There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to evaluate the efficacy and safety of the combination of ambrisentan and tadalafil in reducing mPAP to below 35mmHg in patients with moderate to severe Portopulmonary Hypertension (POPH) as a means to candidacy for liver transplantation.
People living with HIV-1 have high rates of cigarette smoking, which may be related to nicotinic interaction with HIV-1 infection and brain function levels. The proposed project aims to understand these pathways using translational brain imaging and HIV-1 reactivation studies. The study proposes a targeted nicotine-brain investigation of the nicotinic effects in HIV-1 infection from cellular to brain circuitry levels.
This is a prospective, randomized pilot study of patients who will undergo either early or late incisional laser therapy after breast reduction surgery to alleviate scar burden at NYU Langone Medical Center. The purpose of this study is to see how well carbon dioxide (CO2) laser therapy works at preventing scar formation after surgery.CO2 laser therapy is currently being used by dermatologists and plastic surgeons to help with scarring after acne and to rejuvenate the face; its benefits are now being explored by medical professionals in dermatology and cosmetic surgery to prevent scarring after surgery.
PRECISE is a study to discover new detection, prognosis and treatment biomarkers for cancer. This is a prospective, multi-center, observational study designed to collect de-identified biospecimens and clinical data from a large cohort of participants from clinical research networks in the United States. In this study, the investigators propose creating a large-scale normalized panomics dataset specifically designed for deep learning-based in silico analysis for biomarker discovery.
The goal of the study is to compare postoperative symptom scores and endoscopy findings between in patients who receive either nasal saline rinses, saline + budesonide, and saline + topical antibiotics and budesonide following endoscopic sinus surgery.
The goal of the proposed study is to develop and implement a comprehensive strategy to address pain management in the inpatient setting while appropriately managing pain and optimizing patient safety in the inpatient setting. This strategy involves developing a new health Information Technology tool in the Omnicell and electronic medical record, implementing a "menu" of pain management and relaxation strategies, and developing educational materials for staff and patients to change the culture of pain management.
Insufficient uterine tone resulting in atony can potentiate hemorrhage and adverse outcomes for the parturient. Oxytocin is the first pharmacologic agent used, followed by methylergonovine, carboprost, and misoprostol. The American Congress of Obstetricians and Gynecologists (ACOG) recommends the sequential use of oxytocin, followed by methylergonovine, carboprost, misoprostol, then surgical intervention for cases of refractory uterine atony. Many studies have examined the effect and dosage of intravenous uterotonics, including oxytocin. Although there are anecdotal reports of using intravenous bolus or rapid infusion of methylergonovine, no randomized trial has compared efficacy and side effects of these two routes of administration. Investigators hypothesize that intravenous methylergonovine reduces the time to adequate uterine tone (the tone at which the uterus is adequately contracted to prevent atony after delivery of neonate), decreases the total dose of methylergonovine to contract the uterus, and therefore produces fewer side effects of hypertension, nausea, and vomiting. Reducing the time to achieve adequate uterine tone is likely to decrease postpartum hemorrhage.
This study aims to elucidate the role of Chemokine and chemokine receptor in the pathogenesis of Psoriasis by using human psoriasis skin xenograft SCID mouse model. The hypothesis is that chemokine and chemokine receptor play important roles in psoriasis and establishment of human skin xenograft mouse model provide excellent platform to test the hypothesis.
This study will evaluate the addition of lidocaine % transdermal patches to standard therapy in the treatment of acute non-radicular low back pain in patients discharged from the Emergency Department. In addition to standard therapy, half of the participants will receive medicated patches while the other half will receive non-medicated patches.
This pilot clinical trial studies how well contrast-enhanced ultrasound in diagnosing patients with liver cancer who are undergoing Yttrium-90 radioembolization. Contrast-enhanced ultrasound may provide detailed imaging of the tumor arteries after the injection of a contrast-agent consisting of microbubbles, and may predict how much Yttrium-90 will deposit in the tumor.
