Experimental type of vaccine could prevent hospital-acquired infections

Hospitals are meant to be places of healing, but patients often pick up new infections there that are potentially dangerous and hard to treat. A new, experimental vaccine given on arrival to hospital could help prevent infections from a range of drug-resistant bacteria and fungi, by activating a different arm of the immune system. With […]

Acute Middle Ear Infections in Children: Evidence on Ways to Prevent and Treat Them

By SARAH CHAPMAN Take-home points Acute middle ear infections, also called acute otitis media, are common in children and can cause earache, fever and occasionally a perforated ear drum (a hole or tear in your eardrum). These infections happen when bacteria from the upper part of the throat go to the middle ear. NHS advice is that […]

Move over long COVID, ‘long colds’ are a thing, too

A new study has found that people with non-COVID respiratory infections such as colds, flu, and pneumonia can suffer from ‘long’ symptoms that persist well beyond the acute infection stage. The findings increase awareness about the existence of long-lasting respiratory infections other than long COVID. We’ve all heard of long COVID, where the signs and […]

But the U.S. Centers for Disease Control and Prevention’s messaging […]

A retrospective study of Aeromonas hydrophila infections at a university tertiary hospital in Saudi Arabia

Aeromonas hydrophila risk factors, clinical disease, and factors associated with mortality were studied in a large hospital in Saudi Arabia. This is the first study from this region about this particular species. The Pitt bacteremia score, Charlson weighted comorbidity index, INR, and the number of comorbidity factors were all found to be associated with 30-day […]

Antiviral responses are shaped by heterogeneity in viral replication dynamics

Abstract Antiviral signalling, which can be activated in host cells upon virus infection, restricts virus replication and communicates infection status to neighbouring cells. The antiviral response is heterogeneous, both quantitatively (efficiency of response activation) and qualitatively (transcribed antiviral gene set). To investigate the basis of this heterogeneity, we combined Virus Infection Real-time IMaging (VIRIM), a […]
