The Genetic, Protein, and Lipid Basis of Variation in Cholesterol Efflux

The rationale of this research is that deep phenotyping of individuals at the extremes of cholesterol efflux will identify key determinants of efflux that are potential novel therapeutic targets to prevent or reverse Atherosclerotic Cardiovascular Disease (ASCVD). The investigators propose to carry out the objective by studying participants at extreme low and high cholesterol efflux identified from the investigator's study in the population-based Dallas Heart Study by accomplishing the following aims: 1) determine the heritability of and genomic factors associated with cholesterol efflux by establishing a family pedigree of extreme low and high efflux and sequencing candidate genes involved in HDL metabolism; and 2) identify the protein and lipid signature of extreme low and high cholesterol efflux in a sex- and ethnicity-specific manner using mass spectroscopy and ELISA in FPLC-derived fractions. The investigators expect to identify genetic variants and sex- and ethnicity-specific combinations of proteins and lipids in participants with extreme low and high efflux that may lead to novel ways to modulate efflux. This proposal leverages a well-phenotyped population-based study to characterize the gene-protein-lipid signature of 1) extremes of cholesterol efflux in a sex- and ethnicity-specific manner. Successful completion of these aims will have immediate and direct impact on the use of cholesterol efflux as a clinically relevant biomarker of therapeutic benefit and are necessary for the clinical development of appropriate new targets for manipulation of the key atheroprotective function of cholesterol efflux to reduce ASCVD.

Effects of 10 Weeks of Lifestyle Coaching on Cardiometabolic Risk Factors, Workability and Subjective Wellbeing

The main purpose of this study is to understand the impact of lifestyle coaching on the risk of future cardiometabolic disease, workability and self-assessed wellbeing. The data gathered during the study helps in the future to better identify different focus groups for more tailored interventions. The study consists of two main stages: screening and coaching phase. Screening Aava and the pension will recruit 2000 participants for screening from the employer companies. Screening participants are invited to answer a wellbeing questionnaire (Aava Virta questionnaire, Work Ability Index questionnaire) and give blood samples and physiological measurements, including weight, height, waist circumference, neck circumference and blood pressure. All subjects participating in screening will receive the results from wellbeing questionnaire immediately and they receive the results from blood test within few weeks. Of these 2000 screened persons, a total of 300 high-risk (according to ApoB/ApoA1) individuals and 600 medium-risk individuals will be selected to participate in the coaching phase. These participants are randomly split into treatment and control groups, so that eventually 150 high-risk and 300 medium-risk individuals are placed in both groups. Therefore, a total of 900 subjects carry forward to the coaching phase and in 1100 subjects the study ends. All 900 subjects entering coaching phase receive home a Firstbeat Bodyguard 2 device with instructions for performing Firstbeat wellbeing analysis. After the measurement the device is posted back for analysis according to instructions. The results and feedback from this test is received in the end of the study after the coaching phase. Stage 2: Coaching phase Within the coaching groups, participants in the high-risk category and treatment group undergo an individual coaching program. Participants in the medium-risk category undergo a group coaching program with similar aims. Both coaching programs last 10 weeks during which there are 8 almost weekly coaching sessions at the subjects worksite or near vicinity. Both coaching programs aim in reducing cardiometabolic risk factors and improving subjective well-being. The topics of the lifestyle coaching are 1) nutrition, 2) physical activity, 3) sleep and stress and 4) the long-term maintenance of lifestyle changes. The aims and methods in each coaching topic is based on Finnish recommendations on the topic. The coaching sessions include mostly discussions but in the sessions focusing more on physical activity there are also sessions including activity. In the halfway (5 weeks) of coaching phase, a second blood sampling and Aava wellbeing questionnaire are taken from all subjects (both coaching and control groups). In the end of the coaching phase (10 weeks) blood samples, Aava wellbeing questionnaire, Work Ability Index -questionnaire and physiological measurements are taken the last time. At this stage a second Firstbeat analysis is also performed. BBI-15 questionnaire is administered before and after the coaching phase. An open ended questionnaire regarding lifestyle change motivators and experiences before, during and after the coaching phase is administered to all participants. Also, a small subset (20 persons) of subjects takes in interviews to delve more detailed to the experiences during the study. End of coaching phase and study - start of feedback and analysis After the coaching phase has ended and the subjects (coaching and their control groups) have received all the results (wellbeing questionnaire, blood tests and Firstbeat results) for the study and feedback sessions will be held for all. Willing subjects also receive the results from the gene test in form of PRS scores ie. total genetic risk for three areas of health: heart disease, type 2 diabetes and obesity. THL gene results do not identify single gene variants. After this feedback session the study has ended for the subject. After all data in the study has been gathered starts the analysing and reporting phase for the researchers. At this stage the researchers can retrieve data from Aava patient records to analyse the effect of earlier diagnoses and findings. The information retrieved relate to ICD-10 diagnosis codes C00-C97 (malignant neoplasms), E00-E89 (endocrine, nutritional and metabolic diseases), F00-F99 (mental, behavioral and neurodevelopmental disorders), I00-I99 (diseases of the circulatory system) and M00-M99 (diseases of the musculoskeletal system and connective tissue) as these diagnostic codes can be important background factors for biomarkers of CVD and Type 2 diabetes risk and to some of the secondary endpoints like workability.
