Abstract
Cardiotocography (CTG) is currently the most often used technique for detection of fetal distress. Unfortunately, CTG has a poor specificity. Recent studies suggest that, in addition to CTG, information on fetal distress can be obtained from analysis of fetal heart rate variability (HRV). However, uterine contractions can strongly influence fetal HRV. The aim of this study is therefore to investigate whether HRV analysis for detection of fetal distress can be improved by distinguishing contractions from rest periods. Our results from feature selection indicate that HRV features calculated separately during contractions or during rest periods are more informative on fetal distress than HRV features that are calculated over the entire fetal heart rate. Furthermore, classification performance improved from a geometric mean of 69.0% to 79.6% when including the contraction-dependent HRV features, in addition to HRV features calculated over the entire fetal heart rate.

Abstract
OBJECTIVE This paper explores the use of pharmacoeconomic methods of valuation to health impacts resulting from exposure to poor air quality. In using such methods, interventions that reduce exposure to poor air quality can be directly compared, in terms of value for money (or cost-effectiveness), with competing demands for finite resources, including other public health interventions. DESIGN Using results estimated as part of a health impact assessment regarding a West Yorkshire Low Emission Zone strategy, this paper quantifies cost-saving and health-improving implications of transport policy through its impact on air quality. DATA SOURCE Estimates of health-related quality of life and the National Health Service (NHS)/Personal Social Services (PSS) costs for identified health events were based on data from Leeds and Bradford using peer-reviewed publications or Office for National Statistics releases. POPULATION Inhabitants of the area within the outer ring roads of Leeds and Bradford. MAIN OUTCOMES MEASURES NHS and PSS costs and quality-adjusted life years (QALYs). RESULTS Averting an all-cause mortality death generates 8.4 QALYs. Each coronary event avoided saves £28 000 in NHS/PSS costs and generates 1.1 QALYs. For every fewer case of childhood asthma, there will be NHS/PSS cost saving of £3000 and a health benefit of 0.9 QALYs. A single term, low birthweight birth avoided saves £2000 in NHS/PSS costs. Preventing a preterm birth saves £24 000 in NHS/PSS costs and generates 1.3 QALYs. A scenario modelled in the West Yorkshire Low Emission Zone Feasibility Study, where pre-EURO 4 buses and HGVs are upgraded to EURO 6 by 2016 generates an annual benefit of £2.08 million and a one-off benefit of £3.3 million compared with a net present value cost of implementation of £6.3 million. CONCLUSIONS Interventions to improve air quality and health should be evaluated and where improvement of population health is the primary objective, cost-effectiveness analysis using a NHS/PSS costs and QALYs framework is an appropriate methodology.

Abstract
Suicide is a major public health issue, and a critical step in its prevention is a psychiatric assessment of individuals following suicide attempts (NICE 2008). In cases where patients attempt suicide through substance overdose, the central nervous system and consciousness are altered in significant ways. This is problematic, given that patients must have recovered sufficient cognitive capacity if a psychiatric assessment is to yield a meaningful and suitable care plan that the patient will recall and follow (Lukens 2006). Currently, there is no validated tool to assess whether sufficient cognitive recovery has occurred in such patients to ensure their memory of the assessment. Therefore, our goal was to identify indicators that predict preserved memory of undergoing a psychiatric assessment. We carried out a prospective study with 41 patients recruited from an emergency department. We collected data on cognitive tests (including WAIS coding test), memory self-assessment, plasma benzodiazepine levels, age, gender, and educational level at the time of psychiatric assessment. We then assessed patients’ memory for undergoing a psychiatric interview 24 hours post-assessment, using an episodic memory score. Whereas memory self-assessment did not predict the episodic memory score, age, plasma benzodiazepine level, and cognitive test scores significantly influenced it, predicting 70% of memory score variation. Among these factors, the WAIS coding test predicted 57% of the memory score variation. To improve clinical practice, it may be useful to assess visual scanning, processing speed, and attentional function prior to psychiatric interview to ensure later patient recall.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
During labor, uterine contractions can cause temporary oxygen deficiency for the fetus. In case of severe and prolonged oxygen deficiency this can lead to asphyxia. The currently used technique for detection of asphyxia, cardiotocography (CTG), suffers from a low specificity. Recent studies suggest that analysis of fetal heart rate variability (HRV) in addition to CTG can provide information on fetal distress. However, interpretation of fetal HRV during labor is difficult due to the influence of uterine contractions on fetal HRV. The aim of this study is therefore to investigate whether HRV features differ during contraction and rest periods, and whether these differences can improve the detection of asphyxia. To this end, a case-control study was performed, using 14 cases with asphyxia that were matched with 14 healthy fetuses. We did not find significant differences for individual HRV features when calculated over the fetal heart rate without separating contractions and rest periods (p > 0.30 for all HRV features). Separating contractions from rest periods did result in a significant difference. In particular the ratio between HRV features calculated during and outside contractions can improve discrimination between fetuses with and without asphyxia (p < 0.04 for three out of four ratio HRV features that were studied in this paper).

