Sex differences in patients receiving anticoagulant therapy for venous thromboembolism.

In patients with venous thromboembolism (VTE), the outcome during the course of anticoagulant therapy may differ according to the patient's sex. We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) database to compare the rate of VTE recurrences, major bleeding, and mortality due to these events according to sex.As of August 2013, 47,499 patients were enrolled in RIETE, of whom 24,280 (51%) were women. Women were older, more likely presented with pulmonary embolism (PE), and were more likely to have recent immobilization but less likely to have cancer than men. During the course of anticoagulation (mean duration: 253 d), 659 patients developed recurrent deep vein thrombosis (DVT), 576 recurrent PE, 1368 bled, and 4506 died. Compared with men, women had a lower rate of DVT recurrences (hazard ratio [HR]: 0.78; 95% confidence interval [CI]: 0.67-0.91), a similar rate of PE recurrences (HR: 0.98; 95% CI: 0.83-1.15), a higher rate of major bleeding (HR: 1.21; 95% CI: 1.09-1.35), and higher mortality due to PE (HR: 1.24; 95% CI: 1.04-1.47). On multivariable analysis, any influence of sex on the risk for recurrent DVT (HR: 0.88; 95% CI: 0.75-1.03), major bleeding (HR: 1.10; 95% CI: 0.98-1.24), or fatal PE (HR: 1.01; 95% CI: 0.84-1.22) was no longer statistically significant.In conclusion, women had fewer DVT recurrences and more bleeds than men during the course of anticoagulation. These differences were not due to sex, but very likely to other patient characteristics more common in female patients and differences in treatment choice.

The role of dentritic cells in leishmania infection : use of novel DC lines for the development of monoclonal antibodies

