RESUMO
PURPOSE: Few guidelines exist for the perioperative management (PM) of neonates with surgical conditions (SC). This study examined the current neonatal PM in Italy. METHODS: We invited 51 neonatal intensive care units with pediatric surgery in their institution to participate in a web-based survey. The themes included (1) the involvement of the neonatologist during the PM; (2) the spread of bedside surgery (BS); (3) the critical issues concerning the neonatal PM in operating rooms (OR) and the actions aimed at improving the PM. RESULTS: Response rate was 82.4%. The neonatologist is involved during the intraoperative management in 42.9% of the responding centers (RC) and only when the surgery is performed at the patient's bedside in 50.0% of RCs. BS is reserved for extremely preterm (62.5%) or clinically unstable (57.5%) infants, and the main barrier to its implementation is the surgical-anesthesiology team's preference to perform surgery in a standard OR (77.5%). Care protocols for specific SC are available only in 42.9% of RCs. CONCLUSION: Some critical issues emerged from this survey: the neonatologist involvement in PM, the spread of BS, and the availability of specific care protocols need to be implemented to optimize the care of this fragile category of patients.

Pneumothorax in newborns can be life-threatening. The traditional treatment of pneumothorax is chest drain placement. Recently, modified pigtail catheter has been proposed as a less traumatic approach despite limited experience in infants. To compare the effectiveness and safety of pigtail catheters versus traditional straight chest drains in term and preterm infants with pneumothorax, in two tertiary neonatal units: Policlinico Hospital in Bari, IT and John Radcliffe Hospital in Oxford, UK. We retrospectively reviewed medical records of 47 newborns with pneumothorax admitted to the two units between October 2009 and June 2017, and treated with either pigtail catheters or straight chest drains. Three newborns (6.7%) were excluded from the study because they were treated with both types of drains. The remaining 44 neonates were included in the analysis. Overall, 56.8% (n = 25/44) of pneumothoraces were drained with pigtail catheters and 43.2% (n = 19/44) with straight drains. No differences in gestational age and birth weight were found. The success rate, defined as complete radiological resolution of the pneumothorax after drainage, was significantly higher in the pigtail group (96.0% versus 73.7%; p < 0.05). Days of drainage, length of hospital stay and duration of respiratory support were not significantly different. Subcutaneous emphysema and drain dislodgement/malfunction occurred only in the straight drain group (0.0% versus 11.1%; p = 0.181). No significant differences in mortality between the two groups were found (28.0% pigtail group versus 26.3% straight drain group; p > 0.05).Conclusion: Pigtail catheters are a safe and effective alternative to traditional chest drains for infants with pneumothorax. What is Known:⢠Air leaks in newborns can represent an emergency, especially among preterms;⢠The first treatment in a life-threatening pneumothorax is thoracentesis with needle aspiration or placement of a chest drain.What is New:⢠Pigtail catheter have been described as an alternative to traditional chest drains;⢠Pigtail catheters are a safe and effective alternative to traditional chest drains for infants with pneumothorax.

OBJECTIVE: This study was aimed to evaluate effectiveness of lung ultrasound (LUS) in the management of congenital pulmonary airway malformation and pulmonary sequestration in NICUs. STUDY DESIGN: This is a nonconsecutive case series of neonates admitted to the academic NICU of Policlinico of Bari, Italy, from 2010 to 2018, for suspected lung malformations and examined by LUS. RESULTS: Seven neonates were admitted for suspected pulmonary malformations, four neonates were diagnosed with pulmonary sequestration and three with congenital pulmonary airway malformation either type I (two cases) or type II (one case) according to Adzick classification. Prenatal scans had described lung malformations in six patients. Two underwent surgical intervention during the 1st month of life. All were successfully discharged home and their follow-up has been uneventful thereafter. In all the seven neonates, LUS easily detected the lesion showing a significantly high correspondence with computed tomography (CT) scan findings. CONCLUSION: We described the first case series of neonates affected by complex pulmonary malformations, assessed by LUS. In our experience, LUS was safe and effective for the diagnosis with high degree of consistency with CT scan findings. We suggest that LUS might be an important diagnostic method for lung malformations in newborns and a useful technique for their follow-up and late management, avoiding multiple exposures to radiations.

