Emotional and neuroendocrine regulation in very preterm and full-term infants at six months of age

Emotional and neuroendocrine regulation have been shown to be associated. However, results are inconsistent. This paper explores the functioning and relationships between these two systems in 54 healthy preterm and 25 full-term born infants at six months of age. Results showed significant differences between very preterm and full-term children in emotional intensity and regulation, as well as in neuroendocrine regulation. No evidence of an association between neuroendocrine and emotional regulations was found. Results suggest a possible delay in the maturation of the neuroendocrine system as well as in emotional regulation in very preterm infants.

Low prevalence of behavioural and emotional problems among Swiss paediatric patients with inflammatory bowel disease.

OBJECTIVES: Whether behavioural and emotional maladjustment is more prevalent in children with inflammatory bowel disease (IBD) than in healthy controls remains controversial. The aim of this study was to assess paediatric IBD patients for problems with emotional and behavioural adjustment and to examine associations with clinical and demographic variables. METHODS: Data from paediatric patients with IBD enrolled in the Swiss IBD Cohort Study and the results of both the parent-rated Strengths and Difficulties Questionnaire (SDQ) and the self-reported Child Depression Inventory (CDI) were analysed. Of the 148 registered patients, 126 had at least one questionnaire completed and were included. RESULTS: The mean age of 71 patients with Crohn's disease (44 males, 27 females) was 13.4 years, and 12.8 years for the 55 patients with ulcerative or indeterminate colitis. The mean duration of disease was 1.2 and 2.7 years, respectively. The total score of the SDQ was abnormal in 11.4% of cases compared to 10% in the normal population. Abnormal sub-scores were found in 20.2% of subjects for the domain of emotional problems and in 17.1% for problems with peers. The total CDI T score indicated a significantly lower prevalence of clinical depression in IBD patients than in normal youth. No correlation between the total SDQ scores or the CDI T scores and gender, type or duration of IBD, inflammatory markers or disease scores was found. CONCLUSIONS: The prevalence of problems with behavioural and emotional adjustment among Swiss paediatric IBD patients is low and comparable to that of the normal population.

Selective attention to emotional stimuli: What IQ and Openness do, and emotional intelligence does not

We examined how general intelligence, personality, and emotional intelligence-measured as an ability using the MSCEIT-predicted performance on a selective-attention task requiring participants to ignore distracting emotion information. We used a visual prime in which participants saw a pair of faces depicting emotions; their task was to focus on one of the faces (the target) while ignoring the other (the distractor). Next, participants categorized a string of letters (word or nonword), which was either congruent to the target or the distractor. The speed of response to categorizing the string was recorded. Given the emotional nature of the stimuli and the emotional information processing involved in the task, we were surprised to see that none of the MSCEIT branches predicted performance. However, general intelligence and openness to experience reduced response time.

Emotional attention as a modulatory system of perception

Report for the scientific sojourn carried out at the University Medical Center, Swiss, from 2010 to 2012. Abundant evidence suggests that negative emotional stimuli are prioritized in the perceptual systems, eliciting enhanced neural responses in early sensory regions as compared with neutral information. This facilitated detection is generally paralleled by larger neural responses in early sensory areas, relative to the processing of neutral information. In this sense, the amygdala and other limbic regions, such as the orbitofrontal cortex, may play a critical role by sending modulatory projections onto the sensory cortices via direct or indirect feedback.The present project aimed at investigating two important issues regarding these mechanisms of emotional attention, by means of functional magnetic resonance imaging. In Study I, we examined the modulatory effects of visual emotion signals on the processing of task-irrelevant visual, auditory, and somatosensory input, that is, the intramodal and crossmodal effects of emotional attention. We observed that brain responses to auditory and tactile stimulation were enhanced during the processing of visual emotional stimuli, as compared to neutral, in bilateral primary auditory and somatosensory cortices, respectively. However, brain responses to visual task-irrelevant stimulation were diminished in left primary and secondary visual cortices in the same conditions. The results also suggested the existence of a multimodal network associated with emotional attention, presumably involving mediofrontal, temporal and orbitofrontal regions Finally, Study II examined the different brain responses along the low-level visual pathways and limbic regions, as a function of the number of retinal spikes during visual emotional processing. The experiment used stimuli resulting from an algorithm that simulates how the visual system perceives a visual input after a given number of retinal spikes. The results validated the visual model in human subjects and suggested differential emotional responses in the amygdala and visual regions as a function of spike-levels. A list of publications resulting from work in the host laboratory is included in the report.

