Introdução: A musicoembriologia engloba a audição de música durante a gravidez, com o objetivo de melhorar a relação materno-fetal e o neurodesenvolvimento infantil. Contudo, a relação entre estes ainda não está bem estabelecida, pelo que permanece um tema controverso. Objetivo: Rever a evidência disponível sobre o impacto da audição de música durante a gravidez no neurodesenvolvimento infantil. Material e Métodos: Pesquisa de meta-análises (MA), revisões sistemáticas (RS), ensaios clínicos aleatorizados e contro- lados (ECAC), e normas de orientação clinica (NOC), em inglês e português, publicados entre 01/2004 e 04/2014, nas bases de dados Pubmed/Medline, sítios de medicina baseada na evidência e Índex de Revistas Médicas Portuguesas, utilizando os termos MeSH: music; pregnancy; child; neurodevelopment. Para a avaliação dos níveis de evidência (NE) e atribuição de forças de recomendação (FR) foi utilizada a escala SORT (Strength of Recommendation Taxonomy) da American Family Phisician. Resultados: Foram encontrados onze artigos, dos quais quatro foram selecionados: três ECAC e uma RS. Um ECAC (NE 1) mostrou melhoria significativa do comportamento neonatal nas crianças cujas mães ouviram música durante a gravidez. Outro ECAC (NE 2) demonstrou uma melhoria da relação ma- terno-fetal com a musicoembriologia. Outro ECAC (NE3) e a RS (FR B) demonstraram que o ambiente intrauterino é importante no neurodesenvolvimento neonatal, sobretudo no desenvolvi- mento do córtex cerebral motor e neurosensorial. Conclusões: A evidência disponível demonstrou que a au- dição de música durante o período embrionário apresenta benefício no neurodesenvolvimento infantil. (FR B) No entanto os estudos obtidos são em número reduzido e apresentam grande heterogeneidade em termos metodológicos. São necessários mais estudos, com populações controladas e metodologia semelhantes, para a recomendação global desta medida.

Objetivo: Identificar factores sociodemográficos y de fecundidad, asociados a ocurrencia de embarazo no deseado en mujeres colombianas en edad reproductiva en el año 2010. Métodos: Se realizó estudio retrospectivo de corte transversal, basado en los datos de la ENDS Colombia-2010, del total de mujeres en edad fértil (13-49 años) que al momento de la encuesta se encontraban en embarazo. La variable de interés fue embarazo no deseado, se describió la población a estudio y se evaluó la posible asociación con variables sociodemográficas y de fecundidad, a través de análisis bivariado y multivariado. Se realizaron los mismos análisis por grupo de edad (adolescentes vs adultas). Resultados: La prevalencia de embarazo no deseado en las mujeres colombianas en el 2010 fue de 61,4 %. De acuerdo al modelo de regresión logística, no estar en unión a una pareja (OR: 4,01 IC95%: 3,066-5,269), tener hijos (OR: 2,040 IC95%: 1,581 – 2,631), estar en el quintil de menor riqueza (OR: 2,137 IC95%: 1,328-3,440), y ser adolescente (OR: 1,599 IC95%: 1,183-2,162), son factores que aumentan la probabilidad de tener un embarazo no deseado. Se encontraron diferencias en los factores asociados al realizar segmentación por edad. Conclusiones: La prevalencia de embarazo no deseado permanece alta en Colombia respecto a años anteriores y a otros países. Los resultados pueden ser de utilidad para el desarrollo de políticas en salud sexual y reproductiva teniendo en cuenta los factores asociados identificados priorizando a la población adolescente y de menor estatus socioeconómico, para la prevención de embarazo no deseado en Colombia.

A paca é um roedor sul-americano cujo manejo, tranqüilização ou anestesia oferece um grande campo de pesquisa devido aos poucos artigos existentes. Doze pacas fêmeas adultas foram utilizadas, mantidas separadas em seis baias, sendo capturadas com um puçá de polipropileno e levadas a uma sala na qual se realizava a tricotomia abdominal. Após, os animais eram colocados em uma gaiola de ferro de compressão lateral. A sessão de ultra-sonografia era realizada em modo B com um transdutor setorial eletrônico de 5,0 e 7,5 MHz. Para a diminuição do estresse causado pelos procedimentos, a tranqüilização das fêmeas era realizada com diazepam e maleato de midazolam por via oral. Ambos demonstraram-se efetivos na tranqüilização das pacas previamente e durante as sessões, sendo que o maleato de midazolam proporcionou um melhor manejo dos animais.

