Learning from the past: Taiwan's responses to COVID-19 versus SARS

Impact of COVID-19 pandemic on neurodevelopmental outcomes of premature infants: a retrospective national cohort study

OBJECTIVE

To compare the neurodevelopmental outcomes of preterm infants before and during the COVID-19 pandemic.

DESIGN

Premature infants born in 2018 were assigned to the pre-pandemic group, while those born in 2019 were assigned to the during-pandemic group.

SETTING

Nationwide cohort study.

PATIENTS

Very low birthweight premature infants registered in the Taiwan Premature Infant Follow-up Network database.

INTERVENTIONS

Anti-epidemic measures, including quarantine and isolation protocols, social distancing, the closure of public spaces and restrictions on travel and gatherings during COVID-19 pandemic.

MAIN OUTCOME MEASURES

Outcomes were measured by Bayley Scales of Infant and Toddler Development Third Edition at corrected ages of 6, 12 and 24 months old. Generalised estimating equation (GEE) was applied to incorporate all measurements into a single model.

RESULTS

Among the 1939 premature infants who were enrolled, 985 developed before the pandemic, while 954 developed during the pandemic. Premature infants whose development occurred during the pandemic exhibited better cognitive composite at the corrected age of 6 months (beta=2.358; 95% CI, 1.07 to 3.65; p<0.001), and motor composite at corrected ages of 12 months (beta=1.680; 95% CI, 0.34 to 3.02; p=0.014). GEE analysis showed that infants who had grown during the pandemic achieved higher scores in cognitive composite (beta=1.416; 95% CI, 0.36 to 2.48; p=0.009).

CONCLUSION

Premature infants in Taiwan who developed during the pandemic showed better neurodevelopment compared with those born before the pandemic.

Depression and anxiety between nurses and nursing assistants working in long-term care facilities during the COVID-19 pandemic

AIM

This study investigated the levels of depression and anxiety in nurses and nursing assistants working in long-term care facilities during the COVID-19 pandemic. We also explored the potential causes of depression and anxiety in nurses and nursing assistants working in long-term care facilities during the pandemic.

BACKGROUND

The COVID-19 pandemic has had a considerable impact on long-term care facilities. The high infection and mortality rates for COVID-19 have resulted in an increased workload for caregivers.

INTRODUCTION

The COVID-19 pandemic exposed caregivers working in long-term care facilities to higher risks of anxiety and depression. Additionally, the high risk of infection in the work environment and concerns about spreading COVID-19 to family members and long-term care facility residents led to various forms of stress among caregivers.

METHODS

The present study was a cross-sectional study. Questionnaires were used to investigate depression and anxiety among regarding nurses and nursing assistants working in long-term care facilities during the pandemic.

RESULTS

The depression and anxiety levels of the nurses were higher than nursing assistants, but had no statistically significant difference (p = 0.551). The factors influencing levels of depression and anxiety in nurses contained facility affiliation and experience working. In terms of nursing assistants, age, marital status, and facility affiliation were correlated with the levels of depression and anxiety.

DISCUSSION

The pandemic has severely impacted caregivers. In the process of implementing pandemic prevention measures and providing care for COVID-19 patients, safeguarding the psychological health of caregivers is also essential.

CONCLUSION

The levels of depression and anxiety in nurses were higher than in nursing assistants working in long-term care facilities during the pandemic.

IMPLICATION FOR NURSING AND HEALTH POLICY

Long-term care facilities managers are recommended to enhance the education and training process for caregivers. Managers are also recommended to ensure provision of sufficient amounts of pandemic prevention equipment and resources.

