RESUMO

Anemia is frequent in preterm infants. Red blood cell transfusion practices vary between different centers. The objective of this study was to review red blood cell transfusion practices in preterm infants between 2020 and 2021. This was a narrative review that included studies published on PubMed (Medline) and Web of Science between October 2020 and October 2021. Ten studies were included finally. Red blood cell transfusion frequency was variable. Some neonatal units did not report transfusion protocols. Most studies reported volumes of 10-15 ml/kg per transfusion. The implementation of an anemia care bundle and adoption of restrictive transfusion resulted in a reduction in the number of transfusions, the volume transfused, and a reduction in the rate of multiple transfusions. We suggest that neonatal units that care for preterm infants should have a transfusion protocol based on the best evidence available and this issue may improve.

A anemia é frequente nos bebês prematuros. As práticas de transfusão de glóbulos vermelhos variam entre os diferentes hospitais. O objetivo deste estudo foi revisar as práticas de transfusão de glóbulos vermelhos em bebês prematuros entre 2020 e 2021. Esta foi uma revisão narrativa que incluiu estudos publicados no PubMed (Medline) e Web of Science entre outubro de 2020 e outubro de 2021. Dez estudos foram definitivamente incluídos. A frequência de transfusão de glóbulos vermelhos foi variável. Algumas unidades neonatais não relataram protocolos de transfusão. A maioria dos estudos relatou volumes de 10-15 ml/kg por transfusão. A implantação de um conjunto de cuidados para anemia e a adoção de transfusão restritiva resultaram em uma redução do número de transfusões, do volume transfundido e uma redução na taxa de transfusões múltiplas. Sugerimos que as unidades neonatais que prestam cuidados a bebês prematuros devem ter um protocolo de transfusão baseado em evidências para que todo esse problema melhore.

RESUMO

INTRODUCTION: The low attendance of families in child developmental follow-up programs for at-risk preterm children is a challenge in Brazil. OBJECTIVE: This study evaluates the feasibility of implementing a developmental follow-up program for Brazilian preterm infants in a hybrid format. METHODS: This is an observational, prospective cohort study, involving preterm infants. Longitudinal developmental test results, the participation frequency in the program, and the number of referrals to early intervention programs were used to assess feasibility. The General Movements (GMs) assessment, Alberta Infant Motor Scale (AIMS) and, Survey of Wellbeing of Young Children (SWYC) Milestones were administered via telehealth. The Bayley-III was administered in-person. RESULTS: Thirty-four preterm infants attended the follow-up until 12 months of corrected age and 18 (52.9 %) concluded all follow-up assessments. Twenty-six (76.5 %) attended all assessments via telehealth, and 26 (76.5 %) attended the in-person assessment. Eighteen (52.9 %) infants showed at least one altered result in development tests. Infants exhibiting abnormal results in the GMs assessment, motor developmental delay according to the AIMS, or developmental delay based on Balley-III were promptly referred to early intervention services. CONCLUSION: This study demonstrated high participation rate and low dropout in a developmental follow-up program employing a hybrid format. The substantial number of identified infants with developmental delay emphasizes the importance of timely detection of motor delays to referral to early intervention services.

RESUMO

This study aims to analyze the main risk factors for acute kidney injury in the subgroup of very-low birth weight newborns, using the diagnosing criteria of the Kidney Disease Improving Global Outcomes (KDIGO) or the Acute Kidney Injury Network (AKIN). A systematic review of the literature was performed on the EMBASE® and PubMed® platforms. Studies that evaluated the risk factors for developing AKI in VLBW newborns were included. For the meta-analysis, we only included the risk factors that were associated with AKI in the univariate analysis of at least two studies. After an initial screening, abstract readings, and full-text readings, 10 articles were included in the systematic review and 9 in the meta-analysis. The incidence of AKI varied from 11.6 to 55.8%. All the studies have performed multivariate analysis, and the risk factors that appeared most were PDA and hemodynamic instability (use of inotropes or hypotension), sepsis, and invasive mechanical ventilation. After the meta-analysis, only cesarian delivery did not show an increased risk of AKI, all the other variables remained as important risk factors. Moreover, in our meta-analysis, we found a pooled increased risk of death in newborns with AKI almost 7 times.  Conclusion: AKI in VLBW has several risk factors and must be seen as a multifactorial disease. The most common risk factors were PDA, hemodynamic instability, sepsis, and invasive mechanical ventilation. What is known: • Acute kidney injury is associated with worst outcomes in all ages. It´s prevention can help diminish mortality. What is new: • A synthesis of the main risk factors associated with AKI in very low birth weight newborns.

