The PDF includes details of all of the talks, including one on S4ME's PEM factsheet:
Talk 1: Post-Exertional Malaise - a perspective from the online ME/CFS community of Science for ME
Maree Candish – ME/CFS research advocate & Committee member of Science for ME
Abstract: Science for ME is an online community dedicated to improving the understanding of ME/CFS andrelated conditions. A recent initiative has been the collaborative development of a series of fact sheets on aspects of ME/CFS. Trish Davis led the writing of the second fact sheet which focuses on a core feature of ME/CFS, Post-Exertional Malaise (PEM), and includes input from people with a range of ME/CFS severities. This presentation will cover the content of the fact sheet, defining Post-Exertional Malaise, explaining what it is like to experience it, and noting some implications of PEM for ME/CFS research.
Talk 2: The pathophysiology of PEM, what we know, but importantly, what we don’t?
Mark Faghy – Professor of Clinical Exercise Physiology, University of Loughborough
Talk 3: Failure to capture PEM distorts evidence in ME/CFS and Long COVID trials.
Marjon Wormgoor – Independent researcher & ME/CFS research advocate
Abstract: I will focus on how PEM has often been insufficiently captured, overlooked, or misinterpreted intrials, and how this may lead to intervention benefits being overstated and harms underestimated. This is not a new observation for those working in the field, but it remains insufficiently addressed in study design and interpretation, with important implications for the validity of the evidence base
Talk 4: How to Eat an Elephant: Contemporary Scientific and Clinical Approaches to Post-Exertional Malaise
Todd Davenport – Professor and Chair of the Doctor of Physical Therapy (DPT) Program, Univ of the Pacific
Talk 5: Molecular signals of PEM
Maureen Hanson – Liberty Hyde Bailey Professor in the Department of Molecular Biology and Genetics at Cornell University and Director of the Centre for Enervating Neuroimmune Disease
Abstract: We have probed components of blood samples from ME patients and sedentary healthy individuals taken before and after two successive maximal cardiopulmonary exercise tests in order to search for clues tothe disabling phenomenon. I will describe the insights we have gained as a result of these studies.