BACKGROUND: Lactoferrin is the major antimicrobial protein in human milk. In our randomized controlled trial (RCT) of bovine lactoferrin (BLF) supplementation in preterm neonates, BLF reduced late-onset sepsis (LOS). Mother's own milk (MM) contains higher concentrations of lactoferrin than donor milk or formula, but whether BLF is more effective in infants who receive formula or donor milk is uncertain. AIM: To evaluate the incidence of LOS in preterm infants fed MM and in those fed formula and/or donor milk. STUDY DESIGN: This is a (A) post hoc subgroup analysis, in our RCT of BLF, of its effects in preterm infants fed MM, with or without formula, versus those fed formula and/or donor milk (no-MM) and (B) post hoc meta-analysis, in our RCT of BLF and in the ELFIN (Enteral Lactoferrin in Neonates) RCT, of the effect of BLF in subgroups not exclusively fed MM. RESULTS: (A) Of 472 infants in our RCT, 168 were randomized to placebo and 304 were randomized to BLF. Among MM infants, LOS occurred in 22/133 (16.5%) infants randomized to placebo and in 14/250 (5.6%) randomized to BLF (relative risk or risk ratio (RR): 0.34; relative risk reduction (RRR): 0.66; 95% confidence interval (95% CI) for RR: 0.18-0.64; p < 0.0008). Among no-MM infants, LOS occurred in 7/35 (20.0%) randomized to placebo and in 2/54 (3.7%) randomized to BLF (RR: 0.19; RRR: 0.81; 95% CI for RR: 0.16-0.96; p = 0.026). In multivariable logistic regression analysis, there was no interaction between BLF treatment effect and type of feeding (p = 0.628). (B) In 1,891 infants not exclusively fed MM in our RCT of BLF and in the ELFIN RCT, BLF reduced the RR of LOS by 18% (RR: 0.82; 95% CI: 0.71-0.96; p = 0.01). CONCLUSION: Adequately powered studies should address the hypothesis that BLF is more effective in infants fed formula or donor milk than those fed MM. Such studies should evaluate whether a specific threshold of total lactoferrin intake can be identified to protect such patients from LOS.

OBJECTIVE: To investigate whether exposure to inhibitors of gastric acidity, such as H2 blockers or proton pump inhibitors, can independently increase the risk of infections in very low birth weight (VLBW) preterm infants in the neonatal intensive care unit. STUDY DESIGN: This is a secondary analysis of prospectively collected data from a multicenter, randomized controlled trial of bovine lactoferrin (BLF) supplementation (with or without the probiotic Lactobacillus rhamnosus GG) vs placebo in prevention of late-onset sepsis (LOS) and necrotizing enterocolitis (NEC) in preterm infants. Inhibitors of gastric acidity were used at the recommended dosages/schedules based on the clinical judgment of attending physicians. The distribution of days of inhibitors of gastric acidity exposure between infants with and without LOS/NEC was assessed. The mutually adjusted effects of birth weight, gestational age, duration of inhibitors of gastric acidity treatment, and exposure to BLF were controlled through multivariable logistic regression. Interaction between inhibitors of gastric acidity and BLF was tested; the effects of any day of inhibitors of gastric acidity exposure were then computed for BLF-treated vs -untreated infants. RESULTS: Two hundred thirty-five of 743 infants underwent treatment with inhibitors of gastric acidity, and 86 LOS episodes occurred. After multivariate analysis, exposure to inhibitors of gastric acidity remained significantly and independently associated with LOS (OR, 1.03; 95% CI, 1.008-1.067; P = .01); each day of inhibitors of gastric acidity exposure conferred an additional 3.7% odds of developing LOS. Risk was significant for Gram-negative (P < .001) and fungal (P = .001) pathogens, but not for Gram-positive pathogens (P = .97). On the test for interaction, 1 additional day of exposure to inhibitors of gastric acidity conferred an additional 7.7% risk for LOS (P = .003) in BLF-untreated infants, compared with 1.2% (P = .58) in BLF-treated infants. CONCLUSION: Exposure to inhibitors of gastric acidity is significantly associated with the occurrence of LOS in preterm VLBW infants. Concomitant administration of BLF counteracts this selective disadvantage. TRIAL REGISTRATION: isrctn.org: ISRCTN53107700.

