Filter by:The goal of our research is to increase live birth rates in infertile women and to reduce the incidence of aneuploidy leading to miscarriage and trisomies. We hypothesize that an age related mitochondrial dysfunction reduces the availability of energy in the oocyte and contributes to abnormal segregation of chromosomes during the meiotic division leading to oocyte aneuploidy. Based on preliminary evidence we have obtained in aged mice, we propose that dietary supplementation with Co enzyme Q10 in older women will improve mitochondrial function in the oocytes, leading to a decrease in chromosomal non-disjunction and resulting in embryos with a normal chromosomal complement. Our primary outcome measure will be determination of oocyte chromosome number by multiplex PCR based assay of polar bodies biopsied at the time of IVF. Outcomes of this proposal will enable us to address the mechanisms of ovarian aging and may explain etiology of decreased fertility in older patients. In addition, our work will add to the feasibility of single embryo transfer, thereby avoiding multiple pregnancies and their associated cost to the health care system and to society.
The objective of this application is to identify a pharmacologic agent which helps couples in whom the female partner ovulates regularly successfully obtain their goal of delivering a healthy child, whose use will result in low rates of multiple gestations. The central hypothesis is that, in infertile ovulatory women undergoing ovarian stimulation (OS) and intrauterine insemination (IUI), the use of aromatase inhibitors (AI) will stimulate the ovaries sufficiently to produce no reduction in the rate of pregnancy, while significantly reducing the numbers of multiple gestational pregnancies that result from stimulation with clomiphene citrate (CC) or follicle stimulating hormone (FSH). The rationale for the proposed research is that reduction of multiple pregnancy rates could significantly reduce maternal and neonatal morbidity and mortality, as well as the cost of healthcare for these individuals and society.
The purpose of this study is to determine whether morning bright light therapy is an effective treatment for major depression during pregnancy compared with low-intensity placebo light therapy, when administered 60 minutes daily for 5 weeks.
The purpose of this study is to establish normograms of parameters measured by the LaborPro system, and to test the prediction of these parameters on labor progress and mode of delivery.
The purpose of this study is to determine whether a daily supplement of vitamin D, taking before and during pregnancy, effects child birth weight, pre- and postpartum complication and bone mineral density during lactation.
In order to confirm the feasibility of home monitoring with Monica AN 24, a licensed portable device for measuring fetal and maternal electrocardiogram (ECG), and the feasibility of inpatient monitoring with Monica AN 24 in patients with Propess (a vaginal licensed drug delivery system used for induction of labour), we will perform a pilot study that will include 20 women in each arm. Feasibility of monitoring with Monica AN 24 both in hospital and at home will be confirmed in a pilot study. The success will be defined as at least 10 minutes of continuous satisfactory trace in any given hour in at least 80% of the patient. A main study will then be conducted to assess the feasibility and acceptability of the Propess and Monica AN24package of care for women undergoing induction of labour. The research questions are: 1. Is outpatient induction with continuous monitoring technically feasible? 2. Does the Propess and Monica AN24 care package of care provide adequate clinical information in line with the UK National Institute of Clinical Evidence (NICE) Guideline for Induction of labour? 3. Is outpatient induction a concept that appeals to women? 4. What do women consider to be the advantages and disadvantages of this package of care? 5. What would women consider to be positive and/or negative outcome in future clinical trials of outpatient induction? 6. Do fetuses with abnormal electrocardiogram (ECG) patterns have evidence of subclinically impaired cardiac function (feasibility study)? 7. Do elevated concentrations of white blood cell components in the umbilical cord blood at birth influence fetal electrocardiogram (feasibility study)?
Recent studies have shown that women are more likely to experience pain in many medical situations. During pregnancy, women may experience an increase in pain threshold. This is thought to be related to hormonal changes and an increase in the level of certain natural pain-relieving substances in their bodies. It is important to develop simple tests to identify woman at higher risk for pain so the investigators can help them. Temporal summation is what happens when a person becomes more sensitive to a certain feeling on their skin when it is applied several times over the course of several seconds. The investigators hypothesize that pregnant women show decreased temporal summation and pain scores to venipuncture, compared to non-pregnant women.
The Creighton Model (CrM) FertilityCare System is a natural family planning method that teaches couples to recognize and chart the signs of fertility and infertility in the woman's cycle and to use that knowledge to either achieve or avoid a pregnancy. The method is natural, safe and effective, and it helps the couple understand their fertility. Trained practitioners at FertilityCare Centers teach the Creighton Model across the country, internationally and long distance. Several FertilityCare Centers and the University of Utah are conducting a study to evaluate the effectiveness of the Creighton Model (CrM) for new and return users wanting to avoid pregnancy. While past studies have shown that the Creighton Model is a highly effective method, this study will use new ways to measure how well it works. This is important because the knowledge gained will improve comparisons between the Creighton Model and other family planning methods. The study will also explore intentions and behaviors of couples to avoid or achieve a pregnancy. The investigators hypothesize that for the CrM the pregnancy rate during perfect use to avoid pregnancy will be about 1% and the behaviorally determined avoiding-related pregnancy rate for the CrM will be about 6%. The investigators will also evaluate the pregnancy rate during "typical use" without a previously stated intention to conceive (in CrM terms, a mixture of avoiding and achieving-related behavior).
The purpose of this study is to determine whether labor self-efficacy (as determined by scores for the Lederman PSEQ II (self-efficacy scores) impacts the second stage 2 length (nromal vs. prolonged) as determined by quartile ranges for our sample. Other studies have shown that women who experience intense pain in the earliest stages of labor have a higher risk of complications. The investigators want to know if negative thoughts can predict this outcome.
Primary Aim - Evaluate whether human embryo exposure to physiologic levels of oxygen during culture improves the percentage of women who deliver a baby following in vitro fertilization and embryo transfer. Hypothesis to be tested: Physiologic oxygen tension during embryo culture, which approximates the oxygen tension in the fallopian tube and uterus, improves live birth rate in clinical In Vitro Fertilization Embryo Transfer (IVF-ET). Secondary Aims Evaluate whether human embryo exposure to physiologic levels of oxygen during culture during in vitro fertilization and embryo transfer - improves embryo cleavage - improves clinical pregnancy rate - reduces multiple pregnancy rate - reduces miscarriage rate Hypothesis to be tested: Physiologic oxygen tension during embryo culture, which approximates the oxygen tension in the fallopian tube and uterus, improves embryo cleavage and clinical pregnancy rates and reduces miscarriage rates in clinical IVF-ET.
