ABSTRACT
Objective To investigate the psychological characteristics of college students during the outbreak of coronavirus disease 2019 (COVID-19), so as to provide a basis for psychological intervention. Methods From May 17, 2020 to Jun. 17, 2020, the adjusted psychological questionnaires for emergent events of public health (PQEEPH) was surveyed among the college students of Beijing Union University. The questionnaire included 5 dimensions: depression, neurasthenia, fear, obsessive-compulsive anxiety, and hypochondriasis. Four grades were scored according to the degree and frequency of emotional responses: 0 means no symptoms, 1 means mild symptoms, 2 means moderate symptoms, and 3 means severe symptoms. Results A total of 3 019 valid questionnaires were collected. During the COVID-19 epidemic, the emotional responses of college students, from the most serious to the least, were fear, neurasthenia, depression, obsessive-compulsive anxiety, and hypochondriasis, with the incidences being 87.7% (2 648/3 019), 44.8% (1 353/3 019), 37.4% (1 129/3 019), 17.3% (522/3 019), and 11.6% (350/3 019), respectively. The fear scores of female students were higher than those of male students (P<0.001), the fear scores of college students from towns/suburbs were higher than those from rural and urban areas (both P<0.017), the scores of depression, neurasthenia and obsessive-compulsive anxiety of college students with confirmed COVID-19 cases around them or their relatives participated in the epidemic prevention and control as medical staff or logistics support personnel were higher than those without such conditions (all P<0.017), and the scores of depression, obsessive-compulsive anxiety and hypochondriasis of college students with suspected COVID-19 cases around them were higher than those without such condition (all P<0.017). Females were more likely to have moderate to severe fear than males (odds ratio[OR]=1.53, 95% confidence interval[CI]1.25-1.88, P<0.001), those with confirmed or suspected COVID-19 cases around them were more likely to have moderate to severe fear than those without such conditions (OR=2.03, 95% CI 1.29-3.20, P=0.002), and those living in towns/suburbs were more likely to have moderate to severe fear than those living in rural and urban areas (OR=0.72, 95% CI 0.56-0.94, P=0.015;OR=0.78, 95% CI 0.63-0.97, P=0.025). Conclusion COVID-19 epidemic has impact on the psychology of college students. It is necessary to pay attention to the mental health of college students and provide targeted psychological counseling for them.Copyright © 2022, Second Military Medical University Press.

ABSTRACT
OBJECTIVE: There is concern that the coronavirus disease (COVID-19) vaccine may trigger or worsen autoimmune diseases. The objective of this study was to determine the impacts of COVID-19 vaccination on symptom severity in patients with myasthenia gravis (MG). METHODS: A total of 106 enrolled patients with MG who were vaccinated against COVID-19 were followed up, and a questionnaire was used to document in detail the exacerbation of muscle weakness after vaccination and all other uncomfortable reactions after vaccination. Demographic, clinical characteristics, medication, and vaccination data were collected by follow-up interview. The main observation outcome was whether the MG symptoms of patients were exacerbated. The definition of exacerbation is according to the subjective feeling of the patient or a 2-point increase in daily life myasthenia gravis activity score relative to before vaccination, within 30 days after vaccination. RESULTS: Of 106 enrolled patients [median age (SD) 41.0 years, 38 (35.8%) men, 53 (50.0%) with generalized MG, 74 (69.8%) positive for acetylcholine receptor antibody, and 21 (19.8%) with accompanying thymoma], muscle weakness symptoms were stable in 102 (96.2%) patients before vaccine inoculation. Muscle weakness worsened in 10 (9.4%) people after vaccination, of which 8 patients reported slight symptom worsening that resolved quickly (within a few days). Two (1.9%) of patients showed serious symptom aggravation that required hospitalization. CONCLUSION: Our results suggest that inactivated virus vaccines against COVID-19 may be safe for patients with MG whose condition is stable. Patients with generalized MG may be more likely to develop increased muscle weakness after vaccination.
ABSTRACT
Objective: To explore the related factors of negative conversion time (NCT) of nucleic acid in children with COVID-19. Methods: A retrospective cohort study was conducted. A total of 225 children who were diagnosed with COVID-19 and admitted to Changxing Branch of Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 3rd to May 31st 2022 were enrolled in the study. The infection age, gender, viral load, basic disease, clinical symptoms and information of accompanying caregivers were retrospectively analyzed. According to age, the children were divided into<3 years of age group and 3-<18 years of age group. According to the viral nucleic acid test results, the children were divided into positive accompanying caregiver group and negative accompanying caregiver group. Comparisons between groups were performed using Mann-Whitney U test or Chi-square test. Multivariate Logistic regression analysis was used to analyze the related factors of NCT of nucleic acid in children with COVID-19. Results: Among the 225 patients (120 boys and 105 girls) of age 2.8 (1.3, 6.2) years, 119 children <3 years and 106 children 3-<18 years of age, 19 cases were diagnosed with moderate COVID-19, and the other 206 cases were diagnosed with mild COVID-19. There were 141 patients in the positive accompanying caregiver group and 84 patients in the negative accompanying caregiver group.Patients 3-<18 years of age had a shorter NCT (5 (3, 7) vs.7 (4, 9) d, Z=-4.17, P<0.001) compared with patients <3 years of age. Patients in the negative accompanying caregiver group had a shorter NCT (5 (3, 7) vs.6 (4, 9) d,Z=-2.89,P=0.004) compared with patients in the positive accompanying caregiver group. Multivariate Logistic regression analysis showed that anorexia was associated with NCT of nucleic acid (OR=3.74,95%CI 1.69-8.31, P=0.001). Conclusion: Accompanying caregiver with positive nucleic acid test may prolong NCT of nucleic acid, and decreased appetite may be associated with prolonged NCT of nucleic acid in children with COVID-19.