Association of National Identity and Trust in Government with COVID-19 Vaccination and Brand Choice in Taiwan

In Taiwan, hesitancy regarding COVID-19 vaccination centered more on the choice of vaccine brand than on the decision to vaccinate. However, there is limited research exploring the factors influencing COVID-19 vaccine brand preferences from a sociopolitical perspective. Thus, we aimed to examine how Taiwanese national identity and trust in government influence vaccination status and vaccine brand choice, using longitudinal data from 2020, 2021, and 2023. This study utilized data from the Taiwan Panel Study of Family Dynamics 2020 survey, and combined it with data from two self-administered surveys conducted in 2021 and 2023. We focused on four vaccines commonly administered in Taiwan: AstraZeneca, Moderna, Pfizer-BioNTech, and the domestically-developed Medigen. Using Poisson regression models with robust standard errors, we assessed the effects of national identity and trust in government on the choice of COVID-19 vaccine brand. By analyzing data from 2361 participants, we found that national identity and trust in government were associated with the likelihood of COVID-19 vaccination, the number of vaccine doses received, and the brand of vaccine taken. Those who identified themselves as Taiwanese were more inclined to receive the Medigen and AstraZeneca vaccines, but less willing to receive Pfizer-BioNTech vaccine. Those who trusted the government were more likely to prefer and receive the Medigen vaccine. Conversely, those who didn't trust the government were less likely to prefer Medigen and AstraZeneca vaccines, but were willing to receive Pfizer-BioNTech vaccine. Vaccine brand preferences and uptake in Taiwan were affected by individuals' national identity and their trust in government. This highlights the critical role of sociopolitical factors in shaping public health strategies.

The emergence and successful elimination of SARS-CoV-2 dominant strains with increasing epidemic potential in Taiwan's 2021 outbreak

Taiwan's experience with severe acute respiratory syndrome coronavirus (SARS-CoV) in 2003 guided its development of strategies to defend against SARS-CoV-2 in 2020, which enabled the successful control of Coronavirus disease 2019 (COVID-19) cases from 2020 through March 2021. However, in late-April 2021, the imported Alpha variant began to cause COVID-19 outbreaks at an exceptional rate in Taiwan. In this study, we aimed to determine what epidemiological conditions enabled the SARS-CoV-2 Alpha variant strains to become dominant and decline later during a surge in the outbreak. In conjunction with contact-tracing investigations, we used our bioinformatics software, CoVConvert and IniCoV, to analyze whole-genome sequences of 101 Taiwan Alpha strains. Univariate and multivariable regression analyses revealed the epidemiological factors associated with viral dominance. Univariate analysis showed the dominant Alpha strains were preferentially selected in the surge's epicenter (p = 0.0024) through intensive human-to-human contact and maintained their dominance for 1.5 months until the Zero-COVID Policy was implemented. Multivariable regression found that the epidemic periods (p = 0.007) and epicenter (p = 0.001) were two significant factors associated with the dominant virus strains spread in the community. These dominant virus strains emerged at the outbreak's epicenter with frequent human-to-human contact and low vaccination coverage. The Level 3 Restrictions and Zero-COVID policy successfully controlled the outbreak in the community without city lockdowns. Our integrated method can identify the epidemiological conditions for emerging dominant virus with increasing epidemiological potential and support decision makers in rapidly containing outbreaks using public health measures that target fast-spreading virus strains.

Acute kidney disease following COVID-19 vaccination: a single-center retrospective study

Background

Rare cases of de novo or relapsed kidney diseases associated with vaccination against coronavirus disease 2019 (COVID-19) have been increasingly reported. The aim of this study was to report the incidence, etiologies, and outcomes of acute kidney disease (AKD) following COVID-19 vaccination.

Methods

This retrospective study extracted cases from renal registry of a single medical center from 1 March 2021 to 30 April 2022, prior to the significant surge in cases of the Omicron variant of COVID-19 infection in Taiwan. Adult patients who developed AKD after COVID-19 vaccination were included. We utilized the Naranjo score as a causality assessment tool for adverse vaccination reactions and charts review by peer nephrologists to exclude other causes. The etiologies, characteristics, and outcomes of AKD were examined.

