Spatially Organized Immune Remodeling in Menopause: Single-Cell and Spatial Transcriptomic Evidence from Ovarian Aging and Atherosclerosis

Yinshu Zhang

As the proportion of people in their mid-to-late years increases around the world, so too does the prevalence of multiple long-term illnesses associated with menopause, many of which involve changes in the immune system. Bulk RNA sequencing averages expression in heterogeneous cell populations and thus cannot identify which cells are changing or where those changes occur. Collectively, single-cell RNA sequencing and spatial transcriptomics have provided two major examples of menopausal changes, ovarian aging and at …

High mpox mortality in people living with HIV and immune suppression: Lessons from Sierra Leone for integrated outbreak preparedness and response

Rosamund Felicity Lewis, Chikwe Andreas Ihekweazu

The 2025 mpox outbreak in Sierra Leone provides compelling evidence that people living with advanced HIV infection remain at greatly increased risk of death from mpox. The national cohort study by Ikoona et al demonstrates the value of integrated health information systems, linking 90% of confirmed mpox cases with their HIV status, largely using a national unique health identifier. The study illustrates how health service data can be used during an outbreak to identify vulnerable populations and guide interventions …

A scoping review on the economic burden of falls among older adults

Dhika Dharmansyah, Laili Rahayuwati, Iqbal Pramukti, Kuswandewi Mutyara

Abstract Background Falls are the second leading cause of unintentional injury death globally, and the World Health Organization estimates that approximately 82% of fall-related mortality occurs in low- and middle-income countries (LMICs). Despite this disproportionate burden, the economic impact of falls among older adults in resource-limited settings remains poorly documented. This scoping review aimed to map the existing evidence on the economic burden of falls among older adults, describe the extent and nature …

Long Noncoding RNAs in Aortic Dissection: Mechanistic Roles and Therapeutic Potential

Chao Chang, Yongrong Lan, Zhenhua Wu, Jie Geng, Zhigang Guo, Qingliang Chen

ABSTRACT Aortic dissection (AD) is a life‐threatening vascular disorder characterized by separation of the layers of the aortic wall, primarily triggered by an intimal tear or an intramural hemorrhage. Age is a well‐recognized and critical risk factor for AD. Epidemiological evidence consistently demonstrates a strong positive correlation between age and AD incidence, with peak occurrence in the 50–70‐year age group. Its pathogenesis involves vascular inflammation, extracellular matrix (ECM) degradation, vascular s …

Invisible harm and constrained response: a conceptual analysis of psychological domestic abuse against disabled people in China

Zehua Feng, Yilin Li, Wenzong Xia, Yu Hu

Psychological domestic abuse against disabled people is under-recognised at the intersection of violence prevention, public mental health, and disability policy. Here, invisible harm does not mean wholly unseen harm; it denotes cumulative abuse that remains difficult for victims, social networks, and institutions to identify or translate into action. Constrained response denotes the linked restrictions on recognition and disclosure, evidentiary translation, and safe exit. This conceptual analysis synthesises Chines …

Beyond anomie: The social and political consciousness of marginalized people

Christopher Wimmer

The political capacity of marginalized people to act has long been a recurring topic in political and public discourse. While a substantial body of scholarship has documented everyday forms of resistance, informal solidarity, and collective organization among marginalized groups, public debates and parts of the academic literature continue to portray them as politically disengaged, or incapable of collective action. This article contributes to that debate by examining how marginalized people themselves understand t …

Quality of Outcome Reporting for Older Subgroups in FDA Registration Gastroesophageal Cancer Trials (2010–2024): A Systematic Review

Ilse Trip, Martha Kormi, Elizabeth Smyth, Russell D. Petty, Mark A. Baxter

Background: Gastroesophageal adenocarcinoma is predominantly a disease of older adults. However, older adults are underrepresented in randomised controlled trials (RCTs), and outcomes specific to this subgroup are underreported. Clinicians therefore extrapolate data from younger, fitter trial populations, which can lead to over- and undertreatment of older cancer patients. This study examines the inclusion and completeness of outcome reporting for older patients in practice-changing trials in gastroesophageal cance …

Ferroptotic stress promotes hematopoietic stem cell aging through S1P-dependent epigenetic and lipid remodeling

Yijun Zhao, Yishan Li, Xiaobin Tian, Jingjing Guan, Yixin Ma, Xiaoqi Wang, Hongjian Zhang, Kaitao Wang, Kaizheng Jiang, Yalan Yang, Yuan Pan, Weiwei Liu, Xianzhe Hu, Jiafan Cao, Weiming Liu, Mengyun Xie, Kexin Sun, Jiayin Zheng, Ying Wang, Yucan Zheng, Yanjun Ling, Keyue Yang, Xuying Pei, Xiang-yu Zhao, Xi Zhang, Pengxu Qian, Changzheng Li, Tian Lan, Linjia Jiang, Meng Zhao

Aging of hematopoietic stem cells (HSCs) impairs hematopoietic regeneration and differentiation, contributing to immune aging, systemic inflammation, and reduced lifespan. Strategies to rejuvenate aged HSCs and restore immune homeostasis remain limited. Here, we identify ferroptotic stress as a key contributor to HSC aging. Mechanistically, increased sphingosine metabolism elevates sphingosine-1-phosphate (S1P), which suppresses HDAC activity and enhances H3K9 acetylation to upregulate lysophosphatidylcholine acylt …
