    Abstract Introduction Oropharyngeal squamous cell carcinoma (OPSCC) is increasingly prevalent and has significantly heterogeneous risks of survival for diagnosed individuals due to the inter-related risk factors. Precise prediction of the risk of survival for an individual patient with OPSCC presents a useful adjunct to therapeutic decision-making regarding the management of OPSCC. The aim of this systematic review, critical appraisal and meta-analysis is to assess prognostic prediction models for OPSCC and lay a foundation for future research programmes to develop and validate prognostic prediction models for OPSCC.Methods and analysis This protocol will follow the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocol statement. Based on predefined criteria, electronic databases including MEDLINE, Embase, Web of Science, the Cochrane Library and China National Knowledge Infrastructure (CNKI) will be searched for relevant studies without language restrictions from inception of databases to present. This study will systematically review published prognostic prediction models for survival outcomes in patients with OPSCC, describe their characteristics, compare performance and assess risk of bias and real-world clinical utility. Selection of eligible studies, data extraction and critical appraisal will be conducted independently by two reviewers. A third reviewer will resolve any disagreements. Included studies will be systematically summarised using appropriate tools designed for prognostic prediction modelling studies. Risk of bias and quality of studies will be assessed using the Prediction Model Risk of Bias Assessment Tool and the Transparent Reporting of a multivariable prediction model for individual prognosis or diagnosis. Performance measures of these models will be pooled and analysed with meta-analyses if feasible.Ethics and dissemination This review will be conducted completely based on published data, so approval from an ethics committee or written consent is not required. The results will ...

    Abstract Abstract Background College students generally have good knowledge about COVID-19 and may facilitate COVID-19 vaccination in family. The purpose of this study is to understand college students’ willingness to persuade their grandparents to initiate COVID-19 vaccination and the effect of their persuasion. Methods A combined cross-sectional and experimental study will be conducted online. In the cross-sectional study (Phase I), eligible participants are college students who are aged ≥ 16 years and have at least one living grandparent aged ≥ 60 years who has/have not completed the COVID-19 vaccination. Participants self-complete Questionnaire A to collect information on the socio-demographics of themselves and their grandparents, their knowledge about older adults’ COVID-19 vaccination, as well as Health Belief Model (HBM) and Theory of Planned Behavior (TPB) predictor variables. The primary outcome at Phase I is college students’ willingness to persuade grandparents to receive COVID-19 vaccines. Those who are willing to persuade grandparents and participate in a follow-up survey will be invited to participate in a randomized controlled trial (Phase II). At Phase II, eligible participants are those who have at least one living grandparent aged ≥ 60 years who completed the COVID-19 initial vaccination series but has/have not received a booster dose. At the baseline, participants self-complete Questionnaire B to collect information on individual grandparents’ COVID-19 vaccination status, attitude towards and intention to COVID-19 booster dose. Participants will then be randomly allocated 1:1 to either intervention arm (one-week smartphone-based health education on older adults’ COVID-19 vaccination plus two weeks’ waiting period) or control arm (three weeks’ waiting period). At the end of week three, participants in both arms self-complete Questionnaire C to collect information on their grandparents’ COVID-19 vaccination status. The primary outcome at Phase II is the uptake rate of COVID-19 booster dose among ...

    Abstract Abstract Shenzhen is a city of 22 million people in south China that serves as a financial and trade center for East Asia. The city has extensive ties to Hubei Province, the first reported epicenter of the coronavirus disease 2019 (COVID-19) outbreak in the world. Initial predictions suggested Shenzhen would experience a high number of COVID-19 cases. These predictions have not materialized. As of 31 March 2020 Shenzhen had only 451 confirmed cases of COVID-19. Contact tracing has shown that no cases were the result of community transmission within the city. While Shenzhen did not implement a citywide lockdown like Wuhan, it did put into place a rapid response system first developed after the severe acute respiratory syndrome (SARS) epidemic in 2003. In the wake of the 2003 SARS outbreak, Shenzhen health authority created a network for surveillance and responding to novel respiratory infections, including pneumonia of unknown causes (PUC). The network rapidly detected mass discussion about PUC and immediately deployed emergency preparedness, quarantine for close contacts of PUC. Five early actions (early detection, early reporting, early diagnosis, early isolation, and early treatment) and four centralized responses (centralized coordination by experts, centralized allocation of resources, centralized placement of patients, and centralized provision of treatment) ensured effective prevention and control. Tripartite working teams comprising community cadres, medical personnel and police were formulated to conduct contact tracing at each neighborhood and residential community. Incorporation of mobile technology, big data, and artificial intelligence into COVID-19 response increased accessibility to health services, reduced misinformation and minimized the impact of fake news. Shenzhen’s unique experience in successfully controlling the COVID-19 outbreak may be a useful model for countries and regions currently experiencing rapid spread of the virus.

