Locked Dimerized CXCL12 Exerts Radiosensitizing Effects in Head and Neck Cancer.

Background: Head and neck squamous cell carcinoma (HNSCC) presents significant treatment challenges, particularly in cases unrelated to human papillomavirus (HPV). The chemokine receptor CXCR4, interacting with its ligand CXCL12, plays a crucial role in tumor proliferation, metastasis, and treatment resistance. This study explores the therapeutic potential of engineered monomeric and dimerized CXCL12 variants (CXCL12 and CXCL12, respectively) in HNSCC and evaluates potential additive effects when combined with radiation therapy.

Exploratory Pilot Study Engages Community Health Workers to Test Drone-Based Package Delivery System for Personal Protective Equipment in High-Risk Appalachia Population.

During the COVID-19 pandemic, high-risk clients' and caregivers' access to essential personal protective equipment (PPE) was limited especially in many remote areas of Appalachia. A multidisciplinary team of community and university partners explored how to coordinate the use of community health workers (CHWs) and drone technologies to increase access to PPE in rural and remote Appalachian regions. CHWs recruited 10 Homeplace clients in an exploratory study of drone-based package delivery of PPE to assess importance and effectiveness of PPE self-efficacy related to PPE use, use of PPE, and ease and acceptability of drone delivery (following delivery only).

Enhancing healthcare accessibility through telehealth for justice impacted individuals.

Telehealth is a great tool that makes accessing healthcare easier for those incarcerated and can help with reentry into the the community. Justice impacted individuals face many hardships including adverse health outcomes which can be mitigated through access to telehealth services and providers. During the federally recognized COVID-19 pandemic the need for accessible healthcare was exacerbated and telehealth use surged.

Type I interferon signaling promotes radioresistance in head and neck cancer.

Despite the promise of concurrent radiotherapy (RT) and immunotherapy in head and neck cancer (HNC), multiple randomized trials of this combination have had disappointing results. To evaluate potential immunologic mechanisms of RT resistance, we compared pre-treatment HNCs that developed RT resistance to a matched cohort that achieved curative status. Gene set enrichment analysis demonstrated that a pre-treatment pro-immunogenic tumor microenvironment (TME), including type II interferon [interferon gamma (IFNγ)] and tumor necrosis factor alpha (TNFα) signaling, predicted cure while type I interferon [interferon alpha (IFNα)] enrichment was associated with an immunosuppressive TME found in tumors that went on to recur.