Preterm infants are at risk of hypoxia and hyperoxia because of the immaturity of their respiratory and antioxidant systems, linked to increased morbidity and mortality. This study aimed to evaluate the efficacy of a single administration of the SLAB51 probiotic formula in improving oxygenation in respiratory distress syndrome (RDS)-affected premature babies, thus reducing their need for oxygen administration. Additionally, the capability of SLAB51 in activating the factor-erythroid 2-related factor (Nrf2) responsible for antioxidant responses was evaluated in vitro. In two groups of oxygen-treated preterm infants with similar SaO2 values, SLAB51 or a placebo was given. After two hours, the SLAB51-treated group showed a significant increase in SaO2 levels and the SaO2/FiO2 ratio, while the control group showed no changes. Significantly increased Nrf2 activation was observed in intestinal epithelial cells (IECs) exposed to SLAB51 lysates. In preterm infants, we confirmed the previously observed SLAB51's "oxygen-sparing effect", permitting an improvement in SaO2 levels. We also provided evidence of SLAB51's potential to enhance antioxidant responses, thus counteracting the detrimental effects of hyperoxia. Although further studies are needed to support our data, SLAB51 represents a promising approach to managing preterm infants requiring oxygen supplementation.

CONTEXT: Sepsis is a common and severe complication in premature neonates, particularly those with very low birth weight (VLBW) (<1500 g). Whether lactoferrin, a mammalian milk glycoprotein involved in innate immune host defenses, can reduce the incidence of sepsis is unknown. In animal models, the probiotic Lactobacillus rhamnosus GG (LGG) enhances the activity of lactoferrin but has not been studied in human infants. OBJECTIVE: To establish whether bovine lactoferrin (BLF), alone or in combination with LGG, reduces the incidence of late-onset sepsis in VLBW neonates. DESIGN, SETTING, AND PATIENTS: Prospective, multicenter, double-blind, placebo-controlled, randomized trial conducted in 11 Italian tertiary neonatal intensive care units. Patients were 472 VLBW infants enrolled from October 1, 2007, through July 31, 2008, and assessed until discharge for development of sepsis. INTERVENTION: Infants were randomly assigned to receive orally administered BLF (100 mg/d) alone (n = 153), BLF plus LGG (6 x 10(9) colony-forming units/d) (n = 151), or placebo (n = 168) from birth until day 30 of life (day 45 for neonates <1000 g at birth). MAIN OUTCOME MEASURE: First episode of late-onset sepsis, ie, sepsis occurring more than 72 hours after birth with isolation of any pathogen from blood or from peritoneal or cerebrospinal fluid. RESULTS: Demographic, clinical, and management characteristics of the 3 groups were similar, including type of feeding and intake of maternal milk. Incidence of late-onset sepsis was significantly lower in the BLF and BLF plus LGG groups (9/153 [5.9%] and 7/151 [4.6%], respectively) than in the control group receiving placebo (29/168 [17.3%]) (risk ratio, 0.34; 95% confidence interval, 0.17-0.70; P = .002 for BLF vs control and risk ratio, 0.27; 95% confidence interval, 0.12-0.60; P < .001 for BLF plus LGG vs control). The decrease occurred for both bacterial and fungal sepsis. No adverse effects or intolerances to treatment occurred. CONCLUSION: Compared with placebo, BLF supplementation alone or in combination with LGG reduced the incidence of a first episode of late-onset sepsis in VLBW neonates.

