Regret in the Modern Contraceptive Landscape: Evaluating Regret in Patients Undergoing Tubal Ligation or Bilateral Salpingectomy for Contraception.

Objective: To estimate the prevalence of regret among Canadians undergoing tubal ligation or bilateral salpingectomy for contraception in the context of widely available, highly effective, and tolerable reversible contraceptive methods including long-acting reversible contraceptives.

Methods: We performed an online cross-sectional survey of regret following tubal sterilization using Qualtrics software. A convenience sample was used to recruit Canadian residents between the ages of 18 and 60 years who had undergone tubal ligation or salpingectomy for contraception.

Inhibition of LiCl-induced conditioning of anticipatory nausea in rats following immune system stimulation: comparing the immunogens lipopolysaccharide, muramyl dipeptide, and polyinosinic: polycytidylic acid.

The effects of the bacterial endotoxins, lipopolysaccharide (LPS) and muramyl dipeptide (MDP; Experiment 1), and the viral mimetic, polyinosinic: polycytidylic acid (poly I:C; Experiment 2), on the acquisition of "conditioned gaping" behavior in the rodent model of LiCl-induced anticipatory nausea were examined. Experimentally naïve adult male Long-Evans rats were injected (intraperitoneal, i.p.
