Self-perceived knowledge, attitude, and practice of evidence-based medicine before and after training among healthcare workers in Taizhou, China.

BACKGROUND: Evidence-based medicine (EBM) is the combination of the best research evidence with our clinical expertise, specific situations, and the unique values of our patients. It is essential to evaluate the effectiveness of EBM training for healthcare workers (HCWs). OBJECTIVES: This study aims to assess the impact of EBM training on HCWs' knowledge, attitude, and practice (KAP) related to EBM. METHODS: A self-reported online survey was carried out to investigate KAP related to EBM among HCWs at a tertiary hospital in Taizhou, China. HCWs participated in EBM training on 9 and 10 September 2023. The questionnaire survey was conducted to understand KAP related to EBM before and after the training, and to compare and analyze the results before and after the training. The R software (version 4.1.0) was used to analyze data. RESULTS: Sixty-four HCWs completed the survey with a response rate of 52.5% (64/122). The overall average scores of KAP related to EBM before training were 55.3, 63.0, and 34.5, respectively, and 56.9, 66.5, and 34.7 were the scores of KAP after training. HCWs' scores of knowledge (P = 0.033) and attitude (P < 0.001) related to EBM improved significantly after the training. CONCLUSION: This study implied that EBM training may improve the knowledge and attitude of HCWs, and its teaching effect is considerable.

Association between abusive supervision and nurses' withholding voice about patient safety: the roles of impression management motivation and speak up-related climate.

BACKGROUND: Abusive supervision by the nurse manager significantly influences nurses' withholding voice about patient safety. The role of impression management motivation and speak up-related climate is crucial in understanding their connection. This study aimed to explore the relationship between abusive supervision, impression management motivation, speak up-related climate, and withholding voice about patient safety. METHODS: This cross-sectional study employed a convenience sampling method to recruit 419 clinical nurses from Taizhou Hospital, Zhejiang Province, China, between 1 November 2022 and 31 January 2023. The study adhered to the STROBE checklist. Abusive supervision and impression management motivation were assessed using the Chinese versions of the Abusive Supervision Scale and the Impression Management Motivation Scale, respectively. Withholding voice about patient safety and speak up-related climate were identified using the Chinese version of the Speaking Up about Patient Safety Questionnaire. RESULTS: Nurse leaders' abusive supervision (ß=0.40, p<0.01) and nurses' impression management motivation (ß=0.10, p<0.01) significantly and positively influenced nurses' withholding voice about patient safety. We introduced impression management motivation as a mediating variable, and the effect of abusive supervision on nurses' withholding voice decreased (ß from 0.40 to 0.38, p< 0.01). Nurses' speak up-related climate played a moderating role between abusive supervision and impression management motivation (ß= 0.24, p<0.05). CONCLUSIONS: Abusive supervision by nursing leaders can result in nurses withholding voice about patient safety out of self-protective impression management motives. This phenomenon inhibits nurses' subjective initiative and undermines their proactive involvement in improving patient safety, and hinders the cultivation of a culture encouraging full participation in patient safety, which should warrant significant attention.

Complete response to first-line osimertinib monotherapy in a complex epidermal growth factor receptor mutant ( L833V / H835L ) lung adenocarcinoma patient: a case report.

Although uncommon epidermal growth factor receptor (EGFR) mutations account for 10-15% EGFR mutant non-small cell lung cancer (NSCLC) patients, clinical evidence for uncommon EGFR mutations, such as complex mutations remain limited. In this study, we reported a NSCLC patient harboring complex EGFR L833V / H835L mutation in exon 21, who had a complete response to first-line osimertinib monotherapy. The patient admitted to our hospital for space-occupying lesions of right lower lung during an annual health checkup, and was diagnosed as stage IIIA lung adenocarcinoma. Targeted next-generation sequencing (NGS) on tumor samples showed a complex EGFR mutation: L833V / H835L in exon 21. Therefore, she was treated with osimertinib monotherapy and complete remission achieved soon. During follow-up period, no metastasis was found and serum carcinoembryonic antigen returned to normal. In addition, NGS monitoring of mutations in circulating tumor DNA maintained negative. The patient remain benefitted for osimertinib monotherapy over 22 months with no disease progression. Our case firstly provided clinical evidences of first-line osimertinib therapy in lung cancer patients with rare L833V / H835L EGFR mutation.

