Filter by:The primary aim of this research is to assess the predictive value of 3D cervical volume and 3D power Doppler indices in predicting pregnancies at risk of preterm labor. Secondary aim: to compare 2D cervical length and 3D cervical length in coronal view for predicting preterm labour.
The aim of this study is to evaluate the benefit of the addition of azithromycin to standard treatments to prolong pregnancy in women having intact membranes and is at risk of or in preterm labour.
Onset of labor in human is initiated by progesterone withdrawal. Over many decades researchers had proposed hypotheses to explain the functional withdrawal of progesterone. These hypotheses were through the sequestration of active progesterone by corticosteroid-binding globulin, a decrease in active progesterone metabolite levels and changes in the ratio of progesterone receptor (PR) isoforms (nuclear progesterone receptors A (nPRA) and nuclear progesterone receptors B (nPRB)). Progesterone performs its action non-genomically through binding to membrane receptors and genomically via binding to nPRs. PRA is the less active or inactive form of progesterone receptors and shorter in amino acid sequence than PRB, the active form of the receptors.
Preterm labor is one of the problems of obstetrics, and is one of the leading cause of neonatal morbidity and mortality. The incidence of preterm birth is around 7 to 9 %. The preterm baby is prone to respiratory, renal, neurologic and gastrointestinal problems. The correct diagnosis should be followed by the early administration of the most effective tocolytic agent with least side effects for both mother and fetus. Nifedipine, a calcium channel blocker, has gained a world-wide popularity recently since it has the least side-effects on both mother and fetus. In the present study, we aimed to evaluate the success rate of tocolytic agent 'nifedipine' on the spontaneous preterm labor of singeton pregnant women with intact amnionic membrane.
To determine whether a novel ultrasonographic marker, uterocervical angle, correlates with risk of spontaneous preterm birth
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.
Magnesium is a known treatment for neuroprotection in preterm labor before 32 week of gestation. High concentration of Magnesium in the blood stream known as cause of conduction abnormalities and ECG changes such us prolonged QT, QRS and PR in about. The goal of our work is to evaluate the PR intervals in embryos after maternal treatment with magnesium during preterm labor.
RESEARCH HYPOTHESIS -Incidence of preterm delivery is lower in women treated with oral micronized progesterone (Utrogestan) as acute tocolysis agent compare to Nifedipine group with fewer maternal side effect
