No. of bitstreams: 1 DISSERTA??O Julia PDF.pdf: 1629248 bytes, checksum: ea997da48258fc4f635cbdab11d472e4 (MD5) Previous issue date: 2018-03-14 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Prematurity is a global health problem that results in high morbidity and mortality, especially in infants born with less than 32 weeks of gestational age and weighing less than 1500 grams (very low birth weight ? VLBW). Currently, prematurity is the leading cause of infant mortality and it is estimated that each year 15 million premature babies are born in the world. Health problems in short and long term are widely known in these newborns, such as pulmonary, cardiovascular, metabolic, neurological, infections, as well as vision and hearing deficiencies. Emotional and financial consequences are also being observed in these families, as well as high costs to health systems. In order to elucidate the trend over the last decades of this group of newborns, this study was carried out to verify the prevalence, mortality and association with some risk factors. For this purpose, we used data from the Pelotas birth cohorts from 1982, 1993, 2004 and 2015 that cover all live births in the city in the year in question. Each birth was computed and anthropometric measures including weight were performed. After birth a perinatal questionnaire was applied to the mothers. Mortality was identified through visits to hospitals, cemeteries and registry offices, and from 2004 on, it was evaluated through the SIM (Mortality Information System). Over these years, 225 individuals were born alive weighing <1500g, which represented our object of study. In addition to this specific group we also observed the evolution of birth prevalence by birth weight groups and neonatal mortality (up to 28 days of life) also divided by weight. The reviews of number of births and mortality were descriptive. For the contingency tables (birth weight and mortality by weight), chi-square test for proportions was used and Poisson regression with robust variance was used to correlate the risk factors. The results showed that there was a significant increase in the prevalence of VLBW from the year 2004, which remained high in 2015. A significant reduction in neonatal mortality was observed over the years, both in this specific group and in general mortality. Regarding the risk factors studied, there was a significant relation found between lower family income (mainly between the poorest 60% and the richest 40%) and VLBW but no relation was found between VLBW and maternal age or type of delivery. With this study it was possible to aggregate knowledge and demonstrate the trend of this group of newborns over 33 years and to correlate some risk factors in a medium sized city that can represent the reality of a large part of Brazil. In order to promote the reduction of the prevalence, mortality and morbidity of these newborns, investments in prevention as well as in the care of these newborns should be made. Committees and prevention protocols are being created in different parts of the world. We hope to draw attention to this group of babies, contribute with our data and influence new studies on this very relevant topic. / A prematuridade ? um problema de sa?de global que resulta em alta morbimortalidade, principalmente em beb?s que nascem com menos de 32 semanas de idade gestacional e menores que 1500 gramas de peso (muito baixo peso ao nascer ? MBPN). Atualmente, a prematuridade ? a principal causa de mortalidade infantil e, a estimativa ? que, a cada ano, nas?am 15 milh?es de prematuros no mundo. Sequelas em curto e em longo prazo s?o amplamente conhecidas nesses rec?m-nascidos como doen?as pulmonares, cardiovasculares, metab?licas, neurol?gicas, infecciosas, al?m de problemas de vis?o e de audi??o. Consequ?ncias emocionais e financeiras est?o sendo observadas nas fam?lias, assim como um alto custo nos sistemas de sa?de. Para auxiliar na compreens?o desta tend?ncia ao longo das ?ltimas d?cadas deste grupo de rec?m-nascidos foi realizado este estudo, que visou verificar a preval?ncia, a mortalidade e a associa??o com alguns fatores de risco. Para isto, foram utilizados dados das coortes de nascimentos de Pelotas dos anos de 1982, 1993, 2004 e 2015 que contemplam todos os nascidos vivos na cidade no ano em quest?o. Cada nascimento foi computado e medidas antropom?tricas incluindo o peso foram realizadas. Ap?s o nascimento foi aplicado ?s m?es um question?rio perinatal. A mortalidade foi identificada por meio de visitas a hospitais, cemit?rios, tabelionatos e cart?rios, sendo, a partir de 2004, avaliada por meio do SIM (Sistema de Informa??o de Mortalidade). Ao longo desses anos, nasceram vivos 225 indiv?duos pesando <1500g, que representaram o nosso objeto de estudo. Al?m de estudar este grupo espec?fico tamb?m observamos a evolu??o da preval?ncia de nascimentos por grupos de peso ao nascer e a mortalidade neonatal (at? 28 dias de vida) dividida por peso. As an?lises de n?mero de nascimentos e de mortalidade foram descritivas. Para as tabelas de conting?ncia (peso ao nascer e mortalidade por peso) foi utilizado o teste de qui-quadrado para propor??es e para correlacionar os fatores de risco foi empregada a regress?o de Poisson com vari?ncia robusta. Os resultados demostraram que houve um aumento significativo da preval?ncia de MBPN a partir do ano de 2004, a qual se manteve alta em 2015. Foi observada uma redu??o importante na mortalidade neonatal ao longo dos anos, tanto desse grupo espec?fico quanto da mortalidade em geral. Sobre os fatores de risco estudados, houve rela??o significativa entre menor renda familiar (principalmente entre os 60% mais pobres e os 40% mais ricos) e MBPN, mas n?o foi encontrada rela??o entre MBPN e idade materna ou tipo de parto. Com este estudo foi poss?vel agregar conhecimento e demonstrar a tend?ncia deste grupo de rec?m-nascidos ao longo de 33 anos e correlacionar alguns fatores de risco, em uma cidade de porte m?dio que pode representar grande parte da realidade brasileira. Para promover a diminui??o da preval?ncia, mortalidade e morbidade dos rec?m-nascidos de MBPN, ? imprescind?vel que haja investimentos na preven??o, assim como na assist?ncia a estes rec?m-nascidos. Comit?s e protocolos de preven??o est?o sendo criados em diferentes partes do mundo. Esperamos chamar aten??o para este grupo de beb?s, contribuir com os nossos dados e influenciar novos estudos sobre este tema t?o relevante.

