Current State of Genomics in Nursing: A Scoping Review of Healthcare Provider Oriented (Clinical and Educational) Outcomes (2012-2022).

In the 20 years since the initial sequencing of the human genome, genomics has become increasingly relevant to nursing. We sought to chart the current state of genomics in nursing by conducting a systematic scoping review of the literature in four databases (2012-2022). The included articles were categorized according to the Cochrane Collaboration outcome domains/sub-domains, and thematic analysis was employed to identify key topical areas to summarize the state of the science. Of 8532 retrieved articles, we identified 232 eligible articles. The articles primarily reported descriptive studies from the United States and other high-income countries (191/232, 82%). More than half (126/232, 54.3%) aligned with the "healthcare provider oriented outcomes" outcome domain. Three times as many articles related to the "knowledge and understanding" sub-domain compared to the "consultation process" subdomain (96 vs. 30). Five key areas of focus were identified, including "nursing practice" (50/126, 40%), "genetic counseling and screening" (29/126, 23%), "specialist nursing" (21/126, 17%), "nurse preparatory education" (17/126, 13%), and "pharmacogenomics" (9/126, 7%). Only 42/126 (33%) articles reported interventional studies. To further integrate genomics into nursing, study findings indicate there is a need to move beyond descriptive work on knowledge and understanding to focus on interventional studies and implementation of genomics into nursing practice.

"Walking in Their Shoes": The effects of an immersive digital story intervention on empathy in nursing students.

AIM: To evaluate the effects of a novel, immersive digital story intervention on empathy. DESIGN: A randomized trial with three phases. RESULTS: A total of 238 2nd year nursing students were recruited between May 2018 and December 2019. At baseline, no significant differences in empathy between the groups were found (p = .760). However, at post-test, empathy was significantly higher in the intervention group (M: 118.76, SD: 10.65) than it was in the control group (M: 114.60, SD: 15.40) (p = .012). At follow-up, there were no significant differences in empathy between the groups (p = .364). CONCLUSION: The intervention resulted in an immediate increase in empathy in nursing students. However, further development of effective intervention delivery modes and fundamental redesign of the intervention itself would be needed to sustain this improvement over the long term.

The first competency based framework in genetics/genomics specifically for midwifery education and practice.

This paper details a competency framework to help address the need for structured guidance around genetic and genomic education and training for midwives. A one-day expert panel consensus meeting was convened to review and revise a previously published joint framework for nurses, midwives and health visitors. Fifteen midwives from practice, management, education and policy and three genetic counsellors (two with midwifery backgrounds) attended. An in-depth knowledge of genetics/genomics was not a requirement. Personal narratives covering a range of experiences across the pre- and post-natal periods were used to stimulate discussion and debate. Identified themes were mapped to the original framework to identify gaps and differences. Inclusion of additional themes into the new framework was voted upon. All original competencies were found to be valid but required amendment in order to focus specifically on the role of the midwife and the needs of the mother, child and wider family. Revisions have resulted in a framework that is more directive and which addresses the time-critical nature of information-giving, decision-making, testing and referral that are crucial components of midwifery practice. Learning outcomes and practice indicators offer educators and trainers a means of developing student/staff knowledge and skills over time and with increasing experience.

NIPBL, encoding a homolog of fungal Scc2-type sister chromatid cohesion proteins and fly Nipped-B, is mutated in Cornelia de Lange syndrome.

Cornelia de Lange syndrome (CdLS) is a multiple malformation disorder characterized by dysmorphic facial features, mental retardation, growth delay and limb reduction defects. We indentified and characterized a new gene, NIPBL, that is mutated in individuals with CdLS and determined its structure and the structures of mouse, rat and zebrafish homologs. We named its protein product delangin. Vertebrate delangins have substantial homology to orthologs in flies, worms, plants and fungi, including Scc2-type sister chromatid cohesion proteins, and D. melanogaster Nipped-B. We propose that perturbed delangin function may inappropriately activate DLX genes, thereby contributing to the proximodistal limb patterning defects in CdLS. Genome analyses typically identify individual delangin or Nipped-B-like orthologs in diploid animal and plant genomes. The evolution of an ancestral sister chromatid cohesion protein to acquire an additional role in developmental gene regulation suggests that there are parallels between CdLS and Roberts syndrome.

A giant novel gene undergoing extensive alternative splicing is severed by a Cornelia de Lange-associated translocation breakpoint at 3q26.3.

Cornelia de Lange syndrome (CdLS) is a rare developmental malformation syndrome characterised by mental handicap, growth retardation, distinctive facial features and limb reduction defects. The vast majority of CdLS cases are sporadic. We carried out a high density bacterial artificial chromosome (BAC) microarray comparative genome hybridisation screen but no evidence was found for a consistent pattern of microdeletion/microduplication. As an alternative, we focused on identifying chromosomal regions spanning associated translocation breakpoints. We prioritised the distal 3q region because of the occurrence, in a classical CdLS patient, of a de novo balanced translocation with a breakpoint at 3q26.3 and of reports of phenotypic overlap between cases of mild CdLS and individuals trisomic for the 3q26-q27 region. We show that the 3q26.3 breakpoint severs a previously uncharacterised giant gene, NAALADL2, containing at least 32 exons spanning 1.37 Mb. Northern blot analysis identified up to six different transcripts in the 1-10 kb range with strongest expression in kidney and placenta; embryonic expression was largely confined to duodenal and stomach endoderm, mesonephros, metanephros and pancreas. Transcript analysis identified extensive alternative splicing leading to multiple 5' and 3' untranslated regions and variable coding sequences. Multiple protein isoforms were defined by different N-terminal regions (with at least four alternative initiating methionine codons), and by differential protein truncation/use of alternative C-terminal sequences attributable to alternative splicing/polyadenylation. Outside the N-terminal regions, the predicted proteins showed significant homology to N-acetylated alpha-linked acidic dipeptidase and transferrin receptors. Mutation screening of NAALADL2 in a panel of CdLS patient DNA samples failed to identify patient-specific mutations. We discuss the possibility that the 3q26.3 translocation could nevertheless contribute to pathogenesis.
