Deep Marginal Elevation and the Periodontal Microenvironment ( DME-PM )

This study aims to evaluate the impact of the dental restorative procedure known as Deep Marginal Elevation (DME) on periodontal health, including gingival and bone status, in patients with deep dental caries. Gingival fluid samples will be collected, and radiographic assessments will be performed to monitor changes in inflammation and bone levels. The findings are expected to provide insights into how DME influences gingival and bone health.

Clinical Trial Recruitment and Retention Strategies for Family Members in the ICU

There is a need to identify strategies that improve the conduct of clinical trials involving family members of intensive care unit (ICU) patients. The purpose of the present study is to evaluate recruitment and retention strategies for clinical trials involving family members of ICU patients. 4 strategies (2 recruitment and 2 retention) will be tested. Investigators will integrate the strategies into three existing studies that involve family members of ICU patients. Participants will be randomized using a 2x2 factorial design. The co-primary outcomes are recruitment percentage (participants enrolled/participants approached) and retention percentage (participants completing follow-up/participants enrolled).

Real-World Clinical Study on the Efficacy of Vibrating Capsule (Vibrabot Capsule) for Chronic Functional Constipation

This study is a multi-center prospective cohort study, which plans to include 300 patients with chronic functional constipation to treat with Vibrabot capsules, and at the same time, include ≥300 patients receiving constipation treatment during the same period. During the study, it is necessary to collect the patients' basic information, baseline constipation status and treatment information, capsule intake during treatment, and concomitant medication. During the treatment phase, patients follow the doctor's advice to receive Vibrabot capsule treatment and maintain stable dietary intake and exercise according to the constipation diagnosis and treatment guidelines.

The treatment effect of the patients is evaluated by assessing the number of occurrences of spontaneous bowel movements (SBM) and complete spontaneous bowel movements (CSBM).

Effect of Vibration Capsule on Different Subtypes of Functional Constipation

This study is a multi-center prospective cohort study, which plans to include 600 patients with chronic functional constipation to treat with Vibrabot capsules and patients will be grouped according to subtypes. During the study, the patients' basic information, baseline constipation status and treatment information, capsule intake during treatment, and concomitant medication will be collected. During the treatment phase, patients follow the doctor's advice to receive Vibrabot capsule treatment and maintain stable dietary intake and exercise according to the constipation diagnosis and treatment guidelines. During the study, patients need to fill in the relevant information during the treatment in the electronic questionnaire in a timely and truthful manner.
