ABSTRACT

RESUMO Objetivo descrever o processo de construção e estratégias de implementação de um bundle para alívio da dor durante a punção arterial do bebê hospitalizado. Métodos estudo de abordagem qualitativa feito em uma unidade de terapia intensiva neonatal, por meio de rodas de conversa realizadas com a equipe de enfermagem. A coleta dos dados ocorreu de fevereiro a maio de 2019. Resultados os encontros levaram à construção de um bundle composto por quatro itens, formatado ludicamente e que deveria ser anexado à incubadora, previamente à realização da punção. Conclusões e Implicações para a prática o processo estimulou a reflexão crítica acerca da própria prática e os profissionais referiram ao uso do bundle como algo possível dentro da unidade, mediante um planejamento para sua inclusão na rotina assistencial. O estudo é pioneiro e apresenta caráter de inovação ao utilizar o bundle para aliviar algo multifacetado como a dor no período neonatal. Apesar de ser algo criado especificamente para a punção arterial, o mesmo pode ser aplicado em demais procedimentos que potencialmente geram dor aguda, uma vez que o foco principal é sempre minimizar o desconforto sentido pelo bebê.

ABSTRACT

Objetivo: analisar o número de procedimentos dolorosos agudos e manejo da dor em recém-nascidos pré-termo em uma unidade neonatal. Método: estudo descritivo, transversal. Teve como campo uma unidade neonatal de uma instituição pública de saúde. Os participantes da pesquisa foram recém-nascidos abaixo de 35 semanas. Resultados: foram incluídos 17 recémnascidos. Foi quantificado um total de 729 procedimentos dolorosos. Em média foram realizados 42,9 procedimentos por recém-nascido durante os primeiros 14 dias de vida, sendo aproximadamente três procedimentos realizados por bebê no serviço diurno. Dentre os procedimentos, o mais frequente foi a punção de calcâneo (23,9%). O manejo predominante foi a contenção facilitada (32,7%). A (re)inserção de pronga foi o segundo procedimento mais realizado. Conclusões: O estudo permitiu apreender que o manejo da dor no recém-nascido pré-termo internado em uma unidade neonatal ainda é um desafio

ABSTRACT

O objetivo do estudo foi procurar proteínas de fase aguda que possam indicar sinais de maturação no neonato prematuro, por meio da quantificação sérica delas. Identificou-se a imunoglobulina A, a ceruloplasmina, a haptoglobina, a glicoproteína ácida, a transferrina, a albumina e as imunoglobulinas G de cadeias leve e pesada, pela comparação do perfil dos proteinogramas de cordeiros nascidos a termo com os prematuros submetidos a diferentes protocolos terapêuticos, a fim de estimular a atividade respiratória. Constituíram-se seis grupos: PN (n= 9): nascidos de parto normal; CN (n= 7): nascidos de cesariana em tempo normal de gestação; CP (n= 6): nascidos de cesariana prematura sem nenhum tipo de tratamento; DEX (n= 9): prematuros cujas mães receberam dexametasona pré-parto; SURF (n= 6): prematuros tratados com surfactante; e DEXSURF (n= 6): prematuros tratados com surfactante cujas mães receberam dexametasona pré-parto. As avaliações foram realizadas nos momentos imediatamente após o nascimento (M0), após 24 (M24) e após 48 horas (M48). As amostras foram processadas por meio de eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE). A albumina, as imunoglobulinas e a proteína total dos cordeiros tiveram elevação após a ingestão de colostro. Maiores valores séricos de transferrina são referentes a maior período gestacional, podendo essa proteína ser utilizada como marcador de maturação neonatal.(AU)


The aim of this study was to search for acute phase proteins that could indicate signs of maturation in the premature neonate by quantifying them in serum. Immunoglobulin A, ceruloplasmin, haptoglobin, acid glycoprotein, tranferrin, albumin, light and heavy chain immunoglobulin G were quantified, comparing the profile of proteinograms from term to preterm lambs submitted to different protocols that stimulate respiratory activity. Six groups were used: PN (n= 9): born from normal birth; CN (n= 7): born from caesarean section at normal time of gestation; CP (n= 6): born from premature cesarean without any type of treatment; DEX (n= 9) preterm whose mothers received prepartum dexamethasone; SURF (n= 6) preterm treated with surfactant; DEXSURF (n= 6): preterm treated with surfactant whose mothers received prepartum dexamethasone. The evaluations were performed immediately after birth (M 0), after 24 and 48 hours (M 24 and M 48). Samples were processed with sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Albumin, immunoglobulins, and serum total protein of the lambs were elevated, after colostrum ingestion. Higher serum transferrin values refer to a longer gestational period, and this protein may be used as a marker of neonatal maturation.(AU)

