What Is the Impact of the COVID-19 Pandemic on Quality of Life and Other Patient-reported Outcomes? An Analysis of the Hand-Wrist Study Cohort.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic, and its associated lockdowns in many parts of the world, have changed our daily lives and may have a psychological impact on around the globe. However, it is unknown how this influences the patient-reported outcome measures (PROMs) of patients involved in ongoing clinical research and medical care. For both the current and potential future lockdowns, it is important to determine if PROMs collected during such a period can be interpreted with confidence. QUESTIONS/PURPOSES: (1) Is there a difference in quality of life between patients in the COVID-19 period group (March 23, 2020 to May 4, 2020) and patients in a reference period group (from the same period in 2018 or 2019)? (2) Is there a difference in pain, hand function, anxiety, depression, and illness perception between patients in the COVID-19 period group and patients in the reference period group? METHODS: This study was part of a large cohort study with routine outcome measures of patients with hand and wrist conditions. To answer our research questions, we analyzed two samples because not all PROMs were sent to participants at the same time points after treatment. The first sample consisted of all participants who completed PROMs on quality of life (QoL), pain, and hand function at their final follow-up time point, which was either 3, 6, or 12 months post-treatment. The second sample consisted of participants who completed PROMs 3 months post-treatment on anxiety, depression, and illness perception. Each sample consisted of two groups: a COVID-19 period group and a reference period group. We included 1613 participants in the first sample (COVID-19 period group: n = 616; reference period group: n = 997) and 535 participants in the second sample (COVID-19 period group: n = 313; reference period group: n = 222). The primary outcome was QoL, expressed in the EuroQol 5-Dimensions questionnaire (EQ-5D) index score. Secondary outcomes were the other domains on the EQ-5D, as well as pain, hand function, anxiety, depression, and illness perception. RESULTS: We found no between-group differences in the EQ-5D index score (standardized mean difference 0.035; p = 0.98). Furthermore, there were no between-group differences in PROM scores for hand function, anxiety, or depression. There were, however, a few small differences in subdomain items regarding pain and illness perception, but we believe in aggregate that these are unlikely to make a clinically important difference in our main finding. CONCLUSION: The COVID-19 pandemic and its associated lockdown had no influence on QoL and had little influence on secondary outcomes in participants who were part of the Hand-Wrist Study Cohort. This finding implies that PROMs data collected during this period can be used with confidence in clinical research. Our findings indicate that when a pandemic like this occurs again, we can continue to use PROMs for analysis in clinical research or routine outcome measures. LEVEL OF EVIDENCE: Level III, therapeutic study.

Neurological Manifestations of SARS-CoV-2: A Narrative Review.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic started as an outbreak in China and soon crossed borders to affect the populations in all countries of the world. During the initial course of the disease, COVID-19 was perceived as a pneumonia-like illness. However, recent findings of COVID-19 patients suggest that the virus has the potential to disseminate to different tissues and organs, and cause significant complications. SUMMARY: Neurological symptoms are of great significance as these usually present in and complicate critical cases. Many case reports and case series have documented the findings of neurological complications in COVID-19 patients. From the existing data, the most frequent symptoms in these patients were broadly classified into the central nervous system (CNS), peripheral nervous system, and skeletal muscular symptoms. CNS symptoms include meningitis, encephalitis, cerebrovascular complications, peripheral nervous system symptoms include anosmia, ageusia, and skeletal muscular symptoms include myalgias. It is postulated that the cause may be direct CNS injury through blood and neuronal pathways or indirectly because of an immune-mediated response, hypoxia caused by decreased oxygen saturation, or by the binding of subacute respiratory syndrome-coronavirus-2 to the host angiotensin-converting enzyme-2 receptors. Striking radiologic findings in COVID-19 patients with neurological symptoms have also emerged. CONCLUSIONS: As subacute respiratory syndrome-coronavirus-2 may potentially have lethal implications on the nervous system, it is important that neurologists are better informed about the spectrum of clinical manifestations, radiologic findings, and likely mechanisms of injury. Understanding the symptoms and radiologic imaging allows clinicians to consider brain imaging in any patient with suspected COVID-19 and neurological symptoms.

Multisystem effects of COVID-19: a concise review for practitioners.

While COVID-19 has primarily been characterized by the respiratory impact of viral pneumonia, it affects every organ system and carries a high consequent risk of death in critically ill patients. Higher sequential organ failure assessment (SOFA) scores have been associated with increased mortality in patients critically ill patients with COVID-19. It is important that clinicians managing critically ill COVID-19 patients be aware of the multisystem impact of the disease so that care can be focused on the prevention of end-organ injuries to potentially improve clinical outcomes. We review the multisystem complications of COVID-19 and associated treatment strategies to improve the care of critically ill COVID-19 patients.

Autoimmune and rheumatic musculoskeletal diseases as a consequence of SARS-CoV-2 infection and its treatment.

The coronavirus disease-2019 (COVID-19) pandemic is likely to pose new challenges to the rheumatology community in the near and distant future. Some of the challenges, like the severity of COVID-19 among patients on immunosuppressive agents, are predictable and are being evaluated with great care and effort across the globe. A few others, such as atypical manifestations of COVID-19 mimicking rheumatic musculoskeletal diseases (RMDs) are being reported. Like in many other viral infections, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection can potentially lead to an array of rheumatological and autoimmune manifestations by molecular mimicry (cross-reacting epitope between the virus and the host), bystander killing (virus-specific CD8 + T cells migrating to the target tissues and exerting cytotoxicity), epitope spreading, viral persistence (polyclonal activation due to the constant presence of viral antigens driving immune-mediated injury) and formation of neutrophil extracellular traps. In addition, the myriad of antiviral drugs presently being tried in the treatment of COVID-19 can result in several rheumatic musculoskeletal adverse effects. In this review, we have addressed the possible spectrum and mechanisms of various autoimmune and rheumatic musculoskeletal manifestations that can be precipitated by COVID-19 infection, its therapy, and the preventive strategies to contain the infection.

COVID-19 and Management of Orthopedic Emergencies. Producing a Consensus of Experts.

OBJECTIVE: Report the results of a participatory approach in Tunisian orthopedic surgery, for the development of a consensus of experts, on the identification of the list of pathologies to always be considered as non-postponable emergencies, during the COVID-19 pandemic. MATERIAL AND METHODS: This descriptive study of the opinions of Tunisian experts covered all orthopedic morbidities classified into three homogeneous groups: trauma, infections and tumors of the musculoskeletal system. The attitudes of the interviewees were collected using the "Delphi" method, using a "Google-Form" questionnaire, sent by email to all of the Tunisian university orthopedic surgeons in practice, and registered at the SOTCOT. Consensus has been established for an item, if validated by at least 80% of the experts. The analysis of the results focused on the first 30 responses to this "online" form. RESULTS: Tunisian experts agreed on the continuity of the urgency of taking in charge all the items of orthopedic morbidity during the COVID-19 pandemic, apart from the following affections: aseptic nonunions in the upper and lower limbs, aggressive giant cell tumors, and hyperalgesic disc herniations, where agreement rates were only at 8%, 12%, 58% and 77%. CONCLUSION: Relative to its disciplinary and professional specificities, the majority the of orthopedic conditions were still considered as emergencies, during the COVID-19 pandemic, which did not lend to postponement of the surgery. However, their management should obey to the recommendations of "Sorting" and the " COVID-19 Patient Pathway ", established by national authorities.
