RESUMO
OBJECTIVE: Scientific scrutiny has proved the safety and benefits of caffeine to treat apnoea of prematurity (AOP). However, there is no consensus on the effects of this treatment on sleep, especially considering the key role of adenosine and early brain development for sleep maturation. We systematically reviewed studies with sleep as a primary and/or secondary outcome or any mention of sleep parameters in the context of caffeine treatment for AOP. METHODS: We performed a systematic search of PubMed, Web of Science and the Virtual Health Library from inception to 7 September 2022 to identify studies investigating the short- and long-term effects of caffeine to treat AOP on sleep parameters. We used the PIC strategy considering preterm infants as the Population, caffeine for apnoea as the Intervention and no or other intervention other than caffeine as the Comparison. We registered the protocol on PROSPERO (CRD42021282536). RESULTS: Of 4019 studies, we deemed 20, including randomised controlled trials and follow-up and observational studies, to be eligible for our systematic review. The analysed sleep parameters, the evaluation phase and the instruments for sleep assessment varied considerably among the studies. The main findings can be summarised as follows: (i) most of the eligible studies in this systematic review indicate that caffeine used to treat AOP seems to have no effect on key sleep parameters and (ii) the effects on sleep when caffeine is administered earlier, at higher doses or for longer periods than the most common protocol have not been investigated. There is a possible correlation between the caffeine concentration and period of exposure and negative sleep quality, but the sleep assessment protocols used in the included studies did not have high-quality standards and could not provide good evidence. CONCLUSIONS AND IMPLICATIONS: Sleep quality is an important determinant of health, and better investments in research with adequate sleep assessment tools are necessary to guarantee the ideal management of children who were born preterm.
RESUMO
Identificar variáveis com potencial de intervenção que estejam associadas ao volume de leite esgotado das mães de recém-nascidos prematuros. Trata-se de um estudo de coorte, descritivo e exploratório. A coleta de dados ocorreu em um hospital materno-infantil do Sul do Brasil no período de julho de 2021 a janeiro de 2022, por meio de entrevistas a 20 mães de recém-nascidos prematuros. Verificou-se que, em relação ao número de vezes ao dia que foi realizado o esgotamento hospitalar e domiciliar, a mediana foi de 4 vezes. A maioria das mães utilizou dois métodos de esgotamento das mamas (manual e com bomba de sucção). O estudo identificou que o volume de leite esgotado foi abaixo do esperado pelo Ministério da Saúde. Destaca-se a falta de procura do banco de leite para o esgotamento, problemas relacionados à mama, como exemplo o método utilizado para esgotamento.
To identify variables with intervention potential that are associated with the volume of depleted milk from mothers of premature newborns. This is a cohort, descriptive, and exploratory study. Data collection occurred in a maternal-infant hospital in southern Brazil from July 2021 to January 2022, through interviews with 20 mothers of premature newborns. It was verified that, in relation to the number of times per day that hospital and home milk expression was performed, the median was 4 times. Most mothers used two methods of breast milk expression (manual and with suction pump). The study found that the volume of expressed milk was lower than expected by the Ministry of Health. We highlight the lack of demand of the milk bank for expression, problems related to the breast, as an example of the method used for expression.
Identificar variables con potencial de intervención que se asocian al volumen de leche agotada de madres de recién nacidos prematuros. Se trata de un estudio de cohortes, descriptivo y exploratorio. La recolección de datos ocurrió en un hospital materno-infantil en el sur de Brasil de julio de 2021 a enero de 2022, a través de entrevistas con 20 madres de recién nacidos prematuros. Se verificó que, en relación al número de veces por día que se realizaba el agotamiento hospitalario y domiciliario, la media fue de 4 veces. La mayoría de las madres utilizaron dos métodos de depleción mamaria (manual y con succión apretada). El estudio identificó que el volumen de leche empobrecida fue menor de que lo esperado por el Ministerio de Salud. Destacamos la falta de demanda del banco de leche por agotamiento, problemas relacionados con la mama, como ejemplo del método utilizado para el agotamiento.
RESUMO
Objectives: The study was intended to verify the association between the gestational age of newborns classified as term and the success of breastfeeding in babies born by elective cesarean section. Also, to analyze how the variability of gestational age within the term influences breastfeeding. Materials and Methods: Retrospective study of a cohort, which included full-term newborns and their mothers, whose deliveries occurred by elective cesarean section. Among the inclusion criteria are delivery due to elective cesarean section and minimum gestational age of 37 weeks. The database consisted of medical birth information and interviews with mothers. Results: This study included 954 full-term newborns born by elective cesarean section. Exclusive breastfeeding at 3 months and being breastfed at 6 months showed a statistically significant association in the correlation with the variability of gestational age. There was a statistically significant association between exclusive breastfeeding at 3 months and breastfeeding at 6 months in the correlation between early term and full term. The trend test showed a significant progressive in the breastfeeding curve versus gestational age. Conclusion: Full-term newborns show better results of exclusive breastfeeding at 3 months and continued breastfeeding at 6 months, compared with those born at early term. Gestational age, even in term, has an influence on the success of breastfeeding in newborns undergoing elective cesarean delivery.

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.

