- The complex search for the cause of gastroschisis(2022) FREITAS, Amanda Brasil de; FRANCISCO, Rossana Pulcineli Vieira; HOSHIDA, Mara Sandra; OLIVEIRA, Yanca Gasparini De; KULIKOWSKI, Leslie Domenici; BRIZOT, Maria de LourdesBackground To reveal the complex etiology of gastroschisis through two independent cases. Cases Case 1 involves gastroschisis recurrence in a consanguineous marriage, and Case 2 concerns a fetus with gastroschisis whose mother had undergone gastroplasty. Methylation array was carried out in both cases (two fetuses with gastroschisis, their two mothers, one father from the consanguineous marriage), and in 16 controls (fetuses and their respective mothers). Conclusion The two cases presented different noninherited methylation profiles.
- Pictures as mementos after perinatal death: a case study(2022) JESUS, Roberta Carolina de Almeida; BENUTE, Glaucia; BERTOLASSI, Nathalia; BARBOSA, Tercilia; BOLIBIO, Renata; FIGUEIREDO, Fernanda; SETUBAL, Maria Silvia; GIBELLI, Maria Augusta; GOMES, Ana; FERREIRA, Raquel; FRANCISCO, Rossana; BERNARDES, LisandraBackground: The grieving process following perinatal loss caused by life-limiting conditions presents some particularities associated with the family's culture and the symbolic relationship with the deceased. Objective: To reflect on the symbolic meaning attributed to mementos, particularly pictures taken immediately after birth. Method: Case study-a qualitative analysis of the data collected through semidirected interviews. Results: Of the three women that took part in the study, one woman chose not to take a picture but opted to take home the hat with her son's name on it that was provided as a regular procedure for every birth at the maternity centre. During the interview, she questioned her decision. The two other women took pictures and still look at them affectionate. One of the women keeps the picture of her child in a shrine at home, thus attributing a symbolic religious meaning to the whole experience that alleviates her pain. Conclusion: The symbolic meaning attributed to pictures of the deceased can help parents process grief.
CRIPTO-1 Is Immunolocalized in the Syncytiotrophoblast of Ampullary Pregnancies
(2022) CABAR, Fabio Roberto; PEREIRA, Pedro Paulo; BANDEIRA, Carla Leticia; BEVILACQUA, Estela; SCHULTZ, Regina; FRANCISCO, Rossana Pulcineli VieiraIntroduction. Controlling the invasive activity of trophoblastic tissue has not been elucidated. In the accreta placenta, the invasion of placental tissue is directly related to the expression of CRIPTO-1 at the maternal-fetal interface. The aim of this study is to evaluate if the expression of the CRIPTO-1 is related to different degrees of trophoblast invasion into the tube wall in ampullary pregnancy. Methods. Prospective study with 21 patients with ampullary tubal pregnancy undergoing salpingectomy. Anatomopathological evaluation determined the degree of invasion of trophoblast tissues into the tubal wall and grouped the samples into invasive degrees I, II, or III. The groups were compared for tissue expression of CRIPTO-1 using the Kruskal-Wallis nonparametric test. p values lower than 0.05 were considered significant. Results. Quantitative expression of CRIPTO-1 differed in each of the three groups of trophoblast invasion in the tubal wall in ampullary pregnancies (p < 0.001). There is a difference between groups when grade I + grade II versus grade III (p < 0.001) and grade I versus grade II + grade III (p < 0.001). The tissue expression of CRIPTO-1 in ectopic trophoblasts showed that deeper invasion of the tubal wall was associated with stronger expression than in shallow invasion (p < 0.001). Discussion. In ampullary pregnancies, the depth of penetration of trophoblast tissue in the tubal wall is related to CRIPTO-1 tissue expression.