Particulate matter of air pollution may increase risk of kidney failure in IgA nephropathy.

IgA nephropathy (IgAN) is characterized by deposition of galactose-deficient IgA1 (Gd-IgA1) in glomerular mesangium associated with mucosal immune disorders. Since environmental pollution has been associated with the progression of chronic kidney disease in the general population, we specifically investigated the influence of exposure to fine particulate matter less than 2.5 µm in diameter (PM2.5) on IgAN progression. Patients with biopsy-proven primary IgAN were recruited from seven Chinese kidney centers. PM2.5 exposure from 1998 to 2016 was derived from satellite aerosol optical depth data and a total of 1,979 patients with IgAN, including 994 males were enrolled. The PM2.5 exposure levels for patients from different provinces varied but, in general, the PM2.5 exposure levels among patients from the north were higher than those among patients from the south. The severity of PM2.5 exposure in different regions was correlated with regional kidney failure burden. In addition, each 10 µg/m3 increase in annual average concentration of PM2.5 exposure before study entry (Hazard Ratio, 1.14; 95% confidence interval, 1.06-1.22) or time-varying PM2.5 exposure after study entry (1.10; 1.01-1.18) were associated with increased kidney failure risk after adjustment for age, gender, estimated glomerular filtration rate, urine protein, uric acid, hemoglobin, mean arterial pressure, Oxford classification, glucocorticoid and renin-angiotensin system blocker therapy. The associations were robust when the time period, risk factors of cardiovascular diseases or city size were further adjusted on the basis of the above model. Thus, our results suggest that PM2.5 is an independent risk factor for kidney failure in patients with IgAN, but these findings will require validation in more diverse populations and other geographic regions.

High-dimensional mediation analysis in survival models.

Mediation analysis with high-dimensional DNA methylation markers is important in identifying epigenetic pathways between environmental exposures and health outcomes. There have been some methodology developments of mediation analysis with high-dimensional mediators. However, high-dimensional mediation analysis methods for time-to-event outcome data are still yet to be developed. To address these challenges, we propose a new high-dimensional mediation analysis procedure for survival models by incorporating sure independent screening and minimax concave penalty techniques for variable selection, with the Sobel and the joint method for significance test of indirect effect. The simulation studies show good performance in identifying correct biomarkers, false discovery rate control, and minimum estimation bias of the proposed procedure. We also apply this approach to study the causal pathway from smoking to overall survival among lung cancer patients potentially mediated by 365,307 DNA methylations in the TCGA lung cancer cohort. Mediation analysis using a Cox proportional hazards model estimates that patients who have serious smoking history increase the risk of lung cancer through methylation markers including cg21926276, cg27042065, and cg26387355 with significant hazard ratios of 1.2497(95%CI: 1.1121, 1.4045), 1.0920(95%CI: 1.0170, 1.1726), and 1.1489(95%CI: 1.0518, 1.2550), respectively. The three methylation sites locate in the three genes which have been showed to be associated with lung cancer event or overall survival. However, the three CpG sites (cg21926276, cg27042065 and cg26387355) have not been reported, which are newly identified as the potential novel epigenetic markers linking smoking and survival of lung cancer patients. Collectively, the proposed high-dimensional mediation analysis procedure has good performance in mediator selection and indirect effect estimation.

The importance of air quality for underground spaces: An international survey of public attitudes.

Space is a resource that is constantly being depleted, especially in mega-cities. Underground workspaces (UGS) are increasingly being included in urban plans and have emerged as an essential component of vertical cities. While progress had been made on the engineering aspects associated with the development of high-quality UGS, public attitudes toward UGS as work environments (ie, the public's design concerns with UGS) are relatively unknown. Here, we present the first large-scale study examining preferences and attitudes toward UGS, surveying close to 2000 participants from four cities in three continents (Singapore, Shanghai, London, and Montreal). Contrary to previous beliefs, air quality (and not lack of windows) is the major concern of prospective occupants. Windows, temperature, and lighting emerged as additional important building performance aspects for UGS. Early adopters (ie, individuals more willing to accept UGS and thus more likely to be the first occupants) across all cities prioritized air quality. Present results suggest that (perceived) air quality is a key building performance aspect for UGS that needs to be communicated to prospective occupants as this will improve their attitudes and views toward UGS. This study highlights the importance of indoor air quality for the public.

