A prospective study to evaluate high dose daptomycin pharmacokinetics and pharmacodynamics in spp. infective endocarditis.

Background: Daptomycin pharmacokinetics and pharmacodynamics data relative to higher doses in patients are necessary for clinical practice.

Objectives: A monocentric, prospective study that enrolled patients with a diagnosis of spp. infective endocarditis treated with daptomycin according to clinical practice, to evaluate the pharmacokinetics/pharmacodynamics of different daptomycin daily doses (group A: 8-10 and group B: 11-12 mg/kg).

Antibiotic Stewardship Based on Colonization with Multi-Drug-Resistant Bacteria in Liver Transplantation: A Narrative Review.

In solid organs post-transplant, bacterial infections can complicate the course of recovery with devastating consequences, such as graft loss and death. We provide an expert review on early post-liver transplant bacterial infections, with a focus on infections with multi-drug-resistant organism (MDRO) etiologies. Best practice recommendations are derived from a combination of available evidence and expert consensus.

Bedrock-Dependent Effects of Climate Change on Terricolous Lichens Along Elevational Gradients in the Alps.

In this study, we focused on the bedrock-dependent effects of climate change on terricolous lichen communities along elevational gradients in the Alps. In particular, we contrasted between carbonatic and siliceous bedrock, hypothesizing more favourable conditions on siliceous than on carbonatic bedrock, where dryer conditions may exacerbate the effects of climate change. To test this hypothesis, we compared terricolous lichen diversity patterns between the two bedrock types in terms of (1) species richness, (2) beta-diversity, (3) proportion of cryophilous species, and (4) functional diversity, also testing the effect of the elevational gradient as a proxy for expected climate warming.

Clinical impact of TP53 functional mutations in patients with metastatic colorectal cancer treated with bevacizumab and chemotherapy.

Background: Clinical and experimental studies indicate that the tumor protein p53 (TP53) gene loss of function due to missense mutations (MMs) may confer sensitivity to anti-angiogenics. This effect seems to be linked to cross-talk mechanisms among TP53, vascular endothelial growth factor (VEGF), and VEGF receptors. We investigated whether specific TP53 MMs are associated with clinical outcomes of patients with metastatic colorectal cancer (mCRC) treated with first-line chemotherapy plus Bevacizumab.
