Scientists have identified two coffee compounds, kahweol acetate and cafestol, which inhibit the growth of prostate cancer cells in cell culture and animal models. The study's findings suggest that these compounds may be used to treat drug-resistant prostate cancer, with further investigation needed.
Researchers used HBV genome sequences to infer ancient human migration into Australia, revealing unique viral strain and geographical connections. The study adds weight to the theory of mainland Aboriginal population separation at least 59 thousand years ago.
A commonly used heart drug, nifedipine, is associated with an increased risk of out-of-hospital sudden cardiac arrest, particularly at high doses. The study analyzed data from large registries and found no risk association with amlodipine.
Men undergoing hormonal treatment after prostate removal are 80% more likely to suffer from depression, according to a study presented at the European Association of Urology congress. The treatment is given to control tumor growth, but it may also affect men's well-being.
A new study found that the Apple Watch can detect atrial fibrillation (AFib) in people who have an irregular heartbeat. The study showed that the watch's algorithm was accurate 84% of the time, and nearly half of those notified went on to seek medical care.
Researchers found that systematic depression screening after a heart attack did not impact patients' quality of life. Depression was identified in about 7% of screened patients, and interventions such as medication, phone-based psychotherapy sessions, or a combination both were shown to be effective in reducing depressive symptoms.
Researchers developed PB2452, a monoclonal antibody fragment that reverses ticagrelor's antiplatelet effects within five minutes and sustains reversal for over 20 hours. The study found immediate and sustained reversal of ticagrelor's effects, with no serious adverse events or infusion reactions.
Transcatheter aortic valve replacement (TAVR) significantly reduces the primary endpoint of death, stroke, and re-hospitalizations in patients with severe, symptomatic aortic stenosis at low surgical risk. TAVR also shows lower rates of mortality, stroke, and repeat hospitalizations compared to surgery.
Scientists at University of Sydney have successfully used 50-year-old ram sperm to impregnate 34 Merino ewes, demonstrating the viability of long-term frozen storage. The resulting live birth rate was comparable to that of recently frozen semen.
A new study reveals that patients with prostate, bladder, or kidney cancers who have had psychiatric care prior to treatment are at a greater risk of dying. The research also found an increased suicide risk among these patients, even after adjusting for previous mental health treatment.
A novel electrocardiogram method uses signals from the ear and hand to detect atrial fibrillation and prevent strokes. The new technique paves the way for a single-lead ECG wearable device that could be used by drivers, athletes, and the military.
A new study suggests that transcatheter aortic valve replacement (TAVR) is a safe and effective option for patients with bicuspid aortic valve stenosis, particularly those at intermediate or high risk for open heart surgery. While patients with a bicuspid valve had a higher risk of stroke after TAVR, the overall mortality rate was simi...
A recent study reveals that transposable element insertions drive rapid phenotypic variation in plants, enabling them to adapt to novel environments. Researchers found that transposable elements are enriched in the gene promoter regions of a plant species with limited genetic variation, associated with changes in gene expression.
A Cleveland Clinic-led study found that an absorbable antibiotic envelope can significantly reduce major infections in cardiac device implantations. The envelope was shown to cut the rate of infections by 40% compared to standard care.
The final results of MOMENTUM 3 show that the HeartMate 3 left-ventricular assist device markedly reduced re-operation due to pump malfunctions, lowering risk of bleeding events and strokes. The study found significant reductions in pump-related thrombosis, strokes and mucosal bleeding compared to the previous generation of cardiac pumps.
A study of nearly 500,000 women found that taking paracetamol or other painkillers during pregnancy increases the risk of asthma in children, but the risk is similar when other types of painkillers are used. The research suggests that another factor linked to painkiller use and asthma risk may be chronic pain and stress.
Results from the PARTNER 3 trial demonstrate that low-risk patients with severe aortic stenosis can significantly benefit from minimally invasive TAVR, leading to shorter recovery times and lower complication rates. This groundbreaking procedure has the potential to transform treatment options for patients with heart disease.
The Sodré astrolabe is the oldest known mariner's astrolabe, dating back to 1496-1501. It has been certified as the earliest verifiable example of a transitional instrument between classic planispheric and open-wheel astrolabes.
A randomized trial of Smart Choices 4 Teens, an online family prevention program, found significant reductions in teen alcohol use and related problems. The program decreased drinking days, amount consumed, and parent-teen communication about social host laws.