Introdução Os recém-nascidos de muito baixo peso (<1.500g) necessitam de aporte adequado de nutrientes para desenvolver-se satisfatoriamente. O leite humano é fundamental na sua alimentação, já que possui uma composição nutricional balanceada que inclui nutrientes essenciais, tais como os ácidos graxos poli-insaturados, incluindo os ácidos ômega 3 e 6, de extrema importância para o desenvolvimento do sistema nervoso central e retina. No entanto, apenas o leite materno pode não ser suficiente para suprir essas necessidades, necessitando, portanto, de suplementação. Atualmente, surgiu a possibilidade de adequação do leite humano acrescido de um concentrado com liofilizado do próprio leite humano, que foi desenvolvido neste trabalho. Objetivos determinar a quantidade de lipídios totais e o perfil lipídico do Leite Humano Baseline (LHB) e dos Concentrados com o liofilizado de Leite Humano em diferentes momentos (Leite Humano concentrado no período imediato - LHCI, Leite Humano concentrado no período de 3 meses - LHC3m e Leite Humano concentrado no período de 6 meses - LHC6m). Métodos Foram obtidas 50 amostras de leite humano de mulheres doadoras do Banco de Leite Humano da FMRP-USP que aceitaram participar do estudo. A quantificação de lipídeos ocorreu pelo Analisador de Leite Humano MIRIS® e o perfil de ácidos graxos foi determinado por CG-FID, SHIMADZU®. Resultados Houve uma concentração de lipídios totais no LHCI em relação ao LHB; a concentração (% em relação ao total de ácidos graxos) dos ácidos foi de: palmítico (C16:0) 22,30% LHB, 21,46% LHCI, 21,54% LHC3m e 21,95% LHC6m (p<0,01); oleico (C18:1n-9) 30,41% LHB, 30,47% LHCI, 30,55% LHC3m e 29,79% LHC6m (p=0,46); linoléico (C18:2 n-6) 19,62% LHB, 19,88% LHCI, 19,49% LHC3m e 19,45% LHC6m (p=0,58); araquidônico (C20:4 n-6) 0,35% LHB, 0,16% LHCI, 0,13% LHC3m e 0,15% LHC6m (p<0,01); ?- linolênico (C18:3 n-3) 1,32% LHB, 1,37% LHCI, 1,34% LHC3m e 1,34% LHC6m (p=0,14); docosahexaenóico (C22:6 n- 3) 0,10% LHB, 0,06% LHCI, 0,05% LHC3m e 0,06% LHC6m (p<0,01). Há modificações específicas em alguns ácidos graxos, no entanto a somatória de ácidos graxos por suas classes estruturais não apresentam diferenças. Conclusão Apesar das pequenas diferenças encontradas no perfil lipídico, o concentrado com leite humano liofilizado é um alimento que pode vir a atender as necessidades do recém-nascido, já que houve aumento dos lipídios totaise preservação dos nutrientes essenciais presentes apenas no leite materno, mas estudos clínicos ainda precisam ser feitos para avaliar a segurança e eficácia do concentrado como alimentação dos recém-nascidos de muito baixo peso. / Introduction Very low birth weight infants (<1,500 g) require adequate nutrient intake to develop satisfactorily. Human milk is essential in its diet, since it has a balanced nutritional composition that includes essential nutrients, such as polyunsaturated fatty acids, including omega 3 and 6 acids, of extreme importance for the development of the central nervous system and retina. However, only breast milk may not be sufficient to meet these needs, thus requiring supplementation. Nowadays, the possibility of adapting the human milk plus a concentrate with lyophilized from the human milk itself, which was developed in this work, has arisen. Objectives To determine the amount of total lipids and the lipid profile of Human Baseline Milk (LHB) and Concentrates with human milk lyophilized at different times (Human Milk Concentrated in the immediate period - LHCI, Concentrated Human Milk in the 3-month period - LHC3m and Human Milk Concentrated in the 6-month period - LHC6m). Methods Fifty samples of human milk from women donors of the Human Milk Bank of FMRP-USP who were accepted to participate in the study were obtained. Lipid quantification was performed by the MIRIS® Human Milk Analyzer and the fatty acid profile was determined by CG-FID, SHIMADZU®. Results There was a total lipid concentration in LHCI relative to LHB; the concentration (% of total fatty acids) of the acids was: palmitic (C16: 0) 22.30% LHB, 21.46% LHCI, 21.54% LHC3m and 21.95% LHC6m (p <0) , 01); oleic acid (C18: 1n-9) 30.41% LHB, 30.47% LHCl, 30.55% LHC3m and 29.79% LHC6m (p = 0.46); linoleic acid (C18: 2 n-6) 19.62% LHB, 19.88% LHCI, 19.49% LHC3m and 19.45% LHC6m (p = 0.58); arachidonic (C20: 4 n-6) 0.35% LHB, 0.16% LHCl, 0.13% LHC3m and 0.15% LHC6m (p <0.01); ?-linolenic acid (C18: 3 n-3) 1.32% LHB, 1.37% LHCI, 1.34% LHC3m and 1.34% LHC6m (p = 0.14); (C22: 6 n-3) 0.10% LHB, 0.06% LHCl, 0.05% LHC3m and 0.06% LHC6m (p <0.01). There are specific modifications in some fatty acids, however the sum of fatty acids by their structural classes do not present differences. Conclusion Despite the small differences found in the lipid profile, the concentrate with freeze-dried human milk is a food that can meet the needs of the newborn, since there was an increase in total lipids and preservation of essential nutrients present only in breast milk, butclinical studies still need to be done to evaluate the safety and efficacy of concentrate as a feed for very low birth weight infants.

