Risk factors for asphyxia neonatorum in full-term newborns at the University Hospital of Mahajanga Madagascar

Background: The aim of this survey was to study the risk factors associated with asphyxia neonatorum in full-term newborns in the neonatal unit in Child and Mother Complex at Androva Mahajanga Hospital.Methods: This was a retrospective case-control study conducted from August 2016 through September 2018.Results: The prevalence of neonatal asphyxia was 5.9%. Determinant factors for birth asphyxia were maternal education level below the tenth grade [OR=1.8 (1.2-2.6), p=0.003] especially if the mother was illiterate [OR=2.3 (1.5-3.6), p<0.001]; less than four prenatal care check-ups [OR=2.9 (1.7-4.9), p<0.001]; presence of maternal disease during pregnancy [OR=2.4 (1.6-3.6), p<0.001], arterial hypertension [OR=3.4 (1.6-7.2), p<0.001]; duration of labour ?24h [OR=2.1 (1.2-3.6); p=0.007] ; rupture of membranes ?12h [OR=2.9 (1.6-5.3), p<0.001]; labour outside teaching hospital [OR=21,1 (8,9-49,5), p<0,001]; home birth [OR=26.7 (3.6-199), p<0.001].Conclusions: Good monitoring of pregnancy, training of providers in neonatal resuscitation, and an increase in technical platforms could reduce the incidence of perinatal asphyxia.

Prevalencia de la alimentación exclusiva con lactancia materna en recién nacidos sanos / Prevalence of exclusive breastfeeding in the healthy newborn

Resumen Introducción: El mejor alimento para los niños durante los primeros seis meses de vida es la lactancia materna exclusiva (LME); se recomienda continuar con el amamantamiento junto con otros alimentos que complementen la alimentación hasta los dos años o más, mientras madre e hijo lo deseen. Los objetivos de este estudio fueron determinar la tasa de LME en los recién nacidos a término (RNT) en el momento del alta hospitalaria y a los 15 días y analizar los factores que influyen positivamente en la LME. Métodos: Estudio prospectivo en el que se reclutó una muestra de puérperas con hijos a término durante su ingreso. Se recogieron diferentes variables y se realizaron dos entrevistas para determinar el tipo de alimentación que estaban dando a sus hijos y si se mantenía a los 15 días del parto. Resultados: La tasa de LME al recibir el alta hospitalaria es muy inferior a lo recomendado. Ésta disminuye de manera importante a los 15 días del parto, cuando aumenta la lactancia artificial (LA). Al parecer, el parto eutócico, no presentar complicaciones en el parto, realizar lactancia materna (LM) precoz y el contacto piel con piel en el paritorio son factores favorecedores para establecer una buena LM en el alta hospitalaria. Conclusiones: A pesar de los esfuerzos de los profesionales, el porcentaje de recién nacidos (RN) alimentados con LME al nacer no alcanza las recomendaciones actuales.

Abstract Background: The best nourishment for infants during the first 6 months of life is exclusive breastfeeding. It is recommended along with other food to complement the diet until the child is 2 years old, as long as the mother and the child are willing to continue with it. The objectives of this study were to determine he exclusive breastfeeding rate in full term newborns at hospital discharge and 15 days later and to analyze the factors that positively affect the exclusive breastfeeding. Methods: A prospective study was conducted in which a sample of postpartum women with full term newborns was recruited during hospital admission. Different variables were compiled and two interviews were made to determine the kind of feeding they were giving their children and if it was maintained at 15 days of birth. Results: Exclusive breastfeeding rate at hospital discharge is much lower than recommended. It significantly decreases at 15 days of birth, increasing artificial feeding. It seems that having a vaginal birth, no complications giving birth, providing early breastfeeding and skin-to-skin contact in the delivery room are predisposing factors necessary to establish a good breastfeeding at hospital discharge. Conclusions: Despite the efforts of professionals, the percentage of newborns with exclusive breastfeeding at birth is not enough for the current recommendations.

