Monocyte Gene Expression Signature of Patients with Early Onset Coronary Artery Disease

The burden of cardiovascular disease (CVD) cannot be fully addressed by therapy targeting known pathophysiological pathways. Even with stringent control of all risk factors CVD events are only diminished by half. A number of additional pathways probably play a role in the development of CVD and might serve as novel therapeutic targets. Genome wide expression studies represent a powerful tool to identify such novel pathways. We compared the expression profiles in monocytes from twenty two young male patients with premature familial CAD with those from controls matched for age, sex and smoking status, without a family history of CVD. Since all patients were on statins and aspirin treatment, potentially affecting the expression of genes in monocytes, twelve controls were subsequently treated with simvastatin and aspirin for 6 and 2 weeks, respectively

Linkage study of fibrinogen levels: the Strong Heart Family Study

<p>Abstract</p> <p>Background</p> <p>The pathogenesis of atherosclerosis involves both hemostatic and inflammatory mechanisms. Fibrinogen is associated with both risk of thrombosis and inflammation. A recent meta-analysis showed that risk of coronary heart disease may increase 1.8 fold for 1 g/L of increased fibrinogen, independent of traditional risk factors. It is known that fibrinogen levels may be influenced by demographic, environmental and genetic factors. Epidemiologic and candidate gene studies are available; but few genome-wide linkage studies have been conducted, particularly in minority populations. The Strong Heart Study has demonstrated an increased incidence of cardiovascular disease in the American Indian population, and therefore represents an important source for genetic-epidemiological investigations.</p> <p>Methods</p> <p>The Strong Heart Family Study enrolled over 3,600 American Indian participants in large, multi-generational families, ascertained from an ongoing population-based study in the same communities. Fibrinogen was determined using standard technique in a central laboratory and extensive additional phenotypic measures were obtained. Participants were genotyped for 382 short tandem repeat markers distributed throughout the genome; and results were analyzed using a variance decomposition method, as implemented in the SOLAR 2.0 program.</p> <p>Results</p> <p>Data from 3535 participants were included and after step-wise, linear regression analysis, two models were selected for investigation. Basic demographic adjustments constituted model 1, while model 2 considered waist circumference, diabetes mellitus and postmenopausal status as additional covariates. Five LOD scores between 1.82 and 3.02 were identified, with the maximally adjusted model showing the highest score on chromosome 7 at 28 cM. Genes for two key components of the inflammatory response, i.e. interleukin-6 and "signal transducer and activator of transcription 3" (<it>STAT3</it>), were identified within 2 and 8 Mb of this 1 LOD drop interval respectively. A LOD score of 1.82 on chromosome 17 between 68 and 93 cM is supported by reports from two other populations with LOD scores of 1.4 and 1.95.</p> <p>Conclusion</p> <p>In a minority population with a high prevalence of cardiovascular disease, strong evidence for a novel genetic determinant of fibrinogen levels is found on chromosome 7 at 28 cM. Four other loci, some of which have been suggested by previous studies, were also identified.</p

Development and Evolution of a Model Interprofessional Education Program in Parkinson’s disease: A Ten-year Experience

OBJECTIVE This paper describes development, evolution and learner reactions in a model interprofessional education program for medical, nursing, physician assistant, occupational therapy, physical therapy, music therapy, social work and speech-language pathology practitioners. Sponsored by the National Parkinson Foundation (NPF) (currently Parkinson’s Foundation), Allied Team Training for Parkinson (ATTP) is a U.S.-based multi-day interprofessional education program in best practices for integrated, interprofessional team-based Parkinson’s disease (PD) care. NPF sponsored 26 ATTP trainings from 2003 to 2013. METHODS This mixed methods evaluation uses case study document review and observation to outline ATTP curriculum development, evolution, and implementation challenges. Learner-perceived effectiveness ratings, knowledge change, pre-post ratings on the Team Skills Scale, confidence in working with people with PD and caregivers, and trainee-reported practice changes at 6-month follow-up were collected. RESULTS Qualitative results identified multiple factors in building an effective interprofessional education program, including interprofessional team practice opportunities through case-based learning, engaging care networks and continuous feedback loops for program improvement. Quantitative results showed that trainees across professions, geographic regions and work settings rated the overall program and curriculum effectiveness, amount of new knowledge and knowledge change very highly. ATTP resulted in significant post-training improvement in team skills, confidence in working with PD, and post-training self-reported practice changes. CONCLUSION Findings suggest that ATTP is an effective interprofessional education program that could be replicated or adapted to other settings and neurodegenerative or chronic illnesses. The model of combining interprofessional team training with disease-specific curriculum content appears to be an effective “next practice” in continuing professional development
