We sought to investigate whether women present adequate knowledge of the main pelvic floor disorders (PFDs) (urinary incontinence - UI, fecal incontinence - FI, and pelvic organ prolapse - POP).
sources A systematic review was performed in the MEDLINE, PEDro, CENTRAL, and Cochrane databases for publications from inception to April 2018. Selection of studies A total of 3,125 studies were reviewed. Meta-analysis was not possible due to the heterogeneity of primary outcomes and the diversity of instruments for measuring knowledge. The quality of the articles included in the analysis was evaluated with the Newcastle-Ottawa Scale (NOS) adapted for cross-sectional studies.
Two authors performed data extraction into a standardized spreadsheet.
Nineteen studies were included, comprising 11,512 women. About the methodological quality (NOS), most of the studies (n= 11) presented a total score of 6 out of 10. Validated questionnaires and designed pilot-tested forms were the most frequently used ways of assessing knowledge. Some studies were stratified by race, age, or group minorities. The most used questionnaire was the prolapse and incontinence knowledge questionnaire (PIKQ) (n= 5). Knowledge and/or awareness regarding PFD was low to moderate among the studies. Urinary incontinence was the most prevalent PFD investigated, and the most important risk factors associated with the lack of knowledge of the pelvic floor were: African-American ethnicity (n= 3), low educational level (n= 4), low access to information (n= 5) and socioeconomic status (n= 3).
Most women have a gap in the knowledge of pelvic floor muscle dysfunctions, do not understand their treatment options, and are not able to identify risk factors for these disorders.

Fetal growth restriction (FGR) diagnosis is often made by fetal biometric ultrasound measurements orDoppler evaluation, but most babies are only diagnosed after birth, using the birth weight as a proxy for intrauterine development. The higher risks of neurodevelopmental delay, metabolic syndrome, and cardiovascular illness associated with FGR impose a shift on the focus during pregnancy. New methodological approaches, like metabolomics, can provide novel biomarkers for intrauterine fetal development. Recent evidence on metabolites involved with fetal growth and weight show a consistent role played by lipids (especially fatty acids), amino acids, vitamin D and folic acid. Fetal energy source andmetabolism, structural functions, and nervous system functioning need further evaluations in different populations. In the near future, the establishment of a core set of outcomes for FGR studies may improve the identification of the role of each metabolite in its development. Thus, we will concretely progress with the perspective of a translational capacity of metabolomics for this condition.

, The objective of this review was to analyze the impact on ovarian reserve of the different hemostatic methods used during laparoscopic cystectomy.
The studies were identified by searching electronic databases (MEDLINE, Embase, Cochrane, LILACS) and scanning reference lists of articles.
We selected clinical trials that assessed the influence of hemostatic techniques on ovarian reserve in patients with ovarian cysts with benign sonographic appearance submitted to laparoscopic cystectomy by stripping technique. The included trials compared different laparoscopic hemostatic techniques: suture, bipolar electrocoagulation, ultrasonic energy and hemostatic sealants. The outcomes evaluated were level of serum anti-Mullerian hormone (AMH) and antral follicle count (AFC). The possibility of publication bias was evaluated by funnel plots.
Twelve trials involving 1,047 patients were evaluated. Laparoscopic suturewas superior to bipolar coagulationwhen evaluating serum AMHand AFC, in the 1st, 3rd, 6th and 12thmonth after surgery. In the comparison between bipolar and hemostatic sealants, the results favored the use of hemostatic agents. The use of ultrasonic energy was not superior to the use of bipolar energy.
We recommend suture for hemostasis during laparoscopic cystectomy.

, To investigate the relationship between maternal exposure to alcohol and low birthweight (LBW).
The literature search was performed in January 2017 using the following electronic databases: Medline, Embase, LILACS, SciELO, Web of Science, Scopus, CINHAL, Proquest, and PsychInfo. The search strategy used the following terms: alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol addiction/ use/abuse/consumption, light/moderate/social/low drinking, low birthweight, case-control studies, retrospective studies, and cohort studies. No restrictions regarding language or publication date were considered. The literature search yielded 2,383 articles, and after screening and eligibility assessment, 39 articles were included in the systematic review, and 38 studies were included in the meta-analysis.
Maternal alcohol consumption was associated with LBWamong retrospective cohort studies (relative risk [RR] = 1.37; 95%CI [confidence interval]:1.10-1.77; I2 = 98.4%; p < 0.01). Prospective cohort studies (RR = 1.11; 95%CI: 0.98-1.25; I2 = 81.5%; p < 0.01), and case-control studies (odds ration [OR] = 1.16; 95%CI: 0.68-1.97; I2 = 61.2%; p = 0.05) showed no association between alcohol and LBW.No publication bias was identified, and the meta-regression showed that the sample size influenced the high heterogeneity among retrospective cohort studies. The subgroup analysis showed differences in association between groups when compared by sample size, type of adjustment, or crude measures and publication year.
We have not found an association between alcohol consumption during gestation and LBW in the analysis in all of the subgroups. In addition, we have found a high heterogeneity between the primary studies, which is related to methodological differences in the conduction of these studies.

