This review summarizes recent trends and current patterns of tobacco use in the United States. Although adult smoking dropped between 1965 and 1990, from 50% to 28% of men and from 35% to 23% of women, the past decade has seen little further progress. In 2000, 25.7% of US men and 21.0% of women were smokers. ⋯ Bidis and kreteks may be gaining popularity among young people, and more than 15% of adolescent smokers use these tobacco products. Despite recent progress, tobacco use remains prevalent in the United States. State and local governments need to invest adequate resources in the full range of tobacco control activities.

A general medicine consult service can be difficult to manage because house staff are unaccustomed to the consultant role, the required knowledge is new and diverse, and the curriculum may be poorly defined. Within the last 3 decades, perioperative consultation has been more rigorously studied and a more evidence-based method has emerged. The consultative service at the University of Tennessee has developed a systematic approach to medical consultation that provides efficient, evidence-based patient care along with resident education. The curricular model, which reflects the newly required competencies of the American Board of Internal Medicine and the Residency Review Committee, is transferable to most training settings.

Review Comparative Study
From 1960s Evans County Georgia to present-day Jackson, Mississippi: an exploration of the evolution of cardiovascular disease in African Americans.
Cardiovascular disease (CVD) is the No. 1 cause of mortality in the United States and it disproportionately affects African Americans. However, there are earlier reports that African Americans had significantly less CVD than whites. This racial discrepancy in CVD rates was noticed primarily for coronary heart disease (CHD). ⋯ However, the rate of decline of CVD in African Americans has not been equal to that seen in whites, such that African Americans now have a disproportionate share of CVD in the United States. In the 1990s, the Jackson Heart Study was designed to explore the reasons for the current racial discrepancy. This articles reviews the findings of the Evans County Study and explores various hypotheses for why CVD in African Americans has evolved from a disease from which African Americans may have been "protected" to one in which they shoulder a disproportionate burden.

This article provides an overview of the evidence on the ways racism can affect the disproportionate rates of cardiovascular disease (CVD) in African Americans. It describes the significant health disparities in CVD for blacks and whites and suggests that racial disparities should be understood within the context of persistent inequities in societal institutions and relations. Evidence and potential pathways for exploring effects of 3 levels of racism on cardiovascular health risk factors and outcomes are reviewed. ⋯ Few population-based studies have examined the relationship between racism and CVD. The findings, though suggestive of a positive association, are neither consistent nor clear. The research agenda of the Jackson Heart Study in addressing the role of racism in CVD is presented.

Review Comparative Study
Potential role of increased iron stores in diabetes.
Diabetes mellitus (DM) is an important risk factor for the development of cardiovascular disease. Extensive clinical, epidemiologic, and basic studies suggest that excessive tissue iron stores may contribute to the occurrence and complications of DM. Secondary diabetes occurs in inherited pathologic iron overload syndromes of European- and African-derived populations and is an established complication of transfusional iron overload. ⋯ Iron reduction therapy in hereditary hemochromatosis and transfusional iron overload is associated with improved glucose tolerance and reduced incidence of secondary diabetes. Trials of iron reduction therapy in diabetes mellitus, although limited and inconclusive, have shown clinical improvement in some patients. The current article reviews evidence suggesting that tissue iron contributes to DM and its complications and presents preliminary data that emphasize the potential importance of iron overload in DM of African Americans.
