气候变化和抗菌素耐药性(AMR)正在加剧全球公共卫生威胁。西太平洋地区面临着独特的气候和社会经济脆弱性,但关于这种气候-抗菌素耐药性交叉的证据有限。我们的目标是系统地提供有关这一关键问题的证据。方法采用三阶段混合方法进行系统分析:(1)通过叙述性综述,绘制区域抗菌素耐药性格局,总结潜在的气候驱动机制;(2)区域定量研究的系统综述(PubMed and谷歌Scholar, 2000年1月- 2025年3月);(3)利用纵向面板数据进行实证定量分析。该分析通过可视化AMR死亡率趋势(使用来自GRAM项目的数据)和应用回归分析对基于气候和社会经济因素的AMR归因死亡率进行建模,从而完成了我们的系统方法,为区域情况及其潜在驱动因素提供了定量证据。研究结果文献综述证据表明,气候变化引起的温度升高直接加速了细菌生长和耐药性突变率,并间接影响极端天气事件期间医疗保健中断和抗生素滥用。我们纳入了使用SWiM框架合成的18项定量研究,这些研究提供了更具体的证据,表明较高的温度与临床耐药率增加和抗生素耐药基因(ARGs)的环境传播增强有关。我们的定量分析发现,平均环境温度升高1°C与耐碳青霉烯鲍曼不动杆菌(CRAB; β = 0.652, 95% CI 0.579-0.724, p < 0.001)和耐碳青霉烯铜绿假单胞菌(CRPA; β = 0.422, 95% CI 0.304-0.541, p < 0.001)的amr导致的死亡率升高相关。研究还表明,社会经济因素具有异质性影响。气候条件和社会经济脆弱性共同影响了西太平洋地区的抗菌素耐药性风险。预计极端天气事件的增加可能会进一步给卫生保健系统带来压力,并加剧抗生素滥用。加强适应气候变化的卫生系统、改善多部门抗菌素耐药性治理以及建立抗菌素耐药性气候综合监测网络是本区域的重要优先事项。世界卫生组织(WPRO/2024-02/年龄- dhp / 225524)、国家自然科学基金项目(82422064,82250610230,72374228,72074234)、北京市自然科学基金项目(IS23105)、国家疾病预防控制局项目(20241660047)、广州市基础与应用基础研究计划项目(2025A04J5118)、中央高校基本科研业务费项目(SYSU-25wkjc02)资助。中国国家科技重大专项(No. 2024ZD0524500)和新加坡国家医学研究理事会(CoSTAR-HS CG21APR2005; AMRITS MOH-001326-01)。

Ethical research governance across Pacific island countries and areas (PICs) faces challenges from limited local capacity and disproportionate external influences. However, a shared commitment to advance and strengthen ethical oversight is increasingly emerging. In May 2025, WHO, the Pacific Community, and the Pacific Academy of Sciences convened a workshop with PIC representatives to review existing health research ethics ecosystems and define priorities for improvement. Mapping efforts revealed wide disparities: some countries have formal legal frameworks and established ethics committees, while others rely on informal processes or external approvals. Concerns were expressed about externally driven research, limited local control, inconsistent consent practices, and weak mechanisms to ensure communities benefit from research. Key priorities included developing national policies that clarify governance roles and standards, creating Pacific-wide ethical research guidelines that reflect regional values, and embedding long-term capacity building and fair benefit-sharing into research partnerships. The workshop highlighted that ethical research governance is not only a technical necessity but also central to self-determination, cultural integrity, and equity. Moving forward, progress will require sustained investment, regional collaboration, and global partners to support research led by the Pacific, for the benefit of Pacific communities.

