The specificity of the familial aggregation of early-onset bipolar disorder: A controlled 10-year follow-up study of offspring of parents with mood disorders.

BACKGROUND: Two major sources of heterogeneity of mood disorders that have been demonstrated in clinical, family and genetic studies are the mood disorder subtype (i.e. bipolar (BPD) and major depressive disorder (MDD)) and age of onset of mood episodes. Using a prospective high-risk study design, our aims were to test the specificity of the parent-child transmission of BPD and MDD and to establish the risk of psychopathology in offspring in function of the age of onset of the parental disorder. METHODS: Clinical information was collected on 208 probands (n=81 with BPD, n=64 with MDD, n=63 medical controls) as well as their 202 spouses and 372 children aged 6-17 years at study entry. Parents and children were directly interviewed every 3 years (mean duration of follow-up=10.6 years). Parental age of onset was dichotomized at age 21. RESULTS: Offspring of parents with early onset BPD entailed a higher risk of BPD HR=7.9(1.8-34.6) and substance use disorders HR=5.0(1.1-21.9) than those with later onset and controls. Depressive disorders were not significantly increased in offspring regardless of parental mood disorder subtype or age of onset. LIMITATIONS: Limited sample size, age of onset in probands was obtained retrospectively, age of onset in co-parents was not adequately documented, and a quarter of the children had no direct interview. CONCLUSIONS: Our results provide support for the independence of familial aggregation of BPD from MDD and the heterogeneity of BPD based on patterns of onset. Future studies should further investigate correlates of early versus later onset BPD.

La surveillance bancaire belge de 1935 façonnée sur le modèle suisse: un discret transfert de politique publique?

Suite aux graves crises bancaires et financières qui ont secoué la plupart de sociétés occidentales au début des années 1930, on assiste à un foisonnement de réglementations publiques sur les activités bancaires. Parmi les très nombreux pays qui mettent en place des législations bancaires, l'on compte notamment la Suisse et la Belgique. Plus précisément, la loi fédérale suisse sur les banques de novembre 1934 précède de quelques mois l'arrêté royal belge no 185 de juillet 1935. Alors que le contexte historique et l'élaboration respective de chacune de ces réglementations ont déjà fait l'objet de plusieurs analyses, la comparaison et la question des éventuels liens entre ces deux régimes de surveillance bancaire très proches sont encore largement inexplorées. Une analyse détaillée du processus d'élaboration de la réglementation bancaire belge révèle que la loi suisse a joué un rôle de modèle mis en avant en premier chef par les représentants du monde bancaire. Cette influence helvétique a contribué à façonner la régulation bancaire dans une perspective libérale ; elle répondait ainsi à deux besoins essentiels: limiter l'interventionnisme étatique au minimum, et court-circuiter le pouvoir de la banque centrale. Cette parenté de naissance entre les deux lois bancaires trouve son pendant dans les activités clés deux organismes de surveillance créés pour l'occasion, la Commission fédérale des banques à Berne et la Commission bancaire à Bruxelles. Disposant toutes deux de moyens d'actions limités, ces deux instances ont connu des parcours analogues au cours de leurs premières années d'activité.

The Swiss cohort study on substance use risk factors : findings of two waves

Aim: To summarize published findings in peer-reviewed journals of the first two waves of the Swiss Cohort Study on Substance Use Risk Factors (C-SURF), a longitudinal study assessing risk and protective factors of 5,987 young men during the phase of emerging adulthood (20 years at baseline, followed-up 15 months later). Methods: Included were 33 studies published until November 2014 focusing on substance use. Results: Substance use in early adulthood is a prevalent and stable behavior. The 12-month prevalence of nonmedical use of prescription drugs (10.6%) lies between that of cannabis (36.4%) and other illicit drugs such as ecstasy (3.7%) and cocaine (3.2%). Although peer pressure in the form of misconduct is associated with increased substance use, other aspects such as peer involvement in social activities may have beneficial effects. Regular sport activities are associated with reduced substance use, with the exception of alcohol use. Young men are susceptible to structural conditions such as the price of alcohol beverages or the density of on-premise alcohol outlets. Particularly alcohol use in public settings such as bars, discos or in parks (compared with private settings such as the home) is associated with alcohol-related harm, including injuries or violence. Being a single parent versus nuclear family has no effect on alcohol use, but active parenting does. Besides parenting, religiousness is an important protective factor for both legal and illegal substance use. Merely informing young men about the risks of substance use may not be an effective preventive measure. At-risk users of licit and illicit substances are more health literate, e. g., for example, they seek out more information on the internet than non-at-risk-users or abstainers. Discussion: There are a number of risk and protective substance use factors, but their associations with substance use do not necessarily agree with those found outside Europe. In the United States, for example, heavy alcohol use in this age group commonly takes place in private settings, whereas in Switzerland it more often takes place in public settings. Other behaviors, such as the nonmedical use of prescription drugs, appear to be similar to those found overseas, which may show the need for targeted preventive actions. C-SURF findings point to the necessity of establishing European studies to identify factors for designing specific preventive actions.

