General Road Detection Algorithm, a Computational Improvement

International audienceThis article proposes a method improving Kong et al. algorithm called Locally Adaptive Soft-Voting (LASV) algorithm described in " General road detection from a single image ". This algorithm aims to detect and segment road in structured and unstructured environments. Evaluation of our method over different images datasets shows that it is speeded up by up to 32 times and precision is improved by up to 28% compared to the original method. This enables our method to come closer the real time requirements

Importance of malnutrition and associated diseases in the management of Zenker's diverticulum

AbstractObjectivesTo study the impact of malnutrition on a population treated for Zenker's diverticulum and to look for the causes of persistence or recurrence of dysphagia after endoscopic surgery.Material and methodsThis retrospective study included 30 patients with Zenker's diverticulum treated by endoscopy. All swallowing disorders and manifestations of malnutrition and postoperative improvement in and/or recurrence of symptoms were noted.ResultsNutritional status was evaluated for 26 patients. Before surgery, 54% suffered from malnutrition, which was severe in 31%; 28.6% of the cases with malnutrition showed postoperative complications, versus 8.3% of cases without baseline malnutrition. Ninety percent of patients (n=27) declared complete resolution of symptoms. Nine patients presented recurrence of dysphagia, including 6 with recurrence of Zenker's diverticulum and 3 with, respectively, inclusion body myopathy, esophageal hypertonia and central disease.ConclusionMalnutrition should be quantified and treated before and after surgery for Zenker's diverticulum to prevent complications and decrease mortality. Associated pathologies should be systematically screened for, especially in case of recurrence of swallowing disorder without recurrence of Zenker's diverticulum

Real-time visual detection of vehicles and pedestrians with new efficient adaBoost features

International audienceThis paper deals with real-time visual detection, by mono-camera, of objects categories such as cars and pedestrians. We report on improvements that can be obtained for this task, in complex applications such as advanced driving assistance systems, by using new visual features as adaBoost weak classifiers. These new features, the “connected controlpoints” have recently been shown to give very good results on real-time visual rear car detection. We here report on results obtained by applying these new features to a public lateral car images dataset, and a public pedestrian images database. We show that our new features consistently outperform previously published results on these databases, while still operating fast enough for real-time pedestrians and vehicles detection

Introducing New AdaBoost Features for Real-Time Vehicle Detection

International audienceThis paper shows how to improve the real-time object detection in complex robotics applications, by exploring new visual features as AdaBoost weak classifiers. These new features are symmetric Haar filters (enforcing global horizontal and vertical symmetry) and N-connexity control points. Experimental evaluation on a car database show that the latter appear to provide the best results for the vehicle-detection problem

Adenocarcinoma of the ethmoid sinus: Retrospective study of 42 cases

SummaryObjectivesRetrospective analysis of the oncological results and morbidity of ethmoid sinus adenocarcinoma surgery, and identification of survival factors.Material and methodsForty-two patients were treated from 1990 to 2009. The study covered clinical presentation, medical imaging, histologic data, TNM grade, treatment, morbidity and overall recurrence-free survival.ResultsForty-one men and one woman, with mean age at diagnosis of 61.5 years, were included. 85.7% had been exposed to wood dust. Twenty patients (47.6%) were graded T4 at diagnosis. Thirty-three (78.5%) were treated by surgery followed by radiation therapy; nearly half of these showed recurrence. Overall specific 5-year survival was 44.2% at 5 years and recurrence-free 5-year survival 46.4%. The factors of poor prognosis found were cerebromeningeal or orbital invasion and local recurrence.ConclusionThis series confirms the epidemiological literature on ethmoid adenocarcinoma and the influence of poor prognosis factors. Survival depended directly on local tumor control and seemed to be enhanced on an isolated transfacial approach

Does the commercialization of sport has a decisive influence on the success of social sporting projects? : shown at the Dortmund fan project

Die Kommerzialisierung des Sports hängt stark von dem Einfluss der Medien, der Politik und vom gesellschaftlichen Interesse ab. Erkannt wurde die Werbewirksamkeit des Fußballsports in den 80er Jahren. Deutlich zeichnet sich eine dynamische Entwicklung in der Vermarktung des Sports ab. Zeitsynchron ergab sich durch die Tendenz zur erhöhten Gewaltbereitschaft in den Fußballstadien die Notwendigkeit von sozialsportiven Projekten. Verbände und Organisationen erkannten in der Entwicklung des Zuschauerverhaltens zunehmend die Gefahr für das positive Image des Fußballs. Dieser Problematik wurde durch die Schaffung von Fanprojekten entgegen gewirkt. Nur durch eine nachhaltige Ausrichtung und einer kontinuierlichen Weiterentwicklung können diese dauerhaft bestehen. Analysiert wird am Beispiel des Dortmunder Fan-Projekts, wie die Kommerzialisierung des Fußballsports dazu beiträgt, sozialsportive Projekte erfolgreich umzusetzen. Durch Literaturanalyse und ein Experteninterview wird die These der Arbeit unterstützt, dass die Kommerzialisierung des Sports direkten Einfluss auf sozialsportive Projekte hat

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic: An international, multicenter, comparative cohort study

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Effets d’une intervention orthophonique axée sur l’identification et la compréhension des émotions auprès d’enfants atteints de troubles du spectre de l’autisme

Deficits of emotions understanding are an integral part of Autism Spectrum Disorders (ASD). Many studies have highlighted these deficits, while others have sought to implement interventions to minimize them. Therefore, our project aimed to implement a speech and language therapy intervention directly focused on identifying and understanding emotions on children with ASD and to evaluate the benefits and limitations. An intervention based on five levels of emotions understanding was set up during eight sessions with five children with ASD. The analysis of the results did not allow us to bring out any real benefits, despite very encouraging qualitative observations. An adjustment of our intervention, additional evaluations as well as a larger cohort could be beneficial to continue our project.Les déficits de compréhension des émotions font partie intégrante des troubles du spectre de l’autisme (TSA). De nombreuses recherches ont permis de mettre en avant ces déficits, tandis que d’autres ont cherché à mettre en place des interventions permettant de minimiser ces déficits. Notre projet avait donc pour but de mettre en place une intervention orthophonique directement axée sur l’identification et la compréhension des émotions auprès d’enfants atteints de TSA et d’en évaluer les bénéfices et les limites. Une intervention basée sur cinq niveaux de compréhension émotionnelle a ainsi été mise en place durant huit séances auprès de cinq enfants avec TSA. L’analyse des résultats ne nous a pas permis de mettre en évidence de réels bénéfices, malgré des observations qualitatives très encourageantes. Un ajustement de notre intervention, des évaluations supplémentaires ainsi qu’une cohorte plus importante pourraient être bénéfiques afin de poursuivre notre projet