Uso da sacarose para o alívio da dor: repercussão na amamentação materna durante a internação do recém-nascido a termo / Use of sucrose for pain relief: consequences on breastfeeding of fullterm newborns during hospitalization

Durante o período de internação, o recém-nascido (RN) é submetido a uma série de procedimentos dolorosos ou não, que podem incidir sobre o seu comportamento e sobre a confiança da mãe para o cuidado e para a amamentação materna. Temos como questionamento, se sacarose 25% que é oferecida como medida de alivio da dor em RN a termo internado em alojamento conjunto interfere negativamente na amamentação materna exclusiva durante a internação. Objetivo: Verificar a associação entre uso da sacarose 25% que é oferecida como medida de alívio dor aguda em RN a termo, e a amamentação materna durante a internação em alojamento conjunto. Métodos: Trata-se de um estudo observacional, transversal, descritivo e analítico. A amostra foi constituída por 215 binômios cujo nascimento e internação ocorreram entre os meses de Junho a Setembro de 2017 em uma maternidade do interior paulista intitulada "Amiga da Criança". Os binômios foram incluídos no estudo somente após autorização da mãe, com assinatura de um termo de consentimento livre e esclarecido. Os dados foram coletados por meio do prontuário e planilhas especificas. Os RN foram divididos em dois grupos: RN expostos e não expostos ao uso da sacarose durante a internação. Como houve diferença estatística entre os grupos para o tempo de internação, para analisar a influência do uso da sacarose na amamentação durante toda internação, foi feita uma relativização das variáveis de aleitamento materno pelo total de dias de internação do RN. As associações foram verificadas pelo teste "U" de Mann-Whitney, com valor de p significativo para ? <= 0,05. Resultado: Dos 215 RN estudados durante toda internação, 111 (51,6%) RN foram expostos ao uso da sacarose. Foi utilizado sacarose para 188 (60,1%) dos procedimentos dolorosos, sendo que a mesma foi usada associada a outros métodos como o colo em 18 (5,7%) e sucção não nutritiva 64 (20,4%) dos procedimentos. Somando-se o uso isolado ou em associação a outras medidas, a sacarose foi utilizada 270 (86,2%) vezes sendo a medida mais aplicada na prática clínica da maternidade. No grupo que utilizou sacarose as médias de frequência de mamadas, uso de copo, translactação, tempo médio por mamada e amamentação assistida foram respectivamente: 7,9, 0,2, 0,5, 11,4 e 1,0 . No grupo que não utilizou a sacarose, respectivamente, as a médias das mesmas variáveis foram de 8,7, 0,03, 0,06, 18,6 e 0,8. Houve diferença estatisticamente significativa entre os grupos para as variáveis de alimentação: frequência de mamada (p=0,03), utilização de copo (p=0,01), realização de translactação (p=0,00), tempo médio por mamada (p=0,00) e amamentação assistida (p=0,02). Conclusão: As associações dos dados encontrados comprovaram a hipótese do presente estudo, ou seja o uso da sacarose a 25% para alívio da dor aguda influenciou negativamente na amamentação materna do RN durante a internação, pois, o grupo de RN que recebeu esta substância adocicada durante os procedimentos de punção arterial, venosa e capilar, apresentou menor frequência de mamada, menor tempo médio por mamada, maior uso de complemento lácteo, mais necessidade de translactação e necessitou de mais amamentação assistida por um profissional de enfermagem, quando comparado ao grupo de RN não expostos a ela. Faz-se necessária a inclusão de medidas não farmacológicas com a participação da mãe em substituição à sacarose, uma vez que tratou-se de pesquisa em uma Maternidade Amiga da Criança

