The COVID-19 pandemic has plagued the world for over three years since discovering the causative virus, SARS-CoV-2, in China. The rampant spread of the virus led to the loss of livelihoods of millions across the globe. This public health emergency prompted the rapid development of vaccines and treatments to fight against viral infection. Vaccines against the viral infection started rolling out in late 2020, and the distribution of the vaccines worldwide managed to reduce the symptoms of COVID-19 and prevent outbreaks in local communities. However, COVID-19 infections are still prevalent, with patients suffering from severe symptoms which require oxygen support or mechanical ventilation. Thus, therapeutic agents for COVID-19 play a significant role in reducing the risk of disease progression into severe disease and improving hospitalized patients' clinical outcomes. Existing drugs such as remdesivir, molnupiravir, baricitinib, anakinra, and tocilizumab have been repurposed to treat COVID-19 earlier during the pandemic to meet the urgent demand for treatment. There are also novel antiviral and immunomodulating treatments (nirmatrelvir plus ritonavir, ensitrelvir, regdanvimab, sotrovimab, and vilobelimab) that were developed during the pandemic to fight against COVID-19 infections. These therapeutic agents have been reported to be effective and safe for use to treat COVID-19 infections of different severity. Nevertheless, continuous surveillance is imperative in ensuring that these treatment methods maintain efficacy and safety profiles in treating COVID-19 caused by different variants of the virus. © 2023, HH Publisher.

INTRODUCTION: The ChAdOx1 nCoV-19 (ChAd), mRNA-1273 (m1273), MVC-COV1901 (MVC), and BNT162b2 (BNT) COVID-19 vaccines received authorization for emergency use in Taiwan beginning in February 2021. We investigated acute reactions to homologous primary COVID-19 vaccination series in adults aged ≥ 18 years. METHODS: In this prospective observational study based on smartphone data (Taiwan V-Watch), we calculated the frequencies of self-reported local and systemic acute reactions within 7 days of a COVID-19 vaccination, and the health effects up to 3 weeks after each dose. Those who reported adverse reactions after both doses were assessed by the McNemar test. RESULTS: During 22 March 2021-13 December 2021, 77,468 adults were enrolled; 59.0 % were female and 77.8 % were aged 18-49 years. For both doses of all four vaccines, the local and systemic reactions were minor in severity and highest on days 1 and 2 after vaccination, and declined markedly until day 7. For 65,367 participants who provided data after the first and second doses, systemic reactions were more frequent after dose 2 of the BNT and m1273 vaccines (McNemar tests: both p < 0.001), while local reactions were more frequent after dose 2 of the m1273 and MVC vaccines (both p < 0.001), compared with dose 1 of the homologous vaccine. Among the participants aged 18-49 years, the percentage who missed work on the day after vaccination was slightly higher among women (9.3 %) than among men (7.0 %). CONCLUSIONS: Acute reactogenicity and impact of work absenteeism for the four COVID vaccines in the V-Watch survey were mild and of short duration.

During the widespread COVID-19 pandemic, face-to-face teaching was not viable because many schools were forced to close as a preventive measure. Educators abruptly shifted to online classes without sufficient time and resources to prepare for such an enormous transition. Although shifting from traditional face-to-face format to modern e-learning approach ensured that students could be educated outside of the classroom, its impact on the quality of learning and teaching (L&T) can be mixed. This study aims to address the knowledge gap in conventional teacher training by developing a web-based program called T.E.A.C.H. to enhance preservice teachers' psychological and pedagogical competencies for conducting online L&T. The program consisted of five modules, each focused on one dimension of psychological competence (creativity, curiosity, love of learning, judgment, and perspective) and applied to the 'three foci' for online L&T (attendance and participation, engagement, and assessment). Adopting a quasi-experimental design with matched sampling, a total of 314 preservice teachers were allocated into the intervention or control group. The intervention group was given access to the web-based program to receive training materials, learn about the content, and take part in the online L&T exercises. Program effectiveness was evaluated using pretest and posttest questionnaires, a teaching design task, short quizzes, and a program quality assessment. The results showed that the T.E.A.C.H. program was effective in promoting preservice teachers' psychological competencies, positive attitudes toward online L&T, self-efficacy to teach in an online format, intentions to use technology for L&T, and online pedagogical skills. The successful implementation of T.E.A.C.H. encourages school leaders, teachers, and teacher professional development providers to utilize this web-based program to enhance online teaching practices.

OBJECTIVE: To explore the impact of the COVID-19 pandemic on the sleep-wake patterns of preschool children. METHODS: A cohort of preschoolers established before the COVID-19 pandemic was invited to participate in this study. Data including children's demographics, their own and parental sleep-wake patterns, physical activities, and screen time were collected through an online questionnaire from August to September 2020. A comparison was made on the collected data from the same cohort of children before and during the pandemic. RESULTS: The cohort which was established before the pandemic consisted of 3720 preschoolers. For this current study, 642 (17%) participated, and 497 (13%) children who fulfilled the eligibility criteria were included in the final analysis. They showed a delay in their bedtime and wake time on both weekdays and weekends with a 15-30 min increase in nocturnal sleep duration. However, with a reduction in nap time, the average daily sleep duration was shortened by 16.3 ± 64.3 min (p < 0.001) and 27.5 ± 72.9 min (p < 0.001) during weekdays and weekends, respectively. Screen time was increased while outdoor activity duration was decreased. Parental sleep/wake times were also delayed with an increase in sleep duration. Children's sleep habits were associated with screen time and parental sleep/wake patterns. CONCLUSION: Despite school suspension during the COVID-19 pandemic, preschoolers were not sleeping longer. Screen time and parental sleep/wake patterns were the major factors driving the preschoolers' sleep habits. Health education is required to control screen time in children and to promote sleep hygiene among all family members.

Restrictive COVID-19 measures can have significant mental health impacts, particularly on young people. How such measures may influence day-to-day momentary affect, nonetheless, remains to be explored. Experience sampling data were collected from 165 young people (aged 15-24) as part of a larger epidemiological youth mental health study in Hong Kong. We examined the impact of one of the most stringent COVID-19 measures - dine-in restrictions - on momentary positive and negative affect and current contexts and activities of these young people. The effects of a milder form of COVID-19 measure - school suspension - were separately examined. Multilevel analysis revealed that those in the dine-in ban group, compared to dining-as-usual, showed significantly reduced momentary positive affect (ß = -0.17, SE = 0.06, p = 0.003). Its effect remained significant even when accounting for baseline depressive and anxiety symptoms and socioeconomic status (ß = -0.15, SE = 0.05, p = 0.008). The effect of dine-in ban on reduced momentary positive affect was found specifically when participants were in indoor locations (e.g., home, office), alone, and engaged in passive leisure activities. This pattern was not observed when participants were at school or at other outdoor locations, with friends, or engaged in active leisure activities. No significant effect of school suspension on momentary affect was observed. More severe COVID-19 measures, such as dine-in ban, can have significant impacts on the momentary positive affect of young people. Certain contexts and activities may offer protection against the consequences of COVID-19 measures. The current findings may help to inform future designs of mental health interventions and public health policies.
