Career decisions and aspirations of early-career nurses: Insights from a qualitative interpretative description study.

AIM: To explore the career decisions and aspirations of early-career registered nurses in New Brunswick, Canada. DESIGN: A qualitative study using an interpretive description approach was conducted. METHODS: Semi-structured one-on-one interviews were conducted with a purposive sample of nurses (n = 22) currently working in New Brunswick, Canada, with up to 5 years of experience from February to April 2022. RESULTS: Participants described diverse career paths and aspirations. Personal factors affecting these included the desire for meaningful work, career satisfaction, work-life balance, spending time with family, working in a preferred location, and finances. Professionally, working conditions were the dominant factor influencing early-career nurses' career decisions and aspirations. Participants described how short staffing, safety, support, and scheduling influenced their day-to-day work, mental and physical health, job and career satisfaction, and intent to leave. CONCLUSION: The findings highlighted the abundant and diverse career opportunities available to nurses early in their careers. Early-career nurses are interested in finding nursing positions with a high degree of person-job fit and value opportunities for ongoing professional education and growth. IMPACT: This study in New Brunswick, Canada, explores early-career nurses' career decisions and aspirations during nursing shortages and the pandemic, emphasizing the importance of person-job fit. Recommendations include improving working conditions and career pathways to enhance the sustainability of the nursing profession. REPORTING METHOD: Standards for Reporting Qualitative Research (SRQR). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Carbon materials and their metal composites for biomedical applications: A short review.

Carbon materials and their hybrid metal composites have garnered significant attention in biomedical applications due to their exceptional biocompatibility. This biocompatibility arises from their inherent chemical stability and low toxicity within biological systems. This review offers a comprehensive overview of carbon nanomaterials and their metal composites, emphasizing their biocompatibility-focused applications, including drug delivery, bioimaging, biosensing, and tissue engineering. The paper outlines advancements in surface modifications, coatings, and functionalization techniques designed to enhance the biocompatibility of carbon materials, ensuring minimal adverse effects in biological systems. A comprehensive investigation into hybrid composites integrating carbon nanomaterials is conducted, categorizing them as fullerenes, carbon quantum dots, carbon nanotubes, carbon nanofibers, graphene, and diamond-like carbon. The concluding section addresses regulatory considerations and challenges associated with integrating carbon materials into medical devices. This review culminates by providing insights into current achievements, challenges, and future directions, underscoring the pivotal role of carbon nanomaterials and their metal composites in advancing biocompatible applications.

Oligomerization and a distinct tRNA-binding loop are important regulators of human arginyl-transferase function.

The arginyl-transferase ATE1 is a tRNA-dependent enzyme that covalently attaches an arginine molecule to a protein substrate. Conserved from yeast to humans, ATE1 deficiency in mice correlates with defects in cardiovascular development and angiogenesis and results in embryonic lethality, while conditional knockouts exhibit reproductive, developmental, and neurological deficiencies. Despite the recent revelation of the tRNA binding mechanism and the catalytic cycle of yeast ATE1, the structure-function relationship of ATE1 in higher organisms is not well understood. In this study, we present the three-dimensional structure of human ATE1 in an apo-state and in complex with its tRNA cofactor and a peptide substrate. In contrast to its yeast counterpart, human ATE1 forms a symmetric homodimer, which dissociates upon binding of a substrate. Furthermore, human ATE1 includes a unique and extended loop that wraps around tRNAArg, creating extensive contacts with the T-arm of the tRNA cofactor. Substituting key residues identified in the substrate binding site of ATE1 abolishes enzymatic activity and results in the accumulation of ATE1 substrates in cells.
