Vegan/vegetarian diet and human milk donation: An EMBA survey across European milk banks.

The nutritional adequacy of human milk (HM) from vegan/vegetarian mothers has been a matter of debate, and a variety of recommendations regarding the eligibility of these mothers as human milk donors exists. According to the latest evidence, HM from vegans/vegetarians is similar in its composition to that from omnivores, however, some differences may be observed regarding vitamin B12 and omega-3 fatty acids concentrations. Maternal supplementation of these compounds has been proven effective in increasing their HM concentration. With this survey, we aimed to explore the practices currently in use in European human milk banks (HMBs) regarding potential donors following vegan/vegetarian diets. The online survey was distributed to European HMBs between January and July 2022. A total of 188 HMBs were contacted, and 118 replied (response rate 63%). Vegan and vegetarian mothers were recommended supplements of vitamin B12 to be accepted as donors in 27% and 26% of HMBs, respectively. Additional omega-3 fatty acid supplementation was required in 8% HMBs. In the remaining HMBs, these mothers were either systematically excluded or included regardless of supplementation. The dosage of the recommended supplements was extremely variable. Fifty-one percent of HMBs were following recommendations to guide their practice, national or local recommendations mainly. Great variability in European HMBs practices towards potential donors following vegan/vegetarian diets exists. Some of these practices can result in loss of donors and/or in potential nutritional deficiencies. Standardised evidence-based recommendations on this issue and their implementation in daily HMB practice are needed.

COVID-19 Disease in Presenting to the Pediatric Emergency Department: A Multicenter Study of 8886 Cases.

BACKGROUND: The aim was to evaluate the epidemiological, clinical, laboratory, and radiologic data of children with SARS-CoV-2 positivity by polymerase chain reaction (PCR) together with treatment strategies and clinical outcomes and to evaluate cases of multisystem inflammatory syndrome in children (MIS-C) in this population. METHODS: This was a multicenter retrospective observational cohort study performed in the pediatric emergency departments of 19 tertiary hospitals. From March 11, 2020, to May 31, 2021, children who were diagnosed with confirmed nasopharyngeal/tracheal specimen SARS-CoV-2 PCR positivity or positivity for serum-specific antibodies against SARS-CoV-2 were included. Demographics, presence of chronic illness, symptoms, history of contact with SARS-CoV-2 PCR-positive individuals, laboratory and radiologic investigations, clinical severity, hospital admissions, and prognosis were recorded. RESULTS: A total of 8886 cases were included. While 8799 (99.0%) cases resulted in a diagnosis of SARS-CoV-2 with PCR positivity, 87 (1.0%) patients were diagnosed with MIS-C. Among SARS-CoV-2 PCR-positive patients, 51.0% were male and 8.5% had chronic illnesses. The median age was 11.6 years (IQR: 5.0-15.4) and 737 (8.4%) patients were aged <1 year. Of the patients, 15.5% were asymptomatic. The most common symptoms were fever (48.5%) and cough (30.7%) for all age groups. There was a decrease in the rate of fever as age increased (p < 0.001); the most common age group for this symptom was <1 year with the rate of 69.6%. There was known contact with a SARS-CoV-2 PCR-positive individual in 67.3% of the cases, with household contacts in 71.3% of those cases. In terms of clinical severity, 83 (0.9%) patients were in the severe-critical group. There was hospital admission in 1269 (14.4%) cases, with 106 (1.2%) of those patients being admitted to the pediatric intensive care unit (PICU). Among patients with MIS-C, 60.9% were male and the median age was 6.4 years (IQR: 3.9-10.4). Twelve (13.7%) patients presented with shock. There was hospital admission in 89.7% of these cases, with 29.9% of the patients with MIS-C being admitted to the PICU. CONCLUSION: Most SARS-CoV-2 PCR-positive patients presented with a mild clinical course. Although rare, MIS-C emerges as a serious consequence with frequent PICU admission. Further understanding of the characteristics of COVID-19 disease could provide insights and guide the development of therapeutic strategies for target groups.

Antenatal Steroids and Acute Kidney Injury in Preterm Infants.

