A portable device has been created to mimic the placenta's oxygenation role for pre-term newborns in respiratory distress. The artificial lung uses a fine membrane to release carbon dioxide and uptake oxygen while protecting blood from infection, improving survival rates and reducing brain damage.
A recent study by McMaster University found that only 28% of new Canadian drugs have clear pediatric data, and many critical diseases lack approved treatments. This absence perpetuates 'off-label' drug use, which can lead to inadequate treatment or increased side effects.
American mastodons moved north from southern ranges in response to warming climate conditions and melting ice sheets. Genetic analysis suggests that these massive increases in territory made northern populations more vulnerable to extinction.
Researchers at McMaster University have identified a small molecule compound that can activate the Wnt pathway in non-Wnt subtypes of medulloblastoma, making these aggressive forms of cancer more responsive to therapies. The study found that activating the Wnt pathway can function as a tumour suppressor in certain contexts.
Two new evidence reviews from McMaster University suggest that alternative treatments are as effective as opioids in managing acute musculoskeletal injuries like strains and sprains. The studies found that opioids have a higher risk of harms to patients, particularly those with past or current substance use disorders.
A team of researchers at McMaster University has discovered that the ACE2 receptor is present in very low levels in human lung tissue, suggesting alternative infection pathways. This finding challenges existing knowledge about SARS-CoV-2 entry into cells and may lead to better diagnostic devices and treatment strategies.

The study also found that HIIT is generally tolerable and poses few risks for this population.
A study by McMaster University researchers found that higher heat and humidity levels can slow the spread of COVID-19, but longer hours of sunlight are associated with a higher incidence of the disease. This suggests that sunny days may tempt people out more, increasing infection risk.
A systematic review and meta-analysis commissioned by the World Health Organization found that physical distancing reduces COVID-19 transmission. Face masks and eye protection also decrease infection risk, with limitations noted for individual protection.
Researchers developed a promising immunotherapy treatment for glioblastoma using CD133-targetting CAR-T therapy, which showed enhanced activity in preclinical models of human glioblastoma. The therapy was considered successful due to reduced tumor burden and improved survival rates.
