Full textThe aim of this study was to evaluate cognitive and motor performances of preterm children (24-36 weeks of gestation) aged 9 years (N=9; mean age: 9.41(0.65) years) and to compare them to full term born children’s (N=7; mean age: 9.39(0.62) years) performances. The protocol used, obstacle negotiation while dual tasking, was ecological in nature and represented motor and cognitive challenges that school-aged children face while performing recreational and sporting activities. Three dimentional movement analysis were done in order to quantify cognitive and motor performances. Participants walked under four conditions: unobstructed walking, obstructed walking, walking with Animal-Stroop task, and obstructed walking with Animal-Stroop task. Results demonstrate that the differences in performance between groups increases as the tasks become harder. These results confirm that premature children when facing a complex environment involving both cognitive and motor tasks will show decrements/adjustments in both tasks. This population is able to perform complex tasks but needs to reallocate their attention to focus on the motor requirements of the task in order to succeed.

Full textCette recherche qualitative a pour objectif de comprendre les expériences de violence obstétricales au Québec, à partir des témoignages de femmes ayant participé à un entretien. La violence obstétricale est une forme de violence systémique envers les femmes, vécue dans le cadre des soins entourant la grossesse et l’accouchement. Une analyse de contenu thématique des entretiens relève les principaux thèmes abordés, dont plusieurs se trouvent dans les écrits scientifiques : la déshumanisation et la violence psychologique, la violence physique et sexuelle, les relations avec le personnel soignant, la surmédicalisation de l’enfantement et les contraintes organisationnelles, le non-respect des droits et les répercussions de l’expérience difficile ou négative. Des participantes ont aussi exprimé certaines stratégies d’agentivité s’étant déployées durant leur grossesse et leur accouchement et certaines ont nommé des expériences positives s’étant produites parallèlement aux difficultés rencontrées. L’analyse intersectionnelle des résultats suggère que les expériences de violence obstétricale prennent place sur les plans structurels, disciplinaires, hégémoniques, interpersonnels et expérientiels. Les formations sociales soulevées par les femmes rencontrées (orientation sexuelle, langue parlée, nationalité et origine socioculturelle) ont démontré que le fait de se trouver à l’intersection de plusieurs formes d’oppression rend les expériences uniques pour chaque femme ou groupe de femmes. Il parait ainsi important de s’intéresser aux personnes pouvant se trouver dans toutes les intersections pouvant se juxtaposer à l’oppression de sexe dans l’étude de la violence obstétricale. L’évaluation de la prévalence de cette forme de violence et des pistes d’action devraient être envisagées rapidement par les différents acteurs concernés.
The objective of this qualitative study is to understand experiences of obstetric violence in Quebec, through a series of first-hand accounts from women who participated in an interview process. Obstetric violence is a form of systemic violence against women, experienced in the context of healthcare services related to pregnancy and childbirth. An analysis of the thematic content of the interviews reveals the following primary themes, several of which also appear in scientific articles: dehumanization and psychological violence, physical and sexual violence, relationships to caregivers, the over-medicalization of childbirth and organizational constraints, lack of respect for individual rights and the difficult or negative effects of the experience. Some participants also expressed strategies used to gain agency during pregnancy and childbirth and some named positive experiences that occurred in parallel with the difficulties they encountered. Intersectional analysis of the results suggests that experiences of obstetric violence take place on structural, disciplinary, hegemonic, interpersonal and experiential levels. The forms of socialization brought up by the women interviewed (sexual orientation, language, nationality and sociocultural background) showed that being at the intersection of several forms of oppression makes the experience unique for each woman or group of women. It therefore seems important, in studying obstetric violence, to take a specific interest in mothers who may find themselves at any intersection that may be juxtaposed with gendered oppression. Assessment of the prevalence of this type of violence and potential courses of action should be considered quickly by the different actors concerned.

Full textDental implants are now widely used to replace missing teeth in partially or fully edentulous patients. Several risk factors associated to peri-implant diseases are now recognized such as poor oral health or smoking habits. However there is no consensus on several systemic factors that may interfere with gaining or maintaining osteointegration. The objective of this study was to systematically review the survival of implants and radiographic marginal bone loss around those implants in patients that have bone diseases or conditions that affect bone metabolism. A literature search of different databases was conducted for studies published between January 1990 and December 2019. The systematic review and meta-analysis were done according to the guidelines recommended by the "Preferred Reporting Items for Systematic Review and Meta-Analyses statement". Following the established inclusion and exclusion criteria, we selected six published articles on diabetic patients with 661 implants in total and two published studies on osteoporotic patients with 274 implants in total. In the diabetic population, peri-implant parameters were generally worse particularly when their diabetes was not controlled. Four of the studies were included in the meta-analysis. There was less bone loss in the non-diabetic population (mean difference 0.46 mm; 95% confidence interval (0.06-0.86), z=2.28, p=0.02) as compared to patients that have poorly controlled diabetes. There was no difference in implant survival rates in the two studied populations. As for osteoporotic patients there was no difference in implant survival or marginal bone loss when compared to healthy patients. This systematic review and meta-analysis showed that uncontrolled diabetic patients need to be treated with caution. No conclusions were drawn on any other bone diseases and conditions. More long-term studies are needed to establish guidelines to provide better patient care in the presence of systemic disease.