OBJECTIVE: The aim of this study was to identify the effects of antenatal steroids (ANS) on acute kidney injury (AKI) in very low birth weight (VLBW) preterm infants. STUDY DESIGN: We performed a retrospective cohort study of VLBW infants admitted to a tertiary-care neonatal intensive care unit between January 2016 and June 2019. Infants were divided into no ANS, partial ANS, and complete ANS groups. Serum creatinine (SCr) levels and rates of AKI during the first 2 weeks of life were compared. RESULTS: During the study period, 335 infants met our inclusion criteria. Among no, partial, and complete ANS groups, there were significant differences in rates of stages 2 and 3 AKI (17, 11, and 6%, respectively). Logistic regression analysis revealed that complete ANS course was associated with lower rates of AKI (odds ratio [OR] = 0.41 95% confidence interval [CI]: 0.20-0.83) and stages 2 and 3 AKI (OR = 0.205 95% CI: 0.075-0.563) compared with no ANS. Infants in complete ANS group had significantly lower SCr at 72 hours of life and at discharge, SCr peak was compared with infants in no ANS group. CONCLUSION: In VLBW infants, complete ANS exposure may be associated with improved renal function and decreased risk for AKI compared with no ANS. KEY POINTS: · The effects of antenatal steroid treatment on renal function in preterm infants are not clear.. · A complete course of antenatal steroid decreases the risk for acute kidney injury in preterm infants.. · Infants who are not exposed to antenatal steroids need closer observation of their renal function..

Oral Ibuprofen Versus Oral Paracetamol in Pain Management During Screening for Retinopathy of Prematurity: A Prospective Observational Study.

Screening examinations for retinopathy of prematurity (ROP) are critical to reduce ROP-related vision loss; however, the procedure is painful and uncomfortable, and topical anesthetics do not completely suppress the pain responses. The number of safe and effective pharmacological options to reduce pain during eye examinations for ROP screening in preterm infants is limited. This study compared the efficacy of oral ibuprofen and oral paracetamol in reducing pain during screening for ROP in preterm infants. This prospective observational study was conducted at a tertiary-care neonatal intensive care unit. Forty-four preterm infants with gestational age of 32 weeks and less undergoing ROP screening were included. Each enrolled infant received either oral ibuprofen 10 mg/kg (n = 22) or oral paracetamol 10 mg/kg (n = 22) 1 hour before eye examination. The primary outcome measure was pain assessed by the Neonatal Pain, Agitation, and Sedation Scale (N-PASS). Secondary outcome measures were tachycardia, bradycardia, desaturations, and crying time. The groups were similar for gestational age, birth weight, and postnatal age at examination (P > .05). The mean N-PASS scores were not significantly different between the oral ibuprofen and oral paracetamol groups (8.64 ± 1.57 vs 8.50 ± 1.71, respectively, P = .605). Moreover, no significant intergroup differences were observed in the crying time and the incidence of tachycardia/bradycardia and desaturation (P > .05). Ibuprofen or paracetamol administered orally before ROP screening in preterm infants had similar analgesic effects and did not significantly alleviate pain during eye examination.

Letter to the editor: clarifying some aspects and the terminology of individualized human milk fortification.

This letter has been written by the components of the European Milk Bank Association (EMBA) Working Group on Human Milk Fortification in response to a recent paper published by Mathes et al. (BMC Pediatr. 2018 May 8;18(1):154) with the aim of drawing attention to the importance of the use of a metabolic marker to adapt protein intake in preterm infants. EMBA Working Group on Human Milk Fortification clarifies further the terminology and some specific aspects regarding individualized human milk fortification. There are two types of individualized human milk fortification: Adjustable human milk fortification and Targeted human milk fortification. Advantages and disadvantages of these methods are summarized.

Nutritional adequacy of a novel human milk fortifier from donkey milk in feeding preterm infants: study protocol of a randomized controlled clinical trial.

