Background
Since 1992, when recombinant hepatitis B vaccine was introduced in China, government health officials have used nationally representative serological surveys to monitor progress in prevention and control of hepatitis B. In 2020, we conducted the fourth seroepidemiological survey, which for the first time included medical evaluation of the clinical status of HBsAg positive subjects over the age of 15 and their medical management. We report survey results in comparison with the three previous surveys.
Methods
Consistent with previous national surveys, the 2020 survey used a stratified, three-stage cluster random sampling method to select for evaluation 1-69-year-olds in 120 national disease surveillance points. Blood samples were tested for HBsAg, anti-HBV surface antigen (anti-HBs), and anti-HBV core antigen (anti-HBc) in the National Hepatitis Laboratory of the Institute for Viral Disease Control and Prevention of China CDC. HBsAg positive subjects aged ≥15-year were evaluated for evidence of liver disease, and through face-to-face questionnaire-based survey, we determined the healthcare management cascade of HBV-infected individuals.
Findings
HBsAg prevalence in 1–69-year-olds was 5.86%; in children 1–4 years of age, seroprevalence was 0.30%; 75 million people were living with HBV nationwide. Among HBsAg-positive individuals 15 years and older, expert medical examination found that 78.03% were HBsAg carriers with no evidence of liver damage, 19.63% had chronic HBV with liver enzyme abnormalities, 0.84% had evidence of cirrhosis, and 0.15% had evidence of liver cancer. 59.78% of HBsAg + individuals were aware that they were positive before the survey, 30 million were unaware; 38.25% of those who knew they were positive (17 million) had medical indications for antiviral treatment, and 17.33% of these individuals (3 million) were being treated with antivirals.
Interpretation
The decline in HBsAg prevalence in the general population, from 9.72% in 1992 to 5.86% in 2020, and in 1–4-year-olds from 9.67% in 1992 to 0.30% in 2020, shows progress that continues on track toward WHO targets for prevention of new infections. Implementation of acceptable strategies to identify infected individuals and offer long-term medical monitoring and management will be important to prevent complications from hepatitis B infection and for meeting WHO cascade-of-care targets.

Background
Invasive fungal disease (IFD) is a significant complication for children receiving treatment for leukaemia, contributing to morbidity and mortality. Recent regional paediatric epidemiological IFD data are lacking. Additionally uncertainty remains regarding the optimal prophylactic approach in this context.
Methods
In a multi-centre Australian cohort study of children diagnosed with de novo acute leukaemia between 1st January 2017 and 30th June 2020, we characterised antifungal prophylaxis prescribing and IFD prevalence. Impact of antifungal prophylaxis was assessed using Kaplan Meier curves and Cox-proportional hazards regression adjusting for known IFD risk factors.
Findings
A total of 434 children were included (47.2% female; median age 5.0 years, median follow-up 240 days). This cohort included 351 children with ALL (214 high-risk [HR-ALL]; 137 standard-risk [SR-ALL]), and 73 with AML. The prevalence of proven/probable IFD was 6.8% for AML, 14.0% for HR-ALL and 4.4% for SR-ALL. A mould was implicated as the causative pathogen in almost two thirds of cases. Antifungal prophylaxis was prescribed in 98.7% of chemotherapy cycles for AML, 56.7% for HR-ALL and 14.9% for SR-ALL. A mould-active agent was used in 77.4% of AML cycles and 21.2% of HR-ALL cycles. Mould-active prophylaxis was associated with a lower risk of IFD overall and increased IFD-free survival in AML.
Interpretation
These data demonstrate the persistent high regional burden of IFD in children with HR-ALL, and the potential for mould-active prophylaxis to ameliorate this. Strategies to increase uptake of appropriate prophylaxis are required in this cohort.