Results

Twenty-seven patients (aged 23 to 80 years) with AKD were identified from 1,897 vaccines (estimated rate of 13.6 per 1000 patient-years within the renal registry). A majority (77.8%) of vaccine received messenger RNA-based regimens. Their median (IQR) Naranjo score was 8 (6-9) points, while 14 of them (51.9%) had a definite probability (Naranjo score ≥ 9). The etiologies of AKD included glomerular disease (n = 16) consisting of seven IgA nephropathy, four anti-neutrophil cytoplasmic antibodies-associated glomerulonephritis (AAN), three membranous glomerulonephritis, two minimal change diseases, and chronic kidney disease (CKD) with acute deterioration (n = 11). Extra-renal manifestations were found in four patients. Over a median (IQR) follow-up period of 42 (36.5-49.5) weeks, six patients progressed to end-stage kidney disease (ESKD).

Conclusion

Besides glomerulonephritis (GN), the occurrence of AKD following COVID-19 vaccination may be more concerning in high-risk CKD patients receiving multiple doses. Patients with the development of de novo AAN, concurrent extra-renal manifestations, or pre-existing moderate to severe CKD may exhibit poorer kidney prognosis.

Impact of COVID-19 Preventative Measures on Otolaryngology in Taiwan: A Nationwide Study

BACKGROUND

Taiwan always had low case rates of COVID-19 compared with other countries due to its immediate control and preventive measures. However, the effects of its policies that started on 2020 for otolaryngology patients were unknown; therefore, the aim of this study was to analyze the nationwide database to know the impact of COVID-19 preventative measures on the diseases and cases of otolaryngology in 2020.

METHOD

A case-compared, retrospective, cohort database study using the nationwide database was collected from 2018 to 2020. All of the information from outpatients and unexpected inpatients with diagnoses, odds ratios, and correlation matrix was analyzed.

RESULTS

The number of outpatients decreased in 2020 compared to in 2018 and 2019. Thyroid disease and lacrimal system disorder increased in 2020 compared to 2019. There was no difference in carcinoma in situ, malignant neoplasm, cranial nerve disease, trauma, fracture, and burn/corrosion/frostbite within three years. There was a highly positive correlation between upper and lower airway infections.

CONCLUSIONS

COVID-19 preventative measures can change the numbers of otolaryngology cases and the distributions of the disease. Efficient redistribution of medical resources should be developed to ensure a more equitable response for the future.

Trend in healthcare-associated infections due to vancomycin-resistant Enterococcus at a hospital in the era of COVID-19: More than hand hygiene is needed

BACKGROUND

Variable control measures for vancomycin-resistant Enterococcus (VRE) infections were adopted among different hospitals and areas. We investigated the burden and patient characteristics of healthcare-associated VRE infections in 2018-2019 and 2020, when multiple preventive measures for COVID-19 were taken.

METHODS

During the COVID-19 pandemic, mask waring and hand hygiene were enforced in the study hospital. The incidence densities of healthcare-associated infections (HAIs), including overall HAIs, methicillin-resistant Staphylococcus aureus (MRSA) HAIs, VRE HAIs, and VRE healthcare-associated bloodstream infections (HABSIs), consumption of broad-spectrum antibiotics and hygiene products, demographic characteristics and medical conditions of affected patients, were compared before and after the pandemic.

RESULTS

The incidence density of both VRE HAIs and VRE HABSIs did not change statistically significantly, however, the highest in 2020 than that in 2018 and 2019. This was in spite of universal mask waring and increased consumption of 75% alcohol in 2020 and consistent implementation of an antibiotic stewardship program in three observed years. The increased prescriptions of broad-spectrum cephalosporins might partially explain the increase of VRE infection.

CONCLUSION

Increased mask wearing and hand hygiene may not result in the decline in the development of VRE HAIs in the hospital during the COVID-19 pandemic, and continued monitoring of the dynamics of HAIs remains indispensable.

