We have designed new electromyography sensors for measuring uterine activity. These sensors are directional - they preferentially report uterine muscle contractions at specific locations, called regions. By measuring the synchronization of the regions of the uterus during contractions we intend to non-invasively determine if any patient is in-labor or not-in-labor. Accurately diagnosing true preterm labor allows timely intervention to avoid preterm birth; Accurately diagnosing false preterm labor avoids needlessly treating patients who would not benefit.
The study is to evaluate the accuracy of a test device called "PAMG-1" to see if a pregnant women has ruptured membranes in comparison to standardly used testing methods.
Assessment of correlation between vitamin D level and prevalence of preterm births remains limited. The exact role of vitamin D in preterm birth has not yet been clearly defined ,where some studies showed vitamin D deficiency increased the risk of preterm birth while other studies found no correlation. In this study will try to continue research on this subject.
İn this study Study; Between August 2018 and August 2019, the Ministry of Health, Medeniyet University, Göztepe Training and Research Hospital, Gynecology and Obstetrics Clinic Will be Included for Routine Control Purposes, Single Pregnancies Between 16-24 Weeks and no Known Risk Factors for Preterm Delivery . Each Participant Will be Given Written and Verbal Information About the Work and Will be Informed. Uterocervical Angle Measurement; Dorsolithotomy, Using a Sterilized Vaginal Ultrasonic Probe. It Will be Seen That the Distance Between the Internal Cervical os and the External Cervical os is Inclusive of the Cervical Isthmus That Can be Seen With the Anterior Uterine Wall. The First Line Will be Drawn Between the Internal Cervical os and the External Cervical os. The Second Line Will be Drawn as Passing Through the Internal Cervical Ostia, Parallel to the Anterior Uterine Wall. The Angle Between the Two Lines on the Internal Cervical Vertebra Will be Measured. Patients Will be Followed up Until the End of the 37th Gestational Week. The Gestation Week They Are Giving Birth Will be Recorded. Patients Were Then Classified as Before and After 37 Gestational Weeks and Uterocervical Angle Measurements Between 16-24 Gestational Weeks Were Compared.
The primary objective of the study is to assess the incidence and severity of the periodontal infection of patients with preterm labor. The secondary objective of the study is to analyze the relationship between preterm labor and periodontal infection, using clinical, biochemical and microbiological methods.
The primary purpose of the protocol is to compare the diagnostic accuracy in terms of positive and negative predictive values of Premaquick © (combined detection of IL-6 / IGFBP-1 total / IGFBP-1 native) and Quikcheck fFN ™ (fibronectin detection) tests for prediction of spontaneous delivery within 7 days in women with threatened preterm labor. The study hypothesis is that combined detection of IL-6 / IGFBP-1 total / IGFBP-1 native dice the admission will improve the prediction of delivery compared to the detection of fetal fibronectin alone in women with threatened preterm labor.
Preterm birth is a common problem in obstetric care,with estimates ranging from 5% in several European countries to 18% in some African countries, Preterm labor defined as delivery before 37 completed weeks is the leading cause of perinatal and neonatal morbidity and mortality and strongly related to the developmental and neurological disabilities later in life.. There is still considerable uncertainty regarding the optimal progesterone type, route of administration, dosage and timing of start of therapy to prevent preterm labor in risky women
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).
Study included all pregnant women admitted with threatened preterm labor during the study period. All participants underwent estimation of maternal serum homocysteine level and assessment of uterine artery Doppler indices.
