Co-Circulation of 2 Oropouche Virus Lineages during Outbreak, Amazon Region of Peru, 2023-2024.

We describe introduction of the 2022-2023 Oropouche virus lineage from Brazil, which has caused large-scale outbreaks throughout Brazil, into the Amazon Region of Peru. This lineage is co-circulating with another lineage that was circulating previously. Our findings highlight the need for continued surveillance to monitor Oropouche virus in Peru.

Differential Disease Behavior of Immune-Mediated Colitis Among Different Types of Immune Checkpoint Inhibition.

Background: Immune-checkpoint inhibitors (ICIs) enhance the immune response against cancer but can cause immune-related adverse events, with immune-mediated colitis (IMC) being among the most common.

Objective: We investigated variations in gastrointestinal disease behavior and outcomes among patients receiving different ICI regimens.

Methods: This retrospective chart review included patients who received ICIs and developed IMC.

Chiroptical Signature and Absolute Configuration of Tröger's Base-Based Triangular Macrocycles.

Chiral macrocycles are an attractive subject in supramolecular chemistry because of their proven relevance in appealing applications such as asymmetric catalysis, selective absorption, or chiral recognition. Taking into account the strong topological nature of these topics, the determination of the exact 3D structure of a chiral macrocycle becomes critical to developing all of its potential usages. In this paper, we have addressed the absolute configuration determination of a Tröger's base-based triangular macrocycle, , by means of vibrational and electronic chiroptical spectroscopy with the support of DFT quantum chemistry calculations.
