Cold weather exposure linked to increased risk of heart attacks

A nationwide study in Sweden reveals that short-term exposures to lower air temperature and cold spells are associated with an increased risk of myocardial infarction hospitalization after two-six days. Researchers found that this delay in hospitalizations suggests a delayed onset of cold-related impacts on MI risk.

Brigham-led clinical trial finds finerenone reduces worsening heart failure and cardiovascular death

A randomized, placebo-controlled trial found finerenone improved outcomes in patients with heart failure and mildly reduced or preserved ejection fraction. The drug also showed benefits regardless of the ejection fraction and even in patients on other approved therapies.

Asundexian inferior to apixaban for stroke prevention in atrial fibrillation

A phase III trial found that asundexian was inferior to apixaban in preventing stroke and systemic embolism in high-risk patients with atrial fibrillation. The trial also showed lower bleeding rates with asundexian, but this finding needs to be put into context with the stroke findings.

Accuracy verification methodology for CGH used for testing ultra-large aperture mirrors

Researchers have developed a new accuracy verification methodology for ultra-large aperture mirrors using computer-generated hologram (CGH), achieving nanometer-level accuracy. The method uses an equivalent element to test the mirror's surface shape accuracy, overcoming aperture limitations and enabling reliable testing.

Wearable heart monitor increases diagnosis of irregular heart rhythm

A large study found that wearable heart monitors increased diagnoses of atrial fibrillation by 52% compared to usual care. However, it did not lead to a significant reduction in hospitalizations due to stroke. The study's findings provide inconclusive data on the effectiveness of screening for atrial fibrillation in reducing stroke risk.

Genomic analyses of prairie chickens cast doubt on species classifications

A recent genomics study of prairie chickens in five states has found evidence of hybridization between the two species, with no clear indication of genetic problems. The study suggests that these species may belong to the same species and challenges wildlife management nationwide.

Hawk defies expectations in the face of habitat decline

A recent study published in The Journal of Raptor Research found that Ferruginous Hawk populations are increasing in California, contrary to declining trends in other grassland bird species. Citizen science data analysis revealed a significant decrease in habitat quality yet an increase in hawk abundance across California.

Singapore scientists to use exosomes secreted by living cells to successfully target TKI-resistant cancer

Researchers from National Cancer Centre Singapore have successfully used exosomes to target squamous cell cancer tumours resistant to EGFR-TKIs. The study found that exosomes carrying a specific protein can increase sensitivity to TKIs in both lab and mouse models, providing new therapeutic solutions for patients with poor prognosis.

Promising treatment for incurable prostate cancer

Researchers at Flinders University and University of South Australia have discovered a potential breakthrough in treating the most aggressive forms of prostate cancer using CDKI-73, a novel drug inhibitor. The study found that CDKI-73 effectively blocks the growth of prostate cancer cells while sparing normal cells.
