Full textA better understanding of the prognosis of dementia could help to provide appropriate care in the disease. At individual level, the need to obtain information on the possible evolution of the disease is caregivers’ prime expectation. At societal level and from a public health point of view, it seems necessary that health policies anticipate needs in care, home care, case managers... The general objective of this thesis was to study the prognosis of dementia to improve the care of patients with Alzheimer's disease or related disorders. We worked from incident cases of dementia of two population-based, long-term cohort studies: Paquid (Personnes Agées QUID) cohort and the Three Cities. First, we studied survival prognosis. Overall, it seems difficult to predict death from only prognostic factors related to dementia. The death in dementia may be linked to dementia itself but also to other factors non-related to dementia and therefore difficult to predict. Secondly, we studied the prognosis of functional abilities. Few literature exists on the functional evolution in dementia. We identified a perfect hierarchy in the sequence of occurrence of total disability in 4 basic activities of daily living: bathing and/or dressing, followed by transferring and/or feeding. From a pragmatic point of view, characterizing the dependency in bathing or dressing is crucial to improve care in dementia. The independent prognosis factors on bathing and dressing disabilities occurrence, adjusted on death risk were: age greater than 80 years at time of diagnosis of dementia, a diagnosis of vascular dementia, disabilities in three or four activities out of the four IADL scale of Lawton and poor or very poor subjective health at time of diagnosis of dementia. Based on this thesis, we have a gained a better knowledge of the evolution of functional abilities in dementia. However, it is difficult to predict the course of the disease; dementia being a multifactorial disease for which there is a very high interindividual variability on the progression of the disease

Full textIntroduction. Complete resection stands as the only curative option for intrahepatic cholangiocarcinoma (IHCC). Still, prognosis remains poor after resection due to a recurrence rate over 60% leading to actual 5-year survival rates below 20%. Reliable prognostic estimation and better understanding of tumor biology would be of interest for improving IHCC prognosis.Methods. Using clinical and biological data from two large cohort of resected IHCC (MSKCC, n=189 and AFC, n=522), three objectives have been explored. First, assessing the performances of different published prognostic models. Second, defining the reliability of preoperative prognostic estimation using imaging, tumoral genomic profiling and circulating tumoral microRNA (miR). Third, evaluating the prognostic impact of perioperative events such as blood transfusion and morbidity.Results. First, nomograms displayed better prognostic accuracy over the AJCC 7th edition staging system. Second, tumor size and multifocality on preoperative imaging allowed patient stratification in groups statistically different regarding prognosis (p<0.001). Further, the presence of chromatine remodeling gene mutations (BAP1, ARID1A, PBRM1) tended towards longer recurrence-free survical (p=0,09). Some diagnostic circulating miR such as miR21 and miR221 were not associated with survival. Third, in contrast with intraoperative transfusion, the occurrence of severe morbidity (Dindo-Clavien grade > 2) was independently associated with shorter overall survival (p=0.002).Conclusion. Nomograms outperform conventional staging sytem. Preoperative prognostic estimation is feasible and reliable using imaging. Identifying new prognostic biomarkers would help refining preoperative prognostic estimation

Full textIn many industrial sectors, system miniaturization becomes mandatory, allowing reducing occupied space, weight, price, power and material consumption. For this, manufacturers use Micro-Electro- Mechanical Sytems (MEMS). However, MEMS devices have several reliability issues due to their numerous failure mechanisms, which have an impact on the availability of systems where they are utilized. Therefore, it is important to monitor these micro-systems, to anticipate their failures and to perform appropriate actions to maximize their lifespan. One possible solution is to develop the Prognostics & Health Management (PHM) for MEMS. The thesis deals then with the prognostics and the study of MEMS health state and the post-prognostics decision making in systems containing these micro-systems. The aim is to make a MEMS-based system distributed and intelligent by integrating modules of health state assessment and prediction and capacities of self-adaptability dependent of the tasks performed by the system. Firstly, a hybrid prognostics approach for MEMS based on the particle filtering is proposed. Secondly, and to better use the results of this approach, a post-prognostics decision strategy in MEMS-based distributed systems is introduced. This strategy is based on a distributed decision algorithm. The performance of the prognostics approach and the post-prognostics strategy is validated on a real application consisting of a modular conveyor based on distributed MEMS. A complete PHM cycle is thus performed: from data acquisition to decision making

