Purpose: the repetitive use of antenatal corticosteroid therapy for acceleration of fetal lung maturation has been common in cases at risk of preterm delivery. We studied the corticosterone levels at term and the morphologic aspects in the maternal and fetal adrenal glands submitted to the effect of betamethasone in the second half of rat pregnancy in order to verify its consequences. Methods: thirty female pregnant rats were divided into three groups of ten animals each. Group I received betamethasone on the 11th, 12th, 18th and 19th day of pregnancy. Group II received distilled water on the same days (control group). Group III did not receive any drug (stress control group). All rats were sacrificed on the 20th day of pregnancy when plasma corticosterone levels of dams were assessed and the maternal and fetal adrenal glands were studied by light microscopy. Results: plasma corticosterone level of dams was lower in the group treated with betamethasone (4.8 mg/dL) when compared with the control groups (17.7 and 26.8 mg/dL). The light microscopy study revealed cytoplasmatic vacuolation in the fasciculate zone in the maternal and fetal adrenal glands, which indicates adrenal suppression. Conclusions: the antenatal repetitive and prolonged use of corticosteroids in pregnant rats for acceleration of lung fetal maturation causes maternal and fetal adrenal suppression.

Purpose: evaluation of perinatal outcome of brain-sparing effect detected by color Doppler. Methods: brain-sparing effect was detected in 32 fetuses at the Ultrasound Service of the Center for Integral Attention to Women’s Health at Campinas State University (UNICAMP). The diagnosis of brain-sparing effect was made when the ratio between middle cerebral artery and umbilical artery pulsatility indexes was below one (IPACM/IPAU <1). The measurement was obtained with color Doppler equipment Toshiba SSH-140A. Results: admission to neonatal intensive care unit (ICU) was necessary in 26 fetuses (89.6%). The number of days in ICU varied from 1 to 83 days, with a mean of 22 days. Fetal mortality rate was 3 in 32 (9.4%) and perinatal mortality was 9 in 29 (31%). Considering the gestational age by the Capurro method, the incidence of birth below 36 weeks was 21 in 32 (65.6%). Intrauterine growth restriction occurred in 71.8% of the cases and hypoglycemia in 44.8%. Conclusions: brain-sparing effect is a condition in which the fetus is at serious risk of adverse perinatal outcome and Doppler studies might be helpful in the obstetric management.

Abstract

Objective

To compare the effectiveness and safety of non-mRNA versus mRNA COVID-19 vaccines on pregnant women and their newborns in a systematic review with meta-analysis.

Data sources

We searched PubMed, Embase, and Cochrane Central in May 2023.

Study selection

The search strategy yielded 4451 results, 16 studies were fully reviewed. We selected case-control studies analysing non-mRNA versus mRNA vaccines. Data collection and analysis: we assessed the risk of bias using the Cochrane Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool. Standardised mean differences were pooled using random-effect models.

Data synthesis

We identified 8 prospective and retrospective studies with a total of 32,153 patients. Non-mRNA vaccines were associated with a higher incidence of fever (OR 2.67; 95% CI 2.08-3.43; p<0.001), and a lower incidence of fetal or neonatal death (OR 0.16; 95% CI 0.08-0.33; p<0.001). In subgroup analyses, the Jansen vaccine (Ad26.COV2.S) was found to have a higher rate of premature labor/delivery (OR 4.48; 95% CI 1.45-13.83; p=0.009) and missed/spontaneous abortion (OR 1.90; 95% CI 1.09-3.30; p=0.02), as compared with the Pfizer (BNT162b2) vaccine.

Conclusion

non-mRNA vaccines are associated with a lower incidence of fetal or neonatal death among pregnant women who receive a Covid19 vaccine, although at an increased rate of pyrexia compared with mRNA vaccines. Other studies are required for better assessment.

Abstract

Objective

Compare the number of puerperal women submitted to blood transfusion before and after the implementation of a care protocol for postpartum hemorrhage (PPH) with multidisciplinary team training.

Methods

Cross-sectional study in a university hospital, analyzing births from 2015 to 2019, compared the use of blood products before and after the adoption of a PPH protocol with multidisciplinary training.

Results

Between 2015 and 2019, there were 17,731 births, with 299 (1.7%) postpartum women receiving blood products and 278 postpartum women were considered for this analysis, 128 (0.7%) at Time 1 and 150 (0.8%) at Time 2. After the multiprofessional team training (T2), there was a difference in the complete use of the PPH protocol (use of oxytocin, misoprostol and tranexamic acid) (T1 = 5.1% x T2 = 49.5%, p≤0.0001). An individual categorized analysis revealed that, in the T2 period, there was lower use of blood component units per patient compared to T1 (Mann-Whitney, p=0.006). It should be noted that at T1 and T2, 54% and 24% respectively received two units of blood products. It is important to highlight that after the multidisciplinary team training for the PPH protocol, the goal of zero maternal death due to hemorrhage was reached.

