Preterm Delivery Risk Prediction by Measurement of Prenatal Serum Screening Markers

2014-08-27 03:18:08 | BioPortfolio


This protocol seeks to longitudinally collect blood samples from a cohort of pregnant women. The biological specimens will be used to determine the predictive power of biochemical markers routinely used in Down syndrome screening in the assessment of patient's risk of preterm delivery.


The study will investigate whether the levels of individual maternal serum screening biomarkers, their combinations or temporal changes in the level can be associated with an increased risk of preterm delivery. Blood samples at three time points in pregnancy will be collected from the study participants. The first two blood draws will be timed to coincide with the first and second trimester maternal serum testing. The third blood draw will coincide with the screening for gestational diabetes. Pregnancy outcome information will be collected from the physicians and linked to the subject samples.

Subject samples from a case-control patient group will be analyzed by the serum screening biochemical assay. Statistical analyses will be performed to achieve the study objectives.

NOTE: This study is recruiting in Florida, USA. The laboratory data coordination is being performed in Massachusetts, USA and New Mexico, USA. New study locations will be identified on an ongoing basis.

Vaginal Progesterone to Prevent Preterm Delivery in Women With Preterm Labor

The administration of vaginal progesterone, in addition to standard tocolysis, will decrease the risk of delivering prematurely and of recurrent preterm labor. We also hypothesize that the...

Biomechanics Based Prediction of Preterm Delivery

Quantitative information on the biomechanical properties of the ecto-cervix in mid-pregnancy will be compared between women with term vs. preterm delivery. We aim to demonstrate that biome...

Treatment of Preterm Labor With 17 Alpha-Hydroxyprogesterone Caproate

The goal of our research will be to determine the effectiveness of 17 alpha-hydroxyprogesterone caproate (17P) in the treatment of preterm delivery. Treatment with progesterone is emergin...

Prevention of Recurrent Preterm Delivery by a Natural Progesterone Agent

To examine the preterm delivery rate of a preterm delivery high risk group of pregnant women, using once daily natural progesterone agent.

Oral Versus Parental Progesterone in the Management of Preterm Labor

Preterm birth, defined as delivery at less than 37 weeks gestation, complicates approximately 12% of pregnancies in the United States Preterm delivery has been, and remains, the most impo...

Preterm Delivery Phenotypes in Systemic Lupus Erythematosus Pregnancies.

 Women with systemic lupus erythematosus (SLE) are at a greater risk of preterm delivery, many of which may be medically indicated (iatrogenic). We investigated preterm delivery phenotypes in SLE an...

Geographical differences in preterm delivery rates in Sweden: a population-based cohort study.

Preterm delivery is a major global public health challenge. The objective of this study was to determine how the preterm delivery rates differ throughout a country of very high human-development index...

Intentional early delivery versus expectant management for preterm premature rupture of membranes at 28-32 weeks' gestation: A multicentre randomized controlled trial (MICADO STUDY).

Preterm premature rupture of fetal membranes (PPROM) exposes the fetus to preterm birth, and optimal timing for delivery is controversial. The aim of this study was to compare intentional early delive...

Length of the Second Stage of Labor and Preterm Delivery Risk in the Subsequent Pregnancy.

Cervical injury is regarded as an important risk factor for preterm delivery. A prolonged second stage of labor may increase the risk of cervical injury that, in turn, may be associated with increased...

Inflamatory response in pregnant women with high risk of preterm delivery and its relationship with periodontal disease: a pilot study.

Periodontal disease and its inflammatory response have been related to adverse outcomes in pregnancy such as preterm birth, preeclampsia and low birth weight. This study analyzed systemic inflammatory...

Medical and Biotech [MESH] Definitions

The care of a fetus or newborn given before, during, and after delivery from the 28th week of gestation through the 7th day after delivery.

Delivery of the FETUS and PLACENTA under the care of an obstetrician or a health worker. Obstetric deliveries may involve physical, psychological, medical, or surgical interventions.

Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.

Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.

Systems for the delivery of drugs to target sites of pharmacological actions. Technologies employed include those concerning drug preparation, route of administration, site targeting, metabolism, and toxicity.
