Maternal and neonatal morbidity: repeat Cesarean versus a trial of labour after previous Cesarean delivery.

Purpose: The purpose of this study was to perform a meta-analysis comparing the rates of uterine rupture, and other maternal and neonatal complications, between women who undergo a trial of labour (TOL) after a prior Cesarean delivery and those to undergo elective repeat Cesarean delivery (ERCD).

Source: Medline, Cochrane, EMBASE and Google Scholar were searched until May 6, 2015 using the keywords/phrases: trial of labour, Cesarean section, elective, repeat, pregnancy and vaginal birth. Randomized controlled trials (RCTs), two-arm prospective studies, one-arm studies and retrospective studies were included.

A retrospective analysis of the effect of salpingectomy on serum antiMüllerian hormone level and ovarian reserve.

Objective: To determine whether previous salpingectomy is associated with serum antiMüllerian hormone (AMH) level and ovarian reserve in women under 40 years presenting for in vitro fertilization and embryo transfer.

Study Design: We retrospectively compared serum AMH levels measured on the ovulation induction initiation day in patients with unilateral salpingectomy, bilateral salpingectomy, and no tubal surgery, and examined the relationship with length of time after surgery and in vitro fertilization and embryo transfer parameters.

Results: A total of 198 women were included; 83 received unilateral salpingectomy, 41 bilateral salpingectomy, and 74 no tubal surgery.

Symmetric and asymmetric Au-AgCdSe hybrid nanorods.

This paper describes a facile method for synthesis of Au-AgCdSe hybrid nanorods with controlled morphologies and spatial distributions. The synthesis involved deposition of Ag tips at the ends of Au nanorod seeds, followed by selenization of the Ag tips and overgrowth of CdSe on these sites. By simply manipulating the pH value of the system, the AgCdSe could selectively grow at one end, at both the ends or on the side surface of a Au nanorod, generating a mike-like, dumbbell-like, or toothbrush-like hybrid nanorod, respectively.
