Probiotics Prevent Late-Onset Sepsis in Human Milk-Fed, Very Low Birth Weight Preterm Infants: Systematic Review and Meta-Analysis
Growing evidence supports the role of probiotics in reducing the risk of necrotizing enterocolitis, time to achieve full enteral feeding, and late-onset sepsis (LOS) in preterm infants. As reported for several neonatal clinical outcomes, recent data have suggested that nutrition might affect probiotics\u2019 efficacy. Nevertheless, the currently available literature does not explore the relationship between LOS prevention and type of feeding in preterm infants receiving probiotics. Thus, the aim of this systematic review and meta-analysis was to evaluate the effect of probiotics for LOS prevention in preterm infants according to type of feeding (exclusive human milk (HM) vs. exclusive formula or mixed feeding). Randomized-controlled trials involving preterm infants receiving probiotics and reporting on LOS were included in the systematic review. Only trials reporting on outcome according to feeding type were included in the meta-analysis. Fixed-effects models were used and random-effects models were used when significant heterogeneity was found. The results were expressed as risk ratio (RR) with 95% confidence interval (CI). Twenty-five studies were included in the meta-analysis. Overall, probiotic supplementation resulted in a significantly lower incidence of LOS (RR 0.79 (95% CI 0.71\u20130.88), p < 0.0001). According to feeding type, the beneficial effect of probiotics was confirmed only in exclusively HM-fed preterm infants (RR 0.75 (95% CI 0.65\u20130.86), p < 0.0001). Among HM-fed infants, only probiotic mixtures, and not single-strain products, were effective in reducing LOS incidence (RR 0.68 (95% CI 0.57\u20130.80) p < 0.00001). The results of the present meta-analysis show that probiotics reduce LOS incidence in exclusively HM-fed preterm infants. Further efforts are required to clarify the relationship between probiotics supplementation, HM, and feeding practices in preterm infants
Complementary Feeding in the Preterm Infants: Summary of Available Macronutrient Intakes and Requirements
Limited data are available regarding the nutritional needs for preterm infants. In most cases, guidelines refer to the acquisition of neuromotor skills, adequate weight and corrected chronological age. While waiting for the establishment of specific nutritional indications for premature infants we proposed the weaning recommendations for term infants of the Italian Society of Human Nutrition with LARNs (Reference intake Levels of Nutrients and energy for the Italian population) of 2014, the Dietary Reference Values for nutrients of European Food Safety Authority (EFSA) of 2017 and the Nutrient Reference Values for Australia and New Zealand Including Recommended Dietary Intakes of 2017
Weaning Time in Preterm Infants: An Audit of Italian Primary Care Paediatricians
Introduction: According to the 2016 Italian National Institute of Statistics (Istat) data in Italy, about 6.7% of all newborns are born prematurely. Due to the lack of data on current complementary feeding in preterm infants in Italy, the aim of the survey was to evaluate individual attitudes of primary care paediatricians, concerning the introduction of complementary foods in preterm infants. Methods: An internet-based survey was conducted among primary care paediatricians, working in Italy, regarding (1) timing of the introduction of complementary foods to preterm newborns; (2) type of complementary foods introduced; (3) vitamin D and iron supplementations. Results: A total of 347 primary care Italian paediatricians answered the questionnaire; 44% of responders based the timing of the introduction of solid food exclusively on an infant’s age, 18% on an infant’s neurodevelopmental status and 4% on the body weight; the remaining 34% based the timing on two or more of these aspects. The type of complementary foods did not comply with an evidence-based sequence; 98% of participants promoted vitamin D supplementation and 89% promoted iron supplementation with great diversity in timing and doses. Conclusions: Due to limited evidence, there is a great heterogeneity in the attitudes of primary care paediatricians concerning the introduction of complementary foods to preterm newborns. Further research is needed to provide evidence-based guidelines regarding weaning preterm newborns
Netilmicin effect on urinary Retinol Binding Protein (RBP) and N-Acetyl-Beta-D-Glucosaminidase (NAG) in preterm newborns with and without anoxia
The study aim was to evaluate urinary excretion of Retinol Binding Protein (RBP), compared with urinary excretion of N-acetyl-beta-D-glucosaminidase (NAG), in preterm infants with anoxia and netilmicin treatment. Urinary RBP and NAG were evaluated in 83 preterm newborns divided in 4 groups: 37 healthy preterm newborns (controls); 14 with neonatal anoxia; 16 treated with ampicillin + netilmicin; 16 with neonatal anoxia and treated with ampicillin + netilmicin. RBP was determined by an automated nephelometric technique and NAG by a colorimetric method on 5-h urine samples in the first week of life. Results showed that urinary excretion of RBP (average from first week values) was 1.06+/-0.67 g/mol creatinine (mean +/- SD) in controls, 1.99+/-1.41 in antibiotic-treated newborns, 3.99+/-4.57 in anoxic newborns and 3.75+/-3.48 in anoxic newborns under antibiotic treatment. When gestational age was not considered, a marked effect of anoxia (P<0.001) and a borderline effect of netilmicin (P<0.059) on RBP excretion were detected by ANOVA. However when gestational age was also considered by analysis of covariance, it appeared as the strongest predictor of RBP excretion (P<0.001), while the effect of netilmicin was no longer significant (P=0.181). The effect of anoxia persisted, although less remarkable (P=0.010). Conversely anoxia did not affect urinary NAG excretion, which was rather correlated with gestational age and netilmicin administration. The authors conclude that RBP and NAG urinary excretion may be used to discriminate between neonatal anoxia and netilmicin treatment, respectively as etiologic factors of renal tubular damage in the newborn
The Italian screening program for primary congenital hypothyroidism: actions to improve screening, diagnosis, follow-up, and surveillance.
