Other related therapies, in addition to a next generation platform technology, are in preclinical development. The next generation platform from Sentman's laboratory combines CAR T cells with another technology they developed called TCR-inhibiting molecules . TIMs are made to allow CAR therapy to be used with T cells from healthful donors yet avoid Graft-versus-Host-Disease . If successful, the TIM/CAR approach will reduce time to treatment, simplify logistics, and significantly decrease costs.‘This is actually the first study to show that caregivers of individuals who die in ICUs are in an elevated risk for developing PTSD,’ wrote the authors, led by Alexi Wright, MD, a medical oncologist and outcomes researcher at Dana-Farber. The American Medical Association Glossary defines PTSD as ‘feelings of anxiety experienced after an especially frightening or nerve-racking event, such as recurring dreams, difficulty sleeping, and a feeling of isolation.’ Furthermore, families and family members of patients who died in a healthcare facility, though not in an ICU, had been at higher threat of developing Prolonged Grief Disorder , an intense and disabling form of grief which lasts more than 6 months.
