The changing preference of T and B cells for partners as T-dependent antibody responses develop.

Recirculating virgin CD4+ T cells spend their life migrating between the T zones of secondary lymphoid tissues where they screen the surface of interdigitating dendritic cells. T-cell priming starts when processed peptides or superantigen associated with class II MHC molecules are recognised. Those primed T cells that remain within the lymphoid tissue move to the outer T zone, where they interact with B cells that have taken up and processed antigen. Cognate interaction between these cells initiates immunoglobulin (Ig) class switch-recombination and proliferation of both B and T cells; much of this growth occurs outside the T zones B cells migrate to follicles, where they form germinal centres, and to extrafollicular sites of B-cell growth, where they differentiate into mainly short-lived plasma cells. T cells do not move to the extrafollicular foci, but to the follicles; there they proliferate and are subsequently involved in the selection of B cells that have mutated their Ig variable-region genes. During primary antibody responses T-cell proliferation in follicles produces many times the peak number of T cells found in that site: a substantial proportion of the CD4+ memory T-cell pool may originate from growth in follicles.

Origen biogeogràfic i risc de varicel.la entre la població immigrant adulta de Catalunya

Es tracta de un estudi observacional longitudinal durant 2 anys naturals (07/2004 - 06/2006) i multicèntric (4 centres d’atenció primària) on es van monitoritzar i comparar les incidències de varicel.la registrades en les diferents poblacions ateses segons una classificació basada en el seu origen biogeogràfic. Les taxes d’incidència obtingudes, estandaritzades x 1000/any van ser, en ordre creixent: holoàrtics 2,17 (IC 95%: 1,95-2,39); autòctons 2,25 (IC 95%: 2,02-2,47); immigrants 3,59 (IC 95%: 2,92-4,26); neotropicals 4,50 (IC 95%: 3,28-5,71); no-holoàrtics 5,38 (IC 95%4,27-6,14); paleotropicals asiàtics 7,03 (IC 95%: 4,77-9,28) i paleotropicals etiòpics 7,05 (IC 95%: 1,12-23,58). Les diferències obtingudes en relació a la població autòctona es van centrar en los immigrants d’origen neotropical (raó d’incidència estandaritzada = 2,07; o un excés de 4,5 casos x 1000 habitants) i paleotropical asiàtica =3,24; o un excés de 9,6 casos x 1000 habitants) En conclusió, la població d’origen indostànic i, en menor grau, la d’origen sud-americà poden tenir una vulnerabilitat a la varicel.la superior al de la població autòctona.

Hàbit tabàquic entre els docents de les Illes Balears.

Volem descriure la prevalença de fumadors entre els professors de primària i secundària de les Illes Balears i analitzar la seva percepció com a model conductual respecte al tabaquisme per als alumnes. L’estudi descriptiu transversal inclou 36 centres escolars amb participació total de 828 professors. Un 22% de professors es declararen fumadors, encara que un 67% del total de professors afirmà que una raó important per no fumar seria donar exemple als alumnes, manca compliment de la legislació vigent sobre l'ús del tabac en els centres docents.

The Swiss Systemic lupus erythematosus Cohort Study (SSCS) - cross-sectional analysis of clinical characteristics and treatments across different medical disciplines in Switzerland.

OBJECTIVES: To describe disease characteristics and treatment modalities in a multidisciplinary cohort of systemic lupus erythematosus (SLE) patients in Switzerland. METHODS: Cross-sectional analysis of 255 patients included in the Swiss SLE Cohort and coming from centres specialised in Clinical Immunology, Internal Medicine, Nephrology and Rheumatology. Clinical data were collected with a standardised form. Disease activity was assessed using the Safety of Estrogens in Lupus Erythematosus National Assessment-SLE Disease Activity Index (SELENA-SLEDAI), an integer physician's global assessment score (PGA) ranging from 0 (inactive) to 3 (very active disease) and the erythrocyte sedimentation rate (ESR). The relationship between SLE treatment and activity was assessed by propensity score methods using a mixed-effect logistic regression with a random effect on the contributing centre. RESULTS: Of the 255 patients, 82% were women and 82% were of European ancestry. The mean age at enrolment was 44.8 years and the median SLE duration was 5.2 years. Patients from Rheumatology had a significantly later disease onset. Renal disease was reported in 44% of patients. PGA showed active disease in 49% of patients, median SLEDAI was 4 and median ESR was 14 millimetre/first hour. Prescription rates of anti-malarial drugs ranged from 3% by nephrologists to 76% by rheumatologists. Patients regularly using anti-malarial drugs had significantly lower SELENA-SLEDAI scores and ESR values. CONCLUSION: In our cohort, patients in Rheumatology had a significantly later SLE onset than those in Nephrology. Anti-malarial drugs were mostly prescribed by rheumatologists and internists and less frequently by nephrologists, and appeared to be associated with less active SLE.

"Michael's Game," a card game for the treatment of psychotic symptoms.

