Breastfeeding, child nutrition and exposure secondhand tobacco smoke at an early age may play a role in the onset of inflammatory bowel disease, according to a study conducted on Quebecers. A research team led by Professor Marie-Claude Rousseau of the Institut national de la recherche scientifique (INRS) and Dr. Prévost Jantchou, reseracher at the Centre de recherche Azrieli du CHU Sainte-Justine and professor in the Department of Pediatrics at Université de Montréal has made several promising discoveries regarding risk factors for inflammatory bowel diseases (IBDs).

A genetic signature in newborns can predict neonatal sepsis before symptoms even start to show, according to a new study. The study, led by UBC and SFU researchers in collaboration with the Medical Research Council (MRC) Unit The Gambia, has the potential to help healthcare workers diagnose babies earlier, including in lowerand middle-income countries (LMICs) where neonatal sepsis is of particular concern.

Western researchers are taking a unique global approach to finding an effective treatment for people living with long COVID. Led by Schulich School of Medicine & Dentistry professor Douglas Fraser, the projects represent the first multi-continental research conducted on long COVID, with study sites in Africa and North and South Americas.

Researchers from the University of Waterloo have developed a new technology that can hold an entire course of antibiotics in one tiny dose and deliver on demand just the right amount of medication that a particular patient needs to fight an infection. This breakthrough in targeted medicine is the result of two new studies that tested this drug-delivery system on two bacterial strains that negatively affect millions of people worldwide.

A collaborative study sheds light on how cannabis use affects brain development in young people, the main one being atrophy of certain regions of the cerebral cortex. Cannabis use may lead to thinning of the cerebral cortex in adolescents according to a recent study led by Graciela Pineyro and Tomas Paus , according to a recent study led by Graciela Pineyro and Tomas Paus, researchers at CHU Sainte-Justine and professors at the Université de Montréal Faculty of Medicine.

People with opioid use disorder in British Columbia who received methadone had a 37-40 per cent lower rate of treatment discontinuation compared with those who received buprenorphine/naloxone. The new research, published this week in the Journal of the American Medical Association , evaluated the risk of treatment discontinuation and mortality in people prescribed opioid agonist treatment (OAT) over a 10-year period.

According to the Heart & Stroke Foundation , each year around 60,000 Canadians experience their first heart attack. Heart attacks happen when blockages in the coronary arteries prevent oxygen and nutrients from reaching the heart, leading to cell death and scarring. This damage can eventually result in heart failure.

McGill discovery explains link, highlights the importance of adequate vitamin D intake, especially in children. As Canadians brace for "vitamin D winter" - months when the sun's angle is too low to produce the vitamin in the skin - a McGill University study explains why vitamin D deficiency early in life is associated with a higher risk of autoimmune diseases.

A new study reveals children with autism have a keen interest in letters and numbers - something their parents don't always spot. During diagnostic assessments, many autistic children spontaneously head to the magnetic board with letters and numbers. How common is this interest in letters and numbers among autistic children?

New research gives another reason to take folic acid supplements while pregnant. A new study by Simon Fraser researchers has found that folate may weaken the link between blood-lead levels in pregnant women and autistic-like behaviours in their children. Researchers from SFU's Faculty of Health Sciences, led by PhD candidate Joshua Alampi, published the study in the journal Environmental Health Perspectives.

What can Twitter tell us about how people complied - or not - with public-health measures during the COVID-19 pandemic? Quebec researchers Hélène Carabin and José Denis-Robichaud investigate. Did the extent to which people used social networks - especially Twitter - really reflect how much they supported - or not - the public-health measures put in place during the COVID-19 pandemic? Quebec health experts Hélène Carabin and José Denis-Robichaud , helped by Erin Rees , who specializes in risk assessment at the Public Health Agency of Canada, went looking for answers to that question.

PUM launches a collection of comic strips. The first two volumes address the problems of access to vaccination during the pandemic and the sociology of young people in public places. A new collection entitled "Enquêtes scientifiques" is being launched this autumn by Presses de l'Université de Montréal (PUM), offering an original and accessible approach to disseminating scientific approaches in the form of comic strips.

The effects of rapid exposure to alcohol in early pregnancy - when a woman consumes as many as six drinks in an hour - can be detected in the placenta, an UdeM study on mice suggests. The effects of alcohol exposure on an embryo prior to implantation in the uterus can be detected in the late-gestation placenta, according to new research by Université de Montréal scientists.

Oct. 10-11, campus is open to McGill students, employees and essential visitors. Most classes are in-person. See Campus Public Safety website for details. Les 10 et 11 octobre, le campus est accessible aux étudiants et au personnel de l'Université, ainsi qu'aux visiteurs essentiels. La plupart des cours ont lieu en présentiel.

To help clinical staff choose the right drug against a fungal infection, researchers have classified the protective effects of around 4,000 mutations of a pathogenic fungus. Only four classes of antifungal drugs currently exist, and pathogen resistance to these drugs complicates treatment. A research team has identified resistance mutations in the fungus Candida albicans , the most common cause of fungal infections, for six widely used clinical drugs belonging to the azole class.

Findings have significant implications for understanding speech production in people with hearing loss, especially those using cochlear implants. A McGill University study has shown that hearing plays a crucial role in how people coordinate and control speech movements in real-time. Published in the Journal of the Acoustical Society of America (JASA), the research shows that when people cannot hear their own speech, even briefly, their ability to move their jaw and tongue in a coordinated manner is impaired.

A new study has found that 29 per cent of people in Ontario who undergo a surgical procedure called endometrial ablation will have a subsequent hysterectomy to remove the entire uterus within 15 years. Researchers from the Institute for Clinical Evaluative Sciences, known as ICES, Western's Schulich School of Medicine & Dentistry and Lawson Health Research Institute examined 76,446 patients who were followed for 15 years, addressing the question of surgical interventions after a first endometrial ablation (EA).

A discovery by scientists at the IRCM and the University of Pennsylvania leads to a better understanding of the role of the cytoskeleton in the neurological disorder of mirror movements. A team of Canadian and American scientists has made a promising breakthrough in understanding the origins of a mysterious neurological disorder known as mirror movements.

A new study by researchers in Canada and France provides insight into how a particularly severe form of epilepsy - as well as autism spectrum disorder - develops. What are the molecular and cellular mechanisms whereby some babies develop epileptic encephalopathies and autism spectrum disorder? That's what researchers in Canada and France set out to uncover - and they think they've found and answer.

Faculty of Arts researchers' work finds that girls and non-binary youth who experience teen dating violence are at elevated risk. It's well-known that adults who are victims of intimate-partner violence are also often victims of traumatic brain injury, including concussions. But whether this association exists in younger people who experience teen dating violence (TDV) has not been examined.
