Systematic Review and Meta-Analysis of Congenital Toxoplasmosis Diagnosis: Advances and Challenges.

Objective: To understand how congenital toxoplasmosis (CT) diagnosis has evolved over the years, we performed a systematic review and meta-analysis to summarize the kind of analysis that has been employed for CT diagnosis. Methods: PubMed and Lilacs databases were used in order to access the kind of analysis that has been employed for CT diagnosis in several samples. Our search combined the following combining terms: "congenital toxoplasmosis" or "gestational toxoplasmosis" and "diagnosis" and "blood," "serum," "amniotic fluid," "placenta," or "colostrum." We extracted data on true positive, true negative, false positive, and false negative to generate pooled sensitivity, specificity, and diagnostic odds ratio (DOR). Random-effects models using MetaDTA were used for analysis. Results: Sixty-five articles were included in the study aiming for comparisons (75.4%), diagnosis performance (52.3%), diagnosis improvement (32.3%), or to distinguish acute/chronic infection phases (36.9%). Amniotic fluid (AF) and placenta were used in 36.9% and 10.8% of articles, respectively, targeting parasites and/or T. gondii DNA. Blood was used in 86% of articles for enzymatic assays. Colostrum was used in one article to search for antibodies. In meta-analysis, PCR in AF showed the best performance for CT diagnosis based on the highest summary sensitivity (85.1%) and specificity (99.7%) added to lower magnitude heterogeneity. Conclusion: Most of the assays being researched to diagnose CT are basically the same traditional approaches available for clinical purposes. The range in diagnostic performance and the challenges imposed by CT diagnosis indicate the need to better explore pregnancy samples in search of new possibilities for diagnostic tools. Exploring immunological markers and using bioinformatics tools and T. gondii recombinant antigens should address the research needed for a new generation of diagnostic tools to face these challenges.

Breastfeeding prevalence in newborns of mothers with COVID-19: a systematic review.

OBJECTIVES: to compare exclusive breastfeeding prevalence versus artificial feeding in newborns of mothers with COVID-19. METHODS: a systematic review of prevalence, according to JBI. Searches in PubMed®, Embase, CINAHL, LILACS and Web of Science™ databases in August 2021. Cross-sectional, longitudinal or cohort studies were selected, without language and time limitations that showed breastfeeding prevalence or that allowed calculation. RESULTS: fifteen articles published in 2020 and 2021, cohort (60%) or cross-sectional (40%) were analyzed. The average of exclusive breastfeeding in mothers with COVID-19 was 56.76% (CI=39.90-72.88), and artificial breastfeeding, 43.23% (CI = 30.99 - 55.88), without statistically significant differences. CONCLUSIONS: despite the recommendations for maintaining breastfeeding, there was a reduction worldwide, when compared to periods prior to the pandemic. With advances in science, these rates have improved, showing the impact of evidence on practices. As limitations, study sources are cited. It is recommended to carry out new studies.

Labor analgesia and its impact on the maternal and perinatal outcomes.

OBJECTIVE: This study aimed to assess adverse maternal and perinatal outcomes in parturients undergoing labor analgesia. METHODS: This was a retrospective cohort study in parturients who underwent labor analgesia. Parturients were categorized into three groups: Group 1 (n=83)-analgesia performed with cervical dilatation ≤4.0 cm; Group 2 (n=82)-analgesia performed with cervical dilatation between 5.0 and 8.0 cm; and Group 3 (n=83)-analgesia performed with cervical dilatation ≥9.0 cm. RESULTS: Analgesia in parturients with cervical dilatation ≥9.0 cm showed a higher prevalence and a 3.86-fold increase (OR 3.86; 95%CI 1.50-9.87; p=0.009) in the risk of forceps delivery. Analgesia in parturients with cervical dilatation ≤4.0 cm showed a higher prevalence and a 3.31-fold increase (OR 3.31; 95%CI 1.62-6.77; p=0.0016) in the risk of cesarean section. Analgesia in parturients with cervical dilatation ≥9.0 cm was associated with a higher prevalence of fetal bradycardia (20.7%), a need for neonatal oxygen therapy (6.1%), and a need for admission to a neonatal intensive care unit (4.9%). Analgesia in parturients with cervical dilatation ≤4 cm was associated with a higher prevalence of Apgar score <7 at 1st minute (44.6%). CONCLUSION: Performing labor analgesia in parturients with cervical dilatation ≤4.0 or ≥9.0 cm was associated with a higher prevalence of adverse maternal and perinatal outcomes.