    Abstract IntroductionMen who have sex with men (MSM) are increasingly using geosocial networking (GSN) mobile applications (apps) to socialize in the community. Our study aimed to compare sexual behaviors between app-using MSM (app users) and non-app-using MSM (non-app users), and evaluate the association between app use and sexually transmitted infections (STIs).MethodsEligible MSM were recruited from January to August 2017 in three metropolitan cities: Guangzhou, Shenzhen and Wuxi. A self-completed tablet-based questionnaire was collected about socio-demographic characteristics, sexual behaviors and app use. Blood samples were collected to test for HIV and syphilis. Rectal swabs taken by nurses and urine samples taken by participants themselves were collected to test for gonorrhea and chlamydia. Anogenital warts were checked by a clinician. Chi square tests and logistic regression were used to compare the prevalence of STIs and the characteristics between app users and non-app users.ResultsA total of 572 MSM were included in our analysis, 59.9, 25.7, and 23.4% MSM were recruited from Guangzhou, Shenzhen, and Wuxi, respectively. The majority of participants were 20–29 years old (61.7%). 89.0% of MSM had ever used at least one GSN app, and 63.8% MSM had anal intercourse (AI) partners found via apps. Among app users, 62.7% spent <30 min on apps per day on average in the past 6 months. Compared with non-app users, app users were more likely to have an education level of college and above [adjusted OR (AOR) 3.36, 95% confidence interval (CI) 1.65–7.03], have regular sex partners (2.40, 1.16–5.19), have two or more casual sex partners (2–5: 2.90, 1.21–6.90; ≥6: 13.91, 3.13–82.90), have condomless anal intercourse (CAI) with casual sex partners in the past 6 months (2.50, 1.28–5.04), do not know their last sex partners' HIV status (2.16, 1.13–4.21), have tested for HIV in the past year (2.09, 1.07–4.09) and be circumcised (4.07, 1.29–18.42). Prevalence of HIV (8.3 vs. 7.9%, P = 0.93), syphilis (6.9 vs. 11.1%, P = 0.34), ...

    Abstract Abstract Background To understand how human papillomavirus (HPV) screening results, HPV-related knowledge and attitudes are related to vaccination intention in three cost ranges and the actual vaccination behavior in a community sample of men who have sex with men (MSM). Methods MSM aged 20 years of age or older were recruited between October 2015 and May 2016 from community health centers that provide HIV testing and consultation services in Southern Taiwan and on social media. MSM were seen at baseline and again at 6 months after baseline in a cohort study. The baseline study included 253 individuals; 182 of them returned for the 6th-month follow-up. At each visit, MSM were asked to receive HPV screening and filled out a questionnaire. Structural equation modeling was used to test whether attitudinal factors and HPV screening results from the baseline affect their self-reported actual vaccine uptake at the in 6th-month follow-up. Results Our research included 171 participants from the cohort because they had full information of the study variables (mean ± SD age = 29.21 ± 6.18). Our model showed good model fit using indices such as the comparative fit index (value = 0.998) and root mean square error of approximation (value = 0.013). HPV knowledge can predict those who have intention to take up HPV vaccine no matter what the price (p = .02), and then predict vaccine uptake at the follow-up (p < .001). A positive HPV screening result can predict vaccine uptake at the follow-up (p = .004). Conclusion Our findings highlight the impact of vaccine price and HPV screening results on the intention and uptake of HPV vaccine. It is important to raise awareness of HPV in male populations. Clinicians and health educators should establish a safe and private environment for male patients for inquiring about HPV vaccine and HPV-related cancers.

