A healthy diet improves glycaemic control and reduces cardiovascular risk in type 2 diabetes (T2D). However, access to dietitians is limited. Several countries have implemented mandatory interpretive front-of-pack labelling to guide consumers towards healthier food choices, but Sweden has not. Smartphone applications may offer an alternative platform to provide such information. This study evaluates the dietary and clinical impact of a novel application providing interpretive labelling to Swedish adults with T2D.

This is a fully decentralised randomised controlled trial. 900 individuals with T2D for ≥2 years who regularly shop for groceries will be recruited via general practices and community advertisements. Participants will be randomised to receive either: (1) access to the FoodSwitch mobile application plus standard written dietary advice, or (2) standard written dietary advice only. The FoodSwitch application allows users to scan barcodes on packaged foods to receive recommendations of healthier alternatives within the same category. The primary outcome is the difference in change in mean self-measured glycated haemoglobin between groups after 6 months. Secondary outcomes include differences in changes in waist circumference, body weight, quality of life, medication use, hospitalisations and all-cause mortality at 26 weeks. Exploratory outcomes include omics analyses. Recruitment is ongoing. Expected study completion on 31 December 2026.

The trial has received ethical approval from the Swedish Ethical Review Authority (2023-06622-01, 2024-06668-02, 2024-07357-02 and 2025-01095-02) and is performed in line with World Medical Association Declaration of Helsinki and the General Data Protection Regulation. Results will be published in a peer-reviewed international journal.

Cardiovascular autonomic neuropathy (CAN) is a serious, untreatable complication of diabetes that contributes to excess cardiovascular mortality and morbidity. CAN is associated with increased fibrosis and inflammation, possibly driven by increased sympathetic activity and overactive mineralocorticoid receptors (MRs). These may represent a potential therapeutic target. MR antagonists (MRAs) improve autonomic function in non-diabetic diseases, and finerenone, a non-steroidal MRA, has demonstrated promising results in managing diabetic kidney disease and cardiovascular complications, suggesting its potential as a novel therapy for early-stage CAN. This trial aims to evaluate whether daily administration of finerenone can modify the disease progression of early-stage CAN.

This trial is a two-centre, double-blind, parallel-group, 1:1 randomised, placebo-controlled study evaluating the effect of 78 weeks of intervention with finerenone or placebo on early-stage CAN in 100 individuals with type 2 diabetes in Denmark. The primary endpoint is the between-group difference in the expiration:inspiration ratio of the cardiovascular autonomic reflex tests (CARTs). Secondary endpoints are the between-group differences in the remaining CARTs, heart rate variability measures and fibrosis markers. Treatment effects on other forms of neuropathy and related pathological mechanisms will be explored.

The study complies with the Declaration of Helsinki and the International Counsil for Harmonisation good clinical practice guidelines, with ethics approval obtained from the Danish Medical Research Ethics Committee. All participants will provide written informed consent. Due to the risk of hyperkalaemia associated with finerenone, safety will be closely monitored throughout the study. Findings will be disseminated through peer-reviewed publications, conference presentations and clinical trial registries. A lay summary will be provided to participants on study completion.

Proactive and easily accessible interventions are needed to support people with long-term health conditions who experience limitations in activities of everyday life. However, there is a lack of interventions that promote self-management skills that prevent deterioration and improve health. The internet-based programme ‘Strategies for Empowering Activities in Everyday Life’ (SEE) supports people with long-term health conditions in developing self-management skills through knowledge, self-analysis and management strategies, promoting active and healthy daily life. This study protocol aims to evaluate the feasibility of SEE 2.0 and the study design.

This feasibility study employs a pretest and post-test design with no control group, embedded within a mixed-method approach. The participants will include 30–40 clients, occupational therapists and managers involved in delivering SEE 2.0 in primary healthcare and hospital-based services. Data will be collected through assessments and forms at baseline, 4 months and 12 months after inclusion. Additionally, qualitative methods will be used to enhance the understanding of participants’ experiences.

The study was approved by the Swedish Ethical Review Authority. The results will inform the refinement of SEE 2.0 and guide decisions on whether to proceed with planning a full-scale evaluation to assess the intervention’s effect. The results will be published in peer-reviewed scientific journals on websites and presented at conferences and seminars to reach various user groups.
