ABSTRACT

To enhance students' learning motivation and learning interest, scholars have attempted to incorporate game-based learning (GBL) into courses to improve conventional teaching which is mostly carried out using textbooks, presentations, or videos. However, one-tier tests were mainly adopted in previous GBL, meaning that it was difficult to identify whether students answered questions correctly by understanding knowledge or merely guessed the correct answer. Such tests also make it difficult to provide adequate feedback and guidance during the learning process. In order to solve this problem, a two-tier test-based digital gaming approach (TT-DGA) developed using RPG Maker was proposed in this study. It not only provided students with a more interesting way to learn art and view world-famous artworks in the game, but also introduced a two-tier test in the learning process to help students gradually construct professional art appreciation knowledge. To explore the effects of this approach, a total of 62 university students who took an elective art course were recruited in the current study. A quasi-experimental design was employed and the course was conducted physically during the Covid-19 pandemic. One class was the experimental group which adopted the TT-DGA for learning, while the other class was the control group which adopted the conventional gaming approach (C-DGA). The results showed that the TT-DGA could significantly enhance students' learning achievement of art appreciation, learning motivation, learning attitudes, and flow experience. Based on the behavioral analysis, students in the experimental group were more active than those in the control group in terms of reading art history materials, watching videos, engaging in tests, and playing the game again. Finally, the interview results uncovered that the two-tier test could help students conduct self-inspection, confirm the accuracy of their understandings of knowledge, and correct misconceptions, and that DGBL made the art course more interesting. • A two-tier test-based digital gaming approach for art education is proposed. • An educational computer game was developed based on the proposed approach. • The approach improved students' learning achievement of art appreciation. • The approach improved students' learning motivation. • The approach improved students' self-inspection and accuracy art concepts.

ABSTRACT

Although real-time reverse transcriptase polymerase chain reaction (real-time RT-PCR) remains as a golden standard for detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, it can not be easily expanded to large-scaled screening during outbreaks, and the positive results do not necessarily correlate with infectious status of the identified subjects. In this study, the performance of Vstrip® RV2 COVID-19 Antigen Rapid Test (RAT) and its correlation with virus infectivity was examined by virus culture using 163 sequential respiratory specimens collected from 26 SARS-CoV-2 infected patients. When the presence of cytopathic effects (CPE) in cell culture was used as a reference method for virus infectivity, the sensitivity, specificity and accuracy of Vstrip® RV2 COVID-19 Antigen Rapid Test was 96.43%, 89.63%, and 90.8%, respectively. The highest Ct value was 27.7 for RdRp gene and 25.79 for E gene within CPE-positive samples, and the highest Ct value was 31.9 for RdRp gene and 29.1 for E gene within RAT positive samples. When the Ct values of specimens were below 25, the CPE and RAT results had high degree of consistency. We concluded that the RAT could be a great alternative method for determining the infectious potential of individuals with high viral load.

ABSTRACT

Introduction: Coronavirus disease-2019 (COVID-19) has affected more than 608 million people and has killed 6.5 million people in the world. A few studies showed traditional Chinese medicine can be beneficial for COVID-19 treatment. An herbal preparation Jin Si Herbal Tea (JS) was formulated with herbal extracts known for their potential to decrease spike protein and ACE2 interaction, 3CL, and TRPMSS2 protease activity, and thus aimed to evaluate the clinical course of JS co-treatment along with the usual treatment schedule given for severe COVID-19 patients. Methods: This retrospective cohort study included patients with severe COVID-19 admitted to Hualien Tzu Chi Hospital between June and July 2021. All the patients were co-treated with JS and the primary outcome was death. The secondary outcomes included laboratory exam, Ct value, clinical course, and hospital stays. There were 10 patients recruited in this study and divided into < 70 years and ≧ 70 years groups (n = 5 in each group). Results: Older patients (≧70 years) had a higher Charlson Comorbidity Index, VACO index, and lower hemoglobin levels than < 70 years patients. The trend of lymphocyte count, LDH, D-dimer, and Ct value of non-survivors was not consistent with previous studies. The death rate was 20% and the recovery rate to mild illness in 14 days was 40%. Conclusion: In conclusion, this is the first clinical study of JS co-treatment in severe COVID-19 patients. JS co-treatment might reduce death rate and recovery time. Further large-scale clinical trials would be expected.

