Background: Several matrix metalloproteinases ( MMPs) are involved in the pathogenesis of chronic obstructive pulmonary disease ( COPD). In mice, MMP-12 plays a crucial role in the development of cigarette smoke induced emphysema. A study was undertaken to investigate the role of MMP-12 in the development of COPD in human smokers. Methods: Induced sputum samples were collected from patients with stable COPD (n = 28), healthy smokers ( n = 14), never smokers ( n = 20), and former smokers ( n = 14). MMP-12 protein levels in induced sputum were determined by ELISA and compared between the four study groups. MMP-12 enzymatic activity in induced sputum was evaluated by casein zymography and by cleaving of a fluorescence quenched substrate. Results: Median (IQR) MMP-12 levels were significantly higher in COPD patients than in healthy smokers, never smokers, and former smokers (17.5 (7.1 - 42.1) v 6.7 (3.9 - 10.4) v 4.2 (2.4 - 11.3) v 6.1 (4.5 - 7.6) ng/ml, p = 0.0002). MMP-12 enzymatic activity was significantly higher in patients with COPD than in controls (4.11 (1.4 - 8.0) v 0.14 (0.1 - 0.2) mu g/ml, p = 0.0002). Conclusion: MMP-12 is markedly increased in induced sputum from patients with stable COPD compared with controls, suggesting a role for MMP-12 in the development of COPD in smokers. [less ▲]

See detailElevated Plasma Alpha 1-Acid Glycoprotein Levels: Lack of Connection to Resistance to Vecuronium Blockade Induced by Anticonvulsant Therapy

This study was designed to investigate the relationships among anticonvulsant therapy, plasma alpha 1-acid glycoprotein (AAG) levels, and resistance to vecuronium blockade. Thirty-one patients scheduled for routine neurosurgery were included in the study. The patients were treated (TG; n = 20) with phenytoin (n = 15) and/or carbamazepine (n = 4) and/or phenobarbital (n = 3) for > or = 6 days or were left untreated (UG; n = 11, control group). TG patients were further assigned to one of two subgroups according to the plasma anticonvulsant level measured the day before surgery and found to be within (TGW, n = 10) or below (TGB, n = 10) the therapeutic range. Finally, the 31 patients were divided into two more groups according to their plasma AAG levels: higher than (HAAG, n = 17) or within (NAAG, n = 14) the normal range (25-94 mg dl-1). Anesthesia was induced and maintained with propofol and sufentanil. Muscle relaxation was obtained with vecuronium 0.1 mg kg-1. A train-of-four (TOF) stimulation mode at 2 Hz was applied to the ulnar nerve every 15 s, and neuromuscular transmission was assessed using a TOF-Guard accelograph monitor. Plasma AAG concentrations (means +/- SEM) were 103.7 +/- 7.6 mg dl-1 in TG, 80.7 +/- 6.7 mg dl-1 in UG, 95.9 +/- 13.2 mg dl-1 in TGW, 111.6 +/- 7.6 mg dl-1 in TGB. 114.9 +/- 7.4 mg dl-1 in HAAG, and 71.4 +/- 3.8 mg dl-1 in NAAG groups. The differences in plasma AAG concentrations between UG and TG and between HAAG and NAAG groups were statistically significant. No significant relationship was found between plasma AAG levels and phenytoin concentrations (r = -0.26). The time (mean +/- SEM) to recovery of T1 to 25% of control was significantly shorter in TG (28.2 +/- 1.4 min) than in UG (42.2 +/- 3.1 min) but did not differ significantly according to the plasma anticonvulsant level (27.3 +/- 2.0 min in TGW; 29.1 +/- 1.9 min in TGB) and the plasma AAG level 31.7 +/- 1.9 min in HAAG; 35.3 +/- 3.3 min in NAAG). The time for the TOF ratio to recover to 25% yielded similar profiles and statistical significance levels: TG, 32.9 +/- 2.2 min; UG, 51.2 +/- 4.0 min; TGW, 35.0 +/- 3.9 min; TGB, 30.7 +/- 1.8 min; HAAG, 38.1 +/- 3.1 min; NAAG, 42.0 +/- 4.1 min. We conclude that anticonvulsant therapy induces an increase in plasma AAG independently of the plasma anticonvulsant level. However, duration and recovery of vecuronium blockade do not differ according to plasma AAG levels. Consequently, elevated AAG does not contribute to the resistance to vecuronium blockade induced by anticonvulsants. [less ▲]

B-type natriuretic peptide (BNP) is often used as a complementary finding in the diagnostic work-up of patients with aortic stenosis (AS). Whether soluble ST2, a new biomarker of cardiac stretch, is associated with symptomatic status and outcome in asymptomatic AS is unknown. sST2 and BNP levels were measured in 86 patients (74+/-13 years; 59 asymptomatic, 69%) with AS (<1.5 cm2) and preserved left ventricular ejection fraction who were followed-up for 26+/-16 months. Both BNP and sST2 were associated with NYHA class but sST2 (>23 ng/mL, AUC = 0.68, p<0.01) was more accurate to identify asymptomatic patients or those who developed symptoms during follow-up. sST2 was independently related to left atrial index (p<0.0001) and aortic valve area (p = 0.004; model R2 = 0.32). A modest correlation was found with BNP (r = 0.4, p<0.01). During follow-up, 29 asymptomatic patients (34%) developed heart failure symptoms. With multivariable analysis, peak aortic jet velocity (HR = 2.7, p = 0.007) and sST2 level (HR = 1.04, p = 0.03) were independent predictors of cardiovascular events. In AS, sST2 levels could provide complementary information regarding symptomatic status, new onset heart failure symptoms and outcome. It might become a promising biomarker in these patients.

