RESUMO
OBJECTIVE: To evaluate the temporal trend of bronchopulmonary dysplasia (BPD) in preterm infants who survived to at least 36 weeks' post-menstrual age (PMA) and BPD or death at 36 weeks' PMA, and to analyse variables associated with both outcomes. DESIGN: Retrospective cohort with data retrieved from an ongoing national registry. SETTING: 19 Brazilian university public hospitals. PATIENTS: Infants born between 2010 and 2019 with 23-31 weeks and birth weight 400-1499 g. MAIN OUTCOME MEASURES: Temporal trend was evaluated by Prais-Winsten model and variables associated with BPD in survivors or BPD or death were analysed by logistic regression. RESULTS: Of the 11 128 included infants, BPD in survivors occurred in 22%, being constant over time (annual per cent change (APC): -0.80%; 95% CI: -2.59%; 1.03%) and BPD or death in 45%, decreasing over time (APC: -1.05%; 95% CI: -1.67%; -0.43%). Being male, small for gestational age, presenting with respiratory distress syndrome, air leaks, needing longer duration of mechanical ventilation, presenting with treated patent ductus arteriosus and late-onset sepsis were associated with an increase in the chance of BPD. For the outcome BPD or death, maternal bleeding, multiple gestation, 5-minute Apgar <7, late-onset sepsis, necrotising enterocolitis and intraventricular haemorrhage were added to the variables reported above as increasing the chance of the outcome. CONCLUSION: The frequency of BPD in survivors was constant and BPD or death decreased by 1.05% at each study year. These results show some improvement in perinatal care in Brazilian units which resulted in a reduction of BPD or death, but further improvements are still needed to reduce BPD in survivors.
RESUMO
Abstract 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-21st (IG21). Methods: 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 < 3rd (SGA3) or 10th (SGA10) percentiles of BW, and large-for-gestational-age (LGA) as being > 97th percentile of BW. Stunting as being < 3rd percentile of the length and wasting as being < 3rd 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.
RESUMO
Abstract Objective Assess the mediating role of breastfeeding self-efficacy in the association between the Kangaroo Neonatal Intermediate Care Unit and exclusive breastfeeding. Method Cross-sectional study nested in a cohort, carried out in the Neonatal Unit of a Brazilian university hospital between September 2018 and March 2020. The sample consisted of 114 newborns weighing ≤1800 g and their mothers who were divided into those who participated in the first and second stages of the Kangaroo Method and those who only passed through the first stage, categorized as the Conventional group. To assess the self-efficacy of breastfeeding, the Breastfeeding Self Efficacy Scale - Short-Form was used. The Mann-Whitney test was used to compare the breastfeeding self-efficacy score between the groups, and Fisher's exact test to compare rates of exclusive breastfeeding. The adjusted structural equation model was used to check for the mediating effect of breastfeeding self-efficacy. The significance level adopted was 5%. Results The kangaroo group had a higher rate of exclusive breastfeeding at hospital discharge (p= 0.000). There was a positive association between having remained in the kangaroo (p= 0.003) and the breastfeeding self-efficacy score (p= 0.025) with the rate of exclusive breastfeeding at hospital discharge. Breastfeeding self-efficacy did not act as a mediator. Conclusion The self-efficacy of breastfeeding and the stay of the low birth weight newborn baby in the kangaroo unit acted positively and independently in exclusive breastfeeding, and the self-efficacy of breastfeeding did not act as a mediator in this association.