O Câncer colorretal (CCR) é um problema de saúde importante devido a sua incidência e mortalidade elevadas. O rastreamento e o diagnóstico precoce são a principal estratégia para diminuir a mortalidade pelo CCR. A colonoscopia convencional (CC), constitui o melhor método para o diagnóstico precoce do CCR e para o diagnóstico e tratamento das lesões precurssoras. Entretanto a CC apresenta taxas de falha de detecção não desprezíveis. A colonoscopia com magnificação de imagem (CM), vem sendo utilizada com o intuito de melhorar a performance da CC. A sua principal vantagem é a possibilidade de diferenciar lesões neoplásicas de não-neoplásicas, de maneira que apenas lesões neoplásicas seriam retiradas, diminuindo custos e riscos relacionados ao rastreamento por colonoscopia. O objetivo deste estudo é determinar a acurácia da CM para o diagnóstico diferencial entre lesões neoplásicas e não-neoplásicas do intestino grosso por meio da comparação entre o diagnóstico endoscópico e o fornecido pelo exame histopatológico convencional. Entre abril de 2002 e outubro de 2003, cento e vinte pacientes foram incluídos no estudo, tendo-se encontrado 200 lesões. Todas as lesões foram classificadas endoscopicamente através da CM com alta magnificação (até 200X), associada a cromoscopia com índigo carmim, de acordo com a classificação proposta por Kudo, e em seguida excisadas ou biopsiadas para estudo histopatológico. A acurácia da determinação do diagnóstico diferencial endoscópico em relação à histopatologia entre lesões neoplásicas e não-neoplásicas foi de 78,5%. A diferença da CM em relação ao exame histopatológico foi estatisticamente significativa (p<0,0001). Conclui-se que, no atual estágio de desenvolvimento, a CM, pela sua acurácia, não permite excluir o exame histopatológico para o diagnóstico diferencial entre as lesões neoplásicas e não-neoplásicas do intestino grosso. / Bacterial meningitis in the neonatal period is a severe disease, associated to elevated mortality and sequelae in around 12 to 29% of the survivors. Newborns whose birth weight is < 2,500g have a 3-fold increase in the risk of acquiring meningitis when compared to those whose weight is > or = 2,500; among those with very low birth weight (< 1,500g), the risk increases 17-fold. Objectives: General: to describe the clinical picture and the complications of bacterial meningitis in two groups of newborns, considered according to birth weight (< 2,500g or > or = 2,500g). Specific: to describe and compare the etiological agents, the frequency of neurological signs and symptoms and complications, mortality rate and duration of treatment in both groups. Methods: Observational study of 87 newborns with bacterial meningitis, admitted at the Neonatal Intensive Care Unit (NICU) of Instituto da Criança of Hospital das Clínicas of the University of São Paulo School of Medicine, during an 11-year period (January 1994 to December 2004). The data were obtained through the analysis of hospital files. Statistical analysis was carried out with Fisher\'s exact test and the non-parametric Mann Whitney test. Results: Bacteria were identified in the cerebrospinal fluid (CSF) of 39% of the patients, with 50% of them being Gram-positive and 50%, Gram-negative. Most neonates presented unspecific signs and symptoms: fever (63.2%), irritability (31%), and lethargy (26.4%). The neurological findings occurred in 35.3% of the cases. Complications occurred in 48.2% of the neonates, and were mainly seizures (23%), intracranial hemorrhage (14.9%) and hydrocephalus (13.8%) with a mortality rate of 11.5%. At the comparison between clinical evolution and birth weight, associations between weight > or = 2,500g and seizures (p=0.047), weight > or = 2,500g and concave fontanel (p=0.019), bacteria in the CSF and complications (p=0.008) and bacteria in the CSF and death (p=0.043) were observed. Conclusions: The etiological agents most often identified in the CSF were enterobacteria (41%), followed by B Streptococcus (17.5%), non-B Streptococcus (17.5%), Staphylococcus aureus (11.7%), Neisseria meningitidis (8.8%) and Enterococcus faecalis (3.0%), with no statistical difference between the type of bacteria and birth weight. The predominant signs and symptoms were unspecific, with neurological findings in 35% of the cases. The higher frequency of neurological signs and symptoms in newborns with birth weight > or = 2,500g suggest a higher degree of central nervous system maturity in these infants. Although the mortality was lower than that observed in previous studies at the same Service, the frequency of complications was high, regardless of birth weight. The presence of bacteria in the CSF was associated to a higher frequency of seizures and mortality. The need for prolonged treatment in newborns with low birth weight suggests higher disease severity in this group of neonates.

