Immunologic and Autoimmune-Related Sequelae of Severe Acute Respiratory Syndrome Coronavirus 2 Infection: Clinical Symptoms and Mechanisms of Disease.

The COVID-19 pandemic has resulted in a significant number of people developing long-term health effects of postacute sequelae SARS-CoV-2 infection (PASC). Both acute COVID-19 and PASC are now recognized as multiorgan diseases with multiple symptoms and disease causes. The development of immune dysregulation during acute COVID-19 and PASC is of high epidemiologic concern. Both conditions may also be influenced by comorbid conditions such as pulmonary dysfunction, cardiovascular disease, neuropsychiatric conditions, prior autoimmune conditions and cancer. This review discusses the clinical symptoms, pathophysiology, and risk factors that affect both acute COVID-19 and PASC.

Neurologic and Neuromuscular Sequelae of COVID-19.

It is known that there can be neurologic complications related to acute infection with SARS-CoV-2, the virus that causes COVID-19. Currently, there is a growing body of evidence that postacute sequelae of SARS-CoV-2 infection can manifest as neurologic sequelae as a result of direct neuroinvasion, autoimmunity, and possibly lead to chronic neurodegenerative processes. Certain complications can be associated with worse prognosis, lower functional outcome, and higher mortality. This article provides an overview of the known pathophysiology, symptoms presentation, complications and treatment approaches of the post-acute neurologic and neuromuscular sequelae of SARS-CoV-2 infection.

Autonomic Dysfunction Related to Postacute SARS-CoV-2 Syndrome.

Persistence of symptoms beyond the initial acute phase of coronavirus disease-2019 (COVID-19) is termed postacute SARS-CoV-2 (PASC) and includes neurologic, autonomic, pulmonary, cardiac, psychiatric, gastrointestinal, and functional impairment. PASC autonomic dysfunction can present with dizziness, tachycardia, sweating, headache, syncope, labile blood pressure, exercise intolerance, and "brain fog." A multidisciplinary team can help manage this complex syndrome with nonpharmacologic and pharmacologic interventions.

Immunologic and Autoimmune Related Sequelae of SARS-CoV-2 infection: Clinical Symptoms and Mechanisms of Disease

The continued Coronavirus Disease 2019 (COVID-19) pandemic has resulted in over 600 million infections worldwide, with 10-30% of patients experiencing post-acute sequelae of SARS-CoV-2 (PASC). Despite initial signs of COVID-19 as a primarily respiratory disease, it has become clear that there is multi-organ dysfunction that can occur both in the acute stage of SARS-CoV-2 infection and PASC. Mechanistically, it is known that SARS-CoV-2 enters cells through an interaction between angiotensin-converting enzyme 2 receptor and SARS-CoV-2 Spike protein and leads to an acute illness that can last between one to four weeks. Less is known about the exact mechanism of PASC, although several proposed possibilities include direct SARS-CoV-2 tissue invasion, persistent inflammation and rise of autoimmunity, as well as potential persistence of SARS-CoV-2 virus or immunogenicity from residual SARS-CoV-2 RNA. Co-morbid conditions such as pulmonary dysfunction, cardiovascular disease, neuropsychiatric conditions, autoimmunity, hypogammaglobulinemia, and cancers likely contribute to presentation and disease outcomes in both acute SARS-CoV-2 infection and PASC. In this review, we compare evolving information on clinical symptoms, pathophysiology, and co-morbid disease risk factors between acute COVID-19 and PASC.

Telemedicine Use Among Physiatrists During the Early Phase of the COVID-19 Pandemic and Potential for Future Use.

Introduction: With the coronavirus disease 2019 (COVID-19) pandemic causing the need for social distancing, telemedicine saw a significant increase in use to provide routine medical care. As a field, physiatry had already been implementing telemedicine prior to the pandemic. In this study, we characterized the use of telemedicine among physiatrists during the early phase of the COVID-19 pandemic to understand the barriers and facilitators to implementing telemedicine use in the field of physiatry in the future. Methods: Online survey of a cross-sectional sample of physiatrists. Analysis was conducted using logistic regression. Results: One hundred seventy one (n = 171) participants completed the survey. Before the pandemic, only 17.5% of respondents used telemedicine. In the logistic regression, physicians who used a hospital-provided platform were more likely to use telemedicine in the future compared with those who used their own secure platform, conducted a phone visit, and used a non-secure platform or other platforms. The three most popular barriers identified were "inability to complete the physical examination," "patients lack of access to technology," and "patients lack of familiarity with the technology." Discussion: Focus on education on telemedicine functional examination strategies and technology strategies for patients and providers (including addressing the digital divide and hospital-provided secure platforms) are potential targets of implementation strategies for greater telemedicine uptake for physiatrists in the future.

