Immediate maternal and neonatal effects of low-forceps delivery according to the new criteria of The American College of Obstetricians and Gynecologists compared with spontaneous vaginal delivery in term pregnancies
Article Abstract:
Low-forceps delivery may shorten the second labor stage without apparent side effects for mother and child. Low-forceps delivery is a new category in the 1988 guidelines published by The American College of Obstetricians and Gynecologists. After the head of the fetus reaches the pelvic floor, an instrument shaped like a pair of tongs grasps the head and pulls it from the womb. Researchers compared the outcomes following low forceps or spontaneous delivery among 50 women over a period of six months. There were no adverse events between the two groups of 25 women each. For example, mothers had similar lengths of hospital stays regardless of the type of delivery. Birth weights, low Apgar scores, and the need for neonatal intensive care did not differ among the babies of both groups. Compared to low-forceps procedures, arterial blood pH in the umbilical cords of spontaneously delivered children was lower, resulting in more acidity. This increase in acidity may be a result of longer delivery times rather than birthing method.

Analysis of association between maternal tumor necrosis factor-alpha promoter polymorphism (-308), tumor necrosis factor concentration, and preterm birth
Article Abstract:
The association of tumor necrosis factor-alpha (TNF-alpha) single nucleotide polymorphism (G-308>A) and risk of preterm birth is investigated by performing a systematic review and a meta-analysis. The meta-analysis of the evidence has shown no statistically significant association between a single nucleotide polymorphism in the TNF-alpha (G-308>A) and preterm birth. The analyses of AF-TNF-alpha concentration have shown no increase in TNF-alpha in the presence of the minor allele (A).

Impaired factor XIIa-dependent activation of fibrinolysis in treated antiphospholipid syndrome gestations developing late-pregnancy complications
Article Abstract:
A study to investigate the potential role of impaired factor XII-dependent activation of fibrinolysis in treated antiphospholipid syndrome gestetations developing late-pregnancy complications was conducted. The impaired factor XIIa-dependent activation of fibrinolysis seemed to be the key mechanism related to late-pregnancy complications in patients with the antiphospholipid syndrome.