RESUMO

PURPOSE: Predicting bronchopulmonary dysplasia (BPD) to assess the risk-benefit of therapy is necessary considering the side effects of medications. We developed and validated an instrument for predicting BPD and compared it with an instrument currently used for neonates born in a Brazilian hospital. METHODS: This was a retrospective cohort study of patients born between 2016 and 2020 with a gestational age (GA) between 23 and 30 weeks. Predictive equations were elaborated using methods of component variable selection collected on the 14th day of life; 70% of the sample was randomly selected for the construction of risk prediction equations and the remaining 30% for their validation, application, and comparison with the National Institute of Child Health and Human Development (NICHD) instrument. The sensitivity, specificity, and predictive values of the equations were calculated. RESULTS: The equation that used variables with p < 5% in Fisher's exact test presented the best results: specificity of 98% and positive predictive value of 93% and could be used for BPD prediction of all small-for-gestational-age (SGA) infants. The NICHD calculator applied to our population had a specificity of 93% and a positive predictive value of 75% and could not be applied to extremely SGA infants. CONCLUSION: Our tool can predict the risk of BPD on the 14th day of life, has higher specificity and positive predictive value to our population than the NICHD instrument, and can be suitable for SGA infants. The results must be confirmed by applying it to other populations to validate our tool.

RESUMO

Objective: To ascertain how screening for preterm birth is performed among obstetricians working in public and private practice in a middle-income country. Methods: Cross-sectional study of 265 obstetrician-gynecologists employed at public and private facilities. An online questionnaire was administered, with items designed to collect data on prematurity screening and prevention practices. Results: The mean age of respondents was 44.5 years; 78.5% were female, and 97.7% had completed a medical residency program. Universal screening (i.e., by ultrasound measurement of cervical length) was carried out by only 11.3% of respondents in public practice; 43% request transvaginal ultrasound if the manual exam is abnormal, and 74.6% request it in pregnant women with risk factors for preterm birth. Conversely, 60.7% of respondents in private practice performed universal screening. This difference in screening practices between public and private practice was highly significant (p < 0.001). Nearly all respondents (90.6%) reported prescribing vaginal progesterone for short cervix. Conclusion: In the setting of this study, universal ultrasound screening to prevent preterm birth was used by just over half of doctors in private practice. In public facilities, screening was even less common. Use of vaginal progesterone in cervical shortening was highly prevalent. There is an unmet need for formal protocols for screening and prevention of preterm birth in middle-income settings.

RESUMO

Background: According to the World Health Organization, tuberculosis (TB) ranks among the top 10 causes of death worldwide. The significance of TB during pregnancy lies in its symptoms, which can be mistaken for physiological changes associated with pregnancy. This confusion can lead to maternal-perinatal complications. Objective: To evaluate the association between pulmonary TB in pregnancy and adverse neonatal outcomes in two Peruvian hospitals. Methods: This is a retrospective cohort study. The target population consisted of pregnant women with and without pulmonary TB whose deliveries were attended at two public hospitals, located in Lima, Peru. The adverse neonatal outcomes were prematurity, low birth weight (LBW), and being small for gestational age (SGA). Crude and adjusted relative risks (RRa) were calculated with their respective 95% confidence intervals (95%CI). Results: Information from 212 patients was analyzed; 48.1% had TB during pregnancy, and 23.1% had adverse neonatal outcomes (8%, 11.3%, and 12.3% for LBW, prematurity, and SGA, respectively). In the adjusted model, pregnant women with pulmonary TB had a 3.52 times higher risk of having a newborn with at least one of the adverse outcomes than those who were not exposed (aRR, 3.52; 95%CI: 1.93-6.68). Conclusion: Pulmonary TB in pregnancy was jointly and independently associated with adverse neonatal outcomes, including LBW, prematurity, and being SGA.

