Pilot Study of Electronic Uterine Contraction Inhibitor

The objective is to test a novel paradigm for the inhibition of human preterm uterine contractions. The study hypothesis is that human preterm contractions can be safely inhibited with a weak electrical current provided by an electrical inhibition/uterine pacemaker device. Preterm birth is still a major problem. Current methods of preventing the uterine contractions of preterm are limited and associated with many side-effects affecting both the mother and baby. A reli...

Diagnostic Accuracy of Doppler Ultrasound and Role of Uterine Artery Doppler in Diagnostic Accuracy of Doppler Ultrasound and Role of Uterine Artery Doppler in Cases of Placenta Accreta

This study will be conducted on (100) pregnant women diagnosed as placenta previa by ultrasonography and are candidates for either emergency or elective repeated cesarean section or hysterectomy (if the diagnosis of placenta accreta is confirmed). All of those patients are presenting during the period of may 2018 to july 2018 to Kasr-Al Ainy Obstetrics outpatient clinic or casualty department during their 3rd trimester. All of them will be assorted according to certain inclus...

Prediction of Postpartum Hemorrhage With Uterine Artery Doppler Measurement

The aim of the study is to evaluate the uterine artery doppler just before labour in term low risk pregnancies. And to investigate with this measurement if investigators could foreseen the amount of postpartum hemorrhage looking at decreased in the hematocrit values.

Cerclage After Full Dilatation Caesarean Section

CRAFT-OBS: Observational Study; To evaluate subsequent pregnancy risk of preterm birth in women with a history of previous caesarean in established labour. This prospective study using clinically acquired cervical length and quantitative fetal fibronectin data will help establish a predictive model of preterm birth

A Novel Technique for Prediction of Preterm Birth: Fetal Breathing Patterns

Preterm birth refers to a delivery that occurs before 37 weeks of gestation. Identification of those who will eventually deliver in the preterm period is very important. However, few interventions have been proven to prolong pregnancy in women at risk such as cervicovaginal fetal fibronectin (fFN) level or transvaginal cervical length measurements. In a meta-analysis comparing fetal breathing with cervicovaginal fetal fibronectin (fFN) level or transvaginal cervical length meas...

The Placenta Previa and Fetal Weight

Placenta previa is a placenta that implants at lower uterine segment, it occurs in about 0.3-0.5% of pregnancies at term. It is a significant risk for development of maternal morbidity, as well as maternal mortality secondary to maternal hemorrhage . Also, this abnormal placenta has a negative concern about fetal well being due to prematurity and perinatal mortality, in addition to its undesirable effect on fetal growth. Several factors may be behind of the effect of placenta p...

Preterm Birth Prediction by Measurement of Biomarkers in Cervical Vaginal Fluid

The purpose of this study is to determine the predictive value of 7 biomarkers cervical vaginal fluid on future preterm birth in pregnant women whose gestational age are 16 to 24 weeks.

Time to Delivery of Preterm Birth

Preterm birth (babies being born before 34 weeks pregnancy) occurs in approximately 11% of pregnancies; preterm birth can lead to complications for the baby. When mothers are identified as being at risk of going into preterm birth (giving birth within the next 14 days) there are several treatments available that may help reduce the likelihood of complications for the baby. These treatments usually need to be started within 24 hours so it is very important that diagnosing pret...

Determinants of Preterm Birth in Boston Birth Cohort

Early life exposures may lead to adverse effects on health in later life. The Boston birth Cohort study is designed to study a broad array of early life factors and their effects on pregnancy, infancy, and child health outcomes.

The Use of Progesterone to Reduce Preterm Birth

Preterm birth is the most common and costly complication in obstetrics. It complicates up to 11 % of all pregnancies and it is responsible for 70% of sick babies. Recently two studies have shown that giving progesterone (a normal hormone made by the ovaries) prolongs gestation in women who have had a preterm birth in an earlier pregnancy (and therefore are at risk for another early delivery). There are other studies that show that this technique of giving a weekly shot of proge...

Prediction of Preterm Labor by Fetal Adrenal Gland Evaluation

Preterm birth continues to be a major public health problem with lasting family and societal repercussions. Despite tremendous research effort, prevention strategies have failed, and the prevalence of preterm birth in the United States reached 12.3% in 2003. Prematurity causes 70% of fetal/neonatal deaths. 11.4% of births are at < 37 weeks' gestation. The rate of prematurity increases dramatically with the number of fetuses - singletons 10%; twins 54.9%; and triplets 93.6%

Spontaneous Preterm Birth Marker Test

The prediction of preterm birth is beneficial because it initiates early treatment to minimize risk. It defines a population at risk to provide particular treatment and may lead us to a better understanding the mechanisms of preterm birth. The understanding of the mechanisms and etiology consequently leads to the possibility of early intervention and effective management aiming at preventing preterm birth. Five most common interventions for preventing and treating preterm birth...

Effect of Probiotics on the Preterm Delivery Rate in Pregnant Women at High Risk for Preterm Birth

Preterm birth (PB) continues to be the main cause of perinatal morbidity and mortality, with emotional and economic consequences. Despite improvements in health, PB prevalence remains stable, possibly due to complex causes such as maternal age, stress, multiparity, etc. Shortening of the uterine cervix in early stages of gestation is a risk factor for PB. The presence of abnormal vaginal microbiota in the early stages of pregnancy is als a risk factor for PB. However, no studie...
