Angioplasty With Shockwave IVL Catheter System in Femoropopliteal Lesions
There is a lack of prospective observational studies of shockwave balloons in the treatment of moderate-to-severe calcification of the femoral popliteal artery at the international level. Therefore, in this study, we wish to set up a real-world study of shockwave balloon in the treatment of moderate-to-severe calcification to investigate the …
Diagnosis of Myocardial Ischemia With MCG Using SPECT as a Reference Standard
This is a prospective clinical study aiming to investigate the efficacy of Magnetocardiography (MCG) in detecting myocardial ischemia in patients of a suspected non-ST-elevation-acute coronary syndrome (NSTE-ACS) by using Single photon emission computed tomography (SPECT) as the gold standard for determining the presence and severity of myocardial ischemia.
Clinical Study of 18F-Labeled FAPI-04 in PET Imaging of Breast Cancer
This study aims to evaluate the diagnostic accuracy (sensitivity, specificity, positive/negative predictive value, and overall accuracy) of 18F-FAPI-04 PET imaging in breast cancer for detecting fibroblast activation protein (FAP)-rich lesions. Additionally, the study will longitudinally monitor dynamic changes in FAP expression levels and tumor size during therapy, including chemotherapy, targeted …
Evaluation of Blood and Cardiac Protein O-GlcNAcylation Levels in Cardiac Surgery in Children
Cardiac surgery requires the use of extracorporeal circulation (ECC). Age-related differences in inflammatory response, the greater susceptibility of immature organ systems to injury and the larger ratio of extracorporeal circuitry to patient size make younger and smaller patients more vulnerable to organ injury. The main problem associated with ECC in …
Efficacy of Isatuximab-based Regimens in Relapsed/Refractory Multiple Myeloma With 1q21+
This is a non-interventional, national, multicentre retrospective and prospective observational study aiming at assessing the efficacy of isatuximab-based regimens in RRMM patients with 1q21+ in a real-life setting. Due to the limited information as to isatuximab's impact in real-world settings and that MM is a rare cancer, patients will be …
Observational Study of Platelet Dysfunction Assessed by Thromboelastography in Cardiovascular Surgery (DISPLATEG)
Perioperative bleeding requiring blood transfusion is common during cardiovascular surgery, especially in procedures requiring cardiopulmonary bypass. Adenosine diphosphate (ADP) plays a fundamental role in platelet function. Several studies have shown that some patients not receiving antiplatelet therapy undergoing cardiovascular surgery have decreased platelet ADP receptor activity; the prevalence of this …
Bleeding Events Before vs After Lowering Departmental Platelet Transfusion Trigger
Central venous catheters are essential when administering treatment for hematological conditions. Many patients have a decreased platelet count which increases the risk for bleeding complications. Baarle et al. recently published a randomized controlled study where withholding prophylactic platelet transfusions before CVC placement in patients with a platelet count of 10,000 …
The α-gal Syndrome - Investigating Immune Reactions to Tick Bites Leading to Inflammation and Allergic Sensitization
The goal of this clinical trial is to follow immune response and antibody build-up in individuals bitten by a tick. Participants are invited to enroll within 48 hours after the tick removal and donate some blood. The tick is also collected and analysed. Researchers will then try to answer the …
Negative Emotionality and Epigenetics During Puberty
Pubertal transition leads to enduring neuroendocrine changes along with changes in the epigenome. The prevalence of psychiatric disorders significantly increases in females compared to males after puberty. There is likely to be an interaction between epigenetics, hormones and neurophysiological processes during puberty, leading to the increased prevalence of mental disorders …
Dual-energy SPEctral CT to Evaluate Response to First-line Therapies in Patients With Metastatic Clear Cell REnal Cancer
To evaluate the utility of dual-energy spectral computed tomography (CT) scan in monitoring treatment in patients with metastatic clear cell carcinoma of the kidney. In particular, to analyze the use of spectral CT in patients who are candidates to receive first-line treatment based on combinations of immunotherapy and molecularly targeted …
