Attitudes towards and safety of the SARS-CoV-2 inactivated vaccines in 188 patients with systemic lupus erythematosus: a post-vaccination cross-sectional survey.

Vaccination is key in mastering the COVID-19 pandemic. Data on attitudes towards and safety of the SARS-CoV-2 inactivated vaccines in patients with systemic lupus erythematosus (SLE) are limited. A post-vaccination cross-sectional survey was conducted to obtain data on attitudes towards and safety of the SARS-CoV-2 inactivated vaccines in SLE patients compared to healthy controls. A post-vaccination cross-sectional survey was conducted in 188 patients with SLE and in 190 healthy controls who had received at least one dose of SARS-CoV-2 inactivated vaccine to find out post-vaccination adverse event (AE) or SLE flares. A total of 188 patients with SLE and 190 healthy controls vaccinated with the two-dose regimen SARS-CoV-2 inactivated vaccine were enrolled in the study. The two groups were matched in age, sex, medical background, income, and education level. All the SLE patients were in disease remission or with low disease activity with a median age of 35 years, a sex constituent ratio of 87.4% female, and a median disease duration of 4 years. SLE patients had much more concerns about vaccination safety (44.7% vs. 15.8%, P < 0.001), and were much less willing to get vaccinated (57.4% vs. 88.4%, P < 0.001). SLE patients had more mild adverse events after the first vaccine dose (43.6% vs. 25.3%, P = 0.008), and less mild adverse events after the second vaccine dose (19.8% vs. 34.9%, P = 0.024), compared with healthy controls. The AEs were minor and there were no serious or major adverse events in both groups. In patients with SLE, the post-vaccination disease activity remained stable. One previously undiagnosed female progressed into symptomatic SLE after one week of vaccination. Although SLE patients had concerns about the safety of the SARS-CoV-2 vaccines, the inactivated vaccination was safe in patients with stable SLE.

The first imported case of monkeypox in Taiwan.

he first imported case of monkeypox in Taiwan was diagnosed in an Asian man with HIV-1 infection and asymptomatic COVID-19, returning from Germany. Atypical presentations included asynchronous skin lesions, anogenital lesions and prominent inguinal lymphadenopathy. Whole genomic sequence alignment indicate that the Taiwan strain clustered together with human monkeypox virus West African clade B.1, currently circulating in Europe. Prompt diagnosis and infection control measures are crucial to mitigate the spread of monkeypox.

Varicella zoster virus reactivation following COVID-19 vaccination in patients with autoimmune inflammatory rheumatic diseases: A cross-sectional Chinese study of 318 cases.

Recently, varicella-zoster virus (VZV) reactivation has been observed after the administration of coronavirus disease 2019 (COVID-19) vaccines. Autoimmune inflammatory rheumatic diseases (AIIRDs) patients are at a higher risk for VZV reactivation for immunocompromised status. The study aimed to investigate the adverse events (AEs), especially VZV reactivation, following vaccination against  severe acute respiratory syndrome coronavirus-2 in a Chinese cohort of AIIRD patients. A cross-sectional survey using an online questionnaire was conducted among AIIRD patients and healthy controls (HCs). Multivariate logistic regression was used to identify potential factors associated with VZV reactivation. 318 AIIRD patients and 318 age and sex-matched HCs who got COVID-19 inactivated vaccines were recruited. The main AIIRDs are rheumatoid arthritis (31.8%) and systemic lupus erythematous (23.9%). Most of patients (85.5%) had stable disease and 13.2% of them had aggravation after vaccination. Compared to HCs, patients had higher rates of rash (p = 0.001), arthralgia (p < 0.001) and insomnia (p = 0.007). In addition, there were 6 (1.9%) AIIRD patients and 5 (1.6%) HCs reported VZV reactivation after the COVID-19 vaccination (p = 0.761). Multivariate logistic regression analysis illustrated that diabetes mellitus (odd ratio [OR], 20.69; 95% confidence interval [CI], 1.08-396.79; p = 0.044), chronic hepatitis B virus infection (OR, 24.34; 95% CI, 1.27-466.74; p = 0.034), and mycophenolate mofetil (OR, 40.61; 95% CI, 3.33-496.15; p = 0.004) independently identified patients with VZV reactivation. Our findings showed that the inactivated COVID-19 vaccination was safe for AIIRD patients though some patients could suffer from VZV reactivation.

