Diabetes in Pregnancy and Hemoglobin A1c
Introdução: Há estudos que revelam que a Hemoglobina A1c (HbA1c) é um indicador confiável do controlo glicémico em grávidas com diabetes gestacional (DG).
Objetivo: Relacionar os níveis de HbA1c no terceiro trimestre e o prognóstico materno-fetal.
Tipo de estudo: Retrospetivo.
População: Quatrocentos e setenta e quatro mulheres vigiadas na consulta de diabetes e gravidez com o diagnóstico de DG.
Métodos: Dividiu-se a população em dois grupos: HbA1c <6% (grupo um) e HbA1c ≥6%
(grupo dois). Foram avaliados: fatores de risco para diabetes gestacional, ganho de peso na gravidez, idade gestacional (IG) do diagnóstico, complicações na gravidez, administração de insulina, IG no parto, peso ao nascer e resultado do rastreio pós-parto.
Resultados: No grupo um obteve-se 420 mulheres e no grupo dois 54. O grupo dois havia mulheres com maior IMC (27 vs 29 kg / cm2; p-value 0,007), história pessoal de diabetes gestacional(14,3% vs 27,6%; p-value 0,004) e macrossomia prévia (7,6% vs 14,8%; p-value 0,039). Neste mesmo grupo uma maior percentagem de grávidas efetuou insulina (28,6% vs 48,1%; p-value 0,005) e apresentou maior ganho de peso durante a gravidez (24,8% vs 55,6%; p-value 0,000). Verificou-se um maior número de casos de recém-nascidos grandes para a IG (6,7% vs 20,4%; p-value = 0,002) e uma maior percentagem de mulheres apresentou alteração no rastreio pós-parto (15,8% vs 47,5%; p-value = 0,000).
Conclusões: As mulheres com valores de HbA1c ≥6% são mais pesadas, com história pessoal
de DG e macrossomia prévia, mais frequentemente necessitaram de terapêutica com insulina e apresentam maior ganho de peso. Verificou-se um maior número de casos de recém-nascidos grandes para a IG e uma maior percentagem de mulheres apresentou alteração no rastreio pós-parto
Diabetes in Pregnancy - Postpartum Screening
Introdução: Um terço das mulheres com diabetes gestacional terá o diagnóstico de diabetes ou alteração do metabolismo da glicose no rastreio pós-parto.
Objectivo: Avaliar a percentagem de mulheres submetidas a rastreio pós-parto e associar o resultado com a história materna.
Métodos: Estudo retrospectivo de 1013 gravidezes com diabetes gestacional (2005-2009). Dividiu-se a população em dois grupos de acordo com o resultado: normal (grupo 1) e com diabetes ou alteração do metabolismo da glicose (grupo 2). Para ambos os grupos
foram avaliados: idade materna, índice de massa corporal, ganho de peso na gravidez, idade gestacional do diagnóstico, necessidade
de administração de insulina, factores de risco para diabetes gestacional e peso do recém-nascido.
Resultados: O rastreio pós-parto foi realizado em 76,8% das mulheres (n=778). O teste foi considerado normal (grupo 1) em 628 mulheres(80,7%) e alterado (grupo 2) em 150 mulheres (19,3%). O Grupo 2 teve mulheres mais velhas (idade média de 34 vs 33 anos;p-value 0,013), com maior índice de massa corporal (28,5 vs 25,8kg / cm2; p-value 0,000), maior número de mulheres com história familiar em primeiro grau de diabetes mellitus (50,3% vs 39,9%; p-value 0,026) e história pessoal de macrossomia prévia (12,1% vs 5,4%; p-value 0,003). O diagnóstico mais precoce da diabetes gestacional foi também feito nesse grupo (27 vs 31 semanas; p-value 0,000) e uma maior percentagem efectuou insulina (41% vs 15%; p-value 0,000), tendo iniciado mais cedo a sua administração (28 vs 30 semanas; p-value 0,010). Verificou-se uma maior percentagem de grávidas multíparas no grupo 2 (64% vs 49,4%; p-value = 0,001) e um maior número de casos de recém-nascidos grandes para a idade gestacional (17,1% vs 8,3%; p-value = 0,001). A história pessoal de diabetes gestacional e ganho de peso durante a gestação foi semelhante nos dois grupos.
Conclusões: As mulheres com alteração nos resultados do rastreio pós-parto são geralmente mais velhas, mais pesadas, multíparas, com história familiar em primeiro grau de diabetes Mellitus e história pessoal de macrossomia prévia. O diagnóstico de diabetes gestacional foi mais precoce neste grupo, mais frequentemente necessitaram de terapêutica com insulina com início mais cedo e verificou-se um maior número de recém-nascidos grandes para a idade gestacional
Extraperitoneal Leiomyoma of the Round Ligament. Case Report
Fibromyoma of the round ligament should be considered as a possible etiology for a large preperitoneal tumor. We report a case of a 44-year-old female who was found to have a fibroleiomyoma that measured 14 cm, weighed 3599 gr and had grown in the abdominal wall between the muscle and the peritoneum, taking as its starting point the right round ligament
First Trimester Prediction of Pre-Eclampsia in Low Risk Pregnancies: Determining the Cut-Off in a Portuguese Group
Objective:We aimed to identify the cut-off for risk of pre-eclampsia (PE) in Portuguese population by applying the first trimester prediction model from Fetal Medicine Foundation (FMF) in a prospective enrolled cohort of low risk pregnant women.