Development and Implementation of an International Virtual Didactic Series for Physical Medicine and Rehabilitation Graduate Medical Education During COVID-19.

ABSTRACT: Coronavirus disease of 2019 presented significant challenges to residency and fellowship programs. Didactic lectures were particularly affected as redeployment of faculty and trainees, limitations on in-person gathering, and other barriers limited opportunities for educational engagement. We sought to develop an online didactic series to address this gap in graduate medical education.Lecturers were recruited via convenience sample and from previous Association of Academic Physiatrists presenters from across the United States and Canada; these presented via Zoom during April and May 2020. Lecturers and content reflected the diverse nature of the specialty. Learning objectives were adapted from the list of board examination topics provided by the American Board of Physical Medicine and Rehabilitation.Fifty-nine lectures were presented. Maximum concurrent live viewership totaled 4272 and recorded lecture viewership accounted for an additional 6849 views, for a total of at least 11,208 views between the date of the first lecture (April 9, 2020) and May 1, 2021. Live viewers of one of the lectures reported participating from several states and 16 countries.The Association of Academic Physiatrists-led virtual didactics augmented graduate medical education during the coronavirus disease of 2019 pandemic, and data confirm that the lectures have continued to enjoy a high level of viewership after the cessation of live lectures.

Rehabilitation Strategies for Cognitive and Neuropsychiatric Manifestations of COVID-19.

Purpose of Review: Extrapulmonary manifestations of COVID-19 are abundant, including after recovery of acute SARS-CoV-2 infection. This review seeks to explore the cognitive and neuropsychiatric manifestations of COVID-19 and post-acute sequelae of SARS-CoV-2 (PASC), including Long COVID syndromes. Furthermore, the review will discuss rehabilitation strategies for the emerging neurological consequences of COVID-19 to help those experiencing long-term effects of COVID-19. Recent Findings: There is emerging evidence depicting the neural involvement of COVID-19. Health priorities have shifted from understanding pathogenesis and treatment of pulmonary symptoms to targeting the acute and chronic sequelae of COVID-19, including cognitive and neuropsychiatric symptoms. The sequelae of COVID-19 often co-occur with other medical problems and is best managed by assessment and care across multiple disciplines. Symptoms following infection are similar to those found by other syndromes and disorders that disrupt the central nervous system. Summary: The acute and chronic sequelae of COVID-19 have become major targets of current health care providers given its significant public health impact, inclusive of cognitive and neuropsychiatric sequelae. Assessment and referral to rehabilitation based on each individual's needs and symptoms can decrease morbidity and improve quality of life.

Enhanced external counterpulsation for management of symptoms associated with long COVID

Study objective Enhanced external counterpulsation (EECP) as a possible therapy for Long COVID. Design Retrospective analysis of a contemporary, consecutive patient cohort. Setting 7 outpatient treatment centers. Participants Long COVID patients. Intervention 15–35 EECP treatments. Main outcome measures The change from baseline in 1) Patient Reported Outcome Measurement Information System (PROMIS) Fatigue;2) Seattle Angina Questionnaire (SAQ-7);3) Duke Activity Status Index (DASI);4) 6-Minute Walk Test (6MWT);5) Canadian Cardiovascular Society (CCS) Angina Grade;6) Rose Dyspnea Scale (RDS);and 7) Patient Health Questionnaire (PHQ-9). Results Compared to baseline, the PROMIS Fatigue, SAQ7, DASI, and 6MWT improved by 4.63 ± 3.42 (p < 0.001), 21.44 ± 16.54 (p < 0.001), 18.08 ± 13.82 (p < 0.001), and 200.00 ± 180.14 (p = 0.002), respectively. CCS and RDS improved in 63% and 44% of patients, respectively. All patients unable to work prior to EECP were able to return post-therapy. Conclusions and relevance EECP significantly improved validated fatigue and cardiovascular-related markers in patients with Long COVID.

Models of Care for Postacute COVID-19 Clinics: Experiences and a Practical Framework for Outpatient Physiatry Settings.

ABSTRACT: After surviving infection with the SARS-CoV-2 virus, individuals may have persistent symptoms and prolonged impairments that may last for weeks to months. The frequency and heterogeneity of persistent post-COVID conditions have created challenges in care. Specialty clinics are being established in response to an increasing need to care for patients with postacute sequelae of SARS-CoV-2 or long COVID syndrome. Although many post-COVID conditions can be bettered through a comprehensive rehabilitation plan, various clinical settings may benefit from differing models of coordinated care. We present five models of care in varying degrees of development and compare processes and adaptations to address the unique needs of each center and their unique patient populations. Forging a path to recovery will necessitate a multidisciplinary team with physiatry involvement to meet the distinctive needs of patients with postacute sequelae of SARS-CoV-2. Furthermore, it is imperative that there be equitable access to this care and commitment from healthcare institutions to provide resources for these programs.
