RESUMO

OBJECTIVE: To evaluate associations between change in weight z score after neonatal intensive care unit (NICU) discharge and neurodevelopmental outcomes and obesity at 12-48 months of age among individuals born very preterm. STUDY DESIGN: This secondary analysis used data from infants born very preterm participating in the Environmental influences on Child Health Outcomes cohort (n = 1400). Growth during infancy was calculated as change in weight z score between NICU discharge and follow-up at a mean of 27 months of age. Very low weight gain was defined as a change in weight z score <-1.67; very high weight gain was a change in weight z score >1.67. Neurodevelopmental outcomes included the Bayley Scales of Infant and Toddler Development, Child Behavior Checklist 1.5-5 years, and Modified Checklist for Autism in Toddlers. Multivariable linear regression was used to estimate associations between increase in weight z score and neurodevelopmental outcomes. RESULTS: Very low weight gain between NICU discharge and follow-up (experienced by 6.4% of participants) was associated with lower scores on cognitive (adjusted mean difference: -4.26; 95% CI: -8.55, -0.04) and language (adjusted mean difference: -4.80; 95% CI: -9.70, -0.11) assessments. Very high weight gain (experienced by 13.6% of participants) was associated with an increased obesity risk (adjusted relative risk: 6.20; 95% CI: 3.99, 9.66) but not with neurodevelopmental outcomes. CONCLUSIONS: Very high weight gain in the first 12-48 months after NICU discharge was associated with a higher risk of obesity at follow-up; very low weight gain was associated with lower scores on cognitive and language assessments.

RESUMO

To compare different criteria for the diagnosis of periodontitis and to evaluate the association of this condition with prematurity, this case-control study was conducted on 283 mothers of infants, divided into two groups based on gestational age (cases: <37 weeks, controls: ≥37 weeks), with 71 cases and 212 controls. The periodontal evaluation included probing depth (PD), clinical attachment level (CAL), plaque index, and bleeding on probing (BOP). Participants were classified regarding periodontitis per 14 criteria based on different periodontal parameters. The criterion selected as the gold standard was the presence of at least four teeth with one or more sites with a PD ≥ 4 mm, CAL ≥ 3 mm, and BOP at the same site. The prevalence of periodontal disease ranged from 8.1% to 55.1%. Moreover, compared to the gold standard, the sensitivities of the other criteria were 100%, while specificity ranged from 50.4% to 96.4%. Periodontitis, defined by six of the selected criteria, was associated with prematurity after multivariate adjustment, with OR ranging from 1.85 to 2.69 and 95% CI from 1.01 to 5.56; one of them was the gold standard mentioned above. Measurements using the clinical parameters of PD, CAL, and bleeding at the same site (criteria 5, 6, 7, 8), CPI (criterion 10), and at least four teeth with a PD ≥ 4 mm and CAL ≥ 3 mm (criterion 11) to define periodontitis showed a statistically significant association (p < 0.05). Given this study's limitations, we can conclude that the diagnostic criteria for a periodontitis definition using a PD ≥ 4 mm and CAL ≥ 3 mm in two or more teeth, with BOP at the same site, seem stronger when detecting an association between periodontitis and prematurity.

RESUMO

BACKGROUND AND OBJECTIVES: Red blood cell transfusions are frequent in preterm neonates. The proportion of preterm neonates transfused in Brazil remains unknown. We systematically reviewed the literature to estimate the frequency of red blood cell transfusions in preterm neonates in Brazil. MATERIALS AND METHODS: The LILACS, EMBASE, Cochrane, SciELO, MEDLINE (PubMed), Web of Science, Scopus, BDTD and 27 national university institutional databases were searched for studies that analysed red blood cell transfusion in preterm neonates in Brazil without period restriction. The Preferred Reporting Items in Systematic Reviews and Meta-Analyses guidelines were followed, and the GRADE methodology was applied. A random-effects model along with the restricted maximum likelihood method was used, and the Freeman-Tukey transformed proportion was used to estimate effect size. RESULTS: Nine studies, representing 6548 preterm neonates, were included in the qualitative and quantitative analyses. The mean gestational age ranged from 26.0 to 31.6 weeks. Most of the studies were from the Southeast region. The pooled estimated frequency of red blood cell transfusions was 58.0% (95% confidence interval = 52.0%-64.0%, p < 0.001) with low certainty. There was statistically significant heterogeneity among studies (I2 = 92.5%, p < 0.001). CONCLUSION: In this current meta-analysis of the evidence available, which included moderate and extremely preterm neonates, the observed frequency of red blood cell transfusions in preterm neonates in Brazil was 58.0% and this estimate can help health programming. Some Brazilian regions were not included in this study, and further research is needed to provide a more representative overview of Brazil.

