Texto completoThe plant protection products include a wide range of active substances intended to protect plants against harmful organisms. Their massive use in agriculture in the last decades has led to a widespread contamination of the environment, resulting in the exposure of non-target species. The populations living near fields treated with pesticides are the object of new concerns from researchers and institutions. The first objective of this thesis was to conduct a bibliographic review of scientific publications that have characterized the exposure to pesticides of subjects living near crops and studied its determinants. The results of this review showed that, exposure to pesticides was higher for people living in agricultural areas than for the general population, for many active substances. On the other hand, scientific literature remained incomplete regarding other potential determinants of exposure, such as agricultural practices, meteorological conditions, occupant characteristics and behavior, and building configuration. In order to improve our knowledge of these factors, to conceive eventually preventive actions, an observational study led by the University of Bordeaux was conducted in Gironde (the PESTIPREV study). A measurement campaign was led in thirty homes adjacent to vineyards to collect pesticide residues on outdoor and indoor surfaces of the home, in order to search for eight fungicides. The second objective of the thesis was to identify the determinants of individual non-dietary exposure to agricultural pesticides of the subjects included in the PESTIPREV study. Our results, obtained using structural equation modeling, showed that the contamination of the garden by agricultural pesticides was positively and significantly associated with the area of vineyards within a 500m radius of the house. On the other hand, dispersive meteorological conditions (rain and wind) were likely to limit the observed pesticide concentrations. Inside the dwelling, pesticide contamination was positively associated with the average annual quantity of phytosanitary compounds sold in the postal area of the dwelling, and with the carrying of pesticides from outside by the occupants. On the opposite, the level of household activity, the cleaning frequency, and the frequency of contact with surfaces were associated with a decrease in contamination. These initial results will be completed by future analyses but allow us to consider management actions related to agricultural practices as well as individual prevention measures for rural populations, whose effectiveness and acceptability will remain to be evaluated in future interventional studies

Texto completoThis master's thesis focuses on the study of Aujeszky's disease, its evolution and ways to control it. Aujeszky's disease is caused by the pseudo-rabies virus (PRV). This virus mainly affects pigs and wild boars and can also be transmitted to many other species, including humans. The pseudo-rabies virus can be divided into two main strains with many inter-clade and intra-clade recombinations. Variant strains are currently the most common in the world, involved in interspecies transmission events. The study of this virus has shown that populations carrying the variant strain have increased since 2011. Thus, PRV can still circulate in pig farms and still poses a risk compared to wild life species, such as wild boar, where the virus is frequently detected. The work carried out has allowed us to present the evolution of this virus through genetic comparisons and analyses. This provides a better understanding of the dynamics of transmission and the interspecies evolution of the virus in the same host and between different hosts. This underlines the importance of the establishment of surveillance networks in domestic pig farms as well as in wildlife, as well as the need for strict and appropriate prophylactic measures such as and sacrifices of contaminated animals to prevent the spread of the disease on farms.

Texto completoAlthough there have been various strategies for caries control, and prevalence has been greatly reduced, current methods still cannot eradicate such bacteria-originated of tooth structures, even the restored teeth cannot eliminate the risk of recurrence due to the limitations of contemporary dental materials. Since cariogenic bacteria are prerequisite to caries initiation and progression, developing antibacterial series of dental materials, which can inactivate the bacteria remaining in cavitated tooth surface and those invading from the interface between materials and tooth structure, constitutes a new reasonable way for caries control. An experimental self-etching primer ESP with good etching effect and bond strength was previously developed. The aim of the present study was to investigate the feasibility of antibacterial functionalization of ESP by incorporating inorganic antibacterial functionalization of ESP by incorporating inorganic antibacterial agents (ABAs), which are advantageous over organic ones. Antibacterial activities of ESP containing any one of six different ABAs at different incorporating concentrations, different exposure duration, before or after curing, were examined. The influences of ABA incorporation on the intrinsic physico-chemical characteristics and biocompatibility of ESP were also evaluated. It can be concluded that the here tested ABAs can be effectively incorporated in ESP to provide potential antibacterial activity against cariogenic bacteria, especially S. Mutans, without adverse influences to its inherent physico-chemical properties and biocompatibility. ZnOw AT-83 was the most promising one. The optimal concentration of incorporation ranges from 0. 5% w/v to 2. 5% w/v. The incorporated ABAs were immobilized after curing of ESP; although not so effective in killing the bacteria as before curing, they were deducted to act as a " contact inactivator ", thereby safer and would not lead to the imbalance of oral flora. By the incorporation of inorganic ABAs, it is hopeful to develop antibacterial self-etching primers and series of other antibacterial dental materials, which will favor the maximal conservation of tooth tissues, thereby establishing a substantial basis for a new " preventive-oriented " pattern of caries treatment