Les inscripcions de la plaça de la Vila de Madrid

Les conclusions que de l’estudi epigràfic se'n poden treure són coincidents amb les que ens aporten les dades de les excavacions arqueològiques. En primer lloc, podem comprovar una utilització de l’àrea com a espai funerari des de l’inici de la colònia de Barcino, amb una continuïtat i, a vegades, superposició de tombes, que arriba fins a ben entrat el segle III dC. Lògicament, la fase que se'ns mostra més potent és la més recent, que arrenca de les darreries del segle II dC per entrar en el III. Tret dels testimonis inicials, que ens fan conèixer fins i tot magistrats de la ciutat, el gruix dels documents correspon a monuments funeraris de les classes menys privilegiades, lliberts i esclaus que, de vegades, ens manifesten una entranyable vessant humana d’afectuoses relacions, en què sovintegen els diminutius. A vegades, l’estatus dels personatges és obertament declarat; en d’altres el deduïm dels termes de parentiu amb una onomàstica que acostuma a ser també ben transparent.

Stable eusociality via maternal manipulation when resistance is costless.

In many eusocial species, queens use pheromones to influence offspring to express worker phenotypes. Although evidence suggests that queen pheromones are honest signals of the queen's reproductive health, here I show that queen's honest signalling can result from ancestral maternal manipulation. I develop a mathematical model to study the coevolution of maternal manipulation, offspring resistance to manipulation and maternal resource allocation. I assume that (i) maternal manipulation causes offspring to be workers against offspring's interests; (ii) offspring can resist at no direct cost, as is thought to be the case with pheromonal manipulation; and (iii) the mother chooses how much resource to allocate to fertility and maternal care. In the coevolution of these traits, I find that maternal care decreases, thereby increasing the benefit that offspring obtain from help, which in the long run eliminates selection for resistance. Consequently, ancestral maternal manipulation yields stable eusociality despite costless resistance. Additionally, ancestral manipulation in the long run becomes honest signalling that induces offspring to help. These results indicate that both eusociality and its commonly associated queen honest signalling can be likely to originate from ancestral manipulation.

Conclusions and future directions for sports events management scholarship

The book adopts a unique stakeholder perspective, structured around the groups and individuals who have an interest in and co-create sports events, including organising committees, promoters, sport organisations, spectators, community groups, sponsors, host governments, the media and NGOs. Each chapter addresses a specific stakeholder, defines that stakeholder and its relationships with sports events, describes the managerial requirements for a successful event, assesses current research and directions for future research, and outlines the normative dimensions of stakeholder engagement (such as sustainability and legacy)

The difference of disease perception by juvenile idiopathic arthritis patients and their parents : analysis of the JAMAR questionnaire.

BACKGROUND: The JAMAR (Juvenile Arthritis Multidimensional Assessment Report) has been developed to evaluate the perception of the patient and his parents on different items: well-being, pain, functional status, quality of life, disease activity, disease course, side effects of medication, therapeutic compliance and satisfaction with illness outcome. Our aim was to compare disease's perception by JIA patients and their parents. METHODS: We included into the study 100 consecutive patients over 7 years of age. We asked both parent and child to complete the JAMAR questionnaire. For each patient we recorded demographic and disease related data. We examined the level of disagreement between children and parents for the quantitative items of the JAMAR: VAS Pain, VAS Disease Activity, VAS Well Being, Juvenile Arthritis Functional Score, HRQoL. Then we looked for a relation between discordance-rate and demographic and clinical variables. RESULTS: Children and parents' median scores for all five items were similar. Individual dyads agreement was low, with a large amount of pairs (80) discordant for at least one item. We found higher MD VAS and JADAS in more discordant dyads, suggesting that when the disease is more active discordance between child and parent increase. CONCLUSION: The JAMAR questionnaire is an important tool that helps clinicians to detect divergent child and parent's disease perceptions. It is essential that both patients and parents fill the JAMAR questionnaire for a complete clinical and psychosocial evaluation.