RESUMO

ABSTRACT Objective: To assess early-onset sepsis as a risk factor of peri-intraventricular hemorrhage in premature infants born at less than or equal to 34 weeks' gestation and admitted to a neonatal intensive care unit (NICU). Methods: This retrospective cohort study included premature patients born at less than or equal to 34 weeks' gestation who were admitted to the NICU of a tertiary hospital in southern Brazil, and born from January 2017 to July 2021. Data were collected from patients' medical records. Early-onset sepsis was measured according to the presence or absence of diagnosis within the first 72 hours of life, whereas the outcome, peri-intraventricular hemorrhage, was described as the presence or absence of hemorrhage, regardless of its grade. Results: Hazard ratios were calculated using Cox regression models. A total of 487 patients were included in the study, of which 169 (34.7%) had some degree of peri-intraventricular hemorrhage. Early-onset sepsis was present in 41.6% of the cases of peri-intraventricular hemorrhage, which revealed a significant association between these variables, with increased risk of the outcome in the presence of sepsis. In the final multivariate model, the hazard ratio for early-onset sepsis was 1.52 (95% confidence interval 1.01-2.27). Conclusion: Early-onset sepsis and the use of surfactants showed to increase the occurrence of the outcome in premature children born at less than or equal to 34 weeks' gestation. Meanwhile, factors such as antenatal corticosteroids and gestational age closer to 34 weeks' gestations were found to reduce the risk of peri-intraventricular hemorrhage.

RESUMO Objetivo: O objetivo do presente trabalho foi avaliar a sepse precoce como fator de risco para hemorragia peri-intraventricular (HPIV) em prematuros com 34 semanas ou menos, admitidos em Unidade de Terapia Intensiva (UTI) Neonatal. Métodos: Este estudo de coorte retrospectivo incluiu pacientes prematuros com 34 semanas ou menos, que receberam alta da UTI Neonatal de hospital terciário, no sul do Brasil, nascidos no período de janeiro de 2017 a julho de 2021. Os dados foram coletados por meio dos prontuários desses pacientes. A sepse precoce foi mensurada conforme a presença ou a ausência do diagnóstico nas primeiras 72 horas de vida. Já o desfecho, hemorragia peri-intraventricular, foi descrito conforme a presença ou ausência da hemorragia, independentemente do grau. Resultados: Hazard ratios (HR) foram calculados por meio de modelos de regressão de Cox. Foram incluídos no estudo 487 pacientes. Destes, 169 (34,7%) apresentaram algum grau de hemorragia peri-intraventricular. A sepse precoce esteve presente em 41,6% dos casos de hemorragia peri-intraventricular e apresentou associação significativa, elevando o risco do desfecho quando presente. No modelo multivariável final, o HR para a sepse precoce foi de 1,52 (intervalo de confiança de 95% — IC95% 1,01-2,27). Conclusão: Sepse precoce e uso de surfactante demonstraram aumentar a ocorrência do desfecho em crianças prematuras até 34 semanas, enquanto fatores como corticoide antenatal e idades gestacionais mais próximas a 34 semanas mostraram reduzir o risco de ocorrência hemorragia peri-intraventricular.

Conclusion Most studies found no significant relationship between prematurity and difficulties in the progression of food consistencies during the introduction of complementary feeding; only three studies demonstrated such a relationship.