A nutrição do recém-nascido pré-termo de muito baixo peso representa um desafio para a equipe multiprofissional devido a condições especiais, como o metabolismo acelerado, diminuição das reservas orgânicas, maior risco de complicações associadas à imaturidade do sistema digestivo e a capacidade reduzida de adaptação frente a situações de sobrecarga hidro-eletrolítica. A preocupação com a nutrição do pré-termo justifica-se pela necessidade de promover velocidade de crescimento físico e desenvolvimento semelhantes à da vida intra-uterina. Objetivos: a) Geral; comparar o ganho ponderoestatural e a freqüência de complicações clínicas em recém-nascidos prétermo com peso inferior a 1500g, alimentados exclusivamente com leite humano cru da própria mãe, com e sem a suplementação de aditivo, até atingirem o peso de 1800g; b)Específicos: descrever e comparar o ganho pondero-estatural e a freqüência de complicações clínicas em recém-nascidos pré-termo com peso inferior a 1500g, alimentados exclusivamente com leite humano cru da própria mãe, com e sem a suplementação de aditivo, até atingirem o peso de 1800g. Métodos: Ensaio clínico prospectivo randomizado duplo-cego em 40 recém-nascidos pré-termo com peso de nascimento inferior a 1500g internados em unidade de terapia intensiva neonatal no período de agosto de 2005 a abril de 2007. Para detectar a diferença de 3,0g/Kg/dia no ganho de peso, com desvio padrão de 4,0g/Kg/dia com nível de significância de 5% e poder de teste de 80%, foi calculada uma amostra com 20 neonatos em cada grupo (controle e intervenção). Na análise estatística foram utilizados o teste exato de Fisher, t de Student, Kolmogorov-Smirnov e teste não paramétrico de Mann Whitney. Resultados: O ganho ponderal nos recém-nascidos pré-termo de muito baixo peso que receberam leite humano cru da própria mãe com aditivo foi de 24,4g/dia e de 21,2g/dia no grupo que recebeu leite humano (p=0,075). Com relação ao comprimento, houve aumento de 1,09 cm/semana no grupo que recebeu leite humano cru da própria mãe com aditivo e 0,87cm/semana no grupo que recebeu leite humano puro (p=0,003). Quanto às complicações clínicas, não houve diferença significante com relação à intolerância digestiva, distensão abdominal, hipernatremia e episódios de infecção. Conclusões: A suplementação de aditivo no leite humano cru da própria mãe, na concentração de 5%, após a oferta hídrica da dieta atingir 100ml/Kg/dia e até o recém-nascido apresentar peso de 1800g, proporcionou ganho ponderal médio diário superior ao obtido no grupo controle, embora sem diferença significante. Houve aumento significativo do comprimento em relação ao grupo controle. Não foram observadas complicações clínicas relacionadas ao uso de aditivo no leite humano cru da própria mãe do recém-nascido pré-termo. / The nutrition of very low birth weight preterm newborns represents a challenge for a multiprofessional team due to special conditions, such as accelerated metabolism, reduction of organic reserves, higher risk of complications associated to the immature digestive system, and reduced capacity of adaptation in face of hydroelectrolytic overload situations. The concern with the preterm infant nutrition is justified by the need of promoting physical growth velocity and development similar to those in the intrauterine life. Objectives: a) General: to compare the ponderal-stature gain and the frequency of clinical complications in preterm newborns weighting less than 1500g, exclusively fed with their own mothers raw human milk with or without additive until reaching 1800g; b) Specific: to describe and compare the ponderal-stature gain and the frequency of clinical complications in preterm newborns weighting less than 1500g, exclusively fed with their own mothers raw human milk with or without additive until reaching 1800g. Methods: Prospective double-blind randomized controlled trial in 40 preterm newborns with birth weight lower than 1500g hospitalized in neonatal intensive care unit from August 2005 to April 2007. In order to detect the difference of 3.0g/Kg/day in the gain of weight, with standard deviation of 4.0g/Kg/day, significance level of 5% and power of test of 80%, a sample with 20 newborns in each group (control and intervention) was calculated. In the statistical analysis, Fisher exact test, t of Student, Kolmogorov-Smirnov test and Mann Whitney non-parametric test were utilized. Results: The ponderal gain in very low birth weight preterm newborns who have received raw human milk of their own mothers with additive was 24.4g/day and 21.2g/day in the group receiving human milk (p=0.075). In regard to the stature, there was an increase of 1.09 cm/week in the group receiving human milk of their own mothers with additive and 0.87cm/week in the group receiving pure human milk (p=0.003). As for clinical complications, there was no significant difference in regard to digestive intolerance, abdominal distension, hypernatremia and episodes of infection. Conclusions: The supplementation of additive in the own mother human milk, in the concentration of 5%, after the diet hydric offer supply reaches 100 ml/Kg/day and until the newborn weights 1800g, has allowed a daily average ponderal gain higher than that obtained in the control group, although with no significant difference. There was a significant increase of stature in regard to the control group. No clinical complications regarding the use of additive in the raw human milk of preterm newborns own mothers were observed.