- Prevalence of oncogenic human papillomavirus in pregnant adolescents, association with colpocytological changes, risk factors and obstetric outcomes(2022) SOUZA, Henrique Diorio de; WAISSMAN, Adriana Lippi; DIORIO, Giselle Rodrigues Mota; PERES, Stela Verzinhasse; FRANCISCO, Rossana Pulcineli Vieira; GALLETTA, Marco Aurelio KnippelPurpose: The authors aim to carry out an investigation on the impact of cervical oncogenic Human Papillomavirus (HPV) detection in pregnant adolescents, to clarify the prevalence and risk factors, considering the importance and lack of data on this topic in Brazil. Methods: A cross-sectional study was conducted with adolescents receiving prenatal care in a tertiary hospital in Sao Paulo, Brazil, with routine Pap smear and oncogenic HPV detection test in the uterine cervix. The authors sought to associate the results of these tests with demographic and obstetric variables. Results: A total of 303 pregnant adolescents whose mean age was 15.30 +/- 1.22 years comprised the study subjects. The frequency of high-risk HPV cervical detection was 50.50%. Multivariate analysis revealed that a large number of partners in their lifetime (OR = 1.27) and having a religion (OR = 2.05) were risk factors for cervical detection of oncogenic HPV, while schooling appeared as a protective factor (OR = 0.85). There was an association between this detection and colpocytological alterations, reaching almost 30% of patients, but without association with obstetric and neonatal outcomes. Conclusion: The prevalence found is one of the highest in Brazil and worldwide. A greater number of partners during their lifetime and having religion were detected as possible factors associated with cervical HPV detection. Detection of cervical HPV-DNA did not influence obstetric and neonatal outcomes. The findings of this study reinforce the need to implement educational measures capable of modifying the incidence of sexually transmitted infections in this population and capable of promoting adherence to HPV vaccination programs.
- Dietary Pattern Influences Gestational Weight Gain: Results from the ProcriAr Cohort Study-Sao Paulo, Brazil(2022) SALDIVA, Silvia Regina Dias Medici; NETA, Adelia da Costa Pereira De Arruda; TEIXEIRA, Juliana Araujo; PERES, Stela Verzinhasse; MARCHIONI, Dirce Maria Lobo; CARVALHO, Mariana Azevedo; VIEIRA, Sandra Elisabete; FRANCISCO, Rossana Pulcineli VieiraThe maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) influence maternal and infant outcomes. This study identified patterns of habitual dietary intake in 385 pregnant women in Sao Paulo and explored their associations with excessive weight gain (EGWG). Weight at the first visit (<14 weeks) was used as a proxy for pre-pregnancy weight. Food consumption was assessed using the 24HR method, administered twice at each gestational trimester, and dietary patterns were identified by principal component analysis. Three dietary patterns were identified: ""Vegetables and Fruits,"" ""Western,"" and ""Brazilian Traditional."" Descriptive data analysis was performed using absolute and relative frequencies for each independent variable and multilevel mixed-effects logistic regression was used to analyze excessive gestational gain weight (EGWG) and dietary patterns (DP). The Brazilian Traditional dietary pattern showed a protective effect on EGWG (p = 0.04) and age > 35 years (p = 0.03), while subjects overweight at baseline had a higher probability of EGWG (p = 0.02), suggesting that the identification of dietary and weight inadequacies should be observed from the beginning of pregnancy, accompanied by nutritional intervention and weight monitoring throughout the gestational period to reduce risks to the mother and child's health.
