Outcomes of peer mentorship for people living with spinal cord injury: perspectives from members of Canadian community-based SCI organizations

ABSTRACT:

Study design

A generic qualitative design.

Objectives

To obtain a deeper understanding of the outcomes of spinal cord injury (SCI) peer mentorship programs delivered by community-based organizations.

Setting

Peer mentorship programs of community-based SCI organizations

Methods

We interviewed 36 individuals who shared their experiences of SCI peer mentorship from the perspective of a peer mentee, peer mentor, or family member of a peer mentee/mentor, or staff of SCI community-based organizations. Interview data were analyzed using an inductive thematic analysis approach.

Results

Four overarching themes with sub-themes were identified. (1) Positive outcomes for mentees such as understanding, emotional outlet/psychological support, inspiration/hope, and belonging. (2) Positive outcomes for mentors such as gaining gratitude, confidence, pride, and personal growth. (3) Reciprocity in positive/negative outcomes for mentors and mentees, such as shared learning and a lack of connection. (4) Negative outcomes for mentors such as impact of negativity, emotional toll, and time/energy demands.

Conclusions

Peer mentorship programs delivered by community-based SCI organizations are important, impactful resources for individuals with SCI who engage in these programs. These results provide insights into the variety of positive and negative outcomes linked with these programs.

Project description:The spinal cord after injury shows altered transcription in numerous genes. We tested in a pilot study whether the nucleus raphé magnus, a descending serotonergic brainstem region whose stimulation improves recovery after incomplete spinal cord injury, can influence these transcriptional changes. Rats received 2 hours of low-frequency electrical stimulation in the raphé magnus three days after an impact contusion at segment T8. Comparison groups lacked injuries or activated stimulators or both. Immediately following stimulation, spinal cords were extracted, their RNA transcriptome sequenced, and differential gene expression quantified. Confirming many previous studies, injury primarily increased inflammatory and immune transcripts and decreased those related to lipid and cholesterol synthesis and neuronal signaling. Stimulation plus injury, contrasted with injury alone, caused significant changes in 43 transcripts (39 increases, 4 decreases), all protein-coding. Injury itself decreased only four of these 43 transcripts, all reversed by stimulation, and increased none of them. The non-specific 5-HT7 receptor antagonist pimozide reversed 25 of the 43 changes. Stimulation in intact rats principally caused decreases in transcripts related to oxidative phosphorylation, none of which were altered by stimulation in injury. Gene ontology (biological process) annotations comparing stimulation with either no stimulation or pimozide treatment in injured rats highlighted defense responses to lipopolysaccharides and microorganisms, and also erythrocyte development and oxygen transport (possibly yielding cellular oxidant detoxification). Connectivity maps of human orthologous genes generated in the CLUE database of perturbagen-response transcriptional signatures showed that drug classes whose effects in injured rats most closely resembled stimulation without pimozide include peroxisome proliferator-activated receptor agonists and angiotensin receptor blockers, which are reportedly beneficial in spinal cord injury. Thus, the initial transcriptional response of injured spinal cord to raphé magnus stimulation is upregulation of genes that in various ways are mostly protective, some probably located in recently arrived myeloid cells.