RESUMO

ABSTRACT Objective: To perform a cross-cultural adaptation and assess the content validity of the Neonatal Medical Index (NMI) for the Brazilian context. Methods: The cross-cultural adaptation was completed in six steps, including translation, synthesis of translations, back translation, submission to an expert committee, testing of the prefinal version, and appraisal by the original author. The expert committee assessed the equivalence between versions based on the percentage of agreement, and content validity was evaluated using the content validity index (CVI) for each item of the scale (I-CVI) and for the overall scale (S-CVI) in terms of representativeness and clarity. Participants of the prefinal version also evaluated the CVI for clarity. Results: After two evaluation rounds of the expert committee it was attained 98% agreement, attesting to the equivalence between the instrument versions, maximum values for representativeness I-CVI and S-CVI/Ave (1.00), and high values for clarity I-CVI (all items ≥0.97) and S-CVI/Ave (0.98). The expert committee members defined that the Brazilian version of the instrument would be called Índice Clínico Neonatal (NMI-Br). The NMI-Br reached high values of CVI for clarity (all I-CVI ≥0.86 and S-CVI/Ave=0.99) among the participants of the prefinal version. Conclusions: The NMI-Br is the Brazilian version of the NMI, obtained in a rigorous cross-cultural validation process, counting with adequate values of content validity.

Os participantes da versão pré-final também avaliaram o IVC quanto à clareza. Resultados: Após duas rodadas de avaliação do comitê de especialistas obteve-se 98% de concordância, atestando a equivalência entre as versões do instrumento, valores máximos para representatividade I-IVC e S-IVC/Ave (1,00) e altos valores para clareza I-IVC (todos os itens ≥0,97) e S-IVC/Ave (0,98). Os membros do comitê de especialistas definiram que a versão brasileira do instrumento se chamaria Índice Clínico Neonatal (NMI-Br). O NMI-Br alcançou altos valores de IVC para clareza (todos I-IVC ≥0,86 e S-IVC/Ave=0,99) entre os participantes da versão pré-final. Conclusões: O NMI-Br é a versão brasileira do NMI, obtido em rigoroso processo de validação transcultural, contando com valores adequados de validade de conteúdo.

RESUMO

Introducción: El parto prematuro y el bajo peso al nacer constituyen un problema de salud a escala mundial, ya que representan un predictor importante del desarrollo y crecimiento posnatal, así como un indicador de morbilidad y mortalidad infantil. Objetivo: Caracterizar a madres con recién nacidos prematuros y de bajo peso según variables clínicas y epidemiológicas. Métodos: Se realizó un estudio descriptivo, de corte transversal, desde enero hasta diciembre de 2022, de 35 madres con recién nacidos prematuros y de bajo peso, pertenecientes al Policlínico Docente Área Este de la ciudad de Camagüey. Entre las variables analizadas figuraron: edad, estado nutricional, clasificación del riesgo, control prenatal, riesgo reproductivo preconcepcional, consulta multidisciplinaria, enfermedades propias del embarazo, estado al nacer, deficiencias detectadas y causas. Resultados: En la serie predominaron el grupo etario de 35 y más años (25,7 %), la obesidad (37,1 %), las madres con elevados riesgos (45,7 %), quienes recibieron entre 8-14 controles prenatales, y malos antecedentes obstétricos (31,4 %). Por otra parte, 22,9 % de las madres tuvieron hijos con bajo peso y 31,4 %, prematuros; en tanto, hubo dificultades en el seguimiento por ausencias (57,1 %). Conclusiones: Las madres presentaron características clínicas y epidemiológicas desfavorables, tales como la edad de 35 y más años, la obesidad, el alto riesgo, los malos antecedentes obstétricos y la infección vaginal como enfermedad propia del embarazo, que influyeron en que los neonatos fueran prematuros o de bajo peso, o ambos.

Introduction: Preterm birth and low birth weight constitute a health problem worldwide, since they represent an important predictor of development and postnatal growth, as well as an indicator of newborn morbidity and mortality. Objective: To characterize mothers with preterm and low weight infants according to clinical and epidemiological variables. Methods: A descriptive, cross-sectional study was carried out from January to December, 2022, of 35 mothers with preterm and low weight infants, belonging to the East Area Teaching Polyclinic in Camagüey city. Age, nutritional state, risk classification, prenatal control, preconcepcional reproductive risk, multidisciplinary visits, diseases characteristic of pregnancy, birth state, detected deficiencies and causes were among the analyzed variables. Results: In the series there was prevalence of the 35 and over age group (25.7%), obesity (37.1%), high risk mothers (45.7%) who received among 8-14 prenatal controls, and bad obstetric history (31.4%). On the other hand, 22.9% of the mothers had low weight children and 31.4% preterm children; as long as there were difficulties in follow up due to absences (57.1%). Conclusions: The mothers presented unfavorable clinical and epidemiological characteristics, such as the 35 and over years, obesity, high risk, bad obstetric history and vaginal infection as a disease characteristic of pregnancy, which influenced the infants to be preterm or low weight, or both.

