The purpose of this study is to determine whether phase variance optical coherence tomography (PV-OCT), a software-based optical coherence tomography(OCT) image processing technology, can be used to generate angiographic images of the retinochoroidal vasculature that are comparable to those produced by fluorescein angiography (FA), the current gold standard diagnostic test.
This prospective, randomized study is intended to assess the efficacy and safety of bilateral continuous paravertebral blocks compared to continuous epidural block for open liver resection. Hypotheses: Bilateral paravertebral blocks are: 1) equally effective in controlling the perioperative pain; and 2) safe, with less frequent complications following open liver resection when compared to continuous epidural block.
This multicenter trial using Hologic digital mammography units will evaluate the specificity of 2-D full field digital mammography (FFDM) versus a combination of 2-D and 3-D tomosynthesis imaging in breast cancer screening. Specificity, in this study, will be measured by the participant call-back rate by each modality. Varying combinations of 2-D mammography and tomosynthesis projections will be evaluated to optimize the screening paradigm and limit radiation exposure when tomosynthesis is incorporated. Both prospective and retrospective imaging data will be assessed. Hypothesis: Digital breast tomography (DBT) will improve the specificity of breast cancer screening as measured by a reduction in the call-back rate while maintaining the sensitivity of cancer detection. This improved accuracy will be achieved by the optimization of the imaging sequence and number of views obtained at a capped radiation dose in the combined DBT and 2-D screening sequence.
The purpose of this study is to compare Kaletra tablets with Kaletra soft-gel capsules to see if there is any change in the side effects you may have and to see how people in the study feel about using the tablets.
This study will evaluate the reliability of a new test called Real-Time Polymerase chain reaction (RT PCR) in detecting cytomegalovirus (CMV) in the blood and predicting the course of CMV disease in patients who have recently had a bone marrow transplant. The test's effectiveness will be compared with that of the "pp65 antigenemia assay" now routinely used for this purpose. CMV is a common virus that is transmitted from person to person by close personal contact. In most healthy people, CVM can remain in the body indefinitely without causing any harm. But, in people with weakened immune systems-including those who have just undergone bone marrow transplant-CMV infection can cause serious, and possibly fatal, complications. Drugs are available to treat this infection, however. Optimum treatment depends on early and accurate detection. Patients aged 10 to 80 years who are scheduled to undergo bone marrow transplant at the NIH Clinical Center as part of an NIH protocol may be eligible for this 2-phase study. In phase 1, patients will have blood drawn for both RT PCR and antigenemia testing once before the bone marrow transplantation and then weekly for the first 100 days after the transplant. During Phase 2-which begins immediately after the end of phase 1 and continues for one year after the transplant-blood samples for both tests will be drawn up to once a week. The samples for both tests will be collected at the same time and will be taken through a catheter (a thin flexible tube inserted into a vein) that has already been placed for the transplant study. RT PCR testing will require an extra 5 milliliters (1 teaspoon) above what is needed for antigenemia testing, amounting to a maximum of about one-half pint extra over the course of the 1-year study. It is hoped that the new RT PCR test will prove to be more accurate in detecting CMV infection and predicting disease development, thus enabling doctors to plan early and effective treatment.

Persons diagnosed with thyroid cancer are often treated initially with a thyroidectomy, which is followed by ablation using Iodine-131, a therapy which has been shown to be effective and safe. Imaging of metastatic thyroid cancer has been performed with whole body I-131 and Iodine 123 (I-123) imaging for many decades and use I-123 for staging studies. Iodine 124 (I-124) is a radioisotope of iodine which emits a positron and is imaged using PET (positron emission tomography). This is a single arm prospective trial that evaluates the ability of Iodine-124 (I-124) to detect metastatic thyroid cancer compared to non-interventional, usual care I-123 and I-131 images.

