Filter by:The purpose of this study is to identify whether pregnant women with chronic hypertension are at significantly higher risk of having undiagnosed OSA and should be routinely screened with home sleep tests. The investigators will recruit 120 pregnant subjects between 10-20 weeks gestation from the Duke High Risk Obstetrics Clinic over a 20-month period. They will be enrolled into one of two groups: 1) chronic hypertension (on medication or hypertensive blood pressures documented at 3 clinic visits); 2) normal blood pressure, and not on any treatment for chronic HTN and no history of chronic HTN, and matched for BMI (+/- 3 kg/m2) with the chronic HTN group. The two groups will be matched for BMI to control for the effect of obesity on OSA diagnosis and cHTN. The primary hypothesis, that OSA prevalence differs between patients with chronic HTN and normotensive controls, will be assessed with a two-group two-sided Fisher's exact test. A Fisher's exact test with a 0.05 two-sided significance level will have 92% power to detect the difference between a normotensive OSA rate of 0.10 and a chronic hypertensive OSA rate of 0.40 when the sample size in each group is 50. There are no risks associated with the use of the home sleep test device, but subjects that have a severe latex allergy should not participate, as the device
Progesterone can be given to women at risk for preterm birth, and is advocated by many guidelines as progesterone has been shown to markedly decrease preterm birth, death in newborns, and disability. However, not all eligible women are currently receiving this medication. Thus, there is an urgent need to improve prevention of preterm birth with progesterone. In response to the low number of women receiving this medication, the investigators have designed a potential method to increase progesterone use. This method involves the use of an "alert" programmed into electronic medical records, to prompt doctors to prescribe progesterone to women at risk of preterm birth. This study is a randomized controlled trial that will assess the feasibility of using this "alert", by randomly assigning 8 clinics to either use this alert, or to provide their usual prenatal care. The investigators will then study whether the alert improved prescription of progesterone, and examine neonatal outcomes such as preterm birth and birth weight. Care providers will be asked for their feedback and thoughts about the alert, through questionnaires and structured interviews. The investigators hypothesize that the electronic medical record alert will increase care provider recommendations and prescription of progesterone for women at risk of preterm birth. The investigators hope that this study will lay the groundwork for larger future studies aimed to strengthen health care quality and improve the health outcomes of women and their babies.
It is well established that a breast-feeding women need more protein in their diet compared to non-lactating women, but how much additional protein is needed remains unclear. There is reason to believe that the current Dietary Reference Intake (DRI) recommendations for breast-feeding women are too low. To gain better understanding, we plan to study healthy breast-feeding women 20 - 45 yrs, between 3 - 5 months lactation and 6 - 8 months lactation. We will use the indicator amino acid oxidation technique (IAAO), which is a modern, quick and safe research method.
This study evaluates the efficacy and safety of monthly intermittent preventive treatment using dihydroartemisinin piperaquine (DP) alone or in combination with azithromycin (AZ) compared to sulphadoxine-pyrimethamine (SP) for the prevention of malaria in pregnant women in the second and third trimester.
The hypothesis was that the anovaginal distance (AVD), defined as the distance between the anal mucosa and the vaginal wall at the middle level of the anal canal, is higher in obese women compared with normal weight women. Measuring the AVD with transperineal ultrasound has been shown to have a high interobserver agreement. This study aimed to establish if there was a difference in AVD measured by transperineal ultrasound between obese and normal weight women in active phase of labor at term pregnancy. The second aim was to present normal values for the AVD in active phase of labor at term pregnancy.
This is a grounded theory study aiming to understand women's perception of what influences their confidence for birth during labour and birth. Data is being collected using interviews and social media sources.
This study will aid in the development of a research instrument for rapid and highly sensitive detection of perinatal salivary oxytocin, by non-invasive means. There will be two study cohorts: Induction of labor cohort (20) and Cesarean delivery cohort (5) for a total of 25 participants.The standard clinical protocols for administering oxytocin to human subjects at Lucile Packard Children's Hospital will be followed. Oxytocin will be prescribed and dosed as per standard of care with no change due to study enrollment. The study will only involve sampling of saliva and blood. The general hypothesis to be tested is that 1) the sensor will accurately report the levels of oxytocin in saliva samples as compared with standard reference methods and 2) the sensor yields rapid (<20 minutes) oxytocin results with minimal discomfort to subjects. Overall, this will allow to optimize the administration of oxytocin, and for a better understanding of the blood concentration and effects of oxytocin on mother and child.
This study evaluates the effectiveness of the Transcutaneus Electric Nerve Stimulation (TENS) during the labour. TENS is a low frequency electrotherapy technique, analgesic type, generally used in musculoskeletal pathology. The investigators will have three groups of participants to be administered the TENS, a different dose in two groups, while the third will correspond to placebo. The hypothesis of the study is to verify if the TENS is effective as a non-pharmacological method in the relief of pain during childbirth
Epidemiological studies have suggested that maternal periodontitis affects the fetal-placental unit, with an increased risk of adverse pregnancy outcome. Indeed, it has been suggested that the direct or indirect action of parodontopathogenic bacteria induces an inflammatory cascade that leads to spontaneous premature labor. Also, non-treatment of caries and periodontal disease can lead to acute pain and stress. This may promote self-medication and the inappropriate use of analgesic medications, potentially harmful to the health of the fetus. As part of the prevention of complications of pregnancy associated with oral diseases, the National Agency for Accreditation and Evaluation in Health (ANAES) has set up a system that allows any pregnant woman to consult between the 4th and 7th month of pregnancy, an oral health professional to carry out a complete assessment and free care. This study aims at evaluating this device among pregnant women and healthcare professionals 4 years after its implementation. On the other hand, it will make it possible to look for a possible link between the realization of an oral prenatal follow-up and the outcome of the pregnancy.
The incidence of opioid dependence in pregnancy increased over the last decade from 1.2 to 5.8 per 1,000 hospital births per year.1 While methadone is the current, standard treatment for opioid dependent (OD) pregnant women, buprenorphine recently emerged as an alternative. In a recent clinical trial (MOTHER), buprenorphine was associated with superior neonatal outcomes such as shorter duration of treatment for neonatal abstinence syndrome (NAS) compared to methadone. However, buprenorphine was also associated with greater study discontinuation (33% vs. 18%) and illicit opioid use (33% vs. 23%) compared to methadone. Treatment dropout often leads to relapse and resumption of high-risk behaviors, overshadowing any short-term improvement in neonatal outcomes. Therefore, The goal of this K23 proposal is to conduct a pilot study to establish the feasibility and acceptability of a randomized comparative effectiveness clinical trial comparing office-based buprenorphine vs. federally licensed methadone programs for the treatment of OD pregnant women. A pilot study is critical to develop the outcome measures, assessment tools and participant tracking techniques necessary for a future, large-scale comparative effectiveness clinical trial. An examination of feasibility and acceptability will also allow use to characterize the subpopulations of OD pregnant women willing to participate in treatment randomization, identify patient and provider characteristics associated with established treatment preferences and inform the development of strategies to improve participation and enhance the generalizability of the future large-scale clinical trial.
