Article Abstract
Extracellular vesicles (EVs) have emerged as new drug delivery systems as well as a regenerative cell-free effectors going beyond academic research to reach industrial research and development (R&D). Many proof-of-concept studies are now published describing the delivery of drugs, nanoparticles or biologics among which nucleic acids, proteins, viruses, etc. Their main interests rely on their intrinsic biocompatibility, targeting capabilities and biological activities. The possibility of loading EVs with exogenous therapeutic drug/nanoparticles or imaging tracers opens up the perspectives to extend EV therapeutic properties and enable EV tracking. Clinical translation is still hampered by the difficulty to produce and load EVs with large scale, efficient and cGMP methods. In this review, we critically discuss important notions related to EV engineering and the methods available with a particular focus on technologies fitted for clinical translation. Besides, we provide a tentative data reporting frame in order to support comparability and standardization in the field.

Myocardial injury constitutes a life-threatening complication of sepsis, driven by synergistic oxidative-inflammatory pathology involving dysregulated production of reactive oxygen species (ROS), reactive nitrogen species (RNS), and proinflammatory cytokines. This pathophysiological cascade remarkably elevates morbidity and mortality rates in septic patients, emerging as a key contributor to poor clinical outcomes. Despite its clinical significance, no clinically validated therapeutics currently exist for managing septic cardiomyopathy.

Background: Pulmonary hypertension (PH) is a systemic illness with increasingly subtle disease manifestations including sleep disruption. Patients with PH are at increased risk for disturbances in circadian biology, although to date there is no data on "morningness" or "eveningness" in pulmonary vascular disease.
Research Questions: Our group studied circadian rhythms in PH patients based upon chronotype analysis, to explore whether there is a link between circadian parameters and physiologic risk-stratifying factors to inform novel treatment strategies in patients with PH?
Study Design And Methods: We serially recruited participants from July 2022 to March 2024, administering in clinic the Munich Chronotype Questionnaire (MCTQ).

Purpose: Tumor comprehensive genomic profiling (CGP) may detect potential germline pathogenic/likely pathogenic (P/LP) alterations as secondary findings. We analyzed the frequency of potentially germline variants and large rearrangements (LRs) in the RATIONAL study, an Italian multicenter, observational clinical trial that collects next-generation sequencing-based tumor profiling data, and evaluated how these findings were managed by the enrolling centers.
Patients And Methods: Patients prospectively enrolled in the pathway-B of the RATIONAL study and undergoing CGP with the FoundationOne CDx assays were included in the analysis.

The hallmarks of mechanosensitive ion channels have been observed for half a century in various cell lines, although their mechanisms and molecular identities remained unknown until recently. Identification of the bona fide mammalian mechanosensory Piezo channels resulted in an explosion of research exploring the translation of mechanical cues into biochemical signals and dynamic cell morphology responses. One of the Piezo isoforms - Piezo1 - is integral in the erythrocyte (red blood cell; RBC) membrane.