Strategies for preventing group B streptococcal infections in newborns: a nation-wide survey of Italian policies
Abstract Background There are no Italian data regarding the strategies for preventing neonatal group B streptococcal (GBS) infection. We conducted a national survey in order to explore obstetrical, neonatal and microbiological practices for the GBS prevention. Methods Three distinct questionnaires were sent to obstetricians, neonatologists and microbiologists. Questionnaires included data on prenatal GBS screening, maternal risk factors, intrapartum antibiotic prophylaxis, microbiological information concerning specimen processing and GBS antimicrobial susceptibility. Results All respondent obstetrical units used the culture-based screening approach to identify women who should receive intrapartum antibiotic prophylaxis, and more than half of the microbiological laboratories (58%) reported using specimen processing consistent with CDC guidelines. Most neonatal units (89 out of 107, 82%) reported using protocols for preventing GBS early-onset sepsis consistent with CDC guidelines. Conclusions The screening-based strategy is largely prevalent in Italy, and most protocols for preventing GBS early-onset sepsis are consistent with CDC guidelines. However, we found discrepancies in practices among centers that may reflect the lack of Italian guidelines issued by public health organizations
Nationwide survey of neonatal transportation practices in Italy
Abstract Background Despite regionalization of perinatal care provides for the “in utero” transfer of high-risk pregnancies, there will always be a number of neonates who undergo acute inter-facility transport. The presence of a well-organized Neonatal Emergency Transport Service (NETS) can prevent and reduce risks of transportation, especially for very preterm infants, and is therefore mandatory for any program of regionalization of perinatal care. Italian National Health System is highly decentralized and Regions are autonomous to structure, plan and delivery their regional health services. Consequently, organization models and resources available vary widely and significant regional differences in access and quality of health services have been reported in the past years. A national survey was conducted in 2015 by the neonatal transport study group of the Italian Society of Neonatology with the aim to describe neonatal transfer practices and to assess the Neonatal Emergency Transport Services (NETS) status in the 20 Italian regions. Methods A questionnaire regarding neonatal transfer practices and NETS activity for the previous year (2014) was sent to the 44 NETS operating in the 20 Italian regions. Demographic data were obtained from the Italian National Statistical Institute (ISTAT). Results The overall survey response rate was 100%. In 2014, only 12 (60%) of the 20 Italian regions were fully covered by NETS, 3 (15%) regions were partially covered, while neonatal transport was not available in 5 (25%) regions. Overall, in 2014, the 44 NETS operating in Italy transported a total of 6387 infants, including 522 (8.17%) having a gestational age < 28 weeks. Conclusions The organization of NETS in Italy is devolved on a regional basis, resulting in a large heterogeneity of access and quality to services across the country. Where available, NETS are generally well-equipped and organized but limited volume of activities often cannot guarantee adequate levels of skills of personnel or an appropriate cost-efficiency ratio. The regions reported with lack of NETS have managed, or are trying, to fill the gap, but continuing efforts to reduce regional differences in the availability and quality of services are still needed
Neonatal respiratory support strategies for the management of extremely low gestational age infants: an Italian survey
Abstract Background We aimed to survey Delivery Room and Neonatal Intensive Care Unit (NICU) respiratory strategies dedicated to the extremely low gestational age newborn (ELGAN – GA < 28 wks) in Italy. Methods A questionnaire was sent to 113 Italian level III centres. A lead physician and a nurse with expertise in mechanical ventilation (MV) were identified in each unit to answer. Information about those aspects of ventilatory support considered by center’s staff as needing improvement was also collected. Results A 100% response rate was obtained. In the Delivery Room, sustained lung inflation was performed in 74.8% of centres, and 89.2% used NCPAP. For ELGANs who need invasive MV, conventional MV was the most used strategy. Volume-targeted ventilation and High-frequency oscillatory ventilation (HFOV) were considered as primary mode in < 30% of centres. Among non-invasive strategies, NCPAP was the most utilized, followed by BiPAP, High-flow nasal cannula and nasal intermittent positive pressure ventilation. Nurses more commonly recorded in the nursing charts the ventilator’s setting parameters rather than measured ones. HFOV and non-invasive ventilation were the most quoted aspects of neonatal ventilation felt as to be improved. Conclusion The routine respiratory support practices in Italy showed marked variations among units. Focused interventions are largely required to improve clinical practice
Novel Coronavirus disease (COVID-19) in newborns and infants: what we know so far
Recently, an outbreak of viral pneumonitis in Wuhan, Hubei, China successively spread as a global pandemia, led to the identification of a novel betacoronavirus species, the 2019 novel coronavirus, successively designated 2019-nCoV then SARS-CoV-2). The SARS-CoV-2 causes a clinical syndrome designated coronavirus disease 2019 (COVID19) with a spectrum of manifestations ranging from mild upper respiratory tract infection to severe pneumonitis, acute respiratory distress syndrome (ARDS) and death. Few cases have been observed in children and adolescents who seem to have a more favorable clinical course than other age groups, and even fewer in newborn babies. This review provides an overview of the knowledge on SARS-CoV-2 epidemiology, transmission, the associated clinical presentation and outcomes in newborns and infants up to 6 months of life
