Background: Bronchopulmonary dysplasia (BPD) remains a significant challenge in neonatal care. Prenatal inflammation and neonatal sepsis contribute to the multifactorial nature of BPD. A potential association between empirical antibiotic therapy and BPD risk has been proposed due to microbiota dysbiosis in very low birth weight premature infants., Methods: A single centered retrospective cohort study of preterm infants (24-32 weeks gestation) from 2014 to 2021. The study compared groups that received empirical antibiotics in the first days of life and those that did not receive any antibiotic in the first days of life. The primary outcomes studied were BPD, death, and the combined outcome of BPD/death. Statistical analysis employed t-tests, Mann-Whitney U, Chi-square, and logistic regression., Results: Of 454 preterm infants, 61.5% received antibiotics. This group had lower gestational age, birth weight, and Apgar scores. Antibiotic use was associated with higher incidence of BPD (35.5% vs. 10.3%), death (21.5% vs. 8.6%), and combined outcomes (54.5% vs. 18.3%). In multivariate analysis, antibiotic use independently associated with BPD (OR 2.58, p < 0.001) and combined outcome BPD/death (OR 2.06, p < 0.02). Antenatal corticosteroids provided protection against BPD, but not mortality., Conclusion: This study suggests an association between early empirical antibiotic use and BPD in preterm infants, emphasizing the need for judicious antibiotic practices in neonatal care., (© 2024 Wiley Periodicals LLC.)

Background: Preterm children are a risk group for neurodevelopmental delays, while interactions with their mothers may serve as a protective factor., Aims: The objectives of this study were to (1) identify changes in preterm children's neurodevelopment, maternal skills, and mother-child interactions of preterm children from the first to the second year of life; (2) analyze differences between preterm children with and without developmental delays in relation to social skills, parenting skills, and mother-child interaction; and (3) examine the risk and protective factors associated with the neurodevelopment of preterm children., Methods: Participants included 47 Brazilian preterm children and their mothers, assessed at the first (Mage/months = 10.4, SD =3.6) and second (Mage/months= 26.2, SD=8.5) years of life, using corrected age. The Bayley Scale of Infants and Toddler Development -III and the Interaction Rating Scale were used for assessment., Results: Cognitive and language scores decreased from the first to the second year of life, while children's motor and social skills, parenting skills, and mother-child interactions remained stable. In the second year of life, neurodevelopmental delays were associated with lower social skills, reduced parenting skills, and less evident mother-child interactions. Significant factors influencing child neurodevelopment in the first year of life included the number of children at home, NICU stays, maternal age, and parenting practices that foster cognitive growth. In the second year, neurodevelopment was primarily influenced by mother-child interactions and breastfeeding. Additionally, the number of children at home, child autonomy, responsiveness to the mother, breastfeeding, and family income were predictors of neurodevelopment in the second year., Conclusion: The results underscore the importance of enhancing mother-child interactions and parenting skills to promote neurodevelopment in premature children. The findings provide valuable insights for intervention programs targeting social skills, aimed at fostering positive peer interactions and facilitating social integration among children with developmental challenges., Competing Interests: Declaration of Competing Interest The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Elsevier Inc.

Objectives: To examine trends over time in diet and size of very preterm infants, and associations of diet with size at hospital discharge/transfer., Methods: The authors studied 4062 surviving very preterm infants born < 32 weeks' gestational age and < 1500 g between January 2012 and December 2020 from 12 Brazilian Neonatal Intensive Care Units. Diet type at discharge/transfer was classified as exclusive human milk, exclusive formula, or mixed. Outcomes were weight and head circumference at hospital discharge and the change in each from birth to discharge. The authors used linear regression to estimate adjusted associations of diet type with infant size, overall, and stratified by fetal growth category (small vs. appropriate for gestational age). The authors also examined trends in diet and infant size at discharge over the years., Results: Infants' mean gestational age at birth was 29.3 weeks, and the mean birth weight was 1136 g. Diet at discharge/transfer was exclusive human milk for 22 %, mixed for 62 %, and exclusive formula for 16 %. Infant size in weight and head circumference were substantially below the growth chart reference for all diets. Infants fed human milk and mixed diets were lighter and had smaller heads at discharge/transfer than infants fed formula only (weight z: -2.0, -1.8, and -1.5; head z: -1.3, -1.2 and -1.1 for exclusive human milk, mixed and exclusive formula respectively)., Conclusion: Results suggest high human milk use but gaps in nutrient delivery among hospitalized Brazilian very preterm infants, with little evidence of improvement over time., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2024 Sociedade Brasileira de Pediatria.

Objective: This study aimed to investigate the association between variations in cytokine levels in the first 72 hours of life and prematurity., Study Design: In this prospective study, we examined the cytokine levels of 110 newborns in the first 72 hours of life. The participants were divided into two groups based on gestational age (66 very preterm and 44 term newborns), and cytokine levels (interleukin [IL]-6, IL-8, and IL-10, tumor necrosis factor-α [TNF-α], and transforming growth factor-β [TGF-β]) were evaluated., Results: Premature newborns exhibited higher levels of IL-6, IL-8, and IL-10, while TNF-α and TGF-β levels were lower comparing to term newborns. Even after adjusting for maternal and peripartum factors, the significant differences persisted., Conclusion: Our study underscores significant cytokine profile differences between full-term and very preterm newborns in early life. Elevated IL-6 and IL-8 levels in preterm infants suggest potential perinatal inflammation links to prematurity., Key Points: · There is a direct association between cytokine levels and prematurity.. · Knowledge of the variation of cytokines in newborns enhances personalized interventions.. · Cytokine levels are early associated with gestational age., Competing Interests: None declared., (Thieme.

This study aimed to review the prevalence of developmental coordination disorder (DCD) in individuals born preterm and systematically explore this prevalence according to gestational age and different assessment cut-offs and compare it to full-term peers. The eligibility criteria were observational and experimental studies reporting the prevalence of DCD in preterm individuals. A systematic search was performed in databases from inception until March 2022. Two independent reviewers performed the selection. Study quality assessment was performed using the checklists from Joanna Briggs Institute (JBI). Data analysis was performed on Excel and Review Manager Software 5.4. Among the 1774 studies identified, 32 matched the eligibility criteria. The pooled estimate rate of the DCD rate in preterm was 21% (95% confidence interval [CI] 17.8-24.3). The estimate rates were higher as gestational age decreased, and preterm children are two times more likely to have DCD than their full-term peers risk ratio (RR) 2.2 (95% CI 1.77-2.79). The limitation was high heterogeneity between studies; the assessment tools, cut-off points and age at assessment were diverse. This study provided evidence that preterm children are at higher risk for DCD than full-term children, and the risks increased as gestational age decreased., (© 2024 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.)