Abstract
On sait depuis longtemps que les traitements combinés d’antidépresseurs et de psychothérapies donnent les meilleurs résultats pour soigner les dépressions. L’étude STAR-D avec ses 4 étapes aboutit à 67 % de rémissions, une des dernières étapes associe la psychothérapie. Donc un tiers des patients reste sans amélioration. D’où l’idée d’associer ou de privilégier un traitement psychothérapeutique. Mais lequel, sachant qu’aucune forme de psychothérapie cognitive, interpersonnelle, dynamique ou de soutien n’a montré une réelle supériorité. Deux grandes stratégies psychothérapeutiques sont utilisées dans les dépressions résistantes :– l’évaluation systématique d’un trouble de la personnalité, dont la personnalité état limite, d’un facteur de stress ou d’un événement traumatique, d’une addiction ou d’un trouble anxieux comorbide définit l’étape initiale. Elle se complète de l’évaluation des mécanismes de défense prévalant de la personnalité (cf. code additionnel du DSM-V) ;– des techniques de soin récentes proviennent des thérapies dialectiques pour certaines, des thérapies psychodynamiques pour d’autres.Ces approches prennent en compte l’importance des ruminations, du perfectionnisme, de l’attachement, de la détresse comme facteurs d’aggravation des dépressions. Elles tentent d’améliorer la difficulté qu’ont les patients pour exprimer des émotions, l’analyse d’une hyper-vigilance, les pensées rigides, la peur de s’engager dans des relations mutuelles, des pensées de jalousie et des idées de revanche. Dans la Tavistock Adult Depression Study, on s’intéresse aux enjeux de passivité, de barrière au traitement et de résilience qui jouent un rôle dans la chronicité d’un état dépressif. Parmi les facteurs d’efficacité des stratégies psychothérapeutiques il faut citer l’observance des patients vis-à-vis du dispositif de soins, une séance hebdomadaire avec des durées supérieures à 16 semaines de traitement.