RESUMO

RESUMEN La acondroplasia severa con retraso del desarrollo y acantosis nigricans (SADDAN) es una rara y letal displasia esquelética. Presentamos el primer caso detectado en Perú, en un infante de 13 meses con características fenotípicas de macrocefalia relativa, tórax estrecho, extremidades micromélicas y piel en acordeón; asimismo, un marcado retraso del desarrollo psicomotor en todos los hitos (prueba peruana) y acantosis nigricans. El paciente tuvo mala evolución clínica caracterizada por crisis convulsivas recurrentes, dificultad respiratoria progresiva, y falleció por insuficiencia respiratoria concomitante a neumonía. Esta entidad requiere del acceso a exámenes específicos como el panel de displasias esqueléticas, la cual no es parte de la oferta en la mayoría de los hospitales del Perú. Se requiere una mayor atención las enfermedades raras, a fin de proveer diagnósticos e información oportuna a los involucrados.

ABSTRACT Severe achondroplasia with developmental delay and acanthosis nigricans (SADDAN) is a rare and lethal skeletal dysplasia. We present the first case detected in Peru, in a 13-month-old infant with phenotypic characteristics of relative macrocephaly, narrow thorax, micromelic extremities and accordion skin; likewise, a marked delay in psychomotor development in all milestones (Peruvian test), and acanthosis nigricans. The patient had a poor clinical evolution characterized by recurrent seizures, progressive respiratory difficulty, dying from respiratory failure concomitant to pneumonia. This entity requires access to specific exams such as the skeletal dysplasia panel, which is not part of the offering in most hospitals in Peru. Greater attention is required for rare diseases, to provide timely diagnoses and information to those involved.

RESUMO

OBJECTIVE: To evaluate the effect of oropharyngeal colostrum immunotherapy (OCI) on the mortality of preterm newborns (PTNB) with very low birth weight (VLBW). METHOD: Non-randomized clinical trial, carried out with 138 mother-child pairs attended at a public maternity hospital. The treatment group used raw colostrum, dripping 4 drops (0.2 ml) into the oropharyngeal mucosa, totaling 8 administrations in 24 h, up to the 7th complete day of life (OCI). The control group was composed of newborns admitted to the same maternity hospital before the implementation of the OCI. Analyzes were performed: descriptive, bivariate, multiple logistic regression, and survival analysis, with a significance level of 5% and 95% CI. RESULTS: The treatment group had an RR of death of 0.26 (95% CI = 0.07-0.67; p = 0.00), adjusted for maternal age, marital status, gestational hypertension, type of delivery, number of prenatal visits, and birth weight. Number Needed to Treat (NNT) demonstrated that for every 5 individuals treated with OCI, one death was prevented NNT = 4.9 (95% CI = 1.84-5.20); however, for PTNB with VLBW who remained hospitalized for 50, 100 and 150 days, the NNT reduces to 4, 4 and 3, respectively. CONCLUSION: The OCI proved to be a beneficial intervention, since it reduced the risk of mortality in PTNB with VLBW when compared to the control group.

RESUMO

ABSTRACT Objective: To identify the type of feeding and analyze the sociodemographic and clinical factors associated with exclusive breastfeeding at hospital discharge, in the first and in the last follow-up visit of the third stage of the Kangaroo Mother Care among infants admitted to the kangaroo unit. Method: Longitudinal and retrospective study. A total of 186 infants of gestational age <37 weeks admitted to the kangaroo unit in 2018 and 2019 was included. Data collected from medical records and subjected to inferential analysis and the Poisson regression model (P < 0.05). Results: Exclusive breastfeeding rate was 73.1% at discharge, with a drop at the last follow-up visit (68.1%). At discharge, there was a greater probability of exclusive breastfeeding in younger mothers, with higher education, infants born with higher birth weight and who received exclusive human milk during hospitalization; in the first follow-up visit, in a younger mother and infant who received only human milk during hospitalization; and in the last follow-up visit, a young mother, infant who received only human milk and suckled at the breast for the first time in the kangaroo unit. Conclusion: Most infants hospitalized in the second stage of the Kangaroo Mother Care were exclusively breastfed and presented maternal and clinical factors related to breastfeeding. This fact can help manage the challenges of the method and promote breastfeeding.