As populações mais vulneráveis a essa enfermidade são recém-nascidos de baixo peso,expostos ao ambiente de terapia intensiva neonatal. Objetivos: Identificar o perfil de recém-nascidos e os fatores maternos e neonatais associados à ocorrência de óbitos por enterocolite necrosante, em maternidade de referência do Ceará-Brasil. Metodologia: Trata-se de coorte retrospectiva, estudo que objetiva a descrição da incidência de determinado evento ao longo do tempo, além do estabelecimento de relações causais entre os fatores associados ao acontecimento. Incluíram-serecém-nascidos que tiveram óbitos por enterocolite necrosante entre 2019 e 2021, comficha de investigação de óbitos neonatais preenchida corretamente, não sendo excluído nenhum recém-nascido, totalizando amostra de 29 óbitos.Resultados: Identificou-se que o perfil dos recém-nascidos foi,em maioria, deprematuros e com baixo peso e fatores de risco para outras doenças associadas,como a sepse, o que acarretourealização de procedimentos invasivos e internação em ambiente de terapia intensiva neonatal.Conclusões: A prematuridade e o baixo peso ao nascer foram as variáveis relevantes no estudo e podem estar associadas à piora das condições clínicas do recém-nascido e ao desenvolvimento de enterocolite necrosante (AU).

Introduction: Necrotizing Enterocolitis is a disease that can affect the gastrointestinal tract of newborns, whose clinical manifestations can be characterized by bilious vomiting, blood in stool, abdominal distension, in addition to changes in hemodynamic parameters and thermal instability. The populations most vulnerable to this disease are low birth weight newborns exposed to the neonatal intensive care environment. Objectives: This study aimed to identify the profile of newborns and maternal and neonatal factors associated with the occurrence of deaths from necrotizing enterocolitis in a reference maternity hospital in Ceará, Brazil. Methodology: This is a retrospective cohort study seeking to describe the incidence ofa particular event over time, as well as establish causal relationships between the factors associated with the event. The study population comprised newborns who died from necrotizing enterocolitis between 2019 and 2021, who had neonatal death investigation forms filled out correctly, with no newborns being excluded, totaling a sample of 29 deaths. Results: It was identified that the profile of newborns was mostly premature, of low birth weight and with risk factors for other associated diseases such as sepsis, leading to invasive procedures and hospitalization in a neonatal intensive care environment. Conclusions: Prematurity and low birth weight were relevant variables in the study and may be associated with worsening of the newborn's clinical conditionsand development of necrotizing enterocolitis (AU).

RESUMO

High-risk newborns are exposed to neonatal conditions such as prematurity, very low birth weight, and congenital malformations that can affect development and behavior. Coronavirus disease 2019 (COVID-19) restraint and control measures have been identified as important stressor events and cumulative risk factors for behavioral changes in these children. This study examined social isolation-related factors that contribute to internalizing and externalizing behavior problems in children already at risk for neurodevelopmental disorders. This cross-sectional, multicenter study included 113 children (18 months to 9 years) who were followed in reference services for neonatal follow-up in tertiary units of the public health system in the city of Rio de Janeiro, Brazil. Behavior was assessed using the child behavior checklist, and a structured questionnaire was used to assess sociodemographic aspects. In the bivariate analysis, prematurity was associated with externalizing problems and change in eating habits with internalizing problems. The logistic model indicated that both parents having completed high school and both sharing care of the child were protective factors for behavioral problems; however, reports of sleep problems and living with another child were risk factors. In conclusion, the study identified internalizing and externalizing behavior problems related to prematurity and aspects of family structure and routine in children at risk. The findings confirm the importance of family functioning for child health and family-centered interventions.

