I'm Not Who I Thought I Was: A Contextual Resolution to the Identity Loss of Combat PTSD.

Given the historical rates of combat post-traumatic stress disorder (PTSD), one can expect 30% of soldiers returning from current military conflicts to suffer from PTSD. For these individuals, various cognitive behavioral therapies (CBT) are the most commonly employed treatments. Unfortunately, however, symptom relapse can be expected with the various CBT approaches, as traumatic memories remain. Soldiers are imbued with a militarized identity, and the identity loss experienced by those soldiers who suffer from PTSD is particularly painful for this population, as the militarized identity effectively disavows personal suffering. For this reason, many combat veterans diagnosed with post-traumatic stress disorder experience undue, prolonged suffering as they struggle to make sense of the different person they fear they have become. This paper contrasts certain versions of Western philosophy, which view the self as a fixed and reified entity with certain versions of Eastern philosophy, which view the self as more contextual and fluid, in order to illuminate the value of employing third wave behavioral treatments, specifically Acceptance and Commitment Therapy (ACT), to treat the identity loss experienced by military veterans with PTSD. ACT echoes the Buddhist principle that attachment to verbally-constructed conceptual notions of self contribute to undue suffering, and that more vital living can be achieved by assuming a more contextual and experiential perspective on identity. Research and anecdotal accounts are cited to illustrate why treatment for identity loss associated with combat PTSD should be less focused on reconstructing a historically substance-oriented self and more focused on an epistemological reorientation to a deconstructed, contextual self.

From The Holding Cell to the Holding Environment: Applying an Intersubjective Approach into Trauma Treatment with Women in the Correctional Setting

Abstract This paper investigates themes and parallels related to the traumatic experiences women face within the correctional setting and how these experiences influence women's behavior choices that increase their risk of recidivism. Intersubjective Systems Theory is used to conceptualize the distinct dynamics and impact of trauma with this particular population. Intersubjectivity also informs the changes needed to create an environment that would help women in correctional settings to heal, avoid recidivism, and foster successful community reintegration. Principles from Intersubjective Systems Theory are reviewed in this paper to demonstrate: (a) how developmental trauma impacts the lives of incarcerated women, (b) how these women's attempts at self-healing are often maladaptive and lead to arrests, (c) how the current climate in corrections leads to retraumatization and promotes later recidivism, and (d) what changes in the corrections system would promote optimal healing and better outcomes for incarcerated women. Improved outcomes are defined as healthy boundaries, empowerment in choice of relationships, improvement of social support and occupational skills, and reduction of relapse and recidivism.

Rôles de la protéine tyrosine phosphatase DEP-1 dans l'angiogenèse, la perméabilité vasculaire et la progression tumorale