RESUMEN Objetivo: Identificar el tipo de alimentación y analizar los factores sociodemográficos y clínicos asociados a la lactancia materna exclusiva al alta hospitalaria, en el primero y en la última visita de seguimiento de la tercera etapa del Método Madre Canguro entre los recién nacidos ingresados en la unidad canguro. Método: Estudio longitudinal y retrospectivo. Se incluyeron 186 neonatos en edad gestacional <37 semanas ingresados en la unidad canguro en 2018 y 2019. Datos recopilados de historias clínicas sometidas a análisis inferencial y modelo de regresión de Poisson (p < 0,05). Resultados: La tasa de lactancia materna exclusiva fue del 73,1% al alta, con descenso en la última visita de seguimiento (68,1%). Al alta hubo mayor probabilidad de lactancia materna exclusiva en madres más jóvenes, con mayor escolaridad, recién nacidos con mayor peso al nacer y que recibieron leche materna exclusiva durante la internación; en la primera visita de seguimiento, en una madre más joven y un recién nacido que recibió únicamente leche materna durante la hospitalización; y en la última visita de seguimiento, una madre joven, recién nacido que recibió sólo leche humana y con la primera succión del pecho en la unidad canguro. Conclusión: La mayoría de los recién nacidos hospitalizados en la segunda etapa del Método Madre Canguro fueron amamantados exclusivamente y presentaron factores maternos y médicos relacionados con la lactancia materna, que pueden ayudar a gestionar los desafíos del método y promover la lactancia materna.

RESUMO

ABSTRACT Objective: To evaluate the pattern of eye-gaze of preterm (PT), autism spectrum disorder (ASD) and neurotypical (Ty) children. Methods: A cross-sectional study with eight preterm (born with ≤2000 g weight), nine ASD and five Ty male children, between six and nine years old, was performed. The eye gaze was evaluated presenting a board with a couple in social interaction, and a video with four children playing with blocks, projected in a screen computer, successively, evaluating the time that the children looked at each stimulus. Results: Although all the groups focus on the central social figure with no significant differences, ASD presented significant differences in time fixation of the objects (p=0.021), while premature children fixated more time in the central social interaction than in the whole scene than typical children. Conclusions: Although this study found noteworthy differences in the eye-gaze patterns among the three groups, additional research with a more extensive participant pool is necessary to validate these preliminary results.

RESUMO Objetivo: Avaliar o padrão de fixação visual de crianças nascidas prematuras (PT), com transtorno do espectro do autismo (TEA/ASD) e neurotípicas (Ty). Métodos: Estudo transversal incluindo oito meninos prematuros (nascidos com peso ≤2000 g), nove TEA e cinco Ty, com idade entre 6 e 9 anos. A varredura visual foi avaliada apresentando-se imagem de casal em interação social e vídeo com crianças brincando. A figura e o vídeo foram projetados em tela de computador, sucessivamente, sendo avaliado o tempo de fixação para cada estímulo. Resultados: Apesar de os três grupos de crianças focarem o olhar na figura social central sem diferenças significativas, crianças com TEA apresentaram diferenças significativas no tempo de fixação em objetos (p=0,021), enquanto prematuros fixaram o olhar mais tempo na interação social central do que na cena como um todo. Conclusões: Embora tenham sido notadas algumas diferenças significativas nos padrões de olhar para os três grupos, é necessário realizar mais pesquisas com uma amostra maior para confirmar esses resultados iniciais.

RESUMO

Objective: To evaluate the rates of exclusive breastfeeding (EBF) and growth of preterm and/or low birth weight newborns during the third stage of the Kangaroo Method (TSKM), at discharge. Methods: Retrospective study in a reference public maternity hospital between Jan/2014 and Dec/2017, including the preterm (less than 37 weeks) and/or low birth weight (less than 2500 g) newborn infants. Information was collected from medical records. Statistics analysis was done in SPSS software. Results: 482 infants were included and followed up at the TSKM ambulatory. The average gestational age was 33 weeks (variation: 24-39 weeks) and birth weight, 1715g (variation: 455-2830 g). EBF occurred in 336 (70.1%) infants at hospital discharge, and in 291 (60.4%) at TSKM discharge. Each additional day of hospital stay increased the chance of infant formula (IF) use by 9.3% at hospital discharge and by 10.3% at TSKM discharge. Staying in the Kangaroo Neonatal Intermediate Care Unit (KNICU) favored EBF at hospital discharge and TSKM discharge (p<0.001). Not performing the kangaroo position increased the chance formula administration to the newborn infant at hospital discharge by 11%. Weight gain and head circumference growth were higher in infants using formula (p<0.001). Conclusions: The length of hospital stay and not performing the kangaroo position favored the use of infant formula at hospital and TSKM discharge. Staying in the KNICU favored exclusive breastfeeding at hospital and TSKM discharge. Weight gain and HC growth were higher in newborns receiving infant formula.

