Blood test reveals prognosis after cardiac arrest

Lund University
Peer-Reviewed Publication

A blood biomarker yet to be used in cardiac arrest care can give a clearer picture of the extent of brain damage after a cardiac arrest. This has been shown in a large international multicentre study led by researchers at Lund University that has been published in The Lancet Respiratory Medicine. Worldwide, around four million people each year suffer a sudden cardiac arrest

“This will transform care for these patients,” says researcher Marion Moseby Knappe.

Peer-Reviewed Publication

A single-dose oral medication called zoliflodacin shows promise as a new treatment for antibiotic-resistant gonorrhoea, according to a phase 3 clinical trial published in The Lancet. The study found that one dose of zoliflodacin was as effective as the current standard treatment, which combines two antibiotics: an injection of ceftriaxone followed by an oral dose of azithromycin.

Peer-Reviewed Publication

The old proverb “it takes a village to raise a child” also applies to preventing youth suicide, according to UBC Okanagan researchers who found that community support is essential.

In Canada, suicide is the fourth leading cause of death among children under 14 and the second for youth and young adults between 15 and 34 years old. The UBCO Faculty of Health and Social Development researchers say governments, schools and community agencies need to rethink how youth suicide prevention efforts are designed.

Long term biochar aging reshapes antibiotic transport in farmland soils, new study finds

Biochar Editorial Office, Shenyang Agricultural University

A new study published in Biochar reveals that biochar, a carbon rich soil amendment widely used to improve soil health and reduce pollution, continues to influence the movement of veterinary antibiotics in farmland soils even after five years in the field. The work shows that biochar’s ability to retain pollutants changes in surprising ways over time, shifting from adsorption driven effects in the first year to soil structure driven mechanisms after long term aging.