Em virtude da importância dos recém-nascidos de muito baixo peso (RNMBP) na constituição da morbidade e mortalidade infantil realizou-se estudo para identificar os fatores de risco associados ao seu nascimento e avaliar os cuidados recebidos durante a internação e os índices de mortalidade. Método. Estudo de caso-controle, abrangendo 200 recém-nascidos(RN) com peso entre 500 e 1499g(casos) e 400 RN com peso entre 3000 e 3999g (controles), no período de março de 1998 a dezembro de 2004. Foram estudadas variáveis maternas sócio-econômicas e educacionais e variáveis da gestação e do parto. Foi utilizada a análise univariada e multivariada, adotando-se um nível de significância de 5 por cento . Resultados. A percentagem de mortalidade dos RNMBP foi de 32,5 por cento , sendo o limite de viabilidade de 600g de peso e 26 semanas de idade gestacional. As principais causas básicas de óbito foram a hipertensão materna (35,3 por cento ), as infecções maternas(18,5 por cento ) e a prematuridade (18,5 por cento ) e a principal causa imediata de óbito foi a infecção(52,3 por cento ). As variáveis que estiveram relacionadas com o nascimento de RNMBP foram a idade materna igual ou acima de 35 anos, a ausência de pré-natal, as doenças na gestação, a hipertensão materna, a internação durante a gestação e a história de um filho anterior de baixo peso ao nascer. Conclusão. Muitos nascimentos de RNMBP ocorreram por causas evitáveis relacionadas com a freqüência e qualidade do pré-natal / Objective. Due to the importance of very low birth weight (VLBW) in the make up of infant morbidity and mortality, a study was performed to identify risk factors associated with their birth, and to evaluate care received while in hospital and mortality rates. Method. A case-control study, covering 200 newborns (NB) weighing between 500 and 1499g (cases) and 400 NB weighing between 3000 to 3999g (controls) during the period from March 1998 to December 2004. Maternal socioeconomic and educational variables were studied besides variables on pregnancy and delivery. Simple and multiple analysis was used, adopting a 5 per cent level of significance. Results. The mortality percentage of VLBW was 32.5 per cent , and the limit of viability was a weight of 600g and 26 weeks of gestational age. The main basic causes of death were maternal hypertension (35.3 per cent ), maternal infections (18.5 per cent ) and prematurity (18.5 per cent ), and the main immediate cause of death was infection (52.3 per cent ). The variables that were related to the birth of VLBW were maternal age equal to or above 35 years, lack of prenatal examination, diseases in pregnancy, maternal hypertension, hospitalization during pregnancy, and the history of a previous low birth weight child. Conclusion. Many VLBW births occurred due to unavoidable reasons related to the frequency and quality of pre-natal care

Introdução: O presente estudo trata da evolução da mortalidade perinatal hospitalar do município de Fortaleza-Ceará em dois momentos: 1995 e 2005. O interesse para a realização desta pesquisa parte da relevância dos cuidados oferecidos à mulher grávida e ao recém nascidocomo importante indicador da saúde materno infantil.Objetivos: Avaliar a evolução dos indicadores de saúde perinatal referentes aos nascimentos hospitalares de Fortaleza, Ceará, ocorridos em 1995 e em 2005.Metodologia: Estudo epidemiológico, do tipo ecológico, que estuda a evolução da saúde perinatal em Fortaleza, de 1995 a 2005, a partir da análise dos dados de dois estudos de base hospitalar. Todos os nascimentos foram acompanhados desde o parto até a alta ou óbito em hospital.Fizeram parte da população, todos os nascimentos e respectivos óbitos perinatais ocorridos em hospitais/maternidades públicas e particulares, conveniados com o SUS, no município de Fortaleza, CE, em 1995 e em 2005, disponíveis em dois bancos de dados já existentes.Resultados: Os resultados evidenciaram que nos dez anos (1995-2005) houve melhoria nos indicadores de saúde perinatal em Fortaleza. Os coeficientes de mortalidade perinatal hospitalar, fetal e neonatal precoce tiveram redução de 29 por cento, 19,0 por cento e de 42 por cento respectivamente. Em crianças com baixo peso ao nascer,observou-se declínio na mortalidade perinatal, fetal e neonatal precoce em todas as categorias. Chama-se atenção para a redução do coeficiente de mortalidade perinatal no grupo de recém nascidos de muito baixo peso (< 1500g), que passou de 821,1/1000 NV em 1995 para 532,2/1000 NV em 2005, com um declínio de 35,2 por cento. Quanto ao coeficiente de mortalidade neonatal precoce, a redução foi de 53,8 por cento, passando de 703,0/1000 NV para 324,7/1000 NV. Foi possível evidenciar mudanças referentes à reorganização da atenção perinatal em Fortaleza, quando se detectou uma maior participação dos hospitais públicos, que realizou um maior número de partos nos dez anos em 121 por cento por cento. Em 1995 a proporção de partos foi de 32,4 por cento e em 2005 de 71,7 por cento. Quanto à idade materna, os coeficientes de mortalidade perinatal, fetal e neonatal precoce