Ebola virus disease: What clinicians in the United States need to know

In March 2014 the World Health Organization was notified of an outbreak of Ebola virus disease (EVD) in the forest region of Guinea. Over the subsequent 8 months, this outbreak has become the most devastating Ebola epidemic in history with 21,296 infections and 8,429 deaths. The recent introduction of Ebola into noncontiguous countries including the United States from infected travelers highlights the importance of preparedness of all healthcare providers. Early identification and rapid isolation of patients suspected of being infected with Ebola virus is critical to limiting the spread of this virus. Additionally, enhanced understanding of Ebola case definitions, clinical presentation, treatment and infection control strategies will improve the ability of healthcare providers to safe care for patients with Ebola virus disease

Fecal microbiota transplant for infection in older adults

Background: The objective of this study was to describe the safety of fecal microbiota transplant (FMT) for Clostridium difficile infection (CDI) among older adults. Methods: We performed a case review of all FMT recipients aged 65 or older treated at Emory University Hospital, a tertiary care and referral center for Georgia and surrounding states. Results: CDI resolved in 27 (87%) of 31 respondents, including three individuals who received multiple FMTs. Among four whose CDI was not resolved at follow up, three respondents did well initially before CDI recurred, and one individual never eradicated his CDI despite repeating FMT. During the study, five deaths and eight serious adverse events requiring hospitalization were reported within the study group during the follow-up period. Fecal transplant was not a causative factor in these events. The most common adverse event reported in 4 (13%) of 31 respondents was subjective worsening of arthritis. Conclusion: FMT is a generally safe and effective treatment option for older adults with CDI

CDC Safety Training Course for Ebola Virus Disease Healthcare Workers

Response to sudden epidemic infectious disease emergencies can demand intensive and specialized training, as demonstrated in 2014 when Ebola virus disease (EVD) rapidly spread throughout West Africa. The medical community quickly became overwhelmed because of limited staff, supplies, and Ebola treatment units (ETUs). Because a mechanism to rapidly increase trained healthcare workers was needed, the US Centers for Disease Control and Prevention developed and implemented an introductory EVD safety training course to prepare US healthcare workers to work in West Africa ETUs. The goal was to teach principles and practices of safely providing patient care and was delivered through lectures, small-group breakout sessions, and practical exercises. During September 2014–March 2015, a total of 570 participants were trained during 16 course sessions. This course quickly increased the number of clinicians who could provide care in West Africa ETUs, showing the feasibility of rapidly developing and implementing training in response to a public health emergency

Prognostic Value of Global MR Myocardial Perfusion Imaging in Women With Suspected Myocardial Ischemia and No Obstructive Coronary Disease Results From the NHLBI–Sponsored WISE (Women's Ischemia Syndrome Evaluation) Study

ObjectivesThe purpose of this study was to assess the prognostic value of global magnetic resonance (MR) myocardial perfusion imaging (MPI) in women with suspected myocardial ischemia and no obstructive (stenosis <50%) coronary artery disease (CAD).BackgroundThe prognostic value of global MR-MPI in women without obstructive CAD remains unknown.MethodsWomen (n = 100, mean age 57 ± 11 years, age range 31 to 76 years), with symptoms of myocardial ischemia and with no obstructive CAD, as assessed by coronary angiography, underwent MR-MPI and standard functional assessment. During follow-up (34 ± 16 months), time to first adverse event (death, myocardial infarction, or hospitalization for worsening anginal symptoms) was analyzed using global MPI and left ventricular ejection fraction (EF) data.ResultsAdverse events occurred in 23 (23%) women. Using univariable Cox proportional hazards regression modeling, variables found to be predictive of adverse events were global MR-MPI average uptake slope (p < 0.05), the ratio of MR-MPI peak signal amplitude to uptake slope (p < 0.05), and EF (p < 0.05). Two multivariable Cox models were formed, 1 using variables that were performance site dependent: ratio of MR-MPI peak amplitude to uptake slope together with EF (chi square: 13, p < 0.005); and a model using variables that were performance site independent: MR-MPI slope and EF (chi square: 12, p < 0.005). Each of the 2 multivariable models remained predictive of adverse events after adjustment for age, disease history, and Framingham risk score. For each of the Cox models, patients were categorized as high risk if they were in the upper quartile of the model and as not high risk otherwise. Kaplan-Meier analysis of time to event was performed for high risk versus not high risk for site-dependent (log rank: 15.2, p < 0.001) and site-independent (log rank: 13.0, p < 001) models.ConclusionsAmong women with suspected myocardial ischemia and no obstructive CAD, MR-MPI–determined global measurements of normalized uptake slope and peak signal uptake, together with global functional assessment of EF, appear to predict prognosis