INTRODUCTION: Viral bronchiolitis is a common cause of lower respiratory tract infection in the first year of life, considered a health burden because of its morbidity and costs. Its diagnosis is based on history and physical examination and the role of radiographic examination is limited to atypical cases. Thus far, Lung Ultrasound (LUS) is not considered in the diagnostic algorithm for bronchiolitis. METHODS: PubMed database was searched for trials reporting on lung ultrasound examination and involving infants with a diagnosis of bronchiolitis. RESULTS: Eight studies were suitable. CONCLUSIONS: This review analyzed the current evidence about the potential usefulness of LUS in the clinical management of bronchiolitis. Literature supports a peculiar role of LUS in the evaluation of the affected children, considering it as a reliable imaging test that could benefit the clinical management of bronchiolitis.
RESUMO
BACKGROUND: Strategies for prevention of HIV-1 mother-to-child transmission (PMTCT) have been continuously optimized. However, cases of vertical transmission continue to occur in high-income countries. OBJECTIVES: To investigate changes in PMTCT strategies adopted by Italian clinicians over time and to evaluate risk factors for transmission. METHODS: Data from mother-child pairs prospectively collected by the Italian Register, born in Italy in 1996-2016, were analyzed. Risk factors for MTCT were explored by logistic regression analyses. RESULTS: Six thousand five hundred three children (348 infections) were included. In our cohort, the proportion of children born to foreign mothers increased from 18.3% (563/3078) in 1996%-2003% to 66.2% (559/857) in 2011-2016 (P < 0.0001). Combination neonatal prophylaxis use significantly (P < 0.0001) increased over time, reaching 6.3% (56/857) after 2010, and it was largely (4.2%) adopted in early preterm infants. The proportion of vaginal deliveries in women with undetectable viral load (VL) increased over time and was 9.9% (85/857) in 2011-2016; no infection occurred among them. In children followed up since birth MTCT, rate was 3.5% (96/2783) in 1996-2003; 1.4% (36/2480) in 2004-2010; and 1.1% (9/835) in 2011-2016. At a multivariate analysis, factors associated with MTCT were vaginal delivery with detectable or missing VL or nonelective caesarean delivery, prematurity, breastfeeding, lack of maternal or neonatal antiretroviral therapy, detectable maternal VL, and age at first observation. Previously described increased risk of offspring of immigrant women was not confirmed. CONCLUSIONS: Risk of MTCT in Italy is ongoing, even in recent years, underling the need for implementation of the current screening program in pregnancy. Large combination neonatal prophylaxis use in preterm infants was observed, even if data on safety and efficacy in prematures are poor.

IMPORTANCE: NEC is a common and severe complication in premature neonates, particularly those with very-low-birth-weight (VLBW, <1500 g at birth). Probiotics including lactobacillus rhamnosus GG (LGG) proved effective in preventing NEC in preterm infants in several RCTs. OBJECTIVE: Lactoferrin, a mammalian milk glycoprotein involved in innate immune host defences, can reduce the incidence of NEC in animal models, and its action is enhanced by LGG. We tried to assess whether bovine lactoferrin (BLF), alone or with the probiotic LGG, has a similar effect in human infants, something that has not yet been studied. DESIGN: An international, multicenter, randomized, double-blind, placebo-controlled trial conducted from October 1st, 2007 through July 31st, 2010. SETTING: Thirteen Italian and New Zealand tertiary neonatal intensive care units. PARTICIPANTS: 743 VLBW neonates were assessed until discharge for development of NEC. INTERVENTION: Infants were randomly assigned to receive orally either BLF (100 mg/day) alone (group LF; n = 247) or with LGG (at 6×10(9) CFU/day; group BLF + LGG; n = 238), or placebo (Control group; n = 258) from birth until day 30 of life (45 for neonates <1000 g at birth). MAIN OUTCOME MEASURES: ≥ stage 2 NEC; death-and/or-≥ stage 2 NEC prior to discharge. RESULTS: Demographics, clinical and management characteristics of the 3 groups were similar, including type of feeding and maternal milk intakes. NEC incidence was significantly lower in groups BLF and BLF + LGG [5/247 (2.0%)] and 0/238 (0%), respectively] than in controls [14/258 (5.4%)] (RR = 0.37; 95% CI: 0.136-1.005; p = 0.055 for BLF vs. control; RR = 0.00; p < 0.001 for BLF + LGG vs. control). The incidence of death-and/or-NEC was significantly lower in both treatment groups (4.0% and 3.8% in BLF and BLF + LGG vs. 10.1% in control; RR = 0.39; 95% CI: 0.19-0.80; p = 0.008. RR = 0.37; 95% CI: 0.18-0.77; p = 0.006, respectively). No adverse effects or intolerances to treatment occurred. CONCLUSIONS AND RELEVANCE: Compared with placebo, BLF supplementation alone or in combination with LGG reduced the incidence of ≥ stage 2 NEC and of death-and/or ≥ stage 2 NEC in VLBW neonates. BLF might be a promising strategy to prevent NEC in NICU settings. Further data on larger sample sizes are warranted before BLF can be widespreadly used in clinical settings.