Background: the paca is a South American rodent with potential as a commercial food animal. We examined paca placenta as part of a wider effort to understand the reproductive biology of this species.Methods: Thirteen specimens between midgestation and term of pregnancy were studied by light and transmission electron microscopy.Results: the placenta is divided into several lobes separated by interlobular trophoblast. Maternal arterial channels and fetal veins are found at the centre of each lobe. In the labyrinth, maternal blood flows through trophoblast-lined lacunae in close proximity to the fetal capillaries. The interhaemal barrier is of the haemomonochorial type with a single layer of syncytiotrophoblast. Caveolae occur in the apical membrane of the syncytiotrophoblast and recesses in the basal membrane, but there is no evidence of transtrophoblastic channels. The interlobular areas consist of cords of syncytiotrophoblast defining maternal blood channels that drain the labyrinth. Yolk sac endoderm covers much of the fetal surface of the placenta. The subplacenta comprises cytotrophoblast and syncytiotrophoblast. There are dilated intercellular spaces between the cytotrophoblasts and lacunae lined by syncytiotrophoblast. In the junctional zone between subplacenta and decidua, there are nests of multinucleated giant cells with vacuolated cytoplasm. The entire placenta rests on a pedicle of maternal tissue. An inverted yolk sac placenta is also present. The presence of small vesicles and tubules in the apical membrane of the yolk sac endoderm and larger vesicles in the supranuclear region suggest that the yolk sac placenta participates in maternal-fetal transfer of protein.Conclusion: the paca placenta closely resembles that of other hystricomorph rodents. The lobulated structure allows for a larger exchange area and the development of precocial young.

Bisphenol-A (BPA) is one of the most widespread EDCs used as a base compound in the manufacture of polycarbonate plastics. The aim of our research has been to study how the exposure to BPA during pregnancy affects weight, glucose homeostasis, pancreatic β-cell function and gene expression in the major peripheral organs that control energy flux: white adipose tissue (WAT), the liver and skeletal muscle, in male offspring 17 and 28 weeks old. Pregnant mice were treated with a subcutaneous injection of 10 µg/kg/day of BPA or a vehicle from day 9 to 16 of pregnancy. One month old offspring were divided into four different groups: vehicle treated mice that ate a normal chow diet (Control group); BPA treated mice that also ate a normal chow diet (BPA); vehicle treated animals that had a high fat diet (HFD) and BPA treated animals that were fed HFD (HFD-BPA). The BPA group started to gain weight at 18 weeks old and caught up to the HFD group before week 28. The BPA group as well as the HFD and HFD-BPA ones presented fasting hyperglycemia, glucose intolerance and high levels of non-esterified fatty acids (NEFA) in plasma compared with the Control one. Glucose stimulated insulin release was disrupted, particularly in the HFD-BPA group. In WAT, the mRNA expression of the genes involved in fatty acid metabolism, Srebpc1, Pparα and Cpt1β was decreased by BPA to the same extent as with the HFD treatment. BPA treatment upregulated Pparγ and Prkaa1 genes in the liver; yet it diminished the expression of Cd36. Hepatic triglyceride levels were increased in all groups compared to control. In conclusion, male offspring from BPA-treated mothers presented symptoms of diabesity. This term refers to a form of diabetes which typically develops in later life and is associated with obesity.

Maternal high-fat diet (HFD) impairs hippocampal development of offspring promoting decreased proliferation of neural progenitors, in neuronal differentiation, in dendritic spine density and synaptic plasticity reducing neurogenic capacity. Notch signaling pathway participates in molecular mechanisms of the neurogenesis. The activation of Notch signaling leads to the upregulation of Hes5, which inhibits the proliferation and differentiation of neural progenitors. This study aimed to investigate the Notch/Hes pathway activation in the hippocampus of the offspring of dams fed an HFD. Female Swiss mice were fed a control diet (CD) and an HFD from pre-mating until suckling. The bodyweight and mass of adipose tissue in the mothers and pups were also measured. The mRNA and protein expression of Notch1, Hes5, Mash1, and Delta1 in the hippocampus was assessed by RT-PCR and western blotting, respectively. Dams fed the HFD and their pups had an increased bodyweight and amount of adipose tissue. Furthermore, the offspring of mothers fed the HFD exhibited an increased Hes5 expression in the hippocampus compared with CD offspring. In addition, HFD offspring also expressed increased amounts of Notch1 and Hes5 mRNA, whereas Mash1 expression was decreased. However, the expression of Delta1 did not change significantly. We propose that the overexpression of Hes5, a Notch effector, downregulates the expression of the proneural gene Mash1 in the offspring of obese mothers, delaying cellular differentiation. These results provide further evidence that an offspring's hippocampus is molecularly susceptible to maternal HFD and suggest that Notch1 signaling in this brain region is important for neuronal differentiation.

