Objective: This systematic review and meta-analysis aimed to evaluate the efficacy of cervical pessaries in preventing perinatal mortality and extreme preterm birth in pregnancies characterized by a short cervix. Methods: The analysis included data from nine randomized controlled trials (RCTs), incorporating a total of 3813 participants. These studies compared the use of cervical pessaries against standard care or other interventions in preventing preterm births in women with a short cervix, defined as less than 30 mm. The eligibility criteria for the trials included studies on asymptomatic pregnant women with a short cervix. The primary outcomes analyzed were perinatal mortality and the incidence of preterm birth before 28 weeks of gestation. Results: The results showed an imprecise effect estimate for perinatal mortality (OR = 0.93; 95% CI: 0.54 to 1.62). Similarly, the risk reduction for preterm birth before 28 weeks was also non-significant (OR = 0.76; 95% CI: 0.49 to 1.15). Substantial heterogeneity was observed among the studies (I² = 62%), suggesting variability in the study results, which could have been influenced by differences in the study design, population, and interventions. Conclusions: Although the results were statistically inconclusive and the estimates imprecise, the confidence intervals still span possible benefit and harm. Thus, while the current evidence does not support the routine use of cervical pessaries, it also does not indicate an increased risk of fetal or neonatal mortality.

Introduction To assess the intention of actual pregnancy and its influence on glycated hemoglobin (HbA1c) profile before and during the pregnancy of women with previous diabetes mellitus (DM). Methods Prospective cohort study included pregnant women with previous DM assisted from October/2018 to October/2019. Data were collected with standardized questionnaire and from medical records. Comparisons of variables of interest (Student’s t test, Mann–Whitney or chi-square test) were performed between the group of women who did or denied report having interest to become pregnant. And a logistic regression analysis were performed considering prematurity or fetal/neonatal complication as dependent variables. Results Sixty patients were included, with HbA1c mean of pre-pregnancy, first and third trimesters of 9.3, 8.1 and 6.8%, respectively. 7.7% women had HbA1c ≤ 6.5% in pre-pregnancy and 16.7% in first trimester. 83.3% reported having received guidance on the importance of glucose control and contraception before their current pregnancy. Although 28.3% reported the intention to become pregnant, only 28.3% reported regular use of any contraceptive method before it, none of which had HbA1c in the recommended goal for pregnancy. Glycemic control did not differ between groups intending or not to become pregnant. Women with adequate glycemic control in first trimester had a lower frequency of prematurity (p = 0.015) and fetal complications (p = 0.001), and better control at the end of pregnancy. Discussion Although most of these women reported having had information about the importance of a planned pregnancy, adequate glycemic control of women with diabetes before and during the pregnancy is still not a reality nowadays. It might be necessary to improve medical communication in pregnancy planning.

Até hoje a causa não pode ser determinada na maioria dos casos. Fatores de risco para um novo abortamento podem ser identificados. Entretanto, a força da associação com aborto recorrente não é clara para todos os fatores³. Investigações para o aborto recorrente conduzem a achado de anormalidade em dois terços dos casos, sem que se tenha certeza se essa anormalidade realmente tenha relação com a causa da perda².

We assessed FAS and FAS-L gene polymorphisms and messenger RNA (mRNA) levels in patients with recurrent pregnancy loss (RPL). This case–control study compared 129 women with RPL with 235 healthy multiparous women (control group). Genomic DNA and total mRNA were extracted from whole blood, and polymorphisms genotyping was performed by polymerase chain reaction (PCR). Messenger RNA expression levels were analyzed by real-time PCR. Data were analyzed by chi-square and Fisher exact tests; P < .05 was considered significant. There were no significant differences in the FAS (670 A/G) genotype or allelic frequencies between the RPL and control groups. We found significant differences in the FAS-L (844 C/T) genotype and allelic frequencies between women with RPL and controls. Patients with RPL had significantly higher FAS-L expression. Our data suggest that FAS-L gene polymorphism is associated with increased susceptibility to RPL. Moreover, women with RPL seem to abnormally express FAS-FAS-L molecules.

