Articles

  • Improving the quality of care and expanding insurance coverage can reduce differences in outcomes experienced by different sociodemographic groups. McWilliams and colleagues used blood pressure, hemoglobin A1c, and total cholesterol measurements obtained from participants in a national survey to measure changes in chronic disease control. Over 8 years, disease control improved but gaps between white and nonwhite patients did not change. The gaps narrowed after age 65 years, when universal Medicare insurance begins.

  • Direct-to-consumer drug advertisements do not provide standardized information about the benefits and harms of the drugs. Schwartz and coworkers tested whether adding a “drug facts box” to consumer-directed drug advertisements would improve consumer knowledge and judgment. The box contained a comparison of outcomes that might occur with 2 drugs. In a randomized experiment, consumers who were shown advertisements that included the box knew more about drug benefits and side effects than consumers shown the advertisements without the box.

  • Some patients with chronic hepatitis C do not respond to initial treatment with pegylated interferon plus ribavirin. This randomized trial compared peginterferon-α2a plus ribavirin for either 48 or 72 weeks in 950 patients with hepatitis C who had not responded to peginterferon-α2b plus ribavirin. Re-treatment for 72 weeks increased sustained virologic response rates more than re-treatment for 48 weeks (16% vs. 8%), although the rates were low.

  • Cornelis and colleagues developed a genetic risk score that reflected a patient's burden of polymorphisms that prior research had linked to type 2 diabetes. They then compared the prediction of diabetes using just conventional diabetes risk factors with using both the genetic risk score and conventional predictors. Adding the genetic risk score had only a small effect on discriminating between people who developed diabetes and those who did not.

History of Medicine

  • The authors speculate that the distinctive physical features of the Egyptian pharaoh Akhenaten are due to his having 1 of 2 different familial disorders: the aromatase excess syndrome and the sagittal craniosynostosis syndrome—or a variant of the Antley–Bixler syndrome.

Clinical Guidelines

  • The U.S. Preventive Services Task Force reaffirms its 2003 recommendation on counseling to prevent tobacco use. Clinicians should ask all adults about tobacco use and provide tobacco cessation interventions for those who use tobacco products (grade A recommendation). For pregnant women, clinicians should ask about tobacco use and provide augmented, pregnancy-tailored counseling for those who smoke (grade A recommendation).

Editorials

  • In the issue, McWilliams and colleagues measured changes in disease control over time, as well as the association between Medicare coverage and disparities in these measures. Their findings, which contrast the effects of improving the quality of health care and acquiring health insurance, add to existing evidence indicating that simply improving quality of care will not eliminate disparities. They suggest that covering the uninsured is a key to reducing the sizable and persistent disparities in our country.

  • In this issue, Schwartz and colleagues found that the quality of information transfer with conventional direct-to-consumer drug advertisements was inferior to their own coherently designed drug boxes. Their studies have drawn our attention to the need for more creative thinking about how to communicate drug benefits and risks effectively and the need to study possible solutions in a methodologically rigorous manner.

On Being a Doctor

  • It was my first day in the Iraqi pediatric burn clinic, and the experience had been exhausting. The medics called me over to the newly burned 12-year-old girl who was in respiratory distress. I am an internal medicine physician in the U.S. Army completing a 15-month rotation in Iraq. I have no training in burn treatment, and I have never treated a child.