ABSTRACT

SUMMARY OBJECTIVE: We measured the level of pH gases in premature infants at birth, and examined the relationship between brain ultrasonography on the third and seventh day after birth. A case-control study conducted at the Neonatal Intensive Care Unit (NICU) of Shahid Akbar Abadi Hospital, Iran, during the years 2016-2017. METHODS: All premature infants who were admitted to NICU were enrolled in the current study. At birth, a blood gas sample was taken from the umbilical cord of the infants. On the third and seventh day after birth, an ultrasound of the brain of each neonate was performed by a radiologist. The umbilical cord was evaluated for blood gases in 72 neonates (mostly boys). RESULTS: Sixty-six newborns had normal sonography, and 16.7% (12 cases) had anomalies. A total of 75% of the 8 infants with intravenous bleeding were girls, which were significantly different from those in the non-hemodynamic group (62.5% male) (P 0.049). However, the type of delivery, mean weight, height, head circumference, the circumference of the chest, and Apgar score did not differ between the two groups. Mean pH, HCO3- and PCO2 in umbilical cord blood gas samples were not significantly different between the two groups with or without intraventricular hemorrhage (IVH). Although it was not related to gender and type of delivery in newborns CONCLUSION: Blood gases do not help in determining the occurrence of IVH in infants. Nevertheless, it is associated with immaturity and fetal age.


RESUMO OBJETIVOS: Medimos o nível de gases de pH em bebês prematuros, no nascimento dos neonatos, e examinamos a relação entre a ecografia cerebral no terceiro e no sétimo dia após o nascimento. Um estudo de casos e controles realizados na Unidade de Cuidados Intensivos Neonatais (UCIN) do Hospital Shahid Akbar Abadi durante os anos de 2016-2017, Irã. MÉTODOS: Todos os recém-nascidos prematuros que deram entrada na UCIN foram inscritos no estudo atual. Ao nascer, foi retirada uma amostra de gás em sangue, do sangue do cordão umbilical dos bebês. No terceiro e sétimo dia após o nascimento, um radiologista realizou uma ecografia do cérebro de cada neonato. O cordão umbilical foi avaliado para detectar gases no sangue em 72 neonatos (em sua maioria do sexo masculino). RESULTADOS: Sessenta e seis recém-nascidos tinham ecografia normal e 16.7% (12 casos) tinham anomalias. 75% das 8 crianças com hemorragia intravenosa eram meninas, que foram significativamente diferentes das do grupo não hemodinâmico (62.5% homens) (P.0.049). Contudo, o tipo de parto, o peso médio, a altura, o perímetro cefálico, a circunferência do tórax e a pontuação de Apgar não foram diferentes entre os grupos. O pH médio, HCO3 e PCO2 nas amostras de gás no sangue do cordão umbilical não foram significativamente diferentes entre dois grupos com ou sem hemorragia intraventricular (Hiv). Apesar de não estar relacionado com o gênero e o tipo de parto em recém-nascidos. Conclusão: os gases sanguíneos não ajudam a determinar o aparecimento de Hiv nos bebês. Contudo, está associado com a imaturidade e idade fetal.

ABSTRACT

ABSTRACT Objective: The present study evaluated the anthropometric and metabolic profiles of preterm infants (PT) born from mothers with urinary tract infections (UTI) and mothers with hypertensive disorders (HD). Method: This was a longitudinal prospective study conducted between May 2015 and August 2016. First, 59 mothers with premature birth were included; after excluding 29 mothers, two subgroups were created: UTI-mothers (n=12) and HD-mothers (n=18). The anthropometric and metabolic variables of mothers and their respective PT were analyzed at birth and at 6 months of corrected age (CA). Results: Plasma triglyceride levels were higher among HD-mothers and their respective PT in comparison with UTI-mothers and their PT at 6 m of CA. Conclusion: Plasma triglyceride level is an important metabolic biomarker in HD-mothers resulting in higher triglyceride levels among PT at the CA of 6 m, suggesting an early programming effect of maternal hypertension.


