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).

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).

Abstract Objective To describe the beginning, duration, location and who makes skin-to-skin contact in Brazilian neonatal units. Methods This is a descriptive, longitudinal multicenter study, carried out from May 2018 to March 2020, in five reference neonatal units for Kangaroo Mother Care in Brazil, which included newborns weighing up to 1,800 grams. Maternal and newborn characteristics were collected from medical records and interviews. Skin-to-skin contact was recorded on cards attached to the bed, filled in by the team and fathers. Analysis occurred through descriptive statistics. Results We included 405 newborns, 51.4% male, median gestational age of 31.4 weeks and birth weight of 1,412 grams. Regarding skin-to-skin contact time, the median daily contact frequency was 1.5 times (IQR: 1.2 - 2.4), the time/day was 147 min/day (IQR: 106.7 - 263.0) and the first contact at five days of life (IQR:4.0-8.0). The longest contact time/day was performed by mothers, with a median of 137.8 minutes per day (IQR:95.6-232.1), and the second stage of kangaroo Mother Care, kangaroo Intermediate Care Unit, was the place where contact was performed for the longest time, with a median of 184.4 minutes per day (IQR:124.7-455.4). Conclusion In the units assessed, skin-to-skin contact is practiced intermittently, a few times a day, predominantly by mothers and with longer exposure time in the second stage. It is necessary to seek ways that allow more encounters between mother/father-child and that gives conditions of greater permanence of fathers in the hospital. beginning duration skintoskin skin study 201 2020 Brazil 1800 1 800 1,80 grams interviews Skintoskin Skin bed statistics 40 514 51 4 51.4 male 314 31 31. 1412 412 1,41 15 5 1.

Abstract Objective: The objective of this study was to evaluate the effect of Kangaroo Position (KP) in microcirculation (MC) of the flexor muscles of preterm newborns. Method: A controlled clinical trial was conducted in the city of Recife, Brazil, with 26 preterm children randomized in the Kangaroo Group (13) and in the Control Group (13). Assessments of blood flow, temperature, and tissue oxygen saturation (SO2) were made at two different times and in the biceps brachii muscle and hamstrings muscle group: before the KP and after 24 h of KP. In the Control Group, the registrations were performed at the times corresponding to those of the Kangaroo Group. The mean values among the times were analyzed by paired t-test for repeated measures. The clinical trial was recorded in Clinical Trials (NCT03611088). Results: In the Kangaroo Group there was an increase in tissue temperature and blood flow at the time evaluation periods (p < 0.05). In the control group, there was no statistical difference between the recording moments hamstring muscles group, but in the biceps brachii, there was a reduction in mean blood flow (p = 0.023). Conclusion: In conclusion, the KP has effects on the microcirculation of the flexor muscles of preterm newborns.

ABSTRACT OBJETIVE To understand the role of exposure to skin-to-skin contact and its minimum duration in determining exclusive breastfeeding at hospital discharge in infants weighing up to 1,800g at birth. METHODS A multicenter cohort study was carried out in five Brazilian neonatal units. Infants weighing ≤ 1,800g at birth were eligible. Skin-to-skin contact time was recorded by the health care team and parents on an individual chart. Maternal and infant data was obtained from maternal questionnaires and medical records. The Classification Tree, a machine learning method, was used for data analysis; the tree growth algorithm, using statistical tests, partitions the dataset into mutually exclusive subsets that best describe the response variable and calculates appropriate cut-off points for continuous variables, thus generating an efficient explanatory model for the outcome under study. RESULTS A total of 388 infants participated in the study, with a median of 31.6 (IQR = 29–31.8) weeks of gestation age and birth weight of 1,429g (IQR = 1,202–1,610). The exclusive breastfeeding rate at discharge was 61.6%. For infant’s weighting between 1,125g and 1,655g, exposed to skin-to-skin contact was strongly associated with exclusive breastfeeding. Moreover, infants who made an average > 149.6 min/day of skin-to-skin contact had higher chances in this outcome (74% versus 46%). In this group, those who received a severity score (SNAPPE-II) equal to zero increased their chances of breastfeeding (83% versus 63%). CONCLUSION Skin-to-skin contact proved to be of great relevance in maintaining exclusive breastfeeding at hospital discharge for preterm infants weighing 1,125g–1,655g at birth, especially in those with lower severity scores.