Full textThis thesis focuses on the problem of the systems prognostic. More precisely, it is dedicated to stochastic systems and two main contributions are proposed. The first one is about the prognostic of stochastic systems based on the expert knowledge and the proposed approach consists in assessing the system availability during a mission. This mission is supposed to model the user profile that express the environment in which the system will evolve. We suppose also that this profile is given through a partial knowledge provided by the expert. In fact, since the complexity of systems under consideration the expert can provide only incomplete information. The aim of the contribution is to estimate the system’s damage trajectory and analyse the mission success. In this case, a three steps methodology is proposed. The first step consists on estimating the environment probability distribution. Indeed, a probabilistic method based on maximum relative entropy (MRE) is used. The second step is dedicated to the damage trajectory construction. This step is performed by using a Markov Chain Monte Carlo (MCMC) simulation. Finally, the prediction of the mission success is performed. Note that, the models describing the damage behaviour, and in order to be more realistic, is supposed to be stochastic. The second contribution, concerns the model-based prognosis approach. More precisely, it about the use of the Bayesian filtering on the prognosis problem. The aim of the proposed approach is identify the damage parameter by using an Ensemble Kalman Filtre (EnKF). Then, estimate the RUL based on the damage propagation. To illustrate our contributions, a series of examples is treated

Full textThe short-term prognosis of patients with onco-hematological diseases and neutropenia admitted to intensive care has significantly improved over the last two decades. This progress is the fact of a significant diversification of the armamentarium on oncology and hematology but also a better management of these patients in the ICUs. Our research has focused on the outcome of these patients and its prognostic factors. In this context, we have conducted several prognostic observational studies of neutropenic patients admitted to intensive care units. We showed that factors independently associated with hospital mortality were the bone marrow transplantation, the use of invasive mechanical ventilation, the use of renal replacement therapy and a positive microbiological documentation. Moreover, in neutropenic patients admitted to intensive care for severe sepsis / septic shock, factors independently associated with ICU mortality were inappropriate initial antibiotic therapy, a delay of antibiotic treatment > 1h, a positive microbiological documentation with non-fermenting gram negative bacilli, a high SOFA score on admission in ICU. The de-escalation of initial antibiotic treatment feasible in 44% of cases had no significant impact on the short and long-term outcomes. Otherwise, in neutropenic patients admitted to intensive care for acute respiratory failure, the only independent factor associated with hospital mortality was the need for mechanical ventilation, while the use of corticosteroids in the days before ICU admission and a admission during neutropenia recovery period were protective. Finally, we have shown in a recent review of the literature that the outcome of hematology-oncology patient admitted to intensive care had improved over time and that neutropenia did not seem to be a prognostic factor in this context. In conclusion, we have shown that the neutropenic patient is at high risk of severe infectious,respiratory and immunological complications. These complications significantly impact the outcome of these patients. Our results could lead to the planning of several randomized trials in neutropenic patients admitted to intensive care in particular about the escalation antibiotic in sepsis and oxygentherapy strategies for respiratory distress