Texto completoThe objective of this work was to investigate whether clinical audit was applicable in various settings. We have shown that clinical audit was adequate to improve quality of clinical practice when evidence-based guidelines were available. This was the case for deep venous thrombosis prophylaxis in surgical patients. On the other hand, for medical patients, controversial guidelines that are not based on a high level of evidence did not allow clinical audit to be performed. However, we suggest that quality improvement is possible by the means of problem-solving. To improve daily practice, further research with rigorous methodological patterns (i. E. Epidemiological surveys and/or clinical trials which could eventually lead to evidence-based guidelines) is needed. Our research was conducted using sequences of clinical audit or implementation of practice surveys, critical review of the literature and redesign of quality improvement methods

Texto completoGrapevine is a perennial crop sensitive to many fungal pathogens that require numerous pesticide treatments. However, its uses lead to environmental, human health and fungicide resistance problems. Developing sustainable pest management strategies while keeping a good wine quality is of major importance. In this sense, the use of bio-pesticides products seems to be a promising approach to combine sustainable and intensive agriculture.Two generalist bio-pesticides of great potential have been preliminary identified, forits actions on major fungal diseases of grapevine. The first one is a natural plant extract, with no direct fungicide action but able to systemically stimulate plant defenses. The second one is a microorganism showing strong antagonist fungicide actions, and important ability to stimulate plant defenses. First, the studies conducted in controlled conditions have demonstrated the effectiveness of both products in the suppression of various isolates of Erysiphe necator, Plasmopara viticola, Botrytis cinerea and Botryosphaeriaceae. In parallel,the good efficiencies of these products have been confirmed during vineyard assays. This was especially well demonstrated for the natural extract. As a whole, these studies confirm thepotential of these two products as promising bio-pesticides, of which the strategy of application have been further defined

Texto completoThis work presents the development of enzymatic sensors for the sensitive and selective determination of two organophosphate (OPs) insecticides pointed out by European Community as priority pollutants of surface waters: chlorpyriphos (CPO) and chlorfenvinphos (CFV) (directive EC 2455/2001/E). The very high sensitivity of the sensors has been achieved by combining the use of a genetically-modified (GM) acetylcholinesterase (AChE) with an oriented immobilisation method based on His-Ni affinity on magnetic beads. The selectivity of the system has been obtained by using phosphotriestérase (PTE), an enzyme isolated from Pseudomonas diminuta, which has the capability of hydrolysing certain OPs. A bi-enzymatic sensor associating AChE and PTE has allowed the selective detection of CPO and CFV in simple solutions. The analysis of OPs mixtures has been then performed by using an artificial neural network incorporating three sensors, two mono-enzymatic (wild AChE or GM-AChE) and one bi-enzymatic (GM-AChE + PTE). This system has allowed the specific detection of the two OPs in a wide range of concentrations. A complementary study has shown that immobilizing PTE into a column integrated in a flow system allows the detoxification of surface waters contaminated by the two studied OPs. Finally, the last part of this work has been devoted to the study of a new potential mediator for thiocholine oxidation : PEDOT-PSS

Texto completoThe protein is a key-component of the mitotic surveillance mechanism called the Spindle Assembly Checkpoint which occurs during metaphase-anaphase transition. The SAC is essential in eukaryotes because it ensures the equal transmission of the genetic content between the two future daughter cells. In one aspect of my thesis work, I looked in more detail at the "mitotic timer" function of BubR1, responsible for regulating the basal timing of mitotic division, in Drosophila melanogaster. My results showed that a new Linear motif, localized in the N-terminal domain of BubR1, is involved in the recruitment of Fzy/Cdc20 to kinetochore and consequently in the SAC activation. Moreover, my data provide evidence that the mitotic function of BubR1 is correlated with the level of recruitment of Fzy/Cdc20 to the kinetochore in Drosophila. In the second part, I looked for new partners of BubRI during mitosis. Using Mass Spectrometry, we were able to identify the protein Gnfl as a new BubR1 partner. Moreover, the in vivo analysis of the mitotic phenotype associated with the endogenous loss of Gnfl expression (by Gnfl RNAi expression) has provided new evidence for a role of Gnfl in the spindle microtubules dynamics. Finally, I got interested in the kinase catalytic activity of BubRI which has been so far controversial. I showed by in vitro kinase assays that Drosophila BubRI kinase is indeed catalytically active and that it phosphorylates in vitro two novel substrates, Eip63E and Pontin. Using the same approach as for Gnfl, in vivo phenotypic analysis were carried out in ARNi expressing neuroblasts and preliminary data show defects in the mitotic spindle assembly. Altogether, my data has provided novel insights to better understand the "mitotic timer" function of BubR1 as well as its SAC function during mitosis via the identification of novel BubRI partners and substrates

