Research reveals how gut macrophages respond to prior infection by shielding enteric neurons - News-Medical.net

Image
A simple stomach bug could do a lot of damage. There are 100 million neurons scattered along the gastrointestinal tract-;directly in the line of fire-;that can be stamped out by gut infections, potentially leading to long-term GI disease. But there may be an upside to enteric infection. A new study finds that mice infected with bacteria or parasites develop a unique form of tolerance quite unlike the textbook immune response. The research, published in Cell , describes how gut macrophages respond to prior insult by shielding enteric neurons, preventing them from dying off when future pathogens strike. These findings may ultimately have clinical implications for conditions such as irritable bowel syndrome, which have been linked to the runaway death of intestinal neurons. We're describing a sort of innate memory that persists after the primary infection is gone. This tolerance does not exist to kill future pathogens, but to deal with the damage that infection causes-;prese...

When the first stories about a mysterious respiratory virus began to seep out of China in January 2020, University of Manitoba researcher Keith Fowke was in Kenya for a scientific conference at the University of Nairobi's Institute for Tropical Infectious Diseases. The topic? HIV and other emerging viruses. But even Fowke, who's spent decades unravelling the mysteries of these conditions—most notably, uncovering a natural immunity to HIV that has transformed how we treat it—was taken aback by the pace and persistence of this new threat. "The news was concerning, but at first it seemed like a regional issue," says Fowke [BSc(Hons)/88, PhD/95] , who is head of UM's department of medical microbiology and infectious diseases. "We didn't correctly anticipate the speed of transmission of the virus or the impact of the disease. It shut down the world economy. COVID-19 caught us by surprise." Yet, it's possibility was never in doubt. At least not in ...

Rapid incidence estimation from SARS-CoV-2 genomes reveals decreased case detection in Europe during summer 2020 - Nature.com

Image
Abstract By October 2021, 230 million SARS-CoV-2 diagnoses have been reported. Yet, a considerable proportion of cases remains undetected. Here, we propose GInPipe, a method that rapidly reconstructs SARS-CoV-2 incidence profiles solely from publicly available, time-stamped viral genomes. We validate GInPipe against simulated outbreaks and elaborate phylodynamic analyses. Using available sequence data, we reconstruct incidence histories for Denmark, Scotland, Switzerland, and Victoria (Australia) and demonstrate, how to use the method to investigate the effects of changing testing policies on case ascertainment. Specifically, we find that under-reporting was highest during summer 2020 in Europe, coinciding with more liberal testing policies at times of low testing capacities. Due to the increased use of real-time sequencing, it is envisaged that GInPipe can complement established surveillance tools to monitor the SARS-CoV-2 pandemic. In post-pandemic times, when diagnostic efforts are ...

Why Horizon, NJ's largest health insurer, got Murphy's approval to restructure - Asbury Park Press

Costello, Asbury Park Press Horizon Blue Cross Blue Shield of New Jersey, the state's largest health insurer, can restructure in ways the company says will give it flexibility in a rapidly evolving marketplace, but which consumer advocates fear opens the door to its becoming a for-profit giant beholden to shareholders. Gov. Phil Murphy announced Wednesday afternoon that he had signed legislation allowing the insurer to transition from a not-for-profit organization to a not-for-profit mutual holding company — a distinction that Horizon has said would free it of strict state rules that put it at a competitive disadvantage.  The change would...

Infectious Colitis: Types and Treatments - Verywell Health

Image
Colitis refers to inflammation in your large intestine, or colon. It covers different types of inflammation that affect this organ, and can include Crohn's disease, which affects the lining of the small and large intestines, and ulcerative colitis, which causes irritation and ulcers in the colon. Both of these conditions are forms of inflammatory bowel disease (IBD), which is a group of disorders that cause chronic inflammation in the intestines. Phynart Studio / Getty Images Types Infectious colitis can be caused by bacteria, viruses, or parasites. Bacterial A large number of cases of infectious colitis are caused by bacteria, specifically food-borne bacteria. Common causes of bacterial colitis include: Viral Infectious colitis can also be caused by viruses like the cytomegalovirus (CMV). It is a common virus that can be spread through bodily fluids like saliva, blood, urine, semen, and vaginal fluids. It ca...
