Researchers are evaluating a new 10-minute cardiovascular magnetic resonance CMR imaging protocol designed to improve current CMR procedures for patients with various heart conditions, including coronary artery disease, cardiomyopathies, and other cardiac diseases. The study aims to develop a standardized, contrast-free imaging method that can be applied to about 70% of cardiac patients. The goal is to assess whether this shorter protocol enhances diagnostic decision-making and reduces healthcare costs. The study involves two groups healthy volunteers over 18 years old without significant cardiovascular or respiratory conditions, and patients over 18 years who require a clinically indicated CMR exam. The new protocol focuses on heart function and tissue characterization without using contrast agents. Researchers will compare the new 10-minute protocol to standard CMR imaging, evaluating its clinical feasibility, performance, and cost-effectiveness in different patient populations. Participants will undergo CMR scans using both the new and standard protocols. Researchers will monitor diagnostic results, scan completion rates, scan sequence times, adverse events, and cost differences between methods. Various heart tissue measurements and reproducibility between different readers and scanners will also be assessed. The study spans from 2019 to 2025, with ongoing safety monitoring during imaging sequences and a focus on improving the efficiency and quality of cardiac imaging.

The GENESIS clinical study aims to map HLA genetic variation in the Greek population and evaluate possible correlations with selected underlying diseases. It is a multicenter, prospective, non-interventional clinical study targeting 12,000 subjects over an anticipated duration of 36 months, with the goal of creating a pilot HLA map for medical research and possible clinical applications. Each subject will complete one visit at a participating site and provide demographic information, including date of birth, gender, race, ancestry, height, and weight, as well as information about smoking or vaping, alcohol consumption, arterial blood pressure, diagnosed diseases, and current treatments. Recent clinical laboratory results from up to 12 months before sample collection may also be collected when available, including blood count, metabolic, liver enzyme, and biochemical parameters. Two buccal swabs will be collected from each subject for DNA extraction and HLA genotyping analysis. Selected DNA samples will also undergo low-pass whole genome sequencing to further investigate associations between the HLA region and autoimmune diseases. After the analysis is completed, an individualized ancestry report will be securely available to study subjects if they elect to access it.

Researchers are developing a multicenter registry to collect and share data on pediatric patients who have undergone deep brain stimulation DBS for movement disorders such as dystonia, epilepsy, Tourette syndrome, and mood disorders. The study aims to improve understanding of DBS safety and effectiveness in children, as current data are limited and individual centers often have too few cases for strong research. This registry will support large-scale analyses and help refine DBS as a treatment option for hyperkinetic movement disorders in the pediatric population. The study involves gathering both retrospective and prospective clinical data from multiple pediatric centers. The registry will collect information on surgical techniques, patient outcomes, implant sites, and long-term effects of DBS. This collaborative data-sharing approach enables comprehensive evaluation of which patients benefit most from DBS and how it impacts their quality of life over time. Participants include children aged 0 to 18 years who have already received or are scheduled to receive DBS for neurological movement disorders. Data will be collected over five years to monitor safety, efficacy, and quality of life outcomes. The study does not involve treatment administration but focuses on gathering and analyzing clinical information. Parental or legal guardian consent is required for prospective participation.

This research aims to evaluate postoperative respiratory complications PORC in children with obstructive sleep apnea OSA who undergo adenotonsillectomy. It combines data from two centers University Hospital Antwerp and Heim Pal National Pediatric Institute in Hungary. The study examines how common these complications are and whether they vary according to different health conditions such as obesity, craniofacial malformations, Down syndrome, or neurological disorders that affect airway muscle tone. Data come from a retrospective analysis of electronic health records originally collected in two prospective studies. These records include children who had adenotonsillectomy for OSA, with postoperative care following a set protocol. The study looks at factors like the obstructive apnea-hypopnea index, oxygen levels during sleep studies, age at surgery, and presence of other health conditions to understand their relationship with PORC and to help develop a management plan. Participants information was collected without needing additional consent because it uses existing anonymized data. Researchers assess the prevalence of PORC within 24 hours after surgery and analyze how different factors affect this risk. This study does not involve new treatments but reviews existing data to improve postoperative care. The study includes children aged 1 to 18 years who had adenotonsillectomy for OSA, with follow-up limited to the immediate postoperative period.
