Purpose: This study aimed to clarify the concept of pediatric hospice and palliative care through conceptual analysis. It also sought to identify the differences between related concepts such as pediatric death care and pediatric spiritual care, in order to provide foundational data for the development of nursing theory and knowledge. Methods: A conceptual analysis of pediatric hospice and palliative care was conducted using Rodgers’ evolutionary method. Out of 5,013 papers identified, 28 were selected for detailed reading and analysis. Results: Pediatric hospice and palliative care encompasses physical, psychological, social, mental, spiritual, and family care for children with acute and chronic diseases with uncertain prognoses ahead of death, as well as their families. Effective pediatric hospice and palliative care will require multidisciplinary team nursing, effective communication, and supportive policies. Conclusion: The findings of this study suggest that providing pediatric hospice and palliative care will lead to improvements in pain relief for children and families, the efficiency of responses to death in children, and the quality of life for children and families. The significance of this study is that it clearly clarifies the concept by analyzing pediatric hospice and palliative care using an evolutionary method. [ABSTRACT FROM AUTHOR]

In this tandem reaction the carbon-carbon triple bond of an alkyne is catalytically cleaved in association with aldehyde, al?kene, and H 2O under catalyst mixtures of Rh(I), 2-amino-3-picoline, primary amine, and acid. The reaction starts with chelation-assisted hydroacylation of the alkyne with an aldehyde. The retro-Mannich-type fragmentation of the resulting ?,?-unsaturated ketimine by an amine and acid affords a ketimine and an aldimine, which is trapped by an alkene and give ketones after hydrolysis.
