Our brains consist of soft matter bathed in watery cerebrospinal fluid inside a hard skull, and in Physics of Fluids, researchers describe studying another system with the same features, an egg, to search for answers about concussions. Considering that in most concussive brain injuries, the skull does not break, they wanted to find out if it was possible to break or deform the egg yolk without breaking the eggshell.
Researchers from the National Institutes of Health have discovered Jekyll and Hyde immune cells in the brain that ultimately help with brain repair but early after injury can lead to fatal swelling, suggesting that timing may be critical when administering treatment. These dual-purpose cells, which are called myelomonocytic cells and which are carried to the brain by the blood, are just one type of brain immune cell that NIH researchers tracked, watching in real-time as the brain repaired itself after injury.

Pediatric laryngotracheal stenosis (LTS), a narrowing of the airway in children, is a complex medical condition. While it can be something a child is born with or caused by injury, the condition can result in a life-threatening emergency if untreated.
Treatment, however, is challenging. Depending on the severity, doctors will use a combination of endoscopic techniques, surgical repair, tracheostomy, or deployment of stents to hold the airway open and enable breathing.

East Hanover, NJ. January 14, 2021. Ghaith Androwis, PhD, and Steven Kirshblum, MD, received a grant from BrainQ Technologies to study a potential treatment for arm and hand dysfunction in individuals with chronic spinal cord injury. The study is titled, The safety and effectiveness of the use of a brain-computer interface-based electromagnetic field treatment in the management of patients with chronic spinal cord injury: A pilot study.
Dr. Androwis is a research scientist in the Center for Mobility and Rehabilitation Engineering Research at Kessler Foundation. Dr. Kirshblum is senior medical officer and director of the Spinal Cord Injury Program for Kessler Institute for Rehabilitation, chief academic officer for the Select Medical R

New research from King s College London shows nearly half of Intensive Care Unit (ICU) staff are likely to meet the threshold for PTSD, severe anxiety or problem drinking during the COVID-19 pandemic.
Results from a study of ICU healthcare workers, published today in
Occupational Medicine, shows the stark impact of working in critical care during the COVID-10 pandemic. The researchers found poor mental health was common in many ICU clinicians although they were more pronounced in nurses than in doctors or other healthcare professionals.
Lead author, Professor Neil Greenberg, from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN), King s College London said:
