Myositis/myasthenia gravis caused by immune checkpoint inhibition: A report of two cases and a brief review of the literature.

Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy by enhancing the ability of the immune system to combat malignancies. Nivolumab and cemiplimab, monoclonal antibodies targeting programmed cell death protein 1, have exhibited notable therapeutic efficacy; however, they are associated with immune-related adverse events (irAEs). The present study describes the cases of 2 patients, a 71-year-old male with metastatic esophageal adenocarcinoma and a 66-year-old female with metastatic squamous cell carcinoma who developed acute/subacute onset rapidly progressive myositis/myasthenia gravis (MG) following treatment with nivolumab and cemiplimab.

A generalized Hosmer-Lemeshow goodness-of-fit test for a family of generalized linear models.

Unlabelled: Generalized linear models (GLMs) are very widely used, but formal goodness-of-fit (GOF) tests for the overall fit of the model seem to be in wide use only for certain classes of GLMs. We develop and apply a new goodness-of-fit test, similar to the well-known and commonly used Hosmer-Lemeshow (HL) test, that can be used with a wide variety of GLMs. The test statistic is a variant of the HL statistic, but we rigorously derive an asymptotically correct sampling distribution using methods of Stute and Zhu (Scand J Stat 29(3):535-545, 2002) and demonstrate its consistency.

Formulation and Characterization of Bioactive Agent Containing Nanodisks.

The term nanodisk refers to a discrete type of nanoparticle comprised of a bilayer forming lipid, a scaffold protein, and an integrated bioactive agent. Nanodisks are organized as a disk-shaped lipid bilayer whose perimeter is circumscribed by the scaffold protein, usually a member of the exchangeable apolipoprotein family. Numerous hydrophobic bioactive agents have been efficiently solubilized in nanodisks by their integration into the hydrophobic milieu of the particle's lipid bilayer, yielding a largely homogenous population of particles in the range of 10-20 nm in diameter.