Texto completoIntroduction: Using a scenario-based technique, this study explored and charted, the positions of the French concerning policies to control tobacco, alcohol and gambling. Method: A sample of 344 adults (including health professionals and lawyers) were polled on the acceptability of the policies of control via a presentation of 54 cases. Each one of them aims at a policy of control relative to potentially addictive consumption (tobacco, alcohol or gambling), including preventive measures, regulation and sanctions. Results: As a result of the typological analysis, eight qualitatively different positions were found. They are presented on a continuum – from total rejection of any policy of control or weak regulation, to favouring strong regulation and severe sanctions. These eight positions are: never acceptable (9%), weak or moderate regulation (5%), moderate regulation associated with strong prevention (11%), moderate or strong regulation (11%), strong regulation with strong prevention (23%), moderate sanctions (9%), severe sanctions (9%) and always favourable (9%). Some participants (14%) are described as « undecided ». These positions were associated with the sociodemographic characteristics of the participants, their political opinions and their consumption habits of potentially addictive products. Conclusion: This study confirms that these practices - smoking, drinking alcohol, and gambling - are no longer considered private but rather have come to be seen as public issues. They are viewed as choices made by society, with implications for the overall social order. A majority of participants agree with the regulations currently applied in France. The type of measure preferred by respondents varies according to the product under consideration as well as the respondent's own consumption patterns (e.g. the more the respondent is a consumer of addictive products, the less favourable he / she is to strong control measures). The analysis of the results shows a convergence in the treatment of these areas of consumption. All participants are in favour of prevention, regardless of the product under consideration. In general, participants confirmed an acceptance of strong regulatory measures, especially for gambling, as well as severe penalties with respect to the consumption of alcohol

Texto completoFilariasis affects more 600 million people in the world and their consequences drove the World Health Organization (WHO) to launch the campaign against filariasis. We studied tools for evaluation and control of these programmes. We measured parasitological indice by thick, thin blood films, skin snips, leucoconcentration and serological indice by ELISA, western blotting, electrosyneresis, immunoelectrophoresis bidimensional, immunochromatographic Test ICT. Antigens fractions of Ascaris lumbricoides (FSom, FLpc, FOg) have been tested. Serums have been gotten to Gabon, to the Comores and Yemen. We showed in assessment, the clinic diagnosis, the leucoconcentration and the skin snip are reference tools. In control, the ICT for detection of circulating antigens of Wuchereria bancrofti and the ELISA are absolutely necessary. The other tools remain difficult to use in mass campaign against filariasis. Ascaris antigen was revealed of a sufficient value for the diagnosis

Texto completoContext: the emergence of infectious diseases is the consequence of dynamic imbalances, within complex ecosystems distributed at a given geographical scale including humans, animals, pathogens and the environment. The increasing globalization of trade implies an increase in international flows of travelers and goods which can promote the spread of infectious diseases. From now on, a health crisis in one region or country can have very rapid repercussions on health and the economy in many parts of the world. Detecting emergences and understanding them through field investigations are essential steps to better control future epidemics and pandemics. Experience: during my professional career, my own work has allowed me to address these three dimensions through three studies that have resulted in publications in international peer-reviewed journals. Study 1) During a nationwide outbreak of Escherichia Coli O104:H4 in 2011, I explored the timeliness of the German surveillance system for detection, and recommended a review of the surveillance system by organizing reporting by doctors and heads of laboratories in a centralized and shared database with different access rights by health services at local, regional and national level. Study 2) Following the influenza pandemic in 2009, I investigated and compared the characteristics of severe pediatric cases in Germany during two epidemic seasons. The unchanged severity of influenza A(H1N1)pdm09 during the first post-pandemic season (2010-11) and the consistently high proportion of possibly hospital-acquired infections highlighted the challenge of preventing pediatric cases beyond the pandemic situation. Study 3) During the Ebola virus (EVD) outbreak in 2014, I evaluated the performance of contact tracing in Liberia as a specific control measure. Despite the unprecedented scale of contact tracing for EVD in Liberia, its ability to detect new cases was limited, especially in urban areas and during the epidemic peak. Discussion: the Covid-19 pandemic has revealed weaknesses in surveillance systems in almost all countries. Lessons learned during previous epidemics and pandemics such as those to which I had been exposed professionally and which I report here have been insufficiently considered. In Africa, estimates of incidence and mortality are respectively 100 times and 15 times higher than official reports. Explanations for these very large differences include weak surveillance systems, insufficient use of contact tracing, screening and diagnostic tests, and lack of access to care. Improving surveillance systems for emerging diseases requires: 1) accelerating the digitization and networking of health information systems at all levels, from health centers and peripheral laboratories to the international level; 2) the capture, effective use and linking of other data sources (communitybased, death registries, animal and environmental data) and the regulated use of the internet and social networks; 3) to strengthen the skills and expertise of field epidemiologists and their networking; 4) to invest in research during and between epidemics; and 5) that donors and governments recognize the inevitability of future epidemics of infectious and other disease conditions with serious consequences, our vulnerability to them and the need to invest in global health

