Intellectual outcome in children and adolescents with acute lymphoblastic leukaemia treated with chemotherapy alone: age- and sex-related differences.

One of the most relevant concerns in long-term survivors of paediatric acute lymphoblastic leukaemia (ALL) is the development of neuropsychological sequelae. The majority of the published studies report on patients treated with chemotherapy and prophylactic central nervous system (CNS) irradiation, little is known about the outcome of patients treated with chemotherapy-only regimens. Using the standardised clinical and neuropsychological instruments of the SPOG Late Effects Study, the intellectual performance of 132 paediatric ALL patients treated with chemotherapy only was compared to that of 100 control patients surviving from diverse non-CNS solid tumours. As a group, ALL and solid tumour survivors showed normal and comparable intellectual performances (mean global IQ 104.6 in both groups). The percentage of patients in the borderline range (global IQ between 70 and 85) was comparable and not higher as expected (10% cases and 13% controls, expected 16%). Only 2 (2%) of the former ALL and 1 (1%) of the solid tumour patients were in the range of mental retardation (global IQ<70). Former known risk factors described in children treated with prophylactic CNS irradiation, like a younger age at diagnosis of ALL and female gender, remained valid in chemotherapy-only treated patients. The abandonment of prophylactic CNS irradiation and its replacement by a more intensive systemic and intrathecal chemotherapy led to a reduction, but not the disappearance of late neuropsychological sequelae.

Proposta metodològica per a l'estudi dels oients de ràdio a Catalunya a finals de la guerra civil: el cas de Girona, 1937-1939

Aquest treball és una proposta metodològica per l’elaboració d’un estudi històric d’oients de ràdio. La proposta fa un estudi de cas, centrat en la ciutat de Girona entre 1937 i 1939, per tal de demostrar que la metodologia aplicada ha funcionat. És el primer que es fa amb dades completament objectives per aproximar-se a la audiència històrica de la ràdio. A partir d’aquest treball que troba, prova i valida les eines que han de servir per poder fer un “EGM històric”, es pot concloure per exemple que a Girona l’any 1937, en plena Guerra Civil, hi havia almenys 7.380 persones que podien escoltar diàriament la ràdio, o que un 7% de la població tenia un aparell de ràdio a casa seva.

Variació dels estatges vegetals a l'àrea de la Bruguera (Girona) en els darrers cent anys

Treball de recerca realitzat per alumnes d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit cientí­fic del Jovent l'any 2009. Aquest treball s'ha basat en la comparació altitudinal de determinades espècies vegetals (i per tant dels estatges) respecte els últims cent anys en una zona de la vall de Ribes; concretament des de la serra de St. Amanç fins a la població de Bruguera, passant per els Llisos del Taga. La realització del treball implica primerament la recerca d'estudis i dades anteriors fets sobre el tema, que generalment es basaria en dos estudis ja esmentats en el treball, els quals són un catàleg florístic de la vall de Ribes (de Josep Vigo) i un article de característiques molt semblants al nostre treball (de Jonathan Lenoir), així com també l¡elecció de la metodologia i de les espècies a estudiar. L'altra part es basa en fer un comptatge i identificació de les espècies trobades en diferents zones. En el moment de fer la delimitació de les zones hem tingut en compte l'alçada i l'orientació i s'han subdividit aquestes zones en quadrants per facilitar el comptatge i identificació. Una vegada comparats els resultats amb els estudis fets anteriorment s'ha arribat a la conclusió que hi havia un canvi altitudinal de les espècies prou significatiu. Unes de les interpretacions d'aquest resultat observat podria lligar-se al canvi de temperatures que ha sofert la vall en els últims anys degut al canvi climàtic.

Cognitive and Emotional Deficits Associated with Minor and Serious Delinquency in High-Risk Adolescents

This study aims at evaluating how minor and serious delinquency relates to cognitive and emotional functioning in high-risk adolescents, taking problematic substance use into account. In 80 high-risk adolescent males (13-19 years), the frequency of minor and serious offences committed over the last year was predicted, in multiple regression analyses, from problematic substance use, intellectual efficiency, trait impulsivity, alexithymia (inability to express feelings in words), and cognitive coping strategies. Both minor and serious delinquency were more frequent in adolescents with more problematic substance use and higher intellectual efficacy. Minor delinquency was further related to a tendency to act out when experiencing negative emotions, and difficulties in focusing energy on instrumental action when under stress; while serious delinquency was predominantly and strongly related to rigid and dichotomous thinking. The results underline the heterogeneous nature of delinquency, minor offences being primarily associated with emotional regulation deficits, while major offences are related with a lack of cognitive flexibility.

