Journal of cardiovascular computed tomography, Volume 2, Issue 6, 10 2 2008, Pages 360-365 How do you quantify noncalcified plaque? Schuijf JD, Bax JJ
The ability of multislice computed tomography (MSCT) to visualize not only lumen but also coronary plaques is recognized as an attractive advantage of MSCT over conventional coronary angiography. In particular, the fact that during the administration of contrast not only calcified plaques but also noncalcified plaques can be identified has received enormous interest. Retrospective studies have shown an association between plaques containing noncalcified components and presentation with acute cor... Abstract

Thorax, Volume 64, Issue 1, 3 1 2008, Pages 26-32 Enhanced pulmonary leptin expression in patients with severe COPD and asymptomatic smokers. Vernooy JH, Drummen NE, van Suylen RJ, Cloots RH, Möller GM, Bracke KR, Zuyderduyn S, Dentener MA, Brusselle GG, Hiemstra PS, Wouters EF
Background: Chronic obstructive pulmonary disease (COPD) is characterised by an abnormal inflammatory reaction of the lungs involving activation of epithelial cells. Leptin is a pleiotropic cytokine important in the regulation of immune responses via its functional receptor Ob-Rb. This study was undertaken to test the hypothesis that severe COPD is associated with increased leptin expression in epithelial cells. Methods: Immunohistochemistry for leptin was performed on peripheral lung specimens... Abstract

World journal of surgery, Volume 32, Issue 10, 1 1 2008, Pages 2172-2177 Surgical training in the Netherlands. Borel-Rinkes IH, Gouma DJ, Hamming JF
Surgical training in the Netherlands has traditionally been characterized by learning on the job under the classic master-trainee doctrine. Over the past decades, it has become regionally organized with intensive structural training courses, and a peer-based quality control system. Recently, the nationwide programme has been modernized further and now involves a systematic, competency-based education with structural training courses, formalized assessment and room for reflection by residents und...

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 16, Issue Suppl 1, 1 1 2008, Pages S36-40 Imaging in cardiac resynchronisation therapy. Ypenburg C, van der Wall EE, Schalij MJ, Bax JJ
A substantial number of heart failure (HF) patients do not respond after cardiac resynchronisation therapy (CRT). Recent studies observed that assessment of intraventricular (LV) dyssynchrony may allow identification of potential responders to CRT. In addition, presence of scar tissue and venous anatomy may play a role in the selection of candidates. In this review, an extensive overview of the available LV dyssynchrony measurements is provided using different echocardiographic modalities. In ad... Abstract

Background: : The 6-min walk distance (6MWD) predicts survival in pulmonary hypertension (PH). The peak oxygen consumption (V O2peak) measured during a cardiopulmonary exercise test (CPET) also relates to survival in PH, and it is unknown how the prognostic information from measurements of ventilatory responses and gas exchange during CPET compares to the prognostic information obtained by the 6MWD alone. The aims of our study were to compare prognostic values of different exercise parameters in... Abstract

Acta anaesthesiologica Scandinavica, Volume 52, Issue 9, 1 1 2008, Pages 1194-1203 Establishment of a porcine right ventricular infarction model for cardioprotective actions of xenon and isoflurane. Hein M, Roehl AB, Baumert JH, Bantes B, Bleilevens C, Bernstein N, Steendijk P, Rossaint R
Background: Right ventricular (RV) function is an important determinant of post-operative outcome. Consequences of RV infarction might be limited by pre-conditioning with volatile anesthetic drugs. Therefore, we used a porcine model of RV ischemia and reperfusion (IR) injury to study the influence of isoflurane and xenon on the extent and degree of myocardial injury. Methods: IR injury was induced by a 90-min ligation of the distal right coronary artery and 120-min reperfusion in thiopental anes... Abstract