Texto completoAbstract : As the Ordre des infirmières et infirmiers du Québec (OIIQ) has created in 2011 a specialty, making it possible for nurses to develop their expertise in infection prevention and control (IPC). In order to become an IPC clinical nurse specialist, nurses must fulfil a graduate program, which includes a course in microbiology and infectious diseases (MID), among others. Until now, there has been no study evaluating the influence of this training or course on patterns of knowing in nursing for IPC nurses. The goal of this study was to determine the evolution of the patterns of knowing in nursing for IPC nurses who have completed an MID course as part of a graduate program in IPC. A qualitative descriptive evaluation made it possible to determine the evolution of the patterns of knowing. Johns’ model (1995) for structured reflection (MSR) which was used in semi-structured, individual interviews before and after an MID course, helped identify patterns of knowing through a deductive process. Furthermore, Miles and Huberman’s (2003) codification method ensured a semi-inductive process. A horizontal analysis allowed for the detection of recurrence or change in patterns of knowing between each participant’s interviews, as well as between participants. The illustration of the scope of the patterns of knowing in nursing, as defined by Johns and influenced by Carper (1978), as well as the evolution of the patterns of knowing after completing an MID course, were described. The topics that surfaced during the interviews were: the development of a vocabulary fostering team communication, the capacity to go beyond protocols, a greater confidence in their abilities, and the expansion of an ethical view that includes all stakeholders in the community. The benefits of the study are at the level of training and research. Training is represented by the development of nursing perspective in the MID courses and the development of nursing knowledge after completing a course in MID. Finally, towards the research, this has put forward a new approach to assess the contribution of a university course.

Texto completoThe use of pesticides in agriculture has led to enormous progress in terms of yields, pest and disease vector control. However, epidemiological studies suggest that dermal exposure, ingestion and inhalation of pesticides could affect human health through deregulation of immune system cells. Among these cells, macrophages play a key role in anti-infectious and anti-tumor defense and in the maintenance of cell homeostasis. Dysfunction of any of these functions by pesticides could have serious consequences on the initiation and development of infectious, autoimmune, neurodegenerative diseases and cancers. The first objective of this thesis consisted in evaluating the impact of 7 pesticides of different chemical classes, used in fruit arboriculture, on the effector functions of human monocyte-derived macrophages (h-MDM). Among these pesticides, only boscalid had no effect. Thiacloprid promoted the ability of macrophages to produce reactive oxygen species (ROS) and IL-10 in response to an inflammatory stimulus. Chlorpyrifos, thiophanate and ziram increased ROS production at low doses (0.01-0.1 µM) while at high doses (10 µM) chlorpyrifos, ziram, captan and dithianon showed immunosuppressive effects by reducing ROS production and pro-inflammatory cytokines (IL-1ß, TNF-a). These data suggest that exposure to chlorpyrifos, ziram, captan and dithianon may compromise the elimination of microbial pathogens by macrophages.The second objective was to determine the mechanism by which ziram (zinc dimethyldithiocarbamate) inhibits the effector functions of macrophages. To assess the role of zinc in the mechanism of action of this fungicide, the effects of ziram were compared to those of disulfiram, (zinc-free dithiocarbamate) whether or not co-incubated with zinc sulfate. We showed that ziram at 10 µM completely inhibited phagocytosis, oxidative hyperactivity and the production of TNF-a, IL-1ß, IL-6, CCL2 by macrophages under inflammatory conditions. Disulfiram had the same effects only in combination with zinc sulfate (10 µM). The role of zinc in the effect of ziram was also confirmed by the demonstration of induction in macrophages of the expression of (i) antioxidant genes HMOX1, SOD2, CAT, (ii) marker genes for a polarization of macrophages towards an anti-inflammatory phenotype M2 which is often associated with various diseases related to the suppression of host defenses. The third objective was to determine dermal exposure to pesticides. Using monoculture and coculture models associating (or not) keratinocytes and hMDM on either side of a permeable membrane, we showed that dithianon at 10 µM, positively regulated TNF-a, IL-1ß, IL-6, IL-10, TGF-ß mRNAs after 48h in monoculture of keratinocytes and after only 24h in coculture with hMDM. We also established that keratinocytes exposed to 10 µM dithianon triggered ROS production by hMDM after 48 and 72 h of coculture.[...]

Texto completoInvasive aspergillosis (IA) due to Aspergillus has been associated with building construction, which may increase spores emission nearby immunocompromised patients. In 2015, one blocks of 6,000 m2 (60 beds) form our hospital has been entirely demolished. The aim of this study was to evaluate possible association between concentration of A. fumigatus (AF) spores in the outdoor and indoor environment and also with the clinical cases in order to propose some improvements in actuals methods and practices. A daily surveillance of fungal contamination was implemented during 11-months. Environmental survey was realized by air samplings, outdoor and indoor, with an automatic agar sampler. In parallel, surveillance of IA infection cases was conducted by epidemiological investigation. A total of 3885 air samples (1744 outdoor samples and 2141 indoor samples) were collected, allowing calculation of ratios (outdoor vs indoor) to confirm efficacy of preventives measures applied to reduce indoor aerocontamination. Outdoor continuous sampling of Aspergillaceae spores (spore/m3/day) was also realized by a Hirst collector. This collector was useful as alarm system to detect contamination peaks. Similarly, monitoring of meteorological parameters seems to be an interesting tool, to prevent Aspergillus peaks. Finally, 394 isolates of AF, susceptible to antifungals (383 environmental and 11 clinical isolates) were genotyped using MLVA. Analysis of genotypes showed 7 similar genotypes shared by environmental and clinical isolates, suggesting that clinical colonization and/or infection may originate from the hospital environment