RESUMEN Objetivo: El estudio evaluó los perfiles antropométricos y metabólicos de prematuros (PT) nacidos de madres con infección del tracto urinario (ITU) y de madres con desórdenes hipertensivos (DH). Método: Estudio longitudinal-prospectivo, realizado entre mayo de 2015 y agosto de 2016. Inicialmente fueron incluidas 59 madres con partos prematuros; luego de 29 exclusiones, fueron separadas en dos grupos: madres-ITU (n=12) y madres-DH (n=18). Las variables antropométricas y metabólicas fueron analizadas en las madres y en sus PT al nacimiento y a los 6 meses de edad corregida (EC). Resultados: Los niveles de triglicéridos plasmáticos fueron mayores en madres-DH y en sus PT, en comparación con las madres-ITU y sus PT a los 6 meses de EC. Conclusión: Los niveles de triglicéridos plasmáticos constituyen un importante biomarcador metabólico en madres-DH, determinando valores elevados de triglicéridos en PT de 6 meses de EC, sugiriendo de modo precoz un efecto programador de hipertensión maternal.

ABSTRACT

Objective: To assess the impact of respiratory therapy with the expiratory flow increase technique on cerebral hemodynamics of premature newborns. Methods: This is an intervention study, which included 40 preterm infants (≤34 weeks) aged 8-15 days of life, clinically stable in ambient air or oxygen catheter use. Children with heart defects, diagnosis of brain lesion and/or those using vasoactive drugs were excluded. Ultrasonographic assessments with transcranial Doppler flowmetry were performed before, during and after the increase in expiratory flow session, which lasted 5min. Cerebral blood flow velocity and resistance and pulsatility indices in the pericallosal artery were assessed. Results: Respiratory physical therapy did not significantly alter flow velocity at the systolic peak (p=0.50), the end diastolic flow velocity (p=0.17), the mean flow velocity (p=0.07), the resistance index (p=0.41) and the pulsatility index (p=0.67) over time. Conclusions: The expiratory flow increase technique did not affect cerebral blood flow in clinically-stable preterm infants.


Objetivo: Avaliar a repercussão da fisioterapia respiratória com a técnica de aumento do fluxo expiratório sobre a hemodinâmica cerebral de recém-nascidos prematuros. Métodos: Estudo de intervenção no qual foram incluídos 40 neonatos prematuros (≤34 semanas) com 8-15 dias de vida, clinicamente estáveis em ar ambiente ou em uso de cateter de oxigênio. Foram excluídas crianças com malformações cardíacas, diagnóstico de lesão cerebral e/ou em uso de drogas vasoativas. Exames de ultrassonografia com avaliação por dopplerfluxometria cerebral foram feitos antes, durante e depois da sessão de aumento do fluxo expiratório, que durou cinco minutos. Foram avaliadas as velocidades de fluxo sanguíneo cerebral e os índices de resistência e pulsatilidade na artéria pericalosa. Resultados: A fisioterapia respiratória não alterou significativamente a velocidade de fluxo no pico sistólico (p=0,50), a velocidade de fluxo diastólico final (p=0,17), a velocidade média de fluxo (p=0,07), o índice de resistência (p=0,41) e o índice de pulsatilidade (p=0,67) ao longo do tempo. Conclusões: A manobra de aumento do fluxo expiratório não afetou o fluxo sanguíneo cerebral em recém-nascidos prematuros clinicamente estáveis.

ABSTRACT

Objective: To evaluate phenylalanine plasma profile in preterm newborns fed different human milk diets. Methods: Twenty-four very-low weight preterm newborns were distributed randomly in three groups with different feeding types: Group I: banked human milk plus 5% commercial fortifier with bovine protein, Group II: banked human milk plus evaporated fortifier derived from modified human milk, Group III: banked human milk plus lyophilized fortifier derived from modified human milk. The newborns received the group diet when full diet was attained at 15 ± 2 days. Plasma amino acid analysis was performedon the first and last day of feeding. Comparison among groups was performed by statistical tests: one way ANOVA with Tukey's post-test using SPSS software, version 20.0 (IBM Corp, NY, USA), considering a significance level of 5%. Results: Phenylalanine levels in the first and second analysis were, respectively, in Group I: 11.9 ± 1.22 and 29.72 ± 0.73; in Group II: 11.72 ± 1.04 and 13.44 ± 0.61; and in Group III: 11.3 ± 1.18 and 15.42 ± 0.83 μmol/L. Conclusion: The observed results demonstrated that human milk with fortifiers derived from human milk acted as a good substratum for preterm infant feeding both in the evaporated or the lyophilized form, without significant increases in plasma phenylalanine levels in comparison to human milk with commercial fortifier. .


