Metabolomic epidemiology offers insights into disease aetiology.

Metabolomic epidemiology is the high-throughput study of the relationship between metabolites and health-related traits. This emerging and rapidly growing field has improved our understanding of disease aetiology and contributed to advances in precision medicine. As the field continues to develop, metabolomic epidemiology could lead to the discovery of diagnostic biomarkers predictive of disease risk, aiding in earlier disease detection and better prognosis. In this Review, we discuss key advances facilitated by the field of metabolomic epidemiology for a range of conditions, including cardiometabolic diseases, cancer, Alzheimer's disease and COVID-19, with a focus on potential clinical utility. Core principles in metabolomic epidemiology, including study design, causal inference methods and multi-omic integration, are briefly discussed. Future directions required for clinical translation of metabolomic epidemiology findings are summarized, emphasizing public health implications. Further work is needed to establish which metabolites reproducibly improve clinical risk prediction in diverse populations and are causally related to disease progression.

Project UPLIFT: Adoption and implementation experiences of an epilepsy self-management program.

RATIONALE: Project UPLIFT is an evidence-based epilepsy self-management program shown to prevent and treat depression through an 8-session, group telehealth intervention. Since 2012, the program has been disseminated by training community-based providers to deliver UPLIFT to people with epilepsy (PWE). Limited research has described the adoption, implementation, and practice-based maintenance of self-management programs like UPLIFT. We sought to gain a better understanding of this process from trained program adopters. METHODS: A cross-sectional evaluation of adoption and implementation experiences was conducted. An online survey with closed- and open-ended questions was distributed to 120 UPLIFT program adopters to collect information about reasons for being trained and experiences implementing the program. Survey items were developed based on the RE-AIM model to assess program reach, effectiveness, adoption, implementation, and maintenance. For closed-ended responses, frequencies and cross-tabs were calculated. Open-ended responses were reviewed and grouped by theme. RESULTS: 41 respondents completed the survey (34% response rate). Respondents were from a variety of organizations including clinical (39%, n = 16), educational/research (17%, n = 7), and Epilepsy Foundation affiliates/chapters (12%, n = 5), among others. The most frequently endorsed reason for training in UPLIFT was an interest in supporting PWE (73%, n = 30). Most respondents rated delivering UPLIFT as very important (49%, n = 20) or important (32%, n = 13) to the organization. Sixty-one percent (n = 25) of respondents reported implementing (implementors) UPLIFT. Of those who had not yet implemented UPLIFT, 50% (n = 8) planned on implementing it at some point. Among program implementors, the most frequently reported implementation facilitators included participant interest (68%, n = 17), training (68%, n = 17), and organizational support (64%, n = 16). Program implementors indicated having program champions (80%, n = 20). The most frequently reported implementation challenge reported was recruitment (72%, n = 18). In open-ended responses, funding was a key theme that would facilitate continued implementation, but 48% (n = 12) responded that did not have access to resources and/or funding to help continue offering UPLIFT. Developing partnerships was recommended to improve the reach and maintenance of the program. Despite challenges, implementors agreed (44%, n = 11) or strongly agreed (36%, n = 9) that UPLIFT was effective in addressing mental health problems among program participants, and 76% (n = 19) plan on continuing to offer UPLIFT. CONCLUSION: Implementation surveys increase understanding of program adoption and impact for dissemination trainees. Implementation benefits from program champions, strong partnerships, and sustained funding. Continued refinement of implementation support, such as developing a sustained referral system, maintaining relationships with trainees, supporting evaluation activities, and exploring opportunities for program updates to further enhance adoption, implementation, and maintenance.
