Bifurcation lesions involved in the recanalization process of coronary chronic total occlusions: Incidence, treatment and clinical implications.

Background: The presence of a bifurcation (BL) in the context of a coronary chronic total occlusion (CTO) represents an additional difficulty. This study analyzes the incidence of BLs in CTO recanalization, the treatment, predictors of bifurcation technical success and their clinical impact.

Methods And Results: BLs with a side branch (SB) ≥2.

Effect of early treatment with ivabradine combined with beta-blockers versus beta-blockers alone in patients hospitalised with heart failure and reduced left ventricular ejection fraction (ETHIC-AHF): A randomised study.

Objectives: To analyse the effect of the early coadministration of ivabradine and beta-blockers (intervention group) versus beta-blockers alone (control group) in patients hospitalised with heart failure and reduced left ventricular ejection fraction (HFrEF).

Methods: A comparative, randomised study was performed to compare the treatment strategies of beta-blockers alone versus ivabradine and beta-blockers starting 24hours after hospital admission, for acute HF in patients with an left ventricular ejection fraction (EF)<40%, sinus rhythm, and a heart rate (HR)>70bpm.

Results: A total of 71 patients were examined, 33 in the intervention group and 38 in the control group.

Development of a stir bar sorptive extraction method coupled to gas chromatography-mass spectrometry for the analysis of volatile compounds in Sherry brandy.

Sherry brandy (Jerez, SW, Spain) is a high quality distilled beverage derived from wine. Its perceived quality depends, inter alia, on hundreds of flavour compounds. A Stir Bar Sorptive Extraction (SBSE) method coupled to gas chromatography-mass spectrometry has been developed for the analysis of volatile compounds in Sherry brandy.

Traceability of phytosanitary products in the production of a Sherry wine vinegar.

In the present work, the monitoring of the evolution of the different phytosanitary products employed in the production of a Sherry wine vinegar has been carried out. The study covers the complete process, from the grape ripening to the vinegar fermentation. For the liquid sample analysis, a method based on SBSE (stir bar sorptive extraction) coupled to GC-MS and previously developed was used.