Bacillus Calmette-Guerin (BCG) vaccination and tuberculosis (TB) incidence in children under 1 year of age are critical public health indicators in Brazil. The coronavirus disease 2019 pandemic disrupted vaccination coverage (VC), potentially impacting TB incidence. Understanding regional disparities in VC and TB incidence can inform targeted interventions. We conducted an observational and ecological study using BCG vaccination data (2019-21) and TB incidence (2020-22) for all births in Brazil. Data were collected from public health databases, stratified by state, and analyzed using descriptive and analytical statistics to explore VC and TB incidence. Between 2019 and 2021, average BCG VC was 79.59%, with significant variation among states (P < .001). Only four states achieved minimum recommended coverage (>90%). TB incidence varied significantly among states (P = .003). There was a notable decline in VC from 2019 (90.72%) to 2021 (78.67%) (P < .001). This study highlights regional disparities in BCG VC and TB incidence among Brazilian states. Lower VC post-pandemic may increase TB incidence, requiring targeted interventions in states with inadequate coverage. The findings underscore the importance of sustaining vaccination programs amidst public health crises and implementing strategies to enhance access and uptake., (© The Author(s) [2024].

To assess the ideal time for caffeine administration in preterms, identifying its effects and safety. Study Design: Meta-analysis conducted including preterms <32 weeks GA or BW < 1500 g, comparing caffeine administration time: <24 x ≥24HOL, <48 x ≥48HOL, <72 x ≥72HOL. 18 studies included 76.998 patients. The median age of starting caffeine was the first 24 HOL. In the overall comparisons, there was reduction in patent ductus arteriosus (OR 0.71 [0.55, 0. 92]; low evidence), retinopathy of prematurity (OR 0.71 [0.54, 0.93]; moderate evidence), severe brain injury (OR 0.79 [0.70, 0.91]; moderate evidence), bronchopulmonary dysplasia (BPD) (OR 0.69 [0.59, 0.81]; moderate evidence), composite outcome of BPD or death (OR 0.76 [0.66, 0.88]; moderate evidence). Mortality increase was found (OR 1.20 [1.12, 1.29], very low evidence).Caffeine in the first 24 HOL has benefits in reducing morbidities associated with prematurity. Mortality finding is potentially due to survival bias., (© 2024. The Author(s), under exclusive licence to Springer Nature America, Inc.)

Importance: Early interventions improve neurodevelopmental outcomes after preterm birth, but few studies of early intervention have focused on preterm infants whose families reside in low- or middle-income countries (LMICs)., Objective: To evaluate whether parent-guided early intervention improves the neurodevelopmental outcomes of preterm infants in an LMIC., Design, Setting, and Participants: This randomized clinical trial was performed at a high-risk obstetric referral hospital in Brazil, with outcome evaluations by examiners masked to randomization group. Eligibility criteria were (1) birth at the study hospital, (2) residence within 40 km of the birth hospital, and (3) gestational age of less than 32 weeks or birth weight of less than 1500 g. Of 138 enrolled infants, 19 died after randomization and 19 withdrew from the study; all other enrollees (50 per randomization group) were evaluated for the primary outcome. Data were collected from January 1, 2016, to May 31, 2022, and analyzed from June 10 to July 31, 2022., Interventions: On postnatal day 7, infants were randomized to usual care, consisting of support for lactation, kangaroo care, and routine developmental therapies, or to a parent-guided enhanced developmental intervention, consisting of usual care plus infant massage and enhanced visual stimulation, auditory stimulation, social interactions, and support for motor development, instructed by developmental therapists., Main Outcomes and Measures: The primary outcome was the Bayley Scales of Infant and Toddler Development-Third Edition score at 18 months of age adjusted for prematurity., Results: Among the 100 infants included in the analysis, mean (SD) gestational age was 28.4 (2.2) weeks, and 57 (57%) were male. The mean (SD) gestational age for the intervention group was 28.3 (2.3) weeks; for the usual care group, 28.5 (2.2) weeks. Female infants accounted for 21 infants (42%) of the intervention group and 22 (44%) of the usual care group; male infants, 29 (58%) and 28 (56%), respectively. The enhanced developmental intervention group had higher cognitive scores at 18 months of corrected age (mean [SD], 101.8 [11.9] vs 97.3 [13.5]; mean difference, 4.5 [95% CI, 0.1-8.9])., Conclusions and Relevance: In this randomized clinical trial of a parent-guided developmental intervention for early cognitive function of very preterm or very low birth weight infants implemented in an LMIC, the intervention improved very preterm infants' neurodevelopmental outcomes at 18 months of adjusted age. Parent-guided early intervention can improve neurodevelopmental outcome of very preterm infants born in LMICs., Trial Registration: ClinicalTrials.gov Identifier: NCT02835612.

Background: Although approximately 25% of Brazilians have private health coverage (PHC), studies on the surveillance of chronic kidney disease (CKD) in this population are scarce. The objective of this study was to estimate the prevalence of CKD in individuals under two PHC regimes in Brazil, who total 8,335,724 beneficiaries., Methods: Outpatient serum creatinine and proteinuria results of individuals from all five regions of Brazil, ≥ 18 years of age, and performed between 10/01/2021 and 10/31/2022, were analyzed through the own laboratory network database. People with serum creatinine measurements were evaluated for the prevalence and staging of CKD, and those with simultaneous measurements of serum creatinine and proteinuria were evaluated for the risk category of the disease. CKD was classified according to current guidelines and was defined as a glomerular filtration rate (GFR) < 60 ml/min/1.73 m² estimated by the 2021 CKD-EPI equation., Results: The number of adults with serum creatinine results was 1,508,766 (age 44.0 [IQR, 33.9-56.8] years, 62.3% female). The estimated prevalence of CKD was 3.8% (2.6%, 0.8%, 0.2% and 0.2% in CKD stages 3a, 3b, 4 and 5, respectively), and it was higher in males than females (4.0% vs. 3.7%, p < 0.001, respectively) and in older age groups (0.2% among 18-29-year-olds, 0.5% among 30-44-year-olds, 2.0% among 45-59-year-olds, 9.4% among 60-74-year-olds, and 32.4% among ≥ 75-year-olds, p < 0.001) Adults with simultaneous results of creatinine and proteinuria were 64,178 (age 57.0 [IQR, 44.8-67.3] years, 58.1% female). After adjusting for age and gender, 70.1% were in the low-risk category of CKD, 20.0% were in the moderate-risk category, 5.8% were in the high-risk category, and 4.1% were in the very high-risk category., Conclusion: The estimated prevalence of CKD was 3.8%, and approximately 10% of the participants were in the categories of high or very high-risk of the disease. While almost 20% of beneficiaries with PHC had serum creatinine data, fewer than 1% underwent tests for proteinuria. This study was one of the largest ever conducted in Brazil and the first one to use the 2021 CKD-EPI equation to estimate the prevalence of CKD., (© 2024. The Author(s).)