Full textIntroduction : La protéase High Temperature Requirement Factor A1 (HtrA1) pourrait être associée au pronostic du cancer de l’ovaire (CO). Objectif : Évaluer l’effet de l’expression de HtrA1 dans des tissus tumoraux sur le pronostic des femmes avec un CO séreux. Méthodes : Une étude de cohorte a été menée chez 122 femmes ayant un CO séreux traitées au CHU de Québec entre 1993-2006. Par immunohistochimie, l’expression de HtrA1 a été mesurée de façon visuelle et informatisée (% noyaux positifs). Des risques relatifs (HR) de progression et de décès ont été estimés avec le modèle de Cox multivarié. Résultats: Un faible pourcentage de noyaux marqués par HtrA1 était associé à une diminution des risques de progression (visuel HR=0,66, p=0,04, informatique HR=0,63, p=0,03) et de décès (visuel HR=0,69, p=0,09, informatique HR=0,56, p=0,01). Conclusion : La sous-expression de HtrA1 était associée à un meilleur pronostic des femmes avec un CO séreux.
Background: The protease High Temperature Requirement Factor A1 (HtrA1) might be associated with prognosis in ovarian cancer (OC). Objective: To evaluate the effect of HtrA1 expression in tumoral tissues on prognosis of women with serous OC. Methods: A cohort study was conducted among 122 women with a serous OC treated at the CHU de Québec between 1993-2006. Tissue microarrays were immunostained for HtrA1. HtrA1 expression was assessed visually and by digital image analysis (% of positive nuclei). Cox regression multivariate models taking into account standard prognostic factors were used to estimate adjusted hazard ratios (HR) of progression and death. Results: Low percentage of HtrA1 marked nuclei was associated with lower risks of progression (visual HR=0.66, p=0.04, digital HR=0.63, p=0.03) and death (visual HR=0.69, p=0.09, digital HR=0.56, p=0.01). Conclusion: Nuclear downregulation of HtrA1 was associated with a better prognosis in women with serous OC.

Full textBackground: The low frequency of spontaneous intracerebral haemorrhage (ICH) and its high mortality rate may explain the paucity of data in long term outcomes. The main objective was to study long term prognosis of ICH through the prism of their natural history.Methods: Our study populations were based on the PITCH (Prognosis of IntraCerebral Haemorrhage) cohort which is an observational study that included consecutively adults admitted at the Lille University Hospital for spontaneous ICH between 2004 and 2009. We aimed to determine (i) the incidence of new onset dementia and its clinical and radiological predictive factors; (ii) the prevalence of cortical superficial siderosis (cSS) and its associated factors; (iii) predictive factors of recurrent ICH.Results: We showed that the risk of new onset dementia is substantial after spontaneous ICH. Predictive factors of new onset dementia such as ICH lobar location and cSS suggest the implication of underlying cerebral amyloid angiopathy. We found that one out of five patients had cSS on baseline MRI. cSS was a strong predictive factor of recurrent ICH. Conclusion: These findings are of immediate clinical relevance in the management of ICH patients and will allow to adequately inform patients and caregivers. These results may provide additional information on ICH recurrence risk assessment and may contribute to the development of future therapeutic strategies

Full textCystic Fibrosis is unfortunately an incurable inherited disorder. Despite real progress in research, it is essential to always have a better understanding of the disease in order to provide suitable treatments to patients. Current treatments mostly aim to reduce the disease symptoms without curing it. Lung transplantation is proposed to cystic fibrosis patients with terminal respiratory failure with the aim of improving life expectancy and quality of life. However, criteria for referring patients for lung transplantation still vary widely among transplant centers. It is necessary to guide clinicians in identifying in a good way patients requiring an evaluation for lung transplantation. It is thus important to clearly identify prognostic factors related to lung transplantation and to predict in a good way the occurrence of this event in patients with cystic fibrosis. The aim of this work was to develop prognostic tools to assist clinicians in the evaluation of different therapeutic options related to lung transplantation. First, we reevaluated prognostic factors of lung transplantation or death in adult with cystic fibrosis. indeed, therapeutic progress in patients with cystic fibrosis has resulted in improved prognosis over the past decades. We identified prognostic factors related to the current state of research in the cystic fibrosis field. We further developed a joint model with latent classes which provided dynamic predictions for lung transplantation or death. This model identified three profile of the evolution of the disease and was able to update the risk of lung transplantation or death taking into account the evolution of the longitudinal marker FEV1 which describes the lung function. These prognostic models were developed using the French cystic fibrosis registry and provided good predictive accuracies in terms of discrimination and calibration

