Evaluating Surgical Outcomes: A Systematic Comparison of Evidence from Randomized Trials and Observational Studies in Laparoscopic Colorectal Cancer Surgery

Martel, Guillaume 10 January 2012 (has links)
Background: Laparoscopic surgery for colorectal cancer is a novel healthcare technology, for which much research evidence has been published. The objectives of this work were to compare the oncologic outcomes of this technology across different study types, and to define patterns of adoption on the basis of the literature. Methods: A comprehensive systematic review of the literature was conducted using 1) existing systematic reviews, 2) randomized controlled trials (RCTs), and 3) observational studies. Outcomes of interest were overall survival, and total lymph node harvest. Outcomes were compared for congruence. Adoption was evaluated by means of summary expert opinions in the literature. Results: 1) Existing systematic reviews were of low to moderate quality and displayed evidence of overlap and duplication. 2) Laparoscopy was not inferior to open surgery in terms of oncologic outcomes in any study type. 3) Oncologic outcomes from RCTs and observational studies were congruent. 4) Expert opinion in the literature has been supportive of this technology, paralleling the publication of large RCTs. Conclusions: The evaluation of laparoscopic surgery for colorectal cancer in RCTs and observational studies suggests that it is not inferior to open surgery. Adoption of this technology has paralleled RCT evidence.

A methodology for creating expert-based quantitative models for early phase design

Engler, William O., III 08 April 2013 (has links)
Early systems engineering and requirements definition requires quantitative information about potential solutions prior to having sufficient information or time to develop detailed models. This research develops and demonstrates a transparent and repeatable process for rapidly creating quantitative models that leverage existing expert knowledge. This process is built upon established modeling frameworks and current literature for low fidelity modeling and hierarchical expert-based methods. The process includes system definition using interactive morphological analysis and gathering information from subject-matter experts with computer-based interfaces in order to create a series of linear performance models. Available volunteers provided data for a relevant aerospace design to test the process as a whole and several hypotheses about specific methodological decisions made during the development. The collected data was analyzed for similarity among participants and for similarity to model parameters of an existing trusted truth model. The results of the analysis demonstrated the ability for expert-based models to accurately match the behavior of the truth models and of historical data.

Risk assessment model for the custodial transfer of mined land to grazing

Robert Maczkowiack Unknown Date (has links)
Open cut coal mining in the Bowen Basin of central Queensland had disturbed in excess of 55,000 ha by the turn of the 21st century and 72,000 ha by 2006. Strong export demand in recent years (since approximately 2000) has led to greater production from existing mines and to a proliferation of new ones. Therefore, over the ensuing decades, the level of mining activity can be expected to increase substantially the areas of erstwhile agricultural land that are disturbed. As mines exhaust their resources, companies will be obliged to achieve acceptable end uses for the various domains at those sites. The possibility of having successfully rehabilitated domains at selected sites certified on a progressive basis holds some appeal. While all stakeholder groups find a return of the land to its prior use (extensive cattle-grazing) an appealing goal, mining companies walk a tight-rope. The legislation under which the early mines were established does not bind them as tightly to the environmentally friendly outcomes as applies to new mines. Nonetheless, recent legislative trends as well as companies’ own policies, encourage them to exceed society’s environmental expectations. Regardless of the end use that is designated, relinquishment is permitted only subject to a satisfactory assessment of the risks to its sustainability. Cattle-grazing is considered as a suitable end use, partly because the return of mined land to its prior use is preferred to its designation to some other use and partly because cattle could serve to reduce the bulk of pasture growth that occurs at some sites, reducing the risk of erosion if an intense fire were to occur followed by heavy rain. Graziers’ primary motivation for seeking tenure of mined land is financial. Factors that determine both a site’s productivity and its commercial ‘worthwhileness’ are examined in this research. The major focus of this research however, is the style of management that the custodial grazier may employ. Since any future custodian is likely to be a local landholder (perhaps the grazier family from whom the land was originally acquired for mining some decades earlier), it is the management style of local farmers that is of primary interest. Some graziers use the land more intensively than others: some with more sensitivity than others. Since the reconstructed landscape is inherently more fragile than undisturbed land, differences in management style could be critical to the sustainability of grazing. Factors driving, or at least being associated with, farmers’ land management decisions were identified from prior research as draft components of a risk assessment model for grazing. A survey of the characteristics and circumstances of Bowen Basin graziers was then conducted with a view to modelling their influence on graziers’ land management style. The survey ascertained the prior probabilities among the target graziers of the elements being modelled. An estimate of the role of these factors in shaping land management decisions was then obtained by eliciting the opinions of industry experts. These processes allowed development of a predictive model that estimates the likelihood of conservative and sensitive land management under various scenarios of site characteristics and grazier-based factors. Output from the model showed that the capital circumstances of a grazier’s business have an influence over the predicted management style of 25% of the difference between best-case and worst-case scenarios. There is a 17% greater likelihood of low-risk grazing where a grazier strongly wants tenure of the land for reasons that go beyond financial gain. The grazier’s underlying values and attitudes to land management account for a further 14%, followed by the operational structure of the business (12%), and the external climatic and economic environment (9%). Interventions that mining companies could implement to increase the likelihood of low-risk management has an influence of 23%. The credibility of the model’s output was evaluated by reference to real-life experiences of graziers who have managed cattle on mined land and their miner counterparts. Consistency of opinion among the consulted experts also contributed to the confidence that can be placed in the model’s findings. The model identifies the sources of risk if currently available mined land is used for grazing. It improves understanding of the situation in a holistic manner, and predicts the likelihood of low-risk grazing management under scenarios of interest to the user. The model identifies actions that mining companies could take to reduce risks associated with graziers’ management style. The model may also guide future rehabilitation work by highlighting features of rehabilitation that would make them more suited to commercially feasible and low-risk cattle production – or by purposefully and transparently planning for cattle-grazing not to be the designated end use.