Objectives: To make recommendations on the diagnosis and treatment of post-extubation laryngitis (PEL) in children with or without other comorbidities., Methods: A three-iterative modified Delphi method was applied. Specialists were recruited representing pediatric otolaryngologists, pediatric and neonatal intensivists. Questions and statements approached topics encompassing definition, diagnosis, endoscopic airway evaluation, risk factors, comorbidities, management, and follow-up. A consensus was defined as a supermajority >70%., Results: Stridor was considered the most frequent symptom and airway endoscopy was recommended for definitive diagnosis. Gastroesophageal reflux and previous history of intubation were considered risk factors. Specific length of intubation did not achieve a consensus as a risk factor. Systemic corticosteroids should be part of the medical treatment and dexamethasone was the drug of choice. No consensus was achieved regarding dosage of corticosteroids, although endoscopic findings help defining dosage and length of treatment. Non-invasive ventilation, laryngeal rest, and use of comfort sedation scales were recommended. Indications for microlaryngoscopy and bronchoscopy under anesthesia were symptoms progression or failure to improve after the first 72-h of medical treatment post-extubation, after two failed extubations, and/or suspicion of severe lesions on flexible fiberoptic laryngoscopy., Conclusions: Management of post-extubation laryngitis is challenging and can be facilitated by a multidisciplinary approach. Airway endoscopy is mandatory and impacts decision-making, although there is no consensus regarding dosage and length of treatment., (Copyright © 2024 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Objective: To evaluate the success rate of high-flow nasal cannula (HFNC) therapy using an adapted obsolete mechanical ventilator (MV), Optiflow™ and Vapotherm™ in newborns (NBs)., Method: This was a retrospective observational study conducted in the neonatal intensive care unit (NICU). The sample comprised NBs who underwent HFNC therapy due to ventilatory dysfunction, for weaning from non-invasive ventilation (NIV), or post-extubation. The three groups, stratified according to gestational age (GA) and birth weight, and corrected GA and weight at the beginning of HFNC use, were as follows: Optiflow ™, Vapotherm ™, and obsolete Mechanical Ventilator (MV) adapted for high flow therapy. Subsequently, the NBs were divided into a success group (SG) and a failure group (FG). HFNC success was defined as a therapy duration exceeding 72 h., Results: A total of 209 NBs were evaluated, with 31.1 % using HFNC due to ventilatory dysfunction, 2.4 % after extubation, and 66.5 % after NIV weaning. HFNC success rate was observed in 90.9 % of the NBs, with no difference between equipment types (Vapotherm ™, Optiflow ™, and adapted VM)., Conclusion: Different types of HFNC equipment are equally effective when used in neonatology for respiratory dysfunction, as a method of weaning from NIV and post-extubation. Adapted obsolete MV can be an alternative for HFCN therapy in resource-constrained settings., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2023 Sociedade Brasileira de Pediatria.

Objectives: To compare LISA with INSURE technique for surfactant administration in preterm with gestational age (GA) < 36 weeks with RDS in respect to the incidence of pneumothorax, bronchopulmonary dysplasia (BPD), need for mechanical ventilation (MV), regional cerebral oxygen saturation (rSO2), peri‑intraventricular hemorrhage (PIVH) and mortality., Methods: A systematic search in PubMed, Embase, Lilacs, CINAHL, SciELO databases, Brazilian Registry of Randomized Clinical Trials (ReBEC), Clinicaltrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL) was performed. RCTs evaluating the effects of the LISA technique versus INSURE in preterm infants with gestational age < 36 weeks and that had as outcomes evaluation of the rates of pneumothorax, BPD, need for MV, rSO2, PIVH, and mortality were included in the meta-analysis. Random effects and hazard ratio models were used to combine all study results. Inter-study heterogeneity was assessed using Cochrane Q statistics and Higgin's I2 statistics., Results: Sixteen RCTs published between 2012 and 2020 met the inclusion criteria, a total of 1,944 preterms. Eleven studies showed a shorter duration of MV and CPAP in the LISA group than in INSURE group. Two studies evaluated rSO2 and suggested that LISA and INSURE transiently affect brain autoregulation during surfactant administration. INSURE group had a higher risk for MV in the first 72 h of life, pneumothorax, PIVH and mortality in comparison to the LISA group., Conclusion: This systematic review and meta-analyses provided evidence for the benefits of the LISA technique in the treatment of RDS, decreasing CPAP time, need for MV, BPD, pneumothorax, PIVH, and mortality when compared to INSURE., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2023 Sociedade Brasileira de Pediatria.

Premature infants, given their limited reserves, heightened energy requirements, and susceptibility to nutritional deficits, require specialized care., Aim: To examine the complex interplay between nutrition and neurodevelopment in premature infants, underscoring the critical need for tailored nutritional approaches to support optimal brain growth and function., Data Sources: PubMed and MeSH and keywords: preterm, early nutrition, macronutrients, micronutrients, human milk, human milk oligosaccharides, probiotics AND neurodevelopment or neurodevelopment outcomes. Recent articles were selected according to the authors' judgment of their relevance. Specific nutrients, including macro (amino acids, glucose, and lipids) and micronutrients, play an important role in promoting neurodevelopment. Early and aggressive nutrition has shown promise, as has recognizing glucose as the primary energy source for the developing brain. Long-chain polyunsaturated fatty acids, such as DHA, contribute to brain maturation, while the benefits of human milk, human milk oligosaccharides, and probiotics on neurodevelopment via the gut-brain axis are explored. This intricate interplay between the gut microbiota and the central nervous system highlights human milk oligosaccharides' role in early brain maturation., Conclusions: Individualized nutritional approaches and comprehensive nutrient strategies are paramount to enhancing neurodevelopment in premature infants, underscoring human milk's potential as the gold standard of nutrition for preterm infants.

The objective of this study is to examine the association between preterm infants' size at 1 year and attention-deficit/hyperactivity disorder (ADHD) assessed categorically and dimensionally in childhood and adolescence. We studied infants born < 37 weeks' gestation from two Brazilian birth cohorts (n = 653). ADHD was evaluated using the Development and Well-Being Assessment (DAWBA) interview at the age of 6 years in one cohort and by a structured interview according to DSM-5 criteria at 18 years in the other one. The presence of child attention difficulties was measured by the Strengths and Difficulties Questionnaire (SDQ) at 6 and 11 years in the 2004 and 1993 cohorts, respectively. We estimated associations of weight, length, head circumference, and BMI z-scores at 1-year chronological age with ADHD using Poisson Regression Model; and with attention difficulties using Linear Regression, adjusting for covariates. Mean birth weight was 2500 g and gestational age was 34.5 weeks. The aggregated ADHD prevalence in the two cohorts was 2.7%, and the median score for attention difficulties was 3.0. We found that increased head circumference at 1 year was associated with a lower risk of ADHD diagnosis (RR = 0.7, 95% CI 0.4, 0.9; p = 0.04 per standard deviation difference) and with fewer dimensional attention symptoms. In sensitivity analysis with other mental disorders, head circumference was associated with depression, but not with anxiety. Our findings emphasize poor head growth in the first year of life as a potential determinant of attentional difficulties in the preterm infant population., (© 2022.

Objective: The aim of this study was to evaluate the incidence of nasal injury in preterm newborns (NB) using the Neonatal Skin Condition Score within 7 days of noninvasive ventilation (NIV) and to compare the incidence of injury in NB weighing ≥1,000 g and those weighing <1,000 g at the time of initiation of NIV support., Methods: This is a prospective, observational study carried out in a neonatal intensive care unit of a public hospital in Rio Grande do Sul from July 2016 to January 2021. Patients were stratified into two groups at the time of NIV initiation: group 1 (weight ≥1,000 g) and group 2 (weight <1,000 g). To assess the condition of nasal injury, a rating scale called the Neonatal Skin Condition Score was applied during the first seven consecutive days on NIV. Kaplan-Meier, log-rank test, and Cox proportional hazards regression were used to estimate the hazard ratio (HR) and 95% confidence interval (CI)., Results: In total, 184 NB were evaluated. Nasal injury was reported in 55 (30%) NB. The risk of nasal injury was 74% higher in group 2 (19/45) than in group 1 (36/139) (HR: 1.74; 95%CI 0.99-3.03, p=0.048)., Conclusion: The incidence of nasal injury in infants submitted to NIV by nasal mask was high, and the risk of this injury was greater in preterm infants weighing <1,000 g.