Sex differences in the relationship between post-vaccination adverse reactions, decision regret, and WTP for the booster dose of COVID-19 vaccine in Taizhou, China.

This study investigated sex differences in the relationship between post-vaccination adverse reactions, decision regret, and willingness to pay (WTP) for the booster dose of COVID-19 vaccines. This research carried out an online cross-sectional investigation among healthcare workers (HCWs) in Taizhou, China. In total, 1,054 respondents (165 males and 889 females) have received two-dose COVID-19 vaccination. We performed descriptive analysis, chi-square test, and mediation analysis on the exported data. In this study, 67 (40.6%) males and 429 (48.3%) females had WTP for the booster dose. Our study presented that decision regret mediated the effect of adverse reactions after vaccination on WTP for the booster dose in both male and female groups. In males, decision regret played a completely mediating role, while in females, it acted as a partial mediator. Sex differences in the relationship between post-vaccination side effects, decision regret, and WTP for the third dose were demonstrated in a sample of healthcare workers.

Application of a Comprehensive Model Based on CT Radiomics and Clinical Features for Postoperative Recurrence Risk Prediction in Non-small Cell Lung Cancer.

RATIONALE AND OBJECTIVES: We constructed a comprehensive model by combining the radiomics and clinical features of tumors to predict the recurrence risk of patients with operable stage IA-IIIA non-small cell lung cancer (NSCLC). Our aim was to improve the accuracy of prognostic prediction and provide personalized treatment plans to enhance patient outcomes. MATERIALS AND METHODS: We retrospectively analyzed 152 surgically treated patients with pathologically confirmed stage IA-IIIA NSCLC. These patients were randomly divided into a training cohort and a test cohort in an 8:2 ratio. Using the 3D Slicer image computing platform, we manually delineated the regions of interest (ROI) for all lesions and extracted radiomics features using Python. We used the Least Absolute Shrinkage and Selection Operator (LASSO) to select the radiomics features, while the COX multivariate regression model was employed to identify independent clinical risk factors for recurrence. Finally, we utilized logistic regression (LR) to build the model and validated it using the receiver operating characteristic curve (ROC). The predictive performance of the model was evaluated using the concordance index (C-index), and the clinical value of the model was compared through decision curve analysis (DCA). RESULTS: We extracted a total of 1562 radiomics features. After feature selection, we retained 29 features. The COX multivariate regression model demonstrated that the N stage was an independent risk factor for postoperative recurrence. In the training and test cohorts, the area under the curve (AUC) values of the radiomics-clinical comprehensive model were 0.972 and 0.937, respectively, while the C-index values were 0.815 and 0.847. These values surpassed those of the standalone clinical model or radiomics model. CONCLUSION: Our study demonstrates that a comprehensive model based on CT radiomics and clinical features can effectively stratify the risk of postoperative recurrence in patients with operable NSCLC. It provides a powerful tool for accurately stratifying the risk of high-risk patients after surgery.

Hiding scrambled text messages in speech signals using a lightweight hyperchaotic map and conditional LSB mechanism.

This study presents a lightweight, secure audio steganography system for hiding text messages for transmission over the Internet, with the aim of addressing the current problems of high computational cost and insufficient security identified in earlier studies. We propose a two-phase functioning mechanism. Text characters are first transformed into ASCII code and stored in a vector, which is then divided into three sub-vectors. These sub-vectors are scrambled using two low-complexity operations, namely a forward-backward reading technique and an odd-even index. Two scrambling loops are performed, the first on the small sub-vectors the second on the vector as a whole. In the hiding phase, the speech signal samples are divided into 256 blocks using only 200 values per block, and low-complexity quadratic and the Hénon maps are used to hide the speech signal in a random manner. The conditional LSB is applied as a low-complexity algorithm to identify hidden bits, and a special hyperchaotic map algorithm is developed to randomly choose locations. The proposed approach provides good security for a scrambled text message, with high SNR and PSNR, small MSE and PESQ, a SSIM value of close to one (As indicated in Tables 1, 2, 3, and 4), a BER value of close to zero (as shown in table 8), NCC value near +1 (as shown in table 8), and an MOS value of near five (as described in table 6), as well as a low computational hiding cost.

Stroke related knowledge, prevention practices and associated factors among stroke patients in Taizhou, China.

