The Association between Obesity and Premenopausal Breast Cancer According to Intrinsic Subtypes - a Systematic Review.

Obesity is a well-established risk factor for postmenopausal hormone-receptor positive breast cancer. The relationship between premenopausal breast cancer intrinsic subtypes and obesity is not completely elucidated; therefore, this systematic review was conducted to give an overview about the existing evidence. This review followed the PRISMA Statement for Systematic Reviews and Meta-analyses.

Training and qualification in gynecological minimal access surgery: A systematic review.

Minimally invasive surgery demands specific endoscopic psychomotor skills that are usually acquired outside the operating theatre. We present the results of a systematic analysis to identify how simulation is used during training and qualification in minimal access surgery to improve gynecologist's surgical skills. We found that despite the availability of simulation tools along with methods for training and testing specific endoscopic psychomotor and technical skills, there is no clear evidence of the superiority of one tool or method over the others in skill acquisition.
