8 Clinical Trials for Various Conditions
Breast implants, either cosmetic or reconstructive, are among the most common procedures performed by plastic surgeons. Bacterial infections or biofilms are implicated in the majority of breast implant complications including infection requiring explantation, capsular contracture (CC), and/or breast-implant associated anaplastic large cell lymphoma (BIA-ALCL). The research team, which has already extensively characterized bacterial pathogenesis in the urinary tract and designed non-antibiotic therapeutics to reduce the incidence of catheter-associated urinary tract infections (CAUTIs), and proposal will study bacteria-breast implant interactions and explore further the impact of the breast microbiome. The proposed research provides a greater understanding of which bacteria can colonize breast implants, their source, and how effective antibiotic pocket irrigation is at eliminating them, and begins to examine the mechanisms by which bacteria bind and colonize the implant surface. These insights will set the groundwork for developing new therapeutic agents that can disrupt the binding of certain bacteria to breast implants. Strategies that minimize problems bacteria can cause, while avoiding antibiotics, will reduce bacteria-related implant complications, limit antibiotic-related side effects, and reduce bacterial resistance.
The most common tissue expander-related infections are from Staphylococcus and Pseudomonas species. In addition, from breast tissue microbiome studies, Staphylococcus and Pseudomonas show variable abundance across samples. The investigator hypothesizes that participants undergoing mastectomy with high initial abundance of Staphylococcus and/or Pseudomonas are more likely to develop subsequent tissue expander-related infections from these respective organisms.
This is a prospective, histologic analysis of biopsied tissue obtained from participants who have undergone a pre-pectoral breast reconstruction or augmentation surgery with expander placement and AlloMend® Acellular Dermal Matrix. AlloMend® Acellular Dermal Matrix graft incorporation with surrounding native soft tissue using histological assays characterizing host cell infiltration, neovascularization, inflammation, and host replacement of ADM collagen will be studied.
Surgical mesh products, particularly acellular dermal matrices (ADM), are now used by the majority of plastic surgeons to assist with the nearly 100,000 prosthetic breast reconstruction procedures in the United States, despite never being approved by Food and Drug Administration (FDA) for this indication. As surgeons transition to placing breast implants above the chest muscle (pre-pectoral), there has been an increasing reliance on these often expensive mesh products without robust evidence to understand their risks and benefits. Our pilot study is a randomized multi-center trial to evaluate surgical mesh assistance in pre-pectoral tissue expander to breast implant reconstruction to address vital questions for women's public health.
Bacterial biofilms cause implant failures, chronic inflammation, and immune polarization. The study investigates the possible role of bacterial biofilm as a factor in the etiology of Breast Implant Illness. Three patient cohorts will be studied (A) Subjects with breast implant with BII manifestations (B) Subjects with breast implants without BII manifestations (C) Subjects without breast implants who underwent breast surgery procedure. Blood, surgically discarded tissue, implants, and associated capsules will be collected through this protocol.
The purpose of this registry study is to create a database-a collection of information-for better understanding T-cell lymphoma. Researchers will use the information from this database to learn more about how to improve outcomes for people with T-cell lymphoma.
This study will look at the rate of infections developed by subjects comparing the use of disposable draping systems versus reusable draping systems in the operating room.
The goal of this clinical trial is to learn whether showering with surgical drain tubes in place after first stage breast reconstruction causes increased risk of infection. The main questions it aims to answer are: * Is there an increased risk of infection/complications with showering 48 hours after drain tubes are in place * Does showering after 48 hours with drain tubes in place affect quality of life.
