Respiratory Oscillometry for the Prediction of Bronchopulmonary Dysplasia
The goal of this observational study is to learn about the correlation between respiratory system reactance, as assessed by respiratory oscillometry, and respiratory outcomes in preterm infants born before 32 weeks of gestation. The main question it aims to answer is if the reactance z-score at 7 postnatal days adds …
The Comparison Between Computed Tomography and Colonoscope in Detecting Colorectal Tumors in Patients With FIT+
Colonoscopy is the mainstay modality of choice in colorectal cancer screening worldwide. However, the rate of colonoscopy for colorectal cancer screening is very low (approximately 5-10%) because of the limited local medical resources (such as endoscopists and regional endoscope). This observational diagnostic test study aims to compare the diagnostic yield …
Analysis of Individual Activity at the Time of Aortic Rupture in Patients With Abdominal Aortic Aneurysms
It is currently unclear what activities aneurysms are involved in at the time of rupture. The aim of the study is to determine the activity performed at the time of aneurysm rupture.
Observational Study to Assess Endpoint Operational Feasibility & Measurement Properties in Patients with Retinal Degeneration
The Vision Research and Assessment Institute (VRAI) was established with the purpose of serving as a testing facility for efficacy endpoints for patients with Low Vision. The mission of the VRAI is to enable the highest quality, standardized efficacy testing of patients with visual impairment. The VRAI facilitates the development …
Multicenter Cohort Study of ESD and Chemo-radiotherapy for High-risk Early-stage Esophageal Cancer
This multicenter, prospective observational cohort study has the potential to optimize individualized chemoradiotherapy regimen for early-stage esophageal cancer patients who have received endoscopic submucosal dissection.
Relationship Between Acute Phase Markers and Post-operative Pain in Laparoscopic Cholecystectomy: An Observational Study
Many patients undergoing laparoscopic cholecystectomy are prone to developing acute and chronic post-operative pain. The aim of the study is to show a possible correlation between pain and acute phase proteins in order to: predict the severity of pain; select most suitable pain relief therapy for the patient.
Explore New Magnetic Resonance Technology in Assessment of Renal Dysfunction
Currently, renal biopsy is the gold standard for evaluating renal pathology and renal fibrosis, but it is invasive and carries the risk of serious complications; and the sampled tissue is only a small part of the kidney, which is prone to sampling bias. The lack of reliable, comprehensive test results …
Analysis of PD-L1, TMB, MSI and ctDNA Dynamics to Predict and Monitor Response to Immunotherapy in Metastatic Cancer.
This is an observational clinical trial, aiming to investigate whether the ctDNA dynamics could predict early response to ICIs in patients with advanced-stage cancer. Moreover, conventional tumor markers PD-L1, TMB and MSI are to be investigated for their combined prognostic values in ICI treatment.
Effect of Non-chirurgical Periodontal Treatment on the Immune System From a Gender Perspective
The goal of this observational study is to evaluate non-surgical periodontal treatment in women and men with periodontitis with and without obesity. The main questions it aims to answer are: If non-surgical periodontal treatment of patients with chronic periodontitis can modulate the innate and adaptive immune response taking into account …
Role of Antifungal Prophylaxis in Elderly Patients With Acute Myeloid Leukemia During Consolidation Therapy
In previous retrospective study (SEIFEM 2016 study) the investigators evaluated the incidence of proven/probable invasive aspergillosis (IA) and the role of mold active primary antifungal prophylaxis (PAP) in a "real life" setting of acute myeloid leukemia (AML )patients receiving intensive consolidation therapy. All cases of proven/probable IA, observed during consolidation …