The expressions of GABA and glutannate transporters are altered in the spared nerve injury model of neuropathic pain in the rat

Neuropathic pain is a common form of chronic pain, and is unsuccessfully alleviated by usual medications. Mounting evidence strongly point at non-neuronal glial cells in the spinal cord as key actors behind the persistence of pain. In particular, a change in the astrocytic capacity to regulate extracellular concentrations of neurotransmitters might account for the strengthened spinal nociceptive neurotransmission. Therefore, we investigated whether spinal expressions of GABA (GAT) and glutamate (EAAT) transporters were affected in the spared nerve injury (SNI) rat model of neuropathic pain. SNI was induced in male Sprague-Dawley rats by a unilateral section of tibial and common peroneal branches of the sciatic nerve, leaving the sural branch untouched. Western-blot analysis was performed to study the expression of GAT-1 and GAT-3 as well as EAAT-1 and EAAT-2, the main astrocytic GABA and glutamate transporters respectively. Seven days post-surgery, a significant increase in GAT-1, GAT-3 and EAAT-1 expressions is detected in both ipsilateral and contralateral sides of lumbar spinal cord in comparison to sham animals. No change in EAAT-2 signal could be detected. Furthermore, the astrocytic reaction parallels the glutamate and GABA transporters changes as we found an increased GFAP expression compared to the sham condition, in both spinal sides. Together, our results indicate that modifications in GABA and glutamate transport may occur along with SNI-associated painful neuropathy and identify spinal neurotransmitter reuptake machinery as a putative pharmacological target in neuropathic pain.

Emotional modulation of the ability to inhibit a prepotent response during childhood.

The present study examined the bottom-up influence of emotional context on response inhibition, an issue that remains largely unstudied in children. Thus, 62 participants, aged from 6 to 13 years old, were assessed with three stop signal tasks: one with circles, one with neutral faces, and one with emotional faces (happy and sad). Results showed that emotional context altered response inhibition ability in childhood. However, no interaction between age and emotional influence on response inhibition was found. Positive emotions were recognized faster than negative emotions, but the valence did not have a significant influence on response inhibition abilities.

Proverbes, dictons et expressions imagées dans l’enseignement/apprentissage du FLE, dans le secondaire au Cap-Vert.

