A Study of Guselkumab Therapy in Participants With Moderately to Severely Active Ulcerative Colitis

ASTRO
Start date: September 13, 2022

NCT ID: NCT05501873 Active, not recruiting - Atrial Fibrillation Clinical Trials

Real World Data Collection in Subjects Treated With the FARAPULSE Pulsed Field Ablation System

FARADISE
Start date: March 24, 2023
Phase:
Study type: Observational [Patient Registry]

The goal of any novel design or therapeutic strategy to treat atrial fibrillation is to restore normal sinus rhythm and to reduce or eliminate the symptoms due to rapid atrial response. Boston Scientific has developed the FARAPULSE™ Pulsed Field Ablation therapy that uses irreversible electroporation to induce cell death. This Registry is intended to obtain purely observational and prospective real world data and to provide continued evidence on the safety and effectiveness when the FARAPULSE™ pulsed field ablation System is used per hospitals' standard of care.

NCT ID: NCT05418322 Active, not recruiting - Adult Clinical Trials

The Effects of Oral Hygiene Interventions Prior Orthodontic Treatment in Adults

Start date: May 10, 2022
Phase: N/A
Study type: Interventional

Orthodontic treatment has many recognized benefits such as enhancing esthetics and improving self-esteem in patients. However, like any other dental treatments, a successful orthodontic treatment requires patient cooperation, especially oral hygiene compliance. Dental plaque that builds upon the orthodontic brackets in a poor oral environment consists of pathogenic biofilms that can lead to undesirable complications such as white spot lesions, gingivitis, and periodontal breakdown. Poor oral hygiene during orthodontic treatment often results in poor treatment quality and prolonged treatment duration. Fixed appliances increase the retention areas for plaque accumulation and this often makes maintaining good oral hygiene a challenge for the patients. Therefore, effective oral hygiene interventions are key in improving patients' knowledge, influencing good oral hygiene behaviors and ensuring patients can exercise good practices daily at home. Oral hygiene education given to prospective orthodontic patients will allow them to understand their role and responsibilities in maintaining good oral care during treatment. This will help instill lasting good oral hygiene habits that can be maintained during the fixed appliance stage of treatment, thus reducing possible future treatment complications. In this study, the investigators evaluate the effects of verbal and video-assisted oral hygiene interventions on patients' oral hygiene prior to orthodontic treatment.
