Highlights Diminished muscle oxygen saturation is likely to be closely correlated with COVID-19 disease severity. • Diminished muscle oxygen saturation is likely to be predictive of COVID-19 disease progression. • Near-Infrared Spectroscopy (NIRS) can augment existing markers tracking disease...

I've recently been having a better look at reports of my garmin vivosmart watch, specifically the ones during sleep as I've only fairly recently been wearing it overnight. I found that it also regularly monitors spO2 during the night and the readings are a bit concerning as my levels drop...

My doctor wants me to try “oxygen therapy” after seeing it on a “treatment list” by an “expert doctor” in ME/CFS. I’m aware there probably isn’t any evidence behind this, and am slightly baffled why I was prescribed it given my oxygen levels are normal. What I’m wondering is, could this make...

Red Blood Cell Adenylate Energetics Is Related to Endothelial and Microvascular Function in Long COVID Romanowska-Kocejko, Marzena; Jędrzejewska, Agata; Braczko, Alicja; Stawarska, Klaudia; Król, Oliwia; Frańczak, Marika; Harasim, Gabriela; Smoleński, Ryszard T.; Hellmann, Marcin; Kutryb-Zając...

Impaired oxygen delivery to muscle in chronic fatigue syndrome McCully, Kevin K.; Natelson, Benjamin H. The purpose of this study was to determine if chronic fatigue syndrome (CFS) is associated with reduced oxygen delivery to muscles. Patients with CFS according to CDC (Center for Disease...

Introduction Monitoring muscle metabolic activity via blood lactate is a useful tool for understanding the physiological response to a given exercise intensity. Recent indications suggest that skeletal muscle oxygen saturation (SmO2), an index of the balance between local O2 supply and demand...

COVID-19 disease, caused by the severe acute respiratory syndrome virus 2 (SARS-CoV-2), induces a broad spectrum of clinical symptoms ranging from asymptomatic cases to fatal outcomes. About 10–35% of all COVID-19 patients, even those with mild COVID-19 symptoms, continue to show symptoms...

Mitochondria and oxygen homeostasis Mateus P. Mori; Rozhin Penjweini; Jay R. Knutson; Ping-yuan Wang; Paul M. Hwang Molecular oxygen possesses a dual nature due to its highly reactive free radical property: it is capable of oxidizing metabolic substrates to generate cellular energy, but can...

The effect of hyperbaric oxygen therapy on myocardial function in post-COVID-19 syndrome patients: a randomized controlled trial Leitman, Marina; Fuchs, Shmuel; Tyomkin, Vladimir; Hadanny, Amir; Zilberman-Itskovich, Shani; Efrati, Shai Post-COVID-19 condition refers to a range of persisting...

Abstract Post-COVID-19 condition refers to a range of persisting physical, neurocognitive, and neuropsychological symptoms after SARS-CoV-2 infection. The mechanism can be related to brain tissue pathology caused by virus invasion or indirectly by neuroinflammation and hypercoagulability. This...

Decreases in maximal oxygen uptake following long-duration spaceflight: Role of convective and diffusive O2 transport mechanisms C. J. Ade, R. M. Broxterman, A. D. Moore, and T. J. Barstow Abstract We have previously predicted that the decrease in maximal oxygen uptake (V̇o2max) that...

Male vs. Female Differences in Responding to Oxygen–Ozone Autohemotherapy (O2-O3-AHT) in Patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Abstract (1) Background: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a syndrome that has fatigue as its major...

Patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Greatly Improved Fatigue Symptoms When Treated with Oxygen-Ozone Autohemotherapy Abstract (1) Background: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a chronic syndrome characterized by fatigue as its...

Abstract Background Long COVID is a common occurrence following COVID-19 infection. The most common symptom reported is fatigue. Limited interventional treatment options exist. We report the first evaluation of hyperbaric oxygen therapy (HBOT) for long COVID treatment. Methods A total of 10...

OBJECTIVE: Post-acute sequelae of SARS-CoV2 infection (PASC) are a novel terminology used to describe post-COVID persistent symptoms, mimicking somehow the previously described chronic fatigue syndrome (CFS). In this manuscript, we evaluated a therapeutical approach to address PASC-derived...

Medscape Medical News: Breathing Enriched Oxygen May Improve Major Depression

Not strictly health news, but an interesting development in understanding the role of mitochondria. "The myxozoan cells retain structures deemed mitochondrion-related organelles, but have lost genes related to aerobic respiration and mitochondrial genome replication. Our discovery shows that...

Not directly ME related, but an interesting article on nrk.no today about a new intervention that could help some people with cluster headaches (the really horrible ones that show up every single night and make people want to commit suicide). Apparently a significant portion of those patients...
