- 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.
- Placental pathological findings in coronavirus disease 2019: Perinatal outcomes(2022) ARCOS JUNIOR, Gelson Farias; FRANCISCO, Rossana Pulcineli Vieira; KILL, Beatriz; PERES, Stela Verzinhasse; GIBELLI, Maria Augusta B. C.; IBIDI, Silvia Maria; CARVALHO, Werther Brunow de; SIMOES, Angelica Braz; BRIZOT, Maria de Lourdes; SCHULTZ, Regina; CARVALHO, Mariana AzevedoIntroduction: Placental alterations caused by severe acute respiratory coronavirus-2 (SARS-CoV-2) infection have already been described, but most studies used small sample groups and the difference according to the severity of the disease has not been verified. Our objective was to describe placental alterations in patients with coronavirus disease 2019 (COVID-19) and analyze the association of pathological placental findings with the clinical pa-rameters of COVID-19 and perinatal results.Methods: This was a nested study within a prospective cohort study involving 109 symptomatic pregnant women with COVID-19. The prevalence of observed placental alterations was described, and the associations of path-ological findings with the clinical parameters of COVID-19 severity and with perinatal outcomes were assessed.Results: The frequency of types of placental features was poor maternal vascular perfusion in 45% of cases, poor fetal vascular perfusion in 33.9%, hematogenous origin infection in 32.1%, and morphological changes corre-sponding to ascending infection in 21.1%. Hematogenous infection differed significantly according to COVID-19 severity (p = 0.008), with a prevalence ratio (PR) of 1.74 (95% confidence interval, 1.02-2.98) in the moderate COVID-19 group compared to the mild COVID-19 group. Among the perinatal outcomes, there was an unex-pected inverse association between prematurity and placental infection of hematogenous origin, with lower rates of prematurity among cases with inflammation of hematogenous origin (p = 0.029).Discussion: Moderate SARS-Cov-2 infection presented a higher prevalence of placental pathological findings. There was no association of placental findings with adverse perinatal outcomes.
- Bacteriuria in Pregnant Adolescents and Behavioral Risk Factors: A Cross-Sectional Study at a Brazilian Teaching Hospital(2022) SOUZA, Henrique D. de; FRANCISCO, Rossana P. V.; HASE, Eliane A.; DIORIO, Giselle R. M.; WAISSMAN, Adriana L.; PERES, Stela V.; ZUGAIB, Marcelo; GALLETTA, Marco A. K.Introduction: Bacteriuria during pregnancy is a frequent and important cause of morbidity and complications. Data on its occurrence in pregnant adolescents are still scarce. Methods: A cross-sectional study was conducted at a tertiary teaching hospital in Sao Paulo, Brazil. All adolescents (<= 18 years) who came for prenatal care between January 2010 and January 2016 were included. Sociodemographic characteristics, medical history, obstetric history, and the results of laboratory tests were selected. A urine sample was aseptically collected from each patient to undergo microscopic and culture analysis. Results: A total of 388 pregnant adolescents averaging 15.30 +/- 1.24 years of age were included. The frequency of bacteriuria in this group was 17.01% (66/388). The lack of sports practice (OR = 8.65; 95% CI, 1.09-68.39), the fact that pregnancy was desired (OR = 2.17; 95% CI, 1.08-4.34), and the use of hormonal methods of contraception (OR = 2.46; 95% CI, 1.04-5.84) turned out to be independent risk factors for bacteriuria. Protective factors were identified as late coitarche (OR = 0.75; 95% CI, 0.57-0.98) and a urine culture analysis at a later gestational age (OR = 0.94; 95% CI, 0.90-0.98). The most often isolated pathogens were Escherichia coli (49%) and Streptococcus agalactiae (18%). Conclusion: Bacteriuria among pregnant adolescents is a relatively common condition. The infection risk of the urinary tract was increased by physical inactivity and seemingly by the influence of behavioral and sexual factors. Such results can help to identify patients at risk, favoring the early diagnosis of urinary tract infections and optimizing prenatal care.