nos dez anos tiveram reduções, com ênfase entre os filhos de mães adolescentes (10 a 19 anos). Para este grupo, o coeficiente de mortalidade perinatal obteve declínio de 54,2 por cento o de mortalidade fetal de 16,2 por cento e o de mortalidade neonatal precoce de 36,8 por cento. Conclusões: A mudança nos indicadores da saúde perinatal no município de Fortaleza mostra que houve uma melhora da atenção ao longo dos dez anos, revelando um cenário favorável na atenção prestada à mulher grávida e ao recém nascido na capital. Contudo, sabe-se que aspectos relacionados com o processo de trabalho e a organização da rede, ainda permanecem em níveis inferiores em relação , quando compara-se com outras capitais brasileiras, sendo necessárias medidas governamentais para que estas lacunas sejam remediadas / Introduction: This study deals with the evolution of perinatal mortality hospital in Fortaleza, Ceara on two occasions: 1995 and 2005. The interest for this research part of the relevance of care offered to pregnant women and newborn care as an important indicator of maternal and infant health.Objectives: To evaluate perinatal health indicators relating to hospital births in Fortaleza, occurring in 1995 and 2005.Methodology: Epidemiological study of ecological type, which studies the evolution of perinatal health in Fortaleza, from 1995 to 2005, based on the analysis of data from two hospital-based studies. All births were followed from birth until discharge or death in hospital. The population was composed of all births and perinatal deaths occurred in their hospitals / public hospitals and private contracts with the SUS in the city of Fortaleza, in1995 and 2005, available in two databases that already exist.Results: The results showed that within ten years (1995-2005) found a reduction in perinatal health indicators in Fortaleza. The hospital perinatal mortality rates, fetal and early neonatal fell by 29 per cent, 19.0 per cent and 42 per cent respectively. As birth weight were obtained decline in perinatal mortality, fetal and early neonatal in all categories. Attention is drawn to the reduction of perinatal mortality rate in the group of infants with very low birthweight (<1500g), now 821.1 / NV in 1000 to 532.2 in 1995 / 1000 NV in 2005, with a declining 35.2 per cent. As for early neonatal mortality rate, the reduction was 53.8 per cent, from 703.0 / 324.7 for 1000 NV / NV 1000. The results showed changes related to the reorganization of perinatal care in Fortaleza, when it detected a greater involvement of public hospitals, which increased the number of births in the ten years 121 per cent per cent. In 1995 the proportion of births was 32.4 per cent and 71.7 per cent in 2005. As for maternal age, perinatal mortality rates, fetal and early neonatal ten years have had reductions, with emphasis among the children of teenage mothers (10-19 years). For this group, the perinatal mortality rate decline of 84.7 per cent was obtained, the fetal mortality of 46.8 per cent and early neonatal mortality rate of 88.7 per cent.Conclusions: The change in perinatal health indicators in Fortaleza shows that there was an improvement of attention over the ten years, revealing a favorable outlook on care provided to pregnant women and newborn in capital.Contudo, it is known that aspects related to the work process and organization of the network, are still inconsistent when it is compared with other Brazilian cities, requiring government measures to these deficiencies are remedied

Die vorliegende Arbeit beschäftigt sich mit der Fragestellung, ob die Frühgeburtlichkeit eine Auswirkung auf den Spracherwerb im ersten Lebensjahr hat. Insbesondere wurde der Frage nachgegangen, ob sich die Verarbeitung der rhythmisch-prosodischen Eigenschaften von Sprache im ersten Lebensjahr und deren weitere Ausnutzung für die Entwicklung des Lexikons bei sehr untergewichtigen Deutsch lernenden Frühgeborenen im Vergleich zu Reifgeborenen unterscheidet. Die besondere Spracherwerbssituation Frühgeborener liefert weitere Erkenntnisse bezüglich der Frage, inwieweit der frühe Spracherwerb durch prädeterminierte reifungsbedingte Mechanismen und Abläufe bestimmt wird und inwieweit dessen Verlauf und die relevanten Erwerbsmechanismen durch individuelle erfahrungsabhängige Faktoren beeinflusst werden. Damit liefern die Ergebnisse auch einen weiteren Beitrag zur Nature-Nurture-Diskussion. / This research addresses the question if and how premature birth effects language acquisition during the first year of life. In particular the study focus on whether prosodic processing of language and the utilization of this knowledge for the acquisition of the lexicon during the fist year of life differs between German learning very low birth weight infants and term born infants. The specific exposure and postnatal situation of premature infants provide insights on the determination of early language acquisition and processes, and on the determination of language acquisition and its relevant mechanisms by individual experience. The results contribute to the nature-nurture discussion.

