Article Abstract

DNA methylation plays a crucial role in human diseases pathogenesis. Substantial experimental evidence from clinical and biological studies has confirmed numerous methylation-disease associations, which provide valuable prior knowledge for advancing precision medicine through biomarker discovery and disease subtyping. To systematically mine reliable methylation prior knowledge from known DNA methylation-disease associations and develop robust computational methods for precision medicine applications, we propose MethPriorGCN. By integrating layer attention mechanisms and feature weighting mechanisms, MethPriorGCN not only identified reliable methylation digital biomarkers but also achieved superior disease subtype classification accuracy.

Background: Mental health problems are common in the working-age population. More knowledge is needed on how to support work participation and reduce sickness absence. The objective of the study was to estimate the distribution of mental well-being and work capacity in women and men in a working population and assess the association between mental well-being and work capacity, while adjusting for sociodemographic characteristics, health status, and working positions.

Background: As populations age, more knowledge is needed on people who extend their working lives. The aim of this study was to explore if prior sickness absence (> 14 days) and/or disability pension (SADP) in mental and/or somatic diagnoses were associated with time until work exit after ages 65-69 and ≥ 70, respectively, among women and men.

Methods: This prospective population-based cohort study included all 65-69-year-olds (cohort65, n = 201,263) and ≥ 70-year-olds (cohort70, n = 93,751) who were in paid work in Sweden in 2014.

The body of knowledge on trauma is rapidly expanding. Since 2022, the WHO has been calling for the history of adversity to be systematically taken into account when assessing the state of health of all individuals. But at this stage, our understanding of the precise mechanisms of complex trauma remains incomplete.

Background: More than 20% of cervical cancers are diagnosed in women older than 65 years. Guidelines recommend screening exit at age 65 for average-risk patients only if certain criteria are met, yet most women aged 64-66 years in the United States are inadequately screened. In this mixed methods study, we explored clinician knowledge of exit criteria.

Background: Cancer screening nonadherence persists among adults who are deaf, deafblind, and hard of hearing (DDBHH). These barriers span individual, clinician, and health care system levels, contributing to difficulties understanding cancer information, accessing screening services, and following treatment directives. Critical communication barriers include ineffective patient-physician communication, limited access to American Sign Language (ASL) cancer information, misconceptions about medical procedures, insurance navigation difficulties, and intersectional barriers for multiply marginalized individuals.
