Use of the Revised Second Victim Experience and Support Tool to Examine Second Victim Experiences of Respiratory Therapists.

Background: Respiratory therapists (RTs) work alongside allied health staff, nurses, and physicians during stressful and traumatic events that can be associated with emotional and physiological implications known as second victim (SV) experiences (SVEs). This study aimed to evaluate SVEs of RTs, including both positive and negative implications.

Methods: RTs within a large academic health care organization across Minnesota, Wisconsin, Florida, and Arizona were asked to participate in an anonymous survey that included the validated Second Victim Experience and Support Tool-Revised to assess SVEs as well as desired support services.

Neuregulin1 modulation of experimental autoimmune encephalomyelitis (EAE).

Neuregulin1 (NRG1) is a differentiation factor that regulates glial development, survival, synaptogenesis, axoglial interactions, and microglial activation. We previously reported that a targeted NRG1 antagonist (HBD-S-H4) given intrathecally, reduces inflammatory microglial activation in a spinal cord pain model and a neurodegenerative disease mouse model in vivo, suggesting that it may have effects in neuroninflammatory and neuronal disorders. We hypothesized that expression of HBD-S-H4 in the central nervous system (CNS) could reduce disease severity in experimental autoimmune encephalomyelitis (EAE), a widely used animal model for multiple sclerosis (MS).

Slowing disease progression in the SOD1 mouse model of ALS by blocking neuregulin-induced microglial activation.

There are no effective treatments to slow disease progression in ALS. We previously reported that neuregulin (NRG) receptors are constitutively activated on microglia in the ventral horns in both ALS patients and SOD1 mice and in the corticospinal tracts of ALS patients, and that NRG receptor activation occurs prior to significant clinical disease onset in SOD1 mice. Here, we hypothesize that blocking NRG signaling on microglia would slow disease progression in SOD1 mice using a targeted NRG antagonist (HBD-S-H4).

Folate Receptor Alpha Upregulates Oct4, Sox2 and Klf4 and Downregulates miR-138 and miR-let-7 in Cranial Neural Crest Cells.

Prenatal folic acid (FA) supplementation prevents neural tube defects. Folate receptor alpha (FRα) is critical for embryonic development, including neural crest (NC) development. Previously we showed that FRα translocates to the nucleus in response to FA, where it acts as a transcription factor.