Texto completoContext - Most smokers start smoking during adolescence and became smoking dependent before the age of 20. Efforts to fight against smoking in the teenage population have focused largely on programs to prevent rather than quit smoking. On this basis, we implemented an original approach of help to smoking cessation based on a nearness offer associating pharmacologic and cognitive-behavioural strategy with. In a perspective of reducing social health inequalities, we wanted to focus our efforts on a particularly vulnerable population usually not sought, the apprentices. Before expanding such programs, their efficacy must be assessed.Objective- 1) describe the characteristics of smoking in a socially disadvantaged population, the apprentices 2) then highlight the determinants of tobacco addiction in this population 3) and finally meet the main objective which is the evaluation of the effectiveness of offering a smoking cessation program in this population. Method - This quasi-experimental, prospective, comparative study was conducted during two years ofvocational training. The population was composed of all the students from eight VTC (Vocational Training Center) in Lorraine (France). The intervention group (3 CFA) has benefited from the TABADO program, and the control group (5 CFA) received no specific intervention other than educational services generally available. Results - Among the 1,814 students included (770 in the intervention group, 1044 in the control group), 52.0 % were smokers among whom 89.4 % daily smokers, and 5.7 % were ex-smokers. The average age of tobacco use initiation was 12.1 years (SD=2.1) and the average age at inception of regular cigarette smoking was 13.8 years (SD=1.6). Current consumption of the smokers was 12.8 cigarettes per day (SD = 7.8). The average score of smoking addiction was 6.1 (SD = 2.8), according to the Hooked On Nicotine Checklist test (score from 0 to 10 = strongly dependent). Factors significantly associated with dependence were female gender, daily cigarette use, high mean daily cigarette use, co-consumption of cannabis, a smoking environment and a high score of perceived vulnerability. Factors perceived as leading to smoking (automatic gesture, combating stress and supporting morale) were also dependence factors. Of 584 original smokers at 12-month follow-up, 17% in the intervention group were abstinent vs. 11.9% in the control group (univariate p=0.08; adjusted p=0.008; odds ratio [OR] 2.1; 95% confidence interval [CI] 1.2-3.6). Conclusions - Our study has produced original data on the effectiveness of a smoking cessation in a socially disadvantaged young people who had hardly been investigated so far. The combination of proximity to the action of information and psychological support, and an offer of free nicotine replacement therapy seems to be a prerequisite for success.

Texto completoSurgical reconstruction is the common treatment after Anterior Cruciate Ligament (ACL) injury in athletes. It usually requires a long period of rehabilitation and the results in terms of return to sport and re-injury rates are not fully satisfactory. The present work has two aims: the enhancement of recovery after ACL tear and the prevention of initial injury. Firstly, we assessed the kinematic and kinetic alterations during a jump task in patients 7 months after ACL reconstruction. Our findings highlight both a lower jumping performance, and greater asymmetries in patients, particularly considering the total joint mechanical work. The operated leg presents deficits at the knee, hip and ankle joints on parameters such as joint range of motion, joint moments and powers. In addition, changes are also found on the non-operated leg, characterized by a modification of the knee and ankle joint angles, and by a lower total joint moment. Secondly, we focused on ACL injury prevention in female athletes. We determinate a way to detect and reduce the neuromuscular risk factors, including “dynamic valgus”, while increasing jumping performance in young basketball female players. In conclusion, maximizing the recovery after ACL tear requires, in the rehabilitation protocol and the patients follow-up, a particular emphasis on the quality of execution of multi-joint task, on each of both lower limbs. Moreover, the detection and management of the neuromuscular risk factors should be systematized in sports or public at risk in order to prevent ACL injury

Texto completoThe practice of physical activity significantly reduces the risk of stroke. It is also used as a therapeutic strategy to maximize functional recovery during the rehabilitation of stroke survivors. Therefore, it is important to monitor the level of physical activity of healthy people and stroke survivors. Tracking the level of physical activity depends on the availability of valid and reliable tools for measuring and assessing physical activity. Unfortunately, the lack of such tools is observed in Benin, a French-speaking country in Africa. Also, in the circumstances of countries with limited financial resources such as Benin, questionnaires, subjective methods of measuring physical activity, are the most used methods because of their low cost and ease of implementation. The International Physical Activity Questionnaire (IPAQ) is a frequently tool used for measuring the level of physical activity of healthy subjects and different groups of patients. However, this questionnaire, to our knowledge, is not validated in the context of French-speaking African countries as in the context of Benin. The goal of this Master thesis was to adapt and validate IPAQ in healthy people and stroke survivors in Benin. Consequently, following well-established methods, we adapted the IPAQ according to the culture and specific linguistic aspects of French as spoken in Benin. Then, the convergent validity and test-retest reliability of the Beninese experimental version of the questionnaire were examined from a sample of 60 healthy subjects and 60 post-stroke subjects recruited in Benin. The results of the study show excellent convergent validity and excellent test-retest reliability of the Benin version of IPAQ for measuring the physical activity of healthy people and stroke survivors.

