BACKGROUND
The comparative effectiveness of pre- and post-exposure prophylaxis (PrEP and PEP) for men who have sex with men (MSM) is unclear.
SETTING
We conducted a case-control study of MSM who were initially HIV-uninfected during September 1, 2012-June 30, 2016 at San Francisco's only municipal sexually transmitted diseases (STDs) clinic.
METHODS
Each case was matched with up to 3 controls based on age, baseline visit date, and follow-up time. The primary dependent variable was HIV seroconversion; the primary independent variable was exposure to PrEP, PEP, or neither. Conditional logistic regression was used to calculate odds ratios and 95% confidence intervals.
RESULTS
Of 638 MSM (161 cases and 477 controls), 137 reported ever taking PrEP, 98 reported taking PEP-only, and 403 took neither. PrEP takers had more non-HIV sexually transmitted diseases during the analysis (72.3% vs. 55.1% vs. 42.4% P < 0.01) and were more likely to report receptive anal sex in the past 3 months (86.5% vs. 80.4% vs. 73.0%; P < 0.01). In the adjusted model, PrEP was associated with lower odds of HIV seroconversion (odds ratio 0.24; 95% confidence interval: 0.13 to 0.46) while PEP use had no effect on HIV acquisition compared with taking neither.
CONCLUSIONS
MSM who ever used PrEP demonstrated equal or higher sexual risk compared with those using neither PrEP nor PEP but had 76% lower odds of HIV seroconversion. MSM who used PEP but never PrEP were no less likely to seroconvert than those using neither. MSM should be offered PrEP. PEP users with ongoing risk of HIV infection should be connected to PrEP after PEP.

Background
Video is an increasingly popular medium for consuming online content, and video-based education is effective for knowledge acquisition and development of technical skills. Despite the increased interest in and use of video in medical education, there remains a need to develop accurate and trusted collections of peer-reviewed videos for medical learners.
Objective
We developed the first professional society-based, open-access library of crowd-sourced and peer-reviewed educational videos for medical learners and health care providers.
Methods
A comprehensive peer-review process of medical education videos was designed, implemented, reviewed, and modified using a plan-do-study-act approach to ensure optimal accuracy and effective pedagogy, while emphasizing modern teaching methods and brevity. The number of submissions and views were tracked as metrics of interest and engagement of medical learners and educators.
Results
The Best of American Thoracic Society Video Lecture Series (BAVLS) was launched in 2016. Total video submissions for 2016, 2017, and 2018 were 26, 55, and 52, respectively. Revisions to the video peer-review process were made after each submission cycle. By 2017, the total views of BAVLS videos on www.thoracic.org and YouTube were 9100 and 17 499, respectively. By 2018, total views were 77 720 and 152 941, respectively. BAVLS has achieved global reach, with views from 89 countries.
Conclusions
The growth in submissions, content diversity, and viewership of BAVLS is a result of an intentional and evolving review process that emphasizes creativity and innovation in video-based pedagogy. BAVLS can serve as an example for developing institutional or society-based video platforms.
