Filter by:This project randomizes two different screening strategies for diabetes in pregnancy, among a study population of over 17,500 pregnant women and their babies (over 35,000 total) in a large diverse health maintenance organization (HMO), to determine how diagnosis and treatment based on these two strategies in routine clinical care affects complications for the baby and the mother.
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.
When given intravenously, the local anesthetic lidocaine has been shown to decrease the amount of pain medication patients require when recovering from several types of surgeries. Cesarean delivery is a very common surgery in the United States, effecting more than 1 million women each year. The investigators hypothesize that lidocaine, given during and immediately after a patient undergoes a cesarean section, will help improve a mother's overall recovery experience, as well as positively influence bonding with her new baby.
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.
A prospective observational study to test the feasibility of smartphone enabled uChek urinalysis device to detect biomarkers (protein, microalbumin and protein:creatine ratio) in urine, indicative of preeclampsia/eclampsia at over 22 weeks of gestation and assess attitudes of clinicians towards uChek as a new technology for urinalysis.
Cardiac output (CO) is the volume of blood ejected from the heart and is a product of stroke volume (SV) vs heart rate (HR). It is closely related to Blood Pressure (BP) by the formula CO = Mean Arterial Pressure (MAP) / Systemic Vascular Resistance (SVR). Cardiac output monitoring is well established and validated for guiding fluid administration and resuscitation in intensive care and perioperatively in the non-pregnant population. Available CO monitoring methods may risk maternal health or fetal wellbeing or are unvalidated in the pregnant population. Invasive and semi-invasive methods of measuring CO such as the pulmonary artery catheter, the 'gold standard' require invasive arterial or central access negating their use in all but a select group of labouring women and have potentially serious risks attached to their usage. Echocardiography is a well-established and validated technique requiring no invasive access but the requirement for an experienced operator limits routine usage. It uses an external ultrasound probe to scan the heart. Several novel non-invasive cardiac output monitors have recently come to the market including the estimated cardiac output esCCO monitor (Nihon Kohden) which uses Pulse Wave Transit Time (PWTT) to estimate cardiac output. It requires 3-lead Electrocardiography and pulse oximetry alone which is part of the routine monitoring for high risk patients on the labour ward. The investigators research aims to evaluate the accuracy and precision of the esCCO in pregnant women and subsequently assess its utility during medical interventions such as epidural analgesia or caesarean section. The initial validation will take place in an antenatal clinic where women are assessed using Doppler echocardiography. The investigators will then compare the echocardiography results vs the esCCO results.
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.
This prospective, single centred cohort study evaluates the physiological course of the potentially novel biomarker PSP in pregnant women as well as its predictive role in the development of inflammatory complications during pregnancy.
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.
