Effect of Eribulin With or Without Pembrolizumab on Progression-Free Survival for Patients With Hormone Receptor-Positive, ERBB2-Negative Metastatic Breast Cancer: A Randomized Clinical Trial.

Importance: Prior studies have shown that only a small proportion of patients with hormone receptor (HR)-positive metastatic breast cancer (MBC) experience benefit from programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors given as monotherapy. There are data suggesting that activity may be greater with combination strategies.

Objective: To compare the efficacy of eribulin plus pembrolizumab vs eribulin alone in patients with HR-positive, ERBB2 (formerly HER2)-negative MBC.

Expedient treatment of a collodion baby.

Only ~270 cases of collodion babies have been reported in the literature since 1892. As the name suggests, the term "collodion baby" refers to a phenotype that can be characterized by a yellow, shiny, tight parchment-like membrane stretched over the skin. Although the collodion membrane is only an evanescent condition of the newborn, neonatal complications can occur in 45% of all collodion babies, leading to a mortality rate of ~11% in the first few weeks of life.

Atypical Clinical and Diagnostic Features in Ménétrier's Disease in a Child.

Ménétrier's disease is one of the rarest protein-losing gastropathies in childhood. It is characterized clinically by non-specific gastrointestinal symptoms and edema, biochemically by hypoalbuminemia, and pathologically by enlarged gastric folds. In adults, this disease can be devastating with significant morbidity and mortality.

Identification of phosphorylation-induced changes in vimentin intermediate filaments by site-directed spin labeling and electron paramagnetic resonance.

Phosphorylation drives the disassembly of the vimentin intermediate filament (IF) cytoskeleton at mitosis. Chromatographic analysis has suggested that phosphorylation produces a soluble vimentin tetramer, but little has been determined about the structural changes that are caused by phosphorylation or the structure of the resulting tetramer. In this study, site-directed spin labeling and electron paramagnetic resonance (SDSL-EPR) were used to examine the structural changes resulting from protein kinase A phosphorylation of vimentin IFs in vitro.

Identifying the role of specific motifs in the lens fiber cell specific intermediate filament phakosin.

Purpose: Phakosin and filensin are lens fiber cell-specific intermediate filament (IF) proteins. Unlike every other cytoplasmic IF protein, they assemble into a beaded filament (BF) rather than an IF. Why the lens fiber cell requires two unique IF proteins and why and how they assemble into a structure other than an IF are unknown.
