Caregiver perspectives of scoliosis surgery for children with cerebral palsy: a qualitative study.

PURPOSE: To explore the perspectives of primary caregivers of children with cerebral palsy (CP) who had spinal surgery for scoliosis. MATERIALS AND METHODS: A qualitative study was conducted using semi-structured interviews and guided by qualitative description methodology. Participants were caregivers of children with CP aged 5-18, who had undergone spinal surgery for scoliosis in Australia. The research team included a parent with lived experience. RESULTS: Fourteen participants (8 biological mothers), aged 40-49 years, completed online semi-structured interviews. Four themes were identified emerged. Life with a child with CP underpinned all experiences which were founded on familiarity with their child, medical procedures, and hospitalisation. Three subthemes were parents are the experts in knowing their child, children are vulnerable, and impact on caregivers. Theme 2 involved the significance of decision making to proceed with surgery. Theme 3 underscored a need to be prepared for the surgical journey and, in Theme 4, participants spoke of needing to expect the unexpected. CONCLUSION: The findings highlight the importance of understanding caregiver experiences and can help inform health professionals and other families in the decision-making process, preparing for and navigating spinal surgery.

Spinal surgery for scoliosis in children with cerebral palsy is a major surgery and poses substantial challenges for the family.Understanding the magnitude of the decision for families to proceed with surgery will equip health professionals to adequately support and partner with families.Detailed information and extensive preparation are necessary for families to proceed with and navigate surgery, the hospital stay and to return home and to the community.

Sectioning and Counting of Motor Neurons in the L3 to L6 Region of the Adult Mouse Spinal Cord.

Histology is the study of the microscopic structure of tissues. This protocol permits the generation of frozen transverse sections of lumbar spinal cord regions L3 to L6. It enables counting of murine ventral horn lumbar motor neurons in a reproducible manner. Methods include spinal column dissection, hydraulic extrusion, and histological processing. The preparation for cryo-sectioning includes embedding lumbar spinal cord in optimal cutting temperature (OCT) medium. The correct orientation of the tissue is critical as calculating the amount of tissue to discard saved time overall. Specific details regarding section thickness and mounting are described. These requirements not only allow optimum coverage of specific regions but also ensure that no individual motor neuron was counted twice. The Nissl bodies of the motor neurons were stained using gallocyanin. The sections obtained are all of a comparable area and quality assurance is consistent. The specificity of the staining enables the scientist to identify and reliably quantify lumbar motor neurons. © 2022 The Authors. Current Protocols published by Wiley Periodicals LLC.

Generation and analysis of innovative genomically humanized knockin SOD1, TARDBP (TDP-43), and FUS mouse models.

Amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) is a fatal neurodegenerative disorder, and continued innovation is needed for improved understanding and for developing therapeutics. We have created next-generation genomically humanized knockin mouse models, by replacing the mouse genomic region of Sod1, Tardbp (TDP-43), and Fus, with their human orthologs, preserving human protein biochemistry and splicing with exons and introns intact. We establish a new standard of large knockin allele quality control, demonstrating the utility of indirect capture for enrichment of a genomic region of interest followed by Oxford Nanopore sequencing. Extensive analysis shows that homozygous humanized animals only express human protein at endogenous levels. Characterization of humanized FUS animals showed that they are phenotypically normal throughout their lifespan. These humanized strains are vital for preclinical assessment of interventions and serve as templates for the addition of coding or non-coding human ALS/FTD mutations to dissect disease pathomechanisms, in a physiological context.
