RESUMO
BACKGROUND AND OBJECTIVES: The Brazilian Neonatal Resuscitation Program releases guidelines based on local interpretation of international consensus on science and treatment recommendations. We aimed to analyze whether guidelines for preterm newborns were applied to practice in the 20 Brazilian Network on Neonatal Research centers of this middle-income country. METHODS: Prospectively collected data from 2014 to 2020 were analyzed for 8514 infants born at 230/7 to 316/7 weeks' gestation. The frequency of procedures was evaluated by gestational age (GA) category, including use of a thermal care bundle, positive pressure ventilation (PPV), PPV with a T-piece resuscitator, maximum fraction of inspired oxygen (Fio2) concentration during PPV, tracheal intubation, chest compressions and medications, and use of continuous positive airway pressure in the delivery room. Logistic regression, adjusted by center and year, was used to estimate the probability of receiving recommended treatment. RESULTS: For 3644 infants 23 to 27 weeks' GA and 4870 infants 28 to 31 weeks' GA, respectively, the probability of receiving care consistent with guidelines per year increased, including thermal care (odds ratio [OR], 1.52 [95% confidence interval (CI) 1.44-1.61] and 1.45 [1.38-1.52]) and PPV with a T-piece (OR, 1.45 [95% CI 1.37-1.55] and 1.41 [1.32-1.51]). The probability of receiving PPV with Fio2 1.00 decreased equally in both GA groups (OR, 0.89; 95% CI, 0.86-0.93). CONCLUSIONS: Between 2014 and 2020, the resuscitation guidelines for newborns <32 weeks' GA on thermal care, PPV with a T-piece resuscitator, and decreased use of Fio2 1.00 were translated into clinical practice.

OBJECTIVES: To conduct the Brazilian translation, cross-cultural adaptation, validation, and reliability testing of the EMpowerment of PArents in THe Intensive Care (EMPATHIC-30). DESIGN: Prospective study. SETTING: PICU of a tertiary-care teaching hospital. PATIENTS: Parents (n = 141) completed the translated EMPATHIC-30 questionnaire 72 hours after their child's PICU discharge. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The translation and cultural adaptation were performed in accordance with the principles of good practice for the translation and cultural adaptation process for patient-reported outcomes measures. Sentences were adapted according to the Brazilian syntax. Total content validity coefficient was above the established average (> 0.8). Reliability was evaluated with the coefficients McDonald omega and Cronbach alpha. The lowest Cronbach alpha found was 0.47 (CI 95%, 0.35-0.59) in the organization domain, where the lowest response rate was also concentrated. The values of the other domains were as follows: 0.64 (95% CI, 0.55-0.73) for information, 0.77 (95% CI, 0.71-0.83) for care and treatment, 0.72 (95% CI, 0.66-0.78) for parent participation, and 0.72 (95% CI, 0.65-0.79) for professional attitudes. The total internal consistency independent of the domain was 0.90 (CI 95%, 0.88-0.92). With regard to McDonald Omega, values were identified: 0.68 (95% CI, 0.49-0.88) for information, 0.73 (95% CI, 0.61-0.85) for care and treatment, 0.85 (95% CI, 0.47-0.80) for parent participation, 0.85 (95% CI, 0.76-0.93), and 0.72 (95% CI, 0.58-0.86) for professional attitudes. CONCLUSIONS: EMPATHIC-30 has been translated and culturally adapted for the Brazilian population. Validation demonstrated an above-average total content validity coefficient, confirming the instrument content validity. A sufficient reliability was observed in both analyzed coefficients. The results support the use of the Brazilian version of EMPATHIC-30 for the evaluation of parents' satisfaction of children admitted to the PICU.

