A proficient multivariate approach for iron(II) spin crossover behaviour modelling in the solid state.

Iron(II) -pyrazolilpyridyl (bpp-R) complexes [Fe(bpp-R)](X)·solvent, R = substituent and X = anion, can undergo a spin transition from high ( = 2, HS) to low spin ( = 0, LS), being spin crossover (SCO) in the solid state. The distortion of the octahedral coordination environment around the metal centre is governed by crystal packing, the intermolecular interactions among the substituent R of the bpp-R ligands, the anion X, and the co-crystallized solvent, and this modulates the SCO behaviour. In this work, an innovative multivariate approach, through the combination of the chemometric tools Principal Component Analysis and Partial Least Squares regression, was applied on the coordination bond distances and angles and selected torsional angles of the available HS structures.

Using the Theory of Planned Behavior to explore hospital-based nurses' intention to use peripherally inserted central catheter (PICC): a survey study.

Background And Aim Of The Work: The peripherally inserted central catheters (PICC) have become an alternative to the traditional CVC. PICCs are usually inserted by trained nurses who decided to attend and complete a special training on PICC insertion and management. The present work aimed to investigate the intention of using PICC in a sample of hospital-based nurses using the theory of planned behavior as theoretical framework.

[Hepatic abscess: series of 107 cases and literature review].

Unlabelled: Liver abscess is a rare disease with high morbidity and mortality.

Objective And Method: Description of liver abscess cases attended in the Universidad de Chile Clinical Hospital between 2000 and 2007 and review of the literature on the topic.

Results: For 107 cases reviewed, mean age was 59 years.

Hemodialysis-associated cardiac arrhythmias: a lower risk with bicarbonate?

The role of hemodialysis (HD) as an arrhythmogenic event has recently been emphasized. We studied 18 patients by Holter monitoring, comparing the arrhythmogenic effect of acetate dialysis (AHD) and bicarbonate dialysis (BHD). The frequency of ventricular arrhythmias was 93 +/- 66/h in AHD and 32 +/- 26/h in BHD (p less than 0.
