2q34-qter duplication and 4q34.2-qter deletion in a patient with developmental delay.

The 2q3 duplication and 4q3 deletion syndromes are two conditions with variable phenotypes including Pierre-Robin sequence (PRS), limb anomalies, congenital heart defects (CHD), developmental delays and intellectual disabilities. We describe a patient born to a mother with a balanced t(2; 4) translocation who combines both a 2q34-qter duplication and a 4q34.2-qter deletion through inheritance of the derivative chromosome 4 (der(4)). He showed developmental delay, growth retardation, hearing problems, minor facial and non-facial anomalies, such as bilateral fifth finger shortness and clinodactyly, but no PRS or CHD. The comparison of his features with those of 46 and 65 published cases of 2q3 duplication and 4q3 deletion, respectively, allows us to further restrict the size of the proposed critical intervals for PRS and CHD on chromosome 4.

Perception of damaging effects of smoking, and brief cessation counselling by doctors : a comparison between native Swiss and immigrants

Résumé Une étude prospective ouverte a été menée parmi les patients venant pour la première fois, sans rendez-vous et en urgence, dans une policlinique urbaine (où plus de la moitié des patients sont d'origine étrangère) pour déterminer si les connaissances sur les méfaits du tabac sont identiques chez les immigrés et les Suisses, si le niveau d'intégration influence les connaissances et si les médecins du service donnent des conseils aussi souvent aux fumeurs Suisses qu'aux fumeurs étrangers. 226 fumeurs ont participé à l'étude, 105 Suisses (46.5%) et 121 étrangers (53,5%). 32.2% (95% IC [24.4%; 41.1%]) des migrants et 9.6% [5.3% ; 16.8%] des Suisses ne pouvaient pas mentionner un effet nocif du tabac. Après ajustement pour l'âge, l'analyse multivariée montre que le risque d'ignorer les méfaits du tabac est plus élevé pour les personnes ne maîtrisant pas la langue locale que pour celles la maîtrisant (odds ratio (OR)=7.5 [3.6; 15.8], p<0,001), et est plus élevé pour les hommes que pour les femmes (OR=4.3 [1.9 10.0], p<0.001). Un conseil pour arrêter de fumer a été donné avec une égale fréquence aux immigrants (31.9% [24.2% ; 40.1%]) et aux Suisses (29% [21.0% ; 38.5%]). Les patients ne maîtrisant pas la langue locale n'ont pas reçu moins de conseil que ceux la maîtrisant (0R-1.1 [0.6 ; 2.1], p=0.812). En conclusion, le niveau de connaissances des méfaits du tabac est moins bon chez les hommes immigrés non intégrés ou qui ne maîtrisent pas la langue locale. Un conseil sur l'arrêt du tabac n'est donné qu'à une minorité, mais à égale fréquence à tous les patients du service, quelle que soit leur nationalité. Abstract An open prospective study was conducted among the patients visiting an urban medical policlinic for the first time without an appointment to assess whether the immigrants (who represent more than half of our patients) are aware of the health effects of smoking, whether the level of acculturation influences knowledge, and whether doctors give similar advice to Swiss and foreign smokers. 226 smokers, 105 Swiss (46.5%), and 121 foreign-born (53.5%), participated in the study. 32.2% (95% CI [24.4%; 41.1%]) of migrants and 9.6% [5.3%; 16.8%] of Swiss patients were not aware of negative effects of smoking. After adjustment for age, the multivariate model showed that the estimated odds of "ignorance of health effects of smoking" was higher for people lacking mastery of the local language compared with those mastering it (odds ratio (OR) = 7.5 [3.6; 15.8], p <0.001), and higher for men (OR 4.3 [1.9; 10.0], p <0.001). Advice to stop smoking was given with similar frequency to immigrants (31.9% [24.2%; 40.8%] and Swiss patients (29.0% [21.0%; 38.5%]). Non-integrated patients did not appear to receive less counselling than integrated patients (OR = 1.1 [0.6; 2.1], p 0.812). We conclude that the level of knowledge among male immigrants not integrated or unable to speak the local language is lower than among integrated foreign-born and Swiss patients. Smoking cessation counselling by a doctor was only given to a minority of patients, but such counselling seemed irrespective of nationality.

