“…just 3 cases of GBS were identified. So, the results of current study were totally different from some studies of western countries like the study of Lajos in Brazil (7) and Loeb (26) which GBS was the most frequent pathogens in the endocervical culture of PPROM women in their study. In the study which was performed by Lajos and colleagues, 212 PROM cases between 24-42 wk of gestation were evaluated and they found GBS was the most frequent microorganism in endocervical culture (7).…”

“…Maybe there were different sampling method, different method for transferring the samples to the lab and also different culture media in these studies; which can affect the results but; in Lajos in Brazil (7) which used unspecialized culture media, again GBS was the most frequent microorganism (9.4%).…”

Background:One of the most important etiologies in pretermpremature rupture of membranes (PPROM) is cervical bacterial colonization.Objective:This study evaluated cervical bacterial colonization in women with PPROM and the pregnancy outcomes.Materials and Methods:In this cohort study, 200 pregnant women with PPROM at 27-37 wk of gestation who were admitted in an academic hospital of Mashhad University of Medical Sciences from March 2015 to July 2016 were studied. samples were obtained from endocervical canal for detection of routine bacteria and Gram staining. Also, we obtained one blood culture from neonates. Maternal endocervical culture, chorioamnionitis, neonatal intensive care unit admission, neonatal positive blood culture, neonatal sepsis, and mortality were documented. Results:Most common isolated microorganism of endocervical culture were Escherichia coli (24.2%), Coagulase negative Staphylococci (27.2%), Enterococcus and candida each one (11.7%). The prevalence of GBS was only 2.2%. Simultaneous positive blood cultures were seen in 3% of neonates. Among them, Gram-negative bacilli accounted for (66.6%), while Gram-positive cocci and candida made up only (16.7%). Endocervical colonization was associated with a higher admission rate (p=0.004), but there was no significant correlation between endocervical colonization and chorioamnionitis, positive blood culture and neonatal mortality rate.Conclusion:With regard to low GBS colonization rate, appropriate antibiotic regimens should be considered in PPROM cases according to the most prevalent micro organisms of endocervical bacterial colonization. Maybe cervical bacterial colonization had some effects on neonatal outcomes. There was no significant association between endocervical bacterial colonization and chorioamnionitis, positive neonatal blood culture and neonatal mortality.

“…Total por trimestre 100 (36) 100 (63) 100 (68) 100 (167) Khalesi et al 22 avaliou, recém-nascidos e gestantes, e mostrou que 14,9% dos recém-nascidos tinham mães com uma história positiva da ITU durante a gravidez (4,4%, 6,1% e 4,4% durante o 1º, 2º e 3º trimestres, respectivamente), observando relação significativa entre a ocorrência de infecção urinária em recém-nascidos e ITU materna, de modo que a prevalência geral de ITU entre os recém-nascidos de mães afetadas foi significativamente maior do que a observada entre as mães não infectadas (30,0% versus 6,8%) . De acordo com estudos brasileiros realizados por Lajos et al 23 em Sumaré-SP e Silva et al 24 em Tubarão-SC, ITUs na gestação, principalmente cistite e pielonefrite, têm relevante associação com nascimentos prematuros ou ruptura precoce de membranas. Essas e outras complicações citadas na literatura 7,8,25,26,27 que podem ocorrer com a mãe e/ou com o feto reforçam a importância de pesquisas nessa área e a necessidade de rastreabilidade de infecção urinária assintomática ou sintomática ao longo do período gestacional.…”

A pesquisa teve como objetivo avaliar a prevalência de infecção do trato urinário durante a gestação e destacar as principais bactérias contaminantes por trimestre. Foi realizado um estudo transversal, analítico e retrospectivo com avaliação de resultados de uroculturas por trimestre gestacional em banco de dados de um laboratório em Caxias do Sul, RS, Brasil em 2014. Foram avaliados resultados de urocultura de 432 gestantes por trimestre, totalizando, 1296 analises. Observou-se 12,89% de crescimento bacteriano, sendo a Escherichia coli o agente predominante (98,20%). Durante a gestação, 25,46% das pacientes tiveram pelo menos um caso, sendo o primeiro trimestre o de menor frequência (8,33%). Infecções do trato urinário no período gestacional são comuns, principalmente por Escherichia coli. As possíveis complicações reforçam a necessidade de campanhas de prevenção, além da realização de urocultura ao longo do período gestacional para garantia de saúde da gestante e proteção do feto.Descritores: Infecção do Trato Urinário; Gestante; Prevalência; Bacteriúria; Trimestre Gestacional.

“…In addition, the severity of neonatal complications is higher in newborn infants from mothers with intraamniotic infection [12]. Study carried out in the state of São Paulo established an association between positive cervical cultures and maternal and fetal infectious morbidities, such as urinary tract infections and neonatal infections, especially in cases of preterm [13]. There are many studies trying to associate infections such as periodontal disease and bacterial vaginosis with preterm labor and prelabor rupture of membranes.…”

BackgroundThe occurrence of preterm birth remains a complex public health condition. It is considered the main cause of neonatal morbidity and mortality, resulting in a high likelihood of sequelae in surviving children. With variable incidence in several countries, it has grown markedly in the last decades. In Brazil, however, there are still difficulties to estimate its real occurrence. Therefore, it is essential to establish the prevalence and causes of this condition in order to propose prevention actions. This study intend to collect information from hospitals nationwide on the prevalence of preterm births, their associated socioeconomic and environmental factors, diagnostic and treatment methods resulting from causes such as spontaneous preterm labor, prelabor rupture of membranes, and therapeutic preterm birth, as well as neonatal results.Methods/DesignThis proposal is a multicenter cross-sectional study plus a nested case-control study, to be implemented in 27 reference obstetric centers in several regions of Brazil (North: 1; Northeast: 10; Central-west: 1; Southeast: 13; South: 2). For the cross sectional component, the participating centers should perform, during a period of six months, a prospective surveillance of all patients hospitalized to give birth, in order to identify preterm birth cases and their main causes. In the first three months of the study, an analysis of the factors associated with preterm birth will also be carried out, comparing women who have preterm birth with those who deliver at term. For the prevalence study, 37,000 births will be evaluated (at term and preterm), corresponding to approximately half the deliveries of all participating centers in 12 months. For the case-control study component, the estimated sample size is 1,055 women in each group (cases and controls). The total number of preterm births estimated to be followed in both components of the study is around 3,600. Data will be collected through a questionnaire all patients will answer after delivery. The data will then be encoded in an electronic form and sent online by internet to a central database. The data analysis will be carried out by subgroups according to gestational age at preterm birth, its probable causes, therapeutic management, and neonatal outcomes. Then, the respective rates, ratios and relative risks will be estimated for the possible predictors.DiscussionThese findings will provide information on preterm births in Brazil and their main social and biological risk factors, supporting health policies and the implementation of clinical trials on preterm birth prevention and treatment strategies, a condition with many physical and emotional consequences to children and their families.
