NCT05190614
To evaluate a star-shaped incision technique to thick-gingiva and thingingiva patients treated with implant-supported fixed prosthesis. The star-shaped incision would be an effective and simple method to reconstruct gingival papillae and avoid the gingival recession in thick-gingiva patients treated with implant-supported fixed prosthesis, and it is worthy of clinical extend.
NCT05191433
The diaphragm is the fundamental muscle of the respiratory system. The diaphragmatic dysfunction is present in 60% of critical patients at hospital admission and up to 80% after prolonged mechanical ventilation and difficult weaning. Risk factors associated with diaphragm dysfunction and atrophy are sepsis, trauma, sedatives, steroids, and muscle relaxants. The main pathology characteristics of diaphragm biopsies of mechanically ventilated patients are atrophy and a reduction in contractility, determining an impact on the clinical outcome. Shi et al. found a higher section area of the diaphragm muscle fiber in biopsies of post mortem COVID-19 patients versus negative patients, independently from days of mechanical ventilation. The hypothesis of our study is to identify different clusters of pathological presentation in post-mortem COVID-19 mechanically ventilated patients.
NCT03773952
This is a Phase IIa (proof of concept), randomized, double blind, placebo-controlled, multicentre clinical trial to evaluate the safety and efficacy of daily PBF-677 oral treatment during 28 days in Ulcerative colitis (UC) patients who are not receiving immunosuppressants and present mild-to-moderate activity of the disease. Enrolled patients would receive standard high doses of 5-ASA (4g), according to current clinical guidelines, and are randomized to receive also PBF-677 or placebo.