BACKGROUND: Fortification of human milk is a standard practice for feeding very low birth weight infants. However, preterm infants often still experience suboptimal growth and feeding intolerance. New fortification strategies and different commercially available fortifiers have been developed. Commercially available fortifiers are constituted by a blend of ingredients from different sources, including plant oils and bovine milk proteins, thus presenting remarkable differences in the quality of macronutrients with respect to human milk. Based on the consideration that donkey milk has been suggested as a valid alternative for children allergic to cow's milk proteins, due to its biochemical similarity to human milk, we hypothesized that donkey milk could be a suitable ingredient for developing an innovative human milk fortifier. The aim of the study is to evaluate feeding tolerance, growth and clinical short and long-term outcomes in a population of preterm infants fed with a novel multi-component fortifier and a protein concentrate derived from donkey milk, in comparison to an analogous population fed with traditional fortifier and protein supplement containing bovine milk proteins. METHODS: The study has been designed as a randomized, controlled, single-blind clinical trial. Infants born <1500 g and <32 weeks of gestational age were randomized to receive for 21 days either a combination of control bovine milk-based multicomponent fortifier and protein supplement, or a combination of a novel multicomponent fortifier and protein supplement derived from donkey milk. The fortification protocol followed is the same for the two groups, and the two diets were designed to be isoproteic and isocaloric. Weight, length and head circumference are measured; feeding tolerance is assessed by a standardized protocol. The occurrence of sepsis, necrotizing enterocolitis and adverse effects are monitored. DISCUSSION: This is the first clinical study investigating the use of a human milk fortifier derived from donkey milk for the nutrition of preterm infants. If donkey milk derived products will be shown to improve the feeding tolerance or either of the clinical, metabolic, neurological or auxological outcomes of preterm infants, it would be an absolute innovation in the field of feeding practices for preterm infants.

A Case Study of Intractable Diarrhea Due to Neonatal Microvillous Inclusion Disease.

BACKGROUND: Microvillous inclusion disease (MVID) is one of the most severe congenital diarrhea disorders, caused by a genetic defect in enterocyte differentiation and polarization. CASE REPORT: We describe a neonate who presented with severe weight loss, hypernatremic dehydration and metabolic acidosis due to intractable diarrhea due to MVID, confirmed by electron microscopy. CONCLUSION: MVID can present with severe weight loss, hypernatremic dehydration and metabolic acidosis that is life threatening. The diagnosis is made by typical findings on light microscopy and electron microscope of small bowel biopsies. The only therapeutic options at this time are total parenteral nutrition and bowel rest and intestinal transplantation.

Massive pericardial effusion due to intrapericardial mixed germ cell tumor in a premature baby.

Primary cardiac tumor is uncommon in childhood, with an incidence of 0.06-0.32%, and intrapericardial teratoma represents an exceptional rarity among these entities. Germ cell tumors (GCT) are rare, representing only 1-3% of childhood tumors. Twenty per cent of GCT are malignant and are associated with age and location. Extragonadal involvement accounts for nearly half of the cases. Anterior mediastinum is a common location of malignant germ cell tumors, yet pericardial and aortic adventitia involvement have been rarely reported. Here we report the case of a preterm twin baby boy with intrapericardial mixed germ cell tumor who presented with hydrops fetalis and pericardial effusion.

Inactivation of high-risk human papillomaviruses by Holder pasteurization: implications for donor human milk banking.

AIMS: Several studies have recently reported the detection of oncogenic human papillomaviruses (HPV) in human milk of a minority of lactating mothers. These findings raised safety concerns in the context of human donor milk banking given the potential risk of HPV transmission to recipient infants. The aim of this study was to investigate whether the Holder pasteurization, a procedure currently in use in human donor milk banks for milk pasteurization, completely inactivates high-risk and low-risk HPV. METHODS: HPV pseudoviruses (PsV) were generated, spiked into cell culture medium or donor human milk and subjected to thermal inactivation. HPV PsV infectivity and morphological integrity was analyzed by cell-based assay and by electron microscopy, respectively. RESULTS: The Holder pasteurization completely inactivated the infectivity of high-risk (types 16 and 18) and low-risk (type 6) HPV both in cell culture medium and in human milk causing PsV particle disassembly. CONCLUSIONS: The results presented here indicate that the Holder pasteurization is an efficient procedure to inactivate high-risk and low-risk HPV thus preventing the potential risk of their transmission through human donor milk.

Impact of breast milk on cortical pain response in newborns during the heel prick procedure: a randomized controlled trial.

