Prehospital Trauma Compendium: Vasopressors in Trauma - a Position Statement and Resource Document of NAEMSP.

Acutely injured trauma patients may develop shock from several potential mechanisms, including hypovolemic shock from hemorrhage, neurogenic shock from traumatic brain injury (TBI) or spinal cord injury, obstructive shock from tension pneumothorax or pericardial tamponade, or a mix of several of these mechanisms. Regardless of the cause, restoration of adequate perfusion is of critical importance to reduce the morbidity and mortality of trauma patients with shock. Multiple interventions including hemorrhage control, volume resuscitation with intravenous fluids or blood products, and pleural decompression procedures are used to address some of these issues and are discussed elsewhere in the trauma compendium.

Newly defined neural population in lateral amygdala is responsible for circadian rhythms in anxiety and touch sensitivity.

New work by Mark Wu's group in this issue of Neuron indicates that a neural population within the lateral amygdala, defined by the expression of mWAKE, functions as a crucial circadian oscillator to drive circadian rhythms in anxiety and touch sensitivity.

Optical Genome Mapping (OGM) Identifies Multiple Structural Variants in a Case With Atypical Phelan-McDermid Syndrome.

Here we describe a neonate exhibiting hypotonia, macrocephaly, renal cysts, and respiratory failure requiring tracheostomy and ventilator support. Genetic analysis via rapid genome sequencing (rGS) identified a loss on chromosome 4 encompassing polycystin-2 (PKD2) and a loss on chromosome 22 encompassing SH3 and Multiple Ankyrin Repeat Domains 3 (SHANK3), indicative of Phelan-McDermid syndrome. Further analysis via traditional karyotyping, Optical Genome Mapping (OGM), and PacBio long-read sequencing revealed a more complex landscape of chromosomal rearrangements in this individual, including a balanced 3;12 translocation, and an unbalanced 17;22 translocation.
