Rerefinement of the crystal structure of BiF.

The crystal structure of bis-muth penta-fluoride, BiF, was rerefined from single-crystal data. BiF crystallizes in the α-UF structure type in the form of colorless needles. In comparison with the previously reported crystal-structure model [Hebecker (1971 ▸).

Histological and clinical evaluation of discarded kidneys in a European cohort of deceased brain death donor kidneys of marginal quality.

Background: Despite organ shortages, the discard rate of deceased donor kidneys is high. Risk factors for this trend warrant further study.

Methods: We investigated reasons for discard in a cohort of brain death donors with marginal kidneys and procurement biopsies.

Discrete Mono-, Di-, and Trinuclear Anions [MoOF], [MoOF], [MoOF], [MoOF], [MoOF], and the Infinite Chain Anion [MoOF] Obtained from Reactions of MoOF: Synthesis and Analysis of the Structure-Chemical Relations of the Compounds.

The herein-reported oxyfluoridometallate salts were synthesized and structurally characterized during the studies of the Lewis acidity of OF ( = Mo, W) with various fluoride ion donors (RbF, CsF, TlF, AgF, SrF, BaF, PbF) in different solvents (aqHF 48%, aHF, BrF, ClF). Phase-pure MoOF was either synthesized by hydrolysis of MoF with SiO in anhydrous HF (aHF) or by reactions of BrF with MoO or MoO, respectively. The compound was characterized by infrared and Raman spectroscopy, solid-state quantum-chemical calculations, as well as powder and single-crystal X-ray diffraction.

Overcultured? Blood cultures on discharged ED patients were ordered more frequently after the SEP-1 bundle initiation.

Introduction: In 2015, the Severe Sepsis and Early Septic Shock Management Bundle (SEP-1) tied hospital reimbursement to performance on a series of time sensitive indicators, including ordering blood cultures on patients with severe sepsis or septic shock. This metric could have broadly shaped ordering practices in the Emergency Department (ED), including for patients who did not have severe sepsis or septic shock. In this study, we sought to evaluate whether the frequency of blood culture orders on adult patients discharged from the ED changed after the SEP-1 metric, whether the rates of positivity for pathogens or contaminants changed after the SEP-1 metric, and whether similar changes were seen in orders for other laboratory tests.