Conclusion

The adoption of a specific protocol for PPH, combined with the training of a multidisciplinary team, had an impact on the ability to identify women at high risk of hemorrhage, resulting in a decrease in the use of blood components.

Abstract

Objective

To evaluate early complications in prepectoral breast reconstruction.

Methods

A retrospective cohort study including 180 consecutive cases of nipple-sparing mastectomy, comparing immediate breast reconstruction with subpectoral to prepectoral mammary implants in 2012-2022. Clinical and demographic characteristics and complications in the first three months following surgery were compared between the two techniques.

Results

The prepectoral technique was used in 22 cases (12.2%) and the subpectoral in 158 (87.8%). Median age was higher in the prepectoral group (47 versus 43.8 years; p=0.038), as was body mass index (25.1 versus 23.8; p=0.002) and implant volume (447.5 versus 409 cc; p=0.001). The prepectoral technique was more associated with an inframammary fold (IMF) incision (19 cases, 86.4% versus 85, 53.8%) than with periareolar incisions (3 cases, 13.6% versus 73, 46.2%); (p=0.004). All cases in the prepectoral group underwent direct-to-implant reconstruction compared to 54 cases (34.2%) in the subpectoral group. Thirty-eight complications were recorded: 36 (22.8%) in the subpectoral group and 2 (9.1%) in the prepectoral group (p=0.24). Necrosis of the nipple-areola complex/skin flap occurred in 27 patients (17.1%) in the subpectoral group (prepectoral group: no cases; p=0.04). The groups were comparable regarding dehiscence, seroma, infection, and hematoma. Reconstruction failed in one case per group (p=0.230). In the multivariate analysis, IMF incision was associated with the prepectoral group (aOR: 34.72; 95%CI: 2.84-424.63).

Conclusion

The incidence of early complications was comparable between the two techniques and compatible with previous reports. The clinical and demographic characteristics differed between the techniques. Randomized clinical trials are required.

Abstract

Objective

To identify the opinion of coordinators and members about the essential characteristics and to understand the research networks characteristics, to facilitate their implementation, sustainability and effectiveness so it can be replicated in low and middle-income countries.

Methods

A qualitative study using a semi-structured interview technique was conducted. We selected potential members, managers and participants of networks from publications identified in PubMed. After checking the FIGO congress program, we identified authors who were assigned as speakers at the event. An invitation was sent and interviews were scheduled.

Results

In total, eleven interviews were performed. Coordinators and members of networks have the same goal when they decide to participate in a network. In general, they cited that these individuals had to be committed, responsible and enthusiastic people. The network should be composed also of postgraduate students. A network should allow multi-leadership, co-responsibility, autonomy and empowerment of its members. Effective communication was mentioned as an important pillar for network maintenance. Another motivation is being an author or coauthor in publications. One way to maintain a network running is social or governmental commitment, after resources expire, studies continue.

Conclusion

Networks are different due to the social context where they are inserted, however, some characteristics are common to all of them, such as having engaged leaders. For an effective and sustainable network, commitment and motivation in a leader and members are more in need than financial resources. Ideally, to ensure the operation of the network, the institution where the leader is linked should support this network.

Abstract

Objective

This study aims to evaluate the clinical outcomes of surgical management for placenta accreta spectrum in a Latin American reference hospital specializing in this condition. The evaluation involves a comparison between surgeries performed on an emergent and scheduled basis.

Methods

A retrospective cohort study was conducted on patients with placenta accreta spectrum who underwent surgery between January 2011 and November 2021 at a hospital in Colombia, using data from the institutional PAS registry. The study included patients with intraoperative and/or histological confirmation of PAS, regardless of prenatal suspicion. Clinical outcomes were compared between patients who had emergent surgeries and those who had scheduled surgeries. Descriptive analysis involved summary measures and the Shapiro-Wilk test for quantitative variables, with comparisons made using Pearson’s Chi-squared test and the Wilcoxon rank sum test, applying a significance level of 5%.