Objective: "Michael's Game" is a card game which aims at familiarizing healthcare professionals and patients with cognitive therapy of psychotic symptoms. The present study tests the feasibility and the impact of the intervention in naturalistic settings.Methods: 135 patients were recruited in 11 centres. They were assessed pre- and post-tests with the Beck Cognitive Insight Scale (BCIS) and the Peters Delusion Inventory-21 items (PDI-21).Results: Data about 107 patients were included in the entire analyses. Significant improvements were observed on BCIS subscales as well as a reduction of severity of conviction and preoccupation scores on the PDI-21. The intervention has a moderate effect on the PDI-21 preoccupation and conviction as well as the BCIS subscales. Patients who benefit the most from the program are patients who have a low degree of self-reflectiveness and patients who are concomitantly preoccupied by their symptoms.Conclusion: The present study supports the feasibility and effectiveness of "Michael's Game" in naturalistic settings.Practical implications: The game seems to be a useful tool for patients with psychotic disorders.

Women and Cancer in Ireland: 1994-2001

Although prevention is the primary aim of cancer control, early diagnosis and effective treatment are also central to reducing disability and death from cancer. Research in Ireland and internationally has shown major differences between women in the stage (extent) of their cancer when first diagnosed, in access to screening, and in the type of treatment received. These factors have also been shown to determine the rate of cure of cancers and the length of survival for those not cured. Many countries, including Ireland, have developed cancer policies in the past decade, with the aim of improving access, and ensuring that all cancer patients have appropriate, and evidence-based, treatment. These changes have major implications for women in Ireland, for example in the provision of breast and cervical screening programmes and in the expansion of specialist treatment centres for breast cancer.

National Rare Disease Plan for Ireland 2014-2018

  This is a generic policy framework for rare diseases. Its scope is broad and it applies to all rare diseases, which can number up to 8,000 diseases affecting millions of EU citizens. This policy framework envisages a combined approach with our EU partners and Northern Ireland to diagnose and treat people with rare diseases. We must deepen links with facilities and institutions in other countries where specialist services are available that may be absent in Ireland. The plan elaborates on Ireland’s participation in European Reference Networks, which is the networking of knowledge and expertise through reference centres and teams of experts. These links are emphasized in the report to address the care of patients with rare diseases at both national and European levels. Download the report here

Policy Diffusion: An Agent-Based Approach

Methods like Event History Analysis can show the existence of diffusion and part of its nature, but do not study the process itself. Nowadays, thanks to the increasing performance of computers, processes can be studied using computational modeling. This thesis presents an agent-based model of policy diffusion mainly inspired from the model developed by Braun and Gilardi (2006). I first start by developing a theoretical framework of policy diffusion that presents the main internal drivers of policy diffusion - such as the preference for the policy, the effectiveness of the policy, the institutional constraints, and the ideology - and its main mechanisms, namely learning, competition, emulation, and coercion. Therefore diffusion, expressed by these interdependencies, is a complex process that needs to be studied with computational agent-based modeling. In a second step, computational agent-based modeling is defined along with its most significant concepts: complexity and emergence. Using computational agent-based modeling implies the development of an algorithm and its programming. When this latter has been developed, we let the different agents interact. Consequently, a phenomenon of diffusion, derived from learning, emerges, meaning that the choice made by an agent is conditional to that made by its neighbors. As a result, learning follows an inverted S-curve, which leads to partial convergence - global divergence and local convergence - that triggers the emergence of political clusters; i.e. the creation of regions with the same policy. Furthermore, the average effectiveness in this computational world tends to follow a J-shaped curve, meaning that not only time is needed for a policy to deploy its effects, but that it also takes time for a country to find the best-suited policy. To conclude, diffusion is an emergent phenomenon from complex interactions and its outcomes as ensued from my model are in line with the theoretical expectations and the empirical evidence.Les méthodes d'analyse de biographie (event history analysis) permettent de mettre en évidence l'existence de phénomènes de diffusion et de les décrire, mais ne permettent pas d'en étudier le processus. Les simulations informatiques, grâce aux performances croissantes des ordinateurs, rendent possible l'étude des processus en tant que tels. Cette thèse, basée sur le modèle théorique développé par Braun et Gilardi (2006), présente une simulation centrée sur les agents des phénomènes de diffusion des politiques. Le point de départ de ce travail met en lumière, au niveau théorique, les principaux facteurs de changement internes à un pays : la préférence pour une politique donnée, l'efficacité de cette dernière, les contraintes institutionnelles, l'idéologie, et les principaux mécanismes de diffusion que sont l'apprentissage, la compétition, l'émulation et la coercition. La diffusion, définie par l'interdépendance des différents acteurs, est un système complexe dont l'étude est rendue possible par les simulations centrées sur les agents. Au niveau méthodologique, nous présenterons également les principaux concepts sous-jacents aux simulations, notamment la complexité et l'émergence. De plus, l'utilisation de simulations informatiques implique le développement d'un algorithme et sa programmation. Cette dernière réalisée, les agents peuvent interagir, avec comme résultat l'émergence d'un phénomène de diffusion, dérivé de l'apprentissage, où le choix d'un agent dépend en grande partie de ceux faits par ses voisins. De plus, ce phénomène suit une courbe en S caractéristique, poussant à la création de régions politiquement identiques, mais divergentes au niveau globale. Enfin, l'efficacité moyenne, dans ce monde simulé, suit une courbe en J, ce qui signifie qu'il faut du temps, non seulement pour que la politique montre ses effets, mais également pour qu'un pays introduise la politique la plus efficace. En conclusion, la diffusion est un phénomène émergent résultant d'interactions complexes dont les résultats du processus tel que développé dans ce modèle correspondent tant aux attentes théoriques qu'aux résultats pratiques.