RESUMO Objetivo: Avaliar as taxas de aleitamento materno exclusivo e o crescimento dos recém-nascidos (RN) pré-termo e/ou de baixo peso ao nascer à alta da terceira etapa do Método Canguru (TEMC). Métodos: Estudo retrospectivo realizado em maternidade pública de referência entre janeiro/2014 e dezembro/2017, que incluiu os RN pré-termo (<37 semanas) e/ou de baixo peso (<2.500 g). As informações foram coletadas de prontuários médicos e analisadas pelo programa Statistical Package for the Social Sciences (SPSS). Resultados: Foram seguidos 482 RN, com mediana da idade gestacional de 33 semanas (variação: 24-39 sem) e peso ao nascer 1.715 g (variação: 455-2.830 g). O aleitamento materno exclusivo (AME) ocorreu em 336 (70,1%) RN à alta hospitalar e em 291 (60,4%) à alta da TEMC. Cada dia a mais de permanência hospitalar aumentou a chance do uso de fórmula infantil em 9,3% à alta hospitalar e em 10,3% à alta da TEMC. Permanecer na Unidade de Cuidados Intermediários Canguru (UCINCA) favoreceu o AME à alta hospitalar e da TEMC (p<0,001). Não realizar a Posição Canguru aumentou em 11% a chance de o RN utilizar fórmula infantil à alta hospitalar. O ganho de peso e crescimento do perímetro cefálico foram maiores nos RN em uso de fórmula infantil (p<0,001). Conclusões: O tempo de permanência hospitalar e a não realização da Posição Canguru favoreceram o uso de fórmula infantil à alta hospitalar e da TEMC. Permanecer na UCINCA favoreceu o AME à alta hospitalar e da TEMC. O ganho de peso e crescimento do PC foram maiores nos RN em uso de fórmula infantil.

RESUMO

ABSTRACT Objective: to construct and validate the content of a bundle for nutrition transition for premature newborns admitted to a Kangaroo Intermediate Care Unit based on Interactive Theory of Breastfeeding. Method: this is a multiple method research, carried out in five steps: systematic review; situational diagnosis; interview with Kangaroo Unit nurses; methodological step - (bundle construction with Interactive Theory of Breastfeeding application, pre-test); and content validity with expert judges and clinical nurses. The methodological step was carried out from January to July 2022 with Kangaroo Unit nurses of a public maternity hospital in Fortaleza-CE. Experts were invited by email using the snowball method. Validity occurred using a Content Validity Index >0.80. Results: the bundle was constructed using 13 items, distributed and organized into corrected age groups: corrected age of ≤32 weeks; from 32 to 34 weeks; and ≥ 34 weeks. In the validity step, the judges, three experts and seven clinical nurses, judged the bundle to be adequate, presenting a Content Validity Index of 1.0. Conclusion: given the lack of standardization for feeding transition in clinical practice, there is difficulty in recognizing the ideal moment to transition from orogastric tube feeding to mothers' breast. The food transition bundle, anchored by the Interactive Theory of Breastfeeding, allows nurses to assess the mother-child dyad, their particularities, time for both, maternal role, involving organizational systems to protect, promote and support breastfeeding.

Abstract Objective To analyze human milk sufficiency in Neonatal Intensive Care Units in the Metropolitan Region of São Paulo according to the number of premature babies, estimated demand for human milk and actual consumption. Methods This is a cross-sectional study, carried out at Human Milk Collection Stations and Human Milk Banks registered with the São Paulo Network of Human Milk Banks in 2017. Data from 2017 census vital statistics were used to identify premature baby distribution in Regional Health Care Networks. Results 100% of Human Milk Collection Stations and 84.6% of Human Milk Banks in São Paulo participated in the study. Pasteurized human milk distribution insufficiency was identified between estimated demand and actual consumption by premature babies. During the study period, only the Center and Southeast regions met 100% of human milk coverage, followed by the Greater ABC region, with 44.62%. Conclusion Most Human Milk Collection Stations and Human Milk Banks in the metropolitan region of São Paulo do not assist all premature children. The management of these units can contribute to encouraging donor recruitment and collected human milk optimization.