A NOVEL MUTATION IN BCS1L IN A PATIENT WITH AN ISOLATED MITOCHONDRIAL COMPLEX III DEFICIENCY

Background: Isolated complex III deficiencies are caused by mutations in the mitochondrial CytB gene, in the BCS1L gene coding for a CIII assembly factor and in the UQCRQ gene that codes for the ubiquinone binding protein of complex III. Objective: Description of clinical features, mitochondrial function and molecular genetic analysis in a patient with an isolated complex III deficiency. Patient: A 17 year old boy, born to consanguineous parents who presented with hypoglycemia, glycosuria, deafness, growth retardation, Fanconi Syndrome and severe lactic acidosis in the neonatal period. Methods: Activities and assembly of OXPHOS complexes were investigated spectrophotometrically and by BN-PAGE. mt-DNAwas screened for deletions. Cytochrome b (CytB) and the BCS1L gene were sequenced. Results: Isolated complex III deficiency was detected in the patient's skeletal muscle. Using BN-PAGE blotting a complex III of lower molecular weight was detected. Staining the 2D reveals a missing subunit. No mutation was detected in the mitochondrial CytB gene. Sequence analysis of BCS1L revealed a novel homozygous point mutation p.M48V. Conclusion: The patients decreased complex III activity is most likely caused by incomplete assembly of complex III due to the homozygous p. M48V mutation in the BCS1L gene.

Adverse life events among community-dwelling persons aged 65-70 years: gender differences in occurrence and perceived psychological consequences.

OBJECTIVES: To describe the occurrence of selected adverse life events in young-old men and women, as well as their perceived psychological consequences. METHODS: In 2005, 1,422 participants in the Lausanne Cohort 65+ study, born in 1934-1938, self-reported whether they experienced any of 26 life events during the preceding year. Most participants (N = 1,309, 92%) completed the geriatric adverse life events scale during a face-to-face interview, by rating the level of stress associated with each event, as well as its impact on their psychological well-being. RESULTS: Overall, 72% of the participants experienced at least one of the 26 events in the preceding year (range 1-9). Disease affecting the respondent (N = 525) or a close relative (N = 276) was most frequent, as well as the death of a friend or non-close relative (N = 274). Women indicated a higher frequency of events (mean 2.1 vs. 1.7 events, P < 0.001), as well as a higher level of stress and a stronger negative impact on well-being than men. In multivariate analyses adjusting for self-rated health, depressive symptoms and comorbidity, female gender remained significantly associated with the level of stress and negative impact on psychological well-being. CONCLUSION: This exploratory study shows that several types of adverse life events frequently occur at age 65-70, with gender differences both in the frequency of reporting and consequences of these events. However, information on this topic is limited and studies based on different populations and designs are needed to better understand the impact of such events.

Prenatal ultrasonographic detection of gastrointestinal obstruction: results from 18 European congenital anomaly registries.

OBJECTIVES: We evaluated the prenatal detection of gastrointestinal obstruction (GIO, including atresia, stenosis, absence or fistula) by routine ultrasonographic examination in an unselected population all over Europe. METHODS: Data from 18 congenital malformation registries in 11 European countries were analysed. These multisource registries used the same methodology. All fetuses/neonates with GIO confirmed within 1 week after birth who had prenatal sonography and were born during the study period (1 July 1996 to 31 December 1998) were included. RESULTS: There were 670 793 births in the area covered and 349 fetuses/neonates had GIO. The prenatal detection rate of GIO was 34%; of these 40% were detected < or = 24 weeks of gestation (WG). A total of 31% (60/192) of the isolated GIO were detected prenatally, as were 38% (59/157) of the associated GIO (p=0.26). The detection rate was 25% for esophageal obstruction (31/122), 52% for duodenal obstruction (33/64), 40% for small intestine obstruction (27/68) and 29% for large intestine obstruction (28/95) (p=0.002). The detection rate was higher in countries with a policy of routine obstetric ultrasound. Fifteen percent of pregnancies were terminated (51/349). Eleven of these had chromosomal anomalies, 31 multiple malformations, eight non-chromosomal recognized syndromes, and one isolated GIO. The participating registries reflect the various national policies for termination of pregnancy (TOP), but TOPs after 24 WG (11/51) do not appear to be performed more frequently in countries with a liberal TOP policy. CONCLUSION: This European study shows that the detection rate of GIO depends on the screening policy and on the sonographic detectability of GIO subgroups.