Les cellules dendritiques (DCs) sont des cellules multifonctionnelles qui font le lien entre le sytème immunitaire inné et adaptatif chez les mammifères. Il existe plusieurs sous-types de DCs basés sur leurs fonctions et l'endroit où elles se situent dans le corps. Dans le cadre de cette thèse, nous avons étudié le rôle de ces cellules face à une infection parasitaire. La Leishmania est un parasite causant une maladie appelée Leishmaniose, maladie endémique de l'Afrique, de l'Asie et de certaines régions de l'Amérique du Sud. Certaines espèces causent des lésions cutanées, alors que d'autres causent des lésions dans les muqueuses ou dans les organes internes. Le système immunitaire répond en générant une réponse inflammatoire qui élimine l'infection. Lors d'une réponse non-inflammatoire (de type cytokines, chemokines), cela va amener à une persistance du parasite sur le long terme. Les DC s'activant en présence du parasite dans la peau, vont le transporter vers un ganglion. A cet endroit, se trouvent différents sous-types de DC qui ont la particularité de présenter l'antigène (spécifique à la Leishmaniose) aux lymphocytes T, ce qui va alors amener à une réponse immunitaire puissante contre le parasite. Nous avons comparé différentes espèces de Leishmaniose dans leur façon d'activer les DC et différents modèles de souris ont été utilisé dans ce but-là. Les souris du type C57BL/6 sont connues pour être résistantes à L. major et sensibles à L. mexicana, alors qu'au contraire, les souris Balb/c sont connues pour être sensibles à ces deux espèces. En utilisant des parasites fluorescents transgéniques, nous avons comparé ces deux espèces de parasites (L. major et L. mexicana) en recherchant quelles cellules elles sont capables d'infecter in-vivo dans un modèle murin. Le rôle général des DC dans une infection à L. major a déjà été décrit. Dans notre étude, nous avons étudié le besoin en DC CD8a+ dans les ganglions afin d'engendrer une réponse face à une infection à L. major. Les souris qui n'ont pas ce sous-type de DC sont beaucoup plus sensibles à l'infection : elles ont des marqueurs inflammatoires plus bas et des lésions plus grandes. Nous avons également remarqué que les DC CD8a+ jouent un rôle crucial dans une phase plus avancée de l'infection. Dans notre laboratoire, nous avons la chance d'avoir une source illimitée de DCs de sous-type CD8a+ provenant d'une souris génétiquement modifiée par nos soin. Grâce à cela, nous avons utilisé ces cellules CD8a+ pour immuniser des rats afin de produire des anticorps monoclonaux ayant des propriétés spécifiques comme l'identification de protéines uniques présentes à la surface des DC et qui ensuite, modulent une réponse immunitaire in-vivo. Nous sommes actuellement en phase de caractérisation de plus de 750 hybridomes générés dans notre laboratoire. - Les cellules dendritiques (DCs) constituent le lien entre le système inné et adaptatif de la réponse immunitaire, car elles sont capables de présenter l'antigène, de donner la co- stimulation et de relâcher des cytokines et chimokines. Au cours de cette thèse, nous avons exploré différentes familles de DC lors d'infections parasitaires, telles que la Leishmaniose, parasite intracellulaire qui infecte les mammifères. La plupart des lésions cutanées résistantes sont caractérisées par une réponse pro-inflammatoire générée par l'IL-12. A l'inverse, pour la forme non résistante, la réponse est générée par l'IL-4 et l'IL-10, dans les modèles murins vulnérables. L'infection avec Lmajor a été caractérisée chez la souris C57BL/6 (Thl) et chez la souris Balb/c (Th2). Chez la souris C57BL/6 la lésion guérit, alors que chez la souris Balb/c, la lésion est au contraire non-cicatrisante. Nous avons comparé l'activation causée dans l'ensemble des DC par différentes espéces de Leishmania, et plus spécifiquement dans les DC CD8a+ présentes dans les ganglions lymphatiques et leur rôle dans la vulnérabilité à L. major. Ces cellules sont spécialisées dans la présentation croisée d'antigènes exogènes par le CMH-I et le haut taux de production d'IL-12 après activation. En utilisant des DC dérivées de moelle osseuse, nous avons constaté que L. guyanensis V+ (transportant un retrovirus) était le plus efficace pour l'activation des DC in-vitro comparé à L. major, L. mexicana et L. guyanensis (V-). Toutefois, in-vivo, les souris infectées avec L. major ont vu la taille de leur ganglions lymphatiques drainants augmentée, 3-6 semaines après l'infection dans les deux espèces de souris (les C57BL/6 résistantes et les Balb/c sensibles). En utilisant un parasite fluorescent transgénique, nous avons trouvé que les souris C57BL/6 sensibles à Lmexicana ont un nombre plus important de cellules Β infectées et un plus petit nombre de DC dérivées des monocytes inflammatoires, comparé au souris infectées avec L. major. Les conséquences de ces observations sont encore à l'étude. Des souris déficientes en CD8ct+DC et CD103+ sont plus sensibles à L. major que les souris WT: leurs lésions sont plus grandes et la charge parasitaire est plus importante. Nous avons généré une chimère de moelles osseuse CD11-DTR et Batf3-/- en mélangeant les moelles de ces deux souris, afin de déterminer le temps après infection où le manque de DC's CD8a+ contribue le plus à l'augmentation de la vulnérabilité chez la souris KO. Ces souris produisent plus d'IgG1 et IgE, font une réponse Th2 plus forte et Thl moins forte. Nous avons constaté que les souris déficientes en DC CD8a+ au début de la réponse immunitaire adaptive (trois semaines après injection) maintiennent un haut taux de lésions de grande taille, semblable à celui des souris chez qui les cellules ont été déplétées avant l'injection. Cela indique que les DC CD8a+ sont nécessaires pour l'efficacité de l'immunité dans la phase chronique de l'infection à L. major. Parallèlement à cela, nous avons aussi commencé une génération d'anticorps monoclonaux dirigés contre les DC CD8a+ activés en utilisant des souches établies dans notre laboratoire. En partant d'une librairie de 763 hybridomes, nous avons identifié plusieurs clones dignes d'intérêt avec une capacité fonctionnelle à moduler la prolifération et la sécrétion de cytokines des cellules T, ainsi que les molécules de co-stimulation présentes à la surface des DC activées elle-même. - Dendritic cells (DCs) are the bridge between the innate and the adaptive arms of the immune systems. They are professional antigen presentation cells and have important cytokine/chemokine release functions. In this dissertation we have focussed on the study of the different subsets of DCs in parasitic infection immunity. Leishmania are intra-cellular parasites of many different species that infect mammals. Most cutaneous lesions that are self- healing are characterized with a pro-inflammatory response with IL-12 while high levels of cytokines such as IL-4 and IL-10 characterized in susceptible mouse models. In mice L. major infection has been well characterized in C57BL/6 mice (Thl) that form healing lesions while Balb/c mice (Th2) form non-healing lesions. This thesis is focussed on comparing DC activation at large by different strains of Leishmania and more specifically, dLN resident CD8a+ DCs and their role in L. major susceptibility. This subset is specialized in cross- presentation of exogenous antigens in the MHC-I pathway and produce high levels of EL-12. Using bone marrow derived DCs we found that L. guyanensis V+ (carrying a retro-virus) was the most efficient at activating DCs in-vitro. In-vivo however L. major infected mice had the largest dLNs 3-6 weeks after infection in both genetically resistant C57BL/6 and susceptible Balb/c mice. Using transgenic fluorescent parasites, we found that C57BL/6 mice which are susceptible to L. mexicana had more number of infected Β cells and fewer number of infected inflammatory monocyte derived DCs in contrast to L. major infection. Using mice deficient in CD8a+ DCs, we found that these mice were more susceptible to L. major than their WT counterparts. They made larger lesions, had higher parasite burdens, higher levels of Th2 indicating immunolgloblins as measured by higher serie IgE levels and lower CD4+ IFNy+ cells. A mixed bone marrow chimera system of CDllc-DTR and Batf3~'~ was generated to determine the time point at which the lack of CD8a+ DCs most contributes to the increased susceptibility in KO mice. We found that mice depleted of CD8a+ DCs at the advent of the adaptive response (3 weeks after infection) maintained the significantly higher lesion size similar to mice whose cells were depleted from the onset of infection. This indicates that CD8a+ DCs are required for effective immunity in the chronic phase of L. major infection. We also began the generation of a valuable tool of monoclonal antibodies against activated CD8a+ DCs using our in-house DC line. From a library of 763 hybridomas we have identified several interesting clones with a functional ability to modulate Τ cell proliferation and cytokine secretion as well as down-modulating co-stimulatory molecules on activated DC cells themselves.