Hintergrund Ein rascher enteraler Nahrungsaufbau bei Frühgeborenen verkürzt die Zeit der parenteralen Ernährung. Somit lassen sich bestimmte Risikofaktoren beeinflussen, die evt. die Morbiditätshäufigkeit der Kinder senken könnten. Mehrere Kohortenstudien zeigten, dass ein standardisierter Nahrungsaufbau mit einer geringeren Komplikationsrate und einem schnelleren Nahrungsaufbau assoziiert ist. Ziel der Studie ist zu überprüfen, ob ein standardisiertes Ernährungsprogramm einen rascheren und komplikationsärmeren enteralen Nahrungsaufbau bei Frühgeborenen ermöglicht. Patienten und Methode In die vorliegende randomisierte, kontrollierte Studie wurden 99 Frühgeborene mit einem Geburtsgewicht von ≤1750 g aufgenommen. In der Gruppe mit standardisierter Ernährung (ST) wurde der enterale Nahrungsaufbau mit Muttermilch oder gespendeter Frauenmilch nach einem speziell ausgearbeiteten Protokoll durchgeführt. In der Gruppe mit der individuellen Ernährungsform (IN) wurde je nach Bedarf und Zustand des Kindes auch semi-elementare Nahrung (Pregomin®) gefüttert. Über die Steigerungsdynamik und Nahrungspausen wurde hier individuell entschieden. Primäres Zielkriterium war die Dauer bis zum Erreichen der vollenteralen Ernährung. Ergebnisse In der ST-Gruppe war die vollständig enterale Ernährung nach 14,93 ± 9,95 (Median 12) Tagen, in der IN-Gruppe nach 16,23 ± 10,86 (Median 14) Tagen möglich. Es konnte kein signifikanter Unterschied gefunden werden. Nur bei hypotrophen Frühgeborenen erwiesen sich die Unterschiede bei der ST-Gruppe gegenüber der IN-Gruppe als statistisch signifikant: 10,20 ± 4,78 (Median 8,5) vs. 16,73 ± 8,57 (Median 15) Tage (p = 0,045). Die Gewichtsentwicklung verlief in beiden Studiengruppen nicht different. Die Kinder in der ST-Gruppe konnten bei einem Gewicht von 116% des Geburtsgewichtes vollständig enteral ernährt werden, in der IN-Gruppe bei einem Gewicht von 122% des Geburtsgewichtes. Die Inzidenz der nekrotisierenden Enterokolitis (4%) und anderer Komplikationen blieb in beiden Studiengruppen niedrig. Die Diagnose „Ernährungsschwierigkeiten“ wurde mit klaren Symptomen definiert und in der IN-Gruppe doppelt so oft gestellt, wie in der ST-Gruppe (14 vs. 7) Schlussfolgerung Das Standardisieren führte unter den Studienbedingungen nicht zu einer Beschleunigung des Nahrungsaufbaus. Anhand unserer Ergebnisse ist es möglich, dass die hypotrophen Frühgeborenen von der standardisierten Ernährung entsprechend des Ernährungsprotokolls profitieren. Diese Hypothese muss in einer neuen Studie überprüft werden. Diese Kinder konnten schneller vollständig enteral ernährt werden, als Frühgeborene, mit individuellem enteralem Nahrungsaufbau. Ein standardisiertes Nahrungsprotokoll ist im klinischen Alltag durchsetzbar, und darauf aufbauend ein enteraler Nahrungsaufbau unter strenger klinischer Beobachtung ohne Komplikationen erfolgreich durchführbar.

Background: Children born very preterm are at an elevated risk of behavioural adjustment problems, particularly Attention-Deficit/Hyperactivity Disorder (ADHD) or inattention/hyperactivity difficulties. Importantly, these risks remain even after controlling for the effects of social risk factors correlated with very preterm birth. Behavioural outcomes in follow-up studies of children born very preterm are typically assessed using parent reports only. However, the extent to which behavioural problems are evident across multiple contexts (i.e., parent or teacher report) is not well known. Furthermore, the neonatal neuropathology underlying these behavioural difficulties in this population remains poorly understood. Aims: Three research studies are undertaken primarily to examine: (1) the degree of agreement between parent and teacher reports of child behaviour adjustment, and the extent of situational (parent- or teacher-identified) and pervasive (parent- and teacher-identified) inattention/hyperactivity problems at ages 4, 6, and 9 years among children born very preterm and full-term; (2) to cross-validate the classification of children with situational and pervasive inattention/hyperactivity problems across the ages of 4 to 9, for a clinical diagnosis of ADHD at age 9 years; (3) to document risk of persistent ADHD symptoms between ages 4 and 9 years in children born very preterm, and to examine associations between qualitative measures of neonatal cerebral white matter injury/abnormality and quantitative volumetric measures of cerebral structural development, identified using magnetic resonance imaging (MRI) at term equivalent age, and children’s later risks of persistent symptoms. Persistent ADHD symptoms were defined as behavioural inattention/hyperactivity problems shown at ages 4, 6, and 9, along with meeting the criteria for an ADHD clinical diagnosis at age 9 years. Methods: As part of a prospective longitudinal study, a regional cohort of 110 very preterm (≤ 33 weeks of gestation) and 113 full-term children born between 1998 and 2000 were studied from birth to age 9 years. At term equivalent age, all children born very preterm and 10 children born full-term underwent an MRI scan that was analysed using qualitative measures for cerebral white matter injury/abnormality, and quantitative volumetric techniques with tissue segmentation and regional parcellation for cortical and subcortical grey matter, myelinated and unmyelinated white matter, and cerebrospinal fluid. At ages 4, 6 (corrected for the extent of prematurity), and 9 years (uncorrected), children were screened for behavioural adjustment problems including inattention/hyperactivity symptoms using the parent and teacher rated Strengths and Difficulties Questionnaire (SDQ). At age 9, the Development and Well-Being Assessment (DAWBA) structured psychiatric interview was also completed with primary caregiver and an independent clinical diagnosis of ADHD determined by a child psychiatrist blinded to child’s perinatal history and group status. Results: Agreement between parent and teacher reports regarding child behaviour adjustment was lower for children born very preterm than full-term (mean alternative chance-correlated