The objective of this research study is to identify brain biomarkers using MRI scans that can predict an individual's response to Deep Brain Stimulation (DBS). A total of 55 participants with Parkinson's Disease planning to undergo DBS will be recruited from MUSC's Clinical DBS Program. Participants will undergo two visits which include a 2.5-hour pre-DBS questionnaire and MRI scanning visit, and a 3.5-hour post-DBS cognitive assessment visit. In addition control participants without Parkinson's Disease will be recruited to undergo MRI scanning and cognitive assessments.

This study is for patients with cancer and is being done to see if blood samples from patients with and without certain types of cancer help researchers develop a future blood test for use in detecting cancer early.

This study is enrolling participants who are already implanted with a S-ICD device (Subcutaneous Implantable Cardioverter Defibrillator, which is a device designed to monitor heart rhythms and deliver a shock to the heart to stop life threatening heart rhythms), and are undergoing a routine outpatient clinic follow up appointment to have their S-ICD checked. The aim of the study is to see if a feature in the device can recognize muscle movement and differentiate movement from irregular heart signals. The study involves doing some simple arm exercises while collecting device data, both with this feature turn on and then with it turned off. Participants will be randomized to either have the feature turned on or off initially then it will be programmed the alternative way and the same exercise testing will be repeated. The study will involve just one visit.

The study is to evaluate real world usage of the ENROUTE® Transcarotid Stent System when used with the ENROUTE® Transcarotid Neuroprotection System in patients with significant carotid artery disease who are at standard risk for adverse events from carotid endarterectomy (CEA). The devices used in the study are not investigational and have been approved for use by the Food and Drug Administration (FDA).

The purpose of this study is determine the optimal dose, efficacy and safety of an investigational drug (a new drug not yet approved by the U.S. Food and Drug Administration) in adults with Advanced Systemic Mastocytosis. The investigational drug is known as CGT9486 and will be taken daily orally. Participation in the study is expected to be approximately 6 years.

This study's objective is to determine if electrical stimulation can safely reduced atrial fibrillation, which is an abnormal heart rhythm that begins in the top chambers of the heart. Electrical stimulation will be delivered to the wrists or in the ear. Participation will last about 6 weeks and require 3 clinic visits. Participants will be asked to wear a heart monitor and patch to monitor the heart rate and rhythm, keep a diary to collect information on atrial fibrillation, undergo randomization (being randomly assigned, like drawing straws) and use the study device per randomization assignment. Participants are randomized in a 1:1:1 fashion to a wrist worn study device, an ear piece study device or a sham wrist worn study device. A sham device looks like the real wrist worn device but does not deliver any electrical stimulation.

This study will evaluate the safety and effectiveness of fazirsiran (investigational drug) compared with placebo (an inactive substance) in patients with alpha-1 antitrypsin deficiency associated liver disease (AATD-LD). If eligible, subjects will be randomized (assigned to a group by chance) to receive either fazirsiran or placebo to be administered subcutaneously (an injection under the skin). Subjects will be treated on Day 1, at Week 4, and then every 12 weeks for 196 weeks. Subjects will be followed for 6 months after their last dose of study drug or placebo for a total study duration of approximately 230 weeks (including 10 weeks of the screening period which is the time needed to assess if a subject is eligible for the study).

Following the study Entry Visit, subjects will return at Week 4,
Week 12, and every 12 weeks thereafter. Study visits will continue
for up to 6 years or until the subject prematurely discontinues study
treatment due to an adverse event or other reason, inhaled treprostinil
becomes commercially available for IPF in the region in which the
study is conducted, or the study is discontinued by the Sponsor
(whichever is sooner). Subjects will also be contacted by telephone or
email at least weekly until Week 12 and monthly thereafter in
between study visits to discuss study drug titration, assess study drug
tolerability, monitor adverse event, document changes to concomitant
medications, and remind subjects to bring in all study drug and a
device to their next clinic visit.

This study evaluates whether non-cigarette tobacco products (e-cigarettes) can help smokers quit smoking as compared to traditional quit methods (nicotine replacement therapy or varenicline/Chantix). Participants in this study will be randomly assigned to one of two groups, then will have a choice between the offered products of that group. Participants in the e-cigarette group will have a choice of e-cigarette brand and flavor. Participants in the medication group will have choice between nicotine replacement therapy (patches and lozenges) or varenicline, also known as Chantix. Participation will last 6 months and will include weekly phone calls for the initial 7-weeks plus a 11-week phone call and a 6-month follow-up visit. Participants will also complete electronic daily diaries during the first 7-weeks.

The purpose of the research is to test out a combined treatment for depression where we stimulate a nerve in the ear while at the same time stimulating the brain with magnets. These treatments are called transcutaneous (through the skin) auricular (ear) vagus nerve stimulation (taVNS) and transcranial (through the skull) magnetic stimulation (TMS). For patients who already have a cervical VNS device, we will not change their treatment and will use this in place of the taVNS. We think this combined method might treat depressive symptoms better than either alone. This study is in person at the Institute of Psychiatry in downtown Charleston on the MUSC campus. First, patients will have a screening session and then will have 6 treatment days total where they will receive either VNS treatment alone, TMS treatment alone, or both at the same time. The treatment they start with will be randomized, and they will have 2 treatment days of each combination.