The role of polymerase chain reaction of high-risk human papilloma virus in the screening of high-grade squamous intraepithelial lesions in the anal mucosa of human immunodeficiency virus-positive males having sex with males.

OBJECTIVES To evaluate the advantages of cytology and PCR of high-risk human papilloma virus (PCR HR-HPV) infection in biopsy-derived diagnosis of high-grade squamous intraepithelial lesions (HSIL = AIN2/AIN3) in HIV-positive men having sex with men (MSM). METHODS This is a single-centered study conducted between May 2010 and May 2014 in patients (n = 201, mean age 37 years) recruited from our outpatient clinic. Samples of anal canal mucosa were taken into liquid medium for PCR HPV analysis and for cytology. Anoscopy was performed for histology evaluation. RESULTS Anoscopy showed 33.8% were normal, 47.8% low-grade squamous intraepithelial lesions (LSIL), and 18.4% HSIL; 80.2% had HR-HPV. PCR of HR-HPV had greater sensitivity than did cytology (88.8% vs. 75.7%) in HSIL screening, with similar positive (PPV) and negative predictive value (NPV) of 20.3 vs. 22.9 and 89.7 vs. 88.1, respectively. Combining both tests increased the sensitivity and NPV of HSIL diagnosis to 100%. Correlation of cytology vs. histology was, generally, very low and PCR of HR-HPV vs. histology was non-existent (<0.2) or low (<0.4). Area under the receiver operating characteristics (AUROC) curve analysis of cytology and PCR HR-HPV for the diagnosis of HSIL was poor (<0.6). Multivariate regression analysis showed protective factors against HSIL were: viral suppression (OR: 0.312; 95%CI: 0.099-0.984), and/or syphilis infection (OR: 0.193; 95%CI: 0.045-0.827). HSIL risk was associated with HPV-68 genotype (OR: 20.1; 95%CI: 2.04-197.82). CONCLUSIONS When cytology and PCR HR-HPV findings are normal, the diagnosis of pre-malignant HSIL can be reliably ruled-out in HIV-positive patients. HPV suppression with treatment protects against the appearance of HSIL.

