Carbapenem-resistant Klebsiella pneumoniae vertebral osteomyelitis in a renal transplant recipient treated with ceftazidime-avibactam.

Ceftazidime-avibactam (CAZ-AVI) is a novel cephalosporin beta lactamase inhibitor combination that has shown activity against carbapenem-resistant Enterobactericeae. Data are limited on its utilization in the treatment of carbapenem-resistant Klebsiella pneumoniae osteomyelitis in solid organ transplant patients. We describe a case report on the use of CAZ-AVI in the treatment of vertebral osteomyelitis in a renal transplant recipient.

In vitro and in vivo activity of single and dual antimicrobial agents against KPC-producing Klebsiella pneumoniae.

Objectives: Options for treatment of infections due to KPC-producing Klebsiella pneumoniae are limited and combination therapy is often recommended. In this report, the in vitro and in vivo activity of potential therapeutic agents and combinations was assessed against four KPC-producing K. pneumoniae isolates.

Optimal method for early detection of cardiac disorders in thalassemia major patients: magnetic resonance imaging or echocardiography?

Background: Heart failure resulting from myocardial iron deposition is the most important cause of death in β-thalassemia major (TM) patients. Cardiac T2*magnetic resonance imaging (MRI), echocardiography, and serum ferritin level serve as diagnostic methods for detecting myocardial iron overload. In this study, we aimed to evaluate the relationship between the above-mentioned methods.

A unified graphical models framework for automated mitosis detection in human embryos.

Time lapse microscopy has emerged as an important modality for studying human embryo development, as mitosis events can provide insight into embryo health and fate. Mitosis detection can happen through tracking of embryonic cells (tracking based), or from low level image features and classifiers (tracking free). Tracking based approaches are challenged by high dimensional search space, weak features, outliers, missing data, multiple deformable targets, and weak motion model.
