A Taxonomy Of Childhood Pedal Cyclist Injuries From Latent Class Analysis: Associations With Factors Pertinent To Prevention, Joseph Piatt

Department of Neurosurgery Faculty Papers

Background: Studies of pedal cyclist injuries have largely focused on individual injury categories, but every region of the cyclist's body is exposed to potential trauma. Real-world injury patterns can be complex, and isolated injuries to one body part are uncommon among casualties requiring hospitalization. Latent class analysis (LCA) may identify important patterns in heterogeneous samples of qualitative data.

Methods: Data were taken from the Trauma Quality Improvement Program of the American College of Surgeons for 2017. Inclusion criteria were age 18 years or less and an external cause of injury code for pedal cyclist. Injuries were characterized by Abbreviated Injury …

Adipose Tissue Uses In Peripheral Nerve Surgery, Allison Podsednik, Raysa Cabrejo, Joseph Rosen

School of Medicine Publications and Presentations

Currently, many different techniques exist for the surgical repair of peripheral nerves. The degree of injury dictates the repair and, depending on the defect or injury of the peripheral nerve, plastic surgeons can perform nerve repairs, grafts, and transfers. All the previously listed techniques are routinely performed in human patients, but a novel addition to these peripheral nerve surgeries involves concomitant fat grafting to the repair site at the time of surgery. Fat grafting provides adipose-derived stem cells to the injury site. Though fat grafting is performed as an adjunct to some peripheral nerve surgeries, there is no clear evidence …

Upregulation Of Cd36, A Fatty Acid Translocase, Promotes Colorectal Cancer Metastasis By Increasing Mmp28 And Decreasing E-Cadherin Expression, James Drury, Piotr G. Rychahou, Courtney O. Kelson, Mariah E. Geisen, Yuanyuan Wu, Daheng He, Chi Wang, Eun Y. Lee, B. Mark Evers, Yekaterina Y. Zaytseva

Surgery Faculty Publications

Altered fatty acid metabolism continues to be an attractive target for therapeutic intervention in cancer. We previously found that colorectal cancer (CRC) cells with a higher metastatic potential express a higher level of fatty acid translocase (CD36). However, the role of CD36 in CRC metastasis has not been studied. Here, we demonstrate that high expression of CD36 promotes invasion of CRC cells. Consistently, CD36 promoted lung metastasis in the tail vein model and GI metastasis in the cecum injection model. RNA-Seq analysis of CRC cells with altered expression of CD36 revealed an association between high expression of CD36 and upregulation …

Enhancing Precision In Bioprinting Utilizing Fuzzy Systems, Ashkan Sedigh, Dayna Dipiero, Kristy M. Shine, Ryan E. Tomlinson

Department of Orthopaedic Surgery Faculty Papers

Bioprinting facilitates the generation of complex, three-dimensional (3D), cell-based constructs for a variety of applications. Although multiple bioprinting technologies have been developed, extrusion-based systems have become the dominant technology due to the diversity of substrate materials (i.e. bioinks) that can be accommodated, either individually or in combination. Each bioink has unique material properties and extrusion characteristics that limit bioprinting precision, particularly when generating identically shaped constructs from different bioinks. Here, we aimed to achieve high precision (i.e. repeatability) across samples by generating bioink-specific printing parameters using a systematic approach. We hypothesized that a Fuzzy system could be used as a …

Loss Of Smad4 Is Associated With Poor Tumor Immunogenicity And Reduced Pd-L1 Expression In Pancreatic Cancer, Daniel R. Principe, Patrick W. Underwood, Sandeep Kumar, Kaytlin E. Timbers, Regina M. Koch, Jose G. Trevino, Hidayatullah G. Munshi, Ajay Rana

Surgery Publications

Transforming Growth Factor β (TGFβ) is a key mediator of immune evasion in pancreatic ductal adenocarcinoma (PDAC), and the addition of TGFβ inhibitors in select immunotherapy regimens shows early promise. Though the TGFβ target SMAD4 is deleted in approximately 55% of PDAC tumors, the effects of SMAD4 loss on tumor immunity have yet to be fully explored. Using a combination of genomic databases and PDAC specimens, we found that tumors with loss of SMAD4 have a comparatively poor T-cell infiltrate. SMAD4 loss was also associated with a reduction in several chemokines with known roles in T-cell recruitment, which was recapitulated …

Current And Novel Neuroregenerative Therapies, Arrin Brooks

Theses, Dissertations and Capstones

Underlying the physical and cognitive deficits consequent of many neuropathologies is one common factor, the loss of neurons. While neurodegenerative diseases, stroke, and traumatic brain injury arise from a variety of etiologies, they all ultimately result in injury and/or death of neuronal cells and concomitant functional deficits. In the present work we primarily focus on current and potential treatments for localized lesions, particularly those in the striatum of Parkinson’s disease (PD) or the cortex as in stroke. First, we discuss a new surgical technique for deep brain stimulator (DBS) placement, as DBS is a mainstay treatment for movement disorders including …