RESUMO
ABSTRACT Objective: To assess the prevalence of hypothermia in the delivery room, at admission, and 2 to 3 hours after admission in the neonatal intensive care unit (NICU), factors associated and possible relationship with morbidity and mortality in preterm infants with very low birth weight (VLBW). Methods: Cross-sectional study with data collection based on a retrospective review of medical records and including infants born in 2016 and 2017, with birth weights <1500g, and gestational ages <34 weeks. Data about VLBW preterm infants, maternal data and temperature in the delivery room were analyzed. Hypothermia was considered when axillary temperature <36°C. For statistical analysis, the chi-square test or G test, canonical and Spearman correlation, and logistic regression were used. Results: 149 newborns (NB) were included in the study. The prevalence of hypothermia in delivery room, at admission to the NICU and 2 to 3 hours after admission was 25.8%, 41.5% and 40.2%, respectively. The temperature of NBs was directly proportional to gestational age (p<0.010), birth weight (p<0.010), and Apgar score (p<0.050). There was an inverse association with hypothermia in the delivery room and cesarean delivery (OR 0.25; p=0.016). Conclusions: Hypothermia was a prevalent problem in the studied population. The neonatal temperature was directly proportional to gestational age, birth weight and Apgar score. Hypothermia was associated with maternal factors, such as cesarean delivery. It is necessary to implement and improve strategies for its prevention.
RESUMO Objetivo: Avaliar a prevalência da hipotermia na sala de parto, à admissão e 2 a 3 horas após a admissão na Unidade de Terapia Intensiva Neonatal (UTIN), fatores associados e possível associação com morbimortalidade em recém-nascidos pré-termo de muito baixo peso (RNPT MBP). Métodos: Estudo transversal, com coleta retrospectiva de dados em prontuários dos RNPT MBP nascidos em 2016 e 2017, com peso <1500g e idade gestacional <34 semanas. Foram analisados dados dos RNPT MBP, da mãe e a temperatura na sala de parto. Foi considerada hipotermia a temperatura axilar <36°C. Para análise estatística, foram utilizados teste do qui-quadrado ou teste G, correlacçã canônica e de Spearman, e regressaã logística. Resultados: Fizeram parte do estudo 149 recém-nascidos (RN). A prevalência da hipotermia na sala de parto, à admissão na UTIN e 2 a 3 horas após a admissão, foi de 25,8, 41,5 e 40,2%, respectivamente. A temperatura do RN foi diretamente proporcional à idade gestacional (p<0,010), ao peso ao nascimento (p<0,010) e ao índice de Apgar (p<0,050). Observou-se associação inversa entre hipotermia na sala de parto e parto cesáreo (OR 0,25; p=0,016). Conclusões: A hipotermia foi um problema prevalente na população estudada. A temperatura do RN foi diretamente proporcional à idade gestacional, peso ao nascimento e Boletim de Apgar. Esteve também associada a fatores maternos, como parto cesáreo. Portanto, faz-se necessário a implementação e aprimoramento de estratégias para a sua prevenção.
RESUMO
ABSTRACT Objectives: to analyze the occurrence of respiratory complications over the first year of life in preterm infants who did not receive palivizumab monoclonal antibodies. Methods: analytical retrospective cohort study with preterm infants born between 2012 and 2016 in Uberlândia, state of Minas Gerais, Brazil. Data collection occurred from January to November 2018, by consulting hospital and primary healthcare medical records. Data were processed with the Poisson regression model, with p<0.05. Results: of a total of 5,213 preterm births, 504 (9.7%) met the inclusion criteria. The preterm infants in this subset were assisted 2,899 times in primary care, which resulted in 1,098 (37.5%) medical diagnoses, of which 803 (78.5%) involved the respiratory tract. Preterm babies fed on formula milk at hospital discharge had more diagnoses of respiratory diseases. Maternal age (p=0.039), respiratory diagnosis at hospital discharge (p=0.028), and number of sporadic appointments (p<0.001) showed a significant association with bronchiolitis; number of sporadic appointments showed a significant association with occurrence of respiratory diseases; and breastfeeding had a protective effect against the development of bronchiolitis. Conclusions: preterm infants who did not receive palivizumab showed a high percentage of respiratory diseases, and breastfeeding helped protect them against bronchiolitis. It is recommended that these preterm babies be monitored in primary health care.

