Circadian Time Restricted Eating
NCT05628012
Recruiting
The goal of this study is to learn more about how the time in which participants consume their meals relative to their personalized circadian rhythm influences their overall cardiometabolic health and weight. The investigators are hoping to discover if a circadian-based time restricted eating intervention will improve cardiometabolic health and decrease weight. The protocol is a 46 day prospective cohort study that includes both field and in-laboratory data collection in overweight and obese ind... Read More

Sleep and Metabolism
NCT05775627
Recruiting
The goal of this study is to uncover sleep and circadian mechanisms contributing to adverse metabolic health. The protocol is a 21 day (7 outpatient days, 14 inpatient days) mechanistic randomized-crossover study designed to identify the impact of chronic sleep restriction and circadian timing, independently and in combination on energy metabolism and identify the independent and combined effects on glucose tolerance.

Lovenox 30 mg Twice Daily (BID) Versus 40 mg Once Daily (QD)
NCT02342444
Recruiting
The risk of developing a blood clot occurs in up to 60% of all critical care patients. Many times enoxaparin (or Lovenox) is given to patients who are at a higher risk of developing clots in their legs or lungs. There are two standard doses of enoxaparin that are recommended by the drug companies. These two doses have never been directly compared in trauma, general, and vascular surgery patients. The purposes of this study are: 1. to compare the development of blood clots in patients receiving... Read More

Tranexamic Acid to Reduce Contraceptive-related Bleeding Side Effects
NCT06000423
Recruiting
This randomized double blinded trial seeks to determine whether tranexamic acid (TXA) is an efficacious treatment for contraceptive induced menstrual changes (CIMC) including irregular, bothersome bleeding caused by the etonogestrel subdermal contraceptive implant (ENG implant). Participants will be randomized into the TXA treatment arm or a placebo. They will begin taking the medication after three consecutive days of bleeding. Participants will track their bleeding using an automated text mess... Read More

Collaboration Oriented Approach to Controlling High Blood Pressure
NCT06124716
Recruiting
Hypertension is a significant contributor to poor cardiovascular outcomes. Self-management support tools can increase patient behaviors to improve blood pressure. The investigators created a clinical decision support app, called COACH, to integrate home blood pressure data and goals into EHR reporting and workflow with communications informed by behavioral economics principles to support shared decision-making. The study aims to measure the effectiveness of the COACH intervention in a pragmatic... Read More

Ripasudil for Enhanced Corneal Clearing Following Descemet Membrane Endothelial Keratoplasty in Fuchs' Dystrophy
NCT03813056
Recruiting
Recently, published literature has reported that performing a descemetorhexis in combination with topical Rho kinase (ROCK) inhibitor therapy was successful in clearing edematous corneas in patients with Fuchs Endothelial Corneal Dystrophy. Ripasudil hydrochloride hydrate( Glanatec ophthalmic solution 0.4%), a potent ROCK inhibitor, has been approved in Japan since 2014 for ocular use in the treatment of glaucoma. Ripasudil acts as an IOP-lowering drug by affecting aqueous outflow through the t... Read More

A Study of TSR-022 in Participants With Advanced Solid Tumors (AMBER)
NCT06322693
Recruiting
This is a first-in-human study evaluating the anti-T cell immunoglobulin and mucin containing protein-3 (TIM-3) antibody TSR-022. The study will be conducted in 2 parts with Part 1 consisting of dose escalation and Part 2 dose expansion. Part 1 will determine the recommended Phase 2 dose (RP2D) of TSR-022 and Part 2 will evaluate the antitumor activity of TSR-022 in combination with TSR-042 or docetaxel and as monotherapy.

Evaluation of the PrevisEA Device for Predicting Gastrointestinal Impairment
NCT04880473
Recruiting
PrevisEA is a noninvasive, disposable device that uses audio spectral analysis of sounds produced by the gastrointestinal tract to predict gastrointestinal impairment (GII). GII is most commonly associated with postoperative ileus (POI), but could be the result of other causes, such as early postoperative bowel obstruction. GII is defined as failure of successful early oral re-feeding in a subject undergoing major abdominal surgery. For subjects who are allowed to resume a diet during the first... Read More
