Background: With over 37.8 million cases and over 1 million deaths worldwide, the COVID-19 pandemic has created a societal and economic upheaval of unparalleled magnitude. A positive transformation has been brought about by innovative solutions in the health care sector that aim to mitigate the impact of COVID-19 on human health. For instance, the use of telehealth has been on the rise amidst this public health emergency.
Objective: Given the unprecedented scale of the pandemic with no definitive endpoint, we aimed to scope the existing telehealth-related literature during a defined period of the ongoing pandemic (ie, January to June 2020).
Methods: Our scoping review was guided by the Joanna Briggs Institute Reviewer Manual. We systematically searched PubMed and Embase databases with specific eligibility criteria. Data extracted from the shortlisted articles included first author and affiliation, journal title, publication type, terminologies used to describe telehealth and their accompanying definitions, health discipline or medical specialties and subspecialties wherein telehealth had been applied, the purpose of telehealth use, and the authors’ overall sentiment on telehealth use. We collated the available information and used descriptive statistics to analyze the synthesized data.
Results: In all, 543 articles published across 331 different journals were included in this scoping review. The Journal of Medical Internet Research and its sister journals featured the highest number of articles (25/543, 4.6%). Nearly all (533/543, 98.2%) articles were in English. The majority of the articles were opinions, commentaries, and perspectives (333/543, 61.3%). Most authors of the articles reviewed were from high-income countries (470/543, 86.6%), especially from the United States of America (237/543, 43.6%). In all, 39 different definitions were used to describe terms equivalent to telehealth. A small percentage (42/543, 7.7%) of the articles focused on the provision of COVID-19–related care. Moreover, 49.7% (270/543) of the articles primarily focused on the provision of multiple components of clinical care, and 23% (125/543) of the articles focused on various specialties and subspecialties of internal medicine. For a vast majority (461/543, 84.9%) of the articles, the authors expressed a celebratory sentiment about the use of telehealth.
Conclusions: This review identified considerable emerging literature on telehealth during the first six months of the COVID-19 pandemic, albeit mostly from high-income countries. There is compelling evidence to suggest that telehealth may have a significant effect on advancing health care in the future. However, the feasibility and application of telehealth in resource-limited settings and low- and middle-income countries must be established to avail its potential and transform health care for the world’s population. Given the rapidity with which telehealth is advancing, a global consensus on definitions, boundaries, protocols, monitoring, evaluation, and data privacy is urgently needed.

Use of Telehealth During the COVID-19 Pandemic: Scoping Review.

224th ENMC International Workshop:: Clinico-sero-pathological classification of immune-mediated necrotizing myopathies Zandvoort, The Netherlands, 14-16 October 2016.

Statins are widely used and lower the risk of death from cardiovascular causes. In a fraction of patients, an autoimmune myopathy may develop, characterized by the development of autoantibodies to the target enzyme, HMG-CoA reductase.

Statin-Associated Autoimmune Myopathy.

Objective To elucidate the common and distinct clinical features of immune-mediated necrotising myopathy (IMNM), also known as necrotising autoimmune myopathy associated with autoantibodies against signal recognition particle (SRP) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR). Methods We examined a cohort of 460 patients with idiopathic inflammatory myopathies (IIMs) through a muscle biopsy-oriented registration study in Japan. Study entry was strictly determined by the comprehensive histological assessment to exclude other neuromuscular disorders. Anti-SRP and anti-HMGCR antibodies were detected by RNA immunoprecipitation and ELISA, respectively. Results Of 460 patients with IIM, we diagnosed 73 (16%) as having inclusion body myositis (IBM). Of 387 patients with IIMs other than IBM, the frequencies of anti-SRP and anti-HMGCR antibodies were 18% and 12%, respectively. One patient had both autoantibodies. Severe limb muscle weakness, neck weakness, dysphagia, respiratory insufficiency and muscle atrophy were more frequently observed in patients with anti-SRP antibodies than in those with anti-HMGCR antibodies. Serum creatine levels were markedly higher in the patients with autoantibodies than in those without. Histology was characterised by necrosis and regeneration of muscle fibres and was consistent with IMNM except in 1 HMGCR-positive IBM patient. Most patients were initially treated with corticosteroids; however, additional immunosuppressive drugs were required, especially in the patients with anti-SRP antibodies. Rates of unsatisfactory neurological outcome were similar in the 2 autoantibody groups. Conclusions Anti-SRP antibodies are associated with severe neurological symptoms, more so than are anti-HMGCR antibodies. Although these autoantibodies are independent serological markers associated with IMNM, patients bearing either share common characteristics.

