Through intricate experiments designed to account for sex-specific differences, scientists at Scripps Research have collaborated to zero-in on certain changes in the brain that may be responsible for driving alcohol abuse among people with PTSD. In studies with rodents, researchers found that males and females exhibit their own distinct symptoms and brain features of PTSD and alcohol use disorder. Such differences are not typically accounted for in laboratory-based studies yet could lead to more successful clinical treatments.
Researchers have validated a new radiolabeled molecule that can be used with imaging tests to accurately detect and characterize brain injury.
A sizable research consortium coordinated by NTNU and St. Olavs Hospital will analyse large amounts of MRI exam data from around the world. The data will help researchers gain important new understanding about brain injuries in people who have had trauma to the head. The goal is to improve patient health care.
Among women participating in cervical cancer screening in Sweden, those with a diagnosis of invasive cervical cancer had an increased risk of iatrogenic injuries (as a consequence of medical intervention) and non-iatrogenic injuries (caused by accidents and self-harm) requiring hospitalization.
NUST MISIS material scientists have presented antibacterial nano-coatings based on boron nitride, which are highly effective against microbial pathogens (up to 99.99%). They can become a safe alternative to the usual antibiotics in implantology since they do not have typical negative side effects. The results of the work are published in the international scientific journal ACS Applied Materials & Interfaces.
CVB announces findings from a study, led by Stanford University professor, Amit Etkin, MD, PhD, which generates new evidence in support of a critical brain imaging biomarker, that may guide people who suffer from PTSD or MDD towards the most effective treatment. The study used advanced machine learning techniques on data from high density EEG signals to identify robust and distinct functional connectivity patterns in brain circuits enabling subtyping of patients, independent of clinical diagnosis.
When looking at media reports in three cities, half of victims were covered in the news, but a disproportionate amount of attention was given to less common circumstances and victims.
A new study of gun injuries and deaths in Ontario found that 68% of firearm-related deaths were from self-harm, and they most often occurred in older men living in rural regions, pointing to the need for targeted prevention efforts. The study is published in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/lookup/doi/10.1503/cmaj.200722.
Thin tissue grafts and flexible electronics have a host of applications for wound healing, regenerative medicine and biosensing. A new device inspired by an octopus's sucker rapidly transfers delicate tissue or electronic sheets to the patient, overcoming a key barrier to clinical application, according to researchers at the University of Illinois at Urbana-Champaign and collaborators.
COVID-19 presents a new and urgent opportunity to focus political will, federal investments, and global community on the vital imperative of suicide prevention. Suicide prevention in the COVID-19 era requires addressing not only pandemic-specific suicide risk factors, but also prepandemic risk factors.