Ultrassonografia morfológica de primeiro trimestre: importante ferramenta para rastreio de aneuploidias e pré-eclâmpsia / First-trimester morphological ultrasound: important tool for aneuploidy and pre-eclampsia screening

No início do século 20, as altas taxas de mortalidade materna e infantil estimularam o desenvolvimento de um modelo de atendimento pré-natal que mantivesse características parecidas até os dias atuais. Nesse modelo, haveria maior concentração de visitas durante o final do terceiro trimestre de gestação, devido às maiores taxas de complicações nas fases finais da gestação e à dificuldade de prever a ocorrência de resultados adversos durante o primeiro trimestre. Atualmente, a avaliação clínica durante o primeiro trimestre, com auxílio da ultrassonografia e marcadores bioquímicos, pode prever uma série de complicações que acometem a gestação, incluindo cromossomopatias, pré-eclâmpsia, restrição de crescimento fetal, anomalias fetais e trabalho de parto pré-termo.

At the beginning of the 20th century, the high rates of maternal and infant mortality stimulated the development of a model of prenatal care that maintained similar characteristics until the present day. In this model, there would be a greater concentration of visits during the end of the third trimester of pregnancy, due to the higher rates of complications in the final stages of pregnancy and the difficulty in predicting the occurrence of adverse outcomes during the first trimester. Currently, clinical evaluation during the first trimester, with the aid of ultrasound and biochemical markers, can predict a series of complications that affect pregnancy, including chromosomal disorders, preeclampsia, fetal growth restriction, fetal anomalies and preterm labor.

Association between antibiotic prophylaxis and adverse perinatal outcomes in premature rupture of membranes.

OBJECTIVE: The aim of this study was to evaluate the association between antibiotic prophylaxis and adverse perinatal outcomes in premature rupture of membranes. METHODS: This retrospective cohort included pregnant women with premature rupture of membranes (between 24 and 33+6 weeks) who used or did not use prophylactic antibiotics. Pearson's chi-square (χ²) test, Student's t-test, and binary logistic regression were used for statistical analysis. RESULTS: A significant effect was observed in patients with premature rupture of membranes using prophylactic antibiotics regarding amniotic fluid index (p=0.007), deepest vertical pocket (p=0.049), duration of antibiotic therapy (p≤0.001), C-reactive protein level upon admission (p≤0.001), leukocyte count upon admission (p=0.007), and length of stay in neonatal intensive care (p=0.047). A significant association was observed between the abovementioned patients and surfactant use during the neonatal period (p=0.04). A higher prevalence of surfactant use was noted in these patients (20.0 vs. 8.7%; p=0.04). CONCLUSION: No association was found between antibiotic prophylaxis and the presence of adverse perinatal outcomes in pregnant women with premature rupture of membranes between 24 and 33+6 weeks of gestation.

Congenital intra-hepatic porto-systemic shunts diagnosed during intrauterine life: Systematic review.

OBJECTIVE: To describe the ultrasonographic characteristics of congenital porto-systemic venous shunts (CPSS) diagnosed during pregnancy, their outcomes, and their evolution. METHODS: Two independent researchers selected 493 review articles and case reports through the analysis of titles, abstracts, and full text. The PubMed and LILACS databases were searched. Through the application of filters according to the PRISMA protocol, only six articles were used in the research. The following information was collected, when available: gestational age at diagnosis, gender, birth weight, type of shunt, associated anomalies/complications and treatment/progression. RESULTS: The data were obtained from 27 cases, with 22 (82%) fetuses diagnosed with intra-hepatic CPSS and 5 (18%) with extra-hepatic CPSS. The median time of intrauterine diagnosis was 33 weeks. In 12 (57.1%) of the 21 pregnancies evaluated, delivery was preterm. The estimated fetal weight ranged from 1150 to 3760 g, with 4 (25%) cases at <3rd, 3 (18.75%) cases at <10th, 8 (50%) cases at <50th, and 1 (6.25%) case at >97th percentile for gestational age. The most frequent obstetric complication was fetal growth restriction, which occurred in nine (60%) cases. As for postnatal treatment, 19 (70.4%) cases were conservatively treated, and 8 (29.6%) cases required surgical intervention. CONCLUSION: The diagnosis of CPSS still represents a challenge during prenatal care. Its early identification aims to provide guidance to pregnant women and their families, as well as follow-up and anticipation of possible complications, in addition to the evaluation of the mode of delivery and postnatal follow-up, directing the short- and long-term prognosis.