Full textStable or stabilized coronary artery disease patients are at high risk for cardiovascular events. They represent a heterogeneous population. The clinical presentation, the context and the prognosis can be extremely variable from one patient to another. However, according to the international guidelines, those patients should be given a relatively comparable treatment based on clinical trials realized in restricted subpopulations of stable and unstable patients. Most of these trials are old, and no longer correspond to the current management. Specifying the determinants of the prognosis of this population, and in particular the therapeutic strategies, is a major challenge.The antagonist receptors of renin-angiotensin system (ACEI/ARB) are a part of the treatment of any coronary artery disease patient. Yet their interest in the prognosis of this population without left ventricular dysfunction in association with antiplatelet agents and statins is uncertain.The contemporary REACH registry has assessed the impact of ACEI/ARB in this population with a 4-year of follow-up. The statistical methodology used was based on the propensity score. After adjustment or matching with the propensity score, there was no benefit of ACEI/ARB on the primary endpoint of cardiovascular death - MI - stroke. No benefit was found on the secondary endpoint of cardiovascular death - MI - stroke - hospitalization for atherothrombotic events. No benefit was found on the tertiary criteria including individually each of the secondary endpoints and on any cause mortality. Finally,there was no clear benefit in the analyzes subgroups. These results were consistent when the analyzes were performed for ACEI alone or for ARB alone. They were also supported by sensitivity analyzes.These data should be confirmed or reversed in an independent cohort. This will be one of the many objectives of the CLARIFY registry, that enrolled 32,703 stable or stabilized coronary artery disease patients. The 5-year follow-up is complete. In this international contemporary registry, the overall 5-year rate of total mortality was 7.9%, non-cardiovascular mortality was 5% and cardiovascular mortality was 2.9%. A cardiovascular event including myocardial infarction (fatal or not), unstable angina, coronary revascularization by angioplasty or bypass surgery occured in 15.9% of patients.Like ACEI/ARB, the impact of betablockers on the management of stable or stabilized coronary artery disease without left ventricular dysfunction is also controversial. This drug class is being evaluated in CLARIFY. The analyzis takes into account the type of beta-blocker, the prescribed dose, any intolerance leading to changes in their use, the history of a myocardial infarction, and the left ventricular ejection fraction.CLARIFY will help to more define the determinants of the prognosis of stable coronary artery disease, with a more particular focus on symptomatic or not, ischemic or not, and revascularized or not, in order to better understand the mechanisms responsible for cardiovascular events, and evolve towards a more personalized and cost-effective care

Full textFaults diagnosis and prognosis of electrical drives play a key role in the reliability and safety of production tools especially in key sectors (military, aviation, aerospace and nuclear, etc.). The research presented in this thesis aims to introduce new methods for faults diagnosis and prognosis of an induction motors and roller bearings. These methods use measured data collected from sensors placed on the system (induction motor, roller) in order to construct a feature vector which indicates the state of the system. Supervised and unsupervised classification methods are developed to classify measurements (observations) described by the feature vector compared to known or unknown operating modes, with or without failures. Defects were created in the rotor and the bearing of the induction motor, fed by a voltage inverter. The unsupervised classification technique, based on artificial ant-clustering, allows analyzing the unknown and unexplored observations to highlight classes with similar observations. This allows improving the classification and the detection of new operating modes. The supervised classification, based on hidden Markov models, allows associating a degree of similarity when we affect an observation to one or more classes. This defines a reliability index which allows the detection of new operating modes. These methods are not limited to diagnose faults; they can also contribute to the prognosis of faults. Indeed, the prognosis can be defined as an extension of the problem of diagnosis. The prognosis of faults is carried out by three methods based on hidden Markov models for the detection of an impending failure and by two methods based on the neuro-fuzzy system (ANFIS for Adaptive Neuro fuzzy Inference System and the neo-fuzzy neuron) to estimate the remaining time before its appearance. A set of historical data collected on roller bearings is used to validate the proposed methods. The obtained results show the effectiveness of the proposed methods for faults diagnosis and prognosis of electrical drives
