Impact of COVID-19 Outbreak on Influenza and Pneumococcal Vaccination Uptake: A Multi-Center Retrospective Study.

During the coronavirus disease 2019 (COVID-19) pandemic, global vaccination efforts declined due to the burden on health systems and community resistance to epidemic control measures. Influenza and pneumococcal vaccines have been recommended for vulnerable populations to prevent severe pneumonia. We investigated community response towards influenza and pneumococcal vaccines (pneumococcal conjugate vaccine and pneumococcal polysaccharide vaccine) after the COVID-19 outbreak in Taiwan. We retrospectively included adults who visited Chang Gung Memorial Hospital (CGMH) institutions for influenza or pneumococcal vaccination from January 2018 to December 2021. The first case of COVID-19 in Taiwan was detected in January 2020; therefore, in this study, hospitalized cases from January 2018 to December 2019 were defined as "before COVID-19 outbreak," and hospitalized cases from January 2020 to December 2021 were defined as "after COVID-19 outbreak". A total of 105,386 adults were enrolled in the study. An increase in influenza vaccination (n = 33,139 vs. n = 62,634) and pneumococcal vaccination (n = 3035 vs. n = 4260) were observed after the COVID-19 outbreak. In addition, there was an increased willingness to receive both influenza and pneumococcal vaccinations among women, adults without underlying disease and younger adults. The COVID-19 pandemic may have increased awareness of the importance of vaccination in Taiwan.

Medical outcomes of children with neurodevelopmental disorders after SARS-CoV-2 vaccination: A six-month follow-up study.

INTRODUCTION: The BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) vaccines have been approved for children and adolescents for protecting against SARS-CoV-2 infection. This longitudinal study aimed to compare adverse outcomes after SARS-CoV-2 vaccination in children with neurodevelopmental disorders (ND) (e.g., attention-deficit/hyperactivity disorder [ADHD], autism spectrum disorder [ASD], communication disorders, intellectual disability, and tic disorders) and healthy control children. METHODS: A total of 1335 children who received the SARS-CoV-2 vaccination (762 children with ND and 573 healthy controls) were recruited. All subjects were followed-up for 180 days, and outcome events were defined as outpatient department (OPD) or emergency department (ER) visits during follow-up. Multivariate Cox proportional hazards regression models were used to identify the potential differences in outcomes between the propensity score-matched ND group (n = 311) and the control group (n = 311), and to explore the factors associated with outcomes among all children with ND (n = 762). RESULTS: Compared with the control group, children with ND exhibited a higher likelihood of subsequent OPD or ER visits and paediatric neurology OPD visits after the first dose of vaccination. However, we found that only a small proportion of the children visited the OPD or ER because of adverse vaccination-related effects. Among all children with ND, those with communication disorders showed a higher likelihood of any OPD or ER visit. Paediatric neurology OPD visits were associated with communication disorders, intellectual disability, and methylphenidate and aripiprazole prescriptions. ADHD and ASD were not associated with adverse outcomes. CONCLUSIONS: No specific ND diagnosis or medication use clearly increased the risk of adverse effects of SARS-CoV-2 vaccination. Children with ND can be reassured that the SARS-CoV-2 vaccination is a safe regimen to protect themselves.

Clinical effectiveness of molnupiravir in patients with COVID-19 undergoing haemodialysis.

