Background
With healthcare's accelerating digital transformation and expanding data-sharing capabilities, it is essential to uphold Indigenous Data Sovereignty (IDSov)—which affirms Indigenous ownership and authority over health data relating to Indigenous communities. Indigenous Data Governance (IDGov) provides the mechanisms through which IDSov is enacted, ensuring Indigenous Peoples lead decisions about how data are collected, accessed, and used. Our research investigates a local enactment of IDGov, discussing how custodial stewardship is enacted in data-sharing arrangements between an Aboriginal and Torres Strait Islander community-controlled health organisation and a government birthing facility. The research aimed to understand Aboriginal and Torres Strait Islander service users' and health workers' perspectives on how/whether to share data between services.
Methods
Led by a community-controlled organisation, the study used Indigenous methodologies, including ‘yarning’—a traditional knowledge-sharing practice. An Aboriginal researcher conducted yarns with Aboriginal and/or Torres Strait Islander staff and perinatal service users. Collaborative analysis was undertaken using an adapted ‘Thought Ritual’, an Indigenous analytical framework.
Findings
Analysis identified four domains: 1) Power and Control in Data Sharing—Data sharing can shift power dynamics, affecting sovereignty and community control, 2) Safety Concerns—Participants cited legal, cultural, and psychosocial risks tied to stigma and systemic racism, 3) Ability to Do My Job—Limited data access can hinder effective service delivery, and 4) Not Everything Should Be Shared—There is a clear preference for consent-based, selective data sharing.
Interpretation
Honouring Indigenous perspectives in data-sharing arrangements is an ethical obligation. In perinatal settings, upholding custodial stewardship helps safeguard sovereignty, safety, and equitable outcomes.

Asia, home to nearly 60% of the world's population, is central to global demographic change. Fertility trajectories shape population growth, aging, and decline, with implications for labor supply, economic development, family structures, and caregiving. Studying these patterns offers critical insights into the future of population size, structure, and human potential both regionally and globally. This paper addresses gaps in the largely snapshot, country-specific literature by providing a six-decade comparative overview of fertility trends in East, Southeast, and South Asia, with emphasis on their social determinants. Fertility is shaped not only by individual choice or biology but also by broader socioeconomic, cultural, and policy contexts that influence proximate factors of fertility such as union patterns, contraception, postpartum infecundability, and abortion. We identify distinct regional trajectories of fertility decline, examine their underlying drivers, assess the applicability of prevailing theories, and propose an Asymmetric Adaptation Framework to explain Asia's fertility transitions. While socioeconomic development and ideational change have shaped fertility behavior, cultural factors—such as religion, colonial legacies, kinship systems, and family policy—are pivotal in Asia. Certain trends cannot be explained by socioeconomic development alone, reflecting deeper historical and cultural roots. The Asian experience highlights the limits of prevailing Eurocentric, unidirectional theories and underscores the need for regionally grounded explanations that account for the interplay of structural forces, cultural norms, historical contexts, and policy in shaping fertility decline.

Device-detected atrial fibrillation (DDAF), including atrial high-rate episodes recorded at a cardiovascular implantable electronic device and subclinical atrial fibrillation detected by insertable cardiac monitor and smart wearables, poses an increasing challenge in stroke prevention. Although oral anticoagulants (OACs) are effective in clinical AF, their benefit-risk balance in DDAF remains uncertain. In response, the Asia Pacific Heart Rhythm Society (APHRS) proposes the 4S-DDAF approach (Strip documentation and longest AF duration, Symptoms, Stroke [ischemic] history, and Score) to guide anticoagulation decisions. This approach integrates electrogram review, symptom assessment, history of ischemic stroke or transient ischemic attack (TIA), and CHA2DS2-VASc scoring, emphasizing individualized care. OACs are recommended for patients with AF episodes ≥24 h, prior stroke/TIA, CHA2DS2-VASc score ≥4, or vascular disease. In patients not meeting these thresholds, close monitoring and risk factor management are advised. The 4S-DDAF approach provides a practical and evidence-informed strategy for clinical decision-making in the management of DDAF.

