Ishak, Ounay. "Magnetic resonance cavitation imaging for the monitoring of ultrasound therapies." Electronic Thesis or Diss., Strasbourg, 2024. https://publication-theses.unistra.fr/public/theses_doctorat/2024/ISHAK_Ounay_2024_ED269.pdf.
Full textThis thesis deals with the monitoring of ultrasound therapies using Magnetic Resonance Imaging (MRI), more specifically, localized drug delivery triggered by cavitation phenomena related to the presence of microbubbles (MBs) in the tissue during sonication. At relatively low ultrasound intensity, MB oscillations allow permeabilizing the tissue to therapeutic agents. However, above a certain intensity threshold, MBs can enter an unstable cavitation regime in which they might cause irreversible damage. Therefore, it is necessary to control the cavitation regime to ensure the safety and the efficacy of drug delivery. Within the framework of this thesis, we propose a new method able to map and characterize cavitation phenomena from MR images in real time. The sensitivity of this method has been validated by the conventional cavitation monitoring method based on the analysis of backscattered ultrasound signals. Finally, this method has shown promising results on swine model in vivo

Full textPulsed cavitational ultrasound therapy (PCUT) is an effective non-invasive therapeutic approach in various medical indications that relies on the mechanical effects generated by inertial cavitation bubbles in a controlled focal area. It’s characterized by a short-pulse high intense focused ultrasound emission with no heating effects. This technology, developed in the 2000’s, remains however very recent and there is a need to develop new imaging modalities for the guiding and the monitoring of the procedure. In fact, the B-Mode visualization of the bubble cloud is often limited in deep organs such as the liver and the heart and remains qualitative for the operator. Moreover, inertial cavitation remains a three-dimensional phenomenon which awakens the need for a three-dimensional imaging tool development, as for safety reasons it’s essential to be able to precisely place the therapeutic focal spot on the target zone. At this date, there are no international standards for PCUT.PCUT has been proved to be an effective solution for the calcified aortic stenosis (CAS) treatment, and Cardiawave, in partnership with Physics for Medicine Paris and the European Hospital Georges Pompidou, is developing an approach which consists in repairing the aortic valve, not replacing it. No surgery is required, and it could represent an alternative and a complementary solution to current surgical interventions.The present work explores different tools for the guidance and monitoring of the PCUT treatment of CAS.First, a new modality for the cavitation cloud imaging based on a passive coherent acquisition combined with a spatiotemporal filter was developed, adapted to cardiac applications and easily transposable to commercial ultrasound devices. The modality takes advantage of the short-pulses of PCUT, and by knowing the absolute time delays it allows a “pulse-echo” coherent beamforming of the therapeutic ultrasonic field. The modality was first tested in 2D, in vitro and in vivo, then transposed to 3D.Secondly, we developed safety tools to ensure the guiding and the monitoring of the therapy. As cavitation is a three-dimensional phenomenon, following Cardiawave’s device design it was necessary to ensure the sharp positioning of the therapeutic focal spot. A new cardiac probe was designed for the project. B-Mode and bi-plane ultrafast acquisitions were developed and tested. A specific beamforming allowing a sufficient frame rate and adapted to the mechanical specifications of the probe was also set up based on theory and simulations.Simultaneously, PCUT is presented as a potential solution to treat venous thrombosis by creating a channel for blood on the thrombus, using cavitation. We proposed the design of a new therapy transducer adapted to this pathology and allowing to focus high intensity ultrasound at different depths. The design was optimized using simulations. Finally, we integrated the whole robotically assisted PCUT system for the therapy allowing cavitation monitoring and an easy positioning of the target, hopefully easily transposable to clinics

Full textThis study is part of the PHOS-ISTOS project within 7th Framework Program for Research and Development (FP7). The objective of the project is to develop an alternative method for a medical application, Photo Dynamic Therapy (PDT), combining the manufacturing methods of the textile industry with laser sources and optical devices. PDT is an effective, well tolerated and non-invasive treatment procedure. The therapeutic effect of PDT depends on the photosensitizer substance, the oxygenation of the tumor and the dose of light applied. Today, the light used to activate the photo-sensitizing agents in the conventional PDT protocol is delivered by panels consisting of LEDs. However, these panels have disadvantages such as the non-uniformity of the emission of light on the curved surfaces due to their rigidity and the pain caused by the high dose of light during exposure. In order to develop an efficient alternative to LED panels, we proposed to insert Poly(Methyl Methacrylate) (PMMA) optical fibers into a flexible fabric that adapts to the morphology of the human body and that diffuses light from laser sources laterally. In this study, the behavior of optical fibers inserted in woven structures is studied in order to develop the light emitting fabric that diffuses a powerful and homogeneous light. The value of smart textiles has increased over the past fifteen years. This project is integrated into this approach by developing high value-added applications for the medical textile innovation markets