Exhaustion of bacteria-specific CD4 T cells and microbial translocation in common variable immunodeficiency disorders.

In the present study, we have investigated the functional profile of CD4 T cells from patients with common variable immunodeficiency (CVID), including production of cytokines and proliferation in response to bacteria and virus-derived antigens. We show that the functional impairment of CD4 T cells, including the reduced capacity to proliferate and to produce IFN-γ and IL-2, was restricted to bacteria-specific and not virus-specific CD4 T cells. High levels of endotoxins were found in the plasma of patients with CVID, suggesting that CD4 T cell dysfunction might be caused by bacterial translocation. Of note, endotoxemia was associated with significantly higher expression of programmed death 1 (PD-1) on CD4 T cells. The blockade of the PD-1-PD-L1/2 axis in vitro restored CD4 T cell proliferation capacity, thus indicating that PD-1 signaling negatively regulates CD4 T cell functions. Finally, we showed that intravenous immunoglobulin G (IVIG) treatment significantly reduced endotoxemia and the percentage of PD-1(+) CD4 T cells, and restored bacteria-specific CD4 T cell cytokine production and proliferation. In conclusion, the present study demonstrates that the CD4 T cell exhaustion and functional impairment observed in CVID patients is associated with bacterial translocation and that IVIG treatment resolves bacterial translocation and restores CD4 T cell functions.

Role of double-balloon enteroscopy in malignant small bowel tumors.

AIMTo assess the double-balloon enteroscopy (DBE) role in malignant small bowel tumors (MSBT). METHODS This is a retrospective descriptive study performed in a single center. All consecutive patients who underwent a DBE with final diagnosis of a malignant neoplasm from 2004 to 2014 in our referral center were included. Patient demographic and clinical pathological characteristics were recorded and reviewed. MSBT diagnosis was achieved either by DBE directed biopsy with multiple tissue sampling, endoscopic findings or histological analysis of surgical specimen. We have analyzed double-balloon enteroscopy impact in outcome and clinical course of these patients. RESULTS Of 627 patients, 28 (4.5%) (mean age = 60 ± 17.3 years) underwent 30 procedures (25 anterograde, 5 retrograde) and were diagnosed of a malignant tumor. Patients presented with obscure gastrointestinal bleeding (n = 19, 67.9%), occlusion syndrome (n = 7, 25%) and diarrhea (n = 1, 3.6%). They were diagnosed by DBE biopsy (n = 18, 64.3%), histological analysis of surgical specimen (n = 7, 25%) and unequivocal endoscopic findings (n = 2, 7.1%). Gastrointestinal stromal tumor (n = 8, 28.6%), adenocarcinoma (n = 7, 25%), lymphoma (n = 4, 14.3%), neuroendocrine tumor (n = 4, 14.3%), metastatic (n = 3, 10.7%) and Kaposi sarcoma (n = 1, 3.6%) were identified. DBE modified outcome in 7 cases (25%), delaying or avoiding emergency surgery (n = 3), modifying surgery approach (n = 2) and indicating emergency SB partial resection instead of elective approach (n = 2). CONCLUSION DBE may be critical in the management of MSBT providing additional information that may be decisive in the clinical course of these patients.

Neurologie [News in neurology 2013].

In 2013, perampanel is approved as an add-on treatment for generalised and focal seizures in pharmaco-resistant epilepsy. New anticoagulants are superior to antivitamin K in stroke secondary prevention in case of atrial fibrillation. DBS remains a valid therapeutic option for advanced Parkinson's disease. Intranasal ketamine seems to reduce the intensity of severe migraine aura. High concentrations of topic capsaicin improve post-herpetic neuralgia. In Alzheimer's disease, statins might deteriorate cognitive functions. Oral immuno-modifing treatments for relapsing remitting multiple sclerosis have shown to slow cerebral atrophy progression at two years.