RESUMO

OBJECTIVES: To evaluate the prevalence and perinatal repercussions of preeclampsia (PE) after the implementation of a prophylaxis protocol with aspirin in singleton pregnancy at Maternity School of Federal University of Rio de Janeiro, Rio de Janeiro, Brazil (2015-2106). METHODOLOGY: PE prevalence according to gestational age (GA) and the prevalence ratio (PR) between PE and prematurity, small for gestational age (SGA), and fetal death were calculated in patients assisted during 2015 and 2016. RESULTS: PE occurred in 373(10.75%) of 3468 investigated cases, where PE < 37 weeks was of 2.79% and PE greater than 37 weeks was of 7.95%. A total of 413 (11.9%) prematurity cases, 320 SGA (9.22%), and 50 fetal deaths (1.44%) occurred. In the PE group, 97 premature newborns (PR 0.90) and 51 SGA (PR 1.16) were born, and two fetal deaths occurred (PR 7.46). Concerning PE < 37 weeks, 27 SGA cases (PR 1.42) and two fetal deaths (PR 2.62) were observed. Regarding PE greater than 37 weeks, 24 SGA (PR 1.09) were born, and no fetal deaths were observed. Our findings were compared to previously published results. CONCLUSIONS: PE was significantly associated with SGA newborns, especially premature PE. Prescribing aspirin for PE prophylaxis based only on clinical risk factors in a real-life scenario does not appear to be effective but resulted in a PE screening and prophylaxis protocol review and update at ME/UFRJ.

RESUMO

OBJECTIVES: Determine the frequency of dermatological diagnoses in preterm newborns up to 28 days of life and associated perinatal factors. METHOD: a cross-sectional analytical study with a convenience sample and prospective data collection, was conducted between November 2017 and August 2019. Overall, 341 preterm newborns who had been admitted to a University hospital - including those admitted to the Neonatal Intensive Care Unit - were evaluated. RESULTS: 61 (17.9%) had less than 32 weeks gestational age (GA), with a mean GA and birth weight of 33.9 ± 2.8 weeks and 2107.8 ± 679.8g (465 to 4230g), respectively. The median age at the time of evaluation was 2.9 days (4 h to 27 days). The frequency of dermatological diagnoses was 100% and 98.5% of the sample had two or more, with an average of 4.67+1.53 dermatoses for each newborn. The 10 most frequent diagnoses were lanugo (85.9%), salmon patch (72.4%), sebaceous hyperplasia (68.6%), physiological desquamation (54.8%), dermal melanocytosis (38.7%), Epstein pearls (37.2%), milia (32.2%), traumatic skin lesions (24%), toxic erythema (16.7%), and contact dermatitis (5%). Those with GA< 28 weeks showed more traumatic injuries and abrasions, whereas those with ≥ 28 weeks had physiological changes more frequently, and those with GA between 34-366/7 weeks, had transient changes. CONCLUSION: Dermatological diagnoses were frequent in our sample and those with higher GA showed a higher frequency of physiological (lanugo and salmon patch) and transient changes (toxic erythema and miliaria). Traumatic lesions and contact dermatitis were among the 10 most frequent injuries, reinforcing the need to effectively implement neonatal skin care protocols, especially in preterm.

RESUMO

OBJECTIVES: To examine whether presenting a 30% or a 60% chance of survival in different survival information formats would influence hypothetical periviable birth treatment choice and whether treatment choice would be associated with participants' recall or their intuitive beliefs about the chances of survival. STUDY DESIGN: An internet sample of women (n = 1052) were randomized to view a vignette with either a 30% or 60% chance of survival with intensive care during the periviable period. Participants were randomized to survival information presented as text-only, in a static pictograph, or in an iterative pictograph. Participants chose intensive care or palliative care and reported their recall of the chance of survival and their intuitive beliefs about their infant's chance of survival. RESULTS: There was no difference in treatment choice by presentation with a 30% vs 60% chance of survival (P = .48), by survival information format (P = .80), or their interaction (P = .18). However, participants' intuitive beliefs about chance of survival significantly predicted treatment choice (P < .001) and had the most explanatory power of any participant characteristic. Intuitive beliefs were optimistic and did not differ by presentation of a 30% or 60% chance of survival (P = .65), even among those with accurate recall of the chance of survival (P = .09). CONCLUSIONS: Physicians should recognize that parents may use more than outcome data to make treatment choices and in forming their own, often-optimistic, intuitive beliefs about their infant's chance of survival.

