Sharing science to understand Long COVID

RECOVER Research Review (R3) Seminar Series

The goal of the R3 Seminar Series is to share the RECOVER Initiative’s research findings with researchers and the public. These seminars accelerate scientific discovery by allowing experts to share their latest insights on Long COVID and related conditions. Some R3 sessions also inform the public about other research on Long COVID. You can find recordings of all R3 Seminar sessions in the Previous Seminars section below.

12:00PM Eastern Time

Long COVID after SARS-CoV-2 during pregnancy

Speakers will present findings from two studies about Long COVID risk following SARS-CoV-2 infection during pregnancy and the associated risk factors.  Findings are from the multi-site RECOVER pregnancy cohort and retrospective analysis of electronic health records (EHR), using the PCORNET and N3C databases.

Characterization of Long COVID Among Children and Adolescents, Cohort Insights

During the September 10th RECOVER Research Review (R3) Seminar, RECOVER researchers presented some early findings from the RECOVER Pediatric Observational Cohort study. They presented a symptom-based approach for identifying children and adolescents with Long COVID from a study published in JAMA. View the recording on YouTube.

RECOVER-SLEEP and RECOVER-ENERGIZE – Clinical Trials for Sleep Disturbances, Exercise Intolerance, and Post Exertional Malaise Due to Long COVID

During the June 25th RECOVER Research Review (R3) Seminar, researchers presented details about RECOVER-SLEEP, which included two trials focused on identifying potential treatments for sleep disturbances. Researchers also shared details about RECOVER-ENERGIZE, which included one trial focused on potential treatments for exercise intolerance and one trial examining potential treatments for post-exertional malaise. All the trials were recruiting adults experiencing one or more of these symptoms after having COVID. The presentation also included updates on other RECOVER clinical trials in progress.

SARS-CoV-2 infection during pregnancy and development of Long COVID

During the May 14th RECOVER Research Review (R3) Seminar, researchers presented findings from the RECOVER pregnancy observational cohort and EHR cohort about the association of SARS-CoV-2 infection during pregnancy and development of Long COVID. View the recording on YouTube.

PASC in Children: State of the Science and Future Directions

During the April 23rd, RECOVER Research Review (R3) Seminar, the speakers discussed our current knowledge of Long COVID in children, including epidemiology and risk factors, symptoms, underlying mechanisms that cause symptoms, and functional outcomes. View the recording on YouTube.

Patterns and Prevention of Long COVID: Findings from RECOVER EHR Cohort Studies

During the March 19th RECOVER Research Review (R3) Seminar, research presented findings about vaccine effectiveness against Long COVID in children and the association between SARS-CoV-2 infection and symptoms and conditions in children and adults. View the recording on YouTube.

Understanding Neurological Manifestations of PASC and Cerebral Vascular Injury

During the February 13th RECOVER Research Review (R3) Seminar, several pathobiology study awardees presented about the mechanisms of neurological (brain and nervous system) symptoms of Long COVID. View the recording on YouTube.

RECOVER Observational Studies Consortium: Where we are and where we are headed

During the January 23rd RECOVER Research Review (R3) Seminar, researchers presented on the progress and future directions of the RECOVER Initiative. Speakers from the RECOVER adult, pediatric, and autopsy cohorts provided an overview of the progress to date, what is in the pipeline and the ultimate promise of RECOVER for each of the cohorts. A review of the current state of the science of Long COVID and gaps in knowledge was also discussed. View the recording on YouTube.

Impacts of SARS-CoV-2 on brain, gut, and metabolism

During the December 12th RECOVER Research Review (R3) Seminar, panelists discussed immune features of Long COVID, the relationship between Long COVID and metabolism (chemical reactions that provide the body with energy), and impact of acute and Long COVID on the brain. View the recording on YouTube.

Understanding the role of the immune system in PASC

During the November 14th RECOVER Research Review (R3) Seminar, researchers discussed multiple different biological mechanisms likely underlaid PASC manifestations. This seminar explored several prominent mechanisms that were areas of active study, including persistent SARS-CoV-2 viral reservoirs, abnormal immune system activation, and effects on metabolic pathways.
