23 Clinical Trials for Various Conditions
This prospective, randomized, controlled trial will compare the incidence of nosocomial infections (composite of primary bloodstream infections, catheter-associated urinary tract infections, ventilator-associated pneumonia, and surgical site infections) that occur in intensive care unit (ICU) patients bathed with 2% chlorhexidine solution versus patients who receive standard bathing (soap and water or non-medicated cloths).
The investigators hypothesize that the use of a personal hand hygiene system (SafeHavenTM) by anesthesia providers in the adult operating room, combined with a novel infectious pathogen tracking system (OR PathTrac) will decrease participant exposure to pathologic bacteria in the adult operating room.
This is a phase 3b/4 randomized, open-label, comparative, multicenter study of the safety and efficacy of tigecycline to ceftriaxone sodium plus metronidazole in hospitalized subjects with cIAI (Complicated Intra-Abdominal Infection). Subjects with clinical signs and symptoms of cIAI will be included for enrollment. Subjects will be stratified at randomization for Acute Physiologic and Chronic Health Evaluation scale (APACHE II) score \< 10 and \> 10. Subjects will be followed for efficacy through the test-of-cure assessment. Safety evaluations will occur through the treatment and post-treatment periods and continue through resolution or stability of the adverse event(s).
Methicillin-resistant S. aureus (MRSA) infections are a common cause of morbidity and mortality in nursing home residents. MRSA is predominantly spread from patient-to-patient by health care workers. The use of gowns, gloves and hand washing prevents this spread; however, their use detracts from a patient-centered, home-like environment which is an important priority for nursing homes. The goal of this project is to determine when it is most important for health care workers to wear gowns and to wash their hands when caring for MRSA colonized Veterans in community living centers.
This pilot study in our medical intensive care unit will evaluate the clinical and cost-effectiveness of an active surveillance program for methicillin-resistant Staphylococcus aureus (MRSA), compared to routine daily bathing with chlorhexidine gluconate (CHG)-impregnated cloths. Outcomes include rate of MRSA acquisition, and of other hospital-acquired infections (e.g., catheter-associated bloodstream infections).
This study is comparing 45 minute and 30 minute treatment durations with the UVX corneal cross linking system to treat corneal infections.
This study will evaluate the Safety and Effectiveness of the UV-X System for Corneal Collagen Cross-Linking in Eyes with Corneal Infection. The treatment of UV-X system is to use the eyedrops of the riboflavin, also known as vitamin B2, and ultraviolet A (UVA) light. The eye drops are placed in affected eye and then affected cornea is exposed to UVA. UVA/riboflavin corneal collagen cross-linking was first used to treat patients in 1998 in Dresden, Germany. Data to date obtained mostly by physicians outside the United States has strongly suggested this treatment as an acceptable alternative, and many subjects have had a lasting effect (no progression) 3-5 years after their initial treatment.
Background: SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from COVID-19 have symptoms that last long after the active infection ends. This is called long COVID. Sometimes, long COVID can affect the nerves and cause problems with sleep, thinking, the senses, and movement. Researchers want to find out whether people with long COVID have retained inactive remnants of SARS-CoV-2 in their bodies. Objective: To collect tissue samples to see if people with long COVID have remnants of SARS-CoV-2 in their bodies. Eligibility: People 18 years or older who have recovered from COVID-19, both with and without neurologic symptoms. Design: Participants will have 2 to 4 inpatient or outpatient visits over 4 months. Each visit will last 4 to 5 days. Participants will be screened to make sure it is safe to collect tissue samples from their body. They will have a physical and dental exam. They will have imaging scans and a test of their heart function. They will complete questionnaires about their health. They will give blood, urine, saliva, and stool samples. Their sense of taste and smell will be tested. Tissue samples will be taken from the digestive tract, lungs, colon, skin, muscle, lymph nodes, nasal passages, and mouth. Participants may be numbed or sedated for some of the procedures. Swabs will be used to collect cells from inside the mouth and nose. Participants will undergo lumbar puncture. A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord. Participants will have follow-up phone calls after each clinic visit.
Adaptive Biotechnologies has developed a clinical test called T-Detect COVID Test that can identify a T-cell response to the SARS-CoV-2 virus, indicating recent or prior infection This study aims to evaluate the potential cross-reactivity of the T-Detect COVID test in participants presenting with viral upper respiratory tract infections within the assay's intended use population and testing positive for seasonal coronavirus.
Cross-sectional study is to explore the impact of painful neuropathy in the feet on function in persons living with HIV (PLHIV).