Abstract
L’art-thérapie porte en terre hexagonale, un lourd bagage de fausses notes conceptuelles, d’hégémonies et de clivages cheminant parfois avec une certaine note d’obscurantisme consensuel. Toujours d’actualité, la répétition de cette dynamique souffre d’un manque d’autocritique et d’auto-analyse constructive. Pourtant les dinosaures de l’art-thérapie d’hier empruntent, lorsqu’ils n’ont pas tiré leur révérence, la voie de la sagesse. Ceux d’aujourd’hui s’échinent à tenir des vestiges, voire des temples vides, même lorsqu’ils empruntent la toge de la transmission. Si jusqu’à l’aube des années 1980, l’art-thérapie était encore l’apanage de la psychiatrie et des psychiatres, elle concerne aujourd’hui des praticiens d’origine multiple et s’étend du développement personnel aux champs du somatique, sans pour autant se cristalliser dans une réelle identité professionnelle. À l’instar d’autres spécialités d’antan, elle erre dans une sorte de flou-doux-mou peu et/ou mal étayée sur une recherche clinique à même de fournir des recommandations pour de bonnes pratiques et un corpus de savoir. Pourtant les approches symptomatologiques, psychopathologiques, phénoménologiques, structurales, pictographiques, psychobiographiques et autres, souvent référencées aux arts et/ou à la psychanalyse, produisent légitimement, sous couvert du piège de la séduction esthétique, une jouissance relativement éloignée du terrain. Quant aux organismes, plus ou moins fédératifs, leur prétention en matière « d’accréditation » des professionnels de l’art-thérapie, se révèle là-aussi bien éloignée du réel de la clinique et des expériences d’autres pays européens (Suisse, par exemple). Enfin, les intitulés des formations, initiales comme continues, jouent sur des ambiguïtés de vocabulaires et d’expressions, difficiles à décrypter par les novices. Nous développerons chacun de ces points en proposant quelques médications génériques pour traiter des pathologies endémiques « de la dame art-thérapie ».

Abstract
Few studies have examined the association between childhood maltreatment (CM) and personality disorders (PDs) in adulthood in two different cultural contexts, including sub-Saharan Africa. The aims of this study were to compare the frequency of CM between patients in treatment in France and Togo for a major depressive disorder (MDD), to explore the link between CM and PDs, and to examine the mediating effect of personality dimensions in the pathway from CM to PDs in 150 participants (75 in each country). The 28-item Childhood Trauma Questionnaire, the International Personality Item Pool, and the Personality Diagnostic Questionnaire (PDQ-4+) were used to assess CM, personality dimensions, and PDs respectively. Togolese participants reported sexual and physical abuse (PA) and emotional and physical neglect significantly more frequently than French participants. In Togo, severe PA was associated with schizoid, antisocial, narcissistic, obsessive-compulsive, depressive, and negativist PDs whereas in France, PA was only linked to paranoid PD. In Togo, emotional instability partly mediated the relationship between CM and PDs while in France, no personality dimension appeared to mediate this link. Our results support the hypothesis that CM is more common in low-income countries and suggest that the links between CM and PDs are influenced by social environment.

Abstract
This study investigated changes in heart rate variability (HRV) in elite Nordic-skiers to characterize different types of "fatigue" in 27 men and 30 women surveyed from 2004 to 2008. R-R intervals were recorded at rest during 8 min supine (SU) followed by 7 min standing (ST). HRV parameters analysed were powers of low (LF), high (HF) frequencies, (LF+HF) (ms(2)) and heart rate (HR, bpm). In the 1 063 HRV tests performed, 172 corresponded to a "fatigue" state and the first were considered for analysis. 4 types of "fatigue" (F) were identified: 1. F(HF(-)LF(-))SU_ST for 42 tests: decrease in LFSU (- 46%), HFSU (- 70%), LFST (- 43%), HFST (- 53%) and increase in HRSU (+ 15%), HRST (+ 14%). 2. F(LF(+) SULF(-) ST) for 8 tests: increase in LFSU (+ 190%) decrease in LFST (- 84%) and increase in HRST (+ 21%). 3. F(HF(-) SUHF(+) ST) for 6 tests: decrease in HFSU (- 72%) and increase in HFST (+ 501%). 4. F(HF(+) SU) for only 1 test with an increase in HFSU (+ 2161%) and decrease in HRSU (- 15%). Supine and standing HRV patterns were independently modified by "fatigue". 4 "fatigue"-shifted HRV patterns were statistically sorted according to differently paired changes in the 2 postures. This characterization might be useful for further understanding autonomic rearrangements in different "fatigue" conditions.