Introduction: During the period of hospitalization, full-term newborns (NB) undergo a series of painful procedures, which may affect his behavior and the mother's confidence in both taking care of and breastfeeding the baby. We question whether 25% sucrose, which is offered as a measure of pain relief in hospitalized NB infants, negatively interferes with exclusive mother's breastfeeding during hospitalization in rooming-in care. Aim: Verify the association between the use of 25% sucrose offered as pain relief in full-term newborns and exclusive mother's breastfeeding during hospitalization in shared rooms. Methods: This is a study based on observation, and it is transversal, descriptive and analytical study. The sample consisted of 215 binomials whose birth and hospitalization occurred between June and September of 2017 in a maternity hospital in the countryside of São Paulo, in a Child-Friendly Maternity. The binomials were included in the study only after authorization obtained from the mother, with the signing of a free and previously informed consent form. The data were collected through medical records and specific worksheets. The NB were divided into two groups: NB exposed and not exposed to the use of sucrose during hospitalization, respectively. There was a statistical difference between the groups due to the hospitalization period; thus, to analyze the influence of sucrose use on breastfeeding during all hospitalization, a relative analysis of the variables of breastfeeding by the total number of days of hospitalization of the newborn was made. Associations were verified by the Mann-Whitney "U" test, with a significant p value for ? <= 0.05. Results: From 215 NBs studied during all hospitalization, 111 (51.6%) were exposed to the use of sucrose. Sucrose was applied for 188 (60.1%) of the painful procedures, and it was used in association with other methods such as lap in 18 (5.7%) and non-nutritive suction in 64 (20.4%) of the procedures. Added the isolate use or in association with other measures, sucrose was used 270 (86.2%) times, being the most applied measure in clinical practice of maternity. In the sucrose group, the average of frequency of feeding, cupping, translactation, average time per feeding and assisted breastfeeding were respectively: 7.9, 0.2, 0.5, 11.4 and 1.0. In the nonsucrose group, the average of the same variables were 8.7, 0.03, 0.06, 18.6 and 0.8, respectively. There was a statistically significant difference between the groups for feeding variables: feeding frequency (p = 0.03), cup use (p = 0.01), translactation (p = 0.00), average time per feed (p = 0.00) and assisted breastfeeding (p = 0.02). Conclusion: The associations of the data confirmed the hypothesis of the present study, that is, the use of sucrose at 25% for acute pain relief influenced negatively the maternal breastfeeding of newborns during hospitalization, since the group of newborns who received this sugary substance during the venous and capillary puncture procedures, presented lower breastfeeding frequency, lower average time for breastfeeding, greater use of milky complement, higher need for translactation and required more breastfeeding assisted by a nursing professional, when compared to the NB group who was not exposed to it. It is necessary to include non-pharmacological measures with the participation of the mother instead of sucrose, since it was a research in a Child-Friendly Maternity

Morbimortalidad del recién nacido a término precoz en el hospital Hipólito Unanue de Tacna durante los años 2000 a 2014 / Morbimortality of early term newborns at Tacna's Hipólito Unanue hospital during the years 2000 to 2014

Objetivo: Determinar la frecuencia, tasa de cesárea y riesgos de morbimortalidad del recién nacido a término precoz (RNTP). Material y métodos: Estudio observacional, retrospectivo, analítico. Se incluyó a neonatos únicos vivos a término, nacidos en el hospital Hipólito Unanue de Tacna durante los años 2000 a 2014 (n=45332). Se comparó a los nacidos a termino precoz de 37 a 38 6/7 semanas (n=11276), y los nacidos a termino completo de 39 a 41 6/7 semanas (n=34056). Se utilizó frecuencia y tasa por 100 nacidos vivos, odds ratio (OR) con intervalos de confianza al 95% (IC 95%), regresión logarítmica y prueba "t" para muestras independientes. Se utilizó la base de datos del Sistema Informático Perinatal. Resultados: La frecuencia de nacidos a término precoz fue 22,5 por 100 nacidos vivos, con un crecimiento logarítmico significativo (p=0,03). Representó 24,9% de todos los recién nacidos a término. La tasa de cesárea se incrementó de 31,2% a 51,1% y su crecimiento fue similar al de los término completo. Se asoció al RNTP con mayor probabilidad de tener bajo peso al nacer (OR:5,33; IC 95%: 4,50-6,30), ser pequeño para la edad gestacional (OR:3,14; IC 95%: 2,69- 3,66), nacer por cesárea (OR: 3,15; IC 95%: 3,01-3,29), tener estancia hospitalaria de 3 días a más (OR: 1,46; IC 95%: 1,39-1,54), morbilidad respiratoria (OR: 1,81; IC 95%: 1,38-2,37) como neumonía (OR:3,02; IC 95%: 1,70-5,38), membrana hialina (OR: 4,17; IC 95%: 1,56-11,33) y taquipnea transitoria (OR: 2,95; IC 95%: 1,79-4,85); y malformaciones congénitas (OR: 1,46; IC 95%: 1,17-1,82), hiperbilirrubinemia (OR: 1,23; IC 95%: 1,02-1,49) y mortalidad neonatal (OR: 2,17; IC 95%: 1,45-3,23). Conclusión: La frecuencia de recién nacidos a término precoz en el hospital Hipólito Unanue de Tacna se incrementó en los últimos 15 años y se asoció a mayor riesgo de problemas respiratorios y mortalidad neonatal

