The advance of high resolution digital scans of pathology slides allowed development of computer based image analysis algorithms that may help pathologists in IHC stains quantification. While very promising, these methods require further refinement before they are implemented in routine clinical setting. Particularly critical is to evaluate algorithm performance in a setting similar to current clinical practice. In this article, we present a pilot study that evaluates the use of a computerized cell quantification method in the clinical estimation of CD3 positive (CD3+) T cells in follicular lymphoma (FL)...

Background There is a paucity of data on outcomes related to combined heart-lung transplantations (HLTs). Our objective was to identify variables associated with mortality and rejection in HLT. Methods The United Network for Organ Sharing database was reviewed for HLT performed between 1993 and 2008. Long-term survivors (survival > 5 years) were compared with short-term survivors (survival < 5 years). Factors associated with rejection were examined. Risk-adjusted multivariable Cox's proportional hazards regression analysis was performed to examine variables associated with mortality and rejection...

In the past decade, molecular classification of cancer has gained high popularity owing to its high predictive power on clinical outcomes as compared with traditional methods commonly used in clinical practice. In particular, using gene expression profiles, recent studies have successfully identified a number of gene sets for the delineation of cancer subtypes that are associated with distinct prognosis. However, identification of such gene sets remains a laborious task due to the lack of tools with flexibility, integration and ease of use...

INTRODUCTION: The outcomes of patients who fail their kidney transplant and return to dialysis (RTD) has not been investigated in a nationally representative sample. We hypothesized that variations in management of transplant chronic kidney disease stage 5 leading to kidney allograft failure (KAF) and RTD, such as access, nutrition, timing of dialysis, and anemia management predict long-term survival. METHODS: We used an incident cohort of patients from the United States Renal Data System who initiated hemodialysis between January 1, 2003 and December 31, 2008, after KAF...

The complex organization of the mycobacterial cell wall poses unique challenges for the study of its assembly. Although mycobacteria are classified evolutionarily as Gram-positive bacteria, their cell wall architecture more closely resembles that of Gram-negative organisms. They possess not only an inner cytoplasmic membrane, but also a bilayer outer membrane that encloses an aqueous periplasm and includes diverse lipids that are required for the survival and virulence of pathogenic species. Questions surrounding how mycobacterial outer membrane lipids are transported from where they are made in the cytoplasm to where they function at the cell exterior are thus similar, and similarly compelling, to those that have driven the study of Gram-negative outer membrane transport pathways...

Moderate ischemic mitral regurgitation (MR) is often present in patients undergoing coronary artery bypass grafting (CABG). However, the clinical benefit of repairing moderate MR during CABG is unproven. We searched multiple databases to identify original studies comparing isolated CABG versus combined CABG and MR surgery (mitral valve surgery with coronary artery bypass grafting [MVCABG]); survival (either early or midterm) was the primary end point. Risk ratio (RR) or standardize mean difference was selected as the effect estimates; survival was compared by pooling hazard ratios...
