The genetic bases of peak bone mass in males, as determinants of an individual’s risk of developing osteoporotic fractures in old age and their interaction with dietary and lifestyle factors are still poorly understood. Our objective was to examine the relative contribution of genetic and environmental variables to the regulation of peak bone mass in a population-based cohort of young healthy men, focusing on the BsmI polymorphism of vitamin D receptor (VDR)gene and the AluI...
The primary objective of the present study is to determine the clinical, biological and genetic determinants of the anticoagulant activity in patients treated with either anti-IIa or anti Xa oral anticoagulants. The secondary objective is to determine the clinical, biological or genetic determinants of hemorrhagic or thrombotic complications during a one year follow-up. Results will lead to a better prediction of both drug response and risk of complications.
The purpose of this study is to identify genetic determinants and environmental factors that will help identify patients who are prone to develop recurrent colon cancer following surgical resection of American Joint Committee on Cancer (AJCC) stage II (T3-4N0M0) patients and stage III (TxN1-3M0) colon carcinoma despite the use of adjuvant chemotherapy and physician surveillance.
More than 1,000 obese people are screened for genetic mutations (MC4R). Those with positive screenings as well as 320 randomly selected people without MC4R mutations are randomized to 2 consultation types: one including recommendations for eating and physical activity behavior, the other with an additional part on genetic determinants and actions in obesity. It is hypothesized that obese people with obesity-specific genetic mutations, and obese people with a family history of o...
The Pima Indians of Arizona have the highest prevalence and incidence of type 2 diabetes of any population in the world. Prospective analyses in this population have identified insulin resistance and a defect in early insulin secretion as risk factors for the development of the disease. A recent longitudinal analysis which tracked the development of diabetes in 17 Pima Indians demonstrated that both insulin action and early insulin secretion deteriorate as individuals progres...
Background: - Nasopharyngeal carcinoma (NPC) a common malignant tumor in southern China and Southeast Asia. Infection with Epstein-Barr virus is believed to be necessary for the development of NPC; non-viral environmental factors, such as dietary consumption of nitrosamines, cigarette smoking, betel nut chewing, wood dust exposure and possibly exposure to formaldehyde, have been implicated in the disease. Genetic susceptibility may also play an important role in the deve...
RATIONALE: Gathering information about genetic and environmental factors may help doctors understand why African American men have an increased risk of prostate cancer and die more often from prostate cancer than Caucasian men. PURPOSE: This clinical trial is studying genetic and environmental risk factors in African American and Caucasian healthy men and in patients with prostate cancer.
To analyze the genetic and environmental contributions of juvenile hemodynamic determinants of blood pressure, including cardiac output and systemic vascular pressure, to adult cardiovascular risk.
The objective of this study is to investigate the effect of parental peri-natal environmental risk factors and genetic factors on the development of Congenital Heart Disease (CHD). Our hypothesis is that the distributions of some environmental and genetic risk factors significantly differ between neonates with and without CHD.
The investigators established the Faroese Alzheimer's Cohort with the aim to unravel genetic and environmental factors that influence the risk and/or susceptibility of Alzheimers disease (AD). It is believed the Faroese population represents a unique opportunity due to its characteristics as a geographic, environmental and genetic isolate with a homogeneous genetic background and founder effects. It has an 'engaged' population with superbly detailed genealogy going 400 years ba...
RATIONALE: Gathering information about gene mutations and environmental exposure may help doctors learn more about the causes of retinoblastoma in young patients. PURPOSE: This laboratory study is looking at genetic mutations and environmental exposure in young patients with retinoblastoma and in their parents and young healthy unrelated volunteers.
The main purpose of this study is to look for genetic and environmental risk factors of cervical artery dissections, a major cause of ischemic stroke in young adults, in a large multicenter case-control trial
People with atopic dermatitis (AD), or eczema, are susceptible to skin infections and inflammations. Some individuals with AD develop a condition known as eczema herpeticum (EH) following exposure to the herpes simplex virus (HSV). The purpose of this study is to identify the genetic determinants that lead people with AD to develop EH and similar conditions caused by other viruses.
The goal of this study is to identify the modifying genes and environmental features that regulate the clinical expression of mutations in bone morphogenetic protein receptor 2 (BMPR2); to develop the understanding of how BMPR2 mutations result in disease; and to identify the undiscovered genetic mutations that cause primary pulmonary hypertension (PPH).
To identify and evaluate genetic and non-genetic determinants of coronary heart disease (CHD), atherosclerosis, and their risk factors in ongoing population-based epidemiology studies. The multicenter study was conducted in three phases which were: Phase I, the family history component: Phase II, the clinical examination and follow-up component; and Phase III, the molecular genetic and genetic epidemiology studies component.
RATIONALE: Environmental exposure and genetic predisposition may affect the risk of developing cancer later in life. Learning about genetic markers and the long-term effects of environmental exposure may help the study of lung cancer in the future. PURPOSE: This research study is looking at risk factors and genetic markers in healthy participants and in patients with lung cancer.
The response to opioids varies greatly among individuals. Some of these variability is accounted for by genetic factors. The present study was designed to evaluate the possibility that genetic polymorphism in the gene encoding for mu opioid receptor may explain variability in the response to alfentanil during lithotripsy.
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a fatal neurodegenerative disease that poses a significant burden for affected individuals and their family members. The principal objective of this epidemiologic study is to identify environmental and genetic risk factors for ALS. Of primary interest is whether environmental chemicals such as heavy metals, pesticides and organic solvents contribute to the cause of ALS. We also aim to identify geneti...
The maintenance of health and the progression of disease are associated with an individual's genetic make-up and environmental factors, including lifestyle choices (such as diet, exercise, behaviors, stressors, sleep, tobacco and alcohol use), environmental exposures and socioeconomic determinants. Environmental factors have been shown to influence, sometimes rapidly, epigenetic processes thereby influencing genetic expression. Regulation of the human genome by the epigenome is...