Objetivo: Avaliar o perfil plasmático do aminoácido fenilalanina em recém-nascidos pré-termo alimentados com diferentes dietas de leite humano. Métodos: Foram estudados 24 recém-nascidos pré-termo de muito baixo peso, distribuídos em três grupos com diferentes dietas: Grupo I: leite humano de banco com 5% de aditivo comercial para leite humano com proteína de origem bovina (LHB-AC); Grupo II: leite humano de banco com aditivo de leite humano modificado evaporado (LHB-E); e Grupo III: leite humano de banco com aditivo de leite humano modificado liofilizado (LHB-L). Os recém-nascidos receberam a dieta definida para o grupo quando alcançaram dieta plena por 15 ± 2 dias. A análise do aminoácido plasmático foi feita no primeiro e último dias da dieta. A comparação entre os grupos foi realizada por meio do teste ANOVA de uma via, seguido pelo pós-teste de Tukey, utilizando-se o software SPSS (IBM Corp, NY, EUA), versão 20.0, e considerando um nível de significância de 5%. Resultados: As concentrações plasmáticas do aminoácido fenilalanina na primeira e segunda análises foram, respectivamente, no Grupo I (LHB-AC) 11,9±1,22 e 29,72±0,73; no Grupo II (LHB-E) 11,72±1,04 e 13,44±0,61; e no Grupo III 11,3±1,18 e 15,42±0,83 umol/L. Conclusão: Os resultados encontrados demonstram que o leite humano com aditivos do próprio leite humano comportou-se como um bom substrato para alimentação do recém-nascido pré-termo, tanto na forma evaporada como liofilizada, sem levar a aumentos significativos na concentração plasmática de fenilalanina em comparação ao leite humano com aditivo comercial. .

ABSTRACT

OBJECTIVE: to prospectively validate a previously constructed transcutaneous bilirubin (TcB) nomogram for identifying severe hyperbilirubinemia in healthy Chinese term and late-preterm infants. METHODS: this was a multicenter study that included 9,174 healthy term and late-preterm infants in eight hospitals of China. TcB measurements were performed using a JM-103 bilirubinometer. TcB values were plotted on a previously developed TcB nomogram, to identify the predictive ability for subsequent significant hyperbilirubinemia. RESULTS: in the present study, 972 neonates (10.6%) developed significant hyperbilirubinemia. The 40th percentile of the nomogram could identify all neonates who were at risk of significant hyperbilirubinemia, but with a low positive predictive value (PPV) (18.9%). Of the 453 neonates above the 95th percentile, 275 subsequently developed significant hyperbilirubinemia, with a high PPV (60.7%), but with low sensitivity (28.3%). The 75th percentile was highly specific (81.9%) and moderately sensitive (79.8%). The area under the curve (AUC) for the TcB nomogram was 0.875. CONCLUSIONS: this study validated the previously developed TcB nomogram, which could be used to predict subsequent significant hyperbilirubinemia in healthy Chinese term and late-preterm infants. However, combining TcB nomogram and clinical risk factors could improve the predictive accuracy for severe hyperbilirubinemia, which was not assessed in the study. Further studies are necessary to confirm this combination. .


OBJETIVO: validar de forma prospectiva um nomograma de bilirrubina transcutânea (BTc) para identificar hiperbilirrubinemia grave em neonatos a termo e pré-termo tardios saudáveis na China. MÉTODOS: foi realizado um estudo multicêntrico que incluiu 9174 neonatos a termo e pré-termo tardios saudáveis em oito unidades da China. Foram realizadas dosagens de BTc utilizando um bilirrubinômetro. Os valores de BTc foram traçados em um nomograma de BTc para identificara capacidade de predição de hiperbilirrubinemia significativa. RESULTADOS: 972 recém-nascidos (10,6%) desenvolveram hiperbilirrubinemia significativa. O percentil 40 de nosso nomograma pode identificar todos os recém-nascidos com risco de hiper-bilirrubinemia significativa, porém com baixo valor preditivo positivo (VPP) (18,9%). De 453 recém-nascidos acima do percentil 95, 275 recém-nascidos desenvolveram posteriormente hiperbilirrubinemia significativa, com VPP elevado (60,7%), porém com baixa sensibilidade (28,3%). O percentil de 75 foi altamente específico (81,9%) e moderadamente sensível (79,8%). A área sob a curva (ASC) de nosso nomograma de BTc foi de 0,875. CONCLUSÕES: este estudo validou o nomograma de BTc, que pode ser utilizado para prever hiperbilirrubinemia significativa em neonatos a termo e pré-termo tardios saudáveis na China. Contudo, combinar o nomograma de BTc e fatores de risco clínicos pode melhorar a precisãode predição da hiperbilirrubinemia grave, o que não foi avaliado neste estudo. São necessários estudos adicionais para confirmar essa combinação. .

