRI-JH may be useful in the planning of individual care to improve outcomes.

Nutritional Indices Predict All Cause Mortality in Patients with Multi-/Rifampicin-Drug Resistant Tuberculosis.

Multidrug- and rifampicin-resistant tuberculosis (MDR/RR-TB) with high mortality remains a public health crisis and health security threat. This study aimed to explore the predictive value of nutritional indices for all-cause mortality (ACM) in MDR/RR-TB patients. We retrospectively recruited MDR/RR-TB patients between January 2015 and December 2021, randomly assigning them to training and validation cohorts. Patients were divided into high nutritional risk groups (HNRGs) and low nutritional risk groups (LNRGs) based on the optimal cut-off value obtained from receiver operating characteristic (ROC) analyses of the hemoglobin-albumin-lymphocyte-platelet (HALP) score, prognostic nutritional index (PNI), and controlling nutritional status (CONUT) score. In the training cohort, Kaplan-Meier survival curves and Log rank tests were used to compare overall survival (OS) between the groups. Cox risk proportion regression analyses were used to explore the risk factors of ACM in patients with MDR/RR-TB. The predictive performance of ACM was assessed using area under the curve (AUC), sensitivity and specificity of ROC analyses. A total of 524 MDR/RR-TB patients, with 255 in the training cohort and 269 in the validation cohort, were included. Survival analyses in the training cohort revealed significantly lower OS in the HNRGs compared to the LNRGs. After adjusting for covariates, multivariate analysis identified low HALP score, low PNI and high CONUT score were independent risk factors for ACM in MDR/RR-TB patients. ROC analyses demonstrated good predictive performance for ACM with AUCs of 0.765, 0.783, 0.807, and 0.811 for HALP score, PNI, CONUT score, and their combination, respectively. Similar results were observed in the validation set. HALP score, PNI, and CONUT scores could effectively predict ACM in patients with MDR/RR-TB. Hence, routine screening for malnutrition should be given more attention in clinical practice to identify MDR/RR-TB patients at higher risk of mortality and provide them with nutritional support to reduce mortality.

Effectiveness and safety of combined nimotuzumab and S-1 chemotherapy with concurrent radiotherapy for locally advanced esophageal cancer in malnourished and elderly patients: A prospective phase II study.

Definitive chemoradiotherapy (dCRT) is the standard treatment for unresectable locally advanced esophageal cancer. However, this treatment is associated with substantial toxicity, and most malnourished or elderly patients are unable to complete this therapy. Therefore, there is a need for a more suitable radiotherapy combination regimen for this population. This study was aimed to evaluate the efficacy and safety of a combination regimen comprising chemotherapy with nimotuzumab and S-1 and concurrent radiotherapy for patients with fragile locally advanced esophageal cancer with a high Nutritional Risk Screening 2002 (NRS-2002) score. Eligible patients with unresectable esophageal carcinoma who had an NRS-2002 score of 2 or higher were enrolled. They were treated with S-1 and nimotuzumab with concurrent radiotherapy, followed by surgery or definitive radiotherapy. The primary endpoint was the locoregional control (LRC) rate. A total of 55 patients who met the study criteria were enrolled. After completion of treatment, surgery was performed in 15 patients and radiotherapy was continued in 40 patients. The median follow-up period was 33.3 [95% confidence interval (95% CI), 31.4-35.1)] months. The LRC rate was 77.2% (95% CI, 66.6%-89.4%) at 1 year in the entire population. The overall survival (OS) rate and event-free survival (EFS) rate were 57.5% and 51.5% at 3 years, respectively. Surgery was associated with better LRC [hazard ratio (HR)=0.16; 95% CI, 0.04-0.70; P=0.015], OS (HR=0.19; 95% CI, 0.04-0.80; P=0.024), and EFS (HR=0.25; 95% CI, 0.08-0.75; P=0.013). Most adverse events were of grade 1 or 2, and no severe adverse events occurred. For malnourished or elderly patients with locally advanced esophageal cancer, radiotherapy combined with nimotuzumab and S-1 is effective and has a good safety profile.

Social Factors Associated With Nutrition Risk in Community-Dwelling Older Adults in High-Income Countries: Protocol for a Scoping Review.

In high-income countries (HICs), between 65% and 70% of community-dwelling adults aged 65 and older are at high nutrition risk. Nutrition risk is the risk of poor dietary intake and nutritional status. Consequences of high nutrition risk include frailty, hospitalization, death, and reduced quality of life. Social factors (such as social support and commensality) are known to influence eating behavior in later life; however, to the authors' knowledge, no reviews have been conducted examining how these social factors are associated with nutrition risk specifically. The objective of this scoping review is to understand the extent and type of evidence concerning the relationship between social factors and nutrition risk among community-dwelling older adults in HICs and to identify social interventions that address nutrition risk in community-dwelling older adults in HICs. This review will follow the scoping review methodology as outlined by the JBI Manual for Evidence Synthesis and the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. The search will include MEDLINE (Ovid), CINAHL, PsycINFO, and Web of Science. There will be no date limits placed on the search. However, only resources available in English will be included. EndNote (Clarivate Analytics) and Covidence (Veritas Health Innovation Ltd) will be used for reference management and removal of duplicate studies. Articles will be screened, and data will be extracted by at least 2 independent reviewers using Covidence. Data to be extracted will include study characteristics (country, methods, aims, design, and dates), participant characteristics (population description, inclusion and exclusion criteria, recruitment method, total number of participants, and demographics), how nutrition risk was measured (including the tool used to measure nutrition risk), social factors or interventions examined (including how these were measured or determined), the relationship between nutrition risk and the social factors examined, and the details of social interventions designed to address nutrition risk. The scoping review was started in October 2023 and will be finalized by August 2024. The findings will describe the social factors commonly examined in the nutrition risk literature, the relationship between these social factors and nutrition risk, the social factors that have an impact on nutrition risk, and social interventions designed to address nutrition risk. The results of the extracted data will be presented in the form of a narrative summary with accompanying tables. Given the high prevalence of nutrition risk in community-dwelling older adults in HICs and the negative consequences of nutrition risk, it is essential to understand the social factors associated with nutrition risk. The results of the review are anticipated to aid in identifying individuals who should be screened proactively for nutrition risk and inform programs, policies, and interventions designed to reduce the prevalence of nutrition risk.

