Glioblastoma (GBM) is an aggressive, common brain cancer known to disrupt redox biology, affecting behavior and DNA integrity. Past research remains inconclusive. To further understand this, an investigation was conducted on physical training’s effects on behavior, redox balance, and genomic stability in GBMA models. Forty-seven male C57BL/6J mice, 60 days old, were divided into GBM and sham groups (n = 15, n = 10, respectively), which were further subdivided into trained (Str, Gtr; n = 10, n = 12) and untrained (Sut, Gut; n = 10, n = 15) subsets. The trained mice performed moderate aerobic exercises on a treadmill five to six times a week for a month while untrained mice remained in their enclosures. Behavior was evaluated using open-field and rotarod tests. Post training, the mice were euthanized and brain, liver, bone marrow, and blood samples were analyzed for redox and genomic instability markers. The results indicated increased latency values in the trained GBM (Gtr) group, suggesting a beneficial impact of exercise. Elevated reactive oxygen species in the parietal tissue of untrained GBM mice (Gut) were reduced post training. Moreover, Gtr mice exhibited lower tail intensity, indicating less genomic instability. Thus, exercise could serve as a promising supplemental GBM treatment, modulating redox parameters and reducing genomic instability.

The sequelae of coronavirus disease-2019 (COVID-19) are another socio-economic problem of the pandemic. Fatigue and dyspnea are the most prevalent symptoms. It is not known whether exercise can be used to treat long COVID-19. This study aimed to investigate the effects of an 8-week face-to-face rehabilitation program on COVID-19 compared to a remote monitoring group. A total of 37 participants (24.3% hospitalized) were assessed before and after rehabilitation (n = 22; 40.8 ± 10.0 years) or remote monitoring (n = 15; 45.4 ± 10.5 years). The participants were allocated according to their preferences. Both groups showed improved fatigue and exercise capacity (Incremental Shuttle Walk Test). Participants in the face-to-face rehabilitation group showed improved dyspnea (Pulmonary Functional Status and Dyspnea Questionnaire), anxiety (Hospital Anxiety and Depression Scale), attention, and short-term memory (d2-R and Rey's Auditory-Verbal Learning Test). Of the main sequelae, fatigue improves naturally, whereas dyspnea requires rehabilitation. Our results demonstrated the benefits of exercise for COVID-19 sequelae.

Coronavirus 2 is responsible for Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2), and the main sequela is persistent fatigue. Post-viral fatigue is common and affects patients with mild, asymptomatic coronavirus disease-2019 (COVID-19). However, the exact mechanisms involved in developing post-COVID-19 fatigue remain unclear. Furthermore, physical and cognitive impairments in these individuals have been widely described. Therefore, this review aims to summarize and propose tools from a multifaceted perspective to assess COVID-19 infection. Herein, we point out the instruments that can be used to assess fatigue in long-term COVID-19: fatigue in a subjective manner or fatigability in an objective manner. For physical and mental fatigue, structured questionnaires were used to assess perceived symptoms, and physical and cognitive performance assessment tests were used to measure fatigability using reduced performance.
