A phase III clinical trial confirms the safety and efficacy of a moderately shortened course of radiation therapy for men with high-risk prostate cancer. The study found no significant differences in survival rates, side effects, or recurrence between 5-week and 8-week radiation therapy.
Researchers from University of South Australia found that porous silica can prevent fats and carbohydrates from being adsorbed in the body. Engineered particles of purified sand are designed to soak up digestive enzymes, fats, and sugars within the gastrointestinal tract.
A randomized, phase III clinical trial found that patients who receive technical explanations from medical physicists before treatment have lower anxiety levels and higher satisfaction rates. Medical physicist consults can significantly improve patient outcomes by reducing stress and anxiety related to radiation therapy.
A team at KAUST has created an ultrathin dielectric metalens that improves focusing capabilities and can be scaled down for integration with photonics equipment. The metalens, designed from a custom array of TiO2 nanopillars atop a DBR, offers negligible intrinsic loss and easy fabrication.
A new study by the University of Surrey found that London Underground stations have high levels of fine and coarse air pollution particles, exceeding World Health Organization guidelines. The research recommends improving ventilation on the London Underground to mitigate health risks.
Research using data from over 56,000 patients found that those on Medicaid, women, and minority groups are less likely to be offered regional anesthesia techniques. This disparity affects outcomes after surgery, including pain management and complications.
Research at the ANESTHESIOLOGY 2022 annual meeting found that preschool children experiencing emergence delirium post-surgery do not exhibit long-term behavioral changes. No measurable problems were observed three months after surgery.
Adults who use cannabis experience 14% more pain after surgery and consume 7% more opioids. The study analyzed 34,521 patients and found a significant association between cannabis use and postoperative pain.
A study by University of Cambridge researchers found that ineffective teacher training is the likely cause of failures in promoting children's physical health in schools. The review of 51 randomised control trials suggests that key ingredients like clear goals, regular feedback, and resources are often missing from teacher training.
Researchers found that American participants had the most positive perception of gene-edited food, while German participants saw it as less beneficial and riskier. Japanese participants' perceptions were intermediate between Germans and Americans. The study suggests that public attitudes towards emerging science are influenced by regul...
A study found that wearing green eyeglasses reduces pain-related anxiety and decreases opioid use in fibromyalgia patients. The treatment uses specially formulated lenses to filter specific wavelengths of green light, which stimulates pathways in the brain to manage pain.
Researchers identified carbon-dioxide-fixing cells from seawater and used Raman-spectroscopy to determine that they engage in photosynthesis. The study reveals that uncultured Pelagibacter spp., one of the most abundant SAR11 marine bacteria, can use light-powered metabolism for CO2 fixation in seawater.
A phase II trial suggests that radiation can reduce painful complications and hospitalizations, and possibly extend overall survival in patients with advanced cancers. The study found that treating asymptomatic lesions with radiation reduced skeletal-related events and extended overall survival compared to those who received no radiation.
In a first-in-human trial, FLASH radiation treatment was found safe and effective for pain relief in patients with bone metastases. The study showed significant pain relief in 7 out of 10 patients, with minimal side effects.
Researchers used transcranial ultrasound stimulation to confirm the anterior prefrontal-putamen circuit's role in stopping inappropriate responses. The circuit involves the right hemisphere's inferior frontal cortex, presupplementary motor area, and subthalamic nucleus.