RESUMO

Abstract Objectives: to evaluate the effect of oropharyngeal colostrum immunotherapy on the length of hospital stay in preterm newborns with very low birth weight. Methods: interventional ambispective study, which consisted of eight daily administrations of 0.2 ml (four drops) of colostrum, totaling up to 56 syringes (for up to seven days). The control was historic. The main independent variable: length of hospital stay (days). Survival analysis was performed using the Kaplan-Meier Method and the survival effect was estimated - Log Rank Test (Mantel-Cox) and Breslow Test (Generalized Wilcoxon). A significance level of 5% was adopted. Results: of the 109 mother/child pairs, 56 were part of the treatment and 53 were part of the control group. There was no association between oropharyngeal colostrum immunotherapy and length of stay for preterm newborns with very low birth weight in the general sample. However, after stratification, a shorter hospital stay (42 versus 51 days, HR= 1.78, CI95%=1.02-3.09, p=0.04) was demonstrated among premature infants with ≥28 gestational weeks undergoing oropharyngeal colostrum immunotherapy. Conclusions: we found an association between oropharyngeal colostrum immunotherapy and shorter median length of hospital stay in the subgroup of premature infants ≥ 28 weeks of gestational age, but we did not find significant differences in those <28 weeks.

Resumo Objetivos: avaliar o efeito da imunoterapia orofaríngea de colostro no tempo de internamento hospitalar de recém-nascidos pré-termos de muito baixo peso. Métodos: estudo de intervenção, ambispectivo, que consistiu em oito administrações diárias de 0,2 ml (quatro gotas) de colostro, totalizando até 56 seringas (por até sete dias). O controle foi histórico. A variável independente principal: tempo de permanência hospitalar (dias). Realizada análise de sobrevivência pelo Método de Kaplan-Meier e estimado o efeito da sobrevida - Teste de Log Rank (Mantel-Cox) e Teste de Breslow (Wilcoxon Generalizado). Adotou-se o nível de significância de 5%. Resultados: das 109 duplas mães/filho, 56 fizeram parte da análise do grupo tratamento e 53 do controle. Não houve associação entre imunoterapia orofaríngea de colostro e tempo de internamento de recém-nascidos pré-termos de muito baixo peso na amostra geral. Após estratificação demonstrou-se menor tempo de permanência hospitalar (43 versus 51 dias, HR=1,78, IC95%= 1,02-3,09, p=0,04) entre os prematuros com ≥28 semanas gestacionais submetidos a imunoterapia orofaríngea de colostro. Conclusões: encontrou-se associação entre imunoterapia orofaríngea de colostro e menor mediana de tempo de internamento hospitalar no subgrupo de prematuros ≥ 28 semanas de idade gestacional, porém não foram encontradas diferenças significativas naqueles < 28 semanas.

RESUMO

Abstract Objectives: to evaluate the association between the time to initiate the first skin-to-skin contact (SSC) and the daily practice time with the rates of late-onset sepsis in newborns ≤1,800g. Methods: a multicentric cohort study was carried out at the neonatal units located in three Brazilian geographic regions. The SSC time was recorded in individual files by the hospital staff and the newborn's parents. Maternal and neonatal data were obtained from medical records and through questionnaires applied to the mothers. Data analysis was carried out using a tree algorithm classification, which divided the data set into mutually exclusive subsets that best described the variable response. Results: 405 newborns participated in the study, with an average of 31.3 ± 2.7 weeks and 1,412g (QR=1,164-1,605g) as a median birth weight. The first SSC was carried out within 137 hours of life (≤5.7 days) was associated with a lower rate of late sepsis (p=0.02) for newborns who underwent daily SSC of 112.5 to 174.7 min/day (1.9 to 2.9h/day), with a reduction in the sepsis rate from 39.3% to 27.5%. Furthermore, the duration of SSC >174.7min/day (>2.9h/day) was relevant (p<0.001) for newborns who weighed >1,344g, with a reduction in this rate from 24.1% to 6%. Conclusions: SSP has been proven to be significant in reducing late-onset sepsis rates in preterm newborns, especially when carried out in a timely manner (≤5.7 days) and prolonged (>2.9h/day).

