Non-indicated use of prophylactic antibiotics in gynaecological surgery at an academic tertiary medical centre.

Surgical site infections (SSI) are the most common surgical complication. Perioperative antibiotics can reduce SSI when used properly. Despite guidelines from The American College of Obstetrics and Gynecology, non-indicated antibiotic use is widespread which exposes women to unnecessary risks.

Immunologic challenges of human reproduction: an evolving story.

Characterization of the implanting human fetus as an allograft prompted a field of research in reproductive immunology that continues to fascinate and perplex scientists. Paternal- or partner-derived alloantigens are present in the maternal host at multiple times during the reproductive process. They begin with exposure to semen, continue through implantation and placentation, and may persist for decades in the form of fetal microchimerism.

Genetic considerations in recurrent pregnancy loss.

Human reproduction is remarkably inefficient; nearly 70% of human conceptions do not survive to live birth. Spontaneous fetal aneuploidy is the most common cause for spontaneous loss, particularly in the first trimester of pregnancy. Although losses owing to de novo fetal aneuploidy occur at similar frequencies among women with sporadic and recurrent losses, some couples with recurrent pregnancy loss have additional associated genetic factors and some have nongenetic etiologies.
