Full textAs expected life of a hip prosthesis is still limited, new concepts of implants seek to preserve bone stock of the younger patients. This Ph. D. Thesis aims at developing and evaluating the potential of computer simulations to predict bone adaptation clinically observed with one of these new concepts: "the stemless Munting hip prosthesis" Initially, a retrospective multifactorial study involving a series of 103 young patients operated with the Munting hip prosthesis highlighted the significant influence of the position of the implant and the patient's weight on bone turnover seen on postoperative X-rays. After modification of bone remodeling model developped by Huiskes, a retrospective multivariate finite element 2D model was used to check the good correlation between calculated results and clinical observations. In a second step, we developed a patient specific 3D prospective model using medical imaging of a young patient (16 years) operated with a Munting hip prosthesis. The results have pointed out the inadequacy of a 2D loading model but also the need to modify the bone remodeling law in the special case of a bone growth phase. Our approach, which relied on observation of clinical outcomes, will help contribute to the development of new designs of implants for younger patients. 3D loading conditions and prospective study of additional clinical cases should help improving the proposed patient specific model in the future

Full textTraumatic brain injuries (TBI) are the leading cause of death for people <40 years old. In Canada, the structure of trauma care has evolved independently across provinces during the last decade. However, little is known about the evolution of clinical outcomes. We aimed to assess national and provincial trends in mortality, hospital and intensive care unit (ICU) lengths of stay, and hospital readmissions following a TBI between 2006 and 2012. We conducted a retrospective multicentre cohort study based on TBI admissions across Canadian level I and II trauma centres. Data were extracted from the National Trauma Registry linked to hospital discharge databases. All adults (>16 years old) with an injury severity score (ISS)>12 were included. Generalized linear models were used to evaluate the annual trends of clinical outcomes. Trends were adjusted for physiological variables. Between 2006 and 2012, we observed a global decrease of mortality in Canada (OR=0.95 IC95%=0.92-0.98) mostly driven by Ontario (OR=0.95 IC95%=0.93-0.98). We observed a significant decrease in hospital length of stay in Canada (HR: hazard of being discharged alive from hospital= 1.02 IC95%=1.01-1.02) including a decrease in Quebec (HR=1.03 IC95%=1.01-1.04). Concerning ICU length of stay, we observed a decrease only in Alberta (HR= 1.05 IC95%=1.01-1.09). No statistically significant trend was observed for hospital readmissions. We observed significant decreases in mortality and hospital or ICU length of stay for TBI between 2006 and 2012 in Canada and some provinces. This study could lead to a better understanding of the role of trauma systems on the burden of injuries in Canada.

Full textThis is a randomized double-blind controlled trial involving 70 subjects (in five centers) with an acute syndesmosis rupture, stabilized either with a Tightrope (n=34) or a 3.5mm quadricortical screw (n=36). The two groups were similar regarding demographic, social and surgical data. Subjects with dynamic fixation achieved higher performances as described with the Olerud-Molander and AOFAS scores at 3, 6 and 12 months. Plantar flexion was superior with dynamic fixation at all times. Implant failure was higher in the screw group. Loss of reduction was observed in 4 cases in the static screw group. Reoperation for any cause was more frequent in the screw group. We could not demonstrate major differences in the activity level between the two groups, except that subjects with dynamic fixation returned earlier to their previous sporting activities. Therefore, we concluded that dynamic fixation of acute ankle syndesmosis rupture with the Tightrope gives better clinical and radiographic outcomes.

Full textNumerous and exciting technological innovations were recently developed in radiotherapy. We aimed to assess benefits in two specific fields. 1) Clinical results of Intensity Modulated Radiotherapy (IMRT) applied to the treatment of Head and Neck (H&N) patients. The first study was a long-term monocentric prospective registration of all H&N patients treated with IMRT in our institution. Locoregional control was excellent and toxicities limited. Recurrences were in-field. Dosimetric recommendations (parotids mean dose) were established. The second study assessed the impact of IMRT on health-related quality of life for H&N patients through a multicentric matched-pair comparison with conventional radiotherapy. Outstanding benefits were observed particularly in the fields of salivary dysfunction and oral discomfort. 2) Contribution of Image Guided Radiotherapy (IGRT) in the management of H&N patients treated with IMRT. The first study was a monitoring of delivered dose, using 3D dose recalculation from Megavoltage Cone-Beam CT (CBCT), as a quality assurance measure of a panel of H&N IMRT patients aligned with IGRT. Dosimetric consequences of anatomical changes were assessed. Contribution of color-coded MVCBCT dose-difference maps was studied. The aim of the second study was to quantify the inherent relative mobility between anatomic regions of the H&N area and to assess the dosimetric impact of several different matching procedures. Recommendations for the use of CBCT images in a daily practice were established

