Introduction: Pregnant and lactating people (PLP) experience heightened risk of acquiring HIV, which adversely impacts their health and increases the risk for vertical HIV transmission.

Objective: While the Global Database on Blood Safety (GDBS) helps to monitor the status of adequate and safe blood availability, its presence alone does not serve as a solution to existing challenges. The objective of this evaluation was to determine the GDBS usefulness in improving the availability of adequate safe blood and its ability to function as a surveillance system.

Methods: The GDBS was evaluated using methods set out by the Centers for Disease Control and Prevention (CDC) Guidelines for assessing surveillance systems.

Ensuring availability of safe blood products through recruitment of voluntary, nonremunerated, blood donors (VNRDs) and prevention of transfusion-transmissible infections (TTIs), including human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis, is important for public health (1,2). During 2004-2016, the U.S.

The first imported case of Ebola virus disease (Ebola) diagnosed in the United States was confirmed on September 30, 2014; two health care workers who cared for this patient subsequently developed Ebola. Since then, local, state, and federal health officials have continued to prepare for future imported cases, including developing strategies to identify and monitor persons who have had contact with an Ebola patient. This report describes some of the needs of persons who were contacts of Ebola patients in Texas.

Exfoliative erythroderma is a rare presentation of psoriasis in children and adults. We report a 9-year-old girl with exfoliative erythroderma secondary to plaque-type psoriasis who developed hypothalamic-pituitary-adrenal axis suppression resulting from topical treatment with a medium-potency glucocorticoid. This case emphasizes the need for awareness of this potentially life-threatening complication of topical glucocorticoid use, particularly in patients who have significant compromise of barrier function secondary to widespread skin disease.

Background & Aims: Pegylated interferon alfa-ribavirin combination is the standard treatment for chronic hepatitis C, but the mechanisms by which ribavirin enhances the rate of sustained hepatitis C virus (HCV) eradication remain unknown. We aimed to investigate the role of ribavirin in HCV clearance during therapy and to evaluate the consequences of ribavirin discontinuation in patients infected with genotype 1 hepatitis C who cleared HCV RNA at week 24.

Methods: A total of 516 patients were treated with pegylated interferon alfa-2a, 180 microg/wk, plus ribavirin, 800 mg/day.
