, , , , , , , • The balanced vaginal microbiome is the main factor defending the vaginal environment against infections. Lactobacilli play a key role in this regard, maintaining the vaginal pH within the normal range (3.8 to 4.5).
•Hormonal and immune adaptations resulting from pregnancy influence changes in the vaginal microbiome during pregnancy.
•An altered vaginal microbiome predisposes to human immunodeficiency virus (HIV) infection.
•Bacterial vaginosis is the main clinical expression of an imbalanced vaginal microbiome.
•Vulvovaginal candidiasis depends more on the host’s conditions than on the etiological agent.
•Trichomonas vaginalis is a protozoan transmitted during sexual intercourse.
•The use of probiotics is not approved for use in pregnant women.

, , , , , , , , , , , , , , , , , , , , , , To evaluate the impact of the race (Black versus non-Black) on maternal and perinatal outcomes of pregnant women with COVID-19 in Brazil. Methods This is a subanalysis of REBRACO, a Brazilian multicenter cohort study designed to evaluate the impact of COVID-19 on pregnant women. From February2020 until February 2021, 15 maternity hospitals in Brazil collected data on women with respiratory symptoms. We selected all women with a positive test for COVID-19; then, we divided them into two groups: Black and non-Black women. Finally, we compared, between groups, sociodemographic, maternal, and perinatal outcomes. We obtained the frequency of events in each group and compared them using X2 test; p-values < 0.05 were considered significant. We also estimated the odds ratio (OR) and confidence intervals (CI).
729 symptomatic women were included in the study; of those, 285 were positive for COVID-19, 120 (42.1%) were Black, and 165 (57.9%) were non-Black. Black women had worse education (p = 0.037). The timing of access to the health system was similar between both groups, with 26.3% being included with seven or more days of symptoms. Severe acute respiratory syndrome (OR 2.22 CI 1.17–4.21), intensive care unit admission (OR 2.00 CI 1.07–3.74), and desaturation at admission (OR 3.72 CI 1.41–9.84) were more likely to occur among Black women. Maternal death was higher among Black women (7.8% vs. 2.6%, p = 0.048). Perinatal outcomes were similar between both groups.
Brazilian Black women were more likely to die due to the consequences of COVID-19.

PURPOSE: to investigate the association between gene polymorphism of the progesterone receptor (PROGINS) and the risk of premature birth. METHODS: In this case-control study, 57 women with previous premature delivery (Case Group) and 57 patients with delivery at term in the current pregnancy and no history of preterm delivery (Control Group) were selected. A 10 mL amount of peripheral blood was collected by venipuncture and genomic DNA was extracted followed by the polymerase chain reaction (PCR) under specific conditions for this polymorphism and 2% agarose gel electrophoresis. The bands were visualized with an ultraviolet light transilluminator. Genotype and allele PROGINS frequencies were compared between the two groups by the χ2 test, with the level of significance set at value p<0.05. The Odds Ratio (OR) was also used, with 95% confidence intervals. RESULTS: PROGINS genotypic frequencies were 75.4% T1/T1, 22.8% T1/T2 and 1.8% T2/T2 in the Group with Preterm Delivery and 80.7% T1/T1, 19.3% T1/T2 and 0% T2/T2 in the term Delivery Group. There were no differences between groups when genotype and allele frequencies were analyzed: p=0.4 (OR=0.7) and p=0.4 (OR=0.7). CONCLUSIONS: the present study suggests that the presence of PROGINS polymorphism in our population does not constitute a risk factor for premature birth.

PURPOSE: to assess a possible association between polymorphism of the progesterone receptor gene (PROGINS) and recurrent spontaneous abortion (RSA). METHODS: in this case-control study, 85 women with at least three previous spontaneous abortions without an identifiable cause (RSA Group) and 157 women with at least two previous term pregnancies without pathologies and no previous miscarriage (Control Group) were selected. An amount of 10 mL of peripheral blood was collected by venipuncture and genomic DNA was extracted by the DTAB/CTAB method, followed by the polymerase chain reaction (PCR) under specific conditions for this polymorphism and by amplification by 2% agarose gel electrophoresis. The bands were visualized with an ultraviolet light transilluminator and the gels were photographed. Differences in the PROGINS genotype and allele frequencies between groups were analyzed by the χ2 test, with the level of significance set at p<0.05. The Odds Ratio (OR) was also used, with 95% confidence intervals 95%CI. RESULTS: PROGINS genotypic frequencies were 72.3% T1T1 and 27.7% T1T2 for the RSA group and 764% T1T1, 22.3% T1T2 and 1.3% T2T2 for the control group. There were no differecnes between groups when the genotype and allele frequencies were analyzed: respectively p=0.48 (OR: 0.8) and p=0.65 (OR: 0.9). CONCLUSIONS: our results suggest that PROGINS polymorphism is not associated with RSA.

PURPOSE: to evaluate the diagnostic accuracy of hysterosalpingography (HSG) and transvaginal sonography (TVS) in terms of detecting uterovaginal anomalies in women with a history of recurrent miscarriage. METHODS: eighty patients who presented two or more consecutive miscarriages were submitted to HSG, TVS and hysteroscopy (HSC). The following diagnoses were considered separately: uterine malformations, intrauterine adhesions and polypoid lesions. Hysteroscopy was the gold standard. The matching among the different methods was evaluated by the kappa coefficient and its significance was tested. The significance level was 0.05 (alpha=5%). Sensitivity, specificity, positive and negative predictive values, with 95% of statistical confidence interval, were calculated. RESULTS: uterovaginal anomalies were detected in 29 (36.3%) patients: 11 (13.7%) were uterine malformations, 17 (21.3%) intrauterine adhesions and one (1.3%) a polypoid lesion. The global matching between HSG and HSC was 85.5%, while between TVS and HSC it was only 78.7%. The best accuracy of HSG appeared to be for the diagnosis of uterine malformations and intrauterine adhesions (diagnostic accuracy of 97.5 and 95%, respectively). For the diagnosis of polypoid lesions, HSG had a diagnostic accuracy of only 92.5%, due to the low rate of positive predictive value (14.3%). TVS had a worse accuracy for all diagnoses, 93.7% for the diagnosis of uterine malformations and 85% for intrauterine adhesions, due to low sensitivity. CONCLUSIONS: histerosalpingography showed a good diagnostic accuracy for the diagnosis of uterine cavity diseases. TVS had good specificity, but with low sensitivity.

OBJECTIVE: evaluation of fetomaternal hemorrhage (FMH) in patients who would need Rh alloimmunization with anti-D immunoglobulin (300 mug) prophylaxis after early miscarriage. METHOD: we included in the study Rh (D) negative blood group patients with positive or unknown Rh (D) partners, who had had a miscarriage up to 12 weeks of gestation, and had been admitted to hospital for uterine curettage. After this procedure 5 ml of venous blood was collected from the patients and the rosette test was applied to screen which patients would need quantitative determination of fetal blood transferred to the maternal circulation, by the Kleihauer-Betke test (K-B). RESULTS: out of 26 patients evaluated the rosette test was positive in one , who showed an FMH of 1.5 ml in the K-B test. CONCLUSIONS: the dose of anti-D immunoglobulin used in cases of miscarriage up to 12 weeks of gestation should be substantially reduced. The availability of preparations of 50 mug is recommended, for a more inexpensive and rational treatment.
