BACKGROUND AND OBJECTIVE: Gastroschisis is a congenital anomaly with increasing incidence, easy prenatal diagnosis and extremely variable postnatal outcomes. Our objective was to systematically review the evidence regarding the association between prenatal ultrasound signs (intraabdominal bowel dilatation [IABD], extraabdominal bowel dilatation, gastric dilatation [GD], bowel wall thickness, polyhydramnios, and small for gestational age) and perinatal outcomes in gastroschisis (bowel atresia, intra uterine death, neonatal death, time to full enteral feeding, length of total parenteral nutrition and length of in hospital stay). METHODS: Medline, Embase, and Cochrane databases were searched electronically. Studies exploring the association between antenatal ultrasound signs and outcomes in gastroschisis were considered suitable for inclusion. Two reviewers independently extracted relevant data regarding study characteristics and pregnancy outcome. All meta-analyses were computed using individual data random-effect logistic regression, with single study as the cluster unit. RESULTS: Twenty-six studies, including 2023 fetuses, were included. We found significant positive associations between IABD and bowel atresia (odds ratio [OR]: 5.48, 95% confidence interval [CI] 3.1-9.8), polyhydramnios and bowel atresia (OR: 3.76, 95% CI 1.7-8.3), and GD and neonatal death (OR: 5.58, 95% CI 1.3-24.1). No other ultrasound sign was significantly related to any other outcome. CONCLUSIONS: IABD, polyhydramnios, and GD can be used to an extent to identify a subgroup of neonates with a prenatal diagnosis of gastroschisis at higher risk to develop postnatal complications. Data are still inconclusive on the predictive ability of several signs combined, and large prospective studies are needed to improve the quality of prenatal counseling and the neonatal care for this condition.

O timo é uma pequena glândula responsável pela produção de linfócitos T, importante na resposta imunitária do organismo. É órgão relativamente grande no período perinatal e pode estender-se superiormente, atingindo o pescoço, com variantes anatômicas. É possível identificar o timo normal, por meio da ultra-sonografia, pelo acesso supra-esternal, paraesternal e esternal e também na região cervical quando em localização atípica. A partir do início da puberdade, devido à sua involução com diminuição progressiva do seu tamanho e porque o pulmão aerado se interpõe entre o timo e o feixe sonoro, a sua visualização é mais difícil. O padrão da ecotextura normal tímica é característica: hipoecogênico em relação ao parênquima normal da tireóide e apresenta múltiplas estruturas ecogênicas lineares e focais, dispersas pelo parênquima, que correspondem aos septos e vasos sanguíneos. O reconhecimento pela ultra-sonografia de tecido tímico pode ser importante para evitar investigações desnecessárias ou cirurgias num timo normal que mimetiza massa patológica.

OBJETIVO: Analisar, prospectivamente, o índice de líquido amniótico em gestantes de baixo risco que apresentaram ou não complicações da gestação e do período perinatal. MATERIAIS E MÉTODOS: Foi estudado, de modo prospectivo, o índice de líquido amniótico de 45 primigestas sem doenças no momento da inclusão no estudo. O índice foi avaliado em quatro períodos da gestação - 18-20, 24-26, 28-30 e 34-36 semanas - e seus valores foram correlacionados com o surgimento de complicações gestacionais e perinatais, Doppler das artérias uterinas, idade gestacional ao parto, vias de parto e o peso dos recém-nascidos. RESULTADOS: O índice de líquido amniótico não mostrou diferença estatística entre as pacientes com gestações normais e complicadas em nenhum dos quatro períodos estudados. Também não mostrou associação com a idade gestacional ao parto, as vias de parto e o peso dos recém-nascidos. Observou-se que a média do índice de líquido amniótico entre 28-30 semanas é mais elevada (p = 0,004) nas pacientes com incisura bilateral do que nas com Doppler normal. CONCLUSÃO: A avaliação prospectiva do índice de líquido amniótico em gestações de baixo risco parece não ser um bom preditor de complicações gestacionais ou perinatais.

