Trends over time of virological and immunological characteristics in the Swiss HIV Cohort Study.

BACKGROUND: The long-term outcome of antiretroviral therapy (ART) is not assessed in controlled trials. We aimed to analyse trends in the population effectiveness of ART in the Swiss HIV Cohort Study over the last decade. METHODS: We analysed the odds of stably suppressed viral load (ssVL: three consecutive values <50 HIV-1 RNA copies/mL) and of CD4 cell count exceeding 500 cells/μL for each year between 2000 and 2008 in three scenarios: an open cohort; a closed cohort ignoring the influx of new participants after 2000; and a worst-case closed cohort retaining lost or dead patients as virological failures in subsequent years. We used generalized estimating equations with sex, age, risk, non-White ethnicity and era of starting combination ART (cART) as fixed co-factors. Time-updated co-factors included type of ART regimen, number of new drugs and adherence to therapy. RESULTS: The open cohort included 9802 individuals (median age 38 years; 31% female). From 2000 to 2008, the proportion of participants with ssVL increased from 37 to 64% [adjusted odds ratio (OR) per year 1.16 (95% CI 1.15-1.17)] and the proportion with CD4 count >500 cells/μL increased from 40 to >50% [OR 1.07 (95% CI 1.06-1.07)]. Similar trends were seen in the two closed cohorts. Adjustment did not substantially affect time trends. CONCLUSIONS: There was no relevant dilution effect through new participants entering the open clinical cohort, and the increase in virological/immunological success over time was not an artefact of the study design of open cohorts. This can partly be explained by new treatment options and other improvements in medical care.

1009-004 Lost Island Lake Watershed Final Report

The Lost Island Lake watershed is located in the prairie pothole region, a region dotted with glacial wetlands and shallow lakes. At 1,180 acres, Lost Island Lake is the state's fifth largest natural lake and its watershed is comprised of nearly 1,000 acres of wetland habitat, including Iowa 's largest natural wetland – Barringer Slough. Unfortunately, Lost Island and its associated wetlands are not functioning to their fullest ecological and water quality potential. In 2002 and 2004, Lost Island Lake was categorized as '·impaired'" on Iowa's Impaired Waters List. Frequent algal blooms and suspended solids drastically increase turbidity levels resulting in its impairment. To investigate these concerns, a two-year study and resulting Water Quality Improvement Plan were completed. The water quality study identified an overabundance of non-native common carp (Cyprinus carpio) in the lake and its surrounding wetlands as a primary cause of impairment. The goal of the Lost Island Lake Watershed Enhancement Project is to restore ecological health to Lost Island Lake and its intricate watershed resulting in improved water quality and a diverse native plant and wildlife community. The purpose of this grant is to obtain funding for the construction of two combination fish barriers and water control structures placed at key locations in the watershed within the Blue Wing Marsh complex. Construction of the fish barriers and water control structures would aid restoration efforts by preventing spawning common carp from entering wetlands in the watershed and establishing the ability to manage water levels in large wetland areas. Water level management is crucial in wetland health and exotic fish control. These two structures are part of a larger construction project that involves a total of four combination fish barriers and water control structures and one additional fish barrier. The entire Lost Island Lake Watershed Enhancement Project is a multi-year project, but the construction phase for the fish barriers and water control structures will be completed before December 31, 2011.

The diagnostic challenge of progressive pseudorheumatoid dysplasia (PPRD): A review of clinical features, radiographic features, and WISP3 mutations in 63 affected individuals.