The proposed project seeks to develop and test an intervention to improve engagement in HIV and mental health care for young Black gay, bisexual and other men who have sex with men (YB-GBMSM) in Ryan White clinics.
The main purpose of this research study is to learn the rate of SARS COV-2 on HIV infected children, adolescents, and youth receiving their primary HIV care at the University of Miami Miller School of Medicine.
Lamivudine (3TC) is a nucleoside analogue indicated in combination with other antiretroviral agents for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults and children. Documented literature elucidates that simultaneous administration of multiple sorbitol-containing products could increase the potential for a significant interaction and may contribute to the lower 3TC exposures. In this study several sorbitol doses (3.2 gram (g), 10.2 g, and 13.4 g solutions) will be administered with lamivudine to investigate dose dependency and mimic the situation where multiple sorbitol-containing antiretroviral medications may be co-administered with lamivudine. It will be open label, randomized, 4-way crossover (by William's design method) design at a single centre. Randomized participants will receive a single dose of each of four treatments after wash out period of minimum 7 days.
The primary purpose of this study is to determine if patients randomized to corneal collagen cross-linking plus medical therapy will have a lower prevalence of positive bacterial or fungal cultures immediately after the procedure than patients who received medical therapy alone. The secondary purpose of this study is to determine if patients randomized to corneal collagen cross-linking will have a better visual acuity at 3 and 12 months than patients who receive medical therapy alone.
Background: - Bronchiectasis is a type of lung condition in which the lungs airways are abnormally stretched and widened. This stretching and widening makes it difficult for mucus and other substances to move out of the lungs, encouraging the growth of bacteria and leading to breathing problems or infection. Bronchiectasis can be caused by genetic disorders or diseases such as tuberculosis or rheumatoid arthritis. Researchers are interested in developing better ways to diagnose and treat a lung problem called idiopathic or unexplained bronchiectasis. Objectives: - To better describe the physical characteristics, radiographic patterns, and airway microbiology of unexplained bronchiectasis and to look for possible genetic links or risk factors. Eligibility: * Individuals at least 18 years of age who have a chronic cough and who have had a CT scan that has revealed signs of bronchiectasis. * Current smokers or those who have smoked for at least 10 years, as well as individuals who have known causes of bronchiectasis or who have had organ transplants, are not eligible to participate. Design: * Participants will have one outpatient clinic visit for evaluation with a physical examination including detailed body size measurements and medical history and for collection of blood samples for routine lab tests and genetic analyses and a chest x-ray if no recent one is available. * Participants will also have tests of lung function, and measurement of a gas called nitric oxide in the nose. Participants whose initial tests show abnormal results may also be asked to have a nasal scrape to collect cell samples and/or a skin sweat test to measure salt concentrations. * Participants will also have a sputum specimen collected during the visit and will be asked to collect two additional early morning sputum samples and a mouth rinse at home within 2 weeks of the clinic visit, and mail the sample collection materials to the research team.
This study will examine the safety and effectiveness of ranitidine (Zantac) in patients with Hyper-IgE recurrent infection syndrome, a disease characterized by recurrent infections of the ears, sinuses, lungs and skin, and abnormal levels of the antibody immunoglobulin E (IgE). Patients age 2 and older who have Hyper-IgE recurrent infection syndrome and who have had chronic or frequent infections in the last 12 months may be eligible for this study. Participants are randomly assigned to take ranitidine or placebo in pill or liquid form twice a day for 12 months. In addition to treatment, patients undergo the following procedures during visits scheduled on day 0 of the study (baseline) and at 3, 12, 15 and 24 months. Evaluations at 6, 9, 18 and 21 months are by telephone. * Medical history and physical examination - baseline and 3 and 24 months. * Clinical severity score - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months. * Dermatology exam - baseline and 3, 12, 15 and 24 months. * Pulmonary function test - baseline and 12 and 24 months. * Chest CT - baseline and 12 and 24 months. * Quality of life assessment - baseline and 3, 12, 15 and 24 months. * Pregnancy testing - baseline and 3, 12, 15 and 24 months. * HIV test - baseline and 12 and 24 months. * Contraception evaluation - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months. * Missed school/work days assessment - baseline and 3, 12, 15 and 24 months. * Medication adherence - baseline and 3, 6, 9, 12, 15, 18, 21 and 24 months. In addition to the above procedures, participants who are not enrolled in study 00-I-0159 have a baseline scoliosis series and genetic consult.
The main goal of this study is to find out how the immune system responds to a specific type of HIV infection, known as C HIV-1, in order to develop a vaccine against this type of infection. The study involves Southern African populations. The HIV-1 virus changes rapidly and many different subtypes have been found. In South Africa, limited data have suggested Subtype C HIV-1 is the most common. This study strives to verify the most common subtype and also look at genetic differences and immune responses among newly infected individuals. Results will aid in the development of vaccines specific for certain geographical areas.