Indoxyl Sulfate Alters the Humoral Response of the ChAdOx1 COVID-19 Vaccine in Hemodialysis Patients

Background and aims: Vaccination for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) is strongly recommended. The efficacy of SARS-CoV-2 vaccine for patients with end-stage renal disease is low. Indoxyl sulfate (IS) is a representative protein bound uremic toxin arousing immune dysfunction in CKD patients. It is unknown whether IS impairs the efficacy of vaccines for SARS-CoV-2. Materials and Methods: From 1 June 2021, to 31 December 2021, hemodialysis patients (n = 358) and a control group (n = 59) were eligible to receive the first dose of the ChAdOx1 COVID-19 vaccine. Titer measurements indicative of the humoral response (anti-S1 IgG and surrogate virus neutralization test (sVNT) results) and indoxyl sulfate concentration measurement were performed 4 weeks after ChAdOx1 vaccine injection. Results: The serum concentrations of anti-S1 IgG were 272 ± 1726 AU/mL and 2111 ± 4424 AU/mL in hemodialysis patients and control group (p < 0.05), respectively. The sVNT values were 26.8 ± 21.1% and 54.0 ± 20.2% in the hemodialysis and control groups (p < 0.05), respectively. There was a decreasing trend for the anti-S1 IgG titer from the lowest to highest quartile of IS (p < 0.001). The patients with higher concentrations of IS had lower sVNT (p for trend < 0.001). Conclusion: Hemodialysis patients had weaker humoral immunity after the first dose of the ChAdOx1 vaccine. Higher concentration of IS altered the development of anti-S1 antibodies and sVNT-measured neutralization.

The implications of the COVID-19 pandemic for long term care facilities

PURPOSE OF REVIEW

Despite advances in infection prevention and control and breakthroughs in vaccination development, challenges remain for long-term care facilities (LTCFs) as they face a likely future of emerging infectious diseases. To ensure the safety of LTCF residents from the current and future pandemics, we identify lessons learned from the coronavirus disease 2019 (COVID-19) experience for improving future prevention and response efforts.

RECENT FINDINGS

In addition to high disease susceptibility among LTCF residents, LTCF vulnerabilities include a lack of pandemic preparedness, a lack of surge capacity in human, material and testing resources, and poorly designed buildings. External sources of vulnerability include staff working in multiple LTCFs and high COVID-19 rates in surrounding communities. Other challenges include poor cooperation between LTCFs and the other components of health systems, inadequately enforced regulations, and the sometimes contradictory interests for-profit LTCFs face between protecting their residents and turning a profit.

SUMMARY

These challenges can be addressed in the post-COVID-19 period through systemic reforms. Governments should establish comprehensive health networks that normalize mechanisms for prediction/preparedness and response/recovery from disruptive events including pandemics. In addition, governments should facilitate cooperation among public and private sector health systems and institutions while utilizing advanced digital communication technologies. These steps will greatly reduce the threat to LTCFs posed by emerging infectious diseases in future.

Effectiveness of controlling COVID-19 epidemic by implementing soft lockdown policy and extensive community screening in Taiwan

Strict and repeated lockdowns have caused public fatigue regarding policy compliance and had a large impact on several countries’ economies. We aimed to evaluate the effectiveness of a soft lockdown policy and the strategy of active community screening for controlling COVID-19 in Taiwan. We used village-based daily confirmed COVID-19 statistics in Taipei City and New Taipei City, between May 2, 2021, and July 17, 2021. The temporal Gi* statistic was used to compute the spatiotemporal hotspots. Simple linear regression was used to evaluate the trend of the epidemic, positivity rate from community screening, and mobility changes in COVID-19 cases and incidence before and after a level three alert in both cities. We used a Bayesian hierarchical zero-inflated Poisson model to estimate the daily infection risk. The cities accounted for 11,403 (81.17%) of 14,048 locally confirmed cases. The mean effective reproduction number (Re) surged before the level three alert and peaked on May 16, 2021, the day after the level three alert in Taipei City (Re = 3.66) and New Taipei City (Re = 3.37). Mobility reduction and a lower positive rate were positively associated with a lower number of cases and incidence. In the spatiotemporal view, seven major districts were identified with a radial spreading pattern from one hard-hit district. Villages with a higher inflow degree centrality among people aged ≥ 60 years, having confirmed cases, specific land-use types, and with a higher aging index had higher infection risks than other villages. Early soft lockdown policy and detection of infected patients showed an effective strategy to control COVID-19 in Taiwan.

