Peripheral blood mononuclear cells from subjects never exposed to Leishmania were stimulated with Leishmania guyanensis. We demonstrated that L. guyanensis-stimulated CD8(+) T cells produced interferon (IFN)- gamma and preferentially expressed the V beta 14 T cell receptor (TCR) gene family. In addition, these cells expressed cutaneous lymphocyte antigen and CCR4 surface molecules, suggesting that they could migrate to the skin. Results obtained from the lesions of patients with localized cutaneous leishmaniaisis (LCL) showed that V beta 14 TCR expression was increased in most lesions (63.5%) and that expression of only a small number of V beta gene families (V beta 1, V beta 6, V beta 9, V beta 14, and V beta 24) was increased. The presence of V beta 14 T cells in tissue confirmed the migration of these cells to the lesion site. Thus, we propose the following sequence of events during infection with L. guyanensis. After initial exposure to L. guyanensis, CD8(+) T cells preferentially expressing the V beta 14 TCR and secreting IFN- gamma develop and circulate in the periphery. During the infection, these cells migrate to the skin at the site of the parasitic infection. The role of these V beta 14 CD8(+) T cells in resistance to infection remains to be determined conclusively.

The hypothalamus plays an essential role in the central nervous system of mammals by among others regulating glucose homeostasis, food intake, temperature, and to some extent blood pressure. Assessments of hypothalamic metabolism using, e.g. (1)H MRS in mouse models can provide important insights into its function. To date, direct in vivo (1)H MRS measurements of hypothalamus have not been reported. Here, we report that in vivo single voxel measurements of mouse hypothalamus are feasible using (1)H MRS at 14.1T. Localized (1)H MR spectra from hypothalamus were obtained unilaterally (2-2.2 microL, VOI) and bilaterally (4-4.4 microL) with a quality comparable to that of hippocampus (3-3.5 microL). Using LCModel, a neurochemical profile consisting of 21 metabolites was quantified for both hypothalamus and hippocampus with most of the Cramér-Rao lower bounds within 20%. Relative to the hippocampus, the hypothalamus was characterized by high gamma-aminobutryric acid and myo-inositol, and low taurine concentrations. When studying transgenic mice with no glucose transporter isoform 8 expressed, small metabolic changes were observed, yet glucose homeostasis was well maintained. We conclude that a specific neurochemical profile of mouse hypothalamus can be measured by (1)H MRS which will allow identifying and following metabolic alterations longitudinally in the hypothalamus of genetic modified models.

The purpose of this study was to assess the relationship between blood pressure (BP) levels and physical activity (PA) domains accounting for overweight/obesity. Adolescents aged 10 to 17 years old were recruited (n = 1021). International Obesity Task Force (IOTF) criteria were used to define overweight and obesity. High BP was defined using the Center of Disease Control and Prevention criteria. Different domains of PA (school activities, sport out of school, and leisure time PA) were assessed using a validated questionnaire. The prevalence of overweight/obesity was 21.9% for boys and 14.8% for girls. Some 13.4% of boys and 10.2% of girls, respectively, had high blood pressure (HBP). A strong and positive association was found between overweight and HBP. After adjustment for body mass index (BMI), total PA was inversely associated with BP. When all PA domains were entered simultaneously in a regression model, and after adjustment for BMI, only sport out of school was significantly and inversely associated with systolic BP [β: -0.82 (-1.50; -0.13)]. These findings open avenue for the early prevention of HBP by the prevention of obesity and promotion of PA.

BACKGROUND: Control of blood pressure (BP) remains a major challenge in primary care. Innovative interventions to improve BP control are therefore needed. By updating and combining data from 2 previous systematic reviews, we assess the effect of pharmacist interventions on BP and identify potential determinants of heterogeneity. METHODS AND RESULTS: Randomized controlled trials (RCTs) assessing the effect of pharmacist interventions on BP among outpatients with or without diabetes were identified from MEDLINE, EMBASE, CINAHL, and CENTRAL databases. Weighted mean differences in BP were estimated using random effect models. Prediction intervals (PI) were computed to better express uncertainties in the effect estimates. Thirty-nine RCTs were included with 14 224 patients. Pharmacist interventions mainly included patient education, feedback to physician, and medication management. Compared with usual care, pharmacist interventions showed greater reduction in systolic BP (-7.6 mm Hg, 95% CI: -9.0 to -6.3; I(2)=67%) and diastolic BP (-3.9 mm Hg, 95% CI: -5.1 to -2.8; I(2)=83%). The 95% PI ranged from -13.9 to -1.4 mm Hg for systolic BP and from -9.9 to +2.0 mm Hg for diastolic BP. The effect tended to be larger if the intervention was led by the pharmacist and was done at least monthly. CONCLUSIONS: Pharmacist interventions - alone or in collaboration with other healthcare professionals - improved BP management. Nevertheless, pharmacist interventions had differential effects on BP, from very large to modest or no effect; and determinants of heterogeneity could not be identified. Determining the most efficient, cost-effective, and least time-consuming intervention should be addressed with further research.

La finalitat d'aquest projecte és aprofundir en el procés d'integració socioeducativa de la joventut migrada a Catalunya, específicament, dels i les joves entre 14 i 18 anys. Entre els resultats destaquem que els ioves tenen un concepte força tancat i excloent del concepte de ciutadania com a estatus , i un baix grau, de coneixement de la diversitat cultural, especialment els joves autòctons, tot i que tenen una actitud de reconeixement i acceptació, favorable a la convivència intercultural, tant al centre educatiu com al seu barri. No obstant, tenen una visió de la diversitat cultural i del fet migratori en clau de coexistència, sense el reconeixement que suposaria un pas més cap a la convivència. La immigració és vista com un col•lectiu vulnerable, amb un baix nivell econòmic i cultural i que també és percebut com un problema i, fins i tot, com a causant de les dificultutats que actualment pateix i travessa el conjunt de la societat. Els joves tendeixen a relacionar-se amb el seu grup cultural, i responen de forma passiva en la comprensió i actuació davant dels problemes i assumptes públics. Entre els elements que valoren per sentir-se ciutadà té una especial importància la llengua. Eis joves que fa més de 10 anys que viuen a Catalunya són els que tendeixen a tenir un sentiment de pertinença cívica amb el lloc de residència. De fet, com mes temps porten els joves estrangers vivint al lloc d’acollida, perden importància elements d’identificació cultural del país d’origen, però la religió, les celebracions populars, l’art i la tendència a formar parella són elements identitaris del lloc d’origen, més estables. Es demana una intervenció urgent en diversos nivells i destinades a diferents agents. Destaquem: la importància d’una acollida afectiva i efectiva; potenciar espais de trobada; treballar els prejudicis; transversalitzar l’educació intercultural; potenciació de l’aprenentatge de la llengua catalana; formació del professorat en competències interculturals.