The Strengths and Difficulties Questionnaire (SDQ-Fin) among Finnish children and adolescents

Objective: The psychometric properties of The Strengths and Difficulties Questionnaire (SDQ-Fin), a Finnish version of a brief screening instrument were studied. Emotional and behavioural problems of 7- to 15-year-olds measured by the SDQ were reported, as well as the occurrence of self-reported eating disturbance symptoms and alcohol use among adolescents. Methods and samples: The cross-sectional school survey included 25 items of the SDQ-Fin, items about eating disturbance, alchol use and child psychiatric help-seeking. The study consists of three community samples: 1. The SDQ-Fin parent (n = 703) and teacher (n = 376) versions of 7 – 12 –year-olds, and self-report versions (n = 528) of 11 – 16 years-olds were obtained, and 2. the parent (n = 81) and self-report versions of 15-16 –year olds (n = 129) were obtained in Laitila and Pyhäranta. 3. The self-report versions of 13 – 16 – year-olds (n = 1458) in Salo and Rovaniemi were obtained. Results: The psychometric properties of the SDQ-Fin were for the most part comparable with the other European SDQ research results. The internal consistency (Cronbach’s alpha = 0.71 in all informants’ reports) and inter-rater reliability (between the pairs of reports r = 0.38 - 0.44) were adequate. The concurrent validity (r = 0.75 between the SDQ and the CBCL total scores; r = 0.71 between the SDQ and the YSR total scores) was sufficient. Factor analysis of the SDQ self-report generally confirmed the postulated structure for girls and boys, except for the conduct problems scale of boys, which was fused with emotional symptoms and with hyperactivity. The response rates, means and cut-off points of the SDQ self-report scores were similar to those found, e.g. in Norway and in Britain. A high level of psychological problems, especially emotional and conduct problems and hyperactivity-inattention, were associated with high level of eating disturbance symptoms and alcohol use. Conclusion: The results showed that the psychometric properties of the SDQ-Fin are adequate and provide additional confirmation of the usefulness of the SDQ-Fin for, e.g. screening, epidemiological research and clinical purposes.

In Vivo Profiling and Distribution of Known and Novel Phase I and Phase II Metabolites of Efavirenz in Plasma, Urine, and Cerebrospinal Fluid.

Efavirenz (EFV) is principally metabolized by CYP2B6 to 8-hydroxy-efavirenz (8OH-EFV) and to a lesser extent by CYP2A6 to 7-hydroxy-efavirenz (7OH-EFV). So far, most metabolite profile analyses have been restricted to 8OH-EFV, 7OH-EFV, and EFV-N-glucuronide, even though these metabolites represent a minor percentage of EFV metabolites present in vivo. We have performed a quantitative phase I and II metabolite profile analysis by tandem mass spectrometry of plasma, cerebrospinal fluid (CSF), and urine samples in 71 human immunodeficiency virus patients taking efavirenz, prior to and after enzymatic (glucuronidase and sulfatase) hydrolysis. We have shown that phase II metabolites constitute the major part of the known circulating efavirenz species in humans. The 8OH-EFV-glucuronide (gln) and 8OH-EFV-sulfate (identified for the first time) in humans were found to be 64- and 7-fold higher than the parent 8OH-EFV, respectively. In individuals (n = 67) genotyped for CYP2B6, 2A6, and CYP3A metabolic pathways, 8OH-EFV/EFV ratios in plasma were an index of CYP2B6 phenotypic activity (P < 0.0001), which was also reflected by phase II metabolites 8OH-EFV-glucuronide/EFV and 8OH-EFV-sulfate/EFV ratios. Neither EFV nor 8OH-EFV, nor any other considered metabolites in plasma were associated with an increased risk of central nervous system (CNS) toxicity. In CSF, 8OH-EFV levels were not influenced by CYP2B6 genotypes and did not predict CNS toxicity. The phase II metabolites 8OH-EFV-gln, 8OH-EFV-sulfate, and 7OH-EFV-gln were present in CSF at 2- to 9-fold higher concentrations than 8OH-EFV. The potential contribution of known and previously unreported EFV metabolites in CSF to the neuropsychological effects of efavirenz needs to be further examined in larger cohort studies.