Confounding factors and genetic polymorphism in the evaluation of individual steroid profiling

In the fight against doping, steroid profiling is a powerful tool to detect drug misuse with endogenous anabolic androgenic steroids. To establish sensitive and reliable models, the factors influencing profiling should be recognised. We performed an extensive literature review of the multiple factors that could influence the quantitative levels and ratios of endogenous steroids in urine matrix. For a comprehensive and scientific evaluation of the urinary steroid profile, it is necessary to define the target analytes as well as testosterone metabolism. The two main confounding factors, that is, endogenous and exogenous factors, are detailed to show the complex process of quantifying the steroid profile within WADA-accredited laboratories. Technical aspects are also discussed as they could have a significant impact on the steroid profile, and thus the steroid module of the athlete biological passport (ABP). The different factors impacting the major components of the steroid profile must be understood to ensure scientifically sound interpretation through the Bayesian model of the ABP. Not only should the statistical data be considered but also the experts in the field must be consulted for successful implementation of the steroidal module.

Coordination pattern variability provides functional adaptations to constraints in swimming performance.

In a biophysical approach to the study of swimming performance (blending biomechanics and bioenergetics), inter-limb coordination is typically considered and analysed to improve propulsion and propelling efficiency. In this approach, 'opposition' or 'continuous' patterns of inter-limb coordination, where continuity between propulsive actions occurs, are promoted in the acquisition of expertise. Indeed a 'continuous' pattern theoretically minimizes intra-cyclic speed variations of the centre of mass. Consequently, it may also minimize the energy cost of locomotion. However, in skilled swimming performance there is a need to strike a delicate balance between inter-limb coordination pattern stability and variability, suggesting the absence of an 'ideal' pattern of coordination toward which all swimmers must converge or seek to imitate. Instead, an ecological dynamics framework advocates that there is an intertwined relationship between the specific intentions, perceptions and actions of individual swimmers, which constrains this relationship between coordination pattern stability and variability. This perspective explains how behaviours emerge from a set of interacting constraints, which each swimmer has to satisfy in order to achieve specific task performance goals and produce particular task outcomes. This overview updates understanding on inter-limb coordination in swimming to analyse the relationship between coordination variability and stability in relation to interacting constraints (related to task, environment and organism) that swimmers may encounter during training and performance.

Range-Wide Sex-Chromosome Sequence Similarity Supports Occasional XY Recombination in European Tree Frogs (Hyla arborea).

In contrast with mammals and birds, most poikilothermic vertebrates feature structurally undifferentiated sex chromosomes, which may result either from frequent turnovers, or from occasional events of XY recombination. The latter mechanism was recently suggested to be responsible for sex-chromosome homomorphy in European tree frogs (Hyla arborea). However, no single case of male recombination has been identified in large-scale laboratory crosses, and populations from NW Europe consistently display sex-specific allelic frequencies with male-diagnostic alleles, suggesting the absence of recombination in their recent history. To address this apparent paradox, we extended the phylogeographic scope of investigations, by analyzing the sequences of three sex-linked markers throughout the whole species distribution. Refugial populations (southern Balkans and Adriatic coast) show a mix of X and Y alleles in haplotypic networks, and no more within-individual pairwise nucleotide differences in males than in females, testifying to recurrent XY recombination. In contrast, populations of NW Europe, which originated from a recent postglacial expansion, show a clear pattern of XY differentiation; the X and Y gametologs of the sex-linked gene Med15 present different alleles, likely fixed by drift on the front wave of expansions, and kept differentiated since. Our results support the view that sex-chromosome homomorphy in H. arborea is maintained by occasional or historical events of recombination; whether the frequency of these events indeed differs between populations remains to be clarified.

Rhumatologie. Une nouvelle option thérapeutique dans la prise en charge de l'inflammation chronique en rhumatologie: les inhibiteurs des janus kinases [A new therapeutical option for chronic inflammation in rheumatology: janus kinases inhibitors (JAK)].

In the last 15 years, the therapeutical options for the treatment of chronic inflammatory diseases in rheumatology have increased a lot. Nevertheless, some patients do not respond or respond partially to the current therapies--including to the biologics therapy. Tofacitinib (Xeljanz) is now on the Swiss market. It inhibits the JAK pathway. Tofacitinib--as monotherapy or with methotrexate--improves the control of rheumatoid arthritis (RA). In a comparative study, tofacitinib was as effective as adalimumab. Further, tofacitinib reduced structural damages in RA and is considered as an alternative, in case of non-response, to anti-TNF and probably to other biologics therapy. The side effects are upper respiratory tract and opportunist infections and tuberculosis. Blood count, lipids, kidney function, liver tests, CK and blood pressure have to be monitored.

