'Real-life' approach to applying PK/PD principles in infectious diseases clinical practice without access to prompt TDM.

Introduction: Infectious disease treatments are transitioning from a one-size-fits-all approach to a more tailored approach. The increasing adoption of therapeutic drug monitoring (TDM) of antimicrobials is a clear example of this trend. Routine antimicrobial TDM in critically ill patients should be mandatory.

Clinical, developmental and serotonemia phenotyping of a sample of 70 Italian patients with Phelan-McDermid Syndrome.

Background: Phelan-McDermid syndrome (PMS) is caused by monoallelic loss or inactivation at the SHANK3 gene, located in human chr 22q13.33, and is often associated with Autism Spectrum Disorder (ASD).

Objectives: To assess the clinical and developmental phenotype in a novel sample of PMS patients, including for the first time auxometric trajectories and serotonin blood levels.

Renal function and its impact on the concentration of ceftazidime-avibactam: A cross-sectional study.

Objective: This study measured the effect of renal function on the plasma concentrations of ceftazidime and avibactam in critically ill patients. We also sought to measure the concentration ratio of ceftazidime to avibactam.

Methods: This was a cohort study at a tertiary referral centre in Italy, on patients treated with continuous infusion of ceftazidime-avibactam (CAZ-AVI) between November 2019 and December 2023.

Employment of pqqE gene as molecular marker for the traceability of Gram negative phosphate solubilizing bacteria associated to plants.

Insoluble phosphorous compounds solubilization by soil bacteria is of great relevance since it puts available the phosphorus to be used by plants. The production of organic acids is the main microbiological mechanism by which insoluble inorganic phosphorus compounds are solubilized. In Gram negative bacteria, gluconic acid is synthesized by the activity of the holoenzyme glucose dehydrogenase-pyrroloquinoline quinine named GDH-PQQ.

Phenotypical Differences at the Physiological and Clinical Level between Two Genetically Closely Related Strains Isolated from Patients.

The occurrence of non-albicans species within the genus poses a major challenge in the clinical setting. , formerly known as , has gained attention due to its potential multidrug resistance, particularly to amphotericin B (AmB). While intrinsic resistance to AmB is rare, secondary resistance may develop during treatment due to phenotypic rearrangement and the reorganization of the cell wall.