Background
It is unclear how pre-surgery transfer relates to readmission destination among patients undergoing cardiac surgery and whether readmission to a hospital other than the operating hospital is associated with increased mortality.
Methods
We analysed linked hospital and death records for residents of New South Wales, Australia, aged ≥18 years who had an emergency readmission within 30 days following coronary artery bypass graft (CABG) or surgical aortic valve replacement (SAVR) in 2003–2022. Mixed-effect multi-level modelling was used to evaluate associations of readmission destination with 30-day mortality, overall and stratified by pre-surgery transfer.
Findings
Of 102,540 patients undergoing cardiac surgery (isolated CABG = 63,000, SAVR = 27,482, combined = 12,058), 28.7% (n = 29,398) had pre-surgery transfer, while the 30-day readmission rate was 14.7% (n = 14,708). During readmission, 35.7% (3499/9795) of those without pre-surgery transfer and 12.0% (590/4913) of those with pre-surgery transfer returned to the operating hospital. Among readmitted patients, 30-day mortality did not differ significantly for those who were readmitted to a non-index hospital, both overall (adjusted odds ratio [aOR] = 1.03 95% CI 0.75–1.41), and in analyses stratified by pre-surgery transfer (no transfer: aOR = 1.07, 95% CI 0.75–1.52; transfer: aOR = 0.88, 95% CI 0.45–1.72). Among patients who had pre-surgery transfer, 30-day mortality was similar among patients who were readmitted to the index operating hospital (reference), the initial admitting hospital (aOR = 1.00, 95% CI 0.50–2.00) or a third, different, hospital (aOR = 0.70, 95% CI 0.33–1.48).
Interpretation
Although many Australian patients who are readmitted following cardiac surgery are readmitted to hospitals different to the operating or initial admitting hospital, such readmissions are not associated with increased mortality.

背景目前还不清楚手术前转院与心脏手术患者再入院目的地之间的关系，也不清楚再入院到手术医院以外的医院是否与死亡率升高有关。方法我们分析了澳大利亚新南威尔士州居民的关联医院和死亡记录，这些居民年龄≥18岁，在2003-2022年期间接受冠状动脉旁路移植术（CABG）或主动脉瓣置换术（SAVR）后30天内急诊再入院。在接受心脏手术的 102,540 名患者中（孤立 CABG = 63,000 人，SAVR = 27,482 人，合并 = 12,058 人），28.7%（n = 29,398 人）在手术前转院，而 30 天内再入院率为 14.7%（n = 14,708 人）。在再入院期间，35.7%（3499/9795）没有手术前转院的患者和12.0%（590/4913）有手术前转院的患者返回了手术医院。在再次入院的患者中，再次入院到非指标医院的患者的 30 天死亡率没有显著差异，无论是总体上（调整后的几率比 [aOR] = 1.03 95% CI 0.75-1.41），还是按手术前转院进行的分层分析（未转院：aOR = 1.07，95% CI 0.75-1.52；转院：aOR = 0.88，95% CI 0.45-1.72）。在手术前转院的患者中，再次入住手术医院（参考）、最初入院医院（aOR = 1.00，95% CI 0.50-2.00）或第三家不同医院（aOR = 0.70，95% CI 0.33-1.48）的患者的 30 天死亡率相似。释义尽管许多澳大利亚患者在心脏手术后再次入院时，入院医院与手术医院或最初入院医院不同，但这种再次入院与死亡率增加无关。

Background
Fiji has among the highest global reported prevalence of scabies. Mass drug administration (MDA) has been identified as a potentially effective strategy to control scabies, but acceptability of MDA from the perspectives of people receiving and delivering scabies MDA programs remains underexplored in Fiji and globally.
Methods
A qualitative study was conducted after completion of the national MDA campaign. Participants included 44 community members and 12 key informants across the Central and Western Divisions of Fiji. Semi-structured face-to-face and virtual interviews were conducted in August and September 2023. An interpretive research approach was adopted, and data were analysed using deductive and inductive techniques.
Findings
We identified several barriers and facilitators to scabies MDA acceptability. Facilitators included prior experiences of scabies and knowledge of the potential health benefit of MDA, community attitudes to MDA and neighbours’ adherence practices, endorsement of MDA by community leaders, community consultation and exposure to community sensitisation, and involvement of local key informants during planning and implementation. Barriers included a lack of trust in MDA campaigns, religious beliefs, limited reach of community sensitisation, and challenges to implementing MDA in urban locations.
Interpretation
This is the first qualitative study documenting acceptability of a nationwide scabies-MDA globally. It identified diverse socio-structural factors that influenced MDA implementation and acceptability. Future MDA programs could benefit from widespread community sensitisation, tailored approaches to urban and rural MDA design and delivery, and the inclusion of communities in the co-design and implementation of MDA programs.

