Article Abstract
Topic Importance: Postacute sequelae of SARS-CoV-2 (PASC) is a long-term consequence of acute infection from COVID-19. Clinical overlap between PASC and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) has been observed, with shared symptoms including intractable fatigue, postexertional malaise, and orthostatic intolerance. The mechanistic underpinnings of such symptoms are poorly understood.
Review Findings: Early studies suggest deconditioning as the primary explanation for exertional intolerance in PASC. Cardiopulmonary exercise testing reveals perturbations related to systemic blood flow and ventilatory control associated with acute exercise intolerance in PASC, which are not typical of simple detraining. Hemodynamic and gas exchange derangements in PASC have substantial overlap with those observed with ME/CFS, suggestive of shared mechanisms.
Summary: This review illustrates exercise pathophysiologic commonalities between PASC and ME/CFS that will help guide future diagnostics and treatment.
Background: Myalgic encephalomyelitis (ME) is associated with long COVID and also untoward sequelae after anti-coronavirus vaccination. Recently, oral minocycline therapy has been reported to ameliorate symptoms in patients with ME, particularly at the initial stage of the disease.
Methods: Oral minocycline (100 mg × 2 on the first day, followed by 100 mg/day for 41 days) was administered to 55 patients with ME that emerged during the "Corona era," including 19 patients with long COVID and 5 patients diagnosed with untoward sequalae following coronavirus vaccination.
Background And Objectives: Polycystic ovary syndrome (PCOS) is a prevalent female reproductive and metabolic disorder. Among patients with chronic conditions, an increasing number have approached complementary and alternative medicine (CAM) to cope with their disease. This study aimed to assess the use of CAM among females with PCOS in Jordan.
Introduction: Fibromyalgia (FM) and chronic fatigue syndrome (CFS) are complex central sensitization syndromes that represent an important public health problem. Low cardiorespiratory fitness and muscle function with habitual intolerance to efforts are common characteristics of FM and CFS. This study aimed to examine the effect of a brief multicomponent intervention based on physical activity (PA), nutrition, and chronobiology on movement behaviors (PA, sedentary and sleep time), muscle strength, and cardiorespiratory capacity.
Introduction: The harmful alga Karenia brevis (K. brevis) releases brevetoxins (PbTx) that cause respiratory and neurological symptoms. The apolipoprotein E (APOE) ε4 allele has been linked to poor neurological outcomes after exposure to environmental toxicants.
Background: Little is known about how symptoms or symptom clusters of Post-COVID Conditions (PCC) impact an individual's return to pre-COVID health.
Methods: We used four state-level COVID-19 case reporting systems and patient-reported survey data to identify patients with PCC and associations with an individual's return to pre-COVID health after laboratory-confirmed SARS-CoV-2 infection. Participants had a positive SARS-CoV-2 test between March-December 2020.
