Blood-Brain Barrier Integrity and Immune Dynamics in Neuropsychiatric Sequelae of Post-SARS-CoV-2 Onset ME/CFS Versus Pre-Pandemic ME/CFS Patients
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex chronic illness impacting multiple body systems and characterized by activity-limiting fatigue and post exertional symptom exacerbation, affecting over 3.5 million adults in the US and as many as half of those with long COVID. The mechanisms behind the frequently profound cognitive impairments in MECFS are elusive; however, disruption of the integrity of the blood brain barrier (BBB) and immune cell migration into the brain are thought to contribute to neuroinflammation and related neuropsychiatric burden in MECFS. This project combines brain imaging, neuropsychiatric assessments, and blood-based measures of inflammation in pre-pandemic and post-pandemic individuals with MECFS to understand the role of BBB permeability and inflammation as contributors to key aspects of cognition and mood.

Assessment of N-Acetylcysteine as Therapy for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome
Chronic fatigue syndrome/myalgic encephalomyelitis (ME/CFS) is an unexplained multisymptom/multisystem disorder for which there are currently no validated treatments. The present exploratory clinical trial aims to advance our understand of the mechanisms of in situ GSH synthesis control through assessment of the response of brain GSH and plasma markers of oxidative stress to different doses of NAC in comparison to placebo, as a potential treatment for ME/CFS that would provide neuroprotection against oxidative stress by restoring cortical GSH reserves. If successful, this exploratory clinical trial would address a significant public health concern by shedding new light onto the mechanisms of action of NAC in brain GSH restoration, which could open a new avenue for the development of potentially effective treatments for a disorder, ME/CFS, that currently has none.

Assessment of Neuroinflammation in Central Inflammatory Disorders Using [F-18]DPA-714.
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.

A 3-day Course for CFS/ME
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.

tVNS in Long COVID-19
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.

Does a Technology Enabled Multi-disciplinary Team-based Care Model for the Management of Long COVID and Other Fatiguing Illnesses Improve Clinical Care of Patients and Represent a Sustainable Approach Within a Federally Qualified Health Center?
The primary objective of the present research is to determine the effectiveness of Family Health Center of San Diego's Long COVID and Fatiguing Illness Recovery Program (LC\&FIRP) on clinician- and patient-level outcomes. LC\&FIRP is comprised of a teleECHO program focused on multi-specialty case-consultation and peer-to-peer sharing of emerging best practices to support management of complex cases associated with Long COVID, Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), and other post-infectious fatiguing illnesses (PIFI). Our secondary objective is to determine the feasibility, acceptability, and sustainability of LC\&FIRP. Our findings should provide a fuller understanding of the potential impact of innovative technology enabled multi-disciplinary team-based care models in low-resource, community-based primary care settings.

Internet-based Treatment for Patients Suffering From Severe Functional Somatic Disorders
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.

Hydrogen Water Intervention With Heart Rate Variability as an Outcome Biomarker in ME/CFS
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?

A Longitudinal Study on Longstanding Complicated Fatigue
The purpose of the study is to investigate if there are common biopsychosocial vulnerability factors for developing and maintaining fatigue, regardless of the diagnosis. The investigators also believe that subgroups differ in terms of these factors. Participating patients with ME/CFS, burnout syndrome and post-covid fatigue complete a web form at inclusion and after 1, 2, 4, 6, 12, 18 and 24 months. There is no upper limit for the number of participants in the web survey. 150 participants are asked to submit blood samples at a local laboratory in connection with the questionnaires for analysis of inflammatory markers and one urine sample for analysis of nutritional markers. Two control groups are included, 150 patients with rheumatoid arthritis and 50 healthy individuals. The longitudinal design makes it possible to investigate how inflammatory markers, nutritional status, symptom burden, health related quality of life co-vary over time and how work ability and sick leave is affected.

Transcutaneous Vagus Nerve Stimulation as a Complementary Therapy to Exercise in Chronic Fatigue
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.

A Feasibility Study: Assessing Photobiomodulation in Myalgic Encephalomyelitis
There is no cure or approved treatments for ME. Several causes have been implicated in ME, including poor mitochondrial function. Mitochondria are the powerhouse of cells, producing energy. Therefore, loss of mitochondrial function and reduced energy production could be an explanation for the debilitating chronic fatigue that defines ME. The primary site of red light absorption in cells is the mitochondria. Mitochondrial red light absorption can boost energy production. Light therapy is already FDA approved for the treatment of acne, muscle and joint pain, arthritis, blood circulation issues and hair loss. This is the first study to trial the use of red light therapy in ME and results will help us understand if the use of red light therapy is accepted by ME patients. In past clinical trials the monitoring of symptom reduction/increase in ME patients was mainly done using symptom questionnaires. These questionnaires have not been specifically developed for ME symptoms and therefore the reliability of results is poor. This study will be assessing the use of a new symptom questionnaire developed specifically for ME and will also be trialling the use of other tools to measure symptom reduction/increase. In addition, this study will also trial the use of Mantal, an online remote research management portal. This is to improve accessibility of ME patients to research participation. Each ME participants involvement in the study should take approximately 7 weeks. Involvement is split into four phases: 1) baseline, 2) intervention, 3) follow-up and 4) feedback. Baseline assessments: * Week one: complete a 27-item questionnaire on functional capacity (FUNCAP27) and online cognitive function tests * Week two: participants are posted an activity monitor which they are to wear for seven days. Participants will complete a sleep diary (consensus sleep diary version E) for seven days Intervention: \- Participants are posted the red lamp to use in their own homes during weeks three and four. Participants use the red lamp for two minutes, daily, each morning for a total of 14 days. Follow-up: * Weeks five and six * Repeating the baseline assessments Feedback: \- Participants are asked to complete an online questionnaire during week seven.

Monitoring of Chronic Conditions in Breast Cancer
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.
