Filter by:Objective: To study the natural history of normal pregnancy and the most frequent pregnancy complications responsible for the excessive rate of perinatal morbidity and mortality, in order to develop models to predict the occurrence of these complications of pregnancy at the earliest possible time. The study focuses on the prediction of preterm labor with intact membranes, preterm prelabor rupture of membranes (PROM), preeclampsia, small for gestational age, gestational diabetes, and fetal death. These complications account for a minimum of $30 billion annually in the US alone. Study population: A cohort of pregnant women seeking care at the prenatal clinic of the Perinatology Research Branch in Detroit, Michigan. Design: A prospective observational cohort study of the natural history of women with a normal pregnancy, a history of adverse outcome, or those with a complication in the index pregnancy; therefore, this study will include nulliparous and parous women. Data will be collected at the time of clinic visits and will include interviews, clinical measurements, and ultrasound studies. We will assemble a biorepository of maternal biological fluids (blood, urine, saliva, cervicovaginal fluid, gingival crevicular fluid, swabs to characterize microbiota, amniotic fluid when a clinically indicated amniocentesis is performed). Placentas will be collected at the time of delivery as well as umbilical blood, and swabs to characterize the neonatal microbiota. We will use a retrospective case control and case-cohort design to generate models for the prediction of the most common pregnancy complications. These models will be developed by classifying obstetrical complications according to clinical presentation and histologic placental lesions. Models will be developed and subsequently validated in an independent cohort. Outcome measures: The goal is to develop sensitive, specific, and parsimonious predictive models to identify the patients at risk for developing complications of pregnancy using a combination of clinical and biological markers (biochemical and biophysical).
Understanding critical periods during which people are at risk to gain weight or display unhealthy changes in energy balance related behaviour, i.e. eating, physical activity and sedentary behaviour, can facilitate the development of weight gain prevention programs. Although the transition to parenthood is associated with pregnancy-related weight gain and retention in women, evidence on the effect of having a first child on men's body weight is lacking. It is also unclear whether pregnancy-related weight gain and retention cohere with unfavourable changes in body composition and energy balance related behaviour in both women and men transitioning to parenthood. Using a mixed-methods design, the investigators aim to provide insight into this critical life phase. An observational follow-up study will be used to investigate changes in body weight, body composition and energy balance related behaviour among couples from pre-conception to one year postpartum, and to identify those most at risk for excessive weight gain.
Randomized controlled trial to investigate the impact of a pregnancy-specific mobile phone application on the knowledge of specific pregnancy topics and guidelines.
The aim of this study was to investigate salivary and gingival crevicular fluid (GCF) levels of IL-17A, IL-17E, IL-6 AND IL-23 during 2/3 trimester of pregnancy and after delivery.
This is a randomized controlled single blinded crossover study to compare fetal vibroacoustic stimulation with a handheld device to a mobile phone application designed for this study. The handheld device, the Corometrics model 146, was previously marketed and sold for fetal stimulation and is modeled after devices used as artificial larynxes. The mobile phone application uses an iPhone's built in vibration with acoustic stimulation from the speaker at 2,000 Hz frequency at a sound level of 74 decibels when measured at 1 meter distance. The investigators' hypothesis is that the mobile phone application will elicit a fetal response (defined as one or more fetal heart rate accelerations in 15 minutes) at a similar rate to that of the handheld device. Fetal vibroacoustic stimulation is commonly used during antenatal tests of fetal well being such as a non-stress test. Fetal vibroacoustic stimulation works by arousing the fetus to a state of wakefulness during which reassuring fetal movements and associated fetal heart rate accelerations occur. During a non-stress test, two or more fetal heart rate accelerations in 20 minutes constitutes a reassuring test. Fetal vibroacoustic stimulation has been shown to decrease the false positive rate of non-stress testing without increasing the false negative rate. This study will compare the frequency that one or more fetal heart rate accelerations occur in the 15 minutes after vibroacoustic stimulation with the Corometrics-146 fetal acoustic stimulator compared to after vibroacoustic stimulation with a mobile phone application designed for the study.
The study is a population based prospective cohort study designed to collect data on pregnancy outcomes and events of interest among women immunized with Afluria during pregnancy.
The proposed project will test the effectiveness of the novel delivery of an established tobacco cessation treatment among pregnant women in Kentucky. Tobacco use during pregnancy is one of the most modifiable risk factors associated with poor birth and maternal outcomes and yet smoking prevalence among pregnant women in Kentucky is among the highest in the county and estimated to be twice that of the national average, with no meaningful declines observed in twenty years.
The study is a population based prospective cohort study designed to collect data on pregnancy outcomes and events of interest among women immunized with the TIVc or QIVc vaccine during pregnancy.
Back pain is one of the most common complaints in pregnancy. It is caused by the growing pregnant abdomen which then strains the lower back and pelvis. Often Obstetricians recommend rest, Tylenol, pelvic support belts, or exercise. Typically, these do not provide the patient much relief. A physical therapy treatment known as soft tissue mobilization (tSTM) has been shown to be helpful in treating various types of pain. This study will explore whether tSTM can improve back pain in pregnancy.
Clearblue Connected Ovulation Test System (COTS) has been designed for home use by women who are either planning or trying for a pregnancy. This study will determine the difference in pregnancy rate of female volunteers seeking to get pregnant who use COTS in comparison to those not using an ovulation product to assist with conception.
