Theory-based chatbot for promoting colorectal cancer screening in a community setting in Hong Kong: study protocol of a randomised controlled trial
Background
Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer mortality worldwide. Despite the organised CRC screening programme, the uptake rate of the population-based CRC screening was still low. Thus, we will conduct a randomised controlled trial in a community setting to evaluate the effectiveness of a theory-based chatbot in promoting CRC screening uptake.
Methods and analysis
A total of 500 eligible participants will be randomly assigned to a WhatsApp Messenger-initiated chatbot outreach group or a standard text reminder group at a ratio of 1:1. The intervention group will deliver Chinese culturally tailored education texts and videos developed based on the Health Belief Model and the Trans-Theoretical Model. The control group will deliver a standard text reminder of information about the Hong Kong organised CRC screening programme. In addition to the baseline assessment and postintervention assessment, all subjects will be followed up for 3 months and 6 months, respectively. The primary outcome will be the CRC screening uptake rate at the 3 month and 6 month follow-up. The secondary outcomes will be the intention to undergo CRC screening uptake, time interval to participate in and complete screening after recruitment, and reasons for not participating in screening at the 3 month and 6 month follow-up. Quantitative data will be analysed using Student’s t-test, Pearson’s 2 test or Fisher’s exact test. Qualitative data will be analysed by thematic analysis.
Ethics and dissemination
Ethical approval of this trial was granted by the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (2022.614). Written informed consent will be obtained from study participants before enrolment. The findings will be disseminated through peer-reviewed journals.
Trial registration number
The study was registered on clinicaltrials.gov (NCT06192862).
Understanding Predictors of Lifelong Initiation and Follow-up Treatment for adolescents and youth living with HIV (UPLIFT): an integrated prospective cohort in Eastern Cape, South Africa
Purpose
Adolescents living with HIV (ALHIV) are a priority population for achieving global HIV prevention and treatment targets but experience poorer outcomes than adults. Long-term follow-up is essential to understand their transition into adulthood. By linking self-reported survey data with routine laboratory records, we established a social science clinical cohort of ALHIV South Africa’s Eastern Cape to explore factors shaping their long-term health and well-being.
Participants
Eligible participants were adolescents who were part of a three-wave quantitative cohort of ALHIV and not living with HIV (2014–2018) and had consented (adolescent and caregiver) to having their self-reported interviews linked with routine health records (n=1563). Adolescents were recruited into the existing three-wave cohort through clinic and community-based methods (97% enrolment, >90% retention over three waves). Between 2019 and 2022, we abstracted laboratory test records from the National Health Laboratory Services database for all eligible participants, with matching based on demographic variables. Individuals with at least one HIV-related record form our ‘lifelong social science cohort’, a total of 956 ALHIV (852 of 1107 ALHIV and 104 of 456 HIV-uninfected).
Findings to date
A total of 32 886 laboratory test records from 2004 to 2023 were matched through three rounds of data extraction, using iteratively refined record-linking searches. Most records were viral load (8864) and CD4 count (6801) results, with a median of 10 (IQR: 7–14) and 8 (IQR: 5–11) tests per matched adolescent, respectively. Overall, 956 of 1563 adolescents (61%) were successfully linked to laboratory data, including 852 of 1107 (77%) ALHIV. Analysis of the matched cohort survey-laboratory data provided several insights. Self-reported antiretroviral therapy adherence was strongly associated with viral suppression, even after adjusting for covariates. The strongest predictors of suppression were not reporting missed doses in the past 3 days, past week and not missing clinic appointments in the past year. Among adolescent girls and young women living with HIV, access to safe and affordable facilities, and kind and respectful staff were associated with a higher likelihood of multiple improved HIV-related outcomes, including viral suppression. Exposure to sexual and intimate partner violence predicted worse viral load outcomes among adolescents.
Future plans
This integrated prospective cohort provides an opportunity to characterise long-term HIV treatment outcomes among ALHIV in Africa. We will investigate how individual, familial, community and healthcare experiences in childhood, and adolescence shape these outcomes. Since the COVID-19 pandemic happened during the period of matched data, we will also investigate the potential effect of the COVID-19 pandemic on adolescent HIV treatment outcomes, with potential subgroup analyses for individuals with available COVID-19-related results.