The objective was to analyze the mortality of Bolivian immigrants compared to the Brazilian population, living in the city of São Paulo, with an emphasis on the analysis of avoidable deaths. Descriptive study of deaths in the city of São Paulo, between 2007 and 2018, registered in the Mortality Information System. Deaths of people aged 5 to 74 years were analyzed, according to "Brazilian List of Causes of Preventable Deaths", according to groups and sex; Pearson's chi-square test was used to compare nationalities. The temporal trend of avoidable deaths was evaluated by Prais-Winsten regression. There were 1.123 Bolivians deaths and 883.116 among Brazilians, with a predominance of male deaths and the Bolivians died on average 13.6 years younger. The proportion of deaths from preventable causes was similar between Bolivians (71.0%) and Brazilians (72.8%) and the trend did not show significant proportional annual variation for both nationalities. There is a higher frequency, among Bolivians, of external causes (27.6%) and of causes reducible by actions to health promotion, prevention, control, and care for infectious diseases (20.8%) than to Brazilians. Conclusion: Bolivians died younger and showed no reduction in the proportion of potentially avoidable causes, which may indicate unequal access to health services.

Objective: To assess the predictive value of selected growth phenotypes for neonatal morbidity and mortality in preterm infants < 30 weeks and to compare them with INTERGROWTH-21 st (IG21)., Method: Retrospective analysis of data from the Brazilian Neonatal Research Network (BNRN) database for very low birth weight (VLBW) at 20 public tertiary-care university hospitals., Outcome: the composite neonatal morbidity and mortality (CNMM) consisted of in-hospital death, oxygen use at 36 weeks, intraventricular hemorrhage grade 3 or 4, and Bell stage 2 or 3 necrotizing enterocolitis. Selected growth phenotypes: small-for-gestational-age (SGA) defined as being < 3 rd (SGA3) or 10 th (SGA10) percentiles of BW, and large-for-gestational-age (LGA) as being > 97 th percentile of BW. Stunting as being < 3 rd percentile of the length and wasting as being < 3 rd percentile of BMI. Single and multiple log-binomial regression models were fitted to estimate the relative risks of CNMM, comparing them to IG21., Results: 4,072 infants were included. The adjusted relative risks of CNMM associated with selected growth phenotypes were (BNRN/IG21): 1.45 (0.92-2.31)/1.60 (1.27-2.02) for SGA; 0.90 (0.55-1.47)/1.05 (0.55-1.99) for LGA; 1.65 (1.08-2.51)/1.58 (1.28-1.96) for stunting; and 1.48 (1.02-2.17) for wasting. Agreement between the two references was variable. The growth phenotypes had good specificity (>95%) and positive predictive value (70-90%), with poor sensitivity and low negative predictive value., Conclusion: The BNRN phenotypes at birth differed markedly from the IG21 standard and showed poor accuracy in predicting adverse neonatal outcomes., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2022 Sociedade Brasileira de Pediatria.

Background and Aims: Early child interventions focused on the family prevented neurodevelopmental and behavioral delays and can provide more knowledge regarding responsive feeding, thus creating learning opportunities to promote better quality nutrition and preventing failure to thrive. The aim is to verify the impact of a continuous program of early home-based intervention on the body composition of preschool infants who were born preterm with very low birth weight (VLBW)., Methods: This is a longitudinal analysis from a randomized controlled trial, including VLBW preterm children, born in a tertiary hospital in Southern Brazil and followed up at the high-risk institutional ambulatory clinic. Participants were divided into the intervention group (IG): skin-to-skin care with the mother (kangaroo care), breastfeeding policy, and tactile-kinesthetic stimulation by mothers until hospital discharge. Subsequently, they received a program of early intervention with orientation and a total of 10 home visits, independently from the standard evaluation and care that was performed following the 18 months after birth; conventional group (CG): standard care according to the routine of the newborn intensive care unit (NICU), which includes kangaroo care, and attending to their needs in the follow-up program. Body composition estimation was performed using bioelectrical impedance analyses (BIA), and physical activity and feeding practices questionnaires were evaluated at preschool age, as well as anthropometric measurements and biochemical analysis., Results: Data of 41 children at 4.6 ± 0.5 years old were evaluated (CG n = 21 and IG n = 20). Body weight, height, body mass index, waist and arm circumferences, and triceps and subscapular skinfold did not differ between groups. The IG presented higher segmented fat-free mass (FFM) when compared to the CG (right arm FFM: 0.74 vs. 0.65 kg, p = 0.040; trunk FFM: 6.86 vs. 6.09 kg, p = 0.04; right leg FFM: 1.91 vs. 1.73 kg, p = 0.063). Interaction analyses showed that segmented FFM and FFM Index were associated with higher iron content in the IG. In the CG, interaction analyses showed that increased visceral fat area was associated with higher insulin resistance index., Conclusion: An early intervention protocol from NICU to a home-based program performed by the mothers of VLBW preterm children of low-income families presents a small effect on FFM., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Fernandes, Bernardi, da Fonseca, Gomes da Silva, Procianoy and Silveira.)

Purpose: Early identification of impairments is crucial to providing better care for preterm children, especially those from low-income families. The early motor assessment is the first step in monitoring their neurodevelopment. This study investigates if motor development in the first year of life predicts impairments in cognition and language at 3-year-old in a Brazilian preterm cohort., Materials and Methods: Data were collected in a follow-up clinic for high-risk infants. The Bayley Scales were used to assess children at 4, 8, 12, and 36 months of age, considering composite scores. Cognitive and language impairments were considered if scores were ≤85. Children ( N = 70) were assessed at 4 and 36 months, 79 were assessed at 8 and 36 months, and 80 were assessed at 12 and 36 months. Logistic regressions were used to analyze the predictability of cognitive and language impairments, and receiver-operating characteristics (ROC) curves were used to analyze the sensibility and specificity of motor assessment and cognitive and language impairments., Results: Poor motor scores at 8 and 12 months increased the chances of cognitive and language impairment at 3-year-old. The chance of cognitive impairment at 3-year-old increases by 6-7% for each point that the motor composite score decreases, and the chance of language impairment at 3-year-old increases by 4-5% for each point that the motor composite score decreases. No-significant results were found at 4-months. Adequate sensibility and specificity were found for language impairments considering 12 months scores and for cognitive impairments as soon as 8 months scores., Conclusion: Monitoring preterm motor development in the first year of life helps to identify preterm children at risk for impairment in other developmental domains. Since preterm children from low-income families tend to demonstrate poorer neurodevelopment outcomes, these children need early assessment and referral to intervention to prevent school failures and support from public policies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Panceri, Silveira, Procianoy and Valentini.)

