Japanese Lead Extraction Registry
Japanese Lead Extraction (J-LEX) Registry is an observational nationwide registry, performed by Japanese Heart Rhythm Society, collaborated with the National Cerebral and Cardiovascular Center. The acute success rate at discharge and the complications associated with transvenous lead extraction will be collected. J-LEX registry will provide a reliable information on indications, …
Oxygen Extraction-guided Transfusion
In critically ill patients, optimized strategies for red blood cells transfusion (RBCT) are still controversial. Most recent guidelines suggest that clinical practice in ICU setting should follow a restrictive approach to RBCT (i.e., hemoglonim level \< 7.0 g/dL).In our previous study, oxygen extraction ratio (O2ER) has shown good performance as …
Age-related Changes in Retinal Oxygen Extraction in Healthy Subjects
It has been found that several systemic and ocular diseases are associated with impaired retinal oxygen extraction. In the present study, retinal oxygen extraction will be measured in different age groups in order to identify age related changes in otherwise healthy subjects. In addition, the study will explore short-term changes …
Post Extraction Changes Following Ridge Preservation Using Allogenis Dentin Vs Autogenous Partially Demineralized Dentin
Research question: In patients with unrestorable anterior teeth, will the use of allogenic dentin matrix be more effective than autogenous partially demineralized dentine matrix (APDDM) in reducing hard tissue changes after post-extraction ridge preservation in the aesthetic zone? After enrolment, periodontal and radiographic examinations will be conducted, and patients with …
Evaluation of The Stability of Orthodontic Treatment After First Premolar Extraction Using Combined Retention Protocol
The aim of this study is to compare between the stability of anterior and posterior segments in both arches using bonded lingual retainers versus a combined protocol of retention (bonded lingual retainer and vacuum formed retainers). The effect of different treatment changes achieved on the post-treatment stability will be studied …
Effect Of Cavitation In Post-Extractive Socket Healing
In everyday clinical practice, the proper management of the post-extraction socket is crucial in order to enable an optimal healing of the wound and a close post-surgical monitoring is critical to prevent possible complications. After an injury, the cellular reaction starts early, presenting significant changes as soon as 12 to …
Measurement of Total Retinal Blood Flow and Oxygen Extraction in Patients With Diabetes and Healthy Subjects
The prevalence of diabetes and diabetes-associated complications is still increasing. Several major long-term complications of diabetes such as cardiovascular disease, chronic renal failure, diabetic retinopathy and others relate to the damage of blood vessels. Given that the eye provides the unique possibility in the human body to directly visualize blood …
Evaluation of Dentin Graft and I-PRF With and Without Vitamin C for Post-extraction Socket Preservation
The aim of the study is to evaluate radiographic ridge width change following autogenous demineralized dentin graft (ADDG) and i-PRF addition with and without vitamin C (AA) for post extraction socket preservation. The main question is: In patient with non-restorable teeth, does adding vitamin C to dentin graft and i-PRF …
Post Extraction Alterations Following Ridge Preservation In The Esthetic Zone Using Partially Demineralized Autogenous Dentine Graft Versus Xenograft
the aim of this study is to establish if there are clinical, radio-graphical and histomorphometrical differences between using Partially Demineralized Dentin graft versus Xenograft in the esthetic zone. as a clinical application in alveolar bone regeneration procedures related to implant dentistry, including socket preservation, alveolar ridge augmentation, after tooth extraction …
Biomedical Signal Extraction From Symptom Descriptions: An Observational Registry Using the OpenGenome Platform
This registry prospectively collects anonymized free-text symptom descriptions submitted voluntarily by adults through the OpenGenome platform at opengenome.bio. For each submission, the system retrieves real biomedical literature from PubMed and ClinicalTrials.gov in parallel, applies a constrained reasoning model operating under a strict output schema, and returns a structured biological signal …