ABSTRACT

OBJECTIVES: To analyze and compare the evolution of hematological parameters and body iron content between exclusively breastfed late-preterm and term newborns during the first two months of life. METHODS: Cohort study. Weight, length, head circumference, body mass index, hemoglobin, hematocrit, reticulocytes, total iron-binding capacity, transferrin saturation, serum iron and ferritin were measured in 25 late-preterm and 21 term newborns (at birth and at one and two months of age) who were exclusively breastfed. Statistical analysis: Kolmogorov-Smirnov test, one-way ANOVA or Kruskal-Wallis test; and Student's t-test or Mann-Whitney test. Significance: p<0.05. RESULTS: The corrected gestational ages of the late-preterm infants were 39.98 weeks at one month of life and 44.53 weeks at two months. Anthropometric measures and the body mass index increased over time (p<0.001) and hemoglobin, hematocrit, reticulocytes and body iron content decreased (p<0.001). Late-preterm infants at term corrected gestational age had reduced hemoglobin, hematocrit and reticulocyte concentrations, and reduced total iron-binding capacity (p<0.001) and serum iron (p = 0.0034) compared with values observed in term newborns at birth. Late-preterm newborns at a corrected gestational age of one month post-term ...

ABSTRACT

Introducción: la eritropoyetina alfa recombinante forma parte del tratamiento de la anemia de la prematuridad. En Cuba su uso ha sido limitado y controvertido en cuanto a esquema y dosis empleada. Métodos: ensayo clínico prospectivo, multicéntrico, no aleatorizado, de eficacia y seguridad de eritropoyetina en la disminución de transfusiones en el recién nacido pretérmino de muy bajo peso. Se incluyeron 72 neonatos con edad gestacional menor de 34 semanas posmenstruales, y peso al nacer menor o igual a 1 500 g, con más de 7 días posnatales e ingesta de 50 mL/kg/día. Resultados: todos recibieron eritropoyetina 300 U/kg, subcutánea, 3 veces/semana, hasta las 40 semanas de edad gestacional y suplemento de hierro y vitaminas. La eritropoyetina fue muy segura, solo se notificó con relación posible una retinopatía de la prematuridad, ligera y recuperada. Conclusiones: se transfundieron 7 pacientes (9,7 por ciento) en el curso del estudio. El uso tardío de eritropoyetina en el pretérmino de muy bajo peso confirma su eficacia y seguridad


Introduction: recombinant alpha erythropoietin is part of the treatment for anemia of prematurity. The use of this one in Cuba has been restricted and controversial as to schedule and dose. Methods: prospective, non-randomized multicenter assay on the safety and efficacy of erythropoietin in the reduction of blood transfusion in very-low-weight preterm newborn. Seventy two neonates with gestational age under 34 post-menstruation weeks, weighing equal or less than 1 500 g, over 7 days of life after birth and fed on 50 mL/kg/day were included in the study. Results: all of them received 300 U/kg erythropoietin by subcutaneous administration three times a week up to reaching 40 weeks of gestational age and an iron and vitamin supplement. Erythropoietin is very safe; it was just possibly related to slight retinopathy of prematurity, but overcome. Conclusions: seven patients were transfused (9.7 percent ) in the course of study. The late use of erythropoietin in very-low-weight preterm child confirms its efficacy and safety

ABSTRACT

Contextualizar o tratamento transfusional da anemia no recém-nascido prematuro e suas repercussões com base na revisão da literatura, promovendo a atualização de especialistas. Método: Foi pesquisada a base de dados Medline (2000-2005), utilizando-se os descritores anemia, prematuridade e transfusão sanguínea, com busca secundária de artigos. Síntese dos dados: O objetivo das transfusões é o equilíbrio entre a oferta e a demanda tecidual de oxigênio. Porém, a detecção deste equilíbrio na prática neonatal ainda requer estudos adicionais. Existe também uma fragilidade nas indicações de transfusão para a apneia e para o ganho insuficiente de peso do prematuro. Dentre as repercussões, tem sido sugerida a associação entre transfusão sanguínea, retinopatia do prematuro e displasia broncopulmonar. Conclusões: O uso de transfusões sanguíneas para reverter o ganho insuficiente de peso e a apneia do prematuro merece ser mais explorado. Também carece de maior aprofundamento a associação entre transfusões sanguíneas e ocorrência de retinopatia do prematuro e displasia broncopulmonar. É consenso a necessidade de aplicação de protocolos clínicos restritos para este tratamento...


