BACKGROUND: Few European studies have investigated how cardiovascular risk factors (CRF) in adults relate to those observed in younger generations. OBJECTIVE: To explore this issue in a Swiss region using two population health surveys of 3636 adolescents ages 9-19 years and 3299 adults ages 25-74 years. METHODS: Age patterns of continuous CRF were estimated by robust locally weighted regression and those of high-risk groups were calculated using adult criteria with appropriate adjustment for children. RESULTS: Gender differences in height, weight, blood pressure, and HDL cholesterol observed in adults were found to emerge in adolescents. Overweight, affecting 10-12% of adolescents, was increasing steeply in young adults (three times among males and twice among females) in parallel with inactivity. Median age at smoking initiation was decreasing rapidly from 18 to 20 years in young adults to 15 in adolescents. A statistically significant social gradient in disfavor of the lower education level was observed for overweight in all age groups of women above 16 (odds ratios (ORs) 2.4 to 3.3, P < 0.01), for inactivity in adult males (ORs 1.6 to 2.0, P < 0.05), and for regular smoking in older adolescents (OR 1.9 for males, 2.7 for females, P < 0.005), but not for elevated blood pressure. CONCLUSION: Discontinuities in the cross-sectional age patterns of CRF indicated the emergence of a social gradient and the need for preventive actions against the early adoption of persistent unhealthy behaviors, to which low-educated girls and women are particularly exposed.

OBJECTIVES: To evaluate the role of endothelin-1 (ET-1) in hypertension, we investigated density and distribution of ETA and ETB receptors in hearts and kidneys of deoxycorticosterone acetate (DOCA)-salt and 1 kidney -- 1 clip (1K1C) hypertensive rats. METHODS: Five groups of uninephrectomized Wistar rats were put on a low salt diet. Three groups of rats drank tap water and two groups received saline. One group of each regimen received DOCA subcutaneously and two corresponding groups without DOCA served as controls. The fifth group of rats had the renal artery clipped to induce 1K1C hypertension. At 6 weeks, mean arterial pressure (MAP) was recorded and membrane binding assays using 125I-ET-1 were carried out. RESULTS: MAP was increased from control 122 +/- 3 to 155 +/- 6 and 218 +/- 11 mmHg in DOCA-salt and 1K1C rats, respectively, and cardiac weight index was increased. ETA receptors were predominantly expressed in the heart, whereas ETB receptors were predominant in the kidney. In the kidneys, the density of the ETB receptor subtype was upregulated in DOCA-salt and 1K1C rats from 160 +/- 8 to 217 +/- 12 and 190 +/- 2 fmol/mg (P < 0.05), respectively, and ETA tended to be downregulated (P = 0.057). Plasma renin activity was decreased in DOCA-salt rats from 17 +/- 3 to 0.17 +/- 0.01 ng/ml per h and increased in 1K1C rats on low salt diet to 30 +/- 5 ng/ml per h. CONCLUSIONS: Since ETB is the predominant endothelin receptor in the kidneys, upregulation of the ETB receptor mediating vasodilation and downregulation of the ETA receptor mediating vasoconstriction would be compatible with a mainly renal counter-regulatory effect of endothelin-1 to hypertension. Both low and high renin models of hypertension may be affected.

Fibrin sealant is used in many areas of surgery. We present a novel aspect of flap insetting in the ischial region using fibrin spray to seal the transferred tissue. We analyzed 10 patients suffering from decubital ulcers and assessed drainage output, time of drain removal, as well as complications following fasciocutaneous flap surgery. Patients were randomized to receive sprayed fibrin glue (study group) or not (control group) before wound closure. The mean drainage time was 4 +/- 1 days in the study group and 6 +/- 1 days in the control group ( P = 0.06). The mean drainage volume was 100 +/- 20 mL in the study group and 168 +/- 30 mL in the control group ( P < 0.01). Fibrin sealant led to reduced drainage volumes and duration of drainage, indicating a beneficial effect of the application of fibrin glue in fasciocutaneous flap surgery for pressure sore coverage.

Sophisticated magnetic resonance tagging techniques provide powerful tools for the non-invasive assessment of the local heartwall motion towards a deeper fundamental understanding of local heart function. For the extraction of motion data from the time series of magnetic resonance tagged images and for the visualization of the local heartwall motion a new image analysis procedure has been developed. New parameters have been derived which allows quantification of the motion patterns and are highly sensitive to any changes in these patterns. The new procedure has been applied for heart motion analysis in healthy volunteers and in patient collectives with different heart diseases. The achieved results are summarized and discussed.

A two stage sampling strategy is necessary in order to optimize the study of distribution of pollution in soils and groundwater. First, detailed sampling from a limited area coupled with statistical analysis of the data are used to determine the microvariability of the parameter(s). The results from this detailed analysis are then used to calculate the optimal spacing between samples for the larger scale study. This two stage sampling strategy can result in significant financial savings during subsequent soil or groundwater remediation. This combined sampling and statistical analysis approach is illustrated with an example from a heavy metal contaminated site.

Soft tissue sarcomas (STS) with complex genomic profiles (50% of all STS) are predominantly composed of spindle cell/pleomorphic sarcomas, including leiomyosarcoma, myxofibrosarcoma, pleomorphic liposarcoma, pleomorphic rhabdomyosarcoma, malignant peripheral nerve sheath tumor, angiosarcoma, extraskeletal osteosarcoma, and spindle cell/pleomorphic unclassified sarcoma (previously called spindle cell/pleomorphic malignant fibrous histiocytoma). These neoplasms show, characteristically, gains and losses of numerous chromosomes or chromosome regions, as well as amplifications. Many of them share recurrent aberrations (e.g., gain of 5p13-p15) that seem to play a significant role in tumor progression and/or metastatic dissemination. In this paper, we review the cytogenetic, molecular genetic, and clinicopathologic characteristics of the most common STS displaying complex genomic profiles. Features of diagnostic or prognostic relevance will be discussed when needed.

Popularisée par l'usage extensif (et de ce fait quelque peu galvaudé) qu'en fit Gérard Genette en narratologie littéraire, la « diégèse » constitue certes la notion vedette des filmologues, mais elle fut pendant plusieurs décennies le lieu d'une certaine occultation de son champ originel en raison des appropriations non référencées qu'en firent poéticiens et sémiologues. En suivant le fil historiographique des différents emplois et acceptions de cette notion associée à Etienne Souriau dans l'espace francophone, le présent article propose un état des lieux qui, par la petite porte d'une entrée terminologique, entend s'interroger sur les conséquences théoriques des variations que le terme « diégèse » a subies et, plus généralement, sur la question du statut octroyé au courant filmologique. En examinant les différentes implications de la définition première qu'il s'agit parfois de délester de sens dont on l'a ultérieurement investie, cet article tente de montrer que le cadre dans lequel la diégèse a été conceptualisée contient des potentialités théoriques qui n'ont pas encore été épuisées aujourd'hui, et qui convergent avec certains champs d'étude récents (comme celui de la logique des mondes possibles) dont l'application au cinéma n'a probablement jamais été aussi pertinent qu'à l'ère des images de synthèse, des mondes virtuels et des environnements de jeux vidéo.