ABSTRACT

BACKGROUND AND OBJECTIVE: Recent advances have led to cure or long-term disease control for patients with hematological malignancy (HM). Unfortunately, some of them still have poor prognoses and are often associated with significant symptom burden and poor quality of life for patients and families. These patients usually require supportive care including red blood cell and platelet transfusion, due to disease itself and the oncological treatment, apart from their symptom management. However, there is currently lack of the literatures review in these aspects. The objective of this review is to summarize practical supportive care recommendations for physicians or nurses practicing in palliative care (PC)/hematology-oncology unit, starting with core approaches in use of blood products for anemia and thrombocytopenia, management of tumor lysis syndrome, PC and oncology nursing care. METHODS: Evidence for this review was obtained from a search of the Cochrane database, PubMed, guidelines of European Society of Medical Oncology, British society of Hematology, American Society of Clinical Oncology, National Comprehensive Cancer Network and peer-reviewed journal articles. KEY CONTENT AND FINDINGS: For asymptomatic cancer patients who are anaemic, a threshold of haemoglobin level of 7 g/dL is considered to be safe and generally favored for blood transfusion. 'Single-unit' red cell transfusion is safer and at least as effective as 'double-unit' transfusion. Prophylactic platelet transfusion should be given to stable patients without bleeding and with platelet count less than 10×109/L. In febrile patients, the threshold is lifted to 20×109/L. There are also recommendations for the use of blood products during COVID-19 pandemic. In general, HM patients were more prone to painful infections when compared with solid cancer patients. Thus, antibiotics to treat underlying infections should be applied whenever possible and as required to control pain. CONCLUSIONS: This narrative review showed the recent literatures in the supportive care and symptom management of advanced HM patients. However, it is limited by some of the 'evidence-based' recommendations for interventions (including symptom management) based on early phase of HM populations rather than those receiving end-of-life care.

ABSTRACT

BACKGROUND: This study aims to explore differences of psychological impact and influencing factors that affected Taiwanese healthcare workers (HCW) during the first and second wave of COVID-19. METHODS: a cross sectional survey of first-line HCW during November 2021 to February 2022: 270 paper questionnaires were issued and the valid response rate was 86% (231). For statistical analysis, descriptive statistics, Pearson correlation, and multivariate linear regression were used. RESULTS: regardless of the wave of the pandemic, nearly 70% of HCW had anxiety, nearly 60% felt depressed, half of them suffered from insomnia, and one in three felt insufficient social support, which means a high level of loneliness. With an increased number of infected patients during the second wave, HCW felt significant changes of workload and schedule, with higher concern over risk of infection, and these factors induced higher levels of anxiety, but they manifested better satisfaction over public health policies and information provided by hospitals and governments. Changes of working schedules or duties positively relate to levels of anxiety and insomnia. The risk of infection causes anxiety, depression, and insomnia. Workplace relationships significantly relate to depression and loneliness. A negative family support causes an adverse psychological impact. CONCLUSIONS: the pandemic has a negative psychological impact on HCW. Early recognition of significant influencing factors, providing psychological support and therapy, are helpful strategies for reducing the adverse psychological effects.