Pour bien maîtriser une langue, il faut sans doute en avoir une connaissance la plus large possible, ce qui demande alors l’enseignement/apprentissage de tous les éléments qui la composent. Dans ce cas, il est très important de savoir quels sont, parmi ces éléments, ceux qui sont amenés en classe et comment ils y sont présentés. Il y en a certains qui ne fi-gurent pas dans le programme destiné à l’enseignement/apprentissage de la langue fran-çaise. S’ils l’étaient, probablement ils seraient enseignés. Mais, d’après notre constat, non seulement ils ne figurent pas, comme ils ne sont pas ou presque pas traités en cours par l’initiative des professeurs, bien qu’ils soient parmi les éléments les plus importants dans l’apprentissage d’une langue. Très souvent, ce sont ces éléments qui sont à la base de la motivation pour l’apprentissage des langues puisqu’ils constituent, d’une certaine manière, le charme et la beauté d’une langue. Nous en avons pris trois (proverbe, dicton et expres-sion imagée), qui peuvent représenter la manière de vivre ; de penser ; la culture, les cou-tumes et les habitudes d’un peuple. Il faut préciser que ce constat nous l’avons fait depuis longtemps. Par conséquent, nous avons décidé de traduire l’inquiétude que cette problématique provoque chez nous en ce travail de recherche qui a été mené sous le thème de : Proverbes, dictons et expres-sions imagées dans l’enseignement/apprentissage du FLE, dans le secondaire au Cap- Vert. Dans l’ensemble, ce travail est composé de trois parties. Dans la première partie, après les consultations de documents, nous avons proposé une réflexion sur le proverbe, le dicton et l’expression imagée en ce qui concerne leur origine et leur contexte social, temporel, leur durée, et leur situation actuelle par rapport à leur utilisation ou leur étude. Nous en avons également présenté quelques définitions, en insistant sur la distinction entre les mêmes, vu que pendant les recherches, nous avons constaté qu’il y a parfois, une confusion entre eux. Puis, dans la deuxième partie, à travers des enquêtes qui ont été menées sur le terrain dans quelques lycées de Praia, nous avons présenté sous forme d’analyse, la situation ac-tuelle concernant le recours aux proverbes, dictons et expressions imagées par le professeur dans ses cours, bien comme l’intérêt et la motivation des élèves face aux mêmes. Finalement, dans la troisième et dernière partie, nous avons dressé une liste composée de proverbes, dictons et expressions imagées que nous avons fait accompagner de leur pays d’origine, quand cela a été possible. Ils ont été analysés et nous avons essayé de montrer également, l’utilité pratique de leur message, soit pour les élèves à l’école, soit d’une ma-nière plus générale, pour toute la vie dans la société. Pour donner un caractère pratique à notre travail, nous avons fait quelques proposi-tions de techniques d’exploitation de proverbes, dictons et expressions imagées, dans les classes. C’est-à-dire, nous avons essayé d’apporter des suggestions qui peuvent être appli-quées à un éventuel engagement de la part des professeurs ou d’autres intervenants concer-nés à la résolution de la problématique qui a légitimé notre recherche.

Compact matrix expressions for generalized Wald tests of equality of moment vectors

Asymptotic chi-squared test statistics for testing the equality ofmoment vectors are developed. The test statistics proposed aregeneralizedWald test statistics that specialize for different settings by inserting andappropriate asymptotic variance matrix of sample moments. Scaled teststatisticsare also considered for dealing with situations of non-iid sampling. Thespecializationwill be carried out for testing the equality of multinomial populations, andtheequality of variance and correlation matrices for both normal andnon-normaldata. When testing the equality of correlation matrices, a scaled versionofthe normal theory chi-squared statistic is proven to be an asymptoticallyexactchi-squared statistic in the case of elliptical data.

Early repolarization, acute emotional stress and sudden death.

We herein report the case of a 36-year-old man who died suddenly after a fight with another man. Forensic investigations included unenhanced computed tomography, postmortem angiography, autopsy, histology, neuropathology, toxicology, and biochemistry and allowed a traumatic cause of death to be excluded. An electrocardiogram recorded some years prior to death revealed the presence of an early repolarization pattern. Based on the results of all investigations, the cause of death was determined to be cardiac arrhythmia and cardiac arrest during an emotionally stressful event associated with physical assault. Direct third party involvement, however, was excluded, and the manner of death was listed as natural. The case was not pursued any further by the public prosecutor.