Results

A total of 113 patients were included, 84 (74.3%) of them underwent scheduled surgery, and 29 (25.6%) underwent emergency surgery. The emergency surgery group required more transfusions (72.4% vs 48.8%, p=0.047). Patients with intraoperative diagnosis of placenta accreta spectrum (21 women, 19.5%) had a greater volume of blood loss than patients taken into surgery with known presence of placenta accreta spectrum (3500 ml, IQR 1700 – 4000 vs 1700 ml, IQR 1195-2135. p <0.001).

Conclusion

Patients with placenta accreta spectrum undergoing emergency surgery require transfusions more frequently than those undergoing scheduled surgery

Abstract

Objective

26% of all pregnancies end in miscarriage, and up to 10% of clinically diagnosed pregnancies, and recurrent pregnancy loss is 5% among couples of childbearing ages. Although there are several known causes of pregnancy loss in the first half, including recurrent pregnancy loss, including parental chromosomal abnormalities, uterine malformations, endocrinological disorders, and immunological abnormalities, about half of the cases of pregnancy loss in its first half remain unexplained.

Methods

The review includes observational controlled studies (case-control or cohort, longitudinal studies, reviews, meta-analyses), which include the study of biochemical factors for predicting pregnancy losses in the first half, in singlet pregnancy. The Newcastle-Ottawa Scale (NOS) was used to assess the research quality.

Results

Finally, 27 studies were included in the review, which has 134904 examined patients. The results of the review include estimates of β-human chorionic gonadotropin, progesterone, pregnancy-associated protein – A, angiogenic vascular factors, estradiol, α-fetoprotein, homocysteine and CA-125 as a predictors or markers of the first half pregnancy losses.

Conclusion

It may be concluded that to date, research data indicate the unavailability of any reliable biochemical marker for predicting pregnancy losses in its first half and require either a combination of them or comparison with clinical evidence. A fairly new model shall be considered for the assessment of α-fetoprotein in vaginal blood, which may have great prospects in predicting spontaneous miscarriages.

Abstract

Objective

To evaluate the association between the dietary patterns (DPs) of pregnant women with GDM (gestational diabetes mellitus) and the birth weight (BW) of the infants.

Methods

Cross-sectional study with 187 adult pregnant women with GDM attended at a maternity in Rio de Janeiro from 2011 to 2014. Dietary intake was assessed in the third trimester using a semiquantitative food frequency questionnaire (FFQ). The outcomes were BW and weight adequacy for gestational age (GA). Reduced Rank Regression (RRR) was used to explain the following response variables: density of carbohydrates, fibres, and saturated fatty acids. Statistical analyzes included multinomial logistic regression models.

Results

The mean BW was 3261.9 (± 424.5) g. Three DPs were identified, with DP 3 (high consumption of refined carbohydrates, fast foods/snacks, whole milk, sugars/sweets, and soft drinks and low consumption of beans, vegetables, and low-fat milk and derivatives) being the main pattern, explaining 48.37% of the response variables. In the multinomial logistic regression analysis no statistically significant association was found between the tertiles of DPs and BW or the adequacy of weight for GA, even after adjustments of confounding covariates.

Conclusion

No significant associations were found between maternal DPs in the third trimester of pregnancy and infant BW or adequacy of weight for GA.

Abstract

Objective:

Preterm birth remains a significant contributor to neonatal morbidity and mortality. The use of cervical pessaries as an intervention for preventing preterm delivery in women with a short cervix has been a subject of interest. We evaluated the effectiveness of cervical pessary compared to standard care in preventing preterm delivery in women with a short cervix.

Data source:

Databases were systematically searched in PubMed, Cochrane, and Embase databases in December 2023.

Study selection:

Randomized clinical trials with the outcomes of interest were included.

Data collect:

We computed risk ratios for binary endpoints, with 95% confidence intervals. Heterogeneity was assessed using I2 statistics. Data were analyzed using R software (version 4.3.0). The primary outcomes of interest were preterm delivery before 37 weeks, and preterm delivery before 34 weeks.

Data synthesis:

Seventeen studies with 5,704 patients were included. The use of cervical pessary was associated with a decreased risk of preterm delivery before 37 (RR 0.88; 95% CI 0.81-0.96) and 34 weeks (RR 0.79; 95% CI 0.63-0.99) of gestation in twin pregnancies as compared to standard care without progesterone. There were no significant differences in preterm delivery in singleton pregnancy, neonatal outcomes, preterm premature rupture of the membranes or chorioamnionitis.

Conclusion:

The use of cervical pessary was associated with a significant reduction in preterm delivery at 34 and 37 weeks of gestation in twin pregnancies among patients with a short cervix compared to no treatment. No significant difference was found in singleton pregnancies or maternal outcomes.