Full textImmunization is an important and very effective tool in the prevention of diseases. However, for immunization to be fully effective, each individual must receive all the vaccine doses needed to establish and maintain a protective immunity. People who have had a previous adverse event following immunization (AEFI) are sometimes inclined to stop or delay their vaccination series by fear of a potentially more severe recurrence of the AEFI if they receive the next doses of vaccine. When managing these patients, physicians should evaluate the AEFI and determine if it is safe for the patient to receive the next doses of vaccine. This last step is often difficult because most vaccine safety studies describe AEFI frequency in the general population but rarely report their risk of recurrence and the factors influencing these recurrences. The objective of this thesis was to assess the risk of AEFI recurrence and to identify the factors influencing it. To meet this objective, four studies were conducted: 1) Study 1 is a systematic review with meta-analysis that synthesized the available literature on the risk of AEFI recurrence. 2) Study 2 is a retrospective analysis aimed at estimating the risk of AEFI recurrence using the data collected by the Quebec passive surveillance system between 1998 and 2016. 3) Study 3 is a retrospective analysis of medical records that aimed at estimating the risk of recurrence of allergic-like AEFIs and comparing the management of patients who had an allergic-like AEFI with the practice guidelines of the Joint Task Force on Practice Parameters (JTFPP), a group of American experts. 4) Study 4 was a secondary analysis of reactogenicity data collected in three European randomized controlled clinical trials conducted between 2004 and 2010 among 5026 children aged less than 2 years. The purpose of this study was to estimate the risk of AEFI recurrence and the interaction resulting from the co-administration of the 4-component meningococcal serogroup B vaccine (4CMenB, Bexsero ™, GSK) and routine vaccines on the occurrence, recurrence and severity of AEFIs. This work has shown that to date, very few studies have evaluated the risk of AEFI recurrence. Re-immunization is safe in most patients with mild or moderate AEFIs. For patients with serious AEFIs, the data appear to be in the same direction but are less robust as these patients were less often re-immunized. Most allergic-like AEFIs are not suggestive of anaphylaxis but are treated as if they were. The JTFPP definition of anaphylaxis is nonspecific and may require revision. Limiting precautions (skin tests and revaccination in graduated doses) to patients who have had an allergic-like AEFI starting ≤ 1 hour following vaccination (compatible with an IgE-mediated reaction) and those meeting the specific criteria of anaphylaxis (whatever their delay of onset) seems sufficiently sensitive and careful to prevent anaphylaxis during re-immunization. Compared to separate visits, co-administration of 4CMenB and routine vaccines reduces the risk of AEFI from 4% to 49% (negative interaction) depending on the AEFI with a greater reduction in children who have had an AEFI at previous immunizations. Compared to children without a history of AEFI, children who have had a previous AEFI are at higher risk of presenting the same AEFI at subsequent immunizations but recurrences are generally not more severe than previous events. In conclusion, the majority of people who have had an AEFI during previous immunization(s) can be safely re-immunized. To provide a robust scientific basis to clinicians caring for patients with AEFIs, it would be useful for future clinical studies to present not only the overall risk of AEFI but also their risk of recurrence.

Full textThe aim of this work was to study the effects of Epilepsy with Centro-Temporal Spikes (ECTS) on language development, in a population of 27 subjects aged 7 to 16. Our results confirm that the prevalence of language impairment associated with ECTS is significantly greater in this population than in an ordinary one, and our longitudinal study supports the hypothesis of long-term effects. Phonology, morphosyntax and written language were the most impaired domains. Morphosyntactic difficulties, the focus of this thesis, were characterized by an avoidance of structures which syntactic theory identifies as complex in French (3rd person accusative clitics, relative clauses). The subjects also produced more morphosyntactic errors, especially in complex syntactic contexts. These results are compatible with a hypothesis of immaturity or impairment of performance systems. A complementary hypothesis of malfunction of the fronto-temporal network is offered as an avenue to explore

Full textSeveral studies have investigated peri-implantitis complication, but no consensus to date has yet been established. Purpose: The study aims to clarify our understanding of peri-implantitis and to determine the prevalence and causal factors associated with its presence in a cohort of patients at Laval University’s periodontics clinic. Methods: A cross-sectional study was carried out on 86 patients and 258 implants placed between 1999 and 2014. Each patient’s data was completed using their medical and dental records, a pre-established questionnaire, and a clinical and radiological recall examination. Results: The prevalence of patients and implants with peri-implantitis was 15.11% and 6.44%, respectively. The statistically significant factors for peri-implantitis were found to be the dental condition and joint prostheses. Conclusion: Our results show a lower peri-implantitis prevalence than those found in the literature. This confirms that our protocols are well implemented and executed.

