Rey In 1988 the World Health Organization, Rotary International, UNICEF, and the U.S. Centers for Disease Control and Prevention passed the initiative to eradicate polio globally by the year 2000.

Trial By Error: Some Things I’ve Read Recently: Anil van der Zee on Sex, “Mold Warrior” Johnson, and a Rant Against the Word “Journey”
By David Tuller, DrPH Anil van der Zee says “Fuck M.E.” One aspect of ME and ME/CFS that receives perhaps too little attention is the impact on someone’s sex life. Engaging in sexual activity takes a significant amount of energy—and is therefore likely to trigger post-exertional malaise for many with this illness. Especially for those …

Trial By Error: Journalist Simon Spichak on Lack of Focus on Post-Exertional Malaise in Long COVID Exercise Trials
By David Tuller, DrPH According to the headline of a recent article in The Sick Times, “less than 20% of Long COVID trials involving exercise even mention post-exertional malaise.” The news organization analyzed the registration records for Long COVID clinical trials and found that only a small minority assess or take into account post-exertional malaise (PEM), …
Trial By Error: JAMA Touts Long COVID Exercise Trial with Clinically Insignificant Results; Most LC Exercise Trials Ignore PEM, Per Sick Times

The JAMA headline: “Resistance Training Improves Long COVID Outcomes.” Technically, the headline is true. In the …
