- 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.
- 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.
- Risk factors for oxygen requirement in hospitalized pregnant and postpartum women with COVID-19(2022) BAPTISTA, Fernanda Spadotto; PAGANOTI, Cristiane Freitas; GOMEZ, Ursula Trovato; PERES, Stela Verzinhasse; MALBOUISSON, Luiz Marcelo; BRIZOT, Maria de Lourdes; FRANCISCO, Rossana Pulcineli VieiraObjective: To identify risk factors for Oxygen (O-2) needs in pregnant and postpartum women with COVID-19. Methods: Prospective cohort involving pregnant women hospitalized with COVID-19 from April to October 2020. The oxygen need was analyzed regarding risk factors: demographic characteristics, clinical and laboratory parameters at hospital admission, and chest Computer Tomography (CT) findings. Poisson univariate analysis was used to estimate the Relative Risk (RR) and 95% Confidence Intervals. Results: 145 patients, 80 who used and 65 who did not use O-2, were included. Body mass index >= 30, smoking, and chronic hypertension increased the risk of O-2 need by 1.86 (95% CI 1.10-3.21), 1.57 (95% CI 1.16-2.12), and 1.46 (95% CI 1.09-1.95), respectively. Patients who were hospitalized for COVID-19 and for obstetric reasons had 8.24 (95% CI 2.8-24.29) and 3.44 (95% CI 1.05-11.31) times more use of O-2 than those admitted for childbirth and abortion. Respiratory rate >= 24 breaths/min and O-2 saturation < 95% presented RR for O-2 requirements of 2.55 (1.82-3.56) and 1.68 (95% CI 1.27-2.20), respectively. Ground Glass (GG) < 50% and with GG >= 50%, the risk of O-2 use were respectively 3.41-fold and 5.33-fold higher than in patients who haven't viral pneumonia on CT. The combination of C-reactive protein >= 21 mg/L, hemoglobin < 11.0 g/dL, and lymphopenia < 1500 mm(3) on hospital admission increased the risk of O-2 use by 4.97-times. Conclusions: In obstetric patients, clinical history, laboratory, clinical and radiological parameters at admission were identified as a risk for O-2 need, selecting the population with the greatest chance of worsening.
- Impact of SARS-CoV-2 on pregnancy and neonatal outcomes: An open prospective study of pregnant women in Brazil(2022) GOMEZ, Ursula Trovato; FRANCISCO, Rossana Pulcineli Vieira; BAPTISTA, Fernanda Spadotto; GIBELLI, Maria Augusta B. C.; IBIDI, Silvia Maria; CARVALHO, Werther Brunow de; PAGANOTI, Cristiane de Freitas; SABINO, Ester Cerdeira; SILVA, Lea Campos de Oliveira da; JAENISCH, Thomas; MAYAUD, Philippe; BRIZOT, Maria de LourdesObjectives: To determine the incidence and risk of adverse obstetric and neonatal outcomes according to SARSCoV-2 infection severity in pregnant women. Method: Open prospective study of pregnant women tested for SARS-CoV-2 by serological and molecular assays during pregnancy or delivery in two hospitals in Sao Paulo, Brazil from April 12, 2020, to February 28, 2021. Five groups were considered for analysis: C0, negative COVID-19 results and no COVID-19 symptoms; C1, positive COVID-19 results, and no symptoms; C2, positive COVID-19 results with mild symptoms; C3, positive COVID-19 results with moderate symptoms; and C4, positive COVID-19 results with severe symptoms. The association between obstetric and neonatal outcomes and COVID-19 severity was determined using multivariate analysis. Results: 734 eligible pregnant women were enrolled as follows: C0 (n = 357), C1 (n = 127), C2 (n = 174), C3 (n = 37), and C4 (n = 39). The following pregnancy and neonatal outcomes were associated with severe COVID19: oligohydramnios (adjusted Odds Ratio [aOR] = 6.18; 95% CI 1.87-20.39), fetal distress (aOR = 4.01; 95% Confidence Interval [CI] 1.84-8.75), preterm birth (aOR = 5.51; 95% CI 1.47-20.61), longer hospital stay (aOR = 1.66; 95% CI 1.36-2.02), and admission to the neonatal intensive care unit (aOR = 19.36; 95% CI, 5.8663.99). All maternal (n = 6, 15.4%, p < 0.001) and neonatal (n = 5, 12.5%, p < 0.001) deaths and most fetal deaths (n = 4, 9.8%, p < 0.001) occurred in C4 group. Moderate COVID-19 was associated with oligohydramnios (aOR = 6.23; 95% CI 1.93-20.13) , preterm birth (aOR = 3.60; 95% CI 1.45-9.27). Mild COVID-19 was asso-ciated with oligohydramnios (aOR = 3.77; 95% CI 1.56-9.07). Conclusion: Adverse pregnancy and neonatal outcomes were associated with maternal symptomatic COVID-19 sta-tus , risk increased with disease severity.

- Clinical characteristics and evolution of 71 neonates born to mothers with COVID-19 at a tertiary center in Brazil(2022) DUARTE, Bruna de Paula; KREBS, Vera Lucia Jornada; CALIL, Valdenise Martins Laurindo Tuma; CARVALHO, Werther Brunow de; GIBELLI, Maria Augusta Bento Cicaroni; FRANCISCO, Rossana Pulcineli VieiraIntroduction: Limited data are available on pregnant women with COVID-19 and their neonates.Objective: This study aimed to describe clinical characteristics and evolution from birth to discharge of a retrospec-tive cohort of 71 neonates, with one set of twins, born to women with COVID-19 diagnosed at the end of preg-nancy. The authors included all newborns admitted into a neonatal unit of a tertiary hospital in Brazil, between March 2020 and March 2021, whose unvaccinated mothers had COVID-19 symptoms and RT-PCR (Real-Time Polymerase Chain Reaction) for SARS-CoV-2 positive within fourteen days prior to delivery. Newborns to mothers with COVID-19 symptoms and negative tests for SARS-CoV-2 were excluded. Results: The main route of birth delivery was cesarean, corresponding to 60 pregnant women (84.5%). The fore-most indications for cesarean were pregnant with critical disease (24.6%) and acute fetal distress (20.3%). The mean birth weight was 2452 g (865-3870 g) and the mean gestational age was 345/7 weeks (25-40 weeks). There were 45 premature newborns (63.3%), of which 21 newborns (29.5%) were less than 32 weeks of gestational age. RT-PCR for SARS-CoV-2 on oropharyngeal swabs was positive in 2 newborns (2.8%) and negative in the other 69 newborns (97.2%). Most newborns (51.4%) needed respiratory support. Therapeutic interventions dur-ing hospitalization were inotropic drugs (9.9%), antibiotics (22.8%), parenteral nutrition (26.8%), and photother-apy (46.5%).Conclusion: Maternal COVID-19 diagnosticated close to delivery has an impact on the first days of neonatal life.
