Elucidating The Genetic Determinants Of The Archetypal Complex Disease Hypertriglyceridemia, Christopher T. Johansen

Electronic Thesis and Dissertation Repository

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in Canada. Among non-traditional risk factors, plasma triglyceride (TG) concentration is re-emerging as a significant risk factor. Patients with hypertriglyceridemia (HTG) – an archetypal complex phenotype defined by fasting plasma TG concentration >95^th percentile – thus have significantly increased CVD risk, compounded by associated co-morbidities such as obesity, metabolic syndrome and type 2 diabetes. However, the molecular pathways contributing to HTG susceptibility are incompletely defined. A better understanding of the genetic determinants that underlie the phenotypic spectrum of plasma TG and HTG susceptibility is necessary to identify novel …

Childhood Meat Eating And Inflammatory Markers: The Guangzhou Biobank Cohort Study, Mary Schooling, Chao Q. Jiang, Tai H. Lam, W. S. Zhang, Kar Keung Cheng, Gabriel M. Leung

Publications and Research

Background
We hypothesized that socio-economic development could, via nutritionally driven levels of pubertal sex-steroids, promote a pro-inflammatory state among men but not women in developing countries. We tested this hypothesis, using recalled childhood meat eating as a proxy for childhood nutrition, in southern China.

Methods
We used multivariable linear regression in the Guangzhou Biobank Cohort Study phase 3 (2006-8) to examine the adjusted associations of recalled childhood meat eating, <1/week (n = 5,023), about once per week (n = 3,592) and almost daily (n = 1,252), with white blood cell count and its differentials among older (≥50 years) men (n = 2,498) and women (n = 7,369).

Results
Adjusted for age, childhood socio-economic position, education and smoking, childhood meat eating had sex-specific associations with white blood cell count and lymphocyte count, but not granulocyte count. Men with childhood …

Cardiovascular Risk Scores Do Not Account For The Effect Of Treatment: A Review, Su May Liew, Jenny Doust, Paul Glasziou

Objective - To compare the strengths and limitations of cardiovascular risk scores available for clinicians in assessing the global (absolute) risk of cardiovascular disease.Design - Review of cardiovascular risk scores.Data sources - Medline (1966 to May 2009) using a mixture of MeSH terms and free text for the keywords ‘cardiovascular’, ‘risk prediction’ and ‘cohort studies’.Eligibility - criteria for selecting studies A study was eligible if it fulfilled the following criteria: (1) it was a cohort study of adults in the general population with no prior history of cardiovascular disease and not restricted by a disease condition; (2) the primary objective …

A Prospective Study Of Positive Psychological Well-Being And Coronary Heart Disease, Julia K. Boehm, Christopher Peterson, Mika Kivimaki, Laura D. Kubzansky

Psychology Faculty Articles and Research

Objective: Research suggests that positive psychological well-being is associated with cardiovascular health. However, much of this research uses elderly samples and has not determined the pathways by which psychological well-being influences cardiovascular disease or whether effects are similar for men and women. This study investigates the association between two aspects of well-being (emotional vitality and optimism) and coronary heart disease (CHD) in a sample of middle-aged men and women, and considers potential mediating factors.

Method: Between 1991 and 1994, well-being and coronary risk factors were assessed among 7,942 individuals without a prior cardiovascular event from the Whitehall II …

Development Of A Positive Psychology Intervention For Patients With Acute Cardiovascular Disease, Jeff C. Huffman, Carol A. Mastromauro, Julia K. Boehm, Rita Seabrook, Gregory L. Fricchione, John W. Denninger, Sonja Lyubomirsky

Psychology Faculty Articles and Research

The management of depression and other negative psychological states in cardiac patients has been a focus of multiple treatment trials, though such trials have not led to substantial improvements in cardiac outcomes. In contrast, there has been minimal focus on interventions to increase positive psychological states in cardiac patients, despite the fact that optimism and other positive states have been associated with superior cardiovascular outcomes. Our objective was to develop an 8-week, phone-based positive psychology intervention for patients hospitalized with acute cardiac disease (acute coronary syndrome or decompensated heart failure). Such an intervention would consist of positive psychology exercises adapted …

Effects Of Calcium Supplementation On Cardiovascular Disease In Postmenopausal Women, Raizel Robinson

The Science Journal of the Lander College of Arts and Sciences

The following is an excerpt from the introduction of the article: In the United States, 53% of the population use dietary supplements. Of the people using supplements, 43% use calcium and 37% use vitamin D. However, 63% of women older than 60 years of age reported using dietary supplements (Park et al., 2009). Calcium supplementation, without co-administered vitamin D, increases the risk of myocardial infarction and cardiovascularrelated diseases among postmenopausal women. On the contrary, calcium supplementation with accompanied vitamin D may not produce similar effects.
