Filter by:The purpose of this study to determine the association between postoperative pain after cesarean section and several single nucleotide polymorphisms in SCN9A sodium channels gene.
This study is to review how the uterus heals after having open fetal surgery. Open fetal surgery causes a scar perhaps two: one from the open fetal surgery and a second from delivery by cesarean section; rarely, the same area of your uterus was used for both open fetal surgery and delivery. From other studies of surgery performed on a uterus, some of the uterine scars do not heal well. This study's intervention uses sterile saline to spread open the inside of the uterus. The saline is slowly injected into the uterus using a catheter. An ultrasound called a sonohysterogram is performed to take pictures of the uterus, its inside and the walls of the uterus. In this way, the healed areas from the uterine surgery can be seen with ultrasound and evaluated. This is performed at least 6 months after delivery. Primary Outcome: Measure the depth of the scar and location of the scar 6 months or longer after delivery.
The investigators will try to assess the effect of endometrial injury preceding the intrauterine insemination cycle on the pregnancy rates compared to cycles with luteal phase support and the control group.
The proposed study is a pilot randomized controlled trial (RCT) of an electronic patient decision aid (PDA) for antidepressant use in pregnancy. The overall aim of this pilot RCT is to establish the feasibility of future large international RCT of the PDA's effectiveness.
The primary purpose of this study is to assess the responses of pregnant women and their social network to six videos about health in pregnancy. Our goal is to assess a) acceptability and b) understanding of core messages about healthy eating, exercise and weight gain during pregnancy. We will also assess c) non-clinical sources of health information during pregnancy.
This is a continuation study to KUDOS (NCT00266825). The purpose of this study is to follow-up with participants on the original study to determine if the effects of increasing DHA intake during pregnancy increase cognitive development in 2 to 6 year-old children.
Examination of iron supplements routinely used in pregnancy to compare these with one another regarding effectiveness in the prevention of iron deficiency. Determination of ferritin / hemoglobin every pregnant woman under the first routine check. Classification into one of three subgroups (group 1: iron sulfate, Group 2: iron polymaltose, Group 3: multivitamin- multimineral) depending on the measured values. Repetition of hemoglobin every 8 weeks, at the entrance to birth and postpartum day 1, additional provision of ferritin at the entrance to birth. In addition, registration of each child's birth weight and gestational age.
Season of birth influences pregnancy for reasons that remain unclear however the answer may lie in the amount of sunshine pregnant women are exposed to. Sunshine, or ultraviolet light (UV) exposure is already known to have benefits for health on heart disease, strokes and depression. In pregnancy, relationships between sunshine exposure are evident in birth weight, preterm birth and risk of blood pressure complications. Vitamin D, the UV generated hormone, was thought to be responsible when low vitamin D levels were associated with these pregnancy complications. However, vitamin D replacement is ineffective at preventing these outcomes, and the investigators hypothesise that this is because it is the UV that is beneficial for pregnancy and it is working through a different pathway. A new understanding of skin function is central to this, with a 2014 study showing that exposing an adult to 20 minutes of low dose UV light lowered their blood pressure and improved blood flow. These investigators demonstrated this was a direct effect of UV on the skin and was mediated by nitric oxide, a chemical central to many aspects of pregnancy including blood pressure regulation and uterine activity. The investigators in this study have funding from Tommy's to investigate if a similar effect is seen in pregnancy on the circulation. The design is similar to the previously successful method and volunteers would be recruited from clinical areas during the second trimester. As both resting and warming for 20 minutes have the potential to have similar effects on the circulation, a control arm will expose participants to these without the UV. This pilot study would involve one visit and measurements taken would include heart rate, blood pressure, arteriography, ultrasound of the uterine arteries and blood measurements of nitric oxide levels. Arteriography is performed using a specialised arm cuff and is safe and non-invasive. A subset of these women would be invited to repeat this in the third trimester to investigate for a difference in effect at a later gestation.
Healthy parturients presenting for scheduled cesarean delivery will have blood drawn and measured for microparticles at baseline, immediately after delivery, and at several time points thereafter.
The main purpose of this study is to explore the impact of the birth environment on women's birth experience and relevant birth outcomes in the experimental Labour room compared to a standard Labour room.
