The vital role of exercise and nutrition in COVID-19 rehabilitation: synergizing strength.

Since the outset of the COVID-19 pandemic, the global healthcare community has faced the challenge of understanding and addressing the ongoing and multi-faceted SARS-CoV-2 infection outcomes. As millions of individuals worldwide continue to navigate the complexities of post-hospitalization recovery, reinfection rates, and the increasing prevalence of Long-COVID symptoms, comprehensive COVID-19 rehabilitation strategies are greatly needed. Previous studies have highlighted the potential synergy between exercise and nutrition, suggesting that their integration into patient rehabilitation programs may yield improved clinical outcomes for survivors of COVID-19. Our group aimed to consolidate existing knowledge following the implementation of patient, intervention, comparison, and outcome (PICO) search strategies on the distinct and combined impacts of exercise and nutrition interventions in facilitating the recovery of COVID-19 patients following hospitalization, with a specific focus on their implications for both public health and clinical practice. The incorporation of targeted nutritional strategies alongside exercise-based programs may expedite patient recovery, ultimately promoting independence in performing activities of daily living (ADLs). Nonetheless, an imperative for expanded scientific inquiry remains, particularly in the realm of combined interventions. This mini-review underscores the compelling prospects offered by an amalgamated approach, advocating for the seamless integration of exercise and nutrition as integral components of post-hospitalization COVID-19 rehabilitation. The pursuit of a comprehensive understanding of the synergistic effects and effectiveness of exercise and nutrition stands as a crucial objective in advancing patient care and refining recovery strategies in the wake of this enduring global health crisis.

Early COVID-19 Interventions Failed to Replicate 1918 St. Louis vs. Philadelphia Outcomes in the United States.

The Coronavirus disease 2019 (COVID-19) pandemic has elicited an abrupt pause in the United States in multiple sectors of commerce and social activity. As the US faces this health crisis, the magnitude and rigor of their initial public health response was unprecedented. As a response, the entire nation shutdown at the state-level for the duration of a ~1-3 months. These public health interventions, however, were not arbitrarily decided, but rather, implemented as a result of evidence-based practices. These practices were a result of lessons learned during the 1918 influenza pandemic and the city-level non-pharmaceutical interventions (NPIs) taken across the US. During the 1918 pandemic, two model cities, St. Louis, MO, and Philadelphia, PA, carried out two different approaches to address the spreading disease, which resulted in two distinctly different outcomes. Our group has evaluated the state-level public health response adopted by states across the US, with a focus on New York, California, Florida, and Texas, and compared the effectiveness of reducing the spread of COVID-19. Our assessments show that while the states mentioned above benefited from the implementations of early preventative measures, they inadequately replicated the desired outcomes observed in St. Louis during the 1918 crisis. Our study indicates that there are other factors, including health disparities that may influence the effectiveness of public health interventions applied. Identifying more specific health determinants may help implement targeted interventions aimed at preventing the spread of COVID-19 and improving health equity.

Biopsychosocial and Spiritual Implications of Patients With COVID-19 Dying in Isolation.

Critically ill patients with the Coronavirus disease 2019 (COVID-19) are dying in isolation without the comfort of their family or other social support in unprecedented numbers. Recently, healthcare teams at COVID-19 epicenters have been inundated with critically ill patients. Patients isolated for COVID-19 have had no contact with their family or loved ones and may have likely experienced death without closure. This situation highlights concerns about patients' psychological and spiritual well-being with COVID-19 and their families, as they permanently part ways. While palliative care has advanced to adequately address these patients' needs, the COVID-19 pandemic presents several barriers that force healthcare teams to deprioritize these essential aspects of patient care. The severe acute respiratory syndrome (SARS) outbreak in 2003 gave us a glimpse of these challenges as these patients were also isolated in hospitals. Here, we discuss the importance of the biopsychosocial spiritual model in end-of-life care and its implications on patients dying with COVID-19. Furthermore, we outline an integrative approach to address the unique and holistic needs of critically ill patients dying with COVID-19. These include intentional and increased coordination with trained palliative care staff, early and frequent goals of care including discussion of end-of-life plans, broader use of technology to improve connectedness, and shared decision making with patients' families.

