Ogilvie's Syndrome Following Herpes Zoster Infection: A Comprehensive Review of the Literature.

This systematic review explores the association between herpes zoster (HZ) infection and Ogilvie's syndrome (acute colonic pseudo-obstruction), evaluating how varicella-zoster virus (VZV) reactivation may contribute to autonomic dysfunction leading to intestinal obstruction. A comprehensive search was conducted in PubMed, Scopus, and Cochrane Library databases up to October 2024, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies included case reports, clinical images, and letters reporting Ogilvie's syndrome secondary to HZ or VZV infection.

Defect characterization in optical coatings using scattered light.

Optical coatings play a vital role in sensing technologies. The development of new coatings that exhibit minimal optical losses requires a detailed understanding of the development of defects within them. Current methods of defect characterization involve direct microscope imaging or x-ray diffraction studies in the case of crystallites.

Photon emission spectrum of ion pumps.

As the sensitivity of gravitational-wave detectors increases, new sources of noise appear. A potential source of noise may arise from charge accumulating on the mirrors of the experiment, the origin of which can be related to UV photons from the surroundings. In order to test one hypothesis, we measured the photon emission spectrum from a type of ion pump that is used in the experiment, an Agilent VacIon Plus 2500 l/s.