Trajectòries d'èxit de joves immigrants a l'ensenyament superior i al món professional

L’educació dels immigrants és un tema prioritari a les agendes polítiques de molts països de la OCDE. En molts casos, els governs s’han preocupat especialment de la seva integració al món del treball però creix l’interès en els seus resultats al sistema educatiu i en la revisió de les polítiques adreçades a respondre a les seves necessitats educatives i formatives. La majoria d’aquests estudis es situen a l’esfera de l’educació infantil, primària, secundaria i formació professional, per això resulta pràcticament impossible trobar estudis que analitzin el baix percentatge d’accés d’estudiants immigrants extracomunitaris a la universitat (al voltant de 3,3% en el cas de Catalunya); que contribueixin a entendre els factors que configuren les trajectòries d’èxit escolar i d’integració laboral dels estudiants immigrants que accedeixen i completen els estudis universitaris; que puguin donar pautes per desenvolupar polítiques educatives que millorin els resultats d’aprenentatge dels estudiants immigrants; i que puguin servir com a mirall i incentiu per a altres persones immigrants i, perquè no, també del país. Aquest projecte ha estudiat el conjunt d’elements que condicionen l’accés dels joves immigrants als estudis universitaris, i a l’estatus laboral que els hauria de possibilitar la seva formació universitària. L’estudi ha consistit en una metaanàlisi dels documents existents sobre el tema i en la realització de 8 narratives biogràfiques; quatre de persones cursant diferents estudis a les universitats catalanes i quatre que ja s’han incorporat al món del professional. Aquestes narratives venen acompanyades de 8 vídeos que exploren noves maneres de visibilització d’aquesta població i es transformen en una pràctica d’autoria. Aquest material visual pot servir com a recurs educatiu, en la mida que pugui ser un mirall i un incentiu per a altres persones immigrants i del país. Finalment, presenta un seguit de recomanacions per als responsables de les polítiques i dels centres educatius.

Assimilació, integració laboral, domini de l'idioma i segregació residencial

La literatura econòmica sobre immigració i mercat de treball ha analitzat dos grans temes. Un és l’efecte que genera la immigració sobre les condicions laborals (ocupació i salaris) dels nadius. L’altre és l’assimilació dels immigrants en el país d’acollida. Aquest projecte s'emmarca en aquesta segona línia de recerca. L’assimilació s’entén com un procés complex en el que un immigrant s’integra completament en el seu país d’acollida en diferents aspectes interrelacionats: l’estatus socioeconòmic, el progrés salarial, el domini de l’idioma o la segregació residencial, entre d'altres. El nostre projecte es centra en l’anàlisi de l’assimilació dels immigrants que han arribat recentment al nostre mercat de treball. Des d'aquesta perspectiva, s'ha analitzat si com a conseqüència de la transferibilitat limitada del capital humà entre països, es produeix o no una degradació ocupacional inicial que porti associada una quantiosa diferència salarial amb els nadius de similars característiques. De fet, com menys transferible sigui el capital humà d'origen, major serà la degradació ocupacional i la consegüent bretxa salarial inicial. També s'ha analitzat de manera més directa quin paper juga la portabilitat del capital humà a l'hora d'explicar el progrés econòmic dels immigrants. L’evidència obtinguda permet concloure que, a mesura que s'amplia el temps de residència al país de destinació, el capital humà es va adaptant als requeriments del mercat laboral del país hoste, especialment a través de l'experiència en el lloc de treball, però també per aprenentatge del nou idioma o fins i tot realització d'estudis. El capital humà així acumulat permet millorar posicions en l'escala ocupacional i augmentar en paral•lel els ingressos, assimilant-los amb el temps als dels nadius d'iguals característiques. Per últim, l’anàlisi del paper de les xarxes socials dels immigrants mostra un efecte positiu sobre la probabilitat de trobar feina però un pitjor emparellament en el mercat de treball.

