A clinical trial for non-invasive vagal nerve stimulation failed in improving fatigue in Long COVID. 45 participants used a specific transcutaneous auricular vagus nerve stimulation (taVNS) device, or a sham (placebo), during the four-week trial.

The heart failure drug Ivabradine did not significantly improve symptoms for people with Long COVID and postural orthostatic tachycardia syndrome (POTS), according to preliminary results that RECOVER researchers recently shared at a conference.

More than 150,000 deaths from COVID-19 went uncounted in the U.S. in the first two years of the pandemic, according to a new study in Science Advances. Researchers used machine learning to evaluate death certificates from March 2020 to December 2021, and estimated that 19% more COVID-19 deaths occurred than originally reported.

A large retrospective cohort study found significant healthcare cost increases for Long COVID over five years. The study was shared as a preprint in medRxiv and included the records of over 143,000 people.

Researchers identified high levels of cytokine interferon gamma (IFN-γ) in white blood cells as a potential biomarker for Long COVID. The small study, published in Science Advances, found that symptoms improved when production of IFN-γ (a molecule that plays an important role in immune response) decreased.

A new review in Dovepress states that Long COVID, myalgic encephalomyelitis (ME), and postural orthostatic tachycardia syndrome (POTS) should be classified as neuroimmune disorders.

A large study recently connected “chronic absenteeism” to pediatric Long COVID, further disproving the “immunity debt” talking points from pundits earlier in the pandemic.

One NIH study will test low-dose naltrexone, while other upcoming trials will test larozitide and taurine.

The Food and Drug Administration (FDA) has granted expanded access to the stem cell infusion RegeneCyte for Long COVID.

A large prospective cohort study published in Infectious Diseases found that a majority of people with Long COVID did not recover.
