Enhancing the efficacy of integrative improvisational music therapy in the treatment of depression : study protocol for a randomised controlled trial
2019
Abstract Background Depression is among the leading causes of disability worldwide. Not all people with depression respond adequately to standard treatments. An innovative therapy that has shown promising results in controlled trials is music therapy. Based on a previous trial that suggested beneficial effects of integrative improvisational music therapy (IIMT) on short and medium-term depression symptoms as well as anxiety and functioning, this trial aims to determine potential mechanisms of and improvements in its effects by examining specific variations of IIMT. Methods/design A 2 × 2 factorial randomised controlled trial will be carried out at a single centre in Finland involving 68 adu…
Acute extrahepatic infectious or inflammatory diseases are a cause of transient mosaic pattern on CT and MR imaging related to sinusoidal dilatation …
2015
To report the association of a mosaic enhancement pattern on contrast-enhanced CT or MR imaging and hepatic sinusoidal dilatation (SD) with acute inflammatory conditions affecting extrahepatic organs. From 2007 to 2012, patients with acute inflammatory diseases who underwent contrast-enhanced CT and/or MRI of the liver with a mosaic enhancement pattern were selected. Clinico-biological and other imaging features were collected at diagnosis and during follow-up. Sixteen patients were included (15 women, median age 27 years; range 18–68). Five women (33 %) were receiving oral contraceptives. Acute inflammatory diseases included pyelonephritis (n = 10), pancreatitis (n = 2), pneumonia (n = 1),…
Two-dimensional echocardiographic evaluation of left ventricular ejection fraction by the ellipsoid single-plane algorithm: a reliable method for ass…
1995
The reliability of two-dimensional (2D) echocardiographic estimation of left ventricular ejection fraction (EF) is commonly recognized, but no satisfactory data are available about the accuracy of low or very low EF values determined by 2D echocardiography (ECHO-EF). The purpose of our study was to assess the reliability of low ECHO-EF values obtained using a simple time-economical algorithm such as the ellipsoid single-plane area-length method. Radionuclide angiography (RAD-EF) was taken as the standard of comparison. We studied 59 consecutive patients (31 women and 28 men) referred to our echocardiographic laboratory. Both 2D echocardiography and radionuclide angiography were blindly perf…
Relevance of new recommendations on routine antenatal prevention of rhesus immunization: an appraisal based on a retrospective analysis of all cases …
2008
Abstract Objective To assess the potential impact of new guidelines recommending routine antenatal prophylaxis at 28 weeks of pregnancy on incidence, consequences and cost of rhesus immunization. Study design All rhesus immunizations of 224,500 ongoing pregnancies in two neighbouring administrative areas in France between 2000 and 2006 were enrolled in this retrospective study. To determine the aetiology of immunization and to specify when sensitization occurred, we searched sensitizing events between the last negative and the first positive red-cell antibody test results. Perinatal consequences and costing were also analyzed. Results From 138 rhesus negative women bearing anti-D antibodies…
Improved land surface emissivities over agricultural areas using ASTER NDVI
2006
Abstract Land surface emissivity retrieval over agricultural regions is important for energy balance estimations, land cover assessment and other related environmental studies. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) produces images of sufficient spatial resolution (from 15 m to 90 m) to be of use in agricultural studies, in which fields of crops are too small to be well-resolved by low resolution sensors. The ASTER project generates land surface emissivity images as a Standard Product (AST05) using the Temperature/Emissivity Separation (TES) algorithm. However, the TES algorithm is prone to scaling errors in estimating emissivities for surfaces with low s…
Accuracy of ASTER Level-2 thermal-infrared Standard Products of an agricultural area in Spain
2007
Abstract The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) collects five-channel thermal-infrared images that are calibrated, corrected for atmospheric effects, and then converted to land surface temperature and emissivity products by the ASTER Temperature/Emissivity Separation (TES) algorithm. TES scales low- and high-contrast surfaces differently, and has been validated over water (low contrast) and rock (high contrast). Performance of TES over agricultural areas, however, has not been evaluated specifically. To address this issue, field measurements of “ground truth” were made over bare soil in addition to green grass, alfalfa and corn, at an agricultural researc…
Vegetation dynamics from NDVI time series analysis using the wavelet transform
2009
A multi-resolution analysis (MRA) based on the wavelet transform (WT) has been implemented to study NDVI time series. These series, which are non-stationary and present short-term, seasonal and long-term variations, can be decomposed using this MRA as a sum of series associated with different temporal scales. The main focus of the paper is to check the potential of this MRA to capture and describe both intra- and inter-annual changes in the data, i.e., to discuss the ability of the proposed procedure to monitor vegetation dynamics at regional scale. Our approach concentrates on what wavelet analysis can tell us about a NDVI time series. On the one hand, the intra-annual series, linked to th…
Emissivity measurements of several soils and vegetation types in the 8–14, μm Wave band: Analysis of two field methods
1997
Abstract The two variants of the box method (with one and two lids) has been rigorously analyzed. As a result of this analysis, a correction factor that takes into account the nonideality of the materials used for the box, as well as its geometry, has been derived A simple method for determining the effective downward atmospheric temperature that uses only the temperature measurement at the zenith also has been proposed. Finally, by using one of the two variants of the box method, 72 in situ emissivity measurements in the 8–14 pin wave-band region of typical vegetation, soils, and rocks of Europe and South America, has been obtained. The use of these data for the ernissivity correction of s…
Tectonic control over large-scale diffuse degassing in eastern Sicily (Italy)
2002
Eastern Sicily (southern Italy) is characterised by the presence of many natural gas emissions (mofettes, mud volcanoes). These gases are mostly carbon dioxide and methane, with minor amounts of helium, hydrogen, carbon monoxide and hydrocarbons. In this study, the extent and orientation of soil gas anomalies (He and CO2) were investigated on a wide area (approximately 110 km2) located just SW of Mt. Etna. From a structural point of view, this area lays on a typical foredeep–foreland system that marks the boundary between the southern part of the Eurasian plate and the northern part of the African plate in the central Mediterranean. No tectonic structure was revealed in this area by surface…
Étude comparative des politiques éducatives d'inclusion en France et en Afrique subsaharienne
2010
Ce travail présente un projet de recherche, en cours de réalisation, sur la comparaison entre les politiques éducatives d'inclusion des enfants en situation d'handicap en France et dans deux pays d'Afrique subsaharienne : l'Éthiopie et le Cameroun. Il s'intéresse à l'étude mécanismes mis en place par ces politiques nationales pour favoriser l'insertion, le développement et la réussite scolaire de ces enfants. Les résultats de l'étude exploratoire réalisée en Éthiopie ont montré que l'appropriation du concept d'éducation inclusive et la mise en ouvre effective d'une politique d'inclusion connaissent des limites, en dépit de la prise en compte des besoins éducatifs spéciaux dans le plan de dé…
