ABSTRACT
BACKGROUND: Critically ill neonates receive care in the neonatal intensive care unit (NICU). Unfortunately, some neonates pass away in the NICU. Providing comprehensive neonatal palliative care and hospice services is crucial in supporting parents through the loss of their offspring. In our NICU, we identified that only 74.5% of nurses are able to properly recognize the need for palliative care and only 55% are able to implement the necessary procedures. PURPOSE: A project was designed and implemented to enhance the ability of nursing staff to recognize the need for and properly implement palliative care to improve the quality of this care in the NICU. RESOLUTIONS: We organized an on-the-job education and training program within our NICU with the goals of heightening awareness among nursing staff. In addition, a specialist palliative care operation flow chart, process preparation checklist, and palliative-care-related tools were created to facilitate the care process. RESULTS: After program implementation, among nursing staff in our NICU, the palliative care recognition accuracy rate rose to 100% (from 74.5%) and the implementation rate rose to 94.8% (from 55%). The quality of provided neonatal palliative care and hospice services was significantly improved. CONCLUSIONS: The developed program was shown to significantly improve nursing staff recognition and implementation of neonatal palliative care in our NICU. This experience provides a reference for improving palliative care quality and for helping families effectively manage end-of-life challenges.

The reaction of amidinatosilylene LSi(:)Cl [L = PhC(NtBu)2] with N-heterocyclic carbene IAr [:C{N(Ar)CH}2, where Ar = 2,6-iPr2C6H3] and NaOTf in tetrahydrofuran (THF) facilely afforded a silicon(II) cation [LSi(:)-aIAr]+OTf- (1+OTf-), where IAr isomerizes to abnormal N-heterocyclic carbene aIAr, coordinating to the silicon(II) center. Its Ge homologue, [LGe(:)-aIAr]+OTf- (2+OTf-), was also accessed via the same protocol. For the formation of 1+, we propose that an in situ-generated Si(II) cation [LSi(:)]+ under the treatment of LSi(:)Cl with NaOTf may isomerize IAr in THF. In contrast, the replacement of IAr with cyclic alkyl(amino) carbene (cAAC) furnished a cAAC-silanyl radical ion [LSi(H)-cAAC]â¢+(LiOTf2)- [3â¢+(LiOTf2)-], which may undergo an abstraction of the H radical from THF. All of the products were characterized by nuclear magnetic resonance spectroscopy, electron paramagnetic resonance, and X-ray crystallography, and their bonding scenarios were investigated by density functional theory calculations. These studies provide new perspective on carbene-silicon chemistry.
ABSTRACT
This study describes the first use of a silicon(II) complex, NHC-parent silyliumylidene cation complex [(IMe)2SiH]I (1, IMe = :C{N(Me)C(Me)}2) as a versatile catalyst in organic synthesis. Complex 1 (loading: 10 mol %) was shown to act as an efficient catalyst (reaction time: 0.08 h, yield: 94%, TOF = 113.2 h-1; reaction time: 0.17 h, yield: 98%, TOF = 58.7 h-1) for the selective reduction of CO2 with pinacolborane (HBpin) to form the primarily reduced formoxyborane [pinBOC(âO)H]. The activity is better than the currently available base-metal catalysts used for this reaction. It also catalyzed the chemo- and regioselective hydroboration of carbonyl compounds and pyridine derivatives to form borate esters and N-boryl-1,4-dihydropyridine derivatives with quantitative conversions, respectively. Mechanistic studies show that the silicon(II) center in complex 1 activated the substrates and then mediated the catalytic hydroboration. In addition, complex 1 was slightly converted into the NHC-borylsilyliumylidene complex [(IMe)2SiBpin]I (3) in the catalysis, which was also able to mediate the catalytic hydroboration.