Respiratory research, Volume 9, 1 1 2008, Pages 68 Membrane diffusion- and capillary blood volume measurements are not useful as screening tools for pulmonary arterial hypertension in systemic sclerosis: a case control study. Overbeek MJ, Groepenhoff H, Voskuyl AE, Smit EF, Peeters JW, Vonk-Noordegraaf A, Spreeuwenberg MD, Dijkmans BC, Boonstra A
Background: There is no optimal screening tool for the assessment of pulmonary arterial hypertension (PAH) in patients with systemic sclerosis (SSc). A decreasing transfer factor of the lung for CO (TLCO) is associated with the development of PAH in SSc. TLCO can be partitioned into the diffusion of the alveolar capillary membrane (Dm) and the capillary blood volume (Vc). The use of the partitioned diffusion to detect PAH in SSc is not well established yet. This study evaluates whether Dm and Vc... Abstract

Journal of electrocardiology, Volume 41, Issue 6, 25 4 2008, Pages 648-655 Normal limits of the spatial QRS-T angle and ventricular gradient in 12-lead electrocardiograms of young adults: dependence on sex and heart rate. Scherptong RW, Henkens IR, Man SC, Le Cessie S, Vliegen HW, Draisma HH, Maan AC, Schalij MJ, Swenne CA
Background and purpose: Normal limits of the spatial QRS-T angle and spatial ventricular gradient (SVG) are only available from Frank vectorcardiograms (VCGs) of male subjects. We determined normal limits for these variables derived from standard 12-lead electrocardiograms (ECGs) of 660 male and female students aged 18 to 29 years. Methods: A computer algorithm was used that constructed approximated VCG leads by inverse Dower matrix transformation of the 12-lead ECG and subsequently calculated t... Abstract

Stem cells (Dayton, Ohio), Volume 26, Issue 12, 18 3 2008, Pages 3210-3217 Phenotypic and functional reversal within the early human hematopoietic compartment. Knaän-Shanzer S, van der Velde-van Dijke I, van de Watering MJ, de Leeuw PJ, Valerio D, van Bekkum DW, de Vries AA
The fate of phenotypically defined human hematopoietic stem cells (hHSCs) in culture and the link between their surface marker expression profile and function are still controversial. We studied these aspects of hHSC biology by relating the expression of the early lineage markers (ELM) CD33, CD38, and CD71 on the surface of human umbilical cord blood (UCB) CD34(+) cells to their long-term nonobese diabetic/severe combined immunodeficient (NOD/SCID) mouse repopulation activity (LT-SRA). In uncult... Abstract

Journal of applied physiology (Bethesda, Md. : 1985), Volume 105, Issue 6, 18 3 2008, Pages 1725-1732 Enhanced airway dilation by positive-pressure inflation of the lungs compared with active deep inspiration in patients with asthma. Slats AM, Janssen K, de Jeu RC, van der Plas DT, Schot R, van den Aardweg JG, Sterk PJ
Deep inspiration temporarily reduces induced airways obstruction in healthy subjects. This bronchodilatory effect of deep inspiration is impaired in asthma. Passive machine-assisted lung inflation may augment bronchodilation compared with an active deep inspiration in patients with asthma by either opening closed airways or by reducing fluid flux across the airway wall during deep inspiration, and thereby increasing the tethering forces on the airway wall. We recruited 24 patients with asthma [1... Abstract

The American journal of cardiology, Volume 102, Issue 10, 6 1 2008, Pages 1366-1372 Comparison between tissue Doppler imaging and velocity-encoded magnetic resonance imaging for measurement of myocardial velocities, assessment of left ventricular dyssynchrony, and estimation of left ventricular filling pressures in patients with ischemic cardiomyopathy. Marsan NA, Westenberg JJ, Tops LF, Ypenburg C, Holman ER, Reiber JH, de Roos A, van der Wall EE, Schalij MJ, Roelandt JR, Bax JJ
Velocity-encoded magnetic resonance imaging (VE-MRI), commonly used to perform flow measurements, can be applied for myocardial velocity analysis, similar to tissue Doppler imaging (TDI). In this study, a comparison between VE-MRI and TDI was performed for the assessment of left ventricular dyssynchrony and left ventricular filling pressures. Ten healthy volunteers and 22 patients with heart failure secondary to ischemic cardiomyopathy underwent both VE-MRI and TDI. Longitudinal myocardial peak... Abstract
