Here’s what’s happening this week in research:
🩸 Two studies on potential biomarkers for myalgic encephalomyelitis (ME) were published this month. A Nature Medicine multi-omics study assessed numerous samples and clinical data from 153 people with ME over four years, compared them with 96 controls, and trained an artificial intelligence model, BioMapAI, that predicted the disease with high accuracy. Analyses of immune cells and microbiome data matched symptom severity. “This is real biological dysregulation,” one of the authors said in a press release. A second study in the Journal of Translational Medicine found that a molecule called SMPDL3B may also serve as a potential biomarker for ME.
🧠 Stellate ganglion blocks, a procedure where an anesthetic is injected into nerves in the neck, may help reduce the severity of some symptoms of Long COVID and ME, according to two small studies. One retrospective survey study published in Cureus assessed 52 participants who underwent the treatment. They found that it helped with headaches, dizziness, and “brain fog,” but that the duration of symptom relief varied significantly. A second, small pilot study of ten participants with Long COVID and ME found the treatment helped reduce post-exertional malaise and orthostatic intolerance. Still, as both studies were small and had many limitations, the authors of each study stated the need for further and larger studies on the procedure for Long COVID and ME.
🫁 An observational study is recruiting 40 people in Boston, Massachusetts to test for defects of air and blood flow in the lungs in people with Long COVID. The study will include questionnaires, pulmonary function tests, a special kind of x-ray called a low-dose CT scan, and a six-minute walk test. Contact: Bipin Malla, [email protected]