Full textThroughout this PhD thesis, a technique developed at the Institut Langevin called the Supersonic Shear Imaging (SSI) technique, capable of quantifying tissue shear elasticity in real time, was employed for the characterization of biological tissues. Pre-clinical and clinical studies were performed to evaluate the potential of the technique in the monitoring of elastic changes during cancer development and therapeutic treatment. A clinical study was performed on 23 patients presenting breast lesions who underwent chemotherapy treatment at the Institut Curie. The goal of the study was to use for the very first time, 3D-Ultrasound (3D-US) and 3D-Shear Wave Elastography (3D-SWE) during the chemotherapy treatment to estimate tumour volume and tumour global elasticity, respectively. The 3D-US estimated tumour volumes were compared with Magnetic Resonance Imaging (MRI) volume estimations and showed good correlation. The results of the study demonstrated that 3D-SWE allowed the monitoring the tumour reaction to the chemotherapy by offering accurate tumour elasticity measurements in three-dimensions throughout the study. Tumour elasticity was found to be well correlated with the 3D-US and MRI tumour volume estimations. The SSI technique was employed for the monitoring of cancerous tissues, in the frame of two pre-clinical studies performed on nude mice. One of the studies, carried out in collaboration with L'hôpital Européen Georges-Pompidou (HEGP), aimed to understand the pathology underlying stiffness. The SSI technique and US imaging were used to monitor the growth and the reaction to chemotherapy of human carcinomas implanted on mice. The results showed that for this particular tumour model, tumour volume and tumour elasticity were very well correlated. Performed histo-pathological analyses revealed that tumour elasticity also was very well correlated with tumour necrosis and fibrosis. The second pre-clinical study, performed in collaboration with the faculty of Pharmacy of L'Université Paris V Descartes, intended to evaluate the feasibility of using tissue elasticity to assess the effectiveness of an anti-vascular treatment on a particular type of human colon carcinoma implanted in mice. The results did not show a clear elasticity tendency associated to the treatment. In order to study new additional mechanical parameters (apart from tissue elasticity) which allow a better tissue characterization, a method combining quasi-static axial compressions and the SSI technique was developed to retrieve tissue shear nonlinearity. The first known 2D nonlinearity maps were calculated on tissue mimicking phantoms and on ex-vivo beef liver samples with good accuracy.

Full textThe objective of the present work was to evaluate the relevance of capillary electrophoresis (CE) method for the quantification of tyrosine kinase inhibitors (TKIs) in human plasma in the context of TDM. Four TKIs were selected for this study: imatinib mesylate, erlotinib hydrochloride, lapatinib ditosylate and sorafenib.A fast, simple and cost effective CZE-UV methodology for the quantification of imatinib in plasma was first developed using simply ACN precipitation as sample preparation before analysis. A complete study was performed to understand the electrophoretic behavior of imatinib in the presence of salt (from plasma) and ACN in the sample matrix. Then, a thorough study was performed to optimize an easy to use and performing sample pretreatment methodology based on salting-out assisted liquid-liquid extraction (SALLE) for the four TKIs from human plasma. SALLE, which is based on adding high concentration of salt to two miscible liquids, allows to extract in one step TKIs from plasma in an ACN phase with high recovery. The extracted TKIs can then be directly injected for further CZE-UV analysis. The use of ACN as extraction solvent allows to inject up to 80% of the capillary effective volumes. This allows in-line sample concentration through electrophoretic stacking mechanisms. In the perspective of routine use, the SALLE-CZE-UV methodology was fully automated. The analytical performances obtained for the four TKIs are fully suitable with TDM requirements. Finally, the SALLE-CZE-UV was successfully applied for the extraction and analysis of the four TKIs directly from human blood. All the present developments prove that CE is a relevant technique to address many TDM issues

Full textPulmonary rehabilitation (PR) is recommended in the management of subjects with ventilatory impairment to improve their quality of life. Although a large body of evidence support its use, only few subjects benefit from it and the optimal training modality has not been determined yet. In this context, the use of new and existing tools to optimize access as well as the effects of the program are major developments that deserve to be studied. As part of this thesis, we sought to explore these two major issues (1) by considering a rehabilitation model relocated outside the PR centres while assessing the obstacles to this model and (2) exploring the effectiveness of different add-on to PR in further optimizing the benefits of the program. In the first part, we have shown, through several retrospective studies and an original prospective multicentre contribution, that the six-minute stepper test can be used to prescribe endurance training, particularly for those patients with a mild to moderate chronic obstructive pulmonary disease (COPD), but not to prescribe muscle strengthening. Furthermore, we have shown in a cohort of 105 subjects referred for PR that the use of a remote tele monitoring device was feasible, valid and widely accepted. Finally, we explored the prevalence of cognitive dysfunction, another systemic impairment of COPD that could compromise the relocation of the program, and showed that it was a very common condition (around 75% of the subjects) but that it could improve following PR and did not seem to influence the use of a remote tele monitoring device. In the second part, we evaluated the effects of different add-on used to potentiate the benefits of the PR program. In a cross-over study of 21 COPD patients, we showed that non-invasive ventilation did not improve endurance exercise capacity due to technological limitation of the ventilator. Through a multicentre randomized controlled study carried out in 73 patients with severe to very severe COPD, we have shown that neuromuscular electrical stimulation at home, performed in addition to a PR program, did not provide further benefits on quality of life or exercise capacity. Finally, through a randomized cross-over double-blind study carried out in 10 patients, we were unable to show the effectiveness of transcutaneous nerve electrical stimulation in improving their endurance exercise capacity. Finally, in a last part, we highlighted the research currently carried out in our laboratory following the original contributions described during this thesis, as well as new area of research in order to pursue the themes explored. Thus, two systematic reviews and meta-analysis (the first about nasal high flow therapy in subjects with stable COPD and the second about the use of advanced telehealth technologies to deliver PR) will serve as a basis for future research