Association of gestational diabetes mellitus and negative modulation of the specific humoral and cellular immune response against Toxoplasma gondii.

In order to evaluate and compare the specific immune response of pregnant women (PW) chronically infected with Toxoplasma gondii, with and without gestational diabetes mellitus (GDM), and the humoral response of their respective newborns (NB), the study was carried out on 81 PW (34 GDM and 47 controls) from whose medical records the results of the oral glucose tolerance test (OGTT) were obtained, and blood samples were collected at the third trimester of pregnancy; also, on 45 NBs (20 GDM and 25 controls) from whom umbilical cord blood samples were obtained. Humoral immunity was analyzed by measuring anti-T. gondii total IgG, IgG subclasses and IgG avidity. To evaluate cellular immunity, peripheral blood mononuclear cells (PBMC) from 32 PW (16 GDM and 16 controls) were cultured, supernatant cytokines were determined, and flow cytometry was performed to analyze the expression at lymphocytes of surface molecules, cytokines and transcription factors. All PW and NBs were positive for total IgG, and the prevalent subclass was IgG1. There was a negative correlation between the OGTT glycemia of PW and the levels of total IgG, IgG1 and IgG avidity. The IgG avidity of the GDM group was significantly lower than the control group. Patients from the GDM group had a higher number of T lymphocytes expressing markers of cell activation and exhaustion (CD28 and PD-1). In the presence of T. gondii soluble antigen (STAg) the amount of CD4+ T cells producing IFN-γ, IL-10 and IL-17 was significantly lower in the GDM group, while there was no difference between groups in the number of CD4+ CD25HighFOXP3+LAP+ functional Treg cells. Additionally, under STAg stimulus, the secretion of IL-17, IL-4, TNF and IL-2 cytokines at PBMCs culture supernatant was lower in the GDM group. In conclusion, there was a correlation between the increase in blood glucose and the decrease in levels of anti-T. gondii antibodies, associated with the decreased IgG avidity in patients who develop GDM. Also, the GDM group had decreased immune responses in Th1, Th2 and Th17 profiles, suggesting an association between GDM and the negative modulation of the humoral and cellular immune responses against T. gondii.

Metastasizing leiomyoma during pregnancy

Uterine leiomyoma is a benign tumor of myometrial tissue which affects women of reproductive age. Its prevalence increases with age and has a peak incidence at the age of forty. The term "metastasizing leiomyoma" refers to a tumor of dense connective tissue and smooth myometrial muscle cells located outside the uterus. This group of tumors can metastasize to different organs, the lung being its main focus. We present the case report of a 33-year-old female gravida 3, para 1, abortus 1, at 11 weeks of pregnancy, with pelvic masses. The diagnosis was metastasizing leiomyoma during pregnancy.

Prenatal diagnosis of diastrophic dysplasia in the second trimester of pregnancy: Two- and three- dimensional ultrasonographic findings

To present a prenatal diagnosis of diastrophic dysplasia in the second trimester of pregnancy using two- (2D) and three-dimensional (3D) ultrasonography. The mother was primigravida and aged 12 years. She underwent the first 2D obstetric ultrasound examination at 27 weeks, showing bilaterally upper and lower limb micromelia, thumb and hallux in bilateral abduction, bilateral talipes equinovarus; hyperlordosis of the lumbar spine, cervical, lumbar, and sacral scoliosis; cervical hyperkyphosis with the misalignment of cervical vertebrae, and straight clavicles. 3D ultrasonography in conventional and HDlive rendering modes confirmed the changes observed in 2D ultrasonography and allowed improved understanding by the parents. At birth, the newborn presented transient respiratory distress and neonatal sepsis. At the time of writing, the child is aged 31 months and under follow-up by the pediatrics department. 3D ultrasound allowed the parents to understand the fetal malformations better, and they received adequate counseling.