The curvature of the conical intersection seam: an approximate second-order analysis

We present a method for analyzing the curvature (second derivatives) of the conical intersection hyperline at an optimized critical point. Our method uses the projected Hessians of the degenerate states after elimination of the two branching space coordinates, and is equivalent to a frequency calculation on a single Born-Oppenheimer potential-energy surface. Based on the projected Hessians, we develop an equation for the energy as a function of a set of curvilinear coordinates where the degeneracy is preserved to second order (i.e., the conical intersection hyperline). The curvature of the potential-energy surface in these coordinates is the curvature of the conical intersection hyperline itself, and thus determines whether one has a minimum or saddle point on the hyperline. The equation used to classify optimized conical intersection points depends in a simple way on the first- and second-order degeneracy splittings calculated at these points. As an example, for fulvene, we show that the two optimized conical intersection points of C2v symmetry are saddle points on the intersection hyperline. Accordingly, there are further intersection points of lower energy, and one of C2 symmetry - presented here for the first time - is found to be the global minimum in the intersection space

Am I my brain or my genitals? A nature-culture controversy in the hermaphrodite debate from the mid-1960s to the late 1990s.

The groundbreaking and prophetic rhetoric of neuroscience has recently highlighted the fetal brain as the most promising organ for understanding why transsexuals feel "trapped in the wrong body", and for predicting whether children born with "ambiguous" genitalia will grow up to feel like a man or a woman.This article proposes a recent history of the cerebralization of intersexuality and of transsexuality as atypical neurodevelopmental conditions. It examines the ways in which the organizational theory of brain sex differentiation developed in the late 1950s in behavioral neuroendocrinology has gained increased prominence in and through controversies over best practice issues in the case management of intersex newborns, and the etiology of transsexuality.It focuses on the American context and on the leading warrior in this battle: Milton Diamond, now a most prominent figure in professional debates about the clinical management of intersexuality, and the intersex person's best friend. Persons with an intersexed or transsexual condition consider, not their gonads, but their brains, their core sense of self, as the primary determinant of sex. (Diamond and Beh 2005, 6-7, note 1)

Programa de condicionament físic inicial

L'objectiu d'aquest programa penitenciari sobre l’activitat física i l’esport ha sorgit de la inquietud que mostra un grup de professionals de la casa per arribar a un major nombre de població interna que gairebé no té informació sobre la cultura esportiva i el coneixement del propi cos. També per la necessitat de fugir d’un model excessivament reduccionista que equipara la pràctica física a la utilització de determinats espais (gimnàs) amb l’única finalitat d’hipertrofiar la musculatura i retre culte al cos (sense atendre altres necessitats més globals). També per consolidar (definitivament) dins les àrees esportives dels centres un model de pràctica física que s’adreci exclusivament a la millora de la salut de la població interna, per fixar hàbits en el seu imaginari que faciliti una manera de posar-se en formareal i realista amb les pròpies limitacions de cadascú... I, per últim, però no menys important, per dotar els professionals dels centres penitenciaris d’una eina útil per a la planificació d’activitats, un recurs més per aprofundir en la millora de la salut a través de la pràctica física.

Sox genes in C. elegans: sox-2 role in postembryonic development

Report for the scientific sojourn carried out at the Columbia University, United States, from 2010 to 2012. Expression of SoxB genes correlates with the commitment of cells to a neural fate; however, the relevance of SoxB proteins in early vertebrate neurogenesis has been difficult to prove genetically due to embryonic lethality and presumed redundant functions. The nematode C. Elegants has only 5 sox genes: sox-2 and sox-3 form the SoxB group while sem-2, sox-4 and egl-13 belong to other Sox groups. Our results show that sox-2 and sem-2 are the sox genes expressed earliest and in a broader manner during embryogenesis, being expressed in several neuronal progenitors. sox-3, sox-4 and egl-13 are expressed in few cells during late embryogenesis, when most neurons are already born. Both sox-2 and sem-2 null mutants are early larval lethal but do not show neuronal specification defects during embryonic development as indicated by quantification of a panneuronal reporter. Potential redundancy or compensatory mechanisms between different sox genes have been ruled out, strongly suggesting that sox genes are not required for specification of embryonically-derived neurons. However, at the first larval stage there are still several blast cells that will give rise to different postembryonic lineages, which generate several neurons amongst other cell types. nterestingly, sox-2 is expressed in many of these progenitor cells. Using mosaic analysis we have so far identified neurons derived from two different postembryonic lineages which fail to be generated in C. elegans sox-2 mutants. These results support the idea that postembryonic progenitor competence is compromised in the absence of sox-2.

