A Perioperative Smoking Cessation Intervention With Varenicline, Counseling, and Fax Referral to a Telephone Quitline Versus a Brief Intervention: A Randomized Controlled Trial.

Background: The effectiveness of perioperative interventions to quit smoking with varenicline has not been compared with brief interventions. Our objective was to determine the efficacy of a comprehensive smoking cessation program versus a brief intervention for smoking cessation.

Methods: In this prospective, multicenter study, 296 patients were randomized to participate in a smoking cessation program (one 10- to 15-minute counseling session, pharmacotherapy with varenicline, an educational pamphlet, and a fax referral to a telephone quitline); or brief advice and self-referral to a telephone quitline.

Estradiol and mental rotation: relation to dimensionality, difficulty, or angular disparity?

Several studies have reported that performance on spatial rotation tests is better at menses than at high estradiol phases of the menstrual cycle in women. These effects are debated because nearly all reports of menstrual cycle variability have relied on a single test, the Mental Rotations Test (MRT, Vandenberg and Kuse, 1978). In the present study, we investigated key features of the MRT that might be responsible for its association with estradiol levels.