The hypothesis of fetal origins to adult diseases proposes that metabolic chronic disorders, including cardiovascular diseases, diabetes, and hypertension originate in the developmental plasticity due to intrauterine insults. These processes involve an adaptative response by the fetus to changes in the environmental signals, which can promote the reset of hormones and of the metabolism to establish a “thrifty phenotype”. Metabolic alterations during intrauterine growth restriction can modify the fetal programming. The present nonsystematic review intended to summarize historical and current references that indicated that developmental origins of health and disease (DOHaD) occur as a consequence of altered maternal and fetal metabolic pathways. The purpose is to highlight the potential implications of growth factors and adipokines in “developmental programming”, which could interfere in the development by controlling fetal growth patterns. These changes affect the structure and the functional capacity of various organs, including the brain, the kidneys, and the pancreas. These investigations may improve the approach to optimizing antenatal as well as perinatal care aimed to protect newborns against long-termchronic diseases.

, To identify the quality of life (QoL) assessment instruments related to the health of women with fecal incontinence (FI) or anal incontinence (AI).
Systematic review conducted in the Virtual Health Library (VHL), PubMed and Cochrane Library databases. The descriptors used were: Questionnaire, Questionnaires, Quality of life, validation, validation Studies, anal incontinence, fecal incontinence and constipation. The search was performed between December 26, 2017 and the beginning of January 2018. The limits used were female gender.
Initially, 5,143 articles were obtained in the search. The articles of validation for Portuguese of questionnaires for the evaluation of the impact of FI/AI on the QoL of women were considered eligible.
The article search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines.
Of the 5,143 articles, only 2 fulfilled the inclusion and exclusion criteria: Fecal Incontinence Quality of Life (FIQL) and the Wexner scale (WS). The FIQL evaluates the QoL related to FI, not covering flatus incontinence. The WS assesses flatus incontinence and the severity of the AI. The WS obtained an interclass correlation coefficient (ICC) of 0.932 and a Cronbach α coefficient > 0.90. The FIQL obtained intraexaminer and interexaminer reproducibility ranging from 0.929 to 0.957 and from 0.944 to 0.969, respectively.
The WS and the FIQL have satisfactory reliability and validity for use during gynecological consultations.

, Diabetes during pregnancy has been linked to unfavorable maternal-fetal outcomes. Human insulins are the first drug of choice because of the proven safety in their use. However, there are still questions about the use of insulin analogs during pregnancy. The objective of the present study was to determine the effectiveness of insulin analogs compared withhuman insulin in the treatment of pregnant women with diabetes througha systematic review withmeta-analysis. The search comprised the period since the inception of each database until July 2017, and the following databases were used:MEDLINE, CINAHL, EMBASE, ISIWeb of Science, LILACS, Scopus, SIGLE andGoogle Scholar.We have selected 29 original articles: 11 were randomized clinical trials and 18 were observational studies.We have explored data from 6,382 participants. All of the articles were classified as having an intermediate to high risk of bias. The variable that showed favorable results for the use of insulin analogs was gestational age, with a mean difference of - 0.26 (95 % confidence interval [CI]: 0.03-0.49; p = 0.02), but with significant heterogeneity (Higgins test [I2] = 38%; chi-squared test [χ2] = 16.24; degree of freedom [DF] = 10; p = 0.09). This result, in the clinical practice, does not compromise the fetal well-being, since all babies were born at term. There was publication bias in the gestational age and neonatal weight variables. To date, the evidence analyzed has a moderate-to-high risk of bias and does not allow the conclusion that insulin analogs are more effective when compared with human insulin to treat diabetic pregnant women.

To evaluate if performing anti-incontinence procedures during surgical anterior and/or apical prolapse correction in women with asymptomatic urinary incontinence (UI) may prevent stress urinary incontinence (SUI) postoperatively.
We have performed a systematic review of articles published in the PubMed, Cochrane Library, and Lilacs databases until March 31, 2016. Two reviewers performed the data collection and analysis, independently. All of the selected studiesweremethodologically analyzed. The results are presented as relative risk (RR), with a 95% confidence interval (CI).
After performing the selection of the studies, only nine trials fulfilled the necessary prerequisites. In the present review, 1,146 patients were included. Altogether, the review included trials of three different types of anti-incontinence procedures. We found that performing any anti-incontinence procedure at the same time of prolapse repair reduced the incidence of SUI postoperatively (RR = 0.50; 95% CI: 0.28-0.91). However, when we performed the analysis separately by the type of anti-incontinence procedure, we found different results. In the subgroup analysis with midurethral slings, it is beneficial to perform it to reduce the incidence of SUI (RR = 0.08; 95% CI: 0.02-0.28). On the other hand, in the subgroup analysis with Burch colposuspension, there was no significant difference with the control group (RR = 1.47; 95% CI: 0.28-7.79]).
Performing any prophylactic anti-incontinence procedure at the same time as prolapse repair reduced the incidence of SUI postoperatively. The Burch colposuspension did not show any decrease in the incidence of SUI postoperatively.