Antimicrobial resistance poses a significant threat to children's health, with up to 20% of 1.27 million deaths attributable to bacterial AMR annually, occurring in children <5 years. The WHO 2024 Bacterial Priority Pathogens List identifies methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecium (VRE) as critical pathogens. This review examines the epidemiology, treatment recommendations, dosing strategies, efficacy, and safety data for antibiotics targeting MRSA and VRE infections in children in Oceania. Paediatric MRSA infections are prevalent (13–43%) across Oceania, while VRE infections remain uncommon (3–5%). Disparate access to recommended treatments, particularly in Pacific Island Countries and Territories, highlights the need for paediatric licensing. Paediatric trials primarily assess safety, with efficacy data limited to vancomycin, teicoplanin, and daptomycin. Pharmacokinetic/pharmacodynamic studies show standard dosing in children under 12 years often fails to achieve therapeutic targets, highlighting the need for dedicated dosing studies. Addressing these gaps is essential to advancing paediatric access to optimal treatment for drug-resistant infections in the region.

The growing diabetes burden in Indonesia necessitates a comprehensive understanding of national diabetes care performance, which remains inadequately characterized. Evaluating care quality across domains is essential to inform chronic disease policy and improve health outcomes. This study assesses trends in behavioral, clinical, and laboratory outcomes of diabetes care in Indonesia from 2013 to 2023.
Methods
We conducted a serial cross-sectional analysis of pooled data from the 2013, 2018, and 2023 Indonesian national health surveys (N = 42,224 for behavioral-clinical and N = 2957 for laboratory outcomes). Diabetes care performance was assessed across behavioral (treatment, smoking, diet, activity), clinical (blood pressure, BMI, waist length), and laboratory (glucose, lipids, renal function) domains. Composite scores and multilevel models were used to identify geographic and sociodemographic disparities.
Findings
Although linkage to diabetes care significantly improved from 68% to 92% between 2013 and 2023, performance in most other indicators remained stagnant or declined. In 2023, only 2.9% (95% CI 2.5–3.3%) met dietary fiber intake targets, 62.4% (95% CI 61.2–63.6%) achieved physical activity goals, and 83.9% (95% CI 82.9–84.8%) abstained from smoking. Clinical control was suboptimal, with 43.5% (95% CI 42.3–44.8%) meeting blood pressure targets and only 26.7% (95% CI 25.6–27.9%) and 33.1% (95% CI 32.0–34.3%) achieving BMI and waist circumference goals, respectively. Laboratory control was limited: only 25.2% (21.6–28.8%) achieved fasting glucose targets, 32.0% (95% CI 27.6–36.3%) had HbA1c <7%, and only 22.6% (95% CI 19.1–26.2%) met LDL-C goals. Fewer than 5% of participants met all behavioral-clinical or laboratory composite targets. Composite performance declined in nearly all provinces, with disparities linked to older age, male sex, lower education, and rural residence.
Interpretation
Despite expanded healthcare coverage, Indonesia's diabetes care performance remains critically inadequate, particularly for achieving multiple targets. Strengthening national guidelines, embedding structured chronic care, and addressing social determinants are essential to improving diabetes outcomes.

印度尼西亚日益增长的糖尿病负担需要对国家糖尿病护理绩效进行全面了解,但仍未充分表征。评估跨领域的护理质量对于为慢性病政策提供信息和改善健康结果至关重要。本研究评估了2013年至2023年印度尼西亚糖尿病护理的行为、临床和实验室结果趋势。方法:我们对2013年、2018年和2023年印度尼西亚国家健康调查的汇总数据进行了连续横断面分析(N = 42,224例行为-临床调查,N = 2957例实验室调查)。通过行为(治疗、吸烟、饮食、活动)、临床(血压、BMI、腰围)和实验室(葡萄糖、脂质、肾功能)对糖尿病护理表现进行评估。综合得分和多层次模型被用于识别地理和社会人口差异。研究发现,尽管在2013年至2023年期间,与糖尿病护理的联系从68%显著提高到92%,但大多数其他指标的表现仍然停滞不前或有所下降。2023年,只有2.9% (95% CI 2.5-3.3%)的人达到了膳食纤维摄入目标,62.4% (95% CI 61.2-63.6%)的人达到了体育锻炼目标,83.9% (95% CI 82.9-84.8%)的人戒烟。临床控制是次优的,43.5% (95% CI 42.3-44.8%)达到血压目标,分别只有26.7% (95% CI 25.6-27.9%)和33.1% (95% CI 32.0-34.3%)达到BMI和腰围目标。实验室控制是有限的:只有25.2%(21.6-28.8%)达到空腹血糖目标,32.0% (95% CI 27.6-36.3%)的HbA1c和lt达到7%,只有22.6% (95% CI 19.1-26.2%)达到LDL-C目标。不到5%的参与者符合所有行为-临床或实验室复合目标。几乎所有省份的综合表现都有所下降,差异与年龄较大、男性、受教育程度较低和农村居住有关。尽管扩大了医疗保健覆盖范围,但印度尼西亚的糖尿病护理表现仍然严重不足,特别是在实现多个目标方面。加强国家指南、纳入有组织的慢性护理和解决社会决定因素对于改善糖尿病结局至关重要。

