Accountable models of care delivery demand that health care provider organizations be able to exchange clinical data about the patient. The "Meaningful Use" program is helping to advance health information exchange by requiring physicians and hospitals to exchange clinical data about patients in order to qualify for incentive payments for electronic health records. Early studies demonstrate that the ability to exchange clinical data among provider organizations has the potential to improve clinical care. However, as with any technology, there is a risk of unintended consequences from health information exchange. This manuscript outlines seven aspects of health information exchange that, if not managed properly, may lead to unintended consequences. These categories are: (1) the desire for complete, accurate and timely data for decision making, (2) data management and presentation, (3) assuring routine use of health information exchange, (4) consideration of patient perceptions and concerns, (5) reputational and financial concerns, (6) technical issues and (7) administrative aspects of health information exchange. Education about the capabilities and limitations of health information exchange, along with checklists to support proper implementation and assure that systems are being used as planned, can mitigate risks and help to realize the promise of this powerful technology. © 2012 Society of General Internal Medicine.

Objective: To review available data describing the epidemiology, outcomes, prevention, and treatment of influenza virus in the solid organ transplant population and to evaluate the strengths and limitations of the current literature, with a focus on literature reviewing annual influenza strains and the recent pandemic novel influenza A/H1N1 strain. DATA SOURCES: A systematic literature search (July 1980-June 2011) was performed via PubMed using the following key words: influenza, human; influenza; novel influenza A H1/N1; transplantation; solid organ transplantation; kidney transplant; renal transplant; lung transplant; heart transplant; and liver transplant. Study Selection and Data Extraction: Papers were excluded if they were not written in English or were animal studies or in vitro studies. Data from fully published studies and recent reports from international conferences were included. Data Synthesis: The influenza virus presents a constant challenge to immunocompromised patients and their health care providers. The annual influenza strain introduces a highly infectious and pathogenic risk to solid organ transplant recipients. In 2009, the World Health Organization declared a pandemic as a result of a novel influenza A/H1N1 strain. The pandemic introduced an additional viral threat to solid organ transplant patients at increased risk for infectious complications. The mainstay for prevention of influenza infection in all at-risk populations is appropriate vaccination. Antiviral therapies against influenza for chemoprophylaxis and treatment of infection are available; however, dosing strategies in the solid organ transplant population are not well defined. Conclusions: The solid organ transplant population is at an increased risk of severe complications from influenza infection. Identifying risks, preventing illness, and appropriately treating active infection is essential in this patient population.

Carbapenems are increasingly needed to treat infections caused by drug-resistant gram-negative bacilli (GNB), but carbapenem resistance is increasing. We evaluated the activity of doripenem by broth microdilution against 96 extensively drug-resistant (XDR) Acinetobacter baumannii and Klebsiella pneumoniae isolates from patients with hospital-associated infections. All isolates were non-susceptible to doripenem, but ≥1 doripenem combination demonstrated synergy (fractional inhibitory concentration index: ≤0.5 for 2 agents, ≤0.75 for 3 agents) against 7 (15%) A. baumannii and 23 (48%) K. pneumoniae isolates; doripenem with rifampin and/or polymyxin B were most active. As doripenem has unique potential for use in prolonged infusions, suggested pharmacodynamic (PD) breakpoints range from 2-8 μg/mL; synergistic activity was found for higher proportions of XDR-GNB at higher PD breakpoints with doripenem with amikacin or with rifampin. The clinical utility of these observations requires further study, as treatment options for XDR-GNB infections are limited. © 2013 Elsevier Inc.

In the first and second trimesters, chemicals produced by the fetoplacental unit are measured to assess risks of fetal abnormalities. Consistent associations between levels of these proteins in such pregnancies enable these biomarkers to be used to calculate risk for Down syndrome and other chromosomal abnormalities in individual pregnancies. Special consideration may be required when assessing risk in multiple pregnancies and pregnancies achieved with infertility therapy. © 2014, Lippincott Williams & Wilkins.

The establishment of the coronary circulation is one of the final critical steps during heart development. Despite decades of research, our understanding of how the coronary vasculature develops and connects to the aorta remains limited. This review serves two specific purposes: it addresses recent advances in understanding the origin of the coronary endothelium, and it then focuses on the last crucial step of coronary vasculature development, the connection of the coronary plexus to the aorta. The chick and quail animal models have yielded most of the information for how these connections form, starting with a fine network of vessels that penetrate the aorta and coalesce to form two distinct ostia. Studies in mouse and rat confirm that at least some of these steps are conserved in mammals, but gaps still exist in our understanding of mammalian coronary ostia formation. The signaling cues necessary to guide the coronary plexus to the aorta are also incompletely understood. Hypoxia-inducible transcription factor-1 and its downstream targets are among the few identified genes that promote the formation of the coronary stems. Together, this review summarizes our current knowledge of coronary vascular formation and highlights the significant gaps that remain. In addition, it highlights some of the coronary artery anomalies known to affect human health, demonstrating that even seemingly subtle defects arising from incorrect coronary plexus formation can result in significant health crises. © 2014 Elsevier Inc.
