A Study to Assess the Long-Term Safety of Ustekinumab Versus Other Biologics in Patients With Crohn's Disease and Ulcerative Colitis
The purpose of this study is to estimate and compare the incidence of overall malignancy, serious infection, and opportunistic infections between new users of ustekinumab and new users of other biologic therapies among adult participants with Crohn's disease (CD) or ulcerative colitis (UC).
A Natural History Study Seeks to Understand the Clinical, Genomic, Pharmacological, Laboratory, and Dietary Determinates of Pyrimidine and Purine Metabolism Disorders
Background Pyrimidine and purine metabolism disorders (DPPMs) affect how the body metabolizes chemicals called pyrimidines and purines. DPPMs can cause dysfunctions throughout the body, especially in the brain, blood, kidneys, and immune system. People with DPPMs might have no symptoms, mild symptoms, or they may have severe, chronic symptoms, that …
Contribution of Point of Care Ultrasound by the Emergency Physician to Rule Out the Small Bowel Obstruction: a Diagnostic, Multicenter Study
Small Bowel Obstruction (SBO) is a frequent pathology in the emergency department (ED). Diagnosis is currently based on abdominal CT scan (CT). Moreover, CT is warranted to determine the therapeutic strategy in patients with SBO which could include medical treatment; surgical intervention or both. However, CT is associated with drawbacks …
TIRANA-ACS: A Prospective Registry Study for the Targeted Investigation of Residual Inflammation After Non-ST/ ST Elevation Acute Coronary Syndrome
This prospective observational study aims to evaluate the prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) as a predictor of mortality in patients following an episode of Acute Coronary Syndrome (ACS). Despite advancements in interventional cardiology and medical therapy, mortality remains significant in post-ACS patients, and early risk stratification is essential …
Development and Prospective Validation of a Multimodal Fusion Artificial Intelligence Model for Predicting the Efficacy of Neoadjuvant Treatment of Bladder Cancer
This study is a multi-center observational study without interventions, including the construction of an AI diagnostic model and retrospective testing of a multi-center cohort. The study participants are bladder cancer patients who have undergone imaging examinations, been pathologically diagnosed, and received neoadjuvant treatment, with complete clinical and pathological data. The …
A Multicenter Study in Bronchoscopy Combining Stimulated Raman Histology With Artificial Intelligence for Rapid Lung Cancer Detection - The ON-SITE Study
The ON-SITE study represents a prospective, observational study focused on the training/tuning and pivotal validation of deep learning algorithms that detect cell/tissue morphology suspicious for cancer in biopsies of peripheral lung nodules/masses and mediastinal/hilar lymph nodes imaged with the NIO Laser Imaging System in the procedure room without requiring traditional …
CHOLE-POSSUM PRO Validation for Prediction of Mortality After Cholecystectomy for Acute Calculous Cholecystitis: Protocol for a Prospective Multicenter Observational Study
CHOLE-POSSUM PRO is a prospective multicenter observational study on patients with ACC candidate to EC. The rationale of the study is to validate the CHOLE-POSSUM PRO SCORE for 30-day mortality in this population.
A Real-World Study on Ultrasound-Based Screening and Integrated Therapeutic Strategies for Patients With Concomitant Coronary and Cervicocephalic Artery Stenosis
This prospective observational cohort study aims to investigate the prevalence and clinical significance of head and neck arterial stenosis in patients with coronary artery disease (CAD) undergoing or scheduled for percutaneous coronary intervention (PCI). Using Doppler ultrasound as the primary screening tool, the study will assess the degree of stenosis …
Introduction of Arpraziquantel Treatment for Schistosomiasis Control in Preschool-aged Children in Endemic Areas: A Small-scale Public Health Intervention Study
The proposed small-scale pilot studies are public health intervention studies implemented through established routine programs and services in the frame of the mass drug administration (MDA) campaigns in Côte d'Ivoire, Kenya and Uganda. In each country two most promising health intervention platforms were selected for pilot distribution of arpraziquantel 150mg …
Validation of a Rapid Screening Tool for Anxiety-depressive Disorders in Children, Adolescents and Young Adults Treated in Oncology. Multicenter Study.
In France today, it is estimated that one in every 850 people aged between 20 and 45 is a childhood cancer survivor (CCS), equivalent to around 40,000 to 50,000 people. Some descriptive studies have established that the diagnosis and treatment of cancer can affect psychological health. A French study published …