Stroke is characterized by high morbidity, high mortality and high disability rate, which is a major health problem worldwide. However, most community-based studies report a lack of public knowledge related to stroke. The aim of this study is to investigate stroke-related knowledge and prevention practices among stroke patients in Taizhou, China. A face-to-face survey was conducted and questionnaires were completed by 156 S patients from June 27 to August 30, 2022. A generalized linear model was applied to explore the factors influencing prevention practices. Among the total participants, 36.5% and 40.4% of them had good knowledge of the stroke-related warning signs and risk factors, respectively. Participants who had good stroke prevention practices accounted for 57.7%. The higher score of stroke-related knowledge among inpatients, the better their prevention practices (B = 0.16, 95 %CI: 0.05 âˆ¼ 0.28). In addition, those with age ≥ 60 (B = 1.20, 95 %CI: 0.42 âˆ¼ 1.97), females (B = 0.93, 95 %CI: 0.24 âˆ¼ 1.61), having physical activities (B = 1.01, 95 %CI: 0.33 âˆ¼ 1.68), or without underlying diseases (B = -1.67, 95 %CI:-2.42 âˆ¼ -0.92) were also related with prevention practices. In general, this survey indicated that the stroke-related knowledge and prevention practices of participants were not good enough. Stroke related knowledge, age, sex, physical activity, and underlying disease were significant factors related to stroke prevention practices. These findings suggest the need to focus on stroke health education for stroke patients.

Correlation Between Ontological Insecurity and Daily Epidemic Prevention Behavior Among Inpatients During the COVID-19 Pandemic.

This study evaluates inpatients' ontological insecurity and daily epidemic prevention behavior during the pandemic and explores the factors influencing daily epidemic prevention behaviors. The outbreak of coronavirus disease (COVID-19) in December 2019 caused a global public health crisis that has affected the very structure of society and the order of daily life. Ontological security is the ability to predict the impact of changes in social environments on personal security, such as during the pandemic. A cross-sectional study was used to collect data from 1185 inpatients of a hospital in Zhejiang, China, from July 11 to August 9, 2021. Our questionnaire recorded information on demographics, ontological insecurity, and daily epidemic prevention behaviors. The Mann-Whitney U test, Kruskal-Wallis H test, Spearman's correlation analysis, and logistic regression analysis were used to determine the influencing factors of daily epidemic prevention behavior on ontological security. Results showed a negative correlation between inpatients' ontological insecurity and daily epidemic prevention behavior (r = -.253, P < .001). The logistic regression analysis showed that the independent factors affecting daily epidemic prevention behavior include ontological insecurity (OR: 0.952; 95% CI: 0.937-0.968) (P < .001), sex (OR: 1.292; 95% CI: 1.004-1.663), age (OR: 0.880; 95%: 0.790-0.980), education (OR: 1.307; 95% CI: 1.098-1.556), and occupation [famers vs civil servants, staff or professional (OR: 0.596; 95% CI: 0.374-0.949),other versus civil servants, staff, or professional (OR: 0.693; 95% CI: 0.503-0.953)] (P < .05). Inpatients were shown to have good ontological security during the COVID-19 epidemic, younger patients, female patients, patients with stronger ontological security, patients with a higher educational level, and those who work in a fixed unit or organization showed higher levels of daily epidemic prevention behavior. Hospital managers should strengthen the intervention management of epidemic prevention behavior based on patient characteristics.

The Clinical Significance and Prognostic Value of ALDH1 Expression in Non-small Cell Lung Cancer: A Systematic Review and Meta-analysis.