BACKGROUND: The effects of antenatal corticosteroids (ANSs) on twins are not well established. OBJECTIVE: To determine the impact of ANS use according to the number of fetuses. METHODS: Retrospective cohort study of newborns between 23 and 33 weeks of gestational age, birth weight from 400 to 1499 g, without malformations, delivered at 20 public university hospitals from 2010 to 2014.Exposed group: Received ANS (any time, any dose) and no exposed group: no received ANS. Analysis of birth conditions and clinical outcomes. Association of variables, relative risks, and 95% confidence intervals estimated from the adjustment of log-binomial regression models. RESULTS: About 7165 premature infants were analyzed: 5167 singleton, 937 twins, and 104 triplets. Characteristics of gestations with one, two, or three fetuses not receiving ANS were similar. Reduced hemodynamic instability in single and twins gestations in the first 72 h were observed (Adj R2 Twins = 0.78; 95% CI = 0.69-0.86) (Adj R2 Singles = 0.79; 95% CI = 0.62-0.99). Reduced peri-intraventricular hemorrhage (Adj R2 Twins = 0.54; 95% CI = 0.36-0.78) (Adj R2 singles = 0.54; 95% CI = 0.36-0.78); and early sepsis reduction on single and triplex gestations (Adj R2 triplex = 0.51; 95% CI = 0.27-0.94) (Adj single R2 = 0.51; 95% CI = 0.27-0.94) were observed. CONCLUSIONS: This study demonstrates ANS produces an important protective factor for severe intraventricular hemorrhage and hemodynamic instability in single and multiple pregnancies. ANS had a protective effect on death and birth conditions improvement just in single gestations. Regarding respiratory aspects was not observed the protective effect in the single or multiple gestations.

Abstract Objective: To determine the prevalence of life support limitation (LSL) in patients who died after at least 24 h of a pediatric intensive care unit (PICU) stay, parent participation and to describe how this type of care is delivered. Methods: Retrospective cohort study in a tertiary PICU at a university hospital in Brazil. All patients aged 1 month to 18 years who died were eligible for inclusion. The exclusion criteria were those brain death and death within 24 h of admission. Results: 53 patients were included in the study. The prevalence of a LSL report was 45.3%. Out of 24 patients with a report of LSL on their medical records only 1 did not have a donot-resuscitate order. Half of the patients with a report of LSL had life support withdrawn. The length of their PICU stay, age, presence of parents at the time of death, and severity on admission, calculated by the Pediatric Index of Mortality 2, were higher in patients with a report of LSL. Compared with other historical cohorts, there was a clear increase in the prevalence of LSL and, most importantly, a change in how limitations are carried out, with a high prevalence of parental participation and an increase in withdrawal of life support. Conclusions: LSLs were associated with older and more severely ill patients, with a high prevalence of family participation in this process. The historical comparison showed an increase in LSL and in the withdrawal of life support.

OBJECTIVE: To evaluate the use of cerebrospinal fluid (CSF) ferritin levels in the diagnosis of purulent meningitis (PM). METHOD: We studied 81 children between 28 days and 12 years of age who presented with clinical suspicion of meningitis to the emergency department. CSF ferritin levels were measured and compared between diagnostic groups (PM, aseptic meningitis (AM) and no meningitis). RESULTS: The median age was 24 (IQR 8-69) months. There were 32 patients with AM (39%), 23 with PM (28%) and 26 with no meningitis (32%). Median CSF ferritin was 4.2 ng/mL (IQR 3.0-6.5), 52.9 ng/mL (IQR 30.7-103 ng/mL) and 2.4 ng/mL (IQR 2-4), respectively. CSF ferritin was higher in children with PM compared with AM (p<0.001) or no meningitis (p<0.001). There was no difference between AM and no meningitis. CONCLUSION: CSF ferritin may be a useful biomarker to discriminate PM in children with clinical symptoms of this disease.

BACKGROUND: Retinochoroiditis is the most frequent manifestation of congenital toxoplasmosis. We aimed to describe the ocular outcome and factors that may influence the visual prognosis of these patients. METHODS: Cohort of patients with confirmed congenital toxoplasmosis seen between 1996 and 2017 in Porto Alegre, southern Brazil. RESULTS: Seventy-seven patients were included, of which 65 (85.5%) were identified by routine screening. Median age at the end of the follow-up was 10 years (minimum 2, maximum 25). Retinochoroiditis was present in 55 patients (71.4%). New retinochoroidal lesions developed after the first year of life in 77.8% of the patients who began treatment after the fourth month of life, compared with 35.2% among those treated before 4 months of life (relative risk = 0.45, 95% confidence intervals: 0.27-0.75, P = 0.02) and 33.3% among those treated before 2 months of life (relative risk = 0.42, 95% confidence intervals: 0.25-0.72, P = 0.01). There was a peak incidence of new retinochoroidal lesions between 4 and 5 years and another peak between 9 and 14 years, the latter only among girls. Thirty-four patients with retinochoroiditis were followed up for 10 years or more, and the school performance was appropriate in 28 (82.4%). CONCLUSIONS: The high incidence of new retinochoroidal lesions during the follow-up period indicates the importance of long-term follow-up of patients with congenital toxoplasmosis. Initiating treatment within the first 4 months of life, especially within the first 2 months, was a protective factor against the later development of retinochoroiditis. Despite the usual favorable prognosis, the high morbidity of congenital toxoplasmosis in Brazil was confirmed.

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.