Resumo Objetivos: avaliar a associação entre o tempo para iniciar o primeiro contato pele a pele (CPP) e o tempo diário praticado com a taxa de sepse tardia em recém-nascidos ≤1.800g. Métodos: coorte multicêntrica realizada em unidades neonatais de três regiões geográficas brasileiras. O CPP foi registrado em ficha individual pela equipe e pais do recém-nascido. Dados maternos e neonatais foram obtidos por questionários aplicados às mães e em prontuários médicos. A análise dos dados foi realizada por algoritmo da árvore de classificação, que dividiu o conjunto de dados em subconjuntos mutuamente exclusivos que melhor descreveram a variável resposta. Resultados: 405 recém-nascidos participaram do estudo, com média de 31,3±2,7 semanas de idade gestacional e mediana de peso ao nascer 1.412g (IQ=1.164-1.605g). Realizar o primeiro CPP com até 137h de vida (≤5,7 dias) foi associado a menor taxa de sepse tardia (p=0,02) para recém-nascidos que fizeram CPP diário de 112,5 a 174,7 min/dia (1,9 a 2,9h/dia), com redução na taxa de sepse (39,3% para 27,5%). Além disso, a duração do CPP>174,7min/dia (>2,9h/dia) foi relevante (p<0,001) para os recém-nascidos >1.344g, com redução nesse desfecho (21,1% para 6%). Conclusões: o CPP mostrou-se importante para redução das taxas de sepse tardia em recém-nascidos pré-termo, especialmente quando realizado de forma oportuna (≤5,7 dias) e prolongada (>2,9h/dia).

RESUMO

ABSTRACT Objective This study aimed to evaluate the prevalence of hypertensive disorders during pregnancy among Brazilian women with preterm births and to compare the epidemiological characteristics and perinatal outcomes among preterm births of women with and without hypertension. Methods This was a secondary cross-sectional analysis of the Brazilian Multicenter Study on Preterm Birth. During the study period, all women with preterm births were included and further split into two groups according to the occurrence of any hypertensive disorder during pregnancy. Prevalence ratios were calculated for each variable. Maternal characteristics, prenatal care, and gestational and perinatal outcomes were compared between the two groups using χ2 and t-tests. Results A total of 4,150 women with preterm births were included, and 1,169 (28.2%) were identified as having hypertensive disorders. Advanced maternal age (prevalence ratio (PR) 2.49) and obesity (PR= 2.64) were more common in the hypertensive group. The gestational outcomes were worse in women with hypertension. Early preterm births were also more frequent in women with hypertension. Conclusion Hypertensive disorders of pregnancy were frequent among women with preterm births, and provider-initiated preterm births were the leading causes of premature births in this group. The factors significantly associated with hypertensive disorders among women with preterm births were obesity, excessive weight gain, and higher maternal age.

RESUMO

ABSTRACT Objective: To analyze the cognitive development of preterm infants at six and 12 months of corrected age and the associations with perinatal and socioeconomic factors. Methods: Cognitive development of 40 infants (20 preterm and 20 full-term) at six and 12 months of age was evaluated using the Bayley-III scale. Correlations between cognitive outcome and associated factors were assessed using Spearman correlation. Stepwise multiple linear regression analysis with covariance was applied to identify changes on cognitive score between six and 12 months. Results: Bayley-III cognitive score in preterm group was significantly lower than in full-term group at both six and 12 months of age. Birth weight correlated with cognitive performance at six months and head circumference at birth at 12 months, in full-terms infants. The occurrence of necrotizing enterocolitis was inversely associated with cognitive score in preterms at 12 months. An increase in cognitive score was observed between six and 12 months in both groups, but the gain was more pronounced in preterms. Conclusions: These findings suggest some cognitive recovery capacity in the first year despite the restrictions imposed by premature birth and emphasize the importance of early interventions in this population.

RESUMO Objetivo: Avaliar o desenvolvimento cognitivo de crianças pré-termo aos seis e 12 meses de idade corrigida e as associações com fatores perinatais e socioeconômicos. Métodos: O desenvolvimento cognitivo de 40 crianças (20 pré-termo e 20 a termo) foi avaliado aos seis e 12 meses de idade, utilizando a escala Bayley-III. Correlações entre resultados cognitivos e fatores associados foram avaliadas pelo teste de correlação de Spearman. A análise de regressão linear múltipla stepwise com covariância foi aplicada para identificar mudanças na pontuação cognitiva entre seis e 12 meses. Resultados: O escore cognitivo no grupo pré-termo foi significativamente menor que no grupo a termo aos seis e 12 meses. O peso ao nascer foi diretamente associado com o desempenho cognitivo aos seis meses e perímetro cefálico ao nascimento aos 12 meses, nas crianças a termo. A ocorrência de enterocolite necrosante foi inversamente associada ao desempenho cognitivo em pré-termos, aos 12 meses. Verificou-se aumento na pontuação cognitiva entre seis e 12 meses nos dois grupos, porém mais pronunciado no pré-termo. Conclusões: O estudo sugere que crianças pré-termo apresentam alguma capacidade de recuperação cognitiva no primeiro ano, apesar das restrições impostas pelo nascimento prematuro, e enfatizam a importância de acompanhamento dessa população desde os primeiros meses de vida.

