BACKGROUND: Appropriate nutritional management in critically ill patients positively impacts prognosis. This study evaluated the effectiveness of a dietitian-led early enteral nutrition protocol in an intensive care unit (ICU).
METHODS: This retrospective analysis of prospectively collected data included patients who stayed in the emergency ICU (EICU) for at least 5 days between April 2021 and May 2022. Patients were divided into control and early support groups based on the implementation of the early enteral nutrition protocol in November 2021.
RESULTS: The time to start enteral nutrition after admission was significantly shorter in the early support group (41.9 h) than in the control group (59.8 h). The early support group (n = 58) also had higher nutritional sufficiency rates than the control group (n = 56) and a lower incidence of diarrhea (10% vs. 37.5%).
CONCLUSIONS: The dietitian-led early nutritional support system effectively reduced the time to enteral nutrition initiation, improved nutritional sufficiency rates, and decreased the incidence of diarrhea in the EICU.

This study examines the effectiveness of nasojejunal and intravenous nutrition in supplementing nutrition for patients with upper gastrointestinal (GI) strictures and analyzes the risk factors associated with malnutrition to provide references for clinical nutrition strategies. A retrospective analysis was conducted on 71 patients with upper GI strictures caused by esophageal and gastric cancers, who received nutritional support from January 2015 to January 2023. Out of these, 53 patients had complete baseline and follow-up data. We collected general clinical and perioperative data for comparison of the efficacy between nasojejunal nutrition and intravenous nutrition. Risk factors for malnutrition were analyzed using univariate and multivariate logistic regression. Malnutrition occurred in 24.53% (13/53) of the patients with upper GI strictures. The incidence of malnutrition was 6.06% (2/33) in the nasojejunal nutrition group compared to 55.00% (11/20) in the intravenous nutrition group, with a statistically significant difference (P < .001). Univariate and multivariate regression analyses identified diabetes (P < .001), initial blood K (P = .011), pathological staging (P < .001), and pathological grading (P < .001) as risk factors for malnutrition in patients with upper GI strictures. Diabetes (P = .028), initial blood K (P = .018), and pathological staging (P = .011) were found to be independent risk factors. Nasojejunal nutrition results in a lower incidence of malnutrition compared to intravenous nutrition in patients with upper GI strictures. Diabetes, initial blood K, pathological staging, and pathological grading are risk factors for malnutrition, with diabetes, initial blood K, and pathological staging serving as independent risk factors.

OBJECTIVE: Gastric tube feeding and postpyloric tube feeding are two common forms of enteral nutrition in critically ill patients. This study aimed to compare the efficacy and safety of gastric tube feeding with that of postpyloric tube feeding in critically ill patients.
METHODS: PubMed, Embase, and Cochrane Library were systematically searched for eligible trials from their inception until March 2023. Relative risks (RRs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs) were used to estimate categorical and continuous outcomes using the random-effects model.
RESULTS: Sixteen trials involving 1,329 critically ill patients were selected for the final meta-analysis. Overall, we noted that gastric tube feeding showed no significant difference from post-pyloric tube feeding in mortality (p = 0.891), whereas the risk of pneumonia was significantly increased in patients who received gastric tube feeding (RR: 1.45; p = 0.021). Furthermore, we noted that gastric tube feeding was associated with a shorter time required to start feeding (WMD: -11.05; p = 0.007).
CONCLUSIONS: This research revealed that initiating feeding through the gastric tube required less time compared to postpyloric tube feeding. However, it was also associated with a heightened risk of pneumonia among critically ill patients.

BACKGROUND: Urine sodium concentration has been suggested as a marker to guide enteral sodium supplementation in preterm infants; however, no previous data have demonstrated relationships between urine sodium concentration and postnatal growth.
METHODS: We performed a single-center retrospective cohort study on 224 preterm infants admitted to the neonatal intensive care unit at the Children\'s Hospital of Georgia between January 2010 and July 2022. Spot urine sodium was measured in preterm infants (<34 weeks postmenstrual age [PMA]) between days of life (DOLs) 7 and 28. Our exposure of interest was spot urine sodium concentration (milliequivalents per liter) obtained between postnatal days 7 and 28, and our primary outcome was weight velocity (grams per kilograms per day) determined at DOL 28. Statistical relationships were assessed by multivariate analysis with subgroup comparisons by Student t test and analysis of variance.
RESULTS: In 224 preterm infants (199 ± 17 days, 56% male, 71% Black), urine sodium concentration did not associate with weight velocity at DOL 28 and 36 weeks PMA. Urine sodium concentration was weakly associated with gestational age at birth, and Black preterm infants had higher urine sodium values when compared with \"other,\" but not White preterm infants.
CONCLUSIONS: Spot urine sodium during the first month of life does not associate with weight velocity at DOL 28 or 36 weeks PMA.

The validity of the traditional nutritional assessment tools in intensive care settings might be compromised when the patient has conditions such as oedema and inflammation. Ultrasound (US) is considered a non-invasive, bedside tool that can be utilized to assess changes in muscle mass. Hence, US could guide healthcare practitioners in identifying the varying degrees of malnutrition and adjusting the nutritional prescription accordingly. This review discusses the currently available data regarding the feasibility and practicality of using US measurements in intensive care settings. Overall, the data suggest that using US as part of the standard anthropometric assessment for critically ill patients is a promising tool to track variations in muscle mass. This has the potential to enhance nutritional prescription and tailor the provision of protein and energy to critically ill patients based on their lean body mass measurements. Therefore, it is recommended to train dietitians on utilizing US for body composition measurements.

The practice of administering blended food via enteral feeding tubes has been growing in popularity in recent years. Concerns have been raised as this practice was perceived to increase risk of gastrointestinal intolerance, allergic reactions, nutritional insufficiency, tube blockages, and infection compared with using commercial enteral feed (CEF), the gold standard, as well as risk of litigation against the professional due to their support of practice that is not evidence-based. However, research has shown that the physical, social and emotional benefits from receiving blended diet may outweigh the previously suggested risks. Guidance has been updated to encourage discussions around blended diet while informing the tube-fed individuals, families and carers of potential risks, potential benefits, barriers, considerations for training, safety and contraindications.

Chronic kidney disease (CKD) encompasses diverse conditions such as congenital anomalies, glomerulonephritis, and hereditary nephropathies, necessitating individualized nutritional interventions. Early detection is pivotal due to the heightened risk of adverse outcomes, including compromised growth and increased healthcare costs. The nutritional assessment in pediatric CKD employs a comprehensive, multidisciplinary approach, considering disease-specific factors, growth metrics, and dietary habits. The prevalence of malnutrition, as identified through diverse tools and guidelines, underscores the necessity for regular and vigilant monitoring. Nutritional management strategies seek equilibrium in calorie intake, protein requirements, and electrolyte considerations. Maintaining a well-balanced nutritional intake is crucial for preventing systemic complications and preserving the remaining kidney function. The nuanced landscape of enteral nutrition, inclusive of gastrostomy placement, warrants consideration in scenarios requiring prolonged support, with an emphasis on minimizing risks for optimized outcomes. In conclusion, the ongoing challenge of managing nutrition in pediatric CKD necessitates continuous assessment and adaptation. This review underscores the significance of tailored dietary approaches, not only to foster growth and prevent complications but also to enhance the overall quality of life for children grappling with CKD.
