Abstract
Multiple sclerosis (MS) is a demyelinating disease characterized by plaque formation and neuroinflammation. The plaques can present in various locations, causing a variety of clinical symptoms in patients with MS. Coronavirus disease-2019 (COVID-19) is also associated with systemic inflammation and a cytokine storm which can cause plaque formation in several areas of the brain. These concurring events could exacerbate the disease burden of MS. We review the neuro-invasive properties of SARS-CoV-2 and the possible pathways for the entry of the virus into the central nervous system (CNS). Complications due to this viral infection are similar to those occurring in patients with MS. Conditions related to MS which make patients more susceptible to viral infection include inflammatory status, blood-brain barrier (BBB) permeability, function of CNS cells, and plaque formation. There are also psychoneurological and mood disorders associated with both MS and COVID-19 infections. Finally, we discuss the effects of exercise on peripheral and central inflammation, BBB integrity, glia and neural cells, and remyelination. We conclude that moderate exercise training prior or after infection with SARS-CoV-2 can produce health benefits in patients with MS patients, including reduced mortality and improved physical and mental health of patients with MS.

BMC psychiatry. 2022;(1):310
Abstract
BACKGROUND The COVID-19 pandemic had a profound psychological influence on everyone in society, and the impact it had on students, particularly medical students, cannot be underestimated. The main purpose of this study is to (1) determine the prevalence of mental disorders among medical students and their associated factors, and (2) examine the effectiveness of cognitive behavior therapy on mental health problems among medical students. METHODS Between March and May 2021, we conducted a randomized controlled study on two phases among medical students at An-Najah National University. Data were collected using an online questionnaire and the Arabic version of the 12-item General Health Questionnaire (GHQ-12). We also used the MEDAS tool to assess their Mediterranean Diet (MD) adherence. In the second phase, sixty-six students were recruited and assigned randomly to control and intervention groups. Intervention impact was assessed using 12-item General Health Questionnaire at two-time points; baseline, and 8 weeks post-intervention. The interventional model used was cognitive behavioral therapy, and the control group received no treatment. RESULTS A total of 329 students were included in the analysis of the first phase of the study. Approximately 28% of students had mental health problems. We found a significant relationship between good mental health status with a higher level of physical activity level, longer sleeping hours, and shorter entertainment time (p < 0.05). In the second phase of the study, a total of 91 students were included. Overall, using the CBT program showed a significant improvement in the outcome measures. At 8 weeks post-intervention, students had lower scores on total GHQ-12, depression, anxiety, and social dysfunction. CONCLUSION These findings propose that adequate attention must be paid to the mental health of medical students and that CBT programs can be used for the management of mental health problems among medical students.

Abstract
Racial and ethnic-related health disparities in the United States have been intensified by the greater burden of Coronavirus Disease 2019 (COVID-19) in racial and ethnic minority populations. Compared to non-Hispanic White individuals, non-Hispanic Black and Hispanic/Latinx individuals infected by COVID-19 are at greater risk for hospitalization, intensive care unit admission, and death. There are several factors that may contribute to disparities in COVID-19-related severity and outcomes in these minority populations, including the greater burden of cardiovascular and metabolic diseases as discussed in our companion review article. Social determinants of health are a critical, yet often overlooked, contributor to racial and ethnic-related health disparities in non-Hispanic Black and Hispanic/Latinx individuals relative to non-Hispanic White individuals. Thus, the purpose of this review is to focus on the essential role of social factors in contributing to health disparities in chronic diseases and COVID-19 outcomes in minority populations. Herein, we begin by focusing on structural racism as a social determinant of health at the societal level that contributes to health disparities through downstream social level (e.g., occupation and residential conditions) and individual level health behaviors (e.g., nutrition, physical activity, and sleep). Lastly, we conclude with a discussion of practical applications and recommendations for future research and public health efforts that seek to reduce health disparities and overall disease burden.