Incertitude des données biomécaniques : modélisation et propagation dans les modèles de diagnostic des pathologies du système musculosquelettique / Uncertainty of biomechanical data : modeling and propagation in the diagnostics models of diseases of musculoskeletal system

Hoang, Tuan Nha 16 December 2014 (has links)
Les pathologies du système musculosquelettique concernant les déformations / anomalies osseuses et musculaires (e.g. paralysie cérébrale) ont un fort impact sur la qualité de vie des personnes concernées. Les objectifs de la thèse sont d’approfondir les études précédentes en intégrant la modélisation de l’incertitude des données biomécaniques et biomédicales dans les modèles de diagnostic prédictif des pathologies du système musculosquelettique. L’intervalle a été choisi pour représenter l’incertitude des données biomécaniques. Ce formalisme est simple et peu coûteux sur le plan du calcul. Les données (physiologiques, morphologiques, mécaniques et analyse du mouvement) ont été recueillies à partir de la littérature en utilisant les moteurs de recherche des articles scientifiques fiables pour établir un espace d’incertitude. La nouvelle méthode de classement (nommée US-ECM) proposée est une méthode de classement semi-supervisé qui utilise la partition crédale pour représenter les connaissances partielles sur les clusters. L’utilisation de la fonction de croyance pour représenter ces éléments de connaissance permet de les combiner d’une manière souple et robuste. De plus, l’extension de cette méthode avec un espace d’incertitude multidimensionnelle a montré la meilleure performance par rapport à la version originale. L’analyse des avis d’expert permettra d’inclure ou d’exclure les sources de données selon leurs niveaux de fiabilité. Ensuite, le modèle de regroupement (US-ECM) développé sera appliqué sur une nouvelle base de données pour évaluer l’impact de la fiabilité des données sur la performance de diagnostic. / The aim of the project is to investigate the modeling of the reliability/incertitude/imprecision of biomedical and biomechanics data (medical images, kinematics/kinetics/EMG data, etc.) and its propagation in the predictive diagnosls models of the disorders of musculoskeletal systems. These diagnosis models will be based on multimodal and multidimensional patient data (3D medical imaging, mechanical data,dinical data,etc.). The literature-based data have been collected to estabish an uncertainty space, which represents fused data from multiple sources, of morphological, mechanical, and movement analysis properties of the musculoskeletal system from multiple sources (i.e. research papers from Science Direct and Pubmed). After that,a new clustering method (US-ECM) is proposed for integrating fused data from multiple sources ln form of a multidimensional uncertainty space (US). Reliability of biomechanical data was evaluated by a fusion approach expert opinion. Reliability criteria of a data source (ie scientific paper published) focus on the technique used the acquisition protocol and measurement and the number of data. A system of questionnaires was developed to co!lect expert opinion. Then, the theory of beliet functions has been applied to merge these opinion to establish a confidence level each data source.

Vybrané aspekty domácího násilí v soudních spisech a psychologických znaleckých posudcích / Selected aspects of domestic violence described in court files and psychological expert opinions

Kolková, Alžběta January 2017 (has links)
The diploma thesis titled "Selected aspects of domestic violence described in court files and psychological expert opinions" deals with forensic - psychological issues. The theoretical part defines domestic violence, its forms and types. There is also space for individual aspects of domestic violence, including treatises on victims and perpetrators of domestic violence, related myths and consequences. This chapter also covers the issue of how to help. A separate part deals with the court file, its content and composition. The expert opinion, its assignment and content is then devoted to the conclusion of the theoretical part. The empirical part, focused on the examination of selected aspects of domestic violence, was based on an analysis of court files containing the psychological expert opinion in cases of abuse under §198 and §199 of the Criminal code. Keywords: Domestic violence, Court files, Expert witness psychologist, Expert opinion
