Full textBenefit of Intensive Care Unit cannot be evaluated by performing randomized controlled trials, and therefore rely on observational studies. Standard analyses cannot be used to draw causal conclusions. Hence, specific statistical methods have been developed over the past decades in order to draw causal conclusions from observational data. Most of these methods rely on modelling the probability of treatment, the most popular being the propensity score. The first part of the thesis is dedicated to a review of the literature focussing on the use of thèse methods in the major Anesthesiology and Critical Care journals. We then focussed on the potential limitations related to the use of the propensity score. We first evaluated the performance of this method in the context of small sample size or low prevalence of the treatment. We then evaluated the generalized propensity approach as an option for the estimation of treatments with more than two categories. The presence of time-dependant confoundings cannot be handled by propensity score methods. Therefore, we evaluated thé use of marginal structural model as an alternative to propensity score in case of time-dependant confoundings. Finally, because all methods based on probability-of-treatment models rely on the hypothesis of absence of unmeasured confoundings, the last section of this thesis was dedicated to the use of instrumental variable approach when the presence of unmeasured confoundings can be suspected

Full textThe issue of how to deal with missing data in epidemiological studies is a topic which concerns every researcher involved in the analysis of collected data and in the interpretation of the results produced by these analyses. And even if the issue of the handling of missing data and of their impact on the validity of the results is often discussed, simple, but not always appropriate methods to deal with missing data are commonly used. The use of each of these methods is based on some hypotheses under which the obtained results are valid, but it is not always possible to test these hypotheses. The objective of this work was (i) to propose a review of various methods to handle missing data used in the field of epidemiology, and to discuss the advantages and disadvantages of each of these methods, (ii) to propose a strategy of analysis in order to study the robustness of the results obtained via classical methods to handle missing data to the departure from hypotheses which are required for the validity of these results, although they are not testable, and (iii) to propose some applications on real data of the issues discussed in the first two sections

Full textInfectious diseases are a major public health problem worldwide. Indeed, infectious diseases were the cause in 2004 to nearly 15 million deaths, whether for emerging pathogens, pathogens known to man for many years or even re-emerging pathogens (2004 Estimation of WHO). It has fallen since we moved, for example, 1.27 million cases of malaria in 2004 to 854,600 in 2013. This downward trend affecting most infectious diseases, but an increase is still the realm of possibility as the demonstrated by the recent outbreak of Ebola.To fight against these infectious diseases, many epidemiological surveillance tools have emerged worldwide. These systems are designed to detect and identify as early as possible of possible epidemic events to promote the warning to the competent authorities and the establishment of counter-measures. The objective of our work was to build and develop an epidemiological surveillance system from the microbiology laboratory data of the Provence-Alpes Côte d'Azur (PACA). This system should enable us to identify possible abnormal events weekly data from the different participating laboratories. The monitoring system has enabled us later to declare several warnings from the Regional Health Agency (ARS) PACA, enhance our work through publications and finally to promote the work of laboratories by providing them a feedback containing the main alarms of the week.The development and automation of the system through the creation of an IT platform developed within the Mediterranean Institute University Hospital Infection (IHU) and by increasing the number of participants and the extension of this system to other regions in France or other countries
Frévent, Camille. "Contribution to spatial statistics for high-dimensional and survival data." Electronic Thesis or Diss., Université de Lille (2022-....), 2022. http://www.theses.fr/2022ULILS032.
Full textIn this thesis, we are interested in statistical spatial learning for high-dimensional and survival data. The objective is to develop unsupervised cluster detection methods by means of spatial scan statistics in the contexts of functional data analysis in one hand and survival data analysis in the other hand. In the first two chapters, we consider univariate and multivariate functional data measured spatially in a geographical area. We propose both parametric and nonparametric spatial scan statistics in this framework. These univariate and multivariate functional approaches avoid the loss of information respectively of a univariate method or a multivariate method applied on the average of the observations during the study period. We study the new methods' performances in simulation studies before applying them on economic and environmental real data. We are also interested in spatial cluster detection of survival data. Although there exist already spatial scan statistics approaches in this framework in the literature, these do not take into account a potential correlation of survival times between individuals of the same spatial unit. Moreover, the spatial nature of the data implies a potential dependence between the spatial units, which should be taken into account. The originality of our proposed method is to introduce a spatial scan statistic based on a Cox model with a spatial frailty, allowing to take into account both the potential correlation between the survival times of the individuals of the same spatial unit and the potential dependence between the spatial units. We compare the performances of this new approach with the existing methods and apply them on real data corresponding to survival times of elderly people with end-stage kidney failure in northern France. Finally, we propose a number of perspectives to our work, both in a direct extension of this thesis in the framework of spatial scan statistics for high-dimensional and survival data, but also perspectives in a broader context of unsupervised spatial analysis (spatial clustering for high-dimensional data (tensors)), and supervised spatial learning (regression)

