U.S. Public Health Service Response to the 2014-2015 Ebola Epidemic in West Africa: A Nursing Perspective.

The 2014-2015 Ebola epidemic in West Africa has been the deadliest Ebola epidemic to date. In response to this deadly epidemic, the U.S. government declared this a top national security priority and members of the Commissioned Corps of the United States Public Health Service were tasked to provide direct patient care to Ebola virus disease patients. Commissioned Corps nurses provided the highest level of care under the most austere conditions. This article discusses the training, ethical dilemmas, and constant risk for potential exposure while working in an Ebola Treatment Unit.

The US Food and Drug Administration review of the safety and effectiveness of nonstandardized allergen extracts.

BACKGROUND: Nonstandardized allergen extracts have been used for a century. Until 1972, these products were regulated by the National Institutes of Health, and products were not required to have an individualized showing of effectiveness. Jurisdiction was then transferred to the US Food and Drug Administration (FDA), which established external review panels to make recommendations regarding safety and effectiveness. Two external panels deliberated, the first from 1974-1979 and the second from 1982-1983. OBJECTIVE: We sought to review external panels' recommendations and assess the safety and effectiveness of nonstandardized allergen extracts, FDA-reviewed available literature, and databases since 1972. METHODS: Currently licensed nonstandardized allergen extracts were reviewed according to extract type. Available data were collected from medical and nonscientific search engines. Nomenclature was ascertained by consulting www.itis.gov or www.atcc.org. The FDA's Adverse Event Reporting System was probed for events associated with extract use. Provisional threshold levels of safety and effectiveness were established, and extracts were sorted according to whether they met the thresholds. RESULTS: In the Adverse Event Reporting System, there were 178 adverse event reports, including 13 deaths, associated with allergen extract use over 23 years. No single group of extracts predominated. Among 1269 allergen extracts reviewed, there were 480 for which use in the diagnosis and treatment of allergic disease were addressed in the literature, 207 for which only diagnostic use was addressed, 565 for which minimal or no supportive literature was identified, and 17 for which potential safety concerns were found. CONCLUSIONS: When used according to professional guidelines, almost all nonstandardized allergen extracts for diagnosis and therapy appear to be safe. Provisional thresholds of effectiveness were met by 54% of extracts reviewed.

Reported infections after human tissue transplantation before and after new Food and Drug Administration (FDA) regulations, United States, 2001 through June, 2010.

Processors distributed about 1.5 million human tissue allografts in the U.S. in 2007. The potential for transmitting infections through allografts concerns clinicians and patients. In 2005, FDA implemented Current Good Tissue Practice (CGTP) rules requiring tissue establishments to report to FDA certain serious infections after allograft transplantations. We describe infection reports following tissue transplants received by FDA from 2005 through June, 2010, and compare reporting before and after implementation of CGTP rules. We identified reports received by FDA from January 2001 through June, 2010, for infections in human tissue recipients, examining the reports by tissue type, organism, time to onset, severity, and reporter characteristics. Among 562 reports, 83 (20.8/year) were received from 2001-2004, before the CGTP rules, 43 in the 2005 transition year, and 436 (96.9/year) from 2006 through June, 2010, after the rules. Tissue processors accounted for 84.2% of reports submitted after the rules, compared to 26.5% previously. Bacterial infections were the most commonly reported organisms before (64.6%) and after (62.2%) the new rules. Afterward, 2.5% (11) of reports described deaths, and 33.7% (147) involved hospitalizations. Before the rules, 13% (11) described deaths, and another 72% involved hospitalizations. Reports received by the FDA quadrupled since 2005, suggesting that CGTP regulations have contributed to increased reporting and improved tissue safety surveillance. However, these data do not confirm that the reported infections were caused by suspect tissues; most reports may represent routine post-surgical infections not actually due to allografts.
