Putting It All Together: The Roles of Ribosomal Proteins in Nucleolar Stages of 60S Ribosomal Assembly in the Yeast .

Here we review the functions of ribosomal proteins (RPs) in the nucleolar stages of large ribosomal subunit assembly in the yeast . We summarize the effects of depleting RPs on pre-rRNA processing and turnover, on the assembly of other RPs, and on the entry and exit of assembly factors (AFs). These results are interpreted in light of recent near-atomic-resolution cryo-EM structures of multiple assembly intermediates.

Impact of Atopic Status on Clinical Presentation and Treatment Response in Pediatric Patients With Eosinophilic Esophagitis.

Background: Nearly 80% of patients with eosinophilic esophagitis (EoE) have coexisting atopic disease, yet a subset do not. It is unclear if this lack of atopy impacts presentation or response to therapy.

Objectives: To characterize the presentation and response to therapy in atopic versus nonatopic pediatric patients with EoE.

Tofacitinib in Pediatric Ulcerative Colitis: A Retrospective Multicenter Experience.

Background: Tofacitinib has recently been approved for treatment of moderate-to-severe ulcerative colitis (UC) in adults, yet pediatric data are limited. This international multicenter study describes the effectiveness and safety of tofacitinib in pediatric UC.

Methods: This is a retrospective review of children diagnosed with UC treated with tofacitinib from 16 pediatric centers internationally.

Potential for Glove Risk Amplification via Direct Physical, Chemical, and Microbiological Contamination.

This review focuses on the potential direct physical, chemical, and microbiological contamination from disposable gloves when utilized in food environments, inclusive of the risks posed to food products as well as worker safety. Unrecognized problems endemic to glove manufacturing were magnified during the COVID-19 pandemic due to high demand, increased focus on PPE performance, availability, supply chain instability, and labor shortages. Multiple evidence-based reports of contamination, toxicity, illness, deaths, and related regulatory action linked to contaminated gloves in food and healthcare have highlighted problems indicative of systemic glove industry shortcomings.

Comparison of Tuberculin Skin Testing and Interferon-γ Release Assays in Predicting Tuberculosis Disease.

Importance: Elimination of tuberculosis (TB) disease in the US hinges on the ability of tests to detect individual risk of developing disease to inform prevention. The relative performance of 3 available TB tests-the tuberculin skin test (TST) and 2 interferon-γ release assays (IGRAs; QuantiFERON-TB Gold In-Tube [QFT-GIT] and SPOT.TB [TSPOT])-in predicting TB disease development in the US remains unknown.
