Since PCV7 (Prevnar) became available in 2000, rates of invasive pneumococcal disease have dropped sharply in the United States. Now, an expanded PCV13 vaccine that can prevent many of the remaining cases will replace PCV7.

Conflict of interest may arise when 1 physician serves 2 persons whose medical care is interdependent. In hematopoietic cell transplantation (HCT) from unrelated donors and in the setting of solid organ transplantation from living donors, the standard of care is for donors and recipients to be managed by separate physicians to provide unbiased care. However, the practice patterns of evaluation and care of related donors and recipients are not well described. A survey of HCT centers in the United States was conducted by the Donor Health and Safety Working Committee of the Center for International Blood and Marrow Transplant Research to determine the type of provider involved in medical clearance, informed consent, and medical management of hematopoietic cell collection and the relationship of that provider to the HC transplant recipient. The response rate was 40%. In greater than 70% of centers, transplantation physicians were involved or potentially involved in overlapping care of the HC transplant donor and the recipient. These patterns were similar between transplantation teams caring for adult or pediatric donors and recipients. Among responding centers, medical management of recipients and their related donors by the same provider is common, a practice that has the potential for conflict of interest.

Hepatitis C, a common chronic bloodborne infection, is found in approximately 2 percent of adults in the United States. Chronic infection is associated with serious morbidity and mortality (e.g., cirrhosis, hepatocellular carcinoma). Testing for hepatitis C is recommended for at-risk populations, and confirmatory testing includes quantification of virus by polymerase chain reaction. The U.S. Preventive Services Task Force recommends against routine screening for hepatitis C virus infection in asymptomatic adults who are not at increased risk of infection (general population). It found insufficient evidence to recommend for or against routine screening in adults at high risk of infection. Current therapy for chronic hepatitis C virus includes pegylated interferon and ribavirin. Therapy is based on factors that predict sustained virologic response, and the goal of therapy is to slow or halt progression of fibrosis and prevent the development of cirrhosis. In the future, multidrug regimens in combination with current therapies may be developed. Patients with chronic hepatitis C virus infection should be advised to abstain from alcohol use. Currently, there is no vaccine available to prevent hepatitis C virus infection; however, persons infected with hepatitis C virus should be vaccinated for hepatitis A and B. The American Association for the Study of Liver Diseases recommends ultrasound surveillance for hepatocellular carcinoma in persons with chronic hepatitis C virus infection and cirrhosis.
