This study is being conducted in women who are at least 22 years old,+ and will be undergoing either a unilateral or bilateral mastectomy with immediate two-stage post-mastectomy alloplastic prepectoral breast reconstruction (initial insertion of a tissue expander on top of the chest wall muscle followed by change-over to a breast implant after a period of tissue expander inflation).

The purpose of this research study is to evaluate the safety and effectiveness of the Melodi Matrix. .

The Melodi Matrix is an absorbable mesh that contains antibacterial agents (medicines that fight infections caused by bacteria) and is wrapped around tissue expanders before being implanted. After approximately 9 weeks, the mesh will fully absorb into the body.

The primary objective of this study is to demonstrate the safety and effective use of Stryker's PEEK Customized Implants in patients receiving craniofacial (head and facial) surgery. Other objectives include using a CT scan to assist surgeons with providing a solution to complex and simple reconstruction challenges and reducing them to a single or two-stage procedure, thereby minimizing the overall surgery time and limiting the number of surgeries. Patient questionnaires and health information will be used during the study to demonstrate the safety and effectiveness of the implants. We will be enrolling ages 4 - 75 years old.

For this study, we are recruiting 54 individuals with Parkinson's Disease and Freezing of Gait (FOG) who are planning to undergo Deep Brain Stimulation (DBS). The objective of this study is to better understand the FOG response to DBS. Prior to DBS study participants will undergo a MRI scan, behavioral assessment related to walking, a cognitive evaluation, and assessment of other Parkinson's disease symptoms. Following DBS participants will repeat these assessments at multiple timepoints over the period of one year. Overall, participants will complete a total of 7 visits over a period of approximately 1 year.

Assess the safety and effectiveness of the ASG device in
the treatment of lesions involving the ascending aorta and
aortic arch.

This study is for participants who have tricuspid regurgitation, a condition in which your heart's tricuspid valve does not close tightly which causes blood to flow backwards in the incorrect direction. This condition increases the workload on the heart and if left untreated, it can increase the risk of worsening heart failure. In this study, a device called the VDyne Transcatheter Tricuspid Replacement System will be used to treat the tricuspid regurgitation. The VDyne Transcatheter Tricsupid Replacement System is an investigational device meaning it has not been approved for commercial use by the US Food and Drug Administration (FDA). In this study all eligible participants will be treated with the device.

Participation in this study will last about 5 years and involve up to 13 visits. Study related procedures include a right heart catheterization (test to measure the pressures in the heart), echocardiograms (ultrasound test of heart), electrocardiogram or ECG (test of the heart's electrical system) blood work, questionnaires, hall walk test, and physical exam.

There are risks associated with this study including potential risks with the device, implant procedure and study related procedures. There is also the risk of loss of confidentiality. The study may or may not benefit you but the information learned may benefit others with this condition in the future.

The purpose of this study is to better understand how surgical factors affect the length of the vagina after pelvic surgery. This will be accomplished by measuring the length of the vagina during routine surgical steps as well as at the postoperative visit. This information will be used to help continue improving pelvic surgical technique.

While blood clots after major cancer surgery are common and harmful to patients, the medications available to decrease blood clot risk are seldom used despite the recommendation of multiple professional medical societies. The reasons why these medications are seldom prescribed is not well understood. We aim to characterize barriers and facilitators to extended blood clot prophylaxis guideline adherence as perceived by stakeholders via interviews with a diverse group of patients and surgeons at hospitals within the MUSC Health system that routinely perform cancer surgery. These findings will inform educational interventions to improve the use of guideline concordant care and mitigate observed disparities in cancer care.