ABSTRACT

Background: Gut microbiota can be associated with COVID-19 vaccine immunogenicity. We investigated whether recent antibiotic use influences BNT162b2 vaccine immunogenicity. Methods: BNT162b2 recipients from three centers were prospectively recruited. Outcomes of interest were seroconversion of neutralising antibody (NAb) at day 21, 56 and 180 after first dose. We calculated the adjusted odds ratio (aOR) of seroconversion with antibiotic usage (defined as ever use of any antibiotics within six months before first dose of vaccine) by adjusting for covariates including age, sex, smoking, alcohol, and comorbidities. Results: Of 316 BNT162b2 recipients (100 [31.6%] male; median age: 50.1 [IQR: 40.0-57.0] years) recruited, 29 (9.2%) were antibiotic users. There was a trend of lower seroconversion rates in antibiotic users than non-users at day 21 (82.8% vs. 91.3%; p = 0.14) and day 56 (96.6% vs. 99.3%; p = 0.15), but not at day 180 (93.3% vs. 94.1%). A multivariate analysis showed that recent antibiotic usage was associated with a lower seroconversion rate at day 21 (aOR 0.26;95% CI: 0.08-0.96). Other factors associated with a lower seroconversion rate after first dose of the BNT162b2 vaccine included age ≥ 60 years (aOR: 0.34;95% CI: 0.13-0.95) and male sex (aOR: 0.14, 95% CI: 0.05-0.34). There were no significant factors associated with seroconversion after two doses of BNT16b2, including antibiotic use (aOR: 0.03;95% CI: 0.001-1.15). Conclusions: Recent antibiotic use may be associated with a lower seroconversion rate at day 21 (but not day 56 or 180) among BNT162b2 recipients. Further long-term follow-up data with a larger sample size is needed to reach a definite conclusion on how antibiotics influence immunogenicity and the durability of the vaccine response.

ABSTRACT

Rapid development and deployment of vaccines is crucial to control the continuously evolving COVID-19 pandemic. The placebo-controlled phase 3 efficacy trial is still the standard for authorizing vaccines in the majority of the world. However, due to a lack of eligible participants in parts of the world, this has not always been feasible. Recently, the Taiwan Food and Drug Administration, following the consensus of the International Coalition of Medicines Regulatory Authorities (ICMRA), adopted the use of immunobridging studies as acceptable for authorizing COVID-19 vaccines in lieu of efficacy data. Here, we describe a study in which our candidate vaccine, MVC-COV1901, an adjuvanted protein subunit vaccine, has been granted emergency use authorization (EUA) in Taiwan based on a noninferiority immunobridging study. Immunogenicity results from the per protocol immunogenicity (PPI) subset (n = 903) from the MVC-COV1901 phase 2 trial were compared with results from 200 subjects who had received an adenovirus vector vaccine, AstraZeneca ChAdOx nCOV-19 (AZD1222), in a separate study. The lower bound of the 95% confidence interval (CI) of the geometric mean titer (GMT) ratio comparing MVC-COV1901 to AZD1222 was 3.4. The lower bound of the 95% CI of the sero-response rate was 95.5%. Both the GMT ratio and sero-response rate exceeded the criteria established by the Taiwan regulatory authority, leading to EUA approval of MVC-COV1901 in Taiwan.

ABSTRACT

Background Rapid development and deployment of vaccine is crucial to control the continuously evolving COVID-19 pandemic. Placebo-controlled phase 3 efficacy trial is still standard for authorizing vaccines in majority of the world. However, due to lack of cases or participants in parts of the world, this has not always been feasible. An alternative to efficacy trial is immunobridging, in which the immune response or correlates of protection of a vaccine candidate is compared against an approved vaccine. Here we describe a case study where our candidate vaccine, MVC-COV1901, has been granted for emergency use authorization (EUA) locally based on the non-inferiority immunobridging process. Methods The per protocol immunogenicity (PPI) subset from the MVC-COV1901 phase 2 trial was used for this study and consisted of 903 subjects who have received two doses of MVC-COV1901 as scheduled in the clinical trial. The comparator set of population consisted of 200 subjects of [≥] 20 years of age who were generally healthy, and have received two doses of AstraZeneca ChAdOx nCOV-19 (AZD1222) recruited from Taoyuan General Hospital, Ministry of Health and Welfare. Results MVC-COV1901 was shown to have a geometric mean titer (GMT) ratio lower bound 95% confidence internal (CI) of 3.4 against the comparator vaccine and a seroconversion rate of 95.5% at the 95% CI lower bound, which both exceeded the criteria set by the Taiwan regulatory authority for EUA approval. These results supported the EUA approval of MVC-COV1901 by the Taiwanese regulatory authority in July 2021. Following the consensus of the International Coalition of Medicines Regulatory Authorities (ICMRA), countries from the Access Consortium has recently adopted the use of immunobridging studies as acceptable for authorizing COVID-19 vaccines in lieu of efficacy data. Conclusion The data presented in the study showed that it is reasonably likely that the vaccine efficacy of MVC-COV1901 is similar or superior to that of AZ. Data could be used in support of further vaccine development and regulatory approval.