BACKGROUND: The results of the association between aldehyde dehydrogenase 1 (ALDH1) expression and prognosis of non-small cell lung cancer (NSCLC) are contradictory. We conducted this meta-analysis to investigate the clinical significance and prognostic value of ALDH1 in NSCLC. METHODS: The databases PubMed, Web of Science, EMBASE, the Cochrane Library, Wanfang, and CNKI were systematically queried to identify eligible studies. The retrieval time was from database establishment to August 2023. We evaluated the correlation between ALDH1 expression and clinical features of NSCLC by employing odds ratios (ORs) and 95% confidence intervals (95% CIs). In addition, we used hazard ratios (HRs) and 95% CIs to evaluate the role of ALDH1 expression in the prognosis of NSCLC. RESULTS: Our study included 21 literatures involving 2721 patients. The expression of ALDH1 in NSCLC was higher than that in normal tissues (OR = 6.04, 95% CI: 1.25-29.27, P = 0.026). The expression of ALDH1 was related to TNM stage (OR = 1.81, 95% CI: 1.06-3.09, P = 0.029), tumor grade (OR = 0.29, 95% CI: 0.17-0.48, P < 0.0001), lymph node metastasis (OR = 2.60, 95% CI: 1.52-4.45, P = 0001) and histological subtype (OR = 0.67, 95% CI: 0.52-0.86, P = 0.002). In patients with NSCLC, we found that the over-expression of ALDH1 was significantly associated with poor overall survival (OS) (HR = 1.44, 95% CI: 1.15-1.81, P = 0.002) and disease-free survival (DFS) (HR = 1.74, 95% CI: 1.45-2.10, P < 0.0001). CONCLUSION: The expression of ALDH1 is closely associated with the clinicopathologic characteristics and prognosis of NSCLC. ALDH1 may serve as a valuable clinical assessment tool and prognostic predictor in NSCLC.

Molecular characteristics of multiple primary pulmonary nodules under a three-dimensional reconstruction model and relevant multi-omics analyses: a case report.

Background: In addition to CT images and pathological features, many other molecular characteristics remain unknown about multiple primary lung cancer (MPLC) from intrapulmonary metastatic lung cancer. Case presentation: In this study, we reported a patient with an early-stage MPLC with both adenocarcinoma in situ (AIS) subtype and minimally invasive adenocarcinoma (MIA) subtype. The patient was diagnosed with more than 10 nodules and underwent precise surgery assisted by three-dimensional (3D) reconstruction at the left upper lung lobe. Whole-exome sequencing (WES) and multiple immunohistochemistry (mIHC) were performed to reveal the genomic profiling and tumor microenvironments of multiple nodules in this patient with MPLC. Based on 3D reconstruction location information, we found that the genomic and pathological results of adjacent lymph nodes were quite different. On the other hand, PD-L1 expression and the proportion of infiltrating lymphocytes in tumor microenvironments were all at a low status and did not vary in adjacent lymph nodes. Additionally, maximum diameter and tumor mutational burden levels were found to be significantly associated with CD8+ T cell proportion (p<0.05). Besides, CD163+ macrophages and CD4+ T cell proportion were higher in MIA nodules than in AIS nodules (p<0.05). This patient reached a recurrence-free survival of 39 months. Conclusion: Generally, in addition to CT imaging and pathological results, genomic profiling and tumor microenvironments may facilitate identifying the potential molecular mechanisms and clinical outcomes in patients with early-stage MPLC.

COVID-19 Vaccination in China: Adverse Effects and Its Impact on Health Care Working Decisions on Booster Dose.

Although many research studies have concentrated on people's willingness to take the COVID-19 vaccine, little attention has been paid to the underlying mechanism of consent. An understanding of potential factors and mechanisms that affect the willingness to receive a vaccination can contribute information critical for containing the pandemic. This study explored the effects of post-vaccination adverse reactions on the willingness to take the booster dose and the role of decision regret. A self-administered online survey was carried out in Taizhou, China. Questionnaires were completed by 1085 healthcare workers (HCWs), 1054 (97.1%) of whom had completed two doses of the COVID-19 vaccine. Mediation analysis methodology was applied in this study. Our study showed that post-vaccination adverse reactions in HCWs could decrease their willingness to take the booster dose. Of note, HCWs who experienced adverse reactions after vaccination would be more likely to regret their previous vaccination decisions, which, in turn, further reduced their willingness to receive a booster shot. Decision regret mediated the relationship between adverse post-vaccination reactions and a willingness to take the booster dose. The findings implied inextricable relationships among post-vaccination adverse reactions, decision regret, and willingness to take the booster dose. It is suggested that notice of these post-vaccination adverse reactions should be further incorporated into vaccine communication campaigns and policy interventions advocating booster doses to improve vaccine uptake intent and increase the willingness to receive booster doses of a COVID-19 vaccine.

Post-vaccination adverse reactions, decision regret, and willingness to pay for the booster dose of COVID-19 vaccine among healthcare workers: A mediation analysis.