Assessing the experimental EuroQol toddler and infant populations (EQ-TIPS) descriptive system: a protocol integrating discrete choice experiment (DCE) surveys in instrument development
Introduction
The experimental EuroQol Toddler and Infant Populations (EQ-TIPS) instrument is currently under development as a health-related quality of life (HRQoL) measure for toddlers and infants aged 0–36 months. Using this protocol, researchers can conduct surveys with discrete choice experiments (DCEs) that examine the key properties of HRQoL instruments, specifically whether severity aligns with preferences across each attribute and the extent to which attributes influence choices. To demonstrate this protocol, we will conduct two waves of DCE surveys using different choice tasks and a common scenario (a 1-month health episode for a 1-year-old child).
Methods and analysis
In the first wave (a general population sample of 400 Australian adults; 14 kaizen tasks each), respondents will view a single EQ-TIPS-five-level (v3.0) profile for each task and be asked to make a series of choices that sequentially alleviate the child’s health problems. Using this exploratory evidence, we will assess whether EQ-TIPS severity aligns with preferences and the extent to which each attribute level influences choices (ie, main effects). In the second wave (1000 Australian adults; 28 paired comparisons), respondents will see two EQ-TIPS profiles for each task and be asked to choose between them. Using this confirmatory evidence, we will compare the main effects and their uncertainty by wave. For each DCE, we will estimate a main-effects conditional logit model and test for differences in effects using cluster bootstrap techniques. As sensitivity analyses, we will evaluate the effects of task sequence, attribute order and sample size on uncertainty in each wave.
Ethics and dissemination
The independent review board at Includovate evaluated the application for ethical clearance and approved the study on 19 February 2025. To disseminate our findings, we will prepare multiple manuscripts for publication in peer-reviewed journals and present highlights at scientific meetings, such as the EuroQol Plenary Meeting and the International Academy of Health Preference Research.
Development and preliminary evaluation in community mental health teams of a cervical screening informed-choice tool for women with severe mental illness in England: a mixed-method study
Objectives
Women with severe mental illness (SMI) face barriers to cervical cancer screening, leading to lower participation and poorer outcomes. This research aimed to develop and test an informed-choice tool to help women with SMI make informed decisions about screening attendance.
Design
The tool was developed using a realist review of physical health interventions and a systematic review of informed-choice tools for people with SMI. A mixed-methods approach informed its development. Usability and acceptability were assessed through semistructured interviews and the think-aloud method with service users (n=18), clinicians (n=16) and key informants. A preliminary proof-of-concept (n=25) evaluated the impact on decisional conflict—the uncertainty around making value-sensitive choices.
Setting and participants
Conducted in two National Health Service (NHS) Mental Health Trusts (urban and rural). Participants included women with SMI accessing secondary mental healthcare, clinicians and service user groups. A key informants’ group guided clinical content.
Intervention
A cervical screening informed-choice leaflet and an accompanying video.
Results
The tool was usable and acceptable, especially for women overdue or never screened. It may reduce decisional conflict and increase screening uptake, potentially improving survival. An National Institute for Health and Care Research (NIHR)-funded feasibility trial (Improving uptake of cervical screening in people with severe mental illness (OPTMISE)) is underway. The current UK government guidance on Support for people who find it hard to attend cervical screening due to having a mental health condition or having experienced trauma or abuse is based on this research.
Conclusions
Future research may involve further assessments of the real-world impact of the tool and its adaptation to other health-related decisions.
ProVag: the effect of oral probiotics on the vaginal microbiota composition in women receiving medical assisted reproduction in a Dutch fertility clinic – protocol of a randomised, placebo-controlled, double-blind study
Introduction
Differences in the profile of the vaginal microbiota (VMB) have been associated with pregnancy rates after medical assisted reproduction (MAR) such as in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). Monitoring the VMB profile of IVF patients creates an opportunity to identify the best window for IVF treatment and embryo transfer. The ReceptIVFity test is a predictive test that assesses the chances of becoming pregnant in women undergoing IVF treatment based on the VMB composition. A VMB profile dominated by beneficial strains, most notably Lactobacillus species, is associated with increased pregnancy chances. However, to date, limited evidence is available on the effect of active modification strategies to facilitate the modulation of the VMB profile to help restore a VMB dominated by Lactobacillus species.