Abstract
BACKGROUND In times of fiscal restraint for health structures, apart from the clinical input, it seems important to discuss the economic impact of liaison psychiatry. There are only a few studies on the economic added value provided by a liaison psychiatry team. In addition to this, only a few psychiatric pathologies are coded as they should be, hence we make the assumption of an additional development provided by a specialised team. METHODS Over a short period of 4months, in three departments of the Toulouse University Hospital Centre, the added value to the general pricing system of liaison psychiatry was studied. The population was represented by all the consecutive requests for consultations from patients over 18years old, men and women, hospitalised at that time. These three departments frequently request consultations with the psychiatry liaison team. They set a diagnostic, and if this is associated with a higher Homogeneous Group of Patients (HGP), it provides added value. RESULTS Fifty-two patients benefited from a psychiatric consultation over 4months. The results highlight a development of € 8630.43 for the traumatology department, € 3325.03 for the internal medicine department, and € 513.61 for the haematology department over the study period. The overall development over this period was € 12,469.07. CONCLUSION To our knowledge, this approach is one of the first in France to highlight an economic impact of the intervention of liaison psychiatry in the claiming departments.

Abstract
Urbanization subjects streams to increased nitrogen loads. Therefore studying nitrogen forms at the interface between urban stream and groundwater is important for water resource management. In this study we report results on water δ(18)O and nitrogen forms in subsurface waters of a stream (Yzeron, France). The sites studied were located upstream and downstream of combined sewer overflows (CSO) in a rural area and a periurban area, respectively. Water δ(18)O allowed us to follow the mixing of subsurface water with surface water. Dissolved organic nitrogen and organic carbon of fine sediment increased by 20-30% between rural and periurban subsurface waters in the cold season, under high flow. The highest nitrate levels were observed in rural subsurface waters in the cold season. The lowest nitrate levels were found in periurban subsurface waters in the warm season, under low flow. They corresponded to slow exchange of subsurface waters with channel water. Thus reduced exchange between surface and subsurface waters and organic-matter-rich input seemed to favor nitrate reduction in the downstream, periurban, subsurface waters impacted by CSO.

Abstract
Ataxin 2 binding protein 1 (A2BP1 aka FOX1, RBFOX1) is an RNA binding protein responsible for regulation of pre-mRNA splicing events in a number of critical developmental genes expressed in muscle, heart and neuronal cells [Shibata et al. (2000); Mamm Genome 12:595-601; Jin et al. (2003); EMBO J 22:905-912; Underwood et al. (2005); Mol Cell Biol 25:10005-10016]. Rare copy number abnormalities of A2BP1 have been previously associated with cognitive impairment, attention deficit disorder and autism [Martin et al. (2007); Am J Med Gen Part B 144B:869-876; Elia et al. (2010); Mol Psychiatry 15:637-646.]. Using a 1M Illumina SNP microarray, we identified a 1.3 kb deletion in A2BP1, which was subsequently validated by quantitative PCR. Here we present an in depth case study of an individual with autism and mild developmental hemiparesis in whom the deletion was detected. This study provides further support for the possible role of rare copy number variants in A2BP1 in the development of autism and associated motor asymmetries.

Abstract
The COMPASS Collaboration at CERN has investigated the π- γ → π- π- π+ reaction at center-of-momentum energy below five pion masses, sqrt[s]<5m(π), embedded in the Primakoff reaction of 190 GeV pions impinging on a lead target. Exchange of quasireal photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, t'<0.001 GeV2/c2. Using partial-wave analysis techniques, the scattering intensity of Coulomb production described in terms of chiral dynamics and its dependence on the 3π-invariant mass m(3π)=sqrt[s] were extracted. The absolute cross section was determined in seven bins of sqrt[s] with an overall precision of 20%. At leading order, the result is found to be in good agreement with the prediction of chiral perturbation theory over the whole energy range investigated.