Abstract Objective: To assess the prevalence, mortality and risk factors associated with the birth of very low birth weight preterm infants over a period of 33 years. Methods: Four cross-sectional studies were analyzed, using data from perinatal interviews of birth cohorts in the city of Pelotas collected in 1982, 1993, 2004, and 2015. Based on perinatal questionnaires, anthropometric measurements of newborns and death certificates were analyzed to obtain the prevalence rate, neonatal mortality, and risk factors (maternal age, income and type of delivery) for very low birth weight. Results: A total of 19,625 newborns were included in the study. In the years 1982, 1993, 2004, and 2015, there were, respectively, 5909, 5232, 4226, and 4258 births. The prevalence of very low birth weight was, respectively, 1.1% (n = 64), 0.9% (n = 46), 1.4% (n = 61), and 1.3% (n = 54). There was no statistical evidence of an increasing trend over time (p = 0.11). Among the risk factors, family income in the three poorest quintiles was associated with prevalence rates that were approximately twice as high as in the richest quintile (p = 0.003). Mortality per 1000 live births for neonates weighing <1500 g decreased from 688 to 259 per thousand from 1982 to 2015 (p < 0.001), but still represented 61% of neonatal deaths in the latter year. Conclusion: Although mortality in very low birth weight decreased by more than 60% in recent years, this group still contributes with more than half of neonatal deaths. Low family income remains an important risk factor in this scenario.
Resumo Objetivo: Verificar a prevalência, mortalidade e fatores de risco associados aos nascimentos de prematuros de muito baixo peso ao nascer (MBPN) ao longo de 33 anos. Métodos: Série de quatro estudos transversais com o uso de dados das entrevistas perinatais das coortes de nascimento da cidade de Pelotas coletados em 1982, 1993, 2004 e 2015. A partir de questionários perinatais, medidas antropométricas dos recém-nascidos e certidões de óbito, foram analisadas a prevalência, a mortalidade neonatal e os fatores de risco (idade materna, renda e tipo de parto) para prematuros de muito baixo peso ao nascer. Resultados: Foram incluídos no estudo 19.625 recém-nascidos. Em 1982, 1993, 2004 e 2015 ocorreram, respectivamente, 5.909, 5.232, 4.226 e 4.258 nascimentos. A prevalência de prematuros de muito baixo peso ao nascer naqueles anos foi, respectivamente, de 1,1% (n = 64), 0,9% (n = 46), 1,4% (n = 61) e 1,3% (n = 54). A tendência de aumento durante o período não alcançou significância estatística (p = 0,11). Entre os fatores de risco, a renda familiar nos três quintis mais pobres esteve associada a prevalências cerca de duas vezes mais altas do que no quintil mais rico (p = 0,003). A mortalidade por 1.000 nascidos vivos para os neonatos com peso < 1500 g caiu de 688 para 259 por mil ao longo dos anos (p < 0,001), mas ainda representa 61% dos óbitos neonatais em 2015. Conclusão: Embora a mortalidade nos prematuros de muito baixo peso ao nascer tenha diminuído em mais de 60% nos últimos anos, esse grupo ainda contribui com mais da metade dos óbitos neonatais. A baixa renda familiar continua a ser fator de risco importante nesse cenário.

OBJECTIVES: To evaluate serum ferritin measured within 48 hours of admission as a prognostic marker and examine the association with unfavorable outcomes in a population of pediatric patients with sepsis and high prevalence of iron deficiency anemia in which this biomarker is routinely measured. DESIGN: Retrospective cohort study. SETTING: PICU of a tertiary care teaching hospital in a middle-income country in South America. PATIENTS: All patients 6 months to 18 years old (n = 350) admitted with a diagnosis of sepsis, suspected or proven, were eligible for inclusion. Exclusion criteria were length of PICU stay less than 8 hours and inherited or acquired disorder of iron metabolism that could interfere with serum ferritin levels. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Three-hundred twelve patients had their ferritin levels measured within 48 hours, and only 38 did not. The prevalence of iron deficiency anemia (hemoglobin < 11 g/dL and mean corpuscular volume < 80 fl was 40.3%. The median of the highest serum ferritin level within 48 hours was 150.5 ng/mL (interquartile range, 82.25-362 ng/mL), being associated with mortality (p < 0.001; Exp(B), 5.170; 95% CI, 2.619-10.205). A 10-fold increase in ferritin level was associated with a five-fold increase in mortality. There was a monotonic increase in mortality with increasing ferritin levels (p < 0.05). Regarding the discriminatory power of ferritin for mortality, the area under the receiver operating characteristic curve was 0.787 (95% CI, 0.737-0.83; p < 0.0001). CONCLUSIONS: Serum ferritin at lower thresholds predicts mortality in children with sepsis admitted to the ICU in a middle-income country with high prevalence of iron deficiency anemia.

