PERSISTENT RIGHT AORTIC ARCH ASSOCIATED WITH AN ABERRANT LEFT SUBCLAVIAN ARTERY ARISING FROM A PATENT DUCTUS ARTERIOSUS IN A PUPPY Rizza M.*, Claeys S.**, Billen F.***, Mc Entee K. ***, Bolen G.* *Diagnostic Imaging Section, **Small Animal Surgery Section, ***Small Animal Internal Medicine Section, Department of Clinical Sciences (Companion Animal and Equides), Faculty of Veterinary Medicine, University of Liege, Belgium. Introduction Vascular anomalies develop during foetal development and single or multiple aberrant vessels can be present. Persistent right aorta arch (PRAA) represents over 90% of described vascular ring anomalies and can be accompanied by a left ligamentum arteriosum or a patent left ductus arteriosus (approximately 10% of patients) that causes oesophageal entrapment and secondary sub-obstruction. Radiography is an effective means of detecting vascular ring anomalies when oesophageal dilation and left-sided tracheal displacement are visible. Computed tomography angiography (CTA) is necessary to confirm the nature and the patency of the vascular anomalies present and to identify which of the identified anomalies is causing the clinical signs. Materials and methods A 3.5-month-old, male French Bulldog was presented for regurgitation and vomiting since weaning. Besides a low body score, physical exam was unremarkable. Hypoglycemia was observed on routine blood analysis. Thoracic radiographs and CTA of the thorax were performed. Results The radiographs revealed severe oesophageal dilation cranial to the base of the heart and a ventral and left-sided tracheal displacement. A congenital oesophageal diverticulum secondary to a vascular anomaly was suspected. CTA showed multiple vascular anomalies. A PRAA was observed. An aberrant right subclavian artery (ARSA) was identified originating from the PRAA next to the brachiocephalic trunk. A patent left-to-right patent ductus arteriosus (PDA) was detected between the aorta and the pulmonary trunk and an aberrant left subclavian artery (ALSA) originated from the PDA. The oesophagus was compressed between the PDA and the trachea and was dilated cranially to this narrowing. Endoscopy revealed severely esophageal distension cranially to an extraluminal stenosis. Surgery was performed to ligate and cut the PDA. Discussion Seven types of vascular ring anomaly are described: types I - III have a PRAA, type IV has a double aortic arch, and types V -VII have a left aortic arch with combinations of persistent right ligamentum arteriosum and right subclavian arteries. In the patient described here, the vascular ring anomalies are a novel variant of the defined types. To the authors’ knowledge, an ALSA originating from a PDA has not been described previously. The severe compression of the oesophagus with severe dilation cranial to the heart was caused by the PDA and was resolved by surgical intervention. In conclusion, CTA is necessary to determine which vascular anomalies are present and to identify which of these anomalies is responsible for the clinical signs. This technique enables accurate pre-operative planning. Pownder S. Scrivani PV. Non-selective computed tomography angiography of a vascular ring anomaly in a dog.

