    A nanoelectronics-blood-based diagnostic biomarker for ME/CFS (2019) Esfandyarpour, Davis et al

    Sorry come I had assumed you had seen that’s because of your question about the geometry. As someone without any experience of PBMC is suspended in plasma, I had assumed that there might be some local forces attracting the sounds to be electrode. But also, I had assumed that some of the cells...

    A nanoelectronics-blood-based diagnostic biomarker for ME/CFS (2019) Esfandyarpour, Davis et al

    "What" is a lot easier to answer than "why". They produced "simplified blood" of each patient made up of PBMCs resuspended in plasma, 200 cells per microlitre. A sample of this was added to the Nanoneedle chip and they then measured in impedance. Impedance is defined as the ratio of applied...

    A nanoelectronics-blood-based diagnostic biomarker for ME/CFS (2019) Esfandyarpour, Davis et al

    This is the key issue, particularly given the frequent claim that this shows ME/CFS is not "all in the mind" (I really dislike that phrase because it denigrates mental health problems). Depression probably has a stronger immune signal than ME/CFS. Michael VanElzakker has pointed out that you...

    A nanoelectronics-blood-based diagnostic biomarker for ME/CFS (2019) Esfandyarpour, Davis et al

    In the discussion, the authors say "According to our experimental results, ME/CFS blood cells display a unique characteristic in the impedance pattern…" Yes, as they go on to say, it is significantly different from healthy controls. But no one has a problem distinguishing ME patients from...

    A nanoelectronics-blood-based diagnostic biomarker for ME/CFS (2019) Esfandyarpour, Davis et al

    Have had a quick read through The paper and thought I'd place here before I went to bed. They do claim that the finding is unique to ME/CFS. So those comparisons with sick controls are essential. As I think everyone has pointed out, bigger samples are also needed. Though the Stanford piece...

    Blog: 'Summary so far of "Something in the blood"' by Simon McGrath

    Both groups use the same method, the Seahorse analyser. as Lisa says, the findings are consistent because the most obvious exclamation for the load oxygen consumption in ME/CFS plasma is increased mitochondrial activity, the same as Fluge found.

    Blog: 'Summary so far of "Something in the blood"' by Simon McGrath

    Blog preview Something in the blood It is remarkable that four independent groups have now found that a factor in the blood can affect cell metabolism/mitochondria in ME/CFS and transfer the effect to healthy cells. Here is a summary of the provisional findings. Fluge & Mella The first to...

    Long Term Follow up of Young People With Chronic Fatigue Syndrome Attending a Pediatric Outpatient Service, 2019, Rowe

    I have been in touch with Dr Kathy Rowe, the sole author of the study, who was really helpful in providing additional information. Several points she mentioned are worth sharing (with permission): 1. To count as recovered, patients both had to say there were recovered and to specify how long...

    Long Term Follow up of Young People With Chronic Fatigue Syndrome Attending a Pediatric Outpatient Service, 2019, Rowe

    Unfortunately, my migraines are getting ever worse and I probably won't be able to return to this thread after this post. Yes, the distinction between remission and recovery is very important. In this case, though, I think most of the results will cover recovery. If you look at the group with...

    Long Term Follow up of Young People With Chronic Fatigue Syndrome Attending a Pediatric Outpatient Service, 2019, Rowe

    The Brown, Bell and Jason paper from 2012 is important in relation to the new study as it aims to see if patients who said they were recovered really were or not. They did this by checking if symptoms and function scores were consistent with recovery, and found "that over time many individuals...

    Evidence of widespread metabolite abnormalities in ME/CFS: assessment with whole-brain magnetic resonance spectroscopy (2019) Younger et al.

    Brief commentary An interesting approach to studying "neuroinflammation“ yields only one robust finding. Jarred Younger is looking for evidence that would support hypothesis that ME/CFS is driven by low-grade immune activation in the brain. It's an interesting approach using widely-available...

    Estimating Prevalence, Demographics and Costs of ME/CFS Using Large Scale Medical Claims Data and Machine Learning, 2018, Valdez, Proskauer et al

    I read this for another purpose and thought I'd post my comments here. It makes sense to explore the value of the huge insurance claims database, with thousands of cases of "CFS" and "ME", But both the symptoms/factors selected by machine learning and the demographics look implausible for...

    Persistent fatigue induced by interferon-alpha: A novel, inflammation-based, proxy model of Chronic Fatigue Syndrome, 2018, Pariante et al

    Here is the key quote from Michael Sharpe, and he has it wrong: The good thing about a prospective study, the design here, is that you look what happens first and then what happens afterwards. Since the immune activation happens first and the fatigue a long time later that’s good evidence that...

    Increased risk of chronic fatigue syndrome following burn injuries, 2018, Tsai et al

    The instants rate of 1.6 cases per thousand = 0 .16% new cases per year. That is implausibly hi given that prevalence (two cases) is around 0.2%. So I would agree that this is not measuring ME/CFS, particularly as they didn’t do a proper diagnosis. There I would be extremely interested to see...

    Erythrocyte Deformability As a Potential Biomarker for Chronic Fatigue Syndrome, Davis et al (2018)

    Perfectly put. I am concerned about this claim: it would explain how they get such a small P value from the tiny sample, but that P value does not tell you how likely the finding is to hold up in the wider patient population. On the letter is what we need to know. There is another issue. IIRC...
