Providing adequate and balanced nutrition for preterm infants, especially extremely/very preterm infants, is the material basis for promoting their normal growth and development and improving long-term prognosis. Enteral nutrition is the best way to feed preterm infants. Previous systematic reviews have shown that using evidence-based standardized feeding management strategies can effectively promote the establishment of full enteral feeding, reduce the duration of parenteral nutrition, improve the nutritional outcomes of preterm infants, and not increase the risk of necrotizing enterocolitis or death. Based on relevant research in China and overseas, the consensus working group has developed 20 recommendations in 5 aspects including the goal of enteral nutrition, transitioning to enteral nutrition, stable growth period enteral nutrition, supplementation of special nutrients, and monitoring of enteral nutrition for preterm infants, using the Grading of Recommendations Assessment, Development and Evaluation. The aim is to provide recommendations for healthcare professionals involved in the management of enteral nutrition for preterm infants, in order to improve the clinical outcomes of preterm infants.

Objective: To investigate the protective effect of high-proportion breast milk feeding (>50%) on intraventricular hemorrhage (IVH) in very preterm infants (VPIs). Methods: This was a retrospective secondary analysis of a prospective multi-center study, which included 604 VPIs from six hospitals in eastern China between September 2019 and December 2020. The 604 VPIs were divided into two groups according to whether IVH occurred. High-proportion breast milk feeding was defined as breast milk accounting for 51-100% of the total feeding amount both within 7 days and throughout the hospitalization. The IVH grades and the rate of high-proportion breast milk feeding were analyzed. Furthermore, to explore the relationship between high-proportion breast milk feeding and IVH grading, the VPIs' general information, perinatal factors, growth, and nutritional status during hospitalization, and related complications were compared between the two groups. Results: High-proportion breast milk feeding was reported in 63.41% of the VPIs. Furthermore, IVH grades I-II and III-IV were noted in 39.73% (240/604) and 1.66% (10/604) of the VPIs, respectively. Univariate analysis revealed that IVH occurrence in VPIs is influenced by perinatal factors, invasive respiratory therapy, high-proportion breast milk feeding, start feeding with breast milk, the cumulative amount of early parenteral nutrition, postnatal complications, physical growth, and other factors (P < 0.05). After adjustments for gestational age, birth weight, and possible influencing factors through binary logistic regression analysis, the results revealed that high-proportion breast milk feeding and and start feeding with breast milk were associated with a lower total incidence of IVH. Further stratification showed that high-proportion breast milk feeding was associated with a lower incidence of grade I-II IVH. Similarly, after adjusting for the same factors, breast milk feeding >50% in the 1st week was associated with a decreased incidence of total IVH and further stratification showed that it was associated with a lower incidence of grade I-II IVH. Conclusion: High-proportion breast milk feeding and breast milk feeding more than 50% of total intake during the 1st week might be protective factors for IVH grade I-II in VPIs, which further verified the neuroprotective effect of breastmilk. In clinical practice, the construction of breastmilk banks should be strengthened, breast milk feeding should be encouraged in neonatal intensive care units, and efforts should be made to increase breast milk feeding rates to improve the outcomes of VPIs.

Background: Intensive care is of great significance for very low birth weight infants (VLBWI). The Yangtze River Delta is the most ecomonically developed area in China. However, there are few data on the care practices and survival of VLBWI in this region.Objectives: To investigate the prevalence, care practices and motality of VLBWI in Yangtze River Delta in China.Methods: A multi-center retrospective investigation study was conducted at five tertiary hospitals within the Yangtze River Delta in China from January to December 2017. Clinical data included the general characteristics of the infants and the mothers, clinical prognosis, care practices in NICUs was collected by trained research members.Results: During the study period, 1059 VLBWIs were included. Infants with birth weight < 750 g, 750-1000 g, 1000-1250 g and 1250-1500 g accounted for 2.3, 14.9, 34.8 and 47.8%, respectively. Premature rupture of membranes (17.8%) was the main cause of premature delivery. The catheterization rates of umbilical vein catheterization (UVC) and peripherally inserted central catheter (PICC) were 25.0 and 64.4%, respectively. The duration of parenteral nutrition was 27.0 ± 19.5 d, the meantime of feeding tube indwelling was 36.2 ± 24.2 d. The corrected gestational age of the infants who reached full oral feeding was 35.8 ± 2.7 weeks. The breast feeding rate in the investigated infants was 61.9%. The mortality rate of preterm infants was 3.4%. The incidence of main complications BPD, PDA, ROP, NEC and sepsis were 24.9, 29.9, 21.7, 9.4 and 13.3% respectively.Conclusions: Maternal and infant care practices need to be improved in the very preterm births. This study provides a baseline for the improvement in the further study. [ABSTRACT FROM AUTHOR]