Objective: To determine the frequency, cesarean section rate and morbidity and mortality risks for early term newborns. Material and methods: Non-experimental, cross-sectional study. We included single term live neonates born in Hipolito Unanue Hospital in Tacna from 2000 to 2014 (n= 45332). Early term newborns from 37 to 38 6/7 weeks (n= 11276), were compared with full term newborns from 39 to 41 6/7 weeks (n= 34056). We used frequencies and rates per 100 live births, odds ratios (OR) with 95% confidence intervals (95% CI), logarithmic regression and "t" test for independent samples. The Perinatal Computer System database was used. Results: The frequency of preterm infants was 22.5 per 100 live newborns, with a significant logarithmic growth (p= 0.03). This accounted for 24.9% of all full term newborns. The cesarean section rate increased from 31.2% to 51.1% and its growth was similar to that of full term newborns. It was associated with a higher risk of low birth weight (OR: 5.3; 95% CI:4.5-6.3), small for gestational age babies (OR: 3.14; 95% CI: 2.69-3.66), being born by cesarean section (OR: 3.15; 95% CI: 3.01-3.29), hospital stay of 3 days or more (OR: 1.46; 95% CI: 1.39-1,54), respiratory morbidities (OR: 1.81; 95% CI: 1.38-2.37), such as pneumonia (OR: 3.02; 95% CI: 1.70-5.38), hyaline membrane (OR: 4.17; IC 95% CI: 1.56-11.33), and transient tachypnea (OR: 2.95; 95% CI: 1.79-4.85); and congenital malformations (OR: 1.46; IC 95% CI: 1.17-1.82), hyperbilirubinemia (OR: 1.23; 95% CI: 1.02-1.49), and neonatal mortality (OR: 2.17; 95% CI: 1.45-3.23). Conclusion: The frequency of early term newborns in Hipolito Unanue Hospital in Tacna increased in the last 15 years, and it was associated with an increased risk of respiratory problems and neonatal mortality

Thyroid abnormalities in term infants with fungal sepsis / Alterações tireoidianas no recém-nascido de termo com sepse fúngica

Summary Objective: To describe thyroid alterations in term newborns (TNB) with fungal sepsis during NICU hospitalization. Method: The study included six TNB that during the clinical and laboratory manifestations of sepsis with positive cultures for fungus showed changes in thyroid hormones, called low T3 syndrome and low T3-T4 syndrome. TNB that could present hormonal changes caused by disease as those born to mothers with thyroid disease, or who had perinatal asphyxia and major surgeries were excluded. Results: Of six TNB with fungal sepsis, five had positive culture for Candida albicans and one had positive culture for Candida tropicalis. Low T3 syndrome was observed in two TNB (50%), while T3-T4 syndrome was observed in other two (100%). The four children progressed to septic shock. Conclusion: Fungal sepsis is becoming more common among newborns admitted to NICU. Thyroid insufficiency could be a marker of disease severity with possible need for hormone supplementation.

Resumo Objetivo: descrever as alterações tireoidianas em recém-nascidos de termo (RNT) que apresentaram sepse fúngica durante internação na UTI neonatal. Método: foram incluídos seis RNT que, durante as manifestações clínicas e laboratoriais de sepse, com culturas positivas para fungo, apresentaram alterações dos hormônios tireoidianos, denominadas síndrome do T3 baixo e síndrome do T3 e T4 baixo. Foram excluídos RNT que apresentaram alteração hormonal por doença, como RNT filhos de mães com doença tireoidiana, asfixia perinatal e cirurgias de grande porte. Resultados: dos seis RNT com sepse fúngica, cinco apresentavam cultura positiva para Candida albicans e um para C. tropicalis. A síndrome do T3 baixo foi observada em duas crianças (50%) e a do T3 e T4 baixo em dois RN (100%). As quatro crianças evoluíram com choque séptico. Conclusão: a sepse fúngica é cada vez mais frequente nos recém-nascidos internados em UTI neonatal. A insuficiência tireoidiana pode vir a ser marcadora de gravidade da doença, e a suplementação hormonal pode ser necessária.