Full textBackground Indigenous population have a high incidence of poisoning cases across Canada, which is associated with high morbidity and mortality. A suboptimal provision of health care was suggested to explain suchburden. Unfortunately, very little information is available to describe the specific presentations of poisoning cases in Indigenous populations. There fore, our study aims to assess whether differences exist in the continuum of care of poisoned patients living in rural regions in Quebec, Canada, according to their ethnic origin. Methods We conducted a multicenter retrospective cohort study using data from the Centre antipoison du Québec (CAPQ) between 2016 and 2017. Indigenous poisoned patients were compared to non Indigenous patients living in rural areas. Our main outcome was the duration of involvement by the CAPQ in case management, reflecting the time required to complete toxicological management. Generalized linear regression was used to evaluate differences in the duration of poison center involvement between the two populations. A sex-specific analysis was also conducted. Our secondary outcome was the symptom severity at the conclusion of management. Results Among 362 identified poisoned patients (184 Indigenous and 178 non-Indigenous), we observed no differences in the duration of case management between groups (GMR adjusted = 1.09; [95% CI 0.87;1.38]). Moreover, the sex-specific analysis showed that the association was not significant in either male or female groups. High proportion of patients, in both Indigenous and non-Indigenous groups,showing mild to moderate symptoms at follow-up (78%). One death was registered in each group. The CAPQ received very few calls from the non-conventioned First Nations during the study period. Interpretation We did not observe any difference on the duration in case management of cases between patients living in rural areas. Perceptions of suboptimal care provided to rural Indigenous population are likelyto be related to geographical remoteness rather than ethnicity.

Full textBackground: to fill an aneurysm with detachable platinum coils as much as possible ensure protection against further aneurysm recurrence. As a start, silicone sidewall aneurysm models were filled with various types of coils using conventional endovascular technique. Higher packing ratios (volume of inserted coils / volume of the aneurysm) were obtained with “Soft” coils when compared with “Standard” coils. As well, “Complex-shaped” coils provided with higher packing ratios than did “Helicoidal” coils. Moreover, 3D angiography was found to be more accurate than CT and MR angiographies in the determination of the aneurysm volume. Secondly, in the clinical setting, we used 3D angiography in 255 aneurysm volume measurements and calculation of packing ratios. High aneurysm packing ratios were not found to protect against aneurysm recurrence. Conversely, the aneurysm volume and the duration of angiographic follow-up were found to be statistically determinant factors of aneurysm recurrence

Full textQuality methods of many different types have been used in hospitals. Some specific projects have shown improved results, but there is no strong evidence of the effectiveness of institutionwide quality improvement (QI) programs. This research deals with a specific category of QI programs: those recognised by experts as world class. Three such programs are examined in a case study, investigating their content, implementation, perception and results. The study shows that QI programs can lead to improved clinical results. It documents improvements measured on process indicators for each of the cases and one or a few improved clinical outcomes in two of the cases. The concept of an investment threshold is proposed and explained, a zone of noise delaying evidence of improved results to show, as well as a set of factors increasing or decreasing the effectiveness of QI programs

Full textThe purpose/aim of this thesis is to contribute to the analysis and comparison of PROs (« patient-reported outcomes ») data in oncology clinical trials. The interpretation of such results remains complex and unstandardized. One of the many ways to carry out a longitudinal analysis of PRO data is the time to deterioration (TTD) approach. Within of the scope of this project, some of the research examined which definitions of TTD are used and pointed out that some recommendations have not been followed. Moreover, due to the variability of the definitions in use, the comparison of various results from clinical trials is compromised. A clear definition of what is considered to be a « deterioration » is required for the TTD approach. It will depend on many criteria such as the location of the cancer, the therapeutic setting, the reference score, the minimal important difference perceived by the patient, as well as on censoring rules. Two SAS macros were developed on the TTD method as a way to optimize and harmonize the TTD definitions that are being used, as well as to be able to have comparable results and consequently a way to help standardize those definitions. In this perspective, a study conducted on a cohort of adjuvant breast cancer patients led to more focus on the first deterioration of the patient and the management of non-randomization at baseline. In parallel, this method was also implemented for a randomized phase II trial on patients with metastatic pancreatic cancer. During this trial, the impact of the occurrence of missing data at baseline was handled by applying a multiple imputation based on the Markov Chain Monte Carlo method. These works highlight the need to continue developing a consensus for the longitudinal analysis of PROs data in oncology clinical trials

