C3aR1-Deletion Delays Retinal Degeneration in a White-Light Damage Mouse Model.

Purpose: In the aging retina, persistent activation of microglia is known to play a key role in retinal degenerative diseases like age-related macular degeneration (AMD). Furthermore, dysregulation of the alternative complement pathway is generally accepted as the main driver for AMD disease progression and microglia are important producers of local complement and are equipped with complement receptors themselves. Here, we investigate the involvement of anaphylatoxin signaling, predominantly on Iba1+ cell activity, in light-induced retinal degeneration as a model for dry AMD, using anaphylatoxin receptor knockout (KO) mice.

A Possible Phenotype-to-Genotype Association of Novel Single-Nucleotide Variants in the Coding Exons of the Gene to Arterial Aneurysmal and Dissection Diseases.

After reporting the first known clinical case associating compound heterozygous single-nucleotide variants in Exon 2 of to aortic aneurysmal and iliac dissection, we began prospective surveillance in our vascular genetic practice for similar cases. Herein, we present nine (9) subjects from a total cohort of 135 with arterial aneurysms or dissections who revealed single-nucleotide variants in with no other alterations in a panel of 35 genes associated with aneurysmal and dissection disorders. Five out of nine (5/9) single-nucleotide variants were in Exon 1, and four out of nine (4/9) mutations were in Exon 2, both of which are principal coding exons for this gene.

[Development of paranasal sinus surgery in Austria and Switzerland: past, present, and future].

Thanks to our predecessors and technical progress, we can nowadays offer our patients a safe and modern paranasal sinus surgery. This article provides an overview of the historical development of paranasal sinus surgery in Austria and Switzerland and to shed light on the dynamic progress of this discipline in an international context. Paranasal sinus surgery has undergone significant change in recent decades, driven by rapid technological advances that have significantly improved surgical procedures and operative outcomes.

Delivering the News of an Intraoperative Death; Literature Based Guidance from the AATS Wellness Committee.

Objectives: Fortunately, operating room deaths and unexpected deaths are infrequent occurrences. However, when they occur, the surgeon is called upon to deliver this news to family and loved ones. There is a paucity of literature on this topic and little guidance preparing cardiothoracic surgeons for this important but difficult situation.

The epidemiology and clinical presentation of seropositive neuromyelitis optica spectrum disorder in a US population.

Objective: To define the epidemiology and clinical presentation of seropositive neuromyelitis optica spectrum disorder (NMOSD) in a large US health system.

Methods: We completed a retrospective observational study of adult patients in the University of Colorado Health System from 1 January 2011 to 31 December 2020, using Health Data Compass (HDC), a data warehouse that combines electronic health information with claims and public health data in Colorado. We screened HDC for patients with either (1) an abnormal aquaporin-4 IgG test or (2) any G36 ICD-10 code.