OBJECTIVE: To investigate the effects of breast milk on cortical pain response and behavioral response in newborns during heel-prick procedure. STUDY DESIGN: A prospective, randomized controlled trial was conducted on healty-term newborns, undergoing heel blood sampling. Infants were randomly assigned to study group with receive orally 2 ml breast milk (n = 45) or a control group with no intervention (n = 45). A near-infrared spectroscopy device was used to monitor regional cerebral oxygen saturation (rScO2), while neonatal pain expression was assessed by Neonatal Pain, Agitation, and Sedation Scale (N-PASS). RESULTS: The N-PASS score (p = 0.001) and the crying time (p = 0.017) were significantly lower in the study group compared to the control group. Although the mean rScO2 values decreased in both groups during the procedure, the percent change in rScO2 was not significant difference between two groups. CONCLUSION: Breast milk administration decreases behavioral responses to a noxious stimulus without reducing the cortical response to pain. CLINICAL TRIAL REGISTRATION: This trial was registered under ClinicalTrials.gov identifier no. NCT05961904.

Composition of Microbiota in Transient and Mature Human Milk: Significant Changes in Large for Gestational Age Group.

The composition of the human milk (HM) microbiota and, consequently, the microorganisms that are passed on to the infant through breastfeeding, can be influenced by various factors such as the mother's health and diet, gestational age, delivery mode, lactation stage, method of infant feeding, and geographical location. The aim of the Human Milk-Gest Study was to compare the microbiota of transient (postpartum 7-15 days) and mature HM (postpartum 45-90 days) of 44 mothers, and to investigate any potential changes associated with preterm birth, mode of delivery, and birth weight in relation to gestational age. The data were classified into five study groups: normal spontaneous delivery-term (NS-T) newborns, cesarean delivery-term (CS-T) newborns, preterm (PT) newborns (with a gestational age of less than 37 weeks), small for gestational age (SGA) newborns, and large for gestational age (LGA) newborns. An analysis of differential abundance was conducted using ANCOM-BC to compare the microbial genera between transient and mature HM samples as well as between other study groups. A significant difference was detected between HM samples at different sampling times and between the study groups (p < 0.01). In transient HM samples, Ralstonia, Burkholderiaceae_uc, and Pelomonas were significantly dominant in the LGA group compared to the NS-T, CS-T, PT, and SGA groups. In mature HM samples, Burkholderiaceae_uc, Ralstonia, Pelomonas, and Klebsiella were significantly dominant in the LGA group compared to the NS-T, CS-T, and PT groups, while Ralstonia, Burkholderiaceae_uc, and Pelomonas were significantly dominant in the LGA group compared to the SGA group. Differences were also detected between the transient and mature HM samples in the CS-T, PT, SGA, and LGA groups, but no differences occurred in the NS-T groups. In conclusion, we showed that Ralstonia, Burkholderiaceae_uc, and Pelomonas were significantly dominant in the LGA group in transient HM and continued in mature HM. The body mass index (BMI) of the mothers in the LGA group was not >30 at conception, however, the maternal BMI at birth and maternal weight gain during pregnancy were higher than in the other groups. The nutritional composition of HM is specifically designed to meet infant nutritional requirements during early life. Evaluating the effects of HM microbiota on infant microbiota composition and short- and long-term health effects in larger studies would be useful.

New alternatives to holder pasteurization in processing donor milk in human milk banks.

Infectious and toxicological risks are the main potential hazards that operators of Human Milk Banks (HMBs) encounter and must eliminate. HMBs are trying to implement procedures that allow to manage and sanitize human milk without altering significantly its nutritional and biologically protective components, obtaining a product characterized by a valid balance between safety and biological quality. The history of human milk processing is linked to the origins of HMBs themselves. And although other forms of sterilization were used originally, pasteurization soon became the recognized most effective means for sanitizing milk: all the milk that arrives at the HMB must be pasteurized. Holder pasteurization (HoP) is the most used methodology, and it is performed using low temperature and long time (+62.5°C for 30 min). With HoP some bioactive milk components are lost to varying degrees, but many other precious bioactive compounds are completely or partially preserved. To improve the quality of human milk processed by HMBs, maintaining in the meantime the same microbiological safety offered by HoP, new technologies are under evaluation. At present, High-Temperature Short-Time pasteurization (HTST) and High-Pressure Processing are the most studied methodologies. HTST is already utilized in some HMBs for daily practical activity and for research purposes. They seem to be superior to HoP for a better preservation of some nutritional and biologically protective components. Freeze-drying or lyophilization may have advantages for room temperature storage and transportation. The aim of this study is to evaluate the advancement regarding the processing of DHM with a literature search from 2019 to 2022. The effects of the new technologies on safety and quality of human milk are presented and discussed. The new technologies should assure microbiological safety of the final product at least at the same level as optimized HoP, with an improved preservation of the nutritional and bioactive components of raw human milk.