Clairvoyance de l'utilité et de la désirabilité sociales dans les situations d'évaluation

Résumé Le concept de clairvoyance normative (Py & Somat, 1991), qui a vu le jour dans la continuité des études sur la norme d'internalité (Beauvois, 1984), traduit la connaissance du caractère normatif ou contre-normatif d'un type de comportements ou d'un type de jugements. Un certain nombre de recherches semble alors attester que la clairvoyance normative participe à l'obtention d'une évaluation positive. Toutefois, ces différentes recherches font toutes fi de l'idée qu'il existerait deux dimensions de la valeur sociale : l'utilité sociale et la désirabilité sociale. La prise en compte de ces deux dimensions, surtout si l'on admet que les normes sociales ne renvoient pas toutes à la même dimension (Beauvois, 1995 ; Dubois & Beauvois, 2005 ; Dubois, 2005), vient alors quelque peu compliquer le modèle liant clairvoyance normative et évaluation positive car elle suggère que la clairvoyance de certaines normes aidera avant tout à être bien évalué sur le plan de l'utilité sociale alors que la clairvoyance d'autres normes participera davantage à être évalué favorablement sur le plan de la désirabilité sociale. Ces réflexions ont été à la base de ce travail de thèse et ont conduit à la réalisation de notre première étude. Les quelques résultats inattendus que nous avons obtenus nous ont cependant incité par la suite à reconsidérer la pertinence de rattacher la notion de clairvoyance à certains types de contenu (internalité, autosuffisance, etc.), ce qui nous a amené à la proposition de deux nouvelles notions : la clairvoyance de l'utilité sociale et la clairvoyance de la désirabilité sociale. C'est dans l'optique de valider cette proposition que deux nouvelles études ont alors été réalisées. Si celles-ci appuient dans leur ensemble l'idée que les clairvoyances de l'utilité et de la désirabilité sociales seraient des indicateurs plus performants d'une évaluation sociale positive que ne le seraient les clairvoyances des normes sociales de jugement, elles n'ont néanmoins pas manqué de soulever de nouvelles questions. Cela nous a ainsi mené, dans un troisième temps, à nous interroger sur ce qui détermine la valeur en jeu dans une situation d'évaluation. Nos trois dernières études ont été construites dans ce dessein et ont participé, en conclusion de ce travail, à étayer l'idée que la clairvoyance de la valeur sociale des jugements ne permettrait l'obtention d'une évaluation positive que si celle-ci va de pair avec une certaine clairvoyance de la valeur sociale des éléments constitutifs de la situation d'interaction. Abstract The concept of normative clearsightedness (Py & Somat, 1991), born in continuity with studies on the norm of internality (Beauvois, 1984), reflects the knowledge of the normative or counter-normative nature of a type of behaviour or a type of judgement. Several researches appear to show that normative clearsightedness helps to obtain a positive evaluation. However, none of these researches takes into account the idea that there might be two dimensions of social value: social utility and social desirability. Considering those two dimensions, especially if we accept that not all social norms refer to the same dimension (Beauvois, 1995; Dubois & Beauvois, 2005; Dubois, 2005), somehow complicates the model linking normative clearsightedness with a positive evaluation. It suggests indeed that while clearsightedness of some norms will help first of all to get a good evaluation on the dimension of social utility, clearsightedness of other norms will help above all to get a good evaluation on the dimension of social desirability. These considerations were the foundation of this work and led to our first study. However, we reached some unexpected results that prompted us thereafter to reconsider the pertinence to attach the notion of clearsightedness to particular types of content (internality, self-sufficiency, etc.), which led us to propose two new notions: clearsightedness of social utility and clearsightedness of social desirability. Two new studies were thus executed to challenge this proposal. While these researches support as a whole that clearsightedness of social utility and social desirability are better indicators of positive evaluation than clearsightedness of social norms of judgement, they also raised new questions, which led us, in a third time, to wonder about what will determine the dominating social value in an evaluative situation. Our last three studies were designed to this purpose and helped to support the idea, in conclusion of this work, that the clearsightedness of the social value of judgements would bring a positive evaluation only if this clearsightedness is combined with a kind of clearsightedness of the social value of elements constituting the interaction's situation.