Methods and analysis
This is a randomised, placebo-controlled, double-blind intervention study. The study will involve 1:1 randomisation to one of the two arms: oral probiotic or placebo. Vaginal and rectal swabs will be collected at intake and 4, 6 and 8 weeks after the start of the treatment. Our objective is to determine if oral probiotic treatment improves the VMB profile of IVF patients from a low to a medium/high ReceptIVFity score, compared with placebo treatment. Secondary outcomes are: the potential of the bacterial strains in the oral probiotic to be detected in the vaginal tract and/or in the gut, and if the treatment leads to an increased ongoing pregnancy rate after IVF.
Ethics and dissemination
Ethical approval was obtained by the local medical ethical review committee at the Maastricht University Medical Centre. Findings from this study will be published in a peer-reviewed scientific journal and presented at one or more scientific conferences.

Evaluating an intervention to promote access to mental healthcare for low language proficient migrants and refugees across Europe (MentalHealth4All): study protocol for a pretest-post-test cross-national survey study
Background
Migrants and refugees with low language proficiency (LLP) in the dominant language of their host country have a higher risk of suffering from certain mental health disorders compared with non-migrant populations. They are also more likely to experience a lack of access to mental healthcare due to language-related and culture-related barriers. As part of the MentalHealth4All project, a digital multilingual communication and information platform was developed to promote access to mental healthcare for LLP migrants and refugees across Europe. This paper describes the study protocol for evaluating the platform in practice, among both health and/or social care providers (HSCPs) and LLP migrants and refugees.
Methods and analysis
We will conduct a pretest–post-test cross-national survey study to evaluate the platform’s effect evaluation (primary objective) and process evaluation (secondary objective). The primary outcomes (measured at T0, T2 and T3) are four dimensions of access to mental healthcare services: availability, approachability, acceptability and appropriateness of mental healthcare. Secondary outcomes (measured at T2) are: actual usage of the platform (ie, tracking data), perceived ease of use, usefulness of content, comprehensibility of information, attractiveness of content and emotional support. Participants will be recruited from nine European countries: Belgium, Germany, Italy, Lithuania, the Netherlands, Poland, Slovakia, Spain and the UK. Using convenience sampling through professional networks/organisations and key figures, we aim to include at least 52 HSCPs (ie, 6–10 per country) and 260 LLP migrants (ie, 30–35 per country). After completing a pretest questionnaire (T0), participants will be requested to use the platform, and HSCPs will participate in an additional personalised training (T1). Next, participants will fill out a post-test questionnaire (T2) and will be requested to participate in a second post-test questionnaire (T3, about 6–8 weeks after T2) to answer additional questions on their experiences through a brief phone interview (T3 is optional for migrants/refugees).
Ethics and dissemination
For all nine countries, the ethical review board of the participating university (hospital) has assessed and approved the protocol. If successful, the MentalHealth4All platform will be made publicly available to help improve access to mental healthcare services, as well as HSCPs’ cultural competencies in delivering such services, for any LLP migrants and refugees across Europe (and beyond). Findings will also be disseminated through peer-reviewed journals and conferences.

Determinants of enrolment rate in 397 clinical trials for healing diabetic foot ulcers: a systematic review
Objectives
Diabetes mellitus (DM) affects over 422 million individuals globally. Diabetic foot ulcers (DFUs) stand out as a challenging complication of DM, affecting up to 34% of individuals with DM. Despite the prevalence of DFUs, clinical trials for DFUs often face slow and insufficient patient recruitment. We aimed to identify key determinants that impact subject recruitment rates in DFU clinical trials.
Design
Systematic review.
Data sources
ClinicalTrials.gov and PubMed were searched to identify DFU clinical studies published from 1 January 1990 to 9 April 2025.
Eligibility criteria
We included English-language publications of clinical trials aimed at healing DFUs that reported enrolment numbers, duration of enrolment and number of study centres.