coefficient, AC₁ = 0.63 vs. 0.80). Across all assessment time-points, very preterm birth was associated with on average a 2-fold increased risk of behavioural inattention/hyperactivity problems. These elevated risks largely reflected high rates of situational symptoms (very preterm = 22.3% − 31.7%; full-term = 10.9% − 16.7%). In contrast, rates of pervasive symptoms were relatively modest (very preterm = 6.8% − 11.5%; full-term = 4.7% − 7.3%). Examination of the predictive validity of inattention/hyperactivity problems identified using parent and teacher reports showed that children exhibiting situational symptoms at ages 4 and 6 were much less likely than those exhibiting pervasive symptoms, for a subsequent clinical diagnosis of ADHD at age 9 years (very preterm = 29% − 47.8% vs. 66.7% − 75%; full-term = 13.3% − 22.2% vs. 33.3% − 40%). Furthermore, receiver operating characteristic curves fitted to the data showed that children born very preterm exhibiting inattention/hyperactivity problems at two or three time-points (area under curve, AUC = .909) have better predictive validity for later ADHD diagnosis, compared to those exhibiting symptoms at age 4 (AUC = .794) or 6 years (AUC = .813) only. Children born very preterm were also at an elevated risk of persistent ADHD symptoms across the ages of 4 to 9 years, with the risk being 5-fold higher than their full-term peers (13.1% vs. 2.8%). Results also revealed possible associations between neonatal neuropathology and later risk of persistent ADHD symptoms. There were no significant linear associations between increasing severity of qualitative neonatal MRI measures of white matter injury/abnormality and very preterm children’s later risk of persistent ADHD symptoms. However, reduction in total cerebral tissue volumes and corresponding increase of cerebrospinal fluid (adjusted for intracranial volume) were significantly associated with increased risk of persistent symptoms in children born very preterm (p = .001). In terms of regional tissue volumes, total cerebral tissues in the dorsal prefrontal region showed the largest volumetric reductions among all the subregions in children born very preterm exhibiting persistent ADHD symptoms, with 3.2 ml (7%) and 8.2 ml (16%) lower tissue volumes than children born very preterm and full-term without persistent symptoms, respectively. Conclusions: Reliance on a single informant to examine child behaviour outcomes at a single time-point may lead to an under- or over-estimation of later ADHD risks. Combining reports from multiple informants and repeated assessments over time may provide better clinical prognostic validity. Children born very preterm are at an increased risk of behavioural inattention/hyperactivity problems during their early school years; although risks of more severe, pervasive problems are relatively modest compared with situational problems. Behavioural adjustment difficulties recognised as early as during preschool age using standardised behaviour screening tools can be a reliable indicator for identifying children born very preterm at risk of subsequent ADHD diagnosis. Finally, study findings suggest that increased risk of ADHD symptoms in children born very preterm can at least in part be accounted for by disturbances to neonatal cerebral growth and maturation.

Orientador: Elenice Deffune / Resumo: Introdução: As transfusões de concentrados de hemácias (CHs) são frequentes em recém-nascidos (RNs) apesar do aumento do tempo para clampeamento de cordão umbilical ao nascer, da redução no volume de sangue coletado para exames laboratoriais e da adesão aos protocolos restritivos de sua indicação. Diversas correlações já foram descritas entre transfusões e piores desfechos perinatais. Casuística e métodos: Estudo analítico, observacional, transversal do tipo coorte realizado na Unidade de Terapia Intensiva Neonatal (UTIN) do Hospital das Clínicas da Faculdade de Medicina de Botucatu, com análise de prontuários de 170 recém-nascidos menores de 1500g ao nascimento admitidos durante os anos de 2015 e 2016, divididos em grupos transfundido (Tf) e não transfundido (NTf). Calculadas diferença de proporções e frequências simples e relativa; para comparação entre os grupos foi usado o teste t-student e em caso assimétrico foi utilizado o modelo de distribuição gama. Resultados: No grupo Tf, a média de peso foi 966,8 (±242,2) gramas e de idade gestacional 27,70 (±2,63) semanas, no grupo NTf, estes valores foram 1214,5 (±263,8) g e 30,37 (±3,07) semanas. Houve cerca de 1,2 transfusões por paciente. Valores médios de hemoglobina das primeiras 72h de 16,65g/d e de peso de nascimento de 1184g, não se associaram a transfusões. Houve correlação entre sepse, HPIV, SDR, DBP, ECN, permanência na UTIN e óbito com transfusões de CHs. Conclusão: Menores peso de nascimento e idade gestacional asso...

Several correlations have already been described between transfusions and worse perinatal outcomes. Patients and methods: An analytical, observational, cross-sectional, cohort study performed at the Neonatal Intensive Care Unit (NICU) of the Clinical Hospital of the Botucatu Medical School, with an analysis of medical records of 170 newborns less than 1,500 g at birth admitted during the years 2015 and 2016, divided into transfused (Tf) and non-transfused (NTf) groups. Calculated difference of proportions and simple and relative frequencies; the t-student test was used for comparison between the groups, and in the case of asymmetric, the gamma distribution model was used. Results: In the Tf group, the mean weight was 966.8 (± 242.2) grams and the gestational age was 27.70 (± 2.63) weeks. In the NTf group, these values were 1214.5 (± 263, 8) grams and 30.37 (± 3.07) weeks. There were about 1.2 transfusions per patient. Mean values of hemoglobin of the first 72h of 16.65g / d and birth weight of 1184g were not associated with transfusions. There was a correlation between sepsis, IVH, RDS, BPD, NEC, NICU stay and death with RBC transfusions. Conclusion: Lower birth weight and gestational age are associated with RBC transfusions. A...