Nonthyroidal illnesses syndrome in full-term newborns with sepsis

ABSTRACT Objective To assess hormonal changes in nonthyroidal illness syndrome (NTIS) in full-term newborns (NT) with sepsis. Materials and methods We included 28 NT with sepsis divided into 2 groups according to the time of normalization of serum and clinical indicators of infection: group A(A), 16 NT with improvement in up to 8 days; and group B(B), 12 NT improvement after 8 days. Among the 28 NT, 15 NT progressed to septic shock, with 5 NT group A and 10 NT in group B. NT were excluded when they showed severe sepsis and asphyxia, and congenital malformations, as well as those whose mothers had thyroid disease and IUGR. Results 17 NT (60.7%) presented NTIS. Low T3 was observed in NTIS in 10 NT (58.8%), and low T4 and T3 in 5 NT (29.5%), all of them with septic shock. Two NT showed mixed changes (11.7%). After sepsis was cured, there was no hormonal change, except in 3 NT. Administration of dopamine, furosemide, and corticosteroids did not affect the results. Conclusions This study indicates that nonthyroidal illness syndrome may be transiently present during sepsis in full-term newborns, especially in cases of prolonged sepsis. Low T3 can occur without changes in reverse T3 (different from adults), and low T4 and T3 occur mainly in patients with septic shock. Arch Endocrinol Metab. 2015;59(6):528-34.

Clinical Characteristics of Acute Respiratory Tract Infections in Full-Term Newborns without Risk Factors

PURPOSE: This study evaluated the characteristics and symptoms of full-term newborns without risk factors who were diagnosed with acute lower respiratory tract infections (ALRI). METHODS: Nasopharyngeal aspirates were obtained from 72 full-term newborns to 30 days of age who were diagnosed with ALRI from September 2011 to November 2013 and analyzed by multiplex real time-polymerase chain reaction (RT-PCR). RESULTS: Viruses were detected in 60 newborns (83.3%). Single viruses were observed in 56 newborns (77.7%). The most commonly detected viral agent was respiratory syncytial virus (RSV) (63.8%), followed by parainfluenza virus (6.9%), rhinovirus A/B (4.1%), and human coronavirus (2.7%). Clinical diagnoses of ALRI in newborns with a single virus included pneumonia (66.07%), bronchiolitis (30.43%), bronchitis (5.35 %), and croup (1.79%). There were no differences in epidemiological characteristics between RSV and other viruses. However, newborns diagnosed with RSV had prolonged hospitalizations and significantly increased respiratory rates. CONCLUSION: Respiratory viruses, especially RSV, are pivotal causes of ALRI in newborns. Further, studies on RSV severity and vaccination are necessary to reduce hospitalization and mortality of full-term infants.

Assessment of the central corneal thickness and intraocular pressure in premature and full-term newborns.

Purpose: To assess the central corneal thickness (CCT) and intraocular pressure (IOP) in premature and full-term newborns. Materials and Methods: In this study, we evaluated measurements of CCT and IOP in 45 premature and 45 full-term newborns. IOP was determined with topical anesthesia using a Tono-Pen AVIA, applanation tonometer and a wire lid retractor in premature newborns undergoing screening for retinopathy. Full-term newborns were used as a control group. CCT was determined with a portable pachymeter after IOP measurements had been made in both groups. Because there was high correlation of CCT and IOP between right and left eyes, only the right eye data were used for further analyses. Results: The mean gestational age was 31.5 ± 2.7 weeks (ranging 25-35 weeks) and the mean age at measurement after birth was respectively 36.3 ± 0.9 weeks (ranging 33-37 weeks) in premature newborns and 38.2 ± 0.7 weeks (ranging 38-41 weeks) and 42 ± 2.2 weeks (ranging 39-46 weeks) in full-term newborns. The mean IOP was 16.2 ± 2.7 mmHg (ranging 10-22 mmHg) in premature and 16.6 ± 2.3 mmHg (ranging 10-22 mmHg) in full-term newborns. The mean CCT was found 600 ± 50 μm (ranging 515- 790 μm) in the premature group and 586 ± 48 μm (ranging 475-730 μm) in the full-term group. Mean CCT was greater in premature newborns than in full-term newborns, but the diff erence between groups was not statistically signifi cant (P = 0.7). Mean IOP measurement in two groups was found very similar and the diff erence also was not statistically signifi cant (P = 0.27). There was no correlation between IOP and CCT, gestational age, gestational weight, age at measurement, weight at measurement neither right nor left eye in both groups in multiple regression analysis. Conclusion: We found that premature infants have slightly thicker corneas but no high IOP measurements than full-term newborns. It could be concluded that in premature at the mean gestational age of 36 weeks CCT is not diff erent from that of full-term newborns.