RESUMO
OBJECTIVES: To evaluate the impact of invasive mechanical ventilation associated with two serum inflammatory cytokines and clinical indicators, on the second day of life, as predictors of bronchopulmonary dysplasia in very low birth weight preterm infants. It was hypothesized that the use of invasive mechanical ventilation in the first hours of life is associated with biomarkers that may predict the chances of preterm infants to develop bronchopulmonary dysplasia. METHODS: Prospective cohort of 40 preterm infants with gestational age <34 weeks and birth weight <1500â¯g. The following were analyzed: clinical variables; types of ventilator support used (there is a higher occurrence of bronchopulmonary dysplasia when oxygen supplementation is performed by long periods of invasive mechanical ventilation); hospitalization time; quantification of two cytokines (granulocyte and macrophage colony stimulating factor [GM-CSF] and eotaxin) in blood between 36 and 48â¯h of life. The preterm infants were divided in two groups: with and without bronchopulmonary dysplasia. RESULTS: The GM-CSF levels presented a significantly higher value in the bronchopulmonary dysplasia group (pâ¯=â¯0.002), while eotaxin presented higher levels in the group without bronchopulmonary dysplasia (pâ¯=â¯0.02). The use of continuous invasive mechanical ventilation was associated with increased ratios between GM-CSF and eotaxin (100% sensitivity and 80% specificity; receiver operating characteristic areaâ¯=â¯0.9013, CIâ¯=â¯0.7791-1.024, pâ¯<â¯0.0001). CONCLUSIONS: The duration of invasive mechanical ventilation performed in the first 48â¯h of life in the very low birth weight infants is a significant clinical predictor of bronchopulmonary dysplasia. The use of continuous invasive mechanical ventilation was associated with increased ratios between GM-CSF and eotaxin, suggesting increased lung injury and consequent progression of the disease.

OBJECTIVE: To verify whether the use of the T-piece resuscitator compared with the self-inflating bag in preterm infants ventilated at birth modifies survival to hospital discharge without major morbidities. DESIGN: Pragmatic prospective cohort study. SETTING: 20 Brazilian university hospitals of Brazilian Network on Neonatal Research. Patients were 1962 inborn infants in 2014-2015 ventilated at birth with 23-33' weeks gestation and birth weight 400-1499 g without malformations. Patients transferred until the 27th day after birth were excluded. INTERVENTIONS: Positive pressure ventilation at birth with T-piece resuscitator or self-inflating bag without positive end expiratory pressure valve. Intervention with ventilation followed the Brazilian Society of Pediatrics guidelines. The choice of the equipment was at the neonatologist's discretion in each delivery. The main outcome measures were survival to hospital discharge without bronchopulmonary dysplasia, severe peri-intraventricular haemorrhage and periventricular leucomalacia. Logistic regression adjusted for confounding variables was applied for main outcome. RESULTS: 1456 (74%) were only ventilated with T-piece resuscitator and 506 (26%) with the self-inflating bag. The characteristics of those ventilated with T-Piece resuscitator versus self-inflating bag were birth weight 969 ± 277 vs 941 ± 279 g, gestational age 28.2±2.5 vs 27.8±2.7 weeks and survival to hospital discharge without major morbidities 47% vs 35%. Logistic regression adjusted for maternal characteristics, obstetric and neonatal morbidities showed that the T-piece resuscitator increased the chance of survival to hospital discharge without major morbidities (OR=1.38; 95% CI 1.06 to 1.80; Hosmer-Lemeshow goodness of fit: 0.695). CONCLUSION: This study is the first that highlights the effectiveness of T-piece resuscitator ventilation in improving relevant outcomes in preterm neonates.

Abstract Pediatric patients, especially those admitted to the neonatal intensive care unit (ICU), are highly vulnerable to medication errors. This study aimed to measure the prescription error rate in a university hospital neonatal ICU and to identify susceptible patients, types of errors, and the medicines involved. The variables related to medicines prescribed were compared to the Neofax prescription protocol. The study enrolled 150 newborns and analyzed 489 prescription order forms, with 1,491 medication items, corresponding to 46 drugs. Prescription error rate was 43.5%. Errors were found in dosage, intervals, diluents, and infusion time, distributed across 7 therapeutic classes. Errors were more frequent in preterm newborns. Diluent and dosing were the most frequent sources of errors. The therapeutic classes most involved in errors were antimicrobial agents and drugs that act on the nervous and cardiovascular systems.