RESUMO

INTRODUCTION: The effect of gestational age and fetal growth on the oxidant/antioxidant status of breast milk is poorly understood. OBJECTIVE: To evaluate the oxidative stress biomarkers in colostrum and mature milk according to gestational age and fetal growth. METHOD: A longitudinal study with mothers of premature and term infants, born in a tertiary referral hospital between 2014-2018. Inclusion criteria: postpartum women with a singleton pregnancy, who intended to exclusively breastfeed. Exclusion criteria: maternal diabetes, use of medication, drug addiction, congenital infection or malformation, mastitis, and failure to collect colostrum. Four groups were formed according to gestational age and birth weight (appropriate and small): Preterm small (n = 37), Preterm appropriate (n = 99), Full-term small (n = 65), and Full-term appropriate (control, n = 69). The colostrum samples were collected between 24-72 h and the mature milk was sampled in the 4th week of lactation for malondialdehyde (biomarker for lipid peroxidation) and Glutathione peroxidase, Catalase, and Superoxide dismutase measurements. The data were compared among groups using the Chi-square test or Fisher's exact test, one-way analysis of variance followed by Wald's Distribution test and repeated measures analysis of variance. RESULTS: We found a lower malondialdehyde level in colostrum in preterm groups and term small for gestational age, and the antioxidant enzymes Superoxide dismutase and Catalase activities were higher for preterm compared to term groups. The malondialdehyde levels differed in mature milk samples (Full-term small > Full-term appropriate > Preterm small > Preterm appropriate). The malondialdehyde levels increased during lactation in all groups except Preterm appropriate, and the levels of Catalase decreased in preterm groups. CONCLUSION: The oxidative status in breast milk is influenced by gestational age and fetal growth, which increased antioxidant defense for preterm infants and decreased oxidative stimuli for small for gestational age infants. These findings contribute to encouraging breastfeeding for newborns.

RESUMO

BACKGROUND: Multisensory interventions, such as auditory-tactile-visual-vestibular intervention (ATVV), tactile-kinesthesic stimulation (TKS), and the kangaroo mother care (KMC), have been commonly applied in hospitalized preterm infants. OBJECTIVE: To investigate the effectiveness of the ATVV, the TKS, and the KMC combined to standard care compared to standard care in the length of hospital stay and weight gain of hospitalized preterm infants. METHODS: PubMed, Scopus, Web of Science, Embase, SciELO Citation Index, CINAHL, Cochrane, and LILACS databases were searched from the inception to May 06, 2022 without language restrictions. We included randomized controlled trials. Two independent reviewers selected studies and extracted information about participants, interventions, outcomes, and the risk of bias. The body of evidence was synthesized through GRADE. Data were pooled using a random-effects model. RESULTS: Sixty-three randomized clinical trials included a range of 20-488 preterm infants (gestational age=25 to <37 weeks). Evidence was low to very low due to risk of bias, inconsistency, and imprecision. Most studies presented some concerns about methodological quality. The ATVV and the KMC increased weight gain. The TKS reduced the number of days at the hospital and increased the daily weight gain and the total weight gain. CONCLUSIONS: Adding ATVV, TKS, or KMC to standard care was more effective than standard care alone to improve weight gain. Only the TKS combined with standard care was more effective than standard care alone to reduce the length of hospital stay.

RESUMO

OBJECTIVE: To evaluate the impact of a parenteral lipid emulsion containing fish oil compared with a soybean oil based-lipid emulsion on the cognitive outcome and behavior of preschool children with extremely low birth weight. STUDY DESIGN: This was a retrospective secondary outcome analysis of a randomized controlled trial performed between June 2012 and June 2015. Infants with extremely low birth weight received either a mixed (soybean oil, medium chain triglycerides, olive oil, fish oil) or a soybean oil-based lipid emulsion for parenteral nutrition. Data from the Kaufman Assessment Battery for Children II, the Child Behavior Checklist 1.5-5, and anthropometry were collected from medical charts at 5.6 years of age. RESULTS: At discharge, 206 of the 230 study participants were eligible. At 5 years 6 months of age, data of 153 of 206 infants (74%) were available for analysis. There were no significant differences in Kaufman Assessment Battery for Children II scores for Sequential/Gsm, Simultaneous/Gv, Learning/Glr, and Mental Processing Index (mixed lipid: median, 97.5 [IQR, 23.5]; soybean oil: median, 96 [IQR, 19.5]; P = .43) or Child Behavior Checklist 1.5-5 scores for internalizing problems, externalizing problems, or total problems (mixed lipid: median, 37 [IQR, 12.3]; soybean oil: median, 37 [IQR, 13.5]; P = .54). CONCLUSIONS: A RandomForest machine learning regression analysis did not show an effect of type of lipid emulsion on cognitive and behavioral outcome. Parenteral nutrition using a mixed lipid emulsion containing fish oil did not affect neurodevelopment and had no impact on child behavior of infants with extremely low birth weights at preschool age. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01585935.

