Impact of a Predetermined Day 5 ET vs. a Predetermined Day 6 ET on Clinical Pregnancy Rate After ICSI Treatment
The aim of this prospective multicenter study is to investigate the influence of a predetermined embryo transfer on day 6 compared to a predetermined embryo transfer on day 5. The study population consists of the control group (predetermined embryo transfer on day 5) and the study group (predetermined embryo transfer …
Abbott Cephea Mitral Valve Disease Registry
The objective of this registry is to gather clinical data on symptomatic patients with mitral valve disease, including patients with mitral regurgitation, mitral stenosis, and mixed mitral valve disease. Data collected from this registry are expected to improve our understanding of the impact of correcting symptomatic mitral valve disease on …
In Hospital 24 Hour Observation of Syncope Patients
Syncope is very common and has a broad differential diagnosis. Guidelines on syncope recommend to apply guideline based syncope algorithm (SA) to identify low- / intermediate risk syncope patients and recommend to discharge these patients. The time window when to discharge these patients is not defined in the guidelines. In …
Real-world Clinical Outcomes of NSCLC Patients Receiving Neoadjuvant Immunotherapy
The goal of this observational study is to evaluate the efficacy and long-term clinical outcomes of different neoadjuvant immunotherapies in non-small cell lung cancer (NSCLC) patients using the real-world data. The main questions it aims to answer are: What the best setting for immune checkpoint inhibitors as the neoadjuvant treatment? …
Predictive Performance of a Generative Model for Corneal Tomography After ICL Implantation
To evaluate the efficacy of a corneal tomography Imaging model in predicting postoperative vault based on preoperative corneal topography in Implantable Collamer Lens (ICL) surgery.
The Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) Registry
Retrospective studies indicate that active surveillance for clinically localized, small renal masses (cT1a, <=4cm) is safe. It is our hypothesis that active surveillance is safe and efficacious when compared prospectively to patients undergoing immediate intervention for their small renal mass.
