Women With Cervical Cancer May Have Increased Risk of Injury During Diagnostic Workup

Among women participating in cervical cancer screening in Sweden, those with a diagnosis of invasive cervical cancer had an increased risk of iatrogenic injuries (as a consequence of medical intervention) and non-iatrogenic injuries (caused by accidents and self-harm) requiring hospitalization, according to results published in Cancer Epidemiology, Biomarkers & Prevention.

Microscopic bone discovery holds promise for implants and bone diseases

A multidisciplinary team of researchers at McMaster University have discovered a structural feature of human bone that has never been studied before under a microscope, bringing scientists closer to advancing bone implants and treatments for bone diseases. Using a plasma focused ion beam microscope at the Canadian Centre for Electron […]

Study shows vitamin C prevents ulcer-related amputations

Ulcers are open wounds that fail to heal. They are caused or exacerbated by poor blood and nerve supply and in the case of foot ulcers, bad feet architecture. In severe cases, they can lead to amputation and there are an estimated 8,000 preventable foot amputations in Australia every year. […]

Hand-held device lets patients monitor their own blood for cancer biomarkers

Researchers at McMaster and Brock universities have created the prototype for a hand-held device to measure a biomarker for cancer, paving the way for home-based cancer monitoring and to improve access to diagnostic testing. The device works much like the monitors that people with diabetes use to test their blood-sugar […]

Diagnosing Parkinson’s disease with skin samples could lead to earlier detection

New research shows a simple skin test can accurately identify Parkinson’s disease, demonstrating for the first time the feasibility of the method. Currently diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy, Parkinson’s disease is commonly misdiagnosed early in the disease course, complicating clinical trials of potential […]

Reviving cells after a heart attack

Extracellular vesicles (EVs), nanometer-sized messengers that travel between cells to deliver cues and cargo, are promising tools for the next generation of therapies for everything from autoimmune and neurodegenerative diseases to cancer and tissue injuries. EVs have already been shown to help heart cells recover after a heart attack, but […]