Systematic Review and Meta-Analysis of Sex-Specific COVID-19 Clinical Outcomes.

To successfully mitigate the extraordinary devastation caused by the Coronavirus disease 2019 (COVID-19) pandemic, it is crucial to identify important risk factors for this disease. One such neglected health determinant is the sex of the patient. This is an essential clinical characteristic, as it can factor into a patient's clinical management and preventative measures. Some clinical studies have shown disparities in the proportion between males and females that have more severe clinical outcomes or, subsequently, die from this disease. However, this association has not been unequivocally established. Thus, the purpose of this investigation was to examine the association between male sex and COVID-19 severity. We systematically reviewed the literature, identified studies that matched predetermined selection criteria, and performed a meta-analysis to evaluate the proportion of males among four disease severity categories. Appropriate assessment strategies were implemented to assess and minimize potential biases. The results of this meta-analysis indicated that males constituted a significantly higher proportion of those who had adverse clinical outcomes and died from COVID-19. As the coronavirus spread from the East to the West, male sex remained a consistent risk factor. Our results support the establishment of the male sex as an important risk factor for this disease. Early identification and appropriate medical care for males with lab-confirmed COVID-19 may substantially change the course of clinical prognosis, resulting in greater numbers of lives saved.

Effects of Aerobic and Flexibility Training on Physiological and Psychosocial Function in a Patient with Anaplastic Oligodendroglioma: A Case Report.

OBJECTIVE: Diagnoses of anaplastic oligodendrogliomas are rare. For cancer rehabilitation practitioners, anaplastic oligodendroglioma may impact on the development and maintenance of prescriptive exercise. Exercise interventions for healthy individuals and cancer patients have been shown to increase functional capacity, psychosocial functioning, and aspects of cognitive function. However, there is a lack of research into exercise interventions among patients with anaplastic oligodendroglioma. This case report of a patient with anaplastic oligodendroglioma, measures the effects of aerobic and flexibility training on physiological, psychosocial, and cognitive functioning. PATIENT: A 44-year old woman diagnosed with class III anaplastic oligodendroglioma with 1p19q genetic co-deletion underwent left-frontal craniotomy, chemotherapy, and radiation treatment. Comprehensive physical, psychosocial, and cognitive assessments were completed before and after a 36-session exercise intervention. RESULTS: Following the intervention improvements were observed in 9 of the 14 physiological measures. Fatigue decreased by 20% and quality of life increased by almost 70%. Improvements were also observed in 6 of the 12 cognitive assessment variables. CONCLUSION: The 36 sessions of aerobic and flexibility training were well-tolerated by the subject. The results demonstrate the feasibility and importance of aerobic and flexibility training for the attenuation of cancer-related decrements in physiological and psychosocial variables in patients with anaplastic oligodendroglioma. The effects on cognitive function were uncertain.

Molecular Mechanisms Lead to Sex-Specific COVID-19 Prognosis and Targeted Therapies.

Clinical and epidemiological studies have identified male sex as an important risk factor for COVID-19 clinical outcomes and mortality. This raises the question as to how this risk factor can be addressed in the prognosis, clinical management, and the treatment of patients with Coronavirus disease 2019 (COVID-19). Currently, there are no guidelines or protocols to help alter the course of sex-specific COVID-19 prognosis, especially in severe disease presentations. This is partly due to the lack of research studies characterizing the differences in male vs. female host response to the severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) infection and a lack of a well-rounded understanding of the molecular mechanisms involved. Here, we discuss three distinct but interconnected molecular-level differences in males and females that likely play an essential role in the COVID-19 prognosis. We review interactions of SARS-CoV-2 with host cell angiotensin-converting enzyme 2 (ACE2) in the viral entry between males vs. females and discuss the differential regulation of the renin-angiotensin system (RAS) between the two sexes. Next, we present immune response disparities and how immune function and endocrine regulation may render males increasingly vulnerable to severe COVID-19. We describe the interconnected roles of these three regulatory systems in males and females in response to SARS-CoV-2 infection. Finally, we highlight the clinical implications of these mechanisms to patients with COVID-19 and propose putative targeted therapies that can help reduce COVID-19 severity in those critically ill.