Objective: To perform a longitudinal investigation of risk factors in premature infants' cognitive, motor, and language development., Methods: Thirty-three preterm infants were assessed at 4, 8, and 12 months of corrected age, using the Bayley-III Scales. Parents completed questionnaires regarding development opportunities at home, parenting practices and knowledge., Results: Significant associations were found (1) at 4-months between cognitive scores and family income, variety of stimuli, availability of toys, parenting practices and knowledge; language and parenting practices; and motor skills and parenting practices; (2) at 8-months between cognitive score and length of stay in the Neonatal Intensive Care Unit (NICU), gestational age, birth weight, toys, and parenting knowledge; language and toys; and motor skills and toys and parenting knowledge; (3) at 12-months between cognitive scores and length of stay in the NICU, family income, breastfeeding, toys, and parenting knowledge; language and income and toys; and motor scores and length of stay in the NICU, gestational age, income, stimuli, toys, and parenting knowledge. Regression analyses indicated that: for (1) cognitive development, stimulus variety explained 72% of the model variance at 4 months of age; time at the NICU explained 67 and 43% at 8 and 12 months of age, respectively, and breastfeeding time explained 41% of the model variance at 12 months; (2) for language development, family income explained 42% of the model variance at 12 months; and for motor development (3), time at the NICU explained 80% of the model variance at 12 months., Conclusions: The development over the first year of life is not explained by the severity of birth conditions and associated morbidities only, but also by parenting practices.

Objectives: To evaluate neonatal autopsy rates at a tertiary hospital in southern Brazil ascertain the level of agreement between premortem and postmortem diagnosis., Methods: The authors reviewed all neonatal autopsies performed over a 10-year period and described the percentage of neonates who died and underwent autopsy. The authors tested for agreement between autopsy findings and the cause of death as defined by the neonatologist. Agreement between clinical diagnosis and autopsy findings was classified using the modified Goldman criteria. Additional findings at autopsy were grouped by organ system. Linear regression and multiple comparisons were used for statistical analyses., Results: During the study period, 382 neonates died at the Neonatal Intensive Care Unit (NICU). Consent to perform an autopsy was obtained for 73 (19.1%). The complete agreement between autopsy findings and the neonatologist's premortem diagnosis was found in 48 patients (65.8%). Additional findings were obtained at autopsy in 25 cases (34.2%). In 5 cases (6.9%), the autopsy findings contributed to subsequent genetic counseling. Seven autopsies (9.6%) revealed a diagnosis that would have changed patient management if established premortem. The autopsy rate increased by an average of 1.87% each year., Conclusion: Despite a high level of agreement between clinical diagnosis and pathological findings, autopsies provided relevant data regarding the cause of death, providing additional clinical information to neonatologists and allowing genetic counseling of family members., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2022 Sociedade Brasileira de Pediatria.

Background: Very preterm/very low birth weight (VP/VLBW) newborns can have lifelong morbidities, as attention-deficit/hyperactivity disorder (ADHD). Clinicians have no markers to discriminate which among those individuals will develop later ADHD, based only on the clinical presentation at birth. Our aim was to develop an individualized risk calculator for ADHD in VP/VLBW newborns., Methods: This retrospective prognostic study included a consecutive sample of all VP/VLBW children (gestational age <32 weeks and/or birth weight <1.5 kg) born between 2010 and 2012 from a clinical cohort in a Brazilian tertiary care hospital. Children were clinically assessed at 6 years of age for ADHD using the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS). The least absolute shrinkage and selection operator (LASSO) method was used for model-building., Results: Ninety-six VP/VLBW children were assessed at 6 years of age (92% follow-up), of whom 32 (33%) were diagnosed with ADHD. The area under the ROC curve (AUC) for ADHD prediction based on seven parameters (late-onset sepsis confirmed by blood culture, necrotizing enterocolitis, neonatal seizures, periventricular leukomalacia, respiratory distress syndrome, length of hospital stay, and number of maternal ADHD symptoms) was .875 (CI, 0.800-0.942, p < .001; AUC corrected for optimism with bootstrapping: .806), a performance that is comparable to other medical risk calculators. Compared to approaches that would offer early intervention to all, or intervention to none, the risk calculator will be more useful in selecting VP/VLBW newborns, with statistically significant net benefits at cost:benefits of around 1:2 to around 10:6 (range of ADHD risk thresholds of 32%-62%, respectively). It also showed specificity for ADHD compared to other prevalent child psychopathologies., Conclusions: The risk calculator showed good performance for early identification of VP/VLBW newborns at high risk of future ADHD diagnosis. External validity in population-based samples is needed to extend clinical usefulness., (© 2021 Association for Child and Adolescent Mental Health.)

Backgroud and Aims: Hypertension (HTN) is a multifactorial chronic disease. Considering the high prevalence rates of this disease, treatment of HTN is necessary, not only to reduce blood pressure (BP) levels but also to prevent the development of cardiovascular, cerebrovascular, and kidney diseases. This treatment can be through medication, which will be determined according to the BP values, obtained either in medical consultations or at home; presence of cardiovascular risk factors, and the presence of target organ damage identified during anamnesis. The aim of this systematic review and meta-analysis is to summarize the effects of device-guided slow breathing (DGSB) and nondevice-guided slow breathing (NDGSB) on BP levels of patients with HTN., Methods: This study is a systematic review and meta-analysis of randomized clinical trials, pertaining to hypertensive patients, with or without comorbidity, over 18 years old, of both sexes, and with or without hypertensive medication. The selected studies showed comparisons between groups that performed DGSB and/or NDGSB with control conditions. The primary outcome was the value of systolic blood pressure (SBP) and diastolic blood pressure (DBP) after the interventions., Results: Twenty-two studies involving 17,214 participants were included in the quantitative analysis. Considerable heterogeneity was revealed between studies. Using random effect model, it was found that DGSB did not significantly reduce SBP and DBP compared to usual care, both in terms BP values and in relation to their variations (SBP, mean difference [MD]: -2.13 mmHg, (95% confidence interval [CI]: -12.71 to 8.44), 288 individuals; I 2  = 93%, high heterogenity: DBP, MD: -0.90, 95% CI: -3.97 to 2.11, 288 individuals; I 2  = 63%, substantial heterogenity. SBP variations MD: -2.42, 95% CI: -7.24 to 2.40, 443 individuals; I 2  = 85% high heterogenity/DBP variations MD: -1.67, 95% CI: -4.57 to 1.24, 443 individuals; I 2  = 80%, high heterogenity)., Conclusion: Based on these results it appears that DGSB did not reduce BP in hypertensive patients and NDGSB is a new path for the future., Competing Interests: The authors declare no conflicts of interest., (© 2022 The Authors.