- DNA methylation mediates a randomized controlled trial home-visiting intervention during pregnancy and the Bayley infant's cognitive scores at 12 months of age(2022) EUCLYDES, Veronica L. V.; GASTALDI, Vinicius D.; FELTRIN, Arthur S.; HOFFMAN, Daniel J.; GOUVEIA, Gisele; COGO, Hugo; FELIPE-SILVA, Aloisio; VIEIRA, Rossana P.; MIGUEL, Euripedes C.; V, Guilherme Polanczyk; CHIESA, Anna; FRACOLLI, Lislaine; MATIJASEVICH, Alicia; FERRARO, Alexandre; ARGEU, Adriana; MASCHIETTO, Mariana; BRENTANI, Helena P.The crosstalk between maternal stress exposure and fetal development may be mediated by epigenetic mechanisms, including DNA methylation (DNAm). To address this matter, we collect 32 cord blood samples from low-income Brazilian pregnant adolescents participants of a pilot randomized clinical intervention study (ClinicalTrials.gov, Identifier: NCT02807818). We hypothesized that the association between the intervention and infant neurodevelopmental outcomes at 12 months of age would be mediated by DNAm. First, we searched genome methylation differences between cases and controls using different approaches, as well as differences in age acceleration (AA), represented by the difference of methylation age and birth age. According to an adjusted p-value <= 0.05 we identified 3090 differentially methylated positions- CpG sites (DMPs), 21 differentially methylated regions (DMRs) and one comethylated module weakly preserved between groups. The intervention group presented a smaller AA compared to the control group (p = 0.025). A logistic regression controlled by sex and with gestational age indicated a coefficient of -0.35 towards intervention group (p = 0.016) considering AA. A higher cognitive domain score from Bayley III scale was observed in the intervention group at 12 months of age. Then, we performed a potential causal mediation analysis selecting only DMPs highly associated with the cognitive domain (adj. R (2) > 0.4), DMRs and CpGs of hub genes from the weakly preserved comethylated module and epigenetic clock as raw values. DMPs in STXBP6, and PF4 DMR, mediated the association between the maternal intervention and the cognitive domain at 12 months of age. In conclusion, DNAm in different sites and regions mediated the association between intervention and cognitive outcome.
- Isolation and characterization of Toxoplasma gondii isolates from human congenital toxoplasmosis cases reveal a new virulent genotype in Sao Paulo, Brazil(2022) MEIRELES, Luciana Regina; BEZERRA, Elizama Carneiro Machado; ANDRADE, Joelma Queiroz; CASSIANO, Larissa Aparecida; PENA, Hilda Fatima Jesus; ALVES, Bruna Farias; FRANCISCO, Rossana Pulcineli Vieira; JR, Heitor Franco de AndradeToxoplasma gondii causes severe disease in congenitally infected fetuses. The severity of fetal infection is related to the gestational stage at the time of maternal infection, parasite burden, and genotypic characteristics. South America has a high incidence of congenital toxoplasmosis and has the highest genotypic diversity of the parasite. In Brazil, clinical toxoplasmosis in children is notorious, however there are very limited data regarding the strains recovered from congenital infections. In this study, T. gondii strains from two cases of severe congenital toxoplasmosis from the Sao Paulo metropolitan area were isolated (TgHumIMTBr2 and TgHumIMTBr3) and biologically and molecularly characterized using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and microsatellite analysis, revealing a new non-archetypal virulent genotype designated as #318. The other isolate, genotype #175, has already been described in domestic and wild animals in Brazil, but is now associated with acute toxoplasmosis in humans. These data reinforce the role of non-archetypal T. gondii genotypes in the severity of human congenital toxoplasmosis, highlighting the importance of studies focused on parasite isolation and genotyping for a better understanding of the virulence of isolates from human toxoplasmosis and contributing to the knowledge of the diversity of T. gondii in Brazil.
- Weight loss among pregnant women hospitalized because of hyperemesis gravidarum: Is there a lack of nutrition intervention?(2022) GALLETTA, Marco Aurelio Knippel; CARRIERI, Adriana; PERES, Stela Verzinhasse; DIAS, Maria Carolina Goncalves; FRANCISCO, Rossana Pulcineli VieiraBackground Nutrition therapy is a key component in the management of hyperemesis gravidarum (HG). The aim of this study was to describe sociodemographic, anthropometric, and nutrition aspects of pregnant women hospitalized because of HG and raise a discussion about the nutrition care provided. Materials and Methods This is a retrospective descriptive study that includes 26 pregnant women with confirmed diagnosis of HG who were hospitalized because of this condition in a tertiary hospital. Data of interest were collected from official medical records and analyzed to obtain measures of central tendency and dispersion, as well as frequencies. Results The studied individuals had a mean age of 25.7 years and a low level of education, and 65% of them were single mothers. They registered a low weight gain (2.8 kg) during pregnancy and in the course of their hospitalization, during which they lost an average of 1.7 kg, showing a decline in nutrition status during this period. Although the average intake of oral diet (OD) was 55% during hospital stay and only 5% of the studied population met caloric needs through OD, the prescription of complementary medical nutrition therapy (oral supplements, enteral or parenteral nutrition) was scarcely observed in this sample. Conclusion Despite the negative impact that HG can impose on the mother's nutrition status and the known benefits that complementary nutrition therapies can provide, few nutrition interventions have been carried out to improve this situation. That indicates an urgent need for implementation or reviewing of nutrition assistance protocols for HG patients.