- Association between preterm births and socioeconomic development: analysis of national data(2022) MONTEMOR, Marina Sanches; DEMARQUE, Gabriella Ferreira; RODRIGUES, Agatha Sacramento; FRANCISCO, Rossana Pulcinelli Vieira; CARVALHO, Mario Henrique Burlacchini deBackground The increasing prevalence of preterm birth, which is a global phenomenon, is attributable to the increased medical indications, artificial gestations, and some socioeconomic factors. This study was conducted to identify whether development and equality indices are associated with the incidence of preterm birth, specifically, spontaneous and elective preterm births. Methods This retrospective observational study comprised an analysis of data on live births from 2019 in Brazil and on socioeconomic indices that were derived from census information in 2017. Data were summarised using absolute and relative frequencies. Spearman's correlation was used to determine the correlation between socioeconomic factors and the preterm birth rate. Multiple beta regression analysis was performed to determine the best model of socioeconomic covariates and preterm birth rate. The significance level was set at 5%. Results In 2019 in Brazil, the preterm birth rate was 11.03%, of which 58% and 42% were spontaneous and elective deliveries, respectively. For all preterm births, Spearman's correlation varied from rho = 0.4 for the Gini Index and rho = - 0.24 for illiteracy. The best fit modelled the spontaneous preterm birth fraction as a negative function of the Human Development Index (HDI). The best-fit model considered the expected elective preterm birth fraction as a positive function of the HDI and as a negative function of the Gini Index, which was used as a precision parameter. Conclusions We observed a reduction in the fraction of spontaneous preterm births; however, the distribution was not uniform in the territory: higher rates of spontaneous preterm birth were noticed in the north, northeast, and mid-west regions. Thus, areas with lower education levels and inequal income distribution have a higher proportion of spontaneous preterm birth. The fraction of elective preterm birth was positively associated with more advantaged indices of socioeconomic status.
- Magnetic resonance imaging and previous cesarean section in placenta accrete spectrum disorder: Predictor model(2022) POLIZIO, Rodrigo Pamplona; YAMAUCHI, Fernando Ide; MENDES, Renata Franco Pimentel; PERES, Stela Verzinhasse; KONDO, Mario Macoto; FRANCISCO, Rossana Pulcineli VieiraObjective: To evaluate objective criteria of Magnetic Resonance Imaging (MRI) of Placenta Accreta Spectrum disorder (PAS) analyzing interobserver agreement and to derive a model including imaging and clinical variables to predict PAS. Methods: A retrospective review including patients submitted to MRI with suspicious findings of PAS on ultrasound. Exclusion criteria were lack of pathology or surgical information and missing or poor-quality MRI. Two radiologists analyzed six MRI features, and significant clinical data were also recorded. PAS confirmed on pathology or during intraoperative findings were considered positive for the primary outcome. Variables were tested through logistic regression models. Results: Final study included 96 patients with a mean age of 33 years and 73.0% of previous C-sections. All MRI features were significantly associated with PAS for both readers. After logistic regression fit, including MRI signs with a moderate or higher interobserver agreement, intraplacental T2 dark band was the most significant radiologic criteria, and ROC analysis resulted in an AUC = 0.782. After including the most relevant clinical data (previous C-section) to the model, the ROC analysis improved to an AUC = 0.893. Conclusion: Simplified objective criteria on MRI, including intraplacental T2 dark band associated with clinical information of previous C-sections, had the highest accuracy and was used for a predictive model of PAS.
- Serum vascular endothelial growth factor as a marker for tubal pregnancy(2022) CABAR, Fabio Roberto; PEREIRA, Pedro Paulo; OLIVEIRA, Matheus Abelo de; FRANCISCO, Rossana Pulcinelli VieiraOBJECTIVE: The objective of this study was to evaluate whether a single measurement of vascular endothelial growth factor could distinguish between intrauterine pregnancy and ectopic pregnancy and to correlate the levels of vascular endothelial growth factor with serum levels of progesterone and 13-human chorionic gonadotropin in each subgroup. METHODS: Ninety patients with a positive human chorionic gonadotropin test and either abdominal pain or vaginal bleeding were selected; pregnancies were singletons, spontaneously conceived, 42???56 days of gestational age. All patients had a transvaginal ultrasound examination and were divided into three subgroups: abnormal intrauterine pregnancy, tubal pregnancy, and normal intrauterine pregnancy. Tubal pregnancies were surgically treated and histologically confirmed. Blood samples were collected for the determination of 13-human chorionic gonadotropin, progesterone, and vascular endothelial growth factor and their concentrations were compared in each subgroup. Receiver operating characteristic curve was calculated by comparing the subgroup of tubal pregnancy to the other groups. A Fisher discriminant function analysis was performed. The level of significance was 5%. RESULTS: One-way analysis of variance revealed a significant correlation between the different subgroups and 13-human chorionic gonadotropin, progesterone, and vascular endothelial growth factor serum levels (p<0.001). Vascular endothelial growth factor concentration was significantly higher for patients with tubal pregnancy than for other subgroups (p<0.05). 13-Human chorionic gonadotropin and progesterone levels were higher in the subgroup with normal intrauterine pregnancies compared with the subgroups with tubal and abnormal intrauterine pregnancies (p 0.05). Serum vascular endothelial growth factor level 188.7 ng/mL predicted tubal pregnancy with 96.7% sensitivity, 95.0% specificity, 90.6% positive predictive value, and 98.3% negative predictive value. CONCLUSIONS: Serum vascular endothelial growth factor could be a marker in discriminating intrauterine pregnancy from tubal pregnancy; its levels are increased in women with ectopic pregnancy compared with women with normal and abnormal intrauterine pregnancies.