This study aimed to explore the relationship between post-vaccination adverse reactions, decision regret, and willingness to pay (WTP) for the booster dose. An online survey was conducted in Taizhou, China. Questionnaires were completed by 1,085 healthcare workers (HCWs) and 1,054 (97.1%) have received two doses of the COVID-19 vaccine. Mediation analysis method was adopted. Our study presented that post-vaccination adverse reactions in HCWs could decrease their WTP for the booster dose. Of note, HCWs experienced adverse reactions after vaccination would more likely regret their previous vaccination decisions, which, in turn, further reduced their WTP for a booster shot. Decision regret mediated the relationship between adverse post-vaccination reactions and WTP for the booster dose. The findings implied inextricable relationships among post-vaccination adverse reactions, decision regret, and WTP of the booster dose. It suggested that these post-vaccination adverse reactions should be further incorporated into vaccine campaigns to improve vaccine intention and potentially increase willingness to pay for booster doses of COVID-19 vaccine.

Patients' Responses to COVID-19 Pandemic: The Relationship Between Potential Pandemic-Induced Disruptions, Ontological Security, and Adaptive Responses in Taizhou, China.

Background: The COVID-19 pandemic has changed the social environment of most individuals around the world and has profoundly impacted people's lives, ontological security, and behavior. Among them, the patients are one of the groups most influenced by the pandemic. Objective: The present research aimed to study the relationship of COVID-19 pandemic-induced disruption to patients' daily lives, ontological security, and patients' responses to prevent the spread of COVID-19, and explore the role of ontological security. Methods: This article was based on an online structured questionnaire study conducted among hospitalized patients in Taizhou Hospital of Zhejiang Province, Taizhou, China, from 8 July to 11 August 2021. We analyzed the data using the multivariate regression model and mediation analysis method. Results: The results showed that the higher the pandemic-induced disruption to inpatients' lives, the better behavior would be taken by hospitalized patients to prevent the spread of COVID-19, and the perceived scarcity of ontological security played a mediating role in this process. Higher pandemic-induced disruption to patients' lives increased the ontological insecurity which further, in turn, reduced patients' good practice toward measures to prevent the novel coronavirus. Conclusion: These findings provided direct evidence for the relationship between pandemic-induced disruption, scarcity of ontological security, and patients' prevention behavior. It suggested that there was a need to emphasize patients' ontological security. Overall, these findings suggested that it is important to emphasize the mental health among patients during the COVID-19 pandemic, and implement strategies to offer psychological support when needed.

Relationship between attitudes toward the effectiveness of vaccine, concerns about adverse reactions, and proactively taking SARS-Cov-2 vaccine for family among medical workers in Taizhou, China.

OBJECTIVES: Concerns about the safety of the SARS-CoV-2 vaccine have been a stumbling block in the promotion of vaccination uptake. Although many studies have focused on the investigation of people's intention to receive the COVID-19 vaccine, little attention has been paid to the underlying mechanism. This study explored whether concerns about the adverse reactions to the vaccine mediated the relationship between attitudes toward the effectiveness of the vaccine and proactively taking the vaccine for family. METHODS: Questionnaires were completed by 1,673 (39.9%, 1673/4191) healthcare workers at Taizhou Hospital, Taizhou, Zhejiang, China. Among these, 1,397 (83.5%) have received two doses of the SARS-Cov-2 vaccine. Mediation analysis approach was applied in this research. RESULTS: Attitudes toward the effectiveness of vaccines were positively correlated with proactively taking the COVID-19 vaccine for family. Additionally, concerns about the side effects to the SARS-Cov-2 vaccine mediated the relationship between attitudes toward the effectiveness of vaccines and proactively taking vaccines for family. CONCLUSION: The findings imply inextricable relationships among attitudes toward the effectiveness of the SARS-Cov-2 vaccine, fears about side effects to vaccines, and taking vaccines for family. It further suggested that the importance of highlighting the safety of vaccine in promotion of vaccination uptake.

The main decision-making competence for willingness-to-pay towards COVID-19 vaccination: a family-based study in Taizhou, China.

