From ill-fitting instruments to assumptions about competence, surgical culture sidelines women, first Canadian study of its kind suggests Women now make up over half of medical students in Canada, but only one-third of practising surgeons.

After nearly 15 years' research, scientists at the UdeM-affiliated CHU Sainte-Justine have developed a compound that has shown remarkable potential in preventing prematurity in mice. Every year, 15 million babies are born prematurely around the world. For these children, each additional day in the womb can have a decisive impact on their health and quality of life.

A person diagnosed with dementia has improved survival outcomes in recent years amid significant progress in dementia diagnosis and care, according to a recent multinational study led by a University of Waterloo researcher. The study analyzed data from more than 1.2 million people over the age of 60 living with dementia in eight global regions between 2000 and 2018.

Study adds to growing evidence that social and psychological factors uniquely affect women's heart health, offering new insights into why heart disease presents and progresses differently in women Women who see themselves as having lower social status are more likely than other people to show early signs of heart stress linked to future disease risk, according to a new study led by researchers at McGill and Concordia universities.

Simon Fraser researchers are using a new approach to brain imaging that could improve how drugs are prescribed to treat Parkinson's disease. The new study , published in the journal Movement Disorders, looks at why levodopa - the main drug used in dopamine replacement therapy - is sometimes less effective in patients.

A first-of-its-kind clinical trial found that ketamine's benefits for treating severe depression can be improved when combined with psychotherapy and supportive treatment environments. Led by researchers at McGill University, the study suggests this approach can yield valuable therapeutic experiences that lead to longer-lasting relief than standard treatment.

52 babies placed in therapeutic hypothermia were monitored by electroencephalogram combined with an optical neuromonitoring system to accurately determine the severity of their brain damage.

McGill-led study shows that being 'on the same page' reduces uncertainty in tumultuous times and increases satisfaction with life and work Fostering shared understanding between romantic partners may be a powerful way for people to navigate uncertainty and build a more meaningful life, a study by McGill researchers suggests.

A groundbreaking clinical trial led by London Health Sciences Centre Research Institute (LHSCRI) and Western's Schulich School of Medicine & Dentistry may enhance how medical professionals detect hidden blood clots responsible for strokes. The study, published in The Lancet Neurology , is the first to show that extending imaging to include the heart within minutes of a patient's arrival to hospital with an acute stroke significantly improves the ability to determine the stroke's underlying cause.

Researchers at the IRCM discover that blocking the CD200R1 molecule in mice activates certain immune cells called macrophages, helping to eliminate blood cancers from their bodies. Immunotherapy has revolutionized cancer treatment by mobilizing the immune system to attack tumour cells. Major advances, such as immune checkpoint inhibitors (notably against the PD-1 protein), have produced impressive results against certain types of cancer, including melanoma and kidney cancer.

UCalgary research team discovers novel method for transforming limestone into a bacteria-killing nanoparticle Researchers at the University of Calgary have teamed up with an Alberta-based company to turn limestone into a long-lasting antimicrobial agent, a discovery that could help to cut the spread of harmful bacteria and fungi in food and health-care settings.

UdeM's veterinarians reveal that anxiety plays a key role in feline idiopathic cystitis, an inflammation of the bladder, highlighting the importance of reducing the stress that cats sometimes feel. Are recurring bouts of cystitis in cats linked to stress? Yes, indeed, according to a study of 33 cats by a behavioural medicine team at the CHUV, the animal hospital of Université de Montréal's Faculty of Veterinary Medicine.

This article takes stock of a vast international project, under the scientific direction of Walter Wittich, to define the biopsychosocial criteria for deafblindness What is deafblindness? More than the addition of two handicaps, deafblindness creates very specific challenges, since the loss of one sense is difficult to compensate for by another.

An interdisciplinary study draws on interviews with Dominicans displaced by Hurricane Maria and Tropical Storm Erika to explore the risks associated with climate change in the Caribbean.

A team of University of Calgary researchers is calling it a game-changer for understanding gut health. It has been working on improving 3D models of the human intestine to create more-realistic experiments and tests to help diagnose and treat gastrointestinal issues. Using patient-derived organoids, which are akin to mini-guts, enabled the team to more accurately replicate the internal environment of an intestine on a new gut-on-a-chip platform.

Consensus on how mindset and surroundings shape therapy outcomes is an important step toward regulatory approval for use of drugs like MDMA and psilocybin in treatment of debilitating mental health conditions As psychedelics gain traction as potential treatments for mental health disorders, an international study led by researchers at McGill University, Imperial College London, and the University of Exeter stands to improve the rigour and reliability of clinical research.

A research project charts the intersection of exposure and vulnerability to gambling to identify high-risk areas and help authorities make informed decisions. The lure of gambling is everywhere: slot machines, casinos, bingo halls, horse racing and lotteries are all'around us. People who are vulnerable to their call are exposed to their physical presence every day.

Vaccination can help prevent infection-related hearing loss in children, but its full potential remains untapped, especially in lowand middle-income countries, a study finds. Over 1.5 billion people worldwide are affected by some degree of hearing loss. While it is often linked to aging, a lesser-known but significant cause is infections contracted during childhood and adolescence, many of which are preventable.

Can clinicians predict how Parkinson's disease or Lewy body dementia will progress in the brain? UdeM medical professor Shady Rahayel looks into the question. At the Centre for Advanced Research in Sleep Medicine (CARSM), at Montreal's Sacré-Coeur Hospital, Université de Montréal medical professor Shady Rahayel sees many patients with REM Sleep Behaviour Disorder (RBD).
