Preoperative exclusive enteral nutrition (EEN) improves nutritional status, reduces intestinal inflammation, and likely improves surgical outcomes. Crohn\'s disease exclusion diet with partial enteral nutrition (CDED) also reduces intestinal inflammation but its safety preoperatively is unknown. This single-blinded, multicentre, randomised controlled trial of three preoperative nutritional therapies aimed to assess the feasibility of recruiting and retaining patients and collecting primary and secondary effectiveness outcomes. Adults undergoing elective Crohn\'s disease surgery with a body mass index (BMI) > 18.5 kg/m2 and without significant weight loss were eligible to participate. Patients were randomly assigned to six weeks of preoperative EEN, CDED, or standard care. Feasibility, nutritional, radiological, and surgical outcomes were recorded. Over 18 months, 48 patients were screened, 17 (35%) were randomised, and 13/17 (76%) patients were retained in the intervention phase. It was feasible to collect primary and secondary effectiveness data; at day 30, three patients had Clavien Dindo Grade 2 complications, and 10 had no complications. Nutritional therapy adherence of patients retained in the study was high. Recruitment and retention of patients who need elective Crohn\'s disease surgery for preoperative nutritional therapy is possible, although a shorter duration may improve EEN completion. The impact on surgical outcomes should be assessed in a larger study.

OBJECTIVE: Hypophosphatemia occurs frequently. Enteral, rather than IV, phosphate replacement may reduce fluid replacement, cost, and waste.
METHODS: Prospective, randomized, parallel group, noninferiority clinical trial.
METHODS: Single center, 42-bed state trauma, medical and surgical ICUs, from April 20, 2022, to July 1, 2022.
METHODS: Patients with serum phosphate concentration between 0.3 and 0.75 mmol/L.
METHODS: We randomized patients to either enteral or IV phosphate replacement using electronic medical record-embedded program.
RESULTS: Our primary outcome was serum phosphate at 24 hours with a noninferiority margin of 0.2 mmol/L. Secondary outcomes included cost savings and environmental waste reduction and additional IV fluid administered. The modified intention-to-treat cohort comprised 131 patients. Baseline phosphate concentrations were similar between the two groups. At 24 hours, mean ( sd ) serum phosphate concentration were enteral 0.89 mmol/L (0.24 mmol/L) and IV 0.82 mmol/L (0.28 mmol/L). This difference was noninferior at the margin of 0.2 mmol/L (difference, 0.07 mmol/L; 95% CI, -0.02 to 0.17 mmol/L). When assigned IV replacement, patients received 408 mL (372 mL) of solvent IV fluid. Compared with IV replacement, the mean cost per patient was ten-fold less with enteral replacement ($3.7 [$4.0] vs. IV: $37.7 [$31.4]; difference = $34.0 [95% CI, $26.3-$41.7]) and weight of waste was less (7.7 g [8.3 g] vs. 217 g [169 g]; difference = 209 g [95% CI, 168-250 g]). C O2 emissions were 60-fold less for comparable phosphate replacement (enteral: 2 g producing 14.2 g and 20 mmol of potassium dihydrogen phosphate producing 843 g of C O2 equivalents).
CONCLUSIONS: Enteral phosphate replacement in ICU is noninferior to IV replacement at a margin of 0.2 mmol/L but leads to a substantial reduction in cost and waste.

UNASSIGNED: To explore a set of enteral nutrition therapy continuity management programs for intensive care unit patients based on the theoretical study of circadian rhythm mechanism.
UNASSIGNED: The control group followed routine nursing management. Patients in the experimental group were implemented with an enteral nutrition continuity management program, and their eating behavior was adjusted 3 days before the end of tube feeding. Food intake was intermittent at 2, 3, and 4 h on the first day, the second day, and the third day of intervention, respectively, and all patients stopped eating at night. Abdominal distension assessment, appetite assessment, application of gastric motility drugs, and patient satisfaction were compared between the two groups after tube feeding.
UNASSIGNED: Three days after the end of tube feeding, abdominal distention assessment, bowel sound auscultation, and appetite assessment were statistically different (P<0.05) between the two groups. There were differences in the first day (15 vs. 6, P<0.05), the second day (9 vs. 3, P<0.05), and the cumulative number (17 vs. 7, P<0.05) of gastrointestinal drugs, but no differences in the third day (2 vs. 1, P>0.05). There was a statistical difference in nursing intervention (6.0 vs. 7.0, P<0.05) and psychological nursing (6.0 vs. 7.0, P<0.05), but no statistical difference in health education, medical environment, and nursing attitude (P>0.05).
UNASSIGNED: Enteral nutrition continuity management program has a good preventive effect on the gastrointestinal symptoms of intensive care unit patients after the end of tube feeding.