Individual bat viromes reveal the co-infection, spillover and emergence risk of potential zoonotic viruses (preprint)

Bats are reservoir hosts for many zoonotic viruses. Despite this, relatively little is known about the diversity and abundance of viruses within bats at the level of individual animals, and hence the frequency of virus co-infection and inter-species transmission. Using an unbiased meta-transcriptomics approach we characterised the mammalian associated viruses present in 149 individual bats sampled from Yunnan province, China. This revealed a high frequency of virus co-infection and species spillover among the animals studied, with 12 viruses shared among different bat species, which in turn facilitates virus recombination and reassortment. Of note, we identified five viral species that are likely to be pathogenic to humans or livestock, including a novel recombinant SARS-like coronavirus that is closely related to both SARS-CoV-2 and SARS-CoV, with only five amino acid differences between its receptor-binding domain sequence and that of the earliest sequences of SARS-CoV-2. Functional analysis predicts that this recombinant coronavirus can utilize the human ACE2 receptor such that it is likely to be of high zoonotic risk. Our study highlights the common occurrence of inter-species transmission and co-infection of bat viruses, as well as their implications for virus emergence.

Implementation of Web-Based Dynamic Assessments as Sustainable Educational Technique for Enhancing Reading Strategies in English Class during the COVID-19 Pandemic

The COVID-19 pandemic has resulted in educational disruption at a global scale. Based on the United Nation’s Sustainable Development Goal 4, “achieving inclusive and quality education for all”, this study designed two feasible learning models for the solution of sustainable learning during the COVID-19 pandemic, GPAM-WATA and Paper-and-Pencil test (PPT). The GPAM-WATA, a web-based dynamic assessment, offers online learning to most of the populations impacted by the COVID-19 pandemic, while PPT makes the vulnerable groups’ access to learning possible with the aid of paper-based delivery. A quasi-experimental design was adopted, and both learning models were applied to a junior high school English reading course in Taiwan. A total of 122 seventh graders were randomly assigned to the GPAM-WATA group and PPT group for self-directed learning. The findings show that the GPAM-WATA is a sustainable educational technique that facilitates a better improvement in English reading performance. The PPT also has a positive effect on English reading performance, although not significantly if compared with the GPAM-WATA. This study suggests that GPAM-WATA is effective for English reading instruction in an online learning environment. The PPT can be an alternative approach for students stuck without access to online delivery during the COVID-19 pandemic.

Mental health and preventive behaviour of pregnant women in China during the early phase of the COVID-19 period.

BACKGROUND: The COVID-19 has caused significant toll over the globe. Pregnant women are at risk of infection. The present study examined the frequency of washing hands with soap and wearing face mask when going out, prevalence of depression and anxiety, and identified their associated factors among pregnant women during the early phase of COVID-19 outbreak in China. METHODS: A cross-sectional online survey was conducted between 24 February and 3 March 2020. A total of 15 428 pregnant women who were using maternal health care services in China completed a questionnaire which assessed their socio-demographic and pregnancy-related characteristics, contextual, cognitive and social factors related to COVID-19, frequency of washing hands and wearing face masks, and depression and anxiety. Logistics regression analyses were performed to identify the associated factors of preventive behaviours and mental health. RESULTS: The prevalence of probable anxiety and depression was 28.2% and 43.6% respectively. 19.8% reported always wearing face mask when going out, and 19.1% reported washing hands with soap for more than 10 times per day. Results from logistic regression analyses showed that older age was associated with lower levels of depression and anxiety (OR = 0.42-0.67) and higher frequency of washing hands (OR = 1.57-3.40). Higher level of education level was associated with probable depression (OR = 1.31-1.45) and higher frequency of wearing face mask (OR = 1.50-1.57). After adjusting for significant socio-demographic and pregnancy-related factors, place of residence being locked down (aOR = 1.10-1.11), being quarantined (aOR = 1.42-1.57), personally knowing someone being infected with COVID-19 (aOR = 1.80-1.92), perception that COVID-19 would pose long term physical harm to human (aOR = 1.25-1.28) were associated with higher levels of depression and anxiety, while the perception that the disease will be under control in the coming month was associated with lower levels of depression and anxiety (aOR = 0.59-0.63) and lower tendency of always wearing face mask (aOR = 0.85). Social support was associated with lower levels of depression and anxiety (aOR = 0.86-0,87) and higher frequency of washing hands (aOR = 1.06). CONCLUSIONS: The mental health and preventive behaviours of pregnant women during COVID-19 outbreak was associated with a range of socio-demographic, pregnancy-related, contextual, cognitive and social factors. Interventions to mitigate their mental health problems and to promote preventive behaviours are highly warranted.

