What influences critical care doctors in withdrawing life support for patients with brain injury?

A study in CMAJ provides new insights into the decision-making processes of critical care physicians and families in withdrawing life-sustaining treatments from critically ill patients with severe brain injury. Key findings include the influence of patient circumstances, family wishes, severity and location of the injury, past physicia...

Preventing drugs from being transported

A research team created an artificially produced antibody fragment that successfully blocks the transport of antibiotics and chemotherapy agents out of cancer cells. By binding to a specific protein, the fragment prevented the protein from splitting ATP, thus stopping the transport process.

Receiving opioids for the first time while hospitalized doubles the risk of continued use

A retrospective cohort study found that patients who received opioids for the first time while hospitalized had double the risk of continuing to receive opioids for months after discharge. Researchers reviewed electronic health records of 191,249 hospital admissions and found that almost 6% of patients receiving opioids during their ho...

More heart failure patients may benefit from CRT defibrillator

A new study found that cardiac resynchronization therapy with defibrillator (CRT-D) may improve heart function in certain groups of heart failure patients, particularly those with nonspecific intraventricular conduction delay (NICD) and a QRS duration of more than 150 milliseconds. In these patients, CRT-D was associated with decreased...

Dundee lab solves HOIL-1 mystery

Researchers at the University of Dundee have made a significant breakthrough in understanding the function of HOIL-1, a key protein involved in cell survival. The study reveals that HOIL-1 operates in tandem with another component to form ubiquitin chains, and joins proteins using an unusual ester bond mechanism.

Study reveals new genomic roots of ecological adaptation in polar bear evolution

A recent study by UMass Amherst researchers found that polar bears possess fewer copies of genes related to olfactory receptors and salivary amylase, adaptations that enable them to thrive on a fully carnivorous diet. This discovery sheds light on the genomic foundation of ecological adaptation in polar bear evolution.

Past climate change: A warning for the future?

A new study of past climate changes and their effects on ancient societies offers lessons for the future. Climate disruptions in prehistoric Amazonia, such as changes in rainfall patterns and agriculture, may be comparable to the current human-caused climate change affecting most parts of the world.

Wheat myth debunked

A new study debunks the myth that intensive breeding has made modern wheat cultivars weaker. Modern wheat varieties actually out-perform older ones in both optimal and sub-optimum growing conditions. This finding could have significant implications for raising productivity in organic cropping systems.

The brain consumes half of a child's energy -- and that could matter for weight gain

A new paper suggests that variation in brain energy expenditure during childhood may influence patterns of energy expenditure and weight gain. The study proposes a hypothesis linking the brain's energy demand to obesity risk, highlighting the need for further research into the role of brain development on body weight.

Shedding light on 'black box' of inpatient opioid use

A recent study published in Annals of Internal Medicine has shed light on the practices surrounding inpatient opioid prescribing, revealing that patients who receive opioids during hospitalization are more likely to continue using them after discharge. The research, conducted by scientists at the University of Pittsburgh Graduate Schoo...
