Dedifferentiation of a Chondrosarcoma of the Larynx: A Case Report.

Background: Chondrosarcomas of the larynx, relatively rare tumors with low grade pathology in approximately 95% of cases, can most often be managed with conservation laryngeal procedures. Dedifferentiated chondrosarcomas are much more rare and aggressive requiring more aggressive surgical extirpation.

Methods: A patient underwent three debulking procedures for a laryngeal chondrosarcoma Grade I/II histologically over a 2.

Antifouling Immunomodulatory Copolymer Architectures That Inhibit the Fibrosis of Implants.

Immune reactions to medical implants often lead to encapsulation by fibrotic tissue and impaired device function. This process is thought to initiate by protein adsorption, which enables immune cells to attach and mount an inflammatory response. Previously, several antifibrotic materials have been either designed to reduce protein adsorption or discovered via high-throughput screens (HTS) to favorably regulate inflammation.

Zwitterionic Polymer-Functionalized Lipid Nanoparticles for the Nebulized Delivery of mRNA.

Lipid nanoparticles (LNPs) have great potential to enable inhaled delivery of mRNA to treat pulmonary diseases. However, this potential has been limited by the challenge of nebulizing the LNPs. Nebulization of LNPs can cause LNPs to aggregate and release encapsulated mRNA, limiting their delivery efficacy.

Longitudinal Pain Management Claims in Maryland: Implications.

The study is a longitudinal review of pain management claims filed in the state of Maryland. Adverse outcomes associated with pain-related claims are often severe and include death, brain damage, and back and spinal cord sequelae. There is a lot to be learned from past experiences, identified in closed pain management claims, specifically on how to improve patient education, outcomes, quality, and safety.

Therapeutic silencing in TREM2 cardiac macrophages suppresses atrial fibrillation.

Atrial fibrillation (AFib) and the risk of its lethal complications are propelled by fibrosis, which induces electrical heterogeneity and gives rise to reentry circuits. Atrial TREM2 macrophages secrete osteopontin (encoded by ), a matricellular signaling protein that engenders fibrosis and AFib. Here we show that silencing in TREM2 cardiac macrophages with an antibody-siRNA conjugate reduces atrial fibrosis and suppresses AFib in mice, thus offering a new immunotherapy for the most common arrhythmia.