Background
A comprehensive profile of cardiovascular disease (CVD) burden and human resources for health (HRH) distribution in the WHO Western Pacific region has yet to be presented. Studies on the relationship between HRH and CVD in this region are limited. We aimed to describe CVD trends and HRH density in the Western Pacific region and explore the association of HRH with CVD burden.
Methods
Estimates of CVD deaths and disability-adjusted life years (DALYs) were obtained from the Global Burden of Disease Study (GBD) 2021, and the annual density of HRH was retrieved from GBD 2019. We presented trends in CVD burden and HRH density across 31 Western Pacific countries. Spearman rank correlation analysis and generalized linear models were used to examine associations between CVD burden and HRH density.
Findings
In 2021, CVD caused six million deaths and 125 million DALYs in the Western Pacific region, accounting for 39.4% and 22.5% of all-cause deaths and DALYs. From 1990 to 2021, the number of CVD deaths and DALYs increased by 94.9% and 57.3% in this region, whereas the age-standardized rate of CVD deaths and DALYs declined in all countries. In 2021, stroke and ischemic heart disease were the leading causes in the Western Pacific region, and a 32-year increase in CVD burden was primarily driven by aortic aneurysm, lower extremity peripheral arterial disease, endocarditis, and atrial fibrillation and flutter. In 2019, there was an approximately 20-fold difference in HRH density across 31 countries from the lowest in Papua New Guinea to the highest in Australia. HRH density was negatively related to the age-standardized rate of CVD deaths (rs = −0.74) and DALYs (rs = −0.73), especially strong associations between CVD burden and the density of dentistry personnel, aides & emergency medical workers, and medical laboratory technicians.
Interpretation
CVD remains a pressing public health issue in the Western Pacific region where noticeable shortages in health workers exist. The negative associations between CVD burden and HRH density suggest that health workers, especially dentistry personnel, aides & emergency medical staff, and medical laboratory technicians merit more investment to reduce the CVD burden.

In the Western Pacific Region, the prevalence of dementia is expected to increase, however, the diversity of the region is expected to present unique challenges. The region has varying levels of preparedness, with a limited number of countries having a specific national dementia plan and awareness campaigns. Diversity of risk and healthcare services within the region is exerting impact on diagnosis, treatment, care, and support, with most countries being under resourced. Similarly, the ability to monitor dementia-related indicators and progress research, particularly relating to treatment and clinical trial access needs to be addressed. Countries require comprehensive national plans that lay out how resources will be allocated to improve dementia literacy, train, and support carers, mobilise resources to reduce risk factors and improve research capabilities. These plans need to be informed by consumers and tailored to the region to develop an inclusive society for people living with dementia and their families.

The Western Pacific region is home to approximately 25% of the world's population. In the absence of cures for dementia, it is essential to focus on appropriate and accessible care pathways for people living with dementia and their families. This approach will ultimately result in timely diagnosis and improved care and support.
Ensuring adequate dementia care and support pathways has been a longstanding issue in many developed countries and is becoming a more prominent issue in countries with rising dementia prevalence rates but comparatively limited health resources.
This Viewpoint provides an overview of system-level post-diagnosis dementia care, from diagnosis to rehabilitation, across some of the region's lower (Laos, Solomon Islands, Philippines) and upper (China) middle income and high income (South Korea, Australia) countries. Gaps and challenges in post-diagnosis dementia care, as well as suggestions for optimal care, are discussed. This Viewpoint highlights highly variable system level post-diagnosis dementia care in the region.

Background
Guidelines recommend routine blood pressure measurement at health facilities. We estimated the potential for opportunistic screening for hypertension at health facilities to change the level and distribution of diagnosed hypertension in the older population of the Philippines.
Methods
We used a representative, nationwide sample of Filipinos aged 60 years and older and classified respondents as a) hypertensive if they had high (≥140/90 mm Hg) blood pressure (BP) or were taking BP medication, b) diagnosed if told have high BP by a doctor, and c) a missed opportunity for diagnosis if they were hypertensive, undiagnosed and had an outpatient visit to a health facility in the past 12 months. We assumed c) would be diagnosed if health facilities operated opportunistic screening. We estimated percentages of hypertensives diagnosed and with a missed opportunity overall, by wealth quintile and covariates, with age-sex and, then, full adjustment.
Findings
We estimated that opportunistic screening at health facilities would increase the percentage of hypertensives diagnosed from 62.7% (95% CI: 58.2, 67.0) to 74.4% (95% CI: 70.9, 77.6). The increase would be larger in richer groups due to lower (private) healthcare utilization by poorer, undiagnosed hypertensives.
Interpretation
Opportunistic screening for hypertension, if effectively implemented at health facilities, would substantially increase diagnosis but exacerbate inequality unless barriers discouraging poorer, older Filipinos from accessing outpatient and primary care were lowered.