[Challenges to the Nursing Practicum During the COVID-19 Pandemic].

The COVID-19 pandemic has greatly impacted first-line medical staff as well as nursing-student clinical practicum programs. How to cooperate with the government's pandemic-prevention policies and reduce the gap between education and clinical practice represent significant challenges. In this paper, Chang Gung University of Science and Technology (CCUST) is used as an example to show how schools in Taiwan have effectively adapted the fundamentals of nursing practicum programs to the current pandemic using e-learning, group discussions, case analysis, clinical skill practice, and clinical case simulation scenario exercises. The program at CCUST both takes into account the safety of students and has achieved all critical nursing practice goals. After implementation of these adjustments, satisfaction among nursing students with the practicum environment and the clinical instructors was found to be significantly higher for the on-campus clinical practicum than for the off-campus clinical practicum. Furthermore, the results of qualitative data analyses show that nursing students in the on-campus practicum gained significant knowledge and experience and commented positively on their experience. For example, the students indicated that they were satisfied with the simulated clinical environment of the CCC, the teaching strategies and adaptability of the instructor, and the application of virtual reality scenario cases to enhance skill proficiency and learning outcomes. The adjusted nursing clinical practicum described in this paper may be used as a reference to ensure the quality of nursing clinical practicum programs is maintained during epidemics.

Organizing pneumonia of COVID-19: Time-dependent evolution and outcome in CT findings.

BACKGROUND: As a pandemic, a most-common pattern resembled organizing pneumonia (OP) has been identified by CT findings in novel coronavirus disease (COVID-19). We aimed to delineate the evolution of CT findings and outcome in OP of COVID-19. MATERIALS AND METHODS: 106 COVID-19 patients with OP based on CT findings were retrospectively included and categorized into non-severe (mild/common) and severe (severe/critical) groups. CT features including lobar distribution, presence of ground glass opacities (GGO), consolidation, linear opacities and total severity CT score were evaluated at three time intervals from symptom-onset to CT scan (day 0-7, day 8-14, day > 14). Discharge or adverse outcome (admission to ICU or death), and pulmonary sequelae (complete absorption or lesion residuals) on CT after discharge were analyzed based on the CT features at different time interval. RESULTS: 79 (74.5%) patients were non-severe and 103 (97.2%) were discharged at median day 25 (range, day 8-50) after symptom-onset. Of 67 patients with revisit CT at 2-4 weeks after discharge, 20 (29.9%) had complete absorption of lesions at median day 38 (range, day 30-53) after symptom-onset. Significant differences between complete absorption and residuals groups were found in percentages of consolidation (1.5% vs. 13.8%, P = 0.010), number of involved lobe > 3 (40.0% vs. 72.5%, P = 0.030), CT score > 4 (20.0% vs. 65.0%, P = 0.010) at day 8-14. CONCLUSION: Most OP cases had good prognosis. Approximately one-third of cases had complete absorption of lesions during 1-2 months after symptom-onset while those with increased frequency of consolidation, number of involved lobe > 3, and CT score > 4 at week 2 after symptom-onset may indicate lesion residuals on CT.

A Pattern Categorization of CT Findings to Predict Outcome of COVID-19 Pneumonia.

Background: As global healthcare system is overwhelmed by novel coronavirus disease (COVID-19), early identification of risks of adverse outcomes becomes the key to optimize management and improve survival. This study aimed to provide a CT-based pattern categorization to predict outcome of COVID-19 pneumonia. Methods: One hundred and sixty-five patients with COVID-19 (91 men, 4-89 years) underwent chest CT were retrospectively enrolled. CT findings were categorized as Pattern 0 (negative), Pattern 1 (bronchopneumonia pattern), Pattern 2 (organizing pneumonia pattern), Pattern 3 (progressive organizing pneumonia pattern), and Pattern 4 (diffuse alveolar damage pattern). Clinical findings were compared across different categories. Time-dependent progression of CT patterns and correlations with clinical outcomes, i.e." discharge or adverse outcome (admission to ICU, requiring mechanical ventilation, or death), with pulmonary sequelae (complete absorption or residuals) on CT after discharge were analyzed. Results: Of 94 patients with outcome, 81 (86.2%) were discharged, 3 (3.2%) were admitted to ICU, 4 (4.3%) required mechanical ventilation, 6 (6.4%) died. 31 (38.3%) had complete absorption at median day 37 after symptom onset. Significant differences between pattern-categories were found in age, disease severity, comorbidity and laboratory results (all P < 0.05). Remarkable evolution was observed in Pattern 0-2 and Pattern 3-4 within 3 and 2 weeks after symptom-onset, respectively; most of patterns remained thereafter. After controlling for age, CT pattern significantly correlated with adverse outcomes [Pattern 4 vs. Pattern 0-3 [reference]; hazard-ratio [95% CI], 18.90 [1.91-186.60], P = 0.012]. CT pattern [Pattern 3-4 vs. Pattern 0-2 [reference]; 0.26 [0.08-0.88], P = 0.030] and C-reactive protein [>10 vs. ≤ 10 mg/L [reference]; 0.31 [0.13-0.72], P = 0.006] were risk factors associated with pulmonary residuals. Conclusion: CT pattern categorization allied with clinical characteristics within 2 weeks after symptom onset would facilitate early prognostic stratification in COVID-19 pneumonia.

