“This Talazoparib concentration contribution reports the study of metastable spin states in spin-crossover materials
in the framework of the atom-phonon coupling model. Using this model for a linear chain we show theoretically for the first time that, even if the cooperativity is not strong enough to obtain hysteresis at high temperatures, metastable states exist at low temperatures for a high spin (HS) fraction of n(HS) = 1. This gradual thermal transition featuring metastable states at low temperature has been observed experimentally by [Letard et al., J. Phys.: Conf. Ser. 21, 23 (2005)]. Moreover, for compounds showing a two-step thermal transition, we show that metastable states, corresponding to a HS fraction n(HS) = 0.5, are present. This metastable states appear up to 50 K, fact that was observed by [Moussa et al., Phys. Rev. Lett. 94, 107205 (2005)] and [Matsumoto et al., J. Phys.: Conf. Ser. 148, 012029 (2009)].

“BackgroundHypothermia (core body temperature <36 degrees C) during surgery has been associated with surgical site infection,
a major risk in all spine deformity surgeries. Forced air warming is an important method of intraoperative temperature maintenance in children. In mid-2010, we empirically introduced preoperative warming as a strategy to reduce intraoperative hypothermia.
ObjectiveWe report the prevalence and extent of hypothermia during spine deformity surgeries at our institution
and evaluate the effect of the BLZ945 introduction of preoperative warming.
MethodsWe performed a retrospective audit of temperature data in children who underwent spine deformity surgeries during two-seven-month periods: November 2011 to June 2012 and 2years prior to this period (before preoperative warming implementation). Specifically, the following data were obtained: (i) case duration; (ii) first measured temperature; (iii) last measured temperature; (iv) percentage of case spent hypothermic; (v) number of Galardin inhibitor hypothermic episodes per case, and (vi) delay between case start and time of first temperature measured. Data were compared visually and using the Mann-Whitney U-test. Confidence intervals (CI) were obtained using the Hodges-Lehmann estimator.
ResultsPreoperative warming reduced the percentage of case duration spent hypothermic by a median of 111.1min (P<0.001, 95% CI 77.1-139.9min). Additionally, it increased the first measured temperature by a median of 0.5 degrees C (P<0.001, 95% CI 0.3-0.7 degrees C). The last temperature at the end of the case remained unchanged (P=0.57, 95% CI -0.2-0.1 degrees C).
ConclusionPreoperative warming of children undergoing spine deformity surgery significantly reduces the percentage of case spent hypothermic, thereby potentially reducing risk of perioperative complications.
