Researchers focused on those with rheumatoid arthritis, lupus, inflammatory bowel disease, multiple sclerosis and other immune-mediated inflammatory diseases New research findings provide solid evidence that annual COVID-19 vaccine booster doses continue to be advisable for certain immunocompromised people, researchers at McGill University say.

In a study that used large language models to analyze healthcare records of Quebec francophone children, scientists argue that current criteria for diagnosing autism are in need of revision.

Researchers suggest behavioural traits are more telling than social communication and interaction factors, so diagnostic focus should be sharpened An analysis of digital health records using large language models (LLMs) is challenging a long-held belief about the clinical identifiers of autism. A new study led by researchers at The Neuro (Montreal Neurological Institute-Hospital) of McGill University and Mila Quebec AI Institute found that social communication factors may not be as important in identifying the condition as previously believed.

A large-scale study in which UdeM cardiologist Rafik Tadros took part focuses on the origins of hypertrophic cardiomyopathy, or HCM. Affecting one in 500 people, hypertrophic cardiomyopathy is a condition in which the walls of the left ventricle, the heart's main pumping chamber, become abnormally thick.

A new study led by Western researchers is the first to identify a factor that could influence how fast the pocket where human immunodeficiency virus (HIV) hides dormant inside of cells shrinks when treated. HIV is difficult to cure, partly due to the virus' ability to create a "latent reservoir" - where it hides dormant inside of cells, safe from detection.

In Quebec, most first-time food bank users don't have to keep going back, but 40 per cent still rely on the service two years later, an UdeM study shows.

For people with a certain sleep disorder, a simple blood test could help predict the development of dementia years before symptoms appear, a new study indicates. Idiopathic REM sleep behaviour disorder (iRBD) causes people to physically act out their dreams while sleeping. The disorder is also associated with a very high risk of Parkinson's disease and a related condition called Dementia with Lewy Bodies.

A new way to measure male fertility has been discovered by researchers at the University of Waterloo, opening the door to the development of simple, inexpensive tests for clinical and at-home use. The research team combined expertise in sperm cell behaviour and interface science to determine that the movement of healthy sperm within semen reduces the force with which droplets stick to a water-repellent surface.

The prevalence of the four main types of this virus is less than 1% in young Quebecers aged 16 to 20 who have not received the vaccine. Less than 20 years after its introduction in Quebec, the human papillomavirus (HPV) vaccination program is so effective that even unvaccinated young people are benefiting from a form of immunity.

One-third of older Canadians at nutritional risk, study finds. One-third of Canadian adults aged 55 or older are nutritionally at risk, potentially leading to increased hospital stays, more emergency visits and physician consultations for possible infections, a new study found. The University of Waterloo researchers assessed data from more than 22,000 community-dwelling adults aged 55 and over from the Canadian Longitudinal Study on Aging.

Researchers at the UdeM-affiliated Saint-Justine Hospital and the ETS come up with a better way to compare magnetic resonance images taken at different institutions. From left to right: Dr Gregory A. Lodygensky, Jose Dolz, Farzad Beizaee and Christian Desrosiers Credit: CHU Sainte-Justine Magnetic resonance imaging (MRI) is an essential tool for medical clinicians, providing detailed views of the interior of the human body as well as valuable information on pathologies.

A new mathematical model developed at the University of Waterloo can determine a baby's overall drug exposure when their mother is taking medication. This is the first study to include drug transfer from the umbilical cord and through breastfeeding in determining the baby's total drug levels. The research team from the School of Pharmacy at Waterloo looked specifically at Levetiracetam.

A groundbreaking study sheds new light on the role of the gut microbiome and metabolome in CTLA4 deficiency, a key factor in immune regulation and cancer mechanisms.

For Feb.17, due to the storm, McGill teaching and work must be done remotely. Classes that cannot be done remotely will be cancelled. Labs and evaluations will be rescheduled, as appropriate. Only the McLennan Library is open for study ( see hours ). All other libraries are closed for the day. Pour le 17 février, en raison de la tempête, l'enseignement et le travail à McGill doivent être effectués à distance.

Survivors of pediatric cancer should be stress-tested for acquired long QT syndrome, a type of heart arrhythmia, researchers at UdeM and CHU Sainte-Justine say in a new study. In children, can being treated for cancer have consequences for the heart - namely, cardiac arrythmias? A new study by researchers at Université de Montréal and its affiliated CHU Sainte-Justine Azrieli Research Centre provides some answers.

In a new study, Western researchers have shown just one 20-minute session of moderate intensity aerobic exercise can improve an athlete's executive function and concussion symptoms in the early stages of recovery. Executive function is essential for everyday tasks, from remembering a grocery list to making strategic decisions in sports.

University of Calgary's Hotchkiss Brain Institute researchers with the Calgary Stroke Program at Foothills Medical Centre revolutionized treatment for stroke with the ESCAPE Trial , proving that a clot retrieval procedure known as endovascular thrombectomy (EVT) can dramatically improve patient outcomes after an acute ischemic stroke caused by a blockage in a large-sized blood vessel.

Discovery could lead to new treatment strategies for infertility, but raises potential concerns about emerging therapies for muscular dystrophy and obesity A newly discovered line of communication between body muscle and the pituitary gland may play an unexpected role in female fertility, according to a new study.

We each have a natural rhythm, and music that matches it offers the best pain relief, McGill research suggests Music has the best chance of providing pain relief when it is played at our natural rhythm, a McGill University research team has discovered. This suggests it may be possible to reduce a patient's level of pain by using technology to take a piece of music someone likes and adjust the tempo to match their internal rhythm, the researchers said.

An UdeM-led study finds that cisgender teenage girls are less likely to achieve orgasm than teenage boys. Among cisgender Quebec teenagers - that is, those whose gender identity matches their sex assigned at birth - girls are significantly less likely than boys to achieve orgasm, either through masturbation or with a partner.