OBJECTIVE: To verify the association between prone position, increased diuresis, and decreased cumulative fluid balance in critically ill pediatric patients who underwent mechanical ventilation (MV) for pulmonary causes and describe adverse events related to the use of the position. METHODS: This is a retrospective observational study. Patients aged between 1 month and 12 years who underwent MV for pulmonary causes, between January 2013 and December 2015, were selected and divided between those who were put on prone position (PG) and those who were not (CG) during the hospitalization at the Pediatric Intensive Care Unit (PICU). Data were analyzed longitudinally from D1 to D4. RESULTS: A total of 77 patients (PG = 37 and CG = 40) were analyzed. The general characteristics of both groups were similar. In the comparison between the groups, there was no increase in diuresis or decrease in cumulative fluid balance in the prone group. In the longitudinal analysis of D1 to D4, we saw that the PG presented higher diuresis (p = 0.034) and a lower cumulative fluid balance (p = 0.001) in D2. Regarding the use of diuretics, there was greater use of furosemide (P <0.001) and spironolactone (P = 0.04) in the PG. There was no increase in adverse events during the use of the prone position. CONCLUSION: The prone position was not associated with increased diuresis or decreased cumulative fluid balance in critically ill pediatric patients who underwent to MV for pulmonary causes.

RESUMO OBJETIVO: Verificar a associação entre posição prona, aumento da diurese e diminuição do balanço hídrico em pacientes pediátricos criticamente enfermos e submetidos à ventilação mecânica (VM) por causa pulmonar, além de descrever eventuais intercorrências relacionadas à aplicação dessa posição. MÉTODOS: Estudo observacional retrospectivo. Pacientes submetidos à VM por causa pulmonar, com idade entre 1 mês e 12 anos no período entre janeiro de 2013 e dezembro de 2015, foram selecionados e divididos entre os que receberam posição prona (GP) e os que não receberam (GC) durante a internação na Unidade de Terapia Intensiva Pediátrica (Utip). Os dados foram analisados longitudinalmente de D1 a D4. RESULTADOS: Foram analisados77 pacientes (GP=37 e GC=40). Em termos de características gerais, os grupos foram semelhantes entre si. Na comparação entre os grupos, não houve aumento da diurese ou diminuição do balanço hídrico cumulativo no grupo prona. Na análise longitudinal de D1 a D4, evidenciou-se que o GP apresentou maior diurese (p=0,034) e menor balanço hídrico cumulativo (p = 0,001) no D2. Com relação ao uso de diuréticos, houve maior uso de furosemida (P<0,001) e de espironolactona (P=0,04) no GP. Não houve aumento de eventos adversos durante a utilização da posição prona. CONCLUSÃO: A posição prona não demonstrou associação com aumento da diurese ou diminuição de balanço hídrico cumulativo em pacientes críticos pediátricos submetidos à VM por causa pulmonar.

This prospective cohort study aimed to assess the association of admission hypothermia (AH) with death and/or major neonatal morbidities among very low birth weight (VLBW) preterm infants based on the relative performance of 20 centers of the Brazilian Network of Neonatal Research. This is a retrospective analysis of prospectively collected data using the database registry of the Brazilian Network on Neonatal Research. Center performance was defined by the relative mortality rate using conditional inference trees. A total of 4356 inborn singleton VLBW preterm infants born between January 2013 and December 2016 without malformations were included in this study. The centers were divided into two groups: G1 (with lower mortality rate) and G2 (with higher mortality rate). Crude and adjusted relative risks (RR) and 95% confidence intervals (95%CI) were estimated by simple and multiple log-binomial regression models. An AH rate of 53.7% (19.8-93.3%) was significantly associated with early neonatal death in G1 (adjusted RR 1.41, 95% CI 1.09-1.84) and G2 (adjusted RR 1.29, 95%CI 1.01-1.65) and with in-hospital death in G1 (adjusted RR 1.29, 95%CI 1.07-1.58). AH was significantly associated with a lower frequency of necrotizing enterocolitis (adjusted RR 0.58, 95%CI 38-0.88) in G2.Conclusion: AH significantly associated with early neonatal death regardless of the hospital performance. In G2, an unexpected protective association between AH and necrotizing enterocolitis was found, whereas the other morbidities assessed were not significantly associated with AH. What is Known: ⢠Admission hypothermia is associated with early neonatal death. ⢠The association of admission hypothermia with major neonatal morbidities has not been fully established. What is New: ⢠Admission hypothermia was significantly associated with early neonatal and in-hospital death in centers with the lowest relative mortality rates. ⢠Admission hypothermia was not associated with major neonatal morbidities and with in-hospital death but was found to be a protective factor against necrotizing colitis in centers with the highest relative mortality rates.