Full textMany aspects of heart surgery have been carefully studied in the present thesis. The first manuscript touches the important problematic of post-operative stroke. We have analysed in a retrospective fashion the prescription drugs taken pre-operatively in 6,813 patients requiring coronary artery bypass surgery. The aim was to analyse the effect of taking any of the following medications pre-operatively on the risk of post-operative stroke: aspirin, agiotension converting enzyme (ACE) inhibitors, statins, beta-blockers. The combination of taking a beta-blocker and a statin yielded an odd ratio of 0.37 in multivariable analysis, suggesting a strong protective effect. In the second manuscript, I present a study addressing the problematic of moderate ischemic mitral regurgitation. We randomized 31 patients to be treated either by coronary bypass grafts alone or by a combination of coronary bypass grafting and restrictive mitral annuloplasty. Mitral valve regurgitation disappeared immediately following surgery in the annuloplasty group while no impact of coronary artery bypass graft (CABG) alone was noted on mitral insufficiency at the same time point. After one year of follow-up, mild mitral insufficiency was noted to recur in the annuloplasty group while the patients from the CABG alone group remodelled their left ventricle and secondarily decreased their mitral insufficiency grade to the same level as the annuloplasty group. None of the different measurements of clinical evolution differed between the groups at one year. The third study is a 20-year follow-up of patients who had an isolated valvular replacement on the aortic or mitral position with the Carbomedics mechanical prosthesis. This study shows an excellent survival rate with low complications of hemorrhage, thrombosis, thrombo-embolism, reoperation and endocarditis. Noteworthy, a complete absence of structural failure at 20 years.

Full textContext: Transcatheter aortic valve implantation (TAVI) is a relatively young procedure intended to treat patients with severe aortic stenosis who are at high risk for conventional surgery, or inoperable. This procedure underwent multiple technological improvements (successive generations of devices) and multiple technical improvements (simplification of various steps in the procedure). Objective: We intend to describe the clinical impact of a technological improvement (the transition from the second to the third generation of the Edwards device in a high-volume center) and that of a technical improvement (TAVI without pre-dilatation, known as direct TAVI). Methods: We first describe, through a meta-analysis, the state of TAVI at the beginning of its widespread use, in 2012. Next, we describe, through a single-center retrospective study, the clinical impact of the transition from the second to the third generation of the Edwards device in 507 patients. Finally, in a retrospective study with matching, we tested three pre-dilatation strategies: systematic pre-dilatation, selective pre-dilatation, and direct TAVI. Results: In the article describing the initial TAVI experience, the 30-day mortality rate was between 5 and 18%. One-year mortality was estimated at 23% by meta-analysis (random effects model). Stroke rate at 30 days was between 0 and 6.7% and major vascular complication rate was between 2 and 16%. The transition from SAPIEN XT to SAPIEN 3 resulted in a non-significant reduction in 30-day mortality (from 8.7 to 3.5%; p=0.21) and 30-day stroke rate (from 2.8 to 1.4%; p=0.6), and a significant reduction in major vascular complications (from 9.9 to 2.8%; p<0.0001). However, there was a significant increase in permanent pacemaker rate (from 9.8 to 17.3%; p=0.03). Next, we found no adverse effect of performing direct TAVI in terms of mortality or vascular complications at 30 days. We found a trend towards a reduction in stroke rate with direct TAVI (3 vs. 1%; p=0.11), particularly in patients with mildly or moderately calcified valves. However, in those with extensive valvular calcification, the risk of device malposition was numerically higher. In all three studies presented, there was little variation in 1-year mortality (20 to 25%). Conclusions: Short-term adverse events were reduced by the transition towards the third-generation Edwards device. Direct TAVI is feasible and safe. However, both of these improvements have limitations and should be considered carefully.

Full textAbstract - Data regarding surgical management of tricuspid valve disease are based on small cohort studies, and only few of them report echocardiographic results or risk factors for mortality and morbidity. A retrospective descriptive and analytic cohort study was performed in order to analyze the Montreal Heart Institute experience regarding tricuspid valve surgery. Data was extracted from the medical files of patients. During the 1977-2008 period, 792 tricuspid valve repairs and 134 tricuspid valve replacements were performed (median age of patients: 62 years). Operative mortality was 13.8%. Actuarial survival rates at 5, 10, and 15 years were 67±2%, 47±2%, and 29±2%, respectively. At last follow-up, 31% of patients who underwent repair and 12% of patients who underwent replacement had tricuspid regurgitation ≥3/4 (p<0,001). NYHA functional class improved significantly at last follow-up compared to baseline (p<0,001). Propensity score analysis showed that a replacement was associated with increased operative and late mortality rates compared to repair, but with less tricuspid regurgitation ≥2/4 or ≥3/4 at follow-up. The study shows that despite substantial mortality rates, patients experience a significant functional improvement following tricuspid valve surgery. Risk factors for mortality and morbidity are described, and sub-group analyses for triple valve surgery and for isolated tricuspid valve surgery are exposed.

