These include nutrition, air pollution, social deprivation, lifestyle factors, climate change and exposure to environmental toxins, including microplastics and nanoplastics. The development of the concept of the exposome of ageing and the emergence of the new field of 'exposomics' have identified a blind spot, in particular, for geroscience. The impact of the exposome affecting human 'healthspan' (i.e., years lived in good health), extending across generations, is significant and yet under-explored in research. As such, it is under-appreciated that the declining health of the planet will have intergenerational ripple effects, epigenetically priming adverse health in future generations. We discuss the capacity to manipulate our exposome to mitigate against such effects, by addressing root causes, rather than symptoms, of both physiological and planetary dysregulation, dysfunction and decay. We propose a systems-based framework that reconnects research on ageing with exposomics and planetary ecology, creating a new field of 'ecological or exposome pharmacology', harnessing the activity of Nrf2 as a senotherapeutic intervention to improve trans- and intergenerational physiology in the face of declining planetary health.</p>","PeriodicalId":196,"journal":{"name":"Journal of Internal Medicine","volume":" ","pages":""},"PeriodicalIF":9.2,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145342327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show, with data from Sweden, that the interpretation of how mortality inequalities evolve over the life course is markedly different depending on whether we focus on absolute or relative inequalities. Although there is a consensus on basic descriptive facts, disagreements on how these facts are best explained and why they persist and even increase remain. We present a general discussion on how to explain health inequalities, as well as a discussion on why patterns may differ between European regions and across the life course.

We review contemporary discussions on health inequalities in light of recent evidence based on novel methods for causal inference.

TGA values 7.0-14.0 U/mL were defined as low positive and 3.0-6.9 U/mL as borderline negative.

Among those with low positive TGA, all EmA positive and 50% of the EmA negative subjects were diagnosed with CeD. Thirty-nine individuals (13%) had borderline negative TGA, and 36% were positive for EmA. Of these, 79% of EmA positive and 12% of EmA negative subjects were diagnosed with CeD. Additionally, 29% of the subjects with borderline negative TGA and no diagnosis exhibited signs of incipient CeD, including positive IgA deposits, increased density of γδ+ IELs and presence of human leukocyte antigen DQ2/DQ8. All subjects with TGA ≥ 3.2× upper limit of normal (22.4 U/mL) received a CeD diagnosis.</p><p><strong>Conclusion: </strong>Low positive and borderline negative TGA frequently implies a CeD diagnosis, particularly in EmA positive individuals, or at least may be an indicator of an early stage of the disease.</p>","PeriodicalId":196,"journal":{"name":"Journal of Internal Medicine","volume":" ","pages":""},"PeriodicalIF":9.2,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145136019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