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.

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.

BACKGROUND: Conflicting findings regarding the impact of High protein intake during the early phase in critically ill patients have been reported. Therefore, we aimed to assess the influence of higher early protein intake on the prognosis of critically ill patients.
METHODS: This randomized controlled trial involved 173 critically ill patients who stayed in the Intensive Care Unit/Emergency ICU (ICU/EICU) for at least 7 days. The Low group (n = 87) and High group (n = 86) received protein supplementation of 0.8 g/kg.d and 1.5 g/kg.d, respectively, within 1-3 days of enteral nutrition (EN) initiation, with both groups transitioning to 1.5 g/kg.d on the 4th day. The serum prealbumin (PA), blood urea nitrogen/creatinine, and rectus femoris muscle thickness and cross-sectional area of all patients was measured on the 1th, 3rd, 5th, 7th day, and the day of ICU/EICU discharge.
RESULTS: Patients in both Low and High groups showed no significant differences in age, APACHE II scores, or other demographic and baseline characteristics. There were also no significant differences in the primary outcome (28-day mortality rate) and secondary outcomes (incidence rate of refeeding syndrome and EN tolerance score) between the two groups. However, the Low group exhibited a significantly higher 28-day mortality rate (HR = 2.462, 95% CI: 1.021-5.936, P = 0.045) compared to High group, as determined by Cox proportional hazards models incorporating the time factor. The High group exhibited significantly shorter durations of mechanical ventilation and ICU stay compared to the Low group. Serum PA levels were higher, and rectus femoris muscle atrophy rates were lower in the High group. Furthermore, for septic patients, high protein intake significantly reduced the 28-day mortality rate despite a small sample size (n = 34).
CONCLUSIONS: Our study indicates that increasing early protein intake to 1.5 g/kg.d may be safe and help improve the nutritional status and prognosis of critically ill patients.

BACKGROUND: Vitamin D is necessary to develop healthy lungs and other organs early in life. Most infants born before 28 weeks\' gestation have low vitamin D levels at birth and a limited intake during the first month. Enteral vitamin D supplementation is inexpensive and widely used. The appropriate supplementation regimen for extremely preterm infants is controversial, and the effect of different regimens on their blood levels and outcomes is unclear.
METHODS: Randomized, blinded comparative effectiveness trial to compare two vitamin D supplementation regimens for inborn infants <28 weeks gestation or <1000 g birth weight at a large academic center in the United States. Infants are stratified by birth weight and randomized within 96 h after birth to either routine supplementation (400 IU/day with established feedings) or increased supplementation (800 IU/day with any feedings) during the first 28 days after birth. We hypothesize that the higher and early vitamin D dose (800 IU/day with early feeding) compared to placebo plus routine dose (400 IU/day with established feeding) will substantially increase total 25-hydroxyvitamin D3 levels measured as state-of-art at 1 month, reduce respiratory support at 36 weeks\' postmenstrual age (on an ordinal scale predictive of later adverse outcomes), and improve or at least not worsen other important secondary outcomes. The infants in the study will follow up at 22-26 months\' corrected age (~2 years) with blinded certified examiners to evaluate neurodevelopmental outcomes. The sample size of a minimum of 180 infants provides >90% power to detect a >95% posterior probability of a 33% increase in serum 25-hydroxy vitamin D3 and >80% power to detect a >80% posterior probability of a relative risk decrease of 20% of reducing respiratory support by intention-to-treat Bayesian analyses using a neutral prior probability.
CONCLUSIONS: Our study will help clarify the uncertain relationship of vitamin D supplementation and its associated serum metabolites to clinical outcomes of extremely preterm infants. Confirmation of our hypotheses would prompt reconsideration of the supplementation regimens used in extremely preterm infants and justify a large multicenter study to verify the generalizability of the results.