Abstract Objective: The aim of this study was to verify the association of echocardiogram, ferritin, C-reactive protein, and leukocyte count with unfavorable outcomes in pediatric sepsis. Methods: A prospective cohort study was carried out from March to December 2014, with pediatric critical care patients aged between 28 days and 18 years. Inclusion criteria were diagnosis of sepsis, need for mechanical ventilation for more than 48 h, and vasoactive drugs. Serum levels of C-reactive protein, ferritin, and leukocyte count were collected on the first day (D0), 24 h (D1), and 72 h (D3) after recruitment. Patients underwent transthoracic echocardiography to determine the ejection fraction of the left ventricle on D1 and D3. The outcomes measured were length of hospital stay and in the pediatric intensive care unit, mechanical ventilation duration, free hours of VM, duration of use of inotropic agents, maximum inotropic score, and mortality. Results: Twenty patients completed the study. Patients with elevated ferritin levels on D0 had also fewer ventilator-free hours (p = 0.046) and higher maximum inotropic score (p = 0.009). Patients with cardiac dysfunction by echocardiogram on D1 had longer hospital stay (p = 0.047), pediatric intensive care unit stay (p = 0.020), duration of mechanical ventilation (p = 0.011), maximum inotropic score (p = 0.001), and fewer ventilator-free hours (p = 0.020). Conclusion: Cardiac dysfunction by echocardiography and serum ferritin value was significantly associated with unfavorable outcomes in pediatric patients with sepsis.
Resumo Objetivo: Verificar a associação do ecocardiograma, da ferritina, da proteína C reativa (PCR) e da contagem de leucócitos com desfechos desfavoráveis na sepse pediátrica. Métodos: Estudo de coorte prospectivo, de março a dezembro de 2014, com pacientes críticos pediátricos entre 28 dias e 18 anos. Critérios de inclusão foram diagnóstico de sepse, necessidade de ventilação mecânica (VM) por mais de 48 horas e uso de drogas vasoativas. Avaliaram‐se os níveis séricos PCR, ferritina, contagem de leucócitos, no recrutamento (D0), 24 horas (D1) e 72 horas (D3) após o recrutamento. No D1 e no D3 todos os pacientes foram submetidos a ecocardiograma transtorácico para determinação da Fração de Ejeção (FE) do ventrículo esquerdo. Os desfechos avaliados foram tempo de internação hospitalar e na Unidade de Terapia Intensiva Pediátrica (UTIP); duração da VM; horas livres de VM; duração do uso de inotrópicos; escore de inotrópicos máximo e mortalidade. Resultados: Vinte pacientes completaram o estudo. Ferritina elevada no D0 associou‐se com menor tempo livre de ventilação (p = 0,046) e maior escore de inotrópicos máximo (p = 0,009). A disfunção cardíaca pelo ecocardiograma no D1 relacionou‐se com maior tempo de internação hospitalar (p = 0,047), de UTIP (p = 0,020), VM total (p = 0,011), escore de inotrópicos máximo (p = 0,001) e menor tempo livre de VM (p = 0,020). Conclusão: A disfunção cardíaca pelo ecocardiograma e o valor de ferritina sérica associaram‐se significativamente com desfechos desfavoráveis nos pacientes pediátricos com sepse.