Background
The World Mental Health Hong Kong (WMHHK) Study aims to estimate 12-month and 30-day prevalence, persistence, severity, and correlates of DSM-5 anxiety, mood, and externalising disorders in Hong Kong, a densely populated city impacted by consecutive population-level stressors, including social unrest and the COVID-19 pandemic.
Methods
Face-to-face interviews, either in-person or video-based online, were conducted from November 2022 to March 2024 with a population-representative sample of 3053 adults aged 18 years and above. Diagnostic assessment utilised the World Mental Health Composite International Diagnostic Interview for DSM-5 (CIDI-5), evaluating ten mental disorders: anxiety (panic disorder, generalised anxiety disorder, post-traumatic stress disorder, obsessive-compulsive and related disorders), mood (major depressive disorder, persistent depressive disorder, bipolar spectrum disorders), and externalising (intermittent explosive disorder, alcohol use disorder, substance use disorder) disorders. Persistence was defined as 12-month prevalence among lifetime cases and 30-day prevalence among 12-month cases. Sociodemographic correlates were analysed using multivariable logistic regression.
Findings
Twelve-month and 30-day prevalence of any DSM-5 mental disorder were 10.6% (95% CI: 9.5–11.8) and 7.8% (95% CI: 6.7–8.9), respectively. Twelve-month prevalence was highest for anxiety disorders (8.0%, 95% CI: 7.1–8.9), followed by mood (4.3%, 95% CI: 3.4–5.2) and externalising (1.7%, 95% CI: 0.9–2.4) disorders. Twelve-month persistence among lifetime cases was 49.0%, overall and higher for anxiety (55.6%) than mood (39.0%) or externalising (35.3%) disorders. Younger and middle-aged adults, and who were not currently married, had elevated risks, while lower education was associated with greater disorder severity. Comorbidity was associated with increased persistence and severity across disorders.
Interpretation
This study shows a substantial mental health burden in Hong Kong during the post-pandemic period, highlighting the need for tailored public mental health programmes to address urban stressors in this unique context.

Background
Globally, sepsis remains a substantial public health concern. To inform policy development and interventions for sepsis prevention, treatment, and surveillance in Aotearoa New Zealand (Aotearoa), we describe population-level epidemiological trends in hospitalised sepsis and mortality over two decades by major sociodemographic characteristics.
Methods
We undertook a retrospective, population-based descriptive study of all sepsis-associated hospitalisation (SAH) in Aotearoa between 2000 and 2019 using previously published case identification strategies and International Classification of Diseases, Tenth Revision (ICD-10) codes to identify SAHs in the National Minimum Dataset. Incidence and mortality rates, and case fatality risks were calculated along with analyses of trends over the 20-year observation period. Rate estimates were standardised to the age structure of the total population identified in the 2018 New Zealand Census.
Findings
We identified 266,105 unique SAH cases and 27,402 associated deaths, with an average age-standardised incidence rate (ASIR) of 320.4 admissions per 100,000 population and an age-standardised mortality rate (ASMR) of 34.2 deaths per 100,000 population. An average annual ASIR increase of 4.5% was observed, from 217.3 admissions in 2000 to 386.9 admissions per 100,000 population in 2019. ASMR decreased annually from 37.1 deaths in 2000 to 31.3 deaths per 100,000 population in 2019. Case fatality risk decreased from 15.9 deaths in 2000 to 8.1 deaths per 100 admissions in 2019, primarily driven by improvements in patient survival in ≥40-year age groups. Significant SAH incidence and mortality disparities were observed between patient populations, particularly by age, ethnicity and socioeconomic deprivation. Māori and Pacific Peoples had SAH incidence rates that were 1.7 and 2.3 times, respectively, higher than those of NMPA ethnicity, and had mortality rates that were 1.6 and 1.7 times higher. Similarly, those living in areas of high socioeconomic deprivation were twice as likely to develop SAH, and their SAH mortality rate was twice as high as that of those living in areas of the least socioeconomic deprivation.
Interpretation
Sepsis is common in Aotearoa and makes a substantial contribution to population mortality. Significant variation in incidence and mortality rate estimates was observed between patient populations, with higher rates in those <1 year and ≥70 years, of Māori or Pacific ethnicity, and those living in areas of high socioeconomic deprivation. Our findings highlight the burden of SAH and the need for targeted interventions to address sepsis prevention, surveillance and support for sepsis survivors in Aotearoa.