CRIMINAL JUSTICE, VICTIM SUPPORT CENTERS, AND THE EMOTIONAL WELLBEING OF CRIME VICTIMS

SUMMARY (Français au-dessous)After the Second World War, the role of the victim in criminal conflict became an objectof interest for academics. But it was only in the 1960s that the importance of providingprotection and assistance to crime victims was highlighted in particular by the victims'movement, which inaugurated a new era of criminal justice in systems throughout the world.Moving beyond just the role of controlling crime and punishing the offender, the criminaljustice system also began to contribute to the victims' rehabilitation and to help the victim tomove on from the event psychologically and emotionally.Although some criminological research has been conducted, to date the effect that thecriminal justice system and victim support services have on the well-being of crime victims isstill uncertain.The current study sought to understand better the healing process of victims of crime, thepotential consequences of their participation on the criminal justice system, and the supportof victim centers. Moreover, it aimed to find out whether the existence of a Victim SupportAct would change the treatment that the victim receives in the criminal justice system. Thusthis research was conducted based in two countries - Switzerland and Brazil - where theoutcome of the victims' movement on the criminal justice system was different, as was theparticipation of the victim in the criminal justice system and the government's provision ofsupport.In order to conduct this research we employed the qualitative method, which is the mostefficient to gather sensitive information. Interviews with crime victims were the main sourceof information. Hearing observation and document research were used as complementarysources.The results of this research show that victims who have contact with the criminal justicesystem and victim services are not more likely to recover than those who had no contact. Thisis to say, the support offered has no major effects; the influence of the criminal justice systemand the victim support services in the emotional well-being of crime victims is rather neutral.However, considering that the sample is not representative, findings are not expected to begeneralized. Instead, findings may give insight to practitioners or to future criminal justicepolicy makers, suggesting what may work to improve the emotional well-being of crimevictims, as well as suggesting further studies.________________________________________________________________________________RÉSUMÉAprès la deuxième guerre mondiale, le rôle de la victime est devenu un objet d'intérêtpour les académiciens. Par contre, c'est seulement dans les années 60 que l'importance defournir de la protection et de l'appui aux victimes d'infractions a été accentuée, en particulierpar un mouvement ― victims' mouvement ―, qui a inauguré un nouveau temps dans lajustice pénale des systèmes juridiques du monde entier. A part la fonction de contrôler lecrime et de punir le délinquant, le système de justice pénale joue également un rôle dans laréhabilitation des victimes.Malgré la réalisation de plusieurs recherches criminologiques sur ce sujet, les effets que lesystème de la justice pénale et les centres d'aides aux victimes ont sur le bien-être desvictimes d'infractions est encore incertain.Ainsi cette étude cherche à mieux comprendre le processus de réhabilitation des victimesd'infraction, les conséquences de leur participation dans le système de justice pénale ainsique la portée de l'appui des centres d'aide. De plus, l'étude vise à découvrir si l'existenced'une loi d'aide aux victimes, particulièrement la Loi d'Aide aux Victimes d'InfractionsLAVI, est susceptible de changer le traitement que la victime reçoit dans le système de lajustice pénale. Pour cela, elle a été conduite dans deux pays - la Suisse et le Brésil - où lesconséquences du mouvement des victimes sur le système de la justice pénale a eu undéveloppement différent; il en va de même pour la participation de la victime dans laprocédure pénale et pour l'appui offert par l'Etat.Cette étude utilise la méthode qualitative qui est la plus efficace pour le recueild'informations sensibles. La plus importante source des données sont les interviews avec lesvictimes. L'observation des audiences et l'analyse de documents ont été utilisés en tant quesources d'information complementáire.Les résultats de cette recherche montrent que les victimes qui ont porté plainte et qui ontreçu l'appui des centres d'aides ne sont pas mieux rétablies que celles qui n'ont rien fait. C'estainsi que nous avons conclu que les services offerts n'ont aucune influence dans ce processus.Cependant, considérant que notre échantillon n'est pas représentatif, il n'est pas possible degénéraliser nos résultats. Néanmoins, ceux-ci peuvent éclairer les praticiens ou les futursdécideurs politiques de la justice pénale, suggérant ce qui peut fonctionner pour lerétablissement des victimes d'infraction, aussi bien que suggérer d'autres études.

Chronic illness, life style and emotional health in adolescence: results of a cross-sectional survey on the health of 15-20-year-olds in Switzerland.