Comparação entre as células-tronco de sangue de cordão umbilical de neonatos prematuros e nascidos a termo: uma revisão / Comparison between preterm and full-term newborn umbilical cord blood stem cells: a review

As células-tronco são células capazes de gerar diferentes tipos celulares. Entre as fontes de células-tronco encontra-se osangue de cordão umbilical que apresenta um grande número de progenitores hematopoéticos. Essa fonte vem sendo amplamente utilizada em transplantes devido a diversas vantagens, entre elas, a imediata disponibilidade, beneficiando pacientes com doenças hematológicas e imunológicas. Para o sucesso dos transplantes, há a necessidade de se considerar a freqüência das células-tronco nas amostras de sangue de cordão umbilical. Marcadores celulares específicos como a presença da molécula CD34 e a ausência de CD38 indicam o grau de imaturidade das células-tronco hematopoéticas e, conseqüentemente, a sua grande capacidade de proliferação e diferenciação celular. Existem diferenças quanto à freqüência das células-tronco no sangue de cordão umbilical entre neonatos nascidos a termo e prematuros. Essas diferenças podem ser importantes na escolha das amostras armazenadas nos bancos de sangue de cordão umbilical a serem utilizadas nos transplantes de células-tronco. Além disso, as pesquisas com células-tronco têm mostrado grande capacidade de proliferação e diferenciação em vários tecidos. O estudo das células-tronco pode ser a resposta para o tratamento de doenças cardíacas, neurológicas e imunológicas de inúmeros pacientes e, talvez, o primeiro passo para a cura.

Stem cells are cells that have the ability to give rise to different cell types. Among the sources of stem cells, there is the umbilical cord blood, which has a great number of hematopoietc progenitors. This source has been widely used in transplants owingto its advantages like, for example, immediate availability, improving patients with immunological and hematological diseases. In order for the transplant to be successful, it is necessary to consider the stem cell frequency within the samples of the umbilical cord blood. Specific markers like the presence of CD34 molecule and the absence of CD38 indicates the immature level of hematopoietic stemcells and consequently their ability of cellular proliferation and differentiation. There are differences between the cellular frequency in umbilical cord blood from preterm and term newborn. These differences might be important in order for finding a sample stored atumbilical cord blood banks for the transplant. Nevertheless, research using stem cells has attempted that these cells have a great capacity of proliferation and differentiatin into many tissues. Stem cell research offers hope for the treatment of cardiac, neurological and imunological diseases of countless patients and, perhaps, the first step to the cure.

Risk factors and clinical characteristics of necrotizing enterocolitis in full-term newborns / 소아과

PURPOSE: The purpose of this study was to determine those factors which could contribute to the development of necrotizing enterocolitis(NEC) in fullterm. METHODS: We retrospectively reviewed the medical record of 20 full-terms with NEC(> or = modified Bell's staging criteria IIa) who were admitted to the Neonatal Intensive Care Unit of Il Sin Christian hospital from January 1998 through July 2005, and for each case, the next 2 healthy newborns were matched as controls. RESULTS: Mean gestational age and birth weight in the fullterm with NEC group was 38.42 weeks and 2,915 g; in the healthy fullterm without NEC group, it was 38.61 weeks and 3,148 g. When compared with the control group, NEC infants had a significantly higher frequency of chorioamnionitis, protracted diarrhea. As for Apgar score at 1 min <7, respiratory problem, congenital heart disease. there were no differences in frequency of preeclampsia, maternal diabetes, maternal drug abuse, meconium-stained amniotic fluid, polycythemia or exchange transfusion. CONCLUSION: Most of these full term infants have a predisposing factor before developing NEC. Our study suggested that NEC in fullterm infants was significantly associated with protracted diarrhea, and congenital heart disease.
