NCT03437798
Despite significant improvement in treating periodontal disease (PD) and the identification of multiple risk factors, little is known about the specific contribution of genetics to PD pathogenesis. Several genomewide association studies (GWAS) of PD have been published, but only one reported locus has reached the threshold for genome-wide significance. Epidemiological studies and biological experiments established associations and suggested common pathogenetic pathways between PD and cardiovascular disease (CVD), diabetes (DM), and osteoporosis. The overall objective is to identify genetic loci for PD as a first step toward a better understanding of PD pathogenesis. In a preliminary study in the Women's Genome Health Study (WGHS), new-onset cases of PD were associated with a family history of myocardial infarction (MI). Further preliminary analyses presented shared phenotypic variation of PD/CVD, PD/DM, or PD/osteoporosis that could be accounted by the whole-genome genetic matrices. Several variants from the GWAS catalog of bone density and family history of MI were found correlated with PD in the WGHS. Based on these findings and the literature, the central hypothesis is that there are common pathogenetic links between PD and these other diseases and that GWAS using the comorbidity case definitions will help identify potential common loci.
NCT04427397
In this study, all subjects will be given an electric toothbrush. Half of the participants will be instructed on how to use the Sulcular Bristle Tip Technique (SBTT). The other half of participants will be asked to follow the brushing instructions in the user manual. The study's primary aim is to compare the use of the SBTT with an electric toothbrush in reducing bleeding on probing with the use of an electric toothbrush used without personal professional instruction.
NCT04099810
Most publication are basing RV volumes on images acquired from the apical window. However, some data have called the practice of basing these images on apical window into question. Moreover, despite our best efforts, we have been unable, in our laboratory to reliably visualize RV outflow from the apical view. Therefore, with an identified group of trained sonographers, we plan to conduct a head-to-head comparison of RV volumes acquired from these two windows (apical and subcostal), with comparison to gold-standard CMR.
NCT04927585

NCT02266745
This is a Phase 1/2, open-label, multi-center, non-randomized, dose-escalation study to be conducted in two parts: the Dose Escalation Phase and the Dose Expansion Phase. The Dose Escalation Phase will determine the Maximum Tolerated Dose (MTD) and recommended Phase 2 dose(s) (RP2D) of PT-112 Injection and evaluate its safety and tolerability, and PK (pharmacokinetics). The Dose Escalation Phase is complete and no longer enrolling. The Dose Expansion Phase has two cohorts: one cohort for the study of PT-112 in patients with thymoma and thymic carcinoma (Cohort A), and one cohort for the study of PT-112 in metastatic castrate-resistant prostate cancer (mCRPC) (Cohort D).
NCT05228132
This is a prospective, multi-center, single-arm study designed to assess the safety and performance of the Pristine™ Long-Term Hemodialysis Catheter.
NCT03931070
Delirium is a disturbance in attention and awareness that occurs over a short period of time. Delirium is common in critically ill patients, and poor sleep quality in the intensive care unit (ICU) often worsens delirium. We aim to lower delirium in the intensive care unit (ICU) by using ramelteon, which is a drug used to improve sleep at night.
NCT03842384
In prior studies, the investigative team developed a combined computer- and text message-delivered personalized-feedback intervention (iENDURE) designed to enhance motivation and improve tolerance of distress to support the early phase of buprenorphine treatment. Specific aims of this subsequent study include conducting a preliminary randomized controlled trial with 80 participants to examine the efficacy of iENDURE relative to Treatment-as-Usual (TAU).
NCT06354465
This qualitative study investigates the potential benefits and challenges of using a once-a-month injectable medication, known as extended-release buprenorphine (XR-B), to treat individuals with opioid use disorder (OUD) within a correctional setting. The research aims to understand if XR-B can be a feasible and effective alternative to the standard daily treatment and to identify which groups within the prison population may benefit the most from this treatment. In-depth interviews are conducted with incarcerated individuals and relevant stakeholders.

NCT05709184
The goal of this clinical trial is to test whether lyophilized fecal microbime transfer - a dried extract of bacteria from the stool of healthy donors - is better than antibiotic therapy only for treating primary clostridioides difficile infection (CDI) in adult participants. The main question it aims to answer is whether lyophilized fecal microbiome transfer lowers the number of episodes of CDI compared to antibiotic therapy. Participants will be assigned to one of two groups: * In the intervention group participants will be given vancomycin by mouth for five days followed by 5 days of capsules of lyophilized fecal microbiome to swallow, up until day 10. * In the control group participants will be given vancomycin by mouth for ten days. * All participants will be asked to arrive for two follow-up visits and to fill out questionnaires. In addition, all participants will be asked to give stool samples before antibiotic therapy and on the two follow-up visits. Researchers will compare the intervention group and the control group to see if there is a difference in symptoms degree after ten days and in recurrence of the infection after two months. They will also compare side effects, the total use of antibiotics and the change in the composition of bacteria in the stool, namely the presence of bacteria that are resistant to many drugs.