- The Influenza Vaccine May Protect Pregnant and Postpartum Women against Severe COVID-19(2022) PAGANOTI, Cristiane de Freitas; RODRIGUES, Agatha Sacramento; FRANCISCO, Rossana Pulcineli Vieira; COSTA, Rafaela Alkmin daThe SARS-CoV-2 pandemic has imposed a huge challenge on the antenatal care of pregnant women worldwide, with the maternal mortality rate being raised to alarming levels. While COVID-19 vaccines were developed, some studies highlighted a possible relationship between influenza vaccination and lower odds of COVID-19 infection. As obstetric patients belong to a high-risk group for respiratory diseases, this study evaluated whether influenza vaccination reduces the severity of COVID-19 infection and mortality among pregnant and postpartum women. We conducted a retrospective cohort study on 3370 pregnant and postpartum women from the Brazilian national database, where they were grouped according to their influenza vaccination status before the onset of COVID-19 symptoms. The intensive care unit admission and intubation rates were significantly higher among subjects in the unvaccinated group (p = 0.002 and p < 0.001, respectively). The odds of mortality risk among those who received the vaccine was 0.33, with a 95% confidence interval of 0.23-0.47. The numbers of patients who needed to be vaccinated to avoid a case of intensive care unit admission, intubation, or death due to COVID-19 were 11, 15, and 11, respectively. Influenza vaccines could confer protection against severe COVID-19 infection in pregnant and postpartum women.
- COVID-19 Vaccines Confer Protection in Hospitalized Pregnant and Postpartum Women with Severe COVID-19: A Retrospective Cohort Study(2022) PAGANOTI, Cristiane de Freitas; COSTA, Rafaela Alkmin da; PAPAGEORGHIOU, Aris T.; COSTA, Fabricio da Silva; QUINTANA, Silvana Maria; GODOI, Luciana Graziela de; MONROY, Nataly Adriana Jimenez; RODRIGUES, Agatha Sacramento; FRANCISCO, Rossana Pulcineli VieiraThe coronavirus disease 2019 (COVID-19) pandemic has had deleterious effects among the obstetric population. Pregnant and postpartum women constitute a high-risk group for severe COVID-19. Vaccination reduces the risk of infection, but it is not known whether women who become infected despite vaccination have a milder course of disease than those who had not been vaccinated. This retrospective cohort study evaluated whether vaccination reduces the severity of COVID-19 infection, as measured by severe maternal morbidity and mortality among hospitalized pregnant and postpartum individuals. A total of 2284 pregnant and postpartum women hospitalized with severe COVID-19 were included. Those who did and who did not receive COVID-19 vaccination were compared. The rates of intensive care unit admission, intubation, and mortality were significantly lower among subjects in the vaccinated group (p < 0.001, p < 0.001 and p < 0.001, respectively). The numbers of patients who needed to be vaccinated to avoid one case of intensive care unit admission, intubation, or death due to COVID-19 were 7, 7, and 9, respectively. The COVID-19 vaccine offers protective effects against intensive care unit admission, intubation, and death in hospitalized pregnant and postpartum women with severe SARS-CoV-2-induced SARS.
