Multiomic molecular patterns of lipid dysregulation in a subphenotype of sepsis with higher shock incidence and mortality.

Background: Lipids play a critical role in defense against sepsis. We sought to investigate gene expression and lipidomic patterns of lipid dysregulation in sepsis.

Methods: Data from four adult sepsis studies were analyzed and findings were investigated in two external datasets.

Predicting adaptive immune receptor specificities by machine learning is a data generation problem.

Determining the specificity of adaptive immune receptors-B cell receptors (BCRs), their secreted form antibodies, and T cell receptors (TCRs)-is critical for understanding immune responses and advancing immunotherapy and drug discovery. Immune receptors exhibit extensive diversity in their variable domains, enabling them to interact with a plethora of antigens. Despite the significant progress made by AI tools such as AlphaFold in predicting protein structures, challenges remain in accurately modeling the structure and specificity of immune receptors, primarily due to the limited availability of high-quality crystal structures and the complexity of immune receptor-antigen interactions.

The physiological landscape and specificity of antibody repertoires are consolidated by multiple immunizations.

Diverse antibody repertoires spanning multiple lymphoid organs (i.e., bone marrow, spleen, lymph nodes) form the foundation of protective humoral immunity.

A Novel Intersection: Cytomegalovirus Gastritis Following Cemiplimab and Talimogene Laherparepvec in a Patient With Advanced Cutaneous Squamous Cell Carcinoma.

Cytomegalovirus (CMV) reactivation is a rare complication in patients treated with immune checkpoint inhibitors (ICIs), typically occurring after immunosuppressive therapy for immune-related adverse events (irAEs). Here, we report a unique case of severe CMV gastritis in a patient receiving cemiplimab, an anti-PD-1 antibody, and talimogene laherparepvec (T-VEC), an oncolytic virus, without prior irAEs or immunosuppressive treatment. A 63-year-old man with advanced cutaneous squamous cell carcinoma received cemiplimab for one year and a single T-VEC injection for recurrent disease.

Survey of Utilization of Weightbearing Computed Tomography Within AOFAS Membership.

Background: Weightbearing computed tomography (WBCT) has been increasingly employed to evaluate and treat patients with varied pathologies such as progressive collapsing foot deformity (PCFD), posttraumatic deformity, hallux valgus, ankle arthritis, Charcot arthropathy, lisfranc, and syndesmosis injuries. However, little is known regarding its overall availability to foot and ankle providers and how it is being used in clinical practice. The goal of this study is to assess the utilization of WBCT among AOFAS members, identify the indications for use in clinical practice and potential barriers for implementation.