BACKGROUND: Molnupiravir is an essential oral antiviral agent against coronavirus disease 2019 (COVID-19); however, its real-world effectiveness has not been evaluated in patients undergoing haemodialysis (HD). METHODS: This multi-centre retrospective study, involving 225 patients undergoing HD with initially mild or asymptomatic COVID-19, was conducted to compare the risks of 30-day COVID-19-related acute care visits between patients receiving and not receiving molnupiravir. Patients who received molnupiravir were stratified by rapid antigen detection (RAD) test results on day 7 after disease onset to assess whether rapid molnupiravir introduction accelerated viral clearance. RESULTS: Thirty-day COVID-19-related acute care visits were reported in 9.41% and 21.74% of the molnupiravir and control groups, respectively, and use of molnupiravir markedly reduced the risk of acute care visits after adjusting for baseline characteristics via propensity score weighting [hazard ratio 0.218, 95% confidence interval (CI) 0.074-0.642; P=0.006]. The tolerability of molnupiravir in the enrolled patients was generally acceptable, with only 11.88% of molnupiravir users reporting mild adverse events. Moreover, rapid initiation of molnupiravir within 1 day of COVID-19 onset was an independent predictor of conversion to a negative RAD test result on day 7 after disease onset (odds ratio 6.207, 95% CI 2.509-15.358; P<0.001). CONCLUSIONS: Molnupiravir is well tolerated and decreases the medical needs in patients with COVID-19 undergoing HD. Furthermore, the rapid initiation of molnupiravir accelerates viral clearance in patients with COVID-19 undergoing HD. These findings highlight the therapeutic role of molnupiravir for this vulnerable population.

Parental Attitudes, Intentions, Decisions, and Psychological Wellbeing Regarding COVID-19 Vaccination: Preschool, School-Age, and Adolescent Caregivers.

The vaccination of all children may be one of the most important public health measures for preventing a wider spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the community. Therefore, the purpose of this study was to investigate the attitude, intention, decision making, and psychological well-being among the caregivers of children who received SARS-CoV-2 vaccination in Taiwan. The caregivers of children (98 preschool children, 191 school-age children, and 154 adolescents) who received COVID-19 vaccination were invited to fill in the following questionnaires: Adopting Self-Protective Behavior Scale, Drivers of COVID-19 Vaccination Acceptance Scale, Impact of Event Scale, Chinese Health Questionnaire, and Parental Bonding Instrument. Compared to the caregivers of adolescents, the caregivers of preschool children exhibited more protective behaviors toward the COVID-19 pandemic. The caregivers of preschool children also displayed a higher emotional impact than those of adolescents and took a greater interest in the family's opinion about vaccination. Finally, we found that COVID-19 ideological invasion and protective parenting style were significantly related to the prevalence of mental illness among caregivers. The results of this study can be used as an important reference for vaccination health care and policy formulation for adolescents with regard to COVID-19.

Impact of Acid Suppression Therapy on Renal and Survival Outcomes in Patients with Chronic Kidney Disease: A Taiwanese Nationwide Cohort Study.

Histamine-2-receptor antagonist (H2RA) has shown beneficial effects on the kidney, heart, and sepsis in animal models and on the heart and COVID-19 infection in clinical studies. However, H2RAshave been used as a reference in most epidemiological studies examining the association of proton pump inhibitors (PPI) with outcomes. Therefore, we aimed to evaluate the effect of H2RA on renal and survival outcomes in chronic kidney disease (CKD) patients. We used a Taiwanese nationalhealth insurance database from 2001 to 2016 to screen 45,767 CKD patients for eligibility. We identified new users of PPI (n = 7121), H2RA (n = 48,609), and users of neither PPI nor H2RA (as controls) (n = 47,072) during follow-up, and finally created 1:1:1 propensityscore-matchedcohorts; each cohort contained 4361 patients. Participants were followed up after receivingacid-suppression agents or on the corresponding date until the occurrence of end-stage renal disease (ESRD) in the presence of competing mortality, death, or through the end of 2016. Compared toneither users, H2RAand PPI users demonstrated adjusted hazard ratios of 0.40 (95% confidence interval, 0.30-0.53) for ESRDand 0.64 (0.57-0.72) for death and 1.15 (0.91-1.45) for ESRD and 1.83 (1.65-2.03) for death, respectively. A dose-response relationship betweenH2RA use with ESRD and overall, cardiovascular, and non-cardiovascular mortality was detected. H2RA consistently provided renal and survival benefits on multivariable stratified analyses and multiple sensitivity analyses. In conclusion, dose-dependent H2RA use was associated with a reduced risk of ESRD and overall mortality in CKD patients, whereas PPI use was associated with an increased risk of overall mortality, not in a dose-dependent manner.

