Since 1981 we monitored all the bacteria strains isolated from patients bearing a surgical infection and hospitalized in our department. We also tested the susceptibility of the isolated strains to different antibiotics. The observed results at three different intervals (1981, 1984, 1987-1988) reveal an increase in Gram+strains. Among the tested antibiotics Imipenem and Amikacin showed the highest antibacterial activity in recent years (1987-1988).

Vaginal reconstruction is necessary for various congenital and acquired conditions, including vaginal aplasia, trauma, tumors, and gender incongruency. Current surgical and non-surgical treatments often result in significant complications. Decellularized vaginal matrices (DVMs) from human tissue offer a promising alternative, but require effective sterilization to ensure safety and functionality.

Cardiac implantable electronic devices infections (CIEDI) are associated with poor survival despite the improvement in transvenous lead extraction (TLE). Aetiology and systemic involvement are driving factors of clinical outcomes. The aim of this study was to explore their contribute on overall mortality.

Although respiratory symptoms are the most prevalent disease manifestation of infection by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), nearly 20% of hospitalized patients are at risk for thromboembolic events. This prothrombotic state is considered a key factor in the increased risk of stroke, which is observed clinically during both acute infection and long after symptoms clear. Here, we develop a model of SARS-CoV-2 infection using human-induced pluripotent stem cell-derived endothelial cells (ECs), pericytes (PCs), and smooth muscle cells (SMCs) to recapitulate the vascular pathology associated with SARS-CoV-2 exposure.

Congenital thrombotic thrombocytopenic purpura (cTTP), which is associated with mutations in the gene for a disintegrin and metalloproteinase with a thrombospondin type 1 motif member 13 (ADAMTS13), is a chronic and lifelong disease. The clinical course is variable. Regularly using ADAMTS13-containing products such as fresh frozen plasma (FFP) for long-term prophylaxis is the most important treatment to prevent thrombotic microangiopathy (TMA) episodes.

Background: Early posttransplant cytomegalovirus (CMV) infections in CMV seronegative solid organ transplant recipients (SOTR) with CMV seronegative donors (D-/R-) are often attributed transfusion-transmitted CMV. The prevalence of false-negative donor CMV serology in D-/R- SOTR with early CMV infections has not been explored.
Methods: We determined the frequency and characteristics of CMV DNAemia that occurred within 90 days of transplant among adult SOTR classified as D-/R- who underwent a first SOT at a single center between February 25, 2014 and February 25, 2024.
