OBJECTIVES: Vascular Disease is the leading cause of complications and death in patients with diabetes. Risk markers and underlying mechanisms have not been fully elucidated, and may differ from those in non-diabetic individuals. The unifying theme for the Program Project is that hyperglycemia and insulin resistance alter a number of biological processes which interact in vicious cycles to accelerate atherogenesis and are consequently major underlying risk factors for vascular disease. The overall objectives are to define these unique processes and to elucidate underlying biochemical, metabolic, and genetic determinants of vascular disease complications in diabetes. RESEARCH PLAN: Over the past 4 years, we have collaborated with the DCCT/EDIC Study Group, and have made novel observations regarding vascular disease pathogenesis in Type 1 Diabetes. This work has focused our studies on specific pathogenic processes. We will now study a Type 2 Diabetes cohort from the VA Cooperative Study, "Glycemic Control and the Complications of Diabetes, Type 2", with high vascular disease event rates. These collaborations provide a unique opportunity to address the pathogenesis of accelerated atherogenesis in the two main types of diabetes, and will greatly augment the scientific knowledge that will be gained in the conduct of these world-class prospective trials. METHODS: The Program Project has 4 projects and 3 cores. Project 1 will assess lipoproteins, glycoxidative stress, and inflammation as risk factors in studies involving Type 2 Diabetes patients and cultured cell systems. Based on preliminary data from our initial studies Type 1 patients, changes in the NMR lipoprotein subclass profile will be emphasized. Project 2 will elucidate interactions between inflammation, modifications of lipoproteins, and autoimmunity in vascular disease risk. These novel concepts are also based upon exciting preliminary data pertaining to LDL-antibody complexes. Project 3 will pursue interesting preliminary data and define the role of the kallikrein-kinin system in vascular disease complications, with effects on mitogenesis and matrix production. Project 4 will assess the role of the Insulin Resistance Syndrome and novel factors secreted from adipocytes in the pathophysiology of biochemical risk factors and cardiovascular complications. Cores include an Administrative Core, a Biostatistics and Epidemiology Core which will link with the trials data coordinating centers, and Molecular and Statistical Genetics Core. Investigators will work in close collaboration with the VA Executive Committee, Study Centers, the Hines Coordinating Center, and some of the other ancillary studies. All data analysis involving clinical outcomes will be performed at the Hines Coordinating Center. There is true synergism among the projects at both scientific and logistical levels. The Program Project design allows for interactions among multidisciplinary investigators studying the same cohort, which will define how multiple pathological processes interact at the level of the arterial wall to promote atherosclerosis.

TITLE: CSP 465-C, Fatty Acid Binding protein 2 (FABP2) ancillary proposal to CSP# 465 Glycemic Control and Complications in Diabetes Mellitus Type 2. Angeliki Georgopoulos, M.D. Carlos Abraira M.D. William Duckworth M.D. Fatty acid binding protein 2 (FABP2) is involved in the transport of long chain fatty acids across the intestinal epithelium. A common (40-45%) polymorphism of FABP2 gene (codon 54 Threonine for Alanine) results in increased intestinal fatty acid absorption and triglyceride secretion (Baier et al J Clin Invest 95:1281-87, 1995; Baier et al J Biol Chem 271: 10892-10896,1996). We have found (JCEM 85:3155-60, 2000) that in patients with type 2 diabetes, the codon 54 polymorphism of the FABP2 results in fasting and postprandial hypertriglyceridemia. Since hypertriglyceridemia is a risk factor for atherosclerosis in type 2 diabetes and it is part of the insulin resistance syndrome, the objective of this ancillary study would be to screen the participants of the CSP# 465 study for the polymorphism and assess a) whether those carrying the polymorphism respond differently to the various treatment modalities and b) whether they develop more cardiovascular events compared to the ones lacking the polymorphism. There is one study that suggests an association of the polymorphism with a history of parental stroke (JCEM 85:2801-4, 2000). The only additional request from the study participants will be to agree to the collection of a blood sample to be used for DNA isolation and screening for the polymorphism. No additional funds are requested. If this polymorphism proves to be a predictor of either the response to a specific treatment modality or of the risk to macro-vascular complications, it will be very easy to screen for it and target our treatment modalities appropriately.
NCT00168831
To evaluate the long term effects of treatment with two doses of Tiotropium delivered by the Respimat inhaler in patients with COPD.
NCT00004859
This randomized phase III trial is studying carboplatin, paclitaxel, radiation therapy, and thalidomide to see how well they work compared to carboplatin, paclitaxel, and radiation therapy alone in treating patients with newly diagnosed stage III non-small cell lung cancer. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Thalidomide may stop the growth of non-small cell lung cancer by stopping blood flow to the tumor. It is not yet known if combination chemotherapy plus radiation therapy is more effective with or without thalidomide.
NCT01839045
The major purpose of this study is to evaluate a laboratory developed test that measures multiple breast cancer-specific biomarker proteins in your blood samples. The biomarker results along with your personal medical profile will be evaluated to determine your risk for the presence of a malignancy in the breast as compared to your breast evaluation assessment conducted by your physician.
NCT01142193

The NuBac device is indicated for reconstruction following nucleotomy in skeletally mature patients at least 18 years of age with symptomatic single level degenerative disc disease (DDD) at L4/L5 only. DDD is defined as discogenic back pain with or without leg pain; with degeneration of the disc as confirmed by patient history, physical examination, radiographic studies showing: decreased disc height, contained herniated nucleus, vacuum phenomenon (dark disc) OR positive discography at the affected level. These DDD patients should have no more than Grade 1 spondylolisthesis at the involved level and should have failed at least six months of conservative, non-operative care. Demonstrate non-inferiority compared to ProDisc.

NCT00047385
RATIONALE: Effective screening tests should help doctors detect lung cancer early and plan curative treatment. It is not yet known whether low-dose helical computed tomography (LDCT) screening is more effective than chest radiography (CXR) screening in reducing death from lung cancer. PURPOSE: Randomized clinical trial to compare the effectiveness of LDCT scan with that of CXR in screening individuals who are at high risk for developing lung cancer.
NCT00425321
The primary objective of the study is to evaluate the safety and tolerability of 100, 200, and 300 mg/day doses of RWJ-445380 for up to 12 weeks in patients with active Rheumatoid Arthritis despite methotrexate therapy.
NCT01211678
The primary objective of this study was to validate the ability of an 8-gene biomarker set to differentiate between participants who met or did not meet European League Against Rheumatism (EULAR) Disease Activity Score (DAS)-28 Good Response criteria after treatment with anti-Tumor Necrosis Factor (TNF) therapy for 14 weeks in approximately 200 anti-TNF-naïve participants. The secondary objectives of this study was (i) to compare the behavior of the 8-gene marker set in participants who were anti-TNF naïve versus those who began their second anti-TNF treatment , (ii) to develop, maintain, and utilize a biorepository of serum, plasma, RNA, and deoxyribonucleic acid (DNA) samples for additional experiments and analyses and (iii) to discover novel genetic (DNA) predictors of response to anti-TNF therapy.
