Prevention of shoulder dystocia: A randomized controlled trial to evaluate an obstetric maneuver.

Objective: Shoulder dystocia is a major obstetric emergency defined as a failure of delivery of the fetal shoulder(s). This study evaluated whether an obstetric maneuver, the push back maneuver performed gently on the fetal head during delivery, could reduce the risk of shoulder dystocia.

Study Design: We performed a multicenter, randomized, single-blind trial to compare the push back maneuver with usual care in parturient women at term.

Improved efficiency of heat generation in nonlinear dynamics of magnetic nanoparticles.

The deterministic Landau-Lifshitz-Gilbert equation has been used to investigate the nonlinear dynamics of magnetization and the specific loss power in magnetic nanoparticles with uniaxial anisotropy driven by a rotating magnetic field. We propose a new type of applied field, which is "simultaneously rotating and alternating," i.e.

Acute pancreatitis during pregnancy: a review.

This article aims to draw together recent thinking on pregnancy and acute pancreatitis (AP), with a particular emphasis on pregnancy complications, birth outcomes and management of AP during pregnancy contingent on the etiology. AP during pregnancy is a rare but severe disease with a high maternal-fetal mortality, which has recently decreased thanks to earlier diagnosis and some maternal and neonatal intensive care improvement. AP usually occurs during the third trimester or the early postpartum period.
