Outcomes and Risk Factors Associated with Clostridium difficile Diarrhea in Hospitalized Adult Patients.

Background. The epidemiology of Clostridium difficile infection has changed over time. Therefore, it is essential to monitor the characteristics of patients at risk of infection and factors associated with poor prognosis.

PCR as a screening test for invasive aspergillosis in haematological patients: a pilot study.

Invasive aspergillosis is a leading cause of morbidity and mortality in immunocompromised patients, particularly in individuals with haematological malignancy and in haematopoietic stem cell transplant recipients. Nowadays, the galactomannan (GM) assay has been widely used as an indication of invasive aspergillosis, even though the test is known to generate false-positive results. The aim of this study was to compare the performance of GM and real-time PCR (qPCR) to detected Aspergillus in blood samples obtained from high-risk haematological patients.