Hospitalisation du proche : fatigue et coping du proche aidant à l'occasion de cette transition

Le processus de vieillissement entraîne une augmentation et une complexification des besoins de soins. Or, la proportion de personnes vieillissantes dans le monde et en Suisse s'accroit. Les professionnels de la santé ne disposent pas des moyens économiques et humains pour couvrir l'ensemble des besoins de soins. Les proches aidants contribuent de manière importante à la couverture des besoins. Cette contribution devient un élément central de la politique du maintien à domicile. Cependant, l'engagement à long terme des proches aidants auprès de leur parent peut influencer négativement leur état de santé. Pour une même classe d'âge, la population des proches aidants déclare un niveau de fatigue plus élevée que le reste de la population. Dans ce contexte, la fatigue est définie comme le résultat de l'ambivalence entre la demande en soins et les ressources dont dispose le proche aidant. L'hospitalisation du parent, qu'elle soit ou non liée à la fatigue, constitue un moment de crise pour le proche aidant. Face à cette crise, l'aidant mettra en oeuvre des stratégies de coping telles que conceptualisées dans la théorie transactionnelle du stress. Dans le cadre de la théorique intermédiaire de la transition de Meleis, le coping est un indicateur de processus de la transition qui doit permettre d'appréhender la transition vécue par l'aidant à l'occasion de l'hospitalisation du parent. Avec un devis corrélationnel descriptif, cette étude décrit les caractéristiques de l'échantillon de proches aidants, et du rôle qu'ils assument. Elle décrit le degré de fatigue et les styles de coping utilisés, et explore la relation entre la fatigue et le coping du proche aidant à l'occasion de l'hospitalisation du parent. Deux questionnaires auto-administrés ont été complétés par 33 participants. Cette étude a permis de dégager les résultats suivants : le score moyen de fatigue dans cet échantillon indique une fatigue légère selon la classification établie par Piper. Les participants mettent en avant l'influence du rôle d'aidant sur leur fatigue, ainsi que l'influence de leur propre santé et des contraintes économicoprofessionnelles. Le score moyen de fatigue varie en fonction de la nature de l'aide fournie. Il est significativement plus élevé lorsque le proche aidant soutient son parent dans les activités de la vie quotidienne (AVQ). Le style de coping mobilisé préférentiellement dans cet échantillon est le coping centré sur le problème, suivi du coping centré sur la recherche du soutien social, et enfin le coping centré sur l'émotion. Les aidants soutenant leur proche dans les AVQ mobilisent plus le coping centré sur l'émotion que ceux qui n'offrent pas ce type d'aide. Les principales sources de stress nommées par les participants sont l'état de santé du parent, son hospitalisation, et la rencontre avec le système de santé. Dans cet échantillon, nous n'avons pas observé de corrélation entre le degré de fatigue et les trois styles de coping. Des limites liées à la petite taille de l'échantillon amènent à la prudence quant à la généralisation des résultats de cette étude.

Pediatric advance care planning from the perspective of health care professionals: a qualitative interview study.

BACKGROUND: Pediatric advance care planning differs from the adult setting in several aspects, including patients' diagnoses, minor age, and questionable capacity to consent. So far, research has largely neglected the professionals' perspective. AIM: We aimed to investigate the attitudes and needs of health care professionals with regard to pediatric advance care planning. DESIGN: This is a qualitative interview study with experts in pediatric end-of-life care. A qualitative content analysis was performed. SETTING/PARTICIPANTS: We conducted 17 semi-structured interviews with health care professionals caring for severely ill children/adolescents, from different professions, care settings, and institutions. RESULTS: Perceived problems with pediatric advance care planning relate to professionals' discomfort and uncertainty regarding end-of-life decisions and advance directives. Conflicts may arise between physicians and non-medical care providers because both avoid taking responsibility for treatment limitations according to a minor's advance directive. Nevertheless, pediatric advance care planning is perceived as helpful by providing an action plan for everyone and ensuring that patient/parent wishes are respected. Important requirements for pediatric advance care planning were identified as follows: repeated discussions and shared decision-making with the family, a qualified facilitator who ensures continuity throughout the whole process, multi-professional conferences, as well as professional education on advance care planning. CONCLUSION: Despite a perceived need for pediatric advance care planning, several barriers to its implementation were identified. The results remain to be verified in a larger cohort of health care professionals. Future research should focus on developing and testing strategies for overcoming the existing barriers.

Identification of new transformation products during enzymatic treatment of tetracycline and erythromycin antibiotics at laboratory scale by an on-line turbulent flow liquid-chromatography coupled to a high resolution mass spectrometer LTQ-Orbitrap

This work describes the formation of transformation products (TPs) by the enzymatic degradation at laboratory scale of two highly consumed antibiotics: tetracycline (Tc) and erythromycin (ERY). The analysis of the samples was carried out by a fast and simple method based on the novel configuration of the on-line turbulent flow system coupled to a hybrid linear ion trap – high resolution mass spectrometer. The method was optimized and validated for the complete analysis of ERY, Tc and their transformation products within 10 min without any other sample manipulation. Furthermore, the applicability of the on-line procedure was evaluated for 25 additional antibiotics, covering a wide range of chemical classes in different environmental waters with satisfactory quality parameters. Degradation rates obtained for Tc by laccase enzyme and ERY by EreB esterase enzyme without the presence of mediators were ∼78% and ∼50%, respectively. Concerning the identification of TPs, three suspected compounds for Tc and five of ERY have been proposed. In the case of Tc, the tentative molecular formulas with errors mass within 2 ppm have been based on the hypothesis of dehydroxylation, (bi)demethylation and oxidation of the rings A and C as major reactions. In contrast, the major TP detected for ERY has been identified as the “dehydration ERY-A”, with the same molecular formula of its parent compound. In addition, the evaluation of the antibiotic activity of the samples along the enzymatic treatments showed a decrease around 100% in both cases

