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.
Transbronchial cryobiopsies are common procedures used to obtain tissue samples from airways for diagnostic purposes. While these procedures are safe, there is a risk of bleeding from the biopsy site. We are conducting a research study to assess the safety and effectiveness of using tranexamic acid prior to undergoing a transbronchial cryobiopsy.
This project is the first stage of a health promotion campaign to shift social norms about marketing and feeding children ultra-processed foods. Embedded within a longitudinal ethnographic study using photo-elicitation techniques, mothers of preschool-age children will be randomly assigned to arts-based or traditional education about ultra-processed food.
This study will compare the effectiveness of two different treatments for preventing infection from frostbite injuries. These two treatments are A) aloe vera and B) long-acting silver wound dressings. The investigators will also study the safety and effectiveness of Dalbavancin, an FDA approved antibiotic used for treating people who develop frostbite wound infections, as well as evaluate how frostbite damage to individuals' bodies may affect how fast their kidney clear drugs from their systems.
The overall objective of this application is to pilot test an mHealth nutrition intervention within pediatric clinics serving Latino families and evaluate its potential for implementation. The investigators hypothesize the intervention will improve child diet quality and will be feasible for use within the clinic setting. To test this hypothesis, the investigators will pursue 3 specific aims and 1 exploratory aim: 1. Aim 1: Pilot Nutricity with 40 Latino families (English or Spanish speaking) vs. 40 waitlist control in primary care clinics and estimate differences in child diet quality at 3 month's post Nutricity exposure. Preliminary data will inform power calculations for a future larger Nutricity intervention. 2. Aim 2: Evaluate other individual (dyad) level factors including reach, engagement, and changes in secondary effectiveness outcomes (e.g. nutrition literacy, BMI, skin carotenoid, psychosocial constructs) at 3 months post exposure. 3. Aim 3: Evaluate organizational-level factors (adoption, implementation, and organizational-level maintenance) in Latino-serving pediatric clinics that may support or inhibit future uptake of Nutricity. The investigators will seek to understand the context of interventions and scalability to other clinics using mixed methods. 4. Exploratory Aim 1: Explore the relationship among nutrition literacy, psychosocial constructs and diet quality outcomes; and explore how engagement and satisfaction influence outcomes.
Human milk has several well-established benefits but does not adequately meet the increased nutritional demands of the growing preterm infant, necessitating additional nutrient supplementation in a process known as fortification. In U.S. neonatal intensive care units (NICUs), human milk is primarily supplemented using standardized fortification, in which a multicomponent fortifier is added to human milk to achieve assumed nutrient content based on standard milk reference values. However, this method does not account for the significant variability in human milk composition or in preterm infant metabolism, and up to half of all very premature infants experience poor growth and malnutrition using current nutritional practices. Poor postnatal growth has adverse implications for the developing preterm brain and long-term neurodevelopment. Recent advances allow for individualized methods of human milk fortification, including adjustable and targeted fortification. Adjustable fortification uses laboratory markers of protein metabolism (BUN level) to estimate an infant's protein requirements. In targeted fortification, a milk sample is analyzed to determine its specific macronutrient and energy content, with additional macronutrient supplementation provided as needed to achieve goal values. Emerging data suggest that both methods are safe and effective for improving growth, however information on their comparable efficacy and neurodevelopmental implications are lacking, particularly using advanced quantitative brain MRI (qMRI) techniques. Through this prospective, randomized-controlled trial, the investigators will compare the impact of individualized human milk fortification on somatic growth and neurodevelopment in preterm infants. Infants will be randomized to receive one of three nutritional interventions: standardized (control group), adjustable, or targeted human milk fortification. Infants will undergo their assigned nutritional intervention until term-equivalent age or discharge home, whichever is achieved first. Brain qMRI will be performed at term-corrected age, and neurodevelopmental follow-up will be performed through 5 years of age.
Tonsillectomy ± adenoidectomy (T&A) is one of the most common surgical operations with over 500,000 pediatric T&As performed annually in the United States. Unfortunately, despite advances in anesthetic and surgical techniques, moderate-severe post-tonsillectomy pain (PTP) remains a significant problem affecting up to 62% of children. PTP is thought to arise from pharyngeal mucosal inflammation, which produces local nerve irritation and pharyngeal muscle spasm. Patient factors and surgical techniques also play major roles. Race is an important phenotypic risk factor for moderately severe early PTP. The underlying molecular basis of this differential pain experience is presently unknown. This gap in knowledge means that therapies are poorly targeted and often unsuccessful. Indeed, treatment options for PTP have not advanced substantively for many years. Metabolomics provides novel opportunities to investigate common and unique "metabolic signature" of PTP through the analysis of low molecular weight compounds produced in response to tissue injury. Therefore, the central themes of this proposal are that (1) PTP is a complex process that may be determined by molecular level factors such as preoperative systemic inflammation and metabolic profile, and (2) these molecular level factors may explain the excess burden of PTP among minority children. Here the investigators seek to utilize a combined clinical, biological and untargeted metabolomics approach to identify candidate small and large serum molecules that may influence the frequency and severity of PTP in children across racial groups. This approach to exploring the molecular basis of PTP is novel and knowledge from the study should substantially enhance understanding of the mechanisms underlying pediatric PTP - and narrow the racial disparities in post-operative pain.
The scientific premise of this research is that individual, interpersonal, and structural factors impact Black girls' sexual reproductive health outcomes (sexually transmitted infection (STI) and Human Immunodeficiency Virus (HIV)) and experience of sexual violence. This study expands STI/HIV prevention programs to include Black male caregivers, a potentially valuable yet underutilized resource to protect Black girls and reduce their exposure to STI/HIV and sexual violence.
The purpose of this study is to investigate the responses of the brain region known as the subgenual anterior cingulate cortex (sgACC) during transcranial magnetic stimulation (TMS) in individuals with depression. Specifically, investigators aim to determine whether the sgACC is engaged when TMS is delivered to specific targets and if the engagement of sgACC changes throughout a full TMS treatment intervention. To achieve this goal, the investigators will employ a combination of TMS and Magnetic Resonance Imaging (MRI) procedures. Study participation will include completing various questionnaires, clinical assessments, receiving a full transcranial magnetic stimulation (TMS) treatment intervention (every weekday for 4-6 weeks), and undergoing MRI scans, both with and without concurrent TMS.
The CATS Tonometer prism clinical study is intended to determine repeatability of intraocular pressure measurement in human corneas which have undergone a LASIK procedure when compared to a standard Goldmann prism, validating the human LASIK eye findings comparing CATS Tonometer and Goldmann prisms to intracameral pressure in cadaver eyes.
The main purpose of this study is to gather information about an investigational drug combination, Lenvatinib in combination with pembrolizumab, that may help to treat cervical cancers. In this study, we are looking to see whether the combination of lenvatinib and pembrolizumab has any effect on slowing tumor growth in cervical cancer tumors.
