Biol Psychiatry Glob Open Sci

March 2025

Initiative on Stress, Trauma, and Resilience, Department of Psychiatry and Human Behavior, Warren Alpert Medical School, Brown University, Providence, Rhode Island.

Background: Mounting evidence suggests that mitochondria respond to psychosocial stress. Recent studies suggest mitochondrial DNA (mtDNA) deletions may be increased in some psychiatric disorders, but no studies have examined early-life stress (ELS) and mtDNA deletions. In this study, we assessed mtDNA deletions in peripheral blood mononuclear cells of medically healthy young adults with and without ELS.

Electroacoustic imaging is an imaging modality used to detect electric field energy distribution during electroporation, offering valuable guidance for clinical procedures, particularly in deep tissues. Traditionally, single-element piezoelectric transducers or arrays have been employed for this purpose. However, these piezoelectric sensors are sensitive to electromagnetic interference and require physical contact with the sample through a coupling medium, raising concerns for both clinical and preclinical applications.

Background: The American Association for the Surgery of Trauma (AAST) grading system for intestinal obstruction may be a useful measure of anatomic severity, but its construct validity has not yet been evaluated in patients with either large or small bowel obstruction, using the grade applicable at initial presentation (rather than after definitive management).

Materials And Methods: We conducted a retrospective case series of adult inpatients presenting with intestinal obstruction at our center during 2008-2014. We excluded patients without confirmed intestinal obstruction, those with obstruction secondary to a hernia, those who were treated for >24 hours at another hospital, and those with a previous encounter already included in the study.

Chimeric antigen receptor (CAR) T-cell therapy is a potentially life-saving treatment for children with relapsed/refractory B-cell hematologic malignancies, and remains an important investigational therapy for other childhood cancers. Yet, access to this class of therapies remains suboptimal through both commercial use and clinical trials, especially in children, adolescents, and young adults. Using a series of case-based discussions, we outline guidance on real-world medical decision-making, and offer potential solutions to enhancing access to CAR T-cell therapy as a treatment modality.