Data extraction and synthesis
Records were extracted and subjected to two independent rounds of review by five authors (LZ, SP, RN, HL-T, and RK). Data were pooled and analysed using negative binomial regression, Kaplan-Meier methods and Cox proportional hazards models. Study enrolment and site enrolment rates, as well as time to complete study enrolment, were analysed. Between-study heterogeneity was assessed using the likelihood ratio test.
Results
397 trials involving 31 955 participants were included. On average, DFU studies enrolled 4.24 patients per month (median: 1.65). US-based studies had slower recruitment than non-US studies, with a mean enrolment rate of 1.51 patients per site per month (median: 0.58). The average time to complete enrolment was 1.28 years. Studies that employed a higher number of study sites, were conducted outside the USA, studied behavioural or dietary supplement interventions, and began enrolment more recently, were more likely to have a higher enrolment rate. Longer time to complete enrolment was associated with a larger number of study sites, trials involving at least one US site, earlier starting enrolment year, and longer follow-up duration.
Conclusions
These findings have potential practical implications for the design and conduct of future DFU trials.
Duration of COVID-19 symptoms in children: a longitudinal study in a Rio de Janeiro favela, Brazil
Objectives
COVID-19 in children is generally of short duration, but some may take longer to recover. This study investigated the time to symptom resolution following SARS-CoV-2 infection among children in a community setting on the outskirts of an urban centre in Brazil.
Design
Prospective cohort study.
Setting
This is a community-based cohort of children living in Manguinhos, a favela in Rio de Janeiro. The cohort was followed through home visits and telephone monitoring of symptoms. The analysis focused on symptomatic children from this cohort with confirmed SARS-CoV-2 infection. Recovery time was defined as the interval between the first date with symptoms and the first date without symptoms following a positive SARS-CoV-2 test.
Participants
A total of 1276 children (boys and girls aged 2–
Patients experience of self-testing measuring total white cell count and C reactive protein during treatment at home with antibiotics: a qualitative study
Objective
To explore patients’ experiences and preferences of self-testing using white cell count point-of-care test (POCT) and C reactive protein POCT during antibiotic treatment at home.
Setting
A University Hospital in the Region of Zealand (DK).
Participants
10 inpatients treated with antibiotics who were discharged from hospital to continue antibiotic treatment at home. They were trained in the hospital supervised by research personnel before self-testing at home.
Design
An explorative qualitative study using thematic analysis.
Results
The participants considered the self-testing beneficial, mainly due to not having to travel to get a blood test drawn, the rapid test time and the ability to closely monitor their treatment. The participants perceived that self-testing at home would make them feel more in control of their disease and would give them the ability to live a more normal life. Moreover, self-testing at home showed to be feasible for some patients but with barriers to overcome, such as the ability to use technology and cognitive challenges.
Conclusions
Our study showed that self-testing at home was feasible for some patients, provided they received thorough training at the hospital ensuring that participants were able to conduct the self-testing and use the smartphone technology before transitioning to their home. This could help reduce barriers to home self-testing by highlighting its benefits and emphasising the need for adequate patient guidance and support.
Associations between optimism and mental health in postradiotherapy cancer survivors: a cross-sectional survey study
Objectives
Cancer patients often experience psychological distress, while optimism has been identified as a protective factor. However, the mental health of postradiotherapy cancer survivors and its association with optimism remain largely unexplored. This study assesses the mental health status and optimism levels of postradiotherapy cancer survivors and evaluates their associations.
Design
Cross-sectional survey study.
Participants
114 Hong Kong cancer survivors who (1) were aged 18 years or above and (2) had received radiotherapy for their cancer treatment and finished the radiotherapy within the previous 3 years (2021–2024).
Outcome measures
Mental health was assessed using the Chinese Depression, Anxiety and Stress Scale, and optimism was measured using the Revised Life Orientation Test. Correlation and regression analyses were used to examine the associations between these measures.
Results
Participants reported overall low optimism with mild to moderate depression, anxiety and stress. Strong negative correlations were identified between optimism and depression (r=–0.833, p
