New machine algorithm could identify cardiovascular risk at the click of a button

Researchers developed an automated machine learning program to identify potential cardiovascular incidents and fall/fracture risks based on bone density scans. The algorithm shortened screening time and found moderate to high AAC levels in 58% of older individuals, placing them at high risk of heart attack and stroke.

Oral HER2-targeted therapy zongertinib demonstrates clinical benefit in advanced HER2-mutated lung cancer

The phase Ia/Ib Beamion LUNG-1 trial found that zongertinib elicited durable responses in patients with advanced, previously treated non-small cell lung cancer (NSCLC) harboring a HER2 mutation. The disease control rate was high across cohorts, with median progression-free survival ranging from 12.4 to 6.8 months.

Swim Across America grant funding of Memorial Sloan-Kettering Cancer Center clinical trial shows that immunotherapy alone could replace surgery, enabling patients to regain their organs and enhance their quality of life

A recent clinical trial funded by Swim Across America grant showed that immunotherapy can successfully replace surgery for mismatch repair-deficient (MMRd) solid tumors. This breakthrough treatment enabled 80% of patients to avoid surgery and regain their organs.

New research evaluates the ability of patients with adrenal crisis to complete emergency cortisol injections

A new study explores the ability of individuals with adrenal crisis to accurately and effectively administer emergency cortisol injections. Nearly half of those living with adrenal insufficiency are unable to self-administer life-saving injections during a medical emergency, highlighting the need for improved awareness and preparedness.

Researchers discover accelerated reaction between Criegee intermediates and water via roaming mechanism

Scientists have discovered a new pathway for the reaction of Criegee intermediates with water vapor, approximately 100 times faster than previously predicted. The 'roaming mechanism' driven by strong dipole-dipole interactions between molecules leads to a higher probability of reaction, revising our understanding of key atmospheric pro...

Climate change increases the risk of simultaneous wildfires

The risk of wildfires is increasing due to climate change, leading to overlapping fire weather seasons in the two regions. The number of simultaneous fire weather days has been increasing by one day per year for the past 40 years, with projections suggesting an increase of up to 29 days per year by mid-century.