Effect of prolonged refrigeration on the lipid profile, lipase activity, and oxidative status of human milk.

OBJECTIVE: The study was aimed at evaluating the effect of prolonged refrigeration of fresh human milk (HM) on its fatty acid profile, free fatty acid content, lipase activities, and oxidative status. METHODS: HM from mothers of preterm newborns was collected, pooled, and placed in the neonatal intensive care unit (NICU) refrigerator. Pooled milk was aliquoted and analyzed within 3 hours of collection, and after 24, 48, 72, and 96 hours of storage. The milk samples were analyzed for pH, total and free fatty acid profile, lipase activity at room temperature and at 4°C, lipase activity at room temperature in presence of sodium cholate (bile salt-dependent lipase), total antioxidant capacity, thiobarbituric acid reactive species, malondialdehyde, and conjugated diene concentration. The experiment was replicated in 3 independent trials. RESULTS: Prolonged refrigeration did not affect the fatty acid composition of breast milk, and preserved both its overall oxidative status and the activity of HM lipolytic enzymes. In particular, bile salt-dependent lipase activity, long-chain polyunsaturated fatty acids, and medium-chain saturated fatty acid concentrations were unaffected for up to 96 hours of refrigerated storage. CONCLUSIONS: Prolonged refrigeration of fresh HM for 96 hours maintained its overall lipid composition. The limited lipolysis during storage should be ascribed to the activity of lipoprotein lipase, responsible for the decrease in pH. Our study demonstrates that infants who receive expressed milk stored for up to 96 hours receive essentially the same supply of fatty acids and active lipases as do infants fed directly at the breast.

Donor human milk for preterm infants: current evidence and research directions.

The Committee on Nutrition of the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition aims to document the existing evidence of the benefits and common concerns deriving from the use of donor human milk (DHM) in preterm infants. The comment also outlines gaps in knowledge and gives recommendations for practice and suggestions for future research directions. Protection against necrotizing enterocolitis is the major clinical benefit deriving from the use of DHM when compared with formula. Limited data also suggest unfortified DHM to be associated with improved feeding tolerance and with reduced cardiovascular risk factors during adolescence. Presence of a human milk bank (HMB) does not decrease breast-feeding rates at discharge, but decreases the use of formula during the first weeks of life. This commentary emphasizes that fresh own mother's milk (OMM) is the first choice in preterm infant feeding and strong efforts should be made to promote lactation. When OMM is not available, DHM is the recommended alternative. When neither OMM nor DHM is available, preterm formula should be used. DHM should be provided from an established HMB, which follows specific safety guidelines. Storage and processing of human milk reduces some biological components, which may diminish its health benefits. From a nutritional point of view, DHM, like HM, does not meet the requirements of preterm infants, necessitating a specific fortification regimen to optimize growth. Future research should focus on the improvement of milk processing in HMB, particularly of heat treatment; on the optimization of HM fortification; and on further evaluation of the potential clinical benefits of processed and fortified DHM.

Presence of human milk bank is associated with elevated rate of exclusive breastfeeding in VLBW infants.

