UK ME/CFS Biomedical Partnership
Patient & Public Involvement (PPI) Steering Group Update
A workshop hosted by the Medical Research Council and National Institute for Health Research was held this week. Researchers, patients, supporters and funders met to assist in developing the research proposal including a Genome Wide Association Study (GWAS). Topics discussed included case definition, methodology and governance. A research proposal will be submitted in January. See survey on selection criteria below.

A Life Hidden – the First Year
Naomi Whittingham, who has had severe ME for many years, has this year started a blog with a series of thoughtful articles, including 'The Power Of Listening' originally written in 2016 for a training seminar for junior doctors; a series of 3 articles critiquing the BACME guidelines on severe ME; and several reflective articles on life with severe ME.

Cornell Research
''A Researcher's Duality: Plants, Biomedical'' by Jackie Swift
Article about Prof. Maureen Hanson, originally a plant biologist who researched gene expression in plants, but who switched to researching ME after her son was diagnosed. She is the founder and director of the Cornell Center for Enervating NeuroImmune Disease. Her research includes the immune system and extracellular vesicles, and how they change during exercise and PEM.

UK NHS Digital has confirmed, in a response to a question from the Grace Charity for ME, that ME is still listed under ICD-10 code G93.3 Postviral fatigue syndrome. ''Within the structure of ICD-10, the code G93.3 is indeed located in Chapter VI Diseases of the nervous system.''

Research news and talks
Dr Michael van Elzakker gave a talk in Boston entitled “Investigating ME/CFS at the intersection of the nervous and immune systems.”
He discussed some challenges and opportunities in using brain scans to study communication between the immune and nervous systems. He described two ongoing studies that seek to elucidate autonomic dysfunction and possible neuroinflammation in ME/CFS and also gave an update on the OMF-funded Harvard ME/CFS Collaboration.

Journal of Clinical Sleep Medicine
''Parasympathetic activity is reduced during slow-wave sleep, but not resting wakefulness, in patients with CFS'' by Fatt et al.
24 patients and 24 healthy controls tested during sleep with EEG and heart rate variability. Differences in sleep architecture were found. The abstract concludes 'Autonomic hypervigilance during the deeper, recuperative stages of sleep is associated with poor quality sleep and self-reported wellbeing.'

''Signs of Intracranial Hypertension, Hypermobility and Craniocervical Obstructions in patients with ME/CFS'' by Bragée et al.
In a study of patients from a Swedish tertiary clinic for severe ME sufferers, previous patients were recalled for testing for hypermobility, intracranial hypertension and obstruction in the foramen magnum by cerebellar tonsils. Higher rates for each of these were found than reported in the general population, though there was no control group, and this patient group may not be representative of the ME population.

Review article ''Understanding neuromuscular disorders in CFS'' by Jammes et al.
The authors look at possible mechanisms of central and peripheral fatigue and hypothesise that heat shock proteins may be significant.

Pharmacovigilance and Pharmacoepidemiology
''The Effect of Curcumin in Patients with CFS/ME Disparate Responses in Different Disease Severities'' by van Campen et al.
ME patients (Fukuda diagnosis) given curcumin capsules for 8 weeks in an open label study with subjective outcome measures and high drop out rate, found little effect.

Journal of the International Neuropsychological Society
"Prevalence and Treatment of CFS/ME and Co-morbid Severe Health Anxiety" by Daniels et al.
The research team of Jo Daniels reports that approximately 40% of the ME/CFS patients studied experienced significant levels of anxiety. Forum members, however, have raised concerns about the validity of the anxiety questionnaires used in this study.

"Is CFS related to a crash of the brain attention mechanism - Hypervigilance correlates with fatigue and pain scales among individuals with CFS" by Minani CM.
In this master thesis, Norwegian researcher Camilla Marylene Minani reports to have used a visual continuous performance task to study sustained arousal in a sample of 42 ME/CFS patients. Based on measurements of brain responses to stimuli during the task, the abstract claims that ME/CFS is associated with hyper-vigilance, delayed motor response and reduced error-detection resources.
