OBJECTIVE To estimate the average postponement of death in statin trials. SETTING A systematic literature review of all statin trials that presented all-cause survival curves for treated and untreated. INTERVENTION Statin treatment compared to placebo. PRIMARY OUTCOME MEASURES The average postponement of death as represented by the area between the survival curves. RESULTS 6 studies for...

BACKGROUND Stroke is a leading cause of death and disability. Although clinical trials of the early lipid-lowering therapies did not demonstrate a reduction in the rates of stroke, data from recently completed statin trials strongly suggest benefit. METHODS AND RESULTS The effect of pravastatin 40 mg/d on stroke events was investigated in a prospectively defined pooled analysis of 3 large, pl...

Communicable diseases are still major causes of deaths in developing countries. Cancer incidence, however, increased 19% between 1990 and 2000, mainly in this same developing world (Stewart and Kleihaus, 2003), and malignant neoplasms are now the second leading cause of mortality in these countries (WHO, 2003). Limitations of medical facilities and equipment mean that prevention is indispensabl...

Strategies for the prevention of cancer include those aimed at reducing the incidence of cancer (primary prevention) and cancer mortality through early detection of tumors (secondary prevention). The efficacy of prevention interventions is evaluated by clinical trials. The conduct of clinical trials is aided by the use of serological indicators of the carcinogenic process measured using plasma ...

The incidence of cervical cancer is declining slowly necessitating concerted and organized control measures. Control through primary prevention has become a distinct reality though a prophylactic vaccine, which may take quite some time for its widespread use. Thus control of cervical cancer through secondary preventive measures is the only viable solution now. While high quality cytology screen...

A recent meta-analysis of selected randomized clinical trials (RCTs), in which population groups of differing ages and health status were supplemented with various doses of β-carotene, vitamin A, and/or vitamin E, found that these interventions increased all-cause mortality. However, this meta-analysis did not consider the rationale of the constituent RCTs for antioxidant supplementation, none ...

BACKGROUND There is consensus that development and evaluation of a systems-oriented approach for child obesity prevention and treatment that includes both primary and secondary prevention efforts is needed. This article describes the study design and baseline data from the Texas Childhood Obesity Research Demonstration (TX CORD) project, which addresses child obesity among low-income, ethnicall...

A brief summary of the revised NCEP guidelines for the detection, evaluation, and treatment of high blood cholesterol levels in adults is presented. The major changes in the current guidelines are the inclusion of three categories of CHD risk, one for secondary prevention and two for primary prevention based upon a combination of LDL-c levels and the number of other risk factors. Age and gender...

Health promotion and disease prevention programs are becoming important components of contemporary health care. There are at least 2 pathways to the enhancement of population health status through disease prevention. The first pathway requires the early diagnosis and treatment of disease. The second pathway promotes healthy lifestyles and disregards the requirement that a condition must be diag...

Most heart failure research and quality improvement efforts are targeted at treatment and secondary prevention of patients with manifest heart failure. This is distinct from coronary disease where primary prevention has been a focus for over three decades. Given the current importance and the projected worsening of heart failure epidemiology, a more focused effort on prevention is urgently needed.
