Introduction
Cervical cancer remains a significant public health concern in Singapore, with current screening rates at 43%, well below the national target of 70%. In 2019, human papillomavirus (HPV) DNA testing was introduced into the national cervical cancer screening programme, but barriers to participation include embarrassment, privacy concerns and discomfort with clinician-sampled tests. Self-sampled HPV DNA testing offers a promising alternative by providing more privacy and convenience. This study aims to evaluate the impact of including self-sampled HPV DNA testing as an alternative to clinician-sampling on screening uptake, clinical outcomes and cost-effectiveness in primary care.

Methods and analysis
This pragmatic, open-label, two-arm randomised controlled trial employs a Zelen design. A total of 650 women aged 30–69 who are due for cervical cancer screening will be recruited from National Healthcare Group Polyclinics in Singapore. Participants will be randomly assigned to either the intervention arm (offering both self-sampling and clinician-sampling) or the usual care arm (clinician-sampling only). The primary outcome is the proportion of participants in each arm detected with high-risk HPV. Secondary outcomes include the proportion of participants in each arm who undergo cervical cancer screening (uptake), are referred for colposcopy and are detected with CIN 2/3 or cervical cancer, as well as cost-effectiveness. Acceptability and feasibility of self-sampling will be evaluated through post-screening questionnaires.

Ethics and dissemination
Ethical approval was granted by the National Healthcare Group Domain Specific Review Board. Study results will be disseminated through peer-reviewed journals, healthcare conferences and shared with policymakers to guide potential inclusion of self-sampling in Singapore’s national cervical cancer screening programme. Findings from this trial will provide crucial evidence for the potential inclusion of self-sampling in Singapore’s national cervical cancer screening programme, which could increase screening rates and improve public health outcomes.

Introduction
Preterm birth is a significant contributor to pregnancy-related morbidity and mortality, particularly affecting black women. Racism is a key driver of perinatal inequities, but mechanisms remain unclear. Epigenomics research offers promise in understanding how environmental exposures, including racism, influence gene expression and adverse pregnancy outcomes. We present our study protocol describing how we will investigate the interactive effects of individual- and structural-level racism on preterm birth within and across black and white women, characterise the blood-based methylome of black pregnant women and identify whether DNA methylation mediates the association between multilevel racism and preterm birth in black women.

Methods and analysis
We will conduct a secondary analysis of data from 6843 participants in the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be (nuMoM2b), a longitudinal, prospective cohort study (2010–2014). Individual-level racism was collected using the Experiences of Discrimination scale. Structural racism measures include racial residential segregation, income and racial polarisation, political participation, judicial treatment, homeownership and employment. These measures will be calculated using geocoded participant addresses and publicly available census data for black and white populations. Epigenome-wide methylation analyses will be conducted on stored DNA for all enrolled black women using the EPIC 2.0 BeadChip. Preterm birth was determined by abstraction from participant electronic health records. We will determine the joint effects of individual and structural racism on preterm birth, characterise DNA methylation profiles associated with preterm birth among black women and explore the mediating role of DNA methylation in the association between multilevel racism and preterm birth.

Ethics and dissemination
Study procedures were approved by the Columbia University Institutional Review Board (#AAAU0215). This study aims to fill critical knowledge gaps regarding the role of racism and epigenomics in preterm birth among black women.

This prospective multicenter study including individuals with hematuria evaluates the performance of a urinary DNA methylation test in identifying patients with high-grade or invasive bladder cancer.
