Fetal fibronectin (fFN) is a fibronectin protein produced by fetal cells. It is found at the interface of the chorion and the decidua (between the fetal sac and the uterine lining ). Fetal fibronectin is found normally in vaginal fluid in early pregnancy prior to 22 weeks due to normal growth and development of tissues at the junction of the ...
Fetendo or Fetal Endoscopic surgery [1] is a form of fetal intervention in the treatment of birth defects and other fetal problems. The procedure uses real-time video imagery from fetoscopy and ultrasonography to guide very small surgical instruments into the uterus in order to surgically help the fetus. The name Fetendo was adopted for the ...
Antenatal steroids have also been shown to have definite beneficial effect in treating the condition of preterm premature rupture of membranes (PPROM). [8] Similar to its effects on preterm birth, research evidence suggests that the administration of antenatal steroids to patients with PPROM reduces risks of neonatal mortality, intraventricular hemorrhage and respiratory distress syndrome.
There are still some concerns about the efficacy and side effects of a second course of steroids, but the consequences of RDS are so severe that a second course is often viewed as worth the risk. A 2015 Cochrane review (updated in 2022) supports the use of repeat dose(s) of prenatal corticosteroids for women still at risk of preterm birth seven ...
Magnesium sulfate infusion for 24–48 hours to allow maximum efficacy of corticosteroids for fetal lungs and also confer benefit to fetal brain and gut before delivery; One time dose of corticosteroids (two separate administrations, 12–24 hours apart) before 34 weeks; Antibiotics if needed to prevent GBS transmission; Pre-viable < 24 weeks
This provides a much more reliable indication of the fetal well being than external monitoring alone. Internal fetal monitoring is often performed if there is a complication such as maternal disease, or if there is fetal distress or if the mother is being induced. 3. To check the color of the fluid.
A potential benefit of using fetal stem cells over those obtained from embryos is that they side-step ethical concerns among anti-abortion activists by obtaining pluripotent lines of undifferentiated cells without harm to a fetus or destruction of an embryo. These stem cells would also, if used to treat the same individual they came from ...
Fibronectin is a high-molecular weight (~500-~600 kDa) [5] glycoprotein of the extracellular matrix that binds to membrane-spanning receptor proteins called integrins. [6] Fibronectin also binds to other extracellular matrix proteins such as collagen, fibrin, and heparan sulfate proteoglycans (e.g. syndecans).