We present the case of a patient who felt faint after a strenuous exercise. A coronary angiography was performed because of an elevated level of troponin, but it failed to demonstrat any significant coronary stenosis. We discuss the effect of strenuous exercise on cardiac biomarkers. Most previous published studies involved young trained populations. The frequency of these abnormalities in older, less trained people is unknown. Moreover, the possible impact of these abnormalities on mid- or long-term outcome is a matter of debate. Seniors practising intensive sport activities should systematically be submitted to a cardiological evaluation. [less ▲]

Unexpected finding or persistence of low human chorionic gonadotropin (hCG) levels is not a rare situation. It requires a clinico-biological approach in order to avoid misunderstandings that could lead to inappropriate diagnostic or therapeutic attitudes. Beyond pregnancy, persistent low levels of hCG may be associated with various benign and malignant conditions, i.e. quiescent gestational trophoblastic disease (QTD), raised pituitary hCG or false positive elevation caused by circulating heterophile antibodies. We report the cases of two non-pregnant patients with low serum hCG. In the first case, hCG levels raised during several years following a spontaneous abortion. The likelihood of heterophilic antibodies interference was ruled out and extensive clinical investigation excluded the presence of a tumour. The diagnosis was QTD. In the second case, elevated hCG came to light as an incidental finding in a women with chronic renal failure and led the clinicians to question the laboratory. The cause was probably an increase in pituitary hCG consecutive to terminal renal failure. These cases illustrate the importance of understanding the biology of the hCG and the causes of its persistent low elevation, which are reviewed in this article. It is essential to demonstrate clinically the presence of a tumour in order to avoid unnecessary and ineffective chemotherapy and/or hysterectomy. [less ▲]

Ce papier se propose d’interroger le rôle que peut avoir un outil audiovisuel dans la production d’un mode d’existence particulier1. Dans notre démarche méthodologique, le chercheur n’est plus un observateur neutre et objectif , il est un apprenant qui, de la rencontre entre son expérience cognitive et l’expérience de vie des acteurs, cherchera comment tient une situation. Mais, plus précisément, comment le chercheur peut –il participer à l’émergence d’un groupe que l’on peut décrire comme se rendant capable d’expliciter ses intérêts sur un mode qui les constituerait éventuellement en affaire publique (Stengers, 2006) ? Cette question nous l’avons posée à travers la possibilité que nous avons entrevue de voir émerger un public (Dewey, 1927) autour de la question de l’élevage « pluri-actif » et du mode d’existence particulier des éleveurs pluri-actifs dans la région gaumaise (au sud de la Belgique). Ceux-ci exercent deux métiers à la fois : ils sont facteur, éducateur ou encore couvreur, et pratiquent l’élevage en plus, « après journée ». Ils nous intéressaient tout particulièrement car, bien que présents dans la région ils sont aussi bien effacés du discours de la profession agricole qu’absents des données statistiques produites par l’administration.

Bereits im vergangenen interdisziplinären Workshop für NachwuchswissenschaftlerInnen, den die Forschungsplattform Elfriede Jelinek 2014 an der Universität Wien veranstaltet hatte (Elfriede Jelinek „Es ist sprechen und aus“), hatte sich eine Arbeitsgruppe intermedialen Fragestellungen in Jelineks Werk gewidmet. Damals ging es vornehmlich um Jelineks Essays zum Film (Susanne Teutsch), ihr Stück Rechnitz (der Würgeengel) (Bettina Wodianka, Aline Vennemann), sowie ihren Roman Die Klavierspielerin (Beate Schirrmacher). Während die Kurztexte und Rechnitz auch dieses Jahr von der Arbeitsgruppe unter Betracht gezogen wurden, kamen zwei Theaterstücke neu hinzu: das bisher wenig beachtete Kein Licht (2011) und das hingegen viel besprochene Die Schutzbefohlenen (2013). Diese Auswahl bestätigt den aktuellen Fokus auf Elfriede Jelineks Theater insbesondere auf ihre aktuellsten Stücke. Thematisch überschnitten sich die Diskussionen der zwei Gruppen eindeutig hinsichtlich der Frage von Körper und Performativität, sowie von Vermittlung und Übersetzung (ausgehend von der so bedeutungsvollen Figur des Boten in Rechnitz). Jedoch geschah auch eine Verlagerung von der medialen und zeitlichen Vermittlung (Übertragung zurückliegender Ereignisse in Körper und Sprache) hin zu einer kulturellen und räumlichen Vermittlung (Übertragung von Ereignissen zwischen verschiedenen Kontinenten). Ähnliches geschah auch bezüglich der Kernfrage der Intermedialität, die in eine breitere historische Perspektive gesetzt wurde (Jelinek und Leonardo da Vinci). Der Nachdruck lag weniger auf medialen Verknüpfungen innerhalb eines Kunstwerkes als auf den Beziehungen zwischen Kunstwerken verschiedener Sparten. Diese Tatsache erklärt auch den im Vergleich zu 2014 leicht veränderten Namen der Arbeitsgruppe, nämlich „(Inter)Medialität“. [less ▲]