To discuss blood transfusions to preterm infants and its consequences by reviewing the literature and on a neonatologist point of view, promoting an up to date approach to specialists. Methods: Medline (2000-2005) was searched by applying the following key words: anemia, preterm, blood transfusion, allowing for secondary research. Data synthesis: Transfusion objective is the balance between tissue oxygen demand and supply. Clinical detection of this balance deserves additional research. Indications to treat preterm apnea and poor weight gain are slender. As blood transfusion consequences, the association between blood transfusion, retinopathy and bronchopulmonar dysplasia in the preterm has been suggested. Conclusions: Blood transfusions to treat apnea and poor weight gain are slender supported in the preterm and needs additional research. The same occurs with its association to retinopathy and bronchopulmonar dysplasia in the preterm. There is a consensus among specialists that a restrictive protocol to blood transfusion is needed...

ABSTRACT

OBJETIVO: Apresentar o primeiro caso de infecção disseminada por Trichosporon spp em um recém-nascido no Brasil, discutindo alguns aspectos de manejo e tratamento. Um novo espectro de agentes infecciosos associado a infecções graves em UTI neonatais tem surgido. Ele atinge particularmente recém-nascidos com peso de nascimento abaixo de 1.000 g. A infecção por Trichosporon asahii é rara e quase sempre fatal nesse grupo. DESCRIÇÃO: É apresentado o caso de um recém-nascido de 815 g com infecção fatal por Trichosporon spp. Na literatura pesquisada nos principais bancos de dados, apenas nove artigos foram encontrados, com descrição de 14 casos de infecção por esse fungo em recém-nascidos prematuros. CONCLUSÕES: A taxa de infecção fúngica invasiva é de cerca de 6 por cento no grupo de risco referido acima, sendo a causada por Trichosporon uma possibilidade. A taxa de mortalidade desses casos é muito alta, mas o tratamento precoce com triazólicos melhora muito o seu prognóstico.


OBJECTIVE: To report the first case of disseminated Trichosporon spp infection in a newborn infant in Brazil, discussing a few aspects concerning management and treatment. A new spectrum of pathogens associated with severe infections in neonatal ICU has arisen, afflicting mainly newborn infants weighing less than 1,000 g at birth. Infection with Trichosporon asahii is rare and often fatal in this group of patients. DESCRIPTION: A case of Trichosporon spp fatal infection in a newborn weighing 815 g at birth is reported. Literature search in the main databases returned only nine articles, reporting 14 cases of infection with this fungus in preterm newborns. CONCLUSIONS: The rate of invasive fungal infection is around 6 percent in this group of patients, Trichosporon infection being a likely occurrence. Mortality rate in these cases is extremely high, but early treatment with triazole antifungals improves prognosis significantly.

ABSTRACT

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.

ABSTRACT

Preterm infants have less iron storage compared with the term one. Due to rapid growth they need more iron during infancy. This study was designed to evaluate the effect of early iron supplementation on hematologic indices and incidence of iron deficiency anemia in preterm infants. This experimental study was done on 20-days-old preterm breast-feed infants referred to the Gorgan-North of Iran primary health care services for vaccination, without any underline disease or growth retardation during 2005. They were divided to two groups [n=15 in each] and a questionnaire was completed for each case. Iron drop [2mg/kg] was given in the interventional group. Iron deficiency anemia was assesed in all sample T-student test and chi-square were used to analyze the independent variables and comparing the hematologic indices, after entering in SPSS-13 software and testing the normal distribution with komologrof-smearnoff test. Relative risk index [RR] was used to compare the two groups. The relative risk of iron deficiency anemia in the interventional group was 0.4 folds [RR=0.4,CI%95 for RR=[0.091,1.749]]. No significant difference was seen between the two groups. The finding of this study showed that iron drop supplementation for preterm infant prevent the iron defeciency anemia, although this observation was not significant

