NCT ID: NCT04320537 Completed - Clinical trials for Brain Metabolic Changes During Marijuana Abstinence

Brain Neurochemical Profile During Marijuana Abstinence

Start date: July 1, 2017
Phase:
Study type: Observational

We have interviewed more than 120+ candidates and recruited 44 chronic marijuana users and 11 non-user healthy controls: 26 of the 44 MJ users actually participated in the study, 6 of the 26 MJ participants dropped out after their baseline magnetic resonance (MR) visits and the remaining 20 participants completed the study protocol, namely completed three MR visits for measurement of brain metabolites (baseline, day 7, and day 21); among the 11 healthy controls, 10 completed the study protocol. We are currently analyzing collected data and preparing manuscripts for peer reviewed journals.

NCT ID: NCT04319614 Completed - Clinical trials for Robotic-assisted Radical Prostatectomy

Can the Prophylactic Administration of Tranexamic Acid Reduce Blood Loss After Robotic-assisted Radical Prostatectomy?

RARPEX
Start date: February 24, 2020
Phase: Phase 4
Study type: Interventional

The prophylactic administration of tranexamic acid reduces blood loss during procedures at high risk of perioperative bleeding. Several studies in neurosurgery, cardiac surgery, and orthopedics confirm this finding. The aim of this study is to evaluate the effect of tranexamic acid on peri-and postoperative blood loss and incidence and severity of postoperative complications. A prospective, double-blind, randomized study is conducted to evaluate the effect on several parameters. Based on pilot study data the investigators decided to include 200 patients in the period from February 2020 to March 2022. The patients will be randomly assigned to study and control groups of 100 patients each. The minimum follow-up will be 3 months.

NCT ID: NCT04319341 Completed - Clinical trials for Antiphospholipid Antibody Syndrome in Pregnancy

Obstetric Antiphospholipid Antibody Syndrome : Contribution of the Evaluation of ADAMTS13 Made at the Diagnosis of Pregnancy on Evaluation the Risk of Pre-eclampsia

NOH-ADAMTS
Start date: April 1, 2020
Phase:
Study type: Observational

Study based on data concerning the first pregnancy treated and followed up after the diagnosis of oAPS in the NOH-APS cohort, according to clinical results already published; and on a thematic library collected and preserved at the time of the positive pregnancy test. ADAMTS 13 will be explored in the available samples defined above: ADAMTS13 antigen (presence of the molecule), ADAMTS13 activity (VWF proteolysis activity of the molecule), global autoantibodies against ADAMTS13 (plasma antibodies recognizing solid phase insolubilized ADAMTS13), these 3 parameters for the description of ADAMTS13 being measured using commercially available diagnostic kits, ELISA type, Technozyme® range, Technoclone, Vienna, Austria. The clinical endpoint evaluated will be the occurrence (yes/no) of preeclampsia, which is assessed globally, all subtypes combined. Then evaluated according to subtype: late preeclampsia from 34 weeks, early preeclampsia before 34 weeks, eclampsia (convulsions), HELLP syndrome, preeclampsia associated with the birth of a small-for-gestational-age child (defined at percentile 10 of the tables adjusted for gestational age and sex; severe: defined at percentile 3), preeclampsia associated with a retro-placental hematoma, ...

NCT ID: NCT04319055 Completed - Clinical trials for Artificial Intelligence

AI-Assisted Facial Surgical Planning

Start date: January 1, 2009
Phase:
Study type: Observational

Computer vision using deep learning architecture is broadly used in auto-recognition. In the research, the deep learning model which is trained by categorized single-eye images is applied to achieve the good performance of the model in blepharoptosis auto-diagnosis.

NCT ID: NCT04318652 Completed - Clinical trials for Epiphora Due to Insufficient Drainage

OCT Guided Punctal Stenosis Management

Start date: September 2, 2018
Phase: Phase 4
Study type: Interventional

This is a clinical trial study that was conducted on patients with punctal stenosis.We studied the diameter of stenosed puncta before and after treatment with preserved free steroid eye drops using AS-OCT.

NCT ID: NCT04318093 Completed - Clinical trials for Acute Decompensated Heart Failure

Study of the Safety of BMS-986259 in Participants With Post-Acute Decompensated Heart Failure

Start date: November 6, 2020
Phase: Phase 2
Study type: Interventional

The purpose of the study is to assess the safety of BMS-986259 in stable participants hospitalized for acute decompensated heart failure.

NCT ID: NCT04318015 Completed - COVID-19 Clinical Trials

Hydroxychloroquine Chemoprophylaxis in Healthcare Personnel in Contact With COVID-19 Patients (PHYDRA Trial)

PHYDRA
Start date: April 14, 2020
Phase: Phase 3
Study type: Interventional

Triple blinded, phase III randomized controlled trial with parallel groups (200mg of hydroxychloroquine per day vs. placebo) aiming to prove hydroxychloroquine's security and efficacy as prophylaxis treatment for healthcare personnel exposed to COVID-19 patients.

NCT ID: NCT04317963 Completed - Clinical trials for Clostridium Difficile Infection

Real-world Evaluation of Bezlotoxumab for the Management of Clostridioides Difficile Infection

Start date: February 12, 2020
Phase:
Study type: Observational

This is a retrospective case:control study examining the use of adjunctive bezlotoxumab to standard C. difficile infection (CDI) treatment compared to standard CDI treatment alone in patients with CDI seen in an academic medical center's specialty outpatient clinic.

NCT ID: NCT04317781 Completed - Clinical trials for Blastic Plasmacytoid Dendritic Cell Neoplasm

Tagraxofusp in Treating Patients With Blastic Plasmacytoid Dendritic Cell Neoplasm After Stem Cell Transplant

Start date: March 27, 2020
Phase: Phase 2
Study type: Interventional

This phase II trial studies the side effects of tagraxofusp in treating patients with blastic plasmacytoid dendritic cell neoplasm after stem cell transplant. Tagraxofusp is a type of immunotoxin that is made by linking a protein called IL-3 to a toxic substance. Tagraxofusp may help find cancer cells that express IL-3 and kill them without harming normal cells.

NCT ID: NCT04316975 Completed - Clinical trials for Barretts Esophagus With Dysplasia

Utility Of Mutational Load As A Predictor For Endoscopic Treatment Response In Barrett's Esophagus

Start date: April 10, 2020
Phase: N/A
Study type: Interventional

To evaluate association between mutational load (ML) from esophageal biopsy specimens in pre-endoscopic eradication therapy (EET) in Barrett's Esophagus (BE) or Intramucosal adenocarcinoma (IMC) patients and treatment resistance (treatment resistance will be defined as disease recurrence and/or need for additional intervention such as increased acid suppression, need for anti-reflux surgery, or use of alternate ablative modality).