BACKGROUND AND OBJECTIVE: Early recognition of the ineffectiveness of chemotherapy could result in lower cumulative drug toxicity and tumor burden at the start of salvage therapy, which might improve clinical outcome. Therefore, we studied the value of (18)F-FDG PET for early evaluation of response in patients with non-Hodgkin's lymphoma (NHL). DESIGN AND METHODS: We studied 28 patients by (18)F-FDG PET after a median of 3 cycles of polychemotherapy. The presence or absence of abnormal (18)F-FDG uptake was correlated to clinical outcome (median follow-up: 17.5 months, range 4-47 months). RESULTS: Five of 28 patients still had increased (18)F-FDG uptake in one or more sites previously shown to be involved by lymphoma at baseline evaluation. Only one of these five patients entered complete remission (CR), whereas among the 23 patients with negative (18)F-FDG PET studies, two died of toxicity during chemotherapy and all the others entered clinical CR (p<0.00001). All five patients with and 7/21 patients without residual abnormal (18)F-FDG uptake relapsed or reprogressed (positive predictive value for relapse: 100%, negative predictive value: 67%). By Kaplan-Meier analysis, progression-free survival (PFS) at 1 and 2 years was respectively 20+/-18% and 0% for (18)F-FDG PET positive patients and 81+/-9% and 62+/-12% for (18)F-FDG PET negative patients (p=0.0001). Overall survival (OS) at 1 and 2 years was respectively 20+/-18% and 0% for (18)F-FDG PET positive and 87+/-7% and 68+/-11% for (18)F-FDG PET negative patients (p<0.0001). INTERPRETATION AND CONCLUSIONS: Persistent tumoral (18)F-FDG uptake after a few cycles of polychemotherapy is predictive of CR, PFS and OS in NHL. Further studies are warranted to determine whether (18)F-FDG PET has a predictive value independent from conventional prognostic factors. However, the sensitivity of qualitative (18)F-FDG PET imaging in identifying patients with a poor outcome was insufficient. Earlier evaluation after only one cycle of chemotherapy and quantitative analysis might increase the sensitivity of 18F-FDG PET is predicting treatment failure.

Several studies showed that it is more difficult to retrieve semantic information from recognized voices than from recognized faces. However, earlier studies that investigated the recall of biographical information following person recognition used stimuli that were pre-experimentally familiar to the participants, such as famous people’s voices and faces. The present study was designed in order to allow a stricter control of frequency exposure with both types of stimuli (voices and faces). In the present study, subjects had to associate lexical (i.e., name) and semantic information (i.e., occupation) with faces or voices. When asked later to recall semantic information being cued by the person’s names, participants provided significantly more occupations for the targets that had been previously associated with faces than with voices. These results and their implications for current Interactive Activation and Competition person recognition models are discussed. Finally, the potential role of the relative distinctiveness of voices and faces is also considered. [less ▲]Detailed reference viewed: 49 (10 ULg)

This paper reports on the use of a Web 2.0 artifact by nine 14/15 year-old pupils in a formal learning context. The gathered data provides a first appreciation of how the participants saw the action of tagging resources as affecting four dimensions of their learning experience: satisfaction, feeling of learning, effects on memorization and understanding and personalization of the learning sequence. Based on these self-reported judgments, a discussion is opened on the mere decision to divert highly complex Web 2.0 tools into "ordinary" learning Tools.

Personalization of learning has become a prominent issue in the educational field, at various levels. This article elaborates a different view on personalisation than what usually occurs in this area. Its baseline is that personalisation occurs when learning turns out to become personal in the learner's mind. Through a literature survey, we analyze constitutive dimensions of this inner sense of personalisation. Here, we devote special attention to confronting learners with tracked information. Making their personal interaction footprints visible contrasts with the back-office usage of this data by researchers, instructors or adaptive systems. We contribute a prototype designed for the Moodle platform according to the conceptual approach presented here. [less ▲]Detailed reference viewed: 30 (5 ULg)

This paper presents the main results of a questionnaire survey that sought to evaluate secondary school teachers’ familiarity with the notion of personalised learning and to relate it to personal, sociological and professional characteristics. The outcomes of this work are both an exploratory study aimed at defining more focused questions about the theme of personalisation, and the first tryout of the questionnaire designed to gather data. Although this was thus a preliminary study which did not lay claim to any more general scope, it still enables some hypotheses to be framed and examined in the light of the answers of 43 practitioners. The appendix provides the full questionnaire on personalisation, as distributed to participants. [less ▲]Detailed reference viewed: 18 (3 ULg)

If lifestyle changes are not effective for maintaining glycaemic control, metformin is recommended as the first glucose-lowering drug to use in a patient with type 2 diabetes, if the patient has no contraindications—eg, renal impairment or hypoxic disorders.1 However, the glucose-lowering response to metformin can vary greatly between patients, with some people responding poorly to this biguanide. Because of the well known therapeutic inertia with respect to pharmacological treatment of diabetes, insufficient glucose control might persist for a long time before any treatment adjustment is made in people who respond poorly to metformin monotherapy.