    Abstract This study investigated the prevalence of and factors associated with behavioral intention to take up any type of HIV testing and HIV self-testing (HIVST) in the next six months among male migrant workers, who were at high risk of HIV infection, in Shenzhen, China. This was a secondary data analysis. A total of 363 subjects who had sexual intercourse with non-regular female sex partners and/or female sex workers in the past six months were selected. Logistic regression models were fitted for data analysis. About 16.5% of participants reported having used HIV testing in their lifetime and 12.7% for HIVST. Among the participants, 25.6% and 23.7% intended to take up any type of HIV testing and HIVST in the next six months, respectively. Significant factors associated with the behavioral intention to take up HIV testing and HIVST included individual-level factors based of the Health Belief Model (e.g., perceived benefit, perceived cue to action, perceived self-efficacy) and interpersonal-level factors (e.g., frequency of exposure to health-related content or HIV and STI-related content on short video apps). This study provided practical implications for designing interventions to increase the uptake of HIV testing and HIVST among migrant workers.

    Abstract Background: Men who have sex with men (MSM) living with HIV make up the majority of cases in the current Mpox outbreak. We aimed to investigate the perception of and vaccine readiness towards Mpox among MSM living with HIV in China. Methods: This cross-sectional online study was conducted from 10 August to 9 September 2022. Participants responded to survey questions about their socio-demographic information, HIV status, sexual behaviors, knowledge of Mpox, and attitudes towards Mpox vaccines. Results: A total of 577 MSM living with HIV participated in the study. A total of 37.6% expressed concerns about the Mpox epidemic in China, and 56.8% were willing to get the Mpox vaccine. Men who had > four sexual partners in the previous three months (aOR = 1.9 95% CI: 1.2–2.8 Ref: 0), had close contact with > four individuals in a day (3.1, 1.5–6.5 Ref: 0–3), were worried about the Mpox epidemic in China (1.6, 1.1–2.3 Ref: No), and believed that Mpox vaccines are safe (6.6, 2.7–16.4 Ref: No or not sure) and effective (1.9, 1.1–3.3 Ref: No) for people living with HIV were more likely to be willing to get the Mpox vaccine. MSM living with HIV with a high school education or below (0.5, 0.3–0.9 Ref: Postgraduate diploma), and sometimes (0.5, 0.3–0.8 Ref: Often), seldom, or never (0.5, 0.3–0.9 Ref: Often) followed news about Mpox were unwilling to get the Mpox vaccine. Conclusion: The ongoing Mpox pandemic has not attracted widespread concerns among MSM living with HIV in China. Having more sexual partners and close contacts, worrying about the Mpox epidemic, and believing in the vaccine’s safety and efficacy were predictors of their willingness to get the Mpox vaccine. Efforts should be made to raise awareness of the potential risk of Mpox in this at-risk population. Public health strategies should fully address predictors of vaccination willingness.

    Abstract Background: The World Health Organization (WHO) declared monkeypox a “public health emergency of international concern” on 23 June 2022. However, there is a lack of data on monkeypox perceptions among medical workers. The purposes of this study were to evaluate perceptions, worries about monkeypox, attitudes towards monkeypox vaccination and their correlates among medical workers in China. Methods: Data were collected from medical practitioners using an online survey questionnaire between September 1 and September 30, 2022 in China. All the subjects completed an online questionnaire including general characteristics, perceptions/knowledge/worries about monkeypox, and attitudes towards monkeypox vaccination. Logistic regression was employed to examine the correlates of perceptions, worries about monkeypox, and attitudes toward monkeypox vaccination. Results: In total, this study sample included 639 medical workers. The mean age was 37.9 ± 9.4 years old. Approximately 71.8% of individuals reported perceptions of monkeypox, 56.7% worried about monkeypox, and 64.9% supported the promotion of monkeypox vaccination. Medical workers who were older than 50 years (aOR 3.73, 95%CI 1.01–13.85), worked in the Infectious Diseases/Dermatology/Venereal Diseases departments (3.09, 1.61–5.91), and provided correct answer to monkeypox transmission route (10.19, 5.42–19.17) were more likely to know about monkeypox/monkeypox virus before investigation. 30.7% reported that they were more worried about monkeypox than the coronavirus (COVID-19). Participants reported that the key population most in need of monkeypox vaccination were health practitioners (78.2%) and people with immunodeficiency (74.3%), followed by children (65.4%) and older adults (63.2%). Conclusion: Awareness of monkeypox was high and attitude towards the promotion of monkeypox vaccination was positive among medical staff in China. Further targeted dissemination of monkeypox common knowledge among health care providers might improve their precaution measures and ...