Abstract
In science education, inquiry-based approaches to teaching and learning provide a framework for students to building critical-thinking and problem-solving skills. Teacher professional development has been an ongoing focus for promoting such educational reforms. However, despite a strong consensus regarding best practices for professional development, relatively little systematic research has documented classroom changes consequent to these experiences. This paper reports on the impact of sustained, multiyear professional development in a program that combined neuroscience content and knowledge of the neurobiology of learning with inquiry-based pedagogy on teachers' inquiry-based practices. Classroom observations demonstrated the value of multiyear professional development in solidifying adoption of inquiry-based practices and cultivating progressive yearly growth in the cognitive environment of impacted classrooms.

Abstract
BACKGROUND Many patients develop psychiatric and behavioral disturbances in the course of Alzheimer's disease (AD). Among these disturbances, depressive symptoms are frequent and affect nearly 40% of patients. The natural history and course of such symptoms in AD, and in particular the predictive factors, are little known. We studied the incidence and risk factors for the development of the first depressive symptoms in AD. DESIGN Multicenter prospective study. PARTICIPANTS Three hundred twelve AD patients from the French Network on AD (REAL.FR) without depression and without antidepressant treatment at baseline were followed up and assessed every 6 months for 4 years. During follow-up, all events occurring between two visits were carefully recorded. MEASUREMENTS We used the Neuropsychiatric Inventory (NPI) for comprehensive evaluation of behavioral and psychological symptoms and depressive symptoms in particular. A multivariate analysis was performed using a backward stepwise Cox proportional hazards model. RESULTS The incidence of depressive symptoms was 17.45% person/years, 95%CI (13.88-21.02). Among non-time dependent variables, duration of disease (RR=0.51; 95%CI: 0.30-0.85, p=0.0102) and the number of comorbid conditions (RR=0.45; 95%CI: 0.24-0.83, p=0.0115) were protective factors against the development of depressive symptoms. Agitation/aggression (RR=1.96; 95%CI: 1.19-3.23, p=0.0078) and sleep disturbances (RR=2.65; 95%CI: 1.40-5.00, p=0.0026) were time-dependent variables predictive of depressive symptoms. CONCLUSION Better knowledge of predictive factors of mood disturbances in AD will enable clinicians to set up appropriate management of their patients. As published longitudinal studies are few, further works should be carried out to improve knowledge of the pattern and course of depression and depressive symptoms in AD.

Abstract
BACKGROUND Borderline personality disorder (BPD) accounts for 10% of outpatient psychiatric practice. The risk of suicide attempts is high and the psychosocial impairment significant. Different theoretical streams have suggested psychotherapeutical approaches for BPD. OBJECTIVE to examine the efficacy of psychotherapy for BPD patients on affective symptoms, behavioural outcomes, interpersonal and social functioning, as well as BPD criteria. METHODS We reviewed the medical literature from 1990 to 2008 on Medline by combining the following keywords "borderline personality disorder" and "psychotherapy" (inclusion criteria). We restricted the analysis to "randomised control trial" or "meta analysis". RESULTS Of the 39 abstracts that came out from the search, we selected 17 (44%) after applying the exclusion criteria. According to our review, different types of psychotherapies have shown some efficacy on reducing affective symptoms and BPD criteria, as well as improving behavioural outcomes and psychosocial functioning. Dialectical behavioural therapy presents the best-documented efficacy, notably on reducing self-mutilating and suicidal behaviours (five randomized controlled trials [RCT]). Mentalization based treatment seems to be efficient on the four types of outcomes, but has been the object of only one RCT. Finally, some evidence suggests that Manual Assisted Cognitive Treatment and Systems Training for Emotional Predictability and Problem Solving are the most cost-effective and easiest to be implemented. CONCLUSION According to our review, some evidence supports an efficiency of psychotherapies in the management of several features of BPD. It is likely that, depending on the target symptoms, one type of therapy might be more efficient than another. The acceptability of these long-term treatments is however unknown.