Geographic variation in sex-chromosome differentiation in the common frog (Rana temporaria).

In sharp contrast with birds and mammals, sex-determination systems in ectothermic vertebrates are often highly dynamic and sometimes multifactorial. Both environmental and genetic effects have been documented in common frogs (Rana temporaria). One genetic linkage group, mapping to the largest pair of chromosomes and harbouring the candidate sex-determining gene Dmrt1, associates with sex in several populations throughout Europe, but association varies both within and among populations. Here, we show that sex association at this linkage group differs among populations along a 1500-km transect across Sweden. Genetic differentiation between sexes is strongest (FST  = 0.152) in a northern-boreal population, where male-specific alleles and heterozygote excesses (FIS  = -0.418 in males, +0.025 in females) testify to a male-heterogametic system and lack of X-Y recombination. In the southernmost population (nemoral climate), in contrast, sexes share the same alleles at the same frequencies (FST  = 0.007 between sexes), suggesting unrestricted recombination. Other populations show intermediate levels of sex differentiation, with males falling in two categories: some cluster with females, while others display male-specific Y haplotypes. This polymorphism may result from differences between populations in the patterns of X-Y recombination, co-option of an alternative sex-chromosome pair, or a mixed sex-determination system where maleness is controlled either by genes or by environment depending on populations or families. We propose approaches to test among these alternative models, to disentangle the effects of climate and phylogeography on the latitudinal trend, and to sort out how this polymorphism relates to the 'sexual races' described in common frogs in the 1930s.

Ultrahigh dose-rate FLASH irradiation increases the differential response between normal and tumor tissue in mice.

In vitro studies suggested that sub-millisecond pulses of radiation elicit less genomic instability than continuous, protracted irradiation at the same total dose. To determine the potential of ultrahigh dose-rate irradiation in radiotherapy, we investigated lung fibrogenesis in C57BL/6J mice exposed either to short pulses (≤ 500 ms) of radiation delivered at ultrahigh dose rate (≥ 40 Gy/s, FLASH) or to conventional dose-rate irradiation (≤ 0.03 Gy/s, CONV) in single doses. The growth of human HBCx-12A and HEp-2 tumor xenografts in nude mice and syngeneic TC-1 Luc(+) orthotopic lung tumors in C57BL/6J mice was monitored under similar radiation conditions. CONV (15 Gy) triggered lung fibrosis associated with activation of the TGF-β (transforming growth factor-β) cascade, whereas no complications developed after doses of FLASH below 20 Gy for more than 36 weeks after irradiation. FLASH irradiation also spared normal smooth muscle and epithelial cells from acute radiation-induced apoptosis, which could be reinduced by administration of systemic TNF-α (tumor necrosis factor-α) before irradiation. In contrast, FLASH was as efficient as CONV in the repression of tumor growth. Together, these results suggest that FLASH radiotherapy might allow complete eradication of lung tumors and reduce the occurrence and severity of early and late complications affecting normal tissue.

The influence of quality of life in treatment adherence of diabetic patients: a systematic review

AbstractOBJECTIVETo verify the influence of quality of life in treatment adherence of patients with diabetes mellitus.METHODSystematic review of the literature using the databases MEDLINE, CINAHL, Scopus, LILACS, SciELO and Web of Science with studies published between 2003 and 2014 in English, Portuguese or Spanish.RESULTSSix studies were included in the review, three were identified as having better quality of life scores, being related to better adherence to diabetes treatment measured by glycated hemoglobin or characteristics related to diet, exercise, use of medication and foot care. No association was found between quality of life and adherence in two investigations and a study found a negative association between these variables.CONCLUSIONThere is causal relationship between quality of life and adherence with diabetes treatment. It is suggested that psychosocial aspects of patients should be considered by health professionals in the search for better clinical outcomes in diabetes care.
