, , , , , This systematic review accompanied by a meta-analysis aimed to estimate the prevalence of syphilis in pregnant women in Brazil and describe its associated factors.
Following the establishment the search strategies and the registration of the review protocol in PROSPERO, we conducted a search for relevant articles in the Pubmed, LILACS, Science Direct, SciELO and Web of Science databases. Our inclusion criteria were cross-sectional studies published between 2005 and 2023, with no language restrictions. The combined prevalence of syphilis infection was estimated using the random effects model in the R Software with a 95% confidence interval (95% CI) and p < 0.01 as statistically significant.
A total of 24 articles were recruited, which together investigated 221,884 women. The combined prevalence of syphilis in pregnant women in Brazil was 1.79% (95% CI: 1.24-2.57%), and the main factors associated with its occurrence were black and brown skin color, low education and factors related to the partner.
There was a high prevalence of syphilis in pregnancy in Brazil, mainly associated with socioeconomic factors.

PURPOSE: To evaluate the influence of maternal complications, prematurity, fetal anthropometric parameters and conditions of the newborn on different degrees of chorioamnionitis. METHODS: We analyzed 90 placentas from deliveries performed at the General Hospital of Triângulo Mineiro Federal University with a diagnosis of inflammation in the anatomopathological exams. We reviewed the medical records to obtain relevant maternal and fetal information. The infections were classified as grade I - deciduitis; grade II - chorioamnionitis; grade III - chorioamnionitis and vasculitis; grade IV - neonatal sepsis and grade V - fetal death and pneumonitis. RESULTS: Among the pregnant women analyzed, 50.0% had no complications, 15.0% had ruptured membranes, 15.0% urinary tract infection, 7.5% hypertensive disorders, 7.5% transvaginal infection, 5.0% hematogenous infection, and 11.1% other complications. More than a half the neonates were males and 72.2% were born at term. Analysis of the degree of chorioamnionitis showed that 56.7% had grade I, 22.2% grade II, 4.4% grade III, 10.0% grade IV, and 6.7% grade V. Data were analyzed statistically by the Χ2 test for qualitative variables and by the Spearman test for correlation analysis. The higher grades of chorioamnionitis were observed in cases of maternal complications. We observed negative correlations between all parameters and the degree of fetal chorioamnionitis, which were significant regarding weight, length, thoracic circumference and Apgar score in the first and fifth minutes. CONCLUSIONS: The different patterns of chorioamnionitis were related to different maternal and fetal clinical features, affecting the life conditions of the newborn and the severity of morphological lesions found in stillbirths.

PURPOSE: To estimate the prevalence of asymptomatic bacteriuria among pregnant women attended at our university prenatal care clinic and to identify probable clinical predictors. METHODS: Across-sectional study was carried out from August 2008 to October 2009 at the Bahiana School of Medicine involving 260 pregnant women without symptoms of urinary tract infection. The following exclusion criteria were considered: presence of clinical signs such as fever, dysuria, vesical tenesmus, lumbar pain, history of active genital bleeding or loss of amniotic fluid, use of antimicrobial agents in the 30 days prior to sample collection, and refusal to participate in the project. The presence of single pathogen bacterial colonization ≥10(5) CFU/mL in the urine sample obtained from the middle jet was considered to be a dependent variable. The predictive factors evaluated were as follows: age, race, marital status, schooling, gestational age, hypertension, anemia, vaginal infection, sickle cell trait and previous history of urinary tract infection, urinary symptoms related to the lower urinary tract (frequency, urgency and nocturia) and data obtained from the urine summary (leukocyturia, increased bacterial flora, hematuria, proteinuria, and presence of nitrite). Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) software version 13.0 and the level of significance was set at p<0.05. Prevalences were expressed as percentage, and the confidence interval considered was 95% (95%CI). RESULTS: The prevalence of asymptomatic bacteriuria was 12.3% (95%CI=8.3-16.3). E. coli was the most frequent etiologic agent (59.4%). Logistic regression indicated that urgency to void (OR=5.99; 95%CI=2.20-16.31; p<0.001); leukocyturia (OR=2.85; 95%CI=1.04-7.83; p=0.042) and increased bacterial flora (OR=10.62; 95%CI=3.95-28.56; p<0.001) were independent predictors of asymptomatic bacteriuria. CONCLUSION: The prevalence of asymptomatic bacteriuria in the studied population was high. The prediction score created for the final logistic regression model has an accuracy of 91.9% for bacteriuria.

PURPOSE: to assess human T-cell lymphotropic virus type I (HTLV-I) seroprevalence among pregnant women attended at Public Health Units in Goiânia-Goiás and some epidemiologic characteristics of the studied group. METHODS: from September/2003 to December/2004, 15,485 pregnant women were submitted to enzyme-linked immunoabsorbent assays (ELISA), to screen HTLV-I, using filter paper - dried blood in, and to confirm the infection, polymerase chain reaction (PCR) of whole blood was performed. The epidemiologic factors evaluated were: average age, age of 30 years and above, schooling less than nine years, marital status and number of pregnancies. The factors average age, age of 30 years and above, and schooling less than nine years were compared between the infected and non-infected pregnant group. Statistical analysis used Fisher's exact test and Student's t test. RESULTS: the found prevalence was 0.1%. The average age among the infected pregnant group was 26.4 years, 43.7% of them being 30 years old and above, and 62.5% with schooling less than nine years. The non-infected group showed an average age of 24.4 years, 15.4% of them being ³ 30 years old and above, and only 41.5% with schooling less than nine years. Significant statistical difference was noticed only regarding age of 30 years and above and schooling less than nine years. CONCLUSION: the study shows that HTLV-I seroprevalence among pregnant women in Goiânia during the studied period was 0.1%. It occurred more among pregnant women who were 30 years old and above and those with schooling of less than nine years.

PURPOSE: to evaluate the prevalence, epidemiological profile (age and origin) and vertical transmission rate of HTLV I/II infection in pregnant women screened by the Pregnant Protection Program of the State of Mato Grosso do Sul Brazil. METHODS: it is a descriptive and transversal study of 32,512 pregnant women submitted to a prenatal screening from November 2002 to October 2003. HTLV I/II infection was diagnosed in all pregnant women by ELISA, confirmed by Western blot and PCR. Congenital HTLV infection was investigated by ELISA test, Western blot and PCR performed on the child's blood sample. The associations between data (age, origin and HTLV infection) were statistically analyzed by the chi2 test considering p<0.05 to reject the null hypothesis. RESULTS: a prevalence of 0.1% (37) 0.1% HTLV I/II among 32,512 pregnant women was found. The mean age of the infected women was 25.4 ± 6.4 years, and 78.4% of them were from other areas than the capital. There was no association between maternal age and the patients' origin and infection. In all the eight evaluated newborns, which represented 21.6% of the sample, HTLV I/II serum antibodies were found. Only one newborn infant was breast-fed. CONCLUSIONS : HTLV I/II prevalence among pregnant women of the State of Mato Grosso do Sul Brazil was lower than the rates reported by endemic HTLV countries. This rate was almost the same as that described for non-endemic areas and in some Brazilian reports. The vertical transmission rate of HTLV I/II was 100%, in spite of breast-feeding having been proscribed. Improving the follow-up of the pregnant women and their newborns in the State is mandatory, since only a few infants were investigated.