Texto completoAs part of the ongoing search for the reinforcement of consent to taxation and, more broadly, to legitimize taxing authority action in general, the public authorities have created and accumulated various processes designed to prevent and resolve the amicable settlement oftax disputes in the domestic order. The aim ofthis is this thesis is the study of the roles of modes of prevention and the non-jurisdictional resolution of tax disputes following the public authorities approach which tend to reinforce the taxpayer's situation in its relationship with the tax administration. lt is specifically designed to demonstrate their contribution in the constant process that wishes to establish a relationship of trust between these actors, while revealing their limitations proved in their implementation and the major issues that will face the taxpayer who resorts to them. The first part will be dedicated to present the development of the modes of prevention and amicable resolution of tax disputes to be an expression of the movement toward improvement of the relationship between the taxpayer and the administration. The second part will deal with the limits of these procedures and the conceivable prospects for their improvement, in particular to counter their drawbacks and thereby protecting the taxpayer

Texto completoAsthma is a chronic disease and its severity is increasing. In France, 2000 asthma-related deaths are reported annually and therapeutic adherence is partly to blame. It is a well-known fact that psychopathological problems may influence adherence, but the literature continues to question the biopsychosocial characteristics linked to this behaviour. The aim of the study is to evaluate the psychosocial aspects that are involved in the adoption of this type of behaviour. Sixty people with severe asthma were followed-up at the University Hospital of Montpellier (6 visits a year by each patient). General therapeutic adherence was assessed by a lung specialist and specific adherence was monitored electronically using a peak-flow meter. Control beliefs about life events (Locus of Control), extraversion and neuroticism were all examined at the beginning and at the end of the study. The stability of these variables was analysed. Perceived control and self-image were evaluated at the end of the study. The results obtained using the evaluation of specific adherence would suggest that external control beliefs and extraversion both interfere with therapeutic adherence. These variables are constant. Self-image also differs depending on adherence. Neuroticim and perceived control are not related to adherence. Results also indicate that age and social desirability are linked to the adoption of this behaviour. Doctors' assessment of general adherence is variable and individuals cannot be distinguished on a psychological basis. The results lead to questions such as the concept and measurement of therapeutic adherence

Texto completoPressure ulcer is a multi-factor complication after spinal cord injury. The risk factors are different between the acute stage and the chronic stage. During the chronic stage, the impact of health behavior risk factors still needs to be determined. Furthermore, most educational therapeutic programs conducted on persons with spinal cord injury are aimed to act on these risk factors allowing the patient to be in charge of his or her health. On a skin level the Skin Management Needs Assessment Checklist is the only tool found in the literature to assess behavioral risks in persons with spinal cord injury. It is a questionnaire in the English language including 12 items exploring skin monitoring, pressure ulcer and wound preventions. It met with our expectations both on conceptual and clinical levels. This work consisted in providing a translation, transcultural adaptation and complete validation of the French version of the SMnac. The revised SMnac obtained after the translation and transcultural adaptation is made of 19 items. Questionnaire's reproducibility is excellent. Construct validity was evaluated with 7 convergence hypotheses and 3 divergence hypotheses and is satisfactory. Internal coherence is high and responsiveness to change, evaluated during the acute phase of SCI management, is also high

Texto completoThis doctoral thesis aimed at synthesizing peptides and analogous peptides with an anti-thrombosis activity profile. The peptides allowed us to study the importance of peptide sequences as well as their structure as recognized by the TIIICBP receptor. The KBGEBGPK and KPGEPGPK reference octapeptides show an anti-thrombosis activity in vitro and in vivo. The incorporation of these reference sequences into the simple trimers increases the anti-thrombosis activity of the octapeptide sequences. However, when the reference octapeptide is incorporated into a peptide that mimics the collagen triple helix, the anti-thrombosis activity is suppressed in favor of a pro-thrombosis activity. The incorporation of a thiouracile-type probe into the side chain of the lysines in the positions 1 and/or 3 of the reference octapeptide sequence does not lead to a major change in the anti-thrombosis activity. This will make it possible to use these analogous peptides as a molecular tool to characterize TIIICBP