Full textIn order to demonstrate the practical value of early diagnosis of cryptococcosis, cytomegalovirus (CMV) infection, and hepatitis B virus (HBV) infection during HIV infection in Cambodia, a cohort of 441 Cambodian HIV-infected patients was recruited in 2004 and followed until 2007 in Phnom Penh, in the context of Médecins Sans Frontières and Médecins du Monde antiretroviral drug access programmes. Prevalences, morbidity and mortality were estimated. A high prevalence (59/327; 18. 0%; 95%CI = 13. 9%-22. 2%) of cryptococcosis was observed in patients with a CD4+ T lymphocyte count less than 200/mm3, and the clinical value of systematic screening for cryptococcal antigenemia was demonstrated, as it allows early treatment of infection (28. 8% of cases of cryptococcosis were diagnosed as a result of systematic screening for cryptococcal antigenemia). A cost-effectiveness study (costs in 2009) comparing two cryptococcosis intervention strategies in patients with CD4+ count < 100/mm3 showed that screening for cryptococcal antigenemia and treatment of positive patients presented a better cost-effectiveness ratio (Dollar 180/life year gained) than primary prophylaxis with fluconazole (compared to the absence of intervention). Furthermore, primary prophylaxis presented a reasonable cost effectiveness ratio (Dollar 511/life year gained) compared to the screening. The proportion of patients alive at one year was 71. 9% and 70. 0%, respectively, compared to 60. 7% in the absence of intervention. CMV infection (an opportunistic infection often neglected in poor countries due to the almost complete absence of diagnosis and treatment) was very frequently detected (by real-time PCR) in patients with CD4+ count < 50/mm3 (133/224; 59. 4%; 95%CI = 52. 9%-65. 8%) and was independently associated with excess mortality (highest risk of death for CMV PCR ≥ 4. 2 log10 copies/ml = 3. 6; 95%CI = 2. 0-6. 8). To investigate a pathophysiological basis for these results, HHV-6 replication was studied by quantitative PCR and protein cmvIL-10 screening was performed by quantitative ELISA for C. Neoformans (no association between HHV-6 and cryptococcal infections) and CMV infections (negative correlation between cmvIL-10 level and CD4+ count), respectively. Finally, the proportion of patients presenting active chronic hepatitis B was estimated (45/319; 14. 1%; 95%CI = 10. 3%-17. 9%) and the emergence of lamivudineresistant strains was modelled in the HIV-infected population (7. 8% in co-infected patients) and in the general population

Full textPublic health surveillance is the ongoing, systematic collection, analysis, interpretation, and dissemination of data for use in public health action to reduce morbidity and mortality of health-related events and to improve health. One of its objectives is the detection of unusualevents, i.e. outbreaks, requiring the rapid implementation of countermeasures.The objectives of this work are: (i) to evaluate the main published statistical methods for outbreak detection commonly implemented in different public health surveillance systems, (ii) to propose a new approach based on the optimal combination of statistical methods foroutbreak detection and benchmark it to other methods; and (iii) develop a new statistical method for the etiological analysis of an outbreak from public health surveillance data routinely collected by the system. To achieve these objectives, as a first step, we evaluate the main statistical methods, from a published set of simulated public health surveillance data. Statistical methods have been evaluated for an operational purpose: for all simulated time series, we used the tuning parameters recommended by their authors for each algorithm when available. We propose sensitivity and specificity metrics suitable for these tools. Then we propose an original approach for outbreak detection based on combination of methods selected in the previous step. The performance of this approach is compared to the previous ones according to the methodology implemented in the first step.Finally, we propose a method for the etiological analysis of an outbreak from surveillance data by using statistical models suitable for time series analysis