PURPOSE: This research aimed to explore individuals' willingness to pay (WTP) and studied the role of family decision makers in WTP for COVID-19 vaccines. METHODS: A self-administered online questionnaire evaluating the willingness of community residents to pay for booster vaccination of COVID-19 vaccine was conducted among families in a community in Taizhou, China. The logistic regression model was performed to identify the factors associated with WTP for the COVID-19 vaccines, and all data were analysed by R software, version 4.1.0. RESULTS: 44.2% and 43.7% of 824 community residents were willing to pay for the first two doses and the booster dose of the COVID-19 vaccine, respectively. Decision-makers were more willing to pay for both the first two doses and the boost dose of the COVID-19 vaccines, with OR (95%CI) being 1.75 (1.25-2.47) and 1.89 (1.34-2.67), respectively. Besides, participants' WTP for COVID-19 vaccines were also associated with their occupation and monthly household income. CONCLUSION: This study found that family decision-makers were more willing to pay for both the first two doses and the booster dose of COVID-19 vaccines in Taizhou, China. To improve the WTP for COVID-19 vaccines, public policy programs need to conduct a comprehensive cost-benefit analysis and focus on the role of family decision makers in vaccination.Key MessagesA study evaluating the willingness of community residents to pay for booster vaccination of COVID-19 vaccine was conducted among families in a community in Taizhou, China.Family decision-makers were more willing to pay for both the first two doses and the booster dose of COVID-19 vaccines.To improve the WTP for COVID-19 vaccines, public policy programs need to conduct a comprehensive cost-benefit analysis and focus on the role of family decision-makers in vaccination.

Knowledge, attitudes, and behaviors regarding COVID-19 among hospitalized patients in Taizhou, China.

Objection: This study investigated the relationship between the knowledge, attitudes, and behaviors among hospitalized patients regarding the prevention and control of COVID-19. Method: An online cross-sectional survey was conducted among hospitalized patients between July 8 and August 11, 2021, at a tertiary hospital in Taizhou, China. We performed descriptive analysis, t test, ANOVA (analysis of variance), and generalized linear regression modeling on the exported data. All data were analyzed using R software, version 4.1.0. Results: A total of 1185 valid questionnaires were returned. The average score of the participants on COVID-19 behaviors was 69.3 (SD = 15.6, with a full score of 87), indicating that most inpatients had good COVID-19 prevention and control behaviors. In addition, we found that inpatients with higher COVID-19 awareness also behaved better (B (95%CI) = 1.00 (0.73-1.27)) and were more willing to recommend vaccination to other people (OR (95%CI) = 1.11 (1.06-1.17)). Moreover, hospitalized patients who had positive attitudes toward implementing COVID-19 prevention and control measures had better practices (B (95%CI) = 2.50 (2.24-2.76)) and more willingness to recommend vaccinations (OR (95%CI) = 1.20 (1.14-1.26)). Conclusion: The research showed that the COVID-19 behaviors of hospitalized patients were positively associated with their knowledge and attitudes. These findings suggested that, for inpatients, hospitals should focus on teaching basic prevention knowledge of COVID-19. Targeted education initiatives should also be developed for patients from rural areas, especially those over 60 years of age, to help improve their knowledge and cultivate good prevention and control behaviors.

Physical condition, psychological status, and posttraumatic stress disorder among recovered COVID-19 subjects: A mediation analysis.

The physical condition of individuals who contracted COVID-19 had a profound influence on mitigating the physical and psychological impact of the disease and the symptoms of posttraumatic stress disorder (PTSD). Little attention has been focused on the influence of physical condition on PTSD among recovered COVID-19 subjects. This study explored the relationship between physical and psychological status and PTSD and the potential mechanisms. Questionnaires were completed by 73 (50.7%, 73/144) COVID-19 recovered subjects who were diagnosed in Taizhou, Zhejiang, China. We conducted a face-to-face survey from January 17 to March 10, 2020. The mediation analysis approach was applied in this research. Our data show that recovered COVID-19 subjects who were in better physical condition exhibited fewer psychological problems [B (95%CI), (-1.65 -3.04, -0.26)] and lower PTSD [B (95%CI), -6.13 (-9.43, -2.83)]. In addition, the worse the psychological status of recovered COVID-19 subjects was, the stronger the PTSD (B [95%CI], 0.58 [0.02, 1.14]). Moreover, psychological status could significantly mediate the impact of physical condition on PTSD (ß1θ2 = -0.87). Together, COVID-19 recovered subjects who have better physical condition could decrease their PTSD, and the worse the physical condition of COVID-19 recovered subjects would increase their psychological problems. Our finding about psychological status could significantly mediate the impact of the physical condition on PTSD might be useful for medical institutions and the government seeking to help with the follow-up rehabilitation training of recovered COVID-19 subjects.