Abstract

Objective:

To evaluate the continuation rate, satisfaction, and reasons for discontinuation of depot medroxyprogesterone acetate (DMPA) in adolescents treated in a mental health service.

Methods:

Prospective cohort study conducted in a reference unit for the care of adolescents with mental disorders (MDs) and intellectual disabilities (IDs). All patients received a gynecological consultation and an educational group on contraceptive methods. Sociodemographic data on age, education and gynecological data (menarche, coitarche, regularity of menstrual cycles and presence of symptoms) were collected. Follow-up was quarterly for 12 months, during which symptoms, desire to continue, and satisfaction with the use of the quarterly injectable were assessed.

Results:

Eight hundred and sixty-two sexually active adolescents were supported, 532 adolescents chose to use the quarterly injectable, and 69 of these agreed to participate in the study. The mean age of users was 15.5 years (SD=0.91). After 12 months of follow-up, 34 (49.3%) of the 69 adolescents continued to use the method and 36 (52.3%) were satisfied. Among the 33 (47.8%) who discontinued use, the most common reasons were irregular bleeding and weight gain.

Conclusions:

Adolescents with intellectual disabilities and/or other mental disorders showed a significant rate of continuation and satisfaction with the use of the depot medroxyprogesterone acetate at 12 months, and the most common reasons for discontinuation were irregular uterine bleeding and weight gain.

Abstract

Objective:

To describe women’s experience of pregnancy during the COVID-19 pandemic.

Methods:

A qualitative study conducted in a private maternity hospital, from May, 2020 to November, 2021, with women aged ≥ 18 years, gestational age ≥ 36 weeks at birth and ≥ 24 hours post-partum. Data collected through semi-structured interviews, recorded, transcribed, and analyzed adopting Krippendorff’s Content Analysis as theoretical-methodological framework.

Results:

Four main themes emerged: Fear, Taking care and celebrating pregnancy: adjusting to the new reality, Harms of Isolation, and Benefits of Isolation. The fear of contamination and its impact on the health of mother and child resulted in the adoption of severe social isolation, including from those considered sources of support by the expecting mother. Overwhelmed, some of the participants reported loneliness and psychic suffering. The opportunity to focus on the pregnancy, the preparations for the arrival of the child, and the family made isolation a beneficial and positive period for other women.

Conclusion:

The experience of pregnancy in the Pandemic was an event outside of the ordinary and common. The expecting mother faced her worst fears on a daily basis and attended prenatal care, in order to ensure her child would be born healthy. The celebration of the baby’s life, amid so many deaths, had to be adjusted to the virtual environment. It was a tense, solitary, and ambiguous period, which demanded a lot from the mental health of some participants, but to others, brought advantages that would not have been possible in different times.

Abstract

Objective:

To investigate the relationship between prematurity and cesarean section rate in Brazil during the beginning of COVID-19 pandemic.

Methods:

Utilizing the Robson Classification, this study analyzed data from the Brazilian Ministry of Health’s Live Births Panel, comparing CSR) and group 10 (preterm deliveries) between 2019 (pre-pandemic) and 2021 (pandemic) in each of Brazilian states and the overall country. The prematurity and CSR were compared using prevalence ratio and confidence interval, and p-value was obtained. The variation of prematurity and CSR were compared through the coefficient of determination (R2).

Results:

A total of 5,522,910 deliveries were evaluated during the period. The CSR increased from 56.34% to 57.05% (p<0.01), and the frequency of preterm deliveries rose from 8.99% to 9.13% (p<0.01). The CSR increased in 23 States and decreased in 4 States, while the prematurity rate increased in 16 States and decreased in 10 States. A positive relationship between the increase of CSR and prematurity was observed during COVID-19, with an R2 value of 0.3121, suggesting a moderate association between these two variables.

Conclusion:

Between 2019 (pre-COVID-19 pandemic) and 2021 (the first full year of the COVID-19 pandemic), there was an increase in prematurity and CSR in Brazil. These increases were observed in most Brazilian states and may be correlated. However, it is impossible to establish a cause-effect relationship given the design of this study.

Abstract

Objective:

To determine the validity of the angle of progression (AoP) in predicting delivery mode among women in the second stage of labor.

Designs:

This prospective cohort study was conducted at the Obstetrics and Gynecology unit (OBGYN) of two hospitals in Vietnam. Transperineal ultrasound was performed for each woman to measure the progression angle in the second phase of labor.