Full textCe mémoire porte sur les propriétés fonctionnelles du plancher pelvien à la suite de traitements pour un cancer de l’endomètre. Chez les femmes, le cancer de l’endomètre est le cancer gynécologique ayant la plus forte prévalence. Les traitements oncologiques de ce cancer ont des conséquences néfastes sur la continence urinaire et il est possible que des altérations aux muscles du plancher pelvien à la suite de ces traitements puissent expliquer en partie cette problématique. Ce mémoire est composé de deux études principales. La première étude porte sur la recension des écrits liés aux impacts de la radiothérapie sur la structure anatomique et la fonction musculaire du plancher pelvien chez des adultes atteints d’un cancer pelvien. La deuxième étude compare les propriétés fonctionnelles du plancher pelvien de femmes avec incontinence urinaire à la suite d'un cancer de l'endomètre traité par chirurgie et une radiothérapie adjuvante (groupe à l’étude), à celles de femmes avec hystérectomie sans incontinence (groupe témoin). Cette étude a permis de mettre en évidence une diminution de l’ouverture maximale à l’entrée vaginale, de la longueur vaginale, de la force maximale volontaire du plancher pelvien, du taux de développement de la force dans un test de force maximale et de la coordination lors d’un test de contractions rapides. Ainsi, les deux études de ce mémoire apportent de nouvelles évidences sur les altérations des propriétés fonctionnelles du plancher pelvien à la suite de traitements pour un cancer génital.
This master’s thesis is on functional properties of the pelvic floor muscles after treatments for endometrial cancer. In women, endometrial cancer is the most prevalent gynecological cancer. Urogenital dysfunctions, such as urinary incontinence, are frequent after oncological treatments of this cancer, and it is possible that alterations of the pelvic floor muscles could explain, in parts, such dysfunction. This thesis is constituted of two main studies. The first study is on the systematic review of the literature regarding the documented effects of radiation therapy on the anatomical structure and physiological function of the pelvic floor muscles of adults with pelvic cancer. The second study concerns differences in pelvic floor functional properties of women experiencing urinary incontinence after surgical and radiotherapy treatments for endometrial cancer (study group) to women with hysterectomy for benign disease (comparison group). This study presented results of reduced maximal anterior-posterior opening of the vaginal entry, vaginal length, maximal voluntary contraction, maximal rate of force development in a strength test, and coordination in a speed’s test. These two studies altogether bring new evidence that there are alterations to pelvic floor functional properties following treatments for genital cancer.

Full textLa sténose aortique est la cardiopathie valvulaire la plus fréquente retrouvée chez les patients agés. Suite à l’apparition des symptômes, la survie des patients diminue de façon drastique en l’absence d’un remplacement valvulaire aortique. Cependant, une proportion considérable de ces patients n’est pas opérée en raison d'un risque chirurgical élevé, l'âge étant l'une des principales raisons de refus d’un remplacement valvulaire aortique chirurgical. Ce défaut dans la prise en charge des ces patients a favorisé le développement du remplacement valvulaire aortique par cathéter où implantation valvulaire aortique par cathèter (TAVR ou TAVI), qui a représenté une révolution dans le traitement de la sténose aortique. Cette intervention est actuellement un traitement de routine chez les patients à haut risque chirurgical atteints d’une sténose aortique, même si la chirurgie cardiaque n’est pas contre-indiquée. Ces dernières années ont vu un changement de profil des candidats potentiels vers une population à plus faible risque. Cependant, plusieurs préoccupations demeurent. L’une des plus importantes est la survenue des arythmies et de troubles de conduction, notamment le bloc de branche gauche et le bloc auriculo-ventriculaire, qui sont des complications fréquemment associées au TAVR. Malgré l’évolution de la technologie et le développement de nouveaux dispositifs réduisant le taux global de complications, aucune amélioration n’a pas été intégrée pour prévenir l’apparition de telles complications. De plus, l'utilisation de certains dispositifs de nouvelle génération semble être associée à un risque accru de troubles de conduction, et par conséquent, l'incidence de ces complications pourrait augmenter dans le futur. Cependant, L'impact et l'évolution de ces complications sont inconnus. Ce travail de recherche évalue l'incidence et l'évolution des troubles de conduction suite au TAVR et l'impact des blocs de branche gauche de novo et de l'implantation d'un pacemaker sur les résultats cliniques et échocardiographiques.
The aortic stenosis is one of the most frequent valvular heart diseases, which is mostly diagnosed in older patients. With the symptoms onset, the lifespan of such patients dramatically decrease unless an aortic valve replacement is performed. However, a considerable proportion of such patients do not undergo cardiac surgery owing to a perceived high risk, being the advanced age one of main reasons to deny surgical aortic valve replacement. Such deficiency in the care of these patients has favoured the development of transcatheter aortic valve replacement or implantation (TAVR or TAVI), which has revolutionized the treatment of aortic stenosis. This treatment is now a routine therapy in high-risk patients with aortic stenosis, even if cardiac surgery is not contraindicated. Indeed, the last years have witnessed a shift in the use of this technology to lower risk populations. TAVR technology has experienced a dramatic evolution to integrate enhanced iterations which have allowed, along with the improvement of the technology, a reduction in the risk of complications associated with this therapy. However, several concerns remain. One of them is the occurrence of arrhythmias and conductions disturbances, in particular left bundle branch block and atrioventricular block, which are frequent complications of TAVR. Despite the evolution of the technology and development of new devices leading to a reduction in the overall rate of complications, no new iterations have been integrated to prevent the occurrence of such complications. Moreover, the use of new-generation devices seems to be associated with an increased risk of such complications, and therefore, its incidence is expected to increase in the next future. Nonetheless, little is known about the impact and evolution of these disorders. This thesis evaluates the incidence and evolution of new-onset arrhythmias and conduction abnormalities after TAVR and the impact of new-onset left bundle branch block and permanent pacemaker implantation on late clinical and echocardiographic outcomes.

