NCT07291609
The CCS-plastics is an investigator-initiated, prospective, multicenter study of patients undergoing coronary CT angiography (CCTA) for suspected or known chronic coronary syndromes (CCS) referred to invasive coronary angiography for clinical indication. Patients identified as eligible for the protocol will be asked for written consent to participate in the study. The patients' dossiers will be uploaded and transmitted to the core laboratory for analysis. The routine management of the CCS patients will not be affected and all patients will be managed according to current standards. Invasive coronary angiography and coronary blood samples will be performed following the current standards, guidelines, and indications. During invasive coronary angiography, coronary blood samples will be collected per standard of care and sent to a centralized, specialized core laboratory for MNPs and biomarkers analysis. The central core lab for MNPs analyses will be the University of Campania Luigi Vanvitelli, Naples, Italy. The identification, quantification (concentration, mcg/ml), and typing of plastic particles will be performed in each tube for each patient, using pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) and laser direct infrared (LDIR) spectroscopy. The CCTA will be centrally analyzed by Centro Cardiologico Monzino to evaluate qualitative and quantitative plaque features. Patients will be followed clinically at 1 and 3 years per standard of care.

This request pertains to a series of related projects on a common theme. Specifically, this set of projects aims to analyze the impact of new alternatives in materials and structures of artificial turf on athlete performance and perception, within the context of the elimination of microplastics as per Commission Regulation (EU) 2023/2055 of September 25, 2023. Third-generation sports artificial turf is notable for including performance infill (granules) that provide the necessary functionality and safety for sports practice. The vast majority of fields worldwide use materials that do not comply with the new European regulation, which has granted an eight-year moratorium. Therefore, there is little time to find new alternatives. The challenge lies not only in developing new structural solutions but also in understanding their impact on athletes. This issue is of high severity, as these sports facilities are the largest in terms of space and host the highest number of Physical Activity and Sports practitioners in Europe (mainly Football, Rugby, Hockey, and Padel). For this reason, over the past year, the IGOID Group has requested various projects to cover all the necessary phases and nuances to address this issue. The activities included in these projects are divided into two phases: Phase 1: Evaluation of Sports Surfaces in the Laboratory (durability and surface-player and surface-ball interaction). Tests will be conducted on artificial turf samples constructed with SBR rubber (the main material to be replaced under the EU regulation), natural-origin infills, polymeric infills larger than 5 mm, and other infills. Initially, a market analysis and classification will be carried out, followed by laboratory tests. Across all projects, a minimum of 30 alternatives are expected to be analyzed. Phase 2: Field Study. Tests will be conducted on a sample of athletes on constructed surfaces representing the different alternatives evaluated in Phase 1. Performance tests and a battery of assessments will be carried out to understand athlete perception. A sample of 30 athletes will be randomly divided into groups to perform different repetitions of the test batteries, covering a minimum of six different sports facilities.

Microplastic rate is increasing ib athmosphere. They can be found in lung, kidney, heart, even placenta. Otitis media with effusion (OME) is a clinical condition that is ver common in children. Biofilms are blamed in the pathogenesis of OME. Microplastics can include biofilms. Importance of microplastics for potential pathogens and their toxicity aspects should be enlighted with studies. This study aims to investigate presency of microplastics in middle ear fluid of patients with OME.
