"I think I saw four or five different specialists because the symptoms that I was having, they were across multiple [body] systems. All the specialists said 'this is ME' and we don't want it to be that because there's nothing out there for it." #MECFS #LongCovid www.bbc.com/sport/athlet...

bbc.comBeth Dobbin: British Olympic sprinter in bed for 22 hours a day after ME diagnosisBeth Dobbin ran for Great Britain at the Tokyo Olympics in 2021. Five years on, she is largely bedbound after being diagnosed with ME, a devastating illness for which there is no cure.

"…18% of patients with coronary function testing-confirmed ANOCA meeting diagnostic criteria for #MECFS. Invasive cardiopulmonary exercise testing (iCPET) in patients with [both] reveals a primary peripheral, not cardiac, limitation to exercise." #Cardiology journals.physiology.org/doi/10.1152/...

journals.physiology.orgHemodynamic Phenotyping in ME/CFS and ANOCA: Complementary Insights from Coronary Function Testing and Invasive Cardiopulmonary Exercise Testing | American Journal of Physiology-Heart and Circulatory Physiology | American Physiological SocietyThis single-center cohort study sought to evaluate the association between Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Angina with Non-Obstructive Coronary Arteries (ANOCA), by determining the observed frequency of ME/CFS among patients with ANOCA diagnosed by coronary function testing (CFT). Additionally, we performed an exploratory analysis of the diagnostic utility of invasive cardiopulmonary exercise testing (iCPET) in ME/CFS patients with CFT-confirmed ANOCA, with the aim of identifying the predominant physiological mechanism responsible for exertional limitation in this population. Systematic medical record review of 261 patients with CFT-confirmed ANOCA was performed using standardized diagnostic criteria to identify concurrent ME/CFS diagnosis. ME/CFS was identified in 47 patients, representing an observed frequency of 18%. The only statistically significant difference between ANOCA patients with and without ME/CFS was a higher frequency of connective tissue disease in the ME/CFS group (p = 0.0221). In a separate cohort of 27 patients with ME/CFS who underwent iCPET, 24 patients (89%) had CFT-confirmed ANOCA. The diagnosis of ANOCA by CFT prompted a change in medical management in 81% of patients in this cohort. iCPET revealed a primary peripheral limitation to exercise, characterized by impaired peak systemic oxygen extraction despite normal peak oxygen delivery. This study demonstrates a clinically significant association between ME/CFS and ANOCA. These findings underscore the clinical value of CFT in patients with ME/CFS and exertional chest pain and highlight iCPET as a complementary tool for hemodynamic phenotyping in this population. Prospective studies incorporating simultaneous CFT and iCPET with molecular phenotyping are warranted.

"As mitochondrial and endothelial dysfunction appear prominent in both long COVID and ME/CFS, with clear implications on oxygen extraction, future studies should aim to investigate the viability of improving patient mitochondrial and/or endothelial health to reduce patient burden."

This is very welcome news. It will extend the initial findings from DecodeME at the University of Edinburgh, led by Prof Chris Ponting @cgatist.bsky.social #MECFS #LongCovid

Great news from the UK🍾 £4.75 million to do whole-genome sequencing on 6000 DecodeME samples www.thetimes.com/uk/healthcar... (paywall) Unfortunately it's not enough to analyse the full sample People can find out more about SequenceME & donate here megenetics.org.uk/our-projects... #MEcfs #PwME

1) 1) Interesting interview of Dr. Audrey Ryback by David Tuller. Her recent study showed that there are likely two age peaks for when people get ME/CFS. It helps to characterise ME/CFS as a unique clinical entity.

SARS-CoV-2 (COVID-19) is anything but a common cold. Each infection can cause severe illness and even death in children at rates +++ higher than the common cold. It triggers long-covid (now the most common chronic illness in children) and other cobditions like diabetes. Not the common cold.

Exciting to read about some of the expensive ME/CFS & long Covid research planned in Germany (using some of€500 million budget) including that using long-term samples which allow comparisons of samples before and after developing the conditions www.helmholtz.de/en/newsroom/... #LongCovid #MEcfs

Huh. It's almost as if betting the world on a game of "let's pretend" between a bunch of pseudoscientific cosplayers wasn't a great public health strategy for dealing with COVID after all. 🤔 It must be nothing though. I'm sure we could trust management-class MDs to tell us if they got it wrong...

Nobody buries their successes. Presumably IPC is still working on fabricating that "very careful narrative" that will let them back away from killing people without admitting they're currently killing people or facing accountability for all the people they've already killed. This narrative:

"we identified that PC(O-38:4) had significantly reduced levels in ME/CFS LCLs and was almost entirely discriminative of ME/CFS status" #MECFS generated lymphoblastoid cell lines "show accumulation of lipids, skewed lipid profiles and altered activity of related metabolic enzymes such as PTDSS1."

This blog post is a very accurate characterisation of the experience of living with #PostExertionalMalaise #PEM. Recommended reading for healthcare professionals who want to understand #MECFS and #LongCovid. You generally only see these patients when they're at their best — not in the aftermath.

Here’s a quote from my piece, Why I Can’t Just Meet You for Dinner, about post-exertional malaise. This is after work while I’m in the middle of a PEM crash. #PEM #MECFS #LongCovid #ChronicIllness #Disabled substack.com/home/post/p-...

I never met Alice Wong in person, but like so many great writers I felt like I knew her - and unlike many, when I emailed she emailed right back. ❤️ Peds neurologist @dianacejasmd.bsky.social has a beautiful essay in Wong's Disability Visibility collection - I recommend it to physicians. #neurosky

WTAF. This is an absolute travesty. Teen Vogue has consistently been a light in the dark and once again the corporate overlords just end it all.

Lex McMenamin (they/them)@lexmcmenamin.com

I was laid off from Teen Vogue today along with multiple other staffers, and today is my last day. certainly more to come from me when the dust has settled more, but to my knowledge, after today, there will be no politics staffers at Teen Vogue.