Human milk confers health benefits of vital importance for the sick and preterm infants in neonatal intensive care units (NICUs). Mother's own milk is the first choice in preterm infant feeding, and every effort should be made to promote lactation. When mother's milk is not available or is insufficient, donor human milk (DHM) is recommended. Yet, occasionally, the concern that the use of DHM might decrease breastfeeding is being raised. The present data collection planned by the Italian Association of Human Milk Banks (AIBLUD) in collaboration with the Italian Neonatal Network (INN) attempted to address this concern. A total of 4277 very low birth weight (VLBW) infants from 83 Italian NICUs were evaluated for this comparative analysis. The 83 Italian NICUs were divided into two groups: centers with a human milk bank (HMB) and centers without a HMB; the available parameters in the network--"any and exclusive breastfeeding rates" and "exclusive formula rate" at discharge--were compared. Exclusive breastfeeding rate at discharge was significantly higher in NICUs with a HMB than in NICUs without (29.6% vs. 16.0%, respectively). Any breastfeeding rate at discharge tended to be higher in the NICUs with HMB (60.4% vs. 52.8%, P = 0.09), and exclusive formula rate was lower in the NICUs with HMB (26.5% vs. 31.3%), but this difference was not significant. This report shows that the presence of a HMB and the use of DHM in NICU are associated with increased breastfeeding rate at discharge from the hospital for VLBW infants.

Recommendations for the establishment and operation of a donor human milk bank.

In Europe, an increasing number of human milk banks (HMBs) collect donor human milk to feed preterm infants when their mother's milk is not available or not enough. Moreover, donor milk is a bridge to breastfeeding, with positive clinical and psychological advantages for both mother and infant. Italy, with 41 HMBs actively operating in 2022, has the highest number of HMBs in Europe. The process of human milk donation is complex, so activity of HMBs must be regulated according to well-established rules. The present recommendations have been prepared as a tool to standardize the organization, management, and procedures of HMBs operating in Italy and to determine the minimal essential requirements to establish new HMBs. This article covers all the aspects of human milk donation and human milk banking, including general recommendations, donor recruitment and screening, expression, handling and storage of donor human milk, milk screening, and milk treatment (pasteurization). A pragmatic approach was taken to drafting the recommendations. Items for which there was consensus or robust published evidence on which to base recommendations were included. When there were differences that could not be resolved by reference to published research, a statement of explanation based on the expert opinion of the authors (all members of the Italian Association of Human Milk Banks) was included. Implementation of these recommendations can contribute to promotion of breastfeeding.

Antibiotic use in infants in the first year of life in five European countries.

AIM: To assess in infants the number of illness episodes treated with antibiotics and prescription rates in five European countries. METHODS: This study was embedded in a multicenter nutritional intervention study and was conducted in five European countries. Infants were followed until 1 year of age. Illness episodes and prescriptions of systemic antibiotics were recorded by the parents. RESULTS: Illness episodes were caused by upper respiratory tract infections (URTIs) in 55-64% and by otitis media (OM) in 2-6.8%. URTIs were statistically significant and more frequently treated with antibiotics in Italy (18.8%), and less frequently in Switzerland (1.4%). OM was statistically significant and less frequently treated with antibiotics in the Netherlands (55%) when compared to Italy (82%). The antibiotic prescription rate varied between countries, ranging from 0.2 to 1.3 prescriptions per infant per year. CONCLUSIONS: As the frequency of illness episodes did not differ between countries, other factors, such as physician's attitude, parental pressure or other socio-economic determinants, most likely play a role in antibiotic prescribing habits in the first year of life.

WAPM Working Group on Nutrition: potential chronobiotic role of human milk in sleep regulation.

BACKGROUND: Organization of the sleep states and a normal sleep pattern in the neonatal period and early infancy is essential for brain development and plasticity. The establishment of a consolidated circadian sleep-wake cycle occurs between 1 and 4 months of life in term infants. This period may be even longer for preterm infants who are exposed to relentless interventions in neonatal intensive care units. The sleep should be respected and protected. OBJECTIVE AND METHODS: Human milk (HM) contains bioactive sleep-promoting components, and recent evidence shows that some of these components show circadian oscillations. This article reviews the existing evidence regarding the role of these HM components on sleep. This topic is prefaced with a brief information about the basic concepts concerning sleep. Consecutively, chronobiotic and chrononutrition concepts are introduced. RESULTS: Melatonin, tryptophan, nucleosides/nucleotides, and vitamin B12 are components of HM that have sleep-promoting characteristics. The sleep-inducing effects of these components are well-established in animal and adult human studies. Interestingly, melatonin, tryptophan, and 5'-adenosine monophosphate and 5'-guanosine monophosphate nucleotides in HM have been shown to exhibit also circadian oscillations. Although 5'-uridine monophosphate does not have a circadian rhythm, its levels increase during the night. CONCLUSION: HM has a potential to function as a "synchronizer," helping the infant to consolidate a circadian sleep-wake cycle, thanks to its several bioactive components with chronobiotic characteristics. Research is warranted to address gaps in this field, such as the association between the circadian oscillations of the sleep-promoting factors in HM and the quantity/quality of infant sleep.

