Background: Persistent aminotransferase elevations are common in human immunodeficiency virus (HIV)-infected patients on antiretroviral therapy (ART), including those without hepatitis B or C coinfection, but their clinical significance is unknown.

Methods: HIV-infected adults with aminotransferase levels elevated above the upper limit of normal for ≥6 months while receiving ART, and without chronic viral hepatitis or other known causes of chronic liver disease, underwent a detailed metabolic assessment and liver biopsy.

Results: Sixty-two HIV-infected subjects completed the study.

Optimization of free-breathing whole-heart 3-dimensional cardiac magnetic resonance imaging at 3 tesla to identify coronary vein anatomy and to compare with multidetector computed tomography.

J Comput Assist Tomogr

January 2015

From the *Department of Radiology and Imaging Sciences, National Institutes of Health (NIH) Clinical Center, Bethesda, MD; †Department of Radiology and Radiologic Sciences, Johns Hopkins University School of Medicine, Baltimore, MD; ‡National Institute of Diabetes and Digestive and Kidney Diseases; and §NIH Clinical Center, Bethesda, MD.

Objective: This study optimizes use of 3-T magnetic resonance imaging (MRI) to delineate coronary venous anatomy and compares 3-T MRI with multidetector computed tomography (MDCT) measurements.

Methods: The study population included 37 consecutive subjects (22 men, 19-71 years old). Whole-heart contrast-enhanced MRI images at 3 T were acquired using segmented k-space gradient echo with inversion recovery prepared technique.

Cortical bone mineral density in patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

Clin Endocrinol (Oxf)

March 2015

National Institute of Dental and Craniofacial Research, National Institutes of Health (NIH), Bethesda, MD, USA; National Institutes of Health (NIH) Clinical Center, Bethesda, MD, USA.

Background: Prior studies reveal that bone mineral density (BMD) in congenital adrenal hyperplasia (CAH) is mostly in the osteopaenic range and is associated with lifetime glucocorticoid dose. The forearm, a measure of cortical bone density, has not been evaluated.

Objective: We aimed to evaluate BMD at various sites, including the forearm, and the factors associated with low BMD in CAH patients.

The major surface glycoprotein (Msg), which is the most abundant protein expressed on the cell surface of Pneumocystis organisms, plays an important role in the attachment of this organism to epithelial cells and macrophages. In the present study, we expressed Pneumocystis jirovecii Msg in Saccharomyces cerevisiae, a phylogenetically related organism. Full-length P.

Two-year-old purpose-bred beagles (n = 24) infected with Staphylococcus aureus pneumonia were randomized in a blinded fashion for exchange transfusion with either 7- or 42-day-old canine universal donor blood (80 mL/kg in 4 divided doses). Older blood increased mortality (P = .0005), the arterial alveolar oxygen gradient (24-48 hours after infection; P ≤ .

Article Synopsis
  • The study identifies and characterizes a gene called dmc1, which is involved in meiotic recombination, in three species of Pneumocystis, a fungus that causes pneumonia in immunosuppressed patients.
  • Dmc1 is a single-copy gene that produces a protein showing 61%-70% similarity to yeast Dmc1 proteins and is mainly expressed in the cyst form of Pneumocystis.
  • The analysis of the Pneumocystis jirovecii genome suggests that sexual reproduction may occur in its life cycle, marked by multiple recombination events, despite the organism being primarily haploid.

As health care costs continue to rise, an increasing number of self-insured employers are using financial rewards or penalties to promote healthy behavior and control costs. These incentive programs have triggered a backlash from those concerned that holding employees responsible for their health, particularly through the use of penalties, violates individual liberties and discriminates against the unhealthy. This paper offers an ethical analysis of employee health incentive programs and presents an argument for a set of conditions under which penalties can be used in an ethical and responsible way to contain health care costs and encourage healthy behavior among employees.