Progressive pseudorheumatoid dysplasia (PPRD) is a genetic, non-inflammatory arthropathy caused by recessive loss of function mutations in WISP3 (Wnt1-inducible signaling pathway protein 3; MIM 603400), encoding for a signaling protein. The disease is clinically silent at birth and in infancy. It manifests between the age of 3 and 6 years with joint pain and progressive joint stiffness. Affected children are referred to pediatric rheumatologists and orthopedic surgeons; however, signs of inflammation are absent and anti-inflammatory treatment is of little help. Bony enlargement at the interphalangeal joints progresses leading to camptodactyly. Spine involvement develops in late childhood and adolescence leading to short trunk with thoracolumbar kyphosis. Adult height is usually below the 3rd percentile. Radiographic signs are relatively mild. Platyspondyly develops in late childhood and can be the first clue to the diagnosis. Enlargement of the phalangeal metaphyses develops subtly and is usually recognizable by 10 years. The femoral heads are large and the acetabulum forms a distinct "lip" overriding the femoral head. There is a progressive narrowing of all articular spaces as articular cartilage is lost. Medical management of PPRD remains symptomatic and relies on pain medication. Hip joint replacement surgery in early adulthood is effective in reducing pain and maintaining mobility and can be recommended. Subsequent knee joint replacement is a further option. Mutation analysis of WISP3 allowed the confirmation of the diagnosis in 63 out of 64 typical cases in our series. Intronic mutations in WISP3 leading to splicing aberrations can be detected only in cDNA from fibroblasts and therefore a skin biopsy is indicated when genomic analysis fails to reveal mutations in individuals with otherwise typical signs and symptoms. In spite of the first symptoms appearing in early childhood, the diagnosis of PPRD is most often made only in the second decade and affected children often receive unnecessary anti-inflammatory and immunosuppressive treatments. Increasing awareness of PPRD appears to be essential to allow for a timely diagnosis. © 2012 Wiley Periodicals, Inc.

In vitro assays and clinical trials in red blood cell aging: Lost in translation.

The age of erythrocyte concentrates (EC) in transfusion medicine and the adverse outcomes when transfusing long-term-stored EC are highly controversial issues. Whereas the definition of a short-term-stored EC or a long-term-stored EC is unclear in clinical trials, data based on in vitro storage assays can help defining a limit in addition of the expiration date. The present review merges together these data in order to highlight an EC age cut-off and points out potential misleading consideration. The analysis of in vitro data highlights the presence of reversible and irreversible storage lesions and demonstrates that red blood cells (RBC) exhibit two limits during storage: one around 2 weeks and another one around 4 weeks of storage. Of particular importance, the first lesions to appear, i.e. the reversible ones, are per se reversible once transfused, whereas the irreversible lesions are not. In clinical trials, the EC age cut-off for short-term storage is in general fewer than 14 days (11 ± 4 days) and more disperse for long-term-stored EC (17 ± 13 days), regardless the clinical outcomes. Taking together, EC age cut-off in clinical trials does not totally fall into line of in vitro aging data, whereas it is the key criteria in clinical studies. Long-term-stored EC considered in clinical trials are not probably old enough to answer the question: "Does transfusion of long-term-stored EC (older than 4 weeks) result in worse clinical outcomes?" Depending on ethical concerns and clinical practices, older EC than currently assayed in clinical trials should have to be considered. These two worlds trying to understand the aging of erythrocytes and the impact on patients do not seem to speak the same language.

Plant sex chromosomes: lost genes with little compensation.

In many animals, gene loss on Y chromosomes is compensated through altered expression of their X-chromosome homologue. Now, however, a new study in plants finds that even genes deleted from the Y show no dosage compensation.

Lost in translation: dietary management of cardiovascular risk factors is seldom implemented.

