Influence of A Public Health Emergency On Care For Patients With Duchenne Muscular Dystrophy: An Online, Cross-Sectional Survey (preprint)

Background: The public health emergency has created challenges for the care of patients, particularly those with chronic diseases such as Duchenne muscular dystrophy. To elucidate the challenges faced by Chinese patients with Duchenne muscular dystrophy during the public health emergency coronavirus disease 2019 pandemic, we conducted an online cross-sectional survey, the responses of which were collected between March 27 and June 30, 2021. Results: : In total, valid questionnaire responses were obtained from 2,105 patients, of whom 49 lived in pandemic lockdown areas. Of the 2,056 responders from non-lockdown areas, 42.8% reduced their outside daily activities, 49.4% reduced their use of rehabilitation services, 39.7% postponed regular follow-up appointments, and 40.8% complained of accelerated declines in motor function over the previous year. The corresponding figures for the 49 participants from lockdown areas were almost all higher, with 67.3% reducing outside daily activities, 44.9% reducing their use of rehabilitation services, 79.6% postponing regular follow-up appointments, and 55.1% complaining of accelerated declines in motor function. When asked whether they expected more assistance from society than they had received before the pandemic, 60.8% of patients in non-lockdown areas and 87.8% of those in lockdown areas responded affirmatively. When asked whether they felt more anxious than they had before the pandemic and needed psychological counseling, 11.5% of respondents in non-lockdown areas and 18.4% of respondents in lockdown areas responded affirmatively. In non-lockdown areas, 76% of respondents had at least one telemedicine visit, and 71% of them thought that telemedicine was helpful. In lockdown areas, 91.8% had used telemedicine at least once, and 66.7% of them found it helpful. Conclusions: : These public health emergency control measures have affected the care of patients with chronic diseases worldwide, particularly pronounced in lockdown areas. It is imperative that healthcare workers assist patients and establish more robust chronic disease management systems. Telemedicine is an effective model for providing healthcare to such patients.

Clinical significance of IgM and IgG test for diagnosis of highly suspected COVID-19 infection (preprint)

Quick, simple and accurate diagnosis of suspected COVID-19 is very important for the screening and therapy of patients. Although several methods were performed in clinical practice, however, the IgM and IgG diagnostic value evaluation was little performed. 57 suspected COVID-19 infection patients were enrolled in our study. 24 patients with positive and 33 patients with negative nucleic acid test. The positive rate of COVID-19 nucleic acid was 42.10%. The positive detection rate of combination of IgM and IgG for patients with COVID-19 negative and positive nucleic acid test was 72.73% and 87.50%. The results were significantly higher than the nucleic acid or IgM, IgG single detection. hsCRP in the COVID-19 nucleic acid negative group showed significantly higher than the positive groups (P=0.0298). AST in the COVID-19 IgM negative group showed significantly lower than the positive groups (P=0.0365). We suggest a quick, simple, accurate aided detection method for the suspected patients and on-site screening in close contact with the population.