Exiting from the largely sterile environment of the womb, the neonatal immune system is not fully mature, and thus neonatal immune cells must simultaneously mount responses against environmental stimuli while maturing. This dynamic process of immune maturation is driven by a variety of cell-intrinsic and extrinsic factors. Recent studies have focused on some of these factors and have shed light on the mechanisms by which they drive immune maturation. We review the interactions and consequences of immune maturation during the pre- and perinatal period. We discuss environmental signals in early life that are needed for healthy immune homeostasis, and highlight detrimental factors that can set an individual on a path towards disease. This early-life period of immune maturation could hold the key to strategies for setting individuals on trajectories towards health and reduced disease susceptibility.

Objective: To summarise and critically evaluate the evidence informing the provision of standard care practices and psychosocial interventions following stillbirth. Background: Stillbirth is increasingly recognised as a significant bereavement experience with the potential to cause substantial psychological distress for parents. Standard care practices and psychosocial interventions to support parents have undergone dramatic changes, with limited basis in evidence. Methods: A systematic narrative review was conducted of quantitative studies examining interventions designed to reduce psychological distress in parents following the loss of a stillborn baby. Results: Twenty-five studies met the inclusion criteria for the review. Substantial methodological weaknesses were identified among reviewed studies, including small and heterogeneous loss samples, weak study designs and lack of clarity in reported methods and outcomes. Inadequate replication of many findings substantially limits the generalisability of the evidence. Conclusion: Tentative evidence was found for the provision of mementoes of the baby and information regarding the cause of the loss, support group attendance, and cognitive behavioural interventions for parents identified with clinical levels of distress. Contradictory findings for the impact of contact with the baby prevent the formation of clear conclusions for this practice. Due to the methodological weaknesses prevalent in the research identified, the current evidence base is not considered sufficiently able to reliably inform care practices and intervention approaches. High-quality research evidence in this field is urgently required.

OBJETIVO: Avaliar índices de pulsatilidade das artérias umbilical (IPAU) e cerebral média (IPACM) e relação do índice de pulsatilidade umbilico-cerebral (IPAU/IPACM) em fetos de gestantes hipertensas e presença de resultados perinatais adversos. MATERIAIS E MÉTODOS: Analisamos IPAU, IPACM e IPAU/IPACM de 289 fetos de gestantes hipertensas quanto à previsão dos resultados perinatais adversos. Os resultados foram comparados sem e com ajuste pela idade gestacional. RESULTADOS: O índice de Apgar < 7 no 5º minuto foi associado com resultados alterados após o ajuste por idade gestacional. O risco para recém-nascidos pequenos para a idade gestacional aumentou em três vezes após o ajuste, com significância estatística em todos os parâmetros do Doppler. Na síndrome da hipóxia neonatal o aumento do risco ajustado pela idade gestacional foi estatisticamente significante no IPAU e IPAU/IPACM. Não houve aumento no risco de síndrome do desconforto respiratório na análise ajustada. A mortalidade perinatal e o IPAU alterado apresentaram um risco três vezes maior e foram estatisticamente significantes após o ajuste. CONCLUSÃO: Em gestantes hipertensas, o IPAU apresentou melhor correlação com os resultados perinatais do que o IPACM ou relação IPAU/IPACM. O risco de resultados adversos deve considerar a idade gestacional.

