Immune System Of Newborn Babies Stronger Than Previously Thought

The team discovered that whilst T cells in newborn babies are largely different to those in adults, it is not because they are immunosuppressed; rather, they manufacture a potent anti-bacterial molecule known as IL8 that has not previously been considered a major product of T cells, and that activates neutrophils to attack the body's foreign invaders.

Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study led by King’s College London. Although their immune system works very differently to that of adults, babies may still be able to mount a strong immune defense, finds the [...]

Cooling Of Dialysis Fluids Protects Against Brain Damage

Dialysis device (stock image). While dialysis is an essential treatment for many patients with kidney disease, it can cause damage to multiple organs, including the brain and heart, due to the sudden removal of bodily fluids. Cooling dialysis fluids can protect against brain damage, new research shows.

While dialysis can cause blood pressure changes that damage the brain, cooling dialysis fluids can protect against such effects. The findings come from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The cooling intervention can be delivered without additional cost and is simple to perform. While [...]

How Pneumonia Bacteria Can Compromise Heart Health

Bacterial pneumonia in adults carries an elevated risk for adverse cardiac events (such as heart failure, arrhythmias, and heart attacks) that contribute substantially to mortality — but how the heart is compromised has been unclear. A study published on in PLOS Pathogens now demonstrates that Streptococcus pneumoniae, the bacterium responsible for most cases of bacterial [...]

Making Light Of A Serious Situation


The last item on a hospitalized patient’s agenda is to contract more illnesses during their stay. Unfortunately, The CDC estimates that 5% t of all hospital admissions result in infections that patients acquire during their stay while receiving treatment for other conditions. This culminates in 1.7 million infections and 99,000 deaths each year, as well [...]

Dangerous new pathogens such as the Ebola virus invoke scary scenarios of deadly epidemics, but even ancient scourges such as the bubonic plague are still providing researchers with new insights on how the body responds to infections. In a study published online in the journal Immunity, researchers at Duke Medicine and Duke-NUS Graduate Medical School [...]