To assess a possible association between polymorphism of the progesterone receptor gene (PROGINS) and recurrent spontaneous abortion (RSA). 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. PROGINS genotypic frequencies were 72.3% T1T1 and 27.7% T1T2 for the RSA group and 76.4% T1T1, 22.3% T1T2 and 1.3% T2T2 for the control group. There were no differences between groups when the genotype and allele frequencies were analyzed: respectively p=0.48 (OR: 0.8) and p=0.65 (OR: 0.9). Our results suggest that PROGINS polymorphism is not associated with RSA.

PURPOSE: to assess the prevalence of the risk of post-partum depression in women in the post-natal ward of a hospital in São Paulo city, in the southeastern region of Brazil, and analyze the associated factors, including domestic violence (DV). METHODS: this was a descriptive, cross-sectional study. The participants were 133 women with at least 20 weeks of gestation age, who delivered their babies from August to September 2005 in a tertiary maternity in the city of São Paulo (Brazil). They were interviewed using the Portuguese version of the Abuse Assessment Screen for the diagnosis of violence and filled out a self-evaluation questionnaire for post-partum depression (Edinburgh Postnatal Depression Scale). Variables were presented as absolute and relative frequencies. The chi2 or Fisher exact tests were used to analyze possible associations between the variables of interest and post-partum depression. The value of 5% was considered significant. RESULTS: risk for post-partum depression was detected in 24 women (18%). A total of 38.3% of the participants interviewed had a history of abuse. There was an association between DV after they were 15 years old and risk of depression (p=0.036). The prevalence of abuse in the group of women at risk for post-partum depression was 58.3% and this was significantly higher than the 33.9% observed in the control group. CONCLUSIONS: the probability of presenting depression was high among the post-partum women attended at a tertiary maternity in the southeast of Brazil. The DV after they were 15 years old was significantly associated with risk of post-partum depression.OBJETIVO: apurar a freqüência de risco para depressão pós-parto (DP) em puérperas de hospital de São Paulo, região Sudeste do Brasil, e determinar fatores associados - entre eles a violência doméstica (VD). MÉTODOS: estudo descritivo, tipo corte transversal. Participaram 133 mulheres, que tiveram partos com idade gestacional de 20 semanas ou mais, no período de agosto a setembro de 2005, em maternidade terciária em São Paulo (Brasil). Foram entrevistadas empregando-se a versão em português do Abuse Assessment Screen para o diagnóstico de violência e responderam questionário de auto-avaliação do risco de DP (Edinburgh Postnatal Depression Scale). As variáveis foram representadas por freqüências absoluta e relativa. A associação entre as variáveis de interesse e DP foi avaliada pelo teste do chi2 ou exato de Fisher. Adotou-se o nível de significância de 5%. RESULTADOS: o risco de DP foi identificado em 24 puérperas (18%). Das mulheres entrevistadas, 38,3% referiram história de abusos. Observou-se associação entre a ocorrência de VD após os 15 anos de idade e o risco de depressão (p=0,03). A ocorrência de abusos no grupo de mulheres com probabilidade de apresentar DP foi de 58,3%, proporção significativamente maior do que a observada no grupo controle com 33,9%. CONCLUSÕES: a probabilidade de apresentar depressão foi alta entre as puérperas assistidas em maternidade terciária da região Sudeste do Brasil. A VD sofrida após os 15 anos de idade esteve estatisticamente associada ao risco de DP.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de ObstetríciaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de EnfermagemUniversidade de Santo AmaroUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaHospital do Servidor Público Estadual 'Francisco Morato de Oliveira'Universidade Metropolitana de Santos Departamento de ObstetríciaUNIFESP, EPM, Depto. de ObstetríciaUNIFESP, EPM, Depto. de EnfermagemUNIFESP, EPMSciEL