Results the prevalence of adherence to postpartum consultation was 34.7%. The reception of the health team during the prenatal and/or birth was observed as a facilitator. The mentioned barriers were the following: forgetfulness, complications with themselves and/or the newborn, transportation difficulty and distance between the service and residence. The factors associated with adherence were the following: postpartum women with higher education, who performed all or part of the prenatal care at the institution, who had pregnancy classified as high risk, who had previous diseases during pregnancy, primigravidae, and who had cesarean delivery. Conclusions and implications for the practice the submitted data made it possible to delineate a profile of the postpartum women who adhered or not to the postpartum return, identifying facilitators and barriers as well as factors associated with greater adherence. It is necessary to rethink assistance to the postpartum period, since consultation is the one of the strategies to prevent maternal death.

Active Versus Expectant Management for Preterm Premature Rupture of Membranes at 34-36 Weeks of Gestation and the Associated Adverse Perinatal Outcomes.

OBJECTIVE: To compare the type of management (active versus expectant) for preterm premature rupture of membranes (PPROM) between 34 and 36 + 6 weeks of gestation and the associated adverse perinatal outcomes in 2 tertiary hospitals in the southeast of Brazil. METHODS: In the present retrospective cohort study, data were obtained by reviewing the medical records of patients admitted to two tertiary centers with different protocols for PPROM management. The participants were divided into two groups based on PPROM management: group I (active) and group II (expectant). For statistical analysis, the Student t-test, the chi-squared test, and binary logistic regression were used. RESULTS: Of the 118 participants included, 78 underwent active (group I) and 40 expectant management (group II). Compared with group II, group I had significantly lower mean amniotic fluid index (5.5 versus 11.3 cm, p = 0.002), polymerase chain reaction at admission (1.5 versus 5.2 mg/dl, p = 0.002), time of prophylactic antibiotics (5.4 versus 18.4 hours, p < 0.001), latency time (20.9 versus 33.6 hours, p = 0.001), and gestational age at delivery (36.5 versus 37.2 weeks, p = 0.025). There were no significant associations between the groups and the presence of adverse perinatal outcomes. Gestational age at diagnosis was the only significant predictor of adverse composite outcome (x2 [1] = 3.1, p = 0.0001, R2 Nagelkerke = 0.138). CONCLUSION: There was no association between active versus expectant management in pregnant women with PPROM between 34 and 36 + 6 weeks of gestation and adverse perinatal outcomes.

OBJETIVO: Comparar o tipo de manejo (ativo versus expectante) para ruptura prematura de membranas (PPROM, na sigla em inglês) entre 34 e 36 semanas e 6 dias de gestação e os resultados perinatais adversos relacionados, em 2 hospitais terciários do sudeste brasileiro. MéTODOS: No presente estudo de coorte retrospectivo, os dados foram obtidos através da revisão dos prontuários de gestantes internadas em dois centros terciários com protocolos diferentes para o seguimento da PPROM. As gestantes foram divididas em dois grupos com base no manejo da PPROM: grupo I (ativo) e grupo II (expectante). Para análise estatística, foram utilizados o teste t de Student, qui-quadrado e regressão logística binária. RESULTADOS: Das 118 gestantes incluídas, 78 foram submetidas a tratamento ativo (grupo I) e 40 a seguimento expectante (grupo II). Comparado ao grupo II, o grupo I apresentou índice de líquido amniótico médio significativamente menor (5,5 versus 11,3 cm, p = 0,002), reação em cadeia da polimerase na admissão (1,5 versus 5,2 mg/dl, p = 0,002), tempo de antibióticos profiláticos (5,4 versus 18,4 horas, p < 0,001), tempo de latência (20,9 versus 33,6 horas, p = 0,001) e idade gestacional no parto (36,5 versus 37,2 semanas, p = 0,025). Não houve associações significativas entre os grupos e a presença de resultados perinatais adversos. A idade gestacional no diagnóstico foi o único preditor significativo de desfecho composto adverso (x2 [1] = 3,1, p = 0,0001, R2 Nagelkerke = 0,138). CONCLUSãO: Não houve associação entre manejo ativo e expectante em gestantes com PPROM entre 34 e 36 semanas e 6 dias de gestação e resultados perinatais adversos.