Abstract
The direct toxicity of cancer treatment threatens patients and survivors with an increased risk of cardiovascular disease or adverse functional changes with subsequent progression of cardiovascular complications. An accumulation of cardiovascular risk factors combined with an unhealthy lifestyle has recently become more common in cancer patients and survivors. It has been recommended to integrate a comprehensive cardiac rehabilitation model called cardio-oncology rehabilitation to mitigate cardiovascular risk. Nevertheless, cardiac rehabilitation interventions limit barriers in low utilization, further exacerbated by the restrictions associated with the COVID-19 pandemic. Therefore, it is essential to integrate alternative interventions such as telehealth, which can overcome several barriers. This literature review was designed as a framework for developing and evaluating telehealth interventions and mobile applications for comprehensive cardio-oncology rehabilitation. We identify knowledge gaps and propose strategies to facilitate the development and integration of cardio-oncology rehabilitation telehealth as an alternative approach to the standard of care for cancer patients and survivors. Despite the limited evidence, the pilot results from included studies support the feasibility and acceptability of telehealth and mobile technologies in cardio-oncology rehabilitation. This new area suggests that telehealth interventions are feasible and induce physiological and psychological benefits for cancer patients and survivors. There is an assumption that telehealth interventions and exercise may be an effective future alternative approach in supportive cancer care.

Abstract
Queries of youth orthopedic sports injuries from the U.S. National Electronic Surveillance System, a database from the Consumer Product Safety Commission, demonstrate decreased orthopedic injuries related to team sports during the COVID-19 pandemic, indicative of reduced sports participation. Multiple articles have shown that COVID-19 had a marked effect on the physical and psychological wellbeing of the youth. The lockdown resulted in a cessation in school attendance and sports activities, especially team sports. Though increased emphasis has been placed on children infected by COVID-19, less attention has been given to healthy children. Numerous articles discussed the physical and psychological benefits for the youth returning to physical activity and sports; however, few have addressed detraining and deconditioning concerns postpandemic. This article discusses a safe return to team sports for the youth experiencing physical and psychological changes related to the pandemic. Orthopedic injuries are anticipated to increase as restrictions are relaxed. A multidisciplinary team presents a review of common youth sports orthopedic injuries, a discussion of psychological issues youths have experienced during COVID and why sports participation is beneficial for youth, and a risk assessment for pain and limited range of motion for youth returning to sports. The intent of this article is to increase awareness of the physical and psychological changes experienced by youth due to their inability to participate in team sports during the pandemic. Family medicine and primary care providers need to recognize the increased risks for injury and proactively encourage the youth to return to sports in a safe manner.

Impact of COVID-19 on physical activity: A rapid review.
Park, AH, Zhong, S, Yang, H, Jeong, J, Lee, C
Journal of global health. 2022;:05003
Abstract
Background: Physical activity is a commonly prescribed medicine for people with conditions such as obesity and diabetes who are also at increased risk of being hospitalized or severely ill from COVID-19. However, many people are reporting challenges in engaging in a healthy dose of physical activity amid the pandemic. Objective: This rapid review synthesizes the current empirical evidence about the impacts of COVID-19 on people's outdoor physical activity and sedentary behavior while highlighting the role of community environments in promoting or hindering physical activity during the pandemic. Methods: Literature searches were conducted using keywords related to COVID-19: physical activity, mobility, and lifestyle behaviors. Eligibility criteria were peer-reviewed empirical and quantitative studies published in English, addressing COVID-19 and using physical activity and/or sedentary behavior as the study outcomes. Results: Out of 61 eligible studies, the majority (78.3%) were conducted in Asian and European countries, with only four (6.7%) being US studies. The results showed that COVID-19 was linked with significant decreases in mobility, walking, and physical activity, and increases in sedentary activity. A few studies also reported contradicting results including increased uses of parks/trails and increased recreational activity among certain groups of population. Conclusions: Evidence suggests an overall negative impact of COVID-19 on physical activity, with differential effects across different sub-populations. Significant knowledge gaps are also found in the roles of social and physical attributes that can promote physical activity during pandemics with reduced safety risks.