Resumo Objetivo: Verificar a influência de curto prazo da Posição Canguru (PC) sobre a atividade eletromiográfica de recém-nascidos prematuros. Método: Foi feito um estudo clínico em um setor da Unidade do Método Mãe Canguru (cuidado secundário e terciário) na cidade de Recife, com 44 neonatos prematuros randomizados em grupos de Intervenção (n = 21) e Controle (n = 23). A Posição Canguru foi feita por meio de uma faixa que apoia o recém-nascido de bruços contra o tórax do adulto, na posição vertical e vestido com poucas peças de roupa, mantém o contato pele a pele com a mãe. Foi usada a Eletromiografia Superficial para investigar a atividade muscular dos bíceps braquiais e músculos isquitobiais. A randomização dos grupos foi feita com o software R (versão 3.3.1)®. Os registros da eletromiografia foram feitos em três momentos: antes da PC e após uma e duas horas da Posição Canguru. No Grupo de Controle, os registros foram feitos nos momentos correspondentes àqueles do Grupo do Método Mãe Canguru. Os valores médios da atividade eletromiográfica entre esses momentos foram analisados pela análise de variância (Anova) de medidas repetidas e por um teste de Kruskal-Wallis. O ensaio clínico foi registrado no Clinical Trials (NCT02849665 – 28/07/2016). Resultados: No Grupo do Método Mãe Canguru (n = 21), houve variação dos valores da atividade eletromiográfica entre os três momentos de registro de atividade dos bíceps braquiais e dos músculos isquitobiais. No Grupo de Controle (n = 23), não houve diferença estatística entre os momentos de registro. Conclusões: A PC aumenta a atividade eletromiográfica de curto prazo dos músculos bíceps braquiais e isquitobiais.

Abstract Objective: To verify the short-term influence of the kangaroo position (KP) on the electromyography activity of preterm newborns. Method: A clinical study was conducted in a kangaroo unit sector (secondary and tertiary care) in the city of Recife, Brazil, with 44 preterm infants randomized to intervention (n = 21) and control (n = 23) groups. The KP was performed through a band that supports the newborn against the adult's thorax, in a prone and vertical position, and infants were dressed with few pieces of clothes, thus keeping skin-to-skin contact with the mother. Surface electromyography was used to investigate the muscle activity of the biceps brachii and hamstrings. The randomization of the groups was performed by the program R® (v. 3.3.1). The electromyography registrations were made at three different times: before the KP and after one and two hours of KP. In the control group, the registrations were performed at the times corresponding to those of the intervention group. The mean values of the electromyography activity among the times were analyzed by ANOVA for repeated measures and the Kruskal–Wallis test. The clinical trial was recorded in ClinicalTrials.gov (NCT02849665 - 07/28/2016). Results: In the intervention group (n = 21), there was a variation of the electromyography activity values between the three recording moments for both the biceps brachii and hamstrings. In the control group (n = 23), there was no statistical difference between the recording moments for both. Conclusions: The KP increases the short-term electromyographic activity of the biceps brachii and hamstrings.

Resumo Objetivo: Caracterizar o frênulo lingual de recém-nascidos a termo, utilizando dois protocolos diferentes e verificar a relação do frênulo lingual com o aleitamento materno. Método: A amostra não probabilística foi constituída por 449 binômios mãe/bebê. Para a avaliação anatomofuncional do frênulo, utilizou-se o protocolo de avaliação do frênulo lingual para bebês “Teste da Linguinha” e o Bristol Tongue Assessment Tool. A mamada foi avaliada com o protocolo proposto pelo UNICEF. Foram criados escores (bom, regular, ruim) para avaliar cada aspecto da mamada a ser observada. Os resultados foram analisados através de estatísticas descritivas e inferenciais e testes de associação (Qui-quadrado de Pearson e Exato de Fisher). Resultados: O estudo mostrou que 14 bebês apresentaram alteração de frênulo lingual, nos quais três com dificuldade durante a sucção, necessitando de frenotomia na primeira semana de vida e 11 sem dificuldades durante a amamentação. Quanto à avaliação da mamada, 410 binômios mãe/bebê apresentaram o escore bom, 36 regular e 3 ruim. Houve associação estatisticamente significativa entre o protocolo “Teste da Linguinha” e amamentação (p = 0,028) e entre o protocolo Bristol Tongue Assessment Tool e amamentação (p = 0,028). Conclusão: Alterações no frênulo lingual estão associadas a interferências na qualidade da amamentação, sendo importante a avaliação do frênulo lingual em recém-nascidos.

Abstract Objective: To characterize the lingual frenulum of full-term newborns using two different protocols and to assess the association of the lingual frenulum with breastfeeding. Methods: This non-probabilistic sample consisted of 449 mother/baby binomials. For the anatomo-functional evaluation of the frenulum, the Neonatal Tongue Screening Test and the Bristol Tongue Assessment Tool were used for the evaluation of the lingual frenulum. Breastfeeding was evaluated using the protocol proposed by UNICEF. Scores were created (good, fair, poor) to evaluate every aspect of the breastfeeding to be observed. The results were analyzed through descriptive and inferential statistics and association tests (Pearson's chi-squared and Fisher's exact test). Results: The study showed that 14 babies had a lingual frenulum alteration, of whom three had difficulties during suction, requiring frenotomy in the first week of life, whereas 11 had no difficulties during breastfeeding. Regarding the breastfeeding evaluation, 410 mother/baby binomials had good, 36 regular, and three had bad scores. There was a statistically significant association between the tongue-tie test protocol and breastfeeding (p = 0.028) and between the Bristol Tongue Assessment Tool protocol and breastfeeding (p = 0.028). Conclusion: Alterations in the lingual frenulum are associated with interferences in the quality of breastfeeding and thus, evaluation of the lingual frenulum in newborns is important.