Background
Acute rheumatic fever is an immune-mediated condition triggered by Streptococcus pyogenes sore throat and possibly skin infection, with a substantial burden in resource-limited settings. Clinical decision rules (CDRs) are commonly used to guide antibiotic treatment of sore throat based on signs and symptoms, but their diagnostic accuracy varies by study and setting. This work aimed to assess the accuracy of multiple CDRs in Fiji to diagnose S. pyogenes sore throat.
Methods
We conducted a prospective diagnostic accuracy study at two primary healthcare centres in Suva, Fiji, enrolling children aged 5–15 years presenting with sore throat. Clinical features were assessed, and two throat swabs were collected from each participant for S. pyogenes detection using culture and a point-of-care nucleic acid amplification test (NAAT). Six CDRs were evaluated against NAAT and culture as reference standards.
Findings
Of 250 participants, S. pyogenes was detected among 31.7% (95% CI: 26.0–37.9) by NAAT and 10.4% (95% CI: 7.6–15.8) by culture. The Fiji CDR demonstrated high sensitivity (98.7%, 95% CI: 93.1–100 vs. NAAT; 100%, 95% CI: 86.8–100 vs. culture) but very low specificity (4.7% (95% CI: 2.1–9.1) vs. NAAT; 4.0% (95% CI: 1.9–7.5) vs. culture). All CDRs had poor discriminatory power (area under receiver operating characteristic curve: 0.48–0.55).
Interpretation
CDRs cannot accurately diagnose S. pyogenes sore throat in this tropical setting where rheumatic fever is common. There appears to be a high burden of S. pyogenes sore throat in Fiji, apparently underestimated when traditional culture-based methods are used. Although NAAT testing offers higher sensitivity than culture, the costs remain high. There is an urgent need for accurate, affordable diagnostics to guide sore throat management in resource-limited settings.

Real-world evidence on decentralised, primary-care delivery for hepatitis C virus (HCV) in the Western Pacific is limited. We evaluated Cambodia's national, primary care–led HCV programme in 2024.
Methods
We analysed facility-level data from 256 health facilities in 15 operational districts to assess six HCV cascade steps: screening, anti-HCV positivity, RNA testing, viraemia, treatment initiation, and treatment completion. Design-based survey estimators were used to estimate proportions with 95% confidence intervals (CIs). To account for multi-stage design (clustering within operational districts), design-based generalised linear models were utilised to assess the factors associated with viraemia, treatment initiation and completion.
Findings
HCV testing coverage among adults (≥18 years; denominator 2,196,351) was 3·5% (95% CI 2·5–4·4). Of 76,512 adults tested, 3213 (4·2%; 95% CI 3·1–5·6) were anti-HCV-positive; 2628/3213 (81·8%) received RNA testing, and 1446/2628 (55·0%; 95% CI 49·5–60·3) were viraemic (1·9% of all tested). Among RNA-positive individuals, 1345/1446 (93·0%) initiated direct-acting antivirals and 1289/1345 (95·8%) completed treatment. Viraemia was higher among men (adjusted odds ratio [aOR] 1·40; 95% CI 1·05–1·86), varied by province (Takeo aOR 2·79, Kampong Cham aOR 2·11 versus Battambang), and elevated in October–December (Q4; aOR 1·79) versus January–March. Treatment initiation and completion surpassed 90% across facilities. The principal gap was confirmatory testing (18·2% of anti-HCV-positive individuals lacked RNA testing).
Interpretation
A decentralised, primary-care model achieved high linkage and treatment completion in the first year. Closing the confirmatory testing gap (reflex RNA/core antigen from same encounter), prioritising low-coverage/high-burden districts, and establishing patient-level linkage to capture sustained virologic response at week 12 are priorities to accelerate elimination.