Full textÀ l’automne 2010, le Québec a réalisé une campagne de vaccination de masse contre la grippe pandémique A(H1N1) en utilisant presque exclusivement un nouveau vaccin adjuvanté à l’AS03 (Arepanrix, GlaxoSmithKline). Les données de surveillance recueillies durant la campagne de vaccination ont montré que le taux de déclaration d’anaphylaxie, une réaction systémique sévère souvent attribuable à l’allergie, s’est avéré être supérieur à celui historiquement observé avec les vaccins contre la grippe saisonnière (8 contre < 1 cas par million de doses, respectivement). De plus, l’évaluation systématique des déclarations de manifestations cliniques inhabituelles (MCI) d’allure allergique a démontré que l’anaphylaxie avait été sous-diagnostiquée parmi les cas déclarés. Plus du deux tiers des MCI d’allure allergique observées durant la campagne de vaccination contre la grippe pandémique sont survenues chez des femmes. En tenant compte du nombre de doses administrées, les femmes avaient un risque deux fois plus élevé que les hommes. De plus, ce risque était plus important durant les années de vie reproductive, soit entre l’âge de 20 et 49 ans. Notre étude cas-témoin appariée a identifié certains facteurs de risque dont l’histoire personnelle et familiale d’allergie, la présence d’une infection respiratoire et la prise de médicaments pour l’asthme dans les jours précédant la vaccination, le statut de travailleur de la santé, et une vaccination dans les 4 premières semaines de campagne. Toutefois, aucun de ces facteurs n’expliquait une grande partie des anaphylaxies ou des MCI d’allure allergique. La présence d’une allergie aux œufs ou au poisson, deux composantes potentiellement allergènes du vaccin, ne s’est pas avéré être un facteur de risque significatif de MCI d’allure allergique. Nous avons aussi réalisé une étude clinique en allergie auprès d’une centaine de cas déclarés durant la campagne de vaccination contre la grippe pandémique qui a montré que peu de ces événements pouvaient être attribuables à une allergie IgE-dépendante au vaccin ou à ses composantes. Cette recherche a mis en évidence le risque plus élevé d’anaphylaxie et de MCI d’allure allergique chez les femmes en âge reproducteur mais n’a pas réussi à identifier d’autres facteurs de risque majeurs. Elle a toutefois démontré que le mécanisme habituellement évoqué pour les expliquer soit la présence d’IgE ciblant une des composantes du vaccin semble jouer un rôle très mineur.

Full textFourteen young adolescents who had previously sustained a mild traumatic brain injury (mTBI) and thirteen healthy adolescents walked in different conditions related to environmental contexts (unobstructed walking (LEVEL), stepping over a narrow obstacle and stepping over a deep obstacle) and simultaneous cognitive tasks (no dual task (NO), Stroop task (St), verbal fluency task and arithmetic task). The goal was to identify the sensitive combinations of locomotor and cognitive tasks as well as variables that would differentiate children in early adolescence with an mTBI from those without. Fluidity was found to be more sensitive than gait speed. Motor dual-task cost (relative change between LEVEL and obstacle crossing with the same cognitive task) was found to differentiate both groups, specifically when involving visual interference (St) and more so when the dynamic equilibrium demand increased with obstacle depth. These results provide direction for future research on clinical assessment using dual-task walking post-mTBI in adolescents.

Full textBariatric surgery has proven beneficial effects on cardiometabolic health, on quality of life and on mortality, but it also seems to negatively influence bone health. Although studies have shown an increase in bone remodeling, a decrease in bone mineral density and histomorphometric alterations suggesting osteomalacia after surgery, few studies have evaluated its impact on fracture risk. Our objectives are to evaluate fracture risk in obese individuals who submitted to bariatric surgery compared with obese and non-obese controls, to evaluate fracture sites in obesity and after bariatric surgery, and to evaluate if the type of surgery influences fracture risk. This study, using healthcare administrative databases, showed that fracture risk increases with the level of obesity, that pattern of fracture changes after surgery, from a pattern associated with obesity before surgery to a pattern typical of osteoporosis post-operatively, and that biliopancreatic diversion is the only type of surgery that was associated with a significant increase in fracture risk in our study.

