The American journal of cardiology, Volume 89, Issue 8, 1 1 2002, Pages 964-968 Prediction of mortality in heart transplant recipients by stress technetium-99m tetrofosmin myocardial perfusion imaging. Elhendy A, van Domburg RT, Vantrimpont P, Poldermans D, Bax JJ, van Gelder T, Baan CC, Schinkel A, Roelandt JR, Balk AH

Cardiac allograft vasculopathy is a major cause of mortality in heart transplant recipients. The aim of this study was to assess the prognostic value of stress myocardial perfusion imaging in heart transplant recipients. We studied 166 patients (age 54 +/- 10 years, 140 men) by symptom-limited bicycle exercise or dobutamine (up to 40 microg/kg/min) stress myocardial perfusion imaging 7.4 +/- 2.5 years after heart transplantation. An intravenous dose of 370 MBq of technetium-99m tetrofosmin was i... Abstract

Radiology, Volume 223, Issue 1, 1 1 2002, Pages 204-211 Exercise MR imaging in the assessment of pulmonary regurgitation and biventricular function in patients after tetralogy of fallot repair. Roest AA, Helbing WA, Kunz P, van den Aardweg JG, Lamb HJ, Vliegen HW, van der Wall EE, de Roos A

Purpose: To assess the responses of pulmonary regurgitation (PR) and biventricular function to submaximal exercise by using a magnetic resonance (MR) imaging exercise protocol with young adult patients who underwent tetralogy of Fallot repair at a young age. Materials and methods: Fifteen patients with corrected tetralogy of Fallot (mean age, 17.5 years +/- 2.5 [SD]) underwent MR imaging at rest and during exercise for the evaluation of PR and biventricular function. Results were compared with f... Abstract

American journal of physiology. Heart and circulatory physiology, Volume 282, Issue 4, 1 1 2002, Pages H1350-8 Indexes of diastolic RV function: load dependence and changes after chronic RV pressure overload in lambs. Leeuwenburgh BP, Steendijk P, Helbing WA, Baan J

Diastolic function is a major determinant of ventricular performance, especially when loading conditions are altered. We evaluated biventricular diastolic function in lambs and studied possible load dependence of diastolic parameters [minimum first derivative of pressure vs. time (dP/dt(min)) and time constant of isovolumic relaxation (tau)] in normal (n = 5) and chronic right ventricular (RV) pressure-overloaded (n = 5) hearts by using an adjustable band on the pulmonary artery (PAB). Pressure-... Abstract

Nederlands tijdschrift voor geneeskunde, Volume 146, Issue 10, 1 1 2002, Pages 473-477 [Surgery and referral for subsequent 131I therapy for patients with differentiated thyroid carcinoma in the south-east of the Netherlands, 1983-1996, compared to the consensus guidelines from 1987]. Kuijpens JL, Hoekstra OS, Hamming JF, Haak HR, Ribot JG, Coebergh JW

Objective: To evaluate the treatment of patients with differentiated (papillary or follicular) thyroid cancer in general hospitals in the south-east of the Netherlands during the period 1983-1996, in relation to the 1987 national consensus recommendations. Design: Population-based, retrospective, descriptive.

British journal of cancer, Volume 86, Issue 5, 1 1 2002, Pages 811-818 A fully human anti-Ep-CAM scFv-beta-glucuronidase fusion protein for selective chemotherapy with a glucuronide prodrug. de Graaf M, Boven E, Oosterhoff D, van der Meulen-Muileman IH, Huls GA, Gerritsen WR, Haisma HJ, Pinedo HM

Monoclonal antibodies against tumour-associated antigens could be useful to deliver enzymes selectively to the site of a tumour for activation of a non-toxic prodrug. A completely human fusion protein may be advantageous for repeated administration, as host immune responses may be avoided. We have constructed a fusion protein consisting of a human single chain Fv antibody, C28, against the epithelial cell adhesion molecule and the human enzyme beta-glucuronidase. The sequences encoding C28 and h... Abstract

European journal of nuclear medicine and molecular imaging, Volume 29, Issue 4, 19 3 2002, Pages 452-457 Feasibility, safety and image quality of cardiac FDG studies during hyperinsulinaemic-euglycaemic clamping. Bax JJ, Visser FC, Poldermans D, van Lingen A, Elhendy A, Boersma E, Visser CA

