New rapid and point of care Hepatitis C tests could be global game changers

15 Oct 2012

Timely screening and diagnosis is critical to the success of new treatments and ultimately to the survival of hepatitis C patients. A new study led by the Research Institute of the McGill University Health Centre (RI MUHC) is the first to show that hepatitis C rapid and point of care tests with a quick turnaround time are highly accurate and reliable as conventional first-line laboratory tests. This head-to-head analysis, published in the current issue of the Annals of Internal Medicine, will lead to changes in screening practices and ultimately impact the control of hepatitis C infection worldwide.

 

Treating ovarian cancer: new pathways through genetics

24 Sep 2012

A new discovery that sheds light on the genetic makeup of ovarian cancer cells could explain why some women survive longer than others with this deadly disease. A multi-disciplinary team led by the Research Institute of the McGill University Health Centre (RI MUHC), in collaboration with the Lady Davis Institute of the Jewish General Hospital and the University of Montreal Hospital Research Centre, has identified genetic patterns in ovarian cancer tumours that help to differentiate patients based on the length of their survival after initial surgery. The study was published in the journal PLOS ONE.

 

Vitamin B12 deficiency: tracking the genetic causes

26 Aug 2012

Vitamin B12 is essential to human health. However, some people have inherited conditions that leave them unable to process vitamin B12. As a result they are prone to serious health problems, including developmental delay, psychosis, stroke and dementia. An international research team recently discovered a new genetic disease related to vitamin B12 deficiency by identifying a gene that is vital to the transport of vitamin into the cells of the body. This discovery will help doctors better diagnose this rare genetic disorder and open the door to new treatments. The findings are published in the journal Nature Genetics.

Coordinated protein breakdown and synthesis: a key to healthy growth of cells

16 Aug 2012

The cells in our bodies are involved in a continuous process of breakdown and re-growth that is essential to life itself. During a process that can be likened to self-cannibalism, the proteins within the cells are broken down into their component amino acids, which then act as the building blocks for the growth and renewal of cells. Serious diseases may result from a disruption of this process. This is the case with cancer, where cancerous cells grow quickly, but the ability of the cells to digest themselves is compromised. 
 

Caffeine may ease Parkinson's

1 Aug 2012

Caffeine, which is widely consumed around the world in coffee, tea and soft drinks, may help control movement in people suffering from Parkinson's. This is the finding of a study conducted at the Research Institute of the McGill University Health Centre (RI MUHC) that was recently published in Neurology®, the official journal of the American Academy of Neurology. The study opens the door to new treatment options for Parkinson's disease that affects approximately 100 000 Canadians.

 

New Cause of Childhood Blindness Identified

29 Jul 2012

One of the mysteries of blindness has been solved. A team of international scientists in collaboration with the Research Institute of the McGill University Health Centre (RI MUHC) identified a new gene responsible for Leber Congenital Amaurosis (LCA), a devastating genetic form of blindness in newborns.

Study confirms uncircumcised boys are at higher risk of urinary tract infections

10 Jul 2012
A new study led by the Research Institute of the McGill University Health Centre (MUHC) shows that boys who are uncircumcised are at higher risk of urinary tract infections (UTIs), regardless of whether their foreskin is tight and non-retractable – a fact that was not previously known. These findings were recently published in CMAJ (Canadian Medical Association Journal).

Elderly women with irregular heartbeat at higher risk for strokeA

9 May 2012

Older women who have been diagnosed with an irregular heartbeat are at higher risk of stroke than men. A new study led by the Research Institute of the McGill University Health Centre (RI MUHC) shows that warfarin, the most common anticoagulant therapy used to prevent stroke in patients with Atrial fibrillation (AF) may not be as effective in women, 75 years or older, as in men. The results of the study are published in the Journal of the American Medical Association (JAMA).

How accurate are flu tests?

28 Feb 2012
A new study conducted by researchers from McGill University, the Research Institute of the McGill University Health Centre (RI MUHC), and Sainte-Justine University Hospital Research Centre, Montreal, has put the accuracy of rapid influenza diagnostic tests (RIDTs) under the microscope.