Background: Early-onset neonatal sepsis (EONS) remains one of the leading causes of morbidity and mortality related to premature birth, and its diagnosis remains difficult. Our goal was to evaluate the intestinal microbiota of the first meconium of preterm newborns and ascertain whether it is associated with clinical EONS., Methods: In a controlled, prospective cohort study, samples of the first meconium of premature infants with a gestational age (GA) ≤32 weeks was obtained at Hospital de Clínicas de Porto Alegre and DNA was isolated from the samples. 16S rDNA based microbiota composition of preterm infants with a clinical diagnosis of EONS was compared to that of a control group., Results: 40 (48%) premature infants with clinical diagnosis of EONS and 44 (52%) without EONS were included in the analysis. The most abundant phylum detected in both groups, Proteobacteria , was more prevalent in the sepsis group ( p  = .034). 14% of variance among bacterial communities ( p  = .001) correlated with EONS. The genera most strongly associated with EONS were Paenibacillus, Caulobacter, Dialister, Akkermansia, Phenylobacterium, Propionibacterium, Ruminococcus, Bradyrhizobium, and Alloprevotella . A single genus, Flavobacterium , was most strongly associated with the control group., Conclusion: These findings suggest that the first-meconium microbiota is different in preterm neonates with and without clinical EONS.

Aim: This study examined the neurodevelopment trajectories, the prevalence of delays, and the risks and protective factors (adverse outcomes, environment, and maternal factors) associated with cognitive, motor, and language development for preterm infants from 4- to 24-months. Method: We assessed 186 preterm infants (24.7% extremely preterm; 54.8% very preterm; 20.4% moderate/late preterm) from 4- to 24-months using the Bayley Scales of Infant Development - III. Maternal practices and knowledge were assessed using the Daily Activities of Infant Scale and the Knowledge of Infant Development Inventory. Birth risks and adverse outcomes were obtained from infant medical profiles. Results: A high prevalence of delays was found; red flags for delays at 24-months were detected at 4- and 8-months of age. The neurodevelopmental trajectories showed steady scores across time for cognitive composite scores for extremely- and very-preterm infants and for language composite scores for the extremely- and moderate/late-preterm; a similar trend was observed for the motor trajectories of moderate/late preterm. Changes over time were restricted to motor composite scores for extremely- and very-preterm infants and for cognitive composite scores for moderate/late preterm; declines, stabilization, and improvements were observed longitudinally. Positive, strong, and significant correlations were for the neurodevelopment scores at the first year of life and later neurodevelopment at 18 and 24 months. The cognitive, language, and motor composite scores of extremely and very preterm groups were associated with more risk factors (adverse outcomes, environment, and maternal factors). However, for moderate/late preterm infants, only APGAR and maternal practices significantly explained the variance in neurodevelopment. Discussion: Although adverse outcomes were strongly associated with infant neurodevelopment, the environment and the parents' engagement in play and breastfeeding were protective factors for most preterm infants. Intervention strategies for preterm infants should start at 4- to 8-months of age to prevent unwanted outcomes later in life., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Valentini, de Borba, Panceri, Smith, Procianoy and Silveira.)

Background: Global assessment of antimicrobial agents prescribed to infants in the neonatal intensive care unit (NICU) may inform antimicrobial stewardship efforts., Methods: We conducted a one-day global point prevalence study of all antimicrobials provided to NICU infants. Demographic, clinical, and microbiologic data were obtained including NICU level, census, birth weight, gestational/chronologic age, diagnoses, antimicrobial therapy (reason for use; length of therapy), antimicrobial stewardship program (ASP), and 30-day in-hospital mortality., Findings: On July 1, 2019, 26% of infants (580/2,265; range, 0-100%; median gestational age, 33 weeks; median birth weight, 1800 g) in 84 NICUs (51, high-income; 33, low-to-middle income) from 29 countries (14, high-income; 15, low-to-middle income) in five continents received ≥1 antimicrobial agent (92%, antibacterial; 19%, antifungal; 4%, antiviral). The most common reasons for antibiotic therapy were "rule-out" sepsis (32%) and "culture-negative" sepsis (16%) with ampicillin (40%), gentamicin (35%), amikacin (19%), vancomycin (15%), and meropenem (9%) used most frequently. For definitive treatment of presumed/confirmed infection, vancomycin (26%), amikacin (20%), and meropenem (16%) were the most prescribed agents. Length of therapy for culture-positive and "culture-negative" infections was 12 days (median; IQR, 8-14) and 7 days (median; IQR, 5-10), respectively. Mortality was 6% (42%, infection-related). An NICU ASP was associated with lower rate of antibiotic utilization ( p  = 0·02)., Interpretation: Global NICU antibiotic use was frequent and prolonged regardless of culture results. NICU-specific ASPs were associated with lower antibiotic utilization rates, suggesting the need for their implementation worldwide., Funding: Merck & Co.; The Ohio State University College of Medicine Barnes Medical Student Research Scholarship., Competing Interests: Dr. Pablo J.

Objectives: To evaluate the prevalence of congenital heart disease and their outcomes in a Brazilian cohort of very low birth weight preterm infants., Design: Post hoc analysis of data from the Brazilian Neonatal Network database, complemented by retrospective data from medical charts and a cross-sectional survey., Setting: Twenty public tertiary-care university hospitals., Patients: A total of 13,955 newborns weighing from 401 to 1,499 g and between 22 and 36 weeks of gestational age, born from 2010 to 2017., Interventions: None., Measurements and Main Results: The prevalence of congenital heart disease was 2.45% (95% CI, 2.20-2.72%). In a multivariate regression analysis, risk factors associated with congenital heart disease were maternal diabetes (relative risk, 1.55; 95% CI, 1.11-2.20) and maternal age above 35 years (relative risk, 2.09; 95% CI, 1.73-2.51), whereas the protection factors were maternal hypertension (relative risk, 0.54; 95% CI, 0.43-0.69), congenital infection (relative risk, 0.45; 95% CI, 0.21-0.94), and multiple gestation (relative risk, 0.73; 95% CI, 0.55-0.97). The pooled standardized mortality ratio in patients with congenital heart disease was 2.48 (95% CI, 2.22-2.80), which was significantly higher than in patients without congenital heart disease (2.08; 95% CI, 2.03-2.13). However, in multiple log-binomial regression analyses, only the presence of major congenital anomaly, gestational age (< 29 wk; relative risk, 2.32; 95% CI, 2.13-2.52), and Score for Neonatal Acute Physiology and Perinatal Extension II (> 20; relative risk, 3.76; 95% CI, 3.41-4.14) were independently associated with death, whereas the effect of congenital heart disease was spotted only when a conditional inference tree approach was used., Conclusions: The overall prevalence of congenital heart disease in this cohort of very low birth weight infants was higher and with higher mortality than in the general population of live births. The occurrence of a major congenital anomaly, gestational age (< 29 wk), and Score for Neonatal Acute Physiology and Perinatal Extension II (> 20) were significantly and independently associated with death, whereas the association of congenital heart disease and death was only evident when a major congenital anomaly was present., Competing Interests: The Brazilian Neonatal Network received funding from Brazilian Ministry of Health (Ministério da Saúde do Brasil).

