    Abstract

    Objective

    The present study assesses the implementation and the impact after 2 years of a school-based human papillomavirus (HPV) vaccination program in a Brazilian city.

    Methods

    A prospective study assessing the implementation of the program, offering quadrivalent HPV vaccine in two annual doses to girls and boys aged from 9 to 10 years old. The program was started in the city of Indaiatuba, state of São Paulo, Brazil, in 2018, and had authorization from the National Immunization Program. The number of HPV vaccine first doses applied and the coverage in 2018 was calculated and compared to the year 2017. There were described events that have influenced the results.

    Results

    The program invited 4,878 children through schools (87.1% of the target population), and 7.5% refused vaccination. Several concurrent events required or competed for health professionals of the vaccination teams. The coverage of the first dose (between 9 and 10 years old) was 16.1% in 2017 and increased to 50.5% in 2018 (p < 0.0001). The first dose in all ages increased 78% in 2018 compared with 2017 (6,636/3,733). Competing demands over the program continued in 2019, and the first dose coverage dropped (26.9%). For 2020, a municipal law instituted school-based vaccination and the creation of dedicated teams for vaccination, and these strategies are waiting to be tested.

    Conclusion

    School-based annual HPV vaccination in children between 9 and 10 years old was feasible and increased vaccination coverage, regardless of gender, although the program was vulnerable to competing events.

    Abstract

    Objective

    To study maternal anxiety in pregnant women without comorbidities in the context of the COVID-19 outbreak in Brazil and to study maternal knowledge and concerns about the pandemic.

    Methods

    This is a secondary analysis from a national multicenter cross-sectional study performed in 10 cities, from June to August, 2020, in Brazil. Interviewed postpartum women, without medical or obstetrical comorbidities, were included in the present subanalysis. A structured questionnaire and the Beck Anxiety Inventory (BAI) were applied.

    Results

    Out of the 1,662 women, 763 (45.9%) met the criteria for the current analysis and 16.1% presented with moderate and 11.5% with severe maternal anxiety. Moderate or severe maternal anxiety was associated with high school education (odds ratio [OR]:1.58; 95% confidence interval [CI]:1.04–2.40). The protective factor was cohabiting with a partner (OR: 0.46; 95%CI: 0.29–0.73). There was a positive correlation between the total BAI score and receiving information about care in the pandemic (rpartial 0.15; p < 0.001); concern about vertical transmission of COVID-19 (rpartial 0.10; p = 0.01); receiving information about breastfeeding (rpartial 0.08; p = 0.03); concerns about prenatal care (rpartial 0.10; p = 0.01), and concerns about the baby contracting COVID-19 (rpartial 0.11; p = 0.004). The correlation was negative in the following aspects: self-confidence in protecting from COVID-19 (rpartial 0.08; p = 0.04), having learned (rpartial 0.09; p = 0.01) and self-confidence in breastfeeding (rpartial 0.22; p < 0.001) in the context of the pandemic.

    Conclusion

    The anxiety of pregnant women without medical or obstetrical comorbidities was associated to high school educational level and not living with a partner during the COVID-19 pandemic. Self-confidence in protecting against COVID-19 and knowledge about breastfeeding care during the pandemic reduced maternal anxiety.

    Abstract

    Objective

    To evaluate the knowledge, attitudes, and behaviors regarding complementary and alternative medicine methods of patients who were admitted to gynecology outpatient clinics.

    Methods

    In the present survey, a questionnaire on complementary and alternative medicine practices was applied on 1,000 women (ages between 18 and 83 years old) who were admitted to the gynecology outpatient clinic of a tertiarymaternity hospital. Demographic features and knowledge, attitudes, and behaviors about these methods were inquired in face-to-face interviews.

    Results

    While 80.7% of the total participants thought that complementary and alternative medicine was beneficial, only 37.5% of them had used these methods previously. The rate of prior knowledge on this subject was of 59.7% and the source of information was physicians for 8.5% of the patients. However, 72.4% of all participants wanted to obtain information on these methods and 93.7% wanted to be informed by physicians. In the decision tree model, having knowledge about complementary and alternative medicine was the most effective factor determining its use (p<0.001). Phytotherapy was found to be the most used method, with 91.4%. The most preferred plant was onion (18.9%), and the most common reasons for herbal use were stress (15.4%) and fatigue (15.2%).

    Conclusion

    More than one-third of the patients who applied to the gynecology outpatient clinics used one of the complementary and alternativemedicine methods at least once. As gynecologists and obstetricians, we need to be more knowledgeable about these methods to provide correct guidance to our patients for accessing accurate and effective information.

    Abstract

    Objective

    The aim of the present study was to examine the relation between the PON1 polymorphisms and recurrent pregnancy loss (RPL).

    Methods

    In a cross-sectional study, blood samples were collected from 100 females. DNA was extracted and PON1 genotypes were determined by polymerase chain reaction (PCR) amplification.

    Results

    Regarding PON1 L55M, the mutated allele (M) frequency was found in 70.5% in RPL and in 53.5% in controls; theMallele was significantly associated with an increased risk of RPL (adjusted odds ratio [ORadj]=2.07; 95% confidence interval [CI]; p<0.001). However, regarding PON1 Q192R, the R mutated allele frequency was found in 28.5% in RPL and in 33% in controls. The R allele did not show any risk for RPL (ORadj 0.81; 95%CI; p=0.329).