Feasibility of a combined aerobic and cognitive training intervention on cognitive function in cancer survivors: a pilot investigation.

BACKGROUND: Cancer-related cognitive impairment (CRCI) may negatively affect upwards of 75% of cancer patients. Exercise and cognitive training, independently, may increase functional capacity and aspects of cognitive function. Yet, combined training protocols have not been evaluated in cancer survivor populations. Therefore, the aim of this study was to explore the feasibility of a quasi-randomized, controlled, exploratory, repeated-measures aerobic and cognitive training intervention on cognitive function in participants undergoing treatment for cancer (N = 28). METHODS: Pre- and post-physical and cognitive assessments were administered. A 36-session (approximately 12 weeks) computer-based cognitive (COG), aerobic (AER), cognitive and aerobic (AER + COG), and flexibility (CON) training intervention was completed. Dependent measures t tests and pre- to post percentages were then calculated to address within-group changes for each dependent variable. RESULTS: Within-group measures revealed that the AER logical memory scores (pre- to post mean difference [2.3], 95.0% CI [0.9, 3.7], percentage change [32.7%]), delayed recall scores (pre- to post mean difference [2.1], 95.0% CI [0.3, 3.9], percentage change [27.2%]), block design scores (pre- to post mean difference [1.7], 95.0% CI [0.2, 3.2], percentage change [19.0%]), and letter-number sequencing scores (pre- to post mean difference [1.0], 95.0% CI [0.2, 1.8], percentage change [12.3%]) all increased. Aspects of verbal fluidity scores increased in the CON group. However, all cognitive scores (AER + COG and COG groups) failed to increase. CONCLUSIONS: Aerobic training for CRCI may positively impact cognitive function. Individually, these methods may appropriately address CRCI, but combined training of this nature may be too demanding for patients undergoing treatment for cancer. However, larger randomized trials are needed to substantiate this protocol in large-scale cancer rehabilitation centers.

Cancer type does not affect exercise-mediated improvements in cardiorespiratory function and fatigue.

PURPOSE: Despite mounting evidence indicating that exercise training has a positive effect on cancer recovery, the influence of cancer type on the response to exercise training remains uncharacterized. Therefore, the adaptations to exercise training were compared between groups composed of 7 different forms of cancer. METHODS: A total of 319 cancer survivors completed fatigue inventories and participated in assessments of cardiorespiratory function, which encompassed aerobic capacity (VO2 peak), pulmonary function (forced vital capacity [FVC] and forced expiratory volume in 1 second [FEV1]), and resting blood pressure and heart rate. Participants were divided into 7 groups based on cancer type, including breast cancer (BC, n = 170), prostate cancer and other male urogenital neoplasia (PC, n = 38), hematological malignancies (HM, n = 34), colorectal cancer (CC, n = 25), gynecological cancers (GC, n = 20), glandular and epithelial neoplasms (GEN, n = 20), and lung cancer (LC, n = 12). All participants completed an individualized, multimodal exercise intervention consisting of cardiorespiratory, flexibility, balance, and muscular strength training 3 days per week for 3 months. Following the intervention, all subjects were reassessed. Generalized Estimating Equations with exchangeable working correlation structure was used to model each response; the group by time interaction effect represented the effect of cancer type on exercise-associated improvements. RESULTS: No significant (P > .05) group by time interaction effects were observed between different types of cancer for any parameter. Pre- to postexercise contrasts revealed significant improvements in VO2 peak in BC, PC, HM, and GEN at the Bonferroni adjusted significance level (.00714). Heart rate was significantly lowered in the BC and CC groups. Mean fatigue indices decreased by at least 17% in all groups, but these changes were only significant in the BC, HM, CC, and GC groups. Systolic blood pressure decreased significantly in BC and GC, and diastolic blood pressure decreased significantly only in the BC group while pulmonary function remained unchanged in all cancer types. CONCLUSION: Although trends toward improved cardiorespiratory and fatigue parameters only reached significance in some groups, there were no significant differences between cancer types. This suggests that cardiorespiratory and fatigue improvements following rehabilitative exercise are not dependent on cancer type. Further research investigating alternative physiological parameters are needed to confirm the relationship between cancer type and exercise-mediated rehabilitation.