This study investigated the human-animal interaction (HAI) and bond (HAB) between a canine trained in therapy techniques or a canine plush toy and youth with autism spectrum disorder (ASD) during animal-assisted therapy (AAT) sessions. The purpose of this study is to explore identified gaps in knowledge pertaining to AAT in pediatric ASD care management by documenting human interaction between either a live canine or the plush toy canine during AAT sessions and evaluating prosocial behaviors observed during and after AAT sessions. This study addressed the following research questions: 1. How do children with autism ages 2 to 18 years interact with a live canine during AAT sessions? 2. How do children with autism ages 2 to 18 years interact with a toy plush dog during AAT sessions? 3. Is there a difference in HAI in the live canine group and the toy plush dog group? 4. Is there a difference in prosocial behavior observed during AAT sessions between the live canine group and the toy plush dog group? 5. Is there a difference in behavior after AAT sessions between the live canine group and the toy plush dog group? Participants were randomly assigned to either the live canine or toy plush dog group. Adaptive functioning and social responsiveness evaluations were obtained to compare baseline behavior between the two groups. Participants attended an AAT session once weekly for 6 to 8 weeks. Each group received the same therapy provided by the therapist; the only difference being the incorporation of a live canine during the therapy session. Caregivers completed a weekly assessment depicting participants' positive and negative affect at the beginning of each session. Caregivers also completed a monthly assessment noting strengths and difficulties in social functioning and behavior at the start of the first, middle, and final session. AAT sessions were recorded and behavior occurring during the sessions was coded to note HAI and HAB that occurred during the sessions.

Participants who do not complete all study visits or terminate from the study prior to Day 15 will be asked to complete the Early Termination Visit within 1 day after withdrawal from the study. • Day 36 Telephone Follow Up Phone Call: Participants will be contacted by phone on Day 36-i.e., 28 days following the last study dose administered on Day 8. The purpose of this follow-up call is to assess for any adverse events.
To study a novel biopsy needle system for performing transperineal prostate biopsy. Prostate biopsy remains the standard approach for prostate cancer detection. While pre-biopsy MRI allows for targeting of visible lesions, systemic or 'off target' samples are recommended due to the well-recognized risk of undegrading and under sampling with current commercially available needles. The SureCore plus single-use biopsy needle produces a more intact tissue core with a same caliber 18g needle with \~21% more tissue per core in pre-clinical studies. This research study will determine if a new biopsy needle designed to produce more robust tissue cores per sample can improve detection and characterization of prostate cancer.
Many people suffer from migraine headaches, some more so than others and a common trigger/complaint is light sensitivity, or photophobia1. Some will go to great lengths to avoid light: a dark room with sunglasses on and blankets over the windows, often missing work/school/social activities, etc. Several ocular conditions are accompanied by photophobia, ranging from mild to debilitating.
The purpose of this study is to compare surgeons' discernment of 4 balloons filled with different materials when using their eyes and hands versus using the da Vinci robot.

The purpose of this pilot study was to compare two commonly employed intravenous drug combinations; I) nitrous oxide, midazolam, fentanyl, and ketamine and II) the same combination with substitution of propofol for ketamine, for use during wisdom teeth extraction. Measures of recovery, amnesia testing 20 minutes after induction and after completion of recovery tests, patient satisfaction, and surgeon satisfaction will be evaluated. The data from this pilot study will be used to obtain preliminary estimates of effect sizes and to select primary and secondary endpoints for the design of a larger scale and more definitive trial of the two anesthetic approaches.
This study seeks to identify patient reported and clinically measured outcomes for pain management and elbow function with application of semiconductor embedded fabric combined with PRP+ASC injections in the affected area.
The investigators hypothesize that Shockwave with DCB is non-inferior to surgical endarterectomy for common femoral artery (CFA) stenosis with regard to primary efficacy and safety endpoints. The study will challenge the current guideline that recommends common femoral endarterectomy (CFE) as the primary treatment for symptomatic CFA stenosis.
Dual antiplatelet therapy (DAPT) with low-dose aspirin and a P2Y12 inhibitor is the current standard of care in patients with coronary artery disease experiencing an acute event or undergoing percutaneous coronary intervention. However, the ischemic benefits are counterbalanced by a significant increase in bleeding events. Over time, different DAPT de-escalation strategies have been developed to reduce the bleeding risk while maintaining the ischemic protection, but there is currently no head-to-head comparison between them. The purpose of this clinical trial is to conduct a head-to-head comparison on the pharmacodynamic efficacy of DAPT de-escalation by dose reduction to low-dose prasugrel (5 mg od) and DAPT de-escation by switching from standard-dose more potent P2Y12 receptor inhibitor to standard-dose clopidogrel (75 mg). To determine if the PD profiles of these two strategies are comparable, we aim to conduct a non-inferiority study.
This project is being done to understand if a drain reduces recovery problems after surgery, such as infection or the need for more surgery.