Fluorine-18 fluorodeoxyglucose (FDG) imaging for the assessment of myocardial viability has become an integral part of the diagnostic and prognostic work-up of patients with ischaemic cardiomyopathy. To ensure good image quality, in particular in patients with diabetes mellitus, hyperinsulinaemic-euglycaemic clamping has been proposed. In this study we evaluated the safety and the image quality of cardiac FDG imaging during clamping in a large group of patients, including a subgroup with diabete... Abstract

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 10, Issue 2, 1 1 2002, Pages 43-47 Rhythmic sensory stimulation improves fitness by conditioning the autonomic nervous system. Frederiks J, Swenne CA, Ghafoerkhan A, Lalmahomed H, Maan AC, Schalij MJ, Bruschke AV, van der Wall EE

Background: Endurance training is known to alter the functioning of the autonomic nervous system, a major goal when pursuing fitness. Here, we test the hypothesis that the training-associated rhythmic sensations alone, hence without the usual accompanying physical exercise, accomplish this effect. Method: We studied sixteen resting healthy male volunteers, age (mean±SD) 25.9±3.7 years. During one hour we applied, at marching pace (2 bursts per second), bipolar transcutaneous electrical sensory n... Abstract

British journal of cancer, Volume 86, Issue 3, 1 1 2002, Pages 436-442 Prerequisites for effective adenovirus mediated gene therapy of colorectal liver metastases in the rat using an intracellular neutralizing antibody fragment to p21-Ras. van Etten B, ten Hagen TL, de Vries MR, Ambagtsheer G, Huet T, Eggermont AM

Ras mutations are present in 40-50% of colorectal cancers. Inactivating this oncogene may therefore reduce proliferation capacity. In order to target ras we studied the transduction efficacy and anti tumour activity of an adenoviral vector expressing an intracellular, neutralizing single chain antibody to p21-ras (Y28). In in vitro studies transfection levels of the K-ras mutated rat colon carcinoma cell line CC531 were studied using the LacZ marker gene. In our in vivo liver metastases model di... Abstract

Background: Patients with Brugada syndrome present with characteristic ECG abnormalities (atypical right bundle-branch block and ST-segment elevation) and life-threatening ventricular tachyarrhythmias despite structurally normal hearts. Involvement of the autonomic nervous system is suggested by the occurrence of ventricular tachyarrhythmias and sudden death at rest or during sleep and by changes of typical ECG signs under pharmacological modulation of the myocardial autonomic tone. Methods and... Abstract

Clinical genetics, Volume 61, Issue 2, 1 1 2002, Pages 115-125 ABCA1 regulatory variants influence coronary artery disease independent of effects on plasma lipid levels. Zwarts KY, Clee SM, Zwinderman AH, Engert JC, Singaraja R, Loubser O, James E, Roomp K, Hudson TJ, Jukema JW, Kastelein JJ, Hayden MR

The authors have previously shown that individuals heterozygous for ABCA1 mutations have decreased high density lipoprotein cholesterol, increased triglycerides and an increased frequency of coronary artery disease (CAD), and that single nucleotide polymorphisms (SNPs) in the coding region of the ABCA1 gene significantly impact plasma lipid levels and the severity of CAD in the general population. They have now identified several SNPs in non-coding regions of ABCA1 which may be important for the... Abstract

A 75-year-old man complaining of acute abdominal pain, 1 month after elective surgical repair of an abdominal aortic aneurysm by an aortabi-iliac bypass graft, was referred and admitted to the emergency room. Imaging by sonography and computed tomography scan revealed a ruptured iliac pseudoaneurysm at the right iliac anastomotic site with associated large retroperitoneal hematoma. We inserted a self-expanding covered Z-stent graft by a transfemoral approach and the iliac anastomotic pseudoaneur... Abstract

Background: The application of previous magnetic resonance (MR) angiography techniques has enabled noninvasive differentiation between patent and occluded coronary artery bypass grafts. However, the detection of graft stenosis remains difficult. The purpose of our study was to determine the accuracy of high-resolution navigator-gated 3-dimensional (3-D) MR angiography in detecting vein graft disease. Methods and Results- MR angiography was performed in addition to coronary angiography with quant... Abstract
