Texto completo da fonteOvarian cancers are the second leading cause of death from gynecological cancers worldwide, primarily due to late diagnosis combined with the development of resistance to chemotherapy. Approximately half of these cancers exhibit alterations in homologous recombination (HR), making them sensitive to PARP protein inhibitors (PARPi), which are involved in DNA repair. However, identifying patients who respond to chemotherapy and selecting those eligible for PARPi remains a challenge for clinicians. In this context, the use of patient-derived tumor organoids (PDTO) for predictive functional testing represents a promising approach to guide therapeutic choices in first-line treatment and beyond. The aim of this thesis is to study the feasibility of functional tests based on PDTO to evaluate their potential applicability in precision medicine. Establishing a panel of PDTO derived from various ovarian histological subtypes has demonstrated that these models recapitulate the histological and molecular characteristics of their tumors of origin. Following direct exposure functional tests of the tumor organoids to first- and second-line treatments, we showed that these models exhibit heterogeneous responses to treatments, and particularly that PDTO identified by the predictive test as sensitive to carboplatin mainly originated from responding patients. Additionally, we investigated the results of a functional test assessing HR status, the RECAP test, and demonstrated that this test is complementary to the current method for determining HR status, which relies on NGS sequencing techniques. Although larger-scale investigations are needed to confirm the potential of tumor organoids, these results provide further support for the use of ovarian tumor organoids in the context of precision medicine

Texto completo da fonteSyncope is a sudden loss of consciousness. Although it is not usually fatal, it has an economic impact on the health care system and the personal lives of people suffering. The purpose of this study is to reduce the duration of the clinical test (approximately 1 hour) and to avoid patients to develop syncope by early predicting the occurrence of syncope. The entire work fits into a data mining approach involving the feature extraction, feature selection and classification. 3 complementary approaches are proposed, the first one exploits nonlinear analysis methods of time series extracted from signals acquired during the test, the second one focuses on time- frequency (TF) relation between signals and suggests new indexes and the third one, the most original, takes into account their temporal dynamics

Texto completo da fonteThe main objective of this work was to study the influence of key settings of word predictionsoftware as well as a training program on the use of word prediction, on text input speed in personswith cervical spinal cord injury.Study 1 determined text input speed in persons with cervical spinal cord injury and the influence ofpersonal characteristics and type of computer device on text input speed. Study 2 evaluated theeffect of a dynamic virtual keyboard coupled with word prediction software on text input speed inpersons with functional tetraplegia. Study 3 analysed the word prediction software settingscommonly prescribed by health-related professionals for people with cervical spinal cord injury.Studies 4 and 5 evaluated the influence of the number of words displayed in the prediction list andthe frequency of use setting on text input speed. Finally, study 6 evaluated the influence of a trainingprogram on the use of word prediction software for persons with cervical spinal cord injury on textinput speed.The results showed that only the type of computer device influenced text input speed; voicerecognition software increased the text input speed of persons with cervical spinal cord injury to thatof able-bodied people using a standard keyboard. The influence of the different word predictionsoftware settings (number of words displayed in the prediction list and the frequency of use) on textinput speed, the number of errors or comfort of use, differed depending on the level of injury. Wealso found differences between the perception of the importance of some settings by healthprofessionalsand data in the literature regarding the optimization of settings. Moreover, althoughsome parameters were considered as very important, they were rarely configured. Finally, trainingpersons with cervical spinal cord injury in the use of word prediction software increased text inputspeed.The results of this work highlighted that word prediction software settings influence text input speedin persons with cervical spinal cord injury, however not all professionals are aware of this.Information should therefore be disseminated through professional networks. Further studies shouldaim to improve word prediction software and should also focus on new devices such as tablets andvoice recognition software. Persons with cervical spinal cord injury training programs in the use ofword prediction software need to be developed and validated

