The team comprising Jean-Claude Juncker’s Commission was revealed on 10 September 2014: does it herald a new start for Justice and Home Affairs (JHA) cooperation in the EU? This essay outlines the main structural and thematic changes introduced by the new Commission, in particular those with direct or indirect relevance to EU JHA or the Area of Freedom, Security and Justice (AFSJ) policies. It also reflects on the new institutional configuration and what it means for the substantive work of the new Commission services and for their intra- and inter-institutional relations. The essay concludes with a set of proposed policy priorities for the new Commission.

The purpose was to advance research and clinical methodology for assessing psychopathology by testing the international generalizability of an 8-syndrome model derived from collateral ratings of adult behavioral, emotional, social, and thought problems. Collateral informants rated 8,582 18-59-year-old residents of 18 societies on the Adult Behavior Checklist (ABCL). Confirmatory factor analyses tested the fit of the 8-syndrome model to ratings from each society. The primary model fit index (Root Mean Square Error of Approximation) showed good model fit for all societies, while secondary indices (Tucker Lewis Index, Comparative Fit Index) showed acceptable to good fit for 17 societies. Factor loadings were robust across societies and items. Of the 5,007 estimated parameters, 4 (0.08%) were outside the admissible parameter space, but 95% confidence intervals included the admissible space, indicating that the 4 deviant parameters could be due to sampling fluctuations. The findings are consistent with previous evidence for the generalizability of the 8-syndrome model in self-ratings from 29 societies, and support the 8-syndrome model for operationalizing phenotypes of adult psychopathology from multi-informant ratings in diverse societies. © 2014 Asociación Española de Psicología Conductual.

This study tested the multi-society generalizability of an eight-syndrome assessment model derived from factor analyses of American adults' self-ratings of 120 behavioral, emotional, and social problems. The Adult Self-Report (ASR; Achenbach and Rescorla 2003) was completed by 17,152 18-59-year-olds in 29 societies. Confirmatory factor analyses tested the fit of self-ratings in each sample to the eight-syndrome model. The primary model fit index (Root Mean Square Error of Approximation) showed good model fit for all samples, while secondary indices showed acceptable to good fit. Only 5 (0.06%) of the 8,598 estimated parameters were outside the admissible parameter space. Confidence intervals indicated that sampling fluctuations could account for the deviant parameters. Results thus supported the tested model in societies differing widely in social, political, and economic systems, languages, ethnicities, religions, and geographical regions. Although other items, societies, and analytic methods might yield different results, the findings indicate that adults in very diverse societies were willing and able to rate themselves on the same standardized set of 120 problem items. Moreover, their self-ratings fit an eight-syndrome model previously derived from self-ratings by American adults. The support for the statistically derived syndrome model is consistent with previous findings for parent, teacher, and self-ratings of 11/2-18-year-olds in many societies. The ASR and its parallel collateral-report instrument, the Adult Behavior Checklist (ABCL), may offer mental health professionals practical tools for the multi-informant assessment of clinical constructs of adult psychopathology that appear to be meaningful across diverse societies. © 2014 Springer Science+Business Media New York.

Introduction La progression de la maladie rénale chronique (MRC) augmente le risque des maladies cardiovasculaires. L’hypertension, le diabète et la dyslipidémie sont à la fois des facteurs de risque et des comorbidités de la MRC. Chez les individus souffrant de MRC, la persistance et l’observance du traitement de ces facteurs de risque, i.e. le traitement antihypertenseur (TAH), le traitement hypolipémiant (THL) et le traitement antidiabétique (TAD) contribuent à réduire le risque de mortalité et de morbidité cardiovasculaires. Néanmoins, la persistance et l’observance de ces traitements restent encore peu étudiées chez les individus ayant la MRC. Objectifs: Spécifiquement pour chacun des trois traitements (TAH, THL et TAD), une étude de cohorte a été menée dans le but : 1) d’estimer la persistance à prendre le traitement un an après le début du traitement; 2) d’estimer l’observance du traitement au cours de l’année suivant le début du traitement chez les persistants; 3) d’identifier les facteurs associés à la persistance; et 4) d’identifier les facteurs associés à l’observance. Méthodologie: Nous avons utilisé les banques de données administratives de la Régie de l’assurance maladie du Québec (RAMQ) pour mener trois études de cohorte chez les personnes âgées de 18 ans ou plus. Une étude a été conduite chez les individus qui ont commencé un TAH, l’autre conduite chez les patients ayant commencé un THL et la dernière menée chez les nouveaux utilisateurs de TAD. Les individus qui poursuivaient encore leur traitement un an après son début ont été considérés persistants. Parmi les persistants, les patients qui ont eu une proportion de jours couverts (PJC) ≥ 80 % ont été considérés observants. Les facteurs associés à la persistance et ceux associés à l’observance ont été identifiés à l’aide d’une régression de Poisson modifiée. Résultats: Parmi les 7 119 patients ayant débuté un TAH, 78,8 % ont été persistants et 87,7 % des persistants ont été observants. Les individus qui étaient plus susceptibles d’être persistants se trouvaient dans le groupe des utilisateurs de monothérapie d’inhibiteurs de l’enzyme de conversion de l’angiotensine (IECA) (Rapport de prévalences (RP) : 1,20; intervalle de confiance (IC) à 95 % : 1,13-1,27), d’antagonistes du récepteur de l’angiotensine II (ARA) (1,22; 1,14-1,31), de bloquants des canaux calciques (BCC) (1,20; 1,14-1,26), de bêta-bloquants (BB) (1,16; 1,10-1,23) et de multithérapie (1,31; 1,25-1,38) (référence : monothérapie de diurétiques (DIU)). Les individus qui étaient plus susceptibles d’être observants étaient les utilisateurs de monothérapie d’IECA (1,08; 1,03-1,04), de BB (1,10; 1,05-1,15), de BCC (1,10; 1,05-1,15) et de multithérapie. Des 14 607 individus ayant débuté un THL, 80,7 % ont persisté à le prendre; de ces derniers, 88,7 % étaient observants du THL. Les patients qui étaient plus susceptibles d’être persistants étaient ceux ayant un statut socio-économique (SSE) faible (1,03; 1,01-1,06) (référence : SSE élevé) et ceux dont le traitement initial avait été prescrit par un néphrologue (1,06; 1,04-1,09) (référence : omnipraticien). Les individus qui étaient plus susceptibles d’être observants étaient ceux âgés ≥ 66 ans (référence : 18-65) (1,04; 1,01-1,07), ceux ayant un SSE faible (1,08; 1,06-1,10) et ceux qui avaient pris plus de 12 médicaments différents (référence : <7) (1,03; 1.00-1,05). Sur un total de 6 671 individus ayant débuté un TAD, 76,9 % ont persisté à prendre le traitement. Parmi les persistants, 87,9 % étaient observants. Les individus ayant un SSE faible (1,04; 1,01-1,07) (référence : SSE élevé) ou une multithérapie (1,12; 1,08-1,16) (référence : monothérapie de metformine) étaient plus susceptibles d’être persistants, tout comme ceux ayant une comorbidité dont l’hypertension artérielle (1,04; 1,01-1,07), la dyslipidémie (1,06; 1,03-1,10), l’accident vasculaire cérébral (AVC) (1,05; 1,01-1,11) ou la maladie coronarienne (1,03; 1,01-1,06). Les individus plus susceptibles d’être observants étaient ceux ayant un SSE moyen (1,03; 1,01-1,07) ou une multithérapie (1,06; 1,03-1,09). Conclusion: Peu importe le traitement initié par les individus souffrant de MRC, environ 30% des patients ne seraient pas persistants un an après le début du traitement ou observants dans l’année suivant l’initiation. Certains facteurs sont associés de façon consistante à la persistance, par exemple l’AVC, la maladie coronarienne et le nombre de visites médicales, alors que l’âge et le SSE sont associés à l’observance peu importe que le traitement initial soit un TAH, un THL ou un TAD.