- Sonographic evaluation of umbilical cord thickness in monochorionic diamniotic twin pregnancies(2022) NUNES, Clarissa Moraes; BIANCOLIN, Sckarlet Ernandes; MIYADAHIRA, Mariana Yumi; PERES, Stela Verzinhasse; CARVALHO, Mario Henrique Burlacchini de; FRANCISCO, Rossana Pulcineli Vieira; BRIZOT, Maria de LourdesObjective: To develop a nomogram of the thickness of the umbilical cord (UC) and its components in monochorionic diamniotic (MCDA) twin pregnancies. Methods: This prospective longitudinal study involved 47 MCDA twin pregnancies (94 fetuses) between 18 and 33 weeks of gestation. Ultrasound assessments of UC cross-sections and measurements of the umbilical cord area (UCA), the umbilical vein area (UVA), the umbilical artery area (UAA), and the Wharton jelly area (WJA) were made. The UC measurements were correlated with gestational ages. Reference values for the gestational ages of MCDA pregnancies were determined and compared with those of dichorionic twins and singletons. The cases which developed selective intrauterine growth restriction were contrasted with normal cases. Results: A positive correlation was found between all UC components and gestational age and fetal weight. The UCA of MCDA fetuses was significantly larger than that of DC fetuses (p < 0.001) at the expense of a larger WJA (p < 0.001) and similar to that of singleton pregnancies. The MCDA fetuses with an estimated fetal weight below the 10th percentile had a smaller UCA than fetuses with a normal estimated weight (p < 0.001). Conclusion: The MCDA twins exhibited a thicker UC than that of dichorionic twins.
- Plasmatic catecholamines after neuraxial labour analgesia: A randomised controlled trial comparing epidural versus combined spinal-epidural(2022) SANTOS, Shirley Andrade; FERNANDES, Hermann Dos Santos; NANI, Fernando Souza; BARTILOTTI, Andreza Gonzaga; FRANCISCO, Rossana Pulcineli Vieira; CARMONA, Maria Jose Carvalho; BLIACHERIENE, Fernando; VIEIRA, Joaquim EdsonBackground: Combined spinal-epidural technique (CSE) for labour analgesia has been associated with fetal bradycardia and uterine hypertonia when compared with epidural analgesia (EA), possibly due to a decrease in epinephrine levels following neuraxial anaesthesia. However, there are no recent studies comparing plasmatic catecholamines levels between those two techniques. This study aimed to compare CSE versus EA regarding pre- and post-analgesia catecholamines levels, uterine tone and fetal heart rate.Patients and methods: Randomised clinical trial with 47 labouring patients divided in two groups (CSE and EA). Primary outcome was plasmatic catecholamine measurements before and after neuraxial block. Secondary outcomes were fetal heart rate changes, uterine hypertonia, hypotension episodes, pain relief and fetal outcomes. Results: For CSE group, the median decrease of plasmatic epinephrine was 0 pg/mL [(-) 480-(+) 41] and for norepinephrine was -21 pg/mL [(-) 2507-(+) 94]. For EA group, the median decrease for epinephrine was 0 pg/mL [(-) 326-(+) 15] and for norepinephrine was -5 pg/mL [(-) 190-(+76)]. There were no differences between groups (p = 0.96 and p = 0.63 for epinephrine and norepinephrine, respectively). There were no differences for secondary outcomes.Conclusions: There was no evidence of a more significant decrease of catecholamines with CSE when compared with EA. Catecholamines decrease theory may not be valid for modern labour analgesia techniques. ⠃C 2022 Socie acute accent te acute accent franc , aise d'anesthe acute accent sie et de re acute accent animation (Sfar).
- Postpartum depressive symptoms of Brazilian women during the COVID-19 pandemic measured by the Edinburgh Postnatal Depression Scale(2022) GALLETTA, Marco Aurelio Knippel; OLIVEIRA, Ana Maria da Silva Sousa; ALBERTINI, Jessica Gorrao Lopes; BENUTE, Glaucia Guerra; PERES, Stela Verzinhasse; BRIZOT, Maria de Lourdes; FRANCISCO, Rossana Pulcineli VieiraBackground: The COVID-19 pandemic gave rise to concerns about its potential impact on the mental health of pregnant and postpartum women as the general postpartum depression rates increased. Methods: Three postpartum questionnaires (Edinburgh Postnatal Depression Scale - EPDS; Anxiety and Depression Scale - HAD; and a demographic questionnaire about isolation and information acquisition) were used to evaluate the mental health of women with and without COVID-19 and determine the factors associated with depressive symptoms (EPDS >= 12). Results: Data from 184 participants with a mean of 56 postpartum days were analyzed. The rate of symptoms compatible with postpartum depression (PPD) was 38.8%, with a 14.3% positive response to item 10 on the EPDS (suicidal ideation - SI). Listening to the news about COVID-19 averaged 4.45 hours a day. Factors related to PPD were concerns about lack of hospital beds (OR = 2.45), absence of a partner (OR = 2.70), and anxiety symptoms (OR = 10). Factors related to SI were anxiety symptoms (OR = 1.56) and friends as a source of information (OR = 5.60). Limitations: Considering the rapidly changing epidemiological conditions of this pandemic, this study may only be the photograph of an instant. Conclusions: Higher rates of PPD in the Brazilian population are related not only to anxiety but also to an inadequate family environment, kind of information acquisition and concerns about the lack of hospital beds.
