Dr. Cara Tannenbaum (Canadian Institutes of Health Research) and Dr. Janine Austin Clayton, (National Institutes of Health, USA), have written a Viewpoint article published in JAMA highlighting the problem.
More children are exposed to household tobacco smoke in early childhood, the greater their risk of adopting antisocial behavior toward others, engaging in proactive and reactive aggression, having conduct problems at school, and dropping out at age 12.

A new study, whose preliminary results will be presented today at the Canadian Cardiovascular Congress and soon be published in the Journal of Cardiopulmonary Rehabilitation and Prevention, shows that even low physical fitness, up to 20% below the average for healthy people, is sufficient to produce a preventive effect on most of the risk factors that affect people with cardiovascular disease.
A study conducted by Canadian and Australian researchers shows that nearly everywhere in Canada, the provinces and territories impose obstacles to reimbursement of new direct-acting antivirals (DAA) to treat hepatitis C by because of their cost.

Recent studies on a small number of patients with leukemia treated with bone marrow transplantation have suggested that the presence of the common cytomegalovirus (CMV) in patients or their donors may protect against relapse or even death after the transplant. A large international study published in the journal Blood now shows the opposite. The virus not only does not prevent leukemia relapse, but also remains a major factor associated with the risk of death.

A study published in the Journal of Neuropsychology, reveals the adverse effects of mild traumatic brain injury (mTBI) on the quality parent-child relationships. The young brain is particularly vulnerable to injury and one of the first visible signs of social difficulties in young children is a decline in their relationship with their parents.
A recent study has demonstrated that, beyond causing memory problems, Alzheimer’s disease also impairs visual face perception. This finding may help families better understand their loved one's inevitable difficulties and lead to new avenues to postpone this painful aspect of the disease, such as the recognition of particular facial traits or voice recognition.
Findings recently published in The Journal of Sex Research contradict the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), as they demonstrate that a number of legal sexual interests and behaviors considered anomalous in psychiatry are actually common in the general population. Researchers have reasons to believe that this study’s results which are based on Quebec’s population can be applied to the population of North America and Europe as well.