    Conclusion

    The present study suggests that there is an effect of genetic polymorphism on RPL and provides additional evidence that combines with the growing information about the ways in which certain PON1 genotypes can affect the development of the fetus in the uterus.

    Abstract

    Objective

    To investigate the characteristics of women who had preterm birth (PTB) and related outcomes according to ethnicity.

    Methods

    A secondary analysis of a multicenter cross-sectional study conducted in Brazil. Women who had PTB were classified by self-report as white and non-white. Clinical, pregnancy, and maternal data were collected through postpartum interviews and reviews of medical charts. The sociodemographic, obstetric and clinical characteristics of the women, as well as the mode of delivery and the neonatal outcomes among different ethnic groups were compared through a bivariate analysis.

    Results

    Of the 4,150 women who had PTB, 2,317 (55.8%) were non-white, who were more likely: to be younger than 19 years of age (prevalence ratio [PR]: 1.05; 95% confidence interval [95%CI]: 1.01-1.09); to be without a partner; to live on low income; to have lower levels of schooling; to have ≥ 2 children; to perform strenuous work; to be fromthe Northeastern region of Brazil rather than the from Southern region; to have a history of ≥ 3 deliveries; to have an interpregnancy interval<12 months; to have pregnancy complications such as abortion, PTB, preterm premature rupture of membranes (pPROM), and low birth weight; to initiate antenatal care (ANC) visits in the second or third trimesters; to have have an inadequate number of ANC visits; to be under continuous overexertion; to smoke in the first and second or third trimesters; and to have anemia and gestational hypertension. The maternal and neonatal outcomes did not differ between the groups, except for the higher rate of low birth weight (73.7% versus 69.0%) in infants born to non-white women, and the higher rate of seizures (4.05% versus 6.29%) in infants born to white women.

    Conclusion

    Unfavorable conditions weremore common in non-whites than inwhites. Proper policies are required to decrease inequalities, especially in the context of prematurity, when women and their neonates have specific needs.

    DOI 10.1055/s-0041-1739461

    Views249

    Abstract

    Objective

    To compare maternal and perinatal risk factors associated with complete uterine rupture and uterine dehiscence.

    Methods

    Cross-sectional study of patients with uterine rupture/dehiscence from January 1998 to December 2017 (30 years) admitted at the Labor and Delivery Unit of a tertiary teaching hospital in Canada.

    Results

    There were 174 (0.1%) cases of uterine disruption (29 ruptures and 145 cases of dehiscence) out of 169,356 deliveries. There were associations between dehiscence and multiparity (odds ratio [OR]: 3.2; p=0.02), elevated maternal body mass index (BMI; OR: 3.4; p=0.02), attempt of vaginal birth after a cesarian section (OR: 2.9; p=0.05) and 5-minute low Apgar score (OR: 5.9; p<0.001). Uterine rupture was associated with preterm deliveries (36.5 ± 4.9 versus 38.2 ± 2.9; p=0.006), postpartum hemorrhage (OR: 13.9; p<0.001), hysterectomy (OR: 23.0; p=0.002), and stillbirth (OR: 8.2; p<0.001). There were no associations between uterine rupture and maternal age, gestational age, onset of labor, spontaneous or artificial rupture of membranes, use of oxytocin, type of uterine incision, and birthweight.

    Conclusion

    This large cohort demonstrated that there are different risk factors associated with either uterine rupture or dehiscence. Uterine rupture still represents a great threat to fetal-maternal health and, differently from the common belief, uterine dehiscence can also compromise perinatal outcomes.

    Abstract

    Objective

    The psychosocial burden of infertility among couples can be one of the most important reasons for women’s emotional disturbance. The goal of the present study was to investigate the effect of counseling on different emotional aspects of infertile women.

    Methods

    The present randomized clinical trial was performed on 60 couples with primary infertility who were referred for treatment for the first time and did not receive psychiatric or psychological treatment. Samples were allocated to an intervention group (30 couples) and a control group (30 couples) by simple randomization. The intervention group received infertility counseling for 6 45-minute sessions twice a week, and the control group received routine care. The Screening on Distress in Fertility Treatment (SCREENIVF) questionnaire was completed before and after the intervention. Samples were collected from November to December 2016 for 3 months. For the data analysis, we used the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, United States) software, version 19.0, and the paired t-test, the independent t-test, the Mann-Whitney test, the Wilcoxon test, and the Chi-squared test.

    Results

    The mean age of the participants was 33.39±5.67 years. All studied couples had primary infertility and no children. The mean duration of the couples’ infertilitywas 3 years. There was a significant difference regarding depression (1.55±1.92; p<0.0001), social support (15.73±3.41; p<0.0001), and cognitions regarding domains of fertility problems (26.48±3.05; p=0.001) between the 2 groups after the intervention, but there was no significant difference regarding anxiety (25.03±3.09; p=0.35).

    Conclusion

    The findings showed that infertility counseling did not affect the total score of infertile women’ emotional status, but improved the domains of it except, anxiety.