Recent research on autonoetic consciousness indicates that the ability to remember the past and the ability to project oneself into the future are closely related. The purpose of the present study was to confirm this proposition by examining whether the relationship observed between personality and episodic memory could be extended to episodic future thinking and, more generally, to investigate the influence of personality traits on self-information processing in the past and in the future. Results show that Neuroticism and Harm Avoidance predict more negative past memories and future projections. Other personality dimensions exhibit a more limited influence on mental time travel (MTT). Therefore, our study provide an additional evidence to the idea that MTT into the past and into the future rely on a common set of processes by which past experiences are used to envision the future.

This study provides evidence that personality traits associated with responsiveness to conscious reward cues also influence responsiveness to unconscious reward cues. Participants with low and high levels of Novelty Seeking (NS) performed updating tasks in which they could either gain 1 euro or 5 cents. Gains were presented either supraliminally or subliminally at the beginning of each trial. Results showed that low NS participants performed better in the high-reward than in the low-reward condition, whereas high NS participants’ performance did not differ between reward conditions. Interestingly, we found that low NS participants performed significantly better when rewards were presented unconsciously, whereas high NS participants’ performance did not differ whether reward cues were presented subliminally or supraliminally. Our findings highlight the necessity to take personality into account in unconscious cognition research. They also suggest that whether implicit and explicit motives have similar or complementary influences might be determined by individual differences. [less ▲]Detailed reference viewed: 57 (13 ULg)

OBJECTIVES: Several studies reported that personality modulates responses to emotional stimuli, including cognitive and attentional aspects of the emotional response. The aim of this study was to refine these results while using visual event-related potentials (ERPs) and referring to Cloninger's personality model. METHODS: ERPs were recorded in 46 normal subjects within a visual oddball protocol with checkerboards as the standard stimuli and pictures selected as neutral, pleasant or unpleasant from the International Affective Picture System as the target stimuli. RESULTS: N200 amplitude was smaller and P300 amplitude was larger following the presentation of pleasant pictures in low-harm avoidance but not high-harm avoidance subjects. CONCLUSIONS: These results support the idea that both automatic and selective cognitive processing of emotional pictures is modulated by personality. [less ▲]Detailed reference viewed: 56 (6 ULg)

As personality may predispose, precipitate or perpetuate substance abuse and/or dependence, and as it is considered to remain stable across the years in a given subject, potential links with the drug of choice may help screen future patients before drug consumption. The present study compared three groups: 42 patients with heroin dependence (mean age: 31.2; standard deviation (SD): 5.5; 10 females), 37 patients with alcohol dependence (mean age 44.2; SD: 9.1; 9 females) and 83 subjects from a random population sample (mean age: 38.8; SD: 6.9; 20 females). Personality was measured by Cloninger's Temperament and Character Inventory (TCI). Pillai's MANCOVA with age as a covariate and gender as a cofactor was highly significant. Univariate ANOVA analyses using TCI dimensions as dependent variable showed most variables to vary in parallel for the two patient groups in comparison with controls. Post-hoc tests showed heroin patients to score higher in Novelty-Seeking and Self-Directedness than alcohol patients. Sub-dimensions Exploratory Excitability, Fear of the Uncertain, Responsibility, Congruent Second Nature and Transpersonal Identification were also significantly different in the two patient samples. Logistic regression showed Exploratory Excitability to segregate up to 76% of heroin patients from alcohol patients. In conclusion, personality profiles were linked to some preferential choice of drug and personality screening might be tested in preventive strategies. [less ▲]Detailed reference viewed: 91 (11 ULg)