Texto completoKnowledge of HIV incidence is essential to provide a timely picture of the HIV epidemie, in arder to target and evaluate prevention efforts. However, current methods of HIV incidence estimation can hardly provide data on current transmission patterns. A new approach based on biological procedures that discriminate recent from long-standing HIV infection has been developed since the mid 1990s. Its major advantage is that it can provide incidence estimates from a single population sample without the need for a longitudinal follow-up. The French national HIV/AIDS case reporting system has included aroutine testing for recent infection since its debut in 2003. The objective of this PhD thesis is to estimate population-based HIV incidence in France by using HIV case reporting data and results from recent infection testing. Its first part is a review of laboratory-based methods for HIV incidence estimation. The second part is dedicated to the calibration of the test for recent infection used in France using a reference sample of population. The third partis giving estimates of population-based HIV incidence in France. Based on this new method applied at a national scale, HIV incidence will be tracked over time in arder to monitor the HIV transmission dynamics in the various risk groups of the population and to better target prevention

Texto completoIn years following the onset of HIV infection, priority was given to therapeutic research. Since the introduction of highly active antiretroviral therapy in 1996, mortality and morbidity related to HIV have decreased dramatically. However, the epidemic remains active, especially among men who have sex with men (MSM), highlighting the need for changes in testing and prevention policies. This thesis presents the evolution of a part of research in epidemiology of HIV in Northern countries, focusing first on HIV treatments effectiveness then moving toward to limitations of current HIV testing strategies, new strategies of HIV testing, and finally addressing prevention. This Ph.D thesis contains five epidemiological studies conducted in France.The first study, conducted in 175 HIV-1 infected antiretroviral-naive patients, showed that lopinavir/ritonavir was efficient regardless to polymorphisms carried by the viral protease.The second study, based on an economic model accounting changes in medical practices and the impact of new drugs, showed that lifetime cost associated with HIV care is €535,000/patient (€320,700 discounted) for a life expectancy of 26.5 years under current conditions. Moreover, it highlighted that annual cost of care increases with late access to care (€21,600/year if AIDS or CD4 count <200 cells/mm3 at HIV care initiation, vs. €19,400 if CD4 count >500 cells/mm3, undiscounted costs).The third study conducted in 1,008 HIV-infected patients newly diagnosed, showed that 93% of patients had seen a general practitioner within 3-year period prior to HIV diagnosis. Of patients enrolled, 82 who sought care for HIV-related symptoms within this period had a missed opportunity for HIV testing proposition. Similarly, 55% of MSM who notified to a healthcare setting that they belonged to this risk group had a missed opportunity for HIV testing proposition. The fourth study assessed a community-based HIV testing strategy targeting MSM (532 MSM tested into the program studied). This HIV testing reached people at high risk of HIV, on third of these was little or not tested in other testing facilities. Among the 15 patients who tested positive (2.8%), 12 (80%) received confirmation and linked to care (median CD4 count =550 cells/mm3). The fifth study, a case-control study conducted in MSM in northern France (53 cases of early syphilis and 90 controls) showed receptive oral sex without a condom and anal sex toy use as the main risk factors for syphilis acquisition. Our results highlight limitations of current HIV testing strategies. They show the importance of promoting routine HIV testing in primary care settings, and extension of testing facilities that target populations with specific risk. In addition, they enhanced prevention for risk reduction measures for HIV and STIs. In the era of effective and well tolerated but expensive antiretroviral therapy, testing and prevention are significant issues in the control of the HIV epidemic

Texto completoThe occurrence of MSDs can be related to the forms of work organization which does not allow operators to regulate their work situations. Acting for MSD prevention in the meat cutting activities, implies the development of their situational operational leeway. The purpose of this work is to describe and analyze the effect of critical situation regulation by subcontractor supervisors on supervised operators work environment. The methodology is based on the analysis of two cases mobilizing interviews, observations of the activity of two subcontractor proximity supervisors and self-confrontations. The “critical situations” regulating processes related to the components of the situational operational leeway of the supervisors and its effect on the working environment of supervised operators was reconstituted. Our results show that in order to create the performance conditions, the supervisors participate indirectly and on condition in designing the environment characteristics of the supervised operators for MSD prevention. These conditions refer to the possibility of developing situational operational leeway which is the combination of individual, collective and organizational components. The regulations are implemented on a vertical plane based on the provision of resources for the development of collective work within the team. On an horizontal plan, it gives place to entraid and cooperation with the team, the operators and the supervisors of user company. These regulatory activities in the "here and now" within the critical situation can also be a way for supervisors to influence more widely their working conditions beyond the scope of the work situation

