Black Canadians face significant systemic barriers to donating critical blood

Black people in Canada who want to donate blood face barriers to doing so, despite a critical need for specific blood types to treat sickle cell disease, according to new research published in CMAJ.

Type 2 diabetes mechanisms differ significantly based on patient BMI

Research published today in Diabetologia by Amsterdam UMC and the University of Ghana reveals that type 2 diabetes manifests in two fundamentally different ways depending on a patient's body mass index (BMI).

Satellite DNA acts as a barcode for matching chromosome pairs

The body cells of humans and animals contain a double set of chromosomes. One half of the genetic material comes from the mother, the other stems from the father.

Bone density after reverse shoulder arthroplasty declines over time

Driven by the potential advantages in bone stock preservation and easier implant removal during revision surgery, the use of cementless short-stem implants in shoulder arthroplasty has increased in recent years.

Review outlines key strategies to reduce gynecologic cancer-related mortality

Low- and middle-income countries (LMICs) bear a disproportionate burden of gynecologic malignancies-cancers of the cervix, endometrium, ovary, vagina, and vulva.

Fruit fly brain inspires energy-efficient scent classification algorithm

In the animal kingdom, energy conservation is essential for survival. That's why our brains have evolved to be extremely energy and resource efficient at storing and processing information.

Nanoparticle vaccine offers long-lasting protection against multiple flu strains

A new, nanoparticle vaccine could one day grant patients immunity to the flu with fewer trips to the doctor and without health officials correctly guessing which flu strains will become dominant each year.

Combined bio-histological score prevents overtreatment in liver transplant patients

Long‑term outcomes after liver transplantation remain hampered by complications linked to intensive immunosuppression—infections, cardiovascular events, kidney dysfunction, and metabolic disorders affect 10% to 40% of recipients.

Shortages in ambulance staff increase emergency department death risk

Unexpected staff shortages in ambulance services are costing lives, with patients significantly more likely to die within 24 hours when ambulance crews are unexpectedly off sick, according to new research from the University of Surrey and the University of York.

Semaglutide’s heart benefits may partly involve reduced inflammation

A prespecified analysis of 17,604 SELECT participants found that higher baseline hsCRP was associated with greater risks of major cardiovascular events and death in people with overweight or obesity and established cardiovascular disease. Semaglutide produced rapid and sustained reductions in hsCRP, with changes emerging before substantial weight loss, although the study could not establish whether reduced inflammation directly mediated its cardiovascular benefits.

These simple fitness tests revealed which older adults had the lowest death risk

Objective fitness tests in 13,423 Taiwanese adults aged 65 years or older linked better balance, agility, lower-body strength, and cardiorespiratory fitness with lower all-cause mortality over a median seven years. A multidomain fitness index showed the strongest association, suggesting that simple performance tests may add useful information to conventional geriatric risk assessment.

Historic redlining continues limiting healthy food access, study finds

Bad housing, high crime and poor schools are more important than transportation or income when it comes to accessing healthy food in neighborhoods historically subjected to "redlining" - the now-illegal practice once used to refuse loans, insurance or mortgages to people in certain neighborhoods that were disproportionately inhabited by racial and ethnicity minorities.

Scientists uncover tRNA changes driving Chagas parasite transformation

The Chagas disease parasite (Trypanosoma cruzi) undergoes a major transformation throughout its life cycle in order to infect humans and other mammals.

New AI model reveals hidden code behind gene activation

Precise activation of tens of thousands of genes is critical for healthy development and growth. Specialized segments of our DNA are responsible for carefully orchestrating genetic sequences that result in the production of enzymes, hormones, proteins and other crucial components underlying cell structure and function.

Deliverome project maps cell surface proteins for better drug delivery

For a new drug to work in the human body, it must make its way to the exact cell type where it's needed and then, in many cases, get inside the cells.

New 3D mapping technology reveals how hair follicles form over time

In a new research report, scientists at Johns Hopkins Medicine say they have developed a technology that allows them to capture a 3D molecular "snapshot" of hundreds of hair follicles as they develop and then reconstruct the fourth dimension - time - to effectively create a stop-motion animation of how this organ forms.

Study highlights strengths and barriers of remote heart failure care

Interviews with patients hospitalized for heart failure, caregivers, providers, and organizational leaders highlighted several strengths of Mighty Heart (a major clinical trial examining the effectiveness of in home and telehealth-enabled visits from paramedics) that may support its adoption and implementation across health systems, a Columbia Nursing-led study finds.