Full textRadical cystectomy is the reference treatment for muscle invasive bladder cancer. This surgery is associated with a high complication rate and has an important impact on patients’ quality of life. Nutritional status influences outcomes of diseases and surgeries, but few nutritional factors have been associated with complications or mortality after radical cystectomy. We conducted a systematic review to identify factors of the nutritional status associated with the development of complications or mortality after the surgery. This review has shown that hypoalbuminemia seems to be associated with a higher risk of death after the surgery. We conducted a cohort study to identify factors of nutritional status prospectively assessed that predict complications after radical cystectomy, using a standardized reporting method of complications and optimized regression models. Preoperative high body mass index, decreased appetite, weight loss, hypoalbuminemia and hypo-prealbuminemia were associated with complications after RC in this cohort study. Clinical trials are needed to assess surgery issues of preoperative nutritional interventions.

Full textINTRODUCTION: Etomidate is one of the most frequently used anesthetic induction agents for intubating patients with traumatic brain injury (TBI), although the clinical impacts of its adverse effects on adrenal function are debated. Therefore, it is important to assess the consequences of any adrenal suppression that could result from its use in patients with TBI. OBJECTIVE: The primary objective of this study was to determine the risk and the length of relative adrenal insufficiency (RAI) induced by etomidate in patients intubated for moderate and severe TBI. The secondary objective was to determine etomidate’s impact on mortality and morbidity. METHODS: This was a prospective cohort study. Eligible participants were moderate to severe TBI victims aged 16 years and over, intubated and admitted to a tertiary neurosurgical reference center between August 2003 and November 2004. ACTH stimulation tests (250 mcg) were performed on participants 24, 48 and 168 hours after intubation. RAI was defined as an increased of serum cortisol one hour post ACTH (delta cortisol) of less than 248.4 nmol/L (9 mcg/dl). Logistic and linear regression models assessed the association between the exposure to etomidate and the risk of RAI. RESULTS: Of the 94 subjects eligible to participate, 40 underwent ACTH testing. Fifteen subjects received etomidate and 25 received other induction agents. At 24 hours, etomidate did not change the risk of RAI. However, etomidate decreased the delta cortisol (adjusted mean: 305.1 nmol/l, 95% CI [214.7-384.8] vs. 500.5 nmol/l, 95% CI [441.8-565.7], p=0.02). At 48 and 168 hours, this difference disappeared. For all eligible subjects (n=94), there was a non significant trend for increased mortality in the etomidate group (adjusted OR: 4.8, 95% CI [0.6-35.9]). Etomidate was however associated with a significant increased risk of pneumonia (adjusted OR: 3.0, 95% CI [1.0-8.7]; p=0.04). The adjusted length of stay in the intensive care unit was not different (10.2 days for etomidate versus 10.8 days for the other agents). At discharge, the adjusted motor Functional Independence Measure score was significantly lower for subjects in the etomidate group (32 versus 56, p=0.002), but the adjusted cognitive score was not significantly different (35 versus 46, p=0.15). CONCLUSION: Etomidate decreases the adrenal response to an ACTH test up to 24 hours after a single dose used for the intubation of TBI victims. A large randomized controlled trial is needed to further assess its impact on morbidity and mortality.

Full textMore than 1 in 5 patients admitted to a trauma centre in Canada will develop at least one hospital complication, more than three times the proportion observed for general admissions. In accordance with initiatives to improve the quality of care and services related to complications, we proposed 4 quality indicators to reduce hospital complications in trauma. We targeted 4 complications potentially related to quality of care with a high incidence in trauma centres: deep vein thrombosis/pulmonary embolism (DVT/PE), decubitus ulcers, delirium, and pneumonia. Our study was based on a retrospective cohort including 21,124 adults admitted between 2014 and 2018 with moderate or severe trauma to a level I or II trauma center in Quebec. Our indicators were adjusted taking into account the clinical and socio-demographic characteristics of the patients. The derived indicators demonstrated excellent predictive performance and identified 3 hospitals with an incidence of at least one of the targeted complications higher than average. The inter-hospital variations observed were different from one complication to another with intraclass correlation coefficients ranging from 2.4% for pneumonia to 23.4% for DVT/PE. We also proposed algorithms, related to these indicators, to identify patient charts that should be reviewed. The algorithms identified on average 50 and 20 cases of unexpected complications to be reviewed per year for level I and II centers (niveau tertiaire et secondaire régional), respectively. The indicators developed can be used for comparisons among designated centres in a trauma system or for monitoring purposes within specific centres. The identification of unexpected complications will allow the review of cases to identify the reasons for the discrepancies identified by the indicators and propose solutions.

