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.
This study will evaluate if an intervention using academic detailing and audit and feedback impacts the specific pacemaker or implantable cardioverter-defibrillator (ICD) lead models implanted in Veterans.
Iron-deficient anemia is a chronic problem in sub-Saharan Africa and other developing areas of the world. From our previous research, the investigators have shown that certain local plant foods in Kenya and Senegal have an unusual action of improving in vitro iron bioaccessibility (nearly doubling the low value obtained in cereals). The investigators will assess absorption of stable isotopes of iron (57Fe, 54Fe and 58Fe) extrinsically labeled in a serving of porridge fortified with various combinations of moringa, baobab, mango, carrot and standard fortificant iron sulfate and the enhancer ascorbic acid.
The purpose of this study is to review the clinical outcomes following hand ligament reconstruction surgery using allograft (cadaveric) knee collateral ligaments. Currently, there is no standard procedure or devices used for hand ligament reconstruction surgery, although most techniques use some form of autograft (patients' own tissue) for the reconstruction. We believe that the use of allograft ligaments in reconstruction may eliminate the pain associated with procuring the patients' own tissue for the procedure, and prove to be a viable and preferred alternative to the multiple techniques currently used. The main procedures of this study include wrist and hand ligament reconstruction surgery (for wrist scapholunate (SL) ligaments, thumb ulnar collateral ligaments (UCL), and finger proximal interphalangeal (PIP) joint collateral ligaments) using allograft ligament, and subsequent follow up appointments where measurements and questionnaires will be completed to evaluate how hand function is doing after surgery.
Bipolar disorder is a common condition that can cause significant disability and risk for suicide. Second generation antipsychotic medications can be used to treat depression in bipolar disorder, yet we do not know how they work. Here, we will use a recently approved medication, cariprazine (Vraylar), to treat participants with bipolar depression. They will have brain imaging with PET scans before and during treatment to understand how the medication may be working. Particularly, we will look at the role of the D3 dopamine receptor.
The aim of the 6 month randomized controlled trial is to investigate the feasibility of a novel progressive muscle resistance exercise in postmenopausal women with low bone mass.
Cystinuria is an inherited autosomal recessive disorder of the kidney that is the result of an inability to reabsorb dibasic amino acids, including cystine, from the urine. Supersaturation of cystine in the urine produces crystals that precipitate and form stones in the kidney, which can be a cause of obstruction, infection, and chronic kidney disease. Cystine stones constitute a major health challenge for affected individuals with cystinuria because of the frequent recurrence of painful symptoms and the current absence of effective, patient-accepting treatment. A mainstay of therapy is breaking or preventing the cystine bond on the molecular level such that cystine (which is formed from the joining of two cysteine amino acids and their corresponding sulfur atoms) cannot precipitate in the urine. It is hypothesized that a glucose molecule may be able to do this if introduced into the urine. SGLT-2 inhibitors are a class of drug that are FDA approved to treat diabetes mellitus (DM) and heart failure by inhibiting an enzyme in the kidney that allows for reabsorption of glucose from the urine. This effectively increases the concentration of glucose in the urine. The hypothesis suggests that administration of this drug to patients with cystinuria will introduce sufficient glucose into the urine to prevent or reverse the formation of cystine stones. To date, there has been no published data on the effectiveness of this therapy for this indication, although the dosage and administration would be identical to that already approved by the FDA for the treatment of DM and heart failure.
The hypothesis is that intranasal dexmedetomidine will provide significantly more effective analgesia and anxiolysis for subjects undergoing a simple laceration repair when compared to either intranasal fentanyl or intranasal midazolam. Additional hypotheses include that there will be 1) no significant increase in adverse effects between drugs and 2) significantly higher satisfaction rates for both subject experience and ease of laceration repair based on structured, proceduralist feedback.
This study will involve the collection of follow-up data for patients who previously participated in the Sjogren's International Clinical Collaborative Alliance (SICCA) study at the University of Pennsylvania. Clinical data and specimens will be collected from subjects with objective evidence of dry eye who were or were not diagnosed with Sjogren's syndrome at the time of their initial participation in the SICCA study. Specimens will be collected from participants which will include tears, saliva, whole blood, serum, DNA and possible labial minor salivary gland biopsies when indicated. All individuals will participate in a standard evaluation protocol including an oral, ocular and physical examination, objective tests for dry eyes and dry mouth and, whenever necessary, a labial minor salivary gland biopsy. The biopsy requirement is waived for those who have already had positive lip biopsies in the past.
The purpose of this research study is to find out if autologous "neo-bladder" construct for the treatment of fibrotic and/or contracted bladder can improve bladder compliance and be safe long term. The neo-bladder is like a reservoir or pouch that will be surgically attached to the bladder to assist with urine collection.
The overall objectives of this study are to investigate the efficacy of extended cannabis treatment to reduce patient exposure to prescription opioids through its use 1) as a non-opioid analgesic treatment, and 2) as a therapy for reducing high-dose opioid use in patients with chronic spine pain.