ABSTRACT

To discover the new medical entity from edible marine algae, our continuously natural product investigation focused on endophytes from marine macroalgae Grateloupia sp. Two new azaphilones, 8a-epi-hypocrellone A (1), 8a-epi-eupenicilazaphilone C (2), together with five known azaphilones, hypocrellone A (3), eupenicilazaphilone C (4), ((1E,3E)-3,5-dimethylhepta-1,3-dien-1-yl)-2,4-dihydroxy-3-methylbenzaldehyde (5), sclerotiorin (6), and isochromophilone IV (7) were isolated from the alga-derived fungus Penicillium sclerotiorum. The structures of isolated azaphilones (1-7) were elucidated by spectrometric identification, especially HRESIMS, CD, and NMR data analyses. Concerning bioactivity, cytotoxic, anti-inflammatory, and anti-fibrosis activities of those isolates were evaluated. As a result, compound 1 showed selective toxicity toward neuroblastoma cell line SH-SY5Y among seven cancer and one fibroblast cell lines. 20 µM of compounds 1, 3, and 7 inhibited the TNF-α-induced NFκB phosphorylation but did not change the NFκB activity. Compounds 2 and 6 respectively promoted and inhibited SMAD-mediated transcriptional activities stimulated by TGF-ß.

ABSTRACT

Rationale: Patients with asthma were advised to avoid coronavirus disease (COVID-19) and comply with medication during the COVID-19 pandemic. Respiratory tract infection is a common cause of asthma exacerbations. There has not been evidence suggesting the link between COVID-19 and asthma exacerbation, especially in places with dramatic responses in infection control with universal masking and aggressive social distancing. Objectives: To assess the number for admissions of asthma exacerbations in January to April 2020 in Hong Kong with reference to admission in the past 5 years. Methods: Admission records of asthma exacerbations were retrieved from the Clinical Data Analysis and Reporting System. Patients aged 18 years or older with a known history of asthma admitted for asthma exacerbation were included. Log-linear was used to model count, with year and masking used as covariate and further analysis on ambient temperature and length of hospital stays. Fisher's exact test was used to compare the mortality rate and mechanical ventilation between the periods. Admissions for myocardial infarction, ischemic stroke, and gastric ulcer were included as controls. Results: The number of admissions for asthma exacerbations significantly decreased by 53.2% (95% confidence interval [CI], 50.4-55.8%) in 2020 compared with monthly average admission in 2015-2019, with a higher magnitude of decrease compared with control diagnoses. Admissions for asthma exacerbations decreased by 2.0% (95% CI, 1.8-2.2%) with every 1°C (1.8°F) increase in temperature and by 0.8% with every 1% increase in masking (95% CI, 0.8-0.9%). Conclusions: Hospitalization number for asthma exacerbations significantly decreased in early 2020, with similar length of stay. This was observed with concomitant practice of universal masking and social distancing during the COVID-19 pandemic in Hong Kong. We proposed that universal masking and social distancing reduced respiratory viral infection, leading to fewer hospital admissions for asthma exacerbations.

ABSTRACT

Family medicine physicians have been on the front lines of the novel coronavirus disease 2019 (COVID-19) pandemic; however, research and publications in family medicine journals are rarely discussed. In this study, a bibliometric analysis was conducted on COVID-19-related articles published in PubMed-indexed English language family medicine journals in 2020, which recorded the publication date and author's country and collected citations from Google Scholar. Additionally, we used LitCovid (an open database of COVID-19 literature from PubMed) to determine the content categories of each article and total number of global publications. We found that 33 family medicine journals published 5107 articles in 2020, of which 409 (8.0%) were COVID-19-related articles. Among the article categories, 107 were original articles, accounting for only 26.2% of the articles. In terms of content, the main category was prevention, with 177 articles, accounting for 43.3% of the articles. At the beginning of the epidemic, 10 articles were published in family medicine journals in January 2020, accounting for 11% of all COVID-19-related articles worldwide; however, this accounted for <0.5% of all disciplinary studies in the entire year. Therefore, family medicine journals indeed play a sentinel role, and the intensities and timeliness of COVID-19 publications deserve further investigation.