Neutrophil to lymphocyte ratio as prognostic and predictive factor in patients with coronavirus disease 2019: A retrospective cross-sectional study.

This retrospective study was designed to explore whether neutrophil to lymphocyte ratio (NLR) is a prognostic factor in patients with coronavirus disease 2019 (COVID-19). A cohort of patients with COVID-19 admitted to the Tongren Hospital of Wuhan University from 11 January 2020 to 3 March 2020 was retrospectively analyzed. Patients with hematologic malignancy were excluded. The NLR was calculated by dividing the neutrophil count by the lymphocyte count. NLR values were measured at the time of admission. The primary outcome was all-cause in-hospital mortality. A multivariate logistic analysis was performed. A total of 1004 patients with COVID-19 were included in this study. The mortality rate was 4.0% (40 cases). The median age of nonsurvivors (68 years) was significantly older than survivors (62 years). Male sex was more predominant in nonsurvival group (27; 67.5%) than in the survival group (466; 48.3%). NLR value of nonsurvival group (median: 49.06; interquartile range [IQR]: 25.71-69.70) was higher than that of survival group (median: 4.11; IQR: 2.44-8.12; P < .001). In multivariate logistic regression analysis, after adjusting for confounding factors, NLR more than 11.75 was significantly correlated with all-cause in-hospital mortality (odds ratio = 44.351; 95% confidence interval = 4.627-425.088). These results suggest that the NLR at hospital admission is associated with in-hospital mortality among patients with COVID-19. Therefore, the NLR appears to be a significant prognostic biomarker of outcomes in critically ill patients with COVID-19. However, further investigation is needed to validate this relationship with data collected prospectively.

Evolution of CT findings in patients with mild COVID-19 pneumonia.

OBJECTIVES: To delineate the evolution of CT findings in patients with mild COVID-19 pneumonia. METHODS: CT images and medical records of 88 patients with confirmed mild COVID-19 pneumonia, a baseline CT, and at least one follow-up CT were retrospectively reviewed. CT features including lobar distribution and presence of ground glass opacities (GGO), consolidation, and linear opacities were analyzed on per-patient basis during each of five time intervals spanning the 3 weeks after disease onset. Total severity scores were calculated. RESULTS: Of patients, 85.2% had travel history to Wuhan or known contact with infected individuals. The most common symptoms were fever (84.1%) and cough (56.8%). The baseline CT was obtained on average 5 days from symptom onset. Four patients (4.5%) had negative initial CT. Significant differences were found among the time intervals in the proportion of pulmonary lesions that are (1) pure GGO, (2) mixed attenuation, (3) mixed attenuation with linear opacities, (4) consolidation with linear opacities, and (5) pure consolidation. The majority of patients had involvement of ≥ 3 lobes. Bilateral involvement was more prevalent than unilateral involvement. The proportions of patients observed to have pure GGO or GGO and consolidation decreased over time while the proportion of patients with GGO and linear opacities increased. Total severity score showed an increasing trend in the first 2 weeks. CONCLUSIONS: While bilateral GGO are predominant features, CT findings changed during different time intervals in the 3 weeks after symptom onset in patients with COVID-19. KEY POINTS: • Four of 88 (4.5%) patients with COVID-19 had negative initial CT. • Majority of COVID-19 patients had abnormal CT findings in ≥ 3 lobes. • A proportion of patients with pure ground glass opacities decreased over the 3 weeks after symptom onset.