Population and methods: A prospective cohort of low risk singleton pregnancies underwent routine first-trimester scree -
ning from 2011 through 2013. Maternal characteristics, blood pressure, uterine artery Doppler, levels of pregnancy-associated plasma protein-A (PAPP-A) and free b-human chorionic gonadotropin were evaluated. The prediction of PE in first trimester was calculated through software Astraia, the outcome obtained from medical records and the cutoff value was subse quently calculated.
Results:Of the 273 enrolled patients, 7 (2.6%) developed PE. In first trimester women who developed PE presented higher uterine arteries resistance, represented by higher values of lowest and mean uterine pulsatility index, p <0.005. There was no statistical significance among the remaining maternal characteristics, body mass index, blood pressure and PAPP-A. Using the FMF first trimester PE algorithm, an ideal cut-off of 0.045 (1/22) would correctly detect 71% women who developed PE for a 12% false positive rate and a likelihood ratio of 12.98 (area under the curve: 0.69; confidence interval 95%: 0.39-0.99). By applying the reported cutoff to our cohort, we would obtain 71.4% true positives, 88.3% true negatives, 11.4% false positives and 28.6% false negatives.
Conclusion: By applying a first trimester PE prediction model to low risk pregnancies derived from a Portuguese population, a significant proportion of patients would have been predicted as high risk. New larger studies are required to confirm the present findings
Apresentação Pélvica: Parto Vaginal Versus Cesariana, Qual a Melhor Intervenção?
INTRODUCTION:
The best route of delivery for the term breech fetus is still controversial. We aim to compare maternal and neonatal outcomes between vaginal and cesarean term breech deliveries.
MATERIAL AND METHODS:
Multicentric retrospective cohort study of singleton term breech fetuses delivered vaginally or by elective cesarean section from January 2012 - October 2014. Primary outcomes were maternal and neonatal morbidity or mortality.
RESULTS:
Sixty five breech fetuses delivered vaginally were compared to 1262 delivered by elective cesarean. Nulliparous women were more common in the elective cesarean group (69.3% vs 24.6%; p < 0.0001). Gestational age at birth was significantly lower in the vaginal delivery group (38 ± 1 weeks vs 39 ± 0.8 weeks; p = 0.0029) as was birth weight (2928 ± 48.4 g vs 3168 ± 11.3 g; p < 0.0001). Apgar scores below seven on the first and fifth minutes were more likely in the vaginal delivery group (1st minute: 18.5% vs 5.9%; p = 0.0006; OR 3.6 [1.9 - 7.0]; 5th minute: 3.1% vs 0.2%; p = 0.0133; OR 20.0 [2.8 - 144.4]), as was fetal trauma (3.1% vs 0.3%: p = 0.031; OR 9.9 [1.8-55.6]). Neither group had cases of fetal acidemia. Admission to the Neonatal Intensive Care Unit, maternal postpartum hemorrhage and the incidence of other obstetric complications were similar between groups.
DISCUSSION:
Although vaginal breech delivery was associated with lower Apgar scores and higher incidence of fetal trauma, overall rates of such events were low. Admission to the neonatal intensive care unit and maternal outcomes were similar.
CONCLUSION:
Both delivery routes seem equally valid, neither posing high maternal or neonatal complications' incidence.info:eu-repo/semantics/publishedVersio

Comprehensive genetic dissection of wood properties in a widely-grown tropical tree: Eucalyptus
Background: Eucalyptus is an important genus in industrial plantations throughout the world and is grown for use as timber, pulp, paper and charcoal. Several breeding programmes have been launched worldwide to concomitantly improve growth performance and wood properties (WPs). In this study, an interspecific cross between Eucalyptus urophylla and E. grandis was used to identify major genomic regions (Quantitative Trait Loci, QTL) controlling the variability of WPs. Results: Linkage maps were generated for both parent species. A total of 117 QTLs were detected for a series of wood and end-use related traits, including chemical, technological, physical, mechanical and anatomical properties. The QTLs were mainly clustered into five linkage groups. In terms of distribution of QTL effects, our result agrees with the typical L-shape reported in most QTL studies, i.e. most WP QTLs had limited effects and only a few (13) had major effects (phenotypic variance explained > 15%). The co-locations of QTLs for different WPs as well as QTLs and candidate genes are discussed in terms of phenotypic correlations between traits, and of the function of the candidate genes. The major wood property QTL harbours a gene encoding a Cinnamoyl CoA reductase (CCR), a structural enzyme of the monolignol-specific biosynthesis pathway. Conclusions: Given the number of traits analysed, this study provides a comprehensive understanding of the genetic architecture of wood properties in this Eucalyptus full-sib pedigree. At the dawn of Eucalyptus genome sequence, it will provide a framework to identify the nature of genes underlying these important quantitative traits. (Résumé d'auteur