Does antenatal corticosteroid therapy improve neonatal outcomes in late preterm birth?

BACKGROUND: Infants who are born at 34°/7 to 366/7 weeks of gestation (late preterm) are at greater risk for respiratory and other neonatal morbidities. The objective of this study was to examine the effects of the administration of antenatal corticosteroids (ACS) to women at risk for late preterm delivery on the incidence of neonatal outcomes. METHOD: This was a prospective cohort study of singleton gestations at risk of imminent delivery between 34°/7 and 366/7 weeks. Neonatal outcomes were compared between mothers who received ACS and those who did not. The primary outcome was the rate of composite respiratory morbidity defined as the need for treatment within 72 h of life (continuous positive airway pressure or high flow nasal cannula for least 2 h or supplemental oxygen with a fraction of inspired oxygen of at least 0.30 for at least four continuous hours or mechanical ventilation). RESULTS: During the 3-year study period, 595 subjects were included in this study, comprising 234 subjects that received ACS and 361 that did not. Administration of ACS significantly reduced the rates of composite respiratory morbidity (aOR 0.63 95% CI 0.40-0.99), the use of CPAP or HFNC for at least 2 h (aOR 0.57 95% CI 0.35-0.94), and transient tachypnea of the newborn (aOR 0.48 95% CI 0.28-0.82). Neonatal hypoglycemia was more significantly increased in the ACS group compared with controls (aOR 1.64 95% CI 1.04-2.59). We found no significant between-group differences in the rate of respiratory distress syndrome, surfactant use, need for resuscitation, jaundice requiring phototherapy, admission to neonatal intensive care or special care nursery, and duration of hospitalization. CONCLUSION: Administration of ACS during the late preterm period decreased neonatal respiratory complications, however, increased the rate of hypoglycemia.

Does antenatal corticosteroid therapy improve neonatal outcomes in late preterm birth?

BACKGROUND: Infants who are born at 340/7 to 366/7 weeks of gestation (late preterm) are at greater risk for respiratory and other neonatal morbidities. The objective of this study was to examine the effects of administration of antenatal corticosteroids (ACSs) to women at risk for late preterm delivery on the incidence of neonatal outcomes. METHODS: This was a prospective cohort study of singleton gestations at risk of imminent delivery between 340/7 and 366/7 weeks. Neonatal outcomes were compared between mothers who received ACS and those who did not. Primary outcome was the rate of composite respiratory morbidity defined as the need for treatment within 72 h of life (continuous positive airway pressure or high flow nasal cannula for least 2 h or supplemental oxygen with a fraction of inspired oxygen of at least 0.30 for at least four continuous hours or mechanical ventilation). RESULTS: During the 3-year study period, 595 subjects were included in this study, comprising 234 subjects that received ACS and 361 that did not. Administration of ACS significantly reduced the rates of composite respiratory morbidity (adjusted odds ratio (aOR) 0.63, 95% confidence interval (CI) 0.40-0.99), the use of CPAP or HFNC for at least 2 h (aOR 0.57, 95% CI 0.35-0.94) and transient tachypnea of newborn (aOR 0.48, 95% CI 0.28-0.82). Neonatal hypoglycemia was more significantly increased in the ACS group compared with controls (aOR 1.64, 95% CI 1.04-2.59). We found no significant between-group differences in the rate of respiratory distress syndrome, surfactant use, need for resuscitation, jaundice requiring phototherapy, admission to neonatal intensive care or special care nursery and duration of hospitalization. CONCLUSION: Administration of ACS during the late preterm period decreased neonatal respiratory complications, however, increased the rate of hypoglycemia.
