ABSTRACT

Purpose: The rapid spread of SARS-CoV-2, the virus that is responsible for causing COVID-19, has presented the medical community with another example of when convalescent plasma (CP) is still used today. The ability to standardize CP at the onset of a pandemic is unlikely to exist in a reliable and uniformly reproducible way. We hypothesized that CP of unknown strength given in a serial manner will promote health and reduce mortality in those inflicted with COVID-19. Methods: Participants were given up to 8 CP-units depending on their condition upon entry into the study and their response. Results: 102 out of 117 participants were given CP. The earlier a participant received CP corelated with survival (p = 0.0004). The number of CP-units given, throughout all the clinical severities, was not significant with outcomes, p = 0.3947. A higher number of CP-units given to the severe/critical participants (without biological immunosuppressants or restrictive lung disease) did correlate with survival p = 0.0116 (2.8 vs. 2 units). Lower platelets on admission corelated with mortality. Platelet levels increase correlated with CP infusions p < 0.0001. Conclusion: This study supports the serial use of CP of unknown strength based on clinical response for those infected with COVID-19. The use of 3-4 units of CP was found to be statistically significant for survival for severe and critical participants without restrictive lung disease and chronic biological immunosuppression. Increased platelet levels after CP infusions supports that CP is promoting overall health regardless of outcomes.

ABSTRACT

OBJECTIVE: We compared outcomes in patients with severe COVID-19 versus non-COVID-19-related acute respiratory distress syndrome (ARDS) managed using a dynamic, goal-driven approach to venovenous extracorporeal membrane oxygenation (ECMO). METHODS: We performed a retrospective, single-center analysis of our institutional ECMO registry using data from 2017 to 2021. We used Kaplan-Meier plots, Cox proportional hazard models, and propensity score analyses to evaluate the association of COVID-19 status (COVID-19-related ARDS vs non-COVID-19 ARDS) and survival to decannulation, discharge, tracheostomy, and extubation. We also conducted subgroup analyses to compare outcomes with the use of extracorporeal cytoreductive techniques (CytoSorb [CytoSorbents Corp] and plasmapheresis). RESULTS: The sample comprised 128 patients, 50 with COVID-19 and 78 with non-COVID-19 ARDS. Advancing age was associated with decreased probability of survival to decannulation (P = .04). Compared with the non-COVID-19 ARDS group, patients with COVID-19 had a greater probability of survival to extubation (P < .01) and comparable survival to discharge (P = .14). CONCLUSIONS: Patients with COVID-19 managed with ECMO had comparable outcomes as patients with non-COVID ARDS. A strategy of early extubation and ambulation might be a safe and effective strategy to improve outcomes and survival, even for patients with severe COVID-19.

ABSTRACT

There is strong evidence of brain-related abnormalities in COVID-191-13. However, it remains unknown whether the impact of SARS-CoV-2 infection can be detected in milder cases, and whether this can reveal possible mechanisms contributing to brain pathology. Here we investigated brain changes in 785 participants of UK Biobank (aged 51-81 years) who were imaged twice using magnetic resonance imaging, including 401 cases who tested positive for infection with SARS-CoV-2 between their two scans-with 141 days on average separating their diagnosis and the second scan-as well as 384 controls. The availability of pre-infection imaging data reduces the likelihood of pre-existing risk factors being misinterpreted as disease effects. We identified significant longitudinal effects when comparing the two groups, including (1) a greater reduction in grey matter thickness and tissue contrast in the orbitofrontal cortex and parahippocampal gyrus; (2) greater changes in markers of tissue damage in regions that are functionally connected to the primary olfactory cortex; and (3) a greater reduction in global brain size in the SARS-CoV-2 cases. The participants who were infected with SARS-CoV-2 also showed on average a greater cognitive decline between the two time points. Importantly, these imaging and cognitive longitudinal effects were still observed after excluding the 15 patients who had been hospitalised. These mainly limbic brain imaging results may be the in vivo hallmarks of a degenerative spread of the disease through olfactory pathways, of neuroinflammatory events, or of the loss of sensory input due to anosmia. Whether this deleterious effect can be partially reversed, or whether these effects will persist in the long term, remains to be investigated with additional follow-up.

ABSTRACT

The COVID-19 pandemic is a global health issue which has severely disrupted and deferred several landmark international sporting competitions. Like the general population, athletes have faced direct psychological consequences from COVID-19 in addition to cancelation of events, loss of support, lack of training, loss of earnings, hypervigilance, and anxiety among others. The aim of the present research was to identify the adversity experiences of athletes caused by COVID-19 (study 1) and explore the process of resilience used by competitive elite athletes for positive adaptation (study 2). Research has indicated psychological resilience to be a protective factor against similar adversities in the sporting context. The study uses an across-cases qualitative design comparing the real-time lived experiences of athletes during COVID-19 using narrative analysis. Data were collected from 10 competitive elite athletes from various countries, as part of a larger doctoral dissertation study during the lockdown period, using in-depth experiential interviews. Study 1 presents detailed narratives on the loss and incongruence, which were the two major adversities experienced. Study 2 outlines the process of resilience as narrated by the participants through the emergent and minimal-impact resilience trajectories. We discuss recommendations for interventions and the role of sports psychologists, coaches, and sporting organizations in ensuring athletes' mental health and their rehabilitation into post-COVID sports life.

ABSTRACT

The role of extracorporeal membrane oxygenation (ECMO) in the management of critically ill patients with COVID-19 is evolving. Extracorporeal support independently confers an increased predilection for thrombosis, which can be exacerbated by COVID-19-associated coagulopathy. We present the successful management of a hypercoagulable state in two patients who required venovenous ECMO for the treatment of COVID-19. This included monitoring inflammatory markers (D-dimer and fibrinogen), performing a series of therapeutic plasma exchange procedures, and administering high-intensity anticoagulation therapy and thromboelastography- (TEG-) guided antiplatelet therapy. TPE was performed to achieve goal D-dimer less than 3000 ng/mL D-dimer units (N ≤ 232 ng/mL D-dimer units) and goal fibrinogen less than 600 mg/dL (N = 200-400 mg/dL). These therapies resulted in improved TEG parameters and normalized inflammatory markers. Patients were decannulated after 37 days and 21 days, respectively. Post-ECMO duplex ultrasound of the upper and lower extremities and cannulation sites revealed a nonsignificant deep venous thrombosis at the site of femoral cannulation in patient 2 and no deep venous thrombosis in patient 1. The results of this case report show successful management of a hypercoagulable state among COVID-19 patients requiring ECMO support by utilization of inflammatory markers and TEG.
