Combination Tools for Calcium Modification from RASER to Orbitalshock.

Coronary artery calcification is frequently encountered during percutaneous coronary intervention and its presence is associated with a higher risk of stent under-expansion which has been associated with long-term risk of stent failure. There are several different calcium modification strategies available, whether they be balloon-based devices (cutting/scoring and intravascular lithotripsy) or atherectomy devices (orbital atherectomy, rotational atherectomy, excimer laser coronary atherectomy) that are established for the modification of coronary calcification. Each strategy applies a different mechanism of action for calcium modulation and consequently the potential to combine modifying tools may offer synergistic advantages over device monotherapy.

Towards the identification of transmission pathways and early detection of Enterococcus cecorum infection in broiler chickens.

Enterococcus cecorum (EC) infection is an emerging endemic disease in UK and global broiler poultry with major economic impact and welfare concerns. There are significant research gaps with regards to EC pathogenesis, source of infection, transmission routes and early detection of disease, which this study aimed to address. In this prospective study, 725 environmental samples were collected from 4 broiler farms (A-D) the day before chick placement (d 1) and through the subsequent crop (d 7, 14, and 21).

The relationship between ambulatory arterial stiffness index and incident atrial fibrillation.

Background: The ambulatory arterial stiffness index (AASI) is an indirect measure of blood pressure variability and arterial stiffness which are atrial fibrillation (AF) risk factors. The relationship between AASI and AF development has not been previously investigated and was the primary aim of this study.

Methods: This was an observational cohort study of adults (aged 18-85 years) in sinus rhythm, who underwent 24-h ambulatory blood pressure monitoring (ABPM) for the diagnosis of hypertension or its control.

An analysis of long-term clinical outcome following the use of excimer laser coronary atherectomy in a large UK PCI center.

Background: Excimer laser atherectomy (ELCA) is an established adjunctive technique to facilitate acute success in percutaneous coronary intervention (PCI). Despite this there are a lack of contemporary outcome data, particulary longer-term, forpatients treated with ELCA PCI.

Aims: To evaluate the contemporary use ofELCA in PCI, the frequency of periprocedural complications and the longer-term outcomes associated with ELCA PCI.