ABSTRACT

OBJECTIVE: Investigation of magnesium (Mg) homeostasis has re-emerged as an area of interest in preterm born neonates who are at risk for brain pathology. However, data regarding the association between the biologically active ionized form of Mg and gestational age (GA) at an early stage of life in newborn infants are controversial. METHODS: We evaluated the total and ionized Mg electrolyte (TMg and IMg) as well as the calcium (TCa and ICa) and pH in the cord blood and on day 2 of life in 22 neonates born at different gestational ages (< 32, 32-34 and > or =35 week) without magnesium tocolysis and absence of serious complications during pregnancy and delivery. RESULTS: The IMg fraction that accounted for 68.1+/-5.1% of the TMg in the cord blood and 67.9+/-4.5% of the TMg on day 2 of life, was significantly higher in very preterm infants (GA< 32 week) as compared to neonates with GA > 35 week. Higher IMg levels were correlated with the lower pH that was recorded in the cord blood of the very preterm infants (correlation coefficient, r=-0.80, p< 0.0001) and ICa (r = -0.52, P< 0.01). Lower pH also was correlated with the GA (P< 0.0001). However, standard multiple regression analysis showed significant association between IMg levels and decreased pH but not the gestational age or ICa (beta=-1.10+/-0.21, p< 0.00009). CONCLUSION: Extremely preterm infants even without additional exposure to tocolytic magnesium are at risk for the lower pH associated elevation of ionized Mg, which should be considered during the management of these infants in order to prevent hypermagnesemia-related pathology.

ABSTRACT

BACKGROUND AND OBJECTIVES: Determine the extent of agreement and correlation between arterial samples and venous (obtained from a venous umbilical catheter), with respect to measurements of pH, bicarbonate, base excess and lactate, in critically ill term and premature newborns. METHODS: Arterial blood samples (0.5-1 mL) were obtained for gas analysis by radial artery puncture, and, within the limit of 5 minutes, samples were obtained from venous umbilical catheters. Bland-Altman plots were used to depict agreement between arterial and venous measurements. Limits of agreement were defined as the mean difference ± 2SD (Standard Deviation). Correlation was assessed by Pearson's method. RESULTS: A hundred and six samples (53 pairs) were taken from 53 patients for analysis of bicarbonate, pH and base excess. Lactate was analyzed in 49 pairs of samples. Differences were within the limits of agreement in 94.3 percent of pairs of samples for pH, and the same percentage was observed for bicarbonate. There was agreement in 96.2 percent of pairs for base excess, and in 91.8 percent for lactate. Mean differences were 0.03 units for pH, -1.2 mmol/L for bicarbonate, -0.24 mmol/L for base excess and 0.33 mmol/L for lactate. Pearson's correlation coefficients (r) were 0.87 for pH, 0.76 for bicarbonate, 0.86 for base excess and 0.95 for lactate. CONCLUSIONS: Although single venous values cannot be used as equivalent to arterial for assessing acid base status in newborns, venous blood samples can be used serially for monitoring trends over time.


JUSTIFICATIVA E OBJETIVOS: Determinar o grau de concordância e correlação entre amostras arteriais e as obtidas através de um cateter venoso umbilical, com relação ao pH, bicarbonato, excesso de base (BE) e lactato, em recém-nascidos prematuros e de termo, criticamente doentes. MÉTODO: Foram obtidas amostras para gasometria (0,5 - 1 mL), por punção de artéria radial, e, dentro do limite de 5 minutos, do cateter venoso umbilical. O método de Bland-Altman foi utilizado para demonstrar a concordância entre as medidas. Os limites de concordância foram definidos como a diferença média ± 2 DP. Para as correlações foi utilizado o método de Pearson. RESULTADOS: Cento e seis amostras (53 pares) de 53 pacientes foram analisadas para bicarbonato, pH e BE. Foi dosado lactato em 49 pares de amostras. Houve concordância em 94,3 por cento dos pares de amostras para o pH, e este mesmo percentual foi observado para o bicarbonato. Para o excesso de base, a concordância foi de 96,2 por cento, e de 91,8 por cento para o lactato. As diferenças médias foram 0,03 unidade para o pH, -1,2 mmol/L para o bicarbonato, -0,24 mmol/L para o excesso de base e 0,33 mmol/L para o lactato. Os coeficientes de correlação de Pearson (r) foram 0,87 para o pH, 0,76 para o bicarbonato, 0,86 para o excesso de base e 0,95 para o lactato. CONCLUSÕES: Os valores venosos isolados não podem ser usados como equivalentes aos arteriais para a avaliação do estado ácido-básico em recém-nascidos. As amostras venosas poderiam ser usadas de forma serial, para monitorizar tendências ao longo do tempo.