OBJECTIVE: To assess dietary management of cardiovascular risk factors (CVRFs) in the general population. METHOD: Cross-sectional study conducted between 2009 and 2012 on 4811 participants (2567 women, 58±11years) living in Lausanne, Switzerland. RESULTS: Sixteen percent of participants diagnosed with overweight/obesity reported a slimming diet. Slimming diet was associated with diagnosis of hypertension: Odds ratio and (95% confidence interval): 0.61 (0.40-0.93); older age [0.84 (0.58-1.21), 0.79 (0.53-1.18) and 0.47 (0.27-0.81) for [50-60[, [60-70[ and [70+ years, respectively]; female gender [1.84 (1.36-2.48)] and diagnosis of diabetes [2.16 (1.13-4.12)]. Only 8% of participants diagnosed with hypertension reported a low-salt diet. Low-salt diet was associated with antihypertensive drug treatment [2.17 (1.28-3.68)] and diagnosis of diabetes [2.72 (1.26-5.86)]. One-third of participants diagnosed with dyslipidemia reported a low-fat diet. Low-fat diet was associated with female gender [1.47 (1.17-1.86)]; older age [1.29 (0.89-1.87), 1.71 (1.18-2.48) and 2.01 (1.33-3.03) for [50-60[, [60-70[ and [70+ years, respectively]; hypolipidemic drug treatment [OR=1.68 (1.29-2.18)]; current smoking [0.70 (0.51-0.96)] and obesity [0.67 (0.45-1.00)]. Approximately half of participants diagnosed with diabetes reported an antidiabetic diet. Antidiabetic diet was associated with current smoking [0.44 (0.22-0.88)] and antidiabetic drug treatment [OR=3.26 (1.81-5.86)]. CONCLUSION: Dietary management of CVRFs is seldom implemented in Switzerland.

Novel therapeutic strategies targeting regulatory T cells and downstream TCR signaling in transplantation