Background: Congenital short‐bowel syndrome (CSBS) is a rare disorder characterized by retardation of intestinal development. However, it is still not well recognized at present. In this study, the etiological, clinical, and genetic characteristics of CSBS in China were analyzed. Methods: Nine infants with CSBS were recruited. Full‐thickness biopsy findings were evaluated by histopathology. Whole‐exome sequencing was performed to identify mutations in patients and their family members. All patients were followed up at >1 year of age. Results: Six of 9 infants had malrotation, and 2 patients had intestinal atresia. The average total small‐bowel length was 51.7 (40–75) cm. Coxsackie and adenovirus receptor‐like membrane protein (CLMP) mutations were found in 5 patients and were related to decreases in ileal goblet cells and mucous secretion. Among these 5 patients, 3 shared the same mutation (c. 206G>A p.R69H), 1 patient had an exon 3–5 deletion, and 1 patient had the C.655T>G, p.Cys219Gly, and C.389‐2A>C. Another case carried a loss‐of‐function mutation in filamin A (FLNA). In the other 3 patients, no pathogenic mutations in genes related to intestinal development were found. The rate of catheter‐related bloodstream infection was 4.3 per 1000 catheter days, and intestinal failure–associated liver disease (IFALD) was 77.8%. The median follow‐up duration was 24.1 months. Eight patients were weaned off parenteral nutrition (PN). Six patients still exhibited malnutrition during follow‐up. Conclusions: Infants with CSBS often need long‐term PN and remain at risk of SBS‐related complications. CLMP and FLNA mutations are associated with CSBS in the Chinese population.

Purpose: Vitamins and trace elements are essential nutrients for growth and intestinal adaptation in children with short bowel syndrome (SBS). This study aimed to assess micronutrients' status during and after weaning off PN in pediatric SBS. Methods: This retrospective study evaluated the follow-up of 31 children with SBS between Jan 2010 and Sep 2019. Clinical data were reviewed from the patients' electric medical record. Serum electrolytes, trace elements, vitamin B12, vitamin D, and folate concentrations were collected before and after enteral autonomy. Results: Thirty-one SBS cases were reviewed (median onset age 11 days after birth, 51.6% boys, mean PN duration 4 months, and mean residual small intestine length 58.2 cm). Median duration of follow-up was 10 months (interquartile range [IQR]: 4, 19). The common micronutrient deficiencies were zinc (51.6%), copper (38.7%), vitamin D (32.3%), and phosphorus (25.8%) after the transition to EN. The proportion of patients deficient in vitamin D decreased dramatically from 93.5% to 32.3% (P < 0.001), and serum concentrations of vitamin D increased significantly (27.4 ± 12.3 vs. 60.3 ± 32.9 nmol/l, P = 0.03) after achieving full enteral feeding more than 1 month. Additionally, serum magnesium levels significantly increased (0.76 ± 0.17 vs. 0.88 ± 0.14 mmol/l, P = 0.03). Hemoglobin levels elevated significantly after weaning off PN (104.3 ± 10.7 vs. 117.8 ± 13.7 g/l, P = 0.03). Conclusions: Micronutrient deficiencies remain a common problem in pediatric SBS through intestinal rehabilitation. Therefore, we strongly recommend supplementation of more vitamin D and trace elements (zinc, copper, and phosphorus) under regular monitoring during long-term intestinal rehabilitation.

Objectives. This study aimed to investigate the current status of nutrition-support therapies by emergency physicians in China and to provide an evidence-based case to improve the regulation of enteral and parenteral nutrition-support therapies. Methods. Physicians from the Emergency Branch of the China Geriatrics Society were enrolled in the present survey. A questionnaire related to nutrition-support therapy, including the time, location, ways, indications, complications, and nutrition-support training for physicians was answered. Results. 527 questionnaires were collected from over 300 hospitals in 25 provinces of China. The time to initiation of emergency nutrition support was often delayed. Furthermore, the treatment intensity and standardized training of physicians are weaknesses concerning nutrition support. Treatment standardization has been significantly improved, including blood glucose monitoring, precaution and management of complications, and the use of immunomodulators. Conclusions. Emergency physicians should pay attention to early identifying and providing nutrition support to those patients who need it. Finally, standardized training should be developed for emergency nutrition-support therapy. [ABSTRACT FROM AUTHOR]

Purpose: The goal of this study was to analyze long-term outcome of various pediatric short bowel syndrome (SBS) at an intestinal rehabilitation center in China., Methods: One hundred and fifty-seven children with SBS were enrolled in this study from October 1988 to July 2019. Their long-term follow-up outcome was analyzed according to the age of disease onset, parenteral nutrition (PN) duration, and anatomic types of short bowel, respectively. The clinical characteristics, which included demographics, the length of residual small bowel, PN duration, PN dependence, SBS-related complications such as IF-related liver disease (IFALD), catheter-related bloodstream infection (CRBI), and mortality were compared among the groups., Results: The main etiology for SBS were intestinal atresia, NEC, and volvulus. Five of 157 patients did not wean off PN. The incidence of IFALD and CRBI was 24.2 and 22.3%, respectively. Sixteen cases died because of infection and liver failure and eight patients lost to follow-up. The survival rate of the 157 patients was 84.7%. PN duration was longer in the infants and children group (284 ± 457 d vs. 110 ± 64 d, P = 0.021; R = 0.264, P = 0.001) and more patients did not wean off PN than in the neonates group (11.6% vs. 0, P = 0.001; R = 0.295, P < 0.001). Patients with PN with a duration of longer than 90 days had more CRBIs (30.6%, P = 0.025; R = 0.236, P = 0.003). Additionally, the rate of CRBI was higher in patients with stoma (30.0%, P = 0.032). There was no difference in mortality among the groups. In five PN dependence patients, none was SBS onset in neonates., Conclusion: Pediatric patients with SBS could achieve favorable long-term survival and enteral autonomy. Different standards of SBS classification such as the age of disease onset, PN duration, and anatomic types of short bowel did not impact the overall mortality of pediatric SBS. Prolonged PN duration positively correlated with the age of disease onset and the incidence of CRBI. Patients with the complete continuity of intestinal tract suffered less from CRBI.
