Researchers at the James P. Allison Institute™ at the University of Texas MD Anderson Cancer Center have discovered a new gene expression signature in tumors that helps identify patients with metastatic castration-resistant prostate cancer (mCRPC) who are more likely to experience durable benefits from combination immunotherapy treatment. Results of the Phase 2 CheckMate 650 study; nature communicationsdemonstrate that an investigational combination of the immune checkpoint inhibitors ipilimumab and nivolumab achieved antitumor responses in a proportion of patients with chemotherapy-resistant disease. Using the unique capabilities of the Allison Institute’s immunotherapy platform, researchers discovered an immune signature associated with improved overall survival.…

Conclusion: A dual-threshold model for measuring the pancreatic tumor marker serum carbohydrate antigen 19-9 (CA19-9) identified patients with pancreatic cancer who had low CA19-9 levels but had high-risk disease due to genetic mutations that impaired their ability to produce this biomarker. Journal in which the study was published: clinical cancer researchJournal of the American Association for Cancer Research (AACR) author: Yung-Yeh Su, MD, PhD, research assistant and attending physician at the National Institutes of Health, National Cheng Kung University Hospital, and Kaohsiung Medical University Hospital, Taiwan, and senior author of this study background: Pancreatic ductal adenocarcinoma is a highly lethal…

New Curtin University-led research has found that siblings of people with neurodevelopmental disabilities living in regional and remote areas of Australia are more likely to suffer from lower levels of well-being and feel overlooked. The study, involving researchers from Kids Research Institute Australia, surveyed siblings aged 16 to 30 who currently or previously lived in non-urban areas about factors that influence their well-being, including resilience, social support and general family functioning. Most participants had a sibling with autism, but other neurodevelopmental disorders included attention deficit hyperactivity disorder, fetal alcohol spectrum disorder, Down syndrome, and intellectual disability. The researchers found that…

Reusable catheters are just as safe for patients as disposable catheters and do not increase the risk of urinary tract infections, a new study has found. Thousands of people use the device to empty their bladders an average of four times a day, and the plastic tube is used only once before being thrown away. Researchers at the University of Southampton followed hundreds of patients for a year to determine the health impact of reusable intermittent urinary catheters compared to disposable catheters. They found that people who tested reusable catheters used 35% fewer antibiotics compared to disposable-only catheters. Groundbreaking research…

The Ibsen-commissioned study identified widespread problems with the transition from pediatric to adult care, and drug companies are calling for more resources to help people manage the transition. Ibsen, which sells several treatments to children and young adults, partnered with Harris Poll to survey about 1,500 people between the ages of 14 and 26, as well as about 1,500 parents, 200 primary care providers and 200 pediatricians. A US survey found that 71% of young people felt the adult healthcare system was confusing, and two-thirds said they wished they had been better prepared to leave pediatric medicine. This concern was…

Our bones don’t begin deep within our bodies. Not long after the first complex animals took shape, they began with skin. Skin bones have remained a recurring motif in evolution ever since. But we still know surprisingly little about them. Why do they appear repeatedly in different groups, such as turtles, crocodiles, lizards, snakes, and even dinosaurs? And was there a single ancestor with skin bones that produced them all? In a new study published in the Biological Journal of the Linnean Society, we investigated this question. We combined fossil evidence with modern computational tools to reconstruct the evolution of…

Finnish researchers have achieved a major breakthrough in ultra-sensitive measurement technology by detecting amounts of energy smaller than 1 zeptjoule, or less than one billionth of a joule. This breakthrough could improve quantum computing technology, support the search for dark matter, and ultimately make it possible to count the number of individual photons. Quantum mechanics operates on incredibly small scales, and scientists are constantly developing more precise tools to measure and control phenomena such as photons (particles that carry light). Improved precision could open the door to more powerful quantum devices and new ways to study some of the universe’s…

The Mediterranean Sea is widely recognized as having a low tsunami risk. History and recent modeling techniques show that destructive waves have already hit the coast of France and may do so again. The results of projects carried out in Nice and along the Cote d’Azur demonstrate why predictive and preventive evacuation measures are the only truly effective means of saving lives. Tsunamis were once known as high waves. tsunami France? tsunami In Italy, these are one of the most destructive natural phenomena. Caused by earthquakes, underwater landslides, and volcanic eruptions, they quickly spread over long distances and then release…

A new study provides evidence that middle-aged and older adults who consume more ultra-processed foods tend to be less alert and at higher risk of developing dementia. The results of this study show that small daily increases in intake of these foods are associated with measurable decreases in attention span, even if you eat an otherwise healthy diet. The study was published in the journal Alzheimer’s disease and dementia: diagnosis, evaluation, and disease monitoring. Lead author Barbara Cardoso, a researcher at Monash University’s School of Nutrition, Dietetics and Food and the Victoria Heart Institute, said the study supports a clear…

Major studies suggest that pregnancy increases cardiovascular risk across all maternal ages and that older patients face more events due to higher baseline risk, rather than primarily through age-related pregnancy-specific mechanisms. Study: Maternal age and pregnancy-related cardiovascular complications. Image credit: Agatha Jennifer / Shutterstock Older maternal age does not by itself exacerbate pregnancy-specific cardiovascular complications during pregnancy. Rather, pregnancy appears to uniformly amplify women’s baseline cardiovascular risk, as reported in a new study published in the journal Physiology. nature communications. Background of maternal age and cardiovascular risk Pregnancy-related cardiovascular complications are major risk factors for maternal mortality. Approximately 20-30% of…
