Impact of valvuloarterial impedance on 2-year outcome of patients undergoing transcatheter aortic valve implantation.
Katsanos S, Yiu KH, Clavel MA, Rodés-Cabau J, Leong D, van der Kley F, Ajmone Marsan N, Bax JJ, Pibarot P, Delgado V
Background: Elderly patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) often have increased calcification and fibrosis of the aorta. Indices that account for the severity of valvular obstruction and systemic vascular impedance may better assess total left ventricular afterload. The aims of the present study were to evaluate changes in valvuloarterial impedance (Zva), systemic arterial compliance, and systemic vascular resistance after TAVI and to inves...

Exercise-resembling effects of periodic somatosensory stimulation in heart failure.
Gademan MG, van Exel HJ, van de Vooren H, Haest JC, van Pelt J, van der Laarse A, Cannegieter SC, Lucas CM, Somer S, Verwey HF, Schalij MJ, van der Wall EE, Swenne CA
Background: The mechanism of the beneficial effects of exercise training on autonomic derangement and neurohumoral activation in chronic heart failure (CHF) is largely unexplained. In our here-presented hypothesis-generating study we propose that part of these effects is mediated by the exercise-accompanying somatosensory nerve traffic. To demonstrate this, we compared the effects of periodic electrical somatosensory stimulation in patients with CHF with the effects of exercise training and with...

Risk factors for the displacement of fractures of both bones of the forearm in children.
Colaris JW, Allema JH, Reijman M, Biter LU, de Vries MR, van de Ven CP, Bloem RM, Verhaar JA
Forearm fractures in children have a tendency to displace in a cast leading to malunion with reduced functional and cosmetic results. In order to identify risk factors for displacement, a total of 247 conservatively treated fractures of the forearm in 246 children with a mean age of 7.3 years (sd 3.2; 0.9 to 14.9) were included in a prospective multicentre study. Multivariate logistic regression analyses were performed to assess risk factors for displacement of reduced or non-reduced fractures i...

CD8(+) T cells characterize early smoking-related airway pathology in patients with asthma.
Ravensberg AJ, Slats AM, van Wetering S, Janssen K, van Wijngaarden S, de Jeu R, Rabe KF, Sterk PJ, Hiemstra PS
Background: Smoking in asthma occurs frequently and is associated with increased symptom severity, an impaired response to corticosteroids, and accelerated lung function decline. Airway pathology in smoking asthmatics is characterized by neutrophilia and epithelial changes such as goblet cell hyperplasia and increased proliferation. Bronchial CD8(+) T cells are implicated in lung function decline in asthma and COPD. We hypothesized that smoking modifies airway inflammation in asthma by increasin...

Effect of atrioventricular and ventriculoventricular delay optimization on clinical and echocardiographic outcomes of patients treated with cardiac resynchronization therapy: a meta-analysis.
Auger D, Hoke U, Bax JJ, Boersma E, Delgado V
Background: Optimization of atrioventricular (AV) and ventriculoventricular (VV) delays of cardiac resynchronization therapy (CRT) devices maximizes left ventricular filling and stroke volume. However, the incremental value of these optimizations over empiric device programming remains unclear. The objective of this analysis was to perform a systematic review and meta-analysis of the effects of AV and VV delay optimization on clinical and echocardiographic end points of patients with heart failu...

Display of alcohol use on Facebook: a content analysis.
Beullens K, Schepers A
The present study has two main objectives. First, to examine how alcohol use is portrayed in the visual and textual references on Facebook, and second, to determine how friends react to these alcohol-related postings. A theoretically based content analysis of 160 Facebook profiles generated 2,575 pictures and 92 status updates referring to alcohol use, which represented about 6.50% of the pictures in the total sample and 2.90% of the status updates. These visual and textual references, as well a...