Background: This study extended previous research by investigating the combined effects of neonatal birth risks, neonatal adverse outcomes, and socioeconomic status on preterm neurodevelopment., Method: A total of 184 preterm infants were assessed using the Bayley Scales of Infant Development III in a follow-up clinic in southern Brazil. Structural equation modeling was conducted with 3 latent variables (neonatal birth risks, neonatal adverse outcomes, and socioeconomic status) and 3 outcomes (cognitive, language, and motor development)., Results: The analyses showed that neonatal adverse outcomes were associated with infants' cognitive (b = -0.45, P < .001), language (b = -0.23, P = .001), and motor (b = -0.51, P < .001) development. Socioeconomic status also explained the variances (cognitive: b = 0.20, P = .006; language: b = 0.28, P = .001; and motor: b = 0.21, P = .004), whereas neonatal birth risks remained significant only in the motor development (b = 0.15, P = .040)., Conclusion: This study suggests that the most evident contributors to poor neurodevelopment were adverse outcomes and socioeconomic risk factors.

There is an increasing evidence that strict evaluation of clinical signs is effective in detecting newborns at risk of early-onset sepsis (EOS) that require antibiotic therapy. In a retrospective case control design, we compared EOS antibiotic indication by clinical signs surveillance with multivariate risk analysis (EOSCalc), and estimate their costs. Newborns ≥ 34 weeks who received EOS antibiotics from June 2014 to December 2016 were studied. Were considered symptomatic those with three clinical signs within first 24 h or two signs and one risk factor present. Cost estimative was done using bottom-up hospital's perspective. Eight thousand three hundred twenty-one were born, 384 were included. Two hundred nineteen (57%) would receive antibiotics by EOSCalc and 64 (16.7%) by clinical signs (p < 0.001). All patients with blood cultures were detected and false-negatives were absent. Total cost was US$ 574,121, estimate US$ 415,576 by EOSCalc, and US$ 314,353 by clinical signs (p < 0.001).Conclusions: The use of EOSCalc and clinical signs surveillance seem to be safe and accurate methods in EOS management. Additionally, the two approaches have shown an economic advantage when compared with the hospital's current practice. What is Known: • EOSCalc is a useful method for screening of EOS in late preterm and term infants. • Presence of clinical signs and/or maternal risk factors are present newborns with EOS. What is New: • Rigorous observation of clinical signs is a more accurate method than EOSCalc to screen for EOS in late preterm and term newborns. • Rigorous observation of clinical signs is more economic than EOSCalc in managing EOS in late preterm and term neonates.

Introduction: Deficits in executive functioning, especially in inhibitory control, are present in children born very premature and/or with very low birth weight (VP/VLBW) and in children with attention-deficit/hyperactivity disorder (ADHD)., Objective: To evaluate whether ADHD imposes additional inhibitory control (IC) deficits in preschoolers born VP/VLBW., Methods: 79 VP/VLBW (4 to 7 years) children were assessed for ADHD using the Schedule for Affective Disorders and Schizophrenia for School Aged Children - Present and Lifetime Version (K-SADS-PL). IC was measured with Conners' Kiddie Continuous Performance Test (K-CPT 2) and the Behavior Rating Inventory of Executive Function - Preschool Version (BRIEF-P).Results: No significant differences were found between ADHD (n = 24) and non-ADHD children (n = 55) for any of the measures (p = 0.062 to p = 0.903). Both groups had deficits in most K-CPT 2 scores compared to normative samples, indicating poor IC and inconsistent reaction times., Conclusions: ADHD does not aggravate IC deficits in VP/VLBW children. Either neuropsychological tasks and parent reports of executive functions (EFs) may not be sensitive enough to differentiate VP/VLBW preschoolers with and without ADHD, or these children's EFs are already so impaired that there is not much room for additional impairments imposed by ADHD.

The purpose was identify an association between meconium microbiome, extra-uterine growth restriction, and head circumference catch-up., Materials and Methods: Prospective study with preterm infants born <33 weeks gestational age (GA), admitted at Neonatal Unit and attending the Follow-Up Preterm Program of a tertiary hospital. Excluded out born infants; presence of congenital malformations or genetic syndromes; congenital infections; HIV-positive mothers; and newborns whose parents or legal guardians did not authorize participation. Approved by the institution's ethics committee. Conducted 16S rRNA sequencing using PGM Ion Torrent meconium samples for microbiota analysis., Results: Included 63 newborns, GA 30±2.3 weeks, mean weight 1375.80±462.6 grams, 68.3% adequate weight for GA at birth. Polynucleobacter (p = 0.0163), Gp1 (p = 0.018), and Prevotella (p = 0.038) appeared in greater abundance in meconium of preterm infants with adequate birth weight for GA. Thirty (47.6%) children reached head circumference catch-up before 6 months CA and 33 (52.4%) after 6 months CA. Salmonella (p<0.001), Flavobacterium (p = 0.026), and Burkholderia (p = 0.026) were found to be more abundant in meconium in the group of newborns who achieved catch-up prior to 6th month CA., Conclusion: Meconium microbiome abundance was related to adequacy of weight for GA. Meconium microbiome differs between children who achieve head circumference catch-up by the 6th month of corrected age or after this period., Competing Interests: The authors have declared that no competing interests exist.

Objective: To evaluate the effect of an oral stimulation program in preterm on the performance in the first oral feeding, oral feeding skills and transition time from tube to total oral intake., Study Designer: Double-blind randomized clinical trial including very preterm newborns. Congenital malformations, intracranial hemorrhage grade III or IV, bronchopulmonary dysplasia, and necrotizing enterocolitis were excluded. Intervention group (GI) received an oral stimulation program of tactile extra-, peri-, and intraoral tactile manipulation once a day for 15 minutes, during a 10-day period. Control group (GII) received sham procedure with same duration of time. Feeding ability was assessed by a speech-language pathologist blinded to group assignment. The classification of infants' oral performance was determined by Oral Feeding Skills (OFS). Neonates were monitored until hospital discharge., Results: Seventy-four (37 in each group) were randomized. Mean gestational ages and birth weights were 30±1.4 and 30±1.5 weeks, and 1,452±330g and 1,457±353g for intervention and control groups, respectively. Infants in the intervention group had significantly better rates than infants in the control group on: mean proficiency (PRO) (41.5%±18.3 vs. 19.9%±11.6 (p<0.001)), transfer rate (RT) (2.3 mL/min and 1.1 mL/min (p<0.001)) and overall transfer (OT) (57.2%±19.7 and 35.0%±15.7 (p<0.001)). Median transition time from tube to oral feeding was 4 (3-11) and 8 (7-13) days in intervention and control groups, respectively (p = 0.003). Intake of breast milk was found to reduce transition time from tube feeds to exclusive oral feeding (p<0.001, HR 1.01, 95%CI 1.005-1.019), but the impact of the study intervention remained significant (p = 0.007, HR 1.97, 95%CI 1.2-3.2)., Conclusion: Infants who were breast-fed and an oral stimulation program proved beneficial in reducing transition time from tube feeding to oral feeding., Trial Registration: ClinicalTrials.gov number NCT03025815., Competing Interests: The authors have declared that no competing interests exist.