L’angiogenèse et l’augmentation de la perméabilité vasculaire sont des éléments clés pour la croissance et la progression tumorale. Par conséquent, de nombreux efforts sont déployés à comprendre les mécanismes moléculaires impliqués dans la formation et le remodelage des vaisseaux sanguins de manière à identifier de nouvelles cibles thérapeutiques potentielles. De cette optique, les travaux de cette thèse se sont concentrés sur la protéine tyrosine phosphatase DEP-1, initialement identifiée comme un régulateur négatif de la prolifération et de la phosphorylation du VEGFR2 lorsque fortement exprimée dans les cellules endothéliales. Toutefois, en utilisant une approche d’ARNi, il a été démontré que via sa capacité à déphosphoryler la tyrosine inhibitrice de Src (Y529), DEP-1 était également un régulateur positif de l’activation de Src dans les cellules endothéliales stimulées au VEGF. Puisque Src joue un rôle central dans la promotion de l’angiogenèse et la perméabilité vasculaire, nous avons en plus démontré que DEP-1 était un promoteur de ces fonctions in vitro et que la tyrosine phosphorylation de sa queue C-terminale, permettant l’interaction et l’activation de Src, était requise. Les travaux de recherche présentés dans cette thèse démontrent dans un premier temps à partir d’une souris Dep1 KO, dont le développement ne présente aucun phénotype apparent, que la perte de l’expression de DEP-1 se traduit en une inhibition de l’activation de Src et de l’un de ses substrats, la VE-Cadherine, en réponse au VEGF chez la souris adulte. Nos résultats démontrent donc, pour la première fois, le rôle primordial de DEP-1 dans l’induction de la perméabilité vasculaire et de la formation de capillaires in vivo. Conséquemment, la croissance tumorale et la formation de métastases aux poumons sont réduites due à une inhibition de leur vascularisation ce qui se traduit par une diminution de la prolifération et une augmentation de l’apoptose des cellules cancéreuses. De façon intéressante, l’expression élevée de DEP-1 dans les vaisseaux sanguins tumoraux de patientes atteintes du cancer du sein corrèle avec une vascularisation accrue de la tumeur. En plus du rôle de DEP-1 dans la réponse angiogénqiue à l’âge adulte, nos travaux ont également démontré le rôle important de DEP-1 lors de la vascularisation de la rétine, un modèle in vivo d’angiogenèse développementale. Dans ce contexte, DEP-1 inhibe la prolifération des cellules endothéliales et limite leur bourgeonnement et la complexification du réseau vasculaire rétinien en permettant l’expression adéquate du Dll4, un régulateur crucial de l’organisation de la vascularisation développementale. Cette expression du Dll4 découlerait de la stabilisation de la β-caténine par l’inactivation de la GSK3β, un régulateur important de la dégradation de la β-caténine, en réponse au VEGF selon la voie de signalisation VEGFR2-Src-PI3K-Akt-GSK3β. Ainsi, ces travaux identifient DEP-1 comme un régulateur important de l’organisation vasculaire rétinienne. Les rôles positifs de DEP-1 dans les cellules endothéliales découlent principalement de sa capacité à lier et activer la kinase Src. En plus de contribuer à la réponse angiogénique, Src est également un oncogène bien caractérisé notamment pour sa contribution au programme invasif des cellules cancéreuses mammaires. Les travaux de cette thèse illustrent que DEP-1 est préférentiellement exprimée dans les cellules cancéreuses mammaires invasives et qu’il régule l’activation de Src, de voies de signalisation invasives et, par le fait même, de l’invasivité de ces cellules in vitro et in vivo. De façon intéressante, ces observations corrèlent avec des données cliniques où l’expression modérée de DEP-1 est associée à un mauvais pronostic de survie et de rechute. Ces résultats démontrent donc, pour la première fois, le rôle positif de DEP-1 dans l’activation de Src au niveau des cellules endothéliales et des cellules cancéreuses mammaires ce qui permet la régulation du bourgeonnement endothélial, de la perméabilité vasculaire, de l’angiogenèse normale et pathologique en plus de l’invasion tumorale.

Les oncogènes NUP98-PHF23 et NUP98-HOXD13 confèrent un potentiel aberrant d’auto-renouvellement aux progéniteurs thymiques

L’initiation de la leucémogénèse dans la leucémie aigue lymphoblastique (LAL)-T résulte de l’activation aberrante de facteurs de transcription de la lignée lymphocytaire T. Nous démontrons que les gènes de fusion NUP98-PHF23 (NP23) et NUP98-HOXD13 (NHD13) reprogramment les thymocytes normaux en cellules souches pré-leucémiques (CS-préL) possédant un potentiel aberrant d’auto-renouvellement. Basé sur des essais de clonalité performés sur des thymocytes transplantés en série, nous avons découvert que cette population est hiérarchisée similairement aux cellules souches hématopoïétiques normales. Ces CS-préL dévoilent un enrichissement du compartiment de précurseurs thymiques immatures KIT+ où les deux oncogènes, NP23 et NHD13, activent des gènes impliqués dans l’autorenouvellement, incluant Hoxa9, Hoxa10, Lyl1 et Hhex. De plus, l’activité d’autorenouvellement est abrogée par les ARN interférents contre Lyl1 et Hhex, indiquant leur implication fonctionnelle en aval de NP23 et NHD13. Puisque ces gènes sont aussi activés en aval de trois autres oncogènes dans la LAL-T, SCL/TAL1, LMO1 et LMO2, nous concluons que les niveaux d’activation de Lyl1 et Hhex fixent le seuil de reprogrammation des thymocytes normaux en CS-préL. Malgré l'efficacité des traitements de chimiothérapie actuels à diminuer la masse tumorale, les CS-préL sont épargnées, pouvant mener à des rechutes. Nos résultats répondent à ce besoin et proposent de nouvelles avenues permettant de cibler les CS-préL du compartiment de thymocytes immatures dans la LAL-T.