RESUMO

PurposeThe emergence of multidrug-resistant (MDR) Gram-negative bacterial infections in the neonatal intensive care unit (NICU) is a major public health threat. Ceftazidime-avibactam (CAZ-AVI) provides a new option for treating infections caused by most beta-lactamase- and carbapenemase-producing Gram-negative bacteria in infants older than three months. However, treatment options are extremely limited, with no safety data available for preterm neonates. Here, we describe our experience regarding the safety and efficacy of off-label use of CAZ-AVI in a NICU in Brazil. Summary: We report a case of a premature infant (born at 29 weeks gestational age) treated with CAZ-AVI due to a bloodstream infection caused by MDR Klebsiella pneumoniae. Conclusion: Treatment with CAZ-AVI was safe and effective in our patient.

RESUMO

El conducto arterioso establece una conexión esencial entre la arteria aorta descendente proximal y la arteria pulmonar principal cerca del origen de la rama pulmonar izquierda, siendo vital durante la vida fetal y generalmente cerrándose poco después del nacimiento en la mayoría de los recién nacidos a término; no obstante, en recien nacidos pretermino, es común la persistencia del conducto arterioso debido a estímulos vasodilatadores que mantienen su permeabilidad y flujo sanguíneo constante, requiriendo enfoques de tratamiento que involucran la inhibición de la prostaglandina E2 y antiinflamatorios no esteroides, aunque la comparación de su eficacia con métodos conservadores sigue siendo poco clara, especialmente en recién nacidos prematuros extremos. La presente revisión tiene como objetivo proporcionar una comprensión de los mecanismos moleculares clave detrás de la fisiopatología del conducto arterioso persistente y su abordaje terapéutico.

The ductus arteriosus establishes an essential connection between the proximal descending aorta and the main pulmonary artery near the origin of he left pulmonary branch, being vital during fetal life and generally closing shortly after birth in most term newborns; However, in preterm infants, persistence of the ductus arteriosus is common due to vasodilator stimuli that maintain its patency and constant blood flow, requiring treatment approaches involving prostaglandin E2 inhibition and nonsteroidal anti-inflammatory drugs, although the comparison of their efficacy with conservative methods remains unclear, especially in extremely preterm infants. The present review aims to provide an understanding of the key molecular mechanisms behind the pathophysiology of patent ductus arteriosus and its therapeutic approach.