Abstract
BACKGROUND During the COVID-19 pandemic, compulsory masks became an integral part of outdoor sports such as jogging in crowded areas (e.g. city parks) as well as indoor sports in gyms and sports centers. This study, therefore, aimed to investigate the effects of medical face masks on performance and cardiorespiratory parameters in athletes. METHODS In a randomized, cross-over design, 16 well-trained athletes (age 27 ± 7 years, peak oxygen consumption 56.2 ± 5.6 ml kg-1 min-1, maximum performance 5.1 ± 0.5 Watt kg-1) underwent three stepwise incremental exercise tests to exhaustion without mask (NM), with surgical mask (SM) and FFP2 mask (FFP2). Cardiorespiratory and metabolic responses were monitored by spiroergometry and blood lactate (BLa) testing throughout the tests. RESULTS There was a large effect of masks on performance with a significant reduction of maximum performance with SM (355 ± 41 Watt) and FFP2 (364 ± 43 Watt) compared to NM (377 ± 40 Watt), respectively (p < 0.001; ηp2 = 0.50). A large interaction effect with a reduction of both oxygen consumption (p < 0.001; ηp2 = 0.34) and minute ventilation (p < 0.001; ηp2 = 0.39) was observed. At the termination of the test with SM 11 of 16 subjects reported acute dyspnea from the suction of the wet and deformed mask. No difference in performance was observed at the individual anaerobic threshold (p = 0.90). CONCLUSION Both SM and to a lesser extent FFP2 were associated with reduced maximum performance, minute ventilation, and oxygen consumption. For strenuous anaerobic exercise, an FFP2 mask may be preferred over an SM.

Obesity and Leptin Resistance in the Regulation of the Type I Interferon Early Response and the Increased Risk for Severe COVID-19.
Muskiet, FAJ, Carrera-Bastos, P, Pruimboom, L, Lucia, A, Furman, D
Nutrients. 2022;(7)
Abstract
Obesity, and obesity-associated conditions such as hypertension, chronic kidney disease, type 2 diabetes, and cardiovascular disease, are important risk factors for severe Coronavirus disease-2019 (COVID-19). The common denominator is metaflammation, a portmanteau of metabolism and inflammation, which is characterized by chronically elevated levels of leptin and pro-inflammatory cytokines. These induce the "Suppressor Of Cytokine Signaling 1 and 3" (SOCS1/3), which deactivates the leptin receptor and also other SOCS1/3 sensitive cytokine receptors in immune cells, impairing the type I and III interferon early responses. By also upregulating SOCS1/3, Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV)-2 adds a significant boost to this. The ensuing consequence is a delayed but over-reactive immune response, characterized by high-grade inflammation (e.g., cytokine storm), endothelial damage, and hypercoagulation, thus leading to severe COVID-19. Superimposing an acute disturbance, such as a SARS-CoV-2 infection, on metaflammation severely tests resilience. In the long run, metaflammation causes the "typical western" conditions associated with metabolic syndrome. Severe COVID-19 and other serious infectious diseases can be added to the list of its short-term consequences. Therefore, preventive measures should include not only vaccination and the well-established actions intended to avoid infection, but also dietary and lifestyle interventions aimed at improving body composition and preventing or reversing metaflammation.