The objective was to evaluate the prevalence of chronic conditions (CC) in adolescents in Switzerland; to describe their behaviour (leisure, sexuality, risk taking behaviour) and to compare them to those in adolescents who do not have CC in order to evaluate the impact of those conditions on their well-being. The data were obtained from the Swiss Multicentre Adolescent Survey on Health, targeting a sample of 9268 in-school adolescents aged 15 to 20 years, who answered a self-administered questionnaire. Some 11.4% of girls and 9.6% of boys declared themselves carriers of a CC. Of girls suffering from a CC, 25% (versus 13% of non carriers; P=0.007) and 38% of boys (versus 25%; P=0.002) proclaimed not to wear a seatbelt whilst driving. Of CC girls, 6.3% (versus 2.7%; P=0.000) reported within the last 12 months to have driven whilst drunk. Of the girls, 43% (versus 36%; P=0.004) and 47% (versus 39%; P=0.001) were cigarette smokers. Over 32% of boys (versus 27%; P=0.02) reported having ever used cannabis and 17% of girls (versus 13%; P=0.013) and 43% of boys (versus 36%; P=0.002) admitted drinking alcohol. The burden of their illness had important psychological consequences: 7.7% of girls (versus 3.4%; P=0.000) and 4.9% of boys (versus 2.0%; P=0.000) had attempted suicide during the previous 12 months. CONCLUSION: experimental behaviours are not rarer in adolescents with a chronic condition and might be explained by a need to test their limits both in terms of consumption and behaviour. Prevention and specific attention from the health caring team is necessary.

Voluntary Explicit versus Involuntary Conceptual Memory Are Associated with Dissociable fMRI Responses in Hippocampus, Amygdala, and Parietal Cortex for Emotional and Neutral Word Pairs.

Although functional neuroimaging studies have supported the distinction between explicit and implicit forms of memory, few have matched explicit and implicit tests closely, and most of these tested perceptual rather than conceptual implicit memory. We compared event-related fMRI responses during an intentional test, in which a group of participants used a cue word to recall its associate from a prior study phase, with those in an incidental test, in which a different group of participants used the same cue to produce the first associate that came to mind. Both semantic relative to phonemic processing at study, and emotional relative to neutral word pairs, increased target completions in the intentional test, but not in the incidental test, suggesting that behavioral performance in the incidental test was not contaminated by voluntary explicit retrieval. We isolated the neural correlates of successful retrieval by contrasting fMRI responses to studied versus unstudied cues for which the equivalent "target" associate was produced. By comparing the difference in this repetition-related contrast across the intentional and incidental tests, we could identify the correlates of voluntary explicit retrieval. This contrast revealed increased bilateral hippocampal responses in the intentional test, but decreased hippocampal responses in the incidental test. A similar pattern in the bilateral amygdale was further modulated by the emotionality of the word pairs, although surprisingly only in the incidental test. Parietal regions, however, showed increased repetition-related responses in both tests. These results suggest that the neural correlates of successful voluntary explicit memory differ in directionality, even if not in location, from the neural correlates of successful involuntary implicit (or explicit) memory, even when the incidental test taps conceptual processes.

Cohesion, satisfaction with family bonds, and emotional well-being in families with adolescents

The present paper investigated whether higher cohesion and satisfaction with family bonds were associated with the daily experience of emotional well-being in varying social circumstances. Using a sample of school-age adolescents (N = 95) and both their parents, data were gathered daily over 1 week using a diary approach in addition to self-report instruments. Multilevel analyses revealed higher cohesion to be associated with well-being in fathers and adolescents, but not in mothers. Parents also reported higher well-being when with friends or colleagues than when alone. Moreover, fathers who scored higher on cohesion reported higher well-being when with family members than when alone, whereas adolescents who scored higher on satisfaction with bonds reported lower well-being when with peers or siblings than when alone.