Delinquency in male adolescents: the role of alexithymia and family structure

The purpose of this study was to examine the linkages between alexithymia and delinquency in male adolescents (age ranging from 14 to 18 years), and to investigate whether alexithymia was a good discriminatory factor for juvenile delinquency. Thirty-six offender adolescents and 46 non-offender control adolescents participated in the study and completed the 20-item Toronto Alexithymia Scale (TAS-20) (alexithymia), the Revised Children's Manifest Anxiety Scale (R-CMAS) (anxiety), the Liste d'Adjectifs Bipolaires et en Echelles de Likert (LABEL) (personality-Big Five) and demographic data. Findings revealed that the adolescents of the offender group scored high on alexithymia and that proportion of disrupted family structure in the offender group is higher than in the control group. Logistic regressions confirmed that alexithymia and family structure are the strongest discriminatory factors for juvenile delinquency. Limitations and clinical implications are discussed, and recommendations for future research are provided

Suicidal expression among school-attending adolescents in a middle-income sub-Saharan country.

We investigated correlates for suicidal expression among adolescents in the Seychelles. Data on 1,432 students (52% females) were derived from the Global School-based Health Survey. Participants were divided into three groups: those with no suicidal behavior (N = 1,199); those with suicide ideation/SI (N = 89); and those reporting SI with a plan to carry out a suicide attempt/SISP (N = 139), each within a 12-month recall period. Using multinomial logistic regression, we examined the strength of associations with social, behavioral and economic indicators while adjusting for covariates. Sixteen percent of school-attending adolescents reported a suicidal expression (10% with a plan/6.2% without). Those reporting SI were younger (relative risk ratio RRR = 0.81; CI = 0.68-0.96), indicated signs of depression (RRR = 1.69; CI = 1.05-2.72) and loneliness (RRR=3.36; CI =1.93-5.84). Tobacco use (RRR = 2.34; CI = 1.32-4.12) and not having close friends (RRR = 3.32; CI = 1.54-7.15) were significantly associated with SI. Those with SISP were more likely to be female (RRR = 0.47; 0.30-0.74), anxious (RRR = 3.04; CI = 1.89-4.88) and lonely (RRR = 1.74; CI = 1.07-2.84). Having no close friends (RRR = 2.98; 1.56-5.69) and using tobacco (RRR = 2.41; 1.48-3.91) were also strongly associated. Having parents who were understanding was protective (RRR = 0.50; CI = 0.31-0.82). Our results suggest that school health promotion programs may benefit from targeting multiple factors associated with suicidal expression. More research, particularly multilevel designs are needed to identify peer and family influences which may modify associations with suicidality.

Recerca versus docència en una experiència d'internalització dels estudis de Geografia a la Universitat de Girona: The faces of landscape, Catalonia and North Karelia = Research versus teaching in one experience of internationalization of the Geography degree studies in the University of Girona: The faces of landscape, Catalonia and North Karelia

Un dels reptes cabdals de la Universitat és enllaçar l’experiència de recerca amb la docència, així com promoure la internacionalització dels estudis, especialment a escala europea, tenint present que ambdues poden actuar com a catalitzadores de la millora de la qualitat docent. Una de les fórmules d’internacionalització és la realització d’assignatures compartides entre universitats de diferents països, fet que suposa l’oportunitat d’implementar noves metodologies docents. En aquesta comunicació es presenta una experiència en aquesta línia desenvolupada entre la Universitat de Girona i la Universitat de Joensuu (Finlàndia) en el marc dels estudis de Geografia amb la realització de l’assignatura 'The faces of landscape: Catalonia and North Karelia'. Aquesta es desenvolupa al llarg de dues setmanes intensives, una en cadascuna de les Universitats. L’objectiu és presentar i analitzar diferents significats del concepte paisatge aportant també metodologies d’estudi tant dels aspectes físics i ecològics com culturals que s’hi poden vincular i que són les que empren els grups de recerca dels professors responsables de l’assignatura. Aquesta part teòrica es completa amb una presentació de les característiques i dinàmiques pròpies dels paisatges finlandesos i catalans i una sortida de camp. Per a la part pràctica es constitueixen grups d’estudi multinacionals que treballen a escala local algun dels aspectes en els dos països, es comparen i es realitza una presentació i defensa davant del conjunt d’estudiants i professorat. La llengua vehicular de l’assignatura és l’anglès.

Screening for elevated blood pressure in children and adolescents: a critical appraisal.

Although screening for elevated blood pressure (BP) in adults is beneficial, evidence of its beneficial effects in children is not clear. Elevated BP in children is associated with atherosclerosis early in life and tracks across the life course. However, because of the high variability in BP, tracking is weak, and having an elevated BP in childhood has a low predictive value for having elevated BP later in life. The absolute risk of cardiovascular diseases associated with a given level of BP in childhood and the long-term effect of treatment beginning in childhood are not known. No study has experimentally evaluated the benefits and harm of BP screening in children. One modeling study indicates that BP screen-and-treat strategies in adolescents are moderately cost-effective but less cost-effective than population-wide interventions to decrease BP for the reduction of coronary heart diseases. The US National Heart, Lung, and Blood Institute and the European Society of Hypertension recommend that children 3 years of age and older have their BP measured during every health care visit. According to the US Preventive Services Task Force, there is no sufficient evidence to recommend for or against screening, but their recommendations have to be updated. Whether the benefits of universal BP screening in children outweigh the harm has to be determined. Studies are needed to assess the absolute risk of cardiovascular diseases associated with elevated BP in childhood, to evaluate how to simplify the identification of elevated BP, to evaluate the long-term benefits and harm of treatment beginning in childhood, and to compare universal and targeted screening strategies.