Texto completo da fonteFructose intake has increased by up to 50 g per day in the USA and Western Europe. Fructose is increasingly incorporated in beverages, dairy products and canned, baked or processed foods worldwide. Fructose has been shown to trigger or worsen digestive symptoms not only in healthy volunteers, but also in patients with irritable bowel syndrome. The involvement of visceral hypersensitivity has been suspected but has never been assessed. The prevalence of fructose malabsorption in patients with irritable bowel syndrome in Western Europe remains poorly documented, due to the heterogeneity of available tests. Therefore, the first objective of this present work was to assess the prevalence of fructose malabsorption in patients with irritable bowel syndrome. We assessed fructose malabsorption with a fructose breath test, after a 25 g load. We systematically ruled out small intestinal bacterial overgrowth which could promote false positive. In our irritable bowel syndrome patients, 22% had fructose malabsorption. Young, male patients were more likely to have fructose malabsorption. We also assessed the association between fructose malabsorption and other abnormalities. We did not observe any association between low-grade inflammation (with faecal calprotectin dosage) or fructose malabsorption. In contrast, an association between fructose malabsorption and visceral hypersensitivity was evidenced. Low fructose diet is known to improve symptoms in patients with irritable bowel syndrome. The presence of fructose malabsorption could be predictive of the efficacy of a low fructose diet. The second objective of this work was to determine if an abnormal fructose breath test was a predictor of symptomatic response to low fructose diet in irritable bowel syndrome. Our study has confirmed the efficacy of low fructose diet on irritable bowel syndrome. However, the results of the fructose breath test had no impact on its efficacy. One explanation for this result could be the presence of other abnormalities (including visceral hypersensitivity) that were not addressed only with a diet. The last objective of this work was to model fructose malabsorption in mice, in order to identify the underlying mechanisms. We used three models of fructose malabsorption (high fructose diet, invalidation of GLUT5 and GLUT2 coding gene). In these models, fructose malabsorption induced visceral hypersensitivity and increased intestinal permeability, the two abnormalities being reported in irritable bowel syndrome. In our models, there was no low-grade inflammation. Increased elastase activity in mice faeces was associated with visceral hypersensitivity. Protease-activated receptor-2 is known to be associated with visceral hypersensitivity and increases intestinal permeability. Further works are warranted to determine the involvement of protease-activated receptor-2 in fructose malabsorption-associated visceral hypersensitivity. The results of this work underlined the role of fructose malabsorption in irritable bowel syndrome, in the onset of visceral hypersensitivity and increased intestinal permeability. A low fructose diet is not helpful to improve symptoms of irritable bowel syndrome with fructose malabsorption

Texto completo da fonteWorldwide each year, more than 150 000 women die from epithelial ovarian cancer largely due to emergence of resistance to chemotherapy. Approximately half of these cancers display molecular alterations that cause deficiency of DNA repair via homologous recombination (HRD), which confer sensitivity to PARP protein inhibitors (PARPi). To date, there is no test capable of fully identifying the HRD phenotype, thus limiting access to these treatments. In this context, we are developing functional assays based on the use of tumor explant slices and then, on the use of tumor organoids derived from ovarian tumors of chemotherapy-naive or previously treated patients. The culture of explants was unsuitable for this application and we then focused our work on tumor organoids. Tumor organoids were exposed to carboplatin (first-line treatment) and two PARP inhibitors (olaparib and niraparib) used for maintenance therapy. In parallel, we collected clinical data from patients (survival, platinum-free interval, RECIST, treatments) to evaluate the predictive potential of these models. The established tumor organoids responded heterogeneously to different drugs, and our results show that the organoid-based assay is capable of identifying patients highly resistant to carboplatin, suggesting that this functional assay could have a predictive value for patients treated with carboplatin. Regarding the potential of organoids in predicting PARPi response, multiple sensitivity profiles have been identified, but the correlation with clinical response has yet to be determined by studies conducted on tumor samples from patients treated with these drugs