ABSTRACT

BACKGROUND: Global pandemic resulted from the coronavirus disease-19 (COVID-19) demands mental health concerns on the affected population. We examine the time-course shift of psychological burden among suspected and confirmed COVID-19 patients. METHODS: Participants with suspected or confirmed COVID-19 were included in the cohort. Consecutive surveys were conducted upon hospital admission, discharge, and during outpatient follow-up by adapting the 5-item brief symptom rating scale (BSRS-5) assessing psychological symptoms including anxiety, depression, hostility, interpersonal sensitivity, and insomnia. The sixth measure to observe suicidal ideation was also included. RESULTS: A total of 109 eligible patients participated in the study, in which 83.49% reported no distress upon hospital admission, while 2.75%, 3.66%, and 10.1% patients were assessed as being with severe, moderate and mild psychological distress, respectively. Overall, age, sex, and history of contact did not significantly differ between patients with and without psychological distress. Multivariate logistic regression revealed that patients admitted during April-May (OR: 7.66, 95% CI: 1.46-40.28) and presented with symptoms including sore throat (OR: 4.24, 95% CI: 1.17-15.29) and malaise (OR: 5.24, 95% CI: 1.21-22.77) showed significantly higher risk of psychological distress. Cough symptom interestingly showed lower risk of emotional distress (OR: 0.25, 95% CI: 0.08-0.81). Subsequent surveys upon hospital discharge and during outpatient follow-up revealed steadily declining distress among all cohort. CONCLUSION: At least 16.5% of our cohort reported psychological distress upon hospital admission, with distinct time-dependent decline. Access to mental health support, alongside with promoting positive activities for good mental health are pivotal for those directly affected.

ABSTRACT

The COVID-19 pandemic was caused by SARS-CoV-2 infection. To prevent the spread of SARS-CoV-2, an effective vaccine is required. Two linear peptides from potential B-cell epitopes in the spike protein of SARS-CoV-2 (a.a. 440-460; a.a. 494-506) were synthesized and used to immunize rabbits. High-titer antibodies of IgG were produced, purified, and verified by Western blot analysis. Antibodies against these two epitopes could effectively neutralize SARS-CoV-2 pseudoviral particles with the spike proteins from not only the original strain (basal; wild-type), but also a strain with a single point mutation (D614G), and two other emerging variants (the Alpha and Beta variants) prevalent around the world, but not from SARS-CoV. In conclusion, antibodies against these two epitopes are protective. This information is important for the development of vaccines against SARS-CoV-2.

ABSTRACT

OBJECTIVES: Severe acute respiratory syndrome coronavirus 2 infections commonly lead to respiratory failure and potentially fatal systemic inflammation and organ failure. Nebulized DAS181, a host-directed biologics with sialidase activity, is an investigational drug with antiviral activities on parainfluenza and influenza under phase 3 and phase 2 development. The objective of this study (NCT04324489) is to investigate the safety and effects of nebulized DAS181 on hypoxic coronavirus disease 2019 patients. DESIGN: Single-center, prospective, open-label, compassionate use. SETTING: Renmin Hospital of Wuhan University, Department of Respiratory and Critical Care Medicine and Department of Infectious Diseases. SUBJECTS: Patients 18 to 70 years old who met Chinese criteria for severe coronavirus disease 2019 pneumonia and required supplemental oxygen but not on mechanical ventilator at screening. INTERVENTIONS: Nebulized DAS181 (4.5 mg) twice a day for 10 days. MEASUREMENTS AND MAIN RESULTS: Three male coronavirus disease 2019 hypoxic patients with bilateral lung involvement completed DAS181 treatment for 10 days. By day 14, all achieved return to room air (primary endpoint) and their nasopharyngeal swabs were negative for severe acute respiratory syndrome coronavirus 2. Clinical severity improved from severe coronavirus disease 2019 at baseline to moderate or mild disease by day 5, consistent with rapid reduction of inflammatory cytokines by days 2-3 and radiologic improvement by days 5-10. No DAS181-related adverse events were reported. CONCLUSIONS: Inhalation of DAS181 was well tolerated and potential clinical benefit of DAS181 on hypoxic coronavirus disease 2019 is the reduction of supplemental oxygen need. Efficacy and safety, including pharmacokinetics and viral studies of DAS181 in severe, hypoxic coronavirus disease 2019, should be examined by a double-blind, randomized controlled study.