现实世界中关于西太平洋地区丙型肝炎病毒(HCV)分散初级保健服务的证据有限。我们评估了柬埔寨2024年以初级保健为主导的国家HCV规划。方法我们分析了来自15个业务区256个卫生机构的设施级数据,以评估6个HCV级联步骤:筛查、抗HCV阳性、RNA检测、病毒血症、开始治疗和完成治疗。使用基于设计的调查估计器以95%置信区间(ci)估计比例。为了考虑多阶段设计(在操作区域内聚集),采用基于设计的广义线性模型来评估与病毒血症、治疗开始和完成相关的因素。发现成人(≥18岁;分母2,196,351)的shcv检测覆盖率为3.5% (95% CI 2.5 - 4.4)。在接受检测的76,512名成人中,3213名(4.2%;95% CI 3.1 - 5.6)为抗hcv阳性;2628/3213例(81.8%)接受了RNA检测,1446/2628例(55.0%;95% CI 49.5 - 60.03)为病毒血症(占所有检测的1.9%)。在rna阳性个体中,1345/1446(93.0%)开始使用直接抗病毒药物,1289/1345(95.8%)完成治疗。男性病毒血症较高(校正优势比[aOR] 1.40; 95% CI 1.05 - 1.86),因省而异(武夫比值为2.79,磅湛比值为2.11,马德望比值为2.11),10 - 12月(Q4; aOR为1.79)高于1 - 3月。所有设施的治疗启动和完成率超过90%。主要的差距是确认性检测(18.2%的抗hcv阳性个体缺乏RNA检测)。解释:一种分散的初级保健模式在第一年实现了高度的联系和治疗完成。消除确认性检测差距(来自相同遭遇的反射RNA/核心抗原),优先考虑低覆盖率/高负担地区,并建立患者层面的联系,以在第12周捕获持续的病毒学反应,是加速消除的优先事项。基金编号:anrs MIE (ANRS0689b)。

Background
Socio-economic inequality and vaccination inequity have long been critical issues. However, no studies have explored the gap in influenza vaccination uptake between public and private schools. Importantly, the extent to which socio-economic inequality translates into vaccination uptake inequity has not been quantified. We investigate influenza vaccination uptake among school-aged Australian children in 2023, compare uptake between public and private schools, and assess the role of socio-economic inequality in vaccination uptake inequity.
Methods
We analysed whole-of-population linked immunisation, census, and administrative data. Multivariable logistic regression was used to identify key uptake predictors, and the Oaxaca-Blinder decomposition was used to identify factors driving uptake inequity between public and private schools.
Findings
Of 9.5 million influenza vaccination doses administered, only 0.7 million (7%) were given to school-aged children (5–<18 years), who represent 16% of the population. Coverage among school-aged children was low. Secondary school-aged children had the lowest uptake, with a significant gap between public and private schools. Children in private secondary schools, who demonstrate greater socio-economic advantage, had higher uptake than their public peers (unadjusted OR = 1.47; 95% CI: 1.45–1.57). Two-thirds of the uptake gap is driven by differences in cultural, linguistic, and socio-economic characteristics, with parental education, parental income, and socio-economic characteristics of residential area being the strongest contributors.
Interpretation
Addressing socio-economic inequality among parents could reduce vaccination uptake inequity for children. Future influenza vaccination campaigns should consider tailored strategies for specific cultural, linguistic, and socio-economic groups.
