oronavirus disease 2019 , the pathogen of which is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly infectious disease that broke out in Wuhan, China, in December 2019 and has spread to more than 200 countries. 1 COVID-19 has been proven to be transmitted mainly through droplets and contact. 2 The eye is also considered an important route of infection.According to reports published in recent years, the prevalence of myopia in China is now more than 80% of the population. Wearing of eyeglasses is common among Chinese individuals of all ages. 3 However, since the outbreak of COVID-19 in Wuhan in December 2019, we observed that few patients with eyeglasses were admitted in the hospital ward. There-fore, we collected information on the wearing of eyeglasses from all inpatients with COVID-19 as part of their medical history and used the data to examine the association between wearing eyeglasses and COVID-19 infection. MethodsThis cohort study was approved by the ethics committee of Suizhou Zengdu Hospital, Suizhou, China, and followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline. Patients signed written informed consent and were not provided with any IMPORTANCE The proportion of daily wearers of eyeglasses among patients with coronavirus disease 2019 (COVID-19) is small, and the association between daily wear of eyeglasses and COVID-19 susceptibility has not been reported.OBJECTIVE To study the association between the daily wearing of eyeglasses and the susceptibility to COVID-19. DESIGN, SETTING, AND PARTICIPANTSThis cohort study enrolled all inpatients with COVID-19 in Suizhou Zengdu Hospital, Suizhou, China, a designated hospital for COVID-19 treatment in the area, from January 27 to March 13, 2020. COVID-19 was diagnosed according to the fifth edition of Chinese COVID-19 diagnostic guidelines. The proportion of persons with myopia who wore eyeglasses in Hubei province was based on data from a previous study.EXPOSURES Daily wearing of eyeglasses for more than 8 hours. MAIN OUTCOMES AND MEASURESThe main outcomes were the proportions of daily wearers of eyeglasses among patients admitted to the hospital with COVID-19 and among the local population. Data on exposure history, clinical symptoms, underlying diseases, duration of wearing glasses, and myopia status and the proportion of people with myopia who wore eyeglasses in Hubei province were collected. People who wore glasses for more than 8 hours a day were defined as long-term wearers.RESULTS A total of 276 patients with COVID-19 were enrolled. Of these, 155 (56.2%) were male, and the median age was 51 (interquartile range, 41-58) years. All those who wore glasses for more than 8 hours a day had myopia and included 16 of 276 patients (5.8%; 95% CI, 3.04%-8.55%). The proportion of people with myopia in Hubei province, based on a previous study, was 31.5%, which was much higher than the proportion of patients with COVID-19 who had myopia in this sample. CONCLUSIONS AND RELEVANCEIn this ...
Background: We aimed to report the epidemiological and clinical characteristics of hospitalized patients with coronavirus disease-19 (COVID-19) in Zengdu District, Hubei Province, China. Methods: Clinical data on COVID-19 inpatients in Zengdu Hospital from January 27 to March 11, 2020 were collected; this is a community hospital in an area surrounding Wuhan and supported by volunteer doctors. All hospitalized patients with COVID-19 were included in this study. The epidemiological findings, clinical features, laboratory findings, radiologic manifestations, and clinical outcomes of these patients were analyzed. The patients were followed up for clinical outcomes until March 22, 2020. Severe COVID-19 cases include severe and critical cases diagnosed according to the seventh edition of China's COVID-19 diagnostic guidelines. Severe and critical COVID-19 cases were diagnosed according to the seventh edition of China's COVID-19 diagnostic guidelines. Results: All hospitalized COVID-19 patients, 276 (median age: 51.0 years), were enrolled, including 262 non-severe and 14 severe patients. The proportion of patients aged over 60 years was higher in the severe group (78.6%) than in the non-severe group (18.7%, p < 0.01). Approximately a quarter of the patients (24.6%) had at least one comorbidity, such as hypertension, diabetes, or cancer, and the proportion of patients with comorbidities was higher in the severe group (85.7%) than in the non-severe group (21.4%, p < 0.01). Common symptoms included fever (82.2% [227/276]) and cough (78.0% [218/276]). 38.4% (106/276) of the patients had a fever at the time of admission. Most patients (94.9% [204/276]) were cured and discharged; 3.6% (10/276) deteriorated to a critical condition and were transferred to another hospital. The median COVID-19 treatment duration and hospital stay were 14.0 and 18.0 days, respectively.

This meta-analysis was conducted to explore the relationship between gastrointestinal symptoms and the severity of COVID-19. Methods We searched PubMed, Web of Science, Science Direct, Embase, and Google Scholar on 16 October 2020, to identify observational studies that provided data on gastrointestinal symptoms and severity of COVID-19. Gastrointestinal symptoms include diarrhea, abdominal pain, nausea, and vomiting. The severe rate and the odds ratio (OR) were pooled. Heterogeneity was assessed using the I 2 statistic. Results A total of 21 studies with 5285 patients were included in this meta-analysis. The severe rate of COVID-19 patients with diarrhea was 41.1% [95% confidence interval (CI): 31.0-51.5%], and the OR of association between diarrhea and severe COVID-19 was 1.41 (95% CI: 1.05-1.89); sensitivity analysis showed that the results for the OR and 95% CI were unstable. For abdominal pain, the severe rate and OR of association with severe COVID-19 were 59.3% (95% CI: 41.3-76.4%) and 2.76 (95% CI: 1.59-4.81), respectively; for nausea, 41.4% (95% CI: 23.2-60.7%) and 0.92 (95% CI: 0.59-1.43), respectively; for vomiting, 51.3% (95% CI: 36.8-65.8%) and 1.68 (95% CI: 0.97-2.92), respectively. Conclusion The severe rate was more than 40% in COVID-19 patients with gastrointestinal symptoms. Abdominal pain was associated with a near 2.8-fold increased risk of severe COVID-19; the relationship between diarrhea and the severity of COVID-19 was regionally different; nausea and vomiting were limited in association with an increased risk of severe COVID-19.
Pediatric cases of coronavirus disease 2019 (COVID-19) have been reported. This meta-analysis was aimed at describing the clinical, laboratory, and imaging characteristics of children with COVID-19 based on published data of pediatric COVID-19 cases. Search of PubMed, Embase, Web of Sciences, Science Direct, and Google Scholar for articles published until December 14, 2020, that described the clinical, laboratory, and imaging features of children with COVID-19. Data were extracted independently by 2 authors. Random-effects meta-analysis models were used to report pooled results. Clinical data from 2874 children with COVID-19 from 37 articles were finally included for quantitative analyses. Fever (48.5%, 95% CI: 41.4%–55.6%) and cough (40.6%, 95% CI: 33.9%–47.5%) were the most common symptoms; asymptomatic infection and severe cases, respectively, accounted for 27.7% (95% CI: 19.7%–36.4%) patients and 1.1% of the 1933 patients included. Laboratory tests showed 5.5% (95% CI: 2.8%–8.9%) of the patients had lymphopenia. The pooled prevalence of leukopenia was 7.3% (95% CI: 3.4%–12.2%), and the C-reactive protein level was high in 14.0% (95% CI: 6.8%–22.8%). Chest computed tomography showed unilateral and bilateral lesions, and ground-glass opacity in 29.4% (95% CI: 24.8%–34.3%) and 24.7% (95% CI: 18.2%–31.6%), and 32.9% (95% CI: 25.3%–40.9%), respectively, and normal in approximately 36.0% (95% CI: 27.7%–44.7%). We found that children with COVID-19 had relatively mild disease, with quite a lot of asymptomatic infections and low rate of severe illness. Data from more regions are needed to determine the prevention and treatment strategies for children with COVID-19.
