Article Abstract

Social epidemiological studies have shown for decades that wealth shows associations to various health outcomes in addition to more frequently used and established indicators like income, education and occupational status. Measurements of income alone are not able to assess the economic position and resources of individuals, while they neglect transgenerational and cumulative pathways of shaping socioeconomic status (SES) and their impact on health. Despite this established knowledge, the use of measurements of wealth in epidemiological studies is very rare and heterogeneous.Therefore, a number of open questions still need to be answered: How does wealth relate to other socioeconomic and sociodemographic indicators with associations to health? On which pathways is wealth influencing individuals' health? What role does wealth play as a driver for health disparities across populations? Moreover, how does wealth interact with age, gender and race?To further research on these questions, we use this essay to elaborate on the term wealth and its role in social epidemiological research, review results from observational studies, discuss inconsistent results and conclude why it is important to consider wealth as a dimension of SES. In addition, we present a conceptual idea for integrating wealth in a life course-based concept of SES and show what information an assessment of wealth could provide in addition to other established SES indicators.

Background: Tobacco use remains a major public health challenge in sub-Saharan Africa, with significant gendered dimensions. Place of residence is an important determinant, as rural and urban contexts shape exposure, access, and consumption patterns. This study investigates rural-urban disparities in tobacco use among women in sub-Saharan Africa, with a focus on quantifying the relative contributions of socioeconomic factors.

Timely access to comprehensive , high-quality emergency obstetric and neonatal care can prevent maternal and neonatal mortality but remains challenging in Benin. We examine geographic accessibility to childbirth care (CBC) in Grand Nokoué, the largest conurbation in Benin. We gathered data on boundaries, health facilities, road network, elevation, land cover, relative wealth, urbanicity, and geo-traced travel speeds over 45 days during the rainy season.

Objectives: There is a wealth of reviews investigating the relations between healthcare worker (HCW) variables and quality of care (QoC) outcomes. Individually, these reviews predominantly focus on one aspect relevant to HCWs' functioning at work, unintentionally contributing to a scattered body of evidence. This umbrella review uses the concept of sustainable employability (SE)-a multidimensional construct that captures an individual's long-term ability to function adequately at work and in the labour market-to integrate existing reviews on the topic, and to examine if and how HCWs' SE is related to QoC.

KMT2A-rearranged leukemia: from mechanism to drug development.

Exp Hematol

September 2025

Tsuruoka Metabolomics Laboratory, National Cancer Center, Tsuruoka, Yamagata 997-0052, Japan. Electronic address:

Gene rearrangements of the human MLL gene (also known as KMT2A) generate multiple fusion oncoproteins which cause leukemia with poor prognosis. MLL is an epigenetic regulator that reads and writes epigenetic information and has an evolutionarily conserved role maintaining expression of Homeotic (HOX) genes during embryonic development. Most MLL gene rearrangements found in leukemia generate a constitutively active version of the wild-type protein, which causes overexpression of HOX and other genes and leukemic transformation of normal hematopoietic progenitors.

Introduction: Access to water, sanitation, and hygiene (WASH) is critical for public health but remains inadequate in marginalized areas, particularly in sub-Saharan Africa's artisanal and small-scale mining (ASM) communities. Adolescent girls and young women (AGYW) in these settings face unique challenges that impact their health and wellbeing.

Objective: This study aimed to assess WASH access among adolescent girls and young women (aged 10-24) in last-mile ASM communities in Ghana and Uganda, identifying disparities and factors influencing access.