Objetivos: conhecer as indicações do uso de NOi, dose média utilizada e resposta ao tratamento em recém-nascidos internados em Unidade de Terapia Intensiva Neonatal. Métodos: foram analisados 62 prontuários e considerados dois grupos de recém-nascidos (RN) de acordo com o desfecho para sobrevida (n=39) ou óbito (n=23). Testes t-Student e binomial, p<0,05. Resultados: do total, 47 eram masculinos, 18 nasceram de parto normal e 44 de cesariana. Os RNs que sobreviveram tinham maior idade gestacional clínica e mais peso ao nascimento (p<0,05). Cardiopatia congênita, hipoplasia pulmonar, sepse e síndrome da membrana hialina (SMH) foram mais frequentes nos RNs que evoluíram para óbito, enquanto que a síndrome de aspiração de mecônio (SAM)estava mais presente nos RNs que sobreviveram (p<0,05). Não houve diferença significativa quanto a: asfixia perinatal, hérnia diafragmática, hipertensão pulmonar persistente neonatal (HPPN) e taquipneia transitória do recém-nascido (p>0,05). A dose inicial de NOi e a duração do tratamento foram maiores nos RNs que sobreviveram (p<0,05). A idade de início do tratamento, a dose máxima de NOi e o tempo de ventilação mecânica não apresentaram diferenças entre os grupos (p>0,05). O índice de oxigenação foi significativamente mais alto nos óbitos (p<0,05). Não foram observados efeitos colaterais. Conclusões: a terapia com NOi foi indicada principalmente na asfixia perinatal, SAM, SMH e sepse. As doses de NOi entre 15 e 30 ppm mostraram-se seguras e a diminuiçãodo índice de oxigenação sugere resposta positiva ao tratamento.
Objectives: To know the inhaled nitric oxide (iNO) use indications, the average used dose, and the reaction to treatment in newborns hospitalized at the Neonatal Intensive Care Unit. Methods: 62 medical records were analyzed and two newborn groups were considered according to the survival (n=39) or death (n=23) outcome. t-Student and binomial tests, p<0.05. Results: From the total, 47 subjects were male, 18 were born from natural childbirth, and 44 from cesarean section. The newborns that survived had a higher clinical gestational age and more weight at birth (p>0.05). Congenital heart defect, pulmonary hipoplasia, sepsis, and hyaline membrane syndrome (HMS) were more frequent in newborns that evolved to death, while the meconium aspiration syndrome (MAS) was more present in the ones that survived (p<0.05). There was no significant difference concerning: perinatal asphyxia, diaphragmatichernia, neonatal persistent pulmonary hypertension (NPPH), and newborn transient taquipneia (p>0.05). The iNO initial dose and treatment time were superior in newborns that survived (p<0.05). Age in the beginning of the treatment, maximum doses of iNO, and time of mechanical ventilation did not present significant differences between the groups (p>0.05).The oxygenation index was significantly higher in the deceased ones (p<0.05). No adverse effects were seen. Conclusions: Therapy with iNO was mainly indicated for perinatal asphyxia, MAS, HMS, and sepsis. iNO doses between 15 and 30 ppm proved to be safe, and the decrease of the oxygenation index suggests a positive reaction to the treatment.

In this study, IgA1 levels in the milk and serum of puerperae were compared and a correlation was established between the levels of this immunoglobulin and the occurrence of parasitism. Eighty-three paired milk and serum samples were obtained from puerperal and IgA1 levels were analyzed. In addition, the presence of intestinal parasites in stool samples from these puerperae was determined. Twelve puerperae tested positive for intestinal parasites and all their samples presented an IgA1 ELISA Index > 1. There was a correlation between serum and milk IgA1 levels and puerperae with any parasite in their stool (r = 0.6723; p = 0.0166). This finding may reinforce the importance of breast-feeding for the protection of neonates.