Outcome of survivors of COVID-19 in the intermediate phase of recovery: A case report.
Fourie, M, van Aswegen, H
The South African journal of physiotherapy. 2022;(1):1751
Abstract
Introduction: Coronavirus disease 2019 (COVID-19) is a viral respiratory disease and is associated with significant morbidity in the intermediate and chronic phases of recovery from the disease. The health benefits of respiratory and extremity muscle strengthening exercise therapy are well-described for those with cardiac failure and interstitial lung disease and are suggested to improve functional ability for patients recovering from COVID-19. The aim of this case report is to share the effects of standard physiotherapy management on exercise endurance, respiratory function and return to work, implemented for patients with COVID-19 in the intermediate phase of their recovery. Patient presentation: Two cases of COVID-19 were admitted to a private healthcare facility in Johannesburg. They presented with shortness of breath and decreased endurance. One had COVID-19 myocarditis and the other chronic post-COVID-19 organising pneumonia with pulmonary fibrosis. Management and outcome: Both patients were admitted to ICU, provided oxygen therapy and supportive care as well as physiotherapy management in hospital and after hospital discharge. Physiotherapy management included inspiratory muscle training therapy, and cardiovascular and resistance exercise therapy. Improvements in peak expiratory flow rate and six-minute walk distance were observed for both cases at 6- and 7-months follow-up, respectively. Conclusion: Our case report illustrates the value of ongoing physiotherapy management, utilising progressive exercise therapy prescription, to aid the return to optimal functioning for survivors of COVID-19 in the intermediate phase of their recovery.

The Current Status of Research on High-Density Lipoproteins (HDL): A Paradigm Shift from HDL Quantity to HDL Quality and HDL Functionality.
Cho, KH
International journal of molecular sciences. 2022;(7)
Abstract
The quantity of high-density lipoproteins (HDL) is represented as the serum HDL-C concentration (mg/dL), while the HDL quality manifests as the diverse features of protein and lipid content, extent of oxidation, and extent of glycation. The HDL functionality represents several performance metrics of HDL, such as antioxidant, anti-inflammatory, and cholesterol efflux activities. The quantity and quality of HDL can change during one's lifetime, depending on infection, disease, and lifestyle, such as dietary habits, exercise, and smoking. The quantity of HDL can change according to age and gender, such as puberty, middle-aged symptoms, climacteric, and the menopause. HDL-C can decrease during disease states, such as acute infection, chronic inflammation, and autoimmune disease, while it can be increased by regular aerobic exercise and healthy food consumption. Generally, high HDL-C at the normal level is associated with good HDL quality and functionality. Nevertheless, high HDL quantity is not always accompanied by good HDL quality or functionality. The HDL quality concerns the morphology of the HDL, such as particle size, shape, and number. The HDL quality also depends on the composition of the HDL, such as apolipoproteins (apoA-I, apoA-II, apoC-III, serum amyloid A, and α-synuclein), cholesterol, and triglyceride. The HDL quality is also associated with the extent of HDL modification, such as glycation and oxidation, resulting in the multimerization of apoA-I, and the aggregation leads to amyloidogenesis. The HDL quality frequently determines the HDL functionality, which depends on the attached antioxidant enzyme activity, such as the paraoxonase and cholesterol efflux activity. Conventional HDL functionality is regression, the removal of cholesterol from atherosclerotic lesions, and the removal of oxidized species in low-density lipoproteins (LDL). Recently, HDL functionality was reported to expand the removal of β-amyloid plaque and inhibit α-synuclein aggregation in the brain to attenuate Alzheimer's disease and Parkinson's disease, respectively. More recently, HDL functionality has been associated with the susceptibility and recovery ability of coronavirus disease 2019 (COVID-19) by inhibiting the activity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The appearance of dysfunctional HDL is frequently associated with many acute infectious diseases and chronic aging-related diseases. An HDL can be a suitable biomarker to diagnose many diseases and their progression by monitoring the changes in its quantity and quality in terms of the antioxidant and anti-inflammatory abilities. An HDL can be a protein drug used for the removal of plaque and as a delivery vehicle for non-soluble drugs and genes. A dysfunctional HDL has poor HDL quality, such as a lower apoA-I content, lower antioxidant ability, smaller size, and ambiguous shape. The current review analyzes the recent advances in HDL quantity, quality, and functionality, depending on the health and disease state during one's lifetime.