Full textThe very important progress realised in reanimation have really changed the prognosis for life. Now a days, we can see people who wake up after comas witch are longer and longer. More the coma is long, and more the consequences are serious, a prolongation of care is necessary. The institutions are overtake by the rapidity of these medical advances, so the few structures provided for the rehabilitation of the severe injured are unadapted. The research take place in an establishment witch has create, in september 1984, a specific unit to care brain damaged children. After a long period of hospitalization, it's often impossible for them to return to school immediately; they need enough time to adapt themselves to their traumatic situation. The thesis analyses the psycho-intellectual evolution of 15 severe head injured children between 11 and 18 years old, who's coma's period is one month or more. The method mainly clinical is completed by 4 tests (wais, benton, bender, rorschach). After a brain shock so serious, the research underlines the importance of psychic and family traumas. The result of this recent and unique experience in the region is a way to show the necessity of such structures witch allow the children to go perhaps to school again

Full textIn the transplantation field, the morbidity attributable to over-immunosuppression events exceeds that of rejections and no clinical tool diagnoses this condition. Previously, we discovered and validated longitudinally the association between the production of tumor necrosis factor of intermediate monocytes stimulated by peptides of the Epstein-Barr virus and over-immunosuppression.The general hypothesis of my research is that it is possible to develop a test diagnosing overimmunosuppression. Specifically, I studied a prospective unicentric cross-sectional cohort to extrinsically validate the diagnostic values of the test and to study the subpopulations of B lymphocytes for optimization purposes.This cohort of 71 renal transplant recipients exhibits diagnostic values similar to the exploratory cohort, which are a sensitivity and specificity of 83 and 68 % respectively for the predefined diagnostic threshold. This association has been shown to be independent of clinical features, renal function and immunosuppressive regimen. Then, we developed and validated a second diagnostic step with high specificity, based on a threshold of ≤ 19 % of Bm5 and early Bm5 blood lymphocytes, to confirm the diagnosis of overimmunosuppression. In the end, this two-step test classifies two thirds of patients in the overimmunosuppressed or controls category, with positive and negative predictive values of 91 and 89 %, respectively. The adjusted multivariate analysis shows that the risk of overimmunosuppression in patients classified as positive is more than eight times greater than that of controls.In conclusion, my master's project allowed the optimization and validation of a biomarker diagnosing over-immunosuppression in renal transplant patients. A multicenter validation cohort is underway.

Full textL’insuffisance rénale chronique (IRC) est une maladie chronique prévalente et comprenant plusieurs comorbidités. Les complications les plus importantes de l’IRC sont les fractures et la mortalité d’origine cardiovasculaire. Ces dernières ont été regroupées sous l’entité du trouble minéral et osseux en insuffisance rénale chronique (TMO-IRC). La physiopathologie du TMO-IRC revêt un intérêt particulier dans l’optique de mieux comprendre et prévenir les complications des patients IRC. Récemment, les niveaux sanguins de nouveaux marqueurs osseux [sclérostine, dickkopf-related protein 1 (DKK1), fibroblast growth factor 23 (FGF23) et α-klotho], inhibiteurs de la voie de signalisation Wnt, ont été associés à des issues de santé osseuse et vasculaire et pourraient donc jouer un rôle important dans le TMO-IRC. Les objectifs de ce mémoire sont d’investiguer le rôle de ces nouveaux marqueurs osseux dans 1) le TMO-IRC chez les patients greffés et 2) le TMO-IRC chez des patients hémodialysés en lien avec le tissu adipeux de la moelle osseuse (TAM). Les résultats de nos travaux montrent que les marqueurs osseux baissent après la transplantation rénale et suggèrent que l’évolution de la sclérostine et du FGF23 est associée à certains paramètres de rigidité artérielle (vélocité de l’onde de pouls carotidefémorale et vélocité de l’onde de pouls carotide-radiale). De plus, nous avons montré la faisabilité de caractériser le TAM chez une cohorte de dialysés. Nos analyses suggèrent également que le TAM est corrélé de manière inverse avec le DKK1 sérique. Bref, nos résultats suggèrent que ces nouveaux marqueurs osseux pourraient jouer un rôle important dans la physiopathologie du TMO-IRC, et ce, autant chez les patients IRC que les greffés, potentiellement par des mécanismes différents. Une meilleure compréhension des mécanismes d’action de ces marqueurs osseux pourrait ouvrir la voie à une meilleure prise en charge des patients souffrant de TMO-IRC.
Chronic kidney disease – mineral and bone disorders (CKD-MBD) leads to increased comorbidity and mortality due to heightened fractures rate and cardiovascular complications. Understanding the mechanisms of CKD-MBD’s pathophysiology is important in order to eventually propose new therapies that may prevent or treat bone and vascular complications. Recently, circulating levels of new bone markers [sclerostin, dickkopf-related protein 1 (DKK1), fibroblast growth factor 23 (FGF23) and α-klotho], which are Wnt pathway’s inhibitors, have been associated with bone and vascular health outcomes in CKD population and could therefore play an important role in CKD-MBD. The objectives of this master thesis are to investigate the role of these new bone markers 1) in CKD-MBD among kidney transplanted patients and 2) in CKD-MBD among dialysis patients in relation to bone marrow adipose tissue (MAT). Our results show that bone markers lower after kidney transplantation. We observe an association between circulating sclerostin and FGF23 levels evolution and arterial stiffness parameters (carotid-femoral pulse-wave velocity and carotid-radial pulse-wave velocity) after kidney transplant. Moreover, we show the feasibility to characterize MAT in a dialysis cohort and our results suggest an inverse correlation between serum DKK1 levels and MAT. In conclusion, our results show that these new bone markers could play an important role in CKD-MBD both in kidney transplanted and hemodialysis patients likely through different mechanisms. A better understanding of the role of these Wnt inhibitors in CKD-MBD could lead to a better management approach of patients with CKD-MBD.

