Optimization and Evaluation of the Diagnosis and Treatment System for Diabetic Retinopathy in Type 2 Diabetes Mellitus
This study aims to integrate clinical indicators and features of fundus images, combined with metabolomics, to construct an early warning model for diabetic retinopathy (DR) in type 2 diabetes. By combining clinical indicators with metabolomics, the investigators aim to establish a precise DR typing model based on the age of …
Evolution of Ocular Growth in Myopic Children: A Prospective Cohort Study
Myopia and high myopia are the leading causes of visual impairment and blindness worldwide. The total number of myopic people globally was estimated to be 2.6 billion in 2020, and it could reach 4.8 billion by 2050 unless preventive interventions are implemented. Strategies to slow the progression of myopia, such …
Fulminant Severe CAP - an Observational Study
Severe community-acquired pneumonia (CAP) represents a major cause of hospital mortality. Among severe CAP cases, some exhibit a rapidly progressive evolution, leading to severe ARDS/acute respiratory failure and septic shock within hours to a few days. This type of pneumonia, known as "fulminant pneumonia," is characterized by its rapid onset …
Evaluation of Different Diagnostic Therapeutic Strategies in Patients with Thyroid Pathology
Observational single-center prospective and retrospective, nonpharmacological, spontaneous cohort study.
Clinical Determinants and Adverse Reactions to Tropicamide/Phenylephrine in Hospitalized Patients.
To evaluate the association between clinical determinants and the occurrence of adverse drug reactions in hospitalized patients who received tropicamide/phenylephrine 8 mg/50 mg/mL. An ambispective, interventional, longitudinal study will be conducted to actively identify adverse reactions to tropicamide/phenylephrine 8 mg/50 mg/mL, as well as the clinical determinants that may predispose …
H. Pylori Screen-and-treat Study in a Population of Young Adults
Gastric cancer remains a major challenge to public health on a global scale. H. pylori related cancer burden contributes to the largest proportion of cancer cases attributable to infections in Europe. Considering its absolute burden and persisting disparities, in addition to the substantial prevalence of H. pylori infection worldwide that …
Registry of PHAcoemulsification for Cataract Surgery
Cataracts cause vision loss due to opacities in the lens. Cataract surgery is performed by emulsifying the nucleus of the lens. A phacoemulsifier is the machine used to deliver ultrasonic energy in the eye to fragment the lens and aspirate the debris. In contrast to the large number of cataract …
Optimization of Percutaenous Coronary Intervention With Liberal Use of Post-dilatation
To achieve optimal long-term clinical results after percutaneous coronary intervention (PCI), adequate deployment of stents is essential. Thorough expansion of the stent and full apposition of stent struts against the vessel wall are determining factors for preventing stent thrombosis and restenosis for bare-metal as well as drug-eluting stents (DES). Standard …
Combined Coronary CT Angiography and CT Perfusion in Coronary Artery Disease (CoroFusion)
Coronary computed tomography angiography (CTA) provides high-resolution imaging of coronary artery disease (CAD), revealing stenosis, plaque characteristics, and hemodynamic markers like CT-derived fractional flow reserve (CT-FFR), axial plaque stress (APS), and wall shear stress (WSS). However, CTA alone has limitations in evaluating the functional significance of lesions, especially in cases …
Endocrine, Metabolic, Inflammatory Biomarkers to Identify Highgrade Dysplasia/invasive Carcinoma in Patients with IPMN of the Pancreas
Under the hypotheses that a more accurate patients selection could limit the problem of overtreatment and that benign intraductal papillary mucinous neoplasms (IPMN) have a distinguishable Endocrine/Metabolic/Inflammatory (EMI) profile from those with high-grade disease/invasive carcinoma, this study has three specific aims. The first aim is to evaluate and confirm the …