Participants:

A total of 725 women with singleton pregnancies with cephalic presentation at term

Methods:

Transperineal ultrasound was used to measure the angle of progression in the second labor phase and to identify the delivery method.

Results:

The rate of vaginal birth in women with an AoP ≥ 120° on transperineal ultrasound was 70.2%. The optimal cutoff point of AOP ≥122° with sensitivity and specificity for vaginal birth were 87.8% and 80.7%, respectively the area under the ROC curve of 0.887 (p<0.0001). The study's sample size was restricted owing to deficiencies in resources and time.

Conclusion:

The likelihood of achieving spontaneous vaginal delivery can be predicted by the angle of progression measured with transperineal intrapartum ultrasonography during the second stage of labor in women.

Abstract

Objective:

This study aimed to verify the relation between gastrin-releasing peptide receptor (GRPR), oncogenic Human Papillomavirus (HPV) and cervical lesions severity.

Methods:

GRPR mRNA levels were evaluated in cervical cancer-derived cell lines and in primary keratinocytes expressing HPV16 oncogenes by RT-PCR. GRPR protein expression was assessed by immunohistochemistry in organotypic cell cultures derived from keratinocytes transduced with HPV16 oncogenes and in 208 cervical samples, including 59 non-neoplastic tissue, 28 cervical intraepithelial neoplasia grade 3 (CIN3), 44 squamous cell carcinomas (SCC) and 77 adenocarcinomas (ADC). Generic primers (GP5+/GP6+) were used to identify HPV infection in tissue samples. Experiments involving cell lines were analyzed through non-parametric tests (Kruskal Wallis), and Fisher’s Exact Test for human tissues samples. All statistical tests were considered significant at p <0.05. Immunohistochemical evaluation was conducted independently and blindly by two observers (AD- LO). Any discordant findings were resolved through discussion to reach a consensus score.

Results:

GRPR mRNA levels were not increased in cells expressing HPV16 or HPV18 oncogenes. However, at the protein level, GRPR was upregulated in organotypic cell cultures containing HPV oncogenes. Besides, it was identified an association between GRPR expression and cervical lesion severity (p < 0.0001). The detection rate of high-risk HPV DNA was directly correlated with cervical disease. Nonetheless, HPV infection was not directly associated with GRPR in cervical samples.

Conclusion:

GRPR expression is highly predictive of cervical lesion severity, irrespective of HPV infection and might contribute to improving patient’s therapeutic management as well as being used a marker of disease progression.

Abstract

Objective:

This study aimed to investigate the effect of low-level laser therapy (LLLT) on nipple trauma and pain during breastfeeding through a systematic review with a meta-analysis of selected studies.

Source of the data:

A thorough search was conducted on March 22, 2022, using the databases PubMed, SciELO, LILACS, PEDro, CINAHL, EMBASE, ScienceDirect, Scopus, Google Scholar, MEDLINE, the Cochrane Library, Clinical Trials, Web of Science, TRIP, DARE, and ProQuest. The search terms included various combinations of low-level laser therapy, nipple pain, nipple trauma, and breastfeeding.

Studies selection:

Out of 107 articles identified, only three controlled and randomized clinical trials was included. The extracted data encompassed breast and trauma characteristics, treatment types, outcomes (pain and healing process), evaluation tools, LLLT usage, laser brand, and parameters.

Data collection:

Data extraction was performed using RAYYAN for systematic reviews. The risk of bias in the studies was evaluated.

Data synthesis:

Pain was measured using the visual analog scale (VAS). The included studies did not use validated tools for assessing physical conditions. All studies employed LLLT with a 660-nm wavelength, though there were variations in equipment power, energy dose, and application methods. The meta-analysis revealed an average difference of −0.60 points (95% CI: −1.52 to 0.31) in the VAS pain scores between the LLLT and control groups. No heterogeneity was observed among the studies (I2=0%), indicating no significant difference in pain relief between LLLT (red light) and control groups.

Conclusion:

LLLT may offer a promising option for managing breastfeeding-related complications, though further research is required.

Abstract

Statins are the most widely used pharmacological class for treating hyperlipidemia, although they are contraindicated during pregnancy. This study aims to demonstrate the clinical effects of statins in pregnant women through an interactive review. Fifteen original articles were selected, in English or Portuguese, within of five years. Statins have not been associated with the development of fetal malformations and their use may be useful in preventing unfavorable cardiovascular outcomes, with the potential to reduce oxidative stress and angiogenic dysfunction. However, the use of statins to prevent pre-eclampsia in humans has not been properly clarified and further studies are needed. Pravastatin is considered safer than statins for use during pregnancy.