Interleukin(IL)-18 is a pleiotrophic cytokine with functions in immune modulation, angiogenesis and bone metabolism. In this study, the potential of IL-18 as an immunotherapy for prostate cancer (PCa) was examined using the murine model of prostate carcinoma, RM1 and a bone metastatic variant RM1(BM)/B4H7-luc. RM1 and RM1(BM)/B4H7-luc cells were stably transfected to express bioactive IL-18. These cells were implanted into syngeneic immunocompetent mice, with or without an IL-18-neutralising antibody (αIL-18, SK113AE4). IL-18 significantly inhibited the growth of both subcutaneous and orthotopic RM1 tumors and the IL-18 neutralizing antibody abrogated the tumor growth-inhibition. In vivo neutralization of interferon-gamma (IFN-γ) completely eliminated the anti-tumor effects of IL-18 confirming an essential role of IFN-γ as a down-stream mediator of the anti-tumor activity of IL-18. Tumors from mice in which IL-18 and/or IFN-γ was neutralized contained significantly fewer CD4+ and CD8+ T cells than those with functional IL-18. The essential role of adaptive immunity was demonstrated as tumors grew more rapidly in RAG1−/− mice or in mice depleted of CD4+ and/or CD8+ cells than in normal mice. The tumors in RAG1−/− mice were also significantly smaller when IL-18 was present, indicating that innate immune mechanisms are involved. IL-18 also induced an increase in tumor infiltration of macrophages and neutrophils but not NK cells. In other experiments, direct injection of recombinant IL-18 into established tumors also inhibited tumor growth, which was associated with an increase in intratumoral macrophages, but not T cells. These results suggest that local IL-18 in the tumor environment can significantly potentiate anti-tumor immunity in the prostate and clearly demonstrate that this effect is mediated by innate and adaptive immune mechanisms.

We examined the effects of progressive resistance training (PRT) and supplementation with calcium-vitamin D(3) fortified milk on markers of systemic inflammation, and the relationship between inflammation and changes in muscle mass, size and strength. Healthy men aged 50-79 years (n = 180) participated in this 18-month randomized controlled trial that comprised a factorial 2 x 2 design. Participants were randomized to (1) PRT + fortified milk supplement, (2) PRT, (3) fortified milk supplement, or (4) a control group. Participants assigned to PRT trained 3 days per week, while those in the supplement groups consumed 400 ml day(-1) of milk containing 1,000 mg calcium plus 800 IU vitamin D(3). We collected venous blood samples at baseline, 12 and 18 months to measure the serum concentrations of IL-6, TNF-alpha and hs-CRP. There were no exercise x supplement interactions, but serum IL-6 was 29% lower (95% CI, -62, 0) in the PRT group compared with the control group after 12 months. Conversely, IL-6 was 31% higher (95% CI, -2, 65) in the supplement group compared with the non-supplemented groups after 12 and 18 months. These between-group differences did not persist after adjusting for changes in fat mass. In the PRT group, mid-tibia muscle cross-sectional area increased less in men with higher pre-training inflammation compared with those men with lower inflammation (net difference similar to 2.5%, p < 0.05). In conclusion, serum IL-6 concentration decreased following PRT, whereas it increased after supplementation with fortified milk concomitant with changes in fat mass. Furthermore, low-grade inflammation at baseline restricted muscle hypertrophy following PRT.