Avec plus de 100000 transplantations d'organes solides (TOS) par année dans le monde, la transplantation d'organes reste actuellement l'un des meilleurs traitements disponibles pour de nombreuses maladies en phase terminale. Bien que les médicaments immunosuppresseurs couramment utilisés soient efficaces dans le contrôle de la réponse immune engendrant le rejet aigu d'une greffe, la survie du greffon à long terme ainsi que la présence d'effets secondaires indésirables restent un enjeu considérable en clinique. C'est pourquoi il est nécessaire de trouver de nouvelles approches thérapeutiques innovantes permettant de contrôler la réponse immunitaire et ainsi d'améliorer les résultats à long terme. L'utilisation des lymphocytes T régulateurs (Treg), suppresseurs naturels de la réponse inflammatoire, a fait l'objet de nombreuses études ces dix dernières années, et pourrait être considérée comme un moyen intéressant d'améliorer la tolérance immunologique de la greffe. Cependant, l'un des obstacles de l'utilisation des Treg comme agent thérapeutique est leur nombre insuffisant non seulement en conditions normales, mais en particulier lors d'une forte réponse immune avec expansion de cellules immunitaires alloréactives. En raison des limitations techniques connues pour l'induction des Treg ex-vivo ou in vitro, nous avons dédié la première partie du travail de thèse à la détermination de l'efficacité de l'induction des Treg in vivo grâce à l'utilisation d'un complexe protéique IL-2/JES6-1 (IL2c). Nous avons montré que l'expansion des Treg par IL2c permettait d'augmenter la survie du greffon sur un modèle murin de transplantation de peau avec mismatch entre le donneur et le receveur pour le complexe majeur d'histocompatibilité (CMH). De plus, nous avons vu qu'en combinant IL2c à une inhibition à court terme de la voie de co-stimulation CD40L-CD40 (anti-CD154/MRl, administré au moment de la transplantation) pour empêcher l'activation des lymphocytes T, il est possible d'induire une tolérance robuste à long terme. Finalement, nos résultats soulignent l'importance de cibler une voie de co-stimulation bien particulière. En effet, l'utilisation d'IL2c combinée au blocage de la co-stimulation CD28-B7.1/2 (CTLA-4 Ig) n'induit qu'une faible prolongation de la survie de la greffe et n'induit pas de tolérance. L'application chez l'humain des traitements induisant la tolérance dans des modèles expérimentaux murins ou de primates n'a malheureusement pas montré de résultats probants en recherche clinique ; une des principales raisons étant la présence de lymphocytes B et T mémoires provenant du systeme d immunité acquise. C est pourquoi nous avons testé si la combinaison d'IL2c et MR1 améliorait la survie de la greffe dans des souris pré¬sensibilisées. Nous avons trouvé qu'en présence de lymphocytes B et T mémoires alloréactifs, l'utilisation d'IL2c et MR1 permettait une amélioration de la survie de la greffe de peau des souris immunocompétentes mais comparé aux souris receveuses naïves, aucune tolérance n'a pu être induite. Toutefois, l'ajout d'un traitement anti-LFA-1 (permettant de bloquer la circulation des lymphocytes T activées) a permis d'améliorer de manière significative la survie de la greffe. Cependant, le rejet chronique, dû à la présence de lymphocytes B activés/mémoires et la production d'anticorps donneur-spécifiques, n'a pas pu être évité. Cibler l'activation des lymphocytes T est la stratégie immunothérapeutique prépondérente après une TOS. C'est pourquoi dans la deuxième partie de cette thèse nous nous sommes intéressés au système de signalisation d'un récepteur des lymphocytes T qui dépend de la paracaspase Malti en tant que nouvelle stratégie immunosuppressive pour le contrôle des lymphocytes T alloréactifs. Nous avons montré que bien que l'inhibition de la signalisation du lymphocyte T en aval de Malti induise une tolérance envers un greffon de peau avec incompatibilités antigéniques mineures, cela ne permet cependant qu'une régulation partielle de l'alloréponse contre des antigènes du CMH. Nous nous sommes aussi intéressés spécifiquement à l'activité protéolytique de Malti. L'inhibition constitutive de l'activité protéolytique de Malti chez les souris Malti-ki s'est révélée délétère pour l'induction de la tolérance car elle diminue la fonction des Treg et augmente l'alloréactivité des cellules Thl. Cependant, lors de l'utilisation d'un inhibiteur peptidique de l'activité protéase de Malti in vitro, il a été possible d'observer une atténuation de l'alloéactivité des lymphocytes T ainsi qu'un maintien de la population des Treg existants. Ces résultats nous laissent penser que des études plus poussées sur le rôle de la signalisation médiée par Malti seraient à envisager dans le domaine de la transplantation. En résumé, les résultats obtenus durant cette thèse nous ont permis d'élucider certains mécanismes immunologiques propres à de nouvelles stratégies thérapeutiques potentielles dont le but est d'induire une tolérance lors de TOS. De plus, ces résultats nous ont permis de souligner l'importance d'utiliser des modèles davantage physiologiques contenant, notamment en tenant compte des lymphocytes B et T mémoires alloréactifs. -- Organ transplantation remains the best available treatment for many forms of end-stage organ diseases, with over 100,000 solid organ transplantations (SOT) occurring worldwide eveiy year. Although the available immunosuppressive (IS) drugs are efficient in controlling acute immune activation and graft rejection, the off-target side effects as well as long-term graft and patient survival remain a challenge in the clinic. Hence, innovative therapeutic approaches are needed to improve long-term outcome across immunological barriers. Based on extensive experimental data obtained over the last decade, it is tempting to consider immunotherapy using Treg; the natural suppressors of overt inflammatory responses, in promoting transplantation tolerance. The first hurdle for the therapeutic use of Treg is their insufficient numbers in non- manipulated individuals, in particular when facing strong immune activation and expanding alloreactive effector cells. Because of the limitations associated with current protocols aiming at ex-vivo expansion or in vitro induction of Treg, the aim of the first part of this thesis was to determine the efficacy of direct in vivo expansion of Treg using the IL-2/JES6- 1 immune complex (IL2c). We found that whilst IL2c mediated Treg expansion alone allowed the prolonged graft survival of fìlli MHC-mismatched skin grafts, its combination with short-term CD40L-CD40 co-stimulation blockade (anti-CD 154/MR1) to inhibit T cell activation administered at the time of transplantation was able to achieve long-term robust tolerance. This study also highlighted the importance of combining Treg based therapies with the appropriate co-stimulation blockade as a combination of IL2c and CD28-B7.1/2 co- stimulation blockade (CTLA-4 Ig) only resulted in slight prolongation of graft survival but not tolerance. The translation of tolerance induction therapies modelled in rodents into non-human primates or into clinical trials has seldom been successful. One main reason being the presence of pre-existing memory T- and B-cells due to acquired immunity in humans versus laboratory animals. Hence, we tested whether IL2c+MRl could promote graft survival in pre-sensitized mice. We found that in the presence of alloreactive memory T- and B-cells, IL2c+MRl combination therapy could prolong MHC-mismatched skin graft survival in immunocompetent mice but tolerance was lost compared to the naïve recipients. The addition of anti-LF A-1 treatment, which prevents the trafficking of memory T cells worked synergistically to significantly further enhance graft survival. However, late rejection mediated by activated/memory B cells and persistent donor-specific alloantibodies still occurred. Immunotherapeutic strategies targeting the activation of T cells are the cornerstone in the current immunosuppressive management after SOT. Therefore, in the next part of this thesis we investigated the paracaspase Malti-dependent T-cell receptor signalling as a novel immunosuppressive strategy to control alloreactive T cells in transplantation. We observed that although the inhibition of Malti downstream T signalling lead to tolerance of a minor H- mismatch skin grafts, it was however not sufficient to regulate alloresponses against MHC mismatches and only prolonged graft survival. Furthermore, we investigated the potential of more selectively targeting the protease activity of Malti. Constitutive inhibition of Malti protease activity in Malti-ki mice was detrimental to tolerance induction as it diminished Treg function and increased Thl alloreactivity. However, when using a small peptide inhibitor of Malti proteolytic activity in vitro, we observed an attenuation of alloreactive T cells and sparing of the pre-existing Treg pool. This indicates that further investigation of the role of Malti signalling in the field of transplantation is required. Collectively, the findings of this thesis provide immunological mechanisms underlying novel therapeutic strategies for the promotion of tolerance in SOT. Moreover, we highlight the importance of testing tolerance induction therapies in more physiological models with pre-existing alloreactive memory T and B cells.

