More than half of enrollees in the U.S. Department of Veterans Affairs (VA) are also covered by Medicare and can choose to receive their prescriptions from VA or from Medicare-participating providers. Such dual-system care may lead to unsafe opioid use if providers in these 2 systems do not coordinate care or if prescription use is not tracked between systems.

The association between fever and neutropenia and the risk for life-threatening infections in patients receiving cytotoxic chemotherapy has been known for 50 years. Indeed, infectious complications have been a leading cause of morbidity and mortality in patients with cancer. This review chronicles the progress in defining and developing approaches to the management of fever and neutropenia through observational and controlled clinical trials done by single institutions, as well as by national and international collaborative groups. The resultant data have led to recommendations and guidelines from professional societies and frame the current principles of management. Recommendations include those guiding new treatment options (from monotherapy to oral antibiotic therapy) and use of prophylactic antimicrobial regimens in high-risk patients. Of note, risk factors have changed with the advent of hematopoietic cytokines (especially granulocyte colony-stimulating factor) in shortening the duration of neutropenia, as well as with the discovery of more targeted cancer treatments that do not result in cytotoxicity, although these are still the exception. Most guiding principles that were developed decades ago-about when to begin empirical treatment after a neutropenic patient becomes febrile, whether and how to modify the initial treatment regimen (especially in patients with protracted neutropenia), and how long to continue antimicrobial therapy-are still used today. This review describes how the treatment principles related to the management of fever and neutropenia have responded to changes in the patients at risk, the microbes responsible, and the tools for their treatment, while still being sustained over the arc of time.

Pharmacoepidemiologic and pharmacoeconomic analysis of health care databases has become a vital source of evidence to support health care decision making and efficient management of health care organizations. However, decision makers often consider studies done in nonrandomized health care databases more difficult to review than randomized trials because many design choices need to be considered. This is perceived as an important barrier to decision making about the effectiveness and safety of medical products. Design flaws in longitudinal database studies are avoidable but can be unintentionally obscured in the convoluted prose of methods sections, which often lack specificity. We propose a simple framework of graphical representation that visualizes study design implementations in a comprehensive, unambiguous, and intuitive way; contains a level of detail that enables reproduction of key study design variables; and uses standardized structure and terminology to simplify review and communication to a broad audience of decision makers. Visualization of design details will make database studies more reproducible, quicker to review, and easier to communicate to a broad audience of decision makers.

Hashimoto disease is a chronic autoimmune thyroiditis. Despite adequate hormone substitution, some patients have persistent symptoms that may be the result of immunologic pathophysiology.

The role of internists in evaluating obesity is to assess the burden of weight-related disease, mitigate secondary causes of weight gain (medications, sleep deprivation), and solicit patient motivation for weight loss. Internists should assess these factors and emphasize the importance of weight loss for the individual patient. All patients wishing to lose weight should be encouraged to monitor their diet and physical activity and should be referred to high-intensity behavioral programs. Some patients with obesity may also benefit from pharmacotherapy or bariatric surgery.
