Common Cast Complications, Jessica A Mcgraw-Heinrich, Jon C Wall, Scott B Rosenfeld

Faculty, Staff and Students Publications

Complications can arise from the application, wear, and removal of casts and splints. This text reviews common complications, risk factors, and prevention strategies while exploring the medical-legal implications of these complications. Being aware of common pitfalls can help reduce risk and promote optimal patient outcomes.

Key concepts: (1)Proper and judicious casting and splinting techniques are critical to prevent complications.(2)Thermal injuries can occur due to excessive curing heat and cast saw burns.(3)Poor cast molding can lead to skin sores and loss of fracture reduction.(4)Patients should be comfortable in their cast, and uncontrolled pain warrants investigation.

Outcomes Of Suprapatellar Intramedullary Nail Fixation Of Tibial Shaft Fractures In Skeletally Immature Patients, Carlos D Pargas-Colina, Tori J Coble, Sara E Davis, David D Spence, Jonathan K Rowland, Derek M Kelly, Benjamin W Sheffer

Faculty, Staff and Students Publications

Background: Tibial shaft fractures in children require individualized treatment approaches, including elastic nails, plates and screws, intramedullary rigid nails (IMN), and external fixators, with selection based on fracture characteristics and patient factors. IMN risks damaging the physis, but can provide enhanced stability and immediate weight bearing. While both infrapatellar and suprapatellar approaches exist for IMN placement, studies in adults have demonstrated that the suprapatellar approach offers higher patient satisfaction, less anterior knee pain, and lower radiation exposure. However, there is a lack of data on IMN for pediatric tibial fractures.

Methods: This single-center, retrospective cohort study analyzed patients aged 11-16 …

Age-related macular degeneration (AMD) is a leading cause of vision loss, driven by retinal pigment epithelium (RPE) and photoreceptor degeneration. A key feature is drusen accumulation between the RPE and Bruch's membrane. In intermediate AMD, hyperreflective foci (HRF)-bright intraretinal lesions visible on optical coherence tomography (OCT) imaging-serve as biomarkers of disease progression. To study HRF mechanisms, we generated induced pluripotent stem cell (iPSC) lines from an AMD patient with HRF overlying drusen (RFSC4) and their unaffected sibling (RFSC3). These iPSC models offer a platform to explore disease mechanisms and develop therapies for AMD.

The nervous system has a pivotal role in cancer biology, and pathological investigations have linked intratumoural nerve density to metastasis1. However, the precise impact of cancer-associated neurons and the communication channels at the nerve–cancer interface remain poorly understood. Previous cancer denervation models in rodents and humans have highlighted robust cancer dependency on nerves, but the underlying mechanisms that drive nerve-mediated cancer aggressivity remain unknown2,3. Here we show that cancer-associated neurons enhance cancer metabolic plasticity by transferring mitochondria to cancer cells. Breast cancer denervation and nerve–cancer coculture models confirmed that neurons significantly improve tumour energetics. …

Faculty, Staff and Students Publications

Regeneration of dentin and odontoblasts from dental pulp progenitor cells is essential for the maintenance of permanent tooth. However, the in vivo identity of endogenous pulp progenitor cells and how they contribute to reparative dentinogenesis remain elusive. Here we show that comparative single-cell analysis of pulp cells before and after molar eruption reveal that endogenous pulp progenitor cells are enriched in coronal papilla-like cells with Mx1-Cre and Cxcl12–GFP expression. Further, lineage tracing and fluorescence-activated cell sorting analysis indicated that Mx1-labeled (Mx1+) pulp cells include long-term repopulating progenitor cells with higher expression of stem cell markers. Notably, …

Using functional magnetic resonance imaging (fMRI), symptoms of posttraumatic stress disorder (PTSD) have been associated with aberrations in brain networks in the absence of a given cognitive demand or task, called resting-state networks. Prior work has focused on disruption in the static functional connectivity (FC) among specific regions constrained by a priori hypotheses. However, dynamic FC, an approach that examines brain network characteristics over time, may provide a more sensitive measure to understand the network properties underlying dysfunction in PTSD. Further, using a data-driven analytic approach may reveal the contribution of other larger network disturbances beyond those revealed by hypothesis-driven …