Neurology and psychiatry: waking up to opportunities of sleep. : State of the art and clinical/research priorities for the next decade.

In recent years, evidence has emerged for a bidirectional relationship between sleep and neurological and psychiatric disorders. First, sleep-wake disorders (SWDs) are very common and may be the first/main manifestation of underlying neurological and psychiatric disorders. Secondly, SWDs may represent an independent risk factor for neuropsychiatric morbidities. Thirdly, sleep-wake function (SWF) may influence the course and outcome of neurological and psychiatric disorders. This review summarizes the most important research and clinical findings in the fields of neuropsychiatric sleep and circadian research and medicine, and discusses the promise they bear for the next decade. The findings herein summarize discussions conducted in a workshop with 26 European experts in these fields, and formulate specific future priorities for clinical practice and translational research. More generally, the conclusion emerging from this workshop is the recognition of a tremendous opportunity offered by our knowledge of SWF and SWDs that has unfortunately not yet entered as an important key factor in clinical practice, particularly in Europe. Strengthening pre-graduate and postgraduate teaching, creating academic multidisciplinary sleep-wake centres and simplifying diagnostic approaches of SWDs coupled with targeted treatment strategies yield enormous clinical benefits for these diseases.

Mobility Among Social Education Students at the University of Girona: Taking Stock of a Decade of Fieldwork Practice Abroad

The following article is divided into five sections, each one with a specific objective. The first section briefly presents the student mobility experiences obtained basically through the fieldwork practice course in social education studies at the University of Girona. The second section delves more deeply to explore the value of the exchange and the student mobility experience over one semester of intensive fieldwork practice. The third section presents data about the students who have participated in this experience inall ten of the graduating classes. The fourth part offers an assessment of the experience and reports which aspects are considered essential to a good student mobility experience. Finally, various actions to be taken to improve these educational experiences within the social education studies at the University of Girona are specified