ABSTRACT

BACKGROUND: Brugada syndrome (BrS) is a rare inherited disease causing sudden cardiac death (SCD). Copy number variants (CNVs) can contribute to disease susceptibility, but their role in Brugada syndrome (BrS) is unknown. We aimed to identify a CNV associated with BrS and elucidated its clinical implications. METHODS: We enrolled 335 unrelated BrS patients from 2000 to 2018 in the Taiwanese population. Microarray and exome sequencing were used for discovery phase whereas Sanger sequencing was used for the validation phase. HEK cells and zebrafish were used to characterize the function of the CNV variant. FINDINGS: A copy number deletion of GSTM3 (chr1:109737011-109737301, hg38) containing the eighth exon and the transcription stop codon was observed in 23.9% of BrS patients versus 0.8% of 15,829 controls in Taiwan Biobank (P <0.001), and 0% in gnomAD. Co-segregation analysis showed that the co-segregation rate was 20%. Patch clamp experiments showed that in an oxidative stress environment, GSTM3 down-regulation leads to a significant decrease of cardiac sodium channel current amplitude. Ventricular arrhythmia incidence was significantly greater in gstm3 knockout zebrafish at baseline and after flecainide, but was reduced after quinidine, consistent with clinical observations. BrS patients carrying the GSTM3 deletion had higher rates of sudden cardiac arrest and syncope compared to those without (OR: 3.18 (1.77-5.74), P<0.001;OR: 1.76 (1.02-3.05), P = 0.04, respectively). INTERPRETATION: This GSTM3 deletion is frequently observed in BrS patients and is associated with reduced INa, pointing to this as a novel potential genetic modifier/risk predictor for the development of the electrocardiographic and arrhythmic manifestations of BrS. FUNDING: This work was supported by the Ministry of Science and Technology (107-2314-B-002-261-MY3 to J.M.J. Juang), and by grants HL47678, HL138103 and HL152201 from the National Institutes of Health to CA.

ABSTRACT

AIM: The policy enforcing visiting restriction during the COVID-19 pandemic may cause feelings of social isolation among residents in long-term care facilities. This study aimed to explore family members' concerns for their relatives during the lockdown period, assess their level of acceptance of the visiting restriction policy and determine the associated factors. METHODS: From the 156 family members interviewed, demographic data, satisfaction with overall care quality, worry and concerns for their relatives, acceptance of the visiting restriction and arrangement for the residents if cluster infections occur in the facility were recorded. RESULTS: Among the members interviewed, 83 (53.2%) were men; mean age of members was 56.3 ± 9.8; most were offspring of residents in the facility (n = 121, 77.6%), most visited the residents at least once a week (n = 113, 72.4%) before the lockdown. The most common concerns of the family members for their relatives were psychological stress (38.5%), followed by nursing care (26.9%) and daily activity (21.1%). Nearly 84.6% of those interviewed accepted the visiting restriction policy, and a higher satisfaction rating independently associated with acceptance of the visiting restriction policy (odds ratio 2.15). CONCLUSIONS: During the lockdown period, staff members should provide more psychological information about residents to their family members. Higher satisfaction rating was found to be independent of the acceptance of the visiting restriction policy. Therefore, good quality of care of the facility wins the trust of family members, and this might mitigate the tension between the family members and staff during a major crisis.