Gestión de encuestas on-line dinámicas con estímulo (GEODE)

El presente proyecto ha sido pergeñado como una aplicación que pretende resolver las dos carencias principales detectadas en los sistemas clásicos de encuestas on-line gratuitos: por un lado, resultan estáticos (en el sentido de que las encuestas no son dinámicas en función de las respuestas acumuladas) y, por otro, no ofrecen al individuo encuestado el conocimiento que necesita (como máximo devolverán información agrupada de acuerdo a los resultados globales obtenidos sin retornar un análisis comparativo del grupo frente a la del usuario).

Trends in smoking and lung cancer mortality in Switzerland.

Patterns of cigarette smoking in Switzerland were analyzed on the basis of sales data (available since 1924) and national health surveys conducted in the last decade. There was a steady and substantial increase in cigarettes sales up to the early 1970s. Thereafter, the curve tended to level off around an average value of 3,000 cigarettes per adult per year. According to the 1981-1983 National Health Survey, 37% of Swiss men were current smokers, 25% were ex-smokers, and 39% were never smokers. Corresponding porportions in women were 22, 11, and 67%. Among men, smoking prevalence was higher in lower social classes, and some moderate decline was apparent from survey data over the period 1975-1981 mostly in later middle-age. Trends in lung cancer death certification rates over the period 1950-1984 were analyzed using standard cross-sectional methods and a log-linear Poisson model to isolate the effects of age, birth cohort, and year of death. Mortality from lung cancer increased substantially among Swiss men between the early 1950s and the late 1970s, and levelled off (around a value of 70/100,000 men) thereafter. Among women, there has been a steady upward trend which started in the mid-1960s, and continues to climb steadily, although lung cancer mortality is still considerably lower in absolute terms (around 8/100,000 women) than in several North European countries or in North America. Cohort analyses indicate that the peak rates in men were reached by the generation born around 1910 and mortality stabilized for subsequent generations up to the 1930 birth cohort. Among females, marked increases were observed in each subsequent birth cohort. This pattern of trends is consistent with available information on smoking prevalence in successive generations, showing a peak among men for the 1910 cohort, but steady upward trends among females. Over the period 1980-1984, about 90% of lung cancer deaths among Swiss men and about 40% of those among women could be attributed to smoking (overall proportion, 85%).

Repeated Double-Poling Sprint Training in Hypoxia by Competitive Cross-country Skiers.

PURPOSE: Repeated-sprint training in hypoxia (RSH) was recently shown to improve repeated-sprint ability (RSA) in cycling. This phenomenon is likely to reflect fiber type-dependent, compensatory vasodilation, and therefore, our hypothesis was that RSH is even more beneficial for activities involving upper body muscles, such as double poling during cross-country skiing. METHODS: In a double-blinded fashion, 17 competitive cross-country skiers performed six sessions of repeated sprints (each consisting of four sets of five 10-s sprints, with 20-s intervals of recovery) either in normoxia (RSN, 300 m; FiO2, 20.9%; n = 8) or normobaric hypoxia (RSH, 3000 m; FiO2, 13.8 %; n = 9). Before (pre) and after (post) training, performance was evaluated with an RSA test (10-s all-out sprints-20-s recovery, until peak power output declined by 30%) and a simulated team sprint (team sprint, 3 × 3-min all-out with 3-min rest) on a double-poling ergometer. Triceps brachii oxygenation was measured by near-infrared spectroscopy. RESULTS: From pretraining to posttraining, peak power output in the RSA was increased (P < 0.01) to the same extent (29% ± 13% vs 26% ± 18%, nonsignificant) in RSH and in RSN whereas the number of sprints performed was enhanced in RSH (10.9 ± 5.2 vs 17.1 ± 6.8, P < 0.01) but not in RSN (11.6 ± 5.3 vs 11.7 ± 4.3, nonsignificant). In addition, the amplitude in total hemoglobin variations during sprints throughout RSA rose more in RSH (P < 0.01). Similarly, the average power output during all team sprints improved by 11% ± 9% in RSH and 15% ± 7% in RSN. CONCLUSIONS: Our findings reveal greater improvement in the performance of repeated double-poling sprints, together with larger variations in the perfusion of upper body muscles in RSH compared with those in RSN.
