The Impact of Renal Transplant on Coronary Microvascular Function Among Patients With Advanced Chro1

People with chronic kidney disease (CKD) often experience faster aging of the heart and blood vessels, which raises the risk of heart problems beyond traditional factors like high blood pressure or cholesterol. One early sign is reduced blood flow in the tiny vessels that supply the heart, measured by a positron emission tomography (PET) scan using a marker called myocardial flow reserve (MFR). In CKD, ongoing inflammation and abnormal blood vessel growth can damage these small vessels, leading to heart stiffness and weaker heart function. A kidney transplant offers a unique chance to study how better kidney function and reduced inflammation affect heart health. The observational RESTORE study ("Impact of Renal Transplant on Coronary Microvascular Function in Patients with Advanced CKD") will measure heart blood flow and function before and after transplant. The study will test whether: 1. Inflammation and abnormal vessel growth are linked to poor heart blood flow and heart function in CKD. 2. Kidney transplant improves heart blood flow and function. 3. Lower inflammation after transplant leads to better heart health. By understanding how kidney disease and inflammation affect the heart-and how transplant may reverse these effects-this research could help guide future treatments to better protect heart health in patients with CKD.

The goal of this observational study is to measure shear wave velocity (SWV) in patients with non-reduced left ventricular ejection fraction (LVEF) heart failure and left ventricular hypertrophy, with or without transthyretin amyloidosis with cardiomyopathy (ATTR-CM), and in control subjects without heart failure or cardiomyopathy. The main question it aims to answer is: • Can SWV be used to measure myocardial and liver stiffness in the study's target populations? Researchers will compare patients with ATTR-CM, patients without ATTR-CM, and a control group to determine the distributions of SWV in each population. Participants will: - Have a standard cardiology assessment, including a physical exam, blood work, and an echocardiogram. - Undergo an investigational assessment with the eMyosound LYRA device to measure SWV in their myocardium and liver. - Have the investigational assessment repeated by a second observer to assess measurement reliability.

The hypothesis of this research protocol is that the investigators will be able to redesign the manner in which upper limb amputations are performed so as to enable volitional control of next generation prosthetic devices and restore sensation and proprioception to the amputated limb. The investigators will test this hypothesis by performing modified above elbow or below elbow amputations in ten intervention patients, and compare their outcomes to ten control patients who have undergone tradition amputations at similar levels. The specific aims of the project are: 1. To define a standardized approach to the performance of a novel operative procedure for both below elbow (BEA) and above elbow amputations (AEA) 2. To measure the degree of volitional motor activation and excursion achievable in the residual limb constructs, and to determine the optimal configuration and design of such constructs 3. To describe the extent of proprioceptive feedback achievable through the employment of these modified surgical techniques 4. To validate the functional and somatosensory superiority of the proposed amputation technique over standard approaches to BEA and AEA 5. To develop a modified acute postoperative rehabilitation strategy suited to this new surgical approach This will be a phase I/pilot clinical trial to be performed over a three-year period as a collaborative initiative involving Brigham & Women's Hospital/Brigham & Women's Faulkner Hospital (BWH/BWFH), Walter Reed National Military Medical Center (WRNMMC), and the Massachusetts Institute of Technology (MIT). The investigators will plan to perform 6 of the 10 amputations at BWH/BWFH, and 4 of the amputations at WRNMMC.

The investigators have developed a new technology, termed in-vivo laser capture microdissection (IVLCM), that addresses the limitations of endoscopic biopsy for screening for BE and provides targeted genomic profiling of aberrant tissue for more precise prediction of EAC risk. The device is a tethered capsule endomicroscope (TCE) that implements optical coherence tomography (OCT) to grab 10-mm-resolution, cross-sectional microscopic images of the entire esophagus after the capsule is swallowed. This OCT-based TCE technology is used in unsedated patients to visualize images of BE and dysplastic BE. During the IVLCM procedure, TCE images of abnormal BE tissue are identified in real time and selectively adhered onto the device. When the capsule is removed from the patient, these tissues, targeted based on their abnormal OCT morphology, are sent for genomic analysis. By enabling the precise isolation of aberrant esophageal tissues using a swallowable capsule, this technology has the potential to solve the major problems that currently prohibit adequate BE screening and prevention of Esophageal Adenocarcinoma EAC.

The purpose of this study is to identify individuals 18 or older who have diagnostic presentation of adhesive capsulitis and randomize them into two arms, distinguished by use of physical therapy and steroid injections compared with steroid injections followed by watchful waiting. This prospective study will be used to determine whether there is a significant impact on patient outcome and whether the additional financial burden is justified. There are no experimental interventions for this study. The use of physical therapy, oral and parenteral corticosteroids, and watchful waiting are offered following the standard of care for adhesive capsulitis. Our hypothesis is that patients will not have a significant difference in outcome between the two study arms. One group will undergo regular physical therapy with corticosteroid injections (Arm 1) and the other will have steroid injections during the inflammatory phase only and then be regularly observed (Arm 2). We also hypothesize there will be a significant financial burden associated with the PT arm that is not justified with the possibility of increased symptom reports in that arm.