Full textThe Republic of Congo (RC) where our work took place is a Central African country, sharing borders with the Democratic Republic of Congo, Central African Republic, Gabon, Cameroon, and Angola (Cabinda). In these countries the circulation of arboviruses is documented. In RC, there was little or no documentation on arboviruses prior to our work. We conducted studies of arbovirus seroprevalence in Congolese blood donors for different virus families. We also studied the epidemic caused by the chikungunya virus that prevailed in RC in 2011.Our work have highlighted the high rate of seroprevalence for incriminated major pathogens: 47.2% for Dengue, 27.8% for Yellow Fever, 24.4% for West Nile, 38.8% for Chikungunya and 7.9% for Rift Valley fever. These high seroprevalence rates indicate that these viruses actively circulate in Congo, although no epidemic has yet been reported for some viruses. We have also isolated and genetically characterized a strain named "Brazza_MRS1", belonging to the East Central and Southern African lineage, after the chikungunya epidemic in 2011. The RC has experienced several outbreaks caused by the Ebola virus. We have performed a filovirus seroprevalence study to attempt to better characterize the circulation of filoviruses in asymptomatic Congolese blood donors. The observed rate of seroprevalence of anti Ebola IgG was 2.5% overall (1.6% in Brazzaville, 4% in Pointe-Noire and 4% in rural areas). Identified epidemiological risk factors were the exposure to bats (p <0.001) and birds (p = 0.04). The seroprevalence rate of Marburg virus IgG was low (0.5%)

Full textAlthough considered under control in the second half of the 20th century with the discovery of antimicrobials, infectious diseases remain a serious threat to humanity. Regardless of the state of knowledge we possess on these diseases, all remained unpredictable. To fight this phenomenon, many monitoring strategies have been developed leading to the implementation of various epidemiological surveillance computer programs to detect and identify, as soon as possible, abnormal events including epidemic phenomena. The initial objective of our work was to implement, within the Hospitalo-Universitaire Méditerranée Infection and based on the Microsoft Excel software, two new automated computer-based programs for the weekly automated epidemiological surveillance of abnormal epidemic events using clinical microbiological data from the Timone teaching hospital of of Assistance Publique- Hôpitaux de Marseille (AP-HM). Once completed, we then worked to develop a comprehensive monitoring structure incorporating the investigation and the validation of alarms emitted by the established surveillance systems, the transmission of alerts to the Regional Health Agency (ARS) of the Provence-Alpes Côte d'Azur (PACA), the public dissemination of confirmed abnormal events by publishing scientific articles, and the implementation of feedback and weekly epidemiological bulletins to inform local infectious diseases epidemiological surveillance actors

Full textGaucher disease (GD) is a rare genetic disease. Different biomarkers are altered and patients also have bone events (BE). An enzymatic substitution treatment is available. To analyze the evolution of biomarkers, nonlinear mixed effects models are used and, for BE, frailty models. Those models require specific estimation methods that we assessed by simulation. For frailty models, we compared SAEM algorithm implemented in Monolix to the adaptative Gaussian quadrature (AGQ) implemented in SAS. We also evaluated the powers of the Wald test and the likelihood ratio test of a binary covariate. We then evaluated SAEM algorithm for joint models of longitudinal data and repeated events and evalue the power to detect the link between longitudinal data and repeated events. Results obtained for the estimation of parameters give us few biases and, for frailty models, results are comparable between SAEM and AGQ. We performed an epidemiological description of the French registry of GD. In treated patients, we used a pathophysiological model to describe the evolution of biomarkers under treatment and we analyzed the occurrence of repeated BE. We tested the link between biomarkers and the occurrence of BE. To have a BE before treatment increased three-fold the risk during treatment. We will continue this work with the use of the model we developed to individualize treatment doses