INTRODUCTION: Cerebral palsy (CP) is the most common physical disability in childhood. It is a disorder resulting from sensory and motor impairments due to perinatal brain injury, with lifetime consequences that range from poor adaptive and social function to communication and emotional disturbances. Infants with CP have a fundamental disadvantage in recovering motor function: they do not receive accurate sensory feedback from their movements, leading to developmental disregard. Constraint-induced movement therapy (CIMT) is one of the few effective neurorehabilitative strategies shown to improve upper extremity motor function in adults and older children with CP, potentially overcoming developmental disregard. METHODS AND ANALYSIS: This study is a randomised controlled trial of children 12-24 months corrected age studying the effectiveness of CIMT combined with motor and sensory-motor interventions. The study population will comprise 72 children with CP and 144 typically developing children for a total of N=216 children. All children with CP, regardless of group allocation will continue with their standard of care occupational and physical therapy throughout the study. The research material collected will be in the form of data from high-density array event-related potential scan, standardised assessment scores and motion analysis scores. ETHICS AND DISSEMINATION: The study protocol was approved by the Institutional Review Board. The findings of the trial will be disseminated through peer-reviewed journals and scientific conferences. TRIAL REGISTRATION NUMBER: NCT02567630.

OBJETIVO: Identificar a prevalência de malformações congênitas do sistema nervoso central (SNC) e malformações associadas diagnosticadas pela ultrassonografia obstétrica. MATERIAIS E MÉTODOS: Estudo observacional, transversal, descritivo, em instituição de referência para gestações de alto risco. RESULTADOS: Malformações congênitas do SNC estiveram presentes sem outras malformações associadas em 65,78%, com a distribuição: hidrocefalia (37,5%), mielomeningocele (15%), encefalocele (12,5%), agenesia de corpo caloso (12,5%), anencefalia (12,5%), holoprosencefalia (7,5%), Dandy-Walker (7,5%), Arnold-Chiari (5,0%), hidranencefalia (5,0%), meningocele (5,0%), cisto aracnoideo (2,5%). Malformações congênitas de outros sistemas estiveram associadas às do SNC: craniofacial (73,9%), ortopédica (65,2%), cardiovascular (34,8%), geniturinária (30,4%), gastrintestinal (30,4%), respiratória (8,7%), sindrômica (8,7), oftalmológica (4,3%). A sensibilidade ultrassonográfica no estudo de malformações fetais do SNC foi 79,4%. A taxa de falso-negativos foi 20,5%. Dentre as limitações quantificáveis destaca-se o oligodrâmnio, presente em 25% dos falso-negativos. CONCLUSÃO: A ultrassonografia obstétrica possui boa sensibilidade no rastreio de malformações fetais do SNC, em especial com o aperfeiçoamento constante e domínio na utilização de métodos especializados, como o Doppler e a ultrassonografia volumétrica (3D/4D), contribuindo para firmar-se como modalidade de escolha nesta rotina. Complementar ao método, a ressonância magnética pode vir a fornecer subsídios para uma ainda melhor assistência perinatal.

Perinatal asphyxia induces neuronal cell death and brain injury, and is often associated with irreversible neurological deficits in children. There is an urgent need to elucidate the neuronal death mechanisms occurring after neonatal hypoxia-ischemia (HI). We here investigated the selective neuronal deletion of the Atg7 (autophagy related 7) gene on neuronal cell death and brain injury in a mouse model of severe neonatal hypoxia-ischemia. Neuronal deletion of Atg7 prevented HI-induced autophagy, resulted in 42% decrease of tissue loss compared to wild-type mice after the insult, and reduced cell death in multiple brain regions, including apoptosis, as shown by decreased caspase-dependent and -independent cell death. Moreover, we investigated the lentiform nucleus of human newborns who died after severe perinatal asphyxia and found increased neuronal autophagy after severe hypoxic-ischemic encephalopathy compared to control uninjured brains, as indicated by the numbers of MAP1LC3B/LC3B (microtubule-associated protein 1 light chain 3)-, LAMP1 (lysosomal-associated membrane protein 1)-, and CTSD (cathepsin D)-positive cells. These findings reveal that selective neuronal deletion of Atg7 is strongly protective against neuronal death and overall brain injury occurring after HI and suggest that inhibition of HI-enhanced autophagy should be considered as a potential therapeutic target for the treatment of human newborns developing severe hypoxic-ischemic encephalopathy.

