Relation of resting heart rate to prognosis in patients with idiopathic pulmonary arterial hypertension.
Henkens IR, Van Wolferen SA, Gan CT, Boonstra A, Swenne CA, Twisk JW, Kamp O, van der Wall EE, Schalij MJ, Vonk-Noordegraaf A, Vliegen HW
Heart rate (HR) at rest is an important marker of prognosis in heart failure, but has not been addressed in pulmonary arterial hypertension (PAH). To determine the prognostic value of HR at rest in patients with PAH, we retrospectively analyzed 140 consecutive patients with idiopathic PAH. Electrocardiogram (ECG)-derived HR at rest was evaluated as a potential predictor of adverse prognosis (death or lung transplantation), in addition to World Health Organization functional class, 6-minute walk...

Association between the CYP2D6*4 polymorphism and depression or anxiety in the elderly.
Bijl MJ, Luijendijk HJ, van den Berg JF, Visser LE, van Schaik RH, Hofman A, Vulto AG, van Gelder T, Tiemeier H, Stricker BH
Introduction: 5-methoxytryptamine (5-MT), a precursor of serotonin, is considered to be an endogenous substrate of cytochrome P450 2D6 (CYP2D6). Homozygous carriers of the variant allele CYP2D6*4 lack CYP2D6 enzyme activity. Relative to extensive metabolizers, these poor metabolizers may have lower baseline serotonin concentrations in various brain regions, and may be more prone to depression or anxiety. Aim: To test whether the CYP2D6*4/*4 genotype is associated with a predisposition to depress...

A psychophysical evaluation of near-field head-related transfer functions synthesized using a distance variation function.
Kan A, Jin C, van Schaik A
A method for synthesizing near-field head-related transfer functions (HRTFs) from far-field HRTFs measured using an acoustic point-source of sound is presented. Near-field HRTFs are synthesized by applying an analytic function describing the change in the transfer function when the location of a sound source changes from the far-field to the near-field: the distance variation function (DVF). The DVF is calculated from a rigid sphere model and approximates the change in the frequency-dependent in...

No increased risk of valvular heart disease in adult poststreptococcal reactive arthritis.
van Bemmel JM, Delgado V, Holman ER, Allaart CF, Huizinga TW, Bax JJ, van der Helm-van Mil AH
Objective: Poststreptococcal reactive arthritis (ReA) is a (poly)arthritis presenting after a Streptococcus group A infection. Acute rheumatic fever (ARF), albeit caused by the same pathogen, has different risk characteristics and is considered to be a separate entity. Whereas ARF is known to cause carditis, the risk of carditis in adult poststreptococcal ReA is unknown. Consequently, the prevailing recommendations regarding long-term antibiotic prophylaxis in poststreptococcal ReA are imprecise...

Imaging cardiac resynchronization therapy.
Abraham T, Kass D, Tonti G, Tomassoni GF, Abraham WT, Bax JJ, Marwick TH
Although a prognostic benefit has been shown from cardiac resynchronization therapy, questions are often directed toward the prediction of symptomatic or functional benefit. Recent multicenter trials have shown the pitfalls of current mechanical markers of left ventricular synchrony, but these negative trial results have not marked the conclusion of efforts to predict outcome. Potential new contributors to the assessment of mechanical synchrony include echocardiographic and magnetic resonance te...

Mannose binding lectin deficiency and triglyceride-rich lipoprotein metabolism in normolipidemic subjects.
Alipour A, van Oostrom AJ, Van Wijk JP, Verseyden C, Plokker HW, Jukema JW, Rabelink AJ, Castro Cabezas M
Mannose binding lectin (MBL) is one of the three initiators of complement activation and is therefore closely linked to inflammation. MBL deficiency has been associated with the generation of atherosclerosis. Since atherosclerosis, the complement system and postprandial lipemia are linked to inflammation, we studied postprandial lipoprotein metabolism in MBL deficiency. An observational study was carried out in 107 volunteers (21% MBL deficient). Classical cardiovascular risk factors were not di...