Full textThe purpose of this dissertation is to characterize hemostasis-related complications in patients supported by peripheral VA-ECMO to improve their prevention and to optimize the antithrombotic therapeutic approaches in use. In a first study, we qualitatively and quantitatively described the composition of thrombi collected from the VA-ECMO circuits. We observed that these thrombi are mainly made of VWF, fibrin and in a lesser proportion of platelets and RBCs. Our quantitative approach also allowed us to demonstrate the presence of NETs while there was no active septic, confirming the possibility of aseptic NETosis under VA-ECMO. By hierarchical cluster analysis, we identified 2 types of thrombi, each of which may be related to a different mechanism of formation. In this study, the location of thrombi on the VA-ECMO circuit did not impact their compositions, highlighting the heterogeneity of thrombi formed within VA-ECMO and the multifactorial mechanisms that support thrombosis in this setting. In a second study, we compared the performance of surface coatings on VA-ECMO circuits to reduce thrombinoformation and its clinical consequences. Two of the most used coatings in daily practice were compared: the phosphorylcholin-based coating and the polysaccharide-albumin-based coating. We observed a higher rate of thrombotic complications in the phosphorylcholin group without any excess bleeding events or mortality in either group. In addition, compared with thrombi from phosphorylcholin-coated circuit junctions, those from polysaccharide-albumin-coated circuits were poorer in VWF. Our work suggests that the level of anticoagulation should be modulated according to the type of coating of the ECMO circuit.The aim of our third study was to identify the most relevant bleeding events that may guide clinical decision-making for more aggressive clinical management and a greater investment in research. To this end, we compared the association between 3 bleeding classifications with 28-day mortality. The ELSO definition already in use and the BARC classification classes ≥ type 2 were associated with 28-day mortality and thus retained as definitions of major bleeding. Laboratory parameters that are predictors major bleeding according to the ELSO definition were decreased fibrinogen, platelet count, and hemoglobin at cannulations. Body mass index and postcardiotomy etiology were also predictive of ELSO major bleeding. In an additional work related to the topic of the thesis, we studied two of the most used laboratory tests for the monitoring of systemic heparin during VA-ECMO, the APTT and the Anti-Xa activity, to identify the most relevant. First, we studied the relationship between these two tests and then analyzed in a second objective the impact of biological influencing factors on this relationship. Next, we determined their associations with thrombotic and hemorrhagic complications. Although linearly associated, the rate of discordance between their measurements was 39 % for an Anti-Xa reference range of 0.3 - 0.7 IU/mL. Neither APTT nor Anti-Xa was associated with thrombotic or bleeding complications. Taken together, our results highlight the heterogeneity of thrombi from peripheral VA-ECMO, the involvement of numerous causal factors that underline thrombotic and hemorrhagic complications, both not predictable by routine tests. Finally, our work underscored the need for new approaches in thrombotic or hemorrhagic complications management with targets set at an individual level considering both patient and ECMO circuit characteristics

Full textHypoglycemia remains a limiting factor of type 1 diabetes (T1D) treatment. Bedtime snack is often suggested to reduce nocturnal hypoglycemia (NH), but its effectiveness is not supported by evidence-based data. Objective: To determine the association between post-dinner dietary intake and NH occurrence. This is an observational study during which 100 T1D wore a blinded continuous glucose monitoring system and completed a food diary for 72 hours. NH occurred on 28 % of the 282 nights studied. Post-dinner dietary intake was not associated with NH. However, in multivariate models, carbohydrate intake was positively associated with NH (when rapid insulin was injected) and protein intake was inversely associated with NH (without rapid insulin injected). Post-dinner dietary intake does not seem to be associated with a reduce occurrence of NH. Further studies are needed to better understand the impact of bedtime snack on glycemic control and the role of the injection of rapid insulin in the evening.