Substance use among sportive adolescents in the French-speaking part of Switzerland

CONTEXTE: Pour diverses raisons, les adultes et en particulier les parents croient que la pratique sportive à l'adolescence est un facteur de protection contre les comportements à risque tels que la consommation de substances. Les preuves présentes à l'intérieur de la littérature ne sont toutefois pas concluantes à ce sujet. Le principal objectif de notre étude était donc de comparer la prévalence de la consommation de substances psychoactives (licites et illicites) et de substances ergogéniques et dopantes entre les jeunes de Suisse Romande pratiquant un sport et ceux n'en pratiquant pas.METHODES: À l'aide de plusieurs méthodes de recrutement, des adolescents sportifs et non sportifs âgés de 16 à 20 ans furent invités à répondre à un questionnaire anonyme en ligne sur leur consommation de substances. Les substances psychoactives étudiées furent principalement le tabac, l'alcool, et le cannabis. Le dopage a été limité à la volonté d'améliorer les performances tout en utilisant des produits interdits selon l'Agence Mondiale Antidopage (liste 2009). Plusieurs produits légaux liés à la pratique sportive ont également été étudiés. Sur une période de 10 mois, un total de 1303 questionnaires ont été complétés. De l'échantillon final pondéré, les réponses de 1247 sujets éligibles ont été analysées.RESULTATS ET CONCLUSIONS: Dans l'ensemble, l'effet protecteur d'une pratique sportive contre l'utilisation de substances psychoactives semble dépendre de la substance à l'étude.Les jeunes non-sportifs sont plus susceptibles de fumer que les sportifs, et, parmi ces derniers, ceux évoluant dans un contexte de loisir sont plus susceptibles de fumer que ceux en pratique compétitive. Au contraire, aucune différence concernant l'abus d'alcool n'a été observée entre les adolescents sportifs et non-sportifs, indiquant que la pratique sportive ne représente pas une protection contre l'abus d'alcool. Bien que les jeunes non-sportifs soient deux fois plus susceptibles d'être utilisateurs actuels de cannabis, un jeune sportif sur neuf en a néanmoins consommé dans le dernier mois.Les trois quarts des jeunes sportifs interrogés indiquent utiliser activement des produits pour améliorer leurs performances, confirmant la tendance actuellement perçue. Parmi les substances utilisées pour améliorer les performances sportives, les produits contenant de la caféine, les boissons sportives et les suppléments alimentaires sont les trois plus souvent signalés.Peu de jeunes sportifs en Suisse Romande semblent utiliser des substances bannies par l'Agence Mondiale Antidopage, le cannabis étant celui le plus fréquemment cité.Parmi les jeunes sportifs, ceux en pratique compétitive semblent plus susceptibles d'utiliser des produits pour améliorer leurs performances que ceux évoluant dans un contexte de loisir. En outre, Un lien entre les substances psychoactives et celles prises pour améliorer les performances sportives semblent exister: tous les jeunes sportifs signalant soit fumer, avoir abusé de l'alcool récemment ou consommer actuellement du cannabis ont démontré une consommation plus élevée de produits dopants. L'usage du cannabis comme un moyen d'améliorer les performances sportives semble assez fréquent chez les consommateurs récréatifs de cette substance.Les jeunes sportifs évoluant au niveau international ont montré des taux plus bas d'abus d'alcool et de cannabis.

Age-specific Prevalence of Antibodies to Hepatitis A in Children and Adolescents from Rio de Janeiro, Brazil, 1978 and 1995: Relationship of Prevalence to Environmental Factors

The age-specific prevalence of antibodies to hepatitis A virus (anti-HAV) was determined in two different population groups with low socio-economic status from Rio de Janeiro city, Brazil, whose serum samples were collected 17 years apart (Population 1, 1978; Population 2, 1995). In Population 2, analysis of the anti-HAV prevalence was also carried out with respect to environmental factors. Population 1 was composed of 520 stored sera collected from the umbilical cord of term neonates and children aged 1 month to 6 years. In population 2, 720 serum samples were collected from children and adolescents with ages ranging from 1 to 23 years. The overall prevalence rate of anti-HAV in Population 1 and Population 2 was 65.6% and 32.1%, respectively. In Population 1, the anti-HAV prevalence reached 88% at the age of 3, while in Population 2, it increased from 4.5% in children under the age of 3 to 66% in the group of adolescents over the age of 14. The low exposure to HAV infection in younger children from Population 2 could be a result of improved environmental hygiene and sanitation, as demonstrated by the presence of piped water, waste and sewage disposal systems in most houses from this population group. These findings indicate a possible change in the prevalence of hepatitis A in Rio de Janeiro