Objective. To assess the relationship between cortisol concentrations in the last trimester of pregnancy and systemic vascular resistance — SVR in childhood. Materials and methods. This study is part of a cohort involving 130 Brazilian pregnant women and their children, ages 5 to 7 years. Maternal cortisol was determined in saliva by an enzyme immunoassay utilizing the mean concentration of 9 samples of saliva (3 in each different day), collected at the same time, early in the morning. SVR was assessed by the HDI/PulseWave CR-2000 Cardiovascular Profiling System®. Socioeconomic and demographic characteristics and life style factors were determined by a questionnaire. The nutritional status of the women and children was assessed by the body mass index — BMI. The association between maternal cortisol and SVR in childhood was calculated by multivariate linear regression analysis. Results.There were statistically significant associations between maternal cortisol and SVR (p = 0.043) and BMI-z score of the children (p = 0.027), controlling for maternal BMI, birth weight, age, and gender of the children. Conclusion. As far as we know this is the first study in the literature assessing the association between cortisol concentrations in pregnancy and SVR in childhood. Overall, the data suggest that exposure to excess glucocorticoid in the prenatal period is associated to vascular complications in childhood, predisposing to cardiovascular diseases in later life

The occurrence of chronic myeloid leukemia in pregnancy is rare and its management poses a clinical challenge for physicians treating these patients. We report a 30-year-old woman with chronic myeloid leukemia who became pregnant twice successfully. Philadelphia-positive CML in its chronic phase was diagnosed at 16 weeks of her first gestation. At that time, she received no treatment throughout her pregnancy. At 38 weeks of gestation, a normal infant was delivered by cesarean section. At six weeks postpartum, the patient underwent imatinib mesylate therapy but she could not tolerate the treatment. The treatment was then changed to nilotinib at 400 mg orally b.i.d. Two years later, she became pregnant again while she was on nilotinib 200 mg b.i.d. The unplanned pregnancy was identified during her 7.4 weeks of gestation. Because the patient elected to continue her pregnancy, nilotinib was stopped immediately, and no further treatment was given until delivery. Neither obstetrical complications nor structural malformations in neonates in both pregnancies were observed. Both babies' growth and development have been normal. Although this experience is limited to a single patient, the success of this patient demonstrates that the management of chronic myeloid leukemia in pregnant women may be individualized based on the relative risks and benefits of the patient and fetus.

Background: Placentas of guinea pig-related rodents are appropriate animal models for human placentation because of their striking similarities to those of humans. To optimize the pool of potential models in this context, it is essential to identify the occurrence of characters in close relatives. Methods: In this study we first analyzed chorioallantoic placentation in the prea, Galea spixii, as one of the guinea pig's closest relatives. Material was collected from a breeding group at the University of Mossoro, Brazil, including 18 individuals covering an ontogenetic sequence from initial pregnancy to term. Placentas were investigated by means of histology, electron microscopy, immunohistochemistry (vimentin, alpha-smooth muscle actin, cytokeration) and proliferation activity (PCNA). Results: Placentation in Galea is primarily characterized by an apparent regionalization into labyrinth, trophospongium and subplacenta. It also has associated growing processes with clusters of proliferating trophoblast cells at the placental margin, internally directed projections and a second centre of proliferation in the labyrinth. Finally, the subplacenta, which is temporarily supplied in parallel by the maternal and fetal blood systems, served as the center of origin for trophoblast invasion. Conclusion: Placentation in Galea reveals major parallels to the guinea pig and other caviomorphs with respect to the regionalization of the placenta, the associated growing processes, as well as trophoblast invasion. A principal difference compared to the guinea pig occurred in the blood supply of the subplacenta. Characteristics of the invasion and expanding processes indicate that Galea may serve as an additional animal model that is much smaller than the guinea pig and where the subplacenta partly has access to both maternal and fetal blood systems.