Background
Healthcare-associated infections (HAIs), complicated by antimicrobial resistance continue to affect all countries with unprecedented threat, especially for developing countries. Our objective was to explore the epidemiological features, spatiotemporal heterogeneity and associated factors of HAIs and HAI related multi-drug resistant organisms (MDROs) in China.
Methods
We used national surveillance data that were collected from 6867 sampled hospitals during 2015–2019 to determine the annual incidence of HAIs, key HAI-related quality indicators and associated factors.
Findings
During 2015–2019, total of 4,959,230 HAIs were reported in sampled hospitals in China, with the overall incidence and prevalence estimated as 1.1 and 2.3 per 100 inpatients, which showed decline trend over time. Carbapenem-resistant Acinetobacter baumannii (CRAB) had the highest overall detection rate (51.1%), followed by methicillin-resistant Staphylococcus aureus (MRSA) (31.0%), carbapenem-resistant Pseudomonas aeruginosa (CRPA) (22.8%), and carbapenem-resistant Klebsiella pneumonia (CRKP) (12.4%). Detection rates of MRSA, carbapenem-resistant Escherichia coli (CREC), and vancomycin-resistant Enterococcus faecium (VREfm) reduced, in contrast with an increasing trend for CRKP. Higher risk of HAIs was associated with hospitals located in urban areas (incidence rate ratio [IRR]: 1.39, p < 0.001), in regions with higher GDP per capita (IRR: 1.03, p < 0.001), with more beds (IRR: 1.64 and 2.16 for 500−1500 and ≥ 1500 beds respectively, p < 0.001), as well as in south region of China (IRR: 1.23, p < 0.001). The reduced annual rates of HAIs were observed after 2017 (IRR: 0.92, p < 0.001), when 12 new standards targeted for HAIs were implemented.
Interpretation
The study increases the understanding of HAIs and antimicrobial resistance. It highlights high-risk areas of HAIs and MDROs of concern, where targeted measures to continuously enhance management and policies implementation of HAIs are needed.

Background
Type 1 diabetes (T1D) is an autoimmune condition affecting children. We aimed to investigate the costs and cost-effectiveness of potential national childhood screening strategies for T1D compared to no screening (usual care).
Methods
Screening costs were obtained from trial-based estimates. A Markov microsimulation model was developed to identify the most cost-effective childhood T1D screening strategy. The three screening strategies modelled were: Strategy 1) newborn genetic risk-stratification with bloodspot sampling, followed by autoantibody screening in at-risk children; Strategy 2) infant genetic risk-stratification using saliva sampling, followed by autoantibody screening in at-risk children; Strategy 3) population-wide autoantibody screening at two childhood ages. The model tracked 100,000 individuals from birth to 30 years of age. One-way and probabilistic sensitivity analyses were conducted.
Findings
Newborn bloodspot genetic risk-stratified screening (strategy 1) was the most cost-effective strategy. Incremental cost-effectiveness ratios (ICERs) were $50,682 per quality-adjusted life year (QALY) gained for strategy 1, $85,440 per QALY gained for strategy 2, and $133,285 per QALY gained for strategy 3. In the optimal strategy (strategy 1), the cost was $480,798 per screen-detected T1D and $12,183 per episode of diabetic ketoacidosis avoided. Results were sensitive to changes in time horizon, discount rates, and cost of the screening tests.
Interpretation
Of the three modelled T1D screening strategies, newborn bloodspot genetic risk-stratified screening was the most cost-effective. Varying cost inputs may change this hierarchy. Our economic evaluation will be useful for informing future T1D childhood screening policy in Australia and other high-income countries.