Identification and Analysis of SARS-CoV-2 Alpha Variants in the Largest Taiwan COVID-19 Outbreak in 2021

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is believed to have originated in Wuhan City, Hubei Province, China, in December 2019. Infection with this highly dangerous human-infecting coronavirus via inhalation of respiratory droplets from SARS-CoV-2 carriers results in coronavirus disease 2019 (COVID-19), which features clinical symptoms such as fever, dry cough, shortness of breath, and life-threatening pneumonia. Several COVID-19 waves arose in Taiwan from January 2020 to March 2021, with the largest outbreak ever having a high case fatality rate (CFR) (5.95%) between May and June 2021. In this study, we identified five 20I (alpha, V1)/B.1.1.7/GR SARS-CoV-2 (KMUH-3 to 7) lineage viruses from COVID-19 patients in this largest COVID-19 outbreak. Sequence placement analysis using the existing SARS-CoV-2 phylogenetic tree revealed that KMUH-3 originated from Japan and that KMUH-4 to KMUH-7 possibly originated via local transmission. Spike mutations M1237I and D614G were identified in KMUH-4 to KMUH-7 as well as in 43 other alpha/B.1.1.7 sequences of 48 alpha/B.1.1.7 sequences deposited in GISAID derived from clinical samples collected in Taiwan between 20 April and July. However, M1237I mutation was not observed in the other 12 alpha/B.1.1.7 sequences collected between 26 December 2020, and 12 April 2021. We conclude that the largest COVID-19 outbreak in Taiwan between May and June 2021 was initially caused by the alpha/B.1.1.7 variant harboring spike D614G + M1237I mutations, which was introduced to Taiwan by China Airlines cargo crew members. To our knowledge, this is the first documented COVID-19 outbreak caused by alpha/B.1.1.7 variant harboring spike M1237I mutation thus far. The largest COVID-19 outbreak in Taiwan resulted in 13,795 cases and 820 deaths, with a high CFR, at 5.95%, accounting for 80.90% of all cases and 96.47% of all deaths during the first 2 years. The high CFR caused by SARS-CoV-2 alpha variants in Taiwan can be attributable to comorbidities and low herd immunity. We also suggest that timely SARS-CoV-2 isolation and/or sequencing are of importance in real-time epidemiological investigations and in epidemic prevention. The impact of G614G + M1237I mutations in the spike gene on the SARS-CoV-2 virus spreading as well as on high CFR remains to be elucidated.

Rapid response of a medical center upon the surge of COVID-19 epidemic in Taiwan

A surge of coronavirus disease (COVID-19) cases emerged in northern Taiwan in mid-May 2021. In spite of over one-year preparedness, the medical system in this area suffered from the crisis. Far Eastern Memorial Hospital (FEMH) responded quickly with decreased total hospitalization cases (about 50%) to free manpower and space. With simple construction work, the in-hospital service capacity increases from 11 negative-pressure ward (1 unit) and 2 negative-pressure ICU (1 unit) beds to over 130 ward (5 units) and 58 ICU beds (4 units) without negative-pressure design within 3 weeks. For a period of time, FEMH takes care of 10% of all intensive care services in Taiwan. The vaccination rate of workers reaches 90% since mid-May. The amount of testing performed during the period, including PCR and rapid tests, comprised of more than 20% of tests performed in New Taipei City. Two hotels for mild/asymptomatic COVID patients were handled by FEMH workers. By mid-July, about one-fifth of COVID-19 cases in New Taipei City received services from the FEMH system. With determined leadership and concerted efforts, combined interventions can increase the capacity of medical care within weeks and help society against the COVID-19 epidemic.
