Filter by:Women are being asked to participate in a research study that is looking for new methods to understand and predict premature birth (birth before 37 weeks of pregnancy—full term pregnancy is 40 weeks). In this study the investigators will be looking at proteins in vaginal fluid, tissue from the placenta after the baby is born (fetal membranes), and a new form of ultrasound of the mouth of the womb (cervix) that measures its length, volume, and stiffness, in order to try to know who will have a preterm birth and who will reach full term. The investigators will collect the vaginal fluid samples and perform ultrasounds both in the clinic throughout pregnancy in normal women, and from women admitted to the hospital because they are in early labor. The investigators will collect the placental tissue after the baby is born (this is normally discarded). This study will help us to understand the process of preterm birth and the investigators hope that this will eventually allow us to develop better methods to treat preterm labor and prevent the birth of premature babies.
The purpose of this study is to to collect and store blood samples that will be utilized to develop a multimarker test to predict preterm delivery.
The prevalence of preterm birth is rising in most western countries. The causes of preterm birth is not fully understood and seem to be multifactorial. The endocrine and metabolic aspects are scarcely investigated.The main purpose of this study is to test the hypothesis that endocrine and metabolic factors associate to preterm births.
Timely screening and management of modifiable conditions can reduce preterm births, yet providing effective prenatal risk management systems to meet the unique needs of medically underserved populations is complex. If the proposed system proves to be effective in reducing preterm births it can improve maternal and child quality of life as well as reduce the economic burden of preterm births in the U.S.
Working hypothesis and aims: To investigate the association between cervical length in non-pregnant women, and the risk of premature birth. The participants will be recruited from the HaEmek Medical Center delivery room registration. Women delivered between 24-37 pregnancy weeks will be allocated to the study group. The investigators will invite them 3 month or more after delivery to ultrasound examination of the cervical length. The participants in the control group will be the women whom term delivery follows by chronological manner to those in study group. Data of the cervucal length will be collected at the time of the examination.
Placement of a vaginal pessary reduces significantly the rate of spontaneous preterm birth in pregnant women with twins and a short cervical length at 18-22 weeks scan.
Placement of a vaginal pessary reduces significantly the rate of spontaneous preterm birth in pregnant women with short cervical length after an episode of threatened preterm labour.
The purpose of this study is to determine if a nutrient-rich supplement of animal-source foods ingested 5d/wk from pre-conception to term improves maternal nutrient status, decreases infections, and improves birth weight and rates of prematurity compared with supplemental ingestion during pregnancy ( from mid-gestation to term) or routine prenatal care.
This is a randomized placebo controlled trial to evaluate whether antenatal corticosteroids can decrease the rate of neonatal respiratory support, thus decreasing the rate of NICU admissions and improving short-term outcomes in the late preterm infant. The use of antenatal corticosteroids has been shown to be beneficial in women at risk for preterm delivery prior to 34 weeks but has not been evaluated in those likely to deliver in the late preterm period
To evaluate whether daily oral micronized progesterone is effective in preventing recurrent spontaneous preterm birth (RSPB) and whether micronized progesterone use increases maternal serum progesterone levels.