Full textBariatric surgery is gaining in popularity as a treatment of severe obesity in Quebec and across Canada. While more than one third of patients have type 2 diabetes before bariatric surgery, a large meta-analysis reported type 2 diabetes resolution in 80% of patients after sleeve gastrectomy and Roux-in-Y gastric bypass, and in 95% of patients after biliopancreatic diversion (BPD). However, despite clear health benefits, recent evidence showed that bariatric procedures, especially Roux-in-Y gastric bypass and BPD, are associated with an increased risk of fracture. Assessment of circulating biochemical markers of bone formation and resorption after bariatric surgery could provide insight into the pathophysiology of bone fragility after surgery. More over, several mechanisms have been put forward to explain resolution of type 2 diabetes after bariatric surgery. While preclinical studies have reported that a bone-derived hormone, uncarboxylated osteocalcin (ucOCN), is involved in glucose metabolism, no study has evaluated whether changes in this hormone are associated with improvement in glucose homeostasis after bariatric surgery. Our study aimed at evaluating the early- and medium-term changes in bone remodeling markers after BPD, and whether these changes are associated with changes in whole-body (total) bone mineral density (BMD) and in hormonal factors. Furthermore, we assessed if changes in ucOCN are associated with changes in glucose homeostasis indices after BPD. We used data and frozen plasma samples from a one-year prospective cohort study where blood was drawn at 3 days, 3 months and 12 months after BPD. We showed that BPD is associated with an increase in the bone resorption marker C-telopeptide as early as 3 days after surgery, and that it continued to rise up to one year after surgery, with a greater increase in bone resorption over bone formation markers. Furthermore, a significant decrease in the bone formation marker osteocalcin was seen at 3 days after BPD, which was followed by an increase up to one year after surgery. Moreover, an inverse association between the change in bone resorption marker and the change in total BMD, as well as significant associations between the changes in several bone turnover markersand changes in hormonal factors after BPD were observed. Finally, there was a strong correlation between the increase in ucOCN and the improvement in several indices of glucose homeostasis after BPD, independent of weight loss, suggesting a link between bone and glucose metabolism.

Full textWorldwide it is estimated that 280 000 valve substitutes are implanted each year to replace diseased heart valves. Hence, valve replacement has improved the outcome of patients with valvular heart diseases. The trend over the last decade is towards the use of biological valves or bioprotheses instead of mechanical valves and at the present time, nearly 80% of the implanted valve substitutes are bioprostheses (BPVs). BPVs have a low thrombogenicity, which generally obviates the need for anticoagulation. However, the use of BPVs is still plagued by their limited durability. Structural valve deterioration (SVD) is the major cause of bioprosthetic valve failure expressed clinically by a progressive prosthetic stenosis due to leaflet calcification and/or by regurgitation due to leaflet tear. It is estimated that 20-30% of implanted BPVs will have some degree of dysfunction at 10 years. Thus, SVD is a major hurdle to the widespread utilization of BPVs. Unfortunately, there are currently no effective means by which progression of SVD may be reduced or stopped by the treatment of valve tissues before implantation. However, recent studies suggest that SVD is a complex process probably modulated by several mechanisms including an atherosclerotic-like lipid-mediated inflammation, a calcium deposit induced by a dysfunctional phospho- calcic metabolism and an immune response. Therefore, new directions of research could lead to the development of treatment approaches for the prevention of SVD such as the choice of a specific type of BPV or the initiation of a treatment at the time of valve replacement. Nonetheless, to develop new efficient treatments to avoid BPV failure, it is first required to understand the mechanisms leading to BPV SVD and to identify the factors related to the BPV itself and to the patient clinical and metabolic factors, especially the modifiable ones, that are involved in these processes. The general objective of the study is thus to elucidate the mechanisms implicated in the pathogenesis of structural valve deterioration of aortic bioprostheses and to identify the clinical and metabolic factors that independently determine this pathologic process.