BACKGROUND: Retinopathy of prematurity (ROP) is a multifactorial disease, but little is known about its relationships with neonatal nutritional policies. Human, maternal milk is the best possible nutritional option for all premature infants, including those at high risk for severe complications of prematurity, such as ROP. OBJECTIVE: This is a secondary analysis of data collected during two multicenter RCTs performed consecutively (years 2004 through 2008) by a network of eleven tertiary NICUs in Italy. The two trials aimed at assessing effectiveness of fluconazole prophylaxis (Manzoni et al., N Engl J Med 2007 Jun 14;356(24):2483-95), and of bovine lactoferrin supplementation (Manzoni et al., JAMA 2009 Oct 7;302(13):1421-8), in prevention of invasive fungal infection, and of late-onset sepsis in VLBW infants, respectively. We tested the hypothesis that exclusive feeding with fresh maternal milk may prevent ROP of any stage - as defined by the ETROP study - in VLBW neonates, compared to formula feeding. METHODS: We analyzed the database from both trials. Systematic screening for detection of ROP was part of the protocol of both studies. The definition of threshold ROP was as defined by the ETROP study. Univariate analysis was performed to look for significant associations between ROP and several possible associated factors, and among them, the type of milk feeding (maternal milk or formula for preterms). When an association was indicated by p < 0.05, multiple logistic regression was used to determine the factors significantly associated with ROP. RESULTS: In both trials combined, 314 infants received exclusively human maternal milk (group A), and 184 a preterm formula because their mothers were not expected to breastfeed. The clinical, demographical and management characteristics of the neonates did not differ between the two groups, particularly related to the presence of the known risk factors for ROP. Overall, ROP incidence (any stage) was significantly lower in infants fed maternal milk (11 of 314; 3.5%) as compared to formula-fed neonates (29 of 184; 15.8%) (RR 0.14; 95% CI 0.12-0.62; p = 0.004). The same occurred for threshold ROP (1.3% vs. 12.3%, respectively; RR 0.19; 95% CI 0.05-0.69; p = 0.009). At multivariate logistic regression controlling for potentially confounding factors that were significantly associated to ROP (any stage) at univariate analysis (birth weight, gestational age, days on supplemental oxygen, systemic fungal infection, outborn, hyperglycaemia), type of milk feeding retained significance, human maternal milk being protective with p = 0.01. CONCLUSIONS: Exclusive human, maternal milk feeding since birth may prevent ROP of any stage in VLBW infants in the NICU.

BACKGROUND: Lactoferrin is a mammalian milk glycoprotein involved in innate immunity. Recent data show that bovine lactoferrin (bLF) prevents late-onset sepsis in preterm very low birth weight (VLBW) neonates. METHODS: This is a secondary analysis of data from a multicenter randomized controlled trial where preterm VLBW neonates randomly received bLF (100 mg/day; group A1), bLF + Lactobacillus rhamnosus GG (10(6) colony-forming units per day; group A2), or placebo (group B) for 6 weeks. Here we analyze the incidence rates of fungal colonization, invasive fungal infection (IFI), and rate of progression from colonization to infection in all groups. RESULTS: This study included 472 neonates whose clinical, nutritional, and demographical characteristics were similar. Overall, the incidence of fungal colonization was comparable (17.6%, 16.6%, and 18.5% in A1, A2, and B, respectively; P = .89 [A1] and .77 [A2]). In contrast, IFIs were significantly decreased in A1 and A2 (0.7% and 2.0%, respectively) compared with B (7.7%; P = .002 [A1] and .02 [A2]), and this was significantly true both in <1000 g (0.9% [A1] and 5.6% [A2], vs 15.0%) and in 1001 to 1500 g infants (0% and 0% vs 3.7%). The progression rate colonization-infection was significantly lower in the bLF groups: 3.7% (A1) and 12% (A2), vs 41.9%; P < .001 (A1) and P = .02 (A2). No IFI-attributable deaths occurred in the treatment groups, versus 2 in placebo. No adverse effects or intolerances occurred. CONCLUSIONS: Prophylactic oral administration of bLF reduces the incidence of IFI in preterm VLBW neonates. No effect is seen on colonization. The protective effect on IFI is likely due to limitation of ability of fungal colonies to progress toward invasion and systemic disease in colonized infants.