BACKGROUND: The incidence of clinically avoidable enteral nutrition interruptions is high. ICU nurses, as the implementers and monitors of enteral nutrition, have a close relationship between their cognitive level of enteral nutrition interruption and the incidence of enteral nutrition interruption. The level of ICU nurses\' cognition of enteral nutrition interruption and the key factors influencing the level of ICU nurses\' cognition of enteral nutrition interruption are not known.
OBJECTIVE: This study aims to explore the cognitive level of ICU nurses on enteral nutrition interruption and delve into the key factors that affect their cognitive level from the perspective of management.
METHODS: A sequential explanatory mixed methods research design was used.
METHODS: With the convenience sampling method, an online survey questionnaire was distributed to ICU nurses in Chongqing, and 336 valid questionnaires were collected. After the survey, ICU managers were invited to participate in qualitative interviews, in which 10 participants from five hospitals completed face-to-face individual semi-structured interviews and were analyzed with thematic analysis.
RESULTS: The survey found that ICU nurses had a good level of cognition towards enteral nutrition interruption but poor knowledge about the definition, causes, and consequences of enteral nutrition interruption, as well as negative attitudes toward active learning, assessment, and communication. And the longer work time in the ICU, joining the nutrition team, receiving systematic training, and acquiring relevant knowledge from academic journals more frequently were favorable to improving ICU nurses\' knowledge level of enteral nutrition interruption. Personal interviews further identified the key factors affecting their cognitive level, including (1) lack of knowledge, (2) lack of proactive thinking, (3) lack of enteral nutrition management programs, and (4) lack of quality management tools for enteral nutrition interruption.
CONCLUSIONS: Although ICU nurses demonstrate a relatively high level of cognition, there is still room for improvement. ICU administrators must take specific measures to improve the knowledge of ICU nurses, especially in non-tertiary hospitals, in order to prevent nurse-induced enteral nutrition interruption in all ICUs and improve medical quality.
BACKGROUND: Not applicable.

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.

UNASSIGNED: Enteral nutrition is beneficial for stroke patients with oral intake difficulties. However, it is time consuming and may interfere with routine medical care. Therefore, there is a clinical benefit if enteral nutrition can be safely administered in a short time. Although our retrospective study showed the safety of rapid administration, it remains unclear whether rapid administration of enteral nutrition is as safe as conventional administration.
UNASSIGNED: The randomized study of Enteral Nutrition with Rapid versus conventional administration in acute stroke patients (Rapid EN trial) aims to clarify the safety of rapid feeding of enteral nutrition compared with conventional feeding.
UNASSIGNED: This is an investigator-initiated, multicenter, prospective, randomized, open-label, blinded end-point clinical trial. Eligible criteria include acute stroke patients who have difficulty with oral intake defined as severe altered consciousness (Japan Coma Scale 10-300) or modified water swallowing test <4. The target enrollment is 700 patients, with 350 patients receiving rapid enteral nutrition at a rate of 100 mL in 5 min (Rapid EN group) and 350 patients receiving conventional enteral nutrition at a rate of 100 mL in 30 min (Conventional EN group).
UNASSIGNED: The primary outcome is the incidence of one or more complications of vomiting or diarrhea or pneumonia within 7 days would be non-inferior in the rapid EN group compared to the conventional EN group. Secondary outcomes were total time spent on enteral nutrition within 7 days from enteral nutrition, the incidence of vomiting, diarrhea and pneumonia within 3 or 7 days, and the rate of favorable clinical outcome.
UNASSIGNED: Since no previous reports have focused on the speed of administration, we felt it was necessary to prove the safety of rapid administration. If this study shows positive results, it will not only benefit patients, but also reduce the burden of medical care. We believe this study is novel and will be useful in clinical practice.
