A randomized study on 1047 university students showed that online interventions can be effective at helping them cope with mental health disorders.University is a time when many students are at risk from common mental health disorders such as depression, anxiety, eating disorders and alcohol and drug abuse. The study showed that students at high […]

Measuring the brain’s anti-distraction system
Researchers have used EEGs (electoencephalogram) to show that a newly discovered type of neural process that works to overcome a distraction. When your gaze shifts to follow a distraction, neural circuits in your brain gives off signals that can be detected during an EEG. The discovery could help develop new strategies to avoid distracted driving or offer […]
Tamiflu & Relenza: how effective are they?
Governments across the world stock-pile flu vaccines and antiviral drugs like Tamiflu (oeltamivir) and Relenza (zanamivir). While vaccines can prevent flu virus, the antiviral drugs are only designed to fight an infection that’s already underway. A new review of 46 clinical trials studies by The Cochrane Collaboration and the British Medical Journal shows that while both antiviral […]
Gene mutations linked to childhood brain tumours
Two Canadian studies have found gene mutations that are linked to deadly brain tumors and could help scientists understand the causes of childhood brain cancer. In the first paper, researchers found mutations in a gene called ACVR1 in 20 per cent of a highly aggressive and difficult to treat childhood brain tumour, called diffuse intrinsic […]
Tracing the ‘brain noise’ of schizophrenia
Using a simple eye-tracking experiment, researchers have shown that patients with schizophrenia make more errors when trying to locate visual signals than control patients. The pattern of errors can be used to make computer models of the noise in what are called ‘corollary discharge signals.’ These signals are how one part of the brain keeps […]
Molecule can help detect and prevent diabetes
Nearly a fifth of pregnant women develop a temporary form of diabetes – called gestational diabetes – that puts them at greater risk for developing type 2 diabetes later in life. A new study shows how a molecule called CMPF can help detect diabetes. An analysis of blood chemistry in a sub-population of subjects has […]
Men with depression spend more time on their computers
A new study tracked screen time – time spent watching TV or using a computer – among 761 Montreal-area subjects in their mid-twenties. While all the subjects spent more time in front of screens than is generally considered healthy, men who had previously self-identified symptoms of depression spent more time using computers than women with […]
Hockey a major cause of youth concussions
A recently published study tracked 2,112 concussion patients under the age of 18 arriving at a London, ON health centre between 2006 and 2011. It found that nearly half of all concussions were caused by sports, and that more than a third of these were from hockey alone. Two thirds of the concussions occurred in […]
Saliva gene linked to obesity
Having a high copy number of a gene increases the expression of the protein it encodes. A new genomic study on 6,200 subjects found a link between a low copy number of the gene for amylase — a salivary protein which breaks starch down into digestible sugar — with obesity and high body mass index […]
The ethical implications of newborn genome screening
Newborn screening relies on whole-genome sequencing to look for genetic, endrocine or metabolic disorders in babies. In a commentary article, the authors provides a list of questions about ethical, legal, and social issues raised by the future of newborn screening. They argue that the child interests should be taken into account when any changes in […]
How ‘drug holidays’ may improve cancer treatment
Studies on melanomas in mice have shown that tumors which developed resistance to the anti-cancer drug vemurafenib could regain sensitivity to the treatment after a ‘drug holiday’. A new study shows that melanoma human patients that have developed resistance can regain sensitivity to the drug after a drug holiday of seven days. This means that […]
Availability of sugar-sweetened beverages in schools increases odds of teenage obesity
Previous research has shown that students drink more sugar-sweetened beverages (SSBs) when they attend a school where they are available. A new study that surveyed 11,385 students from 174 secondary schools in British Columbia – 43% of which reported access to SSBs. The researchers found that students who attend schools where SSBs were available have […]
Nurses are effective at treating a common arm injury in young children
‘Pulled elbow’, or radial-head subluxation, is a common arm injury in children. It’s easy to diagnose and quick to fix but children usually wait hours in the emergency department. Researchers performed an open, cluster-randomized controlled trial of 268 cases to determine whether triage nurses in the emergency department could fix the condition, thereby freeing up […]
Immunization? There’s an app for that
A smartphone app called ImmunizeCA helps patients and their families keep track of which immunizations they have and haven’t received. The app has been developed through a collaboration between the Canadian Public Health Association (CPHA), Immunize Canada, and the Ottawa Hospital Research Institute (OHRI) with funding from the Public Health Agency of Canada.
Growing leukemia stem cells in the lab
Previous attempts to grow leukemia stem cells outside the body have fallen short, as the cells lose their cancer stem cell characteristics. Now, scientists have found a way to grow and maintain ‘healthy’ leukemia cancer stem cells outside of the body. This opens the way to screens for drugs that can block the cells’ ability […]
Promoting a healthy diet at the check-out line
Researchers have found a relationship between the median income and soft drink purchases in Montreal. Researchers used records from scanning equipment at grocery store checkout lines to track soft drink purchases in various Montreal neighbourhoods. They found that for every $10,000 decline in the local median income there was a five-fold increase in soft drink […]