Texto completoHealth policy of primary but also secondary prevention of cardiovascular diseases appears to be a major stake. The prevention of atherothrombotic disease is based on antiplatelet agents whereas the one of thromboembolic events on the anticoagulant ones. Among the antiplatelet drugs, aspirin has been since the 70s the reference treatment. Since the 80s, the inhibitors of the ADP pathway have corne in addition of the therapeutic arsenal of the antiplatelet strategy. Into this antithrombotic therapeutic class, we focused on pharmacologie specificities of several drugs: aspirin : its mode of action inducing enzymatic inhibition and net receptor inhibition is responsible for the notion of aspirin resistance. Clopidogrel : its metabolism which includes several steps depending of enzymes with inter-individual differences is responsible for variability of response to this drug. This resistance mechanism has been studied using a very specific parameter : quantification of the P2Y12 receptor occupancy. The results have led to hypothesize that this variability is due to inter-individuel variability on the metabolism of esterases. Heparins: heterogeneous mixture of glycoaminoglycanes (GAG), highly negatively charged has a complex pharmacology because of numerous interactions with the circulating proteins, surfaces and their exchanges with endogenous GAG, in particular with those of endothelial glycocalyx. These numerous and complex interactions have consequences in human clinical situations which have been highlighted in the StackEnox study. Finally, vitamin K antagonists (VKA) counteracting alimentary vitamin in competition with functional activation of, not of one, but of many coagulation factors and inhibitors (and even outside) require a monitoring with a narrow therapeutic index, leading us to develop an anticoagulation clinic based on telemedicine and therapeutic education to improve the medical care of the patients receiving anticoagulants

Texto completoAs the world is confronted with an explosion of chronic diseases, patient education which helps people to take an active part in the management of their health seems more and more inescapable today. The therapeutic educational Unit of Basse-Terre hospital, in Guadeloupe, operates a structured program of patient education for the Guadeloupeen diabetics. We realized a transverse study based on individual interviews with patients integrated into the unit between May 2007 and April 2008 to estimate the affects of this program on their management of diabetes. This work is the second study concerning the impact of the program operated by the therapeutic educational Unit. The statistical analyses show a significant improvement of the glycaemic control through a decline of glycated haemoglobin (HbA1c) of 0,76 % on average between MO and M6 for the participating patients in the survey, which confirms after one,year, because between MO and M12 the decline of glycated hemoglobin is 0,93 %. These results seem stable until 2 years after the beginning of the program. We also observed a weight gain of the order of 2,3 kg over an average period of 19 months of observation. As for the food habits, 64 % of the patients who described a food imbalance when they joined the unit, now describe an improvement of their practices after the program. The patients evoke for 95 % of them an improvement of their quality of Iife; a majority of them also tell to have improved their perception self-efficiency in the management of diabetes

Texto completoGambling confronts individuals to at least two paradoxes. The first one refers to control: on the one hand, gamblers think they can control the game in order to increase their chances to win (i.e. the illusion of control) and, on the other hand, they can lose control over their impulses. To gamble safely, gamblers should play in a controlled way instead of trying to control the game. The second paradox is that the gambling operators have financial interests in promoting gambling, but try at the same time to prevent the risks of gambling. In particular, they have to help gamblers to keep control of their impulses. To that end, gambling operators use prevention messages promoting Responsible Gambling (e.g., “So that gambling remains a game”). The central thesis of this dissertation is that these preventive messages often are ambiguous and tend to convey promotional contents rather than preventive ones. The aim of this dissertation was thus to examine the comprehension of messages promoting Responsible Gambling. We studied the ambiguity of their semantic content and the influence of extrinsic factors of the message (i.e. the characteristics of the source of the message and of the receiver) on the understanding of the message. We conducted four experiments online with 1438 participants. Results of these studies show that prevention messages promoting Responsible Gambling have a paradoxical effect on individuals: they are ambiguous (Experiment 1) and individuals understand them as being both prevention and promotional messages (Experiment 2). In a real game situation, messages promoting Responsible Gambling exacerbate risk-taking behavior when compared to non-ambiguous prevention messages (Experiment 3). Moreover, we showed that people better understand prevention messages when they see them as stemming from the government instead of a gambling operator and when the source is perceived as highly credible. However, gamblers’ attitudes toward gambling, familiarity with gambling or their level of risk of pathological gambling does not influence the comprehension of the message in our sample (Experiment 4). This dissertation shows that messages which are currently used by gambling operators are not appropriate to prevent excessive gambling. Our work thus contributes to the improvement of preventive communication strategies of gambling operators and governments

Texto completoIn order to guide policy making in public health, it seems useful to confirm the effectiveness of malaria control interventions (MCI). To achieve this, one may evaluate the impact of a given MCI on the incidence of the disease, for example, but this approach won’t easily disentangle the effects of the intervention from those of other MCIs deployed simultaneously, and from influences of environmental and social factors. Mathematical modelling won’t be helpful in this purpose since it infers the impact from the efficacy measured in controlled trials. The direct estimation of the effectiveness of the intervention under fields conditions, i.e. under the influence of biological, environmental and human factors, is nevertheless possible. In particular, appropriate epidemiological surveys can estimate the association between exposure to MCIs and malaria.The present thesis describes the results of several studies conducted to evaluate the effectiveness of MCIs in Madagascar. This country has the advantage to include constrasted malaria transmission patterns, with areas earmarked for pre-elimination and others with intense and perennial malaria transmission. (...)Overall this thesis proposes a methodology for the evaluation of the effectiveness of MCIs that can be transferred to other settings, and demonstrates the usefulness of this approach. In a global context of stagnating international funding, these results provide valuable information and tools to carry on the fight against malaria
