The vulnerable artery: early and rapid deposition of lipid in coronary arteries is associated with subsequent development of thin-cap fibroatheromas.

Aims: We aimed to determine whether intravascular ultrasound (IVUS) and near infrared spectroscopy (NIRS) could identify arteries which would subsequently develop a thin-cap fibroatheroma (TCFA).

Methods And Results: Three-vessel angiography, IVUS and NIRS evaluations were performed at three, six and nine months after induction of diabetes mellitus and hypercholesterolaemia in 13 Yorkshire pigs (n=37 arteries). In vivo total arterial plaque plus media (P+M) area, echo-attenuated plaque (AP) area by IVUS, and lipid core burden index (LCBI) by NIRS were compared to histology at nine months.

Subsequent development of fibroatheromas with inflamed fibrous caps can be predicted by intracoronary near infrared spectroscopy.

Objective: To prospectively evaluate whether the development of fibroatheromas exhibiting features of potential instability can be detected and predicted by serial invasive imaging.

Methods And Results: Multivessel intravascular ultrasound and near infrared spectroscopy (NIRS) were performed in diabetic/hypercholesterolemic pigs 3, 6, and 9 months after induction. Animals were euthanized at 9 months and histological/immunohistochemical evaluation of the arteries was performed (n=304 arterial segments).

Smoking prevention and cessation programme in cystic fibrosis: integrating an environmental health approach.

Background: There have been several studies assessing the epidemiology and effects of tobacco smoke in the cystic fibrosis (CF) population, but few address the efforts of smoking cessation interventions. Our objective is to present one tobacco prevention and cessation programme targeting patients with CF in the Mediterranean region of Murcia (Spain).

Methods: All registered patients in the Regional CF unit (n=105) in 2008 were included in a cross-sectional and prospective uncontrolled study of tobacco use and exposure in CF patients using a baseline and 1-year follow-up.

Vascular responses to drug-eluting and bare metal stents in diabetic/hypercholesterolemic and nonatherosclerotic porcine coronary arteries.

Background: Animal models used to gain insight into the vascular response to drug-eluting stents are generally juvenile and nonatherosclerotic, whereas stents are placed in patients with complex atherosclerosis and comorbidities. Hence, models reflecting these complexities are needed to help elucidate the vascular effects of drug-eluting stents. We compared the vascular responses with bare metal stent (BMS) and paclitaxel-eluting stent (PES) implantation in a diabetic/hypercholesterolemic (DM/HC) porcine model of advanced coronary atherosclerosis with the standard juvenile porcine model.

Re-invigorating Japan's commitment to global health: challenges and opportunities.

Over the past 50 years, Japan has successfully developed and maintained an increasingly equitable system of universal health coverage in addition to achieving the world's highest life expectancy and one of the lowest infant mortality rates. Against this backdrop, Japan is potentially in a position to become a leading advocate for and supporter of global health. Nevertheless, Japan's engagement with global health has not been outstanding relative to its substantial potential, in part because of government fragmentation, a weak civil society, and lack of transparency and assessment.
