Multiple sclerosis (MS) is a chronic neurological disease characterized by nerve damage and consequent impairments in vision, movement, balance and mental function. In MS, the immune system mistakenly starts attacking myelin, the protective sheath that surrounds axons (i.e., nerve fibers) in the brain, spinal cord and optic nerves.

Macrophages, immune cells responsible for detecting damaged cells, germs or other debris in the central nervous system (CNS) and eliminating them, have been found to play a key role in MS...

Easy-to-use tool can identify high- and low-risk metastatic prostate cancer patients earlier

A new study published in Nature Communications provides a framework for researching whether earlier, model-guided treatment intensification can meaningfully improve survival for patients with aggressive disease.

“Early decline in prostate-specific antigen (PSA) to very low levels is one of the strongest predictors of long-term survival in metastatic prostate cancer. However, clinicians currently have to wait up to six months after starting therapy to see whether a patient achieves this favorable response. For patients who do not respond well, this delay may allow the cancer to progress and become more resistant to treatment,” said Soumyajit Roy, MD, a radiation oncologist at UH Seidman Cancer Center and first author of the study.

New BMI uses AI to reveal hidden metabolic disorders

New BMI reveals hidden metabolic disorders

Researchers at Leipzig University and the University of Gothenburg have developed a novel approach to assessing an individual’s risk of metabolic diseases such as diabetes or fatty liver disease more precisely. Instead of relying solely on the widely used body mass index (BMI), the team developed an AI-based computational model using metabolic measurements. This so-called metabolic BMI shows that people of normal weight with a high metabolic BMI have up to a fivefold higher risk of metabolic disease. The findings have been published in the journal Nature Medicine.

The conventional body mass index, calculated using height and weight, may indicate overweight but does not reflect how healthy or unhealthy body fat actually is...

Overlooked molecule points to new treatments for drug resistant fungal infections

Fungal infections kill millions of people each year, and modern medicine is struggling to keep up. But researchers at McMaster University have identified a molecule that may help turn the tide—butyrolactolA, a chemical compound that targets a deadly, disease-causing fungi called Cryptococcus neoformans.

Infections caused by Cryptococcus are extremely dangerous. The pathogen, which can cause pneumonia-like symptoms, is notoriously drug-resistant, and it often preys on people with weakened immune systems, like cancer patients or those living with HIV. And the same can be said about other fungal pathogens, like Candida auris or Aspergillus fumigatus—both of which, like Cryptococcus, have been declared priority pathogens by the World Health Organization.

Despite the threat, thou...
