Decreasing Unnecessary Pharmacy Cost in the Cath Lab
AngioMax is a single dose heparin alternative introduced in 2002 that is used in cardiac patients undergoing percutaneous intervention (PCI). Bivalirudin costs 15 per dose. Noting practice variations, the Cath Lab set out to eliminate unnecessary pharmacy cost for PCI patients by: Using current literature to inform clinical care Standardizing practice Using data to track and guide implementationhttps://digitalcommons.centracare.com/nursing_posters/1097/thumbnail.jp
Decreasing Polypharmacy in a Long-Term Care Setting with the Use of the STOPP Tool
Polypharmacy is the use of five or more medications. Polypharmacy in older adults can increase fall risk, decrease quality of life, increase adverse reactions and cause a more rapid decline in cognitive function. A literature review revealed that there is benefit to a reduced number of medications taken in the older adult population. This quality improvement project was completed at a long-term care facility in Central Minnesota. The STOPP tool was implemented with the leadership team at the facility which included the Director of Nursing, nursing manager, the PIPP Grant team and the staff development nurse. The project provided education on the use of the Screening Tool of Older Peopleâs Prescriptions (STOPP) with the goal of lowering the overall number of medications that were prescribed to residents in the facility. This screening tool assisted staff in determining unnecessary medications prescribed and aided in conversations with nursing staff and providers to help them determine which medications could be discontinued. The STOPP tool will be used by the leadership staff upon new resident admission to help determine the presence of unnecessary medications that will be reviewed by the provider to be considered for discontinuation
Two-electron reductive carbonylation of terminal uranium(V) and uranium(VI) nitrides to cyanate by carbon monoxide
Two-electron reductive carbonylation of the uranium(VI) nitride [U(TrenTIPS)(N)] (2, TrenTIPS=N(CH2CH2NSiiPr3)3) with CO gave the uranium(IV) cyanate [U(TrenTIPS)(NCO)] (3). KC8 reduction of 3 resulted in cyanate dissociation to give [U(TrenTIPS)] (4) and KNCO, or cyanate retention in [U(TrenTIPS)(NCO)][K(B15C5)2] (5, B15C5=benzo-15-crown-5 ether) with B15C5. Complexes 5 and 4 and KNCO were also prepared from CO and the uranium(V) nitride [{U(TrenTIPS)(N)K}2] (6), with or without B15C5, respectively. Complex 5 can be prepared directly from CO and [U(TrenTIPS)(N)][K(B15C5)2] (7). Notably, 7 reacts with CO much faster than 2. This unprecedented f-block reactivity was modeled theoretically, revealing nucleophilic attack of the Ï* orbital of CO by the nitride with activation energy barriers of 24.7 and 11.3â
kcalâmolâ1 for uranium(VI) and uranium(V), respectively. A remarkably simple two-step, two-electron cycle for the conversion of azide to nitride to cyanate using 4, NaN3 and CO is presented

Terminal uranium(V/VI) nitride activation of carbon dioxide and carbon disulfide: factors governing diverse and well-defined cleavage and redox reactions
The reactivity of terminal uranium(V/VI) nitrides with CE2 (E=O, S) is presented. Well-defined C=E cleavage followed by zero-, one-, and two-electron redox events is observed. The uranium(V) nitride [U(TrenTIPS)(N)][K(B15C5)2] (1, TrenTIPS=N(CH2CH2NSiiPr3)3; B15C5=benzo-15-crown-5) reacts with CO2 to give [U(TrenTIPS)(O)(NCO)][K(B15C5)2] (3), whereas the uranium(VI) nitride [U(TrenTIPS)(N)] (2) reacts with CO2 to give isolable [U(TrenTIPS)(O)(NCO)] (4); complex 4 rapidly decomposes to known [U(TrenTIPS)(O)] (5) with concomitant formation of N2 and CO proposed, with the latter trapped as a vanadocene adduct. In contrast, 1 reacts with CS2 to give [U(TrenTIPS)(Îș2-CS3)][K(B15C5)2] (6), 2, and [K(B15C5)2][NCS] (7), whereas 2 reacts with CS2 to give [U(TrenTIPS)(NCS)] (8) and âSâ, with the latter trapped as Ph3PS. Calculated reaction profiles reveal outer-sphere reactivity for uranium(V) but inner-sphere mechanisms for uranium(VI); despite the wide divergence of products the initial activation of CE2 follows mechanistically related pathways, providing insight into the factors of uranium oxidation state, chalcogen, and NCE groups that govern the subsequent divergent redox reactions that include common one-electron reactions and a less-common two-electron redox event. Caution, we suggest, is warranted when utilising CS2 as a reactivity surrogate for CO2

Oxidation of Alcohols and Activated Alkanes with Lewis Acid-Activated TEMPO
The reactivity of MCl3(η(1)-TEMPO) (M = Fe, 1; Al, 2; TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) with a variety of alcohols, including 3,4-dimethoxybenzyl alcohol, 1-phenyl-2-phenoxyethanol, and 1,2-diphenyl-2-methoxyethanol, was investigated using NMR spectroscopy and mass spectrometry. Complex 1 was effective in cleanly converting these substrates to the corresponding aldehyde or ketone. Complex 2 was also able to oxidize these substrates; however, in a few instances the products of overoxidation were also observed. Oxidation of activated alkanes, such as xanthene, by 1 or 2 suggests that the reactions proceed via an initial 1-electron concerted proton-electron transfer (CPET) event. Finally, reaction of TEMPO with FeBr3 in Et2O results in the formation of a mixture of FeBr3(η(1)-TEMPOH) (23) and [FeBr2(η(1)-TEMPOH)]2(Ό-O) (24), via oxidation of the solvent, Et2O