RESUMO

Resumo Objetivo Analisar as evidências disponíveis sobre a transição alimentar de sonda orogástrica para aleitamento materno diretamente na mama com prematuros internados em unidades hospitalares. Métodos Revisão sistemática da literatura com busca nas bases de dados PubMed/MEDLINE, Web of Science, EMBASE, Scopus, Cochrane CENTRAL, CINAHL, com os critérios de inclusão: estudos experimentais, sem restrição temporal e nos idiomas português, espanhol e inglês. A avaliação metodológica foi realizada por meio das ferramentas Grading of Recommendations Assessment, Development and Evaluation (GRADE) e Revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0) e consistiu em duas etapas: qualidade metodológica e o risco de viés dos estudos. Resultados Foram identificados 10 artigos, todos ensaios clínicos randomizados. As técnicas utilizadas na transição da dieta dos prematuros encontradas foram: sonda-dedo e seringa, copo e sonda-dedo, copo e mamadeira, colher e sucção não-nutritiva, sucção não-nutritiva, sucção não-nutritiva e estimulação oral, comportamento dos prematuros, cheiro do leite materno. Conclusão As técnicas evidenciadas permitiram a transição da dieta, em um período mais curto, reduzindo o tempo de internação, aumentando o ganho de peso e se mostraram seguras, desde que o prematuro tenha maturidade para ser realizada. Contudo, a mamadeira foi desaconselhada, pela ocorrência de episódios de dessaturação, aumento da frequência cardíaca e confusão de bico.

Resumen Objetivo Analizar las evidencias disponibles sobre la transición alimentaria de sonda orogástrica a lactancia materna directamente de la mama con prematuros internados en unidades hospitalarias. Métodos Revisión sistemática de la literatura con búsqueda en las bases de datos PubMed/MEDLINE, Web of Science, EMBASE, Scopus, Cochrane CENTRAL, CINAHL, con los siguientes criterios de inclusión: estudios experimentales, sin restricción temporal y en idioma portugués, español e inglés. La evaluación metodológica se realizó por medio de las herramientas Grading of Recommendations Assessment, Development and Evaluation (GRADE) y Revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0) y consistió en dos etapas: calidad metodológica y riesgo de sesgo de los estudios. Resultados Se identificaron 10 artículos, todos ensayos clínicos aleatorizados. Las técnicas utilizadas para la transición de la dieta de prematuros fueron: dedo-jeringa y jeringa, vaso y dedo-jeringa, vaso y mamadera, cuchara y succión no nutritiva, succión no nutritiva, succión no nutritiva y estimulación oral, comportamiento de los prematuros, olor de la leche materna. Conclusión Las técnicas observadas permitieron realizar la transición de la dieta en un período más corto, con reducción del tiempo de internación y mejor aumento de peso y demostraron ser seguras, siempre que el prematuro tenga madurez para realizarlas. No obstante, se desaconseja la mamadera por la presencia de episodios de desaturación, aumento de la frecuencia cardíaca y confusión tetina-pezón.

Abstract Objective To analyze the available evidence on the transition from orogastric tube feeding to breastfeeding directly from the breast with premature infants admitted to hospital units. Methods Systematic literature review with search in the following databases: PubMed/MEDLINE, Web of Science, EMBASE, Scopus, Cochrane CENTRAL, CINAHL, with the inclusion criteria: experimental studies, without temporal restrictions and in Portuguese, Spanish and English. The methodological assessment was carried out using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and Revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0) tools and consisted of two stages: methodological quality and the risk of bias of the studies. Results 10 papers were identified, all randomized clinical trials. The techniques used in transitioning the premature babies' diet were: finger tube and syringe, cup and finger tube, cup and bottle, spoon and non-nutritive sucking, non-nutritive sucking, non-nutritive sucking and oral stimulation, behavior of premature babies, and smell of breast milk. Conclusion The demonstrated techniques allowed the transition of the diet in a shorter period, reducing the length of hospital stay, increasing weight gain 1and proved to be safe, as long as the premature baby is mature enough to undergo the procedure. However, bottle feeding was not recommended due to the occurrence of episodes of desaturation, increased heart rate and nipple confusion.
