Poor health in prisons

Canadians in jails and prisons are more likely to have mental health or substance abuse issues compared to the general population, according to a review of the available evidence. Additionally Canadians in jail or prison are more likely to attempt suicide. More than half of the individuals incarcerated in federal or provincial prisons and jails […]

Strengthening the link between Zika and microcephaly

Evidence supporting the link between the Zika virus and microcephaly has been found in a retrospective study of the outbreak in French Polynesia between October, 2013 and April, 2014. Researchers examined medical records to find cases of microcephaly between September, 2013 and July, 2015. They found eight cases of microcephaly during this time, seven of […]

Improving the cellular backpack

Medicine can be delivered to specific parts of the body by fitting it inside a “backpack” and attaching it to white blood cells. This targeted drug delivery means other tissues of the body aren’t affected, and side effects are limited.  Original research presented at a meeting of the American Chemical Society on March 17, 2015.

Screening for lung cancer – New Canadian guidelines

New lung cancer screening guidelines have been released by the Canadian Task Force on Preventive Health Care. The guidelines take into account the latest evidence and aim to balance the benefits of early detection against the harms caused by overdiagnosis and invasive testing. The new guidelines recommend annual CT scans for adults aged 55-74 years […]

Improving cataracts outcome using stem cells

A new study is showing that preserving the stem cells within the eye might be a more effective way to treat cataracts, at least in children. Researchers surgically removed the damaged lens using a new technique that allowed them to preserve the lens epithelial stem cells. The minimally invasive surgery facilitated functional lens regeneration in […]

Meat -­ The great evolutionary kickstarter

It was the addition of meat into the human diet, along with tool use, that could have contributed to our ancient ancestors’ improved speech and the ability to regulate body temperature, researchers suggest. In the past the cooking of food was thought to drive the changes in tooth size and facial features of our ancestors. […]

Protecting healthcare workers – Masks v. Respirators

  Respirators and surgical masks both help protect health workers from respiratory infections, however there has been a debate about which is more effective and different guidelines provide different recommendations. A review of the accumulated evidence does not suggest that the N95 respirator is superior to surgical masks. The authors suggest a randomized controlled trial, […]

Urgent action needed against mycotoxin contamination

The International Association for Research on Cancer is urging action against widespread mycotoxin contamination in developing countries. More than 500 million people are being exposed to fungal toxins, which can cause illness and even death. Dr. David Miller, from Carleton University, is the chair of the working group. Original research published by the International Agency for Research on […]

Printing living bones may be possible

Printing bones and cartilage could be the way of the future. Using specialized ‘bioprinters’, researchers have been able to “print” cells into layered patterns reconstructing human body parts. Current 3D printers are unable to create bone and cartilage with enough structural stability. By combining bioprinters with biodegradable polymer materials researchers were able to “create” the […]

Something’s fishy about childhood obesity

Eating fish more than three times a week during pregnancy is associated with an increased risk of childhood obesity, according to the results of a new study. Women who ate fish more than three times per week were more likely to give birth to children with higher BMI values at ages two, four, and six. […]