Functional impact of genetic variation on gene expression

Numerous links between genetic variants and phenotypes are known and genome-wide association studies dramatically increased the number of genetic variants associated with traits during the last decade. However, how changes in the DNA perturb the molecular mechanisms and impact on the phenotype of an organism remains elusive. Studies suggest that many traitassociated variants are in the non-coding region of the genome and probably act through regulation of gene expression. During my thesis I investigated how genetic variants affect gene expression through gene regulatory mechanisms. The first chapter was a collaborative project with a pharmaceutical company, where we investigated genome-wide copy number variation (CNVs) among Cynomolgus monkeys (Macaca fascicularis) used in pharmaceutical studies, and associated them to changes in gene expression. We found substantial copy number variation and identified CNVs linked to tissue-specific expression changes of proximal genes. The second and third chapters focus on genetic variation in humans and its effects on gene regulatory mechanisms and gene expression. The second chapter studies two human trios, where the allelic effects of genetic variation on genome-wide gene expression, protein-DNA binding and chromatin modifications were investigated. We found abundant allele specific activity across all measured molecular phenotypes and show extended coordinated behavior among them. In the third chapter, we investigated the impact of genetic variation on these phenotypes in 47 unrelated individuals. We found that chromatin phenotypes are organized into local variable modules, often linked to genetic variation and gene expression. Our results suggest that chromatin variation emerges as a result of perturbations of cis-regulatory elements by genetic variants, leading to gene expression changes. The work of this thesis provides novel insights into how genetic variation impacts gene expression by perturbing regulatory mechanisms. -- De nombreux liens entre variations génétiques et phénotypes sont connus. Les études d'association pangénomique ont considérablement permis d'augmenter le nombre de variations génétiques associées à des phénotypes au cours de la dernière décennie. Cependant, comprendre comment ces changements perturbent les mécanismes moléculaires et affectent le phénotype d'un organisme nous échappe encore. Des études suggèrent que de nombreuses variations, associées à des phénotypes, sont situées dans les régions non codantes du génome et sont susceptibles d'agir en modifiant la régulation d'expression des gènes. Au cours de ma thèse, j'ai étudié comment les variations génétiques affectent les niveaux d'expression des gènes en perturbant les mécanismes de régulation de leur expression. Le travail présenté dans le premier chapitre est un projet en collaboration avec une société pharmaceutique. Nous avons étudié les variations en nombre de copies (CNV) présentes chez le macaque crabier (Macaca fascicularis) qui est utilisé dans les études pharmaceutiques, et nous les avons associées avec des changements d'expression des gènes. Nous avons découvert qu'il existe une variabilité substantielle du nombre de copies et nous avons identifié des CNVs liées aux changements d'expression des gènes situés dans leur voisinage. Ces associations sont présentes ou absentes de manière spécifique dans certains tissus. Les deuxième et troisième chapitres se concentrent sur les variations génétiques dans les populations humaines et leurs effets sur les mécanismes de régulation des gènes et leur expression. Le premier se penche sur deux trios humains, père, mère, enfant, au sein duquel nous avons étudié les effets alléliques des variations génétiques sur l'expression des gènes, les liaisons protéine-ADN et les modifications de la chromatine. Nous avons découvert que l'activité spécifique des allèles est abondante abonde dans tous ces phénotypes moléculaires et nous avons démontré que ces derniers ont un comportement coordonné entre eux. Dans le second, nous avons examiné l'impact des variations génétiques de ces phénotypes moléculaires chez 47 individus, sans lien de parenté. Nous avons observé que les phénotypes de la chromatine sont organisés en modules locaux, qui sont liés aux variations génétiques et à l'expression des gènes. Nos résultats suggèrent que la variabilité de la chromatine est due à des variations génétiques qui perturbent des éléments cis-régulateurs, et peut conduire à des changements dans l'expression des gènes. Le travail présenté dans cette thèse fournit de nouvelles pistes pour comprendre l'impact des différentes variations génétiques sur l'expression des gènes à travers les mécanismes de régulation.
