Forebrain Electroneutral Transporters in Salt-sensitive Hypertension: an MRI Study

Salt-Sensitivity of Blood Pressure

The overall objective of this project is to identify the key salt-sensing regions of the brain and determine the underlying mechanism of sodium sensing. The investigators will assess how the brain responds to an acute increase of salt in the blood using MRI. This will be done during a 30-minute infusion of a saline solution containing 3% salt. One trial will be conducted with a salt sensing channel blocker and one trial without the salt sensing channel blocker. This will help to assess the role of a specific salt sensing channel in the brain. Salt sensitivity of BP will be assessed using 7-day dietary feeding where participants will be given food to consume for 7-days. Comparisons will be made between salt resistant (no change in blood pressure going from low to high salt diets) and salt sensitive adults (a change in blood pressure going from low to high salt diets). The investigators think the changes in MRI will be greater in salt sensitive compared to salt resistant subjects.

Early Temporal Dynamics of Optic Nerve Sheath Diameter After Therapy in GCA

Giant Cell Arteritis · Temporal Arteritis · Optic Nerve Diseases

Giant cell arteritis (GCA) is an inflammatory disease of large and medium arteries that can cause irreversible vision loss. Glucocorticoids (GCs) rapidly suppress inflammation, but diagnostic imaging tests such as temporal artery ultrasound or biopsy often become falsely negative within days of treatment. The optic nerve sheath diameter (ONSD), measurable by ocular ultrasound, reflects perineural edema and may serve as a quantitative biomarker of ocular inflammation in GCA. The SONIC-TIME study (Early Temporal Dynamics of Optic Nerve Sheath Diameter After Glucocorticoid Therapy in Giant Cell Arteritis) is a single-center, prospective observational substudy embedded within SONIC-GCA (NCT05749094) at Hôpital du Sacré-Cœur de Montréal. It aims to characterize how rapidly ONSD decreases after GC initiation and how this trajectory relates to cumulative GC exposure, intravenous methylprednisolone, and early use of steroid-sparing therapies. Sixty participants with newly diagnosed GCA will undergo serial optic nerve sheath ultrasound, blood tests (CRP, ESR), and when feasible, temporal artery ultrasound over the first two months of therapy (Days 3, 7, 10, 14, 21, 28, and Month 2). No experimental treatments are given; all participants receive standard-of-care therapy. The primary objective is to quantify the percent change in mean ONSD from baseline to Day 28. Secondary objectives include modeling ONSD change over time, assessing associations with cumulative steroid dose and inflammatory markers, and estimating the time to normalization below the SONIC-GCA cutoff. Findings will define the optimal imaging window and refine the diagnostic and monitoring role of optic nerve ultrasound in GCA.

MEMRI and Kidney Disease

Acute Kidney Injury · Kidney Transplant · Vasculitis

Acute kidney injury (AKI) is common and costly.1 Although patients who suffer an episode of AKI may recover, many will go on to develop cardiovascular disease and chronic kidney disease (CKD). Cardiovascular disease is an important complication of AKI.2 Similar to AKI, CKD and kidney transplantation and kidney donation associations with cardiovascular disease.1 The risk of cardiovascular disease complications is also increased in patients with inflammatory diseases that affect the kidneys, such as vasculitis. Currently, there are no reliable biomarkers that will identify those patients with kidney disease that will go on to develop cardiovascular disease. This study will explore the potential of manganese-enhanced magnetic resonance imaging (MEMRI) to act as a biomarker of AKI and its cardiovascular and renal complications. An analogue of calcium, manganese is readily taken-up into viable cells where it increases T1 relaxivity. Preliminary data show rapid manganese uptake in the heart and kidneys of healthy subjects. The investigators propose to use MEMRI to demonstrate differences in renal and myocardial calcium handling in patients with acute insults (such as AKI, transplant rejection, donation or episodes of rejection or new vasculitis presentations) or improvements (such as transplantation). The investigators will also investigate whether these abnormalities reverse in those whose injury resolves or persist in those who clearly develop CKD, or who are at risk of future cardiovascular disease and CKD.

Research on the Effectiveness of Neurorehabilitation After Stroke

Stroke · Stroke Acute · Stroke with Hemiparesis

This clinical trial aims to investigate the effectiveness of a novel neurorehabilitation technology for treating stroke in adults. The study will evaluate a simulator that combines robotic orthosis, a non-invasive brain-computer interface (BCI), and a virtual reality (VR) display. The goal of this trial is to advance stroke rehabilitation by exploring the potential benefits of these cutting-edge technologies. Key Research Questions: Efficacy: Does the new simulator significantly improve arm function compared to standard rehabilitation techniques? BCI Technology: Which approach - motor imagery of only the paretic arm or both the paretic and healthy arm - yields greater functional improvements? VR Contribution: How does the integration of VR enhance rehabilitation outcomes? Safety and Tolerability: What potential side effects or adverse events may arise from using the new simulator? Participants who have suffered a stroke will undergo a standard rehabilitation course, during which 10-12 sessions will take place using the innovative simulator: a robotic device moves a patient's paralyzed arm at the command of a non-invasive brain-computer interface to perform a game task resembling real-life activities, augmented by a virtual reality display. Researchers will assess the impact of the new technology on arm function to determine its efficacy in promoting recovery.

