The proposed study is to evaluate if there are specific factors in the pelvic floor functional anatomy which can predict the ability of having a vaginal birth after caesarean section. Physical characteristics of the soft tissue in the female pelvis play an important role in successful vaginal delivery. A "tight" or less distensible pelvic floor muscles may influence mode of delivery, leading to poor labour progression and by compressing foetal head produce CTG abnormality such as decelerations, both resulting in caesarean delivery. One of the main structures of the pelvic floor, the puborectoalis muscle, facilitates the passage of fetal head through the birth canal by stretching and distending. Therefore distensibility of the female pelvic floor influences mode of delivery. Three hundred patients, in the third trimester of pregnancy, will be recruited via the antenatal clinics to minimize any disruption in their pregnancy care provision. Eligible participants are pregnant women who had either one or no vaginal births, or one caesarean section and who can give an informed consent and maintain their autonomy regarding mode of delivery with understanding of the forthcoming study results. Participants will be excluded if they sustain any obstetric complications that may impede on time and mode of delivery including an emergency prelabour caesarean section. Ultrasonographic assessment of the differences in the pelvic characteristics of these women will be used to predict a successful of trial of vaginal delivery after caesarean section (VBAC) in subsequent pregnancies. The results will be used to better inform whether there is a simple (single ultrasound assessment) that can be used to help inform women's choice regarding mode of delivery. Results from this research could be a pioneering blueprint for further studies, as there is very little known about this topic.
The purpose of this study is to examine the impact of a lifestyle intervention on gestational weight gain, postpartum weight loss, and other secondary outcomes relative to a usual care control group.
Cesarean section is the most performed abdominal surgery in women, worldwide. The World Health Organization (WHO) considers 15% of deliveries the ideal rate of this surgery. However, Brazil presents the highest rates of cesarian section in the world, reaching 85% in hospitals and private clinics. The most used technique of cesarean section is the known as Pfannenstiel or Classical technique. In 1996, a new technique was described, called Misgav Ladach or minimally invasive technique. Several studies have show that the minimally invasive technique is faster and promotes lower costs and less intraoperative bleeding. There is no current evidence that this technique is less painful. This study aims to compare the postoperative pain in both techniques,by means of two pain scales: a one-dimensional scale, the Visual Analogue Scale, and a multidimensional scale, the McGill Scale.
This pilot quasi experiment was designed to determine the feasibility of a randomized controlled trial of the oral probiotic combination of Florajen3 (>7.5 x109 L. acidophilus, >6.0 x109. B. lactis, and >1.5 x109 B. longum) taken orally once daily beginning at 28 weeks gestation, against placebo, to reduce the colonization of group B Streptococcus at 36 weeks.
Our goal is to study self-monitoring of smoking as a means to reduce smoking in pregnant women. Investigators hypothesize that more regular self-monitoring, text messages and feedback as provided by home carbon monoxide monitoring device combined with medical feedback on results will reduce smoking during pregnancy compared to only receiving text message and no self-monitoring by home monitoring device and no feedback by home carbon monoxide monitoring device . The periconceptual period is a life period, where given the immediacy of the fetus and future child, a pregnant woman is willing to try and modify potentially harmful behaviors.
Clinical trial on effects of continuous positive airway pressure (CPAP) on glucose levels in pregnant patients with sleep-disordered breathing and gestational diabetes
To evaluate levator ani muscle morphology following normal vaginal delivery and cesarean section (elective and emergent), using three-dimensional (3D) transperineal ultrasound, and to study the effect of mode of delivery on female sexual function.
Aim: To evaluate dolutegravir (DTG) pharmacokinetics in pregnant HIV-infected women Rationale: In developing countries many women present with a new HIV diagnosis in late pregnancy, and are at high risk of transmitting infection during delivery. Moreover, women may acquire NNRTI resistance from primary transmission, or use of nevirapine (NVP) in previous pregnancies. In these circumstances, DTG is likely to be more effective in reducing mother to child transmission of HIV than NNRTI-based regimens. Study design: HIV positive pregnant women presenting with untreated HIV infection in late (≥28 -36 weeks gestation) pregnancy will be randomised 1:1 to receive DTG (50mg once daily) or standard of care (nevirapine or efavirenz) + 2 NRTIs. PK (0-24h) profile will be sampled in third trimester and post-partum. Although this is primarily a PK study (and has been powered as such) randomisation is included to allow comparison of plasma HIV VL responses against standard of care (NVP or EFV) and is essential for evaluation of secondary endpoints of safety and efficacy of DTG in pregnancy.

An overwhelming body of evidence of the protective effect of folic acid supplementation on neural tube defect affected pregnancies led to mandatory folic acid fortification in Canada in 1998. Folate is an important co-factor in the transfer of one-carbon units essential in DNA synthesis, repair, and methylation reactions, aberrations of which have been implicated in the pathogenesis of several chronic diseases including cancer. Epigenetic reprogramming occurs in utero and has the potential to be modulated by the methyl donor supply of which folate is a contributor. Animal studies have shown maternal folate exposure can modulate epigenetic changes in the offspring, however, there is limited evidence of this relationship in humans. The aim of this research is to determine the effects of maternal dietary folate and supplemental folic acid intake during the periconceptional and in utero periods on global and gene-specific DNA methylation in human infants. This is a prospective observational study involving 368 Canadian mother-child pairs recruited from St. Michael's Hospital in Toronto, Ontario. Dietary and demographical information was collected from consenting pregnant women at study baseline (12-16 weeks gestation) and in the third trimester (34-37 weeks gestation). Maternal blood samples were obtained at baseline and prior to delivery and a sample of umbilical cord blood was collected at parturition to measure levels of folate status. Global and gene-specific DNA methylation in umbilical cord blood will be correlated with cord and maternal folate status. The data will be analyzed using separate ordinary least squares (OLS) regressions. Results from this study will contribute to a better understanding of how maternal folate and folic acid intake can modulate epigenetic modifications in the offspring and potentially have an effect on disease susceptibility later in life.