This study will compare the structure, chemical composition and other characteristics of skin and blood in people with and without parasitic infections. Cell samples will be taken from blisters produced by suction blistering. This study may provide new information about the interactions between parasites and the immune system that could lead to better treatments for these infections. Normal volunteers and patients with acute helminth (a type of parasite) infections aged 18 years older may be eligible for this study. Following a medical history and physical exam, participants will undergo suction blistering to provide cells needed for study. A suction blister device is attached to the skin of the thigh. A heating element in the device heats the skin to speed blister formation. (This will feel only a slightly warm.) The device is removed after about two hours, when the blisters have formed. The blister tops are removed with sterile scissors. The blistered areas are then treated with special dressings to promote healing and the participant is discharged with further wound care instructions. A small amount of blood (around four tablespoons) may be drawn to compare chemicals in the blood with chemicals in the blister fluid. Participants will be contacted by telephone over the next 72 hours to check on healing. Further follow-up will occur by phone at 6 months and 1 year. Up to 60 blisters may be produced over a one-year period (in three separate sessions every six months) with no more than 20 raised per session....

To determine whether reductions in ionized magnesium, ionized calcium, and parathyroid hormone levels following foscarnet infusions are lessened by preinfusion of magnesium sulfate. To evaluate the safety of intravenous magnesium sulfate prior to foscarnet infusion by monitoring blood pressure, heart rate, and heart rhythm. To characterize the effect of magnesium sulfate on foscarnet blood levels and urinary excretion of calcium, magnesium, phosphate, and foscarnet.
The purpose of this study is to test whether the group B meningitis vaccine (brand name Bexsero™) induces immune responses against the bacteria that causes gonorrhea. Participants: Approximately 15 Individuals who are 18-25 years of age that are not pregnant, HIV negative, have no history of congenital immunologic disorder, and are not taking immune suppressive medications will be enrolled on this study at a single site, University of North Carolina at Chapel Hill (UNC-CH). Procedures (methods): Participants will receive two-doses of an FDA-approved vaccine that provides protection from N. meningitidis infection according to the recommended dosing schedule. The first vaccine dose will be given to participants at the entry visit and the second vaccine dose will be given to participants at the week 5 visit. The participants will provide samples of blood as well as mucosal surface derived samples (urine and/or swabs) at four separate visits (entry, week 5, week 6, and week 7).
This study is divided in 2 parts. Part 1a is being conducted to evaluate the safety, tolerability, and relative bioavailability of the 2 free base tablet formulations (roller compacted \[RC\] and high shear wet granulation \[HSWG\]) compared to the reference capsule formulation under fasted conditions. This is a 3-period; cross-over study that will guide which gepotidacin formulation will be used for future studies. Following review of pharmacokinetic (PK) and safety data in Part 1a, a decision will be made whether to proceed with Parts 1b and 2. Part 1b is a 2-period, cross-over study and will assess the effect of food on the PK of the selected gepotidacin tablet formulation from Part 1a. In Part 2, the PK of the selected gepotidacin tablet formulation from Part 1a in Japanese (2a) and Chinese (2b) subjects will be evaluated under fasted conditions. The duration of the study (from Screening to the Follow-up visit) will be approximately 44 days (Part 1a), 41 days (Part 1b) and 38 days (Part 2a and 2b each), respectively. The approximate number of subjects enrolled in Part 1a will be 27 (9 subjects in each of the 3 treatment sequences), 16 in Part 1b (8 subjects in each of the 2 treatment sequences) and 12 Japanese and 12 Chinese subjects in Part 2a and 2b, respectively.
The purpose of this study is to determine the safety, local tolerability and pharmacokinetic parameters of TOL-463 intravaginal dosage forms in both healthy, nonpregnant females following single dose administration (Part 1), and in nonpregnant women with vaginitis following multi-dose administration (Part 2).
Guidelines have continued to list lopinavir/ritonavir as a preferred protease inhibitor-containing regimen for HIV-infected individuals. There has recently been increasing interest in once daily therapy. While lopinavir/ritonavir has recently been approved as a once daily therapy it was associated with considerable diarrhea in those treated with soft gel capsules. It is the hope that alternative formulations of lopinavir/ritonavir may provide similar pharmacokinetics with improved tolerability. This includes the possibility of using liquid or newly released tablets. This study will treat people tolerating their current regimen with up to four weeks of each formulation with several assessments of pharmacokinetics and tolerability for each.