Comparative efficacy of peptide-based versus standard polymeric enteral nutrition in ICU patients at high nutritional risk: a multicenter randomized controlled trial

Within intensive care units (ICU), the administration of peptide-based formulas (PBF) may confer nutritional advantages for critically ill patients identified with heightened nutritional risk. This investigation aimed to ascertain the efficacy of PBF in comparison to standard polymeric formulas (SPF) among this patient cohort. A double-blind, randomized controlled trial was conducted across three ICUs, encompassing 63 adult patients characterized by elevated modified Nutrition Risk in Critically Ill (mNUTRIC) scores. Enrollment occurred promptly subsequent to ICU admission, with participants allocated to receive either PBF or SPF. Primary outcome was the duration to achieve caloric targets. Secondary outcomes involved the evaluation of mean daily gastric residual volume, mechanical ventilation period, infection rates within the ICU, length of hospitalization, mortality rates, nutritional status and inflammatory markers, specifically serum albumin and interleukin-6 levels. Patients in the PBF group reached their caloric targets more expeditiously compared to the SPF group (2.06 ± 0.43 days versus 2.39 ± 0.79 days; p = 0.03). No significant differences were discernible between the groups regarding gastric residual volume, duration of mechanical ventilation, ICU length of stay, mortality, or infection rates. Both cohorts exhibited minimal adverse effects and were devoid of any instances of abdominal distension. While not reaching statistical significance, the observed trends in albumin and interleukin-6 levels suggest a potential advantage of PBF utilization. The implementation of PBF enabled swifter attainment of caloric goals in ICU patients at high nutritional risk without adversely impacting other clinical parameters. Given its favorable tolerance profile and potential immunomodulatory properties, PBF may be considered a valuable nutritional intervention in this setting.Thai Clinical Trials Registry TCTR20220221006.

Comparison of two isocaloric parenteral nutrition regimens with different protein content - A propensity-score matched comparative study.

this study aimed to assess the effects of two isocaloric parenteral nutrition (PN) regimens with different protein content and non-protein calorie to nitrogen ratio (NPCNR) on the evolution of nutritional parameters and outcomes in adult inpatients. this was a retrospective quasi-experimental study performed in a 400-bed tertiary hospital. Adult inpatients were initially eligible if they had received ≥ 4 days of PN with NPCNR ≥ 100 or ≤ 90 in a period of three years. Patients were propensity-score matched to adjust for differences, resulting in two final cohorts: Cohort "Medium-P" included patients receiving PN with NCPCNR ≥ 100 and cohort "High-P", receiving PN with NCPCNR ≤ 90. The main variables were differences in plasma albumin, prealbumin, cholesterol, and lymphocyte count, days requiring PN, length of stay, and mortality at 90 days. 202 patients were finally recruited and divided into the two equal cohorts. Patients were mainly male (122; 60.4 %), surgical (149; 73.8 %), critically ill (100; 49.5 %), with high nutritional risk (141; 69.8 %) and with a neoplasm (145; 71.8 %). PN provided 25 kcal/kg/day, but protein intake was 0.25 g/kg/day higher in the "High-P" cohort. Baseline characteristics and biochemistry were not different between the two cohorts. The "High-P" cohort presented a smaller difference at the end of PN for lymphocytes, more days with hyperglycaemia, and more days requiring PN. The rest of variables did not differ. high doses of protein (lower NPCNR) did not present advantages compared to medium doses of protein (higher NPCNR) when providing isocaloric PN in adult inpatients.

USE OF NUTRIENT RISK IN CRITICALLY ILL SCORE TO ASSESS NUTRITIONAL RISK IN MECHANICALLY VENTILATED PATIENTS

Ensuring proper nutritional support is crucial for critically ill patients. This nutritional deficit is closely associated with heightened susceptibility to nosocomial infections, delayed wound healing, and an escalated risk of mortality. Objective: The objective of this study is to evaluate the effectiveness of the Nutrient Risk in Critically Ill (NUTRIC) score in assessing the nutritional risk of mechanically ventilated patients. Method: It is a cross-sectional study. It is conducted at the Department of Critical Care Medicine, Shifa International Hospital, Islamabad from 1st Jan 2024 to 30 May 2024. The calculated sample size was 381 selected by non-probability consecutive sampling. The study utilized the modified Nutritional Risk in the Critically Ill (mNUTRIC) score to assess nutritional risk in mechanically ventilated (MV) patients. Data will be analyzed using SPSS 24.0. A P value of ≤ 5 will be significant Result: The study included a total of 381 participants, with a mean age of 55.7 ± 17.5 years and, a BMI was 23.7 ± 3.5. 219 (57.48%) had low nutritional risk (NUTRIC score ≤4), while 162 (42.51%) had high nutritional risk (NUTRIC score ≥5). Patients in the high nutritional risk group had a longer stay in the intensive care unit (ICU), had fewer ventilator-free days and had higher mortality rates compared to those in the low nutritional risk group (8.5 ± 4.1 days vs. 5.2 ± 3.9 days, p-value &lt; 0.01). Conclusion: The study highlights the significance of the NUTRIC score as a valuable tool for the estimation of nutritional risk among mechanically ventilated patients in the ICU setting
