In HIV-infected patients having virologic suppression (plasma HIV RNA <50 copies/mL) with antiretroviral therapy, intermittent episodes of low-level viremia have been correlated with slower decay rates of latently infected cells and increased levels of viral evolution, but the clinical significance of these episodes is unknown. ⋯ Intermittent viremia occurred frequently and was associated with higher levels of replication (Merck 035), but was not associated with virologic failure in patients receiving initial combination therapy of indinavir-zidovudine-lamivudine (ACTG 343 and Merck 035). In this population, treatment changes may not be necessary to maintain long-term virologic suppression with low-level or intermittent viremia.

Widespread use of herbal medications among the presurgical population may have a negative impact on perioperative patient care. ⋯ During the preoperative evaluation, physicians should explicitly elicit and document a history of herbal medication use. Physicians should be familiar with the potential perioperative effects of the commonly used herbal medications to prevent, recognize, and treat potentially serious problems associated with their use and discontinuation.

Leading patient safety proposals promote the design and implementation of error prevention strategies that target systems used to deliver care and eschew individual blame. They also call for candor among practitioners about the causes and consequences of medical injury. Both goals collide with fundamental tenets of the medical malpractice system. ⋯ We tackle traditional criticisms of "no-fault" compensation systems for medical injury-specifically, concerns about their cost and the presumption that eliminating liability will dilute incentives to deliver high-quality care. Our recent empirical work suggests that a model designed around avoidable or preventable injuries, as opposed to negligent ones, would not exceed the costs of current malpractice systems in the United States. Implementation of such a model promises to promote quality by harmonizing injury compensation with patient safety objectives, especially if it is linked to reforms that make institutions, rather than individuals, primarily answerable for injuries.

The Framingham Heart Study produced sex-specific coronary heart disease (CHD) prediction functions for assessing risk of developing incident CHD in a white middle-class population. Concern exists regarding whether these functions can be generalized to other populations. ⋯ The sex-specific Framingham CHD prediction functions perform well among whites and blacks in different settings and can be applied to other ethnic groups after recalibration for differing prevalences of risk factors and underlying rates of CHD events.