Epstein-Barr virus-associated Hodgkin's lymphoma

Survivors of Hodgkin's lymphoma (HL) frequently have many years to experience the long-term toxicities of combined modality therapies. Also, a significant proportion of HL patients will relapse or have refractory disease, and less than half of these patients will respond to current salvage strategies. 30–50% of HL cases are Epstein–Barr virus associated (EBV-positive HL). The virus is localized to the malignant cells and is clonal. EBV-positive HL is more frequent in childhood, in older adults (>45 years) and in mixed cellularity cases. The survival of EBV-positive HL in the elderly and the immunosuppressed is particularly poor. Despite improvements in our understanding of EBV-positive HL, the true contribution of EBV to the pathogenesis of HL remains unknown. Increased knowledge of the virus’ role in the basic biology of HL may generate novel therapeutic strategies for EBV-positive HL and the presence of EBV-latent antigens in the malignant HL cells may represent a target for cellular immunotherapy.

Changes in smoking behaviour among young women over life stage transitions

Objective: To examine changes in smoking behaviour among young women over four life stages: leaving home; employment or attending college or university; marriage; and parenthood. Methods: Young women participating in the Australian Longitudinal Study on Women's Health completed postal questionnaires in 1996 and 2000. Results: Unmarried women who moved out of their parents' home between 1996 and 2000 had higher odds of adopting smoking than those who had not lived with their parents at either time (OR 1.8, 95% Cl 1.2-2.6). Married women had lower odds of resuming smoking after quitting (OR 0.4, 95% Cl 0.2-0.7) than unmarried women. Women who were pregnant in 2000 had higher odds of quitting smoking (OR 3.8, 95% Cl 2.5-5.6) and women who were pregnant in 1996 and not in 2000 had higher odds of starting to smoke again (OR 3.2, 95% Cl 1.6-6.2) than women who were not pregnant. The odds of being a current smoker or adopting smoking were significantly greater for women who binge drank alcohol or used cannabis and other illicit drugs. Conclusions: Adoption, maintenance and cessation of smoking among young women is strongly related to major life stage transitions, illicit drug use and alcohol consumption. Implications: Life changes such as marriage and actual or contemplated pregnancy provide opportunities for targeted interventions to help women quit smoking and not relapse after having a baby. Legislation to control smoking on licensed premises would reduce the social pressure on women to smoke.

The burden of major depression avoidable by longer-term treatment strategies

Background: Major depression is the largest single cause of nonfatal disease burden in Australia. Effective drug and psychological treatments exist, yet are underused. Objective: To quantify the burden of disease currently averted in people seeking care for major depression and the amount of disease burden that could be averted in these people under optimal episodic and maintenance treatment strategies. Design: Modeling impact of current and optimal treatment strategies based on secondary analysis of mental health survey data, studies of the natural history of major depression, and meta-analyses of effectiveness data. Monte Carlo simulation of uncertainty in the model. Setting: The cohort of Australian adults experiencing an episode of major depression in 2000 are modeled through "what if" scenarios of no treatment, current treatment, and optimal treatment strategies with cognitive behavioral therapy or antidepressant drug treatment. Main Outcome Measure: Disability-Adjusted Life Year. Results: Current episodic treatment averts 9% (95% uncertainty interval, 6%-12%) of the disease burden of major depression in Australian adults. Optimal episodic treatment with cognitive behavioral therapy could avert 28% (95% uncertainty interval, 19%-39%) of this disease burden, and with drugs 24% (95% uncertainty interval, 19%-30%) could be averted. During the 5 years after an episode of major depression, current episodic treatment patterns would avert 13% (95% uncertainty interval, 10%-17%) of Disability-Adjusted Life Years, whereas maintenance drug treatment could avert 50% (95% uncertainty interval, 40%-60%) and maintenance cognitive behavioral therapy could avert 52% (95% uncertainty interval, 42%-64%), even if adherence of around 60% is taken into account. Conclusions: Longer-term maintenance drug or psychological treatment strategies are required to make significant inroads into the large disease burden associated with major depression in the Australian population.

Ethical issues in using a cocaine vaccine to treat and prevent cocaine abuse and dependence

A cocaine vaccine'' is a promising immunotherapeutic approach to treating cocaine dependence which induces the immune system to form antibodies that prevent cocaine from crossing the blood brain barrier to act on receptor sites in the brain. Studies in rats show that cocaine antibodies block cocaine from reaching the brain and prevent the reinstatement of cocaine self administration. A successful phase 1 trial of a human cocaine vaccine has been reported. The most promising application of a cocaine vaccine is to prevent relapse to dependence in abstinent users who voluntarily enter treatment. Any use of a vaccine to treat cocaine addicts under legal coercion raises major ethical issues. If this is done at all, it should be carefully trialled first, and only after considerable clinical experience has been obtained in using the vaccine to treat voluntary patients. There will need to be an informed community debate about what role, if any, a cocaine vaccine may have as a way of preventing cocaine addiction in children and adolescents.