Peak and fixed-time high-sensitive troponin for prediction of infarct size, impaired left ventricular function, and adverse outcomes in patients with first ST-segment elevation myocardial infarction receiving percutaneous coronary intervention.
Boden H, Ahmed TA, Velders MA, van der Hoeven BL, Hoogslag GE, Bootsma M, le Cessie S, Cobbaert CM, Delgado V, van der Laarse A, Schalij MJ
The clinical use of advanced imaging modalities for early determination of infarct size and prognosis is limited. As a specific indicator of myocardial necrosis, cardiac troponin T (cTnT) can be used as a surrogate measure for this purpose. The present study sought to investigate the use of peak and serial 6-hour fixed-time high-sensitive (hs) cTnT for estimation of infarct size, left ventricular (LV) function, and prognosis in consecutive patients with ST-segment elevation myocardial infarction...

Citation analysis may severely underestimate the impact of clinical research as compared to basic research.
van Eck NJ, Waltman L, van Raan AF, Klautz RJ, Peul WC
Background: Citation analysis has become an important tool for research performance assessment in the medical sciences. However, different areas of medical research may have considerably different citation practices, even within the same medical field. Because of this, it is unclear to what extent citation-based bibliometric indicators allow for valid comparisons between research units active in different areas of medical research. Methodology: A visualization methodology is introduced that reve...

Pentaerythritol tetranitrate (PETN) profiling in post-explosion residues to constitute evidence of crime-scene presence.
Brust H, van Asten A, Koeberg M, van der Heijden A, Kuijpers CJ, Schoenmakers P
Pentaerythritol tetranitrate (PETN) and its degradation products are analyzed to discriminate between residues originating from PETN explosions and residues obtained under other circumstances, such as natural degradation on textile, or after handling intact PETN. The degradation products observed in post-explosion samples were identified using liquid chromatography-mass spectrometry as the less-nitrated analogues of PETN: pentaerythritol trinitrate (PETriN), pentaerythritol dinitrate (PEDiN) and...

Ruptured aneurysm of the right coronary sinus of Valsalva in a child with Down syndrome.
Lahrouchi N, Rammeloo LA, Koolbergen DR, Hruda J
Aneurysms of one of the aortic sinuses of Valsalva are rare congenital or acquired lesions. Here we present the case of an adolescent with Down syndrome with ruptured aneurysm of the right coronary sinus into the right atrium. All sinuses of Valsalva were normal during cardiological screening owing to Down syndrome at the age of 2 weeks. Paediatricians should have a low threshold for referring patients with Down syndrome for cardiac re-evaluation because of the new onset of cardiac symptoms or c...

Bright ion channels and lipid bilayers.
Szymański W, Yilmaz D, Koçer A, Feringa BL
If we look at a simple organism such as a zebrafish under a microscope, we would see many cells working in harmony. If we zoomed in, we would observe each unit performing its own tasks in a special aqueous environment isolated from the other units by a lipid bilayer approximately 5 nm thick. These confined units are social: they communicate with one another by sensing and responding to the chemical changes in their environment through receptors and ion channels. These channels control the highly...

Protease-activated receptor (PAR)2, but not PAR1, is involved in collateral formation and anti-inflammatory monocyte polarization in a mouse hind limb ischemia model.
van den Hengel LG, Hellingman AA, Nossent AY, van Oeveren-Rietdijk AM, de Vries MR, Spek CA, van Zonneveld AJ, Reitsma PH, Hamming JF, de Boer HC, Versteeg HH, Quax PH
Aims: In collateral development (i.e. arteriogenesis), mononuclear cells are important and exist as a heterogeneous population consisting of pro-inflammatory and anti-inflammatory/repair-associated cells. Protease-activated receptor (PAR)1 and PAR2 are G-protein-coupled receptors that are both expressed by mononuclear cells and are involved in pro-inflammatory reactions, while PAR2 also plays a role in repair-associated responses. Here, we investigated the physiological role of PAR1 and PAR2 in...
