Chronic Fatigue Syndrome

The primary objective of this study is to measure the concentration and the regional brain distribution of activated brain microglia/macrophages using the PET radiopharmaceutical \[F-18\]DPA-714 in individuals with chronic pain and fatigue suspected to be associated with neuroinflammation. The PET tracer \[F-18\]DPA-714 binds to the 18 kDa translocator protein (TSPO, also known as the peripheral benzodiazepine receptor) in the mitochondria of activated microglia/macrophages and provides a non-invasive measure of neuroinflammation. The primary objective of this study is to determine if pain and fatigue patients have higher levels of neuroinflammation than HC individuals as measured with \[F-18\]DPA-714-PET/MRI.

This study evaluates the effects of hyperbaric oxygen therapy (HBOT) in patients with mild to moderate CFS/ME. Participants will undergo 60 HBOT sessions over 3 months with a 3-month follow-up, including physical, cognitive, imaging, and laboratory assessments.

The purpose of this research is to evaluate the use of a voice-based tool in the diagnosis and management of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

Chronic fatigue is enhanced by adapted physical activity (APA) programs. Patients consulting on St Etienne hospital and suffering from fibromyalgia and long Covid benefit from a 4-6 week APA program, with 2 sessions per week. While most patients are improved by these exercise-training programs, for some the benefits remain very modest, and patients describe persistent fatigue. The literature unanimously describes the necessity of longer APA protocols (8-12 weeks, 2-3 sessions/week) for fatigue reduction in fibromyalgia and long Covid. However, it seems difficult to adhere to an optimal program as described in the literature for these fatigued patients. The investigators want to test a device that would both reduce fatigue and improve recovery between APA sessions, in order to gradually reach the recommendations for APA practice. Transcutaneous vagal nerve stimulation (tVNS) seems to be a promising approach. Thus, combining an APA intervention with a tVNS protocol could potentiate the expected and now well-known effect of exercise.

This will be a pilot multi-arm clinical trial investigating the feasibility of Lumbrokinase (LK) as an intervention in three clinical cohorts: * Long Covid (LC) * Post-treatment Lyme disease syndrome (PTLDS) * Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS)

Chronic fatigue syndrome/Myalgic encephalomyelitis (CFS/ME) can be a serious and disabling condition with a heavy symptom burden and low function. Work disability is common, and social life dramatically affected. CFS/ME is a challenging health problem as well as a societal problem. In recent years, a doubling of the number of patients with a CFS/ME diagnoses has been reported in Norway. The patient group represents a challenge for the health care system, the municipality, and the Norwegian Labour and Welfare Organization (NAV). According to new figures, the NAV pays 100 million Norwegian Kroner (NOK) each month in permanently incapacitated expenses for people with CFS/ME. Municipalities have expenses in form of care, rehabilitation and other measures. There is a lack of effective treatment for CFS/ME. Evidence-based knowledge is highly needed. If the 3-day course shows promising effects, this could have positive consequences for patients, relatives and health personnel, but also financially for the society and the municipality.

A prior open label study has shown that transcutaneous vagus nerve stimulation \[tVNS\] can improve the health of some patients with postacute sequelae of SARS-CoV-2 infection (PASC), severely affected enough to also fulfill criteria for myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS). The purpose of this study is to compare two sets of stimulus parameters to determine the one that best improves the health-related quality of life of these patients over a period of 6-weeks. Patients using their assigned device for at least 30 of the 42 possible opportunities will receive the best device for an additional 6-week period.

The aim of this multi-center, two-armed, randomized controlled trial is to assess the effect of a novel internet-based therapist-assisted treatment program "One step at a time" designed for the treatment of patients with moderate to severe functional somatic disorder (FSD). The trial will enroll 166 patients with FSD who will be randomized (1:1) to either the experimental condition (14 weeks' treatment with "One step at a time") or the active control condition ("GetStarted"), which is a non-guided internet-based treatment program for patients with FSD. The trial will include patients aged 18-60 years with an established single/oligo-organ or multi-organ FSD diagnosis, with a duration of minimum 6 months. The primary outcome measures will be based on self-reported physical health (SF-36 PPH) and treatment satisfaction (CGI-I). The trial will be considered effective if a higher proportion of patients in the experimental condition report a clinically significant outcome compared with patients in the active control condition at the 3-month follow-up after treatment.

The goal of this clinical trial is to learn if the OTC supplement, hydrogen water, works to treat the fatigue-related symptoms and functional limitations in adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). It will also examine if heart rate variability (HRV) can be used to predict who will benefit from the hydrogen water treatment. The main questions it aims to answer are: Does the OTC supplement, hydrogen water, work to reduce the fatigue-related symptoms and improve functioning in participants who have ME/CFS? Can HRV be used to predict who will benefit from treatment with hydrogen water?

To further characterize Long COVID-19 by collecting data from individuals who already own wearable devices or are provided with a wearable device along with basic and enhanced educational materials to determine if both can improve Long COVID-19 symptom management and post-exertional malaise.

Psychoneuromentalism Disorder is a disorder arising in the mind; that is related to the mental and emotional state of a person. It is the science of mental life. The body has a natural design to heal itself. This is a mental phenomena that cannot be explained, until now. Psychoneuromentalism Disorder is a new condition resulting from behavioral impairments, neurodiversity, and neurobehavioral dysfunctions that are related to the mental and emotional state of a participant.

The study seeks to delve into the firsthand experiences of patients diagnosed with chronic fatigue syndrome who partake in a separate clinical trial featuring a specific medical intervention. The primary emphasis will be on meticulously tracking the rates of trial completion and withdrawal among these individuals. The data collected from this study will help improve future outcomes for all chronic fatigue syndrome patients as well as those in under-represented demographic groups.

REBECCA-1 is an observational study. Clinical research is undergoing a revolutionary change. The use of electronic patient records (EHR), digital registers, smartphones etc will create "real-world data" (RWD) that provides great opportunities for advancing clinical research, but so far this opportunity has been little exploited. The REBECCA -1 study will observe and monitor fatigue in breast cancer survivors. Investigators will use self reported questionnaires (PROM-data), blood tests and objective regulations like the REBECCCA -1 smart watch that will register amount of steps every day, leaving the house, visiting friends, cafes etc. There will be three observational arms; 1.high fatigue, 2. low fatigue and 3. a healthy control arm. After the patients have finished their treatment, they will receive the REBECCA smart watch, a REBECCA app on the smart phone and a REBECCA plus device on their computer, The next offend are also invited to report their evaluation through the same apps. The observational time will be 1 year and comparison between the subjective PROM data , the objective REBECCA watch and the biological samples will be obtained.