There are not enough previous publications which are focused on mothers with well-controlled gestational diabetes mellitus (GDM) as a risk factor that determines the occurrence of neonatal hypoglycemia. In addition, approaches to blood glucose monitoring have been inconsistent and poorly defined. Our objective is to determine if being a newborn from a mother with well-controlled gestational diabetes (regardless insulin treatment) have a higher risk to develop hypoglycemia than a healthy newborn, using a defined and strict protocol. The project will take place in a regional hospital of Girona. We will recruit from 2014 to 2015 a cohort of 623 infants born in this center without any malformation or any perinatal pathology or complication, selected with a consecutive sampling. We will record sex, ethnicity and gestational age information. We will measure blood glucose levels and anthropometric measurements in newborns always taking into account the presence of well-controlled maternal gestational diabetes or not. Patients will be followed up during 24 hours to determine the incidence of hypoglycemia. We will analyze the contribution between exposure factors that we have studied and the incidence of the outcome using a multivariate analysis

Intrauterine growth restriction (IUGR) is one of the leading causes of perinatal mortality and morbidity. Nowadays, this condition is detected in the 3rt and last trimester of gestation when the pathology is already established and success of therapeutic strategies are limited. As the physiopathology of the disease suggests that the problem stems from poor placental implantation, it would be quite advantageous to identify women at increased risk in the first or second trimester of gestation because it then might be possible to offer treatment interventions or at least to establish increased surveillance for high risk pregnancies. Maternal levels of pregnancy-associated plasma protein-A (PAPP-A) and free β human chorionic gonadotropin (free βhCG) has been shown to be effective in first trimester screening for chromosomal abnormalities, primarily trisomies 21, 13 and 18. Previous studies evaluating PAPP-A and free βhCG measured in the first trimester in relation with IUGR have provided conflicting results. Moreover, it has been suggested that black ethnicity is another important predictive factor for fetal growth restriction.Objective: To analyse the association between first trimester serum analytes (PAPP-A and free βhCG) and ethnicity with Intrauterine Growth Restriction.Methods: The study consists in a retrospective cohort, including all singleton pregnancies with complete outcome data that had undergone first trimester screening (PAPP-A and free βhCG) at 11-13+6weeks of gestation between 1/1/2010 - 31/12/2012 in Hospital Universitari Dr Josep Trueta. Biochemical markers are converted to multiples of the median (MoMs) and percentiles 5 and 10 are calculated. The association between free βhCG and PAPP-A with the incidence of IUGR is evaluated in combination with maternal ethnicity. Bivariate and logistic regression analyses are performed to adjust this association for co variables

Aquest Projecte Fi de Carrera consisteix en l’elaboració d’un projecte per poder realitzar la implantació d’un centre de repoblació de llamàntols del mediterrani i contribuir en el restabliment de l’equilibri de crustacis marins a la costa de Menorca. El centre de repoblació s’ubica en una piscifartoria de cria de llobarros i aurades actualment tancada a ‘Sa Caleta de Binillautí’ de Menorca. Es realitza la reforma pertinent de les instal·lacions i edificacions existent per adaptar-les al cultiu del llamàntol. El procés aqüícola consisteix en agafar llamàntols femella gràvides del medi, els ous s’eclosionen i s’obtenen les larves de llamàntol en condicions controlades. D’aquesta manera s’augmenta la taxa de supervivència de les larves. Aquestes es preengreixen en el viver i s’obtenen les postlarves d’últim estadi aptes per engreixar-les en les muscleres del port de Maó. Finalment aquestes postlarves o juvenils serveixen per repoblar la costa del mar de Menorca. Ha estat indispensable l’elaboració d’una memòria, uns annexes relacionats amb la memòria, el plec de condicions, uns plànols i un pressupost. Dins del projecte s’ha de destacar la importància de les particularitats del cultiu del llamàntol, les instal·lacions de subministrament d’aigua marina i l’estudi de viabilitat realitzat.