The Granting of Emergency Use Designation to COVID-19 Candidate Vaccines : Implications for COVID-19 Vaccine Trials

An efficacious COVID-19 vaccine is currently the world's leading research priority. Several nations have indicated that if there is a compelling case for use of a vaccine before it is licensed, they would be prepared to authorise its emergency use or conditional approval on public health grounds. As of Dec 1, 2020, several developers of leading COVID-19 candidate vaccines have indicated that they have applied, or intend to apply, for emergency authorisation for their vaccines. Should candidate vaccines attain emergency use designation and be programmatically deployed before their phase 3 trials conclude, such a strategy could have far reaching consequences for COVID-19 vaccine research and the effective control of the COVID-19 pandemic. These issues merit careful consideration.

Air Sampling for Fungus around Hospitalized Patients with Coronavirus Disease 2019.

The risk of developing coronavirus disease 2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) depends on factors related to the host, virus, and treatment. However, many hospitals have modified their existing rooms and adjusted airflow to protect healthcare workers from aerosolization, which may increase the risk of Aspergillus exposure. This study aimed to quantitatively investigate airborne fungal levels in negative and slightly negative pressure rooms for COVID-19 patients. The air in neutral pressure rooms in ordinary wards and a liver intensive care unit with high-efficiency particulate air filter was also assessed for comparison. We found the highest airborne fungal burden in recently renovated slightly negative air pressure rooms, and a higher airborne fungal concentration in both areas used to treat COVID-19 patients. The result provided evidence of the potential environmental risk of CAPA by quantitative microbiologic air sampling, which was scarcely addressed in the literature. Enhancing environmental infection control measures to minimize exposure to fungal spores should be considered. However, the clinical implications of a periodic basis to determine indoor airborne fungal levels and further air sterilization in these areas remain to be defined.

Deploying Robotic System In the PCR Testing: The Regulatory Basis for the Medicine In the Era of Automation

Since the outbreak of COVID-19, the public health agencies have been seriously challenged by the pandemic;countries tried to accelerate the quality and quantity of PCR test and tried to improve the storage of testing reagent with different solutions. In Taiwan, TFDA authorized case-by-case on the importation of test reagent for the emergency use and assisted the domestically produced test reagent. In Japan, the robot manufacturer developed an automated PCR viral testing robot system in crowded places, such as airports and stadiums to speed up the test and ceased the infection risk when the health professionals collected the sample. There was also an automated system for the analysis of the novel coronavirus, which the pre-process could automatically conduct the gene analysis to the positive sample, monitor the infection status of the sample and detect new variants. In the Netherlands, the research institute developed a pioneering automated test robot, which claimed to be the fastest and most accurate robotic test system.

Impact on Mental Well-Being and Resilience of Patients with Multiple Chronic Conditions in Different Periods during the Coronavirus Disease 2019 Outbreak in Taiwan.

Concerns over the coronavirus disease 2019 (COVID-19) pandemic and control measures have affected the routine outpatient visits of individuals with comorbidities and their mental well-being. From October 2019 to August 2020, this cross-sectional study enrolled 135 patients who sought medical attention at a medical center in Taiwan. This period covered the early (October to December 2019), peak (January to April 2020), and late (May to August 2020) periods of the COVID-19 outbreak in Taiwan. The demographic data, social support data, activities of daily living (ADL), resilience scale scores, and mental well-being scale scores of the participants were compared. There were no statistically significant differences in the participation rate, demographic data, and social support data between the three periods. The correlation analysis confirmed significant negative relationships between the number of COVID-19 cases and outpatient department visits per month (r = -0.764, p < 0.001), emergency department visits per month (r = -0.023, p < 0.001), ADL (r = -0.257, p = 0.03), resilience scale (r = -0.390, p < 0.001), and mental well-being scale (r = -0.475, p < 0.001). In conclusion, the severity of the COVID-19 outbreak in Taiwan was associated with declines in the ADL, mental well-being, and resilience of patients who sought medical attention.
