Gastrointestinal dysbiosis refers to adverse alterations of the intestinal flora and is associated with several diseases, including necrotizing enterocolitis, late-onset sepsis in preterm infants as well as atopic disease, colic, diabetes, and diarrhea in term infants. The risk factors for gastrointestinal dysbiosis are preterm birth, cesarean section delivery, and formula feeding, in contrast to term birth infants, vaginal delivery and breast milk feeding. Probiotics have been used to restore synbiosis in infants with gastrointestinal dysbiosis. Probiotics inhibit colonization of pathogenic bacteria in the gastrointestinal tract, thereby improving the barrier function of the gastrointestinal tract, and the immune function. In preterm infants, probiotics reduce mortality as well as rates of necrotizing enterocolitis and late-onset sepsis. The combined use of probiotics such as Lactobacillus and Bifidobacterium and the combination of probiotics with prebiotics yield better outcomes in the prevention of necrotizing enterocolitis than those achieved with a single pro- or prebiotic strain. However, the routine use of probiotics has been hindered by the lack of pharmaceutical-quality products, and a definite effect has yet to be demonstrated in preterm infants with a birth weight <1,000 g. Therefore, to reduce the risk of necrotizing enterocolitis in preterm infants, probiotics should be provided along with breast milk and other strategies aimed at preventing gastrointestinal dysbiosis.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49543110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined the effect of incompletely administered antenatal corticosteroids on the neonatal pulmonary outcomes in late preterm infants.Methods: Late preterm infants (34+0 to 36+6 weeks gestational age) born at the Seoul National University Bundang Hospital from January 2019 to June 2020 were retrospectively enrolled. We excluded multiple births except twins, those with major congenital anomalies, deaths, or transfers to other hospitals. An incomplete course of antenatal corticosteroids was defined as one in which the first or the second dose of betamethasone was administered within 24 hours before delivery. The rates of neonatal pulmonary morbidities were compared between late preterm infants given incomplete courses antenatal corticosteroids and their peers who not given antenatal corticosteroids; these morbidities included respiratory distress syndrome and transient tachypnea of the newborn, assisted ventilation including invasive mechanical ventilation, nasal continuous positive airway pressure and high-flow nasal cannula, and admission to neonatal intensive care unit.Results: Logistic regression models were constructed while adjusting for factors which were significant in bivariate models. After adjusting for baseline maternal and neonatal characteristics, we found no significant differences in the rates of neonatal pulmonary morbidities, assisted ventilation, or admission to the neonatal intensive care unit between late preterm infants who received incomplete antenatal corticosteroid therapy and their peers who were not given any antenatal corticosteroids.Conclusion: Incompletely administered antenatal corticosteroids did not significantly alter the neonatal pulmonary outcomes in late preterm infants.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41397998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre- and postnatal factors were correlated and analyzed with postnatal clinical outcomes to determine the prognostic factors. Highest oxygenation index (OI) within 24 hours of birth was also calculated. Treatment strategy and outcome analysis of published literatures were also performed.Results: Overall survival rate of this cohort was 60%. Four patients were unable to undergo anesthesia and/or surgery. Three patients who commenced extracorporeal membrane oxygenation (ECMO) post-surgery were non-survivors. Compared to the survivor group, the non-survivor group had a significantly higher occurrence of pneumothorax on the first day, need for high-frequency ventilator and inhaled nitric oxide use, and high OI within the first 24 hours. The non-survivor group showed an early trend towards the surgery timing and a greater number of patch closures. Area under the receiver operating characteristic curve was 0.878 with a sensitivity of 76.2% and specificity of 92.9% at an OI cutoff value of 7.75.Conclusion: OI within 24 hours is a valuable predictor of survival. It is expected that the application of ECMO based on OI monitoring may help improve the opportunity for surgical repair, as well as the prognosis of CDH patients.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48666956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is an accessible, inexpensive, and harmless technique that can be used at bedside as frequently as required. Timely focused CUS in the neonatal care unit can play a major role in the diagnosis, follow-up, and management of brain damage. Despite the increasing use of point-of-care ultrasonography by intensive care physicians, neonatologist-performed CUS remains unusual. This review aims to provide an overview of neonatal CUS to neonatologists, focusing on the optimal settings, standard planes of the brain, and main pathologies in preterm infants. Adding Doppler studies allows evaluation of the patency of intracranial arteries and veins, flow velocities, and indices. This may provide an opportunity for earlier targeted circulatory support to prevent brain injury and improve long-term neurodevelopmental outcomes.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44482779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors implemented the Golden Hour protocol (GHP) that aims to close the final incubator within one hour of birth by implementing early treatment steps for premature infants after birth, such as maintaining body temperature, securing airway, and rapidly administering glucose fluid and prophylactic antibiotics by securing breathing and rapid blood vessels. This study investigated the effect of GHP application on the short- and long-term clinical outcomes.Methods: We retrospectively analyzed the medical records between 2017 and 2018 before GHP application and between 2019 and 2020 after GHP application in preterm infants aged 24 weeks or older and those aged less than 33 weeks who were admitted to the neonatal intensive care unit.Results: Overall, 117 GHP patients and 81 patients without GHP were compared and analyzed. Peripheral vascularization time and prophylactic antibiotic administration time were shortened in the GHP-treated group (P=0.007 and P=0.008). In the short-term results, the GHP-treated group showed reduced hypothermia upon arrival at the neonatal intensive care unit (P=0.002), and the blood glucose level at 1 hour of hospitalization was higher (P=0.012). Furthermore, the incidence of neonatal necrotizing enteritis decreased (P=0.043). As a long-term result, the incidence of BPD was reduced (P=0.004).Conclusion: We confirmed that applying GHP improved short- and long-term clinical outcomes in premature infants aged <33 weeks age of gestation, and we expect to improve the treatment quality by actively using it for postnatal treatment.","PeriodicalId":32945,"journal":{"name":"Neonatal Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47186172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there have been minimal efforts in the courses of resident training in Korea. The purpose of this study is to evaluate the change in knowledge and attitude before and after a 4-week breastfeeding educational intervention among multicenter residents.Methods: Prospective interventional educational research was designed for residents at eight training hospitals in Korea. Institutional reviews were obtained in each hospital. The education curriculum consisted of 14 courses regarding breastfeeding theory and practice. These materials were used to teach pediatric residents for 4 weeks. Knowledge-based tests were administered before the course, and re-tests were administered after the course using different test items of similar levels. Test scores and survey responses were compared before and after the intervention.Results: A total of 73 residents (1st year 20, 2nd year 23, 3rd year 16, and 4th year residents 14) from eight training hospitals completed the intervention. Their average age was 30.3±2.9 years, 17 (23.3%) were male, 22 (30.1%) were married, and eight had more than one child of their own. The mean pre-test score was 61.8±13.4 and the mean post-test score was 78.3±7.5 (P<0.001).