ABSTRACT

Plasma amino acid levels have never been studied in the placental intervillous space of preterm gestations. Our objective was to determine the possible relationship between plasma amino acids of maternal venous blood (M), of the placental intervillous space (PIVS) and of the umbilical vein (UV) of preterm newborn infants. Plasma amino acid levels were analyzed by ion-exchange chromatography in M from 14 parturients and in the PIVS and UV of their preterm newborn infants. Mean gestational age was 34 ± 2 weeks, weight = 1827 ± 510 g, and all newborns were considered adequate for gestational age. The mean Apgar score was 8 and 9 at the first and fifth minutes. Plasma amino acid values were significantly lower in M than in PIVS (166 percent), except for aminobutyric acid. On average, plasma amino acid levels were significantly higher in UV than in M (107 percent) and were closer to PIVS than to M values, except for cystine and aminobutyric acid (P < 0.05). Comparison of the mean plasma amino acid concentrations in the UV of preterm to those of term newborn infants previously studied by our group showed no significant difference, except for proline (P < 0.05), preterm > term. These data suggest that the mechanisms of active amino acid transport are centralized in the syncytiotrophoblast, with their passage to the fetus being an active bidirectional process with asymmetric efflux. PIVS could be a reserve amino acid space for the protection of the fetal compartment from inadequate maternal amino acid variations.

ABSTRACT

The effect of the trace elements on retinopathy of prematurity (ROP) were studied. Thirty preterm infants who had potential high risk factors of ROP were selected as observation group and 18 normal infants as control groups. By using atom spectrophotometer, the contents of serum trace elements (Mg, Cu, Zn, Mn, Se) were measured and analyzed statistically. The contents of serum Zn, Cu and Se in observation group were 0.75+/-0.22, 0.41+/-0.20 and (134.07+/-71.57)x10(-3) mg/L respectively, and 0.55+/-0.12, 0.65+/-0.194 and (202.92+/-44.71)x10(-3) mg/L in control group respectively (P0.05). It was concluded that the contents of serum Cu and Se in preterm infants who had high risk factors of ROP were obviously lower than in the controls. The contents of serum Cu and Se in the ROP infants were also much lower while contents of Zn much higher. Attention should be paid to the detection of the trace elements in preterm infants in order to prevent the deficiencies of Cu and Se. Only in this way can we prevent the deficiencies of Cu and Se, so as to decrease the ROP risk factors and prevent the disease.

ABSTRACT

Increased pulmonary vascular resistance in preterm newborn infants with respiratory distress syndrome is suggested, and endothelin-1 plays an important role in pulmonary vascular reactivity in newborns. We determined umbilical cord blood and neonatal (second sample) levels of endothelin-1 in 18 preterm newborns with respiratory distress syndrome who had no clinical or echocardiographic diagnosis of pulmonary hypertension and 22 without respiratory distress syndrome (gestational ages: 31.4 ± 1.6 and 29.3 ± 2.3 weeks, respectively). Umbilical cord blood and a second blood sample taken 18 to 40 h after birth were used for endothelin-1 determination by enzyme immunoassay. Median umbilical cord blood endothelin-1 levels were similar in both groups (control: 10.9 and respiratory distress syndrome: 11.4 pg/mL) and were significantly higher than in the second sample (control: 1.7 pg/mL and respiratory distress syndrome: 3.5 pg/mL, P < 0.001 for both groups). Median endothelin-1 levels in the second sample were significantly higher in children with respiratory distress syndrome than in control infants (P < 0.001). There were significant positive correlations between second sample endothelin-1 and Score for Neonatal Acute Physiology and Perinatal Extension II (r = 0.36, P = 0.02), and duration of mechanical ventilation (r = 0.64, P = 0.02). A slower decline of endothelin-1 from birth to 40 h of life was observed in newborns with respiratory distress syndrome when compared to controls. A significant correlation between neonatal endothelin-1 levels and some illness-severity signs suggests that endothelin-1 plays a role in the natural course of respiratory distress syndrome in preterm newborns.