RESUMO

Introdução: A prematuridade é considerada a principal causa da mortalidade infantil a nível mundial. Por sua vez, o aleitamento materno aumenta a sobrevida do recém-nascido prematuro ao oferecer aporte nutricional adequado e fortalecer o sistema imunológico do bebê. Por conta das especificidades da prematuridade, as famílias podem enfrentar dificuldades em estabelecer e dar continuidade ao aleitamento materno. Nesse sentido, os aplicativos móveis são ferramentas tecnológicas que podem ser utilizados no processo de educação em saúde e promover hábitos de vida saudáveis, como a amamentação. Objetivos: Desenvolver e validar um aplicativo móvel sobre amamentação para a família do bebê pré-termo. Método: Trata-se de um estudo metodológico para construção de um aplicativo mobile, embasado na Problematização de Paulo Freire e no Design Instrucional Contextualizado, organizado em duas grandes etapas: desenvolvimento e validação do aplicativo. O conteúdo do aplicativo foi desenvolvido com base na literatura e na cartilha educativa "Cuidados com o bebê prematuro: orientações para a família". Um protótipo do aplicativo na versão pré-alfa, foi construído e enviado aos desenvolvedores e programadores com o conteúdo, incluindo a visão geral, público-alvo, expectativas do usuário, com indicação de multimeios como imagens, vídeos e animações, a serem criados. Com o aplicativo construído, experts na área da enfermagem validaram seu conteúdo e interface e especialistas da área de tecnologia da informação realizaram a validação de interface. A seleção desses avaliadores foi realizada por meio de critérios pré-estabelecidos, por conveniência, seguindo o método de bola de neve. Na análise dos dados, para as respostas dos avaliadores, foi calculado o Índice de Validação de Conteúdo, sendo considerado desejável, este igual ou superior a 0,70. Os dados obtidos foram tabulados no Microsoft Excel e analisados de forma descritiva por meio de frequência absoluta e relativa. Resultados: A partir da criação do conteúdo e dos multimeios, foi desenvolvido um protótipo na fase alfa e o design do aplicativo utilizando os softwares Adobe Photoshop®, Corel Draw®, Adobe Illustrator® e Adobe Animate®. O aplicativo foi desenvolvido para os sistemas operacionais Android e iOS com a linguagem de programação JavaScript® por meio do framework React Native® e a plataforma Expo, teve o conteúdo flexível e organizado em "Bebê prematuro", "Amamentação", "Banco de Leite", "Agenda do meu bebê", "Galeria do meu bebê" e "Diário", em consonância com o referencial teórico utilizado, para facilitar o encontro de temas de interesse e de necessidade no momento. O aplicativo construído recebeu o nome de "Breastfeeding Care - Cuidados na amamentação do bebê prematuro" e foi disponibilizado nas plataformas de teste das lojas da Apple® e Google®. A validação de conteúdo e de interface do aplicativo contou com 19 experts em enfermagem, sendo considerado validado, obtendo valores de IVC global de 0,97 e 0,96, respectivamente. Na etapa de validação de interface junto a dez experts em tecnologia, o aplicativo obteve um IVC global de 0,97. Todos os itens apresentaram IVC ≥ a 0,70, não sendo necessárias outras rodadas de validação e revisão. Conclusão: O aplicativo móvel foi desenvolvido e validado junto a experts em enfermagem e tecnologia da informação, sendo considerado uma tecnologia adequada a ser utilizada pelas famílias de bebês prematuros, capaz de auxiliar no processo de amamentação.

Introduction: Prematurity is considered the main cause of infant mortality worldwide. On the other hand, breastfeeding increases the survival of premature newborns by providing adequate nutritional support and strengthening the baby's immune system. Due to the specificities of prematurity, families may face difficulties in establishing and continuing breastfeeding. Thus, mobile applications are technological tools that can be used in health education process to promote healthy lifestyle habits, such as breastfeeding. Objectives: Develop and validate a mobile application on breastfeeding for the family of preterm infants. Method: This is a methodological study for the construction of a mobile application, based on Paulo Freire's Problematization and Contextualized Instructional Design, divided into two phases: application development and validation. The application content was based on literature the educational booklet "Care for the premature baby: guidelines for the family". A prototype of the application in alpha version was built and sent to developers and programmers with the content, including the overview, target audience, user expectations, recommendation of multimedia such as images, videos and animations to be created. With the application built, nursing experts validated its content and interface, and information technology experts performed interface validation. The selection of evaluators was based on pre-established criteria, by convenience, following the snowball method. For data analysis, to the evaluator's responses, the Content Validation Index (CVI) was calculated, with a CVI equal to or greater than 0.70 being considered desirable. The data obtained were tabulated in Microsoft Excel and analyzed descriptively using absolute and relative frequency. Results: From the creation of content and multimedia, it was developed a prototype in the alpha phase and the application design by using Adobe Photoshop®, Corel Draw®, Adobe Illustrator® and Adobe Animate® software. The application was developed for Android and iOS systems with the JavaScript® programming language through the React Native® framework and the Expo platform, the content was flexible and organized into "Premature baby", "Breastfeeding", "Milk bank", "My baby's schedule", "My baby's gallery" and "Diary", in line with the theoretical framework used, to facilitate the meeting of topics of interest and need at the moment. The application developed was called "Breastfeeding Care - Care in breastfeeding premature babies" and was made available on the test platforms of the Apple® and Google® stores. Application content and interface validation involved 19 nursing experts, being considered validated, obtaining global CVI values of 0.97 and 0.96, respectively. In the interface validation step with ten technology experts, the application obtained a global CVI of 0.97. All items had a CVI > 0.70, requiring no further rounds of validation or revision. Conclusion: The mobile application was developed and validated with experts in nursing and information technology, being considered a valid technology to be used by families of premature babies, capable of assisting in the breastfeeding process.