Diagnosis, Prevention, and Management of Statin Adverse Effects and Intolerance: Canadian Consensus Working Group Update (2016)

Importance Necrotizing autoimmune myopathy (NAM) is characterized pathologically by necrotic muscle fibers with absent or minimal inflammation. It is often accompanied by statin therapy, connective tissue diseases, cancer, and autoantibodies specific for signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl–coenzyme A reductase (HMGCR). Data are limited concerning differences among etiologic subgroups and treatment outcomes in NAM. Objectives To describe the clinical, serologic, and electrophysiologic characteristics of NAM, compare patient subgroups, and determine clinical outcome predictors. Design, Setting, and Participants We conducted a retrospective review of medical records for 63 adult Mayo Clinic patients assigned the clinical and histopathologic diagnosis of NAM from January 1, 2004, through December 31, 2013. Patients were stratified by presumed cause and autoantibody status. Main Outcomes and Measures Clinical, electrophysiologic, and pathologic characteristics were collected and compared among patient subgroups. Predictors of response to treatment were identified by univariate logistic regression. Results Lower extremity weakness predominated (46 [73%]). Distal weakness (26 [41%]), dysphagia (22 [35%]), and dyspnea (23 [37%]) were common. Twenty-two patients (35%) were receiving a statin medication at onset, 6 had cancer, and 3 had a connective tissue disease. The median creatine kinase level was 5326 U/L. In 13 patients (24%), SRP-IgG was detected, and in 17 patients (34%), HMGCR-IgG was detected (one-third of whom had not received statin medication). One patient was dual seropositive. Facial weakness was more common in SRP-IgG–positive patients. Myotonic discharges were more common in statin-associated NAM. Prednisone monotherapy was insufficient to control disease in most patients; 30 (90%) of 32 patients required 2 or more immunotherapeutic agents. Relapse occurred in 16 (55%) of 29 patients during immunosuppressant taper or discontinuation. Predictors of favorable outcome were male sex and use of 2 or more immunotherapeutic agents within 3 months of onset. Conclusions and Relevance Necrotizing autoimmune myopathy was idiopathic in half of this cohort with clinical and histopathologically defined disease. In the remainder, NAM was associated with statin medication, cancer, or connective tissue disease. One in 4 patients was SRP-IgG positive, and 1 in 3 was HMGCR-IgG positive. The disease was usually not controlled by corticosteroid monotherapy. Presentation, course, and outcomes did not differ significantly in seropositive, seronegative, and statin-associated cases. Early aggressive immunosuppressant therapy improved outcomes, and risk of relapse was high during medication dose reduction or withdrawal.

Clinical Features and Treatment Outcomes of Necrotizing Autoimmune Myopathy

OBJECTIVE: To outline features of the neurologic examination that can be performed virtually through telemedicine platforms (the virtual neurological examination [VNE]), and provide guidance for rapidly pivoting in-person clinical assessments to virtual visits during the COVID-19 pandemic and beyond. METHODS: The full neurologic examination is described with attention to components that can be performed virtually. RESULTS: A screening VNE is outlined that can be performed on a wide variety of patients, along with detailed descriptions of virtual examination maneuvers for specific scenarios (cognitive testing, neuromuscular and movement disorder examinations). CONCLUSIONS: During the COVID-19 pandemic, rapid adoption of virtual medicine will be critical to provide ongoing and timely neurological care. Familiarity and mastery of a VNE will be critical for neurologists, and this article outlines a practical approach to implementation.

Background and Purpose— Stroke is a relatively common and challenging condition in hospitalized patients. Previous studies have shown delays in recognition and assessment of inpatient strokes leading to poor outcomes. The goal of this quality improvement initiative was to evaluate an in-hospital code stroke algorithm and educational program aimed at reducing the response times for inpatient stroke. Methods— An inpatient code stroke algorithm was developed, and an educational intervention was implemented over 5 months. Data were recorded and compared between the 36-month period before and the 15-month period after the intervention was implemented. Outcome measures included time from last seen normal to initial assessment and from last seen normal to brain imaging. Results— During the study period, there were 218 inpatient strokes (131 before the intervention and 87 after the intervention). Inpatient strokes were more common on cardiovascular wards (45% of cases) and occurred mainly during the perioperative period (60% of cases). After implementation of an inpatient code stroke intervention and educational initiative, there were consistent reductions in all timed outcome measures (median time to initial assessment fell from 600 [109–1460] to 160 [35–630] minutes and time to computed tomographic scan fell from 925 [213–1965] to 348.5 [128–1587] minutes). Conclusions— Our study reveals the efficacy of an inpatient code stroke algorithm and educational intervention directed at nurses and allied health personnel to optimize the prompt management of inpatient strokes. Prompt assessment may lead to faster stroke interventions, which are associated with better outcomes.

In-Patient Code Stroke: A Quality Improvement Strategy to Overcome Knowledge-to-Action Gaps in Response Time.

Introduction: In acid maltase deficiency (AMD), electrical myotonia (EM) may be restricted to paraspinal muscles. A comprehensive description of the electromyographic (EMG) findings in AMD is lacking. The purpose of this study is to describe the EMG features in adult-onset AMD, focusing on the distribution of EM. Methods: A retrospective chart review of AMD patients diagnosed at Mayo Clinic over age 18 years. Results: Thirty-seven patients were included. Twenty-eight (76%) had EM in at least 1 muscle, and EM was more common in paraspinal and proximal limb muscles. The tensor fasciae latae (TFL) was equally sensitive to the paraspinals for EM. Three of 4 patients had EM identified in the diaphragm. Conclusions: Approximately three-quarters of adult-onset AMD patients display EM on EMG. The paraspinal muscles and TFL are the most likely to demonstrate EM, and EM can be detected in the diaphragm of adult onset AMD patients. Muscle Nerve, 2015 Muscle Nerve 51:759–761, 2015
