Aminoglycosides in the Intensive Care Unit: What Is New in Population PK Modeling?

Background: Although aminoglycosides are often used as treatment for Gram-negative infections, optimal dosing regimens remain unclear, especially in ICU patients. This is due to a large between- and within-subject variability in the aminoglycoside pharmacokinetics in this population.

Objective: This review provides comprehensive data on the pharmacokinetics of aminoglycosides in patients hospitalized in the ICU by summarizing all published PopPK models in ICU patients for amikacin, gentamicin, and tobramycin.

Chemosensory Anhedonia in Patients With Schizophrenia and Individuals With Schizotypy: A Questionnaire Study.

Anhedonia, the loss or decline of the ability to enjoy pleasure, is an important clinical characteristic of schizophrenia. Schizotypal traits refer to the appearance of subclinical symptoms of schizophrenia across normal people. Still, few studies have investigated chemosensory anhedonia in schizophrenia patients and schizotypy individuals.

The Chemosensory Pleasure Scale: A New Assessment for Measuring Hedonic Smell and Taste Capacities.

Anhedonia, or the inability to experience pleasure, is a key clinical feature of many mental disorders such as depression and schizophrenia. Although various valid measurements of anhedonia and pleasure experience exist, no scales exist that quantify smell and taste pleasure experiences. The Chemosensory Pleasure Scale (CPS) was therefore designed to assess the hedonic capacity for smell and taste pleasure.
