摘要:
The leading cause of death among patients with type 2 diabetes mellitus (DM) is cardiovascular disease, with 75% of these deaths attributed to coronary heart disease. Over the previous two decades the pathophysiological basis of type 2 DM has been extensively investigated. Although many of the underlying molecular mechanisms involved in the development of this disorder remain to be explained, it is clear that type 2 DM is a complex medical disorder characterized by insulin resistance and defects in insulin secretion. The process through which the metabolic derangements of type 2 DM accelerate the development of cardiovascular disease in type 2 DM has yet to be determined and remains an area of intense investigation, focusing on hyperglycemia and insulin resistance as major underlying contributors. This article explores current information related to the pathophysiology of type 2 DM alone and its relationship to the development to cardiovascular disease.

摘要:
Genetic, environmental, and metabolic risk factors are interrelated and contribute to the development of type 2 diabetes mellitus. A strong family history of diabetes mellitus, age, obesity, and physical inactivity identify those individuals at highest risk. Minority populations are also at higher risk, not only because of family history and genetics, but also because of adaptation to American environmental influences of poor dietary and exercise habits. Women with a history of gestational diabetes as well as their children are at greater risk for progressing to type 2 diabetes mellitus. Insulin resistance increases a person's risk for developing impaired glucose tolerance and type 2 diabetes. Individuals who have insulin resistance share many of the same risk factors as those with type 2 diabetes. These include hyperinsulinemia, atherogenic dyslipidemia, glucose intolerance, hypertension, prothrombic state, hyperuricemia, and polycystic ovary syndrome. Current interventions for the prevention and retardation of type 2 diabetes mellitus are those targeted towards modifying environmental risk factors such as reducing obesity and promoting physical activity. Awareness of risk factors for developing type 2 diabetes will promote screening, early detection, and treatment in high-risk populations with the goal of decreasing both microvascular and macrovascular complications.

摘要:
Major clinical trials have shown that excellent glycemic control, sustained over time, can prevent or delay the microvascular complications of diabetes, including retinopathy, nephropathy, and neuropathy. No prospective trial has clearly shown that glycemic intervention can prevent the macrovascular complications of diabetes, such as myocardial infarction, cerebrovascular accident, and amputation. However, a number of landmark clinical trials have shown the efficacy of control of blood pressure and lipids and use of antiplatelet agents (mainly aspirin) in protecting the macrovasculature of individuals with diabetes. In this article, glycemic, blood pressure, lipid, and antiplatelet trials relevant to the treatment of people with type 2 diabetes are reviewed.

摘要:
The phenomenal growth in the rate of type 2 diabetes presents an enormous burden to society. Diabetes and its complications cost billions and significantly impact quality of life in individuals with diabetes. Diabetes management has transitioned from focusing exclusively on glycemic control to an approach that addresses both glucose abnormalities and the chronic complications of the disease. Increased understanding of the underlying mechanisms of disease and the multifactorial basis of diabetes complications suggest the importance of early diagnosis and treatment of all diabetes complications. Preventive approaches emphasizing risk factor reduction strategies are essential. The American Diabetes Association Standards of Medical Care for People with Diabetes assist both the health care provider and the individual with diabetes to appreciate the comprehensive treatment goals in diabetes and provide specific guidelines for achieving these goals. This article presents these guidelines in an easy-to-remember ABC format.

摘要:
Since 1995 there have been several new medications approved for the treatment of type 2 diabetes. The availability of these new medications has made the treatment regiment for type 2 diabetes complex. There are currently five classes of oral antidiabetic agents available in the United States. These classes include: sulfonylureas, meglitinides, α-glucosidase inhibitors, thiazolidinediones, and biguanides. Additionally there are several types of insulin and insulin analogs available for the treatment of hyperglycemia: regular, lispro, aspart, NPH, lente, ultralente, glargine, 70/30, 50/50, and 75/25. In this article, the mechanism, site of action, and adverse effects of these classes will be reviewed. The efficacy and important management issues of these glucose-lowering drugs used in monotherapy and in combination will be discussed.

摘要:
Oxidative stress occurs when there is an imbalance between free radical production and antioxidant capacity. This may be due to increased free radical formation in the body and/or loss of normal antioxidant defenses. Oxidative stress has been associated with the development of cardiovascular disease. The role of antioxidants in the primary and secondary prevention of coronary heart disease is currently under study. Although epidemiologic evidence indicates that antioxidants may decrease cardiovascular risk, clinical trial data are not conclusive. Information regarding the use and benefits of antioxidants in persons with diabetes is limited. Persons with diabetes may be more prone to oxidative stress because hyperglycemia depletes natural antioxidants and facilitates the production of free radicals. In addition, other factors such as homocysteine, insulin resistance, and aging may be contributory. This article highlights landmark clinical trials that have examined the cardioprotective effect of antioxidants. Because these trials have not been designed to study persons with diabetes, and clinical trial data for this group are not available, correlational studies are also presented. Finally, the concept of oxidative stress, the antioxidant and pro-oxidant factors that may contribute to oxidative stress, and the consequences of oxidative stress in persons with type 2 diabetes are presented.

摘要:
The purpose of this article is to describe diabetes-related research opportunities, given recent findings and recommended changes in clinical practice. The focus is on research needed to address current diabetes health problems, emphasizing prevention, management, and complications such as cardiovascular disease. The epidemiology of diabetes and how it affects the direction of research are explored. Gaps in diabetes-related research are identified. NINR research and research training opportunities are noted for investigators and nurse clinicians interested in the problems of diabetes and its complications affecting health outcomes.
