Dose-volume predictors of cardiac adverse events after high-dose thoracic radiation therapy for lung cancer: a systematic review and meta-analysis.

BMC Cancer

December 2024

Department of Biomedical Sciences, Namur Research Institute for Life Sciences, (NARILIS), Faculty of Medicine, University of Namur, Namur, Belgium.

Background: Lung cancer is a leading cause of cancer mortality and may require high-dose thoracic radiation therapy (RT). However, RT significantly increases the risk of radiation-induced cardiac events, such as pericarditis, cardiomyopathy, and ischemic heart diseases. Despite evidence from clinical trials showing that higher RT doses are associated with poorer survival outcomes due to these cardiac effects, data on dose-volume predictors of such events in lung cancer remain sparse.

Cytochrome P450 phenotyping using the Geneva cocktail improves metabolic capacity prediction in a hospitalized patient population.

Br J Clin Pharmacol

December 2024

Division of Clinical Pharmacology and Toxicology, Department of Anesthesiology, Pharmacology, Intensive Care and Emergency, Geneva University Hospitals (HUG), Geneva, Switzerland.

Aims: Liver cytochromes (CYPs) play an important role in drug metabolism but display a large interindividual variability resulting both from genetic and environmental factors. Most drug dose adjustment guidelines are based on genetics performed in healthy volunteers. However, hospitalized patients are not only more likely to be the target of new prescriptions and drug treatment modifications than healthy volunteers, but will also be more subject to polypharmacy, drug-drug interactions, or to suffer from disease or inflammation affecting CYP activities.

Required minimal protein domain of flower for synaptobrevin2 endocytosis in cytotoxic T cells.

Cell Mol Life Sci

December 2024

Cellular Neurophysiology, Center for Integrative Physiology and Molecular Medicine (CIPMM), Saarland University, 66421, Homburg, Germany.

Flower, a highly conserved protein, crucial for endocytosis and cellular fitness, has been implicated in cytotoxic T lymphocyte (CTL) killing efficiency through its role in cytotoxic granule (CG) endocytosis at the immune synapse (IS). This study explores the molecular cues that govern Flower-mediated CG endocytosis by analyzing uptake of Synaptobrevin2, a protein specific to CG in mouse CTL. Using immunogold electron microscopy and total internal fluorescence microscopy, we found that Flower translocates in a stimulus-dependent manner from small vesicles to the IS, thereby ensuring specificity in CG membrane protein recycling.

Studies on the Stability and Microbial Biotransformation of Five Deschloroketamine Derivatives as Prerequisite for Wastewater-Based Epidemiology Screening.

Drug Test Anal

December 2024

Department of Experimental and Clinical Toxicology and Pharmacology, Institute of Experimental and Clinical Pharmacology and Toxicology, Center for Molecular Signaling (PZMS), Saarland University, Homburg, Germany.

Wastewater (WW)-based epidemiology (WBE) is a powerful tool for screening and surveillance of drugs (of abuse) or new psychoactive substances (NPSs) in larger population. Since the drug market changes frequently, it is crucial for WBE to define screening and surveillance biomarkers considering drug metabolism and (microbial) stability. The aims of the presented work were first to identify metabolites, potentially serving as a WBE biomarker of five deschloroketamine derivatives (DCKDs) in rat feces samples after oral administration in addition to already known urinary metabolites, and second to elucidate the microbial biotransformation and WW stability of five DCKDs and their metabolites detected in urine and feces.

Eur J Anaesthesiol

January 2025

From the Division of Anaesthesiology, Department of Anaesthesiology, Pharmacology, Intensive Care and Emergency Medicine, University Hospitals of Geneva, Geneva, Switzerland (ADSR, MB, RS, GA, ES), Department of Anaesthesia, Northern Lisbon University Hospital Centre, Lisbon, Portugal (ADSR), University Clinic of Anesthesiology and Reanimation, Faculty of Medicine, University of Lisbon, Portugal (ADSR), Division of Clinical Pharmacology and Toxicology, Department of Anaesthesiology, Pharmacology and Intensive Care, University Hospitals of Geneva, Geneva, Switzerland (AN).

Resistance to the effects of rocuronium and other neuromuscular blocking agents (NMBA) has been previously reported, including delayed onset of relaxation, rapid recovery and incomplete paralysis under recommended doses. These conditions have been associated with denervation injury, burns, immobilisation, infections, metabolic disorders, and drug interactions. In this report, we describe the case of a young male without any known pre-disposing factor for NMBA resistance, who failed to attain muscle relaxation with non-depolarising NMBA despite high doses of rocuronium and atracurium during two surgeries for colorectal cancer, several months apart.