Objective: This study aimed to describe the experience with a protocol of therapeutic hypothermia (TH) in southern Brazil., Study Design: Newborns with gestational age > 35 weeks with evidence of perinatal asphyxia plus moderate or severe encephalopathy were recruited between March 2011 and November 2017. Whole-body hypothermia for 72 hours, starting within the first 6 hours of life was used. Survivors underwent magnetic resonance imaging (MRI) and electroencephalogram (EEG). The primary outcome was death during hospitalization and neurodevelopment assessed using the Bayley Scales of Infant Development III (BSID III) at 12 months of age., Results: A total of 72 newborns were treated (41 with moderate encephalopathy and 31 with severe encephalopathy), of whom 16 died. MRI was performed in 56 patients, and 24 presented some alterations. Fifty-three patients had an EEG: 11 normal, 20 mildly altered, 12 moderately altered, and 10 severely altered. Forty patients were evaluated through BSID III: 45% presented with some delay in neurodevelopment, 8 (20%) had motor retardation, 15 (37.5%) had language delay, and 13 (32.5%) had a delay in cognitive development., Conclusion: Mortality and adverse events were similar to those described in large randomized controlled trials. TH is a safe and an effective method of neurologic protection in asphyxiated newborns in a developing country when performed adequately., Competing Interests: None declared., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Introduction: Suicide is an issue of great severity in public health worldwide. This study aimed to investigate which instruments are most frequently used by healthcare professionals to assess suicide risk and how accessible such instruments are, as well as to determine the scope of suicide phenomena., Method: A systematic review was performed using the following Boolean searches: "scale AND suicide," "evaluation AND suicide," "questionnaire AND suicide." The articles retrieved were read and selected by two independent researchers - any discrepancies were addressed by a third researcher., Results: From a total number of 206 articles, 20 instruments were identified as being currently used to assess suicide risk. The two most common were the Beck Scale for Suicide Ideation (BSI) and The Columbia - Suicide Severity Rating Scale (C-SSRS)., Conclusion: Even though the two scales (BSI and C-SSRS) are the most frequently mentioned and used by healthcare professionals to assess suicide risk, both instruments present breaches in their structure and there is not yet a single instrument considered to be the gold standard. As a future perspective, there is the urgency of developing a new tool that can widely and completely assess all psychopathological aspects of suicidality.

Objectives: To present current evidence on the etiology, risk factors, diagnosis, and management of early and late neonatal sepsis., Source of Data: Non-systematic review of the Medline (PubMed), Scopus, Web of Science, Cochrane, and Google Scholar databases regarding the following terms: neonatal sepsis, early neonatal sepsis, late neonatal sepsis, empirical antibiotic therapy, sepsis calculator, vancomycin, newborn, preterm newborn., Data Synthesis: Neonatal sepsis is a frequent cause of neonatal morbidity and mortality. Its diagnosis is difficult. Continuous observation of the patient is critical to diagnostic suspicion. When neonatal sepsis is suspected, bacteriological tests should be collected. Vancomycin should not be routinely using in the empirical antibiotic regimen in late neonatal sepsis, and the main protective mechanisms against neonatal sepsis are handwashing and the use of breast milk., Conclusions: Newborns constitute a group that is more vulnerable to sepsis. Knowledge of risk factors and etiological agents allows a better approach to the newborn with sepsis., (Copyright © 2019 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda.

Preterm birth remains the main contributor to early childhood mortality. The vaginal environment, including microbiota composition, might contribute to the risk of preterm delivery. Alterations in the vaginal microbial community structure might represent a risk factor for preterm birth. Here, we aimed to (a) investigate the association between preterm birth and the vaginal microbial community and (b) identify microbial biomarkers for risk of preterm birth. Microbial DNA was isolated from vaginal swabs in a cohort of 69 women enrolled at hospital admission for their delivery. Microbiota was analyzed by high-throughput 16S rRNA sequencing. While no differences in microbial diversity measures appeared associated with the spontaneous preterm and full-term outcomes, the microbial composition was distinct for these groups. Differential abundance analysis showed Lactobacillus species to be associated with full-term birth whereas an unknown Prevotella species was more abundant in the spontaneous preterm group. Although we studied a very miscegenated population from Brazil, our findings were similar to evidence pointed by other studies in different countries. The role of Lactobacillus species as a protector in the vaginal microbiome is demonstrated to be also a protector of spontaneous preterm outcome whereas the presence of pathogenic species, such as Prevotella spp., is endorsed as a factor of risk for spontaneous preterm delivery.

Purpose: To identify the most effective dressing for covering long-term central venous catheter exit site to prevent catheter-related infections and skin irritation in patients undergoing hematopoietic stem cell transplantation., Methods: Systematic Review. The search was performed in the following electronic databases: CINAHL, Cochrane Library CENTRAL, EMBASE, LILACS, PubMed, Scopus, and Web of Science. Google Scholar was used for the gray literature search., Results: Seven studies were included which tested different arrangements of dressings: sterilized gauze and adhesive tape with a transparent polyurethane film (n = 2), transparent polyurethane film with a different replacement interval frequency (n = 2), transparent polyurethane film with and without chlorhexidine released continuously by the dressing at the site of intravascular catheter insertion (n = 2), and dressings vs. no dressings (n = 1). The meta-analysis for catheter-related infection prevention showed no difference between type of dressing (RR 1.76, [95% CI 0.82; 3.75], I 2 0%) and for the replacement frequency at different intervals (RR 1.04, [95% CI 0.67; 1.61], I 2 0%). The meta-analysis for skin irritation evaluated the transparent polyurethane film replacement frequency and indicated that a longer dressing replacement interval (10 to 15 days) reduces the risk of developing this outcome (RR 0.71, 0.52; 0.96, 95% CI, I 2 24%)., Conclusions: Regarding the type of the dressing, there is no evidence indicating the best dressing. Although there is no evidence available for the ideal replacement frequency, the risk to develop skin irritation is reduced in longer dressing replacements intervals.

Introduction: Macrolides have anti-inflammatory and immunomodulatory properties that give this class of antibiotics a role that differs from its classical use as an antibiotic, which opens new therapeutic possibilities., Objective: The aim of this study was to evaluate the anti-inflammatory effect of azithromycin in preventing mechanical ventilation (MV)-induced lung injury in very-low-birth-weight preterm neonates., Methods: This is a randomized, double-blind, placebo-controlled trial of preterm neonates who received invasive MV within 72 h of birth. Patients were randomized to receive intravenous azithromycin (at a dose of 10/mg/kg/day for 5 days) or placebo (0.9% saline) within 12 h of the start of MV. Two blood samples were collected (before and after intervention) for measurement of interleukins (ILs) and PCR for Ureaplasma. Patients were followed up throughout the hospital stay for the outcomes of death and broncho-pulmonary dysplasia defined as need for oxygen for a period of ≥28 days of life (registered at ClinicalTrials.gov, No. NCT03485703)., Results: Forty patients were analyzed in the azithromycin group and 40 in the placebo group. Five days after the last dose, serum IL-2 and IL-8 levels dropped significantly in the azithromycin group. There was a significant reduction in the incidence of death and O2 dependency at 28 days/death in azithromycin-treated patients regardless of the detection of Ureaplasma in blood., Conclusions: Azithromycin has anti-inflammatory effects, with a decrease in cytokines after 5 days of use and a reduction in death and O2 dependency at 28 days/death in mechanically ventilated preterm neonates., (© 2020 S.