Full textThe aim of the study was to assess the evolution of insomnia during the first four years following a traumatic brain injury (TBI) and to compare between different levels of severity of the TBI. This study also aimed to identify risk factors for different insomnia trajectory (chronic, fluctuating or absence of insomnia). Participants included in this study were adults aged between 18 and 65 years (n=429) and were recruited in a hospital setting and rehabilitation center. They completed several self-reported questionnaires at different time points (4, 8, 12, 24, 36 and 48 months post-TBI) to assess insomnia symptoms (ISI), anxiety and depressive symptoms (HADS) and pain (SF-36). Results showed that prevalence rates of insomnia remained high across assessment times points, varying between 52 and 58%. Symptoms were more prevalent among participants who sustained a mild TBI compared to those with moderate to severe TBI (57% vs 67%) and those symptoms were more severe in the mild compared to the moderate-severe TBI group (ISI mean score: mild TBI= 10.46; moderate-severe TBI = 8.44; F= 14.74, p <.001). One third of individuals who sustained a TBI presented a chronic trajectory of insomnia over the 4-year follow-up period. Those with mild TBI were significantly more represented in the subgroup with a chronic trajectory of insomnia compared to those with moderate-severe TBI (37.7% vs 23.2%, p<.001) Individuals presenting a low level of depressive symptoms paired with moderate anxious symptoms were at greater risk for a chronic course of insomnia symptoms. In conclusion, insomnia is a frequent condition following TBI and may impede recovery and quality of life. Patients with mild TBI and presenting depressive and anxious symptoms following TBI should be followed closely since they have a less favorable prognosis regarding the evolution of their insomnia symptoms.

Full textL’implantation de valve aortique par cathéter (TAVI) a été développée comme une alternative thérapeutique pour les patients avec une sténose aortique sévère et ayant un risque opératoire élevé ou extrême en cas de chirurgie de remplacement valvulaire standard. Par rapport à la chirurgie à cœur ouvert classique, les procédures de TAVI sont moins invasives, parce qu'elles ne sont pas associées au clampage aortique et à la cardioplégie. Toutefois, la procédure implique un certain degré de dommage myocardique dû à la compression du tissu par le ballonnet et la prothèse transcathéter, ainsi que plusieurs courts épisodes d'hypotension extrême et d’ischémie myocardique globale, au cours de la stimulation ventriculaire rapide et du déploiement de la prothèse. De plus, l'approche transapicale, qui est réalisée lorsque l'approche transfémorale n’est pas possible, comprend la ponction de l'apex du ventricule gauche et l'introduction de larges cathéters ce qui augmente vraisemblablement encore les dommages myocardiques. En conséquence, presque tous les patients subissant un TAVI présentent un certain degré de dommage myocardique, défini par une augmentation des enzymes cardiaques, telles que la créatine kinase-MB (CK-MB), la troponine ou le peptide natriurétique de type B (BNP). Néanmoins, les données sur l'incidence exacte des dommages myocardiques, leur étendue, leurs prédicteurs, ainsi que les résultats échocardiographiques et cliniques associés, en fonction des différentes approches et prothèses sont limitées. Les objectifs généraux de mon projet de doctorat sont d'évaluer l'incidence, les facteurs prédictifs et les résultats des dommages myocardiques après TAVI pour le traitement des patients symptomatiques avec sténose aortique sévère ou bioprothèse dysfonctionnelle et à haut risque chirurgical.
Transcatheter aortic valve replacement (TAVR) has emerged as a less invasive therapeutic alternative to surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis at very high-risk or prohibitive perioperative risk. Compared to conventional open-heart surgery, TAVR procedures are less invasive, because they are not associated with aortic cross-clamping and cardioplegia. Even so, the procedure involves some degree of myocardial injury due to tissue compression, caused by the balloon and valve prosthesis, as well as several short episodes of extreme hypotension and global ischemia, during rapid ventricular pacing and valve deployment. Also, the transapical approach, which is an alternative to the transfemoral approach, involves the puncture of the ventricular apex and the introduction of large catheters through it. Accordingly, nearly all patients undergoing TAVR present some degree of myocardial injury, as defined by any increase in cardiac biomarkers, including creatine kinase-MB (CK-MB), troponin or B-type natriuretic peptides (BNP). Nonetheless, data on the exact incidence of myocardial injury, extent, predictors, as well as the associated echocardiographic and clinical outcomes, according to the different type of TAVR procedures and transcatheter valves, have been limited. The general objectives of my PhD project are to evaluate the incidence, predictors and outcomes of myocardial injury following TAVR for the treatment of high-risk patients with severe symptomatic AS or dysfunctional aortic bioprosthesis.

Full textThe first objective of this doctoral thesis was to document anxiety-related disorders and anxiety symptoms 4, 8 and 12 months after mild traumatic brain injury (MTBI), according to premorbid history of anxiety, type of MTBI (complicated or uncomplicated) and premorbid history of MTBI. The second objective was to examine whether the presence of anxiety in the first months after MTBI is associated with more symptoms in different domains in the longer term. Participants were 120 adults with MTBI who were evaluated 4, 8 and 12 months post-accident with the Mini International Neuropsychiatric Interview, the Hospital Anxiety and Depression Scale, and other self-reported questionnaires evaluating fatigue, irritability, perceived stress, cognitive difficulties, depression, insomnia and pain. Results indicated that the frequency of anxiety-related disorders is high in the first 12 months, although there is a significant decrease between 4 and 12 months post-injury. At 4 months post-MTBI, 24% had at least one anxiety-related disorder compared to 11% at 12 months. Individuals with premorbid history of anxiety disorders were significantly more anxious after MTBI compared to those without past history of anxiety. Compared to participants without anxiety, participants with significant anxiety 4 months after MTBI showed more symptoms associated with MTBI at the 12-month assessment.