Full textThe development of the nutrigenetics/nutrigenomics (NGx) has generated many expectations since the associated benefits are potentially beneficial for everyone, that is to say, both for healthy and sick individuals. High expectations were also associated with the Human Genome Project (HGP), but as of today only a few have been realized. The HGP thus evolved in a context marked by biohype, i.e., the promotion of exaggerated or unrealistic benefits. Given the importance of expectations associated with the development of NGx and the methodological limitations faced by clinical research conducted in this area, the main objective of this thesis is to determine whether scientific publications reporting results from clinical research conducted in Ngx contribute to the emergence of a biohype phenomenon. More specifically, it will also document the perception of researchers working in this area concerning this phenomenon, try to identify factors that could explain its emergence in scientific literature specific to NGx and suggest ways of actions to mitigate the risks associated with this phenomenon. We first conducted a document analysis of scientific articles reporting results from clinical research in NGx. This revealed that many benefits were promoted in the literature even though the methodological limitations were not necessarily presented or discussed. This observation led us to believe that the promoted benefits were potentially premature. We then sought to validate our findings among researchers working mainly in the field of NGx. Our survey revealed that researchers were generally in agreement with the benefits that we identified in the scientific articles. However, they did not consider that their realization was feasible in the medium term. This survey also revealed that the methodological limitations currently encountered in the conduct of clinical research raised doubts about the realistic outcome of the benefits promoted in scientific articles. These data confirm our observation that a biohype phenomenon is actually emerging in scientific articles reporting results of clinical research in NGx. Besides information about the audiences targeted by researchers and the elements that need to be included in a scientific article, the survey also helped us better understand the advantages associated with the promotion of benefits. The majority of researchers interviewed found that the promotion of benefits in a scientific article would increase the chances of a manuscript being accepted for publication and also foster continuing funding of the research area. In a competitive environment such as biomedical research, the promotion of benefits seems to be an avenue taken to stand out from the field. Although promoting premature or exaggerated benefits are not considered as being scientific misconduct, biohype can cause a weakening of the trust between the public and researchers. Ultimately, it can hinder the continuity of sound scientific research. Based on these findings, one of the strategies that could be use to prevent or mitigate the occurrence of the risks associated with biohype would be to increase awareness of the issue amongst researchers and scientific journal editors. Specifically, we encourage the integration of guidelines on the management of biohype within the codes of conduct that have been put in place to promote good practices in research.

Full textDelivering critical and speech-language pathology care in pediatric settings requires much hard work to reach the desired level of care for children. Several factors contribute to this problem, including resources shortage, pressing needs, and the growing number of ill children. Among the proposed solutions, many believe that synchronous telemedicine can play a role by providing virtual and immediate access to remote skills, with expertise could be made instantly available through a platform that allows efficient communication and is able to support pediatric care. Telemedicine has developed significantly in the provision of critical care and pediatric rehabilitation in terms of diagnosis and therapy. Yet, few studies have examined the feasibility and evaluated the impact of telemedicine on the quality of pediatric critical care and rehabilitation. The main objective of this dissertation was to assess the feasibility of synchronous telemedicine in two pediatric settings—critical care and rehabilitation—and to evaluate its influence on the process of providing pediatric care. The first article presented the results of a systematic review that synthesized studies evaluating the impacts of synchronous telemedicine models on clinical outcomes in pediatric acute care settings. The findings revealed that the use of synchronous telemedicine improved quality of care and resulted in a lower transfer rate, a shorter length of stay, a change in or reinforcement of the medical care plan, a reduction in complications and illness severity, and a low hospital standardized mortality rate. However, the review of the state of knowledge revealed that the quality of the included studies was weak, so more high-quality evidences is needed. The second article, which used a pre/post design, assesses the feasibility assessed the feasibility of home-based telepractice in speech-language pathology (TSLP) and its impact on satisfaction among the children and speech-language pathologists, economic cost, and voice performance. This study showed that TSLP is feasible and that both the children and the speech-language pathologists were satisfied with the service. In addition, the use of TSLP demonstrated more voice improvement at less cost to the parents. The third article evaluated the feasibility of implementing a synchronous telemedicine platform in a pediatric intensive care unit (STEP-PICU). For a STEP-PICU to be feasible and truly helpful, it needs good preparation for the implementation of the telemedicine solution. With competent and autonomous fellows (a fellow is a physician who has completed their residency and elects to complete further training in a subspecialty), the usefulness of an synchronous telemedicine (STM) platform linking off-site pediatric intensivists and on-site fellows in a PICU is limited. This study added that such a service could be more beneficial than the traditional model of care (face to face) for communications with other remote healthcare facilities, where there is a greater need for the expertise of a pediatric critical care intensivist. These three studies allow us to conclude that STM is feasible and can have an impact on the quality of pediatric intensive care and rehabilitation. This thesis underscores the importance of taking into consideration the context in which the technology will be implemented. Treating the PICU and the rehabilitation contexts in the same way does not lead to the same results, and a technological innovation that succeeds in one setting may fail in another.
