Background/Aims: The global pandemic of COVID-19 has caused tremendous loss of human life since 2019. Vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is one of the best policies to control the pandemic. The vaccination efficacy in Taiwanese patients with different comorbidities is elusive and to be explored. Method(s): Uninfected subjects who received 3-doses of mRNA vaccines (Moderna, BioNTech), non-replicating viral vector-based vaccines (AstraZeneca, AZ) or protein subunit vaccines (Medigen COVID-19 vaccine, MVC) were prospectively enrolled. SARSCoV2- IgG spike antibody level was determined (Abbott [SARS-CoV- 2 IgG II]) within 3 months after the last dose of vaccination. Charlson Comorbidity Index (CCI) was applied to disclose the association of vaccine titer and underlying comorbidities. Result(s): A total of 824 subjects were enrolled in the current study. The mean age was 58.9 years and males accounted for 48.7% of the population. The proportion of CCI with 0-1, 2-3 and>4 was 52.8% (n = 435), 31.3% (n = 258) and 15.9% (n = 131), respectively. The most commonly used vaccination combination was AZ-AZ-Moderna (39.2%), followed by Moderna-Moderna-Moderna (27.8%) and AZAZ- BioNTech (14.7%), respectively. The mean vaccination titer was 3.11 log BAU/mL after a median 48 days of the 3rd dose. Subjects of male gender, lower body mass index, chronic kidney disease, higher CCI, and receiving AZ-AZ based vaccination were likely to have a lower titer of antibody. There was a decreasing trend of antibody titer with the increase of CCT (trend P<0.001). Linear regression analysis revealed that AZ-AZ-based vaccination (beta: 0.341, 95% confidence intervals [CI]: 0.144, 0.21, P<0.001) and higher CCI (beta: - 0.055, CI: - 0.096, - 0.014, P = 0.009) independently correlated with low IgG spike antibody levels. Conclusion(s): Patients with more comorbidities had a poor response to 3 doses of COVID-19 vaccination. Further studies are warranted to clarify the efficacy of booster vaccination in the population. The vaccine titer did not differ between patient with or without chronic liver disease.

Background and Objectives: The WHO has identified HCV infection as a public health threat and set a global target for HCV elimination by 2030, yet currently only 11 countries are on track to achieve HCV elimination targets. Up to 60% of HCV + patients are lost to follow-up and remain untreated and this has likely been further exacerbated by the COVID-19 pandemic, which may have reduced HCV treatment urgency, causing many patients to delay care. To achieve the WHO goal, still many patients need to be screened and linked to care. Gilead has been running Local Elimination Programs Leading to Global Action in HCV (LEGA-C) to support implementation science projects toward HCV elimination. Here, we explore the outcomes of LEGA-C programs for patients with HCV especially in Asia. Method(s): The outcomes and impact were measured through the number of studies and patients to be reached;steps in the care cascade as well as efficacy of each model were assessed along with the presentations and publications from each study. Result(s): In total,[120 studies were supported. Of these, 18 have completed or are ongoing in Asia. Through July 2022, 175,192 persons were screened, 6,287 were HCV + and enrolled in a study, and 3,768 received treatment. A simplified screening and linkage to care/ minimal monitoring model was investigated in 8 studies and demonstrated that linkage to care with minimal monitoring could achieve antiviral response comparable to standard practice.[i] Four test-and-treat studies showed that aggressive screening and on-site treatment promotes HCV microelimination.[ii] Three outreach-andcallback studies showed demonstrated the feasibility of recruiting persons to HCV screening programs in community settings.[iii] Seven studies focused on special populations, and 4 of them described the characteristics of special populations with higher rates of HCV infection. Publications from these studies in Asia include 14 full articles, and these papers were cited a total of 56 times. Conclusion(s): The ongoing LEGA-C initiative is demonstrably contributing to the understanding, treatment, and ultimate elimination of HCV. Innovative ideas, active promotion of HCV testing, disease education, patient navigation, and care coordination in these programs led to increased screening and rates of linkage to care. Adopting and adapting effective strategies from these programs may be a feasible way to increase treatment numbers and improve patient outcomes, thus contributing to meeting the WHO goal of HCV elimination in Asia.

Background: Hepatocellular carcinoma (HCC) is the second leading cause of malignancy-related mortality and the fifth most common worldwide. Immuno-cancer microenvironment (ICME) was highlighted recently because scientists want to unlock the detailed mechanism in carcinogenesis pathway and find the novel interactions in ICME. Besides, single cell analysis could mitigate the interrupted signals between cells and tissues. On the other hand, COVID-19 angiotensin I converting enzyme (ACE) previously was reported associated with cancer. However, the robust association between COVID-19 and HCC ICME is still unaddressed. Aim(s): We plan to investigate the COVID-19 ACE relevant genes to HCC ICME regarding survival. Method(s): We used Reactome for COVID-19 ACE gene pathway mapping and explored the positive relevant gene expression. DISCO website was applied for single cell analyses using the above-collected genes from Reactome. Finally, we implanted the biomedical informatics into TIMER 2.0 for ICME survival analyses. Result(s): In Fig. 1, the gene-gene interaction mapping was shown. We collected 13 genes (CPB2, ACE2, AGT, MME, ANPEP, CPA3, ENPEP, GZMH, CTSZ, CTSD, CES1, ATP6AP2, and AOPEP) for further single cell relevant analyses, in Table 1, with detailed expression level (TPM). Among the above 13 genes, AGT, GZMH, CTSZ, CTSD, CES1, and ATP6AP2 were strongly expressed in liver tissue. We then applied the initial 13 genes to TIMER 2.0 for HCC ICME 2-year survival analyses. CPA3 and GZMH low expressions with high macrophage infiltration in HCC ICME showed significantly worse 2-year cumulative survival [hazard ratio (HR):CPA3 2.21, p-value 0.018;GZMH 2.07, p-value 0.0341]. ACE2, CPB2, AGT, MME, ANPEP, ENPEP, CTSZ, CTSD, CES1, and ATP6AP2 high expressions with high macrophage infiltration in HCC ICME revealed significantly worse 2-year cumulative survival. Conclusion(s): We demonstrate that ACE2 was strongly associated with HCC clinical survival with macrophage infiltration. However, the bidirectional translational roles about ACE2 relevant genes in HCC should be documented.

Playfulness and quality of life (QoL) appear to be related constructs;however, no studies have explored the potential association between them to date. Playfulness and QoL are important practice-related concepts for education and therapy professionals who work with children and their families. This study examined the potential links between children's self-reported playfulness and QoL. Thirty-one typically developing children aged 8-12 years (average age 10 years and 9 months, standard deviation = 1.12;61.29% female) completed the Children's Perceptions of Their Play and the KIDSCREEN-52 instruments. It is noted that the onset of the COVID-19 pandemic during 2020 made participant recruitment and the execution of the study challenging. Data were analyzed using Spearman rho correlations and linear regression with bootstrapping. Data analysis results revealed statistically significant associations and predictive relationships between QoL-related physical wellbeing to active play and free time;QoL-related psychological wellbeing to the child's overall playfulness;the child's reported levels of QoL-related autonomy and their free time;and the child's QoL-related school environment to planned activities (p < .05 & p < .01). The study findings provide preliminary evidence that significant correlation and predictive relationships exist between aspects of children's self-reported playfulness and quality of life.
