RESUMEN
BACKGROUND: Although globalization promotes economic development, cross-border infectious disease transmission is still a serious threat to health. Taiwan is geographically close to Southeast and South Asia, but the needs and expectations of Taiwanese travelers with regard to travel medicine are still largely unknown. This study aimed to clarify the pretravel preparations, needs, willingness to seek pretravel consultation, and factors associated with willingness, in order to provide valuable information for improvement of healthcare service. METHODS: Data were collected with anonymous structured questionnaires distributed to 477 visitors who tried to get travel health information from New Southbound Health Center between June and November 2019. A multivariate stepwise logistic regression analysis was applied to identify factors associated with the visitors' willingness to seek pretravel consultation. RESULTS: A total of 304 questionnaires (64%) were collected. Eighty-three percent of the respondents were willing to seek pretravel consultation. A higher level of education (odds ratio 3.6 [95% CI 1.58-8.22]), having a plan to obtain travel medical insurance (2.5 [1.18-5.28]), concern with gastrointestinal diseases (2.0 [1.04-3.94]), concern with mosquito-borne diseases (2.0 [2.07-3.95]), and concern with noncommunicable diseases (2.2 [1.02-4.96]) were independent factors associated with willingness to seek pretravel consultation.: CONCLUSIONS: We found that most of the travelers were willing to seek pretravel consultation. Our study highlighted the need to enhance awareness about travel-related illness among these travelers. Strategies should be tailored according to these findings to help prevent epidemics and improve healthcare service in the future.

BACKGROUND: Coronavirus infectious disease 2019 (COVID-19) has had a great impact on global health, but with relatively few confirmed cases in Taiwan. People in Taiwan showed excellent cooperation with the government for disease prevention and faced social and behavioral changes during this period. This study aimed to investigate people's knowledge of COVID-19, attitudes and practices regarding vaccinations for influenza, pneumococcus and COVID-19. METHODS: We conducted a community-based, cross-sectional questionnaire survey from September 2020 to October 2020 among adults in northern Taiwan. The four-part questionnaire included questions on sociodemographic characteristics, knowledge, attitude, and practice toward COVID-19. RESULTS: Among a total of 410 respondents, 58.5% were categorized as having "good knowledge" responding to COVID-19. Among the total respondents, 86.6% were willing to receive influenza or pneumococcal vaccines, and 76% of them acted to receive COVID-19 immunization once the vaccine became available. Compared with the respondents with poor knowledge of COVID-19, those with good knowledge had a more positive attitude toward receiving influenza or pneumococcal immunization (OR 3.26, 95% CI = 1.74-6.12). CONCLUSIONS: Participants with good knowledge of COVID-19 had greater intent to receive immunization for influenza or pneumococcal vaccine. The promotion of correct knowledge of both COVID-19 and immunization preparations is necessary.

BACKGROUND: Inflammation plays an important role in the ageing process in which monocytes/macrophages are important players. Intercellular adhesion molecule-1 (ICAM-1), tumour necrosis factor-α (TNF-α) and Toll-like receptor 4 (TLR4) are well-known inflammatory markers. This study aimed to investigate the relationship between age and the expression and correlation of ICAM-1, TNF-α and TLR4 mRNA in peripheral blood mononuclear cells (PBMCs). METHODS: A total of 239 participants were recruited in a medical centre in Taiwan. The mRNA isolated from the PBMCs was used to determine the levels of ICAM-1, TNF-α and TLR4 mRNAs with real-time polymerase chain reaction (PCR). The propensity-matched analysis was also applied for subgroup analysis. RESULTS: When compared 189 older adults (â§65 years) to 50 younger adults (<65 years), the ICAM-1, TNF-α and TLR4 mRNA levels in PBMCs were significantly higher in older adults (2.00 ± 0.72 vs 0.87 ± 0.34 for ICAM-1, 2.32 ± 0.69 vs 1.15 ± 0.44 for TNF-α and 1.56 ± 0.47 vs 1.05 ± 0.51 for TLR4, and all P < .0001). Also, both age and TLR4 were independent factors affecting mononuclear cell ICAM-1 in the multiple linear regression analysis (P < .0001). CONCLUSION: The mRNA levels of ICAM-1 and TLR4 in PBMCs are higher in older adults than those in younger adults. TLR4 is an independent factor affecting ICAM-1 expression in PBMCs, especially in older adults. This may suggest that ICAM-1 and TLR4 in PBMCs are potential biomarkers and their relationship may shed some light on the ageing process.

BACKGROUND: Visceral adipose tissue dysfunction contributes to metabolic syndrome (MetS) and cardiovascular diseases. This study aims to investigate the association between visceral fat level measured by bioelectric impedance analysis (BIA) and MetS. MATERIAL AND METHODS: This cross-sectional study recruited Taiwanese volunteers aged ≥20 years between 2012 and 2014. Anthropometric measurements and plasma concentrations of glucose, insulin, and lipid profiles were collected after at least 8 h of fasting. Insulin resistance was calculated by the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). Visceral fat level (VFL, ranges: 1-59) and trunk fat percentage were measured through by the Body Composition Analyzer TANITA AB 140 Viscan. RESULTS: A total of 1086 volunteers (mean age = 44.2 ± 13.2 years) were enrolled. Multiple regression analyses showed that triglycerides levels and blood pressure increased while high-density lipoprotein-cholesterol decreased with VFL in both genders (p < 0.05). Increased HOMA-IR and VFL had a synergistic effect on MetS. Higher VFL was independently associated with MetS in both men (OR = 1.33, 95% CI: 1.19-1.48) and women (OR = 1.28, 95% CI: 1.17-1.39). CONCLUSIONS: Higher VFL is associated with MetS and its components. The portable BIA machine is easily applicable and useful tool to measure visceral fat in the community setting.
