Common genetic variation in the ABCB1 gene is associated with the cholesterol-lowering effect of simvastatin in males.
Becker ML, Visser LE, van Schaik RH, Hofman A, Uitterlinden AG, Stricker BH
Aims: The cholesterol-lowering drug simvastatin is a substrate for P-glycoprotein (P-gp). P-gp, encoded by ABCB1, is an efflux transporter and genetic variation in ABCB1 is associated with drug levels and response. We examined the Rotterdam Study, which is a population-based cohort study of people aged 55 years and older, to see whether the C1236T, G2677T/A and C3435T polymorphisms and haplotypes in the ABCB1 gene are associated with the total cholesterol and low-density lipoprotein cholesterol-...

Exaggerated risk: prospect theory and probability weighting in risky choice.
Kusev P, van Schaik P, Ayton P, Dent J, Chater N
In 5 experiments, we studied precautionary decisions in which participants decided whether or not to buy insurance with specified cost against an undesirable event with specified probability and cost. We compared the risks taken for precautionary decisions with those taken for equivalent monetary gambles. Fitting these data to Tversky and Kahneman's (1992) prospect theory, we found that the weighting function required to model precautionary decisions differed from that required for monetary...

Transition of Enterococcus faecium from commensal organism to nosocomial pathogen.
Willems RJ, van Schaik W
The Gram-positive species Enterococcus faecium has long been thought of as a harmless commensal of the mammalian GI tract. In the last two decades, however, E. faecium has become an important cause of nosocomial bacteremias. These infections are often difficult to treat owing to the resistance of E. faecium to a large number of antibiotics. In this article, we review the recent transition of E. faecium from commensal to nosocomial pathogen. We focus on population biology-based studies, which sug...

Motion-gated acquisition for in vivo optical imaging.
Gioux S, Ashitate Y, Hutteman M, Frangioni JV
Wide-field continuous wave fluorescence imaging, fluorescence lifetime imaging, frequency domain photon migration, and spatially modulated imaging have the potential to provide quantitative measurements in vivo. However, most of these techniques have not yet been successfully translated to the clinic due to challenging environmental constraints. In many circumstances, cardiac and respiratory motion greatly impair image quality and/or quantitative processing. To address this fundamental problem,...

Timing of noncardiac surgery after coronary artery stenting with bare metal or drug-eluting stents.
van Kuijk JP, Flu WJ, Schouten O, Hoeks SE, Schenkeveld L, de Jaegere PP, Bax JJ, van Domburg RT, Serruys PW, Poldermans D
The current guidelines have recommended postponing noncardiac surgery (NCS) for > or =6 weeks after bare metal stent (BMS) placement and for > or =1 year after drug-eluting stent (DES) placement. However, much debate has ensued about these intervals. The aim of the present study was to assess the influence of different intervals between stenting and NCS and the use of dual antiplatelet therapy on the occurrence of perioperative major adverse cardiac events (MACEs). We identified 550 patien...

Why, how and when do we need to optimize the setting of cardiac resynchronization therapy?
Bertini M, Delgado V, Bax JJ, Van de Veire NR
Current cardiac resynchronization therapy (CRT) devices allow manipulation of the atrioventricular (AV) and interventricular (VV) timings in order to maximize the left ventricular (LV) performance. Multiple echocardiographic and non-echocardiographic methods have been proposed to optimize AV and VV intervals but no consensus has been reached on which methodology should preferably be used. Furthermore, different physiologic conditions, such as rest and exercise, may markedly change LV loading con...