Diagnosis and OutcoMes evaluAtIoN of Multicenter Patients With HFpEF Using Multimodality Imaging

Heart Failure, Diastolic · Multicenter Study

The incidence of Heart failure with preserved ejection fraction (HFpEF) in Heart failure patients increases rapidly. However, the current clinical awareness is insufficient, and the cardiac structural and functional injury are not well understood. It is difficult to recognize the subclinical changes of the cardiac in the early stage with conventional imaging techniques, and it is common to ignore the existence of the clinical alterations. This study aimed to investigate the cardiac features, early diagnosis and risk factors of HFpEF patients, based on the multi-modality (Magnetic resonance imaging- nuclear medicine imaging- echocardiography) imaging and multicenter study, combined with large data and artificial intelligence. This study will provide deep insights into the HFpEF in multicenter population.

Efficacy of Adenosine as Compared to Verapamil in Paroxysmal Supraventricular Tachycardia (pSVT) Patients

Supraventricular Tachycardia (SVtach)

Supraventricular tachycardia (SVT) is a term widely used to describe tachycardial dysrhythmias, paroxysmal SVT (PSVT) is a narrow term including only AV nodal re-entrant tachycardia (AVNRT) and atrioventricular re-entrant tachycardia (AVRT), both of which can cause discomfort and, in some cases, life-threatening symptoms. Usually Carotid sinus massage is done to lower the pulse rate and after the standard time specific verapamil dose is administered. In this study after carotid sinus massage Conventional Valsalva or modified Valsalva maneuver will be randomly applied. In case, the normal sinus rhythm (NSR) is not achieved then verapamil of or adenosine dose will be administered to the patients after after taking the consent.

The Preeclampsia Registry

Preeclampsia · Eclampsia · HELLP Syndrome

The purpose of The Preeclampsia Registry is to collect and store medical and other information from women who have been medically diagnosed with preeclampsia or a related hypertensive (high blood pressure) disorder of pregnancy such as eclampsia or HELLP syndrome, their family members, and women who have not had preeclampsia to serve as controls. Information from participants will be used for medical research to try to understand why preeclampsia occurs, how to predict it better, and to develop experimental clinical trials of new treatments. The Registry will consist of a web-based survey and mechanism for collecting and reviewing medical records. This data will be utilized for immediate investigator-driven cross-sectional research projects (after proposal review by the Registry's scientific advisory board and as directed by the PI). Participants may also choose to be contacted regarding possible participation in future studies, about providing a biospecimen, as well as investigator-driven clinical trials. The Registry is anticipated to exist long-term and to serve as a foundation of participants from which to draw for studies of preeclampsia, anticipated to evolve as our scientific understanding of preeclampsia evolves.

Early Motor-Cognitive Integrative Training on Cognitive and Motor Performance in Patients With Aneurysmal Subarachnoid Hemorrhage

Subarachnoid Aneurysm Hemorrhage

Despite its lower incidence rate within the stroke population and tendency to affect younger individuals, SAH carries the highest risk of PSCI. The neural mechanisms underlying these cognitive deficits remain poorly understood, but potential factors include treatment approaches, underlying disease pathophysiology, post-disease complications, or alterations in neural connectivity\[10\]. Previous literature indicates that cognitive deficits in SAH primarily manifest in areas such as visuospatial skill, verbal memory language abilities (including verbal comprehension, verbal fluency, abstract language), executive function (working memory) and attention. These impairments significantly impact patients' ability to perform ADL independently and return to work, despite motor function recovery.

Diagnostic Innovations in Glaucoma Study

Primary Open Angle Glaucoma · Myopia

The overarching goal of our research study is to evaluate changes in visual function and optic nerve topography (the structure of the back of the eye) in patients with glaucoma (increased susceptibility to pressure inside the eye that can cause loss of vision) or those with an increased risk of developing the disease. The purpose of this study is to determine the best methods for detecting the presence or progression (worsening over time) of glaucoma in patients with and without myopia and its effects on daily and visual function and quality of life. With several sources of NIH and foundation funding over the last twenty years we have designed a robust research protocol to address the most challenging aspects of glaucoma management. The most recent focus of this research is 1) to improve our ability to detect open angle glaucoma in individuals with myopia and in individuals of European and African descent, 2) to determine whether monitoring of the retinal vasculature with new optical imaging instruments can improve glaucoma management and elucidate the pathophysiology of the disease, and 3) to differentiate between age-related changes and glaucomatous progression. The grants supporting this project include 3 NIH funded studies, 1) the University of California, San Diego UCSD -based "Diagnostic Innovations in Glaucoma Study" (DIGS funded since 1995): 2) the "African Descent and Glaucoma Evaluation Study" (ADAGES funded since 2002), 3) the Brightfocus Foundation National Glaucoma Research Program and 4) the UCSD-based "Diagnosis and Monitoring of Glaucoma with Optical Coherence Tomography Angiography" (funded since 2018). The ADAGES is a multi-center study with data collection also conducted at 2 other academic sites, the University of Alabama at Birmingham, and Columbia University. Enrolled healthy participants, glaucoma suspects and glaucoma patients are generally asked to return for two or more visits a year for several years. We then analyze whether the glaucoma patients are progressing and what factors influence their glaucoma status compared to healthy subjects and individuals suspected of having glaucoma.
